Multi-period capacity planning for maternity facilities in a perinatal network: A queuing and optimization approach

International audienceThis paper presents a methodology for determining bed capacity of maternity facilities in a perinatal network while considering the interaction among the facilities and long-term demand demographics. Maternity facilities, consisting of obstetrics units, basic and intensive care neonatal units, are heavily stochastic systems where capacity requirements cannot be set deterministically. Therefore, in this paper queuing theory is utilized to obtain a performance measure (the refused admission probability) which sets an analytical relationship between capacity and the required service level for each service unit in each maternity facility. This performance measure is embedded into a multi-period mixed-integer optimization model for determining the necessary capacity decisions in each time-period for each maternity facility in the network. The model takes into account demand demographics while minimizing the total cost of capacity decisions and refused admissions. The model is then applied to a real-world perinatal network in Hauts-de-Seine in Paris, France

Prevalence of and Risk Factors for Anal Oncogenic Human Papillomavirus Infection Among HIV-Infected Women in France in the Combination Antiretroviral Therapy Era

International audienceBackground. Little is known about the type-specific prevalence of anal human papillomavirus (HPV) infection and risk factors for anal high-risk (HR) HPV infection in human immunodeficiency virus (HIV)-infected women. Methods. A cross-sectional study of anal and cervical HPV infection was nested within a gynecological cohort of HIV-infected women. Specimens were tested for type-specific DNA using a polymerase chain reaction-based assay. Results. The study population consisted of 311 women with a median age of 45.3 years, of whom 42.8% originated from sub-Saharan Africa and 96.8% were receiving combination antiretroviral therapy. The median CD4 + cell count was 612/μL, and the HIV load was <50 copies/mL in 84.1%. HR-HPV types were detected in the anal canal in 148 women (47.6%) and in the cervix in 82 (26.4%). HPV-16 was the most prevalent type in both the anal canal (13.2% of women) and the cervix (5.1%). In multivariable analysis, factors associated with prevalent anal HR-HPV infection were CD4 + count <350/μL (odds ratio, 2.9; 95% confidence interval , 1.3-6.5), concurrent cervical lesions (2.6; 1.0-4.3), and cervical HR-HPV infection (1.8; 1.0-3.2). Conclusions. The high prevalence of HR-HPV types, including HPV-16, in the anal canal of HIV-positive women is concerning. Anal cancer screening should be considered for HIV-positive women as part of their routine care

: Consequences for the newborn of alcohol consumption during pregnancy

International audienceThis paper aims at showing the immediate and longterm consequences affecting newborns whose mothers did not reduce or stop their consumption of alcohol when they were pregnant; these women were chosen among women who also used psychoactive substances. A retrospective cohort was constituted of babies who were found to have been exposed in utero to one or more legal or illegal psychoactive substance(s) and who were born or hospitalized between 1999 and 2008 in a hospital near Paris. Among the cohort of 170 babies, 56 had mothers who had not modified their alcohol consumption when they were pregnant, 30 had mothers who had reduced their alcohol consumption, and 84 had mothers who declared having been abstinentUne cohorte rétrospective a été reconstituée par le repérage des enfants exposés in utero à une ou plusieurs substances psychoactives licites ou illicites, nés ou hospitalisés entre 1999 et 2008 dans un hôpital de la région parisienne. Sur les 170 nouveau-nés de mères de cette cohorte, 56 avaient une mère consommatrice inchangée d'alcool pendant toute sa grossesse, 30 avaient une mère dont la consommation s'était réduite, et 84 avaient une mère s'étant déclarée abstinente à l'alcool. Les nouveau-nés de mères consommatrices inchangées d'alcool pendant la grossesse étaient davantage prématurés (30 %) et hospitalisés dans le service de néonatologie (60,7 %) auxquels il avait fallu apporter des soins spécifiques pour des durées significativement plus longues que les autres enfants exposés in utero aux autres substances psychoactives (p < 0,005). Ils étaient plus souvent porteurs des effets de l'alcoolisation foetale (18 %) et placés en famille d'accueil (18 %

