Purpose Despite the need for advanced hemodynamic monitoring, the role of the pulmonary artery catheter (PAC) in cardiogenic shock (CS) remains controversial due to conflicting evidence from previous studies. Material and Methods This single-center retrospective study utilized the MIMIC-IV database to assess the impact of PAC use on 30-day in-hospital mortality and clinical outcomes in CS patients admitted between 2008 and 2019. Propensity score matching (PS) and inverse propensity treatment weighting (IPTW) were employed to adjust for baseline differences. The primary outcome was 30-day in-hospital mortality; secondary outcomes included hospital and ICU length of stay and complications. Cox proportional hazard ratio analyses were performed to evaluate the association between PAC use and mortality outcomes. Results The final cohort consisted of 1940 adult CS patients, with 134 receiving PAC and 1806 not. PAC use significantly reduced 30-day in-hospital mortality (PS-matched HR 0.57, 95% CI: 0.39-0.83; IPTW HR 0.58, 95% CI: 0.35-0.96) but was associated with longer hospital stays (16.47 vs 12.37 days) and ICU stays (9.26 vs 7.52 days). Conclusion PAC use in CS patients was associated with improved short-term survival but also with longer hospitalization and potential complications, underscoring the need for careful patient selection and further research.

Background Safety-net hospitals (SNH) provide care to a significant proportion of low-income, uninsured, and underserved populations disproportionately affected by the COVID-19 pandemic. We evaluated the impact of safety-net burden on outcomes of COVID-19 hospitalizations. Methods We identified patients aged ≥ 18 years hospitalized with COVID-19 from the nationwide inpatient database using the International Classification of Diseases, Tenth Edition (ICD-10-CM) code U07.1. The primary study outcomes were inpatient mortality, respiratory failure requiring mechanical ventilation, and tracheostomy use. Secondary outcomes were total hospitalization costs (THC) and length of hospital stay (LOS). Multivariable logistic regression was used to compare the primary and secondary outcomes in HBH and medium safety-net burden (MBH) with lower-burden hospitals (LBH) (reference). Results An estimated 2,608,232 COVID-19 hospitalizations met the inclusion criteria, with 68.7% occurring in HBH, 22.8% in MBH, and 8.5% in LBH. On adjusted multivariable analysis, HBH was associated with increased odds of inpatient mortality (aOR 1.19, 95% CI 1.09-1.28) compared with LBH. Both HBH (aOR 1.30, 95% CI 1.21-1.40) and MBH (aOR 1.14, 95% CI 1.06-1.24) demonstrated increased odds of mechanical ventilation compared with LBH. THC was lower in HBH and MBH compared with LBH. The LOS was similar across safety net burden categories. Conclusion After adjusting for patient- and hospital-level factors, COVID-19 hospitalizations at HBH had inferior inpatient outcomes compared with LBH. Targeted policy reforms are needed to address the underlying causes of these disparities and increase our health systems’ readiness for future crises, particularly in underserved communities.

While hormonal changes have been recognised to influence seizure control and have been studied in association with menstrual cycles and pregnancy, there is a paucity of data on the menopause transition in epilepsy. Given the known effects of sex steroid hormones on neuronal excitability, their endogenous fluctuations during perimenopause, as well as menopause hormone treatments, may alter seizure control. Epilepsy may also be associated with premature ovarian insufficiency and early menopause. This is especially important for epilepsy-related comorbidities, for which menopause can constitute a second hit, such as osteoporosis. Additional considerations for females with epilepsy across the menopause continuum include changes in antiseizure medication clearance and potential interactions with menopausal hormone therapy or other concomitant medications. This comprehensive review summarises the currently available literature on epilepsy and menopause, highlights gaps in knowledge, and underscores the need for research efforts, particularly longitudinal studies investigating the menopause transition.

