Medical Countermeasures for Radiation Exposure and Related Injuries: Characterization of Medicines, FDA-Approval Status and Inclusion into the Strategic National Stockpile
Abstract: World events over the past decade have highlighted the threat of nuclear terrorism as well as an urgent need to develop radiation countermeasures for acute radiation exposures and subsequent bodily injuries. An increased probability of radiological or nuclear incidents due to detonation of nuclear weapons by terrorists, sabotage of nuclear facilities, dispersal and exposure to radioactive materials, and accidents provides the basis for such enhanced radiation exposure risks for civilian populations. Although the search for suitable radiation countermeasures for radiation-associated injuries was initiated more tha...

The Times They Are A-Changin’: New Antibacterials for Skin and Skin Structure Infections
Abstract Twenty-one agents are approved by the US Food and Drug Administration (FDA) for the therapy of skin and soft tissue infections. Of these, the five newest agents, tedizolid, telavancin, oritavancin, dalbavancin, and ceftaroline, are active against and “non-inferior” to vancomycin against methicillin-resistant Staphylococcus aureus (MRSA). Oritavancin is indicated as a single-dose intravenous regimen, while dalbavancin is a two-dose intravenous regimen given 1 week apart. Telavancin has multiple mechanisms of action. A 6-day regimen of once-daily intravenous or oral dose of tedizolid was compared with 1...

Subcutaneous Implantable Cardioverter Defibrillator for Dialysis Patients: A Strategy to Reduce Central Vein Stenoses and Infections
In this report, we present 4 long-term hemodialysis patients treated successfully with an SICD. 3 patients received the device for primary prevention of sudden cardiac death (cardiomyopathy with low ejection fraction). The patient in the fourth case had a prolonged QT interval and received the device for secondary prevention. 3 patients had an arteriovenous fistula, whereas 1 patient was dialyzing with a tunneled dialysis catheter. Insertion of an SICD is a minimally invasive procedure. By virtue of leaving the venous system untouched, this approach might offer the advantage of reduced risk of central venous stenosis and i...

FDA issues final guidance on abuse‐deterrent opioids
On April 1, the Food and Drug Administration issued final guidance on the development of opioids with abuse‐deterrent properties. The FDA is encouraging manufacturers to develop drugs that work when taken as prescribed but deter misuse or abuse, including making it difficult to snort or inject the drugs. While deterrence is not “abuse‐proof,” the FDA said, it is a step toward balancing access to needed medications with the reduction of abuse.

Counterpoint: Dose Selection for rasH2 Mouse Carcinogenicity Studies.
Abstract Dose selection for the 6-month rasH2 mouse carcinogenicity studies depends heavily on the maximum tolerated dose (MTD) obtained from 1-month range-finding studies. A retrospective evaluation of range-finding studies and pivotal 6 month rasH2 mouse studies for 11 compounds demonstrated that the MTD based on at least a 10% decrease in body weight gain, mortality, and target organ toxicity in range-finding studies appropriately identified high doses for pivotal studies for 8 of 11 compounds. Two of the selected high doses were based on decreased body weight gain alone, while 7 were based on mortality at highe...

Nonhormonal strategies for hot flushes
A wide choice is available for women who do not wish to use estrogen. Paroxetine, fluoxetine, citalopram, venlafaxine and desvenlafaxine have been found to be effective in several studies. In 2013 the U.S. Food and Drug Administration approved paroxetine to treat moderate to severe hot flashes (vasomotor symptoms) associated with menopause. Clonidine is a centrally acting alpha-adrenoceptor agonist that was developed originally for the treatment of hypertension. It is licensed for the treatment of hot flushes in some countries.

Clinical Association Between Pharmacogenomics and Adverse Drug Reactions
This article updates our knowledge on how genetic polymorphisms of important genes alter the risk of ADR occurrence after an extensive literature search. To date, at least 244 pharmacogenes identified have been associated with ADRs of 176 clinically used drugs based on PharmGKB. At least 28 genes associated with the risk of ADRs have been listed by the Food and Drug Administration as pharmacogenomic biomarkers. With the availability of affordable and reliable testing tools, pharmacogenomics looks promising to predict, reduce, and minimize ADRs in selected populations. (Source: Drugs)

Emerging Options for Treating Hepatitis C Infection
Abstract Hepatitis C infection can cause chronic liver disease and liver carcinoma and can necessitate liver transplantation. Of the more than 3 million people infected with hepatitis C, more than two‐thirds were born between 1945 and 1965. Many individuals are unaware that they're infected, which can delay treatment and lead to disease progression. Once infection is diagnosed, typical treatment regimens can involve multiple medications and side effects that can make it challenging for some people to complete therapy. In October 2014 the U.S. Food and Drug Administration (FDA) approved Harvoni®, a fixed dose combination...

