Published: March 2022

ObjectiveThis study aimed to investigate health-promoting lifestyle status and associated risk factors in patients with polycystic ovary syndrome (PCOS).DesignCross-sectional study.SettingThis study was conducted at a tertiary hospital in Guizhou, China from December 2020 to June 2021.ParticipantsA total of 366 participants (18–45 years) diagnosed with PCOS were recruited from the outpatient departments.MeasuresSociodemographic characteristics were collected, and health-promoting behaviours were measured using the Health-Promoting Lifestyle Profile scale. Anxiety status was measured using the Zung’s Self-Rating Anxiety Scale, depression status using the Zung’s Self-Rating Depression Scale and self-efficacy using the Managing Chronic Disease 6-Item Scale. Multiple stepwise linear regression was conducted to assess the risk factors associated with the health-promoting behaviours of the study participants.ResultsThe participants had a poor health-promoting behaviours (88.54±17.44). The highest score in all dimensions was spiritual growth (16.68±4.98), while physical activity (12.71±2.68) was the lowest. Multiple regression analysis revealed that the main factors influencing the development and maintenance of health-promoting behaviours among participants were education (B=10.788, p<0.001), depression (B=−0.377, p<0.001), anxiety (B=−0.333, p<0.001) and self-efficacy (B=0.938, p=0.002). The model showed 74.40% variance shared between the dependent and independent variables (R2=74.40, F=264.633, p<0.001).ConclusionHealth-promoting behaviours are minimal among patients with PCOS, and improving negative emotions and enhancing behavioural awareness and self-efficacy are necessary to increase the adoption of health-promoting behaviours among patients with PCOS.Trial registration numberChiCTR2000034572.

IntroductionBreast cancer is the most prevalent cancer and the second leading cause of cancer-related deaths among women in low and middle-income countries (LMICs), including sub-Saharan Africa. Mammography screening is the most effective screening method for the early detection of breast cancers in asymptomatic individuals and the only screening test that decreases the risk of breast cancer mortality. Despite the perceived benefits, it has a low utilisation rate in comparison with breast self-examination and clinical breast examination. Several interventions to increase the uptake of mammography have been assessed as well as systematic reviews on mammography uptake. Nonetheless, none of the published systematic reviews focused on women living in LMICs. The review aims to identify interventions that increase mammography screening uptake among women living in LMICs.Methods and analysisRelevant electronic databases will be systematically searched from 1 January 1990 to 30 June 2021 for published and grey literature, including citation and reference list tracking, on studies focusing on interventions to increase mammography screening uptake carried out in LMICs and written in the English language. The search will incorporate the key terms: mammography, interventions, low- and middle-income countries and their associated synonyms. Randomised controlled trials, observational studies and qualitative and mixed methods studies of interventions (carried out with and without comparison groups) reporting interventions to increase mammography screening uptake in LMICs will be identified, data extracted and assessed for methodological quality by two independent reviewers with disagreements to be resolved by consensus or by a third author. We will use narrative synthesis and/or meta-analysis depending on the characteristics of the data.Ethics and disseminationEthical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.PROSPERO registration numberCRD42021269556.

Published: March 2022

IntroductionIntravenous (IV) insertions are among the most performed procedures for children seeking medical care; they are often a painful and stressful experience for both children and their caregivers. Paediatric distress and pain that is inadequately treated may lead to a frightened and uncooperative child, repeated IV attempts and overall frustration with care for both the family and clinical team. We hypothesise that distraction via an immersive virtual reality (VR) experience may reduce the associated distress for children undergoing IV insertions.Methods and analysisThis two-armed randomised controlled superiority trial will be conducted in a Canadian paediatric emergency department and will aim to enrol 80 children overall. Children will be randomised to receive either departmental standard of care alone or standard of care plus an immersive VR experience. Children 6–17 years of age who are undergoing IV insertion and have topical anaesthetic application will be considered for inclusion. Our primary objective is to compare the reduction of distress between the two study arms. The primary outcome will be the child’s observed distress score as measured by the Observational Signs of Behavioral Distress-Revised tool. Secondary outcomes include the child’s pain intensity and fear, parental anxiety, satisfaction with the IV procedure, as well as adverse events. Recruitment launched in September 2020 and is expected to end in March 2022.Ethics and disseminationThis study has been approved by the Health Research Ethics Board (University of Alberta). Informed consent will be obtained from parents or guardians, and assent from children. Study data will be submitted for publication irrespective of results. This study is funded through a Women and Children’s Health Research Institute Innovation grant. Purchase of the VR equipment was facilitated through a Stollery Children’s Hospital Foundation small equipment grant.Trial registration numberNCT04291404Cite Now

