Association of author's financial conflict of interest with characteristics and outcome of rheumatoid arthritis randomized controlled trials.

OBJECTIVE: To examine the prevalence, types and temporal trends of reported financial conflicts of interest (FCOIs) among authors of drug therapy randomized controlled trials (RCTs) for RA and their association with study outcomes. METHODS: We identified original, non-phase 1, parallel-group, drug therapy RA RCTs published in the years 2002-03, 2006-07, and 2010-11. Two investigators independently obtained trial characteristics data. Authors' FCOIs were classified as honoraria/consultation fees receipt, employee status, research grant, and stock ownership. Multivariable logistic regression was performed to identify whether FCOIs were independently associated with study outcome. RESULTS: A total of 146 eligible RCTs were identified. Of these, 83 (58.4%) RCTs had at least one author with an FCOI [employee status: 63 (43.2%), honoraria/consultation fees receipt: 49 (33.6%), research grant: 30 (20.5%), and stock ownership: 28 (19.2%)]. A remarkable temporal increase in reporting of honoraria/consultation fees receipt, research grant, and stock ownership was seen. The reporting of any FCOI itself was not associated with positive outcome [50/73 (68.5%) with author FCOI vs 36/52 (69.2%) without author FCOI, P = 0.93]. However, honoraria/consulting fees receipt was independently associated with increased likelihood of a positive outcome [adjusted odds ratio (95% CI) of 3.24 (1.06-9.88)]. In general, trials with FCOIs were significantly more likely to be multicentre, have larger enrolment, use biologic or a small molecule as the experimental intervention, and have better reporting of some methodological quality measures. CONCLUSION: FCOI reporting in RA drug RCT authors is common and temporally increasing. Receipt of honoraria/consulting fees was independently associated with a positive study outcome.

Intercentre variance in patient reported outcomes is lower than objective rheumatoid arthritis activity measures: a cross-sectional study.

Objective: To assess intercentre variability in the ACR core set measures, DAS28 based on three variables (DAS28v3) and Routine Assessment of Patient Index Data 3 in a multinational study. Methods: Seven thousand and twenty-three patients were recruited (84 centres; 30 countries) using a standard protocol in the Quantitative Standard Monitoring of Patients with RA study. Analysis of variance (ANOVA) and mixed-effect analysis of covariance models were used to model the relationship between study centre and different patient-reported and physician-reported RA activity measures. These models were built to adjust for the remaining ACR core set measure (for each ACR core set measure or each composite index), socio-demographics and medical characteristics. ANOVA and analysis of covariance models yielded similar results, and ANOVA tables were used to present variance attributable to recruiting centre. Results: The proportion of variances attributable to recruiting centre was lower for patient reported outcomes (PROs: pain, HAQ, patient global) compared with objective measures (joint counts, ESR, physician global) in all models. In the full model, variance in PROs attributable to recruiting centre ranged from 1.53% for patient global to 3.71% for HAQ compared with objective measures that ranged from 5.92% for physician global to 9.25% for ESR; and was lower for Routine Assessment of Patient Index Data 3 (2.6%) compared with DAS28v3 (11.75%). Conclusion: Intercentre variability in PROs is lower than objective measures of RA activity demonstrating that PROs may be more comparable across centres, and the need for standardization of objective measures.

Smoking cessation advice by rheumatologists: results of an international survey.

OBJECTIVE: The aim of this study was to understand practices regarding smoking cessation among rheumatologists for patients with inflammatory rheumatic diseases. METHODS: A survey was sent to the rheumatologists participating in the multinational Quantitative Standard Monitoring of Patients with Rheumatoid Arthritis (QUEST-RA) group. The survey inquired about the clinical practice characteristics and practices regarding smoking cessation (proportion of smokers with inflammatory rheumatic diseases given smoking cessation advice, specific protocols and written advice material, availability of dedicated smoking cessation clinic). RESULTS: Rheumatologists from 44 departments in 25 countries (16 European) completed the survey. The survey involved 395 rheumatologists, of whom 25 (6.3%) were smokers, and 199 nurses for patient education, of whom 44 (22.1%) were smokers. Eight departments (18.1 %) had a specific protocol for smoking cessation; 255 (64.5%) rheumatologists reported giving smoking cessation advice to all or almost all smokers with inflammatory diseases. In a regression model, early arthritis clinics (P = 0.01) and high gross domestic product countries (P = 0.001) were both independently associated with advice by the rheumatologist. Nurse gives advice to most patients in 11 of the 36 (30.5%) departments with nurses for patient education. CONCLUSION: Advice for smoking cessation within rheumatology departments is not homogeneous. In half of the departments, most doctors give advice to quit smoking to all or almost all patients with inflammatory diseases. However, only one in five departments have a specific protocol for smoking cessation. Our data highlight the need to improve awareness of the importance of and better practice implementation of smoking cessation advice for inflammatory rheumatic disease patients.

