RESUMO
Social media has become omnipresent in society, especially given that it enables the rapid and widespread communication of news, events, and information. Social media platforms have become increasingly used by numerous surgical societies to promote meetings and surgical journals to increase the visibility of published content. In September 2020, Annals of Surgical Oncology (ASO) established its Social Media Committee (SMC), which has worked to steadily increase the visibility of published content on social media platforms, namely X (formerly known as Twitter). The purpose of this review is to highlight the 10 ASO original articles with the most engagement on X, based on total number of mentions, since the founding of the SMC. These articles encompass a wide variety of topics from various oncologic disciplines including hepatopancreatobiliary, breast, and gynecologic surgery.
RESUMO
CONTEXT.: Unlike parotid fine-needle aspiration biopsy, standardized reporting for core needle biopsy (CNB) and incisional biopsy (IB) is not established. OBJECTIVE.: To examine the value of risk stratification by a Milan System for Reporting Salivary Gland Cytopathology (MSRSGC)-like classifier for parotid CNB/IB. DESIGN.: Five hundred ninety-two parotid biopsy records (CNB = 356, IB = 236) were retrieved (1994-2022) along with clinicopathologic data. Diagnoses were transformed to an MSRSGC-like classifier and compared with end points including risk of malignancy. RESULTS.: Over time, CNB was progressively more used compared with IB. Overall malignancy call rate was 223 of 592 (37.7%). Common specific diagnoses included Warthin tumor, lymphoma subtypes, and metastatic squamous cell carcinoma for CNB and IB, in addition to pleomorphic adenoma for CNB. Descriptive diagnoses were still frequent. Nondiagnostic rates were higher in CNB (26 of 356; 7.30%) than IB (5 of 236; 2.12%; P <.001). Tissue volumes significantly influenced CNB adequacy, with minimum and optimal volumes of 4.76 mm³ (J index, receiver operating characteristic curve) and 12.92 mm³ (95th percentile of distribution), respectively. One hundred forty-four patients (112 CNBs) had follow-up resections; diagnoses were concordant for 66 of 73 adequate CNBs (90.41%). Our restructured risk grouping of MSRSGC categories performed robustly in terms of risk of malignancy (sensitivity = 85.5%, specificity = 100%, accuracy = 92.3%, area under the curve = 0.9677). CONCLUSIONS.: Although CNB and IB are amenable to a risk stratification system, there are some differences as compared with fine-needle aspiration biopsy, particularly given the high baseline prevalence of malignancy. Specific diagnoses are often feasible and concordant with resection. CNB tissue volume can inform optimal and minimal sampling recommendations for adequacy.
RESUMO
Background and aim: Childhood choking is a global health concern that mainly affects children under the age of 5 years. The parent's and caretaker's responsibility is critical in the children's lives and can potentially influence the result of at-home injuries such as choking. We aimed to assess the knowledge, attitude, practice, and associated factors of first aid management toward choking hazards among Saudi adults from the Eastern Province. Methods: The present analytical study was carried out among 390 Saudi adults attending different primary health centers in the Eastern Province of Saudi Arabia. We used a standard and validated data research topic tool to assess knowledge, attitude, and practice. Spearman's correlation was applied to determine the correlation between each section, while binomial logistic regression analysis was applied to identify the associated factors. Results: We observed knowledge, attitude, and practice scores in 43.3, 38.9, and 36.4% of the participants, respectively. Furthermore, positive correlations between knowledge and attitude (rho = 0.42, p = 0.001), between knowledge and practice (rho = 0.57, p = 0.001), and between attitude and practice (rho = 0.41, p = 0.001) were revealed in our survey. The knowledge of the participants was significantly higher with the age group of 30-40 years [adjusted odds ratio (AOR) = 3.67 (1.94-4.65), p = 0.001] and participants who received training in first aid management [AOR = 1.64 (1.12-2.49), p = 0.037]. This study found that males [AOR = 0.36 (0.21-0.63), p = 0.001] and those working in the private sector [AOR = 0.61 (0.31-0.87), p = 0.018] had significantly lower attitudes. Conclusion: Our results underscore the importance of continuous health education initiatives and training courses at primary health care centers regarding first aid management of choking hazards to improve awareness and practices. Furthermore, we recommend prospective multicenter studies to address region-specific knowledge gaps.

