Review
Habitual footwear use has been reported to influence foot structure with an acute exposure being shown to alter foot position and mechanics. The foot is highly specialised thus these changes in structure/position could influence functionality. This review aims to investigate the effect of footwear on gait, specifically focussing on studies that have assessed kinematics, kinetics and muscle activity between walking barefoot and in common footwear. In line with PRISMA and published guidelines, a literature search was completed across six databases comprising Medline, EMBASE, Scopus, AMED, Cochrane Library and Web of Science. Fifteen of 466 articles met the predetermined inclusion criteria and were included in the review. All articles were assessed for methodological quality using a modified assessment tool based on the STROBE statement for reporting observational studies and the CASP appraisal tool. Walking barefoot enables increased forefoot spreading under load and habitual barefoot walkers have anatomically wider feet. Spatial-temporal differences including, reduced step/stride length and increased cadence, are observed when barefoot. Flatter foot placement, increased knee flexion and a reduced peak vertical ground reaction force at initial contact are also reported. Habitual barefoot walkers exhibit lower peak plantar pressures and pressure impulses, whereas peak plantar pressures are increased in the habitually shod wearer walking barefoot. Footwear particularly affects the kinematics and kinetics of gait acutely and chronically. Little research has been completed in older age populations (50+ years) and thus further research is required to better understand the effect of footwear on walking across the lifespan.

Executive Summary: International Clinical Practice Guidelines for Pediatric Ventilator Liberation, A Pediatric Acute Lung Injury and Sepsis Investigators (PALISI) Network Document.
Pediatric-specific ventilator liberation guidelines are lacking despite the many studies exploring elements of extubation readiness testing. The lack of clinical practice guidelines has led to significant and unnecessary variation in methods used to assess pediatric patients' readiness for extubation. Twenty-six international experts comprised a multiprofessional panel to establish pediatrics-specific ventilator liberation clinical practice guidelines, focusing on acutely hospitalized children receiving invasive mechanical ventilation for more than 24 hours. Eleven key questions were identified and first prioritized using the Modified Convergence of Opinion on Recommendations and Evidence. A systematic review was conducted for questions that did not meet an threshold of ⩾80% agreement, with Grading of Recommendations, Assessment, Development, and Evaluation methodologies applied to develop the guidelines. The panel evaluated the evidence and drafted and voted on the recommendations. Three questions related to systematic screening using an extubation readiness testing bundle and a spontaneous breathing trial as part of the bundle met Modified Convergence of Opinion on Recommendations criteria of ⩾80% agreement. For the remaining eight questions, five systematic reviews yielded 12 recommendations related to the methods and duration of spontaneous breathing trials, measures of respiratory muscle strength, assessment of risk of postextubation upper airway obstruction and its prevention, use of postextubation noninvasive respiratory support, and sedation. Most recommendations were conditional and based on low to very low certainty of evidence. This clinical practice guideline provides a conceptual framework with evidence-based recommendations for best practices related to pediatric ventilator liberation.

Meta-Analysis Review
CONTEXT
Parents may experience psychological distress when a child is acutely hospitalized, which can negatively affect child outcomes. Interventions designed to support parents' coping have the potential to mitigate this distress.
OBJECTIVE
To describe interventions designed to provide coping support to parents of hospitalized children and conduct a meta-analysis of coping support intervention outcomes (parent anxiety, depression, and stress).
DATA SOURCES
We searched Pubmed, Embase, PsycINFO, Psychiatry Online, and Cumulative Index to Nursing and Allied Health Literature from 1985 to 2016 for English-language articles including the concepts "pediatric," "hospitalization," "parents," and "coping support intervention."
STUDY SELECTION
Two authors reviewed titles and abstracts to identify studies meeting inclusion criteria and reviewed full text if a determination was not possible using the title and abstract. References of studies meeting inclusion criteria were reviewed to identify additional articles for inclusion.
DATA EXTRACTION
Two authors abstracted data and assessed risk of bias by using a structured instrument.
RESULTS
Initial searches yielded 3450 abstracts for possible inclusion. Thirty-two studies met criteria for inclusion in the systematic review and 12 studies met criteria for inclusion in the meta-analysis. The most commonly measured outcomes were parent depression, anxiety, and stress symptoms. In meta-analysis, combined intervention effects significantly reduced parent anxiety and stress but not depression. Heterogeneity among included studies was high.
LIMITATIONS
Most included studies were conducted at single centers with small sample sizes.
CONCLUSIONS
Coping support interventions can alleviate parents' psychological distress during children's hospitalization. More evidence is needed to determine if such interventions benefit children.

