ABSTRACT
Uncertainty estimations through approximate Bayesian inference provide interesting insights to deep neural networks' behavior. In unsupervised learning tasks, where expert labels are unavailable, it becomes ever more important to critique the model through uncertainties. This paper presents a proof-of-concept for generalizing the aleatoric and epistemic uncertainties in unsupervised MR-CT synthesis of scoliotic spines. A novel adaptation of the cycle-consistency constraint in CycleGAN is proposed such that the model predicts the aleatoric uncertainty maps in addition to the standard volume-to-volume translation between Magnetic Resonance (MR) and Computed Tomography (CT) data. Ablation experiments were performed to understand uncertainty estimation as an implicit regularizer and a measure of the model's confidence. The aleatoric uncertainty helps in distinguishing between the bone and soft-tissue regions in CT and MR data during translation, while the epistemic uncertainty provides interpretable information to the user for downstream tasks.
ABSTRACT
Freehand 3D ultrasound imaging is emerging as a promising modality for regular spine exams due to its non-invasiveness and affordability. The laminae landmarks play a critical role in depicting the 3D shape of the spine. However, the extraction of the 3D lamina curves from transverse ultrasound sequences presents a challenging task, primarily attributed to the presence of diverse contrast variations, imaging artifacts, the complex surface of vertebral bones, and the difficulties associated with probe manipulation. This paper proposes Sequential Localization Recurrent Convolutional Networks (SL-RCN), a novel deep learning model that takes the contextual relationships into account and embeds the transformation matrix feature as a 3D knowledge base to enhance accurate ultrasound sequence analysis. The assessment involved the analysis of 3D ultrasound sequences obtained from 10 healthy adult human participants, covering both the lumbar and thoracic regions. The performance of SL-RCN is evaluated through 7-fold cross-validation, employing the leave-one-participant-out strategy. The validity of the AI model training is assessed on test data from 3 participants. Normalized Discrete Fréchet Distance (NDFD) is employed as the main metric to evaluate the disparity of the extracted 3D lamina curves. In contrast to our previous 2D image analysis method, SL-RCN generates reduced left/right mean distance errors from 1.62/1.63mm to 1.41/1.40mm, and NDFDs from 0.5910/0.6389 to 0.4276/0.4567. The increase in the mean NDFD value from 7-fold cross-validation to the test-data experiment is less than 0.05. The experiments demonstrate the SL-RCN's capability in extracting accurate paired smooth lamina landmark curves.
ABSTRACT
As a daily physiological mechanism in bone, microdamage accumulation dissipates energy and helps to prevent fractures. However, excessive damage accumulation might bring adverse effects to bone mechanical properties, which is especially problematic among the osteoporotic and osteopenic patients treated by bisphosphonates. Some pre-clinical studies in the literature applied forelimb loading models to produce well-controlled microdamage in cortical bone. Ovariectomized animals were also extensively studied to assimilate human conditions of estrogen-related bone loss. In the present study, we combined both experimental models to investigate microdamage accumulation in the context of osteopenia and zoledronate treatment. Three-month-old normal and ovariectomized rats treated by saline or zoledronate underwent controlled compressive loading on their right forelimb to create in vivo microdamage, which was then quantified by barium sulfate contrast-enhanced micro-CT imaging. Weekly in vivo micro-CT scans were taken to evaluate bone (re)modeling and to capture microstructural changes over time. After sacrifice, three-point-bending tests were performed to assess bone mechanical properties. Results show that the zoledronate treatment can reduce cortical microdamage accumulation in ovariectomized rats, which might be explained by the enhancement of several bone structural properties such as ultimate force, yield force, cortical bone area and volume. The rats showed increased bone formation volume and surface after the generation of microdamage, especially for the normal and the ovariectomized groups. Woven bone formation was also observed in loaded ulnae, which was most significant in ovariectomized rats. Although all the rats showed strong correlations between periosteal bone formation and microdamage accumulation, the correlation levels were lower for the zoledronate-treated groups, potentially because of their lower levels of microdamage. The present study provides insights to further investigations of pharmaceutical treatments for osteoporosis and osteopenia. The same experimental concept can be applied in future studies on microdamage and drug testing.

