Researchers found that nicotine, the addictive component in cigarettes, “fool” the brain and memory to create associations between environmental cues and smoking behavior. This may explain why former smokers miss when lighting a cigarette in a bar or after eating.

The findings of researchers from Baylor College of Medicine published in the September 10 edition of the journal Neuron.

“Our brain normally establishes these associations between things that give support to our existence and environmental signals so that we have behaviors that lead us to have successful lives. The brain sends a signal of reward when we act in a way that contributes to our welfare “said co-author, Dr. John A. Dani, professor of neuroscience at BCM, in a press release from the university. “However, nicotine usurps this subconscious learning process in the brain, so we started to behave as if smoking was a positive action.”

Dani said that environmental events associated with smoking can be converted into tracks that stimulate craving. This information could include alcohol, a meal with friends or even the way home from work.

Dani and Dr. Jianrong Tang, instructor of neuroscience at BCM and co-author of the report, recorded the brain activity of rats during exposure to nicotine.

The rats were allowed to wander through a device that had two compartments. In a magazine, receiving nicotine. And on the other, obtained a saline solution. The researchers recorded the amount of time that mice spent in each compartment and brain activity in the hippocampus, a brain area that creates the reports.

“The change in brain activity was amazing,” said Dani. “Compared with injections of saline, nicotine strengthened neural connections, sometimes up to 200 percent. The strengthening of these connections emphasizes the formation of new memories.”

Dani said that understanding the mechanisms that create memory could have implications for future research and treatment of memory disorders such as Alzheimer’s disease and in disorders of dopamine signaling, such as Parkinson’s disease.

Experts have found that nicotine activates a molecular receptor that is involved in the processes of inflammation and pain. This receptor, called TRPA1, is located in the nerve endings in the skin, as explained in the latest issue of the journal Nature Neuroscience.

The work, which has been tested in mice, indicates that activation of this receptor, an excitatory ion channel, may be responsible for the irritation produced by nicotine in anti smoking therapies when applied locally by nasal sprays or using patches over skin.

CSIC researcher Felix Viana of the Church said that “it was thought that the irritation produced by nicotine was due solely to stimulation of nicotine receptors already known.” “We – he continued – we have shown that nicotine can directly activate TRPA1 protein, which acts as a trigger of neuronal signals that transmit sensations of burning and pain.”

Researchers also have found that mice lacking the TRPA1 protein present no further irritation after administering intranasal nicotine.

“We have shown that nicotine has an irritating effect similar to that produced by other substances activating TRPA1, including mustard, onion, garlic, and emissions from the tailpipes of cars. In the future, this finding could be useful for developing new therapies against smoking, having fewer adverse effects, “said Viana.

In the work involved for the CSIC, Felix Viana and Victor Meseguer, CSIC researchers in Sensory Transduction Group and Nociception Neuroscience Institute of Alicante (a joint CSIC and University Miguel Hernandez).

The first author of the work, Karel Talavera, belongs to the laboratory for the study of ion channels (Catholic University of Leuven) and is currently undertaking a stay as guest researcher at the working group of researchers from the CSIC.

This is the conclusion of the team of Dr. Jennifer O’Loughlin, who published the results of their study in American Journal of Epidemiology.

O’Loughlin, of the University of Montreal, Quebec, suggests that efforts to prevent smoking should take into account “the individual factors such as age, self-esteem, alcohol use and school performance.”

They should also be considered “contextual factors such as parental smoking and friends, and school smoking policies,” the expert told Reuters Health.

The team investigated how these factors modify the onset smoking in 877 students (half male) who had 13 years at baseline.

Over the next five years, the team interviewed every three months to students on the consumption of snuff and other factors potentially associated with smoking initiation. During this period, 421 (48 percent) began smoking, 87 of them (21 percent), daily.

Living in a single parent and poor school performance has increased the risk of starting to smoke. Drinking alcohol tripled the risk.

Having brothers and friends who smoke increased two to three times the risk of teens smoking. If the parent, teachers and school staff smoked, the risk of starting smoking was multiplied by 50 percent or more.

Feeling the urge to smoke a cigarette rose six times the risk. Adolescents who felt stressed, acting impulsively and were susceptible to snuff advertising were also more likely to start smoking.

In contrast, gender, parental education, the feeling of depression, concerns about weight or overweight, the pursuit of new sensations, exercise and sports, and watching TV were among the factors that were not associated with increased risk of starting to smoke.

