Vietnam’s hedging amid U.S.-China Mekong rivalry: risk management under uncertainties

This paper examines how Vietnam has navigated U.S.-China rivalry in the Mekong basin while seeking to ensure its security, prosperity, and autonomy. I use the theoretical lens of hedging, defined as an insurance-maximising behaviour under conditions of high uncertainty. While existing scholarship has extensively examined Vietnam’s hedging on maritime security issues and the broader U.S.-China strategic and economic competition, this paper makes an empirical contribution by focusing on the relatively understudied angle of hedging in the Mekong basin context. I argue that Vietnam has hedged by (1) diversifying its Mekong partnerships with both the United States and China and (2) selectively cooperating with China under the Lancang-Mekong Cooperation. These acts aim to minimise Vietnam’s exposure to the long-term consequences of several non-traditional security risks, namely ecological challenges, water insecurity, economic vulnerabilities, and energy insecurity. Vietnam’s Mekong hedging also insures against the traditional security risks of big-power entrapment and military aggression as U.S.-China competition intensifies.

ORGANIZATIONAL AND FINANCIAL ASPECTS OF DISTRIBUTION MANAGEMENT OF DIGITAL CONTENT

In today's crisis conditions caused by military, financial, economic, social, environmental political upheavals and threats, the role of innovative technologies in trade is growing significantly. First of all, this applies to digital distribution in the book trade. Compared to traditional forms of trade, it does not require extensive infrastructure, large production facilities, or numerous staff. This helps to reduce transaction costs, respond more quickly to changing market conditions and simplify access to international trading platforms. However, the further development of digital distribution requires constant monitoring and analysis of global trends, and implementation of the best domestic and foreign practices to ensure efficient management of trading operations.The purpose of the study is to formulate the main financial and organizational measures to improve the management of digital distribution and increase its efficiency. To achieve this goal, the following tasks were solved: based on scientific publications and statistical data, the author monitored the trends in the development of digital distribution and the e-book market in Ukraine and in the world; analyzed the rank and level of visits to the websites of leading online e-book and audiobook stores in Ukraine; identified external and internal factors that affect the efficiency of digital distribution, in particular, e-books and audiobooks in the current conditions of military aggression and other risks; developed a model for generating revenue for a digital distribution platform.Financial, economic and organizational measures to improve the company's distribution management of digital content are proposed. These include areas of customer incentives and rewards, improved communication with digital goods manufacturers, priority funding for projects to improve the platform interface and mobile application, improved accounting, reporting, operational and strategic planning, and the introduction of artificial intelligence.

High prevalence of coronary artery calcium and aortic calcification in adults with repaired coarctation of the aorta and interrupted aortic arch

Abstract Background There is a high rate of late cardiovascular mortality in patients with repaired coarctation of the aorta (CoA) and interrupted aortic arch (IAA). Coronary artery calcium (CAC) is a marker of cardiovascular disease and there is growing evidence for aortic calcification as a predictor. Recent research in the general population suggests any CAC in males <35 years old and females ≤45 years places them at ≥90th percentile. Aims We aimed (1) to determine the prevalence of CAC, thoracic aorta calcification (TAC), and abdominal aorta calcification (AAC) in patients with CoA or IAA repair, and (2) to compare patients to a control group of Tetralogy of Fallot (TOF) patients, a condition with no known increased risk of atherosclerotic cardiovascular disease. Methods Retrospective cohort study of adult survivors of CoA/IAA repair followed up at an adult congenital heart disease (ACHD) clinic. Patients with at least 1 chest, abdomen, or pelvis computerised tomography (CT) scan for any indication were included. The presence/absence of calcification in the coronary arteries or aorta was assessed qualitatively. Patients on antihypertensive and statin therapy were considered hypertensive and hypercholesterolaemic, respectively. Patients were compared to adult survivors of TOF repair with CT scans for any indication (controls). Results Ninety-three CoA/IAA patients (87% CoA/13% IAA, median age at latest follow-up 34 years) had a total of 169 chest and 37 abdomen/pelvis CTs; 82, 93, and 37 patients had at least 1 CT suitable for CAC, TAC, and AAC review, respectively. CAC was present in 22% (18/82), TAC in 33% (31/93), and AAC in 23% (5/22) of CoA/IAA patients. CAC was present in 12% (18/153) and TAC in 11% (18/158) of TOF patients. CoA/IAA patients were more likely to have CAC and TAC than TOF patients (p=0.04 and p<0.0001; respectively) and be younger at the time of diagnosis (CAC p=0.03, TAC p=0.0001) despite TOF patients being older at time of latest CT scan (p=0.0003) (Table 1). Males aged <35 years and females ≤45 years represented 44% (8/18) of CoA/IAA patients with CAC. CoA/IAA patients with CAC were more likely to be hypertensive and hypercholesterolaemic than those without (78% [14/18] vs 48% [31/64], p=0.03; and 28% [5/18] vs 0% [0/64], p<0.0001; respectively) and was similar for TAC (hypertension p=0.005, hypercholesterolaemia p=0.04) but not AAC. After a mean follow-up of 11±7 years from first ACHD clinic, of the 93 patients, 2 patients died, 5 had coronary artery disease (at least mild stenosis on invasive angiography), 3 had a stroke, and 70% (65/93) were considered hypertensive at latest follow-up. Conclusions There is a high prevalence of CAC, aortic calcification, and hypertension in young adults with repaired CoA/IAA. Coronary and thoracic aortic calcification occurs at a younger age compared to controls. Further studies are warranted to assess the impact of aggressive cardiovascular risk reduction in this high-risk group.

