SummaryAdequate sleep has been positively related with health and school achievement outcomes during adolescence. The aim of this study was to investigate the associations of objectively measured and self‐reported sleep duration and quality with academic and cognitive performance in adolescents. This study was conducted with 257 adolescents (13.9 ± 0.3 years) from the DADOS study (Deporte, ADOlescencia y Salud). Objectively measured and self‐reported sleep duration and quality were obtained by a wrist‐worn GENEActiv accelerometer and the Spanish version of Pittsburgh Sleep Quality Index questionnaire, respectively. Academic performance was analysed through school records using four indicators: math, language, science and grade point average score. Cognitive performance was measured using the Spanish version of the “SRA Test of Educational Ability”. After Benjamini–Hochberg correction for the false discovery rate, objectively measured sleep duration was negatively associated with verbal ability (β = −0.179, p = .004), whilst self‐reported sleep quality was positively associated with academic performance (β ranging from 0.209 to 0.273; all p < .001). These associations remained significant after further controlling for physical fitness and physical activity. Conversely, there were no associations between self‐reported sleep duration and objective sleep quality with academic and cognitive performance. Our findings fit in line with previous research showing that sleep quality may play an important role on adolescents’ academic performance. Further interventional research is needed to clarify the mechanisms by which sleep is related to academic performance in youth.

ObjectivesTo assess the association between postoperative cystogram findings and subsequent outcomes on urinary continence after robot‐assisted laparoscopic radical prostatectomy (RALP).MethodsA retrospective review of 250 consecutive patients who were observed for at least 12 months after RALP. The postoperative cystogram findings examined were: the location of the bladder neck, degree of bladder abnormalities, and presence of outflow of contrast medium into the urethra during the filling phase of cystography. The continence status based on pad usage was recorded. Those who required no pad or only a safety pad were defined as continent.ResultsPatients with a bladder neck location above the middle of the pubic symphysis height exhibited significantly higher continence levels than those with a lower bladder neck location at both postoperative 3 and 12 months (P < 0.0001 and P = 0.0002, respectively). The higher a bladder neck was located, the earlier the urinary continence was achieved after RALP (P < 0.0001). Patients without contrast outflow into the urethra during cystogram demonstrated a significantly more favorable continence status at the 3‐month follow‐up (P = 0.004). Patients without bladder abnormalities on postoperative cystogram demonstrated a significantly more favorable continence status at the 12‐month follow‐up than those with bladder abnormalities (P = 0.01).ConclusionsPostoperative cystogram findings may predict recovery of urinary continence after RALP.
Optimal harvesting of a renewable resource in a polluted environment: An allocation problem of the sole owner
Authors: Pichika Srinivasu D. N. , Zawka Simon D. 
Published: January 2019

AbstractThis study presents an allocation problem of the sole owner between a renewable resource harvesting and pollution reduction. Decline in the revenues due to the presence of pollution in the environment drives the harvester to allocate a part of the available effort capacity towards pollution reduction through environmental treatment and pollutant inflow reduction to improve the resource growth as well as quality of the harvest. Hence, the interest is to find an optimal effort allocation to maximize the present value of the total net revenues on infinite horizon. Therefore, an optimal harvest problem on infinite horizon has been formulated, and it is solved using the standard techniques of optimal control. Results of the study highlight that allocating a part of the available effort capacity towards pollution reduction improves not only the revenue from the harvest but also survival rate of the resource. Key results of the study are demonstrated through numerical simulations.Recommendations for Resource Managers

Effect of pollution on the live stock is adverse, and it should be considered as one of the important parameters in resource management objectives. The presence of pollution in the environment affects both the resource growth and quality of biomass, resulting in reduced revenue from the harvest.
Pollution is inevitable (especially in developing countries), and hence investing a part of the available effort capacity on pollution reduction (instead of harvesting by the entire capacity) can be considered as an alternative to improve the revenue.
Environmental treatment and pollutant inflow reduction are some of the activities that can be applied to reduce pollution.
Results of this study provide an important information for the sole owner who faces a decline in the revenue from resource harvesting in a polluted environment.
Resilience and finances on Aotearoa New Zealand farms: Evidence from a random survey on the sources and uses of debt
Authors: Greig Bruce , Nuthall Peter , Old Kevin 
Published: January 2019

