ABSTRACT
Background@#This study aimed to investigate real-world data of C-terminal telopeptide (CTX), propeptide of type I collagen (P1NP), and osteocalcin through present multicenter clinical study, and retrospectively analyze the usefulness of bone turnover markers (BTMs) in Koreans. @*Methods@#The study focused on pre- and post-menopausal patients diagnosed with osteoporosis and excluded patients without certain test results or with test intervals of over 1 year. The demographic data and 3 BTMs (CTX, P1NP, and osteocalcin) were collected. The patients were classified by demographic characteristics and the BTM concentrations were analyzed by the group. @*Results@#Among women with no history of fractures, the levels of P1NP (N=2,100) were 43.544±36.902, CTX (N=1,855) were 0.373 ±0.927, and osteocalcin (N=219) were 10.81 ±20.631. Among men with no history of fractures, the levels of P1NP (N=221) were 48.498±52.892, CTX (N=201) were 0.370±0.351, and osteocalcin (N=15) were 7.868 ±10.674. Treatment with teriparatide increased the P1NP levels after 3 months in both men and women, with a 50% increase observed in women. Similarly, treatment with denosumab decreased the CTX levels after 3 months in both men and women, with a reduction of 50% observed in women. @*Conclusions@#The results of this study can contribute to the accurate assessment of bone replacement status in Koreans. We also provide the P1NP level in the Korean population for future comparative studies with other populations.
ABSTRACT
Background@#Several studies have reported associations between obesity and autonomic dysfunction. However, little research has investigated the effect of bariatric surgery on heart rate recovery (HRR) in the treadmill test and heart rate variability (HRV) in 24-hour Holter monitoring. We investigated the effects of bariatric surgery on HRR and HRV, which are parameters related to autonomic dysfunction. @*Methods@#We retrospectively investigated patients who underwent bariatric surgery in 2019. The treadmill test, 24-hour Holter monitoring, and echocardiography were performed before and 6 months after surgery. We compared the changes in HRR in the treadmill test and HRV parameters such as the time domain and spectral domain in 24-hour Holter monitoring before and after surgery. @*Results@#Of the 40 patients who underwent bariatric surgery, 25 patients had the treadmill test or 24-hour Holter monitoring both before and after surgery. Body weight and body mass index significantly decreased after surgery (112.86±24.37 kg vs. 89.10±20.26 kg, p<0.001; 39.22±5.69 kg/m2 vs. 31.00±5.09 kg/m2, p<0.001, respectively). HRR significantly increased (n=23; 43.00±20.97 vs. 64.29±18.49, p=0.001). The time domain of HRV parameters increased (n=21; standard deviation of the N-N interval 123.57±28.05 vs. 152.57±39.49, p=0.002 and mean N-N interval 791.57±88.84 vs. 869.05±126.31, p=0.002). @*Conclusions@#Our data showed that HRR after exercise and HRV during 24-hour Holter monitoring improved after weight reduction with bariatric surgery through improved cardiac autonomic function.
ABSTRACT
Background@#Current evidence support that the gut microbiota plays a potential role in obesity. Bariatric surgery can reduce excess weight and decrease the risk of life-threatening weight-related health problems and may also influence gut microbiota. In this study, we aimed to investigate the changes in gut microbiota before and after bariatric surgery and evaluate the association of the gut microbial shift and altered body mass index (BMI) after bariatric surgery. @*Methods@#Between January 2019 and July 2020, stools from 58 patients scheduled for bariatric surgery were collected. Six months after bariatric surgery, stools from 22 of these patients were re-collected, and the changes in gut microbiota before and after bariatric surgery were evaluated. In addition, the differences in gut microbiota between patients with severe obesity (BMI >35 kg/m2, n=42) and healthy volunteers with normal BMI (18.8 to 22.8 kg/m2, n=41) were investigated. @*Results@#The gut microbiota of patients who underwent bariatric surgery showed increased α-diversity and differed β-diversity compared with those before surgery. Interestingly, Blautia was decreased and Bacteriodes was increased at the genus level after bariatric surgery. Further, the Blautia/Bacteroides ratio showed a positive correlation with BMI. To validate these results, we compared the gut microbiota from severely obese patients with high BMI with those from healthy volunteers and demonstrated that the Blautia/Bacteroides ratio correlated positively with BMI. @*Conclusion@#In the gut microbial analysis of patients who underwent bariatric surgery, we presented that the Blautia/Bacteroides ratio had changed after bariatric surgery and showed a positive correlation with BMI.
ABSTRACT
Thyroid hormones have an important physiological role in maintaining adult bone structure and strength. Therefore, thyroid dysfunction is inevitably associated with various degrees of skeletal consequences. Endogenous overt hyperthyroidism is an established cause of high bone turnover with accelerated bone loss, resulting in osteoporosis and an increased risk of fractures. Hyperthyroidism induced by thyroid stimulating hormone suppression therapy in patients with differentiated thyroid cancer also has emerged as a contributing factor to osteoporosis and fragility fractures. While, there is lack of evidence that hypothyroidism negatively affects bone health. Although there is growing clinical evidence of the importance of bone health in hyperthyroidism, clinical guidelines on how to evaluate and manage bone health in these diseases have not yet been published worldwide. The Task Force from the Korean Thyroid Association Committee of Clinical Practice Guideline has developed this position statement for the evaluation and management of bone health in patients with thyroid diseases, particularly focused on endogenous hyperthyroidism and thyroid stimulating hormone suppression therapyassociated hyperthyroidism in patients with differentiated thyroid cancer.
ABSTRACT
Objectives@#It is well known that type 2 diabetes (T2DM) is dramatically improved after bariatric surgery, although the mechanisms have not been clearly identified. The skill required for gastric surgery for gastric cancer is very similar to that needed in bariatric surgery. In this study, we evaluated the immediate improvement of T2DM after gastrectomy for gastric cancer. @*Methods@#A total of nine patients who were diagnosed with early gastric cancer (EGC) and already had T2DM underwent a 75 g oral glucose tolerance test (OGTT) before surgery and within two weeks after gastrectomy. Glucose, insulin, and c-peptide were measured before, and 30 and 60 minutes after ingesting 75 g of glucose. From these trials, we calculated the HOMA-IR, insulinogenic index, Matsuda index, and area under the curve (AUC). @*Results@#The mean age of participants was 57.23 ± 11.08 years and eight of them were men. HOMA-IR (4.2 vs. 2.3, P = 0.012) levels were decreased after surgery. There were no significant differences of insulinogenic index, fasting blood sugar before and after surgery. The Matsuda index (3.3 vs. 8.3, P = 0.002) was significantly increased and AUC (512.9 vs. 388.7 mg-hr/dL, P > 0.001) upon 75 g OGTT was significantly decreased after surgery. @*Conclusions@#Insulin sensitivity was immediately improved after gastrectomy for early gastric cancer in patients with T2DM.
ABSTRACT
Background@#We aimed to evaluate the clinicopathological features and biological behaviors of Korean thyroid cancer patients with rare variants of papillary thyroid carcinoma (PTC) to address the ambiguity regarding the prognostic consequences of these variants. @*Methods@#We retrospectively reviewed the medical records of 5,496 patients who underwent thyroid surgery for PTC, between January and December 2012, in nine tertiary hospitals. Rare PTC variants included tall cell (TCV), columnar cell (CCV), diffuse sclerosing (DSV), cribriform-morular (CMV), solid (SV), hobnail, and Warthin-like variants. Recurrence-free survival (RFS) was defined as the time from the date of thyroidectomy until recurrence. @*Results@#Rare variants accounted for 1.1% (n=63) of the PTC patients; with 0.9% TCV, 0.02% CCV, 0.1% DSV, 0.1% CMV, and 0.1% SV. The mean age of patients and primary tumor size were 42.1±13.1 years and 1.3±0.9 cm, respectively. Extrathyroidal extension and cervical lymph node metastasis were observed in 38 (60.3%) and 37 (58.7%) patients, respectively. Ultrasonographic findings revealed typical malignant features in most cases. During a median follow-up of 7 years, 6.3% of patients experienced a locoregional recurrence. The 5-year RFS rates were 71.4% in patients with DSV or SV, 95.9% for TCV, or CCV, and 100% for other variants. DSV emerged an independent risk factor associated with shorter RFS. @*Conclusion@#In this multicenter Korean cohort, rare variants accounted for 1.1% of all PTC cases, with TCV being the most frequent subtype. DSV emerged as a significant prognostic factor for RFS.

