RESUMEN
BACKGROUND: Polypharmacy is a global public health concern. This study aimed to determine the prevalence of polypharmacy and trends in the use of commonly used and potentially inappropriate medications among older Korean patients. METHODS: Individuals aged ≥ 65 years who were prescribed any medication between 2014 and 2018 were selected from the Korean National Health Information Database. Joinpoint regression analyses were used to determine trends in the age-adjusted polypharmacy rates by age group. The prescription rates of the most commonly used medications and the most commonly used potentially inappropriate medications were analysed by year or age group for patients with polypharmacy using the chi-square and proportion difference tests. RESULTS: This study included 1,849,968 patients, 661,206 (35.7%) of whom had polypharmacy. Age-adjusted polypharmacy rates increased significantly between 2014 and 2018 (P = 0.046). Among patients with polypharmacy, the most commonly prescribed medications were aspirin (100 mg), atorvastatin, metformin, glimepiride, and rosuvastatin. The most commonly prescribed and potentially inappropriate medications were alprazolam, diazepam, amitriptyline, zolpidem, and dimenhydrinate. There was a significant decrease in the prescription rates for each of these drugs in 2018 compared with 2014 among patients with polypharmacy (all P < 0.001), whereas there was a significant increase in alprazolam prescription among patients aged ≥ 85 years when analysed by age group (P < 0.001). CONCLUSIONS: This study revealed an increasing prevalence of polypharmacy among older adults. Additionally, it highlighted that the utilisation of commonly prescribed potentially inappropriate medications, such as benzodiazepines and tricyclic antidepressants, has remained persistent, particularly among patients aged ≥ 85 years who practiced polypharmacy. These findings provide evidence-based guidance for the development of robust polypharmacy management strategies to ensure medication safety among older adults.

OBJECTIVE: We sought to investigate the biological effects of pre-reperfusion treatments of the liver after warm and cold ischemic injuries in a porcine donation after circulatory death model. SUMMARY OF BACKGROUND DATA: Donation after circulatory death represents a severe form of liver ischemia and reperfusion injury that has a profound impact on graft function after liver transplantation. METHODS: Twenty donor pig livers underwent 60 minutes of in situ warm ischemia after circulatory arrest and 120 minutes of cold static preservation prior to simulated transplantation using an ex vivo perfusion machine. Four reperfusion treatments were compared: Control-Normothermic (N), Control- Subnormothermic (S), regulated hepatic reperfusion (RHR)-N, and RHR-S (n = 5 each). The biochemical, metabolic, and transcriptomic profiles, as well as mitochondrial function were analyzed. RESULTS: Compared to the other groups, RHR-S treated group showed significantly lower post-reperfusion aspartate aminotransferase levels in the reperfusion effluent and histologic findings of hepatocyte viability and lesser degree of congestion and necrosis. RHR-S resulted in a significantly higher mitochondrial respiratory control index and calcium retention capacity. Transcriptomic profile analysis showed that treatment with RHR-S activated cell survival and viability, cellular homeostasis as well as other biological functions involved in tissue repair such as cytoskeleton or cytoplasm organization, cell migration, transcription, and microtubule dynamics. Furthermore, RHR-S inhibited organismal death, morbidity and mortality, necrosis, and apoptosis. CONCLUSION: Subnormothermic RHR mitigates IRI and preserves hepatic mitochondrial function after warm and cold hepatic ischemia. This organ resuscitative therapy may also trigger the activation of protective genes against IRI. Sub- normothermic RHR has potential applicability to clinical liver transplantation.

