Background: Pulmonary embolism (PE) is a potentially life-threatening condition. Admission and treatment in the intensive care unit (ICU) is an important element in critically ill PE patients.
Objectives: We aimed to identify risk factors for ICU admission and differences in patient profiles regarding risk factors and comorbidities between PE patients who had to be admitted to an ICU and those who were treated in a normal ward without ICU.
Methods: We used the German nationwide inpatient sample to analyze all hospitalizations of PE patients in Germany from 2016 to 2020 stratified for ICU admission.
Results: Overall, 484,859 hospitalized PE patients were treated in German hospitals from 2016 to 2020. Among these, 92,313 (19.0%) were admitted to ICU. Patients treated in ICU were younger (69.0 [IQR, 58.0-78.0] vs 72.0 [IQR, 60.0-80.0] years; < .001) and had higher prevalence of cardiovascular risk factors and comorbidities. In-hospital case fatality rate was elevated in PE patients treated in ICU (22.7% vs 10.7%; < .001), and ICU admission was independently associated with increased in-hospital case fatality (odds ratio [OR], 2.54; 95% CI, 2.49-2.59; < .001). Independent risk factors for ICU admission comprised PE with imminent or present decompensation (OR, 3.30; 95% CI, 3.25-3.35; < .001), hemodynamic instability (OR, 4.49; 95% CI, 4.39-4.59; < .001), arterial hypertension (OR, 1.20; 95% CI, 1.18-1.22; < .001), diabetes mellitus (OR, 1.16; 95% CI, 1.14-1.18; < .001), obesity (OR, 1.300; 95% CI, 1.27-1.33; < .001), surgery (OR, 2.55; 95% CI, 2.50-2.59; < .001), stroke (OR, 2.86; 95% CI, 2.76-2.96; < .001), pregnancy (OR, 1.45; 95% CI, 1.21-1.74; < .001), heart failure (OR, 1.74; 95% CI, 1.71-1.77; < .001), atrial fibrillation/flutter (OR, 1.69; 95% CI, 1.66-1.73; < .001), chronic obstructive pulmonary disease (OR, 1.21; 95% CI, 1.18-1.24; < .001), and renal failure (OR, 1.92; 95% CI, 1.88-1.95; < .001).
Conclusion: ICU treatment is an important element in the treatment of PE patients. Besides hemodynamic compromise, cardiovascular risk factors, stroke, pregnancy, and cardiopulmonary as well as renal comorbidities were independent predictors of ICU admission. Necessity of ICU admission was afflicted by increased case fatality.

Objective: Preventing return to alcohol is of critical importance for patients with alcohol-related cirrhosis and/or alcohol-associated hepatitis. Acamprosate is a widely used treatment for alcohol use disorder (AUD). We assessed the impact of acamprosate prescription in patients with advanced liver disease on abstinence rates and clinical outcomes.

: To assess the ploidy status of embryos via preimplantation genetic testing for aneuploidy (PGT-A), a biopsy of trophectoderm (TE) cells can be performed. However, this approach is considered invasive, and therefore the aim of this study was to identify the optimal sample type and sampling day for non-invasive or minimally invasive PGT-A (ni/miPGT-A) in terms of data quality and concordance rates with TE biopsies derived from the same embryos. : This study was performed using 239 embryo cultures.

: Falls are a major public health concern. Daily vitamin D supplementation is a proposed fall prevention strategy; however, safety concerns have arisen from some clinical trials showing increased fall risk when using higher vitamin D dosing methods. The relationship between vitamin D and falls may be influenced by factors, such as inflammation, which can alter the balance of essential nutrients like vitamin D and retinol, potentially affecting motor function.

Cisplatin is a common and highly effective chemotherapeutic agent whose nephrotoxic side effect is well-characterized. Sodium thiosulfate (STS), an FDA-approved hydrogen sulfide (HS) donor drug, is emerging as a chemoprotective agent against cisplatin-induced nephrotoxicity (CIN). In this study, we investigated the chemoprotective mechanism of STS in a rat model of CIN.
