Establishing clinical idea models whenever adhering to minimum trial size advice: The need for quantifying bootstrap variability in adjusting variables along with predictive performance.
Differentiating between diabetic kidney disease (DKD) and non-diabetic kidney disease (NDKD) in patients with Type 2 diabetes mellitus (T2DM) is important due to implications on treatment and prognosis. Clinical methods to accurately distinguish DKD from NDKD are lacking. We aimed to develop and validate a novel nomogram to predict DKD in patients with T2DM and proteinuric kidney disease to guide decision for kidney biopsy.

A hundred and two patients with Type 2 Diabetes Mellitus (T2DM) who underwent kidney biopsy from 1st January 2007 to 31st December 2016 were analysed. Univariate and multivariate analyses were performed to identify predictive variables and construct a nomogram. The discriminative ability of the nomogram was assessed by calculating the area under the receiver operating characteristic curve (AUROC), while calibration was assessed using the Hosmer-Lemeshow goodness-of-fit test and calibration plot. Internal validation of the nomogram was assessed using bootstrap resampling.

Duration of T2DM, HbA1c, absence of hematuria, presence ofdiabetic retinopathy and absence ofpositive systemic biomarkers were found to be independent predictors of DKD in multivariate analysis and were represented as a nomogram. The nomogram showed excellent discrimination, with a bootstrap-corrected C statistic of 0.886 (95% CI 0.815-0.956). Both the calibration curve and the Hosmer-Lemeshow goodness-of-fit test (p = 0.242) showed high degree of agreement between the prediction and actual outcome, with the bootstrap bias-corrected curve similarly indicating excellent calibration.

A novel nomogram incorporating 5 clinical parameters is useful in predicting DKD in type 2 diabetes mellitus patients with proteinuric kidney disease.

However, multiple hurdles still exist for the effective utilization of hiPSC-CMs as a human-based experimental platform that can be an alternative to the current animal models. To further expand their potential as a research tool and bridge the translational gap, we have generated a cardiac-specific hiPSC reporter line that differentiates into fluorescent CMs using CRISPR-Cas9 genome editing technology. The CMs illuminated with the mScarlet fluorescence enable their non-invasive continuous tracking and functional cellular phenotyping, offering a real-time 2D/3D imaging platform. Utilizing the reporter CMs, we developed an imaging-based cardiotoxicity screening system that can monitor distinct drug-induced structural toxicity and CM viability in real time. The reporter fluorescence enabled visualization of sarcomeric disarray and displayed a drug dose-dependent decrease in its fluorescence. The study also has demonstrated the reporter CMs as a biomaterial cytocompatibility analysis tool that can monitor dynamic cell behavior and maturity of hiPSC-CMs cultured in various biomaterial scaffolds. This versatile cardiac imaging tool that enables real time tracking and high-resolution imaging of CMs has significant potential in disease modeling, drug screening, and toxicology testing.
The significant roles of circular RNAs (circRNAs) in different cancers and diseases have been reported. We now focused on the possible role of a newly recognized circRNA, circ_0004674 in triple-negative breast cancer (TNBC), and the related downstream mechanism.

The expression of circ_0004674 in TNBC tissues and cells was determined followed by analysis of the correlation between circ_0004674 and TNBC patients' prognosis. The interaction between circ_0004674, miR-377-3p, E2F6, and PNO1 was then identified using bioinformatics analysis combined with FISH, RIP, RNA pull-down, RT-qPCR, and Western blot analysis. Using gain-of-function and loss-of-function methods, we analyzed the effect of circ_0004674, miR-377-3p, E2F6, and PNO1 on TNBC in vivo and in vitro.

