Lung ventilation-perfusion scintigraphy – Cardiology MCQ – Answer
Lung ventilation-perfusion scintigraphy has a negative predictive value of nearly — percent for excluding thromboembolic pulmonary hypertension: Correct answer: a) 100% Because of the nearly 100% negative predictive value,  a normal lung ventilation-perfusion scintigraphy (V/Q scan) virtually excludes the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH). V/Q scanning has a high sensitivity of 96 – 97.4% for detecting perfusion abnormalities. But V/Q scan being not very specific, its diagnostic utility is low. It can only be used as an initial screening test. Any abnormal test requires additio...

Fight Aging! Newsletter, May 28th 2018
This study indicates that frailty and other age-related diseases could be prevented and significantly reduced in older adults. Getting our heart risk factors under control could lead to much healthier old ages. Unfortunately, the current obesity epidemic is moving the older population in the wrong direction, however our study underlines how even small reductions in risk are worthwhile." The study analysed data from more than 421,000 people aged 60-69 in both GP medical records and in the UK Biobank research study. Participants were followed up over ten years. The researchers analysed six factors that could impact on...

Are Mitochondria at the Root of Age-Related Loss of Muscle Mass and Strength?
Sarcopenia, the age-related loss of muscle mass and strength, has many possible contributing causes. There is fair evidence for most of them, from a failure to process amino acids needed for construction of new muscle mass to damaged neuromuscular junctions to loss of stem cell function. The most compelling evidence I've seem points to that stem cell dysfunction as the most significant contribution. It is certainly the case that stem cell populations decline in size and activity with age, reducing the supply of daughter cells needed to maintain tissues in good condition. Muscle stem cells are among the most studied in agin...

MKSAP: 62-year-old man is evaluated during a routine visit
Test your medicine knowledge with the MKSAP challenge, in partnership with the American College of Physicians. A 62-year-old man is evaluated during a routine visit. He is asymptomatic and walks 1 mile most days of the week. Medical history is significant for aortic stenosis, type 2 diabetes mellitus, hypertension, and hyperlipidemia. Medications are aspirin, metformin, lisinopril, metoprolol, and rosuvastatin. On physical examination, the patient is afebrile, blood pressure is 130/66 mm Hg, pulse rate is 68/min, and respiration rate is 14/min. BMI is 29. Cardiac examination reveals a grade 2/6 early-peaking systolic mur...

New Organ Preservation Device Keeps Livers Alive Longer and Better for Transplanation
The success of a liver transplant is significantly limited by the quality of the donor organ. Currently this results in a severe shortage of acceptable organs, as many potential organs do not tolerate the static cold storage (SCS) of the conventional transplant procedure. Despite significant clinical advances in transplant procedures over the past 30 years, the mechanism for liver preservation has changed very little: the organ is flushed and placed on ice, lowering metabolic activity ten-fold in the hope of reducing damage. However, over time ischemic damage occurs, which reduces organ viability, and the cooling process r...

How To Get Pregnant Faster? The Ava Fertility Tracker Review
The Ava fertility tracker offers a viable alternative to menstruation and fertility tracking apps as it promises accurate data measurement and a user-friendly solution for women trying to get pregnant. We tested the tracker and had an overall positive experience. Here’s our verdict. Biology tends to play tricks on women Before the digital age, the workings of the female body were even more mysterious and challenging to follow than today. Although women always had to be aware of the milestone dates of their cycles every month, tracking it was a hassle. Ten or fifteen years ago, paper-based menstruation calendars were sup...

Besides the Nonspecific T-wave Inversion in aVL, What Else is Abnormal on this ECG?
This case was sent by Laszlo Farkas, a paramedic from Hungary.  He discussed it with Janos Borbas MD and Robert Sepp MD from University of Szeged 2nd Department of Internal Medicine and Cardiology Clinic. The case inspired me to resurrect a case that I published 10 years ago with the same ECG finding (2nd case below).What is the finding?What does it signify?CaseAn elderly male presented with chest pain.  Here is the first ED ECG:Hint: the finding is NOT the T-wave inversion in aVLThis ECG that I published 10 years ago in Critical Decisions in Emergency and Acute Care Electrocardiography has th...

ETCO2 monitoring in ICU – capnography
ETCO2 monitoring in ICU – capnography ETCO2 monitoring in ICU – capnography ETCO2 monitoring in ICU – capnography: End tidal carbon dioxide (ETCO2) is the partial pressure of carbon dioxide (CO2) in exhaled air at the end of expiration. Normal values are in the range of 35 –  45 mm Hg. Carbon dioxide monitoring is also known as capnography. The graphical representation of CO2 is known as capnogram. In the monitor screenshot shown above, shown the capnogram at the bottom. Here the ETCO2 is shown as 28 mm Hg. It is below the lower limit and could be due to hyperventilation in a spontaneously breathin...

Fight Aging! Newsletter, March 26th 2018
In conclusion, senescence of vascular cells promotes the development of age-related disorders, including heart failure, diabetes, and atherosclerotic diseases, while suppression of vascular cell senescence ameliorates phenotypic features of aging in various models. Recent findings have indicated that specific depletion of senescent cells reverses age-related changes. Although the biological networks contributing to maintenance of homeostasis are extremely complex, it seems reasonable to explore senolytic agents that can act on specific cellular components or tissues. Several clinical trials of senolytic agents are currentl...

Why measuring uterine blood flow is pointless in an IVF cycle
Lots of IVF specialists monitor uterine blood flow during an IVF cycle. They believe that this helps them to track uterine receptivity, and good flow correlates with implantation rates. This makes logical sense, which is why so many sonographers study uterine blood flow doppler wave forms and the PI ( pulsatility index)I think this is meaningless.The fact that the endometrium is growing to a thickness of 8 mm means that it is receiving adequate perfusion - how would it be able to grow without an adequate blood supply ?This is another one of those measurements which are of no clinical value - but are done simply because we ...
