ABSTRACT
Objective@#Electroconvulsive seizure (ECS) is a potent treatment modality for various neuropsychiatric diseases, including Parkinson disease (PD). Recent animal studies showed that repeated ECS activates autophagy signaling, the impairment of which is known to be involved in PD. However, the effectiveness of ECS on PD and its therapeutic mechanisms have not yet been investigated in detail. @*Methods@#Systemic injection of a neurotoxin 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP), which destroys dopaminergic neurons in the substantia nigra compacta (SNc), in mice was utilized to induce an animal model of PD. Mice were treated with ECS 3 times per week for 2 weeks. Behavioral changes were measured with a rotarod test. Molecular changes related to autophagy signaling in midbrain including SNc, striatum, and prefrontal cortex were analyzed with immunohistochemistry and immunoblot analyses. @*Results@#Repeated ECS treatments normalized the motor deficits and the loss of dopamiergic neurons in SNc of the MPTP PD mouse model. In the mouse model, LC3-II, an autophagy marker, was increased in midbrain while decreased in prefrontal cortex, both of which were reversed by repeated ECS treatments. In the prefrontal cortex, ECS-induced LC3-II increase was accompanied with AMP-activated protein kinase (AMPK)-Unc-51-like kinase 1-Beclin1 pathway activation and inhibition of mamalian target of rapamycin signaling which promotes autophagy initiation. @*Conclusion@#The findings revealed the therapeutic effects of repeated ECS treatments on PD, which could be attributed to the neuroprotective effect of ECS mediated by AMPK-autophagy signaling.
ABSTRACT
With the introduction of coronavirus disease 2019 (COVID-19) vaccines, the Korea Disease Control and Prevention Agency (KDCA) commissioned the National Academy of Medicine of Korea to gather experts to independently assess post-vaccination adverse events. Accordingly, the COVID-19 Vaccine Safety Research Committee (CoVaSC) was launched in November 2021 to perform safety studies and establish evidence for policy guidance. The CoVaSC established 3 committees for epidemiology, clinical research, and communication. The CoVaSC mainly utilizes pseudonymized data linking KDCA’s COVID-19 vaccination data and the National Health Insurance Service’s claims data. The CoVaSC’s 5-step research process involves defining the target diseases and organizing ad-hoc committees, developing research protocols, performing analyses, assessing causal relationships, and announcing research findings and utilizing them to guide compensation policies. As of 2022, the CoVaSC completed this research process for 15 adverse events. The CoVaSC launched the COVID-19 Vaccine Safety Research Center in September 2022 and has been reorganized into 4 divisions to promote research including international collaborative studies, long-/short-term follow-up studies, and education programs. Through these enhancements, the CoVaSC will continue to swiftly provide scientific evidence for COVID-19 vaccine research and compensation and may serve as a model for preparing for future epidemics of new diseases.
ABSTRACT
