Nobel Medicine Prize won by doctors for work on cells' response to oxygen

Two Americans and a Briton won the 2019 Nobel Medicine Prize on Monday for discovering a molecular switch that regulates how cells adapt to fluctuating oxygen levels, opening up new approaches to treating heart failure, anaemia and cancer.

Abstract BACKGROUND: Heart failure (HF) and cancer (CA) are becoming increasingly prevalent as the population ages. We aimed to evaluate prior history and occurrence of CA and its prognostic impact on HF.Methods and Results:Consecutive hospitalized HF patients (n=2,103) were divided into 2 groups according to prior history of CA: non-prior-CA group (n=1,828) and prior-CA group (n=275). Compared with the non-prior-CA group, the prior-CA group were older, and had higher prevalence of chronic kidney disease, anemia, and atrial fibrillation (P

AbstractHeart failure (HF) is a potentially debilitating condition, with a prognosis comparable to many forms of cancer. It is often complicated by anemia and iron deficiency (ID), which have been shown to even further harm patients ’ functional status and hospitalization risk. Iron is a cellular micronutrient that is essential for oxygen uptake and transportation, as well as mitochondrial energy production. Iron is crucially involved in electrochemical stability, maintenance of structure, and contractility of cardiomyocytes. There is mounting evidence that ID indeed hampers the homeostasis of these properties. Anima...

Abstract The case of a 61-year-old male with a recent total gastrectomy for a hemorrhagic gastric tumor is presented, with the important co-morbidities of type II diabetes mellitus requiring insulin, chronic hepatitis C with liver dysfunction, stage II essential hypertension, chronic stage III renal disease peripheral type II aorto-iliac disease with stage II ischemia of both legs, and chronic anemia. About one month following the gastrectomy, the patient presented with fever and acute inflammatory syndrome. Severe aortic insufficiency, aortic valvular vegetations, and positive blood cultures with Staphylococcus s...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...

AbstractGuidelines recommend angiotensin-converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) for treatment of heart failure with reduced ejection fraction (HFrEF), but these medications are underprescribed in clinical practice. We reviewed the records of HF patients receiving a first visit in a tertiary outpatient clinic from January 1st 2004 to May 31st 2015, and selected those with a serum creatinine concentration (sCr) available at both the first and last visit and

AbstractBackgroundHeart failure (HF) and non-cardiac comorbidities often coexist and are known to have an adverse effect on outcome. However, the prevalence and prognostic impact of non-cardiac comorbidities in patients with HF with reduced ejection fraction (HFrEF) vs. those with preserved (HFpEF) remain inadequately studied.Methods and resultsWe used data from the Swedish Heart Failure Registry from 2000 to 2012. HFrEF was defined as EF

CONCLUSION: LV-functional non-recovery was not uncommon in breast cancer patients with trastuzumab-induced cardiomyopathy, and non-recovered LVD was significantly associated with MACEs. Decreased LVEF, enlarged LV size, pulmonary hypertension, and anemia were independent predictors of LV-functional non-recovery. Careful monitoring for MACEs and intensive medical management should be considered in trastuzumab-induced cardiomyopathy with these characteristics. PMID: 30737527 [PubMed - as supplied by publisher]
