Valores de referencia de espirometría forzada de adultos residentes sobre o bajo 1500 m s. n. m.: revisión sistemática

Introducción: La espirometría es una prueba de función pulmonar usada en la valoración de programas de rehabilitación para evaluar exposiciones a tóxicos y alérgenos, en estudios epidemiológicos y en el desarrollo de ecuaciones de referencia en poblaciones específicas; estos valores pueden variar de acuerdo con la altura. Objetivo: Establecer las diferencias entre los valores de referencia de espirometría forzada en población adulta residentes en alturas mayores y menores a 1500 metros sobre el nivel del mar. Métodos: Revisión sistemática, se encontraron 536 estudios, se evaluaron 66 en texto completo, 33 en calidad metodológica con las listas de chequeo Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies y Quality Assessment of Case-Control Studies; 21 estudios fueron seleccionados para la revisión y 12 surtieron metanálisis. Resultados: Se contó con 48 923 participantes de alturas entre 2,4 y 4440 m s. n. m. Hay diferencias iniciales al relacionar la altura (+/-1500 m s. n. m) con el VEF1 (hombres: DM 0,29; IC: 0,03-0,55; mujeres: DM 0,27; IC: -0,07-0,60) y los valores de referencia con el sexo: CVF (DM 1,31; IC: 1,24-1,37) y VEF1 (DM: 1,03; IC: 0,95-1,11). Se reportó alta heterogeneidad y riesgo de sesgo de publicación. Discusión: Estas diferencias se dan en función de aspectos antropométricos y fisiológicos como la aclimatación y el envejecimiento pulmonar. Los mecanismos que influyen en estos cambios son la adaptación genética, molecular, fisiológica y anatómica, que permiten compensar los efectos de la hipoxia aguda o crónica, lo cual aumenta la ventilación alveolar y los valores espirométricos. Conclusiones: Los valores de referencia de espirometría varían de acuerdo con la altura (mayores en alturas > 1500 m s. n. m) y el sexo (más elevados en hombres). Es necesario contar con evidencias más amplias y contundentes en la temática.

Introduction: Spirometry is a lung function test used in the evaluation of rehabilitation programs to evaluate exposures to toxics and allergens in epidemiological studies and in the development of reference equations in specific populations; these values may vary according to height. Objective: To establish the differences between the reference values of forced spirometry in the adult population living at altitudes greater than and less than 1,500 meters above sea level. Methods: Systematic review a total of 536 studies were found; 66 were assessed in full text and 33 were assessed for methodological quality using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and Quality Assessment of Case-Control Studies checklists; 21 studies were selected for the review and 12 provided meta-analyses. Results: There were 48,923 participants from heights between 2.4 and 4,440 m.a.s.l. There are initial differences when relating height (+/-1,500 m.a.s.l.) with FEV1 (men: MD 0.29; CI: 0.03-0.55; women: MD 0.27; CI: -0.07-0 .60); and the reference values with gender: FVC (MD 1.31, CI: 1.24-1.37) and FEV1 (MD: 1.03, CI: 0.95-1.11). High heterogeneity and risk of publication bias are reported. Discussion: These differences occur based on anthropometric and physiological aspects such as acclimatization and lung aging. The mechanisms that influence these changes are genetic, molecular, physiological and anatomical adaptations that allow compensation for the effects of acute or chronic hypoxia, which increases alveolar ventilation and spirometric values. Conclusions: The spirometry reference values vary according to height (higher at heights >1,500 m.a.s.l.) and sex (higher in men). It is necessary to have broader and more convincing evidence on the subject.

Mortality from Breast Cancer in Women under 50 Years of Age in Colombia / Mortalidade por câncer de mama em mulheres com menos de 50 anos de idade na Colômbia

Abstract Objective To calculate and analyze the mortality rates from breast cancer in women under 50 years of age in Colombia and to compare them with those of other countries in the region. Methods Based on data from the registry of deaths in 2018 and the results of the National Population and Housing Census of Colombia for the same year, specific mortality rates in women with breast cancer, specific mortality according to age group, standardized by age, proportional mortality, potential years of life lost, and years of life expectancy lost in women under 50 years of age who died from breast cancer were calculated. The mortality rate of regional countries was consulted on the Global Cancer Observatory webpage. Results In the group from 20 to 49 years, the specific mortality rate was higher in the age range from 45 to 49 years, with a rate of 23.42 × 100,000, a value that was above the specific mortality rate due to breast cancer in women in Colombia, 15.17 × 100.000. In the age range of 45 to 49 years, the potential years of life lost were 42.16. Of the 0.275 years of life expectancy lost by the population due to this neoplasia, women under 50 years of age represented 0.091 (33%). Colombia is the fifth in the rank of mortality in Latin American countries in this age group. Conclusion Breast cancer in patients from 30 to 59 years is the number one cause for the decrease in life expectancy of women in Colombia. Women under 50 years of age represent one third of this decrease. This neoplasm is also the leading cause of mortality in women younger than 50 years in South America.

