Introducción: La calidad de vida relacionada con la salud (CVRS) y los estados de ánimo son indicadores cruciales del bienestar en adolescentes, pero su relación con estudiantes de Antioquia, Colombia, no ha sido ampliamente estudiada. Objetivo: Determinar la CVRS y los estados de ánimo en escolares de Antioquia-Colombia. Materiales y métodos: Estudio transversal con 1957 escolares de 9 a 20 años. Se aplicaron mediciones de CVRS, ansiedad, depresión, hostilidad y alegría, actividad física, comportamiento sedentario, apoyo social de padres y nivel socioeconómico. Resultados: La calidad de vida alta (CVA) es más elevada en hombres, personas con alegría, estudiantes con apoyo de padres, activos físicamente y personas de nivel socioeconómico alto y medio. AL aumentar un año de edad, disminuye en un 15 % la CVA, y al aumentar la depresión, la ansiedad y el comportamiento sedentario disminuye la CVA. Además, los niveles de depresión y ansiedad son mayores en mujeres, estudiantes mayores, sin apoyo de los padres y personas sedentarias. Conclusiones: La CVRS se asocia con estados de ánimo, actividad física, comportamiento sedentario y apoyo de los padres; mientras que los estados de ánimo se asocian con el sexo, el apoyo de los padres, la CVS y el sedentarismo.

Introduction: Even though health-related quality of life (HRQL) and mood states are key indicators of the well-being of adolescents, their relationship has not been analyzed in students from Antioquia, Colombia. Objective: To determine HRQL and mood states in schoolchildren from Antioquia. Materials and methods: A cross-sectional study was conducted on 1,957 schoolchildren and adolescents aged between 9 and 20 years. Measurements of HRQL, anxiety, depression, hostility and happiness, physical activity, sedentary behavior, parental social support, and socioeconomic status were applied. Results: A high quality of life (HQL) was observed more frequently in male participants, students with parental support, physically active, and those belonging to medium and high socioeconomic status. HQL decreased 15% as their age increased by one year. Also, HQL was reduced when depression, anxiety, and sedentary behavior increased. Furthermore, depression and anxiety levels were higher in women, older students, as well as in those without parental control and with sedentary behavior. Conclusions: HRQL is associated with mood states, physical activity, sedentary behavior, and parental support. In contrast, mood states are related to gender, parental support, HQL, and sedentary lifestyle.

Evaluation of the impact of binocular versus monocular cataract surgery using Catquest-9SF: a randomized controlled trial

ABSTRACT Purpose: This prospective, randomized, unmasked, clinical trial aimed to report the visual outcomes of cataract surgery on both eyes versus cataract surgery on one eye in Brazilian patients. Methods: This study included patients with bilateral cataracts and binocular visual acuity worse than or equal to 0.3 logarithm of the minimum angle of resolution. The patients were randomly assigned to undergo surgery on one (Control Group) or both eyes (one eye at a time; Intervention Group). Postoperatively, self-reported visual function using Catquest-9SF (primary outcome measure), binocular visual acuity, stereopsis, and ocular dominance (secondary outcome measures) were compared. Results: A total of 151 patients (77 and 148 eyes in the Control and Intervention Groups, respectively) completed the follow-up. Patients who underwent surgery on both eyes exhibited significantly better self-reported visual function (p=0.036) and stereopsis (p=0.026) than those who underwent surgery on one eye. Binocular visual acuity and ocular dominance did not affect the group comparisons. Conclusions: Surgery on both eyes resulted in significantly better self-reported visual function and stereopsis than surgery on one eye.

