ABSTRACT

Background@#Throughout the coronavirus disease 2019 (COVID-19) pandemic, not only medical personnel but also paramedics or emergency medical technicians (EMT) have faced multiple physical and psychological challenges while performing their duties. The current study aimed to evaluate the psychological effects of managing patients with COVID-19 on the paramedics and EMT. @*Materials and Methods@#A survey targeting paramedics and EMT in Korea was conducted in December 2020. An official letter requesting participation and with the link to an onlinebased survey was sent to the Public Emergency Medical Services. Only one response was accepted from each participant. @*Results@#A total of 326 paramedics and EMT responded to the survey. Among them, 66.3% (216/326) had experience in managing patients with COVID-19. No differences in the distribution of sex, age, working area, duration of working experience, and underlying comorbidities were observed between those who did (COVID-19 group) and did not (nonCOVID-19 group) experience managing patients with COVID-19. The percentage of participants who showed severe posttraumatic stress disorder (PTSD) symptoms was significantly higher in the COVID group than in the non-COVID group (11.1% vs. 3.6%P = 0.029). The participants in the COVID group had a significantly higher mean Global Assessment of Recent Stress Scale score than those in the non-COVID group (18.7 ± 11.1 vs. 16.1 ± 9.9, P = 0.042). The proportion of paramedics and EMT willing to leave their job if given a chance was higher in the COVID group than the non-COVID group (24.1% vs. 9.1%, P = 0.001). Additionally, paramedics and EMT in the COVID group tended to show concern regarding exposure to COVID-19 infection. @*Conclusion@#The experience of managing patients with COVID-19 resulted in psychological distress among paramedics and EMT in Korea.

ABSTRACT

Background@#This study evaluated the outcomes of medial patellofemoral ligament (MPFL) reconstruction using a gracilis tendon suture technique for patients with patellar instability. Potential factors affecting clinical efficacy were also evaluated. @*Methods@#This study included 22 patients diagnosed with patellar instability, who underwent MPFL reconstruction using a gracilis tendon. Their mean age was 21.5 years (range, 15–48 years), and the mean follow-up period was 26.8 months (range, 12–66 months). Clinical evaluation included the determination of Kujala, Lysholm, and Tegner scores. Radiographic evaluation included changes in congruence angle and arthritic changes in the patellofemoral joint. Additionally, patients were examined for any complications, including recurrent dislocation. Factors affecting clinical efficacy were also evaluated. @*Results@#All clinical scores improved at final follow-up. The mean congruence angle improved from 23.6° before surgery to –6.5° at final follow-up. Two of 15 patients developed osteoarthritic changes in the patellofemoral joint. Dislocation recurred in 2 patients with type C trochlear dysplasia, which showed a statistically significant association with recurrent dislocation when compared to type A and B dysplasia (p = 0.026). Kujala scores were significantly lower among patients with abnormal patellar tilts (p = 0.038), and Lysholm scores were significantly lower among patients with femoral internal rotation deformity (p = 0.024). @*Conclusions@#Satisfactory results were obtained after MPFL reconstruction using a gracilis tendon suture technique for patients with patellar instability. However, dislocation recurred in patients with type C trochlear dysplasia, and clinical efficacy was lower among patients with femoral internal rotation and patellar tilt.

ABSTRACT

Currently, antimicrobial resistance (AMR) is a major threat to global public health. The antimicrobial stewardship program (ASP) has been proposed as an important approach to overcome this crisis. ASP supports the optimal use of antimicrobials, including appropriate dosing decisions, administration duration, and administration routes. In Korea, efforts are being made to overcome AMR using ASPs as a national policy. The current study aimed to develop core elements of ASP that could be introduced in domestic medical facilities. A Delphi survey was conducted twice to select the core elements through expert consensus.The core elements for implementing the ASP included (1) leadership commitment, (2) operating system, (3) action, (4) tracking, (5) reporting, and (6) education. To ensure these core elements are present at medical facilities, multiple departments must collaborate as teams for ASP operations. Establishing a reimbursement system and a workforce for ASPs are prerequisites for implementing ASPs. To ensure that ASP core elements are actively implemented in medical facilities, it is necessary to provide financial support for ASPs in medical facilities, nurture the healthcare workforce in performing ASPs, apply the core elements to healthcare accreditation, and provide incentives to medical facilities by quality evaluation criteria.

