Rheumatic heart disease (RHD) remains endemic in less-resourced regions and countries and results in high medical and non-medical costs to households, health systems, and society. This scoping review maps out the available evidence on the economic impact of RHD and its antecedents and suggests future research priorities.

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. We identified articles through systematic electronic database search supplemented by expert knowledge of unpublished literature. Studies were included if they collected empirical RHD-related costing data as a primary or secondary objective and if the data were collected from 2000 onward. Main quantitative findings by intervention, costing perspective, and location were charted, and a standardized quality assessment tool was used to appraise included studies.

The index search identified 2519 electronic records and two grey-literature graduate theses. Six full texts were inclu Assembly resolution on RHD, high-quality, local cost estimates will be needed from a range of representative, RHD-endemic countries.

In patients with severe mitral regurgitation (MR), additional echocardiographic indices could be helpful to optimize surgical timing before irreversible left heart myocardial dysfunction has occurred. We investigated the correlation of left atrial (LA) strain by speckle tracking echocardiography with prognosis after mitral surgery for severe MR, and its association with LA fibrosis.

71 patients with primary severe MR undergoing pre-operative echocardiographic assessment were initially enrolled. Exclusion criteria were other valvular disease>moderate, history of coronary artery disease, heart failure (HF), hypertrophic cardiomyopathy, left bundle branch block, previous pacemaker implantation, heart transplantation, poor acoustic window. The primary endpoint was the occurrence of composite events (HF and mortality); the secondary endpoint was post-operative functional capacity (NYHA and Borg CR10 class). LA fibrosis was assessed by atrial biopsy specimens in a subset of patients.

Of 65 eligible patients, the primary endpoint occurred in 30 patients (medium follow-up 3.7±1years for event-group, 6.8±1years for non-event group). After Kaplan-Meier analysis, peak atrial longitudinal strain (PALS) provided good risk stratification (5-year event-free survival90±5% for PALS≥21% vs 30±9% for PALS<21%, p<0.0001); it was an independent and incremental predictor of outcome in four multivariate Cox adjusted models. There was also an association between PALS and the secondary endpoint (NYHA r

=0.11, p=0.04; Borg CR10 r

=0.10, p=0.02) and an inverse correlation between PALS<21% and LA fibrosis (r

0.80, fibrosis 76.6±20.7% vs 31.9±20.8%;p<0.0001).

Global PALS emerged as a reliable predictor of outcome and functional capacity for severe primary MR, and as a marker of LA fibrosis.

The recovery of atrial contractile (AC) after maze has been concerned and even questioned. Now, studied the AC recovery degree and its influencing factors.

237 patients with valvular long-standing persistent atrial fibrillation (AF) were retrospectively grouped according to whether sinus rhythm(SR) maintained and AC restored SR-AC (163 cases), SR-no-AC (41 cases) and AF-no-AC (33 cases). SR-AC were grouped according to Em/Am ratio. Em/Am≤2 showed that the AC recovered well.

The SR maintained rate (161/177, 90.96%) in patients underwent the cut-and-sew maze III (CSM) was significantly higher than that in cryoablation (43/60, 71.7%). Preoperative AF duration had no significant difference among three groups (P=0.679). Maze methods had significant relationship with whether SR recovered, P<0.05, but no significant relationship with whether AC recovered in SR maintained patients (P=0.280). Nearly 80% (163/204) patients can recover AC, among 156 patients (156/204, 76.5%) recovered contractile of left and ri, no matter what maze method is used. MVP patients should be treated with maze more actively than RHD patients.

The interaction between genetic, epigenetic and environmental factors plays an important role in the aetiology of hypertension. GWAS and observational studies link the C677T polymorphism in methylenetetrahydrofolate reductase (MTHFR) with hypertension, while riboflavin, the MTHFR cofactor, has been shown to reduce blood pressure and global DNA methylation in homozygous (TT genotype) individuals. It is currently unclear whether riboflavin modulates DNA methylation of other hypertension-related genes.

To compare DNA methylation of hypertension-related genes in adults stratified by MTHFR genotype and effect of riboflavin intervention in adults with the variant MTHFR 677TT genotype.

Pyrosequencing was carried out for hypertension-related genes (ACE, AGTR1, GCK, GNA12, IGF2, MMP9 and NOS3) in blood samples from participants in previous trials (CC, n=40; TT, n=40). The effect of intervention with riboflavin (1.6mg/d for16 weeks) or placebo on DNA methylation was investigated in adults with the variant MTHFR 677TT genotype (n=80).

