RESUMO
Body size perception among young women in Asian and Western countries is believed to be quite different, however, there are no confirming studies. We analyzed the data from young women aged between 20 and 40 who participated in the National Health and Nutrition Examination Survey (2001-2018) of the United States (US) and Korea. US young women had higher rates of being overweight and obesity than Korean young women, and there was no significant change over 20 years. In both countries, the percentage of properly estimating one's own weight exceeded 70 percent and remained relatively steady. The percentage of overestimating one's own weight was only about 10 percent in Korea in 2001, but increased to 20 percent. In the case of the US, the percentage was about 15 percent in 2001-2002, but has since continued to decline. The percentage of underestimating one's own body weight was about 18 percent in Korea in 2001, but decreased to about 8 percent. In the case of the US, the percentage was very low at about 10 percent in 2001-2002, but gradually increased to about 18 percent in 2017-2018. In conclusion, young women in the US tend to underestimate their body size, and those in Korea tend to overestimate it.

The purpose of this study was to demonstrate the reliability and validity of the Korean version of the Caregiver Burden Inventory (CBI). The study was conducted as a multicenter cross-sectional survey for caregivers caring for patients with disabilities in outpatient or inpatient rehabilitation clinics. Sociodemographic characteristics and health-related quality of life were collected via questionnaires. The CBI and Burden Interview (BI) were administered, after which internal consistency and factor analysis of the CBI and correlation between the CBI and BI were explored. A total of 151 caregivers participated. The mean age of caregivers was 53.7 ± 12.4 years, and 80.8 % were women. The majority of caregivers were the main caregivers of stroke, spinal cord injury or traumatic brain injury. The factor analysis confirmed its five factorial structure. The time-dependence and physical burden scores of CBI were higher than those of other factors. All five-dimensional and total scores of CBI showed high internal consistency and were well correlated with BI. In conclusion, the CBI has proven its reliability, construct validity and concurrent validity for caregivers of disabled people and has shown its advantage as a multidimensional measure.

DNA methylation, and consequent down-regulation, of tumour suppressor genes occurs in response to epigenetic stimuli during cancer development. Similarly, human oncoviruses, including human papillomavirus (HPV), up-regulate and augment DNA methyltransferase (DNMT) and histone deacetylase (HDAC) activities, thereby decreasing tumour suppressor genes (TSGs) expression. Ubiquitin-like containing PHD and RING finger domain 1 (UHRF1), an epigenetic regulator of DNA methylation, is overexpressed in HPV-induced cervical cancers. Here, we investigated the role of UHRF1 in cervical cancer by knocking down its expression in HeLa cells using lentiviral-encoded short hairpin (sh)RNA and performing cDNA microarrays. We detected significantly elevated expression of thioredoxin-interacting protein (TXNIP), a known TSG, in UHRF1-knockdown cells, and this gene is hypermethylated in cervical cancer tissue and cell lines, as indicated by whole-genome methylation analysis. Up-regulation of UHRF1 and decreased TXNIP were further detected in cervical cancer by western blot and immunohistochemistry and confirmed by Oncomine database analysis. Using chromatin immunoprecipitation, we identified the inverted CCAAT domain-containing UHRF1-binding site in the TXNIP promoter and demonstrated UHRF1 knockdown decreases UHRF1 promoter binding and enhances TXNIP expression through demethylation of this region. TXNIP promoter CpG methylation was further confirmed in cervical cancer tissue by pyrosequencing and methylation-specific polymerase chain reaction. Critically, down-regulation of UHRF1 by siRNA or UHRF1 antagonist (thymoquinone) induces cell cycle arrest and apoptosis, and ubiquitin-specific protease 7 (USP7), which stabilises and promotes UHRF1 function, is increased by HPV viral protein E6/E7 overexpression. These results indicate HPV might induce carcinogenesis through UHRF1-mediated TXNIP promoter methylation, thus suggesting a possible link between CpG methylation and cervical cancer.

