4% (61.8 to 89.1%) with CaOH/Iodof paste. Consequently, a non-inferiority of GP paste was observed when compared to CaOH/Iodof paste (p < 0.001).

GP paste has a non-inferior success rate against CaOH/Iodof paste used as filling material for pulpectomy in primary teeth.

We described the presence of Helicobacter pylori (HP) and estimated the prevalence of primary and secondary resistance using molecular detection in gastric biopsies of Ecuadorian patients.

66.7% (238/357) of the patients demonstrated the presence of HP using CerTest qPCR. Of these, 69.79% (104/149) were without previous HP eradication treatment and 64.42% (134/208) with prior HP eradication treatment. The mutation-associated resistance rate for clarithromycin was 33.64% (primary resistance) and 32.82% (secondary resistance), whereas that in levofloxacin the primary and secondary resistance was 37.38% and 42%, respectively. For tetracycline and rifabutin, primary and secondary resistance was 0%. Primary and secondary resistance for metronidazole and amoxicillin could not be evaluated by genotypic methods (PCR and sequencing).

The analysis of mutations in gyrA, 23S rRNA and 16S rRNA is useful to detect bacterial resistance as a guide for eradication therapy following failure of the first-line regimen.

This study carried out in an Ecuadorian population indicates that the resistance of HP to first-line antibiotics is high, which may contribute to the high rates of treatment failure, and other treatment alternatives should be considered.

Clinical presentations of coronavirus disease 2019 (COVID-19) among children with asthma have rarely been investigated. This study aimed to assess clinical manifestations and outcome of COVID-19 among children with asthma, and whether the use of asthma medications was associated with outcomes of interest.

The Global Asthma Network (GAN) conducted a global survey among GAN centers. Data collection was between November 2020 and April 2021.

Fourteen GAN centers from 10 countries provided data on 169 children with asthma infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 was asymptomatic in 58 (34.3%), mild in 93 (55.0%), moderate in 14 (8.3%), and severe/critical in 4 (2.4%). Thirty-eight (22.5%) patients had exacerbation of asthma and 21 (12.4%) were hospitalized for a median of 7days (interquartile range 3-16). https://www.selleckchem.com/products/abt-199.html Those who had moderate or more severe COVID-19 were significantly more likely to have exacerbation of asthma as compared to those who were asymptomatic or had mild COVID-19 (adjusted odds ratio (adjOR) 3.97, 95% CI 1.23-12.84). Those who used inhaled bronchodilators were significantly more likely to have a change of asthma medications (adjOR 2.39, 95% CI 1.02-5.63) compared to those who did not. Children who used inhaled corticosteroids (ICS) did not differ from those who did not use ICS with regard to being symptomatic, severity of COVID-19, asthma exacerbation, and hospitalization.

Over dependence on inhaled bronchodilator may be inappropriate. Use of ICS may be safe and should be continued in children with asthma during the pandemic of COVID-19.

These mixed perovskite crystals show suppression of the orthorhombic phase and a lower tetragonal-to-cubic phase-transition temperature compared to MAPbBr3 . A distinct behavior is observed in the temperature-dependent photoluminescence properties of MAPbBr3 and mixed DMA/MAPbBr3 crystals due to the different organic cation dynamics governing the phase transition(s). Furthermore, lateral photodetectors based on these crystals show that, at room temperature, the mixed crystals possess higher detectivity compared to MAPbBr3 crystals caused by structural compression and reduced surface trap density. Remarkably, the mixed-crystal devices exhibit large enhancement in their detectivity below the phase-transition temperature (at 200 K), while for the MAPbBr3 devices only insignificant changes are observed. The high detectivity of the mixed crystals makes them attractive for visible-light communication and for space applications. The results highlight the importance of the synthetic technique for compositional engineering of halide perovskites that governs their structural and optoelectronic properties.
Geotrichum spp can be responsible for severe infections in immunocompromised patients. We aim to describe Geotrichum-related infections in the ICU and to assess risk factors of mortality.

Retrospective multicentre study, conducted in 14 French ICUs between 2002 and 2018, including critically ill adult patients with proven or probable infection related to Geotrichum species. Data were obtained from the medical charts.

Thirty-six patients, median age 60years IQR [53; 66] were included. Most of the patients had haematological malignancies (78%). The reason for ICU admission was shock in half of the patients (n=19, 53%) and respiratory failure in thirteen patients (36%). Median SOFA score was 8.5 IQR [7; 15]. Time between ICU admission and fungal diagnosis was 2.5days [-1; 4]. Infection was disseminated in 27 (75%) patients with positive blood cultures in 25 patients (69%). Thirty patients (83%) received curative antifungal treatment in the ICU, in a median time of 1day [0;1] after ICU admission. Twenty-four patients (67%) died in the ICU and hospital mortality rate was 69%. The number and extent of organ failures, as represented by SOFA score, were associated with mortality.