Increased circ_0004674 and E2F6 but decreased miR-377-3p were observed in TNBC tissues and MDA-MB-231 TNBC cells, all of which findings were associated with poor prognosis in patients with TNBC. Silencing of circ_0004676 remarkably suppressed the prolrcinogenic effect of circ_0004676 on TNBC through regulation of the miR-377-3p/E2F6/PNO1 axis. 1. Circ_0004674 is highly expressed in TNBC tissues and cells. 2. Circ_0004674 upregulates the expression of E2F6 by sponging miR-377-3p. 3. E2F6 upregulates PNO1 by binding to the PNO1 promoter. 4. GGTI 298 Circ_0004674 favors TNBC progression by regulating the miR-377-3p/E2F6/PNO1 axis. 5. This study provides a new target for the treatment of TNBC.Interpersonal-motivational models posit that heightened avoidance of aversive social stimuli and diminished approach of appetitive social stimuli increases social withdrawal and reduces positive social interactions, thereby increasing risk for future social anxiety and depression. The current study examined if approach-avoidance biases toward angry and happy faces, measured during the Approach Avoidance Task (AAT), would be associated with the development of adolescent depressive and social anxiety symptoms. At baseline, participants included 129 never-depressed adolescent girls (ages 11-13), two-thirds of whom were at high-risk for internalizing problems due to shy/fearful temperament. Girls reported their depressive and social anxiety symptoms every 6 months for 24 months and completed the AAT at baseline and 24-mo follow-up. Heightened avoidance bias toward angry faces at baseline predicted increases in depressive symptoms across the follow-up, even after accounting for temperament and pubertal status. In contrast, girls with greater depression and social anxiety symptoms at 24-mo follow-up exhibited less avoidance bias for angry faces at the same time point. Findings suggest that avoidance behaviors (i.e., avoiding people or settings associated with angry faces, which are often perceived as hostile, critical, or rejecting) may be a risk factor for depression, above and beyond risk imparted by temperament or advances in puberty. However, with increasing internalizing symptoms, it may become more difficult for adolescents to maintain avoidance for aversive social stimuli, and without the introduction of more adaptive emotion regulation strategies, these biases may continue to increase and maintain risk for internalizing problems.This study examined gender-specific longitudinal pathways from harsh parenting through rumination to anxiety and depression symptoms among early adolescents from three countries and six subgroups. Participants were 567 mothers, 428 fathers, and 566 children (T1 Mage = 10.89; 50% girls) from Medellín, Colombia (n = 100); Naples, Italy (n = 95); Rome, Italy (n = 99); Durham, North Carolina, United States (Black n = 92, Latinx n = 80, and White n = 100). Parent reported maternal and paternal harsh parenting were measured at T1. Adolescent reported rumination was measured at T2 (Mage = 12.58) and anxiety and depression symptoms were measured at T1 and T3 (Mage = 13.71). Rumination mediated the pathway from maternal harsh discipline to girls' anxiety and depression symptoms, controlling for baseline anxiety and depression symptoms. The more harsh discipline mothers used, the more their daughters ruminated, which in turn was associated with increased anxiety and depression symptoms. Exploratory moderated mediation analyses indicated that the strength of the mediational pathway from maternal harsh discipline through girls' rumination to anxiety and depression symptoms decreased as the normativeness of harsh parenting increased. Mediational pathways for boys and for paternal harsh discipline were not significant. Our findings expand knowledge on specific contexts in which rumination is a mechanism for understanding pathways to anxiety and depression symptoms.Failure Mode and Effects Analysis (FMEA) is one of the most used methods in risk assessment and prioritization. This study was conducted to identify, evaluate, prioritize, and analyze risks associated with the physical processes of Sahand municipal wastewater plant using traditional and fuzzy FMEA methods. The present research was a cross-sectional analytical study that was conducted to prioritize the risks of unit operations of screening and grit removal in Sahand municipal wastewater treatment plant for 6 months. First, a team of five experts was formed and the traditional FMEA worksheet was completed. Then, the fuzzy membership functions were determined according to experts' opinions and using the MATLAB program, and the severity, occurrence, detection, and risk priority number (RPN) became fuzzy and risks were prioritized according to the fuzzy logic outputs. A total of 53 failure modes were identified for screening (26 failures) and grit removal units (27 failures) using the traditional FMEA risk assessmssessment and fuzzy models leads to more realistic results, as well as corrective action prioritization is better performed.
Fatigue is a highly prevalent and disabling symptom in cancer survivors. Although many measures have been developed to assess survivors' fatigue, their ability to accurately capture change following intervention has rarely been assessed in post-treatment survivors. Ultra-brief fatigue measures are preferable in clinical practice but have limited evidence supporting their use with cancer survivors. We examined the psychometric properties of four Fatigue Symptom Inventory (FSI) measures, including the new FSI-3, in cancer survivors. Examined properties included responsiveness to change and minimally important differences (MIDs).

We analyzed data from three randomized controlled trials with post-treatment cancer survivors (N = 328). Responsiveness to change was evaluated by comparing standardized response means for survivors who reported their fatigue as being better, the same, or worse at 2-3months. Responsiveness to intervention was assessed via effect sizes, and MIDs were estimated by using several methods. We also computed area under the curve (AUC) values to assess FSI measures' discriminative accuracy compared to an established cut-point.

All FSI measures differentiated survivors who reported improvement at 2-3months from those with stable fatigue, but did not uniformly differentiate worsening fatigue from stable fatigue. Measures showed similar levels of responsiveness to intervention, and MIDs ranged from 0.29 to 2.20 across FSI measures. AUC analyses supported the measures' ability to detect significant fatigue.

Four FSI scales show similar responsiveness to change, and estimated MIDs can inform assessment of meaningful change in fatigue. The FSI-3 shows promise as an ultra-brief fatigue measure for survivors.

The Pi/PPi ratio is thought to be controlled by two ecto-phosphatases present on the outer leaflet of the MVs' membrane ectonucleotide pyrophosphatase/phosphodiesterase 1 (NPP1) that produces PPi as well as Pi from ATP and tissue-nonspecific alkaline phosphatase (TNAP) that hydrolyzes both ATP and PPi to generate Pi. However, if and how these enzymes act in concert in MVs are still unclear. Herein, we investigated the role of NPP1 and TNAP in ATP hydrolysis during MV-mediated biomineralization using proteoliposomes as a biomimetic model for MVs. Proteoliposomes composed by 1,2-dipalmitoylphosphatidylcholine (DPPC) and harboring NPP1 alone, TNAP alone, or both together at different molar ratios (11, 101, and 110) were fabricated.
