Engaging Parents in Child-Focused Child Sexual Abuse Prevention Education Strategies: A Systematic Review.

Parents are their children's first teachers and there are long-standing calls for their involvement in child sexual abuse prevention. In this rapid systematic review, we asked the following questions: what rationales are used to justify parental involvement in child-focused child sexual abuse (CSA) prevention programs? what approaches are used for parental engagement in child-focused CSA prevention programs? and what are the facilitators and barriers to parental involvement in child-focused CSA prevention programs? We searched CINAHL, Cochrane, ERIC, Medline, PsycInfo, Scopus, and SocINDEX in May 2021. A total of 57 papers met our inclusion criteria, comprised of 50 empirical studies, and 7 program descriptions. Rationales for parental involvement included monitoring and shaping parental attitudes toward CSA program delivery in schools; reinforcing children's learning at home; promoting parent-child communication about CSA prevention; building parent capacity to respond to child disclosures; and supporting program delivery for preschoolers. Types of parental involvement included the following: communication, learning at home, volunteering, decision-making, and collaboration with the community. Barriers to parent involvement included ineffective program engagement modalities, and parental fears and misconceptions.

Supporting families of patients who die in adult intensive care: A scoping review of interventions.

BACKGROUND: Families who perceive themselves as prepared for an impending death experience reduced psychological burden during bereavement. Understanding which interventions promote death preparedness in families during end-of-life care in intensive care will inform future intervention development and may help limit the burden of psychological symptoms associated with bereavement. AIM: To identify and characterise interventions that help prepare families for the possibility of death in intensive care, incorporating barriers to intervention implementation, outcome variables and instruments used. DESIGN: Scoping review using Joanna Briggs methodology, prospectively registered and reported using relevant guidelines. DATA SOURCES: A systematic search of six databases from 2007 to 2023 for randomised controlled trials evaluating interventions that prepared families of intensive care patients for the possibility of death. Citations were screened against the inclusion criteria and extracted by two reviewers independently. RESULTS: Seven trials met eligibility criteria. Interventions were classified: decision support, psychoeducation, information provision. Psychoeducation involving physician-led family conference, emotional support and written information reduced symptoms of anxiety, depression, prolonged grief, and post-traumatic stress in families during bereavement. Anxiety, depression, and post-traumatic stress were assessed most frequently. Barriers and facilitators to intervention implementation were seldom reported. CONCLUSION: This review provides a conceptual framework of interventions to prepare families for death in intensive care, while highlighting a gap in rigorously conducted empirical research in this area. Future research should focus on theoretically informed, family-clinician communication, and explore the benefits of integrating existing multidisciplinary palliative care guidelines to deliver family conference within intensive care. IMPLICATIONS FOR CLINICAL PRACTICE: Intensive care clinicians should consider innovative communication strategies to build family-clinician connectedness in remote pandemic conditions. To prepare families for an impending death, mnemonic guided physician-led family conference and printed information could be implemented to prepare families for death, dying and bereavement. Mnemonic guided emotional support during dying and family conference after death may also assist families seeking closure.

Incidence and prevalence of hamstring injuries in field-based team sports: a systematic review and meta-analysis of 5952 injuries from over 7 million exposure hours.

OBJECTIVE: This study aimed to systematically review and meta-analyse the incidence and prevalence of hamstring injuries in field-based team sports. A secondary aim was to determine the impact of other potential effect moderators (match vs training; sport; playing surface; cohort age, mass and stature; and year when data was collected) on the incidence of hamstring injury in field-based team sports. DESIGN: Systematic review and meta-analysis. DATA SOURCES: CINAHL, Cochrane Library, MEDLINE Complete (EBSCO), Embase, Web of Science and SPORTDiscus databases were searched from database inception to 5 August 2020. ELIGIBILITY CRITERIA: Prospective cohort studies that assessed the incidence of hamstring injuries in field-based team sports. METHOD: Following database search, article retrieval and title and abstract screening, articles were assessed for eligibility against predefined criteria then assessed for methodological quality using the Critical Appraisal Tool for prevalence studies. Meta-analysis was used to pool data across studies, with meta-regression used where possible. RESULTS: Sixty-three articles were included in the meta-analysis, encompassing 5952 injuries and 7 262 168 hours of exposure across six field-based team sports (soccer, rugby union, field hockey, Gaelic football, hurling and Australian football). Hamstring injury incidence was 0.81 per 1000 hours, representing 10% of all injuries. Prevalence for a 9-month period was 13%, increasing 1.13-fold for every additional month of observation (p=0.004). Hamstring injury incidence increased 6.4% for every 1 year of increased average cohort age, was 9.4-fold higher in match compared with training scenarios (p=0.003) and was 1.5-fold higher on grass compared with artificial turf surfaces (p<0.001). Hamstring injury incidence was not significantly moderated by average cohort mass (p=0.542) or stature (p=0.593), was not significantly different between sports (p=0.150) and has not significantly changed over the last 30 years (p=0.269). CONCLUSION: Hamstring injury represents 10% of all injuries in field-based team sports, with 13% of the athletes experiencing a hamstring injury over a 9-month period most commonly during matches. More work is needed to reduce the incidence of hamstring injury in field-based team sports. PROSPERO REGISTRATION NUMBER: CRD42020200022.

Thermal preference does not align with optimal temperature for aerobic scope in zebrafish (Danio rerio).

