RESUMO
BACKGROUND: Particulate matter (PM) is known to contain heavy metals and be harmful to the tissues and organs of the human body including the eyes. As such, in this study, the deposition of heavy metals from PM on soft contact lenses was examined, and changes in the lens parameters were further investigated. METHODS: Six types of soft contact lenses were exposed to captured PM10 for eight hours. The central thickness, water content, refractive power, and oxygen transmissibility of each contact lens were measured after analyzing the amounts of six heavy metals adsorbed on the contact lenses. RESULTS: Lead, manganese, barium, arsenic, vanadium, and cadmium were detected in the captured PM, and only lead was adsorbed on all soft contact lenses except senofilcon C. The largest deposition was 23.21 ± 0.70 (10- 3)µg/lens of the lead on lotrafilcon B. The oxygen transmissibility of nelfilcon A exhibited statistically significant changes, however, it was within the ISO standard tolerance. Nevertheless, changes in the central thickness, water content, and refractive power of each soft contact lens were not statistically significant. CONCLUSIONS: This study revealed that a considerable amount of lead in PM10 was adsorbed on soft contact lenses. Amongst lens parameters, only oxygen transmissibility changed significantly. Thus, wearing soft contact lenses under high PM10 concentration might affect the physiology of the eyes.

BACKGROUND: COVID-19 is an ongoing global health crisis with prevention and treatment recommendations rapidly changing. Rapid response telephone triage and advice services are critical in providing timely care during pandemics. Understanding patient participation with triage recommendations and factors associated with patient participation can assist in developing sensitive and timely interventions for receiving the treatment to prevent adverse health effects of COVID-19. METHODS: This cohort study aimed to assess patient participation (percentage of patients who followed nursing triage suggestions from the COVID hotline) and identify factors associated with patient participation in four quarterly electronic health records from March 2020 to March 2021 (Phase 1: 14 March 2020-6 June 2020; Phase 2: 17 June 2020-16 September 2020; Phase 3: 17 September 2020-16 December 2020; Phase 4: 17 December 2020-16 March 2021). All callers who provided their symptoms (including asymptomatic with exposure to COVID) and received nursing triage were included in the study. Factors associated with patient participation were identified using multivariable logistic regression analyses, including demographic variables, comorbidity variables, health behaviors, and COVID-19-related symptoms. RESULTS: The aggregated data included 9849 encounters/calls from 9021 unique participants. Results indicated: (1) 72.5% of patient participation rate; (2) participants advised to seek emergency department care had the lowest patient participation rate (43.4%); (3) patient participation was associated with older age, a lower comorbidity index, a lack of unexplained muscle aches, and respiratory symptoms. The absence of respiratory symptoms was the only factor significantly associated with patient participation in all four phases (OR = 0.75, 0.60, 0.64, 0.52, respectively). Older age was associated with higher patient participation in three out of four phases (OR = 1.01-1.02), and a lower Charlson comorbidity index was associated with higher patient participation in phase 3 and phase 4 (OR = 0.83, 0.88). CONCLUSION: Public participation in nursing triage during the COVID pandemic requires attention. This study supports using a nurse-led telehealth intervention and reveals crucial factors associated with patient participation. It highlighted the importance of timely follow-up in high-risk groups and the benefit of a telehealth intervention led by nurses serving as healthcare navigators during the COVID-19 pandemic.

We aimed to investigate the number and prevalence of patients indicated for intravenous iron treatment in a large Korean population using criteria based on laboratory test results in an effort to extract indirect information on the need for intravenous iron treatment. Between 1 January 2019 and 31 December 2021, a total of 83,994 Korean patients (30,499 men and 53,495 women) with a median age of 46 years (interquartile range, 30-61) were evaluated using iron deficiency anemia-associated laboratory tests and serum creatinine tests of estimated glomerular filtration rates. The overall prevalence of anemia (Hb ≤ 11 g/dL) was 16.5%, and the proportion of patients with possible chronic kidney disease who had an estimated glomerular filtration rate < 60 mL/min/1.73 m2 was 11.4%. The number of patients indicated for reimbursable intravenous iron treatment was higher in women than in men, higher in older patients, and higher in 2021 than in 2019 (all p < 0.001). The prevalence of patients indicated for reimbursable intravenous iron treatment was up to 30.0% in those ≥ 80 years of age in 2019. The results of this study provide basic knowledge about the use of iron deficiency anemia-associated laboratory tests in planning nutritional support programs using an intravenous iron formulation in Korea.

