Reading Glasses

When you reach the point of not being able to read up close without stretching your arms to the limit, you may need to consider single-vision reading glasses. Reading glasses come in two main styles: full frames, in which the entire lens is made in the reading prescription, and half-eyes, the smaller "Ben Franklin" style glasses that sit lower down on the nose.

Full reading glasses are suitable for people who spend a great deal of time concentrating on material close-up. If you try to look up and across the room through the reading lenses, everything appears blurry.

In contrast, half-eye reading glasses allow you to look down and through the lenses for near work, and up and over them to see in the distance. Generally, people who have never needed glasses in the past will start out with a pair of reading glasses rather than bifocals or no-line progressive lenses, which are usually a better choice if you have a need for distance as well as near correction.

Handy accessories for temporary use, such as an evening in a dimly lit restaurant, include tiny foldable readers that fit in pen-sized cases and magnifiers that hang around your neck like a pendant. You may have even seen plastic lenses mounted in credit card-sized holders that slip easily in a wallet — horrible for reading a book, but fine for those moments of desperation when you just want to know if the menu says "filet de boeuf" or "foie gras."

Also available are tinted reading glasses with UV protection for wearing outdoors in the sun; a popular type is the sunglass bifocal, with a nonprescription upper half for looking far away and a reading prescription in the lower half for close up.

Beware to High Blood

What is high blood pressure?

High blood pressure (HBP) or hypertension means high pressure (tension) in the arteries. Arteries are vessels that carry blood from the pumping heart to all the tissues and organs of the body. High blood pressure does not mean excessive emotional tension, although emotional tension and stress can temporarily increase blood pressure. Normal blood pressure is below 120/80; blood pressure between 120/80 and 139/89 is called "pre-hypertension", and a blood pressure of 140/90 or above is considered high.

The top number, the systolic blood pressure, corresponds to the pressure in the arteries as the heart contracts and pumps blood forward into the arteries. The bottom number, the diastolic pressure, represents the pressure in the arteries as the heart relaxes after the contraction. The diastolic pressure reflects the lowest pressure to which the arteries are exposed.

An elevation of the systolic and/or diastolic blood pressure increases the risk of developing heart (cardiac) disease, kidney (renal) disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke (brain damage). These complications of hypertension are often referred to as end-organ damage because damage to these organs is the end result of chronic (long duration) high blood pressure. For that reason, the diagnosis of high blood pressure is important so efforts can be made to normalize blood pressure and prevent complications.

It was previously thought that rises in diastolic blood pressure were a more important risk factor than systolic elevations, but it is now known that in people 50 years or older systolic hypertension represents a greater risk.

The American Heart Association estimates high blood pressure affects approximately one in three adults in the United States - 73 million people. High blood pressure is also estimated to affect about two million American teens and children, and the Journal of the American Medical Association reports that many are under-diagnosed. Hypertension is clearly a major public health problem.

How is the blood pressure measured?

The blood pressure usually is measured with a small, portable instrument called a blood pressure cuff (sphygmomanometer). (Sphygmo is Greek for pulse, and a manometer measures pressure.) The blood pressure cuff consists of an air pump, a pressure gauge, and a rubber cuff. The instrument measures the blood pressure in units called millimeters of mercury (mm Hg).

The cuff is placed around the upper arm and inflated with an air pump to a pressure that blocks the flow of blood in the main artery (brachial artery) that travels through the arm. The arm is then extended at the side of the body at the level of the heart, and the pressure of the cuff on the arm and artery is gradually released. As the pressure in the cuff decreases, a health practitioner listens with a stethoscope over the artery at the front of the elbow. The pressure at which the practitioner first hears a pulsation from the artery is the systolic pressure (the top number). As the cuff pressure decreases further, the pressure at which the pulsation finally stops is the diastolic pressure (the bottom number).

How is high blood pressure defined?

Blood pressure can be affected by several factors, so it is important to standardize the environment when blood pressure is measured. For at least one hour before blood pressure is taken, avoid eating, strenuous exercise (which can lower blood pressure), smoking, and caffeine intake. Other stresses may alter the blood pressure and need to be considered when blood pressure is measured.

Even though most insurance companies consider high blood pressure to be 140/90 and higher for the general population, these levels may not be appropriate cut-offs for all individuals. Many experts in the field of hypertension view blood pressure levels as a range, from lower levels to higher levels. Such a range implies there are no clear or precise cut-off values to separate normal blood pressure from high blood pressure. Individuals with so-called pre-hypertension (defined as a blood pressure between 120/80 and 139/89) may benefit from lowering of blood pressure by life style modification and possibly medication especially if there are other risk factors for end-organ damage such as diabetes or kidney disease (life style changes are discussed below).

For some people, blood pressure readings lower than 140/90 may be a more appropriate normal cut-off level. For example, in certain situations, such as in patients with long duration (chronic) kidney diseases that spill (lose) protein into the urine (proteinuria), the blood pressure is ideally kept at 130/80, or even lower. The purpose of reducing the blood pressure to this level in these patients is to slow the progression of kidney damage. Patients with diabetes (diabetes mellitus) may also benefit from blood pressure that is maintained at a level lower than 130/80. In addition, African Americans, who have an increased risk for developing the complications of hypertension, may decrease this risk by reducing their systolic blood pressure to less than 135 and the diastolic blood pressure to 80 mm Hg or less.

In line with the thinking that the risk of end-organ damage from high blood pressure represents a continuum, statistical analysis reveals that beginning at a blood pressure of 115/75 the risk of cardiovascular disease doubles with each increase in blood pressure of 20/10. This type of analysis has led to an ongoing "rethinking" in regard to who should be treated for hypertension, and what the goals of treatment should b

H1N1 VIRUS

influenza A virus

influenza A virus subtype H1N1, also known as A(H1N1), is a subtype of influenzavirus A and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans, including the strain(s) responsible for the 1918 flu pandemic which killed 50-100 million people worldwide. Less virulent H1N1 strains still exist in the wild today, worldwide, causing a small fraction of all influenza-like illness and a large fraction of all seasonal influenza. H1N1 strains caused roughly half of all flu infections in 2006.^[1] Other strains of H1N1 are endemic in pigs (swine influenza) and in birds (avian influenza).

In March to June of 2009, thousands of laboratory-confirmed infections and a number of deaths were caused by an outbreak of a new strain of H1N1.^[2]

TO PROTECT YOUR HEALTH

USE PROPER

Handwashing is the single most important procedure for preventing the spread of biological contamination. Despite this fact many laboratory personnel don't wash their hands properly. Here are some handwashing tips and procedures for your use.

1. Consider the sink, including the faucet controls, contaminated.

2. Avoid touching the sink.

3. Turn water on using a paper towel and then wet your hands and wrists.

4. Work soap into a lather.

5. Vigorously rub together all surfaces of the lathered hands for 15 seconds. Friction helps remove dirt and microorganisms. Wash around and under rings, around cuticles, and under fingernails

6. Rinse hands thoroughly under a stream of water. Running water carries away dirt and debris. Point fingers down so water and contamination won't drip toward elbows.

7. Dry hands completely with a clean dry paper towel.

8. Use a dry paper towel to turn faucet off.

9. To keep soap from becoming a breeding place for microorganisms, thoroughly clean soap dispensers before refilling with fresh soap.

10. When handwashing facilities are not available at a remote work site, use an appropriate antiseptic hand cleaner or antiseptic towelettes. As soon as possible, rewash hands with soap and running water.