ABSTRACT

Purpose@#Under the South Korea’s unique health insurance structure, any new surgical technology must be evaluated first by the government in order to consider whether that particular technology can be applied to patients for further clinical trials as categorized as ‘New Health Technology,’ then potentially covered by the insurance sometime later. The aim of this meta-analysis was to assess the safety and efficacy of transanal total mesorectal excision (TaTME) for rectal cancer, activated by the National Evidence-based Healthcare Collaborating Agency (NECA) TaTME committee. @*Methods@#We systematically searched Ovid-MEDLINE, Ovid-Embase, Cochrane, and Korean databases (from their inception until August 31, 2019) for studies published that compare TaTME with laparoscopic total mesorectal excision (LaTME). End-points included perioperative and pathological outcomes. @*Results@#Sixteen cohort studies (7 for case-matched studies) were identified, comprising 1,923 patients (938 TaTMEs and 985 LaTMEs). Regarding perioperative outcomes, the conversion rate was significantly lower in TaTME (risk ratio, 0.19; 95% confidence interval, 0.11–0.34; P < 0.001); whereas other perioperative outcomes were similar to LaTME. There were no statistically significant differences in pathological results between the 2 procedures. @*Conclusion@#Our meta-analysis showed comparable results in preoperative and pathologic outcomes between TaTME and LaTME, and indicated the benefit of TaTME with low conversion. Extensive evaluations of well-designed, multicenter randomized controlled trials are required to come to unequivocal conclusions, but the results showed that TaTME is a potentially beneficial technique in some specific cases. This meta-analysis suggests that TaTME can be performed for rectal cancer patients as a ‘New Health Technology’ endorsed by NECA in South Korea.

ABSTRACT

Objectives@#This study was conducted to explore recent trends in the prevalence of pediatric elevated blood pressure and hypertension (HTN) in Korea and the United States, applying the new HTN reference values for adolescents. @*Methods@#This study analyzed 17 339 (8755 Korean and 8584 American) adolescents aged 10 to 17 who participated in the Korea National Health and Nutrition Examination Survey and the National Health and Nutrition Examination Survey, respectively, between 2005 and 2016. HTN was defined using percentile-based reference values for non-overweight adolescents from 7 nations, and obesity was defined by body mass index (BMI) based on country-specific growth charts. All analyses were stratified by sex and year-over-year changes were evaluated by calculating the p for trend. @*Results@#Systolic blood pressure showed a statistically meaningful upward trend in Korean boys and girls, while diastolic blood pressure did not show any significant changes. Both systolic and diastolic blood pressure levels declined among United States boys and girls. The prevalence of elevated blood pressure and HTN remained similar in Korean adolescents, but declined in both sexes among United States adolescents. BMI increased in both sexes among Korean adolescents, although the overweight and obesity rates stayed the same. No significant trends were found in any obesity indices among United States adolescents. The prevalence of elevated blood pressure and HTN by obesity level was higher among Korean adolescents than among their United States peers in both sexes, and the gap became higher at more severe levels of obesity. @*Conclusions@#Despite the strong correlation between obesity and HTN, recent trends in the prevalence of HTN and obesity among Korean and United States adolescents were strikingly different. Follow-up studies are necessary to determine why the prevalence of HTN was more than twice as high among Korean adolescents than among their United States counterparts.

ABSTRACT

Background@#Low-dose persistent organic pollutants (POPs), especially organochlorine pesticides (OCPs), have emerged as a new risk factor of many chronic diseases. As serum concentrations of POPs in humans are mainly determined by both their release from adipose tissue to circulation and their elimination from circulation, management of these internal pathways may be important in controlling the serum concentrations of POPs. As habitual physical activity can increase the elimination of POPs from circulation, we evaluated whether chronic physical activity is related to low serum POP concentrations. @*Methods@#A cross-sectional study of 1,850 healthy adults (age ≥20 years) without cardio-metabolic diseases who participated in the U.S. National Health and Nutrition Examination Survey 1999 to 2004 was conducted. Information on moderate or vigorous leisure-time physical activity was obtained based on questionnaires. Serum concentrations of OCPs and polychlorinated biphenyls were investigated as typical POPs. @*Results@#Serum concentrations of OCPs among physically active subjects were significantly lower than those among physically inactive subjects (312.8 ng/g lipid vs. 538.0 ng/g lipid, P<0.001). This difference was maintained after adjustment for potential confounders. When analyses were restricted to physically active subjects, there were small decreases in the serum concentrations of OCPs with increasing duration of physical activity, showing a curvilinear relationship over the whole range of physical activity (Pquadratic <0.001). In analyses stratified by age, sex, body mass index, and smoking status, a strong inverse association was similarly observed among all subgroups. @*Conclusion@#Physical activity may assist in decreasing serum concentrations of lipophilic chemical mixtures such as OCPs.

