ABSTRACT

Objectives@#This study aimed to assess the scale and transmission patterns of coronavirus disease 2019 (COVID-19) in a religious village community in South Korea, to determine the risk factors of transmission, and to evaluate vaccine effectiveness. @*Methods@#An epidemiological survey was conducted, and data were collected and analyzed from 602 villagers in the religious village community. Multivariate logistic regression analysis was used to identify the risk factors for COVID-19 transmission and to evaluate vaccine effectiveness. @*Results@#The outbreak attack rate was 72.1% (434/602). The attack rate was high among women in their 60s, the unemployed, residents living near religious facility (<500 m), and the unvaccinated. Age, the distance between religious facility and residences, and the absence of vaccination were identified as risk factors for infection. Vaccine effectiveness was 49.0%, and the highest effectiveness was seen in the age group of 59 years or younger (65.8%). @*Conclusion@#This village community was isolated, with little communication with the outside world. However, the frequency of close contact between residents was relatively high, contributing to the spread of COVID-19 in the village even with relatively short exposure. Vaccination rates in the village community were also lower than those in the general public. Public health authorities should consider the potential impact of cultural factors, including religion, that could lead to the exponential spread of COVID-19 in closed village communities.

ABSTRACT

Background@#and Objective: With the advancement of cancer treatments and increased life expectancy, managing breakthrough cancer pain (BTcP) is essential to improve the quality of life for cancer patients. This study aimed to compare the major rapid onset opioids in Korea based on their characteristics and costs to determine the best option for each patient. @*Methods@#Based on sales information from IQVIA-MIDAS, sublingual fentanyl tablet (SLF), fentanyl buccal tablet (FBT), and oral transmucosal fentanyl citrate (OTFC) were selected as the top three drugs for the treatment of BTcP in Korea, considering them the most comparable drugs. The cost and cost-pain relief ratio of the drugs for short-term (1 month) and long-term (1 year) treatment were compared and the ease of administration based on various factors, including pharmacokinetics, onset of action, and administration procedures were evaluated. @*Results@#SLF was evaluated as the best overall in terms of rapid onset of action, ease of administration, and drug cost and also had the highest market share. SLF had the lowest cost pain relief ratio for both the initial and supplemental treatment for the 1-month pain intensity difference 15 (PID15) ratio. However, for the 1-month PID30 ratio, SLF was not superior to OTFC or FBT. The longer the breakthrough cancer pain duration, the more cost-effective the other rapid onset opioids. @*Conclusion@#The rapid onset opioids that fit the patient’s breakthrough cancer pain pattern have the best cost-effectiveness.

ABSTRACT

Purpose@#This quasi-experimental single group study aimed to confirm the effects of discharge education using a systematic discharge education program on anxiety and parenting confidence in mothers of premature babies. @*Methods@#This study conducted discharge education for 3 to 5 days prior to the discharge of 29 mothers of premature babies born in the neonatal intensive care unit. Data were collected between April 1, 2021, to June 30, 2021, and were examined. The hypotheses were analyzed using the Wilcoxon signed-rank test. @*Results@#Discharge education using a systematic discharge education program was effective in increasing the parenting confidence of mothers with premature babies (z=-3.839, p<0.001). However, it was not effective in reducing anxiety (z=-1.712, p=0.087). @*Conclusion@#The effects of the systematic discharge education program development and discharge education systematized discharge nursing education, reduced mothers’ anxiety in raising premature babies at home after discharge, and contributed to improving parenting confidence.

