Physical activity Guidelines by WHO

WHO developed the "Global Recommendations on Physical Activity for Health" with the overall aim of providing national and regional level policy makers with guidance on the dose-response relationship between the frequency, duration, intensity, type and total amount of physical activity needed for the prevention of NCDs.

The recommendations address three age groups: 5–17 years old; 18–64 years old; and 65 years old and above.

Physical Activity and Young People (for children aged 5 - 17 years):

In order to improve cardiorespiratory and muscular fitness, bone health, and cardiovascular and metabolic health biomarkers:

1. Children and youth aged 5–17 should accumulate at least 60 minutes of moderate- to vigorous-intensity physical activity daily.
2. Amounts of physical activity greater than 60 minutes provide additional health benefits.
3. Most of the daily physical activity should be aerobic. Vigorous-intensity activities should be incorporated, including those that strengthen muscle and bone*, at least 3 times per week.

*For this age group, bone-loading activities can be performed as part of playing games, running, turning or jumping.

ü  These recommendations are relevant to all healthy children aged 5–17 years unless specific medical conditions indicate to the contrary.

ü  The concept of accumulation refers to meeting the goal of 60 minutes per day by performing activities in multiple shorter bouts spread throughout the day (e.g. 2 bouts of 30 minutes), then adding together the time spent during each of these bouts.

ü  For inactive children and youth, a progressive increase in activity to eventually achieve the target shown above is recommended. It is appropriate to start with smaller amounts of physical activity and gradually increase duration, frequency and intensity over time. It should also be noted that if children are currently doing no physical activity, doing amounts below the recommended levels will bring more benefits than doing none at all.

Physical Activity and Adults (physical activity for adults aged 18 - 64 years):

In order to improve cardiorespiratory and muscular fitness, bone health, reduce the risk of NCDs and depression:

1. Adults aged 18–64 should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity.
2. Aerobic activity should be performed in bouts of at least 10 minutes duration.
3. For additional health benefits, adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate- and vigorous-intensity activity.
4. Muscle-strengthening activities should be done involving major muscle groups on 2 or more days a week.

ü  These recommendations are relevant to all healthy adults aged 18–64 years unless specific medical conditions indicate to the contrary. They are applicable for all adults irrespective of gender, race, ethnicity or income level. They also apply to individuals in this age range with chronic non-communicable conditions not related to mobility such as hypertension or diabetes.

ü  There are multiple ways of accumulating the total of 150 minutes per week. The concept of accumulation refers to meeting the goal of 150 minutes per week by performing activities in multiple shorter bouts, of at least 10 minutes each, spread throughout the week then adding together the time spent during each of these bouts: e.g. 30 minutes of moderate-intensity activity 5 times per week.

ü  Pregnant, postpartum women and persons with cardiac events may need to take extra precautions and seek medical advice before striving to achieve the recommended levels of physical activity for this age group.

ü  Inactive adults or adults with disease limitations will have added health benefits if moving from the category of “no activity” to “some levels” of activity. Adults who currently do not meet the recommendations for physical activity should aim to increase duration, frequency and finally intensity as a target to achieving them.

Physical Activity and Older Adults (physical activity for adults aged 65 and above):

In order to improve cardiorespiratory and muscular fitness, bone and functional health, reduce the risk of NCDs, depression and cognitive decline:

1. Older adults should do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week or do at least 75 minutes of vigorous-intensity aerobic physical activity throughout the week or an equivalent combination of moderate- and vigorous-intensity activity.
2. Aerobic activity should be performed in bouts of at least 10 minutes duration.
3. For additional health benefits, older adults should increase their moderate-intensity aerobic physical activity to 300 minutes per week, or engage in 150 minutes of vigorous-intensity aerobic physical activity per week, or an equivalent combination of moderate-and vigorous-intensity activity.
4. Older adults, with poor mobility, should perform physical activity to enhance balance and prevent falls on 3 or more days per week.
5. Muscle-strengthening activities, involving major muscle groups, should be done on 2 or more days a week.
6. When older adults cannot do the recommended amounts of physical activity due to health conditions, they should be as physically active as their abilities and conditions allow.

ü  These guidelines are relevant to all healthy adults aged 65 years and above. They are also relevant to individuals in this age range with chronic NCD conditions. Individuals with specific health conditions, such as cardiovascular disease and diabetes, may need to take extra precautions and seek medical advice before striving to achieve the recommended levels of physical activity for older adults.

ü  There are a number of ways older adults can accumulate the total of 150 minutes per week. The concept of accumulation refers to meeting the goal of 150 minutes per week by performing activities in multiple shorter bouts, of at least 10 minutes each, spread throughout the week then adding together the time spent during each of these bouts: e.g. 30 minutes of moderate-intensity activity 5 times per week.

ü  Older adults who are inactive or who have some disease limitations will have added health benefits if moving from the category of “no activity” to “some levels” of activity. Older adults who currently do not meet the recommendations for physical activity should aim to increase duration, frequency and finally intensity as a target to achieving them.

Note: These recommendations can be applied to people with disabilities. However, adjustments for each individual based on their exercise capacity and specific health risks or limitations may be needed.

public health solution for malaria - Gene manipulated mosquitos?

British scientists have manipulated the genes of a specific type of mosquito so that only male offspring is produced and the animals are eliminated within several generations. "Nature Communications".

In order to inhibit the production of female offspring among the mosquitos (Anopheles gambiae), the researchers from Imperial College London used the enzyme I-Ppol. In males, it damages the DNA of the X chromosomes in sperm production. Thus, the modified mosquitos had almost no functional sperm with X chromosomes and produced 95 per cent male offspring.