PURPOSE: This study investigated correlations between the actual sleep time 24 hours prior to an examination and the time to achieve chloral hydrate sedation in pediatric patients. METHODS: With parental consent, 84 children who were placed under moderate or deep sedation with chloral hydrate for examinations from November 19, 2020 to July 9, 2022 were recruited. RESULTS: Patients' average age was 19.9 months. Pediatric neurology patients and those who underwent electroencephalography took significantly longer to achieve sedation with chloral hydrate. There was a negative correlation between the time to achieve sedation and actual sleep time within 24 hours prior to the examination. Positive correlations were found between the actual sleep time 24 hours prior to the examination and the second dose per weight, as well as between the sedation recovery time and awake hours before the examination. CONCLUSION: Sleep restriction is not an effective adjuvant therapy for chloral hydrate sedation in children, and sedation effects vary according to pediatric patients' characteristics. Therefore, it would be possible to reduce the unnecessary efforts of caregivers who restrict children's sleep for examinations. It is more important to educate parents about safe sedation than about sleep restriction.
RESUMO
Background and Objectives: This study aimed to evaluate the utility and accuracy of dual-energy automatic plaque removal (DE-APR) in patients with symptomatic peripheral arterial disease (PAD) using digital subtraction angiography (DSA) as the reference standard. Materials and Methods: We retrospectively analyzed 100 patients with PAD who underwent DE computed tomography angiography (DE-CTA) and DSA of the lower extremities. DE-CTA was used to generate APR subtracted images. In the three main arterial segments (aorto-iliac segment, femoro-popliteal segment, and below-the-knee segment), the presence or absence of hemodynamically significant stenosis (>50%) and calcification was assessed using the images. CTA data were analyzed using different imaging approaches (DE-standard reconstruction image (DE-SR), DE-APR maximum intensity projection image (APR), and DE-SR with APR). Results: For all segments evaluated, the sensitivity, specificity, and accuracy for detecting significant stenosis were 98.16%, 81.01%, and 89.58%, respectively, with DE-SR; 97.79%, 83.33%, and 90.56%, respectively, with APR; and 98.16%, 92.25%, and 95.20%, respectively, with DE-SR with APR. DE-SR with APR had greater accuracy than DE-SR or APR alone (p < 0.001 and p < 0.001, respectively). When analyzed based on vascular wall calcification, the accuracy of DE-SR with APR remained greater than 90% regardless of calcification severity, whereas DE-SR showed a considerable reduction in accuracy in moderate to severe calcification. In the case of APR, the degree of vascular wall calcification did not significantly influence the accuracy in the aorto-iliac and femoro-popliteal segments. DE-SR with APR achieved significantly higher diagnostic accuracy for all lower extremity segments in evaluating hemodynamically significant stenosis in patients with symptomatic PAD and transcended the impact of vascular wall calcification compared with DE-SR. Conclusions: APR demonstrated favorable diagnostic performance in the aorto-iliac and femoro-popliteal segments, exhibiting good agreement with DSA even in cases of moderate to severe vascular wall calcification.

Current guidelines on atrial fibrillation (AF) emphasized that radiofrequency catheter ablation (RFCA) should be decided after fully considering its prognosis. However, a robust prediction model reflecting the complex interactions between the features affecting prognosis remains to be developed. In this paper, we propose a deep learning model for predicting the late recurrence after RFCA in patients with AF. Aiming to predict the late recurrence (LR) of AF within 1 year after pulmonary vein isolation, we designed a multimodal model based on the multilayer perceptron architecture. For quantitative evaluation, we conducted 4-fold cross-validation on data from 177 AF patients including 47 LR patients. The proposed model (area under the receiver operating characteristic curve-AUROC, 0.766) outperformed the acute patient physiologic and laboratory evaluation (APPLE) score (AUROC, 0.605), CHA2DS2-VASc score (AUROC, 0.595), linear regression (AUROC, 0.541), logistic regression (AUROC, 0.546), extreme gradient boosting (AUROC, 0.608), and support vector machine (AUROC, 0.638). The proposed model exhibited better performance than clinical indicators (APPLE and CHA2DS2-VASc score) and machine learning techniques (linear regression, logistic regression, extreme gradient boosting, and support vector machine). The model will support clinical decision-making for selecting good responders to the RFCA intervention.

