Delays in Hepatitis A vaccination in people with HIV in Houston, Texas between 2010 and 2018.

Background: Studies have demonstrated low hepatitis A virus (HAV) vaccination rates among persons with HIV (PWH). Methods: We conducted a retrospective study of persons entering HIV care at two clinics in Houston, Texas between 2010 and 2018. We defined those eligible for HAV vaccination as those who had no history of HAV vaccination and had a negative anti-HAV IgG at entry to care. Kaplan-Meier curves summarized time to receipt of HAV vaccines. The proportions of patients who received 1 and 2 HAV vaccines at 6, 12, and 24 months were estimated. Cox proportional hazards regression evaluated associations between patient characteristics and vaccination. Significant factors were included in a multivariable Cox proportional hazards model. Results: Of 6,515 patients, 1372 were eligible for HAV vaccination. Of eligible patients, 29.2 % received 1 HAV vaccination at 6 months, 37.1 % at 12 months, and 47.8 % at 24 months. At 6 months, 10 % received 2 HAV vaccinations, 21.1 % at 12 months, and 33.4 % at 24 months. In multivariable analysis, men who have sex with men (adjusted HR 1.35, 95 % CI 1.06, 1.73) or those who had CD4 count ≥ 200 cells/µl (adjusted HR 2.52, 95 % CI 1.89, 3.37) had their second vaccination sooner than those who were not men who have sex with men or who had CD4 counts < 200 cells/µl, respectively. Patients > 50 years of age had their second vaccination sooner than those aged 30-50 years (adjusted HR 1.47, 95 % CI 1.08, 1.99). Those with active substance history had a longer time to second vaccination compared to those with no substance use history (adjusted HR 0.57, 95 % CI 0.40, 0.82). Conclusions: HAV vaccination rates were low and highlight the need for effective solutions to address HAV immunization gaps in PWH, especially among young patients, those with active substance use disorders, and those with significant immunocompromise.

Opioid Overdose Recognition: A Survey of Perceived Preparedness and Desire for Curricular Integration Among Current US Medical Students.

OBJECTIVES: Opioid overdose deaths remain a major health issue in the United States (US). As future physicians, medical students must receive comprehensive training to recognize and manage opioid overdoses. This study aimed to highlight training gaps at the medical student level and understand students' attitudes toward patients with opioid use disorder (OUD). METHODS: We assessed baseline knowledge of and attitudes toward the management of opioid overdoses and naloxone administration among medical students in the US. Two validated survey tools (Opioid Overdose Knowledge Scale and Opioid Overdose Attitude Scale) were administered to medical students training at accredited institutions along with supplemental questions measuring knowledge and attitudes towards opioid overdose management, naloxone administration, and prior training. RESULTS: The final sample had N = 73 participants from US medical schools with a mean age of 25.3 (range of 22-37): 72.6% of respondents were female. Although most respondents reported personal/professional experience with OUD before medical school, they expressed interest in additional training. Knowledge surrounding opioid overdoses increased insignificantly over the 4 years of medical school. However, there was a significant increase in both perceived competence in overdose recognition/management and in concerns about intervening from the first to fourth year of medical school. Female respondents had significantly lower perceived competence and readiness to intervene sub-scores than male counterparts; however, there was no significant difference in overall attitude and knowledge scores when stratified by sex. Incorporating opioid overdose prevention training (OOPT) into early medical education was favorable among respondents, who expressed an overwhelming interest in learning and supporting patients with OUD. CONCLUSIONS: Given the ongoing opioid crisis, medical students are ideally placed to identify and manage opioid overdoses. Medical students are ready to receive this training, thus strengthening the argument for OOPT integration into early medical student curricula.

Delays in Hepatitis B Immunization Series Completion in People With Human Immunodeficiency Virus.

