In this paper, a 3-D thermomechanical model of through-silicon vias (TSVs) has been analyzed and verified with in situ microscale strain measurements by synchrotron X-ray microdiffraction. Thereafter, a comprehensive stress/strain analysis on copper pumping and back-end-of-line (BEOL) cracking issues has been carried out. In addition, a design-of-experiments-based approach has been used to understand the effect of various parameters on copper pumping and BEOL stress. The results show that the smaller TSV diameter and thinner silicon die help reduce the copper pumping and thus mitigate BEOL stress.

Several plant-associated microbes synthesize the auxinic plant growth regulator phenylacetic acid (PAA) in culture; however, the role of PAA in plant-pathogen interactions is not well understood. In this study, we investigated the role of PAA during interactions between the phytopathogenic bacterium Pseudomonas syringae strain PtoDC3000 (PtoDC3000) and the model plant host, Arabidopsis thaliana. Previous work demonstrated that indole-3-acetaldehyde dehydrogenase A (AldA) of PtoDC3000 converts indole-3-acetaldehyde (IAAld) to the auxin indole-3-acetic acid (IAA). Here, we further demonstrated the biochemical versatility of AldA by conducting substrate screening and steady-state kinetic analyses, and showed that AldA can use both IAAld and phenylacetaldehyde as substrates to produce IAA and PAA, respectively. Quantification of auxin in infected plant tissue showed that AldA-dependent synthesis of either IAA or PAA by PtoDC3000 does not contribute significantly to the increase in auxin levels in infected A. thaliana leaves. Using available arogenate dehydratase (adt) mutant lines of A. thaliana compromised for PAA synthesis, we observed that a reduction in PAA-Asp and PAA-Glu is correlated with elevated levels of IAA and increased susceptibility. These results provide evidence that PAA/IAA homeostasis in A. thaliana influences the outcome of plant-microbial interactions.

Yaba monkey tumor virus (YMTV) and Tanapox virus (TPV) are members of the Yatapoxvirus genus and can infect humans and other primates. Despite the threat posed by yatapoxviruses, the factors determining their host range are poorly understood. In this study, we analyzed the ability of YMTV and TPV orthologs of vaccinia virus K3 (called 012 in YMTV and TPV), which share 75% amino acid identity with one another, to inhibit PKR from 15 different primate species. We first used a luciferase-based reporter, and found that YMTV and TPV K3 orthologs inhibited PKR in a species-specific manner and showed distinct PKR inhibition profiles. TPV 012 inhibited PKR from 11 primates, including humans, substantially better than YMTV 012. In contrast, both K3 orthologs inhibited the other four primate PKRs comparably well. Using YMTV 012 and TPV 012 hybrids, we mapped the region responsible for the differential PKR inhibition to the C- terminus of the K3 orthologs. Next, we generated chimeric vaccinia virus strains to investigate whether TPV K3 and YMTV K3 orthologs could rescue the replication of a vaccinia virus strain that lacks PKR inhibitors K3L and E3L. Virus replication in primate-derived cells generally correlated with the patterns observed in the luciferase-based assay. Together, these observations demonstrate that yatapoxvirus K3 orthologs have distinct PKR inhibition profiles and inhibit PKR in a species-specific manner, which may contribute to the differential susceptibility of primate species to yatapoxvirus infections.

Abstract Background By 2034, the number of US individuals with diabetes is predicted to increase from 23.7 to 44.1 million, and annual diabetes-related spending is expected to grow from $113 to $336 billion. Up to 55% of US Hispanics born in the year 2000 are expected to develop diabetes during their lifetime. Poor healthcare access and cultural barriers prevent optimal care, adherence, and clinical benefit, placing Hispanics at disproportionate risk for costly diabetes complications. Mobile technology is increasingly prevalent in all populations and can circumvent such barriers. Our group developed Dulce Digital, an educational text messaging program that improved glycemic control relative to usual care. Dulce Digital-Me (DD-Me) has been tailored to a participant’s individual needs with a greater focus on health behavior change. Methods This is a three-arm, parallel group, randomized trial with equal allocation ratio enrolling Hispanic adults with low income and poorly managed type 2 diabetes (N = 414) from a San Diego County Federally Qualified Health Center. Participants are randomized to receive Dulce Digital, Dulce Digital-Me-Automated, or Dulce Digital-Me-Telephonic. The DD-Me groups include Dulce Digital components plus personalized goal-setting and feedback delivered via algorithm-driven automated text messaging (DD-Me-Automated) or by the care team health coach (DD-Me-Telephonic) over a 12-month follow-up period. The study will examine the comparative effectiveness of the three groups in improving diabetes clinical control [HbA1c, primary outcome; low-density lipoprotein cholesterol (LDL-C), and systolic blood pressure (SBP)] and patient-provider communication and patient adherence (i.e., medication, self-management tasks) over 12 months and will examine cost-effectiveness of the three interventions. Discussion Our comparative evaluation of three mHealth approaches will elucidate how technology can be integrated most effectively and efficiently within primary care-based chronic care model approaches to reduce diabetes disparities in Hispanics and will assess two modes of personalized messaging delivery (i.e., automated messaging vs. telephonic by health coach) to inform cost and acceptability.

Sulfate is an important nutrient that modulates a diverse range of molecular and cellular functions in mammalian physiology. Over the past 2 decades, animal studies have linked numerous sulfate maintenance genes with neurological phenotypes, including seizures, impaired neurodevelopment, and behavioral abnormalities. Despite sulfation pathways being highly conserved between humans and animals, less than one third of all known sulfate maintenance genes are clinically reportable. In this review, we curated the temporal and spatial expression of 91 sulfate maintenance genes in human fetal brain from 4 to 17 weeks post conception using the online Human Developmental Biology Resource Expression. In addition, we performed a systematic search of PubMed and Embase, identifying those sulfate maintenance genes linked to atypical neurological phenotypes in humans and animals. Those findings, together with a search of the Online Mendelian Inheritance in Man database, identified a total of 18 candidate neurological dysfunction genes that are not yet considered in clinical settings. Collectively, this article provides an overview of sulfate biology genes to inform future investigations of perturbed sulfate homeostasis associated with neurological conditions.

