Glycemic Control and Oral Health Outcomes in Patients With Diabetes: Insights From a Nationwide Korean Survey.

BACKGROUND: Diabetes is recognized as a risk factor for various inflammatory conditions, including periodontitis. There exists a bidirectional relationship between glycemic control and oral health in individuals with diabetes. This study aimed to analyze the link between glycemic control and oral health status among Korean patients with diabetes. METHODS: Using data from a population-based nationwide survey conducted between 2007 and 2019, we identified 70,554 adults with diabetes-related information. The study population included 9,090 individuals diagnosed with diabetes and 61,164 healthy controls. The association between glycemic control, defined by mean glycated hemoglobin (HbA1c) values, and various oral health measures, such as tooth brushing frequency, periodontitis, denture wearing, Decayed, Missing, and Filled Teeth (DMFT) index, number of remaining teeth, and past-year dental clinic visits, was evaluated using multivariate logistic regression analyses. RESULTS: Compared to the control group, patients with diabetes exhibited a higher prevalence of periodontitis (88.6% vs. 73.3%), complete dentures (5.0% vs. 1.5%), and elevated DMFT index (33.2% vs. 26.7%) (all P < 0.001). Multivariate analyses revealed significant associations between diabetes and several oral health factors: denture status (No denture: adjusted odds ratio [aOR], 0.784; 95% confidence interval [CI], 0.627-0.979), and having fewer permanent teeth (0-19) (aOR, 1.474; 95% CI, 1.085-2.003). Additionally, a positive correlation was found between higher HbA1c levels and the risk of having fewer remaining teeth (0-19) (HbA1c < 6.5%: aOR, 1.129; 95% CI, 0.766-1.663; 6.5% ≤ HbA1c < 8.0%: aOR, 1.590; 95% CI, 1.117-2.262; HbA1c ≥ 8%: aOR, 1.910; 95% CI, 1.145-3.186) (P for trends = 0.041). CONCLUSION: We found a positive association between diabetes and poor oral health, as well as a noteworthy relationship between reduced permanent teeth (≤ 19) and glycemic control. These insights emphasize the critical role of oral health management in diabetic care and underscore the importance of maintaining effective glycemic control strategies for overall health and well-being in patients with diabetes.

Nationwide trends in prevalence of underweight, overweight, and obesity among people with disabilities in South Korea from 2008 to 2017.

OBJECTIVES: This study investigated the 10-year trends of weight and prevalence of underweight, overweight and obesity according to disability grade and types compared with those without disabilities. METHODS: This serial cross-sectional analysis was conducted using national disability registration data with national general health checkup data from 2008 to 2017. Age-standardized prevalence of underweight and obesity were analyzed for each year, according to the presence, type, and severity of disabilities. Odds of underweight, overweight, obesity, and severe obesity were examined by multinomial logistic regression after adjusting for socio-demographic and clinical variables using data in 2017. RESULTS: Over 10 million subjects in each year were included in the analysis. In 2017, 14,246,785 people with age between 19 and 110 years were included and 53.1% was men. For 10 years, age-standardized prevalence of obesity and severe obesity showed significant increases regardless of sex and presence of disability. However, age-standardized underweight prevalence in people without disability tended to decrease whereas it was an increase in 2012 and the prevalence has remained steady since in people with disability. People with disabilities had higher odds of underweight compared to those without disability (OR 1.41, 95% CI 1.38-1.44 in male and OR 1.31, 95% CI 1.28-1.34 in female), especially in those with severe disabilities (OR 2.00, 95% CI 1.94-2.06 in male and OR 1.83, 95% CI 1.77-1.89 in female). Women with disabilities are more likely to be obese than those without disabilities regardless of disability severity (OR 1.40, 95% CI 1.38-1.41). Participants with mental disorder showed the highest prevalence of obesity, followed by epilepsy and developmental disability. CONCLUSIONS: Having a disability was associated with higher odds/probability of both obesity and underweight. The intersection of female, severe disability, and mental/developmental disabilities was associated with probability of severe obesity. Simultaneous efforts are needed to develop health policy to reduce both the prevalence of obesity and underweight.

Discussing POLST-facilitated hospice care enrollment in patients with terminal cancer.