Bullous pemphigoid in India: Review of cases registered in an autoimmune bullous disease clinic

Background: Information on bullous pemphigoid in an Indian context is scarce. Aim: To report clinico-demographic profile, associated comorbidities and prescription pattern of bullous pemphigoid patients in India. Methods: This was a retrospective study, where past records of all bullous pemphigoid patients diagnosed and treated between November 2013 and October 2019 were accessed and analysed. Patients having a compatible clinical presentation with either histopathological and/or direct immunofluorescence evidence of bullous pemphigoid were included. Results: There were 96 bullous pemphigoid patients, with a male: female ratio of 1.6:1. The mean age at diagnosis was 62.5 ± 2.2 years, with mean duration of illness 27.5 ± 4.5 months before presentation. Comorbidities were present in 80 (83%) patients, with type 2 diabetes mellitus (38.5%), hypertension (36.4%) and neurological illness (16.7%) being the commonest ones. Clinically, blisters were the predominant presentation in 81 (84.4%) patients. The majority (87.5%) of patients showed a predominant eosinophilic infiltrate on histopathology. Direct immunofluorescence revealed immunoglobulin G deposits with complement C3 in 77 (80.2%) cases. The majority of patients (77.1%) were treated with oral prednisolone, either alone (11.5%) or in combination (65.6%) with other topical and systemic agents. Topical steroids were used in 29.1%, azathioprine in 28%, dapsone in 16.7% and omalizumab in 6.2% of patients. Limitations: The study is retrospective. Immunofluorescence on salt split skin, direct immunofluorescence serration pattern analysis, and immunoblotting were not performed. Hence, there is a possibility that a few included cases were suffering from other subepidermal autoimmune bullous diseases like epidermolysis bullosa acquisita or anti-p200 pemphigoid. Conclusion: Bullous pemphigoid patients in this study had a younger age of onset and showed male preponderance. Comorbidities like type 2 diabetes, hypertension and neurological disorders were freq

Clinical characteristics of early-onset gastric cancer. A study in a Colombian population

Gastric cancer is a multifactorial disease with important genetic and environmental factors. It is the fifth most common cancer in incidence, and the fourth cause of death secondary to cancer. The incidence of early-onset gastric cancer is increasing worldwide, but clinical information on these patients has not been well established. We analyzed the association between age and clinical, endoscopic, and histopathological characteristics of gastric cancer at the time of diagnosis in a Latin American population. A retrospective and descriptive cross-sectional study was carried out using the database of the Gastroenterology Service of the Clínica Foscal and Clínica Foscal Internacional in Bucaramanga, Colombia. Between January 2016 and December 2019, 259 de novo gastric cancer cases were diagnosed, of which 36 patients (13.9%) were 40 years old or younger. In patients with early-onset gastric, the prevalence of gastric cancer diagnosis was lower in men. A family history of gastric cancer or any other neoplasm was not associated with a higher prevalence of gastric neoplasms. In young patients, vomiting and ascites were more common, the preferred anatomical location was the body of the stomach, and the Borrmann IV classification and the diffuse-type histology were more likely. Our study showed an approximation of the characteristics of early-onset gastric cancer in a Latin American population, where we observed that early-onset gastric cancer has different demographic, anatomical, and histological features than late-onset gastric cancer.

El cáncer gástrico es una enfermedad multifactorial con importantes factores genéticos y ambientales. Es el quinto cáncer más común en incidencia y la cuarta causa de muerte secundaria al cáncer. La incidencia del cáncer gástrico de inicio temprano está aumentando en todo el mundo, pero la información clínica sobre estos pacientes no está bien establecida. Analizamos la asociación entre la edad y las características clínicas, endoscópicas e histopatológicas del cáncer gástrico al momento del diagnóstico en una población latinoamericana. Se realizó un estudio retrospectivo y descriptivo de corte transversal utilizando la base de datos del Servicio de Gastroenterología de la Clínica Foscal y Clínica Foscal Internacional en Bucaramanga, Colombia. Entre enero de 2016 y diciembre de 2019 se diagnosticaron 259 casos de cáncer gástrico de novo, de los cuales 36 pacientes (13,9%) tenían 40 años o menos. En pacientes con enfermedad gástrica de inicio temprano, la prevalencia del diagnóstico de cáncer gástrico fue menor en los hombres. El antecedente familiar de cáncer gástrico o cualquier otra neoplasia no se asoció con una mayor prevalencia de neoplasias gástricas. En pacientes jóvenes fueron más frecuentes los vómitos y la ascitis, la localización anatómica preferida fue el cuerpo del estómago, siendo más probable la clasificación de Borrmann IV y la histología de tipo difuso. Nuestro estudio mostró una aproximación a las características del cáncer gástrico de inicio temprano en una población latinoamericana, donde observamos que el cáncer gástrico de inicio temprano tiene diferentes características demográficas, anatómicas e histológicas que el cáncer gástrico de inicio tardío.

