Abstract
BACKGROUND Erdafitinib is an oral pan-fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitor approved to treat locally advanced/metastatic urothelial carcinoma (mUC) in patients with susceptible FGFR3/2 alterations (FGFRalt) who progressed after platinum-containing chemotherapy. FGFR-altered tumours are enriched in luminal 1 subtype and may have limited clinical benefit from anti-programmed death-(ligand) 1 [PD-(L)1] treatment. This cohort in the randomized, open-label phase III THOR study assessed erdafitinib versus pembrolizumab in anti-PD-(L)1-naive patients with mUC. PATIENTS AND METHODS Patients ≥18 years with unresectable advanced/mUC, with select FGFRalt, disease progression on one prior treatment, and who were anti-PD-(L)1-naive were randomized 1 : 1 to receive erdafitinib 8 mg once daily with pharmacodynamically guided uptitration to 9 mg or pembrolizumab 200 mg every 3 weeks. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. RESULTS The intent-to-treat population (median follow-up 33 months) comprised 175 and 176 patients in the erdafitinib and pembrolizumab arms, respectively. There was no statistically significant difference in OS between erdafitinib and pembrolizumab [median 10.9 versus 11.1 months, respectively; hazard ratio (HR) 1.18; 95% confidence interval (CI) 0.92-1.51; P = 0.18]. Median PFS for erdafitinib and pembrolizumab was 4.4 and 2.7 months, respectively (HR 0.88; 95% CI 0.70-1.10). ORR was 40.0% and 21.6% (relative risk 1.85; 95% CI 1.32-2.59) and median duration of response was 4.3 and 14.4 months for erdafitinib and pembrolizumab, respectively. 64.7% and 50.9% of patients in the erdafitinib and pembrolizumab arms had ≥1 grade 3-4 adverse events (AEs); 5 (2.9%) and 12 (6.9%) patients, respectively, had AEs that led to death. CONCLUSIONS Erdafitinib and pembrolizumab had similar median OS in this anti-PD-(L)1-naive, FGFR-altered mUC population. Outcomes with pembrolizumab were better than assumed and aligned with previous reports in non- FGFR-altered populations. Safety results were consistent with the known profiles for erdafitinib and pembrolizumab in this patient population.

Abstract
PURPOSE/OBJECTIVE(S) To predict CRT response in locally advanced cervical cancer (LACC) with handcrafted radiomics (HCR) and deep learning radiomics (DLR) using pretreatment MRI. Furthermore, we investigate whether the incorporation of clinical factors improves prediction performance. MATERIALS/METHODS Two hundred and fifty-two patients with LACC are enrolled. All patients are treated with external beam radiotherapy, followed by high-dose-rate intracavitary brachytherapy with concurrent cisplatin. The patients are randomly divided into two independent groups for the training (167 patients) and test datasets (85 patients). Contrast-enhanced T1- and T2-weighted MR scans are obtained. Patients in the training and test sets have similar characteristics in terms of age, tumor size, FIGO stage, HPV infection status, or CRT response. For HCR analysis, 1890 imaging features are extracted and a support vector machine classifier with a five-fold cross-validation is trained using training dataset to predict CRT response and validated using test dataset. For DLR analysis, a 3-dimensional convolutional neural network was trained and validated using test dataset. RESULTS A comparison of the DLR and HCR models reveals that the DLR model exhibits better prediction performance than the HCR model for the test dataset (AUC = 0.721 vs. 0.597, p = 0.097). The incorporation of clinical factors could improve performance in both DLR and HCR models. CONCLUSION The DLR models outperform the HCR models in predicting CRT responses in patients with LACC. Combining clinical factors and MRI may improve the prediction performance in both HCR and DLR analyses.

Abstract
BACKGROUND Antibiotic resistance threatens public health worldwide, and inappropriate use of antibiotics is one of the main causes. AIM To evaluate qualitative use of antibiotics in asymptomatic bacteriuria (ABU) and urinary tract infection (UTI). METHODS Cases of positive urine culture (≥105 colony-forning units/mL) performed in inpatient, outpatient and emergency departments in April 2021 were screened in 26 hospitals in the Republic of Korea. The cases were classified as ABU, lower UTI and upper UTI. The appropriateness of antibiotic use was evaluated retrospectively by infectious disease specialists using quality indicators based on clinical guidelines for ABU and UTI. RESULTS This study included a total of 2697 patients with ABU or UTI. The appropriateness of antibiotic use was assessed in 1157 patients with ABU, and in 677 and 863 patients with lower and upper UTI, respectively. Among the 1157 patients with ABU, 251 (22%) were prescribed antibiotics without appropriate indications. In 66 patients with ABU in which antibiotics were prescribed with appropriate indications, the duration was adequate in only 23 (34.8%) patients. The appropriateness of empirical and definite antibiotics was noted in 527 (77.8%) and 353 (68.0%) patients with lower UTI, and 745 (86.3%) and 583 (78.2%) patients with upper UTI, respectively. The duration of antibiotics was adequate in 321 (61.8%) patients with lower UTI and 576 (78.7%) patients with upper UTI. CONCLUSIONS This nationwide qualitative assessment of antibiotic use in ABU and UTI revealed that antibiotics were often prescribed inappropriately, and the duration of antibiotics was unnecessarily prolonged.

Abstract
The objective of the current study was to conduct an initial comparison of commercial yeast products in layer hen diets on egg production parameters and the corresponding impact on the cecal microbiota. A short-term feeding study was conducted with 35 laying hens receiving either a control, or 1 of 4 different yeast fermentation products, Immunowall, Hilyses (both from ICC, São Paulo, Brazil), Citristim (ADM, Decatur, IL), and Maxi-Gen Plus (CBS Bio Platforms, Calgary, Canada) with 7 hens per treatment from 40 to 46 wk of age. At the end of the trial, hens were euthanized, the ceca removed and prepared for denatured gradient gel electrophoresis (DGGE) microbial compositional analyses. Although initial shell weight and shell thickness were similar among the treatment groups, hens fed Hilyses had lower shell weight and thickness at the end of the experiment. The most predominant DGGE bands with the strongest intensity were identified as Lactobacillus species and excised double bands were identified as Bacillus, Clostridium, or Lachnospiraceae. In this short-term feeding trial, the commercial yeast products tested had little effect on egg production and shell quality, and only moderately impacted the composition of mature layer hen cecal microbiota.

Abstract
BACKGROUND Obesity is associated with poor clinical outcomes in critically ill patients. However, under some clinical conditions, obesity has protective effects. Bloodstream infections (BSI) are among the most common nosocomial infections associated with extracorporeal membrane oxygenation (ECMO). BSI during ECMO is associated with higher mortality rates and poorer clinical outcomes. AIM To analyse whether body mass index (BMI) is associated with BSI during ECMO or with in-hospital mortality. METHODS All adult patients who had received ECMO support for >48 h were included in the analysis. The analysis of total duration of ECMO support, in-hospital mortality and BSI was stratified by BMI category. The Cox proportional hazards model was used to compare the risk of BSI among BMI categories. FINDINGS In total, 473 patients were enrolled in the study. The average age was 56.5 years and 65.3% were men. The total duration of ECMO was approximately 11.8 days, with a mortality rate of 47.1%. The incidence rates of BSI and candidaemia were 20.5% and 5.5%, respectively. The underweight group required ECMO for respiratory support, whereas the overweight and obese groups required ECMO for cardiogenic support (P<0.0001). No significant difference in BSI rate was found (P=0.784). However, after adjusting for clinical factors, patients in Group 4 (BMI 25.0-<30.0 kg/m2) exhibited lower mortality compared with patients in Group 2 (normal BMI) (P=0.004). CONCLUSION BMI was not associated with risk of BSI, but patients with higher BMI showed lower in-hospital mortality associated with ECMO support.

Abstract
Limited attention has been given to the role of cultural orientation towards different ethnic groups in multi-ethnic settings without a dominant host culture. We evaluated whether acculturation levels, reflecting cultural orientation towards other ethnic groups, were associated with obesity and related lifestyle behaviors in a cosmopolitan Asian population. We conducted the current study based on data from the Singapore Multi-Ethnic Cohort (N = 10,622) consisting of ethnic Chinese, Malays, and Indians aged 21 to 75 years. Multivariable linear and logistic regression analyses were used to examine associations between the acculturation level (z-score), obesity, and related lifestyle behaviors, including dietary habits and physical activity. A higher acculturation level was directly associated with a higher prevalence of obesity among Chinese, whereas an inverse association was found for ethnic Indians, and no significant association in Malays. In ethnic Malays, greater acculturation was significantly associated with higher dietary quality and less sedentary time. Furthermore, a high acculturation level was significantly associated with higher sugar-sweetened beverage consumption and more leisure-time PA in all ethnic groups. Our findings suggest that greater cultural orientation towards other ethnic groups was associated with convergence in obesity levels. More research is required to understand how acculturation affects obesity-related lifestyle factors in multi-ethnic settings.

Abstract
Background: Although there is limited literature on medication adherence (including HIV care engagement) and COVID-19 vaccine hesitancy in general populations (i.e., non-sexual or gender minority populations), even less is known about whether HIV care engagement correlates with COVID-19 vaccine hesitancy among sexual and gender minorities, especially those from intersectional backgrounds. The objective of the current study was to examine if an association exists between HIV status neutral care (i.e., current pre-exposure prophylaxis [PrEP] or antiretroviral therapy [ART] use) and COVID-19 vaccination hesitancy among Black cisgender sexual minority men and transgender women at the initial peak of the pandemic. Methods: We conducted the N2 COVID Study in Chicago from 20 April 2020 to 31 July 2020 (analytic n = 222), including Black cisgender sexual minority men and transgender women who were vulnerable to HIV as well as those who were living with HIV. The survey included questions regarding HIV care engagement, COVID-19 vaccination hesitancy and COVID-19 related socio-economic hardships. Multivariable associations estimated adjusted risk ratios (ARRs) using modified Poisson regressions for COVID vaccine hesitancy adjusting for baseline socio-demographic characteristics and survey assessment time period. Results: Approximately 45% of participants reported COVID-19 vaccine hesitancy. PrEP and ART use were not associated with COVID-19 vaccine hesitancy when examined separately or combined (p > 0.05). There were no significant multiplicative effects of COVID-19 related socio-economic hardships and HIV care engagement on COVID-19 vaccine hesitancy. Conclusions: Findings suggest no association between HIV care engagement and COVID-19 vaccine hesitancy among Black cisgender sexual minority men and transgender women at the initial peak of the pandemic. It is therefore essential that COVID-19 vaccine promotion interventions focus on all Black sexual and gender minorities regardless of HIV care engagement and COVID-19 vaccine uptake is likely related to factors other than engagement in HIV status neutral care.