PURPOSE: A multicenter prospective study to evaluate the feasibility of Physician Orders for Life-Sustaining Treatment (POLST) in oncology practice was conducted between June and December 2017. Factors associated with POLST completion and follow-up outcomes were analyzed. METHODS: Patients with terminal cancer, aged ≥ 20 years and capable of communicating, were enrolled from seven hospitals. Demographic data were collected and updated in February 2021. Descriptive statistics and logistic regression analyses were conducted. RESULTS: Among 336 patients, 105 (31.3%) completed POLST, which was more common in male (p = 0.029), patients with better performance (p < 0.001), longer duration of follow-up (p = 0.037), and those living with children (p = 0.023). Male (odds ratio [OR], 2.30; 95% confidence interval [CI], 1.17-3.51; p = 0.012), having good performance status (OR, 2.38; 95% CI, (1.35-4.19); p = 0.003), transferred from other departments (OR, 0.50; 95% CI, (0.26-0.98); p = 0.045), and living with children (OR, 1.94; 95% CI, (1.11-3.47); p = 0.020) were significant predictors of POLST completion. Patients who completed POLST were more likely to enroll in hospice care (p = 0.012) or experience out-of-hospital death (p = 0.016) at end-of-life (EOL). POLST completion showed a strong association with hospice enrollment at EOL (OR, 2.61; 95% CI, (1.08-6.32); p = 0.033). CONCLUSION: Gender, patient performance, timing of POLST discussion, and type of household were associated with POLST completion. Earlier discussions on POLST could reinforce hospice enrollment or non-aggressive EOL care.

Clinical efficacy and plausibility of a smartphone-based integrated online real-time diabetes care system via glucose and diet data management: a pilot study.

BACKGROUND: Smartphones have become novel healthcare tools for patients with diabetes. However, it is uncertain whether the smartphone application support system helps in glycaemic control in patients with type 2 diabetes. AIMS: To evaluate the efficacy and plausibility of smartphone-based integrated online real-time diabetes care. METHODS: Forty patients with type 2 diabetes were randomly assigned to the smartphone-based care (SC) (n = 20) and conventional care (CC) (n = 20) groups for 12 weeks. The SC group was instructed to use smartphone application (Noom Coach) and a glucose meter, and was provided medical supervision based on blood glucose level and food intake information sent to the central database server. The efficacy was evaluated by glycated haemoglobin (A1C ≤ 6.5%). The Summary of Diabetes Self-Care Activities (SDSCA) questionnaire was collected at baseline and at week 12. RESULTS: Seventeen and 18 patients of the SC and CC groups completed the study respectively. In the SC group, more patients achieved target A1C compared with the CC group (47.1% vs 11.1%, P = 0.019). In both group, SDSCA scores excluding the exercise item showed overall improvement (general diet, 1.4 ± 2.0 → 2.6 ± 2.3 vs 0.4 ± 1.1 → 1.8 ± 2.2; specific diet, 4.2 ± 1.7 → 5.4 ± 1.2 vs 3.8 ± 1.6 → 5.1 ± 1.1; blood glucose test, 3.3 ± 2.8 → 4.9 ± 2.3 vs 1.0 ± 2.2 → 4.7 ± 2.3; foot care, 1.5 ± 1.6 → 3.6 ± 2.8 vs 1.4 ± 1.9 → 6.1 ± 1.4; all P < 0.05). There was no difference between both groups other than the aspect of foot care (P = 0.008). CONCLUSIONS: The smartphone-based integrated online real-time diabetes care system through glucose and diet data management showed clinical plausibility in glucose control in real clinical practice.

Effectiveness and safety of empagliflozin-based quadruple therapy compared with insulin glargine-based therapy in patients with inadequately controlled type 2 diabetes: An observational study in clinical practice.

This open-label, prospective study evaluated the effectiveness and safety of empagliflozin as add-on therapy in inadequately controlled type 2 diabetes (T2D) patients (glycated haemoglobin [HbA1c], 7.5-12%) who were already using three other types of orally active antidiabetic agents. A total of 268 T2D patients were enrolled and divided into two groups, empagliflozin (EMPA 25 mg/d, n = 142) or insulin glargine (INS, n = 126), respectively. After the treatment period of 24 weeks, HbA1c and fasting plasma glucose (FPG) were significantly reduced (HbA1c, P = 0.004; FPG, P = 0.008, respectively) in the EMPA group compared to the INS group. Also, EMPA treatment evoked a significant reduction in body weight (P < 0.001) and systolic blood pressure (P = 0.017) compared to the INS group. Hypoglycaemic adverse events were significantly higher in the INS group compared to the EMPA group (P = 0.001). In conclusion, this study demonstrated that a regimen comprising four different orally active antidiabetic agents, including EMPA, was effective and safe as a therapeutic strategy for treating T2D patients for glycaemic control and improvement of other cardiovascular and metabolic indices.