Mental healthcare disparities are routinely documented, yet they remain wider than in most other areas of healthcare services and common mental disorders (depression and anxiety) continue to be one of the highest health burdens for older people of color. To address disparities in mental health services for older people of color, the narrative must move beyond simply documenting these inequities and attain a better understanding of the internalized, interpersonal, systemic, and medical racism that have harmed these communities and excluded them from its services in the first place. It is imperative that researchers, clinicians, and policymakers acknowledge the realities of racism and discrimination as leading causes of mental healthcare disparities. Therefore, this review is a call-to-action. Authors adopt an antiracist and health equity lens in evaluating the differing needs of Blacks/African-Americans, Asian Americans, and Latinos by exploring psychiatric comorbidity, experiences with seeking, accessing, and engaging in treatment, and the unique cultural and psychosocial factors that affect treatment outcomes for these diverse groups. Further, authors offer researchers and practitioners tangible tools for developing and implementing culturally-sensitive, mental health focused interventions for older people of color with special attention placed on cultural adaptations, models of care, prevention, and practical strategies that can be implemented to reduce disparities and increase equity in mental healthcare.

Using data from a nationally representative sample of community-dwelling older adults (age ≥ 65) (NHANES: n = 3,114), we examined the association between the variety in sources of emotional support and thoughts of death or self-harm in the past two weeks among US older adults and if such association is modified by gender and race/ethnicity. Overall, an additional category of source of emotional support was associated with the 0.36-fold lower odds of endorsing thoughts of death or self-harm in the past two weeks (WAOR: 0.64, 95% CI: 0.46-0.89), after controlling for demographic, socioeconomic, and health-related characteristics. The magnitudes of such association varied across different gender and racial/ethnic subgroups. While among older women and non-Hispanic Black older men, increase in the variety of sources of emotional support was associated with decrease in the odds of endorsing thoughts of death or self-harm in the past two weeks, for non-Hispanic White older men and Hispanic older men, increase in the variety of sources of emotional support was associated with increase in the odds of endorsing thoughts of death or self-harm in the past two weeks. Our findings highlight the importance of considering gender and race/ethnicity when designing and implementing successful interventions for reducing suicide ideation among diverse elderly persons.

BACKGROUND: We aimed to investigate serum folate level in Korean women of reproductive age and to evaluate the prevalence of folate deficiency by age using different cutoffs. METHODS: We retrospectively reviewed data obtained with a serum folate assay traceable to World Health Organization international standard reference material 03/178. RESULTS: Between September 2017 and June 2019, data from a total of 8,380 Korean women aged 15 - 49 years were obtained. Mean (standard deviation) serum folate concentration for all women was 9.1 (6.7) ng/mL. Prevalence of folate deficiency using the cutoff of < 3 ng/mL was 6.2% and that for < 4 ng/mL was 14.9%. The prevalence of folate deficiency was higher in women of younger age (15 to < 25 years, even > 30% using the cutoff of 4 ng/mL) compared to other age groups. CONCLUSIONS: This study suggests that women aged 15 to < 25 years are at high risk of folate deficiency.

