Why medical research keeps changing its mind
Did you ever wonder why medical research seems to flip-flop so often? Eggs used to be terrible for your health; now they’re not so bad. Stomach ulcers were thought to be due to stress and a “type A personality” but that’s been disproven. I was taught that every postmenopausal woman should take hormone replacement therapy to prevent heart disease and bone loss; now it’s considered way too risky. It can make you question every bit of medical news you hear. But maybe that’s not such a bad thing. Questioning what you read or hear is reasonable. And maybe medical reversals — when new research leads to a complete turnaround regarding a widespread medical practice or treatment — are not as common as they seem. Perhaps they get more attention than they deserve and drown out the consistent and “non-reversed” medical research that’s out there. For example, it seems unlikely that the health benefits of regular exercise, smoking cessation, or maintaining a healthy weight will ever be reversed. A new study examines medical reversals A remarkable new study explored the phenomenon of medical reversals to determine how common they are, and to identify what types of conditions were most involved. Researchers collected more than 3,000 randomized controlled trials; these are considered the most reliable types of research because they randomly assign otherwise similar study subjects to different treatment groups and try to account...

ConclusionOur analysis provided strong evidence to indicate a causal relationship between WC and increased risk of CHD.
ConclusionNEAT1 upregulateIGF2 expression through absorbing miR ‐185‐5p to enhances the migration and invasion of colon cancer cells.
ConclusionOur results suggest that the combination of altered expression of genes involved in signaling pathways of immune response and apoptosis control may contribute directly to the main characteristics observed in BS, such as recurrent infections, growth failure, and high risk of cancer. Transcriptome studies of other instability syndromes could allow a more accurate analysis of the relevant gene interactions associated with the destabilization of the genome. This is a first description of the profile of differential gene expression related to immunological aspects detected in patients with BS by RNA ‐seq.
Helicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Aging ‐associated risk factors should be considered. Future studies, related to aging andH. pylori infection with extragastric disease can help to provide vivid evidences. AbstractHelicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Elderly people tend to resist eradication treatment and worsening of infection can lead to several gastric and non ‐gastric pathologies. Aging‐associated cellular and molecular alteration can increase the ris...
ConclusionIn summary, the above results indicate thatXIST promotes colorectal cancer tumorigenesis by regulating miR ‐93‐5p/HIF ‐1A/AXL signaling pathway, which will supply a novel perspective to diagnose and treat colorectal cancer disease.

ConclusionChronic inflammation in the dorsolateral prostate of rats dosed with EB, T and E resulted in deregulated expression in a set of microRNAs whose target genes were related to tumor growth or abnormal proliferation. Our findings suggest the identified microRNAs and their target genes the potential use as biomarkers to predict prostate cancer development. Validation using human samples is warranted.
Discussion and conclusionsA schema showing the time from initiation of therapy at which specific antineoplastic agents can cause significant levels of genetic damage in conceptuses and live offspring was developed. The estimates and methods for computing the level of such risk from an individual patient's treatment regimen will enable patients and counselors to make informed decisions on the use of spermatozoa or continuation of a pregnancy.
