Abstract
OBJECTIVES
This study investigated the effectiveness of early medication treatment and metformin use for cancer prevention in type 2 diabetes patients.
METHODS
Population-based cohort data were used from the Korean National Health Insurance Service-National Sample Cohort database (KNHIS-NSC) for 2002-2013. Patient-specific medication prescription status was defined by the landmark time (LMT; a fixed time after cohort entry), considering both pre- and post-LMT prescriptions to control methodological biases in observational research. The LMT was set to 2 years. Logistic regression analysis with multivariable adjustment was conducted to analyze cancer incidence by patient-specific medication prescription status.
RESULTS
Only 33.4% of the subjects were prescribed medication early (before the LMT) with compliance. Cancer incidence in individuals with early prescription and compliance was 25% lower (odds ratio [OR], 0.75; 95% confidence interval [CI], 0.67 to 0.84) than in those without. As early-prescribed medications, metformin monotherapy and metformin combination therapy were associated with 34% (OR, 0.66; 95% CI, 0.51 to 0.83) and 25% (OR, 0.75; 95% CI, 0.64 to 0.88) lower cancer risk than non-use, respectively. Patients who were prescribed late (post-LMT) but did not comply with the prescription had a 24% (OR, 1.24; 95% CI, 0.97 to 1.58) higher cancer incidence than non-users. Among patients who started monotherapy early without changes throughout the entire follow-up period, those who started on metformin had a 37% (OR, 0.63; 95% CI, 0.41 to 0.99) lower risk of cancer than non-metformin users.
CONCLUSIONS
Doctors must prescribe antidiabetic medication early, and patient compliance is required, regardless of the prescription time, to prevent cancer. Metformin monotherapy or combination therapy is recommended as an early prescription.
Summary
Korean summary
당뇨 환자는 암 발병 위험이 높으며 암은 주요 사망 원인이다. 당뇨환자의 암발생 예방을 위한 관리로서, 당뇨병 진단 후 약물 치료 시기에 대한 연구는 부족하다. 또한, 전 세계적으로 가장 흔히 처방되는 당뇨병 치료제인 메트포민은 암 예방 효과가 있다고 알려져 왔으나 관측연구에서 발생하는 선택 편향의 문제가 제기되었고, 최근 일부 연구에서 기존의 암 예방 효과와 상충되는 결과가 나오고 있어 논쟁이 이어지고 있다. 본 연구는 선택 편향을 통제한 코호트 연구에서 조기 약물 치료와 메트포민 사용이 당뇨환자의 암 예방에 효과적임을 밝혔다. 따라서 의사들은 처음 당뇨 진단을 받은 환자에게 조기에 약물 처방을 하고, 환자들은 처방에 잘 따라야 한다. 조기 처방 약물로서 메트포민이 권장된다.
Key Message
Diabetic patients have a high risk of developing cancer, and cancer is the leading cause of death. There are few studies on the timing of medication treatment after diagnosis of diabetes. In addition, metformin, the most commonly prescribed diabetes treatment worldwide, is known to have cancer-preventive effects, but the problem of selection bias that occurs in observational studies has been raised, and some studies have recently been contradicting the existing cancer-preventing effects of metformin. This study, in a cohort study controlled for selection bias, demonstrated that early medication treatment and metformin use were effective in preventing cancer in diabetic patients.

Abstract
Research based on spatiotemporal analysis has been conducted to identify various factors that can affect an individual’s or community’s degree of health and disease. These spatiotemporal studies can effectively illustrate patterns in disease frequency, features, and temporal flow in different parts of a country. Furthermore, identifying these regional characteristics can aid in the development of disease prevention or intervention strategies.

