Smoking increases risk of developing active tuberculosis

Smoking doubles your risk of catching active tuberculosis

It is well known that smoking kills you slowly, but new research has found that it can also kill you quickly, by doubling your chances of catching active tuberculosis.
Tuberculosis is an infection caused by a germ, spread through the air, that usually affects the lungs. About one in ten of those infected with the germ gets active tuberculosis. If left untreated, active tuberculosis kills more than half of those infected.
A new study on the incidence of tuberculosis in Taiwan compared the likelihood of developing active tuberculosis among former and current smokers and non-smokers. It found that those who had smoked in the past had 2.69 times the risk of developing active tuberculosis compared to those that had never smoked, while current smokers had 2.73 times the risk.
"In this prospective cohort study we found a two-fold increase in the risk of active TB in current smokers compared with never-smokers," said the lead author, Hsien-Ho Lin, research fellow at Brigham and Women's Hospital in Boston.
The study also found that younger smokers were more likely than smokers older than 65 to develop active tuberculosis when compared to those who had never smoked.
"To our knowledge this is the first cohort study from a general population that provides evidence on the positive association between tobacco smoking and active TB. Based on results from ours and other studies, policy makers and public health personnel should consider addressing tobacco cessation as part of tuberculosis control. From the perspective of prevention, the target of smoking cessation should aim beyond TB patients to reach high-risk populations who are most likely to benefit from cessation," said Dr. Lin.
The results are reported in the September 1st issue of the American Journal of Respiratory and Critical Care Medicine.

Why you should never ignore a 'smoker's cough'

Why you should never ignore a  smoker s cough

You shrug off that morning throat-clearing session as a “smoker’s cough”, vowing to go easy on the tobacco next time you’re out with your mates.
But you may be ignoring that persistent hacking at your peril.
The fact is there is no such thing as a smoker’s cough and what you dismiss as a by-product of a big night out could be the first warning sign of one of the UK’s biggest killers.
Chronic Obstructive Pulmonary Disease (COPD) affects the lives of as many as 3.7 million people in the UK and kills around 30,000 a year – that’s more than those that die from breast, bowel or prostate cancer.
Typically, the disease affects people over 35 who are, or have been, heavy smokers. But it can afflict social smokers or even those exposed to passive smoking.
It also affects those who work with certain chemicals or coal dust, while recent research suggests certain genes may be to blame.
So what is COPD? It is, in fact, an umbrella term for a number of conditions, including chronic bronchitis and emphysema. It leads to damaged airways, which make it harder for air to get in and out of the lungs.
The early signs can be a so-called “productive” cough, with phlegm. But this can later develop into more persistent coughing, as well as wheezing, breathlessness and chest infections.
The severity of symptoms can vary from coughs and breathlessness during the winter months or after a cold, to experiencing shortness of breath every day.
Dr Nicholas Hopkinson, COPD specialist at the Royal Brompton Hospital, explains: “The lungs become damaged and inflamed, which causes a steady decline. The problem is that most people don’t realise they have the disease until they’ve been admitted to hospital, by which time they’ve probably had around 20 years of lung damage.
“People often put their breathlessness and chest infections down to age so don’t bother seeing their GP but, in fact, there’s nothing normal about being out of breath.”
To mark World COPD Day (November 16) health professionals are now calling on people with some of the more common symptoms to ask their GPs for a simple health test that could help save their lives.
A spirometry check assesses how well your lungs work: by blowing into a machine called a spirometer the volume of air you breathe out is measured, establishing whether your airways are obstructed – a key symptom of COPD.
The test can tell how severe the disease is and how it might develop, allowing you vital time to address the problem and make changes to the way you live.
The British Lung Foundation website www.lunguk.org even has a quick online questionnaire that can help you decide whether you need to see a doctor – asking, for instance, ‘When do you feel breathless?’ and ‘Do you often get winter bronchitis?’
According to the charity: “Early diagnosis is key as it allows patients to take steps to slow down the progression of the disease, and live healthy lives for longer. However, not enough patients are diagnosed early enough.
“There are an estimated 3.7 million people in the UK with COPD, yet only 900,000 people diagnosed with the disease. This leaves approximately 2.8 million people that are unaware they have the disease which, if left untreated, could severely restrict their lives and eventually kill them.”
But is there anything you can do to stave off COPD – or help stop it in its tracks if you already have it?
The first thing is, of course, to stop smoking. Although this won't reverse any damage to the airways which might have occurred, it can prevent the disease from getting worse, if caught early on.
After that, it is important to stay active and fit even if you have been diagnosed, as well as maintain a healthy body weight and eat a balanced diet.
As the British Lung Foundation says: “People with COPD may reduce their activities to avoid becoming breathless. But by reducing activity levels you become less fit and therefore get breathless even sooner when you try to do any activity.”
For chronic sufferers, there are inhalers that can help with breathlessness as well as antibiotics, oxygen therapy or steroids, prescribed by a doctor. And having a flu vaccine every year can also help, because flu can exacerbate COPD symptoms.
Many hospitals offer pulmonary rehabilitation courses, including gentle exercise and advice, for those whose quality of life is affected.
But the key thing to remember is that there are treatments for COPD – and the earlier you get help the better.