PURPOSE: Studies in the United States, Canada, Belgium, and Switzerland showed that the majority of health problems are managed within primary health care; however, the ecology of French medical care has not yet been described. METHODS: Nationwide, population-based, cross sectional study. In 2018, we included data from 576,125 beneficiaries from the General Sample of Beneficiaries database. We analysed the reimbursement of consultations with (i) a general practitioner (GP), (ii) an outpatient doctor other than a GP, (iii) a doctor from a university or non-university hospital; and the reimbursement of (iv) hospitalization in a private establishment, (v) general hospital, and (vi) university hospital. For each criterion, we calculated the average monthly number of reimbursements reported on 1,000 beneficiaries. For categorical variables, we used the χ2 test, and to compare means we used the z test. All tests were 2-tailed with a P-valueâ <â 5% considered significant. RESULTS: Each month, on average, 454 (out of 1,000) beneficiaries received at least 1 reimbursement, 235 consulted a GP, 74 consulted other outpatient doctors in ambulatory care and 24 in a hospital, 13 were hospitalized in a public non-university hospital and 10 in the private sector, and 5 were admitted to a university hospital. Independently of age, people consulted GPs twice as much as other specialists. The 13-25-year-old group consulted the least. Women consulted more than men. Individuals covered by complementary universal health insurance had more care. CONCLUSIONS: Our study on reimbursement data confirmed that, like in other countries, in France the majority of health problems are managed within primary health care.

PURPOSE: The acquisition of good quality ultrasound (US) images requires good acoustic coupling between the ultrasound probe and the patient's skin. In practice, this good coupling is achieved by the operator applying a force to the skin through the probe. This force induces a deformation of the tissues underlying the probe. The distorted images deteriorate the quality of the reconstructed 3D US image. METHODS: In this work, we propose two methods to correct these deformations. These methods are based on the construction of a biomechanical model to predict the mechanical behavior of the imaged soft tissues. The originality of the methods is that they do not use external information (force or position value from sensors, or elasticity value from the literature). The model is parameterized thanks to the information contained in the image. This is allowed thanks to the optimization of two key parameters for the model which are the indentation d and the elasticity ratio α. RESULTS: The validation is performed on real images acquired on a gelatin-based phantom using an ultrasound probe inducing an increasing vertical indentation using a step motor. The results showed a good correction of the two methods for indentations less than 4 mm. For larger indentations, one of the two methods (guided by the similarity score) provides a better quality of correction, presenting a Euclidean distance between the contours of the reference image and the corrected image of 0.71 mm. CONCLUSION: The proposed methods ensured the correction of the deformed images induced by a linear probe pressure without using any information coming from sensors (force or position), or generic information about the mechanical parameters. The corrected images can be used to obtain a corrected 3D US image.

Background: Cannabis use by physicians can be detrimental for them and their patients. We conducted a systematic review and meta-analysis on the prevalence of cannabis use by medical doctors (MDs)/students. Method: PubMed, Cochrane, Embase, PsycInfo and ScienceDirect were searched for studies reporting cannabis use in MDs/students. For each frequency of use (lifetime/past year/past month/daily), we stratified a random effect meta-analysis depending on specialties, education level, continents, and periods of time, which were further compared using meta-regressions. Results: We included 54 studies with a total of 42,936 MDs/students: 20,267 MDs, 20,063 medical students, and 1976 residents. Overall, 37% had used cannabis at least once over their lifetime, 14% over the past year, 8% over the past month and 1.1 per thousand (‱) had a daily use. Medical students had a greater cannabis use than MDs over their lifetime (38% vs. 35%, p < 0.001), the past year (24% vs. 5%, p < 0.001), and the past month (10% vs. 2%, p < 0.05), without significance for daily use (0.5% vs. 0.05%, NS). Insufficient data precluded comparisons among medical specialties. MDs/students from Asian countries seemed to have the lowest cannabis use: 16% over their lifetime, 10% in the past year, 1% in the past month, and 0.4% daily. Regarding periods of time, cannabis use seems to follow a U-shape, with a high use before 1990, followed by a decrease between 1990 and 2005, and a rebound after 2005. Younger and male MDs/students had the highest cannabis use. Conclusions: If more than a third of MDs tried cannabis at least once in their lifetime, this means its daily use is low but not uncommon (1.1‱). Medical students are the biggest cannabis users. Despite being common worldwide, cannabis use is predominant in the West, with a rebound since 2005 making salient those public health interventions during the early stage of medical studies.
ABSTRACT
BACKGROUND: The advent of miniature, easy-to-use and accessible multimedia products is leading to screen exposure that begins in early childhood. Overexposure in preschool may lead to adverse effects. The main objective of this study was to determine the average daily time (ADT) spent by children under 6 years of age, followed in general practice, in front of television or interactive screens. METHODS: A cross-sectional survey was conducted in the Auvergne-Rhône-Alpes region among randomly selected General Practitioners (GPs). The average daily screen time (ADST), regardless of the type of device (TVs, computers, tablets, smartphones, video game consoles), of the included children aged 0 to 2 years and 2 to 5 years was calculated from a self-questionnaire completed by the parents. A multivariate Poisson regression model was performed to analyse daily screen time, adjusted by factors selected on their clinical relevance and statistical significance. RESULTS: The 26 participating GPs included 486 parents. They reported an ADST of 26 (± 44) minutes on weekdays and 30 (± 46) minutes on weekends for children under 2 years of age. For children over 2 years of age, the ADST was 66 (± 82) minutes on weekdays and 103 (±91) minutes on weekends. There was an association between the children's average screen time and certain sociodemographic and environmental factors. Children whose parents had higher levels of education, those living in a family without TV screens or those who were well informed about the possible adverse health consequences of overuse of screens had lower average screen time. On the other hand, children of parents who spent more than 2 hours a day in front of screens, were more exposed. CONCLUSIONS: In our survey, the ADST of children under 6 years of age followed in general practice was higher than the current recommendations. GPs can warn parents of preschool children of the effects of overexposure to screens, particularly parents of at-risk children.

