Roche Diagnostics has recently released the Elecsys FT4 III, Roche's third-generation reagent for free thyroxine. We aim to evaluate the analytical performance of the Elecsys FT4 III.

The precision and linearity of the Elecsys FT4 III assay were evaluated according to Clinical and Laboratory Standards Institute procedures. The results of the third-generation assay were compared with that of Roche's second-generation assay (Elecsys FT II) on a Roche cobas e801 modular analyzer.

The coefficient of variation of within-laboratory variation was less than 2.6% for the control materials and patient samples. The linearity was confirmed over a range of 0.41 to 7.52 ng/dL. The mean difference between the second- and third-generation reagents was 0.0026 ng/dL (95% confidence interval, -0.0172 to +0.0224 ng/dL).

The analytical performance of the Elecsys FT4 III assay for free thyroxine is clinically acceptable.

Due to the insidious onset of multiple myeloma (MM), missed diagnosis and misdiagnosis have a serious impact on the health of MM patients. Simple, rapid, and valid laboratory screening is critical for MM clinical diagnosis.

We used routine laboratory tests to establish a simple, inexpensive, and non-invasive diagnostic model for MM based on logistic regression. In the retrospective analysis, a total of 273 newly diagnosed MM inpatients and 288 non-MM participants, from January 2016 to December 2018 in Beijing Chaoyang hospital, Capital Medical University, were divided into training set and validation set. Age, gender, and the related routine laboratory tests for MM, including albumin (ALB), globulin (GLB), lactate dehydrogenase (LDH), creatinine (Cr), calcium (Ca2+), hemoglobin (Hb) and platelet (PLT), were analyzed by multivariate logistic regression to develop a diagnostic model.

A diagnostic model was calculated using the formula MM index=-((-18×gender-3×ALB-Hb)/10), based on the logistic regression.iagnostic model of MM index may also act as a predictor of the severity of MM without therapy.
In February 2020, a coronavirus disease 2019 (COVID-19) outbreak was reported in fitness centers in Cheonan, Korea.

From February 24 to March 13, an epidemiological investigation was conducted on the fitness center outbreak. All those who were screened were tested for severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) using real-time reverse transcriptase polymerase chain reaction. Contacts were traced and self-isolated for 14 days. We determined the epidemiological characteristics of confirmed cases of SARS-CoV-2 infection, and estimated the time-dependent reproduction number to assess the transmission dynamics of the infection.

A total of 116 cases were confirmed, and 1,687 contacts were traced. The source cases were 8 Zumba instructors who led aerobics classes in 10 fitness centers, and had the largest average number of contacts. A total of 57 Zumba class participants, 37 of their family members, and 14 other contacts were confirmed as cases. The attack rate was 7.3%. The contacts at Zumba classes and homes had a higher attack rate than other contacts. The mean serial interval (± standard deviation) were estimated to be 5.2 (± 3.8) days. The time-dependent reproduction number was estimated to be 6.1 at the beginning of the outbreak, but it dropped to less than 1, 2 days after the epidemiological investigation was launched.

The results suggest that the COVID-19 outbreak was effectively contained with rigorous contact tracing, isolating, and testing in combination with social distancing without a lock-down.

This study was performed to compare the viral load and kinetics of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in saliva with those in standard nasopharyngeal/oropharyngeal (NP/OP) swabs.

Fifteen patients with SARS-CoV-2 infection from four hospitals were prospectively enrolled and matched samples of nasopharyngeal/oropharyngeal swabs and saliva were collected at Day 1 of admission and every other day till consequently negative for two times. Real-time reverse transcription polymerase chain reaction (rRT-PCR) was performed to detect the envelope (E) and RNA-dependent RNA polymerase (RdRP) genes.

The cycle threshold values of saliva were comparable to those of NP/OP swabs overall (
= 0.720, Mann-Whitney U test). However, the overall sensitivity of rRT-PCR using saliva was 64% (34/53), which is lower than the 77% (41/53) using NP/OP swabs. The sensitivity of rRT-PCR using saliva was especially lower in early stage of symptom onset (1-5 days; 8/15; 53%) and in patients who did not have sputum (12/22; 55%).

Saliva sample itself is not appropriate for initial diagnosis of coronavirus disease 2019 (COVID-19) to replace NP/OP swabs, especially for the person who does not produce sputum. COVID-19 cannot be excluded when the test using saliva is negative, and it is necessary to retest using NP/OP swabs.

