RESUMO
Objectives. To identify appropriate interventions to prevent injury, we conducted a qualitative study among commercial shrimp fishermen in the Gulf of Mexico. Methods. Using qualitative and participatory research methods, including interviews, photovoice, and workplace observations in southeast Texas and the Rio Grande Valley in Texas, we examined the socialâstructural dimensions that contribute to physical and psychological injury. Results. We found that multiple layers of vulnerability and danger exist among shrimpers with interacting themes: (1) recognizing risk, (2) precarious employment, and (3) psychological distress. Conclusions. Our results add to the growing body of knowledge that emphasizes the negative health impacts of underregulated, high-risk, and physically demanding work performed primarily by im/migrants. Public Health Implications. Our findings highlight the larger socialâstructural conditions and context of hardships endemic to migrant labor and suggest implications for practice and policy interventions.

OBJECTIVES: This study aimed to determine (1) the needsof Vietnamese people with epilepsy (PWE) and their caregivers for self-management mobile health applications and (2) the self-management features expected to be included in an application. METHODS: The survey consisted of an anonymous self-administered questionnaire that was distributed to PWE and caregivers from the age of 18 in Vietnam through online platforms and onsite at Nguyen Tri Phuong Hospital and University Medical Center, Ho Chi Minh City, from February 2022 to May 2022. The questionnaire assessed the participants' attitudes toward epilepsy self-management mobile applications, their willingness to use applications, and their expectations of the contents of an application. RESULTS: Responses from 103 participants were submitted. Eighty-one participants (78.6%) reported using a smartphone, but only 50.6% of those claimed to know about self-management applications. Most respondents (70.9%) thought the applications would be useful for disease self-management, and 68.9% were willing to use epilepsy self-management applications. In addition, the most expected features to be included in self-management applications were epilepsy information, seizure first aid, connecting with medical professionals, and a seizure diary. CONCLUSION: Most Vietnamese PWE and caregivers had a willingness to use epilepsy self-management applications.The expected features are related to all aspects of self-management, including information, seizure, medication, and safety management.

BACKGROUND: Many adverse events are identified as nursing-sensitive indicators (NSIs) and have evidence-based care bundles known to reduce risk of occurrence. Kamishibai cards are a tool from the manufacturing industry used for practice auditing and improvements. Use of Kamishibai cards is believed to be common in the healthcare setting, but true evidence-based guidelines do not yet exist to guide their implementation. AIMS: The aim of this integrative review was to identify best practices around the implementation of Kamishibai cards in the healthcare setting for improvement in NSI-associated outcomes. METHODS: Eleven nurses at three facilities worked through the evidence using the Johns Hopkins Evidence-Based Practice Model. RESULTS: Ten articles were included for this review. Broad themes included direct observation with non-punitive and timely feedback, clearly visualized results, use of evidence-based care bundles, pre-implementation education, and both leadership and frontline-staff involvement. All facilities showed improvement in NSI-associated outcomes after the implementation of K-cards. LINKING ACTION TO ACTION: In health care, K-cards can be implemented and designed with additional focus on the bundles of care they are intended to audit and staff support, but further evidence would better define guidelines around implementation.

Antibodies to Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) have been reported in pooled healthy donor plasma and intravenous immunoglobulin products (IVIG). It is not known whether administration of IVIG increases circulating anti-SARS-CoV-2 antibodies (COVID ab) in IVIG recipients. COVID ab against the receptor binding domain of the spike protein were analyzed using a chemiluminescent microparticle immunoassay in patients with idiopathic inflammatory myopathies (IIM) both receiving and not receiving IVIG (IVIG and non-IVIG group, respectively). No significant differences in COVID ab levels were noted between IVIG and non-IVIG groups (417 [67-1342] AU/mL in IVIG vs 5086 [43-40,442] AU/mL in non-IVIG, p = 0.11). In linear regression models including all post-vaccination patient samples, higher number of vaccine doses was strongly associated with higher COVID ab levels (2.85 [1.21, 4.48] log AU/mL, regression coefficient [Formula: see text] [95% CI], p = 0.001), while use of RTX was associated with lower ab levels (2.73 [- 4.53, - 0.93] log AU/mL, [Formula: see text][95%CI], p = 0.004). In the IVIG group, higher total monthly doses of IVIG were associated with slightly higher COVID ab levels (0.02 [0.002-0.05] log AU/mL, p = 0.04). While patients on IVIG did not have higher COVID ab levels compared to the non-IVIG group, higher monthly doses of IVIG were associated with higher circulating levels of COVID ab in patients receiving IVIG, particularly in patients concomitantly receiving RTX. Our findings suggest that IIM patients, especially those at increased risk of COVID infection and worse COVID outcomes due to RTX therapy may have protective benefits when on concurrent IVIG treatment.

