Educating and Empowering Inner-City High School Students in Bleeding Control.

INTRODUCTION: Unintentional bleeding is the leading cause of death in people 1-44 years of age in the United States. The Stop the Bleed (STB) campaign is a nationwide course that teaches the public to ensure their own safety, call 911, find the bleeding injury, and achieve temporary hemorrhage control by several techniques. Although the national campaign for the training course was inspired by active shooter events, the training can be applied to motor vehicle accidents and small-scale penetrating and gunshot wounds. Extending the audience to inner-city high school students in a violence-prone neighborhood has the potential to save lives if they are first on the scene. OBJECTIVES: We hypothesized that students would have a greater degree of comfort, willingness, and preparedness to intervene in acute bleeding after taking the course. METHODS: This was a prospective, interventional pilot study in one inner-city high school in Brooklyn, New York. Students were given the option to participate in the STB course with pre- and post-surveys. We recruited 286 students from physical education or health education class to take a 50-minute bleeding control training course. Mean age was 15.7 years old. Students were divided into groups of 20-25 and taught by 2-3 emergency medicine, pediatric, or trauma surgery STB instructors. Each course included 2-3 skills stations for placing a tourniquet, wound packing, and pressure control. RESULTS: Prior to the course, only 43.8% of the students reported being somewhat likely or very likely to help an injured person who was bleeding. After the course, this increased to 80.8% of students even if no bleeding control kit was available. Additionally, there were significant improvements in self-rated comfort level from pre- to post-course 45.4% to 76.5%, and in self-rated preparedness from 25.1% to 83.8%. All three measures showed statistically significant improvement, P <.0001. CONCLUSION: Teaching the STB course to high school students from a community with high levels of violence resulted in increased comfort level, willingness, and preparedness to act to control bleeding. If these opinions translate into action, students' willingness to act could decrease pre-hospital blood loss and empower youth to perform life-saving interventions.

Modafinil for people with schizophrenia or related disorders.

BACKGROUND: People with schizophrenia have a range of different symptoms, including positive symptoms (hallucinations and delusions), negative symptoms (such as social withdrawal and lack of affect), and cognitive impairment. The standard medication for people with schizophrenia is antipsychotics. However, these medications may not be effective for all symptoms of schizophrenia, as cognitive and negative symptoms are usually hard to treat. Additional therapies or medications are available for the management of these symptoms. Modafinil, a wakefulness-promoting agent most frequently used in narcolepsy or shift work sleep disorder, is one intervention that is theorised to have an effect of these symptoms. OBJECTIVES: The primary objective of this review was to assess the effects of modafinil for people with schizophrenia or related disorders. SEARCH METHODS: On 27 April 2015, 24 May 2017, and 31 October 2019, we searched the Cochrane Schizophrenia Group's register of trials, which is based on regular searches of CENTRAL, MEDLINE, Embase, AMED, BIOSIS, CINAHL, PsycINFO, PubMed, and registries of clinical trials. There are no language, time, document type, or publication status limitations for the inclusion of records in the register. SELECTION CRITERIA: We selected all randomised controlled trials comparing modafinil with placebo or other treatments for people with schizophrenia or schizophrenia-spectrum disorders. DATA COLLECTION AND ANALYSIS: We independently extracted data from the included studies. We analysed dichotomous data using risk ratios (RR) and 95% confidence intervals (CI). We analysed continuous data using mean difference (MD) with a 95% CI. We used a random-effects model for the meta-analysis. We used GRADE to complete a 'Summary of findings' table and assessed risk of bias for the included studies. MAIN RESULTS: Eleven studies including a total of 422 participants contributed to data analyses. Most studies had a small population size (average 38 people per study) and were of short duration. We also detected a high risk of bias for selective outcome reporting in just under 50% of the trials. We therefore rated the overall methodological quality of the included studies as low. We considered seven main outcomes of interest: clinically important change in overall mental state, clinically important change in cognitive functioning, incidence of a clinically important adverse effect/event, clinically important change in global state, leaving the study early for any reason, clinically important change in quality of life, and hospital admission. All studies assessed the effects of adding modafinil to participants' usual antipsychotic treatment compared to adding placebo to usual antipsychotic treatment. Six studies found that adding modafinil to antipsychotic treatment may have little or no effect on overall mental state of people with schizophrenia, specifically the risk of worsening psychosis (RR 0.91, 95% CI 0.28 to 2.98; participants = 209; studies = 6, low-quality evidence). Regarding the effect of modafinil on cognitive function, the trials did not report clinically important change data, but one study reported endpoint scores on the MATRICS Consensus Cognitive Battery (MCCB): in this study we found no clear difference in scores between modafinil and placebo treatment groups (MD -3.10, 95% CI -10.9 to 4.7; participants = 48; studies = 1, very low-quality evidence). Only one study (N = 35) reported adverse effect/event data. In this study one serious adverse event occurred in each group (RR 0.84, 95% CI 0.06 to 12.42; participants = 35; studies = 1, very low-quality evidence). One study measured change in global state using the Clinical Global Impression - Improvement Scale. This study found that adding modafinil to antipsychotic treatment may have little or no effect on global state (RR 6.36, 95% CI 0.94 to 43.07, participants = 21; studies = 1, very low-quality evidence). Nine studies found that modafinil has no effect on numbers of participants leaving the study early (RR 1.26, 95% CI 0.63 to 2.52 participants = 357; studies = 9, moderate-quality evidence). None of the trials reported clinically important change in quality of life, but one study did report quality of life using endpoint scores on the Quality of Life Inventory, finding no clear difference between treatment groups (MD -0.2, 95% CI -1.18 to 0.78; participants = 20; studies = 1, very low-quality evidence). Finally, one study reported data for number of participants needing hospitalisation: one participant in each group was hospitalised (RR 0.84, 95% CI 0.06 to 12.42; participants = 35; studies = 1, very low-quality evidence). AUTHORS' CONCLUSIONS: Due to methodological issues, low sample size, and short duration of the clinical trials as well as high risk of bias for outcome reporting, most of the evidence available for this review is of very low or low quality. For results where quality is low or very low, we are uncertain or very uncertain if the effect estimates are true effects, limiting our conclusions. Specifically, we found that modafinil is no better or worse than placebo at preventing worsening of psychosis; however, we are uncertain about this result. We have more confidence that participants receiving modafinil are no more likely to leave a trial early than participants receiving placebo. However, we are very uncertain about the remaining equivocal results between modafinil and placebo for outcomes such as improvement in global state or cognitive function, incidence of adverse events, and changes in quality of life. More high-quality data are needed before firm conclusions regarding the effects of modafinil for people with schizophrenia or related disorders can be made.