Mixed hepatocellular carcinoma with neuroendocrine carcinoma (HCC-NEC) is extremely rare, comprising about 0.46% of primary hepatic tumors. A 63-year-old man who was a chronic alcoholic presented with a nine-centimeter-sized hepatic mass. His serum alpha-fetoprotein and protein induced by vitamin K antagonist-II levels were 22,815 ng/mL and 183 mAU/mL, respectively. The patient underwent a right hemihepatectomy, including the middle hepatic vein. The tumor consisted of poorly differentiated HCC (20%) and large- and small-cell-type NEC (80%) components as per the pathological examination. Immunohistochemically chromogranin and synaptophysin were positive in the areas of NEC and negative in the areas of HCC. Adjuvant chemotherapy with a combination of cisplatin and etoposide was administered after surgery. At postoperative 5 months, the patient complained of right flank pain, and CT showed a new mass measuring 7.3 cm in the right adrenal gland. Postoperatively, after 6.5 months, more recurred masses were noted on the posterior aspect of the right kidney and both lungs. Although the regimen was changed from etoposide to irinotecan, additional recurred masses were developed in the liver, lung, and brain. He passed away 12 months after the surgery. After reviewing and analyzing previous literature, the 1 and 2 year overall survival rates are 57.3 and 43.6%, respectively, and the 1 and 2 year disease-free survival rates are 36.2 and 29.0%, respectively. Mixed HCC-NEC is a very rare tumor, and the surgical outcome is poor.

Background and Objectives: The COVID-19 pandemic has brought serious changes in healthcare systems worldwide, some of which have affected patients who need emergency surgery. Acute appendicitis is the most common surgical disease requiring emergency surgery. This study was performed to determine how the COVID-19 pandemic has changed the treatment of patients with acute appendicitis in South Korea. Materials and Methods: We retrospectively reviewed a medical database that included patients who underwent surgery for acute appendicitis in our hospital from January 2019 to May 2021. We classified the patients into two groups according to whether they were treated before or after the COVID pandemic and 10 March 2020 was used as the cutoff date, which is when the World Health Organization declared the COVID pandemic. Results: A total of 444 patients were included in the "Pre-COVID-19" group and 393 patients were included in the "COVID-19" group. In the "COVID-19" group, the proportion of patients with severe morbidity was significantly lower. The time that the patients spent in the emergency room before surgery was significantly longer in the "COVID-19" group (519.11 ± 486.57 min vs. 705.27 ± 512.59 min; p-value < 0.001). There was no difference observed in the severity of appendicitis or in the extent of surgery between the two groups. Conclusions: During the COVID-19 pandemic, a statistically significant time delay (186.16 min) was needed to confirm COVID-19 infection status. However, there was no clinical difference in the severity of appendicitis or in the extent of surgery. To ensure the safety of patients and medical staff, a COVID-19 PCR test should be performed.

BACKGROUND: Ambient fine particulate matter is a rising concern for global public health. It was recently suggested that exposure to fine particulate matter may contribute to the development of diabetes and dyslipidaemia. This study aims to examine the potential associations of ambient particulate matter exposure with changes in fasting glucose and lipid profiles in Koreans. METHOD: We used the data from the National Health Insurance Service-National Sample Cohort (NHIS-NSC), a nationwide database representative of the Korean population. A total of 85,869 individuals aged ≥20 years were included. Multiple regression analyses were conducted to assess the associations between exposure to particulate matter and changes in fasting glucose and lipid profiles at 2-year intervals after adjusting for confounders. RESULTS: Significant associations were observed between an increase in interquartile range for particulate matter < 2.5 µm in diameter (PM2.5) and elevated levels of fasting glucose and low-density lipoprotein cholesterol (p for trend = 0.015 and 0.010, respectively), while no association for particulate matter sized 2.5-10 µm in diameter (PM10-2.5) was noted after adjusting for the other covariates. Sub-group analyses showed stronger associations in individuals who were older (≥60 years) or physically inactive. CONCLUSIONS: Fine particulate matter exposure affects worsening fasting glucose and low-density lipoprotein cholesterol levels, with no evidence of an association for coarse particulate matter.

