RESUMEN
The increasing prevalence of sleep dysregulation cases has prompted the search for effective and safe sleep-enhancing agents. Numerous medications used in the treatment of sleep disorders function by enhancing γ-aminobutyric acid neurotransmitter activity. Unfortunately, these substances may induce significant adverse effects in chronic users, such as dependence and motor behavior impairments. Consequently, there is a growing interest in exploring therapeutic sleep-enhancing agents derived from natural sources, with the anticipation of causing less severe side effects. Prunella vulgaris (PV), a perennial plant indigenous to South Korea, exhibits various pharmacological effects, likely attributed to its chemical composition. Rosmarinic acid, one of its components, has previously demonstrated sleep-potentiating properties, suggesting the potential for PV to exhibit similar pharmacological effects. This study aims to investigate the potential effects of repeated administration of PV extract on the sleep behavior, brainwave activity, sleep-wake cycle, and physiological behavior of mice. Findings indicate that PV extracts exhibit sleep-enhancing effects in mice, characterized by prolonged sleep duration and a reduced onset time of pentobarbital-induced sleep. However, PV extracts only reduced alpha wave powers, with minor alterations in wakefulness and rapid-eye-movement sleep duration. In contrast to diazepam, PV extracts lack adverse effects on locomotor activity, motor coordination, or anxiety in mice. Receptor-binding assay and caffeine treatment support the potential involvement of adenosine A2A receptors in the effects of PV, suggesting distinct mechanisms of action compared to diazepam, despite both exhibiting sleep-altering effects. Overall, our results suggest that PV holds promise as a potential source of sleep-aiding agents.
RESUMEN
The spread of American Bullfrog has a significant impact on the surrounding ecosystem. It is important to study the mechanisms of their spreading so that proper mitigation can be applied when needed. This study analyzes data from national surveys on bullfrog distribution. We divided the data into 25 regional clusters. To assess the spread within each cluster, we constructed temporal sequences of spatial distribution using the agglomerative clustering method. We employed Elementary Cellular Automata (ECA) to identify rules governing the changes in spatial patterns. Each cell in the ECA grid represents either the presence or absence of bullfrogs based on observations. For each cluster, we counted the number of presence location in the sequence to quantify spreading intensity. We used a Convolutional Neural Network (CNN) to learn the ECA rules and predict future spreading intensity by estimating the expected number of presence locations over 400 simulated generations. We incorporated environmental factors by obtaining habitat suitability maps using Maxent. We multiplied spreading intensity by habitat suitability to create an overall assessment of bullfrog invasion risk. We estimated the relative spreading assessment and classified it into four categories: rapidly spreading, slowly spreading, stable populations, and declining populations.

BACKGROUND: With an increase in the aging population, the number of older adults who require long-term care (LTC) is growing, enhancing drug-related issues. The reduced capacity of LTC users to precisely utilize medical services poses additional challenges owing to restrictions in daily activities. We compared older adults who required LTC with those who did not require LTC to confirm differences in the use of potentially inappropriate medications (PIMs), frequently used PIMs, and associating factors in Korea. METHODS: Using the Korean National Health Insurance Service cohort data, adults aged ≥ 65 years as of 2017 who were LTC beneficiaries (at home and LTC facilities) were selected and matched 1:1 with a control group (LTC non-beneficiaries). PIM was defined based on the 2019 American Society of Geriatrics Beers criteria. PIM use and medical resource utilization according to LTC requirements were compared for one year after the index date. After correcting for other confounding variables, differences in the risk of PIM use on person-based according to LTC eligibility were assessed using multivariate logistic regression. RESULTS: Among the 13,251 older adults requiring LTC in 2017, 9682 were matched with counterparts and included. Among those who received an outpatient prescription including PIM at least once yearly, 83.6 and 87.6% were LTC beneficiaries and LTC non-beneficiaries, respectively (p < 0.001). Using the number of outpatient prescriptions as the baseline, 37.2 and 33.2% were LTC beneficiaries and LTC non-beneficiaries, respectively (p < 0.001). In both groups, elevated PIM use depended on increased medical resource utilization, as shown by increased outpatient visits and medical care institutions visited. Adjusting other influencing factors, the need for LTC did not significantly associated with PIM use (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.84-1.04); the number of drugs consumed (3-4: OR 1.42, 95% CI 1.25-1.61; 5-9: OR 2.24, 95% CI 1.98-2.53; 10 and more: OR 3.72, 95% CI 3.03-4.55; reference group: 2 and less), frequency of visits (7-15: OR 1.95, 95% CI 1.71-2.23; 16-26: OR 3.51, 95% CI 3.02-4.07; 27-42: OR 5.84, 95% CI 4.84-7.05; 43 and more: OR 10.30, 95% CI 8.15-13.01; reference group: 6 and less), and visits to multiple medical care institutions (3-4: OR 1.96, 95% CI 1.76-2.19; 5 and more: OR 3.21, 95% CI 2.76-3.73; reference group: 2 and less) emerged as primary influencing factors. PIMs mainly prescribed included first-generation antihistamines, benzodiazepines, and Z-drugs in both groups; quetiapine ranked second-highest among LTC beneficiaries. CONCLUSIONS: The LTC demand did not significantly associated with PIM utilization. However, the number of drugs consumed, and the pattern of medical resource use were important factors, regardless of LTC requirements. This highlights the need to implement comprehensive drug management focusing on patients receiving polypharmacy and visiting multiple care institutions, regardless of LTC needs.