Risk prediction models for incident heart failure: a systematic review and meta-analysis

Abstract Background Heart failure (HF) risk prediction models combine multivariable patient data to estimate an individual's risk of developing HF. By detecting at-risk and early-stage patients, models may facilitate earlier intervention to prevent or delay HF development. Previous systematic reviews were unable to recommend any existing prediction models for clinical use due to insufficient evidence and lack of guidelines on appraising study quality at their time of publication. Purpose To summarize the performance of risk prediction models for incident HF and identify models for further validation and potential clinical use. Methods We searched MEDLINE and EMBASE in June 2021 for English-language studies developing or validating HF risk prediction models. Studies were also retrieved from two previous systematic reviews. We narratively summarized model characteristics (e.g. model type, predictors used, prediction horizon) and study methodology (e.g. validation methods). Performance was assessed among all models validated in ≥ 1 cohort. For all models validated in ≥ 2 cohorts, we pooled discrimination measures using random-effects meta-analyses. Calibration was descriptively summarized based on individual study results from statistical tests and graph digitization of calibration plots. Study quality was assessed using the Prediction model Risk Of Bias ASsessment Tool (PROBAST). Results Of 18,937 publications screened, 41 studies consisting of 120 prediction models were included. Twenty models were both derived and validated, 99 only derived, and 1 only validated. Risk of bias was rated as high in nearly all (94.7%) PROBAST assessments, mostly attributable to issues with analysis. Among 21 models validated in ≥ 1 cohort, most had moderate (61.9%, C-statistic 0.7 to <0.8) or high (23.8%, C-statistic 0.8 to <0.9) discrimination. In patients with low predicted risk (<10%), the calibration was adequate. Nine (42.9%) of these 21 models were presented as web-based calculators and five (23.8%) as points-based risk scores. Based on performance, number of validation cohorts, study risk of bias, and user friendliness, the Atherosclerosis Risk in Communities (ARIC), Multi-Ethnic Study of Atherosclerosis (MESA), Pooled Cohort equations to Prevent Heart Failure (PCP-HF), and Health ABC models emerged as the most promising risk scores for clinical practice. Conclusions Given their acceptable performance but high risk of bias, future studies should focus on the external validation of these models in studies of high methodological rigor. Models should be validated in a greater diversity of patient populations, particularly with respect to race. Impact analyses assessing how the clinical implementation of these models affects patient outcomes are also required prior to their routine use. Once validated, these models may help guide clinical decision making to prevent the onset of HF with early, aggressive risk factor modification.Discrimination in 21 validated modelsCharacteristics of recommended models

Aggression in psychiatry: a bibliometric analysis

BackgroundAggression is a common problem in psychiatric clinics, and many studies have been conducted on the issue over the years. This study bibliometrically examines the characteristics and trends of aggression studies in psychiatry, such as the branches, publication years, types, publishers, and impact factors, and compares the focus areas of psychiatry and psychiatric nursing on aggression, to guide future research and readers on this topic. Bibliometric analysis was performed with network metrics, citation analysis, co-authorship analysis, science mapping, and network visualization techniques using WoS analysis reports and the VOSviewer program with data obtained from the Web of Science database on January 11, 2024.ResultsMost studies on aggression in psychiatry were published in 2019 as English articles. Then, 3.37% of these studies are in psychiatric nursing, mainly from Australia. In contrast, most psychiatric studies are from the USA. Psychiatry studies focus on causes, types, and relationships with psychiatric disorders, while psychiatric nursing studies emphasize aggressive attitudes, risk assessment, and aggression management.ConclusionsIt appears that studies on aggression continue to remain current in the literature and will continue to do so, considering that aggression is an ongoing clinical problem worldwide. Despite this, studies on assessing and managing the risk of aggression are still lacking. Future studies should prioritize the management of aggression. While the study showed the presence of multidisciplinary and international collaborations, it is recommended that these collaborations be further expanded. Findings may inform researchers’ keyword and journal choices.

