Loco-Regional Ropivacaine Analgesia Via a Surgically Placed Intercostal Catheter after Anatomic Lung Resection: Prospective, Placebo-Controlled, Double-Blind; Randomized Superiority Trial

Abstract Background Even after minimally invasive anatomic lung resection, pain remains a burden for patients. Current guidelines recommend the surgical placement of intercostal catheters at the end of the surgery to promote faster recovery after lung surgery. Aims The aim of this trial was to investigate the analgesic efficacy of continuous loco-regional application of ropivacaine via an intercostal catheter and to establish this method as a possible standard of care in postoperative analgesia management. Methods Between December 2021 and October 2023, we evaluated the efficacy of surgically inserted intercostal catheters. Patients were eligible when undergoing anatomic VATS lung resection under general anesthesia for confirmed or suspected stage I lung cancer (UICC, 8th edition). Patients received ropivacaine at a concentration of 2 mg/ml or a placebo through an elastomer pump, flow rate of 6-8 ml/h for 72 hours after surgery. The sample size was calculated to find an NRS (numerical rating scale) difference associated with a pain reduction of 1.5 points. Results 14 patients were randomly included in the ropivacaine group and 18 in the placebo group. The patients’ characteristics and preoperative pain scores were similar in both groups. Between the observed groups there was no statistically significant difference in postoperative pain scores and morphine consumption. The NRS score for cough 24 hours postoperatively was 4.9 (±2.2) in the ropivacaine group and 4.3 (±2.4); p=0.474 in the placebo group. In addition, we were unable to determine any influence of the pain management on the relative postoperative pulmonary function. Conclusion Our results suggest that the analgesic efficacy of continuous loco-regionally applied ropivacaine administered through a surgically placed intercostal catheter after surgery does not have a positive effect on postoperative pain scores or morphine requirements. Instead, local analgesia started at the beginning of the procedure and covering several intercostal spaces should be considered.

Weighing the gold standard: The breadth of emergency medicine core content covered by textbooks.

Textbooks are often considered the criterion standard in medical education, but there is a growing preference for free open-access medical education (FOAM) content among learners. Despite FOAM's appeal, these resources often fall short in covering core content as comprehensively as the American Board of Emergency Medicine's 2019 Model of the Clinical Practice of Emergency Medicine (MCPEM), thereby sustaining the recommendation for textbook use. However, textbooks have limitations, such as how quickly content can become outdated. Notably, there is no evaluation of the comprehensiveness of emergency medicine (EM) textbooks in the literature. This observational cross-sectional study compared Rosen's Emergency Medicine: Concepts and Clinical Practice 10th Edition (Rosen's) and Tintinalli's Emergency Medicine: A Comprehensive Study Guide 9th Edition (Tintinalli's) with the MCPEM subtopics. Each textbook chapter was reviewed for content alignment with MCPEM subtopics. The primary outcome was the proportion of MCPEM subtopics covered by each textbook. Secondary outcomes included the count of chapters covering each topic and their distribution relative to the core content weighting in the ABEM National Qualifying Examination (NQE). Rosen's covered 95.3% of MCPEM subtopics (837 unique subtopics), and Tintinalli's covered 94.5% (826 unique subtopics). Both textbooks overrepresented topics like toxicology and psychobehavioral disorders compared to their weighting in the NQE. Relatively underrepresented topics included environmental disorders, cardiovascular disorders, renal and urogenital disorders, and traumatic disorders in Rosen's and other core competencies and cardiovascular disorders in Tintinalli's. The textbooks varied significantly in coverage of certain topics. Both Rosen's and Tintinalli's comprehensively cover MCPEM subtopics, with some discrepancies in topic representation compared to the NQE. While textbooks offer depth and breadth, they may not fully align with the NQE content distribution. A diversified approach to EM education, combining traditional textbooks and FOAM resources may be required for comprehensive learning.

Interpretation of the pathological diagnostic criteria and characteristics of high-grade thyroid follicular-derived carcinoma in the 5th edition WHO classification

The 5th edition WHO classification of thyroid tumors proposed high-grade non-anaplastic thyroid carcinoma, which includes traditional poorly differentiated thyroid carcinoma (PDTC) and differentiated high-grade thyroid carcinoma (DHGTC), with a prognosis between highly differentiated thyroid carcinoma and anaplastic thyroid carcinoma (ATC), in which about 50% of patients do not take radioactive iodine. Therefore, this classification is of great clinical significance. This article interprets the diagnostic criteria and genetic features of high-grade non-anaplastic thyroid carcinoma in 5th edition WHO classification, comparing with ATC.