The aim of this study was to comparatively evaluate the efficacy and safety of esomeprazole with sodium bicarbonate and esomeprazole alone. Methods This was a multicenter, randomized, double-blind, active-controlled, noninferiority comparative study. A total of 379 patients with NERD were randomly allocated to receive either EsoduoⓇ (esomeprazole 20 mg with sodium bicarbonate 800 mg) or NexiumⓇ (esomeprazole 20 mg) once daily for 4 weeks from January 2019 to December 2019. The patients had a history of heartburn for at least 2 days in the week before randomization as well as in the last 3 months and no esophageal mucosal breaks on endoscopy. The primary endpoint was a complete cure of heartburn at week 4. The secondary and exploratory endpoints as well as the safety profiles were compared in the groups at weeks 2 and 4. Results A total of 355 patients completed the study (180 in the EsoduoⓇ group and 175 in the NexiumⓇ group). The proportions of patients without heartburn in the entire 4th week of treatment were not different between the two groups (33.33% in the EsoduoⓇ group and 35% in the NexiumⓇ group, p=0.737). There were no significant differences in most of the secondary and exploratory endpoints as well as the safety profiles. Conclusions EsoduoⓇ is as effective and safe as NexiumⓇ for managing typical symptoms in patients with NERD (ClinicalTrial.gov identifier: NCT03928470).

Abstract
OBJECTIVES Despite the high prevalence of tuberculosis (TB) and the disease burden of osteoporosis and osteoporotic fractures, there is still a lack of well-designed, large-scale studies demonstrating associations among them. We aimed to investigate the effect of TB on the incidence of osteoporosis and osteoporotic fractures. STUDY DESIGN This was a nationwide population-based cohort study. METHODS This study was conducted using the National Health Insurance Service Database of South Korea. We included patients with newly diagnosed TB aged >40 years from January 2006 to December 2017. An uninfected control for each TB patient was randomly extracted by frequency matching for sex, age, income level, residence, and registration date at a 2:1 ratio. The primary outcome was the incidence of osteoporosis and osteoporotic fractures between the two groups, adjusted for sex, age, income level, residence, comorbidities, body mass index, blood pressure, laboratory tests, alcohol drinking, and smoking. The risk factors associated with osteoporosis or osteoporotic fractures were also investigated. RESULTS A total of 164,389 patients with TB and 328,778 matched controls were included (71.9% males). The mean duration of follow-up was 7.00 ± 3.49 years. The incidence of osteoporosis in patients with TB was 6.1 cases per 1000 person-years, which was significantly higher than that in matched controls (adjusted hazard ratio [aHR] 1.349, 95% confidence interval [CI] 1.302-1.398, P < 0.001). The incidence of osteoporotic fractures was also higher in patients with TB than in controls (aHR 1.392, 95% CI 1.357-1.428, P < 0.001). Among fractures, the risk of hip fracture was the highest (aHR 1.703, 95% CI 1.612-1.798, P < 0.001). CONCLUSIONS TB independently contributes to the incidence of osteoporosis and osteoporotic fractures, particularly hip fractures.

Objectives
Conflicting results regarding sex-based differences in the outcomes of out-of-hospital cardiac arrest (OHCA) patients have been reported. Furthermore, no study has examined whether differences in in-hospital interventions and courses are driven by sex differences. This study evaluated the effect of sex on the in-hospital course of these patients as well as the survival rates and long-term neurological outcomes of comatose OHCA patients treated with targeted temperature management (TTM).
Methods
We retrospectively analyzed the Korean Hypothermia Network prospective registry composed of data collected from 22 hospitals in Korea between October 2015 and December 2018. To evaluate the effect of sex on patient outcomes, we created various multivariate logistic regression models including baseline characteristics, resuscitation, and in-hospital care variables with an interaction term (age × sex). We also performed a stratified analysis of different age groups (less than 50 years of age and older). Regarding the difference in in-hospital courses, we compared daily total and SOFA sub-scores between the sexes and analyzed whether the decision regarding early cardiac interventions and limitations in in-hospital care were associated with sex.
Results
Among 1339 patients included in the study, 952 were men and 387 were women. There were no differences in age or modified comorbidity index values between the gender groups. Women were more likely to experience cardiac arrest at home and unwitnessed arrests, whereas men were more likely to have shockable initial rhythm, cardiac cause arrest, and ST-segment elevation myocardial infarction (STEMI) on initial electrocardiography and undergo early coronary interventions. The rate of survival to discharge was similar, but men showed better 6-month neurological outcomes. After adjusting for confounders, the male sex was not associated with survival to discharge or good 6-month neurological outcomes. There was no association between sex and outcome in patients of reproductive age and no interaction between age and sex. Regarding the in-hospital course, the daily total and SOFA sub-scores were similar in both sexes. The adjusted effect of sex was not associated with the clinician’s decision to perform early cardiac interventions. The decision to discontinue life-sustaining treatment was determined by poor prognostic factors, not by sex.
Conclusions
The findings suggested that men had more favorable 6-month survivals and good neurological outcomes compared to women since they had more favorable resuscitation variables. However, after adjusting for confounders, there was no difference between the sexes. This result was consistent with the data in patients of reproductive age. The results regarding in-hospital course showed that daily patient severity scores, early cardiac interventions, resource consumption, and the rates of withdrawal/withholding of in-hospital care were similar in men and women.

Abstract
OBJECTIVE To perform a systematic review of case reports or case series regarding thrombosis with thrombocytopenia syndrome (TTS) and cerebral venous thrombosis (CVT) related to ChAdOx1 nCoV-19 vaccination to address the clinical features, laboratory findings, treatment modalities, and prognosis related with CVT. SUBJECTS AND METHODS We included 64 TTS patients from 19 articles, 6 case series and 13 case reports, in which thrombosis occurred after the first dose of ChAdOx1 nCoV-19 vaccination published up to 30 June 2021 in Embase, ePubs, Medline/PubMed, Scopus, and Web of Science databases. RESULTS Of the 64 TTS patients, 38 (59.3%) had CVT. Patients with CVT were younger (median 36.5 vs. 52.5 years, p<0.001), had lower fibrinogen levels (130 vs. 245 mg/dL, p=0.008), had more frequent history of intracerebral hemorrhage (ICH), and had higher mortality rate (48.6% vs. 19.2%, p=0.020) than that of patients without CVT. In multivariable analysis, the possibility of presence of CVT was higher in younger age groups [odd ratio (OR): 0.91, 95% confidence interval (CI): (0.86-0.97, p<0.001)] and those with accompanying intracerebral hemorrhage (ICH) (OR: 13.60, 95% CI (1.28-144.12, p=0.045). CONCLUSIONS Our study demonstrated that CVT related to ChAdOx1 nCoV-19 vaccination was associated with younger age, low levels of fibrinogen, presence of ICH and more frequent mortality compared to those of non-CVT. If TTS occurs after ChAdOx1 nCoV-19 vaccination, the presence of CVT in patients with young age or ICH should be considered.

Abstract
OBJECTIVES To determine the association between individual, network, and structural COVID-19-related stressors and changes in sleep duration and quality among Black cisgender sexual minority men (SMM) and Black transgender women during the COVID-19 peak infectivity rate in Chicago. METHODS From April 20, 2020 to July 31, 2020, we conducted the N2 COVID Study in Chicago (n = 226). The survey included questions regarding multi-level COVID-19-related stressors (eg, food unavailability, partner violence, housing instability, concern about neighborhood COVID-19), sleep duration, and sleep quality. RESULTS About 19.5% of our sample reported a shorter duration of sleep during the initial peak COVID-19 infectivity, while 41.2% reported more sleep and 38.9% reported about the same. Compared to the prepandemic period, 16.8% reported that their sleep quality worsened in the COVID-19 pandemic, while 27.9% reported their sleep quality had improved and 55.3% reported it was about the same. In multivariable models, we found that ≥1 day of physical stress reaction, worrying about being infected with COVID-19, traveling during COVID-19 being a financial burden, not having enough medication, knowing someone who was diagnosed with COVID-19, partner violence and housing instability were associated with poor sleep health in the COVID-19 pandemic (adjusted risk ratio: 1.82-3.90, p < .05). CONCLUSIONS These data suggest that COVID-19-related stressors impacted poor sleep duration and quality during the pandemic among this cohort. Multi-level interventions to reduce COVID-19-related stressors (eg, meditation, intimate partner violence prevention and housing programs) may be useful for improving sleep health among Black cisgender sexual minority men and Black transgender women.

Abstract
Inflammatory bowel diseases are chronic, relapsing inflammatory disorders of the gastrointestinal tract with variable disease courses and complications, which in some cases can result in significant morbidities and disabilities. Etiologies remain unclear due to complex interactions between genetic and environmental factors. Considering the heterogeneity of inflammatory bowel diseases, personalized approaches in diagnosing and managing affected patients would be beneficial in maximizing treatment efficacies and minimizing adverse events. Personalized medicine may also help to stratify patients with a high risk of progression and inflammatory bowel disease-related complications and identify sub-phenotypic mechanisms to facilitate drug discovery and the development of new treatments. In Asia, with a rapidly increasing incidence and prevalence of inflammatory bowel diseases, studies have shown that patients of Asian ethnicity differ from their Western counterparts in terms of genetic and clinical aspects of inflammatory bowel diseases. Therefore, personalized medicine may differ for patients of Asian ethnicity with inflammatory bowel diseases. We reviewed and summarized current evidence concerning personalized medicine for the diagnosis and management of patients with inflammatory bowel diseases and its possible role from an Asian perspective.

