Project C.O.R.E.: Coaching Opportunities with Real Experiences

Retention and graduation rates of VCU men of color (MOC) is significantly lower than white men and women of color. Due to demonstrated significant attrition occurring after the sophomore year, Project C.O.R.E. (Coaching Opportunities with Real Experiences) is proposed as a sophomore-focused program that builds upon an existing freshman course on professional development for MOC. While the first-year course introduces students to a VCU support network, Project C.O.R.E. aims to increase university retention by expanding the student support network to members of the local community. Students are paired with community coaches, predominantly VCU alumni, to enhance their career and life-skills development. This program provides continued community, guidance, and support to encourage MOC to continue on the path to graduation

Design of the PACIFIC study: A randomized controlled trial evaluating a novel treatment for adults with overweight and obesity.

The majority of adults in the United States have overweight or obesity which is associated with significant health and psychological consequences. Behavioral Weight Loss (BWL) is the current gold-standard weight-loss program for adults but recidivism rates continue to be disturbingly high. Given the health consequences of excess weight and the lack of long-term effectiveness of BWL, it is important to identify novel weight-loss programs. We developed the ROC (Regulation of Cues) program to reduce overeating through improvement in sensitivity to appetitive cues and decreased responsivity to external food cues. This study is a 4-arm randomized control trial designed to evaluate the efficacy of ROC, ROC combined with BWL, BWL alone and an active comparator over 24 months. Study recruitment completed in November 2017. Two hundred and seventy-one participants were randomized (mean age = 46.97 years; 82% female, mean BMI = 34.59; 20% Hispanic) and assessments were conducted at baseline, mid-treatment (6 months) and post-treatment (12 months). At this time, participants are completing 6- (18 months) and 12-month (24 months) follow-ups. Targeting novel mechanisms is critically important to improve weight-loss programs. Through this trial, we hope to identify treatments for adults with overweight and obesity to facilitate long-term weight loss and improved health

Developmental changes in upper airway dynamics

Normal children have a less collapsible upper airway in response to subatmospheric pressure administration (P-NEG) during steep than normal adults do, and this upper airway response appears to be modulated by the central ventilatory drive. Children have a greater ventilatory drive than adults. We, therefore, hypothesized that children have increased neuromotor activation of their pharyngeal airway during sleep compared with adults. As infants have few obstructive apneas during steep, we hypothesized that infants would have an upper airway that was resistant to collapse. We, therefore, compared the upper airway pressure-flow (V) relationship during sleep between normal infants, prepubertal children, and adults. We evaluated the upper airway response to 1) intermittent, acute P-NEG (infants, children, and adults), and 2) hypercapnia (children and adults). We found that adults had a more collapsible upper airway during sleep than either infants or children. the children exhibited a vigorous response to both P-NEG and hypercapnia during sleep (P < 0.01), whereas adults had no significant change. Infants had an airway that was resistant to collapse and showed a very rapid response to P-NEG. We conclude that the upper airway is resistant to collapse during sleep in infants and children. Normal children have preservation of upper airway responses to P-NEG and hypercapnia during sleep, whereas responses are diminished in adults. Infants appear to have a different pattern of upper airway activation than older children. We speculate that the pharyngeal airway responses present in normal children are a compensatory response for a relatively narrow upper airway.Johns Hopkins Univ, Eudowood Div Pediat Resp Sci, Baltimore, MD 21287 USAJohns Hopkins Univ, Div Oncol Biostat, Baltimore, MD 21287 USAUniversidade Federal de São Paulo, Escola Paulista Med, Dept Neurol & Internal Med, São Paulo, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, Dept Neurol & Internal Med, São Paulo, BrazilWeb of Scienc

Historical geography II: traces remain

The second report in this series turns to focus on the trace in relation to life-writing and biography in historical geography and beyond. Through attention to tracing journeys, located moments and listening to the presence of ghosts (Ogborn, 2005), this report seeks to highlight the range of different ways in which historical geographers have explored lives, deaths, and their transient traces through varied biographical terrains. Continuing to draw attention in historical geography to the darkest of histories, this piece will pivot on moments of discovering the dead to showcase the nuanced ways in which historical geography is opening doors into uncharted lives and unspoken histories

Farmer‐led badger vaccination in Cornwall: Epidemiological patterns and social perspectives