BACKGROUND: Limited data are available for validation of low-density lipoprotein cholesterol (LDL) calculation (LDLcal) in the adult Korean population. The aim of this study was to develop and validate a new equation for LDLcal and to compare it with previous such equations in a Korean population. METHODS: A new equation for LDLcal was developed (LDLChoi). LDLChoi and 11 other previously published equations were applied and compared with directly measured LDL concentration (LDLdirect) in a development cohort (population 1), an independent validation cohort in the same laboratory (population 2), and the Korea National Health and Nutrition Examination Survey 2017 cohort (population 3). RESULTS: Among the 12 equations, the newly-developed equation (LDLChoi = total cholesterol - 0.87 x high-density lipoprotein cholesterol - 0.13 x triglycerides) had the highest intraclass correlation coefficient (ICC) and the lowest mean systemic difference and median absolute percentage error in populations 1 and 2 but not in population 3. Subgroup analysis showed good agreement between LDLChoi and LDLdirect (ICC > 0.75) in population 2, whose LDLdirect < 70 mg/dL. For samples with high triglycerides (> 400 mg/dL), equation accuracy varied. Categorization concordance according to the National Cholesterol Education Program Adult Treatment Panel III criteria with the other 11 equations were less than 80%; that of LDLChoi was 87.6 and 87.4% in populations 1 and 2, respectively. CONCLUSIONS: Accuracy of 12 equations for LDLcal varied by cohort and subgroup based on LDLdirect and triglycerides. A laboratory-specific equation for LDLcal and/or LDLdirect may be needed for accurate evaluation of LDL status.

We developed a novel approximate Bayesian computation (ABC) framework, ABCDP, which produces differentially private (DP) and approximate posterior samples. Our framework takes advantage of the sparse vector technique (SVT), widely studied in the differential privacy literature. SVT incurs the privacy cost only when a condition (whether a quantity of interest is above/below a threshold) is met. If the condition is sparsely met during the repeated queries, SVT can drastically reduce the cumulative privacy loss, unlike the usual case where every query incurs the privacy loss. In ABC, the quantity of interest is the distance between observed and simulated data, and only when the distance is below a threshold can we take the corresponding prior sample as a posterior sample. Hence, applying SVT to ABC is an organic way to transform an ABC algorithm to a privacy-preserving variant with minimal modification, but yields the posterior samples with a high privacy level. We theoretically analyzed the interplay between the noise added for privacy and the accuracy of the posterior samples. We apply ABCDP to several data simulators and show the efficacy of the proposed framework.
RESUMO
BACKGROUND: We aimed to investigate the associations between glycemic biomarkers (hemoglobin A1c [HbA1c], fructosamine, and glycated albumin [GA]) in Korean adults. METHODS: We retrospectively reviewed data for HbA1c, fructosamine, and glycated albumin between August 28, 2017, and June 30, 2020, to investigate the association between HbA1c and fructosamine and between HbA1c and GA. RESULTS: Overall, 961 fructosamine and 142 GA tests concurrently measured HbA1c. The equations were HbA1c (%) = 0.0175 x fructosamine (µmol/L) + 1.6255 and HbA1c (%) = 0.2029 x GA + 2.8102, respectively. The absolute difference between estimated and measured HbA1c ranged from -3.4% to 2.1% HbA1c with the fructosamine equation and -3.2% to 2.8% HbA1c with the GA equation. CONCLUSIONS: Fructosamine and GA may be useful adjuncts to HbA1c in Korean patients.

BACKGROUND: Little is known about the reference interval of serum folate concentration if using recently re-standardized assays traceable to the World Health Organization (WHO) international standard reference 03/178 in a Korean population. This study aimed to investigate serum folate levels in Korean subjects without macrocytic anemia or increased homocysteine, for the assessment of folate deficiency. METHODS: We retrospectively reviewed data from Korean adults whose hemoglobin, mean corpuscular volume, and serum total homocysteine values were within reference limits. RESULTS: The median (interquartile range) serum folate level was 7.8 (5.4 - 12.6) ng/mL in men and 10.2 (6.9 - 15.6) ng/mL in women. The reference interval for serum folate (2.5th and 97.5th percentiles) ranged from 2.9 to 38.0 ng/ mL. From among 723 Korean adults, the lower limit of reference intervals of serum folate for folate deficiency, defined as the 2.5th percentile, was 2.9 ng/mL. The prevalence of folate deficiency was higher in men (6.5%) than in women (1.2%, p < 0.05) when a cutoff value of 3.0 ng/mL was applied. Using the cutoff value of 4 ng/mL for folate deficiency, which is in accordance with the instructions from the manufacturer of the new assay and the WHO 2012 guideline for homocysteine as a metabolic indicator before assay standardization, about 5% of subjects were reclassified as folate deficient. CONCLUSIONS: Our study suggests that any change of reference limits using a re-standardized assay needs to be verified in clinical laboratories.

