Moderating role of 1-minute abdominal test in the relationship between cardiometabolic risk factors and adiponectin concentration in adolescents.

BACKGROUND: Adiponectin is an anti-inflammatory cytokine secreted by adipose tissue, has been associated with adiposity and cardiometabolic risk, and has controversial results with muscular fitness. The aim of this study was to analyze the interaction of 1-minute abdominal test in the relationship between adiposity, body composition, cardiometabolic risk and adiponectin concentration in adolescents. METHODS: This is a cross-sectional study conducted with 62 adolescents of both sexes, aged 11 to 16 years, approved by the Ethics Committee of Research in Humans (CAEE: 62963916.0.0000.5223). Body mass, height, abdominal circumference (AC), waist circumference (WC), fat mass (FM), fat-free mass (FFM), high density lipoprotein (HDL-c), low density lipoprotein (LDL-c), triglycerides (TG), adiponectin, systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean blood pressure (MBP), 1-minute abdominal test (ABD) were measured. Body mass index (BMI), z-score BMI (BMI-z), triponderal mass index (TMI), and waist-to-height ratio (WHtR) were calculated. The macro PROCESS for SPSS v.24.0 was used for moderation analyses, with linear regression models. RESULTS: Inverse interactions were found for adiposity (BMI, BMI-z, TMI, AC, WC, WHtR), body composition (FM, FFM) and CMRF (SBP, DBP, MBP, TG) versus 1-minute abdominal test with adiponectin concentration, demonstrating that abdominal test is a moderator in these relationships. CONCLUSION: We conclude that 1-minute abdominal test may play an important role in the relationship between obesity and cardiometabolic risk. We found that muscular fitness can confer a protective effect on adolescents with high levels of abdominal test.

Prevalence of skin lesions in a sample of Brazilian patients with inflammatory bowel disease.

OBJECTIVE: Inflammatory bowel diseases may have extra intestinal manifestations such as those affecting the skin. This study aimed to study skin manifestations in a cohort of Brazilian patients with inflammatory bowel diseases. METHODS: Epidemiological and clinical data were obtained through a cross-sectional study of 70 inflammatory bowel diseases patients and a control group comprising 50 healthy individuals. All patients were subjected to dermatological examination and photography of skin lesions. RESULTS: Out of the 70 inflammatory bowel diseases patients, 50 had ulcerative colitis and 20 had Crohn's disease. Skin lesions occurred in 95.7% of the inflammatory bowel diseases patients and in 88% of individuals in the control group (p=0.001). Alopecia (p<0.0001), xerosis (p=0.03), striae (p=0.02), and acne (p=0.04) were more common in inflammatory bowel diseases patients than in the control group. Alopecia was more frequent in females (p=0.01) than in males. Two male patients, one with ulcerative colitis and the other with Crohn's disease, had pyoderma gangrenosum. Erythema nodosum was not observed in both groups. CONCLUSION: There was a high prevalence of skin lesions in the Brazilian inflammatory bowel diseases patients. Additionally, alopecia, xerosis, striae, and acne were more common in patients with inflammatory bowel diseases than in those in the control group.

Moderation of Physical Activity between Cardiometabolic Risk and Adiponectin in Adolescents.

The aims of the study were to examine the moderating role of physical activity in the relationship between cardiometabolic risk factors and adiponectin concentration in adolescents. This is a cross-sectional study conducted with 96 adolescents of both sexes, between 11 and 17 years old. Body mass, height, fat mass (FM), fat-free mass, systolic blood pressure, diastolic blood pressure, high density lipoprotein, low density lipoprotein (LDL-c), triglycerides, insulin, adiponectin, C-reactive protein, and level of physical activity (energy expenditure questionnaire) were measured. Body mass index (BMI), triponderal mass index (TMI), homeostasis model to assessment insulin resistance (HOMA-IR), and quantitative insulin sensitivity check index (QUICKI) were calculated. Macro-PROCESS for SPSS was used for moderation analyses. Direct interactions were found for BMI, TMI, FM, insulin, and HOMA-IR and inverse for LDL-c, and QUICKI. Protection against cardiometabolic risk was found when the PA-coeff was completed above 1.57 coeff (BMI), 1.62 coeff (TMI), 1.55 coeff (FM), 1.41 coeff (LDL-c)1.60 coeff (insulin), 1.59 coeff (HOMA-IR) and 1.35 coeff (QUICKI). We conclude that physical activity was a moderator in the relationship with adiposity, insulin resistance and sensitivity, LDL-c, and adiponectin. In this context, we evidenced a relevant clinical impact on the health of adolescents, demonstrating the interaction between anthropometrics variables and physical activity.