OBJECTIVE: This study aimed to evaluate the hospital adverse outcomes (HAO) of admitted older adult patients in a large prospective cohort and investigate the demographic, economic, and health-related characteristics at risk of HAO in all older adult patients admitted in the general ward of a tertiary referral hospital. MATERIALS AND METHODS: We recruited admission episodes of older adult patients aged over 65 years who were admitted at the general ward of Konkuk University Medical Center, which is a tertiary referral hospital, from September 2016 to October 2017. Out of 9,586 admission episodes, 8,263 were included. Modified from the Geriatric Screening for Care-10, six common geriatric health issues, namely, dysphagia, polypharmacy, fecal incontinence, functional mobility, depression, and dementia, were evaluated. Fall, hospital-acquired pressure ulcer (HPU), and mortality were checked daily by experienced nurses during the patients' hospital stay. A logistic regression model was used, and P < 0.05 was the threshold of significance. RESULTS: The incidence rates of fall and HPU were 1.3 % and 4.0 %, respectively. The hospital mortality was 6.1 %. Older adult patients with dysphagia or dementia upon admission were significantly associated with an increased likelihood of falls. Furthermore, age, ER admission, low income, fecal incontinence, or functional immobility increased the HPU incidence. Meanwhile, age, male, ER admission, fecal incontinence, or functional immobility significantly increased the hospital mortality. CONCLUSION: All demographic, economic, and health-related characteristics, except for polypharmacy and depression, affect the incidence of HAO. Intervention to vulnerable older adult patients with HAO risk could improve the treatment outcome.

BACKGROUND: This study aimed to describe the experience of providing older adult patients with transitional care from an acute care hospital to home in cooperation with a public health center, in order to present the barriers to that care and suggest better organizational methods. METHODS: This was a cross-sectional study to show the results of the Geriatric Screening for Care-10 (GSC-10) and outcomes of transitional care. Among 659 hospitalized patients aged 65 years or above who lived in an administrative district, forty-five subjects were enrolled between June 24, 2019 and January 23, 2020. Within 48 hours of admission, using the 10 areas of GSC-10, they were assessed for cognitive impairment, depression, polypharmacy (5 or more medications), functional mobility, dysphagia, malnutrition, pain, and incontinence, and were reassessed before discharge. The transitional care plan (containing the treatment summary, the results of the GSC-10 assessment, and the post-discharge plan) was forwarded to a representative of the public health center, who provided continued disease management and various health care services, such as chronic disease and frailty care, and physical rehabilitation. RESULTS: Of all the participants, 64.4% had more than 1 GSC-10 concern. The most prevalent concerns were functional immobility (35.6%) and polypharmacy (22.2%). About 15.6% of the participants were readmitted to a nursing home or hospital. A total of 38 participants received the transitional care intervention. They received an average of 2.7 administered interventions. However, the rate of rejection was high (30.1%) and patients were visited an average of 16.5 days after discharge. CONCLUSION: Through our experience of providing transitional care from an acute care hospital to home in cooperation with a public health center, we expect that the transitional care suitable for the Korean medical situation could be established and successful.

The aim of this comparative study involving pre- and post-tests was to analyze the effectiveness of patient safety educational materials developed for the Comprehensive Plans for Patient Safety in Korea (2018-2022), and to suggest how to improve patient safety literacy. A face-to-face survey interview comprising items related to general information and patient safety literacy was completed by 217 patients and their families who visited three general hospitals in Seoul and one general hospital in Gyeonggi-do for treatment between 25 October and 15 November 2019. In the interview, the patients were asked questions about whether the patient safety educational materials were "easy to understand," provided "help in safe hospitalization," and enabled patients to practice patient safety independently ("do it yourself"). The literacy of the patient safety educational materials was analyzed using a paired t-test with a p value of 0.05. The comparison between patient safety literacy on pre- and post-tests revealed that among all participants, there were significant differences in "easy to understand," "help in safe hospitalization," and "do it yourself" scores. To improve patient safety literacy, patient education materials need to optimize communication by improving patients' knowledge, skills, and attitudes for maintaining and promoting healthy living.

