Use of fractional exhaled nitric oxide as a potential predictor of bronchodilator response.

Nitric oxide (NO) is an important product of eosinophilic metabolism, and its increase is associated with bronchial remodeling and airway hyperresponsiveness. Fractional exhaled NO (FENO) in the expired air of patients with suspected or diagnosed asthma has been used as a marker for eosinophilic inflammation. This cohort study included asthmatic patients classified under steps 3, 4, or 5 of the global strategy for asthma management and prevention. In the morning of the same day, all patients underwent blood collection for eosinophil counts, followed by FENO measurement and spirometry. We considered 2 groups based on the bronchodilation (BD) response on spirometry (>10% of FVC or FEV1): positive (BD+) and negative (BD-). Differences between the 2 groups were analyzed for demographic features, FENO values, and predictive correlations between FENO and BD. Both groups of patients showed an increase in the eosinophil count (BD+, P = .03; BD-, P = .04) and FENO values (P = .015 for both) with an increase in the asthma severity from step 3 to step 5 of the global strategy for asthma management and prevention. The correlations of FENO and eosinophils as well as FENO values and BD + were 0.127 (95% confidence interval,-0.269 to -0.486) and 0.696 (95% confidence interval, 0.246-0.899; P = .007), respectively. Measuring FENO levels may be useful for identifying patients with BD+.

Trends in food and beverage purchases in informal, mixed, and formal food outlets in Mexico: ENIGH 1994-2020.

Background: The retail food environment in Mexico is characterized by the co-existence of both, formal and informal food outlets. Yet, the contribution of these outlets to food purchases over time has not been documented. Understanding the longitudinal trends where Mexican households purchase their foods is critical for the development of future food retail policies. Methods: We used data from Mexico's National Income and Expenditure Survey from 1994 to 2020. We categorized food outlets as formal (supermarkets, chain convenience stores, restaurants), informal (street markets, street vendors, acquaintances), and mixed (fiscally regulated or not. i.e., small neighborhood stores, specialty stores, public markets). We calculated the proportion of food and beverage purchases by food outlet for each survey for the overall sample and stratified by education level and urbanicity. Results: In 1994, the highest proportion of food purchases was from mixed outlets, represented by specialty and small neighborhood stores (53.7%), and public markets (15.9%), followed by informal outlets (street vendors and street markets) with 12.3%, and formal outlets from which supermarkets accounted for 9.6%. Over time, specialty and small neighborhood stores increased 4.7 percentage points (p.p.), while public markets decreased 7.5 p.p. Street vendors and street markets decreased 1.6 p.p., and increased 0.5 p.p. for supermarkets. Convenience stores contributed 0.5% at baseline and increased to 1.3% by 2020. Purchases at specialty stores mostly increased in higher socioeconomic levels (13.2 p.p.) and metropolitan cities (8.7 p.p.) while public markets decreased the most in rural households and lower socioeconomic levels (6.0 p.p. & 5.3 p.p.). Supermarkets and chain convenience stores increased the most in rural localities and small cities. Conclusion: In conclusion, we observed an increase in food purchases from the formal sector, nonetheless, the mixed sector remains the predominant food source in Mexico, especially small-neighborhood stores. This is concerning, since these outlets are mostly supplied by food industries. Further, the decrease in purchases from public markets could imply a reduction in the consumption of fresh produce. In order to develop retail food environment policies in Mexico, the historical and predominant role of the mixed sector in food purchases needs to be acknowledged.

Comparison of High-Intensity Interval Training to Moderate-Intensity Continuous Training for Functioning and Quality of Life in Survivors of COVID-19 (COVIDEX): Protocol for a Randomized Controlled Trial.

