A sensitive phosphate sensor has been prepared by constructing a solid membrane disk consisting of variable mixtures of silver phosphate, silver sulfide, and PTFE (Type 1 membrane) or silver phosphate, silver sulfide and nanotube (Type 2 membrane). The ternary membranes exhibit greater selectivity over the wide range of concentration. The membrane with the composition of 50.00% PTFE ; 41.66% Ag3PO4 and 8.33% Ag2S was selected as our preferred membrane. The membranes exhibited linear potential response in the concentration range of 1×10–1 to 1×10–5 M. Their detection limit is about 5×10–6 M. The membranes have a long lifetime and can be stored in air when they are not in use. The best performance for nanocomposite sensor was obtained with membrane of the following composition: 78.00% Ag3PO4 ; 20.00% Ag2S, and 2.00% carbon nanoparticles. The membrane had a slope of 32.6 mV toward HPO42- ions in the range between 1×10-1 and 1×10-5 M with a detection limit of 5.45×10–6 M. The proposed sensors were found to be applicable over a pH range between 3 and 7.

Background Agreement on the utility of imaging follow-up in patients with high-risk melanoma is lacking. A UK consensus statement recommends a surveillance schedule of CT or positron-emission tomography-CT and MRI brain (every 6 months for 3 years, then annually in years 4 and 5) as well as clinical examination for high-risk resected Stages II and III cutaneous melanoma. Our aim was to assess patterns of relapse and whether imaging surveillance could be of clinical benefit. Patients and methods A retrospective study of patients enrolled between July 2013 and June 2015 from three UK tertiary cancer centres followed-up according to this protocol was undertaken. We evaluated time-to-recurrence (TTR), recurrence-free survival (RFS), method of detection and characteristics of recurrence, treatment received and overall survival (OS). Results A total of 173 patients were included. Most (79%) had treated Stages IIIB and IIIC disease. With a median follow-up of 23.3 months, 82 patients (47%) had relapsed. Median TTR was 10.1 months and median RFS was 21.2 months. The majority of recurrences (66%) were asymptomatic and detected by scheduled surveillance scan. Fifty-six (68%) patients recurred with Stage IV disease, with a median OS of 25.3 months; 26 (31.7%) patients had a locoregional recurrence, median OS not reached (P=0.016). Patients who underwent surgery at recurrence for either Stage III (27%) or IV (18%) disease did not reach their median OS. The median OS for the 33 patients (40%) who received systemic therapy was 12.9 months. Conclusion Imaging appears to reliably detect subclinical disease and identify patients suitable for surgery, conferring favourable outcomes. The short median TTR provides rationale to intensify imaging schedule in the first year of surveillance. The poor OS of patients treated with systemic therapy probably reflects the relatively inferior treatment options during this time and requires further evaluation in the current era.

Aim To explore the experience of registered nurses in assessing pain in hip fracture in patients with dementia in the postoperative setting. Methods The study questionnaire contained 23 items mainly addressing demographic and social data, information about communication and pain assessment, attention and awareness of the health-care professionals on the ward and suggestions for improving nursing. Results The nurses claimed that they began their assessment of pain in patients with dementia first by observing the patient and making a visual assessment of pain, after which they began to communicate with these patients; majority of dementia patients with hip fractures displayed more facial expressions of pain than patients without dementia. All the nurses agreed that the more severe the patient's dementia was, the less clear the facial expressions and that this in turn made it difficult for the nurses to take care of such patients. Body language was the most common way the patients with dementia and hip fractures expressed their pain. Assessing the pain of a dementia patient with hip fracture and interpreting a non-verbally communicative patient was experienced as very difficult by all the nurses. Conclusion The nurses found that the fact that they had not attended any courses on dementia and pain assessment in those patients made their work more difficult; they need to know more and to have more information about those patients and their needs for a more comprehensive exchange of information between the hospital wards and the patients' care homes.

Objective Demonstration of idiopathic dilated cardiomyopathy with unusual flow, unpredictable clinical picture and complex therapy. Case report Patient A.P., female, 38 years old, had symptoms of dilated cardiomyopathy (with possible infectious myocarditis in the background) at age 17. After hospitalization for ten months and ten days, while waiting for heart transplantation (with threatening death outcome), without a clearly pronounced threatening arrhythmia, but with a low ejection fraction and a poor general condition, remission occurred. The therapy focused primarily on the treatment of heart failure, prevention of arrhythmia and thromboembolism. Normalization of the disease by improving the function of the left ventricle (expected in 16% of patients) occurred and lasted for 4 years, followed by an exacerbation of the disease that lasted for two years. In the next few years the patient was stable, had a first child with normal pregnancy. During the second trimester of the second pregnancy, there was an exacerbation (postpartum dilatation cardiomyopathy) lasting for couple of months. At the time of case report (May 2017), the patient is stable on therapy (ACE inhibitor, beta blocker, diuretics, If channel blocker), without limitation of physical capacity, mother of two children, unemployed. Conclusion The clinical course of dilated cardiomyopathy is extremely unpredictable and therapy is very complex and demanding.

High-throughput sequencing provides the means to determine the allelic decomposition for any gene of interest—the number of copies and the exact sequence content of each copy of a gene. Although many clinically and functionally important genes are highly polymorphic and have undergone structural alterations, no high-throughput sequencing data analysis tool has yet been designed to effectively solve the full allelic decomposition problem. Here we introduce a combinatorial optimization framework that successfully resolves this challenging problem, including for genes with structural alterations. We provide an associated computational tool Aldy that performs allelic decomposition of highly polymorphic, multi-copy genes through using whole or targeted genome sequencing data. For a large diverse sequencing data set, Aldy identifies multiple rare and novel alleles for several important pharmacogenes, significantly improving upon the accuracy and utility of current genotyping assays. As more data sets become available, we expect Aldy to become an essential component of genotyping toolkits. Many genes of functional and clinical significance are highly polymorphic and experience structural alterations. Here, Numanagić et al. develop Aldy, a computational tool for resolving the copy number and the sequence content of each copy of a gene by analyzing whole or targeted genome sequencing data.
