Could Francis Collins’ Faith Create Conflicts For His Potential Directorship of NIH?

Francis Collins, M.D., Ph.D., is probably best known for his leadership of the Human Genome Project, though his discoveries of the Cystic Fibrosis, Huntington’s, and Neurofibromatosis genes are also extraordinary accomplishments. Dr. Collins is a world-renowned scientist and geneticist, and also a committed Christian. In his recent best-selling book, The Language Of God, Dr. Collins attempts to harmonize his commitment to both science and religion.

Some critics (such as Richard Dawkins) have expressed reservations about Dr. Collins’ faith, wondering if it might cloud his scientific judgment. Since Collins is rumored to be the most likely candidate for directorship of the NIH, and because I wanted to know if Dawkins et al. had any reason for concern, I decided to read The Language Of God.

First of all, Christians are a rather heterogeneous group – with a range of viewpoints on evolution, science, and the interpretation of Biblical texts. On one extreme there are Christians (often referred to as “young earth creationists” or simply “creationists”) who believe in an absolutely literal interpretation of the Genesis story, and see evolution as antithetical to true faith. Dr. Collins suggests that as many as 45% of Christians may actually be in this camp.

Human Subjects as Political Pawns

When it comes to “alternative medicine” trials, it seems that the NIH is willing to experiment on people in ways that would be unthinkable for real biomedical research. The federal Office for Human Research Protections (OHRP) has posted a preliminary determination letter, dated May 27, 2009, addressing some of the charges we had made against the politics-driven NIH Trial to Assess Chelation Therapy (TACT).

It is a remarkably damning statement, particularly regarding an NIH study. That is, it found—or the recipients admitted—that each of several charges was valid. Among these are misleading statements and unstated risks in the consent form, and the embarrassing backgrounds of TACT investigators. According to the determination letter,

…investigations revealed multiple instances of substandard practices, insurance fraud, and felony activity on the part of investigators.”

Chiropractic – A Brief Overview, Part II

Last week I reviewed the history of chiropractic and discussed issues relating to its underlying claims and treatments for non-musculoskeletal indications. Today I will focus on chiropractic for back pain and similar indications.

Manipulative Therapy

There is evidence to support the very narrow indication of spinal manipulation for the symptomatic management of acute uncomplicated lower back strain. The good news for chiropractors is that this is a very common condition and does not respond well to conventional management – actually all treatments: medical management, physical therapy, manipulation, and even just patient education, appear to be equally and quite modestly effective.

There is a body of clinical studies that are relevant to the question of manipulation for lower back strain. A review of this research was published in 1989 by the RAND corporation, an independent research group that put together a panel of both physicians and chiropractors to review the available research on manipulative therapy. They concluded that evidence from 22 studies supported the use of manipulative therapy for acute uncomplicated lower back pain (again – no real pinched nerves). It is important to understand, however, that they were referring to manipulative therapy, not chiropractic. In fact only 4 of the 22 studies mentioned included chiropractors. In the other studies the manipulative therapy was performed by physicians and physical therapists.