Abstract
OBJECTIVES
Despite growing concerns regarding the timing of eating, little is known about the association between late eating and health. This study aimed to investigate whether late eating is associated with blood pressure (BP) control and cardiometabolic risk factors among Korean adults with hypertension.
METHODS
Data from the Korea National Health and Nutrition Examination Survey 2010-2018 were used. Adults with hypertension aged 30-79 years (n=13,361) were included in this study. Dietary intake and information on meal timing were assessed using 1-day 24-hour recall. Late eating was defined as after the median midpoint between the times of the first and the last eating episode during the recall day. Logistic and linear regression models were used to estimate the associations of late eating with BP control and cardiometabolic risk factors.
RESULTS
Among late eaters, there were more men than women. Compared to early eaters, late eaters were younger, had a higher body mass index (BMI) and unhealthier habits, and their overall dietary quality score was lower. A negative association between late eating and BP control was found in a univariate model (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.94 to 1.12), but this association disappeared after adjustment for confounders (OR, 1.03; 95% CI, 0.94 to 1.12). Late eating was independently associated with higher BMI (p=0.03) and blood triglyceride concentration (p<0.01).
CONCLUSIONS
Our results do not support a link between late eating and BP control among adults with hypertension, but suggest that late eating is associated with cardiometabolic risk factors.

식사시간이 건강에 미치는 영향에 대한 관심이 증가하고 있지만, 이에 대한 근거는 많지 않다. 이 연구는 국민건강영양조사 자료를 활용하여 고혈압이 있는 성인의 늦은 식사와 혈압 조절, 심장대사 위험인자의 연관성을 분석하였다. 늦은 식사와 혈압 조절의 독립적 연관성은 찾지 못했지만, 늦은 식사는 높은 체질량지수, 혈중 지질 농도와 연관성을 보여 식사 시간 조정이 고혈압 환자의 예후 개선을 위한 유용한 대책이 될 수 있으리라는 근거를 지지한다.
Key Message
This study investigated whether late eating is associated with blood pressure (BP) control and cardiometabolic risk factors among Korean adults with hypertension using data from the Korea National Health and Nutrition Examination Survey 2010–2018. We did not find an independent association between late eating and BP control among Korean adults with hypertension, but found that late eating was significantly associated with higher BMI and a higher blood concentration of triglycerides, independent of potential confounders. Our findings support the suggestion that a time-based dietary approach can be used as a useful strategy to improve the prognosis of adults with hypertension.

Abstract
OBJECTIVES
This study was conducted to examine gender differences in under-reporting hiring discrimination by building a prediction model for workers who responded “not applicable (NA)” to a question about hiring discrimination despite being eligible to answer.
METHODS
Using data from 3,576 wage workers in the seventh wave (2004) of the Korea Labor and Income Panel Study, we trained and tested 9 machine learning algorithms using “yes” or “no” responses regarding the lifetime experience of hiring discrimination. We then applied the best-performing model to estimate the prevalence of experiencing hiring discrimination among those who answered “NA.” Under-reporting of hiring discrimination was calculated by comparing the prevalence of hiring discrimination between the “yes” or “no” group and the “NA” group.
RESULTS
Based on the predictions from the random forest model, we found that 58.8% of the “NA” group were predicted to have experienced hiring discrimination, while 19.7% of the “yes” or “no” group reported hiring discrimination. Among the “NA” group, the predicted prevalence of hiring discrimination for men and women was 45.3% and 84.8%, respectively.
CONCLUSIONS
This study introduces a methodological strategy for epidemiologic studies to address the under-reporting of discrimination by applying machine learning algorithms.