The scientists mixed the genetically modified insects with five caged normal mosquito populations. Because of the lack of females, four of them were entirely eliminated within six generations. This way, malaria-carrying mosquitos could be eliminated in the wild. However, no research was undertaken as to which consequences this may have on the ecosystem.

"What is most promising about our results is that they are self-sustaining. Once modified mosquitoes are introduced, males will start to produce mainly sons, and their sons will do the same, so essentially the mosquitoes carry out the work for us", said study author Nikolai Windbichler.

Medical negligence and compensation, time to have more practical approach

From: thehindubusinessline.com

Body blow to the medical profession

Compensation for medical malpractice should be capped. Else, there will be no doctors left to perform surgeries
The recent Supreme Court ruling on medical compensation of ₹11 crore in Kolkata has raised several issues related to the medical profession and its practice. The Supreme Court has rightly upheld the law of the land.

In 2030 BC, during the Old Babylonian period, the Code of Hammurabi read: “If the doctor has treated a gentleman with a lancet of bronze and has caused the gentleman to die or has opened an abscess of the eye for a gentleman with a bronze lancet and has caused the loss of the gentleman’s eye, one shall cut off his hands”.

Chopping off doctor’s hand for making a mistake is definitely effective but after some time there will be few doctors left with the hands to operate. The current Indian law governing the medical negligence is not vastly different than that of Hammurabi’s Code.

Gynaecologists will retreat
And, what is the state of healthcare delivery in India? As many as 84 per cent of the hospitals in India are less than 30 beds in size, where more than 60 per cent of the children of this country are born. Among doctors, gynaecologists are most vulnerable to litigation.

A majority of these nursing homes do not even have a medical records department to protect them in the case of litigation. Any sincere effort to save the life of a patient, not backed by a well documented medical record, can never stand in the court of law.

A gynaecologist builds a typical 30-bed nursing home in a small town after slogging for decades and building a reputation for himself and the nursing home.

However, if an unfortunate incident occurs and someone sues the gynecologist for ₹2 crore — which is not a lot of money compared to ₹11 crore compensation offered in Kolkata — there will be a problem.

Even if the small town gynaecologist sells his nursing home, his house and farmland, if he has any, he will not be able to come up with ₹2 crore.

Doctors, in general, are in a very insecure profession, since they are dealing with human life. We are now adding an angle of financial insecurity, which can potentially bankrupt the doctor and his family.

One or two stray incidents across the country claiming a compensation of ₹1 or 2 crore against these gynaecologists in small towns is good enough to send shock waves among the medical community.

The media spotlight is bound to amplify the impact. In a very short time most gynaecologists taking care of pregnant ladies in small towns will move to big hospitals in cities where they are protected.

If the issue is not addressed soon, we can expect maternal mortality to double.

Get real
Our policymakers boast of India having 6 lakh doctors. What they have not realised is that nearly two lakh doctors, instead of seeking invaluable learning by the patient’s bedside, are busy mugging MCQs (multiple choice questions) for two to five years in Kerala or Kota in pursuit of one of those elusive PG seats.

As a result, junior doctors doing night duty in small towns simply do not exist. Specialists in small towns are handicapped with very little support from junior doctors, trained nurses and technicians.

In the early 1990s the medical profession in the US was reeling under the impact of astronomical compensation for malpractice.

As expected, malpractice insurance premium went up to three months of doctors’ salary. The doctors decided to stop conducting deliveries. As a result, the government had to airlift pregnant ladies during childbirth from small towns to bigger city centres. Obviously, it was unsustainable and risky.

So, several states in the US capped malpractice compensation at $ 250,000 (₹1.5 crore). This capping reduced malpractice suits significantly. Today, the US has one lawyer for every 300 people! No wonder, one in every seven doctors is sued there every year. India is not too far behind; Delhi has one advocate for every 300 citizens!

Change the law
Capping compensation is not new to Indian law. Government officers cannot be fined for more than 33 per cent of their basic salary. In the US and several European countries, capping the malpractice compensation is a norm.

Human life is precious. Leave alone ₹11 crore, even if the family is paid ₹1,000 crore it cannot compensate for the loss of life. The only question is: What can we afford?

Of course, medical malpractice deserves punishment. Doctors who have neglected the patient are punished through the Medical Council, which can remove their right to practice temporarily or permanently, and this is one of the worst punishments for a doctor. Added to that some financial compensation is definitely required.

However, if the compensation is going to ruin the doctor, his family and his future, we are not far away from the rule of Hammurabi.

As a country, we need to protect everyone’s life. But if we try to implement first-world regulatory structure with third-world infrastructure, we will be in trouble. We are a country short of one million doctors, two million nurses and three million beds.

With this scarcity, we should concentrate more on improving the infrastructure, creating the right regulatory framework to protect the life of the patients as well as an ideal working environment for the doctors. On this issue, governments’ mandate should be to cap the malpractice compensation.

Compensating the family by ₹2 crore instead of ₹20 lakh will not revive a lost life. But it can wreck the doctor’s family and close down small nursing homes in backward areas, putting the lives of thousands of people at risk.

Professional bodies such as the Indian Medical Association and Association of Healthcare Providers of India (AHPI) should write to the Minister of Health to request the Ministry of Law to cap the malpractice compensation.

social obstetrics

Social obstetrics may be defined as the study of the interplay of social and environmental factors and human reproduction going back to the preconceptional or even premarital period. 

The social and environmental factors which influence human reproduction are many. 

Some examples include:

• age at marriage 
• child bearing
• child spacing
• family size 
• fertility patterns
• level of education
• economic status
• customs and beliefs
• role of women in society 

Social obstetrics has another dimension: the influence of these factors on the organization, delivery and utilization of obstetric services by the community. 

In other words, social obstetrics is concerned with the delivery of comprehensive maternity and child health care services including family planning so that they can be brought within the reach of the whole community.