10 Tanaman Ajaib Penurun Kadar Gula Darah

http://rumahdiabetes.com/10-tanaman-ajaib-penurun-kadar-gula-darah/


Anda penderita Diabetes? Jika kadar gula darah Anda bermasalah, tak ada salahnya mencoba 10 bahan berikut yang membantu menurunkan gula darah, meningkatkan sensitifitas insulin, menurunkan tekanan darah tinggi dan kolesterol, dan beberapa manfaat lain.

1. Gymnema Sylvestre
Fungsi utama: Menurunkan gula darah
Dosis umum: 200 – 250 miligram per hari

Gymnema SylvestreNama Hindi tumbuhan ini berarti ‘penghancur gula’, dan tanaman ini dikatakan memiliki kemampuan untuk menurunkan kemampuan mendeteksi rasa manis. Tanaman ini dianggap sebagai tanaman paling kuat untuk mengendalikan gula darah. Kemungkinan besar, cara kerjanya adalah dengan meningkatkan aktivitas enzim yang membantu sel tubuh untuk menggunakan glukosa atau dengan merangsang produksi insulin. Walaupun belum ada penelitian intensif, tapi belum ditemukan adanya efek samping serius untuk penggunaan tanaman ini.

2. Pare
Fungsi utama: Menurunkan gula darah
Dosis umum: 50 – 100 mililiter (3-6 sdm) jus per hari


Pare yang pahit ini dianggap mampu membantu sel menggunakan glukosa secara lebih efektif dan meredam penyerapan gula di dalam usus. Para peneliti di Filipina yang meneliti konsumsi pare kepada pria dan wanita dalam bentuk kapsul selama 3 bulan menemukan adanya penurunan gula darah, walaupun sedikit, tetapi konstan. Permasalahan yang muncul adalah masalah pencernaan, tapi tidak jelas apa.

3. Magnesium
Fungsi utama: Menurunkan gula darah
Dosis umum: 250 – 350 miligram per hari


Kekurangan magnesium tidak jarang ditemui sebagai salah satu penyebab diabetes, bahkan gejala ini memperburuk kondisi gula darah dan resistansi insulin. Beberapa penelitian menunjukkan bahwa suplemen magnesium dapat memperbaiki fungsi insulin dan menurunkan gula darah. Coba konsultasikan dengan dokter Anda sebelum mengkonsumsi insulin.


4. Prickly Pear Cactus (Daging buah kaktus)

Fungsi utama: Menurunkan gula darah
Dosis umum: jika dikonsumsi sebagai makanan, 150 gram rebusan kaktus per hari.


Buah matang dari kaktus ini mampu menurunkan kadar gula darah dalam tubuh. Bentuk yang bisa ditemui adalah dalam bentuk buah, atau jus, atau bubuk. Para peneliti menemukan bahwa buah ini menurunkan kadar gula darah karena adanya komponen yang mirip dengan insulin. Buah ini juga tinggi kadar seratnya.

