Abstract
To assess the effectiveness of culturally and linguistically tailored, peer-delivered obstructive sleep apnea education and of social support to increase adherence to physician-recommended obstructive sleep apnea evaluation among blacks. In a two-arm randomised controlled trial, we ascertained the effectiveness of peer-delivered obstructive sleep apnea education in increasing obstructive sleep apnea evaluation among 319 blacks at risk of obstructive sleep apnea (intervention = 159 and control = 160); their average age was 47 ± 12.9 years, and 41% were male. Obstructive sleep apnea risk was assessed with the Apnea Risk Evaluation System questionnaire, administered in community venues. Participants in the intervention arm received tailored obstructive sleep apnea education during a 6 month period; those in the control arm received standard sleep and healthy lifestyle information. Analysis focussed on the effectiveness of peer-delivered obstructive sleep apnea education on adherence to obstructive sleep apnea evaluation, but also considered the role of psychosocial factors. The results showed no significant differences in baseline demographic and clinical measures when contrasting participants in the study arms. The adherence rates for home-based obstructive sleep apnea evaluation in the intervention and control arms were 45.9% and 45.6%, respectively. Overall, participants in both study arms (adherers) who underwent obstructive sleep apnea evaluations were likely to experience a greater level of social support (8.2 ± 2.4 vs. 7.3 ± 2.4; p = 0.06). Moreover, adherers showed greater psychosocial scores (i.e., Dysfunctional Beliefs and Attitudes about Sleep scale, Apnea Beliefs Scale (ABS) (and Apnea Knowledge) compared with non-adherers (6.0 ± 1.8 vs. 4.9 ± 2.2; p = 0.02; 77.0 ± 7.1 vs. 73.2 ± 7.4; p = 0.04, and 6.4 ± 3.1 vs. 7.6 ± 2.4; p = 0.06, respectively). The results of the present randomised controlled trial favoured a potential role of peer-based social support and psychosocial factors, associated with obstructive sleep apnea adherence behaviour.

Abstract
Introduction Through previous studies, Chinese college students are known to be prone to alcohol consumption, which can lead to health-risk behaviors such as high blood pressure, heart disease, stroke, liver disease, and digestive problems. However, little is known about how popular social media platforms (e.g., short-form video applications) can positively impact their willingness to reduce alcohol consumption. This study was guided by the theory of optimistic bias; we investigated the direct, mediated, and moderating effects of exposure to anti-alcohol consumption short-form videos and short-form video involvement on Chinese college students' willingness to reduce their alcohol consumption. Methods The current study has an empirical cross-sectional design and employed an online survey from September 1st, 2022, to November 1st, 2022. The survey specifically targeted Chinese college students, who are the most common users of short-form video applications. The accumulated data underwent rigorous examination, including hierarchical regression, mediation, and moderation analyses, all conducted using the PROCESS macro 4.0 within SPSS version 22. Results A total of 434 participants, aged 18-24 years, were included in this study. There were mediating effects regarding Chinese college students' exposure to anti-alcohol consumption short-form videos (β = 0.35, p < 0.01, 95% CI [0.17, 0.63]) and short-form video involvement (β = 0.44, p < 0.001, 95% CI [0.20, 0.65]) on their willingness to reduce alcohol consumption via reversed optimistic bias. Moreover, perceived prevention of heavy drinking control (β = 0.05, p < 0.001, 95% CI [0.01, 0.09]) played mediating roles in the relationship between exposure to anti-alcohol consumption short-form videos and willingness to reduce alcohol consumption. Conclusion This study is one of the earliest studies to examine the intricate effects of exposure to anti-alcohol consumption short-form videos and short-form video involvement on the willingness to reduce alcohol consumption among Chinese college students. In addition, this study confirms that regardless of whether Chinese college students are conscientious, exposure to anti-alcohol consumption short-form videos did not increase their level of reversed optimistic bias. The empirical findings of this study are critical and can provide practical insights for Chinese health departments that encourage Chinese college students to minimize alcohol consumption.

Abstract
With the threat of global warming, countries worldwide have enhanced their environmental campaigns on social media to increase users' willingness to take pro-environmental actions. In this study, we examined the direct and indirect effects of exposure to environmental information on Chinese young adults' (18-25 years old) intention to participate in environmental protection actions (e.g., recycling, using public transportation, involvement in an environmental group, and participation in eco-friendly events). Data were collected from a sample of 291 Chinese young adults using a web-based survey and a thoroughly designed questionnaire. The accumulated data were analyzed using SPSS version 20. Hierarchical regression and mediation analysis were performed for testing hypotheses. The results indicated that exposure to environmental information on Chinese social media platforms (WeChat and Xiaohongshu) positively affected individuals' intention to participate in pro-environmental behavior, perceived pro-environmental behavior control, pro-environmental attitude, and fear of victimization. The indirect effect demonstrated that pro-environmental behavior control and attitude mediated the relationship between exposure to environmental information on both WeChat and Xiaohongshu and the intention to participate in pro-environmental behavior. Extending the existing literature, this study provides empirical evidence on the influence of environmental information exposure on the intention to participate in environmental protection among Chinese adults. In addition, it provides valuable insights into the mediating mechanisms involving cognitive, psychological, and emotional factors in this relationship. Policy makers should implement effective pro-environmental promotions on social media to inspire individuals to engage in environmentally friendly actions. In addition, social media managers should strictly authenticate and remove misleading environmental content.

