Pouring cold water on fake news - a qualitative review of misinformation related to burns first aid.

Health misinformation is pervasive on the internet and social media, and can have wide-ranging and devastating repercussions. Burn injuries are highly prevalent, especially in resource-poor countries with less rigorous health and safety regulations and reduced access to quality healthcare, and especially among the pediatric population who rely on caregivers to tend to their injuries. Correct first aid is crucial to improving burn outcomes and avoiding further complications. The aim of this study was to qualitatively assess the content of misinformation related to burns online. A literature search was conducted on PubMed using search terms 'burns' OR 'burn injury' OR 'burns trauma' OR 'major burns' AND 'first aid' AND 'conspiracy' OR 'disinformation' OR 'misinformation' OR 'fake news'. Combinations of these terms were searched via Google, YouTube, Facebook, Instagram, TikTok and PubMed. Key areas of misinformation included unfounded use of 'natural' remedies, injudicious use of antibiotics, omission of key steps of first aid, and errors in specific details of first aid. Clinicians should be aware of misinformation available online related to first aid for burns, be aware that patients presenting with burns may have caused further injury with insufficient first aid or inappropriate home remedies, and lead public health campaigns to educate on the initial emergency management of burns.

Radiographers' knowledge and attitudes toward dementia.

INTRODUCTION: Dementia is a syndrome associated with a decline in brain function, impacting how we speak, think, feel, and behave. Misunderstanding of dementia and how it affects patients and their carers is common. There is limited research on how radiographers provide adequate care to those with dementia. Radiographers with knowledge and positive attitudes can reduce stigma and fear, improving the quality of care. This study aimed to assess radiographers' knowledge and attitudes towards dementia. METHODS: A cohort of registered radiographers in Ireland participated in an online survey. Two pre-existing validated questionnaires: The Alzheimer's Disease Knowledge Scale (ADKS) and the Dementia Attitudes Scale (DAS), assessed radiographers' knowledge and attitudes towards dementia and people with dementia. Scores were compared across variables such as gender, age, grade, qualification, work setting, and the number of years qualified. RESULTS: A total of 123 radiographers responded. Knowledge scores did not significantly differ across demographic groups (p > 0.05). Total knowledge scores ranged from 60% to 100%. Total attitude scores ranged from 50% to 100%. Participants with a BSc, MSc, and other post-graduate degrees scored higher on the attitude scale than those with a diploma qualification (p = 0.027). Those with less than 20 years' experience scored higher than those with more. Knowledge had little correlation with attitude (r = 0.0522; p = 0.5667). CONCLUSION: Findings indicate variations in attitudes linked to age and experience, and some misconceptions can be observed across varying groups. Interventions to improve attitudes and raise awareness are needed. IMPLICATIONS FOR PRACTICE: There is a need for further research and education on dementia care in the imaging department. We have identified areas requiring further education.

Sociodemographic and attitudinal predictors of simultaneous and redundant multiple marker and cell-free DNA screening among women aged ⩾35 years.

OBJECTIVE: To identify characteristics associated with undergoing cell-free DNA (cfDNA) and multiple marker screening (MMS) simultaneously or redundantly (after receiving negative results from the first screening test) among women aged ⩾35 years. STUDY DESIGN: Participants presenting for prenatal testing completed a questionnaire that included measures of pregnancy worry and attitudes toward potential testing outcomes; data on prenatal test use was obtained via medical record review. We used multivariable logistic regression to identify factors associated with redundant or simultaneous screening. RESULTS: Among 164 participants, 69 (42.1%) had cfDNA redundantly (n=51) to, or simultaneously (n=18) with, MMS. Compared with the 46 MMS-negative women who did not undergo further testing, those who underwent redundant or simultaneous cfDNA/MMS screening were more likely to have annual family incomes >$150 000, to feel having a miscarriage would be worse than having an intellectually disabled child, to desire comprehensive testing for intellectual disability and to have more pregnancy worry. CONCLUSION: Providers who counsel patients on prenatal aneuploidy screening tests should explain the appropriate utilization of these screening tests to avoid unnecessary or minimally informative use of multiple tests.

Effectiveness of interferon-free therapy for the treatment of HCV-patients with compensated cirrhosis treated through the Irish early access program.

BACKGROUND: We investigated the real-world effectiveness of interferon-free regimens for the treatment of patients with compensated cirrhosis infected with hepatitis C virus (HCV). METHOD: Using the Irish national HCV treatment registry, the effectiveness and safety of interferon-free regimens for HCV-infected patients treated between April 2015 and August 2016, was determined. RESULTS: A SVR12 was achieved in 86% of subjects treated with sofosbuvir/ledipasvir ± ribavirin (SOF/LDV±RBV), 93% treated with paritaprevir, ombitasvir and ritonavir combined with dasabuvir ± ribavirin (3D±RBV) and 89% treated with sofosbuvir/daclatasvir ± ribavirin (SOF/DCV±RBV). The discontinuation rate was 5% and the on-treatment mortality rate was 1%. CONCLUSION: The availability of interferon-free regimens represents a significant breakthrough for the treatment of HCV infection. Treatments options, with high SVR12 rates, are now available for patients with compensated cirrhosis who were unsuitable for treatment with interferon-based regimens. Data obtained from studies conducted in real world practice provide robust information fundamental for input into future economic evaluations for agents used for the treatment of HCV infection.

