Lean mass and biological maturation as predictors of muscle power and strength performance in young athletes

Background The biological maturation (BM) analyzed by peak height velocity (PHV) and bone age (BA), and lean body mass has been associated with the strength and muscle power of young athletes. However, the ability of BM (PHV and BA) and LM markers to predict muscle strength and power in young athletes remains uncertain. Objective The Aim was determine the predicting power of BM markers (PHV and BA) and LM in relation to muscle power of upper and lower limbs and muscle strength of upper limbs in adolescent athletes at puberty. Methods Ninety-two adolescent athletes (both sexes; age 12.4 ± 1.02 years) were assessed for body composition by dual-energy X-ray absorptiometry (DXA). Power of upper limbs (ULP), force handgrip (HG), vertical jump (VJ) and countermovement jump (CMJ) were recorded. BM was predicted by mathematical models to estimate PHV and BA. Multilayer artificial neural network analyses (MLP’s) were used to determine the power of prediction of LM, PHV and BA on muscle power and strength of upper- and lower-limbs of the athletes. Results LM, BA and PHV were associated with HG (r>0.74, p<0.05) and ULS (r>0.60, p<0.05) in both sexes. In both sexes BA was associated with VJ (r>0.55, p<0.05) and CMJ (r>0.53, p<0.05). LM indicated associations (r>0.60, p<0.05) with BA and with PHV (r<0.83, p<0.05) in both sexes. MLP’s analysis revealed that the LM provides > 72% of probability to predict the muscle power of upper- and lower-limbs, and the strength of the upper limbs; whereas PHV provides > 43% and bone age >64% in both female and male adolescent athletes. Conclusion We identified that, like PHV and BA, LM is a strong predictor of low cost of both upper limbs muscle strength and upper and lower limbs power in adolescent athletes.
Comparing predictors of sentence self-paced reading times: Syntactic complexity versus transitional probability metrics

When estimating the influence of sentence complexity on reading, researchers typically opt for one of two main approaches: Measuring syntactic complexity (SC) or transitional probability (TP). Comparisons of the predictive power of both approaches have yielded mixed results. To address this inconsistency, we conducted a self-paced reading experiment. Participants read sentences of varying syntactic complexity. From two alternatives, we selected the set of SC and TP measures, respectively, that provided the best fit to the self-paced reading data. We then compared the contributions of the SC and TP measures to self-paced reading times when entered into the same model. Our results showed that while both measures explained significant portions of variance in reading times (over and above control variables: word/sentence length, word frequency and word position) when included in independent models, their contributions changed drastically when SC and TP were entered into the same model. Specifically, we only observed significant effects of TP. We conclude that in our experiment the control variables explained the bulk of variance. When comparing the small effects of SC and TP, the effects of TP appear to be more robust.
‘No test, no disease’: Multilevel barriers to HIV testing among young men who have sex with men and transgender women in three semi-urban areas in Thailand

Abstract Young gay and other men who have sex with men and young transgender women in Thailand continue to be at high risk for HIV infection. We explored multilevel influences on HIV testing in order to inform the design of tailored interventions. We conducted four focus group discussions with 16–20-year-old gay men and transgender persons (n = 25) and 17 key informant interviews with healthcare providers, NGO leaders, and youth advocates. Focus groups and interviews were transcribed and reviewed using thematic analysis in Thai and English language by a bilingual team. We identified intersecting, culturally situated barriers at individual (lack of HIV knowledge, low HIV risk perception, denial), social (intersectional sexual- and HIV-related stigma, lack of family communication), institutional (inadequate and non-LGBT-inclusive sexual health education in schools, lack of youth-friendly clinics) and policy levels (parental consent requirements for HIV testing by minors). Multilevel and multisystem factors coalesce to form extensive barriers to HIV testing access and utilisation and promote disengagement from HIV prevention more broadly. Multicomponent, youth-engaged interventions informed by Thai sociocultural history and practices are needed in renewed approaches to HIV prevention and testing to end the epidemic among young gay and transgender people in Thailand.
Association Between Psychological Readiness and Knee Laxity and Their Predictive Value for Return to Sport in Patients With Anterior Cruciate Ligament Reconstruction

