We studied avian development in 49 to 153 species of temperate and tropical New World passerine birds to determine how growth rates, and incubation and nestling periods, varied in relation to other life-history traits. We collected growth data and generated unbiased mass and tarsus growth rate estimates (mass n = 92 species, tarsus n = 49 species), and measured incubation period (n = 151) and nestling period (n = 153), which we analyzed with respect to region, egg mass, adult mass, clutch size, parental care type, nest type, daily nest predation rate (DMR), and nest height. We investigated covariation of life-history and natural-history attributes with the four development traits after controlling for phylogeny. Species in our lowland tropical sample grew 20% (incubation period), 25% (mass growth rate), and 26% (tarsus growth rate) more slowly than in our temperate sample. Nestling period did not vary with respect to latitude, which suggests that tropical songbirds fledge in a less well-developed state than tharacteristics of each region influence physiological processes of passerines, and thus, how they can shape the evolution of life histories. While development traits clearly vary with respect to latitude, trait distributions overlap broadly. Life-history and natural history associations differ for each development trait, which suggests that unique selective pressures or constraints influence the evolution of each trait.Leishmania species are responsible for a broad spectrum of diseases, denominated Leishmaniasis, affecting over 12 million people worldwide. During the last decade, there have been impressive efforts for sequencing the genome of most of the pathogenic Leishmania spp. as well as hundreds of strains, but large-scale proteomics analyses did not follow these achievements and the Leishmania proteome remained mostly uncharacterized. Here, we report a comprehensive comparative study of the proteomes of strains representing L. braziliensis, L. panamensis and L. guyanensis species. Proteins extracted by SDS-mediated lysis were processed following the multi-enzyme digestion-filter aided sample preparation (FASP) procedure and analysed by high accuracy mass spectrometry. „Total Protein Approach” and „Proteomic Ruler” were applied for absolute quantification of proteins. Principal component analysis demonstrated very high reproducibility among biological replicates and a very clear differentiation of the three species.

We further characterized the epidemiology of Shigella in the first two years of life in a multisite birth cohort. We tested 41,405 diarrheal and monthly non-diarrheal stools from 1,715 children for Shigella by quantitative PCR. To assess risk factors, clinical factors related to age and culture positivity, and associations with inflammatory biomarkers, we used log-binomial regression with generalized estimating equations. The prevalence of Shigella varied from 4.9%-17.8% in non-diarrheal stools across sites, and the incidence of Shigella-attributable diarrhea was 31.8 cases (95% CI 29.6, 34.2) per 100 child-years. The sensitivity of culture compared to qPCR was 6.6% and increased to 27.8% in Shigella-attributable dysentery. Shigella diarrhea episodes were more likely to be severe and less likely to be culture positive in younger children. Older age (RR 1.75, 95% CI 1.70, 1.81 per 6-month increase in age), unimproved sanitation (RR 1.15, 95% CI 1.03, 1.29), low maternal education ( less then 10 years, RR 1.14, 95% CI 1.03, 1.26), initiating complementary foods before 3 months (RR 1.10, 95% CI 1.01, 1.20), and malnutrition (RR 0.91, 95% CI 0.88, 0.95 per unit increase in weight-for-age z-score) were risk factors for Shigella. There was a linear dose-response between Shigella quantity and myeloperoxidase concentrations. The burden of Shigella varied widely across sites, but uniformly increased through the second year of life and was associated with intestinal inflammation. Culture missed most clinically relevant cases of severe diarrhea and dysentery.

The key metric for monitoring the progress of deworming programs in controlling soil-transmitted helminthiasis (STH) is national drug coverage reported to the World Health Organization (WHO). There is increased interest in utilizing geographically-disaggregated data to estimate sub-national deworming coverage and equity, as well as gender parity. The Demographic and Health Surveys (DHS) offer a potential source of sub-national data. This study aimed to compare deworming coverage routinely reported to WHO and estimated by DHS in pre-school aged children to inform global STH measurement and evaluation.

We compared sub-national deworming coverage in pre-school aged children reported to WHO and estimated by DHS aligned geospatially and temporally. We included data from Burundi (2016-2017), Myanmar (2015-2016), and the Philippines (2017) based on data availability. WHO provided data on the date and sub-national coverage per mass drug administration reported by Ministries of Health. DHS included maternally-repo32 of 40 districts). National deworming coverage from DHS estimates were similar by gender within countries.