IntroductionVery few collaborative nursing care interventions have been studied and shown to be effective in the context of the paradigm shift towards recovery in mental health nursing. Understanding the changes produced in the recovery process of people with mental health problems can contribute to the design and implementation of new methodologies to offer effective and person-centred care.Methods and analysisThis is a mixed-methods study, which is structured in three phases. In phase one (baseline) and phase three (follow-up), quantitative data will be collected from patients at a mental health day hospitals based on a two-armed, parallel-design, non-randomised trial. In phase two, two groups will be established: an intervention group in which the intervention based on collaborative nursing care will be carried out through the codesign and implementation of activities through Participatory Action Research, and a control group in which the usual care dynamics will be continued. All the users of three mental health day hospitals who agree to participate in the study will be studied consecutively until the necessary sample size is reached. The outcomes used to evaluate the impact of the intervention will be the stage of the recovery process, the quality of the therapeutic relationship and the patient’s level of positive mental health.Ethics and disseminationThis study has been approved by the institutional review board of the reference hospital, FIDMAG Hermanas Hospitalarias (PR-2020-10) in July 2020. All participants will be able to voluntarily withdraw from the study at any time. For this reason, users will be given a sheet with all the precise information about the study to be carried out and written consent will be requested. Preliminary and final results will be published in peer-reviewed journals and presented at national and international congresses.Trial registration numberNCT04814576.

Published: March 2022

IntroductionThere has been an increase in the birth prevalence of congenital hypothyroidism (CH) since the introduction of newborn screening, both globally and in the UK. This increase can be accounted for by an increase in CH with gland in situ (CH-GIS). It is not known why CH-GIS is becoming more common, nor how it affects the health, development and learning of children over the long term. Our study will use linked administrative health, education and clinical data to determine risk factors for CH-GIS and describe long-term health and education outcomes for affected children.Methods and analysisWe will construct a birth cohort study based on linked, administrative data to determine what factors have contributed to the increase in the birth prevalence of CH-GIS in the UK. We will also set up a follow-up study of cases and controls to determine the health and education outcomes of children with and without CH-GIS. We will use logistic/multinomial regression models to establish risk factors for CH-GIS. Changes in the prevalence of risk factors over time will help to explain the increase in birth prevalence of CH-GIS. Multivariable generalised linear models or Cox proportional hazards regression models will be used to assess the association between type of CH and school performance or health outcomes.Ethics and disseminationThis study has been approved by the London Queen Square Research Ethics Committee and the Health Research Authority’s Confidentiality Advisory Group CAG. Approvals are also being sought from each data provider. Obtaining approvals from CAG, data providers and information governance bodies have caused considerable delays to the project. Our methods and findings will be published in peer-reviewed journals and presented at academic conferences.

Purpose: To report 24 month safety and efficacy of the Tack Endovascular System for treatment of post-percutaneous transluminal angioplasty (PTA) infrapopliteal dissections in patients with critical limb-threatening ischemia (CLTI). Materials and Methods: The Tack-Optimized Balloon Angioplasty (TOBA) II below-the-knee (BTK) study was a prospective, multicenter, single-arm evaluation of the Tack Endovascular system for post-PTA infrapopliteal dissection repair. Patients with Rutherford Clinical Category (RC) 3 to 5 and a post-PTA dissection(s) of the BTK arteries were enrolled. The 30 day primary safety endpoint was a composite of major adverse limb events (MALE) and all-cause perioperative death (POD). The primary effectiveness endpoint was a composite of MALE at 6 months and 30 day POD. Outcomes were assessed as observational endpoints at 24 months. Results: Tack-Optimized Balloon Angioplasty II BTK enrolled 233 patients; all patients had a post-PTA dissection(s) and received ≥1 Tack implant (range, 1–16). Mean age was 74.4±10.0 years and 67.4% were men. Most patients had CLTI (RC 3: 16.3%; RC 4/5: 83.7%). Mean target lesion length was 80±49 mm. Moderate to severe calcium was present in 89 (35.8%) lesions and total occlusions were present in 118 (47.6%) lesions. Kaplan-Meier freedom from MALE at 24 months + POD at 30 days was 92.2% and 24 month freedom from clinically-driven target lesions revascularization was 73.6%. Kaplan-Meier target limb salvage was 95.7% and amputation-free survival was 75.4%. Improvements in functional status and quality of life were observed through 24 months. Conclusion: The TOBA II BTK study demonstrated sustained safety and efficacy through 24 months in patients treated for post-PTA dissection(s) of BTK lesions.

