Published: November 2022

Alveolar macrophages play a vital role in the development of acute silicosis, but the dynamic changes of M1 and/or M2 phenotypes have not been elucidated. In this study, acute silicosis models of rat were established by a one-time dusting method, and the rats were sacrificed after 1, 3, 7, 14, and 28 days. The polarity states of macrophages were assessed by measuring the M1/M2 marker genes of alveolar macrophages and the M1/M2 marker proteins in bronchoalveolar lavage fluid. The pathological changes of lung tissues were examined with hematoxylin and Eosin and Masson’s trichrome staining. Our results showed that in the early stages, alveolar macrophages were mainly polarized into M1; with time, the polarization of M2 gradually became dominant. Microscopic sections showed significant pathological responses of inflammation and fibrosis. This work suggested that the alteration of alveolar macrophage polarization was involved in the lung pathologic responses to acute silicosis.
Matters of the Heart: Childhood Maltreatment, Religious Transitions, and Cardiovascular-Related Problems over the Life Course
Authors: Upenieks Laura , Thomas Patricia A. 
Published: November 2022

Objectives: Childhood maltreatment is associated with a higher risk of cardiovascular-related problems, the leading cause of death in the United States. Drawing from cumulative inequality theory, this study considers whether transitions in religious attendance moderate the deleterious impact of childhood maltreatment on long-term cardiovascular risk. Methods: We utilize over 35 years of prospective panel data from the National Longitudinal Study of Youth from the United States (1979–2015). Results: Our findings suggest that decreases in religious attendance between adolescence and adulthood (from high to low, and high to moderate attendance) were associated with elevated cardiovascular-related risk for those abused as children. Neither stable high attendance nor increases in attendance buffered against the impact of childhood abuse on cardiovascular-related problems. Discussion: We illustrate the importance of incorporating the role of stability and change in religious attendance across the life course and suggest directions for future research.

Published: November 2022

Objective Hydroxychloroquine (HCQ) is widely used in patients with systemic lupus erythematosus (SLE), but its effects on the mortality have not reached a definite conclusion. In this systematic review and meta-analysis, we aimed to assess whether HCQ use could reduce the risk of mortality in SLE patients. Methods PubMed, Embase, Web of Science, and Cochrane database were searched from inception to April 17, 2022 without language restrictions to explore the relationship between HCQ use and SLE mortality. The relative risk (HR) was pooled using the STATA software. Results A total of 21 studies with a pooled patient population of 26,037 were included in the study, including 14 studies on the association between HCQ alone and mortality risk and seven studies on the association between HCQ/chloroquine (CQ) and mortality risk. The pooled findings suggested that HCQ significantly reduced the overall mortality risk of SLE (pooled HR 0.46, 95% CI 0.38–0.57, p < 0.001). In subgroup analysis of SLE complications, HCQ use also decreased the risk of death in SLE patients with renal (HR=0.43, 95% CI 0.26–0.70, p = 0.001) and cardiopulmonary involvement (HR=0.37, 95% CI= 0.25–0.54, p < 0.001). In addition, HCQ use was also protective against the risk of mortality in SLE patients in different regions, such as Asia (HR=0.46, 95% CI=0.33–0.64, p < 0.001), Europe (HR= 0.40, 95% CI = 0.22–0.71, p = 0.002), and America (HR=0.52, 95% CI= 0.42–0.64, p < 0.001). Conclusion Our data suggested that HCQ use was associated with a reduced risk of mortality in patients with SLE.
Methylation of CpG Sites as Biomarkers Predictive of Drug-Specific Patient Survival in Cancer
Authors: Neary Bridget , Lin Shuting , Qiu Peng 
Published: November 2022

Background: Though the development of targeted cancer drugs continues to accelerate, doctors still lack reliable methods for predicting patient response to standard-of-care therapies for most cancers. DNA methylation has been implicated in tumor drug response and is a promising source of predictive biomarkers of drug efficacy, yet the relationship between drug efficacy and DNA methylation remains largely unexplored. Method: In this analysis, we performed log-rank survival analyses on patients grouped by cancer and drug exposure to find CpG sites where binary methylation status is associated with differential survival in patients treated with a specific drug but not in patients with the same cancer who were not exposed to that drug. We also clustered these drug-specific CpG sites based on co-methylation among patients to identify broader methylation patterns that may be related to drug efficacy, which we investigated for transcription factor binding site enrichment using gene set enrichment analysis. Results: We identified CpG sites that were drug-specific predictors of survival in 38 cancer-drug patient groups across 15 cancers and 20 drugs. These included 11 CpG sites with similar drug-specific survival effects in multiple cancers. We also identified 76 clusters of CpG sites with stronger associations with patient drug response, many of which contained CpG sites in gene promoters containing transcription factor binding sites. Conclusion: These findings are promising biomarkers of drug response for a variety of drugs and contribute to our understanding of drug-methylation interactions in cancer. Investigation and validation of these results could lead to the development of targeted co-therapies aimed at manipulating methylation in order to improve efficacy of commonly used therapies and could improve patient survival and quality of life by furthering the effort toward drug response prediction.

