Caracterización de la conducta suicida en población general de la Región de Coquimbo (Chile) entre 2018 y 2020 / Characterization of suicidal behavior in Coquimbo, Chile, between 2018 and 2020

Introducción La conducta suicida es un problema de salud pública mundial. La Organización Mundial de la Salud estimó en 700 000 los fallecimientos por suicidio para el año 2021. Objetivo El propósito fue estimar la prevalencia de la conducta suicida y describir sus factores relacionados en la Región de Coquimbo, Chile, entre los años 2018 y 2020. Métodos Se analizaron 2190 notificaciones por intentos suicidas del sistema de vigilancia epidemiológica regional, que correspondieron a 1781 personas; junto con 217 informes de personas fallecidas por suicidio del Servicio Médico Legal. Resultados La tasa global de suicidio para la región en el período fue de 9,79 fallecimientos por 100 000 habitantes. Se estandarizaron las tasas del año 2018 según la información disponible, con método directo para la tasa regional (9,55 por 100 000 habitantes) e indirecto para las comunas. Las comunas rurales presentaron mayores tasas que las urbanas. Las mujeres mostraron mayor riesgo de intentos (: 1,28; intervalo de confianza 95%: de 1,23 a 1,33) y menor riesgo de suicidio (0,086; de 0,06 a 0,13) que los hombres. Las personas jóvenes presentaron mayor riesgo de intentos y menor riesgo de suicidio, comparado con personas mayores. Destaca el aumento de la tasa de suicidio en personas mayores (de 70 a 79 años) durante el año 2020. El nivel educacional básico es una variable de riesgo para suicidio (2,21; de 1,15 a 4,23), comparado con educación universitaria. Los intentos de suicidio previos y patología psiquiátrica son factores de riesgo. Conclusiones La prevalencia de suicidio y los factores relacionados son similares a lo reportado en otros estudios e informes nacionales, destacando la ruralidad y mayor riesgo en varones de edad adulta avanzada. A diferencia de los suicidios, los intentos son más frecuentes en mujeres y personas jóvenes. Antecedentes de problemas de salud mental, intentos previos y violencia en la familia son factores de riesgo para ambas conductas. Conocer el comportamiento de la conducta suicida en la población es fundamental para su prevención.

Introduction Suicidal behavior is a public health problem worldwide. The World Health Organization estimated 700 000 deaths for the year 2021. Objective This study aimed to estimate the prevalence of suicidal behavior and describe its related factors in the Coquimbo Region, Chile, between 2018 and 2020. Methods 2190 suicide attempt notifications from the regional epidemiological surveillance system were analyzed, corresponding to 1781 people, along with 217 reports from the Forensic Medical Service of people who died by suicide. Results The overall suicide rate for the region during that period was 9.79 deaths per 100 000 inhabitants. The 2018 rates were standardized according to available information, with direct methods for the regional rate (9.55 per 100 000 inhabitants) and indirect methods for the communes. Rural communes presented higher rates than urban ones. Women showed a higher risk of attempts (OR 1.28; 95% CI 1.23 to 1.33) and a lower risk of suicide compared to men (0.086; 0.06 to 0.13). Young people had a higher risk of suicide attempts and a lower risk of suicide compared to older people. The increased suicide rates in older people (70 to 79 years) during 2020 are noteworthy. Basic education level is a risk variable for suicide (2.21; from 1.15 to 4.23), compared to having higher education. Previous suicide attempts and psychiatric pathology are risk factors. Conclusions Suicide prevalence and related factors are similar to those reported in other studies and national reports, highlighting rurality and higher risk in older male adults. In contrast to suicides, attempts are more frequent in women and young people. A history of mental health problems, previous attempts, and family violence are risk factors for both outcomes. Knowing the patterns of suicidal behavior in the population is fundamental for its prevention.

Epidemiología de la apendicitis aguda en Colombia: Un análisis de las bases de datos administrativas del Ministerio de Salud / Epidemiology of acute appendicitis in Colombia: An Analysis of the Ministry of Health administrative databases

Introducción. La apendicitis aguda es una afección común, con un pico de incidencia entre los 10 y 20 años. La cirugía es el tratamiento preferido y la apendicectomía por laparotomía sigue siendo el estándar, aunque el abordaje laparoscópico ha mostrado menos complicaciones. El objetivo de este artículo fue caracterizar tanto la enfermedad como el tratamiento quirúrgico en Colombia, usando datos de bases oficiales. Métodos. Se accedió a la base de datos del Sistema Integrado de Información para la Protección Social (SISPRO) del Ministerio de Salud de Colombia en febrero de 2023. Se recogieron datos de los pacientes con diagnóstico de apendicitis y con procedimiento de apendicectomía entre 2017 y 2021, y se analizaron por edad, sexo y ubicación geográfica. Resultados. Entre 2017 y 2021 se diagnosticaron 345.618 casos de apendicitis (51,8 % mujeres), con pico de incidencia a los 15-20 años. Se realizaron 248.133 apendicectomías, el 16,7 % por laparoscopia. Los hospitales con más procedimientos reportados estaban en Bogotá, Yopal, Popayán y Florencia. La mortalidad fue de 0,56 % en hombres y 0,51 % en mujeres. Conclusión. La apendicitis es común, con pico a los 10-19 años. Las mujeres tienen mayor probabilidad de apendicectomía, debido a otras afecciones ginecológicas. El acceso a la apendicectomía disminuye la mortalidad; en estos pacientes, el 16 % fue laparoscópica, lo que sugiere que se necesita más entrenamiento y acceso a esta técnica. Este estudio aporta a la comprensión de la epidemiología de la apendicitis y apendicectomías en Colombia.