Background: Studies have demonstrated low hepatitis B virus (HBV) vaccine series completion among persons with human immunodeficiency virus (HIV). Methods: We conducted a retrospective record review of persons entering HIV care at 2 clinics in Houston, Texas, between 2010 and 2018. Kaplan-Meier curves summarized time to receipt of HBV vaccines for those eligible for vaccination. We estimated the proportions of patients who had received 1, 2, or 3 HBV vaccine doses at 12 and 24 months after entry to care. A Prentice Williams and Peterson total time model was used to evaluate associations between patient characteristics and time to vaccination. Results: Of the 5357 patients who entered care, 2718 were eligible for HBV vaccination. After 2 years of follow-up, 51.2% of those eligible had received 1 HBV vaccine, 43.2% had received 2, and 28.4% received 3 vaccines. With adjustment for significant cofactors, patients whose CD4 cell count was ≥200/µL (adjusted hazard ratio [aHR], 1.43 [95% confidence interval (CI), 1.29-1.59]) and transgender patients (1.49 [1.08-2.04]) received any given vaccine dose sooner than those with CD4 cell counts <200/µL or cisgender patients, respectively. Compared with non-Hispanic whites, Hispanic patients were vaccinated sooner (aHR, 1.28 [95% CI, 1.07-1.53]). Those with an active substance use history had a significantly longer time to vaccination than those with no substance use history (aHR, 0.73 [95% CI, .62-.85]). Conclusions: Strategies are needed to increase HBV vaccine completion rates in our study population, particularly among those with CD4 cell counts <200/µL or with a substance use disorder.

Lipid emulsion therapy during management of the critically-ill poisoned patient: a prospective cohort study.

BACKGROUND: Despite conflicting data, intravenous lipid emulsion has emerged as a potential antidote. The "lipid sink" theory suggests that following intravenous administration of lipid, lipophilic drugs are sequestered in the vascular compartment, thereby reducing their tissue concentrations. This study sought to determine if survival is associated with the intoxicant's degree of lipophilicity. METHODS: We reviewed all cases in the Toxicology Investigators Consortium's lipid sub-registry between May 2012 through December 2018. Information collected included demographics, exposure circumstances, clinical course, management, disposition, and outcome. The primary outcome was survival after lipid emulsion therapy. Survival was stratified by the log of the intoxicant's octanol-water partition coefficient. We also assessed the association between intoxicant lipophilicity and an increase in systolic blood pressure after lipid emulsion administration. RESULTS: We identified 134 patients, including 81 (60.4%) females. The median age was 40 years (interquartile range 21-75). One hundred and eight (80.6%) patients survived, including 45 (33.6%) with cardiac arrest during their intoxication. Eighty-two (61.2%) were hypotensive, and 98 (73.1%) received mechanical ventilation. There was no relationship between survival and the log of the partition coefficient of the intoxicant on linear analysis (P = 0.89) or polynomial model (P = 0.10). Systolic blood pressure increased in both groups. The median (interquartile range) systolic blood pressure before lipid administration was 68 (60-78) mmHg for those intoxicants with a log partition coefficient < 3.6 compared with 89 (76-104) mmHg after lipid administration. Among those drugs with a log partition coefficient > 3.6, the median (interquartile range) was 69 (60-84) mmHg before lipid and 89 (80-96) mmHg after lipid administration. CONCLUSION: Most patients in this cohort survived. Lipophilicity was not correlated with survival or the observed changes in blood pressure. The study did not address the efficacy of lipid emulsion.

Impact of Faculty Incentivization on Resident Evaluations.

INTRODUCTION: In the Program Requirements for Graduate Medical Education in Emergency Medicine, the Accreditation Council for Graduate Medical Education requires frequent and routine feedback. It is a common challenge for program leadership to obtain adequate and effective summative evaluations. METHODS: This is a retrospective, case-crossover, interventional study conducted in an academic medical center. This study occurred over a two-year period, with an intervention between years one and two. Throughout year two of the study, faculty incentive compensation was linked to completion of end-of-shift evaluations. We compared pre- an post-implementation data using paired sample t-tests with the significance level P < .05 applied. RESULTS: After implementation of the incentive metric there was an increase in the number of total evaluations by 42% (P = .001). The mean number of evaluations submitted by each faculty per shift increased from 0.45 to 0.86 (SD 0.56, P < .001). Overall, 32 of the 38 faculty members (84.2%) had an increase in the number of evaluations submitted per shift during the intervention period with an average increase of 0.5 evaluations per shift (range 0.01-1.54). CONCLUSION: Incentivizing faculty to submit resident evaluations through use of bonus compensation increased the number of evaluations at our institution. This information may be applied by other programs to increase resident evaluations.

