Predicting Graduation from an Associate Degree Nursing Program Using Performance in Biology Coursework

This retrospective quantitative study focused on two cohorts of associate degree nursing (ADN) students who started coursework in 2014 and 2015. Data consisted of demographics, high school grade point average (HSGPA), grades in biology courses, graduation status, and whether biology courses were completed prior to the start of the nursing program. Multivariable logistic regression modeling was performed to determine which, if any, of the demographic and academic variables were predictors of on-time graduation. Of the variables, minority race, grades in BIO 210, HSGPA, and completing biology courses prior to starting the ADN program were predictors of on-time graduation. The results of this study should be used to target at-risk students, improve student performance in BIO 210, and advise students to complete biology courses prior to starting the ADN program

Trends in Memory Problems and Race/Ethnicity in the National Health and Examination Survey, 1999-2014.

BackgroundLittle data exist to describe serial population-level trends in cognitive impairment- especially among minority communities. Because memory problems are among the first warning signs of cognitive impairment, they provide a potential method for monitoring changes in cognitive health at the population level. This exploratory study aimed to: 1) estimate prevalence of memory problems among US residents by race/ethnicity, age category; and 2) examine whether racial/ethnic differences in subjective cognitive concerns (memory problems) varied across recent time periods.Design and settingSerial cross-sectional analysis of self-reported data from the National Health and Examination Survey (NHANES), 1999-2014.Participants20,585 participants aged ≥45 years during 1999-2014, who reported race/ethnicity as non-Hispanic White (NHW), non-Hispanic Black (NHB), and Latino/Hispanic.MeasurementsThe outcome of interest was subjective cognitive concerns, identified as self-reported memory problems. The frequencies of memory problems were examined for each 4-year period, across racial/ethnic groups.ResultsIn adjusted analyses, compared with older (aged ≥ 65 years) NHWs, disparities in subjective cognitive concerns were observed for older Latinos for most periods (range of AOR: 1.43 - 2.01, P<.05). Additionally, Latinos without a high school education had significantly higher odds of reporting memory problems than NHW in multiple periods (range of AOR: 1.95 - 2.17, P<.005), while Latino high school graduates did not. There were no significant changes in racial/ethnic differences in subjective cognitive concerns over time.ConclusionsThe prevalence of subjective cognitive concerns across time periods points to a need to engage patients - particularly older and less-educated Latinos - about warning signs for cognitive impairment. The impact of education on subjective cognitive concerns in older Latinos may be related to acculturation and warrant further investigation

Do automated digital health behaviour change interventions have a positive effect on self-efficacy? A systematic review and meta-analysis

© 2019 Taylor & Francis. This is an Accepted Manuscript of an article published by Taylor & Francis in Health Psychology Review on 20/01/2020, available online: https://doi.org/10.1080/17437199.2019.1705873.Self-efficacy is an important determinant of health behaviour. Digital interventions are a potentially acceptable and cost-effective way of delivering programmes of health behaviour change at scale. Whether behaviour change interventions work to increase self-efficacy in this context is unknown. This systematic review and meta-analysis sought to identify whether automated digital interventions are associated with positive changes in self-efficacy amongst non-clinical populations for five major health behaviours, and which BCTs are associated with that change. A systematic literature search identified 20 studies (n=5624) that assessed changes in self-efficacy and were included in a random effects meta-analysis. Interventions targeted: healthy eating (k=4), physical activity (k=9), sexual behaviour (k=3), and smoking (k=4). No interventions targeting alcohol use were identified. Overall, interventions had a small, positive effect on self-efficacy (푔 = 0.190, CI [0.078; 0.303]). The effect of interventions on self-efficacy did not differ as a function of health behaviour type (Qbetween = 7.3704 p = 0.061, df = 3). Inclusion of the BCT ‘information about social and environmental consequences’ had a small, negative effect on self-efficacy (Δ푔= - 0.297, Q=7.072, p=0.008). Whilst this review indicates that digital interventions can be used to change self-efficacy, which techniques work best in this context is not clear.Peer reviewedFinal Accepted Versio

