Biopharmaceuticals have established themselves as highly efficient medicines, and are still one of the fastest growing parts of the health-product industry. Unfortunately, the introduction of these promising new drugs went hand in hand with the creation of a black market for illegal and counterfeit biotechnology drugs. Particularly popular are the lyophilised peptides with a molecular weight of less than 5kDa. Most of them are meant for subcutaneous injection and are easily accessible via the internet. In recent years, different methods based on reversed phase liquid chromatography have been developed to detect and quantify these peptides...

The emergence in recent years of potentially dangerous new psychoactive substances (NPS) that are not under international control has led to the development of multi-analyte procedures for their unequivocal quantification. A fast ultra-performance liquid chromatography-tandem mass spectrometry method (UPLC-MS/MS), in combination with a sample pretreatment based on microextraction by packed sorbent (MEPS), was for the first time used in this work for the simultaneous determination of NPS in oral fluid. This matrix is an effective alternative to typical biological samples for drug control in substitution therapy programs, and also for the prevention and reduction of traffic accidents...

Kidney Disease: Improving Global Outcomes (KDIGO) engaged an evidence review team and convened a work group to produce a guideline to evaluate and manage candidates for living kidney donation. The evidence for most guideline recommendations is sparse and many "ungraded" expert consensus recommendations were made to guide the donor candidate evaluation and care before, during, and after donation. The guideline advocates for replacing decisions based on assessments of single risk factors in isolation with a comprehensive approach to risk assessment using the best available evidence...

Osteoporosis is related to more than 2 million fractures and $19 billion in healthcare costs each year (). A fragility fracture (FF) is a low-energy fracture of the distal radius, proximal humerus, ankle, or proximal femur (hip) from minimal trauma such as a fall from a standing height. In addition to cost, FFs often result in the loss of independence and productivity (). In 2015, our orthopaedic unit received the first certification ever awarded for FFs. Fragility fracture certification is a new certification demonstrating that a healthcare facility complies with national patient care standards and uses evidence-based practice guidelines to deliver quality outcomes...

: Chronic heart failure is a common clinical condition characterized by persistent excessive sympathetic nervous system activation. The derangement of the sympathetic activity has relevant implications for disease progression and patient survival. Aiming to positively impact patient outcome, autonomic nervous system modulatory therapies have been developed and tested in animal and clinical studies. As a general gross assumption, direct vagal stimulation and baroreflex activation are considered equivalent. This assumption does not take into account the fact that direct cervical vagal nerve stimulation involves activation of both afferent and efferent fibers innervating not only the heart, but the entire visceral system, leading to undesired responses to and from this compartment...

BACKGROUND: More than 1000 new patients present to the London Sarcoma Unit each year and between 5% and 10% require plastic surgery intervention. Advancements in radiotherapy and chemotherapy protocols combined with higher expectations for limb preservation has led to increased reconstructive challenges. Frequently, primary closure is achievable; however, larger tumors often require specialist reconstruction. STUDY DESIGN: A retrospective chart review of all referred patients from the London Sarcoma Unit requiring reconstruction between February 2006 and January 2015 was performed...

The number of computed tomography (CT) scans being done for children all over the world is on the rise ever since the advent of Multi-Detector CT (MDCT). However, CT is a potential source of harmful ionizing radiation, and children are more susceptible to its adverse effects. It is essential for the pediatrician as well as the radiologist to be aware of some important principles and guidelines, by following which, radiation exposure to the child can be minimized to the bare essential. It is important to have knowledge of the valid and justifiable indications of CT for the child, the correct technique of performing the scan, and the new technological innovations now available on modern scanners that help to minimize radiation dose...

BACKGROUND: Early studies have shown significant regional differences in the utilization of breast-conserving therapy (BCT) and mastectomy with reconstruction. It is expected that with the passage of time and the adoption of national treatment guidelines, these disparities would disappear. METHODS: Patients with non-metastatic breast cancer who underwent surgery between 2004 and 2013 were analyzed using the National Cancer Database (NCDB). Trends in BCT and reconstruction were evaluated and multivariate logistic regression performed...