Severe outcomes following pediatric cannabis intoxication: a prospective cohort study of an international toxicology surveillance registry.

INTRODUCTION: An increasing number of jurisdictions have legalized recreational cannabis for adult use. The subsequent availability and marketing of recreational cannabis has led to a parallel increase in rates and severity of pediatric cannabis intoxications. We explored predictors of severe outcomes in pediatric patients who presented to the emergency department with cannabis intoxication. METHODS: In this prospective cohort study, we collected data on all pediatric patients (<18 years) who presented with cannabis intoxication from August 2017 through June 2020 to participating sites in the Toxicology Investigators Consortium. In cases that involved polysubstance exposure, patients were included if cannabis was a significant contributing agent. The primary outcome was a composite severe outcome endpoint, defined as an intensive care unit admission or in-hospital death. Covariates included relevant sociodemographic and exposure characteristics. RESULTS: One hundred and thirty-eight pediatric patients (54% males, median age 14.0 years, interquartile range 3.7-16.0) presented to a participating emergency department with cannabis intoxication. Fifty-two patients (38%) were admitted to an intensive care unit, including one patient who died. In the multivariable logistic regression analysis, polysubstance ingestion (adjusted odds ratio = 16.3; 95% confidence interval: 4.6-58.3; P < 0.001)) and cannabis edibles ingestion (adjusted odds ratio = 5.5; 95% confidence interval: 1.9-15.9; P = 0.001) were strong independent predictors of severe outcome. In an age-stratified regression analysis, in children older than >10 years, only polysubstance abuse remained an independent predictor for the severe outcome (adjusted odds ratio 37.1; 95% confidence interval: 6.2-221.2; P < 0.001). As all children 10 years and younger ingested edibles, a dedicated multivariable analysis could not be performed (unadjusted odds ratio 3.3; 95% confidence interval: 1.6-6.7). CONCLUSIONS: Severe outcomes occurred for different reasons and were largely associated with the patient's age. Young children, all of whom were exposed to edibles, were at higher risk of severe outcomes. Teenagers with severe outcomes were frequently involved in polysubstance exposure, while psychosocial factors may have played a role.

Beyond diversity and inclusion: Developing a research agenda for anti-racism in emergency medicine education.

Background: Addressing racism in emergency medicine education is vital for providing optimal training and assessment of physicians in the specialty, developing physicians with the skills necessary to advocate for their patients, and recruiting and retaining a diverse group of physicians. To form a prioritized research agenda, the Society of Academic Emergency Medicine (SAEM) conducted a consensus conference at the annual meeting in May 2022 on addressing racism in emergency medicine, which included a subgroup on education. Methods: The education workgroup worked on summarizing the current literature on addressing racism in emergency medicine education, identifying critical knowledge gaps, and creating a consensus-driven research agenda for addressing racism in emergency medicine education. We used a nominal group technique and modified Delphi to develop priority questions for research. We then distributed a pre-conference survey to conference registrants to rate priority areas for research. During the consensus conference, group leaders provided an overview and background describing the rationale for the preliminary research question list. Attendees were then involved in discussions to help modify and develop research questions. Results: Nineteen questions were initially selected by the education workgroup as potential areas for research. The education workgroup's next round of consensus building resulted in a consensus of ten questions to be included in the pre-conference survey. No questions in the pre-conference survey reached consensus. After robust discussion and voting by workgroup members and attendees at the consensus conference, six questions were determined to be priority research areas. Conclusions: We believe recognizing and addressing racism in emergency medicine education is imperative. Critical gaps in curriculum design, assessment, bias training, allyship, and the learning environment negatively impact training programs. These gaps must be prioritized for research as they can have adverse effects on recruitment, the ability to promote a safe learning environment, patient care, and patient outcomes.

Effect of the Cyberattack Targeting the Irish Health System in May 2021 on Radiation Treatment at St. Luke's Radiation Oncology Network.