Associations between the HaeIII Single Nucleotide Polymorphism in the SLC2A1 Gene and Diabetic Nephropathy in Korean Patients with Type 2 Diabetes Mellitus.

BACKGROUND: Diabetic nephropathy (DN) is the most serious microvascular complication of diabetes mellitus and is one of the leading causes of end stage renal failure. In previous studies, the contribution of genetic susceptibility to DN showed inconsistent results. In this study, we investigated the association between the solute carrier family 2 facilitated glucose transporter member 1 (SLC2A1) HaeIII polymorphism and DN in Korean patients with type 2 diabetes mellitus (T2DM) according to disease duration. METHODS: A total of 846 patients with T2DM (mean age, 61.3 ± 12.3 years; mean duration of T2DM, 10.3 ± 7.9 years; 55.3% men) who visited the Chungbuk National University Hospital were investigated. The HaeIII polymorphism of the SLC2A1 gene was determined by the real time polymerase chain reaction method. Genotyping results were presented as GG, AG, or AA. A subgroup analysis was performed according to duration of T2DM (≤ 10 years, > 10 years). RESULTS: The AG + AA genotype showed a significantly higher risk of DN compared with the GG genotype in patients with a type 2 DM duration less than 10 years (12.4% vs. 4.2%; P < 0.001). No significant differences were observed in terms of other diabetic complications, including retinopathy, peripheral neuropathy, cardiovascular disease, cerebrovascular disease or peripheral artery disease, according to the genotypes of the SLC2A1 HaeIII polymorphism. CONCLUSION: The SLC2A1 HaeIII polymorphism was associated with DN in Korean patients with T2DM, particularly in the group with a relatively short disease duration.

Association of Adiponectin 45T/G Polymorphism with Diabetic Cardiovascular Complications in Korean Type 2 Diabetes.

BACKGROUND: Adiponectin is an adipokine that regulates lipid and glucose metabolism and has been shown to have anti-inflammatory and anti-atherogenic effects. It also plays an important role in the development of cardiovascular disease (CVD). METHODS: This study evaluated the association between adiponectin 45T/G polymorphism and cardiovascular complication in type 2 diabetes in Koreans. RESULTS: The present study included 758 patients with type 2 diabetes. The distribution of the adiponectin 45T/G polymorphism was 3.56% (n = 27) for GG, 42.35% (n = 321) for TG, and 54.09% (n = 410) for TT in patients with type 2 diabetes. The prevalence of CVD was significantly higher in subjects with the GG + TG genotype compared to those with the TT genotype (17.5% vs. 9.8%, P = 0.002). The G allele was associated with a higher risk of CVD (P = 0.002). CONCLUSION: Our findings suggest that the adiponectin 45T/G polymorphism is associated with diabetic cardiovascular complication in type 2 diabetes.

Prevalence of Malnutrition in Hospitalized Patients: a Multicenter Cross-sectional Study.

BACKGROUND: Malnutrition is associated with many adverse clinical outcomes. The present study aimed to identify the prevalence of malnutrition in hospitalized patients in Korea, evaluate the association between malnutrition and clinical outcomes, and ascertain the risk factors of malnutrition. METHODS: A multicenter cross-sectional study was performed with 300 patients recruited from among the patients admitted in 25 hospitals on January 6, 2014. Nutritional status was assessed by using the Subjective Global Assessment (SGA). Demographic characteristics and underlying diseases were compared according to nutritional status. Logistic regression analysis was performed to identify the risk factors of malnutrition. Clinical outcomes such as rate of admission in intensive care units, length of hospital stay, and survival rate were evaluated. RESULTS: The prevalence of malnutrition in the hospitalized patients was 22.0%. Old age (≥ 70 years), admission for medical treatment or diagnostic work-up, and underlying pulmonary or oncological disease were associated with malnutrition. Old age and admission for medical treatment or diagnostic work-up were identified to be risk factors of malnutrition in the multivariate analysis. Patients with malnutrition had longer hospital stay (SGA A = 7.63 ± 6.03 days, B = 9.02 ± 9.96 days, and C = 12.18 ± 7.24 days, P = 0.018) and lower 90-day survival rate (SGA A = 97.9%, B = 90.7%, and C = 58.3%, P < 0.001). CONCLUSION: Malnutrition was common in hospitalized patients, and resulted in longer hospitalization and associated lower survival rate. The rate of malnutrition tended to be higher when the patient was older than 70 years old or hospitalized for medical treatment or diagnostic work-up compared to elective surgery.

