Abstract

Background: Clinically useful biomaterials are derived from xenogeneic extracellular matrices, but extensive processes often used to remove all residual DNA are detrimental to their proper biological function. We hypothesized that deliberate and repeated injection of DNA extracted from clinically implantable, xenogeneic extracellular matrices might elicit an immune response in a well-established murine model that could ultimately lead to altered extracellular matrix remodeling. Methods: DNA was purified from unprocessed porcine extracellular matrices and processed extracellular matrices before sterilization (aseptic) and after sterilization. Groups of 10 mice were injected with these 3 purified DNAs and 3 controls: (1) DNA from E. coli; (2) DNA from unprocessed porcine extracellular matrices combined with interleukin-12 and methylated bovine serum albumin and emulsified in incomplete Freund's adjuvant; and (3) buffered saline. Immunizations occurred every 2 weeks for a total of 3 injections. Local cytokines and systemic anti-DNA antibodies were quantified 3 and 7 days after final injection. Results: The DNA extracted from unprocessed, aseptic, or sterilized porcine extracellular matrices failed to elicit a rejection response, and only with significant, proinflammatory adjuvant activation could such a response be seen. Without the adjuvants, biomaterial-derived DNA resulted in a mild accommodation cytokine response locally and no systemic anti-DNA antibody expression even at doses approximately 100-fold larger than would be clinically likely via extracellular matrix implantation. Conclusion: The immunological safety of porcine extracellular matrix biomaterials appears not to be related to DNA residues present. Such biomaterials need not be extensively processed, likely leading to detrimental changes in their bioactivity, solely in an effort to remove the mammalian DNA.

Abstract

OBJECTIVES Medical students are increasingly using a spaced repetition software called Anki to study. There are limited studies evaluating the relationship between Anki and learner outcomes. In this study, we describe the history of Anki use in medical school and assess the potential relationships between use of Anki and medical student academic, extracurricular, and wellness outcomes. METHODS We used cross-sectional data from a 50-item online survey and retrospective academic performance data from our institution's outcomes database. Participants were medical students. The survey assessed the frequency and timing of Anki use, student perceived stress, sleep quality, burnout risk, and involvement in extracurricular activities. Academic success was measured by USMLE Step 1 and Step 2 scores. RESULTS 165 students responded survey. 92 (56%) identified as daily Anki users. Daily Anki use was correlated with increased Step 1 score ( P = .039), but not Step 2 scores. There was an association between Anki use and increased sleep quality ( P = .01), but no difference for other measurements of wellness or extracurricular involvement. CONCLUSION The study demonstrates potential benefits of daily use of Anki but also confirms that a variety of study methods can be used to achieve similar medical school outcomes.

Abstract

Global warming is a major challenge to the sustainable and humane production of food because of the increased risk of livestock to heat stress. Here, the example of the prolactin receptor (PRLR) gene is used to demonstrate how gene editing can increase the resistance of cattle to heat stress by the introduction of mutations conferring thermotolerance. Several cattle populations in South and Central America possess natural mutations in PRLR that result in affected animals having short hair and being thermotolerant. CRISPR/Cas9 technology was used to introduce variants of PRLR in two thermosensitive breeds of cattle – Angus and Jersey. Gene‐edited animals exhibited superior ability to regulate vaginal temperature (heifers) and rectal temperature (bulls) compared to animals that were not gene‐edited. Moreover, gene‐edited animals exhibited superior growth characteristics and had larger scrotal circumference. There was no evidence for deleterious effects of the mutation on carcass characteristics or male reproductive function. These results indicate the potential for reducing heat stress in relevant environments to enhance cattle productivity. [ABSTRACT FROM AUTHOR]