Effects and individual response of continuous and interval training on adiponectin concentration, cardiometabolic risk factors, and physical fitness in overweight adolescents.

This study aimed to evaluate the effect and individual responsiveness after 12 weeks of high-intensity interval training (HIIT) and moderate-intensity of continuous training (MICT) on adiponectin, cardiometabolic risk factors and physical fitness in overweight adolescents. This study was participated by 52 adolescents, both sexes, 11 and 16 years old, separated into HIIT (n = 13), MICT (n = 15), and control group (CG, n = 24). Body mass, height, waist circumference (WC), fat mass (FM), fat-free mass (FFM), blood pressure, high-density lipoprotein (HDL-c), low-density lipoprotein (LDL-c), triglycerides, glucose, insulin, adiponectin, and C-reactive protein (CRP) were evaluated. Body mass index z-score (BMI-z), waist-to-height ratio (WHtR), insulin resistance, and insulin sensitivity were calculated. Resting heart rate (HRrest), peak oxygen consumption (VO2peak), right handgrip strength (HGS-right), left handgrip strength (HGS-left), and abdominal resistance (ABD) was evaluated. HIIT session lasted around 35 min and MICT of 60 min of exercises on stationary bicycle, three times a weekday for 12 weeks. ANOVA, effect size, and prevalence of responders were used for statistical analysis. HIIT reduced BMI-z, WHtR, LDL-c, and CRP, while increased of physical fitness. MICT reduced HDL-c, while increased of physical fitness. CG reduced FM, HDL-c, and CRP, while increased FFM and HRrest. Frequencies of respondents in HIIT were observed for CRP, VO2peak, HGS-right, and HGS-left. Frequencies of respondents in MICT were observed for CRP and HGS-right. Frequencies of no-respondents in CG were observed for WC, WHtR, CRP, HRrest, and ABD.  Conclusion: Interventions with exercises were effective to adiposity, metabolic health, and physical fitness improvements. Individual responses were observed in inflammatory process and physical fitness, important changes in overweight adolescent's therapy.  Trial registration number and date of registration: This study was registered with the Brazilian Registry of Clinical Trials (REBEC), the number RBR-6343y7, date of registration May 3, 2017. What is Known: • Effect of regular physical exercise positively affects overweight, comorbidities, and metabolic diseases, recommended mainly for children and adolescents. What is New: • Due to the great inter-individual variability, the same stimulus can provide different responses; adolescents who benefit from the stimulus are considered responsive. • Intervention of HIIT and MICT did not alter the concentrations of adiponectin; however, the adolescents presented responsiveness to the inflammatory process and physical fitness.

Perfil clínico e epidemiológico dos acidentes por Lepidópteros, do gênero Lonomia, atendidos no CIATox/PR, 2015-2019 / Clinical and epidemiological profile of accidents caused by Lepidoptera, of the Lonomia genus, assisted at CIATox/PR