Meta-Analysis Review
BACKGROUND
Infant acute pain and distress is commonplace. Infancy is a period of exponential development. Unrelieved pain and distress can have implications across the lifespan. This is an update of a previously published review in the Cochrane Database of Systematic Reviews, Issue 10 2011 entitled 'Non-pharmacological management of infant and young child procedural pain'.
OBJECTIVES
To assess the efficacy of non-pharmacological interventions for infant and child (up to three years) acute pain, excluding kangaroo care, and music. Analyses were run separately for infant age (preterm, neonate, older) and pain response (pain reactivity, immediate pain regulation).
SEARCH METHODS
For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 2 of 12, 2015), MEDLINE-Ovid platform (March 2015), EMBASE-OVID platform (April 2011 to March 2015), PsycINFO-OVID platform (April 2011 to February 2015), and CINAHL-EBSCO platform (April 2011 to March 2015). We also searched reference lists and contacted researchers via electronic list-serves. New studies were incorporated into the review. We refined search strategies with a Cochrane-affiliated librarian. For this update, nine articles from the original 2011 review pertaining to Kangaroo Care were excluded, but 21 additional studies were added.
SELECTION CRITERIA
Participants included infants from birth to three years. Only randomised controlled trials (RCTs) or RCT cross-overs that had a no-treatment control comparison were eligible for inclusion in the analyses. However, when the additive effects of a non-pharmacological intervention could be assessed, these studies were also included. We examined studies that met all inclusion criteria except for study design (e.g. had an active control) to qualitatively contextualize results. There were 63 included articles in the current update.
DATA COLLECTION AND ANALYSIS
Study quality ratings and risk of bias were based on the Cochrane Risk of Bias Tool and GRADE approach. We analysed the standardized mean difference (SMD) using the generic inverse variance method.
MAIN RESULTS
Sixty-three studies, with 4905 participants, were analysed. The most commonly studied acute procedures were heel-sticks (32 studies) and needles (17 studies). The largest SMD for treatment improvement over control conditions on pain reactivity were: non-nutritive sucking-related interventions (neonate: SMD -1.20, 95% CI -2.01 to -0.38) and swaddling/facilitated tucking (preterm: SMD -0.89; 95% CI -1.37 to -0.40). For immediate pain regulation, the largest SMDs were: non-nutritive sucking-related interventions (preterm: SMD -0.43; 95% CI -0.63 to -0.23; neonate: SMD -0.90; 95% CI -1.54 to -0.25; older infant: SMD -1.34; 95% CI -2.14 to -0.54), swaddling/facilitated tucking (preterm: SMD -0.71; 95% CI -1.00 to -0.43), and rocking/holding (neonate: SMD -0.75; 95% CI -1.20 to -0.30). Fifty two of our 63 trials did not report adverse events. The presence of significant heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of very low quality evidence.
AUTHORS' CONCLUSIONS
There is evidence that different non-pharmacological interventions can be used with preterms, neonates, and older infants to significantly manage pain behaviors associated with acutely painful procedures. The most established evidence was for non-nutritive sucking, swaddling/facilitated tucking, and rocking/holding. All analyses reflected that more research is needed to bolster our confidence in the direction of the findings. There are significant gaps in the existing literature on non-pharmacological management of acute pain in infancy.

