BACKGROUND: Underage college students who obtain and use false identification (fake ID) are at risk for negative outcomes. However, it is currently unclear how uniquely the fake ID itself serves as a vehicle to subsequent harm (i.e., the "fake ID effect") over and above general and trait-related risk factors (e.g., deviant peers, low self-control). METHODS: To investigate whether the "fake ID effect" would hold after accounting for phenotypic risk, we utilized propensity score matching (PSM) in a cross-sectional sample of 1,454 students, and a longitudinal replication sample of 3,720 undergraduates...

The prognostic role of Extracellular matrix metalloproteinase inducer (EMMPRIN/ CD147) in gastrointestinal cancer remains controversial. We systematically reviewed the evidence of assessment of CD147 expression in gastrointestinal cancer to help clarify this issue. Pubmed, Embase, Cochrane Library and Web of Science databases were searched to identify eligible studies to evaluate the association of CD147 expression and disease-free and overall survival of gastrointestinal cancer. Hazard ratios (HRs) were pooled to estimate the effect...

INTRODUCTION: With the intent of improving transparency in clinical research, the International Committee of Medical Journal Editors (ICMJE) established guidelines in 2005 regarding prospective clinical trial registration. This action worked to address bias related to selective outcome reporting in the medical literature. The objective of this study was to assess and characterize the quality of registration of clinical trials appearing in shoulder arthroplasty-related medical journals...

INTRODUCTION: Of the two million new HIV infections in adults in 2014, 70% occurred in sub-Saharan Africa. Several African countries have already approved guidelines for pre-exposure prophylaxis (PrEP) for individuals at substantial risk of HIV as part of combination HIV prevention but key questions remain about how to identify and deliver PrEP to those at greatest need. Throughout the continent, individuals in sero-discordant relationships, and members of key populations (sex workers, men who have sex with men (MSM), transgender women and injection drug users) are likely to benefit from the availability of PrEP...

BACKGROUND: Most of the chemical substances which emerge out as potential drug candidates (Active Pharmaceutical Ingredients) are either weak acids or weak bases. Poor aqueous solubility of these drug substances is a common concern. Several R&D centers are focused on developing suitable, economic, simpler and more feasible solubility enhancement techniques for increasing the solubility and thereby bioavailability of such drug substances. Nanocrystals is one of the preferred approaches for solubility enhancement in last few decades...

In the last few years, the concepts of disease elimination and eradication have again gained consideration from the global health community, with Guinea worm disease (dracunculiasis) on track to become the first parasitic disease to be eradicated. Given the many complex and interlinking issues involved in committing to a disease eradication initiative, such commitments must be based on a solid assessment of a broad range of factors. In this chapter, we discuss the value and implications of undertaking a systematic and fact-based analysis of the overall situation prior to embarking on an elimination or eradication programme...

Management of hypertension in diabetes is critical for reducing cardiovascular mortality and morbidity. Dietary approaches for controlling high blood pressure have historically focused on sodium. Thus, many guidelines recommend that patients with type 2 diabetes reduce high sodium intake. Nonetheless, the potential benefits of sodium reduction are debatable. The kidney has a crucial role in glucose filtration and reabsorption in addition to its regulation of fluid and electrolyte homeostasis. A key factor linking sodium uptake and glucose transport is the sodium-glucose cotransporter 2 (SGLT2) in renal proximal tubular cells...

Catheter-based renal sympathetic denervation (RDN) has opened the new world in the treatment of resistant or refractory hypertension. However, SYMPLICITY HTN-3, 2:1 randomization, blinded and sham-controlled study did not show a significant reduction of systolic blood pressure (BP) in patients with resistant hypertension 6 months after RDN as compared with a sham control. After that, substudy investigating the predictors of BP responses in SYMPLICITY HTN-3 trial was reported; racial difference and optimal medical treatment were issued for the optimal denervation therapy...

Arterial pulsation which had long been studied for estimation of blood pressure or mean blood pressure was replaced by the measurement of systolic and diastolic blood pressure using Korotkoff sound detected by stethoscope in the beginning of the previous century. In the meantime, vast of modern knowledge of human hypertension from epidemiology to randomized clinical trial had been built on the Korotkoff sound and stethoscope methodology. Hypertension is very special clinical entity in terms of the diagnosis is solely dependent on the manual blood pressure measurement by a physician or nurse...

The J curve hypothesis propose that the relation between blood pressure and risk for cardiovascular events is non-linear. Instead of a decreased risk with lower blood pressure, the risk increases at lower blood pressures. This issue has been discussed for many years, and is still a hot topic. The debates have most often had its origin in the question about how far blood pressure should be lowered with antihypertensive drugs.One one hand, we know that many patients with hypertension is not treated to targets according to guidelines and that this contributes to the high risk for cardiovascular diseases in patients with hypertension...