INTRODUCTION: Endoscopic discectomy and fusions have been gaining popularity in the recent past and are noted to be safe for its application in elderly population. It involves ultra-small incision for discectomy followed by placement of percutaneous screws in awake patients. Treatment of advanced spinal pathology using endoscope-assisted techniques are challenging. Although not common with endoscopic approach, post-operative infection can be problematic as there are no established guidelines on its management...

The substantial increase in the burden of non-communicable diseases in general and osteoporosis in particular, necessitates the establishment of efficient and targeted diagnosis and treatment strategies. This chapter reviews and compares different tools for osteoporosis screening and diagnosis; it also provides an overview of different treatment guidelines adopted by countries worldwide. While access to dual-energy X-ray absorptiometry to measure bone mineral density (BMD) is limited in most areas in the world, the introduction of risk calculators that combine risk factors, with or without BMD, have resulted in a paradigm shift in osteoporosis screening and management...

BACKGROUND: Assessment of decisional capacity requires thorough clinical review of a patient's current psychiatric symptoms and cognitive processes. The assessment to determine the patient's capacity for self-management postdischarge is a different clinical concept from decisional capacity. OBJECTIVES: Standardized guidelines for capacity determinations (both for informed consent and for disposition) would be helpful to clinicians, patients, and their caregivers...

Dried matrix spot (DMS) technique as alternative sampling strategy, especially dried urine spots (DUS), might be an alternative for drug screening. So far only particular drugs or drug classes were covered in DMS screenings. Therefore, workup of DUS for a broad comprehensive library-based LC-MS(n) screening was developed. It consisted of enzymatic on-spot deconjugation followed by liquid extraction and LC-MS(n) analysis. This workup was compared to established urine precipitation (UP) and validated according to international guidelines for qualitative approaches, using exemplary compounds of several drug classes (antidepressants, benzodiazepines, cardiovascular drugs, neuroleptics, opioids, stimulants, etc...

Adenosine receptors (ARs) subtypes are involved in several physiological and pharmacological processes. Ligands able to selectively modulate one receptor subtype can delay or slow down the progression of diverse diseases. In this context, our research group focused its investigation into the discovery and development of novel, potent and selective ARs ligands based on coumarin scaffold. Therefore, a series 3-phenylcarboxamidocoumarins were synthesised and their affinity for the human ARs subtypes was screened by radioligand binding assays for A1 , A2A and A3 receptors and for A2B by adenylyl cyclase assay...

Parkinson's disease biomarkers are needed to increase diagnostic accuracy, to objectively monitor disease progression and to assess therapeutic efficacy as well as target engagement when evaluating novel drug and therapeutic strategies. This article summarizes perianalytical considerations for biomarker studies (based on immunoassays) in Parkinson's disease, with emphasis on quantifying total α-synuclein protein in biological fluids. Current knowledge and pitfalls are discussed, and selected perianalytical variables are presented systematically, including different temperature of sample collection and types of collection tubes, gradient sampling, the addition of detergent, aliquot volume, the freezing time, and the different thawing methods...

The extraction of coal and coal seam gas (CSG) will generate produced water that, if not adequately treated, will pollute surface and groundwater systems. In Australia, the discharge of produced water from coal mining and related activities is regulated by the state environment agency through a pollution licence. This licence sets the discharge limits for a range of analytes to protect the environment into which the produced water is discharged. This study reports on the impact of produced water from coal mine activities located within or discharging into high conservation environments, such as National Parks, in the outer region of Sydney, Australia...

Most treatment guidelines, including those from the American Diabetes Association/European Association for the Study of Diabetes and the International Diabetes Federation, suggest metformin be used as the first-line therapy after diet and exercise. This recommendation is based on the considerable body of evidence that has accumulated over the last 30 years, but it is also supported on clinical grounds based on metformin's affordability and tolerability. As such, metformin is the most commonly used oral antihyperglycemic agent in the U...
