Abstract
Obesity is a potential risk factor for meniscal tear (MT). We utilized meta-analysis of observational studies and Mendelian randomization (MR) analyses to elucidate the association between body mass index (BMI) and MT. In meta-analysis, a search was performed on June 27, 2022, using PubMed and Embase databases. Odds ratios and 95% confidence intervals were extracted from included studies. In MR analyses, the research utilized summary-level data on BMI and MT obtained from Genetic Investigation of Anthropometric Traits and the FinnGen Consortium, respectively. In meta-analysis, four studies comprising 826,383 participants were included. The pooled odds ratio of MT in the high BMI group was 1.32 (95% confidence interval, 0.83-2.09), compared with the nonhigh BMI group. The pooled odds ratio in the under 30 group was 1.76 (95% confidence interval, 0.61-5.03). In MR analyses, one standard deviation increase in genetically predicted BMI was associated with meniscus derangement as a chronic subtype of MT (odds ratio, 1.36; 95% confidential interval, 1.17-1.59). We found that a high BMI was not associated with an increased likelihood of MT based on meta-analysis of observational studies; however, by complementing MR analyses, we elucidated the causality of BMI increase on meniscus derangement as a chronic subtype of MT.

Abstract
BACKGROUND Epilepsy, characterized by recurrent unprovoked seizures, poses significant challenges to affected individuals globally. While several established risk factors for epilepsy exist, the association with cigarette smoking remains debated. This study aims to conduct systematic review and meta-analysis to elucidate the potential association between smoking and the likelihood of epilepsy. METHODS The search was performed on March 31st, 2023, using the Medline, Embase, Web of Science, Scopus, and ScienceDirect. We included cohort, cross-sectional, and case-control studies in our meta-analysis, conducting subgroup analyses based on smoking history, sex, and epilepsy type to yield specific insights. RESULTS We identified 2550 studies, of which 17 studies were finally included in this study. The pooled odds ratio of epilepsy was 1.14 (0.96-1.36) in smokers compared to non-smokers. In current smokers compared to non-smokers, the odds ratio was 1.46 (1.13-1.89), while, in former smokers compared to non-smokers, the odds ratio was 1.14 (0.83-1.56). CONCLUSIONS While the overall association between smoking and epilepsy did not reach statistical significance, a notable association was found among current smokers. The study emphasizes the importance of smoking cessation as a potential preventive measure against epilepsy, especially given the proconvulsive effects of nicotine. Future research should address limitations and explore specific clinical scenarios to enhance our understanding of the complex relationship between cigarette use and epilepsy.

Abstract
INTRODUCTION Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder primarily affecting the voluntary motor nervous system. Several observational studies have provided conflicting results regarding the association between smoking and ALS. Therefore, our objective was to investigate this association through a systematic review, meta-analysis, and dose-response analysis. METHODS On 16 January 2023, we initially extracted records from medical databases, which included Medline, Embase, Web of Science, Scopus, and ScienceDirect. We included case-control and cohort studies as eligible studies. Subgroup analyses were performed based on sex, study design, and current smoking. Restricted cubic-spline analysis was utilized to assess the dose-response relationship between smoking (pack-years) and ALS. RESULTS Twenty-eight case-control and four cohort studies met the inclusion criteria. The unadjusted OR for the overall association between smoking and ALS was 1.14 (95% CI: 1.06-1.22, I2=44%, p<0.001), and the adjusted OR (AOR) was 1.12 (95% CI: 1.03-1.21, I2=49%, p=0.009). Subgroup analysis revealed a more pronounced association among current smokers, with an AOR of 1.28 (95% CI: 1.10-1.49, I2=66%, p<0.001) and AOR of 1.28 (95% CI: 1.10-1.48, I2=58%, p=0.001). In the dose-response analysis, the non-linear model revealed an inverted U-shaped curve. CONCLUSIONS Our study provides evidence of a positive relationship between smoking and the risk of ALS. To mitigate the risk of developing ALS, discontinuing smoking, which is a modifiable risk factor, may be crucial.TRIAL REGISTRATION: The study was registered in PROSPERO.IDENTIFIER: CRD42023388822.