Individuals with the MTHFR 677TT v CC genotype had significantly higher average DNA methylation at NOS3 (+1.66%, P=0.044). In response to riboflavin supplementation in TT individuals, there was an increase in average DNA methylation at IGF2 (+1.09%, P=0.019) and a decrease at ACE (-0.44%, P=0.021) in females only. Specific CpG sites were hypomethylated in GNA12 and hypermethylated in AGTR1.

This study provides the first RCT evidence that riboflavin alters DNA methylation of hypertension-related genes in adults with the MTHFR 677TT genotype, providing some insight into mechanisms linking hypertension with the genotype-specific response of BP to riboflavin.

Occupational eosinophilic bronchitis (OEB) has been described only as anecdotal case reports.

We investigated the clinical and inflammatory characteristics of subjects with OEB identified in a cohort of subjects who completed a specific inhalation challenge (SIC) with occupational agents.

In this retrospective multicenter study, OEB was defined by (1) a fall in FEV

less than 15% during the SIC and the absence of nonspecific bronchial hyperresponsiveness both before and after the SIC and (2) a postchallenge increase of 3% or more in sputum eosinophils. The subjects who fulfilled these criteria were compared with 226 subjects with a negative SIC and 30 subjects with a positive SIC who failed to show baseline nonspecific bronchial hyperresponsiveness.

An isolated increase in postchallenge sputum eosinophils was documented in 33 of 259 subjects (13%) with a negative SIC. These subjects reported significantly more often an isolated cough at work compared with the negative and positive SIC controls. When compared with positive SIC controls, the subjects with OEB experienced less frequently work-related wheezing and reported a shorter duration of symptoms at work. The sensitivity of the post-SIC increase in fractional exhaled nitric oxide in identifying OEB among subjects with a negativeSIC was low, ranging from 43% to 24% using cutoff values of 8 ppb to 17.5 ppb, whereas the specificity was high (90%-97%).

This study highlights the relevance of induced sputum analysis in the investigation of work-related asthma symptoms to identify isolated increases in sputum eosinophils that are consistent with a diagnosis of OEB.

The increasing prevalence of multidrug-resistant microorganisms (MDRO) is increasing the frequency of poor clinical outcomes, prolonging hospitalizations, and raising healthcare costs. This study evaluated the eradication efficacy of fecal microbiota transplantation (FMT) and identified microbial and functional biomarkers of MDRO decolonization.

Fecal solution obtained from healthy unrelated donors was infused in the participants' guts which had been colonized with carbapenemase-producing enterobacteriacea (CPE), vancomycin-resistant enterococci (VRE), or both CPE and VRE. Fecal samples from recipients were collected and microbiome changes before and after FMT were assessed.

Twenty-four (68.6%) out of 35 patients were decolonized within one year of receiving FMT. Multivariate analysis showed that FMT (FMT hazard ratio (HR) = 5.343, 95% confidence interval (CI) = 1.877-15.212, p = 0.002) and MDRO types (CPE HR = 11.146, 95% CI = 2.420-51.340, p = 0.002; CPE/VRE HR = 2.948, 95% CI = 1.200-7.246, p = 0.018; VRE served as the reference) were significant independent factors associated with time to decolonization. check details Microbiota analysis showed higher richness and biodiversity before FMT resulted in VRE decolonization. The species Clostridium ramosum and the genuses Anaerostipes and Eisenbergiella could serve as taxonomic biomarkers and K02017 could serve as a functional biomarker for VRE clearance.

FMT is an effective way to decolonize MDRO and its effectiveness may be predicted by microbiome analysis.

FMT is an effective way to decolonize MDRO and its effectiveness may be predicted by microbiome analysis.Here, we describe a novel workflow combining informatic and experimental approaches to enable evidence-based prioritising of targets from large sets in parallel. High-throughput protein production and biophysical fragment screening is used to identify those targets that are tractable and ligandable. As proof of concept we have applied this to a set of antibacterial targets comprising 146 essential genes. Of these targets, 51 were selected and 38 delivered results that allowed us to rank them by ligandability. The data obtained against these derisked targets have enabled rapid progression into structurally enabled drug discovery projects, demonstrating the practical value of the fragment-based target screening workflow.Drug discoveries can, when used appropriately, save lives. Since 1970, cancer death rates among people aged under 65 have halved in countries such as the USA and the UK. Despite pharmaceutical market imperfections and fears about the prices of new treatments, further progress should be possible during the 2020s. Anticancer medicine outlays account for 0.1-0.2% of the gross domestic product (GDP) of developed countries. Total cancer service spending typically stands at ∼0.8% of GDP. The affordability of these sums is a political calculation. Improvements in the efficiency of drug development and global access to effective therapies are desirable. However, from a public interest perspective, these goals should not be pursued in ways that understate the value of better treatment outcomes and threaten the funding available for ongoing innovation.