Introduction. Acute appendicitis is a common condition, with a peak incidence between 10 and 20 years of age. Surgery is the preferred treatment and laparotomy appendectomy remains the standard, although the laparoscopic approach has shown fewer complications. The objective of this article was to characterize both the disease and the surgical treatment in Colombia, using data from official databases. Methods. The Integrated Information System for Social Protection (SISPRO) database of the Ministry of Health was accessed in February 2023. Data with diagnosis of apendicitis and with appendectomy between 2017 and 2021 were collected. Analysis was done by age, gender, and geographic location. Results. Between 2017 and 2021, 345,618 cases of appendicitis were diagnosed (51.8% females), with peak incidence at 15-20 years of age. A total of 248,133 appendectomies were performed, 16.7% by laparoscopy. The hospitals with most reported procedures were located in Bogotá, Yopal, Popayán, and Florencia. Mortality was 0.56% in men and 0.51% in women. Conclusion. Appendicitis is common, peaking at ages 10-19. Women are more likely undergo appendectomy due to other gynecological conditions. Access to appendectomy improves mortality. In these patients, 16% were laparoscopic, suggesting that more training and access to this technique is needed. This study contributes to the understanding of the epidemiology of appendicitis and appendectomies in Colombia.

Cáncer incidental de vesícula: incidencia y factores asociados en pacientes de una institución de la ciudad de Medellín / Incidental gallbladder cancer: Incidence and associated factors in patients from an institution in the city of Medellín

Introducción. El cáncer de vesícula biliar es una de las neoplasias más frecuentes de la vía biliar y la mayoría de los casos se diagnostican de forma incidental o en estadios avanzados. En Colombia existen pocas publicaciones acerca de la prevalencia y características clínicas de pacientes con cáncer insospechado de vesícula biliar. El objetivo de este trabajo fue actualizar la información existente. Métodos. Estudio de tipo transversal basado en registros médicos. Como variable de resultado se definió el hallazgo incidental de patología maligna reportado por un patólogo y el subtipo histológico. Se midieron variables demográficas, clínicas y quirúrgicas. Se calcularon OR con sus respectivos intervalos de confianza (IC95%). Resultados. De los 2630 casos analizados, en cuatro se hizo diagnóstico de cáncer incidental de vesícula, con una prevalencia del 0,15 %. Se encontraron como características asociadas al cáncer incidental de vesícula, la edad, el antecedente de cáncer y la presencia de pólipos. Conclusiones. Esta es una patología poco frecuente en la población evaluada, lo que permite afirmar que no es necesario realizar estudios prequirúrgicos más amplios de forma rutinaria, a menos que el paciente presente alguno de los factores asociados.

Introduction. Gallbladder cancer is one of the most common neoplasms of the bile duct and most cases are diagnosed incidentally or in advanced stages. In Colombia, there are few publications about the prevalence and clinical characteristics of patients with unsuspected gallbladder cancer. The objective of this work was to update the existing information. Methods. Cross-sectional study based on medical records. The incidental finding of malignant pathology reported and the histological subtype were defined as the outcome variable. Demographic, clinical and surgical variables were measured. ORs were calculated with their respective 95% CI. Results. Of the 2630 cases analyzed, four were diagnosed with incidental gallbladder cancer, with a prevalence of 0.15%. Characteristics associated with incidental gallbladder cancer were age, history of cancer and the presence of polyps. Conclusions. This is a rare pathology in the population evaluated, which allows us to recommend that it is not necessary to routinely perform more extensive presurgical studies, unless the patient presents any of the associated factors.

Efecto del confinamiento por COVID-19 en la prevalencia de la enfermedad hepática esteatósica asociada a disfunción metabólica / Effect of COVID-19 lockdown on the prevalence of metabolic dysfunction-associated steatotic liver disease

Introducción. La enfermedad hepática esteatósica asociada a disfunción metabólica (MASLD) es una condición clínica frecuente, relacionada con el sobrepeso, la dislipidemia y la diabetes. Como estos factores de riesgo están a su vez asociados al sedentarismo y la ganancia de peso, se esperaría un impacto como resultado del confinamiento por COVID-19 en la prevalencia de dicha condición. Metodología. Estudio longitudinal retrospectivo en un panel de datos de 132 pacientes de 2017 a 2022, en donde fueron incluidos pacientes con una ecografía hepática y una valoración médica y paraclínica 1,5 años antes y después del periodo de confinamiento (25 de marzo de 2020 a 28 de febrero de 2021). El desenlace primario fue un cambio significativo en la prevalencia de la MASLD, y se utilizó un modelo exploratorio de regresión logística de efectos fijos con panel de datos para hallar los predictores de cambio. Resultados. En un total de 132 pacientes analizados, la prevalencia global de la MASLD antes (31 %; IC95%: 23-39) y después (35,6 %; IC95%: 27,4-43,8) del confinamiento por COVID-19 no cambió significativamente, sin embargo, en las mujeres sí hubo un aumento significativo (RR: 4; IC95%: 1,0004-16). Se encontró una marcada diferencia de prevalencia entre sexos (17 % en mujeres y 46 % en hombres; p=0,001). El confinamiento se asoció a incrementos en la masa corporal (diferencia: +1 kg; IC95%: 0,1-1,9), el colesterol LDL (diferencia: +9,7 mg/dL; IC95%: 4,9-14,4) y al diagnóstico de prediabetes (RR: 2,1; IC95%: 1,4-3,1). La MASLD se asoció positivamente a la preferencia nutricional por la comida rápida (p=0,047). Solo el índice de masa corporal resultó predictor independiente de MASLD (RR: 1,49; IC95%: 1,07-1,93). Conclusión. La prevalencia global de la MASLD no varió después del confinamiento por COVID-19, pero sí se incrementó en mujeres, y algunos de sus factores de riesgo también aumentaron significativamente. Se encontró equivalencia numérica entre la MASLD y la definición previa de la enfermedad. Se requiere un estudio local más grande para desarrollar y validar un mejor modelo predictor del cambio de la MASLD a través del tiempo.