The association of fatigue, comorbidity burden, disease activity, disability and gross domestic product in patients with rheumatoid arthritis. Results from 34 countries participating in the Quest-RA program.

OBJECTIVES: The aim is to assess the prevalence of comorbidities and to further analyse to which degree fatigue can be explained by comorbidity burden, disease activity, disability and gross domestic product (GDP) in patients with rheumatoid arthritis (RA). METHODS: Nine thousands eight hundred seventy-four patients from 34 countries, 16 with high GDP (>24.000 US dollars [USD] per capita) and 18 low-GDP countries (<24.000 USD) participated in the Quantitative Standard monitoring of Patients with RA (QUEST-RA) study. The prevalence of 31 comorbid conditions, fatigue (0-10 cm visual analogue scale [VAS] [10=worst]), disease activity in 28 joints (DAS28), and physical disability (Health Assessment Questionnaire score [HAQ]) were assessed. Univariate and multivariate linear regression analyses were performed to assess the association between fatigue and comorbidities, disease activity, disability and GDP. RESULTS: Overall, patients reported a median of 2 comorbid conditions of which hypertension (31.5%), osteoporosis (17.6%), osteoarthritis (15.5%) and hyperlipidaemia (14.2%) were the most prevalent. The majority of comorbidities were more common in high-GDP countries. The median fatigue score was 4.4 (4.8 in low-GDP countries and 3.8 in high-GDP countries, p<0.001). In low-GDP countries 25.4% of the patients had a high level of fatigue (>6.6) compared with 23.0% in high-GDP countries (p<0.001). In univariate analysis, fatigue increased with increasing number of comorbidities, disease activity and disability in both high- and low-GDP countries. In multivariate analysis of all countries, these 3 variables explained 29.4% of the variability, whereas GDP was not significant. CONCLUSIONS: Fatigue is a widespread problem associated with high comorbidity burden, disease activity and disability regardless of GDP.

Association of industry funding with the outcome and quality of randomized controlled trials of drug therapy for rheumatoid arthritis.

OBJECTIVE: To assess the association of industry funding with the characteristics, outcome, and reported quality of randomized controlled trials (RCTs) of drug therapy for rheumatoid arthritis (RA). METHODS: The Medline and Cochrane Central Register of Controlled Trials databases were searched to identify original RA drug therapy RCTs published in 2002-2003 and 2006-2007. Two reviewers independently assessed each RCT for the funding source, characteristics, outcome (positive [statistically significant result favoring experimental drug for the primary outcome] or not positive), and reporting of methodologic measures whose inadequate performance may have biased the assessment of treatment effect. RCTs that were registered at ClinicalTrials.gov and completed during the study years were assessed for publication bias. RESULTS: Of the 103 eligible RCTs identified, 58 (56.3%) were funded by industry, 19 (18.4%) were funded by nonprofit sources, 6 (5.8%) had mixed funding, and funding for 20 (19.4%) was not specified. Industry-funded RCTs had significantly more study centers and subjects, while nonprofit agency-funded RCTs had longer duration and were more likely to study different treatment strategies. Outcome could be assessed for 86 (83.5%) of the 103 RCTs studied. The funding source was not associated with a higher likelihood of positive outcomes favoring the sponsored experimental drug (75.5% of industry-funded RCTs had a positive outcome, compared with 68.8% of non-industry-funded RCTs, 40% of RCTs with mixed funding, and 81.2% of RCTs for which funding was not specified). Industry-funded RCTs showed a trend toward a higher likelihood of nonpublication (P=0.093). Industry-funded RCTs were more frequently associated with double-blinding, an adequate description of participant flow, and performance of an intent-to-treat analysis. CONCLUSION: Industry funding was not associated with a higher likelihood of positive outcomes of published RCTs of drug therapy for RA, and industry-funded RCTs performed significantly better than non-industry-funded RCTs in terms of reporting the use of some key methodologic quality measures.