Abstract

Massive blood transfusion (MBT) following older adult trauma poses unique challenges. Despite extensive evidence on optimal resuscitative strategies in the younger adult patients, there is limited research in the older adult population.We used the Trauma Quality Improvement Program (TQIP) database from 2013 to 2017 to identify all patients over 65 years old who received a MBT. We stratified our population into six fresh-frozen plasma:packed red blood cell (FFP:pRBC) ratio cohorts (1:1, 1:2, 1:3, 1:4, 1:5, 1:6+). Our primary outcomes were 24-h and 30-day mortality. We constructed multivariable regression models with 1:1 group as the baseline and adjusted for confounders to estimate the independent effect of blood ratios on mortality.A total of 3134 patients met our inclusion criteria (median age 73 ± 7.6 years, 65% male). On risk-adjusted multivariable analysis, 1:1 FFP:pRBC ratio was independently associated with lowest 24-h mortality (1:2 odds ratio [OR] 1.60, 95% confidence interval [CI] 1.25-2.06, p 0.001) and 30-day mortality (1:2 OR 1.44, 95% CI 1.15-1.80, p = 0.002).Compared to all other ratios, the 1:1 FFP:pRBC ratio had the lowest 24-h and 30-day mortality following older adult trauma consistent with findings in the younger adult population.

Abstract

Little geographical work has explored the role of hegemonic gay masculinity in constructing queer spaces and its impacts on multiply marginalized lesbian, gay, bisexual, transgender, queer, Two-Spirit, and additional (LGBTQ2+) people. Building on interviews with LGBTQ2+ youth experiencing homelessness, and photographs taken by them, this article investigates how hegemonic gay masculinity materializes in visual representations of gendered bodies throughout Toronto's gay village, and how this is reflected in feminine and trans or gender non-conforming (TGNC) youth's social experiences of the neighborhood. Through a framework of hegemonic masculinity, gender and race are understood as co-constitutive and read simultaneously in the queer geographical productions of gendered inclusions and exclusions among LGBTQ2+ youth experiencing homelessness. This article analyzes how hegemonic gay masculinity links queer spaces to various structures of power through visual cultures, including whiteness, cisnormativity, nationalism, and able-bodiedness, and the implications of this in the everyday social relations of feminine and TGNC youth experiencing homelessness. Through this exploration, this article presents how visual representations of gendered bodies communicate hegemonic masculinity in built queer environments, instruct varying forms of gendered and racialized inclusions and exclusions, and (re)produce a sense of unbelonging for some of the most marginalized members of the LGBTQ2+ community. Key Words: gay village, hegemonic masculinity, queer geographies, race, trans geographies. [ABSTRACT FROM AUTHOR]

Abstract

This paper examines the work-life challenges women entrepreneurs face and the consequences of such challenges on the management and growth of women’s enterprises in Ethiopia. Using a grounded theory approach, in-depth interviews with 31 women entrepreneurs operating in various sectors in Addis Ababa, Ethiopia were analyzed. The key finding of the study showed that women’s work-life role and the expectation to take the primary (sometimes the sole) responsibility to care and domestic responsibilities hampers their ability to grow and expand their businesses. Some of the women interviewed were found postponing their business growth decisions as a result of their care responsibilities at home. The challenge of growing their business was found to be acute for those women with pre-school children and with less familial and/or societal support to help shoulder care and other work-family responsibilities. However, we also found examples of women’s continued motivation as a resilience factor in making their business a success. Furthermore, the notion of business success is perceived to be much richer than economic business success. The study provides theoretical and practical insights to the field of (women) entrepreneurship and the work-family literature by exploring the relationship between the work-family roles and business growth in a less researched Sub-Saharan African country. Theoretically, the study contributes in providing partial explanation for the consistently reported but less explained phenomena of why women-headed enterprises remain small in size and less performing than men-owned business. It also questions looking at women’s entrepreneurships solely from their economic contribution to a country. It shows that their businesses operate at the intersection of gender, sex, family, culture, religion, institutions, and that they could be supported to contribute to family-community wellbeing as well as economic development.

