Acne-Related Quality of Life and Mental Health Among Adolescents: A Cross-Sectional Analysis.

BACKGROUNDS: Acne vulgaris is one of the most common skin conditions worldwide among adolescents. Beyond its physical manifestations, acne can leave invisible psychological scars. OBJECTIVES: We aimed to examine the protective and risk factors of acne-related quality of life, and its association with mental health outcomes. METHODS: The analysis included data collected in 2023 from adolescents enrolled in the SEROCoV-KIDS population-based cohort. By combining the Acne Severity and Acne-Quality of Life (Acne-QoL) scales, three groups were established: Acne-LowAQoL (adolescents with acne and low Acne-related Quality of Life), Acne-HighAQoL, and NoAcne-HighAQoL. We used multinomial and logistic regression to assess the association between health behaviours, these groups, and mental health outcomes. RESULTS: Among 335 adolescents (mean age 16.1 years [SD 1.8], 56% female), 65 (19.4%) reported experiencing acne while maintaining a high Acne-QoL, 26 (7.7%) reported having acne and a low Acne-QoL and 244 (72.9%) reported having nearly no acne. Low engagement in physical activity (aOR: 0.30, 95% CI: 0.12-0.77), addictive use of social media (aOR: 3.78, 95%CI: 1.60-8.96), and prolonged screen time (aOR: 2.99, 95%CI: 1.26-7.08) were independently associated with Acne-LowAQoL. Conversely, those from the group Acne-HighAQoL reported higher social support (aOR: 1.95, 95%CI: 1.07-3.54). Adolescents with Acne-LowAQoL showed lower levels of self-esteem, resilience, and increased psychological distress. CONCLUSIONS: Among adolescents with acne, physical activity and social support were positively associated with good acne-related quality of life, which translated into better mental health. In contrast, screen time and social media use notably reduced it. Dermatologists should incorporate these considerations into clinical practice to ensure effective patient care.

Psychosocial factors mediate social inequalities in health-related quality of life among children and adolescents.

BACKGROUND: The present analysis aimed to assess the mediating role of psychosocial and behavioural factors in socio-economic inequalities in health-related quality of life (HRQoL) among children and adolescents. METHODS: Cross-sectional data was drawn from the randomly selected SEROCoV-KIDS cohort study in Geneva, Switzerland. Associations of socio-economic conditions (parents' highest education, household financial situation) with HRQoL, psychosocial (parent-child relationship, school difficulties, friends, extracurricular activities) and behavioural factors (screen time, physical activity, green spaces time, sleep duration), along with associations of psychosocial and behavioural factors with HRQoL, were evaluated with generalized estimating equations. Counterfactual mediation analyses were conducted to test pathways linking socio-economic conditions to HRQoL. RESULTS: Of 965 children and 816 adolescents, those with disadvantaged financial circumstances were more likely to have a poor HRQoL (adjusted Odds Ratio [aOR]: 3.80; 95% confidence interval [CI]: 1.96-7.36 and aOR: 3.66; 95%CI: 2.06-6.52, respectively). Psychosocial characteristics mediated 25% (95%CI: 5-70%) and 40% (95%CI: 18-63%) of financial disparities in HRQoL among children and adolescents, respectively. Health behaviours were weakly patterned by socio-economic conditions and did not contribute to financial differences in HRQoL. CONCLUSIONS: These findings provide empirical evidence for mechanisms explaining socio-economic disparities in child HRQoL and could inform interventions aimed to tackle health inequalities.

[18F]DPA-714: Effect of co-medications, age, sex, BMI and TSPO polymorphism on the human plasma input function.