Thalamocortical connectivity in major depressive disorder

Background: Major Depressive Disorder (MDD) is highly prevalent and potentially devastating, with widespread aberrations in brain activity. Thalamocortical networks are a potential candidate marker for psychopathology in MDD, but have not yet been thoroughly investigated. Here we examined functional connectivity between major cortical areas and thalamus. Method: Resting-state fMRI from 54 MDD patients and 40 healthy controls were collected. The cortex was segmented into six regions of interest (ROIs) consisting of frontal, temporal, parietal, and occipital lobes and pre-central and post-central gyri. BOLD signal time courses were extracted from each ROI and correlated with voxels in thalamus, while removing signals from every other ROI. Results: Our main findings showed that MDD patients had predominantly increased connectivity between medial thalamus and temporal areas, and between medial thalamus and somatosensory areas. Furthermore, a positive correlation was found between thalamo-temporal connectivity and severity of symptoms. Limitations: Most of the patients in this study were not medication naïve and therefore we cannot rule out possible long-term effects of antidepressant use on the findings. Conclusion: The abnormal connectivity between thalamus and temporal, and thalamus and somatosensory regions may represent impaired cortico-thalamo-cortical modulation underlying emotional, and sensory disturbances in MDD. In the context of similar abnormalities in thalamocortical systems across major psychiatric disorders, thalamocortical dysconnectivity could be a reliable transdiagnostic marker

Solution structure of a bacterial microcompartment targeting peptide and its application in the construction of an ethanol bioreactor

Targeting of proteins to bacterial microcompartments (BMCs) is mediated by an 18-amino-acid peptide sequence. Herein, we report the solution structure of the N-terminal targeting peptide (P18) of PduP, the aldehyde dehydrogenase associated with the 1,2-propanediol utilization metabolosome from Citrobacter freundii. The solution structure reveals the peptide to have a well-defined helical conformation along its whole length. Saturation transfer difference and transferred NOE NMR has highlighted the observed interaction surface on the peptide with its main interacting shell protein, PduK. By tagging both a pyruvate decarboxylase and an alcohol dehydrogenase with targeting peptides, it has been possible to direct these enzymes to empty BMCs in vivo and to generate an ethanol bioreactor. Not only are the purified, redesigned BMCs able to transform pyruvate into ethanol efficiently, but the strains containing the modified BMCs produce elevated levels of alcohol

Management and Rehabilitation Strategies Following IED Related Mild Traumatic Brain Injury in Civilian Settings - What to Expect and How to Optimize Recovery From mTBI

The wide array of psychological and physical responses following an IED bombing may reduce the likelihood that appropriate assessment and recovery from mTBI occur. Such a situation is problematic as mTBI itself may negatively influence the recovery from the traumatic event or associated injuries if not diagnosed and managed properly. Consequently, the overall aim of this article is to better inform healthcare practitioners, patients, and patients’ social support networkabout the nature of IED-related mild traumatic brain injuries. In so doing, we hope to facilitate enhanced assessment, management, and rehabilitation of this injury. In particular, the specific goals of the review include: (i) a description of the nature of an IED-related mTBI in a civilian setting (section 2 to 2.3); (ii) a description of the unique circumstances for mTBI survivors in regards to the signs and symptoms that may be anticipated (section 2.4); (iii) what key stakeholders including: the rehabilitant, the managing health care team, and social support providers (e.g., family members) can expect in terms of the physical and emotional recovery process (sections 3 to 4.4.) Finally, general and specific lifestyle modifications to improve survivors’ health are described in order to lay a clear foundation for patients’ recovery from an IED-related mTBI

Diagnosis and Monitoring of White Coat Hypertension in Pregnancy:an ISSHP Consensus Delphi Procedure

BACKGROUND: There is no accepted definition or standardized monitoring for white coat hypertension in pregnancy. This Delphi procedure aimed to reach consensus on out-of-office blood pressure (BP) monitoring, and white coat hypertension diagnostic criteria and monitoring. METHOD: Relevant international experts completed three rounds of a modified Delphi questionnaire. For each item, the predefined cutoff for group consensus was ≥70% agreement, with 60% to 70% considered to warrant reconsideration at the subsequent round, and <60% considered insufficient to warrant consideration. RESULTS: Of 230 experts, 137 completed the first round and 114 (114/137, 83.2%) completed all three. For out-of-office BP monitoring, there was consensus that home BP monitoring (HBPM) should be chosen; instructions given, pairs of BP values taken, opportunity given for women to qualify values they do not regard as valid, and BP considered evaluated when ≥25% of values are above a cutoff. For HBPM, BP should be taken at least 2 to 3 d/wk, at minimum in the morning; however, many factors may affect frequency and timing. Experts endorsed a clinic BP <140/90 mm Hg as normal. While not reaching consensus, most agreed that HBPM values should be lower than clinic BP. Among those, HBPM <135/85 mm Hg was considered normal. There was consensus that white coat hypertension warrants: HBPM at least 1 d/wk before 20 weeks, 2 to 3 d/wk after 20 weeks or if persistent hypertension develops, and symptom monitoring (ie, headache, visual symptoms, and right upper quadrant/epigastric pain). CONCLUSIONS: Consensus-based diagnostic criteria and monitoring strategies should inform clinical care and research, to facilitate evaluation of out-of-office BP monitoring on pregnancy outcomes