Introduction. Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common clinical condition, related to overweight, dyslipidemia and diabetes. As these risk factors are in turn associated with sedentary lifestyle and weight gain, an impact as a result of the COVID-19 confinement on the prevalence of MASLD would be expected. Methodology. Retrospective longitudinal study in a data panel of 132 patients from 2017 to 2022. Patients with a liver ultrasound and a medical and paraclinical assessment 1.5 years before and after the confinement period (March 25, 2020 to February 28, 2021) were included. The primary outcome was a significant change in the prevalence of MASLD, and an exploratory fixed-effects logistic regression model with panel data was used to find predictors of change. Results. In a total of 132 patients analyzed, the overall prevalence of MASLD before (31%, 95%CI: 23-39) and after (35.6%, 95%CI: 27.4-43.8) confinement by COVID-19 did not change significantly, however, in women there was a significant increase (RR: 4, 95%CI: 1.0004-16). A marked difference in prevalence was found between sexes (17% in women and 46% in men; p=0.001). Confinement was associated with increases in body mass (difference: +1 kg, 95%CI: 0.1-1.9), LDL cholesterol (difference: +9.7 mg/dL, 95%CI: 4.9-14.4) and the diagnosis of prediabetes (RR: 2.1, 95%CI: 1.4-3.1). MASLD was positively associated with nutritional preference for fast food (p=0.047). Only body mass index was an independent predictor of MASLD (RR: 1.49, 95%CI: 1.07-1.93). Conclusion. The overall prevalence of MASLD did not change after the COVID-19 lockdown, but it did increase in women, and some of its risk factors also increased significantly. Numerical equivalence was found between MASLD and the previous definition of the disease. A larger local study is required to develop and validate a better predictor model of MASLD change over time.

Percentage Incidences of Bacteria in Mahseer (Tor putitora), Silver carp (Hypophthalmichthys molitrix) Fish Collected from Hatcheries and Local Markets of District Malakand and Peshawar of Khyber Pakhtunkhwa, Pakistan / Incidências percentuais de bactérias em Mahseer (Tor putitora), carpa-prateada (Hypophthalmichthys molitrix), peixes coletados em incubatórios e mercados locais do distrito de Malakand e Peshawar de Khyber Pakhtunkhwa, Paquistão

Abstract Fish is the main source of animal protein for human diet. The aim of this study was to find out prevalence of pathogenic bacteria of two selected economically important fish of Pakistan namely Mahseer (Tor putitora) and Silver carp (Hypophthalmichthys molitrix). Live fish samples from hatcheries and dead fish samples from different markets of study area were randomly collected. The fish samples were analyzed for isolation, identification and prevalence of bacteria. The isolated bacteria from study fish were identified through biochemical test and about 10 species of pathogenic bacteria were identified including the pathogenic bacteria to human and fish namely, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus iniae, Serratia spp. Citrobacter spp. Stenotrophomonas spp. Bacillus spp. and Salmonella spp. The bacterial percentage frequency of occurrence in Silver carp and Mahseer fish showed Pseudomonas aeruginosa 21.42%, Staphylococcus epidermidis 17.85%, Escherichia coli 11.90%, Staphylococcus aureus 9.52%, Citrobacter spp. 9.52%, Serratia spp. 8.33%, Streptococcus iniae 7.14%, Stenotrophomonas spp. 5.95%, Bacillus spp. 4.76% and Salmonella spp. 3.57%. The study revealed that Fish samples of Mahseer and Silver carp that were collected from markets have found more isolates (10 bacterial species) than did the fresh fish pond samples (03 bacterial species) of hatcheries. The occurrence of pathogenic bacteria in study fish showed risk factor for public health consumers.

Resumo O peixe é a principal fonte de proteína animal para a alimentação humana. O objetivo deste estudo foi descobrir a prevalência de bactérias patogênicas de dois peixes economicamente importantes selecionados do Paquistão, nomeadamente Mahseer (Tor putitora) e carpa prateada (Hypophthalmichthys molitrix). Amostras de peixes vivos de incubatórios e amostras de peixes mortos de diferentes mercados da área de estudo foram coletadas aleatoriamente. As amostras de peixes foram analisadas quanto ao isolamento, identificação e prevalência de bactérias. As bactérias isoladas dos peixes do estudo foram identificadas através de testes bioquímicos e cerca de 10 espécies de bactérias patogênicas foram identificadas incluindo as bactérias patogênicas para humanos e peixes, nomeadamente, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus iniae, Serratia spp. Citrobacter spp. Stenotrophomonas spp. Bacillus spp. e Salmonella spp. A porcentagem de freqüência de ocorrência bacteriana em carpa prateada e peixes Mahseer mostrou Pseudomonas aeruginosa 21,42%, Staphylococcus epidermidis 17,85%, Escherichia coli 11,90%, Staphylococcus aureus 9,52%, Citrobacter spp. 9,52%, Serratia spp. 8,33%, Streptococcus iniae 7,14%, Stenotrophomonas spp. 5,95%, Bacillus spp. 4,76% e Salmonella spp. 3,57%. O estudo revelou que as amostras de peixes de Mahseer e carpa prateada coletadas nos mercados encontraram mais isolados (10 espécies bacterianas) do que as amostras de peixes frescos (03 espécies bacterianas) de incubatórios. A ocorrência de bactérias patogênicas nos peixes do estudo apresentou fator de risco para consumidores de saúde pública.

Prevalence, trends, and factors associated with hypertensive crisis among Peruvian adults / Prevalencia, tendencias y factores asociados a la crisis hipertensiva en adultos peruanos / Prevalência, tendências e fatores associados à crise hipertensiva em adultos peruanos

There are few studies focused on the epidemiology of hypertensive crisis at the population level in resource-constrained settings. This study aimed to determine the prevalence and trends over time of hypertensive crisis, as well as the factors associated with this condition among adults. A secondary data analysis was carried out using the Peruvian Demographic and Family Health Survey (ENDES). Hypertensive crisis was defined based on the presence of systolic (≥ 180mmHg) or diastolic (≥ 110mmHg) blood pressure, regardless of previous diagnosis or medication use. The factors associated with our outcome were evaluated using multinomial logistic regression, and the trend of hypertensive crisis was evaluated using the Cochrane-Armitage test. Data from 260,167 participants were analyzed, with a mean age of 44.2 (SD: 16.9) years and 55.5% were women. Hypertension prevalence was 23% (95%CI: 22.7-23.4) and, among them, 5.7% (95%CI: 5.4-5.9) had hypertensive crisis, with an overall prevalence of 1.5% (95%CI: 1.4-1.6). From 2014 to 2022, a significant decrease in the prevalence of hypertensive crisis was observed, from 1.7% in 2014 to 1.4% in 2022 (p = 0.001). In the multivariable model, males, increasing age, living in urban areas, high body mass index, and self-reported type 2 diabetes were positively associated with hypertensive crisis, whereas higher educational level, socioeconomic status, and high altitude were inversely associated. There is a need to improve strategies for the diagnosis, treatment, and control of hypertension, especially hypertensive crisis.