Introdução: Os acidentes por lepidópteros são agravos de interesse à saúde pública e a avaliação de suas características pode contribuir para melhorar sua assistência e prevenção. Este estudo analisou o perfil epidemiológico dos acidentes por lagartas do gênero Lonomia no Paraná. Métodos: Trata-se de estudo retrospectivo de base secundária realizado no Centro de Informação e Assistência Toxicológica do Paraná (CIATox/PR), em Curitiba, no período de 2015 a 2019. A análise foi realizada por estatística descritiva e Teste do qui-quadrado (p<0,05). Resultados: A amostra foi composta de 84 acidentes por Lonomia sp. com predomínio em adultos (45,2%), do sexo masculino (59,5%), e de lesões em membros superiores (84,5%). O contato com as lagartas ocorreram na área peridomiciliar da residência habitual do paciente (72,6%), na zona rural (64,27%) da macrorregião oeste paranaense (38,1%). O verão concentrou 71,4% dos casos, seguido por primavera e outono com 14,3% dos casos, respectivamente, sem registros no inverno. As manifestações clínicas mais frequentes foram dor local (62,4%), equimose (34,1%), eritema (34,1%), edema e queimação (17,6% cada). A classificação leve mostrou uma redução entre a fase inicial e a final do processo, ao contrário da moderada e grave, que tiveram aumento significativo de casos (p=0,006). O RNI (Relação Normatizada Internacional) foi incoagulável em 16,7% dos pacientes. Dois casos apresentaram piora do quadro clínico, sendo uma evolução para acidente vascular cerebral hemorrágico e um óbito. Discussão: Maior número de casos registrados na zona rural, tanto na residência habitual ou ambiente laboral, se dá pelo maior contato com o habitat das lagartas como árvores frutíferas e grandes monoculturas, o que também explica o fato de a macrorregião oeste ter o maior número de casos registrados. O aumento do desmatamento, incentivos à construção de parques públicos e plantio de árvores frutíferas na zona urbana são hipóteses para o aumento de casos nessa área. Percebeu-se que manifestações clínicas discretas podem ter uma evolução desfavorável, quando comparado estadiamento inicial e final. A realização do RNI se mostrou de grande importância na mudança de estadiamento, conduta terapêutica e diagnóstico. Conclusão: O perfil encontrado foi de acidentes por Lonomia sp. com sazonalidade no verão, em homens adultos da zona rural com gravidade moderada. Esses achados revelam a importância do diagnóstico e tratamento precoce frente às diferentes possibilidades de evolução clínica desses acidentes. É fundamental estimular estratégias para identificação da lagarta, notificação dos casos e medidas preventivas permanentes para reduzir riscos e agravos (AU).

Introduction: Lonomic accidents are of public health interest and the evaluation of their characteristics can contribute to the improvement of their attention and prevention. This study analyzed the epidemiological profile of Lonomic accidents in Paraná. Methods: This study is a retrospective secondary-based study carried out at the Center of Toxicologic Information and Assistance of Paraná (CIATox/PR), in Curitiba, from 2015 to 2019. Descriptive statistical analyses were performed using the Chi-square test (p<0.05). Results: The sample consisted of 84 accidents with Lonomia sp., showing greater occurrences among adults (45.2%) of the male gender (59.5%) and injuries on the upper limbs (84.5%). Contact with the worm occurred mainly in the patient's usual residence (72.6%), in the rural area (64.27%), and in Paraná's West macro-region (38.1%). Most cases were registered in the summer (71.4%), followed by spring and autumn (14.3%), and no accidents were registered in winter. The most frequent clinical manifestations were local pain (62.3%), ecchymosis (34.1%), erythema (34.1%), swelling and burning (17.6% each). The mild classification showed a reduction between the initial and the final phase of the process, as opposed to moderate and severe classifications, which showed a significant increase in the percentage (p=0,006). The INR was incoagulable in 16.7% of patients. Two cases showed progressive worsening, one of them evolved into a hemorrhagic stroke and one death. Discussion: The greater number of incidents registered in the rural area, both in the patients' usual residence and work environment, can be due to the greater contact with the caterpillar's natural habits, such as fruit trees and large monocultures. This also explains the larger number of registered incidents in the western macro-region. The increased deforestation, the construction of public parks, and the planting of fruit trees in the urban area are hypotheses for the increase of reported cases in this area. When comparing initial and final staging, it was noticed that discrete clinical manifestations could have an unfavorable evolution. The INR request proved to be of great importance in the management, diagnosis and change of staging of the patient. Conclusion:The epidemiological profile was of Lonomia sp. accidents happening in summer in adult males in the rural area with moderate severity. These findings reveal the importance of early diagnosis and treatment in view of these accidents' different possibilities of clinical evolution. It is essential to encourage strategies for identifying the caterpillar, reporting cases, and implementing permanent preventive measures to reduce risks and complications (AU).

