Prevalence and correlates of medical student mistreatment in Nigeria: A narrative review

Mistreatment in medical education encompasses various forms of abusive behavior, often indicating a disregard for students' dignity and interfering with the learning process. This review paper aims to investigate the prevalence, patterns, and correlates of medical student mistreatment in Nigerian medical education and shed light on its impact on students' well-being. A literature search was conducted in August 2023 using Medline, Google Scholar, and Web of Science databases to identify relevant studies on the mistreatment of Nigerian medical students. Inclusion criteria encompassed all studies written in English, regardless of study design, while editorials, reviews, and opinion articles were excluded. Six studies with a total sample size of 1432 were included in the review. The review revealed high mistreatment rates, ranging from 46% to 91%, with verbal abuse being the most common form. Male students were more likely to experience mistreatment, while females had higher rates of sexual abuse. Perpetrators included male and female healthcare professionals, with consultants and resident doctors as common perpetrators. Age and study level were associated with mistreatment experiences. Consequences of mistreatment included emotional distress, depression, loss of self-confidence, academic disillusionment, substance abuse, and suicidal thoughts. Reporting rates were low due to a lack of awareness, fear of reprisal, and perceived futility. The findings underscore the need for institutions to create a supportive environment, raise awareness of available support systems, and implement policies to prevent mistreatment. Future research should focus on larger-scale studies with diverse samples and longitudinal designs to address limitations in the current literature.

Puff-resolved analysis and selected quantification of chemicals in the gas phase of E-Cigarettes, Heat-not-Burn devices and conventional cigarettes using single photon ionization time-of-flight mass spectrometry (SPI-TOFMS): A comparative study

INTRODUCTION

A wide array of alternative nicotine delivery devices (ANDD) has been developed and they are often described as less harmful than combustible cigarettes. This work compares the chemical emissions of three ANDD in comparison to cigarette smoke. All the tested ANDD are characterized by not involving combustion of tobacco.

METHOD

Single photon ionization time-of-flight mass spectrometry (SPI-TOFMS) is coupled to a linear smoking machine, which allows a comprehensive, online analysis of the gaseous phase of the ANDD aerosol and the conventional cigarette smoke (CC). The following devices were investigated in this study: a tobacco cigarette with a glowing piece of coal as a heating source, an electric device for heating tobacco and a first-generation electronic cigarette. Data obtained from a standard 2R4F research cigarette are taken as a reference.

RESULTS

The puff-by-puff profile of all products was recorded. The ANDD show a substantial reduction or complete absence of known harmful and potentially harmful substances compared to the CC. In addition, tar substances (i.e. semivolatile and low volatile aromatic and phenolic compounds) are formed to a much lower extent. Nicotine, however, is supplied in comparable amounts except for the investigated electronic cigarette.

CONCLUSIONS

The data shows that consumers switching from CC to ANDD are exposed to lower concentrations of harmful and potentially harmful substances. However, toxicological and epidemiological studies must deliver conclusive results if these reduced exposures are beneficial for users.

IMPLICATION

The comparison of puff-resolved profiles of emissions from different tobacco products, traditional and alternative, may help users switch to lower emission products. Puff-resolved comparison overcomes technical changes, use modes between products and may help in their regulation.