BACKGROUND: MYB RNA in situ hybridization (ISH) has emerged as a reliable and accessible marker to support adenoid cystic carcinoma (ACC) diagnosis, though still not well studied. Here, we report our results in a validation and prospective cohort to improve MYB RNA ISH diagnostic accuracy. METHODS: 79 cases (23 retrospective and 56 prospective) underwent MYB RNA ISH testing (44 ACC and 35 non-ACC). MYB RNA ISH results were initially interpreted based on previously established (original) scoring criteria. Weighted "i-scores", percent positive tumor cells, percent tumor cells with large signals (% LS), and staining pattern (abluminal, diffuse, focal non-patterned, or negative) were inputs for logistic regression models. Final model performance characteristics were compared with original scoring criteria and MYB::NFIB FISH results. RESULTS: An abluminal pattern was characteristic and exclusive to ACC. All i-scores, % LS, and percent positive were significantly higher in ACC. Original scoring criteria yielded a 95.5% sensitivity (Sn), 68.6% specificity (Sp), and 83.5% accuracy. MYB::NFIB FISH yielded a 42.9% sensitivity, 100% specificity, and 60% accuracy. Optimizing for performance, simplicity, and minimal collinearity, our final model was defined as: abluminal pattern and/or % LS > 16.5%, which resulted in a 93.2% Sn, 97.1% Sp, and 94.9% accuracy for ACC diagnosis. False negatives included an ACC with striking tubular eosinophilia and a MYBL1::NFIB translocated ACC. One false positive exclusive to the final model was a nasopharyngeal carcinoma with MYB amplification. CONCLUSIONS: MYB RNA ISH has a higher Sn than MYB::NFIB FISH while retaining high Sp. Our model provides improvements to specificity compared to original scoring criteria and highlight the importance of abluminal staining pattern and % LS. Nonetheless, alternate fusions remain key false negatives while rare non-ACC with other mechanisms of MYB activation may present as false positives.

Objective: Our aim was to assess whether complications after pancreatoduodenectomy (PD) impact long-term quality of life (QoL) and functional outcomes. Background: There is an increasing number of long-term post-PD survivors, but few studies have evaluated long-term QoL outcomes. Methods: The EORTC QLQ-C30 and QLQ-PAN26 questionnaires were administered to patients who survived >5 years post-PD. Clinical relevance (CR) was scored as small (5-10), moderate (10-20), or large (>20). Patients were stratified based on whether they experienced a complication during the index hospitalization. Results: Of 305 patients >5 years post-PD survivors, with valid contact information, 248 completed the questionnaires, and 231 had complication data available. Twenty-nine percent of patients experienced a complication, of which 17 (7.4%) were grade 1, 27 (11.7%) were grade 2, and 25 (10.8%) were grade 3. Global health status and functional domain scores were similar between both groups. Patients experiencing complications reported lower fatigue (21.4 vs 28.1, P < 0.05, CR small) and diarrhea (15.9 vs 23.1, P < 0.05, CR small) symptom scores when compared to patients without complications. Patients experiencing complications also reported lower pancreatic pain (38.2 vs 43.4, P < 0.05, CR small) and altered bowel habits (30.1 vs 40.7, P < 0.01, CR moderate) symptom scores. There was a lower prevalence of worrying (36.2% vs 60.5%, P < 0.05) and bloating (42.0% vs 56.2%, P < 0.05) among PD survivors with complications. Conclusions: Post-PD complication rates were not associated with long-term global QoL or functionality, and may be associated with less severe pancreas-specific symptoms.