Background: Deciding when patients are ready to return to sport (RTS) after an anterior cruciate ligament (ACL) reconstruction (ACLR) is challenging. The understanding of which factors affect readiness and how they may be related is limited. Therefore, despite widespread use of RTS testing, there is a lack of knowledge about which tests are informative on the ability to resume sports. Purpose: To examine whether there is an association between knee laxity and psychological readiness to RTS after ACLR and to evaluate the predictive value of these measures on sports resumption. Study Design: Cohort study; Level of evidence, 2. Methods: Patients aged ≥16 years engaged in physical activity/sports before injury were recruited at routine clinical assessment 9-12 months after ACLR. Exclusion criteria were concomitant ligament surgery at ACLR and/or previous ACL injury in the contralateral knee. At baseline, a project-specific activity questionnaire and the ACL–Return to Sport After Injury (ACL-RSI) scale were completed. Knee laxity was assessed by use of the Lachman test, KT-1000 arthrometer, and pivot-shift test. Two years after surgery, knee reinjuries and RTS status (the project-specific questionnaire) were registered. Associations between psychological readiness and knee laxity were evaluated with the Spearman rho test, and predictive ability of the ACL-RSI and knee laxity tests were examined using regression analyses. Results: Of 171 patients screened for eligibility, 132 were included in the study. There were small but significant associations between the ACL-RSI score and the Lachman test (rho = −0.18; P = .046) and KT-1000 arthrometer measurement (rho = −0.18; P = .040) but no association between the ACL-RSI and the pivot-shift test at the time of recruitment. Of the total patients, 36% returned to preinjury sport level by 2 years after surgery. Higher age, better psychological readiness, and less anterior tibial displacement (KT-1000 arthrometer measurement) were significant predictors of 2-year RTS (explained variance, 33%). Conclusion: Small but significant associations were found between measurements of psychological readiness and anterior tibial displacement, indicating that patients with less knee laxity after ACLR feel more ready to RTS. ACL-RSI and KT-1000 arthrometer measurements were independent predictors of 2-year RTS and should be considered in RTS assessments after ACLR.
Plant material selection, collection, preservation, and storage for nuclear DNA content estimation

In theory, any plant tissue providing intact nuclei in sufficient quantity is suitable for nuclear DNA content estimation using flow cytometry (FCM). While this certainly opens a wide variety of possible applications of FCM, especially when compared to classical karyological techniques restricted to tissues with active cell division, tissue selection and quality may directly affect the precision (and sometimes even reliability) of FCM measurements. It is usually convenient to first consider the goals of the study to either aim for the highest possible accuracy of estimates (e.g., for inferring genome size, detecting homoploid intraspecific genome size variation, aneuploidy, among others), or to decide that histograms of reasonable resolution provide sufficient information (e.g., ploidy level screening within a single model species). Here, a set of best practices guidelines for selecting the optimal plant tissue for FCM analysis, sampling of material, and material preservation and storage are provided. In addition, factors potentially compromising the quality of FCM estimates of nuclear DNA content and data interpretation are discussed.
The effect of momentary mood on appraisal of facial affect and distrust: an experimental approach using ambulatory assessment

