The role of insurance data in setting priorities for netball injury prevention strategies

The aim of this study was to investigate insurance records for a one-year period to determine the injury frequencies and costs associated with different age groups in netball. The insurance records for all netball claims made during 1999 in Victoria were obtained from the insurer and entered into a database. The overall injury rate was 9.49 injuries per 1000 players, with 829 claims for injuries filed with the insurance company. Of all injuries claimed for, 85.3% were to the lower limb, 8.7% to the upper limb, 3.1% to the spine/torso and 2.9% to the head and face. Lower limb injuries accounted for 85.4% of costs, upper limb injuries 10.7% and head/neck/torso injuries 3.9% of total injury costs. Knee injuries accounted for 56.9% of total costs, with ankle and calf/Achilles injuries costing 12.7 and 11.8% of total costs, respectively. Injury prevention strategies should therefore be directed to three main injuries taking into account costs and incidence. These injuries were: ankle sprains, knee ligament sprains and Achilles tendon strains. Specifically, the prevention program for Achilles injuries should be directed to the >25 years age groups.     

Personal protective equipment related skin reactions in healthcare professionals during COVID‐19

Since the outbreak of COVID‐19 pandemic, clinicians have had to use personal protective equipment (PPE) for prolonged periods. This has been associated with detrimental effects, especially in relation to the skin health. The present study describes a comprehensive survey of healthcare workers (HCWs) to describe their experiences using PPE in managing COVID‐19 patients, with a particular focus on adverse skin reactions. A 24‐hour prevalence study and multi‐centre prospective survey were designed to capture the impact of PPE on skin health of hospital staff. Questionnaires incorporated demographics of participants, PPE type, usage time, and removal frequency. Participants reported the nature and location of any corresponding adverse skin reactions. The prevalence study included all staff in intensive care from a single centre, while the prospective study used a convenience sample of staff from three acute care providers in the United Kingdom. A total of 108 staff were recruited into the prevalence study, while 307 HCWs from a variety of professional backgrounds and demographics participated in the prospective study. Various skin adverse reactions were reported for the prevalence study, with the bridge of the nose (69%) and ears (30%) being the most affected. Of the six adverse skin reactions recorded for the prospective study, the most common were redness blanching (33%), itchiness (22%), and pressure damage (12%). These occurred predominantly at the bridge of the nose and the ears. There were significant associations (P < .05) between the adverse skin reactions with both the average daily time of PPE usage and the frequency of PPE relief. The comprehensive study revealed that the use of PPE leads to an array of skin reactions at various facial locations of HCWs. Improvements in guidelines are required for PPE usage to protect skin health. In addition, modifications to PPE designs are required to accommodate a range of face shapes and appropriate materials to improve device safety.     

An endogenous A2B adenosine receptor coupled to cyclic AMP generation in human embryonic kidney (HEK 293) cells

1. Cyclic AMP generation by adenosine analogues was examined in human embryonic kidney (HEK 293) cells by use of a [³H]-adenine pre-labelling methodology.
2. Adenosine analogues showed the following rank order of potency (pD₂ value): 5′-N-ethylcarboxamidoadenosine (NECA, 5.24)>2-chloroadenosine (4.41) ⩾ adenosine (4.19)=N⁶-(2-(4-aminophenyl)-ethylamino)adenosine (APNEA, 4.11). The A_2A-selective agonist {"type":"entrez-protein","attrs":{"text":"CGS21680","term_id":"878113053","term_text":"CGS21680"}}CGS21680 failed to elicit a significant stimulation of cyclic AMP generation at concentrations below 30 μM.
3. Of these agents, NECA was observed to exhibit the greatest intrinsic activity, while in comparison maximal responses to adenosine (76±8% NECA response), 2-chloroadenosine (70±6%) and APNEA (40±3%) were significantly reduced.
4. Antagonists of the NECA-evoked cyclic AMP generation showed the rank order of apparent affinity (apparent pA₂ value): CGS 15943 (7.79)=XAC (7.74)>DPCPX (7.01)=PD115199 (6.93)=8FB-PTP (6.80)>KF 17837 (5.98)>3-propylxanthine (5.13).
5. Agarose gel electrophoresis of the products of the polymerase chain reaction, with cDNA generated from HEK 293 cell total RNA showed virtually identical patterns and nucleotide sizes in comparison with the vector for the full length human brain A_2B adenosine receptor.
6. We concluded that HEK 293 cells express an endogenous adenosine receptor coupled to cyclic AMP generation which is of the A_2B subtype.

     

Crack and cocaine use among female prostitutes in Glasgow: Risky business

The experience of cocaine and 'crack' use among participants involved in (n = 19) or exiting (n = 10) prostitution in Glasgow, Scotland, is described. In-depth semi-structured qualitative interviews enquired about their use and experience of using cocaine and their perception of its effect on working practice. Twenty-three of 29 participants had used cocaine and 15 out of 29 had used crack cocaine. In reality, freebase not 'crack' was being self-manufactured from cocaine powder. Participants considered that cocaine use in the city was not restricted to prostitution but was reflected throughout the drug scene generally. One possible reason suggested for this was a perceived reduction in heroin availability at a time when cocaine was increasingly readily available. There was no evidence from participants to suggest that they were first introduced to cocaine through prostitution. Most participants believed that using cocaine did not affect how they worked, however they perceived that other prostitutes were prepared to take more risks to support their cocaine use and had to work longer hours to finance a cocaine habit compared to financing a heroin habit. Only participants recruited from the east end of the city spoke about their desperation for money and the sexual risks that they were prepared to take to buy cocaine. Harm-reduction messages should address the sexual and personal risks that some female prostitutes may be taking to support their cocaine use. Treatment and support services in the city, traditionally established to work with problematic heroin users, need to adapt to the changing drug trends among female drug users, including those involved in prostitution, and offer appropriate treatment options and harm-reduction advice to cocaine users.     

A systematic narrative review of consumer‐directed care for older people: implications for model development

Consumer‐directed care is increasingly becoming a mainstream option in community‐based aged care. However, a systematic review describing how the current evaluation research translates into practise has not been published to date. This review aimed to systematically establish an evidence base of user preferences for and satisfaction with services associated with consumer‐directed care programmes for older people. Twelve databases were searched, including MedLine, BioMed Central, Cinahl, Expanded Academic ASAP, PsychInfo, ProQuest, Age Line, Science Direct, Social Citation Index, Sociological Abstracts, Web of Science and the Cochrane Library. Google Scholar and Google were also searched. Eligible studies were those reporting on choice, user preferences and service satisfaction outcomes regarding a programme or model of home‐based care in the United States or United Kingdom. This systematic narrative review retrieved literature published from January 1992 to August 2011. A total of 277 references were identified. Of these 17 met the selection criteria and were reviewed. Findings indicate that older people report varying preferences for consumer‐directed care with some demonstrating limited interest. Clients and carers reported good service satisfaction. However, research comparing user preferences across countries or investigating how ecological factors shape user preferences has received limited attention. Policy‐makers and practitioners need to carefully consider the diverse contexts, needs and preferences of older adults in adopting consumer‐directed care approaches in community aged care. The review calls for the development of consumer‐directed care programmes offering a broad range of options that allow for personalisation and greater control over services without necessarily transferring the responsibility for administrative responsibilities to service users. Review findings suggest that consumer‐directed care approaches have the potential to empower older people.
