ABSTRACT
BACKGROUND: Maintaining autonomy is one of the principal objectives for seniors and people with psychiatric disorders. Podiatric medical care can help them maintain autonomy. This work aimed to characterize and quantify the support of the toes in a psychiatric population by analyzing the influence of psychotropic medications and toe and foot support parameters on the prevalence of falls. METHODS: We conducted a cross-sectional descriptive study in 67 participants (31 people with psychiatric disorders and 36 without diagnosed disorders [control population]). Toe support pattern was analyzed with a pressure platform. Variables were measured in static and dynamic loading and related to falls and psychotropic medication use. RESULTS: The psychiatric population fell more than the control population and presented less toe-ground contact in static measurements, although it has more foot-ground contact time. Maximum toe pressure during toe-off is also less intensive in the psychiatric population and is related to people who take psychotropic medications. CONCLUSIONS: Toe support pattern could be used as a predictive factor for falls and to improve stability in these populations.

BACKGROUNDThe spread of COVID-19 from Wuhan China, has been alarmingly rapid. Epidemiologic techniques succeeded in containing the disease in China, but efforts have not been as successful in the rest of the World, with a total of 29,155,581 confirmed cases of COVID-19, including 926,544 deaths worldwide as of September 15, 2020. Projections are for continued new infections and deaths if no effective therapeutic interventions can be initiated over the next several months. We performed a systematic review to determine the potential time course for development of treatments and vaccines, focusing on availability now and continuing in the last half of 2020. METHODS Clinical TrialsWe reviewed up-to-date information from several sources to identify potential treatments for COVID-19: The Reagan-Udall Expanded Access Navigator COVID-19 Treatment Hub was used to track the efforts of companies to develop agents. We focused on trials completed as of September 1, 2020 on identified agents We used several different sources: (A) covid-trials.org, then validated results on (B) clinicaltrials.gov and the (C) World Health Organizations International Clinical Trials Registry Platform (WHO ICTRP). We excluded studies which were clearly observational, with no randomization, control, or comparison group. We further set a cutoff of 100 for numbers of subjects, since smaller trial size could lack statistical power to establish superiority of the intervention over the control. PublicationsWe searched for published trial results on pubmed.gov and on medRxiv, the preprint server, and used a targeted Google search to find announcements of unpublished trial results RESULTS Clinical Trials in RecruitmentAs of our cutoff date of April 1, 2020, we found 409 trials meeting our minimum requirement of 100 subjects. The WHO Solidarity megatrial for hospitalized patients was launched in over 100 countries, actively comparing hydroxychloroquine (HCQ), lopanovir/ritonavir (LPV/r) alone and in combination with interferon beta-1, and remdesivir. The LPV/r alone and HCQ arms have already been discontinued. Of these, only 9 were conducted on outpatients. A few vaccine trials are hoping to complete Phase 3 enrollment by the end of the third quarter 2020, but a prolonged follow-up of patients will likely be required. Clinical trials CompletedAs of September 1, 2020, there were 231 trials reporting completion, Of these, only 59 studies enrolled 100 or more subjects. There were 34 trials in hospitalized patients, 9 directed at outpatients, and 8 prevention studies, Published DataAs of September 1, 2020 we found 70 publications reporting findings in human studies on 13 classes of drugs and on 6 vaccines. There were 33 randomized placebo or active control studies; the rest were retrospective observational. Only seven publications dealt with outpatient care, the rest all in hospitalized patients. Available TreatmentsAt this time, remdesivir and convalescent plasma have been granted emergency use authorization in the U.S.A., solely for hospitalized patients. There is also support for glucocorticoid treatment of the COVID-19 respiratory distress syndrome. No treatments or prophylaxis are offered for outpatients. CONCLUSIONCOVID-19 is propagated primarily by infected ambulatory individuals. There have been no options brought forward for prevention and non-hospital treatment with only a few randomized, controlled outpatient studies expected to yield results in time to impact on the continuing pandemic by the end of 2020. It will be necessary for public health authorities to make hard decisions, with limited data, to prevent the continued spread of the disease. The choices will be hardest when dealing with possible early release of safe and effective vaccines which would, of course, be of greatest benefit to the Worlds population.
ABSTRACT
BACKGROUND: Dermatomycoses are a group of pathologic abnormalities frequently seen in clinical practice, and their prevalence has increased in recent decades. Diagnostic confirmation of mycotic infection in nails is essential because there are several pathologic conditions with similar clinical manifestations. The classical method for confirming the presence of fungus in nail is microbiological culture and the identification of morphological structures by microscopy. METHODS: We devised a nested polymerase chain reaction (PCR) that amplifies specific DNA sequences of dermatophyte fungus that is notably faster than the 3 to 4 weeks that the traditional procedure takes. We compared this new technique and the conventional plate culture method in 225 nail samples. The results were subjected to statistical analysis. RESULTS: We found concordance in 78.2% of the samples analyzed by the two methods and increased sensitivity when simultaneously using the two methods to analyze clinical samples. Now we can confirm the presence of dermatophyte fungus in most of the positive samples in just 24 hours, and we have to wait for the result of culture only in negative PCR cases. CONCLUSIONS: Although this PCR cannot, at present, substitute for the traditional culture method in the detection of dermatophyte infection of the nails, it can be used as a complementary technique because its main advantage lies in the significant reduction of time used for diagnosis, in addition to higher sensitivity.

Etiolated Arabidopsis thaliana seedlings germinated in the presence of reducing buffers such as reduced gluthathione (GSH) and dithiothreitol (DTT) have altered morphology. GSH and DTT inhibited hypocotyl elongation in a dose-dependent manner. The GSH-mediated effect was prevented by the simultaneous addition of extracellular ATP (eATP). NADPH oxidase (NOX) activity and endogenous nitric oxide (NO) generation were required to mediate eATP action on the hypocotyl elongation. A correlation was observed between hypocotyl length, eATP concentration and NO production. The action of eATP and NO on superoxide (O(2)(-)) accumulation and peroxidase activity was investigated. The O(2)(-) distribution was regulated by eATP and NO during hypocotyl elongation. Our data suggest that a finely tuned balance of redox status and optimal levels of ATP and NO are essential to regulate the hypocotyl elongation in the dark.

O presente projeto de intervenção tem como objetivo diminuir a incidência de gravidez na adolescência no âmbito da UBS Santa Teresinha, município Assunção do Piauí, PI. A proposta de intervenção aponta as repercussões sociais da maternidade na adolescência tais como: evasão escolar, trabalho precoce e desestruturação familiar. Diante desta realidade, do arcabouço teórico e da vontade de se intensificar ações em saúde voltadas para os jovens e adolescentes em situação de vulnerabilidade social, propõe-se o delineamento de estratégias para o enfrentamento do problema. Através da realização de palestras, vídeos educativos e fornecimento de orientações, que serão mais tarde estendidas para pais e família. Em geral, não apenas adolescentes se sentirão satisfeitos, mas não tenderão a ter novas expectativas para avaliar a importância de uma saúde reprodutiva planejada e desejada, sem consequências fatais.