On May 14, 2021, the Health Service Executive (HSE) of Ireland experienced a major ransomware cyberattack. The HSE initially took down all of its information technology systems to protect its core systems. All Internet connections within the HSE were unavailable from 7 am for approximetely three weeks which had a major effect on the radiation oncology service nationally within the public service. St. Luke's Radiation Oncology Network (SLRON) is a complex, 3-center radiation oncology service, and it is the largest in the country; with 14 linear accelerators, it is one of the largest radiation centers in Europe. This article details the response of SLRON to the outage resultant from the cyberattack. Although the outage affected all patient services, including laboratory, diagnostic imaging, and inpatient care, the article primarily focuses on our response to get the radiation oncology service restarted as quickly as possible and details the steps we took to reinstate our systems safely, how we prioritized patient treatments, and how we communicated with patients, staff, and the public without having access to standard communication pathways. All decisions were risk assessed and were made with the best resources available to us at the time to maximize the outcome for our patients and mitigate significant delays. The risk remains ongoing, and the onerous task of uploading backlogs and reconciling patient records is a continuing risk.

Predictors of severe outcome following opioid intoxication in children.

INTRODUCTION: While the opioid crisis has claimed the lives of nearly 500,000 in the U.S. over the past two decades, and pediatric cases of opioid intoxications are increasing, only sparse data exist regarding risk factors for severe outcome in children following an opioid intoxication. We explore predictors of severe outcome (i.e., intensive care unit [ICU] admission or in-hospital death) in children who presented to the Emergency Department with an opioid intoxication. METHODS: In this prospective cohort study we collected data on all children (0-18 years) who presented with an opioid intoxication to the 50 medical centers in the US and two international centers affiliated with the Toxicology Investigators Consortium (ToxIC) of the American College of Medical Toxicology, from August 2017 through June 2020, and who received a bedside consultation by a medical toxicologist. We collected relevant demographic, clinical, management, disposition, and outcome data, and we conducted a multivariable logistic regression analysis to explore predictors of severe outcome. The primary outcome was a composite severe outcome endpoint, defined as ICU admission or in-hospital death. Covariates included sociodemographic, exposure and clinical characteristics. RESULTS: Of the 165 (87 females, 52.7%) children with an opioid intoxication, 89 (53.9%) were admitted to ICU or died during hospitalization, and 76 did not meet these criteria. Seventy-four (44.8%) children were exposed to opioids prescribed to family members. Fentanyl exposure (adjusted OR [aOR] = 3.6, 95% CI: 1.0-11.6; p = 0.03) and age ≥10 years (aOR = 2.5, 95% CI: 1.2-4.8; p = 0.01) were independent predictors of severe outcome. CONCLUSIONS: Children with an opioid toxicity that have been exposed to fentanyl and those aged ≥10 years had 3.6 and 2.5 higher odds of ICU admission or death, respectively, than those without these characteristics. Prevention efforts should target these risk factors to mitigate poor outcomes in children with an opioid intoxication.

Sex Differences in Substance Use and Misuse: A Toxicology Investigators' Consortium (ToxIC) Registry Analysis.

BACKGROUND: Variations between male and female populations are previously reported in classes of harmfully used/misused drugs, severity of substance use disorder and risk of relapse. The aim of this study was to provide a review of bedside medical toxicologist managed, sex-specific poisonings in adults that present with harmful drug use/misuse. METHODS: ToxIC Registry cases ≥19 and ≤65 years old, with harmful drug use or misuse during the timeframe June 2010-December 2016, were studied. Demographics, primary agents of toxic exposure, administration route and complications were analyzed. Descriptive methods were used in the analysis. RESULTS: The database included 51,440 cases. Of these, 3426 cases were analyzed in which the primary reason for the encounter was harmful substance use/misuse. Females were found to harmfully use/misuse pharmaceutical drugs (N=806, 65.6%) more than nonpharmaceutical drugs (N=423, 34.4%). Males more frequently used nonpharmaceutical drugs (N=1189, 54.1%) than pharmaceutical drugs (1008, 45.9%). Analgesics were used by females (N= 215, 18.2%) and males (N=137, 6.6%). Sedative hypnotics were used by females (N=165, 14%) and males (N=160, 7.8%). Psychoactive agents were used by males (N=325, 15.8%) and females (N=67, 5.7%). Sympathomimetics were used by males (N=381, 18.5%) and females (N=151, 12.8%). The majority of both male and female participants, 1712 (57.9%), utilized an oral route of administration. However, 312 (16.5%) of males utilized inhalation vs 73 (6.8%) of females inhaled their substance. CONCLUSION: There were sex-specific differences among patients evaluated for harmful substance use/misuse by toxicologists. Considering these differences in regards to management and preventive approaches may be indicated.