ABSTRACT Previous laboratory studies have demonstrated that an observer’s current mood can influence their processing of facial stimuli, for instance, the appraisal of facial affect. The aim of the present study was to explore the association between current mood and face processing in participants’ daily lives, thereby making use of naturally occurring affective states. We employed Ambulatory Assessment (AA) and included two experimental tasks to test whether current mood predicts how participants evaluate (i) the valence of emotional faces and (ii) facial trustworthiness. We hypothesised a mood-congruent processing, such that individuals would rate pictures of faces more negatively and less trustworthy, the more negative their current mood was. We recruited 42 participants who completed a 7-day AA study with six random prompts per day. At each prompt, participants provided self-reports on momentary mood and completed an emotion rating task and a hypothetical distrust game. Results show that negative momentary mood was significantly associated with higher levels of distrust, but was not significantly associated with more negative emotion ratings. We discuss the incremental value and feasibility of implementing experimental tasks in AA contexts and the opportunities this opens for assessing affective and cognitive processes in natural environments.
Different routes of administration in chronic migraine prevention lead to different placebo responses: a meta-analysis.

ABSTRACT Placebo response is a powerful determinant of health outcomes in several disorders. Meta-analysis of clinical trials in pain conditions shows that it can contribute up to 75% of the overall treatment effect. Placebo response deriving from different routes of administration is poorly understood in primary headaches' pharmacological prevention. Thus, this meta-analysis aims to analyze how different routes of administration affect the placebo response in chronic migraine (CM). We conducted a meta-analysis with 7 randomized, double-blind, placebo-controlled clinical trials, with 5672 patients older than 18 years who suffer from CM without associated comorbidities. We compared those who received a placebo-administered agent for the preventive treatment of CM subcutaneous, endovenous, or oral against those who received multiple head injections. The primary outcome was reduction in the number of days with migraine in the month assessed at 12, 16, and 24 weeks of treatment compared with baseline. Our study shows that placebo responses were greater when botulinum toxin was applied to the head, followed by intravenous injection of the anti-calcitonin gene-related peptide monoclonal antibody eptinezumab. Oral topiramate and subcutaneous monoclonal showed no difference, being inferior to head injection. Administration route affects placebo responses in CM preventive treatment. Elucidating the underlying mechanisms that mediate a placebo response in migraine treatment is beneficial to clinical practice and drug development, especially when comparing drugs with different routes of administration, with the effect of application to the head being superior to the other routes in this study. In our study the placebo response accounted for approximately 75% of the therapeutic gain in the treatment of CM.
Preventive Anti-inflammatory Diet to Reduce Gastrointestinal Inflammation in Familial Adenomatous Polyposis Patients: A Prospective Pilot Study

Cancer is known to be related to inflammatory conditions. This study suggests that anti-inflammatory dietary intervention may potentially prevent adenomas and cancer in FAP patients by reducing systemic and tissue inflammatory indices. Familial adenomatous polyposis (FAP) is an autosomal-dominant hereditary condition associated with germline mutations in the adenomatous polyposis coli gene. Patient management involves prophylactic surgery and intensive life-long endoscopic surveillance. Diet is a major concern for patients with FAP, who are generally free of symptoms before surgery but tend to have issues related to bowel function postoperatively. We hypothesized that a low-inflammatory diet based on the principles and recipes of the Mediterranean diet would reduce markers of local and systemic inflammation. Twenty-eight patients with FAP over 18 years of age who underwent rectum-sparing prophylactic colectomy and were included in our surveillance program participated in a pilot dietary intervention study. Blood and stool samples at baseline (T0), at the end of the dietary intervention (T1, three months), and at the end of the study (T2, six months after T0) were collected. Gastrointestinal inflammation markers including fecal calprotectin, cyclooxygenase-2, and 15-hydroxyprostaglandin dehydrogenase were evaluated. Serum calprotectin, insulin, insulin-like growth factor-1, C-reactive protein, and glycated hemoglobin were also assessed. Significant changes in serum calprotectin, insulin, and insulin-like growth factor-1 levels occurred over time. Borderline significant changes were observed in the neutrophil–lymphocyte ratio. These changes were noticeable immediately at the end of the 3-month active dietary intervention (T1). A significant increase in 15-hydroxyprostaglandin dehydrogenase expression in the normal crypts of matched samples was also observed between T0 and T2. This pilot study supports the hypothesis that a low-inflammatory diet can modulate gastrointestinal markers of inflammation in individuals with FAP. Prevention Relevance: Cancer is known to be related to inflammatory conditions. This study suggests that anti-inflammatory dietary intervention may potentially prevent adenomas and cancer in FAP patients by reducing systemic and tissue inflammatory indices.
Nigerian Study Validates Wide Variations in Epilepsy Prevalence and Elucidates Potential Targets for Disease Prevention

