What is cigarettes?

Cigarettes are a form of tobacco product consisting of tightly rolled dried and processed leaves of the tobacco plant that are rolled into thin paper for smoking. They are usually smoked in a manner similar to cigars, but typically contain a higher proportion of additives than cigars. Cigarettes have been in existence for centuries, and have become increasingly popular due to a variety of factors, such as their widespread availability, low cost and their ability to be smoked in a variety of locations. Cigarette smoking is highly addictive, and has been linked to numerous health issues, including cancer, heart disease and stroke. Quitting smoking is the most effective way to reduce the risks associated with smoking, and is the only way to completely eliminate the dangers of smoking.

Phenylketonuria (PKU) is a disorder of amino acid metabolism. Use the Internet to research PKU, and then write three to four paragraphs that explain PKU and describe its causes, symptoms, and treatment.

Answers

Phenylketonuria (PKU) is a rare genetic disorder that affects the metabolism of the amino acid phenylalanine. PKU is caused by a deficiency in the enzyme phenylalanine hydroxylase (PAH), which is responsible for converting phenylalanine to tyrosine. When this enzyme is deficient, phenylalanine accumulates in the blood and brain, leading to a variety of symptoms.

The most common symptoms of PKU include intellectual disability, behavioral problems, and a musty odor on the skin and breath. PKU can also cause skin rashes, eczema, and seizures. In severe cases, PKU can lead to brain damage and serious neurological problems. If left untreated, PKU can have serious and long-lasting effects on an individual's health and development.

The treatment for PKU is a strict diet that is low in phenylalanine. This diet is typically started as soon as possible after birth and must be continued throughout life. The diet may include a special formula that is low in phenylalanine, as well as certain foods that are also low in phenylalanine. In addition, PKU patients may also be prescribed with a phenylalanine-free amino acid supplement to ensure that they get enough essential amino acids.

The management of PKU requires close monitoring of blood phenylalanine levels, and regular check-ups with a dietitian, a doctor and a psychologist. With appropriate treatment, PKU can be effectively managed, and individuals with PKU can lead healthy and fulfilling lives. However, if PKU is not diagnosed and treated early, it can have serious consequences.

Lack of free healthcare pros and cons

Answers

Advantages of free healthcare

1. Decreased costs

It is argued that free medical care can significantly reduce the healthcare cost of the country. People don’t have to pay consulting fees to the physicians on every visit. They are on the government’s payroll and will receive a fixed monthly salary. Moreover, free healthcare may also bring down the administrative cost as the government will be the only buyer of prescription drugs and medical equipment. Therefore, prices will remain regulated and there is no room for multiple vendors giving different quotes.

A study conducted by the University of Massachusetts, as cited in Britannica, stated that a uniform healthcare system could reduce the nation’s costs by up to $1.8 trillion dollars over a period of ten years.

2. Better economy

When the citizens of a country are healthy, they will be more productive. Some advocates believe that free healthcare would positively impact the economy of a country.

3. Savior of lives

Not everyone can afford health insurance, nor do they have the resources to pay for expensive medical treatments out of their own pocket. This means that a lack of free healthcare consequently poses a threat to their lives.

The disadvantage of free healthcare

Healthcare is expensive and there will be free healthcare pros and cons. This means that a free-of-cost healthcare system would result in the country going beyond its debt ceiling. Alternatively, the government would fund free healthcare by collecting additional taxes from the public, which is not possible because the tax-paying ability of low-income groups would stay the same.

1. Free healthcare would be dealing with chronic diseases first

Chronic diseases result in lifestyle choices of individuals and approx. 90% of the health budget is spent on them. If the whole health system would be free, the tax shelf would be greater for every individual. Plus, you will be paying the healthcare tax for someone else’s treatment as well, which sounds unfair to some.

2. From free healthcare, the service quality can be compromised

Once the healthcare facilities get free for all, the number of patients would instantly spike. This means that the nurses and doctors will have to spend extra duty hours to treat as many patients as possible in a day. Eventually, the quality of healthcare service would reduce drastically.