ABSTRACT

Purpose@#This study evaluated the medial joint stability after high tibial osteotomy (HTO) releasing the superficial medial collateral ligament (sMCL) without cutting and repairing. @*Methods@#Twenty-one patients who performed HTO were enrolled. After an L-shaped incision was made in the pes anserinus, the sMCL was released from the distal portion during surgery. After plate fixation, the sMCL was reattached and the pes anserinus was repaired underneath the plate. Plate removal was performed after 31.1 ± 14.2 months. Before HTO, a valgus force of 40 N was exerted at extension for reference values. Before and after plate removal, a valgus force of 40 N was exerted at extension and at a flexion position of 20°. Medial stability was evaluated by measuring the joint line convergence angle (JLCA). @*Results@#The JLCAs in the extension state before HTO and plate removal were 1.64° ± 1.15° and 1.83° ± 1.36°, respectively; there was no significant difference (p = 0.198). There was also no significant difference in JLCA before HTO and after plate removal (p = 0.835). There was also no significant difference in JLCA before and after plate removal both at a knee extension and flexion position of 20° (p = 0.348 and p = 0.456, respectively). @*Conclusions@#Releasing the sMCL without cutting and repairing the pes anserinus underneath the plate during medial open wedge HTO could facilitate the maintenance of medial joint stability.

ABSTRACT

OBJECTIVES: This study analyzed Korea National Health and Nutrition Examination Survey data from 2007 to 2017 to assess trends in the prevalence, treatment, and control of diabetes in Korean adults ≥30 years of age. METHODS: Prevalent diabetes was defined as a fasting plasma glucose level ≥126 mg/dL, self-reported use of anti-diabetic treatment (insulin or oral anti-diabetic drugs), or diabetes diagnosis by a physician. Target levels were defined as glycosylated hemoglobin <6.5% or <7.0%, blood pressure <130/80 mmHg, and total cholesterol <200 mg/dL. All survey waves were age-standardized to the 2005 Korean census population. RESULTS: Diabetes prevalence increased from 9.6% in 2007–2009 to 10.8% in 2016-2017 (p<0.001). Impaired fasting glucose prevalence significantly increased in both genders and almost every age group. Diabetes awareness and glycemic control did not show an increasing trend; however, the treatment rate and proportion of people diagnosed with diabetes achieving target blood pressure and total cholesterol levels improved from 57.2% to 63.5% (p=0.008), from 41.1% to 53.2% (p<0.001), and from 65.0% to 78.0% (p<0.001), respectively. CONCLUSIONS: From 2007 to 2017, the prevalence of diabetes increased moderately in Korea, whereas the diabetes treatment rate and the proportion of people diagnosed with diabetes achieving target blood pressure and total cholesterol levels improved. However, awareness of diabetes and glycemic control require significant improvements. A national-level action plan is required to raise awareness about diabetes and prediabetes, with the goal of improving glycemic control and minimizing the occurrence of adverse health outcomes.

ABSTRACT

BACKGROUND: Although effective care for type 2 diabetes (T2DM) is well known, considerable inadequate care has been still existed. Variations in achievement of the recommended quality indicators inT2DM care among small areas are not well known in Korea. This study examined the quality of care T2DM care and its geographical variations. METHODS: We used the national health insurance database and national health screening database. Seven quality indicators were used to evaluate continuity of care (medication possession ratio), process of care (hemoglobin A1c test, lipid profile, microalbuminuria test, and eye examination), and intermediate outcome (blood pressure control, and low-density lipoprotein control). Crude and age-standardized proportions were calculated for each 252 districts in Korea. RESULTS: All quality indicators failed to achieve the recommended level. Only about 3% and 15% of the patients underwent eye examination and microalbuminuria test, respectively. Other indicators ranged from 48% to 68%. Wide variation in the quality existed among districts and indicators. Eye examination and microalbuminuria test varied the most showing tenfold (0.9%–9.2%) and fourfold (6.3%–28.9%) variation by districts, respectively. There were 32.4 and 42.7 percentage point gap between the best and the worst districts in hemoglobin A1c test and blood pressure control, respectively. CONCLUSION: Considerable proportion of T2DM patients were not adequately managed and quality of care varied substantially district to district. To improve the quality of diabetes care, it is necessary to identify the poor performance areas and establish a well-coordinated care system tailored to the need of the district.

