Insights: In a Man’s Offspring, a Clue to Prostate Cancer

[amazon_link asins=’1455504181,0988710501,B06XPW2FD4,061514022X’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’de3769b0-5ee3-11e7-8611-3b99f75e2814′]

Men who have only daughters may be at greater risk for prostate cancer than those who have at least one son, a new study reports, and the reason may be an alteration in the Y chromosome, the male sex chromosome.

Prostate Cancer in Fathers With Fewer Male Offspring: the Jerusalem Perinatal Study Cohort (Journal of the National Cancer Insitute)Researchers recorded the sex of the offspring of 38,934 Israeli men who had children from 1964 to 1976, and then followed the fathers through 2005, during which time 712 developed prostate cancer. After adjusting for other variables, they found that those with no sons were almost one and a half times as likely to have developed the disease as those with at least one son. The more daughters they had without having any sons, the more their risk increased.

Because the inability to produce male children is associated with alterations in the Y chromosome, this suggests that the chromosome may be involved in prostate cancer risk.
Still, said Dr. Susan Harlap, the lead author and a professor of clinical epidemiology at Columbia,  The main reason a man has male or female children, even in runs of one sex, is chance. She said she did not recommend extra prostate screening for men with only daughters.

The researchers acknowledge that their study, published Jan. 3 in The Journal of the National Cancer Institute, gathered no information about family history of prostate cancer. In addition, they studied a specific group of men, and it may not be possible to generalize the results to other populations.

Prostate cancer is a huge mystery,  Dr. Harlap said, not like lung or colon cancer, where we have a pretty good idea about causes. Our study gives a hint to look at the Y chromosome, and maybe the X chromosome, too, while you  are at it.

You can exert control your bladder

[amazon_link asins=’B01DR309Q6,B00SLQHQSO,B0030ZLP1A,B008A98RJY,B01KXVF6WW,B00KJC85O2,B014GMBDQ2,B013EHOMTK,B00KAP0HQW’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’c827b3d5-ffd9-11e6-a8fa-4fd104827b8f’]

Incontinence should not be summarily dismissed as an inevitable consequence of ageing. Basic tests should be done to rule out any correctable cause Dr Gita Mathai

The urge to urinate is under voluntary control and can be suppressed until a suitable opportunity appears…...click & see
Coughing, sneezing and laughing are normal, unavoidable day-to-day activities which cause a transient increase in intra abdominal pressure. Young people are unaffected, but in 25 per cent of women and 15 per cent of men above 65 years of age, the actions involuntarily produce embarrassing dribbling of urine or stress incontinence.

The bladder can normally accommodate 500 ml of urine. The urge to void appears when it contains 200 ml. If there is an obstruction to free voiding due to an enlarged prostate, an uterine or ovarian tumour, or even constipation, the bladder becomes overfilled. The urine can then leak from the full bladder in small quantities leading to overflow incontinence.

The urge to urinate is under voluntary control; it can be suppressed until a suitable opportunity appears. Hyperactivity of the muscles in the bladder can allow urine to escape even if the bladder is not overfilled, as soon as the urge is felt, before reaching the toilet. This can occur with increasing age especially if the person also has diabetes, stroke, dementia or Parkinson’s disease. It may be secondary to stones in the bladder or an urinary tract infection.

Incontinence is commoner in women. Statistics show that 50 per cent of women have occasional urinary incontinence and 10 per cent have frequent incontinence. The incidence increases until 20 per cent of women over the age of 75 years experience daily urinary incontinence.

This is because anatomically, women have a shorter urethra and weaker pelvic muscles. Damage can also occur as a result of childbirth. The onset of menopause decreases the levels of the female hormones, causing atrophy of the vaginal mucosa and loss of pelvic muscle tone. This causes the bladder to protrude into the vaginal space increasing incontinence.

Incontinence should not be summarily dismissed as an inevitable consequence of ageing. Basic tests should be done to rule out any correctable cause .

A physical pelvic examination to rule out abnormalities of the pelvic organs.

Blood tests to rule out diabetes.

Urinalysis and culture if infection is suspected.

A few simple lifestyle interventions can help to reduce stress incontinence .

Reduction in weight, such that the BMI (body mass index) is around 25.

Control over volume of fluids drunk and reduction in the quantity if it is more than two-three litres per day.

Prevention of constipation as hard faecal matter acts as an obstruction that aggravates stress incontinence.

Regular voiding, so that the bladder is never too full.