Physical exercise is important for musculoskeletal development during puberty, which builds bone mass foundation for later in life. However, strenuous levels of training might bring adverse effects to bone health, reducing longitudinal bone growth. Animal models with various levels of physical exercise were largely used to provide knowledge to clinical settings. Experiments from our previous studies applied different levels of mechanical loading on rat tibia during puberty accompanied by weekly in vivo micro-CT scans. In the present article, we apply 3D image registration-based methods to retrospectively analyze part of the previously acquired micro-CT data. Longitudinal bone growth, growth plate thickness, and cortical bone (re)modeling were evaluated from rats' age of 28-77 days. Our results show that impact loading inhibited proximal bone growth throughout puberty. We hypothesize that impact loading might bring different growth alterations to the distal and proximal growth plates. High impact loading might lead to pathological consequence of osteochondrosis and catch-up growth due to growth inhibition. Impact loading also increased cortical bone (re)modeling before and after the peak proximal bone growth period of young rats, of which the latter case might be caused by the shift from modeling to remodeling as the dominant activity toward the end of rat puberty. We confirm that the tibial endosteum is more mechano-sensitive than the periosteum in response to mechanical loading. To our knowledge, this is the first study to follow up bone growth and bone (re)modeling of young rats throughout the entire puberty with a weekly time interval.

BACKGROUND: The Congress of the National College of Academic General Practitioners took place in France in June 2021. In total, 1300 participants were registered, provoking concerns about the risk of COVID-19 contamination. OBJECTIVES: The study objective was to report participation in the first French face-to-face medical congress after restrictions due to COVID-19 and whether it resulted in COVID-19 contamination. METHODS: We performed two web-based surveys of respectively 46 and 33 questions. The first questionnaire was sent to all congress participants during the congress (and to a panel of non-participants) and investigated demographic characteristics, medical conditions, behaviours related to COVID-19 contamination risk, and the interest of face-to-face congress as compared to virtual congress. Two weeks after the congress, a questionnaire was addressed to the same population and to university General Practice departments to identify incident COVID-19 cases among participants. RESULTS: A total of 1001 general practitioners and residents completed the first questionnaire; 752 participated in the congress. The respondents were mainly women (61.3%), with a mean age of 35 (SD 10) years, 96.2% had been vaccinated against SARS-CoV-2, and 11.4% considered themselves at risk for a severe form of COVID-19 for medical reasons. Concerning the interest in attending the congress face-to-face, mean score was 9 over 10 (SD 1.5). No case of COVID-19 was reported among participants according to the second questionnaire (449 respondents). CONCLUSION: During a world pandemic, even participants considering themselves at risk came to a medical congress, highlighting the networking and social aspects of a face-to-face congress.