The Efficacy and Safety of Sodium-Glucose Co-transporter 2 (SGLT2) Inhibitors in Real-World Clinical Practice: Potential Cautionary Use in Elderly Patients with Type 2 Diabetes (T2D).

INTRODUCTION: Sodium-glucose co-transporter 2 (SGLT2) inhibitors have shown safe and therapeutic efficacy in randomized controlled trials (RCT) to reduce adverse cardiorenal events in high-risk patients with type 2 diabetes (T2D). In this study, we investigated the efficacy and safety of SGLT2 intervention in patients with T2D in a real-world clinical practice to confirm the validity of the RCT results. METHODS: As a retrospective study, we evaluated medical records from 596 patients with T2D treated with SGLT2 inhibitors (dapagliflozin or empagliflozin) in addition to their prior drug regimen to improve glucose control between 2015 and 2019 in the Endocrinology Department at Chungbuk National University Hospital. No control arm was evaluated to compare the effects of adding SGLT inhibitors to the pre-existing regimen. The primary objective was the measurement of glycated hemoglobin (HbA1c) from each individual patient over a 36-month period at 6-month intervals. The secondary parameters were the measurement of fasting plasma glucose (FPG) and body weight (Bwt) changes, as well as the monitoring of adverse events (AEs) and determining the reasons for drug discontinuation. RESULTS: HbA1c levels were reduced at each of the time points throughout the 36-month period and were significantly reduced by 12.5% (P < 0.01) from time 0 (8.8 ± 1.3%) to 36 months (7.7 ± 1.0%). FPG levels [from basal (180 ± 60 mg/dL) to 36 months (138 ± 38 mg/dL)] and Bwt [from basal (74 ± 15 kg) to 36 months (72 ± 15 kg)] were also significantly reduced (P < 0.01) for both measurements in the SGLT2 inhibitor add-on group. Similar to HbA1c profile, the FPG and Bwt were measured at a consistently lower level at 6 months until the end of the study. The most common AEs were hypoglycemia (n = 57), genitourinary infection (GUI) (n = 31), and polyuria (n = 28). In the elderly population (≥ 75 years old), AEs (31%) were generally more prevalent (P < 0.001) than those (21%) in the adult (< 75 years old) patients. Over the study period, 211 (35%) patients either dropped or completely discontinued the use of the SGLT2 inhibitor, and the elderly patients tended to have a higher discontinuation rate (52%; P = 0.005) than the adults (33%). CONCLUSIONS: In this study, we demonstrated that SGLT2 inhibitors are an effective and durable hypoglycemic agent to control blood glucose levels with reduced maintenance of Bwt, but their use in the elderly (≥ 75 years old) patients with T2D may warrant some additional caution due to increased probability of AEs and discontinuation of drug use.

Development of AI-generated medical responses using the ChatGPT for cancer patients.

BACKGROUND AND OBJECTIVE: To develop a healthcare chatbot service (AI-guided bot) that conducts real-time conversations using large language models to provide accurate health information to patients. METHODS: To provide accurate and specialized medical responses, we integrated several cancer practice guidelines. The size of the integrated meta-dataset was 1.17 million tokens. The integrated and classified metadata were extracted, transformed into text, segmented to specific character lengths, and vectorized using the embedding model. The AI-guide bot was implemented using Python 3.9. To enhance the scalability and incorporate the integrated dataset, we combined the AI-guide bot with OpenAI and the LangChain framework. To generate user-friendly conversations, a language model was developed based on Chat-Generative Pretrained Transformer (ChatGPT), an interactive conversational chatbot powered by GPT-3.5. The AI-guide bot was implemented using ChatGPT3.5 from Sep. 2023 to Jan. 2024. RESULTS: The AI-guide bot allowed users to select their desired cancer type and language for conversational interactions. The AI-guided bot was designed to expand its capabilities to encompass multiple major cancer types. The performance of the AI-guide bot responses was 90.98 ± 4.02 (obtained by summing up the Likert scores). CONCLUSIONS: The AI-guide bot can provide medical information quickly and accurately to patients with cancer who are concerned about their health.

