ABSTRACT Purpose: To assess the impact of thinness on the outcome of the percutaneous nephrolithotomy (PCNL). Materials and Methods: A matched case–control study was performed using a prospectively collected database of all patients who underwent PCNL between June 2011 and October 2021. The patients were stratified into two groups according to their phenotypic characteristics, arbitrarily defined according to their body mass index (BMI): <20 kg/m2 (Group 1, very thin patients, G<20) and ≥25 kg/m2 (Group 2, non-thin patients, G≥25). Patients were randomly matched based on Guy's Stone Score (GSS) according to case complexity at a ratio of 1:3. Results: A total of 204 patients were enrolled in this study: 51 patients (G<20) and 153 controls (G≥25). Complications occurred in 15.2% of the patients, with 5.4% of these complications classified as major complications (Clavien grade ≥ 3). According to complications there were no significant differences between the groups. The overall complication rates were 17.6% in the G<20 and 14.4% in the G≥25 (p = 0.653). The major complication rates were 3.9% in the G<20 and 5.8% in the G≥25 (p=0.429). No differences in transfusion or urinary fistula rates were found. Conclusions: In this study, very thin patients were not at a higher risk of complications when submitted to PCNL than in those with a BMI of ≥25 kg/m2. Apparently, this technique can be used in these patients, just as it is used in any other type of patient, independently of their BMI. Purpose PCNL. .

SUMMARY: Sarcopenia is a disease characterized by a decline in skeletal muscle mass, strength, and physical performance, leading to a loss of functional capacity. Appendicular skeletal muscle mass (ASMM) is one of the most used measurements to detect skeletal muscle mass loss; nevertheless, its assessment is expensive. Under this context, indirect anthropometric measurements include calf circumference (CC) and appendicular skeletal muscle mass index (SMI). However, these measurements may not be very sensitive in older people with different body mass index (BMI). The aim of this study was to determine the influence of BMI on indirect measurements of ASMM in overweight and obese older people. This study included 57 participants aged 60 years and over from the city of Los Angeles, Chile, divided into two groups according to nutritional status, overweight (OW; n=33; Men=8; Women=25; age, 72 ± 6 years; BMI, 27.54 ± 1.54 kg·m-2) and obesity (OB; n=24; Men=5; Women=19; age, 72. ± 6 years; BMI, 33.70 ± 6.22 kg·m-2). The results showed that 36 % of the variations observed in CC measurements are explained by BMI (p<0.05). Conversely, the variations in SMI are not explained by BMI. In conclusion, BMI in older people can affect CC results, but not SMI. These results contribute to the decision-making process regarding the use of SMI as a better method for the indirect measurement of ASMM in overweight and/or obese older individuals.

RESUMEN: La sarcopenia es una enfermedad caracterizada por una disminución de la masa del músculo esquelético, la fuerza y el rendimiento físico, lo que conduce a una pérdida de la capacidad funcional. La masa de músculo esquelético apendicular (ASMM) es una de las mediciones más utilizadas para detectar la pérdida de masa de músculo esquelético; sin embargo, su evaluación es costosa. En este contexto, las mediciones antropométricas indirectas incluyen la circunferencia de la pantorrilla (CC) y el índice de masa del músculo esquelético apendicular (SMI). Sin embargo, estas mediciones pueden no ser muy sensibles en personas mayores con diferentes índices de masa corporal (IMC). El objetivo de este estudio fue determinar la influencia del IMC en las mediciones indirectas de ASMM en personas mayores con sobrepeso y obesidad. Este estudio incluyó a 57 participantes de 60 años y más de la ciudad de Los Ángeles, Chile, divididos en dos grupos según estado nutricional, sobrepeso (SP; n=33; Hombres=8; Mujeres=25; edad, 72 ± 6 años; IMC, 27,54 ± 1,54 kg·m-2) y obesidad (OB; n=24; Hombres=5; Mujeres=19; edad, 72 ± 6 años; IMC, 33,70 ± 6,22 kg·m-2). Los resultados mostraron que el 36 % de las variaciones observadas en las mediciones de CC son explicadas por el IMC (p<0,05). Por el contrario, las variaciones del SMI no se explican por el IMC. En conclusión, el IMC en personas mayores puede afectar los resultados del CC, pero no el SMI. Estos resultados contribuyen al proceso de toma de decisiones sobre el uso del SMI como un mejor método para la medición indirecta de ASMM en personas mayores con sobrepeso y/u obesidad.

