RESUMO
Clear communication is paramount for achieving the safest and best patient outcomes, for maximising time efficiency, and lowering clinician workload. Multiple factors contribute to communication efficacy, including knowledge of topics between those communicating, interpersonal familiarity, and available time. Information exchange is growing faster and more frequent due to evolving communication technology, and communication is expanding as a response to increasing workloads. The number of referrals between specialties and the general practitioner (GP) is rising. The use of abbreviations has expanded in clinical communications and is likely to lead to misunderstanding, increased workload, and worse patient outcomes. In this article, we explore the use of abbreviations in the clinical setting.

Surgical and minimally-invasive procedures, including cardiac and radiological, have high-stake patient outcomes. Working pressures, altering shift rotas, and ever-increasing demands have led to worsening sleep patterns for surgeons and allied professionals. Sleep deprivation alone has harmful consequences in relation to clinical outcomes and the physical and mental health of the surgeon, and to offset fatigue, some surgeons use legal stimulants such as caffeine and energy drinks. This stimulant use, however, may come at the cost of negative effects on cognitive and physical function. We aimed to explore evidence behind the use of caffeine, and its consequences on technical performance and clinical outcomes.

We report on an additional innervation to the sternothyroid that, to our knowledge, has not been previously described. During a cadaveric neck dissection, we found an aberrant nerve to the sternothyroid in addition to the normal innervation. The classical innervation to the sternothyroid is through the ansa cervicalis (C1-C3), and the sternothyroid muscle is important for depression of the thyroid cartilage that is involved with swallowing and speech. The cervical plexus is difficult and time consuming to elucidate in fixed cadavers, which limits knowledge of variations from this source. Branches of the plexus are delicate and can be damaged during operations on the neck. Awareness of variations in innervation during operation reduces the chance of damage to nerves and prevents functional changes postoperatively.

A national approach to addressing sexually transmitted and blood-borne infections (STBBIs) was recently articulated in the Public Health Agency of Canada's new A Pan-Canadian Framework for Action: Reducing the health impact of sexually transmitted and blood-borne infections in Canada by 2030. This Framework promotes an integrated approach, with a focus on the key populations that are affected by overlapping epidemics (i.e., syndemics). We advance the idea that integrating surveillance would be helpful in characterizing and understanding the populations, locations, risk behaviours and other drivers that contribute to STBBI syndemics. The creation of matched or linked data systems that would allow routine reporting of integrated data is challenged by the technical barriers of integrating data silos as well as by the privacy and ethical considerations of merging sensitive individual-level data. Lessons can be learned from jurisdictions where an improved understanding of syndemics, through integrated STBBI surveillance, has led to more efficient and effective operational, program and policy decisions. Emerging enablers include the development of data standards and guidelines, investment in resources to overcome technical challenges and community engagement to support the ethical and non-stigmatizing use of integrated data. The Framework's call to action offers an opportunity for national discussion on priorities and resources needed to advance STBBI syndemic surveillance for local, regional and national reporting in Canada.
RESUMO
Several branches of the facial nerve are known to anastomose with branches of the cervical plexus, other cranial nerves, and the trigeminal nerve. Communication between the sensory transverse cervical nerve (C2, 3) and marginal mandibular nerve is, however, less well known, and in a previous study of 86 neck dissections we reported a 2.3% incidence of anastomoses between them. In this prospective study, we meticulously searched for more examples using both formalin-fixed cadavers and neck dissections. A total of 102 necks were included (both sides of 36 cadavers (n=72 necks), and 30 patients who had neck dissection for the management of squamous cell carcinoma). We found communications between these nerves on one side of a cadaver and in one neck dissection. When combined with the numbers from our previous study, the overall incidence was 2.1% in 188 necks. The marginal mandibular nerve was inseparable from the anastomosis with the transverse cervical nerve, and the variant should not be forgotten if we are to reduce the chance of postoperative weakness of the lower lip, particularly when operative exposure is more limited (such as during removal of the submandibular gland).

As clinicians, we sometimes fail to look after ourselves properly and do not regularly eat healthy foods or drink enough. Sleep is another factor that we often neglect. A lack of it can compromise our personal health and performance at work, and the "sleep debt" that results when this is chronic can take far longer to recover from than one might think. Now that junior doctors work more shift rotas and senior colleagues have onerous on-call responsibilities, we all need to be aware of the effects of sleep deprivation, which can lower the mood and motivation, weaken leadership, and result in more clinical errors. In this review we consider what might constitute enough sleep, the consequences of inadequate sleep, and how these might be addressed for surgeons.

Workplace-related illness is common in the UK, and in healthcare more than five million working days over 10years have been lost as a result. Occupational stress is well known and can affect clinicians at any stage, yet many healthcare professionals continue to work with this or other psychological problems (including anxiety, chronic fatigue, and burnout) as they do not wish to let their colleagues down. Mental health issues might be dismissed, particularly in surgery, because there is a misconception that surgeons can cope better with stress than those working in other specialties, and are better protected from clinical burnout. The benefit of exercise on physical health is clear, but its role in the maintenance of good mental health and well-being should not be underestimated. As society adopts an increasingly sedentary lifestyle, exercise for many has a lower priority than other activities. In this article we give an overview of the mental health issues that might affect doctors and surgeons, and explore how exercise can benefit our well-being and clinical performance.