Direct costs of interferon-based and interferon-free direct-acting antiviral regimens for the treatment of chronic hepatitis C infection.

Given the increasing budget impact of Hepatitis C virus (HCV) treatment, robust real-world cost data are essential for healthcare decision-makers to evaluate and understand the costs and benefits of these treatments. To determine the direct cost of treating HCV infection in a hospital-based ambulatory care setting in Ireland based on available data from the Irish national hepatitis C treatment registry. A microcosting study of the direct costs of patients with hepatitis C treated with interferon-based and interferon-free direct-acting antiviral regimens was conducted. Attendance at the outpatient clinic for clinical assessment, the quantity of resources used per patient, the medication prescribed and the identification and timing of staff involvement was measured and combined to establish a mean cost of treatment per patient and a cost per sustained virological response (SVR). One hundred and sixty-eight patients were included in the analysis; 119 treated with interferon-based direct-acting antiviral regimens and 47 treated with interferon-free regimens. The mean costs of treatment with the interferon-based regimens per patient were €38 286 (95% CI €35 305-€41 061). The cost per SVR was €62 457. The mean cost of treatment with interferon-free regimens per patient was €55 734 (95% CI €50 906-€60 880). The cost per SVR was €81 873. Real-world cost data provide valuable information to enhance reimbursement decisions. While the direct costs associated with hepatitis C treatment in Ireland are substantial, it is reasonable to expect that the mean cost of treatment and the cost per SVR will reduce as patients with less advanced disease are treated with interferon-free therapies.

Generic medicines and generic substitution: contrasting perspectives of stakeholders in Ireland.

BACKGROUND: The Health (Pricing and Supply of Medical Goods) Act 2013 passed into law in July 2013 and legislated for generic substitution in Ireland. The aim of the study was to ascertain the knowledge and perceptions of stakeholders i.e. patients, pharmacists and prescribers, of generic medicines and to generic substitution with the passing of legislation. METHODS: Three stakeholder specific questionnaires were developed to assess knowledge of and perceptions to generic medicines and generic substitution. Purposive samples of patients, prescribers and pharmacists were analysed. Descriptive quantitative and qualitative analyses were undertaken. RESULTS AND DISCUSSION: A total of 762 healthcare professionals and 353 patients were recruited. The study highlighted that over 84% of patients were familiar with generic medicines and are supportive of the concept of generic substitution. Approximately 74% of prescribers and 84% of pharmacists were supportive of generic substitution in most cases. The main areas of concern highlighted by the healthcare professionals that might impact on the successful implementation of the policy, were the issue of bioequivalence with generic medicines, the computer software systems used at present in general practitioner (GP) surgeries and the availability of branded generics. The findings from this study identify a high baseline rate of acceptance to generic medicines and generic substitution among patients, prescribers and pharmacists in the Irish setting. The concerns of the main stakeholders provide a valuable insight into the potential difficulties that may arise in its implementation, and the need for on-going reassurance and proactive dissemination of the impact of the generic substitution policy. CONCLUSION: The existing positive attitude to generic medicines and generic substitution among key stakeholders in Ireland to generic substitution, combined with appropriate support and collaboration should result in the desired increase in rates of prescribing, dispensing and use of generic medicines.

'Let Us Protect Our Future' a culturally congruent evidenced-based HIV/STD risk-reduction intervention for young South African adolescents.

One of the worst HIV/AIDS epidemics in the world is occurring in South Africa, where heterosexual exposure is the main mode of HIV transmission. Young people 15-24 years of age, particularly women, account for a large share of new infections. Accordingly, there is an urgent need for behavior-change interventions to reduce the incidence of HIV among adolescents in South Africa. However, there are few such interventions with proven efficacy for South African adolescents, especially young adolescents. A recent cluster-randomized controlled trial of the 'Let Us Protect Our Future!' HIV/STD risk-reduction intervention for Grade 6 South African adolescents (mean age = 12.4 years) found significant decreases in self-reported sexual risk behaviors compared with a control intervention. This article describes the intervention, the use of the social cognitive theory and the reasoned action approach to develop the intervention, how formative research informed its development and the acceptability of the intervention. Challenges in designing and implementing HIV/STD risk-reduction interventions for young adolescents in sub-Saharan Africa are discussed.

Comparison of disc diffusion and epsilometer (E-test) testing techniques to determine antimicrobial susceptibility of Campylobacter isolates of food and human clinical origin.