BACKGROUND AND OBJECTIVES: Metabolic syndrome is a leading global public health concern. Nutritional approaches are important for preventing and managing cardiometabolic risks, including metabolic syndrome. The aim of this study was to examine the potential association between riboflavin intake and cardiometabolic risks according to sex among Koreans. METHODS AND STUDY DESIGN: We used data from the Korea National Health and Nutrition Examination Survey 2015-2016, a nationwide cross-sectional survey that assesses the health and nutritional status of the Korean population. A total of 6,062 individuals aged ≥19 years were included. The nutrition survey was performed using 24-h dietary recall. RESULTS: A significant association was observed between low riboflavin intake with only increased HDL-cholesterol (OR 1.362, 95% CI 1.017-1.824, p=0.038) among metabolic syndrome and its components in men, whereas insufficient riboflavin intake was positively associated with hypertension (OR 1.352, 95% CI 1.085-1.685, p=0.007), diabetes (OR 1.493, 95% CI 1.137-1.959, p=0.004) and metabolic syndrome (OR 1.289, 95% CI 1.014-1.640, p=0.038) in women after adjusting for the other covariates. For post-menopausal women, central obesity was also correlated with insufficient riboflavin intake (OR 1.315, 95% CI 1.019-1.696, p=0.035). CONCLUSIONS: Insufficient riboflavin intake may contribute to development of cardiometabolic disorder, particularly in women. It was also found that riboflavin may have different influences on its risks in women according to menopausal status. This study highlighted the importance of public policies targeted at these sex-specific groups for reducing cardiometabolic risks.

BACKGROUND: The goal of this study was to analyze the relationship between exercise frequency and all-cause mortality for individuals diagnosed with and without diabetes mellitus (DM). METHODS: We analyzed data for 505,677 participants (53.9% men) in the National Health Insurance Service-National Health Screening (NHIS-HEALS) cohort. The study endpoint variable was all-cause mortality. RESULTS: Frequency of exercise and covariates including age, sex, smoking status, household income, blood pressure, fasting glucose, body mass index, total cholesterol, and Charlson comorbidity index were determined at baseline. Cox proportional hazard regression models were developed to assess the effects of exercise frequency (0, 1-2, 3-4, 5-6, and 7 days per week) on mortality, separately in individuals with and without DM. We found a U-shaped association between exercise frequency and mortality in individuals with and without DM. However, the frequency of exercise associated with the lowest risk of all-cause mortality was 3-4 times per week (hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.65-0.73) in individuals without DM, and 5-6 times per week in those with DM (HR, 0.93; 95% CI, 0.78-1.10). CONCLUSION: A moderate frequency of exercise may reduce mortality regardless of the presence or absence of DM; however, when compared to those without the condition, people with DM may need to exercise more often.

BACKGROUND: We intended to determine the usefulness of gadoxetic acid-enhanced magnetic resonance (MR) imaging on preoperative prediction of the risk of postoperative liver failure (PLF) using measurement of relative liver enhancement (RLE) in patients who underwent surgical resection of hepatocellular carcinoma (HCC). METHODS: A total of 121 HCC patients who had underwent gadoxetic acid-enhanced MRI before surgery between January 2012 and April 2015 at our hospital was retrospectively analyzed. RLE was calculated as the ratio of signal intensity measurements of the liver parenchyma in each liver segment before and 20 min after intravenous administration of gadoxetic acid. PLF was defined based on the "50-50 criteria" (prothrombin time <50% and serum bilirubin >5 mg/dL on 5 days after surgery). RESULTS: Of the 121 patients, 74 (61.2%) patients had liver cirrhosis, clinically. Median tumor size 2.8 cm (range, 1-14 cm), 106 (87.6%) patients had a single HCC, and 101 (83.5%) patients had HCC within Milan criteria. Based on the "50-50 criteria", PLF was observed in 7 (5.8%) patients. Mean RLE was significantly lower in patients with PLF than those without it (55.9% vs 85.5%, P < 0.01). In a multivariate analysis, decreased RLE was a significant independent risk factor for PLF in HCC patients (odds ratio 0.97, P = 0.03). Optimal cut-off RLE value was 82.36. CONCLUSIONS: RLE was significantly lower in patients with PLF than those without it. Measurement of RLE using gadoxetic acid-enhanced MR imaging before surgery can be useful for prediction of PLF in HCC patients who receive surgical treatment.

