Management of work-related common mental disorders in general practice: a cross-sectional study.

BACKGROUND: General practitioners (GPs) often manage individuals with work-related common mental disorders (CMD: depressive disorders, anxiety and alcohol abuse). However, little is known about the ways in which they proceed. The aim of this study is to analyze GPs' management and patterns of referral to other health professionals of patients with work-related CMD and associated factors. METHOD: We used data from a cross-sectional study of 2027 working patients of 121 GPs in the Nord - Pas-de-Calais region in France (April - August 2014). Statistical analyses focused on patients with work-related CMD detected by the GP and examined the ways in which GPs managed these patients' symptoms. Associations between patient, work, GP and contextual characteristics and GPs' management were explored using modified Poisson regression models with robust variance. RESULTS: Among the 533 patients with work-related CMD in the study, GPs provided psychosocial support to 88.0%, prescribed psychotropic treatment to 82.4% and put 50.7% on sick leave. Referral rates to mental health specialists and occupational physicians were respectively 39.8 and 26.1%. Several factors including patients' characteristics (occupational and sociodemographic), GPs' characteristics and environmental data were associated with the type of management used by the GP. CONCLUSION: Our study emphasizes the major and often lonesome role of the GP in the management of patients with work-related CMDs. Better knowledge of the way GPs manage those patients could help GPs in their practice, improve patients care and be a starting point to implement a more collaborative care approach.

[Unexpected pregnancy, experience of sexual violence and contraception among women who use cannabis or other illegal substance in the Great Paris Region: Data from the 2016 Health Barometer]. / Grossesses non prévues, violences sexuelles et contraception chez les femmes consommant du cannabis ou d'autres substances psychoactives illégales en Île-de-France : données du Baromètre Santé 2016.

BACKGROUND: Women who use psychoactive substances could have higher levels of unplanned pregnancy and of difficulties accessing long-term contraceptive methods than those who do not use these substances. General population data on this topic are rare, particularly in France. METHODS: This study is based on data from the French Health Survey 2016, collected from women aged 15 to 49 years and living in the Great Paris region (N=1626). Use of illegal psychoactive substances (cannabis, substances used via intranasal or intravenous administration) were evaluated over the lifecourse and, for cannabis, over the 12 months preceding the study. Unplanned pregnancies were ascertained over the preceding 5 years, emergency contraception, abortion, and the experience of sexual violence during the lifecourse. We also studied the number of sexual partners in the preceding 12 months, as well as current contraception. Data were analyzed using weighted logistic regression models, adjusted for participants' sociodemographic characteristics and tobacco use. RESULTS: Women who use illegal substances have a higher probability than non-users to experience an unplanned pregnancy in the preceding 5 years (OR associated with lifecourse cannabis use: 1.61, 95% CI 1.00-2.58), to have used emergency contraception (ORs between 2.20 to 2.90), to have had an abortion (OR associated with lifecourse cannabis use: 1.77, 95% CI 1.26-2.49), and to have experienced sexual violence (ORs between 1.87 to 3.14). They also had more sexual partners than non-users, but did not differ in terms of contraception. CONCLUSION: In the general population, there is a relationship between women's use of illegal substances and their probability of experiencing sexual violence. These results should be brought to the attention of health professionals in contact with women, to help identify those who have addictive behaviors and identify their sexual and reproductive health needs.

Predictors of persistent maternal depression trajectories in early childhood: results from the EDEN mother-child cohort study in France.

BACKGROUND: Maternal depression in the pre- and postpartum period may set women on a course of chronic depressive symptoms. Little is known about predictors of persistently elevated depressive symptoms in mothers from pregnancy onwards. The aims of this study are to determine maternal depression trajectories from pregnancy to the child's fifth birthday and identify associated risk factors. METHOD: Mothers (N = 1807) from the EDEN mother-child birth cohort study based in France (2003-2011) were followed from 24-28 weeks of pregnancy to their child's fifth birthday. Maternal depression trajectories were determined with a semi-parametric group-based modelling strategy. Sociodemographic, psychosocial and psychiatric predictors were explored for their association with trajectory class membership. RESULTS: Five trajectories of maternal symptoms of depression from pregnancy onwards were identified: no symptoms (60.2%); persistent intermediate-level depressive symptoms (25.2%); persistent high depressive symptoms (5.0%); high symptoms in pregnancy only (4.7%); high symptoms in the child's preschool period only (4.9%). Socio-demographic predictors associated with persistent depression were non-French origin; psychosocial predictors were childhood adversities, life events during pregnancy and work overinvestment; psychiatric predictors were previous mental health problems, psychological help, and high anxiety during pregnancy. CONCLUSIONS: Persistent depression in mothers of young children is associated to several risk factors present prior to or during pregnancy, notably anxiety. These characteristics precede depression trajectories and offer a possible entry point to enhance mother's mental health and reduce its burden on children.

