BACKGROUND. Food allergy (FA) is a growing health problem requiring physiologic confirmation via the oral food challenge (OFC). Many OFCs result in clinical anaphylaxis, causing discomfort and risk while limiting OFC utility. Transepidermal water loss (TEWL) measurement provides a potential solution to detect food anaphylaxis in real time prior to clinical symptoms. We evaluated whether TEWL changes during an OFC could predict anaphylaxis onset. METHODS. Physicians and nurses blinded to the TEWL results conducted and adjudicated the results of all 209 OFCs in this study. A study coordinator measured TEWL throughout the OFC and had no input on the OFC conduct. TEWL was measured 2 ways in 2 separate groups. First, TEWL was measured using static, discrete measurements. Second, TEWL was measured using continuous monitoring. Participants who consented provided blood samples before and after the OFCs for biomarker analyses. RESULTS. TEWL rose significantly (2.93 g/m²/h) during reactions and did not rise during nonreacting OFCs (–1.00 g/m²/h). Systemic increases in tryptase and IL-3 were also detected during reactions, providing supporting biochemical evidence of anaphylaxis. The TEWL rise occurred 48 minutes earlier than clinically evident anaphylaxis. Continuous monitoring detected a significant rise in TEWL that presaged positive OFCs, but no rise was seen in the OFCs that resulted in no reaction, providing high predictive specificity (96%) for anaphylaxis against nonreactions 38 minutes prior to anaphylaxis onset. CONCLUSIONS. During OFCs, a TEWL rise anticipated a positive clinical challenge. TEWL presents a monitoring modality that may predict food anaphylaxis and facilitate improvements in OFC safety and tolerability. [ABSTRACT FROM AUTHOR]

Objective: African American women are disproportionately burdened by asthma morbidity and mortality and may be more likely than asthma patients in general to have comorbid health conditions. This study sought to identify the self-management challenges faced by African American women with asthma and comorbidities, how they prioritize their conditions and behaviors perceived as beneficial across conditions. Methods: In-depth interviews were conducted with 25 African-American women (mean age 52 years) with persistent asthma and at least one of the following: diabetes, heart disease or arthritis. Information was elicited on women's experiences managing asthma and concurrent health conditions. The constant-comparison analytic method was used to develop and apply a coding scheme to interview transcripts. Key themes and subthemes were identified. Results: Participants reported an average of 5.7 comorbidities. Fewer than half of the sample considered asthma their main health problem; these perceptions were influenced by beliefs about the relative controllability, predictability and severity of their health conditions. Participants reported ways in which comorbidities affected asthma management, including that asthma sometimes took a 'backseat' to conditions considered more troublesome or worrisome. Mood problems, sometimes attributed to pain or functional limitations resulting from comorbidities, reduced motivation for self-management. Women described how asthma affected comorbidity management; e.g. by impeding recommended exercise. Some self-management recommendations, such as physical activity and weight control, were seen as beneficial across conditions. Conclusions: Multiple chronic conditions that include asthma may interact to complicate self-management of each condition. Additional clinical attention and self-management support may help to reduce multimorbidity-related challenges. [ABSTRACT FROM AUTHOR]

The article presents a study on the link between having an asthma action plan (AAP) and behaviors to keep asthma in control and patient satisfaction among women with asthma. Women without an AAP were found to be less likely to take asthma medication as prescribed, less likely to initiate discussion about asthma with their physicians, and less likely to own a peak flow meter. The lack of AAP may reportedly affect interactions between patient and physician and may affect clinical outcomes.

