Study of the relationship between psychoactive substance use and pain in cancer patients and cancer survivors: A French nationwide cross-sectional study.

Pain is a prevalent symptom among cancer patients and survivors. Psychoactive substance use (PSU) is associated with both the presence and severity of pain. However, little is known about this association in the context of cancer. The primary objective was to compare the prevalence of PSU and its relationship with pain during and after cancer. PSU was defined as the use of nonmedication substances (alcohol, tobacco, e-cigarettes, cannabidiol, and cannabis), with frequency categorized as at least yearly, monthly, weekly, or daily. Secondary objectives aimed to explore the relationships between PSU and pain characteristics, health-related quality of life, anxiety, depression, deprivation, and individual characteristics. Among the 1041 individuals included, pain prevalence was 44.7% (95% confidence interval [CI] 41.6%-47.8%). The overall prevalence of PSU at least monthly was 67.0% (95% CI 64.0%-69.8%). The proportions of chronic and neuropathic pains were higher for at least monthly use of cannabidiol compared to nonuse (70.0% vs. 39.3% and 55.7% vs. 28.1%, p < .001). In multivariate analysis, the monthly uses of tobacco and cannabidiol were higher in painful individuals than in nonpainful ones (odds ratio: 2.85 [95% CI 1.22-6.64] and 3.76 [95% CI 1.13-12.44], p < .05). From the point of view of the patient care, the study underscores the need for physicians to prioritize smoking cessation and pay attention to the use of cannabidiol during and after cancer.

MISP Is Overexpressed in Intestinal Metaplasia and Gastric Cancer.

Gastric cancer is the fifth most common cancer and the fourth cause of global cancer mortality. The identification of new biomarkers and drug targets is crucial to allow the better prognosis and treatment of patients. The mitotic spindle positioning (MISP) protein has the function of correcting mitotic spindle positioning and centrosome clustering and has been implicated in the cytokinesis and migration of cancer cells. The goal of this work was to evaluate the expression and clinical relevance of MISP in gastric cancer. MISP expression was evaluated by immunohistochemistry in a single hospital series (n = 286) of gastric adenocarcinomas and compared with normal gastric mucosa and intestinal metaplasia, a preneoplastic lesion. MISP was detected on the membrane in 83% of the cases, being overexpressed in gastric cancer compared to normal gastric mucosa (n = 10). Its expression was negatively associated with diffuse and poorly cohesive types. On the other hand, it was strongly expressed in intestinal metaplasia where it was associated with MUC2 and CDX2 expression. Furthermore, when we silenced MISP in vitro, a significant decrease in the viability of gastric carcinoma cells was observed. In conclusion, MISP is overexpressed in gastric cancer, being associated with an intestinal phenotype in gastric carcinogenesis and having a role in cellular proliferation.

Effect of a peer-led prevention program (P2P) on smoking in vocational high school students: Results from a two-school-year cluster-randomized trial.

AIMS: The aim of this work was to measure the impact of P2P (i.e. peer-to-peer), a peer-led smoking prevention intervention, on daily smoking prevalence of adolescents over 2 school years. DESIGN: A cluster-randomized controlled trial was performed over a 16-month follow-up (trial status: closed to follow-up). P2P was implemented 1-3 and 13-15 months after baseline. Assessments took place at baseline and 4, 10 and 16 months after baseline. The research team, assessors and adolescents were blinded to the study-arm assignment only at baseline. SETTING: Fifteen vocational high schools in France were randomized into two clusters, using a 1:1 allocation ratio per French department (n intervention = 7, n control = 8). PARTICIPANTS: Participants comprised a sample of 2010 students in year 11 (i.e. 15-16 years) in vocational high schools. A total of 437 students could not be assessed at baseline (absent or left school), yielding a total sample of 1573 students (n intervention = 749, n control = 824). INTERVENTION AND COMPARATOR: The P2P programme trained voluntary students to become peer educators and design smoking prevention actions for their schoolmates in the intervention group (n = 945 students), compared with a passive control group (n = 1065 students). MEASUREMENTS: The primary outcome was change from baseline in the prevalence of self-reported daily smoking (i.e. at least one cigarette per day) at 16 months. FINDINGS: The 'time × group' interaction indicated that, compared with the control group, the intervention group had statistically significantly fewer daily smokers after 16 months [odds ratio (OR) = 0.33, 95% confidence interval (CI) = 0.20, 0.53]. Similarly, compared with the control group, the intervention group had statistically significantly fewer daily smokers after 4 months (OR = 0.50, 95% CI = 0.30, 0.82) and 10 months (OR = 0.60, 95% CI = 0.37, 0.98). No adverse events of P2P2 were reported. CONCLUSIONS: A cluster-randomized trial found evidence that the peer-led P2P (peer-to-peer) smoking prevention intervention reduced the uptake of daily smoking among high school students in France over 16 months.

