Authors: Mingming Hu, Xiaomi Li, Haifeng Lin, Baohua Lu, Qunhui Wang, Li Tong, Hongxia Li, Nanying Che, Shaojun Hung, Yi Han, Kang Shi, Chenghai Li, Hongmei Zhang, Zhidong Liu, Tongmei Zhang
Journal: International Journal of Surgery (2024)

Background: Neoadjuvant chemoimmunotherapy (NACI) is promising for resectable nonsmall cell lung cancer (NSCLC), but predictive biomarkers are still lacking. The authors aimed to develop a model based on pretreatment parameters to predict major pathological response (MPR) for such an approach. Methods: The authors enrolled operable NSCLC treated with NACI between March 2020 and May 2023 and then collected baseline clinical-pathology data and routine laboratory examinations before treatment. The efficacy and safety data of this cohort was reported and variables were screened by Logistic and Lasso regression and nomogram was developed. In addition, receiver operating characteristic curves, calibration curves, and decision curve analysis were used to assess its power. Finally, internal cross-validation and external validation was performed to assess the power of the model. Results: In total, 206 eligible patients were recruited in this study and 53.4% (110/206) patients achieved MPR. Using multivariate analysis, the predictive model was constructed by seven variables, prothrombin time (PT), neutrophil percentage (NEUT%), large platelet ratio (P-LCR), eosinophil percentage (EOS%), smoking, pathological type, and programmed death ligand-1 (PD-L1) expression finally. The model had good discrimination, with area under the receiver operating characteristic curve (AUC) of 0.775, 0.746, and 0.835 for all datasets, cross-validation, and external validation, respectively. The calibration curves showed good consistency, and decision curve analysis indicated its potential value in clinical practice. Conclusion: This real world study revealed favorable efficacy in operable NSCLC treated with NACI. The proposed model based on multiple clinically accessible parameters could effectively predict MPR probability and could be a powerful tool in personalized medication.

Assessing the Ambulatory Surgery Center Volume-Outcome Association
Authors: Siddharth Jain, Paul R. Rosenbaum, Joseph G. Reiter, Omar I. Ramadan, Alexander S. Hill, Jeffrey H. Silber, Lee A. Fleisher
Journal: JAMA Surgery (2024)

Importance In surgical patients, it is well known that higher hospital procedure volume is associated with better outcomes. To our knowledge, this volume-outcome association has not been studied in ambulatory surgery centers (ASCs) in the US. Objective To determine if low-volume ASCs have a higher rate of revisits after surgery, particularly among patients with multimorbidity. Design, Setting, and Participants This matched case-control study used Medicare claims data and analyzed surgeries performed during 2018 and 2019 at ASCs. The study examined 2328 ASCs performing common ambulatory procedures and analyzed 4751 patients with a revisit within 7 days of surgery (defined to be either 1 of 4735 revisits or 1 of 16 deaths without a revisit). These cases were each closely matched to 5 control patients without revisits (23 755 controls). Data were analyzed from January 1, 2018, through December 31, 2019. Main Outcomes and Measures Seven-day revisit in patients (cases) compared with the matched patients without the outcome (controls) in ASCs with low volume (less than 50 procedures over 2 years) vs higher volume (50 or more procedures). Results Patients at a low-volume ASC had a higher odds of a 7-day revisit vs patients who had their surgery at a higher-volume ASC (odds ratio [OR], 1.21; 95% CI, 1.09-1.36; P = .001). The odds of revisit for patients with multimorbidity were higher at low-volume ASCs when compared with higher-volume ASCs (OR, 1.57; 95% CI, 1.27-1.94; P &amp;amp;lt; .001). Among patients with multimorbidity in low-volume ASCs, for those who underwent orthopedic procedures, the odds of revisit were 84% higher (OR, 1.84; 95% CI, 1.36-2.50; P &amp;amp;lt; .001) vs higher-volume centers, and for those who underwent general surgery or other procedures, the odds of revisit were 36% higher (OR, 1.36; 95% CI, 1.01-1.83; P = .05) vs a higher-volume center. The findings were not statistically significant for patients without multimorbidity. Conclusions and Relevance In this observational study, the surgical volume of an ASC was an important indicator of patient outcomes. Older patients with multimorbidity should discuss with their surgeon the optimal location of their care.

