Breast cancer is the most common form of cancer among women. Around 6%–10% of initial breast cancers that a doctor diagnoses are metastatic. This number does not include breast cancers that progress to stage 4 after the initial diagnosis. Typically, oncologists call metastatic breast cancer stage 4 breast cancer. Some of these metastatic breast cancer cells may affect the lungs. It is essential that an oncologist confirms that the tumor in the lungs is secondary, meaning that it contains breast cancer cells. If there are no breast cancer cells present, the tumor could be a newly developed primary cancer.

A team of researchers led by the University of California San Diego has identified a genetic pathway that causes some individuals to develop an abnormal heart rhythm, or arrhythmia, after experiencing a heart attack. They have also identified a drug candidate that can block this pathway. Past studies have suggested that mutations in the 9p21 locus could be linked to these cardiovascular diseases, but there was no understanding of why and how. Now we have specific answers to these questions.

A new study about the side effects of antibiotic treatment reveals that it may dysregulate postpubertal skeletal development by interfering with gut bacteria. The trillions of bacteria living in our bodies are crucial for our health. They support the gastrointestinal and immune systems. They also help the body absorb nutrients from foods and supplements. People often call the "good" bacteria within us "commensal," because they live together in harmony without causing any harm. However, we often treat the "bad" microbes that cause disease using antibiotics.

Guselkumab (Tremfya) is now an option for routine NHS prescribing in patients with moderate to severe plaque psoriasis. Guselkumab is recommended by NICE as an option when the disease is severe and when the disease has not responded to other systemic therapies. Guselkumab is administered by sc injection at weeks 0 and 4 followed by a maintenance dose every 8 weeks.

According to a new study, vitamin D supplements have been found to reduce the risk of potentially fatal lung attacks in some chronic obstructive pulmonary disease (COPD) patients. The study analysis found that vitamin D supplements, given by mouth, reduced the rate of moderate/severe COPD exacerbations in patients with low vitamin D levels (less than 25 nmol per liter of blood or 10 nanograms per milliliter).

Experts discuss reasons for the increasing number of patients with Parkinson's disease and the challenges that need to be overcome to prevent and slow down a pandemic. The incidence of PD increases with age and the world's population is aging, as the number and proportion of individuals over 65 are rapidly growing. The combined result of these two factors is an unprecedented rise in the number of people with PD.

Researchers have uncovered new information about the underlying mechanisms for gastric cancer. They found that they could stop gastric cells dividing and growing by deleting a particular cell-surface receptor. They targeted a specific Fzd receptor called Fzd7, as this was identified the predominant Wnt receptor responsible for the function of stem cells in the stomach and intestine. They found that deletion of Fzd7 in gastric cells made these cells unable to respond to Wnt signals and they failed to divide and grow.

New research reveals that prescription opioids are commonly used long-term to treat pain in older patients with severe osteoarthritis. The analysis included 358,121 patients with an average age of 74 years. One in six patients used long-term prescription opioids for pain management in the year leading up to total joint replacement, with an average duration of approximately seven months.

According to findings published in Obesity, children and adolescents showed greater long-term reductions in BMI when their response in the first month was quick as compared to those who did not show a quick response. During the 6th month of the study, the initial responders showed a greater percentage of baseline BMI reduction. This research helps in concluding that early response is a good predictor in determining weight loss outcomes.

In a recent ruling, Judge issued a nationwide ban on the enforcement of two rules that would expand the ability for business entities to opt out of the provisions of the Patient Protection and Affordable Care Act (ACA) that require employers to offer insurance plans that include contraceptive coverage. The national injunction stops corporations from claiming religious or moral exemptions to birth control coverage.
