Trinucleotide repeat (TNR) expansions and deletions are associated with human neurodegenerative diseases and prostate cancer. Recent studies have pointed to a linkage between oxidative DNA damage, base excision repair (BER) and TNR expansion, which is demonstrated by the observation that DNA polymerase β (pol β) gap-filling synthesis acts in concert with alternate flap cleavage by flap endonuclease 1 (FEN1) to mediate CAG repeat expansions. In this study, we provide the first evidence that the repair of a DNA base lesion can also contribute to CAG repeat deletions that were initiated by the formation of hairpins on both the template and the damaged strand of a continuous run of (CAG)20 or (CAG)25 repeats. Most important, we found that pol β not only bypassed one part of the large template hairpin but also managed to pass through almost the entire length of small hairpin. The unique hairpin bypass of pol β resulted in large and small deletions in coordination with FEN1 alternate flap cleavage. Our results provide new insight into the role of BER in modulating genome stability that is associated with human diseases.
Objectives: To examine the experience of patients from a low-income, ethnically diverse medically underserved population receiving acupuncture for chronic pain. Design: Qualitative analysis using inductive thematic analysis of interviews with participants from an acupuncture trial. Settings/Location: Four community health centers in the Bronx, New York. Participants: Thirty-seven adults with chronic neck or back pain or osteoarthritis who participated in a previous acupuncture trial. Interventions: Up to 14 weekly acupuncture treatments. Outcome measures: Pain and quality of life were examined in the original trial; this study examines qualitative outcomes. Results: The themes grouped naturally into three domains of the acupuncture experience: the decisionmaking process, the treatment experience, and the effect of acupuncture on health. Regarding decisionmaking, important factors were a willingness to try something new even if you do not necessary ''believe'' in it or have specifically positive expectations; a sense that medications were not working for their pain, that they also caused significant adverse effects, and that natural strategies might be preferable; and a feeling of desperation. Cost and access were significant barriers to acupuncture treatment. Regarding the process of acupuncture, the open and personal communication with the acupuncturist was an important factor, as were the sense that the process of acupuncture related to a natural process of healing or correction within the body and that part of making acupuncture successful required being open to the power of the mind to generate a positive outcome. Regarding the effect of treatment, notable aspects were the deep sense of rest and relaxation participants reported during treatment as well as the benefit they experienced for conditions other than pain. Conclusions: The themes that emerged in this ethnically diverse, low-income population were very similar to those that have emerged over the past decade of qualitative research on the acupuncture experience in other patient populations.
Background:
Primary care providers (PCPs) are expected to help patients with obesity to lose weight through behavior change counseling and patient-centered use of available weight management resources. Yet, many PCPs face knowledge gaps and clinical time constraints that hinder their ability to successfully support patients’ weight loss. Fortunately, a small and growing number of physicians are now certified in obesity medicine through the American Board of Obesity Medicine (ABOM) and can provide personalized and effective obesity treatment to individual patients. Little is known, however, about how to extend the expertise of ABOM-certified physicians to support PCPs and their many patients with obesity.
Aim:
To develop and pilot test an innovative care model – the Weight Navigation Program (WNP) – to integrate ABOM-certified physicians into primary care settings and to enhance the delivery of personalized, effective obesity care.
Methods:
Quality improvement program with an embedded, 12-month, single-arm pilot study. Patients with obesity and ≥1 weight-related co-morbidity may be referred to the WNP by PCPs. All patients seen within the WNP during the first 12 months of clinical operations will be compared to a matched cohort of patients from another primary care site. We will recruit a subset of WNP patients (n = 30) to participate in a remote weight monitoring pilot program, which will include surveys at 0, 6, and 12 months, qualitative interviews at 0 and 6 months, and use of an electronic health record (EHR)-based text messaging program for remote weight monitoring.
Discussion:
Obesity is a complex chronic condition that requires evidence-based, personalized, and longitudinal care. To deliver such care in general practice, the WNP leverages the expertise of ABOM-certified physicians, health system and community weight management resources, and EHR-based population health management tools. The WNP is an innovative model with the potential to be implemented, scaled, and sustained in diverse primary care settings.
While increased MBM and self-care training for providers may facilitate the integration of MBM into primary care, systematic changes are needed to decrease time pressures on providers and incentivize patient wellness. Despite barriers, providers are using innovative strategies to provide mind-body primary care in diverse practice settings.
