RESUMO
Objective@#To compare the efficacy of home-based cardiac rehabilitation (HBCR) and center-based cardiac rehabilitation (CBCR) in cardiovascular risk factor management. @*Methods@#We performed retrospective review of the electronic medical records of 72 patients who were hospitalized for acute coronary syndrome and participated in a cardiac rehabilitation (CR) program for the first time. The participants were stratified into the HBCR group, receiving educational programs and performing self-exercise at home, and the CBCR group, participating in electrocardiogram monitoring monitoring exercise training in hospital settings. The results of the Lifestyle Questionnaire survey were investigated at baseline, 3 months, and 6 months. @*Results@#Both groups showed significant improvements in serum low-density lipoprotein levels, frequency of alcohol consumption, eating habits and psychological status. Moderate-intensity exercise duration and the maximal metabolic equivalents values improved significantly in both groups but slightly more in the CBCR group. However, the number of current smokers increased in both groups, and no significant changes were found in body mass index, serum glycated hemoglobin levels, serum high-density lipoprotein levels, or high-intensity exercise duration. @*Conclusion@#Regardless of the CR program type, a patient’s lifestyle can be modified. Therefore, patients should continue participating in any type of CR program.
RESUMO
Objective@#To evaluate the following null hypothesis: the skeletal and dentoalveolar expansion patterns in the coronal and axial planes are not different with two different types of microimplant-assisted rapid palatal expansion (MARPE) systems. @*Methods@#Pretreatment (T0) and post-MARPE (T1) cone-beam computed tomography (CBCT) images of 32 patients (14 males and 18 females; mean age, 19.37) were analyzed. We compared two different MARPE systems. One MARPE system included the maxillary first premolars, maxillary first molars, and four microimplants as anchors (U46 type, n = 16), while the other included only the maxillary first molars and microimplants as anchors (U6 type, n = 16). @*Results@#In the molar region of the U6 and U46 groups, the transverse expansion at the midnasal, basal, alveolar, and dental levels was 2.64, 3.52, 4.46, and 6.32 mm and 2.17, 2.56, 2.73, and 5.71 mm, respectively. A significant difference was observed in the posterior alveolar-level expansion (p = 0.036) and posterior basal-bone-level expansion (p = 0.043) between the groups, with greater posterior skeletal and alveolar expansion in the U6 group. @*Conclusions@#Compared with the U46 group, the U6 group showed greater posterior expansion at the alveolar and basal-bone levels, with an almost parallel split. Both groups showed a pyramidal expansion pattern in the coronal view.
RESUMO
Transarterial chemoembolization (TACE) was introduced in 1977 with the administration of chemotherapeutic agent to gelatin sponge particles through the hepatic artery in patients with hepatocellular carcinoma (HCC) and was established as conventional TACE using Lipiodol in the 1980s. In the 2000s, drug-eluting beads were developed and applied clinically. Currently, TACE is a commonly used non-surgical treatment modality for patients with HCC who are unsuitable for curative treatment. Considering the vital role of TACE in the management of HCC, it is crucial to organize current knowledge and expert opinions regarding patient preparation, procedural techniques, and post-treatment care in TACE, which can enhance therapeutic efficacy and safety. A group of 12 experts in the fields of interventional radiology and hepatology, convened by the Research Committee of the Korean Liver Cancer Association (KLCA), has developed expert consensus-based practical recommendations in TACE. These recommendations have been endorsed by the Korean Society of Interventional Radiology and provide useful information and direction in performing TACE procedure as well as pre- and post- procedural patient care.