PURPOSE: This study investigated anorectal manometry (AM) findings and bowel function of patients operated on for Hirschsprung's disease (HD). METHODS: A cross-sectional study was conducted at Children's Hospital 2. Patients operated on for HD from January 2015 to January 2020 were reviewed. Their clinical characteristics, bowel function, and manometric findings were investigated and compared with the references. RESULTS: Ninety-five patients and 95 references were enrolled. Mean ages were 6.6 ± 2.2 years and 7.2 ± 2.9 years,; fecal incontinence rates were 25.3% and 2.1%, and constipation rates were 12.6% and 4.2 for the patients versus the references, respectively. Anal resting pressures were significantly decreased in the patients compared to the references (53.2 ± 16.1 mmHg versus 62.2 ± 14.0 mmHg; p < 0.05). Among the patients, the anal resting pressure was significantly decreased in the incontinents than in the continents (46.0 ± 10.6 mmHg versus 55.6 ± 16.9 mmHg, p < 0.05). During the sensation test, the value of maximum tolerated volume was significantly decreased in the incontinents than in the continents (135.9 ± 47.9 mL versus 166.6 ± 58.3 mL, p < 0.05). CONCLUSION: AM is an objective method providing beneficial information that could guide a more adapted management in HD patients with defecation disorders.

We present a case of complete deficiency of the interferon alpha/beta receptor alpha chain (IFNAR1) in a child with fatal systemic hyperinflammation, apparently provoked by live-attenuated viral vaccination. Such pathologic hyperinflammation, fulfilling criteria for hemophagocytic lymphohistiocytosis, is an emerging phenotype accompanying inborn errors of type I interferon immunity.

The rise of antimicrobial resistance to antibiotics (AMR) as a healthcare crisis has led to a tremendous social and economic impact, whose damage poses a significant threat to future generations. Current treatments either are less effective or result in further acquired resistance. At the same time, several new antimicrobial discovery approaches are expensive, slow, and relatively poorly equipped for translation into the clinical world. Therefore, the use of nanomaterials is presented as a suitable solution. In particular, this review discusses selenium nanoparticles (SeNPs) as one of the most promising therapeutic agents based in the nanoscale to treat infections effectively. This work summarizes the latest advances in the synthesis of SeNPs and their progress as antimicrobial agents using traditional and biogenic approaches. While physiochemical methods produce consistent nanostructures, along with shortened processing procedures and potential for functionalization of designs, green or biogenic synthesis represents a quick, inexpensive, efficient, and eco-friendly approach with more promise for tunability and versatility. In the end, the clinical translation of SeNPs faces various obstacles, including uncertain in vivo safety profiles and mechanisms of action and unclear regulatory frameworks. Nonetheless, the promise possessed by these metalloid nanostructures, along with other nanoparticles in treating bacterial infections and slowing down the AMR crisis, are worth exploring.

(1) Background: Immune cell therapy recently attracted enormous attention among scientists as a cancer treatment, but, so far, it has been poorly studied and applied in Vietnam. The aim of this study was to assess the safety of autologous immune cell therapy for treating lung, liver, and colon cancers-three prevalent cancers in Vietnam. (2) Method: This was an open-label, single-group clinical trial that included 10 patients with confirmed diagnosis of colon, liver, or lung cancer, conducted between March 2016 and December 2017. (3) Results: After 20-21 days of culture, the average number of cytotoxic T lymphocytes (CTLs) increased 488.5-fold and the average cell viability was 96.3%. The average number of natural killer cells (NKs) increased 542.5-fold, with an average viability of 95%. Most patients exhibited improved quality of life, with the majority of patients presenting a score of 1 to 2 in the Eastern Cooperative Oncology Group (ECOG) performance status (ECOG/PS) scale, a decrease in symptoms on fatigue scales, and an increase in the mean survival time to 18.7 months at the end of the study. (4) Conclusion: This method of immune cell expansion met the requirements for clinical applications in cancer treatment and demonstrated the safety of this therapy for the cancer patients in Vietnam.

