Adaptación y validación del Voice Handicap Index y su versión abreviada al español rioplatense de Argentina

Objetivo: Este estudio tuvo como objetivo principal validar el Voice Handicap Index (VHI) y su versión abreviada (VHI-10) adaptados al español rioplatense de Argentina, con objetivos específicos centrados en evaluar su fiabilidad y validez. Metodología: La adaptación cultural incluyó técnicas de traducción directa, síntesis y retrotraducción, evaluación de la equivalencia semántica y aplicación a un grupo piloto. Para la validación se evaluó la fiabilidad de ambos índices adaptados mediante la consistencia interna (coeficiente alfa de Cronbach) y la estabilidad test-retest (prueba de Bland-Altman, CCI y r de Spearman). Además, se examinó la validez de criterio y de constructo. 213 sujetos participaron en la validación del índice adaptado de 30 ítems (123 disfónicos; 90 de control); 113, en la del índice abreviado (63 disfónicos; 50 de control). Resultados: Se constituyó el Índice de Desventaja Vocal (IDV) como la versión adaptada del VHI al español rioplatense de Argentina. Ambos índices demostraron excelente consistencia interna (IDV-30 α = 0,96; IDV-10 α = 0,92) y estabilidad y concordancia (IDV-30 CCI = 0,95; IDV-10 CCI = 0,96). Se halló alta correlación entre los puntajes de ambos índices y la autoevaluación de la severidad de la disfonía de los participantes (r = 0,85). Ambos índices demostraron capacidad de diferenciar entre individuos con disfonía y sujetos sanos (p< 0,001). El análisis factorial reveló tres factores para el IDV-30 y un factor para el IDV-10. Conclusiones: El IDV-30 e IDV-10 presentan grados adecuados de fiabilidad y validez. Ambos pueden ser incluidos en protocolos de valoración de la función vocal por profesionales de Argentina.

Aim: This study aimed to validate the Voice Handicap Index (VHI) and its abbreviated version (VHI-10) adapted into Rioplatense Spanish from Argentina, with specific goals centered on assessing their reliability and validity. Methods: Cultural adaptation involved direct translation, synthesis and back-translation techniques, followed by an assessment of semantic equivalence and application to a pilot group. For the validation process, the reliability of both adapted indices was assessed through measures of internal consistency (Cronbach's alpha coefficient) and test-retest stability (Bland-Altman test, ICC and Spearman's correlation coefficient). Additionally, we conducted analyses to asses criterion and construct validity. 213 subjects participated in the validation of the adapted 30-items index, (123 with dysphonia; 90 from control group); 113, in the abbreviated version (63 with dysphonia; 50 from control group). Results: The "Índice de Desventaja Vocal" (IDV) was established as the adapted version of the VHI into Rioplatense Spanish from Argentina. Both indeces exhibited excellent internal consistency (IDV-30 α = 0,96; IDV-10 α = 0,92) and satisfactory stability and agreement (IDV-30 CCI = 0,95; IDV-10 CCI = 0,96). Regarding validity, a strong correlation was observed between the scores of both indeces and the participant's self-assessment of dysphonia degree (r = 0,85). Both indices effectively differentiated between individuals with dysphonia and healthy subjects (p< 0,001). Factor analysis revealed three factors for the IDV-30 and one factor for the IDV-10. Conclusion: The IDV-30 and IDV-10 demonstrate satisfactory levels of reliability and validity. Both indices can be incorporated into the assessment protocols for evaluating the vocal function by professionals in Argentina.

Study on Body Composition of Patients with Diabetes Mellitus by Dual-Energy X-Ray Absorptiometry: A Morphological Study

SUMMARY: Diabetes is a form of endocrine disease. Dual-energy X-ray Absorptiometry (DXA) provides a detailed view of the body composition to find out what makes people with diabetes different from those with other diseases. We scanned 371 patients with DXA to analyze their body composition parameters. Three hundreds and seventy one patients (178 women/193 men), who with different diseases, with a mean±SD Body Mass Index (BMI) of 25.32±8.3 kg/m2 were included. The body composition of 371 patients was assessed. Bone Mineral Density (BMD), Fat Weight, Lean Weight, waist-to-hip ratio, Lean Mass Index (LMI), Fat Mass Index (FMI), the relationship between Fat percentage and BMI were analyzed. The 371 patients included 156 diabetics and 215 non-diabetics. Non-diabetic patients also included 5 obesity patients, 9 patients with fatty liver, 39 patients with hypertension, 22 patients with hyperlipidemia, 18 patients with cardiovascular disease, 11 patients with chest and lung disease, 4 patients with chronic disease, 14 patients with brain disease and 93 patients with other diseases. Among 156 diabetic patients, 129 had VAT > 100 cm2 and 27 had VAT ≤100 cm2. The lean weight (LW) of male diabetic patients was significantly higher than that of female diabetic patients. The fat weight (FW) of female patients with diabetes was significantly higher than that of male patients. The waist-hip ratio (WHR) was 1.37 ± 0.25 in male diabetic patients and 1.18 ± 0.21 in female diabetic patients. Among the 215 non-diabetic patients, the obese and fatty liver patients, which the weight (WT) (obesity: 83.87 ± 8.34 kg fat liver: 85.64±28.60 kg), FW (obesity: 28.56 ± 4.18 kg fat liver: 28.61 ± 10.79 kg), LW (obesity: 52.62 ± 9.64 kg fat liver: 54.29±17.58 kg), BMI (obesity: 28.76 ± 1.88 kg/m2 fat liver: 29.10 ± 5.95 kg/m2), was much higher than other patients. Diabetes patients had less fat mass than non- diabetic patients; the difference was around 2 kg. BMI is also a modest number. BMD doesn't differ all that much. Non-diabetic patients with fatty liver obesity and cardiovascular disease had higher fat mass and BMI than patients with other illnesses. Body composition can provide precise information on the makeup of different body areas, but further in-depth exams are required to ascertain the body's endocrine profile.