ABSTRACT

Background@#Many studies have evaluated the prevalence of different reasons for retraction in samples of retraction notices. We aimed to perform a systematic review of such empirical studies of retraction causes. @*Methods@#The PubMed/MEDLINE database and the Embase database were searched in June 2023. Eligible studies were those containing sufficient data on the reasons for retraction across samples of examined retracted notices. @*Results@#A 11,181 potentially eligible items were identified, and 43 studies of retractions were included in this systematic review. Studies limited to retraction notices of a specific subspecialty or country, journal/publication type are emerging since 2015. We noticed that the reasons for retraction are becoming more specific and more diverse. In a meta-analysis of 17 studies focused on different subspecialties, misconduct was responsible for 60% (95% confidence interval [CI], 53–67%) of all retractions while error and publication issues contributed to 17% (95% CI, 12–22%) and 9% (95% CI, 6–13%), respectively. The end year of the retraction period in all included studies and the proportion of misconduct presented a weak positive association (coefficient = 1.3% per year, P = 0.002). @*Conclusion@#Misconduct seems to be the most frequently recorded reason for retraction across empirical analyses of retraction notices, but other reasons are not negligible. Greater specificity of causes and standardization is needed in retraction notices.

ABSTRACT

Background@#Topical corticosteroids (TCs) are available both as over-the-counter drugs and prescription medicines at pharmacies.Although they are generally safe drugs, inappropriate and excessive use could result in potential side effects. Thus, it is important to have appropriate knowledge regarding the use of TCs. We performed a cross-sectional survey to assess public knowledge and the potential misuse or overuse of TCs. @*Methods@#A cross-sectional and nationwide online survey was conducted among participants who were aware of TCs. The survey items included sources of information, indications, potential side effects, and methods of application of TCs. A comparative analysis was conducted between those with (TC users) and without (TC non-users) an experience of using TCs. Results: Among 3,000 participants, 74.4% were TC users. The mass media was the most common information source of TCs, and only one-third of the surveyed people relied on pharmacists or doctors for information. Regarding indications and application methods, incorrect answer rate was high in some items, but respondents showed adequate knowledge. However, awareness of the safety of TCs was low. Overall, the TC users showed a higher knowledge of TCs than TC non-users. @*Conclusions@#Public knowledge of the use of TCs appears to be appropriate. However, we found potential misuse or overuse of some items and a lack of awareness of the side effects concerning TCs. Thus, healthcare professionals’ significant role is required.

ABSTRACT

Objective@#To evaluate the efficacy and safety of 8 weeks of resistance circuit training in people with paraplegia due to spinal cord injury. @*Methods@#Participants were randomized into experimental and control groups. Although the intensity and sequence of movements of the exercise programs were identical in both groups, the resting time between sets was limited to 1 minute in the experimental group. In the control group, the participants were allowed to rest until they were comfortable. Both groups received 8 weeks of training twice per week. Before and after the program, muscle mass, body fat percentage, fat mass, blood pressure, heart rate, muscle strength and muscular endurance were evaluated, and 6-minute propulsion test was conducted. Additionally, the safety of the program was assessed. @*Results@#Twenty-two individuals with paraplegia were enrolled (11 in each group). After the training program, the experimental group showed a significant decrease in the resting blood pressure and improvement in the upper extremity muscle mass, strength, and endurance (p<0.05). Each variable showed significant inter-group differences (p<0.05). Furthermore, none of the participants showed autonomic adverse events, musculoskeletal side effects, or discomfort. @*Conclusion@#The results show that resistance circuit training programs with short resting intervals are superior to the usual resistance exercise programs in improving the blood pressure and physical strength and are safe for people with upper thoracic level injuries at T6 or higher.

ABSTRACT

Background@#The need for regulatory science development to evaluate advanced regulatory products is gradually increasing without hindering the technological development. Creating a research environment and fostering experts through the establishment of regulatory agency-led policies are essential for the development of regulatory science. Method: This is a comparative study of the United States, Japan, Singapore, and Korea. The literature and websites of each regulatory agency were reviewed, and the focus was on advantages and comparing advantages based on definition, development trends, and expert training projects. @*Results@#The United States is striving to develop regulatory science in response to changes in the new pharmaceutical industry through the regulatory science report, and to foster expert both inside and outside the Food and Drug Administration (FDA). Japan is promoting regulatory science centered on regulatory science centers, and is focusing on researching work-related regulatory science within the Pharmaceuticals and Medical Devices Agency (PMDA) and improving employees’ ability to make regulatory decisions. Singapore was aiming to improve Southeast Asia’s regulatory capabilities under the leadership of Centre of Regulatory Excellence (CoRE) within Duke-NUS University. In 2021, Korea is in its early stages, starting to run a university's degree program related to regulatory science this year. @*Conclusion@#Regulatory science should be developed with the aim of improving the regulatory ability of the Ministry of Food and Drug Safety with Korea’s independent concept of regulatory science.

