An epidemiologic study of postmenopausal women is performed. The subjects undergo periodic examination by dualenergy x-ray absor

ptiometry (DEXA) scan performed on the hip and lumbar vertebrae to evaluate bone mineral density over the next 10 years. They respond to a survey regarding their past and present use of drugs, diet, activity levels, history of bone fractures, and medical conditions. A subset of the subjects is identified whose bone mineral density is closest to that of the young adult reference range and in whom no bone fractures have occurred. The survey data from this subset of women are analyzed. Which of the following strategies is most likely to be supported by the study data to provide the best overall long-term reduction in risk of fracture in postmenopausal women?
A. Supplement the diet with calcium and vitamin D after menopause
B. Begin estrogen replacement therapy after a fracture
C. Avoid corticosteroid therapy for any inflammatory condition
D. Increase bone mass with exercise during childhood and young adulthood
E. Limit alcohol use, and avoid use of tobacco

Answer:

D. Increase bone mass with exercise during childhood and young adulthood

Explanation:

After the survey, a subset of the subjects is identified whose bone mineral density is closest to that of the young adult reference range and in whom no bone fractures have occurred.

The strategy that is most likely to be supported by the study data to provide the best overall long-term reduction in risk of fracture in postmenopausal women will be Increase bone mass with exercise during childhood and young adulthood. This is the right answer because the conditions for long-term reduction in risk of fracture needs to be the same for older women who have reached menopause and young adults and the only option which is best suited for such condition is Option D.

Answer:

Gene-environment interactions.

Explanation:

In gene-environment interactions, the field of epigenetics looks beyond the genotype itself and studies how the same genotype can be expressed in different ways. Scientists studied how the same genotype can turn out to be very different phenotypes. Gene expression is most of the time influenced by the environment in ways that are not always obvious. As we see in this case, identical twins share the same genetic information, their genetic material is exactly the same, but even with identical genes, there can be an incredible amount of difference in how gene expression can turn out throughout each twin’s life, one with schizophrenia and one completely healthy mentally.

How do surgical wounds usually heal?
yaroslaw [1]

Primary intention-  wound healing with skin edges that are approximated, risk of infection is low, healing occurs quickly with minimal scar formation as long as infection and secondary breakdown is prevented (similar to a surgical wound)   Most common = Acute wounds; minimal tissue loss = surgical wounds and superficial partial thickness (abrasions/blisters)

Secondary Intention  This type of healing is in wounds with extensive tissue loss/infection & wounds in which the edges cannot be approximated (closed).  Would is left open and granulation tissue gradually fills in the deficit. Susceptible to infection. Wet to dry dressings. Ex: Pressure Ulcer  Associated w/ pathology = diabetes, ischemia, pressure damage in inflammation  (Neuropathic, arterial, venous, full thickness, chronic inflammation)  Require ongoing wound care - larger scares
