Sex differences and driving impairment related to psychoactive substances

OBJECTIVE

The first aim of the study was to identify sex differences in the use of psychoactive substances among subjects with a previous driving under the influence (DUI) episode. The secondary objective was to propose specific strategies for medico-legal improvements.

METHODS

This was a retrospective observational study that took place between June 1, 2019, and August 31, 2023. It was conducted on DUI subjects examined for reinstatement of their driver's license using an integrated medico-legal and toxicological approach. Ethyl glucuronide (EtG) and illicit psychoactive substances were determined from hair samples. We performed descriptive statistical analyses for the entire sample as well as separately by sex. Additionally, we conducted binary logistic regression analyses separately for males and females to identify protective/risk factors associated with previous road accidents and judgments of unfitness to drive due to excessive alcohol consumption (EtG ≥ 30 pg/mg).

RESULTS

The study included 2,221 subjects, comprising 1,970 men and 251 women. Men exhibited a higher prevalence of tobacco, alcohol, and illicit psychoactive substance use. Women were more frequently co-users of alcohol and psychoactive substances and involved in road accidents at the time of DUI. Among the men, being married or having a partner was found to be a protective factor concerning past traffic accidents. For both sexes, a DUI episode with a blood alcohol concentration (BAC) exceeding 1.5 g/L or the co-ingestion of alcohol and drugs was identified as a risk factor for road accident involvement. For men, smoking more than 20 cigarettes per day and, for women, having a DUI episode with a BAC over 1.5 g/L were the main factors indicating unfitness to drive, as determined through high hair EtG levels (> 30 pg/mg). Women with a previous history of road accidents were less likely to have EtG levels of 30 pg/mg or more.

CONCLUSIONS

The study confirmed sex differences in subjects with a previous DUI episode. A BAC exceeding 1.5 g/L or the simultaneous use of alcohol and drugs at the time of DUI necessitate careful assessment of both men and women seeking driver's license reinstatement. In women, a BAC exceeding 1.5 g/L is considered a risk factor for a subsequent judgment of unfitness to drive. The medico-legal assessment should also involve a thorough investigation of smoking habits in men, as these habits could be related to an increased risk of excessive alcohol consumption.

The Ethics of Screening and Treating Persons with Hepatitis C: A Canadian Perspective

In this article, I argue that the Canadian government’s position against screening for hepatitis C virus (HCV) and publicly funding HCV treatment is ethically unjustifiable. Cost of medication and likelihood of widening existing health inequality are the government’s argument for not funding HCV treatment and for also not having a screening program. I object to this position and argue in favour of a screening program and public funding of HCV treatment. I argue that these barriers are ethically unjust. Conclusively, being denied screening and early treatment is to be denied the best possible outcome.

The disconnect in hepatitis screening: participation rates, awareness of infection status, and treatment-seeking behavior

Background

Over 325 million people in the world are infected with hepatitis B or C virus. Chronic hepatitis is responsible for 78% of cases of hepatocellular carcinoma and an estimated 1.3 million preventable deaths a year. As “silent killers”, liver diseases are often asymptomatic and go undiagnosed until their terminal stage. Knowledge of infection status via screening is thus a vital part of preventing spread and seeking early treatment. Recently there has been a worldwide push to eliminate hepatitis. The objective of this study is to assess hepatitis B and C self-reported awareness of infection status vs correct awareness (compared to blood test results) and follow-up rates in Taiwan to inform global health promotion efforts that utilize screening interventions to prevent chronic liver diseases.

Methods

De-identified data from a Liver Foundation’s nationwide community-outreach free blood screening programs was utilized, including 50 909 participants’ data from 74 sites with a questionnaire (demographics, screening history, hepatitis awareness, monitoring behavior) and blood test results. Chi square tests were applied using R programing to examine the impacts of demographic variables on infection prevalence, awareness, and behavior relating to hepatitis.

Results

Among all participants, 41.1% indicated having had a hepatitis screening, of which only 60.8% knew their results. Around 69.7% and 66.5% self-reported awareness of their hepatitis B and C status respectively; 12.8% and 26.4% of individuals who tested positive for HBsAg and Anti-HCV respectively incorrectly thought they were not infected. Of those who self-reported awareness of their positive infection, 43.4% and 26.6% did not follow up with a health care professional for monitoring or treatment; the top reasons were “no symptoms”, “too busy”, and “don’t know where to follow up”. Rural populations showed higher infection prevalence but lower screening rates and self-reported awareness.