In the United Kingdom, the management of bovine tuberculosis (bTB) challenges the coexistence of people and wildlife. Control of this cattle disease is hindered by transmission of its causative agent, Mycobacterium bovis, between cattle and badgers Meles meles. Badger culling has formed an element of bTB control policy for decades, but current government policy envisions expanding badger vaccination. Farming leaders are sceptical, citing concerns that badger vaccination would be impractical and potentially ineffective. We report on a 4‐year badger vaccination initiative in an 11 km2 area which, atypically, was initiated by local farmers, delivered by scientists and conservationists, and co‐funded by all three. Participating landholders cited controversies around culling and a desire to support neighbours as their primary reasons for adopting vaccination. The number of badgers vaccinated per km2 (5.6 km−2 in 2019) exceeded the number culled on nearby land (2.9 km−2 in 2019), and the estimated proportion vaccinated (74%, 95% confidence interval [CI] 40%–137%) exceeded the 30% threshold predicted by models to be necessary to control M. bovis. Farmers were content with how vaccination was delivered, and felt that it built trust with wildlife professionals. The percentage of badgers testing positive for M. bovis declined from 16.0% (95% CI 4.5%–36.1%) at the start of vaccination to 0% (95% CI 0%–9.7%) in the final year. With neither replication nor unvaccinated controls, this small‐scale case study does not demonstrate a causal link between badger vaccination and bTB epidemiology, but it does suggest that larger‐scale evaluation of badger vaccination would be warranted. Farmers reported that their enthusiasm for badger vaccination had increased after participating for 4 years. They considered vaccination to have been effective, and good value for money, and wished to continue with it. Synthesis and applications: Although small‐scale, this case study suggests that badger vaccination can be a technically effective and socially acceptable component of bTB control. A wider rollout of badger vaccination is more likely if it is led by the farming community, rather than by conservationists or government, and is combined with scientific monitoring.

Repeat Placental Growth Factor-Based Testing in Women with Suspected Preterm Preeclampsia:A Stratified Analysis of the PARROT-2 Trial

BACKGROUND: PlGF (placental growth factor)-based testing reduces severe maternal adverse outcomes. Repeat PlGF-based testing is not associated with improved perinatal or maternal outcomes. This planned secondary analysis aimed to determine whether there is a subgroup of women who benefit from repeat testing. METHODS: Pregnant individuals with suspected preterm preeclampsia were randomized to repeat revealed PlGF-based testing, compared with usual care where testing was concealed. Perinatal and maternal outcomes were stratified by trial group, by initial PlGF-based test result, and by PlGF-based test type (PlGF or sFlt-1 [soluble fms-like tyrosine kinase-1]/PlGF ratio). RESULTS: A total of 1252 pregnant individuals were included. Abnormal initial PlGF-based test identified a more severe phenotype of preeclampsia, at increased risk of adverse maternal and perinatal outcomes. Repeat testing was not significantly associated with clinical benefit in women with abnormal initial results. Of women with a normal initial result, 20% developed preeclampsia, with the majority at least 3 to 4 weeks after initial presentation. Repeat test results were more likely to change from normal to abnormal in symptomatic women (112/415; 27%) compared with asymptomatic women (163/890; 18%). A higher proportion of symptomatic women who changed from normal to abnormal were diagnosed with preeclampsia, compared with asymptomatic women. CONCLUSIONS: Our results do not demonstrate evidence of the clinical benefit of repeating PlGF-based testing if the initial result is abnormal. Judicious use of repeat PlGF-based testing to stratify risk may be considered at least 2 weeks after a normal initial test result, particularly in women who have symptoms or signs of preeclampsia.

Disturbed sleep is associated with reduced verbal episodic memory and entorhinal cortex volume in younger middle-aged women with risk-reducing early ovarian removal

INTRODUCTION: Women with early ovarian removal (&lt;48 years) have an elevated risk for both late-life Alzheimer's disease (AD) and insomnia, a modifiable risk factor. In early midlife, they also show reduced verbal episodic memory and hippocampal volume. Whether these reductions correlate with a sleep phenotype consistent with insomnia risk remains unexplored.METHODS: We recruited thirty-one younger middleaged women with risk-reducing early bilateral salpingo-oophorectomy (BSO), fifteen of whom were taking estradiol-based hormone replacement therapy (BSO+ERT) and sixteen who were not (BSO). Fourteen age-matched premenopausal (AMC) and seventeen spontaneously peri-postmenopausal (SM) women who were ~10y older and not taking ERT were also enrolled. Overnight polysomnography recordings were collected at participants' home across multiple nights (M=2.38 SEM=0.19), along with subjective sleep quality and hot flash ratings. In addition to group comparisons on sleep measures, associations with verbal episodic memory and medial temporal lobe volume were assessed.RESULTS: Increased sleep latency and decreased sleep efficiency were observed on polysomnography recordings of those not taking ERT, consistent with insomnia symptoms. This phenotype was also observed in the older women in SM, implicating ovarian hormone loss. Further, sleep latency was associated with more forgetting on the paragraph recall task, previously shown to be altered in women with early BSO. Both increased sleep latency and reduced sleep efficiency were associated with smaller anterolateral entorhinal cortex volume.DISCUSSION: Together, these findings confirm an association between ovarian hormone loss and insomnia symptoms, and importantly, identify an younger onset age in women with early ovarian removal, which may contribute to poorer cognitive and brain outcomes in these women.</p

