Strategies to Incorporate Left Atrial Appendage Occlusion Into Clinical Practice
The left atrial appendage (LAA) has been identified as a predominant source of thrombus formation leading to significant thromboembolic events in patients with nonvalvular atrial fibrillation. Medical therapy to eliminate thrombus formation in the LAA has been the standard of care for several decades, but mechanical approaches designed to exclude the LAA from the circulation have recently been developed. The largest body of randomized and nonrandomized data to date has been for the Watchman device (Boston Scientific, Natick, Massachusetts), which was recently approved by the Food and Drug Administration for selected patien...

Use of Robotics in Oncology Surgery.
Abstract Robotic surgery is a surgical procedure that adds a computer technology-enhanced device to the interaction between a surgeon and a patient during a surgical operation. This technology assumes a degree of control previously only reserved for the surgeon (Herron & Marohn, 2008). The surgeon sits at a console, typically in the operating room, directing and controlling the movements of one or more robotic arms. This technology has taken off in the United States during the past few years. Da Vinci® Surgical System, the leading robotic technology manufactured by Intuitive Surgical, Inc. (2014), has becom...

Should Pregnant Women be Included in Phase IV Clinical Drug Trials?
Relatively few drugs, especially those recently approved by the United States Food and Drug Administration (FDA), have published human pregnancy experience. Although all drugs contain animal reproduction data these are usually not predictive of human risk. Clinical trials in pregnant women are rarely conducted because of ethical and legal concerns and it may be many years before sufficient observational data are collected to guide clinical treatment decisions. Because many of these drugs will be used in pregnancy, human data are needed shortly after the drugs come to the market. (Source: American Journal of Obstetrics and Gynecology)

Clinical implications of patient-provider agreements in opioid prescribing.
Abstract In June, 2012 the United States Food and Drug Administration (FDA) developed a "blueprint" for prescriber education as a means of directing Certified Medical Education (CME) activities that included content which would meet the regulatory requirements of the class-wide, longacting/ extended-release (LA-ER) opioid Risk Evaluation Mitigation Strategies (REMS). Within the blueprint is the suggested adoption of Patient-Provider Agreements (PPAs) to be used in association with opioid prescribing, but, to our knowledge, there have been no reported evaluations of the role played by opioid-agent PPAs in clinical p...

PCSK9 Inhibitors and Neurocognitive Adverse Events: Exploring the FDA Directive and a Proposal for N -of-1 Trials
Abstract Proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors are a novel class of medications that greatly lower low-density lipoprotein cholesterol (LDL-C) by upregulating LDL receptor availability. In early 2014, the US Food and Drug Administration (FDA) directed developers of PCSK9 inhibitors to monitor neurocognitive adverse effects and consider neurocognitive testing in at least a subset of participants in ongoing late-stage trials. Available trial evidence indicates that neurocognitive adverse events may occur more commonly in individuals receiving an antibody to PCSK9, but these events are unco...

Endoscopic Treatment of Gastroesophageal Reflux Disease.
Abstract Multiple new endoluminal devices and therapies have been devised to create a more effective antireflux barrier in patients with gastroesophageal reflux disease (GERD). Most of these therapies have been abandoned, because they were ineffective and/or had significant adverse effects. However, there are currently two therapies (Stretta, EsophyX) that have US Food and Drug Administration approval and continue to be used in select patients with GERD.

Anything to Stay Alive: The Challenges of a Campaign for an Experimental Drug
Abstract Drug‐resistant tuberculosis (TB) has a high mortality rate. Most medicines used to treat it are poorly tested and have terrible side effects. Activists have campaigned for patients with drug‐resistant TB to have access to experimental drugs, particularly one called bedaquiline, before these have been approved by regulatory authorities such as the Food and Drug Administration (FDA) in the United States (US) and the Medicines Control Council (MCC) in South Africa. Some activists have also campaigned for bedaquiline to be approved by regulatory authorities before testing of the drug is completed. These campaigns ...

Current methods for the synthesis of homogeneous antibody-drug conjugates.
Abstract Development of efficient and safe cancer therapy is one of the major challenges of the modern medicine. Over the last few years antibody-drug conjugates (ADCs) have become a powerful tool in cancer treatment with two of them, Adcetris® (brentuximab vedotin) and Kadcyla® (ado-trastuzumab emtansine), having recently been approved by the Food and Drug Administration (FDA). Essentially, an ADC is a bioconjugate that comprises a monoclonal antibody that specifically binds tumor surface antigen and a highly potent drug, which is attached to the antibody via either cleavable or stable linker. This approach ensu...

