Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation that is usually progressive. It includes chronic bronchitis and emphysema. COPD is diagnosed based on spirometry showing airflow limitation. Symptoms include breathlessness, cough, and wheezing. Management involves reducing risk factors, managing stable COPD with bronchodilators and rehabilitation, and treating exacerbations with bronchodilators and glucocorticoids. The severity of COPD is classified based on lung function, and treatment is escalated based on severity from short-acting bronchodilators to long-term oxygen for very severe COPD.

Asthma vs COPD - A quick summary of the differences between themLGM Pharma
Asthma is a lung disease that affects almost 20 million Americans. COPD, or chronic obstructive pulmonary disease is a chronic lung disease that afflicts 24 million patients in the U.S. COPD is mainly caused by smoking or secondhand smoke, while asthma can by caused by exposure to allergens, dust and air pollutants. Innovative treatments are needed to combat both asthma and COPD, and LGM Pharma provides quality API's for the R&D needs of clients seeking treatments for these lung diseases.
Pneumonia is an inflammatory condition of the lung affecting primarily the small air sacs known as alveoli. Typically symptoms include some combination of productive or dry cough, chest pain, fever, and trouble breathing. Severity is variable.
Pneumonia is usually caused by infection with viruses or bacteria and less commonly by other microorganisms, certain medications and conditions such as autoimmune diseases. Risk factors include cystic fibrosis, chronic obstructive pulmonary disease (COPD), asthma, diabetes, heart failure, a history of smoking, a poor ability to cough such as following a stroke, and a weak immune system. Diagnosis is often based on the symptoms and physical examination. Chest X-ray, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired with community, hospital, or health care associated pneumonia.
Vaccines to prevent certain types of pneumonia are available. Other methods of prevention include handwashing and not smoking. Treatment depends on the underlying cause. Pneumonia believed to be due to bacteria is treated with antibiotics. If the pneumonia is severe, the affected person is generally hospitalized. Oxygen therapy may be used if oxygen levels are low.
Pneumonia affects approximately 450 million people globally (7% of the population) and results in about four million deaths per year. Pneumonia was regarded by William Osler in the 19th century as "the captain of the men of death". With the introduction of antibiotics and vaccines in the 20th century, survival improved. Nevertheless, in developing countries, and among the very old, the very young, and the chronically ill, pneumonia remains a leading cause of death. Pneumonia often shortens suffering among those already close to death and has thus been called "the old man's friend"

Goal- Promote bronchodilationn Reduce inflammation Remove secretions Prevent ongoing symptoms Prevent asthma attack Maintain normal lung function Avoid triggers
Pharmacological therapy 1. Long term control medication- Inhaled corticosteroid Leukotriene modifiers Long acting beta agonist Methylxanthines Combine inhaler
2 Quick relief medication Short acting beta agonist Anticholinergic Oral or I/V corticosteroid
3 Bronchial thermoplasty- Form severe asthma that does not respond to medication
Non- pharmacological
Oxygen therapy Postural drainage & chest physiotherapy Coughing & deep breathing exercise Avoidance of allergen relaxation technique acupuncture
Prevention
Patients with recurrent asthma should undergo tests to identify the substances that precipitate the symptoms. Possible causes are dust, dust mites, roaches, certain types of cloth, pets, horses, detergents, soaps, certain foods, molds, and pol- lens. If the attacks are seasonal, pollens can be strongly sus- pected. Patients are instructed to avoid the causative agents whenever possible.
Complications Complications of asthma may include status asthmaticus, respiratory failure, pneumonia, and atelectasis. Airway obstruction, particularly during acute asthmatic episodes, often results in hypoxemia, requiring the administration of oxygen and the monitoring of pulse oximetry and arterial blood gases. Fluids are administered, because people with asthma are frequently dehydrated from diaphoresis and in- sensible fluid loss with hyperventilation.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
2. COPD, a common preventable and treatable disease, is
characterized by persistent airflow limitation that is usually
progressive and associated with an enhanced chronic
inflammatory response in the airways and the lung to noxious
particles or gases.