Review
BACKGROUND
Comprehensive Geriatric Assessment (CGA) is a multidimensional interdisciplinary diagnostic process focused on determining an older person's medical, psychological and functional capability in order to develop a co-ordinated and integrated care plan. CGA is not limited simply to assessment, but also directs a holistic management plan for older people, which leads to tangible interventions. While there is established evidence that CGA reduces the likelihood of death and disability in acutely unwell older people, the effectiveness of CGA for community-dwelling, frail, older people at risk of poor health outcomes is less clear.
OBJECTIVES
To determine the effectiveness of CGA for community-dwelling, frail, older adults at risk of poor health outcomes in terms of mortality, nursing home admission, hospital admission, emergency department visits, serious adverse events, functional status, quality of life and resource use, when compared to usual care.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, CINAHL, three trials registers (WHO ICTRP, ClinicalTrials.gov and McMaster Aging Portal) and grey literature up to April 2020; we also checked reference lists and contacted study authors.
SELECTION CRITERIA
We included randomised trials that compared CGA for community-dwelling, frail, older people at risk of poor healthcare outcomes to usual care in the community. Older people were defined as 'at risk' either by being frail or having another risk factor associated with poor health outcomes. Frailty was defined as a vulnerability to sudden health state changes triggered by relatively minor stressor events, placing the individual at risk of poor health outcomes, and was measured using objective screening tools. Primary outcomes of interest were death, nursing home admission, unplanned hospital admission, emergency department visits and serious adverse events. CGA was delivered by a team with specific gerontological training/expertise in the participant's home (domiciliary Comprehensive Geriatric Assessment (dCGA)) or other sites such as a general practice or community clinic (community Comprehensive Geriatric Assessment (cCGA)).
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted study characteristics (methods, participants, intervention, outcomes, notes) using standardised data collection forms adapted from the Cochrane Effective Practice and Organisation of Care (EPOC) data collection form. Two review authors independently assessed the risk of bias for each included study and used the GRADE approach to assess the certainty of evidence for outcomes of interest.
MAIN RESULTS
We included 21 studies involving 7893 participants across 10 countries and four continents. Regarding selection bias, 12/21 studies used random sequence generation, while 9/21 used allocation concealment. In terms of performance bias, none of the studies were able to blind participants and personnel due to the nature of the intervention, while 14/21 had a blinded outcome assessment. Eighteen studies were at low risk of attrition bias, and risk of reporting bias was low in 7/21 studies. Fourteen studies were at low risk of bias in terms of differences of baseline characteristics. Three studies were at low risk of bias across all domains (accepting that it was not possible to blind participants and personnel to the intervention). CGA probably leads to little or no difference in mortality during a median follow-up of 12 months (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.76 to 1.02; 18 studies, 7151 participants (adjusted for clustering); moderate-certainty evidence). CGA results in little or no difference in nursing home admissions during a median follow-up of 12 months (RR 0.93, 95% CI 0.76 to 1.14; 13 studies, 4206 participants (adjusted for clustering); high-certainty evidence). CGA may decrease the risk of unplanned hospital admissions during a median follow-up of 14 months (RR 0.83, 95% CI 0.70 to 0.99; 6 studies, 1716 participants (adjusted for clustering); low-certainty evidence). The effect of CGA on emergency department visits is uncertain and evidence was very low certainty (RR 0.65, 95% CI 0.26 to 1.59; 3 studies, 873 participants (adjusted for clustering)). Only two studies (1380 participants; adjusted for clustering) reported serious adverse events (falls) with no impact on the risk; however, evidence was very low certainty (RR 0.82, 95% CI 0.58 to 1.17).
AUTHORS' CONCLUSIONS
CGA had no impact on death or nursing home admission. There is low-certainty evidence that community-dwelling, frail, older people who undergo CGA may have a reduced risk of unplanned hospital admission. Further studies examining the effect of CGA on emergency department visits and change in function and quality of life using standardised assessments are required.