Abstract
White blood cells (WBCs) act as mediators of inflammatory responses and are commonly measured in hospitals. Although several studies have reported a relation between WBC count and mortality, no systematic review or meta-analysis has been conducted. This study aimed to identify an association between WBC count and mortality. We conducted a systematic search on Embase using keywords such as "white blood cell" and "mortality." We analyzed the hazard ratios (HRs) for WBC count of 1.0 × 109 cells/L regarding 2 criteria: the cause of mortality and the follow-up period. A total of 13 of 222 articles comprising a total of 62,904 participants were included in this study, meeting the criteria set. A positive association was observed between WBC count and mortality, as indicated by an HR of 1.10 (95% confidence interval [CI] 1.08 to 1.13). In additionally, WBC count emerged as a significant predictor of mortality in both groups, with an HR of 1.10 (95% CI 1.07 to 1.12) for patients with cardiovascular disease and an HR of 1.12 (95% CI 1.07 to 1.17) for the general population or patients with COVID-19. Furthermore, a higher WBC count demonstrated a significant association with long-term all-cause mortality (HR 1.09, 95% CI 1.07 to 1.12) and long-term cardiovascular mortality (HR 1.05, 95% CI 1.02 to 1.07). Similarly, a significant association was found between higher WBC count and short-term all-cause mortality (HR 1.12, 95% CI 1.09 to 1.16) and cardiovascular mortality (HR 1.12, 95% CI 1.07 to 1.17). Further research is necessary to explore the relation between WBC count and disease progression or death and to establish causality between elevated WBC count and disease progression.

Abstract
Studies on inflammatory markers, endothelial activation, and bleeding during extracorporeal membrane oxygenation (ECMO) are lacking. Blood samples were prospectively collected after ECMO initiation from 150 adult patients who underwent ECMO for respiratory failure between 2018 and 2021. After excluding patients who died early (within 48 h), 132 patients were finally included. Their tumor necrosis factor-alpha (TNF-α), tissue factor (TF), soluble thrombomodulin (sTM), and E-selectin levels were measured. A Cox proportional hazards regression model was used to estimate the hazard ratio for hemorrhagic complications during ECMO. The 132 patients were divided into hemorrhagic (n = 23, H group) and non-complication (n = 109, N group) groups. The sequential organ failure assessment score, hemoglobin level, and ECMO type were included as covariates in all Cox models to exclude the effects of clinical factors. After adjusting for these factors, initial TNF-α, TF, sTM, E-selectin, and activated protein C levels were significantly associated with hemorrhagic complications (all p < 0.001). TNF-α, TF, and E-selectin better predicted hemorrhagic complications than the model that included only the aforementioned clinical factors (clinical factors only (area under the curve [AUC]: 0.804), reference; TNF-α (AUC: 0.914); TF (AUC: 0.915); E-selectin (AUC: 0.869)). Conclusions: TNF-α levels were significantly predictive of hemorrhagic complications during ECMO.

Abstract
Several studies have demonstrated an association between the risk asthma/allergic rhinitis and the environment. However, to date, no systematic review or meta-analysis has investigated these factors. We conducted a systematic review and meta-analysis to assess the association between urban/rural living and the risk of asthma and allergic rhinitis. We searched the Embase and Medline databases for relevant articles and included only cohort studies to observe the effects of time-lapse geographical differences. Papers containing information on rural/urban residence and respiratory allergic diseases were eligible for inclusion. We calculated the relative risk (RR) and 95% confidence interval (CI) using a 2 × 2 contingency table and used random effects to pool data. Our database search yielded 8388 records, of which 14 studies involving 50,100,913 participants were finally included. The risk of asthma was higher in urban areas compared to rural areas (RR, 1.27; 95% CI, 1.12-1.44, p < 0.001), but not for the risk of allergic rhinitis (RR, 1.17; 95% CI, 0.87-1.59, p = 0.30). The risk of asthma in urban areas compared to rural areas was higher in the 0-6 years and 0-18 years age groups, with RRs of 1.21 (95% CI, 1.01-1.46, p = 0.04) and 1.35 (95% CI, 1.12-1.63, p = 0.002), respectively. However, there was no significant difference in the risk of asthma between urban and rural areas for children aged 0-2 years, with a RR of 3.10 (95% CI, 0.44-21.56, p = 0.25). Our study provides epidemiological evidence for an association between allergic respiratory diseases, especially asthma, and urban/rural living. Future research should focus on identifying the factors associated with asthma in children living in urban areas. The review was registered in PROSPERO (CRD42021249578).

