An observational study is one in which outcomes are assessed without the researcher being involved.

<h3>What does an observational research aim to accomplish?</h3>

In observational studies, subjects are observed without having their conditions forcibly altered, or in other words, without any intervention. Although participants' behavior may change while being observed, observational studies aim to look at risk factors, diseases, or outcomes in their "natural" form.

<h3>What are an observational study's advantages?</h3>

The primary benefit of observational research has already been mentioned: it gives companies the chance to observe prospective clients in their natural environment, which can provide illuminating information that cannot be obtained through other techniques like focus groups and questionnaires.

Diseases in the present age are very different from diseases of the past discuss ​
PolarNik [594]

Answer:

Control and prevention measures had decreased the incidence of many infectious diseases, and with the ability to continue to identify new antibiotics, to handle new problems, and the ongoing development of appropriate vaccines, his statement appeared to be appropriate.

In the US, similar feelings were expressed and funding for infectious disease fellowships began to decline with federal resources being directed elsewhere.

The history of the world is intertwined with the impact that infectious diseases have had on populations. Evidence of smallpox has been found in 3000-year-old Egyptian mummies. Egyptian papyrus paintings depict infectious diseases such as poliomyelitis. Hippocrates wrote about the spread of disease by means of airs, water, and places, and made an association between climate, diet, and living conditions. Investigators described miasmas as the source of infections. Fracastoro discussed the germ theory in the 1500s and three routes of contagion were proposed—direct contact, fomites, and contagion from a distance (airborne). Epidemics of leprosy, plague, syphilis, smallpox, cholera, yellow fever, typhoid fever, and other infectious diseases were the norm.

The development of the microscope by Leeuwenhoek in the 1600s allowed scientists to visualize micro-organisms for the first time. The 1800s brought knowledge of the cultivation and identification of micro-organisms. Vaccines were developed and used which introduced specific methods to our storehouse of measures for control and prevention. Pasteurization was another important contribution to disease control. An appreciation of the environment and its relationship to infectious diseases resulted in implementation of broad control measures such as community sanitation, personal hygiene, and public health education. The importance of nutrition was appreciated for its impact on infectious diseases.

The 20th century brought chemotherapy and antibiotics into our infectious disease armamentarium. Greater dependency upon vaccination programmes and health education became important allies in our efforts at reducing the occurrence of infectious disease. So Sir McFarland’s statement was not an off hand remark.

But we are now aware that emerging and re-emerging infections have become a significant worldwide problem. In 1991, the Institute of Medicine of the National Research Council in the US appointed a 19-member multidisciplinary expert committee to study the emergence of microbial threats to health. Their report published in 1992 was entitled, ‘Emerging Infections —Microbial Threats to Health in the United States’ but the concepts that they discussed certainly have worldwide application.1 They concluded that six categories of factors could explain the emergence or re-emergence of infectious diseases. These factors are: Human demographics and behaviour; Technology and industry; Economic development and land use; International travel and commerce; Microbial adaptation and change; and Breakdown of public health measures.

________ involves controlled breathing while assuming certain body positions and minimizing external stimuli. Hypnosis Meditatio
lana66690 [7]

Answer:

The best answer is letter B. meditation.

Explanation:

Meditation as a practice to focus one's attention involves what is described in the question - controlled breathing, assuming certain body positions, minimizing external stimuli. Mindfulness meditation, for instance, has the person focus on their breathing while effortlessly observing his/her thoughts without allowing those thoughts to take over.

We can safely eliminate the other options. Hypnosis is a state of high focus and concentration, but it is induced and makes the person more responsive to suggestion. Consciousness has several definitions, but can be summarized as the awareness of one's own internal and external existence. Dichotic listening happens when a person listens to a type of sound through one ear and another type of sound through the other, simultaneously. Cataplexy is the loss of muscle tone caused by strong emotions.
