Abstract PDF Supplementary Material PubReader ePub: Background
The onset and progression of sarcopenia are highly variable among individuals owing to genetic and environmental factors. However, there are a limited number of studies measuring the heritability of muscle strength in large numbers of parent-adult offspring pairs. We aimed to investigate the familial correlation and heritability of hand grip strength (HGS) among Korean adults.
Methods
This family-based cohort study on data from the Korea National Health and Nutrition Examination Survey (2014 to 2019) included 5,004 Koreans aged ≥19 years from 1,527 families. HGS was measured using a digital grip strength dynamometer. Familial correlations of HGS were calculated in different pairs of relatives. Variance component methods were used to estimate heritability.
Results
The heritability estimate of HGS among Korean adults was 0.154 (standard error, 0.066). Correlation coefficient estimates for HGS between parent-offspring, sibling, and spouse pairs were significant at 0.07, 0.10, and 0.23 (P<0.001, P=0.041, and P<0.001, respectively). The total variance in the HGS phenotype was explained by additive genetic (15.4%), shared environmental (11.0%), and unique environmental (73.6%) influences. The odds of weak HGS significantly increased in the offspring of parents with weak HGS (odds ratio [OR], 1.69–3.10; P=0.027–0.038), especially in daughters (OR, 2.04–4.64; P=0.029–0.034).
Conclusion
HGS exhibits a familial correlation and significant heritable tendency in Korean adults. Therefore, Asian adults, especially women, who have parents with weak HGS, need to pay special attention to their muscle health with the help of healthy environmental stimuli.

Background
Results regarding the cardiovascular (CV) effects of dipeptidyl peptidase-4 (DPP-4) inhibitors are inconsistent. This study aimed to assess the effects of teneligliptin, a DPP-4 inhibitor, on the risk of major CV outcomes in type 2 diabetes mellitus (T2DM) patients compared to sulfonylurea.
Methods
From January 1, 2015 to December 31, 2017, we conducted a retrospective cohort study using the Korean National Health Insurance Service database. A total of 6,682 T2DM patients who were newly prescribed DPP-4 inhibitors or sulfonylurea were selected and matched in a 1:1 ratio by propensity score. The hazard ratios (HRs) for all-cause mortality, hospitalization for heart failure (HHF), all-cause mortality or HHF, myocardial infarction (MI), stroke, and hypoglycemia were assessed.
Results
During 641 days of follow-up, the use of teneligliptin was not associated with an increased risk of all-cause mortality (HR, 1.00; 95% confidence interval [CI], 0.85 to 1.19), HHF (HR, 0.99; 95% CI, 0.86 to 1.14), all-cause mortality or HHF (HR, 1.02; 95% CI, 0.90 to 1.14), MI (HR, 0.90; 95% CI, 0.68 to 1.20), and stroke (HR, 1.00; 95% CI, 0.86 to 1.17) compared to the use of sulfonylurea. However, it was associated with a significantly lower risk of hypoglycemia (HR, 0.68; 95% CI, 0.49 to 0.94) compared to sulfonylurea therapy.
Conclusion
Among T2DM patients, teneligliptin therapy was not associated with an increased risk of CV events including HHF, but was associated with a lower risk of hypoglycemia compared to sulfonylurea therapy.

Background

Metformin is considered the first choice oral treatment for type 2 diabetes patients in the absence of contraindications. Rarely, life-threatening complications associated with metformin treatment are seen in some patients with underlying diseases. The aim of this study was to further investigate the clinical profiles and risk factors for metformin-associated lactic acidosis (MALA) and the treatment modalities according to survival.

Methods

To identify MALA, we performed a retrospective study in seven diabetic patients who were taking metformin and had been diagnosed with lactic acidosis at Inha University Hospital between 1995 and 2012. For each patient, we recorded the age, sex, daily metformin dosage, laboratory test results, admission diagnosis, and risk factors. Also, concurrent conditions, treatment modalities, and outcomes were evaluated.

Results

Six patients had risk factors for lactic acidosis before admission. All patients had renal impairment on admission as a precipitating risk factor. Five patients survived and two patients died despite early renal replacement therapy. Older patients tended to have a poorer prognosis.

Conclusion

Renal function must be monitored in elderly type 2 diabetes mellitus patients with underlying diseases and conditions causing renal impairment who begin metformin treatment. Accurate recognition of MALA and initiation of renal replacement are essential for treatment.