PURPOSE: We aimed to assess the effect of concomitant medication, age, sex, body mass index and 18-kDa translocator protein (TSPO) binding affinity status on the metabolism and plasma pharmacokinetics of [18F]DPA-714 and their influence on the plasma input function in a large cohort of 201 subjects who underwent brain and whole-body PET imaging to investigate the role of neuroinflammation in neurological diseases. METHODS: The non-metabolized fraction of [18F]DPA-714 was estimated in venous plasma of 138 patients and 63 healthy controls (HCs; including additional arterial sampling in 16 subjects) during the 90 min brain PET acquisition using a direct solid-phase extraction method. The mean fraction between 70 and 90 min post-injection ([18F]DPA-71470-90) and corresponding normalized plasma concentration (SUV70-90) were correlated with all factors using a multiple linear regression model. Differences between groups (arterial vs venous measurements; HCs vs patients; high- (HAB), mixed- (MAB) and low-affinity binders (LAB); subjects with vs without co-medications, females vs males were also assessed using the non-parametric Mann-Whitney or Kruskal-Wallis ANOVA tests. Finally, the impact of co-medications on the brain uptake of [18F]DPA-714 at equilibrium was investigated. RESULTS: As no significant differences were observed between arterial and venous [18F]DPA-71470-90 and SUV70-90, venous plasma was used for correlations. [18F]DPA-71470-90 was not significantly different between patients and HCS (59.7 ± 12.3% vs 60.2 ± 12.9%) despite high interindividual variability. However, 47 subjects exhibiting a huge increase or decrease of [18F]DPA-71470-90 (up to 88% or down to 23%) and SUV70-90 values (2-threefold) were found to receive co-medications identified as inhibitors or inducers of CYP3A4, known to catalyse [18F]DPA-714 metabolism. Comparison between cortex-to-plasma ratios using individual input function (VTIND) or population-based input function derived from untreated HCs (VTPBIF) indicated that non-considering the individual metabolism rate led to a bias of about 30% in VT values. Multiple linear regression model analysis of subjects free of these co-medications suggested significant correlations between [18F]DPA-71470-90 and age, BMI and sex while TSPO polymorphism did not influence the metabolism of the radiotracer. [18F]DPA-714 metabolism fell with age and BMI and was significantly faster in females than in males. Whole-body PET/CT exhibited a high uptake of the tracer in TSPO-rich organs (heart wall, spleen, kidneys…) and those involved in metabolism and excretion pathways (liver, gallbladder) in HAB and MAB with a strong decrease in LAB (-89% and -85%) resulting in tracer accumulation in plasma (4.5 and 3.3-fold increase). CONCLUSION: Any co-medication that inhibits or induces CYP3A4 as well as TSPO genetic status, age, BMI and sex mostly contribute to interindividual variations of the radiotracer metabolism and/or concentration that may affect the input function of [18F]DPA-714 and consequently its human brain and peripheral uptake.

A public health value-based healthcare paradigm for HIV.

BACKGROUND: HIV patients face considerable acute and chronic healthcare needs and battling the HIV epidemic remains of the utmost importance. By focusing on health outcomes in relation to the cost of care, value-based healthcare (VBHC) proposes a strategy to optimize quality of care and cost-efficiency. Its implementation may provide an answer to the increasing pressure to optimize spending in healthcare while improving patient outcomes. This paper describes a pragmatic value-based healthcare framework for HIV care. METHODS: A value-based HIV healthcare framework was developed during a series of roundtable discussions bringing together 16 clinical stakeholder representatives from the Belgian HIV reference centers and 2 VBHC specialists. Each round of discussions was focused on a central question translating a concept or idea to the next level of practical implementation: 1) how can VBHC principles be translated into value-based HIV care drivers; 2) how can these value-based HIV care divers be translated into value-based care objectives and activities; and 3) how can value-based HIV care objectives and activities be translated into value-based care indicators. Value drivers were linked to concrete objectives and activities using a logical framework approach. Finally, specific, measurable, and acceptable structure, process and outcomes indicators were defined to complement the framework. RESULTS: Our framework identifies 4 core value areas where HIV care would benefit most from improvements: Prevention, improvement of the cascade of care, providing patient-centered HIV care and sustaining a state-of-the-art HIV disease management context. These 4 core value areas were translated into 12 actionable core value objectives. For each objective, example activities were proposed. Indicators are suggested for each level of the framework (outcome indicators for value areas and objectives, process indicators for suggested activities). CONCLUSIONS: This framework approach outlines how to define a patient- and public health centered value-based HIV care paradigm. It proposes how to translate core value drivers to practical objectives and activities and suggests defining indicators that can be used to track and improve the framework's implementation in practice.

