Time interval between surgery and adjuvant chemotherapy in patients with gastric cancer after gastrectomy: a population-based cohort study using a nationwide claim database
Authors: Maeng Chi Hoon , Kim Hoseob , Kim Mina 
Published: March 2024

Background: Adjuvant chemotherapy can reduce recurrence rates by eradicating microscopic metastases which may persist after curative resection. However, the optimal time interval (TI) between the surgery and chemotherapy remains controversial. Objectives: This study investigated the optimal TI between surgery and chemotherapy. Design: A population-based cohort study using a nationwide claims database. Methods: The data were obtained from the Korean National Health Insurance Service (NHIS) of Korea. We included patients who underwent gastrectomy between 2013 and 2018. To determine the optimal cutoff point of TI, a restricted cubic spline Cox regression model was established, and categorized the population into three groups based on TI: the early (⩽20 days), the late (⩾35 days), and the reference group (21–34 days), and with the reference group having the lowest mortality and recurrence. Propensity score matching was performed for each group. The primary outcomes were disease-free survival (DFS) and overall survival (OS). Results: After excluding ineligible participants, 6602 patients were included. The median DFS and OS did not differ significantly between the early and reference groups ( p = 0.7258 and p = 0.6056, respectively). In comparison between the late and reference groups, it was significantly lower in the late group ( p = 0.0079). Five-year DFS rates were 77.6% and 81.3% in the late and reference groups, respectively. The late group showed worse OS than the reference group ( p = 0.0336). Five-year OS rates were 82.1% and 85.0% in the late and reference groups, respectively. In the multivariable analysis, DFS in the late group retained inferiority [adjusted hazard ratio (aHR): 1.138, 95% confidence interval (CI): 1.003–1.292, p = 0.045]. OS showed a worse trend without significance compared to the reference group (aHR: 1.138, 95% CI: 0.984–1.317, p = 0.0805). Conclusion: Adjuvant chemotherapy after gastrectomy in patients with gastric cancer should be initiated within 5 weeks of surgery. A delay of more than 5 weeks may have a detrimental effect on the subsequent disease course.

Purpose Diffuse gliomas present a significant challenge for healthcare systems globally. While brain MRI plays a vital role in diagnosis, prognosis, and treatment monitoring, accurately characterizing gliomas using conventional MRI techniques alone is challenging. In this study, we explored the potential of utilizing the amide proton transfer (APT) technique to predict tumor grade and type based on the WHO 2021 Classification of CNS Tumors. Methods Forty-two adult patients with histopathologically confirmed brain gliomas were included in the study. They underwent 3T MRI imaging, which involved APT sequence. Multinomial and binary logistic regression models were employed to classify patients into clinically relevant groups based on MRI findings and demographic variables. Results We found that the best model for tumor grade classification included patient age along with APT values. The highest sensitivity (88%) was observed for Grade 4 tumors, while Grade 3 tumors showed the highest specificity (79%). For tumor type classification, our model incorporated four predictors: APT values, patient’s age, necrosis, and the presence of hemorrhage. The glioblastoma group had the highest sensitivity and specificity (87%), whereas balanced accuracy was the lowest for astrocytomas (0.73). Conclusion The APT technique shows great potential for noninvasive evaluation of diffuse gliomas. The changes in the classification of gliomas as per the WHO 2021 version of the CNS Tumor Classification did not affect its usefulness in predicting tumor grade or type.

