Background Methods Results Conclusions Assessing the potential increased risk of viral rebound (VR) in migrants requires adequate control for sex and acquisition risk groups.People living with HIV1, enrolled in the ANRS CO4‐French Hospital Database on HIV, who achieved virological suppression with antiretroviral therapy (ART) initiated between 2006 and 2016 were included. We first compared the risk of VR, with loss to follow‐up and death considered as competing events, across origin among the HIV acquisition groups, then across acquisition groups among the different origins, and finally across modality of a variable combining sex, acquisition group, and origin. Models were adjusted for clinical and biological confounding factors.We included 21 571 French natives (FRA), 10 148 migrants from sub‐Saharan Africa (SSA), 1137 migrants from the non‐French West Indies (NFWI), and 4205 other migrants (OTHER). The 5‐year probability of VR was 19% (95% confidence interval [CI] 19–20) overall, 15% in FRA, 21% in OTHER, 26% in SSA, and 34% in NFWI (p < 0.0001). It was 14% in men who have sex with men (MSM), 23% in heterosexual men, and 23% in women (p < 0.0001). After adjustment, all acquisition groups had a higher risk of VR than MSM from FRA, with men and women from NFWI having the highest risk (adjusted hazard ratio [aHR] 2.46; 95% CI 2.12–2.86 and aHR 2.59; 95% CI 2.20–3.04, respectively). Within each acquisition group, all groups of origin had a higher risk of VR than FRA. Within each region of origin, except the NFWI, heterosexual men had a higher risk of VR than MSM.After accounting for sex and acquisition group, migration, especially from NFWI, remains prognostic of VR.

Background: Despite evidence of benefits on postoperative outcomes, minimally invasive liver surgery (MILS) had a very low diffusion up to 2014, and recent evolution is unknown. Our aim was to analyze the recent diffusion and adoption of MILS and compare the trends in indications, extent of resection, and institutional practice with open liver surgery (OLS)., Methods: We analyzed the French nationwide, exhaustive cohort of all patients undergoing a liver resection in France between January 1, 2013 and December 31, 2022. Average annual percentage changes (AAPC) in the incidence of MILS and OLS were compared using mixed-effects log-linear regression models. Time trends were analyzed in terms of extent of resection, indication, and institutional practice., Results: MILS represented 25.2% of 74,671 liver resections and year incidence doubled from 16.5% in 2013 to 35.4% in 2022. The highest AAPC were observed among major liver resections [+ 22.2% (19.5; 24.9) per year], primary [+ 10.2% (8.5; 12.0) per year], and secondary malignant tumors [+ 9.9% (8.2; 11.6) per year]. The highest increase in MILS was observed in university hospitals [+ 14.7% (7.7; 22.2) per year] performing 48.8% of MILS and in very high-volume (> 150 procedures/year) hospitals [+ 12.1% (9.0; 15.3) per year] performing 19.7% of MILS. OLS AAPC decreased for all indications and institutions and accelerated over time from - 1.8% (- 3.9; - 0.3) per year in 2013-2018 to - 5.9% (- 7.9; - 3.9) per year in 2018-2022 (p = 0.013)., Conclusions: This is the first reported trend reversal between MILS and OLS. MILS has considerably increased at a national scale, crossing the 20% tipping point of adoption rate as defined by the IDEAL framework., (© 2024.

Objective: It is unknown whether hepatitis C virus (HCV)-cured people with HIV (PWH) without cirrhosis reached the same mortality risk as HCV-uninfected PWH. We aimed to compare mortality in PWH cured of HCV by direct-acting antivirals (DAAs) to mortality in individuals with HIV monoinfection., Design: Nationwide hospital cohort., Methods: HIV-controlled participants without cirrhosis and HCV-cured by DAAs started between September 2013 and September 2020, were matched on age (±5 years), sex, HIV transmission group, AIDS status, and body mass index (BMI) (±1 kg/m 2 ) to up to 10 participants with a virally suppressed HIV monoinfection followed at the time of HCV cure ±6 months. Poisson regression models with robust variance estimates were used to compare mortality in both groups after adjusting for confounders., Results: The analysis included 3961 HCV-cured PWH (G1) and 33 872 HCV-uninfected PWH (G2). Median follow-up was 3.7 years in G1 [interquartile range (IQR): 2.0-4.6], and 3.3 years (IQR: 1.7-4.4) in G2. Median age was 52.0 years (IQR: 47.0-56.0), and 29 116 (77.0%) were men. There were 150 deaths in G1 [adjusted incidence rate (aIR): 12.2/1000 person-years] and 509 (aIR: 6.3/1000 person-years) in G2, with an incidence rate ratio (IRR): 1.9 [95% confidence interval (CI), 1.4-2.7]. The risk remained elevated 12 months post HCV cure (IRR: 2.4 [95% CI, 1.6-3.5]). Non-AIDS/non-liver-related malignancy was the most common cause of death in G1 (28 deaths)., Conclusions: Despite HCV cure and HIV viral suppression, after controlling on factors related to mortality, DAA-cured PWH without cirrhosis remain at higher risk of all-cause mortality than people with HIV monoinfection. A better understanding of the determinants of mortality is needed in this population., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Introduction: Association of high body mass index (BMI) with longer survival has been reported in patients on immune checkpoint inhibitors (ICIs), but results are inconsistent. This 'obesity paradox' is potentially confounded by the effects of BMI change over time and of skeletal muscle depletion., Methods: We conducted a secondary analysis of a prospective cohort, including consecutive patients receiving ICI treatment for melanoma (n = 411) and non-small cell lung cancer (NSCLC) (n = 389) in routine care., Results: In the univariable analysis of the entire population, overweight/obesity (BMI ≥ 25 kg/m 2 ) was associated with longer survival (p < 0.01); however, this effect was limited to NSCLC (p < 0.01) and was absent in melanoma. Weight loss (WL) and reduced skeletal muscle mass were observed in patients within all BMI categories. WL was associated with shorter survival in multivariable analysis in both tumour sites (p < 0.01), and for NSCLC, BMI lost significance when WL was included (p = 0.13). In models further adjusted for CT-defined skeletal muscle mass, WL retained significance for both tumour types (p < 0.01), and reduced skeletal muscle only for NSCLC (p = 0.02) was associated with shorter survival. WL retained significance when biomarkers (lactate dehydrogenase enzyme, albumin and derived neutrophil to lymphocyte ratio) were added to the multivariable model., Conclusions: The so-called 'obesity paradox', counterintuitive association between high BMI and longer survival, vanished when controlling for confounders, such as type of cancer, and manifestations of depletion (WL and reduced skeletal muscle mass)., Competing Interests: Conflict of interest statement The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Pr Robert reported consultant advisory for BMS, Novartis, MSD, AstraZeneca, Pierre Fabre, Sanofi, Roche and co-founder of Robonexus outside submitted work.