Sex Differences in Pediatric Poisonings by Age Group: a Toxicology Investigators' Consortium (ToxIC) Analysis (2010-2016).

OBJECTIVE: To review pediatric poisonings evaluated at the bedside by medical toxicologists and reported in the ToxIC registry, by sex and age group. METHODS: Pediatric poisoning cases age ≤18 years, reported between January 2010 and December 2016, were reviewed. Descriptive statistics were used to describe study variables by age group and sex. RESULTS: A total of 12,699 cases were analyzed. There were 7517 females and 5182 males. Those < 2 years old represented 12.5% of the study group (n = 1584), 17.2% were 2-6 years old (n = 2178), 8.6% were 7-12 years old (n = 1097), and 61.7% were 13-18 years old (n = 7840). The most common primary reasons for encounter were intentional pharmaceutical with 4900 females and 1836 males; intentional non-pharmaceutical with 952 females and 1213 males; unintentional pharmaceutical with 539 females and 644 males; and unintentional non-pharmaceutical with 435 females and 593 males. Overall, pharmaceuticals were the most commonly involved agents, including analgesics (20.9% of cases) and antidepressants (11% of cases): 27.8% of females and 10.7% of males were reportedly exposed to an analgesic.13.7% of females and 7.0% of males were reportedly exposed to an antidepressant. Among 1584 cases under 2 years, there were 747 females and 837 males; among 2178 cases aged 2-6 years, there were 954 females and 1224 males; among 1097 cases aged 7-12 years, there were 555 females and 542 males; and among 7840 cases aged 13-18 years, there were 5261 females and 2579 males. Death was reported in 0.7% of the cases: 20 females and 18 males. 6.1% of cases were managed with intubation: 421 females and 351 males. CONCLUSIONS: Sex-based characteristics of poisonings varied by age group among pediatric poisoning presentations reported to the ToxIC registry and further research is needed to determine implications for education and prevention efforts.

Sex differences in patients with suicidal intent that are managed by toxicologists: An analysis of the Toxicology Investigators' Consortium (ToxIC) Registry.

INTRODUCTION: The Toxicology Investigator's Consortium (ToxIC) maintains a prospective case registry of all patients that have been managed at the bedside by medical toxicologists. We set out to characterize the differences in toxicological suicide attempts between men and women among adult patients with poisonings managed by medical toxicologists. METHODS: ToxIC database consults for adults aged 19-65 whose primary reasons for encounter were classified as suicide attempt were used for this study (1/2010-12/2016). Data used for analysis included primary agents of toxic exposure, routes of administration, and complications. The statistical analysis was limited to descriptive methods. RESULTS: Out of 51,440 registry cases, 33,259 cases remained for analysis after applying the ages 19-65 and removing those without complete data. Of these, there were 4827 suicide attempts (14.5% of toxicological exposures) which were sub classified by gender. There were more females (F) than males (M) whose toxicology consults were due to suicidal attempts (57.6% versus 42.4%). We also found that more males used alcohol as their primary agent (2.8%M v 1.5%F) or a nonpharmaceutical (%7.4 M v %2.3 F). CONCLUSIONS: In our study, we found that there were more females than males who attempted suicide by self-poisoning; and more of them used pharmaceuticals than males. In contrast, a greater number of males used nonpharmaceuticals such as alcohol. We did not find large sex-differences in suicide completion rates, routes of administration, or subsequent symptomologies. In summary, sex-based differences were observed between adult patients with suicidal-intent exposures/ingestions managed at the bedside by medical toxicologists.

