The study was conducted to investigate the platelet increasing property of Carica papaya leaves juice (CPLJ) in patients with dengue fever (DF). An open labeled randomized controlled trial was carried out on 228 patients with DF and dengue haemorrhagic fever (DHF). Approximately half the patients received the juice, for 3 consecutive days while the others remained as controls and received the standard management. Their full blood count was monitored 8 hours for 48 hours. Gene expression studies were conducted on the ALOX 12 and PTAFR genes. The mean increase in platelet counts were compared in both groups using repeated measure ANCOVA. There was a significant increase in mean platelet count observed in the intervention group (P < 0.001) but not in the control group 40 hours since the first dose of CPLJ. Comparison of mean platelet count between intervention and control group showed that mean platelet count in intervention group was significantly higher than control group after 40 and 48 hours of admission (P < 0.01). The ALOX 12 (FC = 15.00) and PTAFR (FC = 13.42) genes were highly expressed among those on the juice. It was concluded that CPLJ does significantly increase the platelet count in patients with DF and DHF.
Background: Diabetes mellitus is a lifelong chronic condition that requires self-management. Lifestyle modification and adherence to antidiabetes medications are the major determinants of therapeutic success in the management of diabetes.
Purpose: To assess the effects of a pharmaceutical care (PC) model on medication adherence and glycemic levels of people with type 2 diabetes mellitus.
Patients and methods: A total of 241 people with type 2 diabetes were recruited from a major teaching hospital in Malaysia and allocated at random to the control (n=121) or intervention (n=120) groups. Participants in the intervention group received PC from an experienced pharmacist, whereas those in the control group were provided the standard pharmacy service. Medication adherence was assessed using the Malaysian Medication Adherence Scale, and glycemic levels (glycated hemoglobin values and fasting blood glucose [FBG]) of participants were obtained at baseline and after 4, 8, and 12 months.
Results: At baseline, there were no significant differences in demographic data, medication adherence, and glycemic levels between participants in the control and intervention groups. However, statistically significant differences in FBG and glycated hemoglobin values were observed between the control and intervention groups at months 4, 8, and 12 after the provision of PC (median FBG, 9.0 versus 7.2 mmol/L [P<0.001]; median glycated hemoglobin level, 9.1% versus 8.0% [P0.001] at 12 months). Medication adherence was also significantly associated with the provision of PC, with a higher proportion in the intervention group than in the control group achieving it (75.0% versus 58.7%; P=0.007).
Conclusion: The provision of PC has positive effects on medication adherence as well as the glycemic control of people with type 2 diabetes. Therefore, the PC model used in this study should be duplicated in other health care settings for the benefit of more patients with type 2 diabetes.

BACKGROUD: Previous studies have shown that the blood pressure elevating effect of acute caffeine consumption was variable because of the heterogeneity of study participants, dosage of caffeine and study designs.
OBJECTIVE: This research aimed to examine the effect of a single cup of coffee on the blood pressure of young adults.
METHODS: Normotensive adults were randomised to receive either a cup of caffeinated drink (intervention group) or a cup of decaffeinated drink (control group). The main outcome measure was mean change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) between intervention and control groups.
RESULTS: Enrolled participants (n = 104) were randomly assigned to the intervention group (n = 53) or the control group (n = 51). The mean differences in SBP and DBP of the two groups were +2.77 mmHg (P = 0.05) and +2.11 mmHg (P = 0.64), respectively. Therefore, the rise in both SBP and DBP after caffeine consumption was not statistically significant.
DISCUSSION: Our study confirmed that drinking a single cup of coffee (containing 80 mg of caffeine) does not have a significant impact on the blood pressure of healthy normotensive young adults one hour after the drink.
INTRODUCTION: Migraine is a common disabling condition that results in considerable socioeconomic loss. The role of non-steroidal anti-inflammatory drugs (NSAIDs) in acute migraine has been well-established. We compared the efficacy of the cyclooxygenase-2 inhibitor celecoxib with the NSAID, naproxen sodium, in the treatment of acute migraine.
METHODS: This was a randomised, open label, controlled trial. We selected patients with a diagnosis of migraine, based on the International Headache Society revised criteria. 60 patients were randomised to either celecoxib 400 mg (30 patients) or naproxen sodium 550 mg (30 patients). Patients took the study medicine for the first acute migraine episode that occurred during the study period and reported the headache reduction based on a visual analogue score (VAS). Patients were reviewed after a month to check on VAS at one and two hours, compared to the baseline. Any side effects of the medication were also recorded.
RESULTS: Of the 52 patients who completed the study, eight did not experience any headaches. The mean VAS in the celecoxib group improved significantly from baseline (6.48 +/- 1.53) to one hour (4.28 +/- 2.11) and two hours (2.24 +/- 2.57) (p-value is less than 0.0005). The mean VAS in the naproxen sodium group also improved significantly from baseline (7.30 +/- 1.66) to one hour (4.81 +/- 2.50) and two hours (2.63 +/- 2.65) (p-value is less than 0.0005). However, there was no significant difference between the magnitudes of improvement between the treatment groups. The incidence of gastric pain was significantly higher in the naproxen sodium group (p-value is equal to 0.029).
CONCLUSION: In comparison with naproxen sodium, celecoxib was equally effective in relieving pain in acute migraine and caused significantly less gastric pain.

Smoking deception is often ignored, but is important in health care. In this trial it was assessed at both study entry and outcome. At study entry, 1,044 males at a primary care clinic were asked smoking status and tested for breath carbon monoxide (CO). Of self-reported non-smokers, 57/402 (14%) were actually smokers, as were 59/251 (24%) of self-reported ex-smokers. The self-reported smokers (n=387) entered a randomized, controlled trial where the intervention comprised four questions on knowledge and beliefs about smoking, standardized verbal advice against smoking, and a leaflet. At follow-up, subjects were also questioned about beliefs. Follow-up was difficult, but 191/387 (49%) attended at three or six months. Of 27 who claimed to have quit, 6 (22%) were deceivers and 21 were confirmed quitters. Cessation did not differ between intervention and control groups. Overall confirmed cessation at six months was 16/387 (4.1 %). Confirmed quitters were significantly lighter smokers than deceivers and still smokers. There were non-significant trends between the outcome groups whereby deceivers had least knowledge and most lay beliefs, and quitters had most knowledge and fewest lay beliefs. The lay beliefs may prevent some smokers from quitting.