BACKGROUND: Given the association between geriatric syndrome and hospital readmission, we evaluated the suitability of geriatric syndrome screening for care (GSC) in identifying readmission risk and suggested the appropriate time for GSC. METHODS: GSC considering cognitive impairment, depression, polypharmacy (five or more medications), functional mobility, dysphagia, malnutrition, pain, and incontinence was performed among 2,663 general ward inpatients aged 65 years or older within 48 hours after admission and again before discharge between November 2016 and October 2017. From each patient, fall events, pressure ulcers, potentially inappropriate medication use, and delirium were assessed at admission. Patients were divided into two groups on the basis of readmission within 1 year after the first admission. According to the screening period (at admission and before discharge) and in-hospital decline, we applied receiver operating characteristic curve analysis to compare the prevalence of clinical concerns between the readmission and no-readmission groups. We also used multiple logistic regression analysis to evaluate the risk of readmission according to the presence of geriatric syndrome and clinical outcomes. RESULTS: The 782 readmitted patients (29.4%) showed a higher rate of poor GSC than those who were not readmitted. Polypharmacy at admission was significantly correlated with readmission risk (area under the receiver operating characteristic curve=0.602). Fall events (odds ratio [OR]=4.36; 95% confidence interval [CI], 2.36-8.05), urinary incontinence (OR=4.21; 95% CI, 3.28-5.39), and depressive mood (OR=3.88; 95% CI, 2.69-5.59) at admission were risk factors for readmission. CONCLUSION: Geriatric syndromes assessed by GSC at admission was associated with an increased risk of readmission.
RESUMO
Methylglyoxal (MGO), a reactive carbonyl species, causes cellular damage and is closely related to kidney disease, particularly diabetic nephropathy. Although MGO has been reported to induce autophagy and apoptosis, the relationships between the two pathways are unclear. Here, we evaluated whether autophagy may be the underlying mechanism inhibiting MGO-induced apoptosis. MGO treatment induced concentration- and time-dependent apoptosis in HK-2 cells. Moreover, MGO upregulated the autophagy markers p62 and LC3-II. Apoptosis caused by MGO was increased in ATG5-knockdown cells compared to that in wild-type cells. In contrast, autophagy activation by 5-aminoimidazole-4-carboxamide ribonucleotide resulted in reduced apoptosis, suggesting that autophagy played a role in protecting against MGO-induced cell death. To examine the mechanisms through which autophagy occurred following MGO stimulation, we investigated changes in AKT/mammalian target of rapamycin (mTOR) signaling. Autophagy induction by MGO treatment was not related to AKT/mTOR signaling; however, it did involve autophagy-related gene expression promoted by AMP-activated protein kinase-mediated transcription factors, such as forkhead box 1. Overall, our findings indicate that MGO-induced cellular damage can be mitigated by autophagy, suggesting that autophagy may be a potential therapeutic target for diseases such as diabetic nephropathy.

Persistent infection with high-risk strains of human papillomavirus (HPV) is the primary cause of cervical cancer, the fourth most common cancer among women worldwide. Two oncoproteins encoded by the HPV genome, E6 and E7, are required for epigenetic modifications that promote cervical cancer development. We found that knockdown of HPV E6/E7 by siRNA reduced the levels of ubiquitin-like containing PHD and RING finger domain 1 (UHRF1) but increased the levels of gelsolin (GSN) in early stage cervical cancer cells. In addition, we found that UHRF1 levels were increased and GSN levels were decreased in early stage cervical cancer compared with those in normal cervical tissues, as shown by Western blot analysis, immunohistochemistry, and analysis of the Oncomine database. Moreover, knockdown of UHRF1 resulted in increased cell death in cervical cancer cell lines. Treatment of E6/E7-transformed HaCaT (HEK001) cells and HeLa cells with the DNA-hypomethylating agent 5-aza-2'-deoxycytidine and the histone deacetylase inhibitor Trichostatin A increased GSN expression levels. UHRF1 knockdown in HEK001 cells by siRNA or the UHRF1 antagonist thymoquinone increased GSN levels, induced cell cycle arrest and apoptosis, and increased the levels of p27 and cleaved PARP. Those results indicate that upregulation of UHRF1 by HPV E6/E7 causes GSN silencing and a reduction of cell death in early stage cervical cancer, suggesting that GSN might be a useful therapeutic target in early stage cervical cancer.

