Studies: Surging Number Of Deaths From Heart Failure Tied To Aging Population, Obesity Rates

From a Wall Street Journal online article:

The rapid aging of the population, together with high rates of obesity and diabetes in all ages, are pushing both the rate and number of deaths from heart failure higher, the study said. Most deaths from heart failure occur in older Americans, but they are rising in adults under 65, too, the study showed.

Heart Failure Increase in Aging PopulationThe findings help explain why a decadeslong decline in the death rate from cardiovascular disease has slowed substantially since 2011 and started rising in middle-aged people, helping drive down U.S. life expectancy.

Deaths from heart failure, one of the nation’s biggest killers, are surging as the population ages and the health of younger generations worsens.

The death rate from the chronic, debilitating condition rose 20.7% between 2011 and 2017 and is likely to keep climbing sharply, according to a study published Wednesday in the journal JAMA Cardiology.

Travel Destinations: Bonefishing In Bermuda Combines Luxury Leisure With Island Adventure

From a Wall Street Journal online review:

Bonefishing in Bermuda Wall Street JouranlWe headed west and hugged the shallow shoreline, casting at shadows of fish as the sun mixed with clouds making it more difficult to sight fish. We curled around a point of land I instantly recognized as Cambridge Beaches, where I stayed with my parents on my first visit to the island and where my sister celebrated her honeymoon.

Mr. Linnell used a push pole to move the skiff quietly along shore as he chatted up guests snorkeling nearby, expertly keeping them away from our bonefish spots by urging the snorkelers to take in sights a safe distance away.

I HAD NEVER considered fly fishing for bonefish in Bermuda. Chasing the elusive, silver-green creatures, prized for their fight, was something you did at remote outposts and rustic camps, where showering was optional and accommodations primitive. Such a trip could be fun for a few days, but you’d never dare drag your wife or kids along.

Dementia Studies: Healthy Sleep, Diet And Exercise Changes Boost Cognition

From a Wall Street Journal online article:

Alzheimer's & Dementia JournalMr. Chambers, a 48-year-old physical therapist in Jersey City, N.J., modified his sleep, diet and exercise routines. Eighteen months later, his performance on a battery of cognitive tests improved, particularly in areas like processing speed and executive function, such as decision-making and planning.

Most surprising, says Dr. Isaacson, is that the MCI patients who followed at least 60% of their recommendations showed cognitive improvement. However, MCI patients who followed less than 60% of the recommendations experienced cognitive declines similar to the control groups, he notes.

Mr. Chambers is among 154 patients in a study, published Wednesday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, that doctors say shows encouraging results. Among healthy patients, people who made changes in nutrition and exercise showed cognitive improvements on average. People who were already experiencing some memory problems also showed cognitive improvement—if they followed at least 60% of the recommended changes.

Science Podcasts: Quest To Detect Gravitational Waves, First Hypothesised By Einstein (Nature)

Nature PodcastIn 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time known as gravitational waves. These waves were produced by the final spiral of two oribiting black holes that smashed into each other, sending ripples across the universe.

In this Podcast Extra, Benjamin Thompson speaks to Cole Miller from the University of Maryland about the quest to detect gravitational waves, which were first hypothesised by Albert Einstein back in 1916.

Transportation: Cambridge University Builds Ultra-Efficient, 560-Mile Range Electric Car

From a Dezeen.com online review:

On a single charge, Helia can cover a range of 900 kilometres – the distance from London to Edinburgh. Again, compared to the Tesla 3, the Cambridge University team’s car has double the range on a battery a quarter of the size.

Helia Cambridge Electric CarThe ability to cover this distance is aided by Helia’s chassis and body panels made from carbon fibre, which grant it a kerb weight of 550 kilograms.

Students from Cambridge University have built an ultra-efficient electric car that drives using only as much power as it takes to boil a kettle.

The Cambridge University Eco Racing (CUER) student society built the four-seater car, named Helia, with efficiency as the main goal.

Their achievement has been to produce a car that can travel 80 kilometres-per-hour using only 2500 watts, or as much power as it takes to boil a single kettle, which is equivalent to 31 watt-hours-per-kilometre.

Ethics Of Lying About A Terminal Cancer Diagnosis Explored In Movie “The Farewell”

From a New Scientist online review:

The prevailing narrative of “battling cancer” in Western society has its own issues, with its discourse of personal triumph that values individual responsibility and determination. But the alternative – to lie outright – might seem inconceivable, particularly to those accustomed to the norms of Western culture. It is, however, a common practice in China, rooted in the belief that telling a person about their diagnosis can make their condition deteriorate quicker.

 

The Farewell Movie about Cancer DiagnosisThe plot line of The Farewell is familiar to me. Like Billi’s Nai Nai, my aunt was diagnosed with metatastic lung cancer. Nobody in the family told her – nor did the doctors when she later underwent surgery to remove a tumour. The last time I saw her was in north-eastern China a few years ago. Her once-plump figure had shrunk to a wiry frame. She was in her early 70s, in good spirits, but a far cry from the feisty matriarch who used to dominate conversations.

The Farewell is a heartfelt film, punctuated by moments of unexpected – and unexpectedly uplifting – humour. In a darkly comical scene in a printing shop, Nai Nai’s younger sister demands that the results of a medical report be doctored to edit out references to cancerous nodules and replaced with the nebulous term “benign shadows”.