Abstract
The thermal characteristics of crystalline and amorphous forms of a human milk oligosaccharide, 2'-fucosyllactose (2'-FL), were investigated by differential scanning calorimetry and thermogravimetric analysis, and compared with the two forms of α-lactose monohydrate. Crystalline 2'-FL (87.48% crystallinity according to X-ray diffraction) showed dehydration at 143.4 °C (close to lactose) and melting at 230.6 °C (the same as β-lactose crystal). Amorphous 2'-FL showed glass transition at 127.6 °C and crystallisation at 192.8 °C, which were much higher than the corresponding temperatures for amorphous lactose. 2'-FL showed thermal decomposition at temperatures about 10 °C higher (210-212 °C) than lactose, indicating the higher thermal stability of 2'-FL. Amorphous 2'-FL showed sharp decreases in glass transition (127.6 °C to 36.5 °C) and crystallisation (192.8 °C to 103.4 °C) temperatures with increasing water activity (aw) from 0 to 0.53, above which no glass transition or crystallisation was observed.

Abstract
This study explored the effects of Chinese college students' (20-34 years old) exposure to healthy weight information on short-form video applications on their intention to acquire healthy weight-control behaviors (reducing high-fat diet intake, accessing physical activity to control body weight, etc.). Specifically, this study investigated the direct and mediated effect on such a relationship via healthy weight awareness, the first-person effect, and perceived herd. The data were collected using a web-based survey and thoroughly tested questionnaire with a sample of 380 Chinese college students. Hierarchical regression, parallel mediation, and serial mediation analysis were applied to test the hypotheses. The results indicated that healthy weight awareness, first-person effect, and perceived herd all played mediator roles that induced the relationship between Chinese college students' exposure to healthy weight information and their intention to acquire healthy weight-control behaviors. In addition, healthy weight awareness and the first-person effect sequentially mediated this relationship.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) accounts for 8% of all major congenital anomalies. Neonates who are small for gestational age (SGA) generally have a poorer prognosis. We sought to identify risk factors and variables associated with outcomes in neonates with CDH who are SGA in comparison to neonates who are appropriate for gestational age (AGA). METHODS We used the multicenter Diaphragmatic Hernia Research & Exploration Advancing Molecular Science (DHREAMS) study to include neonates enrolled from 2005 to 2019. Chi-squared or Fisher's exact tests were used to compare categorical variables and t tests or Wilcoxon rank sum for continuous variables. Cox model analyzed time to event outcomes and logistic regression analyzed binary outcomes. RESULTS 589 neonates were examined. Ninety were SGA (15.3%). SGA patients were more likely to be female (p = 0.003), have a left sided CDH (p = 0.05), have additional congenital anomalies and be diagnosed with a genetic syndrome (p < 0.001). On initial single-variable analysis, SGA correlated with higher frequency of death prior to discharge (p < 0.001) and supplemental oxygen requirement at 28 days (p = 0.005). Twice as many SGA patients died before repair (12.2% vs 6.4%, p = 0.04). Using unadjusted Cox model, the risk of death prior to discharge among SGA patients was 1.57 times the risk for AGA patients (p = 0.029). There was no correlation between SGA and need for ECMO, pulmonary hypertensive medication at discharge or oxygen at discharge. After adjusting for confounding variables, SGA no longer correlated with mortality prior to discharge or incidence of unrepaired defects but remained significant for oxygen requirement at 28 days (p = 0.03). CONCLUSION Infants with CDH who are SGA have worse survival and poorer lung function than AGA infants. However, the outcome of SGA neonates is impacted by other factors including gestational age, genetic syndromes, and particularly congenital anomalies that contribute heavily to their poorer prognosis.

