Abstract
Background
The first wave of COVID-19 during April to July 2020 in Singapore largely affected the migrant workers living in residential dormitories. A government taskforce working with dormitory operators, employers and non-government agencies came together to deliver behavioral interventions and health care services for migrant worker as dorms were imposed movement restrictions. To fill the research gap in understanding movement restriction experiences of migrant workers, this research seeks to describe dormitory contexts and explore behavior change related to both prevention of transmission as well as healthcare seeking for COVID-19 among male migrant workers.

Methods
With social constructivism as the foundation for this study, 23 telephone interviews were conducted with Bangladeshi and Indian migrant workers. A theory-informed, data-driven conceptual framework, characterized by the “Four Ss”: Sensitization, Surveillance, Self-preservation, and Segregation was first generated and later used to frame second-stage, more in-depth, thematic analyses. An effective multipronged approach was documented, persuading migrant workers in our case-study to improve hygiene and follow some safe distancing measures, and adhere to help-seeking when symptomatic.

Results
Rapid collective adaptation was demonstrated; it was propped up by effective harnessing of infrastructure and technology. While technology and digital platforms were central to shaping Sensitization for prevention-related behaviors, interpersonal communication, especially peer-sharing, was key to normalizing and accepting healthcare delivery and norms about healthcare seeking. Interpersonal factors particularly supported successful implementation of case-detection Surveillance, stimulating Self-preserving and acceptance of rules, and was found helpful to those Segregated in recovery facilities. In contrast, encouraging prevention-related behaviors relied more heavily on multiple online-platforms, phone-based e-learning/knowledge testing, e-monitoring of behavior, as well as interpersonal exchanges.

Conclusion
Overall, the findings showed that the conception of the Four Ss helped inform intervention strategies. Anchoring these towards optimal use of technology and harnessing of interpersonal communication for prevention and promotion of healthcare seeking in the planning of future Infectious Disease outbreaks in closed institutional settings is recommended.

Abstract
Background
Influenza is associated with a decline in functional abilities among Canadian older adults, although specific impacts on daily life have not been fully explored.

Methods
In August 2019 and May 2020, we conducted surveys of Canadian adults 50-64 years and 65 years and older through an online market research platform. The survey included questions about the impact of diagnosed influenza or self-reported influenza-like-illness (ILI) on working, volunteering and caregiving.

Results
We surveyed 1006 adults in the 50-64 year age group about the 2018/19 season and 1001 about the 2019/20 season. In the 65 years and older age group, we surveyed 3548 and 3500 individuals about the 2018/19 and 2019/20 influenza seasons, respectively. In each season, nearly two-thirds of individuals 50-64 years with influenza/ILI were employed; 51.7% reported absenteeism in 2018/19 and 53.6% in 2019/20. Of the 20% of individuals 65 years and older who were employed, 47.0% of those with influenza/ILI were absent while ill in 2018/19 (39.8% in 2019/20). In 2018/2019, 29.6% of respondents 50-64 years old with influenza/ILI identified as volunteers (29.3% in 2019/2020). In both seasons, nearly half were unable to do so while ill. Of the 164 (32.7%) individuals 65 years and older who volunteered during the 2018/19 season, 80 (48.8%) did not while ill; 224 (37.3%) respondents volunteered in the 2019/20 season, and half were absent while ill. Of those 50-64 years with influenza/ILI, 97 (42.2%) and 57 (22.2%) were caregivers in 2018/19 and 2019/20, respectively. In 2018/19 and 2019/20, 40 (41.2%) and 28 (49.1%) caregivers were unable to provide care when ill, respectively. Of those with influenza/ILI in the 65 years and older age group, 123 (24.6%) and 162 (27.0%) were caregivers in 2018/19 and 2019/20, respectively. In 2018/19, 18 (14.6%) caregivers with influenza/ILI did not provide care while ill (42 [25.9%] in 2019/20).

Discussion
In Canadian older adults, influenza and ILI had notable impacts on ability to volunteer and provide care across two recent seasons. Optimization of influenza prevention in this population may yield important societal benefits.

