In 2014, more than 600 million adults were obese, equal to about 13 percent of the world's adult population, [218] with that figure growing to 16% by 2022, according to the World Health Organisation [219] The percentage of adults affected in the United States as of 2015–2016 is about 39.6% overall (37.9% of males and 41.1% of females).

HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

In older patients, emotional instability may be less evident, or depression may occur, and the symptoms and signs are manifestly circulatory. In many, the thyroid is not readily palpable. [4] Symptoms such as rapid heart rate, shortness of breath on exertion, and edema may predominate. Older patients also tend to have more weight loss and less ...
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
The impact of alcohol on weight-gain is contentious: some studies find no effect, [144] others find decreased [145] or increased effect on weight gain. Alcohol use increases the risk of chronic gastritis (stomach inflammation); [3] [146] it is one cause of cirrhosis, hepatitis, and pancreatitis in both its chronic and acute forms.
Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. [1] Other symptoms depend on the underlying cause. [2] Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema.
Symptoms are not specific, and diagnosis can be difficult unless patients present with clear indications for blood gas sampling. Symptoms may include palpitations, headache, altered mental status such as severe anxiety due to hypoxia, decreased visual acuity, nausea, vomiting, abdominal pain, altered appetite and weight gain, muscle weakness, bone pain, and joint pain.
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene ( HMPE ), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu . [ 1 ]