4. Chronic bronchitis
Defined as a chronic productive cough for three
months in each of two successive years in a
patient in whom other causes of chronic cough
have been excluded.
5. Emphysema
• Abnormal and permanent enlargement of the
airspaces distal to the terminal bronchioles
that is accompanied by destruction of the
airspace walls, without obvious fibrosis.
7. Airways
Chronic inflammation
Increased numbers of goblet cells
Mucus gland hyperplasia
Fibrosis
Narrowing and reduction in the number of small airways
Airway collapse due to the loss of tethering caused by alveolar
wall destruction in emphysema
8.
9. Lung Parenchyma
• Emphysema affects the structures distal to the terminal
bronchiole, consisting of the respiratory bronchiole, alveolar
ducts, alveolar sacs, and alveoli, known collectively as the
acinus.
11. Subtype of emphysema.
Centrilobular emphysema (Proximal acinar)
• Abnormal dilation or destruction of the respiratory
bronchiole, the central portion of the acinus. It is commonly
associated with cigarette smoking,
12. Panacinar emphysema
• Refers to enlargement or destruction of all parts of the acinus.
• Seen in alpha-1 antitrypsin deficiency and in smokers
15. Pulmonary vasculature
• Intimal hyperplasia and smooth muscle hypertrophy or
hyperplasia thought to be due to chronic hypoxic
vasoconstriction of the small pulmonary arteries
• Destruction of alveoli due to emphysema can lead to loss of
the associated areas of the pulmonary capillary bed and
pruning of the distal vasculature
16. Risk Factors for COPD
• Genes
• Exposure to particles
• Tobacco smoke
• Occupational dusts, organic
and inorganic
• Indoor air pollution from
heating and cooking with
biomass in poorly ventilated
dwellings
• Outdoor air pollution
• Lung growth and
development
• Oxidative stress
• Gender
• Age
• Respiratory infections
• Socioeconomic status
• Nutrition
17. SYMPTOMS
BREATHLESSNESS:
• First symptom that bring patient to hospital.
• FEV1 declined by 1-1.5L when patient presents to hospital.
• Often assosciated with cough and expectoration.
• Varies in severity as mild,moderate,severe.
• Depends upon:temp.,occupation,position.
18. COUGH:
• First symptom to come but often ignored as smoker’s cough.
• a/w expectoration<60ml/day.
• More in morning hrs.
19. WHEEZE:
• Not characteristic feature but present.
• Due to turbulent airflow in large airways.
• Its presence indicates use of bronchodilator in management.
20. CHEST PAIN:
• Not characteristic feature of disease.
• May indicate underlying ischemic heart disease or GERD.
• Pleuritic chest pain d/t pneumothorax,infection,pulmonary
infarction.
21. • Other symptoms include:depression,weight loss,haemoptysis
• Haemoptysis if present then r/o bronchogenic ca.
22. PHYSICAL SIGNS
GENERAL PHYSICAL EXAMINATION:
• Tar stained fingers
• Cyanosis
• Flapping tremors
• When a COPD patient develops clubbing ,always suspect
and rule out bronchiectasis and bronchogenic carcinoma.
23. RESPIRATORY SYSTEM
INSPECTION:
Barrel-shaped chest ,
Accessory respiratory muscle participate ,
Prolonged expiration during quiet breathing.
Expiration through pursed lips
Paradoxical retraction of the lower interspaces during
inspiration (ie, hoover's sign)
Tripod Position
24. Tripod Position
• Patients with end-stage
COPD may adopt positions
that relieve dyspnea, such
as leaning forward with
arms outstretched and
weight supported on the
palms or elbows.
25. PALPATION:
Decreased fremitus vocalis
PERCUSSION :
Hyperresonant ,
Depressed diaphragm,
Decreasd hepatic and cardiac dullness.
AUSCULTATION:
Prolonged expiration,
Reduced breath sounds;
The presence of wheezing during quiet breathing
Crackle can be heard if infection exist.