Objective@#To assess the contrast-enhanced CT and ultrasonography (US) findings of intracholecystic papillary neoplasm (ICPN) and determine the imaging features predicting ICPN associated with invasive carcinoma (ICPN-IC). @*Materials and Methods@#In this retrospective study, we enrolled 119 consecutive patients, including 60 male and 59 female, with a mean age ± standard deviation of 63.3 ± 12.1 years, who had pathologically confirmed ICPN (low-grade dysplasia [DP] = 34, high-grade DP = 35, IC = 50) and underwent preoperative CT or US. Two radiologists independently assessed the CT and US findings, focusing on wall and polypoid lesion characteristics. The likelihood of ICPN-IC was graded on a 5-point scale. Univariable and multivariable logistic regression analyses were performed to identify significant predictors of ICPN-IC separately for wall and polypoid lesion findings. The performances of CT and US in distinguishing ICPN-IC from ICPN with dysplasia (ICPN-DP) was evaluated using the area under the receiver operating characteristic curve (AUC). @*Results@#For wall characteristics, the maximum wall thickness (adjusted odds ratio [aOR] = 1.4; 95% confidence interval [CI]: 1.1–1.9) and mucosal discontinuity (aOR = 5.6; 95% CI: 1.3–23.4) on CT were independently associated with ICPN-IC.Among 119 ICPNs, 110 (92.4%) showed polypoid lesions. Regarding polypoid lesion findings, multiplicity (aOR = 4.0; 95% CI: 1.6–10.4), lesion base wall thickening (aOR = 6.0; 95% CI: 2.3–15.8) on CT, and polyp size (aOR = 1.1; 95% CI: 1.0–1.2) on US were independently associated with ICPN-IC. CT showed a higher diagnostic performance than US in predicting ICPN-IC (AUC = 0.793 vs. 0.676; p = 0.002). @*Conclusion@#ICPN showed polypoid lesions and/or wall thickening on CT or US. A thick wall, multiplicity, presence of wall thickening in the polypoid lesion base, and large polyp size are imaging findings independently associated with invasive cancer and may be useful for differentiating ICPN-IC from ICPN-DP
ABSTRACT
Objective@#To compare Octopus multipurpose (MP) electrodes, which are capable of saline instillation and direct tissue temperature measurement, and conventional electrodes for radiofrequency ablation (RFA) in porcine livers in vivo. @*Materials and Methods@#Sixteen pigs were used in this study. In the first experiment, RFA was performed in the liver for 6 minutes using Octopus MP electrodes (n = 15 ablation zones) and conventional electrodes (n = 12 ablation zones) to investigate the effect of saline instillation. The ablation energy, electrical impedance, and ablation volume of the two electrodes were compared. In the second experiment, RFA was performed near the gallbladder (GB) and colon using Octopus MP electrodes (n = 12 ablation zones for each) with direct tissue temperature monitoring and conventional electrodes (n = 11 ablation zones for each). RFA was discontinued when the temperature increased to > 60°C in the Octopus MP electrode group, whereas RFA was performed for a total of 6 minutes in the conventional electrode group. Thermal injury was assessed and compared between the two groups by pathological examination. @*Results@#In the first experiment, the ablation volume and total energy delivered in the Octopus MP electrode group were significantly larger than those in the conventional electrode group (15.7 ± 4.26 cm3 vs. 12.5 ± 2.14 cm3 , p = 0.027; 5.48 ± 0.49 Kcal vs. 5.04 ± 0.49 Kcal, p = 0.029). In the second experiment, thermal injury to the GB and colon was less frequently noted in the Octopus MP electrode group than that in the conventional electrode group (16.7% [2/12] vs. 90.9% [10/11] for GB and 8.3% [1/12] vs. 90.9% [10/11] for colon, p < 0.001 for all). The total energy delivered around the GB (2.65 ± 1.07 Kcal vs. 5.04 ± 0.66 Kcal) and colon (2.58 ± 0.57 Kcal vs. 5.17 ± 0.90 Kcal) were significantly lower in the Octopus MP electrode group than that in the conventional electrode group (p < 0.001 for all). @*Conclusion@#RFA using the Octopus MP electrodes induced a larger ablation volume and resulted in less thermal injury to the adjacent organs compared with conventional electrodes.