Beyond omission: analysing the erasure of disability and inclusion in the developmentally appropriate practices

ABSTRACT The 4th edition of the National Association for the Education of Young Children’s (NAEYC) guidelines for developmentally appropriate practice (DAP) had an opportunity to provide the field an inclusive blueprint. While there was an attempt in this edition to respond to decades of critiques (e.g. Bloch [1992]. “Critical Perspectives on the Historical Relationship Between Child Development and Early Childhood Education Research.” In Reconceptualizing the Early Childhood Curriculum: Beginning the Dialogue, edited by S. Kessler, and E. B. Swadener, 3–20. New York, NY: Teachers College Press.; Cannella [1997]. Deconstructing Early Childhood Education: Social Justice and Revolution. New York, NY: Peter Lang.; Escayg [2019]. “Who’s got the Power?”: A Critical Examination of the Anti-Bias Curriculum.” International Journal of Child Care and Education Policy 13 (1): 1–18. https://doi.org/10.1186/s40723-019-0062-9.; Langford [2010]. “Critiquing Child-Centered Pedagogy to Bring Children and Early Childhood Educators Into the Center of a Democratic Pedagogy.” Contemporary Issues in Early Childhood 11 (1): 113–127. https://doi.org/10.2304/ciec.2010.11.1.113.; Pérez and Saavedra [2017]. “A Call for Onto-Epistemological Diversity in Early Childhood Education and Care: Centering Global South Conceptualizations of Childhood/s.” Review of Research in Education 41 (1): 1–29. https://doi.org/10.3102/0091732X16688621.; Souto-Manning and Rabadi-Raol [2018]. “(Re)Centering Quality in Early Childhood Education: Toward Intersectional Justice for Minoritized Children.” Review of Research in Education 42 (1): 203–225. https://doi.org/10.3102/0091732X187595.), the new edition continues to centre dominant developmental approaches where adults hyperfocus on children’s differences or individual characteristics rather than on changing educational structures and practices that promote inequity (Ferri and Bacon [2011]. “Beyond Inclusion: Disability Studies in Early Childhood Teacher Education.”). The revised guidelines do not go far enough to address inequity and to give teachers and programmes tools for addressing injustice for all young children. This manuscript builds on previous critiques of DAP by explicitly addressing the exclusion of disabled children from the guidelines.

Malignant Abrikossoff’s Tumour of the Tonsil - A Case Report of a Rare Entity

Abstract Rationale: This study aimed to report an uncommon site of origin of a rare head-and-neck cancer, namely malignant granular cell tumour. Patient Concerns: An 89-year-old female patient complained of persistent pharyngodynia and odynophagia for two months. Diagnosis: Upon clinical examination, the right palatine tonsil was larger and palpably firmer than the contralateral. An incisional biopsy of the lesion was performed under local anaesthesia revealing malignant granular cell tumour. A contrast-enhanced computed tomography (CECT) scan of the head and neck and an 18F-fluoro-2-deoxy-D-glucose positron emission tomography (PET) scan confirmed the presence of a pathologic appearance of the right palatine tonsil without nodal or distant metastasis. Treatment: Following a multidisciplinary consultation and the patient’s informed permission, a right tonsillectomy extended to the constrictor muscle fibres of the upper pharynx was performed. Outcomes: The tumour was staged as pT2 R0 cN0 M0, according to the AJCC 8th edition for soft-tissue tumours of the head and neck. Due to the early stage and the radicality of surgery, no further adjuvant treatments were provided. The patient is currently followed up with no evidence of disease one year post-operatively. Take-away Lessons: Granular cell tumours are rare mesenchymal tumours, firstly described by the pathologist Abrikossoff in 1926. This type of tumour constitutes approximately 0.5% of all soft-tissue tumours, and can affect any part of the body, with the head and neck being the most frequently involved site. The tonsil is an extremely rare localisation of this cancer. The differential diagnosis of unilateral tonsillar enlargement should also include this histological entity.

Neuropsychological profile associated with KAT6A syndrome: Emergent genotype-phenotype trends

BackgroundKAT6A (Arboleda-Tham) syndrome is a Mendelian disorder of the epigenetic machinery caused by pathogenic variants in the lysine acetyltransferase 6 A (KAT6A) gene. Intellectual disability and speech/language impairment (e.g., minimally verbal) are common features of the disorder, with late-truncating variants associated with a more severe form of intellectual disability. However, much of the cognitive phenotype remains elusive given the dearth of research.Participants and methodsThis study examined non-verbal and social skills of 15 individuals with molecularly-confirmed diagnoses of KAT6A syndrome (Mean age = 10.32 years, SD = 4.12). Participants completed select subtests from the DAS-II, the NEPSY-II, and the Beery Buktenica Developmental Test of Visual Motor Integration 6th Edition, and their caregivers completed an assortment of behavior rating inventories.ResultsFindings suggest global cognitive impairment with nonverbal cognition scores similar to those for receptive language. Autism-related features, particularly restricted interests and repetitive behaviors, and broad adaptive deficits were common in our sample juxtaposed with a relatively strong social drive and low frequency of internalizing and externalizing behavioral problems. A general trend of lower performance scores on nonverbal and receptive language measures was observed among those with protein-truncating variants vs. missense variants; however, no effect was observed on caregiver rating inventories of daily behaviors. Late and early truncating variants yielded comparable neuropsychological profiles.ConclusionsOverall, study results show the cognitive phenotype of KAT6A syndrome includes equally impaired nonverbal cognition and receptive language functioning, paired with relatively intact social drive and strengths in behavior regulation. Emergent genotype-phenotype correlations suggest cognition may be more affected in protein-truncating than missense mutations although similar neurobehavioral profiles were observed.

