Atividades educativas aos portadores de periodontite crônica: escuta e troca de saberes no autocuidado em saúde bucal

This research aimed at evaluating oral health education activities for Periodontitis carriers, emphasizing the motivation for self-care and understanding the cultural aspects involved. This was a qualitative and quantitative study. Based on the qualitative referential, 20 interviews were done, in which differences between scientific and popular explicative models of the health-illness process were verified, besides the increased knowledge and motivation in relation to the use of preventive measures and also the fails in the understanding of the chronic character of periodontitis, enhancing frustration and guilty feelings in the patients. Two groups were structured: intervention and control. The intervention group was submitted to clinical attendance and education activities, while the control group undergone the traditional clinical attendance only. The sample consisted of 51 participants of intervention group and 47 of control group. Structured interviews were conducted at the beginning and at the end of the treatment in order to evaluate the knowledge and motivation for self-care in both groups. For comparison between the previous and post moments in both groups, there were applied McNemar tests with a probability of p < 0.05. In intervention group there was an increase in knowledge related to the name, the causes and related factors of the disease (p < 0.05). In control group there wasn t a rise in the understanding of the diseases chronic character, unlike in intervention group. However, in what concerns self-care, a greatest frequency in medium and high scores was observed in both groups. By this study, it is conclude that there is a common sense knowledge about the importance of preventive techniques and poor oral health as causing periodontitis; clinical interventions for bearers of chronic Periodontitis do not add values to the patients, regarding the illness, its causes and its chronic character; popular beliefs stay in their imagination, and the patients have a increased motivational capacity for self-care

ANÁLISE COMPARATIVA DO CONHECIMENTO, ATITUDES E PRECONCEITOS DE UNIVERSITÁRIOS DOS CURSOS DE PEDAGOGIA, EDUCAÇÃO FÍSICA E MEDICINA EM RELAÇÃO À EPILEPSIA

Epilepsy is a chronic disorder of the central nervous system, most frequently characterized by abnormal electrical impulses in the brain. It is the oldest recorded neurological disease and has been surrounded by myths, mistaken beliefs and preconceptions. Three professionals work with epileptic patients on a daily basis: teachers, physical educators and physicians . This study aimed to analyze and compare the level of knowledge, preconceptions and attitudes of undergraduate students in the courses of Pedagogy, Physical Education and Medicine, future professionals who will deal with epileptic patients. This descriptive observational study was conducted with 286 university undergraduates of both sexes (women 99/34.6% and men 187/65.4%) from the first to fourth year of Pedagogy, Physical Education and Medicine courses at the Universidade Estadual Rio Grande do Norte (UERN), with mean age of 23 years. A validated and adapted 17-question questionnaire, divided into nine knowledge-based questions, five related to preconceptions and three on attitudes, was applied. Results allowed elaboration of a manuscript entitled Comparative Analysis of Knowledge, Attitude and Preconceptions in University Undergraduates of Pedagogy, Physical Education and Medicine Courses in Relation to Epilepsy. The findings of this article show that knowledge of epilepsy in the three groups is very satisfactory. The low level of preconception indicates that educational or clarifying information is being transmitted, albeit by television, a layman s information vehicle, which has undoubtedly contributed to reducing the stigma of epilepsy through educational information. Results also suggest a lack of knowledge on how to act during a seizure, especially in education professionals. Although there are limitations in our sample, the relevance and contribution of this study is to call attention to the importance and need for these future professionals to be informed and learn correct attitudes with respect to epilepsy during their academic formation. This is essential at a time when the disease is being brought out of the shadows. This research was supported by the Office of the Dean of Teaching, and Deans of Pedagogy, Physical Education and Medicine at UERN. The research was made possible by the multidisciplinary interaction among a physical educator, child neurologist and statistician, all contributing to achieving the aims set out here

Atividade anticoagulante, antioxidante e antitumoral de heterofucanas da alga Dictyopteris delicatula (Lamouroux, 1809)

