Obstacles and facilitators to preventing fetal alcohol spectrum disorder: a qualitative study with general practitioners.

Background: Fetal Alcohol Spectrum Disorders are the leading cause of non-genetic intellectual disability. The damage caused, although completely preventable, is irreversible and requires lifelong support. General Practitioners have an important role in the prevention of Fetal Alcohol Spectrum Disorders. However, evidence suggests that General Practitioners do not monitor systematically alcohol consumption among pregnant women. Objectives: The aim of this study was to understand the barriers and motivations of General Practitioners in the prevention of Fetal Alcohol Spectrum Disorders on Reunion Island. Methods: A qualitative research study was conducted by conducting semi-structured individual interviews with general practitioners. Participants were selected by random or snowball sampling. General practitioners who worked only in unscheduled care services were excluded from this study. After the interviews were transcribed, a verbatim analysis was performed according to the principles of grounded theory. Results: Twenty interviews were conducted by two researchers between November and December 2020. General practitioners expressed discomfort in addressing alcohol consumption and excessive drinking in women. They had inaccurate theoretical knowledge and a lack of practical experience with Fetal Alcohol Spectrum Disorders. They also showed little knowledge of the Fetal Alcohol Spectrum Disorders care pathway available on Reunion Island. Both patients and general practitioners expressed discomfort when discussing women's alcohol consumption. Conflicting government policies were highlighted as alcohol promotion campaigns overshadowed Fetal Alcohol Spectrum Disorders prevention initiatives. Conclusion: General practitioners should be open and non-judgmental in their interactions with women and couples, with a focus on early detection and short-term intervention. General practitioners should be better educated about Fetal Alcohol Spectrum Disorders and have a clearer understanding of the Fetal Alcohol Spectrum Disorders care pathway.

Scoping review on the role of the family doctor in the prevention and care of patients with foetal alcohol spectrum disorder.

BACKGROUND: Foetal alcohol spectrum disorder (FASD) is the leading preventable cause of nongenetic mental disability. Given the patient care pathway, the General Practitioner (GP) is in the front line of prevention and identification of FASD. Acknowledging the importance of the prevalence of FASD, general practitioners are in the front line both for the detection and diagnosis of FASD and for the message of prevention to women of childbearing age as well as for the follow-up. OBJECTIVES: The main objective of the scoping review was to propose a reference for interventions that can be implemented by a GP with women of childbearing age, their partners and patients with FASD. The final aim of this review is to contribute to the improvement of knowledge and quality of care of patients with FASD. METHODS: A scoping review was performed using databases of peer-reviewed articles following PRISMA guidelines. The search strategy was based on the selection and consultation of articles on five digital resources. The advanced search of these publications was established using the keywords for different variations of FASD: "fetal alcohol syndrome," "fetal alcohol spectrum disorder," "general medicine," "primary care," "primary care"; searched in French and English. RESULTS: Twenty-three articles meeting the search criteria were selected. The interventions of GPs in the management of patients with FASD are multiple: prevention, identification, diagnosis, follow-up, education, and the role of coordinator for patients, their families, and pregnant women and their partners. FASD seems still underdiagnosed. CONCLUSION: The interventions of GPs in the management of patients with FASD are comprehensive: prevention, identification, diagnosis, follow-up, education, and the role of coordinator for patients, their families, and pregnant women and their partners. Prevention interventions would decrease the incidence of FASD, thereby reducing the incidence of mental retardation, developmental delays, and social, educational and legal issues. A further study with a cluster randomized trial with a group of primary care practitioners trained in screening for alcohol use during pregnancy would be useful to measure the impact of training on the alcohol use of women of childbearing age and on the clinical status of their children.

Actions to prevent and identify fetal alcohol spectrum disorders to be implemented in general practice: a consensus.