Trends in falls among older adults before and during the COVID-19 pandemic in Ontario, Canada: A retrospective observational study

BackgroundThe public health measures associated with the COVID-19 pandemic may have indirectly impacted other health outcomes, such as falls among older adults. The purpose of this study was to examine trends in fall-related hospitalizations and emergency department visits among older adults before and during the COVID-19 pandemic in Ontario, Canada.MethodsWe obtained fall-related hospitalizations (N = 301,945) and emergency department visit (N = 1,150,829) data from the Canadian Institute for Health Information databases from 2015 to 2022 for adults ages 65 and older in Ontario. Fall-related injuries were obtained using International Classification of Diseases, 10th edition, Canada codes. An interrupted time series analysis was used to model the change in weekly fall-related hospitalizations and emergency department visits before (January 6, 2015-March 16, 2020) and during (March 17, 2020-December 26, 2022) the pandemic.ResultsAfter adjusting for seasonality and population changes, an 8% decrease in fall-related hospitalizations [Relative Rate (RR) = 0.92, 95% Confidence Interval (CI): 0.85, 1.00] and a 23% decrease in fall-related emergency department visits (RR = 0.77, 95%CI: 0.59, 1.00) were observed immediately following the onset of the pandemic, followed by increasing trends during the pandemic for both outcomes.ConclusionsFollowing an abrupt decrease in hospitalizations and emergency department visits immediately following the onset of the pandemic, fall-related hospitalizations and emergency department visits have been increasing steadily and are approaching pre-pandemic levels. Further research exploring the factors contributing to these trends may inform future policies for public health emergencies that balance limiting the spread of disease among this population while supporting the physical, psychological, and social needs of this vulnerable group.

Serum AXL is a potential molecular marker for predicting COVID-19 progression.

The severity, symptoms, and outcome of COVID-19 is thought to be closely linked to how the virus enters host cells. This process involves the key roles of angiotensin-converting enzyme 2 (ACE2) and the Tyrosine protein kinase receptor UFO (AXL) receptors. However, there is limited research on the circulating levels of ACE2 and AXL and their implications in COVID-19. A control group of 71 uninfected individuals was also included in the study. According to the Guidance for Corona Virus Disease 2019 (10th edition), a cohort of 358 COVID-19 patients were categorized into non-severe and severe cases. Serum ACE2/AXL levels in COVID-19 patients were detected by enzyme-linked immunosorbent assay (ELISA) at different time points post-COVID-19 infection, including days 0-7, 8-15, 31-179 and >180 days. Serum SARS-CoV-2 IgG/IgM antibodies in COVID-19 patients at the same intervals were assessed by using an iFlash 3000 Chemiluminescence Immunoassay Analyzer. The receiver operating characteristic (ROC) curves were used to assess the diagnostic value of the biological markers, and the association between laboratory parameters and illness progression were explored. Compared with the uninfected group, the levels of ACE2 and AXL in the COVID-19 group were decreased, and the SARS-COV-2 IgG level was increased. AXL (AUC = 0.774) demonstrated a stronger predictive ability for COVID-19 than ACE2. In the first week after infection, only the level of AXL was statistically different between severe group and non-severe group. After first week, the levels of ACE2 and AXL were different in two groups. Moreover, in severe COVID-19 cases, the serum ACE2, AXL, and SARS-COV-2 IgM levels reached a peak during days 8-15 before declining, whereas serum SARS-COV-2 IgG levels continued to rise, reaching a peak at day 31-180 days before decreasing. In addition, the AXL level continued to decrease and the SARS-COV-2 IgG level continued to increase in the infected group after 180 days compared to the uninfected group. The levels of serum ACE2 and AXL correlate with COVID-19 severity. However, AXL can also provide early warning of clinical deterioration in the first week after infection. AXL appears to be a superior potential molecular marker for predicting COVID-19 progression.

Carbon ion radiotherapy for mesonephric adenocarcinoma of the uterine cervix: a case report