Efficacy and Safety of Metformin and Atorvastatin Combination Therapy vs. Monotherapy with Either Drug in Type 2 Diabetes Mellitus and Dyslipidemia Patients (ATOMIC): Double-Blinded Randomized Controlled Trial.

Background: It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia. Methods: This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment. Results: After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. -0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (-55.20% vs. -7.69%, P<0.001) without previously unknown adverse drug events. Conclusion: The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin's preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.

Isolation of a thermophilic bacterium capable of low-molecular-weight polyethylene degradation.

A thermophilic bacterium capable of low-molecular-weight polyethylene (LMWPE) degradation was isolated from a compost sample, and was identified as Chelatococcus sp. E1, through sequencing of the 16S rRNA gene. LMWPE was prepared by thermal degradation of commercial PE in a strict nitrogen atmosphere. LMWPE with a weight-average-molecular-weight (Mw) in the range of 1,700-23,700 was noticeably mineralized into CO(2) by the bacterium. The biodegradability of LMWPE decreased as the Mw increased. The low molecular weight fraction of LMWPE decreased significantly as a result of the degradation process, and thereby both the number-average-molecular-weight and Mw increased after biodegradation. The polydispersity of LMWPE was either narrowed or widened, depending on the initial Mw of LMWPE, due to the preferential elimination of the low molecular weight fraction, in comparison to the high molecular weight portion. LMWPE free from an extremely low molecular weight fraction was also mineralized by the strain at a remarkable rate, and FTIR peaks assignable to C-O stretching appeared as a result of microbial action. The FTIR peaks corresponding to alkenes also became more intense, indicating that dehydrogenations occurred concomitantly with microbial induced oxidation.

Prospective observation of 5-year clinical course of subclinical hypothyroidism in korean population.

Subclinical hypothyroidism (SCH) is a common clinical condition, whereas it's natural course has not been identified distinctly. We evaluated the natural history of 169 SCH patients over 5-yr and the prognostic factors including thyroid autoantibodies and thyroid ultrasonographic (USG) findings related to develop overt hypothyroidism. After 5 yr, 47.3% of patients showed normalization of TSH, while 36.7% of patients remained persistence of high level of TSH, and overt hypothyroidism developed in 11.2% of patients. There were painless thyroiditis (2.9%) and hyperthyroidism (1.7%) during 5 yr follow-up. The thyroid nodule was seen in 48.6% of patients. Most of patients had 1 to 2 nodules whereas only 3% of patients with thyroid nodule had more than 6 nodules. Overt hypothyroidism patients had more heterogenous echogenecity in USG compared to patients with normalization or persistent SCH (76.5% vs 50.0% vs 35.0%, P = 0.048) and higher prevalence positive anti-thyroid peroxidase (anti-TPO Ab) and anti-thyroglobulin antibody (anti-Tg Ab) and titer of anti-TPO Ab than other two groups. The cut off values for prediction of overt hypothyroidism were TSH > 7.45 µIU/mL, free T4 < 1.09 ng/dL and Anti-TPO Ab > 560 IU/mL. SCH has various courses and initial TSH, free T4, presence of thyroid autoantibody, titer of thyroid autoantibody; and thyroid USG findings can serve as a prognostic factor for progression of overt hypothyroidism. These parameters suggest consideration to initiate thyroid hormone treatment in SCH.

Survival Benefit after Shifting from Upfront Surgery to Neoadjuvant Treatment in Borderline Resectable Pancreatic Cancer.