3. Free healthcare will make people care less about their health

When financial coverage is provided to people, they mostly ignore their health. For instance, neglect the importance of eating healthy, staying fit, and taking proper precautions, and will adopt an unhealthy lifestyle that eventually harms them. And all of this because they know they won’t have to pay anything for their healthcare.

who was called nurse ?

The term "nurse" was derived from the Latin word "nutrire," which meant to suckle and referred to a wet-nurse; it was not until the late 16th century that it acquired its contemporary connotation of a person who cares for the sick. Most societies have generated a stream of nurses committed to religious duty since the beginning of humanity.

Some hospitals had libraries and training programmes, and doctors wrote publications about their medical and pharmaceutical research. Thus, in-patient medical care in the sense of what we now call a hospital was invented as a result of Christian kindness and Byzantine creativity. [12] The Chief Physician (archiatroi), professional nurses (hypourgoi), and orderlies were among the Byzantine hospital personnel (hyperetai). By the twelfth century, Constantinople had two well-organized hospitals staffed by both male and female doctors. Systematic treatment processes and specialist wards for specific disorders were available.

A prevalence survey conducted from January 1 through December 31, 2003, identified 1,000 cases of schizophrenia in a city of 2 million persons. The incidence rate of schizophrenia in this population is 5/100,000 persons each year. What percent of the 1,000 cases were newly diagnosed in 2003?

Answers

Answer:

Explanation:

Assuming that all of the 1,000 cases of schizophrenia had been diagnosed prior to 2003 and none of them had been diagnosed before 2003, then 0% of the 1,000 cases were newly diagnosed in 2003. However, if some of the cases had been diagnosed before 2003, then the percentage of newly diagnosed cases in 2003 would be lower than 100%. To calculate the exact percentage, we would need to know the number of newly diagnosed cases in 2003 and the total number of cases diagnosed in 2003.

what is the incidence of lung cancer attributable to smoking in the total population
and what is the proportion of the risk in the total population that is attributable to smoking.

Answers

Answer:

Explanation:

The incidence of lung cancer attributable to smoking in the total population is 4.05/1,000, which is calculated by multiplying the incidence of lung cancer among smokers (9/1,000) by the proportion of smokers in the population (45%).

The proportion of the risk in the total population that is attributable to smoking is (4.05/1,000) / (10/1,000) = 40.5%. This is calculated by dividing the incidence of lung cancer attributable to smoking (4.05/1,000) by the total incidence of lung cancer (10/1,000).

Summarize and reflect on the topics included sensory adaptation/habituation, color blindness, deafness, our senses, and perceptual illusions

Answers

The Summary of the terms are given below

Sensory adaptation, also known as habituation, is the process by which our brains adjust to constant or repetitive stimuli, making them less noticeable over time. This can be seen in things like getting used to a certain smell or sound.

Color blindness is a condition in which a person is unable to see certain colors, typically red and green, due to a genetic mutation in the eye's color receptors. Deafness is the inability to hear sound and can be caused by various factors such as genetics, disease, or injury.

Our senses, such as sight, smell, taste, touch, and hearing, allow us to perceive the world around us. However, our senses can also be deceived by perceptual illusions, which are visual or auditory experiences that differ from reality.

Perceptual illusions are caused by the way our brain interprets the information it receives from our senses. They can be caused by factors such as the context of the stimulus, past experiences, and expectations. Reflecting on these topics highlights the complexity of how we perceive the world around us and the limitations of our senses. It also emphasizes the importance of understanding and interpreting the information our senses provide us with care and attention.

What is the senses about?

Sensory adaptation is the process by which our senses adjust to a constant stimulus, resulting in a decrease in sensitivity to that stimulus. Habituation is the process by which our brains learn to ignore irrelevant stimuli in order to focus on more important information.

