A prospective study of the cognitive and psychiatric effects of pituitary tumours and their treatments.

Neurocognitive complaints are common in patients with pituitary tumours, particularly in memory and concentration. Past studies have shown impairments in executive function and memory, but it is not clear whether these result from direct effects of the tumour (pressure or hormonal secretion), incidental damage from radiotherapy or surgical treatments, and/or mediating psychiatric factors. This study assessed cognitive function and psychiatric state of 86 pituitary tumour patients and 18 healthy controls, pre and post-treatment, to examine the effects of tumour aetiology and treatment type.

Nutrient intake of women with and without gestational diabetes with a specific focus on fatty acids.

Objective: Diet therapy is the cornerstone for the management of gestational diabetes mellitus (GDM). Women with GDM are commonly given dietary advice that broadly focuses on a reduction of total energy and fat consumption. We compared nutrient intake and specifically fatty acids of women with GDM who had received individualized nutritional counseling with those of non-diabetic women who did not.

Unfavorable effect of type 1 and type 2 diabetes on maternal and fetal essential fatty acid status: a potential marker of fetal insulin resistance.

Background: Pregestational maternal diabetes increases obesity and diabetes risks in the offspring. Both conditions are characterized by insulin resistance, and diabetes is associated with low membrane arachidonic (AA) and docosahexaenoic (DHA) acids.

Objective: We investigated whether type 1 and type 2 diabetes in pregnancy compromise maternal and fetal membrane essential fatty acids (FAs).

Plasma fatty acids of neonates born to mothers with and without gestational diabetes.

Women with gestational diabetes mellitus (GDM) and their neonates have lower levels of arachidonic (AA) and docosahexaenoic (DHA) acids in red cell membranes. It is not clear if this abnormality is restricted to red cells or is a generalised problem. We have investigated plasma fatty acids of neonates (venous cord) of GDM (n=37), and non-diabetic (n=31) women.

Type 1 diabetes compromises plasma arachidonic and docosahexaenoic acids in newborn babies.

The activity of delta6- and delta5-desaturase, enzymes required for the synthesis of AA and DHA, are impaired in human and experimental diabetes. We have investigated whether neonates of type 1 diabetic women have compromised plasma AA and DHA at birth. Cord blood was obtained from healthy babies born to mothers with (n = 31) and without (n = 59) type 1 diabetes.
