Long-Term Results of 2-Stage Turnbull-Cutait Pull-Through Coloanal Anastomosis for Low Rectal Cancer: A Randomized Clinical Trial.

In patients operated on for low rectal cancer, 2-stage Turnbull-Cutait pull-through hand-sewn coloanal anastomosis provides benefits in terms of postoperative morbidity compared with standard hand-sewn coloanal anastomosis associated with diverting ileostomy and further ileostomy reversal. To compare long-term results of these 2 techniques after ultralow rectal resection for rectal cancer. In this randomized multicenter clinical trial, neither patients nor surgeons were blinded for technique. Patients were recruited in 3 centers. Patients undergoing ultralow anterior rectal resection needing hand-sewn coloanal anastomosis were randomly assigned to 2-stage Turnbull-Cutait pull-through hand-sewn coloanal anastomosis (n = 46) or standard hand-sewn coloanal anastomosis associated with diverting ileostomy (n = 46). All patients underwent ultralow anterior resection. Patients assigned to the 2-stage Turnbull-Cutait pull-through group underwent exteriorization of a segment of left colon through the anal canal. After 6 to 10 days, the exteriorized colon was resected and a delayed hand-sewn coloanal anastomosis performed. For patients assigned to standard coloanal anastomosis, the hand-sewn coloanal anastomosis was performed with diverting ileostomy during the first operation. Ileostomy closure was scheduled after adjuvant treatment was completed in about 6 to 8 months. The study aimed to compare the differences between the 2 groups in terms of long-term surgery-related morbidity, functional, and oncological outcomes at 3 years postoperatively. Data were analyzed from October 1, 2018, through October 31, 2021. The 92 patients randomized in the first study were included for the 3-year follow-up. The overall morbidity rate in the 2 groups showed that 15 patients (16.3%) had complications with a difference of 6.52 (95% CI, -8.93 to 21.79). Nine patients (19.6%) and 6 patients (13.0%) in the 2-stage Turnbull-Cutait pull-through group and hand-sewn coloanal anastomosis group, respectively, had complications without statistically significant differences (P = .57). Oncological results were comparable between the groups. Long-term fecal continence in the CCA and TCA groups, respectively, assessed using the Wexner Incontinence Score was 10.9 (5.50-15.5) vs 13.0 (7.25-16.0; P = .92), Low Anterior Resection Syndrome score was 32.0 (21.0-37.0) vs 34.0 (23.2-38.5; P = .76), and Colorectal Functional Outcome score was 38.5 (23.0-47.1) vs 40.8 (23.3-58.2; P = .30). In this study, after a 3-year follow-up period, 2-stage Turnbull-Cutait anastomosis for ultralow rectal cancer could be considered as a surgical alternative that has the valuable benefit of avoiding a temporary stoma with similar results in terms of morbidity, fecal continence, patient satisfaction, quality of life, and oncological outcomes when compared with hand-sewn coloanal anastomosis with ileostomy.

Mitral valve replacement in young patients: review and current challenges.

Mitral valve repair is the ideal intervention for mitral valve disease with excellent long-term survival comparable to the age-matched general population. When the mitral valve is not repairable, mechanical prostheses may be associated with improved survival as compared with biological prostheses. Newer mechanical and biological valve prostheses have the potential to improve outcomes following mitral valve replacement in young patients. Patients presenting for mitral valve surgery after failed transcatheter mitral valve-in-valve have high rates of postoperative mortality and morbidity, exceeding those seen with reoperative mitral valve surgery, which poses issues in young patients who have a higher cumulative incidence of reintervention.

Genital Burns Are Associated with Worse Psychosocial and Physical Outcomes.