Published: November 2022

Background: Africa is contending with unhealthy food environments that are, in part, driving increasing rates of overweight, obesity and diet-related non-communicable diseases, alongside persistent undernutrition. This current paradigm requires expanded efforts – both in the volume and nature of empirical research, as well as the tools and capacity of those who conduct it. High quality and context-relevant research supports the development and implementation of policies that create healthy food environments. Aim and approach: This paper sets out the concept of the Africa Food Environment Research Network (FERN) initiative recently established by the Measurement, Evaluation, Accountability, and Leadership Support for non-communicable diseases (NCDs) (MEALS4NCDs) prevention project. Central to the Africa FERN initiative are: 1) building research capacity for innovative food environment research in Africa; 2) improving South–South, South–North partnerships to stimulate robust food environment research and monitoring in Africa and 3) sustaining dialogue and focusing priorities around current and future needs for enhanced food environment research and monitoring in Africa. Conclusion: The FERN initiative presents an opportune platform for researchers in Africa and the global North to weave the threads of experience and expertise for research capacity building, collaboration and advocacy, to advance food environment research.

Published: November 2022

Abstract
Background
BTBD7_hsa_circ_0000563 is a novel circRNA and contains conserved binding sites with RNA-binding proteins. However, BTBD7_hsa_circ_0000563 has not been fully studied in coronary artery disease (CAD). We aimed to clarify the diagnostic value and the possible functional role of BTBD7_hsa_circ_0000563 in CAD.

Methods
A total of 276 human peripheral blood mononuclear cell (PBMC) samples were employed. The circularization of BTBD7_hsa_circ_0000563 was verified via Sanger sequencing. The expression level of BTBD7_hsa_circ_0000563 in CAD samples and control individuals was analysed via qRT–PCR. The diagnostic potential of BTBD7_hsa_circ_0000563 was evaluated using Spearman’s analysis, univariate and multivariable logistic regression analysis, and receiver-operator characteristic (ROC) curve analysis. ChIRP-MS was performed to directly explore the proteins bound to BTBD7_hsa_circ_0000563. Bioinformatic analysis was conducted to investigate the possible functions and interactions of proteins bound to BTBD7_hsa_circ_0000563.

Results
In the present study, BTBD7_hsa_circ_0000563 was verified as a circular RNA in the PBMCs of CAD patients. The expression level of BTBD7_hsa_circ_0000563 in the CAD group was significantly lower than that in the control group. The area under the ROC curve was 0.690. ChIRP-MS found seven proteins that were directly bound to BTBD7_hsa_circ_0000563. Bioinformatic analysis of these seven proteins showed that the mitophagy and DNA repair pathways were enriched. These proteins interacted with each other to a certain extent.

Conclusion
BTBD7_hsa_circ_0000563 may be a novel biomarker for the diagnosis of CAD and may influence the initiation and progression of CAD. These studies may reveal new possibilities for the diagnosis and treatment of CAD.

Authors: Esmaeily Zahra , Daei Shahrzad , Rezaei Mahshid , Eyvazkhani Atefeh , Tajary Zahra , Dara Marjan Mansouri , Motlagh Ahmad Reza Dorosty 
Published: November 2022

Abstract
Background
Unlike the numerous studies concerning the role of dietary inflammatory potential in chronic diseases, limited studies focused on the association of dietary inflammatory potential with handgrip strength (HGS) and probable sarcopenia (PS). This study tends to explore the association between dietary inflammatory potential and PS among older adults in Tehran.

Methods
The cross-sectional study was conducted between May and October 2019 on 201 randomly selected older adults in Tehran, Iran. A validated food frequency questionnaire was utilized for recording dietary intake. Dietary habits were evaluated through Dietary Inflammatory Index (DII) and Empirical Dietary Inflammatory Index (EDII). PS assessment was done by HGS estimation. Statistical evaluation included descriptive analyses, logistic, and linear regression.

Results
Those probably suffering from sarcopenia were older than healthy ones (p < 0.0001) and had significantly higher DII scores (p = 0.05) but not EDII (p = 0.85). Besides, PS subjects had a lower intake of anti-inflammatory nutrients. The odds of PS were doubled in people on the top tertile of DII (OR = 2.49, 95% (CI) = 1.11–5.58) and second tertile of EDII (OR = 2.29, 95% (CI) = 1.03–5.07) relative to bottom tertiles after adjusting for confounders. The relationships between index scores and HGS were simply significant in the adjusted model of EDII and HGS (B = -0.49, p = 0.04).

