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.
BACKGROUND: High infection burden among the residential aged care facility (RACF) population has long been recognised; however, existing infection prevention effort is often limited to infection surveillance activity. There is a scarcity of evidence to guide antimicrobial stewardship in the Australian RACF setting.
OBJECTIVE: This review summarises the current trends in antibiotic use and multi-drug resistant (MDR) organisms, challenges related to antibiotic prescribing and areas of suboptimal antibiotic prescribing for further improvement, particularly in the Australian RACF setting.
DISCUSSION: There is widespread antibiotic prescribing in RACF, which may lead to the emergence of antibiotic resistance. Accordingly, there is an immediate need for judicious antibiotic use in this high-risk population to curb the rapid emergence of MDR organisms and other adverse consequences associated with inappropriate antibiotic use, as well as to reduce healthcare costs.
Over the past few years, the intrauterine contraceptive device (IUD) has overcome many of the problems that had initially made it unpopular. Today it is probably the most cost effective reversible form of contraception available.
Shirley is a 42 year old woman who has rung you 5 days after returning from a 3 week resort holiday in Malaysia and Thailand. You saw her before her trip and administered a hepatitis A vaccine and advised her that she did not require anti malarial drugs as she was only going to large cities and beach resorts. She says she has had a high fever, headache and body aches for several days and that she feels exhausted, but is well enough to come to the surgery. When you see her later that morning, she looks fairly well, although she is moving rather gingerly. She says she has been resting, is drinking lots of fluids, has some anorexia, but no other significant symptoms. Examination reveals a temperature of 38 degrees C and she has a fine morbilliform rash on her body, limbs and neck. There are no other abnormal findings.
In a survey of 5233 patients seen in the clinics of three general practitioners, 339 patients were found to be doctor hoppers (6.48 per cent). Respiratory symptoms and fever were the commonest presentation affecting mainly the paediatric age group. No improvement in the symptoms was quoted as the most common reason for switching to another doctor. Many factors contributed to doctor hopping and these were best considered in relation to the illness, the patient and the doctor: From the point of prevention, the doctor himself has a significant role to play, particularly in improving the doctor-patient relationship and patient compliance.

BACKGROUND: Overactive bladder syndrome (OAB) is a common medical condition that causes significant distress and impact on the quality of life in women. Muscarinic receptor antagonists remain the mainstay of therapy, but they are limited by their efficacy and adverse effects. The objective of the article was to compare the clinical efficacy and tolerability of medications used to treat OAB in women through network meta-analysis.
METHODS: Data from eligible studies of commonly prescribed pharmacological agents in the treatment of OAB in women were entered into Net-MetaXL after a literature search using two online databases (PubMed and Cochrane). Studies between 31 July 2000 and 31 July 2015 were included in this study.
RESULTS: Five quantitative studies were eligible for analysis. The most efficacious drug to treat OAB in women appears to be solifenacin 10 mg once daily (OD), followed by oxybutynin 3 mg three times a day. However, solifenacin 10 mg OD caused more adverse effects that the other treatments.
DISCUSSION: Our results are similar to those of another systematic review. When considering efficacy, tolerability and cost, solifenacin 5 mg once daily is the drug of choice as it is more efficacious, albeit with more adverse effects, than other treatments. If solifenacin is unsuitable, oxybutynin 3 mg TDS is recommended.