Abstract
Introduction Debate on the association between the use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) and the risk of developing cancer has been ongoing for decades. This study aimed to generate reliable results by analysing observational studies published in the decade after our last meta-analysis was conducted. Methods We searched Embase and Medline databases on 21 January 2021 for cohort and case-control studies. Two researchers independently reviewed the literature and assessed the title and abstract of each publication. The I2 statistic used to evaluate the heterogeneity of the effect measures. Risk of bias was qualitatively assessed using the Newcastle-Ottawa scale. Results and discussion We included an additional 16 cohort, 6 nested case-control, and 9 conventional case-control studies in the updated analysis. Overall HRs decreased, while overall relative risks increased. Conclusion Our results show some protective effects through the hazard ratio and some detrimental effects through the relative risk. Large-scale investigations of cohorts followed up for decades are needed to clarify association. Plain Language Summary Introduction: Two types of drug, angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), have been linked to the risk of developing cancer. We performed a meta-analysis by aggregating individual studies looking into the cancer risk of ACEIs and ARBs.Methods: We searched for articles on Embase and Medline databases until 21 January, 2021. Two researchers independently reviewed the literature and assessed the title and abstract of each publication.Results: Overall, the hazard ratio showed less than 1, while the relative risks showed higher than 1.Conclusion: Our results show some protective effects through the hazard ratio and some detrimental effects through the relative risk. Evidence supporting the risk of developing cancer is insufficient to prevent prescribing ACEIs or ARBs for patients with high blood pressure.

Abstract
BACKGROUND A previous 2014 meta-analysis reported a positive association between obesity and periodontitis. It was considered necessary to update the recently published papers and to analyse subgroups on important clinical variables that could affect the association between obesity and periodontitis. Therefore, we updated the latest studies and attempted to derive more refined results. METHODS All observational studies were eligible for inclusion. The Newcastle-Ottawa scale was used to qualitatively evaluate the risk of bias. Subgroup analyses were conducted for patients aged 18-34, 35-54, and 55+ years and the countries (European countries, USA, Brazil, Japan, Korea, and other Asian countries). RESULTS Thirty-seven full-text articles were included. Obesity conferred increased odds of periodontal disease with an odds ratio (1.35, 95% CI: 1.05-1.75). In the subgroup analysis by age, the odds ratio was the highest in the 18-34 years group (2.21, 95% CI: 1.26-3.89). In the subgroup analysis by country, European countries had the highest odds ratio (2.46, 95% CI: 1.11-5.46). CONCLUSION Despite the differences in degree, a positive association between obesity and periodontitis was found regardless of country or age. Therefore, medical professionals should try to prevent periodontitis by controlling patient weights, and more studies should be conducted to determine the association between obesity and oral health.

Abstract
Background With the introduction of Xpert MTB/RIF assay (Xpert), its incorporation into tuberculosis (TB) diagnostic algorithm has become an important issue. The aim of this study was to evaluate the performance of the Xpert assay in comparison with a commercial polymerase chain reaction (PCR) assay. Methods Medical records of patients having results of both Xpert and AdvanSure TB/NTM real-time PCR (AdvanSure) assays using the same bronchial washing specimens were retrospectively reviewed. Results Of the 1,297 patients included in this study, 205 (15.8%) were diagnosed with pulmonary TB. Using mycobacterial culture as the reference method, sensitivity of the Xpert assay using smear-positive specimens was 97.5%, which was comparable to that of the AdvanSure assay (96.3%, p=0.193). However, the sensitivity of the Xpert assay using smear-negative specimens was 70.6%, which was significantly higher than that of the AdvanSure assay (52.9%, p=0.018). Usng phenotypic drug susceptibility testing as the reference method, sensitivity and specificity for detecting rifampicin resistance were 100% and 99.1%, respectively. Moreover, a median turnaround time of the Xpert assay was 1 day, which was significantly shorter than 3 days of the AdvanSure assay (p<0.001). Conclusion In comparison with the AdvanSure assay, the Xpert assay had a higher sensitivity using smear-negative specimens, a shorter turnaround time, and could reliably predict rifampin resistance. Therefore, the Xpert assay might be preferentially recommended over TB-PCR in Korean TB diagnostic algorithm.