Esta pesquisa buscou analisar os casos de intoxicações por organofosforados e carbamatos, presentes em agrotóxicos e pesticidas, registrados na base de dados do Centro de Informação e Assistência Toxicológica do Paraná (CIATox/PR). Trata-se de estudo retrospectivo em que foram avaliadas variáveis sociodemográficas e clínicas relacionadas à intoxicação, à forma de exposição, à causa e ao desfecho. Para a análise estatística foram utilizados testes de Kolmogorov-Smirnov, Shapiro-Wilk, Qui-Quadrado e Teste Exato de Fisher, considerando p<0,05. A amostra foi composta por 426 casos, sendo 218 (51,2%) mulheres. O principal agente foi raticida clandestino em 278 (65,2%) pacientes. A principal circunstância das intoxicações foi tentativa de suicídio com 293 (68,8%) casos. Houve predominância de exposição via oral (89,9%) e zona urbana em 349 (81,9%) casos, a maioria considerados leves (52,6%) e assistidos em serviços médicos (66,4%). Cerca de 327 (76,8%) indivíduos apresentavam manifestações clínicas. O tempo decorrido entre a exposição e o contato com o CIATox/PR foi maior nos casos considerados graves (p= 0,041). A atropina foi utilizada em 94 (49%) pacientes intoxicados por carbamatos, em 31 (33,3%) por organofosforados e em 84 (59,6%) por outros inibidores da colinesterase não especificados. Duas mulheres e um adolescente apresentaram desfecho fatal, tendo em comum a ingesta intencional de "chumbinho". A casuística predominante nesta série histórica foi paciente do sexo feminino, faixa etária adulta, residente na região metropolitana, exposta a agrotóxico por via oral, sintomática, classificada como gravidade leve, sem necessidade de atropina, contudo ocorreram três casos com desfecho para o óbito.

This research aimed to analyze the cases of poisoning by organophosphates and carbamates, present in agrochemicals and pesticides, registered in the database of the Information and Toxicological Assistance Center of Paraná (CIATox/PR). This is a retrospective study in which sociodemographic and clinical variables related to intoxication, form of exposure, cause and outcome were evaluated.

The sample consisted of 426 cases, 218 (51.2%) of which were women. The main agent was clandestine rodenticide in 278 (65.2%) patients. The main circumstance of intoxication was a suicide attempt with 293 (68.8%) cases. There was a predominance of oral exposure (89.9%) and urban areas in 349 (81.9%) cases, most considered mild (52.6%) and assisted in medical services (66.4%). About 327 (76.8%) individuals had clinical manifestations. The time elapsed between exposure and contact with CIATox/PR was longer in cases considered severe (p=0.041). Atropine was used in 94 (49%) patients intoxicated by carbamates, in 31 (33.3%) by organophosphates and in 84 (59.6%) by other unspecified cholinesterase inhibitors. Two women and one teenager had a fatal outcome, having in common the intentional ingestion of "chumbinho". The predominant casuistry in this historical series was a female patient, adult age, living in the metropolitan region, exposed to pesticides orally, symptomatic, classified as mild severity, without the need for atropine, however, there were three cases with an outcome of death.

Percepção de barreiras à prática de atividades físicas por pacientes diabéticos tipo 2 / Perception of barriers to the practice of physical activities by type 2 diabetic patients

O diabete melito está entre as principais causas de mortalidade no mundo e pode ser agravada pela inatividade física. O objetivo deste estudo descritivo transversal foi identificar as barreiras percebidas para a prática de atividade física sob a perspectiva dae pacientes diabéticos tipo 2. Participaram 220 pacientes (111 mulheres e 109 homens), com média de idade de 62,9 anos. Foram coletados índice de massa corporal, dados sociodemográficos e informações relacionadas ao histórico de doenças preexistentes. Para a análise das barreiras percebidas para a prática de atividades físicas, utilizou-se um questionário estruturado e validado para a população adulta brasileira proposto por Martins&Petroski. As barreiras foram analisadas individualmente e agrupadas em domínios ambiental, comportamental, físico e social. Em conclusão, as barreiras percebidas foram a falta de interesse (38,6%), cansaço físico (32,3%) e jornada de trabalho extensa (26,3%) e, assim, medidas devem ser adotadas visando minimizar os efeitos dessas barreiras e promover a atenção primária à saúde à essa população