La diabetes es una enfermedad endocrina. La absorciometría de rayos X de energía dual (DXA) proporciona una vista detallada de la composición corporal para descubrir qué diferencia a las personas con diabetes de aquellas con otras enfermedades. Escaneamos a 371 pacientes con DXA para analizar sus parámetros de composición corporal. Se incluyeron 371 pacientes (178 mujeres/193 hombres), con diferentes enfermedades, con un Índice de Masa Corporal (IMC) medio ± DE de 25,32 ± 8,3 kg/m2. Se evaluó la composición corporal de 371 pacientes. Se analizaron la densidad mineral ósea (DMO), el peso graso, el peso magro, la relación cintura-cadera, el índice de masa magra (LMI), el índice de masa grasa (FMI), y la relación entre el porcentaje de grasa y el IMC. De los 371 pacientes 156 eran diabéticos y 215 no diabéticos. Los pacientes no diabéticos también incluyeron 5 con obesidad, 9 con hígado graso, 39 con hipertensión, 22 con hiperlipidemia, 18 con enfermedad cardiovascular, 11 con enfermedad torácica y pulmonar, 4 con enfermedad crónica, 14 con enfermedad cerebral y 93 pacientes con otras enfermedades. Entre los 156 pacientes diabéticos, 129 tenían un IVA > 100 cm2 y 27 tenían un IVA ≤100 cm2. El peso magro (PV) de los hombres diabéticos fue significativamente mayor que el de las mujeres diabéticas. El peso graso (FW) de las mujeres diabéticas fue significativamente mayor que el de los hombres diabéticos. El índice cintura-cadera (ICC) fue de 1,37 ± 0,25 en hombres diabéticos y de 1,18 ± 0,21 en mujeres diabéticas. Entre los 215 pacientes no diabéticos, los pacientes obesos y con hígado graso, cuyo peso (WT) (obesidad: 83,87 ± 8,34 kg hígado graso: 85,64 ± 28,60 kg), FW (obesidad: 28,56 ± 4,18 kg hígado graso: 28,61 ± 10,79 kg), PV (obesidad: 52,62 ± 9,64 kg, hígado graso: 54,29 ± 17,58 kg), IMC (obesidad: 28,76 ± 1,88 kg/m2, hígado graso: 29,10 ± 5,95 kg/m2), fue mucho mayor que otros pacientes. Los pacientes diabéticos tenían menos masa grasa que los pacientes no diabéticos; la diferencia fue de alrededor de 2 kg. La DMO no difiere mucho. Los pacientes no diabéticos con obesidad debido al hígado graso y enfermedades cardiovasculares tenían mayor masa grasa e IMC que los pacientes con otras enfermedades. La composición corporal puede proporcionar información precisa sobre la composición de diferentes áreas del cuerpo, pero se requieren exámenes más profundos para determinar el perfil endocrino del cuerpo.

Different Body Partialization Procedures Considering Maximum Strength and Explosiveness: Factorial Analysis Approach

SUMMARY: The aim of this study was to determine the sensitivity of different methods of partialization, in terms of different body component indices in relation to indicators of strength and explosiveness. The research involved 187 subjects who were divided into two groups based on sex. This research consisted of measuring body composition characteristics by multichannel bioimpedance analysis (BIA) InBody 720, as well as contractile characteristics of different muscle groups with tenziometric Dinamometry method. Based on the results of the factor analysis we found that regardless of the sex the most sensitive variable for partialization of absolute body isometric strength variable (ABiS) is partialization by allometric scaling (0.964 for females and 0.947 for males explained factor variance). However, in the case of absolute body isometric explosiveness (ABiE), the results of this study have demonstrated that partialization relative to skeletal muscle mass according to the body longitudinality - skeletal muscle mass index (SMMI) is the methodological choice disregarding the sex (0.982 for females and 0.980 for males explained factor variance). The results of the study have shown that for the purpose of scaling the maximal strength relative to body composition, the allometric method can be considered as a choice, while for the partialization of maximal isometric explosiveness skeletal muscle mass index is the best choice insensitive of the sex.

El objetivo de este estudio fue determinar la sensibilidad de distintos métodos de parcialización, en términos de diferentes índices de componentes corporales en relación a los indicadores de fuerza y explosividad. En la investigación participaron 187 sujetos que se dividieron según el sexo en dos grupos. Esta investigación consistió en medir las características de composición corporal mediante análisis de bioimpedancia multicanal (BIA) InBody 720, así como las características contráctiles de diferentes grupos musculares con el método de Dinamometría tenciométrica. Con base en los resultados del análisis factorial, encontramos que, independientemente del sexo, la variable más sensible para la parcialización de la variable de fuerza isométrica corporal absoluta (ABiS) fue la parcialización mediante escala alométrica (0,964 para las mujeres y 0,947 para los hombres). Sin embargo, en el caso de la explosividad isométrica corporal absoluta (ABiE), los resultados de este estudio han demostrado que la parcialización relativa a la masa del músculo esquelético según la longitudinalidad del cuerpo - índice de masa del músculo esquelético (SMMI) es la opción metodológica sin tener en cuenta el sexo (0,982 para las mujeres y 0,980 para los hombres). Los resultados del estudio han demostrado que para escalar la fuerza máxima en relación con la composición corporal, el método alométrico puede considerarse como una opción, mientras que para la parcialización de la explosividad isométrica máxima, el índice de masa del músculo esquelético es la mejor opción independiente del sexo.

Relación entre índice cintura cadera, índice cintura talla y la Escala FINDRISC en adultos de Guatemala / Relationship between waist-hip index, waist-height index and the FINDRISC Scale in adults from Guatemala

La diabetes mellitus tipo 2 (DM2) es una amenaza para la salud por las complicaciones derivadas de un diagnóstico tardío, donde la identificación oportuna es primordial. Con el objetivo de establecer la relación entre índice cintura talla (ICT), índice cintura cadera (ICC) y puntaje de la escala FINDRISC (Finnish Diabetes Risk Score) como determinantes del riesgo de padecer DM2 a largo plazo, se realizó este estudio predictivo transversal con adultos de 18 y 60 años atendidos en el Centro de Salud Primero de Julio del municipio de Mixco, Guatemala. Participaron 80 adultos, seleccionados por un muestreo aleatorio simple. El instrumento de recolección de datos estuvo conformado por tres secciones: información general de la persona, parámetros antropométricos y la encuesta de FINDRISC. Se generaron modelos lineales generalizados para identificar relaciones entre índice cintura talla (ICT), índice cintura cadera (ICC) y puntaje de la escala FINDRISC (Finnish Diabetes Risk Score). El 36.2% presentó riesgo de desarrollar DM2 a largo plazo; encontrándose un 21.2% en el nivel de riesgo alto y muy alto. Se comprobó que únicamente existe relación significativa entre el ICT y el puntaje de la escala de FINDRISC como determinante del riesgo de padecer DM2 a largo plazo. Se concluye que la implementación de la medición del ICT constituye una herramienta útil para identificar personas con riesgo de desarrollar DM2, siendo su aplicación sencilla, no invasiva, económica y de fácil acceso en los servicios de salud.

Type 2 diabetes mellitus (T2DM) is a health threat due to the complications derived from a late diagnosis, where timely identification is essential. This study aimed to establish the relationship between waist-height index (WHR), waist-hip index (WHR) and the FINDRISC (Finnish Diabetes Risk Score)scale as determinants of the risk of suffering from T2DM in the long term. A cross-sectional predictive study was carried out with a simple random sample of 80 adults between 18 and 60 years old treated at the Primero de Julio Health Center in Mixco, Guatemala. The data collection instrument was structured into three sections: general information, anthropometric parameters and the FINDRISC survey. Generalized linear models were generated to identify relationships between waist-height ratio (WHR), waist-hip ratio (WHR) and the FINDRISC scale score (Finish Diabetes Risk Score). The results shows that 36.2% of the participants were at risk of developing T2DM in the long term; 21.2% being at the high and very high risk level. It was found that there is only a significant relationship between the WHR and the FINDRISC scale score as a determinant of the risk of suffering from T2DM in the long term. The implementation of the waist height index measurement constitutes a useful tool to identify people at risk of developing T2DM, its application being simple, non-invasive, economical and easily accessible in health services.

