ABSTRACT

INTRODUCTION: In 2021, a large Midwestern university began selling alcohol to spectators within the football stadium for the first time. The stadium routinely hosts >65,000 spectators, and drinking alcohol is highly prevalent at pre-game tailgating events. Our goal in this study was to determine the impact of in-stadium alcohol sales on the incidence of alcohol-related emergency department (ED) visits and local emergency medical services (EMS) calls. We hypothesized that the availability of alcohol throughout the stadium would lead to an increase in alcohol-related patient presentations.

METHODS: This was a retrospective study including patients who used local EMS and presented to the ED on football Saturdays in the 2019 and 2021 seasons. There were 11 Saturday games with seven home games each year. The 2020 season was excluded due to the impact of COVID-19- related restrictions on attendance. Trained extractors using predefined criteria reviewed records for each patient to determine whether the visit was alcohol related. Using logistic regression analysis we examined the odds of an EMS call and ED visit being alcohol-related before and after the start of stadium alcohol sales. We compared characteristics of visits before and after the onset of stadium alcohol sales using Student’s t-test for continuous variables and chi-square test for categorical variables.

RESULTS: In 2021, after the onset of in-stadium alcohol sales, there were a total of 505 emergency calls to local EMS on football Saturdays (home and away), and 29% of them were for alcohol-related incidents down from 36% of 456 calls in 2019. After adjustment for covariates, the odds of a call being alcohol-related were lower in 2021 than 2019, but this difference was not significant (adjusted odds ratio [aOR] 0.83, 95% CI 0.48-1.42). Looking specifically at the seven home games each season, the difference was more pronounced (31% of calls in 2021 compared to 40% in 2019) but not statistically significant after adjustment for covariates (aOR 0.54, 95% CI 0.15-2.03). In the ED, 1,414 patients were evaluated on game days in 2021 and 8% of them for alcohol-related reasons. This is similar to 2019, when 9% of the 1,538 patients presented due to alcohol-related complaints. After adjustment for covariates, the odds of an ED visit being alcohol-related were similar in 2021 and 2019 (aOR 0.98, 95% CI 0.70-1.38).

CONCLUSION: There was a decrease in alcohol-related EMS calls on home game days in 2021, although the result was not statistically significant. In-stadium alcohol sales had no significant impact on the frequency or proportion of alcohol-related ED visits. The reason for this outcome is unclear, but it is possible that fans drank less at tailgate parties knowing they could consume more once the game started. Long lines and a two-beverage limit at stadium concessions may have kept patrons from consuming excessively. The results of this study may inform similar institutions regarding the safe implementation of alcohol sales during mass-gathering events.

ABSTRACT

INTRODUCTION: Emergency medicine (EM) residency programs have variable approaches to educating residents on recognizing and managing healthcare disparities. We hypothesized that our curriculum with resident-presented lectures would increase residents’ sense of cultural humility and ability to identify vulnerable populations.

METHODS: At a single-site, four-year EM residency program with 16 residents per year, we designed a curriculum intervention from 2019-2021 where all second-year residents selected one healthcare disparity topic and gave a 15-minute presentation overviewing the disparity, describing local resources, and facilitating a group discussion. We conducted a prospective observational study to assess the impact of the curriculum by electronically surveying all current residents before and after the curriculum intervention. We measured attitudes on cultural humility and ability to identify healthcare disparities among a variety of patient characteristics (race, gender, weight, insurance, sexual orientation, language, ability, etc). Statistical comparisons of mean responses were calculated using the Mann-Whitney U test for ordinal data.

RESULTS: A total of 32 residents gave presentations that covered a broad range of vulnerable patient populations including those that identify as Black, migrant farm workers, transgender, and deaf. The overall survey response was 38/64 (59.4%) pre-intervention and 43/64 (67.2%) post-intervention. Improvements were seen in resident self-reported cultural humility as measured by their responsibility to learn (mean responses of 4.73 vs 4.17; P < 0.001) and responsibility to be aware of different cultures (mean responses of 4.89 vs 4.42; P < 0.001). Residents reported an increased awareness that patients are treated differently in the healthcare system based on their race (P < 0.001) and gender (P < 0.001). All other domains queried, although not statistically significant, demonstrated a similar trend.

CONCLUSION: This study demonstrates increased resident willingness to engage in cultural humility and the feasibility of resident near-peer teaching on a breadth of vulnerable patient populations seen in their clinical environment. Future studies may query the impact this curriculum has on resident clinical decision-making.

