Diagnosis is the act or process of identifying or determining the nature and cause of a disease or injury through evaluation of patient history, examination, and review of laboratory data.
Researchers discover 5 inherited genetic variants linked to the most lethal prostate cancers – An international team of researchers led by Fred Hutchinson Cancer Research Center has identified five inherited genetic variants that are strongly associated with aggressive, lethal prostate cancer.
Pitt cancer researchers find key oncoprotein in Merkel cell carcinoma – Knocking out a viral protein called “small tumor protein,” or sT, stopped the cancer cells from replicating, revealed by researchers in a recent study.
Prescriptions for Antidepressants Increasing among Individuals with no Psychiatric Diagnosis – In Americans, there is a marked increase in antidepressant use among individuals with no psychiatric diagnosis, revealed by researchers. Americans are no strangers to antidepressants.
Successfully tested in Rwanda, mChip diagnoses infectious diseases like HIV and syphilis at patients’ bedsides; new device could streamline blood testing worldwide – New low-cost diagnostics like the mChip can revolutionize medical care around the world, revealed by researcher in US. Microfluidics-the manipulation of small amounts of fluids-and nanoparticles can be successfully leveraged to produce a functional low-cost diagnostic device in extreme resource-limited settings.
International survey highlights great public desire to seek early diagnosis of Alzheimer’s — Results from Europe and US highlight interest in early diagnosis despite wide fear of and familiarity with the condition – Results of an international survey reveal that over 85% of respondents in the five countries surveyed say that if they were exhibiting confusion and memory loss, they would want to see a doctor to determine if the cause of the symptoms was Alzheimer’s disease. Over 94% would want the same if a family member were exhibiting the symptoms.
Cancer mortality rates are higher in men than women – Overall cancer mortality rates are higher for men than women in the United States. Men are more likely to die from cancer than women. For many cancers, men have poorer survival than women but the differences are slight, and this is due to the greater frequency of cancer diagnosis, rather than poorer survival once the cancer occurs.
Study of twins suggests genetic component of autism spectrum disorders may be moderate — Environmental component may be substantial – Shared environmental factors ? experiences and exposures common to both twin individuals ? accounted for 55% of strict autism and 58% of more broadly defined autism spectrum disorders (ASD), revealed by researchers. Genetic heritability accounted for 37% of autism and 38% of ASD.
Nearly half of women with advanced breast cancer in the US not receiving life-saving treatment – UT MD Anderson research finds use of post-mastectomy radiation therapy static despite evidence-based guidelines of its benefits – Forty-five percent of women with advanced breast cancer in the U.S. did not receive postmastectomy radiation therapy (PMRT) despite the publication of evidence-based guidelines outlining PMRT as a potentially lifesaving treatment, according to new research from The University of Texas MD Anderson Cancer Center. The study, published in the July issue of Cancer, found that PMRT use rates for women with advanced breast cancer have remained static since 1999.
Shanghai CDC and Hutchinson Center establish Shanghai Breast Health Resource Center — First ‘learning laboratory’ of the Hutchinson Center-based Breast Health Global Initiative in China – The prevention, early detection and multidisciplinary treatment of breast cancer are important strategies for promoting health and extending a healthy life span. The Shanghai Breast Health Resource Center is an important step in effectively addressing breast cancer, especially to improving breast cancer screening and early detection, which are considered to be the most effective and affordable ways for a rapid reduction of breast cancer disease burden in developing countries like China.
Smoking may increase risk of prostate cancer recurrence, death – Researchers found that men with prostate cancer who were current smokers had a 61% increased risk of dying from prostate cancer, and a 61% higher risk of recurrence compared with men who never smoked. This new study from Harvard School of Public Health (HSPH) and University of California, San Francisco, researchers suggests that men with prostate cancer who smoke increase their risk of prostate cancer recurrence and of dying from the disease.
Brain imaging study of preschoolers with ADHD detects brain differences linked to symptoms — Smaller brain volumes associated with severity of ADHD symptoms – Brain development appear to play an important role among children presenting with early onset symptoms of ADHD (Attention-deficit/Hyperactivity Disorder). Researchers found reduced caudate volumes in affected children compared to the children who did not present with ADHD symptoms.
High risk of Parkinson’s disease for people exposed to pesticides near workplace — Study first to implicate pesticide ziram as possible cause for disease – In April 2009, researchers at UCLA announced they had discovered a link between Parkinson’s disease and two chemicals commonly sprayed on crops to fight pests. That epidemiological study didn’t examine farmers who constantly work with pesticides but people who simply lived near where farm fields were sprayed with the fungicide maneb and the herbicide paraquat.