SUMMARY: This study aimed to determine differences in morphological characteristics and body composition between female handball players from the national teams of Montenegro and Kosovo (U16). Thirty-four participants were included in the study, divided into two subgroups. The first subgroup consisted of 18 players from the Montenegro national team, with an average age of 14.68±0.58 years. The second subgroup consisted of 16 players from the Kosovo national team, with an average age of 15.33±0.66 years. Testing was conducted during the qualification rounds for the European Championship took place in Podgorica in 2021. All players were assessed for anthropometric measurements and body composition, with a total of twelve variables: Body height, body weight, hand length, arm span, triceps skinfold, biceps skinfold, subscapular skinfold, abdominal skinfold, calf skinfold, thigh skinfold, body mass index (BMI), and body fat percentage (BF). The Tanita - model BC-418MA was utilized for the assessment of body composition. Differences in morphological characteristics and body composition of the female handball players from the two national teams were determined through discriminant parametric procedures using the T-test for independent samples with statistical significance set at p < .05. The results indicated that the players from the Montenegro team were significantly younger, had significantly greater average body height, body weight, and hand length compared to players from the Kosovo team. Statistical differences between the two treated teams were found in the variable thigh skinfold, while no significant differences were observed in BMI and BF.

RESUMEN: Este estudio tuvo como objetivo determinar las diferencias en las características morfológicas y la composición corporal entre jugadoras de balonmano de los equipos nacionales de Montenegro y Kosovo (U16). Se incluyeron en el estudio 34 participantes, divididas en dos subgrupos. El primer subgrupo consistió en 18 jugadoras del equipo nacional de Montenegro, con una edad media de 14,68 ± 0,58 años. El segundo subgrupo consistió en 16 jugadoras del equipo nacional de Kosovo, con una edad media de 15,33 ± 0,66 años. Las pruebas se llevaron a cabo durante las rondas de clasificación para el Campeonato Europeo que tuvo lugar en Podgorica en 2021. A todas las jugadoras se les evaluaron las medidas antropométricas y la composición corporal, con un total de doce variables: altura corporal, peso corporal, longitud de la mano, envergadura del brazo, pliegue cutáneo del tríceps, pliegue cutáneo del bíceps, pliegue cutáneo subescapular, pliegue cutáneo abdominal, pliegue cutáneo de la pantorrilla, pliegue cutáneo del muslo, índice de masa corporal (IMC) y porcentaje de grasa corporal (GC). Para la evaluación de la composición corporal se utilizó el modelo Tanita BC-418MA. Las diferencias en las características morfológicas y la composición corporal de las jugadoras de balonmano de los dos equipos nacionales se determinaron mediante procedimientos paramétricos discriminantes utilizando la prueba T para muestras independientes con significación estadística establecida en p <0,05. Los resultados indicaron que las jugadoras del equipo de Montenegro eran significativamente más jóvenes, tenían una altura corporal media, un peso corporal y una longitud de la mano significativamente mayores en comparación con las jugadoras del equipo de Kosovo. Se encontraron diferencias estadísticas entre los dos equipos tratados en la variable pliegue cutáneo del muslo, mientras que no se observaron diferencias significativas en el IMC y el GC.

