INTRODUCTION: Due to interindividual variation in desmopressin response, non-severe haemophilia A patients require desmopressin testing prior to therapeutic treatment. However, adequate response or frequency of blood sampling is not standardised in international guidelines. Consequently, various definitions and blood sampling protocols are currently applied. Interestingly, sustainability of desmopressin response is not incorporated into these definitions. AIM: To study desmopressin response rates in a cohort of non-severe haemophilia A patients using currently accepted desmopressin response definitions...

Childhood-onset systemic lupus erythematosus (cSLE) is a rare, multisystem and potentially life-threatening autoimmune disorder with significant associated morbidity. Evidence-based guidelines are sparse and management is often based on clinical expertise. SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) was launched to optimise and disseminate management regimens for children and young adults with rheumatic diseases like cSLE. Here, we provide evidence-based recommendations for diagnosis and treatment of cSLE...

Expedition teams without accompanying medical professionals traveling overseas from the UK frequently carry medical kits containing prescription-only medicines (POMs). Access to safe, basic POMs whilst on expedition is important, as the quality and availability of medicines in-country may not be acceptable, and delay in treatment may be hazardous. At present, there is no published guidance relating to drug acquisition and administration in these situations. In the UK, a number of different practices are currently in use, with uncertainty and medicolegal concerns currently hampering safe and efficient provision of POMs on overseas expeditions...

BACKGROUND: The methodological quality and completeness of reporting of the systematic reviews (SRs) is fundamental to optimal implementation of evidence-based health care and the reduction of research waste. Methods exist to appraise SRs yet little is known about how they are used in SRs or where there are potential gaps in research best-practice guidance materials. The aims of this study are to identify reports assessing the methodological quality (MQ) and/or reporting quality (RQ) of a cohort of SRs and to assess their number, general characteristics, and approaches to 'quality' assessment over time...

CONTEXT: Hypertension is a common and costly risk factor for cardiovascular disease, but just over half of all adults with hypertension have their blood pressure controlled nationally. In Minneapolis-St Paul, Minnesota, the rate of hypertension control is approximately 70% despite a rate of hypertension control similar to the national average as recently as the first half of the 1990s. OBJECTIVE: The purposes of this study were to identify factors in Minneapolis-St Paul and state-level policies and programs in Minnesota that may have contributed to the more rapid increase in blood pressure control there than that in the rest of the nation and to identify factors that can potentially be replicated in other jurisdictions...

The objective of this study was to determine how simulated manual wheelchair pushing influences biomechanical loading to the lumbar spine and shoulders. 62 subjects performed simulated wheelchair pushing and turning in a laboratory. An electromyography-assisted biomechanical model was used to estimate spinal loads. Moments at the shoulder joint, external hand forces, and net turning torque were also assessed. Multiple linear regression techniques were employed to develop biomechanically-based wheelchair pushing guidelines relating resultant hand force or net torque to spinal load...

Metabolomics analysis of body fluids as well as cells is depended on many factors. While several well-accepted standard operating procedures for the analysis of body fluids are available, the NMR based quantitative analysis of cellular metabolites is less well standardized. Experimental designs depend on the cell type, the quenching protocol and the applied post-acquisition workflow. Here, we provide a tutorial for the quantitative description of the metabolic phenotype of mammalian cells using NMR spectroscopy...

A fast UHPLC-UV method was developed for the simultaneous analysis of Hydroxychloroquine, Minocycline and Doxycycline drugs from 100μL of human serum samples. Serum samples were extracted by liquid-liquid extraction and injected into a phenyl hexyl reverse phase column. Compounds were separated using a mobile phase linear gradient and monitored by UV detection at 343nm. Chloroquine and Oxytetracycline were used as internal standards. Lower and upper limits of quantifications, as well as the other levels of calibration, were validated with acceptable accuracy (<15% deviation) and precision (<15% coefficient of variation) according to the European Medicines Agency guidelines...

BACKGROUND: Abnormal respiratory rates are one of the first indicators of clinical deterioration in emergency department(ED) patients. Despite the importance of respiratory rate observations, this vital sign is often inaccurately recorded on ED observation charts, compromising patient safety. Concurrently, there is a paucity of research reporting why this phenomenon occurs. OBJECTIVE: To develop a substantive theory explaining ED registered nurses' reasoning when they miss or misreport respiratory rate observations...

Contemporary β-lactam antibiotic dosing is debatable in severely ill patients, since the occurrence of pathophysiological changes in critical illness can result in great inter-individual variability. Therapeutic drug monitoring (TDM) is a commonly used dosing strategy to optimize exposure and thereby minimize toxicity and maximize the efficacy. Currently, TDM of β-lactam antibiotics is rarely performed, due to poor availability in clinical practice. We describe an ultrafast Hydrophilic-Interaction Chromatography (HILIC) based UPLC-MS/MS method for the determination of amoxicillin, benzylpenicillin, cefotaxime, cefuroxime, ceftazidime, flucloxacillin, imipenem, meropenem and piperacillin in human plasma...

A sensitive and selective liquid chromatography-tandem mass spectrometric (LC-MS/MS) assay method has been developed and validated for the enantioselective determination of manidipine in human plasma using isotope labeled compounds as internal standards. After solid phase extraction, R-(-)-manidipine and S-(+)-manidipine were chromatographed on a Chiralpack IC-3 C18 column using a isocratic mobile phase composed of 2mM ammonium bicarbonate and acetonitrile (15:85, v/v). The precursor ion to product ion transitions for the enantiomers and internal standards were monitored in the multiple reaction monitoring and positive ionization mode using a API-4000 mass spectrometer...

Pancreatic ductal adenocarcinoma (PDAC) is currently the third most frequent form of malignancy. The role of biomarkers in the diagnostic and therapeutic strategy of cancer is constantly expanding. Translational research is already changing paradigms in tumours encompassing from early diagnosis to precision medicine in advanced disease. Nomenclature for molecular subtypes of tumours is gradually gaining acceptance and there are growing expectations it will further go from the bench to the bedside. However, the clinical relevance of biomarkers in PDAC is still far behind the relevance of biomarkers in other solid tumours...

INTRODUCTION: Respiratory tract infections (RTIs) are the most common reason for primary care (PC) consultations and for antibiotic prescribing and use. The majority of RTIs have a viral aetiology however, and antibiotic consumption is ineffective and unnecessary. Inappropriate antibiotic use contributes greatly to antibiotic resistance (ABR) leading to complications, increased adverse events, reconsultations and costs. Improving antibiotic consumption is thus crucial to containing ABR, which has become an urgent priority worldwide...

The voluntary, unpaid, altruistic blood donor is a cornerstone of current transfusion medicine. The complexity of medical and ethical issues related to blood donation and hemochromatosis has led to a large number of studies related to the safety of the hemochromatosis donor and the quality of the blood components produced from these donations. The issue of accepting persons with HC as blood donors is diverting, both in Europe and worldwide and without joint guidelines. A questionnaire-based study was performed and mailed to all 25 blood bank leaders in Norway...
