Kinematic, Kinetic, and Temporal Metrics Associated With Golf Proficiency.

ABSTRACT: McHugh, MP, O'Mahoney, CA, Orishimo, KF, Kremenic, IJ, and Nicholas, SJ. Kinematic, kinetic, and temporal metrics associated with golf proficiency. J Strength Cond Res 38(3): 599-606, 2024-The biomechanics of the golf swing have been studied extensively, but the literature is unclear on which metrics are indicative of proficiency. The purpose of this study was to determine which metrics identified golf proficiency. It was hypothesized that discrete kinematic, kinetic, and temporal metrics would vary depending on proficiency and that combinations of metrics from each category would explain specific proficiency metrics. Kinematic, kinetic, and temporal metrics and their sequencing were collected for shots performed with a driver in 33 male golfers categorized as proficient, average, or unskilled (based on a combination of handicap, ball velocity, and driving distance). Kinematic data were collected with high-speed motion analysis, and ground reaction forces (GRF) were collected from dual force plates. Proficient golfers had greater x-factor at ball impact and greater trunk deceleration before ball impact compared with average ( p < 0.05) and unskilled ( p < 0.01) golfers. Unskilled golfers had lower x-factor at the top of the back swing and lower peak x-factor, and they took longer to reach peak trunk velocity and peak lead foot GRF compared with average ( p < 0.05) and proficient ( p < 0.05) golfers. A combination of 2 kinematic metrics (x-factor at ball impact and peak pelvis velocity), 1 kinetic metric (peak lead foot GRF), and 2 timing metrics (the timing of peak trunk and arm velocity) explained 85% of the variability in ball velocity. The finding that x-factor at ball impact and trunk deceleration identified golf proficiency points to the potential for axial trunk rotation training to improve performance.

AFM Force Mapping Elucidates Pilus Deployment and Key Lifestyle-Dependent Surface Properties in Bdellovibrio bacteriovorus.

Bdellovibrio bacteriovorus is known for predation of a wide variety of Gram-negative bacteria, making it of interest as an alternative or supplement to chemical antibiotics. However, a fraction of B. bacteriovorus follows a nonpredatory, "host-independent" (HI) life cycle. In this study, live predatory and HI B. bacteriovorus were captured on a surface and examined, in buffer, by collecting force maps using atomic force microscopy (AFM). The approach curves obtained on HI cells are similar to those on other Gram-negative cells, with a short nonlinear region followed by a linear region. In contrast, the approach curves obtained on predatory cells have a large nonlinear region, reflecting the unusual flexibility of the predatory cell. As the AFM tip is retracted, it shows virtually no adhesion to predatory B. bacteriovorus but has multiple adhesion events on HI cells and the 200-500+ nm region immediately surrounding them. Measured pull-off forces, pull-off distances, and effective spring constants are consistent with the multiple stretching events of Type IV pili, both on and especially adjacent to the cells. Exposure of the HI B. bacteriovorus to a pH-neutral 10% cranberry juice solution, which contains type A proanthocyanidins that are known to interfere with the adhesion of multiple types of pili, results in a substantial reduction in adhesion. Type IV pili are required for successful predation by B. bacteriovorus, but pili used in the predation process are located at the non-flagellated pole of the cell and can retract when not in use. Such pili are rarely observed under the conditions of this study, where the predator has not encountered a prey cell. In contrast, HI cells appear to have many pili distributed on and around the whole cell, presumably ready to be utilized for a variety of HI cell activities including attachment to surfaces.

Importance of Transverse Plane Flexibility for Proficiency in Golf.

ABSTRACT: McHugh, MP, O'Mahoney, CA, Orishimo, KF, Kremenic, IJ, and Nicholas, SJ. Importance of transverse plane flexibility for proficiency in golf. J Strength Cond Res 36(2): e49-e54, 2022-The extent to which the flexibility requirements for golf proficiency vary between the planes of motion has not been examined. The purpose of this study was to compare flexibility between proficient and average golfers with the hypothesis that proficient golfers have greater transverse plane flexibility than average golfers, with no differences in the sagittal and frontal planes. Twenty-five male golfers were categorized as proficient (handicap ≤5, n = 13) or average (handicap 10-20, n = 12). Fourteen flexibility tests were performed (4 shoulder tests, 4 trunk tests, and 6 hip tests) with tests in all 3 planes of motion for each body segment. In addition, trunk motion, pelvic motion, and hip motion during the golf swing were assessed with high-speed motion analysis. Ball speed and shot distance were recorded with a golf simulator. Proficient golfers had significantly better flexibility than average golfers in the transverse plane (shoulder p = 0.021, trunk p = 0.003, and hip p < 0.0001), with no differences in the sagittal plane or frontal plane (plane of motion by golf proficiency p = 0.0001). Transverse plane hip flexibility accounted for 48% of the variability in ball speed (p < 0.0001) and 45% of the variability in total distance (p = 0.001). During the golf swing, proficient golfers had greater separation between the pelvis and the trunk (x-factor) than average golfers (p = 0.002). In conclusion, transverse plane flexibility in the trunk and hips is an important requirement for golf proficiency. Sagittal plane flexibility and frontal plane flexibility were unrelated to proficiency. Developing and maintaining trunk and hip rotation flexibility is important for optimizing performance.