Targeted Biopsy Is Sufficient for Men on Active Surveillance for Early-Stage Prostate Cancer.

Serial biopsy is a mainstay for patients on active surveillance (AS) for prostate cancer. mpMRI targeting has become a standard. It is unclear whether targeted biopsy alone reliably identifies the dominant lesion, thereby obviating the need for systematic sampling. Participants enrolled in AS with early-stage prostate cancer (PSA < 20, cT1-2, GG1-2) and underwent 2+ systematic biopsy sessions with or without MR-targeted sampling. The findings for dominant Gleason Grade (GG) and tumor localization were assessed. Among 821 men who underwent MR fusion biopsies, 82% were diagnosed with GG1 and 18% with GG2. Sixty-two percent had their first MR fusion biopsy as diagnostic or confirmatory. Across all fusion biopsies, MRI-targeted detection of GG and/or tumor location overlapped with systematic sampling for 95% of cases. For 5% of cases, systematic biopsy was unique in detecting GG and location outside the target. Most unique lesions detected outside the target had marginally aggressive features: 73% GG2 of low-volume and favorable histologic subtypes. In men with MR fusion biopsies, targeting alone identified the dominant GG and location most of the time (95%); 25% of dominant lesions were contiguous to the target, suggesting that better sampling of the target improves detection. The remaining 5% of men had higher-grade, low-volume disease outside the targeted lesion of which only 2% had aggressive risk features. MR fusion targeting, without systematic sampling, may be sufficient to monitor men on AS. Few high-risk cancers are missed, all of limited volume and favorable histology.

Aggressive Behaviour Risk Assessment Tool for Hospitalised Patients in Non-Psychiatric Inpatient Units.

To refine and validate an electronic version of the Aggressive Behaviour Risk Assessment Tool (ABRAT) and determine the sensitivity and specificity for identifying potentially violent patients in non-psychiatric inpatient units. A prospective cohort study design was used. All patients admitted or transferred to three inpatient units of an acute care hospital in Nebraska, USA, from 7 February to 9 April 2023, were included. The 10-item ABRAT assessments were performed daily for the first 3 days of admission. The violent events were collected until discharge in three categories: Physical aggression towards others, physical aggression towards property and verbal intimidation/threat towards others. Kendall's tau tests and a multivariate logistic regression procedure were performed to select a parsimonious set of items that best predict violent events. Of 1179 patients, 69 had ≥1 violent event (5.9%). The revised six-item tool with item weighting was named ABRAT for Hospitalised Patients (ABRAT-H). The area under the curve from the Receiver Operating Characteristics analysis was 0.82. The sensitivity and specificity at a cutoff score of two were 68.1% and 85.2%, respectively. As ABRAT-H scores increased, the percentage of violent patients also increased and for patients with scores ≥5, 55.2% became violent. ABRAT-H appears to be useful for identifying potentially violent patients in non-psychiatric inpatient units with satisfactory sensitivity and specificity. The availability of ABRAT-H may help provide focused preventive measures that target patients at high risk for violence and reduce violent events. A majority of the nursing workforce is employed in acute care hospital setting, and the availability of ABRAT-H can further enhance the culture of a safe work environment and have positive impacts not only on the nurses' physical and mental health but also on the quality of patient care. We have adhered to relevant STROBE guidelines for reporting observational studies. No Patient or Public Contribution.

