Tacrolimus exhibits inter-patient pharmacokinetic variability attributed to CYP3A5 isoenzymes and the efflux transporter, P-glycoprotein. Most black renal transplant recipients require higher tacrolimus doses compared to whites to achieve similar troughs when race-adjusted recommendations are used. An established guideline provides tacrolimus genotype dosing recommendations based on CYP3A5*1(W/T) and loss of protein function variants: CYP3A5*3 (rs776746), CYP3A5*6 (rs10264272), CYP3A5*7 (rs41303343) and may provide more comprehensive race-adjusted dosing recommendations...

Introduction: Vesicoureteral reflux (VUR) is one of the most common ailments in children. Evidence-based guidelines recommend conservative treatment in children with VUR, followed by endoscopic surgery in those with breakthrough febrile urinary tract infections (UTIs). Despite this fact, the management of VUR is still controversial. Our objective is to evaluate the conservative strategy in children with primary VUR in terms of renal function and scarring, and identify factors associated with poor prognosis in those children...

Haemorrhage remains a leading cause of maternal death. We conducted an audit to identify strategies to improve the management at our local NHS Trust. A data collection form was based on our local guideline. A coded database search was conducted for all deliveries where the estimated blood loss was ≥2000 ml (from June 1 2015 to December 31 2015), returning 68 search results (13.7/1000 births). Fifty-six records were included. Poor compliance (<75%) was seen in some key areas including the major obstetric haemorrhage (MOH) call activation (52%), the presence of an anaesthetic consultant (63%) and tranexamic acid administration (46%)...

In the past 50 years, Cannabis sativa (C. sativa) has gone from a substance essentially prohibited worldwide to one that is gaining acceptance both culturally and legally in many countries for medicinal and recreational use. As additional jurisdictions legalize Cannabis products and the variety and complexity of these products surpass the classical dried plant material, appropriate methods for measuring the biologically active constituents is paramount to ensure safety and regulatory compliance. While there are numerous active compounds in C...

REVIEW
Claudio Galli, Paul Julicher, Mario Plebani
The diagnosis of hepatitis C virus (HCV) infection has been traditionally based on the detection of the host antibody response. Although antibody assays are available in different formats and are fairly accurate, they cannot distinguish between an ongoing infection with HCV replicative activity and a past infection where HCV has been cleared, spontaneously or after a successful therapy. As a chronic infection is mostly asymptomatic until the late clinical stages, there is a compelling need to detect active HCV infection by simple and reproducible methods...

Gas-phase simulations of nitric acid-amine chemistry suggest that the fundamental acid-base interaction between HNO3 and NH3 results in a variety of HNO3-NH3-based complexes, such as (HNO3)3·(NH3)2, (HNO3)3·(NH3)3, and (HNO3)4·(NH3)3, that can be formed. The formation of these complexes in the gas phase follow different growth mechanisms under different relative humidity conditions. On the other hand, at the air-water interface, Born-Oppenheimer molecular dynamics simulations suggest that the formation of the fundamental NO3-(R1)(R2)NH2+ [for NH3, R1 = R2 = H; CH3NH2, R1 = H, R2 = CH3; and (CH3)2NH, R1 = R2 = CH3] ion pairs require the formation of the HNO3(R1)(R2)NH complexes in the gas-phase prior to their adsorption on the water surface...
