Hyperuricemic nephropathy is a metabolic disease in which renal uric acid deposition and excretion are impaired due to elevated levels of uric acid in the blood, leading to impaired renal tubule function and chronic renal disease. Hyperuricemic nephropathy is one of the important complications of hyperuricemia, which seriously affects the quality of life and prognosis of patients. ⋯ In recent years, omics techniques such as metabolomics, transcriptomics and intestinal microecology have been used to reveal the metabolic, gene and microflora characteristics of hyperuricemic nephropathy from different levels, as well as their interactions and regulatory mechanisms. This paper reviews these studies, analyzes the existing problems and challenges, and puts forward future research directions and suggestions, aiming at providing new theoretical basis and practical guidance for the prevention and treatment of hyperuricemic nephropathy.

Comparative Study Observational Study
Incidence of acute angle closure in patients with primary angle closure without prophylactic iridotomy during pharmacological mydriasis for cataract surgery.
The objective was to study the incidence of acute primary angle closure (acute PAC) during pharmacologic mydriasis before cataract surgery and changes in anterior chamber angle parameters in patients with primary angle closure diseases (PACD) with and without prophylaxis laser peripheral iridotomy (LPI). This was a prospective, comparative study of cataract patients with PACD with and without prophylaxis LPI presented at the Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand during June 2022 to December 2023. The incidence of acute PAC during pharmacologic mydriasis prior to cataract surgery was recorded. ⋯ There was no incidence of acute PAC in patients with and without prophylaxis LPI during pharmacological mydriasis in the preoperative preparation for cataract surgery. Eyes without LPI showed significantly lower preoperative anterior chamber angle parameters compared to eyes with previous LPI, but not significantly different postoperatively. The benefits of prophylactic LPI for PACD scheduled for cataract surgery must be further investigated.

Analysis of lung microbiota in pediatric pneumonia patients using BALF metagenomic next-generation sequencing: A retrospective observational study.
The contribution of the lung microbiota to pneumonia in children of varying severity remains poorly understood. This study utilized metagenomic next-generation sequencing (mNGS) technology to elucidate the characteristics of lung microbiota and their association with disease severity. This retrospective study analyzed bronchoalveolar lavage fluid (BALF) mNGS data of 92 children diagnosed with pneumonia between January 2021 and July 2022. ⋯ Spearman analysis indicated a highly significant positive correlation between the abundance of Prevotella melaninogenica and M pneumoniae (P < .001). Our analysis identified an association between M pneumoniae infections and disease severity. This study provides a foundation for a better understanding of the pathogenesis of pediatric pneumonia and the relationship between microorganisms.

Comparative Study Observational Study
Total gastrectomy patients had a lower diet volume and greater diet frequency than distal gastrectomy patients after 6 months.
There are no reports comparing diet recovery between patients who underwent distal gastrectomy (DG) and those who underwent total gastrectomy (TG). The aim of the present study was to compare dietary habits and nutritional status after curative treatment with DG and TG in patients with gastric cancer. We retrospectively collected clinical data from 263 consecutive patients who underwent gastrectomy for gastric cancer without recurrence at a single-center between January 2016 and December 2022. ⋯ Patients who underwent TG had a lower diet volume and a greater diet frequency than DG patients did after 6 months. Postoperative nutrition education should be tailored differently for patients undergoing DG and TG. Specifically, TG patients should be educated to increase diet frequency rather than diet volume after surgery.

Immune reconstitution is a significant factor in the success of "hematopoietic stem cell transplantation" (HSCT). Delaying the immune reconstitution increases the risk of infections and relapse after transplantation. T-cell recovery after HSCT is mainly thymus-dependent, and thymic atrophy is associated with various clinical conditions that correlate with HSCT outcomes. Thymus rejuvenation can improve immune reconstitution after transplantation.Zinc (Zn) plays a pivotal role in thymus rejuvenation. Zn deficiency can lead to thymic atrophy, which increases susceptibility to infections. Zn supplementation restores the immune system by increasing thymus output and T-cell repertoire production.We designed this protocol to investigate the effect of oral Zn supplementation on T-cell recovery in patients undergoing HSCT. ⋯ This clinical trial is the first to determine the efficiency of "Zn gluconate" as daily Supplementation in T cell recovery post-HSCT.If successful, an available and inexpensive drug will improve immune system reconstruction after HSCT, reduce the risk of infection, particularly viral infections, and increase patient survival.