AbstractDebt and income are keystones to financial resilience on New Zealand farms. This article utilises a survey on finance to assess farm financial health using a new model of resilience. It shows the majority of farms are financially strong. Further borrowing and development are possible. With increasing variability resulting from the longer term trade liberalisation as well as global warming impacts, the high equity will provide future resilience. On the other hand, profit levels are not high relative to the investment, but this has been the case for decades and has not caused problems due to farmer and farm family resilience.

Published: January 2019

SummaryLifestyle interventions addressing diet, exercise‐training, sleep hygiene, and/or tobacco/alcohol cessation are recommended in the management of obstructive sleep apnoea (OSA). Yet their effectiveness on this condition still requires further research. This systematic review and meta‐analysis was aimed at establishing (a) the effectiveness of lifestyle interventions on apnoea‐hypopnoea index (AHI), oxygen desaturation index (ODI), excessive daytime sleepiness (EDS), and secondary OSA measures among adults, and (b) which intervention characteristics may drive the greatest improvements. A systematic search of studies was conducted using CINAHL, ProQuest, Psicodoc, Scopus, and Web of Science, from inception to April 2018. Standardized mean differences were calculated using the inverse variance method and random‐effects models. The meta‐analyses of 13 randomized controlled trials and 22 uncontrolled before‐and‐after studies (1420 participants) revealed significant reductions on AHI (d = −0.61 and −0.46, respectively), ODI (d = −0.61 and −0.46) and EDS (d = −0.41 and −0.49). Secondary OSA outcomes were also improved after interventions. However, effectiveness of interventions differed depending on their components, OSA severity, and gender. Thus, until future research further supports the differential effectiveness among lifestyle interventions on OSA, those addressing weight loss through diet and exercise‐training may be the most effective treatments for male patients with moderate‐severe OSA.

AbstractIntroductionSeveral clinical studies have demonstrated that remote monitoring (RM) offers potential benefits in transvenous implantable cardioverter defibrillator (ICD). The potential interest of RM in subcutaneous‐ICD (S‐ICD) recipients has never been evaluated. The aim of this study was to evaluate the alert burden and its clinical relevance in a prospective cohort of S‐ICD recipients.MethodsWe prospectively and consecutively enrolled all patients undergoing S‐ICD implantation at Lille University Hospital from September 2015 to January 2017 and gave them a LATITUDE™ NXT RM system. The relevance of transmissions was assessed by the following ratio: number of transmissions leading to reaction or intervention per patient/number of transmissions per patient.ResultsFrom September 2015 to January 2017, 69 patients were enrolled with a mean follow‐up of 415 ± 96.3 days. The mean age was 44.6 ± 15.6 years old, and 25% (n = 17) had ischemic cardiomyopathy. At the end of follow‐up, 12% of the patients had events recorded by RM. These events were related to nine ICD shocks and eight untreated events. A total of 1,423 transmissions were collected. Most of these transmissions were patient‐initiated without any event (77%, n = 1,096) or scheduled without any event (19%, n = 272). Only 3.2% ± 1.1 of the transmissions per patient led to reactions or interventions.ConclusionOn the basis of the current method of transmitting, S‐ICD RM allowed detection of relevant events in 12% of patients but generated a high unactionable transmission burden. As a result of these findings, efforts should be made to optimize transmissions considering automatic transmissions and to focus on patient education.

