This article describes and analyses the characteristics of the expansion of private dental education in Brazil from 1996 to December 2018 and its relationships with public policies and the country's labour and education market in dentistry.
The study used an exploratory and descriptive quantitative approach involving standardised data-collection techniques from open-access secondary databases.
From 1996 to 2018 there was an overall increase of 315% in dental schools (582% in the private sector and 49% in the public sector). Brazil had 374 dental schools in December 2018, 307 of which were private and 67 of which were public. The 374 schools offered 47,192 admission places, 89% of which were private. In five states, dental education is 100% private, while in another 19 states the private supply exceeds 70% of the total. In the other three states this offer is between 40% and 67%. From 1996 to 2016, the private sector's share of dental school graduates was 66%. Women represented 73% of Brazilian dental-school graduates in 2016.
Privatisation of dental education in Brazil raises challenges for the development of policies, planning, organisation of care, and structuring of the training process for dentists, as well as the dynamics of the labour market in the health system.

In dendritic cells (DCs), RA drives the expression of CD103 (integrin αE ), a functionally relevant DC subset marker. In this study, we analyzed the cell type specificity and the molecular mechanisms involved in RA-induced CD103 expression. We show that RA treatment caused a significant up-regulation of CD103 in differentiated monocyte-derived DCs and blood DCs, but not in differentiated monocyte-derived macrophages or T cells. DC treatment with an RA receptor α (RARα) agonist led to an increase in CD103 expression similar to that in RA treatment, whereas RARA gene silencing with small interfering RNA blocked RA-induced up-regulation of CD103, pointing to a major role of RARα in the regulation of CD103 expression. To elucidate RA-induced signaling downstream of RARα, we used Western blot analysis of RA-treated DCs and showed a significant increase of p38 mitogen-activated protein kinase (MAPK) phosphorylation. In addition, DCs cultured with RA and a p38 MAPK inhibitor had a significantly reduced expression of CD103 compared with DCs cultured with RA only, indicating that p38 MAPK is involved in CD103 regulation. In summary, these findings suggest that the RA-induced expression of CD103 is specific to DCs, is mediated primarily through RARα and involves p38 MAPK signaling.Under the concept of "united airway diseases," the airway is a single organ wherein upper and lower airway diseases are commonly comorbid. The upper and lower airways are lined with respiratory epithelium that plays a vital role in immune surveillance and modulation as the first line of defense to various infective pathogens, allergens, and physical insults. Recently, there is a common hypothesis emphasizing epithelium-derived cytokines, namely IL-25, IL-33, and TSLP, as key regulatory factors that link in immune-pathogenic mechanisms of allergic rhinitis (AR), chronic rhinosinusitis (CRS), and asthma, mainly involving in type 2 inflammatory responses and linking innate and adaptive immunities. Herein, we review studies that elucidated the role of epithelium-derived triple cytokines in both upper and lower airways with the purpose of expediting better clinical treatments and managements of AR, CRS, asthma, and other associated allergic diseases via applications of the modulators of these cytokines.
Given the global shortage of the health workforce and the nature of diseases, strengthening and improving health care systems become a necessity. One of the solutions that is recommended by the literature is to utilize advanced practice nurses (APNs) to accelerate the progress toward the Sustainable Development Goals and universal health coverage (UHC).
To delineate APN practice and competencies in relation to UHC and primary care in Jordan from the perspective of nurse administrators, clinical nurse specialist, academics, and policymakers.
A descriptive exploratory survey design was utilized to identify APN competencies that are important in achieving UHC. The survey developed by one of the authors (JH) at a PAHO Collaborating Center to delineate APN practice and APN competencies was adapted and utilized. A convenience sample of 94 nurse leaders was recruited from the education sector, nursing associations, councils, and hospitals.
The results showed that all four competencies (clinical care; interdisciplinary and patient-centered communication; systems of care; and using evidence for best practice) were rated as agree/strongly agree across all four domains. There was a consensus of participates on dimensions of all competency domains.
The current study confirms that the role of APNs is still in its infancy in Jordan. The current study provides nurse educators with baseline information that can be utilized as a framework for APN education programs. The faculty readiness to start new competency-based APN programs or revise the current graduate programs needs to be assessed.

