RESUMO
Background: The Chinese Society of Clinical Oncology Artificial Intelligence System (CSCO AI) serves as a clinical decision support system developed utilizing Chinese breast cancer data. Our study delved into the congruence between breast cancer treatment recommendations provided by CSCO AI and their practical application in clinical settings. Methods: A retrospective analysis encompassed 537 breast cancer patients treated at the Second Affiliated Hospital of Anhui Medical University between January 2017 and December 2022. Proficient senior oncology researchers manually input patient data into the CSCO AI system. "Consistent" and "Inconsistent" treatment categories were defined by aligning our treatment protocols with the classification system in the CSCO AI recommendations. Cases that initially showed inconsistency underwent a second evaluation by the Multi-Disciplinary Treatment (MDT) team at the hospital. Concordance was achieved when MDTs' treatment suggestions were in the 'Consistent' categories. Results: An impressive 80.4% concurrence was observed between actual treatment protocols and CSCO AI recommendations across all breast cancer patients. Notably, the alignment was markedly higher for stage I (85.02%) and stage III (88.46%) patients in contrast to stage II patients (76.06%, P=0.023). Moreover, there was a significant concordance between invasive ductal carcinoma and lobular carcinoma (88.46%). Interestingly, triple-negative breast cancer (TNBC) exhibited a high concordance rate (87.50%) compared to other molecular subtypes. When contrasting MDT-recommended treatments with CSCO AI decisions, an overall 92.4% agreement was established. Furthermore, a logistic multivariate analysis highlighted the statistical significance of age, menstrual status, tumor type, molecular subtype, tumor size, and TNM stage in influencing consistency. Conclusion: In the realm of breast cancer treatment, the alignment between recommendations offered by CSCO AI and those from MDT is predominant. CSCO AI can be a useful tool for breast cancer treatment decisions.
RESUMO
Sclerosing mesenteritis (SM) is a rare inflammatory disorder characterized by chronic inflammation and fibrosis of the mesenteric adipose tissue. While SM can manifest with various gastrointestinal symptoms, its association with small bowel obstruction (SBO) is infrequent. We present a case of a 78-year-old male with a history of systemic lupus erythematosus (SLE) who presented with acute abdominal pain and distention. The patient had multiple admissions with the same symptoms. A CT scan showed swirling of the proximal central mesentery, small bowel malrotation with volvulus, and high-grade mechanical obstruction of the proximal jejunum. The patient underwent exploratory laparotomy, with findings significant for multiple inflammatory nodules in the mesentery. These were causing adhesions between the bowel and mesentery, resulting in a volvulus of the bowel. One segment was resected, and subsequent histopathological examination revealed subserosal fibrosis and chronic inflammation. The clinical scenario was consistent with a diagnosis of SM. This case highlights the challenges of diagnosing and managing SBO in the presence of SM and SLE. Further research is needed to understand the underlying pathophysiological mechanisms and improve management techniques for this rare clinical condition.
RESUMO
Objective: To develop and evaluate a nomogram prediction model for recurrence of acute ischemic stroke (AIS) within one year. Method: Patients with AIS treated at the second affiliated hospital of Xuzhou Medical University from August 2017 to July 2019 were enrolled. Clinical data such as demographic data, risk factors, laboratory tests, TOAST etiological types, MRI features, and treatment methods were collected. Cox regression analysis was done to determine the parameters for entering the nomogram model. The performance of the model was estimated by receiver operating characteristic curves, decision curve analysis, calibration curves, and C-index. Result: A total of 645 patients were enrolled in this study. Side of hemisphere (SOH, Bilateral, HR = 0.35, 95 % CI = 0.15-0.84, p = 0.018), homocysteine (HCY, HR = 1.38, 95 % CI = 1.29-1.47, p < 0.001), c-reactive protein (CRP, HR = 1.04, 95 % CI = 1.01-1.07, p = 0.013) and stroke severity (SS, HR = 3.66, 95 % CI = 2.04-6.57, p < 0.001) were independent risk factors. The C-index of the nomogram model was 0.872 (se = 0.016). The area under the receiver operating characteristic (ROC)curve at one-year recurrence was 0.900. Calibration curve, decision curve analysis showed good performance of the nomogram. The cutoff value for low or high risk of recurrence score was 1.73. Conclusion: The nomogram model for stroke recurrence within one year developed in this study performed well. This useful tool can be used in clinical practice to provide important guidance to healthcare professionals.