Homozygous autosomal dominant hypercholesterolaemia: prevalence, diagnosis, and current and future treatment perspectives
Purpose of review: Homozygous autosomal dominant hypercholesterolemia (hoADH) is a rare genetic disorder caused by mutations in LDL receptor, apolipoprotein B, and/or proprotein convertase subtilisin-kexin type 9. Both the genetic mutations and the clinical phenotype vary largely among individual patients, but patients with hoADH are typically characterized by extremely elevated LDL-cholesterol (LDL-C) levels, and a very high-risk for premature cardiovascular disease. Current lipid-lowering therapies include bile acid sequestrants, statins, and ezetimibe. To further decrease LDL-C levels in hoADH, lipoprotein apheresis is ...

Daily left prefrontal repetitive transcranial magnetic stimulation for medication-resistant burning mouth syndrome
Burning mouth syndrome (BMS) is a persistent and chronic burning sensation in the mouth in the absence of any abnormal organic findings. The pathophysiology of BMS is unclear and its treatment is not fully established. Although antidepressant medication is commonly used for treatment, there are some medication-resistant patients, and a new treatment for medication-resistant BMS is needed. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technology approved by the US Food and Drug Administration (FDA) for the treatment of depression.

On Chlorofluorocarbon Bans and Inhaled Albuterol Prices
The competing concerns and interests of both individuals and society must be considered when establishing regulatory policy. In 2008, the US Food and Drug Administration (FDA) banned albuterol inhalers containing chlorofluorocarbons. This decision was questioned at the time because the chlorofluorocarbons emitted from inhalers have an insignificant effect on ozone and because of the anticipated costs of transitioning to hydrofluoroalkane inhalers for patients with respiratory disease. With the ban, generically manufactured chlorofluorocarbon inhalers were discontinued, leaving only branded hydrofluoroalkane inhalers availa...

Transdermal Buprenorphine, Opioid Rotation to Sublingual Buprenorphine, and the Avoidance of Precipitated Withdrawal: A Review of the Literature and Demonstration in Three Chronic Pain Patients Treated With Butrans
We present a case series of a novel method of sublingual buprenorphine introduction without an induction period, using the recently Food and Drug Administration-approved low-dose transdermal buprenorphine (Butrans; Purdue Pharma L.P.) as a bridge medication. In these cases, buprenorphine was started in opioid-dependent chronic noncancer pain patients who had taken short-acting opioid medications within hours of the initiation of the rotation. This method avoids the painful abstinence period and did not result in precipitated withdrawal or other significant adverse effects. (Source: American Journal of Therapeutics)

Abstract BackgroundFunctional gastrointestinal disorders (FGID) and inflammatory bowel diseases (IBD) are the most frequent pathologic conditions affecting the gastrointestinal (GI) tract and both significantly reduce patients’ quality of life. Recent studies suggest that guanylyl cyclase C (GC‐C) expressed in the GI tract constitutes a novel pharmacological target in the treatment of FGID and IBD. Endogenous GC‐C agonists – guanylin peptides: guanylin and uroguanylin, by the regulation of water and electrolyte transport, are involved in the maintenance of homeostasis in the intestines and integrity of the intestin...

The Development or Exacerbation of Eating Disorder Symptoms After Topiramate Initiation
The Food and Drug Administration recently approved topiramate for migraine prevention in adolescents. Given the well-established appetite-suppressant side effects of topiramate, as well as data suggesting a potential comorbidity between migraine and eating disorders, susceptible young migraine patients may be at a greater risk for the development or worsening of eating disorder symptoms with topiramate therapy. This case series comprises 7 adolescent patients in whom serious eating disorders developed or were exacerbated after the initiation of topiramate therapy. Clinical characteristics of these patients are highlighted....

Sufficiency of Information in 510(k) Summaries
To the Editor In their report on the lack of publicly available scientific evidence on the safety and effectiveness of implanted medical devices, Zuckerman and colleagues create a misleading impression of the evaluation of class II implants by the US Food and Drug Administration (FDA). Although the data are accurate, an understanding of the intricacies of device regulation is required to judge the agency’s performance. (Source: JAMA Internal Medicine)
