Malnutrition is poor nutrition due to an insufficient, poorly balanced diet, faulty digestion or poor utilization of foods. (This can result in the inability to absorb foods).
Malnutrition is not only insufficient intake of nutrients. It can occur when an individual is getting excessive nutrients as well.
Malnutrition is the condition that develops when the body does not get the right amount of vitamins, minerals, and other nutrients it needs to maintain healthy tissues and organ function.

Iodine Deficiency Disorders refer to a spectrum of health consequences resulting from inadequate intake of iodine. The adverse consequences of iodine deficiency lead to a wide spectrum of problems ranging from abortion and still birth to mental and physical retardation and deafness, which collectively known as Iodine Deficiency Disorders (IDDs).
Infant and young child feeding ppt describe the nutritional needs of infant and child. Exclusive breastfeeding for six months and complementary feeding for the child. avoid formula feeding for the child and continue breastfeeding for 24 months.
Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as cretinism due to untreated congenital hypothyroidism, which results in developmental delays and other health problems.

INTRODUCTION
Malnutrition is a state of nutrition in which;
a deficiency or excess or imbalance of energy, protein and other nutrients. causes measurable adverse effects on tissue / body form.
A malnourished person finds that their body has difficulty in growing and resisting disease.
Physical work becomes problematic and even learning abilities can be diminished.
For women, pregnancy becomes risky and they cannot be sure of nourishing the baby.
When a person is not getting enough food or not getting the right sort of food, they will become malnourished if the food they eat does not provide the proper amounts of micronutrients - vitamins and minerals - to meet daily nutritional requirements.
This ppt was made by my friend Svenia & I. It is a summary of the journal on 'Influence of mineral and vitamin supplements on pregnancy outcome'.
Hope it helps.
Nutritional & hormonal imbalance in children with Cerebral Palsy jitendra jain
Most of the time children with cerebral palsy suffer from some or other nutritional problems, some time it may be nutritional deficiency and others may have excess of that. hormonal imbalance also lead to lots of nutritional issue and growth problem in children with cerebral palsy. it is very important to understand each and every important step in nutritional requirement of these children so that parents can make fine balance in that for better growth.
Healthcare organizations including hospitals were founded to give care to those who need it and to keep patients safe.
It is generally agreed upon that the definition of patient safety is…
"DO NO HARM"
Diet does not substitute drugs but it is considered a complementary therapy.
The goals of dietary advice are:
To prevent or manage some medical conditions
To maintain or improve health through the use of appropriate and healthy food choices
To achieve and maintain optimal metabolic and physiological outcome
Adequate diet:
A mixture of food stuffs selected to satisfy the nutritional requirements of the body in quality and quantity. It should be safe and of good taste and smell. It should be suitable for weather age, effort and physiological status of every one.
Nutrition: it is the dynamic processes by which the body can utilize the consumed food for energy production, growth, tissue maintenance and regulation of body functions.
Is the ability to access, assess and apply the best evidence from systematic research information to daily clinical problems after integrating them with the physician's experience and patient's value.
Sample is Group of individuals or things selected from the entire population to be representative to this population.
Each member of the population is called the sampling unit.
Workplace Mental Health (WMH) is a sub-discipline concerned with psychological illness, injury and disability and the role of work as a causal or contributing factor. But, unfortunately, WHO announced that WMH is a ‘Cinderella’ subject. So, it is one of the most urgent demands facing the occupational health services (OHS).

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

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.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

3. MALNUTRITION
• Poor nutrition due to an insufficient, poorly balanced diet,
faulty digestion or poor utilization of foods. (This can result
in the inability to absorb foods).
• Not only insufficient intake of nutrients. It can occur when
an individual is getting excessive nutrients as well.

dependent on others for
their nourishment
(infants, children, the
elderly, prisoners….etc)
Mentally disabled or ill
because they are not
aware of what to eat.
People who are
suffering from TB,
eating disorders,
HIV/AIDS, cancer, or
who have undergone
surgical procedures
“interferences with
appetite or food
uptake”.
7. CAUSES OF MALNUTRITION

