Expanded hemodialysis (HDx) is an innovation that can increase the effectiveness of hemodialysis. The dialysis process is expected to promote more uremic toxins removal without causing significant hypoalbuminemia using the medium cut-off (MCO) membrane or also known as the high retention onset membrane. Compared with conventional membranes such as those of low-flux hemodialysis, high-flux hemodialysis, and hemodiafiltration, the MCO membrane in HDx is considered to be the closest to the physiology of the glomerular membrane. Several studies have shown the use of the MCO membrane in HDx provides clinical benefits and better outcome although further studies are needed to assess the long-term effect and greater impact for dialysis patients.

Multicenter Study
Prevalence and determinants of severity of uremic pruritus in hemodialysis patients: a multicentric study.
Uremic pruritus (UP) is a common and distressing symptom in patients with advanced or end-stage renal disease under hemodialysis (HD). The present multicentric study aimed to identify prevalence and determinants of severity of UP among Egyptian patients. Performed investigations included serum urea, creatinine, calcium, phosphorus, parathormone, ferritin and liver enzymes. ⋯ Independent predictors of significant UP included longer HD duration (OR: 1.23, 95% CI 1.1 to 1.38, p<0.001), lack of vitamin D supplementation (OR: 3.71, 95% CI 1.03 to 13.4, p=0.045), lower albumin levels (OR: 0.32, 95% CI 0.14 to 0.74, p=0.008) and higher hsCRP levels (OR (CRP): 1.02 (1.0-1.03), p=0.011). In conclusion, UP is fairly common among Egyptian HD patients. Independent predictors of UP severity include longer HD duration, lack of vitamin D supplementation, lower albumin levels and higher hsCRP levels.

Over 25% of veterans with Gulf War illness developed chronic gastrointestinal (GI) symptoms of unknown etiology after they returned from deployment to the Persian Gulf. To determine the prevalence of delayed gastric emptying and its association with autonomic dysfunction in returning Gulf War (GW) veterans with chronic GI symptoms, we prospectively studied 35 veterans who were deployed to the Persian Gulf and developed chronic nausea, vomiting, postprandial abdominal pain, and bloating during their tour of duty and 15 asymptomatic controls. All veterans underwent 5 standardized cardiovascular tests to assess autonomic function. ⋯ Our results suggest that autonomic dysfunction and delayed gastric emptying are common in returning GW veterans with GI symptoms. Autonomic dysfunction was positively correlated with the severity of delayed gastric emptying and may account for the GI symptoms of nausea, vomiting, postprandial abdominal pain, and bloating. These new findings are important for an increasing number of veterans who are serving in the Persian Gulf and are at a high risk of developing GI disorders while deployed.

Patients admitted via interhospital transfer (IHT) experience increased risk-adjusted mortality, adverse events, length of stay, and discharge to facility; however, the etiology is not well understood. We hypothesize that IHTs are more likely to experience in-hospital delirium as compared with admissions to the hospital via the emergency department (ED) and clinic. This is a cross-sectional study of all adult admissions to medical, surgical, neurological, and obstetrics and gynecology services at an academic medical center who were screened for delirium between August 2018 and January 2020. ⋯ Multivariable logistic regression adjusting for demographics and comorbidities showed that IHT admissions had higher odds (OR 1.91, 95% CI 1.74 to 2.10) and clinic admissions had lower odds (OR 0.56, 95% CI 0.48 to 0.64) of in-hospital delirium compared with ED admissions. Increased odds of delirium in IHT admissions may contribute to the observed increased length of stay, discharge to facility, and mortality. These results emphasize the importance of routine screening and possible intervention prior to patient transfer.