Pocos estudios se han centrado en la epidemiología de la crisis hipertensiva a nivel poblacional en entornos de recursos limitados. El objetivo de este estudio fue determinar la prevalencia y tendencia, a lo largo del tiempo, de la crisis hipertensiva y los factores asociados a esta condición en adultos. Se realizó un análisis de datos secundarios utilizando la Encuesta Demográfica de Salud Familiar (ENDES) de Perú. La crisis hipertensiva se definió en función de la presencia de presión arterial sistólica (≥ 180mmHg) o diastólica (≥ 110mmHg), independientemente del diagnóstico previo o del uso de medicamentos. Los factores asociados a los resultados se evaluaron mediante regresión logística multinomial, y la tendencia a la crisis hipertensiva se estimó mediante la prueba Cochran-Armitage. Los datos de 260.167 participantes, con una media de 44,2 años (DE: 16,9) y 55,5% mujeres, fueron analizados. La prevalencia de hipertensión fue del 23% (IC95%: 22,7-23,4), de la cual el 5,7% (IC95%: 5,4-5,9) tuvo crisis hipertensiva, con una prevalencia general del 1,5% (IC95%: 1,4-1,6). En el período 2014-2022 se constató una disminución significativa en la prevalencia de crisis hipertensiva, del 1,7% en 2014 al 1,4% en 2022 (p = 0,001). En el modelo multivariable, el sexo masculino, el aumento de la edad, vivir en áreas urbanas, el alto índice de masa corporal y la diabetes autoinformada se asociaron positivamente con la crisis hipertensiva, mientras que mayor nivel educativo, nivel socioeconómico y elevada altitud estuvieron asociadas de manera inversa. Es necesario mejorar las estrategias para el diagnóstico, el tratamiento y el control de la hipertensión, especialmente de la crisis hipertensiva.

Há poucos estudos focados na epidemiologia da crise hipertensiva em nível populacional em ambientes com recursos limitados. O objetivo deste estudo foi determinar a prevalência e a tendência, ao longo do tempo, da crise hipertensiva e fatores associados a essa condição em adultos. Uma análise de dados secundários foi realizada usando a Pesquisa Demográfica de Saúde Familiar (ENDES) do Peru. Crise hipertensiva foi definida com base na presença de pressão arterial sistólica (≥ 180mmHg) ou diastólica (≥ 110mmHg), independentemente de diagnóstico prévio ou uso de medicação. Os fatores associados aos resultados foram avaliados por meio de regressão logística multinomial, e a tendência de crise hipertensiva foi avaliada pelo teste de Cochrane-Armitage. Os dados de 260.167 participantes, com média de 44,2 anos (DP: 16,9) e 55,5% mulheres, foram analisados. A prevalência de hipertensão foi de 23% (IC95%: 22,7-23,4), dentre eles, 5,7% (IC95%: 5,4-5,9) apresentaram crise hipertensiva, com prevalência geral de 1,5% (IC95%: 1,4-1,6). De 2014 a 2022, observou-se queda significativa na prevalência de crise hipertensiva, de 1,7% em 2014 para 1,4% em 2022 (p = 0,001). No modelo multivariável, sexo masculino, idade crescente, residir em área urbana, índice de massa corporal elevado e diabetes autorreferido associaram-se positivamente à crise hipertensiva, enquanto maior escolaridade, nível socioeconômico e altitude elevada associaram-se inversamente. Há necessidade de aprimorar as estratégias de diagnóstico, tratamento e controle da hipertensão arterial, especialmente da crise hipertensiva.

Racial and ethnic disparities in premature births among pregnant women in the NISAMI cohort, Brazil / Disparidades étnicas e raciais nos partos prematuros entre gestantes da coorte NISAMI, Brasil

Abstract The incidence of premature birth has increased worldwide, unequally distributed by race/ethnicity. Racism generates economic inequalities, educational disparities, and differential access to health care, which increases the risk of preterm birth. Thus, this study aimed to evaluate the factors associated with preterm birth and racial and ethnic disparities in premature birth among pregnant women attending prenatal care at the Brazilian Unified Health System health units in the urban area of Santo Antônio de Jesus, Bahia, Brazil. This study used data from 938 pregnant women aged between 18 to 45 years within the NISAMI prospective cohort. Premature birth prevalence was 11.8%, with a higher prevalence among black than non-black women (12.9% versus 6.0%, respectively). Maternal age between 18 and 24 years was the only factor associated with premature birth. A higher risk of premature birth was found among black women than non-black women (RR 3.22; 95%CI 1.42-7.32). These results reveal the existence of racial and social inequalities in the occurrence of premature birth.

Resumo A incidência de parto prematuro tem aumentado em todo o mundo, distribuída de forma desigual por raça/etnia. O racismo gera desigualdades econômicas, disparidades educacionais e acesso diferenciado à saúde, o que aumenta o risco de parto prematuro. Assim, este estudo teve como objetivo avaliar os fatores associados à prematuridade e disparidades raciais e étnicas no parto prematuro entre gestantes atendidas durante o pré-natal em unidades de saúde do Sistema Único de Saúde na zona urbana de Santo Antônio de Jesus, Bahia, Brasil. Este estudo utilizou dados de 938 mulheres grávidas com idade entre 18 e 45 anos dentro da coorte prospectiva do NISAMI. A prevalência de prematuridade foi de 11,8%, sendo maior entre as negras do que entre as não negras (12,9% versus 6,0%, respectivamente). A idade materna entre 18 e 24 anos foi o único fator associado ao parto prematuro. Foi encontrado maior risco de prematuridade entre as mulheres negras do que entre as não negras (RR 3,22; IC95% 1,42-7,32). Esses resultados revelam a existência de desigualdades raciais e sociais na ocorrência do parto prematuro.

