RESUMO
BACKGROUND: Hepatitis B virus (HBV) vaccination in Vietnamese adults remains low and unequally distributed. We conducted a study on HBV-naïve adults living in Ho Chi Minh City, Viet Nam, to determine barriers associated with HBV vaccination uptake after removing the financial barrier by providing free coupons for HBV vaccination. METHODS: After being screened for HBsAg, anti-HBs, and anti-HBc, 284 HBV-naïve study participants aged 18 and over (i.e., negative for HBsAg, anti-HBs, and anti-HBc total) were provided free 3-dose HBV vaccine coupons. Next, study participants' receipt of 1st, 2nd, and 3rd doses of HBV vaccine was documented at a pre-specified study healthcare facility, where HBV vaccines were distributed at no cost to the participants. Upon study entry, participants answered questionnaires on sociodemographics, knowledge of HBV and HBV vaccination, and related social and behavioral factors. The proportions of three doses of HBV vaccine uptake and their confidence intervals were analyzed. Associations of HBV vaccine initiation with exposures at study entry were evaluated using modified Poisson regression. RESULTS: 98.9% (281 of 284) of study participants had complete data and were included in the analysis. The proportion of participants obtaining the 1st, 2nd, and 3rd doses of HBV vaccine was 11.7% (95% Confidence Interval [95% CI] 8.0-15.5%), 10.7% (95%CI 7.1-14.3%), and 8.9% (95%CI 5.6-12.2%), respectively. On the other hand, participants were more likely to initiate the 1st dose if they had adequate knowledge of transmission (adjusted relative risk [aRR] = 2.58, 95% CI 1.12-5.92), adequate knowledge of severity (aRR = 6.75, 95%CI 3.38-13.48), and annual health-checking seeking behavior (aRR = 2.04, 95%CI 1.07-3.87). CONCLUSION: We documented a low HBV vaccination uptake despite incentivization. However, increased vaccine initiation was associated with better HBV knowledge and annual health check-up adherence. When considering expanding HBV vaccination to the general adult population, we should appreciate that HBV knowledge is an independent predictor of vaccine uptake.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease that affects multiple organs. More than half of the patients with SLE have kidney involvement, and up to 10% of patients with lupus nephritis develop end-stage renal disease (ESRD). Central nervous system (CNS) involvement in SLE occurs in 21% to 95% of patients. Severe neurological manifestations such as seizures, cerebrovascular disease, meningitis, and cerebrovascular accidents can develop in childhood-onset SLE, but cerebral infections, such as brain abscess and hemorrhage, are seldom reported in lupus nephritis, even in adults. Here, we report a rare case of childhood-onset SLE with ESRD, a cerebral abscess, and hemorrhage. A 9-year-old girl diagnosed with lupus nephritis was administered high-dose steroids and immunosuppressant therapy to treat acute kidney injury (AKI) and massive proteinuria. The AKI deteriorated, and after 3 months, she developed ESRD. She received hemodialysis three times a week along with daily peritoneal dialysis to control edema. She developed seizures, and imaging showed a brain abscess. This was complicated by spontaneous cerebral hemorrhage, and she became unstable. She died shortly after the hemorrhage was discovered. In conclusion, CNS complications should always be considered in clinical practice because they increase mortality, especially in those with risk factors for infection.
RESUMO
Purpose@#To compare the Doppler sonographic findings of the left renal vein (LRV) of children diagnosed with nutcracker syndrome with and without orthostatic proteinuria. @*Methods@#Fifty and 53 consecutive children with and without orthostatic proteinuria, respectively, underwent renal Doppler ultrasonography examinations. The peak velocity (PV) was measured at the hilar portion of the LRV and between the aorta and superior mesenteric artery. Renal Doppler ultrasonography findings and clinical data including urine protein-to-creatinine ratio (UPCR) were compared according to the presence or absence of orthostatic proteinuria. @*Results@#Between the two groups, no significant differences were observed in terms of age or sex. The PV ratio between the aortomesenteric and hilar portions was 7.79±2.65 and 6.32±3.01 in children with and without orthostatic proteinuria, respectively (P=0.009). No significant differences were observed between the two groups in terms of the UPCR in the first morning urine sample. However, the UPCR in the afternoon urine sample was significantly higher in children with orthostatic proteinuria than in those without orthostatic proteinuria (0.49±0.46 vs. 0.11±0.04 mg/mg, P<0.001). Furthermore, the PV ratio between the aortomesenteric and hilar portions revealed a positive correlation with the ratio of UPCR of the afternoon and that of first morning urine samples (R=0.21, P=0.034). @*Conclusions@#This study suggests that there can be a significant correlation of the PV ratio between the aortomesenteric and hilar portion of the LRV with orthostatic proteinuria in pediatric patients with nutcracker syndrome.
