How best to share research with study participants? : a randomised crossover trial comparing a comic, lay summary, and scientific abstract

Healthcare research is traditionally published in academic papers, coded in scientific language, and locked behind paywalls–an inaccessible form for many. Sharing research results with participants and the public in an appropriate, accessible manner, is an ethical practice directed in research guidance. Evidence-based recommendations for the medium used are scant, but science communication advice advocates principles which may be fulfilled well by the medium of comics. We report a randomised crossover study conducted online, comparing participant preferences for research results shared in the medium of a comic, a traditional lay text summary, and the control approach of a scientific abstract. 1236 respondents read all three summaries and ranked their most and least preferred formats. For the most preferred summary, the comic was chosen by 716 (57.9%), lay summary by 321 (26.0%), and scientific abstract by 199 (16.1%) respondents. For the least preferred summary the scientific abstract was chosen by 614 (49.7%), lay summary by 380 (30.7%) and comic by 242 (19.6%). Review of free-text responses identified key reasons for the majority preferring the comic over the others, which included finding this easier to read and understand, more enjoyable to consume, and more satisfactory as a medium of communication

What variables should inform needle length choice for deltoid intramuscular injection? A systematic review

Objectives (1) Assess the distribution of skin-to-deltoid-muscle distance (SDMD) at the deltoid intramuscular (IM) injection site; (2) its relationship with demographic and anthropometric variables and (3) Consider the findings in relation to clinical guidance on IM injection, such as COVID-19 vaccines.Design Systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.Data sources MEDLINE, EMBASE, ClinicalTrials.gov, Cochrane Library, CINAHL and SCOPUS between June and July 2021 with no publication date limit.Eligibility criteria Studies reporting measurements of the SDMD in living adults aged 16 years and older, at the deltoid IM injection site, published in English were considered.Data extraction and synthesis Two independent reviewers performed each stage of screening, data extraction and quality assessments using the Joanna Briggs Institute Critical Appraisal Checklist for analytical cross sectional studies.Results 16 105 papers were identified, of which 11 studies were suitable for review, representing 1414 participants. Heterogeneity in the definition of the deltoid IM injection site, locations measured and methods of measurement precluded meta-analysis. Evidence from ultrasound SDMD measurements demonstrated some patients in all but ‘underweight’ body mass index (BMI) categories, may require needles longer than 25 mm for successful IM injection. Calliper measurements overestimated SDMD compared with ultrasound. Female sex, higher BMI categories and greater weight in women were associated with greater SDMD.Conclusions The reviewed evidence was insufficient to inform definitive needle length ‘cut points’ for IM injection based on demographic or anthropomorphic variables. Contemporary clinical guidance currently based on this evidence, including the site of injection and choice of needle length, may result in subcutaneous administration in a small proportion of recipients, particularly if obese or of female sex.PROSPERO registration number CRD42021264625

Primary spinal infections in patients with solid organ transplant: a systematic literature review and illustrative case

BackgroundPrimary spinal infections (PSIs) are a group of uncommon but serious infectious diseases considered more prevalent and aggressive among patients with chronic immunocompromised states. Association of PSI and solid organ transplant has not been systematically analyzed. The authors performed a systematic review analyzing clinical presentation and mortality of patients with PSI in the setting of solid organ transplant.ObservationsPSIs in patients with immunosuppressive therapy, such as those with solid organ transplant, may behave differently in terms of epidemiology, clinical presentation, and outcomes compared with nonimmunosuppressed patients. Overall PSI in solid organ transplant patients is associated with a high rate of neurological compromise, postoperative complications, and mortality.LessonsAccurate diagnosis and appropriate treatment of PSI require a multidisciplinary effort. Localized pain is the most frequently reported symptom associated with PSI. As opposed to PSI in patients without transplant, inflammatory and infectious markers such as white blood cells and C-reactive protein are often not elevated. Furthermore, the causative microorganism profile varies significantly when compared to pyogenic spinal infection in patients without transplant. Aspergillus species was responsible for spondylodiscitis in transplant patients in more than 50% of cases, and the incidence of Aspergillus infection is projected to rise in the coming years

Pyogenic spinal infections in patients with chronic liver disease: illustrative case and systematic review.