ABSTRACT

IMPORTANCE: Stroke may be a first manifestation of an occult cancer or may be an indicator of an increased cancer risk in later life. However, data, especially for younger adults, are limited.

OBJECTIVES: To assess the association of stroke with new cancer diagnoses after a first stroke, stratified by stroke subtype, age, and sex, and to compare this association with that in the general population.

DESIGN, SETTING, AND PARTICIPANTS: This registry- and population-based study included 390 398 patients in the Netherlands aged 15 years or older without a history of cancer and with a first-ever ischemic stroke or intracerebral hemorrhage (ICH) between January 1, 1998, and January 1, 2019. Patients and outcomes were identified through linkage of the Dutch Population Register, the Dutch National Hospital Discharge Register, and National Cause of Death Register. Reference data were gathered from the Dutch Cancer Registry. Statistical analysis was performed from January 6, 2021, to January 2, 2022.

EXPOSURE: First-ever ischemic stroke or ICH. Patients were identified by administrative codes from the International Classification of Diseases, Ninth Revision, and the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision.

MAIN OUTCOMES AND MEASURES: The primary outcome was the cumulative incidence of first-ever cancer after index stroke, stratified by stroke subtype, age, and sex, compared with age-, sex- and calendar year-matched peers from the general population.

RESULTS: The study included 27 616 patients aged 15 to 49 years (median age, 44.5 years [IQR, 39.1-47.6 years]; 13 916 women [50.4%]; 22 622 [81.9%] with ischemic stroke) and 362 782 patients aged 50 years or older (median age, 75.8 years [IQR, 66.9-82.9 years]; 181 847 women [50.1%]; 307 739 [84.8%] with ischemic stroke). The cumulative incidence of new cancer at 10 years was 3.7% (95% CI, 3.4%-4.0%) among patients aged 15 to 49 years and 8.5% (95% CI, 8.4%-8.6%) among patients aged 50 years or older. The cumulative incidence of new cancer after any stroke among patients aged 15 to 49 years was higher among women than men (Gray test statistic, 22.2; P < .001), whereas among those aged 50 years or older, the cumulative incidence of new cancer after any stroke was higher among men (Gray test statistic, 943.1; P < .001). In the first year after stroke, compared with peers from the general population, patients aged 15 to 49 years were more likely to receive a diagnosis of a new cancer after ischemic stroke (standardized incidence ratio [SIR], 2.6 [95% CI, 2.2-3.1]) and ICH (SIR, 5.4 [95% CI, 3.8-7.3]). For patients aged 50 years or older, the SIR was 1.2 (95% CI, 1.2-1.2) after ischemic stroke and 1.2 (95% CI, 1.1-1.2) after ICH.

CONCLUSIONS AND RELEVANCE: This study suggests that, compared with the general population, patients aged 15 to 49 years who have had a stroke may have a 3- to 5-fold increased risk of cancer in the first year after stroke, whereas this risk is only slightly elevated for patients aged 50 years or older. Whether this finding has implications for screening remains to be investigated.

ABSTRACT

IMPORTANCE: While epinephrine has been widely used in prehospital resuscitation for pediatric patients with out-of-hospital cardiac arrest (OHCA), the benefit and optimal timing of epinephrine administration have not been fully investigated.

OBJECTIVES: To evaluate the association between epinephrine administration and patient outcomes and to ascertain whether the timing of epinephrine administration was associated with patient outcomes after pediatric OHCA.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study included pediatric patients (<18 years) with OHCA treated by emergency medical services (EMS) from April 2011 to June 2015. Eligible patients were identified from the Resuscitation Outcomes Consortium Epidemiologic Registry, a prospective OHCA registry at 10 sites in the US and Canada. Data analysis was performed from May 2021 to January 2023.

EXPOSURES: The main exposures were prehospital intravenous or intraosseous epinephrine administration and the interval between arrival of an advanced life support (ALS)-capable EMS clinician (ALS arrival) and the first administration of epinephrine.

MAIN OUTCOMES AND MEASURES: The primary outcome was survival to hospital discharge. Patients who received epinephrine at any given minute after ALS arrival were matched with patients who were at risk of receiving epinephrine within the same minute using time-dependent propensity scores calculated from patient demographics, arrest characteristics, and EMS interventions.

