Deep inspirations modulate airway caliber and airway closure and their effects are impaired in asthma. The association between asthma and obesity raises the question whether the deep inspiration (DI) effect is also impaired in the latter condition. We assessed the DI effects in obese and nonobese nonasthmatics. Thirty-six subjects (17 obese, 19 nonobese) underwent routine methacholine (Mch) challenge and 30 of them also had a modified bronchoprovocation in the absence of DIs. Lung function was monitored with spirometry and forced oscillation (FO) [resistance (R) at 5 Hz (R5), at 20 Hz (R20), R5-R20 and the integrated area of low-frequency reactance (AX)]. The response to Mch, assessed with area under the dose-response curves (AUC), was consistently greater in the routine challenge in the obese (mean ± SE, obese vs. nonobese AUC: R5: 15.7 ± 2.3 vs. 2.4 ± 2.0, P < 0.0005; R20: 5.6 ± 1.4 vs. 1.4 ± 1.2, P = 0.027; R5-R20: 10.2 ± 1.6 vs. 0.9 ± 0.1.4, P < 0.0005; AX: 115.6 ± 22.0 vs. 1.5 ± 18.9, P < 0.0005), but differences between groups in the modified challenge were smaller, indicating reduced DI effects in obesity. Given that DI has bronchodilatory and bronchoprotective effects, we further assessed these components separately. In the obese subjects, DI prior to Mch enhanced Mch-induced bronchoconstriction, but DI after Mch resulted in bronchodilation that was of similar magnitude as in the nonobese. We conclude that obesity is characterized by increased Mch responsiveness, predominantly of the small airways, due to a DI effect that renders the airways more sensitive to the stimulus.

Purpose: Current medical training recommends obtaining cervical cytological specimens without the use of lubricating gel. The purpose of this study was to determine whether water-soluble lubricant gel affects cytologic outcomes in the screening Papanicolaou smear and patient comfort during vaginal speculum examination.Methods: The study was a randomized controlled trial performed at David Grant US Air Force Medical Center (Travis Air Force Base, CA). Participants were female patients at least 18 years old presenting for an annual Papanicolaou smear. Each patient, blinded to group assignment, consented to two consecutive Papanicolaou smears. The first Papanicolaou smear was performed without gel in all subjects as part of the "standard of care." Thirty control patients underwent a second examination with no gel, and 40 other patients had the second examination with gel. All patients rated the discomfort of each Papanicolaou smear on a numerical pain scale. Main outcome measures were cytologic discrepancies on standard glass slide samples and comfort differences regarding the use of gel lubrication. Fisher's exact test was used to interpret the effect of gel on cytology results. Student's t test was performed to compare the discomfort ratings for the second Papanicolaou smear in the GEL vs. the NO GEL groups.Results: There was no statistically significant difference between the number of inadequate Papanicolaou smears (P ‫؍‬ .50) nor in the discomfort level ratings in the GEL vs. the NO GEL groups (P ‫؍‬ .69). Conclusion: Speculum gel lubrication does not affect cervical cytology during the traditional Papanicolaou smear, nor does it provide significant alteration of patient discomfort. (J Am Board Fam Med 2006;19:340 -4.)The Papanicolaou smear is an effective and wellaccepted screening examination for the early detection of cervical cellular abnormalities. It has significantly decreased the morbidity and mortality from cervical cancer and is now a standard part of preventive health care for women of reproductive age.1,2 It is therefore important to get the most accurate and reliable cell specimens by using proper techniques.Despite its clinical importance, the Papanicolaou smear examination can be an awkward and unpleasant experience for many women. Physicians should thus be sensitive to this issue and take measures to make the smear as comfortable as possible for the patient.In medical training, students/residents are taught never to use water-soluble gel to lubricate the speculum in the collection process. 4,5 The presumable theory behind this teaching is that the gel may obscure the cellular preparation via gel overlay or altered uptake of dye in staining. However, a lack of literature exists to support this dogma, and recent literature refutes it. 6,7 Discussion with colleagues shows that many feel the use of gel lubricant allows for easier entry of the speculum into the vagina and that it is more comfortable for the patient.The goals of the current study were to formally investigate whether gel obscures cerv...

Background Management of patients with interstitial lung disease (ILD) requires subspecialized, comprehensive, multidisciplinary care. The Pulmonary Fibrosis Foundation established the Care Center Network (CCN) in 2013 with identified criteria to become a designated CCN site. Despite these criteria, the essential components of an ILD clinic remain unknown. Research Questions How are ILD clinics within the CCN structured? What are the essential components of an ILD clinic according to ILD physician experts, patients, and caregivers? Study Design and Methods This study had 3 components. First, all 68 CCN sites were surveyed to determine the characteristics of their current ILD clinics. Second, an online, three-round modified Delphi survey was conducted between October and December 2019 with 48 ILD experts participating in total. Items for round one were generated using expert interviews. During rounds 1 and 2, experts rated the importance of each item on a 5-point Likert scale. The a priori threshold for consensus was greater than 75% of experts rating an item as important or very important. In round 3, experts graded items that met consensus and ranked items deemed essential for an ILD clinic. Third, ILD patient and caregiver focus groups were conducted and analyzed for content to determine their perspectives of an ideal ILD clinic. Results Forty items across four categories (members, infrastructure, resources and multidisciplinary conference) achieved consensus as essential to an ILD clinic. Patient and caregiver focus groups identified three major themes: comprehensive, patient-centered medical care; expanded access to care; and comprehensive support for living and coping with ILD. Interpretation The essential components of an ILD clinic are well-aligned between physician experts and patients. Future research can use these findings to evaluate the impact of these components on patient outcomes and inform best-practices for ILD clinics throughout the world.