According to the 2016 National Comprehensive Cancer Network (NCCN) guidelines, patients with borderline resectable pancreatic cancer (BRPC) should receive chemotherapy as the first-line treatment. This study examined the real-world survival benefits of modifying BRPC treatment guidelines. Patients treated for BRPC at a single institution from 2013 to 2015 (pre-guideline group) and 2017 to 2019 (post-guideline group) were retrospectively reviewed. According to the treatment method used, patients were classified into upfront surgery (US), surgery after neoadjuvant treatment (NAT), and chemotherapy only (CO) groups. Overall survival (OS) was compared according to period and treatment type. Factors associated with OS were analyzed using a Cox regression model. Among the 165 patients, 63 were in the pre-guideline group and 102 patients were in the post-guideline group. The median OS was significantly improved in the post-guideline group compared to the pre-guideline group (29 vs. 13 months, p < 0.001). According to the treatment method, the median OS of the NAT group was significantly longer than that of the US and CO groups (40 vs. 16 vs. 15 months, respectively, p < 0.001). In multivariate analysis, tumor size, differentiation, NAT, and perineural invasion were significant prognostic factors. NAT is an important treatment option for BRPC and increased patient survival in the real world.

Prognosis of pancreaticoduodenectomy in octogenarians for pancreatic ductal adenocarcinoma with propensity score matched analysis.

BACKGROUND: This retrospective study investigates factors affecting surgical and oncological outcome after performing pancreaticoduodenectomy in octogenarian patients diagnosed with pancreatic ductal adenocarcinoma. METHODS: From January 2009 to December 2018, patients who underwent pancreaticoduodenectomy for pancreatic ductal adenocarcinoma were included. Data were analysed by comparing clinicopathological characteristics, complications, survival, recurrence, adjuvant treatment between octogenarians and the younger group. Propensity score matched analysis was performed due to the small size of the octogenarian group. RESULTS: A total of 666 patients were included in this study and 24 (3.6%) were included in the octogenarian group. Short term complication rates (P = 0.119) and hospital stay (P = 0.839) did not differ between two groups. Overall survival between the two groups showed significant difference (<80 median 25 months versus ≥80 median 13 months, P = 0.045). However, after propensity score matched analysis, the two groups did not differ in overall survival (<80 median 18 months versus ≥80 median survival 16 months, P = 0.565) or disease-free survival (P = 0.471). Among the octogenarians, six patients survived longer than 24 months even without satisfying all favourable prognostic factors. CONCLUSION: Considering the general condition of octogenarians diagnosed with pancreatic ductal adenocarcinoma, select patients should be treated more aggressively for the best chance of receiving curative treatment.

Nationwide Trends in Osteoporosis in Koreans With Disabilities From 2008 to 2017.

This study examined the 10-year trends in the prevalence of osteoporosis according to disability grade and type compared with those without disabilities in South Korea. We linked national disability registration data with the National Health Insurance claims data. Age- and sex-standardized prevalence of osteoporosis were analyzed from 2008 to 2017 according to sex, disability type, and disability grade. Adjusted odds ratios for osteoporosis according to disability characteristics in the most recent years' data were also confirmed by multivariate analysis. Over the past decade, the prevalence of osteoporosis has increased in people with disabilities compared with people without disabilities, and the gap has gradually widened from 7% to 15%. By analysis of the most recent year data, both male and female individuals with disabilities had a higher risk of osteoporosis than those without disability (odds ratios [OR] 1.72, 95% confidence interval [CI] 1.70-1.73 in males; OR 1.28, 95% CI 1.27-1.28 in females); the multivariate-adjusted OR was especially prominent in disability related to respiratory disease (OR 2.07, 95% CI 1.93-2.21 in males; OR 1.74; 95% CI 1.60-1.90 in females), epilepsy (OR 2.16, 95% CI 1.78-2.61 in males; OR 1.71; 95% CI 1.53-1.91 in females), and physical disability types (OR 2.09, 95% CI 2.06-2.21 in males; OR 1.70; 95% CI 1.69-1.71 in females). In conclusion, the prevalence and risk of osteoporosis have increased in people with disabilities in Korea. In particular, the risk of osteoporosis increases significantly in people with respiratory diseases, epilepsy, and physical disability types. © 2023 The Authors.

Different Oncologic Outcomes According to Margin Status (High-Grade Dysplasia vs. Carcinoma) in Patients Who Underwent Hilar Resection for Mid-Bile Duct Cancer.