Introduction: Fetal alcohol exposure is the most common preventable cause of non-genetic intellectual disability. Fetal Alcohol Syndrome (FAS) is characterized by intellectual disability and distinctive facial features and affects 0.1% of live births, representing approximately 800 cases per year in France. Fetal Alcohol Spectrum Disorder (FASD) are 10 times more common than FAS, with an estimated 8,000 cases per year, and are associated with behavioral and social maladjustment in both children and adults, as well as various malformations. General practitioners play a key role in preventing and identifying FASD through their involvement in pregnancy and child monitoring. Methods: Qualitative study using the Delphi method. Items were developed from the literature and semi-structured interviews with field professionals and health institutions. A panel of multi-professional experts, mostly general practitioners, was recruited. Results: 24 initial actions were submitted to the experts. At the end of the first round, six actions reached a consensus and six were reformulated for the second round. At the end of the second round, three actions reached a consensus, for a total of 11 consensus actions. Four of these actions seem particularly relevant for rapid implementation, namely systematic proposal of pre-conceptional consultations for women planning pregnancy, systematic identification of environmental factors during child monitoring, systematic distribution of information on fetal alcohol exposure during pre-conception or early pregnancy, and the publication of a leaflet for general practitioners on the identification of children with FAS or FASD and the contact details of relevant associations. Conclusion: Prevention and identification of FASD can be improved through short and general training supports for general practitioners. Early screening of FASD is crucial for children, and should be maintained throughout their monitoring. This study could be used for communication and dissemination of information based on the consensus obtained.

The role of general practitioners in Reunion in detecting alcohol use in pregnant women and identifying fetal alcohol spectrum disorder: a qualitative study.

BACKGROUND: Fetal Alcohol Spectrum Disorder (FASD) is the leading cause of non-genetic intellectual disability and social maladjustment in children. International guidelines recommend abstinence from alcohol during pregnancy. Réunion is the most affected of all French regions with an estimated Fetal Alcohol Spectrum (FAS) prevalence of 1.2‰ births. General practitioners (GPs) are at the forefront of identifying patients with FASD. OBJECTIVE: To understand how GPs identify FASD. METHODS: Qualitative study using a grounded theory approach, through semi-structured face-to-face interviews with GPs. Interviews were conducted with the aim of reaching theoretical saturation. These were transcribed verbatim and then analyzed by four researchers to ensure triangulation of the data. RESULTS: GPs reported barriers to the identification of FASD: challenges in overcoming social taboos and paradoxical injunctions, the influence of limited knowledge and experience, non-specific and highly variable symptoms, ambiguous classification and method of diagnosis involving the mobilization of a multidisciplinary team and lengthy consultations. Conversely, they felt competent to identify neurodevelopmental disorders of any cause, but were concerned about the long waiting time to access specialized care. From the perspective of GPs, it is crucial to prioritize promotion and training aimed at improving the identification and coordination of care pathways for children diagnosed with neurodevelopmental disorders, such as FASD.

Experiences of adolescents using sexual health services on Reunion Island: protocol for a qualitative phenomenological study.

INTRODUCTION: Adolescence and early adulthood are often critical periods of sexual development. The discovery of sexual intercourse can lead to sexual risk-taking which may impact the incidence of sexually transmitted infections (STIs) and unwanted pregnancies. Despite available sexual health services on Reunion Island, sexual health indicators for adolescents are very poor showing a high number of teenage pregnancies and abortions, low use of contraception and an upsurge of STIs. In contrast, this French region is equipped with many services and resources that enable young adults to make informed sexual health choices. This study protocol describes the methodology to describe adolescent experiences of using sexual health services on Reunion Island. METHODS AND ANALYSIS: A monocentric descriptive qualitative study using a phenomenological approach will be conducted from December 2022 to August 2023 and will be based on face-to-face semistructured interviews with participants aged 15-19 years and residing on Reunion Island. Recruitment will be distributed at various educational institutions and sexual health centres and will be facilitated by the 'snowball' and 'word-of-mouth' effect. Data analysis will be independently carried out by three investigators to increase reliability. An interpretative phenomenological analysis will be performed. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the Hospital Center University De Bordeaux (CER-BDX-2022-55). Data generated do not fall within the field of biological or medical knowledge nor into the category of Research Involving the Human Person as defined in Articles L. 1121-1 and R. 1121-1 of the Public Health Code in France. All participants will receive information about the study in verbal and written forms and will give their oral consent before enrolment. Results will be published in a peer-reviewed journal as well as presented and disseminated at the Regional Health Agency of Reunion Island, conferences and in meetings with school directors.

Clinical and Epidemiological Changes in French Soldiers After Deployment: Impact of Doxycycline Malaria Prophylaxis on Body Weight.