Noble hosts: effects of internal parasites on the physiology of an intertidal brooding Sea-star / Huéspedes nobles: los efectos de parásitos internos en la fisiología de una estrella de mar incubadora del intermareal

Abstract Introduction: The endoparasite Dendrogaster argentinensis infects the intertidal brooder sea star Anasterias antarctica. This sea-star species is in the highest trophic level in the Beagle Channel. Objective: To study the effects of parasitism by D. argentinensis on the fitness and reproduction of A. antarctica. Methods: Adults from the brooder sea-star were collected from the rocky intertidal of Ensenada Zaratiegui bay (54°51' S & 68°29' W), Argentina. Eight seasonal samplings were performed (four seasons in two years) in the upper and low intertidal. During dissection, parasites were removed, and all organs were extracted and weighed separately. Results: Dendrogaster argentinensis prevalence was the highest for the region (20.4 %). Parasitized individuals were more frequent in the low intertidal in all seasons, with a higher difference in summer, where it is likely that the higher temperatures and strong winds could make the upper intertidal more challenging for a parasitized individual. Five parasitized individuals were castrated. Generally, the gonadal (GI) and somatic (pyloric caeca, PCI; stomach, SI; body wall, WI) indexes were lower in parasitized than non-parasitized individuals. Conclusions: Parasitism by D. argentinensis negatively affects A. antarctica condition. It affects reproduction because it reduces the GI, and can also produce castration. The parasite competes for the sea-stars' energetic resources, also decreasing the individual's capacity for feeding (reduced stomach) and growth (reduced body wall).

Resumen Introducción: El endoparásito Dendrogaster argentinensis infecta a la estrella de mar Anasterias antarctica, especie que se encuentra en el nivel trófico más alto del Canal Beagle. Objetivo: Estudiar los efectos del parasitismo de D. argentinensis en la condición fisiológica y reproducción de A. antarctica. Métodos: Adultos de la estrella de mar incubadora fueron recogidos del intermareal rocoso de la bahía Ensenada Zaratiegui (54°51' S & 68°29' W). Se realizaron ocho muestreos estacionales (cuatro temporadas en dos años) en el intermareal superior y bajo. Durante la disección, se removieron los parásitos, y todos los órganos, los cuales fueron pesados por separado. Resultados: La prevalencia de D. argentinensis fue la más alta de la región (20.4 %). Los individuos parasitados fueron más frecuentes en el intermareal bajo en todas las estaciones, siendo la mayor diferencia en verano, donde es probable que las temperaturas más altas y los fuertes vientos puedan hacer que el intermareal superior sea más desafiante para un individuo parasitado. Se observaron cinco individuos parasitados que estaban castrados. Generalmente, los índices gonadales (GI) y somáticos (ciego pilórico, estómago, y pared del cuerpo) fueron menores en los individuos parasitados que no parasitados. Conclusiones: El parasitismo de D. argentinensis afecta negativamente la condición fisiológica de A. antarctica. Afecta a la reproducción en términos de bajo GI y puede causar castración. El parásito compite por los recursos energéticos de las estrellas de mar, disminuyendo también la capacidad del individuo para alimentarse (reducción del estómago) y crecer (reducción de la pared del cuerpo).

Introducción: Entre las variables que afectan el riesgo de mortalidad relacionada (MRT) al trasplante alogénico de células progenitoras hematopoyéticas (TACPH) se incluyen las comorbilidades previas. Los índices de comorbilidad (IC) buscan mejorar la predicción de eventos combinando factores de riesgo independientes. Objetivos: 1) evaluar el uso de la versión breve y adaptada para niños, adolescentes y adultos jóvenes con enfermedad maligna del índice de comorbilidad específico para trasplante alogénico de células progenitoras hematopoyéticas (smyHCT-CI ); 2) evaluar el uso de los biomarcadores ferritina y albúmina en un índice de comorbilidad ampliado (smyHCT-CIa). Población y métodos: Diseño: cohorte retrospectiva. Periodo 2017- 2022. A cada p se le asignó nuevos puntajes utilizando el smyHCT-CI y el smyHCT-CIa. Los p se clasificaron en grupos de riesgo (GR) bajo (puntaje 0), intermedio (1-2) y alto (>3) con cada índice. Se comparó el n° de p asignado a cada GR grupo de riesgo y la MRT en cada grupo al usar el HCT-CI, el smyHCTCI y el smyHCT-CIa. Resultados: n 75. Frecuencia de p por GR según cada indicador (IC95): HCT-CI bajo 36 (25-47), intermedio 57 (56-69), alto 7 (1-12); smyHCT-CI: bajo 48 (37-59), intermedio 33 (23-44), alto 19 (10-27); smyHCT-CIa: bajo 43 (31-54), intermedio 36 (25-47), alto 21 (12-31). MRT por GR según indicador (IC95): HCT-CI: bajo 6,8 (14-28), intermedio 20,9 (9-33), alto 17,9 (0-55); smyHCT-CIa bajo 12,5 (1-24), intermedio 18,5 (4-33), alto 31,2 (9-54). Conclusión: El smyHCT-CI permitió identificar mejor los pacientes con mayor comorbilidad y riesgo de MRT. La ferritina resultó un biomarcador útil en la estimación del riesgo de MRT (AU)

Introduction: Variables affecting allogeneic hematopoietic stem cell transplantation (HCT) related mortality risk (TMR) include prior comorbidities. Comorbidity indices (CI) aim to improve event prediction by combining independent risk factors. Objectives: 1) to evaluate the use of the brief and adapted version of the HCT-specific comorbidity index for children, adolescents and young adults with malignancies (ymHCT-CI); 2) to evaluate the use of the biomarkers ferritin and albumin in an expanded comorbidity index (expanded ymHCT-CI). Population and methods: Design: retrospective cohort. Period 2017- 2022. Each patient was assigned new scores using the ymHCTCI and expanded ymHCT-CI. The p were classified into low (score 0), intermediate (1-2) and high (>3) risk groups (RG) with each index. The number of patients assigned to each RG and the TMR in each group were compared using the HCTCI, the ymHCT-CI, and the expanded ymHCT-CI. Results: n 75. Frequency of patients per RG according to each indicator (95%CI): HCT-CI low 36 (25-47), intermediate 57 (56-69), high 7 (1-12); ymHCT-CI: low 48 (37-59), intermediate 33 (23-44), high 19 (10-27); expanded ymHCT-CI: low 43 (31-54), intermediate 36 (25-47), high 21 (12-31). TMR by RG according to indicator (95%CI): HCT-CI: low 6.8 (14-28), intermediate 20.9 (9-33), high 17.9 (0-55); expanded ymHCT-CI low 12.5 (1-24), intermediate 18.5 (4-33), high 31.2 (9-54). Conclusion: ymHCT-CI allowed better identification of patients with higher comorbidity and risk of TMR. Ferritin proved to be a useful biomarker to estimate TMR risk (AU)