RESUMO
Objective@#: The Act on Life-Sustaining Treatment (LST) decisions for end-of-life patients has been effective since February 2018. An increasing number of patients and their families want to withhold or withdraw from LST when medical futility is expected. This study aimed to investigate the status of the Act on LST decisions for patients with acute cerebrovascular disease at a single hospital. @*Methods@#: Between January 2017 and December 2021, 227 patients with acute cerebrovascular diseases, including hemorrhagic stroke (n=184) and ischemic stroke (n=43), died at the hospital. The study period was divided into the periods before and after the Act. @*Results@#: The duration of hospitalization decreased after the Act was implemented compared to before (15.9±16.1 vs. 11.2±18.6 days, p=0.127). The rate of obtaining consent for the LST plan tended to increase after the Act (139/183 [76.0%] vs. 27/44 [61.4%], p=0.077). Notably, none of the patients made an LST decision independently. Ventilator withdrawal was more frequently performed after the Act than before (52/183 [28.4%] vs. 0/44 [0%], p<0.001). Conversely, the rate of organ donation decreased after the Act was implemented (5/183 [2.7%] vs. 6/44 [13.6%], p=0.008). Refusal to undergo surgery was more common after the Act was implemented than before (87/149 [58.4%] vs. 15/41 [36.6%], p=0.021) among the 190 patients who required surgery. @*Conclusion@#: After the Act on LST decisions was implemented, the rate of LST withdrawal increased in patients with acute cerebrovascular disease. However, the decision to withdraw LST was made by the patient’s family rather than the patient themselves. After the execution of the Act, we also observed an increased rate of refusal to undergo surgery and a decreased rate of organ donation. The Act on LST decisions may reduce unnecessary treatments that prolong end-of-life processes without a curative effect. However, the widespread application of this law may also reduce beneficial treatments and contribute to a decline in organ donation.
RESUMO
Cerebrospinal fluid (CSF) rhinorrhea is a rare condition characterized by the leakage of CSF through the nose. The diagnosis is established through comprehensive history taking, brain imaging, and nasal endoscopy. Surgical intervention is considered a secondary option for CSF leakage when conservative treatments, including behavioral therapy, pharmacotherapy, or lumbar puncture, fail to elicit a response. In recent years, endoscopic intranasal surgery has been favored over craniotomy for such surgical treatment. When repairing CSF leakage defects via endoscopic intranasal surgery, autologous fat and muscle flaps are commonly employed. However, these grafts may lead to complications, including donor site infection, edema, and wound dehiscence. Therefore, in this article, we would like to introduce two cases of CSF rhinorrhea repair surgery using TachoComb. While previous studies have employed TachoComb as a supplementary material for the repair of CSF leak defects, in the cases we describe, the primary reconstruction of the defect area was achieved using TachoComb, supported by free grafts such as septal bone or turbinate mucosal flap, which were smaller than the size of the CSF leakage defects.
