To determine the usefulness of hsa-miR-346, a potential biomarker enhancing the activity of non-tuberculous mycobacterial diseases, as a biomarker of tuberculosis activity.

We investigated whether hsa-miR-346 is secreted by human macrophages infected with Mycobacterium tuberculosis (M. tuberculosis) in an in vitro study. In addition, a cross-sectional study was conducted first to evaluate whether serum hsa-miR-346 is elevated in patients with tuberculosis compared with that in healthy individuals. Second, we conducted a retrospective study to evaluate whether anti-tuberculosis treatment reduces serum hsa-miR-346 levels.

Log hsa-miR-346 levels were significantly elevated in the supernatant of human macrophages infected with M. tuberculosis in a dose-dependent manner. The mean serum log hsa-miR-346 levels were -15.48 (-15.76 to -15.21) in patients with tuberculosis and -16.12 (-16.29 to -15.95) in healthy volunteers, which significantly differed. In addition, hsa-miR-346 significantly decreased at 2 months from starting an anti-tuberculosis treatment.

We consider hsa-miR-346 as a potential biomarker enhancing the tuberculosis activity.

Methods to reduce time to culture positivity (TTP) are urgently required. We determined if growth factor supplementation in the mycobacterial growth indicator tube (MGIT) culture system reduces TTP. MGITs were supplemented with fresh culture filtrate (CF) as a source of growth stimulatory molecules from axenic Mycobacterium tuberculosis culture. Different volumes of CF and media components were tested. The performance of these modified MGITs was assessed with sputum from HIV-TB co-infected individuals. Reducing the volume of MGIT cultures and removal of detergent from cultures grown to generate CF had a marginal but significant benefit on reducing TTP. In a subset of specimens, CF inhibited growth. CGS 21680 Following optimization of methods, a reduced TTP occurred in specimens with low bacillary load as measured by GeneXpert, smear microscopy and colony forming units. Three specimens that were negative under standard conditions flagged positive following CF supplementation. Our data provide preliminary evidence that addition of CF to MGIT cultures can enhance detection of M. tuberculosis in HIV-TB co-infected patients with low sputum bacillary loads.
Gut colonization with antibiotic-resistant bacteria (ARB) is associated with a significantly decreased overall survival in adult patients undergoing allo-HCT because of an increased treatment-related mortality.

The objective of this multicenter study was the analysis of impact of gut colonization status and the use of antibiotics on development of gastro-intestinal (GI) graft-versus-host disease (GVHD) of allo-HCT in children.

All consecutive patients who underwent allo-HCT over a period of three years in all pediatric HCT centers in Poland were analyzed for the impact of gut colonization on GI GVHD, with respect to standard of care including prophylaxis of infections and supportive therapy.

At the time of allo-HCT, 44.2% of pediatric patients were colonized by ARB. Decontamination therapy with antibiotics was applied in 78% of children. Gut decontamination prophylactic therapy with antibiotics decreased the risk of acute GI GVHD. The use of gentamicin contributed to decreased rate of GVHD, while the use of ciprofloxacin and colistin contributed to increased incidence of GVHD after allo-HCT in children. Sepsis with ARB and non-MFD transplant contributed significantly to worse survival, while neither colonization nor gut decontamination had an impact on overall survival.

Gut decontamination therapy contributed to lower incidence of acute GI GVHD in children undergoing allo-HCT, and the use of specific antibiotics might be responsible for this effect.

However, the inconsistent efficacy/safety of nanomedicines in cancer patients versus preclinical cancer models have provoked debate for nanomedicine design criteria. In this study, we investigate nanomedicine design criteria in three types of preclinical cancer models using five clinically used nanomedicines, which identifies the factors for better clinical translations of their observed clinical efficacy/safety compared to free drug or clinical micelle formulation. When those nanomedicines were compared with drug solution or clinical micelle formulation in breast tumors, long and short-circulating nanomedicines did not enhance tumor accumulation by EPR effect in transgenic spontaneous breast cancer model regardless of their size or composition, although they improved tumor accumulations in subcutaneous and orthotopic breast cancer models. However, when tumors were compared to normal breast tissue, nanomedicines, drug solution and clinical micelle formulation showed enhanced tumor accumulation regardless of the breast cancer models. In addition, long-circulating nanomedicines did not further increase tumor accumulation in transgenic mouse spontaneous breast cancer nor universally decrease drug accumulations in normal organs; they decreased or increased accumulation in different organs, potentially changing the clinical efficacy/safety. In contrast, short-circulating nanomedicines decreased blood concentration and altered drug distribution in normal organs, which are correlated with their clinical efficacy/safety. A reappraisal of current nanomedicine design criteria is needed to ensure consistent clinical translation for improvement of their clinical efficacy/safety in cancer patients.To assess whether the follicle-stimulating hormone (FSH) subunits observed in patients with gonadotroph adenomas (GA) can cause infertility, the effects of subunits and heterodimeric FSH on the in vitro follicle development were evaluated in mice. The partial forms of FSH in follicle culture did not induce development into pseudoantral follicles, whereas follicles cultured with native FSH developed into pseudoantral follicles and produced mature metaphase II oocyte. Therefore, intact FSH is needed for folliculogenesis, implying that production of FSH with a partial structure in GA may result in infertility.
This study analyzed the predictive validity of the Center for Epidemiologic Studies Depression (CES-D) scale for late-life depression (LLD) over the age of 50 years and identified the usefulness of the CES-D compared with the Geriatric Depression Scale (GDS).