Heterogeneity in solar UVR exposure may explain the diversity in skin cancer incidence between men and women. This, however, has not previously been investigated in Danish outdoor workers using UVR dosimetry. The aim of this study was to evaluate sex differences in solar UVR dosimetry in Danish outdoor workers on working and leisure days. A cross-sectional design was used to collect dosimetry data during the Danish summer season (May to September). Analysis was based on an electronic questionnaire and dosimetry data from 450 outdoor workers (88 women, 362 men). Dosimetry data were reported as standard erythema dose (SED). The daily median SED (Interquartile range) on working days was 1.6 (2.5) in men and 1.5 (2.1) in women while on leisure days it was 0.5 (1.4) in men and 0.6 (1.3) in women. Analysis by multiple linear regression did not show any association between daily median SED and sex on either working or leisure days. In conclusion, solar UVR exposure in Danish outdoor workers did not vary according to sex.In rice, the florigens Heading Date 3a (Hd3a) and Rice Flowering Locus T 1 (RFT1), OsFD-like basic leucine zipper (bZIP) transcription factors, and Gf14 proteins assemble into florigen activation/repressor complexes (FACs/FRCs), which regulate transition to flowering in leaves and apical meristem. Only OsFD1 has been described as part of complexes promoting flowering at the meristem, and little is known about the role of other bZIP transcription factors, the combinatorial complexity of FAC formation, and their DNA-binding properties. Here, we used mutant analysis, protein-protein interaction assays and DNA affinity purification (DAP) sequencing coupled to in silico prediction of binding syntaxes to study several bZIP proteins that assemble into FACs or FRCs. We identified OsFD4 as a component of a FAC promoting flowering at the shoot apical meristem, downstream of OsFD1. The osfd4 mutants are late flowering and delay expression of genes promoting inflorescence development. Protein-protein interactions indicate an extensive network of contacts between several bZIPs and Gf14 proteins. selleck compound Finally, we identified genomic regions bound by bZIPs with promotive and repressive effects on flowering. We conclude that distinct bZIPs orchestrate floral induction at the meristem and that FAC formation is largely combinatorial. While binding to the same consensus motif, their DNA-binding syntax is different, suggesting discriminatory functions.
To evaluate the effects of UGT1A1*6 and UGT1A1*28 polymorphisms on the safety and efficacy of metronomic irinotecan-based chemotherapy (IBC) in Chinese patients with pulmonary neuroendocrine tumours (PNTs).
Sixty-eight PNT patients who received metronomic IBC were observed. The quantitative fluorescent polymerase chain reaction was used to detect UGT1A1*6 and UGT1A1*28 polymorphisms. The follow-up data were collected to investigate the relationship between different genotypes and adverse drug reactions. The clinical outcomes of metronomic IBC were also evaluated.
In the genotype-toxicity association analysis, patients with homozygous UGT1A1*6 had the highest incidence of grade 3-4 diarrhoea (P=0.010). Compared to other groups, patients with the haplotype of UGT1A1*28 showed a trend towards an increased incidence of grade 4 neutropaenia (P=0.047). A higher incidence of grade 3-4 leucopaenia was found in groups with UGT1A1*1/*28 (P=0.023) and UGT1A1*28/*28 (P=0.022). Grade 1 total bilirubin elevation was associated with the homozygous UGT1A1*6 mutation (P=0.027) or any UGT1A1*6 variants (P=0.047). However, neither UGTA1A*28 nor UGT1A1*6 showed any significant association with tumour response or clinical outcomes.
The impact of UGT1A1 polymorphisms varies in different irinotecan-based chemotherapies. UGT1A1*6 and UGTA1A*28 were useful for the prediction of irinotecan-related severe toxicity in Chinese PNT patients treated with metronomic IBC.

The oral rehydration solution is the most efficient method to treat cholera; however, it does not interfere in the action mechanism of the main virulence factor produced by Vibrio cholerae, the cholera toxin (CT), and this disease still stands out as a problem for human health worldwide. This review aimed to describe therapeutic alternatives available in the literature, especially those related to the search for molecules acting upon the physiopathology of cholera.
New molecules have offered a protection effect against diarrhoea induced by CT or even by infection from V.cholerae. The receptor regulator cystic fibrosis channel transmembrane (CFTR), monosialoganglioside (GM1), enkephalinase, AMP-activated protein kinase (AMPK), inhibitors of expression of virulence factors and activators of ADP-ribosylarginine hydrolase are the main therapeutic targets studied. Many of these molecules or extracts still present unclear action mechanisms.
Knowing therapeutic alternatives and their molecular mechanisms for the treatment of cholera could guide us to develop a new drug that could be used in combination with the rehydration solution.