AbstractBackgroundHallux valgus is a foot deformity that may affect gait, thus increasing the risk of falls among older people. We investigated the relationship between foot morphology, muscle strength, and physical performance.MethodsIn this study, community-dwelling older people aged ≥65 years were included. A three-dimensional footprint automatic measurement apparatus was used to measure the hallux valgus angle, arch height ratio, and heel-floor angle. Furthermore, the toe flexor strength and ankle plantar flexion strength were measured. Physical performance tests included the five-repetition sit-to-stand test, one-leg standing time, maximal step length, functional reach test, and 5-m fastest walking time (walking time). The relationship between the hallux valgus angle and foot morphology and muscle strength was examined. In addition, factors affecting physical performance testing were assessed. Two-group comparisons, correlation, and multiple comparisons were used for statistical analyses.ResultsOf the 133 women (age 77.7 ± 6.2 years), 57 had hallux valgus and 76 had no hallux valgus. There was a significant difference in the arch height ratio and heel-floor angle between women with and without hallux valgus (p < 0.001). A correlation was found between the hallux valgus angle and the heel-floor angle (r = 0.468,p < 0.001) and arch height ratio (r = − 0.337,p < 0.001), respectively. Multiple regression analysis showed that the hallux valgus angle was related to functional reach (β = − 0.162,p = 0.042), and toe flexor strength was related to five-repetition sit-to-stand (β = − 0.182,p = 0.036), maximal step length (β = 0.328,p < 0.001), and walking time (β = − 0.219,p = 0.006).ConclusionsA relationship was found between the hallux valgus angle, arch height rate, and inward inclination angle of the calcaneus. Functional reach was predicted based on the hallux valgus angle, whereas the five-repetition sit-to-stand, maximal step length, and walking time were predicted based on toe flexor strength. Hallux valgus predicted not only the forefoot but also the foot morphology and was related to physical performance. From the perspective of motor function and fall prevention, efforts should be made to better understand and prevent the onset and progression of hallux valgus.

Abstract
Background
Thrombotic popliteal artery aneurysm (PAA) with acute lower limb ischemia (ALI) is a serious disease leading to amputation. The choice of emergency procedures is not clearly defined, and the difference in therapeutic efficiency between open surgery and endovascular intervention is still unclear.

Method
We conducted a comprehensive search through PubMed, Wiley Online Library and ScienceDirect. According to the predefined inclusion and exclusion criteria, eligible articles were screened out, and all relevant data were extracted for further analysis. Our study was designed and developed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guideline. We critically assessed all included articles by Joanna Briggs Institute (JBI) Critical Appraisal Checklists and the Methodological Index for Non-Randomized Studies (MINORS).

Result
A total of 29 articles (1338 patients/1387 limbs) were included in the study. After a 1-year follow-up, the primary patency rate of the open surgery group was significantly lower than that of the endovascular intervention group (72.65 vs. 81.46%, P = 0.004), but without significant difference in the secondary patency rate (86.19 vs. 86.86%, P = 0.825). The limb salvage rate of the open surgery group was also significantly lower (83.07 vs. 98.25%, P < 0.001). After the 2-year follow-up, the primary patency rate of the open surgery group was still significantly lower (48.57 vs. 59.90%, P = 0.021).

Conclusion
The outcome of endovascular intervention was better than that of open surgery especially in the 1-year limb salvage rate and primary patency rate at the 1-year and 2-year follow-ups.

Authors: Liu Junru , Wang Xing , Fan Dongmei , Sun Lina , Zhang Weinan , Yin Fuzai , Liu Bowei 
Published: November 2022

Abstract
Background
Irisin is a novel myokine both in mice and humans, and it can also be secreted by adipose tissue and the liver in a small amounts. There are few studies on irisin and bone metabolism. The aim of this study was to assess the relationship between serum irisin levels and bone metabolism and analyze its related factors in Han young male with pre-diabetic individuals.

Methods
This cross-sectional study included 41 pre-diabetes and 45 normal glucose tolerance (NGT). Anthropometric measurements, including height, weight, waist circumference (WC), and bone mineral content (BMC), were performed. All patients underwent an oral glucose tolerance test (OGTT) after 8 h of fasting, and the levels of glucose, insulin, lipids, serum irisin and bone turnover markers were measured.

Results
The levels of serum irisin (4.4 ± 1.4 vs. 6.3 ± 1.5 µg/mL), P1NP and OC were significantly lower and CTX was significantly higher in the pre-diabetes group (P < 0.05). BMC did not differ in the two groups (P > 0.05). Serum irisin levels negatively correlated with BMI (r =-0.325), FPG (r =-0.329), TG (r =-0.339) (P < 0.05) in NGT individuals. Serum irisin levels positively correlated with P1NP (r = 0.398), OC (r = 0.351), HDL-C (r = 0.432) and negatively correlated with FPG (r = -0.725), 2 h-PG (r = -0.360) (P < 0.05) in pre-diabetic individuals. Multiple regression analysis revealed that Serum irisin (β = 9.768, P = 0.025) and WC (β = -2.355, P = 0.002) were significant independent predictors for P1NP.

