Tendon and Ligament Injuries in Elite Rugby: The Potential Genetic Influence

This article reviews tendon and ligament injury incidence and severity within elite rugby union and rugby league. Furthermore, it discusses the biological makeup of tendons and ligaments and how genetic variation may influence this and predisposition to injury. Elite rugby has one of the highest reported injury incidences of any professional sport. This is likely due to a combination of well-established injury surveillance systems and the characteristics of the game, whereby high-impact body contact frequently occurs, in addition to the high intensity, multispeed and multidirectional nature of play. Some of the most severe of all these injuries are tendon and ligament/joint (non-bone), and therefore, potentially the most debilitating to a player and playing squad across a season or World Cup competition. The aetiology of these injuries is highly multi-factorial, with a growing body of evidence suggesting that some of the inter-individual variability in injury susceptibility may be due to genetic variation. However, little effort has been devoted to the study of genetic injury traits within rugby athletes. Due to a growing understanding of the molecular characteristics underpinning the aetiology of injury, investigating genetic variation within elite rugby is a viable and worthy proposition. Therefore, we propose several single nucleotide polymorphisms within candidate genes of interest; COL1A1, COL3A1, COL5A1, MIR608, MMP3, TIMP2, VEGFA, NID1 and COLGALT1 warrant further study within elite rugby and other invasion sports.
Risk–Risk Tradeoff Analysis of Nuclear Explosives for Asteroid Deflection

To prevent catastrophic asteroid–Earth collisions, it has been proposed to use nuclear explosives to deflect away earthbound asteroids. However, this policy of nuclear deflection could inadvertently increase the risk of nuclear war and other violent conflict. This article conducts risk–risk tradeoff analysis to assess whether nuclear deflection results in a net increase or decrease in risk. Assuming nonnuclear deflection options are also used, nuclear deflection may only be needed for the largest and most imminent asteroid collisions. These are low‐frequency, high‐severity events. The effect of nuclear deflection on violent conflict risk is more ambiguous due to the complex and dynamic social factors at play. Indeed, it is not clear whether nuclear deflection would cause a net increase or decrease in violent conflict risk. Similarly, this article cannot reach a precise conclusion on the overall risk–risk tradeoff. The value of this article comes less from specific quantitative conclusions and more from providing an analytical framework and a better overall understanding of the policy decision. The article demonstrates the importance of integrated analysis of global risks and the policies to address them, as well as the challenge of quantitative evaluation of complex social processes such as violent conflict.
Individual and combined presenilin 1 and 2 knockouts reveal that both have highly overlapping functions in HEK293T cells

Presenilins 1 and 2 (PS1 and 2) are the catalytic subunits of γ-secretase, a multiprotein protease that cleaves amyloid protein precursor and other type I transmembrane proteins. Previous studies with mouse models or cells have indicated differences in PS1 and PS2 functions. We have recently reported that clinical γ-secretase inhibitors (GSIs), initially developed to manage Alzheimer's disease and now being considered for other therapeutic interventions, are both pharmacologically and functionally distinct. Here, using CRISPR/Cas9-based gene editing, we established human HEK 293T cell lines in which endogenous PS1, PS2, or both have been knocked out. Using these knockout lines to examine differences in PS1- and PS2-mediated cleavage events, we confirmed that PS2 generates more intracellular β-amyloid than does PS1. Moreover, we observed subtle differences in PS1- and PS2-mediated cleavages of select substrates. In exploring the question of whether differences in activity among clinical GSIs could be attributed to differential inhibition of PS1 or PS2, we noted that select GSIs inhibit PS1 and PS2 activities on specific substrates with slightly different potencies. We also found that endoproteolysis of select PS1 FAD-linked variants in human cells is more efficient than what has been previously reported for mouse cell lines. Overall, these results obtained with HEK293T cells suggest that selective PS1 or PS2 inhibition by a given GSI does not explain the previously observed differences in functional and pharmacological properties among various GSIs.
Physiological Differences Between Heat Tolerant and Heat Intolerant Young Healthy Women