Background: Proper nutrition is an essential component to both physical and emotional health. Food insecurity (FI) is a potentially critical public health problem. The link between FI and elevated risk for depression has been well documented. Yet, it is largely unknown how diverse older adult populations experience FI differently. Therefore, the aims of this study were to examine how gender, race/ethnicity, and nativity may impact the magnitude of the association between FI and depression. Methods: We used a nationally representative sample of the Asian American population from the National Latino and Asian American Study (NLAAS). We built logistic regression models with major depression in the past 12 months as the dependent variable, and FI as the independent variable. Several demographic and socioeconomic characteristics were added to the models to control for potential biases. All statistical estimates were weighted, using the recommended NLAAS sampling weight, to ensure representativeness of the US population. Results: About 35% (weighted adjusted 95% CI: 29.49-39.00) of Asian Americans experienced some level of FI at the time of survey. Experiencing FI over the past 12 months increased the likelihood of having clinical depression (weighted adjusted odds ratio: 1.44, weight adjusted confidence interval: 0.79-2.10). The magnitude of associations between FI and depression varied by race/ethnicity (F (7, 47) = 6.53, p (3, 41) = 10.56, p (3, 41) = 9.85). Conclusions: Food insecurity significantly increases the likelihood of clinical depression among Asian Americans. Greater attention is needed towards food-insecure Asian Americans and their mental health.
RESUMO
Purpose: Pain and mood disorder frequently coexist. Yet, for Asian Americans (AAs), scant information about pain and mood disorder is available. Our aims were to compare (1) the rates of pain and mood disorders and (2) the magnitude of associations between pain and mood disorders between AAs and European Americans (EAs), and across different Asian subgroups. Methods: An analytical data was constructed from the Collaborative Psychiatric Epidemiology Studies (CPES), a representative sample of community-residing U.S. adults (n = 9,871). Pain morbidity was assessed by self-report. Mood disorders, including major depression and anxiety disorders, were assessed using the diagnostic interview. Analysis included descriptive statistics and multivariate logistic regression modeling. All analyses were weighted to approximate the U.S. populations, and controlled for sociodemographic and immigration characteristics. Results: Greater proportion of EAs, compared to AAs, endorsed lifetime pain (56.8% vs. 35.8%). Having life pain disorders elevated the likelihood of lifetime mood disorder by more than 2-folds (weight adjusted odds ratio (WAOR): 2.12, 95% CI: 1.77, 2.55). Having pain disorders over the past 12 months elevated the likelihood of mood disorder in the same time period by more than 3-folds (WAOR: 3.29, 95% CI: 2.02, 5.37) among AAs. The magnitude of the association between pain and psychiatric morbidity were greater in Vietnamese Americans compared to other AAs and EAs. Discussion: The conventional belief that rates of pain and mood disorders are greater in AAs than EAs may need to be further examined. Vietnamese Americans may be particularly vulnerable for experience of comorbid pain and mood disorders.
RESUMO
The purpose of this paper is to provide a brief summary of mental health issues among Asian and Pacific Islander (API) communities in the U.S. APIs include individuals from Far East Asia (e.g., Korea, China), Central Asia (e.g., Afghanistan, Uzbekistan), South Asia (e.g., India, Pakistan), South East Asia (e.g., Thailand, Philippines), Western Asia (e.g., Iran, Saudi Arabia), and Pacific islands (e.g., Hawaii, Samoa, Mariana island, Fiji, Palau, French Polynesia, Marshall Islands, Micronesia, New Zealand, Tokelau islands, Niue, and Cook Islands). Collectively they speak more than one hundred languages and dialects. Such a diversity across the API community presents unique challenges and opportunities for research, education, and practice. The existing body of literature on mental health issues in API communities is marred by the lack of high-quality data and insufficient degrees of disaggregation. Such a knowledge gap hindered our ability to develop culturally and linguistically tailored interventions, and in turn, API communities have experienced mental health disparities and mental health services' disparities. To move the field forward, future research effort with APIs should focus on articulating variations across different API subgroups, identifying what explains such variations, and examining the implications of such variations to research, practice, education, and policy.
RESUMO
BACKGROUND: Current guidelines pertaining to diagnosing macrocytic anemia in association with vitamin B12 and folate deficiency recommend that vitamin B12, folate, homocysteine, and methylmalonic acid assays should be assessed concurrently due to their close relationship in metabolism. We aimed to investigate the completion of these assays in local clinics and hospitals without in-house clinical laboratories in Korea. METHODS: We retrospectively reviewed data from the laboratory information system between September 25, 2017, and June 30, 2019, to investigate usage rates of vitamin B12, folate, homocysteine, and methylmalonic acid assays in patients with macrocytic anemia. RESULTS: During the study period, 14 894 Korean adults among 109 524 (13.6%) total hemoglobin-tested subjects underwent concurrent erythrocyte mean corpuscular volume (MCV) tests. Among these 14,894 adults, 265 (1.2%) from 94 local clinics or hospitals without in-house clinical laboratories in Korea had macrocytic anemia. Furthermore, among these 265 adults, only one woman underwent serum vitamin B12 and folate assay and one man underwent serum homocysteine testing during the study period. No patients among the 265 individuals with macrocytic anemia received erythrocyte folate or methylmalonic acid testing (with either serum, plasma, random urine, or 24-hour collected urine). CONCLUSIONS: The results of this study provide basic information regarding utilization rates of assays in association with vitamin B12 and folate deficiency. Making more data available is expected to improve rates of testing in patients with macrocytic anemia in local clinics and hospitals without in-house clinical laboratories in Korea.