In the present study, six families of sulfated polysaccharides were obtained from seaweed Dictyopteris delicatula (Lamouroux, 1809) and their anticoagulant, antioxidant and antitumor activities were evaluated. All fractions showed anticoagulant activity on aPTT assay, but not on PT assay. Fractions also exhibited total antioxidant activity, superoxide radical scavenging capacity and ferric chelating property. Thus, six fractions (F0.5v, F0.7v, F1.0v, F1.3v, F1.5v e F2.0v) we obtained by proteolytic digestion, followed by acetone fractionation and molecular sieving on Sephadex G-100. Chemical analyses demonstrated that all polysaccharides contain heterofucans composed mainly of fucose, xylose, glucose, galactose, uronic acid, and sulfate. Any fractions changed the PT. However, all fractions were able on double the aPPT on a dose-dependent manner. The heterofucans F0.7v and F1.0v showed low anticoagulant activity while F1.5v presented the most prominent anticoagulant activity .When compared to Clexane®, a low molecular weight heparin, at same concentration F1.5v presented similar anticoagulant activity. The fucans F0.5v and F0.7v at 1.0 mg/mL showed high ferric chelating activity (~45%), whereas fucans F1.3v (0.5 mg/mL) showed considerable reducing power, about 53.2% of the activity of vitamin C. The fucan F1.5v presented the most prominent anticoagulant activity. The best antiproliferative activity was found with fucans F1.3v and F0.7v. However, F1.3v activity was much higher than F0.7v inhibiting almost 100% of HeLa cell proliferation. These fucans have been selected for further studies on structural characterization as well as in vivo experiments, which are already in progress

Ensaio clínico duplo-cego controlado e randômico, comparando a eficácia da Clofazimina com a Cloroquina, no tratamento das lesões cutâneas do Lúpus Eritematoso Sistêmico

PURPOSE: To evaluate the capacity of clofazimine (CFZ) to control cutaneous activity of systemic lupus erythematosus (SLE), compared with chloroquine diphosphate (CDP). METHODS: A prospective, randomized, controlled, double blind clinical trial was carried out in thirty-three patients with SLE and cutaneous lesions (malar rash and/or discoid lupus and/or subacute cutaneous lupus), after approval by the respective Ethics Committee. Sixteen patients received clofazimine - 100mg/day (CFZ group) and 17 received chloroquine diphosphate - 250mg/day (CDP group), during six months. Both groups applied broad-spectrum sunscreens twice a day. The dose of prednisone was kept stable during the study. Cutaneous lesions were evaluated by 2 blinded observers and photographed at baseline and at months 1, 2, 4 and 6. RESULTS: Thirty-three patients began and 27 completed the 6 months of treatment. The groups were homogeneous and comparable in terms of demographic and clinical characteristics. Five CFZ-patients and one CDP-patients dropped out due to severe flare of disease requiring other treatment. At the end of the study, 12 CFZ-patients (75%) and 14 CDP-patients (82,4%) presented complete or near-complete remission of skin lesions; intention-to-treat analysis showed no significant difference in the response rates between groups. Side effects in both groups were frequent, but patients didn t have to discontinue the drugs. CONCLUSIONS: Clofazimine and chloroquine were effective in controlling cutaneous lesions in SLE patients

Biodistribuição do pertecnetato de sódio após cirurgia do Switch Duodenal

The biliopancretic diversion with duodenal switch is one of the mixing techniques used in the treatment of morbid obesity. The duodenal switch reduces the stomach capacity and leaves only 50-100 cm of small intestine for nutrition and absorption. The surgery produces hormonal, structural and biochemical changes, which can influence on the result of scintigraphic examinations in operated patients. With the objective of evaluate the postoperative biodistribution of sodium pertechnetate (Na99mTcO4) in brain, thyroid, heart, lung, liver, spleen, kidney, stomach, duodenum, pancreas, small intestine, bladder, muscle and bone of Wistar rats. The rats were randomly allocated into 3 groups of 7 rats each: the duodenal switch group (DS), the control group (C) and the sham group (S). They were operated under anesthesia and aseptic technique. In the tenth postoperative day, 0.1mL of sodium pertechnetate was injected via orbital plexus. After 30 min the animals were killed with overdose of anesthetic and samples of liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, bone and brain were harvested, washed with saline and weighed. The detention of radioactivity was made using the automatic Gamma Counter Wizard, PerkinElmer and the percentage of activity per gram of tissue (%ATI/g) was calculated. There was no early or late mortality in either rats groups. The values of percent radioactivity per gram of tissue (%ATI/g), showed no significant difference in liver, stomach, small bowel, duodenum, kidney, heart, bladder, bone and brain, when compared the DS rats with sham and controls rats. A postoperative significant increase in mean %ATI/g levels was observed in spleen, pancreas and muscle in group DS rats, as compared to group S and C rats (p<0.05). In the lung there was an increase and in thyroid a decrease in mean %ATI/g of DS rats, when compared to sham rats (p>0.05). In conclusion, the biliopancreatic diversion with duodenal switch in rats modified the biodistribution of sodium pertechnetate in thyroid, lung, pancreas, spleen and muscle. The study had the participation of the departments and laboratories researches, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research

