We examined whether the alpha-band coherence between the T7-Fz (verbal analytical-motor planning) brain areas were related to superior performance in sports. We searched for related papers across eight databases: ProQuest Central, ProQuest Psychology Journals, PsycARTICLES, PsycINFO, SPORTDiscus, MEDLINE, Scopus, and Web of Science using relevant keywords (i.e., EEG AND sports AND coherence). Seven studies, with a total of 194 participants, met our inclusion criteria and were shortlisted for statistical analysis. We compared EEG coherence data for both within-subject and between-subject experimental designs. Our analysis revealed that athletes had lower coherence in the T7-Fz brain pathway for alpha- band activation (Hedges\' g = - 0.54; p = 0.03) when performing better. Theoretically, these results corroborate the notion that athletes become more \"neurally efficient\" as the verbal and motor areas of their brains function more independently, i.e., the neural efficiency hypothesis. Accordingly, athletes who can limit verbal interference are more likely to perform a sporting task successfully.

OBJECTIVE: The aim of this study was to determine how front-line health professionals identify and manage nonfatal strangulation events.
METHODS: Integrative review with narrative synthesis was conducted.
METHODS: A comprehensive database search was conducted in six electronic databases (CINAHL, Wed of Science, DISCOVER, SCOPUS, PubMed and Scholar) resulting in 49 potentially eligible full texts, reduced to 10 articles for inclusion after exclusion criteria were applied.
METHODS: An integrative review was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement guidelines. Data were extracted, and a narrative synthesis using Whittemore and Knafl (2005) framework was undertaken to determine how front-line health professionals identify and manage nonfatal strangulation events.
RESULTS: The findings identified three main themes: an overall failure by health professionals to recognize nonfatal strangulation, a failure to report the event and a failure to follow up on victims after the event. Stigma and predetermined beliefs around nonfatal strangulation, along with a lack of knowledge about signs and symptoms, were the salient features in the literature.
CONCLUSIONS: Lack of training and fear of not knowing what to do next are barriers to providing care to victims of strangulation. Failure to detect, manage and support victims will continue the cycle of harm through the long-term health effects of strangulation. Early detection and management of strangulation are essential to prevent health complications, particularly when the victims are exposed to such behaviours repeatedly.
CONCLUSIONS: This review appears to be the first to explore how health professionals identify and manage nonfatal strangulation. It identified the significant need for education and robust and consistent screening and discharge policies to assist health providers of services where victims of nonfatal strangulation attend.
UNASSIGNED: This review contains no patient or public contribution since it was examining health professionals\' knowledge of identifying nonfatal strangulation and the screening and assessment tools used in clinical practice.

Choking and aspiration pneumonia are a leading cause of preventable death for people in residential care in Australia. In Victoria, in 2018-2019, 59% of deaths of persons in residential care that were referred to the coroner were from aspiration pneumonia. In 2016-2017, in New South Wales, the leading cause of death in people with disability living in residential care was pneumonitis caused by solids and fluids in the lungs. Such deaths are closely linked with swallowing problems (dysphagia) and people with cognitive impairments and multiple health issues, including mental health issues, are most at risk. This commentary focuses on coronial inquests where coroners\' findings have identified dysphagia or aspiration pneumonia as a cause of death or a contributor to a person\'s death. It also includes a summary of the recommendations by coroners which highlight processes that should be implemented to improve the safety of people with dysphagia.

Several institutions propose responsive feeding (RF) as the caregivers\' relational standard when nurturing a child, from breast/formula feeding onwards. Previous systematic reviews (SRs) on caregivers\' feeding practices (CFPs) have included studies on populations from countries with different cultures, rates of malnutrition, and incomes, whereas this SR compares different CFPs only in healthy children (4-24 months) from industrialized countries. Clinical questions were about the influence of different CFPs on several important outcomes, namely growth, overweight/obesity, risk of choking, dental caries, type 2 diabetes (DM2), and hypertension. The literature review does not support any Baby Led Weaning\'s or Baby-Led Introduction to SolidS\' (BLISS) positive influence on children\'s weight-length gain, nor their preventive effect on future overweight/obesity. RF-CFPs can result in adequate weight gain and a lower incidence of overweight/obesity during the first two years of life, whereas restrictive styles and coercive styles, two kinds of non-RF in CF, can have a negative effect, favoring excess weight and lower weight, respectively. Choking risk: failure to supervise a child\'s meals by an adult represents the most important risk factor; no cause-effect relation between BLW/BLISS/RF/NRCF and choking could be found. Risks of DM2, hypertension, and caries: different CFPs cannot be considered as a risky or preventive factor for developing these conditions later in life.