ABSTRACT
Growth hormone (GH) deficiency is caused by congenital or acquired causes and occurs in childhood or adulthood. GH replacement therapy brings benefits to body composition, exercise capacity, skeletal health, cardiovascular outcomes, and quality of life. Before initiating GH replacement, GH deficiency should be confirmed through proper stimulation tests, and in cases with proven genetic causes or structural lesions, repeated GH stimulation testing is not necessary. The dosing regimen of GH replacement therapy should be individualized, with the goal of minimizing side effects and maximizing clinical improvements. The Korean Endocrine Society and the Korean Society of Pediatric Endocrinology have developed a position statement on the diagnosis and treatment of GH deficiency. This position statement is based on a systematic review of evidence and expert opinions.
ABSTRACT
Purpose@#High rate of false-positive tests is a major obstacle to use human papillomavirus (HPV) detectionas a diagnostic tool for high-grade squamous intraepithelial lesions or cervical cancer(HSIL+). We investigated whether type-specific viral load or physical state of HPV 16, 18,and 58 are useful biomarkers for HSIL+. @*Materials and Methods@#Type-specific viral loads of E6 and E2 genes in cervical cells from 240, 83, and 79 HPV 16–,18–, and 58–infected women, respectively, were determined using real-time polymerasechain reaction. Viral loads were normalized to cellular DNA (copy/cell). Total and integratedviral loads and physical state were compared between HSIL+ and controls, and diagnosticvalue was determined using receiver operating characteristic analysis. @*Results@#Viral loads of HPV 16, 18, and 58 were significantly different in lesions in the same pathologicgrade. High type-specific total viral loads were significantly associated with HSIL+ (oddsratio [OR], 14.065, 39.472, and 7.103 for HPV 16, 18, and 58, respectively). High integratedviral load was related to HSIL+ in women with HPV 16 (OR, 8.242), and integrated statewas associated with HSIL+ in women with HPV 18 (OR, 9.443). Type-specific total viral loadwas significantly associated with HSIL+ (area under curve, 0.914, 0.937, and 0.971 forHPV 16, 18, and 58, respectively), indicating an excellent performance in detecting HSIL+. @*Conclusion@#Type-specific total viral load may be a powerful diagnostic marker for HSIL+ in HPV 16–,18–, and 58–infected HSIL+ lesions. If demonstrated in all other high-risk HPV types, thismethod can lead to a paradigm shift in the strategy of equivocal cytologic abnormalities.
ABSTRACT
Purpose@#The purpose of this study was to identify the effects of self-differentiation, psychological discomfort, and dyadic adjustment on maternal-fetal attachment in primigravidae. @*Methods@#In total, 108 primigravidae participated in this correlational study. The participants answered self-report questionnaires. Data were collected from January 14, 2020 to May 4, 2020, and were analyzed using descriptive statistics, the t-test, analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression with SPSS for Windows ver. 23.0. @*Results@#The mean age of the primigravidae was 31.66 years. The mean score for the degree of maternal-fetal attachment was 76.81 out of 96 points. Participants’ scores for maternal-fetal attachment differed significantly based on age (t=2.08 p=.039) and marital status (t=2.05, p=.043). Maternal-fetal attachment was significantly negatively correlated with psychological discomfort (r=–.39, p<.001), and significantly positively correlated with self-differentiation (r=.36, p<.001) and dyadic adjustment (r=.36, p<.001). Self-differentiation explained 24.1% of variance in participants’ maternal-fetal attachment, and its effect was statistically significant (F=7.79, p<.001). @*Conclusion@#In primigravidae, more self-differentiation was associated with stronger maternal-fetal attachment. To strengthen maternal-fetal attachment in primigravidae, it is necessary to develop an educational program that increases their level of self-differentiation and minimizes their psychological discomfort. Additionally, it is recommended to provide nursing interventions to encourage couples to work together throughout the gestational period.