RESUMO
Background@#/Aim: Despite the increasing proportion of elderly patients with hepatocellular carcinoma (HCC) over time, treatment efficacy in this population is not well established. @*Methods@#Data collected from the Korean Primary Liver Cancer Registry, a representative cohort of patients newly diagnosed with HCC in Korea between 2008 and 2017, were analyzed. Overall survival (OS) according to tumor stage and treatment modality was compared between elderly and non-elderly patients with HCC. @*Results@#Among 15,186 study patients, 5,829 (38.4%) were elderly. A larger proportion of elderly patients did not receive any treatment for HCC than non-elderly patients (25.2% vs. 16.7%). However, OS was significantly better in elderly patients who received treatment compared to those who did not (median, 38.6 vs. 22.3 months; P0.05). After IPTW, in intermediate-stage HCC, surgery (median, 66.0 vs. 90.3 months) and transarterial therapy (median, 36.5 vs. 37.2 months), and in advanced-stage HCC, transarterial (median, 25.3 vs. 26.3 months) and systemic therapy (median, 25.3 vs. 26.3 months) yielded comparable OS between the elderly and non-elderly HCC patients (all P>0.05). @*Conclusions@#Personalized treatments tailored to individual patients can improve the prognosis of elderly patients with HCC to a level comparable to that of non-elderly patients.

RESUMO
Background/Aims@#A relationship between fatty liver and lung function impairment has been identified, and both are independently associated with metabolic dysfunction. However, the temporal relationship between changes in fatty liver status and lung function and their genome-wide association remain unclear. @*Methods@#This longitudinal cohort consisted of subjects who received serial health check-ups, including liver ultrasonography and spirometry, for ≥3 years between 2003 and 2015. Lung func-tion decline rates were classified as “slow” and “accelerated” and compared among four different sonographic changes in steatosis status: “normal,” “improved,” “worsened,” and “persistent.” A genome-wide association study was conducted between the two groups: normal/improved steatosis with a slow decline in lung function versus worsened/persistent steatosis with an accelerated decline in lung function. @*Results@#Among 6,149 individuals, the annual rates of decline in forced vital capacity (FVC) and forced expiratory volume measured in the first second of exhalation (FEV 1 ) were higher in the worsened/persistent steatosis group than in the normal/improved steatosis group. In multivariable analysis, persistent or worsened status of fatty liver was significantly associated with accelerated declines in FVC (persistent status, odds ratio [OR]=1.22, 95% confidence interval [CI]=1.04–1.44; worsened status, OR=1.30, 95% CI=1.12–1.50), while improved status of fatty liver was significantly associated with slow declines in FEV 1 (OR=0.77, 95% CI=0.64–0.92). The PNPLA3 risk gene was most strongly associated with steatosis status change and accelerated declines in FVC (rs12483959, p=2.61×10 -7 ) and FEV 1(rs2294433, p=3.69×10 -8 ). @*Conclusions@#Regression of fatty liver is related to lung function decline. Continuing efforts to improve fatty liver may preserve lung function, especially for subjects with a high genetic risk.
RESUMO
The purpose of this study was to investigate the current status of interprofessional education (IPE) and the efforts required to promote, popularize, and implement it in Korea. The IPE status of 40 medical colleges was investigated using a survey with questions regarding the details of IPE, the future plans and necessary support required, and the reasons for not implementing IPE. Thirty-two medical colleges responded, of which 10 are implementing or have implemented IPE. Most of these colleges started IPE in 2018, and the duration of IPE was less than 9 hours. All medical colleges held classes with nursing students. As for the type of IPE, there were independent courses for IPE, one-time special lectures, or partial sessions in one course. Lectures, discussions and presentations, role playing, and high-fidelity simulations were mainly used as educational methods. The support and interest of the dean was the most important facilitating factor. No medical colleges were currently preparing to implement IPE, four colleges had planned IPE but failed to implement it, and 16 had no plans for IPE at all. All medical colleges cited scheduling or cooperation with other majors as the most significant barrier. All the colleges listed their requirements for educational materials, cases, guidelines, and teaching and learning methods for IPE from external institutions. To activate IPE, it is necessary to create an appropriate atmosphere and conditions for developing IPE competencies and a model suitable for the domestic situation. External medical education support organizations should distribute IPE development guidelines and educational materials, form a network between medical colleges with IPE experience, and make efforts to promote the importance of IPE.
