RÉSUMÉ

BACKGROUND: Autologous mesenchymal stem cells (MSCs) have emerged as a therapeutic option for many diseases. Hypertensive kidney disease (HKD) might impair MSCs' reparative ability by altering the biomolecular properties, but the characteristics of this impairment are unclear. In our previous pre-clinical studies, we found hypoxic preconditioning (HPC) enhanced angiogenesis and suppressed senescence gene expression. Thus, we hypothesize that HPC would improve human MSCs by enhancing their functionality and angiogenesis, creating an anti-inflammatory and anti-senescence environment. METHODS: MSC samples (n = 12 each) were collected from the abdominal fat of healthy kidney donors (HC), hypertensive patients (HTN), and patients with hypertensive kidney disease (HKD). MSCs were harvested and cultured in Normoxic (20% O2) or Hypoxic (1% O2) conditions. MSC functionality was measured by proliferation assays and cytokine released in conditioned media. Senescence was evaluated by senescence-associated beta-galactosidase (SA-beta-gal) activity. Additionally, transcriptome analysis using RNA-sequencing and quantitative PCR (qPCR) were performed. RESULTS: At baseline, normoxic HTN-MSCs had higher proliferation capacity compared to HC. However, HPC augmented proliferation in HC. HPC did not affect the release of pro-angiogenic protein VEGF, but increased EGF in HC-MSC, and decreased HGF in HC and HKD MSCs. Under HPC, SA-ß-gal activity tended to decrease, particularly in HC group. HPC upregulated mostly the pro-angiogenic and inflammatory genes in HC and HKD and a few senescence genes in HKD. CONCLUSIONS: HPC has a more favorable functional effect on HC- than on HKD-MSC, reflected in increased proliferation and EGF release, and modest decrease in senescence, whereas it has little effect on HTN or HKD MSCs.

RÉSUMÉ

Objective: To investigate the impact of gallbladder cholesterolosis on the morphology of gallstones. Methods: The patients with gallstone who underwent cholecystectomy at the Gallstone Disease Center of East Hospital Affiliated to Tongjin University from December 2020 to October 2021 were retrospectively included. The patients were divided into the case group (sludge-like) and the control group (non-sludge-like stone), based on gallstone morphology. Clinical baseline characteristics between the two groups were compared. The related factors influencing gallstone morphology were analyzed using multivariate logistic regression analysis. Results: A total of 110 patients were included, with 30 cases in the case group (13 males, 17 females), aged 26-73 (54±14) years, 80 cases in the control group (24 males, 56 females), aged 18-75 (45±13) years. The age of the case group was higher than that of the control group (P=0.003). The occurrence rate of occult pancreaticobiliary reflux (OPBR) was higher in the case group compared to the control group [33.3% (10/30) vs 13.8% (11/80), P=0.020]; the occurrence rate of gallbladder cholesterolosis was lower in the case group compared to the control group [30.0% (9/30) vs 73.8% (59/80), P<0.001]. The results of multivariate logistic regression analysis showed that gallbladder cholesterolosis (OR=0.19, 95%CI: 0.07-0.49, P=0.001) was a significant factor associated with sludge-like stones. Conclusion: Gallbladder cholesterolosis can cause the formation of different forms of cholecystolithiasis, and promote the occurrence and development of "solid stones".

RÉSUMÉ

Sustained smouldering, or low-grade activation, of myeloid cells is a common hallmark of several chronic neurological diseases, including multiple sclerosis1. Distinct metabolic and mitochondrial features guide the activation and the diverse functional states of myeloid cells2. However, how these metabolic features act to perpetuate inflammation of the central nervous system is unclear. Here, using a multiomics approach, we identify a molecular signature that sustains the activation of microglia through mitochondrial complex I activity driving reverse electron transport and the production of reactive oxygen species. Mechanistically, blocking complex I in pro-inflammatory microglia protects the central nervous system against neurotoxic damage and improves functional outcomes in an animal disease model in vivo. Complex I activity in microglia is a potential therapeutic target to foster neuroprotection in chronic inflammatory disorders of the central nervous system3.