Conclusion
Bone turnover markers were changed rather than bone mineral content in young men with pre-diabetes. In pre-diabetes individuals, serum irisin levels were reduced and close relationship with P1NP. Falling irisin levels may be a predictor of decreased bone formation in Han young men with pre-diabetes individuals.
Anticipatory grief and experience of providing at-home palliative care among informal caregivers of spouses in Croatia: a qualitative study
Authors: Bilić Jelena , Skokandić Lea , Puljak Livia 
Published: November 2022

AbstractBackgroundIn palliative care, caring for spouses suffering from incurable diseases can provoke a range of reactions in informal caregivers that are part of the grieving process, as well as other reactions and ways of coping with a current role, which is often challenging. Anticipatory grief occurs before death and is often present in people who face the eventual loss of a loved one or their own death. This study aimed to gain insight into the anticipatory grief of informal caregivers who are providing at-home palliative care for their ill spouse. Our research questions focus on investigating the meanings caregivers ascribe to the experience of providing palliative care and the impending loss of a spouse.MethodsA qualitative study was conducted in Zagreb, Croatia, from April to June of 2021. Eight participants took part in the study. Participants in the study were informal caregivers of a spouse suffering from an incurable, terminal disease that receives at-home palliative care. Data were collected through semi-structured face-to-face interviews. Transcripts were analyzed by interpretive phenomenological analysis.ResultsThe analysis provided several meanings that represent caregivers’ experiences and coping strategies. The caregivers bravely face the challenges of “living with an illness” by maintaining optimism, strong cohesion with their partner and a sense of joint destiny. They tend to repress their own personal needs and feelings while carrying the burden of care. Caregivers tend to stay positive and focus on living in the present by taking an active role in providing care for the ill spouse and family.ConclusionsAnticipatory grief presents emotional, cognitive, and spiritual challenges to spouse caregivers in palliative care. The contribution of this study was to gain insight into the meaning that caregivers ascribe to the experience and challenges they face while providing everyday care for their ill spouse. Confirming prior results, the experiences are generally similar to all caregivers, pointing to the need for substantial improvement in the quality of the support and help from the healthcare workers and other experts who provide palliative care and support for the patients’ family members.

Published: November 2022

Abstract
Background
The SI-CURA project (Soluzioni Innovative per la gestione del paziente e il follow up terapeutico della Colite UlceRosA) is an Italian initiative aimed at the development of artificial intelligence solutions to discriminate pathologies of different nature, including inflammatory bowel disease (IBD), namely Ulcerative Colitis (UC) and Crohn’s disease (CD), based on endoscopic imaging of patients (P) and healthy controls (N).

Methods
In this study we develop a deep learning (DL) prototype to identify disease patterns through three binary classification tasks, namely (1) discriminating positive (pathological) samples from negative (healthy) samples (P vs N); (2) discrimination between Ulcerative Colitis and Crohn’s Disease samples (UC vs CD) and, (3) discrimination between Ulcerative Colitis and negative (healthy) samples (UC vs N).

Results
The model derived from our approach achieves a high performance of Matthews correlation coefficient (MCC) > 0.9 on the test set for P versus N and UC versus N, and MCC > 0.6 on the test set for UC versus CD.

Conclusion
Our DL model effectively discriminates between pathological and negative samples, as well as between IBD subgroups, providing further evidence of its potential as a decision support tool for endoscopy-based diagnosis.
Interference in melanoma CD248 function reduces vascular mimicry and metastasis
Authors: Kuo Cheng-Hsiang , Wu Ya-Fang , Chang Bi-Ing , Hsu Chao-Kai , Lai Chao-Han , Wu Hua-Lin 
Published: November 2022

Abstract
Background
Tumor vascular mimicry is an emerging issue that affects patient survival while having no treatment at the current moment. Despite several factors implicated in vascular mimicry, little is known about stromal factors that modulate tumor microenvironment and shape malignant transformation. CD248, a type-I transmembrane protein dominantly expressed in stromal cells, mediates the interaction between cells and extracellular matrix proteins. CD248 protein expression is associated with the metastatic melanoma phenotype and promotes tumor progression in the stromal cells. This study aimed to explore the cell-autonomous effects of CD248 in melanoma vascular mimicry to aid cancer therapy development.

Methods
Loss-of-function approaches in B16F10 melanoma cells were used to study the cell-autonomous effects of CD248 on cell adhesion, migration, proliferation, and vascular mimicry. A solid-phase binding assay was performed to identify the interaction between CD248 and fibronectin. Horizontal and vertical cell migration assays were performed to analyze cell migration activity, and cell-patterned network formation on Matrigel was used to evaluate vascular mimicry activity. Recombinant CD248 (rCD248) proteins were generated, and whether rCD248 interfered with melanoma CD248 functions was evaluated in vitro. An experimental lung metastasis mouse model was used to investigate the effect of rCD248 treatment in vivo.