RESUMO
BACKGROUND: A greater emphasis has been placed on the part of cell cycle progression (CCP) in cancer in recent years. Nevertheless, the precise connection between CCP-related genes and bladder cancer (BCa) has remained elusive. This study endeavors to establish and validate a reliable risk model incorporating CCP-related factors, aiming to predict both the prognosis and immune landscape of BCa. METHODS: Clinical information and RNA sequencing data were collected from the GEO and TCGA databases. Univariate and multivariate Cox regression analyses were conducted to construct a risk model associated with CCP. The performance of the model was assessed using ROC and Kaplan-Meier survival analyses. Functional enrichment analysis was employed to investigate potential cellular functions and signaling pathways. The immune landscape was characterized using CIBERSORT algorithms. Integration of the risk model with various clinical variables led to the development of a nomogram. RESULTS: To build the risk model, three CCP-related genes (RAD54B, KPNA2, and TPM1) were carefully chosen. ROC and Kaplan-Meier survival analysis confirm that our model has good performance. About immunological infiltration, the high-risk group showed decreased levels of regulatory T cells and dendritic cells coupled with increased levels of activated CD4 + memory T cells, M2 macrophages, and neutrophils. Furthermore, the nomogram showed impressive predictive power for OS at 1, 3, and 5 years. CONCLUSION: This study provides new insights into the association between the CCP-related risk model and the prognosis of BCa, as well as its impact on the immune landscape.
RESUMO
Background Bariatric surgeries aid weight loss in patients with morbid obesity, yet staple-line leaks pose safety concerns. Multiple methods are used to help identify these links. Intraluminal indocyanine green (ICG) has been shown to be useful in other applications, and its use in robotic bariatric surgeries is underexplored. Objective The primary objective of this research project was to demonstrate the usage of intraluminal ICG in detecting staple-line leaks during robotic sleeve gastrectomy and robotic gastric bypass. Settings The research was conducted at Bronxcare Health System between June 2022 and June 2023. Methods We studied 150 consecutive participants undergoing robotic sleeve gastrectomy or robotic gastric bypass. Intraluminal ICG was used in each case in order to identify leaks. Data on comorbidities, detected intraoperative leaks, and detected postoperative leaks were collected. Results Out of the 150 patients who underwent robotic bariatric surgeries (139 for sleeve gastrectomy and 11 for gastric bypass), four cases (two for each procedure) were identified with intraoperative leaks using ICG, resulting in an overall 2.66% incidence rate. In those four patients with intraoperative leaks, reinforcing sutures and a drain were placed. Following the surgeries, none of the patients had radiologic or clinical leaks identified. Conclusions Intraluminal ICG presents a novel approach for detecting staple-line leaks in robotic bariatric surgery. Future studies can be done to look at a larger series of patients and compare leak detection rates between ICG and other methods.
