Background: The out-of-pocket maximum is one of the distinctive healthcare systems which sets a ceiling on co-payment in order to reduce the burden of households from the unpredictable medical expenditure. However, this leads to an increase in the demand for healthcare services especially in long-term care hospitals (LTCHs) in Korea. Methods: This study analyzed the influence factor of medical service overuse of 165,592 inpatients in LTCHs which out-of-pocket maximum is applied, by utilizing data from the National Health Insurance Service (2016). Based on Anderson Model, the medical service overuse, as a dependent variable, was defined as long-stay admission more than 180 days at the LTCHs. Independent variable was comprised of predisposing factors (gender, age), enabling factors (income level, types of out-of-pocket maximum) and need factors (illness level, patient use of tertiary hospital). Results: The most powerful factor of medical service overuse in LTCHs was availability of pre-payment for the out-of-maximum (odds ratio [OR], 191.66; p<0.001). This tendency was found in high income level status (p<0.001). Furthermore, mild inpatients (OR, 1.50; p<0.001) which had no experience with the tertiary hospitals (OR, 2.06; p<0.001) were more relevant to the medical service overuse in LTCHs, compared to the severe inpatients. Conclusion It is suggested that a separate standard of out-of pocket maximum with regards to LTCHs is required to secure the beneficial functions of long-term hospitals and prevent unnecessary financial leakage to achieve sustainable and financially sound National Health Insurance.

Pre-eclampsia is known to cause considerable maternal morbidity and mortality. Thus, many studies have examined the etiopathogenesis of pre-eclampsia. While many pathophysiological factors related to pre-eclampsia have been identified, the precise etiopathogenesis of pre-eclampsia remains unclear. Numerous studies have identified factors for the early prediction for pre-eclampsia to lead to preparation and closer observation on pre-eclampsia when it occurs. This article reviews on current studies of biomarkers and genetic factors related to pre-eclampsia, which may be important for developing strategies for early prediction of pre-eclampsia.

There are various causes to a low level of consciousness in patients in the intensive care unit. Neurological injury, infection, and metabolic disarray are considered as some of the causes. A 39 year-old female patient was transferred to our hospital with septic shock due to ascending colon perforation. The patient had previously received ovarian cancer surgery and a cycle of chemotherapy at another hospital. Emergent operation for colon perforation was successful. After the operation, she was treated in the intensive care unit for infectious and pulmonary complications. She suddenly showed deterioration in her level of consciousness and had a generalized seizure. At the time of her seizure, she had severe hyperammonemia. Brain CT showed severe cerebral edema that was absent in the CT scan taken 2 days before. Continuous renal replacement therapy was conducted but was ineffective in lowering the level of serum ammonia and the patient subsequently died.

Percutaneous nephrolithotomy (PCNL) has largely replaced open surgical intervention for the management of renal pelvis calculi as it reduces patient morbidity and shortens hospital stay. However, major complications such as hydrothorax or pneumothorax can be encountered uncommonly. A 64-year-old, 48 kg, female patient underwent PCNL under general anesthesia. The preoperative chest X-ray showed normal findings. Elevated airway pressure was noted and then breathing sounds were not audible on the right lung field during the procedure. A chest X-ray and chest computerized tomographic scan, taken immediately after the operation, showed massive hydrothorax and total collapse in the right lung. After drainage of the pleural effusion via chest tube, the patient recovered completely. Anesthesiologists should be aware that hydrothorax can occur during the PCNL procedure and must be prepared to intervene quickly.

Infants with Sandhoff disease typically appear normal until 3–6 months of age. As the disease progresses, they present with symptoms such as loss of motor skills, exaggerated startle response to loud noise, seizures, visual loss, and paralysis. We encountered a rare case of a 22-month-old girl with Sandhoff disease characterized by progressive motor weakness and dysphagia, who initially showed signs of aspiration at 20 months of age. The major problems related to dysphagia were oromotor dysfunction and abnormal feeding posture. Within 3 months of identification of difficulty in swallowing, the patient showed a significant decrease in food intake, with rapid deterioration of nutritional status. We report our case with a review of the literature.