Genital burns are unique and complex injuries that impact patients physically and emotionally. This study investigates the specific impact of genital burns on psychosocial and physical outcomes. A retrospective cohort study was conducted using the TriNetX database, encompassing over 117 million patients from U.S. healthcare institutions. Patients with genital burns were identified and categorized into sub-cohorts based on TBSA and burn degree. Propensity score matching and cohort balancing were performed based on age, gender, race, and ethnicity. Outcomes were analyzed both short-term (1 month) and long-term (5 years), focusing on psychiatric and physical aspects. This study identified 3,496 genital burn patients over a 15-year period. Analyses revealed that genital burns significantly increased short-term risk of death (RR: 2.8), anxiety (RR: 2.656), hospitalization (RR: 2.167), and any anxiety, PTSD, or depression (RR: 2.363), and long-term risk of death (RR: 1.658) and pruritus (RR: 1.58) (all p<0.05). Interestingly, genital burn patients showed a lower risk of chronic joint pain compared to other burn injuries (RR: 0.815) (p<0.05). These results occurred independently of the extent of TBSA. Genital burns have a distinctive impact on patients, leading to higher rates of certain psychiatric morbidities and physical complications. This study highlights the need for tailored care and consideration of the unique challenges faced by patients with genital burns, both in the immediate aftermath and in the long term. Understanding the specific impacts of genital burns is vital for healthcare practitioners to develop care strategies and better support for patients recovering from such injuries.

Surgical outcomes of major vascular resection for retroperitoneal liposarcoma from a high‑volume sarcoma center: a propensity score matching analysis

PurposeRadical resection of retroperitoneal liposarcoma (RLPS) may necessitate vascular resection and reconstruction. The study was conducted to assess surgical outcomes of surgery for RLPS with major vascular involvement.MethodsPatients with RLPS who underwent surgical resection at the Sarcoma Center of Peking University Cancer Hospital between April 2011 and December 2022 were identified from a prospectively maintained database. Patients were classified into two groups: vascular resection and non-vascular resection groups. A propensity score matching analysis was performed to eliminate baseline differences between the groups. Surgical details and postoperative outcomes were analyzed. Furthermore, prognostic factors for local recurrence-free survival (LRFS) and overall survival (OS) were assessed.ResultsOverall, 199 patients were identified and the median follow-up period was 48 (interquartile range [IQR] 45–69) months. Vascular resection was performed in 42 (21%) patients, 25 of whom had vascular infiltration. A total of 39 patients had vascular replacement and 3 patients underwent partial resection (side-wall resection). Vascular resection was burdened by higher rates of major morbidity (38% vs. 14%, p < 0.001) and 30-day mortality (7.1% vs. 1.3%, p = 0.005). After propensity-matched analysis, patients who underwent vascular resection had 5-year LRFS and OS rates comparable to those without vascular involvement. Major vascular resection was not an independent risk factor for LRFS or OS.ConclusionsAlthough accompanied by increased risks of major morbidity and mortality, the major vascular resection enabled radical resection in patients with advanced RLPS, affording comparable 5-year LRFS and OS rates compared to those who did not.

Lung Adenocarcinoma Systems Biomarker and Drug Candidates Identified by Machine Learning, Gene Expression Data, and Integrative Bioinformatics Pipeline.

Lung adenocarcinoma (LUAD) is a significant planetary health challenge with its high morbidity and mortality rate, not to mention the marked interindividual variability in treatment outcomes and side effects. There is an urgent need for robust systems biomarkers that can help with early cancer diagnosis, prediction of treatment outcomes, and design of precision/personalized medicines for LUAD. The present study aimed at systems biomarkers of LUAD and deployed integrative bioinformatics and machine learning tools to harness gene expression data. Predictive models were developed to stratify patients based on prognostic outcomes. Importantly, we report here several potential key genes, for example, PMEL and BRIP1, and pathways implicated in the progression and prognosis of LUAD that could potentially be targeted for precision/personalized medicine in the future. Our drug repurposing analysis and molecular docking simulations suggested eight drug candidates for LUAD such as heat shock protein 90 inhibitors, cardiac glycosides, an antipsychotic agent (trifluoperazine), and a calcium ionophore (ionomycin). In summary, this study identifies several promising leads on systems biomarkers and drug candidates for LUAD. The findings also attest to the importance of integrative bioinformatics, structural biology and machine learning techniques in biomarker discovery, and precision oncology research and development.

