The Effects of Rest on Concussion Symptom Resolution and Recovery Time: A Meta-analytic Review and Subgroup Analysis of 4329 Patients.

BACKGROUND: Numerous individual studies suggest that rest may have a negative effect on outcomes following concussion. PURPOSE: To perform a systematic meta-analysis of the effects of prescribed rest compared with active interventions after concussion. STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: A meta-analysis (using the Hedges g) of randomized controlled trials and cohort studies was conducted to evaluate the effects of prescribed rest on symptoms and recovery time after concussion. Subgroup analyses were performed for methodological, study, and sample characteristics. Data sources were obtained from systematic search of key terms using Ovid Medline, Embase, Cochrane Database of Systematic Reviews, APA PsycINFO, Web of Science, SPORTDiscus, and ProQuest dissertations and theses through May 28, 2021. Eligible studies were those that (1) assessed concussion or mild traumatic brain injury; (2) included symptoms or days to recovery for ≥2 time points; (3) included 2 groups with 1 group assigned to rest; and (4) were written in the English language. RESULTS: In total, 19 studies involving 4239 participants met criteria. Prescribed rest had a significant negative effect on symptoms (k = 15; g = -0.27; SE = 0.11; 95% CI, -0.48 to -0.05; P = .04) but not on recovery time (k = 8; g = -0.16; SE = 0.21; 95% CI, -0.57 to 0.26; P = .03). Subgroup analyses suggested that studies with shorter duration (<28 days) (g = -0.46; k = 5), studies involving youth (g = -0.33; k = 12), and studies focused on sport-related concussion (g = -0.38; k = 8) reported higher effect sizes. CONCLUSION: The findings support a small negative effect for prescribed rest on symptoms after concussion. Younger age and sport-related mechanisms of injury were associated with a greater negative effect size. However, the lack of support for an effect for recovery time and the relatively small overall numbers of eligible studies highlight ongoing concerns regarding the quantity and rigor of clinical trials in concussion.

Prevention of Lower Extremity Musculoskeletal Injuries in Tactical and First Responder Populations: A Systematic Review and Meta-Analysis of Randomized Trials From 1955 to 2020.

ABSTRACT: Sinnott, AM, Krajewski, KT, LaGoy, AD, Beckner, ME, Proessl, F, Canino, MC, Nindl, BC, Turner, RL, Lovalekar, MT, Connaboy, C, and Flanagan, SD. Prevention of lower extremity musculoskeletal injuries in tactical and first responder populations: A systematic review and meta-analysis of randomized trials from 1955 to 2020. J Strength Cond Res 37(1): 239-252, 2023-Lower extremity musculoskeletal injuries (LEMSIs) impose a significant burden on tactical and first responder populations. To determine the effectiveness of LEMSI prevention strategies, we performed a systematic review and meta-analysis of randomized controlled trials published in English from 1955 to 2020 (PROSPERO: CRD42018081799). MEDLINE, EMBASE, Cochrane, CINAHL, ProQuest, and DTIC databases were searched for trials that assigned military service members, police, firefighters, or paramedics to LEMSI prevention interventions with a minimum surveillance period of 12 weeks. Evidence was synthesized as odds ratios (OR) for LEMSI occurrence between individuals assigned to interventions and those assigned to standard activities. Risk of bias was assessed with the Cochrane Risk of Bias tool 2.0. Random-effects meta-analyses were conducted for (a) physical training and (b) footwear modifications to reduce LEMSI and (c) footwear modifications to reduce stress fractures specifically. Certainty in the body of evidence was determined with the GRADE approach. Of 28,499 records, 18 trials comprised of more than 11,000 subjects were synthesized. Interventions included physical training (8, N = 6,838), footwear modifications (8, N = 3,792), nutritional supplementation (1, N = 324), and training modifications (1, N = 350). Overall risk of bias was generally moderate ( N = 7 of 18) or high ( N = 9 of 18). Physical training (OR = 0.87, 95% CI [0.71, 1.08], p = 0.22, I 2 = 58.4%) and footwear modification (OR = 1.13, 95% CI [0.85, 1.49], p = 0.42, I 2 = 0.0%) did not reduce LEMSI or stress fractures (OR = 0.76, 95% CI [0.45, 1.28], p = 0.30, I 2 = 70.7%). Our results indicate that there is weak evidence to support current LEMSI prevention strategies. Future efforts will benefit from longer surveillance periods, assessment of women and nonmilitary populations, improved methodological rigor, and a greater breadth of approaches.

Mini-review: Robotic wheelchair taxonomy and readiness.

Robotic wheelchair research and development is a growing sector. This article introduces a robotic wheelchair taxonomy, and a readiness model supported by a mini-review. The taxonomy is constructed by power wheelchair and, mobile robot standards, the ICF and, PHAATE models. The mini-review of 2797 articles spanning 7 databases produced 205 articles and 4 review articles that matched inclusion/exclusion criteria. The review and analysis illuminate how innovations in robotic wheelchair research progressed and have been slow to translate into the marketplace.