ABSTRACT

Thermodynamically immiscible poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) were blended and solution-cast by adding the 3% compatibilizer (tributyl citrate, TBC) of the PCL weight. In the PLA/PCL composition range of 99/1–95/5 wt%, mechanical properties of the PLA/PCL films with TBC were always superior to those of the films without TBC. The tensile strength of 42.9 ± 3.5 MPa and the elongation at break of 10.3 ± 2.7% were observed for the 93/7 PLA/PCL films without TBC, indicating that PCL addition is effective for strength and ductility. However, the tensile strength of 54.1 ± 3.4 MPa and the elongation at break of 8.8 ± 1.8% were found for the 95/5 PLA/PCL with TBC, indicating that the effect of co-addition of PCL and TBC on mechanical properties of the films is more pronounced. No cytotoxicity was observed for the PLA/PCL films regardless of TBC addition.

ABSTRACT

PURPOSE@#To determine the role of magnetic resonance cholangiopancreatography (MRCP) in evaluation of choledocholithiasis in patients with suspected cholecystitis.@*MATERIALS AND METHODS@#A total of 78 patients (mean age: 66.06 ± 15.63 years; range: 21–94 years, Male:Female = 31:47) who had experienced symptoms of cholecystitis and who underwent computed tomography (CT), MRCP, and endoscopic retrograde cholangiopancreatography from January 2013 to February 2015 were included in this study. Two reviewers independently interpreted CT and MRCP images to determine the presence or absence of choledocholithiasis and cholelithiasis. Diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, and accuracy) was compared between CT and MRCP. Interobserver agreement was also evaluated.@*RESULTS@#Forty-three patients underwent cholecystectomy. The accuracy of CT and MRCP for detection of gallbladder stones showed no significant difference. The sensitivity and accuracy of MRCP for detection of extrahepatic duct stones were superior to those of CT for both reviewers (reviewer 1: MRCP: sensitivity, 73.3%; accuracy, 76.9%; CT: sensitivity, 50%, accuracy 59%; p = 0.01; reviewer 2: MRCP: sensitivity, 75%; accuracy, 73.1%; CT: sensitivity, 50%; accuracy, 56.4%; p = 0.018). The interobserver agreement was consistent for both CT (k-value: 0.738) and MRCP (k-value: 0.701).@*CONCLUSION@#MRCP showed superior diagnostic performance for the detection of choledocholithiasis with reliable interobserver agreement. Considering the lack of radiation and contrast enhancement, MRCP would be an appropriate first-line modality in evaluation of common bile duct stones in patients with suspected cholecystitis.

ABSTRACT

PURPOSE: This study evaluated the efficacy of a smartphone application in the measurement of rotation angles in porcine knees. MATERIALS AND METHODS: Two K-wires were fixated to the femoral condyle and anterior tibial crest of 10 porcine legs. The angle created between the K-wires with an external rotation force applied was measured on a photograph and defined as the true angle. The same force was applied to the legs placed on a splint with a smartphone attached to the plantar side. The angle presented on a smartphone application was determined as the measured angle. The differences between the true and measured angles in 30° and 90° knee flexion and differences in measured angles depending on the status of the popliteus tendon were compared. RESULTS: In the intact knees, the mean true angles in 30° and 90° flexion were 20.5°±1.4° and 19.1°±1.3°, respectively, and the mean measured angles in 30° and 90° flexion were 21.1°±0.9° and 18.6°±1.6°, respectively. When the popliteus tendon was cut, the mean true angles in 30° and 90° flexion were 31.4°±1.1° and 38.5°±2.5°, respectively, and the mean measured angles in 30° and 90° flexion were 31.8°±1.2° and 39.2°±2.8°, respectively. The differences between the true and measured angles were not significant. The measured angle increased by more than 10° after cutting of the popliteus tendon in both 30° and 90° flexion. CONCLUSIONS: Using a smartphone application could be a good method of measuring knee rotation.

ABSTRACT

The lumbar sympathetic ganglion block (LSGB) is widely used for diagnosing and treating sympathetically maintained pain disorders. The LSGB has been conventionally carried out under fluoroscopy or computed tomography guidance. However, as ultrasound technology improved, ultrasound-guided interventions have been expanding their territory to deeper structures. Ultrasound guidance provides many benefits including protecting vascular injection, shortening procedure time in some cases, and reducing the emission of radiation. In this report, we describe a successful case of a US-guided LSGB without major complications. We expect that US-guided LSGBs can be implemented and furnished in the daily outpatient clinical setting by highly trained pain physicians.