ABSTRACT
OBJECTIVES: Iodine deficiency causes multiple health problems. Previously we reported that 96% of high school students in Tuguegarao, Philippines had adequate iodine levels. However, iodine deficiency-associated problems remain among adults in the Philippines. Therefore, we evaluated iodine nutritional status and goiter prevalence among adults, including pregnant women, in Tuguegarao, Philippines. METHODS: A total of 245 adults, including 31 pregnant women, provided samples for urinary iodine analysis, and all pregnant women completed a questionnaire about iodine deficiency. RESULTS: The median urinary iodine level was 164.0 ± 138.4 µg/L; 38.4% of the participants were iodine deficient, according to the International Council for Control of Iodine Deficiency Disorders (ICCIDD) criteria. No severe iodine deficiency was observed. Among the 31 pregnant women, 24 (77.5%) fell into the iodine deficient category defined by a stricter World Health Organization (WHO) guideline, in which iodine deficiency is considered when urinary iodine levels are below 150 µg/L. Almost half (42%) of the pregnant women were unaware of the harmful effects of iodine deficiency on the human body and their fetus. CONCLUSIONS: Although iodine nutritional status in the Philippines has improved, iodine deficiency still exists among adults, especially among pregnant women. Therefore, our study strongly suggests that a better strategy should be established to monitor iodine nutritional status among adults continually, and to focus on populations susceptible to iodine deficiency, including pregnant women and women of reproductive age, to achieve the total elimination of iodine deficiency.

