Contact lens prescribing trends 2015 : The Efron, Morgan and Woods 16th annual survey of Australian contact lens prescribing habits

The 16th annual survey ofAustralian contact lens prescribingwas conducted from January toApril 2015. The same format as inprevious years was employed. Ane-mail was sent to all members ofOptometry Australia with a link to adownloadable questionnaire, and arequest that this be accessed, printedand completed to provide detailsof the first 10 patients fitted withcontact lenses after receipt of thequestionnaire.The survey was specifically designedto be straightforward to completewhile capturing key informationabout their patients. Practitionerswere asked general questions aboutthemselves. For each contact lensfitting, they were requested tocomplete the following details: dateof fitting, new fitting or refitting, ageand sex of patient, lens material, lensdesign, frequency of replacement,times per week of wear, modality(daily or extended wear) and caresystem. Practitioners were asked toreturn the questionnaire by fax, postor e-mail.Completed questionnaires relatingto 353 contact lens fittings werereturned, which provides a soundbasis for a meaningful analysis. Eachfitting was given a weighting based onthe number of lenses fitted per yearby the practitioner, based on the dateinformation on the form. This meansthat data generated by practitionerswho have a higher frequency of fittingcontact lenses were afforded a higherweighting than those taking longer tofit the 10 patients with lenses.This discussion concentratesprimarily on data relating to newlens fittings as opposed to refittings.We believe that new fittings are amore sensitive barometer of currentpatterns and future trends, whereasrefittings are more indicative ofprevious fitting behaviours.In keeping with other markets aroundthe world,1 the majority of lenses (62per cent) were fitted to females. Theaverage age of contact lens wearersat the time of fitting was 32.2 ± 16.5years. The age at fitting ranged fromeight to 75 years.

Western propaganda models reconsidered : the "Catherine Whell" of censorship circumvention in developing world internal conflicts

This study is a deep-text analysis of military censorship applied to the national press in the Sri Lankan conflict. We examine press coverage of two Sri Lankan military operations, namely Operation Jayasikurui (1997) and the Capture of Elephant Pass (2000), to identify patterns of signification that help us construct a novel theory of conflict reporting under censorship within the context of ethnic, intrastate conflict. Our study shows that Sri Lankan newspapers, while abiding by censorship regulations, contradictorily also manoeuvred around these regulations as if censorship did not exist. Noteworthy were the censorship circumvention techniques that were used. For example, journalists taught readers how to ‘read’ blank space. They used commentary to educate readers how to read the straight news. They used conflict frames to overcome bias towards official viewpoints. They used multi-source confirmation to avoid pre-dominance of official views. They used respectful words rather than demonised opponents. Great attention
was paid to victims of the conflict, destruction of life and property, and civil society. Our findings do not accord well with previous theoretical models of the media role in society and of press censorship under conflict. The Sri Lankan press is highly intertwined within its cultural context and follows its own value system. We propose the ‘Catherine Wheel Model of Censorship Circumvention’ about press behaviour in times of internal conflict. Our model attempts to explain internal conflict within the developing world context in which the press system is based deeply in culture and is more accustomed to circumventing censorship than obeying it.

Ethics is a broad discipline and in health the debate between bioethics and behavioural ethics is one that goes to the centre of public health debates.

Diet and sleep in children with attention deficit hyperactivity disorder : Preliminary data in Australian children

Sleep disturbances are common and consequential in children with attention deficit hyperactivity disorder (ADHD). Diet also influences ADHD symptoms. Interrelationships between diet, sleep and behaviour in children diagnosed with ADHD are little studied. We investigated, via parental report, the relationships between sleep and diet in 88 Australian children aged 6—13 years old (M = 8.94, SD = 1.78). This pilot data shows that 30 per cent of the children had sleep disturbance (≥ 2 standard deviations above the mean) with significant relationships between ADHD symptoms, sleep disturbance and diet. Parents who reported more sleep disturbance also reported a higher intake of carbohydrate, fats, and, most particularly, sugar which was also a significant predictor of night time sweating. These findings suggest an interrelationship between diet and sleep in children with ADHD. Given that both sleep and dietary intake are potentially modifiable behaviours within treatment regimes of children with ADHD, further investigation is needed.

Utilisation of general practitioner services and achievement of guideline targets by people with diabetes who joined a peer-support program in Victoria, Australia

This paper describes the use of general practitioner (GP) services and achievement of guideline targets by 285 adults with type 2 diabetes in urban and regional areas of Victoria, Australia. Anthropometric and biomedical measures and responses to a self-administered questionnaire were collected. Findings indicate that almost all participants had visited a GP and had had their hypoglycated haemoglobin (HbA1c) measured in the past 6 months; less than one-third had visited a practice nurse. Fifty per cent achieved a HbA1c target of ≤7.0%; 40%, a total cholesterol ≤4.00 mmol/L; 39%, BP Systolic ≤130 mmHg; 51%, BP Diastolic ≤80 mmHg; 15%, body mass index ≤25 kg/m2; and 34% reported a moderately intense level of physical activity, that is, ≥30 min, 5 days a week. However, 39% of individuals achieved at least two targets and 18% achieved at least three of these guideline targets. Regional participants were more likely to report having a management plan and having visited a practice nurse, but they were less likely to have visited other health professionals. Therefore, a more sustained effort that also includes collaborative care approaches is required to improve the management of diabetes in Australia.
