An examination of how the ‘Household Model' of care can contribute to positive ageing for residents in the ‘Fourth Age’

Background: Promoting a good quality of life for the oldest members of society has become a top priority as evidenced in UK policy. The ‘household’ model is a departure from traditional approaches to care provision since it offers person-centred support - combining health and social care - to older people in specially-designed, small, homelike environments. Having gained increasing popularity in care homes across developed countries, the impact of this model of service delivery on residents’ quality of life and its contribution to positive ageing is of increasing interest. Belong is a not-for-profit, UK care organisation currently operating several villages under the household model. The villages comprise independent living apartments (bought or rented) and residential/nursing care households offering 24 hours personalised, on-site care for residents. In each village there is a range of facilities open to the public (including a Bistro, hairdressers and gym facilities) and a domiciliary community service. Methods: In this paper we present new data generated from qualitative interviews with a sample of household residents in the ‘Fourth Age’ and relatives across two villages in the North West of England, UK. Results: We examine how the household model as operated at Belong facilitates the maintenance of autonomy and independence - which underpins positive ageing and quality of life in the fourth age - among residents. Conclusion: We show how the household model contributes to positive ageing and quality of life as defined by residents

Ground scintillometric investigations of parts of Kerri-Kerri formation, south – west Gombe, north - eastern Nigeria

A ground scintillometric survey was carried out in the south - western part of the Kerri - Kerri Formation to identify areas of more prominent radioactive anomalies for further detailed spectrometric investigation. The total count rates recorded were generally higher in the south – western part of the study area. Analysis of the reduced data reveals the threshold activity value for the study area is 27.5 cps. Activities of more than twice the mode that will be of significance in terms of mineralization is 40 cps observed in the area north east of Tumu village with occurrence of granitic feldspar. The cosmic ray contribution to the ground activity measured in the field and used for the background correction is 4 cps. Detailed ground spectrometric investigation should be carried out in the area north – east of Tumu village to determine the radiometric mineralization potentials of the area and confirm if the radiation is due to the rocks or soil of the area.KEYWORDS: Scintillometric, Total count rates, Background correction, Threshold activity, Mineralization

Breast-Lesion Characterization using Textural Features of Quantitative Ultrasound Parametric Maps

© 2017 The Author(s). This study evaluated, for the first time, the efficacy of quantitative ultrasound (QUS) spectral parametric maps in conjunction with texture-analysis techniques to differentiate non-invasively benign versus malignant breast lesions. Ultrasound B-mode images and radiofrequency data were acquired from 78 patients with suspicious breast lesions. QUS spectral-analysis techniques were performed on radiofrequency data to generate parametric maps of mid-band fit, spectral slope, spectral intercept, spacing among scatterers, average scatterer diameter, and average acoustic concentration. Texture-analysis techniques were applied to determine imaging biomarkers consisting of mean, contrast, correlation, energy and homogeneity features of parametric maps. These biomarkers were utilized to classify benign versus malignant lesions with leave-one-patient-out cross-validation. Results were compared to histopathology findings from biopsy specimens and radiology reports on MR images to evaluate the accuracy of technique. Among the biomarkers investigated, one mean-value parameter and 14 textural features demonstrated statistically significant differences (p < 0.05) between the two lesion types. A hybrid biomarker developed using a stepwise feature selection method could classify the legions with a sensitivity of 96%, a specificity of 84%, and an AUC of 0.97. Findings from this study pave the way towards adapting novel QUS-based frameworks for breast cancer screening and rapid diagnosis in clinic

A case of pregnancy with Rhesus antibody and bicornuate uterus - a favourable outcome: a case report

Introduction: In 1% of Rhesus negative women sensitisation occurs without any overt sensitising event during pregnancy. This accounts for late immunisation during a first pregnancy and is responsible for 18-27% of cases of alloimmunisation. The incidence of congenital uterine anomalies in a fertile population is 3.2% of which 5% are bicornuate uterus. Bicornuate uterus can lead to early miscarriages, preterm labor, fetal growth retardation and congenital malformations. Case presentation: A 23-year-old lady in her first pregnancy developed Anti-D antibodies at 28 weeks of gestation without any known sensitising event. In view of increasing anti-D titres, at 36 weeks she was delivered. Incidentally during caesarean section she was found to have bicornuate uterus. The neonate was treated with phototherapy and blood transfusion following delivery. Conclusion: Rhesus antibodies when managed by close monitoring and timely delivery can lead to favourable outcome. Bicornuate uterus does not always lead to complications like miscarriage, growth retardation or preterm labour and does not need any special intervention