ABSTRACT
Objective@#We aimed to evaluate the efficacy of EmboTrap II in terms of first-pass recanalization and to determine whether it could yield favorable outcomes. @*Materials and Methods@#In this multicenter, prospective study, we consecutively enrolled patients who underwent mechanical thrombectomy using EmboTrap II as a front-line device. The primary outcome was the first pass effect (FPE) rate defined by modified Thrombolysis In Cerebral Infarction (mTICI) grade 2c or 3 by the first pass of EmboTrap II. In addition, modified FPE (mFPE; mTICI grade 2b–3 by the first pass of EmboTrap II), successful recanalization (final mTICI grade 2b–3), and clinical outcomes were assessed. We also analyzed the effect of FPE on a modified Rankin Scale (mRS) score of 0–2 at 3 months. @*Results@#Two hundred-ten patients (mean age ± standard deviation, 73.3 ± 11.4 years; male, 55.7%) were included. Ninetynine patients (47.1%) had FPE, and mFPE was achieved in 150 (71.4%) patients. Successful recanalization was achieved in 191 (91.0%) patients. Among them, 164 (85.9%) patients underwent successful recanalization by exclusively using EmboTrap II. The time from groin puncture to FPE was 25.0 minutes (interquartile range, 17.0–35.0 minutes). Procedure-related complications were observed in seven (3.3%) patients. Symptomatic intracranial hemorrhage developed in 14 (6.7%) patients. One hundred twenty-three (58.9% of 209 completely followed) patients had an mRS score of 0–2. Sixteen (7.7% of 209) patients died during the follow-up period. Patients who had successful recanalization with FPE were four times more likely to have an mRS score of 0–2 than those who had successful recanalization without FPE (adjusted odds ratio, 4.13;95% confidence interval, 1.59–10.8; p = 0.004). @*Conclusion@#Mechanical thrombectomy using the front-line EmboTrap II is effective and safe. In particular, FPE rates were high. Achieving FPE was important for an mRS score of 0–2, even in patients with successful recanalization.
ABSTRACT
Purpose@#Despite its well-known clinical importance, physician empathy (PE) has been variably defined and its concepts among cultures are yet to be studied. This study aimed to develop a conceptual framework of PE and explore influencing factors on physicians’ empathetic behavior in the Korean clinical context. @*Methods@#Forty-two faculty members and 67 residents participated in the two-round Delphi survey to arrive at a consensus regarding the conceptual framework of PE in 2019. To explore individual and external factors affecting physicians’ empathetic behavior, a Likert scale questionnaire based on an initial free-text response was administered to the same participants. @*Results@#The conceptual framework of PE among Korean doctors consisted of basic communication skills and attitudes, cognitively understanding of patients’ thoughts and emotions, and communicating the doctors’ understandings to patients. Individual attributes and system- and patient-factors were revealed as influencing factors for PE in real practice. The former included communication ability, self-awareness and management, humanism, clinical competence, and good personality traits. Excessive workload, time constraints, aggressive attitudes, and negative preconceptions towards doctors were perceived as inhibiting or hindering empathy in patient care. @*Conclusion@#PE in the Korean clinical context comprised behavioral and cognitive components. Individual attributes, as well as external factors including system- and patient-factors were identified to affect PE in clinical settings. Further studies are needed to enhance the conceptual clarity of PE and identify how to promote doctors’ empathetic practice even in less favorable healthcare environments.
ABSTRACT
Background@#Actinic keratosis (AK) is a common precancerous cutaneous lesion. There are various AK treatment methods; however, no specific method is considered superior. Most existing studies on AK treatment are Caucasian-based and include patients with multiple lesions. @*Objective@#This study aimed to compare the treatment duration, financial costs, and success rates of topically applied 5% 5-fluorouracil (5-FU) solution, 5% imiquimod (IMIQ) cream, and cryosurgery in the treatment of histologically proven single-lesion AK in Korean patients. @*Methods@#We retrospectively reviewed the medical records of patients with single-lesion AK at a single Korean center from January 2018 to February 2021. Each patient was treated using the three aforementioned local treatments. @*Results@#The study included 58 patients. Nineteen of 23 (82.6%), 27 of 27 (100%), and eight of eight patients (100%) were successfully treated after topical 5-FU, topical IMIQ, and cryosurgery, respectively. Further analysis on treatment success by subgroup revealed the following: mean number of outpatient visits, 3.78 vs. 4.41 vs. 3.75;mean treatment duration, 5.79 vs. 6.00 vs. 9.38 weeks; and mean total treatment cost, 79,380 vs. 170,023 vs. 173,116 won; for the 5-FU, IMIQ, and cryosurgery subgroups, respectively. The total treatment cost was significantly different among the subgroups (p≤0.001). @*Conclusion@#Topical IMIQ and cryosurgery were superior in terms of treatment efficacy, but considering its low cost, 5-FU may also be a reasonable option. Hence, an individualized approach to treating localized AK should be taken.