The invasive species are of global concern, and the Invasive American Bullfrog (IAB; Lithobates catesbeianus) is one of the worst invasive amphibian species worldwide. Like other countries, South Korea is also facing challenges from IAB. Although many studies indicated impacts of IAB on native anurans in Korea, the actual risk at the specific level is yet to evaluate. Considering the putative invasiveness of IAB, it is hypothesized that any species with the possibility of physical contact or habitat sharing with them, will have a potential risk. Thus, we estimated and observed their home range, preferred habitats, morphology, behavior, and ecology. Then, comparing with existing knowledge, we assessed risks to the native anurans. We found a home range of 3474.2 ± 5872.5 m2 and identified three types of habitats for IAB. The analyses showed at least 84% of native anurans (frogs and toads) were at moderate to extreme risks, which included all frogs but only 33% of toads. Finally, we recommended immediate actions to conserve the native anurans based on our results. As this study is the first initiative to assess the specific risk level from the invasiveness of L. catesbeianus, it will help the managers to set conservation priorities and strategies.

OBJECTIVE: To introduce our novel technique for myometrial defect closure after adenomyomectomy. MATERIALS AND METHODS: A retrospective cohort study. A total of 40 patients with adenomyosis who visited our clinic between October 2012 and January 2018 were recruited. Of those 34 patients were eligible for analysis. RESULTS: The mean thickness of the affected uterine wall before surgery was 4.02 cm ± 1.11, dropping to 2.37 cm ± 0.84 postoperatively. This led to a mean drop of 41% in the thickness of the affected wall, which was found to be significant using a paired t-test (p < 0.0001). The mean preoperative pain score was 8.68 ± 1.12, while the postoperative mean was 0.06 ± 0.34. The mean preoperative CA 125 was 121.73 ± 117.29, dropping to 6.95 ± 2.60 postoperatively. This was found to be significantly lower using both the Wilcoxon Signed Rank and Sign tests (p = 0.0156). CONCLUSION: Myometrial defect closure in a layer-by-layer fashion after robot-assisted laparoscopic adenomyomectomy is a reproducible technique. This uterine conserving method was effective in reducing our patients' pain. It may be the solution to maintaining adequate myometrial wall thickness, uterine layer alignment, and endometrial integrity.

As the population of the elderly in long-term care facilities has grown, the number of users of potentially inappropriate medication (PIM) is also increasing. With this study, we aimed to investigate the pattern of PIM usage and related factors among the elderly receiving long-term care services. Using the South Korean National Health Insurance Service Elderly Cohort Database, we conducted a retrospective matched cohort study. Elderly residents (nâ =â 1980) in long-term care facilities in 2013 were selected and matched 1:1 with elderly persons living in the community applying propensity score method. The matching variables were sex, age, health insurance type, long-term care grade, Charlson's Comorbidity Index score, presence of dementia, cerebrovascular disease, or Parkinson's disease, and number of drugs prescribed. PIM use was assessed according to Beers criteria 2019. The prevalence of PIM was found to be higher among the elderly in long-term care facilities (86.77%) than among community-dwelling individuals (75.35%). Logistic regression showed that long-term care facility residents were 1.84 odds more likely to use PIM than community-dwelling older adults. We also confirmed that the average number of medications taken per day and the number of outpatient visits were the major influencing factors affecting PIM prescriptions. In addition, elders living in long-term care facilities were prescribed more PIM drugs acting on the central nervous system than community-dwelling older adults. The results of this study show that among those receiving long-term care services, older people in long-term care facilities use PIM more than do the elderly living at home. Medication management programs need to be developed to reduce the use of PIM in long-term care facilities.