RÉSUMÉ

OBJECTIVE: This study aims to determine whether persistent T1-weighted lesions signify a complete pathological response (pCR) in breast cancer patients treated with neoadjuvant chemotherapy and surgery, and to evaluate their correlation with imaging responses on MRI. MATERIALS AND METHODS: A retrospective review was conducted on data from breast cancer patients treated between January 2011 and December 2018. Patients who underwent breast MRI and pre- and post-neoadjuvant chemotherapy followed by surgery were included. Those with distant metastasis, no planned surgery, pre-surgery radiation, ineligibility for neoadjuvant chemotherapy, or unavailable surgical pathology were excluded. Groups with and without persistent T1-weighted lesions were compared using the chi-square test for categorical variables and the Student t test or Wilcox rank sum test for continuous variables. Univariate logistic regression was used to evaluate the association of the final pathological response with the presence of T1-persistent lesion and other characteristics. RESULTS: Out of 319 patients, 294 met the inclusion criteria (breast cancer patients treated with neoadjuvant chemotherapy and subsequent surgery); 157 had persistent T1 lesions on post-chemotherapy MRI and 137 did not. A persistent T1 lesion indicated reduced likelihood of complete pathological response (14% vs. 39%, p < 0.001) and imaging response (69% vs. 93%, p < 0.001). Multivariable analysis confirmed these findings: OR 0.37 (95% CI 0.18-0.76), p = 0.007. No other characteristics correlated with T1 residual lesions. CONCLUSION: Persistent T1-weighted lesions without associated abnormal enhancement on post-treatment breast MRI correlate with lower complete pathological and imaging response rates. CLINICAL RELEVANCE STATEMENT: The study underscores the importance of persistent T1-weighted lesions on breast MRI as vital clinical markers, being inversely related to a complete pathological response following neoadjuvant chemotherapy; they should be a key factor in guiding post-neoadjuvant chemotherapy treatment decisions. KEY POINTS: • Persistent T1 lesions on post-chemotherapy breast MRI indicate a reduced likelihood of achieving a complete pathological response (14% vs. 39%, p < 0.001) and imaging response (69% vs. 93%, p < 0.001). • Through multivariable analysis, it was confirmed that the presence of a persistent T1 lesion on breast MRI post-chemotherapy is linked to a decreased likelihood of complete pathological response, with an odds ratio (OR) of 0.37 (95% CI 0.18-0.76; p = 0.007). • In addition to the convention of equating the absence of residual enhancement to complete imaging response, our results suggest that the presence or absence of residual T1 lesions should also be considered.

RÉSUMÉ

AIMS: To evaluate the component patterns and risk stratification in patients with mixed malignant ovarian germ cell tumors (mMOGCT). METHODS: A retrospective study of 70 mMOGCT patients treated in our hospital between 2000 and 2022 was conducted. The recurrence-free survival (RFS), disease-specific survival (DSS), and risk stratification systems based on scoring the identified prognostic factors were assessed. RESULTS: Yolk sac tumor component was the most common type (80%), followed by dysgerminoma (50%), immature teratoma (40%), embryonic carcinoma (27.1%), and chorionic carcinoma (15.7%). The 5-year RFS and DSS rates were 77.9% and 87.9%, respectively. International federation of gynecology and obstetrics (FIGO) stage III-IV (RR 3.253, P = 0.029) and normalization of tumor marker (TM) ≤ 3 cycles of chemotherapy (RR 6.249, P = 0.017) were risk factors for RFS and DSS, respectively. Significant DSS (RR 8.268, P = 0.006) was also noted between patients who had normalized TM ≤ 4 and ≥5 cycles of chemotherapy. FIGO stages I-II and stages III-IV were scored as 0 and 2, respectively. AFP normalization ≤3, 4, and ≥5 cycles of chemotherapy were scored as 0, 1, and 4, respectively. A total score of 0, 1-2, and ≥3 stratified patients into low-risk (43 patients), intermediate-risk (13 patients), and high-risk groups (14 patients), respectively. Patients in three risk stratifications manifested significant differences in DSS (P = 0.010) but not in RFS (P > 0.05). CONCLUSION: Distinct different component patterns existed among mMOGCT patients, and predicting survival outcomes in a universal model was challenging.