ABSTRACT

BACKGROUND: The high cost of intrathecal morphine pump (ITMP) implantation may be the main obstacle to its use. Since July 2014, the Korean national health insurance (NHI) program began paying 50% of the ITMP implantation cost in select refractory chronic pain patients. The aims of this study were to investigate the financial break-even point and patients' satisfaction in patients with ITMP treatment after the initiation of the NHI reimbursement. METHODS: We collected data retrospectively or via direct phone calls to patients who underwent ITMP implantation at a single university-based tertiary hospital between July 2014 and May 2016. Pain severity, changes in the morphine equivalent daily dosage (MEDD), any adverse events, and patients' satisfaction were determined. We calculated the financial break-even point of ITMP implantation via investigating the patient's actual medical costs and insurance information. RESULTS: During the studied period, 23 patients received ITMP implantation, and 20 patients were included in our study. Scores on an 11-point numeric rating scale (NRS) for pain were significantly reduced compared to the baseline value (P < 0.001). The MEDD before ITMP implantation was 0.59 [IQR: 0.55–0.82]. The total MEDD increased steadily to 0.77 [IQR: 0.53–1.08] at 1 year, which was 126% of the baseline (P < 0.001). More than a half (60%) responded that the ITMP therapy was somewhat satisfying. The financial break-even point was 28 months for ITMP treatment after the NHI reimbursement policy. CONCLUSIONS: ITMP provided effective chronic pain management with improved satisfaction and reasonable financial break-even point of 28 months with 50% financial coverage by NHI program.

ABSTRACT

PURPOSE: Epidemiological studies have demonstrated an association between excessive salt intake and gastric cancer risk, and this potential risk increases the need for adequate gastric cancer screening in individuals with high salt intake. However, the association between salt intake and gastric cancer screening in the general population has rarely been investigated. We explored the association between salt preference and participation in gastric cancer screening among a nationally representative Korean population. MATERIALS AND METHODS: The study population was derived from the Korean National Cancer Screening Survey (KNCSS) 2006-2007, an annual nationwide interview survey investigating cancer screening rates. Of 4,055 individuals who participated in the KNCSS 2006-2007, 3,336 individuals aged over 40 years were included in our analysis. The odds ratio (OR) and 95% confidence interval (CI) were estimated using polytomous logistic regression. RESULTS: Individuals with higher salt preference were less likely to participate in regular gastric cancer screening. After adjusting for age, sex, monthly household income, education, family history of cancer, and self-rated health status, ORs for undergoing regular gastric cancer screening were 1.00, 0.82 (95% CI, 0.61 to 1.12), 0.74 (95% CI, 0.54 to 1.00), 0.77 (95% CI, 0.56 to 1.05), and 0.38 (95% CI, 0.16 to 0.92) according to the level of salt preference (p for trend=0.048). CONCLUSION: Individuals with higher salt preference showed suboptimal gastric cancer screening adherence compared to those with a lower salt preference. These findings highlight the need for better delivery of educational messages to change risk perceptions regarding gastric cancer screening practice.

ABSTRACT

PURPOSE: Early diagnosis and an improved survival rate have emerged as important issues for cancer survivors returning to work during the prime of their working life. This study investigated the attitudes of the general public towards cancer survivors returning to work in Korea and attempted to identify the factors influencing this negative attitude. MATERIALS AND METHODS: A general public perception survey regarding cancer survivors returning to work, targeting 2,000 individuals between 40-70 years of age, was conducted as face-to-face home visit. RESULTS: The public expressed a negative attitude towards cancer survivors returning to work, in terms of both perception and acceptance. Negative perception was higher among those in metropolitan areas compared with urban/rural areas (odds ratio [OR], 1.71), with monthly incomes $4,000 (OR, 1.54), and with patient care experience compared with those without (OR, 1.41). Negative acceptance was higher among those with monthly incomes $4,000 (OR, 1.71) and those with patient care experience compared with those without (OR, 1.54). The common factors between acceptance and perception that influenced negative attitude included area of residence, patient care experience, and monthly income. CONCLUSION: This study identified negative attitudes towards cancer survivors returning to work in South Korea and the factors influencing the reintegration of cancer survivors into society. It is necessary to promote community awareness and intervention activities to enable access to community, social, and individual units for the social reintegration of cancer survivors.
