J & J ’ s Cerenovus wins FDA nod for Embotrap II revascularization device
Johnson & Johnson‘s (NYSE:JNJ) Cerenovus said today it won FDA 510(k) clearance for the Embotrap II revascularization device.
The Irvine, Calif.-based J&J division said that the device is designed to quickly restore natural blood flow by retrieving emboli within the vasculature of the brain, using minimal compression to protect against further complications.
Approval of the device came based on data from the Arise II study, in which investigators reported being able to restore blood flow in 80% of patients treated within three passes, and in approximately 50% within a single pass. More than 66% of patients ...

New Insights from Studies of Clonal Hematopoiesis.
Abstract
Clonal hematopoiesis (CH) describes an asymptomatic expansion of blood cells descended from a single hematopoietic stem cell. Recent studies have shown that CH increases in frequency with aging, and is often driven by somatic mutations in genes that are recurrently mutated in hematologic malignancies. When CH is associated with a mutation in a leukemia-associated gene at a variant allele frequency of 0.02 or greater, it is termed "clonal hematopoiesis of indeterminate potential" (CHIP). CHIP has a 0.5-1% risk per year of progression to hematological neoplasia, and increases both all-cause mortality and ...

Neurocognitive deficits in older patients with cancer
Conclusion Neurocognitive deficits (MCI and dementia) are more common in older adults with cancer. Factors associated with neurocognitive deficits include high comorbidity, stroke, warfarin use and metastatic cancer. Identification and management of these conditions is of great relevance in the course of cancer therapy.

Severe Symptoms, but a Truly Treatable Disease
BY NOURA MAHDI; DARRON LEWIS; JEREMY OSBORNE; & AHMED RAZIUDDIN, MDA 73-year-old man was brought to the emergency department from his nursing home for rectal bleeding and anemia. The patient mentioned he had had episodes of bright red rectal bleeding and constipation for a few months. A colonoscopy had been done prior to the visit, which revealed a large intestine tumor and biopsy confirming adenocarcinoma. He was awaiting an appointment with his surgeon.The patient reported bloody rectal leakage, and a CBC done at the nursing home showed a hemoglobin level of 7.2. He also complained of dyspnea but denied any other ...

New-Onset Cardiovascular Morbidity in Older Adults With Stage I to III Colorectal Cancer.
Conclusion Older patients with colorectal cancer are at increased risk of developing CVD and CHF. Diabetes and hypertension interact with chemotherapy to increase the risk of cardiovascular morbidity. Future studies should assess the potential for personalized therapeutic options for those with preexisting morbidities and for structured monitoring for patients with a history of exposure to chemotherapy regimens, as well as explore the management of preexisting comorbidities to address long-term cardiovascular morbidity.

Change in pulmonary function and cardiorespiratory fitness following chemotherapy in testicular cancer patients - a pilot study
Conclusions: There was a substantial reduction in VO2max after BEP corresponding to three decades of physiological aging. This reduction may reflect a decrease in the patients’ cardiac function and oxygen carrying capacity, and not to reduced DLco.

Nivolumab-induced posterior reversible encephalopathy syndrome
A 47-year-old woman with metastatic, poorly differentiated lung cancer with neuroendocrine features was brought to the hospital after 4 days of nausea, vomiting, disorientation, and 1 generalized tonic clonic seizure. On examination, her blood pressure was 148/95 mm Hg, heart rate 95 bpm, and temperature 36.4°C. She was encephalopathic and had cortical blindness. She had no history of seizures or visual impairment. MRI brain without contrast showed changes consistent with posterior reversible encephalopathy syndrome (PRES; figure, A). She had been on nivolumab, of which she had received 2 doses; the last dose was 24 da...

Juvenile melanomas: Western Australian Melanoma Advisory Service experience.
CONCLUSIONS: Juvenile melanoma remains a rarity in Western Australia despite a very high incidence of adult melanoma. Unlike in adults, no definitive risk factors have been established. A significant proportion of this cohort had a pre-existing naevus and while most melanomas occurred in sun-exposed areas in light-skinned individuals the association between sunburn and melanoma was not strong.

Association of cancer and Alzheimer's disease risk in a national cohort of veterans.
DISCUSSION: Survivors of some cancers have a lower risk of AD but not other age-related conditions, arguing that lower AD diagnosis is not simply due to bias. Cancer treatment may be associated with decreased risk of AD.

Chemotherapy induced stroke mimic: 5-Fluorouracil encephalopathy fulfilling criteria for tissue plasminogen activator therapy
Stroke mimics, especially those involving chemotherapy related neurotoxicity, can confound the clinical diagnosis of acute stroke. Here we describe the case of a 63year-old male with a recent history of stage IIIC colon cancer who presented with confusion on the second day of modified FOLFOX6 (5-fluorouracil/oxaliplatin) chemotherapy and subsequently received alteplase, tissue plasminogen activator therapy (tPA), for presumed ischemic stroke. Magnetic resonance imaging scans after tPA administration did not reveal evidence of an infarction and the patients' neurological symptoms resolved completely after discontinuation of...

The Global End-Diastolic Volume (GEDV) Could Be More Appropiate to Fluid Management Than Central Venous Pressure (CVP) During Closed Hyperthermic Intrabdominal Chemotherapy with CO2 Circulation.
CONCLUSIONS: Closed intrabdominal chemotherapy with CO2 circulation model may be a safe model for HIPEC by means of a gas exchanger. GEDV and its changes significantly correlated to CI, and not observed for CVP. GEDV values may be more appropriate for monitoring cardiac preload, blood loss limitation and to predict changes in intravascular volume status during intraperitoneal chemotherapy.

Cancer, atrial fibrillation, and stroke
Cancer patients appear to be at increased risk for atrial fibrillation. Although surgery and chemotherapy exacerbate this risk, this association is observed even in the absence of any cancer-specific treatment. The underlying mechanism of this is likely multifactorial, but systemic inflammation and autonomic dysregulation are hypothesized to play critical roles. Cancer and atrial fibrillation are both independent risk factors for ischemic stroke; however, it is not clear whether this translates to an increased risk of stroke in patients with both comorbidities.

Capecitabine-induced acute toxic leukoencephalopathy.
Abstract
A 45-year-old woman was treated by Capecitabine (Xeloda(®)) during 6days for breast cancer with metastatic bone lesions when she presented with nausea, headaches, muscle cramps, dysarthria and swallowing disorders. A stroke was first suspected. Brain CT was normal. MRI showed bilateral and symmetric high signal intensities of deep white matter, corpus callosum and corticospinal tracts on diffusion-weighted imaging and T2 fluid-attenuated inversion recovery (FLAIR) sequence, similar to 5-FU acute leukoencephalopathy. An acute toxic leukoencephalopathy was diagnosed prompting to discontinue capecitabine, w...