Streptochlorin, a small compound derived from marine actinomycete, has been shown to have anti-angiogenic, anti-tumor, and anti-allergic activities. However, the anti-inflammatory effects and underlying mechanisms have not yet been reported. In the present study, we investigated the effect of streptochlorin on lipopolysaccharide (LPS)-induced inflammatory responses in vitro and in vivo. Streptochlorin attenuated the production of proinflammatory mediators such as nitric oxide, cyclooxygenase-2, pro-interleukin (IL)-1ß, and IL-6 in LPS-stimulated RAW264.7 cells through inhibition of the Toll/interleukin-1 receptor (TIR)-domain-containing adapter-inducing interferon-ß (TRIF)-dependent signaling pathway. Furthermore, streptochlorin suppressed the infiltration of immune cells such as neutrophils into the lung and proinflammatory cytokine production such as IL-6 and TNF-α in broncho-alveolar lavage fluid (BALF) in the LPS-induced acute lung injury (ALI) mouse model. Streptochlorin has potent anti-inflammatory effects through regulating TRIF-dependent signaling pathways, suggesting that streptochlorin may provide a valuable therapeutic strategy in treating various inflammatory diseases.

Emodin, an active constituent of oriental herbs, is widely used to treat allergy, inflammation, and other symptoms. This study provides the scientific basis for the anti-inflammasome effects of emodin on both in vitro and in vivo experimental models. Bone marrow-derived macrophages were used to study the effects of emodin on inflammasome activation by using inflammasome inducers such as ATP, nigericin, and silica crystals. The lipopolysaccharide (LPS)-induced endotoxin shock model was employed to study the effect of emodin on in vivo efficacy. Emodin treatment attenuated interleukin (IL)-1ß secretion via the inhibition of NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome activation induced by ATP, nigericin, and silica crystals. Further, emodin ameliorated the severity of NLRP3 inflammasome-mediated symptoms in LPS-induced endotoxin mouse models. This study is the first to reveal mechanism-based evidence, especially with respect to regulation of inflammasome activation, substantiating traditional claims of emodin in the treatment of inflammation-related disorders.

BACKGROUND/AIMS: Microvascular invasion (MVI) is a well-known prognostic factor of postoperative recurrence and of overall survival (OS) in patients with hepatocellular carcinoma (HCC). We compared the treatment outcomes of transarterial chemoembolization (TACE) and surgery/radiofrequency ablation (RFA) according to the presence of MVI in patients with early or late recurrent HCC that presented as Barcelona Clinical Liver Cancer (BCLC) stage 0 or A after curative resection for HCC. METHODS: A consecutive 68 patients with recurrent HCC of BCLC stage 0 or A at our institution between 1998 and 2012 were retrospectively enrolled. We compared the outcomes of patients treated by TACE or surgery/RFA. Tumor recurrence after curative resection was classified as early (≤ 12 months) or late (> 12 months) recurrence. RESULTS: Median tumor size was 1.5 cm (range, 1-10 cm), and 67 (98.5%) had HCCs within the Milan criteria. Median post-retreatment follow-up duration was 27 months (range, 1-109 months). Of the 68 patients, 19 (27.9%) underwent surgery/RFA, 47 (69.1%) TACE, and 2 (2.9%) were lost to follow-up. After retreatment, TACE showed significantly higher OS and recurrence-free survival rates than surgery/RFA in MVI-positive patients (P = 0.03 and P = 0.05, respectively), but not in MVI-negative patients (P = 0.95 and P = 0.98, respectively). In particular, in early recurred MVI-positive patients, TACE had a significantly higher OS rate than surgery/RFA (P = 0.01). CONCLUSIONS: TACE may be the more effective treatment option for recurrent HCC of BCLC stage 0 or A than surgery/RFA in MVI-positive patients, especially in those that recur early after curative resection.