RESUMO
Background and Objectives@#This study aimed to determine the efficacy of prophylactic desmopressin administered via the intranasal or intravenous route in reducing intraoperative bleeding during nasal surgery. We conducted a meta-analysis of the relevant literature to investigate the role of preoperative desmopressin in minimizing bleeding complications associated with nasal surgery. @*Methods@#We screened the relevant literature published before February 2023. Nine articles that compared the perioperative use of desmopressin (treatment) with a placebo or no treatment (control) were included. The analyzed outcomes were intraoperative bleeding during nasal surgery and postoperative morbidity. @*Results@#The treatment group showed significant improvements in intraoperative bleeding, the surgical field, and surgeon satisfaction compared to the control group. However, the prophylactic use of desmopressin was associated with elevated blood pressure and decreased serum sodium levels compared to the control group. Nonetheless, no significant adverse effects were reported in the included studies. Subgroup analyses comparing the route of administration (intravenous vs. intranasal) and type of surgery (rhinoplasty vs. endoscopic sinus surgery) showed that desmopressin had a beneficial effect on intraoperative bleeding and the surgical field, regardless of the route of administration or type of surgery. @*Conclusion@#The prophylactic use of desmopressin for nasal surgery effectively reduced intraoperative bleeding, improved the surgical field, and increased surgeon satisfaction, with no significant adverse effects. However, caution should be exercised when administering desmopressin as it may cause an elevation in postoperative blood pressure in patients with cardiopulmonary problems.
RESUMO
The heart contains diverse endothelial cell types. We sought to characterize the endocardial endothelial cells (EECs), which line the chambers of the heart. EECs are relatively understudied, yet their dysregulation can lead to various cardiac pathologies. Due to the lack of commercial availability of these cells, we reported our protocol for isolating EECs from porcine hearts and for establishing an EEC population through cell sorting. In addition, we compared the EEC phenotype and fundamental behaviors to a well-studied endothelial cell line, human umbilical vein endothelial cells (HUVECs). The EECs stained positively for classic phenotypic markers such as CD31, von Willebrand Factor, and vascular endothelial (VE) cadherin. The EECs proliferated more quickly than HUVECs at 48 h (1310 ± 251 cells vs. 597 ± 130 cells, p = 0.0361) and at 96 h (2873 ± 257 cells vs. 1714 ± 342 cells, p = 0.0002). Yet EECs migrated more slowly than HUVECs to cover a scratch wound at 4 h (5% ± 1% wound closure vs. 25% ± 3% wound closure, p < 0.0001), 8 h (15% ± 4% wound closure vs. 51% ± 12% wound closure, p < 0.0001), and 24 h (70% ± 11% wound closure vs. 90% ± 3% wound closure, p < 0.0001). Finally, the EECs maintained their endothelial phenotype by positive expression of CD31 through more than a dozen passages (three populations of EECs showing 97% ± 1% CD31+ cells in over 14 passages). In contrast, the HUVECs showed significantly reduced CD31 expression over high passages (80% ± 11% CD31+ cells over 14 passages). These important phenotypic differences between EECs and HUVECs highlight the need for researchers to utilize the most relevant cell types when studying or modeling diseases of interest.

Plastic recycling is one of the most economical and environment-friendly solutions for effective plastic waste management. Triboelectric separation is one of beneficial methods to accomplish this. A method and device capable of analyzing the triboelectrification of materials with specific initial charges are proposed in this study. The process of triboelectrification is experimentally analyzed for various initial-charge conditions using the proposed method and device. The triboelectrification process can be divided into two groups depending on the initial-charge conditions. For the specific initial conditions, termed Group 2 in this work, it is observed that the initial charge of one material is first released into the control volume, following which the two materials exchange charges, unlike in the conventional triboelectrification process. This study is expected to provide valuable insights into triboelectrification analysis, thereby advancing the multistage plastic-separation processes.