This fact sheet provides examples of native plant species that can be salvaged from sites slated for development for urban landscaping. It also provides strategies to increase the economic and logistic feasibility of salvaging efforts. The authors found 80 salvageable native plant species on a proposed development site, 31 of which had the potential to establish in soils more sterile and compacted than the soils in which these species typically flourish.

The purpose of this study was to compare the attitudes of anesthesiologists and nurse anesthetists toward collaboration with each other. Data for this descriptive, comparative study were gathered through a mailed survey to 501 nurse anesthetists and 353 anesthesiologists licensed to practice in 1 state of the United States. Attitude toward collaboration was measured using an adaptation of the Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration. The mean total scores were compared using the t test for independent groups. Mean total scores were higher for the nurse anesthetist group (n = 238) compared with the anesthesiologist group (n = 66). Analysis demonstrated that this difference was significant ( t = 14.6, P < .05). Additional analyses failed to show a significant difference based on sexual gender. The results of this study provide some evidence that the divergent perspectives regarding collaboration previously demonstrated between physicians and nurses may also exist in the specialty field of anesthesia. This study provided no support for the supposition that gender contributes to the differences in attitude toward collaboration between physicians and nurses. [ABSTRACT FROM AUTHOR]

Background: Response-contingent time-out has been shown to be an effective technique for enhancing fluency in people who stutter. However, the factors that determine individual responsiveness to time-out are not well understood. Aims: The study investigated the effectiveness of using response-contingent time-out to reduce stuttering frequency in adults who stutter. In addition, it investigated the predictive value of participants' stutter severity, age, previous treatment history, and type of stutter on the responsiveness to time-out conditioning. Methods & Procedures: Sixty people who stutter participated in the study. Half were exposed to time-out following each moment of stuttering over a 40-min period, the remaining participants acted as controls. Outcomes & Results: Results showed that individuals who stutter are highly responsive to time-out, and that the participants with a more severe stutter responded better than those with a mild stutter. To a lesser degree, previous treatment and speech rate also influenced treatment success. Age and type of stutter did not, although the proportion of repetition types of stutters increased over the experiment conditions, with prolongations and blocks decreasing, for the treatment group. Conclusions: This simple operant conditioning treatment method is effective in reducing stuttering. Individuals respond to time-out regardless of their age, type of stutter, stuttering severity or treatment history, thus it is a treatment methodology potentially suitable for all clients. This study investigated initial responsiveness to time-out; therefore, further research is necessary to determine the durability of fluency over time. [ABSTRACT FROM AUTHOR]

Introduction: Relationship talk refers to talking with a partner about the relationship, what one needs from one's partner, and/or the relationship implications of a shared stressor. This prospective study examined the effects of relationship talk on couples' psychosocial adaptation to lung cancer.Methods: A total of 169 patients (63% male) and 167 of their partners completed a series of questionnaires within 4-weeks of treatment initiation for newly diagnosed lung cancer (baseline). Follow-up questionnaires were administered 3 and 6 months later.Results: Multilevel models using the couple as the unit of analysis showed that patients and partners who reported more frequent relationship talk had less distress (effect size r = 0.16) and greater marital adjustment over time (effect size r = 0.21), regardless of gender. Satisfaction with the frequency of relationship talk was associated with lower baseline distress for patients and partners (effect size r = 0.25). However, over time, greater communication regarding the relationship was related to less distress in the partner (effect size r = 0.15) than in the cancer patient.Discussion: Expanding the study of spousal communication in cancer beyond patient cancer-related disclosures to include the effects of talking about the spousal relationship may help clarify the role of relationship processes in couples' psychosocial adaptation. Patients and partners who begin talking about the relationship implications of lung cancer early on in their cancer experience may be better able to prepare together for the challenges they may face as cancer progresses and the patient moves toward the end-of-life.Implications For Cancer Survivors: Results of this study underscore the need for couple-focused interventions in lung cancer that address the communication and relationship needs of both partners. Working with couples during the initial diagnosis and treatment period and emphasizing the benefits of discussing relationship issues during this time of major upheaval may facilitate couples' successful adaptation to lung cancer.

OBJECTIVE: This article describes the use of a slightly modified version of the Eating Disorders Examination (EDE) in children. METHODS: Sixteen children aged between 7 and 14 years attending an eating disorders clinic over a 5-month period were recruited to the study. The two main modifications to the EDE were (A) the inclusion of a sort task to assess overvalued ideas about weight and shape and (B) the reformulation of certain items to assess intent rather than actual behavior. The existing EDE scoring system was used, resulting in item, subscale, and global scores. RESULTS: Of the 16 children (10 F 6 M), 11 had a diagnosis of anorexia nervosa, and 5 of eating disorder not otherwise specified (EDNOS). There were interesting differences in responses on items assessing core overvalued ideas, with weight and/or shape concerns emerging as of great importance in terms of self-evaluation in the majority of children with anorexia nervosa. DISCUSSION: Results suggest that this may be a useful assessment tool in children, with some children obtaining global and subscale scores consistent with adult norms for females with eating disorders. Problems of the administration of the EDE to this patient group are discussed and details of the modifications used are outlined. [ABSTRACT FROM AUTHOR]

Rat studies demonstrated that type II diabetes mellitus (T2DM) decreases both the production and bioavailability of nitric oxide (NO). L-arginine (LA) provides the precursor for the production of NO. We hypothesized that LA dietary supplementation will preserve NO production via endothelial nitric oxide synthase (eNOS) causing renal microvascular vasodilation and increased glomerular blood flow and thus increasing glomerular filtration rate (GFR). This would impede the formation of reactive oxygen species which contributes to cell damage and death. LA supplementation preserved GFR in the treated diabetic rats compared to untreated diabetic rats. We provide evidence that this effect may be due to increased levels of eNOS and urinary cyclic guanosine monophosphate, which leads to renal microvascular vasodilation. Plasma nitrotyrosine was decreased in the LA treated rats; however, plasma nitrite levels remained unaffected as expected. Marked improvements in glucose tolerance were also observed in the LA treated diabetic rats. These results demonstrate that LA supplementation preserves NO activity and may delay the onset of insulin resistance and renal dysfunction during hyperglycemic stress. These results suggest the importance of the NO pathway in consequent renal dysfunction and in the development of insulin resistance in diabetic rats.

