We aimed to analyze the baseline features and clinical outcomes of patients younger than 80 years undergoing transfemoral transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) enrolled in the OBservational Study of Effectiveness of SAVR‐TAVR procedures for severe Aortic steNosis Treatment (OBSERVANT) real‐world study, focusing on variables guiding Heart Team decision toward TAVI.
Identity and functions of inorganic and inositol polyphosphates in plants

Summary Inorganic polyphosphates (polyPs) and inositol pyrophosphates (PP‐InsPs) form important stores of inorganic phosphate and can act as energy metabolites and signaling molecules. Here we review our current understanding of polyP and inositol phosphate (InsP) metabolism and physiology in plants. We outline methods for polyP and InsP detection, discuss the known plant enzymes involved in their synthesis and breakdown, and summarize the potential physiological and signaling functions for these enigmatic molecules in plants.
Repurposing an anti‐cancer agent for the treatment of hypertrophic heart disease

Coronary microvascular dysfunction combined with maladaptive cardiomyocyte morphology and energetics is a major contributor to heart failure advancement. Thus, dually enhancing cardiac angiogenesis and targeting cardiomyocyte function to slow, or reverse, the development of heart failure is a logical step towards improved therapy. We present evidence for the potential to repurpose a former anti‐cancer Arg‐Gly‐Asp (RGD)‐mimetic pentapeptide, cilengitide, here used at low doses. Cilengitide targets αvβ3 integrin and this protein is upregulated in human dilated and ischaemic cardiomyopathies. Treatment of mice after abdominal aortic constriction (AAC) surgery with low‐dose cilengitide (ldCil) enhances coronary angiogenesis and directly affects cardiomyocyte hypertrophy with an associated reduction in disease severity. At a molecular level, ldCil treatment has a direct effect on cardiac endothelial cell transcriptomic profiles, with a significant enhancement of pro‐angiogenic signalling pathways, corroborating the enhanced angiogenic phenotype after ldCil treatment. Moreover, ldCil treatment of Angiotensin II‐stimulated AngII‐stimulated cardiomyocytes significantly restores transcriptomic profiles similar to those found in normal human heart. The significance of this finding is enhanced by transcriptional similarities between AngII‐treated cardiomyocytes and failing human hearts. Taken together, our data provide evidence supporting a possible new strategy for improved heart failure treatment using low‐dose RGD‐mimetics with relevance to human disease. © 2019 The Authors.

Suppression of Charge Carrier Recombination in Lead-Free Tin Halide Perovskite via Lewis Base Post-Treatment.

Lead-free tin perovskite solar cells (PSCs) showed the most promise to replace the more toxic lead-based perovskite solar cells. However, the efficiency is significantly than that of lead-based PSCs as a result of low open-circuit voltage. This is due to the tendency of Sn2+ to oxidize into Sn4+ in the presence of air together with the formation of defects and traps caused by the fast crystallization of tin perovskite materials. Here, post-treatment of tin perovskite layer with edamine Lewis base to suppress the recombination reaction in tin halide PSCs resulting in efficiencies more than 10 %, which is the highest reported efficiency to date for pure tin-halide PSCs. The X-ray photoelectron spectroscopy data suggest that the recombination reaction is originated from the nonstoichiometric Sn:I ratio rather than Sn4+:Sn2+ ratio. Amine-group in edamine bonded the under-coordinated tin, passivating the dangling bonds and defects resulting in suppressed charge carrier recombination.
LL-37 Exacerbates Local Inflammation in Sepsis-Induced Acute Lung Injury by Preventing Mitochondrial DNA (mtDNA) Degradation-Induced Autophagy