BACKGROUND/OBJECTIVES: While the use of food additives in food processing has become a common practice worldwide, consumers' worry about potential hazards has not diminished. The purpose of this study was to identify trends in South Korean parents' perceptions about food additives by analyzing the results of surveys conducted from 2014 to 2018. SUBJECTS/METHODS: We conducted an off-line survey in Korea annually between 2014 and 2018 on perceptions about food additives. The numbers of survey respondents in each year from 2014 to 2018 were 381, 426, 301, 519, and 369, respectively. Our consumer respondents were parents of elementary-school-aged children. RESULTS: The ratios of respondents perceiving "food safety" as the most important factor in purchasing processed foods and "food additives" as the biggest threat to food safety have decreased over the years. However, most consumers still have negative perceptions of food additives. Additionally, among consumers lower confidence in or trust of the Korean government continued throughout the study period and appeared to be the main problem that needs to be overcome. CONCLUSIONS: This study found that Korean parents are still troubled by food additives. Consumers' confidence in the government needs to be increased through public communications. More multifaceted educational programs communicating scientific knowledge of food additives are needed in order to correct consumers' misperceptions.
RESUMEN
The complete mitochondrial (mt) genome of Lithobates catesbeianus was sequenced and characterized. The circular mt genome was constituted of of 37 genes (13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs) and a non-coding region (NCR). Phylogenetic analysis based on the full mt genome sequences confirmed that among the genus Lithobates, L. catesbeianus Korea is included in a monophyletic group with L. catesbeianus China, but not with either L. catesbeianus Japan or L. catesbeianus Canada. This is the first completed mt genome from L. catesbeianus Korea, which provide data for further study of phylogeny in Lithobates spp. that have been introduced into a number of different countries originally from North America.
RESUMEN
BACKGROUND: Immigrants are vulnerable to suboptimal health care utilization including non-adherence of medication use. Thus, we aimed to identify the potential risk factors of non-adherence and evaluate whether utilizing a usual source of care was associated with medication adherence in immigrants. METHODS: We utilized the Korea National Health Insurance Claims Database between 2012 and 2015. Cases were immigrants who had antihypertensive prescriptions at the time of hypertension diagnosis in 2012. Controls were native-born Koreans with hypertension who were 1:1 matched to immigrants by age, sex, and Charlson comorbidity index. We used the medication possession ratio for three years to assess the adherence to antihypertensive drugs. The likelihood of non-adherence was evaluated between cases and controls by multivariate linear regression models stratified by age, sex, and number of clinic visits. We assessed the potential risk factors of non-adherence in immigrants by multivariate linear regression and logistic regression models, respectively. RESULTS: In total, 4114 immigrants and 4114 matched native-born Koreans with hypertension were included. The mean MPR was significantly lower in immigrants (56% vs 70%, p<0.0001). Immigrants showed almost two times the level of non-adherence as native-born Koreans (odds ratio [OR], 2.01; 95% confidence interval [CI], 1.83-2.21). Stratified analyses on non-adherence presented the highest non-adherence (2.28 times) in immigrants in the younger group (30-49 years old) and the lowest non-adherence in immigrants in 65 and old group where the risk was 1.69 times higher than native Korean with the same age. The absence of a usual source of care significantly increased medication non-adherence by 1.31 to 1.58 times among immigrants. CONCLUSION: When the number of visited clinics increased, the degree of non-adherence increased consistently. Therefore, the systematization of registering with primary care (a usual source of care) might be a modifiable health care strategy to improve health care outcomes in immigrants.
RESUMEN
OBJECTIVES: The lowest-low fertility status of Korea has continued for the past 17 years despite governmental efforts to encourage childbirth. As the number of working women has increased, their residence patterns have changed; however, the impact of this factor has yet to be explored. Therefore, this study was conducted to investigate the effects of residence patterns relative to the workplace on the total fertility rate of working women. METHODS: Information on eligibility and healthcare utilization was obtained from the National Health Information Database between 2011 and 2015. The study participants were working women aged 15-49 years. We classified their residence relative to their workplace into 3 patterns: same municipality, same province, and different province. The total fertility rate was calculated and logistic regression was performed of childbirth according to residence pattern, adjusting for age, insurance contribution quartile, size of the workplace, year of birth, and province of residence. RESULTS: The total fertility rates of working women from 2011 to 2015 were 1.091, 1.139, 1.048, 1.073, and 1.103, respectively. The total fertility rate by residence pattern was highest in women residing in the same municipality as their workplace. After adjustment, the odds of childbirth in women from the same municipality and the same province were 21.6% and 16.0% higher than those of women residing in a different province, respectively. CONCLUSIONS: The total fertility rate was higher among women living near their workplace. Therefore, effective policy measures should be taken to promote the proximity of working women's workplace and residence.