Women can increase the strength and tone of the pelvic muscles and re-train their pelvic musculature with Keegle’s exercises.

To perform these exercises correctly, the right muscles first need to be located. To do this, stop and start urination without using the stomach, leg or buttock muscles.

Squeeze these muscles. Hold for a count of 10. Relax for a count of 10. Do this 20 times, three-four times a day.

Alternatively, each time you go to the toilet to pass urine, stop and restart the process voluntarily several times, so that you exert control over the action.

The bladder can also be re-trained by consciously increasing the time between voiding.

Within four weeks, 70 per cent of women markedly improve and 15 per cent are permanently cured. The benefit disappears within a few days if the exercises are not consciously continued.

Medications can be used as an adjuvant to exercises. Tricyclic antidepressants and other groups of medications can be used to treat stress incontinence in patients with mild-to-moderate symptoms. Fifty per cent of the people respond favourably.

Oestrogen replacement, either taken orally as part of HRT (hormone replacement therapy) or applied locally in the vagina as a cream, improves urinary frequency, urgency, stress incontinence and burning in postmenopausal women.

Surgical treatment can be considered after a thorough evaluation, examination and investigation to determine the exact cause of the urinary incontinence. Surgery can help by correcting the anatomical abnormalities, supporting the bladder and urethra in the proper position, and tightening the urethral sphincter. This helps to achieve voluntary control. Surgery has a 75-95 per cent cure rate if the patients are carefully selected. The procedure involves anaesthesia and hospital stay and is not totally risk free. The eventual outcome is unsatisfactory in people .

With prior surgical failures

If there are other genital or urinary problems

In case of other complicating diseases that may prevent adequate healing or make the technical aspects of the surgery more difficult.

As age advances, the bladder capacity reduces; the urinary stream becomes weaker, and visits to the toilet more frequent. This does not, however, mean that urinary frequency, urgency and stress incontinence have to be accepted as an inevitable part of ageing.

Most incontinence problems, provided they do not require corrective surgery, can be cured by motivation, weight loss, dedicated re-training of the bladder and pelvic exercises.

Botanical Name :Momordica charantia
Family: Cucurbitaceae
Genus: Momordica
Species: M. charantia
Kingdom: Plantae
Order: Cucurbitales

Common Names:Bitter melon, bitter gourd, bitter squash or balsam-pear  in English, has many other local names. Goya  from Okinawan and karela from Sanskrit are also used by English-language speakers.

Habitat :  Momordica charantia is a tropical and subtropical vine of the family Cucurbitaceae, widely grown for edible fruit, which is among the most bitter of all vegetables. English names for the plant and its fruit include bitter melon or bitter gourd (translated from Chinese: ??; pinyin: kugua). The original home of the species is not known, other than that it is a native of the tropics. It is widely grown in India, South Asia, The Philippines, Southeast Asia, China, Africa and the Caribbean.

Also known as Ku gua, the herbaceous, tendril-bearing vine grows to 5 m. It bears simple, alternate leaves 4-12 cm across, with 3-7 deeply separated lobes. Each plant bears separate yellow male and female flowers.

Description: This herbaceous, tendril-bearing vine grows to 5 m. It bears simple, alternate leaves 4–12 cm across, with three to seven deeply separated lobes. Each plant bears separate yellow male and female flowers. In the Northern Hemisphere, flowering occurs during June to July and fruiting during September to November…..CLICK & SEE

The fruit has a distinct warty exterior and an oblong shape. It is hollow in cross-section, with a relatively thin layer of flesh surrounding a central seed cavity filled with large, flat seeds and pith. The fruit is most often eaten green, or as it is beginning to turn yellow. At this stage, the fruit’s flesh is crunchy and watery in texture, similar to cucumber, chayote or green bell pepper, but bitter. The skin is tender and edible. Seeds and pith appear white in unripe fruits; they are not intensely bitter and can be removed before cooking.

As the fruit ripens, the flesh (rind) becomes somewhat tougher and more bitter, and many consider it too distasteful to eat. On the other hand, the pith becomes sweet and intensely red; it can be eaten uncooked in this state, and is a popular ingredient in some Southeast Asian salads.

When the fruit is fully ripe, it turns orange and mushy, and splits into segments which curl back dramatically to expose seeds covered in bright red pulp.