Interest in and barriers to participation in a Facebook-delivered weight loss program among female cancer survivors with overweight or obesity.

BACKGROUND: Although excess body weight is linked to post-treatment complications for cancer survivors, obesity rates have increased rapidly among adult cancer survivors. Innovative approaches to weight loss programs, such as via social media, are needed to engage female cancer survivors. The purpose of this study is to explore important components of a Facebook-delivered weight loss program for female cancer survivors. METHODS: Female cancer survivors who are overweight or obese and finished active treatment completed a web-based, mixed-methods survey. RESULTS: Participants (N=96) were on average 54.3±9.6 years old, 89% white, 66% obese, and 87% tried to lose weight in the last year. Health concerns were the most important reason (88%) for wanting to lose weight. Barriers to weight loss included other health issues (52%) and perceived sacrifice/burden of weight loss process (35%). Qualitative themes for barriers included inability to make dietary changes (19%), lack of motivation (18%), and physical limitations (13%). Participants were most interested in a weight loss program delivered via Facebook (81%), led by a weight loss counselor (78%), provided healthy recipes (73%) and exercise videos (72%). Qualitative themes included information on cancer treatment effects (25%), calorie tracker (21%), and exercise modifications (17%). Qualitatively, concerns about weight loss included fear of cancer recurrence (20%) and lack of confidence in weight loss efforts (17%). CONCLUSIONS: While female cancer survivors are interested in a Facebook-delivered weight loss program, additional research needs to address customization and delivery to address specific barriers experienced by cancer survivors.

Sex Differences in Poisonings Among Older Adults: An Analysis of the Toxicology Investigators Consortium (ToxIC) Registry, 2010 to 2016.

PURPOSE: Adults aged >65 years are susceptible to intentional and unintentional poisoning, with contributing factors that include polypharmacy, comorbidity, susceptibility to medication error, and gaps in research. Although toxicologists are often tasked with managing and preventing poisoning among older adults, little is known about sex differences in these poisonings. The aim of this study was to review sex differences in poisonings among older adults managed at the bedside by medical toxicologists. METHODS: All case subjects aged >65 years in the Toxicology Investigators Consortium (ToxIC) registry between January 2010 and December 2016 were reviewed. Data included reasons for exposure and consultation, exposure agents and routes, presenting clinical findings, and treatment provided. Cases missing age, sex, or primary reason for toxicology consultation data were excluded. We used χ2 tests to assess differences in distribution of study variables according to participant sex. FINDINGS: Among 51,441 total registry cases, 542 (1.05%) were excluded because of missing data. Among the remaining 50,899 cases, 2930 (5.8%) were included for age >65 years; 52.3% of older adults were female. Race was missing or unknown for 49.2% of cases. Adverse drug reactions were more commonly encountered in female subjects than in their male counterparts (9.6% vs 6.4%; P = 0.001). No statistically significant sex differences were observed for total numbers of intentional, unintentional pharmaceutical, and nonpharmaceutical exposures. The most common medications involved were cardiovascular (16.8%) and analgesics/opioids (14.8%). Female subjects were more likely than male subjects to be evaluated by a toxicologist for cardiovascular medications (18.7% vs 14.7%; P = 0.004) and analgesics/opioids (17.6% vs 11.8%; P < 0.001). Male subjects were more likely than female subjects to be evaluated for ethanol toxicity (7.4% vs 1%; P < 0.001) and for envenomations (4.2% vs 1.8%; P < 0.001). The most common route of exposure was oral ingestion (81.3%). Signs/symptoms were noted in 54.8% of cases, with the most common abnormal vital sign being bradycardia (17.2%). Pharmacologic support was the most common intervention and was more common in male subjects than in female subjects (17.7% vs 12.3%; P < 0.001). Deaths were reported in 38 female subjects (2.45%) and 46 male subjects (3.34%); there was no statistically significant difference in death rate according to sex (P = 0.148). IMPLICATIONS: Older female adults were more commonly evaluated by a medical toxicologist for an adverse drug reaction than older male adults. Female patients were more likely than male patients to be evaluated for poisoning related to analgesic/opioids and cardiovascular medications, and older male patients more frequently received pharmacologic support than older female patients. No significant sex differences were observed in numbers of toxicology consultations for intentional, unintentional pharmaceutical, and nonpharmaceutical exposures.

mHealth for the Detection and Intervention in Adolescent and Young Adult Substance Use Disorder.