Published: March 2024

Background Many clinical trials fail because of poor recruitment and enrollment which can directly impact the success of biomedical and clinical research outcomes. Options to leverage digital technology for improving clinical trial management are expansive, with potential benefits for improving access to clinical trials, encouraging trial diversity and inclusion, and potential cost-savings through enhanced efficiency. Objectives This systematic review has two key aims: (1) identify and describe the digital technologies applied in clinical trial recruitment and enrollment and (2) evaluate evidence of these technologies addressing the recruitment and enrollment of racial and ethnic minority groups. Methods We conducted a cross-disciplinary review of articles from PubMed, IEEE Xplore, and ACM Digital Library, published in English between January 2012 and July 2022, using MeSH terms and keywords for digital health, clinical trials, and recruitment and enrollment. Articles unrelated to technology in the recruitment/enrollment process or those discussing recruitment/enrollment without technology aspects were excluded. Results The review returned 614 results, with 21 articles (four reviews and 17 original research articles) deemed suitable for inclusion after screening and full-text review. To address the first objective, various digital technologies were identified and characterized, which included articles with more than one technology subcategory including (a) multimedia presentations (19%, n = 4); (b) mobile applications (14%, n = 3); (c) social media platforms (29%, n = 6); (d) machine learning and computer algorithms (19%, n = 4); (e) e-consenting (24%, n = 5); (f) blockchain (5%, n = 1); (g) web-based programs (24%, n = 5); and (h) virtual messaging (24%, n = 5). Additionally, subthemes, including specific diseases or conditions addressed, privacy and regulatory concerns, cost/benefit analyses, and ethnic and minority recruitment considerations, were identified and discussed. Limited research was found to support a particular technology's effectiveness in racial and ethnic minority recruitment and enrollment. Conclusion Results from this review illustrate that several types of technology are currently being explored and utilized in clinical trial recruitment and enrollment stages. However, evidence supporting the use of digital technologies is varied and requires further research and evaluation to identify the most valuable opportunities for encouraging diversity in clinical trial recruitment and enrollment practices.
Real-world effectiveness of add-on fremanezumab in patients receiving onabotulinumtoxinA for the prevention of chronic migraine in a US tertiary headache center: A retrospective chart review study
Authors: Yuan Hsiangkuo , Cohen Fred , Driessen Maurice T , Krasenbaum Lynda J , Ortega Mario , Hopkins Mary , Marmura Michael J 
Published: March 2024

Background: Concomitant fremanezumab, a calcitonin gene-related peptide (CGRP) pathway monoclonal antibody (mAb), and onabotulinumtoxinA (onabotA) improve treatment response compared with onabotA alone in patients with chronic migraine (CM). Methods: This was a single-center, retrospective, observational study that assessed treatment response (change over time in monthly headache days [MHD] and pain intensity [PI]) in adult patients with CM receiving fremanezumab as add-on therapy to onabotA for CM prevention. Results: In the study population ( N = 116, age 50.0 ± 13.1, female 85.3%, pre-index onabotA use 46.5 ± 34.2 months) receiving concurrent onabotA and fremanezumab for 17.5 ± 11.6 months, MHD decreased by 3.60 days (95% confidence interval [CI]: −5.26, −1.94, p < 0.001) and PI was reduced by 0.43 (95% CI: −0.77, −0.09, p = 0.012) at the final visit. Statistically significant reductions were seen in both MHD (−4.61, 95% CI: −6.84, −2.39; p < 0.001) and PI (−0.52, 95% CI: −0.84. −0.09; p = 0.017) among patients naïve to mAbs against CGRP or its receptor. No unexpected adverse events were observed. Conclusion: Concomitant fremanezumab and onabotA for CM prevention were effective at reducing the number of MHD and lessening PI, particularly in patients with difficult-to-treat CM who are naïve to mAbs against CGRP or its receptor.
Exploring STI/HIV Knowledge and Effect of Communication Activities Among Rohingya Refugee Women: A Camp-based Cross-sectional Study in Bangladesh
Authors: Zakaria Muhammad 
Published: March 2024

Background:HIV is often perceived by many Rohingya individuals as a common ailment, similar to a cough or fever. Given the biological vulnerability of Rohingya women, increasing awareness programs within this population becomes crucial. Therefore, it is important to assess the current knowledge status of STIs/HIV among Rohingya individuals.Objectives:This study aimed to evaluate the knowledge of STIs/HIV and explore the impact of media usage and communication activities among Rohingya refugee women residing in Cox’s Bazar, Bangladesh camps.Methods:A quantitative research approach was employed, utilizing a camp-based cross-sectional sample survey with a structured and facilitator-administered questionnaire. The study involved 415 refugee women as respondents. Hierarchical regression analysis was conducted to identify factors influencing STI/HIV knowledge.Results:The findings revealed that approximately two-thirds of Rohingya refugee women lacked accurate knowledge regarding STI/HIV-related myths and misconceptions. Regression analyses indicated that being a professional ( β = 0.14; p = .003), engaging in discussions about STI/HIV with healthcare workers ( β = 0.25, p < .001), visiting clinics or health facilities ( β = 0.18, p < .001), and observing banners/posters on STI/HIV ( β = 0.20, p < .001) were associated with better STI/HIV knowledge among refugee women. The utilization of communication activities by Rohingya women emerged as a stronger predictor of STI/HIV knowledge compared to socio-demographic factors and media usage-related variables.Conclusions:The study findings can inform the development of appropriate communication programs, campaigns, and effective communication materials aimed at preventing STIs within this vulnerable community.