Role of Dietary Management and Physical Activity in Control of Hypertension in Rural Areas of Punjab-A Cross-sectional Study

Introduction: As reported by WHO, hypertension is the third ‘killer’ disease, accounting for one in every eight deaths worldwide. Many modifiable and non-modifiable risk factors are found to be associated with the disease. The present study aims to determine the role of dietary management and physical activity in the control of hypertension in a given population. Material and Methods: A cross-sectional study was conducted that. Study included all hypertensive patients (290) from the field practice area of a tertiary care institute. A self-constructed, pretested questionnaire was used to enquire about the socio- demographic factors and other risk factors associated with hypertension. The data was analyzed using SPSS 23 and valid conclusions were drawn by using the chi-square test. Results: Out of 290 patients, 204 (70.3%) were females and 86 (29.7%) were males. Univariate analysis identified decreased salt intake, decreased fatty food consumption, physical activity, stress management, and spiritual help as highly significant factors affecting hypertension. On multivariate analysis, physical activity, stress management and spiritual help were found to be significant. Conclusion: The study showed that physical activity, stress management and spiritual help were significantly associated with hypertension control among the elderly. Measures should be taken to create awareness about lifestyle modifications in the control of hypertension.

A Study of Clinico-social Profile of Animal Bite Patients Attending the Antirabies Clinic of BRD Medical College, Gorakhpur

Background: Rabies is one of zoonotic viral disease, estimated to cause 59000 human deaths annually in over 150 countries, of which 20,000 are from India alone; about 40% of which are in children under the age of 15. Rabies though 100% fatal is preventable with post-exposure prophylaxis which includes wound washing, anti-rabies vaccination and rabies immunoglobulin. Objective: To describe the clinico-social profile of animal bite patients attending the anti-rabies clinic of BRD Medical College, Gorakhpur. Methodology: A cross-sectional study was conducted in the anti-rabies clinic of Nehru hospital, BRD Medical College, Gorakhpur from January 2022 to May 2022. Study participants were interviewed by using a pre-phrased, pre-designed and pre-tested questionnaire. Data regarding socio-demographic and clinical profile of the study participants following animal bite exposure was collected. Results: The total number of animal bite victims were 250, in which majority of them were males (76.77%) and highest percentage was of adult population (20-59 years). Maximum number of victims were from rural area (78.70%). 19.35% were working and 39.35% were students. 77.43% were category III bites and in 50.96% cases lower limb was the site of bite and dogs were responsible for 89.67% of the bites. 60.64% victims did not wash the wound properly before reaching the anti-rabies clinic. Conclusion: This study concludes that as majority of the animal bite victims were students and majority of victims were unaware about the importance of wound care, therefore a step can be taken to create awareness in various schools.

Comparison of Demography, Resource Utilization and Outcomes of COVID 19 patients admitted during First and Second waves at a tertiary care institute in Kanyakumari, South India

Introduction: The novel Coronavirus disease 19 (COVID-19) affected India, predominantly in two time periods – the first wave from March to December 2020, and the second wave that raged from April to July 2021. Although the time duration of second wave was shorter than the first, the onslaught of the disease was much more severe during the second wave. Objective: To compare the demographic characteristics and clinical outcomes of COVID-19 patients admitted during the first and second pandemic waves. Method: Demographic characteristics, duration of hospitalization, critical unit admission, and mortality data of 137 and 345 COVID-19 positive individuals, from first and second waves respectively, were retrospectively analyzed in a teaching hospital in South India. Descriptive statistics, Independent t test, chi square tests and regression analysis were used for statistical analysis, with significance level prefixed at 5%. Results: Median age of hospitalisation was 46.2 years and 48.39 years during first and second waves respectively, with male preponderance in second wave. There was a statistically significant difference in mean duration of stay (9.04 days v/s 7.53 days), mean Spo2 at admission (98.4% v/s 96.6%), ventilation requirement (1.5% v/s 8.7%), oxygen requirement and ICU care between the two waves.Conclusion: During the second COVID wave, significantly higher hospitalisation rates, intensive care requirements and inpatient mortality was observed. Elevated C Reactive Protein levels, lymphocytopenia, history of diabetes and other co-morbidities were associated with poor outcomes in both waves.

Genomic constellations of RVA detected in Brazil from 1986 to 2016: a temporal and geographical distribution and occurrence of reassortments / Constelações genômicas de RVA detectadas no Brasil de 1986 a 2016: uma distribuição temporal e geográfica e ocorrência de rearranjos

INTRODUCTION: Species A rotavirus (RVA) infections are a major cause of severe gastroenteritis in children of <5 years worldwide. In Brazil, before vaccination, RVA was associated with 3.5 million episodes of acute diarrheal disease per year. Due to the segmented nature of their genomes, rotaviruses can exchange genes during co-infections, and generate new virus strains and new reinfections. OBJECTIVE: To evaluate the genomic diversity of RVA isolated in Brazil in 30 years, between 1986 to 2016, to investigate possible changes in the frequency of genotype constellations before and after the implementation of the vaccine. METHODS: In total, 4,474 nucleotide sequences were obtained from the Virus Variation Database. Genomic constellation was compared, and the proportion of rotavirus genotypes was analyzed by time and geographic region. RESULTS: Our results showed that major known genotypes were circulating in the country during the period under analysis, with a prevalence of the G1P[8] Wa-like genotype, decreasing only in the period immediately after the introduction of the vaccine. Regarding the geographical distribution, most of our constellations, 62 (39.2%), and 50 (31.6%) were concentrated in the North and Northeast regions. Our analysis also showed the circulation of multiple strains during the periods when the DS-1-like and AU-1-like genotypes were co-circulating with the Wa-like genotype. CONCLUSION: Therefore, it is likely that inter-genogroup reassortments are still occurring in Brazil and so it is important to establish an efficient surveillance system to follow the emergence of novel reassorted strains that might not be targeted by the vaccine.