Not only disease activity but also chronic hypertension and overweight are determinants of pregnancy outcomes in patients with systemic lupus erythematosus.

INTRODUCTION: Pregnancies in women with lupus nephritis are at high-risk of complications, while scarcity of scientific knowledge on prognostic factors impedes a fair medical counseling. We aimed to identify determinants associated with maternal and fetal complications. MATERIALS: We retrospectively reviewed medical charts of pregnancies that lasted more than 22 weeks in 66 patients with pre-existing lupus nephritis between 2004 and 2013 in France. Univariate and multivariate analyses were conducted to identify determinants for maternal complications, lupus renal flare and fetal prematurity or death. RESULTS: Eighty-four pregnancies were identified. A maternal complication occurred in 31 pregnancies (36.9%): mostly preeclampsia (17 pregnancies, 20.2%) and renal flares (12 pregnancies, 14.3%). Overall fetal survival was 94.0% (79/84). Maternal pregnancy complications were independently associated with prepregnancy body mass index >25 kg/m2 (OR 3.81, 95% CI 1.03-14.09) and immunological activity (positive anti-dsDNA antibodies or Farr assay lupus) (OR 4.95, 95% CI 1.33-18.43). Renal lupus flares were independently associated with maternal age (OR 1.50, 95% CI 1.12-2.01) and prepregnancy immunological activity (OR 15.99, 95% CI 1.57-162.68) while a remission time >12 months had a protective effect (OR 0.17, 95% CI 0.04-0.68). Three parameters were associated with a higher risk of fetal prematurity or death: a prepregnancy body mass index >25 kg/m2 (HR 3.58, 95% CI 1.45-8.83), hypertension (HR 8.97, 95% CI 3.32-24.25), and immunological activity (HR 3.34, 95% CI 1.30-8.63). CONCLUSION: Maternal age, prepregnancy hypertension, body mass index >25 kg/m2 and lupus immunological activity may be considered as the main determinants for fetal and maternal complications. A remission time above 12 months for patients with lupus nephritis could be associated with a reduced risk of renal flare during pregnancy.

High-dose transdermal nicotine in Parkinson's disease patients: a randomized, open-label, blinded-endpoint evaluation phase 2 study.

BACKGROUND AND PURPOSE: Studies of the effects of nicotine on motor symptoms in Parkinson's disease (PD) brought out discordant results. The aim of the present study was to evaluate the efficacy and safety of high doses of transdermal nicotine on motor symptoms in PD. METHODS: Forty PD patients were randomly assigned to a treated and untreated arm in an open-label study. Treated patients received increasing doses of nicotine to reach 90 mg/day by 11 weeks. This dosage was maintained for 28 weeks (W39) and then reduced over 6 weeks. Final evaluation was performed 6 weeks after washout. The main outcome measure was the OFF-DOPA Unified Parkinson's Disease Rating Scale (UPDRS) motor score measured on video recordings by raters blinded to the medication status of the patients. RESULTS: There was no significant difference in OFF-DOPA UPDRS motor scores between the nicotine-treated and non-treated groups, neither at W39 (19.4 ± 9.3 vs. 21.5 ± 14.2) nor considering W39 differences from baseline (-1.5 ± 12.1 vs. +0.9 ± 12.1). The 39-item Parkinson's disease questionnaire scores decreased in nicotine-treated patients and increased in non-treated patients, but the difference was not significant. Overall tolerability was acceptable, and 12/20 treated patients reached the maximal dosage. CONCLUSIONS: High doses of transdermal nicotine were tolerated, but our study failed to demonstrate significant improvement in UPDRS motor scores. Improvement in unblinded secondary outcomes (UPDRS-II, UPDRS-IV, doses of l-DOPA equivalents) suggest a possible benefit for patients treated with nicotine, which should be confirmed in larger double blind, placebo-controlled studies.