Background
Device complications, such as infection or lead dysfunction necessitating transvenous lead extraction (TLE) are continuously rising amongst patients with indwelling transvenous implantable cardioverter-defibrillator (ICD).
Objectives
Aim of this study was to characterize the procedural outcome and risk factors of patients with indwelling 1- and 2-chamber ICD undergoing TLE.
Methods
We conducted a subgroup analysis of all 1- and 2-chamber ICD patients in the GALLERY (GermAn Laser Lead Extraction RegistrY) database. Predictors for procedural failure and all-cause mortality were assessed.
Results
A total of 854 patients with ICD undergoing TLE were identified, who were younger (62.9±13.8 vs. 70.7±13.0 years; p<0.001), less likely to be female (20.8 vs. 27.1%; p<0.001) and had a higher proportion of patients with coronary artery disease (51.5 vs. 38.6%; p<0.001) and highly reduced ejection fraction (32.0 vs. 23.0%; p>0.001), when compared to non-ICD patients. Leading extraction indication was lead dysfunction (48.0 vs. 21.9%; p<0.001), followed by device-related infection (45.6 vs. 73.0%; p<0.001). There were no differences in overall procedural complications (4.3 vs. 4.3%; p=0.980), clinical success rate (97.9 vs. 97.8%; p=0.861) or procedure-related (0.8 vs. 0.5%; p=0.292) and all-cause mortality (3.4 vs. 3.7%; 0.742) between groups. Multivariate analysis revealed lead age≥10 years (OR:5.75, 95%CI:2.0-16.2; p=0.001) as independent predictor for procedural failure. Systemic infection as extraction indication (OR:9.57, 95%CI:2.2-42.4; p=0.003) and procedural complications (OR:8.0, 95%CI:2.8-23.3; p<0.001) were identified as risk factors for all-cause mortality. Predictors for systemic infection in ICD patients were atrial fibrillation (OR: 2.22, 95%CI: 1.51-3.27; p<0.001), diabetes mellitus (OR: 2.28, 95%CI: 1.59-3.25; p<0.001) and chronic kidney disease (OR: 2.0, 95%CI: 1.39-2.89; p<0.001).
Conclusions
Transvenous lead extraction is safe and efficacious in patients with 1- and 2-chamber ICD. Although lead dysfunction is the leading indication for extraction, systemic device-related infection is the main driver of all-cause mortality for ICD patients undergoing TLE.

Abstract

Type of funding sources: None.
Background
The implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) are well-established and essential therapeutic pillars for patients with heart failure and survivors of sudden cardiac death. The number of young patients receiving ICD or CRT-D has been increasing in the last decades. Understanding the key differences between the typically older ICD population and younger patients is paramount to optimized patient care.
Methods
The DEVICE registry prospectively enrolled patients undergoing ICD/CRT implantation or revision from 50 German centers between 2007–2014. Data on patient characteristics, procedural outcome, adverse events and mortality during the initial stay and follow-up was collected. All patients under the age of 45 years were identified and included into a comparative analysis with the remaining population.
Results
A total number of 4181 patients were enrolled into the registry, of which 236 patients (5.6%) were under the age of 45 years. Median age was 38.0 [31.0; 42.0] vs. 69.0 [60.0; 75.0] years, p<0.001), compared to older patients. Young patients were more likely to receive an ICD (91.5 vs. 69.4%, p<0.001), than CRT device and were less likely to suffer from non-cardiac comorbidities (20.3 vs. 67.4%, p<0.001). Coronary artery disease was less common in young patients (15.7 vs. 63.6%, p<0.001), whereas hypertrophic cardiomyopathy (11.0 vs. 2.5%, p<0.001) and primary cardiac electrical diseases (14.0 vs. 1.6%, p< 0.001) were encountered more often. Mean left-ventricular ejection fractions were 42.4±18.5 vs. 31.5±11.8%, respectively (p<0.001) with less young patients in NYHA functional class III/IV (19.5 vs. 45.3%, p<0.001). Primary symptom at presentation was chronic heart failure for older patients (19.5 vs. 34.8%, p<0.001) and survived sudden cardiac death (30.9 vs. 15.6%, p<0.001) for young patients. Thus, ICD for secondary prevention was more common in young patients (53.8 vs. 43.2%, p<0.001). There were no detectable differences in postoperative complications (3.0 vs. 4.1%, p=0.500) or in-hospital mortality (0.0 vs. 0.3%, p=1.000). Median follow-up time was 514 [398; 669] vs. 458 [391; 563] days (p=0.006). Device-associated complications requiring revision were more common in young patients (16.3 vs. 8.2%, p<0.001) and all-cause 1-year-mortality after implantation was lower (3.1 vs. 7.3%, p=0.029; HR 0.42, 95%CI: 0.19-0.94). Even though there was no difference in rates of rehospitalization between groups (32.1 vs. 32.4%, p=0.93), young patients were re-admitted more often for "cardiac" reasons (82.7 vs. 58.9%, p<0.001).
Conclusion
Rates for procedural complications and in-hospital mortality were very low and without differences between both age groups. However younger patients experienced a higher rate of postoperative complications requiring revision and had higher readmission rates for cardiac reasons, potentially due to a more active lifestyle.

