Smoking cessation offers measurable benefits for asthmatic patients

The Medical News


Asthmatic smokers may be able to reverse some of the damage to their lungs that exacerbates asthmatic symptoms just by putting down their cigarettes, according to research out of the University of Groningen in the Netherlands.
The research is published in the December 15 issue of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

"We found that exposure to cigarette smoke appears to increase the thickness of the epithelium, or lining, of the airways in the lung. This may be the underlying cause of the fact that smoking asthma patients experience more asthma symptoms, such as shortness of breath and phlegm production, compared to non-smoking asthma patients," said Martine Broekema, Ph.D., the lead author of the study.

Dr. Broekema and colleagues examined patients with asthma who were assessed each for the severity of their asthma and allergy, given questionnaires to determine the extent of their smoke-induced symptoms, and then underwent bronchial biopsies. Of the total of 147 patients, 66 never smoked, 46 were ex-smokers and 35 were current smokers.In addition to the changes in the epithelial thickness, Dr. Broekema found distinct differences between the current smokers and the ex- and non-smokers.

"In addition to the epithelial thickening, we found that cigarette smoke negatively affects levels of exhaled nitric oxide, making it an unreliable indicator of asthma severity in smokers," she said.

Current smokers also had more mucous-producing goblet cells in their epithelium and, the epithelial cell layer contained more mucus protein overall, when compared to never-smoking asthmatics. "These pathological findings were associated with the severity of phlegm production reported by the asthma patients, suggesting a causal relationship between the two. Smoking asthmatics also showed a distinct inflammatory profile in their lungs compared to never-smoking asthmatics, with a lower number of eosinophils and higher number of mast cells," said Dr. Broekema. "Furthermore, our data suggest that smoking cessation can reverse the thickening of the lining of the airways.

"To determine the role of exposure length on asthmatic lungs, the scientists divided the ex-smokers into two groups: those with fewer than the median 3.4 pack-year exposure and those with more than 3.4 pack-years.Interestingly, while they expected to find evidence of a dose-response effect between smoking and epithelial remodeling, no such association was apparent between the number of pack-years or duration of smoking cessation and epithelial remodeling.

"To our surprise, these two sub-groups of ex-smokers showed no difference in any outcome measure. These sub-analyses indicate that the amount of smoke exposure in the past does not influence our outcome measures," said Dr. Broekema. "This study shows again how important smoking cessation is for pulmonary health, and this appears to be especially true for asthmatic patients. The good news is that quitting appears to have a measurable benefit in these individuals."

ACT bans smoking in outdoor eating areas

-ABC News

The ACT Legislative Assembly has passed tough laws banning smoking in outdoor dining and drinking areas.

Smoking is already banned in enclosed areas and the new laws will come into affect in 12 months.

Health Minister Katy Gallagher says it is a substantial step forward in reducing the harm caused by tobacco.
"In 12 months there will be no smoking in Canberra's restaurants, cafes and coffee shops," she said.

"Pubs and clubs however will be able to designate an outdoor smoking area of no more than 50 per cent of their outdoor space."

Ms Gallagher says food and drink will not be permitted in the designated smoking areas and people under the age of 18 will not be allowed in.

"This is protecting workers and members of the public from exposure to tobacco smoke," she said.

"Workers in the hospitality industry deserve the same protection that is provided to those working indoors."
The amended bill also bans smoking at all children's events.

"Not only will our children and young people no longer be exposed to the effects of tobacco smoke but the [ban] will also reinforce the no smoking message, helping to reduce the likelihood of young people taking up smoking," Ms Gallagher said.

The Opposition supported the legislation in general but health spokesman Jeremy Hanson raised some concerns.

"My concern is this will force smokers onto pavements rather than in designated smoking areas," he said.

"If that happens then that will be a negative consequence."