Abstract

Abstract Impairment of left ventricular (LV) diastolic function is common amongst those with left heart disease and is associated with significant morbidity. Given that, in simple terms, the ventricle can only eject the volume with which it fills and that approximately one half of hospitalisations for heart failure (HF) are in those with normal/’preserved’ left ventricular ejection fraction (HFpEF) (Bianco et al. in JACC Cardiovasc Imaging. 13:258–271, 2020. 10.1016/j.jcmg.2018.12.035), where abnormalities of ventricular filling are the cause of symptoms, it is clear that the assessment of left ventricular diastolic function (LVDF) is crucial for understanding global cardiac function and for identifying the wider effects of disease processes. Invasive methods of measuring LV relaxation and filling pressures are considered the gold-standard for investigating diastolic function. However, the high temporal resolution of trans-thoracic echocardiography (TTE) with widely validated and reproducible measures available at the patient’s bedside and without the need for invasive procedures involving ionising radiation have established echocardiography as the primary imaging modality. The comprehensive assessment of LVDF is therefore a fundamental element of the standard TTE (Robinson et al. in Echo Res Pract7:G59–G93, 2020. 10.1530/ERP-20-0026). However, the echocardiographic assessment of diastolic function is complex. In the broadest and most basic terms, ventricular diastole comprises an early filling phase when blood is drawn, by suction, into the ventricle as it rapidly recoils and lengthens following the preceding systolic contraction and shortening. This is followed in late diastole by distension of the compliant LV when atrial contraction actively contributes to ventricular filling. When LVDF is normal, ventricular filling is achieved at low pressure both at rest and during exertion. However, this basic description merely summarises the complex physiology that enables the diastolic process and defines it according to the mechanical method by which the ventricles fill, overlooking the myocardial function, properties of chamber compliance and pressure differentials that determine the capacity for LV filling. Unlike ventricular systolic function where single parameters are utilised to define myocardial performance (LV ejection fraction (LVEF) and Global Longitudinal Strain (GLS)), the assessment of diastolic function relies on the interpretation of multiple myocardial and blood-flow velocity parameters, along with left atrial (LA) size and function, in order to diagnose the presence and degree of impairment. The echocardiographic assessment of diastolic function is therefore multifaceted and complex, requiring an algorithmic approach that incorporates parameters of myocardial relaxation/recoil, chamber compliance and function under variable loading conditions and the intra-cavity pressures under which these processes occur. This guideline outlines a structured approach to the assessment of diastolic function and includes recommendations for the assessment of LV relaxation and filling pressures. Non-routine echocardiographic measures are described alongside guidance for application in specific circumstances. Provocative methods for revealing increased filling pressure on exertion are described and novel and emerging modalities considered. For rapid access to the core recommendations of the diastolic guideline, a quick-reference guide (additional file 1) accompanies the main guideline document. This describes in very brief detail the diastolic investigation in each patient group and includes all algorithms and core reference tables.

Abstract

Objective:The impact of food insecurity on mental health has not yet been examined in graduate students, a population widely considered at elevated risk for financial strain and negative mental health outcomes. This study aimed to derive initial prevalence estimates of food insecurity in a sample of current graduate students at a large state university and to elucidate the relationship between food insecurity and depression, anxiety and stress in this sample.Design:Cross-sectional online survey including the US Household Food Security Survey Module: Six-Item Short Form and the Depression, Anxiety, and Stress Scales (DASS-21).Setting:University in the northeastern region of the USA.Participants:Two hundred sixty-three graduate students.Results:In the present sample, 59·7 % of participants reported high/marginal food security, 18·5 % reported low food security and 21·8 % reported very low food security. Graduate students with very low food security reported significantly greater depression (η2 = 0·09), anxiety (η2 = 0·10) and stress (η2 = 0·10), compared with those with low food security and high food security (all P’s < 0·001).Conclusions:Food insecurity occurred in nearly half of the graduate students surveyed, and very low food security was associated with elevated levels of depression, anxiety and stress. Findings highlight the need to address food insecurity and associated elevated mental health problems present among graduate students.