The initial molecular response predicts the deep molecular response but not treatment-free remission maintenance in a real-world chronic myeloid leukemia cohort.

In chronic myeloid leukemia, the identification of early molecular predictors of stable treatment-free remission (TFR) after tyrosine kinase inhibitor (TKI) discontinuation is challenging. The predictive values of residual disease (BCR::ABL1 quantification) at months 3 and 6 and more recently, BCR::ABL1 transcript halving time (HT) have been described, but no study compared the predictive value of different early parameters. Using a real-world cohort of 408 patients, we compared the performance of the ELTS score, BCR::ABL1 HT, and residual disease at month 3 and 6 to predict the molecular response, achievement of the TKI discontinuation criteria, and TFR maintenance. The performances of BCR::ABL1 HT and residual disease at month 3 were similar. Residual disease at month 6 displayed the best performance for predicting the optimal response (area under the ROC curve between 0.81 and 0.92; cut-off values: 0.11% for MR4 at month 24 and 0.12% for MR4.5 at month 48). Conversely, no early parameter predicted reaching the TKI discontinuation criteria and TFR maintenance. We obtained similar results when patients were divided in subgroups by first-line treatment (imatinib vs second generation TKI, 2G-TKI). We identified a relationship between ELTS score, earlier milestones and TFR maintenance only in the 2G-TKI group. In conclusion, this first comparative study of early therapeutic response parameters showed that they are excellent indicators of TKI efficacy (BCR::ABL1 transcript reduction) and best responders. Conversely, they did not predict the achievement of the TKI discontinuation criteria and TFR maintenance, suggesting that other parameters are involved in TFR maintenance.

Neoadjuvant Chemotherapy Does Not Improve Survival in cT2N0M0 Gastric Adenocarcinoma Patients: A Multicenter Propensity Score Analysis.

BACKGROUND: According to current international guidelines, stage cT2N0M0 gastric adenocarcinoma warrants preoperative chemotherapy followed by surgery. However, upfront surgery is often preferred in clinical practice, depending on patient clinical status and local treatment preferences. OBJECTIVE: The aim of the present study was to assess the impact of neoadjuvant chemotherapy in overall survival (OS) and disease-free survival (DFS) of cT2N0M0 patients. METHODS: A retrospective analysis was performed among 32 centers, including gastric adenocarcinoma patients operated between January 2007 and December 2017. Patients with cT2N0M0 stage were divided into upfront surgery (S) and neoadjuvant chemotherapy followed by surgery (CS) groups. Inverse probability of treatment weighting (IPTW) was used to compensate for baseline differences between the groups. RESULTS: Among the 202 patients diagnosed with cT2N0M0 stage, 68 (33.7%) were in the CS group and 134 (66.3%) were in the S group. CS patients were younger (mean age 62.7 ± 12.8 vs. 69.8 ± 12.1 years for S patients; p < 0.001) and had a better health status (World Health Organization performance status = 0 in 60.3% of CS patients vs. 34.5% of S patients; p = 0.006). During follow-up, recurrence occurred in 27.2% and 19.6% of CS and S patients, respectively, after IPTW (p = 0.32). Five-year OS was similar between CS and S patients (78.9% vs. 68.3%; p = 0.42), as was 5-year DFS (70.4% vs. 68.5%; p = 0.96). Neoadjuvant chemotherapy was associated with neither OS nor DFS in multivariable analysis after IPTW. CONCLUSIONS: Patients with cT2N0M0 gastric adenocarcinoma did not present a survival or recurrence benefit if treated with perioperative chemotherapy followed by surgery as opposed to surgery alone.

Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago.

BACKGROUND: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. METHODS: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. RESULTS: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. CONCLUSIONS: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception.

Comparison of self-management and spa therapy for upper-extremity musculoskeletal disorders: A randomized controlled trial.

BACKGROUND: Musculoskeletal disorders (MSDs) are common in the workplace and are a public health issue. Persistent pain despite conservative treatment or surgery may lead to poor long-term outcomes. OBJECTIVE: To compare the effect of a combined 6-day program of exercise, self-management workshops and spa therapy with self-management on functional capacity in personal and professional daily life at 3 months in people with musculoskeletal disorders. METHODS: We conducted a prospective, randomized controlled trial. Participants were employed (any type of work) and aged between 18 and 65 years, with latent or symptomatic upper extremity MSDs, with or without a history of sick leave. They were randomized to participate in 6 days (2 h per day) of spa therapy, exercise, and self-management workshops immediately (intervention) or at 3 months (control). The control group performed self-management until 3 months. The primary outcome was the score on the self-reported Quick Disability of Arm-Shoulder-Hand (QuickDASH) at 3 months. The primary analysis was conducted using analysis of covariance with baseline QuickDASH score as the covariate. RESULTS: In total, 150 participants were randomized (85 % women): 78 to the control group and 72 to the intervention group. At 3 months, the QuickDASH total and work scores did not differ between groups (effect-size [ES] = -0.15, 95 %CI, -0.38 to 0.09, p = 0.215, and ES = -0.11, 95 % CI, -0.35 to 0.12, p = 0.343). However, QuickDASH sport/performing arts score was significantly different between randomization groups at 3 months (ES =-0.25, 95 % CI, -0.48 to -0.02, p = 0.035). CONCLUSIONS: This study provided no evidence in favor of a short-course, personalized self-management, intensive spa therapy intervention over self-management alone for the management of upper-extremity MSDs. TRIAL REGISTRATION: ClinicalTrials.gov (NCT02702466) retrospectively registered.

Meta-analysis of randomized clinical trials comparing robotic versus laparoscopic surgery for mid-low rectal cancers.

INTRODUCTION: Robotic surgery (RS) is experiencing major development, particularly in the context of rectal cancer. The aim of this meta-analysis was to summarize data from the literature, focusing specifically on the safety and effectiveness of robotic surgery in mid-low rectal cancers, based on the hypothesis that that robotic surgery can find its most rational indication in this anatomical location. METHOD: The meta-analysis was conducted according to the PRISMA 2000 recommendations, including all randomized trials that compared robotic surgery versus laparoscopic surgery (LS) that were found in the Medline-PICO, Cochrane Database, Scopus and Google databases. Data were extracted independently by two reviewers. The risk of bias was analyzed according to the Cochrane Handbook method and the certainty of the evidence according to the GRADE method. The analysis was carried out with R software Version 4.2-3 using the Package for Meta-Analysis "meta" version 6.5-0. RESULTS: Eight randomized trials were included (with a total of 2342 patients), including four that focused specifically on mid-low rectal cancer (n=1,734 patients). No statistically significant difference was found for overall morbidity, intra-operative morbidity, anastomotic leakage, post-operative mortality, quality of mesorectal specimen, and resection margins. The main differences identified were a lower conversion rate for RS (RR=0.48 [0.24-0.95], p=0.04, I2=0%), and a longer operative time for RS (mean difference=39.11min [9.39-68.83], p<0.01, I2=96%). The other differences had no real clinical relevance, i.e., resumption of flatus passage (5hours earlier after RS), and lymph node dissection (one more lymph node for LS). CONCLUSION: This meta-analysis does not confirm the initial hypothesis and does not show a statistically significant or clinically relevant benefit of RS compared to LS for mid-low rectal cancer.

Augmented Reality Guided Laparoscopic Liver Resection: A Phantom Study With Intraparenchymal Tumors.

