Health Communication as a Public Health Training and Workforce Development Issue

Effective communication is one of the core competencies for public health professionals and is required for local health department (LHD) accreditation. Public health communication specialists play a critical role as conduits of health information, particularly with regard to managing relationships with media and the message that is ultimately represented by news outlets. However, capacity for engagement with traditional media in community health improvement at the local level has not been well-described. As part of a larger study examining the use and impact of the County Health Rankings in North Carolina, LHD media staffing and interaction with traditional media were examined through a cross-sectional, online survey, administered to North Carolina LHDs. Results indicate that most LHDs in North Carolina have staff designated to work with media, but few have dedicated staff or staff with an educational background in mass communication. Most communication staff enter their position with less than one year of experience, though almost all receive some training once on the job. Press releases are issued relatively infrequently, which implies that media engagement and message management are underdeveloped at the local level. These results suggest that health communication specialists are underutilized in LHDs and these skills should be emphasized in LHD hiring practices and in public health workforce development

Transcranial electrical and magnetic stimulation (tES and TMS) for addiction medicine: A consensus paper on the present state of the science and the road ahead

There is growing interest in non-invasive brain stimulation (NIBS) as a novel treatment option for substance-use disorders (SUDs). Recent momentum stems from a foundation of preclinical neuroscience demonstrating links between neural circuits and drug consuming behavior, as well as recent FDA-approval of NIBS treatments for mental health disorders that share overlapping pathology with SUDs. As with any emerging field, enthusiasm must be tempered by reason; lessons learned from the past should be prudently applied to future therapies. Here, an international ensemble of experts provides an overview of the state of transcranial-electrical (tES) and transcranial-magnetic (TMS) stimulation applied in SUDs. This consensus paper provides a systematic literature review on published data – emphasizing the heterogeneity of methods and outcome measures while suggesting strategies to help bridge knowledge gaps. The goal of this effort is to provide the community with guidelines for best practices in tES/TMS SUD research. We hope this will accelerate the speed at which the community translates basic neuroscience into advanced neuromodulation tools for clinical practice in addiction medicine

Monothioarsenate Uptake, Transformation, and Translocation in Rice Plants

Thioarsenates form under sulfur-reducing conditions in paddy soil pore waters. Sulfur fertilization, recently promoted for decreasing total arsenic (As) grain concentrations, could enhance their formation. Yet, to date, thioarsenate toxicity, uptake, transformation, and translocation in rice are unknown. Our growth inhibition experiments showed that the toxicity of monothioarsenate (MTA) was similar to that of arsenate but lower than that of arsenite. Higher toxicity of MTA with lower phosphate availability might imply uptake through phosphate transporters similar to arsenate. To demonstrate direct uptake of MTA by rice plants, a species-preserving extraction method for plant samples was developed. When plants were exposed to 10 μM MTA for 72 h, up to 19% and 4% of total As accumulated in roots and shoots, respectively, was MTA. Monothioarsenate was detected in xylem sap and root exudates, and its reduction to arsenite in rice roots and shoots was shown. Total As uptake was lower upon exposure to MTA compared to arsenate, but root to shoot translocation was higher, resulting in comparable As shoot concentrations. Thus, before promoting sulfur fertilization, uptake and detoxifying mechanisms of thioarsenates as well as potential contribution to grain As accumulation need to be better understood

Factors influencing risky single occasion drinking in Canada and policy implications

Abstract Background Misuse of alcohol, including single risky occasion drinking (RSOD) is associated with a number of health, social and economic consequences. While research demonstrates that many factors contribute to individuals’ drinking practices, little is known about risk factors that contribute to RSOD in the Canadian population. The objectives of this study are to examine the patterns of RSOD in Canada, to identify factors associated with RSOD, and to explore policy implications. Methods The Canadian Community Health Survey (CCHS) 2009–2010 annual component was used to conduct all the analyses in this paper. We used two models: (1) a binary logistic regression model, and (2) a multinomial logistic regression model, to identify factors that were significantly associated with our dependent variables, RSOD engagement and frequency of RSOD, respectively. Results Daily smokers were 6.20 times more likely to engage in frequent RSOD than those who never smoke. Males were 4.69 times more likely to engage in risky RSOD. We also found significant associations between the frequency of RSOD and Province/Territory of residence, income and education, marital status and perceived health status. Finally, stress was associated with engaging in infrequent RSOD. Conclusions Our finding associating daily smoking with risk alcohol intake specifically suggests the possibility of combining public health interventions for both. The study findings also indicate that education is a protective factor, further supporting the role of education as a major determinant of health. The significant provincial variation we found also point to the need to study this issue further and understand the links between provincial level policies and RSOD

Immunogenicity after pre- and post-exposure rabies vaccination: A systematic review and dose-response meta-analysis

There are a myriad of vaccine schedules for rabies pre- (PrEP) and post-exposure prophylaxis (PEP) that differ in the number and timedoses, number of visits, length of schedule, and route of administration. The objective of this study was to systematically review the evidence and investigate how thedifferences in schedules influence titres over time. Four databaseswere searched from inception to January 2020 for rabies PrEP and PEP studies. Adose-response meta-analysis was utilised to pool geometric mean titres (GMT) over time. Subgroup analyses by route of administration, age group, and schedule were conducted. 80 studies met the inclusion criteria and contributed with 191 datasets and 12,413 participants. Both intradermal (ID) and intramuscular (IM) PrEP/PEP produce adequate GMTs. Significantly lower GMT levels were achieved in older (>50yrs) compared to younger (<50yrs) participants. Short 1-week schedules were as effective as longer schedules that can take between 3 and 12 weeks to complete. Several effective ID and IM schedules were identified, the selection of a schedule should take into account the patient's needs, costs, availability to return for subsequent doses, and the time required to complete the schedule. Older individuals warrant special attention as they develop lower antibody response