The study participants were 180 students between the ages of 9 and 18 years. Path analysis was performed to measure the relationships among ACEs, depressive symptoms and problematic internet use. ACEs significantly affected depressive symptoms (standardized regression weight, 0.36; P less then 0.01), and depressive symptoms also affected problematic internet use (standardized regression weight, 0.40; P less then 0.01). We found that depressive symptoms had a significant mediating effect on the relationship between problematic internet use and ACEs. The management of depressive symptoms would be important to prevent problematic internet use in children and adolescents with ACEs.
Recently, new concepts about obesity and normal weight subtypes with metabolic conditions are rising and ketone bodies are emerging as a significant indicator of metabolic health. This study aimed to find a relationship between ketonuria and those subtypes.

The data of 19,036 subjects were analyzed in this cross-sectional study (2013-2017 Korea National Health and Nutrition Examination Survey, KNHANES). Based on body mass index and adult treatment panel III with modification of waist circumference, individuals were categorized into 4 groups metabolically healthy normal weight (MHNW), metabolically healthy obese (MHO), metabolically unhealthy normal weight (MUNW), and metabolically unhealthy obese (MUO). Individuals were divided into 2 groups, positive and negative ketonuria groups, and the metabolic parameters were compared.

The metabolic indicators of the positive ketonuria group showed better results than those of the negative ketonuria group and the MHNW group showed the highest proportion of positive ketonuria. The MHNW group showed higher urinary ketones than the MUO group (odds ratio [OR], 0.391; 95% confidence interval [CI], 0.254-0.601) in men. In women, OR of having ketonuria was 0.698 (95% CI, 0.486-1.002) in the MHO group and 0.467 (95% CI, 0.226-0.966) in the MUNW group compared to the MHNW group, respectively.

Compared to the MHNW group, the MUO group showed lower presence of ketonuria in men, and tendency to have less ketonuria in women.

In Korea, the Korean Community-based Noncommunicable Disease Prevention and Control Program (KCNPC) was implemented in 2012 for the management of patients with chronic diseases. Nineteen primary care clinics, public health centers, and education and consulting centers (ECCs) participated in the implementation of this program. This study assessed the effectiveness of this chronic disease control model by comparing mortality rate and the incidence of complications between patients participating in the KCNPC program and a control group.

Using data from the National Health Insurance Service and data from hypertension and diabetes patients registered with 19 ECCs between January 1, 2010 and December 31, 2012, hypertension and diabetes patients who had been treated at a clinic were selected. The final analysis included 252,900 patients, with the intervention group and control group having 126,450 patients each. Survival for the two groups was analyzed using the Kaplan-Meier method. Complications were analyzed uorea was found to be effective for hypertension and diabetes patients. Therefore, the KCNPC will be necessary to strengthen the capabilities of local communities, primary medical institutions, and individuals for prevention and control of chronic disease. Expanding the efficient prevention and control policies of the KCNPC to a nationwide scale may be effective as has been demonstrated through limited implementation in some regions.
To elucidate the achievement rates of imaging remission and to examine the characteristics associated with imaging remission status among patients with rheumatoid arthritis (RA) who have attained clinical remission.

Ninety-seven patients with RA patients who had attained clinical remission, defined by DAS28-ESR < 2.6 were enrolled. Power Doppler ultrasonography (PDUS) was performed on 16 joints and 2 tendons, including the first to third metacarpophalangeal, second and third proximal interphalangeal, radiocarpal (RC), second and third metatarsophalangeal joints, and extensor carpi ulnaris tendons. They were graded based on a dichotomous assessment. The clinical and laboratory data of patients who had attained imaging remission were compared to those of patients who had attained only clinical remission.

The imaging remission rate was 51.5% in patients who had attained clinical remission. Forty-seven patients (48.5%) were PDUS positive. Power Doppler was detected most frequently in the right RC joint (who had attained imaging remission had lower EGA scores and higher RF levels than patients who had attained only clinical remission.
The aim of this study was to present and analyze, for the first time, the results of a government-supported nationwide newborn hearing screening (NHS) pilot project in the 17 major cities and provinces of Korea.

We analyzed a nationwide NHS database of 344,955 newborns in the pilot project from 2014 to 2018. The government supported the cost of one NHS and one diagnostic auditory brainstem response (ABR) test. Hearing loss (HL) was defined as ≥ 40 dB nHL on either side of the ABR threshold test.

Most NHS tests were performed in the maternity clinics (91.5%). In regions with lack of maternity clinics, the screening rate of local clinics was high (Jeju 31.1% and Sejong 12.9%). In most regions, automated ABR was mainly used for screening test (89.7%), but Gangwon (32.7%), Jeju (31.0%), and Jeonbuk (29.6%) performed more NHS tests using (automated) otoacoustic emissions than other regions. The mean referral rate was 1.5%, but the overall diagnostic ABR rate was low at 18.5%. The referral rates of Busan (0.6%) and Gyeongnam (0.