NUSAP1 Promotes Immunity and Apoptosis by the SHCBP1/JAK2/STAT3 Phosphorylation Pathway to Induce Dendritic Cell Generation in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and is associated with high morbidity and mortality rates. The aims of this study were to investigate the immune-promoting action of nucleolar and spindle-associated protein 1 (NUSAP1) and identify an immunotherapy target for HCC. The Cancer Genome Atlas (TCGA) was used to analyze interaction molecules and immune correlation. The interaction between NUSAP1 and SHC binding and spindle associated 1 (SHCBP1) was examined. The role of the SHCBP1/Janus kinase 2/signal transducer and activator of transcription 3 (SHCBP1/JAK2/STAT3) pathway in this process was explored. After co-culture with HCC cell lines, the differentiation of peripheral blood mononuclear cells (PBMCs) into dendritic cells (DC) was evaluated by measuring the expression of surface factors CD1a and CD86. Pathological tissues from 50 patients with HCC were collected to validate the results of cell experiments. The expression levels of CD1a and CD86 in tissues were also determined. The results show that NUSAP1 interacted with SHCBP1 and was positively correlated with DC. In HCC cell lines, an interaction was observed between NUSAP1 and SHCBP1. It was verified that NUSAP1 inhibited the JAK2/STAT3 phosphorylation pathway by blocking SHCBP1. After co-culture, the levels of CD1a and CD86 in PBMC were elevated. In the clinical specimens, CD1a and CD86 expression levels were significantly higher in the high-NUSAP1 group versus the low-NUSAP1 group. In Summary, NUSAP1 enhanced immunity by inhibiting the SHCBP1/JAK2/STAT3 phosphorylation pathway and promoted DC generation and HCC apoptosis. NUSAP1 may be a target of immunotherapy for HCC.

Nicotinamide riboside restores nicotinamide adenine dinucleotide levels and alleviates brain injury by inhibiting oxidative stress and neuroinflammation in a mouse model of intracerebral hemorrhage.

Hemorrhagic stroke is a global health problem owing to its high morbidity and mortality rates. Nicotinamide riboside is an important precursor of nicotinamide adenine dinucleotide characterized by a high bioavailability, safety profile, and robust effects on many cellular signaling processes. This study aimed to investigate the protective effects of nicotinamide riboside against collagenase-induced hemorrhagic stroke and its underlying mechanisms of action. An intracerebral hemorrhage model was constructed by stereotactically injecting collagenase into the right striatum of adult male Institute for Cancer Research mice. After 30 minutes, nicotinamide riboside was administered via the tail vein. The mice were sacrificed at different time points for assessments. Nicotinamide riboside reduced collagenase-induced hemorrhagic area, significantly reduced cerebral water content and histopathological damage, promoted neurological function recovery, and suppressed reactive oxygen species production and neuroinflammation. Nicotinamide riboside exerts neuroprotective effects against collagenase-induced intracerebral hemorrhage by inhibiting neuroinflammation and oxidative stress.

Systematic Mendelian Randomization Exploring Druggable Genes for Hemorrhagic Strokes.

Patients with hemorrhagic stroke have high rates of morbidity and mortality, and drugs for prevention are very limited. Mendelian randomization (MR) analysis can increase the success rate of drug development by providing genetic evidence. Previous MR analyses only analyzed the role of individual drug target genes in hemorrhagic stroke; therefore, we used MR analysis to systematically explore the druggable genes for hemorrhagic stroke. We sequentially performed summary-data-based MR analysis and two-sample MR analysis to assess the associations of all genes within the database with intracranial aneurysm, intracerebral hemorrhage, and their subtypes. Validated genes were further analyzed by colocalization. Only genes that were positive in all three analyses and were druggable were considered desirable genes. We also explored the mediators of genes affecting hemorrhagic stroke incidence. Finally, the associations of druggable genes with other cardiovascular diseases were analyzed to assess potential side effects. We identified 56 genes that significantly affected hemorrhagic stroke incidence. Moreover, TNFSF12, SLC22A4, SPARC, KL, RELT, and ADORA3 were found to be druggable. The inhibition of TNFSF12, SLC22A4, and SPARC can reduce the risk of intracranial aneurysm, subarachnoid hemorrhage, and intracerebral hemorrhage. Gene-induced hypertension may be a potential mechanism by which these genes cause hemorrhagic stroke. We also found that blocking these genes may cause side effects, such as ischemic stroke and its subtypes. Our study revealed that six druggable genes were associated with hemorrhagic stroke, and the inhibition of TNFSF12, SLC22A4, and SPARC had preventive effects against hemorrhagic strokes.