The antibiotic resistance profiles of 75 Campylobacter isolates of food and human clinical origin was determined by two agar diffusion susceptibility methods; disc diffusion and epsilometer-test (E-test). The most common therapeutic antimicrobials, erythromycin, ciprofloxacin and tetracycline were studied, along with chloramphenicol, ampicillin and naladixic acid. The resistance observed for each antimicrobial, as determined by both of methods, were statistically compared using Fisher two-tailed analysis. Of the six antimicrobials studied only two were shown to have statistically different patterns when resistance was compared by disc diffusion and E-test. The percentage of isolates resistant to clinically relevant antimicrobials using both techniques ranged from 6.6 to 21.3% for erythromycin, 25.3-26.6% for tetracycline and 33.3-36.0% for ciprofloxacin. The prevalence of multi-drug resistant (MDR) campylobacters (isolates resistant to 2 or more antimicrobials) for both disc diffusion and E-test was 44%. It can be concluded that, for four of the six antimicrobials assessed, antimicrobial resistance prevalences could be equally determined by either of the methods studied.

Characteristics of bisexually active men in the Seropositive Urban Mens' Study (SUMS).

Characteristics of bisexually-active men were compared with those of their homosexually-active counterparts in a study of HIV-seropositive men who have sex with men (MSM). Men who had had sex with women in the prior year were younger and more likely to be African American than those reporting sex only with men. They reported higher levels of internalised homophobia and less participation in the gay community. They tended to be recruited through friend referral rather than public sex environments or AIDS service organisations. However, they did not seek sex partners from different venues than other participants. Implications for HIV transmission risk-reduction interventions for this population are discussed.

Theory of planned behaviour predictors of intention to use condoms among Xhosa adolescents in South Africa.

HIV/AIDS is taking a heavy toll on South African youth. Reducing their risk for HIV requires an understanding of the determinants of their HIV risk behaviours that are amendable to intervention-induced change. This study draws upon the theory of planned behaviour to identify the modifiable determinants of the intention to use condoms among Xhosa-speaking South African adolescents. The participants were 390 Xhosa-speaking 6th grade students (mean age = 12.1 years) in public schools in the township of Mdantsane, South Africa who completed an anonymous questionnaire. Multiple regression revealed that attitude and perceived behavioural control were significantly related to the intention to use condoms, whereas subjective norm was not, controlling for sexual experience, gender, and language preference. Consistent with this were additional analyses using beliefs as predictors: Hedonistic behavioural beliefs and control beliefs about condom-use negotiation and technical skills predicted intention, whereas normative beliefs did not. The theory of planned behaviour may be a useful model of condom use among Xhosa-speaking South African adolescents. An emphasis on beliefs about the adverse effects of condom use on sexual enjoyment, the ability to negotiate condom use, and the ability to use condoms correctly might improve the efficacy of HIV/STD interventions for such adolescents.

A low-cost, sustainable intervention for drinking reduction in the HIV primary care setting.

Excess drinking poses multiple substantial health risks to HIV-infected individuals. However, no published intervention studies have focused on drinking reduction as the main outcome in HIV primary care patients. An intervention in this setting must place minimal demands on pressured staff and resources. This pilot study tested such an intervention, which consisted of brief Motivational Interviewing (MI) and HealthCall, an automated daily telephone self-monitoring system based on Interactive Voice Response (IVR), designed to extend and enhance the effects of brief MI. Thirty-one patients entered the study, received a 30-minute MI and were instructed in daily use of the IVR system. They received graphical feedback on their daily drinking from the HealthCall database after 30 days. A statistically significant decrease in drinking was found over time, both as reported in daily IVR calls (beta = - 0.01, se 0.01, p=.03) and in follow-up interviews (beta = - 0.04, se 0.12, p=.02) at 60 days. The proportion of daily calls made supported the feasibility of the intervention. The results indicate that HealthCall is acceptable to a disadvantaged HIV patient population, and preliminary data support the efficacy of this intervention in reducing harmful drinking among HIV primary care patients.

Antibiotic resistance of retail food and human Campylobacter isolates on the island of Ireland from 2001-2002.

The antimicrobial resistance profiles of Campylobacter isolates recovered from a range of retail food samples (n=374) and humans (n=314) to eight antimicrobial compounds were investigated. High levels of resistance in food C. jejuni isolates were observed for ceftiofur (58%), ampicillin (25%) and nalidixic acid (17%) with lower levels observed for streptomycin (7.9%) and chloramphenicol (8.3%). A total of 80% of human C. jejuni isolates were resistant to ceftiofur, while 17% showed resistance to ampicillin and nalidixic acid, 8.6% to streptomycin and 4.1% to chloramphenicol. Resistance to clinically relevant antimicrobials such as erythromycin, ciprofloxacin and tetracycline was 6.7, 12, and 15% respectively for all food isolates and was similar to corresponding resistance prevalences observed for human isolates, where 6.4, 12 and 13% respectively were found to be resistant. Comparisons of C. jejuni isolates in each location showed a high degree of similarity although some regional variations did exist. Comparison of total C. jejuni and C. coli populations showed minor differences, with C. jejuni isolates more resistant to ampicillin and ceftiofur. Multidrug resistance patterns showed some profiles common to human and clinical isolates.