Conclusion
Conclusively, participants adhering to a pro-inflammatory diet had more likelihood of PS. Findings are in line with current recommendations to reduce unhealthy foods with more inflammatory potential. These findings warrant confirmation in high-quality interventional studies.

Abstract
Background
Brazil, China, Kazakhstan, and Russia are the main asbestos-producing countries, and all forms of asbestos are carcinogenic to humans. The objective of this study was to estimate the disease burden attributable to asbestos between 1990 and 2019 in major producing countries, including Brazil, China, Kazakhstan, and Russia.

Methods
Age-standardized mortality rates (ASMR) and age-standardized disability-adjusted life year (DALY) rates (ASDR) of disease burden attributable to asbestos by country, age, and sex were extracted from the Global Burden of Disease 2019. Percentage change and estimated annual percentage change (EAPC) were used to assess the trends of ASDR and ASMR of disease burden attributable to asbestos between 1990 and 2019.

Results
Asbestos-related diseases were highly heterogeneous across Global, Brazil, China, Kazakhstan, and Russia. There was a downward trend in ASMR and ASDR of diseases burden related to asbestos globally. The age-specific mortality rate of disease attributable to asbestos increased in men and women, although it decreased in women aged 85–89, the highest age-specific mortality rate were observed in age 95 + group in men [162.14 (95% UI: 103.76–215.45)] and women [30.58 (95% UI: 14.83–44.33)] per 100 000 population, respectively. Tracheal, bronchus, and lung (TBL) cancer was the leading cause of death and DALYS attributable to asbestos between 1990 and 2019 globally and in Brazil, China, Kazakhstan, and Russia. China had the highest percentage change (73.31%) and EAPC [3.41 (95% CI: 2.75–4.08)] in ASMR related to exposure to asbestos in men, with the highest percentage change (73.31%) and EAPC [3.41 (95% CI: 2.75–4.08)] in ASDR in men.

Conclusions
The ASMR and ASDR of disease burden attributable to asbestos decreased between 1990 and 2019 globally. TBL cancer was the leading cause of death and DALYs attributable to asbestos between 1990 and 2019. There has been an increasing trend in mortality and DALYs globally, especially in older men. The burden of disease attributable to asbestos is increasing in China, especially in men.
The influence of obesity on functional outcomes and patient satisfaction 8 weeks after total knee arthroplasty: results of the prospective FInGK study
Authors: Baum Gesa , Jacobs Hannes , Lazovic Djordje , Maus Uwe , Hoffmann Falk , Seeber Gesine H. 
Published: November 2022

Abstract
Objectives
To investigate obese versus non-obese subjects´ knee joint function, stiffness, pain, expectations, and outcome satisfaction before and two months after total knee arthroplasty (TKA).

Methods
This study is a secondary analysis of data retrieved via a prospective single-centre cohort study investigating knee joint function and health care services utilization in patients undergoing TKA (FInGK Study). For the primary study, elective TKA patients were consecutively recruited between December 2019 and May 2021. Preoperative expectations, Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), surgery outcome satisfaction, and sociodemographic variables were assessed via self-reported questionnaires. In the current study, obese (Body Mass Index (BMI) ≥ 30 kg/m²) versus non-obese (BMI < 30 kg/m²) subjects’ data were exploratively compared before and two months after TKA. Multivariable logistic regression assessed factors associated with TKA satisfaction two months postoperatively. Linear regression evaluated factors associated with higher WOMAC change two months postoperatively.

Results
A total of 241 subjects participated (response: 85.2%). Eighty-seven were non-obese (mean age: 70.7 years, 63.2% female) and 154 were obese (mean age: 67.1 years, 57.8% female). Obese subjects reported inferior pre- and postoperative pain and knee joint function compared to non-obese subjects. Yet, WOMAC scores of obese and non-obese subjects significantly improved from preoperative means of 52.6 and 46.8 to 32.3 and 24.4 after surgery, respectively. The only significant TKA satisfaction predictor was subjects’ smoking status. Non-obesity and worse preoperative WOMAC scores were predictive of higher WOMAC change scores after two months.

Conclusion
Both obese and non-obese subjects reported significant symptom improvements. However, as obese subjects’ short-term outcomes were still inferior, more research on TKA rehabilitation measures adapted to the needs of this growing patient group is warranted to maximize their benefits from TKA.
Operationalization of assent for research participation in pre-adolescent children: a scoping review
Authors: Cayouette Florence , O’Hearn Katie , Gertsman Shira , Menon Kusum 
Published: November 2022

Abstract
Background
Seeking assent from children for participation in medical research is an ethical imperative of numerous institutions globally. However, none of these organizations provide specific guidance on the criteria or process to be used when obtaining assent. The primary objective of this scoping review was to determine the descriptions of assent discussed in the literature and the reported criteria used for seeking assent for research participation in pre-adolescent children.