Long double-stranded RNA (dsRNA)-mediated RNA interference (RNAi) has been a well-known mechanism against white spot syndrome virus (WSSV) in cultured shrimp. In the present study, we investigated the protective efficacy of dsRNAs targeting the ribonucleotide reductase 2 (rr2) gene of WSSV according to length and target sequence location. To produce different lengths of dsRNAs, the 640 bp rr2 fragment (fragment I) was split into two equal 320 bp fragments (fragment II and III), then each 320 bp fragment was redivided into two 160 bp fragments (fragment IV, V, VI, and VII). After the synthesis of seven kinds of dsRNA fragments, dsRNAs with the same length were mixed with each other, then used for the evaluation of dsRNA's length effect in Penaeus vannamei. The result showed that 160 bp long dsRNAs were as effective as 320 and 640 bp long dsRNAs in the protection of shrimp against WSSV infection, suggesting that the dsRNA length of 160 bp would be enough to be used as RNAi-mediated WSSV suppression in P. vannamei. However, as the 160 bp long dsRNAs used in the length effect experiment were not a single dsRNA population but a mixture of 160 bp dsRNA fragments covering the parent 640 bp long dsRNA, the sequence effect was not included in this RNAi efficacy. In the experiments to know the effect of not only length but also sequence of rr2-targeting long dsRNAs on the protective efficacy against WSSV, dsRNAs with a length of 640 bp (fragment I) and 320 bp (fragment II, III) showed a constant high defense ability, but the protection degree of long dsRNAs with a length of 160 bp was different depending on the kinds of the fragment, suggesting that the RNAi efficacy of some rr2-targeting long dsRNAs with a length of 160 bp might have sequences that are variable according to experimental conditions. In conclusion, this study showed that the protective ability of long dsRNAs in shrimp against WSSV infection can be affected by the length and sequence of the long dsRNAs.

Background and Objectives@#Although the shortage of donor is a common problem worldwide, a significant portion of unutilized hearts are classified as marginal donor (MD) hearts. However, research on the correlation between the MD and the prognosis of heart transplantation (HTx) is lacking. This study was conducted to investigate the clinical impact of MD in HTx. @*Methods@#Consecutive 73 HTxs during 2014 and 2021 in a tertiary hospital were analyzed.MD was defined as follows; a donor age >55 years, left ventricular ejection fraction 240 minutes, or significant cardiac structural problems. Preoperative characteristics and postoperative hemodynamic data, primary graft dysfunction (PGD), and the survival rate were analyzed. Risk stratification by Index for Mortality Prediction after Cardiac Transplantation (IMPACT) score was performed to examine the outcomes according to the recipient state. Each group was sub-divided into 2 risk groups according to the IMPACT score (low <10 vs. high ≥10). @*Results@#A total of 32 (43.8%) patients received an organ from MDs. Extracorporeal membrane oxygenation was more frequent in the non-MD group (34.4% vs. 70.7, p=0.007) There was no significant difference in PGD, 30-day mortality and long-term survival between groups. In the subgroup analysis, early outcomes did not differ between low- and high-risk groups. However, the long-term survival was better in the low-risk group (p=0.01). @*Conclusions@#The outcomes of MD group were not significantly different from non-MD group. Particularly, in low-risk recipient, the MD group showed excellent early and longterm outcomes. These results suggest the usability of selected MD hearts without increasing adverse events.
RESUMO
Resin-bonded fixed partial denture (RBFPD)as known as Maryland bridge is is a well-known conservative method for its minimized invasion of the teeth for an anterior single tooth edentulous area. Despite of its various advantages, RBFPD was not widespread because of its high debonding rates, non-esthetic look or weak structure for material property. Currently, with the introduction of zirconia to dental material for RBFPD, Maryland bridge entered upon a new phase. Zirconia surmounts poor esthetics of metal framework, having proper strength, and overcomes ceramic’s structural weakness, being sufficiently esthetic. In this case, edentulous area of maxillary left lateral incisor was restored using zirconia resin-bonded fixed partial denture. Restoration of missing tooth in anterior area was achieved using non-invasive and esthetic prosthesis, then we report this case as satisfactory results were obtained for both the operator and the patient.
RESUMO
Purpose@#De novo malignancy is common after liver transplantation (LT); however, there are limited reports on the clinical outcomes of gastric cancer surgery after LT. Our study aimed to investigate the feasibility and safety of gastric cancer surgery after LT. @*Methods@#Seventeen patients underwent gastric cancer surgery after LT at a single institution between January 2013 and June 2021. We retrospectively collected data on surgical complications, survival, and recurrence status of these cases. @*Results@#Fifteen patients (88.2%) underwent curative gastrectomy, with 10 open distal (66.7%) and 5 laparoscopic distal (33.3%) gastrectomies. Surgical and severe complication rates were 3 of 15 (20.0%) and 1 of 15 (6.7%), respectively. There were no significant differences between laparoscopic (33.3%) and open surgery (66.7%) in terms of operation time and complication rate. No surgery-related mortalities occurred. Immunosuppressants could be maintained without difficulty, and no suspicious acute rejection was identified during the perioperative period. There was 1 recurrence after curative surgery (recurrence rate, 6.7%), and the 5-year cancer-specific survival rate after curative surgery was 93.3%. @*Conclusion@#Laparoscopic gastrectomy can be safely done even after LT in terms of postoperative complications and graft safety.