[Rectal giant inflammatory pseudopolyps : an unusual cause of rectal bleeding]. / Pseudo-polypes inflammatoires géants du rectum : une cause rare de rectorragies.

Giant inflammatory pseudopolyps are begnin lesions that have been described usually in patients with inflammatory bowel disease. Rarely, they have been reported in patient without any colonic disease. We report the case of a 40-old woman, without previous colonic pathology, who presented with rectal giant inflammatory pseudopolyps revealed by rectal bleeding.

Les pseudo-polypes inflammatoires géants sont des tumeurs bénignes du tube digestif. Ils ont principalement été décrits chez les malades atteints de maladie inflammatoire chronique de l'intestin. Exceptionnellement, ils ont été rapportés chez des patients n'ayant aucune pathologie digestive. Nous rapportons l'observation d'une patiente de 40 ans, présentant de multiples pseudo-polypes inflammatoires géants du rectum, en l'absence de toute autre pathologie colorectale, révélés par des rectorragies.

Th-17 Alloimmune Responses in Renal Allograft Biopsies From Recipients of Kidney Transplants Using Extended Criteria Donors During Acute T Cell-Mediated Rejection.

Although renal transplantation using expanded criteria donors has become a common practice, immune responses related to immunosenescence in those kidney allografts have not been studied yet in humans. We performed a retrospective molecular analysis of the T cell immune response in 43 kidney biopsies from patients with acute T cell-mediated rejection including 25 from recipients engrafted with a kidney from expanded criteria donor and 18 from recipients grafted with optimal kidney allograft. The clinical, transplant and acute T cell-mediated rejection characteristics of both groups were similar at baseline. The expression of RORγt, Il-17 and T-bet mRNA was significantly higher in the elderly than in the optimal group (p = 0.02, p = 0.036, and p = 0.01, respectively). Foxp3 mRNA levels were significantly higher in elderly patients experiencing successful acute T cell-mediated rejection reversal (p = 0.03). The presence of IL-17 mRNA was strongly associated with nonsuccessful reversal in elderly patients (p = 0.008). Patients with mRNA IL17 expression detection and low mRNA Foxp3 expression experienced significantly more treatment failure (87.5%) than patients with no mRNA IL17 expression and/or high mRNA Foxp3 expression (26.7%; p = 0.017). Our study suggests that the Th17 pathway is involved in pathogenesis and prognosis of acute T cell-mediated rejection in recipients of expanded criteria allograft.

[18F]DPA-714 PET imaging of translocator protein TSPO (18 kDa) in the normal and excitotoxically-lesioned nonhuman primate brain.

PURPOSE: We aimed to characterize pharmacologically the TSPO- radioligand [(18)F]DPA-714 in the brain of healthy cynomolgus monkeys and evaluate the cellular origin of its binding in a model of neurodegeneration induced by intrastriatal injection of quinolinic acid (QA). METHODS: [(18)F]DPA-714 PET images were acquired before and at 2, 7, 14, 21, 49, 70, 91 days after putaminal lesioning. Blocking and displacement studies were carried out (PK11195). Different modelling approaches estimated rate constants and V T (total distribution volume) which was used to measure longitudinal changes in the lesioned putamen. Sections for immunohistochemical labelling were prepared at the same time-points to evaluate correlations between in vivo [(18)F]DPA-714 binding and microglial/astrocytic activation. RESULTS: [(18)F]DPA-714 showed a widespread distribution with a higher signal in the thalamus and occipital cortex and lower binding in the cerebellum. TSPO was expressed throughout the whole brain and about 73 % of [(18)F]DPA-714 binding was specific for TSPO in vivo. The one-tissue compartment model (1-TCM) provided good and reproducible estimates of V T and rate constants, and V T values from the 1-TCM and the Logan approach were highly correlated (r (2) = 0.85). QA lesioning induced an increase in V T, which was +17 %, +54 %, +157 % and +39 % higher than baseline on days 7, 14, 21 and 91 after QA injection, respectively. Immunohistochemistry revealed an early microglial and a delayed astrocytic activation after QA injection. [(18)F]DPA-714 binding matched TSPO immunopositive areas and showed a stronger colocalization with CD68 microglia than with GFAP-activated astrocytes. CONCLUSION: [(18)F]DPA-714 binds to TSPO with high specificity in the primate brain under normal conditions and in the QA model. This tracer provides a sensitive tool for assessing neuroinflammation in the human brain.

