Final Sample

Abstract The objective of this study was to analyze the effect of supplementation with creatine and glutamine on physical fitness of military police officers. Therefore, an experimental double blind study was developed, with the final sample composed by 32 men randomly distributed into three groups: a group supplemented with creatine (n=10), glutamine (n=10) and a placebo group (n=12) and evaluated in three distinct moments, in an interval of three months (T1, T2 and T3). The physical training had a weekly frequency of 5 sessions x 90 min, including strength exercises, local muscular resistance, flexibility and both aerobic and anaerobic capacity. After analyzing the effect of time, group and interaction (group x time) for measures that indicated the physical capabilities of the subjects, a significant effect of time for the entire variable was identified (p<0,05). However, these differences were not observed when the univaried intragroups and intergroups analysis was performed (p>0,05). In face of the results it was concluded that supplementation with creatine and glutamine showed no ergogenic effect on physical performance in military police officers.

AbstractLittle is known about long-term effects of homeopathic treatment. Following a double-blind, placebo controlled trial of classical homeopathy in chronic headaches, we conducted a 1-year observational study of 18 patients following the double-blind phase, and a complete follow-up study of all trial participants. Eighteen patients received free treatment for daily diary data (frequency, intensity, duration of headaches) over the course of 1 y. All patients enrolled in the double-blind study were sent a 6-week headache diary, a follow-up questionnaire, a personality inventory and a complaint list. Eighty-seven, of the original 98 patients enrolled returned questionnaires, 81 returned diaries. There was no additional change from the end of the trial to the one-year follow-up. The improvement seen at the end of the 12-week trial was stable after 1 y. No differential effects according to treatment after the trial could be seen. Patients with no treatment following the trial had the most improvement after 1 y. Five of 18 patients can be counted responders according to ARIMA analysis of single-case time-series. Patients with double diagnoses and longer treatment duration tended to have clearer improvements than the rest of the patients. Approximately 30% of patients in homeopathic treatment will benefit after 1 y of treatment. There is no indication of a specific, or of a delayed effect of homeopathy.

Dose Levels

Promazine was administered to six hyperactive retarded boys in a long-term double-blind study. There were four dose levels —40, 60, 80, and 160 mg per day. The effect on activity level was measured with actometers. There was no effect on daytime activity when the placebo and drug levels were compared. There was a significant but clinically unimportant effect on night time activity.

The authors studied the acute effects of "Guaraná", when compared to caffeine and placebo, (double blind study) on cognition, anxiety and sleep in 30 normal volunteers. Although results were negative it cannot be concluded that "Guaraná" is harmless. Other studies shall be undertaken, administering "Guaraná" on a long term basis, as popularly proclaimed.

We evaluated the effect of glimepiride plus metformin and rosiglitazone plus metformin on glucose, and on cardiovascular risk parameters such as lipoprotein(a) (Lp[a]) and homocysteine (HCT) in patients with type 2 diabetes and metabolic syndrome. Ninety-nine patients in the multicentre, randomized, double-blind study took metformin (1500 mg/day) plus glimepiride (2 mg/day) or rosiglitazone (4 mg/day) for 12 months. Changes in body mass index, glycosylated haemoglobin (HbA1c), Lp(a) and HCT were primary efficacy variables. Fasting plasma glucose (FPG), post-prandial plasma glucose (PPG) and homeostasis model assessment index were also used to assess efficacy. On average, HbA1c decreased by 9.1% and 8.1%, FPG decreased by 7.3% and 10.9%, and PPG decreased by 7.6% and 10.5%, respectively, in the glimepiride and rosiglitazone groups after 12 months. Patients receiving rosiglitazone experienced more rapid improvement in glycaemic control than those on glimepiride, and showed a significant improvement in insulin resistance-related parameters. There was a statistically significant decrease in basal homocysteinaemia in glimepiride-treated patients (−27.3%), but not in rosiglitazone-treated patients. Rosiglitazone plus metformin significantly improved long-term control of insulin resistance-related parameters compared with glimepiride plus metformin, although glimepiride treatment was associated with a slight improvement in cholesterolaemia, not observed in the rosiglitazone-treated patients, and with significant improvements in non-traditional risk factors for cardiovascular disease, such as basal homocysteinaemia and plasma Lp(a) levels.