For more than a decade, epilepsy has been established as one the most devastating of health states in terms of its impact on disability and premature mortality for those affected.1 Substantial efforts have been made to delineate the burden of epilepsy globally and to identify opportunities for epilepsy prevention, particularly opportunities relevant to resource-limited settings where the epilepsy treatment gap undoubtedly worsens disease burden.2 Wide differences in epilepsy prevalence have long been noted, with the highest burdens being in low-income, tropical settings, but whether these differences are due to true differences in disease distribution vs study methodology variation has remained unknown. In 2017, in a systematic review, Fiest et al.3 identified incidence data and information on age strata as key gaps in our understanding of the epidemiology of epilepsy globally.
Levels of cross-resistance to pyrethroids conferred by the Vssc knockdown resistance allele 410L+1016I+1534C in Aedes aegypti

Aedes aegypti is a primary vector of viral pathogens and is responsible for millions of human infections annually that represent critical public health and economic costs. Pyrethroids are one of the most commonly used classes of insecticides to control adult A. aegypti. The insecticidal activity of pyrethroids depends on their ability to bind and disrupt the voltage-sensitive sodium channel (VSSC). In mosquitoes, a common mechanism of resistance to pyrethroids is due to mutations in Vssc (hereafter referred as knockdown resistance, kdr). In this study, we found that a kdr (410L+V1016I+1534C) allele was the main mechanism of resistance in a pyrethroid-resistant strain of A. aegypti collected in Colombia. To characterize the level of resistance these mutations confer, we isolated a pyrethroid resistant strain (LMRKDR:RK, LKR) that was congenic to the susceptible Rockefeller (ROCK) strain. The full-length cDNA of Vssc was cloned from LKR and no additional resistance mutations were present. The levels of resistance to different pyrethroids varied from 3.9- to 56-fold. We compared the levels of resistance to pyrethroids, DCJW and DDT between LKR and what was previously reported in two other congenic strains that share the same pyrethroid-susceptible background (the ROCK strain), but carry different kdr alleles (F1534C or S989P + V1016G). The resistance conferred by kdr alleles can vary depending on the stereochemistry of the pyrethroid. The 410L+1016I+1534C kdr allele does not confer higher levels of resistance to six of ten pyrethroids, relative to the 1534C allele. The importance of these results to understand the evolution of insecticide resistance and mosquito control are discussed.
Impact of assumptions on future costs, disutility and mortality in cost-effectiveness analysis; a model exploration

Introduction In cost-effectiveness analyses, the future costs, disutility and mortality from alternative causes of morbidity are often not completely taken into account. We explored the impact of different assumed values for each of these factors on the cost-effectiveness of screening for colorectal cancer (CRC) and esophageal adenocarcinoma (EAC). Methods Twenty different CRC screening strategies and two EAC screening strategies were evaluated using microsimulation. Average health-related expenses, disutility and mortality by age for the U.S. general population were estimated using surveys and lifetables. First, we evaluated strategies under default assumptions, with average mortality, and no accounting for health-related costs and disutility. Then, we varied costs, disutility and mortality between 100% and 150% of the estimated population averages, with 125% as the best estimate. Primary outcome was the incremental cost per quality-adjusted life-year (QALY) gained among efficient strategies. Results The set of efficient strategies was robust to assumptions on future costs, disutility and mortality from other causes of morbidity. However, the incremental cost per QALY gained increased with higher assumed values. For example, for CRC, the ratio for the recommended strategy increased from $15,600 with default assumptions, to $32,600 with average assumption levels, $61,100 with 25% increased levels, and $111,100 with 50% increased levels. Similarly, for EAC, the incremental costs per QALY gained for the recommended EAC screening strategy increased from $106,300 with default assumptions to $198,300 with 50% increased assumptions. In sensitivity analyses without discounting or including only above-average expenses, the impact of assumptions was relatively smaller, but best estimates of the cost per QALY gained remained substantially higher than default estimates. Conclusions Assumptions on future costs, utility and mortality from other causes of morbidity substantially impact cost-effectiveness outcomes of cancer screening. More empiric evidence and consensus are needed to guide assumptions in future analyses.
Trajectories of Distress Regulation During Preschool Vaccinations: Child and Caregiver Predictors.

