Daily vs every other day administration of G-CSF following autologous peripheral stem cell transplantation: a prospective randomized study.

The purpose of the study was to evaluate whether every other day administration of G-CSF was as safe and efficient as daily administration of G-CSF on neutrophil engraftment following autologous peripheral stem cell transplantation (APSCT). Duration of G-CSF administration, incidence of blood stream infections, duration of febrile neutropenia, duration of non-prophylactic antibiotic therapy, transfusion requirements, duration of hospitalization and G-CSF costs were also studied. Forty-seven patients with diagnosis of lymphoma and multiple myeloma undergoing APSCT were randomized to receive post-transplant daily or every other day G-CSF therapy both beginning on day +1. Both groups were comparable with regard to patient characteristics. There was no significant difference in time to neutrophil engraftment (p=0.31). The duration of G-CSF administration was significantly less in the every other day group (p<0.001). There were no detectable differences seen in the number of febrile days, duration of non-prophylactic antibiotics, the incidence of blood stream infections, transfusion requirements and the duration of hospitalization. There was a trend towards a faster platelet recovery in the every other day group, although the difference was not statistically significant (p=0.059). The number of doses of G-CSF used per transplant is significantly reduced, resulting in a significant reduction in drug costs.

Night eating syndrome among patients with depression.

OBJECTIVE: The purpose of this study was to identify the rate of night eating syndrome (NES) in a depressed population. METHOD: The study sample was composed of 162 depressed patients and 172 healthy control participants. RESULTS: The rates of night eating in our sample with depression (35.2%) was higher as compared with healthy control participants (19.2%) (p less than 0.05). In addition, in the depression group, the rate of NES-positive patients did not differ in accordance with body mass index (BMI) classification (p more than 0.05). However, in the control group, the rate of NES-positive patients was significantly different with regard to BMI classification, and NES diagnosis was highest in the obese members of the control group (p less than 0.05). Multiple logistic regression analysis was then used to evaluate the relationships of four variables: depression, gender, education status and BMI with the diagnosis of NES. Results showed that significant independent predictors of NES were depression, gender, and a BMI of 25 or greater. DISCUSSION: This is the first study to find that depressed patients are at a significantly greater risk for NES. Depression, male gender and BMI may account for the high rate of NES found in this population.

Maras powder usage among Turkish psychiatric outpatients.

A kind of smokeless tobacco known as Maras powder, which is used in the southeastern region of Turkey, causes nicotine dependence. The aim of this study was to determine the usage of Maras powder among psychiatric outpatients and nonpsychiatric controls. The study group consisted of 276 psychiatric patients and 283 nonpsychiatric patients from psychiatry and family medicine outpatient clinics. A socio-demographic form, the Fagerström Test for Nicotine Dependence, and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders?4th Edition were given to the participants. The rates of Maras powder usage in the patient group (10.1%) were significantly higher than those in the control group (5.6%). Men were found to use Maras powder at a higher rate in both groups. The rates of Maras powder usage according to the psychiatric diagnosis were evaluated. This is the first study estimating Maras powder usage rates among psychiatric patients in Turkey. The study's limitations are noted.

Synergistic effect of [1H-[1,2,4]Oxadiazole[4,3-a]quinoxalin-1-one] and antidepressant drugs in the mouse forced swimming test: possible involvement of serotonergic pathway.

To augment the effects of classical antidepressant drugs by combination therapies in drug-resistant patients has been an emerging treatment strategy. In the present study, the potential synergistic effect of [1H-[1,2,4]Oxadiazole[4,3-a]quinoxalin-1-one] (ODQ) and antidepressant drugs in the forced swimming test was evaluated. While 5mg/kg intraperitoneal administration of imipramine, fluoxetine or desipramine caused no effect in the duration of immobility in the forced swimming test (sub-effective doses), higher doses (20, 10 and 10mg/kg, respectively) reduced the immobility period (effective doses). When sub-effective doses of ODQ (15mg/kg) and imipramine (5mg/kg) were applied, there was a significant reduction in the immobility time compared with those of each drug alone. Similarly the reduction seen with the effective dose of imipramine (20mg/kg) was also augmented by the co-administration of ODQ (15mg/kg). By its sub-effective dose, ODQ exerted statistically significant augmentations in the responses to either sub-effective (5mg/kg) or effective dose (10mg/kg) of fluoxetine. By contrast, desipramine was not influenced by the co-administration of ODQ (15mg/kg). None of the drugs used in the present study had any effects on the locomotor activity test over the dose range applied. The results show that co-administration of imipramine/fluoxetine and ODQ exhibits a supra-additive effect and that serotonergic rather than noradrenergic pathway may be involved in the synergistic effect of ODQ.
