Published: December 2020

AbstractBackgroundA host of researches have demonstrated the regulation of long non-coding RNAs (lncRNAs) in the progression of pancreatic cancers (PC). In this study, our main task was to analyze the function of MAF bZIP transcription factor G antisense RNA 1 (MAFG-AS1) in PC.MethodsRT-qPCR measured gene expression. Functional experiments, including EdU assay, flow cytometry analysis, TUNEL assay and transwell assay, assessed the biological changes of PC cells. RNA pull down assay, luciferase reporter assay and RIP assay verified the interaction between RNAs.ResultsMAFG-AS1 was lowly expressed in normal pancreatic samples but up-regulated in PC tissues and cell lines. Besides, MAFG-AS1 silence suppressed cell proliferation and migration whereas promoted cell apoptosis in PC. Mechanism assays verified that miR-3196 could bind with MAFG-AS1. Moreover, miR-3196 was discovered to be lowly expressed in PC cell lines, and its overexpression inhibited PC cell growth and migration. Importantly, nuclear factor I X (NFIX), overexpressed in PC cell lines, was validated to be positively modulated by MAFG-AS1 through absorbing miR-3196. Moreover, overexpression of NFIX could countervail the restraining effects of MAFG-AS1 knockdown on the growth and migration of PC cells.ConclusionMAFG-AS1 had an oncogenic function in the progression of PC via regulating miR-3196/NFIX pathway, and decreasing MAFG-AS1 expression could attenuate PC progression.

Authors: Liu Jian , Li Kai , Wang Rui , Chen Sisi , Wu Jie , Li Xiang , Ning Qian , Yang Ganghua , Pang Yamei 
Published: December 2020

Abstract
Background
Activating transcription factor 2 (ATF2), a member of the activator protein 1 (AP-1) transcription factor family, has been shown to be involved in the pathobiology of numerous cancers. However, the biological role and mechanism of ATF2 in lung adenocarcinoma (LUAD) remains to be elucidated.

Methods
The expression of ATF2, NEAT1 and miR-26a-5p in LUAD tissues and cell lines was detected by qRT-PCR and western blotting. The interaction between ATF2, NEAT1, and miR-26a-5p was validated by chromatin immunoprecipitation, luciferase reporter assay and RNA immunoprecipitation. Cell proliferation, invasion and tumorigenesis of LUAD cells were analyzed by using CCK8, transwell invasion assay and xenograft tumor model.

Results
We confirmed that ATF2 expression was increased in LUAD tissues compared with normal adjacent lung tissues. Functional experiments showed that ATF2 positively regulated cell proliferation and invasion in LUAD cells. Moreover, we identified that NEAT1 expression was increased in LUAD tissues and positively correlated with ATF2 expression. Mechanistically, ATF2 could bind to the promoter of NEAT1 to promote its transcription. Rescue experiments showed that ATF2 exerted its oncogenic function in LUAD, at least, partly through NEAT1 upregulation. In turn, NEAT1 could positively regulate ATF2 expression and form a positive feedback loop in LUAD cells. Furthermore, we demonstrated that NEAT1 positively regulated ATF2 expression via sponging miR-26a-5p.

Conclusion
ATF2 and NEAT1 form a positive feedback loop mediated by miR-26a-5p and coordinately contribute to LUAD progression.
Social exclusion and universal health coverage: health care rights and citizen-led accountability in Guatemala and Peru
Authors: Samuel Jeannie , Flores Walter , Frisancho Ariel 
Published: December 2020

Abstract
Background
While equity is a central concern in promoting Universal Health Coverage (UHC), the impact of social exclusion on equity in UHC remains underexplored. This paper examines challenges faced by socially excluded populations, with an emphasis on Indigenous peoples, to receive UHC in Latin America. We argue that social exclusion can have negative effects on health systems and can undermine progress towards UHC. We examine two case studies, one in Guatemala and one in Peru, involving citizen-led accountability initiatives that aim to identify and address problems with health care services for socially excluded groups. The case studies reveal how social exclusion can affect equity in UHC.

Methods
In-depth analysis was conducted of all peer reviewed articles published between 2015 and 2019 on the two cases (11 in total), and two non-peer reviewed reports published over the same period. In addition, two of the three authors contributed their first-hand knowledge gathered through practitioner involvement with the citizen-led initiatives examined in the two cases. The analysis sought to identify and compare challenges faced by socially excluded Indigenous populations to receive UHC in the two cases.

