on HIV transmission and control among MSM in China.
The overall impact of COVID-19 on new HIV infections and HIV-related deaths is dependent on the nature, scale and length of the various disruptions. Resources should be directed to ensuring levels of viral suppression and condom use are maintained to mitigate any adverse effects of COVID-19-related disruption on HIV transmission and control among MSM in China.
The optimal treatment strategy of combining systemic chemotherapy and radiotherapy for nasopharyngeal carcinoma (NPC) is controversial. This study aimed to compare the efficacy and toxicities of induction chemotherapy followed by intensity-modulated radiotherapy (IC-RT) versus concurrent chemoradiotherapy (CCRT) in NPC.
Of 448 stage II-IVb NPC patients treated with IC-RT or CCRT were retrospectively analysed. The primary outcome was overall survival, which was analysed by using Kaplan-Meier curves and log-rank (Mantel-Cox) test.
The median follow-up was 66months (interquartile range, 46-84months). There was no statistically significant difference in the estimated 5-year overall survival (OS), progression-free survival (PFS), distance metastasis-free survival (DMFS) and locoregional relapse-free survival (LRFS) between IC-RT group and CCRT group (OS 89.5% vs 91.7%, P=.568; PFS 85.2% vs 87.5%, P=.615; DMFS 90.9% vs 91.7%, P=.847; LRFS 92.0% vs 96.9%, P=.104). In the multivariate analysis, the treatment group (IC-RT vs CCRT) was not an independent prognostic factor for OS, PFS, DMFS and LRFS. Less advanced tumour stage and lymph node stage were predictive of higher OS. EBV-DNA level was an independent prognostic factor that was only significantly associated with LRFS.
IC-RT achieves similar survival outcomes and treatment-related toxicities as CCRT in OS, PFS, DMFS and LRFS for patients with NPC. We need multicentre randomised controlled trials to reconfirm our data.

To analyze the clinical characteristics and controllable risk factors of osteoporosis in elderly men with type-2 diabetes mellitus (T2DM).
A total of 250 elderly OP patients with T2DM were included in the present study. Patients with one or more common chronic diseases (including hypertension, coronary heart disease, heart failure, chronic bronchitis, chronic nephrosis, and cirrhosis), and a course of more than 3 years were defined as complicated with chronic diseases. Blood glucose, cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, calcium, phosphorus, glycosylated hemoglobin, urea nitrogen, creatinine, fasting insulin, liver function, and 25-hydroxy vitamin D3 levels were measured. Bone mineral density was also measured.
A total of 16 patients (6.4%) had severe osteoporosis. Furthermore, 66 patients (26.4%) had blood glucose control that reached the standard, while 176 patients (70.4%) used more than two anti-diabetic drugs. The serum testosterone level was lower than the me prevention and treatment of complications, and appropriate testosterone supplementation are necessary for preventing and curing osteoporosis.
Understanding the impact different journal articles have in any academic field is important - particularly in emerging professions. A bibliometric analysis like this does not yet exist for paramedicine, despite the rapid increase in its primary literature. The objective of the present study was to identify and analyse the 100 top-cited articles about paramedicine.
We searched the Scopus database in August 2020 for studies relating to paramedicine. After screening titles and abstracts, we extracted the citation count, journal name, publication year, and country of origin. We manually assessed whether the study was clinical or not, noted the sex of the authors, the profession of first and last authors and the study design used.
The median citation count for the top 100 papers in paramedicine was 58 (interquartile range 46-84 citations). The articles were published across 48 different journals, with Resuscitation and Prehospital Emergency Care being the two most frequent. The top-cited paramedic papers originated from 16 different countries and were written predominantly by medical doctors. Three quarters (73%) of the studies had a clinical focus, and a quarter (26%) were randomised controlled trials.
The evolution of paramedicine towards professionalism is backed up by the growth of its own body of knowledge. This analysis of the 100 most cited studies in paramedicine is the first of its kind and highlights that paramedicine articles have a high citation count and are published across numerous journals, but with a relative lack of contribution from paramedic practitioners and female researchers.

