Experimenting On Limited Number Of People Can Be Perilous As Side Effects Can Easily
Be Missed
With the arrival of two revolutionary treatment strategies, immunotherapy and personalised
medicine, cancer researchers have found new hope -and a problem that is perhaps
unprecedented in medical research.
There are too many experimental cancer drugs in too many clinical trials, and not enough
patients to test them on. The logjam is caused partly by companies hoping to rush profitable
new cancer drugs to market, and partly by the nature of these therapies, which can be
spectacu larly effective but only in select patients.
In July, an expert panel of the US Food and Drug Administration (FDA) approved a
groundbreaking new leukaemia treatment, a type of immunotherapy . Firms are scrambling to
develop other drugs based on using the immune system itself to attack cancers. Many of these
experimental candidates in trials are quite similar. Yet each drug company wants to have its
own proprietary version, seeing a potential windfall if it receives FDA approval.
As a result, there are more than 1,000 immunotherapy trials underway , and the number keeps
growing. “It's hard to imagine we can support more than 1,000 studies,“ said Dr Daniel Chen,
a vicepresident at Genentech, a bio technology company .
In a commentary in the journal `Nature', he and Ira Mellman, also a vice-president at the
company , wrote that the proliferating trials “have outstripped our progress in understanding
the basic underlying science“.

“I think there is a lot of exuberant rush to market,“ said Dr Peter Bach, director of the Center
for Health Policy and Outcomes at Memorial Sloan Kettering Cancer Center, “ And we are
squandering our most precious resource -patients.“
Take melanoma: There are more than 85,000 cases a year in the US, according to Dr Norman
Sharpless, director of the Lineberger Comprehensive Cancer Center at the University of
North Carolina. Most melanomas are cured by surgery, leaving about 10,000 patients who
have had relapses and could be candidates for an experimental treatment. But nearly all will
be treated by doctors outside of academic medical centres, who are not part of the clinical
trials network and so do not offer patients experimental treatments.
Companies therefore must compete for the few patients with relapsed melanoma who are at
centres offering clinical trials. Many end up struggling to find enough subjects to determine
wheth er a treatment actually works -and if so, for whom.
The problem is that many of the trials are uninteresting from a scientific view, said Dr Roy
Herbst, the center's chief of medical oncology . The companies sponsoring these trials are not
addressing new research questions, he said; they are trying to get proprietary drugs approved.
Trials involving limited numbers of patients can be perilous. In tiny studies, serious side
effects can be missed, said Dr Scott Ramsey , an oncologist at the Fred Hutchinson Cancer
Research Center, US.
Childcare
Childcare remains in infancy across state(The Tribune: 20170814)
A reality check at five government hospitals in major cities reveals that some basic facilities
are not available
http://www.tribuneindia.com/news/punjab/childcare-remains-in-infancy-across-
state/451833.html
The state government claims to have put an emphasis on better child and mother care, but a
survey of five major hospitals of the state presents a picture of contrast. The possibility of a
Gorakhpur-like tragedy can’t be ruled out.
If somewhere there is a lack of proper oxygen system, in others there is a shortage of nurses.
It is common to find shortage of pediatricians in all hospitals. In the name of “referring”,
parents of newborn and sick children keep shuttling from one place to another.
Patiala: No lessons learnt from past mistakes
In 2009, six infants were charred to death at Government Rajindra Hospital incubators, while
four others were critically injured in a fire that broke out due to electric short circuit at the
phototherapy unit of the hospital, but that doesn’t seem to have brought much change. Even
as a neonatal intensive care unit and a paediatrics intensive care unit has been set up in the
hospital, parents can’t rely on these in times of emergency.
Dr Jasvir Singh, head of paediatrics department, admitted that they had the equipment, but it
was not fully operational due to lack of proper oxygen system in the hospital. There is no
intensive care facility for children. Many basic things, including neonatal ventilators,
paediatrics ventilators and pulse oximeters are either missing or lying defunct in these units
following which more than 50 per cent critical cases are referred to the PGI, Chandigarh, or
private hospitals.
Amritsar: Diagnostic facility unavailable
A plethora of problems plagues Bebe Nanki Mother and Child Care Centre of Government
Medical College in the holy city. The parents of children coming to the centre have to take
them to private labs even for the basic tests.
