Long-term outcome of Bartter syndrome in 54 patients: A multicenter study in Korea.

Introduction: Bartter syndrome (BS) is a rare salt-wasting tubulopathy caused by mutations in genes encoding sodium, potassium, or chloride transporters of the thick ascending limb of the loop of Henle and/or the distal convoluted tubule of the kidney. BS is characterized by polyuria, failure to thrive, hypokalemia, metabolic alkalosis, hyperreninemia, and hyperaldosteronism. Potassium and/or sodium supplements, potassium-sparing diuretics, and nonsteroidal anti-inflammatory drugs can be used to treat BS.

Factors Associated With Post-traumatic Growth Among Healthcare Workers Who Experienced the Outbreak of MERS Virus in South Korea: A Mixed-Method Study.

Infectious disease outbreaks such as COVID-19 and MERS pose a major threat to healthcare workers' (HCWs) physical and mental health. Studies exploring the positive changes gained from adapting to traumatic events, known as post-traumatic growth (PTG), have attracted much attention. However, it is unclear which factors or experiences lead to PTG among HCWs.

Nursing students' knowledge, attitude, self-efficacy in blended learning of cardiopulmonary resuscitation: a randomized controlled trial.

Background: Although various forms of online education are on the rise worldwide, effects of such innovative approach are yet to be validated. This study analyzes whether blended learning cardiopulmonary resuscitation (CPR) education that integrates e-learning and face-to-face education is effective in improving nursing students' knowledge, attitude, and self-efficacy.

Methods: A randomized controlled design was used.

The Effects of Menopausal Hormone Therapy on Serum Level of C-reactive Protein in Postmenopausal Korean Women.

Objectives: Inflammation is a major mechanism underlying coronary heart disease (CHD) and C-reactive protein (CRP) is a marker of inflammation. When administered soon after menopause, menopausal hormone therapy (MHT) prevents CHD. This study was conducted to examine the impact of estrogen by administration route on CRP in postmenopausal Korean women using micronized progesterone (MP4) for endometrial protection.

Higher Incidence of BK Virus Nephropathy in Pediatric Kidney Allograft Recipients with Alport Syndrome.

A retrospective review was performed to assess the risk factors and outcomes of BK virus infection and nephropathy (BKVN), an early complication in pediatric kidney allograft recipients. The study investigated the incidence, risk factors, and clinical outcomes of BK viremia and BKVN in a Korean population of pediatric patients who received renal transplantation from 2001-2015 at the Seoul National University Hospital. BKVN was defined as biopsy-proven BKVN or plasma BK viral loads >10,000 copies/mL for >3 weeks.

Clinical Significance of Crescent Formation in IgA Nephropathy - a Multicenter Validation Study.

Background/aims: Additional validation study was warranted to confirm the clinical significance of C score, which was recently added to the Oxford classification for immunoglobulin A nephropathy (IgAN).

Methods: We performed a multicenter retrospective cohort study in four hospitals in Korea. Patients who had biopsied glomeruli less than eight or inadequate follow-up information were excluded.

Reninoma: a rare cause of curable hypertension.

The most common type of refractory hypertension found in children is secondary hypertension, which is a potentially curable disease. Reninoma, a renin-secreting juxtaglomerular cell tumor, is a rare cause of severe hypertension that is usually diagnosed in adolescents and young adults. Surgical resection of the tumor completely cures the hypertension of patients with reninoma.

Three cases of multicentric carpotarsal osteolysis syndrome: a case series.

Background: Multicentric carpotarsal osteolysis syndrome (MCTO) is characterized by progressive destruction and disappearance of the carpal and tarsal bones associated with nephropathy. MCTO is caused by loss-of-function mutations in the MAF bZIP transcription factor B (MAFB) gene.

Case Presentation: This report describes three unrelated patients with MAFB mutations, including two male and one female patient.

Genotype-Phenotype Analysis in Pediatric Patients with Distal Renal Tubular Acidosis.

Background/aims: Primary distal renal tubular acidosis (dRTA) in children is a rare genetic disorder, and three causative mutated genes have been identified: SLC4A1, ATP6V1B1, and ATP6V0A4. We analyzed the prevalence and phenotypic differences of genetic mutations in children with dRTA.

Methods: A total of 17 children with dRTA were enrolled in the study.

Associations between working environment and weight control efforts among workers with obesity in Korea.

Objective The aim of this study was to investigate the relationship between working environment and weight control efforts among obese workers in Korea. Methods This study was based on the 2011 3rd Korean Working Conditions Survey, which was conducted on workers aged 15 years or older. A sample of 484 obese workers was included in the study.

Associations between Social and Physical Environments, and Physical Activity in Adults from Urban and Rural Regions.

Objectives: This study investigates investigated the relationship between social and physical environments, and moderate to vigorous physical activity (MVPA) amongst adults in both rural and urban areas within Korea.

Methods: A sample of 128,735 adults from the 2013 Community Health Survey (CHS) was analyzed using a multilevel logistic analysis.

Results: Urban residents with higher satisfaction in public transportation satisfaction and rural residents with more access to sports parks, hiking trails, and bike cycle paths were more likely to be active.

Long-term repeated rituximab treatment for childhood steroid-dependent nephrotic syndrome.

Background: Rituximab (RTX) can be used as a rescue therapy for steroid-dependent nephrotic syndrome (SDNS). However, the efficacy and safety of long-term, repeated use of RTX are not established. This study was conducted to assess the efficacy and safety of long-term, repeated RTX treatment in children.

Three cases of Gordon syndrome with dominant KLHL3 mutations.

Background: Gordon syndrome (GS) is a rare form of monogenic hypertension characterized by low renin hypertension, hyperkalemia, hyperchloremic metabolic acidosis, and normal glomerular filtration rate. To date, four genes causing GS have been identified as: WNK1, WNK4, CUL3, and KLHL3.

Case Presentation: We report three cases of GS in two families.

Genotype and Phenotype Analysis in Pediatric Patients with Cystinuria.

Cystinuria is an inherited disorder characterized by defective renal reabsorption of cystine and dibasic amino acids leading to nephrolithiasis. This study was conducted to analyze the genotypes and phenotypes of pediatric patients with cystinuria. Eight children from Seoul National University Hospital and Asan Medical Center presenting with cystinuria from January 2003 to June 2016 were retrospectively analyzed.
