Impact of increasing the relative availability of meat-free options on food selection: two natural field experiments and an online randomised trial
Authors: Pechey Rachel , Bateman Paul , Cook Brian , Jebb Susan A. 
Published: January 2022

Abstract
Background
Increasing the availability of lower energy-density foods is a promising intervention to encourage healthier food purchasing but few studies have examined the effect of increasing availability of meat-free meals to promote more sustainable purchasing. We report three studies, all examining the impact of altering the availability of meat-free meals on meal selection.

Methods
Study 1 (a natural experiment in one university cafeteria) examined the impact of altering the ratio of meat-free meals (one meat-free and two meat, to two meat-free and one meat) on weekly sales of meals containing meat. Study 2 (a natural experiment in 18 worksite cafeterias) examined the impact on meat-free meal sales of a menu change designed to increase the availability of meat-free meals. Study 3 (an online study of 2205 UK-representative adults) compared meal selections when participants were randomised to ranges comprised of (a) one meat-free, three meat options; (b) two meat-free, two meat; or (c) three meat-free, one meat.

Results
Study 1 suggested a significant decrease in the proportion of sales of meat options when the availability of meat-free options increased (− 19.9 percentage points; 95%CIs:-25.2,-14.6), with no evidence of changes to meat-based meal sales in other university cafeterias during the same period. Findings from Study 2 were mixed: multilevel regressions found no evidence of an increase in meat-free meals following the menu change (2.3 percentage points; 95%CIs: − 1.3,5.9), while interrupted time-series analyses suggested sales did increase (2.3; 95%CIs: 0.4,4.2), but implementation of the planned change was limited. In Study 3 reducing meat-free options from 50 to 25% reduced participants’ selection of meat-free options (odds ratio 0.35; 95%CIs: 0.26,0.46), while increasing meat-free options from 50 to 75% increased meat-free selections (odds ratio 2.43; 95%CIs: 1.94,3.04). There was no evidence effects were moderated by gender, socioeconomic status or usual meat consumption.

Conclusion
Increasing the availability of meat-free options is effective at reducing meat selection and purchasing for different ratios of meat to meat-free options. The magnitude of the effect is uncertain, but with no evidence of differences in response by demographic groups when directly tested.

Abstract
Background
Although children’s intake of fruit and vegetables has seen a recent rise, almost half of adolescents do not eat even one piece of fruit or vegetables per day. One way to address this problem is through interventions that provide fruit and vegetables directly to children in kindergartens and schools. For such interventions to meet their intended goals, what is important to consider in addition to impact is implementation. Our objective is to systematically review qualitative results reporting on the determinants (barriers and facilitators) to implementation of interventions that entail direct provision of fruit and vegetables in kindergarten and school settings and conduct a framework analysis of those results using the Consolidated Framework for Implementation Research (CFIR).

Methods
A systematic search was designed and run in November 2019 for: MEDLINE (Ovid), Embase (Ovid), PsychINFO (Ovid), ERIC (Ovid), Cochrane Library Reviews and Cochrane Library Trials. A keyword search of the journal Implementation Science was completed. Screening of titles and abstracts (n = 5427) and full texts (n = 227), led to 14 included articles. Coding and analysis were done using the framework method and CFIR.

Results
The following CFIR constructs were found relevant: 1) intervention characteristics domain: ‘design quality and packaging’, ‘adaptability’ ‘cost’; 2) outer setting: ‘cosmopolitanism’, ‘external policy and incentives’ ‘patients’ needs and resources’; 3) inner setting: ‘implementation climate’, ‘readiness for implementation’ and ‘structural characteristics’; 4) characteristics of individuals: ‘individual stage of change’, ‘knowledge and beliefs about the intervention’ 5) process: ‘engaging’, ‘executing’ and ‘reflecting and evaluating’. The review stresses the dual role of parents as both supporting the implementation and targets of the intervention, which could have implications for the design and implementation of future fruit and vegetables interventions. Positive child perceptions of the value of the intervention and perceived behavior change due to the intervention were reported as relevant facilitators to implementation across several studies, and should be taken into consideration in future design efforts.

Conclusions
CFIR offers a systematic way to identify and organize barriers and facilitators to implementation of interventions in the kindergarten and school setting. Revisions are encouraged to allow adequate space for perceptions of various implementation actors and the target group.