Diabetes is among the leading causes of mortality in the world and can be aggravated by physical inactivity. This descriptive cross-sectional study aimed to identify the perceived barriers to the practice of physical activity from the perspective of type 2 diabetic patients. 220 diabetic patients participated in the research (111 women and 109 men), with a mean age of 62.9 years. Body mass index, sociodemographic data and information related to the history of preexisting diseases were collected. For the analysis of perceived barriers to the practice of physical activities, a structured and validated questionnaire for the Brazilian adult population proposed by Martins&Petroski was used. Barriers were analyzed individually and grouped into environmental, behavioral, physical and social domains. In conclusion, the main barriers perceived were lack of interest (38.6%), physical fatigue (32.3%) and long working hours (26.3%) and, them, measures should be taken to minimize the effects of these barriers, in order to promote primary health care in this population

THE MANAGEMENT OF DERMATITIS HERPETIFORMIS BY THE GASTROENTEROLOGIST. A SERIES OF CASES.

BACKGROUND: Dermatitis herpetiformis (DH) is considered a skin celiac disease (CD). The individuals can be seen by primary care professionals or by dermatologists that could refer the patient to a gastroenterologist. OBJECTIVE: The study aimed to investigate the clinical profile of patients diagnosed with DH and referred to a gastroenterologist and evaluate the treatment response. METHODS: We retrospectively studied patients with DH referred to the same gastroenterologist at a private office in Curitiba, Brazil, between January 2010 to December 2019. We included adult patients with a confirmed DH diagnosis. Symptoms, clinical signs, laboratory and histological data, as well as treatment response, were collected. RESULTS: Thirty-three patients were studied (60.6% women, mean age at diagnosis 40.8±12.61 years). The median delay for DH diagnosis was four years. Skin involvement was mild in 33.3%, moderate in 18.2%, and severe in 48.5%. The more frequent gastrointestinal complaints were abdominal distension (78.8%), flatulence (75.7%), and gastroesophageal reflux (51.5%). Depression and anxiety were observed in 81.8% and anemia in 51.1%. A higher prevalence of bone disorders was associated with higher age at DH diagnosis (P=0.035). Duodenal biopsy showed changes in all patients. Improvement after treatment only with a gluten-free diet (GFD) plus dapsone was verified in 81.2%. CONCLUSION: Patients with DH referred to a gastroenterologist showed a high frequency of gluten intolerance and systemic complaints. Duodenal histological alterations were found in all the cases. The treatment based on GFD plus dapsone was effective in most patients.

RESUMO CONTEXTO: A dermatite herpetiforme (DH) é considerada como a doença celíaca (DC) da pele. Os pacientes podem ser atendidos por profissionais do atendimento primário ou por dermatologistas que podem encaminhar o paciente a um gastroenterologista. OBJETIVO: Os objetivos do estudo foram investigar o perfil clínico dos pacientes com diagnóstico de DH encaminhados a um gastroenterologista e avaliar a resposta ao tratamento. MÉTODOS: Foram investigados retrospectivamente pacientes com DH encaminhados ao mesmo gastroenterologista em consultório particular em Curitiba, Brasil, entre janeiro de 2010 a dezembro de 2019. Foram incluídos pacientes adultos com diagnóstico confirmado de DH. Dados sobre sintomas e sinais clínicos, dados laboratoriais, histológicos e resposta ao tratamento foram coletados. RESULTADOS: Foram estudados 33 pacientes (60,6% mulheres, média de idade 40,8±12,61 anos). O atraso médio para o diagnóstico de DH foi de 4 anos. O envolvimento cutâneo foi considerado leve em 33,3%, moderado em 18,2% e grave em 48,5%. As queixas gastrointestinais mais frequentes foram distensão abdominal (78,8%), flatulência (75,7%) e refluxo gastroesofágico (51,5%). Depressão e ansiedade foram observadas em 81,8% e anemia em 51,1%. Maior prevalência de alterações ósseas foi associada à maior idade ao diagnóstico de DH (P=0,035). A biópsia duodenal mostrou alterações em todos os pacientes. A melhora após o tratamento apenas com dieta sem glúten e/ou dapsona foi verificada em 81,2%. CONCLUSÃO: Pacientes com DH encaminhados ao gastroenterologista apresentaram alta frequência de queixas gastrointestinais e sistêmicas. Alterações histológicas duodenais foram encontradas em todos os casos. O tratamento à base de dieta sem glúten e/ou dapsona foi eficaz na maioria dos pacientes.

