Can Catheter Dormancy Be the Only Risk Factor for Delayed Small Bowel Perforati...

With the progression of chronic kidney disease (CKD), it is sensible to prepare patients for the need for renal replacement therapy. Peritoneal dialysis (PD) remains an advantageous option for those with residual kidney function and those who seek treatment adaptable to their daily routine. Timely catheter insertion is recommended to reduce the risk of peri-catheter leak associated with urgent-start PD. We pres...

ANCA Renal Risk Score in a Portuguese Cohort: Insights and Comparison with Berd...

Introduction: Antineutrophil cytoplasmic antibody (ANCA) ‑associated vasculitis (AAV) is a rare cause of glomerulonephritis. Despite advances in immunosuppressive therapies, AAV with renal involvement often leads to poor renal outcomes and a high ‑risk of end ‑stage renal disease (ESRD). Berden classification categorizes renal histology in four classes, but performance varies across cohorts. A lack of precise f...

Harmful Algal Blooms on the Portuguese coast: Cross-checking events with remote...

Phytoplankton plays a vital role in marine ecosystems, serving as a primary food source for a diverse array of organisms, including commercially important bivalves, crustaceans, and fish. However, in some situations, the proliferation of algae can cause serious economic losses for aquaculture, fishing, and tourism and have major environmental and human health impacts. Increases in the occurrence of toxic phytop...

Viral genetic clustering and transmission dynamics of the 2022 mpox outbreak in...

Pathogen genome sequencing during epidemics enhances our ability to identify and understand suspected clusters and investigate their relationships. Here, we combine genomic and epidemiological data of the 2022 mpox outbreak to better understand early viral spread, diversification and transmission dynamics. By sequencing 52% of the confirmed cases in Portugal, we identified the mpox virus sublineages with the hi...

A decoding algorithm for 2D convolutional codes over the erasure channel

Two-dimensional (2D) convolutional codes are a generalization of (1D) convolutional codes, which are suitable for transmission over an erasure channel. In this paper, we present a decoding algorithm for 2D convolutional codes over such a channel by reducing the decoding process to several decoding steps applied to 1D convolutional codes. Moreover, we provide constructions of 2D convolutional codes that are spec...

Noncatastrophic convolutional codes over a finite ring

Noncatastrophic encoders are an important class of polynomial generator matrices of convolutional codes. When these polynomials have coefficients in a finite field, these encoders have been characterized as polynomial left prime matrices. In this paper, we study the notion of noncatastrophicity in the context of convolutional codes when the polynomial matrices have entries in the finite ring Zpr. In particular,...
