Thus, it is extremely necessary that the analysis of the affliction affects these women in a biopsychosocial context, in order to discuss and comprehend in a more reliable manner the affection from the perception of the disease, origin, and psychic pain mechanisms. Methods: Systematic review with meta-analysis, using the PRISMA protocol. The study period was 2016 and the keywords included “microcephaly” and “abortion”, one at a time and then combined with the Boolean operator “AND.” The statistical analysis was done using the BioEstat 5.0 program. Calculation was based on an adjustment of Mantel-Haenszel random effect. Results: 41,046 registrations were found. Of this total, 40,992 articles were excluded because they only mentioned the fact or referred to spontaneous abortion, did not analyze abortion on the eyes of microcephaly, only treated with Zika virus, or were repeated. Limitations: Psychic pain and suffering need studies in the mother/son/disease relation, which were not found in the databases. The article was based on other sources. Conclusions: The pains vary in different areas of the female life, since internal conflicts, gender violence, stress, fear, insecurity, psychologic torture, grieve, loneliness, among other kinds of psychic suffering. More studies on psycho-emotional themes need to be promoted to discuss the female suffering on a wider vision, closer to the reality faced by these women.展开更多

In addition, using the hippocampus and standards of these three compounds we validated an isocratic fluorescence HPLC procedure for a simultaneous detection of them in a single chromatogram within a total run time of about 12 min. Reproducibility for TDP, TMP and B1 was 2.66%, 4.50% and 7.43% (intraday) and 37.54%, 25.39% and 25.87% (interday), respectively. Recovery assays were between 96.0% and 101.7%. The calibration curves were linear and the concentrations of the three compounds, all in nanomolar range, were determined in the brain areas and in the blood samples. When compared to the current methods in the literature, this new method provides information on essential variables, such as linearity range and limit of detection, reproducibility and stability of thiamine, TMP and TDP in rat brain samples. The present data on sample processing and B1 and its phosphate ester level determinations are the first to be validated using hippocampus samples of rats.展开更多

This work has the objective of investigating the relationships between variabilities of the El Ni?o-South Oscillation (ENSO) and greater epidemics of dengue in Rio de Janeiro city. To accomplish this goal, the analysis and signal decomposition by cross-wavelet transform (WT) was applied to obtain the cross variability associated with variations of power and phase of both signals by characteristic periods and along with the time series. Data considered in the analysis are (the decimal logarithm of normalized value) of the monthly available notifications of dengue worsening, provided by the public health system of Brazil, and the Southern Oscillation Index (SOI) Ni?o 3.4 data, provided by the National Oceanic and Atmospheric Administration (NOAA), in the period 2000-2017. A maximum cross-wavelet power close to 0.45 was obtained for the representative period of 1 year and also to periods between 3 and 4 years, associated with the positive phase of the SOI index (i.e. , La Ni?a) or with a transition to the positive phase. The evolution of the combined variability of SOI and dengue can be expressed by progressive differences in phase along the time, eventually resulting in yielding phases (i.e., La Niña-Dengue epidemic).展开更多