PURPOSE: The evolution of splenomegaly in patients with liver cirrhosis remains largely unknown. In this study, we followed the changes in splenic volume and established the natural course of splenomegaly. We developed an electronic circuit that simulated splenoportal circulation and identified the underlying hemodynamic mechanisms. MATERIALS AND METHODS: This retrospective observational study included 93 patients with cirrhosis. Splenic volumes were measured in imaging studies at 6-month intervals and normalized by the ratio of each patient's maximum volume during follow-up (%Vmax). An electronic simulation model was constructed using software and realized on a breadboard. RESULTS: Overall, the %Vmax increased from 0.77 â± â0.21 to a maximum of 1.00 â± â0.00 (p â< â0.001) during a median follow-up of 23 (3-162) months and then decreased to 0.84 â± â0.18 (p â< â0.001) during the next 9 (3-132) months. No interventional radiology procedure was performed to improve hepatic fibrosis and portal hypertension. The evolution of %Vmax showed single-peaked symmetry. An electronic simulation model showed that the upslope of the evolution curve was dependent on the increased intrahepatic vascular resistance and portal hypertension, whereas the downslope was dependent on the decreased portosystemic shunt (PSS) resistance. CONCLUSIONS: Splenomegaly in cirrhotic patients aggravated over a period of 23 months and then regressed spontaneously to its initial volume. Electronic simulation of splenoportal circulation showed that splenic enlargement was due to the advancement of liver cirrhosis and portal hypertension, whereas its regression was due to the development of a PSS.
RESUMEN
The progression of non-alcoholic fatty liver disease (NAFLD), the most common liver disease, leads to non-alcoholic steatohepatitis and hepatocellular carcinoma. Despite the increasing incidence and prevalence of NAFLD, its therapeutic and preventive strategies to lower the disease burden is limited. In recent years, immunotherapy, including anti-programmed cell death 1/programmed cell death 1 ligand 1 treatment, has emerged as a potential approach to reach satisfactory modulation for the progression of NAFLD and treatment of NAFLD-related hepatocellular carcinoma. However, the effectiveness of immunotherapy against NAFLD and NAFLD-related hepatocellular carcinoma is in the early phase and it is yet not advanced. In addition, conflicting results are being reported regarding the prognosis of patients with NAFLD-related hepatocellular carcinoma and high expression of programmed cell death 1/programmed cell death 1 ligand 1. Herein, this review will discuss and elucidate the attempts and underlying mechanisms of immunotherapy against NAFLD and NAFLD-related hepatocellular carcinoma.

BACKGROUND: Cilostazol is the only first-line medication for treating intermittent claudication, and the controlled-release (CR) formulation is associated with a lower prevalence of adverse events (AEs). OBJECTIVE: The objective of the study was to assess the safety and effectiveness of cilostazol CR in patients with symptomatic peripheral artery disease (PAD). METHODS: In this multicentre (113 sites), open-label, prospective observational study, we evaluated the real-world safety and effectiveness of cilostazol CR 200 mg once daily in patients with symptomatic PAD treated in routine clinical settings. The primary endpoint was the incidence and severity of AEs, and their causal relationship with cilostazol CR. The secondary endpoint was the effectiveness of the drug, as assessed by each patient's physician, for improving intermittent claudication. RESULTS: Among 2063 participants who received cilostazol CR for a mean duration of 88.6 days, 99 (4.80 %) experienced adverse drug reactions (ADRs), although no unexpected adverse reactions were observed. There was no significant difference in the incidence of ADRs according to patient demographics and comorbidities (all p > 0.05). The treatment was 'effective' in 1600 patients (78.93 %), although effectiveness significantly differed according to the patients' sex and the presence of comorbidities, including diabetes mellitus, hypertension, and coronary artery disease (all p < 0.01). CONCLUSIONS: This study demonstrated the tolerability and effectiveness of cilostazol CR treatment in patients with symptomatic PAD.