Abstract Background Heart failure is a major cause of mortality and morbidity. As mortality rates are high, it is important that patients seen by general practitioners with symptoms suggestive of heart failure are identified quickly and treated appropriately. Identifying patients with heart failure or deciding which patients need further tests is a challenge. All patients with suspected heart failure should be diagnosed using objective tests such as echocardiography, but it is expensive, often delayed, and limited by the significant skill shortage of trained echocardiographers. Alternative approaches for diagnosing heart failure are currently limited. Clinical decision tools that combine clinical signs, symptoms or patient characteristics are designed to be used to support clinical decision-making and validated according to strict methodological procedures. The REFER Study aims to determine the accuracy and cost-effectiveness of our previously derived novel, simple clinical decision rule, a natriuretic peptide assay, or their combination, in the triage for referral for echocardiography of symptomatic adult patients who present in general practice with symptoms suggestive of heart failure. Methods/design This is a prospective, Phase II observational, diagnostic validation study of a clinical decision rule, natriuretic peptides or their combination, for diagnosing heart failure in primary care. Consecutive adult primary care patients 55 years of age or over presenting to their general practitioner with a chief complaint of recent new onset shortness of breath, lethargy or peripheral ankle oedema of over 48 hours duration, with no obvious recurrent, acute or self-limiting cause will be enrolled. Our reference standard is based upon a three step expert specialist consensus using echocardiography and clinical variables and tests. Discussion Our clinical decision rule offers a potential solution to the diagnostic challenge of providing a timely and accurate diagnosis of heart failure in primary care. Study results will provide an evidence-base from which to develop heart failure care pathway recommendations and may be useful in standardising care. If demonstrated to be effective, the clinical decision rule will be of interest to researchers, policy makers and general practitioners worldwide. Trial registration ISRCTN17635379

Abstract Background The aim of the present research is to conduct a fully powered explanatory trial to evaluate the efficacy of a brief self-regulation intervention to increase walking. The intervention will be delivered in primary care by practice nurses (PNs) and Healthcare Assistants (HCAs) to patients for whom increasing physical activity is a particular priority. The intervention has previously demonstrated efficacy with a volunteer population, and subsequently went through an iterative process of refinement in primary care, to maximise acceptability to both providers and recipients. Methods/ Design This two arm cluster randomised controlled trial set in UK general practices will compare two strategies for increasing walking, assessed by pedometer, over six months. Patients attending practices randomised to the self-regulation intervention arm will receive an intervention consisting of behaviour change techniques designed to increase walking self-efficacy (confidence in ability to perform the behaviour), and to help people translate their "good" intentions into behaviour change by making plans. Patients attending practices randomised to the information provision arm will receive written materials promoting walking, and a short unstructured discussion about increasing their walking. The trial will recruit 20 PN/HCAs (10 per arm), who will be trained by the research team to deliver the self-regulation intervention or information provision control intervention, to 400 patients registered at their practices (20 patients per PN/HCA). This will provide 85% power to detect a mean difference of five minutes/day walking between the self-regulation intervention group and the information provision control group. Secondary outcomes include health services costs, and intervention effects in sub-groups defined by age, ethnicity, gender, socio-economic status, and clinical condition. A mediation analysis will investigate the extent to which changes in constructs specified by the Theory of Planned Behaviour lead to changes in objectively assessed walking behaviour. Discussion This trial addresses the current lack of evidence for interventions that are effective at increasing walking and that can be offered to patients in primary care. The intervention being evaluated has demonstrated efficacy, and has been through an extensive process of adaptation to ensure acceptability to both provider and recipient, thus optimising fidelity of intervention delivery and treatment receipt. It therefore provides a strong test of the hypothesis that a self-regulation intervention can help primary care patients increase their walking.

Abstract Background Blood pressure (BP) lowering in people who have had a stroke or transient ischaemic attack (TIA) leads to reduced risk of further stroke. However, it is not clear what the target BP should be, since intensification of therapy may lead to additional adverse effects. PAST BP will determine whether more intensive BP targets can be achieved in a primary care setting, and whether more intensive therapy is associated with adverse effects on quality of life. Methods/Design This is a randomised controlled trial (RCT) in patients with a past history of stroke or TIA. Patients will be randomised to two groups and will either have their blood pressure (BP) lowered intensively to a target of 130 mmHg systolic, (or by 10 mmHg if the baseline systolic pressure is between 125 and 140 mmHg) compared to a standard group where the BP will be reduced to a target of 140 mmHg systolic. Patients will be managed by their practice at 1-3 month intervals depending on level of BP and followed-up by the research team at six monthly intervals for 12 months. 610 patients will be recruited from approximately 50 general practices. The following exclusion criteria will be applied: systolic BP The primary outcome will be change in systolic BP over twelve months. Secondary outcomes include quality of life, adverse events and cardiovascular events. In-depth interviews with 30 patients and 20 health care practitioners will be undertaken to investigate patient and healthcare professionals understanding and views of BP management. Discussion The results of this trial will inform whether intensive blood pressure targets can be achieved in people who have had a stroke or TIA in primary care, and help determine whether or not further research is required before recommending such targets for this population.

