Do Canadians Support Tailored and Targeted Public Health Programs? A Discrete Choice Experiment

Background. We aimed to assess public support of tailored and targeted public health interventions for various marginalized communities.Methods. We conducted a discrete choice experiment using a web-based survey advertised to Facebook and Instagram users living in Canada, aged >16. Participants were asked to choose between funding two hypothetical public health programs. Each program was described by its purpose; expected increase in life expectancy; and target group. Demographically-weighted generalized linear mixed-effects models were constructed to identify program factors associated with program selection.Results. 23,889 exercises were completed by 3,054 participants. Selected programs were less likely to focus on prevention (vs. treatment). For each 1-year increase in the marginal years of life gained, there was a 15% increase in the odds of a program being selected. Interventions tailored to marginalized communities or targeting stigmatized health conditions were less likely to be selected compared with interventions targeted to the general population or targeting chronic health conditions. Noteworthy exceptions included an increased preference for interventions aligning with the perceived needs of marginalized communities (e.g. HIV and men who have sex with men).Conclusions. Stigmatizing perceptions of health conditions and key populations likely influence public health programming preferences of Canadians. Informational campaigns highlighting disparities experienced by marginalized populations may improve support for targeted and tailored interventions.

Multi-year Use of the Standard Gauge Railway Underpasses by Mammals in Tsavo, Kenya: Influence of Underpass Dimensions, Infrastructure and Ecology

Rail and road infrastructure is essential for economic growth and development but can cause a gradual loss in biodiversity and degradation of ecosystem function and services. We assessed influence of underpass dimensions, fencing, proximity to water and roads, Normalized Difference Vegetation Index (NDVI), presence of other species and livestock on underpass use by large and medium-sized mammals. Results revealed hyenas and leopards used the underpasses more than expected whereas giraffes and antelopes used the underpasses less than expected. Generalized linear mixed effects models (GLMMs) revealed that underpass height influenced their use by wildlife, with several species preferring to use taller underpasses. Electric fencing increased underpass use by funneling species towards underpasses, except for elephants and black-backed jackal for which it reduced underpass passage. GLMMs also revealed that the use of underpasses by livestock reduced the probability of their use by nearly 50% of wildlife species. Carnivore species were more likely to cross underpasses used by their prey. Buffalo, livestock, and hyenas used underpasses with higher NDVI and near water sources while baboons, dik-diks and antelope avoided underpasses with high NDVI. The findings suggest a need for diverse, and comprehensive approach for mitigating the negative impacts of rail on African wildlife.

Association of ABO Blood Type with Bleeding Severity in Patients with Acute Gastroesophageal Variceal Bleeding

Background and Objectives: ABO blood types have been implicated as potential risk factors for various hemorrhagic diseases. No study has investigated the association between gastroesophageal variceal bleeding and ABO blood types. We aimed to evaluate the impact of ABO blood types on mortality and bleeding risk in acute gastroesophageal variceal bleeding. Materials and Methods: This is a retrospective observational study. Patients presenting with acute gastroesophageal varices bleeding diagnosed by endoscopy were enrolled, and were divided by blood type into a type O group and non-type O group. The outcomes were death within 30 days and the proportion of further bleeding. We used generalized linear mixed-effects models to analyze the outcomes. Results: A total of 327 patients and 648 records of emergency room visits were included. The 30-day mortality was 14.8% (21 of 142 patients) in the type O group, and 16.2% (30 of 185 patients) in the non-type O group (p = 0.532). Further bleeding within 30 days occurred in 34 cases (12.6%) in the type O group, and in 26 cases (6.9%) in the non-type O group (p = 0.539). Conclusions: There was no significant difference in blood transfusion volume in 24 h, recurrent bleeding rates, or mortality between patients with blood type O and those with non-type O.

Javan langur responses to the repeated exposure of ground survey and novel stimulus, unmanned aerial vehicles

The use of small Unmanned Aerial Vehicles (UAVs; a.k.a “drones”) for ecological monitoring, conservation campaign, and management is increasing enormously. UAVs operate at low altitudes (<150 m) and in any terrain; thus, they are susceptible to interact with local fauna, generating a new type of anthropogenic disturbance that has not been systematically evaluated. Both policy-makers and practitioners require data about the potential impacts of UAVs on natural biota, but few studies exist. The research aims to compare behavioral responses from ground-based surveys vs. UAVs flights. Moreover, we conducted two experiments of UAVs overflights, specifically aiming to assess the responses of Trachypithecus auratus. Between January and March 2021, we conducted 24 UAVs flight approaches and 12 ground surveys at Mount Halimun-Salak National Park, Indonesia. We applied generalized linear mixed-effects models and Kruskal-Wallis tests to 364 behavioral scores obtained from two independent observers. When directly compared, the detection time was higher using UAVs (χ2 = 38.50; df= 1; p < 0.050), and behavioral responses by Javan langur to UAVs overflights at > 30 m were different from responses to ground surveys were more intense. Finally, we suggest data-driven best practices for UAVs use and the design of future UAVs-wildlife response studies.