Abstract
In this communication, we report on the genomic surveillance of SARS-CoV-2 using wastewater samples in Jefferson County, KY. In February 2021, we analyzed seven wastewater samples for SARS-CoV-2 genomic surveillance. Variants observed in smaller catchment areas, such as neighborhood manhole locations, were not necessarily consistent when compared to associated variant results in downstream treatment plants, suggesting catchment size or population could impact the ability to detect diversity.

Abstract
Paenibacillus is widely distributed in various environments and has the potential for use as a biotechnological agent in industrial processes. Here, we report the complete genome sequence of the marine bacterium, Paenibacillus xylanexedens PAMC 22703, which utilizes xylan. The P. xylanexedens PAMC 22703 strain was isolated from marine sediments. P. xylanexedens PAMC 22703 utilizes xylan as a carbon source to grow. The genome sequence clarified that this strain possesses genes for utilizing xylan. The complete genome sequence contained one chromosome (7,053,622 bp with 46.0% GC content) and one plasmid (44,617 bp with 44.1% C + G content). The genome harbored genes that fully deploy the xylan assimilation pathway. The complete genome sequence of P. xylanexedens PAMC 22703 would prove useful in acquiring information for its application with xylan in various industries.

Abstract
Abstract
OnBehalf
GALLERY investigators
Background
The number of cardiac implantable electronic device (CIED)-associated complications such as infection, lead dysfunction or thrombotic events is continuously rising and thus making transvenous lead extraction (TLE) an ever more needed procedure in clinical practice today. Patients with abandoned leads represent a special cohort with a potentially higher susceptibility to CIED-related infections and vascular complications. Moreover, according to literature abandoned leads seem to be associated with more procedural complications and mortality during TLE.
Aim
The aim of this study was to provide an insight on safety, procedural outcome and risk prediction on pacemaker patients with abandoned leads undergoing TLE from the largest national laser-sheath registry to date.
Methods + Results:
We conducted a retrospective analysis of the GALLERY database, which collected 2533 patients undergoing TLE in Germany between 2013 and 2017. Out of 903 pacemaker patients, who underwent TLE, 226 patients (25.0%) with abandoned leads were identified. Those patients had a higher number of leads per patient (3.2 ± 0.8 vs. 1.9 ± 0.3; ns) and longer lead dwell-times (168.0 ± 89.7 vs. 123.0 ± 69.2 months; p < 0.0001) compared to pacemaker patients without abandoned leads. There were no differences in age (71.5 vs. 72.3 years; ns), body mass index (26.5 ± 4.5 vs. 26.78 ± 4.8 kg/m2; ns) or gender distribution (69.0 vs. 66.5% male; ns). Leading indication for TLE was device infection with no difference between groups (79.7 vs 77.8 %; ns). There were no differences in terms of pacemaker dependency, length of hospitalization or comorbidities. Patients with abandoned leads had longer procedure times (112.0 ± 69.0 vs. 86.4 ± 53.0 minutes; p < 0.0001) and a higher incidence of procedural complications (6.6 vs. 3.1%; p = 0.03), but there were no differences in neither procedural and clinical success rates (96.5 vs. 97.3%; ns), nor all-cause mortality (1.33 vs. 2.66%; ns). Multivariate logistic regression revealed abandoned leads (OR 2.1, CI 1.0-4.4, p = 0.04) and female gender (OR 2.4, CI 1.2-4.9, p = 0.02) as independent predictors for procedural complications. Systemic infection (OR 5.4, CI 2.0-14.8, p = 0.001) and chronic kidney disease (OR 4.0, CI 1.5-10.7, p = 0.007) were strong predictors for all-cause mortality in patients with indwelling pacemaker. Patient age > 75 years (OR 3.9, CI 2.7-5.6, p < 0.0001) and a lead dwell-time > 10 years (OR 1.6, CI 1.1-2.2, p = 0.01) were identified as risk factors for an infectious cause for TLE.
Conclusion
Abandoned leads are frequently encountered in pacemaker patients undergoing TLE and pose an important risk factor for procedural complications. Systemic CIED-related infections are the strongest driver of mortality in this patient cohort and urgently call for further improvements in early diagnosis and prevention.