Many people use dietary supplements to improve their physical and mental well-being and their general health, but do not know if they really have any benefit. To our knowledge, little has been published on their use in the clinical environment, so we evaluated the evidence for their benefits in people whose work is physically and mentally challenging. Studies on nutrition and supplementation in athletes and military personnel have clearly shown that several compounds improve cognition, mental well-being, and physical performance. Based on this evidence, and with the many pressures faced by healthcare workers, as well as the need for concentration and endurance, some dietary supplements might be beneficial. Supplementation of a balanced diet with omega-3 fatty acids, vitamin B3, vitamin C and associated antioxidants, vitamin D, and protein, may improve a clinician's physical and mental health and their performance at work. Specific research is, however, needed to evaluate this more fully.

As clinicians we sometimes fail to look after ourselves at work. We often do not drink enough during the day or miss lunch breaks while caring for patients, and this can be particularly evident during an all-day operating list when procedures are long and complex. Some operating theatre staff do not even eat breakfast regularly. Inadequate intake of fluids or nutrition can impair performance, lead to tiredness and headaches, and may compromise both our own health and the care we provide to patients. Other high-risk organisations, including aviation, have recognised that employees must look after themselves if they are to optimise their performance. In this review, we discuss the importance of adequate hydration and nutrition at work to raise awareness that this is essential if we are to provide the best care for our patients.

A thorough understanding of the role of human factors in error in health care for improving patient safely is paramount. One area particularly crucial for optimising clinical performance is the recognising the importance of situational awareness. Loss of situation awareness can occur in many different settings, particularly during stressful and unexpected situations. Tunnel vision is a classic example where clinicians focus on one aspect of care, often to the detriment of overall patient management. Loss of situational awareness can result in serious compromise to patient safety if it is not recognised by either the individual or clinical team. We provide an introduction to situational awareness for those not familiar with it, including some important theory which explains how awareness can be lost, and discuss the important approaches we use in our day-to-day practice to safeguard both patients and clinicians in the workplace environment.

The trainability of youths and the existence of periods of accelerated adaptation to training have become key subjects of debate in exercise science. The purpose of this meta-analysis was to characterise youth athletes' adaptability to sprint training across PRE-, MID-, and POST-peak height velocity (PHV) groups. Effect sizes were calculated as a measure of straight-line sprinting performance with studies qualifying based on the following criteria: (a) healthy male athletes who were engaged in organised sports; (b) groups of participants with a mean age between 10 and 18 years; (c) sprint training intervention duration between 4 and 16 weeks. Standardised mean differences showed sprint training to be moderately effective (Effect size=1.01, 95% confidence interval: 0.43-1.59) with adaptive responses being of large and moderate magnitude in the POST- (ES=1.39; 0.32-2.46) and MID- (ES=1.15; 0.40-1.9) PHV groups respectively. A negative effect size was found in the PRE group (ES=-0.18; -1.35-0.99). Youth training practitioners should prescribe sprint training modalities based on biological maturation status. Twice weekly training sessions should comprise up to 16 sprints of around 20 m with a work-to-rest ratio of 1:25 or greater than 90 s.

Few studies have investigated whether relative age effects (RAEs) exist in school sport. None have sought to test the competing maturational and social-agent hypotheses proposed to explain the RAE. We aimed to determine the presence of RAEs in multiple school sports and examine the contribution of maturational and social factors in commonplace school sports. We analyzed birth dates of n=10645 competitors (11-18 years) in the 2013 London Youth Games annual inter-school multisport competition and calculated odds ratio (OR) for students competing based on their yearly birth quarter (Q1-Q4). Multivariate logistic regression was used to determine the relative contribution of constituent year (Grade) and relative age in netball and football which used multiyear age groupings. In girls, RAEs were present in the team sports including hockey, netball, rugby union, cricket and volleyball but not football. In boys, RAEs were stronger in common team sports (football, basketball cricket) as well as athletics and rowing. In netball and football teams with players from two constituent years, birth quarter better-predicted selection than did constituent year. Relatively older players (Q1) from lower constituent years were overrepresented compared with players from Q3 and Q4 of the upper constituent years. RAEs are present in the many sports commonplace in English schools. Selection of relatively older players ahead of chronologically older students born later in the selection year suggests social agents contribute to RAEs in school sports.