Abstract PDF

BACKGROUND
New onset diabetes is a major complication after kidney transplantation. However, the natural course of posttransplantation diabetes mellitus (PTDM) remains unclear. The aim of this study was to demonstrate the detailed natural courses of PTDM according to the onset and persistency of hyperglycemia, and to investigate risk factors for development of different courses of PTDM in renal allograft recipients. METHODS: A total of 77 renal allograft recipients without previously known diabetes were enrolled and performed a serial 75 g oral glucose tolerance test at 0, 1, and 7 years after kidney transplantation. Patients were classified according to the onset and persistency of PTDM: early PTMD (E-PTDM), late PTDM (L-PTDM), persistent PTDM (P-PTDM), transient PTMD (T-PTDM), and non-PTDN (N-PTDM). RESULTS: The incidence of each group was as follows: E-PTDM, 39%; L-PTDM, 11.7%; P-PTDM, 23.4% T-PTDM, 15.6%; N-PTDM, 49.3%. Tacrolimus and female gender were associated with the development of E-PTDM. Among E-PTDM, age at transplantation was a high risk factor for the development of P-PTDM. Higher BMI at year1 was associated with the development of L-PTDM. CONCLUSION: Different risk factors were associated with various natural courses of PTDM. Since old age and female gender are not modifiable risk factors, it may be important to modify immunosuppressive therapy regimens for the prevention of E-PTDM and control of body weight for L-PTDM.

Abstract PDF

BACKGROUND
Anaplastic thyroid carcinoma represents 2% to 5% of all thyroid cancers and it is one of the most aggressive human cancers. Local extension at the time of diagnosis and distant metastases are almost always the rule. Its lethality is evidenced by a 5-year survival rate of 3.6% and a median survival time of 4 months. We retrospectively reviewed patients with this disease at 4 tertiary referral centers. METHODS: From 1990 to 2003, 19 cases(9 men and 10 women, mean age: 65.1+/-7.1 years) of anaplastic thyroid carcinoma were reviewed via the medical records. The overall survival rates according to the prognostic factors and the treatment modalities were analyzed. RESULTS: The presenting symptoms included rapidly enlarged neck masses in 16 patients, shortness of breath in 3 patients, hoarseness in 4 patients, dysphagia in 2 patients and chest wall pain in 1 patient. The mean diameter of tumor was 7.2cm. Local extension was seen in all of the cases that had undergone surgery. Distant metastases(lung 6, bone 2, abdominal carcinomatosis 2, brain 1 and mediastinum 1) were seen in 9 patients. Surgical treatment was performed in 10 patients. Radiotherapy was performed in 9 patients and chemotherapy was done in 5 patients; radiotherapy was performed alone in 2 patients, combination chemo-radiotherapy was performed in 3 patients, postoperative radiotherapy was performed in 2 patients and postoperative combination chemo-radiotherapy was performed in 2 patients. 4 patients were treated cons ervatively after the confirmative diagnosis. The overall median survival time was 123 days(range: 23~621 days); the median survival time was 129 days in the treatment group(n=15), and 27 days in the no treatment group (n=4), and significantly higher survival rates were observed for the treated patients(p=0.02). According to the treatment modalities, patients who underwent surgical treatment and postoperative radiotherapy and/or chemotherapy were observed to have significantly higher survival rates than patients in the radiotherapy and/or chemotherapy group(p=0.03), and also than those patients in the surgical treatment only group(p=0.04). CONCLUSION: We found that aggressive surgical treatment and postoperative radiotherapy and/or chemotherapy improved the survival rates of patients with anaplastic thyroid carcinoma even though local invasion and distant metastases was generally observed to occur

Abstract PDF

Multiple endocrine neoplasia type 1(MEN 1) is an autosomal dominantly inherited syndrome, characterized by the combined occurrence of tumors of the parathyroid glands, endocrine pancreas, and anterior pituitary gland. The MENIN gene, which is a kind of tumor suppressor gene, is located at the chromosomal locus 11q13. It consists of one untranslated exon and nine exons encoding the menin protein. We report a case of a 22-yearss-old woman with MEN type 1, who was proven to have a mutation in the MENIN gene. The patient was admitted because of repeated hypoglycemia. The fasting plasma glucose level was 32mg/dL. Seventy two hours fasting test showed an the insulin/glucose ratio as 0.33. Endoscopic ultrasonography detected multiple masses on the pancreas. The arterial -stimulated venous sampling(ASVS) with calcium showed sudden step up of insulin at the head and tail portions of the pancreas. The sellar MRI showed a pituitary mass that produced prolactin. Instead of a pathologic diagnosis from operational specimen, the genetic analysis revealed a mutation in the MENIN 1 gene(exon 2, 200~201insAGCCC).

