Authors: Forchuk Cheryl , Gyamfi Sebastian , Hassan Heba , Lucyk Bryanna , Booth Richard 
Published: February 2023

Abstract
Background
Recovery-oriented programs provide individuals with opportunities for well-being through community integration processes that enhance the degree to which individuals could live, work, and recreate in their community. The current evaluation assessed how tenants experience their home environment after the modernization of Homes for Special Care (HSC) to Community Homes for Opportunity (CHO) in Southwest Ontario, Canada. Our study identifies existing policies and practices that could interfere with or promote the modernization process.

Methods
We applied ethnographic qualitative techniques to purposefully recruit 188 participants with severe mental illness from 28 group homes. Focus groups were conducted at three time points, i.e., at pre-implementation/Baseline/Time I – spring 2018; Transition/Time II – fall 2018, and Final/Time III – winter 2019.

Results
Study findings suggest that the transition of HSC to CHO supports activities that empower tenants towards personal growth and development. Participants were largely satisfied with the support they were getting in relation to the program-related services. Tenants disclosed that their quality of life and well-being had been enhanced through participating in the program, and that their social interaction and support for each other had also improved. Most tenants demonstrated autonomy in terms of personal and financial independence. The enhanced financial support for tenants did not only improve their quality of life, but also helped to raise their purchasing power, decision making, sense of responsibility and accountability towards healthy spending of their resources. Despite tenants’ good impression about the CHO, some still encountered problems and provided suggestions to further improve the program.

Conclusion
It is expected that a more effective and expanded CHO will lead to tenant empowerment and successful social integration.

Abstract
Background
Floods and torrential rains are natural disasters caused by climate change. Unfortunately, such events are more frequent and are increasingly severe in recent times. The 2018 Japan Floods in western Japan were one of the largest such disasters. This study aimed to evaluate the effect of the 2018 Japan Floods on healthcare costs and service utilization.

Methods
This retrospective cohort study included all patients whose receipts accrued between July 2017 and June 2019 in Hiroshima, Okayama, and Ehime prefectures using the National Database of Health Insurance Claims. We used Generalized Estimating Equations (GEEs) to investigate yearly healthcare costs during the pre-and post-disaster periods, quarterly high-cost patients (top 10%), and service utilization (outpatient care, inpatient care, and dispensing pharmacy) during the post-disaster period. After the GEEs, we estimated the average marginal effects as the attributable disaster effect.

Results
The total number of participants was 5,534,276. Victims accounted for 0.65% of the total number of participants (n = 36,032). Although there was no significant difference in pre-disaster healthcare costs (p = 0.63), post-disaster costs were $3,382 (95% CI: 3,254–3,510) for victims and $3,027 (95% CI: 3,015–3,038) for non-victims (p < 0.001). The highest risk difference among high-cost patients was 0.8% (95% CI: 0.6–1.1) in the fourth quarter. In contrast, the highest risk difference of service utilization was in the first quarter (outpatient care: 7.0% (95% CI: 6.7–7.4), inpatient care: 1.3% (95% CI: 1.1–1.5), and dispensing pharmacy: 5.9% (95% CI: 5.5–6.4)).

Conclusion
Victims of the 2018 Japan Floods had higher medical costs and used more healthcare services than non-victims. In addition, the risk of higher medical costs was highest at the end of the observation period. It is necessary to estimate the increase in healthcare costs according to the disaster scale and plan for appropriate post-disaster healthcare service delivery.
Disparities in the first-ever diagnosed liver cancers between the emergency department and outpatient department in Taiwan: a population-based study

Published: February 2023

Abstract
Background
Liver cancer is ranked fifth in incidence and second in mortality among cancers in Taiwan. Nevertheless, the Taiwan government does not screen for liver cancer in its free cancer screening and preventive health examination service. This study compared the differences in cancer stage and survival between patients who received an initial liver cancer diagnosis in outpatient departments (OPDs) and those who received such a diagnosis in emergency departments (EDs).

Methods
This retrospective cohort study used the 2000–2016 National Health Insurance Database to obtain a sample from 2 million Taiwanese residents. To evaluate the effect of the utilization of the adult health examination offered to people aged ≥ 40 years, patients aged ≥ 40 years who received an initial liver cancer diagnosis between 2003 and 2015 were followed up until December 31, 2016.

Results
In total, 2,881 patients were included in this study. A greater proportion of cancer cases in the OPD group were non-advanced than those in the ED group (75.26% vs. 54.23%). Having stage C or D cancer, having a low monthly salary, and a Charlson comorbidity index score ≥ 8, not having hepatitis B, being divorced, and attending a non-public hospital as the primary care institution were risk factors for initial ED diagnosis. The risk of liver cancer-specific death among the ED group patients was 1.38 times that among the OPD group patients (adjusted hazard ratio = 1.38, 95% confidence interval [CI] = 1.14–1.68, P < 0.001). However, the use of health examination did not exert a significant effect on the likelihood of liver cancer diagnosis in an ED (adjusted odds ratio = 0.86, 95% CI = 0.61–1.21, P = 0.381).