Agreement of deworming coverage reported to WHO and estimated by DHS data was heterogeneous across countries, varying from broadly compatible in Burundi to largely discrepant in Myanmar. DHS data could complement deworming data reported to WHO to improve data monitoring practices and serve as an independent sub-national source of coverage data.

The natural development of BCRs must be understood in order to design vaccines for highly mutable pathogens such as influenza and HIV. BCR diversity is induced by naturally occurring combinatorial „V(D)J” rearrangement, mutation, and selection processes. Most current methods for BCR sequence analysis focus on separately modeling the above processes. Statistical phylogenetic methods are often used to model the mutational dynamics of BCR sequence data, but these techniques do not consider all the complexities associated with B cell diversification such as the V(D)J rearrangement process. In particular, standard phylogenetic approaches assume the DNA bases of the progenitor (or „naive”) sequence arise independently and according to the same distribution, ignoring the complexities of V(D)J rearrangement. In this paper, we introduce a novel approach to Bayesian phylogenetic inference for BCR sequences that is based on a phylogenetic hidden Markov model (phylo-HMM). This technique not only integrates a naive rearrangement model with a phylogenetic model for BCR sequence evolution but also naturally accounts for uncertainty in all unobserved variables, including the phylogenetic tree, via posterior distribution sampling.

Rehabilitation and physical therapy have been adapting to the telehealth era, increasing accessibility and improving the continuity of attention in geographically remote populations with disabilities. Due to the spread of infection by SARS-CoV-2, many professionals have had to adapt their work to telerehabilitation practices, which require the best evidence at short notice and in summarized form. In this context, this protocol has been developed to evaluate the effectiveness of telerehabilitation as a care strategy in physical therapy for different conditions, populations, and contexts.

An overview will be carried out in the format of a rapid review. It will include systematic reviews of different conditions, populations, and contexts, where the intervention to be evaluated is telerehabilitation by physical therapy. The outcomes considered will be clinical effectiveness depending on the specific condition, functionality, quality of life, satisfaction, adherence, and safety. A search will be carried out of the MEDLINE/PubMed, EMBASE, and Cochrane Library databases. Studies will be selected in duplicate with any discrepancies resolved by a third reviewer. Data extraction and risk of bias assessment will be carried out by a reviewer with non-independent verification by a second reviewer. The findings will be reported qualitatively by tables and figures.

The principles of the value of the research question, the methodological rigor, scientifically qualified investigators, an independent evaluation of the protocol, and timely and accurate publication of the results will be complied with. The complete review will lead to the publication of at least one article, and the results will be widely disseminated at various levels of decision-making.

This protocol has been registered in PROSPERO with the number CRD42020185640.

Health personnel, including physicians, are a fundamental part of the first line of defense against the SARS-CoV-2 pandemic.

To characterize the clinical manifestations and course of the first cases of contagion by SARS-CoV-2 in doctors of Peru.

We present a series of six cases of doctors infected by SARS-CoV-2, with confirmed positivity for COVID-19, showing the daily evolution from the diagnosis of the disease, its main signs and symptoms, evolution, and until the outcome in each case.

Five were men. The median age was 28 years (interquartile range 27 to 33). In three cases the physician worked more than 12 hours a day in emergency and hospitalization services and not wear a mask at all times. The most frequent symptoms were axillary temperature above 38°C, malaise, dry cough, and odynophagia (the latter in three of the cases). The diagnosis was made at a median of 3 days (interquartile range 3 to 4 days). The symptoms that persisted the most were dry cough (present during ten days in four doctors). Dysgeusia was the only symptom with the most extended duration (15 days in only one doctor). In the six cases, the course was favorable. However, these doctors found it difficult to return to functions in their hospital centers adequately.

Despite a small number of cases, it is the first report detailing the evolution of symptoms day by day, which can help for occupational health and even for case surveillance and monitoring.

Chronic interstitial pneumonitis is the most common presentation. However, acute pulmonary toxicity is rare and has a higher case fatality rate. We present a 61-year-old patient with persistent atrial fibrillation who, after a one-month treatment with oral amiodarone at a low dose impregnation of 400 mg/day, develops acute pulmonary toxicity, with radiographic and tomographic resolution after antiarrhythmic suspension and steroid treatment.