ABSTRACT Purpose: Heat intolerance (HI) is determined in the Israel Defense Force according to a heat tolerance test (HTT) before returning to duty after an exertional heat stroke (EHS) event. Recently, increased numbers of female combatants resulted in an increased number of EHS cases among women and a higher percentage of heat intolerance (HI) individuals. We aimed to evaluate the differences between tolerance to heat among women performing an HTT in relation to their menstrual cycle phase. Method: Thirty-three female participants were sorted into two groups: HI and heat tolerant (HT) according to two HTTs performed during both the luteal and follicular phases of the menstrual cycle or while consuming and during a break from consuming contraceptives. Results: HT women had an 18% higher maximal oxygen uptake (p < .005, 95% CI [2.6,9.8]) and 1.2% lower skin temperature in the HTT at the during and follicular phases (p < .01, 95% CI [0.12,0.77]) and 1.7% lower at the off and luteal phases (p < .001, 95% CI [0.34,0.92]). The mean sweat rate was 14% lower among the HI group only at the HTT at the during and follicular phases (p < .05, 95% CI (3,88)]). Conclusion: We found that HT can be predicted using aerobic capacity and core body temperature. Moreover, during the luteal phase, women presented altered thermoregulation that decreased the probability of being HT. This emphasizes the importance of considering the HT/HI criteria in the HTT for women, according to their aerobic ability and menstrual-cycle phase.
The KCNE2 potassium channel β subunit is required for normal lung function and resilience to ischemia and reperfusion injury

The KCNE2 single transmembrane–spanning voltage‐gated potassium (Kv) channel β subunit is ubiquitously expressed and essential for normal function of a variety of cell types, often via regulation of the KCNQ1 Kv channel. A polymorphism upstream of KCNE2 is associated with reduced lung function in human populations, but the pulmonary consequences of KCNE2 gene disruption are unknown. Here, germline deletion of mouse Kcne2 reduced pulmonary expression of potassium channel α subunits Kcnq1 and Kcnb1 but did not alter expression of other Kcne genes. Kcne2 colocalized and coimmunoprecipitated with Kcnq1 in mouse lungs, suggesting the formation of pulmonary Kcnq1‐Kcne2 potassium channel complexes. Kcne2 deletion reduced blood O2, increased CO2, increased pulmonary apoptosis, and increased inflammatory mediators TNF‐α, IL‐6, and leukocytes in bronchoalveolar lavage (BAL) fluids. Consistent with increased pulmonary vascular leakage, Kcne2 deletion increased plasma, BAL albumin, and the BAL:plasma albumin concentration ratio. Kcne2−/− mouse lungs exhibited baseline induction of the reperfusion injury salvage kinase pathway but were less able to respond via this pathway to imposed pulmonary ischemia/reperfusion injury (IRI). We conclude that KCNE2 regulates KCNQ1 in the lungs and is required for normal lung function and resistance to pulmonary IRI. Our data support a causal relationship between KCNE2 gene disruption and lung dysfunction. —Zhou, L. , Köhncke, C. , Hu, Z. , Roepke, T. K. , Abbott, G. W.

The effects of multiple mice on children's talk and interaction

A classroom-based evaluation study examined the process of children's collaboration when using 1 or 2 mice at a desktop computer. The groupware was displayed on a PC with a single monitor, keyboard, and 1 or 2 mice. 26 school children (aged 6-7 yrs) worked in pairs to re-create a poem in pictorial format. In-depth qualitative examination of interaction using 'collaboration networks' highlighted differences in working styles between conditions. Children using 2 mice divided up their task, worked in parallel, and showed limited reciprocity and elaboration of ideas. Children sharing 1 mouse demonstrated varied behaviors ranging from highly collaboratively work to extreme domination by 1 partner. The implications of these results for the organization of tasks are discussed.
Childhood Socioeconomic Disadvantage and Risk of Fatty Liver in Adulthood: The Cardiovascular Risk in Young Finns Study