BackgroundPyogenic spinal infections (PSIs) are a group of uncommon but serious infectious diseases that are characterized by inflammation of the endplate-disc unit. PSIs are considered more prevalent and aggressive among patients with chronic immunocompromised states. Association between PSIs and liver disease has not been systematically analyzed. The authors performed a systematic review to study baseline characteristics, clinical presentation, and mortality of patients with PSI in the setting of chronic liver disease.ObservationsThe authors presented the case of a 72-year-old female patient with chronic liver disease who presented with severe low back pain and bilateral lower weakness. Imaging studies showed T10-11 spondylodiscitis. The patient received decompression and fusion surgery with partial neurological improvement. The authors performed a systematic literature search of spondylodiscitis and liver disease, and eight published articles met the studies inclusion and exclusion criteria. These studies featured a total of 144 patients, of whom 129 met inclusion criteria (mean age, 60.5 years, range 40 to 83 years; 62% males). Lumbar infection was the most common report (67%), with Staphylococcus aureus (48%) as the main causative microorganism. Neurological compromise was present in 69% of patients. Surgical intervention occurred in 70.5% of patients, and the average duration of antibiotic treatment was 69.4 days. Postoperative complication rate was 28.5%, with a 30- and 90-day mortality of 17.2% and 24.8%, respectively.LessonsPyogenic spondylodiscitis in patients with liver disease was associated with a high rate of neurological compromise, postoperative complications, and mortality

Surgical treatment in primary spinal infections in a pediatric population: illustrative case

BackgroundPrimary spinal infections (PSIs) are a group of uncommon but serious infectious diseases that are characterized by inflammation of the endplate-disc unit. Pediatric spinal infection is rare and challenging to diagnose due to vague presenting symptoms. Most cases are conservatively managed with surgery rarely indicated. The authors performed a systematic review to study the baseline characteristics, clinical presentation, and outcomes of pediatric patients with PSIs who underwent surgical treatment.ObservationsPSI in pediatric patients might behave differently in terms of epidemiology, clinical presentation, and outcomes when compared with nonpediatric patients. Overall, PSI ultimately managed surgically in pediatric patients is associated with a high rate of localized pain, neurological compromise, and treatment failure when compared with nonsurgically managed pediatric spinal infections.LessonsPSIs managed surgically in the pediatric population were found to be caused by Mycobacterium tuberculosis in 74.4% of cases and were associated with higher rates of localized pain, neurological compromise, and treatment failure than nonsurgically managed pediatric spinal infections. Thoracic involvement (71.8%) in the spinal infection was reported most commonly in our review. When omitting the cases involving M. tuberculosis infection, it was revealed that 50% of the pediatric cases involved infection in the cervical region, suggesting increased severity and disease course of cervical spinal infections in the pediatric population. Surgical treatment is indicated only in cases of severe neurological compromise and treatment failure

Primary Spinal Infections in Patients With Hematologic Immunocompromising Conditions: A Systematic Literature Review

PurposePrimary spinal infections (PSIs) are a group of infectious diseases characterized by inflammation of the end plate-disk unit or its surroundings. PSI is considered more prevalent and aggressive among patients with chronic immunocompromised states. Association of PSIs, immunocompromising cancers, and hemoglobinopathies has not been systematically analyzed. We conducted a systematic review to study characteristics, clinical presentation, and mortality of patients with PSI in the setting of hematologic disease.MethodsA systematic literature search in PubMed, Web of Science, and Scopus was conducted in April 2022 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included retrospective case series and individual case reports.ResultsOn careful review, 28 articles published between 1970 and 2022 were selected. These studies featured 29 patients who met inclusion criteria (mean age 29 years, age range 1.5 to 67 years; 63.3% male). Lumbar infection was the most common location (65.5%), with Salmonella (24.1%) as the main causative microorganism. Neurologic compromise was present in 41% of patients, and surgical intervention occurred in 48.3%. Average antibiotic duration was 13 weeks. The postoperative complication rate was 21.4%, with a mortality of 6.9%.ConclusionPSI in patients with hematologic disease, while having shorter periods to diagnosis, presents increased rates of neurologic deficit, surgical intervention, and complications

Asthma control with ICS-formoterol reliever versus maintenance ICS and SABA reliever therapy: a post hoc analysis of two randomised controlled trials