Identifying Practices to Promote Inpatient Adolescent and Influenza Vaccine Delivery

OBJECTIVES Many hospitalized children are underimmunized. We assessed the association between hospital immunization practices and tetanus, diphtheria, and acellular pertussis (Tdap), meningococcal, human papillomavirus (HPV), and influenza vaccine delivery. METHODS An electronic survey regarding hospital vaccine delivery practices was distributed via the Pediatric Health Information System (PHIS) and Pediatric Research in Inpatient Settings networks to PHIS hospitals. Number of vaccines delivered and total discharges in 2018 were obtained from the PHIS database to determine hospital vaccine delivery rates; patients 11 to 18 years old (adolescent vaccines) and 6 months to 18 years old (influenza vaccine) were included. Vaccine delivery rates were risk adjusted by using generalized linear mixed-effects modeling and compared with survey responses to determine associations between the number or presence of specific practices and vaccine delivery. Adjusted HPV and meningococcal vaccine delivery rates could not be calculated because of low delivery. RESULTS Twenty-nine hospitals completed a survey (57%). 152 499 and 423 046 patient encounters were included for the adolescent and influenza vaccines, respectively. Unadjusted inpatient vaccine delivery rates varied. After adjustment, the number of practices was associated only with influenza vaccine delivery (P = .02). Visual prompts (P = .02), nurse or pharmacist ordering (P = .003), and quality improvement projects (P = .048) were associated with increased influenza vaccine delivery; nurse or pharmacist ordering had the greatest impact. No practices were associated with Tdap vaccine delivery. CONCLUSIONS The number and presence of specific hospital practices may impact influenza vaccine delivery. Further research is needed to identify strategies to augment inpatient adolescent immunization.

Probiotics Improve Gastrointestinal Function and Life Quality in Pregnancy

We studied whether probiotics were beneficial for hormonal change-associated dysbiosis, which may influence the enteric nervous system and GI function during early pregnancy. The study was 16 days consisting of two cycles of six daily probiotics mainly Lactobacillus and 2 days without probiotics. Daily surveys were conducted to monitor GI function and life quality. A subset of the participants who contributed fecal specimens was used for microbiota metagenomic sequencing, metabolomics, and quantification of bacterial genes to understand potential underlying mechanisms. Statistical analyses were done by generalized linear mixed-effects models. Thirty-two obstetric patients and 535 daily observations were included. The data revealed that probiotic supplementation significantly reduced the severity of nausea, vomiting, constipation, and improved life quality. Moreover, a low copy number of fecal bsh (bile salt hydrolase), which generates free bile acids, was associated with high vomiting scores and probiotic intake increased fecal bsh. In exploratory analysis without adjusting for multiplicity, a low fecal α-tocopherol, as well as a high abundance of Akkemansia muciniphila, was associated with high vomiting scores and times, respectively. The potential implications of these biomarkers in pregnancy and GI function are discussed. Probiotics likely produce free bile acids to facilitate intestinal mobility and metabolism.

Accuracy of high-frequency oscillations recorded intraoperatively for classification of epileptogenic regions

