This document discusses the obesity epidemic and various factors contributing to it, including carbohydrates, environmental factors, genetics, and changes in food systems and physical activity levels. It notes that obesity is defined using BMI levels and presents data on obesity rates in countries like the US, Egypt, and globally. It examines hypotheses around causes like increased caloric intake and decreased physical activity, finding limited evidence supporting either. Instead, it argues the prime driver is changes in the environmental factors like food marketing, transportation, and agriculture that have promoted overconsumption of calories. Family influences and low socioeconomic status may also increase risk by limiting healthy options.
This document defines and classifies carbohydrates. Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen that include sugars, starches, and fibers. They are classified into monosaccharides, oligosaccharides, and polysaccharides. Monosaccharides are simple sugars that cannot be broken down further, while oligosaccharides contain 2-10 monosaccharide units and polysaccharides contain over 10 units and are not sweet tasting. Common monosaccharides include glucose and fructose, while examples of polysaccharides are starch, glycogen, cellulose, and chitin. Carbohydrates serve as energy sources for cells and as structural materials in plants.

NutritionIntroduction, Balanced Diet, Calorie, Caloric Value, Energy Content...Maryam Fida
This document discusses nutrition and energy balance in the human body. It defines a balanced diet as one containing proper proportions of carbohydrates, fats, proteins, vitamins, minerals, and water for good health. The three macronutrients that provide energy are carbohydrates, proteins, and fats, while vitamins and minerals are called micronutrients. The basal metabolic rate accounts for 60% of the total daily energy expenditure in the body and represents the calories needed for basic functioning even at rest. Other factors like physical activity and food digestion account for the remaining calories expended daily.
- Carbohydrates provide energy and are composed of carbon, hydrogen, and oxygen. Glucose is a primary carbohydrate that our bodies use for energy.
- Carbohydrates exist as monosaccharides, disaccharides, and polysaccharides. Monosaccharides like glucose cannot be broken down further. Disaccharides contain two monosaccharide units joined by a glycosidic bond. Polysaccharides contain long chains of monosaccharide units.
- Examples of monosaccharides are glucose, fructose, and galactose. Disaccharides include sucrose, lactose, and maltose. Starch, glycogen, and cellulose are examples of polysaccharides that provide energy storage or structural support
This document summarizes the history of nutritional science from 1785 to 1985. Some key developments include:
- In 1747, James Lind discovered that lime juice prevented scurvy in sailors, establishing the concept that specific dietary factors are necessary for health.
- In the 1800s, scientists like Magendie, Boussingault, and Liebig identified protein, nitrogen, carbohydrates, fats, and amino acids as essential dietary components.
- In the late 1800s and early 1900s, scientists discovered many vitamins including A, C, D, E, K, B1, B2, B6, B9, B12, and identified deficiency diseases like beriberi and pell
This document provides an overview of carbohydrates. It begins by defining carbohydrates as the most abundant organic compounds in plants, acting as energy stores and structural components. It then discusses monosaccharides, disaccharides, and polysaccharides. Specific carbohydrates discussed include glucose, fructose, sucrose, maltose, lactose, starch, glycogen, cellulose, and chitin. It explains their structures, functions, and important properties. The document is a comprehensive introduction to carbohydrate chemistry.
The document presents a lipid presentation covering the objectives, chemistry, structure, classification, properties and roles of lipids. It discusses the three main classes of lipids - simple lipids like fatty acids and acylglycerols, compound lipids including phospholipids, and derived lipids such as steroids, terpenoids and carotenoids. Key points covered include the composition of lipids from fatty acids and glycerol, their insolubility in water, roles in energy storage and cell membrane structure, and examples like cholesterol.
This document provides an overview of carbohydrates including sugars, starches, glycogen and fiber. It discusses how plants synthesize carbohydrates through photosynthesis and how the human body processes and uses carbohydrates as an energy source. Carbohydrates are broken down into glucose which fuels the brain and nervous system. The document also examines the importance of fiber, whole grains and the health effects of different types of carbohydrates.
The document discusses the Glycemic Index, which ranks foods based on how quickly they raise blood sugar levels after consumption. A high GI means blood sugar rises quickly, while a low GI means it rises slowly and stays steady. High GI foods break down rapidly, causing blood sugar fluctuations, while low GI foods break down slowly for stable blood sugar levels. However, a low GI food is not necessarily nutritious if it contains unhealthy ingredients like saturated fat or lacks nutrients. An overall balanced diet and exercise are most important for health.
Food fortification involves adding essential nutrients to foods in order to prevent nutritional deficiencies in the population. Common foods fortified include wheat flour, rice, oils, salt and cereals by adding vitamins A, D and minerals like iron and iodine. Fortification can be done through various methods like biofortification of crops, home fortification by adding micronutrient powders to foods, or commercial and industrial fortification during food processing. While fortification improves nutrition and health, limitations include not all population groups benefiting and nutrient interactions affecting absorption. Current focus is on both reducing deficiencies and promoting overall health.
Dietary fiber comes from plant foods and is not digested by humans. There are two types: insoluble fiber aids digestion, while soluble fiber can lower cholesterol. Fiber promotes regularity, aids weight loss, and may reduce cancer risk. The recommended daily fiber intake is 20-35 grams, but most people consume only about 15 grams. Good sources of fiber include whole grains, fruits, vegetables, beans, and nuts. Increasing fiber intake gradually and drinking water can help avoid digestive issues.

