Patients undergoing gynecological surgery commonly receive indwelling transurethral Foley catheters, however duration of catheterization is associated with risk of urinary tract infections and other ...adverse effects. Early removal of catheters is encouraged, however optimal timing postsurgery remains unclear. This quasi-experimental study compared outcomes for women after removal of a Foley catheter at two different times following benign gynecological surgery. Participants received either early catheter removal, within 6 hours of surgery (n = 38) or standard catheter removal, within 12 to 24 hours of surgery (n = 45). There were no significant differences in outcomes for discomfort scores or re-catheterization rates between groups. However, the early removal group had a significantly shorter time to first ambulation and shorter hospital stays. Early removal of Foley catheters in patients who underwent gynecological surgery did not increase adverse events. Early removal of catheters after gynecological surgery may decrease re-catheterization rates and increase patient satisfaction.
We present the first comprehensive analysis of Mycobacterium tuberculosis (MTB) isolates circulating in southern Taiwan. In this 9-year population-based study, the TB situation in the Kaohsiung ...region was characterized by genotypic analysis of 421 MTB isolates.
All 421 isolates of MTB were analyzed by spoligotyping and MIRU-VNTR typing. Drug-resistance patterns were also analyzed.
The percentage of EAI (East African-Indian) strains increased across sampling years (2000-2008) in southern Taiwan, whereas the proportion of Beijing lineages remained unchanged. Clustering was more frequent with EAI genotype infections (odds ratio = 3.6, p<0.0001) when compared to Beijing genotypes. Notably, MTB resistance to streptomycin (STR) had significantly increased over time, but resistance to other antibiotics, including multidrug resistance, had not. Three major genes (gidB, rpsL and rrs) implicated in STR resistance were sequenced and specific mutations identified.
This study revealed that EAI strains were highly transmissible and that STR resistance has increased between 2000 and 2008 in Kaohsiung, Taiwan.

BLI-02,

TYCA06, isolated from healthy breast milk, miso, and the healthy human gut, were assessed for safety in this study. BLI-02, LPL28, TYCA06, and ET-66 exhibited no ...antibiotic resistance and mutagenic activity in the Ames test at the highest dosage (5000 μg/plate). No genotoxicity was observed in micronucleus and chromosomal aberration assays in rodent spermatogonia at the maximum dosage of 10 g/kg body weight (BW). No acute and sub-chronic toxicity occurred in mice and rats at the maximum tested dosage of 10 g/kg BW and 1.5 g/kg BW, respectively. The lyophilized powder of these strains survived a low pH and high bile salt environment, adhering strongly to Caco-2 cells. Unique antimicrobial activities were noted in these strains, with BLI-02 demonstrating the best growth inhibition against
, LPL28 exhibiting the best growth inhibition against
, and ET-66 showing the best growth inhibition against
. Based on the present study, the lyophilized powder of these four strains appears to be a safe probiotic supplement at tested dosages. It should be applicable for clinical or healthcare applications.
Muscle wasting is highly prevalent in patients with chronic kidney disease (CKD). However, the assessment of skeletal muscle mass and strength in clinical settings is not commonly available. We aimed ...to evaluate the feasibility of serum creatinine/cystatin C (Cr/CysC) ratio in the assessment of muscle wasting.
In 272 patients with CKD aged 66.5 ± 15.1 years, skeletal muscle mass and handgrip strength (HGS) were assessed. Skeletal muscle index (SMI) was calculated as skeletal muscle mass/height2. Low muscle mass was defined as SMI below the sex-specific 10th percentile of study population and low handgrip strength as less than 26 Kg for men and 18 Kg for women.
The Cr/CysC ratio was significantly lower in both the low SMI and low HGS groups. Moreover, the Cr/CysC ratio correlated with SMI (r = .306, p < .001) and HGS (r = .341, p < .001). After adjusting for confounding factors, age, sex, waist circumference, body fat mass, and Cr/CysC ratio were independently associated with SMI, whereas age, sex, diabetes, hemoglobin, estimated glomerular filtration rate, urine protein/creatinine ratio, SMI, and Cr/CysC ratio were independently associated with HGS.
Cr/CysC ratio appears to be a promising surrogate marker for detecting muscle wasting in patients with CKD. Further studies are needed to extend our findings.
A silver nanoparticle (AgNP)-based sandwich-type lateral flow immunoassay (LFIA) was evaluated for rapid detection of Staphylococcal enterotoxin B (SEB) in milk and honey. The role of trisodium ...citrate dihydrate (TSC) in the formation of Ag/TSC nanoparticles was established using UV–Vis spectroscopy. The association of silver with TSC in Ag/TSC nanoparticles was studied by the decrease in the intensity of anodic peak potential at 0.47 V and shift to 0.30 V in cyclic voltammetry (CV). The morphological, compositional and interaction studies of the AgNPs conjugated with the anti-SEB polyclonal antibody (Ag-sAb) was established using transmission electron microscopy (TEM) and X-ray photo electron spectroscopy (XPS) measurements. The visible detection limit and optical detection limit of the SEB test strip were 0.5 and 0.125 ppm, respectively, in SEB standard solution. This assay showed no cross-reaction with Staphylococcal enterotoxin A, Staphylococcal enterotoxin C or Salmonella typhi. Finally, the SEB test strip was effectively applied for the detection of SEB in spiked liquid milk and viscous honey, with optical detection limits of 0.25 and 0.5 ppm, respectively.