To see whether acute intraoperative recordings using stereo EEG (SEEG) electrodes can replace prolonged interictal intracranial EEG (iEEG) recording, making the process more efficient and safer, 10 min of iEEG were recorded following electrode implantation in 16 anesthetized patients, and 1–2 days later during non-rapid eye movement (REM) sleep. Ripples on oscillations (RonO, 80–250 Hz), ripples on spikes (RonS), sharp-spikes, fast RonO (fRonO, 250–600 Hz), and fast RonS (fRonS) were semi-automatically detected. HFO power and frequency were compared between the conditions using a generalized linear mixed-effects model. HFO rates were compared using a two-way repeated measures ANOVA with anesthesia type and SOZ as factors. A receiver-operating characteristic (ROC) curve analysis quantified seizure onset zone (SOZ) classification accuracy, and the scalar product was used to assess spatial reliability. Resection of contacts with the highest rate of events was compared with outcome. During sleep, all HFOs, except fRonO, were larger in amplitude compared to intraoperatively (p < 0.01). HFO frequency was also affected (p < 0.01). Anesthesia selection affected HFO and sharp-spike rates. In both conditions combined, sharp-spikes and all HFO subtypes were increased in the SOZ (p < 0.01). However, the increases were larger during the sleep recordings (p < 0.05). The area under the ROC curves for SOZ classification were significantly smaller for intraoperative sharp-spikes, fRonO, and fRonS rates (p < 0.05). HFOs and spikes were only significantly spatially reliable for a subset of the patients (p < 0.05). A failure to resect fRonO areas in the sleep recordings trended the most sensitive and accurate for predicting failure. In summary, HFO morphology is altered by anesthesia. Intraoperative SEEG recordings exhibit increased rates of HFOs in the SOZ, but their spatial distribution can differ from sleep recordings. Recording these biomarkers during non-REM sleep offers a more accurate delineation of the SOZ and possibly the epileptogenic zone.

Secure Attachment Priming Amplifies Approach Motivation for Infant Faces Among Childless Adults

Existing studies have indicated that priming secure attachment alters adults’ neural responses to infant faces. However, no study has examined whether this effect exists for motivational behavioral responses, and none of the previous studies included adult faces as a baseline to determine whether the security prime enhances responses to human faces in general or infant faces alone. To address this limitation, the current study recruited 160 unmarried and childless adults in the first phase, and all of them completed a battery of questionnaires, including the Interest in Infants, the Experiences in Close Relationships (ECR), and State Adult Attachment Measure (SAAM). A week later, after priming, 152 (76 security-primed vs. 76 neutrally primed) participants completed the SAAM and a behavioral program assessing their motivational responses to both adult and infant faces (i.e., liking, representational, and evoked responses). A manipulation check showed that the security prime was effective. Then, generalized linear mixed-effects models (GLMMs) showed that security priming enhances adults’ liking, representational, and evoked responses (three components of the motivational system) only to infant faces and not to adult faces. Moreover, hierarchical regression analysis indicated that, even after security priming, there was a substantial linear relationship between positive motivation toward infant faces and the state of adult secure attachment. In summary, this study demonstrated for the first time that promoting the state of adult secure attachment can effectively enhance the effect size of the baby face schema. The current results were interpreted according to Bowlby’s view of the attachment behavioral system.

Treatment of Underlying Forms: A Bayesian Meta-Analysis of the Effects of Treatment and Person-Related Variables on Treatment Response

Purpose This meta-analysis synthesizes published studies using “treatment of underlying forms” (TUF) for sentence-level deficits in people with aphasia (PWA). The study aims were to examine group-level evidence for TUF efficacy, to characterize the effects of treatment-related variables (sentence structural family and complexity; treatment dose) in relation to the Complexity Account of Treatment Efficacy (CATE) hypothesis, and to examine the effects of person-level variables (aphasia severity, sentence comprehension impairment, and time postonset of aphasia) on TUF response. Method Data from 13 single-subject, multiple-baseline TUF studies, including 46 PWA, were analyzed. Bayesian generalized linear mixed-effects interrupted time series models were used to assess the effect of treatment-related variables on probe accuracy during baseline and treatment. The moderating influence of person-level variables on TUF response was also investigated. Results The results provide group-level evidence for TUF efficacy demonstrating increased probe accuracy during treatment compared with baseline phases. Greater amounts of TUF were associated with larger increases in accuracy, with greater gains for treated than untreated sentences. The findings revealed generalization effects for sentences that were of the same family but less complex than treated sentences. Aphasia severity may moderate TUF response, with people with milder aphasia demonstrating greater gains compared with people with more severe aphasia. Sentence comprehension performance did not moderate TUF response. Greater time postonset of aphasia was associated with smaller improvements for treated sentences but not for untreated sentences. Conclusions Our results provide generalizable group-level evidence of TUF efficacy. Treatment and generalization responses were consistent with the CATE hypothesis. Model results also identified person-level moderators of TUF (aphasia severity, time postonset of aphasia) and preliminary estimates of the effects of varying amounts of TUF for treated and untreated sentences. Taken together, these findings add to the TUF evidence and may guide future TUF treatment–candidate selection. Supplemental Material https://doi.org/10.23641/asha.16828630