We report the case of a forty-nine year-old Native American female who presented with two-month history of headaches and unsteady gait. MRI brain showed a 6.5 cm by 5 cm enhancing dural-based mass with leftward midline shift. She was taken to the operating room for gross-total tumor resection. Pathology was supratentorial haemangioblastoma. This is the first known case of a supratentorial dural-based haemangioblastoma in a person of Native American descent. We review the literature and describe the unique characteristics of this tumor. [ABSTRACT FROM PUBLISHER]

Background: Patients with Barth syndrome (BTHS) can present with cardiomyopathy. BTHS subjects are at risk for cardiac adverse outcomes throughout life, including malignant arrhythmias and death. Electrocardiogram (ECG) parameters have never been assessed as a tool to predict adverse outcomes in individuals with BTHS., Objectives: The purpose of this study was to identify any ECG parameters including QRS fragmentation, presence of arrhythmia, or abnormal intervals that could predict adverse outcomes and cardiac death among the BTHS population., Methods: We performed a retrospective case referent study on subjects with BTHS (n=43), and compared them with our reference group, subjects with idiopathic dilated cardiomyopathy (DCM) from a single institution (n=53) from 2007-2021. BTHS data was obtained from subjects attending the biennial Barth Syndrome Foundation International Scientific, Medical, and Family Conferences (BSFISMFC) from 2002-2018. ECG data from first and last available ECG's prior to an adverse event or cardiac death was analyzed, and then multivariable regression was performed to determine odd ratios between ECG characteristics and adverse events/cardiac death., Results: No ECG variables were statistically significant predictors of adverse events or cardiac death in the BTHS group. Last ECG QRS fragmentation trended to statistically significance (OR 13.3, p=0.12) in predicting adverse events in the DCM group., Conclusion: No ECG parameters, including QRS fragmentation, presence of arrhythmia, or abnormal interval values predict adverse events or cardiac death among BTHS patients. QRS fragmentation may be a predictor of adverse events in the DCM population., Competing Interests: Declaration of Competing Interest: All authors report that they have no conflict of interests with this study.

Partial heart transplantation is a new approach to deliver growing heart valve implants. Partial heart transplants differ from heart transplants because only the part of the heart containing the necessary heart valve is transplanted. This allows partial heart transplants to grow, similar to the valves in heart transplants. However, the transplant biology of partial heart transplantation remains unexplored. This is a critical barrier to progress of the field. Without knowledge about the specific transplant biology of partial heart transplantation, children with partial heart transplants are empirically treated like children with heart transplants because the valves in heart transplants are known to grow. In order to progress the field, an animal model for partial heart transplantation is necessary. Here, we contribute our surgical protocol for partial heart transplantation in growing piglets. All aspects of partial heart transplantation, including the donor procedure, the recipient procedure, and recipient perioperative care are described in detail. There are important nuances in the conduct of virtually all aspects of open heart surgery that differs in piglets from humans. Our surgical protocol, which is based on our experience with 34 piglets, will allow other investigators to leverage our experience to seek fundamental knowledge about the nature of partial heart transplants. This is significant because the partial heart transplant model in piglets is complex and very resource intensive., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Domestic swine ( Sus scrofa domesticus ) are important translational models for cardiovascular transplant studies. This can be attributed to the anatomic and physiologic similarities of their cardiovascular system to humans. Transplant studies frequently employ clinically relevant immunosuppression regimens to prevent organ rejection postoperatively. Immunosuppression can lead to opportunistic infection, including presentations that are novel or poorly described in immunocompetent hosts. In this study, we describe the first case of Mycoplasma hyorhinis -induced endocarditis affecting the pulmonary valve in a juvenile, immunosuppressed pig following a partial heart transplantation procedure. Clinical signs of infection began at 15 d postoperation, were consistent with a variety of infectious agents, including Mycoplasma hyorhinis , and included lethargy, respiratory signs, and elevated white blood cell counts. By 28 d post procedure, lameness and soft tissue swelling around the left tarsus developed. Joint fluid obtained by arthrocentesis was PCR positive for Mycoplasma hyorhinis and negative for other tested pathogens. Despite antimicrobial treatment, the transplanted pulmonary valve developed leaflet thickening, stenosis, and insufficiency starting at 30 d after the procedure. At 86 d posttransplantation, the pig reached experimental endpoints and was humanely euthanized for necropsy and histopathology. The pulmonary valve had numerous dark red vegetative expansions of all 3 leaflets. Postmortem testing of a vegetative lesion was positive for Mycoplasma hyorhinis , confirming the etiologic agent responsible for endocarditis. Mycoplasma hyorhinis -induced endocarditis of an orthotopic transplanted pulmonary valve has yet to be described in swine. This case report demonstrates that infections following immunosuppression may present with novel or undercharacterized clinical signs.

Society is largely shaped by creativity, making it critical to understand why, despite minimal mean gender differences in creative ability, substantial differences exist in the creative achievement of men and women. Although the greater male variability hypothesis (GMVH) in creativity has been proposed to explain women's underrepresentation as eminent creators, studies examining the GMVH are sparse and limited. This systematic review and meta-analysis were conducted to examine whether the GMVH in creativity can adequately explain the gender gap in creative achievement. We examined the GMVH in creativity, along with mean gender differences, in a range of indicators of creativity and across different sample characteristics and measurement approaches. Effect sizes ( k = 1,003) were calculated using information retrieved from 194 studies ( N = 68,525). Data were analyzed using three-level meta-analysis and metaregression and publication bias was evaluated using Egger's regression test and contour-enhanced funnel plots. Results revealed minimal gender differences overall, with a slight mean advantage for females ( g = -0.10, 95% CI [-0.13, -0.06]) and a trivial variability advantage for males (lnVR = 0.02, 95% CI [0.004, 0.04]) in creative ability scores. However, the magnitude of the effect sizes was moderated by creative domain, task type, scoring type, and study region for mean differences and by country-level gender egalitarianism values for variability. Taken together, gender differences in the mean and variability of creative ability scores are minimal and inconsistent across different contexts, suggesting that the GMVH may not provide much explanatory power for the gender gap in creative achievement.

