Background: Shanghai's high level of ageing has given rise to a considerable number of elderly patients with type 2 diabetes mellitus (T2DM) who are confronted with the challenge of managing multimorbidity. We aimed to determine the prevalence of multimorbidity in elderly T2DM patients in a representative Pudong New Area community and critically evaluate current guidelines' inclusiveness in addressing major comorbidities.
Methods: Through the Shanghai Health Cloud platform, we extracted medical records of residents in the Huamu community (Pudong New Area, Shanghai) to screen elderly patients with at least three outpatient visits or one hospitalisation per year between 2019 and 2022.
Objectives: This study aimed to investigate the nephroprotective effect of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in elderly patients with type 2 diabetes mellitus (T2DM) and hypertension based on real-world clinical data. The study aimed to provide a theoretical basis for evidence-based pharmacological treatment of chronic kidney disease in this population.
Methods: The 'Health Cloud' platform of the Shanghai Municipal Health Commission was employed to identify and screen elderly patients with T2DM and hypertension.
Background: Elderly patients with multimorbidity are at higher risk of greater healthcare costs and poor outcomes due to decreased physical function. The aim of this study was to investigate the impact of infection on healthcare costs and poor outcomes in elderly hospitalized patients with multimorbidity.
Methods: We retrospectively enrolled 264 patients who met the inclusion criteria from the department of geriatrics of a large public hospital in Shanghai, China between January 2020 and December 2020.
Background: Mesenchymal stem cells (MSCs) hold a great promise for cell-based therapy in the field of regenerative medicine. In this study, we aimed to evaluate the safety and efficacy of intravenous infusion of human umbilical cord-derived MSCs (HUC-MSCs) in patients with aging frailty.
Methods: In this randomized, double-blind, placebo-controlled trial, participants diagnosed with aging frailty were randomly assigned to receive intravenous administrations of HUC-MSCs or placebo.

Organosilane compounds are widely used in both organic synthesis and materials science. Particularly, 1,2-disilylated and -disilylated alkenes, characterized by a carbon-carbon double bond and multiple silyl groups, exhibit significant potential for subsequently diverse transformations. The versatility of these compounds renders them highly promising for applications in materials, enabling them to be valuable and versatile building blocks in organic synthesis.

Background: There is a high incidence rate of age-related hearing loss. Severe hearing loss may increase the prevalence of mental illness, cognitive impairment, and even the risk of all-cause death.
Purpose: Construction of the three-level and two-stage screening mode for age-related hearing loss of the community and to evaluate its effectiveness.
Objective: Hospital-associated venous thromboembolism (VTE) is a major cause of unintended death in hospitalized patients. Standardized and reasonable prevention measures may reduce its occurrence effectively. This study aims to analyze the consistency of VTE risk assessment by physicians and nurses and its potential causes.

The development of aryl alkyl sulfides as dichotomous electrophiles for site-selective silylation via C-S bond cleavage has been achieved. Iron-catalyzed selective cleavage of C(aryl)-S bonds can occur in the presence of β-diketimine ligands, and the cleavage of C(alkyl)-S bonds can be achieved by t-BuONa without the use of transition metals, resulting in the corresponding silylated products in moderate to excellent yields. Mechanistic studies suggest that Fe-Si species may undergo metathesis reactions during the cleavage of C(aryl)-S bonds, while silyl radicals are involved during the cleavage of C(alkyl)-S bonds.

Organoboron and organosilane compounds are widely used in organic synthesis and pharmaceuticals. In addition, the C-F bond functionalization is a useful tool for the construction of carbon-carbon and carbon-heteroatom bonds. In particular, the late-stage functionalization of bioactive molecules through defluoroborylation and defluorosilylation reactions will provide good opportunities for the development and diversification of new medicinal compounds.

This protocol features good functional group compatibility and excellent regio- and stereoselectivity, enabling the late-stage silylation of biologically relevant compounds, thus providing good opportunities for applications in medicinal chemistry. Preliminary mechanistic studies and DFT calculations reveal that a nucleophilic addition and elimination of the second C-F bond might be involved in the disilylation catalytic system, demonstrating unusual reactivity characteristics of iron catalysis.