Abstract Introduction Despite the evidence against drain placement after thyroidectomy, there is a lack of consensus on drain use in patients with substernal goiter. Objective To assess the factors that increase the likelihood of drain placement and its impact on postoperative hematoma and other 30-day complications among adult patients undergoing thyroidectomy for substernal goiter. Methods A retrospective cohort study that used data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Adult patients (aged ≥ 18 years) who underwent elective thyroidectomy for substernal goiter from 2016 to 2020 were included. Cases with closed suction neck drains placed upon completion of surgery were included in the drain group, and the remaining cases formed the nondrain group. Results A total of 1,229 patients were included (46.5% with drain placement). The factors that increased the likelihood of drain placement included body mass index (BMI) ≥ 30 kg/m2, score between 3 and 5 on the American Society of Anesthesiologists (ASA) physical status classification, sternal split/transthoracic surgical approach, operative time ≥ 90 minutes, and surgery conducted by otolaryngologists. Patients with clean-contaminated or contaminated wound classifications were less likely to be submitted to drain placement. In addition, drain use had no impact on postoperative hematoma formation but was found to independently increase the risk of prolonged length of hospital stay. Conclusion Thyroidectomy without drain placement might be safe for substernal goiter. However, this decision should be individualized for each patient. Level Of Evidence: 3 30day day ACSNSQIP.

RESUMEN Antecedentes: Las hernias de línea media asociadas a diástasis de los músculos rectos anteriores (DRA) son frecuentes y se ha propuesto el tratamiento de ambas patologías simultáneamente para reducir la recurrencia. Las técnicas mínimamente invasivas permiten el tratamiento adecuado con reducción de complicaciones asociadas a la herida quirúrgica; sin embargo, aún no hay consenso acerca de cuál es la mejor técnica. Objetivo: Evaluar los resultados posoperatorios a corto y mediano plazo de una serie de pacientes con defectos de línea media y DRA tratados con la técnica Trans-umbilical Endoscopic Sublay Repair (TESuR). Material y método: Se realizó un estudio observacional descriptivo retrospectivo de pacientes a quienes se les aplicó técnica TESuR entre diciembre de 2020 y marzo de 2023, con un seguimiento posoperatorio mínimo de 6 meses. Se analizaron variables demográficas y perioperatorias. Resultados: En el período de estudio se realizaron 24 reparaciones. Todos los pacientes fueron varones. La edad promedio fue de 57 años (rango 41-81) y el índice de masa corporal (IMC) de 28,9 (21,7- 36,1) kg/m². El área del defecto fue de 8,8 (4-25) cm2, con una DRA de 5,1 (3-9) cm. La tasa de complicaciones a 30 días posoperatorios alcanzó el 17% (4/24); todas fueron Clavien-Dindo I. Con un promedio de seguimiento de 18,6 meses (rango 6-25) no se detectaron recidivas herniarias, aunque dos pacientes (8%) presentaron recidiva de la DRA. Conclusiones: La técnica TESuR presentó una baja morbilidad sin recidivas, por lo que la consideramos una alternativa segura y eficaz para el tratamiento de la DRA asociada a defectos de la línea media.

ABSTRACT Background: Midline hernias associated with diastasis recti abdominis (DRA) are common. Simultaneous treatment of both conditions has been recommended to reduce recurrence. Minimally invasive techniques allow adequate treatment while reducing surgical site complications. However, there is still no consensus regarding the optimal technique. Objective: The aim of this study was to evaluate the short and mid-term outcomes of Trans-umbilical Endoscopic Sublay Repair (TESuR) in patients with midline defects and DRA. Material and methods: We conducted a retrospective descriptive observational study of patients undergoing TESuR between December 2020 and May 2023, with a minimum postoperative follow-up of 6 months. The demographic and perioperative variables were analyzed. Results: A total of 24 procedures were performed during the study period. All the patients were men. Mean age was 57 years (range 41-81) and body mass index (BMI) was 28.9 (21.7- 36.1) kg/m². Mean size of the defect was 8.8 cm2 (4-25) with a mean diastasis width of 5 cm (3-9). The rate of complications at 30 days was 17% (4/24) and were all are grade 1 of the Clavien-Dindo classification. After a mean follow-up of 18.6 months (range 6-25), there were no hernia recurrences, although 2 patients (8%) had a recurrence of DRA. Conclusions: TESuR showed low morbidity rate and absence of recurrences, constituting a safe and effective option for the management of DRA associated with midline defects.