The pervasiveness of microplastic contamination in the gastrointestinal tract of fish from the western coast of Bangladesh.

This study investigated the prevalence of microplastics (MPs) in the gastrointestinal tract (GIT) of fish from the western coast of Bangladesh, the world's largest mangrove ecosystem. Altogether, 8 different species of fish (5 demersal and 3 pelagic) were examined. Microplastics were detected in every individual fish with an average abundance of 7.1 ± 3.14 particles per specimen. The demersal species were observed to consume more microplastics (7.78 ± 3.51) than the pelagic species (5.92 ± 2.06). Moreover, small-sized fish was found to accumulate higher MPs/body weight than large-sized fish. Polypropylene was the most abundant polymer type (45 %) and fiber was the most prevalent shape (71 %). SEM analysis revealed cracks, pits, and foreign particles on the microplastics' surface, representing their ability to bear organic pollutants and heavy metals. This study will be a source of information for future research and a guide for policy-makers to take better actions to protect and restore marine resources.

Patient's global assessment of disease activity and patient's assessment of general health for rheumatoid arthritis activity assessment: are they equivalent?

OBJECTIVES: To assess (A) determinants of patient's global assessment of disease activity (PTGL) and patient's assessment of general health (GH) scores of rheumatoid arthritis (RA) patients; (B) whether they are equivalent as individual variables; and (C) whether they may be used interchangeably in calculating common RA activity assessment composite indices. METHODS: Data of 7023 patients from 30 countries in the Quantitative Standard Monitoring of Patients with RA (QUEST-RA) was analysed. PTGL and GH determinants were assessed by mixed-effects analyses of covariance models. PTGL and GH equivalence was determined by Bland-Altman 95% limits of agreement (BALOA) and Lin's coefficient of concordance (LCC). Concordance between PTGL and GH based Disease Activity Score 28 (DAS28), Clinical Disease Activity Index (CDAI) and Routine Assessment of Patient Index Data 3 (RAPID3) indices were calculated using LCC, and the level of agreement in classifying RA activity in four states (remission, low, moderate, high) using κ statistics. RESULTS: Significant differences in relative and absolute contribution of RA and non-RA related variables in PTGL and GH ratings were noted. LCC of 0.64 and BALOA of -4.41 to 4.54 showed that PTGL and GH are not equivalent. There was excellent concordance (LCC 0.95-0.99) for PTGL and GH based DAS28, CDAI and RAPID3 indices, and >80% absolute agreement (κ statistics 0.75-0.84) in RA activity state classification for all three indices. CONCLUSIONS: PTGL and GH ratings differ in their determinants. Although they are individually not equivalent, they may be used interchangeably for calculating composite indices for RA activity assessment.

Development of anti-neutrophil cytoplasmic antibody-associated vasculitis in a patient with Graves' disease independent of anti-thyroid drug therapy.

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) in patients with Graves' disease (GD) is linked with the use of anti-thyroid drugs (ATDs). We report the co-occurrence of AAV and GD in a patient that was independent of ATD therapy. A 38-year-old white male presented with systemic symptoms, palpitations, tremors, purpuric skin lesions, and digital pain. Physical examination and biological tests confirmed GD. He quickly developed multiple digital gangrenes and testicular pain/mass. Skin and testicular biopsies showed granulomatous vasculitis of the small- and medium-sized vessels, while his serum contained anti-proteinase-3 antibody.

Analysis of barriers and facilitators to early hearing detection and intervention in KwaZulu-Natal, South Africa.

