A Study of the Effectiveness of Mobile Health Application in A Self-management Intervention for Kidney Transplant Patients.

INTRODUCTION: With the development of information technology in medical treatment, mobile medical treatment has become a new way to seek treatment, follow-up, extended care, popular science, disease prevention and access to disease expertise. The application of mobile medical treatment is relatively mature in the management of chronic diseases. Currently, mobile medical intervention is also introduced in the self-management of patients after Renal Transplantation. Compared with traditional intervention methods, mobile medical treatment has the advantages of convenience, speed, low cost and no geographical restriction, and it is easy to be used by KT recipients in self-management and has good feasibility. Therefore, we conducted self-management intervention for patients after Renal Transplantation based on mobile medical procedures, so as to improve patients' satisfaction, medication compliance, follow-up rate, and ease patients' anxiety about the disease. METHODS: A total of 160 discharged patients with stable recovery of transplanted Renal function who underwent renal transplantation surgery in our hospital from January 2021 to January 2023 were selected for retrospective analysis. According to the different intervention plan, the patients were divided into the intervention group and the comparison group, 80 cases each. Among them, the intervention group used the mobile medical application selfmanagement behavior intervention, and the comparison group used the conventional self-management behavior intervention. The differences of self-management behavior score, quality of life score, Basel score and anxiety score between the two groups of patients after Renal Transplantation were analyzed and compared. RESULTS: After intervention, there were statistically significant differences in the scores of self-management behavior scale, Quality of life related rating scale, Basel Assessment scale and Self-rating Anxiety Scale between the intervention group and the control group (P < .05). CONCLUSION: Mobile health intervention tools can provide efficient, comprehensive and accurate remote health intervention and professional support for patients, optimize the medical service system, and meet the social medical needs of high-quality nursing services.  DOI: 10.52547/ijkd.7693.

Systematic review and meta-analysis of candidate gene association studies of benign prostate hyperplasia.

BACKGROUND: Benign prostate hyperplasia (BPH) is the most common urological problem in elderly males. Recent studies have reported polymorphism in various metabolic genes in BPH. However, their association with the susceptibility of BPH is still inconsistent. Here, we systematically reviewed and performed a meta-analysis of CYP17, VDR, and ACE genes to determine their precise association with the risk of BPH. METHODS: A comprehensive literature search for published studies on candidate gene associations involving vitamin D receptor (VDR), angiotensin-converting enzyme (ACE), and CYP17 genes with the risk of BPH was done up to April 2020 in PubMed, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar databases. Fixed/random effects models were used to estimate the odd's ratio (OR) and 95% confidence intervals (CIs). Begg's funnel plot was used to assess the potential for publication bias. RESULTS: We found a total of 23 studies containing 3461 cases and 3833 controls for these gene polymorphisms. A significant association of ACE gene polymorphism was observed under the recessive (II vs. ID + DD) model for BPH susceptibility compared to control subjects (overall OR = 1.67, 95% CI = 1.03-2.73). Similar trends were observed for ACE gene polymorphism in Caucasian (OR = 6.18, 95% CI = 1.38-27.68) and Asian (OR = 1.42, 95% CI = 0.99-2.03) populations under study. No significant association was observed in VDR and CYP17 gene polymorphisms in any dominant or recessive models. CONCLUSION: Significant OR demonstrated the implication of ACE gene polymorphism in the proliferation of prostate tissue, which in turn is associated with BPH susceptibility. However, prospective studies at large scale and sample size are needed to confirm the current findings.

Metal-Organic Layers Leading to Atomically Thin Bismuthene for Efficient Carbon Dioxide Electroreduction to Liquid Fuel.

Electrochemical reduction of CO2 to valuable fuels is appealing for CO2 fixation and energy storage. However, the development of electrocatalysts with high activity and selectivity in a wide potential window is challenging. Herein, atomically thin bismuthene (Bi-ene) is pioneeringly obtained by an in situ electrochemical transformation from ultrathin bismuth-based metal-organic layers. The few-layer Bi-ene, which possesses a great mass of exposed active sites with high intrinsic activity, has a high selectivity (ca. 100 %), large partial current density, and quite good stability in a potential window exceeding 0.35 V toward formate production. It even deliver current densities that exceed 300.0 mA cm-2 without compromising selectivity in a flow-cell reactor. Using in situ ATR-IR spectra and DFT analysis, a reaction mechanism involving HCO3 - for formate generation was unveiled, which brings new fundamental understanding of CO2 reduction.

Ligand-assisted capping growth of self-supporting ultrathin FeNi-LDH nanosheet arrays with atomically dispersed chromium atoms for efficient electrocatalytic water oxidation.

Self-supporting ultrathin FeNi-layered double hydroxide nanosheet arrays with atomically dispersed Cr atoms were firstly fabricated from stainless steel mesh by a facile ligand-assisted capping growth approach. Their unique nanostructure and a strong synergetic effect between the atomically dispersed Cr dopants and the active sites afford an exceptional OER activity.

Gastrin-releasing peptide contributes to the regulation of adult hippocampal neurogenesis and neuronal development.

In the postnatal hippocampus, newly generated neurons contribute to learning and memory. Disruptions in neurogenesis and neuronal development have been linked to cognitive impairment and are implicated in a broad variety of neurological and psychiatric disorders. To identify putative factors involved in this process, we examined hippocampal gene expression alterations in mice possessing a heterozygous knockout of the calcium/calmodulin-dependent protein kinase II alpha heterozygous knockout gene (CaMK2α-hKO), an established model of cognitive impairment that also displays altered neurogenesis and neuronal development. Using this approach, we identified gastrin-releasing peptide (GRP) as the most dysregulated gene. In wild-type mice, GRP labels NeuN-positive neurons, the lone exception being GRP-positive, NeuN-negative cells in the subgranular zone, suggesting GRP expression may be relevant to neurogenesis and/or neuronal development. Using a model of in vitro hippocampal neurogenesis, we determined that GRP signaling is essential for the continued survival and development of newborn neurons, both of which are blocked by transient knockdown of GRP's cognate receptor (GRPR). Furthermore, GRP appears to negatively regulate neurogenesis-associated proliferation in neural stem cells both in vitro and in vivo. Intracerebroventricular infusion of GRP resulted in a decrease in immature neuronal markers, increased cAMP response element-binding protein (CREB) phosphorylation, and decreased neurogenesis. Despite increased levels of GRP mRNA, CaMK2α-hKO mutant mice expressed reduced levels of GRP peptide. This lack of GRP may contribute to the elevated neurogenesis and impaired neuronal development, which are reversed following exogenous GRP infusion. Based on these findings, we hypothesize that GRP modulates neurogenesis and neuronal development and may contribute to hippocampus-associated cognitive impairment.
