Rhinovirus characteristics associated with viremia in childhood asthma.

Although rhinoviruses play a major role in exacerbations of childhood asthma, the presence of rhinovirus (RV) RNA in plasma, referred to as viremia, has been investigated in a few studies. The aim of the study was to investigate the presence of rhinovirus viremia at the time of asthma exacerbation and to describe the molecular characteristics of rhinoviruses associated with viremia. We conducted an observational, prospective, multicenter study in eight pediatric hospitals (VIRASTHMA2). Preschool-aged recurrent wheezers (1-5 years) hospitalized for a severe exacerbation were included. Reverse-transcription polymerase chain reaction (RT-PCR) and molecular typing for RV/enteroviruses (EV) were performed on nasal swabs and plasma. Plasma specimens were available for 105 children with positive RT-PCR for RV/EV in respiratory specimens. Thirty-six (34.3%) had positive viremia. In plasma, 28 (82.4%) of the typable specimens were RV-C, five (14.7%) were EV-D68, and one was RV-A (2.9%). In all cases, the RV/EV type was identical in the plasma and respiratory specimens. In conclusion, RV/EV viremia is frequent in severe exacerbations of preschool recurrent wheezers, particularly in RV-C infections.

Nutritional and physical fitness parameters in adolescence impact cardiovascular health in adulthood.

BACKGROUND & AIMS: Cardiovascular diseases are the leading cause of mortality worldwide, originating in the first decades of life. A better understanding of their early determinants would allow for better prevention. This study aimed to evaluate the impact of nutritional and activity-related characteristics during adolescence on young adult cardiovascular risk factors. METHODS: The Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study included adolescents (aged 12.5-17.5 years) in 10 European centres. Four centres designed a nested cohort including 236 participants who were reassessed as young adults (21-32 years). Food consumption was evaluated by dietary recalls, physical activity by accelerometers, physical fitness using physical tests and nutritional knowledge by questionnaires. Cardiovascular health was assessed by Pathobiological Determinants of Atherosclerosis in Youth (PDAY) Study risk scores and its components. Factors associated with cardiovascular risk were identified using a multivariable regression model. RESULTS: Higher Diet Quality Index (DQI, P = 0.012) and nutritional knowledge (P = 0.015) were significantly associated with lower modified PDAY risk scores. Ultra-processed foods were associated with a lower non-high-density lipoprotein (non-HDL) cholesterol (P = 0.003), whereas DQI (P = 0.014) and Planetary Health Diet Index (P = 0.016) were associated with a higher HDL cholesterol. Higher DQI was also related to a lower body mass index (BMI, P = 0.006). In addition, cardiorespiratory fitness was related to a lower BMI (P = 0.004). CONCLUSIONS: Nutritional knowledge, diet quality and adherence to a sustainable diet in adolescence decrease cardiovascular risk in adulthood, whereas ultra-processed food consumption increases risk. These factors appear as targeted prevention tools for promoting a healthier adolescent lifestyle to decrease long-term cardiovascular risk.

Radiotherapy and prognostic factors in adnexal carcinomas: A retrospective study of 657 patients from the French CARADERM network.

BACKGROUND: Cutaneous adnexal carcinomas are a heterogeneous group of rare neoplasms. Surgical excision is the first-line treatment in localized stage. The use and effectiveness of radiotherapy have not been thoroughly evaluated in these neoplasms. OBJECTIVES: The present work analyses prognostic factors on outcomes in skin adnexal carcinomas, based on data from the CARADERM (CAncers RAres DERMatologiques) database. METHODS: Data were collected retrospectively including demographic data, tumour types and therapeutic characteristics of all patients included in the CARADERM database, with at least one informative follow-up visit. Analyses were performed on three populations: patients with complete resection of the primary tumour (ADJ/primary population), patients achieving complete remission after complete resection of a recurrent tumour (ADJ/recurrent population) and patients with unresectable locally advanced or metastatic tumours (ADV/MET population). Overall and recurrence/progression-free survivals at 3-year were analysed using Cox regression models. RESULTS: Radiotherapy did not affect overall survival (OS) in the ADJ/primary population. Adjusted recurrence-free survival (RFS) was significantly lower in the radiotherapy group in ADJ/primary group. Older patients had significantly poorer OS and RFS. Tumour size and immunosuppression were significantly associated with poorer RFS only. Radiotherapy had no effect on OS and RFS in the ADJ/recurrent population. Age was the only factor associated with a poorer OS. Radiotherapy was significantly associated with longer progression-free survival (PFS) in age-sex adjusted analysis in the ADV/MET population, without effect on OS. CONCLUSIONS: Our study shows that age, tumour size and immunosuppression are significantly associated with survival in localized adnexal carcinomas. Radiotherapy may improve PFS in the ADV/MET population but not in localized and recurrent carcinomas after complete excision.