The tests for sodium, potassium, calcium, CBC and others are not usually conducted at the
centre. Even the machine for conducting trans-bilirubin test is lying dysfunctional. Though
the hospital authorities claim otherwise, the presence of a large number of agents of private
labs at the entrance of the centre belie their claim. Besides, post-graduate students hold the
fort at the centre as no senior doctors are available after 2 pm.
Ludhiana: Inadequate staff to handle equipment
A visit to the Mother and Child Hospital on the premises of the Civil Hospital revealed that
although infrastructure and machinery are available, a shortage of staff has crippled its
functioning. Children requiring intensive care are either referred to the PGI or Rajindra
Hospital, Patiala. As per norms, a nurse should be available for every newborn baby, but in
reality, a single nurse is taking care of more than three babies at a given time. The other
major problem is the non-availability of doctors.
Jalandhar: Six specialists needed, two available
Every month around 400-700 children are born at the Jalandhar’s Civil Hospital. But it is ill-
equipped to deal with the patient load. There are just two child specialists against the
requirement of six. Most parents complain of a delayed response to their repeated calls during
emergencies. Besides, the hospital doesn’t have a single ventilator in the newborn baby care
unit. As per the staff, a subsidiary C-pipe ventilator alternative is used in time of
emergencies. Dr Vijender Singh, medical officer, said a demand regarding ventilators had
already been raised.
Bathinda: Services hit by lack of paramedics
While nurses are crucial to childcare, Bathinda’s Civil Hospital which caters to several
districts of the Malwa region struggles with inadequate staff. A query reveals that the hospital
doesn’t have enough trained nurses to take care of prematurely born and sick babies.
Untrained nursing students are thus making up for the staff shortage. The hospital has 17
nursing staff against 32 posts. At the childcare unit, out of 10 sanctioned posts, there are only
five nurses who work in three shifts. Since no ventilator is available for newborn babies,
emergency patients are referred to Government Medical College, Faridkot.

Japanese Encephalitis
Japanese Encephalitis in Gorakhpur: A deadly disease explained (The Hindu: 20170814)
http://www.thehindu.com/sci-tech/health/japanese-encephalitis-a-deadly-disease-
explained/article19486806.ece
Gorakhpur offers the only tertiary care centre for Japanese Encephalitis with 100 dedicated
beds.
What is Japanese Encephalitis?
Japanese Encephalitis (JE) is a mosquito-borne viral infection of the brain. There is, however,
a debate about the origin of the disease and whether it is enteroviruses — caused by virus
found in pigs and birds. There is no cure for JE.
Why only Gorakhpur?
While Gorakhpur has a considerable burden of disease, it is incorrect to assume that JE cases
are clustered in Gorakhpur district alone. JE epidemics are reported from many parts of India
however, it is highly endemic in Eastern Uttar Pradesh. Gorakhpur is a nodal point not
because there are more cases in the district but because the only tertiary care centre with 100
beds dedicated to JE is in Gorakhpur. So, cases from nearby districts like Kushinagar and
Deoria districts are referred to there for treatment.
Japanese Encephalitis
Why does vaccination not work?
It is a misconception that the JE vaccine will eradicate the disease in a short span of time.
While vaccination is critical, at the heart of U.P.’s crisis is lack of infrastructure, unclear data
on disease burden and lack of access to clean water and toilets. In March, the State
government launched a JE vaccination drive in 38 districts in U.P. but it was not
supplemented with access to clean water and sanitation.
The efficacy of the JE vaccine is between 85-90%. The lessons learnt from polio vaccination
drives is that people left out of each round of vaccination are the most disenfranchised, most
likely to take ill and least likely to seek medical care in time.
The Gorakhpur mystery...
Over the years, there have been cases in the area which are clinically different from one
another. JE is one kind of encephalitis which falls under a spectrum of diseases called Acute
Encephalitis Syndrome (AES). Doctors in endemic regions in U.P. have found cases with
similar symptoms but without the virus, leading to some debate over the cause of the disease.
While public health experts have found a difference in case definitions across Eastern
districts of U.P., this is something Indian scientific community is still trying to understand.
However, specific research on this has not been supported by the government so far, despite
decades of annual outbreaks. Due to lack of research, U.P. government gets their burden of
disease data from hospitals, essentially leaving out cases that do not come into public health
facilities. This results in wrong forecasts as the government budget for next year’s JE
intervention. Because of the lack of reliable data & research, UP’s policy intervention to curb
JE cases has failed for decades.
Were all those who died in BRD Hospital suffering from JE?