7466 The Effects Of Various Forms Of Diabetes On Features Of Tumor Aggressiveness In Thyroid Cancer

Abstract Disclosure: R.D. Paparodis: None. E. Karvounis: None. A. Kapezanou: None. S. Livadas: None. G. Simeakis: None. D.P. Askitis: None. I. Androulakis: None. N.G. Angelopoulos: None. D. Zianni: None. A. Rizoulis: None. A. Boniakos: None. I. Perogamvros: None. D. Bantouna: None. J.C. Jaume: None. Introduction: Diabetes has been linked to increased risk for several cancers and aggressiveness of tumor behavior. A link between thyroid cancer and diabetes appears controversial in the literature as of yet. We designed the present study to assess whether autoimmune (type 1 + LADA = DM1) or type 2 diabetes (DM2) are associated with more aggressive thyroid cancers compared to those found in non-diabetic (non-DM) individuals. Methods: We retrospectively reviewed data from patients undergoing thyroid surgery in 10 Endocrinology and Endocrine Surgery Clinics throughout Greece over 2 years. We collected data on history and type of diabetes, pre-existing to the thyroid surgery, its treatments and duration, the preoperative thyroid function tests and the surgical pathology findings. We compared the incidence of various histological types of thyroid cancer and the features of tumor aggressiveness between patients with diabetes and those with normal glucose homeostasis (non-DM) (DM1 vs. DM2 vs. non-DM). Results: Overall, n=808 subjects with thyroid cancer were included: n=571 were females (70.7%), age 47.3 ± 14.3 years, BMI 27.0 ± 5.0 Kg/m2, mean TSH 1.99 ± 2.21 mIU/L; n= 692 were non-DM, n=10 had DM1 and n=107 had DM2. Histology revealed n=5 poorly differentiated / anaplastic, n=13 medullary, n=12 Hürthle cell, n=17 follicular and n=773 papillary thyroid cancers (PTC); n=20 (2.5%) with aggressive histological subtypes of PTC, n=5 (0.6%) with distant metastases (MET), n=199 (24.6%) with extrathyroidal extension (ETE), n=419 (51.9%) with capsular invasion (CI), n=225 (27.8%) with lymph nodes involvement (LNi) and n=23 with cancer recurrence (CR) (2.8%). The incidence of aggressive histological types, CR, MET or number of I-131 treatments were not different between groups (p&amp;gt;0.05). ETE, CI and LNi were significantly more common in non-DM compared to both diabetes groups, while gross ETE was more common in DM2 over DM1 and non-DM (p&amp;lt;0.001). Conclusions: More DM1 than DM2 seem to confer a protective effect on several features of cancer aggressiveness in affected individuals. On the other hand, more DM2 than DM1 seems to significantly promote gross ETE. No effect was observed pertaining to the risk for more aggressive tumors or histological subtypes of PTC. Although aggressiveness of thyroid cancer seems controlled in DM1 and to a lesser degree in DM2 the complex interplay between autoimmunity, hyperglycemia and thyroid cancer biology requires larger sample size to better determine causative effects.

7119 Klinefelter Syndrome in a Tertiary Referral Clinic: A Case Series and Clinical Audit

Abstract Disclosure: J. Luo: None. S. Sarlos: None. R. Giri: None. I. Sim: None. R.I. McLachlan: None. C.A. Allan: None. R. Upreti: None. Background: Klinefelter syndrome, the most common chromosomal disorder in men, remains underdiagnosed in many of those affected. Klinefelter syndrome is associated with hypogonadism and infertility, as well as an increased risk for venous thromboembolism (VTE), cardiometabolic disease, osteoporosis and gynaecomastia in adults. We studied the clinical features and disease associations in a tertiary referral cohort, and audited the care provided. Methods: Following ethics approval, adult patients with Klinefelter syndrome attending a Clinical Andrology Service in a tertiary Australian institution since 1 January 2011 were recruited. A database was established and demographics, aspects of initial diagnosis, ongoing treatments and comorbidities were documented. We audited our care using the European Academy of Andrology 2021 Guidelines for Klinefelter Syndrome. Results: Of 94 patients eligible, 57 patients consented to participation. The median age of diagnosis was 28 years, with the most common karyotype being 47,XXY (74%), followed by mosaic (20%) and higher degree polysomy (6%). Infertility (44%) and hypogonadism (33%) were the most common reasons for diagnosis. Most patients (88%) were treated with testosterone. Five men (11%) had genetic children with seven (18%) having previously attempted surgical sperm extraction. VTE occurred in seven patients (12%), with five on long-term anticoagulation following VTE diagnosis. Cardiovascular risk factor prevalence assessed at a median age of 42 years included increased BMI (72%), hypertension (25%), dyslipidaemia (70%), tobacco use (26%), impaired fasting glucose (11%) and type 2 diabetes (22%), though only one patient had a previous cardiovascular event. Osteopenia and osteoporosis were present in 28% and 4% of patients respectively, though only two patients had minimal trauma fractures. The audit of longitudinal care showed that gynaecomastia status was underreported (42%) in our clinic, whilst assessment and management of other health domains were mostly in keeping with the current recommendations. Conclusions: Klinefelter syndrome diagnosis continues to be delayed until adulthood in many men, with presentations most commonly involving infertility and/or hypogonadism. Our tertiary cohort demonstrates low rates of fertility treatment and success, which is likely multifactorial. There is a high burden of VTE, cardiovascular risk factors and reduced bone density despite testosterone treatment. Low rates of cardiovascular events and fracture may be reflective of a younger cohort as well as more aggressive risk factor management in a sub-specialist service. Gynaecomastia identification, documentation and management are areas for potential improvement. Increased awareness of Klinefelter syndrome and research into its associated risks are essential for standardising care and improving long-term outcomes. Presentation: 6/1/2024

