Protein-energy malnutrition (PEM) and obesity are both types of malnutrition that result from imbalances in nutrient intake and energy expenditure. PEM specifically refers to deficiencies in protein and calories over long periods and can manifest as kwashiorkor or marasmus. Obesity is defined as abnormal or excessive fat accumulation that presents health risks. Groups vulnerable to PEM include children, pregnant/lactating women, older adults, and those with chronic illnesses. PEM is diagnosed based on growth monitoring, dietary history, and anthropometric measurements. Prevention focuses on nutrition education, supplementation, and treating infections early. Risk factors for obesity include age, genetics, physical inactivity, diet, and socioeconomic status. Obesity is assessed using body mass index

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.
The dimensions of healthcare quality refer to various attributes or aspects that define the standard of healthcare services. These dimensions are used to evaluate, measure, and improve the quality of care provided to patients. A comprehensive understanding of these dimensions ensures that healthcare systems can address various aspects of patient care effectively and holistically. Dimensions of Healthcare Quality and Performance of care include the following; Appropriateness, Availability, Competence, Continuity, Effectiveness, Efficiency, Efficacy, Prevention, Respect and Care, Safety as well as Timeliness.

Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

2. MALNUTRITION
Definition: Excess or deficiency of nutrient rich food in diet is called malnutrition.
According to WHO, Malnutrition is define as "the cellular imbalance
between the supply of nutrients and energy and the body's demand for them to
ensure growth, maintenance and specific functions

4. 4
Protein-Energy Malnutrition
Protein-energy malnutrition is a type of malnutrition resulting from deficiency of
proteins and calories in the food over a long period of time.
The most serious forms of PEM are kwashiorkor and marasmus. Nutritional
marasmus is more frequent than kwashiorkor.
Causes:
• Decreased intake of food
• Excessive loss of proteins and calories
• Increased demand and decreased absorption and utilization.
• Infection contributes to malnutrition & malnutrition pre- disposes to causation of
infection
• Social factors: such as poverty, illiteracy, ignorance, overcrowding, large family size,
poor maternal health, failure of lactation.

Diagnosis of PEM
The first indicator of PEM is underweight for age.
This can be measured by comparing growth
charts for different age groups.
It can be diagnosed by identifying dietary history
of the patient.
Anthropometric measurement of body should
be examined.
Mid-arm circumference (MAC) has been
extensively used at 1-5 years of age as an age-
independent indicator of protein-energy
malnutrition (PEM).
9. Prevention and control of protein-energy malnutrition in the community
Health promotion:
• Nutritional care of pregnant mothers to prevent LBW.
• Nutritional care of lactating mothers to prevent subsequent malnutrition
during infancy and childhood.
• Promotion of correct breastfeeding practices.
• Frequent feeds to a growing child.
• Improvement in the living condition.
• Supplementary feeding program for mothers and children.
Specific protection:
• Protein- and energy-rich diet for a growing child (i.e. diet containing milk, egg,
fruits, etc.)
• Immunization
• Fortification of food
9
10. Early diagnosis and treatment of PEM:
• Periodic surveillance
• Early diagnosis of any lag in growth
• Early diagnosis and treatment of infections and diarrhoea
• Development of programmes for early rehydration of children's with
diarrhoea.
• Development of supplementary feeding programmes during epidemics.
• Deworming of heavily infested children.
10
11. OBESITY
Definition: it is a type of nutritional disorder, due to imbalance between energy
intake and energy expenditure, resulting in positive energy balance, characterized
by the abnormal growth of the adipose tissue, resulting in an increase in the body
weight to the extent of 20% or more of the standard weight for the person's age,
sex, and height.
11
12. Risk Factors:
• Non modifiable:
1. Age: obesity can occur in any age-group, generally it increases with age.
2. Sex: obesity is more among the women, especially during the postmenopausal age,
between 45 years and 49 years.
3. Genetic factors: obesity tends to run in families, with obese children frequently having
obese parents.
• Modifiable
1. Physical activity: The physical activity pattern (including occupational work, household
work, and leisure time activity, such as sports and exercise) determines the food intake
and fat balance.)
5. Socioeconomic status: high socioeconomic status correlates positively with obesity in
the developing countries.
6. Eating habit: the composition of the diet, the periodicity of eating, and the amount of
energy obtained are relevant to the development of obesity.
7. Psychological factors: People who are under constant emotional strain find satisfaction
in eating the food.
12
13. Assessment of obesity:
• Corpulence Index:
• Body Mass index:
Note: Indian cut-off point for obesity is N=BMI=22.5 and globally 25
13
Corpulence Index=
𝐴𝑐𝑡𝑢𝑙 𝑤𝑒𝑖𝑔ℎ𝑡 𝑜𝑓 𝑡ℎ𝑒 𝑖𝑛𝑑𝑖𝑣𝑖𝑑𝑢𝑎𝑙
Exp𝑒𝑐𝑡𝑒𝑑 𝑏𝑜𝑑𝑦 𝑤𝑒𝑖𝑔ℎ𝑡 (𝐸𝐵𝑊)
BMI =
𝑊𝑒𝑖𝑔ℎ𝑡 𝑖𝑛 𝑘𝑔
(𝐻𝑒𝑖𝑔ℎ𝑡 𝑖𝑛 𝑚)2
14. • Waist Circumference:
This helps to measure abdominal fat. It is measured at a midpoint between
the lower border of the rib cage and the iliac crest. Waist circumference is
observed to be high among men with a waist circumference >102 cm and among
women >88cm.
• Waist-Hip Ratio:
It is accepted that WHR of more than 1.0 in men and 0.85 in women
indicates abdominal fat accumulation.

Coronary Heart disease
(RR 1-2)
Cancer
Gallbladder disease Hypertension Impaired fertility
Dyslipidaemia Osteoarthritis Low back pain
Insulin resistance Hyperuricemia and gout Fatal defects associated
with maternal obesity
16. Prevention and control:
16
1. Dietary changes:
• Refrain from over consumption of fats and carbohydrates.
• Diet should contains suitable proportion of cereals, legumes and vegetables,
fibre content should be increased.
• Food energy intake should not be greater than what is necessary for energy
expenditure.
2. Physical activity:
• Regular physical activity helps in increasing the energy expenditure, so
sedentary lifestyle should be discouraged.
3. Health Education:
• People are educated about hazard of obesity and its prevention by healthy diet
and lifestyle diet and lifestyle, to be promoted from early age.
4. Bariatric Surgery:
• Among those whose BMI is>40 & is not possible to control obesity with the
routine measures of exercise and change in the lifestyle practices.