RESUMO
Detection of extranodal extension on histopathology in surgically treated head and neck squamous cell carcinoma indicates poor prognosis. However, there is no consensus on the diagnostic criteria, interpretation, and reporting of histology detected extranodal extension, which has contributed to conflicting evidence in the literature, and likely clinical inconsistency. The Head and Neck Cancer International Group conducted a three-round modified Delphi process with a group of 19 international pathology experts representing 15 national clinical research groups to generate consensus recommendations for histology detected extranodal extension diagnostic criteria. The expert panel strongly agreed on terminology and diagnostic features for histology detected extranodal extension and soft tissue metastasis. Moreover, the panel reached consensus on reporting of histology detected extranodal extension and on nodal sampling. These consensus recommendations, endorsed by 19 organisations representing 34 countries, are a crucial development towards standardised diagnosis and reporting of histology detected extranodal extension, and more accurate data collection and analysis.

While acinic cell carcinoma (AciCC) can undergo high-grade transformation (HGT) to high-grade adenocarcinoma or poorly differentiated carcinoma, other morphologies such as spindle cell/sarcomatoid carcinoma are rare and not well-characterized. We herein report a novel case of AciCC with squamoglandular and chondrosarcomatous HGT mimicking a so-called 'carcinosarcoma ex-pleomorphic adenoma'. The patient is an 81-year-old male with a two-month history of neck swelling and referred otalgia who presented with a left parapharyngeal space mass extending into retropharyngeal space and pterygoid muscles. On resection, the tumor showed considerable morphologic diversity with high-grade serous and mucous acinar components as well as cribriform to solid apocrine-like components with comedonecrosis and squamous differentiation, all of which were embedded in a chondromyxoid background ranging from paucicellular and bland to a high-grade chondrosarcoma/pleomorphic sarcoma-like appearance. Only a minor conventional AciCC component was noted. Immunostains were negative for AR and only focally positive for GCDFP-15 arguing against a true apocrine phenotype, while PLAG1 and HMGA2 were negative arguing against an antecedent pleomorphic adenoma. On the other hand, SOX-10, DOG-1 and PAS after diastase highlighted serous acinar differentiation, and mucicarmine, and NKX3.1 highlighted mucous acinar differentiation. NR4A3 immunohistochemical staining and NR4A3 fluorescence in situ hybridization were positive in the carcinomatous and sarcomatoid components while sequencing analysis of both components revealed identical alterations involving TP53, PIK3CB, ARID1A, and STK11. This unique case warrants caution in designating all salivary sarcomatoid carcinomas with heterologous elements as part of the 'carcinoma ex-pleomorphic adenoma' family.

CONTEXT.: High-grade transformation, previously known as dedifferentiation, in salivary gland carcinoma and carcinosarcoma ex pleomorphic adenoma is a rare phenomenon. It is, however, clinically relevant and affects treatment and prognosis. OBJECTIVE.: To review the existing literature, describe the histologic and immunophenotypic features, and highlight the diagnostic criteria of high-grade transformation in various salivary gland carcinomas and carcinosarcoma; to review its effect on clinical presentation and prognosis; and to review relevant molecular characteristics and recent concepts and advances. DATA SOURCES.: Literature search in PubMed using key words such as "high-grade transformation," "dedifferentiation," and "carcinosarcoma" in salivary gland. Relevant articles were reviewed, and additional articles were curated from the references of these articles. CONCLUSIONS.: High-grade transformation occurs rarely but has a significant impact on prognosis and management. By microscopy, the high-grade area is usually a distinct nodule and shows solid and nested architecture, cellular atypia, high mitotic count, and necrosis. The molecular features are not well established. Carcinosarcoma almost always arises in a pleomorphic adenoma and likely follows an adenoma-carcinoma-sarcoma pathway.