OBJECTIVE: Measles is still common in many developing countries, and its outbreaks have been on the rise since 2009 even though the disease is almost entirely preventable through safe and effective vaccination. This paper aims to provide evidence about the systematic review of the cost-effectiveness of measles treatment in different regions worldwide. METHODS: The methodical search began on 10th January 2019 to look for all articles on the cost-effectiveness of measles treatment published from January 2019 to April 2019 in SCOPUS, Pubmed (www.ncbi.nlm.nih.gov) and Cochrane (www.cochrane.org).We summarised the articles by using a data table to extract all information using health economic evaluation methods. RESULTS: We identified 14 articles from the 69 total articles searched. These articles showed favourable costeffectiveness or cost-benefit ratios in high- and middle-income countries based on data organised by World Bank Income Level in 2018: the United States, Canada, Japan, India and Zambia. However, research is still limited in lowincome countries and thus the effectiveness of vaccination programmes cannot be conclusively identified. CONCLUSIONS: This review shows the overview of the research in health economic evaluations of measles in different places, years and using different methods of intervention. Overall, it evaluates the cost-effectiveness of measles treatment.

BACKGROUND: Higher body mass index (BMI) has been associated with increased distant recurrence and decreased survival for women with breast cancer. However, the relationship between BMI and locoregional recurrence (LRR) has been less well studied and was therefore the subject of this investigation. METHODS: The study identified 878 women with early-stage invasive breast cancer who underwent breast-conservation therapy (BCT) between June 1997 and October 2007. Time from diagnosis to LRR was calculated using a competing risk analysis with contralateral breast cancer (CBC), distant metastases (DM), and death as the competing risks. Gray's competing risks analysis, which included an interaction term between menopausal status and BMI, was used to identify significant risk factors for the development of LRR. RESULTS: After a median follow-up period of 10.8 years, LRR was diagnosed as a first event for 45 women. In a multivariable analysis, BMI was positively associated with LRR but only in premenopausal women. Specifically, when these women were compared with normal- and underweight women, both the overweight women (hazard ratio (HR), 2.97; 95 % confidence interval (CI) 1.04-8.46; p = 0.04) and the obese women (HR, 3.36; 95 % CI 1.07-10.63; p = 0.04) showed a higher risk of LRR. A similar association between BMI and disease-free survival was noted for premenopausal but not postmenopausal women. CONCLUSION: For premenopausal women with invasive breast cancer who undergo BCT, BMI is an independent prognostic factor for LRR. If confirmed, these findings suggest that more aggressive treatment strategies may be warranted for these women.

Operating since 1994, the UCSD Moores Cancer Center's Asian Grocery Store-Based Cancer Education Program (the Program) is a proven and sustainable strategy for disseminating cancer and poison control information to Asian and Pacific Islander (API) communities. This paper describes the process taken to identify health topics that can be readily addressed within the Program's infrastructure and reports results of the pilot testing of the educational module that was developed by following that process. The development of each new module is guided by the Health Belief Model and the Tipping Point Model. The process starts with the selection of a health topic demonstrating pressing need and treatment options in the API community. Then, using the Pareto principle, reasonably modifiable risk factors are chosen to be addressed in the module. "Sticky messaging" for the modifiable risk factors is developed to package the health information as memorable and transmissible calls-to-action. Finally, grocery store outreaches were used to pilot test the new module to assess its effectiveness at facilitating health care information to API community members. By adhering to the steps described in this paper, the authors were able to: (1) select liver cancer as a pressing API health issue that could be positively impacted by the Program; (2) identify reasonably modifiable risk factors for the chosen health issue; (3) generate compelling call-to-action messages to decrease risk of exposure; and (4) demonstrate the cultural and linguistic alignment of the liver cancer control module. The development and testing of new health education modules follow a methodical process guided by scientific principles. Understanding and employing the elements of an existing evidence-based and sustainable health education program can increase the likelihood of success in addressing the health needs of the API community.

Invasive lobular carcinoma (ILC) typically presents at a later stage than invasive ductal carcinoma (IDC) and poses unique radiographic and surgical challenges. However, current principles of breast-conserving therapy (BCT) do not distinguish between histologic subtypes, raising uncertainty about the optimal approach for patients with ILC. We studied 998 BCT patients from 1998-2007, comprised 74 % IDC, 8 % ILC, and 18 % with mixed ILC/IDC. In light of recent guidelines addressing surgical margins, specimens were assessed for margin width and biologic subtype. The Kaplan-Meier method and Cox proportional hazards models were used to analyze effects of patient and disease characteristics on local recurrence (LR). At a median of 119 months, 45 patients had an isolated LR. 10-year LR was 5.5 % for patients with IDC, 4.4 % for ILC, and 1.2 % for mixed histology (p = 0.08). The majority of ILC cases had luminal A biologic subtype (91.1 %), and analysis among all luminal A cases revealed 10-year LR of 2.6 % for IDC, 3.4 % for ILC, and 0 % for mixed tumors (p = 0.12). Patients with ILC were more likely to have initially positive surgical margins (45.0 vs 17.5 %; p < 0.001) resulting in more frequent re-excision (57.1 % vs 40.4 %; p = 0.02), though final margins were similar between ILC and IDC (p = 0.88). No LR was observed among ILC or mixed histology patients with margins <2 mm (n = 28). On multivariate analysis, histologic subtype was not associated with LR (p = 0.52). Modern approaches confer similarly favorable LR rates for ILC, IDC, and mixed histology breast cancers despite inherent histologic differences. Patients with ILC did not require more extensive surgical margins than those with IDC.