BACKGROUND: Antibiotics are growth promotors used in animal farming. Doxycycline (DOXY) is a tetracycline antibiotic taken daily and continued 1 month after return to protect against malaria during travel and deployment in endemic areas. We evaluated DOXY impact on body weight in military international travelers. MATERIEL AND METHODS: A prospective cohort analysis was conducted in 2016-2018, recruiting 170 French soldiers before a 4-month assignment overseas. Many clinical data including anthropometric measures by an investigator were collected before and after deployment. Weight gain was defined by an increase of 2% from baseline. The study protocol was supported by the French Armed Forces Health Services and approved by the French ethics committee (IRB no. 2015-A01961-48, ref promoter 2015RC0). Written, informed consent was obtained with signature from each volunteer before inclusion. RESULTS: After deployment, 84 soldiers were followed up. Overall, 38/84 (45%) were deployed to Mali with DOXY malaria prophylaxis, and others were deployed to Iraq or Lebanon without malaria prophylaxis according to international recommendations. Body weight increased in 24/84 (30%), of whom 14/24 (58%) were exposed to DOXY. In bivariate analysis, DOXY had a positive but not significant effect on weight gain (P-value = .4). In the final logistic regression model (Fig. 3), weight gain after deployment positively correlated with an increase in waist circumference (odds ratio [OR] 1.23 with 95% CI [1.06-1.47]) suggesting fat gain; with sedentary work (OR 5.34; 95% CI [1.07-31.90]); and with probiotic intake (OR 5.27; 95% CI [1.51-20.40]). Weight impact of probiotics was more important when associated with DOXY intake (OR 6.86; 95% CI [1.52-38.1]; P-value = .016). CONCLUSIONS: Doxycycline (DOXY) malaria prophylaxis during several months did not cause significant weight gain in soldiers. Further studies are required in older and less sportive traveling populations, and to investigate a cumulative effect over time and recurrent DOXY exposure. Doxycycline (DOXY) may enhance other growth-promoting factors including fatty food, sedentariness, and strain-specific probiotics contained in fermented dairy products which are also used as growth promotors.

Attrition and social vulnerability during 2-year-long structured care in type 2 diabetes, the ERMIES randomized controlled trial.

BACKGROUND: Diabetes self-management education is exposed to attrition from services and structured ambulatory care. However, knowledge about factors related to attrition in educational programs remains limited. The context of social vulnerability due to low income may interfere. The aim of this study was to identify the sociodemographic, clinical, psychometric, and lifestyle factors associated with attrition from the ERMIES multicentre randomized parallel controlled trial (RCT) that was interrupted due to the combination of both slow inclusion and high attrition. METHODS: The ERMIES trial was performed from 2011 to 2016 on Reunion Island, which is characterized by a multicultural population and high social vulnerability. The original objective of the RCT was to test the efficacy of a2-year structured group self-management education in improving blood glucose in adult patients with nonrecent, insufficiently controlled type 2 diabetes. One hundred participants were randomized to intensive educational intervention maintained over two years (n = 51) versus only initial education (n = 49). Randomization was stratified on two factors: centres (five strata) and antidiabetic treatment (two strata: insulin-treated or not). Sociodemographic, clinical, health-care access and pathway, psychometric and lifestyle characteristics data were collected at baseline and used to assess determinants of attrition in a particular social context and vulnerability. Attrition and retention rates were measured at each visit during the study. Multiple correspondence analysis and Cox regression were performed to identify variables associated with attrition. RESULTS: The global attrition rate was 26% during the study, with no significant difference between the two arms of randomization (9 dropouts out of 51 patients in the intervention group and 17 out of 49 in the control group). Male gender, multiperson household, low household incomes (< 800 euros), probable depression and history of hospitalization or medical leave at inclusion were associated with a higher risk of attrition from the study in multivariate regression. CONCLUSIONS: Social context, vulnerability, and health care history were related to attrition in this 2-year longitudinal comparative study of structured care. Considering these potential determinants and biases is of importance in scaling up interventions aimed at the optimization of long-term care in type 2 diabetes mellitus.

Genome-Wide Characterization of a Highly Penetrant Form of Hyperlipoprotein(a)emia Associated With Genetically Elevated Cardiovascular Risk.