RESUMO
Purpose@#BRCA1 and BRCA2 are among the most important genes involved in DNA repair via homologous recombination (HR). Germline BRCA1/2 (gBRCA1/2)-related cancers have specific characteristics and treatment options but conducting gBRCA1/2 testing and interpreting the genetic imprint are sometimes complicated. Here, we describe the concordance of gBRCA1/2 derived from a panel of clinical tumor tissues using next-generation sequencing (NGS) and genetic aspects of tumors harboring gBRCA1/2 pathogenic variants. @*Materials and Methods@#Targeted sequencing was performed using available tumor tissue from patients who underwent gBRCA1/2 testing. Comparative genomic analysis was performed according to gBRCA1/2 pathogenicity. @*Results@#A total of 321 patients who underwent gBRCA1/2 testing were screened, and 26 patients with gBRCA1/2 pathogenic (gBRCA1/2p) variants, eight patients with gBRCA1/2 variants of uncertain significance (VUS; gBRCA1/2v), and 43 patients with gBRCA1/2 wild-type (gBRCA1/2w) were included in analysis. Mutations in TP53 (49.4%) and PIK3CA (23.4%) were frequently detected in all samples. The number of single-nucleotide variants (SNVs) per tumor tissue was higher in the gBRCA1/2w group than that in the gBRCA1/2p group (14.81 vs. 18.86, p=0.278). Tumor mutation burden (TMB) was significantly higher in the gBRCA1/2w group than in the gBRCA1/2p group (10.21 vs. 13.47, p=0.017). Except for BRCA1/2, other HR-related genes were frequently mutated in patients with gBRCA1/2w. @*Conclusion@#We demonstrated high sensitivity of gBRCA1/2 in tumors analyzed by NGS using a panel of tumor tissues. TMB value and aberration of non-BRCA1/2 HR-related genes differed significantly according to gBRCA1/2 pathogenicity in patients with breast cancer.
RESUMO
Background@#We evaluated and compared South Korea’s total knee arthroplasty (TKA) reimbursement criteria set by Health Insurance Review and Assessment Service (HIRA) with other TKA appropriateness criteria to find additional criterion to improve its appropriateness by reviewing TKA inappropriate cases. @*Methods@#Two TKA appropriateness criteria and HIRA’s reimbursement criteria for TKA were adapted for use on patients undergoing TKA in one institute from December 2017 to April 2020. Preoperative data including 9 validated questionnaires on knee jointspecific parameters, age, and radiography were used. We categorized cases into appropriate, inconclusive, inappropriate groups and analyzed each group. @*Results@#Data on 448 cases that underwent TKA were examined. According to the HIRA’s reimbursement criteria, 434 cases (96.9%) were appropriate and 14 cases (3.1%) were inappropriate; superior to other TKA appropriateness criteria. The inappropriate group had Knee Injury and Osteoarthritis Outcome score (KOOS) pain, KOOS symptoms, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score, and Korean Knee score total score with worse symptoms compared to the appropriate group classified by HIRA’s reimbursement criteria. @*Conclusions@#In terms of insurance coverage, HIRA’s reimbursement criteria was more effective in providing healthcare access to patients who had the most pressing need for TKA compared to other TKA appropriateness criteria. However, we found the lower age limit and patient-reported outcome measures of other criteria as useful tools in improving appropriateness of the current reimbursement criteria.