Abstract PDF: BACKGROUND
The aim of this study was to examine the association between the common polymorphisms of the adiponectin gene(ACDC) and the intima-media thickness(IMT) of the common carotid arteries in type 2 diabetic patients. METHODS: The B mode ultrasound examination of carotid artery was performed on 133 type 2 diabetic patients. The carotid IMT was calculated using the Intimascope computer program. The SNP45 and SNP276 of the ACDC were examined. RESULTS: There was no significant difference in the carotid IMT among the SNP45 genotypes(0.66+/-0.18mm for TT, 0.71+/-0.12mm for TG and 0.64+/-0.15mm for GG, P=NS). Subjects carrying the SNP276 GG genotype had a markedly lower serum adiponectin concentration than those carrying the TT genotype(3.35+/-2.00microgram/mL vs. 4.98+/-2.24microgram/mL, P=0.029) The carotid IMT was significantly higher in patients with the SNP276 GG genotype than those with the TT genotype (0.70+/-0.17mm vs. 0.59+/-0.13mm, P=0.032). Patients with the +45GG/+276GG genotype combination showed significantly higher mean carotid IMT than the other genotype combinations(0.78+/-0.09mm vs. 0.71+/-0.15mm, P=0.013) CONCLUSIONS: These results suggest that the adiponectin gene, SNP276 is associated with the carotid IMT in type 2 diabetic patients. Further studies are will be needed to confirm these genotypephenotype associations.

Abstract PDF: Pendred syndrome is an autosomal recessive genetic disorder, which is characterized by sensorineural hearing loss, goiter and a positive perchlorate discharge test. It is caused by mutations of the PDS gene, and its clinical characteristics vary widely. The thyroid function in most cases is normal, or shows only mild hypothyroidism. In Pendred syndrome, there is an organification defect that leads to defective thyroid hormone synthesis, followed by chronic TSH stimulation. Herein is reported a case of a follicular thyroid carcinoma associated with Pendred syndrome. To our knowledge, this is the first case reported in Korea. The patient presented with a huge anterior neck mass, sensorineural hearing loss and a positive perchlorate discharge test. Fine needle aspiration cytology suggested malignancy of the thyroid, and a total thyroidectomy, with central compartment node dissection, was performed. The pathology from the thyroid mass showed a poorly differentiated follicular thyroid carcinoma

Abstract PDF: Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if left untreated. It is caused by germline mutations of the adenomatous polyposis coli (APC) gene, which has been mapped on chromosome 5q21, and is accompanied by various benign and malignant extracolonic manifestations. The prevalence of thyroid tumors developing in patients with FAP is about 1~2%, are associated with FAP and have certain characteristics; mean age of tumor diagnosis at less than 30 years of age, the pathology is the papillary histiotype in more than 90% of cases, including a so-called cribriform- morular pattern, and multifocality is a frequent feature. In a genetic analysis, thyroid cancer in FAP usually has a mutation in the 5-portion of exon 15 between 778 and 1309, on chromosome 5q21. Also, the ret/PTC (especially ret/PTC1 and ret/PTC3) and p53 genes are thought probably to be associated with thyroid cancer in FAP patients. A case of familial adenomatous polyposis, accompanied by thyroid papillary cancer, was experienced in a 29 year-old female. She had hundreds of adenomas throughout the entire colon and congenital hypertrophy of the retinal pigment epithelium (CHRPE). The pathological finding of thyroid cancer was revealed as a mixture of cribriform, trabecular and papillary patterns. In a genetic analysis, she and her brother had a germline mutation of the APC gene at codon 1309. In Korea, there has been no previous case of cribriform-morular pattern and familial genetic analysis in FAP associated with thyroid cancer.

Abstract PDF: In this report, a 70-year-old female patient was detected with laboratory findings of hypercalcemia. The most common causes of hypercalcemia are primary hyperparathyroidism and malignant disease. Her laboratory tests did not show any evidence for neither primary hyperparathyroidism nor malignant diseases. Thus, granulomatous disease was suspected as the cause of the hypercalcemia. Liver MRI (magnetic resonance image) was performed on the subject, which suggested the presence of hepatic tuberculosis and sarcoidosis. Because the chest x-ray did not show a definite tuberculous lesion, we performed a laparoscopic liver biopsy for a final diagnosis. Findings from the biopsy specimen showed typical tuberculosis. After treatment with tuberculosis medication, hypercalcemia of the subject was resolved. Hypercalcemia is a well recognized as a possible complication of active pulmonary tuberculosis. But one should consider hepatic tuberculosis without pulmonary tuberculosis as a cause of hypercalcemia.