This study demonstrates poor outcome in critically ill patients with Geotrichum-related infections, which encourages a high level of suspicion.

We tested the hypothesis that multiple obesity-related risk factors (obesity, physical activity, cardiopulmonary physical fitness, sleep-disorder breathing (SDB), and sleep quality) are associated with childhood asthma using a Mendelian randomization (MR) design. Furthermore, we aim to investigate whether these risk factors were associated with incident asthma prospectively.

In total, 7069 children aged 12 from the Taiwan Children Health Study were enrolled in the current study. Cross-sectional logistic regression, one-sample MR, summary-level MR sensitivity analyses, and prospective survival analyses were used to investigate each causal pathway.

In MR analysis, three of the five risk factors (obesity, SDB, and sleep quality) were associated with asthma, with the highest effect sizes per inter-quartile range (IQR) increase observed for sleep quality (odds ratio [OR]=1.42; 95% confidence interval [CI] 1.06 to 1.92) and the lowest for obesity (OR=1.08; 95% CI 1.00-1.16). In the prospective survival analysis, obesity showed the highest risk of incident asthma per IQR increase (hazard ratio [HR]=1.28; 95% CI 1.05 to 1.56), followed by SDB (HR=1.18; 95% CI 1.08 to 1.29) and sleep quality (HR=1.10; 95% CI 1.03 to 1.17).

Among the examined factors, the most plausible risk factors for asthma were obesity, SDB, and poor sleep quality. For the prevention of childhood asthma, relevant stakeholders should prioritize improving children's sleep quality and preventing obesity comorbidities such as SDB.

Endocrine therapy is highly effective at reducing tumor burden and preventing recurrence in most estrogen receptor alpha (ER) positive breast cancers. Existing drugs work either directly by targeting tumor-cell ER or indirectly by inhibiting estrogen production in stromal cells with aromatase inhibitors (AI). However, many stromal cells also express ER and the direct impact of endocrine therapies on ER + stromal cells remain unclear. In this study, we investigated how neoadjuvant endocrine therapy (NET) directly effects stromal cells by measuring changes in stomal components of the TME that favor tumor progression. We previously defined two major subsets of tumor-associated stromal cells (TASCs) CD146 positive/CDCP1 negative (TASCCD146 ), CD146 negative/CDCP1 positive (TASCCDCP1 ), and generated a differentially expressed genes list associated with further understand the role of endocrine therapy on TME remodeling, tumor progression, and patient outcomes.Noncoding RNAs (ncRNAs) such as microRNAs (miRNAs), long noncoding RNAs (lncRNA), and circular RNAs are closely related to the biological processes related to obesity. As a miRNA that widely present in different cell types, miR497 is proved to be involved in cell development. However, research on the role of miR-497 as a key factor in regulating the development of adipocytes is still in gap. The role of miR-497 in the apoptosis and proliferation of mouse-derived adipocytes was detected by RNA-seq analysis, RT-qPCR, Western blot, immunofluorescence, and dual-luciferase reporter assay. Using miR-497 mimics to treat 3T3-L1 cells, we found that miR-497 targeted Bcl-2 to promote adipocyte apoptosis through the mitochondrial pathway, and this effect was consistent in the apoptosis model composed of palmitic acid (PA) and hydrogen peroxide (H2 O2 ). LncRNA homeodomain-interacting protein kinase 1 (lnc-hipk1) sponged miR-148b to weaken its silencing of Bcl-2, forming the competitive endogenous RNAs (CeRNAs) regulatory network. Furthermore, overexpression of lnc-hipk1 inhibited the apoptosis of adipocytes by targeting miR-497/Bcl-2. Co-treatment of miR-497 and lnc-hipk1 showed that lnc-hipk1 reversed the apoptosis of adipocytes caused by miR-497 overexpression. And in vivo experiments further confirmed that this effect was also achieved by the CeRNA system of lnc-hipk1/miR-497/Bcl-2. In summary, lnc-hipk1 targets miR-497/Bcl-2 to regulate adipocyte apoptosis through the mitochondrial pathway. This research enriches the research content of ncRNAs and CeRNA in adipocyte development, and provides new targets for the treatment of obesity and other metabolic syndromes.Youth drinking has declined in many high-income countries for two decades. This development is still largely unexplained. Developing evidence and extending our understanding as to the mechanisms behind these changes is imperative for advising governments and policy makers on how to support and maintain the trends. Given the international scope of the trends, comparative studies have been suggested for improving our understanding of the development. In this commentary, we explore the patterns observed across several waves of the European School Survey Project on Alcohol and Other Drugs between 1999 and 2019, and how these match-up with the World Values Survey. We found that the declines in youth drinking are limited to a smaller number of countries and that in Europe these are all found in two groups from the World Values Survey, protestant Europe and English-speaking countries. If the declines in youth drinking are systematic and limited to a smaller number of countries, this challenges some of the hypothesised drivers of this development, but can also help guide future research.