BACKGROUND: There is slow progress in early hearing detection and intervention (EHDI) services within South Africa. Audiologists are EHDI gatekeepers and can provide valuable insights into the barriers and facilitators that can progressively move EHDI towards best practice in South Africa. OBJECTIVES: The study aimed to determine the barriers and facilitators to EHDI in KwaZulu-Natal as reported by audiologists/speech therapists and audiologists (A/STAs). METHOD: A descriptive qualitative approach was used. Telephonic interviews were conducted with 12 A/STAs working in public and private healthcare facilities, using the strengths, weaknesses, opportunities, threats (SWOT) conceptual framework. Data was analysed using thematic analysis in conjunction with NVivo software. RESULTS: One of the main barriers perceived by A/STAs, affecting EHDI was the lack of resources in healthcare facilities. The participants indicated that although there was a guideline in place to guide practice, it may be more suited to an urban area versus a rural area. Poor knowledge and awareness of EHDI was also identified as a barrier. Information provided from A/STAs at grassroots level, in the various provinces, may benefit in developing a more contextually relevant and practical guideline. Facilitators included; development of task teams specifically for EHDI programmes, creation of improved communication networks for collaboration and communication, training of healthcare professionals and improving data management systems. CONCLUSION: Strategies such as an increase in resources, further education and training, development of contextually relevant, culturally, and linguistically diverse practices and protocols need to be in place to improve EHDI implementation. Further research, clinical implications and limitations are provided emanating from the study.

Chiral Iodotriptycenes: Synthesis and Catalytic Applications.

Invited for this month's cover picture is the group of Thomas Wirth at Cardiff University (UK). The cover picture shows two structures of triptycenes. In each of these molecules all three aromatic rings are different with the rigid structure of the molecules making them chiral. The two sp3 -carbons shown in red and green are the stereocentres with defined configuration. These molecules contain the crucial iodine functionality which are utilised to generate hypervalent iodine(III)-catalysts in situ. The authors acknowledge Dr. Yu Wang for the creation of the cover image. Read the full text of their Research Article at 10.1002/open.202200145.

Chiral Iodotriptycenes: Synthesis and Catalytic Applications.

New iodotriptycenes, including some chiral derivatives, have been synthesised, and their catalytic potential towards oxidative transformations has been investigated. The enantioselectivities observed in the products using chiral iodotriptycene catalysts are low, probably owing to the large distances between the coordinating groups and the iodine moieties in these compounds.

Health sciences students' perception of the communicative impacts of face coverings during the COVID-19 pandemic at a South African University.

BACKGROUND:  The use of face masks and/or shields can pose a challenge during communication. They block facial expressions thus removing visual cues and affect sound transmission making it difficult to hear speech clearly. Given the widespread use of face coverings, it seems reasonable to clarify if communication in typical speakers and listeners has significantly differed. Health science students as future practitioners need to understand challenges that arise from using face coverings. OBJECTIVE:  This study aimed to determine health sciences students' perception of the communicative impacts of face coverings. METHOD:  The study employed a descriptive, self-administered online survey, obtaining information from 96 health science undergraduate students. RESULTS:  All participants changed their manner of speaking in that they spoke louder when wearing masks and focused more on eye contact when someone was wearing masks. These were statistically significant (p = 0.450 and p = 0.035 respectively). Fifty-three percent reported using more listening effort and feeling anxious when communicating. Approximately 33% indicated that it was challenging to read emotions, such as sad or unhappy, when someone wore a mask. Most, 61%, were positive or very positive about wearing masks. The level of difficulty differed depending on the listening environment. It was harder to understand the doctor, nurse, or other healthcare workers when they wore face coverings than when listening to their friends and family, which had little effect, this being statistically significant (p = 0.025). CONCLUSION:  Challenges envisaged in practice included frequent communication breakdowns, inability to connect and build trust between patient and practitioner, and communicating in noisy environments. Coping strategies, future clinical and research implications were proposed, and limitations acknowledged.

Ten years later: a review of the US 2009 institute of medicine report on conflicts of interest and solutions for further reform.

Conflicts of interest (COIs) in healthcare are increasingly discussed in the literature, yet these relationships continue to influence healthcare. Research has consistently shown that financial COIs shape prescribing practices, medical education and guideline recommendations. In 2009, the Institute of Medicine (IOM, now the National Academy of Medicine) published Conflicts of Interest in Medical Research, Practice, and Education-one of the most comprehensive reviews of empirical research on COIs in medicine. Ten years after publication of theIOM's report, we review the current state of COIs within medicine. We also provide specific recommendations for enhancing scientific integrity in medical research, practice, education and editorial practices.