Warming is predicted to have negative consequences for fishes by causing a mismatch between oxygen demand and supply, and a consequent reduction in aerobic scope (AS) and performance. This oxygen and capacity limited thermal tolerance (OCLTT) hypothesis features prominently in the literature but remains controversial. Within the OCLTT framework, we hypothesised that fish would select temperatures that maximise their AS, and thus their performance. We tested this hypothesis using intermittent flow respirometry to measure AS at, above (+2.5°C) and below (-2.5°C) the self-selected, preferred temperature (Tpref) of individual zebrafish (Danio rerio). AS was greatest 2.5°C above Tpref, which was driven by an increase in maximal metabolic rate. This mismatch between Tpref and the optimal temperature for AS suggests that factor(s) aside from AS maximisation influence the thermal preference of zebrafish.

Muscle Activity and Activation in Previously Strain-Injured Lower Limbs: A Systematic Review.

BACKGROUND: Lower limb muscle strain injury is highly prevalent in running-based sports and is considered a risk factor for recurrent injury. It is possible that differences in muscle activity and activation in previously strain-injured limbs may contribute to the elevated risk of reinjury. OBJECTIVES: To systematically review available literature investigating whether muscle activity and/or activation is different in previously strain-injured muscles compared to contralateral uninjured muscles or uninjured controls. METHODS: A systematic review of literature in SPORTDiscus, MEDLINE Complete, CINAHL and Web of Science was conducted. Full-text English articles which compared indicators of neuromuscular function between injured and uninjured contralateral limbs or control groups in those with a history of muscle strain injury were included. RESULTS: Twelve studies were included in the review after eligibility criteria were applied. A best evidence synthesis revealed moderate to limited evidence suggesting differences in surface electromyography (sEMG) amplitude, integrated sEMG amplitude, inter-muscle sEMG ratios and voluntary activation in injured limbs, most often during eccentric contractions. Studies utilising sprinting assessments demonstrated conflicting evidence when comparing late swing phase biceps femoris sEMG amplitude between limbs with a history of hamstring strain injury and uninjured contralateral limbs. CONCLUSIONS: Differences in muscle activity and activation were observed between injured and uninjured limbs across a variety of strength assessments. The evidence supporting these differences was most often moderate or limited and was generally observed during eccentric contractions. Mostly conflicting or limited evidence was found to suggest that participants with previous hamstring strain injury demonstrate no differences in muscle activity during running tasks when compared with their uninjured counterparts or contralateral limbs.

Does Site Matter? Impact of Inertial Measurement Unit Placement on the Validity and Reliability of Stride Variables During Running: A Systematic Review and Meta-analysis.

BACKGROUND: Inertial measurement units (IMUs) are used for running gait analysis in a variety of sports. These sensors have been attached at various locations to capture stride data. However, it is unclear if different placement sites affect the derived outcome measures. OBJECTIVE: The aim of this systematic review and meta-analysis was to investigate the impact of placement on the validity and reliability of IMU-derived measures of running gait. METHODS: Online databases SPORTDiscus with Full Text, CINAHL Complete, MEDLINE (EBSCOhost), EMBASE (Ovid) and Scopus were searched from the earliest record to 6 August 2020. Articles were included if they (1) used an IMU during running (2) reported spatiotemporal variables, peak ground reaction force (GRF) or vertical stiffness and (3) assessed validity or reliability. Meta-analyses were performed for a pooled validity estimate when (1) studies reported means and standard deviation for variables derived from the IMU and criterion (2) used the same IMU placement and (3) determined validity at a comparable running velocity (≤ 1 m·s-1 difference). RESULTS: Thirty-nine articles were included, where placement varied between the foot, tibia, hip, sacrum, lumbar spine (LS), torso and thoracic spine (TS). Initial contact, toe-off, contact time (CT), flight time (FT), step time, stride time, swing time, step frequency (SF), step length (SL), stride length, peak vertical and resultant GRF and vertical stiffness were analysed. Four variables (CT, FT, SF and SL) were meta-analysed, where CT was compared between the foot, tibia and LS placements and SF was compared between foot and LS. Foot placement data were meta-analysed for FT and SL. All data are the mean difference (MD [95%CI]). No significant difference was observed for any site compared to the criterion for CT (foot: - 11.47 ms [- 45.68, 22.74], p = 0.43; tibia: 22.34 ms [- 18.59, 63.27], p = 0.18; LS: - 48.74 ms [- 120.33, 22.85], p = 0.12), FT (foot: 11.93 ms [- 8.88, 32.74], p = 0.13), SF (foot: 0.45 step·min-1 [- 1.75, 2.66], p = 0.47; LS: - 3.45 step·min-1 [- 16.28, 9.39], p = 0.37) and SL (foot: 0.21 cm [- 1.76, 2.18], p = 0.69). Reliable derivations of CT (coefficient of variation [CV] < 9.9%), FT (CV < 11.6%) and SF (CV < 4.4%) were shown using foot- and LS-worn IMUs, while the CV was < 7.8% for foot-determined stride time, SL and stride length. Vertical GRF was reliable from the LS (CV = 4.2%) and TS (CV = 3.3%) using a spring-mass model, while vertical stiffness was moderately (r = 0.66) and nearly perfectly (r = 0.98) correlated with criterion measures from the TS. CONCLUSION: Placement of IMUs on the foot, tibia and LS is suitable to derive valid and reliable stride data, suggesting measurement site may not be a critical factor. However, evidence regarding the ability to accurately detect stride events from the TS is unclear and this warrants further investigation.
