PURPOSE: The study was to explore the level of low back pain and characteristic factors influencing low back pain (LBP) and mental health during pregnancy. METHODS: The subjects were a total of 383 healthy pregnant women in S City and K-Do. Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlation. RESULTS: 82.5% of the pregnant women answered the existence of LBP and 19.7% of them had high LBP. The preferred method of controlling LBP was 'Just endure' (42.3%). There were significant differences in pregnancy level (p < .05) and discomfort condition related to pregnancy (p < .01) according to low back pain. There were significant differences in pain intensity according to mental health. The correlation between pain level and pregnancy weeks (p < .001) and BMI in previous pregnancy (p < .001) was significant. The correlation between mental health and age was significant (p < .001). CONCLUSION: The majority of the pregnant women experienced LBP during pregnancy. However, they were not offered the best method of controlling the pain. Thus, for preventing LBP during pregnancy, we recommend regular exercises and BMI control.

BACKGROUND: The differentiation of Mycobacterium tuberculosis (MTB) from nontuberculous mycobacteria (NTM) is of primary importance for infection control and choice of antimicrobial therapy. The diagnosis of diseases caused by NTM is difficult because NTM are prevalent in the environment and have fastidious properties. In this study, we evaluated the real-time PCR-based MTB/NTM detection kit for its usefulness in discrimination of MTB and NTM species. METHODS: A total of 155 sputum specimens whose AFB staining smear and culture were positive were used for this study. Among them, 59 and 96 samples had been identified as MTB and NTM, respectively. DNA obtained from sputum specimens was subjected to analysis with MolecuTech Real MTB-ID(R) (M&D, Korea) real-time PCR-based MTB/NTM detection kit. Subsequently, the results of MolecuTech Real MTB-ID(R) were compared with AFB staining smear and culture results. RESULTS: The positive rate of MolecuTech Real MTB-ID(R) to detect MTB and NTM was 98.3% (58/59) and 97.9 (94/96), respectively, using sputum specimens. CONCLUSION: For detection of MTB/NTM, the sensitivity and specificity of MolecuTech Real MTB-ID(R) were comparable to those of conventional methods. Therefore, this study suggests the usefulness of real-time PCR-based MolecuTech Real MTB-ID(R) for rapid detection of MTB/NTM from direct specimens.

Background: We aim to compare the clinical characteristics and subjectively reported symptoms of the acute coronavirus disease (COVID) phase and those of the post-acute COVID phase to examine varying factors that affect the number of persistent symptoms and their categories. Methods: We categorized 1,122 patients who visited the post coronavirus disease 2019 (COVID-19) clinic into two groups: “acute group” (< 4 weeks following diagnosis of COVID-19) and “post-acute group” (> 4 weeks following diagnosis of COVID-19). We statistically compared clinical characteristics between the two groups and determined which factors are associated with the number of persistent symptoms and their categories. Results: The persistent symptoms of post COVID-19 conditions were classified into three categories as follows: Category A (the prevalence of symptoms is higher in the acute-visit group than in the post-acute-visit group), Category B (the prevalence of symptoms is not different between the two groups) and Category C (the prevalence of symptoms is higher in the post-acute-visit group than in the acute-visit group). Category A mainly included respiratory symptoms. Category B had generalized weakness, weight loss, cardiologic symptoms, hypogeusia, hyposmia, anxiety, and various gastrointestinal symptoms. Category C included fatigue, decreased attention, depression, blurred vision, hair loss, and sexual dysfunction.Anxiety, depression, fatigue and age were also associated with the number of symptoms and their categories, and anxiety is the most correlated factor (P < 0.001) among them. Conclusion The persistent symptoms of post COVID-19 condition involve multi-organ and continue for four weeks or greater. Therefore, long-term observation and multidisciplinary interventions are essential for patients with post COVID-19 conditions.

Background: We aimed to investigate the factors associated with neurological manifestations of post-coronavirus disease 2019 (COVID-19) conditions. Methods: We retrospectively collected data from 440 patients who visited our post-COVID-19 clinic more than 4 weeks after severe acute respiratory syndrome coronavirus 2 infection. We analyzed the prevalence of different neurological symptoms (brain fog, memory impairment, headache, and dizziness) and assessed the associated factors. Results: Brain fog was the most common symptom, observed in 170 patients (38.6%), followed by headaches (n = 137, 31.1%), dizziness (n = 128, 29%), and memory impairment (n = 104, 23.6%). Brain fog was associated with hyposmia or hypogeusia (odds ratio [OR], 2.54; P < 0.001), Fatigue Severity Scale (FSS) (OR, 1.06; P < 0.001), and Hospital Anxiety and Depression Scale-Anxiety (OR, 1.09; P = 0.037). Memory impairment was associated with sleep problems (OR, 2.83; P < 0.001), FSS (OR, 1.05; P < 0.001), and age (OR, 1.02; P = 0.015). Headache was associated with sleep problems (OR, 2.28; P= 0.001), sex (OR, 1.68; P = 0.042), and FSS (OR, 1.04; P < 0.001). Dizziness was associated with sleep problems (OR, 2.88; P < 0.001), and FSS (OR, 1.04; P < 0.001). The incidence of brain fog ( P < 0.001), memory impairment ( P < 0.001), dizziness (P = 0.007), and headache (P = 0.045) accompanied by hyposmia and hypogeusia was higher in patients with the aforementioned symptoms than in those without. Conclusion This study suggests that there is a relationship between neurological symptoms and other clinical factors, such as fatigue, depression, anxiety, hyposmia, and hypogeusia.