OBJECTIVE: The purpose of this study was to compare high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) for feasibility, safety, adherence, and short- and long-term efficacy in improving functioning and health-related quality of life in survivors of coronavirus disease 2019 (COVID-19). METHODS: COVIDEX is a two-pronged, parallel-group, randomized controlled trial with an 8-week training intervention. The study participants will be 94 patients aged >18 years, admitted to a specialized post-COVID center. Participants will be randomized to HIIT (4 × 4 minutes of high-intensity work periods at 85% to 90% of peak heart rate) and MICT (47 minutes at 70% to 75% peak heart rate) groups for biweekly sessions for 8 weeks. The participants will undergo 2 phases of supervised training (phases 1 and 2) of 4 weeks each, in a public, specialized, post-COVID center. In phase 1, we will assess and compare the feasibility, acceptability, and short-term efficacy of HIIT and MICT intervention. In phase 2, the long-term efficacy of HIIT and MICT will be assessed and compared regarding function and health-related quality of life. To prevent any expectation bias, all study participants and assessors will be blinded to the study hypotheses. Group allocation will be masked during the analysis. All statistical analyses will be conducted following intention-to-treat principles. IMPACT: This study is the first randomized controlled trial that will compare the feasibility, safety, adherence, and efficacy of the HIIT and MICT intervention programs in this population. The findings will potentially provide important information and assist in clinical decision making on exercise to optimize the benefits of clinical health care in survivors of COVID-19.

Metabolic disorders and post-acute hospitalization in black/mixed-race patients with long COVID in Brazil: A cross-sectional analysis.

BACKGROUND: Although low-middle income countries have been disproportionately affected by the COVID-19 pandemic, there is scarce information about the impact of long COVID on their population. This study aimed to evaluate long COVID symptomatology, complications (hospital readmission and metabolic disorders), and main clinical features that impact Quality of Life (QoL). METHODS: This cross-sectional study provides a detailed clinical and laboratory picture of individuals who presented residual symptoms after mild to severe acute COVID-19. Between Aug-2020 to Sep-2021, long COVID patients were evaluated in a reference center for long COVID in Bahia State, Brazil. The EQ-5D-5L questionnaire accessed QoL. RESULTS: A total of 1164 (52 ±13.4 years, 57% female, 88% black/mixed-race) were evaluated 2.3 [IQR = 1.6-3.7] months after mild (n = 351, 30.2%), moderate (338, 29.0%) or severe (475, 40.8%) acute illness. Dyspnea (790, 67.9%), fatigue (738, 63.5%), and chest pain (525, 42.9%) were the most frequent residual symptoms regardless of acute severity, affecting the QoL of 88.9% of patients (n/N-826/925), mainly the domains of anxiety/depression and pain/discomfort. High levels of HbA1c were detected for 175 out of 664 patients (26.6%), 40% of them without a previous diagnosis of diabetes mellitus. Of note, hospital admission one-to-three months after the acute phase of disease was required for 51 (4.4%) patients. CONCLUSION: In this majority-black/mixed-race population, long COVID was associated with post-acute hospitalization, newly diagnosed diabetes mellitus, and decreased QoL, particularly in women and regardless of disease severity of acute infection, suggesting important implications for health care system.

Nanoencapsulation of buriti oil (Mauritia flexuosa L.f.) in porcine gelatin enhances the antioxidant potential and improves the effect on the antibiotic activity modulation.

The present study evaluated the cytotoxicity, antioxidant potential, and antimicrobial effect on the antibiotic activity modulation of gelatin nanoparticles containing buriti oil (OPG). The cytotoxicity analysis was performed on Chinese Hamster Ovary Cells (CHO) using a MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] test. The antioxidant potential of buriti oil and OPG was determined by total antioxidant capacity, reducing power, and the ABTS (2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid) test. The modulating antimicrobial activity was evaluated by determining the minimum inhibitory concentration (MIC) concentration against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, gentamicin and norflaxacillin. The nanoformulation of OPG did not show a cytotoxic effect on CHO cells and had a higher antioxidant potential than free buriti oil (p<0.05). The combination of antibiotics with free buriti oil and OPG was more efficient in inhibiting E. coli and P. aeruginosa than isolated norfloxacillin and gentamicin (p<0.05). Regarding the inhibition of S. aureus, OPG in combination with norfloxacillin reduced MIC by 50%. Nanoencapsulation was a viable alternative to enhance functionality and adding commercial value to buriti oil.

Multimorbidity associated with anxiety symptomatology in post-COVID patients.

The COVID-19 pandemic hit individuals with chronic conditions the hardest. It is known that anxiety symptoms are frequent in post-COVID conditions. We want to examine whether multimorbidity is associated with anxiety in post-COVID patients. We reported descriptive statistics from 389 post-COVID patients and perform a linear regression with anxiety symptoms measured using the Hospital Anxiety and Depression (HAD) scale. For each extra chronic condition, there was a mean increase of 0.11 in the HAD-anxiety score. However, there was a reduction for age and being male. These findings can potentially help policy-makers better organize post-COVID health services and improve patients care.