BACKGROUND: Korea is considered an iodine sufficient country, and several studies have been conducted regarding iodine status in healthy Korean adults, pregnant women, and preschool children. However, data on iodine status in Korean school-age children are lacking. Therefore, the iodine nutrition status of Korean school-age children was investigated by measuring urine iodine concentration (UIC). METHODS: This cross-sectional study conducted between April and September 2016 comprised 373 school-age children. UIC was determined using a modified microplate method employing ammonium persulfate digestion followed by Sandell-Kolthoff reaction. RESULTS: The median UIC was 458.2 µg/L. Excessive iodine intake (>300 µg/L) was found in 286 children (76.7%), with extremely high values exceeding 1,000 µg/L in 19.6% of subjects. Insufficient iodine intake (<100 µg/L) was observed in eight children (2.1%). UIC values were not significantly different between sexes. CONCLUSION: Korean school-age children showed excessive iodine intake. Therefore, education regarding adequate iodine intake in school-age children is needed.

The concept of bariatric surgery, which was intended to lose weight, has turned into metabolic surgery. These changes were due to the fact that the resolution of diabetes and metabolic diseases after weight loss surgery were not associated with weight loss. The key pathogenesis of type 2 diabetes is explained by increased insulin resistance and reduced insulin secretion. Therefore, postoperative resolution of diabetes can be explained by improvement of insulin secretion or insulin resistance. It is known that the improvement of insulin secretion after surgery depends on the degree of preservation of preoperative beta cell function. In this study, the method of measuring insulin resistance is concretely summarized, and the improvement of diabetes after metabolic obesity surgery is focused on the improvement of insulin resistance.

OBJECTIVES: With the rapid increase in the prevalence of diabetes, the age groups of diabetic patients are becoming diversified. This study will examine the degree of obesity, insulin resistance, and insulin secretion ability among patients first diagnosed with diabetes according to age and gender. METHODS: The subjects of this study included 616 patients who were first diagnosed with diabetes during a routine physical examination. This sample was obtained from a total of 28,075 adults aged 19 years and older who received the examination among 33,829 participants in the Korea National Health & Nutrition Examination Survey (KNHANES) from 2007–2010. The subjects were categorized by age into young age (age: 19 – 39 years), middle age (age: 40 – 59 years), and old age (age: 60 years and older). The degree of obesity was categorized according to body mass index (BMI) into normal weight (BMI: 18.5 ~ 22.9), overweight (BMI: 23 ~ 24.9), and obesity (BMI: 25 or above). Insulin resistance was evaluated by homeostatic model assessment of insulin resistance (HOMA-IR). RESULTS: It was found that 14.1% (n = 87) of a total of 616 subjects (324 men, 292 women) were in the young age group, 43.8% (n = 270) were in the middle age group, and 42.1% (n = 259) were in the old age group. In addition, 83.3% of men that were overweight or obesity were in the young age group, while 79.2% and 60.5% were in the middle age and old age groups, respectively. A total of 82.2% of women that were overweight or obesity were in the young age group, while 79.5% and 77% were in the middle age and old age groups, respectively. For men, the more obesity they were in all age groups, the higher their HOMA-IR. For women, the more obesity they were in the young age and middle age groups, the higher their HOMA-IR; however, women in the old age group showed the highest HOMA-IR when they were of normal weight. CONCLUSION: Among diabetic patients first diagnosed with the disease in Korea, the youth population had the highest obesity rate. Insulin resistance increases as an individual's weight increases among those patients who are first diagnosed with diabetes; the only exception noted is for elderly women.