ABSTRACT Objective: The aim of this study was to investigate the contextual factors associated with the quality of life (QOL) of Brazilian children aged 0-12 years during the strict period of social isolation. Methods: This observational cross-sectional study was conducted between July and September 2020 using an online questionnaire on QOL-related family factors and the Pediatric Quality of Life Inventory (PedsQL™). Results were analyzed by multinomial logistic regression analysis. Results: The sample had 849 children, mostly from the South Region of Brazil (75%), white (83%), with typical development (79%), sedentary (68%), using screen (85%) for >3 h/day (44%). Their mothers were their main caregivers (90%). The following variables were significantly associated with high scores of QOL: typical health status (OR 2.38; 95%CI 1.60-3.55; screen time ≤2 h/day (OR 1.62; 95%CI 1.17-2.24); social distancing considered as "easy" (OR 1.67; 95%CI 1.20-2.32), and stimulation of the child by the family (OR 1.93; 95%CI 1.08-3.45). Conclusions: This study indicates that the family context can influence children's QOL, especially during the COVID-19 pandemic and home environment reorganization.

XSIM: A structural similarity index measure optimized for MRI QSM.

PURPOSE: The structural similarity index measure (SSIM) has become a popular quality metric to evaluate QSM in a way that is closer to human perception than RMS error (RMSE). However, SSIM may overpenalize errors in diamagnetic tissues and underpenalize them in paramagnetic tissues, resulting in biasing. In addition, extreme artifacts may compress the dynamic range, resulting in unrealistically high SSIM scores (hacking). To overcome biasing and hacking, we propose XSIM: SSIM implemented in the native QSM range, and with internal parameters optimized for QSM. METHODS: We used forward simulations from a COSMOS ground-truth brain susceptibility map included in the 2016 QSM Reconstruction Challenge to investigate the effect of QSM reconstruction errors on the SSIM, XSIM, and RMSE metrics. We also used these metrics to optimize QSM reconstructions of the in vivo challenge data set. We repeated this experiment with the QSM abdominal phantom. To validate the use of XSIM instead of SSIM for QSM quality assessment across a range of different reconstruction techniques/algorithms, we analyzed the reconstructions submitted to the 2019 QSM Reconstruction Challenge 2.0. RESULTS: Our experiments confirmed the biasing and hacking effects on the SSIM metric applied to QSM. The XSIM metric was robust to those effects, penalizing the presence of streaking artifacts and reconstruction errors. Using XSIM to optimize QSM reconstruction regularization weights returned less overregularization than SSIM and RMSE. CONCLUSION: XSIM is recommended over traditional SSIM to evaluate QSM reconstructions against a known ground truth, as it avoids biasing and hacking effects and provides a larger dynamic range of scores.

Development of new PDMS in tube extraction microdevice for enhanced monitoring of polycyclic aromatic hydrocarbons and their derivatives in water.

Contamination by polycyclic aromatic hydrocarbons (PAHs) is an urgent environmental concern, given its atmospheric dispersion and deposition in water bodies and soils. These compounds and their nitrated and oxygenated derivatives, which can exhibit high toxicities, are prioritized in environmental analysis contexts. Amid the demand for precise analytical techniques, comprehensive two-dimensional chromatography coupled with mass spectrometry (GCxGC/Q-TOFMS) has emerged as a promising tool, especially in the face of challenges like co-elution. This study introduces an innovation in the pre-concentration and detection of PAHs using an extraction fiber based on polydimethylsiloxane (PDMS), offering greater robustness and versatility. The proposed technique, termed in-tube extraction, was developed and optimized to effectively retain PAHs and their derivatives in aqueous media, followed by GCxGC/Q-TOFMS determination. Fiber characterization, using techniques such as TG, DTG, FTIR, and SEM, confirmed the hydrophobic compounds retention properties of the PDMS. The determination method was validated, pointing to a significant advancement in the detection and analysis of PAHs in the environment, and proved effective even for traces of these compounds. The results showed that the detection limits (LOD) and quantification limits (LOQ) ranged from 0.07 ng L-1 to 1.50 ng L-1 and 0.33 ng L-1 to 6.65 ng L-1, respectively; recovery ranged between 72 % and 117 %; and the precision intraday and interday ranged from 1 % to 20 %. The fibers were calibrated in the laboratory, with exposure times for analysis in the equilibrium region ranging from 3 to 10 days. The partition coefficients between PDMS and water were also evaluated, showing logarithm values ranging from 2.78 to 5.98. The fibers were applied to the analysis of real water samples, demonstrating high capacity. Additionally, given the growing demand for sustainable methods, the approach presented here incorporates green chemistry principles, providing an efficient and eco-friendly solution to the current chemical analysis scenario.

