Nutritional epidemiology
This document discusses nutritional epidemiology, which is the study of nutritional determinants of disease in human populations. It defines nutrition as the science of how nutrients interact with the body and influence health and disease. Nutritional epidemiology examines the relationship between diet, health, and disease. Some key points made include:
- Epidemiological studies have shown relationships between low fruit/vegetable intake and cardiovascular disease and between saturated/trans fats and heart disease/diabetes.
- Studies established that increasing folic acid intake reduces the risk of neural tube birth defects.
- Objectives include disease prevention, monitoring population nutrient intake and status, and generating hypotheses about diet and disease.
Nutritional Surveillance
This document discusses nutritional surveillance. It begins with an introduction defining nutritional surveillance as the regular collection and analysis of nutrition data. It then outlines the purpose of nutritional surveillance, which includes monitoring nutrition situations, informing policies, and tracking program progress. The document also provides a brief history of nutritional surveillance and describes the process involving data collection, analysis, dissemination and decision making. It further discusses challenges and provides guidance on establishing nutritional surveillance systems.
Nutritional epidemiology
Nutritional epidemiology combines the knowledge of nutritionists with epidemiological methodology to study diseases with multiple causes. It aims to monitor nutrient intake and nutritional status in populations and contribute to disease prevention and public health. Some goals are assessing community nutritional status, conducting nutritional and dietary surveys, and monitoring nutrition and growth. Major diseases related to nutrition include mineral deficiency, protein-energy malnutrition, anemia, and over-intake of nutrients.
Nutrition Epidemiology
This document provides an overview of nutrition science, including definitions of key terms and descriptions of major nutrients. It discusses the study of nutrients and how the body processes them. Major topics covered include macronutrients like carbohydrates, fats, proteins, micronutrients like vitamins and minerals, nutrient deficiencies, and how genetics and genomics relate to nutrition and disease.
Public health nutrition
The document discusses various methods of nutritional assessment including clinical, biochemical, anthropometric, and dietary assessments.

DIETARY ASSESSMENT SEMINAR
This document provides an overview of general methods of dietary assessment. It discusses various methods used at both the individual and national level, including food balance sheets, 24-hour recall, food frequency questionnaires, weighed food records, and dietary history. It also covers the purposes of dietary assessment, such as improving individual diets, planning food strategies, and assessing nutrition programs. Limitations of different methods are outlined. National agencies involved in nutritional surveillance in India, such as the National Nutrition Monitoring Bureau, are also mentioned.
Nutrition surveillance
1. Nutrition surveillance systems collect, analyze, interpret and report on nutritional status data to inform emergency response strategies. They vary based on context and resources.
2. Key challenges include ensuring reliable, timely data and effective links between data and action. Interpreting data requires understanding local contexts and underlying causes of malnutrition.
3. The objectives of surveillance systems are advocacy, identifying responses, triggering actions, targeting at-risk areas, and identifying malnourished individuals. Representative data that monitors standard indicators is most useful.
Nutritional surveillance
Nutritional surveillance provides important inputs for health and development planning by monitoring food consumption and allowing for timely intervention to prevent food crises. It involves identifying at-risk populations, collecting and analyzing nutrition data, interpreting the results, and planning responses. The process is cyclical and aims to continually improve by implementing further actions based on evaluations. While growth monitoring tracks individual nutrition status, nutritional surveillance examines the broader community and environmental factors influencing a population's nutrition.

Here are the key points about food security dimensions and factors:
- Food security has 4 dimensions - availability, access, utilization, and stability.
- Availability depends on food production, stocks, and trade within a country.
- Access depends on purchasing power, income, markets, infrastructure, and prices.
- Utilization depends on nutrition, safety, diversity, and intra-household distribution of food.
- Stability means the other dimensions are stable over time and not at risk from things like shocks, poverty, conflict, or price fluctuations.
- Food insecurity can be chronic, recurring regularly due to poverty, or transitory from sudden events like conflict or weather disasters.

PRINCIPLES OF PUBLIC HEALTH NUTRITION PROGRAMME.pdf
This document outlines the principles of public health nutrition programs. It discusses several key points:
1. Effective public health nutrition programs are evidence-based, with interventions backed by needs assessments and evidence of effectiveness.
2. Programs aim to reduce health inequities and promote nutritional health and well-being of whole populations through organized community efforts.
3. Successful programs involve intersectoral collaboration between health, agriculture, and other sectors, as nutrition issues have multiple underlying causes. Community participation in program design and implementation is also important.
Biochemical Assessment PowerPoint
This document provides an overview of biochemical tests used to assess nutritional status. It discusses static tests that directly measure nutrients and functional tests that indirectly reflect nutrient deficiency. Protein status is challenging to evaluate but can be assessed via creatinine height index, nitrogen balance, albumin, prealbumin, and immunocompetence. Iron status involves ferritin, transferrin, hemoglobin, hematocrit, and red blood cell indicators. Common blood panels include CBC, metabolic, and lipid to evaluate nutrients, minerals, enzymes, and metabolites. Biochemical tests are useful but have limitations, so a comprehensive evaluation is best.
Nutrition transition-presentation-2018-final
The document discusses the nutrition transition, defined as the shift in dietary consumption and energy expenditure that accompanies economic, demographic, and epidemiological changes. It outlines the 5 stages of the nutrition transition: 1) collecting food, 2) famine, 3) receding famine, 4) nutrition-related non-communicable diseases, and 5) behavioral change. Urbanization is contributing to nutrition transitions in developing countries as diets shift toward more processed foods and a more sedentary lifestyle. This nutrition transition is creating a double burden of disease and negatively impacting health systems in developing nations.
Lec 2 community dietary assessment