Direct and Indirect Calorimetry, Carbon & Nitrogen Balance StudiesKaushalendra Kumar
This document discusses methods for measuring heat production and energy retention in animals, including direct calorimetry, indirect calorimetry using respiratory exchange measurements, and carbon and nitrogen balance studies. Direct calorimetry involves housing animals in insulated chambers and measuring heat loss, while indirect calorimetry estimates heat production from oxygen consumption and carbon dioxide production. Carbon and nitrogen balance studies estimate energy retention by measuring intake and output of carbon and nitrogen.
Dietitians provide food and nutrition information, and support people to improve their health. They provide advice on nutrition-related matters. Dietitians can also change diets to help manage conditions such as: diabetes
This document provides information about different types of dietary fats and cholesterol. It discusses saturated and unsaturated fats, including monounsaturated and polyunsaturated fats. It also explains how cholesterol is carried in the blood by LDLs and HDLs, and that LDLs are linked to heart disease while HDLs help remove cholesterol from arteries. The document recommends no more than 66g total fat, 30% calories from fat, and less than 10% calories from saturated fat for a 2000 calorie diet.
The document provides information on lipids including their structure, types, functions in food and the body, digestion, and health impacts. It discusses saturated, unsaturated, and trans fats. It also covers lipid metabolism, recommendations for athletes, and factors that influence fat oxidation during exercise like fitness level, exercise intensity and duration, and diet.
Obesity is defined as excess body fat that may negatively impact health, and can be caused by overeating, underexercising, genetics, age, sex, economic factors, and psychology. Diseases linked to obesity include diabetes, heart disease, high blood pressure, stroke, cancer, and others. Physical complications of obesity range from heart disease and diabetes to cancer, gallbladder disease, and osteoarthritis. The document also notes that portion sizes at restaurants are much larger than at home, children spend significant time using media, and obesity is linked to lower life expectancy.
Worldwide, obesity nearly tripled since 1975, with over 650 million adults and 340 million children classified as obese in 2016. Obesity is defined as abnormal fat accumulation that impairs health, measured as a BMI over 30 for adults and over 2 or 3 standard deviations for children depending on age. The fundamental causes of obesity are an energy imbalance from increased intake of unhealthy foods and decreased physical activity due to sedentary lifestyles. Obesity raises the risk of diseases like heart disease, diabetes, and certain cancers. Reducing obesity involves limiting unhealthy foods, increasing physical activity, and for some, bariatric surgery.
World hunger and malnutrition remain devastating problems, affecting nearly 30% of humanity. Malnutrition causes 60% of deaths among children under 5 in developing countries and contributes to increased risk of chronic disease. While undernutrition and micronutrient deficiencies persist, chronic diseases linked to obesity are emerging globally as a major public health threat, dominating mortality in 5 of 6 WHO regions. The WHO calls for addressing the whole spectrum of malnutrition as both a human need and basic right.
This document discusses Type 1 diabetes, including that it is an autoimmune disease where the body attacks the insulin-producing cells in the pancreas. It affects people of all ages but is usually diagnosed in children and young adults. The document outlines the symptoms, causes, treatment, risks, and interesting facts about Type 1 diabetes.

4) Both undernutrition and overnutrition pose health challenges, with a shift needed toward more nutritious diets.
This document discusses diabetes in pregnancy. It covers the epidemiology of gestational diabetes and types 1 and 2 diabetes in pregnancy. It describes the pathophysiology of how pregnancy causes insulin resistance and increased glucose levels. It then discusses the fetal and maternal risks of poorly controlled diabetes in pregnancy, including miscarriage, birth defects, macrosomia, hypoglycemia, and preeclampsia. The diagnosis and treatment of gestational diabetes focuses on glucose challenge tests, glucose tolerance tests, and insulin therapy to control blood sugar levels and minimize complications.
1. Obesity is associated with female and male infertility through multiple mechanisms that impact the hypothalamic-pituitary-gonadal axis, gamete quality, embryo development, implantation, and pregnancy outcomes.
2. For females, obesity is linked to irregular menstrual cycles, ovulation disorders, polycystic ovary syndrome, and impaired endometrial receptivity. It can decrease fertility, increase miscarriage risk, and lead to poorer outcomes with assisted reproduction.
3. For males, obesity is associated with decreased testosterone and sperm quality, as well as erectile dysfunction. Weight loss through lifestyle changes and bariatric surgery can help address obesity-related infertility issues.
The document investigates the role of diet in the rising rates of breast cancer. It discusses how the Vegetarian & Vegan Foundation (VVF) aims to understand why breast cancer cases are increasing by examining potential dietary factors like red meat, animal fat, and hormones/growth factors in cow's milk. The VVF seeks to educate the public about how making plant-based dietary choices could help lower breast cancer risk.
The document discusses childhood obesity and its causes. It notes that obesity rates have risen sharply over the past few decades due to dietary changes. Recommendations in the 1980s to reduce fat intake and emphasize carbohydrates have paradoxically contributed to weight gain and associated health issues like diabetes. Current research suggests dietary fat and protein are more satiating than carbohydrates and do not raise insulin levels in the same way. A balanced, less carbohydrate-focused diet may help address obesity and related diseases.
This document discusses the causes, costs, and cures of obesity. It explores the nature vs nurture debate around obesity and examines genetic and environmental factors. It outlines the health impacts of a sedentary lifestyle and poor nutrition, including increased risks of diabetes, cancer, heart disease, and more.