Estilo de vida individual de universitários jovens com excesso de peso da Universidade Católica de Murcia-Espanha

Individual lifestyle includes health and risk behaviors that can altar health status. Excess weight is a public health problem of modern civilization and there is an estimated mean prevalence of 45% in European countries. In Spain, the Murcia Region is an area of high morbidity and mortality from cardiovascular disorders. In this study we assess the differences in health and risk behaviors in ove/weight and normal weight undergraduates at the Universidad Católica San Antonio de Murcia (UCAM). Methods: Transversal design of parallel groups (overweight - cases and normal weight - control) , formed using the anthropometric technique. A questionnaire applied to a sample of 471 undergraduates of either sex, between the ages of 18 and 29 years, enrolled in 4 bachelor degree courses (ADE, CA, PER, PUB) at UCAM. We performed a standardized measurement of body mass (weight in kg), height (in meters) using a Seca® scale with calibrated stadiometer, waist and hip circumferences (in cm) with an inelastic tape and skinfolds thickness (triceps and subscapular in mm) with a Holtain® caliper, to calculate body mass index (BMI), waist-to-hip ratio (WHR) and the sum of skinfolds (SSF). We applied a lifestyle questionnaire about alcohol and tobacco consumption, knowledge and behaviors related to health indicators (arterial pressure and cholesterol), diet and physical activity. The information was collected in April and May, 2001 at the UCAM laboratory of Applied Nutrition. Statistical analysis: analysis of independent groups, contingency tables that reveal which qualitativa variables show differences and associations between the groups, Pearson's chi-square,and a significance levei of p < 0.05 followed by a residual analysis (1.96). Descriptive statistics (mean and standard deviation) were used to establish the two groups: case and contrai with 65 men and 26 women each who had BMI < 25 kg/m2. Results: A total of 65 of the men assessed (14%) and 26 (6%) of the women were overweight. Mean body mass index of the case group was 27. 78 ±: 2.83 kg/m2 in the men and 26.26 ± 1.37 kg/m2 in the women, while contrai group men had mean BMI of 22.36 ± 1.72 kg/m2, while for the women it was 20.76 ±: 2.13 kg/m2. The self-declared values of weight and height were underestimated, but with high accuracy, sensitivity and specificity. Thus, these can be used to calculate the BMI of overweight Spanish undergraduates. Regular vigorous physical activity was observed only in normal weight men. The analysis showed the following significant differences for the qualitativa variables of the two groups. The contrai group was interested in arterial hypertension, believed that they were not overweight, that they had no abdominal fat, and had not considered controlling 'fatty food consumption. Those who thought of controlling it sometimes, did so without professional help. However, part of the overweight group believed that they were overweight and had abdominal fat between average and considerable, had often or always considered controlling fatty foods and had often or always tried to control consumption with the help of professionals. They had always thought of engaging in physical activities, unlike the normal weight individuals. Nearly all (95%) of the overweight undergraduates and most (75%) of the normal weight group reported that they sometimes or always controlled fatty food ingestion. Mean physical activity was nearly twice as high in the summer than in the winter. Conclusions: The overweight undergraduates in this sample displayed a lifestyle with a greater number of healthy behaviors when compared to normal weight individuals

Diferenças de gênero na produção de associações livres de palavras através do ciclo sono-vigília