Integrated Assessment of GFAP and UCH-L1 for their utility in severity assessment and outcome prediction in Traumatic Brain Injury.

This study aimed to explore the potential of glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase-L1 (UCH-L1) as biomarkers for diagnosis and prognosis in mild and severe TBI cases, including TBI-related deaths. This prospective cohort study includes 40 cases each of mild, severe, fatal TBI cases, and 40 healthy controls. Serum samples were collected from live patients at 8 and 20h post injury for UCH-L1 and GFAP respectively, and from deceased patients within 6h of death. Elevated levels of both GFAP and UCH-L1 were observed in patients with severe and fatal TBI cases. These biomarkers exhibited promising potential for predicting various Glasgow Outcome Scale Extended (GOSE) categories. Combining GFAP and UCH-L1 yielded higher predictive accuracy both for diagnosis and prognosis in TBI cases. The study additionally established specific cut-off levels for GFAP and UCH-L1 stratified according to the severity and prognosis. GFAP and UCH-L1 individually demonstrated moderate to good discrimination capacity in predicting TBI severity and functional outcomes. However, combining these biomarkers is recommended for improved diagnostic and prognostic utility. This precision tool can enhance patient care, enabling tailored treatment plans, ultimately reducing morbidity and mortality rates in TBI cases.

Birth Preparedness and Complication Readiness Among Rural Pregnant Women of Tamilnadu: A Cross Sectional Study

Background: Birth preparedness and complication readiness serve as valuable tactics for enhancing the provision of maternal and child care services, consequently reducing morbidity and mortality associated with childbirth. Anticipating childbirth and possessing prior awareness of potential complications enables women to access services promptly. Methods: In 2022, a community-based cross-sectional study was conducted involving a sample of 480 pregnant women. Data on Birth Preparedness and Complication Readiness (BPCR) were gathered using a pretested and standardized questionnaire. Data analysis was performed utilizing SPSS version 20. The questionnaire encompassed inquiries regarding birth preparedness, such as the selection of a health facility, designation of a birth attendant, arrangement for transportation, securing a blood donor, and whether the woman had saved money for delivery. Complication readiness was assessed through questions concerning complications during pregnancy, delivery, and the neonatal period. Results: Out of the 480 pregnant women included in the study, 30.8% were classified as belonging to the upper middle class. Additionally, 55% of the participants had experienced multiple pregnancies, while 74.2% were identified as being in their third trimester. Furthermore, 70% of the women had undergone their initial Antenatal Care (ANC) checkup before reaching 12 weeks of gestation. Despite these demographics, the study found a general lack of awareness regarding Birth Preparedness and Complication Readiness (BPCR) among the participants. Conclusion: The study indicates a low level of birth preparedness and complication readiness within Rural Tamilnadu. To address this issue effectively, targeted health education strategies should be directed towards young couples and adolescent girls, who represent the future mothers. Implementing both individual and community-level interventions focused on birth preparedness and complication readiness has the potential to enhance maternal service delivery and ultimately reduce both morbidity and mortality rates associated with childbirth.

