BACKGROUND: The pathogenesis of normal pressure hydrocephalus (NPH) remains unclear which limits both early diagnosis and prognostication. The responsiveness to intervention of differing, complex and concurrent injury patterns on imaging have not been well-characterized. We used diffusion tensor imaging (DTI) to explore the topography and reversibility of white matter injury in NPH pre- and early after shunting. METHODS: Twenty-five participants (sixteen NPH patients and nine healthy controls) underwent DTI, pre-operatively and at two weeks post-intervention in patients...

INTRODUCTION: Type 2 diabetes mellitus (T2DM) has attained epidemic proportions and continues to increase despite the availability of a number of oral antidiabetic medications and major advances made in insulin delivery since its discovery nearly a hundred years ago. One, amongst many other reasons responsible for the inability to achieve adequate glycaemic control in a substantial proportion of T2DM patients is the delayed initiation and inappropriate intensification of insulin treatment...

The synthesis of bis(N1-phenyl-5-hydroxypyrazol-3-yl)pyridines ("L") is described, and these are silylated to achieve analogues ("Si2L") without the variable of the hydroxyl proton mobility. One hydroxyl example is characterized in its bis-pincer iron(II) complex, which shows every OH proton involved in hydrogen bonding. The steric bulk of the silylated N-phenyl-substituted ligands allows the synthesis and characterization of paramagnetic (Si2L)FeCl2 complexes, and one of these is reduced, under CO, to give the diamagnetic (Si2L)Fe(CO)2 species...

Reasonable glycemic control is difficult to achieve in patients with diabetes mellitus (DM) receiving continuous enteral nutrition therapy (CENT). There are no solid evidence-based medicine guidelines regarding this issue in these patients. The purpose of this study was to determine if the use of a basal-bolus insulin regimen is more effective than neutral protamine Hagedorn (NPH) insulin alone in controlling blood glucose in non-critically ill patients with DM receiving CENT. We performed a retrospective, records-based review comparing basal-bolus with NPH insulin regimen in these patients, hospitalized in the internal medicine wards in our hospital...

Subacute ruminal acidosis (SARA) is usually characterized by abnormal and intermittent drops in rumen pH. Nevertheless, high individual animal variability in rumen pH and the difference in measurement methods for pH data acquisition decrease the sensitivity and accuracy of pH indicators for detecting SARA in ruminants. The aim of this study was to refine rumen pH indicators in long-term SARA based on individual dairy cow reticulo-rumen pH kinetics. Animal performances and rumen parameters were studied weekly in order to validate SARA syndrome and rumen pH was continuously measured using reticulo-rumen sensors...

CLINICAL CASE: The case is presented of a 73-year-old male patient who referred to having black and white vision. Computed tomography showed normal pressure hydrocephalus (NPH). Magnetic resonance imaging was not performed because the patient refused to undergo further examinations. DISCUSSION: Achromatopsia may be the first or only NPH symptom. It may be prudent to ask patients with NPH regarding colour vision.

BACKGROUND: To maintain fasting blood glucose levels within near to the normal range in type 1 diabetes mellitus (DM), frequent insulin dose adjustments may be required with short-, intermediate- and long-acting insulin formulations. Patients on human insulin generally experience weight gain over time, regardless of the level of glycaemic control achieved. OBJECTIVES: To determine the effects of human insulin, adjusted quarterly to achieve glycaemic control, on body mass index (BMI), and establish dose regimens that achieve optimal glycaemic control without increasing BMI in patients with type 1 DM at the Kalafong Diabetes Clinic in Pretoria, South Africa...

AIMS: This study measured the insulin concentration (Ins[C]) of NPH insulin in vials and cartridges from different companies after either resuspension (R+) or not (R-; in the clear/cloudy phases of unsuspended NPH). METHODS: Measurements included Ins[C] in NPH(R+) and in the clear/cloudy phases of NPH(R-), and the time needed to resuspend NPH and time for NPH(R+) to separate again into clear/cloudy parts. RESULTS: In vials of NPH(R+) (assumed to be 100%), Ins[C] in the clear phase of NPH(R-) was<1%, but 230±41% and 234±54% in the cloudy phases of Novo Nordisk and Eli Lilly NPH, respectively...

Critical closing pressure (CrCP) is the arterial blood pressure (ABP) threshold, below which small arterial vessels collapse and cerebral blood flow ceases. Here we aim to compare three methods for CrCPestimation in scenario of a controlled increase in intracranial pressure (ICP), induced by infusion tests performed in patients with suspected normal pressure hydrocephalus (NPH). METHODS: Computer recordings of directly-measured ICP, ABP and transcranial Doppler cerebral blood flow velocity (CBFV), from 37 NPH patients undergoing infusion tests, were retrospectively analyzed...

This article reviews pharmacokinetic (PK) and pharmacodynamic (PD) concepts relating to the pharmacology of basal insulin analogs. Understanding the pharmacology of currently available long-acting basal insulins and the techniques used to assess PK and PD parameters (e.g. the euglycemic clamp method) is important when considering the efficacy and safety of these agents, and can help in understanding the rationale for specific dosing strategies when tailoring therapy for a specific patient. Basal insulins such as insulin glargine 100 units (U)/mL and insulin detemir show improved PK/PD characteristics compared with the intermediate-acting NPH insulin, with a longer duration of action, a more consistent glucose-lowering effect and less prominent concentration peaks...
