Alzheimer's Disease (AD) is physiopathologically marked by an accumulation of beta-amyloid peptide (Aβ), hyperphosphorylation of tau protein, inflammation, and oxidative stress in the brain tissue. While new drugs for AD have been approved, novel treatments are still needed. Eplingiella fruticosa (EF) has demonstrated anti-inflammatory and antioxidant properties, which may be beneficial against AD.

Orofacial pain affects 10-15% of adults and can severely impact quality of life. Despite ongoing treatment challenges, monoterpene alpha-phellandrene (PHE) shows potential therapeutic benefits. This study aimed to develop and evaluate an inclusion complex of PHE with hydroxypropyl-beta-cyclodextrin (PHE-HPβCD) for treating orofacial pain.

Neuropathic pain is a high-intensity pain that can be caused by compression, transection, injury, nerve infiltration and drug treatment of cancer. Furthermore, drug therapy has low clinical efficacy, many adverse effects and remission of painful symptoms. In this way, natural products derived from plants constitute a promising therapeutic alternative.

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis (Mtb), which remains a significant global health challenge. The emergence of multidrug-resistant (MDR) Mtb strains imposes the development of new therapeutic strategies. This study focuses on the identification and evaluation of potential inhibitors against Mtb H37Ra through a comprehensive screening of an in-house chemolibrary.

Background: High-alert medication (HAM) is more predictable to cause significant harm to the patient, even when used as intended. The damage related to the HAM lead not only suffering to the patient, but also raise the additional costs associated with care.

Objective: Evaluate the incidence of drug-related adverse events related to the use of high-alert medications.

This study provides a comprehensive overview of the current knowledge regarding phototoxic terrestrial plants and their phototoxic and photosensitizing metabolites. Within the 435,000 land plant species, only around 250 vascular plants have been documented as phototoxic or implicated in phototoxic occurrences in humans and animals. This work compiles a comprehensive catalog of these phototoxic plant species, organized alphabetically based on their taxonomic family.

Edema is one of the obvious indicators of inflammation and a crucial factor to take into account when assessing a substance's capacity to reduce inflammation. We aimed to evaluate the antiedematogenic and anti-inflammatory profile of the hydroethanolic barks extract of Ximenia americana (HEXA). The possible antiedematogenic and anti-inflammatory effect of EHXA (50, 100 mg/kg and 250 mg/kg v.

Pain is one of the most prevalent and difficult to manage symptoms in cancer patients, and conventional drugs present a range of adverse reactions. The development of β-cyclodextrins (β-CD) complexes has been used to avoid physicochemical and pharmacological limitations due to the lipophilicity of compounds such as p-Cymene (PC), a monoterpene with antinociceptive effects. Our aim was to obtain, characterize, and measure the effect of the complex of p-cymene and β-cyclodextrin (PC/β-CD) in a cancer pain model.

Article Synopsis
  • The genus, comprising 282 species, is widely used in folk medicine across Brazil and other tropical American countries to treat conditions like rheumatoid arthritis, pain, and inflammation.
  • This review systematically discusses the therapeutic potentials and molecular mechanisms of 14 species from the genus, highlighting their anti-inflammatory, analgesic, and antioxidant properties, alongside safety evaluations of their consumption.
  • Key findings revealed that species such as Sw. Triana and (Bonpl.) DC show beneficial effects by modulating cytokines and inhibiting inflammatory mediators, though more studies are needed to fully understand their safety and efficacy.

Article Synopsis
  • This study assessed SARS-CoV-2 infection rates among urban cleaning and waste management workers in Sergipe, Brazil, during the Omicron variant surge.
  • Out of 494 workers tested, 22.5% were found to be infected, with younger workers and those skeptical of vaccine efficacy showing higher prevalence rates.
  • The findings highlight the urgent need for improved preventive measures and education about COVID-19 among these high-risk workers.

Background: Cancer is a major public health problem that imposes limitations on patients being treated. One of the strategies to improve health outcomes in cancer patients and promote the safety of their treatment is the provision of pharmaceutical clinical services (PCS). However, there is no evidence of health outcomes that are influenced by such services.
