Sexist, Racist, and Homophobic Violence against Paramedics in a Single Canadian Site.

Violence against paramedics is widely recognized as a serious, but underreported, problem. While injurious physical attacks on paramedics are generally reported, non-physical violence is less likely to be documented. Verbal abuse can be very distressing, particularly if the harassment targets personal or cultural identities, such as race, ethnicity, gender, or sexual orientation. Leveraging a novel, point-of-event reporting process, our objective was to estimate the prevalence of harassment on identity grounds against paramedics in a single paramedic service in Ontario, Canada, and assess its potentially differential impact on emotional distress. In an analysis of 502 reports filed between 1 February 2021 and 28 February 2022, two paramedic supervisors independently coded the free-text narrative descriptions of violent encounters for themes suggestive of sexism, racism, and homophobia. We achieved high inter-rater agreement across the dimensions (k = 0.73-0.83), and after resolving discrepant cases, we found that one in four violent reports documented abuse on at least one of the identity grounds. In these cases, paramedics were 60% more likely to indicate being emotionally distressed than for other forms of violence. Our findings offer unique insight into the type of vitriol paramedics experience over the course of their work and its potential for psychological harm.

Integrating biobehavioral information to predict mood disorder suicide risk.

The will to live and the ability to maintain one's well-being are crucial for survival. Yet, almost a million people die by suicide globally each year (Aleman and Denys, 2014), making premature deaths due to suicide a significant public health problem (Saxena et al., 2013). The expression of suicidal behaviors is a complex phenotype with documented biological, psychological, clinical, and sociocultural risk factors (Turecki et al., 2019). From a brain disease perspective, suicide is associated with neuroanatomical, neurophysiological, and neurochemical dysregulations of brain networks involved in integrating and contextualizing cognitive and emotional regulatory behaviors. From a symptom perspective, diagnostic measures of dysregulated mood states like major depressive symptoms are associated with over sixty percent of suicide deaths worldwide (Saxena et al., 2013). This paper reviews the neurobiological and clinical phenotypic correlates for mood dysregulations and suicidal phenotypes. We further propose machine learning approaches to integrate neurobiological measures with dysregulated mood symptoms to elucidate the role of inflammatory processes as neurobiological risk factors for suicide.

Reduced sensorimotor beta dynamics could represent a "slowed movement state" in healthy individuals.

It is well established that the amplitude of beta oscillations (∼13-30 Hz)-recorded over the sensorimotor cortex-distinctly change throughout movement. Specifically, a movement-related beta decrease (MRBD) occurs before and during movement, and a post-movement beta rebound (PMBR) follows. We investigated how the magnitude of the MRBD and PMBR vary when participants are put in an experimentally induced slow versus fast movement state. Individuals performed a task with blocks that elicited longer reaction times (RTs) and shorter RTs (SLOW and FAST blocks, respectively) while scalp-electroencephalography (EEG) was recorded. The timing of an upcoming movement was also modulated to create blocks with certain and uncertain response timing (FIXED and VARIED blocks, respectively). We found that beta modulation was reduced in SLOW blocks compared to FAST blocks (i.e., a less negative MRBD and less positive PMBR). For the movement certainty manipulation, we saw mixed behavioral and EEG results. Our primary finding of reduced beta modulation during an experimentally induced "slowed movement state" aligns with previous work showing reduced movement-related beta activity in patients with Parkinson's disease.

Protected 911: Development, Implementation, and Evaluation of a Prehospital COVID-19 High-Risk Response Team.

