Drivers of overall satisfaction with primary care: Evidence from the English General Practice Patient Survey

This is the final version. Available from Wiley via the DOI in this record.Background/objectives: To determine which aspects of primary care matter most to patients, we aim to identify those aspects of patient experience that show the strongest relationship with overall satisfaction and examine the extent to which these relationships vary by socio-demographic and health characteristics. Design/setting: Data from the 2009/10 English General Practice Patient Survey including 2 169 718 respondents registered with 8362 primary care practices. Measures/analyses: Linear mixed-effects regression models (fixed effects adjusting for age, gender, ethnicity, deprivation, self-reported health, self-reported mental health condition and random practice effect) predicting overall satisfaction from six items covering four domains of care: access, helpfulness of receptionists, doctor communication and nurse communication. Additional models using interactions tested whether associations between patient experience and satisfaction varied by socio-demographic group. Results: Doctor communication showed the strongest relationship with overall satisfaction (standardized coefficient 0.48, 95% CI = 0.48, 0.48), followed by the helpfulness of reception staff (standardized coefficient 0.22, 95% CI = 0.22, 0.22). Among six measures of patient experience, obtaining appointments in advance showed the weakest relationship with overall satisfaction (standardized coefficient 0.06, 95% CI = 0.05, 0.06). Interactions showed statistically significant but small variation in the importance of drivers across different patient groups. Conclusions: For all patient groups, communication with the doctor is the most important driver of overall satisfaction with primary care in England, along with the helpfulness of receptionists. In contrast, and despite being a policy priority for government, measures of access, including the ability to obtain appointments, were poorly related to overall satisfaction.UK Department of HealthNational Institute for Health Research (NIHR

Prevalence of polycyclic aromatic hydrocarbons (PAHs) degrading bacteria in contaminated tropical soil in Lagos, Nigeria: involvement of plasmid in degradation

Recalcitrant pollutants such as polycyclic aromatic hydrocarbons (PAHs) are difficult to degrade and have been the focus for biodegradation. They form a class of pollutant on a global scale. In an attempt to contribute to the search for suitable microbial culture with potential to biodegrade low and high molecular weight PAHs, bacterial strains were isolated from engine-oil polluted sites in Lagos, Nigeria. These isolates were evaluated for possession of plasmid DNA and the role it played in PAH degradation. Out of sixteen strains isolated, two were Gram negative while the others were Gram positive isolates. They belonged to genera Micrococcus, Staphylococcus, Kurthia sp., Acinetobacter, Pseudomonas and Corynebacterium. All the isolates grew on the PAHs (anthracene, fluoranthene and pyrene) at varying rates utilizing them as sole sourceof carbon and energy. All the isolates also possessed plasmid DNA ranging from 17.8 to 38.9 kbp. Subjection of plasmid cured isolates to PAHs biodegradation suggest that PAHs degradation may be plasmid and/orchromosomally mediated depending on the bacterial isolate and PAHs being degraded. This study has revealed that different compounds induce varied genetic changes in bacterial isolates in response to the stimuli

Construction of expression vectors carrying mouse peroxisomal protein gene (PeP) with GST and Flag labels

The aim of this study was to construct expression vectors carrying mouse peroxisomal protein gene (PEP-cDNA) in prokaryotic and mammalian expression vectors in chimeric cDNA types, encompassingGST and FLAG with PEP-cDNA. PEP-cDNA was sub-cloned in pGEX6p2 prokaryotic expression vector in order to label this gene with GST to purify PEP protein for further biochemical analysis and identifying related proteins thereafter. FLAG-PEP recombinant DNA was produced and sub-cloned inpUcD3 eukaryotic expression vector to express tagged-PEP protein for transient transfection analysis and identifying intracellular localization of PEP protein in future experiments. PEP-cDNA was amplifiedin different PCR reactions using pEGFP-PEP vector and 2 sets of primers introducing specific restriction sites at the ends of PEP. PCR products with BamHI/SalI restriction sites were treated by restriction enzymes and inserted into the pGEX6p2, downstream of GST tag. PEP-cDNA containingBamHI/ApaI restriction sites and FLAG gene (which amplified using pUcD3-FLAG-PEX3 vector) were used as templates in secondary PCR for amplifying FLAG-PEP recombinant DNA. FLAG-PEP fragment was treated by enzymatic digestion and inserted into the pUcD3 eukaryotic expression vector.pGEX6p2-PEP and pUcD3-FLAG-PEP constructed vectors were transformed into the one shot TOP10 and JM105 bacterial competent cells, respectively. Positive colonies were selected for plasmid preparation. Results confirmed correct amplification of the expected products. PEP-cDNA in both PCRreactions encompasses 630 bp. FLAG fragment containing designed sites was 77 bp and FLAG-PEP fragment was 700 bp. Sequencing of constructed vectors confirmed that PEP-cDNA was tagged appropriately and inserted free of mutation and in frame with GST and FLAG