A framework for automatic semantic video annotation

The rapidly increasing quantity of publicly available videos has driven research into developing automatic tools for indexing, rating, searching and retrieval. Textual semantic representations, such as tagging, labelling and annotation, are often important factors in the process of indexing any video, because of their user-friendly way of representing the semantics appropriate for search and retrieval. Ideally, this annotation should be inspired by the human cognitive way of perceiving and of describing videos. The difference between the low-level visual contents and the corresponding human perception is referred to as the ‘semantic gap’. Tackling this gap is even harder in the case of unconstrained videos, mainly due to the lack of any previous information about the analyzed video on the one hand, and the huge amount of generic knowledge required on the other. This paper introduces a framework for the Automatic Semantic Annotation of unconstrained videos. The proposed framework utilizes two non-domain-specific layers: low-level visual similarity matching, and an annotation analysis that employs commonsense knowledgebases. Commonsense ontology is created by incorporating multiple-structured semantic relationships. Experiments and black-box tests are carried out on standard video databases for action recognition and video information retrieval. White-box tests examine the performance of the individual intermediate layers of the framework, and the evaluation of the results and the statistical analysis show that integrating visual similarity matching with commonsense semantic relationships provides an effective approach to automated video annotation

Knowledge, attitudes, and willingness of healthcare workers in Iraq’s Kurdistan region to vaccinate against human monkeypox: a nationwide cross-sectional study

Although human monkeypox infections had not been recorded in the Kurdistan region of Iraq as of August 2023, the rapid growth of cases worldwide and the detection of monkeypox in neighboring Middle Eastern nations call for careful planning and timely response measures. Educating and empowering frontline healthcare workers (HCWs) so that they can act to curb the spread of monkeypox infections are core elements of primary prevention and protecting public health. Therefore, this study aimed to assess HCWs’ knowledge and attitudes about monkeypox and their willingness to vaccinate against monkeypox. By employing a convenience sampling method, an online survey was disseminated via Google Forms between 1 November 2022 and 15 January 2023. The researchers utilized regression analyses to ascertain the factors associated with the three parameters: knowledge, attitude, and the willingness to vaccinate. A total of 637 HCWs were included in the analysis (ages ranged between 21 and 51 years). The mean overall scores were 8.18 of a max score of 16 (SD 3.37), 3.4 of 5 (SD 1.37), and 2.41 of 5 (SD 1.25) for knowledge, attitude, and willingness to vaccinate, respectively. A multivariate logistic regression analysis demonstrated that HCWs who had heard about monkeypox before 2022 rather than later had a higher level of knowledge (AOR: 4.85; 95% CI: 2.81–8.36; p < 0.001). In addition, those who had newly joined the workforce or had less than 1 year experience in practice had more positive attitudes about curbing monkeypox (AOR: 0.35; 95% CI: 0.20–0.59; p < 0.01) than those who practiced for longer. No significant predictors of willingness to vaccinate against monkeypox were identified. The research revealed that HCWs exhibited a relatively low level of monkeypox knowledge. They also had poor attitudes towards monkeypox vaccination and were therefore reluctant to receive the vaccines. Imparting knowledge about the infectious disease can cultivate better awareness and attitudes among HCWs as to their roles in mitigating the spread of an epidemic in the foreseeable future

Post-mortem culture of Balamuthia mandrillaris from the brain and cerebrospinal fluid of a case of granulomatous amoebic meningoencephalitis, using human brain microvascular endothelial cells.

The first isolation in the UK of Balamuthia mandrillaris amoebae from a fatal case of granulomatous amoebic meningoencephalitis is reported. Using primary cultures of human brain microvascular endothelial cells (HBMECs), amoebae were isolated from the brain and cerebrospinal fluid (CSF). The cultures showed a cytopathic effect at 20-28 days, but morphologically identifiable B. mandrillaris amoebae were seen in cleared plaques in subcultures at 45 days. The identification of the organism was later confirmed using PCR on Chelex-treated extracts. Serum taken while the patient was still alive reacted strongly with slide antigen prepared from cultures of the post-mortem isolate, and also with those from a baboon B. mandrillaris strain at 1:10,000 in indirect immunofluorescence, but with Acanthamoeba castellanii (Neff) at 1:160, supporting B. mandrillaris to be the causative agent. If the presence of amoebae in the post-mortem CSF reflects the condition in life, PCR studies on CSF and on biopsies of cutaneous lesions may also be a valuable tool. The role of HBMECs in understanding the interactions of B. mandrillaris with the blood-brain barrier is discussed
