Abstract
OBJECTIVES To perform a systematic review and meta-analysis and quantify the associations of total mortality with calf circumference (CC) in adults 18 years and older via combining various analyses based on empirical dichotomic CC, continuous CC, and dose-response CC. METHODS We conducted a systematic search of relevant studies in PubMed, EMBASE, Cochrane Library, and Web of Science published through April 12, 2022. This systematic review includes longitudinal observational studies reporting the relationships of total mortality with CC. We calculated the pooled relative risk (RR) and 95% confidence interval (CI) of total mortality with CC per 1 cm for each study and combined the values using standard meta-analysis approaches. Newcastle-Ottawa scale (NOS), Grading of Recommendations, Assessment, Development and Evaluations approach (GRADE), and the Instrument for assessing the Credibility of Effect Modification Analyses (ICEMAN) were assessed for meta-analyses. RESULTS Our analysis included a total of 37 cohort studies involving 62,736 participants, across which moderate heterogeneity was observed (I2=75.7%, P<0.001), but no publication bias was found. Study quality scores ranged from 6 to 9 (mean 7.7), with only three studies awarded a score of 6 (fair quality). We observed an inverse trend between total death risk and CC per 1 cm increase (RR, 0.95, 95% CI, 0.94-0.96; P<0.001; GRADE quality=high). Only a very slight difference was found among residents of nursing homes (6.9% mortality risk reduction per one cm CC increase), community-dwellers (5.4%), and those living in hospitals (4.8%), respectively (P for meta-regression=0.617). Low credible subgroup difference was found based on the ICEMAN tool. CONCLUSIONS Calf circumference is a valid anthropometric measure for mortality risk prediction in a community, nursing home, or hospital.

Abstract
UNLABELLED In this study, we integrated large-scale GWAS summary data and used the predicted transcriptome-wide association study method to discover novel genes associated with osteoporosis. We identified 204 candidate genes, which provide novel clues for understanding the genetic mechanism of osteoporosis and indicate potential therapeutic targets. INTRODUCTION Osteoporosis is a highly polygenetic disease characterized by low bone mass and deterioration of the bone microarchitecture. Our objective was to discover novel candidate genes associated with osteoporosis. METHODS To identify potential causal genes of the associated loci, we investigated trait-gene expression associations using the transcriptome-wide association study (TWAS) method. This method directly imputes gene expression effects from genome-wide association study (GWAS) data using a statistical prediction model trained on GTEx reference transcriptome data. We then performed a colocalization analysis to evaluate the posterior probability of biological patterns: associations characterized by a single causal variant or multiple distinct causal variants. Finally, a functional enrichment analysis of gene sets was performed using the VarElect and CluePedia tools, which assess the causal relationships between genes and a disease and search for potential gene's functional pathways. The osteoporosis-associated genes were further confirmed based on the differentially expressed genes profiled from mRNA expression data of bone tissue. RESULTS Our analysis identified 204 candidate genes, including 154 genes that have been previously associated with osteoporosis, 50 genes that have not been previously discovered. A biological function analysis found that 20 of the candidate genes were directly associated with osteoporosis. Further analysis of multiple gene expression profiles showed that 15 genes were differentially expressed in patients with osteoporosis. Among these, SLC11A2, MAP2K5, NFATC4, and HSP90B1 were enriched in four pathways, namely, mineral absorption pathway, MAPK signaling pathway, Wnt signaling pathway, and PI3K-Akt signaling pathway, which indicates a causal relationship with the occurrence of osteoporosis. CONCLUSIONS We demonstrated that transcriptome fine-mapping identifies more osteoporosis-related genes and provides key insight into the development of novel targeted therapeutics for the treatment of osteoporosis.

Abstract
Background Colonization has been reported to play an important role in carbapenem-resistant Enterobacterales (CRE) infection; however, the extent to which carriers develop clinical CRE infection and related risk factors in neonatal intensive care unit (NICU) patients is unclear. Aim To investigate the frequency of CRE colonization and its contribution to infections in NICU patients. Methods CRE colonization screening and CRE infection surveillance were performed in the NICU in 2017 and 2018. Findings Among 1230 unique NICU patients who were screened for CRE colonization, 144 patients tested positive (11.7%, 144/1230), with 9.2% (110/1197) in the intestinal tract, which was higher than that in the upper respiratory tract (6.6%, 62/945) (P=0.026). Gestational age, low birth weight and prolonged hospitalization were risk factors for CRE colonization (all P<0.001). Diversilab homology monitoring found an overall 17.4% (25/144) risk of infection among patients colonized with CRE. For carbapenem-resistant Klebsiella pneumoniae (CR-KP) and carbapenem-resistant Escherichia coli (CR-ECO), the risks were 19.1% (21/110) and 13.8% (4/29), respectively. The independent risk factors for CR-KP clinical infection among CR-KP carriers were receiving mechanical ventilation (odds ratio (OR), 10.177; 95% confidence interval (CI), 2.667–38.830; P=0.013), a high level of neonatal nutritional risk assessment (OR, 0.251; 95% CI, 0.072–0.881; P=0.031) and a high neonatal acute physiology II (SNAP-II) score (OR, 0.256; 95% CI, 0.882–1.034; P=0.025). Conclusions The colonization of CRE may increase the incidence of corresponding CRE infection in NICU patients. Receiving mechanical ventilation, malnutrition and critical conditions with high SNAP-II scores were independent risk factors for subsequent CR-KP clinical infection.

