Primary hyperparathyroidism is a common endocrinopathy. Multiple Endocrine Neoplasia Type 1 (MEN1) is a rare autosomal dominantly inherited endocrine tumor predisposition syndrome, with one of main manifestations being primary hyperparathyroidism. We retrospectively evaluated a set of 1011 patients who underwent surgery for primary hyperparathyroidism between the years 2018-2022, and found 78 (8 %) patients who underwent reoperations and 27 patients with MEN1 syndrome.

Article Synopsis
  • Life-prolonging therapies (LPTs) for advanced prostate cancer are becoming more prevalent, but the factors influencing patient access in real-world settings are not well understood.
  • A study examined 3,575 prostate cancer patients in Ontario who died between 2013 and 2017, finding that 40.4% received LPT, with usage increasing yearly, especially among those treated at Regional Cancer Centers and those who had prior prostate therapy.
  • Key factors affecting LPT access included age, chronic health conditions, and residence in long-term care, while income and distance to care did not play a significant role.

is one of the most common Gram-negative pathogens and is responsible for infection leading to neonatal meningitis and sepsis. The FtsZ protein is a bacterial tubulin homolog required for cell division in most species, including . Several agents that block cell division have been shown to mislocalise FtsZ, including the bacteriophage λ-encoded Kil peptide, resulting in defective cell division and a filamentous phenotype, making FtsZ an attractive target for antimicrobials.

Objective: The aim: To study the state of the intestinal microbiota (ІМ) in patients with Nonalcoholic fatty liver disease (NAFLD) and to determine changes in its composition at the level of basic phylotypes.

Patients And Methods: Materials and methods: The study included 114 patients with NAFLD with metabolic disorders and 64 patients of control group. Determination of the composition of the ІМ at the level of major phylotypes was performed by identifying total bacterial DNA and DNA of Bacteroidetes, Firmicutes and Actinobacteria by quantitative polymerase chain reaction (PCR) in real time (qRT-PCR) using universal primers for the 16S rRNA gene and taxon-specific primers of production (Thermo Fisher Scientific).

Optimal therapy of biochemically relapsed prostate cancer (BRPC) after local treatment is elusive. An established modified citrus pectin (PectaSol, P-MCP), a dietary polysaccharide, is an established antagonist of galectin-3, a carbohydrate-binding protein involved in cancer pathogenesis. Based on PSA dynamics, we report on the safety and the primary outcome analysis of a prospective phase II study of P-MCP in non-metastatic BRPC based.

Background: Several studies assessed the association of docetaxel dose intensity (DI) and efficacy in metastatic castrate-resistant prostate cancer (mCRPC) patients with contradicting conclusions. In this retrospective analysis, we will assess whether the docetaxel DI used in patients with metastatic castrate-sensitive prostate cancer (mCSPC) is associated with overall survival (OS).

Methods: All patients with mCSPC treated at The Ottawa Hospital Cancer Centre that received docetaxel chemotherapy between June 2014 and September 2017 were identified.

Docetaxel pharmacokinetics are affected by androgen deprivation therapy (ADT), which is attributed to changes in liver metabolism induced by castration. In this retrospective analysis, we assessed whether initiating docetaxel treatment in close proximity to the start of ADT therapy for metastatic castrate-sensitive prostate cancer (mCSPC) is associated with more treatment-related toxicity. We identified all patients with mCSPC treated at The Ottawa Hospital that received docetaxel chemotherapy between June 2014 and September 2017.

Neoadjuvant chemotherapy for osteosarcoma is the standard of care, but there is still confusion regarding the best chemotherapy regimen and the optimal intensity. This retrospective study intends to evaluate whether there is a clear correlation between the chemotherapy dose intensity (DI) and the percentage of tumor necrosis, the risk of tumor recurrence after surgery and patient survival. The medical records of all adult patients with localized osteosarcoma that received treatment between the years of 1998 and 2009 at the Tel Aviv Sourasky Medical Center were analyzed.
