SummaryXinjiang has been the largest and highest yield cotton production region not only in China, but also in the world. Improvements in Upland cotton cultivars in Xinjiang have occurred via pedigree selection and/or crossing of elite alleles from the former Soviet Union and other cotton producing regions of China. But it is unclear how genomic constitutions from foundation parents have been selected and inherited. Here, we deep‐sequenced seven historic foundation parents, comprising four cultivars introduced from the former Soviet Union (108Ф, C1470, 611Б and KK1543) and three from United States and Africa (DPL15, STV2B and UGDM), and re‐sequenced sixty‐nine Xinjiang modern cultivars. Phylogenetic analysis of more than 2 million high‐quality single nucleotide polymorphisms allowed their classification two groups, suggesting that Xinjiang Upland cotton cultivars were not only spawned from 108Ф, C1470, 611Б and KK1543, but also had a close kinship with DPL15, STV2B and UGDM. Notably, identity‐by‐descent (IBD) tracking demonstrated that the former Soviet Union cultivars have made a huge contribution to modern cultivar improvement in Xinjiang. A total of 156 selective sweeps were identified. Among them, apoptosis‐antagonizing transcription factor gene (GhAATF1) and mitochondrial transcription termination factor family protein gene (GhmTERF1) were highly involved in the determination of lint percentage. Additionally, the auxin response factor gene (GhARF3) located in inherited IBD segments from 108Ф and 611Б was highly correlated with fibre quality. These results provide an insight into the genomics of artificial selection for improving cotton production and facilitate next‐generation precision breeding of cotton and other crops.
Estimating the Screening-Eligible Population Size, Ages 45–74, at Average Risk to Develop Colorectal Cancer in the United States
Authors: Piscitello Andrew , Edwards David K. 
Published: February 2020

Abstract
Colorectal cancer is a growing burden in adults less than 50 years old. In 2018, the American Cancer Society published a guideline update recommending a reduction in the colorectal cancer screening start age for average-risk individuals from 50 to 45. Implementing these recommendations would have important implications for public health. However, the approximate number of people impacted by this change, the average-risk population ages 45–49, is not well-described in the literature. Here, we provide methodology to conservatively estimate the average-risk and screening-eligible population in the United States, including those who would be impacted by a lowered colorectal cancer screening start age. Using multiple data sources, we estimated the current average-risk population by subtracting individuals with symptomatic colorectal cancer, with a family history of colorectal cancer, and with inflammatory bowel disease and hereditary nonpolyposis colorectal cancer from the total population. Within this population, we estimated the number of screening-eligible individuals by subtracting those with previous colorectal cancer screening (45- to 49-year-old) or up to date with colorectal cancer screening (50- to 74-year-old). The total average-risk population is estimated between 102.1 and 106.5 million people, of whom 43.4–45.2 million people are eligible for colorectal cancer screening. Lowering the screening age would add roughly 19 million people to the average-risk population and increase the current number of screening-eligible individuals on immediate implementation by over 60% (from 27 to 44 million). Estimating the population size impacted by lowering the recommended colorectal cancer screening start age enables more accurate decision-making for policymakers and epidemiologists focused on cancer prevention.

Published: February 2020

Background:
To compare mortality after treatment of superficial femoral-popliteal artery disease with paclitaxel and nonpaclitaxel devices using a multicenter vascular registry.

Methods:
Patients (N=8376) undergoing endovascular treatment of superficial femoral-popliteal artery disease in the Society for Vascular Surgery Vascular Quality Initiative were studied from October 2016 to December 2017. One-year mortality was compared between 3 groups; plain balloon angioplasty (N=2104) versus paclitaxel-coated balloon angioplasty (N=3543), bare-metal stenting (N= 2045) versus paclitaxel-eluting stents (N=684), and combined paclitaxel versus nonpaclitaxel devices. Mortality rates with hazard ratios (HR) and 95% CI were compared in unadjusted and propensity-matched cohorts and illustrated by Kaplan-Meier analysis with subgroup analysis for intermittent claudication, chronic limb-threatening ischemia, and secondary interventions.

Results:

In propensity-matched analyses, mortality was similar after plain balloon angioplasty (12.6%) and paclitaxel-coated balloon angioplasty (9.6%; HR=0.84 [95% CI, 0.66–1.06],
P
=0.14). In propensity-matched groups, mortality was similar after bare-metal stenting (9.8%) and paclitaxel-eluting stenting (8.8%; HR=0.93 [95% CI, 0.62–1.41],
P
=0.75). In the combined, matched analysis mortality was significantly lower in the paclitaxel device group (8.5%) compared with the nonpaclitaxel device group (11.5%; HR=0.82 [95% CI, 0.68–0.98],
P
=0.03). Secondary interventions were similar after nonpaclitaxel (N=1113/4149, 26.8%) and paclitaxel device use (N=1113/4227, 26.3%). For intermittent claudication, mortality was lower after paclitaxel device use (1.6%) compared with nonpaclitaxel devices (4.4%; adjusted HR=0.59 [95% CI, 0.39–0.89],
P
=0.01). For chronic limb-threatening ischemia, the mortality difference was not significant; paclitaxel (12.8%) versus nonpaclitaxel devices (15.5%; adjusted HR=0.85 [95% CI, 0.72–1.00],
P
=0.05).