Electronic searches were performed on the MEDLINE, EMBASE, CINAHL, and PsycINFO databases using the following keywords depression, depressive disorder, major, and the CES-D scale. The Quality Assessment of Diagnostic Accuracy Studies-2 was applied to assess the risk of bias.

We reviewed 22 studies, including 27,742 older adults aged 50+ years that met the selection criteria. In the meta-analysis, the pooled sensitivity was 0.81 in the CES-D long version and 0.76 in the short version. The sROC AUC was 0.89 (SE=0.01) for the long version and 0.88 (SE=0.04) for the short version. The GDS was only compared to the CES-D long version. The pooled sensitivity was as follows the CES-D, 0.82; the GDS long version, 0.86; and the GDS short version, 0.87. Further, there was no heterogeneity of 0.0% between studies. The pooled specificity was 0.78 and 0.77, respectively, and the sROC AUC was 0.88 for the CES-D (SE=0.02), 0.89 for the GDS long version (SE=0.04), and 0.91 for the GDS short version (SE=0.03).

We could not consider cognitive function of older adults.

The CES-D showed similar predictive validity compared to the GDS developed in older adults. The CES-D is a useful tool that can be used for LLD screening in older adults over 50 years old.

Patients diagnosed with lung cancer have a higher suicide rate than the general population and other cancer patients. The aim of this study was to develop and validate a prediction model for the individual risk for suicide after the diagnosis of lung cancer.

Patients diagnosed with lung cancer between 2007 and 2016 were selected from the Surveillance, Epidemiology, and End Results (SEER) database and randomly divided into training and validation cohorts. Cox proportional hazard models were used to identify relevant predictors and construct prediction models. Additionally, graphic visualization methods were used to predict the risk for suicide within 5 years after the diagnosis of lung cancer. We used bootstrapping for the internal validation, Harrell's C-index for the discrimination, and a calibration plot for the calibration of the proposed model.

We obtained complete information on 112372 patients diagnosed with lung cancer from the SEER cohort. Multivariate Cox regression identified sex, race, marital status, tumour grade, surgery, radiation, and chemotherapy as significant predictors for suicide. link3 A nomogram and a risk matrix were developed to visualize the risk for suicide within 5 years after lung cancer diagnosis. The bootstrapped and validated C-indices of the nomogram were 0.77 and 0.78, respectively. The calibration plot indicated good agreement between the prediction and actual observation.

The proposed model demonstrated good discrimination and calibration performance for predicting the risk for suicide within 5 years after lung cancer diagnosis. Reliable and feasible risk assessment tools can be promising for preventing unnecessary suicides among lung cancer patients.

Cerebral small vessel disease (CSVD) and neurodegeneration may be involved in the development and persistence of late-life depressive symptoms, but longitudinal evidence is scarce. We investigated the longitudinal associations of markers of CSVD and brain atrophy with incident depressive symptoms and the course of depressive symptoms, above and below 60 years of age.

White matter hyperintensity volumes (WMH), presence of lacunar infarcts and cerebral microbleeds, and white matter, grey matter, and cerebral spinal fluid volumes were assessed at baseline by 3T MRI in The Maastricht Study (mean age 59.5±8.5 years, 49.6% women, n=4,347; 16,535 person-years of follow-up). Clinically relevant depressive symptoms (9-item Patient Health Questionnaire≥10) were assessed at baseline and annually over seven years. We used Cox regression and multinomial logistic regression analyses adjusted for demographic, cardiovascular, and lifestyle risk factors.

Above 60 years of age, larger WMH volumes were associated with an increased risk for incident depressive symptoms (HR[95%CI]1.