Methods
Medline and Embase databases were searched until November 2020 using the term “assent” in the title or abstract. Inclusion criteria were (1) studies enrolling children which specifically described operationalization of the assent process and (2) studies of the assent process which provided a description of assent. Data collected included participant information, patient criteria for seeking assent, guidelines referenced, description of assent reported, how assent was obtained and assent information presented, and reported assent rate. For qualitative articles focusing on the assent process, important themes were identified.

Results
A total of 116 articles were included of which 79 (68.9%) operationalized assent and 57 studies (%) described the assent process. The most commonly reported criterion used to determine the ability of a child to assent was age (35.4%, 28/79). The reported minimal age for obtaining pediatric assent varied considerably across and within jurisdictions (5–13 years; median 7.5 years, IQR 7.0, 9.75). Cognitive ability was reported as a criterion for obtaining assent in 5.1% (4/79) of studies. Assent rates were only reported in 17.7% (14/79) of citations and ranged from 32.0 to 100%. Analysis of the 57 studies describing the assent process identified several themes, including age thresholds, assessment of capacity, variable knowledge of pediatric assent and parental roles.

Conclusion
We found significant variation in criteria used for assessment of patient capacity, delivery of information used to obtain assent and documentation of the assent process. While we acknowledge that individual children, settings and jurisdictions may require different approaches to obtaining assent, there should be agreement on important principles to be followed with resulting common guidance on assessing capacity, delivering information and documentation of the assent process for publication.

Published: November 2022

Abstract
Background
The use of palm oil for our current needs is unsustainable. Replacing palm oil with oils produced by microbes through the conversion of sustainable feedstocks is a promising alternative. However, there are major technical challenges that must be overcome to enable this transition. Foremost among these challenges is the stark increase in lipid accumulation and production of higher content of specific fatty acids. Therefore, there is a need for more in-depth knowledge and systematic exploration of the oil productivity of the oleaginous yeasts. In this study, we cultivated Cutaneotrichosporon oleaginosus and Yarrowia lipolytica at various C/N ratios and temperatures in a defined medium with glycerol as carbon source and urea as nitrogen source. We ascertained the synergistic effect between various C/N ratios of a defined medium at different temperatures with Response Surface Methodology (RSM) and explored the variation in fatty acid composition through Principal Component Analysis.

Results
By applying RSM, we determined a temperature of 30 °C and a C/N ratio of 175 g/g to enable maximal oil production by C. oleaginosus and a temperature of 21 °C and a C/N ratio of 140 g/g for Y. lipolytica. We increased production by 71% and 66% respectively for each yeast compared to the average lipid accumulation in all tested conditions. Modulating temperature enabled us to steer the fatty acid compositions. Accordingly, switching from higher temperature to lower cultivation temperature shifted the production of oils from more saturated to unsaturated by 14% in C. oleaginosus and 31% in Y. lipolytica. Higher cultivation temperatures resulted in production of even longer saturated fatty acids, 3% in C. oleaginosus and 1.5% in Y. lipolytica.

Conclusions
In this study, we provided the optimum C/N ratio and temperature for C. oleaginosus and Y. lipolytica by RSM. Additionally, we demonstrated that lipid accumulation of both oleaginous yeasts was significantly affected by the C/N ratio and temperature. Furthermore, we systematically analyzed the variation in fatty acids composition and proved that changing the C/N ratio and temperature steer the composition. We have further established these oleaginous yeasts as platforms for production of tailored fatty acids.
The impact of human and livestock respiration on CO2 emissions from 14 global cities

Published: November 2022

Abstract
Background
The CO2 released by humans and livestock through digestion and decomposition is an important part of the urban carbon cycle, but is rarely considered in studies of city carbon budgets since its annual magnitude is usually much lower than that of fossil fuel emissions within the boundaries of cities. However, human and livestock respiration may be substantial compared to fossil fuel emissions in areas with high population density such as Manhattan or Beijing. High-resolution datasets of CO2 released from respiration also have rarely been reported on a global scale or in cities globally. Here, we estimate the CO2 released by human and livestock respiration at global and city scales and then compare it with the carbon emissions inventory from fossil fuels in 14 cities worldwide.

Results
The results show that the total magnitude of human and livestock respiration emissions is 38.2% of the fossil fuel emissions in Sao Paulo, highest amongst the 14 cities considered here. The proportion is larger than 10% in cities of Delhi, Cape Town and Tokyo. In other cities, it is relatively small with a proportion around 5%. In addition, almost 90% of respiratory carbon comes from urban areas in most of the cities, while up to one-third comes from suburban areas in Beijing on account of the siginificant livestock production.

Conclution
The results suggest that the respiration of human and livestock represents a significant CO2 source in some cities and is nonnegligible for city carbon budget analysis and carbon monitoring.
