Background: Fluid removal remains a fundamental goal in the treatment of congestive heart failure (CHF). Vacuum ultrafiltration, hemodialysis, or a combination of both was used in patients with severe CHF (NYHA class IV), severe edema, and insensitivity to pharmacological treatment with diuretics.
Methods: The aim of the study was to remove the overload fluid in eighteen patients, 13 men and 5 women, aged 38 to 83, with a man age of 66 years with intractable congestive heart failure. All patients were hospitalized because of severe congestive heart failure and did not respond to treatment with intravenous administration of a high dose of diuretics and positive inotropic agents. They thus underwent vacuum ultrafiltration (1 to 27 sessions) while in 4 of them hemodialysis was also performed because of high serum creatinine levels (over 4 mg/dl). Subclavian catheters were used in all patients and arteriovenous fistula was later performed in 2, because of the need for long term treatment. The average fluid removed was 2 L per session and the total fluid removed ranged from 4 to 29 L.
Results: Fourteen of the 18 patients (78%) showed significant improvement in their clinical status. Ten patients (56%) had a short term improvement but expired after 7 to 107 days of hospitalization. Four patients (22%) died after only one session of dialysis and 4 patients (22%) recovered after 8 to 23 dialysis sessions and were discharged from hospital.
Conclusion: The majority of patients with severe chronic CHF which is intractable to conventional therapy including intravenous diuretics and inotropes improve by the use of ultrafiltration. However, a limited proportion of them survive to be discharged from the hospital.

Racial Disparities in Cardiometabolic Disorders Among Alzheimer's Disease Patients: A Study on Native Hawaiians and Pacific Islanders.

Department of Neurology, Hawaii Pacific Neuroscience, Honolulu, USA.
Background: Cardiometabolic disorders may accelerate the progression of Alzheimer's disease (AD), potentially impacting ethnic-racial groups with a higher prevalence of diabetes, obesity, and cardiovascular disease, though limited data exists on Native Hawaiians and Pacific Islanders (NHPI) populations.
Objective: This study aims to examine the prevalence of diabetes and associated comorbidities among AD patients from different ethnic-racial groups - Asians, Whites, and NHPIs - in Hawaii, with a focus on identifying risk factors linked to AD.
Method: A retrospective review was conducted on AD patient records from a single center in Hawaii, spanning June 2018 to June 2024.
Patients presenting with severe acute cardiogenic pulmonary edema with hypoxia commonly require intubation until heart failure treatments take effect. A new term describing similar condition is called sympathetic crashing acute pulmonary edema (SCAPE). It is also called Flash pulmonary edema.

To investigate the incidence rate, risk factors, and clinical implications of postoperative pulmonary complications (PPCs) in patients undergoing colorectal cancer surgery (CRC). The study extracted data from the National Inpatient Sample (NIS) between 2010 and 2019. Patients' data were analyzed to identify predictors of PPCs, and the association between possible factors and PPCs were also assessed.

Objective: To evaluate the effect of hyperbaric oxygen (HBO) therapy on the outcomes of patients with chronic refractory osteomyelitis (CRO) when combined with modern antibiotics with modern delivery methods and/or surgical treatments.
Methods: The authors conducted a retrospective review on 58 patients with CRO from a single institution who underwent HBO therapy along with standard treatment between January 2009 and December 2019. To investigate associations with binary outcomes of interest, they estimated logistic regression models.
Enhancing Thromboembolic Risk Prediction in Non-valvular Atrial Fibrillation: The Critical Role of Transesophageal Echocardiography (TEE).

Cardiology, Avicenna Military Hospital, Marrakesh, MAR.
Introduction Atrial fibrillation (AF), the most common cardiac arrhythmia, poses challenges in predicting thromboembolic risk. While the CHADS-VASc (congestive heart failure, hypertension, age ≥ 75 years (doubled), type 2 diabetes mellitus, previous stroke, transient ischemic attack, or thromboembolism (doubled), vascular disease, age 65-74 years, and sex category) score remains essential, its limitations include failure to identify left atrial (LA) thrombus in some patients. Transesophageal echocardiography (TEE) provides superior detection of LA thrombi and thrombogenic factors compared to transthoracic echocardiography (TTE), improving risk stratification, especially in intermediate-risk groups.