Introduction: The advancement of the COVID-19 pandemic has resulted in changes in the sleep patterns of the population. Sleep disorders are related to major mental health changes and are also associated with psychosocial factors. Objective: To estimate the prevalence and factors associated with sleep quality changes among users attended in Primary Health Care during the COVID-19 pandemic. Methods: This was a cross-sectional study involving adults (age >18 years) of both genders who were being followed at a healthcare unit. Information was gathered from the unit's electronic medical records, and during home visits (between August and September 2021), socioeconomic data, risk factors, vital signs, anthropometric variables, lifestyle habits, current medications, healthcare service utilization, hospitalization, and consultations in the past year were collected. Quality of life was assessed using the SF-36 questionnaire, and the Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Results: The sample consisted predominantly of women (82.9%) with an average age of 60.5±11.7 years, of white ethnicity (70.7%), with a partner (61%), and belonging to class C (65.8%). 53.7% of the sample had up to two comorbidities, 87.8% were overweight/obese, and 80% were using antihypertensive medication. The prevalence of poor sleep quality was 87.8% (95%CI 73.1­95.0). The findings indicate a relationship between poor sleep quality and alcohol consumption, the presence of ≥3 comorbidities, systolic blood pressure levels, use of anxiolytics, education level, and the use of healthcare services during the pandemic. Conclusions: The high prevalence of poor sleep quality in the study sample suggests that sociodemographic determinants, presence of comorbidities, and lifestyle habits should be considered to minimize the effects of sleep disturbances during the pandemic.

Resumen Objetivo: Ante la escasez de investigaciones que traten de manera conjunta el conocimiento, la calidad y la higiene del sueño en el adolescente, el objetivo del presente estudio es analizar las diferencias y las relaciones que existen entre estas variables en función de características sociodemográficas y personales. Método: A través de los instrumentos Sleep Beliefs Scale (SBS), Spanish Adolescents and Young Adults Pittsburgh Sleep Quality Index (AYA-PSQI-S) y Adolescents Sleep Hygiene Scale Revied (ASHSr), se midieron las características del sueño de 140 estudiantes (M = 16,75; DE = 0,75). Resultados: El 89,3% de los adolescentes presentaban problemas de sueño, subyacentes de la mejorable higiene del sueño por parte del 62,2% y de un escaso conocimiento general del sueño. El sexo femenino y el alumnado en cursos superiores presentaron mayores problemas para conciliar el sueño, somnolencia y una baja gestión cognitiva-emocional (p < 0,05). La higiene del sueño (β = - 0,344), la edad (β = 0,154) y el autoconcepto (β = -0,349) son los factores que predijeron significativamente (p < 0,05) la calidad del sueño del adolescente. Conclusiones: La adquisición de una adecuada higiene del sueño se vuelve fundamental para mejorar la calidad del descanso y la funcionalidad diurna en adolescentes, destacando su importancia, sobre todo, en niveles académicos avanzados y en el caso específico de las mujeres.