PURPOSE OF REVIEW: The goal of this review is to highlight recent research in mHealth based approaches to the detection and treatment of substance use disorders in adolescents and young adults. RECENT FINDINGS: The main methods for mHealth based detection include mobile phone based self-report tools, GPS tracking, and wearable sensors. Wearables can be used to detect physiologic changes (e.g., heart rate, electrodermal activity) or biochemical contents of analytes (i.e. alcohol in sweat) with reasonable accuracy, but larger studies are needed. Detection methods have been combined with interventions based on mindfulness, education, incentives/goals and motivation. Few studies have focused specifically on the young adult population, although those that did indicate high rates of utilization and acceptance. SUMMARY: Research that explores the pairing of advanced detection methods such as wearables with real time intervention strategies is crucial to realizing the full potential of mHealth in this population.

SoMe and Self Harm: The use of social media in depressed and suicidal youth.

Increased access and use of social media on smartphones and tablets have changed interpersonal communication styles. Because of the ease of social media access and the ability to reach a large number of individuals, social media is an ever more important modality that connects individuals. Importantly, adolescents have adopted social media platforms to discuss issues related to mental health. There is little existing data regarding how adolescents who are depressed or suicidal use social media prior to treatment in the emergency department (ED) for medical care of their psychiatric illness. In this paper, we present formative evidence of social media behaviors in 29 adolescents seeking emergency care for depression or suicidal ideation. Participants were surveyed regarding social media use and motivations to post content regarding depression, death or dying. Among the participants who allowed the research team to view their social media accounts, 40% (n=6) posted content related to depression, death or dying, while 20% (n=3) wrote that they felt depressed and 13.3% (n=2) posted that they wanted to die. Qualitative discussions with participants provided description of reasons for posting content on social media about depression, death and dying, or reasons that individuals refrained from posting online. Despite methodological and technical challenges in research, social media may prove be valuable in detection and intervention of adolescents who are depressed and contemplating suicide.

Methods for Evaluating the Content, Usability, and Efficacy of Commercial Mobile Health Apps.

Commercial mobile apps for health behavior change are flourishing in the marketplace, but little evidence exists to support their use. This paper summarizes methods for evaluating the content, usability, and efficacy of commercially available health apps. Content analyses can be used to compare app features with clinical guidelines, evidence-based protocols, and behavior change techniques. Usability testing can establish how well an app functions and serves its intended purpose for a target population. Observational studies can explore the association between use and clinical and behavioral outcomes. Finally, efficacy testing can establish whether a commercial app impacts an outcome of interest via a variety of study designs, including randomized trials, multiphase optimization studies, and N-of-1 studies. Evidence in all these forms would increase adoption of commercial apps in clinical practice, inform the development of the next generation of apps, and ultimately increase the impact of commercial apps.

Integrating Personalized Technology in Toxicology: Sensors, Smart Glass, and Social Media Applications in Toxicology Research.

Rapid proliferation of mobile technologies in social and healthcare spaces create an opportunity for advancement in research and clinical practice. The application of mobile, personalized technology in healthcare, referred to as mHealth, has not yet become routine in toxicology. However, key features of our practice environment, such as frequent need for remote evaluation, unreliable historical data from patients, and sensitive subject matter, make mHealth tools appealing solutions in comparison to traditional methods that collect retrospective or indirect data. This manuscript describes the features, uses, and costs associated with several of common sectors of mHealth research including wearable biosensors, ingestible biosensors, head-mounted devices, and social media applications. The benefits and novel challenges associated with the study and use of these applications are then discussed. Finally, opportunities for further research and integration are explored with a particular focus on toxicology-based applications.