5. Gamma-Linolenic Acid (Asam Linoleat Gamma)
Fungsi utama: Mengurangi sakit saraf
Dosis umum: 270 – 540 milligrams sekali per hari


Asam Linoleat Gamma, atau GLA adalah asam lemak yang ditemukan dalam minyak bunga evening primrose. Beberapa penelitian menunjukkan bahwa penderita diabetes adalah orang yang memiliki level GLA rendah dalam darah, dan penelitian menunjukkan bahwa suplemen ini dapat menurunkan, bahkan mencegah sakit di saraf yang muncul akibat diabetes

6. Chromium (Krom)
Fungsi utama: Menurunkan kadar gula
Dosis umum: 200 mikrogram per hari.
Mineral ini dianggap mampu meningkatkan kinerja insulin dan terlibat juga dalam metabolisme karbohidrat, lemak dan protein. Beberapa penelituan menunjukkan bahwa mineral ini membantu menurunkan gula darah, tapi hanya untuk mereka yang memang kekurangan krom.

7. Bilberry
Fungsi utama: Melindungi mata dan syaraf

Dosis umum: 80-120 miligram standar billberry extract per hari.
Saudara blueberry ini memiliki antioksidan kuat dalam buah dan daunnya. Antioksidan yang dinamai antosianidin ini, membantu mencegah kerusakan sel darah kecil yang dapat merusak saraf dan retina mata. Penelitian terhadap hewan menunjukkan adanya penurunan gula darah juga akibat konsumsi buah

8. Alpha-Lipoic Acid (Asam Alpha Lopoic)
Fungsi utama: Mengurangi rasa sakit syaraf, dan menurunkan kadar gula darah
Dosis umum: 600-800 miligram per hari.
Disingkat ALA, bahan yang mirip vitamin ini menetralkan berbagai radikal bebas. Pembentukan radikal bebas adalah salah satu faktor peningkatan gula darah, dapat membuat kerusakan saraf dan berbagai masalah lain. ALA jg mampu membantu sel otot untuk menyerap gula darah. Di salah satu penelitian di Jerman, sekelompok peneliti memerika 40 orang dewasa yang mengkonsumsi ALA dan placebo. Di akhir studi selama 4 minggu, ditemukan bahwa ALA meningkatkan sensitifitas insulin sebanyak 27 persen.

9. Fenugreek
Fungsi utama: Menurunkan gula darah
Dosis umum: 5 sampai 30 gram setuap makan, atau 15 sampai 90 gr per hari.


Biji-bijian yang digunakan sebagai bumbu masakan India ini mampu menurunkan tekanan darah, meningkatkan sensitifitas insulin, dan menurunkan kolesterol, menurut beberapa penelitian. Efek ini mungkin timbul karena tingginya kadar serat. Bijinya jg mengandung asam amino yang meningkatkan produksi insulin. Di salah satu penelitian terhadap fenugreek, 60 orang yang mengkonsumsi 25 gr bumbu ini menunjukkan peningkatan yang baik terhadap pengendalian gula darah.

10. Ginseng
Fungsi utama: Menurunkan gula darah
Dosis umum: 1-3 gram per hari dalam bentuk kapsul atau tablet, 3-5 mililiter dalam bentuk tincture 3kali sehari.


Dikenal karena kemampuannya yang mendorong sistem kekebalan tubuh, ginseng ini memiliki beberapa hasil positif mengenai diabetes. Para peneliti menemukan bahwa ginseng memperlambat penyerapan karbohidrat, meningkatkan kemampuan sel dalam menyerap glukosa, dan meningkatkan pelepasan insulin dari pankreas. Ditemukan juga di Toronto dalam suatu penelitian, bahwa ginseng mampu menurunkan kadar gula sampai 15-20 persen.

Tak ada salahnya Anda mencoba suplemen alami tersebut, tapi ada baiknya konsultasikan dengan dokter Anda sebelum mengonsumsinya. Jika tidak ada perubahan setelah satu atau dua bulan, hentikan dan jangan buang-bunga lagi uang Anda. Salam sehat! (kpl/wiedy/rit)