The relevance between circulating metabolites and vascular events remains controversial and comprehensive studies are lacking. We sought to investigate the prospective associations of plasma ...metabolomics with risks of incident stroke, ischemic stroke (IS), hemorrhagic stroke (HS), and myocardial infarction (MI). Within the UK Biobank cohort, 249 circulating metabolites were measured in 90 438 participants without baseline vascular diseases. Cox proportional hazards regressions were applied to estimate adjusted hazard ratios (HRs) for per 1 standard deviation increment in metabolites. The least absolute shrinkage and selection operator algorithm was used for selecting metabolite subsets. During a median of 9.0 years of follow‐up, we documented 833 incident stroke and 1256 MI cases. Lipid constituents, comprising cholesterol, cholesteryl esters, free cholesterol, phospholipids, and total lipids, in very low‐ (VLDL), intermediate‐ (IDL), and low‐density lipoprotein (LDL) particles were positively associated with MI risk (HR = 1.12 to 1.36; 95% CI = 1.06 to 1.44), while in high‐density lipoprotein (HDL) particles showed inverse associations (HR = 0.68 to 0.81; 95% CI = 0.63 to 0.87). Similar association pattern with MI was also observed for VLDL, IDL, LDL, and HDL particles themselves. In contrast, triglycerides within all lipoproteins, including most HDL particles, were positively associated with MI risk (HR = 1.14 to 1.28; 95% CI = 1.08 to 1.35) and, to a slightly lesser extent, with stroke and IS. Unsaturation of fatty acids and albumin were inversely associated with risks of stroke, IS, and MI. In contrast, the linear association for HS is absent. When combining multiple metabolites, the metabolite risk score captured a drastically elevated risk of all vascular events, about twice that of any single metabolite. Taken together, circulating metabolites showed remarkably widespread associations with incident MI, but substantially weakened associations with risks of stroke and its subtypes. Exhaustive metabolomics profiling may shed light on vascular risk prediction and, in turn, guide pertinent strategies of intervention and treatment.
Lipoprotein lipids and other circulating metabolites related to risks of incident MI, stroke, and IS. Multiple lipid constituents within VLDL, IDL, and LDL particles were positively related to MI risk, comprising cholesterol, cholesteryl esters, free cholesterol, phospholipids, and total lipids. Nevertheless, these lipid constituents within HDL particles showed inverse associations. In contrast, triglycerides within all lipoproteins were positively associated with MI risk. These associations were substantially weaker for stroke and IS. Glycoprotein acetyls were positively associated with incident stroke and MI, while unsaturation of fatty acids and albumin displayed inverse associations with stroke, IS, and MI.