Published: March 2022

Abstract
Background
With the growing practice of home mechanical ventilation, there is a need to identify biological markers for adequate follow-up. Red cell distribution width (RDW) is a promising candidate because it is convenient, objective and may reflect treatment effect over a long period of time. The aim of this study was to explore the possible role of RDW as a marker for home mechanical ventilation in real-life, unselected chronic respiratory patient populations.

Methods
First, we identified characteristic RDW values for mixed case, unselected chronic respiratory failure and home mechanical ventilated patients through retrospective review within our institutional database. Next, we conducted a prospective observational study to identify RDW changes during the first six months of optimized home mechanical ventilation treatment. Adult patients starting home mechanical ventilation were included. Factors affecting RDW change during the first 6 months of treatment were analysed.

Results
RDW was elevated in both chronic respiratory failure and home mechanical ventilation patients compared to healthy individuals in the retrospective review. In the prospective study of 70 patients, we found that 55.4% of patients starting home mechanical ventilation have abnormal RDW values which are reduced from 14.7 (IQR = 13.2–16.2)% to 13.5 (IQR = 13.1–14.6)% during the first 6 months of HMV treatment (p < 0.001). RDW improvement correlates with improvement in self-reported health-related quality of life and sleepiness scale scores, as well as physical functional status during the same time frame. RDW proved to be a comparable marker to other parameters traditionally used to evaluate treatment efficacy.

Conclusions
RDW is elevated in chronic respiratory failure patients and is significantly reduced in the first six months of optimized home mechanical ventilation. Although further research is needed to verify if RDW change reflects outcome and how comorbidities influence RDW values, our results suggest that RDW is a promising marker of home mechanical ventilation efficacy.

Genetic differentiation of grain, fodder and pod vegetable type cowpeas (Vigna unguiculata L.) identified through single nucleotide polymorphisms from genotyping-by-sequencing
Authors: Wu Xingbo , Cortés Andrés J. , Blair Matthew W. 
Published: March 2022

AbstractThe species Vigna unguiculata L. (Walp), commonly known as cowpea, is a multi-purpose legume that has been selected into three subspecies that are divided into grain, fodder and pod (yardlong bean) types. However, genetic bases for distinctions are not well understood. The purpose of this study was to apply genotyping-by-sequencing (GBS) and current reference genome for V. unguiculata to distinguish three subspecies and identify signatures of divergence. The collection of 130 accessions included 128 cultivated from: 1) ssp. cylindrica, fodder type; 2) ssp. sesquipedalis, pod vegetable type; and 3) ssp. unguiculata, grain type. Two wilds genotypes from spp. dekindtiana and spp. pubescens, were used to anchor phylogeny. A total of 11,083 highly informative single nucleotide polymorphisms (SNPs) were discovered. Wild accessions showed distinct genetic fingerprints and were separated from cultivated subspecies. Principal component analysis showed closer relationship between ssp. unguiculata and ssp. cylindrica compared to ssp. sesquipedalis. Relative differentiation of cultivated subspecies (with Fixation Index, FST) indicated the existence of discrete signatures of selection. This work clarifies the population structure, phylogeny, and domestication of cultivated cowpeas. Furthermore, significant genetic differences between grain and pod vegetable types can provide valuable information for future breeding in three cowpea groups.
The effect of Aloe vera ethanolic extract in preventing ischemic-reperfusion injury during long bone fracture healing after tourniquet application: An animal study
Authors: Huwae Thomas Erwin Christian Junus , Hidayat Mohamad , Sujuti Hidayat , Ratnawati Retty 
Published: March 2022