Background: To investigate associations between interpregnancy intervals (IPIs) and adverse birth outcomes in twin pregnancies., Methods: This retrospective cohort study of 9,867 twin pregnancies in Western Australia from 1980-2015. Relative Risks (RRs) were estimated for the interval prior to the pregnancy (IPI) as the exposure and after the pregnancy as a negative control exposure for preterm birth (< 37 weeks), early preterm birth (< 34 weeks), small for gestational age (SGA: < 10 th percentile of birth weight by sex and gestational age) and low birth weight (LBW: birthweight < 2,500 g)., Results: Relative to IPIs of 18-23 months, IPIs of < 6 months were associated with a higher risk of early preterm birth (aRR 1.41, 95% CI 1.08-1.83) and LBW for at least one twin (aRR 1.16, 95% CI 1.06-1.28). IPIs of 6-11 months were associated with a higher risk of SGA (aRR 1.24, 95% CI 1.01-1.54) and LBW for at least one twin (aRR 1.09, 95% CI 1.01-1.19). IPIs of 60-119 months and ≥ 120 months were associated with an increased risk of preterm birth (RR 1.12, 95% CI 1.03-1.22; and (aRR 1.25, 95% CI 1.10-1.41, respectively), and LBW for at least one twin (aRR 1.17, 95% CI 1.08-1.28; and aRR 1.20, 95% CI 1.05-1.36, respectively). IPIs of ≥ 120 months were also associated with an increased risk of early preterm birth (aRR 1.42, 95% CI 1.01-2.00). After negative control analysis, IPIs ≥ 120 months remained associated with early preterm birth and LBW., Conclusion: Evidence for adverse associations with twin birth outcomes was strongest for long IPIs., (© 2024.

Background & Aims: Reversion-inducing cysteine-rich protein with Kazal motifs (RECK) is an extracellular matrix regulator with anti-fibrotic effects. However, its expression and role in metabolic dysfunction-associated steatohepatitis (MASH) and hepatic fibrosis are poorly understood., Methods: We generated a novel transgenic mouse model with RECK overexpression specifically in hepatocytes to investigate its role in Western diet (WD)-induced liver disease. Proteomic analysis and in vitro studies were performed to mechanistically link RECK to hepatic inflammation and fibrosis., Results: Our results show that RECK expression is significantly decreased in liver biopsies from human patients diagnosed with MASH and correlated negatively with severity of metabolic dysfunction-associated steatotic liver disease (MASLD) and fibrosis. Similarly, RECK expression is downregulated in WD-induced MASH in wild-type mice. Hepatocyte-specific RECK overexpression significantly reduced hepatic pathology in WD-induced liver injury. Proteomic analysis highlighted changes in extracellular matrix and cell-signaling proteins. In vitro mechanistic studies linked RECK induction to reduced ADAM10 (a disintegrin and metalloproteinase domain-containing protein 10) and ADAM17 activity, amphiregulin release, epidermal growth factor receptor activation, and stellate cell activation., Conclusion: Our in vivo and mechanistic in vitro studies reveal that RECK is a novel upstream regulator of inflammation and fibrosis in the diseased liver, its induction is hepatoprotective, and thus highlights its potential as a novel therapeutic in MASH., (Copyright © 2024 The Authors.

Diet-induced obesity is implicated in the development of a variety of neurodegenerative disorders. Concurrently, the loss of mitochondrial Complex I protein or function is emerging as a key phenotype across an array of neurodegenerative disorders. Therefore, the objective of this study was to determine if Western diet (WD) feeding in swine [carbohydrate = 40.8% kCal (17.8% of total calories from high fructose corn syrup), protein = 16.2% kcal, fat = 42.9% kCal, and 2% cholesterol] would result in Complex I syndrome pathology. To characterize the effects of WD-induced obesity on brain mitochondria in swine, high resolution respirometry measurements from isolated brain mitochondria, oxidative phosphorylation Complex expression, and indices of oxidative stress and mitochondrial biogenesis were assessed in female Ossabaw swine fed a WD for 6-months. In line with Complex I syndrome, WD feeding severely reduced State 3 Complex I, State 3 Complex I and II, and uncoupled mitochondrial respiration in the hippocampus and prefrontal cortex (PFC). State 3 Complex I mitochondrial respiration in the PFC inversely correlated with serum total cholesterol. WD feeding also significantly reduced protein expression of oxidative phosphorylation Complexes I-V in the PFC. WD feeding significantly increased markers of antioxidant defense and mitochondrial biogenesis in the hippocampi and PFC. These data suggest WD-induced obesity may contribute to Complex I syndrome pathology by increasing oxidative stress, decreasing oxidative phosphorylation Complex protein expression, and reducing brain mitochondrial respiration. Furthermore, these findings provide mechanistic insight into the clinical link between obesity and mitochondrial Complex I related neurodegenerative disorders., Competing Interests: AC was employed by Medtronic PLC. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Kelty, Taylor, Wieschhaus, Thorne, Amin, Mueller, Olver, Tharp, Emter, Caulk and Rector.)