BACKGROUND: Lp(a) (lipoprotein [a]) is a highly atherogenic lipoprotein strongly associated with coronary artery disease (CAD). Lp(a) concentrations are chiefly determined genetically. Investigation of large pedigrees with extreme Lp(a) using modern whole-genome approaches may unravel the genetic determinants underpinning this pathological phenotype. METHODS: A large family characterized by high Lp(a) and increased CAD incidence was recruited by cascade screening. Plasma lipids, lipoproteins, and apolipoproteins concentrations, as well as the size of apo(a) isoforms, were determined enzymatically by high-resolution mass spectrometry and Western blot, respectively. Whole-exome sequencing was performed to search for rare defects in modifier genes. Genetic risk scores (GRS) for Lp(a) and CAD were calculated and their discriminative power was assessed. RESULTS: Seventeen individuals displayed extreme Lp(a) levels including 6 with CAD. Whole-exome sequencing showed no hint for genetic defects outside the LPA locus. The extreme Lp(a) phenotype segregated with the presence of a short apo(a) isoform containing 21 Kringle IV domains. This allele was characterized by the presence of three rare strongly Lp(a) increasing single nucleotide polymorphisms and a significantly increased load of oxidized phospholipids per Lp(a) particle. An Lp(a) GRS consisting of 48 single nucleotide polymorphisms that represent 2001 genome-wide significant LPA single nucleotide polymorphisms, efficiently captured the hyper-Lp(a) phenotype and discriminated affected and nonaffected individuals with great accuracy. The genome-wide GRS for CAD, encompassing 6.6 million single nucleotide polymorphisms, was very high for most family members (>97.5 percentile of the reference population), but this observation was no longer valid when the contribution of the LPA locus was omitted. CONCLUSIONS: High-Lp(a) phenotypes can be successfully captured using the Lp(a) GRS even among closely related family members. In hyper-Lp(a) individuals, LPA can be a major locus driving a very high CAD GRS. This underpins the large contribution of the LPA locus to the cardiovascular genetic risk in families.

Gut Microbiota in Military International Travelers with Doxycycline Malaria Prophylaxis: Towards the Risk of a Simpson Paradox in the Human Microbiome Field.

Dysbiosis, developed upon antibiotic administration, results in loss of diversity and shifts in the abundance of gut microbes. Doxycycline is a tetracycline antibiotic widely used for malaria prophylaxis in travelers. We prospectively studied changes in the fecal microbiota of 15 French soldiers after a 4-month mission to Mali with doxycycline malaria prophylaxis, compared to changes in the microbiota of 28 soldiers deployed to Iraq and Lebanon without doxycycline. Stool samples were collected with clinical data before and after missions, and 16S rRNA sequenced on MiSeq targeting the V3-V4 region. Doxycycline exposure resulted in increased alpha-biodiversity and no significant beta-dissimilarities. It led to expansion in Bacteroides, with a reduction in Bifidobacterium and Lactobacillus, as in the group deployed without doxycycline. Doxycycline did not alter the community structure and was specifically associated with a reduction in Escherichia and expression of Rothia. Differences in the microbiota existed at baseline between military units but not within the studied groups. This group-effect highlighted the risk of a Simpson paradox in microbiome studies.

Differential Impact According to Mission's Operational Intensity on Psychoactive Substance Use: A Retrospective Cohort of French Male Army Service Members.

BACKGROUND: Stressful deployments in combat areas are known to increase the risk of substance abuse in military personnel. OBJECTIVES: The aim of the study was to compare deployment on stressful, high-intensity missions (HIMs) to deployment on low-intensity missions (LIMs) in order to understand factors associated with substance use variations across the mission. METHODS: A retrospective cohort study based on a one-shot self-questionnaire was performed four months after their return on two samples of male French Army service members: one returning from an HIM and one from an LIM. The questionnaire focused on tobacco, alcohol, cannabis, cocaine, and psychoactive medication use at three times: before, during, and after the mission. RESULTS: During an HIM, the frequency of tobacco use increased, alcohol use remained stable - although 38% declared a decrease in consumption - and illicit drug use decreased. During an LIM, tobacco and alcohol use increased, cannabis use remained stable, and only cocaine and medication use decreased. After their return, use levels among both samples reverted to values similar to those reported before the mission, except for a decrease in tobacco use observed at return from an HIM. The main factors perceived as related to variations were stress in an HIM and low cost in an LIM. Conclusions/importance: The study suggests a differential impact of deployment on substance use according to the operational intensity of the mission. Variations in use are predominant during the mission with a washout effect after returning home.

Sexual health in the French military: a multidimensional and gendered perspective.