Conclusion
Government-subsidized health examinations are insufficient to prevent first-ever diagnosed liver cancers in EDs. Patients with liver cancers diagnosed in EDs had a higher risk of advanced stage and mortality. For early detection and treatment, the government may consider implementing liver cancer screening for high-risk and low-socioeconomic people.
In vitro culture of bovine fibroblasts using select serum-free media supplemented with Chlorella vulgaris extract
Authors: Defendi-Cho Galileo , Gould Timothy M. 
Published: February 2023

AbstractStandard cell culture practices require the addition of animal-derived serum to culture media to achieve adequate cell growth. Typically, 5–10% by volume of fetal bovine serum (FBS) is used, which accounts for a vast majority of the media cost while also imposing environmental and ethical concerns associated with the use of animal serum. Here we tested the efficacy of culturing cells by replacing serum in the media with algae extract and select additives. Using LC–MS, we compared molecular signatures of FBS to Chlorella algae extracts and identified NAD(H)/NADP(H) as common and relatively abundant features in their characteristic profiles. Bovine fibroblasts, cultured in serum-free media supplemented with C. vulgaris extract and just two growth factors plus insulin, showed significant growth with enhanced viability compared to control cells cultured without serum, albeit still lower than that of controls cultured with 10% FBS. Moreover, C. vulgaris extract enhanced cell viability beyond that of cells cultured with the two growth factors and insulin alone. These results suggest that key components in serum which are essential for cell growth may also be present in C. vulgaris extract, demonstrating that it may be used at least as a partial alternative to serum for cell culture applications.

Abstract
Background
Extensively drug-resistant (XDR) Salmonella enterica serovar Typhi (S. Typhi) poses a grave threat to public health due to increased mortality and morbidity caused by typhoid fever. Honey is a promising antibacterial agent, and we aimed to determine the antibacterial activity of honey against XDR S. Typhi.

Methods
We isolated 20 clinical isolates of XDR S. Typhi from pediatric septicemic patients and determined the minimum inhibitory concentrations (MICs) of different antibiotics against the pathogens using the VITEK 2 Compact system. Antimicrobial-resistant genes carried by the isolates were identified using PCR. The antibacterial efficacy of five Pakistani honeys was examined using agar well diffusion assay, and their MICs and minimum bactericidal concentrations (MBCs) were determined with the broth microdilution method.

Results
All 20 isolates were confirmed as S. Typhi. The antibiogram phenotype was confirmed as XDR S. Typhi with resistance to ampicillin (≥ 32 µg/mL), ciprofloxacin (≥ 4 µg/mL), and ceftriaxone (≥ 4 µg/mL) and sensitivity to azithromycin (≤ 16 µg/mL) and carbapenems (≤ 1 µg/mL). Molecular conformation revealed the presence of blaTM-1, Sul1, qnrS, gyrA, gyrB, and blaCTX-M-15 genes in all isolates. Among the five honeys, beri honey had the highest zone of inhibition of 7–15 mm and neem honey had a zone of inhibition of 7–12 mm. The MIC and MBC of beri honey against 3/20 (15%) XDR S. Typhi isolates were 3.125 and 6.25%, respectively, while the MIC and MBC of neem were 3.125 and 6.25%, respectively, against 3/20 (15%) isolates and 6.25 and 12.5%, respectively, against 7/20 (35%) isolates.

Conclusion
Indigenous honeys have an effective role in combating XDR S. Typhi. They are potential candidates for clinical trials as alternative therapeutic options against XDR S. Typhi isolates.

Authors: Xue Xiang , Luo Xianyuan , Liu Zhaoyang , Jin Yun 
Published: February 2023

AbstractBackgroundMastering cardiac anatomy is a formidable obstacle in the learning process for cardiac electrophysiology trainees. The complex three-dimensional characteristics and contiguous relationship of the ventricular outflow tract are particularly difficult to visualize with the limited study methods available. The hands can recreate a morphology similar to the ventricular outflow tract; this study explored whether a two-handed model of the heart helps electrophysiology trainees improve their understanding of ventricular outflow tract anatomy.MethodsAfter an initial assessment, trainees were randomly placed into variable and control groups. Subsequently, all trainees learned the outflow tract anatomy using routine methods, with the variable group receiving additional instruction using the two-handed model. One day and one week after the course conclusion, knowledge of the ventricular outflow tract anatomy was assessed for the participants in both groups.ResultsThirty-eight trainees participated (19 in each group). The median scores obtained for the first, second, and third tests were 38 (24,55), 80 (70,86), and 75 (70,81) points, respectively. In the second test, trainees in the variable group had a mean score 6.8 points higher than those in the control group (p = 0.103); in the last test, the mean score was 9.7 points higher in the variable group than in the control group (p = 0.003).ConclusionsIt is convenient to use hands to create a model representing the ventricular outflow tract. Trainees using this model had a better understanding and retention of the ventricular outflow tract anatomy compared to those of the control group.