Although several studies, have shown differences in cognitive performance between men and women, it not yet known whether these differences occur in tasks involving free association of words (WA). Studies across the sleep-wake cycle (SWC) suggest that rapid eye movement sleep (REM) favors semantic flexibility, in comparison with pre-sleep waking (Pre-WK), slow-wave sleep (SWS) and post-sleep waking (Post-WK). The present work has two aims: (1) to evaluate the semantic distances of word pairs produced by AP, comparing men and women, (2) to evaluate semantic distance in word pairs produced by free association across the SWC in young adults of both sexes. To achieve aim (1), we applied a task of WA in 68 adult volunteers during waking (52 women and 16 men). The WA task consisted of writing the first word that came to mind after viewing another word offered as a stimulus (root Word). To achieve aim (2), we performed polysomnography to identify specific stages of the SWC. The experimental subjects were then awakened (if they were asleep) and were immediately given a WA task. The task was administered to 2 groups of 10 subjects each (G1 and G2). G1 subjects were stimulated with the same set of root words after waking from various states of SWC, while G2 subjects received sets of different root words at each state of the SWC. In the absence of a Portuguese corpus suitable for the measurement of semantic distances, the words collected in our experiments were translated to English, and semantically quantified within a systematic and representative corpus of that language (Wordnet). This procedure removed the polysemies typical of Portuguese, but preserved the semantic macrostructure common to both languages. During waking, we found that semantic distances are significantly lower in WA produced by women, in comparison with the distances observed in men. Through the SWC, there were no statistically significant differences in G1. In G2 women, we detected a significant increase of semantic distances upon being awakened from SWS. In contrast, G2 men showed a significant increase in semantic distances upon being awakened from REM. The results of the first experiment are consistent with the notion that women have a more concrete reasoning than men. The results of the second experiment indicate that men awakened from REM present more flexibility in word association than when being awakened from other states. In contrast, women showed more flexible word association after being awakened from SWS, in compared with other states. The results indicate that the cognitive flexibility attributed to different states of the SWC shows gender dependency

STRESS: um diagnóstico dos policiais militares da cidade de Natal Brasil

Objectives: The purpose of the current study was to diagnose military police officers in Natal, Brazil as to the level and phase of stress in which they find themselves and the prevalent symptomatology (physical or mental). Methodology: Descriptive, crosscut study that investigated a sample of 264 individuals taken from a population of 3,193 military police officers of the Capital Police Command (CPC) in Natal, Brazil. The data were collected using the Lipp Stress Symptoms for Adults Inventory LSSI, and analyzed by tabulations, percentage calculations, t-test for proportions and Pearson s chi-squared test for associations between stress, symptomatology and military rank. Data collection was between June/2004 and January/2005. Results: It was found that 52.6% of the officers had symptoms of stress and 47.4% symptomatology of stress. This was distributed across all ranks, especially mid and upper-level officers as well as corporals and privates, with predominance in the resistance phase (36%) and a prevalence of psychological symptoms (76%). The only variable investigated that was related to stress was gender (P = 0.0337). Conclusions: It was concluded that there is stress among all ranks of military police officers in Natal, Brazil, especially mid and upper-level officers, corporals and privates, with a prevalence of psychological symptoms, low levels of physical symptoms and predominance in the resistance phase. It seems that stress levels do not differ significantly from those found in Brazilian men and women and do not indicate a situation of chronic fatigue

Biodistribuição do pertecnetato de sódio (Na99mTcO4) em ratos submetidos à ressecção extensa de intestino delgado

Massive resection of the small intestine results in short bowel syndrome with anti-absorptive effect and repercussions on the metabolism. Morphologic and functional evaluation may be necessary in order to control wrapped organs. Scintigraphy an examination with little invading and no biologic damage can be used. The purpose were to assess the biodistribution of sodium pertecnetate in organs of rats subjected to massive resection of the small intestine, the intestinal adaptation of the remnant intestinal mucosa and weight curve evaluation in the postoperative period. Twenty-one Wistar rats were randomly allocated into three groups (n = 7). The operated group named short bowel (SB) after anesthetized was subjected to massive resection of the small intestine; the control group (C), and sham group (SHAM). On the 30th postoperative day, 0.l mL of sodium pertechnetate was injected into the venous orbital plexus. After 30 minutes, the rats were killed with an overdose of anesthetic, and fragments of the liver, spleen, pancreas, stomach, duodenum, small intestine, thyroid, lung, heart, kidney, bladder, muscle, femur and brain were harvested. The percentage of radioactivity per gram of tissue (%ATI/g) was determined using Gama Counter WizardTM 1470, PerkinElmer to all samples. Biopsies of 3 cm remaining jejunum were removed to histological analyses. Analysis of variance (ANOVA) and the Tukey test for multiple comparisons were used, considering p<0.05 as significant. The study had the participation of some departments and laboratories, as Nucleus of Experimental Surgery, Department of Surgery, Laboratory of Radiobiology, Department of Pathology and Service of Nuclear Medicine, certifying the character of a multidisciplinary research. The results were no significant differences in %ATI/g of the sodium pertechnetate in the organs of the groups studied (p>0.05). An increase in the weight of the SB rats was observed after the second postoperative week. The jejunal mucosal thickness of the SB rats was significantly greater than that of C and sham rats (p<0.05. The biodistribution of sodium pertechnetate was not affected by massive intestinal resection in rats. An adaptive response by the intestinal mucosa probably contributed to the reversion of weight loss and the biodistribution of sodium pertechnetate was not affected by the surgery