Background Recent studies have proved that autophagy dysfunction in proinflammatory cells is involved in tissue damage and an excessive inflammatory response in sepsis. In the present study, we identified that the human antimicrobial peptide LL-37 facilitates resistance to DNase II-induced mitochondrial DNA (mtDNA) degradation and subsequent autophagy. Material/Methods We found higher serum levels of LL-37 in patients with severe sepsis compared to that in patients with mild sepsis. Neutrophils isolated from mice with sepsis after treatment with Cramp-mtDNA produced an excess of proinflammatory cytokines, including IL-1β, IL-6, IL-8, MMP-8, and TNF-α. Cramp-mtDNA in the lung samples from model animals with sepsis was detected by immunohistochemical staining. Results Exogenous delivery of Cramp-mtDNA complex significantly exacerbated lung inflammation but the antibody against Cramp-mtDNA attenuated the excessive inflammatory response in LPS-induced acute lung injury. The expression of proinflammatory cytokines in lungs was upregulated and downregulated after treatment with the complex and antibody, respectively. LC-3 expression in 16HBE cells increased after LPS induction, irrespective of stimulation with LL-37. Conclusions These data show that LL-37 treatment worsens local inflammation in sepsis-induced acute lung injury by preventing mtDNA degradation-induced autophagy.
Effects of Self-Controlled Knowledge of Results on Learning a Taekwondo Serial Skill

Allowing learners to control feedback has been an effective strategy in motor skills learning. However, most studies of self-controlled (SC) feedback have used simple tasks that may be dissimilar to sports skills that generally demand more degrees of freedom and cognition. Thus, this study investigated the effects of SC knowledge of results (KR) on learning a complex Taekwondo skill. Twenty-four undergraduate volunteers of both sexes, aged 18-35 years, practiced a specific serial Taekwondo skill that was novel to them. We divided participants randomly into SC and yoked groups and compared their performance after they learned a specific displacement sequence, finishing with a lateral kick (bandal-tchagui) at a punching bag within a target time span. During acquisition, all participants performed 48 trials divided into six blocks and, on a retention test 24 hours later, they performed 10 more trials. We found that both groups reduced their errors from the first to the last block of the acquisition phase and that the SC group showed a better performance on the retention test, relative to the yoked control group. SC KR participants requested KR mainly after good trials, though they showed no statistically significant differences between trials with and without KR. Their inefficiency in estimating their own errors may have been due to task complexity, since many aspects of the task beyond its temporal requirement demanded the learners’ attention. Our results, using a novel Taekwondo serial skill, confirm and extend the benefits of SC KR from just simple motor learning in past studies to learning complex motor skills.
Inhibition of platelet activation using vitamins

Abstract Some vitamins have beneficial effects on cardiovascular diseases, normalizing platelet function and preventing their excess activation. Anti-platelet vitamins can act directly through inhibitory biochemical pathways in platelets or indirectly by preventing damage to the endothelium or low-density lipoprotein from oxidation. As a rule, each vitamin alone is a weak inhibitor of platelet aggregation. However, in combination, they may act synergistically or enhance the effects of endogenous anti-platelet compounds, such as prostacyclin or nitric oxide, and appear to have a sufficient anti-thrombotic effect. This review will focus on vitamins, which inhibit platelet activation and the mechanisms of their action. The relationship between the vitamins that inhibit platelet aggregation and vascular diseases is examined.
Transcriptomic Analysis of Cellular Pathways in Healing Flexor Tendons of Plasminogen Activator Inhibitor 1 (PAI‐1/Serpine1) Null Mice

Injuries to flexor tendons can be complicated by fibrotic adhesions, which severely impair the function of the hand. Plasminogen activator inhibitor 1 (PAI‐1/SERPINE1), a master suppressor of fibrinolysis and protease activity, is associated with adhesions. Here, we used next‐generation RNA sequencing (RNA‐Seq) to assess genome‐wide differences in messenger RNA expression due to PAI‐1 deficiency after zone II flexor tendon injury. We used the ingenuity pathway analysis to characterize molecular pathways and biological drivers associated with differentially expressed genes (DEG). Analysis of hundreds of overlapping and DEG in PAI‐1 knockout (KO) and wild‐type mice (C57Bl/6J) during tendon healing revealed common and distinct biological processes. Pathway analysis identified cell proliferation, survival, and senescence, as well as chronic inflammation as potential drivers of fibrotic healing and adhesions in injured tendons. Importantly, we identified the activation of PTEN signaling and the inhibition of FOXO1‐associated biological processes as unique transcriptional signatures of the healing tendon in the PAI‐1/Serpine1 KO mice. Further, transcriptomic differences due to the genetic deletion of PAI‐1 were mechanistically linked to PI3K/Akt/mTOR, PKC, and MAPK signaling cascades. These transcriptional observations provide novel insights into the biological roles of PAI‐1 in tendon healing and could identify therapeutic targets to achieve scar‐free regenerative healing of tendons. © 2019 Orthopaedic Research Society.