The anatomical relation between the spinal accessory nerve and internal jugular vein is well documented, but other variants of the nerve, including the contributions of the cervical plexus to supply motor fibres to the trapezius, are less well known. We have previously described an anatomical variant in which the spinal accessory nerve divided before entering the sternocleidomastoid, and the inferior trunk passed directly under it to supply the trapezius. We now present a prospective study of 133 neck dissections (excluding radical dissections) in which a meticulous search was made for the variant in the anterior triangle of the neck during operation. We found it in 3 necks (2%). One of the 3 patients had a bilateral neck dissection but it was found on one side only, and in 2 cases it communicated with the cervical plexus. In all 3, stimulation of the inferior division resulted in contraction of the trapezius while the upper division was found to supply the sternocleidomastoid only. The finding of this variant, which was more common than first thought, highlights the need for meticulous dissection of the nerve before it enters the sternocleidomastoid to ensure that, when present, the inferior branch is preserved to minimise potential postoperative shoulder dysfunction. Further research including a cadaveric study is needed to understand this important variant more fully.

The aim of this study was to determine if month of birth affects performance in 3 tests of physical function in children and adolescents. We measured cardiorespiratory fitness, handgrip strength and lower-body power expressed them relative to (whole year) age then compared scores between calendar year birth-months. We also expressed test performance as the likelihood of achieving criterion-referenced fitness standards. There were significant main effects of birth-month for cardiorespiratory fitness (F=4.54, p<0.001), strength (F=6.81, p<0.001) and power (F=3.67, p<0.001). Children born in November were fitter and more powerful than those born at other times, particularly the summer months (April, May and June). October-born children were stronger than those born in all months except September and November. This relationship was evident despite controlling for decimal age and despite no significant inter-month differences in anthropometric characteristics.There is a clear physical advantage for those born in the autumn and this may explain some of the bias in sports selection attributed to the relative age effect, particularly when the British school-year (September) cut-off is used.

UNLABELLED: The purpose of this study was to use the Cognitive Anxiety Scale (CAS) to investigate relationships between state-anxiety level (cognitive anxiety) and audiometric variables in adults with hearing impairment at their initial consultation. Thirty-five adults with hearing impairment who consulted an audiologist for the first time participated in this study. An interview to obtain information about cognitive anxiety was conducted prior to the audiological assessment. The results indicated that cognitive anxiety was significantly related to an ability to understand speech in noise. Further, cognitive anxiety and ability to understand speech in noise significantly contributed to the classification of hearing aid adopters and non-adopters. These results indicate that the measure of cognitive anxiety may have clinical applications in the future. LEARNING OUTCOMES: The reader will be able to: (1) discuss the relationship between anxiety and hearing impairment; (2) define cognitive anxiety; (3) state the relationship between cognitive anxiety and audiometric variables; (4) state the relationship between cognitive anxiety and the decision to adopt hearing aids; (5) identify signs of cognitive anxiety in adults with hearing impairment.

The CRF (corticotropin-releasing factor) system is a key mediator of the stress response. Alterations in CRF signaling have been implicated in drug craving and ethanol consumption. The development of negative reinforcement via activation of brain stress systems has been proposed as a mechanism that contributes to alcohol dependence. Here, we isolated a gain-of-function allele of seb-3, a CRF receptor-like GPCR in Caenorhabditis elegans, providing an in vivo model of a constitutively activated stress system. We also characterized a loss-of-function allele of seb-3 and showed that SEB-3 positively regulates a stress response that leads to an enhanced active state of locomotion, behavioral arousal and tremor. SEB-3 also contributed to acute tolerance to ethanol and to the development of tremor during ethanol withdrawal. Furthermore, we found that a specific CRF(1) receptor antagonist reduced acute functional tolerance to ethanol in mice. These findings demonstrate functional conservation of the CRF system in responses to stress and ethanol in vertebrates and invertebrates.

BACKGROUND: Task analysis is a valuable research method for better understanding the activity of anaesthetists in the operating room (OR), providing evidence for designing and evaluating improvements to systems and processes. It may also assist in identifying potential error paths to adverse events, ultimately improving patient safety. Human observers are the current 'gold standard' for capturing task data, but they are expensive and have cognitive limitations. OBJECTIVES: Towards Automated Detection of Anaesthetic Activity (TADAA)--aims to produce an automated task analysis system, employing Radio Frequency Identification (RFID) technology to capture anaesthetists' location, orientation and stance (LOS). This is the first stage in a scheme for automatic detection of activity. METHODS: Active RFID tags were attached to anaesthetists and various objects in a high fidelity OR simulator, and anesthetic procedures performed. The anaesthetists' LOSs were calculated using received signal strength (RSS) measurements combined with machine learning tools including Self-Organizing Maps (SOMs). These LOSs were compared to those derived from video recordings. RESULTS: SOM clustering was effective at determining anaesthetists' LOS from RSS data for each procedure. However cross-procedure comparison was less reliable,probably because of changes in the environment. CONCLUSIONS: Active RFID tags provide potentially useful information on LOS at a low cost and with minimal impact on the work environment. Machine learning techniques may be employed to handle the variable nature of RFID's radio signals. Work on mapping LOS data to activities will involve integration with other sensors and task analysis techniques.