Excess non-psychiatric hospitalizations among employees with mental disorders: a 10-year prospective study of the GAZEL cohort.

OBJECTIVE: To examine whether non-psychiatric hospitalizations rates were higher in those with mental disorders. METHOD: In a cohort of 15,811 employees, aged 35-50 years in 1989, mental disorder status was defined from 1989 to 2000. Hospitalizations for all-causes, myocardial infarction (MI), stroke, and cancer, were recorded yearly from 2001 to 2011. Negative binomial regression models were used to estimate hospitalization rates over the follow-up. RESULTS: After controlling for baseline sociodemographic factors, health-related behaviors, self-rated health, and self-reported medical conditions, participants with a mental disorder had significantly higher rates of all-cause hospitalization [incidence rate ratio, IRR=1.20 (95%, 1.14-1.26)], as well as hospitalization due to MI [IRR=1.44 (95%, 1.12-1.85)]. For stroke, the IRR did not reach statistical significance [IRR=1.37 (95%, 0.95-1.99)] and there was no association with cancer [IRR=1.01 (95%, 0.86-1.19)]. A similar trend was observed when mental disorders groups were considered (no mental disorder, depressive disorder, mental disorders due to psychoactive substance use, other mental disorders, mixed mental disorders, and severe mental disorder). CONCLUSION: In this prospective cohort of employees with stable employment as well as universal access to healthcare, we found participants with mental disorders to have higher rates of non-psychiatric hospitalizations.

Socioeconomic position predicts long-term depression trajectory: a 13-year follow-up of the GAZEL cohort study.

Individuals with low socioeconomic position have high rates of depression; however, it is not clear whether this reflects higher incidence or longer persistence of disorder. Past research focused on high-risk samples, and risk factors of long-term depression in the population are less well known. Our aim was to test the hypothesis that socioeconomic position predicts depression trajectory over 13 years of follow-up in a community sample. We studied 12 650 individuals participating in the French GAZEL study. Depression was assessed by the Center for Epidemiological Studies-Depression scale in 1996, 1999, 2002, 2005 and 2008. These five assessments served to estimate longitudinal depression trajectories (no depression, decreasing depression, intermediate/increasing depression, persistent depression). Socioeconomic position was measured by occupational grade. Covariates included year of birth, marital status, tobacco smoking, alcohol consumption, body mass index, negative life events and preexisting psychological and non-psychological health problems. Data were analyzed using multinomial regression, separately in men and women. Overall, participants in intermediate and low occupational grades were significantly more likely than those in high grades to have an unfavorable depression trajectory and to experience persistent depression (age-adjusted ORs: respectively 1.40, 95% confidence interval (CI) 1.16-1.70 and 2.65, 95% CI 2.04-3.45 in men, 2.48, 95% CI 1.36-4.54 and 4.53, 95% CI 2.38-8.63 in women). In multivariate models, the socioeconomic gradient in long-term depression decreased by 21-59% in men and women. Long-term depression trajectories appear to follow a socioeconomic gradient; therefore, efforts aiming to reduce the burden of depression should address the needs of the whole population rather than exclusively focus on high-risk groups.

A qualitative evaluation of the use of Problem Management Plus (PM+) among Arabic-speaking migrants with psychological distress in France - The APEX study.