Long-term effects of executive function training among veterans with chronic TBI

ABSTRACT Objective: To investigate long-term effects of GOALS executive function training in Veterans with chronic TBI. In a recently completed study Veterans with chronic TBI showed improvement immediately post-GOALS but not control training on measures of executive function, functional task performance, and emotion regulation. We now examine the long-term maintenance of post-GOALS training changes in the same sample. Setting: San Francisco VA Health Care System (SFVAHCS), and VA Northern California Health-Care System (VANCHS) in Martinez. Participants and Design: 24 Veterans with chronic TBI were assessed at baseline, post-GOALS training, and long-term follow-up 6+ months following completion of training with a structured telephone interview, neuropsychological and complex functional performance measures, and self-report measures of daily and emotional functioning. Results: Participants reported an increased likelihood of involvement in competitive employment/volunteering at follow-up (61%) compared to baseline (26%; χ2 = 5.66, p < .01, ѱ = .35). Repeated measures MANOVAS indicated improvement on attention/executive function (F = 13.85, p < .01, partial η2 = .42), complex functional task performance (GPS Total: F = 9.12, p < .01, partial η2 = .38) and daily functioning (MPAI Total: F = 3.23, p < .05, partial η2 = .21), and reduction in overall mood disturbance (POMS Total: F = 3.42, p < .05, partial η2 = .22) at follow-up relative to baseline. Discussion: Training in attention regulation applied to participant-defined goals is associated with meaningful long-term improvement in cognitive skills, emotion regulation, and daily functioning in Veterans with chronic TBI.
Characterizing behavioral health-related emergency department utilization among children with Medicaid: Comparing high and low frequency utilizers

ABSTRACT While the frequency of children’s behavioral health (BH)-related visits to the emergency department (ED) is rising nationwide, few studies have examined predictors of high rates of ED use. This study examines Florida Medicaid claims (2011–2012) for children age 0–18 who were seen in an emergency department (ED) for behavioral health (BH) conditions. A logistic regression model was used to explore factors associated with frequent ED use and patterns of psychotropic medication utilization. The majority (95%) of patients with at least one BH-related ED visit had three or fewer of these visits, but 5% had four or more. Seventy-four percent of ED visits were not associated with psychotropic medication, including over half (54%) of visits for attention deficit hyperactivity disorder (ADHD). Frequent ED use was higher among older children and those with substance use disorders. The implementation of interventions that reduce non-emergent ED visits through the provision of care coordination, social work services, and/or the use of community health workers as care navigators may address these findings.
Effectiveness of using assistive technology for time orientation and memory, in older adults with or without dementia

