RESUMO
BACKGROUND: Hyperuricemia could be a risk for various chronic diseases, and it could be largely corrected by diet control. This study was a nationwide cross-sectional study to investigate the association between serum uric acid level and dietary fiber intake. METHODS: This study analyzed data based on the Korean National Health and Nutrition Examination Survey conducted from 2016 to 2018. Adults over 20 years of age with normal renal function, defined as an estimated glomerular filtration rate (eGFR) over 30mL/min/1.73m2, were included. The criteria for hyperuricemia were ≥ 7 mg/dL in men and ≥ 6 mg/dL in women. Data regarding dietary intake were obtained using the 24-hour recall method. RESULTS: A total of 15,278 subjects (6,455 males/8,823 females) were analyzed. The prevalence of hyperuricemia was 19.3% in men and 6.8% in women. There were significant, negative associations between serum uric acid and total fiber intake in both men and women. Consuming more than 27.9 g of dietary fiber in men and 20.7 g in women reduced the risk of hyperuricemia by approximately 30% with odds ratios of 0.72 (0.62-0.83) and 0.71 (0.56-0.88) in men and women, respectively. With regard to the risk reduction by the type of dietary fiber, cereal fiber was significantly identified in both men and women, while fruit fiber was only significant in men. In the subgroup analysis, this association remained significantly in young and metabolically healthy populations with normal weight. CONCLUSIONS: Dietary fiber intake was inversely associated with serum uric acid levels. This relationship was particularly significant in metabolically healthy young adults.
RESUMO
Background: The TALOS-AMI study highlighted the effectiveness of a de-escalation strategy shifting from ticagrelor to clopidogrel 1 month after percutaneous coronary intervention (PCI), resulting in significant reduction in clinical events, primarily attributed to a substantial decrease in bleeding events. Nevertheless, the impact of this strategy on outcomes based on sex remains unclear. Methods: This was a post-hoc analysis of the TALOS-AMI study. At 1 month after PCI, patients who remained adherent to aspirin and ticagrelor without experiencing major adverse events were randomized into either the de-escalation group (clopidogrel plus aspirin) or the active control group (ticagrelor plus aspirin) for an additional 12 months. The primary endpoint encompassed a composite of cardiovascular death, myocardial infarction, stroke, and Bleeding Academic Research Consortium bleeding type 2 or greater at 12 months after randomization. Results: Among the 2,697 patients included in this study, 454 (16.8%) were women. Women, characterized by older age and a higher prevalence of hypertension, diabetes, impaired renal function, and non-ST-segment myocardial infarction, exhibited a lower primary endpoint at 12 months compared to men [adjusted hazards ratio (HR), 0.60; 95% confidence interval (CI), 0.37-0.95; P = 0.03]. Compare to the active control group, the de-escalation group demonstrated a reduced risk of the primary endpoint in both women (adjusted HR, 0.38; 95% CI, 0.15-0.95; P = 0.039) and men (adjusted HR, 0.56; 95% CI, 0.40-0.79; P = 0.001) (interaction P = 0.46). Conclusions: In stabilized patients post-PCI with drug-eluting stents for acute myocardial infarction, the primary endpoint was lower among women compared to men. In this cohort, the benefits of an unguided de-escalation strategy from ticagrelor to clopidogrel were comparable in women and men.