84. Definition: it is excess adipose tissue in different parts in the body due
to excess storage of fat.
The ability to store fat is unlimited but if the amount of fat to be stored
exceeds the ability of the fat cells to expand (50 times its size), the
body forms new adipose cells. With weight loss, fat cells decrease in
size but NOT in number. Once a fat cell formed, it exists for life.
85.
86.
87. ETIOLOGY (OF SIMPLE OBESITY):
Imbalance between energy intake & energy
expenditure for long periods of time.
91. A. Biological factors (Non-modifiable):
1. Genetics:
Brown adipose tissue (BAT): interscapular adipose tissue and
along the aorta. Thin persons have more brown adipose tissue, so
that fat oxidized more than stored.
92.
93.
94.
95.
96. Leptin “satiety factor”
It is a hormone secreted from adipocytes with central control from
hypothalamus. Suppress appetite, deplete fat stores & ↑ energy
expenditure.
In obesity there is a state of leptin resistance at cell level with
hyperleptinaemia → complications as CVDs.
97. Gremlin hormone
Hormone produced in the stomach. Its secretion stimulated by
adrenaline & nor-adrenaline which are released in response to
hypoglycemia where it promotes the appetite.
98. 2. Age: Obesity may appear at any age but obesity in
childhood is predictive to obesity later on adulthood.
3. Sex: Both sexes are exposed. Pregnancy causes ↑ in mother
weight by 4-6 pounds over her pre-pregnancy weight.
Menopause represents a risk period for extra weight gain and
redistribution of fat towards visceral regions.
99. B. Behavioral factors (modifiable factors):
Diet: Eat more than
need in Quality &
Quantity:
↑Sweets, fats, snacks &
soft drinks .
Nibbling in between
meals.
Evening overeating.
Physical inactivity:
Sedentary occupations,
preferring indoor life &
with least activity.
Psychological &
emotional disorders:
Anxiety, Stress &
Depressive illness
“emotional relieve”.
100. C. Environmental factors (modifiable factors):
Family lifestyle & feeding pattern Work problems & unemployment
Advanced technology Foods advertisements
103. A. QUALITATIVE ASSESSMENT:
Fat distribution in the body which is of morbid significance:
Pear-shaped obesity
(gynacoid)
Females “fat in hips &
thighs”.
Apple-shaped obesity
(android)
Males “fat around waist &
abdomen”.
107. 3. Relative weight:
(RW=body weight "kg"/desirable body weight "kg" x 100)
• RW is supposed to be 100%.
• Desirable body weight for each height is obtained from
special tables.
• RW > 120% is considered obesity.
108. 4. Waist/hip ratio (WHR):
if > 85%: android obesity “more health hazards as
cardiovascular problems”.
If <85% : gynacoid obesity.
109.
110. 5. Arm Fat Area (AFA):
It is a measure of total body fat (fat weight) and calculated from
mid-arm circumference and triceps skin fold thickness by certain
equation as :
AFA = Arm area - Arm muscle area.
111. 6. Hydrostatic water weighing
(densitometry):
It is comparing of body weight on
standard scale with the weight
underwater. By assuming that adipose
tissue is less dense than lean tissue
(muscles & bones), so the more adipose
tissue in a body, the less its underwater
weight (the more it tends to float). It is
an accurate method for estimating the
total body fat.
115. I) Lifestyle modification:
Diet: decreasing caloric intake by about 500 Kcal./day to achieve a weight
loss of 450 gm/week. Because of the way the body uses fuel from
carbohydrates, fats and protein, a more rapid weight loss will compel the
body to use protein (muscles) instead of fat for energy. This will decrease
muscle mass with each dieting attempt and fat percentage will increase.
Other principles of healthy eating relevant to weight loss:
Eat plenty of
food rich in
starch and fibers.
Eat plenty of
fruits and
vegetables.
Avoid eating too
much fat and
sugars.
Not skip meals
“suppress
metabolism”.
116. 2. Physical activity:
Walking or swimming are safe exercise for all persons.
Those who are bed ridden or are in wheel-chairs can use upper arm exercises.
Aerobic exercises require more air & tend to use the highest % of body fat for
fuel.
↓ body fat while helping
to preserve muscles
tissue tone.
Manage mental stress. ↑ energy levels Control of appetite
Improve blood sugar
control in diabetes.
↓ Blood pressure. ↑Amounts of HDL-C.
Improve bone density
where weight-bearing
exercises can slow down
bone loss after
menopause or even ↑
bone density.
117. 3. Behavioral modification:
By focusing on small, gradual behavioral changes, the
individual learns to gain control on eating behaviors with
the goal of permanent changes in eating habits.
Some basic strategies can be useful in promoting behavior changes for
sustained weight loss include:
Self-monitoring
Behavioral
contracting
Stimulus control
(precedes eating)
Cognitive
restructuring
Stress
management
Social support Physical activity
Relapse
prevention
118. II) Medications:
• Control obesity “appetite suppression or prevention of fat absorption”.
• Supplementation of vitamins & minerals
• Management of obesity complications.
119. III) Surgery:
It is used in cases of morbid obesity (BMI > 40) or in
cases of failure of other methods to control of obesity.
122. Cardiovascular “Main cause of death in obese”
• Coronary heart disease: Hyper-insulinaemia (insulin
resistance)& Hypertriglyceridemia (dyslipidemia).
• Hypertension ↑ renal sodium retention & catecholamines
release.
Diabetes mellitus
• Insulin resistance syndrome: due to defect in the insulin
receptors at the cell level leading to inability of the
body cells to utilize blood sugar to give the needed energy
Other complications
• Musculoskeletal disorders, gout,
• Cancer (colon, breast)
• Gall stones, hernias & Menstrual irregularities