Newswatch Bags Four NMMA Awards

Written by Godfrey Azubike


Two Newswatch editors were among the award winners at the recent Nigeria Media Merit Awards' ceremony in Enugu
For a magazine that will be marking its 25th anniversary in two months time, Newswatch had long come to be noted for excellence and success. Winning laurels has become for it a feature of its existence and an attestation of its pre-eminent position as Nigeria’s leading newsmagazine.
On November 21, in Enugu, at an event marked to celebrate media excellence in Nigeria, Newswatch again proved its mettle by carting home four awards. The feat was accomplished by Chris Ajaero, assistant general editor, and Emmanuel Uffot, assistant editor. The duo won two awards each at the Nigeria Media Merit Awards, NMMA, held at the Nike Lake Hotel and Resort, Abakpa Nike, Enugu, that Saturday.
Ajaero won the Cecil King print journalist of the year prize as well as the Chevron Nigeria prize for Oil and Gas reporter. Uffot emerged tops in the Intercontinental Bank prize for Capital Market Reporter of the year and the Aviation Industry Reporter of the year category. They both got certificates of honour as well as cash prizes for their efforts.
Ajaero got additional laptop from Chevron, sponsors of the oil and gas award category. Taiwo Idowu of Chevron presented the gift to Ajaero. It was indeed a brilliant performance by the two Newswatch staff. The award has added to their trophy house. They both are past winners of the NMMA awards.
Ajaero first won the NMMA investigative reporter of the year in 2006, followed by the political reporter award in 2007 as well as five different DAME awards, a separate award body, while Uffot, who joined Newswatch in 2007, also clinched the Agric/Environment reporter in 2001 before later winning two DAME awards: Aviation reporter of the year 2003 and Capital Market reporter of the year 2004.
Other journalists also won laurels at the Enugu event. The roll-call began with the pronouncement of Olusola Fabiyi of Punch as winner of the Abubakar Imam prize for Newspaper Features Writer, followed by Lateef Ololade of Nationnewspapers who won the Entertainment Reporter award. Others include Lookman Ajisegiri of TELL, the news photographer of the year; Salif Atojoko of Broad Street Journal, the Money Market reporter of the year; Chukwuma Muanya of The Guardian, the newspaper reporter of the year; Shaun Igbalode of IT and Telecom Digest, the telecommunications reporter of the year and Stella Sawyer of TELL, the Agriculture Reporter of the year and female reporter of the year.
Sina Fadare emerged tops in the Culture and Tradition category; Kunle Solaja won the sport writer of the year while Chikodi Okereocha of Broad Street Journalwas voted the Education reporter and Industry reporter of the year, respectively. Like Ajaero, Okereocha also got a brand new laptop from British American Tobacco, sponsors of the industry category as well as a camera from MTN, for emerging the runners-up in the telecommunications category. In all, Broad Street Journal won eight awards while TELL got five.
TELL also won the newsmagazine of the year award while The Guardian, Channels TV and 93.7 Rhythm were adjudged the newspaper of the year, the Television Station of the year and Radio Station of the year, in that order.
Deji Badmus of Channels won the Cadbury Prize for TV reporter of the year; Ogundimu Olayinka of Silverbird carted home the Television Production of the Year prize; Seun Olagunju of AIT was voted the newscaster of the year while Momoh Kubanje of Radio Continental beat other contestants to clinch the Radio presenter of the Year Prize. Unfortunately, Kubanje, a star presenter, was not around to savour his moment of glory. He died few weeks to the NMMA event. A minute’s silence was held in his honour.
Apart from Newswatch’s four awards, the magazine was also nominated in two other categories. Sebastine Obasi, the magazine’s senior staff writer, and Anthony Akaeze, principal staff writer, were among the three nominees in the banking and finance and sport categories that were won by Solaja of Soccer Star and Raymond Mordi of Broad Street Journal.
Alade Odunewu, board chairman of NMMA, in his speech, said the NMMA awards were instituted to promote media excellence and foster unity in the country. He challanged journalists not to shirk their responsibility of holding government accountable to the people.
Tony Momoh, former information minister, who was the chairman of the NMMA award nominating panel, informed the audience that the panel that vetted the entries was inaugurated on May 12, and submitted its final report on July 14. The evaluation covered works published in 2008. Momoh enjoined journalists to always strive to improve on their performance to attain excellence.
The NMMA award night was the culmination of a three-day event that began a day earlier when the cream of Nigerian journalists landed in the town fondly called the “Coal City.” But things didn’t quite work out as planned, as the event could not begin as scheduled. The award presentation that was billed to commence at 6:00 p.m. could not start until some minutes past 10 p.m. The long delay was due to the absence of officials of the Enugu State govenment led by Sullivan Chime, the governor. For more than four hours, the audience was kept waiting.