Background: The impact of weight loss induced by bariatric surgery on cancer occurrence is controversial. To study the causal effect of bariatric surgery on cancer risk from an observational database, a target-trial emulation technique was used to mimic an RCT., Methods: Data on patients admitted between 2010 and 2019 with a diagnosis of obesity were extracted from a national hospital discharge database. Criteria for inclusion included eligibility criteria for bariatric surgery and the absence of cancer in the 2 years following inclusion. The intervention arms were bariatric surgery versus no surgery. Outcomes were the occurrence of any cancer and obesity-related cancer; cancers not related to obesity were used as negative controls., Results: A total of 1 140 347 patients eligible for bariatric surgery were included in the study. Some 288 604 patients (25.3 per cent) underwent bariatric surgery. A total of 48 411 cancers were identified, including 4483 in surgical patients and 43 928 among patients who did not receive bariatric surgery. Bariatric surgery was associated with a decrease in the risk of obesity-related cancer (hazard ratio (HR) 0.89, 95 per cent c.i. 0.83 to 0.95), whereas no significant effect of surgery was identified with regard to cancers not related to obesity (HR 0.96, 0.91 to 1.01)., Conclusion: When emulating a target trial from observational data, a reduction of 11 per cent in obesity-related cancer was found after bariatric surgery., (© The Author(s) 2022.

Patients with hematological malignancy and COVID-19 display a high mortality rate. In such patients, immunosuppression due to underlying disease and previous specific treatments impair humoral response, limiting viral clearance. Thus, COVID-19 convalescent plasma (CCP) therapy appears as a promising approach through the transfer of neutralizing antibodies specific to SARS-CoV-2. We report the effect of CCP in a cohort of 112 patients with hematological malignancy and COVID-19 and a propensity score analysis on subgroups of patients with B-cell lymphoid disease treated (n = 81) or not (n = 120) with CCP between May 1, 2020 and April 1, 2021. The overall survival of the whole cohort was 65% (95% CI = 56-74.9) and 77.5% (95% CI = 68.5-87.7) for patients with B-cell neoplasm. Prior anti-CD20 monoclonal antibody therapy was associated with better overall survival, whereas age, high blood pressure, and COVID-19 severity were associated with a poor outcome. After an inverse probability of treatment weighting approach, we observed in anti-CD20-exposed patients with B-cell lymphoid disease a decreased mortality of 63% (95% CI = 31-80) in the CCP-treated group compared to the CCP-untreated subgroup, confirmed in the other sensitivity analyses. Convalescent plasma may be beneficial in COVID-19 patients with B-cell neoplasm who are unable to mount a humoral immune response., (© 2022.

Background: Antibiotic consumption has been reported to be driven by the treatment of respiratory tract infections. Our objectives were to describe the trend of antibiotic consumption in France compared with that of other European countries; to describe the evolution of each antibiotic class in France; and to explore the relationship between antibiotic consumption and incidence of influenza-like illnesses., Methods: In this observational study, antibiotic consumption was reported as defined daily doses per 1000 inhabitants per day in the community and hospital sectors in descriptive and graphical formats, using data from the European Surveillance of Antimicrobial Consumption Network database. The total consumption and the consumption of different classes of antibiotics in France according to time and influenza-like illnesses were studied using multiple linear regression models., Results: The total consumption of antibiotics in France was constant over the 15 years. It was driven by the community sector (92.8%) and was higher than the consumption of other European Union countries (P-value < 0.001). The beta-lactam penicillins were the most consumed antibiotic class and the only class that increased with time. The multiple linear regression models showed a positive correlation between antibiotic consumption in the community sector and incidence of influenza-like illnesses [B = 0.170, 95% CI (0.088-0.252)]. Similar significant results were shown between other antibiotic classes used in the management of influenza-like illnesses (other beta-lactams, and macrolides, lincosamides and streptogramins) and influenza-like illnesses., Conclusion: Our results suggest that antibiotics used in the management of respiratory tract infections might be involved in the irrational use of antibiotics., (© The Author(s) 2021.