Abstract
Background
Colon cancer is a common malignant tumor of the digestive tract, and its incidence is ranked third among gastrointestinal tumors. The present study aims to investigate the role of a novel circular RNA (circCSPP1) in colon cancer and its underlying molecular mechanisms.

Methods
Bioinformatics analysis and reverse transcription-quantitative PCR were used to detect the expression levels of circCSPP1 in colon cancer tissues and cell lines. The effects of circCSPP1 on the behavior of colon cancer cells were investigated using CCK-8, transwell and clonogenic assays. Bioinformatics analysis along with luciferase, fluorescence in situ hybridization and RNA pull-down assays were used to reveal the interaction between circCSPP1, microRNA (miR)-431, Rho associated coiled-coil containing protein kinase 1 (ROCK1) and zinc finger E-box binding homeobox 1 (ZEB1).

Results
It was found that circCSPP1 expression was significantly upregulated in colon cancer tissues and cell lines. Overexpression of circCSPP1 significantly promoted the proliferation, migration and invasion of colon cancer cells, whereas silencing of circCSPP1 exerted opposite effects. Mechanistically, circCSPP1 was found to bind with miR-431. In addition, ROCK1 and ZEB1 were identified as the target genes of miR-431. Rescue experiments further confirmed the interaction between circCSPP1, miR-431, ROCK1 and ZEB1. Moreover, circCSPP1 promoted the expression level of ROCK1, cyclin D1, cyclin-dependent kinase 4, ZEB1 and Snail, and lowered the E-cadherin expression level.

Conclusion
Taken together, the findings of the present study indicated that circCSPP1 may function as a competing endogenous RNA in the progression of colon cancer by regulating the miR-431/ROCK1 and miR-431/ZEB1 signaling axes.
YTHDC1 regulates distinct post-integration steps of HIV-1 replication and is important for viral infectivity

Published: January 2022

Abstract
Background
The recent discovery of the role of m6A methylation in the regulation of HIV-1 replication unveiled a novel layer of regulation for HIV gene expression. This epitranscriptomic modification of HIV-1 RNAs is under the dynamic control of specific writers and erasers. In addition, cytoplasmic readers of the m6A mark are recruited to the modified viral RNAs and regulate HIV-1 replication. Yet, little is known about the effects of m6A writers and readers on the biogenesis of HIV-1 RNAs.

Results
We showed that the METTL3/14 m6A methyltransferase complex and the m6A YTHDF2 cytoplasmic reader down regulates the abundance of HIV-1 RNAs in infected cells. We also identified the m6A nuclear reader YTHDC1 as a novel regulator of HIV-1 transcripts. In HIV-1 producer cells, we showed that knocking down YTHDC1 increases the levels of unspliced and incompletely spliced HIV-1 RNAs, while levels of multiply spliced transcripts remained unaffected. In addition, we observed that depletion of YTHDC1 has no effect on the nuclear cytoplasmic distribution of viral transcripts. YTHDC1 binds specifically to HIV-1 transcripts in a METTL3-dependent manner. Knocking down YTHDC1 reduces the expression of Env and Vpu viral proteins in producer cells and leads to the incorporation of unprocessed Env gp160 in virus particles, resulting in the decrease of their infectivity.

Conclusions
Our findings indicate that, by controlling HIV-1 RNA biogenesis and protein expression, the m6A nuclear reader YTHDC1 is required for efficient production of infectious viral particles.

Published: January 2022

Abstract
Background
The African continent hosts many industrial mining projects, and many more are planned due to recent prospecting discoveries and increasing demand for various minerals to promote a low-carbon future. The extraction of natural resources in sub-Saharan Africa (SSA) represents an opportunity for economic development but also poses a threat to population health through rapid urbanisation and environmental degradation. Children could benefit from improved economic growth through various channels such as access to high-quality food, better sanitation, and clean water. However, mining can increase food insecurity and trigger local competition over safe drinking water. Child health can be threatened by exposure to mining-related air, noise, and water pollution. To assess the impact of mines on child health, we analyse socio-demographic, health, and mining data before and after several mining projects were commissioned in SSA.

