Background: Cobalamin deficiency and peripheral neuropathy (PN) are commonly seen in HIV-infected adults. The level of urine methylmalonic acid (UMMA), a reliable indicator of tissue cobalamin status, was determined in HIV infected subjects with and without PN to establish this association. Methods: One hundred and ninety-eight (198) consenting HIV infected subjects with and without PN were rec...

OBJECTIVE Protease-nexin 1 (PN-1) belongs to the serpin superfamily and behaves as a specific thrombin inhibitor in the pericellular environment. Little is known about PN-1 expression and its regulation in the vascular system. In this study, we examined the expression of functionally active PN-1 in vitro in rat aortic smooth muscle cells and in vivo in rat arterial media and its regulation in h...

BACKGROUND Chlamydia pneumoniae (C pn) infection causes an acute inflammation in the respiratory system that may become persistent, but little is known about the long-term respiratory effects of C pn infections. AIM To estimate the long term respiratory effects of C pn with change in forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) as a main outcome variable. ME...

Nutrient intakes in preterm infants are frequently inadequate and are associated with worse neurodevelopmental outcome. Preterm infants take time to establish enteral intakes, and parenteral nutrition (PN) is now an integral component of care. Despite this, the evidence base for PN intakes is extremely limited. There remains uncertainty over safe initial and maximum amounts of macronutrients, a...

Workload pressure on pharmacies through increased demands for parenteral nutrition (PN) is leading to a growing trend in the use of commercially manufactured PN (‘standard feeds’) and away from individually ‘tailored’ prescriptions. This is sometimes justified on grounds of safety, although many areas of risk remain inherent in the process of PN provision. In fact there is little to suggest tha...

Catheter type, access technique, and the catheter position should be selected considering to the anticipated duration of PN aiming at the lowest complication risks (infectious and non-infectious). Long-term (>7-10 days) parenteral nutrition (PN) requires central venous access whereas for PN <3 weeks percutaneously inserted catheters and for PN >3 weeks subcutaneous tunnelled catheters or port s...

OBJECTIVES Locally advanced thymoma can often involve the phrenic nerve (PN) due to its location on the mediastinal pleura. However, en bloc resection including the PN may cause severe postoperative complications, especially in myasthenia gravis patients. The aim of the study was to determine whether a PN involved could be spared during thymoma resection. METHODS A retrospective study was con...

BACKGROUND AND OBJECTIVES Certain patients who undergo proximal jejunum resection are unable to undergo primary anastomosis and require exteriorization of the proximal jejunum. These patients usually have major problems with short bowel due to the high output of the stoma. The output of a proximal jejunostomy contains abundant amounts of enzymes and electrolytes. Therefore, it is a feasible app...
