‘Normal’ bacteria vital for keeping intestinal lining intact

The research involved the intestinal microbiome, which contains some 100 trillion bacteria. The role of these microorganisms in promoting or preventing disease is a major emerging field of study. Einstein scientists found that absorption of a specific bacterial byproduct is crucial for maintaining the integrity of the intestinal epithelium — the single-cell layer responsible for keeping intestinal bacteria and their toxins inside the gut and away from the rest of the body…

Why we should vaccinate boys against HPV as well as girls

Gillian Prue, from the School of Nursing and Midwifery at Queen’s University of Belfast, says that the human papillomavirus (HPV) infection is common in men and can lead to genital warts and the development of some head and neck, anal or penile cancers. She says incidence of this has increased in the past two decades with HPV causing 5% of all human cancers. …

Incomplete HPV vaccination may offer some protection

Researchers from Boston University School of Public Health and School of Medicine conducted a cross-sectional study of 235 women age 21 to 30 undergoing routine cervical cytology testing. HPV status and demographic and behavioral characteristics were self-reported and verified with electronic medical records. “Although data clearly indicate better immune responses and vaccine efficacy against both genital warts and cervical dysplasia when vaccination occurs before age 14, this study suggests that HPV vaccination may be effective in reducing abnormal Pap test results even after sexual debut,” explained co-author Rebecca Perkins, MD, MSc, assistant professor of Obstetrics and Gynecology at Boston University School of Medicine and a gynecologist at Boston Medical Center. At the time of the study, 41 percent had received at least one HPV vaccination; 97 percent of women were vaccinated after sexual debut. …

Starving pancreatic cancer before it has a chance to feast

Pancreatic cancer and other cancers can only thrive, grow and spread if they have nutrients from blood, just like other tissues in our bodies. Cancer cells and tumors at first rely on nearby blood vessels to get what they need to survive, but, as tumors grow, they need to form new vessels. These vessels differ from those in regular tissue, Sushanta explained, which is part of the reason cancer can be so difficult to treat. …

Adding element to standard treatment in post-gemcitabine metastatic pancreatic cancer improves survival

“Patients with metastatic pancreatic cancer or pancreatic cancer in general have very limited options,” said study author Andrea Wang-Gillam, assistant professor in the Division of Oncology at Washington University in St. Louis, USA. “These patients just simply don’t do well. …

Ovarian cancer treatment discovered by researchers

Trebananib (formally known as AMG 386; Amgen) is a first-in-class peptide-Fc fusion protein (or peptibody) that targets angiogenesis (the growth of new blood vessels into cancerous tumors) by inhibiting the binding of both angiopoietin 1 and 2 to the Tie2 receptor. This is very different mechanism of action than other agents that also effect angiogenesis by inhibiting vascular endothelial growth factor (VEGF) such as bevacizumab (Avastin; Genentech). Trebananib does not increase the risks of hypertension (high blood pressure) and bowel perforation like bevaciuzmab, but still has a similar impact on tumor shrinkage and delaying cancer progression…

Synthetic triterpenoids show promise in preventing colitis-associated colon cancer

The molecules, known as synthetic triterpenoids, appear to achieve their positive effect in two ways. First, they impede inflammation, often a flashpoint that contributes to the development of colon cancer. Second, they increase 15-hydroxyprostaglandin dehydrogenase (15-PGDH), a gene product that is known at high levels to protect against colon cancer. …

More than two-thirds of healthy Americans are infected with human papilloma viruses

Researchers say that while most of the viral strains so far appear to be harmless and can remain dormant for years, their overwhelming presence suggests a delicate balancing act for HPV infection in the body, in which many viral strains keep each other in check, preventing other strains from spreading out of control. Although infection is increasingly known to happen through skin-to-skin contact, HPV remains the most common sexually transmitted infection in the United States. It is so common that experts estimate nearly all men and women contract some strain of it during their lives. …