Abstract
OBJECTIVES
This study examined the spatiotemporal epidemiological status of diabetes-related death in relation to school district boundaries in the state of Michigan, United States.
METHODS
A retrospective observational study was conducted using death records spanning the years 2007-2014 in Michigan, with school districts as the geographic unit of analysis. Geocoding was performed for each death record. Cluster analysis used spatial autocorrelation with local Moran’s I, and spatiotemporal analysis used the Space Time Pattern Mining tool in ArcGIS Pro 2.1.
RESULTS
The study revealed spatial clusters of high-high locations of diabetes-related mortality rate by school district in Michigan from 2007 to 2014. Spatiotemporal analysis showed grids with intensifying, consecutive, sporadic, and persistent hotspots of diabetes-related death in the Lansing, Royal Oak, Flint City, Berkley, Detroit City, East Lansing, South Lake, and Holt public school districts. These school districts should be prioritized for school-based diabetes prevention programs
CONCLUSIONS
The study demonstrated the presence of various hotspots of diabetes-related deaths within the state of Michigan across the 8-year period of analysis. Understanding spatial and temporal hotspots could further improve our ability to evaluate diabetes burden across both time and space.
Summary
Korean summary
Key Message
Using existing secondary data with spatio-temporal analysis, the study identified diabetes-related death varies across space and time within the state of Michigan, USA at the school district level. This approach provided policy-relevant information to target high-risk school-district when having limited resources to prevent diabetes at schools.

Abstract
OBJECTIVES
The aim of this study was to evaluate the real-world incidence of endophthalmitis after intravitreal anti-vascular endothelial growth factor (VEGF) injections using data from the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM).
METHODS
Patients with endophthalmitis that developed within 6 weeks after intravitreal anti-VEGF injections were identified in 3 large OMOP CDM databases.
RESULTS
We identified 23,490 patients who received 128,123 intravitreal anti-VEGF injections. The incidence rates of endophthalmitis were 15.75 per 10,000 patients and 2.97 per 10,000 injections. The incidence rates of endophthalmitis for bevacizumab, ranibizumab, and aflibercept (per 10,000 injections) were 3.64, 1.39, and 0.76, respectively. The annual incidence has remained below 5.00 per 10,000 injections since 2011 despite the increasing number of intravitreal anti-VEGF injections. Bevacizumab presented a higher incidence rate for endophthalmitis than ranibizumab and aflibercept (incidence rate ratio, 3.17; p=0.021).
CONCLUSIONS
The incidence of endophthalmitis after intravitreal anti-VEGF injections has stabilized since 2011 despite the explosive increase in anti-VEGF injections. The off-label use of bevacizumab accounted for its disproportionately high incidence of endophthalmitis. The OMOP CDM, which includes off-label uses, laboratory data, and a scalable standardized database, could provide a novel strategy to reveal real-world evidence, especially in ophthalmology.

Abstract
OBJECTIVES
The study aimed to examine whether simultaneously meeting the combined guidelines of accelerometer-assessed moderate to vigorous physical activity (MVPA) and self-reported muscle-strengthening activity (MSA) was associated with lower odds of metabolic syndrome (MetS) than meeting neither or 1 of the guidelines among the Koreans.
METHODS
This cross-sectional analysis included 1,355 participants from the Korea National Health and Nutrition Examination Survey (2014-2015). Logistic regression was used to analyze the associations across groups of MVPA-MSA guideline adherence (meeting neither [reference]; meeting MVPA only; meeting MSA only; meeting both MVPS and MSA) with MetS components (abdominal obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol [HDL-C], hypertension, and hyperglycemia). The odds ratios (ORs) were adjusted for covariates (e.g., sex, age, body mass index, and accelerometer wearing time).
RESULTS
MSA only significantly reduced the OR for abdominal obesity (OR, 0.34; 95% confidence interval [CI], 0.13 to 0.91). Meeting both MVPA and MSA reduced the OR for hypertriglyceridemia (OR, 0.59; 95% CI, 0.39 to 0.88) and low HDL-C (OR, 0.46; 95% CI, 0.31 to 0.68). Compared to meeting neither, MVPA only (OR, 0.63; 95% CI, 0.44 to 0.89) and both MVPA and MSA (OR, 0.46; 95% CI, 0.28 to 0.76) significantly reduced the OR for MetS.
CONCLUSIONS
Combined MVPA-MSA was more beneficially associated with MetS prevalence than MVPA only and MSA only. Considering that more than 85% of Korean adults do not meet both the MVPA and MSA guidelines, public health actions to promote adherence should be supported.