Biotherapies for Parkinson disease.

The clinical use of biotherapies in Parkinson disease already has 30 years' history. The transplantation of dopamine fetal cells in the striatum of advanced patients has proved to be relevant in some patients but randomized efficacy trials in the US have provided disappointing results. However, cell therapies might come back on stage with the use of stem cells in the future. Gene therapy is a more recent strategy relying on viral vectors able to transduce genes coding either for the enzymes that can increase neurotransmitters production or genes for trophic factors. Several approaches have been developed in PD and have been experimented in patients. Although, some of the studies have evidenced insufficient clinical benefit, other programs, such as those using dopamine replacement techniques are promising. We find fresh hope in this field that might be the future of PD treatment. It remains however that advanced PD might not be the ideal condition to properly benefit from biotherapies and there is a need of studies at earlier stages of the disease, a time where major change in the disease course might be expected.

Prevalence of and risk factors for suicidal ideation in adolescents during the COVID-19 pandemic: a cross-sectional study.

BACKGROUND AND OBJECTIVES: Pandemic-related life changes may have had a deleterious impact on suicidal behaviours. Early detection of suicidal ideation and identification of subgroups at increased risk could help prevent suicide, one of the leading causes of death among adolescents worldwide. Here, we aimed to investigate the prevalence of and risk factors for suicidal ideation in adolescents using a population-based sample from Switzerland, two years into the pandemic. METHODS: Between December 2021 and June 2022, adolescents aged 14 to 17 years already enrolled in a population-based cohort study (State of Geneva, Switzerland) were asked about suicidal ideation over the previous year. In addition to a regression model, we conducted a network analysis of exposures which identified direct and indirect risk factors for suicidal ideation (i.e. those connected through intermediate risk factors) using mixed graphical models. RESULTS: Among 492 adolescents, 14.4% (95% CI: 11.5-17.8) declared having experienced suicidal ideation over the previous year. Using network analysis, we found that high psychological distress, low self-esteem, identifying as lesbian, gay or bisexual, suffering from bullying, extensive screen time and a severe COVID-19 pandemic impact were major risk factors for suicidal ideation, with parent-adolescent relationship having the highest centrality strength in the network. CONCLUSION: Our results show that a significant proportion of adolescents experience suicidal ideation, yet these rates are comparable with pre-pandemic results. Providing psychological support is fundamental, with a focus on improving parent-adolescent relationships.

Parental functioning improves the developmental quotient of pediatric liver transplant recipients.

Psychomotor development in pediatric liver transplant (LT) recipients depends on several factors. Our aim was to evaluate the importance of parental involvement and family dynamics on psychomotor development by assessing (i) children and parents individually, (ii) the parent-child relationship, and (iii) the correlation between parental functioning and patient outcome, all before and after LT. Age-appropriate scales were used before and after LT. Twenty-one patients, 19 mothers, and 16 fathers were evaluated. Developmental quotient (DQ): No subjects scored in the "very good" range. The proportion of children with deficits increased from LT to two yr: 17.6% vs. 28.6%. Subjects 0-2 yr were more likely to have normal DQ at transplant (66.7% vs. 50% for older children). Abnormal DQ was more prevalent two yr post-LT in children older at LT (p = 0.02). The mother-child relationship was normal in 59% of families pre-LT and in 67% at two yr. The relationship was more favorable when the child received a transplant as an infant (p = 0.014 at 12 months post-LT). Normal DQ was associated with higher maternal global functioning score pre-LT (p = 0.03). Paternal performance scores were higher than maternal scores. Children transplanted after two yr of age suffer greater long-term deficits than those transplanted as infants.