BACKGROUND: We retrospectively investigated soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratios and screen-positive rates according to cutoff values for preeclampsia risk assessment based on the number of fetuses. METHODS: sFlt-1/PlGF ratios < 38.0 and < 53.0 were defined as low risk of preeclampsia (screen negative) for singleton and twin pregnancies, respectively. RESULTS: During the study period, 442 test results from 403 pregnant women (374 with singleton and 29 twin pregnancies) from 32 local clinics and hospitals were analyzed. The overall rate of positive preeclampsia screening was 25.1% and this rate was higher when gestational age was ≥ 34 weeks than when it was < 34 weeks (58.7% vs. 18.6%, p < 0.05). Among 34 women with follow-up results, a change in interpretation category was observed during the follow-up period at ≥ 4.8 weeks for singleton and ≥ 1.6 weeks for twin pregnancies, respectively. CONCLUSIONS: This study may help to understand the sFlt-1/PlGF ratio in pregnant Korean women.

OBJECTIVE: To compare outcomes associated with patient education about glycemic control via group chat versus patient education as usual among individuals with diabetes in China. METHODS: We searched the following databases both in English and in Chinese languages: PubMed, CNKI, Wanfang database, VIP database, and CBM for articles published up to Jan 1, 2018. The studies were screened by two independent reviewers. Using criteria from the risk of bias assessment tool developed by Cochrane Collaboration to assess the risk of bias of eligible studies. A meta-analysis of studies was performed using comprehensive meta-analysis version 3.0. RESULTS: Twenty-five unique randomized clinical trials, including 2,838 patients, were identified. The education delivered via group chat had large overall pooled effect sizes in improving glucose control measured by hemoglobin A1c [Hedges' g = -0.81, 95% CI: (-0.98, -0.64)], fasting blood glucose [Hedges' g = -1.11, 95% CI: (-1.37, -0.85)], and 2 h postprandial blood glucose [Hedges' g = -0.98, 95% CI: (-1.20, -0.76)]. Additionally, patient education delivered via group chat has shown consistently superior outcomes in glucose control in short-term (0-3 months), mid-term (3-6 months) and longer-term (6-12 months). CONCLUSIONS: Educational interventions via group chat had a superior outcome in blood glucose control compared to education as usual in China. Educational interventions via group chat had superior short-term, mid-term, and longer-term outcomes in blood glucose control compared to education as usual in China.