Prevalence and clinical consequences of Hepatitis C virus infection in patients undergoing hematopoietic stem cell transplantation

ABSTRACT Hepatitis C virus (HCV) infection is a significant cause of morbidity and mortality among hematopoietic stem cell transplant (HCT) recipients. In Brazil, its occurrence in HCT recipients remains undetermined. We now report on HCV prevalence in HCT recipients and its clinical consequences. The medical records of all HCT recipients seen at Hospital das Clinicas, Sao Paulo University Medical School, from January 2010 to January 2020 were reviewed to determine HCV serostatus. A retrospective analysis of medical charts was undertaken on all seropositive cases to determine HCV genotype, presence of liver fibrosis, co-infections with other viruses, previous treatments, and clinical evolution of liver pathology after HCT. Of the 1,293 HCT recipients included in the study, seven (0.54%) were HCV antibody-positive and five (0.39%) were also viremic for HCV-RNA. Four of these individuals had moderate to severe liver fibrosis (METAVIR F2/F3) and one was cirrhotic. Two of the viremic patients developed acute liver dysfunction following transplantation. All patients had their acute episode of liver dysfunction resolved with no further complications. Four of the viremic patients were treated for HCV infection with direct acting agents (DAA). Information regarding HCV treatment was lacking for one of the viremic HCV patients due to loss of follow up. Sustained anti-virologic responses were observed in three cases after the use of DAA. The detection of HCV in hematological adults undergoing HCT and its successful treatment with DAA highlight the necessity of testing for HCV both prior to and following transplantation.

Frequency of Self-Medication and Knowledge about Out-of-Counter Drugs during the COVID-19 Pandemic in a Group of Iranian Dental Students

Abstract Objective: To study the frequency of self-medication and knowledge about out-of-counter drugs during the COVID-19 pandemic in a group of Iranian dental students. Material and Methods: A descriptive cross-sectional study was conducted among dental undergraduates from September 2021 to November 2021 after receiving ethical clearance from the Kerman Medical University Ethical Committee. A valid and reliable questionnaire, consisting of demographic data and questions about self-medication and knowledge about out-of-counter drugs, was sent to participants via E-mail. Data was analyzed by SPSS 26 software by using a t-test. The P-value was considered at a 0.05% significant level. Results: A total of 88 students participated in the study with a mean age of 21.39±3.71 years. Prevalence of self-medication was found in 53.4%. The most common cause for self-medication was headache. Acetaminophen was the most commonly used medicine for self-medication. Females had more self-medication than males, but there was no significant differences. There was no significant differences between entering year to university and self-medication. Younger students had significantly more self-medication (p=0.007). Knowledge about out-of-counter drugs was moderate. Conclusion: Moderate self-medication as noticed. The out-of-counter drugs were the most used. Although out-of-counter drugs seem relatively safe, their improper use can cause serious side effects. Dental students need to be educated regarding appropriate safe medication and out-of-counter drugs.

Resumo Objetivo Analisar a prevalência e os fatores associados à hospitalização de idosos com COVID-19 no estado do Paraná, PR, Brasil. Métodos Estudo transversal vinculado à coorte "Acompanhamento Longitudinal de adultos e idosos que receberam alta da internação hospitalar por COVID-19", realizado por meio de informações contidas nas fichas de notificação compulsória do Sistema de Informação de Agravos de Notificação. As análises foram realizadas através de frequências relativas e absolutas, com aplicação do teste de qui-quadrado adotado no modelo de regressão logística. A população do estudo englobou pessoas residentes no Estado do Paraná com idade de 60 anos ou mais, hospitalizadas por COVID-19 no período de março de 2020 a setembro de 2021. Resultados Foi identificada maior prevalência de hospitalização entre idosos com escolaridade igual ou maior a oito anos. Indivíduos não vacinados contra COVID-19 apresentaram maior chance de internação. O sexo masculino apresentou mais chance de admissão em Unidade de Terapia Intensiva em comparação com o sexo feminino. Doenças cardiovasculares, pneumopatia e obesidade aumentaram a prevalência da forma grave da doença. Conclusão Fatores tais como escolaridade e não adesão à vacinação contra COVID-19 podem aumentar o risco de hospitalização pela doença. Pessoas idosas do sexo masculino apresentam maior chance de hospitalização na UTI se comparadas às do sexo feminino; além disso, a não utilização de antivirais pode contribuir para o agravamento do estado de saúde.

Resumen Objetivo Analizar la prevalencia y los factores asociados a la hospitalización de personas mayores por COVID-19 en el estado de Paraná.

Individuos no vacunados contra COVID-19 presentaron mayor probabilidad de internación. El sexo masculino presentó más probabilidad de admisión en Unidad de Cuidados Intensivos en comparación con el sexo femenino. Enfermedades cardiovasculares, neumopatía y obesidad aumentaron la prevalencia de la forma grave de la enfermedad. Conclusión Factores tales como escolaridad y no adhesión a la vacunación contra COVID-19 pueden aumentar el riesgo de hospitalización por la enfermedad. Personas mayores de sexo masculino presentaron mayor probabilidad de hospitalización en la UCI al compararlas con las de sexo femenino. Además, la no utilización de antivirales puede contribuir al agravamiento del estado de salud.

Abstract Objective To analyze the prevalence and factors associated with hospitalization of elderly people with COVID-19 in the State of Paraná, PR, Brazil. Methods A cross-sectional study linked to the cohort "Longitudinal Monitoring of adults and elderly people who were discharged from hospital admission due to COVID-19", was carried out using information contained in the compulsory notification forms of the Notifiable Diseases Information System. Analyzes were carried out using relative and absolute frequencies, applying the chi-square test adopted in the logistic regression model. The study population included people aged 60 years or over and residing in the State of Paraná, who were hospitalized for COVID-19 from March 2020 to September 2021. Results A higher hospitalization prevalence was identified among elderly people with eight years of education or more. Individuals not vaccinated against COVID-19 had a greater chance of hospitalization. Males had a greater chance of admission to the Intensive Care Unit compared to females. Cardiovascular diseases, lung disease, and obesity have increased the prevalence of the severe form of the disease. Conclusion Factors such as education and non-adherence to vaccination against COVID-19 can increase the risk of hospitalization due to the disease. Elderly people of the male sex have a greater chance of hospitalization in the ICU compared to the female sex. Furthermore, not using antivirals can contribute to worsening health status.