Ação da cafeína sobre o rendimento esportivo de ciclistas em condições de calor e umidade

Objetivo: Verificar a ação da cafeína no tempo de rendimento, a taxa de esforço percebido (RPE), os níveis plasmáticos de glicose, sódio e potássio, a temperatura timpânica (Tt), o peso corporal (PC), freqüência cardíaca (FC) e concentração urinária da cafeína com a ingestão de doses de 5 e 9 mg/kg de cafeína e placebo, em provas ciclísticas sob condições de alto risco térmico. Métodos: Foram estudados 8 ciclistas treinados e aclimatizados em 3 provas de 45 km utilizando o modelo experimental e duplo-cego com randomização intra-sujeitos. Resultados: Não foram observadas diferenças significativas entre as variáveis avaliadas, entretanto o tempo de rendimento e a RPE foram menores com as doses de 5 e 9 mg/kg de cafeína que com a dose placebo. Conclusões: Estes dados indicam que as condições de calor e umidade podem ser suficientes para mascarar o benefício ergogênico da cafeína, entretanto deve-se considerar que a cafeína pode exercer influencia sobre a percepção subjetiva de esforço podendo levar à redução dos sinais de fadiga durante o exercício e conseqüente melhora do desempenho esportivo

Tempo livre de lazer e composição corporal de escolares do meio-oeste catarinense

The aim of this study was to investigate the relationship between free time for leisure and body composition of students in the crucial ninth year. (N = 228) of towns in the Midwest catarinense. We used the Adolescent Behavior Questionnaire of Santa Catarina (COMPAC) to assess lifestyle, considering that Active schoolchildren during the week, accumulated 300 or more minutes of moderate or vigorous physical activity (MVPA). Were used the time to 2 hours or more / day to determine the time of excessive use of TV and computer video game. To analyze body composition were used two criteria: the Body Mass Index (BMI) and sum of skinfolds (EDC). It was observed a proportion of 67.3% of girls and 68.7% of boys assets and more than 98% of students were using excessive TV time, computer and video game. In the classification by EDC, most of the boys showed great or low levels of body composition, while more than half of girls were classified at higher levels. As for BMI, most boys and girls had not overweight. Significant difference in the comparison of total minutes per week of MVPA reported between the groups, the second criterion of EDC and BMI for girls but not for BMI in boys. It is concluded that students with higher accumulation in minutes of MVPA showed better body composition indicators, but no significant difference was found when compared active groups with inactive, according to criteria used.

Liofilização como ferramenta de preservação de sêmen humano

Liofilização é um método alternativo de preservação de espermatozóide, com vantagens sobre o criopreservado pelo baixo custo de armazenamento, facilidade no transporte pela não necessidade de containers e baixas taxas de contaminação. Esse estudo foi realizado no intuito e testar a eficácia de 5 açúcares na proteção do material cromossômico (DNA) de espermatozoides humanos liofilizados após reidratação. Para isso foram utilizados espermatozoides de indivíduos classificados como normozooespérmicos segundo OMS. Em eppendorfs foram colocados 1ml de sêmen que foram diluídos (1:1) em 1 ml de solução de Glicose, Lactose, Maltose, Manitol e Sorbitol, separadamente, nas concentrações 0.2M, 0.4M, 0.5M e 0.6M. Essas amostras foram analisadas em duas fases a primeira após congelamento observando a porcentagem de células com danos de membrana e outra análise após a liofilização, utilizando o Teste Cometa para detectar as taxas de fragmentação de DNA dos espermatozoides recuperadas após reidratação. O processo de liofilização de espermatozoides não foi capaz de recuperar a motilidade dos mesmos, mas foi capaz de manter 62.30 ± 13.76% de membrana plasmática intacta na presença de 0.6M manitol. As substâncias que melhor preservaram o DNA dessas células foram 0.2 lactose, 0.2M e 0.6M manitol e sorbitol, com apenas 4% de danos ao DNA. Esses resultados sugerem uma boa proteção ao DNA de espermatozoides humanos liofilizados, mas ainda requer testes adicionais para avaliar a fertilização e estudos que garantam a viabilidade da prole