Results
Data of 90,951 children living around 81 mining sites in 23 countries in SSA were analysed for child mortality indicators, and 79,962 children from 59 mining areas in 18 SSA countries were analysed for diarrhoea, cough, and anthropometric indicators. No effects of the launch of new mining projects on overall under-five mortality were found (adjusted Odds Ratio (aOR): 0.88; 95% Confidence Interval (CI): 0.68–1.14). However, activation of mining projects reduced the mortality risk among neonates (0–30 days) by 45% (aOR: 0.55; 95% CI: 0.37–0.83) and risk for a child to develop diarrhoeal diseases by 32% (aOR: 0.68; 95% CI: 0,51–0.90). The timing analysis of observed changes showed that there is a significant decline in the risk for childhood diarrhoea (aOR: 0.69; 95% CI: 0.49–0.97), and the mean height-for-age z-scores by 28 percentage points, during the prospection and construction phase; i.e., within four years to the initiation of extraction activity. No effects were found for cough and weight-for-height.

Conclusion
The results presented suggest that the impacts of mining on child health vary throughout the mine’s life cycle. Mining development likely contributes positively to the income and livelihoods of the impacted communities in the initial years of mining operations, particularly the prospection and construction phase; these potential benefits are likely to be at least partially offset by food insecurity and environmental pollution during early and later mining stages, respectively. Further research is warranted to better understand these health impacts and to identify policies that can help sustain the positive initial health impacts of mining projects in the long term.
The impact of CARA mandates on nurse practitioner controlled substance prescribing in Oregon: a cohort study
Authors: Klein Tracy A. , Hartung Daniel , Markwardt Sheila 
Published: January 2022

AbstractBackgroundIn 2017, the United States Comprehensive Addiction and Recovery Act (CARA) expanded authorization to prescribe buprenorphine for opioid use disorder (OUD) to nurse practitioners (NPs). Compared to physicians, NPs were required to complete 16 additional hours of training on controlled substance prescribing before a buprenorphine waiver application. As this differential additional education mandate was seen as a potential barrier, we evaluated the impact of this requirement on both NP waiver acquisition and prescribing of controlled substances, comparing NPs who obtained waivers to those who had not.MethodsThrough 2016–2018 Oregon Prescription Drug Monitoring Program and linked NP licensure data, we identified factors associated with waiver acquisition at baseline (2016) and evaluated changes in controlled substance prescribing before (2016) and after waiver acquisition (2018). Using chi-square and Mann-Whitney U testing, we calculated and described controlled substance prescribing types, rates, and patient level quantities including co-prescribing of benzodiazepines and opioids by NPs. Multivariable linear regression compared prescribing by waivered and non-waivered NPs for significant changes in non-buprenorphine controlled substance prescribing.ResultsWaivered NPs were more likely to have a psychiatric certification, have prior disciplinary action, and have generally higher levels of non-buprenorphine controlled substance prescribing than their non-waivered counterparts. While there was a significant increase in opioid prescriptions per patient among waivered NPs, following CARA implementation, co-prescribing of benzodiazepines and opioids significantly declined among waivered NPs relative to non-waivered NPs.ConclusionsAlthough educational requirements were rescinded in 2021 for most applicants, enhanced opioid prescribing training should be incorporated into professional educational offerings regardless of regulatory mandate. We recommended continued focus on education regarding avoidance of high risk prescribing such as co-prescribing of opioids and benzodiazepines. NPs who acquire waivers may take on higher risk patients already using opioids, and these findings may represent transitions in practice and patient setting.

Published: January 2022

AbstractThere is increasing attention being given to opportunities and approaches to advance health equity using implementation science. To reduce disparities in health, it is crucial that an equity lens is integrated from the earliest stages of the implementation process. In this paper, we outline four key pre-implementation steps and associated questions for implementation researchers to consider that may help guide selection and design of interventions and associated implementation strategies that are most likely to reach and be effective in reducing health disparities among vulnerable persons and communities.

Abstract
Background
The evaluation of automatic segmentation algorithms is commonly performed using geometric metrics. An analysis based on dosimetric parameters might be more relevant in clinical practice but is often lacking in the literature. The aim of this study was to investigate the impact of state-of-the-art 3D U-Net-generated organ delineations on dose optimization in radiation therapy (RT) for prostate cancer patients.

Methods
A database of 69 computed tomography images with prostate, bladder, and rectum delineations was used for single-label 3D U-Net training with dice similarity coefficient (DSC)-based loss. Volumetric modulated arc therapy (VMAT) plans have been generated for both manual and automatic segmentations with the same optimization settings. These were chosen to give consistent plans when applying perturbations to the manual segmentations. Contours were evaluated in terms of DSC, average and 95% Hausdorff distance (HD). Dose distributions were evaluated with the manual segmentation as reference using dose volume histogram (DVH) parameters and a 3%/3 mm gamma-criterion with 10% dose cut-off. A Pearson correlation coefficient between DSC and dosimetric metrics, i.e. gamma index and DVH parameters, has been calculated.