BACKGROUND: This study aims to increase understanding of how patient and family education affects the prevention of medical errors, thereby providing basic data for developing educational contents. METHODS: This descriptive study surveyed patients, families, and Patient Safety Officers to investigate the relationship between educational contents and medical error prevention. The Chi-square test and ANOVA were used to derive the results of this study. The educational contents used in this study consisted of health information (1. current medicines, 2. allergies, 3. health history, 4. previous treatments/tests and complications associated with them) and Speak Up (1. handwashing, 2. patient identification, 3. asking about medical conditions, 4. asking about test results, 5. asking about behaviour and changes in lifestyle, 6. asking about the care plan, 7. asking about medicines, and 8. asking about medicine interactions). RESULTS: In this study, the first criterion for choosing a hospital for treatment in Korea was 'Hospital with a famous doctor' (58.6% patient; 57.7% families). Of the patients and their families surveyed, 82.2% responded that hospitals in Korea were safe. The most common education in hospitals is 'Describe your medical condition', given to 69.0% of patients, and 'Hospitalisation orientation', given to 63.4% of families. The most important factors in preventing patient safety events were statistically significant differences among patients, family members, and Patient Safety Officers (p = 0.001). Patients and families had the highest 'Patient and family participation' (31.0% of patients; 39.4% of families) and Patient Safety Officers had the highest 'Patient safety culture' (47.8%). CONCLUSIONS: Participants thought that educational contents developed through this study could prevent medical errors. The results of this study are expected to provide basic data for national patient safety campaigns and standardised educational content development to prevent medical errors.

BACKGROUND: The 48/6 Model of Care is an integrative care initiative for improving the health outcomes of hospitalized older patients; however, its applicability in community-dwelling older adults as a health screening tool has not been investigated. The present study aimed to examine the applicability of this model, prevalence of dysfunction in 6 care areas, and its relationship with self-reported mobility in community-dwelling older adults. METHODS: This was a cross-sectional survey study of community-dwelling adults aged 65 or older. Participants were screened for problems using 9 items corresponding to the 6 care areas of the 48/6 Model of Care (cognitive functioning, functional mobility, pain management, nutrition and hydration, bladder and bowel management, and medication management). Mobility was assessed via the Life-Space Assessment (LSA). We examined the correlation between each screening item and the LSA. RESULTS: A total of 444 older adults (260 women, 58.6%) participated. The mean number of health problems was 2.3 ± 2.1, with the most common being pain, cognitive impairment, and urinary incontinence. These problems and LSA scores were significantly different by age groups. A multiple regression analysis showed that polypharmacy (ß = -10.567, P < 0.001), dysphagia (ß = -9.610, P = 0.021), and pain (ß = -7.369, P = 0.004) were significantly associated with life-space mobility after controlling for age. CONCLUSION: The 48/6 Model of Care is applicable to community-dwelling older adults, who show high prevalence of dysfunction in the 6 care areas. This study supports the role of the model in screening for the health status of older adults living in the community, and in estimating mobility.

BACKGROUND: In the age of aging, Korea's current medical delivery system threatens to increase the number of medical and caring refugees. This study attempts to develop an integrated senior citizen-oriented healthcare service system in which daily care, professional care, and rehabilitation are organically organized between medical institutions and local communities, thereby meeting the daily life needs of the elderly and inducing well-being, wellness, and well-dying. METHODS: To develop the integrated healthcare system, data collection and analyses were conducted through a systematic review, literature review, benchmarking, focus group interviews, and expert consultation. RESULTS: The senior-specific, citizen-oriented healthcare service system developed in this study is designed to screen patients aged 65 or older within 24 h of being admitted, using the Geriatric Screening for Care-10. If there is reason for concern as a result of the screening, further evaluation is performed through assessment. Doctors and nurses create a care plan and a discharge plan based on the results from the screening and assessment. The nurse further uses the screening to monitor the patient's condition before discharge. Based on the screening results at the time of discharge, a transitional care plan is prepared and provided to elderly patients and/or their families. This process enables a systematic link between medical institutions and community resources, aiming for the continuous management of health issues. It also establishes a multidisciplinary treatment plan that considers patients and their families so that diseases common to the elderly are diagnosed and treated promptly. CONCLUSIONS: The most important issue for the elderly is to be able to live healthily and independently for the rest of their lives through well-being, wellness, and well-dying. The senior-specific, citizen-oriented healthcare service proposed in this study is an integrated medical treatment system for elderly users the implementation of which requires the daily care, professional care, and rehabilitation of elderly members of society to be organically organized according to the role of the patients, their families, and the caregiver.

