Somatotype characteristics of patients with non-dialysis chronic kidney disease and its relationships with physical activity and depression / Características del somatotipo de pacientes con enfermedad renal crónica sin diálisis y su relación con la actividad física y la depresión

SUMMARY: Somatotype characters have been defined for many diseases. However, there is insufficient information on the somatotype characters of chronic kidney patients. The first aim of our study was to define the specific somatotype in patients diagnosed with CKD. The second aim was to investigate the relationship between somatotype characters and physical activity and depression in CKD patients. A total of 88 (52.7 %) patients diagnosed with CKD between January and December 2021 at the Department of Nephrology, Inonu University Hospital (Malatya, Turkey) and 79 (47.3 %) healthy volunteers were included in the study. Somatotype analysis was performed using the Heath-Carter method. Physical activity was assessed with the International Physical Activity Questionnaire (IPAQ) and depressive symptoms with the Beck Depression Inventory (BDI). Analysis revealed that patients had greater medial calf girth (p = 0.036), higher triceps (p = 0.007) and suprailiac (p = 0.042) skinfold thicknesses and higher body mass index (p = 0.007) compared to controls. Patients also had significantly higher endomorphy (patients: 6.57±1.35 vs. controls: 6.04±1.3; effect size (ES): 0.40, p=0.010) and significantly higher mesomorphy (patients: 7.44±2 vs. controls: 6.85±2.3; ES: 0.27, p=0.039) as well as significantly lower ectomorphy (patients: 0.71±0.69 vs. controls: 1.10±0.93; ES: 0.47, p=0.006). Significant positive correlations were also observed between mesomorphy and IPAQ (rho = 0.219, p = 0.04), endomorphy and BDI (rho = 0.423, p 0.001). Significant negative correlations were observed between ectomorph and BDI (rho = -0.325, p = 0.002). We observed that the dominant somatotype was endomorphic mesomorph in patients with CKD. In addition, the fact that CKD patients with ectomorphic body structure have lower depressive symptoms could have an impact on their well-being.

RESUMEN: Se han definido caracteres de somatotipo para muchas enfermedades. Sin embargo, no hay suficiente información sobre los caracteres somatotípicos de los pacientes renales crónicos. El primer objetivo de nuestro estudio fue definir el somatotipo específico en pacientes diagnosticados de ERC. El segundo objetivo fue investigar la relación entre los caracteres del somatotipo y la actividad física y la depresión en pacientes con ERC. Se incluyeron en el estudio un total de 88 (52,7 %) pacientes diagnosticados con ERC entre enero y diciembre de 2021 en el Departamento de Nefrología del Hospital Universitario de Inonu (Malatya, Turquía) y 79 (47,3 %) voluntarios sanos. El análisis del somatotipo se realizó mediante el método de Heath-Carter. La actividad física se evaluó con el Cuestionario Internacional de Actividad Física (IPAQ) y los síntomas depresivos con el Inventario de Depresión de Beck (BDI). El análisis reveló que los pacientes tenían una mayor circunferencia media de la pierna (pantorrilla) (p = 0,036), tríceps (p = 0,007) y pliegues cutáneos suprailíacos (p = 0,042) más altos y un IMC más alto (p = 0,007) en comparación con los controles. Los pacientes también tenían una endomorfia significativamente mayor (pacientes: 6,57±1,35 frente a controles: 6,04±1,3; tamaño del efecto (ES): 0,40, p=0,010) y una mesomorfia significativamente mayor (pacientes: 7,44±2 frente a controles: 6,85±2,3; ES: 0,27, p=0,039) así como una ectomorfia significativamente menor (pacientes: 0,71±0,69 vs. controles: 1,10±0,93; ES: 0,47, p=0,006). También se observaron correlaciones positivas significativas entre mesomorfia e IPAQ (rho = 0,219, p = 0,04), endomorfia y BDI (rho = 0,423, p 0,001). Se observaron correlaciones negativas significativas entre ectomorfo y BDI (rho = -0,325, p = 0,002). Observamos que el somatotipo dominante fue el mesomorfo endomórfico en pacientes con ERC. Además, el hecho de que los pacientes con ERC con estructura corporal ectomórfica tengan menos síntomas depresivos podría tener un impacto en su bienestar.