This document discusses public health nutrition and its importance for health promotion and protection. It assesses factors that influence eating behaviors such as hunger, appetite, culture, habits, emotions, and advertising. It defines nutrition as the science of the relationship between physiological functions and essential food elements. Key nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water. Child malnutrition rates in Bangladesh are very high, and dietary habits and food practices need to change to improve nutrition status. A balanced diet is important for a healthy life.
Nutrition in emergency
This document provides guidelines for nutrition in emergency situations. It discusses the importance of the right to food and adequate nutrition during crises. An emergency food ration should aim to meet 2100 kcal per person per day as well as macronutrient and micronutrient requirements. The ration must be tailored based on factors like climate and population. Special consideration is given to vulnerable groups like infants, children, pregnant and lactating women, and older persons. Food fortification, substitution, and other management strategies are also outlined. Monitoring is key to adjusting the ration as the crisis and people's needs evolve over time.
Diet and Nutrition - Prevention of Chronic Diseases
Diet plays a major role in chronic disease prevention. The document summarizes how diets are changing globally to incorporate more animal fats and sugars. Various chronic diseases like obesity, diabetes and heart disease are linked to diet, with excessive weight gain and physical inactivity increasing risks. Recommendations include consuming at least 400g of fruits and vegetables daily, limiting fat and sugar intake, and engaging in moderate physical activity to help prevent chronic diseases and promote overall health.
Lecture 3 food insecurity
Food insecurity remains a global challenge. Achieving food security requires accurately measuring the incidence, nature, and causes of food insecurity. This allows for prioritizing interventions and targeting assistance. Conceptual frameworks help analyze the complex underlying causes of food insecurity and guide appropriate responses. Understanding factors like availability, access, utilization, and stability is key to selecting interventions to address problems like inadequate food, care practices, or health environments.

Monitoring the adequacy of rations and promoting self-reliance and exit strategies are also covered.
Biochemical assessment PowerPoint, by sajib reza
Biochemical and functional tests can be used to assess nutritional status. Biochemical tests measure nutrients or their metabolites in biological samples like blood, urine, or tissues. They are useful for detecting later-stage deficiencies when body levels are depleted. Functional tests measure enzyme activities or physiological changes related to a nutrient. Both types of tests aim to be sensitive, specific, easy to perform, non-invasive, and inexpensive. Common biochemical tests include hemoglobin for iron status and serum retinol for vitamin A. Cut-off levels are used to define deficiencies for many nutrients based on biochemical indicators. Functional tests are less often used for large surveys due to invasiveness and difficulty interpreting results.

This document summarizes a study on the effect of risk perception on type 2 diabetes screening in a rural Thai village. The study found that:
1) The prevalence of type 2 diabetes was much higher in adults over age 45 (12.8%) than under age 45 (0.7%), and screening rates followed a similar pattern.
2) Less than half of residents were aware of the Ministry of Health's dietary recommendations. Risk perception emphasized genetic and age-related factors over behavioral factors like diet.
3) There may be an undiagnosed population of type 2 diabetes residents because of a misguided risk perception from a lack of nutritional knowledge, as screening participation was low among adults under 45.
FOODOMICS:A NEW APPROACH TO FOOD SAFETY AND PRODUCTION
Foodomics is a new discipline that applies omics technologies like genomics, transcriptomics, proteomics, and metabolomics to study food and nutrition.