INTRODUÇÃO: As infecções por rotavírus A (RVA) são uma das principais causas de gastroenterite grave em crianças <5 anos em todo o mundo. No Brasil, antes da vacinação, o RVA estava associado a 3,5 milhões de episódios de diarreia aguda por ano. Devido à natureza segmentada de seus genomas, os rotavírus podem trocar genes durante as coinfecções, gerar novas cepas de vírus e novas reinfecções. OBJETIVO: Avaliar a diversidade genômica de RVA isolados no Brasil entre 1986 a 2016 para investigar possíveis alterações na frequência das constelações de genótipos antes e após a implantação da vacina. MÉTODOS: No total, 4.474 sequências de nucleotídeos foram obtidas do Banco de Dados de Variação de Vírus. A constelação genômica foi comparada e a proporção dos genótipos de rotavírus foi analisada por tempo e região geográfica. RESULTADOS: Nossos resultados mostraram que os principais genótipos conhecidos circulavam no país no período em análise, com prevalência do genótipo G1P[8] Wa-like, diminuindo apenas no período imediatamente após a introdução da vacina. Em relação à distribuição geográfica, a maioria das nossas constelações, 62 (39,2%) e 50 (31,6%), concentrava-se nas regiões Norte e Nordeste. Nossa análise também mostrou a circulação de cepas múltiplas durante os períodos em que os genótipos DS-1-like e AU-1-like estavam co-circulando com o genótipo Wa-like. CONCLUSÃO: Portanto, é provável que rearranjos inter-genogrupos ainda estejam ocorrendo no Brasil e por isso é importante estabelecer um sistema de vigilância eficiente para acompanhar o surgimento de novas cepas rearranjadas que podem não ser protegidas pela vacina.

Current management of upper lid ptosis: a web-based international survey of oculoplastic surgeons / Tratamento atual da ptose da pálpebra superior: estudo internacional baseado em questionário eletrônico envolvendo cirurgiões oculoplásticos

ABSTRACT Purpose: This study aimed to evaluate the current practice patterns for assessing and managing upper lid ptosis among members of the Latin American and Spanish societies of Ophthalmic Plastic and Reconstructive Surgery. Methods: An e-mail was sent to invite members of both societies to participate in this anonymous web-based survey. The survey collected data on surgeons' demographics and four other sections: upper lid ptosis preoperative evaluation, surgical preferences, postoperative management, and complications. The frequency and proportions of the responses were then statistically analyzed. Results: The survey was responded by 354 experienced oculoplastic surgeons, 47.7% of whom generally performed more than 20 upper lid ptosis surgeries annually. Of those respondents, 244 (68.9%) routinely check for dry eye preoperatively. Less than half of the respondents (47.4%) perform the phenylephrine test for congenital or acquired ptosis. Mild upper lid ptosis was reported to be usually corrected with conjunctival mullerectomy (43.6%). Severe upper lid ptosis was reported to be usually corrected with frontalis surgery (57%), followed by anterior levator resection, mainly supramaximal resection (17.5%). In cases of severe congenital ptosis, the main reason for surgery was to alleviate the risk of amblyopia (37.3%). An anterior approach was reported to be usually (63.3%) used to manage involutional ptosis associated with dermatochalasis. Common complications comprised undercorrection after levator resection (40%) or frontalis suspension (27.5%). Conclusions: This study reports the current practice patterns among Spanish and Latin American oculoplastic surgeons in upper lid ptosis diagnosis and treatment. Surgeons can use this study data to compare disease management with their colleagues.

RESUMO Objetivo: Avaliar a prática e tratamento da ptose da pálpebra superior por membros das sociedades latino-ame­ricanas e espanhola de Cirurgia Plástica Ocular. Métodos: Os membros das referidas sociedades foram convidados por e-mail para responder a um questionário eletrônico garantindo o anonimato. O questionário constou de dados demográficos do cirurgião e outras quatro seções: avaliação pré-operatória da ptose da pálpebra superior, preferências cirúrgicas, conduta pós-operatória e complicações. Estatística descritiva foi utilizada para análise da frequência e proporções percentuais. Resultados: Trezentos e cinquenta e quatro experientes cirurgiões oculoplásticos dos quais 47,7% realizam mais de 20 cirurgias de ptose da pálpebra superior por ano responderam ao questionário. Na avaliação pré-operatória, 68,9% realizam testes para olho seco, mas o teste da fenilefrina é feito por menos da metade dos entrevistados (47,4%). A ptose da pálpebra superior leve geralmente é corrigida por conjuntivo-mullerectomia (43,6%), a ptose da pálpebra superior grave por cirurgia do músculo frontal (57%) ou ressecção da aponeurose do levantador via anterior, principalmente usando a supramáxima (17,5%). O principal motivo para operar a ptose congênita grave é o risco de ambliopia (37,3%). A ptose involucional associada à dermatocálase costuma ser corrigida pela via anterior (63,3%). Hipocorreção é complicação comum após a ressecção da aponeurose do levantador (40%) ou suspensão ao frontal (27,5%). Conclusões: As práticas atuais dos cirurgiões oculoplásticos espanhóis e latino-americanos para diagnóstico e tratamento de ptose da pálpebra superior foram relatadas. Os dados apresentados podem ser usados para comparar a abordagem dos cirurgiões com a de seus pares.