OBJECTIVES: To identify simultaneous behavioral changes in alcohol consumption, smoking, and weight using a fixed-effect model and to characterize their associations with disease status. METHODS: This study included 7 000 529 individuals who participated in the national biennial health-screening program every 2 years from 2009 to 2016 and were aged 40 or more. We reconstructed the data into an individual-level panel dataset with 4 waves. We used a fixed-effect model for smoking, heavy alcohol drinking, and overweight. The independent variables were sex, age, lifestyle factors, insurance contribution, employment status, and disease status. RESULTS: Becoming a high-risk drinker and losing weight were associated with initiation or resumption of smoking. Initiation or resumption of smoking and weight gain were associated with non-high-risk drinkers becoming high-risk drinkers. Smoking cessation and becoming a high-risk drinker were associated with normal-weight participants becoming overweight. Participants with newly acquired diabetes mellitus, ischemic heart disease, stroke, and cancer tended to stop smoking, discontinue high-risk drinking, and return to a normal weight. CONCLUSIONS: These results obtained using a large-scale population-based database documented interactions among lifestyle factors over time.

OBJECTIVE: Managing hypertension to prevent complications in patients with diabetes requires appropriate pharmacotherapy. This study aimed to analyze healthcare provider factors influencing prescriptions of angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) as the first-line therapy in managing hypertension among patients with diabetes in primary care. MATERIALS: This study used National Health Insurance Claims Data in Korea. METHODS: We calculated the prescription rate of angiotensin-converting enzyme inhibitors (ACE inhibitors) or ARBs by dividing the number of patients prescribed an ACE inhibitor or an ARB by the number of patients with diabetes prescribed hypoglycemic agents and antihypertensive agents. We performed a logistic regression to investigate the factors influencing the prescription rate of ACE inhibitors or ARBs. RESULTS: The mean prescription rate of ACE inhibitors or ARBs was 69.8%. The prescription rate of ACE inhibitors or ARBs decreased with increasing physician and patient age. The rate was higher for male patients than for females. The rate was higher in institutions with a greater number of physicians and among internists than among general practitioners, surgery-related and internal medicine-related specialists. The rate was significantly influenced by the mean monthly number of patients with hypertension per medical institution, the number of physicians per medical institution, and the physician's age and specialty. CONCLUSION: The age and specialty of the prescribing physician influenced the use of ACE inhibitors or ARBs in patients with diabetes and hypertension in primary care. Efforts are needed to promote information exchange among physicians and the appropriate prescriptions of antihypertensive agents in patients with diabetes and hypertension in primary care.