RESULTS: Of 1032 eligible individuals (median [IQR] age, 1 [0-10] years), 625 (60.6%) were male. 765 patients (74.1%) received epinephrine and 267 (25.9%) did not. The median (IQR) time interval between ALS arrival and epinephrine administration was 9 (6.2-12.1) minutes. In the propensity score-matched cohort (1432 patients), survival to hospital discharge was higher in the epinephrine group compared with the at-risk group (epinephrine: 45 of 716 [6.3%] vs at-risk: 29 of 716 [4.1%]; risk ratio, 2.09; 95% CI, 1.29-3.40). The timing of epinephrine administration was also not associated with survival to hospital discharge after ALS arrival (P for the interaction between epinephrine administration and time to matching = .34).

CONCLUSIONS AND RELEVANCE: In this study of pediatric patients with OHCA in the US and Canada, epinephrine administration was associated with survival to hospital discharge, while timing of the administration was not associated with survival.

ABSTRACT

BACKGROUND: In Zambia, half of children and adolescents living with HIV (CALWH) on antiretroviral therapy (ART) are virologically unsuppressed. Depressive symptoms are associated with ART non-adherence but have received insufficient attention as mediating factors in the relationship between HIV self-management and household-level adversities. We aimed to quantify theorized pathways from indicators of household adversity to ART adherence, partially mediated by depressive symptoms, among CALWH in two Zambian provinces.

SETTING: In July-September 2017, we enrolled 544 CALWH aged 5-17 years and their adult caregivers into a year-long prospective cohort study.

METHODS: At baseline, CALWH-caregiver dyads completed an interviewer-administered questionnaire, which included validated measures of recent (past 6 months) depressive symptomatology and self-reported past-month ART adherence (never versus sometimes or often missing medication doses). We used structural equation modeling with theta parameterization to identify statistically significant (p<0.05) pathways from household adversities (past-month food insecurity, caregiver self-reported health) to depression (modeled latently), ART adherence, and poor physical health in the past 2 weeks.

RESULTS: Most CALWH (mean age: 11 years, 59% female) exhibited depressive symptomatology (81%). In our structural equation model, food insecurity significantly predicted elevated depressive symptomatology (ß = 0.128), which was associated inversely with daily ART adherence (ß = -0.249) and positively with poor physical health (ß = 0.359). Neither food insecurity nor poor caregiver health were directly associated with ART non-adherence or poor physical health.

CONCLUSIONS: Using structural equation modeling, we found that depressive symptomatology fully mediated the relationship between food insecurity, ART non-adherence, and poor health among CALWH.

ABSTRACT

Persistent pleural effusions (PPEf) represent a known complication of orthotopic liver transplant (OLT). However, their clinical relevance is not well described. We evaluated the clinical, biochemical, and cellular characteristics of post-OLT PPEf and assessed their relationship with longitudinal outcomes. We performed a retrospective cohort study of OLT recipients between 2006 and 2015. Included patients had post-OLT PPEf, defined by effusion persisting >30 days after OLT and available pleural fluid analysis. PPEf were classified as transudates or exudates (Exud^Light) by Light’s criteria. Exudates were subclassified as those with elevated lactate dehydrogenase (Exud^LDH) or elevated protein (Exud^Prot). Cellular composition was classified as neutrophil- or lymphocyte-predominant. Of 1602 OLT patients, 124 (7.7%) had PPEf, of which 90.2% were Exud^Light. Compared to all OLT recipients, PPEf patients had lower two-year survival (HR 1.63; p = 0.002). Among PPEf patients, one-year mortality was associated with pleural fluid RBC count (p = 0.03). While Exud^Light and Exud^Prot showed no association with outcomes, Exud^LDH were associated with increased ventilator dependence (p = 0.03) and postoperative length of stay (p = 0.03). Neutrophil-predominant effusions were associated with increased postoperative ventilator dependence (p = 0.03), vasopressor dependence (p = 0.02), and surgical pleural intervention (p = 0.02). In summary, post-OLT PPEf were associated with increased mortality. Ninety percent of these effusions were exudates by Light’s criteria. Defining exudates using LDH only and incorporating cellular analysis, including neutrophils and RBCs, was useful in predicting morbidity.

ABSTRACT

BACKGROUND: Atrial fibrillation is the most common clinically significant cardiac arrhythmia, and it might lead to heart failure, which prolongs the duration of hospitalization and consequently increases the cost of treatment. Thus, diagnosing and treating atrial fibrillation should be the first line of defense against further complications. This study aimed to determine the incidence rate of postoperative atrial fibrillation and correlation with cardiac surgery on heart valves. A specific aim was to determine the relationship between the prevalence of atrial fibrillation and socio-demographic features.

METHODS: The study has a prospective cross-sectional design. The questionnaire was anonymous, requesting socio-demographic information as inclusion criteria, and the data were analyzed using descriptive statistics methods.