Estudo exploratório acerca da prevalência do alto risco para eventos coronários na população brasileira: evidências da Pesquisa Nacional de Saúde 2013 / Exploratory study on the prevalence of high risk for coronary events in the Brazilian population: evidence from National Health Survey 2013

Resumo Introdução: As doenças do aparelho circulatório representam a principal causa de adoecimento e mortes na população mundial. Objetivo: Estimar a prevalência de alto risco para evento coronário (ARC) e os fatores associados na população adulta brasileira. Método: Estudo transversal, com base nos dados da Pesquisa Nacional de Saúde 2013. Para os indivíduos classificados em ARC, segundo a primeira fase de estratificação da I Diretriz Brasileira de Prevenção Cardiovascular, avaliou-se a associação dessa condição com variáveis sociodemográficas, condição de saúde e hábitos e estilo de vida. A análise estatística foi realizada em três etapas: descritiva, bivariada e múltipla. Consideraram-se os pesos amostrais e o efeito de desenho do plano de amostragem complexo, utilizando-se da biblioteca survey do programa estatístico R, versão 3.2.2. Resultados: A prevalência de ARC na população brasileira foi de 11,06% (IC95% 10,83-11,29). Observou-se maior proporção de ARC com o avançar da idade, em indivíduos residentes no centro-sul, que autoavaliaram a saúde como ruim/muito ruim, ex-fumantes e hipertensos. Conclusões: A população brasileira apresentou alta prevalência de ARC e, assim, possui mais de 20% de risco de um evento coronário agudo nos próximos dez anos, caso medidas de prevenção e controle não sejam tomadas.

Abstract Background: Diseases of the circulatory system are the leading cause of illness and death in the world population. Objective: Estimate the prevalence of high risk for coronary events (HRC) and associated factors in the Brazilian adult population. Method: This is a cross-sectional study, based on data from the National Health Survey 2013. The association of this condition with sociodemographic, health condition, and habits and lifestyle was evaluated for individuals as in HRC, according to the first stratification phase of the I Brazilian Directive of Cardiovascular Prevention. Statistical analysis was performed in three stages: descriptive; bivariate; and multiple analysis. Sampling weights and design effect of the complex sampling plan were considered, using the survey library of the statistical program R, version 3.2.2. Results: The prevalence of HRC in the Brazilian population was 11.06% (95%CI 10.83-11.29). A higher prevalence of HRC was observed with advancing age, in individuals living in the Central-South, who self-rated their health as poor/very poor, former smokers, and individuals with systemic arterial hypertension. Conclusions: The Brazilian population presented a high prevalence of HRC and, thus, has a more than 20% risk of an acute coronary event in the next ten years, if prevention and control measures are not taken.

Prevalência e fatores associados a atividades que levam ao nervosismo no trabalho no Brasil: estudo com dados da Pesquisa Nacional de Saúde, 2013 / Prevalence and factors associated with activities that lead to nervousness at work in Brazil: study with data from the National Health Survey, 2013

Resumo Objetivos: descrever a prevalência de atividades que levam ao nervosismo e analisar os fatores associados a essa condição em trabalhadores brasileiros. Métodos: estudo transversal realizado com dados da Pesquisa Nacional de Saúde (PNS), edição de 2013. A variável dependente foi o envolvimento em atividades que levam ao nervosismo e as independentes foram características sociodemográficas, ocupacionais e situação de saúde. Empregou-se análise de regressão de Poisson com variância robusta. Resultados: participaram deste estudo 36.442 trabalhadores, 53,4% do sexo masculino. A prevalência de atividades que levam ao nervosismo no trabalho foi de 33,8% (Intervalo de Confiança de 95% [IC95%]: 33,2; 34,2). Na análise ajustada, raça/cor da pele preta (Razão de Prevalência [RP]: 0,84; IC95%: 0,77;0,92) e parda (RP:0,86; IC95%: 0,82;0,91), idade maior que 60 anos (RP:0,74; IC95%: 0,64;0,85) e trabalhar em ambientes abertos (RP: 0,82; IC95%: 0,77;0,87) foram significativamente associados a uma menor prevalência de atividades que levam ao nervosismo. Ruído (RP: 1,96; IC95%: 1,86;2,06), material radioativo (RP: 1,28; IC95%: 1,16;1,41), trabalho noturno (RP: 1,31; IC95%: 1,24; 1,38), idade de 30 a 39 anos (RP: 1,10; IC95%: 1,03;1,17) e depressão (RP: 1,36; IC95%: 1,26;1,47) associaram-se a uma maior probabilidade do desfecho. Conclusão: características sociodemográficas, ambientais e aspectos de saúde estão associados a atividades que levam ao nervosismo em trabalhadores brasileiros.