INTRODUCTION: Augmented reality (AR) in laparoscopic liver resection (LLR) can improve intrahepatic navigation by creating a virtual liver transparency. Our team has recently developed Hepataug, an AR software that projects the invisible intrahepatic tumors onto the laparoscopic images and allows the surgeon to localize them precisely. However, the accuracy of registration according to the location and size of the tumors, as well as the influence of the projection axis, have never been measured. The aim of this work was to measure the three-dimensional (3D) tumor prediction error of Hepataug. METHODS: Eight 3D virtual livers were created from the computed tomography scan of a healthy human liver. Reference markers with known coordinates were virtually placed on the anterior surface. The virtual livers were then deformed and 3D printed, forming 3D liver phantoms. After placing each 3D phantom inside a pelvitrainer, registration allowed Hepataug to project virtual tumors along two axes: the laparoscope axis and the operator port axis. The surgeons had to point the center of eight virtual tumors per liver with a pointing tool whose coordinates were precisely calculated. RESULTS: We obtained 128 pointing experiments. The average pointing error was 29.4 ± 17.1 mm and 9.2 ± 5.1 mm for the laparoscope and operator port axes respectively (P = 0.001). The pointing errors tended to increase with tumor depth (correlation coefficients greater than 0.5 with P < 0.001). There was no significant dependency of the pointing error on the tumor size for both projection axes. CONCLUSIONS: Tumor visualization by projection toward the operating port improves the accuracy of AR guidance and partially solves the problem of the two-dimensional visual interface of monocular laparoscopy. Despite a lower precision of AR for tumors located in the posterior part of the liver, it could allow the surgeons to access these lesions without completely mobilizing the liver, hence decreasing the surgical trauma.

Eicosanoids and oxylipin signature in HH patients are similar to DIOS patients but are impacted by dietary iron absorption.

INTRODUCTION: Oxylipins are mediators of oxidative stress. To characterize the underlying inflammatory processes and phenotype the effect of iron metabolism disorders, we investigated the oxylipin profile in hereditary hemochromatosis (HH) and dysmetabolic iron overload syndrome (DIOS) patients. METHODS: LC-MS/MS based method to quantify plasma oxylipins in 20 HH and 20 DIOS patients in fasting conditions and 3 hours after an iron-rich meal in HH patients. RESULTS: Principal component analysis showed no separation between HH and DIOS, suggesting that the clinical phenotype has no direct impact on oxylipin metabolism. 20-HETE was higher in DIOS and correlated with hypertension (p = 0.03). Different oxylipin signatures were observed in HH before and after the iron-rich meal. Discriminant oxylipins include epoxy fatty acids derived from docosahexaenoic acid and arachidonic acid as well as 13-HODE and 9-HODE. Mediation analysis found no major contribution of dietary iron absorption for 16/22 oxylipins significantly affected by the meal. DISCUSSION: The oxylipin profiles of HH and DIOS seemed similar except for 20-HETE, possibly reflecting different hypertension prevalence between the two groups. Oxylipins were significantly affected by the iron-rich meal but the specific contribution of iron was not clear. Although iron may contribute to oxidative stress and inflammation in HH and DIOS, this does not seem to directly affect oxylipin metabolism.

Embryotoxic Effects of Pesticides in Zebrafish (Danio rerio): Diflubenzuron, Pyriproxyfen, and Its Mixtures.

Diflubenzuron (DFB) and pyriproxyfen (PPF) are larvicides used in crops to control insect plagues. However, these pesticides are known to impact non-target organisms like fish and mammals. Here, we aimed at assessing the embryotoxicity of purified DFB, PPF, and their mixtures in a non-target organism-zebrafish. Zebrafish embryos were exposed to different concentrations for 120 h: 0.025, 0.125, 0.25, 1.25, 2.5, and 10 mg/L of purified PPF and purified DFB, while we used 0.025 mg/L PPF + 10 mg/L DFB (Mix A), 0.125 mg/L PPF + 10 mg/L DFB (Mix B), and 0.25 mg/L PPF + 10 mg/L DFB (Mix C) for the mixtures of PPF + DFB. We observed mortality, teratogenicity, and cardiotoxicity. For the neurotoxicity tests and evaluation of reactive oxygen species (ROS) levels in the brain, embryos were exposed for 120 h to 0.379 and 0.754 mg/L of PPF and 0.025 and 0.125 mg/L of DFB. We established the LC50 for PPF as 3.79 mg/L, while the LC50 for DFB was not determinable. Survival and hatching were affected by PPF concentrations above 0.125 mg/L, DFB concentrations above 1.25 mg/L, and the lower pesticide mixtures. PPF exposure and mixtures induced different types of malformations, while a higher number of malformations were observed for the mixtures, suggesting a potentiating effect. Pesticides diminished avoidance responses and increased the levels of ROS across all concentrations, indicating neurotoxicity. Our findings underscore the detrimental impact of PPF and DFB exposure, spanning from biochemistry to morphology. There is a critical need to reconsider the global use of these pesticides and transition to more ecologically friendly forms of pest control, raising an alarm regarding repercussions on human and animal health and well-being.

