Article Synopsis
  • The study evaluated the effectiveness of palbociclib, a targeted cancer therapy, in patients with advanced cancer exhibiting specific genomic alterations, focusing on two patient groups: those with head and neck cancer (HNC) and those with a mix of histologies (HP).
  • Results showed that 40% of the HNC patients achieved disease control, which was statistically significant, while only 13% of the HP cohort did, failing to meet the criteria for significance.
  • The treatment had notable side effects, with over 40% of patients experiencing serious adverse events, primarily blood-related issues like neutropenia and thrombocytopenia.

Purpose: The Targeted Agent and Profiling Utilization Registry Study is a phase II basket trial evaluating the antitumor activity of commercially available targeted agents in patients with advanced cancer and genomic alterations known to be drug targets. Results of a cohort of patients with various solid tumors with germline or somatic mutations treated with talazoparib are reported.

Methods: Eligible patients had advanced solid tumors, measurable disease (RECIST), Eastern Cooperative Oncology Group performance status 0-2, adequate organ function, and no standard treatment options.

Article Synopsis
  • The study evaluates the effectiveness of targeted agents, specifically pertuzumab plus trastuzumab, in patients with advanced biliary tract cancer (BTC) who have specific genomic alterations.
  • Out of 29 enrolled patients, the treatment showed a 40% disease control rate, with some experiencing significant responses, indicating potential benefits of this combination therapy.
  • Although the treatment was generally well-received, a few patients reported notable adverse events, highlighting the importance of monitoring safety alongside treatment efficacy.

Several studies in the last few years have determined that, in contrast to the prevailing dogma that drug resistance is simply due to Darwinian evolution-the selection of mutant clones in response to drug treatment-non-genetic changes can also lead to drug resistance whereby tolerant, reversible phenotypes are eventually relinquished by resistant, irreversible phenotypes. Here, using KRAS as a paradigm, we illustrate how this nexus between genetic and non-genetic mechanisms enables cancer cells to evade the harmful effects of drug treatment. We discuss how the conformational dynamics of the KRAS molecule, that includes intrinsically disordered regions, is influenced by the binding of the targeted therapies contributing to conformational noise and how this noise impacts the interaction of KRAS with partner proteins to rewire the protein interaction network.

Article Synopsis
  • The TAPUR Study evaluates the effectiveness of approved targeted agents, specifically pembrolizumab, in treating patients with advanced cancers that have specific genomic alterations, focusing on those with high tumor mutational burden (HTMB).
  • The study included 77 patients with advanced colorectal cancer (CRC) and other cancers, assessing outcomes like disease control and overall response rates; results showed a disease control rate of 31% for CRC and 45% for the pooled cohort.
  • It concluded that pembrolizumab is effective in demonstrating antitumor activity in patients who have already undergone treatment for advanced cancers with HTMB, although some patients experienced serious adverse effects.

Article Synopsis
  • The Targeted Agent and Profiling Utilization Registry Study is testing the effectiveness of targeted treatments for advanced lung cancer patients with specific genomic alterations.
  • The study involved 28 patients, primarily with non-small-cell lung cancer, who received a combination therapy of pertuzumab and trastuzumab, aiming for disease control and measuring various outcomes, including overall survival.
  • Results indicated a 37% disease control rate, with some patients showing a partial response, though there were also notable serious side effects from the treatment.

Adherence issues combined with inequitable access to healthcare may increase the risk of discontinuation of care for undocumented migrants with severe mental health illness. An Ethiopian man with paranoid schizophrenia who relapsed several times after hospitalization was identified by a humanitarian outreach team in Brussels. The team built a relationship with him by offering him access to services including accommodation and mental health care.

Background: The Post Natal Club (PNC) model assures comprehensive care, including HIV and Maternal and Child Health care, for postpartum women living with HIV and their infants during an 18-month postnatal period. The PNC model was launched in 2016 in Town Two Clinic, a primary health care facility in Khayelitsha, South Africa. This qualitative research study aims to understand how participation in PNCs affected knowledge transmission, peer support, behaviour change and satisfaction with the care provided.

Objective: To develop effective pharmacy-based interventions to mitigate harm from opioid use disorders. Programs include responsible opioid prescribing, expanded access to medication-assisted treatment (MAT), naloxone, and community interventions.

Setting: Clinical pharmacists practicing at Indian Health Service (IHS) locations in the Southwest, Midwest, and Great Lakes regions.

In response to the growing burden of drug-resistant tuberculosis (DR-TB) in South Africa (SA), Médecins Sans Frontières (MSF), with local government health departments, piloted a decentralised model of DR-TB care in Khayelitsha, Western Cape Province, in 2007. The model takes a patient-centred approach to DR-TB treatment that is integrated into existing TB and HIV primary care programmes. One essential component of the model is individual and family counselling to support adherence to and completion of treatment.

Background: Lengthy antiretroviral treatment (ART) preparation contributes to high losses to care between communicating ART eligibility and initiating ART. To address this shortfall, Médecins Sans Frontières implemented a revised approach to ART initiation counselling preparation (integrated for TB co-infected patients), shifting the emphasis from pre-initiation sessions to addressing common barriers to adherence and strengthening post-initiation support in a primary healthcare facility in Khayelitsha, South Africa.

Methods: An observational cohort study was conducted using routinely collected data for all ART-eligible patients attending their first counselling session between 23 July 2012 and 30 April 2013 to assess losses to care prior to and post ART initiation.

Equine inflammatory disease is accompanied by a neutrophil activation resulting in the release of granulocytic enzyme myeloperoxidase (MPO). To measure MPO in horse plasma as marker of neutrophil activation, the authors purified equine neutrophil MPO and developed a specific enzyme immunoassay using 2 specific polyclonal antibodies obtained from rabbit (primary antibody) and guinea pig (secondary antibody). The sandwich complex "primary antibody-MPO-secondary antibody" was detected using a goat anti-guinea pig immunoglobulin antibody conjugated to alkaline phosphatase.

A method is proposed (1) to create inhalation to perfusion ratio (I/Q) images from equine lung scintiscans and (2) to analyse these I/Q images. This method was applied to five healthy horses in order to establish reference ranges of I/Q distribution pattern. Computed I/Q images were divided in three regions based on the activity due to the inhalation (I) versus perfusion (Q) procedure.