[Could speech rate of Wilson's disease dysarthric patient be improved in dual task condition?]. / Le débit de parole du patient wilsonien dysarthrique peut-il être amélioré en condition de double tâche?

INTRODUCTION: Dysarthria is one of the first sign of neurological Wilson's disease and is often characterized by a decreased speech rate. The aim of this study is to determine the abilities of Wilson's disease dysarthric patients to control their speech rate. We examined the impact of dual-tasking on the speech rate of patients as compared to healthy control speakers and in relation with their ability to accelerate speech rate when instructed to do so. METHODS: Twenty-six patients and twenty-six age- and sex-matched healthy controls repeated a sentence during 20 seconds at a comfortable speech rate used as reference. They were then asked to perform the same repetition task but in dual task conditions, in which sentence repetition was done while performing three types of executive grapho-motor tasks. Finally, the ability to control speech rate was tested by asking the speakers to perform the sentence repetition task alone but at a fast rate of speech. RESULTS: A significantly slower speech rate was observed for all patients as compared to controls. In the dual-task conditions, while the speech rate of healthy speakers accelerated significantly, two behaviors are found for the patients. Forty-two percent of the patients reproduced the control pattern with a significant increased in speech rate, while the other group significantly decreased their speech rate. Comparison of the ability of the two groups to intentionally modulate speech rate, when instructed to accelerate, shows that significantly better acceleration was achieved by speakers in the former group compared with the latter. CONCLUSIONS: This study supports the finding that patients with Wilson's disease exhibit an impaired speech rate and also impaired control of speech rate. Indirect assessment of speech rate modulation with the help of a dual-task paradigm has proven to be useful to distinguish patient behaviors. This paradigm could also be envisioned as a tool for rehabilitation.

Impact of the COVID-19 pandemic on children and adolescents: determinants and association with quality of life and mental health-a cross-sectional study.

BACKGROUND: The medium-term impact of the COVID-19 pandemic on the wellbeing of children and adolescents remains unclear. More than 2 years into the pandemic, we aimed to quantify the frequency and determinants of having been severely impacted by the COVID-19 pandemic and estimate its impact on health-related quality of life (HRQoL) and mental health. METHODS: Data was drawn from a population-based cohort of children and adolescents, recruited between December 2021 and June 2022, in Geneva, Switzerland. The Coronavirus impact scale was used to assess the multidimensional impact of the pandemic on children through parent's report. A score higher than one standard deviation above the mean was deemed a severe impact. Parents additionally reported about their offspring HRQoL and mental health with validated scales. Determinants of having been severely impacted were assessed with logistic models, as were the associations between having experienced a severe impact and poor HRQoL or mental health. RESULTS: Out of 2101 participants aged 2-17, 12.7% had experienced a severe pandemic impact. Having a lasting health condition, a pandemic-related worsening of lifestyle habits or an unfavorable family environment were associated with having been severely impacted by the pandemic, while a previous anti-SARS-CoV-2 infection was not. Participants who had experienced a severe pandemic impact were more likely to present poor HRQoL (aOR = 3.1; 95% CI 2.3-4.4) and poor mental health (aOR = 3.9; 95% CI 2.5-6.2). CONCLUSION: The COVID-19 pandemic may have persistent consequences on the wellbeing of children and adolescents, especially among those with health and family vulnerabilities.

Socioeconomic conditions and children's mental health and quality of life during the COVID-19 pandemic: An intersectional analysis.