Accuracy of surrogate methods to estimate skeletal muscle mass in non-dialysis dependent patients with chronic kidney disease and in kidney transplant recipients.

BACKGROUND & AIMS: Bioelectrical impedance analysis (BIA) and anthropometric predictive equations have been proposed to estimate whole-body (SMM) and appendicular skeletal muscle mass (ASM) as surrogate for dual energy X-ray absorptiometry (DXA) in distinct population groups. However, their accuracy in estimating body composition in non-dialysis dependent patients with chronic kidney disease (NDD-CKD) and kidney transplant recipients (KTR) is unknown. The aim of this study was to investigate the accuracy and reproducibility of BIA and anthropometric predictive equations in estimating SMM and ASM compared to DXA, in NDD-CKD patients and KTR. METHODS: A cross-sectional study including adult NDD-CKD patients and KTR, with body mass index (BMI) ≥18.5 kg/m2. ASM and estimated SMM were evaluated by DXA, BIA (Janssen, Kyle and MacDonald equations) and anthropometry (Lee and Baumgartner equations). Low muscle mass (LowMM) was defined according to cutoffs proposed by guidelines for ASM, ASM/height2 and ASM/BMI. The best performing equation as surrogate for DXA, considering both groups of studied patients, was defined based in the highest Lin's concordance correlation coefficient (CCC) value, the lowest Bland-Altman bias (<1.5 kg) combined with the narrowest upper and lower limits of agreement (LoA), and the highest Cohen's kappa values for the low muscle mass diagnosis. RESULTS: Studied groups comprised NDD-CKD patients (n = 321: males = 55.1%; 65.4 ± 13.1 years; eGFR = 28.8 ± 12.7 ml/min) and KTR (n = 200: males = 57.7%; 47.5 ± 11.3 years; eGFR = 54.7 ± 20.7 ml/min). In both groups, the predictive equations presenting the best accuracy compared to DXA were SMM-BIA-Janssen (NDD-CKD patients: CCC = 0.88, 95%CI = 0.83-0.92; bias = 0.0 kg; KTR: CCC = 0.89, 95%CI = 0.86-0.92, bias = -1.2 kg) and ASM-BIA-Kyle (NDD-CKD patients: CCC = 0.87, 95%CI = 0.82-0.90, bias = 0.7 kg; KTR: CCC = 0.89, 95%CI = 0.86-0.92, bias = -0.8 kg). In NDD-CKD patients and KTR, LowMM frequency was similar according to ASM-BIA-Kyle versus ASM-DXA. The reproducibility and inter-agreement to diagnose LowMM using ASM/height2 and ASM/BMI estimated by BIA-Kyle equation versus DXA was moderate (kappa: 0.41-0.60), in both groups. Whereas female patients showed higher inter-agreement (AUC>80%) when ASM/BMI index was used, male patients presented higher AUC (70-74%; slightly <80%) for ASM/height2 index. CONCLUSIONS: The predictive equations with best performance to assess muscle mass in both NDD-CKD patients and KTR was SMM-BIA by Janssen and ASM-BIA by Kyle. The reproducibility to diagnose low muscle mass, comparing BIA with DXA, was high using ASM/BMI in females and ASM/height2 in males in both groups.

Association between changes in body fat distribution, biochemical profile, time of HIV diagnosis, and antiretroviral treatment in adults living with and without virus infection.

