# 9th lect clinical trial analysis
The document discusses key concepts in analyzing clinical trials, including:
- Intention-to-treat analysis, which analyzes all participants based on initial treatment assignment regardless of compliance, and measures effectiveness. This is the recommended primary analysis method.
- Per-protocol analysis, which only includes compliant participants, and measures maximum efficacy. This undermines randomization.
- Measures of effect size such as relative risk, absolute risk reduction, relative risk reduction, and number needed to treat, which are used to assess clinical significance beyond just statistical significance.
- The importance of assessing both statistical and clinical significance of trial results, where clinical significance considers the minimum clinically meaningful effect.
# 8th lect validity threats
Dr. Eman M. Mortada discusses threats to validity in experimental designs, including internal validity threats such as history, maturation, testing, instrumentation, and mortality. External validity threats include reactive arrangements like the Hawthorne effect and experimenter effects such as the halo effect. Control validity threats involve factors that could influence the dependent variable other than the independent variable, such as selection bias, statistical regression, and diffusion of treatment. Randomization, control groups, and blinding techniques can help address threats to validity. True experiments have higher internal but lower external validity compared to quasi-experimental designs.
# 7th lect quasi experimental research designs
This document provides an overview of experimental research designs, including pre-experimental, true experimental, and quasi-experimental designs. It discusses key elements like independent and dependent variables, experimental and control groups, and pretesting and posttesting. Specific designs covered include the one-shot case study, one-group pretest-posttest, static group comparison, posttest-only control group, pretest-posttest control group, and Solomon four-group designs. The document emphasizes random assignment and control groups as critical features of true experiments that enhance internal and external validity.
# 6th lect structure of the trials
Types of clinical trials designs were discussed including parallel designs, crossover designs, factorial designs, cluster designs, and adaptive designs. The key factors in choosing a clinical trial design are treatment duration and chronology of events, trial cost, and subject convenience. Commonly used designs include parallel, crossover, factorial, and equivalence/non-inferiority designs. The randomized, double-blind, placebo-controlled, parallel design is often considered the best to determine efficacy. Different designs can answer different therapeutic questions.
# 5th lect clinical trial process
This document outlines the key steps in conducting a clinical trial:
1. Drawing up a detailed research protocol that serves as the trial's operating manual.
2. Selecting and screening participants according to eligibility criteria to identify the study population. Sample size is also calculated.
3. Randomly allocating the study participants into experimental and control groups through a process like randomization to reduce bias.
# 4th lect HSR
This study compares two ice cream eating regimens - accelerated versus cautious eating - and their effects on headaches. Participants will be randomly assigned to quickly eat 100ml of ice cream in under 30 seconds or slowly eat it over 5 minutes. The study aims to determine if the speed of ice cream consumption impacts headache occurrence. This level of review would likely be expedited due to minimal risk to participants.
# 3rd lect research ethics
Dr. Eman Mortada discusses research ethics and provides an outline on the topic. The document outlines key concepts such as defining research ethics, the consequences of scientific misconduct, and the need and objectives for research ethics. It also provides a historical perspective on unethical practices through examples like the Tuskegee Syphilis Study and Nazi experiments. The development of ethics codes is reviewed, including the Nuremberg Code, Declaration of Helsinki, and Belmont Report. Ethical principles and dilemmas in research are also discussed.
# 2nd lect phases and types of the intervention research
Dr. Eman Mortada's lecture discusses the history and phases of clinical trials. It begins with early examples of clinical trials like James Lind's experiments in 1747 and Edward Jenner's smallpox vaccination trials in the late 18th century. It then covers the four phases of modern clinical drug trials - phase I tests safety on healthy volunteers, phase II assesses efficacy on patients, phase III tests larger groups for efficacy and safety, and phase IV monitors effectiveness and side effects post-approval. The lecture also discusses types of clinical trials based on the unit of study and ethics considerations around clinical equipoise.

3rd lecture- Sociological perspectives and their applications on health 2020
The document discusses sociological perspectives on health and illness from three major theoretical perspectives: functionalism, conflict theory, and symbolic interactionism. According to the functionalist perspective, health is important for society's stability as illness prevents people from fulfilling their social roles. The sick role concept developed by Talcott Parsons outlines the rights and obligations of those who are ill in a society. Conflict theory views health inequalities in terms of power struggles around factors like race, class, and gender. Symbolic interactionism focuses on how health, illness, and medicine are socially constructed and mediated by communication and symbols.
2 social structure
Societies transition from preindustrial to industrial based on changes in technology and food production. In preindustrial societies, people lived in small, close-knit communities and relied on hunting/gathering, pastoralism, horticulture or agriculture. The industrial revolution led to mechanization of production and urbanization as people moved to cities to work in factories. This marked the shift to industrial societies with specialized roles, weaker community ties, and more competition.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
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.Hemodialysis: Chapter 4, Dialysate Circuit - Dr.Gawad