RESUMEN: El objetivo de este estudio fue establecer un modelo de dinámica de cambio relacionada con la edad para predecir cambios en los indicadores de composición corporal en bomberos profesionales. El estudio incluyó una muestra total de 145 sujetos, incluidos bomberos profesionales de Serbia (Edad: 36,6 ± 7,6 años, mín. - máx.: 21,0 - 52,0 años). Se analizaron cuatro variables básicas: Masa Corporal - MC, Masa Grasa Corporal - MGC, - Masa Muscular Esquelética - MME y Área Grasa Visceral - AGV, así como cinco variables derivadas o indexadas: Índice de Masa Corporal - IMC, Porcentaje de grasa corporal - PGC, porcentaje de masa muscular esquelética - PMME, índice proteína-grasa - IPG e índice de composición corporal - ICC. Los resultados mostraron una dinámica de cambio estadísticamente significativa en función de la edad para ocho de las variables examinadas, mientras que sólo una, MME no fue estadísticamente significativa. La mayor significancia estadística en términos de dinámica de cambio en función de la edad se encontró para la variable AGV (F = 35,241, p = 000) y la variable PMME (F = 31,398, p = 0,000). Los bomberos profesionales de Serbia pertenecen a la categoría de personas con indicadores nutricionales normales. Sin embargo, debido a un aumento dominante de la grasa visceral combinado con una disminución dominante de la PMME, se puede concluir que están expuestos a un riesgo de desarrollar diversas enfermedades crónicas, mientras que las condiciones de trabajo, que promueven ciertos hábitos de vida negativos, también contribuyen al aumento observado de los componentes de la grasa corporal.

SUMMARY: The aim of this study was to establish an age-related dynamic of change model for predicting changes in body composition indicators in professional firefighters. The study included a total sample of 145 subjects, comprising professional firefighters from Serbia (Age: 36.6 ± 7.6 yrs., Min - Max: 21.0 - 52.0 yrs.). Four basic variables were analysed: Body Mass - BM, Body Fat Mass - BFM, Skeletal Muscle Mass - SMM, and Visceral Fat Area - VFA, as well as five derived, or index, variables: Body Mass Index - BMI, Percentage of Body Fat - PBF, Percentage of Skeletal Muscle Mass - PSMM, Protein-Fat Index - PFI, and Index of Body - IBC Composition. The results showed a statistically significant dynamic of change as a function of age for eight of the examined variables, while only one (Skeletal Muscle Mass - SMM) was not statistically significant. The highest statistical significance in terms of dynamics of change as a function of age was found for the variable VFA (F = 35.241, p = 000) and the variable PSMM (F = 31.398, p = 0.000). Professional firefighters in Serbia fall into the category of people with normal nutritional indicators. However, due to a dominant increase in visceral fat (VFA) combined with a dominant decrease in the proportion of skeletal muscles in the body (PSMM), it can be concluded that they are exposed to a risk of developing various chronic diseases, while their working conditions, which promote certain negative lifestyle habits, also contribute to the observed increase in body fat components.

Abstract The scope of this article is to verify if there are differences in factors associated with calcium intake between men and women. It is based on a study conducted with data from a health survey in a sample of 1641 individuals aged 20 years or more living in the urban area of the city of Campinas, in the State of São Paulo. Calcium intake was obtained from a 24-hour recall (24hr recall method) and analyzed according to sociodemographic variables, health behavior, frequency of meals and body mass index (BMI). The existence of associations was verified by multiple linear regression tests, and it was detected that the profile of associated factors differed between genders. Physical exercise in the leisure context was only associated with calcium intake in males, while skin color, smoking, income, overweight/obesity, and frequency of having breakfast only revealed an association in females. Schooling and having snacks were associated with calcium intake in both sexes. The analysis of the associated factors indicates segments of the female and male population in which the importance of calcium intake needs to be more closely examined. Furthermore, it highlights the importance of conducting health analyses stratified by sex due to the different behavioral patterns that prevail between the sexes. women 164 2 Campinas Paulo 24hour hour 24 24hr hr method variables behavior BMI.