The association of anatomical renal mass complexity with surgical approach, Hb drop, and the rate of blood transfusion.

The third most prevalent malignant neoplasm involving the urinary tract is renal cell carcinoma (RCC), encompassing nearly 3.5% of the entire cancers afflicting the body. The aim of this research was to explore how the R.E.N.A.L. nephrometry score relates to the decisions made regarding surgery in individuals with localized RCC. This prospective study, assessed patients with localized parenchymal renal masses (stages I and II) tentatively diagnosed as RCC. Utilizing preoperative multiphasic renal CT scans and MRI, the R.E.N.A.L. score categorized masses for nephrometry values. Inclusion criteria involved collecting patient data, and data collection utilizing a structured format focusing on the nephrometry grading system. The study included 64 patients aged (mean ± SD) 49.78 ± 12.35 yrs. Undergoing renal mass surgery, there were 17 (26.5%) low, 28 (43.8%) moderate and 19 (29.7%) high-complexity lesions. All patients with a low Nephrometry score (n = 17) underwent partial nephrectomy, and all cases with a high score (n = 19) underwent radical nephrectomy. For those with a moderate Nephrometry score (n = 28), 13 (46.4%) underwent partial nephrectomy, while the remaining 15 (53.6%) cases underwent radical nephrectomy. Morbidity was low, and no mortality occurred at 180 days. Patients who had lesions fully above or below polar lines were less likely to need blood transfusions. A trend towards higher Fuhrman grades in patients receiving transfusions suggests a potential link between tumor aggressiveness and bleeding risk. Our findings provide insight on the utilization of the R.E.N.A.L. nephrometry score in forecasting perioperative, post-surgical, and oncological results. Such data might help optimize surgical methods and pre-operative patient counseling.

Does Adopting Western Low-density Lipoprotein Cholesterol Targets Expose Indians to a Higher Risk of Cardiovascular Events? Expert Opinion From the Lipid Association of India.

