Subarachnoid hemorrhage (SAH) is a stroke subtype with high mortality and poor functional outcomes. Prompt occlusion of a ruptured aneurysm at an early stage is crucial to prevent rebleeding, which can result in even higher mortality and more severe disabilities. The most critical initial decision in SAH management is the choice of treatment method with surgical clipping or endovascular coiling. We aimed to develop an evidence-based clinical guideline to select the optimal initial treatment in patients with SAH. We developed this guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted across four databases (MEDLINE, Embase, Cochrane, and KoreaMed) to answer two population, intervention, comparison, outcome questions comparing clipping and coiling. The risk of bias was assessed using ROB 2.0 and the Newcastle-Ottawa Scale. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagrams and meta-analyses were generated for functional outcome and mortality. We included six randomized control trials (RCTs) and 58 observational studies. Meta-analysis of RCTs showed that coiling improved functional outcomes compared to clipping (odds ratio [OR], 0.91; 95% confidence interval [CI], 0.86–0.97). No significant mortality difference was observed in RCTs (OR, 1.38; 95% CI, 0.91–2.09), but non-RCTs favored clipping for reduced mortality (OR, 0.77; 95% CI, 0.69–0.86). However, it is difficult to generalize these findings to all clinical situations, as patients with SAH have a highly variable clinical course. Final treatment decision should be tailored to the individual patient’s status, including aneurysm location, morphology, and the expertise available at the treatment center. Such decisions are best made by specialists such as a board-certified physician and should be explained to the patient and their caregivers, along with the rationale for selecting the most appropriate treatment at the given hospital. Korea has many certified endovascular neurosurgeons, cerebrovascular surgeons, and certified cerebrovascular centers. Proper selection of the most suitable treatment method by certified physicians and centers would greatly benefit patient outcomes and healthcare professionals.

Accurate and early identification of stroke and large vessel occlusion (LVO) in emergency settings is essential for improving patient outcomes and ensuring the efficient allocation of medical resources. This clinical practice guideline systematically reviews domestic and international literature and conducts meta-analyses to evaluate the utility and diagnostic accuracy of stroke assessment tools used in prehospital emergency medical services (EMS). We developed a guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted to evaluate the usefulness of diagnostic EMS assessment tools for diagnosing stroke and LVO. Overall, 70 non-randomized control studies were selected for this study. A meta-analysis was conducted with a subgroup analysis to distinguish between patients with stroke and those with LVO. EMS tools demonstrated high sensitivity but low specificity for diagnosing stroke. In the prehospital setting, using validated EMS stroke assessment tools is recommended for the early identification of stroke and LVO. Upon hospital arrival, stroke specialists should conduct further evaluation and triage to confirm the diagnosis and guide appropriate management. Delays in diagnosing LVO are frequently unacceptable. While experts advocate for the use of EMS assessment tools to facilitate early identification of LVO, these tools alone lack adequate sensitivity. Therefore, further diagnostic evaluations and consultation with stroke specialists upon hospital arrival are recommended.

The mothership (MS) model, where patients are directly transferred to a thrombectomy-capable center, and the drip-and-ship (DS) model, where thrombolysis is initiated at the nearest primary stroke center before transfer for thrombectomy, are the primary transport modes for patients with stroke. We aimed to establish guidelines for selecting the appropriate transfer strategy based on emergent large vessel occlusion (LVO). We developed this guideline based on evidence from systematic reviews and meta-analyses via a de novo process. A systematic literature review was conducted across four databases (MEDLINE, Embase, Cochrane, and KoreaMed) to answer three Population, Intervention, Comparison, and Outcome questions comparing MS and DS models. The risk of bias was assessed using the Newcastle-Ottawa Scale. Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagrams and meta-analyses were generated for functional outcomes, mortality, and successful recanalization. Twenty-six non-randomized controlled studies showed that the MS model improved good functional outcomes by approximately 14% compared with the DS model (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.00–1.30). Fifteen studies reported that mortality in the MS and DS models showed no significant differences (OR, 0.97; 95% CI, 0.84–1.11). Twenty-four studies revealed no significant difference in successful recanalization between the MS and DS models (OR, 0.87; 95% CI, 0.68–1.10). The MS model should be considered first to improve the functional outcome of patients with LVO. However, if thrombectomy cannot be performed immediately after thrombolysis, or if a thrombectomy-enabled hospital is not nearby, the DS model should be considered by stroke specialists depending on transportation time and regional factors. We suggest a mixed approach with the DS model based on specific circumstances or regions to ensure the optimum treatment of patients with acute ischemic stroke (AIS). Appropriate transport for patients with LVO improves the prognosis of AIS.

Background: This study investigated the relationship between coronavirus disease 2019 (COVID-19), delirium, and 1-year mortality. Factors associated with delirium in COVID-19 patients were identified, along with the influence of psychotropic medications on delirium. Methods: The study used the South Korean National Health Insurance Service database.Adult COVID-19 patients diagnosed between October 2020 and December 2021 were included, with a propensity score-matched control group. Time-dependent Cox regression assessed associations among COVID-19, delirium, and mortality. Logistic regression analyzed the impact of psychotropic medications on delirium incidence. Results: The study included 832,602 individuals, with 416,301 COVID-19 patients. COVID-19 (hazard ratio [HR], 3.03; 95% confidence interval [CI], 2.92–3.13) and delirium (HR, 2.33;95% CI, 2.06–2.63) were independent risk factors for 1-year mortality. Comorbidities, insurance type, and residence were also related to mortality. Among COVID-19 patients, antipsychotic use was associated with lower delirium incidence (odds ratio [OR], 0.38; 95% CI, 0.30–0.47), while mood stabilizers (OR, 1.77; 95% CI, 1.40–2.21) and benzodiazepines (OR, 8.62; 95% CI, 7.46–9.97) were linked to higher delirium incidence. Conclusion COVID-19 and delirium are risk factors for 1-year mortality. Some factors associated with delirium in COVID-19 patients are modifiable and can be targeted in preventive and therapeutic interventions.