OBJECTIVE: To estimate the prevalence of the paracetamol use for a reason other than pain (qualitative misuse) during the last 12 months in patients consulting their general practitioner, as well as the reasons for this misuse. METHODS: Descriptive cross-sectional analysis, with gender weighting to estimate the prevalence of paracetamol misuse. RESULTS: In total, data from 209 patients were included in the analysis. Among them, 11 patients declared having taken paracetamol for a reason other than pain, i.e., a gender-weighted prevalence of 5.7% (95% CI: 3.0 to 10.4). Nearly two-thirds of these patients said they had done it to feel better. CONCLUSIONS: The paracetamol misuse is rare but real in general practice. Further studies are needed to better understand it, especially qualitative studies.
ABSTRACT
Analgesic opioid (AO) misuse by patients ranges from 0% to 50%. General practitioners are the first prescribers of AO. Our objective was to validate the Prescription Opioid Misuse Index (POMI) in primary care. We conducted a psychometric study in patients with chronic pain who had been taking AOs for at least 3 months and were followed in general practice. Patients responded to the POMI at inclusion and after 2 weeks. The reference used was the DSM-V. Sixty-nine GPs included 160 patients (87 women, 54.4%), mean age 56.4 ± 15.2 years. The total POMI score was 1.50 ± 1.27, and 73/160 (45.6.0%) had a score ≥ 2 (misuse threshold). Internal validity was measured with the Kuder-Richardson coefficient, which was 0.44. Correlations between each item and the total score ranged from 0.06 to 0.35. Test-retest reliability was determined from 145 patients: Lin's concordance coefficient was 0.57 [0.46, 0.68]. Correlation with the DSM-V (Spearman's coefficient) was 0.52. The POMI does not have sufficient psychometric properties to be recommended as a tool to identify the misuse of AOs in primary care. This study clearly showed that there is a need to create a monitoring tool specific to primary care.

The world is still in the grip of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, with putative psychological consequences for healthcare workers (HCWs). Exploring the prevalence of post-traumatic stress disorder (PTSD) during the first SARS-CoV-1 epidemic in 2003 may inform us of the long-term effects of the actual pandemic, as well as putative influencing factors such as contact with the virus, time effects, or the importance of some sociodemographic data. This information may help us develop efficient preventive strategies. Therefore, we conducted a systematic review and meta-analysis on the prevalence of PTSD in HCWs following the SARS-CoV-1 in 2003. PubMed, Embase, Google Scholar, Psychinfo, and Web of Science were searched until September 2022. Random-effects meta-analyses were stratified by the time of follow-up. We included 14 studies: 4842 HCWs (32.0 years old, 84% women). The overall prevalence of PTSD was 14% (95CI 10 to 17%). The prevalence of PTSD was 16% (8 to 24%) during the epidemic, 19% (16 to 22%) within 6 months after the epidemic, and 8% (4 to 13%) more than one year after the end of the epidemic. The longest follow-up was three years after the epidemic, with 10% of HCWs with PTSD. Nevertheless, the prevalence of PTSD was significantly lower more than one year after the end of the epidemic than the first six months after the epidemic (Coefficient -10.4, 95CI -17.6 to -3.2, p = 0.007). In conclusion, the prevalence of PTSD in HCWs was high during the first epidemic of SARS-CoV in 2003 and remained high in the long term. The lessons from the SARS-CoV-1 epidemic may help prevent a wave of PTSD following the latest COVID-19 pandemic.

AIMS: General practitioners (GPs), who are the most frequently consulted health professionals by adolescents, play a key role in screening for psychoactive substance (PAS) use. The purpose of our study was to determine the barriers and expectations of adolescents regarding the identification and management of their PAS use by their general practitioner. METHODS: Descriptive, cross-sectional study of a population of adolescents aged 12 to 17 years, followed up in general practice in France. Adolescents were recruited from general practice offices by open-access questionnaires. An opaque box was provided to ensure the anonymity of the adolescents. RESULTS: A total of 277 adolescents were included: 155 girls, mean age 14.5 ± 1.7 years, 113 adolescents (41%) had used a PAS at least once in the past 12 months. Alcohol was the most used PAS, followed by tobacco and cannabis. Three groups were identified: the nonusers group (n = 134); the group of moderate users (n = 71); the group of users at risk of substance abuse or misusing (n = 38). Regardless of group, adolescents felt that their GP was attentive, responsive, competent, understanding, and took the time to ask the appropriate questions in their role. The at-risk group was less confident and less comfortable, and they felt more judged and more afraid of the GP telling their parents. Despite this, the at-risk group was the most willing to talk to their GP about their PAS. Almost half of the adolescents surveyed found it useful to use a questionnaire to discuss PAS. CONCLUSIONS: Reminding each consultation of the principles of the relationship of trust and confidentiality while maintaining an empathetic attitude would make it easier for GPs to remove adolescents' inhibitions about communicating about their PAS use.

