When travelling the globe, most intrepid adventurers and holiday-makers will encounter only minor health problems. But knowing and understanding possible hazards is fundamental to preventing them. When planning an adventure, people often seek novel experiences – and contemporary travel is able to take us (within just a few hours) from a relatively benign environment to a potentially life-threatening setting.
Several widely circulated opinion pieces assert that because there is no detectable increase in all brain cancers in Australia in the past three decades, cell phones do not have any impact on the disease. There are three basic reasons why this conclusion is wrong.
Dementia, from the Latin demens, is a persistent disorder of the mental processes marked by memory disorders, personality changes, and impaired reasoning. It affects 47.5 million people worldwide, and there are 7.7 million new cases annually. This year’s Dementia Awareness Week (15-21 May 2016) aims to bring recognition and awareness to this neurological illness.
All over the world, populations are changing. People are living longer, and older people are forming a larger percentage of the global population. Baby boomers are retiring and improved health care has extended life expectancy. At the same time, as globalisation and urbanisation break apart familiar social and family structures, more older adults are living alone or without social support.
Philosophers of science are in the business of explaining the special features of science, like the unifying power of scientific explanation and the wonderful sense of understanding it produces. We try to explain the amazing success of modern scientific theories, the structure of inductive inference in the science, and extract systematic positions – like realism, constructivism, and empiricism – from the evidence of theoretical success.
In an op-ed published in the New York Times titled “Why You Hate Work”, Schwartz and Porath highlighted Gallup data that revealed that only 30% of employees in the US and 13% across 142 countries feel engaged at work. Noting the high rate of burnout, they declared that for most of us, work is a depleting, dispiriting experience that is getting worse.
Global population is aging rapidly. Over the next four decades the number of individuals aged 60 years and older will nearly triple to more than 2 billion in 2050 (UN, 2013). Mindful physical exercise has become an increasingly utilized approach for improving psychological well-being and is defined as “physical exercise executed with a profound inwardly directed contemplative focus.”
Addiction is not a condition that springs to mind when we think of afflictions of the elderly, and yet it probably should be. Until now, alcohol or substance abuse among older patients has received relatively little attention, either as a clinical focus or as a research initiative. But we can no longer afford to neglect this growing cohort of affected individuals.
With bursts of sunshine starting to break through the relentless spring showers, the world is gearing up for summer. For a lot of us, that means getting away for a few weeks, and enjoying the glorious sunshine that the warmer weather brings. Unfortunately, basking in the summer sunshine isn’t without its risks.
“We are getting more and more precise about the different risk factors for the various subtypes of cancer,” said Stephen Hursting, PhD, MPH, professor in the department of nutrition at the University of North Carolina at Chapel Hill. One established factor is obesity, now well linked to at least ten cancers, including pancreatic, colorectal, endometrial, and hormone receptor–positive, postmenopausal breast cancer.
In these days of Zika, Chikungunya, Dengue, and Ebola pandemics, and with the devastating smallpox, influenza, and polio epidemics of the 20th century still fresh in our collective memories, it seems counterintuitive to consider the possibility that viruses will ever be regarded other than with fear and loathing. However, if trials currently underway in Europe, Australia, and the US prove successful, then we may eventually reach a point where certain viruses are viewed with approval and even a degree of affection.
You may have heard of people suffering from a broken heart, but Takotsubo syndrome (TTS) or “Broken heart syndrome” is a very real condition. However, new research shows that happiness can break your heart too. TTS is characterised by a sudden temporary weakening of the heart muscles that cause the left ventricle of the heart to balloon out at the bottom while the neck remains narrow
In recent years, biological sciences have witnessed a surge in the generation of data. This trend is set to continue, heralding an increased need for bioinformatics research. By 2018, sequencing of patient genomes will likely produce one quintillion bytes of data annually – that is a million times a million times a million bytes of data. Much of this data will derive from studies of patients with cancer.
The 2016 World Malaria Report estimates that there were approximately 215 million cases of malaria and 438,000 deaths in 2015. The majority of deaths occur in sub-Saharan Africa and among young children, and malaria remains endemic in around 100 countries with over three billion people at risk. Over the past 15 years there have been major gains in reducing the global burden of malaria
Over the past few years, the momentum of research and efforts on malaria has tremendously decreased malaria transmission and the number of deaths from this disease. However, in many poor tropical and subtropical countries of the world, malaria continues to be one of the leading causes of illness and death.
The man doing a spot of gardening cleaning out his fishpond in Europe, the woman who becomes unwell after giving birth in rural India, the child with pneumonia in Rwanda, and the senior citizen who develops diverticulitis in Singapore – the triggers are different but they all die from the same disease process: sepsis.