27. COPD Diagnosis
SPIROMETRY:
• Spirometry is used to measure the forced vital capacity (FVC),
i.e. maximal volume of air forcibly exhaled from the point of
maximal inhalation; the volume of air exhaled during the first
second of this maneuver (FEV1), and the ratio of these two
measurements (FEV1/FVC).
• The presence of a postbronchodilator FEV1<80% of the
predicted value in combination with a FEV1/FVC <70%
confirms the presence of airflow limitation that is not fully
reversible.

32. Differential Diagnosis:
COPD and Asthma
COPD
• Onset in mid-life
• Symptoms slowly progressive
• Long smoking history
• Dyspnea during exercise
• Largely irreversible airflow
limitation
ASTHMA
• Onset early in life (often
childhood)
• Symptoms vary from day to
day
• Symptoms at night/early
morning
• Allergy, rhinitis, and/or eczema
also present
• Family history of asthma
• Largely reversible airflow
limitation
35. Four Components of COPD
Management(Accordindg to GOLD
Guidelines)
1.Assess and monitor disease
2.Reduce risk factors
3.Manage stable COPD
– Education
– Pharmacologic
– Non-pharmacologic
4.Manage exacerbations
36. Management of Stable COPD
• Reduction of exposure to
tobacco smoke
occupational dusts and chemicals
indoor and outdoor air pollutants
• Smoking cessation is the single most effective — and cost
effective — intervention in most people to reduce the risk
of developing COPD and stop its progression.
37. Management of Stable COPD
For patients with COPD, health education plays an important role
in smoking cessation , ability to cope with illness and health status.
None of the existing medications for COPD have been shown to
modify the long-term decline in lung function that is the hallmark
of this disease.
Therefore, pharmacotherapy for COPD is used to decrease
symptoms and/or complications.
38. Pharmacotherapy: Bronchodilators
• Bronchodilator medications are central to the symptomatic
management of COPD .
• The principal bronchodilator treatments are
ß2-agonists,
anticholinergics, and
methylxanthines
• Regular treatment with long-acting bronchodilators is more
effective and convenient than treatment with short-acting
bronchodilators.
42. Other Pharmacologic Treatments
Antibiotics: Only used to treat infectious exacerbations of
COPD
Antioxidant agents: No effect of n-acetylcysteine on
frequency of exacerbations, except in patients not treated
with inhaled glucocorticosteroids
Mucolytic agents, Antitussives, Vasodilators: Not
recommended in stable COPD
43. Non-Pharmacologic Treatments
Rehabilitation: All COPD patients benefit from exercise
training programs, improving with respect to both exercise
tolerance and symptoms of dyspnea and fatigue.
Oxygen Therapy: The long-term administration of oxygen
(> 15 hours per day) to patients with chronic respiratory
failure has been shown to increase survival.
44. COPD Exacerbations
An exacerbation of COPD is defined as:
An event in the natural course of the disease characterized by
a change in the patient’s baseline dyspnea, cough, and/or
sputum that is beyond normal day-to-day variations, is acute
in onset, and may warrant a change in regular medication in a
patient with underlying COPD.
45. The most common causes of an exacerbation are infection of
the tracheobronchial tree and air pollution.
But the cause of about one-third of severe exacerbations cannot
be identified.
46. Management COPD Exacerbations
Inhaled bronchodilators ( inhaled ß2-agonists with or without
anticholinergics)
oral glucocorticosteroids are effective treatments for
exacerbations of COPD.
Noninvasive mechanical ventilation in exacerbations improves
respiratory acidosis, increases pH, decreases the need for
endotracheal intubation, and reduces PaCO2, respiratory rate,
severity of breathlessness, the length of hospital stay, and
mortality.
Medications and education to help prevent future
exacerbations should be considered as part of follow-up, as
exacerbations affect the quality of life and prognosis of
patients with COPD

48. Surgery
In rare cases, surgery may benefit some people who have
COPD. Surgery usually is a last resort for people who have
severe symptoms that have not improved from taking
medicines.
Surgeries for people who have COPD that's mainly related
to emphysema include
Bullectomy
Lung volume reduction surgery
Lung Transplant