Local-regional recurrence (LRR) after breast-conserving therapy (BCT) can result in distant metastasis and decreased disease-free survival (DFS). This study examines factors associated with DFS following LRR. The initial population included 2,233 consecutive women who underwent BCT from 1998 to 2007. Biologic subtype was approximated using a combination of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and tumor grade. Cumulative incidence of DFS after LRR was calculated. The association of clinical, pathologic, and treatment parameters with DFS was evaluated using a Cox regression model. At a median follow-up of 105 months, 82 patients (3.7%) had a LRR. Of these, 66 (80%) were in-breast and 16 (20%) involved the ipsilateral lymph nodes. Twenty patients subsequently developed distant metastases. Five-year DFS after initial recurrence was 69.6% for the overall cohort. On univariate analysis, triple-negative disease (ER/PR/HER2 negative, TNBC) was associated with reduced DFS (HR = 3.8; 95% CI: 1.8-8.1; p < 0.001). Other factors associated with reduced DFS were larger tumor size (HR = 1.3; 95% CI: 1.03-1.6; p = 0.02), shorter interval from initial diagnosis to LRR (HR = 0.98 per month; 95% CI: 0.97-0.99; p = 0.02), and no salvage surgery (HR = 0.2; 95% CI: 0.09-0.5; p = 0.001). On multivariate analysis, TNBC remained the most significant factor associated with reduced DFS (HR = 4.8; 95% CI: 2.25-10.4; p < 0.001). Compared to women with luminal A disease, those with TNBC had significantly worse DFS (37.5% versus 88.3% at 5 years; p < 0.001). Women with TNBC who developed LRR were at high risk of subsequent recurrence. Efforts should be targeted toward both preventing initial recurrence and decreasing subsequent metastasis.

OBJECTIVES: The perception of oncologists could impact the attractiveness of the specialty and dialogue between oncologists and other physicians. The aim of the study was to describe and understand the stereotypes and social representation (SR) associated with oncologists among medical students, residents and physicians in France. METHODS: This nationwide web-based survey conducted in 2021 was based on hierarchical evocation methods. Qualitative analyses were based on the Reinert method with factorial analyses. Each respondent's SR was graded from 1 to 5 (from 1: very positive SR to 5: very negative SR). RESULTS: Oncologists suffer from a rather negative SR. The negative representation was mostly related to difficulties in practising and the proximity with death and end of life. Oncologists were also associated with more positive notions like interdisciplinarity or intellectual complexity. Attendance to an oncology course was associated with a better SR of oncology (p=0.036), whereas having someone in the family practising oncology had a negative impact (p=0.028). CONCLUSIONS: SR of oncologists is rather contrasted. It was positively influenced by attendance to an oncology course, which could be an option to correct stereotypes and update on this rapidly evolving specialty.

INTRODUCTION: The choice of medical specialization is influenced by various factors, including personal, educational, and interpersonal aspects. However, stereotypes and social representations (SRs) can also play a significant role in biasing the choice of a particular medical specialty. The aim of this study is to describe and understand the social representation (SR) of French Neurologist among medical peers, and factors explaining stereotypes about neurology. METHODS: A nationwide web-based survey was sent to the French medical community (students, residents, and graduated physicians) to collect sociodemographic and professional data, status, experience, and acquaintance in Neurology as well as qualitative hierarchical evocation question to assess the SR of French Neurologists. RESULTS: Overall, 367 people participated in the survey, including 112 medical students, 170 residents, and 85 graduated physicians. Only 14.3% of students listed neurology among their top 5 specialty choices, and 63.8% disagreed with the statement "I could have chosen (or I will choose) neurology after the validation of my 6th year of medical studies." Qualitative analysis revealed that the most frequently occurring words used to describe neurologists were "stroke", "complicated", "no treatment," "clinical", and "brain" and five themes corresponded to SRs of neurologist: his/her personal and professional traits (36.4% of the corpus), his/her daily practice (18.1%), the negative aspects of the neurological practice (15.3%), and the neurological pathology and daily skills (30.2%). CONCLUSION: The perception of neurologists by other physicians is nuanced. Neurologists are described as rigorous specialists, maybe excessively so but the cliché of a contemplative specialty with no effective treatment remains. The specialty and neurological patients suffer also from a reputation of complexity. Further interventions among medical students and better information are required to increase the attractiveness of our specialty.