Abstract
Abstract
Introduction
Initial download and use of sleep tracking is very high, but prolonged use is very low. Poor prolonged use may be attributable to several factors such as engagement, functionality, aesthetics, information, and recommendation. We appraised these five factors in 16 consumer- and research/medical- grade digital sleep devices.
Methods
Three reviewers independently assessed 16 consumer- and medical-grade sleep digital devices using the Mobile Application Rating Scale (MARS) App quality ratings, which measures engagement (engagement, entertainment, interest, customization, interactivity, target group), functionality (functionality, performance, ease of use, navigation, gestural design), aesthetics (layout, graphics, visual appeal), information (Accuracy. Goals, Quality of information, Quantity of information, Visual information, Credibility, and Evidence base) and recommended on a Likert scale, with 1- Inadequate to 5 Excellent. Each subcategory is rated on a 1-5 Likert scale which is summed for each category: engagement (30), functionality (25), aesthetics (15), information (35) and recommended (yes or no).
Results
Devices that had the highest engagement score were Fitbit (27), Apple Watch (27), Garmin (27), and Dreem 2 headband (25.5). Apple Watch (30) had highest score; while Fitbit (13), Apple Watch (13), Garmin (13), Samsung Gear (13) had highest aesthetic score. While for information, ActiGraph (35), SOMNOwatch plus (35), CleveMed SleepView Monitor (35), CleveMed Sapphire PSG (35), SOMNOscreen plus (35), Nox T3 Sleep Monitor (35) and Nox A1 PSG System (35) had the highest ratings. The Dreem 2 headband has the potential induce prolong use among users with and without sleep disorders, based on high scores on engagement (25.5), Functionality (20.5), and Information (26.5).
Conclusion
Consumer- and research-grade digital devices that measure sleep have varying levels of engagement, functionality, aesthetics, information and recommendations to facilitate prolong use. Consumer grade devices had higher engagement, functionality and aesthetics scores, while research grade devices had higher information and recommendation scores. If consumer- and research-grade devices are to have prolonged use, standardization is needed across the five MARS components.

Abstract
Abstract
Introduction
Emotional distress (ED) is associated with poor sleep. Research shows that minority populations experience greater vulnerabilities to both ED and poor sleep. Interventions such as relaxation training and behavioral therapy address this relationship but are not always successful. Research shows that physical activity (PA) is negatively associated with ED and positively associated with sleep duration. However, it is unclear whether PA attenuates the relationship between ED and sleep, and if this relationship differs by race/ethnicity.
Methods
We analyzed data from the 2005-2015 National Health Interview Survey (NHIS), a nationally representative dataset of 416,152 participants. ED, hours of PA per day, and average sleep duration were collected. Regression models with covariates (age, sex, employment status, BMI) were used to analyze the moderation effect of PA within sleep and ED. Regression models were stratified by race/ethnicity.
Results
261,686 participants (45,926 blacks, 17.55%, and 215,760 whites, 82.45%) responded with the required variables for analysis. 63% of participants reported at least some physical activity. The results of the regression showed that a significant amount of variance in ED stemmed from sleep duration; F (7, 121088) = 1,619.72, p < 0.001. PA was found to have a significant main effect, t(121,088) = 9.01, p= <0.001. There was a significant moderation effect of PA, t(121088) =7.26, p < 0.001. Stratification showed that the moderation effect of PA was not significant among blacks t(121,088) = -1.45, p=0.149 and significant among whites b = -.08, t(101,754) = -7.82, p < 0.001.
Conclusion
The present study found support for moderation of PA in the sleep-ED relationship. However, it found that blacks do not experience the same benefits of PA in this relationship as whites. Further research should be performed to understand the connection of PA to sleep duration and ED.

Abstract
Abstract
BACKGROUND
Glioblastoma is a disease with very poor outcome. Most patients underwent maximal safe resection, especially focusing in the preservation of motor and language function. However, many caregivers were suffered from the blockage of emotion communication with patients. So the definition of maximal safe resection must include the preservation of cognition and mentalizing of patients. Here we present the experience of brain mapping in awake surgery to preserve mentalizing.
MATERIAL AND METHODS
A 61-year-old male patient with headache was transferred to our hospital because of brain tumor on CT scan checked in another hospital. On the initial MRI, multi-septate cystic tumor was shown on left medial prefrontal area. The patient was recommended the surgical resection, but patient discharged with the denial of the operation. Ten days later, patient visited our hospital again with slowness of response by the enlargement of tumor size. The tumor extensively involved left cingulum and corpus callosum at anterior part. On diffusion tensor image, tumor located at mediosuperior part of inferior fronto-occipital fasciculus (IFOF). The patient showed deficit of visual and verbal memory, generative naming ability, and phonemic generative naming ability on preoperative neuropsychological test (SNSB-II). Pyramid and palm tree test (PPTT) and ‘Reading the Mind in the Eyes’ test (RMET) were also performed to evaluate the semantic association function and mentalizing preoperatively.
RESULTS
The patient underwent awake surgery with asleep-awake-asleep technique. The tumor was resected until identification of incorrect response to PPTT or RMET on subcortical stimulation (Ojeman stimulator, 1.5mA, 60Hz, biphasic). The histopathologic diagnosis was glioblastoma. Small part of tumor was remained on cingulum, but patient was discharged without change of mentalizing.
CONCLUSION
Although the patients with glioblastomas show poor outcome, we think that it is important to consider the cognition and mentalizing of patients for emotion communication with caregivers. With awake surgery, mentalizing can be preserved in selective patients.