BACKGROUND/OBJECTIVES: Adequate nutritional intake is essential for good health and well-being. We aimed to compare the nutrient intake from homemade meals, meals sourced externally ("eating out"), and meals from workplace foodservices, as well as the potential association between foodservices used and nutritional quality among adult Korean workers. SUBJECTS/METHODS: We used data from the Korea National Health and Nutrition Examination Survey, a nationwide cross-sectional survey on the health and nutritional status of the Korean population. Data from 6,845 workers aged 20-64 years were included. A survey on dietary behavior and nutrition was conducted using the 24-h dietary recall method. Nutritional quality was examined using the index of nutritional quality (INQ) score. Higher INQ scores reflected poorer nutritional quality, with insufficient intake of a higher number of nutrients. Multivariate linear regression was used to identify the association between the foodservices used and INQ scores after adjusting for other covariates. RESULTS: We found that foodservice users exhibited a higher 1-day intake of total energy and macronutrients (all P < 0.05) and lower INQ scores (P < 0.01) than non-users. The INQ scores for total daily meals decreased with the frequency of foodservice use (P < 0.01). A significant association was observed between the non-use of foodservices and INQ scores (ß = 0.29, P < 0.01) after adjusting for other covariates. CONCLUSIONS: The use of workplace foodservices contributed to higher dietary nutritional quality among workers. This study highlights the importance of expanding the scope of workplace foodservices to promote higher nutritional quality and healthy dietary habits among workers.
RESUMEN
The rates of early gastric cancer and type 2 diabetes mellitus(T2DM) are sharply increasing in Korea. Oncometabolic surgery in which metabolic surgery is conducted along with cancer surgery is a method used to treat gastric cancer and T2DM in one-stage operation. From 2011 to 2019, a total of 48 patients underwent long-limb Roux-en-Y gastrectomy (LRYG) in Inha University Hospital, and all data were reviewed retrospectively. A 75 g oral glucose tolerance test and serum insulin level test were performed before and 1 week and 1 year after surgery. One year after LRYG operation, 25 of 48 patients showed complete or partial remission and 23 patients showed non-remission of T2DM. The preoperative HbA1c level was significantly lower and the change in HbA1c was significantly greater in the T2DM remission group. Insulin secretion indices(insulinogenic index and disposition index) were increased significantly in the T2DM remission group. In contrast, the insulin resistance indices (homeostatic model assessment of insulin resistance (HOMA-IR) and Matsuda index) changed minimal. In the case of LRYG in T2DM patients, remnant ß cell function is an important predictor of favorable glycemic control.

Polypharmacy and its rising global prevalence is a growing public health burden. Using a large representative nationwide Korean cohort (N = 761,145), we conducted a retrospective cross-sectional study aiming to identify subpopulations of patients with polypharmacy and characterize their unique patterns through cluster analysis. Patients aged ≥ 30 years who were prescribed at least one medication between 2014 and 2018 were included in our study. Six clusters were identified: cluster 1 mostly included patients who were hospitalized for a long time (4.3 ± 5.3 days); cluster 2 consisted of patients with disabilities (100.0%) and had the highest mean number of prescription drugs (7.7 ± 2.8 medications); cluster 3 was a group of low-income patients (99.9%); cluster 4 was a group of high-income patients (80.2%) who frequently (46.4 ± 25.9 days) visited hospitals/clinics (7.3 ± 2.7 places); cluster 5 was mostly elderly (74.9 ± 9.8 years) females (80.3%); and cluster 6 comprised mostly middle-aged (56.4 ± 1.5 years) males (88.6%) (all P < 0.001). Patients in clusters 1-5 had more prescribed medications and outpatient visit days than those in cluster 6 (all P < 0.001). Given limited health care resources, individuals with any of the identified phenotypes may be preferential candidates for participation in intervention programs for optimal medication use.