RESUMO
Background and aim: Laryngopharyngeal reflux disease (LPRD) is primarily characterized by discomfort in the pharynx and has limited treatment options. This research aimed to assess the efficacy of transcutaneous auricular vagus nerve stimulation (tVNS) in patients with LPRD and delve into the potential underlying mechanisms. Methods: A total of 44 participants, diagnosed with LPRD were divided into two groups randomly. Twice-daily stimulation was delivered for 2 weeks for patients in experimental group, with stimulation ranging from 1.0 mA to 1.5 mA (n = 22), while the control group underwent sham tVNS (n = 22) with the same stimulation parameters and different anatomical location. The severity of symptoms and levels of anxiety and depression were monitored using questionnaires. High-resolution esophageal manometry data were collected, and the patients' autonomic function was assessed through heart rate variability analysis. Results: There was a positive correlation between reflux symptom index (RSI) scores and low frequency/high frequency (LF/HF) ratio (r = 0.619; p < 0.001), Hamilton anxiety scale (HAMA) scores (r = 0.623; p < 0.001), and Hamilton depression scale (HAMD) scores (r = 0.593; p < 0.001). Compared to the pre-tVNS phase, RSI (p < 0.001), HAMA (p < 0.001), and HAMD (p < 0.001) scores were significantly reduced after 2 weeks of treatment. Additionally, the resting pressure of the upper esophageal sphincter (UESP; p < 0.05) and lower esophageal sphincter (LESP; p < 0.05) showed significant enhancement. Notably, tVNS led to an increase in root mean square of successive differences (RMSSD; p < 0.05) and high frequency (HF; p < 0.05) within heart rate variability compared to the pre-treatment baseline. Compared to the control group, RSI (p < 0.001), HAMA (p < 0.001), and HAMD (p < 0.001) scores in tVNS group were significantly lower at the end of treatment. Similarly, the resting pressure of UESP (p < 0.05) and LESP (p < 0.05) in tVNS group were significantly higher than that of control group. Notably, RMSSD (p < 0.05) and HF (p < 0.05) in tVNS group were significantly higher than that of control group. Conclusion: This study demonstrated that tVNS as a therapeutic approach is effective in alleviating LPRD symptoms. Furthermore, it suggests that improvements in esophageal motility could be associated with vagus nerve-dependent mechanisms.
RESUMO
OBJECTIVES: To develop a model that can assist in the diagnosis and prediction of prognosis for head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS: Data from TCGA and GEO databases were used to generate normalized gene expression data. Consensus Cluster Plus was used for cluster analysis and the relationship between angiogenesis-associated gene (AAG) expression patterns, clinical characteristics and survival was examined. Support vector machine (SVM) and least absolute shrinkage and selection operator (LASSO) analyzes and multiple logistic regression analyzes were performed to determine the diagnostic model, and a prognostic nomogram was constructed using univariate and multivariate Cox regression analyses. ESTIMATE, XCELL, TIMER, QUANTISEQ, MCPCOUNTER, EPIC, CIBERSORT-ABS, CIBERSORT algorithms were used to assess the immune microenvironment of HNSCC patients. In addition, gene set enrichment analysis, treatment sensitivity analysis, and AAGs mutation studies were performed. Finally, we also performed immunohistochemistry (IHC) staining in the tissue samples. RESULTS: We classified HNSCC patients into subtypes based on differences in AAG expression from TCGA and GEO databases. There are differences in clinical features, TME, and immune-related gene expression between two subgroups. We constructed a HNSCC diagnostic model based on nine AAGs, which has good sensitivity and specificity. After further screening, we constructed a prognostic risk signature for HNSCC based on six AAGs. The constructed risk score had a good independent prognostic significance, and it was further constructed into a prognostic nomogram together with age and stage. Different prognostic risk groups have differences in immune microenvironment, drug sensitivity, gene enrichment and gene mutation. CONCLUSION: We have constructed a diagnostic and prognostic model for HNSCC based on AAG, which has good performance. The constructed prognostic risk score is closely related to tumor immune microenvironment and immunotherapy response.

The efficacy of intraoperative esophagogastroduodenoscopy (EGD) in visualizing a patient's small bowel interior to detect injuries or lesions, or conduct a leak test post-bowel anastomosis, makes it a preferred option among surgeons. However, it is not always available, can carry a risk of morbidity and mortality, or can prolong operative time if not performed by a proficient team. A 21-year-old male patient came to the emergency department with four gunshot wounds to his abdomen, with two on either side of the abdomen. Exploratory laparotomy was performed and through and through injuries were identified in the small bowel and at the junction of the third/fourth portion of the duodenum. It was challenging to gather the patient's past medical history, particularly gastrointestinal bleeding history, due to the underlying medical condition. However, the patient had experienced a retroperitoneal bowel injury in the setting of duodenal hematoma that was not immediately identified at first glance. In this context, intraoperative endoscopy could be a significant adjunct to detect retroperitoneal bowel injury if rapidly available and in a controlled scenario. Moreover, the advantages of intraoperative EGD increase with positive collaboration between a general surgeon and a gastroenterologist.