Abstract
BACKGROUND People discharged from in-patient psychiatric facilities have highly elevated rates of suicide, and there is increasing concern about natural mortality among the seriously mentally ill. METHOD A meta-analysis of English-language, peer-reviewed longitudinal studies of mortality among patients discharged from in-patient psychiatric facilities was conducted using papers published in MEDLINE, PsycINFO or EMBASE (from 1 January 1960 to 1 April 2018) located using the terms ((suicid*).ti AND (hospital OR discharg* OR inpatient OR in-patient OR admit*)).ab and ((mortality OR outcome* OR death*) AND (psych* OR mental*)).ti AND (admit* OR admis* OR hospital* OR inpatient* OR in-patient* OR discharg*).ab. Pooled mortality rates for aggregated natural and unnatural causes, and the specific causes of suicide, accident, homicide, vascular, neoplastic, respiratory, gastrointestinal, infectious and metabolic death were calculated using a random-effects meta-analytic model. Between-study heterogeneity was investigated using subgroup analysis and metaregression. RESULTS The pooled natural death rate of 1128 per 100 000 person-years exceeded the pooled unnatural deaths of 479 per 100 000 person-year among studies with varying periods of follow-up. Natural deaths significantly exceeded unnatural deaths among studies with a mean follow-up of longer than 2 years, and vascular deaths exceeded suicide deaths among studies with mean period of follow-up of 5 years or longer. CONCLUSION Suicide may be the largest single cause of death in the short term after discharge from in-patient psychiatric facilities but vascular disease is the major cause of mortality in the medium- and long-term.

Abstract
Fucoidans are widely used as an ingredient of dietary supplements. We investigated the immune stimulatory activities of Undaria pinnatifida ( Alariaceae) fucoidan-rich extract (UPF-RE) in vitro as well as in vivo . In vitro, the extract stimulated Raw 264.7 cells to produce significant nitric oxide (NO) metabolites and cytokines (TNF-α, IL-1α, IL-1β, and IL-6). It also induced the proliferation of primary mouse splenocytes and the secretion of IL-4, which correlated with the phosphorylation of Extracellular-signal-regulated kinase (ERK) protein. In in vivo experiments, first, 50 mg/kg of 3 different types of UPF-RE, DSU02, DSU02L (low molecular weight, <3 kDa), and DSU02H (high molecular weight, >10 kDa), were orally administered to C57BL/6 mice. After 14 days, the frequencies of CD3+, CD4+, and CD8+ T cells and NK cells from each group were analyzed. Plasma concentrations of TNF-α and IFN-γ were determined. The frequencies of CD3+ and CD4+ showed a statistically significant increase in splenocytes isolated from the DSU02 and DSU02H groups. Also, there was significant production of TNF-α and IFN-γ from the DSU02 group. Second, 3 different concentrations of DSU02 (50, 100, and 150 mg/kg) were orally administered. After 14 days, the proliferative capacity of CD3+, CD4+, and CD8+ T cells was investigated, and the plasma concentrations of IgM and total IgG were determined. Plasma concentration of IgM from the DSU02 150 mg/kg group was statistically significantly higher compared with that from the other groups. We suggest that UPF-RE could be a good candidate for a natural immune stimulator to induce innate as well as adaptive immune responses.

Abstract
OBJECTIVE To quantify the suicide rate among people discharged from non-psychiatric settings after presentations with suicidal thoughts or behaviours. METHOD Meta-analysis of studies reporting suicide deaths among people with suicidal thoughts or behaviours after discharge from emergency departments or the medical or surgical wards of general hospitals. RESULTS A total of 115 studies reported 167 cohorts and 3747 suicide deaths among 248 005 patients during 1 263 727 person-years. The pooled suicide rate postdischarge was 483 suicide deaths per 100 000 person-years (95% confidence interval (CI) 445-520, prediction interval (PI) 200-770) with high between-sample heterogeneity (I2 = 92). The suicide rate was highest in the first year postdischarge (851 per 100 000 person-years) but remained elevated in the long term. Suicide rates were elevated among samples of men (716 per 100 000 person-years) and older people (799 per 100 000 person-years) but were lower in samples of younger people (107 per 100 000 person-years) and among studies published between 2010 and 2018 (329 per 100 000 person-years). CONCLUSIONS People with suicidal thoughts or behaviours who are discharged from non-psychiatric settings have highly elevated rates of suicide despite a clinically meaningful decline in these suicide rates in recent decades.