Varieties:
Bitter melon comes in a variety of shapes and sizes. The cultivar common to China is 20–30 cm long, oblong with bluntly tapering ends and pale green in color, with a gently undulating, warty surface. The bitter melon more typical of India has a narrower shape with pointed ends, and a surface covered with jagged, triangular “teeth” and ridges. It is green to white in color. Between these two extremes are any number of intermediate forms. Some bear miniature fruit of only 6–10 cm in length, which may be served individually as stuffed vegetables. These miniature fruit are popular in Bangladesh, India (common name ‘Karela’), Pakistan, Nepal and other countries in South Asia. The sub-continent variety is most popular in Bangladesh and India.

Bitter melon is commonly used as a vegetable in tropical areas such as East Africa, Asia, the Caribbean, and South America. The plant gets its name from the bitter taste of its fruit and juice; however, cooking it with the appropriate spices can reduce the bitterness. In addition to being a food source, bitter melon is employed as an herbal remedy in many parts of the world. While the seeds, leaves and vines of bitter melon may all be used, the fruit is used most often for medicinal purposes.

At lease three types of compounds in bitter melon are believed to lower blood sugar, which can benefit people with diabetes mellitus. It is still unclear whether these compounds work together or individually, but several controlled clinical studies have confirmed that bitter melon is beneficial in controlling the symptoms of diabetes.

Test-tube studies have also shown that two proteins found in bitter melon — alpha-momorcharin and beta-momorcharin — inhibit the AIDS virus. However, these studies have not been conducted in humans.

Culinary uses:
Bitter melons are seldom mixed with other vegetables due to the strong bitter taste, although this can be moderated to some extent by salting and then washing the cut melon before use.

Bitter melon is often used in Chinese cooking for its bitter flavor, typically in stir-fries (often with pork and douchi), soups, and also as tea.

It is also a popular vegetable in Indian and Pakistani cooking, where it is often prepared with potatoes and served with yogurt on the side to offset the bitterness. Bitter melon fried in oil and then stuffed with other spicy ingredients is very popular in Andhra Pradesh, a south Indian state.

Bitter melon is rarely used in mainland Japan, but is a significant component of Okinawan cuisine.

In Vietnam, raw bitter melon slices consumed with dried meat floss and bitter melon soup with shrimp are popular dishes.

It is prepared into various dishes in the Philippines, where it is known as ampalaya. Ampalaya may also be stir-fried with ground beef and oyster sauce, or with eggs and diced tomato. A very popular dish from the Ilocos region of the Philippines, pinakbet, consists mainly of bitter melons, eggplant, okra, string beans, tomatoes, lima beans, and other various regional vegetables stewed with a little bagoong-based stock.

The young shoots and leaves may also be eaten as greens; in the Philippines, where bitter melon leaves are most commonly consumed, they are called dahon (leaves) ng ampalaya. The seeds can also be eaten, and give off a sweet taste, but have been known to cause vomiting and stomach upset.

Medicinal uses:
Bitter melons have been used in various Asian traditional medicine systems for a long time . Like most bitter-tasting foods, bitter melon stimulates digestion. While this can be helpful in people with sluggish digestion, dyspepsia, and constipation, it can sometimes make heartburn and ulcers worse. The fact that bitter melon is also a demulcent and at least mild inflammation modulator, however, means that it rarely does have these negative effects, based on clinical experience and traditional reports.

Perhaps the best substantiated use to date is that of bitter melon for people with diabetes mellitus. Several preliminary (non-randomized, non-blinded) clinical trials suggest this benefit, though controlled trials are necessary for confirmation . In the Philippines, bitter melon tea is used in blood sugar control for poor people as exemplified in the very successful Operation Diabetes . For a detailed review of studies involving bitter melon and diabetes, see Abascal and Yarnell 2005.

In ayurvedic medicine, bitter melon is popularly seen as a “plant-insulin.” It has been demonstrated that bitter melon contains a protein similar to bovine insulin, sometimes referred to as p-insulin or polypeptide-p (Baldwa, et al. 1977). When purified and injected subcutaneously into patients with insulin-dependent diabetes mellitus (IDDM), it acted very similar to slow-acting animal insulins and was able to sustain patients . One child in this small study who previously had many side effects from bovine insulin was able to use p-insulin exclusively for 5 months with no sign of problems. This represents the potential for a vegetarian alternative to animal insulin for patients with IDDM, as well as a potentially more sustainable source of insulin, and should be further developed. It is not possible to substitute eating bitter melon for taking insulin.