No. The State government is yet to release data of exactly how many of them were admitted
for JE treatment.
Telemedicine
Telemedicine: Odisha shows the way (The Hindu: 20170814)
http://www.thehindu.com/sci-tech/health/odisha-shows-the-way/article19482213.ece
The model of a telemedicine project begun in the State, that is creating jobs and widening
health access, is now going national
A telemedicine project started by an Odisha-based social entrepreneur is slowly going
national after the Central government adopted it as a model project two years ago. Started in
2009, the unique model that focusses on sustainability involves training of local youth in e-
medicine services and enables them to set up e-health centres in government-run primary
health-care centres (PHC), community health centres (CHC) and subdivisional hospitals.
These centres have created job opportunities for over 500 youth in Odisha and reached out to
over five lakh patients.
For jobs and health
“There are two main problems that ail us — unemployment and bad health. Through this
micro-entrepreneurship programme we have attempted to tackle both,” says Kedarnath
Bhagat, managing trustee of Odisha Trust of Technical Education and Training (OTTET)
under the aegis of which the telemedicine model was conceptualised. At OTTET, local youth
are trained for a month in an e-health assistance programme, after which they can apply for a
bank loan to start an e-health centre in PHCs and CHCs. “On average, the cost of starting a
telemedicine centre goes up to ₹6 lakh. A centre needs a staff of four people, including the
entrepreneur,” explains Mr. Bhagat, adding that typically a centre is equipped with a laptop
with video camera and basic diagnostic testing facilities like blood glucose meter, urine
analyser, heart rate monitor, etc. So far, 127 such centres have been opened in Odisha at the
village and district level (see picture).
“At no cost to the government, these centres help in offering basic testing facilities. Patients
suspected to have major illness get the benefit of the telecommunication facility for
consultations with senior doctors,” says Mr. Bhagat. The OTTET has tie-ups with
government hospitals as well as private hospitals such as Apollo, Global and Narayana
Hrudayalaya.
These telemedicine centres also create a database of personal health records of every patient
walking in for future reference. Mr. Bhagat says for a centre to be viable, the PHC or CHC
should have a footfall of about 50 patients a day. “The revenue comes from charges for tests
and tele-consultation fees. In case patients are covered under any health scheme for the poor,
these charges are borne by the scheme,” he says. The charges for tests and consultation are
fixed by the government; a basic consultation costs ₹100 while that with a super-specialist
costs ₹300.
Across other States
In 2015, a team of government consultants termed this project as one of the eight “best
practices globally”. The World Health Organisation too believes telemedicine to be
particularly beneficial for rural and underserved communities in developing countries.
While the OTTET plans to cover all 51,000 villages in Odisha, pilot programmes have begun
in Gujarat, Jharkhand, Bihar, Himachal Pradesh and Uttar Pradesh while four other States are
also in line. “Telemedicine offers phenomenal opportunities to doctors to reach out to
patients,” says Dr. Devi Shetty of Narayana Hrudayalaya. “It acts as a good bridge.”
Zika vaccine
More potent, safer Zika vaccine developed (The Hindu: 20170814)
http://www.thehindu.com/sci-tech/health/more-potent-safer-zika-vaccine-
developed/article19479682.ece
Scientists have developed the world’s first plant-based Zika vaccine that may be more
effective, safer and cheaper than other vaccines against the mosquito-borne virus.
Currently, there are no licensed vaccines or therapeutics available to combat Zika, researchers
said.
The vaccine developed by researchers from Arizona State University (ASU) in the U.S.
works against a part of a Zika viral protein, called DIII, that plays a key role for the virus to
infect people.
“All flaviviruses have the envelope protein on the outside part of the virus. It has three
domains,” said Qiang Chen, a scientist at ASU.
“The domain III has a unique stretch of DNA for the Zika virus, and we exploited this to
generate a robust and protective immune response that is unique for Zika,” said Chen, who
led the research published in the journal Scientific Reports.
The researchers first grew the envelope protein in bacteria, then prepared the DIII protein
domain in tobacco plants.
The team then performed immunisation experiments in mice, which induced antibody and
cellular immune responses that have been shown to confer 100% protection against multiple
Zika virus strains in mice.
The team’s protein-based vaccine uses the smallest and most unique part of the Zika virus
that can still elicit a potent and robust immune response.
“In our approach, we make what we call a pseudovirus. It is a fake virus. The pseudovirus
displays only the DIII part of the envelope protein on the surface,” said Chen.