Adverse cardiovascular (CV) events have declined in Western countries due at least in part to aggressive risk factor control, including dyslipidemia management. The American and European (Western) dyslipidemia treatment guidelines have contributed significantly to the reduction in atherosclerotic cardiovascular disease (ASCVD) incidence in the respective populations. However, their direct extrapolation to Indian patients does not seem appropriate for the reasons described below. In the US, mean low-density lipoprotein cholesterol (LDL-C) levels have markedly declined over the last 2 decades, correlating with a proportional reduction in CV events. Conversely, poor risk factor control and dyslipidemia management have led to increased CV and coronary artery disease (CAD) mortality rates in India. The population-attributable risk of dyslipidemia is about 50% for myocardial infarction, signifying its major role in CV events. In addition, the pattern of dyslipidemia in Indians differs considerably from that in Western populations, requiring unique strategies for lipid management in Indians and modified treatment targets. The Lipid Association of India (LAI) recognized the need for tailored LDL-C targets for Indians and recommended lower targets compared to Western guidelines. For individuals with established ASCVD or diabetes with additional risk factors, an LDL-C target of <50 mg/dL was recommended, with an optional target of ≤30 mg/dL for individuals at extremely high risk. There are several reasons that necessitate these lower targets. In Indian subjects, CAD develops 10 years earlier than in Western populations and is more malignant. Additionally, Indians experience higher CAD mortality despite having lower basal LDL-C levels, requiring greater LDL-C reduction to achieve a comparable CV event reduction. The Indian Council for Medical Research-India Diabetes study described a high prevalence of dyslipidemia among Indians, characterized by relatively lower LDL-C levels, higher triglyceride levels, and lower high-density lipoprotein cholesterol (HDL-C) levels compared to Western populations. About 30% of Indians have hypertriglyceridemia, aggravating ASCVD risk and complicating dyslipidemia management. The levels of atherogenic triglyceride-rich lipoproteins, including remnant lipoproteins, are increased in hypertriglyceridemia and are predictive of CV events. Hypertriglyceridemia is also associated with higher levels of small, dense LDL particles, which are more atherogenic, and higher levels of apolipoprotein B (Apo B), reflecting a higher burden of circulating atherogenic lipoprotein particles. A high prevalence of low HDL-C, which is often dysfunctional, and elevated lipoprotein(a) [Lp(a)] levels further contribute to the heightened atherogenicity and premature CAD in Indians. Considering the unique characteristics of atherogenic dyslipidemia in Indians, lower LDL-C, non-HDL-C, and Apo B goals compared to Western guidelines are required for effective control of ASCVD risk in Indians. South Asian ancestry is identified as a risk enhancer in the American lipid management guidelines, highlighting the elevated ASCVD risk of Indian and other South Asian individuals, suggesting a need for more aggressive LDL-C lowering in such individuals. Hence, the LDL-C goals recommended by the Western guidelines may be excessively high for Indians and could result in significant residual ASCVD risk attributable to inadequate LDL-C lowering. Further, the results of Mendelian randomization studies have shown that lowering LDL-C by 5-10 mg/dL reduces CV risk by 8-18%. The lower LDL-C targets proposed by LAI can yield these incremental benefits. In conclusion, Western LDL-C targets may not be suitable for Indian subjects, given the earlier presentation of ASCVD at lower LDL-C levels. They may result in greater CV events that could otherwise be prevented with lower LDL-C targets. The atherogenic dyslipidemia in Indian individuals necessitates more aggressive LDL-C and non-HDL-C lowering, as recommended by the LAI, in order to stem the epidemic of ASCVD in India.

Risky Business. Interventions to Prevent Aggression Against Health Workers From Patients at Risk: An Integrative Review.

To identify best practices to prevent violence against healthcare workers by patients at risk for aggression in the adult inpatient setting. An integrative review. Conducted using the Johns Hopkins Evidence-based Practice for Nurses and Healthcare Professionals Model. Title and abstract screening on 4186 articles resulted in 156 for full text review. Full text screening yielded 14 articles that met inclusion criteria. A search of the databases PubMed, CINAHL, Embase, and JBI from January 2019 to February 2023. The review revealed behavioural intervention teams, environmental changes, and coordinated communication plans were the most used strategies, however none demonstrated significant decreases in violence. Health systems can implement strategies shown to decrease the incidence of violence in healthcare settings globally. Lack of consistency in the evidence suggests the need for further research to assess mitigating strategies for violence against healthcare workers in inpatient hospital settings. Patient safety is a cornerstone of nursing practice; however, healthcare workers need to feel safe in their work environment. Violent events are chronically underreported, ill defined, and when reported, do not address change in the practice setting. Identifying strategies to address escalating behaviour before it results in violence is crucial for everyone's safety. This integrative review exposes the scarcity of evidence available to address rising concerns about patients on healthcare provider violence (Type II) in the workplace. Although several assessment tools for identifying violent patients exist, evidence regarding prevention is woefully absent. The review highlights potential interventions for further study to equip healthcare workers to manage patients safely and effectively before an escalation occurs.

Prior Sexual Aggression as a Moderator of an Integrated Alcohol and Sexual Assault Prevention Program for Heavy Drinking College Men: A Brief Report.

Sexual aggression and heavy drinking are interrelated concerns among college men. As a result, integrated prevention interventions now exist to address co-occurring risk for sexual aggression and heavy drinking. The Sexual Assault and Alcohol Feedback and Education (SAFE) program is a multi-session integrated alcohol and sexual assault prevention program for college men that addresses alcohol use, sexual activity, social norms, alcohol-related sexual consequences, understanding of consent, and engagement in bystander intervention. Given that prior sexual aggression is a risk factor for subsequent perpetration of sexual aggression, the present study examined whether the effect of SAFE on a range of outcomes (rape myth acceptance, hypergender ideology, labeling of consent, and bystander intervention intentions) depended on men's baseline history of perpetration. Participants in the study were heavy drinking college men (N = 115) randomly assigned to SAFE or a mindfulness-based control condition, and who completed follow-ups at two and six months. Data were analyzed using multilevel modeling. Degree of prior sexual aggression significantly moderated effects of SAFE on change in intentions to intervene, as well as rape myth acceptance, between baseline and six months. As baseline perpetration decreased, those receiving SAFE significantly increased bystander intervention intentions more so than the control group. As baseline perpetration increased, those receiving SAFE significantly increased rape myth acceptance more so than the control group. Findings emphasize the importance of continued examination of who benefits from integrated alcohol and sexual assault prevention programs.