RESUMO
Background/Aims@#Accumulating evidence suggests a link between non-alcoholic fatty liver disease (NAFLD) and brain health. However, population-based evidence on the association between NAFLD and dementia remains unclear. This study was conducted to determine the association between NAFLD and incident dementia. @*Methods@#The study population included 608,994 adults aged ≥60 years who underwent health examinations between 2009 and 2010. Data were collected from the Korean National Health Insurance Service database. NAFLD was assessed using the fatty liver index (FLI). A Cox proportional hazards regression model was used to determine the association between NAFLD and dementia. @*Results@#During the 6,495,352 person-years of follow-up, 48,538 participants (8.0%) developed incident dementia. The participants were classified into low (FLI <30), intermediate (FLI ≥30 and <60), and high (FLI ≥60) groups. In the overall study population, the FLI groups were associated with a risk of dementia (P for trend <0.001). After propensity score matching, a low FLI was associated with a reduced risk of dementia (adjusted hazard ration [aHR], 0.96; 95% confidence interval [CI], 0.93–0.98; P=0.002), whereas a high FLI (NAFLD) was associated with an increased risk of dementia (aHR, 1.05; 95% CI, 1.02–1.08; P=0.001). A higher risk of dementia in the high FLI group than in the intermediate FLI group was attributed to Alzheimer’s disease (aHR, 1.04; 95% CI, 1.01–1.07; P=0.004) rather than vascular dementia (aHR, 0.94; 95% CI, 0.75–1.18; P=0.602). @*Conclusions@#NAFLD was associated with an increased risk of dementia, which was attributed to an increased risk of Alzheimer’s disease.
RESUMO
Background@#This study aimed to investigate the effect of selecting commercially available blending teas and applying them to bovine teeth on color change over time. @*Methods@#After selecting healthy bovine teeth, using a cutting-disc, 105 specimens with a dimension of 5×5×3 mm were prepared, and 15 specimens were distributed to each group. Black tea was used as a positive control, water was used as a negative control, and blended tea of five types was used as an experimental group. First, pH and buffering capacity were measured with a pH meter, and tooth color was determined using a spectrophotometer before immersion in the blending tea solution and 1, 5, 7, 14, and 21 days after immersion. Thereafter, the shape change of the enamel surface was observed using a scanning electron microscope, and SPSS ver.26 was used to analyze the color change. @*Results@#The average pH of the five blending teas in the experimental group was 3.78, and the pH of group 3 (strawberry rhubarb) was the lowest at 3.22. The pH levels of black tea and water were 5.19 and 7.30, respectively. The buffering capacity was the highest in group 3 at both pH levels of 5.5 and 7.0. The L*a*b* color change according to immersion time was the largest in group 4 (rooibos yellow flower), and the amount of color change was large in black tea and group 4. As a result of observing the enamel surface of bovine teeth, changes in the surface shape were noted in all groups immersed in the experimental solution for 21 days, except for water. @*Conclusion@#There was a significant difference between the experimental groups in terms of color change according to the immersion time, and color and enamel surface changes were observed in black tea and all experimental groups, except for water.
RESUMO
Purpose@#This study aimed to assess the feasibility of operational definitions of cancer patients in conducting cancer-related studies using the claims data from the National Health Insurance Service (NHIS). @*Materials and Methods@#Cancer incidence data were obtained from the Korean Central Cancer Registry, the NHIS primary diagnosis, and from the rare and intractable disease (RID) registration program. @*Results@#The operational definition with higher sensitivity for cancer patient verification was different by cancer type. Using primary diagnosis, the lowest sensitivity was found in colorectal cancer (91.5%; 95% confidence interval [CI], 91.7 to 92.0) and the highest sensitivity was found in breast cancer (97.9%; 95% CI, 97.8 to 98.0). With RID, sensitivity was the lowest in liver cancer (91.9%; 95% CI, 91.7 to 92.0) and highest in breast cancer (98.1%; 95% CI, 98.0 to 98.2). In terms of the difference in the date of diagnosis in the cancer registration data, > 80% of the patients showed a < 31-day difference from the RID definition. @*Conclusion@#Based on the NHIS data, the operational definition of cancer incidence is more accurate when using the RID registration program claims compared to using the primary diagnosis despite the relatively lower concordance by cancer type requires additional definitions such as treatment.
