The source of net ultrafiltration during hemodialysis is mostly the extracellular space regardless of hydration status

Abstract Fluid shifts are common in patients undergoing chronic hemodialysis (HD) during the intradialytic periods, as several liters of fluid are removed during ultrafiltration (UF). Some patients have experienced frequent intradialytic hypotension (IDH). However, the characteristics of fluid shifts and which fluid space is affected remain controversial. Therefore, we designed this study to evaluate the fluid spaces most affected by UF and to determine whether hydration status influences the fluid shifts during HD. This was a prospective cohort study of 40 patients undergoing HD. We measured the patient's fluid spaces using a whole‐body bioimpedance apparatus to evaluate the changes in the fluid spaces before HD and 1–4 hours of HD and 30 minutes after HD. UF achieved during HD by the 40 patients (age, 60.0 ± 5.2 years; 50% men; 50% of patients with diabetes; body weight, 61.3 ± 10.5 kg) was 2.18 ± 0.78 L (measured fluid overload, 2.15 ± 1.24 L). 1) Mean relative reduction of total body water and extracellular water was reduced from the start to the end of HD. 2) However, mean relative reduction of intracellular water was not reduced from the start to the end of HD. 3) No significant differences in fluid shifts were observed according to hydration status. The source of net UF during HD is mostly the extracellular space regardless of hydration ...

AbstractBullous pemphigoid (BP) is the most common autoimmune subepidermal bullous diseases. Autoantibodies against hemidesmosomal adhesion proteins might be involved in the developing process. BP usually affects the elderly with high mortality whereas the drug-induced BP is often improved and rarely relapses after the withdrawal of the suspected drug. An accumulated evidence suggests that dipeptidyl peptidase-4 inhibitor (DPP-4I), which has been widely used as the antidiabetic drug improves glycemic control with little risk for hypoglycemia, could be an inducer of DPP-4I-associated BP (DPP-4I-BP). While the precise mechan...

ConclusionsLung cancer surgery for HD patients provides favorable long-term outcomes despite higher postoperative mortality and morbidity rates. As an extended operation is significantly associated with postoperative complications, thoracic surgeons should carefully select the type of resection based on a balance between the therapeutic benefit and invasiveness in these patients.

CONCLUSION: The baseline diameter of the cephalic vein was the only predictor of arteriovenous fistula maturation based on the pre-operative ultrasound measurements in Chinese hemodialysis patients. PMID: 31884877 [PubMed - as supplied by publisher]

We describe the first case worldwide of capillary hemangioma that was a true vascular tumor arising from the lesser omentum. Although capillary hemangioma arising from the lesser omentum is extremely rare, it should be considered in the differential diagnosis of patients presenting with a highly enhanced lesser omental tumor, and laparoscopy can be safely applied for the excision of this tumor.

Rationale: Peripheral arterial diseases (PADs) is defined as a systemic arterial disorders involving the lower extremity arteries, iliac, and carotid, which is developed more common in patients with chronic kidney disease (CKD) than individual with normal renal function. Concurrence of mesenteric artery disease and lower extremity artery disease (LEAD) is rare. The presence of PADs in patients receiving hemodialysis leads to a dramatic increase in risk of cardiovascular mortality. However, the early diagnosis of PADs in patient with CKD remains a challenge to nephrologists, which adds an adverse effect on prognosis. Pat...

Authors: Morovatdar N, Tayebi Nasrabad G, Tsarouhas K, Rezaee R Abstract Introduction: End-stage renal disease (ESRD) is one of the most common life-threatening diseases. In the past two decades, several factors were held responsible as the cause of this condition. The present study aimed to determine the causes of ESRD in the province of Khorasan Razavi, Iran. Materials and Methods: This cross-sectional study was conducted on 2404 ESRD patients who referred to 39 hemodialysis centers in Khorasan Razavi province, Iran, and were registered in the Mashhad University of Medical Sciences (MUMS), between 2000 and De...
