Serotonin discontinuation syndrome following utero exposure to antidepressant medication : prospective controlled study

Objectives: The aim of the present study was to examine neonatal symptoms previously reported to be associated with exposure to antidepressant medication in late pregnancy in a group of infants exposed to antidepressants, using a prospective and controlled design.

Method: A prospective case-control study recruited 27 pregnant women taking antidepressant medication and 27 matched controls who were not taking antidepressant medication in pregnancy. Of the 27 women taking medication, 25 remained on medication in the third trimester and, of these, 23 women had complete data available. In pregnancy and after delivery women were assessed with the Beck Depression Inventory-II and a purpose-designed questionnaire. After delivery mothers were asked a set of nine questions pertaining to symptoms of discontinuation in their newborn and questions about pregnancy and delivery complications.

Results: There was an increased risk of discontinuation symptoms in neonates exposed to antidepressant medication in late pregnancy and an association with higher dose medication. The study group were found to be significantly more likely to display behaviour such as crying, jitteriness, tremor, feeding, reflux and sneezing and sleep for <3 h after a feed. They also had significantly higher rates of jaundice and admissions to the special care nursery.

Conclusions: Exposure to antidepressants in late pregnancy is associated with a range of symptoms in the neonate that are consistent with the effects of exposure to antidepressants in late pregnancy. The clusters of symptoms most highly correlated are the gastrointestinal and central nervous system symptoms. These finding helps to identify the common symptoms associated with a neonatal serotonin discontinuation syndrome.

Effect of deer velvet on sexual function in men and their partners: a double-blind, placebo-controlled study

The use of alternative medicines and herbal remedies is an increasing trend in Western societies. For years, people have taken products made of deer velvet for their alleged beneficial effects on sexual function. There has been no scientific investigation of the effects of deer velvet powder on the sexual functioning of human males. This study investigated sexual function in men during a 12-week double-blind, placebo-controlled trial of deer velvet. Thirty-two volunteer male participants, aged 45–65 years, and their partners, were randomly assigned to either the deer velvet or placebo study group. The males took capsules containing ground deer velvet or placebo everyday for 12 weeks. Two sexual function questionnaires (the International Index of Erectile Function and the Brief Index of Sexual Function for Women) used at pre- and posttreatment assessed changes in sexual functioning in males and their partners. Blood tests at baseline, and end of study, determined levels of sex-related hormones in male participants. There were no significant differences in the sexual behavior of the men taking deer velvet compared with the men taking placebo capsules. There were no significant hormone changes from baseline to the end of the study in either group of men. We conclude that in normal males there was no advantage in taking deer velvet to enhance sexual function. All alternative health products or nutritional supplements should be subjected to randomized placebo-controlled trials to determine efficacy.

A pilot randomized, double-blind, placebo-controlled study of granisetron in the treatment of sexual dysfunction in women associated with antidepressant use

A pilot study was conducted to evaluate the usefulness of granisetron for the treatment of antidepressant induced sexual dysfunction in women. Twelve women with antidepressant induced sexual dysfunction (AISD) were assigned granisetron (n=5) or placebo (n=7) in a 14-day randomized, double-blind, placebo-controlled study. One participant in the granisetron group did not complete the study. Participants were assessed at baseline, day 7 and day 14 using the Feiger Sexual Function and Satisfaction Questionnaire and the Arizona Sexual Experience Scale. No statistical differences were measured at baseline or at endpoint between the granisetron or placebo group. This study did not produce evidence supporting the usefulness of granisetron in AISD.

Severe obesity and diabetes self-care attitudes, behaviours and burden: implications for weight management from a matched case-controlled study.

Aims
To investigate whether diabetes self-care attitudes, behaviours and perceived burden, particularly related to weight management, diet and physical activity, differ between adults with Type 2 diabetes who are severely obese and matched non-severely obese control subjects.

Methods
The 1795 respondents to the Diabetes MILES—Australia national survey had Type 2 diabetes and reported height and weight data, enabling BMI calculation: 530 (30%) were severely obese (BMI ≥ 35 kg/m2; median BMI = 41.6 kg/m2) and these were matched with 530 control subjects (BMI < 35 kg/m2; median BMI = 28.2 kg/m2). Diabetes self-care behaviours, attitudes and burden were measured with the Diabetes Self-Care Inventory—Revised. Within-group and between-group trends were examined.

Results
The group with BMI ≥ 35 kg/m2 was less likely to achieve healthy diet and exercise targets, placed less importance on diet and exercise recommendations, and found the burden of diet and exercise recommendations to be greater than the group with BMI < 35 kg/m2. The group with BMI ≥ 35 kg/m2 was more likely to be actively trying to lose weight, but found weight control a greater burden. These issues accentuated with increasing obesity and were greatest in those with BMI > 45 kg/m2. There were no between-group differences in other aspects of diabetes self-care: self-monitoring of blood glucose, use of medications and smoking. Moderate-to-severe symptoms of depression were independently associated with reduced likelihood of healthy diet and physical activity, and with greater burden associated with diet, physical activity and weight management.

Conclusions
Severely obese people with diabetes demonstrated self-care attitudes, behaviours and burdens that infer barriers to weight loss. However, other important diabetes self-care behaviours are supported equally by severely obese and non-severely obese individuals.

Efficacy of mirtazapine add on therapy to haloperidol in the treatment of the negative symptoms of schizophrenia: a double-blind randomized placebo-controlled study.

The negative symptoms of schizophrenia remain a major clinical challenge. Mirtazapine is an antidepressant with antagonist properties at 5-HT2A, 5-HT3 and alpha 2 receptors as well as indirect 5-HT1a agonist effects. Many of these pharmacological actions have clinical or preclinical evidence of efficacy in schizophrenia. This study was a 6-week randomized placebo-controlled trial of mirtzepine or placebo add on to haloperidol 5 mg in the treatment of 30 patients with DSM-IV schizophrenia. The primary finding of the trial was a 42% reduction in Positive and Negative Syndrome Scale (PANSS) negative symptom scores in the mirtazapine group compared to placebo at the end of 6 weeks (mirtazapine 13.9, SD 1.56; placebo 23.9, SD 1.56; P = 0.000, F = 20.31, d.f. = 1). The PANNS total scores, Clinical Global Impression severity and improvement scales in addition showed superiority of mirtazapine over placebo. There was no difference between the groups on the Hamilton depression scale at endpoint, suggesting that the improvement in negative symptoms was not an artifact of mood improvement. These results suggest a potential role for mirtazapine in the negative symptoms of schizophrenia.

Reboxetine add on therapy to haloperidol in the treatment of schizophrenia: a preliminary double-blind randomized placebo-controlled study.

The negative symptoms of schizophrenia remain a major clinical challenge. Reboxetine is an antidepressant whose major mechanism of action is as a noradrenergic reuptake inhibitor. This study was a 6-week randomized placebo-controlled trial of reboxetine or placebo add on to haloperidol 5 mg in the treatment of 30 patients with DSM-IV schizophrenia. The trial failed to demonstrate any significant difference between the placebo and reboxetine groups on any of the outcome measures. This trial does not suggest that increased noradreneregic drive mediated by reuptake inhibition in patients taking dopamine antagonists is of therapeutic value in schizophrenia.