RÉSUMÉ

OBJECTIVE: To investigate the role of caspase-1-medicated canonical pyroptosis pathway in chlorogenic acid (CGA) treatment of acute kidney injury (AKI) in mice. METHOD: Twenty-four C57Bl/6J mice were randomized into sham-operated group, cecal ligation and puncture (CLP) group, CLP+dexamethasone group (CLP+DXM group), and CLP+CGA group (n=6) and subjected to either sham operation (laparotomy only) or CLP. After modeling the mice received intravenous infusion of 10 mg/kg normal saline (in sham and CLP groups), 1 µg/kg dexamethasone or 15 mg/kg of chlorogenic acid for 6 h delivered using an intravenous pump. Eight hours after the infusion, renal morphology and histology, renal cell apoptosis, and the renal function parameters such as urea nitrogen (BUN), creatinine (Scr), and kidney injury molecule 1 (KIM-1) were compared among the 4 groups; the 7-day survival rates of the mice were recorded, and the expressions of NLRP3 inflammasomes and key proteins of the caspase-1 pathway in the renal tissue were detected. RESULTS: CGA treatment significantly improved the 7-day survival rate, reduced renal pathologies of the septic mice (P < 0.05), and lowered the levels of BUN, Scr, KIM-1, NLRP3 inflammasome and expressions of key proteins of the caspase-1 pathway. CONCLUSION: CGA alleviates AKI in mice with CLP-induced sepsis by inhibiting NLRP3 inflammasomes and the caspase-1 signaling pathway.

RÉSUMÉ

Objective: To evaluate the surgery combined chemotherapy and radiation in locally advanced neuroendocrine carcinoma of the cervix (NECC) . Methods: This is a single-center retrospective cohort study. Locally advanced NECC patients admitted to Peking Union Medical College Hospital, Chinese Acadmy of Medical Sciences from January 2011 to April 2022 were enrolled. They were divided into concurrent chemoradiotherapy group, and surgery combined with chemotherapy and radiation group. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate. Results: (1) Forty-six cases were included, 22 in concurrent chemoradiotherapy group, 24 in surgery combined chemotherapy and radiation group. With 16 patients (35%, 16/46) received neoadjuvant chemotherapy (NACT), the NACT effective rate was 15/16. (2) The median follow-up time was 27.5 months (range: 10-106 months), with 26 (57%, 26/46) experienced recurrences. There were 4 (9%, 4/46) pelvic recurrences and 25 (54%, 25/46) distant recurrences, and 3 (7%, 3/46) both pelvic and distant recurrences. Compared with concurrent chemoradiotherapy group, surgery combined chemotherapy and radiation group had lower pelvic recurrence rate [14% (3/22) vs 4% (1/24); χ2=1.296, P=0.255] but without statistic difference. Both groups had similar distant recurrence rate [55% (12/22) vs 54% (13/24); χ2=0.001, P=0.979] and overall recurrence rate [59% (13/22) vs 54% (13/24); χ2=0.113, P=0.736]. (3) During the follow-up period, 22 cases (48%, 22/46) died, with 11 cases (50%, 11/22) in concurrent chemoradiotherapy group and 11 cases (46%, 11/24) in surgery combined chemotherapy and radiation group, without significant difference (χ2=0.080, P=0.777). The postoperative 3-year and 5-year OS rates were 62.3% and 36.9%. Compared with concurrent chemoradiotherapy group, the patients in surgery combined chemotherapy and radiation group showed an extended trend in PFS (17.0 vs 32.0 months) and OS (37.0 vs 50.0 months) but without statistic differences (P=0.287, P=0.125). Both groups had similar 3-year OS rate (54.2% vs 69.9%; P=0.138) and 5-year OS rate (36.1% vs 38.8%; P=0.217). Conclusions: Our study supports the multi-modality treatment strategy (including surgery, chemotherapy and radiation) as an important component in the treatment of locally advanced NECC. The combination of surgery, chemotherapy and radiation seems to have advantages in the treatment of locally advanced NECC, but needs to be confirmed by further multicenter studies.

