Mediating effect of sleep in the association between social media use and mental health among French adolescents during the COVID-19 sanitary crisis.

OBJECTIVE/BACKGROUND: Social media use could have deleterious effects on mental health through short sleep duration and poor sleep quality among adolescents. This study aimed to investigate the mediating role of both sleep duration and sleep quality in the association between social media use and mental health among adolescents. PATIENTS/METHODS: We used cross-sectional data collected from adolescents in the EXIST pilot project conducted during COVID-19 pandemic. Adolescents self-reported wellbeing (WEMWBS), anxiety and depression (HADS) as mental health outcomes. We used ad-hoc questionnaires to assess social media use during weekdays and weekend days, and sleep duration and quality. Mediation analyses were carried out following Baron and Kenny's method, using adjusted linear regression models. RESULTS: A total of 340 adolescents (13.5 ± 0.6 years, 45.3 % girls) were included. Greater social media use, poorer sleep quality, and shorter sleep duration were associated with poorer mental health. Greater social media use was associated with poorer sleep quality only during the weekend days. The total effect of social media use during weekend days on anxiety (ß = 2.54; 95%CI [-1.59; 6.68]) was significantly conveyed through sleep quality (ß = 1.22; 95%CI [0.17; 2.62]; mediated proportion = 48.0 %) and duration (mediated proportion = 46.8 %). Mediated proportions ranged from 12.5 % to 20.6 % for wellbeing and depression. Mediating effects were not evident during weekdays. CONCLUSIONS: Sleep duration and quality mediated the association between social media use and mental health among adolescents during weekend days but not weekdays. Our findings highlight the importance of promoting healthy social media habits, especially during periods of increased reliance on digital platforms, such as COVID-19 pandemic.

Real world experience of therapeutic monitoring of medically treated prosthetic valve infective endocarditis by 18F-FDG-PET/CT.

INTRODUCTION: 18F-FDG-PET/CT is recommended to improve the diagnosis of prosthetic valve infective endocarditis (PVIE) and is a major criterion in the ESC-2015 classification. However, there is little evidence for its usefulness in the follow-up of medically treated PVIE patients. METHODS: A monocentric retrospective analysis of patients hospitalized for PVIE between January 2013 and December 2019 who were not treated with surgery and who had at least two 18F-FDG-PET/CT examinations during their medical management. RESULTS: Among 170 patients with PVIE, 117 were treated with antibiotic therapy but no surgery. Of these, 36 (31%) had at least two 18F-FDG-PET/CT examinations. At initial imaging, 28 patients had heterogeneous FDG uptake on their prosthetic valve and eight on their associated aortic graft. Hypermetabolism of spleen and bone marrow (HSBM) was observed in 18 and 19 patients, respectively. At the first follow-up 18F-FDG-PET/CT, 21 (58%) patients still had heterogeneous uptake, indicating persistent active endocarditis. HSBM was still present at the last follow-up imaging in four of the six patients with recurrent PVIE. CONCLUSION: 18F-FDG-PET/CT monitoring of medically treated patients with PVIE provides valuable additional information and prospective multicentric study should be conducted to assess its usefulness.

Family physicians' practices and attitudes towards HPV vaccination since extension of HPV vaccination to males.

OBJECTIVES: To describe family physicians' (FP) practices and attitudes towards HPV vaccination guidelines since its extension to males in 2021, and to identify levers to promote HPV vaccination in all adolescents. PATIENTS AND METHODS: Cross-sectional study among FPs established in France in 2021. We collected sociodemographic data, practices, opinions, and attitudes towards vaccination, and FPs' demands regarding training and information about HPV. We used logistic regression models to identify the variables associated with HPV vaccination proposal. RESULTS: Of 530 FPs included, 469 (88.5%) reported that they systematically proposed HPV vaccines to girls vs 335 (63.2%) to boys. A total of 366 (69.0%) FPs reported an increase in HPV vaccines proposal to all adolescents since the extension of HPV vaccination to males recommended by French guidelines. However, factors associated with HPV vaccination proposal differed by target females and target males. Setting and mode of practice, opinion about the number of recommended vaccines and HPV vaccines, and demands of training on HPV vaccines were associated with HPV vaccination proposal to target females. Whereas academic status, opinion about HPV vaccination guidelines extension to males, using continuing medical education as the main source of information on HPV vaccines, and demands for training on HPV vaccines were associated with HPV vaccination proposal to target males. CONCLUSIONS: Extension of HPV vaccination to males in French guidelines might have had a favorable impact on HPV vaccination proposal by FPs to adolescents. However, levers to promote HPV vaccination might differ according to the target population sex.