Abstract
Atelectasis is a reversible factor in hypoxemia among brain-dead donors. In ineligible donors, prone positioning reverses atelectasis and improves oxygenation. We present a successful lung transplantation after salvaging a previously unviable lung. A 37-year-old woman presented with acute pontine hemorrhage that progressed to brain death. The initial partial pressure of oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio of the donor’s lung was 342 mmHg. The PaO2/FiO2 ratio dropped to 49 mmHg due to atelectasis. There was no improvement despite recruitment maneuvers, bronchoscopy, and chest percussion. After placing the donor in the prone position for four hours, electrical impedance tomography showed improved atelectasis. The donor did not experience hemodynamic instability. The lung was transplanted into a patient with Kartagener’s syndrome with situs inversus. The surgical procedure was uneventful. He was successfully weaned from the mechanical ventilator on the second-day post-transplantation and was discharged from the hospital after 4 weeks.

Abstract
Tuberculosis (TB) remains a serious public health problem in Korea. Korea has the highest incidence rate (59 per 100,000 population) and the second-highest TB mortality rate (four per 100,000 population) among Organisation for Economic Cooperation and Development member countries. However, some progress has been made in TB control over the past decade. The notification rate of new TB cases has been gradually decreasing since reaching its highest rate in 2011 (78.9 per 100,000 population). In 2019, the notification rate of new TB cases was 46.4 per 100,000 population, with a reduction of 9.9% from the 2018 rate. Additionally, the number of multidrug-resistant TB cases decreased from 618 in 2018 to 580 in 2019. This progress is thought the result of various TB control programs including a TB public–private mix model, insurance coverage for TB management, and a contact investigation program. Despite the progress made, new challenges have also emerged. The predominant challenges lie in the relatively increasing burden of TB in the vulnerable population (aging, socio-economically vulnerable, and foreign-born population), the implementation of latent TB infection management, and the high rate of multidrug-resistant TB. Since 2019, the Korean government has been implementing the “Midterm strategies to strengthen TB prevention and management” based on the 2nd National Strategic Plan for Tuberculosis Control (2018-2022). This program will be a turning point of TB control in Korea. The results produced in 2023 is expected to be favorable.

Abstract
OBJECTIVES To demonstrate the feasibility and efficacy of the Google Glass as a tool to improve patient satisfaction and patient-physician communication for otolaryngology residents in the outpatient clinic setting. The primary outcome of the study was to improve patient satisfaction scores based on physician communication-related questions from Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys. STUDY DESIGN Prospective randomised trial. SETTING Tertiary care hospital. SUBJECT AND METHODS To evaluate the effect on patient satisfaction, five residents were recorded using the Google Glass in an outpatient clinic setting by 50 randomised patients. Modified surveys based on the CG-CAHPS survey were completed by patients at the conclusion of each clinic encounter. The recorded videos were evaluated by two independent faculties. Summarised data and video were distributed to each resident for review as the intervention. The residents were recorded again by 45 additional patients with evaluation by patients and faculties. RESULTS After intervention, the scores from faculty surveys regarding patient satisfaction including the subject of better explanations (P > 0.001), listening carefully (P > 0.001), addressing patient questions (P > 0.001), displaying respect (P > 0.001) and spending adequate time (P = 0.0005) all significantly improved, as well as overall performance (P = 0.014). The scores from patient surveys did significantly improve. CONCLUSION This study demonstrates the improvements in patient satisfaction and patient-physician communication can be achieved with the use of Google Glass as a first-person recording device in the outpatient otolaryngology clinic setting.