RÉSUMÉ

Obesity is a complex multicausal disease that can cause morbidity and mortality, and there is need for improved knowledge on the underlying mechanisms. Using a mouse model of increased T cell responsiveness, we show that development of obesity can be driven by immune cells. This was confirmed with bone marrow transplantation and adoptive T cell transfer to several recipient mouse models. Single-cell RNA sequencing and CyTOF analysis showed that the mice display altered composition of circulating T cells and increased T cell activation in visceral adipose tissue, suggesting activated T cells as critical players in the increased fat mass. In this study, we provide evidence that obesity can be driven by immune cell activity and in particular by T cells, which could have broad implications for prevention and treatment of this condition.

RÉSUMÉ

Objectives: To analyze the status and temporal changes of disability-adjusted life year (DALY) for stomach and colorectal cancers among registered permanent residents in Changning District of Shanghai Municipality, and provide scientific basis for the prevention and treatment of stomach and colorectal cancers in this district. Methods: Using the cancer registration data of stomach and colorectal cancers from 2002 to 2019, we estimated the indices such as the DALYs, the DALY crude rates, the age-standardized DALY rates, etc. Then we used the Joinpoint regression model to calculate the average annual percent change (AAPC) and annual percent change (APC) to explore the temporal variations in different periods. Results: The DALYs of stomach and colorectal cancers in Changning District from 2002 to 2019 were 55 931 person years and 65 252 person years, respectively. The crude rates of DALY were 512.16/105 and 597.51/105, respectively. We observed a higher disease burden in men than in women, and the peak rate of DALY in stomach cancer was in the 75-79 years age group, while in colorectal cancer the rate was in the 85-years-or-older age group. Joinpoint regression analysis showed that from 2002 to 2019, the age-standardized DALY rate of stomach cancer showed a downward trend (AAPC=-3.86%, P<0.05), while the trend of colorectal cancer was not statistically significant(AAPC=-0.08%, P>0.05). However, the trends in the age-standardized DALY rates of colorectal cancer were different between males and females, with males showing an upward trend (AAPC=1.24%, P<0.05) and females showing a downward trend (AAPC=-1.67%, P<0.05). Conclusions: The DALY of stomach and colorectal cancers in Changning District of Shanghai showed a decreasing trend. Males and the middle-aged and elderly populations are still the key targets for disease prevention and control in this district.

RÉSUMÉ

AIM: To assess the feasibility of a radiomics model based on unenhanced magnetic resonance imaging (MRI) to differentiate small hepatocellular carcinoma (S-HCC) (≤2 cm) and pre-hepatocellular carcinoma (Pre-HCC). MATERIALS AND METHODS: One hundred and fourteen histopathologically confirmed 114 hepatic nodules were analysed retrospectively. All patients had undergone MRI before surgery using a 3 T MRI system. Each nodule was segmented on unenhanced MRI sequences (T1-weighted imaging [T1] and T2WI with fat-suppression [FS-T2]). Radiomics features were extracted and the optimal features were selected using the least absolute shrinkage and selection operator (LASSO). The support vector machine (SVM) was used to establish the radiomics model. One abdominal radiologist performed the conventional qualitative analysis for classification of S-HCC and Pre-HCC. The diagnostic performances of the radiomics and radiologist models were evaluated using receiver operating characteristic (ROC) analysis. RESULT: Radiomics features (n=1,223) were extracted from each sequence and the optimal features were selected from T1, FS-T2, and T1+FS-T2 to construct the radiomics models. The radiomics model based on T1+FS-T2 showed the best performance among the three models, with areas under the ROC curves (AUCs) of 0.95 (95 % confidence interval [CI], 0.875-0.986) and 0.942 (95 % CI, 0.775-0.985), accuracies of 86 % and 88.5 %, sensitivities of 94.12 % and 100 %, and specificities of 85.48 % and 85.19 %, respectively. The radiomics model on FS-T2 showed better performance on a single sequence than that of the T1-based model. The diagnostic performance for the radiomic model was significantly higher than that for the radiologist (AUC = 0.518, p<0.05). CONCLUSION: This study suggested that a radiomics model based on unenhanced MRI may serve as a feasible and non-invasive tool to classify S-HCC and Pre-HCC.

