Compensation for effects of ambient temperature on rare-earth doped fiber optic thermometer

Variations in ambient temperature have a negative effect on the performance of any fiber optic sensing system. A change in ambient temperature may alter the design parameters of fiber optic cables, connectors, sources, detectors, and other fiber optic components and eventually the performance of the entire system. The thermal stability of components is especially important in a system which employs intensity modulated sensors. Several referencing schemes have been developed to account for the variable losses that occur within the system. However, none of these conventional compensating techniques can be used to stabilize the thermal drift of the light source in a system based on the spectral properties of the sensor material. The compensation for changes in ambient temperature becomes especially important in fiber optic thermometers doped with rare earths. Different approaches to solving this problem are searched and analyzed

Multiple Myeloma: A Review of Imaging Features and Radiological Techniques

The recently updated Durie/Salmon PLUS staging system published in 2006 highlights the many advances that have been made in the imaging of multiple myeloma, a common malignancy of plasma cells. In this article, we shall focus primarily on the more sensitive and specific whole-body imaging techniques, including whole-body computed tomography, whole-body magnetic resonance imaging, and positron emission computed tomography. We shall also discuss new and emerging imaging techniques and future developments in the radiological assessment of multiple myeloma

Artificial Neural Networks for Classification in Metabolomic Studies of Whole Cells Using 1H Nuclear Magnetic Resonance

We report the successful classification, by artificial neural networks (ANNs), of 1H NMR spectroscopic data recorded on whole-cell culture samples of four different lung carcinoma cell lines, which display different drug resistance patterns. The robustness of the approach was demonstrated by its ability to classify the cell line correctly in 100% of cases, despite the demonstrated presence of operator-induced sources of variation, and irrespective of which spectra are used for training and for validation. The study demonstrates the potential of ANN for lung carcinoma classification in realistic situations

Mycophenolate mofetil treatment for primary glomerular diseases

Mycophenolate mofetil treatment for primary glomerular diseases.BackgroundTreatment of primary glomerular diseases may be unsuccessful or have potential toxicities. Therefore, we evaluated the use of mycophenolate mofetil (MMF) for empirical treatment of primary glomerulopathies.MethodsForty-six patients with biopsy-proven primary glomerulopathies received MMF for ≥3 months as adjunctive or primary treatment. Median (range) 24-hour urine protein to creatinine ratio (Up/c) and serum creatinine at the start and end of MMF therapy were compared using the Wilcoxon signed-ranks test.ResultsOverall, the median Up/c decreased from 4.7 (range <0.1, 20.3) to 1.1 (<0.1, 14.3; P < 0.001) at the end of MMF treatment with no significant change in median serum creatinine 1.3 (0.6 to 6.1) to 1.2 (0.5 to 6.5) mg/dL. Median serum albumin increased from 3.4 (1.4, 4.6) to 4.1 (1.7, 48) g/dL (P < 0.001) and the median serum cholesterol decreased from 270 (148, 795) to 220 (140, 309) mg/dL (P < 0.001) post-treatment. For those with minimal change disease, a complete steroid withdrawal was accomplished in 5/6 steroid dependent patients. Focal segmental glomerulosclerosis (FSGS) patients had a median Up/c that decreased from 2.7 (0.1, 20.3) to 0.8 (<0.1, 8.2; P = 0.001) in 18 patients. In membranous nephropathy (MN) patients, the median Up/c decreased from 7.3 (0.1, 18.5) to 1.5 (<0.1, 14.3) (P = 0.001) in 17 patients. No significant change in median serum creatinine was detected in FSGS or MN patient groups during treatment.ConclusionsEmpirical MMF therapy in the majority of patients with primary glomerulopathies was well tolerated and achieved the goals of steroid withdrawal, improvement of nephrotic syndrome, and stabilization of renal function

Sexuality and intimacy among people with serious mental illness: a qualitative systematic review