ABSTRACT
Background@#Staphylococcus lugdunensis is an emerging pathogen in skin and soft tissue infections. However, until recently, the role of S. lugdunensis as a skin pathogen remained underrated. @*Objective@#The purpose of this study was to investigate the clinical characteristics and antibiotic susceptibility of S.lugdunensis isolated from skin diseases. @*Methods@#This is a retrospective chart review of 48 cases in which S. lugdunensis was isolated from bacterial skin cultures between 2016 and 2021. @*Results@#Among the 48 patients, the mean age was 41.0 years, 54.2% were male, and 12.5% of the patients had immunosuppressive diseases. Nearly 87.4% of infections occurred below the waist and the dominant sources of isolation were epidermal cyst (31.3%) and hidradenitis suppurativa (29.2%). The rate of resistance of S. lugdunensis against β-lactam antibiotics were as follows: penicillin, 83.3%; oxacillin, 37.5%; and methicillin, 29.2%. @*Conclusion@# S. lugdunensis is emerging as one of the primary pathogens of skin infections. When S. lugdunensis is isolated, dermatologists should consider that it is not just a component of the skin flora but can also be a pathogen. If S. lugdunensis is identified as the cause of infection, it should be managed with appropriate antibiotic therapy.
ABSTRACT
Background@#Although competency-based education (CBE) is becoming a popular form of medical education, it has not been used to train residents. Recently, the Korean Society of Anesthesiologists completed a pilot implementation and evaluation of a CBE program.This study aims to outline the experience. @*Methods@#The chief training faculty from each hospital took a one-hour online course about CBE. Emails on the seven core competencies and their evaluation were sent ahead of a pilot core competency evaluation (CCE) to residents and faculty. The pilot CCE took place in late 2021, followed by a survey. @*Results@#A total of 68 out of 84 hospitals participated in the pilot CCE. The survey response rate was 55.9% (38/68) for chief training faculty, 10.2% (91/888) for training faculty, and 30.2% (206/683) for residents. More than half of the training faculty thought that CCE was necessary for the education of residents. Residents’ and training faculty’s responses about CCE were generally positive, although their understanding of CCE criteria was low. More than 80% of the hospitals had a defibrillator and cardiopulmonary resuscitation manikin while the rarest piece of equipment was an ultrasound vessel model. Only defibrillators were used in more than half of the hospitals. Thoughts about CCE were related to various factors, such as length of employment, location of hospitals, and the number of residents per grade. @*Conclusions@#This study’s results may be helpful in improving resident education quality to meet the expectations of both teaching faculty and residents while establishing CBE.
ABSTRACT
Objectives@#This study was conducted to investigate the relationship between personality and decision making in the group of young male depression patients. @*Methods@#Eighty-four male depression patients were subjected to the following test: Beck’s Depression Inventory-II (BDI-II), and Beck’s Anxiety Inventory (BAI), Korean Wechsler Adult Intelligence Scale-IV (K-WAIS-IV), Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Personality Assessment Inventory (PAI), Temperament Character Inventory-Revised Short version (TCI-RS), Delay Discounting Task (DDT), Game of Dice Task (GDT). Pearson’s correlation analysis was used to determine the association between DDT and GDT performance results and self-report examination. Multiple linear regression models were conducted to figure out the causal relationship between risky choice of GDT and the variables suspected of having a linear relationship. The collected data was analyzed using SPSS 21. @*Results@#PAI mania, borderline features, dominance and novelty seeking of TCI-RS were positively correlated with the number of risky choices of GDT. Full Scale Intelligence Quotient, BDI-II, BAI score had no significant correlation with DDT and GDT. There was also no correlation between DDT and GDT. @*Conclusions@#The results suggest that risk taking decision is related to personality traits such as novelty seeking, while inter-temporal choice is not related to personality aspects. It could be inferred that two different decision-making processes take place independently at different brain regions.