Machine learning opportunities to predict obstetric haemorrhages

Obstetric hemorrhages (OH) are the main preventable cause of morbidity, mortality and cases of "near miss" among obstetric complications worldwide. Early preventive measures based on the OH prediction allow to profoundly reduce the rate of female mortality and morbidity as well as prevent the economic costs of patient intensive care, blood transfusion, surgical treatment and long-term hospitalization. Postpartum haemorrhage (PPH) is the most frequent obstetric haemorrhage determined by one of the four causes: a uterine tonus disorder, maternal birth trauma, retention of placenta parts and blood-clotting disorder. There is still a need for the continued search for an accurate and reliable prediction method despite multiple attempts to develop an effective system for predicting OH. The solution to this may be reasonably considered an innovative method such as artificial intelligence (AI) including computer technologies capable of obtaining conclusions similar to human thinking. One of the particular AI variants is presented by machine learning (ML), which develops accurate predictive models using computer analysis. Machine learning is based on computer algorithms, the most common among them in medicine are the decision tree (DT), naive Bayes classifier (NBC), random forest (RF), support vector machine (SVM), artificial neural network (ANNs), deep neural network (DNN) or deep learning (DL) and convolutional neural network (CNN). Here, we review the main stages of ML, the principles of algorithms action, and the prospects for using AI to predict OH in real-life clinical practice.

Navigating the Modern Landscape of Sepsis: Advances in Diagnosis and Treatment

Sepsis poses a significant threat to human health due to its high morbidity and mortality rates worldwide. Traditional diagnostic methods for identifying sepsis or its causative organisms are time-consuming and contribute to a high mortality rate. Biomarkers have been developed to overcome these limitations and are currently used for sepsis diagnosis, prognosis prediction, and treatment response assessment. Over the past few decades, more than 250 biomarkers have been identified, a few of which have been used in clinical decision-making. Consistent with the limitations of diagnosing sepsis, there is currently no specific treatment for sepsis. Currently, the general treatment for sepsis is conservative and includes timely antibiotic use and hemodynamic support. When planning sepsis-specific treatment, it is important to select the most suitable patient, considering the heterogeneous nature of sepsis. This comprehensive review summarizes current and evolving biomarkers and therapeutic approaches for sepsis.

Deep learning prediction of survival in patients with heart failure using chest radiographs.

Heart failure (HF) is associated with high rates of morbidity and mortality. The value of deep learning survival prediction models using chest radiographs in patients with heart failure is currently unclear. The aim of our studyisto develop and validate a deep learning survival prediction model using chest X-ray (DLSPCXR) in patients with HF. The study retrospectively enrolled a cohort of 353 patients with HF who underwent chest X-ray (CXR) at our institution between March 2012 and March 2017. The dataset was randomly divided into training (n = 247) and validation (n = 106) datasets. Univariate and multivariate Cox analysis were conducted on the training dataset to develop clinical and imaging survival prediction models. The DLSPCXR was trained and the selected clinical parameters were incorporated into DLSPCXR to establish a new model called DLSPinteg. Discrimination performance was evaluated using the time-dependent area under the receiver operating characteristic curves (TD AUC) at 1, 3, and 5-years survival. Delong's test was employed for the comparison of differences between two AUCs of different models. The risk-discrimination capability of the optimal model was evaluated by the Kaplan-Meier curve. In multivariable Cox analysis, older age, higher N-terminal pro-B-type natriuretic peptide (NT-ProBNP), systolic pulmonary artery pressure (sPAP) > 50mmHg, New York Heart Association (NYHA) functional class III-IV and cardiothoracic ratio (CTR) ≥ 0.62 in CXR were independent predictors of poor prognosis in patients with HF. Based on the receiver operating characteristic (ROC) curve analysis, DLSPCXR had better performance at predicting 5-year survival than the imaging Cox model in the validation cohort (AUC: 0.757 vs. 0.561, P = 0.01). DLSPinteg as the optimal model outperforms the clinical Cox model (AUC: 0.826 vs. 0.633, P = 0.03), imaging Cox model (AUC: 0.826 vs. 0.555, P < 0.001), and DLSPCXR (AUC: 0.826 vs. 0.767, P = 0.06). Deep learning models using chest radiographs can predict survival in patients with heart failure with acceptable accuracy.