Abstract
This study explored the prognostic and therapeutic potentials of multiple Proteasome 26S Subunit, ATPase (PSMC) family of genes (PSMC1-5) in lung adenocarcinoma (LUAD) diagnosis and treatment. All the PSMCs were found to be differentially expressed (upregulated) at the mRNA and protein levels in LUAD tissues. The promoter and multiple coding regions of PSMCs were reported to be differentially and distinctly methylated, which may serve in the methylation-sensitive diagnosis of LUAD patients. Multiple somatic mutations (alteration frequency: 0.6–2%) were observed along the PSMC coding regions in LUAD tissues that could assist in the high-throughput screening of LUAD patients. A significant association between the PSMC overexpression and LUAD patients’ poor overall and relapse-free survival (p < 0.05; HR: >1.3) and individual cancer stages (p < 0.001) was discovered, which justifies PSMCs as the ideal targets for LUAD diagnosis. Multiple immune cells and modulators (i.e., CD274 and IDO1) were found to be associated with the expression levels of PSMCs in LUAD tissues that could aid in formulating PSMC-based diagnostic measures and therapeutic interventions for LUAD. Functional enrichment analysis of neighbor genes of PSMCs in LUAD tissues revealed different genes (i.e., SLIRP, PSMA2, and NUDSF3) previously known to be involved in oncogenic processes and metastasis are co-expressed with PSMCs, which could also be investigated further. Overall, this study recommends that PSMCs and their transcriptional and translational products are potential candidates for LUAD diagnostic and therapeutic measure discovery.

Abstract
Jordan, a Middle Eastern country, initially responded to an outbreak of COVID-19 cases within its own borders by imposing a 7-week strict lockdown and closure of international and domestic travel. Such measures drastically influenced lifestyle behaviors of the population. This study aimed to investigate the prevalence of physical activity, and its association with mental and sleep health outcomes among Jordanians during a period of COVID-19 induced lockdown. Validated questionnaires were administered using a web-based platform to evaluate moderate-to-vigorous physical activity (MVPA), anxiety and depressive symptoms, sleep health, and sociodemographic characteristics. A modified Poisson regression model with robust error variance was used to estimate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs). Compared to participants who met the guidelines, those who did not had significantly higher prevalence of moderate or severe anxiety symptoms than that of minimal or mild anxiety symptoms and increased depressive symptoms. Insufficient MVPA was associated with higher prevalence of poor sleep quality, short sleep duration (<7 h) and sleep problems. Overall, sufficient MVPA was associated with better mental and sleep health during the COVID-19 induced nation-wide lockdown in Jordan. While further research is necessary, promoting physical activity during the lockdown could potentially improve mental and sleep health outcomes among the population.

Abstract
Background Modifiable risk factors for non-communicable diseases, including eating an unhealthy diet and being physically inactive, are influenced by complex and dynamic interactions between people and their social and physical environment. Therefore, understanding patterns and determinants of these risk factors as they occur in real life is essential to enable the design of precision public health interventions. Objective This paper describes the protocol for the Continuous Observations of Behavioural Risk Factors in Asia study (COBRA). The study uses real-time data capture methods to gain a comprehensive understanding of eating and movement behaviours, including how these differ by socio-demographic characteristics and are shaped by people's interaction with their social and physical environment. Methods COBRA is an observational study in free-living conditions. We will recruit 1500 adults aged 21-69 years from a large prospective cohort study. Real-time data capture methods will be used for nine consecutive days: an ecological momentary assessment app with a global positioning system enabled to collect location data, accelerometers to measure movement, and wearable sensors to monitor blood glucose levels. Participants receive six EMA surveys per day between 8 a.m. and 9.30 p.m. to capture information on behavioural risk factors including eating behaviours and diet composition movement behaviours (physical activity, sedentary behaviour, sleep), and related contextual factors. The second wave of ecological momentary assessment surveys with a global positioning system enabled will be sent 6 months later. Data will be analysed using generalised linear models to examine associations between behavioural risk factors and contextual determinants. Discussion Findings from this study will advance our understanding of dietary and movement behaviours as they occur in real-life and inform the development of personalised interventions to prevent chronic diseases.

Abstract
OBJECTIVE We aimed to evaluate the reliability and validity of the adapted Korean version of the Quality-of-Life Profile for Spine Deformities (QLPSD) questionnaire. PATIENTS AND METHODS English version of QLPSD was translated into Korean according to previously published guidelines. The Korean version of the QLPSD questionnaire and the Korean version of the SRS-22 was sent to 120 consecutive idiopathic scoliosis patients wearing braces recruited from the outpatient clinic. Reliability assessment and construct validity were evaluated. RESULTS The intraobserver reliability of all items in the questionnaire had a kappa statistic of agreement greater than 0.6. The QLPSD showed good test/re-test reliability (ICC = 0.815). The internal consistency of Cronbach's α was found to be very good (α = 0.918). The Korean version of QLPSD showed a significant correlation with the SRS-22 total score (p<0.001, r=-0.811) and single SRS-22 domains scores. CONCLUSIONS The adapted Korean version of the QLPSD was successfully translated and showed good measurement properties. As such, it is considered suitable for outcome assessments in Korean-speaking patients with idiopathic scoliosis.

Abstract
Abstract
Background
In the Edoxaban Low-Dose for Elder Care Atrial Fibrillation Patients (ELDERCARE-AF) trial, low-dose edoxaban (15mg once daily) showed better efficacy for stroke prevention and positive net clinical benefit compared to placebo in very elderly and high bleeding risk patients with atrial fibrillation (AF) who often excluded from oral anticoagulation (OAC) therapy. However, there are limited data to generalize the ELDERCARE-AF results into daily practice.
Purpose
To investigate the optimal OAC strategy for the best net clinical benefit in ELDERCARE-AF-like patients.
Methods
Using the Korean nationwide claims database, we included patients with incident non-valvular AF aged 80 years or older between 2014 and 2017. Among these, patients with one or more of the following criteria were finally included in the analysis: a low creatinine clearance (15 to 30 mL/min), a history of bleeding from a critical area or organ or gastrointestinal bleeding, low body weight (≤45kg), continuous use of nonsteroidal anti-inflammatory drugs, or current use of an antiplatelet drug. The risks of ischemic stroke, major bleeding, all-cause death, and composite clinical outcome (ischemic stroke+major bleeding+all-cause death) as a measure of net clinical outcome were evaluated during follow-up. The inverse probability of treatment weighting (IPTW) method was used to balance covariates between the groups.
Results
A total of 23,858 patients were finally included (no OAC, n=16,575; warfarin, n=2390; and direct oral anticoagulants (DOACs), n=4893, respectively). Among DOAC group, 69% used low-dose including rivaroxaban 15 mg once daily, dabigatran 110 mg twice daily, apixaban 2.5 mg twice daily, and edoxaban 30 mg once daily and 9% used very low dose including rivaroxaban 10 mg once daily and edoxaban 15 mg once daily (Figure). Median follow-up duration was 2 years (interquartile ranges, 1 to 3 years). Baseline characteristics were well-balanced after IPTW. Compared to the no OAC group, the DOAC group was associated with a lower risk of ischemic stroke (hazard ratio [HR], 95% confidence interval [CI]: 0.81, 0.68–0.95) and all-cause death (0.90, 0.85–0.95), and a higher risk of major bleeding (1.43, 1.20–1.69) (Figure). Patients treated with DOAC showed a lower risk of composite clinical outcome compared to those without OAC treatment (0.93, 0.88–0.98). Warfarin treatment did not reduce the risk of ischemic stroke (1.03, 0.85–1.23) and all-cause death (1.05, 0.99–1.12), but increased the risk of major bleeding (1.60, 1.32–1.92) and the composite clinical outcome (1.08, 1.02–1.15) compared to no OAC group.
Conclusion
In very elderly patients with non-valvular AF who had one or more frail components, DOACs which were currently prescribed in usual clinical practice showed better effectiveness and positive net clinical benefit compared to no OAC treatment. Compared to the latter, warfarin did not show benefit and possible harm.

Abstract
Abstract
Background
Selective sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown cardiovascular protection independently of glycemic control. Angiotensin II (Ang II) and H2O2 induced the expression of SGLT1 and 2 in cultured endothelial cells and isolated arteries to promote oxidative stress and endothelial dysfunction. However, the expression level and role of SGLT1 and 2 in human arteries remain poorly studied.
Purpose
This study examined the expression level of SGLT1 and 2 in the human internal mammary artery (IMA) obtained from bypass surgery patients, and, if so, determined the underlying mechanism and function.
Methods
IMAs were obtained from 40 bypass surgery patients (age 45 to 82). The expression level of target factors was assessed by Western blot analysis, immunofluorescence staining and RT-PCR, and the level of oxidative stress using dihydroethidium staining. Human kidney was used as a control tissue known to express SGLT1 and 2. Porcine coronary artery endothelial cells (CAEC) were cultured and studied at passage 1.
Results
Western blot analysis of 40 IMA samples indicated a high level of both SGLT1 and 2 in 16 and 17 IMAs, an intermediate level in 8 and 6 IMAs, and a low one in 16 and 17 IMAs, respectively. Immunofluorescence staining of IMA sections indicated that SGLT1 and 2 immunofluorescence signals were observed predominantly in the intima thickening and the media. The expression levels of SGLT1 and 2 were associated with p-p65 NF-kB signals but not angiotensin-converting enzyme (ACE), AT1R, MCP-1, VCAM-1. IMAs with a high expression level of SGLT1 and 2 had a high level of ROS throughout the arterial wall including the intima thickening and endothelium, which was inhibited by the antioxidant N-acetylcysteine, the ACE inhibitor perindoprilat, the AT1R antagonist losartan, and also by the dual SGLT1 and 2 inhibitor sotagliflozin and the selective SGLT2 inhibitor empagliflozin. Pro-inflammatory cytokines mRNA levels of IL-1β, TNF-α and IL-6 were detected in IMAs. Exposure of CAEC to either TNF-α, IL-1β or IL-6 caused a concentration-dependent upregulation of SGLT1 and 2.
Conclusion
The present findings indicate that SGLT1 and 2 expression is observed in some but not all IMAs of bypass surgery patients predominantly in the media, the intima thickening and the endothelium. High expression levels of SGLT1 and 2 are associated with NF-kB activation and oxidative stress that is prevented by a selective SGLT2 inhibitor and by a dual SGLT1/2 inhibitor. Since pro-inflammatory cytokines triggered SGLT1 and 2 expression in endothelial cells, the inflammatory burden of patients appears to be an important trigger regulating SGLT1/2 expression and the subsequent pro-oxidant response prompting pro-inflammatory and pro-thrombotic responses.

