The prostate is can be a troublesome little gland. It is prone to painful infections and inflammation (prostatitis), enlargement that interferes with urination (benign prostatic hyperplasia, or BPH), and cancer. Prevention is the best medicine, something exercise can help with. Exercise has also been shown to help treat various prostate-related conditions.

Although relatively few studies have looked at the impact of exercise specifically on prostate health, the ones that have suggest that regular physical activity can be good for this walnut-sized gland.

BPH prevention. In the ongoing Harvard-based Health Professionals Follow-up Study, men who were more physically active were less likely to suffer from BPH. Even low- to moderate-intensity physical activity, such as walking regularly at a moderate pace, yielded benefits.

Prostatitis treatment. Italian researchers conducted a randomized controlled trial (considered the gold standard of medical research) in men with chronic prostatitis. Those in the aerobic exercise group walked briskly three times a week. A comparison group did non-aerobic exercise (leg lifts, sit ups, and stretching) three times a week. At the end of 18 weeks, men in both groups felt better, but those doing aerobic exercises reported less prostatitis pain, less anxiety and depression, and better quality of life.

Prostate cancer progression. In a study of more than 1,400 men diagnosed with early-stage prostate cancer, men who walked briskly (not leisurely) for at least three hours a week were 57% less likely to have their cancer progress than those who walked less often and less vigorously. In an analysis from the Health Professionals Follow-up Study, men diagnosed with localized prostate cancer who engaged in vigorous activity at least three hours each week had a 61% lower chance of dying from the illness, compared to men who engaged in vigorous activity less than one hour a week.

How to get started

A well-rounded exercise program that includes a half-hour of physical activity on all or most days of the week delivers solid health benefits. And you needn’t perform this activity all at once; you can break it up into three 10-minute segments.

As always, talk to your doctor before beginning an exercise program. He or she can help you develop a routine based on your health and fitness level.

If you have diabetes — or for that matter, nearly any other chronic illness — exercise is one of the most powerful tools that can help you control your weight and blood sugar. And it can help you feel great, too.

The list of exercise benefits is long. Exercise helps control weight, lowers blood pressure, reduces harmful LDL cholesterol and triglycerides, raises healthy HDL cholesterol, strengthens muscles and bones, and reduces anxiety. Exercise can help regulate blood sugar and increase the body’s sensitivity to insulin. Both are important for people with diabetes.

Many studies have documented that exercise is a strong ally in treating diabetes. Here are a few examples:

• All forms of exercise — aerobic, resistance, and a combination of both — have been shown to be equally good at lowering HbA1c values.

• Resistance training and aerobic exercise both helped to lower insulin resistance in previously sedentary older adults at risk for diabetes. Combining the two was better than either one alone.

• People with diabetes who walked at least two hours a week were less likely to die of heart disease than their sedentary counterparts, and those who exercised three to four hours a week cut their risk even more.

• Women with diabetes who spent at least four hours a week doing moderate or vigorous exercise had a 40% lower risk of developing heart disease than those who didn’t exercise.

If you have diabetes, generally it is best to exercise one to three hours after eating, when your blood sugar level is likely to be higher. If you use insulin, be sure to test your blood sugar before exercising. If it is below 100 mg/dL, eat a piece of fruit or have a small snack. This will bump your blood sugar up and help you avoid hypoglycemia. Test again 30 minutes after your snack to be sure your blood sugar level is stable. It’s also a good idea to check your blood sugar after any particularly grueling workout or activity. If you’re taking insulin, your risk of developing hypoglycemia may be highest six to 12 hours after exercising. Experts also caution against exercising if your blood sugar is too high (over 250).

A medical alert bracelet should be part of your workout wardrobe. It should indicate that you have diabetes and whether you take insulin. Also, keep hard candy or glucose tablets with you while exercising in case your blood sugar takes a nosedive.

Seasickness caused by boat motion can be a serious problem for sailors. Not only does the sick person feel terrible and become incapacitated, and therefore a problem too for others on a shorthanded boat, but the dehydration that may result from repeated vomiting can become a medical issue. Therefore it's important to know how to prevent seasickness.