BACKGROUND: Sexual health in the military comprises a range of concerns including sexually transmitted infections (STI), unintended pregnancy, sexual violence and sexual dysfunction. This study aims to estimate the prevalence of sexual health concerns by gender in the French military and compare these prevalences to estimates in the general population. METHODS: COSEMIL, the first sexual health survey in the French military comprises a probability sample of 1500 military personnel. Chi-square tests were used to compare lifetime abortion, STIs and sexual assault, and recent sexual dysfunction and sexual satisfaction by gender and explore the association between these indicators and current sexual risk (condom use at last intercourse). RESULTS: Women were more likely than men to declare negative sexual health outcomes, with the greatest difference related to sexual assault (24.3% versus 5.1% of males, p < 0.001) and sexual dysfunction hindering sexuality (15.2% of females versus 5.3% of males, p < 0.001). Women were also twice as likely to report ever having an STI (6.7% versus 3.4%, p = 0.03). Comparison with the French general population indicates lower percentages of STIs among military men (2.9% versus 4.9%) and higher percentages of abortion (17.6% versus 14.3%) forced sex (10.6% versus 7.4%) and sexual dysfunction (14.2% versus 9.3%) among military women. CONCLUSION: These results highlight gendered pattern of sexual health in the French military with women suffering greater sexual risks than men. Military health services should include women's health services to address the sexual and reproductive health gender gap.

Factor associated with risky sexual behaviors among the French general population.

Background: Despite prevention programs, a rising incidence of sexually transmitted infections is currently reported in France. Aims: Research factors associated with risky sexual behaviors (RSBs) among the French population. Methods: Subjects aged 15-54 years from the French national survey 'Baromètre santé 2010' were included (n = 16 598). RSB was defined as having multiple partners or failure to use condom at first intercourse with a new partner over past 12 months. Factors associated were identified using one logistic regression by gender. Results: The overall RSB prevalence was 9.5%, being higher among men (P < 0.001). Factors associated with RSB for both genders were young age (OR = 1.5), single status (men: OR = 7.1; women: OR = 6.4), homosexual relations (men: OR = 2.0; women: OR = 3.2), low incomes (men: OR = 1.5; women: OR = 1.4), use of cannabis (men: OR = 1.4; women: OR = 3.0). Men-specific factors were history of STI (OR = 2.5) and alcohol drunkenness (OR = 2.2), and women-specific factors history of suicide attempt (OR = 1.6) and history of sexual assault (OR = 1.6). Conclusions: Confirming most of known determinants of RSB, this study also identified some specific risky patterns for whom preventive actions can be developed: multiusers of psychoactive substances, people living with low incomes, women having sex with women or presenting history of psychological vulnerability (suicide attempts, sexually harassed).

Do alcohol-based hand rubs reduce the incidence of acute diarrhea during military deployments? A prospective randomized trial.

BACKGROUND: Acute diarrhea remains a public health concern in armed forces deployed in tropical areas where access to water and soap is limited. This study aims to assess the effectiveness of alcohol-based hand rubs (ABHR) on incidence of diarrhea in poor hygiene conditions. METHOD: A prospective randomized trial was conducted between November 2014 and January 2015 among French military troops deployed in Africa to compare a group of soldiers receiving usual hand hygiene recommendations (control group), to a group of soldiers who received ABHR in addition to usual hand hygiene recommendations (intervention group). Data on diarrhea and hygiene behaviors were collected using self-questionnaires. The incidence rate of diarrhea episodes in groups was compared. RESULTS: Participation rate was 59% (236/400). The proportion of individuals who used ABHR was 97% in the intervention group and 62% in the control group. The overall incidence rate of diarrheal episodes was observed to be in the region of 60 per 100 persons-month without any significant difference between groups after adjustment on confounding factors (p = 0.93). Handwashing with soap was used on average 4 times a day in the control group and twice a day in the intervention group (p = 0.93). It was the only significant protective factor for diarrhea (p < 10-3). CONCLUSION: Our results support that supplying soap and good quality water should be a priority on the field.

What's the hospitalisation's impact on background treatments of patients over 65 years.