AbstractMany stem rust resistance genes have been formally named in wheat. Adult plant stem rust resistance gene Sr2 was mapped in the short‐arm of chromosome 3B. Stripe rust resistance gene Yr57, identified in Aus91463, was mapped about 5 cM away from Sr2 based on its linkage with Sr2‐linked marker gwm533. The objective of this study was to combine Sr2 and Yr57 in a single genotype. A mapping population containing 107 recombinant inbred lines was developed from a cross between Aus91463‐Yr57 and Hartog‐Sr2. This population was tested at the seedling stage in the glasshouse for variation in stripe rust response, and high temperature induced Sr2‐linked seedling chlorosis. The RIL population was screened for Sr2‐linked pseudo black chaff phenotype at the adult plant stage in field. Five recombinants carrying Sr2 and Yr57 in coupling were detected using phenotypic and marker data. Four recombinants also carried leaf rust resistance gene Lr23 from Aus91463. These recombinants are being used as triple rust resistance source in the Australian Cereal Rust Control Program.
The Behaviour of Banking Stocks During the Financial Crisis and Recessions. Evidence from Changes‐in‐Changes Panel Data Estimations
Authors: Asteriou Dimitrios , Pilbeam Keith , Sarantidis Antonios 
Published: January 2019

AbstractThis paper examines the impact of the financial crisis and economic recessions on bank shares compared to the overall stock market index for 18 OECD countries from 1993 to 2015. The empirical methodology utilizes the changes‐in‐changes approach. We compare and contrast the returns of the banking stock price index (treatment group) in each country with their general stock price index (control group), which experiences smaller changes. Our results suggest that bank returns on average perform significantly worse than that of the general stock price index during recessions. In addition, we also find significantly greater volatility in bank share returns.

Published: January 2019

AbstractBackgroundGlutaraldehyde cross‐linked bioprosthetic heart valves might fail due to progressive degradation and calcification.MethodsIn this study, we developed a new BHVs preparation strategy named as “HPA/TRA/FMN” that utilized 3,4‐hydroxyphenylpropionic acid (HPA)/tyramine (TRA) conjugated pericardium and riboflavin 5’‐monophosphate (FMN) initiated photo‐cross‐linking method. HPA/TRA‐pericardium conjugation would provide extra phenol groups for FMN initiated photo‐cross‐linking.ResultsThe feeding ratio of riboflavin 5’‐monophosphate was optimized. The collagenase and elastase enzymatic degradation in vitro, biomechanics, calcification, elastin stability in vivo, and macrophage marker CD68 were characterized. We demonstrated that riboflavin photo‐cross‐linked pericardiums had great collagen and elastin stability, improved mechanical properties, better resistance for calcification, and less CD68 positive macrophages in rat subdermal implantation study.ConclusionsThis new riboflavin photo‐cross‐linking strategy would be a promising method to make BHVs which have better elastin stability, less calcification, and reduced inflammatory response.

ObjectivesTo explore and describe the experiences and perspectives of collecting and storing colostrum in the antenatal period in women who have had diabetes in pregnancy.DesignFace-to-face, semistructured interviews analysed with purposive sampling and thematic analysis.SettingA regional hospital in North Queensland with a high prevalence of diabetes in pregnancy.ParticipantsSix women with a previous pregnancy complicated by diabetes who were advised to collect and store colostrum in pregnancy.ResultsSix themes were identified: wariness of medicalisation (adjusting to an ‘abnormal’ pregnancy, seeking continuity of care, determination to reduce formula, fear of invasive intervention); underlying altruism (providing the best for baby, preparing for complications, eager for milk donation); internal pressure to succeed (coping with confronting information, disheartened by failures, constant fear of insufficient supply, overwhelming guilt, concern for future breastfeeding success); self-management and ownership (adapting to awkwardness, developing strategies for success, actively seeking education, gaining confidence to request help, accepting personal limitations); frustrated by waste (encroaching on time, squandering a precious resource, ambiguous about necessity) and building fortitude for motherhood (physically preparing for breast feeding, symbolic of the imminent infant, establishing early relationships with supports, approaching challenges with realistic optimism).ConclusionWomen with diabetes in pregnancy experience guilt and stress about the added risk of hypoglycaemia to their babies and strive to provide the best for their babies by collecting and storing colostrum, even if this leads to distress to themselves. It is crucial that these women be provided accurate, realistic advice about the benefits and disadvantages of collecting colostrum in the antenatal period.