ABSTRACTBackground: Feasibility studies with non-French speaking migrants in France are needed to inform appropriate adaptation of psychosocial intervention procedures.Objective: To test the WHO Problem Management Plus (PM+) intervention protocol for Arabic-speaking migrants in the Paris metropolitan region.Methods: Between 2019 and 2021 we recruited participants from three accommodation centres receiving asylum seekers or migrants experiencing social and economic difficulties. Participants experiencing psychological distress underwent five PM + sessions with trained helpers. Feasibility was evaluated through 15 interviews with 8 participants, 4 helpers, and 3 study supervisors. Interview topics covered PM + implementation in general and for each component. We also sought to understand problems with delivery and gathered suggestions for improvement. Data were analysed thematically using a deductive approach.Results: We found implementation of PM + to be feasible, with predominantly positive reactions from participants, helpers and study staff. All intervention components were considered beneficial, with breathing exercises considered easy to implement and often sustained. Selection of problems and strategies to address them were described as challenging to execute. Psychosocial support from and rapport with helpers and the use of the native language were considered key strengths of the programme. However, we observed the need for complementary or higher intensity psychological support in some cases. Findings also highlighted the importance of addressing distress among non-specialist helpers delivering PM + . Finally, local guidance to social resources were suggested to be added in the protocol.Conclusion: PM + was well-liked and feasible, with cultural adjustments and increased access to community resources for migrants needed.

The World Health Organization Problem Management Plus (PM+) intervention was found to be a feasible and acceptable intervention for Arabic-speaking migrants in the Paris metropolitan region, with participants reporting improved mental health outcomes and satisfaction with the programme.The features of psychosocial support from and rapport with non-specialist helpers delivering PM + and the use of the native language were considered key strengths of the programme.The study documented perceived benefits of expanding PM + in scope and length, suggests the need for additional mental health services for non-specialist helpers, and highlights the importance of considering cultural and linguistic factors when providing mental health services to asylum seekers or migrants experiencing social and economic difficulties.

Close Proximity to Mining Is Associated with Increased Prevalence of the Drug Resistance-Associated Mutation dhps540E in Eastern Democratic Republic of the Congo.

Increasing sulfadoxine-pyrimethamine (SP) resistance in the Democratic Republic of the Congo (DRC) has threatened its use for prevention of malaria in one of the most malarious countries in the world. Using geographic information on mining operations in the DRC and genetic data on SP drug resistance markers from the 2013-2014 Demographic and Health Surveys, we evaluated associations between close residence to mining and the presence of mutations conferring resistance to sulfadoxine. Close residential proximity to mining was associated with increased prevalence odds ratio (POR) of the dhps540E mutation (POR: 2.11, 95% uncertainty interval: 1.15-3.96) with adjustments for confounding variables and space. Our findings indicate that exposure to mining is associated with increased presence of an antimalarial drug resistance haplotype that threatens effective use of SP for vulnerable populations. Areas actively engaged in mining could be considered for interventions to reduce the spread of emerging drug resistance in the DRC.

Impact of diabetes mellitus onset on sickness absence from work--a 15-year follow-up of the GAZEL Occupational Cohort Study.

AIMS: Previous studies do not provide an accurate estimate of the burden of diabetes on sickness absence. The aim of this study was to measure the impact of diabetes onset on absenteeism starting from the earliest occurrence of the disease. METHODS: The authors used data from a subsample of the French GAZEL cohort of 506 employees with incident diabetes and 2530 matched diabetes-free participants. Medically certified sickness absence data were obtained from company records (1989-2007). Number of sickness absence days and incidence rates of overall and cause-specific absence spells were compared according to diabetes status across three 5-year periods ranging from 10 years before to 5 years after onset of cases' diabetes. RESULTS: The mean number of sickness absence days was persistently higher in participants with diabetes compared with those without diabetes. This difference increased from 16.4 days (95% confidence interval 7.2-25.5) during the 5-year period preceding diabetes onset to 28.5 days (95% CI 16.1-40.9) during the following 5-year period (P = 0.04). This was due to a steeper relative increase in the incidence of long (but not short) absence spells in participants with diabetes versus those without diabetes [incidence rate ratios 1.33 (95% CI 1.08-1.64) and 1.75 (95% CI 1.43-2.14), respectively; P = 0.02]. Diabetes onset was associated with increased rates of circulatory and metabolic absence spells. CONCLUSIONS: Onset of diabetes is associated with a substantial increase in sickness absence. This suggests that in addition to its burden on work cessation, diabetes weighs heavily on working ability among people who manage to remain employed.

[Socio-demographic factors and use of health services for psychological reasons in young adults]. / Facteurs sociodémographiques et recours aux soins pour raisons psychologiques chez les jeunes adultes.