RÉSUMÉ

BACKGROUND: There is a paucity of literature examining the differences between patient-reported outcome measures after planned and unplanned cesarean delivery using a validated quality of recovery tool. The Obstetric Quality of Recovery-10 (ObsQoR-10) scoring tool has been validated to quantify functional recovery after cesarean delivery. We aimed to use the ObsQoR-10 to compare the postoperative recovery characteristics of patients undergoing planned and unplanned cesarean deliveries. METHODS: We conducted a prospective single-center observational study. Patients undergoing planned and unplanned cesarean deliveries under neuraxial anesthesia were asked to complete the ObsQoR-10 questionnaire 24 hours, 48 hours, and 1 week postpartum. We collected information on total in-hospital postoperative opioid consumption and patients´ perception of readiness for discharge at 24 and 48 hours postpartum. Additionally, patient characteristics were collected to assess their correlation with our findings. RESULTS: We included 112 patients (56 in each group). No statistical differences in ObsQoR-10 scores at 24 hours, 48 hours, and 1 week postpartum were observed between the planned and unplanned cesarean deliveries. Additionally, there was no difference between the groups in patients' perception of readiness for hospital discharge at 24 and 48 hours and opioid consumption in the first 2 days after surgery. Most patients in both groups did not think they would be ready for discharge at 24 hours postpartum. Analysis of the individual components of ObsQoR-10 at 24 hours showed a difference in the responses assessing the severity of shivering (higher in unplanned cesarean deliveries) and the ability to look after personal hygiene (lower in unplanned cesarean deliveries). CONCLUSIONS: As assessed by the ObsQoR-10, no significant difference in the quality of recovery was observed between patients undergoing planned and unplanned cesarean delivery.

RÉSUMÉ

Sustained smouldering, or low grade, activation of myeloid cells is a common hallmark of several chronic neurological diseases, including multiple sclerosis (MS) 1 . Distinct metabolic and mitochondrial features guide the activation and the diverse functional states of myeloid cells 2 . However, how these metabolic features act to perpetuate neuroinflammation is currently unknown. Using a multiomics approach, we identified a new molecular signature that perpetuates the activation of myeloid cells through mitochondrial complex II (CII) and I (CI) activity driving reverse electron transport (RET) and the production of reactive oxygen species (ROS). Blocking RET in pro-inflammatory myeloid cells protected the central nervous system (CNS) against neurotoxic damage and improved functional outcomes in animal disease models in vivo . Our data show that RET in myeloid cells is a potential new therapeutic target to foster neuroprotection in smouldering inflammatory CNS disorders 3 .

RÉSUMÉ

PURPOSE: A zone of differential block to cold has been recently documented during labour epidural analgesia, with an upper sensory block level (USBL) and a lower sensory block level (LSBL). We aimed to determine the correlation between USBL and LSBL to cold and pinprick and sensory block level to light touch during labour epidural analgesia. METHODS: We conducted a prospective observational study in patients requesting labour epidural analgesia. We placed an epidural catheter at L2/L3 or L3/L4, followed by a programmed intermittent epidural bolus plus patient-controlled epidural analgesia regimen. We assessed the sensory block levels 140 min after administering the loading dose. The primary outcomes were the USBL and LSBL to cold and pinprick and the sensory block level to light touch. RESULTS: We studied 30 patients. The median [interquartile range (IQR)] USBL and LSBL to ice were T7 [T7-T6] and T9 [T10-T8], respectively. The median [IQR] USBL and LSBL to pinprick were T8 [T10-T6] and T10 [T12-T10], respectively. There was a strong correlation between USBL to ice and pinprick (Spearman correlation coefficient, 0.57) and between LSBL to ice and pinprick (Spearman correlation coefficient, 0.52). There was no significant correlation between sensory block level to light touch and either USBL or LSBL to ice or pinprick. CONCLUSION: We observed two sensory block levels to ice and pinprick. Further studies are required to understand if one modality-cold or pinprick-is superior to the other in assessing sensory block levels in this context. Light touch is unreliable as a modality of sensory block assessment during labour epidural analgesia. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05187962); registered 12 January 2022.


