01). In conclusion, high-purity magnesium implants have the potential to enhance angiogenesis and bone consolidation in the distraction osteogenesis application, and this process might be via the regulation of Von Hippel-Lindau/hypoxia inducible factor-1α/vascular endothelial growth factor signaling.Objective Owing to inconsistency between reports, a meta-analysis was designed to appraise the clinical implications of long non-coding RNAs (lncRNAs) in urine and blood for the diagnosis of bladder cancer. Methods Studies that met the criteria were acquired by bibliographic retrieval through PubMed, Embase, and the Cochrane Library. The pooled diagnostic performance was evaluated by calculating the area under the summary receiver operator characteristic (SROC) curve. The potential sources of heterogeneity were approached through meta-regression and subgroup analyses. All statistical analyses and plots were performed by RevMan 5.3, Meta-DiSc 1.4, and STATA 12.0. Results A total of 43 studies from 15 articles consisting of 3370 bladder cancer patients and 3212 controls were incorporated in our meta-analysis. lncRNAs in urine and blood performed relatively well in diagnosing bladder cancer, with a pooled sensitivity of 0.78, a specificity of 0.79, and an area under the SROC curve (AUC) of 0.86. H19 displayed the best diagnostic accuracy with a pooled AUC of 0.90, followed by UCA1 and MALAT1. The heterogeneity among studies was partly conducted by sample size, lncRNA existence form (cell-free or intracellular lncRNA), lncRNA origin (exosome- or non-exosome-based lncRNA), lncRNA profiling (single- or multiple-lncRNA), specimen types, and ethnicity. Conclusions lncRNAs in urine and blood may serve as noninvasive diagnostic biomarkers with great promise for bladder cancer, while their clinical values need to be examined through further synthetic forward-looking studies.Background Homelessness is a major problem that critically impacts the mental health and well-being of the affected individuals. This umbrella review aimed to evaluate the current evidence on the prevalence of mental disorders among homeless people from evidence-based systematic reviews and meta-analyses. Methods We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Joanna Briggs Institute (JBI) methodology for umbrella reviews. We searched 12 major databases and additional sources to identify systematically conducted reviews and meta-analyses reporting the prevalence of mental disorders among homeless populations. Results We evaluated 1,277 citations and found 15 reviews meeting our criteria. Most studies were conducted among high-income countries with samples from different age groups. Studies reported high prevalence rates of depressive and anxiety disorders, schizophrenia spectrum and psychotic disorders, substance use disorders, suicidal behavior, bipolar and mood disorders, neurocognitive disorders and other mental disorders among homeless people. Moreover, studies also reported a high burden of co-occurring mental and physical health problems among the homeless experiencing mental disorders. Conclusion This umbrella review synthesized the current evidence on the epidemiological burden of mental disorders in homelessness. This evidence necessitates advanced research to explore psychosocial and epidemiological correlates and adopt multipronged interventions to prevent, identify and treat mental disorders among homeless populations.Gymnema sylvestre, a plant typical of India, has long been known for its hypoglycemic effects. The objective of this study was to evaluate the effect of G. sylvestre administration on glycemic control, insulin secretion, and insulin sensitivity in patients with impaired glucose tolerance (IGT). A randomized, double-blind, placebo-controlled clinical trial was conducted in 30 patients with IGT. Fifteen patients randomly received G. sylvestre in doses of 300 mg b.i.d. and the other 15 received placebo in the same way. Before and after the intervention, anthropometric and metabolic measurements were taken, including 2-h oral glucose tolerance test (2-h OGTT), fasting plasma glucose, glycated hemoglobin A1c (A1C), and the lipid profile panel. Areas under the curve of glucose and insulin were calculated, as well as the insulinogenic, Stumvoll, and Matsuda indices. Wilcoxon, Mann-Whitney U, and chi-square or Fisher's exact tests were performed, and a P-value ≤.05 was considered statistically significant. There was a significant reduction in 2-h OGTT (9.1 ± 1.2 vs. 7.8 ± 1.7 mmol/L, P = .003), A1C (5.8 ± 0.3% vs. 5.4 ± 0.4%, P = .025), body weight, body mass index, and low-density lipoprotein cholesterol levels in the G. sylvestre group, with an increment in the Matsuda index (1.8 ± 0.8 vs. 2.4 ± 1.2, P = .008). At the end of the intervention, 46.7% of the patients obtained normal values in A1C. In conclusion, G. sylvestre administration in patients with IGT decreased 2-h OGTT and A1C, increasing insulin sensitivity. There were also improvements in anthropometric measures and the lipid profile.Background Inhalation therapy is a cornerstone of treating patients with chronic obstructive pulmonary disease (COPD). Inhaler types and through-device inhalation parameters influence airway drug delivery. We aimed to measure the repeatability of inhalation performance through four different commercially available inhalers. Methods We recruited control subjects (n = 22) and patients with stable COPD (S-COPD, n = 16) and during an acute exacerbation (AE-COPD, n = 15). Standard spirometry was followed by through-device inhalation maneuvers using Ellipta®, Evohaler®, Respimat®, and Genuair®. Through-device inspiratory vital capacity (IVCd) and peak inspiratory flow (PIFd), as well as inhalation time (tin) and breath hold time (tbh), were recorded and all measurements were repeated in a random manner. Results There was no difference in forced expiratory volume in 1 second (FEV1) between patients (S-COPD 39 ± 5 vs. AE-COPD 32% ± 5% predicted, p > 0.05). In controls, the IVCd was significantly reduced by all four drugs.Purpose To evaluate the availability of fertility preservation (FP) services and educational resources on the websites of top-ranked U.S. pediatric cancer programs. Methods Cross-sectional survey of information and resources related to FP on websites from top-ranked pediatric cancer programs according to the 2018-2019 U.S.