OBJECTIVES: Individuals living with HIV seem to be more prone to changes in the redistribution of body fat, characterized as lipodystrophy, which may occur in conjunction with metabolic diseases. In the present study, such impacts were assessed in adults with and without HIV and associated with the time of virus diagnosis and treatment with antiretroviral. METHODS: A cross-sectional study with 123 adults, in which 87 had HIV and 36 without HIV, of both sexes, in outpatient follow-up at the Specialized Care Service (SAE) in Macaé-RJ. The following were made: 1) Alteration in body fat distribution, measured by anthropometric parameters and self-reported lipodystrophy; 2) Biochemical profile; 3) Association between HIV diagnosis time and antiretroviral treatment. RESULTS: 54.47% (n = 67) males, 45.52% (n = 56) females, mean age 37 years. Of these 87 were people living with HIV, 29% (n = 25) had self-reported lipodystrophy, mean time of virus infection, and antiretroviral treatment (5.80 ± 4.56 and 5.14 ± 3.82 years), respectively. Patients with self-reported lipodystrophy had a greater change in body fat distribution between 3-6 years of HIV diagnosis and a negative cholesterol profile. The antiretroviral treatment time influenced total cholesterol and triglycerides, even for patients without self-reported lipodystrophy, with a further nine years under treatment. CONCLUSION: In this study, the negative cholesterol profile was mainly related to antiretroviral treatment time, even for patients without self-reported lipodystrophy, and changes in body fat distribution, measured by anthropometry, was especially associated with time for HIV infection in those with lipodystrophy self-reported.

RESUMO OBJETIVOS Indivíduos vivendo com HIV parecem mais propensos às alterações na redistribuição da gordura corporal, caracterizada como lipodistrofia, podendo acontecer em conjunto com as metabólicas. No presente estudo avaliaram-se tais impactos em adultos com e sem HIV e se associou ao tempo de diagnóstico do vírus e tratamento com antirretroviral. MÉTODOS Estudo tipo transversal, com 123 adultos, no qual 87 tinham HIV e 36 sem HIV, de ambos os sexos, em seguimento ambulatorial no Serviço de Atendimento Especializado (SAE) em Macaé - RJ. Foram feitos: 1) Alteração na distribuição da gordura corporal, mensurados por parâmetros antropométricos e lipodistrofia autorreferida; 2) Perfil bioquímico; 3) Associação entre tempo diagnóstico do HIV e tratamento com antirretroviral. RESULTADOS Incluíram-se 54,47% (n=67) do sexo masculino, 45,52% (n=56) do feminino, com média de idade de 37 anos. Destes, 87 eram pessoas vivendo com HIV, 29% (n=25) possuíam lipodistrofia autorreferida; tempo médio de infecção pelo vírus e tratamento antirretroviral (5,80±4,56 e 5,14±3,82 anos), respectivamente. Os pacientes com lipodistrofia autorreferida tiveram maior alteração na distribuição da gordura corporal entre 3-6 anos de diagnóstico do HIV e um perfil colesterolêmico negativo. O tempo de tratamento com antirretroviral influenciou o colesterol total e os triglicerídeos, mesmo para os pacientes sem lipodistrofia autorreferida, com mais de nove anos sob tratamento. CONCLUSÃO Neste estudo, o perfil colesterolêmico negativo se relacionou principalmente ao tempo de tratamento com antirretroviral, mesmo para os pacientes sem lipodistrofia autorreferida e as alterações na distribuição da gordura corporal, mensuradas por antropometria, se associaram especialmente ao tempo de infecção pelo HIV naqueles com lipodistrofia autorreferida.

Sarcopenia and its components in adult renal transplant recipients: prevalence and association with body adiposity.

Sarcopenia is a progressive and generalised skeletal muscle disorder associated with adverse outcomes. Ageing causes primary sarcopenia, while secondary causes include chronic kidney disease (CKD), long-term use of glucocorticoids and obesity. The aim of the present study was to evaluate the prevalence of sarcopenia using guidelines recommended by the European Working Group on Sarcopenia in Older People (EWGSOP, 2010; EWGSOP2, 2018) and the Foundation of the National Institutes of Health (FNIH) and analyse the relationship between sarcopenia and body adiposity in adult renal transplant recipients (RTR). This was a cross-sectional study of adult RTR (BMI ≥ 18·5 kg/m2). Body composition was evaluated by dual-energy X-ray absorptiometry (DXA) and anthropometry. Glomerular filtration rate was estimated (eGFR) by CKD-Epidemiology Collaboration equation. The prevalence of sarcopenia in adult RTR (n 185; 57 % men, 50 (se 0·82) years and eGFR 55·80 (se 1·52) ml/min) was 7 % (FNIH), 11 % (EWGSOP2) and 17 % (EWGSOP). Low muscle mass, muscle function and physical performance affected, respectively, up to 28, 46 and 10 % of the participants. According to EWGSOP and EWGSOP2, body adiposity evaluated by anthropometry and DXA (percentage trunk fat) was lower in participants with sarcopenia. Conversely, according to the FNIH criteria, RTR with sarcopenia presented higher waist:height ratio. The present study suggests that adult RTR sarcopenia prevalence varies according to the diagnostic criteria; low muscle mass, low muscle function and low physical performance are common conditions; the association of body adiposity and sarcopenia depends on the criteria used to define this syndrome; and the FNIH criteria detected higher adiposity in individuals with sarcopenia.