Patients with COVID-19 who require aerosol-generating medical procedures (such as endotracheal intubation) are challenging for paramedic services. Although potentially lifesaving for patients, aerosolizing procedures carry an increased risk of infection for paramedics, owing to the resource limitations and complexities of the pre-hospital setting. In this paper, we describe the development, implementation, and evaluation of a novel pre-hospital COVID-19 High-Risk Response Team (HRRT) in Peel Region in Ontario, Canada. The mandate of the HRRT was to attend calls for patients likely to require aerosolizing procedures, with the twofold goal of mitigating against COVID-19 infections in the service while continuing to provide skilled resuscitative care to patients. Modelled after in-hospital 'protected code blue' teams, operationalizing the HRRT required several significant changes to standard paramedic practice, including the use of a three-person crew configuration, dedicated safety officer, call-response checklists, multiple redundant safety procedures, and enhanced personal protective equipment. Less than three weeks after the mandate was given, the HRRT was operational for a 12-week period during the first wave of COVID-19 in Ontario. HRRT members attended ~70% of calls requiring high risk procedures and were associated with improved quality of care indicators. No paramedics in the service contracted COVID-19 during the program.

Preoperative opioid, sedative, and antidepressant use is associated with increased postoperative hospital costs in colorectal surgery.

BACKGROUND: Opioid (OPD), sedative (SDT), and antidepressant (ADM) prescribing has increased dramatically over the last 20 years. This study evaluated preoperative OPD, SDT, and ADM use on hospital costs in patients undergoing colorectal resection at a single institution. METHODS: This study was a retrospective record review. The local ACS-NSQIP database was queried for adult patients (age ≥ 18 years) undergoing open/laparoscopic, partial/total colectomy, or proctectomy from January 1, 2013 to December 31, 2016. Individual patient medical records were reviewed to determine preoperative OPD, SDT, and AD use. Hospital cost data from index admission were captured by the hospital cost accounting system and matched to NSQIP query-identified cases. All ACS-NSQIP categorical patient characteristic, operative risk, and outcome variables were compared in medication groups using chi-square tests or Fisher's exact tests, and continuous variables were compared using Mann-Whitney U tests. RESULTS: A total of 1185 colorectal procedures were performed by 30 different surgeons. Of these, 27.6% patients took OPD, 18.5% SDT, and 27.8% ADM preoperatively. Patients taking OPD, SDT, and ADM were found to have increased mean total hospital costs (MTHC) compared to non-users (30.8 vs 23.6 for OPD, 31.6 vs 24.4 for SDT, and 30.7 vs 23.8 for ADM). OPD and SDT use were identified as independent risk factors for increased MTHC on multivariable analysis. CONCLUSION: Preoperative OPD and SDT use can be used to predict increased MTHC in patients undergoing colorectal resections.

A Retrospective Review: Patient-Reported Preoperative Prescription Opioid, Sedative, or Antidepressant Use Is Associated with Worse Outcomes in Colorectal Surgery.

BACKGROUND: Prescription opioid, sedative, and antidepressant use has been on the rise. The effect of these medications on outcomes in colorectal surgery has not been established. OBJECTIVE: This study aimed to evaluate the impact of preoperative prescription opioid, sedative, and antidepressant use on postoperative outcomes following colorectal surgery. DESIGN: This study was a retrospective database and medical record review. SETTINGS: This study was conducted at University of Kentucky utilizing the local American College of Surgeons National Surgical Quality Improvement Project database. PATIENTS: All patients ≥18 years of age who underwent colorectal resection for all indications, excluding trauma, between January 1, 2013, and December 31, 2016, were included. MAIN OUTCOME MEASURES: The primary outcomes measured were the rates of 30-day postoperative morbidity and mortality. RESULTS: Of 1201 patients, 30.2% used opioids, 18.4% used sedatives, and 28.3% used antidepressants preoperatively. Users of any medication class had higher ASA classification, rates of dyspnea, and severe chronic obstructive pulmonary disease than nonusers. Opioid users also had higher rates of ostomy creation, contaminated wound classification, prolonged operation time, and postoperative transfusion. Postoperatively, patients had higher rates of intra-abdominal infection (opioids: 21.5% vs 15.2%, p = 0.009; sedatives: 23.1% vs 15.7%, p = 0.01; antidepressants: 22.4% vs 15.0%, p = 0.003) and respiratory failure (opioids: 11.0% vs 6.3%, p = 0.007; sedatives: 12.2% vs 6.7%, p = 0.008; antidepressants: 10.9% vs 6.5%, p = 0.02). Reported opioid or sedative users had a prolonged hospital length of stay of 2 days (p < 0.001) compared with nonusers. After adjustment for all predictors of poor outcome, opioid and sedative use was associated with increased 30-day morbidity and mortality following colorectal procedures (OR, 1.43; 95% CI, 1.07-1.91 and OR, 1.48; 95% CI, 1.05-2.08). LIMITATIONS: This study was a retrospective review and a single-institution study, and it had unmeasured confounders. CONCLUSIONS: We identified that patient-reported prescription opioid and sedative use is associated with higher 30-day composite adverse outcomes in colorectal resections, highlighting the need for the evaluation of opioid and sedative use as a component of the preoperative risk stratification.