Este estudio transversal se desarrolló con una muestra de 50 estudiantes de odontología de 19 a 34 años de edad, 58% mujeres y 42% hombres. Se recogieron muestras de saliva entera sin estimular en la mañana (6:30-7:30 a.m.) y en la tarde (4:00-6:00 p.m.). Los valores de AAs se determinaron mediante método cinético y se expresaron como media ± desviación estándar. Se realizaron análisis descriptivo de datos, prueba de chi-cuadrado, prueba de correlación de Pearson y prueba t de muestras pareadas. Resultados. El IMC promedio fue de 23,85 ± 3,30 kg/m2, 66% de los participantes presentó peso normal (IMC ≤ 25 kg/m2). Los niveles de AAs por la tarde (282,74 ± 59,60 U/ml) fueron mayores a los de la mañana (190,84 ± 61,80 U/ml), (t = 16,51, p < 0,0001). Los hombres mostraron niveles de AAs más altos que las mujeres (p < 0,0001). La edad no mostró asociación con los niveles de AAs. Los valores de IMC y AAs presentaron una correlación positiva (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusión. El nivel de actividad de AAs se puede utilizar como posible biomarcador para evaluar el IMC en relación con el sexo, especialmente en los adultos jóvenes.

Objective. To determine the presence and direction of the relationship between salivary alpha-amylase (sAA), age, sex, and body mass index (BMI) in young adults. Methods. This cross-sectional study was developed with a sample of 50 dental students from 19 to 34 years of age, 58% women and 42% men. Unstimulated whole saliva samples were collected in the morning (6:30-7:30 a.m.) and in the afternoon (4:00-6:00 p.m.). sAA values were determined by the kinetic method and expressed as mean ± standard deviation. Descriptive data analysis, chi-square test, Pearson correlation test, and paired samples t-test were made. Results. Mean BMI was 23.85 ± 3.30 kg/m2, 66% of the participants presented normal weight (BMI ≤ 25 kg/m2). Levels of sAA in the afternoon (282.74 ± 59.60 U/ml) were higher than those in the morning (190.84 ± 61.80 U/ml), (t = 16.51, p < 0, 0001). Men showed higher levels of sAA than women (p < 0.0001). Age did not show an association with sAA levels. BMI and AAs values presented a positive correlation (AM: r = 0,35, p = 0,0121; PM: r = 0,40, p = 0,0036). Conclusions. AAs activity level can be used as a potential biomarker to assess BMI in relation to sex, especially in young adults.

The Relationship of Anatomical Localizations of Hiatal Clamp and Oesophagogastric Junction with Body Mass Index / Relación entre las Localizaciones Anatómicas de la Pinza Hiatal y la Unión Esofagogástrica con el Índice de Masa Corporal

SUMMARY: In our study, we aimed to reveal the relationship between the anatomical localizations measured and the Body Mass Index (BMI) in patients scheduled for upper gastrointestinal endoscopy. In this study, anatomical localizations of the hiatal clamp and oesophagogastric junction in 189 female and 137 male patients who applied to the hospital with different gastrointestinal system complaints and underwent esophagogastroduodenoscopy (EGD) were investigated depending on BMI. In addition, the data were compared with the patients' complaints before EGD and the diagnoses they received after EGD. SPSS Statistics 22 (IBM Corp. Turkey) program was used for statistical analysis and p0.05). On the other hand, it was determined that the hiatal clamp distance and the distance of the oesophagogastric junction increased as the height and weight increased (p38. As a result of the study, it can be said that BMI values, hiatal clamp distance and oesophagogastric junction localizations may change in relation to height and weight.

En este estudio, buscamos revelar la relación entre las localizaciones anatómicas y el Índice de Masa Corporal (IMC) en pacientes programados para endoscopía digestiva alta. Se investigaron las localizaciones anatómicas de la pinza hiatal y la unión esofagogástrica en 189 mujeres y 137 hombres que acudieron al hospital con diferentes problemas del sistema gastrointestinal los cuales fueron sometetidos a una esofagogastro- duodenoscopia (EGD) dependiendo del IMC. Además, los datos se compararon con las quejas de los pacientes antes de la EGD y los diagnósticos que recibieron después de la EGD. Se utilizó el programa SPSS Statistics 22 (IBM Corp. Turquía) para el análisis estadístico y el valor de p0,05). Por otro lado, se determinó que la distancia de la pinza hiatal y la unión esofagogástrica aumentaba con la altura y el peso corporal (p38. Como resultado del estudio, se puede decir que los valores de IMC, la distancia de pinzamiento hiatal y las localizaciones de la unión esofagogástrica pueden cambiar en relación con la altura y el peso.

The data were obtained from the National Office of Statistics and Information statistical yearbooks, of the National and Provincial Public Health Ministry Directorate of Statistics. Results: the adolescent fertility rate presents slight oscillations, going from 46.7 children per woman in 2012 to 45.4 in 2021. The age group with the highest fertility is 20-24 years old, the average age is in the age group 25-29 years old and the municipalities with the greatest weight in total fertility are Abreus and Aguada de Pasajeros. Conclusions: the adolescent fertility rate shows resistance to decline, a behavior that demonstrates the need to emphasize sexual education policies and strategies for the most vulnerable age groups within the reproductive group.

Estudio etnobotánico de la flora medicinal de la provincia de Trujillo, Perú / Ethnobotanical study of the medicinal flora of the province of Trujillo, Peru

Trujillo, one of the main provinces of Peru, is home to a multicultural population, coming from the Coast, Sierra and Selva; of different ideologies, cultures, and ancestral knowledge about the correct use of medicinal flora. In this sense and in an effort to rescue this ancestral knowledge, the ethnobotanical study of the medicinal flora of the province of Trujillo was carried out. For which 96 semi - structured interviews were applied, using the "snowball" technique; followed by the collection, taxonomic determination and calculation of ethnobotanical indices: Use Value Index (IVU) and Informant Consensus Factor Index (FCI). It is concluded that the inhabitants of Trujillo make use of 102 species of medicinal flora, distributed in 95 genera and 46 families for the treatment and/or cure of 62 diseases. Of the total species, 24 turned out to be the most important (according to their IVU) for the cure of diseases of the Trujillo po pulation.

Trujillo, una de las principales provincias de Perú, alberga una población pluricultural, procedente de la Costa, Sierra y Selv a; de distintas ideologías, culturas, y saberes ancestrales sobre el correcto uso de la flora medicinal.