RESUMO
PURPOSE: The relationship between varicella zoster virus (VZV) infection and the risk of dementia has not been previously studied specifically. Therefore, this study sought to determine the relationship between studying VZV infection and dementia occurring in the general population by conducting an extensive meta-analysis of published cases. METHOD: A systematic literature search was conducted in seven online databases by October 31, 2022. Heterogeneity was tested by the I2 index. Pooled HR and 95% CI were used to estimate the effect of VZV infection on dementia. Sensitivity analyses and publication bias were also performed. RESULT: Nine studies involving 3,326,673 subjects were included. VZV infection was associated with an increased risk of dementia (HR = 1.11, 95% CI: 1.02-1.21). The risk of dementia was reduced in those who received antiviral therapy compared to those who did not (HR = 0.84, 95% CI: 0.71-0.99). In addition, VZV infection was found to be associated with an increased risk of developing dementia in the pooled results of the moderate quality study (HR = 1.81,95% CI: 1.27-2.59), and this association persisted when subgroup analyses were performed based on region (Asia: HR = 1.18,95% CI: 1.04-1.33). CONCLUSIONS: Our results suggest that VZV infection might increase the risk of developing dementia, but there is no clear mechanism about the true relationship, and since there is no effective treatment for dementia, and our results suggest that some populations can benefit from antiviral therapy, it is at least arguable that patients who develop VZV infection should be treated with appropriate antiviral medications.

Inguinal hernia is amongst the most common acute abdominal disease that presents in the Emergency Department (ED). Pathologically, it involves the displacement and herniation of abdominal, pelvic, or groin tissue through weaknesses in the abdominal wall. Many inguinal hernias are simple and asymptomatic, managed conservatively without the need for surgical intervention. However, under rare circumstances, hernias are susceptible to significant complications requiring emergent surgery. This report follows the case of a 61-year-old Hispanic-American male presenting to the ED with signs of a complex strangulated inguinal hernia and consequent infarction of the testis with Fournier's Gangrene. Clinical evaluation elucidated a one-week worsening abdominal pain, non-reducible painful inguinal hernia, nausea, vomiting, constipation, groin discoloration, dysuria, and a history of failed primary hernia repair during childhood. The patient underwent emergent surgery to excise ischemic-necrotic portions of the sigmoid colon, creation of end-colostomy, non-mesh repair of inguinal hernia, and right-sided complete orchiectomy with the removal of adjacent scrotal-Dartos tissues and spermatic cord due to Fournier's Gangrene. This report provides both a report for a potentially preventable consequence in one of the most common surgical presentations and a review of the multi-disciplinary expertise that is required in the surgical management of complex inguinal hernias.
RESUMO
INTRODUCTION AND IMPORTANCE: Primary splenic lymphoma (PSL) is characterized by lymphoma involvement confined to the spleen and hilar lymph nodes, without evidence of liver involvement or other sites. This condition is extremely uncommon, accounting for approximately 1 % of non- Hodgkin lymphomas (NHLs) and <2 % of all lymphomas. Diffuse large B-cell lymphoma (DLBCL) is the most common histological subtype of both PSLs and all NHLs. DLBCL encompasses an aggressive heterogeneous entity with distinct morphological variants. CASE PRESENTATION: A 68 year-old gentleman presented to the office with a 10-month history of vague left sided upper abdominal pain. Clinical examination revealed a tender left upper quadrant, evidenced with splenomegaly on radiological evaluation. The patient proceeded with a splenectomy with subsequent pathological and immunohistochemical analysis, confirming a final diagnosis of germinal center type DLBCL. CLINICAL DISCUSSION: Primary splenic DLBCL is a rare variant of DLBCL, characterized by exclusive involvement of the spleen. It requires a comprehensive diagnostic evaluation to exclude lymphoma involvement in other organs and lymph nodes. Splenectomy followed by appropriate adjuvant therapy has been demonstrated as the definitive treatment strategy. This case report emphasizes the importance of considering primary splenic DLBCL as a differential diagnosis in patients presenting with splenomegaly and highlights the significance of multidisciplinary collaboration for accurate diagnosis and optimal management of this uncommon entity. CONCLUSION: Primary Splenic DLBCL, an exceptionally rare B-Cell neoplasm variant, requires precise diagnosis due to its unique splenic involvement. Splenectomy's efficacy, adjuvant therapy, multidisciplinary collaboration, and ongoing research are crucial for optimal management.