Metformin is a widely used drug for the treatment of type 2 diabetes. Antidiabetic drugs are also known to influence cancer progression, as high glucose levels affect both cancer and diabetes. Metformin induces cell cycle arrest in cancer cells, but the underlying mechanism remains unclear in cervical cancer system. Here, we examined how metformin affects cell cycle arrest and apoptosis in cervical cancer cells. Western blot analysis showed that levels of O-linked N-acetylglucosamine (O-GlcNAc) and O-GlcNAc transferase (OGT) were increased in cervical cancer cells; these effects were reversed by metformin treatment. Immunoprecipitation analysis was used to examine the interplay between O-GlcNAcylation and phosphorylation in HeLa cells, revealing that metformin decreased O-GlcNAcylated AMP-activated protein kinase (AMPK) and increased levels of phospho-AMPK compared to untreated cells. These results were associated with decreased cell cycle arrest and apoptotic cell death in HeLa cells, as shown by flow cytometry. Moreover, 6-diazo-5-oxo-L-norleucine (a glutamine fructose-6-phosphate aminotransferase inhibitor) or thiamet G (an O-GlcNAcase inhibitor) decreased or increased levels of O-GlcNAcylated AMPK, and increased or decreased levels of phosphorylated AMPK, respectively, suggesting that O-GlcNAc modification affects AMPK activation. Of note, we found that metformin treatment of HeLa cells increased the levels of p21 and p27 (which are AMPK-dependent cell cycle inhibitors), leading to increased cell cycle arrest and apoptosis in HeLa cells compared to untreated cells. These findings suggest that metformin may serve as a useful antiproliferative drug in cervical cancer cells, with potential therapeutic benefit.
RESUMO
OBJECTIVE: The aim of the study was to identify the risk factors for mobility decline among hospitalized older patients early. DESIGN: This is a prospective cohort study. A total of 875 older patients were divided into two groups: older patients with and without mobility decline. The mobility level was measured using the item of functional mobility in the Geriatric Screening for Care 10. The change in mobility between admission and discharge was determined as the dependent variable. There were a total of 18 independent variables, which consisted of three demographic variables, 10 most problematic domains of geriatric care, and five other health-related variables. A multivariable logistic regression analysis was conducted to identify the risk factors for mobility decline during hospitalization. RESULTS: Of the 875 older patients, 135 (15.4%) experienced mobility decline during hospitalization. The multivariable logistic regression analysis revealed female sex, cognitive impairment, and underweight as the risk factors for mobility decline during hospitalization. CONCLUSIONS: The identified risk factors should be considered to identify patients at a risk of mobility decline early and to provide targeted interventions, which can prevent mobility decline.

