Congestive heart failure is prevalent in the elderly; recurrent hospital admissions for acute deterioration is a major health care problem. We examined tumor necrosis factor alpha levels in 31 congestive heart failure patients who were admitted to the hospital due to acute cardiogenic pulmonary edema. Blood samples were taken within 24 hours of admission and at the time of discharge after recovery. Tumor necrosis factor alpha levels were also measured in 10 stable congestive heart failure outpatients and 16 healthy controls. Tumor necrosis factor alpha level at admission was higher than at time of discharge (4.6Â+/-1.9 vs. 3.4Â+/-1.1 (rg/mL, p is less than 0.02). Mean tumor necrosis factor alpha level of stable congestive heart failure outpatient was 2.6Â+/-0.7 rg/mL healthy controls had significantly lower tumor necrosis factor alpha levels (1.7Â+/-0.7 rg/mL) than congestive heart failure patients (p is less than 0.01). tumor necrosis factor alpha levels were highest among acute congestive heart failure patients. Elevated tumor necrosis factor alpha appears to be related to the exacerbation of congestive heart failure and may be a marker for deterioration. (c) 2000 by CVRR, Inc.

Incidence and Risk Factors for Varicella-Zoster Virus-Associated Central Nervous System Infections: A Nationwide Swedish Retrospective Case-Control Study.
J Med Virol

Department of Infectious Diseases, Institute of Biomedicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.
The determinants of varicella-zoster virus (VZV)-associated central nervous system (CNS) infection have not been fully elucidated. This study aimed to investigate the incidence and risk factors, including immunosuppression, for different manifestations of VZV-associated CNS infection. Patient registers were used to include adults diagnosed with VZV-associated CNS infections between 2010 and 2019 in Sweden.

Background: Valve-in-valve transcatheter aortic valve replacement (ViV-TAVR) is associated with improved perioperative safety compared to redo surgical aortic valve replacement (redo-SAVR), but long-term outcomes remain uncertain. We therefore compare long-term outcomes of ViV-TAVR and redo-SAVR.
Methods: The study included 1:1 propensity-matched Medicare beneficiaries with degenerated bioprosthetic valves admitted between 09/29/2011 and 12/30/2020 undergoing either redo-SAVR or ViV-TAVR.
Differences between private and public primary health care centers and differences between men and women in antihypertensive care and cardiovascular prevention in all patients with hypertension treated in primary care in Stockholm County, Sweden.
BMC Prim Care
January 2025
Division of Family Medicine and Primary Care, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Huddinge, Sweden.
Aims: To study differences in cardiovascular prevention and hypertension management in primary care in men and women, with comparisons between public and privately operated primary health care (PHC).
Methods: We used register data from Region Stockholm on collected prescribed medication and registered diagnoses, to identify patients aged 30 years and above with hypertension. Age-adjusted logistic regression was used to calculate odds ratios (ORs) with 99% confidence intervals (99% CIs) using public PHC centers as referents.

Left atrial (LA) hypertension is central in the pathophysiology of heart failure (HF) in general and of HF with preserved ejection fraction (HFpEF) in particular. Despite approved treatments, a number of HF patients continue experiencing disabling symptoms due to LA hypertension, causing pulmonary congestion, pulmonary hypertension, and right heart dysfunction, at rest and/or during exercise. LA decompression therapies, i.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).