Health-related behaviours of nurses and other healthcare professionals: A cross-sectional study using the Scottish Health Survey.

AIMS: To estimate the prevalence and co-occurrence of health-related behaviours among nurses in Scotland relative to other healthcare workers and those in non-healthcare occupations. DESIGN: Secondary analysis of nationally representative cross-sectional data, reported following STROBE guidelines. METHODS: Five rounds (2008-2012) of the Scottish Health Survey were aggregated to estimate the prevalence and co-occurrence of health-related behaviours (smoking, alcohol consumption, physical activity, fruit/vegetable intake). The weighted sample (n = 18,820) included 471 nurses (3%), 433 other healthcare professionals (2%), 813 unregistered care workers (4%), and 17,103 in non-healthcare occupations (91%). Logistic regression models compared the prevalence of specific health-related behaviours and principal component analysis assessed co-occurrence of health-related behaviours between occupational groups. RESULTS: Nurses reported significantly better health-related behaviours relative to the general working population for smoking, fruit/vegetable intake, and physical activity. No significant difference was found for alcohol consumption between occupational groups. Nurses reported lower levels of harmful co-occurring behaviours (tobacco smoking and alcohol consumption) and higher levels of preventive behaviours (physical activity and fruit/vegetable intake) compared with the general working population. Other healthcare professionals had the lowest level of harmful health behaviours and the highest level of preventive health behaviours. Health-related behaviours were poorest among unregistered care workers. CONCLUSION: Nurses' health-related behaviours were better than the general population but non-adherence to public health guidelines was concerning. IMPACT: Nurses play an important role in health promotion through patient advice and role-modelling effects. To maximise their impact, healthcare providers should prioritise increasing access to healthy food, alcohol awareness, and smoking cessation programmes.

Interventions for maintaining nasogastric feeding after stroke: An integrative review of effectiveness and acceptability.

AIMS AND OBJECTIVES: To investigate the effectiveness and acceptability of interventions for maintaining nasogastric tubes in adult stroke patients. BACKGROUND: Internationally, incidence of cerebral vascular disease continues to increase and stroke is the largest cause of complex disability in adults. Dysphagia is common following a stroke which necessitates feeding via a nasogastric tube. Nasogastric tubes are not well tolerated by stroke patients and may be frequently dislodged. Hence, interventions such as tape, the nasal bridle/loop or hand mittens may be used to maintain nasogastric tube position. However, evidence around the effectiveness and acceptability of these interventions has not been reviewed and synthesised. DESIGN: Integrative literature review. METHOD: Database searches in MEDLINE, PubMed, CINAHL, Scopus, Cochrane and EMBASE; manual reference list searches. RESULTS: Seven studies met the eligibility criteria and were included in the review. Evidence for the effectiveness of nasal bridle/loop and hand mittens to maintain nasogastric tube position in patients after a stroke is spare and methodologically poor, and especially limited around hand mittens use. There is insufficient evidence about the acceptability of both nasal bridle/loop and hand mittens among stroke patients. CONCLUSION: Current clinical practice is underpinned by assumptions around the acceptability of nasal bridle/loop and hand mittens to secure nasogastric tubes. This results in reliance on consensual judgement between professional, patients and their families to guide their use among individuals with dysphagia after stroke. Further research is required to assess the effectiveness of hand mittens and acceptability of both nasal bridle/loop and hand mittens among stroke patients to inform guideline development. RELEVANCE TO CLINICAL PRACTICE: Given the lack of evidence on the acceptability of hand mittens and nasal bridle/loop among stroke patients to inform evidence-based guidelines and protocols, healthcare professionals should reach consensus on their use by exercising clinical judgement and through consultation with patients (if possible) and their families.

