Right Fusiform Gyrus Infarct with Acute Prosopagnosia
Acta Neurol Taiwan. 2022 Dec 30;31(4):186-187.ABSTRACTA 56-year-old, right-handed man with no known past medical history presented with sudden onset of inability to recognize familiar individuals in person, including his wife and his mother. He also couldn't recognize himself in the mirror. There was no weakness, numbness, visual disturbances, or speech difficulty. Face recognition test, using Warrington Recognition Memory Test (1), showed the presence of complete prosopagnosia. The rest of the neurological and cranial nerves examinations were normal. Magnetic resonance imaging (MRI) of the brain showed restricted diffusio...

Air pollution linked to irregular heartbeat and lung blood clots
Conclusion This was a large national study that looked in detail at links between people's short-term exposure to air pollutants and national records on hospital admissions for heart attack, emergency admissions for all cardiovascular problems, and deaths from cardiovascular disease. The study had some limitations – for example, as the authors say, it did not include heart attacks that took place before hospital admission. It also used fixed monitoring sites, which may not accurately reflect personal exposure to air pollution.  For the public, the results of this study are probably confusing. That's because the resear...

The medical use of oxygen: a time for critical reappraisal
Abstract Oxygen treatment has been a cornerstone of acute medical care for numerous pathological states. Initially, this was supported by the assumed need to avoid hypoxaemia and tissue hypoxia. Most acute treatment algorithms, therefore, recommended the liberal use of a high fraction of inspired oxygen, often without first confirming the presence of a hypoxic insult. However, recent physiological research has underlined the vasoconstrictor effects of hyperoxia on normal vasculature and, consequently, the risk of significant blood flow reduction to the at‐risk tissue. Positive effects may be claimed simply by relief of a...

Ancrod revisited: viscoelastic analyses of the effects of Calloselasma rhodostoma venom on plasma coagulation and fibrinolysis
Abstract Fibrinogen depletion via catalysis by snake venom enzymes as a therapeutic strategy to prevent or treat thrombotic disorders was utilized for over four decades, with ancrod being the quintessential agent. However, ancrod eventually was found to not be of clinical utility in large scale stroke trial, resulting in the eventual discontinuation of the administration of the drug for any indication. It was hypothesized that ancrod, possessing thrombin-like activity, may have unappreciated robust coagulation kinetics. Using thrombelastographic methods, a comparison of equivalent tissue factor initiated thrombin ...

Pretreatment of Mouse Neural Stem Cells with Carbon Monoxide-Releasing Molecule-2 Interferes with NF-κB p65 Signaling and Suppresses Iron Overload-Induced Apoptosis.
Abstract Neural stem cell (NSC) transplantation is a promising approach to repair the damaged brain after hemorrhagic stroke; however, it is largely limited by the poor survival of donor cells. Breakdown products of the hematoma and subsequent iron overload contribute to the impairment of survival of neural cells. There is little information regarding the mechanism involved in the death of grafted cells. Furthermore, therapeutic research targeted to improving the survival of grafted neural stem cells (NSCs) is strikingly lacking. Here, we showed that iron overload induced apoptosis of C17.2 cells, a cell line orig...

IJERPH, Vol. 14, Pages 423: Ambient Air Pollution and Out-of-Hospital Cardiac Arrest in Beijing, China
Air pollutants are associated with cardiovascular death; however, there is limited evidence of the effects of different pollutants on out-of-hospital cardiac arrests (OHCAs) in Beijing, China. We aimed to investigate the associations of OHCAs with the air pollutants PM2.5 –10 (coarse particulate matter), PM2.5 (particles ≤2.5 μm in aerodynamic diameter), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3) between 2013 and 2015 using a time-stratified case-crossover study design. We obtained health data from the nationwide emergency medical service database; 4720 OHCA cases of cardiac ori...

Hookah smoking raises cardiovascular risk comparable to traditional cigarette smoking, study finds
This study is believed to be the first to investigate the effects of hookah smoking on stiffening of the arteries. Studies have shown that as cigarette use continues to decline, hookah smoking is rising, especially among youth and particularly among college students.“We know that flavored tobacco products are frequently the first kind of tobacco product used by youth,” Rezk-Hanna said. “One of the major issues with hookah is the fact that the tobacco is flavored with fruit, candy and alcohol flavors, making hookah the most popular flavored tobacco produc t among this audience.”According to the Food and Drug Admini...

Is Aberrant Reno-Renal Reflex Control of Blood Pressure a Contributor to Chronic Intermittent Hypoxia-Induced Hypertension?
This study demonstrated unaltered vascular conductance in response to lumbar sympathetic stimulation in CIH-exposed rats. Aortic compliance was increased and estimated blood volume was unchanged in CIH-exposed rats. Increased blood pressure was related to an increase in cardiac output, which was confirmed by echocardiography (Lucking et al., 2014). It is suggested therefore that hypertension in the CIH model can be evoked by over-excitation of the cardiac arm of sympathetic nervous system (SNS), even before mechanisms of enhanced peripheral vasoconstriction and endothelial dysfunction are initiated (Naghshin et al., 2009)....
