Individuals with Parkinson's disease who had normal cognition at baseline had similar odds of mortality as those in the general population, but shorter survival was found among those with mild cognitive impairment, dementia onset, postural imbalance and gait disorder, freezing of gait, elevated disease severity, hyposmia and slower performance in the Timed Up and Go test, researchers reported in Neurology. The findings also showed that increased cerebrospinal fluid leukocytes and lower dopamine transporter activity had a significant link to shorter Parkinson's survival.
Advancements in Theranostics Theranostics allow clinicians to determine appropriate treatments based on imaging and then deliver the treatments focused on the same imaged targets. MIM's advanced segmentation, image registration, and dosimetry tools are well-equipped to manage the latest advances in this field. Learn more
Chinese researchers found that mice with Parkinson's disease that received astilbin, a flavanonol found in several plants and alcoholic beverages, had significantly better motor function, as well as reduced dopaminergic neuron loss, glia cell activation in the substantia nigra and oxidative stress, suggesting its neuroprotective effects, compared with controls that were given a saline solution. The findings were published in the journal International Immunopharmacology.
A data review conducted by US cancer centers, including the National Cancer Institute, found that Hispanic adults with HIV living in the US are at an increased risk of human papillomavirus-related cancers, with the highest risk being for anal cancer, according to findings in the journal Cancer. Researchers culled data from the HIV/AIDS Cancer Match Study and took into account survival and incidence rates among Hispanics, non-Hispanic blacks and non-Hispanic whites.
Patients with human papillomavirus-positive throat cancer who received standard cisplatin chemotherapy had a substantially higher two-year overall survival rate, as well as fewer recurrences and deaths over six years, compared with those who were given cetuximab, according to a study in The Lancet. Researchers found similar toxicity and side effects with the treatments.
The FDA gave Spectrum Dynamics 510(k) clearance for its VERITON-CT 64 SPECT/CT system, a digital wide-bore scanner that features 360-degree multidetector geometry and provides threefold higher volumetric sensitivity and twofold increased throughput, compared with conventional dual-head analog SPECT cameras.
Hermes Medical Solutions launched its Hybrid3D selective internal radiation therapy software, which offers FDA-approved technetium-99m macroaggregated albumin dose planning using glass and resin microspheres and yttrium-90 microsphere dose verification.
A study of US and Canadian programs published in the American Journal of Roentgenology showed that only eight of 59 faculty members in nuclear medicine with leadership roles were female, and only about 13% and 12.5% held first- and second-in-command roles, respectively, compared with 87% and 87.5% of men. "This discrepancy calls for new strategies to promote diversity in leadership and academia in nuclear medicine," researchers concluded.
Republicans want to push through some key health care bills during the lame-duck session of Congress, covering issues such as drugmaker contributions to the Medicare Part D "doughnut hole," the CREATES Act and the medical device tax. The measures could be included in the must-pass government funding bill but there is not much interest among Democrats in cooperating, and lobbyists say they are not optimistic about anything getting done.
Data-driven diagnostic and intervention techniques promise to improve health care, and though they will for many people, they also threaten to widen inequalities, writes Zeynep Tufekci. Tufekci writes that he is not arguing against health care technology but is advocating for equitable outcomes and measures to prevent new forms of discrimination.