Conclusions:
At 1 year, mortality was similar if not lower after treatment of femoral-popliteal occlusive disease with paclitaxel versus nonpaclitaxel devices. This work highlights the potential use of the Society for Vascular Surgery Vascular Quality Initiative for surveillance of the safety of new peripheral arterial devices.
Developing an integrated emergency medical services in a low-income country like Nepal: a concept paper
Authors: Bhandari Deepak , Yadav Nabin Krishna 
Published: February 2020

Abstract
Background
The main aim of emergency medical services (EMS) should be to provide universal emergency medical care which is EMS system available to all those who need it. Most of the developed countries have an integrated EMS system that is accessible by a single dial number in the whole country. Nepal does not have a proper EMS system. We conducted a literature review regarding methods of developing an integrated EMS system in Nepal.

Result
The fragmented system, high demand–low supply, inequity with the service, and inadequately trained responders are major problems associated with EMS in Nepal. Nepal too should develop an integrated single dial number EMS system to meet the current demand of EMS. Having a paramedic in ambulances as the first responders will prevent chaos and save critical time. Funding models have to be considered while developing an EMS considering the capital as well as operational cost.

Conclusion
Nepal can develop a public private partnership model of EMS where capital cost is provided by the government and operational cost by other methods. Community-based insurance system looks more feasible in a country like Nepal for generating operational cost.
Incorporation of a truncated form of flagellin (TFlg) into porcine circovirus type 2 virus-like particles enhances immune responses in mice
Authors: Liu Xiangyu , Liu Yangkun , Zhang Yuanyuan , Zhang Fan , Du Enqi 
Published: February 2020

Abstract
Background
Porcine circovirus type 2 (PCV2) is an economically important pathogen in the swine industry worldwide. Vaccination remains the principal tool to control PCV2-associated diseases (PCVADs). Current vaccines do not eliminate viral shedding in the environment. To enhance the efficacy of PCV2 vaccines, recombinant virus-like particles (VLPs) of PCV2 were generated by fusing a truncated form of flagellin FliC (TFlg: 85-111aa) with the PCV2 capsid protein (Cap).

Results
The recombinant proteins were expressed in Escherichia coli and detected using Western blotting. The abilities of the recombinant proteins to assemble into VLPs were observed under transmission electron microscopy (TEM). The protective immune responses of recombinant VLPs were further evaluated by immunization of mice. The results showed that insertion of TFlg into C terminal of the Cap protein did not affect the formation of VLPs and boosted both humoral and cellular immune responses in mice. After a challenge with PCV2, in the Cap-TFlg vaccinated group, viremia was milder and viral loads were lower as compared with those in the Cap vaccinated group.

Conclusion
These results suggest that recombinant VLPs of PCV2 containing a TFlg adjuvant can be used as a promising PCV2 vaccine candidate.
The hypoxic microenvironment: a driving force for heterotopic ossification progression
Authors: Huang Yifei , Wang Xinyi , Lin Hui 
Published: February 2020

AbstractHeterotopic ossification (HO) refers to the formation of bone tissue outside the normal skeletal system. According to its pathogenesis, HO is divided into hereditary HO and acquired HO. There currently lack effective approaches for HO prevention or treatment. A deep understanding of its pathogenesis will provide promising strategies to prevent and treat HO. Studies have shown that the hypoxia-adaptive microenvironment generated after trauma is a potent stimulus of HO. The hypoxic microenvironment enhances the stability of hypoxia-inducible factor-1α (HIF-1α), which regulates a complex network including bone morphogenetic proteins (BMPs), vascular endothelial growth factor (VEGF), and neuropilin-1 (NRP-1), which are implicated in the formation of ectopic bone. In this review, we summarize the current understanding of the triggering role and underlying molecular mechanisms of the hypoxic microenvironment in the initiation and progression of HO, focusing mainly on HIF-1 and it's influenced genes BMP, VEGF, and NRP-1. A better understanding of the role of hypoxia in HO unveils novel therapeutic targets for HO that reduce the local hypoxic microenvironment and inhibit HIF-1α activity.
Children’s fear of needle injections: a qualitative study of training sessions for children with rheumatic diseases before home administration
Authors: Sørensen Kari , Skirbekk Helge , Kvarstein Gunnvald , Wøien Hilde 
Published: February 2020

Abstract
Background
Treatment of rheumatic diseases in children often includes long-term needle injections, which represent a risk for refusing medication based on potential needle-fear. How nurses manage children’s fear and pain during the initial educational training session of subcutaneous injections, may affect the management of the subsequent injections in the home settings. The aim of this study was to explore how children expressed fear and pain during these training sessions, and how adults’ communication affected children’s expressed emotions.