Results
3D U-Net-based segmentation achieved a DSC of 0.87 (0.03) for prostate, 0.97 (0.01) for bladder and 0.89 (0.04) for rectum. The mean and 95% HD were below 1.6 (0.4) and below 5 (4) mm, respectively. The DVH parameters, V$$_{60/65/70\,{\mathrm{Gy}}}$$

The average gamma pass-rate was 85%. The comparison between geometric and dosimetric metrics showed no strong statistically significant correlation.

Conclusions
The 3D U-Net developed for this work achieved state-of-the-art geometrical performance. Analysis based on clinically relevant DVH parameters of VMAT plans demonstrated neither excessive dose increase to OARs nor substantial under/over-dosage of the target in all but one case. Yet the gamma analysis indicated several cases with low pass rates. The study highlighted the importance of adding dosimetric analysis to the standard geometric evaluation.

Authors: Migliorini Filippo , Marsilio Emanuela , Oliva Francesco , Eschweiler Jörg , Hildebrand Frank , Maffulli Nicola 
Published: January 2022

Abstract
Background
Patellar dislocations in patients presenting with recurrent patellofemoral instability can damage the surrounding structures, limiting patient’s participation to recreational activities and quality of life. This study evaluated frequency, location, and extent of associated injuries in patients with recurrent patellar dislocation.

Methods
This systematic review was conducted according to the PRISMA checklist. PubMed, Google scholar, Embase, and Web of Science databases were accessed in July 2021. All the published clinical studies reporting frequency, location, and extent of soft tissue lesions in patients with recurrent patellar dislocations were accessed.

Results
Data from 9 articles (232 patients) were retrieved. The mean age of the included patients was 21.2 ± 5.6 years. 84.8% of patients suffering from recurrent patellar dislocations demonstrated patellar chondral defects: medial facet (34.9%), while patellar crest (34.8%) and lateral facet (17%). 27.8% of patients demonstrated trochlear chondral injuries.

Conclusion
Chondral defects of the medial facet and the crest of the patella are the most common in patients with recurrent patellofemoral instability.

Abstract
Background
With more than 3.6 million Syrian refugees Turkey hosts the world's largest number of Syrians. Considering the morbidity, mortality, and healthcare spending, cancer is one of the leading health and economic burden for patients and healthcare systems. However, very limited information available in the scientific literature to understand the burden and characteristics of cancer in countries hosting Syrian refugees. The aim of the present study is to evaluate the demographic and clinical characteristics, treatment outcome of Syrian cancer patients living in Konya, Turkey.

Methods
We retrospectively reviewed medical records of Syrian cancer patients at three major institutions from 2005 to 2020. The information regarding demographic and clinical characteristics of patients were identified. The number of days between the first symptom and diagnosis was considered as the “diagnostic interval”. Patients who failed to attend clinics within four weeks of appointment were assumed abandoned treatment. Survival curves were estimated using the Kaplan–Meier method.

Results
We identified 230 adult and 38 children refugee diagnosed with cancer during the study period. With regards to adult patients, there were 114 (49.6%) male and 116 (50.4%) female. The median age at diagnosis was 52.4, 47.3 years for male, female respectively. The five most common cancer by site among all were; breast (24.8%), colorectal (10.9%), lung (7.4%), central nervous system (CNS) (7.0%), and stomach (5.2%). 93 (40.4%) had metastatic disease at diagnosis. The overall survival probability was 37.5% at five years for the adult population. Data were extracted for 20 boys and 18 girls with childhood cancer. Their median age at diagnosis was 5.8 and 6.0 years respectively. The three most common childhood cancer were; leukemias (21.1%), lymphomas (21.1%), and CNS (13.2%). Excluding leukemia, 13 (43.3%) of childhood cancer cases had the advanced disease at diagnosis. Three year survival probality was 69.5%. The median diagnostic interval for adult and childhood cancer was 96.5 (IQR = 53–165) and 23 (IQR = 13.5–59) days respectively. Twenty-one adults and four children had treatment abandonment.

Conclusion
This study contributes to understanding the burden of cancer among Syrian refugees living in Konya, growing health issue for refugees. Larger and prospective studies will help to measure the real burden and compare the difference in cancer risk factors, care, and outcomes among the refugee and host populations.
