Pneumocystis carinii mutations associated with sulfa and sulfone prophylaxis failures in AIDS patients

Background:Failures of prophylaxis against Pneumocystis carinii pneumonia (PCP) in AIDS patients do occur, but no evidence for drug resistance has yet been presented. Objective:To determine whether mutations in the sulfa and sulfone drug target are associated with failure of prophylaxis using a sulfa-containing agent. Methods:Portions of the gene for P. carinii dihydropteroate synthase (DHPS), the sulfa and sulfone target, from 27 patients (20 of whom had AIDS) diagnosed with PCP between 1976 and 1997 were amplified using polymerase chain reaction and sequenced. Seven of the 27 patients (all of whom had AIDS) were receiving sulfa or sulfone drugs as prophylaxis for PCP. Results:Mutations were found at only two amino-acid positions and were significantly more common in patients who received sulfa/sulfone prophylaxis. Mutations were observed in five (71%) out of seven isolates from AIDS patients receiving sulfa/sulfone as prophylaxis compared with only two (15%) out of 13 specimens from AIDS patients who did not (P = 0.022). No mutations were seen in isolates from seven non-HIV-infected patients, none of whom were on prophylaxis. Mutations were only observed in specimens obtained in 1995–1997. Conclusions:Mutations in two amino-acid positions were significantly more common in AIDS patients with PCP who failed sulfa/sulfone prophylaxis. These amino acids appeared to be directly involved in both substrate and sulfa binding, based on homology to the Escherichia coli DHPS crystal structure. Thus, the results were consistent with the possibility that mutations in the P. carinii DHPS are responsible for some of the failures of sulfa/sulfone prophylaxis in AIDS patients.

Developing and implementing core competencies for integrative medicine fellowships

The Consortium of Academic Health Centers for Integrative Medicine defines integrative medicine as “the practice of medicine that reaffirms the importance of the relationship between practitioner and patient, focuses on the whole person, is informed by evidence, and makes use of all appropriate therapeutic approaches, health care professionals, and disciplines to achieve optimal health and healing.” Over the past three decades, the U.S. public increasingly has sought integrative medicine approaches. In an effort to train medical professionals to adequately counsel patients on the safe and appropriate use of these approaches, medical schools and residencies have developed curricula on integrative medicine for their trainees. In addition, integrative medicine clinical fellowships for postresidency physicians have emerged to provide training for practitioners interested in gaining greater expertise in this emerging field. Currently, 13 clinical fellowships in integrative medicine exist in the United States, and they are predominantly connected to academic medical centers or teaching affiliate hospitals. In 2010, the Consortium of Academic Health Centers for Integrative Medicine, represented by 56 member academic health care institutions with a shared commitment to advance the principles and practices of integrative medicine, convened a two-year task force to draft integrative medicine fellowship core competencies. These competencies would guide fellowship curriculum development and ensure that graduates possessed a common body of knowledge, skills, and attitudes. In this article, the authors discuss the competencies and the task force’s process to develop them, as well as associated teaching and assessment methods, faculty development, potential barriers, and future directions.

RECOMMENDED INTEGRATIVE MEDICINE COMPETENCIES FOR FAMILY MEDICINE RESIDENTS

BACKGROUND The use of complementary and alternative medicine (CAM) and Integrative Medicine (IM) has grown steadily over the past decade. Patients seek physician guidance, yet physicians typically have limited knowledge and training. There is some coverage of IM/CAM topics in medical schools and residencies but with little coordination or consistency. METHODOLOGY In 2008, the Society of Teachers of Family Medicine (STFM) group on Integrative Medicine began the process of designing a set of competencies to educate Family Medicine residents in core concepts of IM. The goal was creation of a set of nationally recognized competencies tied to the Accreditation Council for Graduate Medical Education (ACGME) domains. These competencies were to be achievable by diverse programs, including those without significant internal resources. The group compiled existing curricula from programs around the country and distilled these competencies through multiple reviews and discussions. Simultaneously, the Integrative Medicine in Residency program run by the University of Arizona underwent a similar process. In 2009, these competencies were combined and further developed at the STFM annual meeting by a group of experts. RESULTS In 2010, the STFM Board approved 19 measurable competencies, each categorized by ACGME domain, as recommended for Family Medicine residencies. Programs have implemented these competencies in various ways given individual needs and resources. CONCLUSIONS This paper reviews the development of IM competencies for residency education in Family Medicine and presents those endorsed by STFM. By educating physicians in training about IM/CAM via competency-based curricula, we aim to promote comprehensive patient-centered care.

Delivery of Health Coaching by Medical Assistants in Primary Care

Background: Health coaching is potentially a practical method to assist patients in achieving and maintaining healthy lifestyles. In health coaching, the coach partners with the patient, helping patients discover their own strengths, challenges, and solutions. Methods: Two medical assistants were provided with brief training. The 12-week program consisted of telephone coaching with in-person visits at the beginning and end of the program. Coaching targeted improvements in diet, physical activity, and/or sleep habits using a self-care planning form. Results: A total of 82 subjects enrolled in the program, 72% completed 8 weeks and 49% completed 12 weeks. Subjects who completed assessments at 12 weeks had significant weight loss despite the fact that weight loss was not a study goal. There also were improvements in diet and physical activity. Subject who completed the study were highly satisfied with the program and felt that health coaching should be available in all family medicine clinics. The main barrier providers voiced was remembering to refer patients. The medical providers indicated high satisfaction with the study and valued having coaching available for their patients. Conclusions: Medical assistants can be trained to assist patients with lifestyle changes that are associated with improved health and weight control.

Integrative Women’s Health

This article addresses the common womens health concerns of menopause-related symptoms, premenstrual syndrome, and chronic pelvic pain. Each can be effectively addressed with an integrative approach that incorporates interventions such as pharmaceuticals, nutraceuticals, mind-body approaches, acupuncture, and lifestyle modification.