Resumo O objetivo do artigo é verificar se existem diferenças entre os sexos quanto aos fatores que se associam à ingestão de cálcio. Estudo realizado com dados de inquérito de saúde, em amostra de 1.640 indivíduos de 20 anos ou mais residentes no município de Campinas-SP. A ingestão de cálcio foi obtida por meio de um recordatório de 24 horas (R24h) e analisada segundo variáveis sociodemográficas, de comportamentos de saúde, frequência de refeições e índice de massa corporal (IMC); a presença de associações foi verificada por meio de testes de regressão linear múltipla. O perfil de fatores associados à ingestão de cálcio diferiu entre os sexos. A prática de atividade física no contexto de lazer só se associou ao consumo de cálcio no sexo masculino, enquanto cor da pele, tabagismo, renda, excesso de peso e frequência do café da manhã mostraram associação apenas no sexo feminino. Escolaridade e realização de lanches intermediários mostraram-se associadas à ingestão de cálcio em ambos os sexos. A análise aponta segmentos da população feminina e masculina em que a importância da ingestão de cálcio precisa ser mais enfatizada; além disso, alerta para a importância do desenvolvimento de análises de saúde estratificadas por sexo em decorrência de diferentes padrões comportamentais que prevalecem entre os sexos. 1640 1 640 1.64 2 CampinasSP.

Abstract Objectives: Age at menarche (MA) is a proxy for biological maturation and a parameter of socioeconomic changes. Worldwide, anticipation of menarche is associated with nutritional transition and excess weight. The objective of this study was to evaluate the MA in Amazonian students and its association with nutritional status, ethnicity, and socioeconomic level. Methods: Cross-sectional study with 1,017 students aged 6 to 17 living in the city of Manaus, Brazil. MA was analyzed by status quo and recall; its association with body mass index (BMI), race, socioeconomic status, and adult height was examined. Results: 559 (51.9%) participants had already experienced menarche. In 91.7%, menarche occurred between 10 and 14 years of age; the mean age at the onset of menarche was 11.9 years. Overweight (11.6 years) and obese (11.4 years) participants reached menarche earlier than those with normal weight (12 years) and lean (12.7 years) participants. The associations between MA and nutritional status showed that overweight and obesity are risk factors for the early occurrence of menarche. MA was not associated with socioeconomic status/parental education or race. However, excess weight was associated with earlier MA in all races and social classes. The adult height was slightly lower in girls with menarche before 12 years old (157.9 vs 159.4 cm). Conclusion: Regardless of socioeconomic level or ethnicity, excess weight was associated with earlier menarche in Amazonian students.

Abstract: Cardiorespiratory fitness can be assessed by direct, indirect, maximal, and moderate effort, running, cycling, or walking methods. Objective: To predict maximum oxygen consumption (V O2max) from the six-minute walk test in schoolchildren. Patients and Method: 459 students were included, 215 were male and 244 were female, aged 11.9 ± 1.3 years. Basic anthropometry and cardiorespiratory fitness were measured using field tests. Multivariate equations were developed to predict the V O2max using the R® Commander v. 4.2.2 software (p < 0.05). Results: The best model predicting V O2max include distance walked in the six-minute walk test, heart rate recovery, age, height, body weight (V O2max [L-min-1] = - 0.0902 + (- 0.0464 x age) + (0.0002 x distance) + (- 0.0019 x HR) + (0.5843 x height) + (0.0353 x weight), R2 = 0.76; error = 0.25 L-min-1)), and also body mass index (V O2max [L-min-1] = - 0.6152 + (0.0399 x age) + (0.0933 x BMI) + (0.0005 x distance) + (- 0.0022 x HR), R2 = 0.57; error = 0.34 L-min-1)), both with p < 0.001. Conclusions: Cardiorespiratory fitness can be estimated based on basic anthropometry and performance on the six-minute walk test.