PURPOSE: Excess sodium intake may contribute to the etiology of hypertension and cardiovascular disease risk. World Health Organization (WHO) recommends a daily sodium intake of less than 2 g. The aim of this study was to estimate the association of sodium intake with obesity in Korean adults. METHODS: This study used Dietary intake and Health data on 22,321 subjects aged 30 years and over from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010~2014. Information on dietary intake was obtained by the one day 24-hour recall method in KNHANES, and sodium intake was classified into five groups (< 2,000 mg, 2,000~4,000 mg, 4,000~6,000 mg, 6,000~8,000 mg, ≥ 8,000 mg). Obesity was defined as having a body mass index (BMI) higher than 25 kg/m². Intake of sodium and obesity status were analyzed by logistic regression with SPSS Statistics 23. RESULTS: Men tended to have a higher sodium intake than women (p < 0.001). After adjusting for age, sex, year, daily energy intake, education level, smoking status, drinking status, physical activity, and chronic diseases and comparing the highest sodium intake group (≥ 8,000 mg) with the lowest intake group (< 2,000 mg), the OR of obesity was 1.351 (95% CI: 1.032~1.767) in men. The OR of obesity in the sodium intake group (4,000~6,000 mg) was 1.232 (95% CI: 1.063~1.427) in women. CONCLUSION: Our findings suggest an independent relationship between sodium intake and as increased risk of obesity in Korean adults, implying the necessity for future research on low-sodium diet intervention in relation to obesity.

Pulmonary embolism is a rare complication after percutaneous vertebroplasty for compression fracture. Embolization is related to cement leakage outside the treated vertebral body into the adjacent venous system. We report on a case of pulmonary embolism with bone cement in the right pulmonary artery in a 75-year-old female who had undergone percutaneous vertebroplasty 2 months before. Her simple X-ray of the spine captured polymethyl metacrylate leakage from the vertebral body, which indicated the pathophysiology of this event.

Aspergillus peritonitis is a rare but serious cause of peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients. We report 2 cases of peritonitis caused by Aspergillus niger in CAPD which were treated successfully with voriconazole and caspofungin, respectively, and catheter removal. Both patients initially received amphotericin B; however, they were not cured with the agent. We briefly discuss the proper selection of antifungal agent and the treatment duration. Previously reported cases of the CAPD peritonitis caused by A. Niger are also reviewed in this article.

Clinical criteria have been established for idiopathic hypereosinophilic syndrome (HES): persistent eosinophilia of 1500 eosinophils/mm3 for at least 6 months or death even within 6 months with signs and symptoms of HES; no evidence for parasitic, allergic, or other recognized causes of eosinophilia despite careful evaluation; and signs and symptoms of organ system involvement or dysfunction, such as congestive heart failure, hepatosplenomegaly, central nerveous system disease. Because cerebral hemorrhage in HES has not been reported yet in Korea, we report a case of hypereosinophilic syndrome with peripheral blood eosinophilia, with biopsies of skin and duodenum showing diffuse eosinophilic infiltration, and multiple organ dysfunction in a 49 year old man died of cerebral hemorrhage three months after the occurrence of the disease.

A qualitative systematic review was performed to identify associations of obesity and dyslipidemia with intake of sodium, fat, and sugar among Koreans. We reviewed 6 Korean research databases (KMbase, KoreaMed, NDSL, DBpia, RISS, KISS) with the keywords “sodium intake,”“fat intake,” and “sugar intake.” Total of 11 studies were investigated in this present study. Of these articles, 7 studies were related to sodium intake, 2 studies had a relation to fat intake, and 2 studies were associated with sugar intake. We indicated general characteristics, concentration of serum lipids, nutrition intake, and statistically significant results. High sodium intake contributed to increased etiology of hypertriglyceridemia, high-density lipoprotein (HDL) hypocholesterolemia, and a risk of being overweight. Fat intake was significantly associated with body fat, low-density lipoprotein (LDL) hypercholesterolemia, and HDL hypocholesterolemia. Sugar intake from coffee drinks and sugar-sweetened beverages contributed to increased HDL hypocholesterolemia and continuous metabolic syndrome score. This qualitative review among Koreans represented that intake of sodium, fat, and sugar has a positive relationship with cause of obesity-related diseases. Especially, this present study has a great significance in terms of considered study that intake of the potentially hazardous nutrients among Koreans has an association with obesity and dyslipidemia. However, further studies such as randomized controlled trials on associations between sodium, fat, and sugar and obesity and dyslipidemia need to be continuously required in order to conduct quantitative systematic reviews and a meta-analysis for Koreans.
