Purpose: Two randomized clinical trials (STOMP and ORIOLE) demonstrated that stereotactic ablative radiotherapy (SABR) can prolong ADT-free survival or progression-free survival (PFS) in patients with metachronous oligometastatic prostate cancer (omCSPC) patients. While most omCSPC patients have a more modest delay in progression, a small subset achieves a durable response following SABR. We investigated the prognostic and predictive value of circulating PSMA-positive extracellular vesicles (PSMA+EV) and prostate specific antigen (PSA) in a biomarker correlative study using blood samples from three independent patient cohorts.

Klebsiella pneumoniae is an opportunistic pathogen responsible for various infections in humans and animals. It is known for its resistance to multiple antibiotics, particularly through the production of Extended-Spectrum Beta-Lactamases (ESBLs), and its ability to form biofilms that further complicate treatment. This study aimed to isolate and identify K.

Background: Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), are chronic conditions with complex etiologies that may involve dietary factors. This study investigates the association between fruit and vegetable consumption and the risk of UC and CD, focusing on gender-specific differences.

Methods: A hospital-based case-control study, comprising 158 UC patients (93 men and 65 women), 245 CD patients (167 men and 78 women), and 395 controls without IBD (256 men and 139 women), was conducted in Riyadh, Saudi Arabia.

: Prostate cancer treatment has been revolutionized by targeted therapies, including PARP inhibitors, checkpoint immunotherapies, and PSMA-targeted radiotherapies. Despite such advancements, accurate patient stratification remains a challenge, with current methods relying on genomic markers, tissue staining, and imaging. Extracellular vesicle (EV)-derived proteins offer a novel non-invasive alternative for biomarker discovery, holding promise for improving treatment precision.

The Klein-Gordon problem (KGP) is one of the interesting models that appear in many scientific phenomena. These models are characterized by memory effects, which provide insight into complex phenomena in the fields of physics. In this regard, we propose a new robust algorithm called the confluent Bernoulli approach with residual power series scheme (CBCA-RPSS) to give an approximate solution for the fractional nonlinear KGP.

Skin wounds can drive global impacts, socially and economically, in parallel with their elevated incidence rate. Therefore, utilizing the dual-activity of Brassica Oleracea (Red Cabbage) extract, of being pH-sensitive and biologically active in designing novel, therapeutic, and pH-sensitive wound dressings with an easily stripped-off feature, is critical. Wound dressings were designed using two separate hydrogels based on chitosan (CS) and hydroxyethylcellulose (HEC), each loaded with RCE.

Immune-mediated polyarthritis (IMPA) has a relatively high relapse rate compared to other immune-mediated diseases. Leflunomide is frequently used to treat dogs with IMPA in conjunction with prednisolone. This retrospective cohort study aimed to evaluate the therapeutic efficacy of leflunomide as an adjunctive therapy to prednisolone in reducing relapse and mortality rates in dogs diagnosed with IMPA in Australia.

In this narrative review, we summarized evidence from peer-reviewed articles, published before February 2024, that investigated lifestyle behaviors among children (≤12 years) and adolescents (13-18 years) representing different geographic descents. These behaviors included dietary patterns, screen time, physical activity, smoking, alcohol consumption, oral hygiene, unsafe sex, and sleep duration and quality. We documented the significant impacts of parental, school, and sociodemographic factors on the adoption of numerous lifestyle behaviors in this age category.

This study investigates the role of dietary Bacillus subtilis and oregano essential oil in mitigating the effects of high stocking density on growth performance, carcass traits, physiological stress indicators, gene expression, and intestinal integrity in broiler chickens. A total of, 1250 one-day-old Ross 308 male broiler chicks were randomly allocated to five experimental groups, where each group had five replicates of 50 chicks. Group 1 (control, LSD): 15 chicks/m fed a basal diet without feed additive, group 2 (HSD): 20 chicks/m fed a basal diet without feed additive, group 3 (BHSD): 20 chicks/m fed a basal diet supplemented with B.

Article Synopsis
  • Several genotypes of the highly pathogenic avian influenza (HPAI) virus H5N8 are circulating among domestic birds in Egypt, with quail playing a key role in its replication and potential adaptation to humans.
  • This study involves genetic characterization of H5N8 isolated from a commercial quail farm, revealing high genetic similarity to other circulating strains in Egypt and features indicating increased virulence in mammals.
  • Findings highlight the absence of antiviral resistance markers and underscore the need for continuous surveillance and genomic analysis of avian influenza in diverse bird species in Egypt for effective control measures.

Metastases to the brain are rare in prostate cancer. Here, we describe a patient with two treatment-emergent metastatic lesions, one to the brain with neuroendocrine prostate cancer (NEPC) histology and one to the dural membrane of adenocarcinoma histology. We performed genomic, transcriptomic, and proteomic characterization of these lesions and the primary tumor to investigate molecular features promoting these metastases.

There is still disagreement on the best treatment option for cholecystocholedocholithiasis. Although there are some benefits to the single-step procedure, the "laparoendoscopic rendezvous" (LERV) technique that include a lower risk of post-ERCP pancreatitis and a shorter hospital stay, the standard technique is still the two-step approach for clearing the common bile duct (CBD) using ERCP and then performing a laparoscopic cholecystectomy. The purpose of this study was to assess the effectiveness and safety of the LERV technique vs.