Abstract Objective: Given the scarcity of research addressing the intersection of knowledge, sleep quality, and hygiene among adolescents, the primary objective of this study is to analyse the variations and correlations among these variables based on socio-demographic and personal characteristics. Method: The Sleep Beliefs Scale (SBS), the Spanish Adolescents and Young Adults Pittsburgh Sleep Quality Index (AYA-PSQI-S), the Adolescents Sleep Hygiene Scale Revied (ASHSr) were used to measure the sleep characteristics of the 140 Spanish students (M = 16,75; SD = 0,75). Results: Sleep problems were found in 89,3% of the adolescents, underlying poor sleep hygiene in 62,2% and poor general sleep knowledge (SBS = 12,04). Females and students in higher grades presented greater problems in falling asleep, sleepiness, and poor cognitive-emotional management (p < 0,05). Sleep hygiene (β = - 0,344), age (β = 0,154), and self-concept (β = -0,349) were the factors that significantly (p < 0,05) predicted adolescent sleep quality. Conclusions: The acquisition of proper sleep hygiene becomes crucial to enhance the quality of rest and daytime functionality in adolescents, emphasizing its significance, especially in advanced academic levels and specifically in the case of females.

Pilot Study of the Effectiveness of Repetitive Transcranial Magnetic Stimulation on Pain and Quality of Life in Patients with Chemotherapy-Induced Peripheral Neuropathic Pain / Estudio piloto de la eficacia de la estimulación magnética transcraneal repetitiva sobre el dolor y la calidad de vida en pacientes con dolor neuropático periférico inducido por quimioterapia

Abstract Background: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive technique that acts on the activity of the cerebral cortex employing electrical currents. Aim: The objective of this project is to evaluate the effectiveness of rTMS on pain and quality of life in patients with chemotherapy-induced peripheral neuropathic pain. Method: Ten patients with chemotherapy-induced peripheral neuropathic pain received 20 sessions of rTMS, consisting of 15 minutes of treatment repeated 5 times per week for four weeks (10 Hz, 20s, 30 trains with 81% intensity). Patients were evaluated using the Brief pain inventory (BPI) and the Functional Assessment of Cancer Therapy and neurotoxicity (FACT-GOG-NTX 13). Results: There were significant differences in BPI mean severity, interference score and FACT-GOG-NTX 13 (p<0,05). Conclusion: The pilot study results suggest that rTMS is potentially beneficial for the treatment of chemotherapy-induced peripheral neuropathy. rTMS over the M1 had an important reduction in pain severity, interference with daily activities, and quality of life scores. However, results should be taken with caution due to the small sample size, absence of a control group and short period of follow-up.

Objetivo: El objetivo de este proyecto es evaluar la eficacia de la EMTr sobre el dolor y la calidad de vida en pacientes con dolor neuropático periférico inducido por quimioterapia. Métodos: Diez pacientes con dolor neuropático periférico inducido por quimioterapia recibieron 20 sesiones de EMTr que consistieron en un tratamiento de 15 minutos repetido 5 veces por semana durante cuatro semanas (10 Hz, 20 s, 30 trenes con 81 % de intensidad). Los pacientes fueron evaluados mediante el Inventario Breve de Dolor (BPI) y la Evaluación Funcional de la Terapia del Cáncer y la neurotoxicidad (FACT-GOG-NTX 13). Resultados: Hubo diferencias significativas en la severidad media del dolor del BPI, la puntuación de interferencia y el FACT-GOG-NTX 13 (p<0,05). Conclusión: Los resultados del estudio piloto sugieren que la rTMS es potencialmente beneficiosa para el tratamiento de la neuropatía periférica inducida por la quimioterapia. La rTMS sobre M1 tuvo una reducción importante de la severidad del dolor, la interferencia con las actividades diarias y las puntuaciones de calidad de vida. Sin embargo, los resultados deben tomarse con cautela debido al pequeño tamaño de la muestra, la ausencia de un grupo de control y el corto período de seguimiento.