Genetic medicine, including ribonucleic acid (RNA) therapy, has delivered numerous progresses to the treatment of diseases thanks to the development of lipid nanoparticles (LNPs) as a delivery vehicle. However, RNA therapeutics are still limited by the lack of safe, precise, and efficient delivery outside of the liver. Thus, to fully realize the potential of genetic medicine, strategies to arm LNPs with extrahepatic targeting capabilities are urgently needed. This review explores the current state of next-generation LNPs that can bring RNA biomolecules to their targeted organ. The main approaches commonly used are described, including the modulation of internal lipid chemistries, the use of conjugated targeting moieties, and the designs of clinical administration. This work will demonstrate the advances in each approach and the remaining challenges in the field, focusing on clinical translation.

The CDC crossmatch test is being phased out in solid organ donor allocation, and standard luminex single antigen bead assays do not differentiate complement activating function of HLA antibodies. The current study investigated the LIFECODES C3d-binding assay to determine if it could accurately predict actual T and B cell CDC results in a cohort of highly sensitised patients. Nineteen serum samples from different highly sensitised solid organ patients were crossmatched against cells from 62 unique donors, with 174 total T and B cell crossmatches performed. The sera also underwent SAB assay using OLI and LC platforms, and C3d-binding assay. Complement activating ability of each unique HLA antibody specificity detected using SAB was assigned based on the actual CDC results, which was then used to determine the accuracy of the C3d-binding assay. The C3d-binding assay was found to be highly accurate, with sensitivity of 95%, specificity 89% and negative predictive value 97% for class I DSA and the T cell CDC crossmatch results. Furthermore, we found 100% accuracy for prediction of the complement activating function of HLA-C antibodies. Negative predictive value of above 90% was also found for HLA class II DSA. C3d-binding proved more accurate than virtual crossmatch alone to predict CDC results. This study confirms that the C3d-binding assay predicts actual CDC crossmatch results accurately. In particular, the high negative predictive value of the C3d-binding assay may be extremely useful to define HLA antibodies that do not activate complement in highly sensitised recipients.

OBJECTIVES: This study evaluated the social representation and stereotypes on infectious disease (ID) specialists among medical students and physicians in France after the COVID-19 pandemic. METHODS: A survey applying the hierarchical evocation model assessed the social representations (SRs) of ID specialists. RESULTS: All in all, 372 answers were analyzed. The positive elements related to the personal and professional qualities of ID specialists ('intellectual prestige", "open-mindedness"), in contrast with negative stereotypes related to their perceived daily life and practice characteristics ("hospital-based", "intense", "overspecialized"). Variables such as "I would not have chosen (or I won't choose) ID after the national ranking exam" and "I know someone who is an ID specialist" were associated with worse SR scores (p < 0.001 and p = 0.022 respectively). CONCLUSIONS: These findings provide insights into the attractiveness of ID as a specialty. Rounds in ID departments may enhance the interest of the specialty as a possible residency choice.

BACKGROUND: Radiology has always been an attractive specialty for residents, but its attractiveness has recently decreased in France regarding the median choice rank after at the National Residency Board. AIM: To study Radiologists' perceptions and social representations (SRs) among a group of medical students, residents and graduated physicians in France, to better understand the view of Radiologists to debunk stereotypes. METHODS: The nationwide web-based survey was based on valid hierarchical evocation methods. We determined the corpus's central core and SRs' principal themes with prototypical and correspondence factor analysis (CFA), respectively. RESULTS: Overall, 419 answers were analyzed. Radiologists' SRs were divided into 3 classes: negative stereotypes of Radiologists, negative stereotypes of the Radiologists' daily practice and Radiologists' skills. After multivariate analysis, variables that seemed to have a positive influence on Radiologists' SRs were considering radiology as a potential choice of specialty (p < 0.001) and the existence of practical experience in Radiology (p = 0.008). Women seemed to have a more negative SR of Radiologists than men (p = 0.035). DISCUSSION: This was the largest qualitative study on the subject and the only one among medical students, residents and graduated physicians, allowing a global picture. SRs of Radiologists seemed to be negative, potentially caused by poor knowledge of the Radiologists' profession. CONCLUSION: SRs of Radiologists among medical students and graduated physicians appears to be negative. Promoting the specialty among medical students and encouraging their immersion in a Radiology department could help to debunk many stereotypes about the daily life and missions of Radiologists.