Nigerians smoke 93 million sticks of cigarettes yearly

-Yekeen Nurudeen

The World Health Organisation (WHO) also said that eight million people die yearly of tobacco-related diseases worldwide.

While receiving an award as the WHO Man of the Year 2009 on tobacco control, Modibbo said he was surprised when the British American Tobacco (BAT) Company told him that it produces 93 million cigarettes, which Nigerians consume yearly.

“I was so happy when I visited BAT on invitation in Ibadan and they said they produce 93 million sticks of cigarettes yearly. But when I asked them which country they export them to, they said it is consumed in Nigeria,” the former minister stated.

Presenting the award on behalf of the World Health Organisation (WHO), Dr. Olaokun Soyinka, the son of Prof. Wole Soyinka, said globally about eight million poeple die of tobacco-related diseases.

Soyinka noted that the reason the company was allowed to establish in the country had been defeated, as the organisation had not been able to employ up to 900 people so far, adding that farmers were finding it difficult to pay for the machines provided to them by the tobacco firm.He lamented that the tobacco company was driven away from its home country only to relocate to tNigeria to kill its youths.

According to him, WHO takes the issue of tobacco seriously as the organisation is doing all it can to reduce the supply and demand of the product. He, however, lamented that the company is lobbying the National Assembly to kill the bill banning smoking in the country.

Africa still threatened by tobacco, cancer epidemic

By Olayinka Oyegbile

Despite recent enactment of laws to ban smoking in public places in some countries across the African continent, a new report ‘Global Voices: Rebutting the Tobacco Industry, Winning Smoke free Air’ has raised alarm that 90 percent of Africans are exposed to second hand smoke; a situation in which a non-smoker is made to inhale tobacco smoke thus contracting cancer.
According to the report, which was released at a Media Summit at the seventh African Organisation for Research and Training in Cancer, AORTIC, in Dar es Salaam, Tanzania, efforts to curb smoking on the continent are being threatened by “the tobacco industry’s aggressive efforts to stop public health interventions.”
It added that the tobacco industry is using several tactics to hold back legislation and convince African governments that tobacco was important to economic activity.
The report added that the industry was opposed to increase of taxes on cigarettes and implementation of smoke free laws by arguing that it will result in loss of revenues for government and job losses for the populace.
Opposition by tobacco industry
However, the report argued that increase of taxes on cigarettes would lead to decrease in the consumption of the commodity on the continent by about 60 percent. It said this has been proved in South Africa where its consumption has fallen by one-third since taxes were raised in 1993. It estimated that, by 2010, smoking will kill about six million people worldwide. Out of this, 72 percent would be from low and middle income countries, which are in Africa and Asia.
Speaking at the launch, Otis Brawley, the chief medical officer of the American Cancer Society, said “For the first time in history, we have the tools in hand to prevent a pandemic. Recent date suggests that, with current trends, more than half the region of Africa will double its tobacco consumption within 12 years. Smoke free public places are one example a low-cost and extremely effective intervention that must be implemented to protect health.”
The report acknowledged that, although smoke free laws have been passed by some countries, implementation is a big challenge while ignorance of the harm caused by second hand smoke is widespread. According to it, in Abuja “Fifty five percent of school students are not aware that second hand smoke is harmful to health, and only one percent of Nigeria’s population is protected by strong smoke free laws.”