Intoxicações por inibidores das colinesterases em mulheres / Poisonings by cholinesterases inhibitors in women

Organofosforados e carbamatos são produtos muito utilizados na agropecuária, que têm, em comum, a inibição da enzima acetilcolinesterase, causando impactos na saúde humana. O objetivo deste estudo foi avaliar aspectos epidemiológicos e clínicos das intoxicações agudas por organofosforados e carbamatos em mulheres. Tratase de estudo retrospectivo, transversal e descritivo, no qual foram analisados 218 casos de intoxicações agudas. Foram avaliadas variáveis clínicas, sociodemográficas e ocupacionais. Em conclusão, os dados demostraram intoxicações de gravidade leve a moderada por pesticidas nas mulheres, com registro de dois casos fatais. Efeitos crônicos podem aparecer em pessoas expostas a esses compostos. Medidas educativas e preventivas no manejo e comércio dessas substâncias devem diminuir o número de intoxicações e agravos à saúde da população.

Organophosphates and carbamates are products widely used in agriculture, both of this two substances work in the same way, through the inhibition of the enzyme acetylcholinesterase, and both also cause impacts on human health. The goal of this study was to evaluate the epidemiological and clinical aspects of acute poisoning by organophosphates and carbamates in women. This is a descriptive, cross-sectional, retrospective study in which 218 cases of acute poisoning were analyzed. Clinical, sociodemographic and occupational variables were included. In conclusion, the data demonstrated mild to moderate severity of pesticide poisoning in women, with two deaths reported. Chronic effects can appear in people exposed to these substances. Educational and preventive measures on the handling and sale of these substances can contribute to reducing the number of poisonings and health problems in the population.

Percepção de saúde pelo estudante de medicina: atividade física, imagem corporal e qualidade de vida / Student's perception of health: physical activity, body image and quality of life

Racional: A prática regular de atividade física é fundamental para promoção de estilo de vida saudável. Objetivo: Investigar a associação entre nível de atividade física e qualidade de vida dos acadêmicos de medicina de uma instituição de ensino privada. Métodos: Foram empregados: 1) questionário para avaliação sociodemográfica (gênero, idade, cor/raça/etnia, estado civil, história de tabagismo, período do curso, peso, estatura, índice de massa corporal, percepção da imagem corporal, motivos e barreiras à prática de atividade física, percepção da saúde); 2) Questionário Internacional de Atividade Física (IPAQ) versão curta para verificar prática de atividade física; e 3) Questionário WHOQOL-bref traduzido para o português para averiguar qualidade de vida. Resultados: A amostra foi composta por 208 estudantes de medicina (115 mulheres e 93 homens) na faixa etária média de 21,9 anos, fisicamente ativos (42,7%) ou muito ativos (18,7%). Houve diferença no IMC (p<0,01) e na percepção da imagem corporal (p<0,05) entre os gêneros. Os principais motivos para a prática de exercício físico foram satisfação pessoal, estética e perda de peso com diferença entre os gêneros (p<0,05). Não se detectou diferença na comparação entre nível de atividade física (IPAQ) e qualidade de vida (WHOQOL-bref) que foi classificada de regular a boa (p<0,05). Falta de tempo e preguiça foram os obstáculos mais frequentes à prática diária de exercícios físicos. Conclusão: Os estudantes apresentaram boa percepção da saúde; entretanto, independente do gênero, faz-se necessário estratégias para melhor administração do tempo e investimentos na adoção de estilo de vida mais ativo.