“We did a test to make sure that the vaccine produces a potent protective immune response,
but also, that it does not produce antibodies that may be cross reactive for dengue, West Nile,
yellow fever or others,” he said.
The worldwide Zika threat first emerged in 2015, infecting millions as it swept across the
Americas.
It struck great fear in pregnant women, as babies born with severe brain birth defects quickly
overburdened hospitals and public health care systems.

Negative emotions
Embracing negative emotions could boost psychological well-being
(Medical News Today: 20170814)
http://www.medicalnewstoday.com/articles/318933.php
When feelings of sadness or disappointment take hold, most of us do our utmost to escape
them. However, according to new research, embracing these darker emotions is more likely
to benefit psychological health in the long-term.
In a study of more than 1,300 adults, researchers found that people who regularly try to resist
negative emotions may be more likely to experience symptoms of mood disorders months
later, compared with subjects who accept such emotions.
Lead study author Brett Ford, an assistant professor of psychology at the University of
Toronto in Canada, and colleagues recently reported their findings in the Journal of
Personality and Social Psychology.
Previous research has suggested that acceptance - whether it is embracing our good and bad
attributes, or accepting the way we look - is associated with better psychological well-being.
For this latest study, Prof. Ford and team sought to determine how acceptance of negative
emotions - such as sadness, disappointment, and anger - might influence psychological
health.
Embrace or avoid negative feelings?
To reach their findings, the researchers conducted three experiments, the first of which
involved 1,003 participants. All subjects completed a survey, in which they were asked to
rate how strongly they agreed with certain statements, such as "I tell myself I shouldn't be
feeling the way that I'm feeling."
The researchers found that participants who had lower agreement with such statements as
these - indicating a greater acceptance of negative feelings - showed higher levels of
psychological well-being, compared with subjects who attempted to resist negative feelings.
In the second experiment - involving 156 participants - subjects were asked to record a 3-
minute speech as part of a mock job application, which they were told would be shown to a
panel of judges. The subjects were given 2 minutes to prepare their speech, and they were
instructed to promote their relevant skills.

Once the recording was complete, each subject was asked to report how they felt about the
task.
The team found that participants who tried to avoid feeling negativity about the task were
more likely to experience distress, compared with subjects who embraced any negative
feelings.
The third study involved 222 participants. For 2 weeks, each subject was asked to keep a
journal to record any bad experiences, as well as their emotions in response to such
experiences. Participants were followed-up with a psychological assessment 6 months later.
The researchers found that subjects who reported trying to avoid negative emotions in
response to bad experiences were more likely to have symptoms of mood disorders, such as
anxiety and depression, 6 months later, compared with those who embraced their negative
emotions.
"We found that people who habitually accept their negative emotions experience fewer
negative emotions, which adds up to better psychological health," says senior study author
Iris Mauss, an associate professor of psychology at the University of California, Berkeley.
Acceptance may be key to stress coping
Overall, the team believes that when bad things happen, it may be better to let negative
emotions run their course rather than trying to avoid them.
"It turns out that how we approach our own negative emotional reactions is really important
for our overall well-being. People who accept these emotions without judging or trying to
change them are able to cope with their stress more successfully."
Prof. Brett Ford
"Maybe if you have an accepting attitude toward negative emotions, you're not giving them
as much attention," speculates Prof. Mauss. "And perhaps, if you're constantly judging your
emotions, the negativity can pile up."
The researchers now plan to investigate how an individual's upbringing influences their later
experiences of negative emotions and their acceptance of such feelings.
Leukemia
Leukemia: Mushroom protein could be used in future treatments (Medical
News Today: 20170814)
http://www.medicalnewstoday.com/articles/318910.php
A protein found in the edible mushroom known as "shaggy ink cap" might be able to kill a
type of leukemia cell, new research suggests.
Coprinus comatus, also known as "shaggy ink cap" or "lawyer's wig," is a type of edible
mushroom normally found in North America and Europe. Its habitat is usually meadows and
grasslands, but it can also sometimes be found along gravel roads or on lawns in towns and
cities.
It takes its common names from its white, shaggy appearance when mature, but also from the
fact that it starts "dissolving" into a black, inky mass once it starts to decay, or soon after
being picked.
This type of mushroom is already known for its nutritional value, as well as for its
antioxidant and antimicrobial potential. Some studies have also variously linked Coprinus
comatus elements with potential for HIV, prostate cancer, and ovarian cancer treatments.