Time to nail breast cancer

By Olukorede Yishau

Betty Anyanwu-Akeredolu woke up one day and had no cause to feel anything was wrong with her. She felt great and naturally had no reason to believe anything was amiss with her health. Then, she decided to have her bath. And her world came crashing like a ceiling that caved into a severe storm. It was in 1997. As she was having her bath, her fingers touched something on her. A lump? She told herself it could not be. It was a denial she did not even believe herself. Her emotions ran riot and fear took over her entire being.
For one week, she kept it to herself. She could not share the fear that she had breast cancer with anyone. Not even her husband or family doctor. She was under terrific emotional trauma. Not even her husband’s belief that she was withdrawn could draw her out.
But an angel soon came. The angel came via the a cable show. According to her, "I tuned to cable TV and chose UK living and there was Rolanda’s show tilted "this programme can save your life." It surely did, for it was about breast cancer survivors. That programme gave me what I needed most at that point in time hope that I could be a survivor too. It was the greatest spiritual upliftment I have ever had in my entire life."
She said: "By the following week, I summoned courage and went to an Alumna (University of Nigeria), Dr. Ubah at University College Hospital, Ibadan for palpation. She at last confirmed the presence of a lump. Cold reality. Numb shock. What kind of lump? Benign or malignant? It was rather too early to conclude as biopsy was yet to be carried out. However, it is pertinent to mention that by the time of confirmation of the malignancy, I had gathered myself, shut out emotions and was ready for whatever it would take to make me free of the affliction. My emotional preparedness, I want to believe, helped a lot in dealing with the problem. Without delay, on April 29, 1997, I had surgery at the University College Hospital, Ibadan successfully performed by a most caring team of doctors led by Dr. O.O. Akute (FRCS- Fellow Royal College of Surgeons). The best part of the good news was that my cancer was at stage 1 with the axillary nodes free of cancer cells."
Thanks to Rolanda’s Show, Anyanwu-Akeredolu came out of her quietude. But there are thousands of women and men currently groaning in silence over breast cancer and other forms of cancer in different parts of Nigeria.
Many are confused and find themselves pacing up and down, with beads of perspiration forming beneath their collars. Anyanwu-Akeredolu, who after surviving her ordeal founded Breast Cancer Association of Nigeria (BRECAN), said it is not unusual for people to groan in silence.
"While in the hospital, I noted the generally high level of fear, apprehension and secrecy among breast cancer patients. Nobody wanted to talk about it. Majority of the patients, due to ignorance and poverty were at the late stages of the disease when little help could be given. The lucky ones who had successful treatment shied away from discussing their experience. They simply got treated and walked away with sealed lips. Some that I managed to engage in discussions disclosed that their husbands would never let them go public about their experience with breast cancer, apparently fearing stigmatisation," she said.
It is in order to stop the silence associated with breast cancer that the month of October has been set aside worldwide to create awareness about the disease. In Nigeria, where the pandemic is on the increase, non-governmental organisations working in the area of cancer have used the month to hold events aimed at improving the awareness about breast cancer, the need for government to provide test centers and treatment facilities. Some have also used it to promote the need for legislations, which promote healthy living.
Interestingly, the need to pass the National Tobacco Control Bill, which is before the Senate has also found a space this month. The Senate Committee on Health led by Iyabo Obasanjo-Bello has held a public hearing on it, after it passed the second reading. The passage of this bill automatically means a domestication of the World Health Organisation’s Framework Convention on Tobacco Control (FCTC), a global treaty which Nigeria has ratified and is obligated to domesticate. The FCTC prescribes measures that discourage smoking and promote healthy living.
Though the causes of breast cancer have not been conclusively found, tobacco use is associated with many forms of cancer and causes 90 percent of lung cancer. Tobacco smoke contains over fifty known carcinogens, including nitrosamines and polycyclic aromatic hydrocarbons. Tobacco is responsible for about one in three of all cancer deaths in the developed world, and about one in five worldwide.
This is why the Programme Manager of Environmental Rights Action (ERA), Akinbode Oluwafemi, said it was time the Senate passed the National Tobacco Control Bill.
Akinbode told a press conference that "nobody at the public hearing, including tobacco industry lobbyists contended the lethal consequences of smoking."
He said: "Tobacco currently kills over 5.4 million people annually, over 70 per cent of those deaths occur in developing countries. Also, nobody at the public hearing (again including the tobacco companies) objected to the passage of the bill. The tobacco companies only raised a few inconsequential and unsubstantiated objections to a few provisions. Those objections were roundly defended through our presentations.
