Background: Frailty is a predictor of adverse outcomes in older subjects.
Aims: The aims of this study are to (1) measure the frailty status and its changes occurring during the hospital stay, (2) determine the relationships among frailty and adverse outcomes.
Methods: Frailty was assessed using a 46-item Frailty Index (FI) in 156 patients admitted to an Acute Geriatric Medicine Unit. The FI was calculated within 24 h from the hospital admission (aFI) and at his/her discharge (dFI). Patients were followed up to 12 months after the hospital discharge.
Results: A statistically significant difference was reported between the aFI (0.31, IQR 0.19-0.44) and the dFI (0.29, IQR 0.19-0.40; p = 0.04). The aFI was directly associated with the risk of in-hospital death (OR = 5.9; 95% CI 2.0-17.5; p = 0.001), 1 year mortality (OR = 5.5, 95% CI 2.4-12.7, p < 0.001) and re-hospitalization (OR = 6.3, 95% CI 2.2-17.9, p = 0.03).
Conclusion: Frailty is a strong predictor of negative endpoints in hospitalized older persons.
Discussion: Frailty assessment from routinely collected clinical data may provide important insights about the biological status of the individual and promote the personalization of care.

BACKGROUND This study aimed to analyze the risk factors of central nervous system (CNS) infection caused by reactivation of varicella zoster virus (VZV) and provide reference for the prevention and early diagnosis of VZV-associated CNS infection. MATERIAL AND METHODS A prospective study was conducted on 1030 patients with acute herpes zoster (HZ) admitted to our hospital from January 2021 to June 2023. According to clinical manifestations and auxiliary examinations, they were divided into HZ group of 990 patients and VZV-associated CNS infection group of 40 patients.

With the advancement of precise hepatobiliary surgery concepts, the diagnostic and therapeutic approaches for hepatic echinococcosis have undergone significant transformations. However, whether these changes have correspondingly improved patient outcomes remains unclear. A retrospective analysis of these changes will provide crucial guidance for the prevention and treatment of hepatic echinococcosis.

The aim was to identify predictors for early identification of HFNC failure risk in patients with severe community-acquired (CAP) pneumonia or COVID-19. Data from adult critically ill patients admitted with CAP or COVID-19 and the need for ventilatory support were retrospectively analysed. HFNC failure was defined as the need for invasive ventilation or death before intubation.

Neuron-derived neurotrophic factor (NDNF) was discovered as a target antigen in membranous nephropathy (MN) caused by syphilis. However, there have been few reports of NDNF-positive MN in Japan. A 19-year-old female patient was admitted to our hospital with nephrotic syndrome and acute kidney injury.

The aim of this study was to evaluate how COVID-19 affected acute stroke care and outcome in patients with acute ischemic or hemorrhagic stroke. We performed a retrospective analysis on patients who were admitted with acute ischemic (AIS) or hemorrhagic (ICH) stroke from September 2020 to May 2021 with and without COVID-19. We recorded demographic and clinical data, imaging parameters, functional outcome and mortality at one year.