Fatty liver is a preventable cause of liver failure, but early risk factors for adulthood fatty liver are poorly understood. We examined the association of childhood socioeconomic disadvantage with adulthood fatty liver and tested adulthood risk factors of fatty liver as possible mediators of this link. The study population comprised 2,042 participants aged 3‐18 years at baseline (1980) from the longitudinal Cardiovascular Risk in Young Finns Study. Follow‐up with repeated clinical examinations was 31 years. Childhood socioeconomic disadvantage was assessed using data from parents’ socioeconomic position and socioeconomic circumstances in participants’ residential neighborhoods, categorized as high versus low socioeconomic disadvantage. Fatty liver was determined by ultrasound during the last follow‐up (2011) at ages 34‐49 years. Childhood and adulthood risk factors, including metabolic biomarkers and lifestyle variables, were assessed in clinical examinations. A total of 18.9% of the participants had fatty liver in adulthood. High childhood socioeconomic disadvantage was associated with an increased risk of fatty liver (risk ratio [95% confidence interval], 1.42 [1.18‐1.70]; P = 0.0002). This association was robust to adjustment for age, sex, and childhood risk factors of fatty liver, including high body mass index, elevated insulin, and low birth weight (1.33 [1.09‐1.62]; P = 0.005). High childhood socioeconomic disadvantage was also associated with the development of risk factors of fatty liver in adulthood. Adulthood risk factors linking childhood socioeconomic disadvantage with fatty liver included waist circumference (proportion mediated of the total effect of childhood socioeconomic disadvantage, 45%), body mass index (40%), systolic blood pressure (29%), insulin (20%), physical activity (15%), triglycerides (14%), and red meat consumption (7%). Conclusion: Childhood socioeconomic disadvantage was associated with multiple risk factors of fatty liver and increased likelihood of fatty liver in adulthood.
Ferromagnetism in ZnO- and GaN-Based Diluted Magnetic Semiconductors: Achievements and Challenges

Both GaN- and ZnO-based diluted semiconductors (DMSs) have recently attracted considerable interest fueled by theoretical predictions of ferromagnetic ordering in these materials above room temperature, making them especially attractive for spintronics. The intense experimental research that followed has revealed, however, a great deal of controversy. The local structure and magnetic behavior of GaN- and ZnO-based DMSs were found to depend strongly on a preparation technique and growth conditions for the materials of the same nominal composition and the reported results varied considerably from group to group. This problem highlighted clearly the lack of theoretical understanding of physical mechanisms underlying ferromagnetisms in these materials and the inadequacy of standard characterization techniques used to probe structural and magnetic properties of the DMSs. In this paper, we report on the recent progress in the theoretical and experimental studies of ZnO- and GaN-based DMSs and make special impact on critical discussion of experimental methods employed for investigation of their magnetic and optical properties.
The mismeasure of hands?

Some researchers argue that the ratio between the length of the second and fourth fingers, the 2D:4D ratio, reflects the levels of testosterone and other hormones people were exposed to in the womb. Measuring the ratio, these scientists say, can thus provide insight into the role of hormones in shaping adult attributes such as aggressiveness and sexual orientation. It may also reveal sports prowess and disease risk. But other researchers criticize this work. Ratios are statistically dubious, they contend, and the evidence linking the 2D:4D ratio to prenatal hormone levels is weak. Moreover, they say, the field of 2D:4D research is rife with unrepeatable results.
Etiologies, trends, and predictors of readmission in ST‐elevation myocardial infarction patients undergoing multivessel percutaneous coronary intervention

Recent trials have shown benefits with percutaneous coronary intervention (PCI) on nonculprit coronary vessels in select ST‐elevation myocardial infarction (STEMI) patients with multivessel coronary artery disease (CAD). However, readmission rates and causes in this high‐risk group are unknown. Objective of this study is to explore pattern, causes and factors associated with 30‐day readmission after multivessel PCI in STEMI patients.
Rationale and design of OPtimising thERapy to prevent Avoidable hospital admissions in Multimorbid older people (OPERAM): a cluster randomised controlled trial