-News & World Report (USNWR) ranking. Factors that predicted the website availability of FP information or a fertility team were analyzed, as was availability in Spanish and for specific groups by sex and puberty status. As a surrogate marker of comprehensive oncological services, the availability of resources for psychological support was compared to FP. Results A fertility team was referenced on the website of 36% of programs, but only 32% provided FP educational resources for patients. Among them, 100%, 93.8%, 93.8%, and 68.8% provided specific information for postpubertal females, prepubertal females, postpubertal males, and prepubertal males, respectively. The majority (93.8%) did not provide information in Spanish. The ranking on USNWR (p less then 0.05) and patient volume (p less then 0.05) positively correlated with the availability of FP information and fertility team on the program's website. Information regarding psychological support was provided more often than information regarding FP (96% vs. 32%, p less then 0.05). Conclusion The majority of the top-ranked pediatric cancer programs in the United States do not list FP resources or a fertility team on their website. The lack of resources is particularly concerning for the Spanish-speaking population, as well as for prepubertal males. This may be potentially hindering access to FP and contributing to health care disparities.Aim Sepsis is a significant cause of mortality and morbidity in the NICU despite the potent armamentarium of antibiotics. Recently, there has been a considerable increase in antimicrobial resistance even to high-end 3rd line antibiotics. Thus, there is a need to look into adjunctive therapies. This study aims to study the role of double volume exchange transfusion (DVET) in reducing mortality due to severe sepsis.Methods All neonates with severe sepsis admitted in NICU from January 2017 to September 2019 were included in the study. Seven neonates who met inclusion criteria and received DVET were compared to 21 gestation and severity matched controls, who received standard therapy (ST) alone. The primary outcome studied was mortality before discharge in both the groups. Other results analyzed were the incidence of persistent thrombocytopenia and refractory shock.Results There was a significant reduction in mortality in the intervention group (57% vs. 71% (p = .004). There was also a significant reduction both in the incidence of refractory shock (71% vs. 75%; p = .01) and persistent thrombocytopenia (86% vs. 65%; p = .03) in the DVET group. No significant adverse effects occurred following DVET.Conclusions In neonates with severe sepsis, DVET may be a useful adjunct therapy. It may reduce mortality and decreased the incidence of refractory shock and thrombocytopenia. DVET is a safe procedure in severely sick and septic neonates.Dendritic cells (DCs) and monocytes are key immunoregulatory cells that link the innate and adaptive immune response. However, understanding of human cell-specific responses to different doses of stimuli including lipopolysaccharide (LPS) is limited. This study investigated the monocyte and classical DC (cDC)-specific, as well as the overall inflammatory response after exposure to varying doses of LPS. Dovitinib in vivo Fresh peripheral whole blood (n = 8) was used in an in vitro peripheral blood culture model to assess cDC and monocyte responses in coculture with varying doses of LPS (0.25, 0.5, 0.75, 1 μg/mL). cDC and monocyte cytokine responses were measured through flow cytometry. Supernatants collected from the in vitro model were used in a cytometric bead array to assess the overall inflammatory response. Exposure to all doses of LPS tested increased monocyte, cDC, and the overall leukocyte response. A dose-dependent reduction in cDC and monocyte cytokine production was also evident with higher LPS doses. This study demonstrates that cell-subset-specific responses are more susceptible to LPS exposure compared with the overall inflammatory response. Therefore, assays that assess cell-specific immune responses may be more beneficial to identify underlying pathophysiology of infection and inflammation.Purpose Effects of a mindfulness-based (MB) yoga practice on stress, burnout, and indicators of well-being among nurses and health care professionals (HCPs). Design A randomized controlled trial, 80 HCPs assigned to either MB yoga intervention or control group. Method The MB yoga intervention group (n = 41) attended weekly yoga classes and practiced yoga independently. The control group (n = 39) did not receive the yoga intervention. Study participants completed pre- and postintervention questionnaires, instruments included (a) Perceived Stress Scale; (b) Maslach Burnout Inventory; (c) Vitality subscale of the Medical Outcomes Study Short Form-36; (d) Global Sleep Quality item, (e) Mindfulness Awareness Survey, and (f) subscale of the Brief Serenity Scale. Diurnal salivary cortisol and blood pressure were assessed pre and postintervention. Results Significant improvements (p less then .01) noted in MB yoga compared with control for self-reported factors, including stress (Perceived Stress Scale), burnout (Maslach Burnout Inventory), vitality (Medical Outcomes Study Short Form-36), sleep (GSQ), serenity/inner haven (IH), and mindfulness (Mindfulness Awareness Survey).