BackgroundMesonephric adenocarcinoma is an extremely rare subtype of uterine cervical cancer that is associated with a poor prognosis and for which a standardized treatment protocol has not been established. Carbon ion radiotherapy (CIRT) is an emerging radiotherapy modality that has been shown to have a favorable anti-tumor effect, even for tumors resistant to conventional photon radiotherapy or chemotherapy. However, there is no report on CIRT outcomes for mesonephric adenocarcinoma of the uterine cervix.Case presentationWe treated a 47-year-old Japanese woman with mesonephric adenocarcinoma of the uterine cervix (T2bN0M0 and stage IIB according to the 7th edition of the Union for International Cancer Control and International Federation of Gynecology and Obstetrics, respectively) with CIRT combined with brachytherapy and concurrent chemotherapy. CIRT consisted of whole pelvic irradiation and boost irradiation to the gross tumor; 36.0 Gy (relative biological effectiveness [RBE]) in 12 fractions and 19.2 Gy (RBE) in 4 fractions, respectively, performed once a day, four times per week. Computed tomography-based image-guided adaptive brachytherapy was performed after completion of CIRT, for which the D90 (i.e., the dose prescribed to 90% of the target volume) for the high-risk clinical target volume was 20.4 Gy in a total of 3 sessions in 2 weeks. A weekly cisplatin (40 mg/m2) dose was administered concomitantly with the radiotherapy for a total of five courses. From 4 months post-CIRT, the patient developed metastasis of the lung, with a total of 10 lung metastases over 70 months; these lesions were treated on each occasion by photon stereotactic body radiotherapy and/or systemic therapy. At 8 years from initial treatment (i.e., 2 years after the last treatment), the patient is alive without any evidence of recurrence and maintains a high quality of life.ConclusionsThis is the first report of CIRT for treatment of mesonephric adenocarcinoma of the uterine cervix. The present case indicates the potential efficacy of CIRT in combination with brachytherapy for treatment of this disease.

Application of Patient-Reported Outcome Measurements in Adult Tumor Clinical Trials in China: Cross-Sectional Study.

International health policies and researchers have emphasized the value of evaluating patient-reported outcomes (PROs) in clinical studies. However, the characteristics of PROs in adult tumor clinical trials in China remain insufficiently elucidated. This study aims to assess the application and characteristics of PRO instruments as primary or secondary outcomes in adult randomized clinical trials related to tumors in China. This cross-sectional study identified tumor-focused randomized clinical trials conducted in China between January 1, 2010, and June 30, 2022. The ClinicalTrials.gov database and the Chinese Clinical Trial Registry were selected as the databases. Trials were classified into four groups based on the use of PRO instruments: (1) trials listing PRO instruments as primary outcomes, (2) trials listing PRO instruments as secondary outcomes, (3) trials listing PRO instruments as coprimary outcomes, and (4) trials without any mention of PRO instruments. Pertinent data, including study phase, settings, geographic regions, centers, participant demographics (age and sex), funding sources, intervention types, target diseases, and the names of PRO instruments, were extracted from these trials. The target diseases involved in the trials were grouped according to the American Joint Committee on Cancer Staging Manual, 8th Edition. Among the 6445 trials examined, 2390 (37.08%) incorporated PRO instruments as part of their outcomes. Within this subset, 26.82% (641/2390) listed PRO instruments as primary outcomes, 52.72% (1260/2390) as secondary outcomes, and 20.46% (489/2390) as coprimary outcomes. Among the 2,155,306 participants included in these trials, PRO instruments were used to collect data from 613,648 (28.47%) patients as primary or secondary outcomes and from 74,287 (3.45%) patients as coprimary outcomes. The most common conditions explicitly using specified PRO instruments included thorax tumors (217/1280, 16.95%), breast tumors (176/1280, 13.75%), and lower gastrointestinal tract tumors (173/1280, 13.52%). Frequently used PRO instruments included the European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire-30, the visual analog scale, the numeric rating scale, the Traditional Chinese Medicine Symptom Scale, and the Pittsburgh Sleep Quality Index. Over recent years, the incorporation of PROs has demonstrated an upward trajectory in adult randomized clinical trials on tumors in China. Nonetheless, the infrequent measurement of the patient's voice remains noteworthy. Disease-specific PRO instruments should be more effectively incorporated into various tumor disease categories in clinical trials, and there is room for improvement in the inclusion of PRO instruments as clinical trial end points.

The World Health Organization Reporting System for Pancreaticobiliary Cytopathology: Overview and Summary.

The recently published WHO Reporting System for Pancreaticobiliary Cytopathology (World Health Organization [WHO] System) is an international approach to the standardized reporting of pancreaticobiliary cytopathology, updating the Papanicolaou Society of Cytopathology System for Reporting Pancreaticobiliary Cytology (PSC System). Significant changes were made to the categorization of benign neoplasms, intraductal neoplasms, mucinous cystic neoplasms, and malignant neoplasms considered low grade. Benign neoplasms, such as serous cystadenoma, categorized as Neoplastic: benign in the PSC system, are categorized as Benign/negative for malignancy in the WHO system. Pancreatic neuroendocrine tumor, solid-pseudopapillary neoplasm, and gastrointestinal stromal tumor, categorized as Neoplastic: other in the PSC system, are categorized as Malignant in the WHO System in accord with their classification in the 5th edition WHO Classification of Digestive System Tumours (2019). The two new categories of Pancreaticobiliary Neoplasm Low-risk/grade and Pancreaticobiliary Neoplasm High-risk/grade are mostly limited to intraductal neoplasms and mucinous cystic neoplasms. Low-risk/grade lesions are mucinous cysts, with or without low-grade epithelial atypia. High-risk/grade lesions contain neoplastic epithelium with high-grade epithelial atypia. Correlation with clinical, imaging, and ancillary studies remains a key tenet. The sections for each entity are written to highlight key cytopathological features and cytopathological differential diagnoses with the pathologist working in low resource setting in mind. Each section also includes the most pertinent ancillary studies useful for the differential diagnosis. Sample reports are provided for each category. Finally, the book provides a separate section with risk of malignancy and management recommendations for each category to facilitate decision-making for clinicians.