Introduction Multimorbidity and polypharmacy are important risk factors for drug-related hospital admissions (DRAs). DRAs are often linked to prescribing problems (overprescribing and underprescribing), as well as non-adherence with drug regimens for different reasons. In this trial, we aim to assess whether a structured medication review compared with standard care can reduce DRAs in multimorbid older patients with polypharmacy. Methods and analysis OPtimising thERapy to prevent Avoidable hospital admissions in Multimorbid older people is a European multicentre, cluster randomised, controlled trial. Hospitalised patients ≥70 years with ≥3 chronic medical conditions and concurrent use of ≥5 chronic medications are included in the four participating study centres of Bern (Switzerland), Utrecht (The Netherlands), Brussels (Belgium) and Cork (Ireland). Patients treated by the same prescribing physician constitute a cluster, and clusters are randomised 1:1 to either standard care or Systematic Tool to Reduce Inappropriate Prescribing (STRIP) intervention with the help of a clinical decision support system, the STRIP Assistant. STRIP is a structured method performing customised medication reviews, based on Screening Tool of Older People’s Prescriptions/Screening Tool to Alert to Right Treatment criteria to detect potentially inappropriate prescribing. The primary endpoint is any DRA where the main reason or a contributory reason for the patient’s admission is caused by overtreatment or undertreatment, and/or inappropriate treatment. Secondary endpoints include number of any hospitalisations, all-cause mortality, number of falls, quality of life, degree of polypharmacy, activities of daily living, patient’s drug compliance, the number of significant drug–drug interactions, drug overuse and underuse and potentially inappropriate medication. Ethics and dissemination The local Ethics Committees in Switzerland, Ireland, The Netherlands and Belgium approved this trial protocol. We will publish the results of this trial in a peer-reviewed journal. Main funding European Union’s Horizon 2020 programme. Trial registration number NCT02986425 , SNCTP000002183 , NTR6012, U1111-1181-9400.
Reporting quality of systematic reviews of interventions aimed at improving vaccination coverage: compliance with PRISMA guidelines

ABSTRACT Systematic reviews have become increasingly important for informing clinical practice and policy; however, little is known about the reporting characteristics and quality of SRs of interventions to improve immunization coverage in different settings. The aim of this study was to assess the reporting quality of systematic reviews of interventions aimed at improving vaccination coverage using the recommended Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guideline. PubMed and Cochrane Library were searched to identify SRs of interventions to improve immunization coverage, indexed up to May 2016. Two authors independently screened the search output, assessed study eligibility, and extracted data from eligible SRs using a 27-item data collection form derived from PRISMA. Discrepancies in reviews assessments were resolved by discussion and consensus. A total of 57 reviews were included in this study with a mean percentage of applicable PRISMA items that were met across all studies of 66% (range 19–100%) and median compliance of 70%. 39 out of the 57 reviews were published after the release of the PRISMA statement in 2009. Highest compliance was observed in items related to the “description of rational”, “description of eligibility criteria”, “synthesis of results” and “provision of a general interpretation of the results” (items #3, #6, #14 and #26, respectively). Compliance was poorest in the items “describing summary of evidence” (item 24, 19%), “describing indication of review protocol and registration” (item 5, 26%) and “describing results of risk of bias across studies (item 22, 33%). The overall reporting quality of systematic reviews of interventions to improve vaccination coverage requires significant improvement. There remains a need for additional research targeted at addressing potential barriers to compliance and strategies to improve compliance with PRISMA guideline.
Long non-coding RNA LINC01287 promotes breast cancer cells proliferation and metastasis by activating Wnt/ß-catenin signaling.

