Objectives: To identify the structural and patient characteristics associated with better care processes in older vulnerable hospitalized patients.
Design: Retrospective study.
Setting: Forty-four Geriatric Assessment Units (GAU).
Participants: Patients aged 65 and older who were admitted to a GAU for a fall with trauma.
Measurements: Three care processes (comprehensiveness, informational continuity, completion of advance health care directives) assessed through chart audit; 14 patient- and 23 GAU-related characteristics obtained from hospitalization records, national databases, and GAU managers.
Results: A total of 877 hospitalization records were included. Final models were based on multilevel modeling using stepwise variable selection. Strongest predictors of better comprehensiveness were longer hospital length of stay (LOS), higher clinical complexity (eg, higher mortality risk), and having a geriatrician as attending physician. Comprehensiveness score increased sharply up to 3 weeks LOS and then tended to plateau. Better informational continuity was associated with more comprehensive care, higher risk of mortality, acute rather than rehabilitation care, communication with community health care professionals within 48 hours after admission, and a target LOS of 3 weeks or longer. The completion of advance directives was more likely in the presence of advanced age, higher risk of mortality, cognitive impairment, discharge to another care facility, longer LOS, university-affiliated institution, and nonurban location.
Conclusion: In GAUs, quality-of-care processes are related to both structural and patient characteristics. Our results pointed toward an organizational framework that may help to streamline the geriatric units and better use resources, notably by narrowing the admission criteria, targeting a proper LOS, improving communication with community organizations, and making systematic completion of advance directives.

Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) of the colon is rare with a poor prognosis. Since the first description of a mixed neoplasm 100 years ago, the nomenclature has evolved, most recently with the 2022 World Health Organization (WHO) classification system. We describe our experience of a case of locoregionally advanced MiNEN of the descending colon treated with curative laparoscopic resection and adjuvant chemotherapy.

The negative symptoms of schizophrenia include diminished emotional expression, avolition, alogia, anhedonia, and asociality, and due to their low responsiveness to available treatments, are a primary driver of functional disability in schizophrenia. This narrative review has the aim of providing a comprehensive overview of the current research developments in the treatment of negative symptoms in schizophrenia, and begins by introducing the concepts of primary, secondary, prominent, predominant, and broadly defined negative symptoms. We then compare and contrast commonly used research assessment scales for negative symptoms and review the evidence for the specific utility of widely available off-label and investigational treatments that have been studied for negative symptoms.

Molecule interacting with CasL-2 enhances tumor progression and alters radiosensitivity in cervical cancer.

Objective: Cervical cancer is a common malignancy among women, and radiotherapy remains a primary treatment modality across all disease stages. However, resistance to radiotherapy frequently results in treatment failure, highlighting the need to identify novel therapeutic targets to improve clinical outcomes.
Methods: The expression of molecule interacting with CasL-2 (MICAL2) was confirmed in cervical cancer tissues and cell lines through western blotting (WB) and immunohistochemistry (IHC).
Semi-closed-circuit vacuum-assisted mini percutaneous cystolithotomy (vamPCL) in the pediatric population: Initial experience of a novel technique in native and augmented bladders.

Introduction: Bladder stones (BS) in children are a rare condition and represent 1-5 % of all urinary tract stones. With advances in miniaturized endoscopes and intracorporeal lithotripters, percutaneous cystolithotomy has been demonstrated to be an effective, safe and quick technique, despite the longer operative time. This limitation may be overcome by a semi-closed-circuit vacuum-assisted technology (vamPCL), characterized by a continuous inflow and a suction-controlled outflow (ClearPetra®).
