Diagnostic yield of capillary compared to venous glucose in the diagnosis of hypoglycorrhachia in children: A prospective,observational study

IntroductionThe ratio of cerebrospinal fluid (CSF) glucose and blood glucose is of major relevance, conducting to the diagnosis of hypoglycorrhachia, which is a sign of neuroinfection, as well as a number of neurological diseases of genetic or neoplastic etiology. Glucose in capillary sample (glucometry) is a low cost, readily available technique, as compared to venous glucose. This study aims to compare glucometry to venous glucose in the diagnosis of hypoglycorrhachia in pediatric population.MethodsProspective cross-sectional study based on data obtained from lumbar punctures in the period from February 2017 to January 2019 in a specialized pediatric institution in Colombia.Results97 patients were analyzed, aged 1 month to 17 years old, mean 7.67 years, 52 (53.61%) were female. 26 (26.8%) were diagnosed with hypoglycorrhachia. Pearson correlation coefficient for absolute venous and capillary glucose was 0.54, and 0.55 for the ratios of CSF glucose/venous glucose and CSF glucose/glucometry, which support a linear correlation between the variables in both, absolute values and ratios. Intraclass correlation coefficient was calculated for both, the venous glucose and glucometry ratios, which was 0.52, revealing a moderate agreement among the tests. Sensitivity and specificity of CSF glucose/glucometry, as compared to gold standard are 73.1% and 60.6% respectively; whereas predictive positive value (PPV) and negative predictive value (NPV), were 40.4% and 86.0%.ConclusionGlucometry cannot replace the glucose in venous sample in the diagnosis of hypoglycorrhachia in children.     

Sexual function,satisfaction with life and menopausal symptoms in middle-aged women

Purpose

To assess sexual function, satisfaction with life (SWL), and menopause-related symptoms among mid-aged Spanish women.

Materials and methods

Cross-sectional study of 260 women, aged 40–59, attending the public gynecology consultations completed the 14-item Changes in Sexual Functioning Questionnaire (CSFQ-14), the SWL Scale (SWLS), the Menopause Rating Scale (MRS), and a socio-demographic questionnaire.

Results

Median [inter quartile range] age was 47 [8.0] years, 87.7% had a stable partner, 27.0% were postmenopausal, and 53.9% had increased body mass index (BMI). The prevalence of sexual dysfunction was 46.5% (CSFQ-14 score ≤ 41). Postmenopausal status was associated with lower CSFQ-14 scores (worse sexual function) and severe menopausal symptoms whereas there were not significant differences in SWLS scores. CSFQ-14 scores correlated with SWLS (p < 0.04), and inversely correlated with menopausal symptoms (p < 0.02). Multiple linear regression analysis model predicted 26.6% of the total CSFQ-14 score variance, and higher scores (better sexual function) were correlated with better SWL, and inversely correlated to female age and worse menopausal symptoms. A second model predicted 38.4% of the SWLS score variance. The SWLS score correlated with the total CSFQ-14 score and BMI, and inversely correlated with economical problems, female tobacco use, lack of healthiness, menopausal symptoms, not having a partner, and partner's lack of healthiness.

Conclusions

Lower sexual function was related to low SWL, age and menopausal symptoms while low SWLS score was related with economical problems, smoking, menopausal symptoms, and partner factors.     

Sex-specific environmental influences affecting MS development

Vitamin D status, smoking, and Epstein–Barr virus infection (EBV) may all contribute to explain differences in disease prevalence and incidence of Multiple Sclerosis (MS). MS affects women more often than men, and recent cross-sectional study assessments provide evidence of increased female to male prevalence in relapsing remitting MS patients, suggesting that sex hormones may exert an active role in disease pathogenesis. Studies in both humans and animal disease models demonstrate a functional synergy for the immunomodulatory effects of Vitamin D3 and 17-β estradiol. Both smoking and EBV infection clearly increase MS risk, and smoking history has also been associated with poorer disease prognosis. However, neither factor can explain the recent trend indicating greater female prevalence. Therefore, large population-based case–control studies from well defined geographic areas with homogeneous populations should be performed, in order to define environmental factor effects, and sex hormone influences, to better understand prevalence and incidence gender differences observed.     

Categorias de Aptidão Física Baseadas no VO2max em População Brasileira com Suposto Alto Nível Socioeconômico e sem Cardiopatia Estrutural

Background The most widely used data for cardiorespiratory fitness (CRF) referrals are from the Cooper Clinic, which uses calculated maximal oxygen uptake (VO₂max) values.Objective To develop CRF values from cardiopulmonary exercise testing (CPX) in a Brazilian population with high socioeconomic level and free of structural heart disease. VO₂max testing results were compared with the Cooper Clinic and FRIEND Registry data.Methods CPX data from consecutive individuals between January 1,2000, and May 31,2016 were used in this study. Inclusion criteria were: VO₂max by a pre-specified definition. We built a CRF chart according to VO₂max percentiles: very poor (≤20%), poor (20-40%), fair (40-60%), good (60-80%), excellent (80-90%), and superior (≥90%). Kappa correlation was used to analyze our data in comparison with that of the other two databases. Statistical tests with p<0.005 were considered significant.Results Final cohort included 18,186 tests: 12,552 men, 5,634 women (7–84 years). The most recurrent response was “good” (20.2%). There was a mean difference in weight, height, body mass index (BMI), and age in the CRF chart. An inverse correlation existed between VO₂max and age, weight, and BMI. Using a linear regression and these variables, a predictive equation was developed for VO₂max. Our findings differed from that of the other databases.Conclusion We developed a classification for CRF and found higher values in all classification ranges of functional capacity in contrast to the Cooper Clinic and FRIEND Registry. Our findings offer a more accurate interpretation of ACR in this large Brazilian population sample when compared to previous standards based on the estimated VO2max.