PURPOSE: The early detection of dysphagia, a common clinical issue among older adults, is important. However, healthcare professionals sometimes experience difficulties in applying the current screening tools to older adults. Therefore, we developed the Easy Dysphagia Symptom Questionnaire (EDSQ), a simplified tool for the older adults, and investigated its reliability and validity. METHODS: The 12-item "yes/no" EDSQ assesses dysphagia symptoms, with a total score being the sum of all "yes" responses. Each item was determined by consensus of three physiatrists after reviewing the previous dysphagia questionnaires. Participants were aged 65 years or older who either complained of or were suspected by a physician of facing swallowing disturbance. They completed the EDSQ, modified water swallow test (MWST), and videofluoroscopic swallowing study. The EDSQ's internal consistency was assessed. Correlations between the EDSQ total score and the MWST, American Speech-Language-Hearing Association's National Outcome Measurement System (ASHA NOMS) swallowing scale, and videofluoroscopic dysphagia scale (VDS) were analyzed. RESULTS: The sample comprised 51 participants (29 male, 56.9%; mean age 76.7 ± 6.6 years). Mean EDSQ total score was 4.33 ± 3.03 (range 0-12). Regarding the EDSQ's reliability, the Cronbach's α coefficient was 0.785. The EDSQ total score correlated with the MWST (r = - 0.468, p = 0.001), ASHA NOMS swallowing scale (r = - 0.635, p < 0.001), and VDS (r = 0.449, p = 0.001). The receiver-operating characteristic analysis revealed an optimal cut-off score of ≥ 5, with a sensitivity of 90.9% and a specificity of 67.5%. CONCLUSIONS: The EDSQ showed acceptable reliability and validity, indicating its applicability to older adults as a simple screening tool for safe swallowing.
RESUMO
AIM AND OBJECTIVES: To provide basic information on the preventive care for pressure ulcer (PU) by analysing PU-related characteristics and identifying PU predictors. BACKGROUND: The incidence of PUs in hospitals is increasing, and continuous PU management is required. The occurrence of PU was an important standard for hospital certification. There is a need to identify predictors of PUs for proper management of PUs. DESIGN: This is a descriptive study that analyses the electronic medical records of a university hospital. METHODS: Of all older adult inpatients aged over 65 years admitted to the hospital (from January 1, 2011-December 31, 2015), 34,287 were included in this study. To identify the PU predictors, a logistic regression analysis was performed using IBM SPSS Statistics 24. RESULTS: Predictors influencing PU were gender (OR = 1.36, 95% CI = 1.03-1.05), age, (OR = 1.04, 95% CI = 1.03-1.05), admission method (OR = 0.39, 95% CI = 0.32-0.46), consciousness status (OR = 3.77, 95% CI = 1.83-7.77) and Braden Scale score (OR = 0.07, 95% CI = 0.69-0.72). Among the predictors, consciousness is the most important variable. Patients who are drowsy were 3.77 times more likely to develop PU than those who are alert. CONCLUSIONS: To prevent and manage PU, the level of consciousness of older adult patients who are hospitalised should be assessed, and appropriate interventions should be provided. RELEVANCE TO CLINICAL PRACTICE: Pressure ulcer-specific interventions should be provided systematically by healthcare providers to those with altered consciousness beginning at hospital admission.

Oxidative stress plays an important role in the development of diabetic retinopathy. Here, we examined whether α-lipoic acid (α-LA), a natural antioxidant, attenuated retinal injury in diabetic mice. The α-LA was orally administered to control mice or mice with streptozotocin-induced diabetes. We found that α-LA reduced oxidative stress, decreased and increased retinal 4-hydroxy-2-nonenal and glutathione peroxidase, respectively, and inhibited retinal cell death. Concomitantly, α-LA reversed the decreased activation of AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase, and increased the levels of peroxisome proliferator-activated receptor delta and sirtuin3 in diabetic mouse retinas, similar to results shown after metformin treatment of retinal pigment epithelial cells (RPE) exposed to high glucose. Moreover, α-LA lowered the levels of O-linked ß-N-acetylglucosamine transferase (OGT) and thioredoxin-interacting protein (TXNIP) in diabetic retinas that were more pronounced after metformin treatment of RPE cells. Importantly, α-LA lowered interactions between AMPK and OGT as shown by co-immunoprecipitation analyses, and this was accompanied by less cell death as measured by double immunofluorescence staining by terminal deoxynucleotide transferase-mediated dUTP nick-end labelling and OGT or TXNIP in retinal ganglion cells. Consistently, α-LA lowered the levels of cleaved poly(ADP-ribose) polymerase and pro-apoptotic marker cleaved caspase-3 in diabetic retinas. Our results indicated that α-LA reduced retinal cell death partly through AMPK activation or OGT inhibition in diabetic mice.