Background: Tourniquet is a common instrument used in Orthopedics field to reduce blood loss, providing a better operating field. One of the deleterious effects of tourniquet is ischemic-reperfusion injury, which occurs after deflation of the tourniquet. One of the possible ways to mitigate ischemic-reperfusion injury is by administrating antioxidants to reduce oxidative stress. Natural ingredients like Aloe vera are well known for its antioxidant and anti-inflammatory activities. This experimental study was conducted by fracturing the tibia of male Wistar strain rats (Rattus norvegicus) and administering Aloe vera gel orally as antioxidant. Method: A total of 18 rats were used in this study, divided into 6 groups. The first group was the control group, that included rats with fractured tibia not receiving torniquet and aloe vera treatment. The second and third groups were rats with fracture, who received torniquet application for one hour and two hours respectively without aloe vera treatment. The rest were the treatment groups, the rats with factures were given different dosages of Aloe vera extract: 40 mg/kg bodyweight (BW), 60 mg/kg BW, and 80 mg/kg BW. Three hours after administration, the tourniquet was inflated for two hours, followed by its deflation. The tibia was harvested to examine levels of superoxide dismutase (SOD), Malondialdehyde (MDA), and Bone morphogenetic protein 7 (BMP-7), and callus diameter, and osteoblast numbers were evaluated. Result: Administration of Aloe vera extract reduced the oxidative stress parameters (SOD and MDA). Tourniquet application decreased the osteoblast cell count and callus diameter, and administration of Aloe vera extract increased both variables close to the control value (p<0.05). Conclusion: The result of this study suggests that Aloe vera extract could be used to ameliorate ischemic-reperfusion injury.
Sedentary behaviour levels in adults with an intellectual disability: a systematic review and meta-analysis
Authors: Lynch Louise , McCarron Mary , McCallion Philip , Burke Eilish 
Published: March 2022

Background: Sedentary behaviour (SB), which is characterised by low levels of energy expenditure, has been linked to increased cardio-metabolic risks, obesity and mortality, as well as cancer risk. No firm guidelines are established on safe levels of SB. Adults with an intellectual disability (ID) have poorer health than their counterparts in the general population with higher rates of multi-morbidity, inactivity, and obesity. The reasons for this health disparity are unclear however it is known that SB and overall inactivity contribute to poorer health. There is no clear picture of the levels of SB among individuals with ID therefore SB levels in this vulnerable population need to be examined. The aim of this systematic review is to investigate the prevalence of sedentary behaviour in adults with an ID. Methods: The PRISMA-P framework was applied to identify high quality articles. An extensive search was carried out in four databases and grey literature sources . In total, 1,972 articles were retrieved of which 48 articles went forward for full review after duplicate removal and screening by title and abstract. The National Institute of Health’s quality assessment tools were used to assess article quality. Two reviewers independently assessed each article. An excel spreadsheet was created to guide the data extraction process. The final review included 25 articles. A meta-analysis was completed using REVMAN. Results: Different SB assessment types were identified in studies. These included steps, time, questionnaires, and screen time. Studies were heterogeneous. Observed daily steps per individual ranged from 44 to above 30,000, with an average of approximately 6,500 steps. Mean daily time spent in SBs was more than 60% of available time, with observed screen time of more than 3 hours. Conclusion: There is a high prevalence of SB in adults with an intellectual disability. [Registration no: Index CRD42020177225].
Rapidly Evolving Technologies and Startup Exits
Authors: Bowen Donald E. , Frésard Laurent , Hoberg Gerard 
Published: March 2022

This paper examines startups’ positioning within technological cycles. We use patent text to measure whether innovation pertains to a technological area that is rapidly evolving or stable. We show that innovation in rapidly evolving areas (i.e., early in the cycle) substitute for existing technologies, whereas innovation in stable areas (i.e., later in the cycle) complement them. Our new measure is distinct from existing characterizations of innovation and is economically important. We find that startups in rapidly evolving areas tend to exit via initial public offering, thus remaining independent, consistent with technological substitution. In contrast, startups in stable areas tend to sell out, consistent with technological complementarity and synergies. This paper was accepted by Gustavo Manso, finance.