About 90% of people will experience seasickness or motion sickness at some point in their lives. If you're new to sailing, or have ever experienced nausea or dizziness on a boat, it's worthwhile to take steps early to prevent seasickness. Once seasickness occurs, it's too late to do much more than cope with it as best you can.

Even with many medical studies and hundreds of years of experimenting with how to prevent seasickness, no one method or medication has been developed that works for everyone. But various methods do work for different people, so it's mostly an issue of taking the problem seriously and trying to determine what will work best for you.

Prevention, Not Cure

Seasickness prevention remedies fall into four general categories: medications, food and drink prescriptions, wrist bands, and behavior tips:

Medications

Note: if you have a health condition or are taking other medications, talk to your doctor before starting any new medication, to ensure the drugs do not produce a negative interaction.

Food and Drink

Wrist Bands

Behavior Tips

Remember to Start Early!

In most cases you should begin the remedy well before beginning to experience any signs or symptoms of seasickness. Usually that means before getting on the boat. But if you start out on a calm day and boat motion later starts to pick up, it's better late than never. Seasickness often begins with general feelings of drowsiness-the first sign may be yawning. Don't wait!

Boston, MA – Men who do weight training regularly—for example, for 30 minutes per day, five days per week—may be able to reduce their risk of type 2 diabetes by up to 34%, according to a new study by Harvard School of Public Health (HSPH) and University of Southern Denmark researchers. And if they combine weight training and aerobic exercise, such as brisk walking or running, they may be able to reduce their risk even further—up to 59%.

This is the first study to examine the role of weight training in the prevention of type 2 diabetes. The results suggest that, because weight training appears to confer significant benefits independent of aerobic exercise, it can be a valuable alternative for people who have difficulty with the latter.  

The study will be published online in Archives of Internal Medicine on August 6, 2012. 

“Until now, previous studies have reported that aerobic exercise is of major importance for type 2 diabetes prevention,” said lead author Anders Grøntved, visiting researcher in the Department of Nutrition at HSPH and a doctoral student in exercise epidemiology at the University of Southern Denmark. “But many people have difficulty engaging in or adhering to aerobic exercise. These new results suggest that weight training, to a large extent, can serve as an alternative to aerobic exercise for type 2 diabetes prevention.” 

Type 2 diabetes is a major public health concern and it’s on the rise. An estimated 346 million people worldwide have type 2 diabetes, and diabetes-related deaths are expected to double between 2005 and 2030, according to the World Health Organization. More than 80% of these deaths occur in low- and middle-income countries. 

The researchers, including senior author Frank Hu, professor of nutrition and epidemiology at HSPH, followed 32,002 men from the Health Professionals Follow-up Study from 1990 to 2008. Information on how much time the men spent each week on weight training and aerobic exercise came from questionnaires they filled out every two years. The researchers adjusted for other types of physical activity, television viewing, alcohol and coffee intake, smoking, ethnicity, family history of diabetes, and a number of dietary factors. During the study period, there were 2,278 new cases of diabetes among the men followed. 

The findings showed that even a modest amount of weight training may help reduce type 2 diabetes risk. The researchers categorized the men according to how much weight training they did per week—between 1 and 59 minutes, between 60 and 149 minutes, and at least 150 minutes—and found that the training reduced their type 2 diabetes risk by 12%, 25%, and 34%, respectively, compared with no weight training. Aerobic exercise is associated with significant benefits as well, the researchers found—it reduced the risk of type 2 diabetes by 7%, 31%, and 52%, respectively, for the three categories above. 

The researchers also found that the combination of weight training and aerobic exercise confers the greatest benefits: Men who did more than 150 minutes of aerobics as well as at least 150 minutes of weight training per week had a 59% reduced risk of type 2 diabetes. 

Grøntved said that further research is needed to confirm the results of the study as well as to analyze whether or not the findings can be generalized to women. 

“This study provides clear evidence that weight training has beneficial effects on diabetes risk over and above aerobic exercise, which are likely to be mediated through increased muscle mass and improved insulin sensitivity,” said Hu. “To achieve the best results for diabetes prevention, resistance training can be incorporated with aerobic exercise.” 