BACKGROUND: Socioeconomic deprivation (SED) is a risk factor for complications during pregnancy and childbirth, the impact of which has been studied poorly in rural areas. AIMS: To explore the perceptions and behaviour of women living in SED in a rural area with regard to their pregnancy follow-up. METHODS: A qualitative study using semi-structured individual interviews was carried out in a rural area in central France. To participate, the women had to have an Evaluation of Deprivation and Inequalities in Health Examination Centres deprivation score ≥ 30.17, be living in a rural area and have given birth during the month before the interview. The interviews were analysed using a thematic approach inspired by grounded theory. RESULTS: Seventeen women were interviewed. The difficulties of life in a rural area were linked to geographical remoteness, travel costs, lack of public services, inadequacy of nearby healthcare and social isolation. In all cases, pregnancy was an additional difficulty. The adaptive capability was related to the presence of an efficient family and social network. Most of the time, any increase in the limitations exceeded the ability to adapt and affected the medical follow-up of the pregnancy, although follow-up appointments were rarely abandoned altogether. Perceptions of birth preparation and parenting sessions were often limited to advice on pain management. Due to their affiliation with their rural area or their choice of lifestyle, the women complained only minimally. CONCLUSION: Women often minimize any limitations and implement adaptive techniques that make identification by social and medical services more difficult. PATIENT OR PUBLIC CONTRIBUTION: Eighteen women in SED were contacted by Childhood Medical Protection, midwives and general practitioners practising in rural areas. One woman declined participation and seventeen were interviewed.

INTRODUCTION: The aim of this systematic review was to assess the effectiveness of brief interventions realized in primary care in reducing cannabis use for adolescents and emerging adults. METHODS: PubMed, CINAHL, Embase, PsycInfo, and Central (Cochrane Library) were searched until December 2020. Randomized controlled trials conducted in primary care, concerning in-person brief interventions for non-medical cannabis users aged from 12 to 25 years old were eligible for inclusion. Brief interventions had to last 30 min or less. Patients with comorbid mental health disorder or very specific populations were not included. RESULTS: One thousand eighty hundred and fifty-five studies were identified through database searching; only 8 studies involving 2,199 patients were included for qualitative synthesis after double reading and data extraction. Randomized controlled trials selected were heterogeneous regarding screening tools, initial levels of cannabis use and cannabis outcomes measures. Brief interventions were all based on motivational interviewing techniques or personalized feedback. Seven studies consisted in a single session of brief intervention. Six studies involved also other substance users. No significant reduction of cannabis use after brief intervention was found for most studies, especially in the long term. A trend of decreased cannabis consequences, such as negative psychosocial repercussions, perception of cannabis use by peers, or driving under the influence of cannabis, was reported. CONCLUSION: The current state of knowledge does not allow us to say that the brief intervention is effective in reducing cannabis use among adolescents in primary care. We found a mild positive effect on cannabis consequences after brief intervention. Mixed qualitative and quantitative studies are need to better evaluate the impact of brief intervention and his faisability.

BACKGROUND: We conducted a systematic review and meta-analysis to assess the effects of lifestyle intervention on telomere length (TL). METHOD: Four databases were searched for studies reporting TL in leukocytes, before and after a lifestyle intervention. We computed random-effects meta-analysis on TL within intervention and control group after versus before intervention, and on changes in TL between groups. Sensitivity analyses and Meta-regression were conducted. RESULTS: We included 20 studies in the systematic review (2995 participants, mean 50.3 years old, 77% women, 2045 following an intervention and 950 controls) and 19 in the meta-analysis. TL were similar at baseline between intervention and control groups. The physical activity ± diet group had an increase in TL (Effect size 0.17, 95%CI 0.03-0.31, p = 0.020) using changes within the intervention group, whereas TL shortened in the control group (-0.32, -0.61 to -0.02, p = 0.037). TL was longer in the physical activity ± diet intervention group (0.24, 0.08-0.40, p = 0.004) compared to controls after the intervention. Sensitivity analysis gave similar results. Meta-regressions demonstrated that combining strength and endurance exercise increased TL more than endurance alone or strength alone. CONCLUSION: A lifestyle intervention with physical activity ± diet can increase telomere length, independently of population characteristics or baseline TL.