Abstract This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.

Resumo O objetivo deste artigo é analisar a relação entre ambiente de atividade física (AF) nas escolas, sexo, idade e obesidade em crianças, usando uma abordagem de rede. Trata-se de um estudo transversal com 1.200 crianças (8,1±1,0 anos) de oito escolas públicas do mesmo município. Peso e estatura foram avaliadas para cálculo do Índice de Massa Corporal (IMC) e classificadas como peso saudável ou sobrepeso. Para avaliar o ambiente de AF na escola, foi aplicado um questionário por meio de entrevista com o gestor da escola. A associação entre o ambiente de AF na escola e a obesidade foi testada por meio Análise de Redes realizada no software Jasp.

Resumo O objetivo deste artigo é analisar a relação entre ambiente de atividade física (AF) nas escolas, sexo, idade e obesidade em crianças, usando uma abordagem de rede. Trata-se de um estudo transversal com 1.200 crianças (8,1±1,0 anos) de oito escolas públicas do mesmo município. Peso e estatura foram avaliadas para cálculo do Índice de Massa Corporal (IMC) e classificadas como peso saudável ou sobrepeso. Para avaliar o ambiente de AF na escola, foi aplicado um questionário por meio de entrevista com o gestor da escola. A associação entre o ambiente de AF na escola e a obesidade foi testada por meio Análise de Redes realizada no software Jasp. Foram observadas associações positivas entre o IMC e as aulas de Educação Física (0,847), professor de educação física (0,349), duração do intervalo (0,564) e quadra poliesportiva (0,662). Associações negativas foram observadas com sexo (-0,212), idade (-0,387), AF extracurricular (-0,492) e playground (-0,557). Adicionalmente, os indicadores de centralidade destacaram a AF extracurricular (1,789) como a variável com o maior valor de intermediação, e o IMC com o maior valor de proximidade (2,239) e força (1,230). A AF extracurricular e a presença de playgrounds no ambiente escolar estão associadas a um peso mais saudável em crianças de baixa renda.

Abstract This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.

Abstract In Argentina, obesity has been on the rise since 2005. The factors shown to be associated with obesity are of a socio-environmental and genetic nature. Among the latter, the FTO gene has been the most extensively studied. The aim of the present work was to analyze the relationship between two markers of the FTO gene, namely rs9939609 and rs11075997, and socio-environmental variables with nutritional status in a sample of 155 individuals from Puerto Madryn, Chubut. Body mass index (BMI) and waist-to-height index (WHtR) were calculated, and multiple linear models were tested to determine the influence of genetic and non-genetic variables on these anthropometric indices. Nutritional status was significantly and negatively associated with educational level and physical activity. The allele reported in the literature as risk allele of the marker rs11075997 was significantly associated with an increase in anthropometric indices in an additive model, more so with WHtR than with BMI. It is necessary to carry out work on a larger scale that will allow us to determine the frequency of the genetic markers of predisposition to obesity studied here and their distribution in our country.