Body construction and health itineraries: a survey among travestis and trans people in Rio de Janeiro, Brazil / A construção do corpo e itinerários de saúde: um estudo entre travestis e pessoas trans no Rio de Janeiro, Brasil / Construcción corporal e itinerarios de salud: una encuesta entre travestis y personas trans en Río de Janeiro, Brasil

The article examines health itineraries followed by Brazilian travestis, trans men and trans women in the affirmation of their gender, based on the survey Trans Uerj: Health and Citizenship of Trans People in Brazil. The survey's main objectives were to gauge the trans/travesti population's diversity and sociodemographic profile; and to map the various ways they access their rights as citizens, especially to healthcare services and body modification technologies. Interviewers, mainly trans people and travestis, applied 391 questionnaires in the city of Rio de Janeiro and its metropolitan region to interviewees of different social classes, schooling levels and gender identity configurations, contacted through the interviewers' social networks. For defining respondents' gender identities the survey used an original method based on self-definitions, which were then aggregated into 6 categories for data analysis purposes. This article discusses the multiple strategies used by this trans population in gender affirmation processes to gain access to regulated and/or unregulated use of hormones and surgical procedures.

O artigo examina os itinerários de saúde seguidos por travestis e mulheres e homens trans brasileiros na afirmação do seu próprio gênero, com base no inquérito Trans Uerj: Health and Citizenship of Trans People in Brazil. O inquérito teve como objetivos avaliar a diversidade e o perfil sociodemográfico da população trans/travesti e mapear as diversas maneiras pelas quais garantem seus direitos de cidadania, principalmente nos serviços saúde e em tecnologias de modificação do corpo. Os entrevistadores, majoritariamente pessoas trans e travestis, aplicaram 391 questionários na cidade e Região Metropolitana do Rio de Janeiro, com entrevistados/as de diferentes classes sociais, níveis de escolaridade e configurações de identidade de gênero, contatados através das redes sociais dos entrevistadores. A definição da identidade de gênero dos entrevistados usou um método original baseado nas autodefinições; as definições foram agregadas depois em seis categorias para fins de análise dos dados. O artigo discute as múltiplas estratégias utilizadas pela população trans nos processos de afirmação de gênero para obter acesso ao uso regulado e/ou não regulado de hormônios e procedimentos cirúrgicos.

ABSI is a poor predictor of insulin resistance in Chinese adults and elderly without diabetes

ABSTRACT Objective: Recently, a new obesity index (A Body Shape Index, ABSI) based on waist circumference (WC) was developed, and high ABSI corresponds to a more central concentration of body volume. It is well known that central obesity is closely linked with insulin resistance (IR). Therefore, our study aimed to examine the discriminatory power of ABSI for IR in Chinese adults and elderly without diabetes. Subjects and methods: In 2007, a cross-sectional study was made. In this study, 570 individuals without diabetes were available for analysis (male: 56.1%, mean age: 62.3 ± 6.5 years). Insulin resistance was assessed by homeostasis model assessment (HOMA-IR). Areas under the receiver operating characteristic (ROC) curves were determined to identify variables/models that could predict insulin resistance. Results: ABSI was associated with IR, the cut-off points was 0.0785 m11/6kg-2/3 to identifying IR and the area under the ROC (AUC) curve was 0.618 (95%CI: 0.561-0.675), which was not better than body mass index BMI (AUC = 0.753; 95%CI: 0.706-0.801), WC (AUC = 0.749; 95%CI: 0.700-0.797), and fasting plasma glucose (FPG, AUC = 0.752; 95%CI: 0.705-0.799). Furthermore, combination with ABSI could improve the discriminatory power of other variables for IR. The AUC curve increased from 0.753 to 0.771for BMI, 0.749 to 0.754 for WC, 0.752 to 0.769 for FPG, respectively. Conclusions: ABSI is associated with IR in the general Chinese adults and elderly without diabetes, but the discriminatory power for IR is poor. It is recommended that ABSI be used in combination with other variables.