CX3CL1/Fractalkine as a biomarker for early pregnancy prediction of preterm premature rupture of membranes.

OBJECTIVES: The objective of our study was to evaluate serum CX3CL1/Fractalkine, a monocyte/macrophage chemoattractant expressed in cytotrophoblasts and decidual cells, as a predictive biomarker for the occurrence of preterm premature rupture of membranes (PPROM). METHODS: A case-control study of 438 pregnancies including 82 PPROM cases and 64 preterm labor with intact membranes cases with blood samples collected at first trimester, second trimester and delivery was conducted. The predictive ability of CX3CL1 and maternal risk factors for the occurrence of PPROM was assessed by receiver operating characteristic curve analysis. A second, independent cohort was prospectively constituted to confirm the case-control study results. RESULTS: First trimester CX3CL1 was significantly increased in PPROM cases when compared to matched controls. Multivariate regression analysis highlighted a significant difference for CX3CL1 measured during the first trimester (p<0.001). Alone, CX3CL1 predicts PPROM with a 90 % sensitivity and a specificity around 40 %. The area under the receiver operating characteristic curve for PPROM prediction were 0.64 (95% confidence interval: 0.57-0.71) for first trimester CX3CL1, and 0.61 (95% confidence interval: 0.54-0.68) for maternal risk factors (body mass index<18.5 kg/m2, nulliparity, tobacco use and the absence of high school diploma). The combination of CX3CL1 and maternal risk factors significantly improved the area under the curve: 0.72 (95% confidence interval: 0.66-0.79) (p<0.001). The results were confirmed on a second independent cohort. CONCLUSIONS: CX3CL1 is a promising blood biomarker in the early (first trimester) prediction of PPROM.

Salvage cryotherapy for prostate cancer.

BACKGROUND: Most men diagnosed with prostate cancer will be candidates for active treatment and 20 to 50% of patients treated with organ preserving strategies recur within the prostate. Optimal treatment of recurrence is controversial. Prostate cryosurgery has been increasingly used as primary, recurrence and focal treatment for prostate cancer. METHODS: We analysed 55 patients submitted to cryotherapy as salvage treatment after recurrence. RESULTS: Study population presented with a mean age of 70.9 ± 6.2 years, mean initial PSA of 7.6 ng/ml and average prostate volume by ultrasound of 43.2 ± 14.7 grams. Mean follow-up was of 18.0 months. Biochemical free survival at one year of follow-up was of 85%. CONCLUSIONS: Cryotherapy can be an effective and safe treatment for recurrence after primary curative treatment failure.

[Obstetrical outcome of renal transplant patients followed in a type III maternity hospital. Retrospective study from 2000 to 2020]. / Devenir obstétrical des patientes transplantées rénales suivies dans une maternité de type III. Étude rétrospective de 2000 à 2020.

AIM: To describe pregnancy outcome of kidney transplant patients till 1 year postpartum. METHODS: This retrospective, monocentric study included 15 kidney transplant patients who presented 18 pregnancies, between January 2000 and January 2020. For each of them, we searched for possible obstetrical, fetal and renal complications and we evaluated renal function before, during and after pregnancy. RESULTS: The live birth rate was 84% (16/19) with an average gestational age at delivery of 37 weeks of gestation. The rate of prematurity was 50% (8/16), gestational diabetes was 16.6% (3/18) and preeclampsia was 27.7% (5/18). Cesarean section was performed in 61.1% (11/18) of cases including, 81.8% (9/11) unplanned surgery. The average birth weight was 2635 grams and 37.5% (6/16) of the newborn were small for gestational age. All patients had stable renal function before conception of pregnancy. We noticed two acute graft rejection during pregnancy with only one resulting in graft loss. Four patients had a reduced graft function in 12months of the postpartum. CONCLUSION: Risk of maternal, fetal and renal complications remained high in kidney transplant recipients. Pregnancy should be carefully planned in transplanted women associated with adequate follow-up according to clinical guidelines (normal renal function and blood pressure without proteinuria before pregnancy, no recent graft rejection, period of one year after transplant respected and no teratogenic treatment in the month before pregnancy).