ABSTRACT

Purpose@#Food allergies in children are known to impact the quality of life for growing children as well as their parents. This study investigates the status of food allergy and its management among preschoolers, and evaluates the effect on parental burden. @*Methods@#In May 2019, five kindergartens and daycare centers in Jeju area were randomly selected, and parents (n = 638) who had preschoolers younger than 6-year-old were surveyed using a questionnaire. A total of 387 participants were included in the final data analysis. @*Results@#The percentage of children (aged 3 to 6 years old) who experienced food allergies was 16.8%; 44.6% had been diagnosed as having a food allergy by doctors. Food allergies were first experienced in more than two-thirds of the subjects when they were less than a year old. Egg and milk were the most frequent allergenic foods with some skin related symptoms. A mere 15.4% children suffering from food allergies were offered substitutes for their allergenic foods. Lastly, as compared to other parents, the parents of children who experienced food allergies had not only higher nutritional knowledge, but also heavier parental burden including emotional distress. Regardless of their nutritional knowledge, parents of children with food allergy expressed their willingness to attend nutrition education classes, if available in future. @*Conclusion@#For prevention of food allergies and proper nourishment of children with food allergies, there is a necessity to provide customized-nutritional education for the affected parents to help alleviate their parental burden, especially for reducing emotional distress.

ABSTRACT

Background@#Korea’s health screening program has been faced the need for changes as the population and diseases structure are changing. In addition to Korea, many countries operate state-led health check-up programs to improve the health level of the people, and the operating methods of the program appear in various forms according to each country’s health insurance system. This study examines other state-led health screening programs and proposes a direction for the development of Korea’s health screening program. @*Methods@#The study was conducted using the literature review method, and the “country” was set as a unit for the case analysis. The operating method of the health screening programs and the financial resources were compared according to the health insurance system. Five countries were selected as Korea, the United States, the United Kingdom, Japan, and Taiwan. @*Results@#The analyzed countries mainly operate the health screening program as a management method for chronic diseases, but there were differences in the operating method, financing, and targeted subjects and examination items. In most countries, a risk assessment was performed prior to the examination (screening), and the subjects who needed the examination were first selected, and a follow-up management service was provided in accordance with the risk each individual exposed. @*Conclusion@#Rather than applying the same screening method to populations with different risk levels, a health screening program will be constructed in consideration of the individual’s health level and exposure risk, and the healthcare delivery system will be reorganized so that screening and treatment services can be linked.

ABSTRACT

Objective@#To assess the incidence of urinary tract infection (UTI) with post-urodynamic study (post-UDS) in patients with spinal cord injury (SCI) and study its relationship with pre-UDS pyuria. @*Methods@#Patients with SCI who were hospitalized and underwent UDS during a 4-year period were reviewed. Patients with pre-test lower urinary tract symptoms were excluded. Urinalysis and urine culture were performed before and 24 hours after UDS. Prophylactic antibiotics were administered for 5 days starting from the morning of the UDS. UTI was defined as bacteriuria with accompanying symptoms. @*Results@#Of 399 patients reviewed, 209 (52.4%) had pyuria in pre-UDS urinalysis, and 257 (64.4%) had bacteriuria in pre-UDS culture. Post-UDS UTI occurred in 6 (1.5%) individuals who all complained of fever: 5 (2.4%) of the post-UDS UTI cases occurred in patients with pre-UDS pyuria, and 1 (0.5%) in a person without. The differences between groups were not statistically significant (p=0.218). Of 221 patients with bacteriuria (gram-negative isolates) on pre-UDS culture, resistance to ciprofloxacin, cephalosporin, and trimethoprim/sulfamethoxazole (TMP/SMT) was noted in 52.9% (117 cases), 57.0% (126 cases), and 38.9% (86 cases), respectively. @*Conclusion@#No difference was found in the prevalence of post-UDS UTI based on the presence of pyuria in pre-UDS urinalysis. UDS may be performed even in SCI cases of pre-UDS pyuria without increasing the prevalence of post-UDS UTI if prophylactic antibiotics are administered. TMP/SMT could be used as a first-line antibiotic for the prevention of post-UDS UTI in Korea.