Missing data in randomised controlled trials of rheumatoid arthritis drug therapy are substantial and handled inappropriately.

OBJECTIVES: To analyse the amount, reporting and handling of missing data, approach to intention-to-treat (ITT) principle application and sensitivity analysis utilisation in randomised clinical trials (RCTs) of rheumatoid arthritis (RA). To assess the trend in such reporting 10 years apart (2006 and 2016). METHODS: Parallel group drug therapy RA RCTs with a clinical primary endpoint. RESULTS: 176 studies enrolling a median of 160 (IQR 62-339) patients were eligible. In terms of actual analysis: 81 (46%) RCTs conducted ITT, 42 (23.9%) conducted modified ITT while 53 (30.1%) conducted non-ITT analysis. Only 58 of 97 (59.8%) RCTs reporting an ITT analysis actually performed it. The median (IQR) numbers of participants completing the trial and included in analysis for primary outcome were 86% (74%-91%) and 100% (97.1%-100%), respectively. 53 (32.7%) and 65 (40.1%) RCTs had >20% and 10%-20% missing primary outcome data, respectively. Missing data handling was unreported by 58 of 171 (33.9%) RCTs. When reported, vast majority used simple imputation methods. No significant trend towards improved reporting was seen between 2006 and 2016. Sensitivity analysis numerically improved from 2006 to 2016 (14.7% vs 21.4%). CONCLUSIONS: There is significant discrepancy in the reported and the actual performed analysis in RA drug therapy RCTs. Nearly one-third of RCTs had >20% missing data. The reporting and methods of missing data handling remain inadequate with high usage of non-preferred simple imputation methods. Sensitivity analysis utilisation was low. No trend towards better missing data reporting and handling was seen.

Management of adult patients with tinnitus: Preparedness, perspectives and practices of audiologists.

BACKGROUND: Audiologists, globally, are generally challenged when assessing and creating intervention plans to help patients suffering from tinnitus. Tinnitus is very common among individuals and may significantly affect one's quality of life, especially if not addressed by health care professionals. In South Africa, there seems to be limited published studies regarding the current practices of tinnitus management by audiologists. This is mainly because of limited training and a lack of guidelines and strategies for the management of tinnitus. In particular, some participants reported being unfamiliar on how to approach the identification of tinnitus and difficulty is also encountered when counselling tinnitus patients. AIM: The aim of this study was to describe the preparedness, perspectives and practices of audiologists who manage adult patients with tinnitus. METHOD: Two hundred and forty-three registered Health Professions Council of South Africa (HPCSA) participants were involved in the study by responding to an electronic questionnaire survey. Data were collected online from Survey Monkey and were exported to Statistical Packages for the Social Sciences (SPSS) (Version 23) for statistical analysis. Data were analysed using descriptive and inferential statistics. Closed-ended questions were analysed within a quantitative framework and thematic analysis for open-ended questions that were descriptively quantified. RESULTS: The results of the study are presented according to the objectives. Approximately 44% of participants (44.3%) disagreed that the undergraduate university training had sufficiently prepared them to manage adult patients with tinnitus. Very few (12.3%) had the opportunity to attend specialist training on how to assess patients with tinnitus. Similarly, only 11.6% received any specialist training with regard to tinnitus intervention. With regard to its overall management, 49.4% felt adequately informed in the assessment of patients with tinnitus, while a further 39.2% rated their experience as being limited with regard to tinnitus intervention. There is no statistical significance relationship between participants' years of experience and tinnitus intervention (p = 0.075). Most participants did not follow any standard guidelines for its management. Some participants (26.8%) reported that further education and training are required in the overall management of patients with tinnitus, while a further 17.7% required training in all areas of tinnitus. CONCLUSION: The feedback relating to the study suggests that overall management of tinnitus seems to be a challenge among South African audiologists, irrespective of their years of experience. Audiologists in the study perceived that tinnitus services are limited mainly because of a lack of or limited knowledge, training and guidelines, these being affected by contextual restraints.

Infection prevention and control measures in audiology practice within public healthcare facilities in KwaZulu-Natal province, South Africa.