Abstract
Abstract
Background
Various physiology-based indices have been proposed to predict adverse clinical events in patients with coronary artery disease (CAD), such as the sum of three vessel-fractional flow reserve (3v-FFR), and the functional SYNTAX score (fSS). However, these values could not fully reflect the anatomical factors, which remains as a barrier for clinical application of these indices.
Purpose
To propose a novel index which can reflect both anatomical and physiologic features in CAD patients, and evaluate the additional predictive value for cardiovascular adverse events compared to previous indices.
Methods
For an index which can reflect both anatomical and physiologic features, we proposed the FFR adjusted SYNTAX score (FaSs). The FaSs is calculated by adding the product of the SYNTAX score and `1-FFR', for all three major coronary arteries. Among the 1136 patients who enrolled at 3V FFR-FRIENDS study, we investigated 866 patients, after excluding those who had missing variables. The 3v-FFR, fSS and FaSs were calculated, derived from the baseline FFR and SYNTAX score. Patients were divided into two groups according to the median value of each index. The primary endpoint was major adverse cardiac events (MACE, a composite of cardiac death, myocardial infarction and ischemia-driven revascularization) at 2 years follow-up.
Results
Among the total population, MACE occurred in 35 (4.04%) patients. Using the median value in a multivariable COX regression model, only FaSs was associated with an increased risk of MACE, (Hazard Ratio [HR] 5.256, 95% confidence interval [CI] 2.014–13.720), while 3v-FFR (HR 1.383, 95% CI 0.685–2.790) and fSS (HR 1.640, 95% CI 0.830–3.243) were not significantly associated with a higher risk of MACE. This was also observed in the Kaplan Meier survival curve analysis (log-rank p value: p<0.001 for FaSs, 0.153 for 3v-FFR, and 0.061 for fSS; Figure 1) The sensitivity and specificity of the FaSs was 85.7% and 51.6%, which was higher compared to the 3v-FFR (62.9% and 49.3%, respectively) and fSS (57.1% and 58.5%, respectively). When these indices were combined with clinical risk factors (age, sex, hypertension, diabetes, hyperlipidemia, chronic renal failure, LVEF<40%), FaSs was superior compared with 3v-FFR and fSS assessed in regards of the predictive accuracy for MACE (Figure 2).
Conclusion
The FaSs, which is a novel index calculated by a formula using the SYNTAX score and FFR, showed a superior predictive value for MACE compared to previous indices. Our results confirm the importance of considering both anatomical and physiologic parameters in evaluating the patient's risk for cardiovascular adverse outcomes.

Abstract
Objectives The purpose of the present study was to examine associations between life stress and incarceration history in relation to sexual health risk practices among a sample of cisgender Black gay, bisexual and other men who have sex with men (MSM) in the Deep South. METHODS Using data from a sample of 355 cisgender Black MSM in Mississippi and Georgia, multivariable logistic regression analyses were conducted to examine associations between life stress and sexual risk practices. In addition, we assessed whether stress may interact with experiences of incarceration to influence sexual health risk practices. RESULTS After controlling for sociodemographic characteristics, stress was associated with some sexual risk practices (e.g. alcohol and drug use during sex and group sex). Further, when an interaction with incarceration was assessed, among participants who had been incarcerated, high compared with low levels of stress were associated with alcohol use during sex (adjusted odds ratio (aOR) 4.59, 95% confidence interval (CI) 2.11-9.99, P < 0.001), drug use during sex (aOR 3.92, 95% CI 1.79-8.60, P < 0.001), condomless sex with casual partners (aOR 2.83, 95% CI 1.31-6.12, P < 0.001), having six or more casual partners (aOR 2.77, 95% CI 1.09-7.06, P = 0.02) and participating in group sex (aOR 5.67, 95% CI 2.07-15.51, P < 0.001). Stress and incarceration produced a dose-response effect for each association; similar associations with stress were not observed among men who had not been incarcerated. CONCLUSIONS Among people with experiences of incarceration, there are several possible ways our findings could be applied practically, including through safer sex and stress management interventions designed specifically for Black MSM following their release.

Abstract
BACKGROUND AND GOAL OF THE STUDY The goal of the study was to compare the incidence of complications, technical difficulty of intubation and physiologic pre-intubation status between the first intubation and reintubation performed on the same patient in an ICU. MATERIALS AND METHODS The study was approved by the ethics committee of Galicia (Santiago-Lugo, code No. 2015-012). Due to the observational, noninterventional, and noninvasive design of this study, the need for written consent was waived by the ethics committee of Galicia. Patients requiring tracheal intubation and reintubation in the ICU were included in this prospective observational study. Main endpoint was to compare the incidence of complications, physiologic pre-intubation status, and the rate of technical difficulty of intubation between the first intubation and reintubation performed on the same patient in an ICU. RESULTS AND DISCUSSION 504 patients were intubated in our ICU during the study period, and 82 (16%) required reintubation. There was no difference between the first intubation and reintubation regarding number of total complication (35% vs 33%; P = ,86), hypotension (24% vs 24%; P = 1), hypoxia (26% vs 26%; P = 1), esophageal intubation (1% vs 1%; P = 1), and bronchoaspiration (2% vs 1%; P = ,86). Physiologic pre-intubation status and technical difficulty of intubation did not differ between the first intubation and reintubation. CONCLUSIONS In our ICU patients requiring tracheal reintubation, incidence of complications, physiologic pre-intubation status, and technical difficulty of intubation did not differ between the first intubation and reintubation.

Background
In Asian patients with atrial fibrillation (AF), off-label underdosed prescriptions of direct oral anticoagulants (DOACs) are common
Purpose
We aimed to compare the effectiveness and safety of off-label underdosed apixaban with on-label standard dose apixaban in Asian patients with AF.
Methods
Using the Korean nationwide claims database, we identified patients who prescribed apixaban and did not fulfill the dose reduction criteria of apixaban between January 2015 and December 2017. Multivariable Cox hazard regression model was performed and hazard ratios (HRs) for ischemic stroke, major bleeding (MB), all-cause death, and the composite clinical outcome were analyzed.
Results
Compared to patients prescribed on-label standard dose apixaban (n = 4,194), patients prescribed off-label underdosed apixaban (n = 2,890) were associated with higher risks of ischemic stroke (adjusted HR [aHR] 1.38, 95% confidence interval [CI] 1.06-1.81), all-cause death (aHR 1.19, 95% CI 1.01-1.39) and the composite clinical outcome (aHR 1.17, 95% CI 1.03-1.34), but with no significant differences in MB between the two groups (Figure). In patients without any dose reduction criteria, off-label underdosed apixaban use was associated with a significantly higher risk of ischemic stroke than on-label standard dose apixaban use (aHR 1.85, 95% 1.25-2.73); however, in patients who had single dose reduction criteria (age ≥80 years, serum creatinine ≥1.5mg/dL, or bodyweight ≤60 kg), off-label underdosed apixaban use did not show a significant overall benefit in the composite clinical outcome compared with on-label standard dose apixaban, but was associated with a higher risk of all-cause death (aHR 1.32, 95% CI 1.07-1.64).
Conclusion
Off-label underdosed apixaban use was associated with higher risks of ischemic stroke, all-cause death, and composite clinical outcome and comparable risk of MB compared with on-label standard dose apixaban use. Label-adherence of apixaban dosing should be emphasized to achieve the best clinical outcome for Asian patients with non-valvular AF, especially in those without any dose reduction criteria.

Abstract
Stilbenes, including resveratrol and viniferins, a small family of polyphenols, are considered the most important phytoalexin group in Vitis species. In a previous study, we found that co-treatment of methyl jasmonate (MJ) and stevioside (STE) resulted in enhanced extracellular production of viniferins in grapevine cell suspension cultures. Thus, to further understand the mechanisms of viniferin production in grapevine cell cultures, we performed transcriptome analysis and isolated seven candidates of grapevine peroxidase genes (VlAPX6, VlGPX5, VlPRX13, VlPRX21, VlPRX35, VlPRX40, and VlPRX50). Bioconversion of trans-resveratrol to δ-viniferin was examined using crude protein extracts isolated from agroinfiltration-based transient expression of VlPRXs in Nicotiana benthamiana. In addition, we found that crude protein extracts from VlPRX21-, VlPRX35-, and VlPRX40-overexpressing (OX) transgenic Arabidopsis plants led to the conversion of trans-resveratrol to δ-viniferin. We found that in vitro experiments with crude protein extracts from VlPRX21-OX and VlPRX35-OX Arabidopsis plants catalyzed the dimerization of trans-resveratrol to δ-viniferin. Our results suggest that VlPRX21 and VlPRX35 encode functional grapevine class III peroxidases and catalyze the oxidative dimerization of trans-resveratrol to form δ-viniferin in grapevine.