Media Depictions of "Unacceptable" Workplace Violence Toward Nurses.

Violence and aggression toward nurses are global concerns. Despite repeated research on causal factors and widespread zero tolerance campaigns, rates of violence and aggression have not declined. Violence and aggression toward nurses can negatively affect their health and ultimately patient care. Media reporting of violence and aggression toward nurses might shape people's perceptions of the profession, perhaps impeding nurse recruitment and retention efforts in the face of global nursing shortages. The purpose of this study was to determine how print media in Scotland depicted reports of violence and aggression toward nurses. We used qualitative thematic analysis of newspaper articles and online news reporting of incidents of violence and aggression toward nurses between June 1, 2006 and May 31, 2016. Searches of Nexis and British Broadcasting Corporation (BBC) News Online databases returned 92 relevant newspaper articles. Standards for reporting qualitative research informed presentation of results. Key themes included blame (of perpetrator or senior management), helplessness (of nurses specifically or victimization), culture (social or organizational), and prevention and reduction measures. We concluded that media coverage of violence and aggression was overwhelmingly negative and reductionist. Normalization of violence and aggression was an accepted and acceptable part of the nursing role. We conclude with recommendations for policy and call for nurse leaders to challenge this culture of acceptability, especially to support recruitment and retention of nursing staff.

Nasogastric feeding for stroke patients: practice and education.

BACKGROUND AND AIMS: Dysphagia is common after stroke, so feeding through a nasogastric (NG) tube may be necessary. These tubes are frequently dislodged, causing interruption to feeding and hydration, and potential aspiration of feed or fluids into the lungs. Interventions to prevent this may include taping tubes to the face; the application of hand mittens or bandaging patients' hands; inserting the NG tube into the nostril on the stroke-affected side; and nasal bridles. The aims of this survey were to investigate the management of NG feeding for stroke patients, including current tube confirmation and securing techniques, and associated nurse education. This was part of a three-phased sequential mixed-methods study. This paper reports on the second quantitative phase. METHODS: A quantitative postal survey, based on initial qualitative findings, was sent to registered nurses (n=528) from the National Stroke Nurses Forum and Scottish Stroke Nurses Forum, in addition to registered nurses working on stroke units within the local health board. RESULTS: The overall response rate was 59% (n=314/528). Tape was the most commonly used method for securing tube position, followed by inserting the tube on the stroke-affected side. Hand mittens were used more frequently than the nasal bridle; bandaging hands was reported once. Taping was considered to be more acceptable and safer than hand mittens or the nasal bridle, but less effective. Training in inserting NG feeding tubes was received by 56% (n=176/314). Methods used for confirming tube position included aspiration and X-ray. Provision of training in confirmation techniques varied. CONCLUSIONS: This study shows that the management of NG feeding for dysphagic stroke patients requires standardisation, as does the education for nurses to ensure that this intervention is carried out safely, effectively and acceptably.

Wearable activity trackers for nurses' health: A qualitative acceptability study.

AIM: To assess the practical, social and ethical acceptability of the use of a POLAR® H7 chest-strap wearable device to influence health behaviours among pre-registered nurses. DESIGN: Qualitative acceptability study including a simulated test of use reported using COREQ guidelines. METHODS: Pre-registered nurses simulated nine nursing tasks while wearing the chest strap in a clinical simulation facility in a Scottish university in 2016. Focus groups and semi-structured interviews were conducted to assess technology acceptance with participants who did and did not participate in the simulated nursing tasks. Focus groups and interviews were transcribed and analysed thematically guided by a theoretical model of technology acceptance. RESULTS: Pre-registered nurses thought the use of chest-strap devices to monitor their own health in real-time was acceptable. However, participants shared that it was important that the use of technology was inclusive and supportive of nurses' health and cautioned against misuse of data from wearable devices for individual performance management or stigmatisation.

Effects of student-led drama on nursing students' attitudes to interprofessional working and nursing advocacy: A pre-test post-test educational intervention study.