PURPOSE: The Prescription Opioid Misuse Index scale (POMI) is a brief questionnaire used to assess opioid prescription misuse. In view of the increase in the prescription of opioid analgesics for chronic noncancer pain (CNCP), this tool is particularly useful during medical consultations to screen opioid misuse in patients using opioids. We sought to generate and validate a French-European translation of the POMI. METHODS: We conducted an observational, longitudinal, and multicenter psychometric study with crosscultural validation. All adult CNCP patients who were treated with opioids for at least three months, were followed in pain clinics, and spoke French were eligible. From September 2015 to November 2017, we included 163 patients and analyzed 154. We performed a pretest on a sample of representative patients to evaluate acceptability and understanding of translation. Study patients completed the POMI scale at a pain clinic (test phase), and we assessed test-retest reliability after two to four weeks by a second completion of the POMI scale at home by patients (retest phase). We subsequently explored psychometric properties of the POMI (acceptability, internal consistency, reproducibility, and external validity). RESULTS: Due to poor internal consistency and reproducibility, items 4, 7, and 8 of the original POMI scale were removed, and we proposed a five-question French-European version (POMI-5F). The internal consistency of POMI-5F was good (Cronbach's α = 0.71), as was test-retest reliability (r = 0.65 [0.55-0.67]). The external validity of POMI-5F, compared with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, was moderate but significant (r = 0.45; P < 0.001). The optimal POMI-5F cut-off score to indicate misuse was 2/5 (sensitivity = 0.95 and specificity = 0.54). CONCLUSION: We generated and validated a French-European translation of the POMI scale, POMI-5F, for use by French researchers and physicians to identify opioid misuse in CNCP patients.
RéSUMé: OBJECTIF: L'échelle Prescription Opioid Misuse Index (POMI) est un questionnaire court utilisé pour évaluer le mésusage de la prescription d'opioïdes. Face à l'augmentation de la prescription d'antalgiques opioïdes pour les douleurs chroniques non cancéreuses (DCNC), cet outil est particulièrement utile lors des consultations médicales pour dépister le mésusage chez les patients utilisateurs d'opioïdes. Nous avons cherché à générer et à valider une traduction franco-européenne de la POMI. MéTHODES: Nous avons mené une étude psychométrique observationnelle, longitudinale et multicentrique avec une validation transculturelle. Tous les patients souffrant de DCNC, traités par opioïdes depuis au moins trois mois, suivis en structures douleur chronique et parlant le Français étaient éligibles. De septembre 2015 à novembre 2017, 163 patients ont été inclus et 154 analysés. Un pré-test a été réalisé sur un échantillon de patients représentatifs pour évaluer l'acceptabilité et la compréhension de la traduction. Les patients de l'étude ont rempli l'échelle POMI (phase TEST) au sein du centre investigateur et la fiabilité du testretest a été évaluée après deux à quatre semaines par un second remplissage de l'échelle POMI à domicile par les patients (phase RETEST). Ensuite, les propriétés psychométriques de l'échelle POMI ont été explorées (acceptabilité, cohérence interne, reproductibilité et validité externe). RéSULTATS: En raison d'une faible cohérence interne et reproductibilité, les items 4, 7 et 8 de l'échelle POMI originale ont été supprimés, et nous avons proposé une version française (Europe) à cinq questions (POMI-5F). La cohérence interne de l'échelle POMI-5F était bonne (α de Cronbach = 0,71), tout comme la fiabilité testretest (r = 0,65 [0,550,67]). La validité externe du POMI-5F, comparée à la cinquième édition du Manuel diagnostique et statistique des troubles mentaux (DSM-5), était modérée mais significative (r = 0,45; P < 0,001). Le score seuil optimal du POMI-5F pour indiquer un mésusage était de 2/5 (sensibilité = 0,95 et spécificité = 0,54). CONCLUSION: Nous avons généré et validé une traduction franco-européenne de l'échelle POMI, POMI-5F, pour une utilisation par les chercheurs et les médecins français afin d'identifier le mésusage des opioïdes chez les patients souffrant de DCNC.

