BACKGROUND: Dating violence refers to violence occurring between people in an intimate relationship. Forms of dating violence are often categorized into physical, psychological, and sexual violence, and most existing literature has followed this frame. However, few studies have focused on the phenomenon of living under the perpetrator's coercive control in victims of dating violence, although those experiences are known to be signs of severe forms of violence later on. PURPOSE: The purpose of this study was to explore the experiences of being coercively controlled in female victims who had experienced dating violence. METHODS: For this study, in-depth interviews were conducted with a total of 14 female victims, and all interviews were audio-recorded and transcribed. The data were analyzed using the phenomenological analysis method suggested by Colaizzi. RESULTS: Three themes were derived in chronological order: idealizing the relationship (period of potential control), facing severer tyranny (period of coercive control), and escaping from the unending trap (period of post-control). The results showed that the victims experienced perpetrators' control with specific patterns. The perpetrators' controlling behaviors were invisible, literally benevolent, at the beginning; however, severe forms of violence seemed to appear as their relationship deepened and the perpetrators failed to control the victims. CONCLUSION: Findings from this study presented vivid experiences of female victims who needed help and care. Hopefully, the results can benefit in terms of developing evidence-based prevention strategies for victims as well as assessing the risks of severe forms of dating violence, such as physical attack or murder.

Despite hearing loss being a prevalent chronic condition, estimated to nearly 20% of the global population by the World Health Organization, the specific association with individual lifestyle factors, particularly alcohol consumption, remains unclear. In South Korea, approximately 80% of the population engages in alcohol consumption, with a notably high prevalence among males, indicating a high-risk drinking pattern. Therefore, this study aimed to assess the correlation between alcohol consumption and hearing loss in male workers, as well as to analyze additional variables such as alcohol flushing reaction, with the intention of improving worker health.

BACKGROUND: Methotrexate (MTX) is an antifolate antagonist that is widely used for treating various malignancies and non-malignant diseases. MTX levels should be monitored when used in high concentration to determine when to start leucovorin rescue. In this study, we evaluated the analytical performance of the EMIT Methotrexate Assay on a 200FR NEO Chemistry Analyzer (Toshiba Medical System Co., Japan) and compared it with Viva-E Drug Testing System (Siemens Healthcare, Germany). METHODS: According to the Clinical Laboratory and Standards Institute (CLSI) Evaluation Protocol (EP) 5-A2, three concentrations of the Liquichek Therapeutic Drug Monitoring Control (Bio-Rad Laboratories, USA) were analyzed twice a day for 20 days to monitor assay precision. The 200FR NEO and Viva-E instruments were compared using 40 patients' sera, according to CLSI EP9-A2. The linearity and carry-over rate were also evaluated. RESULTS: Between-run CVs for low-, medium-, and high-level controls were 4.9%, 0.9%, and 2.0%, respectively, whereas between-day CVs for low-, medium-, and high-level controls were 8.1%, 1.3%, and 3.5%, respectively. In the linearity test, the coefficient of determination (R2) was 0.98 (0.06-1.92 micromol/L). In the comparison study, R2 was 0.955, showing good correlation between the 200FR NEO and Viva-E instruments. The carry-over rate was 0.9%. CONCLUSIONS: The EMIT assay showed good precision, linearity, and carry-over rate on the Toshiba 200FR. An excellent correlation was observed when comparing results obtained using the Toshiba and Viva-E instruments. In conclusion, the Syva EMIT MTX assay can be readily used for MTX monitoring on the Toshiba 200FR NEO.

BACKGROUND: Diagnosing albuminuria by measuring the urinary albumin-creatinine ratios (UACR) is important for the early detection of kidney diseases in patients with diabetes or hypertension. Currently, a few point-of-care testing (POCT) systems exist for estimating the UACR. Here, we evaluated the performance characteristics of two semi-quantitative UACR POCT assays. METHODS: Albumin and creatinine levels were quantified for 219 randomly acquired urine samples with the Toshiba TBA-200FR NEO analyzer, and the UACR were calculated. The results were compared to UACR measured using the CLINITEK Microalbumin 2 Strip (Siemens, USA) and URiSCAN 2 ACR Strip (YD diagnostics, Korea) POCT assays. RESULTS: Semi-quantitative results from the CLINITEK and URiSCAN UACR assays showed that the sensitivity and specificity of each test were, respectively, 96.7% and 62.7%, and 45.9% and 84.8%. Positive and negative predictive values of the CLINITEK and URiSCAN tests were, respectively, 50.0% and 98.0%, and 53.8% and 80.2%. The rate of agreement between URiSCAN test and CLINITEK test was 91.1% in the normal UACR range (<30 mg/g), but it was as low as 36.4% in the abnormal UACR range (> or =30 mg/g). CONCLUSIONS: The URiSCAN test showed higher specificity than did the CLINITEK test owing to the lower false positive results. However, the high rate of false negatives for the URiSCAN test significantly lowered its sensitivity and negative predictive values. Therefore, the sensitivity of the URiSCAN device in detecting urine albumin needs to be improved before its adoption as a reliable rule-out testing system.

BACKGROUND: Hemoglobin (Hb)-A1c is routinely used for the management of diabetes. In 2010, HbA1c was included into the diagnostic criteria for diabetes by the American Diabetes Association. A newly developed HbA1c analyzer, ARKRAY ADAMS HA-8180 (ARKRAY KDK, Japan) was introduced. In this study, we evaluated the analytical performance of ARKRAY ADAMS HA-8180 HbA1c analyzer and compared it with the previously used Variant II Turbo (Bio-Rad Laboratories, USA), which is a National Glycohemoglobin Standardization Program (NGSP) certified analyzer. METHODS: According to Clinical Laboratory and Standards Institute (CLSI) evaluation protocol (EP) 5-A, Lyphochek Diabetes Controls (Bio-Rad Laboratories, USA) are used for precision. Two (low and high) levels of quality control materials were analyzed twice a day for 20 days, after which the mean, total standard deviation (SD) and total coefficient of variation (CV), including the between-run CV and between-day CV were calculated. ARKRAY ADAMS HA-8180 HbA1c analyzer and Variant II Turbo were compared with 150 samples according to CLSI EP9-A2. In addition, the linearity and carry over rate were evaluated. RESULTS: Between-run CVs for low and high level quality control materials were 0.0% and 0.3%, respectively, whereas between-day CVs for low and high level quality control materials were 0.3% and 0.2%, respectively. In the linearity test, the coefficient of determination (R2) was 0.99 (range, 3.1-19.3%). Thus, a good correlation was observed between ARKRAY ADAMS HA-8180 HbA1c analyzer and Variant II Turbo (R2=0.994). The carry over rate was 0.0%. CONCLUSIONS: The ARKRAY ADAMS HA-8180 HbA1c analyzer showed excellent precision, linearity, and carryover rate. It also showed excellent correlation with the NGSP certified Variant II Turbo. In conclusion, the ARKRAY ADAMS HA-8180 HbA1c analyzer is a reliable high-performance liquid chromatography (HPLC) analyzer for HbA1c analysis and could be very useful for the diagnosis, treatment, monitoring, and risk assessment of diabetes.