RESUMO
The genus Mitrula (Mitrulaceae, Helotiales), as also known as swamp beacons, inhabits submerged, decaying vegetation in standing or decaying needles, twigs, leaves, and shallow water. They play an important role in carbon cycling in some freshwater ecosystems. In the herbarium of the Korea National Arboretum (KH), seven Mitrula specimens were collected during mushroom forays in the period from 2019 to 2021. The Korean collections were found to be macromorphologically closely related to M. paludosa and M. elegans, but micromorphologically they could be distinguished by characteristics of slightly narrower asci and aseptate ascospores. Our molecular phylogenetic analyses of the internal transcribed spacer (ITS) and 28S rDNA regions also revealed that our specimens were related to M. paludosa and M. elegans, but formed a distinct clade. Based on these results, we reported our specimens as new to science and discussed the phylogeny and diversity ofMitrula species.
RESUMO
Background@#Plastic waste generates pollutants in the process of incineration or landfilling, and accumulates in water or marine organisms, causing adverse effects on the environment and the human body. Recently, various eco-friendly oral hygiene products (Eco-OHPs) such as bamboo toothbrushes and biodegradable plastic toothbrushes have been developed. Therefore, this study aimed to investigate the current level of awareness and purchasing status of eco-OHPs among adults who are interested in eco-friendly products. @*Methods@#This study included adults aged ＞19 years who regularly visited eco-friendly shops and online sites; the online survey links were distributed during their visits to eco-friendly Internet cafés and companies. Of the 22 questions, seven assessed the participants’ general characteristics, three assessed the general oral hygiene care products used, six assessed the level of awareness of Eco-OHPs, and six assessed the purchasing status of Eco-OHPs. Frequency analysis, chi-square test, and regression analysis were performed using SPSS software. @*Results@#Among the respondents, 108 (51.4%) were aware of Eco-OHPs, and 79 (37.6%) had experience purchasing Eco-OHPs. The most common reason for not purchasing was the lack of information about related brands or products (74, 56.5%). The most common platform used in obtaining information was the Internet (general: 31.5%, eco-friendly: 46.3%), such as Social Network Service, Internet cafes, and blogs. The experience in purchasing Eco-OHPs was affected by whether the respondents recognized the possibility of contributing to environmental preservation, availability of vendors, product safety, and the number of eco-friendly products purchased. @*Conclusion@#In order to expand the use of Eco-OHPs, various efforts such as promotion of eco-friendly characteristics, determination of related vendors, reliable analysis of product safety, and expansion of product experience opportunities are required.
RESUMO
Purpose@#: The COVID-19 pandemic has had a far-reaching impact on society. Understanding the changes perceived by medical students is meaningful in that it can suggest the direction of future changes in medical education. The purpose of this study is to investigate the impact of COVID-19 social distancing on psychosocial changes in medical students. @*Methods@#: Anxiety and depression caused by COVID-19, changes in fatigue caused by social distancing, areas where significant changes occurred, and changes in social activity participation and media use behavior among medical students who have experienced the COVID-19 pandemic for more than two years by an online survey. Two hundred twenty-one who are 1st and 2nd-year medical students responded, and we analyzed the results by frequency analysis, independent t-test, paired-sample t-test, and ANOVA. Also, we analyzed Post hoc tests with Tamhane T2, which does not assume equal variance. @*Results@#: The second year of medical school showed higher anxiety and depression than the first. The students who experienced COVID-19 showed lower anxiety, and the more severe the degree of corona blue experience, the higher the anxiety and depression. And the fatigue felt by medical students is higher now than during COVID-19. Areas where the changes due to COVID-19 were seen a lot, were lifestyle attitudes, learning methods, and human relationships. And also, social activities and media medical students use increased after social distancing. @*Conclusion@#: Before and After COVID-19 Social Distancing, medical students have experienced many psychosocial changes.
