Little is known about factors associated with emphysema progression in cigarette smokers. We evaluated factors associated with change in emphysema and FEV1 in subjects with and without chronic obstructive pulmonary disease (COPD).

This retrospective study included subjects participating in the COPDGene study and who completed the 5-year follow-up, including inspiratory and expiratory computed tomography (CT) and spirometry. All paired CT scans were analyzed using micro-mapping, which classifies individual voxels as emphysema or functional small airway disease (fSAD). Presence and progression of emphysema and FEV1 were determined based on comparison to nonsmoker values. Logistic regression analyses were used to identify clinical parameters associated with disease progression.

3088 subjects were included with a mean ± SD age of 60.7±8.9 years, including 72 nonsmokers. In all GOLD stages, the presence of emphysema at baseline was associated with emphysema progression (Odds ratio (OR) GOLD 0 4.32; PRISm; 5.73; GOLD 1 5.16; GOLD 2 5.69; GOLD 3/4 5.55; all p≤0.01). If there was no emphysema at baseline, the amount of fSAD at baseline was associated with emphysema progression (OR for 1% increase GOLD 0 1.06; PRISm 1.20; GOLD 1 1.7; GOLD 3/4 1.08 all p ≤ 0.03). In 1735 subjects without spirometric COPD, progression in emphysema occurred in 105 (6.1%) subjects and only 21 (1.2%) had progression in both emphysema and FEV1.

The presence of emphysema is an important predictor of emphysema progression. In patients without emphysema, fSAD is associated with the development of emphysema. In subjects without spirometric COPD, emphysema progression occurred independently of FEV1 decline.

Early diagnosis is key to altering the course of disease as well as of informing family members of potential risk. This randomized prospective observational study compares the different testing modalities for AATD testing of at risk patients initiated in the Pulmonary Function Testing (PFT) laboratory. Providing a recommendation with prescription for serologic testing, providing a finger-stick testing method (AlphaKit), and provided a buccal swab testing method (AlphaID) were compared to the community standard of referring the patient back to the PFT ordering provider only. Results show that testing directly in the PFT laboratory has an Odds Ratio (OR) for completing testing of 35.14 (5.33 - 999.99), p-value of less then 0.0001, for buccal swab testing and an OR of 17.09 (2.58 - 729.99), p-value of 0.0002, for finger-stick testing compared to community standard. Providing a prescription was no better than referral back to the PFT ordering provider with OR of 2.61(0.33 - 119.36), p-value of 0.6412. Resources needed to perform testing by Respiratory Therapy were minimal with average time of 1 to 5 minutes per patient tested. Causes of testing refusal were also identified. In conclusion, direct testing for AATD by respiratory therapists at the conclusion of PFT testing shows a significant improvement in rates of testing, especially with testing that utilizes buccal swab sample collection.Progressive neuromuscular disease leads to muscle weakness or failure that produces loss of pulmonary function and clinical respiratory morbidity. Tracking pulmonary function in a practical and effective way is very important because it can help identify a stage of disease when a morbidity, such as inadequate airway clearance or respiratory failure, may be present. There are four general categories of pulmonary function outcome measures such as volume, flow, pressure, and gas exchange. These outcome measures have variable precision and accuracy in predicting clinical change, and practicality in performing them relative to age and condition. It is widely recommended to follow multiple measurements longitudinally and create an accurate and timely clinical picture. This manuscript will review the most commonly used and most practical measures for use in clinical practice and how they can help to assess morbidity, disease state, and help optimize patient management.
Evidence-based patient care requires clinicians to make decisions based on the best available evidence and researchers to provide new scientific knowledge. Clinician-scientists (i.e., registered nurses [RNs] and physicians with a PhD) make important contributions to health care; yet, their roles are not fully understood, supported, or recognized by healthcare leaders. Only a few studies have addressed the factors that enable RNs and physicians to simultaneously pursue both clinical work and research after earning a PhD.

To explore what factors have a bearing on the ability of RNs and physicians to pursue research and clinical work simultaneously after earning a PhD.

The study used a qualitative design based on open-ended, in-depth interviews. find more Data were analyzed using conventional content analysis.

Analysis of the data yielded a broad range of factors that RNs and physicians perceived to either facilitate or hinder continued research while simultaneously undertaking clinical work. Most of the perceivedical work can facilitate evidence-based practice. This information can be used for interventions aimed at improving the conditions for clinician-scientists.A detailed protocol for preparation 3'-glycoconjugated oligonucleotides is described based on one-pot immobilization of 4,4'-dimethoxytrityl-protected carbohydrates to a solid support followed by on-support peracetylation and automated oligonucleotide assembly. Compared to an appropriate building block approach and post-synthetic manipulation of oligonucleotides, this protocol may simplify the synthesis scheme and increase overall yield of the conjugates. Furthermore, the immobilization to a solid support typically increases the stability of reactants, enabling prolonged storage, and makes subsequent processing convenient. Automated assembly on these carbohydrate-modified supports using conventional phosphoramidite chemistry produces 3'-glycoconjugated oligonucleotides in relatively high yield and purity. © 2020 Wiley Periodicals LLC.
