Transplant renal artery stenosis (TRAS) is one of the common vascular complications post kidney transplantation. A retrospective study of TRAS among transplant recipients at a single transplant center in Thailand was performed from February 1986 to December 2002. Among 750 cases, 16 cases (2.1%) of TRAS were identified. Twelve cases (3.3%) were from cadaveric donors and four cases (1%) were from living-related donors (p-value = 0.034). Most cases presented with progressive deterioration of kidney graft with or without refractory hypertension. Doppler ultrasonography was used for initial screening followed by renal angiography. Fifteen cases were treated by Percutaneous Transluminal Angioplasty (PTA) with a 73 per cent success rate. Five cases underwent surgical revascularization with an 80 per cent success rate. Two cases (13%) of successful PTA showed recurrent stenosis with 46 months follow-up which were successfully treated by repeated PTA with stents.

Introduction: Immune checkpoint inhibitors (ICI) have improved the therapeutic arsenal in outpatient oncology care; however, data on necessity of hospitalizations associated with immune-related adverse events (irAEs) are scarce. Here, we characterized hospitalizations of patients undergoing ICI, from the prospective cohort study of the immune cooperative oncology group (ICOG) Hannover.
Methods: Between 12/2019 and 06/2022, 237 patients were included.

Background: We investigated factors associated with post-transplant growth in pediatric kidney transplant (KTx) recipients with a focus on plasma bicarbonate (HCO3) and estimated the effect of alkali treatment on growth.
Methods: In this study of the CERTAIN Registry, data were collected up to 5 years post-transplant. Generalized Additive Mixed Models were applied to assess the association between post-transplant growth and covariates.

Plasma cell disorders represent a spectrum of complex diseases, ranging from benign conditions to malignancies. The monoclonal immunoglobulins produced in these disorders can result in various renal pathologies, which may present as differing degrees of renal insufficiency. In severe instances, patients may necessitate dialysis or kidney transplantation.

Ceftobiprole, an advanced-generation cephalosporin with broad bactericidal activity, is approved for community-acquired and hospital-acquired pneumonia (excluding ventilator-associated pneumonia). We aimed to evaluate, in a real-world setting, the safety profile of ceftobiprole in patients with risk conditions (severe renal impairment, hepatic impairment, and immunocompromised status), groups excluded from clinical trials. In this retrospective study (NCT04170309), 396 consecutive charts of patients treated with ceftobiprole during 2016-2022 in 15 centers in France, Italy, and Spain were analyzed: 62 had severe renal impairment, 51 had hepatic impairment, 120 were immunocompromised, and 203 had no predefined risk condition (controls).