Abstract
The contagiousness of coronavirus disease-2019 (COVID-19) led to the imposition of historical lockdowns in various countries. No scientific mind could have made accurate projections of the tremendous impact that COVID-19 would have on nations, communities, and the global-wide economy. Meanwhile, millions of workers have lost their jobs, while healthcare workers are overwhelmed and are reaching a state of mental and physical exhaustion. With the uncontrollable spread, researchers have been working to identify factors associated with COVID-19. In this regard, race, ethnicity, industry, and occupation have been found to be predominant factors of interest. However, unfortunately, the unavailability of such information has been a difficult reality. Since race, ethnicity, and employment are essential social determinants of health and could serve as potential risk-factors for COVID-19, collecting such information may offer important context for prioritising vulnerable groups. Thus, this perspective aims to highlight the importance and need for collecting race, ethnicity, and occupation-related data to track and treat the racial/ethnic groups that have been most strongly affected by the COVID-19 pandemic. Collecting such data will provide valuable insights and help public health officials recognise workplace-related outbreaks and evaluate the odds of various ethnic groups and professions contracting COVID-19.

Abstract
OBJECTIVES
Data are not available in Indonesia to measure the main indicators of zero new infections, zero acquired immune deficiency syndrome (AIDS)-related deaths and zero discrimination. This study aimed to determine factors related to misconceptions about human immunodeficiency virus (HIV) transmission and the stigma against people living with HIV/AIDS (PLWHA) in Indonesia
METHODS
This cross-sectional study used secondary data from the 2017 Indonesia Demographic and Health Survey (IDHS). The sample was women and men aged 17-45 years and married (n=3,023).
RESULTS
Education and wealth index quintile were significantly related to misconceptions about HIV transmission. Respondents with low levels of education were more likely to have misconceptions about HIV transmission. Respondents who were in the poorest, poorer, middle, and richer quintiles of the wealth index were more likely to have misconceptions about HIV transmission than those in the richest quintile. Educational level, employment status, and wealth index quintile were predictors of stigma against PLWHA.
CONCLUSIONS
There are still many Indonesian people with misconceptions about HIV transmission and stigma against PLWHA. Future studies should focus on educational programs or interventions aimed at increasing public knowledge and awareness, promoting compassion towards PLWHA, and emphasizing respect for the rights of PLWHA. These interventions are particularly important for populations who are uneducated and living in poverty.

Abstract
OBJECTIVES
We investigated the risk of chemotherapy-related and radiotherapy-related cognitive impairment in colorectal cancer patients.
METHODS
Medical use data of colorectal cancer patients were obtained from the Korean National Health Insurance Database from 2004 to 2018. We randomly selected 40% of all colorectal cancer patients (n=148,848). Cognitive impairment was defined as having 1 or more International Classification of Diseases, 10th revision diagnostic codes for dementia or mild cognitive impairment. Patients aged 18 years or younger, patients diagnosed with cognitive impairment before colorectal cancer diagnosis (n=8,225), and patients who did not receive primary resection (n=45,320) were excluded. The effects of individual chemotherapy regimens on cognitive impairment were estimated. We additionally estimated the effect of radiotherapy in rectal cancer patients. Time-dependent competing risk Cox regression was conducted to estimate the overall and age-specific hazard ratios (HR) separately for colon and rectal cancer. Landmark analyses with different lag times were conducted as sensitivity analyses.
RESULTS
Chemotherapy did not increase the risk of cognitive impairment in colorectal cancer patients (colon cancer: HR, 0.92; 95% confidence interval [CI], 0.83 to 1.03; rectal cancer: HR, 0.88; 95% CI, 0.75 to 1.04), while radiotherapy was negatively associated with cognitive impairment in rectal cancer patients (HR, 0.01; 95% CI, 0.84 to 0.99). Varying directions of the associations between regimens and cognitive impairment were detected. The adverse effect of certain chemotherapy regimens on cognition was more prominent in older adults.
CONCLUSIONS
Chemotherapy and radiotherapy did not increase the risk of cognitive impairment. Older patients with low cognitive reserve could be affected by the adverse cognitive effects of chemotherapy.

