Analysis of intake trends of kimchi, fruits and vegetables (1998–2020) and factors associated with the intake (2016–2020): based on the Korea National Health and Nutrition Examination Survey / 한국영양학회지

Purpose@#This study aimed to analyze the trends in kimchi, vegetable, and fruit consumption among the Korean population and identify the factors associated with this consumption.The goal was to provide fundamental data for developing appropriate guidelines to increase kimchi consumption by understanding its characteristics. @*Methods@#The analysis utilized data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 1998 and 2020. A total of 81,680 adults, aged 30 years or older, were included in the trend analysis. For the analysis of factors associated with kimchi, vegetable, and fruit intake, a subgroup of 22,122 adults aged 30 years or older from the KNHANES (2016-2020) was divided into two groups: 30–64 years old and 65 years old or older. Since the KNHANES data employed a complex sampling design, the statistical analysis was conducted using the appropriate complex sampling design method. @*Results@#The overall consumption of kimchi exhibited a declining trend among both men and women. Specifically, there was a significant decline in the intake of baechu kimchi among both genders. The decline in kimchi consumption above the standard was associated with a decrease in meal frequency and an increase in the frequency of eating alone. However, the patterns for unsalted vegetables and fruits differed compared to kimchi. @*Conclusion@#In this study, there was a decline in kimchi consumption among both men and women, and the potential factors associated with this trend included Westernized dietary habits, the presence of a spouse who influenced dietary habits, and an increased frequency of solitary dining due to the rise in single-person households. Therefore, it is necessary to develop dietary guidelines that consider these factors.

Radiopharmaceuticals Used in Cardiac Imaging / 핵의학분자영상

Many radiopharmaceuticals have been developed and wildy used in the imaging cardiac function. Myocardial perfusion imaging (MPI) is a well established noninvasive method of assessing coronary blood flow and has been widely used in patients diagnosed or suspected with coronary artery diseases. The innovation of radiopharmaceuticals used in the cardiac imaging is one of the most important contributors to the development of nuclear cardiology. Thallium-201 and various technetium-99m agents have been globally used for myocardial perfusion SPECT, and N-13 ammonia (13NH3), rubidium-82 (82Rb), O-15 water (H215O) for myocardial perfusion PET. As well as the cardiac perfusion studies, new radiopharmaceuticals that visualize fat metabolism or receptors of the sympathetic nervous system have successfully been applied to clinical practice. Useful information can be obtained for diagnosing coronary artery disease, evaluating patients' condition, or assessing therapeutic effects. In this review, we describe the characteristics and clinical usefulness of radiopharmaceuticals used for cardiac SPECT and PET.

Two Cases of Pregnancies Complicated with Central Diabetes Insipidus / 대한산부인과학회지

Diabetes insipidus is an unusual cause of urinary frequency during pregnancy. It occurs in 2 to 6 per 100,000 pregnancies. It is a disorder in which the abnormal secretion, degradation, or activity of vasopressin cause hypotonic polyuria, polydipsia, and dehydration. And this syndrome appears to be associated with multiple gestations, preeclampsia, and abnormal liver function. We report two cases of pregnancies complicated with diabetes insipidus. One patient was diagnosed during pregnancy and DDAVP (L-deamino-8-d-arginine vasopressin) was used to manage diabetes insipidus. The other patient was diagnosed before pregnancy and DDAVP was not used.

The Influence of Embryo Transfer Catheter on the Outcome of In Vitro Fertilization and Embryo Transfer / 대한산부인과학회잡지

OBJECTIVE: To compare the efficacy of two different embryo transfer catheters, Norfolk and Wallace, in terms of the outcome of in vitro fertilization and embryo trabsfer (IVF-ET). METHODS: One hundred and seventy-one IVF-ET cycles performed in 132 infertile couples were included in this retrospective study. The couples were subjected to two different embryo transfer catheter types: Norfolk catheter group (92 cycles) and Wallace catheter group (79 cycles). Controlled ovarian hyperstimulation (COH) was performed using step-down protocol with GnRH agonist or antagonist. Four or less embryos were transferred on day 2 or 3 after oocyte retrieval. The luteal phase was supported by intramuscular progesterone (Progest) or intravaginal 8% progesterone gel (Crinone). RESULTS: The pregnancy rate per ET and the implantation rate were significantly higher in Wallace catheter group, respectively (20.7% vs. 34.2%, p=0.047; 9.7% vs. 15.1%, p=0.047). No statistically significant differences were observed in the other parameters between the two groups. CONCLUSION: The Wallace catheter showed better IVF-ET outcomes when compared with the Norfolk catheter in our study. Further prospective randomized controlled studies in a larger scale will be necessary to confirm our findings.