UNASSIGNED: Dysphagia and choking are highly prevalent in adults with mental health conditions. However, there is scant research considering the personal experience of dysphagia for this population.
UNASSIGNED: To understand the evidence-base for strategies to involve the patient in recognition, assessment and treatment of mealtime difficulties.
UNASSIGNED: This integrative review synthesised the literature on the experience of dysphagia in patients with mental health conditions. Patient consultation led to co-designed search terms and eligibility criteria for a systematic search of five scientific databases following Prisma guidance. Quality assessment of the eligible studies and reflexive thematic analysis were completed.
UNASSIGNED: 31 studies were included for review. These included case reports, literature reviews and cross-sectional studies. Quality of evidence was weak and no intervention studies were identified. There was scant detail regarding the personal experience of dysphagia or choking. Themes identified related to biomedical perspectives, influencing factors presented without context, and decision-making led by clinicians.
UNASSIGNED: Guidance on mental healthcare calls attention to under-diagnosis of physical co-morbidities and advocates patient inclusion. However, the patient voice in this population is rarely described regarding dysphagia. Further inclusive research is indicated to explore the impact of dysphagia and choking, and implications for interventions and outcome measures.

This systematic review draws together evidence from the literature for the pathological, neurological, cognitive, psychological, and behavioural outcomes of non-fatal strangulation in domestic and sexual violence. A systematic search of PubMed, PsycINFO, CINHAL, Proquest, ASSIA, Web of Science, WestLaw, Open Grey, and Ethos was conducted, with no date limits set, to identify eligible studies. Thirty empirical, peer-reviewed studies were found which met the inclusion criteria. Pathological changes included arterial dissection and stroke. Neurological consequences included loss of consciousness, indicating at least mild acquired brain injury, seizures, motor and speech disorders, and paralysis. Psychological outcomes included PTSD, depression, suicidality, and dissociation. Cognitive and behavioural sequelae were described less frequently, but included memory loss, increased aggression, compliance, and lack of help-seeking. However, no studies used formal neuropsychological assessment: the majority were medical case studies or based on self-report. Furthermore, few authors were able to control for possible confounds, including other physical violence and existing psychosocial difficulties. There is therefore a need for further neuropsychological research, focusing on cognitive and behavioural outcomes, using standardized tools, and control groups where possible. This is urgent, given societal normalization of strangulation, and legal systems which often do not reflect the act\'s severity and its consequences.

To summarise in a systematic review the effectiveness of interventions to treat foreign body airway obstructions (FBAO).
We searched MEDLINE, EMBASE, and the Cochrane library from inception on 30th September 2019 for studies that described the effectiveness of interventions to treat FBAO in adults and children. We included randomised controlled trials, observational studies and case series (≥5 cases) that described evidence of benefit. For evidence of harm/complications, we included case reports. Two reviewers independently assessed study eligibility, extracted study data, and assessed risk of bias. Data are summarised in a narrative synthesis. The GRADE system is used to assess evidence certainty.
We included 69 publications, comprising three cross-sectional studies (557 patients); eight case series (755 patients), and 59 were case reports (64 patients). One paper was included as a case series and cross-sectional study. For all interventions and associated outcomes, evidence certainty was very low. Early removal of FBAO by bystanders was associated with improved neurological survival (odds ratio 6.0, 95% confidence interval 1.5 to 23.4). Identified evidence showed that key interventions (back blows, abdominal thrusts, chest thrusts/compressions, Magill forceps, manual removal of obstructions from the mouth, suction-based airway clearance devices) are effective in relieving FBAO. We identified reports of harm in relation to back blows, abdominal thrusts, chest thrusts/compressions, and blind finger sweeps.
Key interventions successfully relieve FBAO, but may be associated with important harms. Guidelines for FBAO management should balance the benefits and harms of interventions.

