In-hospital stress and patient outcomes: A systematic review and meta-analysis.

BACKGROUND: Hospital inpatients are exposed to high levels of stress during hospitalisation that may increase susceptibility to major adverse health events post-hospitalisation (known as post-hospital syndrome). However, the existing evidence base has not been reviewed and the magnitude of this relationship remains unknown. Therefore, the aim of the current systematic review and meta-analysis was to: 1) synthesise existing evidence and to determine the strength of the relationship between in-hospital stress and patient outcomes, and 2) determine if this relationship differs between (i) in-hospital vs post-hospital outcomes, and (ii) subjective vs objective outcome measures. METHODS: A systematic search of MEDLINE, EMBASE, PsychINFO, CINAHL, and Web of Science from inception to February 2023 was conducted. Included studies reported a measure of perceived and appraised stress while in hospital, and at least one patient outcome. A random-effects model was generated to pool correlations (Pearson's r), followed by sub-group and sensitivity analyses. The study protocol was preregistered on PROSPERO (CRD42021237017). RESULTS: A total of 10 studies, comprising 16 effects and 1,832 patients, satisfied the eligibility criteria and were included. A small-to-medium association was found: as in-hospital stress increased, patient outcomes deteriorated (r = 0.19; 95% CI: 0.12-0.26; I2 = 63.6; p < 0.001). This association was significantly stronger for (i) in-hospital versus post-hospital outcomes, and (ii) subjective versus objective outcome measures. Sensitivity analyses indicated that our findings were robust. CONCLUSIONS: Higher levels of psychological stress experienced by hospital inpatients are associated with poorer patient outcomes. However, more high-quality, larger scale studies are required to better understand the association between in-hospital stressors and adverse outcomes.

Safety and efficacy of colesevelam HCl in the treatment of elderly patients.

BACKGROUND AND OBJECTIVES: Colesevelam significantly lowers cholesterol in patients with hypercholesterolemia, and both cholesterol and hemoglobin A1C (A1C) in patients with type 2 diabetes mellitus (T2DM). The purpose of this post hoc analysis was to evaluate the efficacy and safety/tolerability of colesevelam in older (≥65 years) and younger (<65 years) adults. METHODS: We conducted post hoc analyses of pooled clinical trial data from seven phase II and III randomized, double-blind, placebo-controlled, primary hyperlipidemia and T2DM clinical trials. The hyperlipidemia safety/tolerability analysis included seven studies (≥65 years, n = 154; <65 years, n = 381); the efficacy analysis utilized one study with sufficient patients in both age groups for meaningful comparison. The T2DM analyses included four studies (safety/tolerability: ≥65 years, n = 249; <65 years, n = 880) or three studies (efficacy). In the hyperlipidemia studies, patients received colesevelam 1.5-4.5 g/day or placebo, alone or with a statin, for 4 weeks to 6 months. In the T2DM studies, colesevelam 3.75 g/day or placebo was added to existing antidiabetes therapies for 16 or 26 weeks. Low-density lipoprotein cholesterol (LDL-C), A1C, and adverse events were assessed. RESULTS: In the hyperlipidemia analysis, colesevelam versus placebo produced similar mean reductions from baseline in LDL-C in older (-16.6 vs. +0.5 %) and younger (-13.7 vs. +0.4 %) patients. In the T2DM analysis, older and younger patients had similar reductions from baseline in A1C (treatment difference -0.59 and -0.54 %, respectively; both p < 0.001) and LDL-C (-14.7 and -15.5 %, respectively; both p < 0.001) with colesevelam. In both analyses, adverse event incidence was generally similar between subgroups. In the T2DM analysis, hypoglycemia was slightly more frequent with colesevelam versus placebo in older patients (5.8 vs. 2.3 %); no reports of hypoglycemia were considered serious adverse events. CONCLUSIONS: In primary hyperlipidemia and in T2DM, colesevelam appeared to be generally as safe, well tolerated, and efficacious in patients aged ≥65 years as in those aged <65 years.

Pharmacological effects of CS-0777, a selective sphingosine 1-phosphate receptor-1 modulator: results from a 12-week, open-label pilot study in multiple sclerosis patients.

CS-0777 is a selective sphingosine 1-phosphate receptor-1 modulator under investigation for treatment of multiple sclerosis (MS). We conducted an open-label, pilot study in 25 MS patients to assess the safety, pharmacokinetics, pharmacodynamics and exploratory efficacy of oral CS-0777 (0.1, 0.3 and 0.6 mg), administered once weekly or every other week for 12 weeks. CS-0777 resulted in a pronounced, dose-dependent decrease in lymphocytes and CD4 T cell subsets, which returned to baseline within 4 weeks after the last dose. Overall, CS-0777 was safe and well-tolerated. These results require confirmation in a double-blind, placebo-controlled and adequately powered phase 2 study in MS.