Other HSPH authors included Eric Rimm, associate professor in the Departments of Epidemiology and Nutrition, and Walter Willett, Frederick John Stare Professor of Epidemiology and Nutrition and chair of the Department of Nutrition. 

Support for the study was provided by the National Institutes of Health (DK58845 and CA55075).

Cellulite and Cellulitus are not the same or related conditions

Cellulitis facts

• Cellulitis is a spreading bacterial infection of the skin and tissues beneath the skin.

• Staphylococcus and Streptococcus are the types of bacteria that are usually responsible for cellulitis, although many types of bacteria can cause the condition.

• Sometimes cellulitis appears in areas where the skin has broken open, such as the skin near ulcers or surgical wounds.

• Cellulitis is not contagious.

• Cellulitis is treated with oral or intravenous antibiotics.

What is cellulitis?

Cellulitis is a bacterial infection of the skin and tissues beneath the skin. Unlike impetigo, which is a very superficial skin infection, cellulitis is an infection that also involves the skin's deeper layers: the dermis and subcutaneous tissue. The main bacteria responsible for cellulitis are Streptococcus and Staphylococcus ("staph"), the same bacteria that can cause impetigo. MRSA (methicillin-resistant Staph aureus) can also cause cellulitis. Sometimes, other bacteria (for example, Hemophilus influenzae, Pneumococcus, and Clostridium species) may cause cellulitis as well.

Cellulitis is fairly common and affects people of all races and ages. Men and women appear to be equally affected. Although cellulitis can occur in people of any age, it is most common in middle-aged and elderly people.

What are cellulitis symptoms and signs?

Cellulitis usually begins as a small area of tenderness, swelling, and redness that spreads to adjacent skin. As this red area begins to enlarge, the affected person may develop a fever, sometimes with chills and sweats, tenderness, and swollen lymph nodes ("swollen glands") near the area of infected skin.

Where does cellulitis occur?

Cellulitis may occur anywhere on the body, but the lower leg is the most common site of the infection (particularly in the area of the tibia or shinbone and in the foot; see the illustration below), followed by the arm, and then the head and neck areas. In special circumstances, such as following surgery or trauma wounds, cellulitis can develop in the abdomen or chest areas. People with morbid obesity can also develop cellulitis in the abdominal skin. Special types of cellulitis are sometimes designated by the location of the infection. Examples include periorbital (around the eye socket) cellulitis, buccal (cheek) cellulitis, facial cellulitis, and perianal cellulitis.

What does cellulitis look like?

The signs of cellulitis include redness, warmth, swelling, tenderness, and pain in the involved tissues. Any skin wound or ulcer that exhibits these signs may be developing cellulitis.

Other forms of noninfected inflammation may mimic cellulitis. People with poor leg circulation, for instance, often develop scaly redness on the shins and ankles; this is called "stasis dermatitis" and is often mistaken for the bacterial infection of cellulitis.

What are cellulitis risk factors?

Most commonly, cellulitis develops in the area of a break in the skin, such as a cut, small puncture wound, or insect bite. In some cases when cellulitis develops without an apparent skin injury, it may be due to microscopic cracks in the skin that is inflamed or irritated. It may also appear in the skin near ulcers or surgical wounds.

In other circumstances, cellulitis occurs where there has been no skin break at all, such as with chronic leg swelling (edema). A preexisting skin infection, such as athlete's foot (tinea pedis) or impetigo can predispose to the development of cellulitis. Likewise, inflammatory conditions of the skin like eczema, psoriasis, or skin damage caused by radiation therapy can lead to cellulitis.

People who have diabetes or conditions that compromise the function of the immune system (for example, HIV/AIDS or those receiving chemotherapy or drugs that suppress the immune system) are particularly prone to developing cellulitis.

Conditions that reduce the circulation of blood in the veins or that reduce circulation of the lymphatic fluid (such as venous insufficiency, obesity, pregnancy, or surgeries) also increase the risk of developing cellulitis.

What causes cellulitis?