Background: Children and adolescents are highly vulnerable to the impact of sustained stressors during developmentally sensitive times. We investigated how demographic characteristics intersect with socioeconomic dimensions to shape the social patterning of quality of life and mental health in children and adolescents, two years into the COVID-19 pandemic. Methods: We used data from the prospective SEROCoV-KIDS cohort study of children and adolescents living in Geneva (Switzerland, 2022). We conducted an intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy by nesting participants within 48 social strata defined by intersecting sex, age, immigrant background, parental education and financial hardship in Bayesian multilevel logistic models for poor health-related quality of life (HRQoL, measured with PedsQL) and mental health difficulties (measured with the Strengths and Difficulties Questionnaire). Results: Among participants aged 2-17 years, 240/2096 (11.5%, 95%CI 10.1-12.9) had poor HRQoL and 105/2135 (4.9%, 95%CI 4.0-5.9) had mental health difficulties. The predicted proportion of poor HRQoL ranged from 3.4% for 6-11 years old Swiss girls with highly educated parents and no financial hardship to 34.6% for 12-17 years old non-Swiss girls with highly educated parents and financial hardship. Intersectional strata involving adolescents and financial hardship showed substantially worse HRQoL than their counterparts. Between-stratum variations in the predicted frequency of mental health difficulties were limited (range 4.4%-6.5%). Conclusions: We found considerable differences in adverse outcomes across social strata. Our results suggest that, post-pandemic, interventions to address social inequities in HRQoL should focus on specific intersectional strata involving adolescents and families experiencing financial hardship, while those aiming to improve mental health should target all children and adolescents.

Laparoscopic versus open approach for aortobifemoral bypass for severe aorto-iliac occlusive disease--a multicentre randomised controlled trial.

OBJECTIVES: To investigate differences between open and laparoscopic aortobifemoral bypass surgery for aorto-iliac occlusive disease on postoperative morbidity and mortality. DESIGN: A multicentre randomised controlled trial. METHODS: Between January 2007 and November 2009, 28 patients with severe aorto-iliac occlusive disease (TASC II C or D) were randomised between laparoscopic and open approach at one community hospital and one university hospital (TASC = Trans-Atlantic Inter-Society Consensus on the Management of Peripheral Arterial Disease). RESULTS: The operation time was longer for the laparoscopic approach (mean 4 h 19 min (2 h 00 min to 6 h 20 min) vs. 3 h 30 min (1 h 42 min to 5 h 11 min); p = 0.101)). Nevertheless, postoperative recovery and in-hospital stay were significantly shorter after laparoscopic surgery. Also oral intake could be restarted earlier (mean 20 h 34 min (6 h 00 min to 26 h 55 min) vs. 43 h 43 min (19 h 40 min to 77 h 30 min); p = 0.00014)) as well as postoperative mobilisation (walking) (mean 46 h 15 min (16 h 07 min to 112 h 40 min) vs. mean 94 h 14 min (66 h 10 min to 127 h 23 min); p = 0.00016)). Length of hospitalisation was shorter (mean 5.5 days (2.5-15) vs. mean 13.0 days (7-45); p = 0.0095)). Visual pain scores and visual discomfort scores were both lower after laparoscopic surgery. Also return to normal daily activities was achieved earlier. There were no major complications in both groups. CONCLUSION: Laparoscopic aortobifemoral bypass surgery for aorto-iliac occlusive disease is a safe procedure with a significant decrease in postoperative morbidity and in-hospital stay and earlier recovery.

Factor structure of borderline personality disorder symptomatology in adolescents.