BACKGROUND/AIMS: Advanced hepatocellular carcinoma with either an invasion of the inferior vena cava or thrombosis is rare, and its prognosis is extremely poor. There is no established treatment. The purpose of this study was to evaluate the efficacy of surgical resection and its prognosis in 5 recent cases. METHODOLOGY: From January 2005 to December 2008, 5 patients diagnosed with advanced hepatocellular carcinoma with inferior vena cava invasion and/or thrombosis underwent surgical resection. These patients were retrospectively reviewed. RESULTS: The mean age at diagnosis was 54 years. There were 4 men and 1 woman. According to the Child-Pugh classification, all patients were class A. One case had 2 hepatic masses, and the others had a solitary hepatic mass. The mean tumor size was 5.53cm. All 5 patients underwent partial hepatectomy and inferior vena cava resection or thrombosis removal. Among these, 4 cases needed a cardiopulmonary bypass. Four patients survived and 1 patient expired at the point of analyzing. Four cases experienced recurrences. The mean disease-free survival time was 19.6 months. One patient has been followed-up for 43 months without any recurrences up to now. CONCLUSIONS: Concurrent en-bloc resection of the liver and inferior vena cava for progressive HCC accompanying IVC invasion or thrombosis can be considered as a curative treatment.

This study aimed to determine the potential association between handgrip strength and nutritional quality in Korean men aged ≥20 years using data from the Korea National Health and Nutrition Examination Survey 2016 to 2018. This population-based cross-sectional study included 5,748 men aged ≥20 years. A dietary intake survey was performed using the 24-hr dietary recall method. Nutritional quality was examined using the Index of Nutritional Quality (INQ) score. A high INQ score reflected poor nutritional quality, with insufficient intake of many nutrients. Multivariate linear regression was used to determine the association between handgrip strength and INQ scores after adjusting for other covariates. The intake of carbohydrates, fiber, calcium, and vitamins B2 and C was significantly positively associated with a higher quartile for handgrip strength for those aged ≥65 years (all p < .01). A significant inverse association was found between the quartiles of handgrip strength and INQ scores among men aged ≥65 years after adjusting for all covariates (ß = -0.26, p < .01). This association was not found among those aged <65 years (p = .25). The age-specific association between handgrip strength and nutritional quality underscores the importance of public policies that promote sufficient and comprehensive nutrient intake among older adults. Handgrip strength may be useful in clinical practice as a simple and cost-effective tool for screening for nutritional quality in older adults.

In the current study, we aimed to examine the association between knee pain and diet quality in women aged ≥ 50 years using data from the Korea National Health and Nutrition Examination Survey. This was a population-based, cross-sectional study. Diet quality was assessed using the Diet Quality Index-International (DQI-I), and knee pain and osteoarthritis were self-reported. A multivariate logistic regression model was used to adjust for age, body mass index, household income, marital status, education, occupation, smoking status, hazardous alcohol use, regular physical activity, menopause, and chronic diseases, including hypertension, diabetes, dyslipidemia, osteoarthritis, and depression. A total of 3,881 women were included in this study, and the prevalence of knee pain was 25.4%. The intakes of total energy, protein, and fat were lower in women with knee pain than in those without (all P < 0.01), while the carbohydrate intake was higher (P = 0.01). No significant differences were noted in the scores for variety, overall balance, and moderation components, except for the item of total fat intake, between the DQI-I scores for women with and without knee pain, after adjusting for age. Women without knee pain showed higher scores in several items of the adequacy component (P < 0.05) than did women with knee pain. The total DQI-I scores were lower in women with knee pain than in women without knee pain, after adjusting for covariates, including osteoarthritis (OR = 0.985, 95% CI = 0.973-0.997, P = 0.01). Knee pain independent of osteoarthritis was associated with poor diet quality in community-dwelling women aged ≥ 50 years.