RESUMO
Objective@#: With the recent increase in mechanical thrombectomy (MT) for acute ischemic stroke (AIS), the role of neurosurgeons in AIS treatment has become increasingly important. This study aimed to assess the outcomes of patients with AIS treated by neurosurgeons and neurologists in the emergency room (ER) of a tertiary hospital in South Korea. @*Methods@#: From January 2020 to June 2021, 536 patients with AIS within 24 hours of symptom onset were admitted to our hospital via the ER. Based on the type of doctors who provided initial care for AIS in the ER, patients were divided into two groups : (a) neurosurgeon group (n=119, 22.2%) and (b) neurologist group (n=417, 77.8%). @*Results@#: Intravenous tissue plasminogen activator (tPA) was administered in 82 (15.3%) of 536 patients (n=17 [14.3%] in the neurosurgeon group and n=65 [15.6%] in the neurologist group). The door-to-tPA time was not significantly different between both groups (median, 53 minutes; interquartile range [IQR], 45–58 vs. median, 54 minutes; IQR, 46–74; p=0.372). MT was performed in 69 patients (12.9%) (n=25, 36.2% in the neurosurgeon group and n=44, 63.8% in the neurologist group). The neurosurgeon group achieved a shorter door-to-puncture time than the neurologist group (median, 115 minutes; IQR, 107–151 vs. median, 162 minutes; IQR, 117–189; p=0.049). Good clinical outcomes (3-month modified Rankin Scale 0–2) did not differ significantly between the two groups (96/119 [80.7%] vs. 322/417 [77.2%], p=0.454). @*Conclusion@#: The neurosurgeon group showed similar door-to-treatment time and clinical outcomes to the neurologist group in patients with AIS in the ER. This study suggests that neurosurgeons have comparable abilities to care for patients with AIS in the ER.
RESUMO
Objective@#Stroke detection at the prehospital stage is critically important for the provision of rapid treatment to stroke patients. This study aimed to evaluate the effect of patient consciousness level on prehospital stroke screening (PSS) by the emergency medical service (EMS) provider. @*Methods@#This retrospective cross-sectional study was conducted using data collected from a linked database of NEDIS (National Emergency Department Information System) and the EMS database in three hospitals. Adult stroke patients who were admitted into the emergency department (ED) using 119 EMS ambulances from 2014 to 2018 were included. The prehospital level of consciousness of patients was evaluated by the EMS provider, and they were divided into two treatment groups: an alert group and a non-alert group (verbal, painful, and unresponsive). The study outcomes were positive results of PSS: the Los Angeles Prehospital Stroke Scale (LAPSS) and Cincinnati Prehospital Stroke Scale (CPSS). Logistic regression analysis was conducted to evaluate the effect of prehospital consciousness level on the PSS result. @*Results@#A total number of 3,422 stroke patients were included. The positive rate of LAPSS was 17.0% in the alert group and 8.8% in the non-alert group. The positive rate of CPSS was 35.7% in the alert group and 21.3% in the non-alert group. In the adjusted logistic regression model, in the non-alert group, the adjusted odds ratio (AOR) for LAPSS was 0.47 (95% confidence interval [CI], 0.38-0.59) and the AOR for positive CPSS was 0.49 (95% CI, 0.42-0.57). @*Conclusion@#Low consciousness level patients had lower detection of stroke by the EMS provider. EMS provider employees need additional training to achieve more effective detection of stroke in low consciousness level patients.
RESUMO
Objective@#This study aimed to investigate the association between the change in the National Early Warning Score (NEWS) before and after interhospital transport and the survival of critically ill patients transported by critical care transport. @*Methods@#A retrospective analysis of SMICU (Seoul Mobile Intensive Care Unit) transfer records and the National Emergency Department Information System (NEDIS) was conducted. Adult patients who used SMICU from 2016 to 2018 were included. Trauma patients and post-cardiac arrest patients were excluded. The NEWS before departure from the transferring hospital and the NEWS before the arrival at the receiving hospital were extracted, and the difference between both NEWS (△ NEWS) was calculated. The △ NEWS was categorized into three groups: -2 or less, -1 to 1, and 2 or more. The primary outcome was 24-hour post-transport mortality. Multivariable logistic regression was applied to calculate the adjusted odds ratio (AOR) and 95% confidence interval (CI) for the outcomes. @*Results@#Of the total number of 1,837 patients, 1,065 patients were included. △ NEWS were -2 or less in 131 (12.3%), -1 to 1 in 805 (75.6%), and 2 or more in 129 (12.1%) of the patients. The 24-hour mortality rate was 3.1%, 2.9%, and 7.0% in the △ NEWS≤-2, -1≤△ NEWS≤1, and △ NEWS≥2 groups, respectively. Relative to -1≤△ NEWS≤1, the AORs for the 24-hour mortality were 1.11 (95% CI, 0.38-3.29) in △ NEWS≤-2 and 2.56 (95% CI, 1.15-5.70) in △ NEWS≥2. @*Conclusion@#The changes in NEWS in critical care interhospital transport are associated with patient prognosis.