Color blindness is a genetic condition that affects a person's ability to perceive color. It is caused by a lack of one of the three types of color receptors in the eye. Deafness is a condition that affects a person's ability to hear. It can be caused by a variety of factors, including genetics, disease, and injury.

Therefore. Our senses are the tools we use to perceive the world around us. They include sight, hearing, taste, smell, and touch. Perceptual illusions are visual or auditory phenomena that deceive our senses, causing us to perceive something that is not actually there. Examples include optical illusions and auditory hallucinations.

In epidemiology, incidence is a metric used to determine the likelihood that a given medical condition will manifest in a population within a given time frame. It is better to express it as a percentage or a rate with a denominator, even though it is occasionally loosely expressed as the total number of new cases during a given time period.

The term "incidence" describes the emergence of new cases of illness or injury within a population over a predetermined time frame.

1. To investigate the association between ascariasis and hand wash investigators conducted a case-control study with 100 cases (100 children with stool-test Positive) and 100 controls (100 children Negative). Among Positives children, 50 gave a history of exposure (frequent hand washes). Among those Negatives, 25 gave a history of exposure to hand washes.

 For this study, calculate the odds ratio & interpret the result.

Answers

The odd ratio is 3 and 3 means that the odds of having ascariasis (a positive stool test) are 3 times higher in children with a history of exposure.

What is the odd ratio?

To calculate the odds ratio for this study, we need to use the following formula:

Odds Ratio (OR) = (a/c) / (b/d)

where:

a = number of cases with a history of exposure (frequent hand washes)

b = number of cases without a history of exposure (frequent hand washes)

c = number of controls with a history of exposure (frequent hand washes)

d = number of controls without a history of exposure (frequent hand washes)

a = 50 (number of cases with a history of exposure)

b = 50 (number of cases without a history of exposure)

c = 25 (number of controls with a history of exposure)

d = 75 (number of controls without a history of exposure)

So, OR = (50/25) / (50/75) = 3

An OR of 3 means that the odds of having ascariasis (a positive stool test) are 3 times higher in children with a history of exposure (frequent hand washes) compared to children without a history of exposure.

What are the 4 major government-sponsored healthcare programs and describe the populations each is intended to serve?

Answers

Medicare. Medicare ensures a universal right to health care for persons age 65 and older. Eligible populations and the range of benefits covered have gradually expanded. In 1972, individuals under age 65 with long-term disabilities or end-stage renal disease became eligible.



Medicaid. The Medicaid program first gave states the option to receive federal matching funding for providing health care services to low-income families, the blind, and individuals with disabilities. Coverage was gradually made mandatory for low-income pregnant women and infants, and later for children up to age 18.


Children’s Health Insurance Program. In 1997, the Children’s Health Insurance Program, or CHIP, was created as a public, state-administered program for children in low-income families that earn too much to qualify for Medicaid but that are unlikely to be able to afford private insurance. Today, the program covers 9.6 million children.5 In some states, it operates as an extension of Medicaid; in other states, it is a separate program.


Affordable Care Act. In 2010, the passage of the Patient Protection and Affordable Care Act, or ACA, represented the largest expansion to date of the government’s role in financing and regulating health care. Components of the law’s major coverage expansions, implemented in 2014, included:
requiring most Americans to obtain health insurance or pay a penalty (the penalty was later removed)
extending coverage for young people by allowing them to remain on their parents’ private plans until age 26
opening health insurance marketplaces, or exchanges, which offer premium subsidies to lower- and middle-income individuals
expanding Medicaid eligibility with the help of federal subsidies (in states that chose this option).

Role of government: The federal government’s responsibilities include:
setting legislation and national strategies
administering and paying for the Medicare program
cofunding and setting basic requirements and regulations for the Medicaid program
cofunding CHIP
funding health insurance for federal employees as well as active and past members of the military and their families
regulating pharmaceutical products and medical devices
running federal marketplaces for private health insurance
providing premium subsidies for private marketplace coverage.