A simple and rapid spectrophotometric method for the determination of trans-chalcone in raw-materialand topical formulation / Método espectrofotométrico simples e rápido paradeterminação de trans-chalcona em matéria-primae em formulação tópica

Trans-chalcone (TC) is a flavonoid precursor characterized by a wide spectrum of action, with anti-inflammatory and antioxidant effects. However, no validated methods are available in official compendia for the analysis of this substance. Thus, the aim of this work was to develop and validate a simple, fast, and reproducible spectrophotometric method for the analysis of TC in raw material, and in topical pharmaceutical formulation containing TC. The established conditions were: methanol as extracting solvent, and detection wavelength of 309 nm by UV spectrophotometer. All tests followed the rules of Resolution RDC 166, 2017. The proposed method was selective. Linearity was demonstrated in the concentration range of 1 to 8 µg/mL (r = 0.999). Repeatability and intermediate precision were confirmed by low relative standard deviation values of 1.53% and 2.70% for TC, and of 1.73% and 2.91% for formulation containing TC. Accuracy, evaluated through recovery test, was adequate, with minimum of 98.24% and maximum of 100.23% of recovery. It was observed that the small deliberate modifications done did not interfere with the results, demonstrating the method is robust. The results showed that the method was considered suitable for the intended purpose, inexpensive, easy to apply, selective, linear, precise, accurate, and robust for the determination TC, and pharmaceutical formulation containing TC. Thus, the method developed satisfies the need for an analytical method for the determination of TC, and topical formulation containing TC, being effective, innovative and able to aid in the development of the pharmaceutical field.

Trans-chalcona (TC) é um precursor de flavonoides caracterizado por um amplo espectro de ação, como efeitos anti-inflamatórios e antioxidantes. No entanto, não há método validado disponível em compêndio oficial para análise deste composto. Então, o objetivo deste trabalho foi desenvolver e validar um método espectrofotométrico, simples, rápido e reprodutível para análise de TC em matéria-prima, e em formulação farmacêutica tópica contendo TC. As condições estabelecidas foram: metanol como o solvente de extração, e detecção no comprimento de onda de 309 nm por espectrofotometria no UV. Todos os testes seguiram as normas da RDC 166, 2017. O método proposto foi seletivo. A linearidade foi demonstrada na faixa de concentração de 1 a 8 µg/mL (r = 0.999). A repetibilidade e a precisão intermediária foram confirmadas pelos valores baixos de desvio padrão relativo de 1,53% e 2,70% para a TC, e de 1,73% e 2,91% para a formulação contendo TC.

Perspectivas dos pais acerca da interação socialde crianças com cicatrizes de queimaduras / Parents' perspectives on the social interactionof children with burn scars

As queimaduras provocam efeitos físicos e psicológicos devastadores nos indivíduos, sobretudo em crianças e adolescentes, e podem modificar a qualidade de vida da pessoa. O objetivo foi analisar o impacto das cicatrizes por queimaduras em crianças menores de oito anos na interação com amigos, família e escola, na perspectiva dos pais. Estudo quantitativo de corte transversal realizado com os pais de crianças <8 anos de idade, vítimas de queimaduras e internadas em um Centro de Tratamento de Queimados no norte do Paraná e acompanhadas ambulatorialmente, de 2017 a 2020. A coleta de dados ocorreu por meio de dois instrumentos: caracterização sociodemográfica e clínica; e Brisbane Burn Scar Impact Profile. Realizou-se análise descritiva e teste Qui-quadrado utilizando-se o SPSS®. Participaram 34 pais cujas crianças sofreram queimaduras, sendo 52,9% de 1 a 3 anos de idade, 58,8% sexo masculino, 82,2% por agente etiológico térmico e a internação foi de 73,5% devido à Superfície Corpórea Queimada ≤20%. Após a alta os pais identificaram que as cicatrizes de queimaduras tinham "um pouco" e "pouco" impacto nas cicatrizes nas relações de amizade e na interação social. Para os pais, prevaleceu a resposta "nada" de impacto, seguido por "um pouco" e "muito" na escola, nas brincadeiras, nos jogos e nas atividades diárias. Quanto às reações emocionais e ao humor, a maior parte dos pais considerou "nada". Nesse sentido, os pais responderam às questões quanto à própria percepção sobre as atividades diárias do seu filho e, em geral, a cicatriz de queimadura não impactou na qualidade de vida da criança.