Review
Acute kidney injury (AKI) is a common syndrome that is independently associated with increased mortality. A standardized definition is important to facilitate clinical care and research. The definition of AKI has evolved rapidly since 2004, with the introduction of the Risk, Injury, Failure, Loss, and End-stage renal disease (RIFLE), AKI Network (AKIN), and Kidney Disease Improving Global Outcomes (KDIGO) classifications. RIFLE was modified for pediatric use (pRIFLE). They were developed using both evidence and consensus. Small rises in serum creatinine are independently associated with increased mortality, and hence are incorporated into the current definition of AKI. The recent definition from the international KDIGO guideline merged RIFLE and AKIN. Systematic review has found that these definitions do not differ significantly in their performance. Health-care staff caring for children or adults should use standard criteria for AKI, such as the pRIFLE or KDIGO definitions, respectively. These efforts to standardize AKI definition are a substantial advance, although areas of uncertainty remain. The new definitions have enabled the use of electronic alerts to warn clinicians of possible AKI. Novel biomarkers may further refine the definition of AKI, but their use will need to produce tangible improvements in outcomes and cost effectiveness. Further developments in AKI definitions should be informed by research into their practical application across health-care providers. This review will discuss the definition of AKI and its use in practice for clinicians and laboratory scientists.

Meta-Analysis Review
OBJECTIVE
Preexposure prophylaxis (PrEP) offers a promising new approach to HIV prevention. This systematic review and meta-analysis evaluated the evidence for use of oral PrEP containing tenofovir disoproxil fumarate as an additional HIV prevention strategy in populations at substantial risk for HIV based on HIV acquisition, adverse events, drug resistance, sexual behavior, and reproductive health outcomes.
DESIGN
Rigorous systematic review and meta-analysis.
METHODS
A comprehensive search strategy reviewed three electronic databases and conference abstracts through April 2015. Pooled effect estimates were calculated using random-effects meta-analysis.
RESULTS
Eighteen studies were included, comprising data from 39 articles and six conference abstracts. Across populations and PrEP regimens, PrEP significantly reduced the risk of HIV acquisition compared with placebo. Trials with PrEP use more than 70% demonstrated the highest PrEP effectiveness (risk ratio = 0.30, 95% confidence interval: 0.21-0.45, P < 0.001) compared with placebo. Trials with low PrEP use did not show a significantly protective effect. Adverse events were similar between PrEP and placebo groups. More cases of drug-resistant HIV infection were found among PrEP users who initiated PrEP while acutely HIV-infected, but incidence of acquiring drug-resistant HIV during PrEP use was low. Studies consistently found no association between PrEP use and changes in sexual risk behavior. PrEP was not associated with increased pregnancy-related adverse events or hormonal contraception effectiveness.
CONCLUSION
PrEP is protective against HIV infection across populations, presents few significant safety risks, and there is no evidence of behavioral risk compensation. The effective and cost-effective use of PrEP will require development of best practices for fostering uptake and adherence among people at substantial HIV risk.

Review
BACKGROUND
Crush syndrome (CS) is a kind of traumatic and ischemic injury that seriously threatens life after prolonged compression. It is characterized by systemic inflammatory reaction, myoglobinuria, hyperkalemia and acute kidney injury (AKI). Especially AKI, it is the leading cause of death from CS. There are various cell death forms in AKI, among which ferroptosis is a typical form of cell death. However, the role of ferroptosis has not been fully revealed in CS-AKI.
AIM OF REVIEW
This review aimed to summarize the evidence of ferroptosis in CS-AKI and its related molecular mechanism, discuss the therapeutic significance of ferroptosis in CS-AKI, and open up new ideas for the treatment of CS-AKI.
KEY SCIENTIFIC CONCEPTS OF REVIEW
One of the main pathological manifestations of CS-AKI is renal tubular epithelial cell dysfunction and cell death, which has been attributed to massive deposition of myoglobin. Large amounts of myoglobin released from damaged muscle deposited in the renal tubules, impeding the normal renal tubules function and directly damaging the tubules with oxidative stress and elevated iron levels. Lipid peroxidation damage and iron overload are the distinguishing features of ferroptosis. Moreover, high levels of pro-inflammatory cytokines and damage-associated molecule pattern molecules (HMGB1, double-strand DNA, and macrophage extracellular trap) in renal tissue have been shown to promote ferroptosis. However, how ferroptosis occurs in CS-AKI and whether it can be a therapeutic target remains unclear. In our current work, we systematically reviewed the occurrence and underlying mechanism of ferroptosis in CS-AKI.