Abstract
The effects of temperature, light, and pH on the stability of fucoxanthin in an oil-in-water emulsion were investigated with analyzing the kinetics and thermodynamics of fucoxanthin degradation. In the absence of light and air at pH 4.6, increasing the temperature from 25 to 60 °C significantly promoted fucoxanthin degradation. Total and all-trans fucoxanthin demonstrated an energetically unfavorable, non-spontaneous degradation with an Arrhenius temperature dependence. Increasing the light intensity up to 2000 lx at 25 °C and pH 4.6 caused a sharp degradation of total, all-trans, 13-cis, and 13'-cis fucoxanthin, but promoted the formation of the 9'-cis isomer. In the absence of light and air at 25 °C, decreasing the pH to 1.2 caused significant fucoxanthin degradation, whereas increasing the pH to 7.4 retarded the degradation. The property with the greatest influence on fucoxanthin stability was pH, followed by temperature and then light. Total and all-trans fucoxanthin followed first-order degradation kinetics.

Abstract
Assessment of changes in DNA methylation (DNA-m) has the potential to identify adverse environmental exposures. To examine DNA-m among a subset of participants (n = 369) in the Isle of Wight birth cohort who reported variable near resident traffic frequencies. We used self-reported frequencies of heavy vehicles passing by the homes of study subjects as a proxy measure for TRAP, which were: never, seldom, 10 per day, 1-9 per hour and >10 per hour. Methylation of cytosine-phosphate-guanine (CpG) dinucleotide sequences in the DNA was assessed from blood samples collected at age 18 years (n = 369) in the F1 generation. We conducted an epigenome wide association study to examine CpGs related to the frequency of heavy vehicles passing by subjects' homes, and employed multiple linear regression models to assess potential associations. We repeated some of these analysis in the F2 generation (n = 140). Thirty-five CpG sites were associated with heavy vehicular traffic. After adjusting for confounders, we found 23 CpGs that were more methylated, and 11 CpGs that were less methylated with increasing heavy vehicular traffic frequency among all subjects. In the F2 generation, 2 of 31 CpGs were associated with traffic frequencies and the direction of the effect was the same as in the F1 subset while differential methylation of 7 of 31 CpG sites correlated with gene expression. Our findings reveal differences in DNA-m in participants who reported higher heavy vehicular traffic frequencies when compared to participants who reported lower frequencies.

Abstract
ABSTRACT Pelvic fractures correspond to 20 to 30 % of the fractures observed in dogs. Complete fractures, especially with bone axis deviation should be surgically treated. The mechanical study of surgical techniques is of utmost importance to assess the best way of treating these injuries. This study compared, biomechanically, the use of a dynamic compression plate (DCP) and screws (group 1) or screws and polymethylmethacrylate (PMMA) (group 2) to stabilize an iliac fracture using a static test. Sixteen canine synthetic hemi-pelvises (test specimens) with a transverse iliac osteotomy were used. After fixation with implants, a load was applied to the acetabulum until failure. Group 1 maximal compressive load was 133.9±18.60 N, displacement at yield 21.10±3.59mm and stiffness 125.22±12.25N/mm. Group 2 maximal compressive load was 183.50±27.38N, displacement at yield 16.66±5.42mm and stiffness 215.68±33.34N/mm. The stabilization with polymethylmethacrylate was stronger than dynamic compression plate since it resisted a greater load in all test specimens.

Abstract
The interactions of fish gelatine (FG) with hyaluronic acid (HA) are studied in an aqueous environment at 25°C by turbidimetric titration, confocal scanning laser microscopy, dynamic light scattering, zeta potentiometry, spectrophotometry with methylene blue, and construction of state diagrams. FG forms soluble complexes with HA above a boundary pH (pHφ1), where both biopolymers are net-negatively charged, but develop insoluble complexes as liquid-state complex coacervates below pHφ1, where the two biopolymers are oppositely charged. The insoluble complexes are continuously aggregated with further acid titration, followed by immediate visible phase-separation when another boundary pH (pHp) is reached. The complex formation is mainly driven by electrostatic attractions rather than hydrogen bonding or hydrophobic interactions. The complex formation is promoted by increasing FG-to-HA weight ratio or total biopolymer concentration, or at a low ionic strength, but significantly suppressed in the presence of high ionic strength.

Abstract
This study aimed at optimizing the manufacturing conditions of a milk beverage supplemented with coffee, and monitoring its physicochemical and sensory properties during storage. Raw milk, skim milk powder, coffee extract, and emulsifiers were used to manufacture the beverage. Two sucrose fatty acid esters, F110 and F160, were identified as suitable emulsifiers. The optimum conditions for the beverage manufacture, which can satisfy two conditions at the same time, determined by response surface methodology (RSM), were 5,000 rpm primary homogenization speed and 0.207% sucrose fatty acid emulsifier addition. The particle size and zeta-potential of the beverage under the optimum condition were 190.1 nm and - 25.94±0.06 mV, respectively. In comparison study between F110 added group (GF110) and F160 added group (GF160) during storage, all samples maintained its pH around 6.6 to 6.7, and there was no significant difference (p<0.05). In addition, GF110 showed significantly higher zeta-potential than GF160 (p<0.05). The particle size of GF110 and GF160 were approximately 190.1 and 223.1 nm, respectively at initial. However, size distribution of the GF160 tended to increase during storage. Moreover, increase of the particle size in GF160 was observed in microphotographs of it during storage. The L* values gradually decreased within all groups, whereas the a* and b* values did not show significant variations (p<0.05). Compared with GF160, bitterness, floating cream, and rancid flavor were more pronounced in the GF110. Based on the result obtained from the present study, it appears that the sucrose fatty acid ester F110 is more suitable emulsifier when it comes to manufacturing this beverage than the F160, and also contributes to extending product shelf-life.

