PURPOSE: In the United States, an estimated 8500 HIV (human immunodeficiency virus) positive women gave birth in 2014. This rate appears to be increasing annually. Our objective is to examine obstetrical outcomes of pregnancy among HIV-positive women. METHODS: A population-based cohort study was conducted using the Nationwide Inpatient Sample database (2003-2011) from the United States. Pregnant HIV-positive women were identified and compared to pregnant women without HIV...

Pulmonary hypertension (PH) and right ventricular function are the focus of cardiovascular effects of bronchopulmonary dysplasia (BPD). We assessed cardiac indexes reflecting systemic afterload and pulmonary venous back pressure as pathophysiologic factors. Cardiac parameters were measured by conventional echocardiography in 20 preterm infants with severe BPD and compared with those of 10 preterm infants with no BPD and 20 healthy term infants. In infants with severe BPD, PH was noted in 5 (25%) by tricuspid regurgitation Doppler jet ≥2...

BACKGROUND: Venous sinus stenting is an emerging treatment for patients with idiopathic intracranial hypertension and evidence of venous stenosis. Stents placed across the transverse and sigmoid sinuses often cover the vein of Labbé (VOL), a major anastomotic vein draining the cerebral hemisphere. The patency of the VOL after stenting and its clinical implications are poorly understood. METHODS: A retrospective analysis was performed of a prospectively collected database of patients undergoing venous sinus stenting...

Stasis dermatitis commonly occurs in older age. It is caused by venous hypertension resulting from retrograde flow due to incompetent venous valves, valve destruction, or obstruction of the venous system. Further tissue changes arise from an inflammatory process mediated by metalloproteinases, which are up-regulated by ferric ion from extravasated red blood cells. Stasis dermatitis presents initially as poorly demarcated erythematous plaques of the lower legs bilaterally, classically involving the medial malleolus...

The utility of the ear crease sign, anterior tragal crease (ATC), as a marker of atherosclerosis is yet to be established. The intima-media thickness of the common carotid artery (IMT-CCA) has been used as a noninvasive surrogate marker for atherosclerosis. History of traditional risk factors for atherosclerosis was obtained from 147 volunteers; ear examination was also performed and venous blood was drawn for laboratory analysis. The volunteers then underwent an ultrasonography measurement of the IMT-CCA. In univariate analysis, presence of ATC, age, underlying hypertension, diabetes mellitus, ischemic heart disease, cerebrovascular disease, cigarette smoking, low-density lipoprotein, and high-sensitivity C-reactive protein were significantly associated with the IMT-CCA...

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a common and fatal complication of congenital heart disease (CHD). PAH-CHD increases the risk for postoperative complications. Recent evidence suggests that perioperative goal-directed hemodynamic optimization therapy (GDHOT) significantly improves outcomes in surgery patients. Standard GDHOT is based on major solution volume, vasodilators and inotropic therapy, while novel GDHOT is based on major vasopressor and inotropic therapy...

BACKGROUND: A meta-analysis was performed to explore predicted factors of venous thromboembolism (VTE) after surgery in the treatment for spine degeneration diseases. SUMMARY OF BACKGROUND DATA: Many scholars have focused on VTE after spine surgery, but as for the risk factors of VTE have not reached a consensus. METHODS: An extensive search of literature, "spine or spinal," "degeneration," "after surgery or postoperation," and "venous thromboembolism" as key words, was performed in PubMed/MEDLINE, Embase, the Cochrane library, CNKI, and WANFANG databases...

The implementation of patient-centered care requires an individualized approach to hemodialysis vascular access, on the basis of each patient's unique balance of risks and benefits. This systematic review aimed to summarize current literature on fistula risks, including rates of complications, to assist with patient-centered decision making. We searched Medline from 2000 to 2014 for English-language studies with prospectively captured data on ≥100 fistulas. We assessed study quality and extracted data on study design, patient characteristics, and outcomes...

AIM: To establish the impact of portal hypertension (PH) on wait-list/post-transplant outcomes in patients with polycystic liver disease (PCLD) listed for liver transplantation. METHODS: A retrospective single-centre case controlled study of consecutive patients listed for liver transplantation over 12 years was performed from our centre. PH in the PCLD cohort was defined by the one or more of following parameters: (1) presence of radiological or endoscopic documented varices from our own centre or the referral centre; (2) splenomegaly (> 11 cm) on radiology in absence of splenic cysts accounting for increased imaging size; (3) thrombocytopenia (platelets < 150 × 10(9)/L); or (4) ascites without radiological evidence of hepatic venous outflow obstruction from a single cyst...

BACKGROUND: Posterior reversible leukoencephalopathy syndrome (PRES) is linked to various etiologies, foremost systemic hypertension. Its association with intracranial hypotension (IH), a potential sequela of various neurosurgical procedures, is under-recognized. We report a case of lumbo-peritoneal shunt induced IH resulting in PRES with the goal to increase awareness, and elaborate on the potential biological mechanism, based on the Monro-Kellie hypothesis. CASE DESCRIPTION: A 26-year-old woman with acquired immunodeficiency syndrome and epilepsy was admitted for recurrent cryptococcal meningitis and breakthrough seizures...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is still a grey area in the knowledge of the aetiology, diagnosis and management of neurosurgical diseases. The definition of IIH has been reviewed over time and many hypotheses have been expressed as cause of the disease. The literature supplies very little evidence-based information to guide our decision-making process when it comes to treat the disease. In this review we sum up the latest information regarding the aetiology and therapy of IIH...

BACKGROUND: Pulmonary hypertension (PH) exists when mean pulmonary artery pressure (mPAP) is 25 mm Hg or greater. mPAP of 35 mm Hg or greater, with increased pulmonary vascular resistance from portopulmonary hypertension, has been associated with increased post-liver transplant (LT) mortality. However, mPAP of 35 mm Hg or greater can also occur in the setting of normal pulmonary vascular resistance from a high flow state and/or increased pulmonary venous volume. We describe the frequency of patients with mPAP of 35 mm Hg or greater at LT and correlate their clinical outcomes with hemodynamic characteristics...

OBJECTIVE Idiopathic intracranial hypertension (IIH) may cause blindness due to elevated intracranial pressure (ICP). Venous sinus stenosis has been identified in select patients, leading to stenting as a potential treatment, but its effects on global ICP have not been completely defined. The purpose of this pilot study was to assess the effects of venous sinus stenting on ICP in a small group of patients with IIH. METHODS Ten patients for whom medical therapy had failed were prospectively followed. Ophthalmological examinations were assessed, and patients with venous sinus stenosis on MR angiography proceeded to catheter angiography, venography with assessment of pressure gradient, and ICP monitoring...