Objective: Interpersonal sensitivity, characterized by a heightened awareness of others’ behavior and emotions, is linked to mood disorders. However, current literature lacks a comprehensive analysis of how some items of the Interpersonal Sensitivity Measure (IPSM) interrelate and contribute to the overall construct. This study constructed a network for interpersonal sensitivity symptomatology to identify core IPSM items in patients with mood disorders. Methods: The IPSM, a 36-item self-report scale, was utilized to evaluate interpersonal sensitivity symptoms in 837 participants (major depressive disorder [MDD], n=265; bipolar I disorder [BD I], n=126; and bipolar II disorder [BD II], n=446). We performed exploratory graph analysis, employing regularized partial correlation models to estimate the network structure. Centrality analysis identified core IPSM symptoms for each mood disorder group. Network comparison tests assessed structural differences between the MDD and BD subgroups. Results: Network analysis detected five communities. Item 10 (“I worry about being criticized for things that I have said or done”) showed the highest value in strength. Multiple items on “Interpersonal Worry/Dependency” and “Low Self-Esteem” showed high strength centrality. Network structure invariance and global strength invariance test results indicated no significant differences between the MDD and BD subgroups. Conclusion Our findings emphasize the importance of addressing “Interpersonal Worry/Dependency” and “Low Self-Esteem” in the IPSM network among mood disorder patients based on core items of the network. Additionally, targeted treatments and comprehensive strategies in this aspect could be crucial for managing mood disorders.

Purpose: Accumulating evidence suggests that seafood and its components, such as eicosapentaenoic acid and docosahexaenoic acid, are known to prevent cardiovascular disease (CVD). However, little is known about whether sleep quality, which has been recognized as a risk factor for CVD, might influence these associations. Therefore, the purpose of the study was to investigate the longitudinal associations between seafood consumption and CVD in Korean adults with or without insomnia. Methods: The data were collected from the Korean Genome and Epidemiology Study (KoGES) and included 3,168 participants aged 40–69 years. Dietary intake was measured by a validated 106-item food-frequency questionnaire, and insomnia was assessed using a questionnaire on sleep-related symptoms. The CVD events included myocardial infarction, coronary artery disease, congestive heart failure, cerebrovascular disease, and peripheral vascular disease. Associations of seafood consumption with CVD were assessed using timedependent Cox regression analyses to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) while adjusting for potential confounding factors. Results: During the 8-year follow-up period, the incidence of CVD was 5.1%. There was a positive association between seafood consumption and most food groups, as well as nutrients. In contrast, as seafood consumption increased, the consumption of grains decreased. Regarding nutrient intake, there was a negative association between seafood consumption and carbohydrate intake. After adjustment for confounding factors, the risk of CVD was inversely associated with seafood consumption, with a 56% lower risk (HRT3 vs. T1 , 0.44; 95% CI, 0.26–0.75; p = 0.002), only in the non-insomnia group. Conclusion Findings from this study suggest that seafood consumption might lead to more favorable outcomes against CVD if accompanied by good sleep quality.

PURPOSE: The purpose of this study was to identify moderating and mediating effects of social support in the relationship between work-family conflict, job satisfaction and turnover intention among married women nurses. METHODS: The sample for this study consisted of 225 married female nurses from two hospitals located in Seoul. Data were collected through structured questionnaires and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and hierarchical multiple regression with the SPSS 21.0 program. RESULTS: (a) Social support of married female nurses had significant moderating and mediating effects between work-family conflict and job satisfaction. (b) Social support of married female nurses had significant moderating and mediating effects between work-family conflict and turnover intention. CONCLUSION: The results of the study indicate that social support is an important factor in work-family conflict, job satisfaction and turnover intention among married female nurses. Supervisor support is important to married nurses as social support as it is controlled by the organization. Therefore, supportive relationships based on mutual respect between supervisors and nurses are necessary for a creative organizational atmosphere and system.

BACKGROUND AND OBJECTIVES: The purpose of this study is to identify the prevalence of progressive dilation in patients with acute myocardial infarction (AMI) combined with heart failure (HF) and determine the prognostic significance and associated factors with a geometric change of an infarcted heart. SUBJECTS AND METHODS: A total of 1310 AMI patients with HF (63.9+/-12.5 years, 70% male) between November 2005 and April 2011 underwent echocardiography at admission and one year later. Left ventricular (LV) remodeling is defined as 20% progression, and left atria (LA) remodeling is 10% compared with the initial volume index. RESULTS: The prevalence of both LA and LV remodeling was 13.9%; LV only was 9.3%, LA only 22.8% and non-remodeling was 55.1%, respectively. In the non-remodeling group, Killip class II was more frequent (83.9%, p<0.001) whereas in other remodeling groups, Killip class III was more frequent. Initial wall motion score index, ejection fraction, maximal cardiac enzyme, high sensitive C-reactive protein, B type natriuretic peptide, and triglyceride serum levels were significantly associated with heart remodeling. All causes of death occurred in 168 cases (12.8%) during the follow-up period. Mortality was the highest in the LV and LA remodeling group (20.9%) and the lowest in the non-remodeling group (11.4%). During the period of follow-up, the cumulative survival rate was significantly lower in the groups of LA and LV remodeling than in others (log rank p=0.006). CONCLUSION: Total mortality was significantly increased in patients AMI with geometrically progressive LA and LV dilatation.