Prevalence of FGF23 elevation in patients with hypophosphatemia.

BACKGROUND AND AIMS: To investigate the contribution of FGF23 in explaining the cases of hypophosphatemia observed in clinical practice, we aimed to determine for the first time the prevalence of FGF23 elevation in patients with hypophosphatemia and to describe the different mechanisms of FGF23-related hypophosphatemic disorders. MATERIALS AND METHODS: We performed a prospective, observational, multicenter, cohort study of 260 patients with hypophosphatemia. Blood measurements (PTH, 1,25-dihydroxyvitamin D, bone alkaline phosphatase, 25-hydroxyvitamin D, and FGF23) were performed on a Liaison XL® (DiaSorin) analyzer. RESULTS: Primary elevation of FGF23 (>95.4 pg/mL) was reported in 10.4% (95CI: 7.0-14.7) of patients (n = 27) with hypophosphatemia, suggesting that at least 1 in 10 cases of hypophosphatemia was erroneously attributed to an etiology other than FGF23 elevation. Patients with elevated blood FGF23 were grouped according to the etiology of the FGF23 elevation. Thus, 10 patients had a renal pathology, chronic kidney disease or post-renal transplantation condition. The remaining patients (n = 17) had the following etiologies: malignancies (n = 9), benign pancreatic tumor (n = 1), post-cardiac surgery (n = 4), cirrhosis (n = 2), and chronic obstructive pulmonary disease (n = 1). CONCLUSION: In order to improve patient management, it seems essential to better integrate plasma FGF23 measurement into the routine evaluation of hypophosphatemia.

Impact of screening programme to prevent anal cancer in high-risk patients with HIV.

INTRODUCTION: We assessed the impact of a nationwide screening programme to reduce the risk of anal cancer in a large cohort of high-risk patients with HIV. METHODS: From a large database from one referral centre, all high-risk patients with HIV (men who have sex with men, history of anal or genital warts, or previous cervix human papillomavirus-related lesions) who were eligible to enter the French anal cancer screening programme (2011-2020) were retrospectively included. Adherence to the screening programme was defined as no interval >18 months between two visits. Standardized management included perianal visualization and standard anoscopy with biopsies of macroscopic abnormalities. RESULTS: Overall, 700 patients with HIV were included (median follow-up 8.4 years [interquartile range 4.3-9.2] and 1491.6 patient-years), and 336 had one or more proctology visit. A total of 13 patients were diagnosed with anal squamous cell carcinomas. The risk of anal cancer was higher with anal intra-epithelial neoplasia grade 3 (AIN3; hazard ratio [HR] 44.5 [95% confidence interval {CI} 11.2-176.6], p < 0.001), AIN2 (HR 11.9 [95% CI 2.1-66.9], p = 0.005), or high-grade dysplasia (HR 23.4 [95% CI 7.9-69.1], p < 0.001) than with low-grade dysplasia or no lesion. Among the patients who were strictly adherent to the screening programme (4.6% [32/700]), we did not report any AIN or anal cancer, but we also did not observe any significant reduction in the risk of anal cancer (p = 0.51), AIN3 (p = 0.28), high-grade dysplasia (p = 0.19), or any AIN lesions (p = 0.10) compared with non-adherent patients. In contrast, screened patients were more likely to be diagnosed with anal warts (HR 3.71 [95% CI 2.14-6.42], p < 0.001). CONCLUSION: Macroscopic high-grade dysplasia lesions are associated with a higher risk of developing anal cancer. Despite finding no cases of cancer during the screening programme, we also did not demonstrate a clear benefit from our screening programme for the prevention of anal cancer in high-risk patients with HIV.