Results
CD248 protein expression in melanoma cells was increased by a fibroblast-conditioned medium. Knockdown of CD248 expression significantly decreased cell adhesion to fibronectin, cell migration, and vascular mimicry in melanoma cells. The lectin domain of CD248 was directly involved in the interaction between CD248 and fibronectin. Furthermore, rCD248 proteins containing its lectin domain inhibited cell adhesion to fibronectin and slowed down cell migration and vascular mimicry. Treatment with rCD248 protein could reduce pulmonary tumor burden, accompanied by a reduction in vascular mimicry in mice with melanoma lung metastasis.

Conclusion
CD248 expression in melanoma cells promotes malignant transformation by increasing the activity of cell adhesion, migration, and vascular mimicry, whereas rCD248 protein functions as a molecular decoy interfering with tumor-promoting effects of CD248 in melanoma cells.

Published: November 2022

Abstract
Background
The overdose crisis in Canada has worsened since the emergence of the COVID-19 pandemic. Although this trend is thought to be driven in part by closures or reduced capacity of supervised consumption services (SCS), little is known about the factors that may impede access to such services during the COVID-19 pandemic among people who use drugs. This study sought to characterize the prevalence and correlates of having difficulty accessing SCS during the COVID-19 pandemic among people who use drugs in Vancouver, Canada.

Methods
Cross-sectional data from two open prospective cohorts of people who use drugs were collected via phone or videoconferencing interviews conducted between July 2020 and November 2020. Multivariable logistic regression analyses were used to examine factors associated with experiencing difficulty accessing SCS.

Results
Among the 428 people who use drugs who participated in the study, 223 (54.7%) self-identified as men and the median age was 51 years (1st to 3rd quartile: 42–58). A total of 58 (13.6%) participants reported experiencing difficulty accessing SCS. In a multivariable analysis, factors positively associated with difficulty accessing SCS included daily crystal methamphetamine use (Adjusted odds ratio [AOR] = 2.60; 95% confidence interval [CI] 1.28–5.30), active injection drug use (AOR = 4.06; 95% CI 1.38–11.90), recent non-fatal overdose (AOR = 2.45; 95% CI 1.24–4.85), and unstable housing (AOR = 2.14; 95% CI 1.08–4.23). Age was inversely associated with the outcome (AOR = 0.96; 95% CI 0.93–0.99) in multivariable analyses. The most commonly reported reasons for experiencing difficulty accessing SCS were: COVID-19-related site closure or shortened hours (42.9%) and having to wait too long to use a site (39.3%).

Conclusions
We found that people who use drugs with markers of structural vulnerability and drug-related risk were more likely to experience difficulty accessing SCS during the COVID-19 pandemic. These findings point to the need for strategies to support access to such services as part of pandemic response efforts.
Emergency versus delayed hepatectomy following transarterial embolization in spontaneously ruptured hepatocellular carcinoma survivors: a systematic review and meta-analysis
Authors: Zhang Wei , Huang Zhangkan , Che Xu 
Published: November 2022

Abstract
Background
Spontaneous rupture is a life-threatening complication of hepatocellular carcinoma (HCC). Recent trends in surgical treatments avoid emergency hepatectomy (EH) and favor emergency transarterial embolization (TAE) followed by delayed hepatectomy (DH). Still, there is debate on which is the better treatment option and whether delaying hepatectomy increases peritoneal metastasis.

Aim
To provide evidence-based references for the optimal management of patients with spontaneously ruptured HCC by comparing the outcomes of EH and DH.

Methods
Literature on postoperative outcomes of EH and DH in patients with spontaneously ruptured HCC published between the date of the database establishment and May 2022, was identified in the PubMed, EMBASE, and Cochrane Library databases. Revman 5.3 software was used for statistical analyses.

Results
Nine publications were identified, including a total of 681 patients. Of those, 304 underwent EH, and 377 underwent TAE followed by DH. The meta-analysis results indicated that the in-hospital mortality rate in the EH patient group was significantly higher than that in the DH patient group (relative risk (RR) = 2.17, 95% confidence interval (CI) 1.03–4.57, p =0.04). There was no significant differences in the rates of postoperative complications (RR = 1.21, 95% CI 0.77–1.90, p = 0.40), postoperative hospital stay (WMD = − 0.64, 95% CI − 5.61–4.34, p = 0.80), recurrence (RR = 1.09, 95% CI 0.94–1.25, p = 0.27), peritoneal metastasis (RR = 1.06, 95% CI 0.66–1.71, p = 0.80), 1-year survival (RR = 0.91, 95% CI 0.80–1.02, p = 0.11), or 3-year survival (RR = 0.81, 95% CI 0.61–1.09, p = 0.17) in survivors between the two patient groups.

Conclusion
The postoperative outcomes of the spontaneously ruptured HCC survivors who received EH were similar to those who received emergency TAE followed by DH. However, the in-hospital mortality rate was higher in EH patients. Based on the findings, DH with TAE first strategy might be considered over EH as the first line treatment modality. However, these findings await further validation by future high-quality studies.