Antistaphylococcal penicillins vs. cefazolin in the treatment of methicillin-susceptible Staphylococcus aureus infective endocarditis: a quasi-experimental monocentre study.

Whether cefazolin is as effective and safer than antistaphylococcal penicillins (ASPs) for the treatment of methicillin-susceptible Staphylococcus aureus (MSSA) infective endocarditis (IE) is still debated in the absence of a randomized controlled trial. In this quasi-experimental study, we aimed to assess the effectiveness and safety of these two treatments in MSSA-IE, using the ASPs nationwide shortage in April 2016 as a unique opportunity to overcome the indication bias associated with observational studies. In this single-centre study, we compared patients with Duke-Li definite MSSA-IE treated with ASPs from January 2015 to March 2016 versus those treated with cefazolin from April 2016 to December 2018, when ASPs were not available. Effectiveness outcome was 90-day all-cause mortality. Safety outcomes included significant decrease in GFR and significant increase in serum liver enzymes. Logrank test was used to compare survival rates. Of 73 patients with MSSA-IE, 35 and 38 were treated with ASPs and cefazolin, respectively. Baseline patients' characteristics (demography, native or prosthetic valve IE, clinical characteristics, cardiac and septic complications) were similar between groups. Ninety-day all-cause mortality was 28.6% and 21.1%, in patients treated with ASPs and cefazolin, respectively (logrank p = 0.5727). There was no difference between groups for incident renal or liver toxicity events: acute kidney injury 45.7% vs. 44.7% (p = 0.933), increased ALT 5.7% vs. 13.2% (p = 0.432), bilirubin increase 5.7% vs. 10.5% (p = 0.676), in ASPs vs. cefazolin groups, respectively. In this quasi-experimental, effectiveness and safety did not statistically differ between ASPs and cefazolin for MSSA-IE treatment.

Comparison of a video versus paper questionnaire on functional limitation in lower limb osteoarthritis.

INTRODUCTION: The video Animated Activity Questionnaire (AAQ) was developed to assess the impact of lower limb osteoarthritis (OA) on daily functional activities. The objective of the study was to compare the video and the HOOS/KOOS paper questionnaires and to assess the effect of order of administration. MATERIAL AND METHODS: Patients recruited in the KHOALA cohort were randomized in two groups: AAQ questionnaire first (AAQ-first group) and HOOS (hip)/KOOS (knee) questionnaire first (H/KOOS-first group). Within group differences between AAQ and HOOS/KOOS scores were compared using a Student t-test. The Spearman correlation coefficient between AAQ score and HOOS/KOOS score was calculated in each group then compared, using Fisher z-transformation. RESULTS: Among 200 randomized patients, 188 (65.8 years, 66.0% women) completed the questionnaires: 99 in the AAQ-first group and 89 in the H/KOOS-first group. The AAQ score was 85.9 (SD: 13.7) in the AAQ-first versus 87.8 (SD: 13.1) in the H/KOOS-first group (p = 0.34). The H/KOOS score was 72.5 (SD: 21.2) in the AAQ-first versus 73.5 (SD: 18.4) in the H/KOOS-first group (p = 0.71). The Spearman correlation coefficient between AAQ and H/KOOS in the AAQ-first was 0.84[0.77-0.89] and 0.73[0.61-0.81] in H/KOOS-first group. These correlations differed between groups significantly (p = 0.02). CONCLUSION: This study found video AAQ and paper HOOS/KOOS questionnaire highly correlated, with a moderate but significant effect of order administration of video and paper questionnaires evidencing a stronger correlation when the videos were viewed first.

Implementation of antibiotic stewardship programmes in French ICUs in 2018: a nationwide cross-sectional survey.

BACKGROUND: Antibiotic stewardship programmes have a pivotal role in ICUs, but the level of implementation of these programmes at the regional or national level is not well known. OBJECTIVES: The aim of our study was to assess the level of implementation of antibiotic stewardship programmes in French ICUs. METHODS: We conducted a nationwide cross-sectional survey from January to March 2018 using an online questionnaire sent as an E-mail link to ICU specialists (one questionnaire per ICU). RESULTS: Overall, 113 out of 206 (55%) ICUs participated. Access to local epidemiology regarding bacterial resistance and antibiotic consumption data was reported in 84% and 65% of ICUs, respectively. Local guidelines for antibiotic use were available in 54% of ICUs. The duration of empirical antibiotic therapy was limited in 46% of cases, following the recommendation of an external expert in 33%. An antibiotic stewardship programme leader was reported at the hospital level by 94% of respondents, being an infectious disease physician in 80%. His/her role in the ICU was mostly to discuss specific cases (50%) and to provide advice on antibiotic prescriptions (26%). Regarding microbiological diagnosis, blood cultures were not processed at night or during weekends in 57%. Molecular biology and MS techniques were available in 62% and 59% of cases, respectively. Therapeutic drug monitoring of ß-lactams was available in 46% of cases. Forty-three percent of respondents knew the expression 'antimicrobial/antibiotic stewardship'. CONCLUSIONS: Antibiotic stewardship programmes are not optimally implemented in French ICUs. Improvement efforts and regular monitoring of the level of implementation are needed.