"In addition, the Public Hearing was the biggest opportunity to unpack some of the lies being peddled in the media about possible negative consequences of the bill. The bill as appropriately titled is to control tobacco consumption so as to reduce the deaths, ill-health, social, economic and environmental costs associated with tobacco use. The bill has no provision about outlawing or forcefully closing down tobacco factories as being circulated in a section of the media. At the public hearing, the tobacco industry and their agents finally put paid to their widely peddled fairy tale of massive job losses if the nation implement effectives tobacco control laws."
He further explained that "In fact, the British American Tobacco Company Nigeria, the company which controls over 82 per cent of the Nigerian cigarette market, in its presentation at the public hearing, allayed all fears of massive job losses when it disclosed in the presence of distinguished Senators that it has 850 staff. To further debunk the massive job loss propaganda, the Association of Tobacco Wholesalers and Association of Tobacco Retailers put their combined staff strength at about 4,000. Thanks to the public hearing and the Senate Committee on Health, Nigerians now know for a fact that the 300,000 or 500,000 job propaganda is huge lie."
He said the only way forward is that "Senator Obasanjo-Bello and members of the committee should fire at full speed to present the Bill before the Senate plenary. We urge the Senate to complement the success recorded by the Health Committee and the example shown by the Osun State House of Assembly by fast tracking the National Tobacco Control Bill. Nigerians are dying by the seconds due to tobacco addiction while tobacco manufacturers smile to the banks. Every delay is more deaths, more ill-health. Nigerians and indeed the entire world are watching. We are waiting."
While the waiting game continues, experts have pointed out that though women may be more affected, but breast cancer is not exclusive to women. In fact, experts say it kills men faster because they are flat-chested. Statistics from the Nigerian Institute of Medical Research (NIMR) shows that men account for 20 percent of cancer cases in the country. This means one in every hundred men, as against two in every hundred women, are affected by breast cancer.
The statistics are generally glooming. Of all cancer cases that have been recorded in Nigeria, breast cancer is the leading killer, with over 30,000 cases recorded annually. Globally, not less than 400,000 women are lost to breast cancer annually.
No wonder the Executive Director of International Union Against Cancer, Isabel Mortara, said "each year, the number of women diagnosed with breast cancer and dying from it rises and the gap in survival rates between developed and developing countries widens."
It is for this reason that Anyanwu-Akeredolu said: "Cancer in general is a word that strikes fear into the heart of everyone. It is a sure killer if allowed to take control."
Another breast cancer survivor and promoter of Bloom Cancer Care and Support Centre, Dr. Kofoworola Orija, said "our personal experience of breast cancer is indeed a social issue. Every woman battles through her disease so as to bounce back in life striving to be part once more of an inclusive society."
For breast cancer patient, there are stages of cancer, which basically indicate how far cancer cells have spread within the breast to nearby tissue and other organs. Carcinoma in situ refers to the condition when cancer is static in the ducts and has not spread to other organs of the body. It has two types known as Lobular Carcinoma in Situ and Ductal Carcinoma.
Stage 0 is that stage when the cancer cells are still within the duct. By the time it gets to stages 1 and 2, the cancer has invaded nearby tissue. At stage one, the cancer is two centimetres and once it has gone beyond two centimetres, it has entered the second stage and might have spread to the lymph nodes under the armpit. At these two stages, it is not yet critical.
The critical stages begin from stage three when the cancer has grown beyond five centimetres and have spread to the lymph nodes. It is also possible that it would have spread to the chest wall, inside the chest and the skin.
As for stage four, the cancer has invaded the lungs and the bones, aside spreading to the lymph nodes. Both stages three and four are critical.
As a way of catching the lump early and killing it, the American Cancer Society (ACS) recommends annual mammogram from age 40. Mammogram is a test carried out to detect lump. ACS also recommended clinical breast examination every three years for women in their 20s and 30s and older. Also, it advises women to know how their breasts normally feel and report any change to healthcare providers. "Women at risk should talk with their doctors regularly about the benefits and limitations of starting mammography earlier, having additional tests or having more frequent exams," the ACS recommends.
It also prescribes breast self-examination (BSE) for women starting from their 20s.
BSE, says Ebunola Anozie, who is the co-ordinator of Care Organisation Public Enlightenment, is the primary weapon through which cancer can be detected early.