Abstract Objective: to describe the prevalence of activities leading to nervousness and analyze the factors associated with this condition in Brazilian workers. Methods: cross-sectional study using data from the National Health Survey (PNS) - 2013. The dependent variable was involvement in activities leading to nervousness, and the independent variables included sociodemographic, occupational, and health-related characteristics. We calculated the Poisson regression with robust variance. Results: 36,442 workers participated in this study, 53.4% male. The prevalence of activities leading to nervousness at work was 33.8% (95% of Confidence Interval [95%CI]: 33.2; 34.2). In the adjusted analysis, black (Prevalence Ratio [PR]: 0.84; 95%CI: 0.77;0.92) and mixed race (PR: 0.86; 95%CI: 0.82;0.91) individuals, aged over 60 years (PR: 0.74; 95% CI: 0.64;0.85), and those working in open environments (PR: 0.82; 95%CI: 0.77;0.87) were significantly associated with a lower prevalence of activities leading to nervousness.

Vasectomy reversal in China during the recent decade: insights from a multicenter retrospective investigation / 亚洲男科学杂志(英文版)

To date, there is little information about the demography of vasectomy reversal (VR) patients or the factors currently influencing VR effectiveness in China, especially after the universal two-child policy was released in 2015. In this research, demographic data and perioperative medical records of VR patients were extracted from seven major hospitals in different provinces or municipalities of China. Meanwhile, a telephone survey of the patients was conducted to collect follow-up information. Eventually, 448 VR cases from the past 13 years were included. The results were analyzed by stratified comparison to investigate factors that can influence postoperative vas deferens patency and pregnancy rate. Appropriately statistical methods were used, and all of the protocols were approved by the Ethics Committees of the institutes in this research. The results showed that the annual operation volume of VR quadrupled after the two-child policy was implemented. Nonmicrosurgery and a long duration of vasectomy were significantly associated with a lower patency rate. A follow-up survey showed that the general postoperative pregnancy rate was 27.2%. For female partners over the age of 35 years, the postoperative pregnancy rate showed a more severe decline, but only 35.5% of them had been given a fertility examination before their husbands' VR surgery. Our work revealed that more patients in China have been demanding VR in recent years. High-quality microsurgery and a short duration of vasectomy are crucial for restoring patency by VR. Clinical andrologists should perform a preoperative fertility evaluation of the patients' female partners.

Doenças crônicas e problemas de saúde de adolescentes: desigualdades segundo sexo / Chronic diseases and health conditions in adolescents: Sex inequalities

RESUMO Objetivo: Estimar as prevalências de doenças crônicas e problemas de saúde em adolescentes de Campinas (SP), observando as diferenças entre os sexos, por faixa etária. Métodos: Estudo em base populacional, com dados do inquérito de saúde ISACamp de 2014/15, cujas entrevistas com adolescentes totalizaram 1.022. Desses entrevistados, 517 eram meninos e 505, meninas; 492 encontravam-se na faixa de dez a 14 anos e 530 tinham entre 15 e 19 anos. As associações foram verificadas por meio do teste de χ² com ajuste de Rao Scott, e as razões de prevalência (RP) foram estimadas por meio de regressão múltipla de Poisson ajustadas por idade. Também foram feitas análises estratificadas por faixa etária. Resultados: As doenças respiratórias foram as mais prevalentes nos adolescentes como rinite (25,3%), sinusite (15,7%) e asma (10,9%). As queixas de saúde apresentaram-se elevadas, destacando-se as dores de cabeça (39,5%), problemas emocionais (34,5%), alergias (27,5%) e dores nas costas (21,3%). O número de adolescentes que apontaram ter três ou mais problemas de saúde mostrou-se acima de 22,0%. As meninas referiram maior número de problemas de saúde (três ou mais) do que os meninos (RP=2,27). Conclusão: O estudo demonstrou que os adolescentes apresentaram número expressivo de problemas de saúde, principalmente em relação às queixas, sinalizando que são necessários cuidados clínicos e políticas públicas direcionadas para o controle e prevenção desses agravos nesta faixa etária.

ABSTRACT Objective: To estimate the prevalence of chronic diseases and health conditions in adolescents from Campinas (São Paulo), investigating sex differences according to age group. Methods: This population-based study analyzed data from the ISACamp 2014/15 health survey, with a total of 1,022 adolescents interviewed. The interviewees consisted of 517 boys and 505 girls; 492 of them in the ten to 14 age group and 530 in the 15 to 19 age group. We verified the associations using the χ2 test with Rao Scott adjustment and estimated prevalence ratios (PR) with multiple Poisson regression adjusted for age. Analyses were also stratified by age group. Results: Respiratory diseases, such as rhinitis (25.3%), sinusitis (15.7%), and asthma (10.9%), were the most prevalent among adolescents. Health complaints were high, especially headaches (39.5%), emotional conditions (34.5%), allergies (27.5%), and back pain (21.3%). More than 22.0% of adolescents reported having three or more health conditions. Girls declared a higher number of health conditions (three or more) than boys (PR=2.27). Conclusion: The study showed that adolescents presented a significant number of health conditions, particularly regarding complaints, indicating the need for clinical care and public policies aimed at controlling and preventing these diseases in this age group.