Female genital image: is there a relationship with body image?

OBJECTIVE: Dissatisfaction with body image may extend to the genital region, and the most dissatisfied with their bodies are women. To analyze the relation between body image and genital image in female, and to verify demographic and/or clinical factors related to body image and genital image. MATERIALS AND METHODS: This is a cross-sectional study in 421 women. The Body Shape Questionnaire-34 (BSQ-34) was used to evaluate body image perception; scores ≤110 indicate no dissatisfaction. Also, the female genital self-image scale-7 (FGSIS-7) was used to evaluate genital self-image; scores range between 7 and 28, with higher values considered to indicate a more positive genital self-image. The relation between body image and genital image was determined using the Pearson Correlation test, as well as the relation of these with body mass index (BMI) and age. The relation between these data and genital image was determined by using the ANOVA test or the independent t-test (statistical difference was accepted as p<0.05). In order to verify predictors of dissatisfaction with body image, variables with p<0.10 were inserted into the logistic regression model and checked if they remained significant (p<0.05). RESULTS: Three hundred eighty-nine women were analyzed. The mean age was 34.7±10.2 years. The mean BMI was 24.1±3.6 kg/m², 49% were single, and the mean BSQ-34 and FGSIS scores were 83.2±30.8 and 23.8±3.4, respectively. The correlation (r=-0.24) was found between body image and genital image (p<0.001). A total of 315 women indicated to be satisfied with their body and presented an FGSIS-7 score of 24±3.3. Participants who were dissatisfied with their body had an average FGSIS-7 score of 22.6±3.3. CONCLUSION: Genital image, age, and BMI influence body image. Change in the perception of body image seems to have low correlation with genital self-image in women.

Vitamin B12 status in kidney transplant recipients: association with dietary intake, body adiposity and immunosuppression.

The aim of the present study was to evaluate the prevalence of vitamin B12 (B12) deficiency in kidney transplant recipients (KTR) and its possible association with B12 dietary intake, body adiposity and immunosuppressive drugs. In this cross-sectional study, we included 225 KTR, aged 47·50 (sd 12·11) years, and 125 (56 %) were men. Serum levels of B12 were determined by chemiluminescent microparticle intrinsic factor assay and the cut-off of 200 pg/ml was used to stratify KTR into B12-sufficient or B12-deficient group. B12 dietary intake was evaluated by three 24 h dietary recalls and was considered adequate when ≥2·4 µg/d. Body adiposity was estimated after taking anthropometric measures and using the dual-energy X-ray absorptiometry (DXA) method. B12 deficiency was seen in 14 % of the individuals. B12-deficient group, compared with the B12-sufficient group, exhibited lower intake of B12 (median 2·42 (interquartile range (IQR) 1·41-3·23) v. 3·16 (IQR 1·94-4·55) µg/d, P = 0·04) and higher values of waist circumference (median 96·0 (IQR 88·0-102·5) v. 90·0 (IQR 82·0-100·0) cm, P = 0·04). When the analysis included only women, B12 deficiency was associated with higher total and central body adiposity measurements obtained with anthropometry (BMI, body adiposity index, waist and neck circumferences) and DXA (total and trunk body fat). Among individuals with adequate intake of B12, the deficiency of this vitamin was more frequently seen in those using mycophenolate mofetil (MMF) (17 %) v. azathioprine (2 %), P = 0·01. In conclusion, the prevalence of B12 deficiency in KTR was estimated as 14 % and was associated with reduced intake of B12 as well as higher adiposity, especially in women, and with the use of MMF.

High abdominal adiposity and low phase angle in overweight renal transplant recipients.