[Epidemiology of patients with eye-related emergencies in a university hospital: A cross-sectional study identifying factors associated with true emergency]. / Caractéristiques des patients examinés en urgence par un ophtalmologiste dans un CHU : résultats d'une étude transversale analytique identifiant des facteurs associés au caractère de véritable urgence.

PURPOSE: To describe epidemiological characteristics of outpatients examined by university medical center ophthalmologists in emergency rooms (ER), and to determine factors associated with true emergencies. METHODS: A monocentric cross-sectional study including all patients examined by an ophthalmologist in the ER of in the university hospital of Nancy over a two-month period was conducted. Demographics and medical characteristics were assessed. The visits were categorized by ophthalmologists as true emergencies or not. RESULTS: Among the 1,308 patients included, the median (IQR) age was 49 (32-64) years, and 56 % were males. The main reasons for seeking care were eye redness (32.6 %), eye pain (30.0 %), eye trauma (26.1 %), and visual loss (23.3 %). Nearly 40 % of the consultations were judged as not truly emergent. Factors significantly associated with true emergencies were: age under 60, male gender, some reasons for seeking care (visual loss, eye redness, eye pain), and a period of less than 3 days between symptom occurrence and the ER visit. CONCLUSION: The proportion of non-emergent ER visits was relatively high, and factors associated with true emergencies have been identified in our study. Standardized protocols may be useful to help emergency physicians and nurses to determine when to refer a patient to an ophthalmologist.

General practitioners' perceptions of vaccination controversies: a French nationwide cross-sectional study.

OBJECTIVES: We aimed to study general practitioners' (GPs') perceptions of vaccines that have been a subject of controversy in France. METHODS: A cross-sectional survey in 2014 asked a representative national sample of GPs, randomly selected from the exhaustive database of health professionals in France, about their perceptions of the likelihood of serious adverse events potentially associated with six different vaccines: for two of them the association was based on some scientific evidence, whereas for the other four this is not the case. We performed a cluster analysis to construct a typology of GPs' perceptions about the likelihood of these potential six associations. Factors associated with certain clusters of interest were identified using logistic regression models. RESULTS: Overall, 1582 GPs participated in the questionnaire survey (1582/1712 GPs who agreed to participate, 92%). Cluster analysis identified four groups of GPs according to their susceptibility to vaccine controversies: 1) limited susceptibility to controversies (52%); 2) overall unsure, but rejected the association between hepatitis B vaccine and multiple sclerosis (32%); 3) highly susceptible to controversies (11%); and 4) unsure (5%). We found that GPs who occasionally practised alternative medicine (OR 2.71, 95% CI 1.65-4.45), and those who considered information provided by mass media as reliable (OR 2.04, 95% CI 1.65-3.99) were more susceptible to controversies. CONCLUSIONS: GPs had different profiles of susceptibility to vaccination controversies, and most of their perceptions of these controversies were not based on scientific evidence.

Discrepancies between general practitioners' vaccination recommendations for their patients and practices for their children.

OBJECTIVES: The objectives of our study were to describe the vaccination recommendations by general practitioners (GPs) for their patients and practices for their children, and to identify any discrepancies between them. METHODS: Applying multiple correspondence analysis and agglomerative hierarchical cluster analysis to data from a 2014 cross-sectional survey of a national sample of GPs, we constructed a typology based on the patterns of associations between GPs' vaccine recommendations to their patients and practices to their own children's vaccinations. RESULTS: This study includes the 1038 GPs who reported that they had at least one child aged 2-25 years. Nearly half (47%, 482/1021) reported that all of their children were vaccinated against hepatitis B but that they did not always recommend that vaccine to patients; the same discordance was observed among 36% (369/1027) for the measles-mumps-rubella vaccine, 19% (194/1013) to 28% (290/1019) for routine and catch-up meningococcal C vaccination, and 27% (136/496) for the human papillomavirus vaccine. Cluster analysis showed that 37% (95% CI 33%-39%) of GPs reported an above-average rate of systematic vaccine recommendations for their patients, and most reported that all their children were vaccinated (low level of discordance), whereas 60% (95% CI 58%-64%) had a high level of discordance, that is, most reported that their children were vaccinated, but did not always recommend the same vaccines to their patients. CONCLUSIONS: Many GPs do not report the same attitude concerning the vaccination of their children and their patients. The reasons underlying these discrepancies, possibly including vaccine hesitancy, should be investigated.