Review
AIMS AND OBJECTIVES
The objective of the study was to compare the safety and efficacy of etomidate and ketamine as induction agents for rapid sequence intubation (RSI) in acutely ill patients in emergency department and prehospital settings with respect to post-induction hypotension and first-pass intubation success during RSI.
MATERIALS AND METHODS
For this systematic review and meta-analysis, we searched PubMed, Embase, Cochrane, and ClinicalTrials.gov between database inception and June 1, 2021. Articles were included if they compared safety and efficacy of etomidate vs ketamine as induction agents, in patients undergoing RSI in emergency department and prehospital settings, without any restrictions on study design. The outcome measures were incidence of post-induction hypotension and first-pass intubation success. The dichotomous outcomes were assessed for odds ratio (OR) with 95% confidence interval (CI) using random-effects meta-analysis.
RESULTS
Of 87 records identified, 9 were eligible, all assessed as having a low to moderate risk of overall bias. Six studies, including 12,060 patients from prehospital emergency medical services, air medical transport, and emergency department settings, compared post-induction hypotension incidence between etomidate and ketamine groups. The meta-analysis showed that etomidate was associated with decreased risk of post-induction hypotension compared to ketamine (OR: 0.53; 95% CI: 0.31-0.91; = 68%). Seven studies, including 15,574 patients, reported on the rate of first-pass intubation success with etomidate vs ketamine. In the pooled analysis, no differences were seen in first-pass intubation success during RSI using etomidate vs ketamine as the induction agent (OR: 1.13; 95% CI: 0.95-1.36; = 16%).
CONCLUSION
The use of etomidate for induction during RSI is associated with a decreased risk of post-induction hypotension as compared to the use of ketamine, without an impact on the first-pass intubation success rate.

OBJECTIVE
A current assessment of case reports of possible drug-induced pancreatitis is needed. We systematically reviewed the case report literature to identify drugs with potential associations with acute pancreatitis and the burden of evidence supporting these associations.
METHODS
A protocol was developed a priori (PROSPERO CRD42017060473). We searched MEDLINE, Embase, the Cochrane Library, and additional sources to identify cases of drug-induced pancreatitis that met accepted diagnostic criteria of acute pancreatitis. Cases caused by multiple drugs or combination therapy were excluded. Established systematic review methods were used for screening and data extraction. A classification system for associated drugs was developed a priori based upon the number of cases, re-challenge, exclusion of non-drug causes of acute pancreatitis, and consistency of latency.
RESULTS
Seven-hundred and thirteen cases of potential drug-induced pancreatitis were identified, implicating 213 unique drugs. The evidence base was poor: exclusion of non-drug causes of acute pancreatitis was incomplete or poorly reported in all cases, 47% had at least one underlying condition predisposing to acute pancreatitis, and causality assessment was not conducted in 81%. Forty-five drugs (21%) were classified as having the highest level of evidence regarding their association with acute pancreatitis; causality was deemed to be probable or definite for 19 of these drugs (42%). Fifty-seven drugs (27%) had the lowest level of evidence regarding an association with acute pancreatitis, being implicated in single case reports, without exclusion of other causes of acute pancreatitis.
DISCUSSION
Much of the case report evidence upon which drug-induced pancreatitis associations are based is tenuous. A greater emphasis on exclusion of all non-drug causes of acute pancreatitis and on quality reporting would improve the evidence base. It should be recognized that reviews of case reports, are valuable scoping tools but have limited strength to establish drug-induced pancreatitis associations.