Researchers from the University of Florida in Gainesville have now uncovered a new
potential for a Coprinus comatus protein: killing a type of leukemia T cell.
Dr. Yousong Ding, an assistant professor at the University of Florida, and his team looked at
how Y3, a protein present in Coprinus comatus, binds with the LDNF glycan, which is a
sugar molecule usually found in parasites. This activates a cell-signaling cascade that can
program a type of leukemia T cell to commit suicide, the researchers explain.
Their findings have recently been published in Proceedings of the National Academy of
Sciences.
Glycan binding protein programs cell suicide
Dr. Ding and his colleagues noted that the protein Y3 from Coprinus comatus has significant
glycan binding properties. This is important because the interactions of glycan binding
proteins (GBPs) can provide a better understanding of how systems respond to pathogens and
can facilitate the creation of new therapeutic pathways.
In the course of this study, the scientists tested the interaction between Y3 and LDNF using
model leukemia cells. They found that the enzymes triggered by this interaction were able to
cause the death of over 90 percent of the leukemia T cells.
In the researchers' view, this result suggests that the action of the Y3 GBP on this type of
leukemia cell can be productive and very efficient.
They suggest that this may have meaningful implications for T cell acute lymphoblastic
leukemia treatment. This type of blood cancer is particularly aggressive, and it is responsible
for up to 25 percent of acute lymphoblastic leukemias.
According to the National Cancer Institute, the estimated number of adult deaths owed to
acute lymphoblastic leukemia in 2017, in the United States, will be 1,440.
Potential pathways for new treatments
Dr. Ding suggests that the study has offered the scientists a new way of determining the
functions of proteins present in Coprinus comatus mushrooms, and of studying their action on
unhealthy cells.
The next step for the researchers is to examine other potential GBPs in more edible
mushrooms, as well as gain a better understanding of Y3 functions in relation to leukemia
cells.
Dr. Ding suggests that he and his colleagues might start testing the action of Coprinus
comatus Y3 proteins on diseased cells in animal models within a year.
The researchers express their hope that this, and similar studies, could reveal pathways for
new, more efficient drugs in the treatment of leukemia and other diseases.
"In addition to their dietary value, these proteins can be important to health improvement and
disease prevention," concludes Dr. Ding.
Restrictive lung disease
Restrictive lung disease: Types, causes, and treatment (Medical News
Today: 20170814)
http://www.medicalnewstoday.com/articles/318905.php
Restrictive lung diseases are chronic lung conditions that limit the ability of a person's lungs
to expand during inhalation.
Most cases of restrictive lung diseases are not curable, but they are often manageable with
medication and exercise regimes.

What are restrictive lung diseases?
Man with asthma inhaler.
Obstructive lung diseases, such as asthma, prevent normal exhalation. In contrast, restrictive
lung diseases prevent normal inhalation.
Long-term lung conditions are traditionally separated into two main categories based on how
they affect a person's breathing. These categories are either obstructive or restrictive.
A third category, called mixed lung disease, is smaller and has characteristics of both
obstructive and restrictive lung diseases.
Mixed lung disease most commonly occurs in people with chronic obstructive pulmonary
disease (COPD), who also have congestive heart failure.
In cases of obstructive lung diseases, such as asthma, bronchiectasis, COPD, and
emphysema, the lungs are unable to expel air properly during exhalation.
Restrictive lung diseases, on the other hand, mean the lungs are unable to fully expand, so
they limit the amount of oxygen taken in during inhalation. This limitation also restricts what
can be exhaled when compared to an average person.
Restrictive lung diseases cause a decreased lung capacity or volume, so a person's breathing
rate often increases to meet their oxygen demands.
Most restrictive lung diseases are progressive, meaning they worsen over time.
One study estimated that, from 2007 to 2010, 6.5 percent of Americans aged 20 to 79 had
restrictive lung disease.
Types
Restrictive lung diseases are often divided into two groups, depending on whether their cause
is intrinsic or extrinsic.
Intrinsic restrictive lung disorders cause an internal abnormality, usually leading to the
stiffening, inflammation, and scarring of the lung tissues.
Types of diseases and conditions involved in intrinsic restrictive lung disease can include:
pneumonia
tuberculosis
sarcoidosis
idiopathic pulmonary fibrosis
interstitial lung disease
lung cancers
fibrosis caused by radiation
rheumatoid arthritis
infant and acute respiratory distress syndrome
inflammatory bowel disease (IBD)
systemic lupus
Extrinsic restrictive lung disease is caused by complications with tissues or structures outside
of the lungs, including neurological conditions.