Abstract
CONTEXT The prevalence of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVDs) is increasing in Asia and several countries are adopting preventive policies to reduce consumption of sugar-sweetened beverages (SSBs). However, evidence on the relation between SSB consumption and cardiometabolic health in Asian populations has not been summarized. OBJECTIVE In this systematic review, the associations between consumption of SSBs and cardiometabolic outcomes, including obesity, T2DM, and CVD, are examined in Asian populations. DATA SOURCES The PubMed, Scopus, and Web of Science databases, and gray literature were searched up to October, 2020 to identify relevant articles. DATA EXTRACTION Two investigators independently extracted data from included studies. DATA ANALYSIS When sufficient studies were available, a random-effects meta-analysis was used to calculate the pooled estimates (expressed as risk ratio [RR] and 95% confidence interval [CI]). Heterogeneity was tested and quantified using the Cochrane Q test and I2 statistic, respectively. RESULTS Of the 17 studies included, 8 provided results about measures of adiposity (3 on weight change, 4 on body mass index (BMI), 2 on percent body fat, and 1 on abdominal obesity), 6 reported results about T2DM, and 3 reported on different CVD outcomes. High SSB consumption was significantly associated with greater weight gain and with a higher risk of selected CVD outcomes as compared with low consumption. In the meta-analysis, high SSB consumption was associated with greater T2DM risk before (RR, 1.51; 95%CI, 1.15-1.98 for highest vs lowest category; I2 = 76%) and after (RR, 1.38; 95%CI, 1.09-1.73; I2 = 56%) adjustment for BMI. CONCLUSIONS These findings suggest that high SSB consumption is directly associated with weight gain, risk of T2DM, and, possibly, selected CVD outcomes in Asian populations. Public health strategies to reduce SSB consumption in Asian countries are warranted. SYSTEMATIC REVIEW REGISTRATION PROSPERO registration no. CRD42019129456.Keywords: adiposity. cardiovascular disease, Asia, sugar-sweetened beverages, type 2 diabetes.

Abstract
AIMS For the effective production of 146S particles, which determines foot-and-mouth disease (FMD) vaccine efficacy, we aimed to identify the optimal medium that is easy-to-use, productive and economically affordable for the large-scale production of FMD vaccine. METHODS AND RESULTS Nine combinations of cell growth media and replacement media were tested for virus propagation. Apart from the replacement strategy, we tested a simple addition strategy involving the addition of 30% v/v of fresh medium to the total spent medium using the Cellvento BHK-200 (Vento). Unlike other tested media that produced poor yields of 146S particles when the spent media were not eliminated, Vento exhibited high productivity with the 30% addition strategy. CONCLUSIONS Considering its lower price and media consumption compared to those of other media that require media replacement, the 30% addition strategy of Vento is highly effective. Furthermore, owing to its simple application strategy, it makes the scale-up process easy and helps in saving the time and labour involved in spent media removal. SIGNIFICANCE AND IMPACT OF THE STUDY Through the first comparative assessment of commercial media for the 146S particle recovery, this study suggests the best practical medium for the industrial-scale production of FMD vaccines.

Abstract
BACKGROUND Executive function (EF) difficulties characterise a number of psychiatric conditions and EF impairment may be a predisposing factor and/or consequence of anxiety and stress. The aim of the study was to examine EF factors in a mixed clinical cohort (Autism Spectrum Disorder and Social Anxiety Disorder) characterised by social impairment and investigate the influence of trait anxiety and state-based depression, anxiety and stress. METHODS In Study 1, a factor analysis identified EF and non-EF latent factor structures (N=205). In Study 2, (N=137) multiple regression analyses investigated the association between trait anxiety and state based depression, anxiety and stress, on EF and non-EF cognitive domains and on the two composite indices of the Behavioural Rating Inventory of Executive Function (BRIEF). RESULTS Trait anxiety was associated with better performance on neuropsychological measures of EF while state-based stress was associated with lower EF performance. A dissociation was observed between trait anxiety and state stress on the two behavioural indices of the BRIEF. Depression, anxiety and stress did not predict performance on non-EF cognitive domains. LIMITATIONS The cross-sectional design precludes cause-effect conclusions, further only self-report measures of affect were utilised and our performance measures of EF did not include a working memory test. CONCLUSIONS The results demonstrate that trait anxiety and state-based stress influence EF processes across disorders with social impairment. The transdiagnostic efficacy of this finding can facilitate remediation strategies, it may also contribute to individuals with Autism Spectrum Disorder gaining better access to mental health services.

Abstract
BACKGROUND Jordan, a Middle Eastern country, declared a state of national emergency due to COVID-19 and a strict nationwide lockdown on 17 March 2020, banning all travel and movement around the country, potentially impacting mental health. This study sought to investigate the association between mental health (eg, anxiety and depressive symptoms) and sleep health among a sample of Jordanians living through a state of COVID-19-induced nationwide lockdown. METHODS Using Facebook, participants (n=1240) in Jordan in March 2020 were recruited and direct to a web-based survey measuring anxiety (items from General Anxiety Disorder 7-item (GAD-7) scale instrument), depressive symptoms (items from Center for Epidemiologic Studies Depression Scale), sleep health (items from the Pittsburgh Sleep Quality Index) and sociodemographic. A modified Poisson regression model with robust error variance. Adjusted prevalence ratios (aPRs) and 95% CIs were estimated to examine how anxiety and depressive symptoms may affect different dimensions of sleep health: (1) poor sleep quality, (2) short sleep duration, (3) encountering sleep problems. RESULTS The majority of participants reported having experienced mild (33.8%), moderate (12.9%) or severe (6.3%) levels of anxiety during lockdown, and nearly half of respondents reported depressive symptoms during lockdown. Similarly, over 60% of participants reported having experienced at least one sleep problem in the last week, and nearly half reported having had short sleep duration. Importantly, anxiety was associated with poor sleep health outcomes. For example, corresponding to the dose-response relationship between anxiety and sleep health outcomes, those reporting severe anxiety were the most likely to experience poor sleep quality (aPR =8.95; 95% CI=6.12 to 13.08), short sleep duration (aPR =2.23; 95% CI=1.91 to 2.61) and at least one problem sleep problem (aPR=1.73; 95% CI=1.54 to 1.95). Moreover, depressive symptoms were also associated with poor sleep health outcomes. As compared with scoring in the first quartile, scoring fourth quartile was associated with poor sleep quality (aPR=11.82; 95% CI=6.64 to 21.04), short sleep duration (aPR=1.87; 95% CI=1.58 to 2.22), and experiencing at least one sleep problem (aPR=1.90; 95% CI=1.66 to 2.18). CONCLUSIONS Increased levels of anxiety and depressive symptoms can negatively influence sleep health among a sample of Jordanian adults living in a state of COVID-19-induced nationwide lockdown.

Abstract
BACKGROUND Adjuvant chemotherapy and chemoradiotherapy are some of the standards of care for gastric cancer (GC). The Adjuvant chemoRadioTherapy In Stomach Tumors (ARTIST) 2 trial compares two adjuvant chemotherapy regimens and chemoradiotherapy in patients with D2-resected, stage II or III, node-positive GC. PATIENTS AND METHODS The ARTIST 2 compared, in a 1:1:1 ratio, three adjuvant regimens: oral S-1 (40-60 mg twice daily 4 weeks on/2 weeks off) for 1 year, S-1 (2 weeks on/1 week off) plus oxaliplatin 130 mg/m2 every 3 weeks (SOX) for 6 months, and SOX plus chemoradiotherapy 45 Gy (SOXRT). Randomization was stratified according to surgery type (total or subtotal gastrectomy), pathologic stage (II or III), and Lauren histologic classification (diffuse or intestinal/mixed). The primary endpoint was disease-free survival (DFS) at 3 years; a reduction of 33% in the hazard ratio (HR) for DFS with SOX or SOXRT, when compared with S-1, was considered clinically meaningful. The trial is registered at clinicaltrials.gov (NCT0176146). RESULTS A total of 546 patients were recruited between February 2013 and January 2018 with 182, 181, and 183 patients in the S-1, SOX, and SOXRT arms, respectively. Median follow-up period was 47 months, with 178 DFS events observed. Estimated 3-year DFS rates were 64.8%, 74.3%, and 72.8% in the S-1, SOX, and SOXRT arms, respectively. HR for DFS in the control arm (S-1) was shorter than that in the SOX and SOXRT arms: S-1 versus SOX, 0.692 (P = 0.042) and S-1 versus SOXRT, 0.724 (P = 0.074). No difference in DFS was found between SOX and SOXRT (HR 0.971; P = 0.879). Adverse events were as anticipated in each arm, and were generally well-tolerated and manageable. CONCLUSIONS In patients with curatively D2-resected, stage II/III, node-positive GC, adjuvant SOX or SOXRT was effective in prolonging DFS, when compared with S-1 monotherapy. The addition of radiotherapy to SOX did not significantly reduce the rate of recurrence after D2 gastrectomy.