Objective: We aimed to investigate the clinical utility of follow-up oesophagogastroduodenoscopy (OGD2) in patients with severe oesophagitis (Los Angeles grades C or D) through evaluating the yield of Barrett's oesophagus (BO), cancer, dysplasia and strictures. Second, we aimed to determine if the Clinical Frailty Scale (CFS) may be used to identify patients to undergo OGD2s., Design/method: Patients in NHS Lothian with an index OGD (OGD1) diagnosis of severe oesophagitis between 1 January 2014 and 31 December 2015 were identified. Univariate analysis identified factors associated with grade. Patients were stratified by frailty and a diagnosis of stricture, cancer, dysplasia and BO., Results: In total 964 patients were diagnosed with severe oesophagitis, 61.7% grade C and 38.3% grade D. The diagnostic yield of new pathology at OGD2 was 13.2% (n=51), new strictures (2.3%), dysplasia (0.5%), cancer (0.3%) and BO (10.1%). A total of 140 patients had clinical frailty (CFS score ≥5), 88.6% of which were deceased at review (median of 76 months). In total 16.4% of frail patients underwent OGD2s and five new pathologies were diagnosed, none of which were significantly associated with grade. Among non-frail patients at OGD2, BO was the only pathology more common (p=0.010) in patients with grade D. Rates of cancer, dysplasia and strictures did not vary significantly between grades., Conclusion: Our data demonstrate that OGD2s in patients with severe oesophagitis may be tailored according to clinical frailty and only be offered to non-frail patients. In non-frail patients OGD2s have similar pick-up rates of sinister pathology in both grades of severe oesophagitis., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

There is enormous variation in the extent to which fetal Zika virus (fZIKV) infection affects the developing brain. Despite the neural consequences of fZIKV infection observed in people and animal models, many open questions about the relationship between infection dynamics and fetal and infant development remain. To further understand how ZIKV affects the developing nervous system and the behavioral consequences of prenatal infection, we adopted a nonhuman primate model of fZIKV infection in which we inoculated pregnant rhesus macaques and their fetuses with ZIKV in the early second trimester of fetal development. We then tracked their health across gestation and characterized infant development across the first month of life. ZIKV-infected pregnant mothers had long periods of viremia and mild changes to their hematological profiles. ZIKV RNA concentrations, an indicator of infection magnitude, were higher in mothers whose fetuses were male, and the magnitude of ZIKV RNA in the mothers' plasma or amniotic fluid predicted infant outcomes. The magnitude of ZIKV RNA was negatively associated with infant growth across the first month of life, affecting males' growth more than females' growth, although for most metrics, both males and females evidenced slower growth rates as compared with control animals whose mothers were not ZIKV inoculated. Compared with control infants, fZIKV infants also spent more time with their mothers during the first month of life, a social behavior difference that may have long-lasting consequences on psychosocial development during childhood.

We developed a novel conceptualization of one component of creativity in narratives by integrating creativity theory and distributional semantics theory. We termed the new construct divergent semantic integration (DSI), defined as the extent to which a narrative connects divergent ideas. Across nine studies, 27 different narrative prompts, and over 3500 short narratives, we compared six models of DSI that varied in their computational architecture. The best-performing model employed Bidirectional Encoder Representations from Transformers (BERT), which generates context-dependent numerical representations of words (i.e., embeddings). BERT DSI scores demonstrated impressive predictive power, explaining up to 72% of the variance in human creativity ratings, even approaching human inter-rater reliability for some tasks. BERT DSI scores showed equivalently high predictive power for expert and nonexpert human ratings of creativity in narratives. Critically, DSI scores generalized across ethnicity and English language proficiency, including individuals identifying as Hispanic and L2 English speakers. The integration of creativity and distributional semantics theory has substantial potential to generate novel hypotheses about creativity and novel operationalizations of its underlying processes and components. To facilitate new discoveries across diverse disciplines, we provide a tutorial with code (osf.io/ath2s) on how to compute DSI and a web app ( osf.io/ath2s ) to freely retrieve DSI scores., (© 2022.

Ticks (Acari: Ixodidae) are major disease vectors globally making it increasingly important to understand how altered vertebrate communities in urban areas shape tick population dynamics. In urban landscapes of Australia, little is known about which native and introduced small mammals maintain tick populations preventing host-targeted tick management and leading to human-wildlife conflict. Here, we determined (1) larval, nymphal, and adult tick burdens on host species and potential drivers, (2) the number of ticks supported by the different host populations, and (3) the proportion of medically significant tick species feeding on the different host species in Northern Sydney. We counted 3551 ticks on 241 mammals at 15 sites and found that long-nosed bandicoots (Perameles nasuta) hosted more ticks of all life stages than other small mammals but introduced black rats (Rattus rattus) were more abundant at most sites (33%-100%) and therefore important in supporting larval and nymphal ticks in our study areas. Black rats and bandicoots hosted a greater proportion of medically significant tick species including Ixodes holocyclus than other hosts. Our results show that an introduced human commensal contributes to maintaining urban tick populations and suggests ticks could be managed by controlling rat populations on urban fringes., (© 2023 The Authors.