OBJECTIVE Long noncoding RNA (lncRNAs) frequently exhibited abnormal levels in numerous tumors and other diseases in current biological researches. LINC01287, a newly discovered lncRNA, has been found to act as an oncogene in hepatocellular carcinoma. The aim of this research was to explore the expressions and functions of LINC01287 in breast cancer (BC). PATIENTS AND METHODS The relative expressions of LINC01287 in BC tissues and cells were determined using RT-PCR. The associations between the LINC01287 expression, the clinicopathological factors, and the overall survival of BC patients were statistically examined. The apoptosis and proliferation abilities of MCF-7 and MDA-MB-468 cells were analyzed by MTT and flow cytometry assay after LINC01287 knockdown. The effects of LINC01287 in migration and invasion were determined using wound-healing and transwell assays. The protein expressions of the Wnt/β-catenin pathway were determined using Western blot. RESULTS We showed that the levels of LINC01287 were significantly upregulated in BC tissues and BC cell lines, and the abnormal expressions of LINC01287 were correlated with TNM stage and lymph node metastasis. A distinct difference was observed and indicated that BC patients with higher LINC01287 expressions had significantly shorter overall survival than patients with lower LINC01287 expressions. The multivariate analysis demonstrated that LINC01287 expression was independently correlated with the overall survival. Si-LINC01287 transfection significantly inhibited the proliferation and metastasis of BC cells, and further promoted apoptosis. Besides, the knockdown of LINC01287 suppressed Wnt/β-catenin activation and affected the expressions of β-catenin, cyclin D1, and c-myc. CONCLUSIONS Our findings indicated that the new lncRNA LINC01287 was correlated with poor clinical outcome and may function as a novel prognostic biomarker and therapeutic target in the development of antineoplastic therapies for BC.
Linking brain activation to topological organization in the frontal lobe as a synergistic indicator to characterize the difference between various cognitive processes of executive functions

Abstract. Executive functions (EFs) associated with the frontal lobe are vital for goal-orientated behavior. To date, limited efforts have been made to examine the relationships among the behavior, brain activation, and topological organization of functional networks in the frontal lobe underlying various EF tasks, including inhibition, working memory, and cognitive flexibility. In this study, functional near-infrared spectroscopy neuroimaging technique was used to systematically inspect the differences in the brain activation and the topological organization of brain networks between various EF tasks in the frontal lobe. In addition, the relationships between brain activation/network properties and task performances and the relationships between brain activation and network properties were, respectively, examined for different EF tasks. Consequently, we have discovered that the nodal and global properties of the resting-state and task-evoked networks, respectively, exhibited significant correlations with the activation of various brain regions during various EF tasks. In particular, the measure that links the neural activation to the topological organization of the brain networks in the frontal lobe can serve as a synergistic indicator to examine the difference between various EF tasks, which paves a way toward a comprehensive understanding of the neural mechanism underlying EFs.
On the Nakagaini-m crosscorrelation function

The generic-order crosscorrelation function between two non-identically distributed Nakagami-m fading processes is derived assuming a space-frequency diversity scenario with horizontally spaced omnidirectional antennas at the mobile station. Our result allows for distinct fading parameters, power imbalance, antenna, spacing/angle, and frequency separation. Based on it, the coherence bandwidth and the coherence time/distance of the Nakagami-m channel are also obtained. The latter is found to be practically identical to the coherence time/distance of the Rayleigh channel.
Influence of the fixed implant-supported provisional phase on the esthetic final outcome of implant-supported crowns: 3-year results of a randomized controlled clinical trial.

OBJECTIVES The aim of this investigation was to evaluate whether the use of a provisional implant-supported crown improves the final esthetic outcome of implant crowns that are placed within esthetic sites. MATERIALS AND METHODS Twenty endosseous implants were inserted in sites 13 to 23 (FDI) in 20 patients. Following the reopening procedure, a randomization process assigned them to either cohort group 1: a provisional phase with soft tissue conditioning using the "dynamic compression technique" or cohort group 2: without a provisional phase. Screw-retained all ceramic crowns were inserted. Clinical follow-up appointments were completed at 36 months evaluating clinical, radiographic outcomes, and implant success and survival. RESULTS After 3 years, all implants survived; one implant-supported crown was excluded from the study due to adjacent tooth failure replaced with a further implant supported crown. Modified pink esthetic score (ModPES) scores were significantly different between groups 1 and 2 (P = .018); white esthetic scores (WES) were not statistically different between both groups (P = .194). Mean values of combined modPES and WES were 15.6 for group 1, with a SD of 3.20. Group 2 had a mean combined modPES and WES of 12.2, with a SD of 3.86. Mean bone loss after 3 year was -0.05 and -0.04 mm for groups 1 and 2 respectively, without being statistically significant. CONCLUSION Fixed implant-supported provisionals improve the final esthetic outcome of the peri-implant mucosa.