Background: Community correctional experiences among individuals receiving methadone treatment (MT) for opioid use disorder (OUD) are poorly understood. We qualitatively investigated perceptions of community corrections and treatment experiences among individuals with criminal-legal system experience currently receiving outpatient MT. Methods: From January to December 2017, we recruited 42 individuals with history of criminal-legal system involvement enrolled in outpatient MT at a low-barrier nonprofit organization operating multiple clinics in Connecticut. An experienced qualitative research team conducted one-to-one, in-person, semistructured interviews about incarceration and treatment experiences with individuals receiving MT. Participants completed a demographics survey. The interviews were audiorecorded, transcribed, de-identified, and independently coded using NVivo. Results: Participants described the community corrections system as restrictive and abstinence-focused. Most participants described positive perceptions of and experiences with community corrections officers (CCOs), yet described negative perceptions of and experiences with the community corrections system overall. Participants perceived CCOs to have limited knowledge of OUD and MT. Participants described a range of CCO judgment toward their OUD, with some appearing understanding and nonjudgmental while others were perceived to have stigma and prejudice. Few participants noted assistance from CCOs with seeking MT or community-based substance use disorder care. Some participants desired improved treatment facilitation, but viewed forced or coercive treatment negatively. Conclusion: To our knowledge, this is the first qualitative study to examine community corrections experience among people receiving outpatient medication for OUD. While individuals receiving MT have negative experiences with the community corrections system, they perceive individual CCOs positively. Interventions addressing gaps in CCOs knowledge of OUD and MT are needed to optimize support for individuals on probation or parole with OUD. Provision of OUD treatment facilitation appears desirable to some individuals in community supervision.

Published: March 2024

Abstract
Background
Emerging data suggested a favorable outcome in advanced non-small cell lung cancer (NSCLC) with chronic obstructive pulmonary disease (COPD) patients treated by immunotherapy. The objective of this study was to investigate the effectiveness of neoadjuvant immunotherapy among NSCLC with COPD versus NSCLC without COPD and explore the potential mechanistic links.

Patients and methods
Patients with NSCLC receiving neoadjuvant immunotherapy and surgery at Shanghai Pulmonary Hospital between November 2020 and January 2023 were reviewed. The assessment of neoadjuvant immunotherapy’s effectiveness was conducted based on the major pathologic response (MPR). The gene expression profile was investigated by RNA sequencing data. Immune cell proportions were examined using flow cytometry. The association between gene expression, immune cells, and pathologic response was validated by immunohistochemistry and single-cell data.

Results
A total of 230 NSCLC patients who received neoadjuvant immunotherapy were analyzed, including 60 (26.1%) with COPD. Multivariate logistic regression demonstrated that COPD was a predictor for MPR after neoadjuvant immunotherapy [odds ratio (OR), 2.490; 95% confidence interval (CI), 1.295–4.912; P = 0.007]. NSCLC with COPD showed a down-regulation of HERV–H LTR-associating protein 2 (HHLA2), which was an immune checkpoint molecule, and the HHLA2low group demonstrated the enrichment of CD8+CD103+ tissue-resident memory T cells (TRM) compared to the HHLA2high group (11.9% vs. 4.2%, P = 0.013). Single-cell analysis revealed TRM enrichment in the MPR group. Similarly, NSCLC with COPD exhibited a higher proportion of CD8+CD103+TRM compared to NSCLC without COPD (11.9% vs. 4.6%, P = 0.040).

Conclusions
The study identified NSCLC with COPD as a favorable lung cancer type for neoadjuvant immunotherapy, offering a new perspective on the multimodality treatment of this patient population. Down-regulated HHLA2 in NSCLC with COPD might improve the MPR rate to neoadjuvant immunotherapy owing to the enrichment of CD8+CD103+TRM.

Trial registration
Approval for the collection and utilization of clinical samples was granted by the Ethics Committee of Shanghai Pulmonary Hospital (Approval number: K23-228).
Effects of physical and psychological symptoms on cancer-related fatigue among esophageal cancer patients
Authors: Cui ChunYing , Wang Lie , Wang XiaoXi 
Published: March 2024

Abstract
Background
Cancer-related fatigue (CRF) is considered one of the most prevalent and distressing symptoms among cancer patients and may vary among patients with different cancer types. However, few studies have explored the influence of physical and psychological symptoms on CRF among esophageal cancer (EC) patients without esophagectomy. Therefore, this study aimed to examine the effects of physical and psychological symptoms on CRF among EC patients without esophagectomy.

