Pulmonary pulse wave transit time (pPTT), defined as the time for the systolic pressure pulse wave to travel from the pulmonary valve to the pulmonary veins, has been reported to be reduced in pulmonary arterial hypertension (PAH); however, the underlying mechanism of reduced pPTT is unknown. Here, we investigate the hypothesis that abbreviated pPTT in PAH results from impaired right ventricular-pulmonary artery (RV-PA) coupling. We quantified pPTT using pulsed-wave Doppler ultrasound from 10 healthy age- and sex-matched controls and 36 patients with PAH...

BACKGROUND: Hospitalization of patients with chronic obstructive pulmonary disease (COPD) places a huge healthcare burden. Positive airway pressure (PAP) therapy is sometimes used in COPD patients, but the possible impact on hospitalization risk remains controversial. We studied the hospitalization risk of COPD patients before and after initiation of various PAP therapies in a "real-world" bioinformatics study. METHODS: We performed a retrospective analysis of administrative claims data of hospitalizations in patients with COPD who received or did not receive PAP therapy - continuous PAP, bilevel PAP, and non-invasive positive pressure ventilation using a home ventilator (NIPPV)...

Biliary tumors showing intraductal papillary growth (Pap-BT) include intraductal papillary neoplasm of the bile duct (IPNB) and papillary cholangiocarcinoma (CC). A differential diagnosis between IPNB and papillary CC currently remains challenging. The aim of the present study is to identify histological features and immunohistochemical markers of malignant potential such as tumor invasion in Pap-BT. Subjects comprised 37 patients with Pap-BT (intrahepatic and perihilar (proximal), 27; 17 non-invasive and 10 invasive); distal 10, all invasive)...

Pulmonary alveolar proteinosis (PAP) is a rare diffuse lung disease in the pediatric population. There are currently few cases documenting hemophagocytic lymphohistiocytosis as a cause for secondary PAP. We describe an ex-preterm child with secondary hemophagocytic lymphohistiocytosis, complicated by PAP and hypoxemic respiratory failure.

BACKGROUND: Underserved ethnic minority women experience significant disparities in cervical cancer incidence and mortality, mainly due to lack of cervical cancer screening. Barriers to Pap smear screening include lack of knowledge, lack of health insurance and access, and cultural beliefs regarding disease prevention. In our previous SUCCESS trial, we demonstrated that HPV self-sampling delivered by a community health worker (CHW) is efficacious in circumventing these barriers. This approach increased screening uptake relative to navigation to Pap smear screening...

BACKGROUND: In moderately to severely obese patients with obstructive sleep apnea (OSA), the effects of long-term positive airway pressure (PAP) treatment on cardiovascular risk are poorly defined. PURPOSE: To assess the effect of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) on the occurrence of cardiovascular events in obese OSA patients. METHODS: We performed a noninterventional observational study in obese OSA patients recruited between 2007 and 2010 at the Sleep Center, University of Grenoble, treated with CPAP or NIV, and followed for 5...

INTRODUCTION: During Robotic-Assisted Radical Prostatectomy (RARP), the prostate may be approached extraperiteoneally (eRARP) or transperitoneally (tRARP). The former avoids the abdominal cavity which might be of benefit in patients who have had prior abdominal or pelvic surgery (PAPS). Our objective was to compare the outcomes of patients with PAPS undergoing either technique. METHODS: A retrospective review of patients treated with RARP from July 1, 2003-Dec. 31, 2014 with a minimum follow-up of 3 months was undertaken...

In 2014 many uninsured, low-income nonelderly adults gained access to health insurance in states that expanded Medicaid eligibility under the Affordable Care Act. Federally funded community health centers were likely to be particularly affected by this expansion because many of their patients were uninsured and low income. We used a difference-in-differences approach to compare changes among 1,057 such centers in expansion versus nonexpansion states from 2011 to 2014, in terms of their patients' insurance coverage, the number of patients they served, and the quality of care they provided...

Nutrient sulfate is essential for numerous physiological functions in mammalian growth and development. Accordingly, disruptions to any of the molecular processes that maintain the required biological ratio of sulfonated and unconjugated substrates are likely to have detrimental consequences for mammalian physiology. Molecular processes of sulfate biology can be broadly grouped into four categories: firstly, intracellular sulfate levels are maintained by intermediary metabolism and sulfate transporters that mediate the transfer of sulfate across the plasma membrane; secondly, sulfate is converted to 3'-phosphoadenosine 5'-phosphosulfate (PAPS), which is the universal sulfonate donor for all sulfonation reactions; thirdly, sulfotransferases mediate the intracellular sulfonation of endogenous and exogenous substrates; fourthly, sulfate is removed from substrates via sulfatases...

BACKGROUND: Transthoracic echocardiography (TTE) and computerized axial tomography (CT) are complementary imaging techniques. It is possible that a combination of the two may offer a better way of identifying pulmonary hypertension (PH) than either one alone. OBJECTIVES: To determine the diagnostic accuracy of TTE combined with chest CT in pulmonary hypertension. METHODS: We performed a retrospective review of consecutive patients who had undergone TTE, CT and right heart catheterization (RHC) between 7/1/2008 and 6/30/2012...

BACKGROUND: Prostate cancer (CP) cells differ from their normal counterpart in gene expression. Genes encoding secreted or extracellular proteins with increased expression in CP may serve as potential biomarkers. For their detection and quantification, assays based on monoclonal antibodies are best suited for development in the clinical setting. One approach to obtain antibodies is to use recombinant proteins as immunogen. However, the synthesis of recombinant protein for each identified candidate is time-consuming and expensive...