There is no shortage, but inequality: demographic evolution of neurologists in Brazil (2010-2020) / Não há escassez, mas sim desigualdade: evolução demográfica de neurologistas no Brasil (2010-2020)

Abstract Background Neurology is a medical specialty that deals with prevalent diseases such as stroke, headache, epilepsy, and neurodegenerative diseases. Many countries, such as Brazil, struggle to provide neurological care for their populations, but the inadequacy and unequal distribution of the neurologist workforce are real challenges. Objective To analyze the demographic evolution of neurologists and the first-year Neurology residency positions in Brazil during the last decade (2010-2020) and the distribution imbalance between regions. Methods The demographic and geographic distribution of neurologists was calculated based on data extracted from the Brazilian Federal Medical Council reports, and the number of Neurology residency positions was based on the Brazilian National Commission of Medical Residency reports. Indicators of wealth were associated with demographic data. Results The number of neurologists per 100,000 population has increased since 2011, with a similar increase in the geographic distribution of neurologists. However, there was a marked inequality of distribution of neurologists through regions, with a gap between the Northern (lowest) and Southeastern (highest) regions. Furthermore, the imbalance of distribution of neurologists strongly correlated with social inequality. The number of Neurology residency positions increased, but with an imbalance between North and Southeast regions. Conclusions Brazil has advanced in providing neurologists. However, instead of a shortage, inequality between regions is the greatest challenge regarding the neurological workforce. The training of new neurologists is unequal between regions and occurs at a slower rate than needed. Neurologists, public health authorities, and patients should discuss solutions for these issues.

Resumo Antecedentes A Neurologia é uma especialidade médica que lida com doenças prevalentes, como acidente vascular cerebral, cefaleia, epilepsia e doenças neurodegenerativas. Muitos países, como o Brasil, se esforçam para oferecer assistência neurológica à população, mas a distribuição insuficiente e desigual da força de trabalho de neurologistas são desafios. Objetivo Analisar a evolução demográfica dos médicos neurologistas e das vagas de Programas de Residência Médica em Neurologia no Brasil durante a última década (2010-2020) e o desequilíbrio de distribuição entre as regiões. Métodos A distribuição demográfica e geográfica de neurologistas foi calculada com base nos dados extraídos de relatórios do Conselho Federal do Medicina do Brasil, e o número de vagas em Programas de Residência Médica em Neurologia foi extraído de dados da Comissão Nacional de Residência Médica. Os indicadores de riqueza foram associados aos dados demográficos. Resultados O número de neurologistas por 100.000 habitantes aumentou desde 2011, com um aumento similar na distribuição geográfica de neurologistas. Entretanto, houve uma nítida desigualdade na distribuição de neurologistas entre as regiões, com um hiato entre as regiões Norte e a Sudeste. Além disso, a desigualdade da distribuição de neurologistas se correlacionou fortemente com a desigualdade social. O número de vagas em Programas de Residência Médica aumentou, porém com desigualdade entre as regiões Norte e Sudeste. Conclusões O Brasil tem avançado na geração de neurologistas. Porém, ao invés de uma escassez, a desigualdade entre regiões é o maior desafio em relação à força de trabalho neurológica. O treino de novos neurologistas é desigual entre regiões e ocorre em um ritmo mais lento do que o necessário. Neurologistas, autoridades em saúde pública e pacientes devem discutir soluções para estes problemas.

Encuesta colombiana de neurología 2016-2020 / Colombian neurology survey 2016-2020

RESUMEN INTRODUCCIÓN: La práctica de la neurología como especialidad clínica es relativamente reciente en Colombia, a pesar de que esta área ha mostrado progresos académicos significativos; la información sociodemográfica es limitada. OBJETIVO: Describir las características sociodemográficas de los neurólogos laboralmente activos en Colombia. METODOLOGÍA: Estudio descriptivo en dos periodos. La información se obtuvo mediante encuestas autodiligenciadas a los asistentes al Congreso Nacional de Neurología del año 2016; la del 2020 se recolectó empleando cuestionarios en línea a través de formularios Google. RESULTADOS: Se contabilizaron 549 neurólogos laboralmente activos en el territorio colombiano. El análisis de las muestras 2016 y 2020 mostró que la mayor proporción de estos especialistas se concentraba en Bogotá (45,4 %), Medellín (13,4 %) y Cali (8,4 %), con una ocupación escasa en ciudades no capitales. La comparación de horas laborales e ingresos económicos al analizar 2016 y 2020 no mostró diferencias. El mayor tiempo de ejercicio se correlacionó con mayores ingresos, tanto en el 2016 (p < 0,001) como en el 2020 (p < 0,01). CONCLUSIONES: Excepto por el incremento en la población de nuevos neurólogos, las características socio-demográficas de los neurólogos en Colombia se mantienen sin variaciones al comparar los años 2016 y 2020.