BACKGROUND: Nursing educators need to equip students to work in interprofessional teams and advocate for patients in increasingly integrated health and social care settings. Drama-based education has been used in nursing to help students understand complex concepts and practices, including communication, empathy, and patient safety. However, few studies have evaluated drama-based education to promote understanding of interprofessional care and advocacy, and none have involved student-led drama where students create dramatic performances to support learning. OBJECTIVES: To examine the effects of student-led drama on student nurses' attitudes to interprofessional working and advocacy. DESIGN: Pre-test post-test educational intervention study. SETTINGS: Public university in Scotland. PARTICIPANTS: 400 undergraduate student nurses enrolled on a 15-week module focussed on health and social care integration and interprofessional working. METHODS: Students completed paper questionnaires at the start (n = 274, response rate: 80.1 %) and end (n = 175, 63.9 %) of the module. Outcome measures were the validated Attitudes Towards Healthcare Teams Scale (ATHCTS) and Protective Nursing Advocacy Scale (PNAS). Change in mean ATHCTS and PNAS scores were assessed using paired samples t-tests, with Cohen's d to estimate effect size. RESULTS: ATHCTS scores significantly increased from 3.87 to 4.19 (p < 0.001, d = 0.52). PNAS scores increased from 3.58 to 3.81 (p < 0.001, d = 0.79), with significant improvements in the 'acting as an advocate' (4.18 to 4.51, p < 0.001, d = 0.81) and 'environmental and educational influences' subscales (3.79 to 4.13, p < 0.001, d = 0.75). Statements focussed on promoting holistic, dignified care and enabling health professionals to be responsive to emotional and financial needs of patients, showed greatest change. CONCLUSIONS: Education based on plays created and performed by student nurses led to significant improvements in student nurses' attitudes towards interprofessional working and nursing advocacy. Student-led drama should be embedded in nursing curricula to enable students to understand the realities and complexities of health and social care integration and interprofessional working.

Competencies and standards in nurse education: The irresolvable tensions.

This paper explores the inherent contradiction between the purpose of nurse education - to produce critical thinking, autonomous and accountable future nurses - and the prescription of standards and competencies to realize this goal. Drawing on examples from the United Kingdom's Nursing and Midwifery Council's (NMC) 'Future Nurse' standards, we argue that standards and competencies offer little more than a veneer of protection to the public and that, fundamentally, educational approaches based on 'dot point' formulations are antithetical to conditions in which genuinely critical-thinking, autonomous and accountable practitioners can develop. The purpose of this paper is to raise debate about the hegemony of competencies and standards. For the sake of academic health and the future of the nursing profession, the ubiquity of competency-based education must be critiqued and challenged.

Investigating the contribution of community nurses to anticipatory care: a qualitative exploratory study.

AIMS: To investigate how one aspect of anticipatory care is understood and delivered in practice. 'Anticipatory care' in this context can be understood as proactive care, which is oriented towards prevention of adverse events. BACKGROUND: Scotland has identified the intention to move away from a preoccupation with acute care and invest in health improvement and anticipatory care. Community nurses are the key, yet little is known about how they understand and deliver anticipatory care. METHODS: A qualitative case study design using individual in-depth interviews (n=10), observation (n=9) and focus groups (n=5) was selected. Five focus group interviews were carried out with district nurses, practice nurses and health visitors. Subsequently, nine observation events took place, each focused on a single nurse/client encounter. Data were collected during 2008 and 2009 in one Community Health Partnership in Scotland. FINDINGS: Two approaches to anticipatory care emerged; these were influenced by participants' roles and responsibilities. Approach 1 derives from Government policy agenda and is focused on protocol-focused management of long-term illness. Approach 2 is synonymous with long-standing nursing activity focused on holistic care of individual patients. Both approaches are proactive in nature. CONCLUSIONS: There is scope to develop a more conceptually complex model of anticipatory care, building on this initial exploration, within which all aims, roles, practices and methods of evaluation can be located and clearly visible. This offers the potential to enable practitioners to interpret and apply policy--otherwise change may be limited and result in service gaps.

Strategies to promote nurses' health: A qualitative study with student nurses.

Developing strategies to support student nurses' health is a global priority for healthcare organisations and governments. This is because emerging international evidence indicates that improvements in student nurses' health are required to increase the longevity of careers and reduce the loss of time, skill and financial cost of sickness absence and workforce exit. However, we do not know what intervention strategies student nurses think would support their health. The study aim was to explore student nurses' views on factors that influence health-related behaviours and strategies that could improve health. Data were collected through participatory activities during focus groups with student nurses in Scotland. Analysis was theoretically informed and involved mapping to the Behaviour Change Wheel framework. Students identified several factors that influenced health-related behaviours. Four were ranked most important: knowledge, culture, time constraints, and stress. Strategies student nurses thought should be prioritised to improve nurses' health-related behaviours were: stimulating a health-promoting environment by reviewing shift work, improving workplace support, increasing staffing levels, subsidising and role-modelling of healthy food and exercise; and creating applied health-promoting curricula by integrating time and stress management training and lifestyle advice into nursing education. Educational and environmental interventions are needed to support student nurses' health.