The ANTIBIOPERF study: a nationwide cross-sectional survey about practices for ß-lactam administration and therapeutic drug monitoring among critically ill patients in France.

Our objective was to assess current practices about the administration (intermittent, extended, or continuous infusions) and therapeutic drug monitoring (TDM) of ß-lactam antibiotics and vancomycin in France. We conducted a nationwide cross-sectional survey in May-August 2015, using an online questionnaire, sent as an e-mail link to infectious disease specialists and intensive care specialists through national mailing lists. We used clinical vignettes of critically ill patients to assess physicians' practices about administration and TDM practices for amoxicillin, cloxacillin, piperacillin/tazobactam, cefotaxime, ceftazidime, cefepime, meropenem and vancomycin. In all, 507 physicians participated (507/1200, response rate 42%). TDM was rarely available for ß-lactams (from 16.5% (81/490) for cloxacillin to 30% (145/490) for ceftazidime), whereas vancomycin TDM was available in 97% (477/490) of the cases. In the clinical vignettes, ceftazidime and piperacillin/tazobactam were the ß-lactams administered most frequently by extended or continuous infusions (76% (336/440) and 57% (252/444), respectively). Gaps in knowledge about the duration of stability of intravenous ß-lactams were common (correct answers ranged from 8% (35/432) for cloxacillin to 33% (146/438) for ceftazidime). Most physicians (77%, 339/442) were convinced of the value of extended or continuous infusions for ß-lactams in critically ill patients, but 48% (211/442) did not have access to practical guidelines. Our survey found that most infectious disease and intensive care specialists are favourable to optimized administration of ß-lactams in critically ill patients. But the lack of guidelines and limited TDM availability for ß-lactams in hospitals are potential barriers to its implementation.

The EULAR Outcome Measures Library: development and an example from a systematic review for systemic lupus erythematous instruments.

OBJECTIVES: Patient reported outcomes (PROs) are relevant in rheumatology. Variable accessibility and validity of commonly used PROs are obstacles to homogeneity in evidence synthesis. The objective of this project was to provide a comprehensive library of "validated PROs". METHODS: A launch meeting with rheumatologists, PROs methodological experts, and patients, was held to define the library's aims and scope, and basic requirements. To feed the library we performed systematic reviews on selected diseases and domains. Relevant information on PROs was collected using standardised data collection forms based on the COSMIN checklist. RESULTS: The EULAR Outcomes Measures Library (OML), whose aims are to provide and to advise on PROs on a user-friendly manner albeit based on scientific grounds, has been launched and made accessible to all. PROs currently included cover any domain and, are generic or specifically target to the following diseases: rheumatoid arthritis, osteoarthritis, spondyloarthritis, low back pain, systemic lupus erythematosus, gout, osteoporosis, juvenile idiopathic arthritis, and fibromyalgia. Up to 236 instruments (106 generic and 130 specific) have been identified, evaluated, and included. The systematic review for SLE, which yielded 10 specific instruments, is presented here as an example. The OML website includes, for each PRO, information on the construct being measured and the extent of validation, recommendations for use, and available versions; it also contains a glossary on common validation terms. CONCLUSIONS: The OML is an in progress library led by rheumatologists, related professionals and patients, that will help to better understand and apply PROs in rheumatic and musculoskeletal diseases.

[Impact of training conferences on medical student's performance for the French National Ranking Examination in Lorraine University. The ETIMCEL experimental study]. / ÉTude de l'IMpact de Conférences sur la réussite aux ECN en Lorraine. Étude interventionnelle ETIMCEL.