Testes de Triagem Prevendo Metástase de Câncer na Etiologia do Derrame Pericárdico: HALP Score e PNI / Screening Tests Predicting Cancer Metastasis in the Etiology of Pericardial Effusion: HALP Score and PNI

Resumo Fundamento: A triagem do câncer é absolutamente necessária em pacientes com derrame pericárdico, pois o câncer é uma das doenças mais graves em sua etiologia. Estudos anteriores indicaram que o índice de inflamação imunológica sistêmica (IIS), o índice prognóstico nutricional (PNI) e o escore de hemoglobina, albumina, linfócitos e plaquetas (HALP) podem ser escores relacionados ao câncer. Objetivos: Este estudo foi iniciado considerando que esses sistemas de pontuação poderiam prever o câncer na etiologia de pacientes com derrame pericárdico. Métodos: Os pacientes submetidos à pericardiocentese entre 2006 e 2022 foram analisados retrospectivamente. A pericardiocentese foi realizada em um total de 283 pacientes com derrame pericárdico ou tamponamento cardíaco de moderado a grande no período especificado. Os índices de HALP, PNI e IIS foram calculados do sangue venoso periférico retirado antes do procedimento de pericardiocentese. O nível de significância estatística foi aceito em p<0,05. Resultados: O escore HALP foi de 0,173 (0,125-0,175) em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi de 0,32 (0,20-0,49; p<0,001). O escore de PNI foi de 33,1±5,6 em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi 39,8±4,8 (p<0,001). Conclusão: Os escores HALP e PNI são testes de triagem de câncer fáceis e rápidos que podem prever metástases de câncer na etiologia de pacientes com derrame pericárdico.

Abstract Background: Cancer screening is absolutely necessary in patients with pericardial effusion, given that cancer is one of the most serious diseases in the etiology of pericardial effusion. In previous studies, it was stated that the systemic immune-inflammation index (SII); the prognostic nutrition index (PNI); and the hemoglobin, albumin, lymphocyte, platelet (HALP) score can produce scores related to cancer. Objectives: This study began considering that these scoring systems could predict cancer in the etiology of patients with pericardial effusion. Methods: This study produced a retrospective analysis of patients who underwent pericardiocentesis between 2006 and 2022. Pericardiocentesis was performed in a total of 283 patients with moderate-to-large pericardial effusion or pericardial tamponade within the specified period. HALP, PNI, and SII scores were calculated according to the peripheral venous blood taken before the pericardiocentesis procedure. The statistical significance level was set at p<0.05. Results: The HALP score proved to be 0.173 (0.125-0.175) in cancer patients and 0.32 (0.20-0.49) in non-cancer patients (p<0.001). The PNI score proved to be 33.1±5.6 in cancer patients and 39.8±4.8 in non-cancer patients (p<0.001). Conclusion: The HALP score and PNI proved to be easy and fast cancer screening tests that can predict cancer metastasis in the etiology of patients with pericardial effusion.

Aplicabilidad del índice de fragilidad hepática en pacientes cirróticos evaluados para trasplante / Applicability of the liver frailty index in cirrhotic patients evaluated for transplantation

Introducción. En las últimas décadas se han desarrollado diferentes scores y modelos para predecir el pronóstico en pacientes con enfermedad hepática crónica avanzada. Los más reconocidos y utilizados son el sistema de estadificación de Child-Pugh (CP) y el score de MELD, pero estos carecen de herramientas para evaluar objetivamente otros factores pronósticos. Por este motivo, se ha incorporado el concepto de fragilidad a la hepatología clínica. El objetivo de este artículo es examinar la aplicabilidad del índice de fragilidad hepática (IFH) en pacientes con cirrosis evaluados para trasplante hepático en Uruguay. Metodología. Estudio observacional, descriptivo y retrospectivo en el Servicio de Enfermedades Hepáticas del Hospital Central de las Fuerzas Armadas (HCFFAA) de enero de 2018 a diciembre de 2021. Resultados. Se evaluaron un total de 78 pacientes, excluyéndose 19 de estos, culminando con una muestra final de 59 pacientes. La edad media fue de 52 años, siendo el 66 % hombres. La principal etiología de la cirrosis fue la alcohólica, y la comorbilidad más frecuente fue el sobrepeso/obesidad (66 %). La media de IFH fue de 4,03 ± 0,45. El 90 % de los pacientes eran prefrágiles, el 10 % frágiles y ningún paciente fue clasificado como no frágil. El 76 % presentaba un estadio avanzado de la enfermedad al momento de la evaluación 42 % CP estadio B, 34 % CP C, 24 % CP A, con una media de MELD-Na de 17,8 ± 7,6. El 17 % tuvo complicaciones infecciosas. La mortalidad global (n=78) fue del 12 %, y la de los pacientes con IFH calculado fue del 22 %. Conclusiones. El cálculo del IFH es realizable en cirróticos como herramienta objetiva que brinda una mirada integral del paciente. A mayor severidad de la cirrosis, mayor es el IFH. Sin embargo, este índice no parece ser un predictor de la eventual realización del trasplante hepático, ni de muerte en lista de espera en nuestros pacientes.

Introduction. In recent decades, several scores and models have been proposed to predict prognosis in patients with advanced chronic liver disease. The most recognized and used are the Child-Pugh (CP) and the Model for End-stage Liver Disease (MELD) scores, but they lack tools to objectively evaluate other prognostic factors. For this reason, the concept of fragility has been incorporated into clinical hepatology. The objective of this study was to evaluate the applicability of the liver frailty index (LFI) in patients with cirrhosis evaluated for liver transplantation in Uruguay. Methodology. Observational, descriptive and retrospective study at the Hospital Central de las Fuerzas Armadas (HCFFAA) Liver Disease Service from January 2018 to December 2021. Results. A total of 78 patients were evaluated, 19 were excluded, culminating in a final sample of 59 patients. The mean age was 52 years, with 66% being men. The main etiology of cirrhosis was alcoholic and the most frequent comorbidity was overweight/obesity (66%). The mean LFI was 4.03 ± 0.45. 90% of patients were pre-fragile, 10% were fragile, and no patient was classified as non-fragile. 76% had an advanced stage of the disease at the time of evaluation: 42% CP stage B, 34% CP C, 24% CP A, with a mean MELD-Na of 17.8 ± 7.6. 17% had infectious complications. Overall mortality (n=78) was 12%, and that of patients with calculated LFI was 22%. Conclusions. The LFI can be calculated in cirrhotic patients, and it is an objective tool that provides a comprehensive view of the patient. LFI depends on the severity of the cirrhosis. However, this index is not a predictor of liver transplantation or death on the waiting list in our patients.

