MicroRNAs are a conserved class of small, tissue-specific, non-coding RNAs that regulate gene expression to preserve cellular homeostasis. Proper miRNA expression is crucial for physiological balance because it affects numerous genetic pathways, including cell cycle control, proliferation, and apoptosis, through gene expression targeting. Deregulated miRNA expression has been implicated in several cancer types, including prostate cancer (PC), acting as tumor suppressors or oncogenes. Despite the availability of promising therapies to control tumor growth and progression, effective diagnostic and therapeutic strategies for different types of cancer are still lacking. PC continues to be a significant health challenge, particularly its castration-resistant (CRPC) form, which presents major therapeutic obstacles because of its resistance to conventional androgen deprivation treatments. This review explores miRNAs' critical roles in gene regulation and cancer biology, as well as various miRNA delivery systems, highlighting their potential and the challenges in effectively targeting cancer cells. It aims to provide a comprehensive overview of the status of miRNA research in the fight against CRPC, summarizing miRNA-based therapies' successes and limitations. It also highlights the promise of miRNAs as therapeutic agents for CRPC, underlining the need for further research to overcome existing challenges and move these therapies toward clinical applications.

Heart failure (HF) is a multifactorial and pathophysiological complex syndrome, involving not only neurohormonal activation but also oxidative stress, chronic low-grade inflammation, and metabolic derangements. Central to the cellular defence against oxidative damage is nuclear factor erythroid 2-related factor 2 (Nrf2), a transcription factor that orchestrates antioxidant and cytoprotective responses. Preclinical in vitro and in vivo studies reveal that Nrf2 signalling is consistently impaired in HF, contributing to the progression of myocardial dysfunction.

Leishmaniasis, a disease caused by Leishmania parasites, poses a significant health threat globally, particularly in Latin America and Brazil. Leishmania amazonensis is an important species because it is associated with both cutaneous leishmaniasis and an atypical visceral form. Current treatments are hindered by toxicity, resistance, and high cost, driving the need for new therapeutic targets and drugs.

Background: After remission of a first-episode psychosis (FEP), antipsychotic discontinuation is associated with an increased risk of relapse compared to maintenance treatment. We studied short and longer-term effects of discontinuation of D receptor (DR) antagonist and partial agonist antipsychotics on striatal dopamine DR availability in FEP patients.
Methods: Remitted FEP patients underwent two [C]raclopride PET scans to measure striatal DR availability: 1 week after antipsychotic discontinuation (n = 16 antagonist users, n = 6 partial agonist users) and after being medication free for 6-8 weeks (n = 8 antagonist users, n = 5 partial agonist users).

Background: The Neria™ Guard infusion set is indicated for the infusion of several medications for Parkinson's and pain-management therapy.
Aim: The aim of this study was to explore the impact of the Neria Guard infusion set on patients and health professionals from the perspective of nurses.
Method: Two surveys were distributed to nurses: one targeting nurses who use Neria Guard for Parkinson's patients, and one for those who use it for palliative care patients.

Tuberculosis, caused by , persists as a significant worldwide health issue, resulting in millions of infections and fatalities each year. Treatment predominantly depends on first-line antibiotics, including Isoniazid (INH) and Rifampicin (RIF). Nevertheless, extended use of these medications is linked to considerable adverse effects, leading to various organ toxicities, especially hepatotoxicity and nephrotoxicity.