Electronic nicotine delivery systems: executive summary of a policy position paper from the american college of physicians.
Abstract Electronic nicotine delivery systems (ENDS), which include electronic cigarettes, or e-cigarettes, are growing in popularity, but their safety and efficacy as a smoking cessation aid are not well understood. Some argue that they have the potential to reduce tobacco-related morbidity and mortality and could be a useful tool for reducing tobacco-related harm. Others express concern that the health effects of ENDS use are unknown, that they may appeal to young people, and that they may encourage dual use of ENDS and traditional tobacco products. Although ENDS are a new and unregulated product, the U.S. Food a...

Shortage of Peritoneal Dialysis Solution and the Food and Drug Administration's Response.
Abstract Although the number of new drug shortages has been lower in recent years than in the past, severe shortages have occurred that have affected large numbers of patients. A new law entitled the Food and Drug Administration Safety and Innovation Act was enacted in July of 2012, which requires companies to notify the Food and Drug Administration of anticipated shortages. This notification requirement has allowed the Food and Drug Administration to work closely with manufacturers earlier to mitigate and, often, prevent shortages. However, not all shortages are able to be prevented, and the shortage of peritoneal...

Pharmacogenomics and personalized medicine: a review focused on their application in the Chinese population.
Abstract The field of pharmacogenomics was initiated in the 1950s and began to thrive after the completion of the human genome project 10 years ago. Thus far, more than 100 drug labels and clinical guidelines referring to pharmacogenomic biomarkers have been published, and several key pharmacogenomic markers for either drug safety or efficacy have been identified and subsequently adopted in clinical practice as pre-treatment genetic tests. However, a tremendous variation of genetic backgrounds exists between different ethnic groups. The application of pharmacogenomics in the Chinese population is still a long way o...

Special Commentary: Food and Drug Administration and American Academy of Ophthalmology Sponsored
The pace of medical research and development, estimated at $85 billion in research and development by industry plus the National Institutes of Health in 2010 alone, has brought about significant breakthroughs in medical care in the United States. Yet, there has been widespread concern that this investment has not yielded novel product applications to the Food and Drug Administration (FDA) or the diffusion of innovative medical technologies into the marketplace. The factors slowing medical innovation and keeping devices from the hands of clinicians in this country are complex. (Source: Ophthalmology)

[Comment] Pre-exposure prophylaxis works—it's time to deliver
The science is now clear: oral pre-exposure prophylaxis (PrEP) with a coformulation of tenofovir disoproxil fumarate and emtricitabine (Truvada) significantly reduces the risk of HIV infection among individuals at high risk of HIV infection. The news that PrEP has shown consistent efficacy among those who take it as prescribed should be a cause for celebration, and galvanise action to ensure access to PrEP for those who could benefit the most. But almost 3 years since the US Food and Drug Administration approved tenofovir–emtricitabine for PrEP,1 little is being done on implementation. (Source: LANCET)

Rapid analysis of ractopamine in pig tissues by dummy-template imprinted solid-phase extraction coupling with surface-enhanced Raman spectroscopy.
Abstract Ritodrine has similar skeleton structure to ractopamine and it was selected as the dummy-template molecule to synthesize the molecular imprinted polymers (MIPs). The MIPs exhibited better selectivity to ractopamine than to the dummy-template molecule: the imprint factor for ractopamine was 8.9, while 7.6 for ritodrine. The MIPs were used as sorbents in solid-phase extraction for selective enrichment of ractopamine, and some key parameters were optimized. After that, a rapid surface-enhanced Raman spectroscopy method was developed for analysis of ractopamine and isoxuprine in pig tissue samples. Under the o...

