Bilateral anterior cerebral artery infarction presenting with acute paraparesis and parkinsonism

In patients with acute-onset paraparesis inferior, the concurrent presence of new onset cortical signs (abulia or mutism), and more rarely extrapyramidal signs, should alert clinicians to consider acute anterior bihemispheric ischemia. Prompt recognition of this rare form of acute cerebral stroke can enable timely delivering of acute thrombolytic or endovascular treatment.

Abstract Purinergic signaling was proposed in 1972, after it was demonstrated that adenosine 5'-triphosphate (ATP) was a transmitter in nonadrenergic, noncholinergic inhibitory nerves supplying the guinea-pig taenia coli. Later, ATP was identified as an excitatory cotransmitter in sympathetic and parasympathetic nerves, and it is now apparent that ATP acts as a cotransmitter in most, if not all, nerves in both the peripheral nervous system and central nervous system (CNS). ATP acts as a short-term signaling molecule in neurotransmission, neuromodulation, and neurosecretion. It also has potent, long-term (trophic) ...

In conclusion, older adults exhibited decreased markers of UPR activation and reduced coordination with autophagy and SC-associated gene transcripts following a single bout of unaccustomed resistance exercise. In contrast, young adults demonstrated strong coordination between UPR genes and key regulatory gene transcripts associated with autophagy and SC differentiation in skeletal muscle post-exercise. Taken together, the present findings suggest a potential age-related impairment in the post-exercise transcriptional response that supports activation of the UPR and coordination with other exercise responsive pathways (i.e....

This study sought to investigate what could be learned from how these men have fared. The men were born in 1925-1928 and similar health-related data from questionnaires, physical examination, and blood samples are available for all surveys. Survival curves over various variable strata were applied to evaluate the impact of individual risk factors and combinations of risk factors on all-cause deaths. At the end of 2018, 118 (16.0%) of the men had reached 90 years of age. Smoking in 1974 was the strongest single risk factor associated with survival, with observed percentages of men reaching 90 years being 26.3, 25.7, ...

In conclusion, the analyses do not permit us to predict the trajectory that maximum lifespans will follow in the future, and hence provide no support for their central claim that the maximum lifespan of humans is "fixed and subject to natural constraints". This is largely a product of the limited data available for analysis, owing to the challenges inherent in collecting and verifying the lifespans of extremely long-lived individuals. A reply from Jan Vijg's research group The authors of the accompanying comment disagree with our finding of a limit to human lifespan. Although we thank them for a...

CONCLUSION: Although rare, parkinsonism or other movement disorders may present as a stroke mimic with activation of a stroke code. Consulting neurologists should clarify the etiology for those patients with acute consciousness disturbance or motor weakness and avoid unnecessary thrombolysis. Key Words: Parkinson disease, parkinsonism, movement disorders, stroke code, thrombolysis. PMID: 28382611 [PubMed - in process]

Authors: Robson A, Sturman J, Williamson P, Conboy P, Penney S, Wood H Abstract This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK. This paper provides recommendations on the pre-treatment clinical assessment of patients presenting with head and neck cancer. Recommendations • Comorbidity data should be collected as it is important in the analysis of survival, quality of life and functional outcomes after treatment as well as for comparing results of different treatment regimens and different centres. (R) • Patients with hyp...

In this study, cangrelor was discontinued 1-6 hours prior to surgery, while aspirin was continued throughout the perioperative period. Bridging with cangrelor did not increase major bleeds prior to surgery, though minor bleeds, mostly ecchymosis at venipuncture site, was higher. P2Y12 assay documented sufficient platelet inhibition corresponding to levels required for anti thrombotic effect [1]. Cangrelor is awaiting approval and more large scale trials regarding the use of bridging are needed. Reference 1. Angiolillo DJ et al; BRIDGE Investigators. Bridging antiplatelet therapy with cangrelor in patients undergoing ...

The approval of first-of-a-kind drugs rose last year to forty-one, resulting in the highest level of newly approved U.S. drugs in nineteen years. The total number of new drugs approved last year was even higher at sixty-nine. The rising figures reflect an industry-wide desire to research and develop drugs for rare and hard-to-treat diseases. The newly approved drugs serve to advance medical care and the health of patients suffering from many ailments, including various forms of cancer, heart failure, and cystic fibrosis. Additionally, more than 40% of the new therapies were approved for treatment of rare or "orphan&...