Annual Report on External Quality Assessment in Diagnostic Genetics in Korea (2003) / 임상검사와정도관리

The importance of quality control for dramatically growing genetic tests continues to be emphasized with increasing clinical demands. Diagnostic genetics subcommitee of KSQACP performed two trials for cytogenetic study in 2003. Cytogenetic surveys were performed by 33 laboratories and answered correctly in most laboratories except some problems in nomenclature and analysis for FISH and complex cytogenetic abnormalities in neoplasia. The molecular genetic test surveys include M. tuberculosis, HBV, HPV, leukemia/lymphoma, ApoE genotyping, Duchenne muscular dystrophy, myoclonic epilepsy and ragged red muscle fibers, and spinal and bulbar muscular atrophy. HPV, myoclonic epilepsy and ragged red muscle fibers, and spinal and bulbar muscular atrophy were the first challenge of the genetic survey. Molecular genetic survey showed excellent results in most participants, however, HPV tests should be improved by quality control in a few laboratories. External quality assessment program for cytogenetic analysis could be helpful to give participants many chances of continuous education and of interesting case materials.

The importance of quality control for dramatically growing genetic tests continues to be emphasized with increasing clinical demands. Diagnostic genetics subcommitee of KSQACP performed two trials for cytogenetic study in 2002. Cytogenetic surveys were performed by 33 laboratories and answered correctly in most laboratories except some problems in nomenclature and analysis for mosaicism and cytogenetics of neoplasia. The molecular genetic test surveys include M. tuberculosis, HCV, HBV, leukemia/lymphoma, ABO genotyping, ApoE genotyping, spinocerebellar ataxia (SCA), spinal muscular atrophy (SMA), and mitochondrial encephalomyopathy, lactic acidosis, and stroke like episodes (MELAS). HBV, SCA, SMA, MELAS tests were the first challenge of the genetic survey. Molecular genetic survey showed excellent results in most participants, however, ABO genotyping tests should be improved by new methods in a few laboratories. External quality assessment program for diagnostic genetics could be helpful to give participants many chances of continuous education and of interesting case materials.

A case of typhlitis developed after anticancer chemotherapy in a patient with solid tumor / 대한내과학회지

Typhlitis is a necrotizing enterocolitis of the cecum, ascending colon and terminal ileum. Typhlits has been reported in the severely neutropenic patients and likely results from a combination of neutropenia and defects in the bowel mucosa related to cytotoxic chemotherapy. This disease is most common in patients with leukemia who have undergone intensive myeloablative chemotherapy. Presumptive diagnostic criteria for typhlitis include fever, abdominal pain and tenderness, and radiologic evidence of right-sided colonic inflammation in patients with neutropenia. Recently, this disease is also reported in patients with solid tumor due to increasing challenges of high dose chemotherapy. We report a case of typhlitis developed in the circumstance of neutropenia induced by chemotherapy in a patient with malignant testicular tumor.

Bleeding from a Tuberculous Gastric Ulcer in a Hemodialysis Patient / 대한신장학회잡지

The incidence of Tuberculosis among the patients with end-stage renal disease(ESRD) has increased up to 16 times of that in the general population. The impairment of the cellular immunity in the ESRD patients may have a role in the pathogenesis. Extrapulmonary tuberculous manifestations such as lymph node, peritoneum, and pleura involvement are more frequent in the ESRD patients than in the general population. However, there has been no case of upper gastrointestinal(UGI) bleeding as a result of a gastric tuberculosis in the ESRD patient on hemodialysis. Here we report an unusual case of a hemodialysis patient with UGI bleeding secondary to a tuberculous gastric ulcer. A 31-year-old female on hemodialysis was admitted with melena. Endoscopy revealed a benign gastric ulcer with a visible bleeding vessel at the base, located in the anterior wall of the antrum. An exploratory laparotomy showed multiple, round, small and yellow nodules on the visceral peritoneum as well as a 1-cm sized gastric ulcer. After gastric resection, a histological examination including peritoneal nodules demonstrated chronic granulomatous inflamation with caseous necrosis and giant cells. The patient has been on antituberculosis medication and followed up in the outpatient department without any event for 8 months.
