Randomized controlled trials have been unable to detect a cardiovascular benefit of continuous positive airway pressure (CPAP) in unselected patients with obstructive sleep apnea (OSA). We hypothesize that deleterious cardiovascular outcomes are concentrated in a subgroup of patients with heightened apnea/hypopnea-related pulse rate response.
We measured the pulse rate response to apneas/hypopneas (∆HR) in the Multi-Ethnic Study of Atherosclerosis (MESA, N=1395) and the Sleep Heart Health Study (SHHS, N=4575). MESA data were used to determine the functional form of association between ∆HR and subclinical cardiovascular biomarkers, while primary analyses tested the association of ∆HR with non-fatal/fatal CVD and all-cause mortality in longitudinal data from the SHHS.
In MESA, U-shaped relationships were observed between subclinical CVD biomarkers (coronary artery calcium; NT-proBNP; Framingham risk score) and ∆HR; notably, high ∆HR (upper quartile) was associated with elevated biomarker scores compared tselection for future clinical trials.
The physiological basis of lung protection and the impact of PEEP during pronation in ARDS are not fully elucidated.
To compare pleural pressure (Ppl) gradient, ventilation distribution and regional compliance between dependent and non-dependent lung, and investigate the effect of PEEP during supination and pronation.
We used a 2-hit model of lung injury (saline lavage and high-volume ventilation) in 14 mechanically ventilated pigs and studied supine and prone position. Global and regional lung mechanics including Ppl and distribution of ventilation (Electrical Impedance Tomography) were analyzed across PEEP steps from 20 to 3 cm H2O. Two pigs underwent CT scan tidal recruitment and hyperinflation were calculated. Distribution of ventilation was studied in human cadavers.
Pronation improved oxygenation, increased Ppl, thus decreasing transpulmonary pressure for any PEEP, and reduced the dorsal-ventral pleural pressure gradient at PEEP < 10cmH2O. Distribution of ventilation was homogenized between dependent and non-dependent while prone and was less dependent on the PEEP level than supine. The highest regional compliance was achieved at different PEEP levels in dependent and non-dependent regions in supine (15 and 8 cmH2O), but for similar values in prone (13 and 12 cmH2O). Tidal recruitment was more evenly distributed (dependent/non-dependent), hyperinflation lower and lungs cephalocaudally longer in the prone position. Regional homogenization was also observed in a human cadaver.
In this lung injury model, pronation reduces the vertical pleural pressure gradient and homogenizes regional ventilation and compliance between the dependent and non-dependent regions. Homogenization is much less dependent on PEEP level in prone than in supine.

Current diagnostic tests fail to identify individuals at higher risk of progression to tuberculosis disease, such as those with recent Mycobacterium tuberculosis infection, who should be prioritized for targeted preventive treatment.
To define a blood-based biomarker, measured with a simple flow cytometry assay, that can stratify different stages of tuberculosis infection to infer risk of disease.
South African adolescents were serially tested with QuantiFERON-TB Gold to define recent (QuantiFERON-TB conversion <6 months) and persistent (QuantiFERON-TB+ for >1 year) infection. We defined the ΔHLA-DR median fluorescence intensity biomarker as the difference in HLA-DR expression between IFN-γ+TNF+ Mycobacterium tuberculosis-specific and total CD3+ T cells. Biomarker performance was assessed by blinded prediction in untouched test cohorts with recent versus persistent infection or tuberculosis disease, and unblinded analysis of asymptomatic adolescents with tuberculosis infection who remained healthypulations at risk are warranted.
The ΔHLA-DR biomarker can identify individuals with recent QuantiFERON-TB conversion and those with disease progression, allowing targeted provision of preventive treatment to those at highest risk of tuberculosis. Further validation studies of this novel immune biomarker in various settings and populations at risk are warranted.A quantitative fit test is performed using a benchtop instrument (e.g., TSI PortaCount) to assess the fit factor provided by a respirator when assigned to a worker. There are no wearable instruments on the market to measure protection factors while the respirator is in use. The aim of this study is to evaluate two new, wearable, quantitative instruments-a dual-channel optical particle counter (DC OPC) and a dual-channel condensation particle counter (DC CPC)-that would enable in-situ, real-time measurement of respirator workplace protection factor. KRIBB11 Respirator laboratory protection factors measured by the new instruments were compared to those measured with the TSI PortaCount on one test subject for three test aerosols (sodium chloride, incense, ambient) at target laboratory protection factors of 100, 300, and 1,000 for sodium chloride and ambient, and 75 and 500 for incense. Three replicates were performed for each test condition. Data were analyzed with a two-sided paired t-test at a significance level of 0.05. Laboratory protection factors measured with the DC CPC agree with those measured with the PortaCount whereas those from the DC OPC generally do not. Mean laboratory protection factors derived from the DC CPC are only statistically significantly different for mean values of a laboratory protection factor at ambient conditions for a target laboratory protection factor of 300 (p = 0.02) and for incense at a target laboratory protection factor of 75 (p = 0.03). Although statistically significant, the difference in laboratory protection factors derived from the DC CPC are not substantial in practice and may be explained by systematic uncertainty. In contrast, the DC OPC reports substantially larger mean laboratory protection factors, differing by about half an order of magnitude in extreme cases, and statistically significantly different mean laboratory protection factors for the sodium chloride aerosol for target laboratory protection factors of 100 and 300 (p = 0.01 and p = 0.01).