Background: In randomised controlled trials, as-needed inhaled corticosteroid (ICS)-formoterol reliever therapy reduces severe exacerbation risk compared with maintenance ICS plus short-acting beta2-agonist (SABA) reliever in adolescent and adult asthma, but results in slightly worse control of asthma symptoms, as measured by mean Asthma Control Questionnaire-5 (ACQ-5) score. Objective: To assess the levels and changes in asthma control for as-needed budesonide-formoterol versus maintenance budesonide plus SABA in post hoc analyses from the Novel START and PRACTICAL clinical trials. Methods: The number and proportion of participants at study end in each ACQ-5 category ('well-controlled', 'partly controlled' or 'inadequately controlled' symptoms), and in each responder category based on the minimal clinically important difference for ACQ-5 of 0.5 (improved, no change and worse) with as-needed budesonide-formoterol and maintenance budesonide plus SABA treatment were calculated. Results: With last observation carried forwards, 189/214 (88.3%) and 354/434 (81.6%) of patients in the budesonide-formoterol group had 'well-controlled' or 'partly controlled' symptoms at the end of the study, vs 183/214 (85.5%) and 358/431 (83.1%) in the budesonide maintenance group, for Novel START and PRACTICAL, respectively. The proportion of patients whose symptom control was either improved or unchanged from baseline was 190/214 (88.8%) and 368/434 (84.8%) for budesonide-formoterol, vs 185/214 (86.4%) and 376/431 (87.2%) for maintenance budesonide, in Novel START and PRACTICAL respectively. Conclusions: There were no clinically important differences in the proportions of patients with 'well-controlled' or 'partly controlled' asthma symptoms, or proportions who improved or maintained their level of control, with as-needed budesonide-formoterol versus maintenance budesonide plus SABA

The Anti-Inflammatory Reliever (AIR) Algorithm Study: a protocol for a single-group study of an AIR stepwise approach to the treatment of adult asthma

Background The stepwise approach to long-term asthma management, which traditionally incorporates short-acting β2-agonist reliever therapy, has been a core feature of asthma guidelines for over 30 years. There have been no studies, however, directly investigating the use of an entire guideline-recommended track. Recently, inhaled corticosteroid–formoterol has been recommended as the preferred reliever therapy in adult asthma, in accordance with a stepwise “Anti-Inflammatory Reliever” (AIR) treatment track. Objective The aim of this study was to evaluate the AIR stepwise approach recommended by the New Zealand adolescent and adult asthma guidelines, in combination with a novel algorithm for transitioning between treatment steps. Methods This 52-week, open-label, single-group study will recruit 100 adults aged 18 to 75 years with mild, moderate and moderate–severe asthma (ACTRN12620001010987). Participants will be allocated to budesonide–formoterol 200/6 µg, one actuation as needed (Step 1), one actuation twice daily and as needed (Step 2), or two actuations twice daily and one as needed (Step 3). Treatment steps will be adjusted throughout the study, in response to reliever use and asthma attacks, according to a stepwise AIR algorithm. Following a 26-week period of investigator-led transitions, participants will adjust their own treatment step. The primary outcome is participant satisfaction as measured by the Global Satisfaction score of the Treatment Satisfaction Questionnaire for Medication. Secondary outcomes will assess efficacy and safety, and describe patterns of medication use and participant flow through the treatment steps. Conclusion This is the first trial to assess the AIR treatment track and algorithm. The results will provide knowledge to guide the clinical use of this approach

A Study of Stereotyping: Testing Three Models With a Sample of Blacks

Two experiments tested the premise that the underlying stereotyping processes used by Blacks and Whites are similar Experiment I examined the hypothesis that people have more complex views of members of their own in-group than of an out-group. Results showed that Blacks held more complex views of Blacks than of Whites. Experiment 2 examined the hypotheses underlying complexity-extremity theory, assumed-characteristics theory, and expectancy-violation theory. Black perceivers evaluated target job applicants who varied with respect to race, dialect style, and personal appearance. Contrary to the complexity-extremity model, Black judges evaluated Black targets more extremely than White targets. Somewhat consistent with assumed-characteristics theory, Blacks used background information more than race in their evaluations. Partial support for expectancy-violation theory wasfound. Blackjudges evaluated upper class Black and White targets differently than they evaluated lower class targets. These findings suggest that race of perceiver may moderate the predictions of these three models. Modification of stereotyping models by including less powerful or stigmatized in-groups in basic research is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66586/2/10.1177_00957984950214004.pd
