Committee Opinion No. 704 Summary: Human Papillomavirus Vaccination.
Authors: Abstract Human papillomavirus (HPV) is associated with anogenital cancer (including cervical, vaginal, vulvar, penile, and anal), oropharyngeal cancer, and genital warts. The HPV vaccination significantly reduces the incidence of anogenital cancer and genital warts. Despite the benefits of HPV vaccines, only 41.9% of girls in the recommended age group, and only 28.1% of males in the recommended age group have received all recom-mended doses. Compared with many other countries, HPV vaccination rates in the United States are unacceptably low. The U.S. Food and Drug Administration has approved three vaccine...

Emerging Treatments in Eating Disorders
AbstractEating disorders (EDs), including anorexia nervosa, bulimia nervosa, and binge-eating disorder, constitute a class of common and deadly psychiatric disorders. While numerous studies in humans highlight the important role of neurobiological alterations in the development of ED-related behaviors, the precise neural substrate that mediates this risk is unknown. Historically, pharmacological interventions have played a limited role in the treatment of eating disorders, typically providing symptomatic relief of comorbid psychiatric issues, like depression and anxiety, in support of the standard nutritional and psycholog...

Pharmacokinetic, Pharmacodynamic, and Antihypertensive Effects of the Neprilysin Inhibitor LCZ-696: Sacubitril/Valsartan
LCZ-696: sacubitril/Valsartan is a dual-acting molecule consisting of the angiotensin II (Ang II) receptor blocker (ARB) valsartan and the neprisylin (neutral endopeptidase, NEP) inhibitor AHU-377 with significant beneficial effects in patients with hypertension and heart failure (HF). Several recent studies have demonstrated a higher effectiveness of LCZ-696 compared to valsartan in the treatment of hypertension and HF. The rationale for the development and the Food and Drug Administration (FDA) approval of LCZ-696 was based on the concept of an additive effect of the angiotensin II receptor blocker valsartan and the NEP ...

We set out to determine whether defined failure mode (DFM; collagen plug, device handle, footplate, and/or sheath) at index deployment vs an undefined failure mode (UFM) had differing outcomes in terms adverse patient consequences and/or returned devices (Table).

The Development and Use of Janus Kinase 2 Inhibitors for the Treatment of Myeloproliferative Neoplasms
Following the discovery of the JAK2V617F mutation, Janus kinase (JAK) 2 inhibitors were developed as rationally designed therapy in myeloproliferative neoplasms (MPNs). Although JAK2 inhibitors have clinical efficacy in MPN, they are not clonally selective for the JAK2V617F-mutant cells. Because activated JAK-signal transducer and activator of transcription (STAT) signaling is a common feature of MPN, JAK2 inhibitors are efficacious regardless of the specific MPN phenotypic driver mutation. The Food and Drug Administration approved the JAK1/JAK2 inhibitor, ruxolitinib, for the treatment of myelofibrosis and polycythemia ve...

Considering the Role of the Laparoscopic Adjustable Gastric Band
Bariatric surgery as a discipline has evolved dramatically since the first procedure intended to induce weight loss was performed following World War II. In the past 60 years, procedures have come and gone, including the jejunalileal bypass, the horizontal gastroplasty, and the vertical-banded gastroplasty. The laparoscopic adjustable gastric band (LAGB) enjoyed a significant growth in popularity over the first 5 years following its approval from the US Food and Drug Administration. In the past 5 years, the use of the LAGB has seen a precipitous decline. In the United States, we may be close to saying goodbye to the LAGB. ...

Injectable and topical neurotoxins in dermatology
Botulinum toxin is a potentially deadly anaerobic bacterial toxin that acts by inhibiting release of acetylcholine at the neuromuscular junction, thereby inhibiting contraction of the exposed striated muscle. There are currently 4 botulinum toxin preparations approved by the US Food and Drug Administration (FDA): onabotulinumtoxin, abobotulinumtoxin, incobotulinumtoxin and rimabotulinumtoxin. While significant overlap exists, each product has unique properties and specifications, including dosing, diffusion, and storage. (Source: Journal of the American Academy of Dermatology)

7,8-hydroxy-2'-deoxyguanosine/2'-deoxiguanosine ratio determined in hydrolysates of brain DNA by ultrachromatrography coupled to tandem mass spectrometry.
bar J Abstract 7,8-hydroxy-2'-deoxyguanosine (8-OHdG) is an abundant DNA lesion formed by oxidation of the nucleoside 2'-deoxyguanosine (2-dG) and one of the most studied and accepted oxidative stress biomarkers. 8-OHdG has a strong carcinogenic potential, and prolonged oxidative stress heightens pathological conditions and especially cancer risk. Our aim was to develop, validate and apply a reliable method to assess DNA oxidation in genomic cellular DNA of sensible target organs such as brain. A procedure to isolate and digest the DNA of brain tissue properly for further detection of 8-OHdG and 2-dG by Ultra Perf...