Obesity is associated with increased risk of cardiovascular disease (CVD). Body mass index (BMI) is the most used parameter for obesity screening. However, the evaluation of CVD risk in overweight individuals should include the assessment of body fat distribution and body composition. Renal transplant recipients (RTR) have a high CVD risk and frequently present weight gain and loss of lean mass. The aim of this study was to evaluate body fat distribution and body composition in overweight RTR. This cross-sectional study was conducted with 86 RTR and 86 hypertensive individuals (comparison group, CG) presenting BMI 25-35 Kg/m2 and 45-70 years. Anthropometric evaluation included BMI, waist circumference, waist-to-height ratio, and a body shape index. Body composition was evaluated with bioelectrical impedance analysis (BIA). Glomerular filtration rate was estimated (eGFR) by CKD-EPI equation. RTR group (RTRG) and CG presented similar age and BMI. RTRG when compared to CG presented lower percentage of women and eGFR; higher central adiposity; and lower values of reactance, intracellular water, body cell mass and phase angle, more consistently observed in women. This study suggests that overweight RTR present higher abdominal adiposity and impairment in BIA parameters that are sensitive indicators of impaired membrane integrity, water distribution, and body cell mass.

Obstructive sleep apnea in non-dialyzed chronic kidney disease patients: Association with body adiposity and sarcopenia.

OBJECTIVES: Obstructive sleep apnea (OSA) is a risk factor for cardiovascular disease (CVD), the main cause of mortality in chronic kidney disease (CKD). Although the prevalence of OSA in patients with CKD has not been established, a few studies suggest that it is higher than in the general population, potentially increasing the risk for CVD. Obesity increases the risk, whereas sarcopenia has been suggested as a consequence of OSA in the general population. To our knowledge, these associations have not been adequately evaluated in patients with CKD. The aim of this study was to evaluate OSA frequency and its association with total and upper body adiposity and sarcopenia in non-dialyzed CKD patients. METHODS: This cross-sectional study included 73 patients with stages 3b-4 CKD (42 men, 62.9 ± 1.1 y of age). Glomerular filtration rate was estimated by the CKD-Epidemiology Collaboration equation. Patients were assessed for OSA by Watch-PAT200 (apnea-hypopnea index ≥5 events hourly; Itamar Medical), total body adiposity by dual-energy x-ray absorptiometry (DXA) and body mass index (BMI), upper body adiposity by anthropometric parameters and by trunk and visceral fat by DXA, and sarcopenia. RESULTS: OSA frequency was 67% (N = 49). Both total and upper body adiposity were associated with the presence and severity of OSA. In non-obese patients (BMI <30 kg/m2), upper body obesity increased significantly the frequency of OSA. OSA association with sarcopenia was blunted when BMI was included in regression model. CONCLUSIONS: Results from the present study suggest that in non-dialyzed CKD patients OSA is very common and associated with total and upper body obesity, but not with sarcopenia.

O impacto da disfunção sexual na qualidade de vida feminina: um estudo observacional / The impact of sexual dysfunction on the quality of life of women: an observational study

INTRODUÇÃO: A saúde sexual envolve diversos componentes em relação à sexualidade, como biológico, cultural, psicológico e social. Quando alguns desses fatores são atingidos, pode-se originar um quadro de disfunção sexual. OBJETIVO: investigar a qualidade de vida em mulheres com disfunção sexual. MATERIAIS E MÉTODOS: Estudo observacional comparativo, de corte transversal, realizado em mulheres de 18 a 59 anos do CAAP da EBMSP. Excluídas: mulheres com histórico de doença psiquiátrica grave, portadoras de doenças crônico-degenerativas neurológicas, com dispareunia de causas orgânicas, em tratamento fisioterapêutico e gestantes. Foi utilizado a FSFI ≥ 26 para o grupo com disfunção e < 26 para o grupo comparação. Instrumentos de avaliação aplicados: FSFI e 36-Item Short-Form Health Survey (SF-36). A comparação das medianas dos domínios do SF-36 e FSFI entre os grupos foi realizada pelo teste Mann-Whitney (teste não paramétrico), e das variáveis categóricas com a disfunção sexual foi feita a partir do teste qui-quadrado. RESULTADOS: Amostra 36 paciente,18 em cada grupo. As variáveis sociodemográficas e clínicas que apresentaram diferença estatística foram renda (0,001) e escolaridade (0,011). No FSFI, todos os domínios apresentaram significância (0,00). No SF-36, ao comparar os dois grupos, 06 domínios apresentaram significância estatística. CONCLUSÃO: Os resultados mostram que mulheres com disfunção sexual apresentam um impacto negativo em alguns dos aspectos da qualidade de vida. Importante salientar que, a escolaridade e a renda familiar não foram homogêneas entre os grupos, sendo assim, diante da característica do estudo, não é possível aferir relação causa e consequência na disfunção sexual com a qualidade vida das participantes.