Recruitment strategies for sarcopenia trials – lessons from the LACE randomised controlled trial

Background: Sarcopenia is rarely diagnosed and is not recorded electronically in routine clinical care, posing challenges to trial recruitment. We describe the performance of four components of a strategy to efficiently recruit participants with sarcopenia to a trial of perindopril and/or leucine for sarcopenia: primary care vs. hospital recruitment, a comparison of central vs. local telephone pre-screening, performance of a questionnaire on physical function conducted as part of the pre-screening telephone call, and performance of bioimpedance measurement to identify low muscle mass. Methods: Hospital-based recruitment took place through inpatient and outpatient geriatric medicine services. Local research nurses reviewed medical notes and approached potentially eligible patients. Primary care recruitment reviewed primary care lists from collaborating practices, sending mailshots to patients aged 70 and over who were not taking angiotensin-converting enzyme inhibitors. Telephone pre-screening was conducted either by research nurses at each site or centrally by Tayside Clinical Trials Unit. The 10-point SARC-F questionnaire was used for pre-screening. De-identified recruitment information was held on a central electronic tracking system and analysed using SPSS. Bioimpedance was measured using the Akern BIA 101 system, with the Sergi equation used to estimate lean mass. Results: Fourteen UK sites recruited to the trial. The 1202 sets of notes in hospital-based care were reviewed at these sites; 7 participants (0.6% of total notes screened) were randomized. From primary care, 13 808 invitations were sent; 138 (1.0% of total invited) were randomized. 633/2987 primary care respondents were pre-screened centrally; the mean number of calls per respondent was 2.3. For 10 sites where central and local pre-screening could be compared, the conversion rate from pre-screening to randomization was 18/588 (3.1%) for centralized calls, compared with 73/1814 (4.0%) for local pre-screening calls (P = 0.29). A weak relationship was seen between higher (worse) SARC-F score at screening and lower likelihood of progression to randomization (r = −0.08, P = 0.03). Muscle mass estimates generated using the Sergi equation were systematically biased, and a recalibrated equation for bioimpedance-estimated muscle mass was derived. Conclusions: Primary care recruitment led to higher response rates and overall numbers randomized than hospital-based recruitment. Centralized pre-screening saved local research nurses' time but did not improve conversion to randomization. SARC-F did not help to target screening activity in this sarcopenia trial, and a recalibration of the equation for estimating muscle mass from bioimpedance measures may improve accuracy of the screening process

Increasing physical activity in postpartum multiethnic women in Hawaii: results from a pilot study

<p>Abstract</p> <p>Background</p> <p>Mothers of an infant are much less likely to exercise regularly compared to other women. This study tested the efficacy of a brief tailored intervention to increase physical activity (PA) in women 3–12 months after childbirth. The study used a pretest-posttest design. Sedentary women (n = 20) were recruited from a parenting organization. Half the participants were ethnic minorities, mean age was 33 ± 3.8, infants' mean age was 6.9 ± 2.4 months, 50% were primiparas, and mean body mass index was 23.6 ± 4.2.</p> <p>Methods</p> <p>The two-month intervention included telephone counseling, pedometers, referral to community PA resources, social support, email advice on PA/pedometer goals, and newsletters.</p> <p>The primary outcome of the study was minutes per week of moderate and vigorous leisure-time physical activity measured by the Godin physical activity instrument.</p> <p>Results</p> <p>All women (100%) returned for post-test measures; thus, paired t-tests were used for pre-post increase in minutes of moderate and vigorous leisure-time physical activity and comparisons of moderate and vigorous leisure-time physical activity increases among ethnic groups. At baseline participants' reported a mean of 3 ± 13.4 minutes per week moderate and vigorous leisure-time physical activity. At post-test this significantly increased to 85.5 ± 76.4 minutes per week of moderate and vigorous leisure-time physical activity (p < .001, Cohen's d = 2.2; effect size r = 0.7). There were no differences in pre to post increases in minutes of moderate and vigorous leisure-time physical activity among races.</p> <p>Conclusion</p> <p>A telephone/email intervention tailored to meet the needs of postpartum women was effective in increasing physical activity levels. However, randomized trials comparing tailored telephone and email interventions to standard care and including long-term follow-up to determine maintenance of physical activity are warranted.</p