RESUMO
BACKGROUND: Participation in colonoscopies is an essential aspect of endoscopic training. The purpose of this study was to explore the impact of fellow/trainee participation on colonoscopy outcomes. METHODS: This meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO). From database inception to July 2022, studies investigating fellow involvement and colonoscopy outcomes were searched across Cochrane library, PubMed, and other databases. The random-effects model was applied to generate more conservative estimates. Sensitive analysis was conducted to explore whether the result would depend on a particular study. Egger's test and Begg's test were used to estimate the potential for publication bias. RESULTS: Seventeen studies including 30,062 participants were included. We found that fellow/trainee involvement enhanced the overall rates of adenoma detection and polyp detection (OR = 1.26, 95% CI = 1.14-1.40, p < 0.001; OR = 1.29, 95% CI = 1.02-1.63, p = 0.020, respectively). The mean number of adenoma/polyps per colonoscopy was also higher with fellow/trainee participation (MD = 0.12, 95% CI = 0.08-0.17, p < 0.001; MD = 0.15, 95% CI = 0.02-0.28, p = 0.020, respectively). CONCLUSION: In addition to its educational purpose, fellow or trainee involvement is associated with beneficial effects on colonoscopy outcomes.

Radiation enteritis poses a treatment challenge for patients undergoing or completing radiation therapy. A significant issue has been the patient's and surgeon's lack of awareness of the condition and the radiotherapy or associated surgical treatments. A 66-year-old female presented with acute onset of diffuse abdominal pain and peritonitis for one day, status post radiation therapy following a diagnosis of cervical cancer. A review of systems was positive for diffuse sweating, chills, and nausea. The patient was diagnosed with an entero-colonic fistula with mesenteric edema. An entero-colonic fistula due to radiation enterocolitis is a rare but important complication that can occur after radiation therapy for abdominal or pelvic malignancies. With any patient who has a history of abdominal or pelvic cancer and has received radiotherapy and shows up with acute abdomen, bowel perforation should be considered in the differential diagnosis with the possible management of acute complications.
RESUMO
Objectives: The aim of this study was to investigate the association between diabetes status and the risk of breast cancer among adult Americans, exploring the impact of BMI, age, and race on this relationship. Methods: A cross-sectional analysis of 8,249 individuals from the National Health and Nutrition Examination Survey (NHANES) was conducted. Diabetes was categorized as type 2 diabetes and prediabetes, with both conditions diagnosed according to the ADA 2014 guidelines. The association between diabetes status and breast cancer risk was explored using multiple logistic regression analysis. Results: Patients with diabetes had higher odds of breast cancer (OR: 1.51; 95% CI 1.00 to 2.28), Using the two-piecewise linear regression model, it was observed that there is a threshold effect in the risk of breast cancer occurrence at the age of 52 years. Specifically, the risk of breast cancer is relatively low before the age of 52 but increases significantly after this age. Conclusions: This study identified a significant association between diabetes status and breast cancer risk among adult Americans. We also found a threshold effect in breast cancer occurrence at the age of 52. Age was significantly associated with breast cancer risk in both Non-Hispanic White and Non-Hispanic Black individuals. These findings underscore the importance of diabetes management, maintaining a healthy BMI, and age-related risk considerations in reducing breast cancer risk.