Antibiotic Use in Poultry Production in Grenada.

OBJECTIVE: Research is often lacking in low-income countries to substantiate the regulation of antibiotics in poultry production. Nonregulation of antibiotics in food animal industries has implications for human health. This study was conducted to provide an understanding of farmers' knowledge, attitudes, and practices regarding the use of antibiotics in poultry production in Grenada. METHOD: A cross-sectional study was conducted in August-September, 2016, surveying 30 poultry farmers each having 500 or more chickens grown for commercial purposes. RESULTS: More than 1000 birds were kept on 18 (60.0%) farms. Antibiotics were used on the majority of farms (25, 83.3%). More than half of the respondents, 19 (63.3%), stated they were only somewhat aware of issues related to the use of antibiotics and the majority, 21 (70.0%), were also unable to define antimicrobial resistance. There was inconsistency in the farmers' knowledge about how and when to use antibiotics. There was also a high level of noncompliance with manufacturers' recommendations for use of antibiotics. The respondents were not aware of local programs to monitor antibiotic use or manage antibiotic resistance in the poultry industry. CONCLUSION: Generally, the farmers' knowledge and practices were inconsistent with recommendations by the World Health Organization for antibiotic stewardship. While low-income countries, such as Grenada, are challenged with the lack of resources to undertake research and implement responsive actions, this research highlights the need for some immediate measures of remedy, such as education of farmers and monitoring procurement and use of antibiotics, to reduce risk to public health.

Community knowledge, attitudes and behaviours about environmental tobacco smoke in homes and cars.

OBJECTIVE: to assess knowledge, attitudes and behaviours about environmental tobacco smoke (ETS) in cars and homes in Queensland. METHOD: 1,026 randomly selected Queensland residents (84% response) participated in a computer assisted telephone survey to assess knowledge, attitudes and behaviours about ETS in cars and homes; and attitudes towards restrictions on smoking in a range of contexts. RESULTS: Most respondents are aware of the negative health effects of ETS and have smoking bans in their cars (75.8%) and homes (76.8%), however bans are less prevalent for smokers (cars: 37.9%; homes: 51%; p=0.000). For cars/homes, most smokers who did not have smoking bans would not smoke at all around pregnant women (67.7%/53.7%); fewer would refrain for childrenor=2 years (p=0.000) compared to non-parent smokers. Most respondents support car/ home smoking bans for children

Obesity prevalence among healthcare professionals in England: a cross-sectional study using the Health Survey for England.

OBJECTIVE: To estimate obesity prevalence among healthcare professionals in England and compare prevalence with those working outside of the health services. DESIGN: Cross-sectional study based on data from 5 years (2008-2012) of the nationally representative Health Survey for England. SETTING: England. PARTICIPANTS: 20 103 adults aged 17-65 years indicating they were economically active at the time of survey classified into four occupational groups: nurses (n=422), other healthcare professionals (n=412), unregistered care workers (n=736) and individuals employed in non-health-related occupations (n=18 533). OUTCOME MEASURE: Prevalence of obesity defined as body mass index ≥30.0 with 95% CIs and weighted to reflect the population. RESULTS: Obesity prevalence was high across all occupational groups including: among nurses (25.1%, 95% CI 20.9% to 29.4%); other healthcare professionals (14.4%, 95% CI 11.0% to 17.8%); non-health-related occupations (23.5%, 95% CI 22.9% to 24.1%); and unregistered care workers who had the highest prevalence of obesity (31.9%, 95% CI 28.4% to 35.3%). A logistic regression model adjusted for sociodemographic composition and survey year indicated that, compared with nurses, the odds of being obese were significantly lower for other healthcare professionals (adjusted OR (aOR) 0.52, 95% CI 0.37 to 0.75) and higher for unregistered care workers (aOR 1.46, 95% CI 1.11 to 1.93). There was no significant difference in obesity prevalence between nurses and people working in non-health-related occupations (aOR 0.94, 95% CI 0.74 to 1.18). CONCLUSIONS: High obesity prevalence among nurses and unregistered care workers is concerning as it increases the risks of musculoskeletal conditions and mental health conditions that are the main causes of sickness absence in health services. Further research is required to better understand the reasons for high obesity prevalence among healthcare professionals in England to inform interventions to support individuals to achieve and maintain a healthy weight.