External factors that cause an extrinsic restrictive lung disease are often associated with
weakened muscles, damaged nerves, or the stiffening of the chest wall tissues.
Types of diseases and conditions involved in extrinsic restrictive lung disease can include:
pleural effusions, or the buildup of excessive fluid between tissue layers surrounding the
lungs
scoliosis, or twisting of the spine
neuromuscular disease or conditions, such as Lou Gehrig's disease (ALS), multiple sclerosis,
and muscular dystrophy
obesity
myasthenia gravis, or intermittent muscle weakness
malignant tumors
rib damage, especially fractures
ascites, or abdominal swelling connected with liver scarring or cancer
diaphragm paralysis
kyphosis, or hunching of the upper back
diaphragmatic hernia
heart failure
Symptoms
Most people with restrictive lung diseases have similar symptoms, including:
shortness of breath, especially with exertion
inability to catch their breath or get enough breath
chronic or a long-term cough, usually dry, but sometimes accompanied by white sputum or
mucus
weight loss
chest pain
wheezing or gasping breath
fatigue or extreme exhaustion without a logical reason
depression
anxiety
Diagnosis
Doctors look at x-ray of lung.
Diagnosis will be based on a variety of tests, and in some cases scans such as x-rays.
A doctor will normally perform or order a pulmonary function test to assess total lung
capacity (TLC), or the total amount of air the lungs take in when a person inhales. The total
lung capacity is usually decreased in restrictive lung disease.
Other tests may be necessary for a full diagnosis and to ensure the correct treatment plan is
arranged. The specific tests used are usually determined by whether the suspected cause of
the restrictive lung disease is intrinsic or extrinsic.
Tests that show reduced lung functioning may indicate that scarring, stiffening, or
inflammation is affecting a large portion of the lungs.
Commonly used tests for restrictive lung disease include:
Forced vital capacity (FVC) test, which involves inhaling and filling the lungs with as much
air as possible, then exhaling with as much force as possible. The FVC of those with
restrictive lung diseases is typically decreased. A FVC value of less than or equal to 80
percent of what is expected can be a sign of a restrictive disease.
Forced expiratory volume in 1 second (FEV1) test, which measures the amount of air exhaled
during the first second of the FVC test. Most people expel about three-quarters of the air
inhaled during this initial period of exhalation. In restrictive disease, because the FVC is
usually reduced, the FEV1 will be lower, proportionally.
FEVI to FVC ratio test, which compares the amount of air expelled during the first second of
exhalation (FEV1) to the total amount of air exhaled during an FVC test. This ratio is often
normal or even increased in those with restrictive lung disease.
Chest X-ray, which creates images of the entire chest and lung area for evaluation.
Computed tomography (CT) scans, which create more detailed images of the chest and lung
area compared to chest X-rays.
Bronchoscopy, where a flexible tube with a camera is inserted through the nose or mouth into
the airways of the lung for examination.
Treatment
Treatment plans depend on the cause or the type of restrictive lung disease.
In some cases, delivering oxygen to a person using oxygen therapy may be necessary to help
them breathe properly.
In severe cases, lung transplant surgery, corrective surgery, or stem cell therapy may be
options.
Medications commonly used to treat restrictive lung diseases include:
azathioprine
cyclophosphamide
corticosteroids, usually in an inhaler form
methotrexate
other immunosuppressing and anti inflammatory medications
anti-scarring medications, such as pirfenidone or nintedanib
Unfortunately, a majority of the scarring, thickening, or loss of elasticity associated with
restrictive lung diseases is irreversible. There are ways, however, to reduce the symptoms or
impact of restrictive lung diseases.
Doing at-home exercises and making some lifestyle changes have been shown to reduce the
severity of restrictive disease symptoms.
Commonly recommended methods include:
breath conditioning, often pursed lip breathing, slow-deep breathing, or diaphragmatic
breathing
upper and lower limb strengthening and conditioning exercises
respiratory muscle strengthening exercises
level walking
relaxation or visualized meditation
eating a balanced, nutritious diet
quitting smoking
avoiding environments with toxins, irritants, or allergens that may worsen symptoms
Following a treatment plan and sticking to certain lifestyle changes can help alleviate the
symptoms of a restrictive lung disease and improve a person's quality of life.