A Systematic Review of Tools Assessing the Perspective of Caregivers of Residents With Dementia.

In collaboration with stakeholders, we conducted a systematic review of psychometric evidence for self-report tools measuring the perspective of family caregivers of nursing home residents with dementia. Our rationale for this review was based on evidence that nonpharmacological interventions can ameliorate dementia symptoms in nursing home residents. Such interventions require caregiver participation, which is influenced by perspectives. Yet, no existing tool measures the multidomain caregiver perspective. Our review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. The final sample included 42 articles describing 33 tools measuring domains of nursing home dementia care such as behavioral and psychological symptoms of dementia, resident quality of life, dementia-specific knowledge, communication, and medication use. We uncovered evidence gaps for tools measuring dementia-specific knowledge, communication, and medication use, all of which were important to our stakeholders. Future research should focus on development of psychometrically sound tools in alignment with the multidomain caregiver perspective.

Does the evidence support brief (≤30-mins), moderate (31-60-mins), or long duration naps (61+ mins) on the night shift? A systematic review.

We performed a systematic review of four databases to determine if the evidence supports a short or long duration nap during night shifts to mitigate fatigue, and/or improve health, safety, or performance for emergency services and public safety personnel (PROSPERO CRD42020156780). We focused on experimental research and evaluated the quality of evidence with the grading of recommendations, assessment, development, and evaluation (GRADE) framework. We used the Cochrane Collaboration's risk of bias tool to assess bias and reported findings using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Our search yielded n = 10,345 records and n = 44 were reviewed in full-text. Inter-rater agreement during screening was substantial (Kappa = 0.66). We retained n = 11 publications, reporting on n = 7 experimental studies with a cumulative sample size of n = 140. We identified wide variation in study design, napping interventions (i.e., timing, placement, and duration), and outcomes. We identified mixed findings comparing brief, moderate, and long duration naps on outcomes of interest. All seven studies presented serious risk of bias and the quality of evidence was rated as low. Based on the best available evidence, decisions regarding nap duration during night shift work should be based on time (post-nap) and outcome.

The experiences, priorities, and perceptions of informal caregivers of people with dementia in nursing homes: A scoping review.

BACKGROUND: Person-centered care has been shown to increase desired outcomes for people with dementia, yet informal caregivers' dissatisfaction with care is often reported. For those living in a nursing home, informal caregivers are uniquely situated to provide key insights into the individual's care. However, little is known of the informal caregivers' perspective, which hinders efforts to improve their satisfaction with person-centered nursing home care. Thus, we examined the comprehensive experiences, priorities, and perceptions of informal caregivers of nursing home residents with dementia. METHODS: In collaboration with stakeholders, a scoping review of Medline (Ovid), EMBASE.com, CINAHL (EBSCO), the Cochrane Library (Wiley), and PsycINFO (Ovid) databases from January 2000 to July 2020 was conducted. Data were extracted reflecting the experiences, priorities, and preferences of caregivers of people with dementia residing in nursing homes. RESULTS: We identified 114 articles that revealed nine themes: (1) communication, (2) transition to nursing home, (3) quality of care, (4) quality of life, (5) informal caregiver role, (6) knowledge of dementia, (7) end-of-life preferences, (8) medication use to manage neuropsychiatric behaviors, and (9) finances. CONCLUSION: Informal caregivers described aspects of care that led to both positive and negative experiences with and perceptions of nursing home care. The shortcomings in communication were discussed most frequently, indicating a high priority area. While researchers define the identified themes individually, informal caregivers perceive them to be interwoven as they relate to person-centered care delivery. Although we did not assess the quality of included articles, by identifying themes relevant to caregivers' perspectives of nursing home care, our findings may help to inform efforts to optimize caregivers' satisfaction with nursing home care for residents with dementia.

Impact of shift work on blood pressure among emergency medical services clinicians and related shift workers: A systematic review and meta-analysis.

BACKGROUND: Compared to day workers, shift workers face an elevated risk of cardiovascular disease. We reviewed the evidence to address the research question: Does acute exposure to shift work impact (blunt) the natural drop (dip) in Blood Pressure (BP) occurring during sleep and/or nighttime hours? (PROSPERO CRD42018110847). METHODS: We performed a systematic review of five databases. We compared pooled estimates of mean BP stratified by periods of shift work, rest/leisure, and sleep, and evaluated the quality of evidence with the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. RESULTS: Our search covered 1/1/1980-10/24/2018 and yielded 1,636 records. Inter-rater agreement during screening was high (Kappa=0.87). We retained 44 studies described in 50 publications. We identified wide variation in shift worker type, shift schedules, and regularity of BP measurements. Most studies examined BP during one shift workday and one rest/leisure day. No study examined the impact of repeated exposure to shift work on the sleep-related dip in BP. Eighteen studies examined night shifts and one reported on BP during sleep post night shift. Compared to BP measured during shift work, BP measured during any sleep period separate from shift work was lower by 17.5 mmHg Systolic BP (95%CI 15.75, 19.27) and 15.4 mmHg lower for Diastolic BP (95%CI 14.38, 16.42) (p < 0.05). CONCLUSIONS: There is limited research exploring the acute and long-term impact of shift work on BP during sleep. The available evidence is heterogenous, low quality, and suggests that the mean dip in BP during sleep separate from shift work is not blunted.