BACKGROUND: Although young adults exhibit a high rate of psychiatric disorders, their rate of access to mental health care is low compared with older age groups. Our study examined the relationship between socio-demographic factors and the use of health care services for psychological reasons. METHODS: We studied a community sample of 1103 French 22 to 35-year-old (TEMPO cohort study) who were surveyed by mailed questionnaire in 2009. Data were collected regarding participants' health (internalizing and externalizing psychological symptoms in 1991 and 2009), health care use (access to health professionals and psychotropic medications in case of psychological difficulties), and socio-demographic factors (sex, age, employment status, marital situation, social support). Parental history of depression was ascertained based on TEMPO participants' and their parents' reports (in the GAZEL cohort study). RESULTS: In the 12 months preceding the study, 16.7% of study participants saw a health professional and 12.8% took a psychotropic medication for psychological reasons. In multivariate regression, models adjusted for all socio-demographic and psychological characteristics, access to health professionals was associated with being unemployed/out of the labor force (OR=1.93; 95% CI=1.11-3.30), family situation (OR in participants living with a partner with no children: 2.16; 95% CI 1.26-3.72; OR in participants not living with a partner: 2.29; 95% CI=1.34-3.90), and having low social support (OR=1.75; 95% CI=1.21-2.54). The use of psychotropic medications was associated with female gender (OR=2.70; 95% CI=1.60-4.55), being unemployed/out of the labor force (OR=3.85; 95% CI=2.14-6.95), not living with a partner (OR=2.04; 95% CI=1.09-3.80) and having low social support (OR=1.65; 95% CI=1.05-2.59). Additionally, use of health services was associated with participants' and their parents' psychological difficulties.

A novel duplex qualitative real-time PCR assay for the detection and differentiation of Plasmodium ovale curtisi and Plasmodium ovale wallikeri malaria.

Background: P. ovale spp. infections are endemic across multiple African countries and are caused by two distinct non-recombining species, P. ovale curtisi (Poc) and P. ovale wallikeri (Pow). These species are thought to differ in clinical symptomatology and latency, but existing diagnostic assays have limited ability to detect and distinguish them. In this study, we developed a new duplex assay for the detection and differentiation of Poc and Pow that can be used to improve our understanding of these parasites. Methods: Repetitive sequence motifs were identified in available Poc and Pow genomes and used for assay development and validation. We evaluated the analytical sensitivity and specificity of the best-performing assay using a panel of samples from Tanzania and the Democratic Republic of the Congo (DRC), then validated its performance using 55 P. ovale spp. samples and 40 non-ovale Plasmodium samples from the DRC. Poc and Pow prevalence among symptomatic individuals sampled across three provinces of the DRC were estimated. Results: The best-performing Poc and Pow targets had 9 and 8 copies within the reference genomes, respectively. Our duplex assay had 100% specificity and 95% confidence lower limits of detection of 4.2 and 41.2 parasite genome equivalents/µl for Poc and Pow, respectively. Species was determined in 80% of all P. ovale spp.-positive field samples and 100% of those with >10 parasites/µl. Most P. ovale spp. field samples from the DRC were found to be Poc infections. Conclusions: We identified promising multi-copy targets for molecular detection and differentiation of Poc and Pow and used them to develop a new duplex real-time PCR assay that performed well when applied to diverse field samples. Though low-density Pow infections are not reliably detected, the assay is highly specific and can be used for high-throughput studies of P. ovale spp. epidemiology among symptomatic cases in malaria-endemic countries like the DRC.

Epidemiology of Plasmodium malariae and Plasmodium ovale spp. in Kinshasa Province, Democratic Republic of Congo.

Reports suggest non-falciparum species are an underappreciated cause of malaria in sub-Saharan Africa but their epidemiology is ill-defined, particularly in highly malaria-endemic regions. We estimated incidence and prevalence of PCR-confirmed non-falciparum and Plasmodium falciparum malaria infections within a longitudinal study conducted in Kinshasa, Democratic Republic of Congo (DRC) between 2015-2017. Children and adults were sampled at biannual household surveys and routine clinic visits. Among 9,089 samples from 1,565 participants, incidences of P. malariae, P. ovale spp., and P. falciparum infections by 1-year were 7.8% (95% CI: 6.4%-9.1%), 4.8% (95% CI: 3.7%-5.9%) and 57.5% (95% CI: 54.4%-60.5%), respectively. Non-falciparum prevalences were higher in school-age children, rural and peri-urban sites, and P. falciparum co-infections. P. falciparum remains the primary driver of malaria in the DRC, though non-falciparum species also pose an infection risk. As P. falciparum interventions gain traction in high-burden settings, continued surveillance and improved understanding of non-falciparum infections are warranted.