Impact of the 1st Wave of the COVID-19 Pandemic and Lockdown on In Utero Transfer Activity in the Paris Area, France

Background: To assess changes in the number and profile of in utero transfer requests during the first lockdown. Methods: An observational, retrospective, cohort study. All pregnant women, from the Paris area (France), for whom a request for in utero transfer to the transfer unit was made during the first lockdown in France (from 17 March to 10 May 2020) or during a mirror period (years 2016 to 2019) were included. We compared the numbers and proportions of various indications for in utero transfer, the rates of in utero transfer acceptance and the proportion of outborn deliveries. Results: 206 transfer requests were made during the lockdown versus 227, 236, 204 and 228 in 2016, 2017, 2018 and 2019, respectively. The relative proportion of requests for threatened preterm births and for fetal growth restriction decreased from 45% in the mirror period to 37% and from 8 to 3%, respectively. The transfer acceptance rates and outborn deliveries did not differ between time periods. Conclusions: Although a reduction in in utero transfer requests was observed for certain indications, the first lockdown was not associated with a decrease in acceptance rates nor in an increase in outborn births of pregnancies with a high risk of prematurity in the Paris area

Mental health of pregnant women during the SARS-CoV-2 pandemic in France: Evolution of self-perceived psychological state during the first lockdown, and anxiety frequency two months after the lockdown ended

International audiencePrevious pandemics and related lockdowns have had a deleterious impact on pregnant women's mental health. We studied the impact of the SARS-CoV-2/Covid-19 pandemic and France's first lockdown on pregnant women's mental health. A cross-sectional study was conducted in July 2020 using a web-questionnaire completed by 500 adult women who were pregnant during the first lockdown in France (March-May 2020). Questions focused on their self-perceived psychological state and affects they felt before and during the lockdown and anxiety symptomatology (HAD) two months after it ended. A robust variance Poisson regression model was used to estimate adjusted prevalence ratios (aPR) for anxiety and self-perceived psychological state evolution. One in five respondents (21.1%) reported psychological deterioration during lockdown. Associated determinants were: i) little or no social support (self-perceived) (aRP = 1.77, 95%CI[1.18-2.66]), ii) increased workload (1.65, [1.02-2.66]), and iii) poor/moderate knowledge about SARS-CoV-2 transmission (1.60, [1.09-2.35]). Seven percent of women reporting psychological deterioration had access to professional psychological support during lockdown, while 19% did not despite wanting it. Women reported heightened powerlessness (60.3%), frustration (64%) and fear (59.2%) during lockdown. One in seven respondents (14.2%, 95%CI[10.9-18.2]) had anxiety symptoms. Determinants associated: i) at least one pregnancy-related pathology (aPR = 1.82, 95%CI[1.15-2.88]), ii) overweightness or obesity (1.61, [1.07-2.43]), iii) one child under the age of six years in the household during the lockdown (3.26, [1.24-8.53]), iv) little or no social support (self-perceived) during the lockdown (1.66, [1.07-2.58]), v) friend or relatives diagnosed with Covid-19 or with symptoms of the disease (1.66; [1.06-2.60]), vi) no access to medication for psychological distress (2.86, [1.74-4.71]), and vii) unsuccessfully seeking exchanges with healthcare professionals about their pregnancy during the pandemic (1.66, [1.08-2.55]). Our results can guide prevention and support policies for pregnant women during pandemics, current or future, with or without lockdowns. Preventing perinatal mental health problems is essential to ensure a supportive environment for the child's development

High prevalence of Anal Human Papillomavirus-associated cancer precursors in a contemporary cohort of asymptomatic HIV-infected women