Towards Automation in 3D Cell Culture: Selective and Gentle High‐Throughput Handling of Spheroids and Organoids via Novel Pick‐Flow‐Drop Principle
Authors: Viktoria Zieger, Daniel Frejek, Stefan Zimmermann, Guilherme A. A. Miotto, Peter Koltay, Roland Zengerle, Sabrina Kartmann
Journal: Advanced Healthcare Materials (2024)

3D cell culture is becoming increasingly important for mimicking physiological tissue structures in areas such as drug discovery and personalized medicine. To enable reproducibility on a large scale, automation technologies for standardized handling are still a challenge. Here, a novel method for fully automated size classification and handling of cell aggregates like spheroids and organoids is presented. Using microfluidic flow generated by a piezoelectric droplet generator, aggregates are aspirated from a reservoir on one side of a thin capillary and deposited on the other side, encapsulated in free-flying nanoliter droplets to a target. The platform has aggregate aspiration and plating efficiencies of 98.1% and 98.4%, respectively, at a processing throughput of up to 21 aggregates per minute. Cytocompatibility of the method is thoroughly assessed with MCF7, LNCaP, A549 spheroids and colon organoids, revealing no adverse effects on cell aggregates as shear stress is reduced compared to manual pipetting. Further, generic size-selective handling of heterogeneous organoid samples, single-aggregate-dispensing efficiencies of up to 100% and the successful embedding of spheroids or organoids in a hydrogel with subsequent proliferation is demonstrated. This platform is a powerful tool for standardized 3D in vitro research.

The current status and challenges of perioperative management of patients with a BMI of greater than or equal to 50 kg/m2 undergoing bariatric surgery in China: a multicenter cross-sectional study
Authors: Ningli Yang, Hongxia Hua, Shaozhuang Liu, Songhai Zhang, Xiangwen Zhao, Peng Zhang, Pin Zhang, Yong Wang, Jiajia Shen, Shibo Lin, Wei Guan, Hui Liang
Journal: International Journal of Surgery (2024)

Background: Performing bariatric surgery on patients with a BMI of over 50 kg/m 2 is challenging. This study aimed to explore the status and challenges related to the perioperative management of such patients in China. Materials and methods: A prospective survey was designed to investigate the perioperative management of patients with a BMI of greater than or equal to 50 kg/m 2 undergoing bariatric surgery in China. The questionnaire of our survey included general information, preoperative management measures, surgical procedures performed, technical details regarding anaesthesia, and postoperative management measures. A response from only one attending physician per bariatric centre was accepted. Results: Physicians from a total of 101 hospitals responded to the questionnaire, and the questionnaire data from 98 hospitals were complete. These centres had completed a total of 44 702 bariatric surgeries since the launch of such surgery to December 2021. A total of 3280 patients had a BMI exceeding 50 kg/m 2 . The preferred surgical procedures for patients with super obesity were sleeve gastrectomy by 62 centres, Roux-en-Y gastric bypass by 11 centres, sleeve gastrectomy plus jejunojejunal bypass by 19 centres, one anastomosis gastric bypass by 1 centre, and duodenal switch by 1 centre. The most worrying issues were cardiopulmonary failure and difficulty in extubation. 91 centres believed that preoperative weight loss was beneficial. A low-calorie diet was the specific measure mainly implemented, only three centres considered using intragastric balloon placement. Postoperative management measures varied greatly. Conclusion: Bariatric surgery has seen rapid development. Chinese physicians show significant differences regarding the perioperative management for patients with a BMI of over 50 kg/m 2 . The perioperative risks of these patients remain relatively high, making further development of clinical pathways is necessary.

Authors: Sophia N. Wix, Ariel B. Brown, Meghan Heberton, Adewole S. Adamson, Jennifer G. Gill
Journal: JAMA Dermatology (2024)

Importance Melanoma in Black individuals has an annual incidence of approximately 1 in 100 000 people. Most studies of melanoma in Black patients have used population databases, which lack important, precise clinical details. Objective To identify patient-level and tumor-level characteristics of melanoma in Black patients. Design, Setting, and Participants This case series included Black patients with melanoma at 2 tertiary care centers (University of Texas Southwestern [UTSW] Medical Center and Parkland Health), affiliated with a single institution, UTSW in Dallas, Texas. Self-reported Black patients with a histopathologic diagnosis of melanoma were identified between January 2006 and October 2022. Main Outcomes and Measures The main variables were demographics, clinical characteristics, personal and family medical history, immunosuppression history, comorbidities, histopathology reports, molecular/genetic studies, imaging reports, melanoma treatments and responses, time to progression, metastatic sites, and survival rates. Results A total of 48 Black patients with melanoma (median [range] age at diagnosis, 62 [23-86] years; 30 [63%] female) were included in the study. Of 40 primary cutaneous melanomas, 30 (75%) were located on acral skin, despite only 10 of 30 (33%) being histologically classified as acral lentiginous melanomas. Compared with those with acral disease, patients with nonacral cutaneous melanomas were more likely to be immunocompromised (4 of 10 [40%] vs 2 of 30 [7%]) or have a personal history of cancer (6 of 10 [60%] vs 5 of 30 [17%]), with all 3 patients with superficial spreading melanoma having a history of both. No patients had more than 1 confirmed primary melanoma. Overall, 13 Black patients (27%) with melanoma developed stage IV disease, of whom 12 died because of disease progression. Those diagnosed with advanced acral melanoma, mucosal/ocular melanoma, or melanoma of unknown primary lacked actionable sequence variations, were nonresponsive to immunotherapy, and had the poorest outcomes. No patients with nonacral cutaneous melanomas developed distant metastases or died of melanoma. Conclusions and Relevance This single-institution case series highlights several features of melanoma in Black patients that have not been captured in existing population-level registries, including precise anatomic sites, immune status, family and personal cancer history, and genetics. Multi-institutional registries would improve understanding of melanoma in Black patients.
Meta-analysis reveals obesity associated gut microbial alteration patterns and reproducible contributors of functional shift
Authors: Deep Chanda, Debojyoti De
Journal: Gut Microbes (2024)