BACKGROUND: It is imperative to address the health problems faced by immigrants in their destination countries in light of the current magnitude of migration processes worldwide. We aimed to evaluate the socioeconomic determinants of healthcare utilization in immigrants with depression. METHOD: A population-based cohort comprising all immigrants who were eligible for National Health Insurance coverage (permanent residents, marriage immigrants, and naturalized citizens) using the National Health Insurance Claims Database in 2011-2013 was established. Cases were defined as immigrants with new-onset depression. Controls were new-onset Korean patients with depression matched by age, sex, and Charlson comorbidity index in a 1:2 ratio. Appropriateness of care (AOC) was defined as visiting a clinic for depression management at least 3 times in the first 12 weeks and 4 times thereafter until 12 months post-cohort entry. RESULTS: A total of 2,378 immigrants and 4,756 matched Korean patients were identified. Of the immigrants, 30.0% achieved AOC, in contrast to 38.7% of Koreans (p < .0001). Adjusting for possible covariates, AOC was less likely for immigrants (adjusted OR (aOR), 0.760; 95% CI: 0.670-0.863). Medical Aid (aOR, 2.309; 95% CI, 1.479-3.610), rural residence (aOR, 1.536; 95% CI, 1.054-2.237), the presence of a psychiatric comorbidity (aOR, 1.912; 95% CI, 1.484-2.463), and visiting a psychiatrist (aOR, 2.387; 95% CI, 1.821-3.125) were associated with an increased likelihood of AOC in immigrants. CONCLUSION: Socioeconomic determinants included insurance type (Medical Aid and National Health Insurance), place of residence, psychiatric comorbid status, doctor specialty, easy access to medical services (clinic-based), and a SSRI-based treatment regimen. Those predictors should be taken into account when developing healthcare strategies for immigrants.

This study determined the effects of anti-diabetic medication adherence on the long-term all-cause mortality and hospitalization for cerebrovascular disease and myocardial infarction among newly diagnosed patients. The study used retrospective cohort from the National Health Insurance Service. Study participants were 65,076 newly diagnosed type 2 diabetes mellitus patients aged ≥40 years. The medication adherence was evaluated from the proportion of days covered (PDC) between 2006 and 2007. Outcome variables were mortality, newly diagnosed cerebrovascular disease (CVD) and myocardial infarction (MI) in 2008-2017. Cox-proportional hazard regression analysis was performed. After adjusting for sex, age, monthly contribution, insurance type, medical institution type, Charlson comorbidity index score, disability, hypertension, and active ingredients of oral hypoglycemic agents, the adjusted hazard ratio (aHR) for all-cause-mortality of the lowest PDC group (<0.20) was 1.45 (95% confidence interval [CI] = 1.36-1.54) as compared to the highest PDC (≥0.8). The aHR for all-cause-mortality associated with PDC levels of 0.60-0.79, 0.40-0.59, and 0.20-0.39 were 1.19, 1.26, and 1.34, respectively (Ptrend < 0.001). Compared to the highest PDC group, diabetic patients with the lowest PDC had elevated risk for CVD (aHR = 1.41; 95% CI = 1.30-1.52; Ptrend < 0.001). Improving anti-diabetic medication adherence among newly diagnosed type 2 diabetes mellitus patients is essential to the reduce risk for cardiovascular disease and long-term all-cause mortality.

OBJECTIVES: The objectives of this study were to investigate the agreement between medical history questionnaire data and claims data and to identify the factors that were associated with discrepancies between these data types. METHODS: Data from self-reported questionnaires that assessed an individual's history of hypertension, diabetes mellitus, dyslipidemia, stroke, heart disease, and pulmonary tuberculosis were collected from a general health screening database for 2014. Data for these diseases were collected from a healthcare utilization claims database between 2009 and 2014. Overall agreement, sensitivity, specificity, and kappa values were calculated. Multiple logistic regression analysis was performed to identify factors associated with discrepancies and was adjusted for age, gender, insurance type, insurance contribution, residential area, and comorbidities. RESULTS: Agreement was highest between questionnaire data and claims data based on primary codes up to 1 year before the completion of self-reported questionnaires and was lowest for claims data based on primary and secondary codes up to 5 years before the completion of self-reported questionnaires. When comparing data based on primary codes up to 1 year before the completion of self-reported questionnaires, the overall agreement, sensitivity, specificity, and kappa values ranged from 93.2 to 98.8%, 26.2 to 84.3%, 95.7 to 99.6%, and 0.09 to 0.78, respectively. Agreement was excellent for hypertension and diabetes, fair to good for stroke and heart disease, and poor for pulmonary tuberculosis and dyslipidemia. Women, younger individuals, and employed individuals were most likely to under-report disease. CONCLUSIONS: Detailed patient characteristics that had an impact on information bias were identified through the differing levels of agreement.

