Heart failure (HF) with improved ejection fraction (HFimpEF) has gradually attracted widespread attention in recent years for its better clinical prognosis. In this study, we attempted to investigate the relationship between subclinical hypothyroidism (SCH) and HFimpEF. This study retrospectively collected clinical data on patients with HF with reduced ejection fraction (HFrEF) hospitalized at the First Affiliated Hospital of USTC from March 2015 to September 2023, and divided into two groups as euthyroidism or SCH according to the baseline thyroid function. ⋯ Univariate logistic regression analysis indicates that SCH was a potential predictor for HFimpEF (OR: 0.612 [95% CI 0.403-0.928], P = 0.021). After adjusting for multiple factors in logistic regression, the odds ratios of HFrEF patients with SCH progressing to HFimpEF decreased by 37.8% (OR: 0.622 [95% CI 0.397-0.974], P = 0.038) compared with patients with euthyroidism. This study suggests that thyroid function affects the improvement of cardiac function in patients with HFrEF and SCH is an independent predictor for HFimpEF.

Diaphragmatic ultrasound: approach, emerging evidence, and future perspectives in non-ICU patients.
Diaphragmatic dysfunction is an important contributor to hypercapnic respiratory failure, but its presence is often challenging to determine at the bedside. Diaphragm ultrasound provides an opportunity to evaluate the function of the diaphragm noninvasively by evaluating the following parameters that can help define diaphragmatic dysfunction: diaphragm excursion, diaphragm muscle thickness, and thickening fraction. ⋯ This article provides an overview on how to perform diaphragm ultrasound, review its pitfalls, and discuss the evidence of its use in patients with neuromuscular disorders and chronic obstructive pulmonary disease. Finally, its potential emerging uses in the perioperative setting and for evaluation of acute heart failure are discussed.

Adhering to bundle-based care recommendations within stringent time constraints presents a profound challenge. Elements within these bundles hold varying degrees of significance. We aimed to evaluate the Surviving Sepsis Campaign (SSC) hour-one bundle compliance patterns and their association with patient outcomes. ⋯ Adjusting for covariates, C#1 and C#3 were associated with reduced odds of in-hospital mortality compared to C#0 (adjusted odds ratio [aOR] = 0·83; 95% confidence interval [CI] 0·7-0·97 and aOR = 0·7; 95% CI 0·53-0·91, respectively). C#1 exhibited significantly better 1-year survival (adjusted hazard ratio [aHR] = 0·9; 95%CI 0·81-0·99). We were able to identify distinct clusters of SSC hour-one bundle adherence patterns using unsupervised machine learning techniques, which were associated with patient outcomes.

Some studies have explored the relationship between metabolic abnormalities, elevated liver enzymes and gallstone risk, but the results have been inconsistent. The aim of this study was to comprehensively assess the relationship between metabolic abnormalities, liver enzymes, and gallstone risk through a cross-sectional study and Mendelian randomization analysis. ⋯ The findings suggest that metabolic abnormalities and elevated liver enzymes may increase the risk of developing gallstones.