ABSTRACT INTRODUCTION: Neurology practice is relatively recent in Colombia. Even though this area has shown significant academic advances, information regarding sociodemographic conditions is limited. OBJECTIVE: To describe sociodemographic characteristics of neurologists who are currently active in Colombia. METHODS: Descriptive study over two time periods. The information was obtained by means of self-administered surveys to the neurologists attending the neurology national congress in 2016. In 2020, data was collected by means of on-line questionnaires using google forms. RESULTS: The sample included 549 neurologists. The largest proportion of these specialists were located in Bogotá (45.4 %), Medellín (13.4 %) and Cali (8.4 %). After comparing working hours per week and income we did not identify differences between these 2 years. The time of work experience was correlated with economic income both in 2016 (p<0.001) as in 2020 (p<0.01). CONCLUSION: Except for increasing number of neurologists of recent graduation, the sociodemographic characteristics of Colombian neurologists remain stable when comparing 2016 and 2020.

Adaptación al sotobosque de una comunidad de palmas (Arecaceae) andinas desde la perspectiva de las tasas vitales / Adaptation to the undergrowth of a community of Andean palms (Arecaceae) from the vital rates perspective

Introducción: Las palmas tienen adaptaciones para prosperar en el entorno limitante del sotobosque, que se pueden examinar a partir del estudio de las tasas de supervivencia, crecimiento y fecundidad. Sin embargo, los estudios que abordan las estrategias de tasas vitales desarrolladas por una comunidad de palmas para habitar el sotobosque del bosque son escasos. Objetivo: Determinar y comparar las tasas vitales de supervivencia, crecimiento y fertilidad en una comunidad de palmas de sotobosque andino. Métodos: El estudio se realizó en el Parque Natural Chicaque, Colombia. En un área de 0.07 ha, donde se estudiaron las especies Chamaedorea linearis, C. pinnatifrons, Geonoma orbignyana y G. undata. Durante 2018 a 2019 se recolectaron datos correspondientes a supervivencia, crecimiento y fecundidad. Las tasas vitales se estimaron a partir de su relación con el tamaño de los individuos. Resultados: Se registraron un total de 597, 687, 453 y 690 individuos en 0.1 ha de C. linearis, C. pinnatifrons, G. orbignyana y G. undata, respectivamente. Las cuatro especies tuvieron una alta supervivencia de plántulas, bajas tasas de crecimiento en individuos sin tallo, baja producción de hojas, pocas hojas totales, una alta longevidad de las hojas, e inicio de la reproducción con un tallo de baja altura. No obstante, hubo diferencias entre las especies en las que G. orbignyana y C. pinnatifrons presentaron patrones comúnmente vistos en las palmas del sotobosque. Por el contrario, C. linearis y G. undata tienen estrategias de crecimiento mixtas para hacer frente a los espacios abiertos y las condiciones del sotobosque, ya que sus hojas y copas son más grandes, tienen mayores tasas de crecimiento del tallo y la reproducción comienza a mayor altura. En cuanto a los géneros, las Chamaedoreas tuvieron unas tasas de crecimiento y reproducción altas, pasando la mayor parte de su vida como adultos. Por su parte, las Geonomas priorizan la permanencia de los individuos, con sus ciclos de vida largos, tasas de crecimiento más bajas. Conclusiones: Las Chamaedoreas priorizan crecimiento y reproducción, mientras que las Geonomas priorizan la permanencia. Las condiciones limitantes del sotobosque parecen favorecer estas dos estrategias de crecimiento típicas de las especies estudiadas. Estos resultados pueden considerarse como un paso hacia el conocimiento de las estrategias de la coexistencia de las comunidades de palmeras en los bosques.

Introduction: Palms have adaptations to thrive in the limiting environment of the understory, which can be examined from studying their survival, growth and fecundity rates. However, studies that address the vital rates strategies developed by a community of palms to successfully inhabit the forest understory are scarce. Objective: To determine and compare the vital rates of survival, growth and fecundity in a community of Andean understory palms. Methods: The study was carried out in the Chicaque Natural Park, Colombia in an area occupying 0.07 ha, focused on the species Chamaedorea linearis, C. pinnatifrons, Geonoma orbignyana and G. undata. During 2018 and 2019, data corresponding to survival, growth and fecundity of these species were collected. The vital rates were estimated from their relationship with the size of the individuals. Results: A total of 597, 687, 453 and 690 individuals were registered in 0.1 ha of C. linearis, C. pinnatifrons, G. orbignyana and G. undata, respectively. The four species had high survival of seedlings, low growth rates in stemless individuals, low leaf production, few total leaves, a high longevity of the leaves and start of reproduction with low-height aerial stem. However, we found differences among species in which G. orbignyana and C. pinnatifrons demonstrated patterns commonly seen in understory palms. By contrast, C. linearis and G. undata had mixed growth strategies to cope with open spaces and understory conditions, as their leaves are larger, have larger stem growth rates and reproduction begins at a higher height. In terms of the genera, Chamaedoreas had fast growth and reproduction rates, spending most of their lives as adults. Meanwhile, Geonomas prioritizes the stasis of individuals, with its long-life cycles and lower growth rates. Conclusions: Chamaedoreas prioritizes growth and reproduction, while Geonomas prioritizes stasis. The limiting conditions of the understory seem to favor these two growth strategies in the species. These results can be considered as a step towards better understanding the strategies of a community of palms in the understory.