RESULTS: The sample was 201 patients. χ² test and t-test were performed where we found that the frequency of atrial fibrillation was higher in the groups that have had valve surgery compared to other cardiac surgeries (χ² = 7.695, ss = 2, p = 0.021). Atrial fibrillation increased with the age of the patients, but the prevalence of atrial fibrillation was not correlated with body weight.

CONCLUSION: The results of this this study show that atrial fibrillation was higher in the participants who had valve surgery compared to other cardiac surgeries. There was also an increase in atrial fibrillation in the older participants. The results of this study can help to improve nursing practice and the quality of care for cardiac surgery patients with regard to daily activities, or planning nursing care due to the patient’s condition.

ABSTRACT

This study evaluates the range of neurological manifestation in children with COVID-19 (neuro-COVID-19) both with and without the multisystem inflammatory syndrome (MIS-C) and the persistence of symptoms after hospital discharge. The study was conducted as a prospective study of children and adolescents under 18 years of age who were admitted to a children’s hospital for infectious diseases from January 2021 to January 2022. The children had no previous neurological or psychiatric disorders. Out of the 3021 patients evaluated, 232 were confirmed to have COVID-19 and 21 of these patients (9%) showed neurological manifestations associated with the virus. Of these 21 patients, 14 developed MIS-C, and 7 had neurological manifestations unrelated to MIS-C. There was no statistical difference regarding the neurological manifestations during hospitalization and outcomes between patients with neuro-COVID-19 who had or did not have MIS-C, except for seizures that occurred more frequently in patients with neuro-COVID-19 without MIS-C (p-value = 0.0263). One patient died, and 5 patients still had neurological or psychiatric manifestations at discharge, which persisted for up to 7 months. The study highlights that SARS-CoV-2 infection can affect the central and peripheral nervous system, particularly in children and adolescents with MIS-C, and that it is crucial to be vigilant for long-term adverse outcomes, as the neurological and psychiatric effects of COVID-19 in children are emerging during an important stage of brain development.

ABSTRACT

AIM: To compare safety and functional outcomes of intravenous thrombolysis (IVT) between females and males with acute ischaemic stroke (AIS) in relation to preadmission use of antiplatelets.

METHODS: Multicentre cohort study of patients admitted from 1 January 2014 to 31 January 2020 to hospitals participating in the Swiss Stroke Registry, presenting with AIS and receiving IVT. Primary safety outcome was in-hospital symptomatic intracerebral haemorrhage (sICH). Primary functional outcome was functional independence at 3 months after discharge. Multivariable logistic regression models were fitted to assess the association between sex and each outcome according to preadmission use of antiplatelets.

RESULTS: The study included 4996 patients (42.51 % females, older than males, median age 79 vs 71 years, p < 0.0001). Comparable proportions of females (39.92 %) and males (40.39 %) used antiplatelets before admission (p = 0.74). In total, 3.06 % females and 2.47 % males developed in-hospital sICH (p = 0.19), with similar odds (adjusted odds ratio, [AOR] 0.93, 95 % confidence interval, [CI] 0.63-1.39). No interaction was found between sex and preadmission use of either single or dual antiplatelets in relation to in-hospital sICH (p = 0.94 and p = 0.23). Males had higher odds of functional independence at 3 months (AOR 1.34, 95 % CI 1.09-1.65), regardless of preadmission use of antiplatelets (interaction between sex and preadmission use of either single or dual antiplatelets p = 0.41 and p = 0.58).

CONCLUSION: No sex differences were observed in the safety of IVT regarding preadmission use of antiplatelets. Males showed more favourable 3-month functional independence than females; however, this sex difference was apparently not explained by a sex-specific mechanism related to preadmission use of antiplatelets.

ABSTRACT

This invited Team Profile was created by the Tiwary group, University of Maryland, College Park (USA) and the Seeliger group, Stony Brook University, New York (USA). They recently published an article on the previously made observation through in-cell screening that the blockbuster cancer drug Gleevec has the same binding affinity, yet different dissociation kinetics against wild-type and N368S-mutated Abl kinase. Through all-atom enhanced molecular dynamics simulations guided by statistical mechanics and information theory, they were able to explain the mechanistic basis of this perplexing observation. Their work has ramifications for how pharmaceutical drugs might experience kinetic resistance due to mutations. “Protein Flexibility and Dissociation Pathway Differentiation Can Explain Onset of Resistance Mutations in Kinases”, M.