Abstract
BACKGROUND Children with autism spectrum disorder (ASD) experience a range of severity levels characterised as levels of support they need for everyday functioning. By this definition, greater levels of severity should warrant greater use of services and supports among children with ASD. In previous studies, Latino children with ASD in the USA have been shown to have lower access to diagnosis and treatment services than White children. However, none have examined service use in relation to severity. In this study, we examined whether there are ethnic disparities between Latino and White children with ASD in specialty autism-related services, and whether functional severity moderates the relationship between ethnicity and receipt of autism services. METHODS We used data from the Survey of Pathways to Diagnosis and Services, a supplement to the National Survey of Children with Special Health Care Needs and analysed four specialty services commonly used by children with ASD, adjusting for demographic variables. RESULTS We found that Latino children with ASD who had severe limitations received fewer specialty autism-related services than White children with similarly severe conditions. These disparities were evident despite the fact that the sample of Latino children in these data were more privileged than the general US Latino population. CONCLUSION Assertive policy initiatives are needed to address these disparities and ensure that these highly vulnerable children with severe functional limitations receive appropriate services and supports.

Abstract
BACKGROUND There is a critical need for evidence-based health education interventions for women with intellectual disabilities (IDs) to promote receipt of preventive health screenings. Previous research has established Women Be Healthy, an 8-week classroom-style intervention designed to teach women with IDs about breast and cervical cancer screenings, as a promising practice. However, additional research is needed to determine how to further improve screening-related knowledge gains. This study aimed to test a modified version of Women Be Healthy, Women Be Healthy 2, and compare its effectiveness in increasing knowledge gains to the original intervention. METHOD Women living in the community across one state in the United States were randomly assigned to a treatment (n = 98), delayed treatment, (n = 35), or no intervention group (n = 65). Women in the treatment group received Women Be Healthy, and women in the delayed treatment group received the modified Women Be Healthy 2. Baseline and post-intervention interviews were conducted to measure knowledge of cervical and breast cancer screening. Knowledge scores were compared across groups. RESULTS Among the nine knowledge items measured, one breast knowledge measure and one cervical knowledge measure showed statistically significant group differences; marginally significant differences were observed for two other knowledge measures. After adjusting for covariates, women who received Women Be Healthy 2 had increased knowledge overall compared with the women receiving no intervention. CONCLUSION Women Be Healthy 2 is promising, but additional efforts appear necessary to increase the knowledge women with IDs have about cervical and breast cancer screening.

Abstract
When lodgepole pines ( Pinus contorta Douglas ex Louden var. latifolia Engelm. ex S. Watson) that are killed by the mountain pine beetle ( Dendroctonus ponderosae ) and its fungal associates are not harvested, fungal decay can affect wood and fibre properties. Ophiostomatoids stain sapwood but do not affect the structural properties of wood. In contrast, white or brown decay basidiomycetes degrade wood. We isolated both staining and decay fungi from 300 lodgepole pine trees killed by mountain pine beetle at green, red, and grey stages at 10 sites across British Columbia. We retained 224 basidiomycete isolates that we classified into 34 species using morphological and physiological characteristics and rDNA large subunit sequences. The number of basidiomycete species varied from 4 to 14 species per site. We assessed the ability of these fungi to degrade both pine sapwood and heartwood using the soil jar decay test. The highest wood mass losses for both sapwood and heartwood were measured for the brown rot species Fomitopsis pinicola and the white rot Metulodontia and Ganoderma species. The sap rot species Trichaptum abietinum was more damaging for sapwood than for heartwood. A number of species caused more than 50% wood mass losses after 12 weeks at room temperature, suggesting that beetle-killed trees can rapidly lose market value due to degradation of wood structural components.