BACKGROUND/OBJECTIVES: Dietary factors are important contributors to cardiometabolic and cancer mortality. We examined the secular trends of nine dietary factors (fruits, vegetables, whole grains, nuts and seeds, milk, red meat, processed meat, sugar-sweetened beverages, and calcium) and the associated burdens of cardiometabolic and cancer mortality in Korea using representative cross-sectional survey data from 1998 to 2016. SUBJECTS/METHODS: Using dietary data from Korean adults aged ≥ 25 years in the Korea National Health and Nutrition Examination Survey (KNHANES), we characterized secular trends in intake levels. We performed comparative risk assessment to estimate the population attributable fraction and the number of cardiometabolic and cancer deaths attributable to each dietary factor. RESULTS: A total of 231,148 cardiometabolic and cancer deaths were attributable to nine dietary risk factors in Korea from 1998 to 2016. Suboptimal intakes of fruits and whole grains were the leading contributors. Although the intakes of fruits, vegetables, and whole grains moderately improved over time, the intake levels in 2016 (192.1 g/d, 225.6 g/d, and 10.9 g/d, respectively) remained far below the optimal levels. Deaths attributable to the low intakes of nuts and seeds (4.5 g/d), calcium (440.5 mg/d), and milk (37.1 g/d) and the high intakes of red meat (54.7 g/d), processed meat (4.7 g/d), and sugar-sweetened beverages (33.0 g/d) increased since 1998. Compared with older age groups (≥ 45 years), more unfavorable changes in dietary patterns were observed in the younger population aged 25–44 years, including more sharply increased intakes of processed meat. CONCLUSIONS We observed improvement in the intakes of fruits, vegetables, and whole grains and unfavorable changes in the intakes of processed meat and sugar-sweetened beverages over the past few decades. Our data suggest that to reduce the chronic disease burden in Korea, more effective nutritional policies and interventions are needed to target these dietary risk factors.

PURPOSE: We aimed to evaluate the association between immunoglobulin G (IgG) at birth and late-onset sepsis (LoS) in preterm infants. METHODS: Medical records of very-low-birth-weight infants, born at gestational age <28 weeks, between 2013 and 2016, were retrospectively reviewed. Subjects were divided into two groups based on the occurrence of LoS (LoS vs. non-LoS), and IgG levels at 1 day, and at 2 weeks and 4 weeks after birth were investigated. IgG levels, other perinatal factors, and clinical factors were compared in the two groups. The relationship between IgG levels and mortality among infants in the LoS group was also analyzed. RESULTS: A total of 105 infants were analyzed after exclusion of cases with early onset sepsis or death at < 72 hours of life. Gestational age in the LoS group was lower than in the non-LoS group (25.0±1.8 vs. 26.3±1.4 weeks, P=0.004). IgG levels at birth were similar between the two groups (236.4±96.4 vs. 282.0±104.7 mg/dL, P=0.078). Multivariate analysis showed that IgG at birth was not an independent risk factor for LoS. In the LoS group, IgG levels at birth were comparable between survivors and cases involving mortality. CONCLUSION: IgG levels at birth were not associated with the occurrence of LoS in extremely preterm infants.

PURPOSE: To evaluate the effects of exclusive breast milk feeding (BMF) on the incidence of necrotizing enterocolitis (NEC) in preterm infants. METHODS: All newborn infants, born at <32 weeks of gestation and weighing <1,500 g, admitted to the neonatal intensive care center at Seoul National University Bundang Hospital during the study period, were included. The study was divided into period I: pre-exclusive BMF (January 2010–March 2014) and period II: exclusive BMF (April 2014–December 2016). RESULTS: A total of 374 infants were enrolled in this study, with 174 in period I and 174 in period II. The incidence of NEC was 11.5% in period I and 3.4% in period II. As the mean gestational age and birth weight were significantly greater in infants in period II, the difference in the incidence of NEC between the two periods was adjusted by gestational age. After adjustment, the incidence of NEC in period II was significantly lower than in period I (P=0.024). CONCLUSION: Exclusive BMF significantly reduced the incidence of NEC in a single neonatal intensive care center.