BACKGROUND: Audiologists have a clinical and ethical responsibility to create a working environment, designed to reduce the potential for cross-contamination or transmission of infections. OBJECTIVES: To describe the infection prevention and control (IPC) measures utilised and the opinions of audiologists and speech therapists, and audiologists (A/STAs) towards IPC in public healthcare facilities in KwaZulu-Natal province, South Africa. METHOD: A quantitative, descriptive survey was utilised and entailed completing an online questionnaire. The Cronbach's alpha (0.82) indicated good internal consistency of the tool. Forty-nine A/STAs from 29 public healthcare facilities responded. RESULTS: Most participants (82%) followed a generic Department of Health policy on IPC, while 67% alluded to a discipline-specific policy. Participants had received training in infection control but indicated that further instruction was required for audiology-specific infection control procedures. Only 57% indicated that they 'sometimes' wore gloves with every patient during direct clinical contact. An association between the healthcare facility level and the wearing of gloves was found to be statistically significant (p = 0.025). Participants at regional and tertiary levels contended that gloves should be worn during most procedures versus those at district levels of care. While 96% washed their hands after each patient, only 76% washed their hands before each patient. Twenty-nine per cent indicated that they only 'sometimes' wore masks when in contact with patients with communicable diseases. Approximately one-third disinfected touch surfaces and toys, based on the clinician's discretion. The majority (86%) of participants, however, always followed the correct protocol for medical waste disposal. Despite training and the availability of policies, some practitioners displayed poor IPC practices in terms of universal precautions, personal protective equipment, handwashing and sterilisation. CONCLUSION: Further education, training and awareness related to appropriate IPC measures are recommended for audiologists. It is envisaged that this will lead to more effective IPC measures in audiology practice thereby reducing the risk of infection transmission.

Clinical profile and outcome of hospitalized patients during first outbreak of dengue in Makkah, Saudi Arabia.

OBJECTIVE: To describe clinical profile of patients with dengue virus infection hospitalized at a single center during the first outbreak of dengue in Makkah, Saudi Arabia from April to July 2004. METHODS: Clinical information and laboratory abnormalities of patients with suspected dengue infection were collected by a standardized data collection sheet and review of medical records. Dengue virus infection was confirmed by a positive IgM capture ELISA or RT-PCR. RESULTS: Of the 160 clinically suspected patients, 91 were confirmed (64 by IgM ELISA, 14 by RT-PCR and 13 by both) to have dengue virus infection. Dengue serotypes 2 and 3 were identified in 19 and 4 patients respectively. Most patients were young adults with median age of 26 (range=6-94) years and male:female ratio of 1.5:1. The common symptoms were fever (100%), malaise (83%), musculoskeletal pain (81%), headache (75%), nausea (69%), vomiting (65%) and abdominal pain (48%). According to World Health Organization (WHO) classification (10 patients were excluded due to lack of serial hematocrits), 75 (93%) had dengue fever (DF) and 6 (7%) had dengue hemorrhagic fever (DHF). Only one patient with DHF was in pediatric age group. Twenty-one patients (5 with DHF and 16 with DF) developed one or more clinical complications that included bleeding (14), shock (4), seizures (3), acute renal failure (2), meningo-encephalitis (1), and secondary bacterial infection (1). Only one patient with shock had dengue shock syndrome (DSS) by WHO classification. Development of clinical complications was significantly associated with absence of musculoskeletal pain (p-value=0.03), lower platelet counts (p-value=0.03) and higher serum aspartate aminotransferase levels (p-value=0.04). The median duration of symptoms and hospitalization was 8 days (range=3-18) and 4 days (range=1-10) respectively. No mortality was noted. CONCLUSION: Occurrence of dengue virus infection in Makkah, Saudi Arabia is documented. Continued surveillance and effective vector control programs are warranted due to unique population dynamics of Makkah that receives millions of pilgrims annually from all over the world.

The hearing screening experiences and practices of primary health care nurses: Indications for referral based on high-risk factors and community views about hearing loss.