Results
Citizen-led accountability initiatives in Guatemala and Peru reveal very similar patterns of serious deficiencies that undermine efforts towards the realization of Universal Health Coverage in both countries. In each case, the socially excluded populations are served by a dysfunctional publicly provided health system marked by gaps and often invisible barriers. The cases suggest that, while funding and social rights to coverage have expanded, marginalized populations in Guatemala and Peru still do not receive either the health care services or the protection against financial hardship promised by health systems in each country. In both cases, the dysfunctional character of the system remains in place, undermining progress towards UHC.

Conclusions
We conclude that efforts to promote UHC cannot stop at increasing health systems financing. In addition, these efforts need to contend with the deeper challenges of democratizing state institutions, including health systems, involved in marginalizing and excluding certain population groups. This includes stronger accountability systems within public institutions. More inclusive accountability mechanisms are an important step in promoting equitable progress towards UHC.

AbstractDuring bloodstream infections, rapid adaptation of empirical treatment according to the microorganism identified is essential to decrease mortality. The aim of the present study was to assess the microbiological performances of a new rapid version of the Sepsityper® kit (Bruker Daltonics) allowing identification of bacteria and yeast by MALDI-TOF mass spectrometry directly from positive blood cultures in 10 min and of the specific MBT-Sepsityper module for spectra analysis, designed to increase identification performance. Identification rates were determined prospectively on 350 bacterial and 29 fungal positive blood cultures, and compared to conventional diagnostic method. Our rapid diagnosis strategy (Rapid Sepsityper® protocol: one spot with and one without formic acid extraction step) combined to MBT-Sepsityper module provided 65.4%, 78.9% and 62% reliable identification to the species level of monomicrobial positive blood cultures growing respectively Gram-positive, Gram-negative bacteria or yeast. Importantly, identification rates of Gram-positive bacteria were higher in anaerobic than in aerobic bottles (77.8% vs 22.2%; p = 0.004), if formic acid extraction step was performed (60.8% vs 39.2%; p = 1.8e−6) and if specific MBT-Sepsityper module was used (76.2% vs 61.9%, p = 0.041) while no significant differences were observed for Gram-negative bacteria. For yeasts identification, formic acid extraction step improved rapid identification rate by 37.9% while the specific MBT-Sepsityper module increased overall performances by 38%, providing up to 89.7% reliable identification if associated with the standard Sepsityper® protocol. These performances, associated with a reduce turnaround time, may help to implement a rapid identification strategy of bloodstream infections in the routine workflow of microbiology laboratories.
An ethical analysis of UK drug policy as an example of a criminal justice approach to drugs: a commentary on the short film Putting UK Drug Policy into Focus
Authors: Holland Adam 
Published: December 2020

Abstract
Background
Drug-related deaths in the UK are at the highest level on record—the war on drugs has failed. A short film has been produced intended for public and professional audiences featuring academics, representatives of advocacy organisations, police and policymakers outlining the problems with, and highlighting alternative approaches to, UK drug policy. A range of ethical arguments are alluded to, which are distilled here in greater depth for interested viewers and a wider professional and academic readership.

Main body
The war on drugs is seemingly driven by the idea that the consumption of illegal drugs is immoral. However, the meaning ascribed to ‘drug’ in the illicit sense encompasses a vast range of substances with different properties that have as much in common with legal drugs as they do with each other. The only property that distinguishes illegal from legal drugs is their legal status, which rather than being based on an assessment of how dangerous they are has been defined by centuries of socio-political idiosyncrasies. The consequences of criminalising people who use drugs often outweigh the risks they face from drug use, and there is not convincing evidence that this prevents wider drug use or drug-related harm. Additionally, punishing someone as a means, to the end of deterring others from drug use, is ethically problematic. Although criminalising the production of harmful drugs may seem more ethically tenable, it has not reduced the supply of drugs and it precludes effective regulation of the market. Other potential policy approaches are highlighted, which would be ethically preferable to existing punitive policy.

Conclusion
It is not possible to eliminate all drug use and associated harms. The current approach is not only ineffective in preventing drug-related harm but itself directly and indirectly causes incalculable harm to those who use drugs and to wider society. For policymakers to gain the mandate to rationalise drug policy, or to be held accountable if they do not, wider engagement with the electorate is required. It is hoped that this film will encourage at least a few to give pause and reflect on how drug policy might be improved.

Abstract
Background
Total endoscopic Ivor-Lewis esophagectomy is a challenging, complex, and costly operation. These disadvantages restrict its wide application. The aim of this study was to compare the modified reverse-puncture anastomotic technique and traditional technique for total minimally invasive Ivor-Lewis esophagectomy.

Methods
In this cohort retrospective study, all patients with medial and lower squamous cell carcinoma of esophagus from February 2014 and June 2018 were divided into two groups according to the surgical method, which were modified reverse-puncture anastomotic technique group and traditional technique group. The operation time, intraoperative bleeding volume, complications, and cost of the two groups were compared.