BACKGROUND: The aim of this study was to investigate the prevalence of obesity in Korean men with Klinefelter syndrome (KS) and the associated risk factors for obesity and hyperglycemia. METHODS: Data were collected retrospectively from medical records from 11 university hospitals in Korea between 1994 and 2014. Subjects aged ≥18 years with newly diagnosed KS were enrolled. The following parameters were recorded at baseline before treatment: chief complaint, height, weight, fasting glucose level, lipid panel, blood pressure, testosterone, luteinizing hormone, follicle-stimulating hormone, karyotyping patterns, and history of hypertension, diabetes, and dyslipidemia. RESULTS: Data were analyzed from 376 of 544 initially enrolled patients. The rate of the 47 XXY chromosomal pattern was 94.1%. The prevalence of obesity (body mass index ≥25 kg/m²) in Korean men with KS was 42.6%. The testosterone level was an independent risk factor for obesity and hyperglycemia. CONCLUSION: Obesity is common in Korean men with KS. Hypogonadism in patients with KS was associated with obesity and hyperglycemia.

BACKGROUND: We evaluated the associations between 25-hydroxyvitamin D (25(OH)D) concentrations in serum and insulin resistance in the healthy Korean population. METHODS: We conducted this cross-sectional analysis in 1,807 healthy Korean people (628 men and 1,179 women) aged 30 to 64 years in the Cardiovascular and Metabolic Disease Etiologic Research Center study. All participants were assessed for 25(OH)D, fasting glucose, and insulin levels, and completed a health examination and lifestyle questionnaire according to standard procedures. Insulin resistance was defined as the homeostasis model assessment insulin resistance higher than the 75 percentile. RESULTS: Compared to those in the highest tertile (≥14.3 ng/mL), the odds ratio (OR) for insulin resistance was 1.37 (95% confidence interval [CI], 1.01 to 1.86) for the 1st tertile (<9.7 ng/mL) and 1.19 (95% CI, 0.08 to 1.62) for the 2nd tertile (9.7 to 14.3 ng/mL) after adjusting for age, gender, waist circumference, alcohol consumption, smoking status, physical exercise, season, and cohort. After stratification of the subjects by adiposity, these associations remained only in non-obese subjects (lowest tertile vs. highest tertile, multivariable OR, 1.64; 95% CI, 1.05 to 2.56). CONCLUSION: Serum 25(OH)D has an independent inverse association with insulin resistance in the healthy, non-obese Korean population, even among people with vitamin D insufficiency.

The American College of Cardiology and the American Heart Association (ACC/AHA) 2013 joint guidelines for the treatment of hypercholesterolemia expand the indications for statin therapy. This study was performed to estimate the numbers of diabetic patients indicated for statin therapy according to the Third Adult Treatment Panel (ATP-III) of the National Cholesterol Education Program guidelines and the new ACC/AHA guidelines in Korea. We analyzed the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012. Patients with diabetes over 30 yr of age were analyzed by the two guidelines. Of the total 1,975 diabetic patients, only 377 (19.1%) were receiving drugs for dyslipidemia. Among 1,598 patients who had not taken any medications for dyslipidemia, 65.6% would be indicated for statin therapy according to the ATP-III guidelines. When we apply the new guidelines, 94.3% would be eligible for statin therapy. Among the total diabetic patients, the new guidelines, compared with the ATP-III guidelines, increase the number eligible for statin therapy from 53.1% to 76.2%. The new guidelines would increase the indication for statin therapy for most diabetic patients. At present, many diabetic patients do not receive appropriate statin therapy. Therefore efforts should be made to develop the Korean guidelines and to ensure that more diabetic patients receive appropriate statin therapy.

OBJECTIVES: The aim of this retrospective study was whether serum Tg predicts malignancy in follicular or Hurthle-cell neoplasms on fine needle aspiration. METHODS: A chart review of 111 patients (90 females, 21 males; mean age 46.8 +/- 11.9 years) with follicular or Hurthle-cell neoplasms on fine needle aspiration, who were surgically treated between Sep. 2001 and Sep. 2011, was performed. Predictive factors for malignancy were identified by the chi-squared test and multivariate logistic regression. RESULTS: There were no differences between 41 malignant and 70 benign lesions in serum Tg or any of the normalized indexes. Receiver-operator characteristic analysis revealed no cut-off value. Lesions with serum Tg levels greater than 500 g/L had no significant difference. And also there were no independent predictors of malignancy by multivariate logistic regression. CONCLUSIONS: In this study, the author found that serum Tg has poor accuracy for predicting malignancy in follicular or Hurthle cell neoplasms on fine needle aspiration.