Trends and age-period-cohort effect on dental caries prevalence from 2008 to 2019 among Brazilian preschoolers

Abstract This study aimed to evaluate trends in the prevalence of dental caries in preschool children and associated factors considering different time variations. This is a time series study performed using data from three cross-sectional studies with pre-school children from southern Brazil in 2008, 2013 and 2019. This children group was born between the years of 2003 to 2018. Dental caries was evaluated by decayed, missing and filled deciduous teeth (dmft index). Demographic, socioeconomic, behavioural and psychosocial variables were also collected. Chi-square test for trends and a hierarchical age-period-cohort (HAPC) analysis using multilevel Poisson regression model for testing the associations between predictor variables and dental caries experience were used. A total of 1,644 pre-school children participated in all surveys. There was a significant difference in caries experience considering all APC effects. The prevalence of dental caries was 25.0% in 2008, 16.3% in 2013, and 19.4% in 2019 (p < 0.01) and no statistical difference was observed. An age effect showed that older children were more likely to experience dental caries. Considering the cohort effect, there is a significant difference between the generations, mainly between 2003 and 2018. Household income, use of dental services, and parent's perception of child oral health were associated with dental caries experience no matter the time variation. Despite recent declines in dental caries prevalence among preschool children, caries levels increased with age and social inequalities persisted through the years, indicating a need of reviewing the policies to reduce the burden of this oral disease.

Is resistance training a protective factor for musculoskeletal injuries in crossfit practitioners? / ¿es el entrenamiento de resistencia un factor protector de las lesiones musculoesqueléticas en crossfit? / Treinamento resistido é um fator de proteção para lesões musculoesqueléticas no crossfit?

ABSTRACT Objective: To evaluate the prevalence and characteristics of musculoskeletal injuries associated with CrossFit® practitioners and the relationship of this prevalence among those who concomitantly perform resistance training (RT). Methods: Cross-sectional study in which adult participants of both sexes were included, who answered a mixed morbidity questionnaire adapted. The participants were allocated into groups according to whether or not they practiced another modality along with CrossFit®, with emphasis on RT. Analytical and descriptive statistics procedures were used, with a statistical significance level of 5% (p<0.05). Results: A total of 179 participants were included in the study. Prevalences of musculoskeletal injuries were observed in the overall study sample of 32.4% and in those who perform CrossFit® with RT of 30.8%. The injury prevalence ratio for this group was 0.95, with lower injury prevalence for the upper limbs (p=0.03) and lower limbs (p=0.02). It is worth noting that 96% of the CrossFit® and RT practitioners did strength training focused only on the upper and/or lower limb musculatures, without specific training for the anatomical segment of the Core (lumbar and pelvis). Conclusion: RT associated with CrossFit® and covering all anatomical segments, can be considered a protective factor for the occurrence of musculoskeletal injuries in CrossFit®. Level of Evidence IV; Case Series.

Nível de Evidência IV; Série de Casos.

Factors Associated with Hyposalivation in Brazilian Adults

ABSTRACT Objective: To determine the occurrence of hyposalivation in Brazilian adults and its association with individual determinants, such as the use of medications, systemic conditions, smoking, and alcohol consumption. Material and Methods: A cross-sectional study with 402 adults was developed. Information was collected on sociodemographic and general health characteristics, and sialometry was performed with stimulated salivary flow. It indicated low salivary flow when ≤ 0.7 mL/min. Bivariate and multivariate analyses were conducted using a decision tree (p<0.05). Results: The sample was comprised predominantly of women (68.2%) aged ≤ 29 years (25.4%). Most participants did not use medication (56.7%). Among systemic diseases, the most cited was hypertension (25.1%). More than a third of the participants presented hyposalivation (40.3%), being associated with the following variables: age between 50 to 59 years (p=0.011), female sex (p<0.001), menopause (p=0.001), use of alcohol (p=0.033), systemic disease (p=0.002) and medication use (p<0.001). In multivariate analysis, in addition to sex (p<0.001) and hypertension (p=0.005), an association was also found between hyposalivation and diabetes (p=0.014). Conclusion: Factors associated with hyposalivation in adults were sex and the presence of hypertension or diabetes.

Dementia prevalence among hospitalized older patients: a multicenter study in Iran / Prevalência de demência entre pacientes idosos hospitalizados: um estudo multicêntrico no Irã

ABSTRACT Dementia poses a significant societal and health challenge in the 21st century, with many hospitalized patients experiencing dementia without a documented diagnosis. Objective: To evaluate the prevalence of dementia and its associated risk factors among older patients admitted to hospitals. Methods: The study included older patients (≥ 60 years) admitted to medical departments of a general hospital in three major Iranian cities. Researchers utilized the Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale, the Geriatric Depression Scale (GDS), the Mini-Cog test, the 4 A's test (4AT), and the Abbreviated Mental Test Score (AMTS). Among the 420 recruited older inpatients, 228 (54.3%) were female. Results: The mean age of participants was 71.39 years (standard deviation ±7.95), with 30.7% diagnosed with major neurocognitive disorder (dementia). The likelihood of dementia exhibited statistically significant correlations with gender, age, number of children, and occupation. Conclusions: Screening older individuals for cognitive impairment upon hospital admission holds the potential to prevent adverse outcomes and enhance the quality of treatment for patients concurrently dealing with dementia.

RESUMO A demência representa um grande desafio social e de saúde no século 21, com muitos pacientes hospitalizados sofrendo de demência sem um diagnóstico documentado. Objetivo: Avaliar a prevalência de demência e seus fatores de risco associados entre pacientes idosos hospitalizados. Métodos: O estudo incluiu pacientes idosos (≥ 60 anos) internados em um hospital geral em três grandes cidades iranianas. Os pesquisadores utilizaram a escala de Atividades da Vida Diária-Atividades Instrumentais da Vida Diária (Activities of Daily Living-Instrumental Activities of Daily Living - ADL-IADL), a Escala de Depressão Geriátrica, o teste Mini-Cog, o teste dos 4 As (4AT) e o Pontuação do Teste Mental Abreviado (Abbreviated Mental Test Score - AMTS). Dos 420 idosos selecionados, 228 (54,3%) eram do sexo feminino. Resultados: A média de idade dos participantes foi de 71,39 anos (desvio padrão ±7,95), sendo 30,7% diagnosticados com transtorno neurocognitivo maior (demência). A probabilidade de demência apresentou correlações estatisticamente significativas com sexo, idade, número de filhos e ocupação. Conclusões: A triagem de idosos para comprometimento cognitivo na admissão hospitalar tem o potencial de prevenir resultados adversos e melhorar a qualidade do tratamento para pacientes que lidam simultaneamente com demência.