Consequências da colectomia associada à hepatectomia no metabolismo hepático e na forma e função de hemácias em ratos

This study investigated the influence of partial colectomy associated with hepatectomy on the biodistribution of the 99mTc-phytate, on metabolic parameters, as well as labeling and morphology of red blood cells. Wistar rats were distributed into three groups (each with 6), nominated as colectomy, colectomy+hepatectomy and sham. In the 30th postoperative day all rats were injected with 99mTc-phytate 0.1mL i.v. (radioactivity 0.66 MBq). After 15 minutes, liver sample was harvested and weighed. Percentage radioactivity per gram of tissue (%ATI/g) was determined using an automatic gamma-counter. Serum AST, ALT, alkaline phosphatase and red blood cells labeling were determined. The liver %ATI/g and red blood cells labeling were lower in colectomy and colectomy+hepatectomy rats than in sham rats (p <0.05), and no difference was detected comparing the colectomy and colectomy+hepatectomy groups. Red blood cells morphology did not differ among groups. Serum levels of AST, ALT and alkaline fosfatase were significantly higher in colectomy+hepatectomy than in colectomy rats (p<0.001). Hepatectomy associated with colectomy lowered the uptake of radiopharmaceutical in liver and in red blood cells in rats, coinciding with changes in liver enzymatic activity

Análise de parâmetros da função reprodutiva masculina após perda ponderal induzida pela cirurgia bariátrica

Introdução: A obesidade e suas formas extremas como a forma mórbida, vem assumindo preocupação nos sistemas de saúde pública e é atualmente considerado um dos mais importantes agravos de saúde no mundo desenvolvido. Acarreta repercussões em várias partes do corpo, com potencial para interferir negativamente também na função reprodutiva, recentemente sendo mais estudado na população masculina. Objetivo: avaliar parâmetros hormonais e seminais da função reprodutiva em um grupo de homens obesos mórbidos, antes e após 6 meses da perda de peso induzida pela cirurgia bariátrica. Métodos: Inicialmente, de uma amostra de 36 pacientes com idade entre 18 e 40 anos e índice de massa corporal (IMC) ≥40 Kg/m2, apenas 1 caso foi excluído por ser portador de hiperprolactinoma e outros 24 pacientes não completaram todo o protocolo de avaliação laboratorial solicitada. Um total de apenas 11 pacientes completou o protocolo. Todos foram previamente avaliados por uma equipe multidisciplinar. O grupo selecionado foi submetido a avaliação seminal e dosagens hormonais de testosterona total(TT), FSH e LH. Os parâmetros foram reavaliados após 6 meses de realização da cirurgia pela técnica de Y-em-Roux, para análise dos efeitos da perda de peso sobre os parâmetros da função reprodutiva. Resultados: No grupo selecionado ao estudo, os exames pré-operatórios mostraram um grupo heterogêneo de resultados. Após seis meses do tratamento cirúrgico, a perda ponderal foi significativa no grupo analisado, com redução do IMC de mediana 46 Kg/m2para mediana de 36 Kg/m2(p=0,03). Em relação ao perfil hormonal, houve elevação significativa do nível sérico de TT com mediana de 187ng/ml no período pré-operatório para 457 ng/ml (p=0,02) no período pós-operatório. Entre os períodos pré e pós-operatório, não foram observadas alterações significantes do FSH (2,70 mIU/ml para 3,31 mIU/ml, p=0,79), LH (4,82 mIU/ml para 3,00mIU/ml, p=0,39), concentração espermática (38milhões/ml para 31milhões/ml, p=0,88) e motilidade A+B (50% para 50%, p=0,89).Conclusão: A redução ponderal decorrente da cirurgia em obesos mórbidos parece levar a uma elevação dos níveis de testosterona total, sem alterações nas demais provas de avaliação reprodutiva. Estudos adicionais com casuística maior e múltiplos parâmetros são necessários para esclarecimento definitivo do impacto da obesidade e da perda de peso induzida pela cirurgia sobre a função reprodutiva masculina