A mixed methods approach to evaluating community drug distributor performance in the control of neglected tropical diseases

BACKGROUND: Trusted literate, or semi-literate, community drug distributors (CDDs) are the primary implementers in integrated preventive chemotherapy (IPC) programmes for Neglected Tropical Disease (NTD) control. The CDDs are responsible for safely distributing drugs and for galvanising communities to repeatedly, often over many years, receive annual treatment, create and update treatment registers, monitor for side-effects and compile treatment coverage reports. These individuals are 'volunteers' for the programmes and do not receive remuneration for their annual work commitment. METHODS: A mixed methods approach, which included pictorial diaries to prospectively record CDD use of time, structured interviews and focus group discussions, was used to triangulate data on how 58 CDDs allocated their time towards their routine family activities and to NTD Programme activities in Uganda. The opportunity costs of CDD time were valued, performance assessed by determining the relationship between time and programme coverage, and CDD motivation for participating in the programme was explored. RESULTS: Key findings showed approximately 2.5 working weeks (range 0.6-11.4 working weeks) were spent on NTD Programme activities per year. The amount of time on NTD control activities significantly increased between the one and three deliveries that were required within an IPC campaign. CDD time spent on NTD Programme activities significantly reduced time available for subsistence and income generating engagements. As CDDs took more time to complete NTD Programme activities, their treatment performance, in terms of validated coverage, significantly decreased. Motivation for the programme was reported as low and CDDs felt undervalued. CONCLUSIONS: CDDs contribute a considerable amount of opportunity cost to the overall economic cost of the NTD Programme in Uganda due to the commitment of their time. Nevertheless, programme coverage of at least 75 %, as required by the World Health Organisation, is not being achieved and vulnerable individuals may not have access to treatment as a consequence of sub-optimal performance by the CDDs due to workload and programmatic factors

Red blood cell distribution width: Genetic evidence for aging pathways in 116,666 volunteers

This is the final version of the article. Available from Public Library of Science via the DOI in this record.INTRODUCTION: Variability in red blood cell volumes (distribution width, RDW) increases with age and is strongly predictive of mortality, incident coronary heart disease and cancer. We investigated inherited genetic variation associated with RDW in 116,666 UK Biobank human volunteers. RESULTS: A large proportion RDW is explained by genetic variants (29%), especially in the older group (60+ year olds, 33.8%, <50 year olds, 28.4%). RDW was associated with 194 independent genetic signals; 71 are known for conditions including autoimmune disease, certain cancers, BMI, Alzheimer's disease, longevity, age at menopause, bone density, myositis, Parkinson's disease, and age-related macular degeneration. Exclusion of anemic participants did not affect the overall findings. Pathways analysis showed enrichment for telomere maintenance, ribosomal RNA, and apoptosis. The majority of RDW-associated signals were intronic (119 of 194), including SNP rs6602909 located in an intron of oncogene GAS6, an eQTL in whole blood. CONCLUSIONS: Although increased RDW is predictive of cardiovascular outcomes, this was not explained by known CVD or related lipid genetic risks, and a RDW genetic score was not predictive of incident disease. The predictive value of RDW for a range of negative health outcomes may in part be due to variants influencing fundamental pathways of aging.This work was supported by an award to DM, TF, AM and LH by the UK Medical Research Council (grant number MR/M023095/1).

Knowledge, attitudes and practice of breast cancer screening among female health workers in a Nigerian urban city

<p>Abstract</p> <p>Background</p> <p>Late presentation has been observed as the hallmark of breast cancer in Nigerian women and an earlier onset has been reported in this population. This study was designed to assess the awareness of female health workers about risk factors and screening methods for early detection of breast cancer.</p> <p>Methods</p> <p>A cross-sectional descriptive study was carried out among female health workers in the two major government health institutions in Benin City, Edo State capital in Nigeria.</p> <p>Data analysis was by SPSS version 10 and test of significance was done with differences considered significant at p < 0.05.</p> <p>Results</p> <p>Three hundred and ninety-three (393) female health workers out of five hundred and five eligible subjects completed and returned the questionnaires, giving a response rate of 77.8%. One hundred and two (26%) were Doctors, two hundred and fifty-four (64.6%) Nurses, and thirty-seven (9.4%) were Radiographers, Laboratory Scientists and Pharmacists. A high proportion of our respondents had very poor knowledge about risk factors for breast cancer (55%). The awareness of mammography as a diagnostic method was very high (80.7%), but an extremely low knowledge of mammography as a screening method was found. Mammography practice of only 3.1% was found among those above 40 years of age who qualify for routine annual screening. Relatively low knowledge (45.5%) about Breast Self Examination (BSE) as a screening method was found.</p> <p>Conclusion</p> <p>These female health workers who are expected to act as role models and educate the public had poor knowledge of risk factors for breast cancer and practice of breast cancer screening. There is very urgent need for regular update courses for health workers concerning breast cancer education including screening methods.</p

Multi-centre reproducibility of diffusion MRI parameters for clinical sequences in the brain.