International audienceBackground. Although human immunodeficiency virus (HIV)-infected women are at high risk for anal cancer, few data have been published on prevalence of and risk factors for anal precancer and potential screening strategies in this risk group. Methods. A cross-sectional anal screening study was nested in a gynecological cohort of HIV-infected women. Anal swab specimens were collected for cytology and human papillomavirus (HPV) testing. High-resolution anoscopy, with biopsy when indicated, was systematically performed. Results. Among the 171 enrolled women, median age was 47.3 years and 98% were receiving combination antiretroviral therapy. Median CD4 + count was 655 cells/µL and HIV load was <50 copies/mL in 89% of subjects. High-grade anal intraepithelial neoplasia or worse (HG-AIN+) was diagnosed in 12.9% (n = 21). In multivariable analysis, a history of cervical squamous intraepithelial lesion (odds ratio [OR], 4.2; 95% confidence interval [CI], 1.1-16.4) and anal HPV-16 infection (OR, 16.1; 95% CI, 5.4-48.3) was associated with increased risk of HG-AIN+. Abnormal anal cytology and HPV-16 infection performed best as a screening strategy for HG-AIN+ histology, with positive likelihood ratios of 3.4 (95% CI, 2.3-5.1) and 4.7 (95% CI, 2.5-8.7) and negative likelihood ratios of 0.2 (95% CI, .07-.8) and 0.4 (95% CI, .2-.9), respectively. Conclusions. HIV-infected women with a history of HPV-associated cervical disease are at increased risk for HG-AIN+ and should be offered anal cancer screening. Anal cytology and HPV-16 genotyping had the best screening performance. Anal cytology is easy to perform routinely; it may be the best candidate for screening for HG-AIN among HIV-infected women

Raltegravir Concentrations in the Genital Tract of HIV-1-Infected Women Treated with a Raltegravir-Containing Regimen (DIVA 01 Study)▿

We studied the penetration of raltegravir and HIV shedding in the genital tract among 14 HIV-1-infected women receiving a raltegravir-containing regimen who had <40 copies/ml blood plasma (BP) HIV RNA. None of the cervicovaginal fluid (CVF) samples showed detectable HIV RNA. Median raltegravir concentrations were 235 ng/ml in BP and 93 ng/ml in CVF, with a CVF/BP ratio of approximately 2.3. This good penetration of raltegravir may contribute to the control of viral replication in the female genital tract

Pregnant women's unmet need to communicate with a health professional during the SARS-CoV-2 pandemic lockdown in France: The Covimater cross-sectional study.

During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic lockdown, communication between pregnant women and health professionals may have become complicated due to restrictions on movement and saturated health services. This could have impacts on pregnancy monitoring and women's wellbeing. We aimed to i) describe the unmet need of pregnant women living in France to communicate with health professionals about the pandemic and their pregnancy during the lockdown, ii) assess the socio-demographic, medical and contextual factors associated with this unmet need. The Covimater cross-sectional study, conducted in July 2020, includes data on 500 adult women's experiences of pregnancy during the first lockdown period in France (i.e., from March to May 2020). The women, all residents in metropolitan France, answered a web-based questionnaire about their conversations with health professionals during the lockdown, as well as their social and medical characteristics. A robust variance Poisson regression model was used to estimate crude or adjusted prevalence ratios (aPRs) for their unmet need to communicate with health professionals about the pandemic and their pregnancy. Forty-one percent of participants reported an unmet need to communicate with a health professional during the lockdown, mainly about the risk of transmitting SARS-CoV-2 to their baby and the consequences for the latter. Factors associated were: i) being professionally inactive (aPR = 1.58,CI95%[(1.14-2.21]), ii) having an educational level below secondary school diploma (1.38,[1.05,-1.81]), iii) having experienced serious arguments/violence (2.12,[1.28-3.52]), iv) being very worried about the pandemic (1.41,[1.11-1.78]), v) being primiparous (1.36,[1.06-1.74]) and vi) having had pregnancy consultations postponed/cancelled by health professionals during the lockdown (1.35,[1.06-1.73]). These results can be used to develop targeted strategies that ensure pregnant women are able to i) communicate with health professionals about the potential impact of the SARS-CoV-2 pandemic on their pregnancy, and ii) access up-to-date and reliable information on the consequences of SARS-CoV-2 for themselves and their child