Temporal and spatial analysis of over 7,000 measles cases outbreak from 2018 to 2019 in the Brazilian Amazon

ABSTRACT Objective: This study aimed to present a temporal and spatial analysis of the 2018 measles outbreak in Brazil, particularly in the metropolitan city of Manaus in the Amazon region, and further introduce a new tool for spatial analysis. Methods: We analyzed the geographical data of the residences of over 7,000 individuals with measles in Manaus during 2018 and 2019. Spatial and temporal analyses were conducted to characterize various aspects of the outbreak, including the onset and prevalence of symptoms, demographics, and vaccination status. A visualization tool was also constructed to display the geographical and temporal distribution of the reported measles cases. Results: Approximately 95% of the included participants had not received vaccination within the past decade. Heterogeneity was observed across all facets of the outbreak, including variations in the incubation period and symptom presentation. Age distribution exhibited two peaks, occurring at one year and 18 years of age, and the potential implications of this distribution on predictive analysis were discussed. Additionally, spatial analysis revealed that areas with the highest case densities tended to have the lowest standard of living. Conclusion: Understanding the spatial and temporal spread of measles outbreaks provides insights for decision-making regarding measures to mitigate future epidemics.

Determinants of continued breastfeeding in children aged 12-23 months in three regions of Haiti / Determinantes de la continuación de la lactancia materna en la población infantil de entre 12 y 23 meses en tres regiones de Haití / Determinantes do aleitamento materno continuado em crianças de 12 a 23 meses de idade em três regiões do Haiti

ABSTRACT Objectives To identify the prevalence and determinants of continued breastfeeding in Haitian children aged 12-23 months. Methods Three cross-sectional surveys were conducted yearly during the summers of 2017 to 2019 as part of a 4-year (2016-2020) multisectoral maternal and infant health initiative in the regions of Les Cayes, Jérémie, and Anse d'Hainault in Haiti. A total of 455 children 12-23 months of age and their mothers participated in the study. A child was considered to be continuing breastfeeding if the mother reported giving breast milk in the 24-hour dietary recall. Unadjusted and adjusted prevalence ratios were estimated, and associations were assessed between continued breastfeeding and explanatory factors related to sociodemographic characteristics, household food security, maternal nutrition, and breastfeeding knowledge and practices. Results The prevalence of continued breastfeeding was 45.8%. Continued breastfeeding was significantly more prevalent among younger children, children who did not have a younger sibling, children whose mother was not pregnant, those living in the Jérémie region, children who had been exclusively breastfed for less than 1 month, and children whose mother knew the World Health Organization's recommendation for continued breastfeeding up to 2 years or beyond. Conclusions The study results highlight the need for geographically equitable access to tailored and adequate health services and education that support breastfeeding in a way that is compatible with the local context.

RESUMEN Objetivos. Determinar la prevalencia y los determinantes asociados a la continuación de la lactancia materna en la población infantil haitiana de entre 12 y 23 meses. Métodos. Durante los veranos del 2017 al 2019 se llevaron a cabo tres encuestas transversales anuales como parte de una iniciativa multisectorial de salud materna e infantil de 4 años (2016 a 2020) en las regiones de Les Cayes, Jérémie y Anse d'Hainault de Haití. En el estudio participaron 455 menores de edades comprendidas entre 12 y 23 meses y sus madres. Se consideró que un menor continuaba con la lactancia materna si, en la evaluación de la alimentación basada en el recuerdo de 24 horas, la madre declaraba la toma de leche materna. Se calcularon los cocientes de prevalencia ajustados y sin ajustar y se evaluó la asociación entre la continuación de la lactancia materna y posibles factores explicativos relacionados con las características sociodemográficas, la seguridad alimentaria de la familia, la nutrición materna y los conocimientos y prácticas en materia lactancia materna. Resultados. La prevalencia de la continuación de la lactancia materna fue del 45,8%. Esta prevalencia fue significativamente mayor cuando se trataba de lactantes de menor edad, cuando no había hermanos menores, cuando la madre no estaba embarazada, en los residentes en la región de Jérémie, cuando había habido una alimentación exclusiva con leche materna durante menos de un mes y cuando la madre conocía la recomendación de la Organización Mundial de la Salud de continuar con la lactancia materna hasta los dos años o más. Conclusiones. Los resultados del estudio ponen de relieve la necesidad de disponer de un acceso geográfico equitativo a unos servicios de salud y una educación que respalden la lactancia materna de una manera compatible con el contexto local.

RESUMO Objetivos Identificar a prevalência e os determinantes do aleitamento materno continuado em crianças haitianas de 12 a 23 meses de idade. Métodos Três pesquisas transversais foram realizadas anualmente nos verões de 2017 a 2019 como parte de uma iniciativa multissetorial de saúde materno-infantil de quatro anos (2016-2020) nas regiões de Les Cayes, Jérémie e Anse d'Hainault no Haiti. Um total de 455 crianças de 12 a 23 meses de idade e suas mães participaram do estudo. Considerou-se que a criança continuava sendo amamentada se a mãe relatasse ter dado leite materno no recordatório alimentar de 24 horas. Foram estimadas as taxas de prevalência não ajustadas e ajustadas e foram avaliadas as associações entre o aleitamento materno continuado e os fatores explicativos relacionados às características sociodemográficas, à segurança alimentar da família, à nutrição materna e aos conhecimentos e práticas de aleitamento materno. Resultados A prevalência de aleitamento materno continuado foi de 45,8%. O aleitamento materno continuado foi significativamente mais prevalente entre crianças mais novas, crianças que não tinham irmão mais novo, crianças cuja mãe não estava grávida, residentes da região de Jérémie, crianças que haviam sido exclusivamente amamentadas por menos de um mês e crianças cuja mãe conhecia a recomendação da Organização Mundial da Saúde de manter o aleitamento materno por 2 anos ou mais. Conclusões Os resultados do estudo destacam a necessidade de acesso geograficamente equitativo a educação e serviços de saúde adaptados e adequados para apoiar o aleitamento materno de forma compatível com o contexto local.