REVISIÓN RETROSPECTIVA: EL USO DE OPIOIDES, SEDANTES O ANTIDEPRESORES EN EL PREOPERATORIO SE ASOCIAN CON MALOS RESULTADOS EN CIRUGÍA COLORECTAL: El uso de opioides, sedantes y antidepresores esta en aumento. No se ha establecido el efecto de estos medicamentos en los resultados de la cirugía colorrectal.Evaluar el impacto del uso preoperatorio de opioides, sedantes y antidepresores en los resultados después de una cirugía colorrectal.Base de datos retrospectiva y revisión de registros médicos.Este estudio se realizó en la Universidad de Kentucky utilizando la base de datos del Proyecto de Mejora de Calidad Quirúrgica Nacional del Colegio Estadounidense de Cirujanos.Todos los pacientes ≥ 18 años que se sometieron a una resección colorrectal por diversas indicaciones, excluyendo los traumas, entre el 1 de Enero de 2013 y el 31 de Diciembre de 2016.Tasas de morbilidad y mortalidad postoperatorias a los 30 días.De 1201 pacientes, 30.2% usaron opioides, 18.4% usaron sedantes y 28.3% usaron antidepresores antes de la cirugía. Los pacientes tratados con cualquiera de los medicamentos mencionados, presentaban un ASA mas elevado, tasas de disnea y EPOC mas graves en comparación con pacientes sin tratamiento previo. Los consumidores de opioides también tuvieron tasas más altas de creación de ostomías, clasificación mas alta de heridas contaminadas, un tiempo de operación prolongado y transfusión postoperatoria mayor. Después de la cirugía los pacientes que tuvieron tasas más altas de infección intraabdominal (opioides: 21.5% vs 15.2%, p = 0.009, sedantes: 23.1% vs 15.7%, p = 0.01, antidepresivos: 22.4% vs 15.0%, p = 0.003) e insuficiencia respiratoria (opioides: 11.0% vs 6.3%, p = 0.007, sedantes: 12.2% vs 6.7%, p = 0.008, antidepresivos: 10.9% vs 6.5%, p = 0.02). Los consumidores de opioides o sedantes tuvieron una estadía hospitalaria prolongada de más de 2 días (p <0.001) en comparación con los consumidores. Después de haber realizado el ajuste de todos los predictores de mal pronóstico, el uso de opioides y sedantes se asoció con una mayor morbilidad y mortalidad a los 30 días después de cirugía colorrectal (OR 1.43 [IC 95% 1.07-1.91] y OR 1.48 [IC 95% 1.05-2.08], respectivamente)Revisión retrospectiva, estudio de una sola institución, factores de confusión no evaluados.Identificamos que el consumo de opiáceos y sedantes recetados a los pacientes se asocian con resultados adversos complejos más allá de 30 días en casos de resección colorrectal, destacando la necesidad de su respectiva evaluación como componentes de la estratificación de riesgo preoperatorio.