Burns cause devastating physical and psychological effects on individuals, especially children and adolescents, and can change a person's quality of life. The objective was to analyze the impact of burn scars in children under eight years of age in the interaction with friends, family and school, from the parents' perspective. Quantitative cross-sectional study carried out with the parents of children <8 years old who were victims of burns and admitted to a Burn Treatment Center in northern Paraná and monitored on an outpatient basis, from 2017 to 2020. Data collection occurred using two instruments: sociodemographic and clinical characterization; Brisbane Burn Scar Impact Profile. Descriptive analysis and Chi-square test were performed using SPSS®. 34 parents participated whose children suffered burns, 52.9% aged 1 to 3 years old, 58.8% male, 82.2% due to thermal etiological agent and 73.5% hospitalization was due to Burned Body Surface ≤ 20%. After discharge, the parents identified that the burn scars had "a little" and "little" impact on the scars in friendship relationships and social interaction. For parents, the answer "nothing" of impact prevailed, followed by "a little" and "a lot" in school, play, games and daily activities. As for emotional reactions and mood, most parents considered "nothing" that impacted the child with burn scars. In this sense, parents answered questions regarding their own perception of their child's daily activities and, in general, the burn scar did not impact the child's quality of life.

Diversidad de ninfas de Leptohyphidae (Ephemeroptera) en el río Quenane-Quenanito, piedemonte llanero colombiano / Diversity of Leptohyphidae (Ephemeroptera) nymphs in the Quenane-Quenanito river, Colombian plain foothills

Resumen Introducción: Varias presiones antrópicas sufren los ecosistemas acuáticos del piedemonte llanero en Colombia. La respuesta a estresores ambientales aún se desconoce en organismos bioindicadores como Leptohyphidae. Objetivo: Determinar la diversidad de ninfas de Leptohyphidae del río Quenane-Quenanito, en dos periodos hidrológicos contrastantes y su relación con algunas variables fisicoquímicas. Métodos: En diciembre (2014) y febrero (2015) se recolectaron organismos con red Surber en seis estaciones a lo largo del río. Se analizó la diversidad alfa y beta y se aplicó análisis de redundancia y modelos lineales generalizados con el fin de establecer la relación entre los taxones y las variables ambientales. Resultados: Se identificaron 369 organismos pertenecientes a cuatro géneros (Amanahyphes, Traverhyphes, Tricorythopsis y Tricorythodes), dos especies y ocho morfoespecies. Se reporta por primera vez para el departamento del Meta Amanahyphes saguassu. Se registró la mayor diversidad de ninfas en la transición a la sequía y la mayor abundancia en sequía. La diversidad beta señaló que la configuración del ensamblaje cambia a nivel espacial y temporal. Conclusiones: Los organismos de Leptohyphidae prefieren hábitats de corrientes, particularmente en el periodo de sequía, donde hallan alimento (hojarasca, detritos) y refugio para establecerse exitosamente; actividades antrópicas como la urbanización afectan notablemente la diversidad. La alta diversidad registrada en este pequeño río de piedemonte llanero refleja la necesidad de incrementar este tipo de trabajos y esfuerzos de recolección de material de estudio en la región.

Abstract Introduction: Various anthropic pressures affect the aquatic ecosystems of the foothills of Colombia. The response to environmental stressors is still unknown in bioindicator organisms such as Leptohyphidae. Objective: To determine the diversity of Leptohyphidae nymphs of the Quenane-Quenanito river, in two contrasting hydrological periods and its relationship with some physicochemical variables. Methods: In December (2014) and February (2015), organisms were collected with a Surber net at six stations along the current. Alpha and beta diversity was analyzed and redundancy analysis and generalized linear model were applied to establish the relationship between taxa and environmental variables. Results: Were identified 369 organisms belonging to four genera (Amanahyphes, Traverhyphes, Tricorythopsis, and Tricorythodes), two species, and eight morphospecies. Amanahyphes saguassu is reported for the first time for the Meta department. High diversity of Leptohyphidae nymphs was recorded in the transition to drought season and greater abundance in drought. Beta diversity indicated that the configuration of the assemblage changes spatially and temporally. Conclusions: Leptohyphidae organisms prefer fast habitats, particularly in the dry period where they find food (leaf litter, detritus) and shelter to establish themselves successfully; anthropic activities such as urbanization notably affect diversity. The high diversity recorded in this small river in the foothills of the plains reflects the need to increase this type of works and collection efforts of study material in the region.

