Acupuncture gained mainstream appeal in the United States primarily in the 1970s. Therefore, option (A) is correct.
Acupuncture gained more recognition and appeal as a therapeutic practise during this period as interest in complementary and alternative medicine developed. The National Acupuncture Association, which was established in the early 1970s and eventually changed its name to the American Association of Acupuncture, and the release of significant acupuncture literature both helped to its acceptance and reputation.
In addition, in 1972, extensive media coverage and public interest in acupuncture's potential advantages were sparked by a New York Times journalist's personal encounter with the treatment while he was visiting China. The development of acupuncture institutions, its incorporation in medical curriculum, and the emergence of specialised acupuncture organisations during the next decades furthered acupuncture's integration into mainstream healthcare.

long-term use of opioid drugs has been clearly shown to damage both the liver and the brain. (True or False)
The statement "long-term use of opioid drugs has been clearly shown to damage both the liver and the brain" is false.
Long-term use of opioid drugs can have adverse effects on both the liver and the brain, but it is not accurate to say that it has been clearly shown to damage both organs in all cases. Opioid medications, when used as prescribed and under medical supervision, can be safe and effective for managing pain. However, misuse, abuse, or prolonged use of opioids can lead to various health complications.
In terms of the liver, chronic opioid use can potentially contribute to conditions such as opioid-induced liver injury, hepatitis, or liver fibrosis in some individuals. However, the extent and severity of liver damage can vary among individuals based on factors such as the dosage, duration of use, individual susceptibility, and co-existing liver conditions.
Regarding the brain, opioid drugs primarily act on opioid receptors in the central nervous system. Prolonged opioid use can lead to neuroadaptive changes, tolerance, and dependence. It may also increase the risk of mental health issues, such as depression or anxiety. However, not everyone who uses opioids will experience severe brain damage.
It's important to note that the effects of opioids on the liver and brain can vary from person to person, and the extent of damage depends on multiple factors. Regular monitoring, appropriate medical supervision, and responsible use of opioid medications can help mitigate potential risks.

An investigator finds a positive correlation between per capita alcohol consumption and mortality rates for breast cancer across 20 different countries. In order to investigate this relationship further, the investigators conduct a study selecting 200 women with breast cancer and comparing them with 200 women without breast cancer. The women are compared with respect to earlier drinking habits. If women with breast cancer are more likely than women without breast cancer to overestimate prior alcohol consumption, the apparent association between drinking and risk of breast cancer will be?
a. Increased
b. Decreased
c. Unchanged
d Altered but the direction cannot be predicted
The apparent association between drinking and risk of breast cancer will be: b. Decreased. The correct option is b.
If women with breast cancer are more likely than women without breast cancer to overestimate prior alcohol consumption, then the observed association between drinking and risk of breast cancer will be weakened or decreased. This is because the apparent correlation between alcohol consumption and breast cancer risk would be biased by measurement error in the self-reported drinking data.
The overestimation of prior alcohol consumption by women with breast cancer will lead to an exaggeration of the association between drinking and breast cancer risk, as compared to women without breast cancer who may report their drinking habits more accurately. This type of measurement error is known as recall bias and is a common issue in retrospective studies relying on self-reported data.

what system helps to integrate innate and adaptive immune responses? group of answer choices pamps cytokines complement interferon
The system that helps to integrate innate and adaptive immune responses is the cytokines.
Cytokines are small proteins secreted by various cells of the immune system, including macrophages, dendritic cells, and T cells. They serve as important mediators and communicators between the innate and adaptive immune responses, helping to coordinate and regulate the overall immune response.
During an immune response, innate immune cells recognize pathogens through pattern recognition receptors (PRRs), which detect specific molecules called pathogen-associated molecular patterns (PAMPs) present on pathogens. Once PAMPs are recognized, innate immune cells produce and release cytokines.
Cytokines act as signaling molecules that communicate with other immune cells, including those of the adaptive immune system. They help to activate and recruit specific adaptive immune cells, such as T cells and B cells, to the site of infection or inflammation.
Cytokines also play a crucial role in shaping the adaptive immune response. They can promote the maturation and activation of antigen-presenting cells (such as dendritic cells) to effectively present antigens to T cells.

A 22-year-old female patient is complaining of dyspnea and numbness and tingling in her hands and feet after an argument with her fiancé. Her respirations are 40 breaths/min. You should:
A. have her breathe into a paper or plastic bag.
B. provide reassurance and give oxygen as needed.
C. request a paramedic to give her a sedative.
D. position her on her left side and transport at once
If a 22-year-old female patient is experiencing difficulty breathing and sensations of numbness and tingling in her hands and feet during an argument and she is breathing at a rate of 40 breaths per minute then the most appropriate action in this scenario would be: (B) Provide reassurance and give oxygen as needed.
The patient's symptoms, including dyspnea (shortness of breath) and numbness and tingling in her hands and feet, suggest signs of anxiety or hyperventilation syndrome. Hyperventilation can occur during times of stress or emotional distress and can lead to respiratory alkalosis, causing symptoms such as tingling and numbness in the extremities. Providing reassurance to the patient and administering oxygen, if needed, can help alleviate her symptoms and restore normal breathing patterns.
Option A (having her breathe into a paper or plastic bag) is not recommended as it can potentially worsen the situation and lead to rebreathing of carbon dioxide, which may be harmful.
Option C (requesting a paramedic to give her a sedative) is not necessary at this point, as the patient's symptoms can be managed through reassurance and supportive care.
Option D (positioning her on her left side and transport at once) is not indicated as there are no immediate life-threatening conditions present.