OBJECTIVE: To examine the factor structure of the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, criteria for borderline personality disorder (BPD) in a sample of adolescents with a borderline symptomatology. METHOD: The latent structure of borderline criteria, assessed with the Structured Interview for DSM-IV Personality, was explored with a principal factor analysis in a sample of 107 adolescents with a borderline symptomatology drawn from a European research project on BPDs. RESULTS: The principal component analysis revealed 2 homogeneous factors accounting for 66.8% of the variance. The first factor included internally oriented criteria, such as avoidance of abandonment, identity disturbance, chronic feeling of emptiness, and stress-related paranoid ideation. The second factor included externally oriented criteria, such as unstable relationships, impulsivity, suicidal or self-mutilating behaviours, and inappropriate anger. Affective instability was the only criterion loading on both factors. CONCLUSIONS: The results of our study suggests that an internal or external dichotomy may be an appropriate way to conceptualize the structure of borderline criteria in adolescents with a borderline symptomatology, with affective instability being a core feature of BPD at this age.

Determinants of adolescents' Health-Related Quality of Life and psychological distress during the COVID-19 pandemic.

BACKGROUND: We examined the determinants of adolescents' Health-Related Quality of Life (HRQoL) and psychological distress (self-reported and parent-reported) during the COVID-19 pandemic, using a random sample of the population of Geneva, Switzerland. METHODS: Data was drawn from participants aged 14-17 years, who participated with their families to a serosurvey conducted in November and December 2020. Adolescents' HRQoL was evaluated using the validated adolescent-reported KIDSCREEN-10 and parent-reported KINDL® scales. Psychological distress was assessed with self-reported sadness and loneliness, and using the KINDL® emotional well-being scale. Using generalized estimating equations, we examined the role of socio-demographic, family and behavioural characteristics in influencing adolescents' mental health status and wellbeing. RESULTS: Among 240 adolescents, 11% had a low HRQoL, 35% reported sadness and 23% reported loneliness. Based on parents' perception, 12% of the adolescents had a low HRQoL and 16% a low emotional well-being. Being a girl (aOR = 3.20; 95%CI: 1.67-6.16), increased time on social media (aOR = 2.07; 95%CI: 1.08-3.97), parents' average to poor mood (aOR = 2.62; 95%CI: 1.10-6.23) and average to poor household financial situation (aOR = 2.31; IC95%: 1.01-6.10) were associated with an increased risk of sadness. Mismatches between adolescents' and their parents' perception of HRQoL were more likely for girls (aOR = 2.88; 95%CI: 1.54-5.41) and in households with lower family well-being (aOR = 0.91; 95%CI: 0.86-0.96). CONCLUSIONS: A meaningful proportion of adolescents experienced low well-being during the second wave of COVID-19, and average well-being was lower than pre-pandemic estimates. Adolescents living in underprivileged or distressed families seemed particularly affected. Monitoring is necessary to evaluate the long-term effects of the pandemic on adolescents.

A population-based serological study of post-COVID syndrome prevalence and risk factors in children and adolescents.

Post-COVID syndrome remains poorly studied in children and adolescents. Here, we aimed to investigate the prevalence and risk factors of pediatric post-COVID in a population-based sample, stratifying by serological status. Children from the SEROCoV-KIDS cohort study (State of Geneva, Switzerland), aged 6 months to 17 years, were tested for anti-SARS-CoV-2 N antibodies (December 2021-February 2022) and parents filled in a questionnaire on persistent symptoms in their children (lasting over 12 weeks) compatible with post-COVID. Of 1034 children tested, 570 (55.1%) were seropositive. The sex- and age-adjusted prevalence of persistent symptoms among seropositive children was 9.1% (95%CI: 6.7;11.8) and 5.0% (95%CI: 3.0;7.1) among seronegatives, with an adjusted prevalence difference (ΔaPrev) of 4.1% (95%CI: 1.1;7.3). Stratifying per age group, only adolescents displayed a substantial risk of having post-COVID symptoms (ΔaPrev = 8.3%, 95%CI: 3.5;13.5). Identified risk factors for post-COVID syndrome were older age, having a lower socioeconomic status and suffering from chronic health conditions, especially asthma. Our findings show that a significant proportion of seropositive children, particularly adolescents, experienced persistent COVID symptoms. While there is a need for further investigations, growing evidence of pediatric post-COVID urges early screening and primary care management.