RESUMO
BACKGROUND/AIMS: Since the coronavirus disease 2019 (COVID-19) outbreak, hospitals have implemented infection control measures to minimize the spread of the virus within facilities. This study aimed to investigate the impact of COVID-19 on the incidence of healthcare-associated infections (HCAIs) and common respiratory virus (cRV) infections in hematology units. METHODS: This retrospective study included all patients hospitalized in Catholic Hematology Hospital between 2019 and 2020. Patients infected with vancomycin-resistant Enterococci (VRE), carbapenemase-producing Enterobacterales (CPE), Clostridium difficile infection (CDI), and cRV were analyzed. The incidence rate ratio (IRR) methods and interrupted time series analyses were performed to compare the incidence rates before and after the pandemic. RESULTS: The incidence rates of CPE and VRE did not differ between the two periods. However, the incidence of CDI increased significantly (IRR: 1.41 [p = 0.002]) after the COVID-19 pandemic. The incidence of cRV infection decreased by 76% after the COVID-19 outbreak (IRR: 0.240 [p < 0.001]). The incidence of adenovirus, parainfluenza virus, and rhinovirus infection significantly decreased in the COVID-19 period (IRRs: 0.087 [p = 0.003], 0.031 [p < 0.001], and 0.149 [p < 0.001], respectively). CONCLUSION: The implementation of COVID-19 infection control measures reduced the incidence of cRV infection. However, CDI increased significantly and incidence rates of CPE and VRE remained unchanged in hematological patients after the pandemic. Infection control measures suitable for each type of HCAI, such as stringent hand washing for CDI and enough isolation capacities, should be implemented and maintained in future pandemics, especially in immunocompromised patients.

PURPOSE: To determine the cut-off points of minimum linear diameter (MLD) and base diameter (BD) at which the progression rate of idiopathic full-thickness macular holes (MHs) decreases before vitrectomy. STUDY DESIGN: A retrospective study. METHODS: We investigated the differences in MLD and BD between baseline and operation days in patients with stages 2, 3, and 4 MHs using optical coherence tomography (OCT). Each difference in OCT parameters was divided by the time interval to calculate the MH progression rates and the cut-off points of MLD and BD. RESULTS: Overall, 269 patients (282 eyes) were included. It took an average of 36.02 ± 24.69 (7-197) days from baseline to operation. MLD and BD progressed faster in stages 2 and 3 without posterior vitreous detachment (PVD) than in stage 4 with PVD (MLD: p < 0.001 and p = 0.007; BD: p < 0.001 and p = 0.019, respectively). Simple linear regression showed the relationship between baseline MLD and BD, and the progression rate; the progression rate decreased as baseline MLD (p = 0.004) and BD increased ( p < 0.001). For baseline MLD and BD, the cut-off points where the progression rate decreased were 306.0 and 470.0 µm, respectively. CONCLUSION: The group without PVD progressed faster than the group with PVD. Moreover, the progression rates were faster in MHs with MLD < 306.0 µm and BD < 470.0 µm. In these patients, vitrectomy without delay is expected to improve the visual prognosis.

OBJECTIVES: To test the hypothesis that tobacco exposure is associated with elevated blood pressure (EBP) in Korean adolescents, and that the association is dose dependent. METHODS: This cross-sectional study used data from the 2011-2020 Korea National Health and Nutrition Survey (KNHANES). Subjects were eligible if they were 13-18 years at the time of participation in KNHANES. Tobacco exposure was defined by urine cotinine level. The main outcomes were EBP and hypertension. Statistical analyses were conducted using SAS version 9.4 with appropriate sampling weights to account for the complex survey design, stratification, and cluster variable. RESULTS: A total of 2,518 adolescents was included in the analysis, representing 2.5 million Korean adolescents. The mean± standard deviation participant age was 15.3±1.7 years, and 55.3% were male. The number of participants with active tobacco smoke exposure was 283 (11.2%), passive tobacco smoke exposure was 145 (5.8%), and no smoke exposure was 2,090 (83.0%). Analysis of the 2,518 urine-cotinine-verified participants showed that tobacco smoke exposure had a significant effect on EBP: with an odds of elevated blood pressure of 3.00 (95% confidence interval [CI], 1.14 to 7.89). The odds of hypertension were 3.61 (95% CI, 1.13 to 11.49) in the active smoking group compared with the no tobacco exposure group after adjustment for potential confounders. CONCLUSIONS: It is necessary to present a range of public health plans to reduce tobacco exposure that affects adolescents' blood pressure, and further research with a larger number of participants using urine cotinine as a biomarker is needed.