Validity of the 'protocol of oro-facial myofunctional evaluation with scores' for young and adult subjects.

UNLABELLED: The aims of this study were to analyse the validity, sensitivity and specificity of the protocol of oro-facial myofunctional evaluation with scores (OMES) for oro-facial myofunctional disorder (OMD) diagnosis in young and adult subjects. Eighty subjects were examined. The OMES was validated against the Nordic orofacial test-screening (NOT-S) protocol (criterion validity) (Spearman correlation test). The construct validity was tested by analysis of the ability of the OMES (i) to differentiate healthy subjects (n = 22) from temporomandibular disorder (TMD) patients (n = 22), which frequently have OMD (Mann-Whitney test) and (ii) to measure the changes that occurred in a subgroup with TMD between the period before and after oro-facial myofunctional therapy (T group, n = 15) (Wilcoxon test). Two speech therapists trained with the OMES participated as examiners (E). There was a statistically significant correlation between the OMES and NOT-S protocols, which was negative because the two scales are inverse (r = -0·86, P < 0·01). There was a significant difference between the healthy and TMD subjects regarding the oro-facial myofunctional status (OMES total score, P = 0·003). After therapy, the T group showed improvement in the oro-facial myofunctional status (OMES total score, P = 0·001). Inter- and intra-examiner agreement was moderate, and the reliability coefficients ranged from good to excellent. The OMES protocol presented mean sensitivity and specificity = 0·80, positive predictive value = 0·76 and negative predictive value = 0·84. CONCLUSION: The OMES protocol is valid and reliable for clinical evaluation of young and adult subjects, among them patients with TMD.

Remote mental health care interventions during the COVID-19 pandemic: An umbrella review.

Mitigating the COVID-19 related disruptions in mental health care services is crucial in a time of increased mental health disorders. Numerous reviews have been conducted on the process of implementing technology-based mental health care during the pandemic. The research question of this umbrella review was to examine what the impact of COVID-19 was on access and delivery of mental health services and how mental health services have changed during the pandemic. A systematic search for systematic reviews and meta-analyses was conducted up to August 12, 2022, and 38 systematic reviews were identified. Main disruptions during COVID-19 were reduced access to outpatient mental health care and reduced admissions and earlier discharge from inpatient care. In response, synchronous telemental health tools such as videoconferencing were used to provide remote care similar to pre-COVID care, and to a lesser extent asynchronous virtual mental health tools such as apps. Implementation of synchronous tools were facilitated by time-efficiency and flexibility during the pandemic but there was a lack of accessibility for specific vulnerable populations. Main barriers among practitioners and patients to use digital mental health tools were poor technological literacy, particularly when preexisting inequalities existed, and beliefs about reduced therapeutic alliance particularly in case of severe mental disorders. Absence of organizational support for technological implementation of digital mental health interventions due to inadequate IT infrastructure, lack of funding, as well as lack of privacy and safety, challenged implementation during COVID-19. Reviews were of low to moderate quality, covered heterogeneously designed primary studies and lacked findings of implementation in low- and middle-income countries. These gaps in the evidence were particularly prevalent in studies conducted early in the pandemic. This umbrella review shows that during the COVID-19 pandemic, practitioners and mental health care institutions mainly used synchronous telemental health tools, and to a lesser degree asynchronous tools to enable continued access to mental health care for patients. Numerous barriers to these tools were identified, and call for further improvements. In addition, more high quality research into comparative effectiveness and working mechanisms may improve scalability of mental health care in general and in future infectious disease outbreaks.

Extended biofilm susceptibility assay for Staphylococcus aureus bovine mastitis isolates: evidence for association between genetic makeup and biofilm susceptibility.

