The use of self-collected cervical sample could be a simple and inexpensive approach in cervical cancer screening programs due to their high pre-analytical stability.The distinction between chronic HBeAg-negative hepatitis (CHB) and chronic HBeAg-negative infection (CIB) can be challenging and important for providing advice on prognosis, as well as determining need for treatment. The aim of the present study was to evaluate pgRNA levels in treatment-naïve HBeAg-negative chronic HBV-infected patients. In addition, pgRNA levels were compared to traditional markers in order to assess their clinical utility. A retrospective study was carried out, including 85 cases of CHBs and 74 CIBs. Globally, when the virological markers (pgRNA, qHBsAg, and HBV DNA) were analyzed, significant differences were found between the CHB and CIB groups (P less then 0.001). Overall, positive correlations were demonstrated, as follows between pgRNA levels and qHBsAg (Spearman r=0.30, P less then 0.001), between pgRNA and HBV DNA (Spearman r=0.73, P less then 0.001), and between pgRNA and ALT (Spearman r=0.67, P less then 0.001). Out of the 85 CHB patients, 82 (96.5%) agreed to start treatment. At baseline, 38/82 patients, as well as the 3 untreated CHB patients, had undetectable pgRNA levels. The 74 CIB carriers also had undetectable pgRNA levels. During the follow-up period, no patients experienced viral reactivation or progression of liver disease. These results suggest that the addition of plasmatic HBV-pgRNA levels to the traditional diagnostic flowchart of HBeAg-negative patients may improve the correct identification of cases at risk, especially patients with occasional increases in HBV viremia.Since the beginning of the HIV/AIDS epidemy in the eighties, hundreds of phase I human immunization studies were performed, however, only nine tested efficacy in phase IIb/III clinical trials. While immunogens for SARS-CoV-2 did move along the development and clinical trial pipeline at unprecedent speed, two HIV immunization vaccine trials, started in 2016 and 2017, did meet non-efficacy criteria at the interim analysis and were thus, halted by the Data and Safety Monitoring Boards. The challenges in the quest to develop a safe, effective and durable HIV vaccine are unchanged. However, as research on HIV vaccine discovery moves forward there are many new tools and platform technologies to iterate vaccine strategies faster. Among these, there is a growing interest to conduct experimental medicine approaches where product development is directly informed by human data at an early stage of product development.Malaria is long known as a deadly vector borne infection, caused by five parasite species of the coccidian genus Plasmodia that are present in as many as 85 countries. Despite significant progresses have been achieved to control the infection by early diagnosis and artemisinin combination treatment, insecticide-treated nets and indoor residual spraying, malaria still represents a major public health issue in many endemic low-income countries. New diagnostic tools of higher sensitivity and specificity are now available for use in endemic countries to better guide diagnosis and treatment. In particular, highly sensitive rapid antigenic tests are now available and the loop-mediated isothermal amplification is a very promising and highly sensitive diagnostic tool. After 2015, decreasing morbidity and mortality trends have been stagnating because of limited funding, emergence of parasite and vector resistance to drugs and insecticides respectively and, recently, by the disrupting effect of COVID-19 pandemic. The incomplete knowledge of the complex immunity of malaria infection has slowed the development of an effective vaccine. However, in 2021, the RTS-S vaccine, however of suboptimal protective efficacy, has been made available for routine use in children above 5 months of age. Population movements has increased the chance of observing imported malaria in non-endemic areas, where malaria competent vectors may still exist.Here, we report novel empirical results from a psychophysical experiment in which we tested the echolocation abilities of nine blind adult human experts in click-based echolocation. We found that they had better acuity in localizing a target and used lower intensity emissions (i.e., mouth clicks) when a target was placed 45° off to the side compared with when it was placed at 0° (straight ahead). We provide a possible explanation of the behavioral result in terms of binaural-intensity signals, which appear to change more rapidly around 45°. The finding that echolocators have better echo-localization off axis is surprising, because for human source localization (i.e., regular spatial hearing), it is well known that performance is best when targets are straight ahead (0°) and decreases as targets move farther to the side. This may suggest that human echolocation and source hearing rely on different acoustic cues and that human spatial hearing has more facets than previously thought.

