Aim: To examine how quality standards of dental undergraduate education, postgraduate training and qualifications together with confidence and barriers could be utilised to predict intention to provide inhalation sedation.
Methods: All 202 dentists working within primary dental care in NHS Highland were invited to participate. The measures in the questionnaire survey included demographic information, undergraduate education and postgraduate qualifications, current provision and access to sedation service, attitudes towards confidence, barriers and intention to provide inhalation sedation.
Aim: To conduct an exploratory investigation of public dental service (PDS) practitioners' planned sedation modality using a structural equation modelling approach, in order to identify the explanatory value of using the Index of Sedation Need (IOSN), or its component parts, to predict sedation modality in patients referred with dental anxiety.
Methods: A convenience sample of patients referred to the PDS for dental anxiety management was invited to take part. The IOSN was completed for each patient (patient dental anxiety, medical and behavioural indicators and dental treatment complexity) as well as the American Society of Anesthesiologists Physical Status Classification System and the Case Mix Tool.
Aim: To examine the use of dental therapist/hygienists to provide primary dental treatment in remote-rural areas with regard to their effectiveness, efficiency, sustainability, acceptability and costs (affordability).
Method: The structured literature review of studies indexed in Medline, Embase and CinAHL was conducted using search terms relevant to 'dental therapists' and 'remote-rural'. Remote-rural was defined as 'those (individuals) with a greater than 30-minute drive time to the nearest settlement with a population of greater than 10,000'.
Objective: Intensification of insulin therapy in patients with type 2 diabetes, while improving glycemic control, often leads to an increase in body weight and other markers of cardiovascular risk. The effects of pramlintide as an adjunct to basal insulin titration (without mealtime insulin) on glycemia and cardiovascular risk markers were examined.
Research Design And Methods: This was a post hoc analysis of a 16-week, double-blind, placebo-controlled study in patients with type 2 diabetes (N = 211) using insulin glargine (without mealtime insulin) +/- oral agents.
Background: The production of oxidative stress as a result of postprandial hyperglycaemia is now recognized as an important contributing factor in the development of diabetes complications. The objective of this study was to examine the effects of pramlintide on plasma concentrations of glucose and several markers of oxidative stress in patients with type 2 diabetes following a standardized meal.
Methods: This was a randomized, single-blind, placebo-controlled, crossover study conducted at two clinical research centres in the United States.
Evidence from rodent studies indicates that the beta-cell-derived neurohormone amylin exerts multiple effects on eating behavior, including reductions in meal size, intake of highly palatable foods, and stress-induced sucrose consumption. To assess the effect of amylin agonism on human eating behavior we conducted a randomized, blinded, placebo-controlled, multicenter study investigating the effects of the amylin analog pramlintide on body weight, 24-h caloric intake, portion sizes, "fast food" intake, and perceived control of eating in 88 obese subjects. After a 2-day placebo lead-in, subjects self-administered pramlintide (180 microg) or placebo by subcutaneous injection 15 min before meals for 6 wk without concomitant lifestyle modifications.

Objective: To assess the potential of pramlintide as an antiobesity agent, we assessed the weight effect, safety, and tolerability of pramlintide in non-insulin-treated obese subjects with and without type 2 diabetes at doses greater than previously studied.
Design/setting: We performed a randomized, double-blind, placebo-controlled, multicenter study.
Objective: We previously reported that a single preprandial injection (120 microg) of pramlintide, an analog of the beta-cell hormone amylin, reduced ad libitum food intake in obese subjects. To further characterize the meal-related effects of amylin signaling in humans, we studied a lower pramlintide dose (30 microg) in normal-weight subjects.
Research Methods And Procedures: In a randomized, double-blind, placebo-controlled, cross-over study, 15 healthy men (age, 24 +/- 7 years; BMI, 22.

We report a patient who had a history of deep vein thrombosis in a previous pregnancy. She was treated with heparins without any reactions in the index pregnancy. Subsequently, when the patient became pregnant again, she developed an acute cutaneous reaction to the low molecular heparin enoxaparin 3 weeks after initiation of therapy.

While amylin reduces food intake in rodents, pramlintide's effect on satiety and food intake in humans has not yet been assessed.
Methods: In this randomised, double-blind, placebo-controlled crossover study, 11 insulin-treated men with type 2 diabetes (age 60+/-9 years, BMI 28.
Heme oxygenase (HO) modulates the accumulation of leukocytes within the liver during the early stages of a systemic inflammatory response syndrome (SIRS), but the anti-inflammatory mechanism(s) remain to be tested. The influence of HO on the adhesion molecule expression within the liver and on circulating leukocytes was assessed. In addition, the effect of HO and nitric oxide synthase (NOS) on the liver microcirculation was tested.

Furthermore, NO and O(2)(-) may interact to produce peroxynitrite. The major aim of the present study was to assess the relative roles of NO, O(2)(-), and ONOO- in the regulation of nuclear factor kappaB (NF-kappaB) activity and subsequent E-selectin expression during the early stages of sepsis.

In vitro, nitric oxide (NO) decreases leukocyte adhesion to endothelium by attenuating endothelial adhesion molecule expression. In vivo, lipopolysaccharide-induced leukocyte rolling and adhesion was greater in inducible NO synthase (iNOS)-/- mice than in wild-type mice. The objective of this study was to assess E- and P-selectin expression in the microvasculature of iNOS-/- and wild-type mice subjected to acute peritonitis by cecal ligation and perforation (CLP).

In sepsis, the arterioles are hyporesponsive to vasoconstrictors and vasodilators. Sepsis also reduces the number of perfused capillaries, thereby impacting on oxygen diffusion to mitochondria.

The objectives of this study were to determine 1) the changes in endothelial cell adhesion molecule expression that occur in a clinically relevant model of sepsis and 2) the dependence of these changes on endotoxin [lipopolysaccharide (LPS)]. The dual radiolabeled monoclonal antibody technique was used to quantify the expression of E- and P-selectin in LPS-sensitive (C3HeB/FeJ) and LPS-insensitive (C3H/HeJ) mice that were subjected to acute peritonitis by cecal ligation and perforation (CLP). At 6 h after CLP, the expression of both E- and P-selectin was increased in the gut (mesentery, pancreas, and small and large bowel) compared with the sham-operated and/or control animals, with a more marked response noted in LPS-insensitive mice.

Cytokine release from inflammatory (CD14(+)) cells is reduced after repeated stimulation with lipopolysaccharide (LPS; LPS tolerance). However, it is not known whether LPS tolerance can be induced in CD14(-) cells. The aim of the present study was to determine whether endothelial cells [human umbilical vein endothelial cells (HUVEC)] could be rendered tolerant to LPS with respect to LPS-induced polymorphonuclear neutrophil (PMN) adhesion.
View Article and Find Full Text PDFExposing human umbilical vein endothelial cells (HUVECs) to anoxia/reoxygenation (A/R) results in an increase in polymorphonuclear leukocyte (PMN) adhesion to HUVECs. This A/R-induced hyperadhesion is completely prevented by a previous (24 hours earlier) exposure of HUVECs to A/R. This phenomenon has been termed "A/R tolerance.

Twenty-two patients were diagnosed as having simultaneous or concurrent presentation of prostate and bladder carcinomas between January 1970 and July 1986. The overall five-year survival was 40 percent, with patients presenting with prostate cancer doing better (50%) than those with bladder cancer (32%).