Abstract
Background
The World Health Organization (WHO) and the Uganda Ministry of Health recommend differentiated service delivery models (DSDMs) as patient-centered antiretroviral therapy (ART) mechanisms for people living with HIV/AIDS (PLHIV) with undetectable viral loads. We studied patient satisfaction with ART services, and its associated factors amongst PLHIV enrolled in DSDMs in Uganda.

Methods
This cross-sectional study involved a random sample of PLHIV accessing DSDM-related ART at nine facilities in East Central Uganda. Eligible patients were adult PLHIV (≥18 years), on ART, and enrolled for at least 12 months in one of three DSDMs: Community Client-Led ART Delivery (CCLAD), Community Drug Distribution Points (CDDP), or Fast-Track Drug Refill (FTDR). We collected data from June to July 2019. A validated tool measured satisfaction. General Estimating Equations with modified Poisson regression and exchangeable correlation structures accounted for clustering at health facilities and identified DSDM-related satisfaction factors.

Results
Of 842 participants enrolled, 530 (63.5%) accessed HIV care through CDDP, 166 (20.1%) through CCLAD, and 146 (16.3%) through FTDR; 541 (64.2%) were satisfied with DSDM services: 78.7% in CDDP, 42.8% in CCLAD, and 36.3% in FTDR. The delivery and treatment factors positively associated with satisfaction included: being enrolled on CDDP [adjusted prevalence ratio (aPR) = 1.51, 95% CI:1.47–1.56] or FTDR [aPR = 1.47, 95% CI:1.26–1.71] relative to CCLAD and being enrolled in a DSDM for more than 3 years [aPR = 1.28, 95% CI:1.11–1.48]. Poor ART adherence [aPR = 0.33, 95% CI:0.19–0.56] and having a baseline WHO HIV stage of 3 or 4 [aPR = 0.36, 95% CI:0.20–0.64] relative to stages 1 and 2 were negatively associated. Among socioeconomic factors, having lower transport costs (< $1.35) per clinic visit [aPR = 1.34, 95% CI:1.17–1.53], being employed [aPR = 1.61, 95% CI:1.38–1.87], and being single [aPR = 1.10, 95% CI:1.08–1.13] were positively associated with satisfaction; drinking alcohol at least once a week [aPR = 0.77, 95% CI:0.63–0.93] was negatively associated with patient satisfaction.

Conclusions
Results showed that 64.2% of patients were satisfied with DSDM services. HIV service delivery and treatment factors (DSDM type, time in DSDM, WHO stage, ART adherence), plus social factors (employment and marital status, transport costs, alcohol consumption), were associated with patient satisfaction. DSDM implementers should tailor services to address these factors to improve patient satisfaction.
The broad use of the Pm8 resistance gene in wheat resulted in hypermutation of the AvrPm8 gene in the powdery mildew pathogen

Published: February 2023

Abstract
Background
Worldwide wheat production is under constant threat by fast-evolving fungal pathogens. In the last decades, wheat breeding for disease resistance heavily relied on the introgression of chromosomal segments from related species as genetic sources of new resistance. The Pm8 resistance gene against the powdery mildew disease has been introgressed from rye into wheat as part of a large 1BL.1RS chromosomal translocation encompassing multiple disease resistance genes and yield components. Due to its high agronomic value, this translocation has seen continuous global use since the 1960s on large growth areas, even after Pm8 resistance was overcome by the powdery mildew pathogen. The long-term use of Pm8 at a global scale provided the unique opportunity to study the consequences of such extensive resistance gene application on pathogen evolution.

Results
Using genome-wide association studies in a population of wheat mildew isolates, we identified the avirulence effector AvrPm8 specifically recognized by Pm8. Haplovariant mining in a global mildew population covering all major wheat growing areas of the world revealed 17 virulent haplotypes of the AvrPm8 gene that grouped into two functional categories. The first one comprised amino acid polymorphisms at a single position along the AvrPm8 protein, which we confirmed to be crucial for the recognition by Pm8. The second category consisted of numerous destructive mutations to the AvrPm8 open reading frame such as disruptions of the start codon, gene truncations, gene deletions, and interference with mRNA splicing. With the exception of a single, likely ancient, gain-of-virulence mutation found in mildew isolates around the world, all AvrPm8 virulence haplotypes were found in geographically restricted regions, indicating that they occurred recently as a consequence of the frequent Pm8 use.