Abstract
BACKGROUND This study evaluated the survival benefit of asparaginase (ASP)-based versus non-ASP-based chemotherapy combined with radiotherapy in a real-world cohort of patients with early-stage extranodal nasal-type natural killer/T-cell lymphoma (ENKTCL). PATIENTS AND METHODS We identified 376 patients who received combined radiotherapy with either ASP-based (ASP, platinum, and gemcitabine; n = 286) or non-ASP-based (platinum and gemcitabine; n = 90) regimens. The patients were stratified into low-, intermediate-, and high-risk groups using the early stage-adjusted nomogram-revised risk index. Overall survival (OS) and distant metastasis (DM)-free survival (DMFS) between the chemotherapy regimens were compared using inverse probability of treatment weighting (IPTW) and multivariable analyses. RESULTS ASP-based (versus non-ASP-based) regimens significantly improved 5-year OS (84.5% versus 73.2%, P = 0.021) and DMFS (84.4% versus 74.5%, P = 0.014) for intermediate- and high-risk patients, but not for low-risk patients in the setting of radiotherapy. Moreover, ASP-based regimens decreased DM, with a 5-year cumulative DM rate of 14.9% for ASP-based regimens compared with 25.1% (P = 0.014) for non-ASP-based regimens. The survival benefit of ASP-based chemotherapy and radiotherapy remained consistent after adjusting the confounding variables using IPTW and multivariate analyses; additional sensitivity analyses confirmed these results. CONCLUSIONS The findings provided support for ASP-based chemotherapy and radiotherapy as a first-line treatment strategy for intermediate- and high-risk early-stage ENKTCL.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a lethal genetic arrhythmia that manifests by syncope or sudden death in children and young adults under stress conditions without obvious cardiac structural abnormality. A novel CPVT mutation located in the RyR2 N terminal portion has been identified in a Spanish family (RyR2R420Q). According to the studies of RyR2 function in HEK293 cell line, this mutation presented gain of function at low cytosolic intracellular Ca2+ concentration ([Ca2+]i) and loss of function at high [Ca2+]i. Moreover, KI mice heterozygous for this mutation presented bradycardia and sino-atrial node (SAN) dysfunction. Here we generated induced pluripotent stem cell (hiPSC) from two brothers (one with mutation, the other without mutation as control) of this family and differentiated them into cardiomyocytes (hiPSC-CM). In order to verify that the differentiated cells were well cardiomyocytes, we did immunofluorescence labelling to detect the α-actinin expression and found that around 90% cells were α-actinin positive in both groups of hiPS-CMs. Then the calcium transient was studied by confocal microscopy and the action potential (AP) by micro-electrode technique. The characteristics of spontaneous AP of mutated cells were mostly similar to that of control cells, but more mutated cells presented proarrhythmic behaviors under adrenergic stimulation. hiPSC-CM are immature cardiomyocytes and contract spontaneously. In order to be able to analyze [Ca2+]i transient characteristics, we paced the cells at a constant rate of 1 Hz by field stimulation through two Pt electrodes. Sarcoplasmic reticulum (SR) Ca2+ load was estimated by rapid caffeine (10 mM) application. hiPSC-CMs from the RyR2R420Q carrier presented smaller SR Ca2+ load than those from the control person, whereas their fractional release (the [Ca2+]i transient normalized by the amount of Ca2+ stored in the SR) was higher than that in control group, indicating a gain-of-function mutation. Even if SR Ca2+ load was smaller in RyR2R420Q cells, they often presented proarrhythmogenic behavior such as Ca2+ waves. The fact was further enhanced during β-adrenergic stimulation, pointing to this model as a valuable tool to study the CPVT disease in human cells.

Abstract
We measure cross-beam energy transfer (CBET) saturation by ion heating in a gas-jet plasma characterized using Thomson scattering. A wavelength-tunable ultraviolet (UV) probe laser beam interacts with four intense UV pump beams to drive large-amplitude ion-acoustic waves. For the highest-intensity interactions, the power transfer to the probe laser drops, demonstrating ion-acoustic wave saturation. Over this time, the ion temperature is measured to increase by a factor of 7 during the 500-ps interaction. Particle-in-cell simulations show ion trapping and a subsequent ion heating consistent with measurements. Linear kinetic CBET models are found to agree well with the observed energy transfer when the measured plasma conditions are used.