Conclusions

Intervention programs must address the substantial number of people that do not recall if they were screened or do not know the results of a screening. Discrepancies between self-reported awareness, correct awareness, and follow-up and disparities across demographic groups deserve further scrutiny. Global hepatitis eradication initiatives should reconsider how screening, test results, and education are presented in order to improve awareness and prevent chronic infection that could develop into life-threatening liver diseases.

A retrospective cohort study on the association between periapical abscess, advanced periodontal disease, and the national oral health screening program among Korean adults

The National Oral Health Screening Program (NOHSP) is a general population-based program in Korea. The objective of this study was to assess the association between participation in the NOHSP and dental visit for periapical abscess (PA) and advanced periodontal disease (APD) among Korean adults. Data were obtained for subjects from the National Health Insurance database. The authors conducted a retrospective cohort study of 9358 randomly selected subjects who were between 40 and 64 years old in 2002. The outcomes of dental visit for PA or APD from the years 2003 to 2007 were compared between the screening and nonscreening groups. The nonscreening group had 19% higher risk of PA and 15% higher risk of APD. This study suggests that the NOHSP may decrease the risk of dental visit because of PA and APD by preventing the progress of lesion to the advanced stage among Korean adults.

Context of clinical care: the case of hepatitis C in underserved communities--a report from the Primary Care Multiethnic Network (PRIME Net) Consortium

BACKGROUND

The importance of Hepatitis C (HCV) as a public and individual health concern is well established. However, national groups differ in their recommendations to primary care clinicians about screening people at high risk for HCV. The purpose of this study was to explore the context of care within which primary care clinicians decide to detect and initially manage HCV.

METHODS

The Primary Care Multiethnic Network conducted a web- and paper-based survey of primary care clinicians who largely practice in low-income, medically underserved communities in 3 regions across the country.

RESULTS

A total of 494 clinicians participated, for a response rate of 61%. Most (68%) clinicians view HCV as an important problem; more than half (59%) consider screening for HCV to be important when compared with other conditions they screen for in practice. With regard to reported screening habits for risk factors, 54% of clinicians routinely ask new patients whether they have used intravenous drugs and 28% inquire about blood transfusions before 1992. Sixty-one percent order an alanine aminotransferase test when patients present with other risk factors for HCV. The majority of clinicians (54%) refer 75% or fewer of their patients with HCV for treatment; nearly one-fifth (18%) provide antiviral treatment themselves. Key factors influencing clinician HCV decision making are patient comorbidities (74% reported this as a factor), access to treatment (55% reported this as a factor), and tolerance (44% reported this as a factor) of treatment.

CONCLUSIONS

In the face of conflicting national guideline recommendations about screening people at high risk for HCV, clinicians have varied views and practice habits influenced by multiple patient, access, and treatment issues.

Benefits and adverse effects of hepatitis C screening: early results of a screening program

OBJECTIVE

Early benefits and adverse effects of hepatitis C screening among people who screened anti-hepatitis C virus (HCV) positive were investigated.

METHODS

Hepatitis screening program records were abstracted to identify the target population and obtain information about hepatitis A and B vaccination (recommended vaccines if anti-HCV positive). Telephone interviews were conducted using a standardized questionnaire with items regarding clients' medical evaluation, behaviors to prevent liver damage and prevent HCV transmission, and adverse effects experienced.

RESULTS AND CONCLUSIONS

Of 269 eligible clients, 147 were susceptible to hepatitis A (IgG negative), and 116 (78.9%) received at least 1 hepatitis A vaccine dose. Of 119 clients susceptible to hepatitis B, 101 (84.9%) received at least one dose of hepatitis B vaccine. Fifty-six (20.8%) were reached by phone, and 44 (78.6%) consented to the interview. All interviewed clients reported one or more positive behaviors to protect their liver or prevent HCV transmission; 51.2 percent reported at least one adverse effect related to knowing their positive anti-HCV status, most commonly difficulty obtaining health insurance; and 86.0 percent reported satisfaction with their decision to be tested. Results suggest that most anti-HCV-positive clients had some benefit from screening, and highlight the need for further studies.