Methods
This qualitative explorative study used video observations and short interviews during training sessions in a rheumatic hospital ward. Participants were children between five and fifteen years (n = 8), their parents (n = 11) and nurses (n = 7) in nine training sessions in total. The analysis followed descriptions of thematic analysis and interaction analysis.

Results
The children expressed fears indirectly as cues and nonverbal signs more often than direct statements. Three children stated explicit being afraid or wanting to stop. The children worried about needle-pain, but experienced the stinging pain after the injection more bothersome. The technical instructions were detailed and comprehensive and each nurse shaped the structure of the sessions. Both nurses and parents frequently offered coping strategies unclearly without sufficient time for children to understand. We identified three main adult communication approaches (acknowledging, ambiguous and disregarding) that influenced children’s expressed emotions during the training session.

Conclusions
Children’s expression of fear was likely to be indirectly, and pain was mostly related to the injection rather than the needle stick. When adults used an acknowledging communication and offered sufficient coping strategies, children seemed to become involved in the procedure and acted with confidence. The initial educational training session may have a great impact on long-term repeated injections in a home setting by providing children with confidence at the onset.
Pharmacological conditioning for juvenile idiopathic arthritis: a potential solution to reduce methotrexate intolerance
Authors: Smits Rosanne M. , Veldhuijzen Dieuwke S. , van Middendorp Henriet , Hissink Muller Petra C. E. , Armbrust Wineke , Legger Elizabeth , Wulffraat Nico M. , Evers Andrea W. M. 
Published: February 2020

Abstract
Background
Methotrexate (MTX) therapy has proven to be a successful and safe treatment for Juvenile Idiopathic Arthritis (JIA). Despite the high efficacy rates of MTX, treatment outcomes are often complicated by burdensome gastro-intestinal side effects. Intolerance rates for MTX in children are high (approximately 50%) and thus far no conclusive effective treatment strategies to control for side effects have been found. To address this need, this article proposes an innovative research approach based on pharmacological conditioning, to reduce MTX intolerance.

Presentation of the hypothesis
A collaboration between medical psychologists, pediatric rheumatologists, pharmacologists and patient groups was set up to develop an innovative research design that may be implemented to study potential improved control of side effects in JIA, by making use of the psychobiological principles of pharmacological conditioning. In pharmacological conditioning designs, learned positive associations from drug therapies (conditioning effects) are integrated in regular treatment regimens to maximize treatment outcomes. Medication regimens with immunosuppressant drugs that made use of pharmacological conditioning principles have been shown to lead to optimized therapeutic effects with reduced drug dosing, which might ultimately cause a reduction in side effects.

Testing the hypothesis
This research design is tailored to serve the needs of the JIA patient group. We developed a research design in collaboration with an interdisciplinary research group consisting of patient representatives, pediatric rheumatologists, pharmacologists, and medical psychologists.

Implications of the hypothesis
Based on previous experimental and clinical findings of pharmacological conditioning with immune responses, we propose that the JIA patient group is particularly suited to benefit from a pharmacological conditioning design. Moreover, findings from this study may potentially also be promising for other patient groups that endure long-lasting drug therapies.

Abstract
Objectives
For migrant female sex workers (FSWs) at the Sino-Vietnamese border, the impact of work time in their current location on the spread of HIV/AIDS is not clear.

Methods
Data were collected from the Sino-Vietnamese border cities of Guangxi, China. Migrant FSWs working in these cities were studied. FSWs who worked less than 6 months in their current location were assigned to the short-term work group (ST FSWs), and FSWs who worked equal to or longer than 6 months in their current location were assigned to the long-term work group (LT FSWs). Logistic regression was performed to examine the impact of work time in the current location and factors associated with HIV infection.

Results
Among the 1667 migrant FSWs, 586 (35.2%) and 1081 (64.9%) were assigned to the ST FSW and LT FSW groups, respectively. Compared to LT FSWs, ST FSWs were more likely to be of Vietnamese nationality, be less than 18 years old when they first engaged in commercial sex work, and have a low-level of HIV-related knowledge and had higher odds of using condoms inconsistently, having more male clients, having no regular male clients, and having a history of male clients who used aphrodisiacs but lower odds of receiving free condoms distribution and education/HIV counselling and testing programme. The analysis of factors associated with HIV infection revealed that Vietnamese FSWs, less than 18 years old when they first engaged in commercial sex work, having no regular male clients, and having lower average charge per sex transaction were correlated with HIV infection.