Background and Purpose: In spine neurosurgery practice, patient-reported outcome measures (PROMs) are tools used to convey information about a patient's health experience and are an integral component of a clinician's decision-making process as they help guide treatment strategies to improve outcomes and minimize pain. Currently, there is limited research showing effective integration strategies of PROMs into electronic medical records. This study aims to provide a framework for other healthcare systems by outlining the process from start to finish in seven Hartford Healthcare Neurosurgery outpatient spine clinics throughout the state of Connecticut., Methods: On March 1, 2021, a pilot implementation program began in one clinic and on July 1, 2021, all outpatient clinics were implementing the revised clinical workflow that included the electronic collection of PROMs within the electronic health record (EHR). A retrospective chart analysis studied all adult (18+) new patient visits in seven outpatient clinics by comparing the rates of PROMs collection in Half 1 (March 1, 2021-August 31, 2022) and in Half 2 (September 1, 2022-February 28, 2022) across all sites. Additionally, patient characteristics were studied to identify any variables that may lead to higher rates of collection., Results: During the study period, 3528 new patient visits were analyzed. There was a significant change in rates of PROMs collection across all departments between H1 and H2 (p < 0.05). Additional significant predictors for PROMs collection were the sex and ethnicity of the patient as well as the provider type for the visit (p < 0.05)., Conclusions: This study proved that implementing the electronic collection of PROMs into an already existing clinical workflow reduces previously identified collection barriers and enables PROMs collection rates that meet or exceed current benchmarks. Our results provide a successful step-by-step framework for other spine neurosurgery clinics to implement a similar approach., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Venous sinus stenting (VSS) for medically refractory idiopathic intracranial hypertension (IIH) is emerging as a safe and effective alternative to shunting. However, stent navigation past the jugular bulb with commonly used carotid stenting systems via femoral access in cases with tortuous venous anatomy can present a challenge, leading to procedural failure. We present a technical refinement using a cervical access and peripheral vascular stent with a more stable 0.035-in. delivery platform as an alternative to the traditional approach to simplify the procedure and overcome the technical difficulties in cases with tortuous venous anatomy. Our institutional database for patients who had IIH and undergone VSS using the peripheral vascular stent between 2013 and 2023 was retrospectively reviewed. Data on 36 patients (33 women, 3 men, mean age 32 years) was collected. VSS was technically successful in all patients (100%) without major complications or thrombosis. There was one case of minor neck cellulitis treated with oral antibiotics. Three patients underwent repeat stenting, and 2 patients had ventriculoperitoneal shunt placement after stenting due to persistent or recurrent symptoms. All patients (100%) had improvement or resolution of papilledema; however, six patients had evidence of optic atrophy and persistent vision loss. Headache was resolved or improved in 91% of patients. In the presence of tortuous venous anatomy, VSS using cervical access and a peripheral vascular stent with a more stable 0.035-in. delivery platform can be considered as a safe and effective alternative approach with shorter procedure time. This approach is particularly advantageous in situations where the procedure is prolonged or high dose of contrast has been administered due to the technical challenges associated with the traditional use of carotid systems via femoral access for stent delivery., (© 2023.

NHANES needs urgent attention to ensure its future, which is facing emerging challenges associated with data collection, stagnant funding that has undercut innovation, and the increased call for granular data for subpopulations and groups at risk. The concerns do not rest merely on securing more funding but focus on the need for a constructive review of the survey to explore new approaches and identify appropriate change. This white paper, developed under the auspices of the ASN's Committee on Advocacy and Science Policy (CASP), is a call to the nutrition community to advocate for and support activities to prepare NHANES for future success in a changing nutrition world. Furthermore, because NHANES is much more than a nutrition survey and serves the needs of many in health fields and even commercial arenas, effective advocacy must be grounded in alliances among the survey's diverse stakeholders so that the full range of expertise and interests can engage. This article highlights the complicated nature of the survey along with key overarching challenges to underscore the importance of a measured, thoughtful, comprehensive, and collaborative approach to considering the future of NHANES. Starting-point questions are identified for the purposes of focusing dialog, discussion forums, and research. In particular, the CASP calls for a National Academies of Sciences, Engineering, and Medicine study on NHANES to articulate an actionable framework for NHANES going forward. With a well-informed and integrated set of goals and recommendations that could be provided by such a study, a secure future for NHANES is more readily achievable., (Copyright © 2023 American Society for Nutrition.

Background: Several national organizations have issued calls for academic nursing to create inclusive environments. Inclusive environments are needed given the vast inequities that plague the demography of nursing coupled with the need to serve diverse populations., Method: This article describes one school's journey toward inclusive excellence. A framework and infrastructure were developed detailing the strategy to enable the school to move toward an environment that supports inclusive excellence., Results: The framework identified five priority areas to mobilize change: leadership for inclusive excellence, student service delivery and engagement, recruitment retention and advancement, community engagement, and research and scholarship in health equity, along with metrics and measures to monitor progress., Conclusion: Inclusive excellence is an ongoing journey rather than a destination that requires leadership commitment as well as faculty, staff, and student involvement to create a diverse environment where all individuals feel valued and respected.

Private lands are often critical for successful species conservation, and the US Fish and Wildlife Service has increasingly utilized voluntary Candidate Conservation Agreements with Assurances (CCAAs) as a strategy for promoting private land conservation. CCAAs, however, present a challenge where the FWS, with its history as a regulatory entity, must now engage landowners as conservation partners. There is a deep culture of distrust among landowners, who are often suspicious of engaging with the agency, making it necessary for the FWS to build trusting relationships. Furthermore, FWS decisions often face litigation in the courts, where they may be overturned. This creates a challenge for CCAAs, as the agency is pulled between landowner demands for greater flexibility and a court system that emphasizes rigid compliance to established rules and procedures. This study seeks to understand what factors influenced the flexibility of agency staff and officials as they navigate the process of negotiating CCAAs amidst these competing demands for accountability. Three cases of CCAA development are presented, each aiming to protect the habitat for the greater sage-grouse and ease the regulatory burden on ranching communities, should the grouse become a federally protected species. In addition to the well-documented need for trust-building and maintenance, the findings of the study highlight the importance of shared goals, the participation of trusted intermediary organizations, and as well as the meaningful support and investment of senior FWS leadership in exploring creative, innovative solutions., (© 2022.