Methods
In the present study, a cross-sectional study was conducted from February 2021 to March 2022 in Liaoning Province, China. Among the 112 included participants, 97 completed our investigation. The questionnaires used consisted of the Brief Fatigue Inventory (BFI), the MD Anderson Symptom Inventory Gastrointestinal Cancer Module (MDASI-GI), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), and demographic and clinical information. Multivariate linear regression was conducted to test the relationships between physical and psychological symptoms and CRF.

Results
Of the 97 EC patients, 60.8% reported CRF (BFI ≥ 4). The mean age of the participants was 64.92 years (SD = 8.67). According to the regression model, all the variables explained 74.5% of the variance in CRF. Regression analysis indicated that physical symptoms, including constipation, diarrhoea, and difficulty swallowing, contributed to CRF. On the other hand, depressive symptoms increased the level of CRF among EC patients without esophagectomy.

Conclusions
Given the high prevalence of CRF among EC patients without esophagectomy, it is urgent to emphasize the importance of fatigue management interventions based on physical and psychological symptoms to alleviate CRF in EC patients.
Enhancing knowledge mastery in resident students through peer-teaching: a study in respiratory medicine
Authors: Zhu Chen , Tian Heshen , Yan Fugui , Xue Jing , Li Wen 
Published: March 2024

Abstract
Aim
The transition from medical students to competent physicians requires comprehensive training during residency programs. In China, resident students typically undergo 2- or 3-year training programs. While they learn from patient interactions under the guidance of experienced doctors, integrating theoretical knowledge from textbooks into practical cases remains a challenge. This study aimed to explore the impact of medical interns acting as peer-students on the knowledge mastery of resident students.

Method
The participants of this study consisted of resident students specializing in respiratory medicine at the Second Affiliated Hospital of Zhejiang University, School of Medicine. Resident students were given the opportunity to volunteer as peer-teachers for medical interns in the respiratory department. Those who chose to instruct interns were automatically placed into the test group, while those who opted not to partake in intern instruction formed the control group. In their role as peer-teachers, resident students assumed the responsibility of guiding interns in patient management throughout the entire continuum, spanning from initial engagement to discharge, a commitment that extended over a minimum period of 2 weeks. The resident students' academic performance was evaluated through a departmental examination consisting of 50 multiple-choice questions, which was administered upon completing their rotation. Statistical analysis was performed to assess the impact of peer-teaching on the resident students’ performance.

Results
Between January 2023 and June 2023, a total of 158 resident students completed their rotation in the respiratory department. Among them, 40 resident students willingly took on the responsibility of instructing medical interns, while 118 resident students did not participate in intern teaching. With a "one-to-one" teaching policy in place, the overall satisfaction rate of the interns was an impressive 95.35%. Pre-rotation test scores for the test group averaged 81.66 ± 8.325 (Mean ± SD) and the control group averaged 81.66 ± 8.002, without significance. The departmental examination scores of the test group averaged 85.60 ± 7.886, while the control group scored an average of 82.25 ± 8.292, with a statistically significant difference (p = 0.027).

Conclusion
In conclusion, our study underscores the positive influence of peer-teaching on the knowledge mastery of resident students.

Published: March 2024

AbstractBackgroundEnsuring the transition towards person-centred care is a growing focus in health and social care systems globally. Presented as an ethical framework for health and social care professionals, such a transition requires strong leadership and organisational changes. However, there is limited guidance available on how to assist health and social care leaders in promoting person-centred practices. In response to this, the Swedish Association of Health Professionals and the University of Gothenburg Centre for Person-Centred Care collaborated to develop an educational programme on person-centred leadership targeting health and social care leaders to support the transition towards person-centred care in Sweden. The aim with this study was to explore programme management members’ experiences from the development and realisation of the programme.MethodsFocus group discussions were conducted, involving 12 members of the programme management team. Data from the discussions were analysed using a structured approach with emphasis the collaborative generation of knowledge through participant interaction.ResultsThe analysis visualises the preparations and actions involved in programme development and realisation as a collaborative endeavour, aimed at integrating leadership and person-centred ethics in a joint learning process. Participants described the programme as an ongoing exploration, extending beyond its formal duration. Leadership was thoughtfully interwoven with person-centred ethics throughout the programme, encompassing both the pedagogical approach and programme curriculum, to provide leaders with tangible tools for their daily use.ConclusionsAccording to our analysis, we conclude that a person-centred approach to both development and realisation of educational initiatives to support person-centred leadership is essential for programme enhancement and daily implementation of person-centred leadership. Our main message is that educational initiatives on the application of person-centred ethics is an ongoing and collaborative process, characterised by an exchange of ideas and collective efforts.