RESUMO
CONTEXT.: Biomarker reporting has increasingly become a key component of pathology reporting, providing diagnostic, prognostic, and actionable therapeutic data for patient care. OBJECTIVE.: To expand and improve the College of American Pathologists (CAP) biomarker protocols. DESIGN.: We surveyed CAP members to better understand the limitations they experienced when reporting cancer biomarker results. A Biomarker Workgroup reviewed the survey results and developed a strategy to improve and standardize biomarker reporting. Drafts of new and revised biomarker protocols were reviewed in both print and electronic template formats during interactive webinars presented to the CAP House of Delegates. Feedback was collected, and appropriate revisions were made to finalize the protocols. RESULTS.: The first phase of the CAP Biomarker Workgroup saw the development of (1) a new stand-alone general Immunohistochemistry Biomarker Protocol that includes reporting for ER (estrogen receptor), PR (progesterone receptor), Ki-67, HER2 (human epidermal growth factor receptor 2), PD-L1 (programmed death ligand-1), and mismatch repair; (2) a new Head and Neck Biomarker Protocol that updates the prior 2017 paper-only version into an electronic template, adding new diagnostic and theranostic markers; (3) a major revision to the Lung Biomarker Protocol to streamline it and add in pan-cancer markers; and (4) a revision to the Colon and Rectum Biomarker Protocol to add HER2 reporting. CONCLUSIONS.: We have taken a multipronged approach to improving biomarker reporting in the CAP cancer protocols. We continue to review current biomarker reporting protocols to reduce and eliminate unnecessary methodologic details and update with new markers as needed. The biomarker templates will serve as standardized modular units that can be inserted into cancer-reporting protocols.
RESUMO
INTRODUCTION: Surgical societies provide a plethora of resources for trainees; however, these opportunities are often underused due to suboptimal guidance, sponsorship, or mentorship. Here, we present the Society of Asian Academic Surgeons (SAAS) experience in enhancing the trainee experience and engagement in a surgical society focused on professional development. MATERIALS AND METHODS: We conducted an interactive idea-generating session during the 2022 SAAS Conference with all Associate Members (trainees) present in Honolulu, HI. Recurrent themes, concepts, and ideas/suggestions were carefully considered when planning the next SAAS Conference in Baltimore, MD. We employed a more targeted approach to trainee engagement at the 2023 SAAS Conference, with breakout sessions geared toward various levels of trainees, in addition to increased social events and networking opportunities. We obtained feedback from trainees in attendance through an electronic survey and informal conversations with faculty and Associate Members. RESULTS: Opportunities for surgical subspecialty networking was the most well-received portion of our formal Career Development program. The majority of trainees in attendance were medical students or junior residents who valued the exposure to junior faculty and those in leadership positions at academic institutions. The addition of a group text for easy communication among trainees and informal social activities for Associate Member networking among themselves were crucial in improving the overall conference experience. CONCLUSIONS: Opportunities to maximize trainee engagement in surgical societies are heightened during in-person conferences. Targeted session topics, guided networking opportunities, and creating channels for easier communication along with more social events have enhanced the overall experience for aspiring and current surgical trainees.

OBJECTIVE: To determine the prevalence of clinical significance reporting in contemporary comparative effectiveness research (CER). BACKGROUND: In CER, a statistically significant difference between study groups may or may not be clinically significant. Misinterpreting statistically significant results could lead to inappropriate recommendations that increase health care costs and treatment toxicity. METHODS: CER studies from 2022 issues of the Annals of Surgery , Journal of the American Medical Association , Journal of Clinical Oncology , Journal of Surgical Research , and Journal of the American College of Surgeons were systematically reviewed by 2 different investigators. The primary outcome of interest was whether the authors specified what they considered to be a clinically significant difference in the "Methods." RESULTS: Of 307 reviewed studies, 162 were clinical trials and 145 were observational studies. Authors specified what they considered to be a clinically significant difference in 26 studies (8.5%). Clinical significance was defined using clinically validated standards in 25 studies and subjectively in 1 study. Seven studies (2.3%) recommended a change in clinical decision-making, all with primary outcomes achieving statistical significance. Five (71.4%) of these studies did not have clinical significance defined in their methods. In randomized controlled trials with statistically significant results, sample size was inversely correlated with effect size ( r = -0.30, P = 0.038). CONCLUSIONS: In contemporary CER, most authors do not specify what they consider to be a clinically significant difference in study outcome. Most studies recommending a change in clinical decision-making did so based on statistical significance alone, and clinical significance was usually defined with clinically validated standards.