Diet is a major lifestyle-related risk factor of various chronic diseases. Dietary intake can be assessed by sub-
jective report and objective observation. Subjective assessment is possible using open-ended surveys such as
dietary recalls or records, or using closed-ended surveys including food frequency questionnaires. Each meth-
od has inherent strengths and limitations. Continued efforts to improve the accuracy of dietary intake assess-
ment and enhance its feasibility in epidemiological studies have been made. This article reviews common di-
etary assessment methods and their feasibility in epidemiological studies.
KEY WORDS: Dietary assessment, Food frequency questionnaire, 24-hour dietary recall, Dietary record
INTRODUCTION
Diet is a major lifestyle-related risk factor of a wide range of
chronic diseases. Changes in dietary habits have been found to
reduce cancer incidence by one-third [1]. Dietary information
has been useful in cardiovascular disease risk prediction [2] and
consuming a nutrient-dense diet was associated with a low risk
of all-cause mortality [3]. Contrary to other lifestyle risk factors
(e.g., smoking), dietary exposures are very difficult to measure
because all individuals eat foods, even if the amount and the
kind of food consumed is various between subjects, and people
rarely perceive what they eat and how much they do [4]. Inac-
curate dietary assessment may be a serious obstacle of under-
standing the impact of dietary factors on disease.
Specific biochemical markers have been used as a surrogate
to measure the dietary intake of selected nutrients or dietary
components in epidemiological studies [5-7]. Previous studies
have found these markers to be highly correlated with dietary
intake levels, free of a social desirability bias, independent of
memory, and not based on subjects’ ability to describe the type
and quantity of food consumed [8]. Thus, these biochemical
markers may provide more accurate measures than dietary in-
take estimates do. However, a number of biomarkers have been

This document provides the vision and goals for a Joint Programming Initiative (JPI) on nutrition, diet, and health from 2010-2030. The goals are to significantly reduce the burden of diet-related diseases in Europe by 2030 by ensuring all Europeans have the motivation, ability, and opportunity to consume a healthy diet and be physically active. It outlines three key research areas: 1) determinants of diet and physical activity behavior, 2) the relationship between diet, food production, and health, and 3) preventing diet-related chronic diseases. The document argues that individual countries cannot adequately address these complex issues alone and a joint, coordinated research effort is needed.

Abstract
During the lifespan, there are multiple factors influence the longevity including genotype, metabolism, physiology, sociodemographic and environmental factors, nutritional and lifestyle habits. Nutrition during the life time has an effect on the health status. Dietary indexes, certain dietary patterns and dietary guidelines have been used for analysing dietary pattern and life expectancy relationship in many studies. Dietary pattern has an important effect on longevity. The cohort study results indicate that diet quality and Medittarenean diet have potential effects on longevity. The important effects of nutrition on longevity related with quality, quantity, frequency, variety and emotional satisfaction. Therefore, nutritional strategies that provide clear benefits for ageing linked with both physiological and psychological functions to maintain life quality. The aspiration is not only to “live longer” but to “live better,” and to maintain optimal qual¬ity of life during the later stages of life.La medicina di precisione: una sfida per l'SSN

UNIT II PUBLIC HEALTH NUTRITION.pptx
This document discusses the relationship between nutrition, health, and economic development. It states that malnutrition negatively impacts economic development by increasing mortality and morbidity, especially in children and women. Poor nutrition lowers educational performance and cognitive ability due to issues like iodine and iron deficiencies. However, improved nutrition can boost economic growth by increasing labor productivity and utilization of resources. Overall, better health and nutrition are closely tied to individual and national well-being and prosperity.
Nutrigenomics
This document discusses nutrigenomics, an emerging field that examines the relationship between nutrients and the human genome using modern "omics" technologies like transcriptomics, metabolomics, epigenomics, and proteomics. It provides an overview of nutrigenomics and related fields like nutrigenetics, describes some of the experimental approaches and technologies used in nutrigenomics research, and gives examples of specific research findings like how coffee and cigarettes may help combat rare liver diseases.
Hospital Based Prevalence of Malnutrition in Pediatrics
Hospital Based Prevalence of Malnutrition in PediatricsSSR Institute of International Journal of Life Sciences
ABSTRACT- Background: Malnutrition constitutes a major public health concern worldwide and serves as an indicator
of hospitalized patient’s prognosis. Nutritional support is an essential aspect of the clinical management of children
admitted to hospital. Malnutrition has been long associated with poor quality, poor diet and inadequate access to health
care, and it remains a key global health issue that both stems from and contributes to weakness, with 50% of childhood
deaths due to principal under nutrition.
Methods: The present hospital based cross sectional study was conducted in April to Dec 2015 among 300 rural
adolescents of 9-18 years age (146 boys and 154 girls) attending the outpatient department at Patna Medical College and
Hospital, Bihar, India, belonging to the all caste communities. The nutritional status was assessed in terms of under
nutrition (weight-for-age below 3rd percentile), stunting (Height-for-age below 3rd percentile) and thinness (BMI-for-age
below 5th percentile). Diseases were accepted as such as diagnosed by pediatrician, skin specialist and medical officer.
Results: The prevalence of underweight, stunting and thinness were found to be 31%, 22.3% and 30.7% respectively. The
maximum prevalence of malnutrition was observed among early adolescents (23% - 54%) and the most common
morbidities were diarrhoea (16.7%), carbuncle / furuncle (16.7%) and scabies (12%).
Conclusion: Malnutrition among hospitalized under five children and around suffers moderately high rates of
malnutrition. Present nutrition programs attention on education for at risk children and referral to regional hospitals for
malnourished children. Screening tools to classify children at risk of developing malnutrition might be helpful.

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