Objective. To examine characteristics of women with negotiated treatment plans, factors that contribute to newly forming a treatment plan, and the impact of plans on asthma management, and their satisfaction with care over 2 years. Methods. Data came from telephone interviews with 324 women with asthma at baseline, 12 and 24 months. The effect of having a negotiated treatment plan on medication adherence, asking the physician questions about asthma, asthma management self-efficacy, and satisfaction with care was assessed over 24 months. Data were analyzed using mixed models. Analyses controlled for patient characteristics. Results. Thirty-eight percent of participants reported having a negotiated treatment plan at three time points. Seeing an asthma specialist (χ2(1) = 24.07, p < .001), was associated with having a plan. Women who did not have a negotiated treatment plan at baseline, but acquired one at 12 or 24 months, were more likely to report greater urgent office visits for asthma (odds ratio (OR) = 1.37, 95% confidence interval (CI) = 1.07-1.61). No associations were observed between having a plan and urgent healthcare use or symptom frequency. When adjusting for household income, level of asthma control, and specialty of the caregiving provider, women who did not have a negotiated treatment plan (OR = 0.28, 95% CI = 0.09-0.79) and those with a plan at fewer than three time points (OR = 0.30, 95% CI = 0.11-0.83) were less likely to report medication adherence and satisfaction with their care (regression coefficient (standard error) = -0.65 (0.17), p < .001). No differences in asthma management self-efficacy or asking the doctor questions about asthma were observed. Conclusion. Women with asthma who had a negotiated treatment plan were more likely to see an asthma specialist. In the long-term, not having a treatment plan that is developed in partnership with a clinician may have an adverse impact on medication use and patient views of clinical services.

Background. Electronic media such as social media (Facebook, Twitter, MySpace), email, and text messaging could be useful in the management of asthma. However, patient use and preferences for electronic media in asthma management is currently unknown. Methods. A survey was sent to asthma patients between 12-40 years of age. The survey collected demographic information, use of electronic media, interest in using electronic media to receive asthma information, and interest in using electronic media to communicate with a health care provider about asthma. Free text entries were encouraged. Results. 145 completed surveys were returned. Text messaging, email, and Facebook were used at least weekly by a majority of respondents (82%, 77%, and 65%, respectively). Email was clearly the most preferred method to receive asthma information and to communicate with a physician. There was some interest in using Facebook or text messaging, whereas Myspace and Twitter had minimal interest. On logistic regression analysis, female and Black or Hispanic participants were more likely to have an interest in the use of electronic media for asthma care. Frequent users (>1X//week) of each electronic media type had greater enthusiasm for their incorporation into asthma care. Free text entries revealed that many participants felt social media sites were for connecting with friends rather than for health care, and privacy concerns were also raised. Conclusion. Electronic media offers a novel way to improve asthma care. Email was the most preferred method, though text messaging and social media sites like Facebook may be appropriate for certain patients.

Symptoms of esophageal dysfunction such as food impaction are consistent with, but not diagnostic for eosinophilic esophagitis (EoE) without obtaining histology. We conducted a retrospective study to characterize patients with food impaction at a tertiary center. We hypothesized that many patients with food impaction may be lost to follow-up and that many have features suggestive of EoE. Adult patients presenting to the emergency department with esophageal food impaction were identified from an endoscopic database. Electronic medical records were manually abstracted. We examined associations between demographics, comorbid conditions, and follow-up with biopsy findings. Of 220 patients who presented to the emergency department for food impaction, 74.1% were men. Adequate follow-up was not documented in 120 (54.5%). Those lost to follow-up did not differ significantly by gender, age at symptom onset, or distance from hospital compared to those with follow-up. Esophageal biopsies were obtained in 158 (71.8%), and those with ≥15 eos/HPF were more likely to be lost to follow-up than those with <15 eos/HPF (52.8% vs. 34.8%, P < 0.05). Of those never biopsied, 79.0% were lost to follow-up and had intermediate proportions of males, food allergy, and asthma when compared to those with and without eosinophilic inflammation. Patients with food impaction commonly have EoE but are often lost to follow-up. Among those never biopsied, demographic and clinical features suggest that many may have undiagnosed EoE. Strategies for increasing use of biopsies in patients with food impaction and improving follow-up are needed to diagnose and manage EoE. [ABSTRACT FROM AUTHOR]