The role of changes in peer victimization from elementary to high school and autonomic reactivity on adolescent reactive aggression.

The goals of the present study were to investigate links between changes in peer victimization from elementary to high school and adolescent reactive aggression (Goal 1), whether heightened autonomic nervous system (ANS) reactivity to social and nonsocial stress increases risk for adolescent reactive aggression (Goal 2), and whether increased ANS reactivity strengthens the association between changes in victimization and adolescent reactive aggression (Goal 3). Participants included 145 adolescents (Mage = 16; 54% female; 76% European American, 13% African American, 11% Latino American, 7% Asian American, 5% of mixed race or ethnicity; 60% with family incomes of $100,000 or greater). We collected self-report data in elementary (Time 1 [T1]); (Time 2 [T2]); middle (Time 3 [T3]); and high school (Time 4 [T4]) to assess victimization. At T4, we measured self-reported reactive and proactive aggression, and ANS reactivity (preejection period [PEP], respiratory sinus arrhythmia [RSA]) to peer rejection and nonsocial frustration. More positive victimization slope over time (meaning both less decreasing slopes and increasing slopes) predicted greater adolescent reactive, but not proactive aggression (Goal 1). Greater RSA augmentation to peer rejection and more PEP reactivity to nonsocial frustration predicted more reactive, but not proactive aggression (Goal 2). The link between victimization slope and reactive aggression emerged only for adolescents exhibiting RSA augmentation to peer rejection (marginal; Goal 3).

Metabolic syndrome traits differentially and cumulatively influence micro- and macrovascular disease risk in patients with MASLD.

The cumulative impact of metabolic syndrome (MetS) components on micro- and macrovascular disease in metabolic dysfunction-associated steatotic liver disease (MASLD) is unclear. We aimed to determine whether the number of the MetS components increases the risk of micro- and macrovascular disease in patients with MASLD. We performed a retrospective cohort study of electronic medical records using the TriNetX network, a global federated database. The exposure arm was patients with hepatic steatosis (defined via International Classification of Diseases, 10th Revision coding, or modified hepatic steatosis index), and ≥1 MetS components (obesity/central adiposity, insulin resistance, hypertension, or dyslipidaemia), compared with a reference arm of adults without any MetS components or hepatic steatosis. Our propensity score matched (1:1) for confounders with 5 years of follow-up. Primary outcomes included microvascular (peripheral neuropathy, retinopathy, and nephropathy) and macrovascular (cardiovascular events, cerebrovascular accidents, and peripheral vascular disease) disease. Secondary analyses assessed the impact of additional MetS components on these outcomes, as well as the impact of sex. MASLD, defined by hepatic steatosis and insulin resistance (n = 15 937), carried the highest risk of microvascular disease (HR 13.93 (95% CI 8.55-22.68)), whilst MASLD, defined by hepatic steatosis and hypertension (n = 53 028), carried the highest risk of macrovascular disease (7.23 (6.45-8.13)). MASLD with all MetS components carried greatest risk of both micro- (31.20 (28.88-33.70) (n = 462 789)) and macrovascular (8.04 (7.33-8.82) (n = 336 010)) disease. We demonstrate a differential effect of MetS components on micro- and macrovascular disease risk in patients with MASLD, with a cumulative impact of multiple MetS on overall risk. The impact of MetS components was most pronounced in women. Aggressive metabolic risk factor management is critical for prevention of micro- and macrovascular complications.

Platelet and epithelial cell interations can be modeled in cell culture, and are not affected by dihomo-gamma-linolenic acid.