Conclusions
In this study, we show that the broad and prolonged use of the Pm8 gene in wheat production worldwide resulted in a multitude of gain-of-virulence mechanisms affecting the AvrPm8 gene in the wheat powdery mildew pathogen. Based on our findings, we conclude that both standing genetic variation as well as locally occurring new mutations contributed to the global breakdown of the Pm8 resistance gene introgression.
Cold exposure alters lipid metabolism of skeletal muscle through HIF-1α-induced mitophagy

Published: February 2023

Abstract
Background
In addition to its contractile properties and role in movement, skeletal muscle plays an important function in regulating whole-body glucose and lipid metabolism. A central component of such regulation is mitochondria, whose quality and function are essential in maintaining proper metabolic homeostasis, with defects in processes such as autophagy and mitophagy involved in mitochondria quality control impairing skeletal muscle mass and function, and potentially leading to a number of associated diseases. Cold exposure has been reported to markedly induce metabolic remodeling and enhance insulin sensitivity in the whole body by regulating mitochondrial biogenesis. However, changes in lipid metabolism and lipidomic profiles in skeletal muscle in response to cold exposure are unclear. Here, we generated lipidomic or transcriptome profiles of mouse skeletal muscle following cold induction, to dissect the molecular mechanisms regulating lipid metabolism upon acute cold treatment.

Results
Our results indicated that short-term cold exposure (3 days) can lead to a significant increase in intramuscular fat deposition. Lipidomic analyses revealed that a cold challenge altered the overall lipid composition by increasing the content of triglyceride (TG), lysophosphatidylcholine (LPC), and lysophosphatidylethanolamine (LPE), while decreasing sphingomyelin (SM), validating lipid remodeling during the cold environment. In addition, RNA-seq and qPCR analysis showed that cold exposure promoted the expression of genes related to lipolysis and fatty acid biosynthesis. These marked changes in metabolic effects were associated with mitophagy and muscle signaling pathways, which were accompanied by increased TG deposition and impaired fatty acid oxidation. Mechanistically, HIF-1α signaling was highly activated in response to the cold challenge, which may contribute to intramuscular fat deposition and enhanced mitophagy in a cold environment.

Conclusions
Overall, our data revealed the adaptive changes of skeletal muscle associated with lipidomic and transcriptomic profiles upon cold exposure. We described the significant alterations in the composition of specific lipid species and expression of genes involved in glucose and fatty acid metabolism. Cold-mediated mitophagy may play a critical role in modulating lipid metabolism in skeletal muscle, which is precisely regulated by HIF-1α signaling.

Published: February 2023

Abstract
Background
Stress hyperglycemia ratio (SHR) is significantly related to adverse cardiovascular clinical outcomes and increased in-hospital mortality. However, the relationship between SHR and coronary artery disease (CAD) severity has hitherto not been reported. This study sought to clarify the relationship between the SHR and CAD severity of individuals with different glucose metabolic statuses.

Methods
A retrospective analysis was performed on 987 patients who underwent coronary angiography (CAG) from October 2020 to May 2022. Based on CAG results, patients were divided into single-vessel CAD and multi-vessel CAD groups. All subjects were stratified into three groups according to the tertiles of the SHR (T1 group: SHR < 0.930; T2 group: 0.930 ≤ SHR < 1.154; T3 group: 1.154 ≤ SHR). Moreover, according to glucose metabolism status, study subjects were divided into normal glucose regulation (NGR), pre-diabetes mellitus (pre-DM) and diabetes mellitus (DM) groups. Finally, the correlation between SHR and CAD severity was analyzed by logistic regression analysis and receiver operating characteristic (ROC) curve.

Results
The results showed significantly higher SHR in the multi-vessel CAD group than in the single-vessel group. Logistic regression analysis showed that SHR was an independent risk factor for multi-vessel CAD when used as a continuous variable (OR, 4.047; 95% CI 2.137–7.663; P < 0.001). After adjusting for risk factors, the risk of multi-vessel CAD in the T2 and T3 groups was 1.939-fold (95% CI 1.341–2.804; P < 0.001) and 1.860-fold (95% CI 1.272–2.719; P = 0.001) higher than in the T1 group, respectively. The area under the curve (AUC) of ROC plots was 0.613 for SHR. In addition, SHR was significantly correlated with an increased risk of multi-vessel CAD in the pre-DM and DM groups.

Conclusions
Our study indicated that SHR was significantly correlated with the risk of multi-vessel CAD and predicted CAD severity, especially in pre-DM and DM patients.