Abstract Aims The purposes of this study were to reveal the effectiveness of an electric calendar, showing the date and schedule automatically for older people, and to prove the characteristics of appropriate users. Material and Methods The participants were 27 older adults with or without dementia (9 men and 18 women, mean age: 81.5 ± 6.9 years, range: 72–94 years). The study design was a cross-over randomized controlled trial, with 15 participants (55.6%) allocated to the first group to use the electric calendar, and 12 participants (44.4%) to the second intervention group. The outcome measures are daily behaviors and cognitive function assessed by the Mini-Mental State Examination and Neurobehavioral Cognitive Status Examination. Results Participants showed significant increase in total Mini-Mental State Examination score (p = 0.020, a paired t-test) after intervention period, whereas there was no significant difference after no intervention. Daily activities related healthcare were improved. The participants with positive outcomes showed higher motivations, and around 18 points in Mini-Mental State Examination. Most healthy older adults mentioned that electric calendars were useful, but unnecessary. Conclusion and Significance Using the electric calendar was effective in improving global cognitive function and daily activities. The target users are older people, who (1) might have mild dementia, (2) have difficulties in daily activities, (3) can be supported by caregivers, and (4) have positive motivation to new technologies. IMPLICATIONS FOR REHABILITATION An electric calendar is effective on grovel cognitive function, and activities of daily living related to healthcare in older adults, as well as reality orientation therapy. The electric calendar can be useful for older people with mild dementia or mild cognitive impairment, having difficulties activities of daily living, supported by caregivers at regular intervals.
Air pollution and incident bladder cancer: A risk assessment

Dear editor, I have read with interest the article entitled “Ambient air pollution and incident bladder cancer risk: Updated analysis of the Spanish Bladder Cancer Study” by Turner et al. that evaluated the association between ambient particulate matter within a diameter of 2.5 (PM2.5), nitrogen dioxide (NO2) and bladder cancer incidence. Although there were no significant associations of ambient PM2.5 and NO2 concentrations with incident bladder cancer, some cautions should be paid to the methodology of their research. First, the authors adopted single pollutant and two pollutant models by using estimation data from residential areas and a dependent variable was personal information on incident bladder cancer. As there is a variation of ambient PM2.5 and NO2 within the same study area, individual exposure levels of ambient PM2.5 and NO2 should be used instead of estimated values, although there are difficulties of measuring individual data. Second, the authors adopted unconditional logistic regression models for the analysis. I suppose that case–control matching data were canceled and conservative results would be derived by their statistical procedure. Although there are some stronger factors than air pollutions for incident bladder cancer, conditional logistic regression models can be applied to case–control matching data. Finally, the authors cited a meta-analysis of cohort studies, presenting no significant association between air pollution and incident bladder cancer. The air pollution data were gathered by the same method, and I speculate that personal lifestyle factors would greatly contribute to the risk of bladder cancer. Yours sincerely Tomoyuki Kawada
The impact of caregiving on caregivers of older persons and its associated factors: a cross-sectional study.

INTRODUCTION Many older people rely on caregivers for support. Caring for older people can pose significant burdens for caregivers yet may also have positive effects. This study aimed to assess the impact on the caregivers and to determine factors associated with caregivers who were burdened. METHODS This was a cross-sectional study of 385 caregivers of older people who attended a community clinic in Malaysia. Convenience sampling was employed during the study period on caregivers who were aged ≥ 21 years and provided ≥ 4 hours of unpaid support per week. Participants were asked to complete a self-administered questionnaire, which included the Carers of Older People in Europe (COPE) index and the EASYCare Standard 2010 independence score. The COPE index was used to assess the impact of caregiving. A highly burdened caregiver was defined as one whose scores for all three COPE subscales were positive for burden. Care recipients' independence was assessed using the independence score of the EASYCare Standard 2010 questionnaire. Multiple logistic regression was used to determine the factors associated with caregiver burden. RESULTS 73 (19.0%) caregivers were burdened, of whom two were highly burdened. Caregivers' median scores on the positive value, negative impact and quality of support scales were 13.0, 9.0 and 12.0, respectively. Care recipients' median independence score was 18.0. Ethnicity and education levels were found to be associated with caregiver burden. CONCLUSION Most caregivers gained satisfaction and felt supported in caregiving. Ethnicity and education level were associated with a caregiver being burdened.
Neurocognitive status and return to work after moderate to severe traumatic brain injury.