ABSTRACT
Purpose@#To evaluate the extent to which myopia correction decreases distant exodeviation in patients with intermittent exotropia (IXT) and myopia. @*Methods@#The medical records of patients with IXT who underwent myopia correction without surgical intervention were retrospectively reviewed. No patient evidenced anisometropia or amblyopia; all exhibited distant angles of deviation greater than 10 prism diopters (PD). The refractive errors of the eye with greater myopia were analyzed. Patients who underwent at least 3 months of follow-up were included. We recorded age, sex, the angle of deviation, the stereoacuity, and suppression status. Patients who did and did not evidence improvement were analyzed at 9 months in terms of change in the distant angle of deviation. @*Results@#A total of 30 patients were analyzed. The average age was 8.27 ± 2.59 years. There were 18 (60%) males and 12 (40%) females. Twenty-four (80%) exhibited statistically significant decreases in the distant angle of deviation after wearing glasses for 3 months; the average value was 5.54 ± 3.59 PD (range 2-16 PD) (p 9 months (1.17 ± 3.63 PD) (p = 0.129). In patients evidencing no improvement at 3 months, we found no significant change in the distant angle of deviation at either 3 months (3.00 ± 4.56 PD) (p = 0.102) or 9 months (-3.66 ± 4.41 PD) (p = 0.132). @*Conclusions@#Eighty percent of IXT patients with myopia exhibited significant decreases in the distant angle of deviation after wearing glasses for 3 months, and this was well-maintained after 9 months.
ABSTRACT
This study investigates the effect of working hours on the dietary behaviors and dietary quality of male industrial workers employed in rotating shifts. The survey was conducted from February to March 2022, enrolling 209 male workers operating in rotational shifts at industries in the Chungcheongnam-do region. Eating behavior and health awareness were investigated during the morning shift, afternoon shift, and night shift for the same subjects. The shift timings were found to be associated with dietary behavior, which had an impact on the dietary quality of workers. Negative effects of shift timings on diet and health were also perceived by the shift workers. The frequency of alcohol consumption was high during the morning shift, and the frequency of night time snack intake was high during the afternoon shift. During the night shift, there was decreased vegetable intake and increased ramyeon intake. Compared to the morning shift, a significant decrease in dietary quality scores was found during the night shift. The workers recognized that rotating shift work negatively affected health, eating habits and sleep. There was a high demand for providing a variety of menus and healthy night snacks in the company cafeteria. When nutritional counseling and educational health services were provided, the willingness to participate was high. Therefore, to improve the health and dietary quality of shift workers, there is a need to provide diets suitable for the working environment and the characteristics, and to provide nutrition management services.
ABSTRACT
Objectives@#This study examined the changes in anxiety and depressive symptoms in the parents of Korean adults with autism spectrum disorder (ASD) after participating in the Korean version of the Program for the Education and Enrichment of Relational Skills for Young Adults (PEERS ® -YA-K). @*Methods@#Forty-six parents were enrolled (mean age 54.7 years; 22 fathers and 24 mothers), of whom 27 participated in the PEERS ® -YA-K as social coaches. Participants completed self-report scales, including the Test of Young Adult Social Skills Knowledge (TYASSK), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Symptom Check-List-90-R (SCL-90-R). The scales were administered three times: before and after the 16-week program and 4 months after the program ended. Differences between participant variables at pretreatment, post-treatment, and follow-up were analyzed using paired-sample t-tests. @*Results@#Participants showed a significant improvement in their social skills knowledge (TYASSK) (:p<0.01). There was a significant improvement in the BAI and BDI scores of parents with severe depressive and anxiety symptoms at the baseline (p<0.05). Paternal paranoia and maternal hostility results also significantly improved on the SCL-90-R. @*Conclusion@#This study suggests that PEERS ® -YA-K can reduce parental anxiety and depressive symptoms. To the best of our knowledge, this is the first to compare the degree of depression and anxiety after PEERS ® -YA-K in parents of adults with ASD.