This document discusses the diabetes and obesity epidemics. It argues that type 2 diabetes is caused by the body's inability to properly metabolize fats and oils, rather than carbohydrates as traditionally believed. The rise of type 2 diabetes in the 1930s coincided with the introduction of processed vegetable oils and hydrogenated fats into the food supply. While early physicians recognized diet could treat this "insulin-resistant diabetes", later medical groups advised high-carb, low-fat diets that have exacerbated the epidemics. The document advocates replacing processed fats with healthy natural fats.
Over the past few decades, diabetes has emerged as an important global health problem. A recent report projected that the worldwide prevalence of diabetes among all age groups would increase from 2.8% in 2000 to 4.4% in 2030. The greatest increases would occur in developing regions. Important contributors to the rise in diabetes include increased urbanization and aging populations. Diabetes results from a lack of insulin or ineffective insulin and causes damage to various organs over time if not properly managed. The document further discusses the classification, presentation, risk factors, genetic components, treatments and nutritional management of diabetes.
The document discusses diabetes trends globally and provides information on the classification, presentation, and risk factors of diabetes. It notes that worldwide diabetes prevalence is expected to increase significantly by 2030, with most of the growth occurring in developing regions. The two main types of diabetes - type 1 and type 2 - are described, with type 2 accounting for 90-95% of cases. Risk factors for type 2 diabetes include genetics, obesity, diet, and lifestyle factors. Carbohydrate intake and dietary fiber intake are discussed as dietary risk factors.
The document discusses how fat tissue is essential but obesity has become a worldwide epidemic. It describes several factors that have contributed to increased obesity rates, including changes to the human diet with the introduction of cereal grains, refined sugars and oils through agriculture, a more sedentary lifestyle, and genetic factors. The rise in obesity is linked to various metabolic diseases like type 2 diabetes, dyslipidemia, and insulin resistance.

Pre-travel advice includes preparation for chronic conditions, carrying sufficient medication supplies, extra eyewear, first aid kits, and preventive medications.
This document discusses the health effects of passive smoking on children. It begins by providing epidemiological data on smoking rates in Egypt, noting that almost half of Egyptian men and 20-29% of Egyptian women smoke. It then discusses 25 different health effects that passive smoking can have on children, including increased risk of respiratory illnesses like pneumonia, middle ear infections, and asthma. The risks also include lower birth weight, stunted growth, and sudden infant death syndrome. The document concludes by recommending policies to reduce tobacco use like increased taxation, banning advertising and smoking in public, and mass public education campaigns.
Logistic regression is a statistical model used to predict binary outcomes like disease presence/absence from several explanatory variables. It is similar to linear regression but for binary rather than continuous outcomes. The document provides an example analysis using logistic regression to predict risk of HHV8 infection from sexual behaviors and infections like HIV. The analysis found HIV and HSV2 history were associated with higher odds of HHV8 after adjusting for other variables, while gonorrhea history was not a significant independent predictor.
Hepatitis C is a major public health problem in the Arab world and North Africa with an estimated 25 million people affected. [1] Genotype 4 is most common in this region. [2] Major risk factors for transmission include blood transfusions, hemodialysis, healthcare procedures, and injection drug use. [3] Transmission within healthcare settings poses a risk, with one study in Egypt finding a 12.3% incidence of transient viremia in exposed healthcare workers. [4] Strategies are needed to improve infection control and screening measures to reduce the high prevalence of Hepatitis C in this part of the world.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

A recent study of 4,537 women and 5,004 men found that food insecurity was positively related to overweight in women. (Townsend MS, Peerson J, Love B, Achterberg C & Murphy SP, 2001)
Food insecurity was related to overweight in women (p&lt; 0.0001) but not in men (p&lt;0.44).
Food insecurity remained a strong predictor of overweight status after adjustment for potential confounding demographic and lifestyle variables (adjustments for the quality of food eaten in the household)
Overweight was defined as BMI&gt;27.3 for women and BMI&gt;27.8 for men.
Children need safe, inviting, well-lit places to play – may not exist in some neighborhoods
Some schools’ PE programs may not be up to par – especially in disadvantaged communities.
Low SES populations (especially single parents) may not have the time nor the money to dedicate to physical activity