ABSTRACT Recent research has highlighted the need for a deeper understanding of the heterogeneity in trajectories of children's distress following acute pain exposure, moving beyond group means of behavioural pain scores at a single timepoint. During preschool vaccinations, three distinct trajectories of post-vaccination pain regulation have been elucidated, with approximately 75% of children displaying trajectories characterized by down-regulation to no distress by two minutes post-needle and 25% concerningly failing to down-regulate by two-minutes. The objective of the present study was to examine child and caregiver predictors of preschool children's post-vaccination regulatory patterns. Our results indicated that higher child baseline distress, more caregiver coping-promoting verbalizations in the first minute following the needle, less coping -promoting verbalizations in the second minute, and more caregiver distress-promoting verbalizations in the second minute following the needle were associated with membership in the trajectories characterized by high distress. Further, while all children's pain-related distress at various timepoints throughout the appointment was most strongly predicted by prior pain scores, different patterns of associations emerged depending on the trajectory exhibited. This research highlights both the need to minimize distress prior to the needle in order to avoid the highly distressed trajectory as well as the importance of considering the heterogeneity of trajectories of preschool pain responding when examining the factors that are associated with children's pain-related distress.
Foliar application of seed water extract of Nigella sativa improved maize growth in cadmium-contaminated soil

Cadmium (Cd) is a widespread heavy metal, which commonly exert negative impacts on agricultural soils and living organisms. Foliar application of seed water extract of black cumin (Nigella sativa L.) can mitigate the adverse impacts of Cd-toxicity in plants through its rich antioxidants. This study examined the role of seed water extracts of N. sativa (NSE) in mitigating the adverse impacts of Cd-toxicity on maize growth. Two maize genotypes (synthetic ‘Neelum’ and hybrid ‘P1543’) were grown under 0, 4, 8 and 12 mg Cd kg-1 soil. The NSE was applied at three different concentrations (i.e., 0, 10 and 20%) as foliar spray at 25 and 45 days after sowing. All Cd concentrations had no effect on germination percentage of both genotypes. Increasing Cd concentration linearly decreased root and allometric attributes, gas exchange traits and relative water contents of hybrid genotype. However, gas exchange traits of synthetic genotype remained unaffected by Cd-toxicity. Overall, hybrid genotype showed better tolerance to Cd-toxicity than synthetic genotype with better germination and allometric attributes and less Cd accumulation. Foliar application of NSE lowered negative effects of Cd-toxicity on all studied traits, except relative water contents. In conclusion, foliar application of NSE seemed a viable option to improve maize growth in Cd-contaminated soil.
Does time change the anxiety and depression scores for pregnant women on Covid‐19 pandemic?

Post‐traumatic stress disorder, the tip form of stress disorder, is considered as delayed onset if the symptoms occur at least 6 months after the main effect. The aim of our study was to evaluate the severity of anxiety and depression in pregnant women during the coronavirus disease (COVID‐19) pandemic, in addition to investigating the demographic and economic aspects affecting maternal anxiety and depression scores, 6 months after the onset of the COVID‐19 pandemic.