PURPOSE: To describe factors associated with a better rank, and to assess the impact of training conferences on medical student's performance for the French National Ranking Examination (FNRE) in Lorraine University, France in 2012. METHODS: Between October 2011 and May 2012, assistant professors of the faculty of medicine of Nancy, France, organized a cycle of 15 conferences combining clinical cases theoretical training and student peer assessment. Data were recorded with a self-administered questionnaire in January 2012 to collect potential confounders. RESULTS: Among 287 students enrolled in the last year of medical school in 2011-2012 in Lorraine University, 195 (67.9%) of them registered to the cycle of conferences. Among the potential prognostic factors assessed, not repeating the first year of medical curriculum (P=0.013), the number of courses validated at the first session during the second part of the medical curriculum (P=0.002), absence of difficulties experienced in the fifth and sixth year (P=0.032) and a desired ranking among the best (P=0.011) were independently associated with a better rank at the FNRE. Regular participation in conferences was significantly and independently associated with a higher ranking (mean gain for the participation in 13 or more conferences: 873; mean gain by conference: 63). CONCLUSION: Regular participation in conferences provided by assistant professors and based on clinical cases theoretical training and student peer assessment was significantly associated with a higher ranking to the FNRE in Lorraine University in 2012.

Real-life rilpivirine resistance and potential emergence of an E138A-positive HIV strain in north-eastern France.

OBJECTIVES: To assess the prevalence of resistance to rilpivirine and mutations at position 138 in reverse transcriptase and to identify associated epidemiological and biological characteristics. METHODS: This retrospective study included 238 patients with available HIV-1 nucleotide sequences analysed at the Laboratory of Virology at the University Hospital of Nancy between January 2011 and June 2013. Resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) was evaluated according to the ANRS algorithm (version 23) and correlated with clinico-epidemiological and therapeutic data. The virus strains were analysed by evaluating the distance and distribution of the phylogenetic tree (MEGAv5). RESULTS: Among previously treated patients (111/238, 46.6%), 68/111 (61.3%) had received NNRTIs; all were rilpivirine-naive. The prevalence of rilpivirine resistance in the whole cohort was 12.6% (30/238), and was 10.2% (13/127) and 15.3% (17/111) in naive and pre-treated patients, respectively. The E138A mutation was the most frequent mutation associated with resistance to rilpivirine (P < 0.0001). The prevalence of the E138A mutation tended to increase over time, from 3.6% (2/55) during the first half of 2011 to 9.3% (4/43) during the first half of 2013 (P = 0.0614). Seven viral strains from seven naive male patients positive for the E138A mutation appeared in the same cluster. CONCLUSIONS: In our cohort of patients, we observed significantly increased resistance to rilpivirine, mostly because of the E138A mutation, probably due to an E138A strain circulating in newly diagnosed men who have sex with men. Taken together, our results emphasize the need to investigate the prevalence of rilpivirine resistance-associated mutations in the coming years both in France and abroad.

Menopause and modifiable coronary heart disease risk factors: a population based study.

OBJECTIVES: The aim of our study was to determine the effect of the menopause on various coronary heart disease (CHD) risk factors and on the global risk of CHD in a population based sample of women, making the difference between menopause and age related effects. STUDY DESIGN: The Third French MONICA cross-sectional survey on cardiovascular risk included 1730 randomly selected women, aged 35-64 years, representative from the general population. MAIN OUTCOME MEASURES: Women were defined as post-menopausal (postM; n=696), peri-menopausal (periM; n=183) or pre-menopausal (preM; n=659) based on the date of last menses. Socio-demographic, clinical and biological data were collected. Analyses of variance were used to compare means. RESULTS: PostM women had significantly higher age-adjusted levels of total cholesterol (6.0mmol/L in postM vs. 5.7mmol/L in preM, p<0.05) and LDL cholesterol (3.9mmol/L vs. 3.6mmol/L, p<0.05). There was no difference in HDL cholesterol or triglyceride levels, glycemia or blood pressure. Further adjustment on body mass index and hormonal treatments did not modify the results. No risk factor was significantly different between periM and postM. However, the Framingham 10-year risk of CHD was higher in postM, as compared with periM (5.1% vs. 5.0%, p<0.05). In postM women, lipids and the Framingham risk were not associated with elapsed time since menopause. CONCLUSIONS: The CHD risk increases during the sixth decade could be explained not only by estrogen deprivation but also by an effect on lipid profile, which is likely to occur in the peri-menopause period.

[Dyslipidemia in women after 50: age, menopause or both?]. / Dyslipidémies de la femme après 50ans : le rôle de l'âge et de la ménopause.

A high prevalence of cardiovascular risk factors is reported in postmenopausal women. The objective of this review was to determine whether the effect of the menopause on lipid profile remained after adjusting for age in middle age women. The results of 10 cross sectional studies and nine longitudinal studies added evidence of a worsening effect of the menopause on total cholesterol, LDL cholesterol and triglyceride plasmatic levels. This effect remained after adjustment for age. Menopausal estrogenic deficiency could be an explanation for those results, even if the hormonal replacement therapy effect on the lipid profile remains unclear.
