Researchers discovered a steady decline in the West Antarctic ice sheet over the past few thousand years, raising concerns about its future behavior. The ice sheet contains enough water to raise global sea level by 5 meters, threatening coastal regions with disastrous consequences.
Researchers have found a promising combination therapy that may significantly improve treatment outcomes for patients with advanced prostate cancer. In a phase II clinical trial, the combination of calcitriol and docetaxel showed a higher PSA response rate compared to docetaxel alone.
A study of 7,300 people found that intermittent lack of insurance coverage resulted in lower use of clinical preventive services. This decrease was particularly pronounced for women who underwent fewer pap tests and mammograms, as well as men who received less prostate cancer screening.
A recent study published in the Milbank Quarterly found that patients are more likely to complain about administrative issues related to their health plans, rather than problems with medical care. The study revealed that patients who complained were five times more likely to have their concerns successfully resolved.
Experimental evidence suggests that stem cell implantation can trigger angiogenesis in damaged heart tissue, leading to improved blood flow and potentially safe treatment outcomes. However, further controlled studies are needed to fully understand the role of cell transplantation in myocardial regeneration.
A recent study found that doctors rarely counsel smokers on quitting and advise only 23% of binge drinkers about their alcohol use. This can result in millions of smokers and binge drinkers not receiving health interventions.
The study found that nearly half of promotional claims were not supported by corresponding references, with the most common error being recommending treatment to a different patient group than those assessed in the reference study. Doctors should be cautious when assessing advertisements claiming greater efficacy, safety, or convenience.
A 12-week study shows candesartan cilexetil significantly reduces headache days and sick leave in patients with migraines. The medication's benefits are associated with good tolerability, making it an exciting alternative to current therapies.
Hopkins researchers identify connexin 43 gene as the cause of oculodentodigital dysplasia, a disorder affecting multiple body systems. The study reveals changes in the gene's sequence are responsible for the condition.
A study of 216 cases found that 74% resulted from mishandling and 32% from potential deficiencies in firearm design. Researchers propose promoting safe storage and handling, as well as requiring safety features in new handguns to prevent unintentional shootings.
The National Institute of Arthritis and Musculoskeletal and Skin Diseases has awarded five new grants to researchers studying stem cells and their potential in treating various musculoskeletal diseases. These studies aim to investigate growth factors, muscle regeneration, connective tissue repair, bone disease treatment, and the develo...
Research explores whether animal antibiotics contribute to rising human resistance rates. The study finds that animal antibiotics can indeed fuel human antibiotic resistance, highlighting the need for stricter regulations on their use.
Researchers found that man-made wetlands in California's San Joaquin Valley can remove up to 69.2% of selenium from agricultural drainage water, converting it into non-toxic dimethyl selenide. The unique ecosystem of the wetlands acts as a bio-geo-chemical filter, trapping selenium in sediment and utilizing plant roots to metabolize it.
A study found that 42% of emergency patients waited more than 60 minutes for care, with longer waits in poorer neighborhoods. Emergency departments with better staffing ratios had shorter waiting times, suggesting physician and nurse staffing as a solution to reduce wait times.
Researchers discover evidence of culturally transmitted behaviors in orangutans, dating back 14 million years. The findings push back the origins of cultural transmission in apes, suggesting a stronger link to human culture.
Researchers at JILA have developed a new waveguide structure that coaxes light waves into traveling along at the same speed, producing well-synchronized photons firing out of the system. The breakthrough enables electromagnetic radiation with peak powers approaching a megawatt and produces nanometer-scale light waves.
Studies have found a direct correlation between global warming and biological changes in plants and animals globally. Over 1,200 species have undergone changes consistent with temperature change influencing various traits.
Research reveals cocaine causes harm to brain cells that trigger feelings of pleasure, potentially explaining addiction and depression. The study found significant lower levels of dopamine neurons in cocaine users compared to non-users.
In the Phase II study, natalizumab demonstrated higher rates of clinical remission compared to placebo at multiple time points. The highest rate of remission was observed in the dual 3 mg/kg dose group, with a maximal response of 71%.
Researchers confirm previous detection of chlorine in Io's plasma torus and model the breakdown of salt into sodium and chlorine atoms, providing insights into Io's volcanic activity and its potential meteoritic origins.
A Phase II study published in NEJM found that natalizumab significantly reduced new gadolinium-enhancing lesions by up to 93% and the number of patients experiencing relapses by 50%. The treatment was well-tolerated, with common adverse events including infection and rash.
A Stanford study finds that medications for heart disease, including warfarin, beta blockers, and ACE inhibitors, are underused in outpatient settings. The researchers urge improved education, quality-improvement practices, and patient involvement to address this issue and reduce complications.
A new testing method for Huntington's disease (HSS) has been discovered by researchers at Oregon Health & Science University and UCSF. The test uses magnetic resonance imaging (MRI) to identify the 'eye of the tiger sign' in patients with PANK2 mutations, a gene linked to HSS and Parkinson's disease.
A study analyzing 143 scientific papers and personal backyard recordings reveals that animals and plants are shifting their behaviors and seasonal timing due to a 0.6°C global temperature increase. In the temperate zone, species are shifting about five days earlier every ten years in response to warming temperatures.