RéSUMé: OBJECTIF: Une zone de bloc différentiel de réaction au froid a récemment été documentée pendant l'analgésie péridurale obstétricale, avec un niveau de bloc sensoriel supérieur (USBL, pour upper sensory block level) et un niveau de bloc sensoriel inférieur (LSBL, pour lower sensory block level). Notre objectif était de déterminer la corrélation entre l'USBL et le LSBL au contact du froid et de la piqûre et le niveau de bloc sensoriel au toucher léger pendant l'analgésie péridurale obstétricale. MéTHODE: Nous avons mené une étude observationnelle prospective chez des patient·es demandant une analgésie péridurale obstétricale. Nous avons placé un cathéter péridural au niveau L2/L3 ou L3/L4, suivi d'une administration programmée de bolus périduraux plus un régime d'analgésie péridurale contrôlée par le/la patient·e. Nous avons évalué les niveaux de bloc sensoriel 140 min après l'administration de la dose de charge. Les critères d'évaluation principaux étaient l'USBL et le LSBL en réaction au froid et à la piqûre d'épingle et le niveau de bloc sensoriel en réaction au toucher léger. RéSULTATS: Nous avons étudié 30 patient·es. Les USBL et LSBL médians [écart interquartile (ÉIQ)] à la glace étaient situés au niveau T7 [T7-T6] et T9 [T10-T8], respectivement. Les USBL et LSBL médians [écart interquartile (ÉIQ)] à la piqûre étaient localisés au niveau T8 [T10­T6] et T10 [T12­T10], respectivement. Il y avait une forte corrélation entre l'USBL à la glace et à la piqûre (coefficient de corrélation de Spearman, 0,57) et entre le LSBL à la glace et à la piqûre (coefficient de corrélation de Spearman, 0,52). Il n'y avait pas de corrélation significative entre le niveau de bloc sensoriel en réaction au toucher léger et l'USBL ou le LSBL en réaction à la glace ou à la piqûre. CONCLUSION: Nous avons observé deux niveaux de bloc sensoriel à la glace et à la piqûre. D'autres études sont nécessaires pour comprendre si une modalité ­ le froid ou la piqûre ­ est supérieure à l'autre pour évaluer les niveaux de bloc sensoriel dans ce contexte. Le toucher léger n'est pas fiable en tant que modalité d'évaluation du bloc sensoriel pendant l'analgésie péridurale obstétricale.

RÉSUMÉ

BACKGROUND: Serum lipid levels are associated with cancer risk. However, there still have uncertainties about the single and combined effects of low lipid levels on cancer risk. METHODS: A prospective cohort study of 33,773 adults in Shanghai between 2016 and 2017 was conducted. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels were measured. Cox proportional hazard models were used to assess the association of single and combined lipids with overall, lung, colon, rectal, thyroid gland, stomach, and female breast cancers. The effect of the combination of abnormal lipid score and lifestyle on cancer was also estimated. RESULTS: A total of 926 incident cancer cases were identified. In the RCS analysis, hazard ratios (HRs) of overall cancer for individuals with TC < 5.18 mmol/L or with LDL-C < 3.40 mmol/L were higher. Low TC was associated with higher colorectal cancer risk (HR [95% CI] = 1.76 [1.09-2.84]) and low HDL-C increased thyroid cancer risk by 90%. Abnormal lipid score was linearly and positively associated with cancer risk, and smokers with high abnormal lipid scores had a higher cancer risk, compared to non-smokers with low abnormal lipid scores (P < 0.05). CONCLUSIONS: Low TC levels were associated with an increased risk of overall and colorectal cancer. More attention should be paid to participants with high abnormal lipid scores and unhealthy lifestyles who may have a higher risk of developing cancer. Determining the specific and comprehensive lipid combinations that affect tumorigenesis remains a valuable challenge.