RESUMO
Transforaminal cervical epidural steroid injection (TFCESI) is widely used as conservative treatment for cervical radiculopathy, but severe complications associated with this procedure have been reported. This report was the first case of intramedullary spinal cord hemorrhage following TFCESI. A 67-year-old woman presented with weakness and sensory disturbance in left upper extremity after TFCESI. Cervical magnetic resonance imaging revealed intramedullary spinal cord hemorrhage accompanied by myelopathy at the C2∼C5 level. The patient was administered intravenous methylprednisolone daily (1,000 mg/8 hours) for 5 days and was subsequently transferred to the Department of Rehabilitation Medicine for rehabilitation therapy. A month later, the patient’s neurological impairment partially improved. Although TFCESI is rarely associated with major complications, physicians should be cautious when performing the procedure, and remain mindful of the potentially serious complications.
RESUMO
Methods@#This study was conducted in 134 patients with OVFs initially treated conservatively. The patients were split into two groups: 3-day and 7-day ABR. From the time of injury to 1, 4, and 12 weeks after injury, compression rate (CR) and local kyphotic angle (LKA) were assessed and compared between the two groups. Any complications such as pneumonia, deep vein thrombosis, delirium, and urinary tract infection known to be related to ABR were examined based on the electronic medical record. @*Results@#Forty-four patients underwent ABR for 3 days and 90 underwent ABR for 7 days. There was no significant difference in CR and LKA between the two groups at the time of injury versus 1, 4, and 12 weeks after injury. The patients were divided into two groups: those who received a 3-day ABR and those who received a 7-day ABR. CR and LKA were measured and compared between the two groups from the time of damage to 1, 4, and 12 weeks after injury. The ABR-related complication rate was 43.4% in the 7-day ABR group and 22.7% in 3-day ABR group (p=0.02). The duration of hospital stay was significantly shorter in the 3-day ABR group (12.8 days) than in the 7-day group (16 days) (p=0.01). @*Conclusions@#Considering radiological outcomes, prognosis, complications, patient convenience, and economic impact, a 3-day ABR period is appropriate for the conservative treatment of OVFs.
RESUMO
Background@#Muscle cramp is possibly related to peripheral nerve hyperexcitability (PNH), and one of the most debilitating symptoms frequently encountered in patients with liver cirrhosis. We investigated whether pregabalin, a gamma-aminobutyric acid analogue, can suppress neuronal excitability and reduce muscle cramps in cirrhotic patients. @*Methods@#We conducted a randomized, double-blind, placebo-controlled trial in which study participants with cirrhosis from a single tertiary center were enrolled. Primary endpoint was the relative change in cramp frequency from the run-in to standard dose treatment phase (4 weeks per each). Secondary endpoints included the responder rate, and the changes in cramp frequency during sleep, pain intensity, health-related quality of life (Liver Disease Quality of Life Instrument, Short Form-36) and electrophysiological measures of PNH. @*Results@#This study was terminated early because of insufficient accrual. 80% (n = 56) of the target number of participants (n = 70) were randomized to pregabalin (n = 29) or placebo (n = 27). Median baseline frequency of muscle cramps (interquartile range) was 5.8 (3.5–10) per week in the pregabalin group and 6.5 (4.0–10) in the placebo group (P = 0.970). The primary analysis showed a significant reduction in cramp frequency with pregabalin compared to placebo (−36% vs. 4.5% for the percentage change, P = 0.010). Secondary outcomes did not differ significantly between the two groups. Adverse effects with pregabalin were mainly dizziness and lethargy. @*Conclusion@#With multiple problems emerging from premature termination in mind, the results suggested an acceptable safety profile and favorable effect of pregabalin in reducing muscle cramps compared to placebo in cirrhotic patients.