Abstract
Spore-forming Bacillus sp. has been extensively studied for their probiotic properties. In this study, an acid-treated rice straw hydrolysate was used as carbon source to produce the spores of Bacillus coagulans. The results showed that this hydrolysate significantly improved the spore yield compared with other carbon sources such as glucose. Three significant medium components including rice straw hydrolysate, MnSO4 and yeast extract were screened by Plackett-Burman design. These significant variables were further optimized by response surface methodology (RSM). The optimal values of the medium components were rice straw hydolysate of 27% (v/v), MnSO4 of 0·78 g l-1 and yeast extract of 1·2 g l-1 . The optimized medium and RSM model for spore production were validated in a 5 l bioreactor. Overall, this sporulation medium containing acid-treated rice straw hydrolysate has a potential to be used in the production of B. coagulans spores.

Abstract
OBJECTIVE Several case-control studies have identified the association of the D919G polymorphism of the methionine synthase (MTR) gene with the risk of prostate adenocarcinoma (PRAD). However, the results were inconclusive. MATERIALS AND METHODS Odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs) were evaluated to assess the correlation between MTR D919G variant and PRAD risk. In addition, in silico tools were used to demonstrate the relationship between MTR expression and PRAD risk and survival time. RESULTS The overall results from 10,617 PRAD cases and 40,489 control participants indicated the association of the MTR D919G variant with an increased risk of PRAD (allelic contrast: OR = 1.06, 95% CI = 1.01 - 1.11; GA vs. AA: OR = 1.08, 95% CI = 1.02 - 1.14; GG+GA vs. AA: OR = 1.08, 95% CI = 1.02 - 1.14). The stratified analysis yielded similar results for hospital based studies and those with larger sample sizes. Finally, the in silico results revealed lower MTR expression in PRAD tissue than in normal tissue (transcripts per million = 2.68 vs. 3.34, p<0.05). Furthermore, patients with high MTR expression and Gleason score = 6 exhibited reduced survival time (p<0.0001). CONCLUSIONS Our study indicated that the MTR D919G variant is associated with elevated risk to PRAD, especially for Asian descendants and hospital based studies. Moreover, the MTR D919G variant might be related to PRAD prognosis.

Augmentation is defined as worsening of the symptoms of Restless Legs Syndrome after a brief period of initial improvement with dopaminergic agents resulting in either an earlier onset, increase in severity, quicker onset, spread to other body parts. The exact prevalence of this phenomenon is not known and in patients experiencing augmentation, it can pose a difficult diagnostic and therapeutic challenge to the clinician. In our study, we found extended-release gabapentin to be an effective intervention in patients experiencing dopaminergic augmentation
Methods
This is an open-label single-arm study done in patients exhibiting augmentation while on dopaminergic agents. Patients who were enrolled in the study were initiated on oral extended-release gabapentin(Horizont) 600 mg at 5 pm at the beginning of the study. At day 90, attempts were made to reduce or discontinue dopaminergic agents. International Restless Legs Syndrome-Rating Scale (IRLS) and Augmentation Severity Rating Scale(ASRS) were recorded at each visit.
Results
A total of 10 patients were enrolled in the study while only 8 patients completed it. Compared to the baseline (visit 2), there is a significant improvement in both the augmentation severity(p= 0.0131) and the IRLS (p=0.0497). Wilcoxon matched-pairs signed rank test was used for statistical analysis.
Conclusion
Extended-release Gabapentin is an effective treatment option in primary RLS patients experiencing augmentation secondary to dopaminergic medication usage.
Support
The study is funded and medication is provided by Arbor Pharmaceuticals.

Abstract
Recent national guidelines recommended testing for Mycoplasma genitalium (MG) in clinically-indicated conditions (CIC) including non-gonococcal urethritis (NGU), pelvic inflammatory disease (PID) and epididymo-orchitis. Over five months in 2018 a quality improvement project (QIP) was carried out across three London sexual health clinics with the aim of increasing MG testing rates in CICs. Three Plan-Do-Study-Act (PDSA) cycles were completed: improving IT access, an education event and reminder emails for clinicians who did not test in CIC. To measure testing rates ten patients from each CIC were randomly selected each week and MG testing outcomes were collected. As a balancing measure, we identified the rate of inappropriate MG testing. MG testing rates in patients with NGU increased to 90% following QIP initiation (baseline rate 60%) and this increase was sustained. No increase in MG testing was seen in PID and epididymo-orchitis. Inappropriate MG test rates were high (median of 11%) but remained constant throughout the QIP period. As MG testing is expanding across the UK, we outline a QIP integrating MG testing into a busy multi-site, sexual health service improving testing uptake while not increasing inappropriate testing.