Challenges in the Assessment of Medullary Bone Invasion in Oral Cavity Cancers and Its Prognostic Significance.

As per AJCC 8th edition TNM staging system, bone invasion is a poor prognostic marker that upstages oral cavity squamous carcinoma (OSCC) to pT4a. Cortical erosion alone of bone or tooth socket by a gingival primary is not sufficient to upstage a tumour. The differentiation of cortical erosion from invasion through the cortical bone into the medulla is often challenging, limiting accurate staging. This review aims to assess the difficulties in differentiating cortical erosion from medullary invasion and evaluate the prognostic significance of different patterns of bone involvement. A retrospective review of OSCC with primary curative surgery and bone resection treated at a single-center over 10years, was performed to assess the prognostic significance of bone invasion. Hematoxylin-eosin stained slides of a subset of cases were re-reviewed in a planned manner to assess difficulties in precise categorization (no invasion/erosion/cortical invasion and medullary invasion), evaluate interobserver agreement, and correlate with clinical outcome. Five hundred and ninety patients were included, with a median follow-up of 28months. On univariate analysis, the 3-year local, nodal and distant metastasis control were not significantly different in the 3 groups of no invasion, erosion, and invasion (p = 0.43, 0.47, and 0.47, respectively). Overall survival (OS) at 3years was 78.1% and disease-free-survival(DFS) was 63.7% in the entire cohort. On univariate analysis, there was significant difference in OS and DFS based on these groups. This did not translate into independent prognostic benefit on multivariable analysis (p = 0.75 and 0.19, respectively). The independent prognostic factors were margin positivity, tumor differentiation, perineural invasion and pathological nodal involvement. Planned re-review of a subset of 202 cases resulted in a change in bone involvement category in 26/202 cases, which was mainly due to difficulty in assessing cortico-medullary junction near the tooth socket and bone fragmentation. The assessment showed moderate to near complete agreement (kappa 0.59-0.82) between 2 observers. Our study shows that bone involvement is not an independent prognostic marker and there is no specific correlation of medullary invasion with outcome over those that showed cortical erosion. Several factors contribute to difficulties and interobserver variability in assessing bone involvement.

The Impact of The Covid-19 Pandemic on The Selected Countries in Sub-Saharan Africa in Terms of GDP, Inflation and Balance of Payment (BPM6)

This study examines the impact of the COVID-19 pandemic on selected Sub-Saharan African countries in terms of GDP, Inflation, and Balance of Payment (BPM6) The paper addresses a significant knowledge gap regarding the pandemic's influence on emerging financial markets in Africa. A longitudinal research design was adopted, analyzing data from Ghana, Kenya, Nigeria, and South Africa between 2017 and 2022. The study utilized GDP per capita growth, Inflation, and Balance of Payment as dependent variables, employing a repeated measure of ANOVA for analysis. The use of the 6th edition of the Balance of Payments Manual (BPM6) is an important macro-economic indicator significant in determining the performance of any country with the rest of the world. The results indicate substantial shifts in BPM6, GDP, and inflation rates before and after the pandemic. Specifically, there was a decrease in BPM6 deficits, an increase in inflation rates, and a slowdown in GDP growth post-pandemic, highlighting COVID-19's significant economic impact. The study recommends implementing policies to stabilize the economy, focusing on fiscal stimuli to boost GDP, controlling inflation, and managing external debts to improve the balance of payments. This research provides valuable insights for policymakers, investors, and stakeholders to effectively navigate financial market dynamics in Africa during and beyond the pandemic era.

Is ChatGPT reliable and accurate in answering pharmacotherapy-related inquiries in both Turkish and English?

IntroductionArtificial intelligence (AI), particularly ChatGPT, is becoming more and more prevalent in the healthcare field for tasks such as disease diagnosis and medical record analysis. The objective of this study is to evaluate the proficiency and accuracy of ChatGPT in different domains of clinical pharmacy cases and queries. MethodsThe study NAPLEX® Review Questions, 4th edition, pertaining to 10 different chronic conditions compared ChatGPT's responses to pharmacotherapy cases and questions obtained from McGraw Hill's, alongside the answers provided by the book's authors. The proportion of correct responses was collected and analyzed using the Statistical Package for the Social Sciences (SPSS) version 29. ResultsWhen tested in English, ChatGPT had substantially higher mean scores than when tested in Turkish. The average accurate score for English and Turkish was 0.41 ± 0.49 and 0.32 ± 0.46, respectively, p = 0.18. Responses to queries beginning with “Which of the following is correct?” are considerably more precise than those beginning with “Mark all the incorrect answers?” 0.66 ± 0.47 as opposed to 0.16 ± 0.36; p = 0.01 in English language and 0.50 ± 0.50 as opposed to 0.14 ± 0.34; p < 0.05in Turkish language. ConclusionChatGPT displayed a moderate level of accuracy while responding to English inquiries, but it displayed a slight level of accuracy when responding to Turkish inquiries, contingent upon the question format. Improving the accuracy of ChatGPT in languages other than English requires the incorporation of several components. The integration of the English version of ChatGPT into clinical practice has the potential to improve the effectiveness, precision, and standard of patient care provision by supplementing personal expertise and professional judgment. However, it is crucial to utilize technology as an adjunct and not a replacement for human decision-making and critical thinking.