Results
Forty-eight patients in the modified reverse-puncture anastomotic technique group while 54 patients in the traditional technique group were included. The operation time was 293.4 ± 57.2 min in the modified reverse-puncture anastomotic technique group, which was significantly shorter than that in the traditional technique group (353.4 ± 64.1 min) (P < 0.05). The intraoperative bleeding volume of modified reverse-puncture anastomotic technique group was 157.3 ± 107.4 ml, while it was 191.9 ± 123.6 ml in traditional technique group (P = 0.14). There were similar complications between the two groups. The cost of modified reverse-puncture anastomotic and traditional technique in our hospital were and 72 ± 13 and 83 ± 41 thousand Yuan, respectively (P = 0.08).

Conclusion
The good short-term outcomes that were achieved suggested that the use of modified reverse-puncture anastomotic technique is safe and feasible for total endoscopic Ivor-Lewis esophagectomy.

AbstractAberrant metabolism is the root cause of several serious health issues, creating a huge burden to health and leading to diminished life expectancy. A dysregulated metabolism induces the secretion of several molecules which in turn trigger the inflammatory pathway. Inflammation is the natural reaction of the immune system to a variety of stimuli, such as pathogens, damaged cells, and harmful substances. Metabolically triggered inflammation, also called metaflammation or low-grade chronic inflammation, is the consequence of a synergic interaction between the host and the exposome—a combination of environmental drivers, including diet, lifestyle, pollutants and other factors throughout the life span of an individual. Various levels of chronic inflammation are associated with several lifestyle-related diseases such as diabetes, obesity, metabolic associated fatty liver disease (MAFLD), cancers, cardiovascular disorders (CVDs), autoimmune diseases, and chronic lung diseases. Chronic diseases are a growing concern worldwide, placing a heavy burden on individuals, families, governments, and health-care systems. New strategies are needed to empower communities worldwide to prevent and treat these diseases. Precision medicine provides a model for the next generation of lifestyle modification. This will capitalize on the dynamic interaction between an individual’s biology, lifestyle, behavior, and environment. The aim of precision medicine is to design and improve diagnosis, therapeutics and prognostication through the use of large complex datasets that incorporate individual gene, function, and environmental variations. The implementation of high-performance computing (HPC) and artificial intelligence (AI) can predict risks with greater accuracy based on available multidimensional clinical and biological datasets. AI-powered precision medicine provides clinicians with an opportunity to specifically tailor early interventions to each individual. In this article, we discuss the strengths and limitations of existing and evolving recent, data-driven technologies, such as AI, in preventing, treating and reversing lifestyle-related diseases.

Published: December 2020

Abstract
Background
The aim of this pilot study was to analyze postures during the work of neurologists with respect to their occupational activities.

Methods
A total data material of 64.8 h (3885.74 min) of nine (three m/six f) neurologists (assistant physicians) was collected. Kinematic data were collected using the CUELA system (electro-goniometry). In addition, the occupational tasks performed on-site were subject to a detailed objective activity analysis. All activities were assigned to the categories “Office activities” (I), “Measures on patients” (II) and “Other activities” (III). The angle values of each body region (evaluation parameters) were evaluated according to ergonomic ISO standards.

Results
Only 3.4% of the working hours were spent with (II), while 50.8% of time was spent with (I) and 45.8% with (III). All tasks of category (II) revealed an increased ergonomic risk to the head, neck, trunk and back areas. During category (I) especially neck and back movements in the sagittal plane showed higher ergonomic risk levels.

Conclusion
Despite frequently performed awkward body positions in (II), the ergonomic risk is considered as rather low, since the percentage time share totaled only 3.4%. As a result, “Office activities” have been detected as high predictor to cause stress load on the musculoskeletal system in the daily work of neurologists.
Hyperplastic polyp or sessile serrated lesion? The contribution of serial sections to reclassification
Authors: Jaravaza Diana R. , Rigby Jonathan M. 
Published: December 2020

Abstract
Background
The histological discrimination of hyperplastic polyps from sessile serrated lesions can be difficult. Sessile serrated lesions and hyperplastic polyps are types of serrated polyps which confer different malignancy risks, and surveillance intervals, and are sometimes difficult to discriminate. Our aim was to reclassify previously diagnosed hyperplastic polyps as sessile serrated lesions or confirmed hyperplastic polyps, using additional serial sections.

Methods
Clinicopathological data for all colorectal hyperplastic polyps diagnosed in 2016 and 2017 was collected. The slides were reviewed and classified as hyperplastic polyps, sessile serrated lesion, or other, using current World Health Organization criteria. Eight additional serial sections were performed for the confirmed hyperplastic polyp group and reviewed.