RÉSUMÉ

Social devaluation of being overweight is common in daily life, but little is known about the weight stigma in romantic relationships. The present study investigated the roles of maladaptive and adaptive coping strategies in the relation between the experience of weight stigma in romantic relationships and depressive symptoms in men and women, respectively. Analyses of gender differences and structural equation modeling yielded several findings. First, while men and women experienced similar levels of weight stigma from their romantic partners, women were more likely to use exercise avoidance, disengagement coping, and reappraisal coping strategies, and to exhibit more depressive symptoms than men. Second, men who experienced weight stigma tended to cope with it through exercise avoidance and disengagement coping, which were related to greater depressive symptoms. Men also coped with weight stigma adaptively via reappraisal coping, which was additionally associated with more positive affect. Third, the relation between the experience of weight stigma and depressive symptoms in women was only explained by using disengagement coping. These findings extend the understanding of weight stigma to a specific context and provide some insight that future interventions to reduce the impacts of weight stigma should be tailored accordingly for men and women.

RÉSUMÉ

INTRODUCTION: Sepsis and intraventricular hemorrhage (IVH) are associated with poorer long-term neurodevelopmental outcomes in very preterm infants (VPIs), but less is known about the long-term effect of meningitis and the combined impact of both meningitis and IVH. Our objective was to examine the long-term neurodevelopmental outcomes of VPIs with late onset sepsis and meningitis, with and without IVH, in Canada. METHODS: We conducted a retrospective cohort study of all infants <29 weeks GA who were admitted to 26 tertiary-level neonatal intensive care units in the Canadian Neonatal Network (CNN) and Canadian Neonatal Follow-Up Network (CNFUN) databases, from January 1, 2010, to December 31, 2016. RESULTS: Of the 6,322 infants in the cohort, 4,575 had no infection, 1,590 had late onset culture-positive bloodstream infection (CPBSI) only, and 157 had late onset meningitis. There was a significant (p < 0.05) trend of increasing rates of significant neurodevelopmental delay (sNDI) when comparing infants with no infection (sNDI rate 15.0%), late onset CPBSI (sNDI rate 22.9%), and late onset meningitis (sNDI rate 32.0%), even after adjustment for infant characteristics. Similar trends were observed for neurodevelopmental impairment, cerebral palsy, and individual Bayley-III scores <85 for cognitive, language, and motor development. There was an additive effect of IVH in all infant categories, but there was no multiplicative effect between IVH and late onset meningitis. CONCLUSION: There was an increasing trend of adverse neurodevelopmental outcomes when infants with no infection, late onset CPBSI and late onset meningitis are compared. IVH had an additive effect.

RÉSUMÉ

BACKGROUND: Multidisciplinary cancer conferences consist of regular meetings between diverse specialists working together to share clinical decision making in cancer care. The aim of this study was to systematically review and meta-analyze the effect of multidisciplinary cancer conference intervention on the overall survival of patients with cancer. METHODS: A systematic literature search was conducted on Ovid MEDLINE, EMBASE, and the Cochrane Controlled Register of Trials for studies published up to July 2023. Studies reporting on the impact of multidisciplinary cancer conferences on patient overall survival were included. A standard random-effects model with the inverse variance-weighted approach was used to estimate the pooled hazard ratio of mortality (multidisciplinary cancer conference vs non-multidisciplinary cancer conference) across studies, and the heterogeneity was assessed by I2. Publication bias was examined using funnel plots and the Egger test. RESULTS: A total of 134 287 patients with cancer from 59 studies were included in our analysis, with 48 467 managed by multidisciplinary cancer conferences and 85 820 in the control arm. Across all cancer types, patients managed by multidisciplinary cancer conferences had an increased overall survival compared with control patients (hazard ratio = 0.67, 95% confidence interval = 0.62 to 0.71, I2 = 84%). Median survival time was 30.2 months in the multidisciplinary cancer conference group and 19.0 months in the control group. In subgroup analysis, a positive effect of the multidisciplinary cancer conference intervention on overall survival was found in breast, colorectal, esophageal, hematologic, hepatocellular, lung, pancreatic, and head and neck cancer. CONCLUSIONS: Overall, our meta-analysis found a significant positive effect of multidisciplinary cancer conferences compared with controls. Further studies are needed to establish nuanced guidelines when optimizing multidisciplinary cancer conference integration for treating diverse patient populations.