Staphylococcus aureus is one of the most prevalent causes of bovine mastitis. The antimicrobial treatment of this disease is currently based on antimicrobial susceptibility tests according to Clinical and Laboratory Standards Institute standards. However, various authors have shown a discrepancy between the results of this standard susceptibility test and the actual cure rate of the applied antimicrobial treatment. Increasing evidence suggests that in vivo biofilm formation by Staph. aureus, which is not assessed in the antimicrobial susceptibility tests, is associated with this problem, resulting in disappointing cure rates, especially for infections of longer duration. Previous data obtained with a limited number of strains showed that the extended biofilm antimicrobial susceptibility (EBS) assay reveals differences between strains, which cannot be derived from a standard susceptibility test or from a 24-h biofilm susceptibility test. The objective of this study was to test a collection of Staph. aureus bovine mastitis strains in the EBS assay and to model the effect of antimicrobial exposure, duration of antimicrobial exposure, and genotype profile of the strains on antimicrobial susceptibility. With the results from a previous study with the same collection of strains, the effect of genotype represented by accessory gene regulator gene (agr-type), the presence of insertional sequence 257 (IS257), intercellular adhesion (ica), and the ß-lactamase (blaZ) gene were entered as explanatory factors in a logistic regression model. The agr locus of Staph. aureus controls the expression of most of the virulence factors, represses the transcription of several cell wall-associated proteins, and activates several exoproteins during the post-exponential phase. The IS257 gene has been related to biofilm formation in vitro and was found earlier in 50% of the agr-type 2 strains. The ica gene cluster encodes for the production of an extracellular polysaccharide adhesin, termed polysaccharide intercellular adhesin, which appears to have an important role in pathogenic Staph. aureus infections. The blaZ gene encodes the presence of the penicillin resistance in the strain. The EBS assay together with the logistic regression model revealed that the duration of therapy is the most important factor of therapy outcome in this in vitro model. Furthermore, the effect of genotypic differences seems to be more important for therapy outcome than the antimicrobial used in this model.

[Active surveillance for scrapie in the Netherlands: effect of a breeding programme on the prevalence of scrapie in sheep (2002-2010)?]. / Acht jaar actieve scrapiesurveillance in Nederland: het effect van het fokprogramma op de prevalentie van scrapie bij het schaap (2002-2010).

The susceptibility of sheep to scrapie is modulated by the prion protein (PrP) genotype of the animal. An ambitious voluntary scrapie control programme was started in the Netherlands in 1998, based on selection of rams with theARR/ARR genotype for breeding. This programme was followed by an obligatory programme in 2004; the programme has been voluntary since 2007. We monitored the prevalence of PrP genotype frequencies and the prevalence of scrapie in the Dutch sheep population between 2002 and June 2010. Results showed that selection for scrapie-resistant sheep resulted in an increase in the ARR allele frequency in the Dutch national flock from 37.5% in 2005 to 61.4% in 2009. Moreover, surveillance data showed that there was a significant decrease in the prevalence of scrapie a few years after the start of the obligatory breeding programme, from more than 0.2% in 2004 to 0.015% in 2009. This decrease is a consequence of the increased number of scrapie-resistant sheep in the Dutch sheep population. To date, the results and the models based on the data show that the selective breeding programme should be continued for several years in order to successfully eradicate scrapie. It will be important to monitor the PrP frequency and scrapie prevalence in the Dutch sheep population in the coming years.

COVID-19 vaccine hesitancy among persons living in homeless shelters in France.

COVID-19 vaccine hesitancy is frequent and can constitute a barrier to the dissemination of vaccines once they are available. Unequal access to vaccines may also contribute to socioeconomic inequalities with regard to COVID-19. We studied vaccine hesitancy among persons living in homeless shelters in France between May and June 2020 (n = 235). Overall, 40.9% of study participants reported vaccine hesitancy, which is comparable to general population trends in France. In multivariate regression models, factors associated with vaccine hesitancy are: being a woman (OR = 2.55; 95% CI 1.40-4.74), living with a partner (OR = 2.48, 95% CI 1.17-5.41), no legal residence in France (OR = 0.51, 95% CI 0.27-0.92), and health literacy (OR = 0.38, 95% CI 0.21, 0.68). Our results suggest that trends in vaccine hesitancy and associated factors are similar among homeless persons as in the general population. Dissemination of information on vaccine risks and benefits needs to be adapted to persons who experience severe disadvantage.

Maternal post-natal depressive symptoms at 2 months: Effects of French antenatal preventive measures in the E.L.F.E. cohort.