The Era of Radial-Specific Catheters: A Multicenter Comparison of the Armadillo and RIST Catheters in Transradial Procedures.

As the radial approach is gaining popularity in neurointervention, new radial-specific catheters are being manufactured while taking into consideration the smaller size of the radial artery, different trajectories of angles into the great vessels from the arm, and subsequent force vectors. We compared outcomes of transradial procedures performed using the Armadillo catheter (Q'Apel Medical Inc.) and the RIST radial guide catheter (Medtronic). This is a retrospective multicenter study comparing outcomes of transradial neuroendovascular procedures using the Armadillo and RIST catheters at 2 institutions between 2021 and 2024. The study comprised 206 patients, 96 of whom underwent procedures using the Armadillo and 110 using the RIST. Age and sex were comparable across cohorts. In most procedures, 1 target vessel was catheterized (Armadillo: 94.8% vs 89.1%, P = .29) with no significant difference between cohorts. The use of an intermediate catheter was minimal in both cohorts (Armadillo 5.2% vs RIST: 2.7%, P = .36), and the median number of major vessel catheterization did not significantly differ between cohorts (Armadillo: 1 [1-4] vs RIST: 1 [0-6], P = .21). Failure to catheterize the target vessel was encountered in 1 case in each cohort (Armadillo: 1.0% vs RIST: 0.9%, P = .18), and the rate did not significantly differ between cohorts. Similarly, the rate of conversion to femoral access was comparable between cohorts (Armadillo: 2.1% vs RIST: 1.8%, P = .55). There was no significant difference in access site complications (Armadillo: 1% vs RIST: 2.8%, P = .55) or neurological complications (Armadillo: 3.1% vs RIST: 5.5%, P = .42) between cohorts. No significant difference in successful catheterization of target vessels, procedure duration, triaxial system use, complication rates, or the need for transfemoral cross-over was observed between both catheters. Both devices offer high and comparable rates of technical success and low morbidity rates.

Long-Term Outcomes Following the Ross Procedure in Neonates and Infants: A Multi-Institutional Analysis

ObjectivesFor neonates and infants with aortic valve pathology, the Ross procedure has historically been associated with high rates of morbidity and mortality. Data regarding long-term durability are lacking. MethodsThe international, multi-institutional Ross Collaborative included six tertiary-care centers. Infants who received a Ross operation between 1996-2016 (allowing a minimum five years of follow-up) were retrospectively identified. Serial echocardiograms were examined to study evolution in neoaortic size and function. ResultsPrimary diagnoses for the 133 patients (n=30 neonates) included isolated aortic stenosis (AS; 14%, n=19), Shone complex (14%, n=19), and AS+other (excluding Shone complex; n=95, 71%) including arch obstruction (n=55), left ventricular hypoplasia (n=9), and mitral disease (>moderate stenosis or regurgitation, n=31). At the time of Ross, median age was 96 (IQR 36-186) days and median weight was 4.4 (3.6-6.5) kg. In-hospital mortality occurred in 13/133 (10%) patients (4/30 [13%] neonates). Post-discharge mortality occurred in 10/120 (8%) patients at a median 298 days post-Ross. Post-Ross neoaortic dilatation occurred, peaking at 4-5 standard deviations above normal at 2-3 years before returning to near-baseline z-score at a median follow-up of 11.5 [6.4-17.4] years. Autograft/LVOT reintervention was required in 5/120 (4%) patients at a median 10.3 [4.1-12.8] years. Freedom from >moderate neoaortic regurgitation (AR) was 86% at 15 years. ConclusionsNeonates and infants experience excellent post-discharge survival and long-term freedom from autograft reintervention and AR following Ross. Neoaortic dilatation normalizes in this population in the long-term. Increased consideration should be given to Ross in neonates and infants with aortic valve disease.