Abstract
Abstract
Background: Sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NAC) has been currently debatable. It is possible that the tumor response to chemotherapy may alter the lymphatic drainage thus causing lower SLN identification rate and higher false negative rate. Further, the response of NAC can be different in each lymph nodes. It is doubtful whether SLNB can accurately predict axillary lymph node (ALN) status after NAC. The aim of this study to determine the identification rate, the false-negative rate, and the accuracy of SLNB after NAC for node positive breast cancer.Patients and Methods: A prospective study was initiated to evaluate the results of SLNB after NAC. From January 2007 to April 2009, 81 patients with positive axillary lymph nodes enrolled from two institutions after IRB-approved. They received NAC and then evaluated negative conversion of metastatic lymph node with both PET and breast US. All of them underwent ALN dissection after SLNB with subareolar intradermal injection technique using radioisotope. We evaluated the identification rate, false negative rate, accuracy of SLNB according to the response of chemotherapy in axillary lymph nodes (negative conversion group or remaining positive group).Results: Before the NAC, 31 patients had multiple axillary lymph node metastasis and 50 patients had single metastasis. After NAC 44 cases (54.3%) turned into negative node and 37 cases (45.7%) remained positive nodes. Total identification rate was 80.2% (65 of 81), false negative rate was 19.0% (8 of 42) and accuracy was 87.7% (57 of 65). In negative conversion group showed 84.1% (37 of 44) of identification rate, 21.1% (4 of 19) of false negative rate, 89.2% (33 of 37) of accuracy. In remaining positive group revealed 75.7% (28 of 37) of identification rate, 17.4% (4 of 23) of false negative rate, 85.7% (24/28) of accuracy. There was no statistical significant difference of identification rate, false negative rate, accuracy of SLNB among the two group after NAC (p=0.343, p=0.534, p=0.478, respectively).Conclusion: This study showed relatively low detection rate and accuracy, high false-negative rate of SLNB, even if the positive nodes changed to negative node after NAC. Thus sentinel lymph node biopsy after NAC for node positive breast cancer should be cautious. Since this study had small number of negative conversion patients, further larger prospective studies are required for more proper conclusion.

Abstract
In an aqueous piperacillin sodium solution, a well-defined single wave or single peak was observed by direct current (DC) polarography or differential pulse polarography (DPP). The peak potential change per pH unit was -54 mV in the phosphate buffer at 18 degrees C, which indicated that protons were involved in the electrochemical reduction of the 2,3-dioxopiperazine moiety of piperacillin sodium with a H+/e- ratio of one. Using a phosphate buffer of pH 4.3, the 1.0 x 10(-7) M piperacillin sodium single peak could be determined by DPP with relative standard deviation of 1.6% (n=3). Piperacillin sodium could be analyzed without interference from penicillin G-potassium, which enabled the employment of DPP as a fast and simple technique for monitoring the synthetic process of the antibiotic.

Abstract
BACKGROUND This was a study of the relation of clinicopathological factors to prognosis in 25 patients who had ampullary carcinoma resected. METHODS The 5-year survival rate was six of the 25 patients. The presence of microperineural invasion was sought and related to outcome. RESULTS Factors relating to prognosis included tumour gross appearance, diameter, pancreatic invasion and microperineural invasion. The 5-year survival rate of 14 patients with microperineural invasion was 3, significantly worse than the 7 in 11 without invasion (P = 0.002, univariate analysis). By multivariate analysis, microperineural invasion was the most important prognostic factor (P = 0.02). Type of tumour recurrence was similar to that in pancreatic carcinoma. CONCLUSION Pancreaticoduodenectomy, rather than local resection, is the procedure of choice in patients with ampullary carcinoma.

Abstract
BACKGROUND/AIMS Based on our favorable results of interleukin-2-based immuno-chemotherapy in the treatment of unresectable liver metastases from colorectal cancer, we utilized this therapy for the prevention of liver recurrence after liver resection. MATERIALS AND METHODS Eighteen patients with colon cancer metastatic to the liver underwent successful hepatic resection and adjuvant immunochemotherapy that included hepatic arterial infusion of interleukin-2 and mitomycin C, 5-fluorouracil. The regimen consisted of weekly interleukin-2 (1.4-2x 10(6) units), 5-fluorouracil (250 mg) by 2-hour infusion and bolus mitomycin C (4 mg) for 6 months. RESULTS Fourteen of 18 patients are alive and disease-free with a median postoperative follow-up of 28.5 months. Recurrent cancer has developed in 4 of the 18 patients (22%). The site of first recurrence was the lung in three patients (17%) and the pelvis in one (6%); no patients recurred in the liver. CONCLUSIONS We recommend this adjuvant immuno-chemotherapy for the prevention of liver recurrence after curative resection of colorectal liver metastases.