ABSTRACT
Background and Objectives@#The purpose of this study was to conduct a meta-analysis of the effects of intraoperative pharyngeal packing on postoperative nausea, vomiting, and sore throat in nasal surgery patients. @*Methods@#Databases were searched from inception to December 2022. Randomized controlled trials comparing saline-soaked pharyngeal packing (packing group) with no packing (control group) during intubation in patients undergoing nasal surgery were included. The primary outcomes of interest were the incidence of postoperative nausea, vomiting, and sore throat at 24 hours. @*Results@#Eleven studies, including a total of 931 patients, were included. There was no significant difference between the two groups in the incidence of postoperative nausea and vomiting and severity scores at 2, 6, and 24 hours postoperatively. The incidence of throat pain was higher in the packing group than in the control group immediately after surgery and at 24 hours postoperatively. However, no significant difference was observed between the two groups in the incidence of sore throat at 6 and 12 hours postoperatively. @*Conclusion@#Intraoperative saline-soaked pharyngeal packing did not significantly decrease postoperative nausea and vomiting. However, the use of pharyngeal packing was associated with a higher incidence of sore throat in the initial recovery period.
ABSTRACT
Background and Objectives@#We compared pain levels, cardiovascular parameters, and complications according to whether patients underwent nasal packing with non-absorbable or biodegradable materials. @*Methods@#Patients who underwent septoplasty from May 2015 to April 2020 were retrospectively reviewed. Numeric rating scale (NRS) scores for pain, blood pressure, and heart rate were measured three times (immediately after surgery, 6 hours later, and on postoperative day [POD] 1). We collected data on complications, including postoperative bleeding, septal hematoma, adhesions, septal perforation, and the recurrence of septal deviation. @*Results@#In total, 200 patients underwent septoplasty, of whom 100 underwent nasal packing with Merocel and 100 underwent packing with Nasopore. The summed NRS scores over the three time points did not differ significantly between the groups. The NRS scores at 6 hours after surgery were highest in both groups. The systolic and diastolic blood pressure and the heart rate immediately after surgery were significantly higher than before surgery in both groups. The blood pressure and heart rate at 6 hours after surgery and on POD 1 did not differ significantly from those before surgery in either group. The incidence of sleep disturbance, postoperative bleeding, septal hematoma, adhesions, septal perforation, and recurrence of septal deviation did not differ significantly between the two groups. @*Conclusion@#Although the level of postoperative pain and the cardiovascular parameters changed over time, we found no significant differences in pain, blood pressure, heart rate, or the complication rate according to whether patients underwent nasal packing with Nasopore or Merocel.
ABSTRACT
The application of minimally invasive surgery for gallbladder cancer (GBC) is yet controversial. This article discusses the techniques of laparoscopic and robotic extended cholecystectomy. A 69-year-old male diagnosed with cT1-2N0 GBC underwent laparoscopic surgery, and a 55-year-old male with cT2N1 GBC underwent robotic surgery after preoperative chemotherapy. Nonanatomical partial hepatectomy with lymphadenectomy was performed. Liver parenchymal dissection was performed using Cavitron Ultrasonic Surgical Aspirator laparoscopically and Maryland bipolar dissector and Harmonic scalpel robotically. The operation time was 180 and 220 minutes, and the estimated blood loss was 140 and 130 mL, respectively. The final pathologies were pT1bN0 and pT2aN1, for which patients received adjuvant chemotherapy. There was no evidence of recurrence at 33 and 18 months without complications. Both laparoscopic and robotic extended cholecystectomy can be safely performed with the robotic surgical system as an effective alternative for GBC requiring liver resection with radical lymphadenectomy
ABSTRACT
Peritoneal seeding of hepatocellular carcinoma (HCC) is incurable and has poor prognosis. A 68-year-old man underwent surgical resection for a 3.5 cm single nodular HCC at the tip of segment 3 and transarterial chemoembolization for a 1.5 cm-sized recurrent HCC at the tip of segment 6. 3 months later, an increasing 1 cm pelvic nodule on the rectovesical pouch warranted radiotherapy. Although it stabilized, a new 2.7 cm-sized peritoneal nodule in the right upper quadrant (RUQ) omentum appeared 3.5 years after radiotherapy. Hence, omental mass and small bowel mesentery mass excision were performed. 3 years later, recurrent peritoneal metastases in the RUQ omentum and rectovesical pouch progressed. 33 cycles of atezolizumab and bevacizumab treatment elicited stable disease response. Finally, laparoscopic left pelvic peritonectomy was performed without tumor recurrence. Herein, we present a case of HCC with peritoneal seeding that was successfully treated with surgery after radiotherapy and systemic therapy, leading to complete remission.