Abstract

The prediction of a difficult cholecystectomy has traditionally been based on certain pre-operative clinical and imaging factors. Most of the previous literature reported small patient cohorts and have not used an objective measure of operative difficulty. The aim of this study was to develop a pre-operative score to predict difficult cholecystectomy, as defined by a validated intra-operative difficulty grading scale. Two cohorts from prospectively maintained databases of patients who underwent laparoscopic cholecystectomy were analysed: the CholeS Study (8755 patients) and a single surgeon series (4089 patients). Factors potentially predictive of difficulty were correlated to the Nassar intra-operative difficulty scale. A multivariable binary logistic regression analysis was then used to identify factors that were independently associated with difficult laparoscopic cholecystectomy, defined as operative difficulty grades 3 to 5. The resulting model was then converted to a risk score, and validated on both internal and external datasets. Increasing age and ASA classification, male gender, diagnosis of CBD stone or cholecystitis, thick-walled gallbladders, CBD dilation, use of pre-operative ERCP and non-elective operations were found to be significant independent predictors of difficult cases. A risk score based on these factors returned an area under the ROC curve of 0.789 (95% CI 0.773–0.806, p

Abstract

Paratuberculosis (Johne's disease) is an economically significant, infectious disease of ruminants caused by Mycobacterium avium subsp paratuberculosis, and characterized by progressive weight loss and nonresponsive diarrhea. Genetic factors have been associated with differences in host susceptibility to bovine paratuberculosis. Research has been aimed at detecting associations between susceptibility and polymorphisms at candidate genes with no definitive results. Several gene products are candidates for this association. Interferon gamma is an inducible cytokine with a crucial role in the innate host response to intracellular bacteria. Toll-like receptors are trans-membrane structures responsible for coordination of innate and adaptive immune responses. The SLC11A1 gene plays an important role in innate immunity, preventing bacterial growth in macrophages during the initial stages of infection. The objective of this candidate gene case-control study was to characterize the distribution of polymorphisms in three candidate genes related to the immune function; interferon gamma (BoIFNG), toll-like receptor 4 (TLR4), and solute carrier family 11 member1 (SLC11A1) genes, and test their association with paratuberculosis infection in cattle., American Association of Bovine Practitioners Proceedings of the Annual Conference, 2008

Abstract

BACKGROUND: Competitive gaming (or esports) is an emerging phenomenon with a field of over 454 million fans globally. Despite its tremendous popularity and commercial support, esports is not widely understood. It is also disregarded as a reputable or credible form of competition. The International Olympic Committee (IOC) contends that esports may be considered a sporting activity, but this is limited to the basis of its sedentary nature and poor governanceDISCUSSION: These authors present evidence to inform and clarify misconceptions surrounding esports among the broader scientific community. They also encourage researchers to engage in further work into the phenomenon of competitive gaming with regard to health and performance, resulting in a better understanding of esports and guiding its development as a credible, competitive entity

Abstract

Correlational research suggests that emotion regulation deficits, which are known risk factors for substance addictions, may also play a role in the development of problem behaviors such as excessive or maladaptive use of social networking sites (SNS). This study sought to experimentally assess the hypothesized emotion regulatory function of SNS use. 139 undergraduates (53.2% female) were randomized to view brief movie clips known to reliably induce positive (37.4%), negative (29.5%), or neutral mood (33.1%) and then to browse a SNS (46.8%) or control website (53.2%). Mood and subjective urge to access SNS and the Internet were assessed before and after viewing the movie clips and browsing the websites. Participants meeting criteria for “moderate” levels of disordered SNS use self-reported significantly greater deficits in emotion regulation (p = .02, ηp2 = 0.14). Increases in positive and negative affect following the mood induction were associated with a decrease in subjective urge to access SNS (r = −0.22, p = .02, r = −0.28, p = .002, respectively). Time spent browsing SNS resulted in significantly greater increases in self-reported positive affect, compared to the control website (p = .001, ηp2 = 0.09). We replicate previous findings of greater emotion regulation deficits in individuals endorsing problematic SNS use. Increased positive and negative affect resulted in decreased urge to access SNS, suggesting that social networking may primarily serve to counter low-arousal emotions like boredom. Data provide initial experimental evidence to support the hypothesized emotion regulatory function of SNS, with SNS exposure resulting in increased positive affect. Findings suggest that interventions targeting problematic SNS use should incorporate strategies for improved emotion regulation.