[Impact of the mode of follow-up of preterm premature rupture of membranes before 36 weeks of gestation on the latency period]. / Impact du mode de suivi des ruptures prématurées des membranes avant 36 SA sur la durée de latence.

INTRODUCTION: Preterm premature rupture of membranes (PPROM) is the main cause of premature delivery, complicating 1-3% of all pregnancies. Conventional hospitalization (CH) is the most frequent mode of follow-up, but homecare (HC) seems to be an alternative. OBJECTIVES: Study of the impact of the monitoring mode on the duration of the latency period and on the latency ratio after PPROM, and analysis of the risk factors modifying this ratio. METHODS: This was a bicentric retrospective cohort study here-abouts including patients who presented a PPROM between 24 and 36weeks of gestation from 2016 to 2018. Patients had a follow-up in HC at Lille University Hospital center (UHC) and in CH at Nantes UHC according to two different follow-up protocols. The latency ratio corresponded to the real latency period divided by the latency period to theoretical term. RESULTS: We included 154 patients: 102 in HC and 52 in CH. The mean latency period was significantly higher in HC: 36.9±21.8 days, corresponding to an 85.5±23.7% latency ratio versus 20.2±12 days, corresponding to an 66.9±29.8% latency ratio in CH (P<0.001). The latency ratio in CH was correlated with term at PPROM (P=0.001). CONCLUSIONS: The duration of the latency period seems prolonged for PPROM followed by HC management versus CH in selected populations. This study suggests a benefit to HC in stable patients.

Factors associated with successful balloon catheter labor induction in women with a previous caesarean section: A retrospective single-center evaluation.

BACKGROUND: Labor induction of women with a history of uterine scarring is an increasingly frequent situation and one for which there are currently no clear professional recommendations favoring one method over another. The objectives of this study were to determine the success rate of balloon catheter induction in women with a history of caesarean section and to evaluate the main factors associated with vaginal delivery. MATERIALS AND METHODS: This single-center retrospective study was conducted between January 1, 2014, and December 31, 2018, in Lille, France, and included all women with one previous caesarean section who were induced by first-line balloon catheter induction. Multivariate analysis was performed to identify the factors associated with the primary outcome (vaginal delivery). RESULTS: Of the 310 women in the sample, 192 delivered vaginally (62 %). After adjustment, factors associated with successful induction (vaginal delivery) were the number of previous vaginal deliveries (odds ratio [OR] 1.37; 95 % confidence interval [CI] 1.04-1.81), evolution of the Bishop score after balloon removal (OR 1.24; 95 % CI 1.10-1.41), and the initial Bishop score (OR 1.17; 95 % CI 1.00-1.37). Uterine rupture was observed in three women (1 %). CONCLUSION: The vaginal delivery rate after balloon catheter induction in women with a previous caesarean section was 62 %. Prognostic factors for vaginal delivery include previous vaginal delivery, the initial Bishop score, and evolution of the Bishop score after balloon catheter induction.

Thrombosis recurrence and major bleeding in non-anticoagulated thrombotic antiphospholipid syndrome patients: Prospective study from antiphospholipid syndrome alliance for clinical trials and international networking (APS ACTION) clinical database and repository ("Registry").

BACKGROUND: Long-term anticoagulant therapy is generally recommended for thrombotic antiphospholipid syndrome (TAPS) patients, however it may be withdrawn or not introduced in routine practice. OBJECTIVES: To prospectively evaluate the risk of thrombosis recurrence and major bleeding in non-anticoagulated TAPS patients, compared to anticoagulated TAPS, and secondly, to identify different features between those two groups. PATIENTS/METHODS: Using an international registry, we identified non-anticoagulated TAPS patients at baseline, and matched them with anticoagulated TAPS patients based on gender, age, type of previous thrombosis, and associated autoimmune disease. Thrombosis recurrence and major bleeding were prospectively analyzed using Kaplan-Meier method and compared using a marginal Cox's regression model. RESULTS: As of June 2022, 94 (14 %) of the 662 TAPS patients were not anticoagulated; and 93 of them were matched with 181 anticoagulated TAPS patients (median follow-up 5 years [interquartile range 3 to 8]). The 5-year thrombosis recurrence and major bleeding rates were 12 % versus 10 %, and 6 % versus 7 %, respectively (hazard ratio [HR] 1.38, 95 % confidence interval [CI] 0.53 to 3.56, p = 0.50 and HR 0.53; 95 % CI 0.15 to 1.86; p = 0.32, respectively). Non-anticoagulated patients were more likely to receive antiplatelet therapy (p < 0.001), and less likely to have more than one previous thrombosis (p < 0.001) and lupus anticoagulant positivity (p = 0.01). CONCLUSION: Fourteen percent of the TAPS patients were not anticoagulated at recruitment. Their recurrent thrombosis risk did not differ compared to matched anticoagulated TAPS patients, supporting the pressing need for risk-stratified secondary thrombosis prevention trials in APS investigating strategies other than anticoagulation.