ObjectiveTo compare the prevalence of depression, anxiety and comorbidity between HIV-negative men who have sex with men and women (MSMW) and men who have sex with men only (MSMO) and examine the associated factors with depression and anxiety separately.DesignA cross-sectional study.SettingThe study was conducted in Western China.ParticipantsFrom April 2013 to October 2014, 2422 participants aged 18–65 years, who were male at birth, had engaged in sex with male partners in the past 6 months, self-reported negative or unknown HIV status, were willing to participate and provided informed consent were recruited using non-probability sampling. An anonymous self-administered questionnaire was used to collect the data. A total of 1809 HIV-negative men who have sex with men (MSM) were eligible for the final analysis.ResultsOf 1809 MSM, 16.1% were MSMW and 83.9% were MSMO. The prevalence of depression, anxiety and comorbidity was 50.86%, 36.43% and 32.65%, respectively, for MSMW; these results were higher than those for MSMO (35.18%, 23.52% and 18.91%, respectively). After adjusting for potential confounding factors, the prevalence of depression and anxiety was higher among MSMW than among MSMO. The prevalence of depression and/or anxiety was associated with young age, lower educational level, lower monthly income, lower HIV score and some risky sexual behaviour (had never engaged in HIV counselling, had obtained commercial sexual services in the past 6 months and sometimes/always looked for sexual partners through the internet). The prevalence of depression and anxiety was lower for those who drank less than once a week than for those who never drank.ConclusionOur findings suggest the need to address mental health among MSMW. Future health intervention strategies should integrate mental health services and traditional HIV prevention programmes and should consider the differences between MSMW and MSMO.Trial registration numberChiCTR-TRC-13003849; Pre-results.

ObjectiveThis study aimed to establish the first global health bachelor curriculum in China.DesignThe Delphi methodology was used to determine expert consensus on which courses should be included in the global health bachelor curriculum. A literature review and a workshop proceeding were performed to generate courses. Then a two-round Delphi process was conducted with 28 invited experts from universities, health administrative departments and non-governmental organisations to rate courses using a 5-point Likert scale. Additionally, the experts could alter, add or delete courses as appropriate. Consensus was predefined as a mean score of 4 or above and the percent agreement (proportion of panel members scoring ‘very important’ or ‘important’) no less than 75%.ResultsThe responses in the two-round Delphi process were 85.7% and 70.8%, respectively. In the first round, 12 courses did not meet the inclusion criteria and were removed. Based on the participants’ comments, 32 courses were included in round 2. In the second round, the consensus was reached on 31 courses which were selected as the final curriculum. These courses were categorised into five modules, including General Knowledge, Methodology, Global Health Issues, Intercultural Communication, and Health Policy and Programme Management.ConclusionThis study established the first global health bachelor curriculum in China. It will provide guidance for other educational institutions to develop similar programmes or curricula in the future.

AimTo present the protocol of a systematic review and meta-analysis of the available evidence examining the association between sex hormones and type 2 diabetes risk in ageing men and women of African descent.MethodsWe shall conduct a comprehensive search of published studies that examined the association between sex hormones and type 2 diabetes risk in men and women aged ≥40 years from 01/01/1980 to 31/03/2018 with no language restriction. Databases to be searched include: PubMed, Scopus, Cochrane Library, Cumulative Index to Nursing and Allied Health, ISI Web of Science, Clinical Trial registries, Google Scholar and institutional websites such as the WHO, American Diabetes Association, International Diabetes Federation, World Diabetes Foundation, European Association for the Study of Diabetes, African Journal Online and ProQuest databases. This protocol is developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. Independent screening for eligible studies using defined criteria and data extraction, will be completed in duplicate. Discrepancies will be resolved by consensus or consultation with a third researcher. Risk of bias of included studies will be assessed by the appropriate Cochrane risk of bias tool. The overall association estimates will be pooled using appropriate meta-analytic techniques. Heterogeneity will be assessed using Cochrane Q statistic and the inconsistency index (I2). The random effects model will be used to calculate a pooled estimate.Ethics and disseminationNo ethics clearance is required as no primary data will be collected. The systematic review and meta-analysis are part of a PhD project at WITS University (Johannesburg, South Africa) and results will be presented at conferences and published in a peer-review journal. The results will guide future population specific interventions.PROSPERO registration numberCRD42017074581.