Results
Of an initial 147 hyperplastic polyps from 93 patients, 9 (6.1%) were classified as sessile serrated lesions, 103 as hyperplastic polyps, and 35 as other. Of the 103 confirmed hyperplastic polyps, 7 (6.8%) were proximal, and 8 (7.8%) had a largest fragment size of ≥5 mm and < 10 mm. After 8 additional serial sections, 11 (10.7%) were reclassified as sessile serrated lesions. They were all less than 5 mm and represented 14.3% of proximal polyps and 10.4% of distal polyps. An average of 3.6 serial sections were required for a change in diagnosis.

Conclusion
Histopathological distinction between hyperplastic polyps and sessile serrated lesions remains a challenge. This study has uncovered a potential role for the use of additional serial sections in the morphological reappraisal of small hyperplastic polyps, especially when proximally located.
Barriers and facilitators of implementation of a community cardiovascular disease prevention programme in Mukono and Buikwe districts in Uganda using the Consolidated Framework for Implementation Research
Authors: Ndejjo Rawlance , Wanyenze Rhoda K. , Nuwaha Fred , Bastiaens Hilde , Musinguzi Geofrey 
Published: December 2020

Abstract
Background
In low- and middle-income countries, there is an increasing attention towards community approaches to deal with the growing burden of cardiovascular disease (CVD). However, few studies have explored the implementation processes of such interventions to inform their scale up and sustainability. Using the consolidated framework for implementation research (CFIR), we examined the barriers and facilitators influencing the implementation of a community CVD programme led by community health workers (CHWs) in Mukono and Buikwe districts in Uganda.

Methods
This qualitative study is a process evaluation of an ongoing type II hybrid stepped wedge cluster trial guided by the CFIR. Data for this analysis were collected through regular meetings and focus group discussions (FGDs) conducted during the first cycle (6 months) of intervention implementation. A total of 20 CHWs participated in the implementation programme in 20 villages during the first cycle. Meeting reports and FGD transcripts were analysed following inductive thematic analysis with the aid of Nvivo 12.6 to generate emerging themes and sub-themes and thereafter deductive analysis was used to map themes and sub-themes onto the CFIR domains and constructs.

Results
The barriers to intervention implementation were the complexity of the intervention (complexity), compatibility with community culture (culture), the lack of an enabling environment for behaviour change (patient needs and resources) and mistrust of CHWs by community members (relative priority). In addition, the low community awareness of CVD (tension for change), competing demands (other personal attributes) and unfavourable policies (external policy and incentives) impeded intervention implementation. On the other hand, facilitators of intervention implementation were availability of inputs and protective equipment (design quality and packaging), training of CHWs (Available resources), working with community structures including leaders and groups (process—opinion leaders), frequent support supervision and engagements (process—formally appointed internal implementation leaders) and access to quality health services (process—champions).

Conclusion
Using the CFIR, we identified drivers of implementation success or failure for a community CVD prevention programme in a low-income context. These findings are key to inform the design of impactful, scalable and sustainable CHW programmes for non-communicable diseases prevention and control.

Published: December 2020

Abstract
Background
Stereotactic radiosurgery (SRS) is widely accepted as a therapeutic option for meningiomas (M) and vestibular schwannomas (VS). However, data on outcome and toxicity in the elderly population have rarely been reported in detail.

Methods
All patients aged ≥ 65 years with M or VS who underwent single fraction SRS were included. Patient data were analyzed in terms of clinical tumor control and incidence of early and late treatment related complications, which were graded according to the Common Terminology Criteria for Adverse Events (CTCAE),

Results
We identified 245 patients with benign brain tumors (129 M and 116 VS, median tumor volume 2.9 ml, range 0.1–28). The median age was 71 years (range 65–86) and the mean follow-up times were 42 months (range 2–181). Tumors were irradiated with a median dose of 12.4 Gy. Actuarial clinical and radiological tumor control rates at 2, 5, and 10 years after SRS were 98%, 93%, and 88%, respectively. Recurrent tumors after previous treatment had a higher probability of post-radiosurgical progression (p < 0.001). Permanent toxicity (CTCAE I/II) were noted in 5.7%. No severe adverse events were observed during early and late follow up, although patients > 70 years had a slightly higher risk for toxicity (p = 0.027). The presence and extent of co-morbidities had no significant influence on local tumor control or toxicity.

Conclusion
SRS provides favorable tumor control with low risk for treatment-related severe complications. Thus, SRS should always be considered as treatment option for benign intracranial tumors (meningiomas, schwannomas), especially in the group of elderly patients.