Background: The regular practice of a physical activity is essential to promote a healthy lifestyle. Objective: To investigate the association between physical activity level and quality of life of medical students from a private educational institution. Methods: The following were used: 1) questionnaire for sociodemographic assessment (gender, age, color/race/ethnicity, marital status, smoking history, course period, weight, height, body mass index, body image perception, reasons and barriers to the practice of physical activity, health perception); 2) International Physical Activity Questionnaire (IPAQ) short version to verify physical activity practice; and 3) WHOQOL-bref questionnaire translated into Portuguese to assess the quality of life. Results: The sample consisted of 208 medical students (115 women and 93 men) with an average age of 21.9 years, physically active (42.7%) or very active (18.7%). There were differences in BMI (p<0.01) and in-body image perception (p<0.05) between genders. The main reasons for the practice of physical exercise were personal satisfaction, aesthetics, and weight loss with a difference between genders (p<0.05). No difference was detected in the comparison between the level of physical activity (IPAQ) and quality of life (WHOQOL-bref), which was classified as fair to good (p<0.05). Lack of time and laziness were the most frequent obstacles to daily physical exercise. Conclusion: Students had a good perception of health; however, regardless of gender, strategies for better time management and investments in adopting a more active lifestyle are needed.

Conhecimento das mulheres sobre a terapia de reposição hormonal / Women's knowledge about hormone replacement therapy

Climatério é período de transição hormonal da mulher, com manifestações genitais e extragenitais que requerem ou não tratamento. Este estudo transversal analisou o conhecimento básico de mulheres de Curitiba-PR entre 45 e 60 anos sobre terapia de reposição hormonal através de questionário autoaplicado. Das 623 mulheres participantes a minoria fez ou fazia uso da terapia de reposição hormonal, sendo sintomas prevalentes dessa fase fogachos, distúrbio do sono, alteração do humor e diminuição da libido. Mais de 80% delas acreditavam que terapia de reposição hormonal pode melhorar qualidade de vida. No entanto, muitas disseram ter medo de iniciar esse tipo de tratamento. Maioria das entrevistadas foram orientadas sobre a menopausa, porém apenas uma parte delas foi instruída sobre benefícios e riscos da terapia. Esses dados corroboram a premissa de que ainda faltam orientações e medidas voltadas para o cuidado integral das mulheres no climatério

The climateric is a biological transition phase of the woman's life, being accompanied by genital and extra-genital manifestations whose symptons may, or may not, require treatment. The present transversal study intends to analyze the basic knowledge of the women between 45 and 60 years old about the hormone replacement therapy through a self-administered questionnaire. It has been observed that only few women have used or use hormone replacement therapy and that the most prevalent symptoms on this phase are hot flushes, sleep disturbance, mood changes and decreased libido. More than 80% of the interviewees believe that the hormone replacement therapy can improve life quality. However, many reported being afraid to initiate such treatment. The majority of the interviewees have been previously oriented about the menopause, but only a part of them have been warned about the benefits and risks of the said therapy. These data corroborate the premise that there is a lack of guidance and measures aimed at the integral care of women in the climateric

Survival analysis of children and adolescents with melanoma.

OBJECTIVES: to analyze the survival in juvenile melanoma. METHODS: retrospective study conducted by hospital record review and cancer records of patients aged 0 to 19 years, with histologically proven melanoma and treated between 1997 and 2017 at the Erasto Gaertner Hospital in Curitiba-PR. RESULTS: the sample comprised 24 patients, female (62.5%), mean 14.14 ± 4.72 years old, with head and neck melanoma (37.5%), chest (25%) and extremities. (20.8%). Signs and symptoms at diagnosis were increased lesion size (25%), bleeding (20.8%) and pruritus (16.6%). There was a Breslow II and IV index and Clark IV level, with a statistical tendency between Breslow IV and death (p = 0.127), and significance between Clark V and death (p = 0.067). Nine (37.5%) patients had metastases, six (25%) with distant metastases died (p = 0.001), five were girls (20.8%). Surgery was the standard treatment and chemotherapy the most used adjuvant (37.5%). The average time between diagnosis and death was 1.3 ± 1.2 years and survival were 3.7 ± 3.2 years. CONCLUSION: there was a delay in diagnosis, high morbidity and mortality and average survival less than five years.

Validation of equations to estimate the peak oxygen uptake in adolescents from 20 metres shuttle run test.