BACKGROUND: Elderly people often have more complicated healthcare needs than younger adults due to additional functional decline, physical illness, and psychosocial needs. Unmet healthcare needs increase illness severity, complications, and mortality. Despite this, research on the unmet healthcare needs of elderly people is limited in Korea. This study analysed the effect of functional deterioration related to aging on unmet healthcare needs based on the Korea Health Panel Study. METHODS: This cross-sectional study used data from the 2011-2013 survey of 8666 baseline participants aged 65 years and older. Unmet healthcare needs were calculated using a complex weighted sample design. Group differences in categorical variables were analysed using the Rao-Scott Chi-square test. Using logistic regression analysis, the association between unmet healthcare needs and aging factors was analysed. RESULTS: The prevalence of unmet healthcare needs in Korean elderly was 17.4%. Among them, the leading reason was economic hardship (9.2%). Adjusting for sex, age, socioeconomic characteristics, and health-related characteristics, the group with depression syndrome was 1.45 times more likely to have unmet healthcare needs than that without depression syndrome (95% CI = 1.13-1.88). The group with visual impairment was 1.48 times more likely to have unmet healthcare needs than that without it (95% CI = 1.22-1.79). The group with hearing impairment was 1.40 times more likely to have unmet healthcare needs than that without it (95% CI = 1.15-1.72). The group with memory impairment was 1.74 times more likely to have unmet healthcare needs than that without it (95% CI = 1.28-2.36). CONCLUSIONS: The unmet medical needs of the elderly are more diverse than those of younger adults. This is because not only socioeconomic and health-related factors but also aging factors that are important to the health of the elderly are included. All factors were linked organically; therefore, integrated care is needed to improve healthcare among the elderly. To resolve these unmet healthcare needs, it is necessary to reorganize the healthcare system in Korea to include preventive and rehabilitative services that address chronic diseases in an aged society and promote life-long health promotion.

O-linked N-acetylglucosamine transferase (OGT) expression is increased in various cancer types, indicating the potential importance of O-GlcNAcylation in tumorigenesis. Secretory clusterin (sCLU) is involved in cancer cell proliferation and drug resistance, and recently, liver X receptors (LXRs) and sterol response element binding protein-1 (SREBP-1) were reported to regulate sCLU transcription. Here, we found that sCLU is significantly increased in cervical cancer cell lines, which have higher expression levels of O-GlcNAc and OGT than keratinocytes. OGT knockdown decreased expression of LXRs, SREBP-1 and sCLU through hypo-O-GlcNAcylation of LXRs. Additionally, treatment with Thiamet G, O-GlcNAcase OGA inhibitor, increased expression of O-GlcNAcylation and sCLU, and high glucose increased levels of LXRs, SREBP-1 and sCLU in HeLa cells. Moreover, OGT knockdown induced G0/G1 phase cell cycle arrest and late apoptosis in cisplatin-treated HeLa cells, and decreased viability compared to OGT intact HeLa cells. Taken together, these findings suggest that OGT, O-GlcNAcylated LXRs, and SREBP-1 increase sCLU expression in cervical cancer cells, which contributes to drug resistance.
RESUMO
PURPOSE: This study aimed to analyze the demographic characteristics associated with vitamin D deficiency, as well as the association between vitamin D deficiency and metabolic syndrome, among Korean adolescents. DESIGN AND METHODS: This cross-sectional descriptive study involved 2314 adolescents aged 12-18years. Participant data were extracted from the Korean National Health and Nutrition Examination Survey conducted between January 2010 and December 2014. A logistic regression analysis was performed to analyze the association between vitamin D and metabolic syndrome. All analyses were performed using IBM SPSS Statistics 24. RESULTS: Among the participants, 78% exhibited vitamin D deficiency and 7.8% had metabolic syndrome. The vitamin D deficient and sufficient groups differed significantly in terms of age, sex, household income, and self-perceived health status. Among the subcomponents of metabolic syndrome, vitamin D deficiency was associated with a 2.07-fold higher risk of elevated fasting blood glucose (≥100mg/dL). CONCLUSIONS: The association of vitamin D deficiency with an increased risk of elevated fasting blood glucose levels suggests that adolescents in this population should receive interventions to prevent and manage diabetes. In the future, the effects of vitamin D deficiency on chronic health problems, including diabetes, should be investigated in adolescents. PRACTICE IMPLICATIONS: Adolescents with vitamin D deficiency should be screened for prediabetes, and clinicians should be concerned about both the diagnosis and prevention of diabetes in this population.