BACKGROUND: Indeterminate thyroid cytopathology diagnoses represent differing degrees of risk that are corroborated by follow-up studies. However, traditional cytologic-histologic correlation may overestimate the risk of malignancy (ROM) because only a subset of cases undergo resection. Alternatively, some molecular tests provide probability of malignancy data to calculate the molecular-derived risk of malignancy (MDROM) and the positive call rate (PCR). The authors investigated MDROMs and PCRs of indeterminate diagnoses for individual cytopathologists as quality metrics. METHODS: This study was approved by the Department of Pathology Quality Improvement Program. Thyroid cytopathology diagnoses and ThyroSeq v3 results were retrieved for each cytopathologist for a 2-year period with at least 3 years of follow-up for the atypia of undetermined significance (AUS), follicular neoplasia (FN), and follicular neoplasia, oncocytic-type (ONC) cytopathologic diagnoses. MDROMs and PCRs were compared with reference ROMs and cytologic-histologic correlation outcomes. RESULTS: The overall MDROMs (and ranges for cytopathologists) for the AUS, FN, and ONC categories were 13.4% (range, 5.8%-20.8%), 28.1% (range, 22.1%-36.7%), and 27.0% (range, 19.5%-41.5%), respectively, and most individual cytopathologists' MDROMs were within reference ROM ranges. However, PCRs more effectively parsed the differences in cytopathologists' ROM performance. Although the overall PCRs were not significantly different across cytopathologists (p = .06), the AUS PCRs were quite different (p = .002). By cytologic-histologic correlation, six of 55 resected cases (10.9%) were falsely negative, and there were no false-positive cases. CONCLUSIONS: MDROMs and PCRs evaluate concordance with reference ROMs and with one another and provide individual feedback, which potentially facilitates quality improvement.

The objective of this study is to investigate the synchronization criteria under the sampled-data control method for multi-agent systems (MASs) with state quantization and time-varying delay. Currently, a looped Lyapunov-Krasovskii Functional (LKF) has been developed, which integrates information from the sampling interval to ensure that the leader system synchronizes with the follower system, resulting in a specific condition in the form of Linear Matrix Inequalities (LMIs). The LMIs can be easily solved using the LMI Control toolbox in Matlab. Finally, the proposed approach's feasibility and effectiveness are demonstrated through numerical simulations and comparative results.

Chili peppers pungent and spicy flavor is caused by capsaicin, which is one of their active components. As well as being an important aspect of fruit quality, the hot sensation is a key attribute linked to members of the Capsicum genus. Extraction is one of the most popular techniques for separating and purifying organic materials, but the technique must be quick, affordable, adaptable, efficient, and high performing. This review formulates the extraction of Capsaicin from chili peppers. The extraction methods used were solvent extraction (SE), ultrasound assisted extraction (UAE), microwave assisted extraction (MAE), enzymatic treatment, supercritical fluid extraction (SFE), solid phase microextraction (SPME), aqueous two phase system (ATPS) and liquid under pressure (PLE). The content of capsaicin in the extract was evaluated by using Thin Layer Chromatography (TLC), Fourier Transform Infrared Spectroscopy (FTIR) and High performance Liquid Chromatography (HPLC). The insecticidal activity of capsaicin in storage insects in food grains for shelf life enhancement and bio availability of capsaicinoids in terms of absorption, distribution, metabolism, and elimination were also discussed.