This study aimed to develop new prediction models from directly determined peak of oxygen uptake (VO2peak) in adolescents using 20-metre shuttle run test (20 m-SR) and to compare the new models with previously published equations. This study included 148 adolescents (43% girls), aged 13.37 ± 1.84 years old. Adolescents were randomly assigned to validation (n = 91) and cross-validation (n = 57) groups. VO2peak was measured using a gas analyser in both maximal exercise tests in the laboratory as well as by 20 m-SR. The multiple linear regression method was applied to develop the models using BMI, BMI-z score and body fat percentage (%FM). The proposed models presented better predictive performance (R2 = 75.6% to 78.9%) and a lower absolute percentage error (%error = 10.51 to 11.78%) than the previously published equations (R2 = 38.8% to 69.1%; %error = 13.13% to 21.54%). The Model with BMI-z was the best fit equation in girls, and the model with BMI-z and %FM in boys. Therefore, it is recommended that the equations developed in the present study be used in future research and projects in the school environment to estimate VO2peak in adolescents by the 20 m-SR test.

Epidemiological and clinical assessment of patients undergoing Videolaparoscopic Cholecystectomy at a Curitiba teaching hospital. / Análise do perfil clínico epidemiológico dos pacientes submetidos a Colecistectomia Videolaparoscópica em um hospital de ensino de Curitiba.

OBJECTIVE: to assess clinical and epidemiological factors of patients undergoing video cholecystectomy at the Hospital da Cruz Vermelha do Paraná, Curitiba unit, operated from September 2016 to September 2018, as well as the influence of comorbidities, sex and advanced age on the postoperative prognosis, while in the hospital. METHODS: Analytic retrospective study. The analyzed variables were obtained by the review of medical records. Statistical analyses were performed considering the significance level p < 0.05. RESULTS: 389 patients, of whom 265 were women and 124 men, were included. The mean age was 51.5 years, 58.8% of the patients were diagnosed with at least one comorbidity, and 74.6% were overweight or obese. The incidence of intraoperative complications was 1.3%, postoperative 3.8% and, mortality, 0.3%. Some risk factors were identified as worse postoperative prognosis, such as Diabetes Mellitus, hypertension, presence of one or more comorbidities and mainly, advanced age, which was related to longer hospitalization times (p < 0,001), need of intensive therapy (p < 0,001), conversion to open surgery (p = 0,003) and postoperative complications (p < 0,001). Furthermore, the male sex was predictive of longer hospitalization times (p = 0,003) and need of intensive therapy (p = 0,01). CONCLUSION: the presence of comorbidities, male sex, and advanced age are predictive factors of bad prognosis for patients undergoing video laparoscopic cholecystectomy.

OBJETIVO: Analisar o perfil clínico e epidemiológico de pacientes submetidos a colecistectomia por vídeo no Hospital da Cruz Vermelha do Paraná, unidade de Curitiba, operados no período de setembro de 2016 a setembro de 2018, assim como a influência de comorbidades, sexo e idade avançada no prognóstico pós-operatório, durante o mesmo internamento. MÉTODOS: Estudo retrospectivo analítico, com dados coletados por revisão de prontuários. Análises estatísticas realizadas, considerando nível de significância p < 0,05. RESULTADOS: 389 casos foram incluídos, sendo 265 mulheres e 124 homens. A média de idade foi de 51,5 anos, 58,8% dos pacientes eram portadores de pelo menos uma comorbidade e 74,6% dos doentes tinham sobrepeso ou eram obesos. A incidência de complicações intraoperatórias foi de 1,3%, pós-operatórias de 3,8% e, a mortalidade, de 0,3%. Foram identificados fatores clínicos relacionados a pior prognóstico pós-operatório, como DM, HAS, presença de uma ou mais comorbidades e, destacadamente, idade avançada, que relacionou-se com maior tempo de internamento (p < 0,001), necessidade de UTI (p < 0,001), conversão para operação aberta (p = 0,003) e risco de complicações pós-operatórias (p < 0,001). Além disso, o sexo masculino foi preditivo para maior tempo de internamento (p = 0,003) e maior necessidade de UTI (p = 0,01). CONCLUSÃO: o perfil clínico-epidemiológico corresponde àquele exposto na literatura e a presença de comorbidades, o sexo masculino e a idade avançada são fatores preditivos de mau prognóstico na evolução pós-operatória de pacientes submetidos a colecistectomia videolaparoscópica.