ABSTRACT

BACKGROUND/OBJECTIVES@#The present study aimed to further investigate the potential health beneficial effects of long-term seaweed supplementation on lipid metabolism and hepatic functions in DIO mice.MATERIALS/METHODS: Four brown seaweeds (Undaria pinnatifida [UP], Laminaria japonica [LJ], Sargassum fulvellum [SF], or Hizikia fusiforme [HF]) were added to a high fat diet (HFD) at a 5% ratio and supplemented to C57BL/6N mice for 16 weeks. Triglycerides (TGs) and total cholesterol (TC) in the liver, feces, and plasma were measured. Fecal bile acid (BA) levels in feces were monitored. Hepatic insulin signaling- and lipogenesis-related proteins were evaluated by Western blot analysis. @*RESULTS@#Fasting blood glucose levels were significantly reduced in the LJ, SF, and HF groups compared to the HFD group by the end of 16-week feeding period. Plasma TG levels and hepatic lipid accumulation were significantly reduced in all 4 seaweed supplemented groups, whereas plasma TC levels were only suppressed in the UP and HF groups compared to the HFD group. Fecal BA levels were significantly elevated by UP, LJ, and SF supplementation compared to HFD feeding only. Lastly, regarding hepatic insulin signaling-related proteins, phosphorylation of 5′-AMP-activated protein kinase was significantly up-regulated by all 4 types of seaweed, whereas phosphorylation of protein kinase B was up-regulated only in the SF and HF groups. Lipogenesis-related proteins in the liver were effectively down-regulated by HF supplementation in DIO mice. @*CONCLUSIONS@#Brown seaweed consumption showed hypotriglyceridemic effects in the prolonged DIO mouse model. Specifically, combinatory regulation of BA excretion and lipogenesis-related proteins in the liver by seaweed supplementation contributed to the reduction of plasma and hepatic TG levels, which inhibited hyperglycemia in DIO mice. Thus, the discrepant and species-specific functions of brown seaweeds provide novel insights for the selection of future targets for therapeutic agents.

ABSTRACT

Objective@#To identify the prevalence and characteristics of neuropathic pain (NP) in patients with spinal cord injury (SCI) and to investigate associations between NP and demographic or disease-related variables. @*Methods@#We retrospectively reviewed medical records of patients with SCI whose pain was classified according to the International Spinal Cord Injury Pain classifications at a single hospital. Multiple statistical analyses were employed. Patients aged <19 years, and patients with other neurological disorders and congenital conditions were excluded. @*Results@#Of 366 patients, 253 patients (69.1%) with SCI had NP. Patients who were married or had traumatic injury or depressive mood had a higher prevalence rate. When other variables were controlled, marital status and depressive mood were found to be predictors of NP. There was no association between the prevalence of NP and other demographic or clinical variables. The mean Numeric Rating Scale (NRS) of NP was 4.52, and patients mainly described pain as tingling, squeezing, and painful cold. Females and those with below-level NP reported more intense pain. An NRS cut-off value of 4.5 was determined as the most appropriate value to discriminate between patients taking pain medication and those who did not. @*Conclusion@#In total, 69.1% of patients with SCI complained of NP, indicating that NP was a major complication. Treatment planning for patients with SCI and NP should consider that marital status, mood, sex, and pain subtype may affect NP, which should be actively managed in patients with an NRS ≥4.5.