Association between childhood anthropometric indicators and bone mineral density in adulthood / Associação entre indicadores antropométricos na infância e densidade mineral óssea na idade adulta

ABSTRACT Objective: This study aimed to verify the association between childhood anthropometric indicators and areal bone mineral density (aBMD) in adulthood. Methods: Repeated measures of 137 subjects (68 females) were obtained in childhood (9.2±1.5 years of age) and adulthood (22.3±1.7 years of age). aBMD (g/cm2) was assessed for whole body, lumbar spine, upper and lower limbs, and femoral neck in adulthood using dual-energy X-ray absorptiometry. Anthropometric measurements of body weight (BW), height, triceps and subscapular skinfolds were obtained in childhood. The anthropometric indicators used were BW, body mass index (BMI), and sum of skinfolds (ΣSF). Simple linear regression was used to assess the association between childhood anthropometric indicators and aBMD in adulthood, controlled by chronological age and stratified by sex, with 5% statistical significance. Results: In females, multiple associations were observed between anthropometric indicators and aBMD, with higher coefficients for BMI (β=0.020; R2=0.20; p<0.01 for right femoral neck to β=0.008; R2=0.16; p<0.01 for upper limbs), followed by BW (β=0.003; R2=0.21; p<0.01 for upper limbs to β=0.008; R2=0.20; p<0.01 for right femoral neck) and ΣSF (β=0.001; R2=0.06; p<0.01 for upper limbs to β=0.005; R2=0.12; p<0.01 for right femoral neck). In males, associations were observed only for the lumbar spine region (β=0.016; R2=0.09 for BMI to β=0.004; R2=0.06; p<0.01 for ΣSF). Conclusions: Anthropometric indicators of childhood proved to be sensitive predictors of aBMD in adulthood, especially in females. BMI indicated a greater association with aBMD in both sexes.

RESUMO Objetivo: O objetivo do estudo foi verificar a associação entre os indicadores antropométricos da infância com a área da densidade mineral óssea (aDMO) na idade adulta. Métodos: Medidas repetidas de 137 sujeitos (68 do sexo feminino) foram obtidos na infância (9,2±1,5 anos de idade) e idade adulta (22,3±1,7 anos de idade). A aDMO (g/cm2) foi avaliada para todo o corpo, coluna lombar, membros superiores e inferiores e colo do fêmur na idade adulta usando a absorciometria radiológica de dupla energia (DXA). Medidas antropométricas de peso corporal, estatura e dobras cutâneas das regiões tricipital e subescapular foram obtidas na infância. Os indicadores antropométricos utilizados para as análises foram o peso corporal (PC), o índice de massa corporal (IMC) e o somatório de dobras cutâneas (ΣDC). Regressão linear simples controlada pela idade e estratificada por sexo foi empregada para avaliar a associação entre os indicadores antropométricos do período da infância na aDMO na idade adulta, com significância estatística de 5%. Resultados: No sexo feminino, múltiplas associações foram observadas entre os indicadores antropométricos e a aDMO, com maiores coeficientes para IMC (β=0,020; R2=0,20; p<0.01 para colo do fêmur direito a β=0,008; R2=0,16; p<0,01 para membros superiores), seguido da PC (β=0,003; r2=0,21; p<0,01 para membros superiores a β=0,008; r2=0,20; p<0,01 para colo do fêmur direito) e ΣDC (β=0,001; R2=0,06; p<0,01 para membros superiores a β=0,005; R2=0,12; p<0,01 para colo do fêmur direito). No sexo masculino, associações ocorreram apenas na região da coluna (β=0,016; R2=0,09 para IMC a β=0,004; R2=0,06; p<0,01 para ΣDC). Conclusões: Indicadores antropométricos da infância mostraram ser sensíveis preditores da aDMO na idade adulta, especialmente no sexo feminino. O IMC indicou maior associação com a aDMO em ambos os sexos.

Características sociodemográficas associadas ao baixo peso e ao excesso de peso em adultos com 50 anos ou mais (ELSI-Brasil): diferenças entre sexos / Sociodemographic characteristics associated with underweight and overweight in adults aged 50 years and over (ELSI-Brasil): differences between sexes / Características sociodemográficas asociadas al bajo peso y al sobrepeso en adultos de 50 años o más (ELSI-Brasil): diferencias entre sexos

Os objetivos foram descrever a prevalência de baixo peso e excesso de peso, avaliados pelo índice de massa corporal (IMC), estratificada por sexo e faixa etária, e analisar as características sociodemográficas associadas ao IMC em mulheres e homens mais velhos. Trata-se de uma análise transversal de 8.974 participantes com ≥ 50 anos da linha de base do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil, 2015-16). O IMC foi classificado em baixo peso, eutrofia e excesso de peso de acordo com a idade do participante. Foi utilizado modelo de regressão logística multinominal, considerando-se as características sociodemográficas de mulheres e homens. Os resultados evidenciaram maior prevalência de excesso de peso nas mulheres em comparação aos homens (64,1% vs. 57,3%). Em ambos os sexos, a prevalência de baixo peso foi maior nos mais longevos, enquanto que o excesso de peso foi menor. Nas mulheres, a chance de baixo peso foi maior do que a chance de eutrofia naquelas solteiras/viúvas/divorciadas (OR = 1,95; IC95%: 1,42-2,66) e nas residentes na área rural (OR = 1,58; IC95%: 1,01-2,49), ao passo que a chance de excesso de peso foi menor do que a chance de eutrofia nas residentes na área rural (OR = 0,78; IC95%: 0,62-0,97) e em todas as macrorregiões geográficas relativas à Região Sul. Para os homens, a chance de excesso de peso foi menor do que a chance de eutrofia entre solteiros/viúvos/divorciados (OR = 0,58; IC95%: 0,48-0,69). Os mais ricos apresentaram menor chance de baixo peso (OR = 0,59; IC95%: 0,38-0,90), bem como maior chance de excesso de peso (OR = 1,52; IC95%: 1,20-1,92). Em conclusão, as características sociodemográficas associadas ao IMC diferiram entre os sexos.

The objective were to describe the prevalence of underweight and overweight, assessed by body mass index (BMI), stratified by sex and age group, and to analyze the sociodemographic characteristics associated with BMI in older women and men. This is a cross-sectional analysis of 8,974 participants aged ≥ 50 years from the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brasil, 2015-2016). BMI was classified as underweight, eutrophy, and overweight according to the participant's age. A multinomial logistic regression model was used, considering the sociodemographic characteristics of women and men. The results showed a higher prevalence of overweight in women compared to men (64.1% vs. 57.3%). In both sexes, the prevalence of underweight was higher in the longest-lived individuals, while overweight was lower. In women, the chance of underweight was higher than the chance of eutrophy in those who were single/widowed/divorced (OR = 1.95; 95%CI: 1.42-2.66) and in those living in rural areas (OR = 1.58; 95%CI: 1.01-2.49), while the chance of being overweight was lower than the chance of being eutrophy in those living in rural areas (OR = 0.78; 95%CI: 0.62-0.97) and in all geographic macro-regions related to the South Region. For men, the chance of being overweight was lower than the chance of being eutrophy among single/widowed/divorced individuals (OR = 0.58; 95%CI: 0.48-0.69). The richest had a lower chance of being underweight (OR = 0.59; 95%CI: 0.38-0.90), as well as a higher chance of being overweight (OR = 1.52; 95%CI: 1.20-1.92). In conclusion, the sociodemographic characteristics associated with BMI differed between the sexes.