Conclusion
FSWs with short-term work at the Sino-Vietnamese border had a higher risk of risky sex and were correlated with HIV risk factors. Vietnamese FSWs were at higher risk of HIV infection, and they were more likely to have short-term work. More targeted HIV prevention should be designed for new FSWs who recently began working in a locality to further control the spread of HIV, particularly cross-border FSWs.
Effectiveness of Checklist-Based Box System Interventions (CBBSI) versus routine care on improving utilization of maternal health services in Northwest Ethiopia: study protocol for a cluster randomized controlled trial
Authors: Andargie Netsanet Belete , Jebena Mulusew Gerbaba , Debelew Gurmesa Tura 
Published: February 2020

Abstract
Background
Maternal mortality is still high in Ethiopia. Antenatal care, the use of skilled delivery and postnatal care are key maternal health care services that can significantly reduce maternal mortality. However, in low- and middle-income countries, including Ethiopia, utilization of these key services is limited, and preventive, promotive and curative services are not provided as per the recommendations. The aim of this study is to examine the effectiveness of checklist-based box system interventions on improving maternal health service utilization.

Methods
A community-level, cluster-randomized controlled trial will be conducted to compare the effectiveness of checklist-based box system interventions over the routine standard of care as a control arm. The intervention will use a health-extension program provided by health extension workers and midwives using a special type of health education scheduling box placed at health posts and a service utilization monitoring box placed at health centers. For this, 1200 pregnant mothers at below 16 weeks of gestation will be recruited from 30 clusters. Suspected pregnant mothers will be identified through a community survey and linked to the nearby health center. With effective communication between health centers and health posts, dropout-tracing mechanisms are implemented to help mothers resume service utilization. Data will be collected using an open data kit and analyzed using STATA version 13.0. Data will be analyzed by the intention-to-treat analysis. Risk ratios will be computed at the cluster level and the summary will be compared using t tests. Outcomes between intervention and control groups will be compared with random effects logistic regression models. Achieving four antenatal care visits, health facility delivery, and postnatal care visits at 6 weeks after delivery were treated as primary outcomes for this study.

Discussion
We expect that the study will generate evidence on the effectiveness of checklist-based box system interventions on improving utilization of maternal health care service that will produce inputs for related policies in Ethiopia.

The effects of protective lung ventilation on regional cerebral oxygen saturation in intracranial tumor operation during dura opening: study protocol for a randomized controlled trial
Authors: Li Jinlu , Wu Xuemei , Liu Hairui , Huang Ying , Liu Yueqin , Xie Hong , Dong Jun 
Published: February 2020

Abstract
Objective
The objective of this trial is to investigate the effects of protective lung ventilation on regional cerebral oxygen saturation (rSO2) during dura opening, that is from Ta (after dura opening) to Tb (before dura closing), in patients undergoing intracranial tumor surgery.

Methods
This is a randomized controlled trial which will be carried out at the Second Affiliated Hospital of Soochow University. Fifty-four patients undergoing intracranial tumor surgery will be randomly allocated to the control group (C group) or the protective lung ventilation group (P group). In the C group, the tidal volume (VT) will be set at 8 ml/kg of predicted body weight, but positive end-expiratory pressure (PEEP) and recruitment maneuvers will not be used. In the P group, VT will be set at 6 ml/kg of predicted body weight combined with individualized PEEP during dura opening, while in other periods of general anesthesia, VT will be set at 8 ml/kg of predicted body weight. The level of rSO2, partial pressures of oxygen and carbon dioxide, oxygenation index, lactic acid level in arterial blood, and mean arterial pressure will be compared before anesthesia (T0), before dura opening (T1), after dura closing (T2), and 24 h after surgery (T3). Lung ultrasound scores will be measured at T0 and T3. The degree of brain relaxation at T1 and T2 will be evaluated by the surgeon using the brain relaxation scale. The amount of vasoactive drugs used and blood loss will be recorded during surgery. The duration of operation and reoperation rate will be recorded. The primary outcome of this study is the changes in rSO2 within 24 h postoperatively.

Discussion
This study aims to determine whether protective lung ventilation during dura opening can improve rSO2 and the state of pulmonary ventilation in patients undergoing intracranial tumor surgery, and to investigate whether this strategy affects the degree of brain tissue swelling and the reoperation rate after operation. If our results are positive, this study will show that protective lung ventilation during dura opening can be used effectively and safely in neurosurgical patients undergoing craniotomy for tumor resection.