Assessments for Caregivers of Hospitalized Older Adults.

A systematic review was conducted to characterize assessments for caregivers of hospitalized older adults. Electronic literature searches of Medline, PsycINFO, and CINAHL of articles on caregiver assessments published in English between 2006 and present were completed. Thirty-three articles underwent full-text review; four included assessments designed to capture caregiver needs in hospital settings. Original articles on the development of these assessments were reviewed for quality appraisal. Four findings emerged from our review. Existing assessments (a) focus on caregivers of specific conditions of older adults, (b) contain a singular caregiving domain, (c) measure caregiver outcomes or simply describe caregiving experiences, and (d) neglect psychometric properties. Health care providers are limited in their selection of assessments with caregivers of hospitalized older adults. This barrier is problematic if we are to equip caregivers to be successful at providing care to older adults. Future research should develop a hospital assessment for caregivers.

Does evidence support "banking/extending sleep" by shift workers to mitigate fatigue, and/or to improve health, safety, or performance? A systematic review.

BACKGROUND: Sleep deprivation is common in shift work occupations, including safety-sensitive occupations. While extending sleep prior to scheduled shifts (i.e., "banking sleep") may be an intuitive strategy for fatigue mitigation, the evidence behind this strategy is unclear. METHODS: We performed a systematic review of literature retrieved in searches of four databases. We examined agreement between two independent screeners, abstracted key findings, reviewed and synthesized findings, and evaluated the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. The Cochrane Collaboration's risk of bias tool was used to evaluate bias of individual studies. We reported findings as prescribed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: Of the 3007 records screened, five met inclusion criteria. The inter-rater agreement for inclusion/exclusion was high (κ = 0.87). One study addressed patient safety outcomes. Four studies assessed the impact of banking sleep on performance, five assessed measures of acute fatigue, and three evaluated banking sleep on indicators of health. All five studies presented a very serious risk of bias and the quality of evidence was very low. Given these caveats, the findings, in aggregate, support banking sleep as a strategy to improve indicators of performance and acute fatigue. CONCLUSIONS: This systematic review identifies gaps in research of shift workers on the efficacy of banking sleep as a fatigue risk management strategy. The available evidence supports banking sleep prior to shiftwork as a strategy for improved patient safety, performance, and reducing acute fatigue.

Leaving the Lecture Behind: Putting PubMed Instruction into the Hands of the Students.

This column describes the development of a one-shot PubMed instruction class for medical students at a health sciences library. Background information on the objective is presented and discussed in the context of educational practice literature. The new course design centers on a guided group method of instruction in order to integrate more active learning. Surveyed students reported that the method was an effective way to learn how to search PubMed and that they preferred it to a traditional lecture. Pros and cons of the method are offered for other health sciences libraries interested in presenting PubMed instruction in a similar manner.

Risk Factors for Asparaginase-associated Pancreatitis: A Systematic Review.

GOALS: To evaluate potential risk factors for the development of asparaginase-associated pancreatitis (AAP), we performed a systematic review of the current literature from January 1946 through May 2015. BACKGROUND: Asparaginase, a primary treatment for the most common childhood cancer, acute lymphoblastic leukemia (ALL), is a well-described cause of pancreatitis. Further, pancreatitis is among the most burdensome and common complications of asparaginase treatment and represents a major reason for early-drug termination and inferior outcomes. The literature lacks clarity about the risk factors for AAP, and this knowledge gap has hampered the ability to reliably predict which patients are likely to develop AAP. STUDY: In an expansive screen, 1842 citations were funneled into a review of 59 full articles, of which 10 were deemed eligible based on predetermined inclusion criteria. RESULTS: Of the 10 identified studies, only 2 studies showed that children above 10 years of age had a >2-fold risk of AAP compared with younger children. Patients placed in high-risk ALL categories had a greater incidence of pancreatitis in 2 studies. In addition, use of pegylated asparaginase resulted in a higher incidence of AAP in 1 study. CONCLUSIONS: In this systematic review, older age, asparaginase formulation, higher ALL risk stratification, and higher asparaginase dosing appear to play a limited role in the development of AAP. Further studies are needed to probe the underlying mechanisms contributing to the development of pancreatitis in patients receiving asparaginase.