The majority of cellulitis infections are caused by infection with either strep (Streptococcus) or staph (Staphylococcus) bacteria.

The most common bacteria that cause cellulitis are beta-hemolytic streptococci (groups A, B, C, G, and F). A form of rather superficial cellulitis caused by strep is called erysipelas and is characterized by spreading hot, bright red circumscribed area on the skin with a sharp, raised border. Erysipelas is more common in young children. The so-called "flesh-eating bacteria" are, in fact, also a strain of strep bacteria that can sometimes rapidly destroy tissues underneath the skin.

Staph (Staphylococcus aureus), including methicillin-resistant strains (MRSA), is another common type of bacteria that causes cellulitis. There is a growing incidence of community-acquired infections due to methicillin-resistant S. aureus (MRSA), a particularly dangerous form of this bacteria that is resistant to many antibiotics, including methicillin, and is therefore more difficult to treat.

Cellulitis can be caused by many other types of bacteria. In children under 6 years of age, H. flu (Hemophilus influenzae) bacteria can cause cellulitis, especially on the face, arms, and upper torso. Cellulitis from a dog or cat bite or scratch may be caused by the Pasteurella multocida bacteria, which has a very short incubation period of only four to 24 hours. Aeromonas hydrophilia, Vibrio vulnificus, and other bacteria are causes of cellulitis that develops after exposure to freshwater or seawater. Pseudomonas aeruginosa is another type of bacteria that can cause cellulitis, typically after a puncture wound.

Is cellulitis contagious?

Cellulitis is not contagious because it is an infection of the skin's deeper layers (the dermis and subcutaneous tissue), and the skin's top layer (the epidermis) provides a cover over the infection. In this regard, cellulitis is different from impetigo, in which there is a very superficial skin infection that can be contagious.

How is cellulitis diagnosed, and what is the treatment for cellulitis?

First, it is crucial for the doctor to distinguish whether or not the inflammation is due to an infection. The history and physical exam can provide clues in this regard, as can sometimes an elevated white blood cell count. A culture for bacteria may also be of value, but in many cases of cellulitis, the concentration of bacteria may be low and cultures fail to demonstrate the causative organism. In this situation, cellulitis is commonly treated with antibiotics that are designed to eradicate the most likely bacteria to cause the particular form of cellulitis.

When it is difficult or impossible to distinguish whether or not the inflammation is due to an infection, doctors sometimes treat with antibiotics just to be sure. If the condition does not respond, it may need to be addressed by different methods dealing with types of inflammation that are not infected. For example, if the inflammation is thought to be due to an autoimmune disorder, treatment may be with a corticosteroid.

Antibiotics, such as derivatives of penicillin or other types of antibiotics that are effective against the responsible bacteria, are used to treat cellulitis. If the bacteria turn out to be resistant to the chosen antibiotics, or in patients who are allergic to penicillin, other appropriate antibiotics can be substituted. Sometimes the treatment requires the administration of intravenous antibiotics in a hospital setting, since oral antibiotics may not always provide sufficient penetration of the inflamed tissues to be effective. In certain cases, intravenous antibiotics can be administered at home.

In all cases, physicians choose a treatment based upon many factors, including the location and extent of the infection, the type of bacteria causing the infection, and the overall health status of the patient.

Can cellulitis be prevented?

Under some circumstances, cellulitis can be prevented by proper hygiene, treating chronic swelling of tissues (edema), care of wounds or cuts. In other cases, microscopic breaks in the skin may not be apparent and infection may develop. In general, cellulitis in a healthy person with an intact immune system is preventable by avoiding skin surface wounds. In people with predisposing conditions (see above) and/or weakened immune systems, cellulitis may not always be preventable.

What is the outlook/prognosis for cellulitis?

Cellulitis is a treatable condition, but antibiotic treatment is necessary to eradicate the infection and avoid spread of the infection. Most cellulitis can be effectively treated with oral antibiotics at home. Sometimes hospitalization and intravenous antibiotics are required if oral antibiotics are not effective. If not properly treated, cellulitis can occasionally spread to the bloodstream and cause a serious bacterial infection of the bloodstream that spreads throughout the body (sepsis).