Objective: To compare well-baby visit and vaccination schedule adherence up to age 24 months in children of mothers with versus without schizophrenia., Methods: Using administrative health data on births in Ontario, Canada (2012-2016), children of mothers with schizophrenia ( ICD-9 : 295; ICD-10 : F20/F25; DSM-IV schizophrenia or schizoaffective disorder) (n = 1,275) were compared to children without maternal schizophrenia (n = 520,831) on (1) well-baby visit attendance, including an enhanced well-baby visit at age 18 months, and (2) vaccine schedule adherence for diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type B (DTaP-IPV-Hib), and measles, mumps, rubella (MMR). Cox proportional hazard regression models were adjusted for each of maternal sociodemographics, maternal health, and child health characteristics in blocks and all together in a fully adjusted model., Results: About 50.3% of children with maternal schizophrenia had an enhanced 18-month well-baby visit versus 58.6% of those without, corresponding to 29.0 versus 33.9 visits/100 person-years (PY), a hazard ratio (HR) of 0.82 (95% CI, 0.76-0.89). The association was dampened after adjustment for maternal sociodemographics, maternal health, and child health factors in blocks and overall, with a fully adjusted HR of 0.91 (95% CI, 0.84-0.98). Full vaccine schedule adherence occurred in 40.0% of children with maternal schizophrenia versus 46.0% of those without (22.6 vs 25.9/100 PY), yielding a HR of 0.86 (95% CI, 0.78-0.94). The association was dampened when adjusted for maternal sociodemographics and child health characteristics and became nonsignificant when adjusted for maternal health characteristics. The fully adjusted HR was 0.95 (95% CI, 0.87-1.04)., Conclusions: Increased efforts to ensure that children with maternal schizophrenia receive key early preventive health care services are warranted., (© Copyright 2023 Physicians Postgraduate Press, Inc.)

Congenital heart defects are the most common type of birth defects in humans and frequently involve heart valve dysfunction. The current treatment for unrepairable heart valves involves valve replacement with an implant, Ross pulmonary autotransplantation, or conventional orthotopic heart transplantation. Although these treatments are appropriate for older children and adults, they do not result in the same efficacy and durability in infants and young children for several reasons. Heart valve implants do not grow with the. Ross pulmonary autotransplants have a high mortality rate in neonates and are not feasible if the pulmonary valve is dysfunctional or absent. Furthermore, orthotopic heart transplants invariably fail from ventricular dysfunction over time. Therefore, the treatment of irreparable heart valves in infants and young children remains an unsolved problem. The objective of this single-arm, prospective study is to offer an alternative solution based on a new type of transplant, which we call "partial heart transplantation." Partial heart transplantation differs from conventional orthotopic heart transplantation because only the part of the heart containing the heart valve is transplanted. Similar to Ross pulmonary autotransplants and conventional orthotopic heart transplants, partial heart transplants contain live cells that should allow it to grow with the recipient child. Therefore, partial heart transplants will require immunosuppression. The risks from immunosuppression can be managed, as seen in conventional orthotopic heart transplant recipients. Stopping immunosuppression will simply turn the growing partial heart transplant into a non-growing homovital homograft. Once this homograft deteriorates, it can be replaced with a durable adult-sized mechanical implant. The protocol for our single-arm trial is described.

Introduction: There are concerns about microorganisms present on cannabis materials used in clinical settings by individuals whose health status is already compromised and are likely more susceptible to opportunistic infections from microbial populations present on the materials. Most concerning is administration by inhalation where cannabis plant material is heated in a vaporizer, aerosolized, and inhaled to receive the bioactive ingredients. Heating to high temperatures is known to kill microorganisms including bacteria and fungi; however, microbial death is dependent upon exposure time and temperature. It is unknown whether the heating of cannabis at temperatures and times designated by a commercial vaporizer utilized in clinical settings will significantly decrease the microbial loads in cannabis plant material., Methods: To assess this question, bulk cannabis plant material supplied by National Institute on Drug Abuse (NIDA) was used to assess the impact of heating by a commercial vaporizer. Initial method development studies using a cannabis placebo spiked with Escherichia coli were performed to optimize culture and recovery parameters. Subsequent studies were carried out using the cannabis placebo, low delta-9 tetrahydrocannabinol (THC) potency and high THC potency cannabis materials exposed to either no heat or heating for 30 or 70 seconds at 190°C. Phosphate-buffered saline was added to the samples and the samples agitated to suspend the microorganism. Microbial growth after no heat or heating was evaluated by plating on growth media and determining the total aerobic microbial counts and total yeast and mold counts., Results and Discussion: Overall, while there were trends of reductions in microbial counts with heating, these reductions were not statistically significant, indicating that heating using standard vaporization parameters of 70 seconds at 190°C may not eliminate the existing microbial bioburden, including any opportunistic pathogens. When cultured organisms were identified by DNA sequence analyses, several fungal and bacterial taxa were detected in the different products that have been associated with opportunistic infections or allergic reactions including Enterobacteriaceae , Staphylococcus, Pseudomonas , and Aspergillus ., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Sopovski, Han, Stevens-Riley, Wang, Erickson, Oktem, Vanlandingham, Taylor and Foley.)

Background: SYNJ1 encodes Synaptojanin-1, a dual-function poly-phosphoinositide phosphatase that is expressed in the brain to regulate neuronal synaptic vesicle dynamics. Biallelic SYNJ1 variants cause a spectrum of clinical manifestations, from early onset parkinsonism to developmental and epileptic encephalopathy., Methods: Proband-only exome sequencing was used to identify a homozygous SYNJ1 pathogenic variant in an individual with epileptic encephalopathy. Sanger sequencing was used to confirm the variant., Results: We present an Afro-Caribbean female who developed uncontrollable seizures shortly after birth, accompanied by developmental delay and severe generalized dystonia. She had homozygosity for a novel c.242-2A > G variant in SYNJ1 with both parents being heterozygous carriers. An older sister was reported to have had a similar presentation but was not examined. Both siblings died at an approximate age of 16 years., Conclusions: We report a novel pathogenic variant in SYNJ1 present in homozygosity leading to developmental and epileptic encephalopathy. Currently, there are only 4 reports describing 10 individuals with SYNJ1-related developmental and epileptic encephalopathy. This case expands the clinical knowledge and the allelic heterogeneity associated with SYNJ1 variants., (© 2022 The Authors. Molecular Genetics & Genomic Medicine published by Wiley Periodicals LLC.)