BACKGROUND:  In South Africa, primary health care is the first point of contact with the health system for at least 85% of the population, yet early hearing detection and intervention continues to be elusive in these settings. Nurses at community level may, therefore, be missing an opportunity to identify prelingual infants with hearing losses and alter their developmental trajectory. AIM:  To determine primary health care nurses' experiences, practices and beliefs regarding hearing loss in infants. SETTING:  The study was conducted in the eThekwini District of KwaZulu-Natal, South Africa. METHODS:  A descriptive survey was used with quantitative methods of analysis. Fourteen primary health care clinics from the eThekwini district were selected, from which 75 nurses participated by completing a self-administered questionnaire. RESULTS:  At least one-third of primary health care nurses had never screened a child for hearing loss, and most clinics did not have access to basic hearing screening equipment or materials. Only 49% of nurses had access to an otoscope, while 31% used the Road to Health Development screener to check for hearing loss. None of the clinics had access to an otoacoustic emission screener nor the Swart questionnaire. Although nurses reported that they would refer to audiology services for some of the risk factors, as indicated on the Joint Committee on Infant Hearing (JCIH) 2007 list, they were less likely to refer if the child was in a neonatal intensive care unit (ICU) longer than five days, had neurodegenerative disorders, meningitis, hyperbilirubinaemia requiring blood transfusion or were undergoing chemotherapy. Less than a third of nurses always referred if the child displayed additional non-JCIH risk factors or those pertinent to the South African context. Approximately 38% reported that communities believed that hearing loss could be because of some form of spiritual or supernatural causes. CONCLUSION:  This study demonstrates that hearing screening and referral practices at primary health care clinics need to be strengthened. Nurses need to be capacitated to conduct basic screening, make necessary referrals, provide information to caregivers and understand community beliefs about hearing loss in order to counsel caregivers appropriately and facilitate the process of early hearing detection and intervention.

Tools for the Assessment of Comorbidity Burden in Rheumatoid Arthritis.

INTRODUCTION: Comorbidities influence the prognosis, clinical outcomes, disease activity, and treatment response in rheumatoid arthritis (RA). RA patients have a high-comorbidity burden necessitating their study. Comorbidity indices are used to measure comorbidities and to study their impacts on different outcomes. A large number of such indices are used in clinical research. Some indices have been specifically developed in RA patients. AIM: This review aims to provide an overview of generic and specific comorbidity indices commonly used in RA research. METHODS: We performed a critical literature review of comorbidity indices in RA using the PubMed database. RESULTS/DISCUSSION: This non-systematic literature review provides an overview of generic and specific comorbidity indices commonly used in RA studies. Some of the older but commonly used comorbidity indices like the Charlson comorbidity index and the Elixhauser comorbidity measure were primarily developed to estimate mortality risk from comorbid diseases. They were not specifically developed for RA patients but have been widely used in rheumatology comorbidity measurement. Of the many comorbidity indices available, only the rheumatic disease comorbidity index (RDCI) and the multimorbidity index have been specifically developed in RA patients. The functional comorbidity index was developed to look at functional disability and has been used in RA patients considering that morbidity is more important than mortality in such patients. While there is limited data comparing these indices, available evidence seems to favor the use of RDCI as it predicts mortality, hospitalization, disability, and healthcare utilization. The choice of the index, however, depends on several factors such as the population under study, outcome of interest, and sources of data. More research is needed to study the RA-specific comorbidity measures to make evidence-based recommendations for the choice of a comorbidity measure.

Scientific productivity: An exploratory study of metrics and incentives.

Competitive pressure to maximize the current bibliometric measures of productivity is jeopardizing the integrity of the scientific literature. Efforts are underway to address the 'reproducibility crisis' by encouraging the use of more rigorous, confirmatory methods. However, as long as productivity continues to be defined by the number of discoveries scientists publish, the impact factor of the journals they publish in and the number of times their papers are cited, they will be reluctant to accept high quality methods and consistently conduct and publish confirmatory/replication studies. This exploratory study examined a sample of rigorous Phase II-IV clinical trials, including unpublished studies, to determine if more appropriate metrics and incentives can be developed. The results suggest that rigorous procedures will help reduce false positives, but to the extent that higher quality methods are accepted as the standard of practice, the current bibliometric incentives will discourage innovative studies and encourage scientists to shift their research to less informative studies of subjects that are already being more actively investigated. However, the results also suggest that it is possible to develop a more appropriate system of rewards. In contrast to the current bibliometric incentives, evaluations of the quality of the methods and reproducibility of the results, innovation and diversity of thought, and amount of information produced may serve as measures and incentives that maintain the integrity of the scientific literature and maximize scientific progress.