OBJECTIVE: The aim of this systematic review was to synthesize the best available qualitative evidence on the experiences and support needs of people with serious mental illness (SMI) regarding sexuality and intimacy within hospital and community settings. The objectives were to explore intimate relationship experiences of people with SMI, to uncover potential obstacles to the expression of sexuality and to present recommendations for mental health policy, education, research and practice. INTRODUCTION: Mental health services worldwide have seen major transformations in recent years through deinstitutionalization programs and more enlightened ways of organizing and providing mental health care. However, in terms of social and emotional wellbeing, issues persist for people with SMI, particularly relating to intimacy and the expression of sexuality. This systematic review may assist service providers to determine ways that they may better support people in establishing and maintaining satisfying intimate relationships and the full expression of their sexuality. INCLUSION CRITERIA: This review explored the intimacy and sexuality experiences, perceptions and concerns of people over the age of 18 years who were living with a SMI in hospital or community settings. This review considered studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research. METHODS: The databases MEDLINE, CINAHL, PsycINFO, Embase and Web of Science were utilised in the review. The search included studies published from 1995 up to and including February 6, 2018 and were limited to those in the English language. Each paper was assessed by two independent reviewers for methodological quality using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research. Any disagreements that arose between the reviewers were resolved through discussion. Data extraction was conducted by two independent reviewers using the standardized qualitative data extraction tool from JBI. The qualitative research findings were pooled using JBI methodology. The JBI process of meta-aggregation was used to identify categories and synthesized findings. RESULTS: Based on the thematic findings from the 21 studies, three synthesized findings were extracted from 10 categories and 83 findings: 1) the complexity of individual sexual experiences, 2) the clinical constructs of sexuality and 3) family and partner involvement. CONCLUSIONS: Having fulfilling and satisfying sexual and relationship experiences is a fundamental human right that can enhance an individual's quality of life. Being aware of the potential stresses and challenges that having a SMI can have on a relationship and involving partners in the treatment, may help to promote intimacy and recovery. Practitioners can use these findings to guide future policy, education and developments in practice. Further research is required to develop and evaluate interventions that target the identified barriers and help people with SMI to fulfil their unmet sexuality and intimacy needs

Youths with asthma and their experiences of self-management education: A systematic review of qualitative evidence

AIMS: To identify and synthesize the available evidence of youths with asthma and their experience of self-management education. DESIGN: Systematic literature review of qualitative studies with meta-synthesis of findings. DATA SOURCES: We searched five databases, CINAHL Complete, Embase, MEDLINE (EBSCO) PsycINFO, ASSIA and the Global Index Medicus (formerly the WHOLIS). Initial search in September 2019 and updated in July 2020 and July 2022. REVIEW METHODS: The systematic review was conducted in accordance with the JBI methodology for systematic reviews of qualitative evidence. Qualitative data were extracted, meta-summarized and then meta-synthesized. RESULTS: Eighteen studies were identified for inclusion in this review and three themes were identified: The theory and practice gap, contemporary health-seeking preferences and the psychosocial impacts of living with asthma. CONCLUSION: The needs of youths with asthma are specific and must be measurable against the change in asthma outcomes for this group. They have unmet self-management educational needs that stakeholders, involved in their care and support, should address. Education and practice policy should focus on youth-centric approaches. Through meaningful engagement with youths, stakeholders can identify their support needs, requirements and preferences to successfully underpin the theory and practice of self-management education. IMPACT: This review synthesized evidence of youths with asthma and their experiences of self-management education, highlighting their specific self-management information needs. The findings highlight several implications for healthcare professionals in education, practice and research. This age profile is under-explored and further research into this population would work towards filling the theory and practice gap and highlighting the identified psychosocial issues faced by this group

Irritant contact dermatitis in healthcare workers as a result of the COVID-19 pandemic: a cross-sectional study

COVID-19 healthcare workers (HCWs) require frequent handwashing and use of personal protective equipment (PPE) to prevent infection. However, evidence is emerging that these practices are causing adverse effects on their skin integrity. A single-centre, cross-sectional study of HCWs from an Irish hospital was undertaken to evaluate the degree of COVID-19-related irritant contact dermatitis (ICD) between April and May 2020. Of 270 participants surveyed, 223 (82.6%) reported symptoms of ICD. The hands were the most commonly affected site (76.47%) and the most frequently reported symptom was dry skin (75.37%). Nearly all (268; 99.26%) HCWs had increased hand-washing frequency, but 122 (45.35%) did not use emollients. In the ICD group, 24.7% cited a history of dermatitis compared with 4.3% of unaffected staff (P < 0.001). The ICD group recorded PPE usage for an average of 3.15 h compared with the non-ICD group at 1.97 h (P = 0.21). Promoting awareness of COVID-19-related ICD is vital to highlight prevention and treatment for frontline staff. Healthcare workers (HCWs) at the front line of the COVID-19 outbreak response are exposed to hazards that put them at risk of infection. Frequent hand hygiene and appropriate personal protective equipment (PPE) are recommended to prevent transmission of the virus. However, there is evidence to suggest that these practices are having a negative impact on skin health. HCWs in particular represent a high-risk group for developing occupational dermatitis, which can have a multitude of negative effects, including decreased compliance with proper PPE and adequate handwashing. We sought to evaluate the degree to which frontline staff members from a large tertiary hospital have been affected with irritant contact dermatitis (ICD) as a result of the COVID-19 pandemic