Hypertension is the main risk factor for morbidity and mortality in the world. In Sub-Saharan Africa, hypertension, previously almost unknown, is now a major risk factor. A paper recently published showed that mean systolic blood pressure is higher in all regions of Africa compared with other parts of the world, and, most important and contrary to what is happening in the rest of the world, it is increasing in the last years. Another important issue that characterises hypertension in Africa is its extremely low level of awareness and consequently low level of control...

Over 3000 delegates attended the 26st International Congress of the Transplantation Society in Hong Kong, which marked the 50th anniversary of the society. In his presidential address, Professor Phil O'Connell from the Westmead Hospital in Sydney, Australia, commented that a major challenge for the future is improving long-term outcomes after solid organ transplantation. He highlighted that 40% of transplanted organs are lost within 10 years, and that a high proportion of patients suffer from immunosuppression-related side effects...

PURPOSE OF REVIEW: Biological agents have been a treatment option for many chronic immune-mediated diseases as well as oncological conditions. The issue of infusion reactions is of particular importance and at least in some cases related to the immunogenicity of these drugs with the production of antidrug antibodies. Infectious diseases are a well described side-effect of certain biological agents, even if, at least regarding the biological agents used for the treatment of allergic diseases and immune-mediated diseases, the risk has been reduced...

The cancer stem cell (CSC) model suggests that a small subset of cancer cells possess stem cell properties and plays a crucial role in tumor initiation, metastasis and resistance to anticancer therapy. Exploration of the specific therapies targeting at CSCs has been a crucial issue in antitumor research. Gastric cancer (GC) cells often exist in an ischemic microenvironment with acidic conditions in vivo, thus maintenance of cellular pH homeostasis is important for the survival and function of GC cells. Proton pump inhibitors (PPIs) may prevent intracellular proton extrusions which consequently reduce cancer cell survival under acidic conditions...

BRAF inhibitor (BRAFi) therapy for melanoma patients harboring the V600E mutation is initially highly effective, but almost all patients relapse within a few months. Understanding the molecular mechanisms underpinning BRAFi-based therapy is therefore an important issue. Here we identified a previously unsuspected mechanism of BRAFi resistance driven by elevated Hedgehog (Hh) pathway activation that is observed in a cohort of melanoma patients after vemurafenib treatment. Specifically, we demonstrate that melanoma cell lines, with acquired in vitro-induced vemurafenib resistance, show increased levels of glioma-associated oncogene homolog 1 and 2 (GLI1/GLI2) compared with naïve cells...

BACKGROUND: A number of methods exist for the risk assessment of hospital inpatients to determine the likelihood of patients experiencing drug-related problems (DRPs), including manual review of a patient's medication (medication reviews) and more complex electronic assessment using decision support alerts in electronic prescribing systems. A systematic review was conducted to determine the evidence base for potential risks associated with adult hospital inpatients that could not only lead to medication-related issues but might also be directly associated with pharmacist intervention...

BACKGROUND: Gancyclovir-resistant (GanR) cytomegalovirus (CMV) remains an issue, especially in solid organ transplant (SOT) recipients. Some mutations in UL54 and UL97 confer this resistance. Long-lasting high-dose drug exposure, high viral load, together with lack of sufficient compliance with treatment may account for these mutations. The aim of this study was to detect UL97 and UL54 putative mutations conferring ganciclovir-resistance in renal organ transplant recipients with high CMV load...

In Taiwan, injecting drug use has been the main route of human immunodeficiency virus (HIV) transmission since 2005, with hepatitis B virus (HBV) and hepatitis D virus (HDV) also having similar transmission routes. This has now become an important public health issue. The aim of this study is to explore the conditions of HDV infections between injecting drug users (IDUs) with and without HIV infection in Southern Taiwan. In this study, 87 IDUs were enrolled, including 27 anti-HDV seronegative IDUs and 60 anti-HDV seropositive IDUs, and the results of their liver function tests, CD4 cell counts, and anti-HIV and HIV RNA levels were analyzed...

Inclusion of a microdose of (14)C-labeled drug in the first-in-man study of new investigational drugs and subsequent analysis by accelerator mass spectrometry has become an integrated part of drug development at Lundbeck. It has been found to be highly informative with regards to investigations of the routes and rates of excretion of the drug and the human metabolite profiles according to MIST guidance, and also when additional metabolism related issues needed to be addressed. In the first-in-man study with the NCE Lu AF09535, contrary to anticipated, surprisingly low exposure was observed when measuring the parent compound using conventional bioanalysis...