Resumen En Argentina, el exceso de peso aumentó continuamente desde el 2005 hasta el presente. Los factores con probada relación con el exceso de peso son socio-ambientales y genéticos. Entre estos últimos, el gen FTO es el más estudiado. El objetivo de este trabajo fue analizar la relación entre dos marcadores del gen FTO (rs9939609 y rs11075997) y variables socio-ambientales con el estado nutricional en una muestra de 155 personas de Puerto Madryn, Chubut. Se calcularon los índices de masa corporal (IMC) y de cintura-talla (ICT), y se probaron modelos lineales múltiples para conocer la influencia de las variables genéticas y no genéticas sobre dichos índices antropométricos. El nivel educativo y la actividad física estuvieron asociados significativamente y de manera negativa con el estado nutricional. El alelo reportado en la literatura como de riesgo del marcador rs11075997 estuvo significativamente asociado con el aumento de los índices antropométricos bajo un modelo aditivo, en mayor medida con el ICT que con el IMC. Es necesario realizar trabajos a mayor escala que permitan identificar la frecuencia de los marcadores genéticos de predisposición a obesidad aquí estudiados y su distribución en nuestro país.

Abstract Objective To analyze the epidemiological data of orthopedic injuries in beach tennis players. Methods We conducted a cross-sectional study, through a questionnaire, with 185 beach tennis players during tournaments and training sessions in two cities. The questionnaire comprised anthropometric data, as well as data on length of time practicing the sport and reported orthopedic injuries. Results We excluded 25 of the 185 interviewees. Of the 160 players studied, 51.9% were male and 48.1%, female. The average age was of 40.4 years, the average height was of 1.73 m, the average weight was of 75.6 kg, and the average body mass index (BMI) was of 25.2 kg/m2. Orthopedic injuries were reported by 48.8% of the participants, 30.0% in the lower limbs, 11.3% in the spine, and 25.0% in the upper limbs, with an incidence of 0.82 per one thousand hours of practice. Correlating the incidence of injuries with age, weight, height, and BMI, we only found relevance between the higher average age in patients with lower- and upper-limb injuries. Players who had no previous experience with other racket sports had fewer injuries. Other parameters, such as gender, use of the two-handed backhand, dominant side, participation in competitions, and practice of other sports did not show statistically significant differences. Conclusion Orthopedic injuries were found in almost half of the beach tennis players, primarily in the lower limbs. Age, experience with other racket sports, category, hours of training per week, and length of time playing the sport influenced the incidence of orthopedic injuries. crosssectional cross sectional study 18 cities 2 interviewees 16 studied 519 51 9 51.9 481 48 1 48.1% female 404 40 4 40. years 173 73 1.7 m 756 75 6 75. kg BMI (BMI 252 25. kgm2 kgm m2 kg/m2 488 8 48.8 participants 300 30 0 30.0 limbs 113 11 3 11.3 spine 250 25.0 082 82 0.8 upperlimb limb parameters gender twohanded handed backhand side competitions differences Age category week 5 51. 48.1 17 7 1. kg/m 48. 30. 11. 08 0.

Resumo Objetivo Analisar os dados epidemiolügicos das lesões ortopédicas nos praticantes de beach tennis. Métodos Foi realizado um estudo transversal, por meio de questionário, em 185 praticantes de beach tennis, durante torneios e treinos, em duas cidades. O questionário consistiu na coleta de dados antropométricos, além de dados relativos ao tempo de prática do esporte e às lesões ortopédicas referidas. Resultados Excluímos 25 dos 185 entrevistados. Dos 160 praticantes estudados, 51,9% eram do sexo masculino, e 48,1%, do feminino. A média de idade foi de 40,4 anos, a média da estatura foi de 1,73 m, a média do peso, de 75,6 kg, e a média do índice de massa corporal (IMC), de 25,2 kg/m2. A presença de lesões ortopédicas foi relatada por 48,8% dos praticantes, sendo 30,0% nos membros inferiores (MMII), 11,3% na coluna, e 25,0% nos membros superiores (MMSS), com incidência de 0,82 a cada mil horas de prática. Correlacionando a incidência de lesões com idade, peso, altura e IMC, encontramos relevância apenas entre a média de idade maior nos pacientes com lesão nos MMII e MMSS. Os jogadores que não tinham experiência prévia com outros esportes com raquete tiveram menos lesões. Demais parâmetros, como sexo, uso do backhand com duas mãos, lado dominante, participação em competições e prática de outros esportes não obtiveram diferenças estatisticamente significantes. Conclusão Lesões ortopédicas foram encontradas em quase a metade dos praticantes de beach tennis, preferencialmente nos MMII. Idade, experiência com outros esportes de raquete, categoria, horas de treino por semana e tempo de prática do esporte influenciaram na incidência de lesões ortopédicas. tennis transversal 18 treinos cidades antropométricos referidas 2 entrevistados 16 estudados 519 51 9 51,9 masculino 481 48 1 48,1% feminino 404 40 4 40, anos 173 73 1,7 m peso 756 75 6 75, kg IMC , (IMC) 252 25, kgm2 kgm m2 kg/m2 488 8 48,8 300 30 0 30,0 MMII, (MMII) 113 11 3 11,3 coluna 250 25,0 MMSS, MMSS (MMSS) 082 82 0,8 parâmetros mãos dominante significantes Idade categoria 5 51, 48,1 17 7 1, (IMC kg/m 48, 30, (MMII 11, (MMSS 08 0,