Despite an obstructed airway (choking) being a relatively preventable injury, it has a considerable mortality burden globally, with increasing incidence. Given new technologies in choking management, this systematic review aimed to assess current literature on the effectiveness of anti-choking suction devices at relieving obstructions.
Ovid MEDLINE, Embase, PubMed, The Cochrane Library, SCOPUS, Web of Science, CINAHL Plus and the English websites of the devices were searched on September 23, 2019. Studies were included if they reported the anti-choking devices\' dislodgment success rate (primary outcome) or associated adverse events (secondary outcome). Articles, conference abstracts or technical reports were included if peer reviewed. Certainty of evidence was assessed in accordance with GRADE.
Five studies satisfied the inclusion criteria for this review. Two studies (40%) reported findings of a single centre mannequin trial, one (20%) of a single centre cadaveric trial, and two (40%) were case series. Cohen\'s Kappa for the first and second round of screening was 0.904 and 0.674 respectively. Although several devices have been manufactured worldwide, the LifeVac© has been most extensively studied, with a combined dislodgement success rate of 94.3% on first attempt. However, certainty of evidence for the primary outcome was evaluated as very low.
There are many weaknesses in the available data and few unbiased trials that test the effectiveness of anti-choking suction devices resulting in insufficient evidence to support or discourage their use. Practitioners should continue to adhere to guidelines authored by local resuscitation authorities which align with ILCOR recommendations.

Non-fatal strangulation (NFS) can be a cause of severe injury. However, the prevalence and rates of injuries from NFS are unknown, as few victims present to medical attention after strangulation. As up to 40% of fatal strangulations have no external signs, and the majority of surviving victims have few or minor injuries, finding those people severely injured remains challenging. The majority of the evidence regarding NFS is largely based on case reports and case series with no robust studies estimating rates of injuries or the best investigation tools. The injuries that are reported make clear that strangulation is a potentially lethal form of injury that should not be ignored in those presenting having been strangled, or in those presenting with neurological symptoms, including strokes, seizures and vascular abnormalities. The safety implications of strangulation are also important as it can be a prelude to homicide. A search of the literature was carried out with the following terms: Nonfatal strangulation (10), Nonfatal strangulation (17), \'Strangulation injuries\' (19), \'Manual strangulation\' (92) - laboratory testing eliminated, and \'choking game\'. The PubMed database was used first, followed by the collections of Monash University and the Strangulation Institute (as some articles were too old to find electronically). This article summarises the injuries that can occur following strangulation and discusses the quality of the evidence thus far.

OBJECTIVE: To present a novel approach for the emergent, pre-hospital management of life-threatening aerodigestive tract foreign body aspiration using a portable, non-powered, suction-generating device (PNSD), in the context of a literature review of emergent pre-hospital management of patients with foreign body airway obstruction.
METHODS: The PubMed and MEDLINE databases were comprehensively screened using broad search terms. A literature review of pre-hospital management and resuscitative techniques of foreign body airway obstruction was performed. Further, independent measurements of PNSD pressure generation were obtained. Application of a PNSD in cadaveric and simulation models were reviewed. A comparative analysis between a PNSD and other resuscitative techniques was performed.
RESULTS: Physiologic data from adult and pediatric human, non-human, and simulation studies show pressure generation ranging from 5.4 to 179 cm H2O using well-established resuscitative maneuvers. Laboratory testing demonstrated that a protypic PNSD demonstrated peak airway pressures of 434.23 ± 12.35 cm H2O. A simulation study of a PNSD demonstrated 94% reliability in retrieving airway foreign body, while a similar cadaveric study demonstrated 98% reliability, with both studies approaching 100% success rate after multiple attempts. Several case reports have also shown successful application of PNSD in the emergent management of airway foreign body in elderly and disabled patients.
CONCLUSIONS: PNSDs may play an important role in the emergent, non-operative, pre-hospital management of upper aerodigestive tract foreign body aspiration, particularly in settings and populations with high choking risk. Further characterization of effectiveness and safety in larger cadaveric or simulation studies mimicking physiologic conditions is indicated.