Prevention programs and smoking cessation-oriented social snuff consumption in the home and school, as well as advertising on snuff would have a positive effect on adolescent cigarette smoking, summarizes O’Loughlin.

The authors suggest that more research is needed on factors associated with alcohol consumption and smoking, and genetic variables associated with the risk of starting to smoke.

The British researchers surveyed middle-aged women with breast cancer in the clinics, about their health habits and followed up for seven years.

A quarter of women reported no alcohol use and most of the remainder reported that the average consumption was one drink per day.

The researchers compared to light drinkers of two or fewer drinks a week, with people who drank more.

Each extra drink per day increased the risk of breast cancer, rectum and liver, from the University of Oxford, researchers report in the Journal of the National Cancer Institute.

The type of alcoholic beverages such as, wine, beer or spirits did not matter, defined earlier research that alcohol consumption was associated with esophageal and oral cancer, only when the drinkers were smokers.

Furthermore, moderate drinkers actually had a lower risk of thyroid cancer, Hodgkin lymphoma and renal cell cancer.

For a woman the risk is manifested by a small total alcohol in developed countries, about 118 of every 1,000 women develop any of these types of cancer and every extra daily drink added 11 breast cancers, plus four other types.

But in the whole population, 13 percent of cancer cases in Britain may be attributable to alcohol, this being the conclusion of the study.

As symptoms of the disease may be mentioned the intense abdominal pain that occurs in the pit of the stomach, with nausea and vomiting, the patient having an attack of severe constipation.

In 80% of cases the disease has a benign course and the person ceases to have discomfort in a period of 3 to 7 days, the rest is an evolution that leads to disease state of “serious” if it takes the form early intensive treatment.

Other causes that can lead to suffering from pancreatitis is the fact that a person suffers a car accident and the seat belt injury blow produces a level of pancreatic tissue, which brings with inflammation.

Also suffer some type of infection can cause inflammation of the parotid gland, which is the largest of the salivary glands and can lead to acute pancreatitis.

There is currently no medication to resolve the inflammation of pancreatic tissue, therefore, if the cause is alcohol a person should avoid it and especially at a young age, as the band of people between 20 and 50 years is the most affected by this disease.

A mouse study conducted by the team of Ian Maze, of Mount Sinai School of Medicine in New York, found that chronic cocaine addiction prevented a specific enzyme to carry out its work of elimination of some genes in the brain’s pleasure circuits.

This effect was eager than rodents more drugs.

The research helps explain how cocaine use changes the brain, said Dr. Nora Volkow, director of the National Institute on Drug Abuse, part of the National Institutes of Health, which funded the study published in the journal Science.

“This discovery is enabling a new understanding of how the repeated use of drugs in the long term modifies the function of neurons,” Volkow said in a telephone interview.

For the study, the researchers administered to a group of young mice repeated doses of cocaine and other, repeated doses of saline and then single cocaine.

The authors found that one way that cocaine alters the brain’s reward circuitry is through repression 9A gene, which produces an enzyme that plays a key role in gene activation and deactivation.

Other studies have found that animals exposed to cocaine for a period of time are subject to drastic changes in how genes are turned on and off, and develop a strong preference for cocaine.

This work helps explain how this happens, Volkow said, and even lead to new ways of overcoming addiction.

In the study, Maze and his colleagues showed that these effects could be reversed by increasing the activity of the gene 9A.

“When that is done, completely reversed the effects of chronic use of cocaine,” he added.

Maze noted that this mechanism will not only reduce dependence on cocaine and could lead to a new area of research in addictions to other drugs, alcohol and even nicotine.

After reviewing existing research, Finnish experts concluded that smoking is “modestly” associated with the risk of pain in the lumbar spine and the effects would be “at least partly reversible.”

These findings were published in the January issue of American Journal of Medicine.

Dr. Rahman Shiri, the Finnish Institute of Occupational Health, and colleagues wanted to know if smoking increases the risk of low back pain, a problem that affects about 8 out of 10 adults at some point in their lives.

Previous analysis of existing studies has reached different conclusions. While research suggests a relationship between smoking and back pain, another cast “unclear results.”

Finnish researchers identified and reviewed 81 studies conducted worldwide between 1966 and 2009, which included smokers, former smokers and people who had never smoked. They took account of back pain.

Of the total, 40 studies involving over 300,000 adults and adolescents met the standards for analysis.