The importance of appropriate and intensive follow-up management for individuals identified with suicide risk through screening is highlighted. The Link between Primary Care Clinic and Public Health Resources Intervention(LinkPC-PH), a suicide prevention program in primary care clinics supported by community public health resources, was implemented at the district level in 2017. The purpose of the present study is to evaluate the effectiveness of the LinkPC-PH intervention by comparing suicide rates before(2014-2016) and after(2017-2019) implementation of the intervention using a difference-in-differences design. The LinkPC-PH comprises several dimensions of intervention including screening, risk assessment of suicidality, and referral in primary care clinics and crisis contact within 24 hours, case management, and safety planning led by public health professionals. After adjustment for district-level confounders, an intervention-implemented district had 2.87 fewer suicide deaths per 100,000 people in a population sample at post-intervention than would have been expected from the same trend in suicide rates as non-implemented intervention districts. In other words, the suicide rate in the intervention area decreased by 25% following the intervention. These results empirically substantiate suicide prevention programs in primary care clinics by community public health resources for reduced suicide rates to support effective community-based suicide prevention interventions.

Importance: In patients with acute myocardial infarction (AMI) who have high ischemic risk, data on the efficacy and safety of the de-escalation strategy of switching from ticagrelor to clopidogrel are lacking. Objective: To evaluate the outcomes of the de-escalation strategy compared with dual antiplatelet therapy (DAPT) with ticagrelor in stabilized patients with AMI and high ischemic risk following percutaneous coronary intervention (PCI). Design, Setting, and Participants: This was a post hoc analysis of the Ticagrelor vs Clopidogrel in Stabilized Patients With Acute Myocardial Infarction (TALOS-AMI) trial, an open-label, assessor-blinded, multicenter, randomized clinical trial. Patients with AMI who had no event during 1 month of ticagrelor-based DAPT after PCI were included. High ischemic risk was defined as having a history of diabetes or chronic kidney disease, multivessel PCI, at least 3 lesions treated, total stent length greater than 60 mm, at least 3 stents implanted, left main PCI, or bifurcation PCI with at least 2 stents. Data were collected from February 14, 2014, to January 21, 2021, and analyzed from December 1, 2021, to June 30, 2022. Intervention: Patients were randomly assigned to either de-escalation from ticagrelor to clopidogrel or ticagrelor-based DAPT. Main Outcomes and Measures: Ischemic outcomes (composite of cardiovascular death, myocardial infarction, ischemic stroke, ischemia-driven revascularization, or stent thrombosis) and bleeding outcomes (Bleeding Academic Research Consortium type 2, 3, or 5 bleeding) were evaluated. Results: Of 2697 patients with AMI (mean [SD] age, 60.0 [11.4] years; 454 [16.8%] female), 1371 (50.8%; 684 assigned to de-escalation and 687 assigned to ticagrelor-based DAPT) had high ischemic risk features and a significantly higher risk of ischemic outcomes than those without high ischemic risk (1326 patients [49.2%], including 665 assigned to de-escalation and 661 assigned to ticagrelor-based DAPT) (hazard ratio [HR], 1.74; 95% CI, 1.15-2.63; P = .01). De-escalation to clopidogrel, compared with ticagrelor-based DAPT, showed no significant difference in ischemic risk across the high ischemic risk group (HR, 0.88; 95% CI, 0.54-1.45; P = .62) and the non-high ischemic risk group (HR, 0.65; 95% CI, 0.33-1.28; P = .21), without heterogeneity (P for interaction = .47). The bleeding risk of the de-escalation group was consistent in both the high ischemic risk group (HR, 0.64; 95% CI, 0.37-1.11; P = .11) and the non-high ischemic risk group (HR, 0.42; 95% CI, 0.24-0.75; P = .003), without heterogeneity (P for interaction = .32). Conclusions and Relevance: In stabilized patients with AMI, the ischemic and bleeding outcomes of an unguided de-escalation strategy with clopidogrel compared with a ticagrelor-based DAPT strategy were consistent without significant interaction, regardless of the presence of high ischemic risk.
