This observational study using nationwide data suggests that SSNHL is associated with an increased incidence of CCVD, specifically stroke. Therefore, patient surveillance for signs of CCVD should be considered for patients who receive a diagnosis of SSNHL.

From May through July 2015, a total of 26 cases of Middle East Respiratory Syndrome were reported from 2 hospitals in Daejeon, South Korea, including 1 index case and 25 new cases. We examined the epidemiologic features of these cases and found an estimated median incubation period of 6.1 days (8.8 days in hospital A and 4.6 days in hospital B). The overall attack rate was 3.7% (4.7% in hospital A and 3.0% in hospital B), and the attack rates among inpatients and caregivers in the same ward were 12.3% and 22.5%, respectively. The overall case-fatality rate was 44.0% (28.6% in hospital A and 63.6% in hospital B). The use of cohort quarantine may have played a role in preventing community spread, but additional transmission occurred among members of the hospital cohort quarantined together. Caregivers may have contributed in part to the transmission.

BackgroundThe sagittal alignment of the spine and pelvis is not only closely related to the overall posture of the body but also to the evaluation and treatment of spine disease. In the last few years, the EOS imaging system, a new low-dose radiation X-ray device, became available for sagittal alignment assessment. However, there has been little research on the reliability of EOS. The purpose of this study was to evaluate the intrarater and interrater reliability of EOS for the sagittal alignment assessment of the spine and pelvis.MethodsRecords of 46 patients were selected from the EOS recording system between November 2016 and April 2017. The exclusion criteria were congenital spinal anomaly and deformity, and previous history of spine and pelvis operation. Sagittal parameters of the spine and pelvis were measured by three examiners three times each using both manual and EOS methods. Means comparison t-test, Pearson bivariate correlation analysis, and reliability analysis by intraclass correlation coefficients (ICCs) for intrarater and interrater reliability were performed using R package “irr.”ResultsWe found excellent intrarater and interrater reliability of EOS measurements. For intrarater reliability, the ICC ranged from 0.898 to 0.982. For interrater reliability, the ICC ranged from 0.794 to 0.837. We used a paired t-test to compare the values measured by manual and EOS methods: there was no statistically significant difference between the two methods. Correlation analysis also showed a statistically significant positive correlation.ConclusionsEOS showed excellent reliability for assessment of the sagittal alignment of the spine and pelvis.

Countries with historically unlimited patient choice of medical provider, such as Korea, have been promoting rational health care pathways. Factors related to the length of doctor-patient relationship (DPR) for enhancing primary care in those countries should be studied. Participants were patients who had visited their family practices on six or more occasions over a period of more than 6 months. Five domains (21 items) of the Korean Primary Care Assessment Tool (first contact, coordination function, comprehensiveness, family/community orientation, and personalized care) and general questions were administered in the waiting rooms. From seven practices, the response rate was 83.7% (495/591). The older the age, the lower the income, the shorter the duration of education, the more the number of diseases the patients had, and in provincial cities rather than in Seoul, the longer length of DPR ( ≥ 4 yr) was shown. The long-term DPR was associated with total primary care quality score (upper [ ≥ 71.4] vs lower [ < 71.4], OR, 1.74; 95% CI, 1.10-2.76), especially with coordination function (OR, 1.01; 95% CI, 1.00-1.02), being adjusted for confounding variables. Strengthening the coordination function may have to be the first consideration in primary care policy in countries like Korea.

Objectives:This study aims to investigate trends of cardiovascular disease (CVD) risk factor profiles over 17 years in percutaneous coronary intervention (PCI) patients at the Mayo Clinic.Methods:We performed a time-trend analysis within the Mayo Clinic PCI Registry from 1994 to 2010. Results were the incidence and prevalence of CVD risk factors as estimate by the Framingham risk score.Results:Between 1994 and 2010, 25 519 patients underwent a PCI. During the time assessed, the mean age at PCI became older, but the gender distribution did not change. A significant trend towards higher body mass index and more prevalent hypercholesterolemia, hypertension, and diabetes was found over time. The prevalence of current smokers remained unchanged. The prevalence of ever-smokers decreased among males, but increased among females. However, overall CVD risk according to the Framingham risk score (FRS) and 10-year CVD risk significantly decreased. The use of most of medications elevated from 1994 to 2010, except for β-blockers and angiotensin converting enzyme inhibitors decreased after 2007 and 2006 in both baseline and discharge, respectively.Conclusions:Most of the major risk factors improved and the FRS and 10-year CVD risk declined in this population of PCI patients. However, obesity, history of hypercholesterolemia, hypertension, diabetes, and medication use increased substantially. Improvements to blood pressure and lipid profile management because of medication use may have influenced the positive trends.