Abstract
OBJECTIVES
The relationship between receiving early antenatal care (ANC) and 8 or more antenatal contacts (ANC8+) has not been well characterised across low-and middle-income countries (LMICs). It is also unclear whether the association between early ANC and ANC8+ is modified by a woman’s place of residence. Our primary aim was to assess the relationship between early ANC and ANC8+ and to investigate whether this relationship was modified by place of residence. We also estimated the coverage of ANC8+ across LMICs.
METHODS
We analysed data on 207,388 mothers with a recent live birth using multiple indicator cluster surveys conducted between 2017 and 2020 in 30 LMICS. Modified Poisson regression with robust variance was used to evaluate the relationship between early ANC and ANC8+, whilst adjusting for country, clustering, stratification, and sampling weights. Effect modification by place of residence was assessed on additive and multiplicative scales. A meta-analysis was conducted to pool prevalence estimates of ANC8+ across all countries.
RESULTS
The overall prevalence of ANC8+ was 35.6%, ranging from 1.7% in Madagascar to 99.4% in Belarus. Early ANC was positively associated with ANC8+ (adjusted prevalence ratio [aPR], 2.61; 95% confidence interval [CI], 1.82 to 3.74). There was evidence of positive effect modification on additive (relative excess risk due to interaction, 0.39; 95% CI, 0.35 to 0.44) and multiplicative (aPR, 1.78; 95% CI, 1.08 to 2.95) scales.
CONCLUSIONS
Many LMICs may not have adopted the 2016 World Health Organization guidelines on ANC8+. Receiving early ANC was associated with a higher likelihood of ANC8+, particularly for women in rural areas.
Summary
Korean summary
Key Message
Our findings suggest that early antenatal care (ANC) was associated with the likelihood of receiving eight or more ANC contacts (ANC8+) among all mothers across low-and middle-income countries. This association was modified by a woman’s place of residence such that mothers living in rural areas who received early ANC had a higher prevalence of ANC8+. Public health programs, which focus on increasing the coverage of ANC8+ should encourage all pregnant women to receive early ANC, particularly those living rural areas.

Abstract
OBJECTIVES
We aimed to determine the characteristics of the deceased victims of deaths caused by exposure to humidifier disinfectants, and present the distribution of the victims’ data submitted for damage application, demographic characteristics, imaging findings, characteristics of humidifier disinfectant exposure, and distribution of the causes of death.
METHODS
An integrated database of victims was established using the medical records data of 1,413 victims submitted during the application for death damage caused by exposure to humidifier disinfectants, and the demographic characteristics, medical records, imaging findings, exposure characteristics, and cause of death were examined.
RESULTS
The average numbers of data submissions of each applicant for death damage were 3.0 medical use records. A total of 608 (43.0%) victims had more than one finding of acute, subacute, or chronic interstitial lung diseases. The average daily and cumulative use times of the victims were 14.40 and 24,645.81 hours, respectively, indicating greater exposure in this group than in the survivors. The humidifier disinfectants’ components comprised polyhexamethylene guanidine (72.8%), chloromethylisothiazolinone/methylisothiazolinone (10.5%), other components (15.0%), and oligo-[2-(2-ethoxy)-ethoxyethyl] guanidine chloride (1.5%). The components’ distribution was 67.8% for single-component use, which was higher than that in the survivors (59.8%). The distribution of the causes of death were: respiratory diseases (54.4%), neoplasms (16.8%), and circulatory diseases (6.3%). Other interstitial lung diseases (65.5%) were the most common cause of death among those who died due to respiratory diseases.
CONCLUSIONS
Careful discussions of appropriate remedies should be conducted based on a comprehensive understanding of the characteristics of the deceased victims, considering their specificities and limitations.