Medication errors threaten patient safety by requiring admission, readmission, and/or a longer hospital stay, and can even be fatal. Near-misses indicate the potential for medication errors to have occurred. Therefore, reporting near-misses is a first step in preventing medication errors. The aim of this study was to estimate the reporting rate of near-misses among pharmacists in Korean hospitals, and to identify the factors that contributed to reporting medication errors.We surveyed 245 pharmacists from 32 hospital pharmacies for medication errors, including near-misses. We asked them to describe their experiences of near-misses in dispensing, administration, and prescribing, and to indicate the percentage of near-misses that they reported. Additionally, we asked questions related to the perception of medication errors and barriers to reporting medication errors. These questions were grouped into 4 categories: protocol and methods of reporting, incentives and protections for reporters, attitude related to reporting, and fear. Descriptive statistics and logistic regression were conducted to analyze the data.Five or more near-misses per month were experienced by 14.8%, 4.3%, and 43.9% of respondents for dispensing, administration, and prescribing errors, respectively. The percentages of respondents who stated that they reported all near-misses involving dispensing errors, administration errors, and prescribing errors were 43.7%, 57.4%, and 37.1%, respectively. Unclear reporting protocols and the absence of harm done to patients were significant factors contributing to the failure to report medication errors (Pâ<â.05).Advances can still be made in the frequency of reporting near-misses. Clear and standardized policies and procedures are likely to increase the reporting rates.

PURPOSE: The National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) is a cohort of participants who participated in health screening programmes provided by the NHIS in the Republic of Korea. The NHIS constructed the NHIS-HEALS cohort database in 2015. The purpose of this cohort is to offer relevant and useful data for health researchers, especially in the field of non-communicable diseases and health risk factors, and policy-maker. PARTICIPANTS: To construct the NHIS-HEALS database, a sample cohort was first selected from the 2002 and 2003 health screening participants, who were aged between 40 and 79 in 2002 and followed up through 2013. This cohort included 514 866 health screening participants who comprised a random selection of 10% of all health screening participants in 2002 and 2003. FINDINGS TO DATE: The age-standardised prevalence of anaemia, diabetes mellitus, hypertension, obesity, hypercholesterolaemia and abnormal urine protein were 9.8%, 8.2%, 35.6%, 2.7%, 14.2% and 2.0%, respectively. The age-standardised mortality rate for the first 2 years (through 2004) was 442.0 per 100 000 person-years, while the rate for 10 years (through 2012) was 865.9 per 100 000 person-years. The most common cause of death was malignant neoplasm in both sexes (364.1 per 100 000 person-years for men, 128.3 per 100 000 person-years for women). FUTURE PLANS: This database can be used to study the risk factors of non-communicable diseases and dental health problems, which are important health issues that have not yet been fully investigated. The cohort will be maintained and continuously updated by the NHIS.

The purpose of this study was to determine the perceptions and information needs of food experts, teachers, nutrition teachers, members of nongovernmental organizations, and general consumers concerning food additives. Questions in a survey format included perceptions, information needs, and preferred communication channels. The survey was conducted both off-line and on-line via e-mail and Google Drive in March 2015. The results indicated that most Korean consumers are concerned about the safety of using food additives in processed foods and do not recognize these additives as safe and useful materials as part of a modern diet. We also identified perception gaps among different groups regarding food additives. Nutrition teachers and members of nongovernmental organizations in Korea appeared to have a biased perception of food additives, which may cause general consumers to have a negative perception of food additives. The group of food experts did not have this bias. Governmental institutions must overcome the low confidence levels of various groups as an information provider about food additives. Based on the findings in this study, it will be possible to develop a strategy for risk communication about food additives for each group.

Physicochemical properties and oxidative stabilities of mealworm (Tenebrio molitor) oils under different roasting conditions were investigated. Oils were extracted using n-hexane from mealworms roasted at 200°C for 0, 5, 10, and 15 min and physicochemical properties and oxidative stabilities of oils were analyzed. Roasting increased the color intensity and the oleic acid and δ-tocopherol contents, but decreased linoleic acid, and α- and γ-tocopherol contents. An improvement in oxidative stability was observed in roasted mealworm oils, demonstrated by induction time and peroxide values. Mealworm oil contained abundant essential fatty acids and exhibited a superior oxidative stability.