Constraints on cellular proteome may limit such expression strategies and introduce trade-offs. Resource allocation under proteome constraints has explained regulatory strategies in bacteria. It is unclear, however, to what extent these constraints can predict evolutionary changes, especially for microorganisms that evolved under nutrient-rich conditions, i.e., multiple available nitrogen sources, such as Lactococcus lactis. Here, we present a proteome-constrained genome-scale metabolic model of L. lactis (pcLactis) to interpret growth on multiple nutrients. Selleckchem Pilaralisib Through integration of proteomics and flux data, in glucose-limited chemostats, the model predicted glucose and arginine uptake as dominant constraints at low growth rates. Indeed, glucose and arginine catabolism were found upregulated in evolved mutants. At high growth rates, pcLactis correctly predicted the observed shutdown of arginine catabolism because limited proteome availability favored lactate for ATP production. Thus, our model-based analysis is able to identify and explain the proteome constraints that limit growth rate in nutrient-rich environments and thus form targets of fitness improvement.
Near-infrared fluorescence cholangiography during a laparoscopic cholecystectomy has become widely accepted as a useful auxiliary tool to visualize the extrahepatic biliary structures. We investigated the feasibility and educational value of a method with longer interval between the administration of indocyanine green and the imaging of these structures.
Approximately 18 hours before their surgery, patients (n = 51) were intravenously administered 0.25 mg/kg of indocyanine green. Each laparoscopic cholecystectomy was performed under fluorescence imaging in combination with white-light imaging. Operative outcomes including visualization of the extrahepatic biliary structures and operative time were compared between the patients on whom board-certified surgeons operated (feasibility phase; n = 18) and the patients on whom a surgery resident operated (educational phase; n = 33).
There were no adverse events related to the longer interval method. The visualization rates of extrahepatic biliary structures were comparable between the two phases. Both the mean time to divide the cystic duct and the mean time to remove the gallbladder in the educational phase were significantly longer than those in the feasibility phase (68.2 vs 24.4 minutes and 30.2 vs 15.8 minutes, P < .001 each). There was no significant difference in other operative outcomes. The operative time learning curve did not decrease with a resident's experience.
Fluorescence cholangiography with the longer interval method was feasible and could identify the extrahepatic biliary structures irrespective of the surgeon's experience; however, it did not decrease the operative time with experience.

As a new approach to DNA adductomics, we directly reacted intact, double-stranded (ds)-DNA under warm conditions with an alkylating mass tag followed by analysis by liquid chromatography/mass spectrometry. This method is based on the tendency of adducted nucleobases to locally disrupt the DNA structure (forming a "DNA bubble") potentially increasing exposure of their nucleophilic (including active hydrogen) sites for preferential alkylation. Also encouraging this strategy is that the scope of nucleotide excision repair is very broad, and this system primarily recognizes DNA bubbles.
A cationic xylyl (CAX) mass tag with limited nonpolarity was selected to increase the retention of polar adducts in reversed-phase high-performance liquid chromatography (HPLC) for more detectability while maintaining resolution. We thereby detected a diversity of DNA adducts (mostly polar) by the following sequence of steps (1) react DNA at 45°C for 2 h under aqueous conditions with CAX-B (has a benzyl bromide functional grouAX-Prelabeling is an emerging new technique for DNA adductomics, providing polar DNA adductomics in a practical way for the first time. Further study of the method is encouraged to better characterize and extend its performance, especially in scope and sensitivity.

Optimal treatment strategies for ACHD with AF are unknown. This study sought to assess outcomes of pulmonary vein isolation (PVI) ± left atrial (LA), posterior wall isolation (PWI) for adults with congenital heart disease (ACHD), and atrial fibrillation (AF).
A retrospective review of all cryoballoon (CB) PVI ± PWI procedures at a single center over a 3-year period were performed. Clinical characteristics and outcomes for patients with and without ACHD were compared. The primary outcome was the occurrence of atrial tachyarrhythmia at 12-months postablation after a 90-day blanking period.
Three-hundred and sixteen patients (mean 63 ± 12 years, [63% male]) underwent CB PVI ± PWI during the study, including 31 (10%) ACHD (simple 35%, moderate 39%complex 26%; nonparoxysmal AF in 52%). ACHD was younger (51 vs. 64 years;p < .001) with a lower CHADS

-VASc score (1.2 vs. 2.1;p = .001) but had a greater LA diameter (4.9 vs. 4.0 cm;p < .001) and a number of prior cardioversions (0.9 vs. 0.4;p < .001) versuscontrols. 12-month freedom from recurrent AF was similar for ACHD and controls (76% vs. 80%;p = .6) and remained nonsignificant in multivariate analysis (hazard ratio1.8, 95% confidence interval0.7-5.1; p = .22). At 12-months postablation, 75% of ACHD versus93% of control patients were off antiarrhythmic drug therapy (p = .07).
This study demonstrates younger age and lower conventional stroke risk, yet clinically advanced AF for ACHD relative to controls. CB PVI ± PWI was an effective strategy for the treatment of AF among all forms of ACHD with similar 12-month outcomes as compared to controls.