Predictive potential of preoperative Naples prognostic score-based nomogram model for the prognosis in surgical resected thoracic esophageal squamous cell carcinoma patients: A retrospective cohort study.

The present study aimed to establish an effective prognostic nomogram model based on the Naples prognostic score (NPS) for resectable thoracic esophageal squamous cell carcinoma (ESCC). A total of 277 patients with ESCC, who underwent standard curative esophagectomy and designated as study cohort, were retrospectively analyzed. The patients were divided into different groups, including NPS 0, NPS 1, NPS 2, and NPS 3 or 4 groups, for further analysis, and the results were validated in an external cohort of 122 ESCC patients, who underwent surgery at another cancer center. In our multivariate analysis of the study cohort showed that the tumor-node-metastasis (TNM) stage, systemic inflammation score, and NPS were the independent prognostic factors for the overall survival (OS) and progression-free survival (PFS) durations. In addition, the differential grade was also an independent prognostic factor for the OS in the patients with ESCC after surgery (all P < .05). The area under the curve of receiver operator characteristics for the PFS and OS prediction with systemic inflammation score and NPS were 0.735 (95% confidence interval [CI] 0.676-0.795, P < .001) and 0.835 (95% CI 0.786-0.884, P < .001), and 0.734 (95% CI 0.675-0.793, P < .001) and 0.851 (95% CI 0.805-0.896, P < .001), respectively. The above independent predictors for OS or PFS were all selected in the nomogram model. The concordance indices (C-indices) of the nomogram models for predicting OS and PFS were 0.718 (95% CI 0.681-0.755) and 0.669 (95% CI 0.633-0.705), respectively, which were higher than that of the 7th edition of American Joint Committee on Cancer TNM staging system [C-index 0.598 (95% CI 0.558-0.638) for OS and 0.586 (95% CI 0.546-0.626) for PFS]. The calibration curves for predicting the 5-year OS or PFS showed a good agreement between the prediction by nomogram and actual observation. In the external validation cohort, the nomogram discrimination for OS was better than that of the 7th edition of TNM staging systems [C-index: 0.697 (95% CI 0.639-0.755) vs 0.644 (95% CI 0.589-0.699)]. The calibration curves showed good consistency in predicting the 5-year survival between the actual observation and nomogram predictions. The decision curve also showed a higher potential of the clinical application of predicting the 5-years OS of the proposed nomogram model as compared to that of the 7th edition of TNM staging systems. The preoperative NPS-based nomogram model had a certain potential role for predicting the prognosis of ESCC patients.

Prevalence of insomnia in a general adult population cohort using different diagnostic criteria: The seventh survey of the Tromsø study 2015–2016

Insomnia disorder is a subjective complaint of sleep dissatisfaction including both night-time and daytime symptoms. Currently there are three commonly used diagnostic manuals each with their own set of criteria, which is often credited for the wide range in insomnia prevalence reported by population-based studies, especially those with self-reported insomnia. However, there are limited studies directly comparing different criteria and little is known about associations with health outcomes. Thus, the aim of this study was to compare the most commonly used diagnostic criteria for insomnia from the literature and to explore the associations with a range of physical and mental health outcomes. We used data from 21,083 women and men from the seventh survey of the population-based Tromsø Study which included adults aged 40–99 years. A revised version of the Bergen Insomnia Scale was used to define insomnia based on the 4th (revised) and 5th edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR and DSM5), the 10th edition of the International Classification of Diseases (ICD-10), and the 3rd edition of the International Classification of Sleep Disorders (ICSD-3). We found the following prevalence of insomnia: DSM-IV-TR 23.6 %, DSM5 8.5 %, ICD-10 9.9 % and ICSD-3 20.0 %. When looking at each symptom, we found over half the participants classified as having insomnia using the DSM-IV-TR and ICSD-3 criteria did not report having impaired daytime functioning at least three days per week. Overall, participants with DSM5 and ICD-10 insomnia appeared to have worse health profiles, based on a higher percentage meeting the cut-off for possible anxiety or depression, reporting a psychological problem or chronic pain, and using antidepressants, painkillers or sleeping pills. However logistic regression models showed largely the same health factors had the same association with the odds for being classified as having insomnia disorder from each set of criteria. Overall, this study suggests that insomnia prevalence may be overestimated if daytime symptoms are not adequately included in accordance with current guidelines.