Características clínicas y bioeléctricas determinadas por bioimpedancia en pacientes con enfermedad pulmonar obstructiva crónica / Clinical and bioelectric characteristics determined by bioimpedance in patients with chronic obstructive pulmonary disease

Se realizó un estudio descriptivo y transversal de 99 pacientes con enfermedad pulmonar obstructiva crónica, atendidos en consulta de Neumología del Hospital General Docente Dr Juan Bruno Zayas Alfonso de Santiago de Cuba, del 1 al 15 de febrero de 2015, con vistas a determinar algunos compartimientos de la composición corporal, según el modelo de organización bicompartimental del cuerpo humano y el método de la bioimpedancia eléctrica. En la serie predominaron el sexo masculino y las edades de 50 a 69 años de edad, y los grados III y II, en ese orden de frecuencia, fueron los más representativos de la enfermedad. Por su parte, la desnutrición y la disfunción muscular resultaron 2 factores determinantes de la gravedad clínica y el pronóstico de la afección. De los parámetros bioeléctricos analizados, se ratificó la masa muscular esquelética como el de supervivencia y de morbilidad y mortalidad; asimismo se demostró el ángulo de fase como parámetro de la bioimpedancia, mayormente establecido para el diagnóstico y el pronóstico clínicos

A descriptive and cross-sectional study of 99 patients with chronic obstructive pulmonary disease was carried out. They were assisted in the Pneumology Service Dr Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from February 1st to 15th, 2015 aimed at determining some compartments of body composition, according to the pattern of bicompartment organization of the human body and the method of the electric bioimpedance. In the series there was a prevalence of the male sex aged 50 to 69, and a higher frequency of III and II degrees (in that order) of the disease. On the other hand, malnutrition and muscular dysfunction were the 2 determining factors of clinical severity and prognosis of the disorder. Of the bioelectric parameters analyzed, the skeletal muscular mass was ratified as that of survival, morbidity and mortality; also the phase angle was demonstrated as bioimpedance parameter, mostly established for the clinical diagnosis and prognosis

Somatotype characteristics of normal-weight and obese women among different metabolic subtypes

ABSTRACT Background Obesity is a well known risk factor for the development of metabolic abnormalities. However, some obese people are healthy and on the other hand some people with normal weight have adverse metabolic profile, therefore it can be assumed that there is a difference in physical characteristics amongst these people. The aim of this study was to establish whether there are somatotype differences between metabolically healthy and metabolically obese women who are obese or of normal weight. Subjects and methods Study included 230 women aged 44.76 ± 11.21y. Metabolic status was assessed according to IDF criteria, while somatotype was obtained using Heath & Carter method. Results Significant somatotype differences were observed in the group of women with normal-weight: metabolically healthy women had significantly lower endomorphy, mesomorphy and higher ectomorphy compared to metabolically obese normal-weight women (5.84-3.97-2.21 vs. 8.69-6.47-0.65). Metabolically healthy obese women had lower values of endomorphy and mesomorphy and higher values of ectomorphy compared to ‘at risk’ obese women but the differences were not statistically significant (7.59-5.76-0.63 vs. 8.51-6.58-0.5). Ectomorphy was shown as an important determinant of the favorable metabolic profile (cutoff point was 0.80). Conclusion We concluded that, in addition to fat mass, metabolic profile could be predicted by the structure of lean body mass, and in particular by body linearity.

Lower cardiac vagal tone in non-obese healthy men with unfavorable anthropometric characteristics