Prevalence of trachoma in indigenous and non-indigenous areas, Northeastern Brazil, 2019-2021 / Prevalencia del tracoma en zonas de población indígena y no indígena del nordeste de Brasil, 2019-2021 / Prevalência de tracoma em áreas indígenas e não indígenas, Nordeste do Brasil, 2019-2021

ABSTRACT Objective. To estimate the prevalence of trachoma in indigenous and non-indigenous populations in selected areas of the state of Maranhão, in northeastern Brazil. Methods. This was a population-based survey with probabilistic sampling. For the diagnosis of trachoma, external ocular examination was performed using head magnifying loupes, at 2.5X magnification. The prevalence of trachomatous inflammation - follicular (TF) in children aged 1-9 years and the prevalence of trachomatous trichiasis (TT) in the population aged ≥15 years were estimated. Relative frequencies of sociodemographic and environmental characteristics were obtained. Results. The study included 7 971 individuals, 3 429 from non-indigenous populations and 4 542 from indigenous populations. The prevalence of TF in non-indigenous and indigenous populations was 0.1% and 2.9%, respectively, and the prevalence of TT among indigenous populations was 0.1%. Conclusions. The prevalence of TF and TT in the two evaluation units in the state of Maranhão were within the limits recommended for the elimination of trachoma as a public health problem. However, the prevalence of TF was higher in the indigenous evaluation unit, indicating a greater vulnerability of this population to the disease. The prevalence of TF of below 5.0% implies a reduction in transmission, which may have resulted from improved socioeconomic conditions and/or the implementation of the World Health Organization SAFE strategy.

RESUMEN Objetivo. Estimar la prevalencia del tracoma en poblaciones indígenas y no indígenas en determinadas zonas del estado de Maranhão, en el nordeste de Brasil. Métodos. Se trató de una encuesta de ámbito poblacional con muestreo probabilístico. Para el diagnóstico del tracoma, se realizó un examen ocular externo con una lupa frontal de 2,5X aumentos. Se estimó la prevalencia de la inflamación tracomatosa folicular (TF) en la población infantil de 1 a 9 años y la prevalencia de la triquiasis tracomatosa (TT) en la población de 15 años o más. Se obtuvieron las frecuencias relativas de las características sociodemográficas y ambientales. Resultados. En el estudio participaron 7 971 personas, 3 429 de poblaciones no indígenas y 4 542 de poblaciones indígenas. La prevalencia de la TF en las poblaciones no indígenas e indígenas fue de 0,1% y 2,9%, respectivamente, en tanto que la de la TT en las poblaciones indígenas fue de 0,1%. Conclusiones. La prevalencia de la TF y la TT en las dos unidades de evaluación del estado de Maranhão estuvo dentro de los límites recomendados para la eliminación del tracoma como problema de salud pública. Sin embargo, la prevalencia de la TF fue mayor en la unidad de evaluación indígena, lo que indica una mayor vulnerabilidad de esta población a la enfermedad. La prevalencia de la TF inferior al 5,0% implica una reducción de la transmisión, que puede haber sido consecuencia tanto de la mejora de las condiciones socioeconómicas como de la aplicación de la estrategia SAFE de la Organización Mundial de la Salud.

RESUMO Objetivo. Estimar a prevalência do tracoma em populações indígenas e não indígenas em áreas selecionadas do estado do Maranhão, na região Nordeste do Brasil. Métodos. Inquérito de base populacional com amostragem probabilística. Para o diagnóstico de tracoma, foi realizado exame ocular externo com o auxílio de lupas binoculares com ampliação de 2,5×. Foram estimadas a prevalência de inflamação tracomatosa folicular (TF) em crianças de 1 a 9 anos de idade e a prevalência de triquíase tracomatosa (TT) na população com idade ≥15 anos. Foram obtidas as frequências relativas das características sociodemográficas e ambientais. Resultados. O estudo incluiu 7 971 indivíduos (3 429 de populações não indígenas e 4 542 de populações indígenas). A prevalência de TF nas populações não indígenas e indígenas foi de 0,1% e 2,9%, respectivamente, e a prevalência de TT entre as populações indígenas foi de 0,1%. Conclusões. A prevalência de TF e TT nas duas unidades de avaliação no estado do Maranhão ficou dentro dos limites recomendados para a eliminação do tracoma como problema de saúde pública. No entanto, a prevalência de TF foi maior na unidade de avaliação indígena, indicando uma maior vulnerabilidade dessa população à doença. A prevalência de TF abaixo de 5,0% implica uma redução na transmissão, que pode ter sido resultado de melhores condições socioeconômicas e da implementação da estratégia SAFE da Organização Mundial da Saúde.

Drug use among medical students in São Paulo, Brazil: a cross-sectional study during the coronavirus disease 2019 pandemic

ABSTRACT BACKGROUND: Medical students demonstrate higher rates of substance use than other university students and the general population. The challenges imposed by the coronavirus disease 2019 (COVID-19) pandemic raised significant concerns about mental health and substance use. OBJECTIVES: Assess the current prevalence of substance use among medical students at the University of São Paulo and evaluate the impact of the COVID-19 pandemic on drug consumption. DESIGN AND SETTING: A cross-sectional study was conducted on 275 medical students from the University of São Paulo Medical School (São Paulo, Brazil) in August 2020. METHODS: Substance use (lifetime, previous 12 months, and frequency of use before and during the COVID-19 pandemic) and socioeconomic data were assessed using an online self-administered questionnaire. Symptoms of depression were assessed using the Patient Health Questionnaire-9. RESULTS: Alcohol was the most consumed substance in their lifetime (95.6%), followed by illicit drugs (61.1%), marijuana (60%), and tobacco (57.5%). The most commonly consumed substances in the previous year were alcohol (82.9%), illicit drugs (44.7%), marijuana (42.5%), and tobacco (36%). Students in the first two academic years consumed fewer substances than those from higher years. There was a decreasing trend in the prevalence of most substances used after the COVID-19 pandemic among sporadic users. However, frequent users maintained their drug use patterns. CONCLUSION: The prevalence of substance use was high in this population and increased from the basic to the clinical cycle. The COVID-19 pandemic may have affected the frequency of drug use and prevalence estimates.
