Improved pregnancy rates for obese, infertile women following a group treatment program. An open pilot study.

Thirty-seven women with a mean initial weight of 98.5 +/- 18.7 kg completed a group treatment program for obese, infertile women. The program lasted for 24 weeks and included regular exercise and group discussion of topics such as coping with the psychological impact of infertility, developing healthy eating patterns, and the effects of obesity on reproductive physiology. There was significant weight loss (mean weight loss 6.2 +/- 4.5 kg, p < 0.001) and improvement on measures of self-esteem, anxiety, depression, and general health. Twenty-nine women became pregnant during the follow-up period (21-36 months). Two women were avoiding pregnancy, so only six who had completed the group program and wished to become pregnant had not conceived by the end of the follow-up period. A further five women did not complete the program as they became pregnant while attending the group. Our results suggest that active measures to improve mood and self-esteem, along with better nutrition and weight reduction through diet and exercise, can produce considerable improvement in the outcome of treatment for infertility in obese women.

A group program for obese, infertile women: weight loss and improved psychological health.

We report on a group program for obese infertile women. Sixty-four women completed the 24-week program, which included exercise, information about healthy eating and group discussion sessions. Their mean initial weight was 101.9 +/- 18.14 kg. The mean weight loss on completion of the program was 5.2 +/- 5.11 kg (p < 0.0001). There was significant improvement on ratings of self-esteem and depression. Changes to life-style and health which are known to improve fertility may be a useful precursor to invasive, high technology infertility treatment procedures.

5-HT2 receptor subtypes: a family re-united?

The current classification for 5-HT2 receptors accommodates three subtypes. In addition to the originally defined 5-HT2 receptor, sanctuary is now provided for the structurally related 5-HT1c receptor (now 5-HT2c) and at least one atypical 5-HT receptor subtype. The strong functional union of this family is reflected in the paucity of ligands that will discriminate between its subtypes and prompts some re-evaluation of the activities of compounds which may now be regarded as nonselective for the receptor subtypes in this class. In this article, Gordon Baxter and colleagues examine the pharmacology of both officially recognized and atypical 5-HT2 receptor subtypes. A number of novel selective agents are highlighted, some of which may prove useful for 5-HT2 receptor classification and, ultimately, clarify the mechanistic basis for current and future therapeutic strategies which target this receptor family.

Weight loss results in significant improvement in pregnancy and ovulation rates in anovulatory obese women.

Obesity can affect ovulation and the chances of pregnancy. In this prospective study, a weight loss programme was assessed to determine whether it could help infertile overweight anovulatory women to establish ovulation and assist in achieving pregnancy, ideally without further medical intervention. The subjects acted as their own historical controls. They underwent a weekly programme of behavioural change in relation to exercise and diet over 6 months; those who did not complete the 6 months were treated as the comparison group. Women in the study group lost an average of 6.3 kg, with 12 of the 13 subjects resuming ovulation and 11 becoming pregnant, five of these spontaneously. Fitness, diet and psychometric measurements all improved. Fasting insulin and testosterone concentrations dropped significantly, while sex hormone binding globulin concentrations rose. None of these changes occurred in the comparison group. Thus, weight loss with a resultant improvement in ovulation, pregnancy outcome, self-esteem and endocrine parameters is the first therapeutic option for women who are infertile and overweight.

Molecular surface comparison: application to drug design.

An interactive system for the display and manipulation of molecular surface properties is presented. The property at the molecular surface is mapped onto the sphere by gnomonic projection. This representation allows direct comparison of the surface properties of pairs of molecules. The system allows the user to explore the similarities between a pair of molecules in an interactive manner, and provides extensive visual (color-coded field and field difference maps) and numerical (rms difference value) aids to complement the user's chemical intuition. Examples of the use of the system to study beta-lactam compounds and phosphodiesterase inhibitors are presented.