Quality of life of families and siblings of children with cerebral palsy treated at a reference neurorehabilitation center in Brazil

Abstract Objectives To investigate the associations between caregivers' burden, family quality of life (QoL), and siblings' QoL in Brazilian families of children with cerebral palsy, and to analyze siblings' QoL using as a parameter the QoL of typically developed Brazilian children. Methods It was a cross-sectional study. The 212 families, 212 caregivers and 131 siblings completed the Family Quality of Life Scale, Burden Interview, and KIDSCREEN-27 Child and Adolescent Version and Parents Version questionnaires at a neurorehabilitation center in southeast Brazil. Univariable and multivariable models were used. Results Family QoL significantly worsened as caregivers' burden increased (95 % CI -0.66 to -0.38). Caregivers' burden was significantly lower with increasing family QoL scores (95 % CI -0.52 to -0.30). Self-reported siblings' QoL was significantly worse than that of their typically developed peers (95 % CI -7.6 to -3.6). Self-reported siblings' QoL was significantly lower as siblings' age (95 % CI -2.52 to -0.59) and caregivers' burden (95 % CI -0.35 to -0.05) increased. Parent-reported siblings' QoL was significantly lower with increasing caregivers' burden (95 % CI -0.45 to -0.16) and higher as family QoL increased (95 % CI 0.09 to 0.37). Conclusions The cross-sectional nature of these data precludes any statement of causality. Family QoL worsened with higher caregivers' burden levels. Lower caregivers' burden scores were associated with a higher family QoL. Siblings' QoL was impaired as compared to typically developed peers, worse among older siblings, and as caregivers' burden increased and better with higher family QoL levels. Future multicenter studies may validate the generalizability of the present findings.

The effect of diets with different inflammatory scores on inflammation and sleep in obese subjects: a randomized controlled trial

SUMMARY OBJECTIVE: The aim of this study was to investigate the effect of different dietary inflammatory index diets on inflammatory markers, anthropometric measurements, and sleep quality in obese subjects. METHODS: This study was conducted in a public hospital in Turkey between November 2021 and May 2022. Participants with pro-inflammatory dietary habits were included in the study. Randomly divided into two groups of 33 participants, they were subjected to an anti-inflammatory diet or a control diet for 8 weeks. The study evaluated the anthropometric parameters, inflammatory biomarkers, and sleep quality indices of the diet groups. RESULTS: Significant reductions in body mass index were observed in both groups, more marked in the anti-inflammatory diet cohort. C-reactive protein levels, indicative of inflammation, also decreased substantially in both groups, with a more marked reduction in the anti-inflammatory diet cohort. Despite the improvement in sleep quality in both groups, the variation was not statistically significant. CONCLUSION: This study demonstrates the importance of anti-inflammatory diets in nutritional strategies for obesity by reducing body mass index and inflammation.

Genetic Variability in the Physicochemical Characteristics of Cultivated Coffea canephora Genotypes.