The Finnish team found that even if the data do not prove that smoking leads to back pain, analysis of previous literature suggesting an association “modest” between smoking and pain in the lower back.

“Current smokers (adolescents and adults) are 31 percent greater risk of low back pain compared with those who never smoked, but this increase is only for low back pain for a day or more in the last 12 months,” said Shiri.

The association between smoking and back pain was stronger when considering the “chronic or disabling low back pain, but Shiri said that none of the studies was designed to determine if there was a causal link.

Scientists do not know why smoking would be associated with low back pain but there are some possible explanations, including a reduction of blood flow in the bone, increased risk of osteoporosis and the increased movement of chemical pain drivers the blood of smokers.

Research suggests that young people “would be more vulnerable than adults to the effects of smoking” because the cigarette-related low back pain was higher among adolescents than in adult smokers.

Another explanation, they said, would be easier to identify and study the real rate of low back pain in young people than adults.

The study also suggests that “the effects of smoking would be at least partly reversible, since former smokers were less likely to seek care for low back pain than current smokers.

However, the authors concluded more research is needed on the ex-smokers to reach a more definitive answer.

Treatment with nicotine patches that are left in patients six months, and not the two recommendations would be much more effective in helping you quit smoking, according to new research published yesterday in the journal Annals of Internal Medicine.

The study was conducted by the School of Medicine, University of Pennsylvania. Caryn Lerman, the author remarked that these new findings should serve to modify and give a new spin on smoking cessation treatments.

The research involved 568 people who used the nicotine patch Nicoderm Code and after six months, patches inactive.

After this process, patients who received continuous treatment were twice as likely to quit as those who receive the patch inactive after eight weeks.

“We found that extending the duration of therapy to 24 weeks was significantly more effective in helping smokers quit, compared with standard duration of eight weeks,” said Lerman, according to published news agency Prensa Latina.

However, after a year left to differentiate the most important measurements of those who had made the long-term treatment and smoking and those who do not. That’s why scientists continue to experiences to determine if there is a exact time to be completed treatment with patches to quit snuff, or be combined therapies.

The fundamental characteristics of drug addiction treatment, consist of a series of consultations and medical interventions for the patient. In these sessions, medical, which can be given in different ways, seeks to support the addict in order to rehabilitate.

They are different techniques and forms of rehabilitation, adapting to the emergency department patient dependency, the risk of it and the properties of substances consumed. In turn, there are also differences according to the forms that can be used, according to the characteristics of each individual. There are treatments that, in most cases are characterized by individual.

The most important in a rehabilitation process is awareness on the part of the addict’s problem we have. If this step is taken, it is very important to the containment and support that family and friends can give. Well, the next step is the instance where you must deal with withdrawal syndrome.

Different types of treatment

The most important thing about the treatment of addictions, is that it is a process where the results become apparent if you have patience and perseverance in the presence of medical meetings. There are ways in which treatment plan is designed according to the individual. However, in the case of alcoholism in particular, presents the possibility of the group sessions, such as, for example associations of Alcoholics Anonymous.

Equally, in addiction to drugs and alcohol, it presents the possibility of individual process. In general terms, treatments consist of patterns of action, beyond the forms or techniques used.
These patterns are of a psychosocial, psychological, pharmacological and self-help. After the early stages, where it passes through withdrawal from drugs or alcohol, therapies are essential to control and no patient relapsed.

The main obstacle, in which most consumers can not stop the drug, or by which many consumers culminate by becoming addicted, the withdrawal syndrome. Any addictive substance, occurs when consumption is stopped, withdrawal.

As withdrawal is known to all the symptoms and effects produced by the body accustomed to a substance, when consumption slows it. These symptoms are the leading consumers to the need to eat again, a matter of avoiding them.

The withdrawal in detoxification

The detoxification treatment for heroin or other opiates, must be accompanied by proper medical supervision. The withdrawal, in most cases, is treated with drugs that reduce symptoms. However, it is important to find the right amount of these drugs, as well as not allowing the addict to rid their medication.

The withdrawal syndrome is presented, depending on the substance, from 12 hours to 48 hours after the last dose consumed. The effects and withdrawal symptoms can last from 7 days to 2 weeks. As mentioned, this depends on the substance has been consumed, and the individual itself.

After past the time of withdrawal, therapy is very important because depression acts strongly on the individual, filling in many cases, a new consumption.