Assessment of knowledge and awareness of stroke among the Syrian population: unveiling the current landscape in Syria through the first nationally representative study

Stroke is a global public health concern, contributing to high rates of morbidity and mortality. In Syria, the current conflict and associated challenges have had a profound impact on healthcare infrastructure, including education and awareness programs related to stroke. An essential aspect of preventing stroke is the awareness of individuals. The study aimed to investigate factors associated with knowledge and awareness of stroke among Syrian people. A cross-sectional national representative study was conducted in Syria. The questionnaire was created on Google form and disseminated as a link through online platform social media like Facebook, WhatsApp, and Twitter. The population of the study was divided using proportionate random sampling into the 14 governorates. A random sample was selected from each area. The STROBE reporting guideline for cross-sectional studies was followed. Logistic regression analysis was performed to identify the factors associated with poor knowledge of stroke. A total of 1013 Syrian adults participated in the study. With more than half of them were females (53.5%) and employed (55.6%). Significant associations were found between ability to identify at least one correct risk factor and employability status (p = 0.029), single group (p = 0.036) and smokers (p < 0.001). In addition, significant associations were found between identifying at least one correct stroke symptom and smokers (p < 0.001) and no-obese people (p = 0.048). Furthermore, younger age group (below 30 years) were significantly able to list at least one correct stroke consequence compared to the older age groups (p = 0.025). Moreover, a significantly higher number of smokers compared to non-smokers correctly identified at least one stroke consequence (p = 0.019). The study revealed that there is a relatively weak understanding of the preventable nature of stroke among Syrian population. The overall awareness is still inadequate and varies depending on lifestyle factors and employment status.

Targeted surgery combined with postoperative medical therapy for residual disease for severe and multifocal Crohn’s disease

In patients with multifocal intestinal Crohn disease requiring surgery for complication or uncontrolled disease, resection of all the lesions may lead to diarrhea and malnutrition. This is a single-center retrospective review of all patients undergoing targeted surgery for multifocal Crohn disease with at least one residual Crohn disease location left behind. The primary endpoint was the rate of insufficient control of residual Crohn disease lesions requiring redo-surgery targeting these lesions. The rate of clinical remission defined by Harvey-Bradshaw index <4 was studied over time. From January 2012 to August 2022, among 320 patients undergoing surgery for intestinal Crohn disease, 30 metall criteria. Before surgery, patients had received a mean of 3 medical treatment lines; 83% (n= 25) had a clinically active Crohn disease (Harvey-Bradshaw index ≥4). Surgery consisted in ileocolonic (n= 14;47%), small bowel (n= 5;17%) or colonic resection (n= 12;40%) and strictureplasty (n= 4;13%). Operative mortality was nil. Overall postoperative and severe morbidity rates were 15 of 30 (50%) and 3 of 30. Residual lesions were in the small bowel (n= 15;50%), the colon (n= 16;53%), and/or the rectum (n= 16;53%). Twenty-five patients (83%) had postoperative medical therapy. Median follow-up was 65. Six patients (20%) required reoperation for insufficient control of residual lesions at index surgery after a mean of 98±8months. The clinical remission rate increased from 17% before surgery to 59% at 6-12months and 71% at 24months. In patients with multifocal Crohn disease, surgery targeted to severe and complicated lesions combined with postoperative medical treatment is a safe and effective strategy.

O-092 Prevalence of multiple gestation births and perinatal outcomes in pregnancies secondary to clomiphene citrate treatment: a nationwide cohort study

