One government source regarding clinical trials is Clinicaltrials.gov (https://clinicaltrials.gov), which is available to health information seekers as a resource to find information about past, current, and recruiting clinical trials. Currently, if you participate in a clinical trial you are required to provide your “informed consent.” This means you have been informed of the risks, benefits, purpose of the study, and your rights. This information is provided to you so that you, as the potential participant, can make an informed decision before deciding whether or not to participate. If you work with or in research, you will become very familiar with the term IRB, which stands for “Institutional Review Board.” An IRB is a panel intended to oversee the entire scope of one or more medical research studies including protecting the rights and welfare of human research subjects. Although it may seem like common sense that these two things are necessary, there was a time when they did not exist. A new approach to bioethics and the regulation of clinical trials and medical studies using living human subjects came about from public and governmental outrage over one study, known as the Tuskegee Syphilis Study. By looking specifically at this case, which led to the rise of bioethics at the federal-government level in the 1970s, the origin of IRBs and informed consent as they relate to medical studies and human subjects will be illuminated. The issues of IRBs, informed consent, and bioethics are important in the library and information science community because we often interact with a public that is impacted by the policies and regulations related to these issues. In addition, we are the very researchers, or hold relationships with researchers, that are held to the strict standards set in place by IRBs and bioethics in general.

The virtually complete loss of intestinal worms, known as helminths, from Western society has resulted in elimination of a range of helminth-induced morbidities. Unfortunately, that loss has also led to inflammation-associated deficiencies in immune function, ultimately contributing to widespread pandemics of allergies, autoimmunity, and neuropsychiatric disorders. Several socio-medical studies have examined the effects of intentional reworming, or self-treatment with helminths, on a variety of inflammation-related disorders. In this study, the latest results from ongoing socio-medical studies are described. The results point toward two important factors that appear to be overlooked in some if not most clinical trials. Specifically, (a) the method of preparation of the helminth can have a profound effect on its therapeutic efficacy, and (b) variation between individuals in the effective therapeutic dosage apparently covers a 10-fold range, regardless of the helminth used. These results highlight current limits in our understanding of the biology of both hosts and helminths, and suggest that information from self-treatment may be critical in moving the field forward into mainstream medicine.

The radionuclide gallium-67 (67Ga) localizes preferentially but not specifically in many human and experimental soft-tissue tumors. Because of this localization, 67Ga is used in clinical trials to detect humar. cancers by external scintiscanning methods. However, the fact that 67Ga does not localize specifically in tumors requires for its eventual clinical usefulness a fuller understanding of the mechanisms that control its deposition in both malignant and normal cells. We have previously reported that 67Ga localizes in lysosomal-like bodies, notably, although not exclusively, in macrophages of the spocytaneous AKR thymoma. Further studies on the uptake of 67Ga by macrophages are needed to determine whether there are factors related to malignancy that might alter the localization of 67Ga in these cells and thus provide clues to discovering the mechanism of 67Ga localization in tumor tissue.