The purpose of this work was to assess the reproducibility of diffusion imaging, and in particular the apparent diffusion coefficient (ADC), intra-voxel incoherent motion (IVIM) parameters and diffusion tensor imaging (DTI) parameters, across multiple centres using clinically available protocols with limited harmonization between sequences. An ice-water phantom and nine healthy volunteers were scanned across fives centres on eight scanners (four Siemens 1.5T, four Philips 3T). The mean ADC, IVIM parameters (diffusion coefficient D and perfusion fraction f) and DTI parameters (mean diffusivity MD and fractional anisotropy FA), were measured in grey matter, white matter and specific brain sub-regions. A mixed effect model was used to measure the intra- and inter-scanner coefficient of variation (CV) for each of the five parameters. ADC, D, MD and FA had a good intra- and inter-scanner reproducibility in both grey and white matter, with a CV ranging between 1% and 7.4%; mean 2.6%. Other brain regions also showed high levels of reproducibility except for small structures such as the choroid plexus. The IVIM parameter f had a higher intra-scanner CV of 8.4% and inter-scanner CV of 24.8%. No major difference in the inter-scanner CV for ADC, D, MD and FA was observed when analysing the 1.5T and 3T scanners separately. ADC, D, MD and FA all showed good intra-scanner reproducibility, with the inter-scanner reproducibility being comparable or faring slightly worse, suggesting that using data from multiple scanners does not have an adverse effect compared with using data from the same scanner. The IVIM parameter f had a poorer inter-scanner CV when scanners of different field strengths were combined, and the parameter was also affected by the scan acquisition resolution. This study shows that the majority of diffusion MRI derived parameters are robust across 1.5T and 3T scanners and suitable for use in multi-centre clinical studies and trials

Assessment of knowledge about childhood autism among paediatric and psychiatric nurses in Ebonyi state, Nigeria

<p>Abstract</p> <p>Background</p> <p>There is increasing public and professional awareness of autism spectrum disorders with early recognition, diagnosis and interventions that are known to improve prognosis. Poor knowledge about childhood autism among paediatric and psychiatric nurses who are members of multidisciplinary teams that care for such children may be a major barrier to early interventions that could improve quality of life and prognosis in childhood autism. Factors that influence knowledge about childhood autism among these nurses are not known. This study assessed knowledge about childhood autism among paediatric and psychiatric nurses in Ebonyi state, Nigeria and determined the factors that could be influencing such knowledge.</p> <p>Methods</p> <p>Forty specialist paediatric and forty psychiatric nurses, making a total sample of eighty, were randomly selected from all the health care facilities in Ebonyi state, Nigeria. A socio-demographic questionnaire and knowledge about childhood autism among health workers (KCAHW) questionnaire were administered to them and the study was a point survey.</p> <p>Results</p> <p>The total mean score on the KCAHW questionnaire among the nurses that participated in the study was 12.56 ± 3.23 out of a total of 19 possible. The mean score for the paediatric nurses was 11.78 ± 3.64 while psychiatric nurses had mean score of 13.35 ± 2.58. The mean scores in Domain 1 were 6.17 ± 1.75 for the paediatric nurses and 6.52 ± 1.43 for the psychiatric nurses. The mean scores in Domain 2 were 0.65 ± 0.48 for the paediatric nurses and 0.80 ± 0.41 for the psychiatric nurses. Domain 3 showed mean scores of 1.97 ± 1.25 for the paediatric nurses while psychiatric nurses scored 2.62 ± 1.23. Domain 4 yielded the mean scores of 2.97 ± 1.54 and 3.42 ± 0.98 for the paediatric and psychiatric nurses respectively.</p> <p>There was significant relationship between the total mean score on the KCAHW questionnaire for the two groups and the area of specialisation of the nurses (t = -2.23, df = 78, p = 0.03) and there was also significant relationship between previous involvement in managing children with childhood autism as a specialist paediatric or psychiatric nurse and the total mean score on the KCAHW questionnaire (t = 6.90, df = 78, p = 0.00).</p> <p>Conclusion</p> <p>The scores reflect deficits in knowledge about childhood autism among the study cohorts. Paediatric and psychiatric nurses as members of multidisciplinary teams that care for children with childhood autism are expected to provide holistic care and adequate counselling to the families of these children. Unfortunately in this environment, they are not fully equipped with enough knowledge about childhood autism. Education on childhood autism is therefore needed and can be provided through continuing medical education and emphasizing childhood autism in their training curriculum. This will enhance early identification and diagnosis of childhood autism with early interventions that are known to improve prognosis.</p