RESUMEN Los estilos de vida de los estudiantes están influenciados por desafíos académicos, carga horaria y preferencias alimentarias no siempre saludables,situación que puede derivar en agotamiento físico, mental y enfermedades. El presente estudio tuvo como objetivo analizar la relación entre Hábitos Alimenticios (HA), Índice de Masa Corporal (IMC) e Índice de Satisfacción con la Vida y la Comida (ISVC) en 280 estudiantes seleccionados a través de muestreo probabilístico aleatorio. Se aplicó el enfoque hipotético-deductivo. Los resultados han permitido determinar que el Índice de Satisfacción con la Vida (ISV) y el ISVC no están relacionados con el Índice de Alimentación Saludable (IAS). Existe una correlación significativa negativa entre IMC e IAS, indicando que, a mayor índice de alimentación saludable, menor IMC. Sin embargo, el IMC no determina el ISVC, que es subjetivo y personal, relacionándose más con valoraciones personales, familiares, sociales y estilos de vida.

ABSTRACT Students' lifestyles are influenced by academic challenges, workload and not always healthy food preferences, which can result in physical and mental exhaustion and illness. The objective of this study was to analyze the relationship between Eating Habits (HA), Body Mass Index (BMI) and Index of Satisfaction with Life and Food (ISVC) in 280 students selected through random probabilistic sampling. The hypothetico-deductive approach was applied. The results have allowed us to determine that the Life Satisfaction Index (ISV) and the ISVC are not related to the Healthy Eating Index (HEI). There is a significant negative correlation between BMI and HEI, indicating that the higher the Healthy Eating Index, the lower the BMI. However, BMI does not determine ISVC, which is subjective and personal, relating more to personal, family, social and lifestyle assessments.

Abstract Obesity has been associated with poorer reproductive outcomes after ART treatments, affecting the quality of embryos, endometrial receptivity, and the risk of gestational complications. The decision to delay IVF/ICSI treatments to promote weight loss must be carefully considered, especially in older women. Future research should focus on weight loss interventions tailored to patients’ age and BMI, with longitudinal studies to assess the effects of these interventions. Promoting healthy lifestyles and controlled weight loss is essential, but risks and benefits must be carefully weighed to optimize reproductive treatments.

Resumo A obesidade tem sido associada a piores desfechos reprodutivos após tratamentos de PMA, afetando a qualidade embrionária, a recetividade endometrial e o risco de complicações gestacionais. A decisão de adiar tratamentos de FIV/ICSI para promover a perda de peso deve ser considerada nas mulheres mais velhas. A investigação futura deve focar-se em estudos longitudinais para avaliar os efeitos de intervenções de perda de peso adaptadas à idade e ao IMC. A promoção de estilos de vida saudáveis e a perda de peso controlada são essenciais, mas os riscos e benefícios devem ser cuidadosamente ponderados para otimizar os tratamentos reprodutivos.