BACKGROUND: Given the high incidence of perinatal maternal depression, implementation of preventive actions is crucial. In France, two prenatal preventive measures are available to the general population: early prenatal interview (EPI) and antenatal classes (ANC). OBJECTIVE: To explore the independent associations between EPI and / or ANC and maternal depressive symptoms at 2 months postpartum. METHOD: We used data from the Etude Longitudinale Française depuis l'Enfance (ELFE), a French national representative cohort of children and their parents, followed-up from birth to early adulthood. Data concerning characteristics were collected from the mothers during the maternity stay and between 6/8 weeks' post-partum. The level of depressive symptoms was scored by the French version of the Edinburgh Postnatal Depression Scale (EPDS) between 6/8 weeks' post-partum. We considered EPDS score ≥10 indicative of postnatal psychological distress (PPD) and EPDS ≥12 for postnatal depressive symptoms (PNDS). After data imputation, multivariate logistic regression analysis was performed. RESULTS: Among the 16,411 mothers included in our sample, 26% benefited both from EPI and ANC, 31.1 % of ANC, 7.7% of an EPI and 35% of neither; 20,1% presented PPD and 12,1% PNDS. The likelihood of presenting PPD was significantly higher in mothers who had neither had EPI nor ANC (OR = 1.15 (95% CI : 1.01-1.30). There was no association between receiving or not an EPI and/or ANC and presenting PNDS. CONCLUSIONS: Antenatal preventive measures may be helpful to prevent PPD at 2 months' post- partum, while PNDS do not seem to be influenced by these actions.

Cloning of cDNA for proteinase 3: a serine protease, antibiotic, and autoantigen from human neutrophils.

Closely similar but nonidentical NH2-terminal amino acid sequences have been reported for a protein or proteins in human neutrophils whose bioactivities is/are diverse (as a serine protease, antibiotic, and Wegener's granulomatosis autoantigen) but that share(s) several features: localization in the azurophil granules, a molecular mass of approximately 29 kD, reactivity with diisopropylfluorophosphate, and the ability to degrade elastin. We previously purified one such entity, termed p29b. Using a monospecific antibody, we have cloned from human bone marrow a cDNA encoding the complete p29b protein in its mature form, along with pre- and pro-sequences. The predicted amino acid sequence agrees closely with the NH2-terminal sequence obtained previously from purified p29b, as well as with sequences newly obtained from CNBr fragments. The primary structure is highly homologous to elastase, cathepsin G, T cell granzymes, and other serine proteases, and shares both the catalytic triad and substrate binding pocket of elastase. Hybridization of the full-length cDNA with restriction enzyme digests of human genomic DNA revealed only one fragment. This suggests that the closely related species described previously are the same, and can be subsumed by the term used for the first-described activity, proteinase 3. Proteinase 3 is more abundant in neutrophils than elastase and has a similar proteolytic profile and specific activity. Thus, proteinase 3 may share the role previously attributed to neutrophil elastase in tissue damage, and has the potential to function as an antimicrobial agent.

Hostility and depressive mood: results from the Whitehall II prospective cohort study.

BACKGROUND: The psychosocial vulnerability model of hostility posits that hostile individuals, given their oppositional attitudes and behaviours, are more likely to have increased interpersonal conflicts, lower social support, more stressful life events (SL-E) and higher likelihood of depression. However, little research has tested this hypothesis using large-scale prospective samples. The present study aims to assess the predictive value of hostility for depressive mood. METHOD: Data are from 3399 participants in the Whitehall II cohort study, aged 35-55 years at baseline (phase 1 1985-1988). Cynical hostility was measured at phase 1. Depressive mood was assessed at phase 7 (2002-2004). Sociodemographic characteristics, health-related behaviours, common mental disorders and antidepressant medication intake were assessed at phase 1. SL-E and confiding/emotional support were measured at phases 1, 2 (1989-1990) and 5 (1997-1999). RESULTS: Compared with participants in the lowest quartile of cynical hostility, those in the highest quartiles were more likely to have depressive mood [second quartile: odds ratio (OR) 1.58, 95% confidence interval (CI) 1.14-2.20; third quartile: OR 2.78, 95% CI 2.03-3.77; fourth quartile: OR 4.66, 95% CI 3.41-6.36] in analysis adjusted for sociodemographic characteristics. This graded association was somewhat attenuated (18%) but remained robust to adjustments for the covariates measured at baseline and follow-up. The association was also evident in participants free of mental health difficulties at baseline. CONCLUSIONS: Cynical hostility is a strong and robust predictor of depressive mood. Consideration of personality characteristics may be crucial to the understanding and management of depression.