Total Versus Subtotal Gastrectomy for Distal Gastric Poorly Cohesive Carcinoma.

BACKGROUND: Gastric poorly cohesive carcinoma (PCC) in advanced stages has a poor prognosis. Total gastrectomy (TG) remains the common treatment for distal gastric PCC, but subtotal gastrectomy (SG) may improve quality of life without compromising outcomes. Currently, no clear recommendation on the best surgical strategy for distal PCC is available. This study aimed to compare overall survival (OS) and disease-free survival (DFS) at 5 years for patients with antropyloric PCC treated by total versus subtotal gastrectomy. METHODS: A large retrospective European multicenter cohort study analyzed 2131 patients treated for gastric cancer between 2007 and 2017 by members of the French Association of Surgery (AFC). The study compared a group of patients who underwent TG with a group who underwent SG for antropyloric PCC. The primary outcomes were 5 year OS and DFS. RESULTS: The study enrolled 269 patients: 140 (52.0%) in the TG group and 129 (48.0%) in the SG group. The baseline characteristics and pTNM stage were similar between the two groups. According to Dindo-Claven classification, the patients treated with TG had more postoperative complications than the patients treated with SG (p < 0.001): grades I to IIIa (77.1% vs 59.5%) and grades IIIb to IVb (14.4% vs 9.0%). No difference in 5-year OS was observed between TG (53.8%; 95 % confidence interval [CI], 43.2-63.3%) and SG (53.0%; 95% CI, 41.4-63.3%) (hazard ratio [HR], 0.94; 95% CI, 0.68-1.29). The same was observed for 5-year DFS: TG (46.0%; 95% CI, 35.9-55.5%) versus SG (45.3%; 95% CI, 34.3-55.6%) (HR, 0.97; 95% CI, 0.70-1.34). CONCLUSIONS: At 5 years, SG was not associated with worse OS and DFS than TG for distal PCC. Surgical morbidity was higher after TG. Subtotal gastrectomy is a valuable option for distal PCC gastric cancer.

Thyroid dysfunction alters gene expression of proteins related to iron homeostasis and metabolomics in male rats.

Thyroid hormones (THs) are crucial in bodily functions, while iron is essential for processes like oxygen transport. Specialized proteins maintain iron balance, including ferritin, transferrin, ferroportin, and hepcidin. Research suggests that THs can influence iron homeostasis by affecting mRNA and protein expression, such as ferritin and transferrin. Our study focused on male rats to assess mRNA expression of iron homeostasis-related proteins and metabolomics in thyroid dysfunction. We found altered gene expression across various tissues (liver, duodenum, spleen, and kidney) and identified disrupted metabolite patterns in thyroid dysfunction. These findings highlight tissue-specific effects of thyroid dysfunction on essential iron homeostasis proteins and provide insights into associated metabolic changes. Our research contributes to understanding the intricate interplay between thyroid hormones and iron balance. By unveiling tissue-specific gene expression alterations and metabolic disruptions caused by thyroid dysfunction, our work lays a foundation for future investigations to explore underlying mechanisms and develop targeted strategies for managing iron-related complications in thyroid disorders.

Early detection of pharyngocutaneous fistulae after total laryngectomy by cytokine in drainage: A pilot study (DEFILAC).

BACKGROUND: The determination of cytokines in the postoperative drainage (POD) fluid could be a method for early detection of the development of a pharyngocutaneous fistula (PCF). MATERIALS AND METHODS: We conducted a prospective two-center study involving 28 patients. PODs were collected on Day 1 (D1) and Day 2 (D2) postoperatively for determination of a cytokine panel and cytobacteriological examination. RESULTS: Eleven (39%) patients presented with PCF on average 13 ± 5.5 days after surgery. Patients with PCF had higher IL-10 (121 vs. 40.3, p = 0.04, effect size (ES) = 0.98 [0.16, 1.79]) and TNFα level (21.2 vs. 2.2, p = 0.02, ES = 0.83 [0.03, 1.63]) on D2. An IL-10 threshold of 72 pg/mL on D2 was diagnostic of the occurrence of PCF with a sensibility of 70%, specificity of 88%. CONCLUSION: The determination of cytokines in POD fluid on D2 is a reliable tool for predicting the development of a PCF after total laryngectomy.
