Effective pain management has long been hindered by the limitations and risks associated with opioid analgesics, necessitating the exploration of novel, non-opioid alternatives. A comprehensive literature search was conducted using PubMed and Google Scholar during October and November 2024 to identify studies on emerging non-opioid pain management therapeutics. This review evaluates three promising classes of mechanism-specific therapeutics: nerve growth factor (NGF) monoclonal antibodies, transient receptor potential vanilloid 1 (TRPV1) antagonists, and selective sodium channel blockers.

Objective: To assess the feasibility and possible impacts of implementation of systematic non-pharmacological interventions to reduce the level of prescribing of opioid and gabapentinoid analgesics for chronic non-cancer pain (CNCP), particularly high-dose prescriptions, through a proof-of-concept study in a deprived area (second lowest decile) primary care practice in North-East England.

Participant: Twenty-five primary care staff (clinical and non-clinical) of which 18 clinicians received the intervention.

Intervention Used In This Study Practice Known As Gott Gabapentinoid And Opioid Toolkit: All clinicians received an educational skills programme to support patient pain self-management, tailored on the clinicians' self-assessment of their learning needs, embedding both clinician skill learning and patient self-care resources for rapid access within consultations into a GP clinical management computer system.

Article Synopsis
  • The SARS-CoV-2 pandemic has highlighted how quickly viruses can mutate, leading to new variants like Delta and Omicron, which have changes in their spike protein that enhance their ability to infect and evade immunity.
  • Researchers examined how well antibodies (IgG) from recovered COVID-19 patients bind to Delta and Omicron variants compared to the original strain.
  • The study found that while there's significant antibody response to Omicron, responses to Delta were not significantly different from pre-pandemic controls, indicating a substantial level of cross-reactivity of antibodies to both variants.

Background: Quality improvement (QI) is used by healthcare organisations internationally to improve care. Unless QI explicitly addresses equity, projects that aim to improve care may exacerbate health and care inequalities for disadvantaged groups. There are several QI frameworks used in primary care, but we do not know the extent to which they consider equity.

Background: An unequal distribution of the social determinants of health drives health inequalities. Existing training fails to communicate the impossible circumstances that disadvantaged groups face. Game-based learning is increasingly used as an innovative method with the potential to enhance health staff's ability to address health inequalities, but its effectiveness is unknown.

Background: Selective serotonin reuptake inhibitors (SSRIs) are used for the management of anxiety and depression. Existing evidence shows their negative impact on implant osseointegration, survival rates, and peri-implant health. Currently, there are limited data on their effect on peri-implant marginal bone levels.

The Covid-19 pandemic has required many anthropologists to do fieldwork differently: research that would otherwise have been done face-to-face has been shifted online, sometimes very quickly. When doing research with people with chronic illnesses, it is important to acknowledge both the histories of online ethnography and the way that disability studies has engaged with the internet over time. This article uses the example of my PhD fieldwork, based in Northeast England, to explore how living in an increasingly digital world may impact how medical anthropologists could, and perhaps should, do ethnography.

Repurposing approved drugs may rapidly establish effective interventions during a public health crisis. This has yielded immunomodulatory treatments for severe coronavirus disease 2019 (COVID-19), but repurposed antivirals have not been successful to date because of redundancy of the target in vivo or suboptimal exposures at studied doses. Nitazoxanide is a US Food and Drug Administration (FDA) approved antiparasitic medicine, that physiologically-based pharmacokinetic (PBPK) modeling has indicated may provide antiviral concentrations across the dosing interval, when repurposed at higher than approved doses.

We describe a mathematical model of cell growth and death and explain how it can be used to integrate data from classic tissue culture experiments on antitumour agents and thus aid the identification of their mechanism of action. Experimental data relating to time- and dose-dependent changes in growth rate, cell cycle distribution, plus apoptotic and senescent fractions, are reinterpreted in terms of modulations to kinetic parameters that describe the rates at which cells transit between phenotypic compartments. The mathematical model is analytical, in the sense that the kinetic parameters are calculated from the experimental data directly, without any fitting process.