ABSTRACT

PURPOSE: This study compared the temporal artery temperature (TAT) measured by infrared temporal artery thermometers to the axillary temperature (AT) measured by standard mercury-in-glass thermometers, and evaluated accuracy of the TAT measurement for clinical practice. METHODS: A total of 247 adult inpatients in general wards in a tertiary medical center located in Seoul participated in the study. The TAT was measured within one minute after the AT measurement. Data were analyzed using descriptive statistics, paired t-test, Pearson correlation coefficient, linear regression, and the Bland-Altman plot. RESULTS: There was a significant difference in mean temperature between AT and TAT, 36.89℃ (SD=0.70) versus 37.35℃ (SD=0.72). The Bland-Altman plots demonstrated the difference between the AT and TAT as −1.29 to +0.33. The specificity and sensitivity of the TAT in detecting fever were high. The positive predictive values were 57.5% and 71.0% when the AT were higher than 38.0℃ and the TAT fever cutoff levels were 38.0℃ and 38.3℃ respectively. CONCLUSION: TAT and AT were highly correlated and agreeable, indicating that TAT is as accurate as AT. The findings suggested that TAT measurement can be used in clinical practice. For accurate communication between medical personnel, medical institutions need to provide guidelines for temperature measurement, especially for the use of thermometer and measurement sites.

ABSTRACT

BACKGROUND: High-NaCl diet is a contributing factor for cardiac hypertrophy. The role of HSP22 as a protective protein during cardiac hypertrophy due to hypernatremia is unclear. Accordingly, this study aimed to establish a cellular hypernatremic H9C2 model and to compare the expression of HSP22 in Ca2+ homeostasis between a high-NaCl and angiotensin II-induced hypertrophic cellular H9C2 model. METHODS: Real-time PCR was performed to compare the mRNA expression. Flow cytometry and confocal microscopy were used to analyze the cells. RESULTS: The addition of 30 mM NaCl for 48 h was the most effective condition for the induction of hypertrophic H9C2 cells (termed the in vitro hypernatremic model). Cardiac cellular hypertrophy was induced with 30 mM NaCl and 1 µM angiotensin II for 48 h, without causing abnormal morphological changes or cytotoxicity of the culture conditions. HSP22 contains a similar domain to that found in the consensus sequences of the late embryogenesis abundant protein group 3 from Artemia. The expression of HSP22 gradually decreased in the in vitro hypernatremic model. In contrast to the in vitro hypernatremic model, HSP22 increased after exposure to angiotensin II for 48 h. Intracellular Ca2+ decreased in the angiotensin II model and further decreased in the in vitro hypernatremic model. Impaired intracellular Ca2+ homeostasis was more evident in the in vitro hypernatremic model. CONCLUSION: The results showed that NaCl significantly decreased HSP22. Decreased HSP22, due to the hypernatremic condition, affected the Ca2+ homeostasis in the H9C2 cells. Therefore, hypernatremia induces cellular hypertrophy via impaired Ca2+ homeostasis. The additional mechanisms of HSP22 need to be explored further.

ABSTRACT

PURPOSE: The purpose of this study was to investigate the occurrence of first onset of constipation during the rehabilitation stage and risk factors for constipation in patients with cerebral vascular disease (CVD). METHODS: Participants for this retrospective study were 214 CVD patients admitted to rehabilitation units. First onset of constipation and factors influencing constipation such as dependency level were recorded for 14 days during the rehabilitation stage. Survival analysis with Cox proportional hazard model and descriptive statistics were conducted. RESULTS: Age, patients'severity, types of diet, and dependency level were different between constipation and non-constipation groups. In survival analysis, 99% of participants developed constipation within 14 days after admission to rehabilitation units. Median constipation occurrence time was 7.4 days. Patients who were immobile and had tube feedings were more likely to develop constipation 4.07 times (95% CI: 1.018~16.301, p=.047) and 2.09 times (95% CI: 1.001~4.377, p=.050) respectively compared to patients who were independent and had a regular diet, respectively. CONCLUSION: Most CVD patients experienced constipation within 2 weeks after entering the rehabilitation stage. Constipation was linked to types of diet and dependency level. These factors associated with constipation should be considered when caring for patients in rehabilitation.