As our population aging increases, it requires a particular attention from the health system. Indeed, elderly are often frail, with several diseases and presenting high risk of adverse drug accident. Prescribing appropriately to the elderly has become an important matter. Hospitalization and consultation with the general practitioner are key moments for drug prescription. However, their real impact on background treatments of this population has been barely evaluated. A retrospective descriptive study was conducted with 300 patients over 65 years old, hospitalized at the Laveran military hospital in Marseille. Treatment modifications, consecutive to hospitalization and to the first consultation with the general practitioner, were identified and analyzed. We found an average prescription of 5.93 drugs in prehospital period and 66% of the patients with polypharmacy. Drugs for cardiovascular system were the most prescribed and the most modified. Hospitalization generated a rate of modification by prescription of 28.5% and the consultation with the general practitioner following this hospitalization led to further change in 48% of cases. Beside the important prevalence of patients with polypharmacy, this study shows that hospitalization entails a significant change in background treatments in that population at risk. Therefore, it is important to have a consensus in the re-evaluation of these treatments, in order to prevent the iatrogenic risk.

Post-Traumatic Stress Disorder among French Armed Forces Members in Afghanistan: A New Approach.

During the 20th century, the management of war-related psychological trauma shifted from neurology to psychiatry. After September 11, 2001, the French forces participated in a multinational force deployed in Afghanistan to fight against terrorism. Post-traumatic stress disorder (PTSD) became a priority. We report the daily work of the psychiatrists involved in this mission and the organization developed to psychologically support wounded military personnel. The doctrine of early intervention psychiatrization and the technique of collective debriefing are the key points of this procedure. The psychiatrist is also responsible for the healthcare community, particularly vulnerable when confronted with severe ballistic injuries. One aim of this organization is also to screen PTSD in soldiers returning from Afghanistan. The military general practitioner is a pivotal point of this procedure built to detect PTSD, anxiety, depressive reaction and behavioral problems. The French health service has developed a genuine care strategy aimed at identifying patients, accompanying them in the formalities for recognition and compensation, and offering them treatment locally by arranging clinical psychology consultations near their home.

Factors associated with malaria chemoprophylaxis compliance among French service members deployed in Central African Republic.

BACKGROUND: Malaria is a public health concern in the French armed forces, with 400-800 cases reported every year and three deaths in the past 2 years. However, lack of chemoprophylaxis (CP) compliance is often reported among service members. The aim of this study was to explore factors associated with CP compliance. METHODS: A retrospective study (1296 service members) was carried out among troops deployed in Central African Republic. Determinants of CP were collected by self-questionnaire. Socio-demographic variables, behavioural characteristics, belief variables, operational determinants such as troops in contact (TIC) and number of nights worked per week and peer-to-peer reinforcement were studied. Relationships between covariates and compliance were explored using logistic regressions (outcome: compliance as a dummy variable). RESULTS: Chemoprophylaxis compliance was associated with other individual preventive measures against mosquito bites (bed net use, OR (odds ratio) = 1.41 (95% CI [1.08-1.84]), and insecticide on clothing, OR = 1.90 ([1.43-2.51]) and malaria-related behaviours (taking chemoprophylaxis at the same time every day, OR = 2.37 ([1.17-4.78]) and taking chemoprophylaxis with food, OR = 1.45 ([1.11-1.89])). High perceived risk of contracting malaria, OR = 1.59 ([1.02-2.50]), positive perception of CP effectiveness, OR = 1.62 ([1.09-2.40]) and the practice of peer-to-peer reinforcement, OR = 1.38 ([1.05-1.82]) were also associated with better compliance. No association was found with TIC and number of nights worked. CONCLUSIONS: This study, which shows a positive relationship between peer-to-peer reinforcement and CP compliance, also suggests the existence of two main personality profiles among service members: those who seek risks and those who are health-conscious. Health education should be expanded beyond knowledge, know-how and motivational factors by using a comprehensive approach based on identification of health determinants, development of psychosocial skills and peer-to-peer reinforcement.

Relationships between substance initiation sequence and further substance use: A French nationwide retrospective study.