INTRODUCTION: The coronavirus pandemic has demonstrated profound issues with using the Internet to research health information. For patients recommended a complex operation, such as the Whipple pancreaticoduodenectomy, the quality of health information online has not been appraised. The objective of this study was to define the readability and content quality of YouTube search results for the Whipple pancreaticoduodenectomy. METHODS: The first 100 search results for "whipple procedure" less than 10 min long in English with audio and or text were transcribed. The Flesch-Kincaid Grade defined the reading grade level. High content quality videos were accredited by YouTube in accordance with principles specified by the National Academy of Medicine or mentioned the standard components for a surgical consent. The Anderson-Lau score is a composite of these consent criteria out of a maximum of 8/8. The simplicity of videos for patient education was defined by the DISCERN tool. RESULTS: The reading level of 23% of the top 100 search results met the American average (8th grade). Accreditation was present for 45% and associated with an earlier median search ranking (36 versus 68, P = 0.002) and more 5th-8th grade level material (70% versus 38%, P = 0.014). The median Anderson-Lau score was 3/8 (range = 0/8-7/8) with only 5% achieving 7/8. Only 4% were high quality per DISCERN. CONCLUSIONS: Although accredited videos were more readable, most videos, especially those targeting patients, were beyond the comprehension of the average American. Simpler and higher quality educational materials are needed to inform patients on Whipple pancreaticoduodenectomy beyond their date of clinical diagnosis or surgical consenting.

Background: To explore the neuropsychiatric symptoms, sleep disturbances, and sexual dysfunction in patients with long COVID syndrome, which can help in building better follow-up strategies for coronavirus disease 2019 (COVID-19) survivors. Material and methods: A cross-sectional research was undertaken at the premises of a psychiatry unit at a tertiary care unit in Karachi, Pakistan, between August 2022 and April 2023. All individuals aged 18 years or older, who had a history of contracting COVID-19 infection in the last 12 months presented to the department of Psychiatry with neuropsychiatric symptoms were recruited. Using a predefined questionnaire, data was collected from the participants. A linear logistic regression was used to find the impact of age, sex, hospitalization, and duration of home isolation on the likelihood of persistent neuropsychiatric symptoms or sexual dysfunction. Results: A total of 457 patients were included. It was found that individuals were less likely to experience neuropsychiatric symptoms as age increased (OR=0.968, 95% CI: 0.949-0.986, P=0.001). Females were 4.8 times more likely to experience neuropsychiatric symptoms than males, and the association was extremely significant (OR=4.851, 95% CI: 3.085-7.626, P<0.0001). An increase in age raised the odds of having sleep disturbances among the survivors by 2.7 times (OR=2.672, 95% CI: 2.654-2.684, P<0.0001). The odds of having sleep disturbances were three times more likely in female participants as compared to male participants (OR=3.00, 95% CI: 1.771-5.094, P<0.0001). Conclusion: The majority of the COVID-19 survivors are presenting with persistent neuropsychiatric and sexual symptoms in our setting. Therefore, it is necessary to maintain proper follow-up with the survivors of COVID-19 and counsel the patients to inform the family physician if these symptoms persist for longer than a month. Increasing such practices of regular follow-ups with COVID-19 survivors can help in detecting early neuropsychiatric and sexual changes.
RESUMO
Biphenotypic sinonasal sarcoma (BSNS) is a rare neoplasm of the sinonasal tract. These tumors show neural and myogenic differentiation and are characterized by PAX3 translocations. The immunophenotypic features reflect their dual differentiation. They are low-grade sarcomas that show monomorphic spindle cells in sheets, fascicles, and herringbone patterns and are positive for S100 and smooth muscle actin. These tumors are common in elderly female patients and have a locally aggressive course. High-grade presentation or transformation was not documented until recently. Total 3 BSNSs have now been documented in the literature and we report a fourth tumor with high-grade transformation 8 years after the initial presentation. We identify the morphologic and immunohistochemical features of the high-grade areas and we highlight the stark differences with the low-grade areas based on literature and our specimen. We also discuss the diagnostic challenges that may come up with such a presentation.