RESUMO
Objective@#It is unknown whether artificial intelligence-based computer-aided detection (AI-CAD) can enhance the accuracy of chest radiograph (CR) interpretation in real-world clinical practice. We aimed to compare the accuracy of CR interpretation assisted by AI-CAD to that of conventional interpretation in patients who presented to the emergency department (ED) with acute respiratory symptoms using a pragmatic randomized controlled trial. @*Materials and Methods@#Patients who underwent CRs for acute respiratory symptoms at the ED of a tertiary referral institution were randomly assigned to intervention group (with assistance from an AI-CAD for CR interpretation) or control group (without AI assistance). Using a commercial AI-CAD system (Lunit INSIGHT CXR, version 2.0.2.0; Lunit Inc.). Other clinical practices were consistent with standard procedures. Sensitivity and false-positive rates of CR interpretation by duty trainee radiologists for identifying acute thoracic diseases were the primary and secondary outcomes, respectively. The reference standards for acute thoracic disease were established based on a review of the patient’s medical record at least 30 days after the ED visit. @*Results@#We randomly assigned 3576 participants to either the intervention group (1761 participants; mean age ± standard deviation, 65 ± 17 years; 978 males; acute thoracic disease in 472 participants) or the control group (1815 participants; 64 ± 17 years; 988 males; acute thoracic disease in 491 participants). The sensitivity (67.2% [317/472] in the intervention group vs. 66.0% [324/491] in the control group; odds ratio, 1.02 [95% confidence interval, 0.70–1.49]; P = 0.917) and false-positive rate (19.3% [249/1289] vs. 18.5% [245/1324]; odds ratio, 1.00 [95% confidence interval, 0.79–1.26]; P = 0.985) of CR interpretation by duty radiologists were not associated with the use of AI-CAD. @*Conclusion@#AI-CAD did not improve the sensitivity and false-positive rate of CR interpretation for diagnosing acute thoracic disease in patients with acute respiratory symptoms who presented to the ED.
RESUMO
The tongue is one of the most common sites of oral cancer. Glossectomy is known as the gold standard for tongue cancer treatment. However, surgical removal can lead to reduced mobility of the tongue and the patients may have difficulty performing normal oral functions like swallowing and pronunciation. Therefore, additional prosthetic consideration to supplement the function of the impaired tongue is needed for oral rehabilitation of such patients. Palatal augmentation prosthesis helps the tongue to reach the palate by lowering the position of the palatal polished surface. The oral functions of the patients with limited tongue mobility can be improved by the prosthesis. In this case, palatal augmented maxillary denture and conventional mandibular denture were fabricated for the completely edentulous patient with reduced tongue mobility after glossectomy due to tongue cancer. As a result, the oral functions of the patient were improved with the prosthesis.
RESUMO
Cardiovascular disease (CVD) poses a significant health challenge globally, including in Korea, due to its status as a leading cause of death and its impact on cardiopulmonary function. Cardiac rehabilitation (CR) is a well-established program that not only aids in restoring cardiopulmonary function, but also improves physical and social conditions. The benefits of CR are widely recognized, and it is implemented globally. While the effectiveness of CR has been proven in Korea, it is underutilized. This fact sheet summarizes the current status of CR in Korea, including the prevalence of CVD, the clinical practice guidelines for CR programs, and the challenges of implementing CR in Korea.