The majority of cohort-specific studies associating gut microbiota with obesity are often contradictory; thus, the replicability of the signature remains questionable. Moreover, the species that drive obesity-associated functional shifts and their replicability remain unexplored. Thus, we aimed to address these questions by analyzing gut microbial metagenome sequencing data to develop an in-depth understanding of obese host-gut microbiota interactions using 3329 samples (Obese, n = 1494; Control, n = 1835) from 17 different countries, including both 16S rRNA gene and metagenomic sequence data. Fecal metagenomic data from diverse geographical locations were curated, profiled, and pooled using a machine learning-based approach to identify robust global signatures of obesity. Furthermore, gut microbial species and pathways were systematically integrated through the genomic content of the species to identify contributors to obesity-associated functional shifts. The community structure of the obese gut microbiome was evaluated, and a reproducible depletion of diversity was observed in the obese compared to the lean gut. From this, we infer that the loss of diversity in the obese gut is responsible for perturbations in the healthy microbial functional repertoire. We identified 25 highly predictive species and 37 pathway associations as signatures of obesity, which were validated with remarkably high accuracy (AUC, Species: 0.85, and pathway: 0.80) with an independent validation dataset. We observed a reduction in short-chain fatty acid (SCFA) producers (several Alistipes species, Odoribacter splanchnicus, etc.) and depletion of promoters of gut barrier integrity (Akkermansia muciniphila and Bifidobacterium longum) in obese guts. Our analysis underlines SCFAs and purine/pyrimidine biosynthesis, carbohydrate metabolism pathways in control individuals, and amino acid, enzyme cofactor, and peptidoglycan biosynthesis pathway enrichment in obese individuals. We also mapped the contributors to important obesity-associated functional shifts and observed that these are both dataset-specific and shared across the datasets. In summary, a comprehensive analysis of diverse datasets unveils species specifically contributing to functional shifts and consistent gut microbial patterns associated to obesity.

Abstract Sepsis remains a major cause of mortality and morbidity worldwide. Algorithms that assist with the early recognition of sepsis may improve outcomes, but relatively few studies have examined their impact on real-world patient outcomes. Our objective was to assess the impact of a deep-learning model (COMPOSER) for the early prediction of sepsis on patient outcomes. We completed a before-and-after quasi-experimental study at two distinct Emergency Departments (EDs) within the UC San Diego Health System. We included 6217 adult septic patients from 1/1/2021 through 4/30/2023. The exposure tested was a nurse-facing Best Practice Advisory (BPA) triggered by COMPOSER. In-hospital mortality, sepsis bundle compliance, 72-h change in sequential organ failure assessment (SOFA) score following sepsis onset, ICU-free days, and the number of ICU encounters were evaluated in the pre-intervention period (705 days) and the post-intervention period (145 days). The causal impact analysis was performed using a Bayesian structural time-series approach with confounder adjustments to assess the significance of the exposure at the 95% confidence level. The deployment of COMPOSER was significantly associated with a 1.9% absolute reduction (17% relative decrease) in in-hospital sepsis mortality (95% CI, 0.3%–3.5%), a 5.0% absolute increase (10% relative increase) in sepsis bundle compliance (95% CI, 2.4%–8.0%), and a 4% (95% CI, 1.1%–7.1%) reduction in 72-h SOFA change after sepsis onset in causal inference analysis. This study suggests that the deployment of COMPOSER for early prediction of sepsis was associated with a significant reduction in mortality and a significant increase in sepsis bundle compliance.