Abstract PO5-27-01: Comparison between the 7th and the 8th edition of TNM Staging System of American joint committee on Cancer(AJCC) for Breast Cancer Patients, diagnosed and treated at King Abdulaziz Medical City

Abstract Breast cancer is a heterogeneous disease with different biological and molecular characteristics that affect local recurrence, metastases, prognoses, and response to available therapies. The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for breast cancer has incorporated the biological and molecular characteristics, tumor grade, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor status(Her-2)and tumor grade, into the traditional anatomical 7th edition that only considers tumor size, lymph nodes status, and distant metastases. The aim of this study is to compare the 7th to 8th editions of the AJCC staging system for prognostic impact, assess the effect of the new edition on the treatment and treatment outcome Method A retrospective cohort study was performed for all breast cancer patients, diagnosed between (2013 -2019) and underwent upfront surgery at King Abdulaziz Medical City (KAMC).Patients’ clinicopathological, immunohistochemical, surgical, therapeutic, and follow-up data were retrieved. Overall survival (OS) and breast cancer-specific survival (BCSS) were estimated using the Kaplan–Meier method. Univariate analysis using Fisher's exact test was used to compare staging systems' prognostic accuracy. Multivariable analysis using Cox proportional hazards regression analysis was performed to identify factors independently associated with disease outcome Results A total of 169 female patients were included, the 8th AJCC staging system resulted in a reallocation of 108 (63.9%) of the patients to a different stage group. The majority were downstaged(60.9%) while only 3% were upstaged, most of the upstaged patients had a triple-negative subtype (80%). The change in overall stage for the 8th edition was most significant in stage I (an increase by 140.3%), followed by stage II (downstaged by 74.3%) and stage III (downstaged by 49.7%) compared to the 7th edition. Critically 42.8% of all downstaged patients treated with adjuvant chemotherapy were found to have received unnecessary chemotherapy after applying the 8th AJCC staging system as per National Comprehensive Cancer Network (NCCN) clinical practice guidelines recommendations. The 8th AJCC staging system was a better prognostic predictor of disease survival, patients in 8th AJCC stage 3 had a higher tendency to develop metastases and die because of their disease (P-value 0.03, 0.051, respectively). Conclusions: Our comparison revealed that the AJCC 8th edition staging system is superior and more comprehensive than the 7th, in term of prognostic value, and in defining the precise adjuvant therapy Figure 1 Comparison of the 7th AJCC and the 8th AJCC staging system Citation Format: Nafisa Abdelhafiez, Abdulmohsen Alkushi, Lolwah Alriyees, Mohammad Arabi, Faris Alsalamah, Emad Masuadi, Ahmad Omair, Mohammad Alkaiyat, Hussam Shehata.

Abstract PO3-15-08: Validation for prognostic staging based AJCC 8th edition with nuclear grade in Japanese breast cancer patients: A multicenter retrospective study

Abstract Introduction. The American Joint Committee on Cancer (AJCC) 8th edition of breast cancer classification introduced the concept of "prognostic stage," which is based on anatomic classification (TNM classification) plus four biomarkers: estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor (HER2), and histological grading (HG). In Japan, however, the introduction of histological classification has been passive and slow, and the nuclear grading (NG) has been used so far. Objective. Our aim is to compare the prognostic staging classification in the AJCC, 8th edition which substitutes NG for HG (AJCC8th-NG) with the TNM classification, and to confirm the usefulness of AJCC8th-NG classification. Methods. We collected 5229 patients with primary breast cancer operated on between 2005 and 2013 at six institutions affiliated with Kyushu University Hospital in Japan, for whom prognosis was available. We retrospectively evaluated the 7-year survival rates based on the TNM classification and the AJCC8th-NG classification, based on the pathological diagnosis of their surgeries. Results. Median age was 58 years (24-99), 5210 (99.6%) were female, and the 7-year survival rate of all eligible patients was 93.2%. The changes in the number of cases by stage were observed as follows: Stage 0 (16.5%), Stage IA (42.3% to 56.2%), Stage IB (0.3% to 8.8%), Stage IIA (21.5% to 6.9%), Stage IIB (9.7% to 3.1%), Stage IIIA (3.9% to 3.5%), Stage IIIB (1.5% to 1.9%), Stage IIIC (2.1% to 0.9%), Stage IV (1.9%). The changes in 7-year survival rates were observed as follows: Stage 0 (96.1%), Stage IA (96.8% → 96.5%), Stage IB (93.7% → 93.4%), Stage IIA (93.1% → 87.8%), Stage IIB (88.5% → 84.6%), Stage IIIA (86.9% → 80.4%), Stage IIIB (78 .7% to 84.4%), Stage IIIC (79.8% to 58.4%), and Stage IV (51.9%). (TNM classification →AJCC8th-NG classification) Both TNM classification and AJCC8th-NG classification were significantly associated with prognosis. AJCC8th-NG classification was more stratified. In AJCC 8th-NG Stage IB, which is the largest population in all patients, 42% of that were triple-negative type (TN) downstaging from TNM Stage IA and 58% were luminal type downstaging from TNM Stage II-IIIA. In AJCC 8th-NG Stage IIIC, which was changed the most with biomarkers, 52% of that were TN upstaging from TNM Stage IIIA-IIIB. On the other hand, 50% of AJCC 8th-NG Stage IIIB with a favorable prognosis were ER-positive or HER2-positive downstaged from TNM Stage IIIC. Discussion TN breast cancer generally has a poor prognosis. However, HER2-positive breast cancer, which used to have a poor prognosis, is said to have a favorable prognosis after the availability of anti-HER2 drugs. This time, we examined cases after 2005 when anti-HER2 drugs became available in Japan, but the results did not show that HER2-positive breast cancer had a better prognosis than HER2-negative breast cancer. In this study, we were unable to confirm the use of anti-HER2 drugs. In the AJCC 8th classification, it seems necessary to consider whether or not treatment is being provided. If all patients are treated, the prognostic stratification will become clearer. Conclusion. Our study could show that AJCC8th-NG classification was useful for predicting prognosis same as AJCC8th classification in the relatively large cohort.