Abstract
Hepatic fibrogenesis is characterized by activation of hepatic stellate cells (HSCs) and accumulation of extracellular matrix (ECM). The impact of ECM on TGF-β-mediated fibrogenic signaling pathway in HSCs has remained obscure. We studied the role of non-receptor tyrosine kinase focal adhesion kinase (FAK) family members in TGF-β-signaling in HSCs. We used a CCl4-induced liver fibrosis mice model to evaluate the effect of FAK family kinase inhibitors on liver fibrosis. RT-PCR and Western blot were used to measure the expression of its target genes; α-SMA, collagen, Nox4, TGF-β1, Smad7, and CTGF. Pharmacological inhibitors, siRNA-mediated knock-down, and plasmid-based overexpression were adopted to modulate the function and the expression level of proteins. Association of PYK2 activation with liver fibrosis was confirmed in liver samples from CCl4-treated mice and patients with significant fibrosis or cirrhosis. TGF-β treatment up-regulated expression of α-SMA, type I collagen, NOX4, CTGF, TGF-β1, and Smad7 in LX-2 cells. Inhibition of FAK family members suppressed TGF-β-mediated fibrogenic signaling. SiRNA experiments demonstrated that TGF-β1 and Smad7 were upregulated via Smad-dependent pathway through FAK activation. In addition, CTGF induction was Smad-independent and PYK2-dependent. Furthermore, RhoA activation was essential for TGF-β-mediated CTGF induction, evidenced by using ROCK inhibitor and dominant negative RhoA expression. We identified that TGF-β1-induced activation of PYK2-Src-RhoA triad leads to YAP/TAZ activation for CTGF induction in liver fibrosis. These findings provide new insights into the role of focal adhesion molecules in liver fibrogenesis, and targeting PYK2 may be an attractive target for developing novel therapeutic strategies for the treatment of liver fibrosis.

Abstract
AIM The main aim of this study was to compare the long-term outcome of a conventional colorectal endoscopic submucosal dissection (ESD) in which submucosal dissection was continued throughout until the completion of resection (ESD-T) to hybrid endoscopic submucosal dissection (ESD-H) in the colorectum. METHOD Medical records of 836 colorectal neoplasia patients treated by ESD-T or ESD-H were reviewed. ESD-H was defined as colorectal ESD with additional snaring in the final stage of the procedure. Primary outcomes were the overall and metastatic recurrence rates. Secondary outcomes were short-term outcomes such as the en bloc resection rate, procedure time and adverse events. RESULTS The overall recurrence rate was higher in the ESD-H than in the ESD-T group (5.7% vs 0.7%, P = 0.001). The metastatic recurrence rate showed no significant difference between these groups (1.4% vs 1.4%, P = 1.000). Multivariate analysis revealed that a failed en bloc resection (hazard ratio 24.097; 95% CI 5.446-106.237; P < 0.001) and larger tumour size (hazard ratio 1.042; 95% CI 1.014-1.070; P = 0.003) were independently associated with overall recurrence. The ESD-H group showed a lower en bloc resection rate (56.8% vs 96.5%, P < 0.001), shorter procedure time (45.6 vs 54.3 min, P < 0.001) and higher perforation rate (10.3% vs 6.0%, P = 0.029). CONCLUSION Although long-term outcomes in terms of overall recurrence are inferior following ESD-H, a failed en bloc resection and large tumour size are the only independent risk factors for recurrence. Further investigations are warranted to improve the long-term outcomes of ESD-H.

Abstract
OBJECTIVE It remains unclear whether ethnicity has an impact on obesity independent of socioeconomic status (SES) and environmental factors. Singapore provides a unique opportunity to address this issue because three major Asian ethnic groups are represented, and government policies prevent ethnic segregation. Therefore this study examined associations between ethnicity, SES, and obesity within neighborhoods in Singapore. METHODS Cross-sectional data from 29,819 participants of the Singapore Multiethnic Cohort who were aged 21 to 75 years and of Chinese, Malay, and Indian ethnicity were used. Obesity was defined using Asian criteria. Multilevel models used obesity as the dependent variable and age, marital status, ethnicity, education level, income, and neighborhood SES as independent variables. RESULTS Education level was more strongly inversely associated with obesity than income level or neighborhood SES. The association between ethnicity and obesity was not substantially explained by measures of individual and neighborhood SES. In females, the fully adjusted odds ratio of obesity was 5.01 for Malay ethnicity and 4.81 for Indian ethnicity as compared with Chinese ethnicity. In males, these odds ratios were 2.61 and 2.07, respectively. CONCLUSIONS Ethnicity was strongly associated with obesity independent of SES and neighborhood environment. More research on sociocultural factors contributing to ethnic differences in obesity is warranted.

Abstract
AIM To investigate the image quality and radiation dose of ultralow-dose (ULD) and low-dose (LD) lower-extremity computed tomography (CT) angiography (LE-CTA) using the advanced modelled iterative reconstruction (ADMIRE) algorithm to detect peripheral arterial disease (PAD) in comparison with standard-dose (SD) CT. MATERIALS AND METHODS One hundred and seven consecutive patients were examined using LE-CTA at 70 kVp and a dual-source scanner to achieve three image sets using 30% (ULD), 70% (LD), and 100% (SD) tube loads. Qualitative analysis was conducted by examining the three image sets for overall quality. The image quality of arterial segments was analysed by two independent readers. In addition, the CT dose index (CTDIvol) was measured in the three image sets. RESULTS The mean overall quality scores were 3.4±0.6 for ULD CT, 3.9±0.3 for LD CT, and 3.9±0.2 for SD CT. Both readers scored the arterial segments as 2-4 (adequate-excellent) in the three image sets. In addition, 89.4% (93/104) and 54.8% (57/104) segments of PAD with calcified plaques were scored 4 between SD and LD CT and between SD and ULD CT, respectively, and 45.2% (47/104) segments had a lower score by one point in ULD CT compared with SD CT. The mean CTDIvol was 4.1±1.1 mGy for SD CT, 2.9±0.8 mGy for LD CT, and 1.2±0.3 mGy for ULD CT. CONCLUSIONS LD/ULD CT at 70 kVp using ADMIRE reconstruction enables a reduction in the radiation dose while enabling adequate evaluation or follow-up of PAD based on LE-CTA.

Abstract
AIM To develop a laboratory-based tooth model of simulated blood flow in teeth and evaluate it using ultrasound Doppler flowmetry (UDF). METHODOLOGY A laboratory-based tooth model for UDF was created based on a microfluidic experimental model proposed by Kim & Park (2016 a,b). Twenty-one maxillary or mandibular anterior human teeth within 1 month of extraction were used. Four holes were made in each tooth to fit 1.6-mm diameter polytetrafluoroethylene (PTFE) tubes: at the apical foramen, palatal surface in the centre of the crown, palatal surface apical to the cementoenamel junction (CEJ) and the root centre. Fluid mimicking pulsating blood was pumped (pressure range: 0-200 mbar, flow rate range: 0-80 μL min-1 ) into the apical foramen via the PTFE tubes, which exited the tooth through the palatal surface in the centre of the crown (control group), palatal surface below the CEJ (group 1) and the palatal surface at the mid-root level (group 2). An UDF transducer of 20 MHz was placed at a 60° angle to the labial surface of tooth and was used to measure the fluid flow velocity (Vs, Vas, Vm, Vam, Vd, Vad and Vakd). The flow velocity of the different groups was compared using the Wilcoxon signed-rank test, with a 95% confidence level. RESULTS UDF facilitated the detection of the simulated pulpal blood flow in the control group and group 1, but not in group 2. The mean and standard deviations of Vas, Vam and Vakd were 0.921 ± 0.394, 0.479 ± 0.208 and 0.396 ± 0.220 cm s-1 , respectively, in the control group, and 0.865 ± 0.368, 0.424 ± 0.215 and 0.487 ± 0.279 cm s-1 , respectively, in group 1. The pulpal blood flow values of the control group and group 1 were not significantly different (p > 0.05). CONCLUSIONS This laboratory study revealed that ultrasound Doppler flowmetry enabled the detection of simulated blood flow below the level of the CEJ but not at the mid-root level.

Abstract
Background Most hookah use studies have not included racial and ethnic minorities which limits our understanding of its use among these growing populations. This study aimed to investigate the individual characteristics of hookah use patterns and associated risk behaviors among an ethnically diverse sample of college students. Methods A cross-sectional survey of 2460 students (aged 18–25) was conducted in 2015, and data was analyzed in 2017. Descriptive statistics were used to present the sociodemographic characteristics, hookah use-related behavior, and binge drinking and marijuana use according to the current hookah use group, including never, exclusive, dual/poly hookah use. Multivariate logistic regression was conducted to examine how hookah related behavior and other risk behaviors varied by sociodemographics and hookah use patterns. Results Among current hookah users (n = 312), 70% were exclusive hookah users and 30% were dual/poly hookah users. There were no statistically significant differences in sociodemographic characteristics except for race/ethnicity (p < 0.05). Almost half (44%) of the exclusive hookah users reported having at least five friends who also used hookah, compared to 30% in the dual/poly use group. Exclusive users were less likely to report past year binge drinking (17%) and past year marijuana use (25%) compared to those in the dual/poly use group (44 and 48% respectively); p < 0.001. Conclusions The socialization aspects of hookah smoking seem to be associated with its use patterns. Our study calls for multicomponent interventions designed to target poly tobacco use as well as other substance use that appears to be relatively common among hookah users.

Abstract
Tomentosin, a sesquiterpene lactone, is known to possess various biological activities. However, its anticarcinogenic activity against human hepatocellular carcinoma (HCC) cells has not been investigated in detail. Thus, this study aimed to elucidate the cytotoxic mechanism of tomentosin in human HCC cell lines HepG2 and Huh7. WST-1, cell counting, and colony formation assay results showed that treatment with tomentosin decreased the viability and suppressed the proliferation rate of HepG2 and Huh7 cells in a dose- and time-dependent manner. Cell cycle analysis revealed increased population of cells at the SubG1 and G2/M stage, and decreased population of cells at the G0/1 stage in HepG2 and Huh7 cells treated with tomentosin. Annexin V/propidium iodide double staining and TUNEL assay results showed increased apoptotic cell population and DNA fragmentation in HepG2 and Huh7 cells treated with tomentosin. Western blotting analysis results showed that tomentosin treatment significantly increased the expression level of Bax, Bim (short form), cleaved PARP1, FOXO3, p53, pSer15p53, pSer20p53, pSer46p53, p21, and p27, but decreased the expression of Bcl2, caspase3, caspase7, caspase9, cyclin-dependent kinase 2 (CDK2), CDK4, CDK6, cyclinB1, cyclinD1, cyclinD2, cyclinD3, and cyclinE in a dose-dependent manner. Taken together, this study revealed that tomentosin, which acted through cell cycle arrest and apoptosis, may be a useful therapeutic option against HCC.