Abstract
OBJECTIVES
Diabetes self-management education (DSME) programs are a strategy to maintain healthy behaviors. Nevertheless, limited evidence has been reported from systematic evaluations of the effects of DSME integrated with peer support on glycemic control. This study aimed to review the effectiveness of DSME interventions integrated with peer support on glycemic control in patients with type 2 diabetes.
METHODS
A systematic search was carried out in electronic databases, including PubMed, Cochrane Library, ProQuest, SpringerLink, ScienceDirect, Scopus, and Google Scholar, for English-language articles published from 2005 until 2020. The effect size was estimated as the standard mean difference (SMD). The Cochrane Collaboration’s Risk of Bias tool was employed to assess the risk of bias.
RESULTS
Twelve studies were included in this study. DSME integrated with peer support effectively reduced glycated hemoglobin A1c (HbA1c) levels, with a statistically significant effect (SMD, -0.41; 95% confidence interval [CI], -0.69 to -0.13; p<0.001). Programs with a sample size <100 (SMD, -0.45; 95% CI, -0.79 to -0.11; p=0.009), duration of intervention ≤6 months (SMD, -0.52; 95% CI, -0.96 to -0.07; p=0.020), baseline HbA1c <8.5% (SMD, -0.42; 95% CI, -0.77 to -0.07; p=0.020), delivery by group (SMD, -0.28; 95% CI, -0.51 to -0.06; p=0.010), and high frequency of contact (SMD, -0.29; 95% CI, -0.48 to -0.10; p=0.003) had statistically significant effects on reducing HbA1c levels in patients with type 2 diabetes.
CONCLUSIONS
DSME integrated with peer support effectively enhances glycemic control in patients with type 2 diabetes. Programs with smaller participants groups, shorter interventions, weekly meetings, and closer group sessions improved glycemic control in patients with type 2 diabetes.
Summary
Korean summary
Key Message
We reviewed and assessed the quality of the twelve articles included in this systematic review and meta-analysis. The findings of this review show that peer support integrated with diabetes self-management education programs can significantly enhance glycemic control in type 2 diabetes patients. Peer support is a critical component of a successful diabetes self-management programme in patients with type 2 diabetes. interventions programme with smaller groups, shorter durations, lower HbA1c baseline levels, group sessions, and high frequencies of sessions significantly enhanced glycemic control.

Abstract
OBJECTIVES
To conduct a systematic review of coronavirus disease 2019 (COVID-19)-related biosafety guidelines for dental clinical practice in the early stage of the pandemic, focusing on quality assessment.
METHODS
Electronic (via PubMed, Scopus, Web of Science, Latin American and Caribbean Health Sciences Literature database, Brazilian Library in Dentistry, and Cochrane Library) and gray literature searches were performed for documents published up to May 12, 2020. Guidelines updated until April 17, 2021 were identified. Documents were included as guidelines if they (1) consisted of a set of statements, directions, or principles presenting current or future rules or policy; (2) were developed by government agencies, institutions, organizations, or expert panels; and (3) were related to the general conduct of healthcare activities rather a particular condition. Two researchers, using the Appraisal of Guidelines for Research & Evaluation II, independently extracted the recommendations and evaluated the quality of the guidelines.
RESULTS
Twenty-seven documents from 19 countries were included in the review. These documents presented 122 recommendations related to (1) professional biosafety; (2) patients’/companions’ safety; (3) the organization and biosafety of the physical dental facility environment; and (4) the work process in dental care. Overall, the scientific quality of the guidelines was considered low. Some recommendations presented in these guidelines would require further research to establish their effectiveness.
CONCLUSIONS
We found a wide variety of biosafety guidelines for dental practice regarding COVID-19 in the early months of the pandemic, but their quality was low. Biosafety recommendations should be frequently updated.
Summary
Korean summary
Key Message
Despite the wide variety of biosafety guidelines for dental practice regarding COVID-19 in the early months of the pandemic, their quality was low. These findings demonstrate the need for more guidelines for dental practice with more high-quality evidence, focusing on clarification of the strictness of development, financing, conflicts of interest, and applicability. Guidelines with high scientific quality are essential for the formation of a robust scientific consensus facilitating the ability to offer safer and more reliable procedures in the pandemic context.