Objectives: to determine if there are differences in cardiac vagal tone values in non-obese healthy, adult men with and without unfavorable anthropometric characteristics. Introduction: It is well established that obesity reduces cardiac vagal tone. However, it remains unknown if decreases in cardiac vagal tone can be observed early in non-obese healthy, adult men presenting unfavorable anthropometric characteristics. Methods: Among 1688 individuals assessed between 2004 and 2008, we selected 118 non-obese (BMI <30 kg/m²), healthy men (no known disease conditions or regular use of relevant medications), aged between 20 and 77 years old (42 ± 12-years-old). Their evaluation included clinical examination, anthropometric assessment (body height and weight, sum of six skinfolds, waist circumference and somatotype), a 4-second exercise test to estimate cardiac vagal tone and a maximal cardiopulmonary exercise test to exclude individuals with myocardial ischemia. The same physician performed all procedures. Results: A lower cardiac vagal tone was found for the individuals in the higher quintiles - unfavorable anthropometric characteristics - of BMI (p=0.005), sum of six skinfolds (p=0.037) and waist circumference (p<0.001). In addition, the more endomorphic individuals also presented a lower cardiac vagal tone (p=0.023), while an ectomorphic build was related to higher cardiac vagal tone values as estimated by the 4-second exercise test (r=0.23; p=0.017). Conclusions: Non-obese and healthy adult men with unfavorable anthropometric characteristics tend to present lower cardiac vagal tone levels. Early identification of this trend by simple protocols that are non-invasive and risk-free, using select anthropometric characteristics, may be clinically useful in a global strategy to prevent cardiovascular disease.

Endofenotipos de Distimia: uso racional de psicofármacos / Endophenotypes of Dysthymia: rational use of psychiatric drugs

El trastorno distímico es una patología subdiagnosticada, que genera un malestar clínicamente significativo con deterioro social, laboral o de otras áreas importantes de la actividad de un individuo. La interrelación entre la genética y la influencia ambiental hace que surjan determinadas etiologías de un trastorno psiquiátrico, que se manifiestan con características clínicas diferentes. A éstas las llamamos “características endofenotípicas”. El endofenotipo determinará también una genética psiquiátrica particular, resultante de la relación que haya entre éste y el pool génico del individuo en cuestión, como así también una respuesta a los fármacos utilizados durante el tratamiento. En la Distimia el afrontamiento maladaptativo es un síntoma central; genera sentimientos negativos llevando a la deserción, fracaso o aumento de la respuesta fisiológica al estrés. La diferente modalidad de afrontamiento, predominando o no la ansiedad como síntoma capital, genera dos endofenotipos de esta patología: Distimia Ansiosa (con ansiedad) y Distimia Anérgica (sin ansiedad). Entre los endofenotipos, las diferencias se reflejan en tratamientos específicos: para la Distimia Anérgica se debe modular el sistema noradrenalina/dopamina. Los IRSS no serían la primera elección. Sí, en cambio, fármacos como el bupropion, la venlafaxina, la amisulprida y los antidepresivos tricíclicos; en la Distimia Ansiosa, se deben utilizar antidepresivos que mejoren la neurotransmisión noradrenérgica/serotoninérgica; los Inhibidores de la Recaptación de la Serotonina y la Noradrenalina (SNRI) tienen una mejor respuesta que los Inhibidores Selectivos de la Recaptación de la Serotonina (IRSS), aunque estos también otorgan una buena alternativa.

Dysthymic disorder is an underdiagnosed pathology characterized by clinically significant distress, and impairment in the social, occupational, or other important areas of activity of an individual. The inter relationship between genetics and the environmental influence cause the emergence of certain etiologies from a psychiatric disorder, which manifest with different clinical characteristics. These are called "endophenotypic characteristics". The endophenotype will also determine a particular psychiatric genetics, which results from the relationship between it and the gene pool of the individual in question, as well as a response to the psychiatric drugs used during the treatment. Within dysthymia, maladaptive coping is a central symptom, it generates negative feelings that led to desertion, failure, or to an increase in the physiological response to stress. Each coping modality, whether anxiety prevails as the central symptom or not, generates two endophenotypes of this pathology: anxious dysthymia (dysthymia with anxiety) and Anergic Dysthymia (dysthymia without anxiety). Among the endophenotypes, differences are reflected in specific treatments: in the case of Anergic Dysthymia, the noradrenaline/dopamine system has to be modulated. SSRls would not be the firest choice, but rather, drugs such as bupropion, venlafaxine, amisulpride and tryciclic antidepressants, for the treatment of Anxious Dysthymia, antidepressants have to be used that imporve the noradrenergic/serotoninergic neurotransmission, Serotonin and Noradrenalin Reuptake inhibitors (SNRIs) have a better response than Selective Serotonin Repuptake Inhibitors (SSRIs) have a better response than Selective Serotonin Reuptake Inhibitors (SSRIs), although the latter also provide a good alternative.