Margin positivity after hilar resection (HR) for bile duct cancer is commonly observed due to its longitudinal spread along the subepithelial plane; nevertheless, we cannot draw conclusions regarding the prognostic effects of margins with high-grade dysplasia (HGD) or carcinoma. We aimed to investigate the oncologic effect according to the margin status after HR, particularly between the R1 HGD and the R1 carcinoma. From 2008 to 2017, 149 patients diagnosed with mid-bile duct cancer in Samsung Medical Center, South Korea, were divided according to margin status after HR and retrospectively analyzed. Recurrence patterns were also analyzed between the groups. There were 126 patients with R0 margins, nine with R1 HGD, and 14 with R1 carcinoma. The mean age of the patients was 68.3 (±8.1); most patients were male. The mean age was higher in R1 carcinoma patients than in R1 HGD and R0 patients (p = 0.014). The R1 HGD and R1 carcinoma groups had more patients with a higher T-stage than R0 (p = 0.079). In univariate analysis, the prognostic factors affecting overall survival were age, T- and N-stage, CA19-9, and margin status. The survival rate of R0 was comparable to that of R1 HGD, but the survival rate of R0 was significantly better compared to R1 carcinoma (R0 vs. R1 HGD, p = 0.215, R0 vs. R1 carcinoma, p = 0.042, respectively). The recurrence pattern between the margin groups did not differ significantly (p = 0.604). Extended surgery should be considered for R1 carcinoma; however, in R1 HGD, extended operation may not be necessary, as it may achieve oncologic outcomes similar to R0 margins with HR.

Influenza vaccination trend and related factors among patients with diabetes in Korea: Analysis using a nationwide database.

Background: Subjects with diabetes are at higher risk of serious influenza-related complications. We aimed to investigate the yearly trend of influenza vaccination and factors associated with being unvaccinated for influenza in subjects with diabetes using a nationwide observational study performed within the recent decade. Methods: Among 105,732 subjects from the Korea National Health and Nutrition Examination Survey between 2007 and 2019, 8,632 with diabetes were included. We investigated the yearly trend of influenza vaccination and factors associated with being unvaccinated for influenza. Results: During the study period, the prevalence of influenza vaccination in subjects with diabetes showed a tendency to increase every year, reaching almost 60% in 2019, which was higher than the rate in subjects without diabetes. Younger age (adjusted hazard ratio (aHR) [95% CI] 11.29 [8.63-14.75] for < 50 years; 6.16 [5.21-7.29] for 50-65 years), male (aHR 1.67 [1.52-1.87]), current smoker (aHR 1.31 [1.00-1.72], lower-income status (aHR 1.46 [1.17, 1.84]), and high education level (aHR 1.30 [1.01-1.67]) were associated with being unvaccinated. Also, a poorer glycemic control with HbA1c ≥ 9% was found to be correlated with unvaccinated status (aHR 1.48 [1.15-1.90]). Conclusion: The influenza vaccination rate is still unsatisfactory in subjects with diabetes. Young age, males, low-income level, high education level, and poor glycemic control were associated with unvaccinated status. Considering the risk-benefits of influenza vaccination in patients with diabetes, physicians should make an effort to increase vaccination rates, especially in low vaccination rate groups.

Utilization of end to side inverted mattress pancreaticojejunostomy for Duval procedure: A case report.

Although a pancreaticojejunostomy (PJ) is not required after a distal pancreatectomy in most cases, it needs to be performed to prevent atrophy of the remnant pancreas when the proximal duct is obstructed by a tumor, stone, or etc. In these conditions, the critical postoperative pancreatic fistula (POPF) gives surgeons cause to hesitate before performing a PJ. We previously presented the modified technique of Mattress PJ named "inverted mattress PJ" (IM-PJ) and published improved outcomes in the aspects of POPF after a pancreaticoduodenectomy and a central pancreatectomy. Recently, we had a case of a patient who has chronic pancreatitis with a proximal pancreatic duct obstruction, requiring a distal pancreatectomy and PJ. Based on the previous report, we decided to apply the "inverted mattress PJ" (IM-PJ) technique for a Roux-en Y PJ after a distal pancreatectomy. The patient was discharged after surgery without complications. We reviewed a case of a patient requiring PJ following a distal pancreatectomy and discussed the safety of our technique.