Abstract
AbstractWe report the high production of stilbenes, including resveratrol and viniferin, in grapevine (Vitis labruscana L.) cell cultures through elicitation with methyl jasmonate (MeJA) and stevioside (STE). Methyl-β-cyclodextrin (MeβCD) is widely used as a solubilizer for resveratrol production. For the first time, we used STE as a solubilizer for stilbene production in plant cell cultures. MeJA was most effective elicitor in activating VvSTS expression and stimulating stilbene biosynthesis in grapevine cell cultures. The maximum concentration of δ-viniferin (892.2 mg/L) production with a small amount of trans-resveratrol (12.2 mg/L) was observed in the culture medium by co-treatment of cells with MeJA and STE, whereas the highest level of trans-resveratrol (371.9 mg/L) with a slight amount of δ-viniferin (11.5 mg/L) was accumulated in the culture medium of cells treated with MeJA and MeβCD. However, neither trans-resveratrol nor δ-viniferin were significantly elevated within the cells by the applications. Notably, predominant production of δ-viniferin and trans-resveratrol was observed in shake and static flask culture medium, respectively, by co-treatment of MeJA and STE. Furthermore, stilbene compounds of resveratrol, ε-viniferin, and δ-viniferin were mainly produced in a 3-L bioreactor culture following elicitation of cells with MeJA and STE. These results provide new strategies for conditional, high-level production of resveratrol and viniferin in cell cultures by utilizing the solubilizing properties of STE or MeβCD.

Abstract
Nutrient deficiency alters growth and development of crop plants and compromises yield. Real-time non-invasive monitoring of the nutritional status of crops would allow timely applications of fertilizers to optimize for growth and yield at different times of the plant's life cycle. Here, we used Raman spectroscopy to characterize Arabidopsis and two varieties of leafy vegetable crops under nitrogen sufficient and deficient conditions. We showed that the 1046 cm-1 Raman peak serves as a specific signature of nitrogen status in planta, which can be used for early diagnosis of nitrogen deficiency in plants before onset of any visible symptoms. Our research can be applied toward crop management for sustainable and precision agriculture.

Abstract
Pterocarpans are derivatives of isoflavonoids, found in many species of the family Fabaceae. Sophora flavescens Aiton is a promising traditional Asian medicinal plant. Plant cell suspension cultures represent an excellent source for the production of valuable secondary metabolites. Herein, we found that methyl jasmonate (MJ) elicited the activation of pterocarpan biosynthetic genes in cell suspension cultures of S. flavescens and enhanced the accumulation of pterocarpans, producing mainly trifolirhizin, trifolirhizin malonate, and maackiain. MJ application stimulated the expression of structural genes (PAL, C4H, 4CL, CHS, CHR, CHI, IFS, I3’H, and IFR) of the pterocarpan biosynthetic pathway. In addition, the co-treatment of MJ and methyl-β-cyclodextrin (MeβCD) as a solubilizer exhibited a synergistic effect on the activation of the pterocarpan biosynthetic genes. The maximum level of total pterocarpan production (37.2 mg/g dry weight (DW)) was obtained on day 17 after the application of 50 μM MJ on cells. We also found that the combined treatment of cells for seven days with MJ and MeβCD synergistically induced the pterocarpan production (trifolirhizin, trifolirhizin malonate, and maackiain) in the cells (58 mg/g DW) and culture medium (222.7 mg/L). Noteworthy, the co-treatment only stimulated the elevated extracellular production of maackiain in the culture medium, indicating its extracellular secretion; however, its glycosides (trifolirhizin and trifolirhizin malonate) were not detected in any significant amounts in the culture medium. This work provides new strategies for the pterocarpan production in plant cell suspension cultures, and shows MeβCD to be an effective solubilizer for the extracellular production of maackiain in the cell cultures of S. flavescens.

Abstract
BACKGROUND As chest reconstructions in Poland syndrome are performed for patients at young ages, patients are generally concerned about conspicuous scars. Meanwhile, a robotic-assisted latissimus dorsi (LD) muscle harvest with inconspicuous scars has been performed for autologous breast reconstruction. As our experience with robotic-assisted LD flap harvest has increased over the years, we have made improvements in surgical techniques to optimize results. The purpose of this study was to introduce and identify the role of the refined robotic-assisted LD muscle flap harvest technique in autologous chest reconstruction in patients with Poland syndrome. METHODS Autologous chest reconstruction using a robotic-assisted LD muscle flap harvest was performed for 21 patients with Poland syndrome. Subjective assessments were performed to evaluate improvement in chest deformity, patient satisfaction with overall outcomes, chest symmetry, and scars. Assessments by the operator and two independent evaluating investigators were carried out with patients' photographs. The complication rates and the time for robotic surgery were also evaluated. RESULTS At the last visit, the average patient grades for improvement in chest deformity, satisfaction with overall outcomes, chest symmetry, and scars were 4.80, 4.72, 4.18, and 4.87, respectively. Assessments by the operator and two independent evaluating investigators demonstrated that improvement in chest deformity was achieved in all patients. No serious complications such as flap loss were recorded for any patient. The time for robotic surgery markedly decreased as experience accumulated. CONCLUSIONS Surgical refinements for robotic-assisted LD flap harvest might be effective and reduce operative times for patients with Poland syndrome.

Abstract
BACKGROUND Pumilio RNA-binding proteins are evolutionarily conserved throughout eukaryotes and are involved in RNA decay, transport, and translation repression in the cytoplasm. Although a majority of Pumilio proteins function in the cytoplasm, two nucleolar forms have been reported to have a function in rRNA processing in Arabidopsis. The species of the genus Chara have been known to be most closely related to land plants, as they share several characteristics with modern Embryophyta. RESULTS In this study, we identified two putative nucleolar Pumilio protein genes, namely, ChPUM2 and ChPUM3, from the transcriptome of Chara corallina. Of the two ChPUM proteins, ChPUM2 was most similar in amino acid sequence (27% identity and 45% homology) and predicted protein structure to Arabidopsis APUM23, while ChPUM3 was similar to APUM24 (35% identity and 54% homology). The transient expression of 35S:ChPUM2-RFP and 35S:ChPUM3-RFP showed nucleolar localization of fusion proteins in tobacco leaf cells, similar to the expression of 35S:APUM23-GFP and 35S:APUM24-GFP. Moreover, 35S:ChPUM2 complemented the morphological defects of the apum23 phenotypes but not those of apum24, while 35S:ChPUM3 could not complement the apum23 and apum24 mutants. Similarly, the 35S:ChPUM2/apum23 plants rescued the pre-rRNA processing defect of apum23, but 35S:ChPUM3/apum24+/- plants did not rescue that of apum24. Consistent with these complementation results, a known target RNA-binding sequence at the end of the 18S rRNA (5'-GGAAUUGACGG) for APUM23 was conserved in Arabidopsis and C. corallina, whereas a target region of ITS2 pre-rRNA for APUM24 was 156 nt longer in C. corallina than in A. thaliana. Moreover, ChPUM2 and APUM23 were predicted to have nearly identical structures, but ChPUM3 and APUM24 have different structures in the 5th C-terminal Puf RNA-binding domain, which had a longer random coil in ChPUM3 than in APUM24. CONCLUSIONS ChPUM2 of C. corallina was functional in Arabidopsis, similar to APUM23, but ChPUM3 did not substitute for APUM24 in Arabidopsis. Protein homology modeling showed high coverage between APUM23 and ChPUM2, but displayed structural differences between APUM24 and ChPUM3. Together with the protein structure of ChPUM3 itself, a short ITS2 of Arabidopsis pre-rRNA may interrupt the binding of ChPUM3 to 3'-extended 5.8S pre-rRNA.

Abstract
Background This study explored the relationships between participation in group sex and risk for HIV and other sexually transmissible infections (STIs). METHODS An anonymous online survey collected data from 580 gay and bisexual men using a mobile sex and dating application in Paris, France. Logistic regression analyses were conducted, which controlled for HIV status, HIV pre-exposure prophylaxis (PrEP) use and participants' sociodemographic characteristics. RESULTS Compared with men with no recent group sex experience, those reporting group sex in the 3 months before the survey (30.7% of the sample) were more likely to have had condomless receptive anal sex at least once in the same period [adjusted odds ratio (aOR)=1.6, 95% confidence interval (CI)=1.1-2.4, P = 0.02], condomless insertive anal sex (aOR=2.0, 95%CI: 2.4-8.7, P < 0.001) and substance use before or during sex (aOR=1.6, 95%CI: 1.1-2.3, P = 0.02). Even when controlling for condom use, men involved with group sex were more likely to be have been diagnosed with a bacterial STI in the previous year (aOR=2.1, 95%CI: 1.3-3.3, P = 0.002). CONCLUSIONS Group sex remains a useful marker of risk among gay and bisexual men, but research is needed that moves beyond individual practice in order to assess the epidemiological networks comprising group sex and the risks they pose relevant to HIV and other STIs.

Abstract
Prior research has documented the ways in which financial hardships negatively impact health, particularly mental health. However, this association between financial hardships and mental health outcomes has rarely been examined in sexual minorities. The purpose of this study was to examine associations between financial hardships and mental health burdens among a sample of gay, bisexual and other men who have sex with men (MSM) in Paris, France. Participants (n = 580) completed a cross-sectional survey advertised on a geosocial networking application. Participants responded to measures of mental health, financial hardship, and socio-demographics. Modified Poisson models were used to estimate risk ratios (RRs) and 95% confidence intervals (CI) for the associations between financial hardship and the following outcomes: 1) depressive symptoms, 2) anxiety symptoms, and 3) psychological distress. After adjusting for socio-demographics, high financial hardships were associated with depressive symptoms (aRR: 1.48, 95% CI: 1.04, 2.11) and psychological distress (aRR: 1.56, 95% CI: 1.09, 2.23). Analyses also demonstrated that stress acts as a mediating variable. These preliminary results suggest that future interventions to reduce financial hardships may have positive effects on the mental health of such a population.