Increasing evidence is implicating roles for platelets in the development and progression of ovarian cancer, a highly lethal disease that can arise from the fallopian tubes, and has no current method of early detection or prevention. Thrombosis is a major cause of mortality of ovarian cancer patients suggesting that the cancer alters platelet behavior. The objective of this study was to develop a cell culture model of the pathological interactions of human platelets and ovarian cancer cells, using normal FT epithelial cells as a healthy control, and to test effects of the anti-platelet dihomo-gamma-linolenic acid (DGLA) in the model. Both healthy and cancer cells caused platelet aggregation, however platelets only affected spheroid formation by cancer cells and had no effect on healthy cell spheroid formation. When naturally-formed spheroids of epithelial cells were exposed to platelets in transwell inserts that did not allow direct interactions of the two cell types, platelets caused increased size of the spheroids formed by cancer cells, but not healthy cells. When cancer cell spheroids formed using magnetic nanoshuttle technology were put in direct physical contact with platelets, the platelets caused spheroid condensation. In ovarian cancer cells, DGLA promoted epithelial-to-mesenchymal (EMT) transition at doses as low as 100 μM, and inhibited metabolic viability and induced apoptosis at doses ≥150 μM. DGLA doses ≤150 μM used to avoid direct DGLA effects on cancer cells, had no effect on the pathological interactions of platelets and ovarian cancer cells in our models. These results demonstrate that the pathological interactions of platelets with ovarian cancer cells can be modeled in cell culture, and that DGLA has no effect on these interactions, suggesting that targeting platelets is a rational approach for reducing cancer aggressiveness and thrombosis risk in ovarian cancer patients, however DGLA is not an appropriate candidate for this strategy.

Poor Work Ability Is Associated with Workplace Violence in Nurses: A Two-Wave Panel Data Analysis.

Healthcare personnel must deal with two problems of growing importance: violence in the workplace and the loss of work ability due to the aging of the workforce. Our objective was to evaluate, with a two-wave perspective design, the relationships of work ability, social support, and occupational stress with workplace violence in nurses. In an Italian public health company, we asked nurses to self-assess their work ability using the Work Ability Index (WAI) and we analyzed the relationship between this indicator and the violence experienced in the previous and following years. A total of 321 out of 344 nurses (99.3%) participated. In a logistic regression model, the WAI score was a significant protective factor for violence experienced in the previous year (OR = 0.94 CI95% = 0.90; 0.98 p < 0.01) and in the following year (OR = 0.88 CI95% = 0.84; 0.92 p < 0.01). In a hierarchical logistic regression model, social support acted as a protective factor (OR = 0.87 CI95% = 0.79; 0.95 for violence experienced in the previous year), while occupational stress was a significant determinant of the risk of aggression (OR = 3.65 CI95% = 1.90; 7.03 in the previous year, OR = 3.54 CI95% = 1.801; 6.947 in the following year). The difficulties that nurses encounter in carrying out their growing work demands in an environment that is not promptly adapted to their changing physical and mental states can lead to an increased risk of violence. Prevention of workplace violence should include organizational and ergonomic measures that reduce stress and increase staff support and work ability.

Predictive Ability of the Dynamic Appraisal of Situational Aggression-Inpatient Version (DASA-IV) in Medical-Surgical Units.

Workplace violence persists in health care with nurses reporting physical and verbal abuse from aggressive patients causing emotional stress and lost workdays. The Dynamic Appraisal of Situational Aggression-Inpatient Version (DASA-IV) was developed to measure risk for aggression in patients with behavioral health conditions in psychiatric and emergency department settings. The DASA-IV has not been validated with adult patients admitted to medical-surgical units. To determine whether DASA-IV scores are predictive of aggressive events in adults hospitalized on medical-surgical units. This multisite study used a case-control design. DASA-IV scores and acts of aggression were extracted from the medical record retrospectively to validate the appraisal's predictability. Receiver operating characteristic (ROC) and area under the curve (AUC) were used to correlate DASA-IV scores with aggressive events. DASA-IV assessments (N=156 999; mean [SD] 10.1 [10.7]/patient; range 1-220) were collected from 13 611 patients. Patients were primarily White (86.1%) and female (51.7%). Aggression (n = 509 patients; 3.7%) was significantly associated with older age, male sex, smoking, illicit drug use, and high DASA-IV scores. AUC of the ROC analysis for the DASA-IV showed a 97% probability (95% confidence interval [CI] 0.964-0.977) that an aggressive patient would have a higher score on the DASA-IV than a nonaggressive patient. Binary logistic regression predicted that for every point increase in the DASA-IV, there was a 3.51 (95% CI 3.38-3.63) times increased risk for aggression (B = 1.255, SE = 0.18, Wald = 4766.6, P < .001). This study is the first to validate use of the DASA-IV in medical-surgical populations, demonstrating predictive ability for aggressive incidents. The DASA-IV can be used successfully in medical-surgical populations for early identification of potential aggression.