Though it has been claimed that bitter melon’s bitterness comes from quinine, no evidence could be located supporting this claim. Bitter melon is traditionally regarded by Asians, as well as Panamanians and Colombians, as useful for preventing and treating malaria. Laboratory studies have confirmed that various species of bitter melon have anti-malarial activity, though human studies have not yet been published .

Laboratory tests suggest that compounds in bitter melon might be effective for treating HIV infection . As most compounds isolated from bitter melon that impact HIV have either been proteins or glycosproteins (lectins), neither of which are well-absorbed, it is unlikely that oral intake of bitter melon will slow HIV in infected people. It is possible oral ingestion of bitter melon could offest negative effects of anti-HIV drugs, if a test tube study can be shown to be true in people . In one preliminary clinical trial, an enema form of a bitter melon extract showed some benefits in people infected with HIV (Zhang 1992). Clearly more research is necessary before this could be recommended.

The other realm showing the most promise related to bitter melon is as an immunomodulator. One clinical trial found very limited evidence that bitter melon might improve immune cell function in people with cancer, but this needs to be verified and amplified in other research . If proven correct this is another way bitter melon could help people infected with HIV


How much bitter melon should I take?

For those who can withstand the bitter taste, many herbalists recommend eating one small melon; 100 millileters of a bitter melon decoction; or two ounces of fresh bitter melon juice per day. For people who cannot stand the taste, some practitioners recommend bitter melon tinctures (five millileters, two or three times per day).

What forms of bitter melon are available?

Fresh bitter melon and bitter melon juice can be found at many specialty stores and Asian markets. Bitter melon extracts and tinctures can be found at some health food stores.

What can happen if I take too much bitter melon? Are there any interactions I should be aware of? What precautions should I take?

Excessive amounts of bitter melon juice may cause abdominal pain and diarrhea. In addition, patients with hypoglycemia should avoid bitter melon, because it could theoretically worsen their condition.

At present, there are no well-known drug interactions with better melon. However, make sure to consult with a health care provider before taking bitter melon (or any other dietary supplement).

A Colorful Way to Reduce the Risk of Alzheimer’s

Alzheimer’s disease, a common form of dementia that currently affects 13 million people across the globe, may start losing the battle because of a new enemy   fruit and vegetable juice. The results of a new study published in the September 2006 edition of The Journal of American Medicine suggest that the antioxidant polyphenols found naturally in fruits and vegetables can reduce the risk of the onset of Alzheimer’s.

A group of 1,836 dementia-free Japanese-Americans in the Seattle area were chosen for the study. Information was collected on their consumption of fruit and vegetable juice with the use of a questionnaire and was assessed every two years for up to 10 years. The results showed that individuals who drank juice three or more times a week were 76 percent less likely to develop the symptoms of Alzheimer’s compared to those who drank less than one serving a week.

The only limitation of the study was that specific juices were not found to be more effective than others. This may lead to a more precise study of individual vegetable and fruit juices. To find out more about the benefits of antioxidants and other compounds found in fruits and vegetables, talk to your chiropractor and visit www.chiroweb.com/find/tellmeabout/nutrients.html.

Considering Others

Reaffirming Our Integrity
Every thought we think and every action we take has an effect on the world around us. To be aware of this is to be conscious of our impact on the people in our lives. Sometimes we just want to do what we want to do, but considering the full ramifications of our actions can be an important part of our spiritual growth and awareness. At first, being more conscious requires effort, but once we have made it a habit, it becomes second nature. The more we practice this awareness of others, the more we find ourselves in easy alignment with our integrity.

Our thoughts are an important place to begin this practice because our thoughts are the seeds of our actions. It is not necessary or beneficial to obsessively monitor all our thoughts, but we can perhaps choose one thought or action per day and simply notice if we are in alignment with this experience of integrity. For example, we may find ourselves replaying a negative encounter with someone in our minds. We may think that this doesn’t affect the person about whom we are thinking, but the laws of energy tell us that it does. When we hold someone negatively in our minds, we risk trapping them in negativity. If we were this person, we might wish for forgiveness and release. We can offer this by simply letting go of the negative thought and replacing it with a wish for healing on that person’s behalf.

With regard to our actions, we may have something difficult to express to someone. Taking the time to consider how we would feel if we were in his or her shoes will enable us to communicate more sensitively than we would if we just expressed ourselves from our own perspective. When we modify our approach by taking someone else’s feelings into account, we bring benefit to that person and ourselves equally. The more we do this, the more we reaffirm our integrity and the integrity of our relationship to the world.