The Gateway theory (GT) proposes that tobacco or alcohol use lead to cannabis use, which can itself be followed by other illicit drugs (OID) onset. Aim of this study was to evaluate if the order of initiation sequence could influence further substance use. Data from a 2010 population-based survey were used (22,774 subjects aged 15-64). Using reported ages at initiations, 7 sequences were identified: initiation of tobacco only (T), cannabis or OID only, tobacco followed by cannabis (T-C), cannabis followed by tobacco (C-T), alternative 2-substance sequences, gateway sequence (T-C-OID) and 3-substance alternative sequences. Logistics regressions were performed to study the impact of sequence on further use (tobacco, alcohol, cannabis and OID), and substance use disorders (SUD) (tobacco, alcohol and cannabis). The most observed sequences were T (45.5%), T-C (20.5%), C-T (5.1%) and T-C-OID (3.5%). Further use and SUD likelihoods, whatever the substance considered, increased with the number of substances previously initiated. However, for a same number of substances initiated, current use and SUD likelihoods did not significantly vary according to sequence. Polysubstance initiation appears as a better predictor of further use and SUD than the initiation sequence, questioning the GT and being more in line with a common liability to substance use.

Variations in Cannabis Use Level and Correlates in Opiate-Users on Methadone Maintenance Treatment: A French Prospective Study.

INTRODUCTION: Concurrent cannabis use is very frequent among opioid users on methadone maintenance treatment (MMT), which could reflect a coping strategy during MMT. The aims of this study were to describe variations in cannabis use and to explore whether MMT could modify the patterns of cannabis use correlates. METHODS: The sample included 188 opioid-dependent individuals who initiated MMT and were prospectively followed for 12 months. Cannabis use was monitored at enrollment and at months 3, 6 and 12. The relationships between cannabis use level (non-daily use and daily use vs. no use in the previous month) and its determinants (socioeconomic factors, substance use characteristics and mental health) were explored using mixed multinomial logistic regressions. RESULTS: No significant variation trend in cannabis use levels was observed during the follow-up period among the 188 subjects analyzed (p=0.85). After adjustment for socio-demographic factors, opioid use was associated with both non-daily (OR=3.11, p=0.01) and daily cannabis use (OR=2.58, p=0.04). Moreover the number of health problems reported was associated with daily cannabis use (OR=1.12 per 1-problem increase, p=0.004). The factors associated with cannabis use appeared similar before and after starting treatment (no significant interaction observed between MMT and any factor). CONCLUSIONS: Cannabis use during MMT more likely reflects pre-existing common liability to substance use or self-medication practices towards health problems than a behavior aimed at managing problems with MMT. With recent research suggesting an interaction between cannabinoid and opioid systems, the benefit of cannabis-based pharmacotherapies during MMT should be further explored in addiction research.

Specific management of post-chikungunya rheumatic disorders: a retrospective study of 159 cases in Reunion Island from 2006-2012.

BACKGROUND: Since 2003, the tropical arthritogenic chikungunya (CHIK) virus has become an increasingly medical and economic burden in affected areas as it can often result in long-term disabilities. The clinical spectrum of post-CHIK (pCHIK) rheumatic disorders is wide. Evidence-based recommendations are needed to help physicians manage the treatment of afflicted patients. PATIENTS AND METHODS: We conducted a 6-year case series retrospective study in Reunion Island of patients referred to a rheumatologist due to continuous rheumatic or musculoskeletal pains that persisted following CHIK infection. These various disorders were documented in terms of their clinical and therapeutic courses. Post-CHIK de novo chronic inflammatory rheumatisms (CIRs) were identified according to validated criteria. RESULTS: We reviewed 159 patient medical files. Ninety-four patients (59%) who were free of any articular disorder prior to CHIK met the CIR criteria: rheumatoid arthritis (n=40), spondyloarthritis (n=33), undifferentiated polyarthritis (n=21). Bone lesions detectable by radiography occurred in half of the patients (median time: 3.5 years pCHIK). A positive therapeutic response was achieved in 54 out of the 72 patients (75%) who were treated with methotrexate (MTX). Twelve out of the 92 patients (13%) received immunomodulatory biologic agents due to failure of contra-indication of MTX treatment. Other patients mainly presented with mechanical shoulder or knee disorders, bilateral distal polyarthralgia that was frequently associated with oedema at the extremities and tunnel syndromes. These pCHIK musculoskeletal disorders (MSDs) were managed with pain-killers, local and/or general anti-inflammatory drugs, and physiotherapy. CONCLUSION: Rheumatologists in Reunion Island managed CHIK rheumatic disorders in a pragmatic manner following the outbreak in 2006. This retrospective study describes the common mechanical and inflammatory pCHIK disorders. We provide a diagnostic and therapeutic algorithm to help physicians deal with chronic patients, and to limit both functional and economic impacts. The therapeutic indication of MTX in pCHIK CIR could be approved in future efficacy trials.