INTRODUCTION: Sexual health involves several components in relation to sexuality, such as biological, cultural, psychological and social. When some of these factors are reached, a picture of sexual dysfunction may result. OBJECTIVE: To investigate quality of life in women with sexual dysfunction. MATERIALS AND METHODS: A cross-sectional, observational, observational study of 18- to 59-year-old women from the EBMSP CAAP. Excluded: women with a history of severe psychiatric illness, carriers of neurological chronic degenerative diseases, with dyspareunia of organic causes, in physiotherapeutic treatment and pregnant women. FSFI ≥ 26 was used for the group with dysfunction and <26 for the comparison group. Assessment instruments applied: FSFI and 36-Item Short-Form Health Survey (SF-36). The comparison of the medians of the SF-36 and FSFI domains between the groups was performed by the Mann-Whitney test (non-parametric test), and the categorical variables with the sexual dysfunction were done using the chi-square test. RESULTS: Sample 36 patient, 18 in each group. The sociodemographic and clinical variables that presented statistical difference were income (0.001) and schooling (0.011). In the FSFI, all domains presented significance (0.00). In the SF-36, when comparing the two groups, 06 domains presented statistical significance. CONCLUSION: The results show that women with sexual dysfunction have a negative impact on some aspects of quality of life. It is important to emphasize that schooling and family income were not homogeneous between the groups, so, due to the characteristics of the study, it is not possible to measure cause and consequence relationship in sexual dysfunction with quality of life of the participants.

Vitamin D status in renal transplant recipients living in a low-latitude city: association with body fat, cardiovascular risk factors, estimated glomerular filtration rate and proteinuria.

Recent evidence suggests that vitamin D deficiency is associated with CVD, impaired kidney function and proteinuria. To date, no study has evaluated these associations in renal transplant recipients (RTR) adjusting for body adiposity assessed by a 'gold standard' method. This study aimed to evaluate the vitamin D status and its association with body adiposity, CVD risk factors, estimated glomerular filtration rate (eGFR) and proteinuria in RTR, living in Rio de Janeiro, Brazil (a low-latitude city (22°54'10"S)), taking into account body adiposity evaluated by dual-energy X-ray absorptiometry (DXA). This cross-sectional study included 195 RTR (114 men) aged 47·6 (sd 11·2) years. Nutritional evaluation included anthropometry and DXA. Risk factors for CVD were hypertension, diabetes mellitus, dyslipidaemia and the metabolic syndrome. eGFR was evaluated using the Chronic Kidney Disease Epidemiology Collaboration equation. Serum 25-hydroxyvitamin D (25(OH)D) concentration was used to define vitamin D status as follows: 10 % (n 19) had vitamin D deficiency (30 ng/ml). Percentage of body fat (DXA) was significantly associated with vitamin D deficiency independently of age, sex and eGFR. Lower 25(OH)D was associated with higher odds of the metabolic syndrome and dyslipidaemia after adjustment for age, sex and eGFR, but not after additional adjustment for body fat. Hypertension and diabetes were not related to 25(OH)D. Lower serum 25(OH)D was associated with increasing proteinuria and decreasing eGFR even after adjustments for age, sex and percentage of body fat. This study suggests that in RTR of a low-latitude city hypovitaminosis D is common, and is associated with excessive body fat, decreased eGFR and increased proteinuria.

Limpoma de tamanho incomum em lábio inferior / Lipoma of incomun size in inferior lip

Embora ocorra com frequência considerável em outras áreas do corpo, particularmente na região dorsal, abdômen e ombros de adultos, o lipoma é considerado uma neoplasia mesenquimal benigna pouco frequente quando presente na cavidade oral, representando cerca de 5% dos tumores bucais. O presente trabalho relata um caso de lipoma em lábio inferior, de tamanho atípico, num paciente de 40 anos de idade, em que o tratamento proposto foi a biópsia excisional sob anestesia local. Os autores realizaram revisão da literatura e discussão sobre o assunto.