Warfarin has been the centre of oral anticoagulant therapy for over 60 years. Recent development of new oral anticoagulants (NOACs) has provided a safe and effective alternative for stroke prevention in patients with atrial fibrillation and for prevention of venous thromboembolism. Determination of their use in acute coronary syndrome has been hampered by increases in bleeding events in most large trials, especially when used with antiplatelet therapy. NOACs have equal or superior efficacy and safety profiles compared to warfarin, fewer drug interactions; no dietary restrictions; predictable responses that eliminates moni...

Transfer of Natalizumab into Breast Milk in a Mother with Multiple Sclerosis
Natalizumab (Tysabri) is a recombinant humanized antibody to α4-integrin that is approved by the Food and Drug Administration for the treatment of multiple sclerosis (MS) and Crohn disease. This is a case report of a 28-year-old woman with MS who was taking natalizumab (300 mg intravenously infused over 1 hour every 4 weeks) while breastfeeding her 11.5-month-old daughter 3 times a day. Breast milk samples were collected over a 50-day period after the patient’s first drug infusion. The average concentration of natalizumab was 0.93 µg/mL/d, and the relative infant dose was 1.74% of the weight-adjusted mate...

Pregnancy outcomes in patients exposed to interferon beta-1b
Introduction Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system that is usually diagnosed in a patient's 20s or 30s and is more common in women than in men.1 Given this typical patient profile, many patients with MS are women in their reproductive years. None of the currently approved disease-modifying therapies (DMTs) for patients with MS are recommended for use during pregnancy. Furthermore, all of these medications have been given a pregnancy category B, C, D or X by the US Food and Drug Administration, indicating that in the best case (category B), animal studies have fa...

Immunotherapy in Melanoma: Recent Advances and Promising New Therapies
The incidence and mortality of melanoma are on the rise. Historically, patients diagnosed with metastatic melanoma were faced with a grim prognosis, with survival rates of 15% at 5 years. Prior to 2011, no drug or therapeutic regimen had been shown to improve overall survival (OS) in metastatic melanoma. Chemotherapeutic agents, such as dacarbazine or temozolomide, are often given to patients for palliative purposes; high-dose interleukin 2 and biochemotherapy are immunotherapeutic options that could be offered to patients with a good performance status at specialized centers. Neither has been shown to impact OS, but durab...

Liraglutide Promotes Cortical Neurite Outgrowth via the MEK-ERK Pathway.
Abstract Liraglutide is the glucagon-like peptide-1 (GLP-1) synthetic form which has been approved by the US Food and Drug Administration to be released onto the market. The metabolic benefits of incretin hormone as an anti-diabetic agent are widely recognized, but its potential extra-pancreatic effects of GLP-1 analog (liraglutide) in the central nerve system are less well known. To this purpose, we used immunofluorescence method to examine the effect of liraglutide on neurite outgrowth in primary cortical neuron culture by measuring neurite length and confirmed the promotion effect. Then, we investigated the pot...

Sequences and combinations of multifaceted therapy in advanced prostate cancer
This report of the Enzalutamide in men with chemotherapy-naive metastatic prostate cancer (PREVAIL) trial led to the Food and Drug Administration approval of this agent. Novel agents such as cabozantinib and custirsen that had shown promising results in phase II trials revealed disappointing results in the phase III setting. The breakthrough report, of the ability of the androgen receptor splice variant mutation, detected in circulating tumor cells, to predict lack of response to abiraterone or enzalutamide, and the remarkable responses of poly(ADP-ribose) polymerase inhibitors in prostate cancer with breast cancer genes 1...

Efficacy of hemcon dental dressing in reducing postsurgical complications following mandibular third molar extractions
The surgical removal of impacted mandibular third molars results in tissue trauma, inflammation, and bleeding and is most often accompanied by moderate to severe pain. The HemCon Bandage is a U.S. Food and Drug Administration-cleared chitosan-based flat bandage that controls severe arterial bleeding from traumatic injuries. HemCon dental dressing material (HemCon Medical Technologies, Portland, OR, USA) improves hemostasis and stabilizes clots in anticoagulated patients. The dressing becomes adherent when in contact with the oral wound environment and provides a protective layer. (Source: Oral Surgery, Oral Medicine, Oral ...