RESUMO
Background@#We previously, reported that granulocyte-colony stimulating factor (G-CSF) reduces cardiomyocyte apoptosis in diabetic cardiomyopathy. However, the underlying mechanisms are not yet fully understood. Therefore, we investigated whether the mechanisms underlying of the anti-apoptotic effects of G-CSF were associated with autophagy using a rat model of diabetic cardiomyopathy. @*Methods@#Diabetic cardiomyopathy was induced in rats through a high-fat diet combined with low-dose streptozotocin and the rats were then treated with G-CSF for 5 days. Rat H9c2 cardiac cells were cultured under high glucose conditions as an in vitro model of diabetic cardiomyopathy. The extent of apoptosis and protein levels related to autophagy (Beclin-1, microtubule-binding protein light chain 3 [LC3]-II/LC3-I ratio, and P62) were determined for both models. Autophagy determination was performed using an Autophagy Detection kit. @*Results@#G-CSF significantly reduced cardiomyocyte apoptosis in the diabetic myocardium in vivo and led to an increase in Beclin-1 level and the LC3-II/LC3-I ratio, and decreased P62 level. Similarly, G-CSF suppressed apoptosis, increased Beclin-1 level and LC3-II/LC3-I ratio, and decreased P62 level in high glucose-induced H9c2 cardiac cells in vitro. These effects of G-CSF were abrogated by 3-methyladenine, an autophagy inhibitor. In addition, G-CSF significantly increased autophagic flux in vitro. @*Conclusion@#Our results suggest that the anti-apoptotic effect of G-CSF might be significantly associated with the up-regulation of autophagy in diabetic cardiomyopathy.
RESUMO
Purpose@#This study aims to design that using formative assessment as an instructional strategy in real-time online classes, and to explore the application of Bloom’s taxonomy in the development of formative assessment items. @*Methods@#We designed the instruction using formative assessment in real-time online classes, developed the items of formative assessment, analyzed the items statistically, and investigated students' perceptions of formative assessment through a survey. @*Results@#It is designed to consist of 2–3 learning outcomes per hour of class and to conduct the formative assessment with 1–2 items after the lecture for each learning outcome. Formative assessment was 31 times in the physiology classes (total 48 hours) of three basic medicine integrated. There were nine “knowledge” items, 40 “comprehension” items, and 55 “application” items. There were 33 items (31.7%) with a correct rate of 80% or higher, which the instructor thought was appropriate. As a result of the survey on students’ perceptions of formative assessment, they answered that it was able to concentrate on the class and that it was helpful in achieving learning outcomes. @*Conclusion@#The students focused during class because they had to take formative assessment immediately after the learning outcome lecture. “Integration of lesson and assessments” was maximized by solving the assessment items as well as through the instructor’s immediate explanation of answers. Through formative assessment, the students were able to utilize metacognition by learning what content they understood or did not understand. Items that consider Bloom’s taxonomy allow students to remember, understand, and apply to clinical contexts.
RESUMO
Purpose@#Endocrine therapy is the first-line treatment recommended for patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer without visceral crisis. However, this recommendation has not been followed clinically because of efficacy issues. In this study, the survival of patients with HR-positive/HER2-negative metastatic breast cancer was evaluated based on the following first-line treatment regimens: the combination of palbociclib plus letrozole, conventional endocrine therapy, or chemotherapy. @*Methods@#Medical records were reviewed for this retrospective analysis. Patients with HR-positive/HER2-negative metastatic breast cancer were included. Progression-free survival (PFS) and overall survival (OS) were compared based on first-line treatment regimens. @*Results@#A total of 184 patients were included in the analysis. The first-line treatments were palbociclib plus letrozole in 46 patients (25.0%), endocrine therapy in 40 patients (21.7%), and chemotherapy in 98 patients (53.3%). The PFS of the palbociclib plus letrozole group was significantly longer than that of the endocrine therapy (hazard ratio=3.43, p<0.001) and chemotherapy (hazard ratio=2.88, p=0.001) groups. No significant difference was observed between the endocrine therapy and chemotherapy groups (p=0.430). The OS of the palbociclib plus letrozole group was significantly longer than that of the endocrine therapy (hazard ratio=5.34, p=0.009) and chemotherapy (hazard ratio 4.23, p=0.043) groups. No significant difference was observed between the endocrine therapy and chemotherapy groups (p=0.451). @*Conclusion@#The combination regimen of palbociclib and letrozole could be recommended as the first-line treatment of choice in patients with HR-positive/HER2-negative metastatic breast cancer.
