Pills that are used for contraception have two techniques; the first technique is by preventing ovulation, or the releasing of eggs by the ovaries. The second technique is thickening cervical mucus, which prevents sperm from joining with an egg. To do that, there are two types of pills:

1-      Combination pills; they contain estrogen and progestin and used for the first technique.

2-      Progestin-only pills; it is used for the second technique.

In spite of the high effectiveness of the oral contraceptives — when used correctly — that reaches 97-98%, it does not protect against sexually transmitted infections, also, they should be used after a medical advice from the doctor and taking a prescription for them since they may increase the chance of developing blood clots in the legs, lungs, heart or brain for some women, especially who are over the age of 35 or that women who smoke.

Using birth control pills has some health benefits beside other bad side effects, it may protect against cancer of the ovaries, cancer of the lining of the uterus, ovarian cysts, and menstrual cramps, but, it may has other side effects such as weight gain or loss, bleeding between periods, nausea and sometimes vomiting, breast tenderness, and Depression.

The traditional birth control pills keep the interval between the menstrual cycle to 28 days, but, there are some types of birth control pills that used to suppress menstruation, they extends the interval to make the menstrual cycle only four times per year. However, there is greater chance to bleed between periods than with the traditional pill.

The Traditional way of CPR includes two steps; first step is forcefully pressing on the chest to stimulate the heart beating, after that, an artificial respiration is done in the second step by mouth-to-mouth rescue breathing. However, there is another device called automated external defibrillator (AED), which used to electrically stimulate the heart to restart working. There are special medicines that are used in the cases of stooping heart beating. Also, a tube can be put in the lung through mouth or noise to help the person to breathe by connecting the other side of the tube to a breathing machine. These techniques are done for 15 to 30 minutes when a heart attack occurs, Otherwise the person will immediately faints, and probably die in 5 to 10 minutes. If the dying patients suffer from advanced life-threatening illness, CPR may be useless; however, it may has a good effect for younger people or people who have better health. Anyway, CPR may be ineffective if it does not start within 5 to 10 minutes after heart attack. Also, patients may need to be put in a breathing machine after they survive by, applying CPR to them, to help them breathe for longer time.

It is important for anyone to be trained before trying to do CPR for patients. First-aid training course will be helpful to learn how to do CPR and to use the automatic external defibrillator. The wrong way doing CPE may complicate the problem, for example, high pressing on the chest may broke ribs, collapse lung or cause a sore chest. Medicines may be better choice for patients who are using breathing tubes. For patients who have more than one illness have less chance to survive after CPR. In some cases it may cause brain damage for the survived people.

causes:
The errecção results from a complex process involving the brain, hormones, pelvic nerves and blood vessels supplying the penis. The structures responsible for penile erectile mechanism are the corpora cavernosa, two cylindrical compartments involved in coat solid (albuginea). In parallel runs the body spongiform containing the urethra. In the excitement, the increased blood flow to the penis as well as reducing the drainage expands the corpora cavernosa.
Previously regarded as primarily a disease of psychological erectile dysfunction most often results from a physical cause, usually a chronic systemic disease, the side effect of treatment instituted or a combination of these factors.

In addition some worries happens when taking the cholinesterase inhibitors and anticholinergic medications together as they will resist each other and no one of them will be able to affect the body.

When cholinesterase inhibitors was clinically tested it showed little effects against  the functional and cognitive decline of people with Alzheimer’s disease, these types of medications works in a way that inhabits the breakdown of acetylcholine, which is responsible for sending signals to nervous system, unlike the anticholinergics which blocked the action of acetylcholine, according to these results we can understand that the two medication give adverse effects, so that it’s not approved to give these two medication at the same time to a person.

After this there was a study conducted over 5,625 patient who are 50 years old or more, these participants were prescribed to take cholinesterase inhibitors for almost 7-8 years, the results of the study were shocking, as people who were taking anticholinergics during the study plus one year before it until the study was ended, were either died or the patient left the health care system, as a result after the study which was the first to state death records, insurance was asking to pay for health care and nursing for people.

Researchers doing the studies found that:

• 37% of the people taking cholinesterase inhibitor also took at least one anticholinergic drug, and more than 11% were talking two or more, these results was the same as other studies of Medicare beneficiaries.
• The people who used both medications stayed for 3-4 months, but at the same time 25% stayed for more than one year.
• 23% of the participant were using anticholinergics who received cholinesterase inhibitor prescription, in addition 77% continued using them even after starting to take the cholinesterase inhibitor.
• The people who used both medication were less likely to enter a nursing home or to die than those taking only cholinesterase inhibitors.

A doctor of the researching team said that it’s was a good thing they didn’t see an association between simultaneous use of the two types of drugs and increased risk of death or nursing home placement.

It is stated in the first of two studies which is now available, and was published in British Journal of Nutrition journal, that there is no notable effect on function in the case of people who are 18-35 years old who undergo a study of taking one of two types of fish oil supplement containing omega-3for three months, but at the same time they found times of mental fatigue reduction and times of faster reaction in the brain behavior.

So according to the study it’s unlike people’s beliefs, the results showed that taking omega-3 or fish oil supplements is probably don’t have an immediate effect nor a measurable change in the mental performance in young adults who are healthy and have no diseases, and they say that is may be a result of the way these people perform at the mental peak or may be is due to a higher dose that is required to see a change also a longer testing period required to see the effect.

But in the second study conducted in this field it was found that taking DHA-rich fish oil over the same time period had a notable impact in increasing the blood flow to the areas which were actives while performing similar mental jobs.

In depending on these results the researchers said that these claims is probably to have later effects on life, since it’s recommended to eat meals of oily fish or taking omega-3 supplements, as it can be a way to prevent cognitive decline and dementia, as the blood flow increases to the brain it can be a method by which these things result.

And because the results of these studies says that the impact of fish supplements occur over the long term on older people, researchers are now thinking of doing investigations on this category ,means people 50-70 years old in order to make an evaluation of these supplement effect on their memory, mental performance and blood flow to the brain.