PURPOSE/OBJECTIVE To examine the relationship of cognitive status to employment outcomes at 1-year post moderate-severe traumatic brain injury (TBI), using a brief telephone-administered instrument. Research Method/Design: Prospective longitudinal study in which 320 people with moderate-severe TBI, all employed at injury, were enrolled during inpatient rehabilitation and evaluated at 1-year postinjury. Follow-up measures included whether and when participants had returned to work (RTW), and cognitive status assessed with the Brief Test of Adult Cognition by Telephone (BTACT). Multivariable logistic regression and survival analyses were used to assess the contribution of BTACT (overall and subscale scores) to employment outcomes, controlling for covariates with known associations to those outcomes, including demographic variables, injury severity, and driving status. RESULTS Fewer than 40% of participants (n = 124) were employed at 1-year follow-up. BTACT scores were strongly associated with RTW even after controlling for known covariates. Females had faster and higher rates of RTW compared to males. Resumption of driving and injury severity were also related to RTW. CONCLUSIONS/IMPLICATIONS Neurocognitive status is a potentially modifiable factor with an important relationship to RTW following TBI. Vocational rehabilitation efforts should provide cognitive remediation or compensation as well as addressing transportation barriers. As a brief telephone-based assessment, the BTACT offers a new and efficient tool for evaluation of episodic memory and executive function.

A new inducible CRISPR‐Cas9 system useful for genome editing and study of double‐strand break repair in Candida glabrata

In recent years, the CRISPR‐Cas9 system has proven extremely useful for genome editing in many species, including the model yeast Saccharomyces cerevisiae and other yeast species such as Candida glabrata. Inducible CRISPR‐Cas9 systems have the additional advantage of allowing to separate the transformation step of the organism by the CRISPR‐Cas9 system, from the cutting and repair steps. This has indeed been developed in S. cerevisiae, where most inducible expression systems rely on the GAL promoters. Unfortunately, C. glabrata is gal− and lacks the GAL genes, like many other yeast species. We report here the use of a vector expressing cas9 under the control of the MET3 promoter, with the guide RNA cloned into the same plasmid. We show that it can be used efficiently in C. glabrata, for both described outcomes of CRISPR‐Cas9‐induced chromosome breaks; nonhomologous end joining in the absence of a homologous repair template; and homologous recombination in the presence of such a template. This system therefore allows easy editing of the genome of C. glabrata, and its inducibility may allow identification of essential genes in this asexual yeast, where spore lethality cannot be observed, as well as the study of double‐strand break repair.
Left atrial dimension and cardiovascular outcomes in patients with and without atrial fibrillation: a systematic review and meta-analysis

Objective The prognostic value of left atrial (LA) dimensions may differ between patients with and without atrial fibrillation (AF). Methods MEDLINE and EMBASE were searched for studies that investigated the association between LA echocardiographic parameters measured by transthoracic echocardiography and cardiovascular outcomes in patients with or without AF. Data were independently abstracted by two reviewers and pooled using random-effects meta-analysis. The primary outcome was incident stroke or thromboembolic events. Secondary outcomes were heart failure, all-cause mortality and major adverse cardiac events (MACE). Results Twenty-three studies of patients with AF (14 939 patients) and 68 studies of patients without AF (50 720 patients) in this systematic review. Increasing LA diameter was significantly associated with stroke and thromboembolic events in patients without AF (risk ratio (RR) 1.38, 95% CI 1.02 to 1.87; p=0.03), but not in patients with AF (RR 1.02, 95% CI 0.98 to 1.07; p=0.27; p for difference=0.05). Increasing LA diameter index was significantly associated with MACE in patients with AF (RR 1.13, 95% CI 1.09 to 1.17; p<0.001) and in patients without AF (RR 2.98, 95% CI 1.90 to 4.66; p<0.001), with stronger effects in non-AF populations (p for difference <0.001). Greater LA volume index was significantly associated with the risk of MACE in patients with AF (RR 1.01, 95% CI 1.00 to 1.02; p=0.03) and in non-AF populations (RR 1.08, 95% CI 1.05 to 1.10; p<0.001), the association being stronger in individuals without AF (p for difference <0.001). Conclusions Larger LA parameters were associated with various adverse cardiovascular events. Many of these associations were stronger in individuals without AF, highlighting the potential importance of LA myopathy.