BACKGROUND: Substance use disorders and non-substance addictive behaviors are major, growing health concerns. Efficient screening primary care settings encouraged but its widespread implementation is restricted without an appropriate screening approach for clinical practice or guidance for practitioners choose an appropriate screening test. This study aims to identify addictive disorder screening tests which are validated in primary care and suggest steps to help practitioners select the appropriate test. METHOD: A systematic review of the literature through Pubmed, PsycINFO and The Cochrane Library was performed from database inception to December 21, 2020. The search strategy included three research topics: screening, addictive disorders, and primary care. Selection criteria included published studies evaluating the validity of an addictive disorder screening test in primary care settings. RESULTS: 8638 papers were selected, and 50 studies were included. Seventeen questionnaires validated in primary care covered the main substance use disorders, but none screened for non-substance addictive behaviors. Tests such as ASSIST, S2BI, SUBS and TAPS screen for a variety of substance use disorders while others such as TICS and CAGE-AID only have a few questions to improve feasibility. However, some shorter tests had weaker psychometric properties. CONCLUSIONS: Seventeen addictive disorder screening tests validated in primary care are available. The feasibility and acceptability in primary care of the shorter tests needs to be assessed. A transversal screening test, adapted to the constraints of primary care, that enables clinicians to detect substance use disorders and non-substance addictive behaviors is needed.

OBJECTIVE: To determine whether profiles of patients with unbalanced type 2 diabetes (T2DM) and glycated haemoglobin (HbA1c) ≥ 10% could be identified on the basis of socio-demographic, behavioural, clinical, and biological characteristics. METHODS: Retrospective, cross-sectional, factorial analysis study of patients with T2DM treated for at least 1 year, with HbA1c ≥ 10%. Patients were recruited via medical analysis laboratories, France. Patients were followed up in general practice with possible recourse to specialist consultations. Data were collected by means of self-administered questionnaires sent by post. RESULTS: A total of 104 patients were included: 69 men and 35 women, with a median age of 66 ± 12 years, body mass index 30.7 ± 6.2kg/m2 and 47% in a vulnerable socio-economic situation. Fifty patients (48%) were followed exclusively by their general practitioners and only 30% had no compliance problems. Creatinuria was measured at least once during the year in 92% of patients, but microalbuminuria was measured in only 20%. Age, socio-economic precariousness, insulin treatment, and follow-up by several health professionals had a negative influence on quality of life (QoL). Two patient profiles were defined by factor analysis: (i) young, rural, smoker, socially isolated, precarious patient with poor compliance and QoL; and (ii) elderly, urban, regular physical activity, in a couple, without precariousness and with satisfactory QoL. CONCLUSIONS: Analysis of the characteristics of patients with T2DM and glycaemic imbalance reveals profiles that are useful in clinical practice for a personalized approach to treatment and active prevention of diabetes complications.

BACKGROUND: Intimate partner violence (IPV) is a prevalent yet underdiagnosed health issue, and primary care practitioners are in a unique front-line position to provide care and counsel for the victims. OBJECTIVE: To identify the signs and symptoms of women exposed to IPV who attended primary care, regardless motive of consultation. METHODS: Systematic review and meta-analysis on Cochrane, PubMed, Embase and CINAHL between 1946 and 2020. Eligible studies had to be original quantitative research, on women aged >15 years, attending primary care settings in Europe, North America and Australia and interviewed on their status as victims of IPV and on their signs and symptoms. RESULTS: Of 1791 articles identified, 57 were selected. Associations were found between IPV and signs and symptoms of depression [19 studies: overall odds ratio (OR) = 3.59, 95% confidence interval (CI; 2.7-4.7, I2 = 94.6%)], anxiety [9 studies: overall OR = 2.19, 95% CI (1.75-2.73, I2 = 84%)], gynaecological and/or sexually transmitted infections [6 studies: overall OR = 2.82, 95% CI (2.1-3.8, I2 = 41%)] and combination of somatic symptoms [5 studies: standard mean deviation = 0.795, 95% CI (0.62-0.97, I2 = 0%)]. CONCLUSIONS: Women exposed to IPV may present with clinical symptoms and signs other than bodily injury. Policy implications knowing these symptoms presented by women victims of IPV can help GPs identify and treat them. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42018089857.