Los objetivos fueron describir la prevalencia de bajo peso y sobrepeso, evaluados a través del índice de masa corporal (IMC), estratificada por sexo y grupo de edad, y analizar las características sociodemográficas asociadas al IMC en mujeres y hombres mayores. Se trata de un análisis transversal de 8.974 participantes con ≥ 50 años de la línea de base del Estudio Longitudinal Brasileño sobre el Envejecimiento (ELSI-Brasil, 2015-2016). Se clasificó el IMC en bajo peso, eutrofia y sobrepeso conforme la edad del participante. Se utilizó el modelo de regresión logística multinomial, teniendo en cuenta las características sociodemográficas de mujeres y hombres. Los resultados evidenciaron una prevalencia más alta de sobrepeso en las mujeres en comparación con los hombres (64,1% vs. 57,3%). En ambos sexos, la prevalencia de bajo peso fue más alta en los grupos de mayor edad, mientras que la prevalencia del sobrepeso fue menor. La chance de bajo peso fue más alta que la chance de eutrofia en las mujeres solteras/viudas/divorciadas (OR = 1,95; IC95%: 1,42-2,66) y en las que viven en el área rural (OR = 1,58; IC95%: 1,01-2,49), mientras que la chance de sobrepeso fue menor que la chance de eutrofia en las que viven en el área rural (OR = 0,78; IC95%: 0,62-0,97) y en todas las macrorregiones geográficas relacionadas a la región Sur. La chance de sobrepeso fue menor que la chance de eutrofia entre los hombres solteros/viudos/divorciados (OR = 0,58; IC95%: 0,48-0,69). Los más ricos presentaron una chance menor de bajo peso (OR = 0,59; IC95%: 0,38-0,90), así como una chance más alta de sobrepeso (OR = 1,52; IC95%: 1,20-1,92). En conclusión, las características sociodemográficas asociadas al IMC difirieron entre los sexos.

Association between sleep duration and latency, nocturnal awakenings, and body mass index among infants / Associação entre duração e latência do sono, despertares noturnos e índice de massa corporal de lactentes

ABSTRACT Objective: To investigate the association between sleep duration, nocturnal awakenings, and sleep latency with body mass index (BMI) at six and 12 months of age. Methods: 179 children from a birth cohort were enrolled. At six and 12 months of age, anthropometric data were obtained using standardized techniques and infants' mothers answered the Brief Infant Sleep Questionnaire for sleep data. The association of BMI with the independent variables (sleep duration, latency, and nocturnal awakenings) was assessed by linear regression models. Analyses were adjusted for potential confounders and a p-value<0.05 was adopted to define statistical significance. Results: For each additional hour of sleep duration, BMI was reduced by 0.15 kg/m² (95% confidence interval [CI] -0.28; -0.01; p=0.03) and each additional minute of sleep latency increased BMI by 0.01 kg/m² (95%CI -0.00; 0.03; p=0.02). These associations were independent of gestational age, child sex, birth weight, duration of exclusive breastfeeding, smoking during pregnancy, and mother's BMI, education, and marital status. Nocturnal awakenings showed no association with the outcome. Conclusions: Our findings suggest that sleep duration and sleep latency time are associated with BMI in the first year of life. Insights into the influence of sleep early in life on weight status may be helpful to complement future nutritional recommendations and prevent and treat obesity.

RESUMO Objetivo: Investigar a associação entre duração do sono, despertares noturnos e latência do sono com o índice de massa corporal (IMC) aos seis e 12 meses de idade. Métodos: foram incluídas 179 crianças de uma coorte de nascimentos. Aos seis e 12 meses de idade, dados antropométricos foram obtidos por meio de técnicas padronizadas e as mães dos lactentes responderam ao Brief Infant Sleep Questionnaire para dados do sono. A associação do IMC com as variáveis independentes (duração do sono, latência e despertares noturnos) foi avaliada por modelos de regressão linear. As análises foram ajustadas para potenciais fatores de confusão e o p-valor<0,05 foi adotado para definir a significância estatística. Resultados: Para cada hora adicional de duração do sono, o IMC foi reduzido em 0,15 kg/m² (intervalo de confiança [IC]95% -0,28; -0,01; p=0,03) e cada minuto adicional no tempo de latência resultou em aumento de 0,01 kg/m² (IC95% -0,00; 0,03; p=0,02) no IMC. Essas associações foram independentes da idade gestacional, sexo da criança, peso ao nascer, duração do aleitamento materno exclusivo, tabagismo durante a gravidez e IMC, escolaridade e estado civil da mãe. Os despertares noturnos não apresentaram associação com o desfecho. Conclusões: Nossos achados sugerem que a duração e a latência do sono estão associadas ao IMC no primeiro ano de vida. Informações sobre a influência do sono no início da vida sobre o status do peso podem ser úteis para complementar futuras recomendações nutricionais e prevenir e tratar a obesidade.

The bioprotective role of irradiated hibiscus against harmful effects of using repeatedly frying edible oil

Abstract Repeatedly frying process of dietary edible oil has a potential role in the generation of free radicals. Therefore, questions have always been raised as to whether, there is an efficient and economical method to reduce the harmful effects of repeated use of frying edible oil. Since hibiscus has been stated to have a wide variety of therapeutic effects, it was important to investigate its properties against harmful effects of free radicals. The current study aspires to find out whether irradiated powder of hibiscus has a protective role against adverse effects of repeated use of frying edible oil. Thirty-five adult male albino rats were equally assigned into five groups. First groupG1 was fed with normal diet as control group, meanwhile, groupG2 the diet mixed with fresh oil, G3 diet mixed with repeatedly frying oil only, G4 diet mixed with frying oil treated with hibiscus and G5 diet mixed with frying oil treated with irradiated hibiscus. Feeding duration was six weeks. Fatty acid analyses of oil as well as peroxide values were determined. Blood and liver samples were collected for biochemical analyses as well as histological study. Repeatedly heated cooked oil has significant increases in peroxide value, acid value, free fatty acid and both conjugated diene and triene compared with repeatedly frying oil treated with hibiscus. Also there are significant increases in cholesterol and triglyceride and impaired in liver functions in G3compared with others. In addition, relative to the hibiscus groups, there is a substantial reduction in oxygen consumption in G3. Both hibiscus as well as irradiated hibiscus attract attention in order to play a vital and economical role against harmful effects of frequent use of frying edible oil on some biological functions but, irradiated hibiscus was more effective.