Abstract
AIM To assess the clinical utility of perfusion computed tomography (pCT) parameters in microwave ablation (MWA) of lung tumours. MATERIALS AND METHODS Patients were included who had primary or metastatic lung tumours and underwent pCT studies immediately pre- and post-MWA. Perfusion maps of the tumours were constructed using CT perfusion software (GE, Milwaukee, WI, USA). Regions of interest were drawn on sequential axial sections to extract the pCT parameters, blood volume (BV), average blood flow (BF), and mean transit time (MTT) from the entire tumour volume. Direct visualisation of perfusion maps were performed by two experienced readers blinded to outcome. Data were analysed using the Mann-Whitney test. RESULTS Thirty-one patients with 34 lung tumours had follow-up data at 12 months. The median tumour diameter was 19 mm (10-52 mm). Seven patients developed local tumour progression (LTP) at 12 months. There was no statistical difference between patients with LTP and complete treatment based on quantitative pCT parameters. Using radiologist visualisation of perfusion maps, there was moderate agreement between the two readers (kappa coefficient 0.53) with a combined 96% sensitivity, 62% specificity, 91% positive predictive value, and 80% negative predictive value. CONCLUSION Quantitative pCT parameters do not help differentiate between LTP and complete treatment, but subjective analysis of perfusion maps may be a useful assessment tool for identifying treatment adequacy potentially enabling identification of areas requiring further treatment at the time of the procedure.

Abstract
Curcuminoids from rhizomes of Curcuma longa possess various biological activities. However, low aqueous solubility and consequent poor bioavailability of curcuminoids are major limitations to their use. In this study, curcuminoids extracted from turmeric powder using stevioside (Ste), rebaudioside A (RebA), or steviol glucosides (SG) were solubilized in water. The optimum extraction condition by Ste, RebA, or SG resulted in 11.3, 9.7, or 6.7mg/ml water soluble curcuminoids. Curcuminoids solubilized in water showed 80% stability at pH from 6.0 to 10.0 after 1week of storage at 25°C. The particle sizes of curcuminoids prepared with Ste, RebA, and SG were 110.8, 95.7, and 32.7nm, respectively. The water soluble turmeric extracts prepared with Ste, RebA, and SG showed the 2,2-diphenyl-1-picrylhydrazyl radical scavenging (SC50) activities of 127.6, 105.4, and 109.8μg/ml, and the inhibition activities (IC50) against NS2B-NS3(pro) from dengue virus type IV of 14.1, 24.0 and 15.3μg/ml, respectively.

Abstract
Caesalpinia sappan is a well-distributed plant that is cultivated in Southeast Asia, Africa, and the Americas. C. sappan has been used in Asian folk medicine and its extract has been shown to have pharmacological effects. Two homoisoflavonoids, sappanol and brazilin, were isolated from C. sappan by using centrifugal partition chromatography (CPC), and tested for protective effects against retinal cell death. The isolated homoisoflavonoids produced approximately 20-fold inhibition of N-retinylidene-N-retinyl-ethanolamine (A2E) photooxidation in a dose-dependent manner. Of the 2 compounds, brazilin showed better inhibition (197.93 ± 1.59 μM of IC50). Cell viability tests and PI/Hoechst 33342 double staining method indicated that compared to the negative control, sappanol significantly attenuated H2O2-induced retinal death. The compounds significantly blunted the up-regulation of intracellular reactive oxygen species (ROS), and sappanol inhibited lipid peroxidation in a concentration-dependent manner. Thus, both compounds represent potential antioxidant treatments for retinal diseases.

Abstract
Family doctors can play an important role in preventing unplanned pregnancies. This article addresses the different contraceptives methods available in Switzerland, which are classified in 2 groups and recommends using the GATHER approach (Greet, Ask, Tell, Help, Explain, Return) to promote compliance. LARC (long acting reversible contraceptives) can be recommended to any woman who needs a reliable birth control method. These contraceptives require minimum effort for high efficiency. Further explanation regarding the use of an emergency contraception must be provided when short action contraceptives are chosen. Switzerland's abortion rate is one of the lowest in the world. Medical abortion tends to be more and more prominent. Under certain circumstances, it can be self-administered at home.