Although it happens frequently considerable in other areas of the body, particularly in the backs, abdomen and adults' shoulders, the lipoma is considered a benign mesenquimal neoplasia little frequent when present in the oral cavity, acting about 5% of the buccal tumors. The present paper reports a case of lipoma in inferior lip, of atypical size, in a 40 year-old patient, where the proposed treatment was the biopsy excisional under local anesthesia, being the piece put in physiologic serum the 0,9% and observed flotation of the same. The authors done a briefly literature review and discussion about the subject.

Nutriçäo protéica: impacto da nutriçäo e outros fatores que afetam o metabolismo das proteínas, peptídeos e aminoácidos durante a infância / Protein nutrition: the impact of nutrition and other factors in the protein, peptides and amino acids metabilism during infancy

Proteínas, peptideos e aminoácidos säo substratos essenciais para a integridade e a funçäo celular. O que faz com que o metabolismo desses substratos seja täo diferente dos demais é a presença de nitrogênio em suas moléculas. Alguns dos principais componentes do nosso organismo contêm nitrogênio, como o DNA, RNA, fodfolipídeos e sais biliares, sintetizados de formas mais simples e representadas pelos aminoácidos já descritos. Na criança, aminoácidos anteriormente estudados e até já indentificados como essenciais ou "condicionalmente" essenciais passam a ter maior relevancia metabólica e nutricional. Aminoácidos neurotransmissores e seus precursores estäo intimamente ligados ao desenvolvimento cérebral, principalmente no período neonatal. Estudos que associam a investigaçäoda atividade enzimática esclarecem, em parte, as diferentes respostas bioquímicas do organismo imaturo e em desenvolvimento, o que merece especial atençäo. Entendemos que o acompanhamento do pediatra dessas novas funçöes de grande impacto nutricional "velhos substratos com novas funçöes" é fundamental.(au)

Impacto de múltiplas biópsias em dois pontos distintos da superfície pleural no diagnóstico de tuberculose / Impact of multiple biopsies in two different sites of the pleural surface for the diagnosis of tuberculosis

Com o objetivo de avaliar se a retirada de maior número de fragmentos pleurais em um único sítio (A), bem como se a biópsia em um segundo sítio (B) da sua superfície, através do mesmo orifício cutâneo, acrescenta em rendimento diagnóstico aos três fragmentos habitualmente retirados, conduzimos um estudo prospectivo no Hospital Octávio Mangabeira, envolvendo 115 pacientes com indicação de biópsia pleural. Os fragmentos pleurais foram colocados em três frascos distintos: FRA1-3 = 3 primeiros fragmentos, FRA4-8 = 5 fragmentos subseqüentes e FRB1-5 = 5 fragmentos em segundo sítio da superfície pleural. Era retirada a agulha até o subcutâneo, feitas inclinação lateral e reintrodução no espaço pleural. A análise dos fragmentos provindos do FRA1-3 evidenciou granuloma em 72/92 casos de tuberculose (78,3 por cento) e no FRA4-8 e FRB1-5, em 74/92 casos (80,5 por cento). Em 6/92 pacientes foram encontrados pleurite inespecífica no FRA1-3 e granuloma no FRA4-8, resultando em acréscimo diagnóstico de 8,3 por cento (6 aos 72 pacientes). Em 7/92 pacientes (7,6 por cento) a HP foi inespecífica no sítio A e mostrou granuloma no sítio B, resultando em acréscimo diagnóstico de 9,0 por cento (7 aos 78 pacientes). A concordância histológica intra-observador teve um índice kappa de 0,62 (0,54 a 0,70) e interobservador de 0,64 (0,56 a 0,72). Concluímos que a realização de múltiplas biópsias em dois sítios diferentes da superfície pleural diagnosticou 13 pacientes que não obteriam diagnóstico definitivo se fossem retirados apenas três fragmentos pleurais, resultando em incremento diagnóstico de 18,0 por cento (13 aos 72 diagnosticados no FRA1-3), sendo considerado significativo do ponto de vista médico e social.