Resumo O processo de fritura repetida de óleo comestível da dieta tem papel potencial na geração de radicais livres que podem ter efeitos prejudiciais em algumas funções biológicas. Portanto, sempre se questionou se existe uma maneira eficiente e econômica de prevenir ou pelo menos reduzir os efeitos nocivos do uso repetido de óleo comestível para fritar. Como o hibisco tem ampla variedade de efeitos terapêuticos, foi importante investigar suas propriedades como agente antioxidante contra os efeitos nocivos dos radicais livres. O presente estudo pretende descobrir se o pó irradiado de hibisco tem papel protetor contra os efeitos adversos do uso repetido de óleo comestível para fritar. Trinta e cinco ratos albinos machos adultos foram divididos igualmente em cinco grupos. O primeiro grupo G1 foi alimentado com dieta normal como grupo controle, enquanto o grupo G2 dieta misturada com óleo fresco, dieta G3 misturada com óleo de fritura repetida, dieta G4 misturada com óleo de fritura tratada com hibisco e dieta G5 misturada com óleo de fritura tratada com hibisco irradiado. A duração da alimentação foi de seis semanas. Foram determinadas as análises de ácidos graxos de óleo, bem como os valores de peróxidos. Amostras de sangue e fígado foram coletadas para análises bioquímicas e estudo histológico. O óleo cozido repetidamente aquecido tem aumentos significativos no valor de peróxido, valor de ácido, ácido graxo livre e dieno e trieno conjugados em comparação com óleo de fritura repetidamente tratado com hibisco. Também há aumentos significativos no colesterol e triglicérides e comprometimento das funções hepáticas no G3 em comparação com outros. Além disso, em relação aos grupos de hibiscos, há uma redução substancial no consumo de oxigênio no G3. Tanto o hibisco como o hibisco irradiado chamam atenção por desempenhar papel vital e econômico contra os efeitos nocivos do uso frequente de óleo comestível para fritar em algumas funções biológicas, mas o hibisco irradiado foi mais eficaz.

Assessment of particulate matter (PM) in ambient air of different settings and its associated health risk in Haripur city, Pakistan

Abstract Particulate matter (PM) is a major air pollutant causing serious health problems. The aim of the present study was to find out concentration of PM in ambient air and its associated health risk in Haripur city, Pakistan. Twenty-three samples were taken at various educational institutes, hospitals, recreational areas and industries in Haripur city. Concentration of PM2.5 (µg/m3) and PM10 (µg/m3) was measured with Youngteng YT-HPC 3000A portable PM counter. The results revealed that values of both PM2.5 and PM10 were above the permissible limits (35 µg/m3 for PM2.5 and 150 µg/m3 for PM10) set by Environmental Protection Agency Pakistan (Pak-EPA) in all the educational institutes, hospitals, recreational areas and industries investigated. Furthermore, significant (p 0.05) variation was found in the concentration of both PM2.5 and PM10 in all the educational institutes, hospitals, recreational areas, and industries studied. The concentration of PM2.5 was positively correlated with the concentration of PM10 in all the sampling sites. Therefore, from 1-14 scale standard of health index, the values of PM2.5 and PM10 exhibited that the ambient air quality of Haripur city Pakistan is under high risk. If the regulatory authorities such as Environmental Protection Agency, Health Department and Local Government monitor PM pollution in different settings of Haripur city, then a decrease can be possible in the pollution level. The remedies that can be taken to overcome the problem of ambient air pollution such as PM are plantation of trees at the sites where there are higher levels of air pollutants and use of masks on personal protection basis along with implementation of pollution control system in industries of Hattar Industrial Estate Haripur city, Pakistan.

Resumo O material particulado (MP) é um importante poluente do ar que causa sérios problemas de saúde. O objetivo do presente estudo foi descobrir a concentração de MP no ar ambiente e sua associação com o risco à saúde na cidade de Haripur, Paquistão. Vinte e três amostras foram coletadas em várias instituições de ensino, hospitais, áreas recreativas e indústrias na cidade de Haripur. A concentração de MP2,5 (µg/m3) e MP10 (µg/m3) foi medida por meio do contador de MP portátil Youngteng YT-HPC 3000A. Os resultados revelaram que os valores de MP2,5 e MP10 estavam acima dos limites permitidos (35 µg/m3 para MP2,5 e 150 µg/m3 para MP10) estabelecidos pela Agência de Proteção Ambiental do Paquistão (Pak-EPA) em todas as instituições de ensino, hospitais, áreas recreativas e indústrias investigadas. Além disso, foi encontrada variação significativa (p 0,05) na concentração de MP2,5 e MP10 em todos os locais estudados. A concentração de MP2,5 correlacionou-se positivamente com a concentração de MP10 em todos os locais de amostragem. Portanto, a partir da escala padrão 1-14 do índice de saúde, os valores de MP2,5 e MP10 mostraram que a qualidade do ar ambiente na cidade de Haripur, Paquistão, está sob alto risco. Se as autoridades reguladoras, como a Pak-EPA, o Departamento de Saúde e o governo local, monitorarem a poluição por MP em diferentes configurações da cidade de Haripur, pode ser que haja uma diminuição no nível de poluição. As medidas que podem ser tomadas para superar o problema da poluição do ar ambiente, como o MP, são o plantio de árvores nos locais onde há maiores níveis de poluentes atmosféricos, o uso de máscaras e a implantação de sistema de controle de poluição nas propriedades industriais de Hattar, na cidade Haripur, Paquistão.

Antiulcerogenic and antioxidant activities of Plantago ovata ethanolic extract in rats

Abstract This study aimed to determine the antiulcerogenic and antioxidant activities of Psyllium (Plantago ovata Forssk) seed ethanolic extract in rats. We assessed the antioxidant potential using free radical scavenging on DPPH, -carotene bleaching activity, ferric reducing power, and hydroxyl radical scavenging activity. In the antiulcerogenic study, pre-treatment with Plantago ovata seeds ethanolic extract (POE) (400 mg/kg b.wt) significantly protected against ethanol-induced gastric ulcer in rats by decreasing the ulcer index value and preserving the integrity of the gastric mucosa. The oxidative stress status in the stomach tissues showed a significant increase in the antioxidant enzyme levels of superoxide dismutase, catalase, and glutathione peroxidase with a significant decrease in lipid peroxidation during pre-treatment with POE. In conclusion, the POE protects against gastric ulcer due to its antioxidant potential and presence of bioactive molecules.

Resumo O presente estudo teve como objetivo determinar as atividades antiulcerogênica e antioxidante das sementes de Psyllium (Plantago ovata Forssk) em ratos. O potencial antioxidante foi avaliado utilizando o método do sequestro do radical livre DPPH, autooxidação do -caroteno, poder redutor de ferro e atividade de sequestro do radical hidroxila. No estudo antiulcerogênico, o pré-tratamento com o extrato etanólico das sementes de Plantago ovata (POE) (400 mg/Kg b.wt) reduziu a úlcera gástrica induzida pelo etanol em ratos, diminuindo o valor do índice de úlcera e preservando a integridade da mucosa gástrica. O estudo do estresse oxidativo nos tecidos estomacais mostrou um aumento significativo dos níveis das enzimas antioxidantes superóxido dismutase, catalase e glutationa peroxidase, com uma diminuição significativa da peroxidação lipídica enquanto pré-tratamento com POE. Em conclusão, o POE protege contra úlcera gástrica devido aos seus potenciais antioxidantes e à presença de moléculas bioativas.