Abstract PO3-06-02: Ten years axillary recurrence and survival after omission of axillary lymph node dissection in breast cancer patients with micrometastases or isolated tumor cells in the sentinel node: A Danish national register study

Abstract Background: Until 2012, breast cancer patients with micrometastases (pN1mi) or isolated tumor cells (pN0(i)) in the sentinel node (SN) received axillary lymph node dissection (ALND). ALND is associated with lymphedema, paresthesia, functional impairment, and pain. In 2012, national Danish guidelines for patients with pN1mi and pN0(i) were changed reflecting several randomized clinical trials showing non-inferior prognosis when ALND was omitted. Since 2012, appr. 450 Danish breast cancer patients have been spared ALND each year. Development of axillary recurrence(AR) from minimal metastatic disease left in the axilla may take longer than experienced after macrometastatic disease. Hence, long-term follow-up is needed to evaluate the safety of omitting ALND for patients with pN1mi and pN0(i). Therefore, we aimed to investigate these outcomes with 10 years of follow-up. Methods: In this national register-based study, we included all women with primary breast cancer surgery between 01.01.2008 and 31.12.2021, who had pN1mi and pN0(i) in the SN. Women treated between 01.01.2008-31.12.2011 had received ALND, while in women treated between 01.01.2012 and 31.12.202,1 ALND was omitted. The two groups were compared with SN-negative patients (pN0) without ALND. The primary outcome was AR, and the secondary outcome was overall survival (OS). Information on surgery, nodal status, and recurrence were retrieved from the national Danish breast cancer group (DBCG) database. The definitions of pN1mi, pN0(i) and pN0 were according to AJCC, 8TH edition. We analyzed patient- and tumor characteristics with descriptive statistics, χ2 and Fisher exact test. The cumulative incidence of AR was calculated. OS was estimated using the Kaplan-Meier method and compared with a log-rank test. The effect of ALND was estimated with a Cox proportional hazards model, adjusting for age at operation, histology, malignancy grade, hormone receptor, HER2 status, and whether they received adjuvant systemic treatment or radiation therapy. With all statistical analysis, a two-tailed α-level of 0.05 was used. Results: 22,790 patients were included in the study. Overall,14.3% had pN1mi, 8.6% had pN0(i) and 77.1% had pN0. Of pN1mi or pN0(i) patients, 1490 had an ALND; 1227 patients with pN1mi and 263 patients with pN0(i). In 3737 patients ALND was omitted: 2036 with pN1mi and 1701 with pN0(i). Regarding the primary outcome, 1.1% of patients with pN1mi or pN0(i) had an AR, while 0.5% of the pN0 patients had AR. Analyzing patients with pN1mi or pN0(i) with or without ALND, 0.2% and 1.5%, respectively, had an AR. In subanalysis of patients with pN1mi with or without ALND, 0.2% and 1.8%, respectively, had an AR. In a subanalysis of patients with pN0(i), no patients with pN0(i) and ALND had an AR, while 1.1% of patients with pN0(i) had an AR when ALND was omitted. OS after 10 years of follow-up for the group of patients with pN1mi or pN0(i) was 81.5%; 83.7% for patients with and 79.12% for patients without ALND. For pN0 patients without ALND OS was 82%. This difference between the three groups was statistically significant(p&amp;lt; 0,01). However, when adjusting for risk factors, there was no statistically significant difference in OS between the patients with pN1mi or pN0(i) with and without ALND (p=0.6). Likewise, no statistically significant difference was found in OS, when looking at the subgroups of pN1mi with or without ALND (p=0.5) and pN0(i) with and without ALND(p=0.41). Conclusion: In this large register-based nationwide study we found a slightly higher rate of AR after 10 years of follow-up in breast cancer patients with micrometastases or isolated tumor cells in the SN if ALND was omitted. However, the axillary recurrence rate was low (&amp;lt; 2%), and after adjusting for other risk factors the increased recurrence rate did not affect OS. These results confirm the safety of omitting ALND in these patients. Citation Format: Riazan Hawaz-ali, Frederikke Munck, Tove Tvedskov, Niels Kroman.