Abstract Superior mesenteric artery (SMA) thrombosis is rare yet critical illness that can result in lethal bowel ischemia and infarction. This report details a case of SMA thrombosis with associated superior mesenteric vein (SMV) narrowing, secondary to mesenteric torsion in a 26-year-old female with history of Roux-en-Y gastric bypass surgery. The patient’s presenting symptoms were severe epigastric pain, vomiting, and significant anemia. Imaging confirmed SMA thrombosis with early signs of bowel ischemia. Interventional radiology promptly performed an SMA angiogram and initiated thrombolysis with a tenecteplase infusion, which led to near-complete resolution of the thrombus. This case draws attention to the necessity for early diagnosis and swift management of SMA thrombosis, particularly in post-surgical patients with altered gastrointestinal anatomy. The resolution of this case demonstrates the value of a collaborative care, combining interventional radiology and general surgery to prevent bowel ischemia.

Heart transplantation is a well-established treatment for end-stage heart failure, but many patients present in poor physical condition, complicating outcomes. The Impella 5.5 device, used in cardiogenic shock, may support pretransplant rehabilitation by stabilizing organ function and promoting functional improvement. This retrospective cohort study assessed the relationship between functional status, measured by standardized Activity Measure for Post-Acute Care Basic Mobility (AM-PAC) scores, and days alive outside the hospital within 30 days post-transplant (DAOH-30). Patients who received Impella 5.5 support before transplantation between January 2019 and October 2023 were included, excluding those without AM-PAC scores within 24 hours pretransplant. Among 65 patients, the median DAOH-30 was 15 days (interquartile range [IQR], 8–19). Higher pretransplant standardized AM-PAC scores correlate with increased DAOH-30 (adjusted coefficient 0.3; 95% confidence interval [CI] = 0.01–0.6; p = 0.04), as did AM-PAC score improvement during rehabilitation (adjusted coefficient 0.35; 95% CI = 0.01–0.6; p = 0.04). Extended rehabilitation was associated with greater functional gains. These findings suggest that better pretransplant functional status and rehabilitation-related improvements were associated with increased DAOH-30. The Impella 5.5 device facilitates rehabilitation and may enhance post-transplant outcomes. Further research should refine strategies to optimize rehabilitation and recovery in this high-risk population.

Background: Procalcitonin (PCT) is recognized as an inflammatory biomarker, often elevated in COVID-19 pneumonia alongside other biomarkers. Understanding its association with severe outcomes and comparing its predictive ability with other biomarkers is crucial for clinical management. Objectives: This retrospective multicenter observational study aimed to investigate the association between PCT levels and adverse outcomes in hospitalized COVID-19 patients. Additionally, it sought to compare the predictive performance of various biomarkers. Design: The study analyzed data from the Society of Critical Care Medicine (SCCM) Viral Infection and Respiratory Illness Universal Study (VIRUS) registry, comprising COVID-19 patients hospitalized across multiple Mayo Clinic sites between March 2020 and June 2022. Methods: A total of 7851 adult COVID-19 patients were included. Patients were categorized into 6 groups based on the worst WHO ordinal scale. Multivariate models were constructed using peak biomarker levels within 72 hours of admission, adjusted for confounders. Results: Elevated PCT levels were independently associated with increased odds of adverse outcomes, including ICU admission (adjusted odds ratio [aOR] 1.32, 95%CI 1.27-1.38), IMV requirement (aOR 1.35, 95%CI: 1.28-1.42), and in-hospital mortality (aOR 1.30, 95%CI: 1.22-1.37). A 3.48-fold increase in IMV requirement and 3.55 times increase in in-hospital mortality were noted with peak PCT ⩾ 0.25 ng/ml. Similar associations were observed with other biomarkers like NLR (AUC 0.730), CRP, IL-6, LDH (AUC 0.800), and D-dimer (AUC 0.719). Models incorporating NLR, LDH, D-dimer, and PCT demonstrated the highest predictive accuracy, with a combined model exhibiting an area under the curve (AUC) of 0.826 (95%CI 0.803-0.849). Conclusions: Higher PCT levels were significantly linked to worse outcomes in COVID-19 patients, emphasizing its potential as a prognostic marker. Biomarker-based predictive models, particularly those including PCT, showed promising utility for risk assessment and clinical decision-making. Further prospective studies are warranted to validate these findings on a larger scale.

A 46-year-old man, an immigrant from Central America, presented to the emergency department after a motor vehicle collision. He had developed a progressive headache over the previous 48 hours, which had suddenly worsened while driving, causing him to crash. There was no significant head trauma. Clinical and radiological findings prompted a workup for atypical subarachnoid haemorrhage.
