Summary: This study aimed to explore the feasibility of using deep learning-based analysis of auscultation data to predict significant stenosis of arteriovenous fistulas (AVF) in hemodialysis patients. The results showed that using mel spectrogram-based deep convolutional neural network models can successfully predict the presence of significant AVF stenosis requiring percutaneous transluminal angioplasty (PTA).

Summary: This study aimed to investigate the clinical features and outcomes of craniocervical venous hypertensive myelopathy (VHM) caused by arteriovenous fistulas. The results showed that the Venous Hypertensive Myelopathy Scale (VHMS) had a higher correlation with the other two scales, and age over 65 years was identified as an independent predictor of delayed neurological decline. Recurrence increased the risk of adverse events after surgery.

Summary: Arteriovenous fistula (AVF) is the preferred vascular access for chronic hemodialysis, but its high failure rates limit its use. Neointimal hyperplasia (NIH) is a predominant cause of AVF failure, and systemic therapies have not shown clear benefits. Localized therapeutic approaches can improve AVF maturation rates by providing structural and functional support, as well as by delivering higher doses of drugs without systemic adverse effects.

Summary: This study compared the maturation and patency rates between percutaneous arteriovenous fistulas (pAVFs) created with the Ellipsys device and surgical arteriovenous fistulas (s-AVFs). pAVFs showed superior maturation rates, while s-AVFs had higher primary patency rates at 12 months. However, primary patency was comparable between the two groups at 24 months. s-AVFs required more frequent surgical revision and had more infection issues.

Summary: In this cohort of peritoneal dialysis patients, the utilization of backup arteriovenous fistulas was higher than previously reported, and the presence of backup arteriovenous fistulas was associated with a lower rate of future catheter use.

Summary: In hemodialysis patients with AV fistula, routine measurement of Kt/V during online HDF procedures is beneficial for early detection of hemodynamically significant stenosis in AV fistula. After angioplasty, there was a significant improvement in Kt/V in the active group, with no statistically significant differences in Kt/V between the two groups at 3 and 8 weeks post-procedure.

Summary: The study shows that for patients over 67 years old, peritoneal dialysis (PD) has a significant advantage over in-center hemodialysis in terms of Medicare expenditures, although there is no significant difference in the dialysis modality. Over time, the gap in dialysis expenditures gradually narrowed, while the gap in nondialysis expenditures widened.

Summary: Pleuroperitoneal fistula is a rare condition that occurs in approximately 1.6% of peritoneal dialysis patients. The cause of this condition is unknown, but it is often associated with increased abdominal pressure. Patients with pleuroperitoneal fistula present with acute dyspnea, cough, and decreased ultrafiltration rate, and analysis of pleural fluid reveals a transudate with elevated glucose concentration. We report a case of an 81-year-old woman with a history of peritoneal dialysis who presented with recurrent pleural effusion. Peritoneal scintigraphy with Tc-99m confirmed the diagnosis of pleuroperitoneal fistula.

Summary: The study showed that compared to non-weighted catheters, patients with weighted catheters had lower rates of acute (30.3% vs. 9.8%, p=0.03) and chronic laxative use (36.4% vs. 12.2%, p<0.02). Weighted catheters also performed better in secondary outcomes (dislocations: 45.5% vs. 12.2%, p=0.001).

Summary: This study provides the first real-world based estimation of the prevalence of chronic kidney disease (CKD) in a large, unselected Portuguese population. The overall estimated prevalence of CKD was 9.8% and was higher in females than males. This study may help healthcare providers in formulating policies and strategies focused on preventing CKD and improving cardiovascular outcomes.

The analysis of various risk factors showed that microbial identification does not lower hospital mortality, regardless of the risk for drug-resistant pathogens.

Summary: This study evaluated the relationship between urinary cysteinyl leukotrienes (U-CysLT) and disease severity in COVID-19 patients, and their usefulness for prognosis assessment. The impact of veno-venous extracorporeal membrane oxygenation (VV-ECMO) and comorbidities such as hypertension and obesity on U-CysLT was also assessed. The results showed that U-CysLT increased significantly during hospitalization, especially in critical groups and VV-ECMO patients, particularly those with hypertension. The association of U-CysLT with severe outcomes suggests their potential value in prognosis assessment and as therapeutic targets.

Summary: The aim of this study was to assess the exposure of pregnant women in Portugal to 3-phenoxybenzoic acid (3-PBA) and its association with maternal outcomes and newborn anthropometric measures. The study found that pregnant women in Portugal are exposed to 3-PBA, particularly during summer, and this exposure may be associated with maternal clinical features.

Summary: This study compared measured creatinine clearance (MCC) with estimated creatinine clearance obtained through different formulas in neurocritical patients with traumatic brain injury or subarachnoid hemorrhage. It also assessed the incidence of augmented renal clearance (ARC) in this population. The study found a weak statistical correlation between measured and estimated methods, and the formulas underestimated MCC in patients with ARC.

Summary: Subsyndromal delirium (SSD) in the Intensive Care Unit (ICU) is associated with increased morbidity and unknown post-discharge functional and cognitive outcomes. A multicenter study found that early SSD patients experienced a decline in cognitive abilities at 3 months after discharge, but showed improvement at 6 months. Therefore, preventing and identifying SSD during ICU stays is crucial.

Summary: This study aims to predict the adherence behavior of patients with Type 1 Diabetes to intermittently scanned continuous glucose monitoring (isCGM). The findings suggest that age, time in target, isCGM necessity, body mass index, and sex are predictors of adherence. Therefore, personalized strategies should be implemented to promote treatment adherence in patients with these characteristics.

Summary: This systematic review and meta-analysis examined the association between aspirin use and bleeding during percutaneous kidney biopsy (PKB). The results showed no significant difference in major bleeding events between the aspirin-exposed and nonexposed groups. However, high-quality evidence on the effect of aspirin on the bleeding risk is limited, and further studies are needed to define a more comprehensive approach for clinical practice.

Summary: This study explores the value of community-based strategies in sustaining the effects of pulmonary rehabilitation for patients with chronic respiratory diseases. The findings suggest that maintaining an independent and active lifestyle, along with motivation and professional and peer support, are key elements in sustaining the benefits of pulmonary rehabilitation.