PURPOSE: Physical activity (PA) has been suggested to reduce the risk of cancer. However, previous studies have been inconsistent regarding the relationship between PA and the risk of developing gastric cancer (GC). The purpose of this study was to evaluate the impact of PA on the incidence and mortality risk of GC through a meta-analysis, as well as investigate potential dose-response relationships. METHODS: A systematic literature search was conducted in 10 electronic databases and 4 registries. The combined relative risks (RRs) were calculated using a random-effects model with 95% confidence interval (CIs) to assess the effect of PA on the risk of GC. Relevant subgroup analyses and sensitivity analyses were performed. RESULTS: The results showed that PA correlated with lower incidence of GC (RR: 0.83, 95% CI: 0.77-0.90), decreased risk of GC mortality (RR: 0.76, 95% CI: 0.66-0.89). The results of the subgroup analysis showed that PA was associated with reduced incidence of GC across gender, different regions, study designs, different sites of GC and different types of PA. A linear relationship was found for frequency of PA. CONCLUSIONS: This meta-analysis found that PA was associated with a reduced risk of GC incidence and mortality. The correlation between PA and GC occurrence was in a dose-response relationship.

BACKGROUND: Frailty is a complex geriatric syndrome caused by degenerative changes in the body or various chronic diseases. The use of personal care and consumer products is associated with a wide range of health outcomes, but its relationship with frailty remains unknown. Therefore, our primary aim was to explore the potential links between exposure to phenols and phthalates, either separately or in combination, and frailty. METHODS: The exposure levels of phthalates and phenols were evaluated through the measurement of metabolites in urine samples. Frailty state was assessed by a 36-item frailty index with values ≥ 0.25 indicating frailty. Weighted logistic regression was used to explore the relationship between individual chemical exposure and frailty. In addition, multi-pollutant strategies (WQS, Qgcomp, BKMR) were used to examine the joint effect of chemical mixture on frailty. A series of subgroup analyses and sensitivity analyses were conducted as well. RESULTS: In the multivariate logistic regression model, each unit increase in natural log-transformed BPA (OR: 1.21; 95%CI: 1.04, 1.40), MBP (OR: 1.25; 95%CI: 1.07, 1.46), MBzP (OR: 1.18; 95%CI: 1.03, 1.36), and MiBP (OR: 1.19; 95%CI: 1.03, 1.37) were significantly associated with higher odds of frailty. The results of the WQS and Qgcomp indicated that increasing quartiles of chemical mixture was associated with odds of frailty with ORs of 1.29 (95%CI: 1.01, 1.66) and 1.37 (95%CI: 1.06, 1.76). The weight of MBzP is dominant in both the WQS index and the positive weight of Qgcomp. In the BKMR model, the cumulative effect of chemical mixture was positively correlated with the prevalence of frailty. CONCLUSIONS: In summary, higher levels of BPA, MBP, MBzP, and MiBP are significantly associated with higher odds of frailty. Our study provides preliminary evidence that phenol and phthalate biomarker mixture is positively associated with frailty, with MBzP contributing most to the positive association.

RESUMO
Objectives: The aim of this study was to determine whether, on the day of human chorionic gonadotropin (hCG) injection, the progesterone to number of mature oocytes index (PMOI) can be used alone or together with other parameters in a fresh embryo transfer in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycle to predict pregnancy outcome. Methods: This was a retrospective cohort study of all couples who underwent a clinical pregnancy and received a fresh IVE/ICSI cycle at a single large reproductive medical center between June 2019 and March 2022. The study involved a total of 1239 cycles. To analyze risk factors associated with pregnancy outcomes on the day of HCG injection, univariate and multivariate logistic regression analyses were used. The area under the curve (AUC) was determined, and PMOI and other factors were compared using receiver operating characteristic (ROC) curves. Results: The clinical pregnancy rate was significantly higher in group A (60.76%) than in the other groups (Group B: 52.92% and Group C:47.88%, respectively, p =0.0306). Univariate and multivariate logistic regression revealed that PMOI levels were significantly correlated with the probability of pregnancy outcome, independent of other risk factors. More importantly, PMOI levels independently predict the occurrence of pregnancy outcome, comparable to the model combining age. The optimal serum PMOI cutoff value for pregnancy outcome was 0.063 ug/L. Conclusion: Our results suggest that PMOI levels have an independent predictive value for pregnancy outcome in fresh IVF/ICSI cycles.