The objective of this study was to characterize the genetic divergence and selection gains of the physicochemical grains traits of 68 genotypes of C. canephora most cultivated in the Western Amazon. For this purpose, the following characteristics were evaluated over two harvests: aqueous extract, ash, acidity, pH, protein, ether extract, soluble solids, phenolic compounds, soluble sugars, reducing sugars, and non-reducing sugars. The genotype × measurement interaction effect was significant for all characteristics, with a predominant simple interaction, resulting in smaller changes in the ranking of genotypes. Out of a total of 45 genotypic correlation estimates, 8 were significant, of which 5 were related to acidity. The dispersion of the first two components associated with reference points shows that the genotypes BRS3193, AS1, AS2, AS3, N16, CA1, and AS7 were closest to the ideal type of higher performance. Selection for the main characteristic of soluble sugars resulted in estimates of genetic progress lower than those observed using selection indices. The genetic materials present high genetic diversity, allowing the selection of reference plants with high levels of sugars (BRS3193, AS3, GJ25, and LB30), proteins (BRS2357), lipids (GJ30), and phenolic compounds in their green beans (BRS3193) and high water solubility (AS2).

Effect of Gas Exchange Rate, Vessel Type, Planting Density, and Genotype on Growth, Photosynthetic Activity, and Ion Uptake of In Vitro Potato Plants.

The growth of high-quality in vitro potato plants (Solanum stenotomum subsp. stenotomum, Solanum stenotomum subsp. goniocalyx, and Solanum tuberosum subsp. andigena) is affected by multiple biological, operational, and environmental factors. Research on in vitro culture is frequently focused on the species, explant, composition of the culture medium, and incubation conditions, but only limited information is available on the effect of the gas exchange rate and volume of in vitro culture vessels under variable planting densities. In the present study, these factors were evaluated with a set of seven diverse potato landraces. The results were compared to the plants' responses in routinely used in vitro culture vessels, i.e., 13 × 100 mm and 25 × 150 mm test tubes, and GA7® magenta vessels. In vitro potato plants grown in plastic vessels equipped with a HEPA filter delivering a high gas exchange rate developed thicker stems (0.95 mm), a higher total average leaf area (2.51 cm2), increased chlorophyll content in leaves (32.2 ppm), and lower moisture content in their tissues (90.1%) compared to filter systems with lower gas exchange rates. A high planting density of 10 × 10 plants per vessel (360 and 870 mL) negatively affected the average stem width and root length but increased the plant height (3.4 cm). High fluctuations of ion-uptake of NO3-, Ca++, K+, and Na+ were observed between genotypes, with some accessions having a 4.6-times higher Ca++-ion concentration in their tissues (190-234 ppm). The in vitro plants developed more robust stems, longer roots, and larger leaves within in vitro culture vessels equipped with a HEPA filter (high gas exchange rate) compared to the control vessels, in contrast to the chlorophyll content in leaves, which was higher in plants grown in narrow test tubes. Depending on the purpose of the subculture of in vitro plants, their growth and development can be molded using different gas exchange rates, planting densities, and vessel volumes.

Saturated Fatty Acids in Wool as Markers Related to Intramuscular Fat Content in Lambs.

The aim of this study was to identify Longissimus lumborum (LL) muscle from lambs with high IMF content (≥3%) using wool FA. The FA composition was characterized in two sections of wool from Suffolk Down lambs, and its relationship with IMF content assessed. One hundred and forty lambs of similar body weight, body condition score, and age were selected. IMF content from LL muscle, and the wool fat and FA composition of the wool were determined. The proportions of FAs in the wool of lambs with low IMF were 51.96 ± 7.3% of saturated, 31.96 ± 7.7% polyunsaturated, and 16.08 ± 2.3% monounsaturated. Similar proportions of FAs were observed in wool samples of lambs with high IMF. Significant differences were found only in the SFA proportion between groups (p < 0.05). The predominant FAs in the wool samples were C16:0, C17:0, C18:0, C18:1n9c and C18:2n6c, representing over 60% of total FA methyl esters. Correlations were found between the wool FAs C16:1, C17:0, C18:0, C18:1n9c, C24:0, and C22:6n3 in wool samples divided into two sections. Discriminant analysis identified SFAs, particularly FAs C22:0 and C24:0, as potential candidate for predicting lambs with high IMF content with an accuracy of over 92%. These results provide to our knowledge evidence that IMF content could potentially be determined using wool FAs as a non-invasive method.