Abstract Study question Is the incidence of multiple gestation births higher in pregnancies obtained after clomiphene citrate (CC) treatment compared to spontaneous pregnancies? Summary answer The rate of multiple gestation births in pregnancies obtained after CC treatment is significantly increased compared to spontaneous pregnancies. What is known already CC is a selective estrogen modulator frequently used to induce ovulation in infertile women. Data regarding the prevalence of multiple gestation births and adverse perinatal outcomes after CC are contradicting and based on meta-analysis of small sample size studies. Multiple gestations are frequently associated with complications such as preeclampsia, premature labor, and growth restriction, which contribute to higher mortality and morbidity rates. Study design, size, duration Using the French National Health Data System (SNDS) spanning 2013 to 2019, we conducted a nationwide cohort study including all pregnancies lasting more than 22 weeks of gestation, in women aged between 18-43 years. Participants/materials, setting, methods For each women, the first pregnancy during study was included. Women with the dispensing of IVF/ICSI treatment and/or gonadotrophins were excluded. Pregnancies exposed to CC (during the period [-60days,-11days] before the beginning of the pregnancy) were 1:10 matched to unexposed pregnancies. Pregnancies exposed to CC between 12 to 2months or less than 11 days before the beginning of the pregnancy were excluded to mitigate misclassification bias. The primary outcome was the multiple gestation birth rate. Main results and the role of chance Of 3,173,013 pregnancies, 32,010 (10 ‰) occurred in women exposed to clomiphene. The multiple pregnancy rate was significantly higher in pregnant women exposed with CC compared to matched controls (odd ratio 4.1, 95% CI [3.9-4.3]) such as twin pregnancies (OR 4.1, 95% CI [3.9-4.3]) and triple or more pregnancies (OR 5.1, 95% CI [3.8-7.2]). Women exposed to CC presented significantly more adverse obstetrical and perinatal outcomes, including stillbirths, premature delivery threats, premature rupture of membranes, gestational diabetes, placenta previa, gravid hypertension, pre-eclampsia, preterm birth, small for gestational age (SGA), C-section rate, and major birth defect rate. After stratification on multiple pregnancy and adjustment on confounders (history of psychiatric disease, diabetes, arterial hypertension, obesity and embryo reduction during pregnancy), women exposed to CC had a significantly higher risk of stillbirth, gestational diabetes, placenta previa, pre-eclampsia, preterm delivery and SGA in case of singleton pregnancies. Additionally, in the case of multiple pregnancies, they had a higher risk of placenta previa, preterm delivery, and SGA compared to non-exposed women. Limitations, reasons for caution The use of filled prescriptions as a measure of drug exposure could be subject to bias such as misclassification bias, although we attempt to mitigate it. Wider implications of the findings Clomiphene use is strongly associated with multiple gestation births and with adverse obstetrical and perinatal outcomes even in singleton pregnancies. These findings should provide awareness of practitioners and patients about its use. It underscore the importance of attentively monitoring follicular growth during the treatment process to avoid multiple pregnancies. Trial registration number NA

Relationship between the Injury Location and Swallowing Difficulty among Stroke Patients, A Retrospective Cohort Study

Post-stroke dysphagia (PSD), a neurological or mechanical disorder that hinders food transport from the oral cavity to the stomach. It has been widely associated with severe complications with higher mortality and morbidity rates. Traditional therapies for the treatment of dysphagia mainly focused on compensatory methods and behavioural rehabilitation approaches. The retrospective cohort study aimed to determine the association and correlation between developments of dysphagia in relation to the location of the stroke and to identify the swallowing recovery period following the stroke. A retrospective cohort study investigated swallowing difficulties in 64 stroke patients at an ambulatory care centre over a year. Data collection involved reviewing medical records and imaging reports, with analyses conducted using SPSS software, ANOVA and chi-square methods to assess associations between injury location and swallowing difficulty. Hemorrhagic stroke was more prevalent (65.6%) than ischemic stroke (34.4%). A significant association was found between gender and stroke type, with males exhibiting a higher prevalence of ischemic strokes (71.4%) compared to females (29.8%). Age differences between stroke types, gender and affected swallowing phases and stroke type and affected swallowing phase revealed no significant associations. Distinct differences were noted in swallowing difficulties across stroke types. Furthermore, recovery time varied depending on the intervention method, with speech therapy linked to shorter recovery periods. The study underscores the importance of considering gender and stroke-type-specific differences in stroke prevalence, age distribution, and swallowing difficulties. These findings contribute valuable insights to understanding stroke characteristics and their implications for clinical management and rehabilitation strategies.