Abstract
Cuprous halides, characterized by a direct wide band-gap and a good lattice matching with Si, is an intrinsic p-type I-VII compound semiconductor. It shows remarkable optoelectronic properties, including a large exciton binding energy at room temperature and a very small piezoelectric coefficient. The major obstacle to its application is the difficulty in growing a single-crystal epitaxial film of cuprous halides. We first demonstrate the single crystal epitaxy of high quality cuprous iodide (CuI) film grown on Si and sapphire substrates by molecular beam epitaxy. Enhanced photoluminescence on the order of magnitude larger than that of GaN and continuous-wave optically pumped lasing were found in MBE grown CuI film. The intrinsic p-type characteristics of CuI were confirmed using an n-AlGaN/p-CuI junction that emits blue light. The discovery will provide an alternative way towards highly efficient optoelectronic devices compatible with both Si and III-nitride technologies.

Abstract
Objective To examine the association between state-level tobacco control measures and current use estimates of both e-cigarettes and cigarettes, while accounting for socio-demographic correlates. Methods Using the 2012-2013 and 2013-2014 National Adult Tobacco Survey (NATS), we assessed prevalence estimates of US adults' e-cigarette and cigarette current use. Four state groups were created based on the combined state-specific prevalence of both products: low cigarette/e-cigarette (n = 15), high cigarette/e-cigarette (n = 16), high cigarette/low e-cigarette (n = 11), and low cigarette/high e-cigarette) (n = 9). To evaluate the implementation of state-level tobacco control measures, Tobacco Control Index (TCI) was calculated using the State of Tobacco Control annual reports for 2012 and 2013. Multinomial logistic regression models were used to examine differences among the four groups on socio-demographic factors and TCI. Low cigarette/e-cigarette group was used as the referent group. Results Current use estimates of each product varied substantially by state; current e-cigarette use was highest in Oklahoma (10.3%) and lowest in Delaware (2.7%), and current cigarette use was highest in West Virginia (26.1%), and lowest in Vermont (12.6%). Compared to low cigarette/e-cigarette, all other US-state categories had significantly lower TCI scores (high cigarette/e-cigarette: adjusted Relative Risk Ratio [aRRR] = 0.61; 95% confidence interval [CI]: 0.60-0.61, high cigarette/low e-cigarette: aRRR = 0.74; 95% CI: 0.73-0.74, and low cigarette/high e-cigarette: aRRR = 0.72; 95% CI: 0.71-073). Conclusions Enforcing existing tobacco control measures likely interacts with e-cigarette use despite being cigarette-focused. Continuing to monitor e-cigarette use is critical to establish baseline use and evaluate future e-cigarette specific federal and state-level tobacco regulatory actions while accounting for the existing tobacco control environment. Implications This study investigates state-level current use estimates of e-cigarettes and cigarettes among US adults; and their association with four existing tobacco control measures. The overall score of these measures was negatively associated with state-level current use estimates such that states with low current e-cigarette and cigarette use had the highest mean overall score. This study assesses the potential relationship between existing state-level tobacco control measures and e-cigarette use and calls for improving the enforcement of the known-to-work tobacco control measures across all US states, while developing evidence-based regulations and interventions specific to e-cigarettes within the existing US tobacco use environment.

Abstract
A 56-year-old male was referred in order to identify Fabry disease after his older brother was confirmed as Fabry disease of cardiac variant type. He had been treated with hypertrophic cardiomyopathy (HCMP) five years ago. He didn’t have a history of hypertension. Blood pressure was 118/65 mmHg and pulse rate was 75 beats per minute. Serum creatinine was 1.07 mg/dl and estimated glomerular filtration rate was 75.2 ml/min. Cardiac enzymes including CK-MB and troponin-T were normal. There was no proteinuria on urinalysis. A 12-leads electrocardiogram revealed normal sinus rhythm with severe left ventricular hypertrophy (LVH) and strain pattern. Transthoracic echocardiogram (TTE) showed diffuse severe concentric hypertrophy of the left ventricle (LV) of an average ventricular wall thickness of 17 mm with normal systolic function (left ventricular ejection fraction (LVEF), 56%). TTE also revealed left ventricular outflow tract obstruction with systolic anterior motion of mitral valve. Right ventricle (RV) was also hypertrophied (RV free wall thickness, 7mm). Also, echocardiography revealed findings of diastolic dysfunction; left atrial enlargement, mitral inflow of a pseudo-normal pattern on pulsed wave Doppler image and an increased left ventricular filling pressure on tissue Doppler image (E/e’=20). Cardiac magnetic resonance imaging (MRI) revealed diffuse LV and RV hypertrophy and preserved LV systolic function with hypokinesia of mid-septal LV wall. Delayed hyper-enhancement (DHE) was not found within entire myocardium. A coronary CT angiography was performed because of regional wall motion abnormality but did not show any significant stenoses. He was confirmed as Fabry disease with the same genetic mutation as his brother. He did not present symptoms and signs of any other organs besides only myocardial hypertrophy. He received enzyme replacement therapy (ERT) with intravenous agalsidase-beta every other week via outpatient department for 3 years. Recently, TTE was performed and showed diffuse severe concentric LVH of an average ventricular wall thickness increased to 19 mm despite regularly ERT. Focal intramural and subepicardial DHE was newly developed at LV basal lateral and septal wall on cardiac MRI. Neutralizing antibody against agalsidase -beta was not found in serum.
Fabry disease of cardiac variant type can be delayed in diagnostic aspect because of absence of typical symptoms and signs. Despite the absence of neutralizing antibody, ERT did not prevent both further myocardial hypertrophy and myocardial fibrosis in patient with advanced myocardial hypertrophy caused by delayed diagnosis of Fabry disease. Suspicion of Fabry disease through detailed history taking including family history in patients with diffuse ventricular hypertrophy on an echocardiography can lead to early diagnosis and treatment and can result in improvement in a clinical outcome.

Abstract
Background
Diastolic blood pressure has a J-curve relation with coronary heart disease and death, but it is debating whether a J-curve association exists in general population. We aimed to assess the relation of blood pressure to mortality, and whether their association is interacted with presence of high coronary artery calcium (CAC).
Methods
The KOICA registry is a retrospective, multicenter observational study designed to investigate the effectiveness and prognostic value of CAC score for primary prevention of cardiovascular disease in asymptomatic Korean adults. The association between CAC score and blood pressure was assessed. Patients were divided into 2 groups according to the baseline CACS (> 300 and ≤ 300), and all-cause mortality was assessed.
Results
The study population composed 48903 subjects with a mean age of 54 ± 9. There were 425 (0.9%) deaths during follow-up. At baseline, SBP (systolic blood pressure) more than 110 mmHg and DBP (diastolic blood pressure) more than 80 mmHg was associated with increased risk for CACS > 300. In patients with baseline CACS ≤ 300, all-cause mortality was increased in patients with SBP of 110-119 mmHg (HR 1.47, p = 0.023), 130-139 mmHg (HR 1.72, p = 0.002) and ≥ 140 mmHg (HR 1.47, p = 0.042) compared to SBP of 120-129 mmHg, whereas DBP did not predict all-cause mortality. In contrast, SBP was not associated to all-cause mortality in patients with CACS > 300, whereas DBP < 60 mmHg (HR 3.53, p =0.018) and 70-79 mmHg (HR 2.21, p = 0.042) was associated with increased risk for all-cause mortality compared to DBP of 80-89 mmHg.
Conclusion
Low DBP was associated with increased risk for all-cause mortality in subjects with high CAC score, suggesting high-risk for coronary artery disease. However, this J-curve relation was not shown in the population with low CAC score.

Associations Between Neighborhood Problems and Sexual Behaviors Among Black Men Who Have Sex with Men in the Deep South: The MARI Study. Arch Sex Behav 2020; 49:185-193.

Abstract
There is a disproportionately high HIV incidence among Black men who have sex with men (MSM) despite equal or lower levels of HIV risk behaviors compared to White MSM. Due to high levels of racial segregation in the U.S., Black MSM have an elevated likelihood of living in neighborhoods that contain psychosocial stressors, which, in turn, may increase behaviors promoting HIV infection. We examined associations between perceived neighborhood problems and sexual behaviors among Black MSM in the Deep South, a population at highest risk of HIV. Data came from the MARI Study, which included Black MSM ages 18-66 years recruited from the Jackson, MS, and Atlanta, GA, metropolitan areas (n = 377). Participants completed questions about neighborhood problems (e.g., excessive noise, heavy traffic/speeding cars and trash/litter) and sexual behaviors (e.g., condomless sex and drug use before or during sex). We used Poisson's regression model with robust standard errors to estimate the adjusted prevalence ratio (aPR; 95% confidence intervals [CI]) of neighborhood problems (coded as tertiles [tertile 1 = low neighborhood problems, tertile 2 = medium neighborhood problems, tertile 3 = high neighborhood problems] as well as continuously) with sexual behaviors, after adjustment for sociodemographic characteristics and other variables. About one-fourth of the sample reported at least one neighborhood problem, with the most common (31.6%) being no/poorly maintained sidewalks, which indicates an infrastructural problem. In multivariable models, compared to those in the lowest tertile, those reporting more neighborhood problems (tertile 2: aPR = 1.49, 95% CI = 1.04, 2.14 and tertile 3: aPR = 1.53, 95% CI = 1.05, 2.24) reported more drug use before or during sex (p for trend = .027). Neighborhood problems may promote behaviors (e.g., drug use before or during sex) conducive to HIV infection. Structural interventions could improve community infrastructure to reduce neighborhood problems (e.g., no/poorly maintained sidewalks and litter). These interventions may help to reduce HIV incidence among Black MSM in the Deep South.