ABSTRACT
Dyslipidemia in patients with diabetes is an important treatment target as a modifiable risk factor for cardiovascular disease (CVD). Although the primary treatment goal for dyslipidemia is to control low-density lipoprotein cholesterol (LDL-C), achieving this goal remains suboptimal according to recent studies. It is important to set the target goal for LDL-C control based on an accurate risk assessment for CVD. Here, we summarize the latest evidence on lipid management in patients with diabetes and present a consensus of the Korean Diabetes Association and Korean Society of Lipid and Atherosclerosis on the treatment goals of LDL-C according to the duration of diabetes, presence of CVD, target organ damage, or major cardiovascular risk factors. In patients with type 2 diabetes mellitus (T2DM) and CVD, an LDL-C goal of <55 mg/dL and a reduction in LDL-C level by 50% or more from the baseline is recommended. For the primary prevention of CVD in patients with T2DM with a duration of diabetes ≥10 years, major cardiovascular risk factors, or target organ damage, an LDL-C goal of <70 mg/dL is recommended. In patients with T2DM with a duration of diabetes <10 years and no major cardiovascular risk factors, an LDL-C goal of <100 mg/dL is recommended.
ABSTRACT
Artificial intelligence (AI) is a field of computer science that equips machines with human-like intelligence and enables them to learn, reason, and solve problems when presented with data in various formats. Neurosurgery is often at the forefront of innovative and disruptive technologies, which have similarly altered the course of acute and chronic diseases. In diagnostic imaging, such as X-rays, computed tomography, and magnetic resonance imaging, AI is used to analyze images. The use of robots in the field of neurosurgery is also increasing. In neurointensive care units, AI is used to analyze data and provide care to critically ill patients. Moreover, AI can be used to predict a patient’s prognosis. Several AI applications have already been introduced in the field of neurosurgery, and many more are expected in the near future. Ultimately, it is our responsibility to keep pace with this evolution to provide meaningful outcomes and personalize each patient’s care. Rather than blindly relying on AI in the future, neurosurgeons should gain a thorough understanding of it and use it to enhance their patient care.
ABSTRACT
Objective@#: The goal of this study was to analyze the clinical outcomes of endoscopic third ventriculostomy (ETV) and endoscopic septostomy when shunt malfunction occurs in a patient who has previously undergone placement of a ventriculoperitoneal shunt. @*Methods@#: From 2001 to 2020 at Seoul National University Children's Hospital, patients who underwent ETV or endoscopic septostomy for shunt malfunction were retrospectively analyzed. Initial diagnosis (etiology of hydrocephalus), age at first shunt insertion, age at endoscopic procedure, magnetic resonance or computed tomography image, subsequent shunting data, and follow-up period were included. @*Results@#: Thirty-six patients were included in this retrospective study. Twenty-nine patients, 18 males and 11 females, with shunt malfunction underwent ETV. At the time of shunting, the age ranged from 1 day to 15.4 years (mean, 2.4 years). The mean age at the time of ETV was 13.1 years (range, 0.7 to 29.6 years). Nineteen patients remained shunt revision free. The 5-year shunt revisionfree survival rate was 69% (95% confidence interval [CI], 0.54–0.88). Seven patients, three males and four females, with shunt malfunction underwent endoscopic septostomy. At the time of shunting, the age ranged from 0.2 to 12 years (mean, 3.9 years). The mean age at the time of endoscopic septostomy was 11.9 years (range, 0.5 to 29.5 years). Four patients remained free of shunt revision or addition. The 5-year shunt revision-free survival rate was 57% (95% CI, 0.3–1.0). There were no complications associated with the endoscopic procedures. @*Conclusion@#: The results of our study demonstrate that ETV or endoscopic septostomy can be effective and safe in patients with shunt malfunction.