The role of doctors is changing, and mental health care is increasingly dominated by professional groups other than doctors. In this qualitative study, we investigated how psychiatrists perceive their role and position in mental health care.

Seven psychiatrists were given in-depth interviews based on an interview guide. The transcribed material was analysed using systematic text condensation.

The interview material was grouped into four cross-cutting topic categories Several informants perceived themselves as professional guarantors who step in when other interventions have failed. find more Many felt like guest workers in the therapeutic pathways of other professional groups, without an adequate framework for following up the patients properly. Some described the health authorities' prioritisation of mental health as a patient pathway bureaucracy, where more stringent demands for control and documentation of treatment and decisions to use coercive measures divert time and resources away from patient treatment. Several psychiatrists felt that unified management led to diffusion of responsibility, with an unclear distribution of professional responsibility between the interdisciplinary head of unit and the specialist.

The psychiatrists in the study appeared to have clear professional authority in the clinic, but their role seems to be under pressure. Interdisciplinary, unified line management, equal responsibility for treatment accorded to specialists in psychology, and the absence of psychiatrists in the management appear to have undermined the psychiatric perspective in mental health care.

Here we describe a patient with a distinctive but relatively rare disease.Acute exacerbation of rash is common in patients with atopic dermatitis and has diverse aetiology. We describe a patient with atopic dermatitis who developed a pruritic, burning and weeping rash. The rash quickly worsened and developed into a serious condition for which early diagnosis and treatment are crucial.Merkel cell carcinoma is an uncommon but aggressive tumour with a high metastatic potential. A rapidly growing, non-tender cutaneous tumour on sun-exposed areas of the body in older patients should raise suspicion of the condition. It may be necessary to combine the patient history with clinical, radiological and pathological findings in order to make the correct diagnosis. Excision with a 1-2 cm margin, direct closure and simultaneous sentinel-node biopsy should be performed without delay. Adjuvant radiation therapy of the tumour site may be relevant. After the diagnosis is made, assessment and treatment should take place in hospitals with special experience of the condition.How long does speciation take? The answer to this important question in evolutionary biology lies in the genetic difference not only among species, but also among lineages within each species. With the advance of genome sequencing in non-model organisms and the statistical tools to improve accuracy in inferring evolutionary histories among recently diverged lineages, we now have the lineage-level trees to answer these questions. However, we do not yet have an analytical tool for inferring speciation processes from these trees. What is needed is a model of speciation processes that generates both the trees and species identities of extant lineages. The model should allow calculation of the probability that certain lineages belong to certain species and have an evolutionary history consistent with the tree. Here, we propose such a model and test the model performance on both simulated data and real data. We show that maximum-likelihood estimates of the model are highly accurate and give estimates from real data that generate patterns consistent with observations. We discuss how to extend the model to account for different rates and types of speciation processes across lineages in a species group. By linking evolutionary processes on lineage level to species level, the model provides a new phylogenetic approach to study not just when speciation happened, but how speciation happened.

The coronavirus disease 2019 (COVID-19) pandemic has brought additional burden to patients living with immune-mediated rheumatic diseases (IMRDs), especially at the beginning of 2020, for which information for this population is lacking.

COnVIDa is a cross-sectional study on patients with IMRD from all regions of Brazil who were invited to answer a specific and customized Web questionnaire about how they were facing the COVID-19 pandemic, especially focusing on health care access, use of medications, and patient-reported outcomes related to IMRD activity. The questionnaire was applied from June 1 to 30, 2020.

In total, 1722 of 2576 patients who answered the Web questionnaire were included in the final analysis. Participants were most frequently women, 56% were between 31 and 50 years old, and most (55%) has private health insurance. The most commonly reported IMRD was rheumatoid arthritis (39%), followed by systemic lupus erythematosus (28%). During the study period, 30.7% did not have access to rheumatology consultations, and 17.6% stopped chronic medications. Telemedicine was reported in 44.8% of patients.

COnVIDa demonstrated a negative impact on health care access and treatment maintenance of patients living with IMRD during the COVID-19 pandemic. However, it also presented an uptake of telemedicine strategies. Data presented in this study may assist future coping policies.
