Abstract: Of 2029 screened records, we included seven studies in the review and six in the meta-analysis. Risk of bias varied: the randomisation and allocation process was often not clearly described, five of seven studies were double-blind and there was almost no missing data. The quality of the evidence for mortality was high. Risk ratios for overall mortality for adjunctive corticosteroids were 0.56 (95% confidence interval (CI) 0.32 to 0.98) at one month and 0.59 (95% CI 0.41 to 0.85) at three to four months of follow-up. In adults, to prevent one death, numbers needed to treat are nine patients in a setting without highly active antiretroviral therapy (HAART) available, and 23 patients with HAART available. The three largest trials provided moderate quality data on the need for mechanical ventilation, with a risk ratio of 0.38 (95% CI 0.20 to 0.73) in favour of adjunctive corticosteroids. One study was conducted in infants, suggesting a risk ratio for death in hospital of 0.81 (95% CI 0.51 to 1.29; moderate quality evidence). The number and size of trials investigating adjunctive corticosteroids for HIV-infected patients with PCP is small, but the evidence from this review suggests a beneficial effect for adult patients with substantial hypoxaemia. There is insufficient evidence on the effect of adjunctive corticosteroids on survival in infants.

Plain-language summary: The number and size of the trials investigating adjunctive corticosteroids for HIV-infected patients co-infected with PCP is small (the six trials included in the meta-analysis comprised 242 individuals in the intervention groups and 247 individuals in the control groups; the trial on infants comprised 47 individuals in the intervention group and 53 in the control group). Follow-up ranged from three to 14 months. The evidence from this review was of high quality for mortality and of moderate quality for need for mechanical ventilation and suggests a beneficial effect for adult patients with substantial hypoxaemia. For infants (18 months or younger) with HIV and suspected PCP there is insufficient evidence on whether the effect of adjunctive corticosteroids could improve survival (the confidence interval for the estimate of effect is wide, includes both clinically relevant benefit and harm and is of moderate quality).
Abstract: We included seven trials with a total of 435 participants. Three trials focused on Physalia (Bluebottle) jellyfish, one trial on Carukia jellyfish and three on Carybdea alata (Hawaiian box) jellyfish. Two ongoing trials were identified. Six of the seven trials were judged as having high risk of bias. Blinding was not feasible in four of the included trials because of the nature of the interventions. A wide range of interventions were assessed across trials, and a wide range of outcomes were measured. We reported results from the two trials for which data were available and reported the effects of interventions according to our definition of primary or secondary outcomes. Hot water immersion was superior to ice packs in achieving clinically significant (at least 50%) pain relief at 10 minutes (one trial, 96 participants, risk ratio (RR) 1.66, 95% confidence interval (CI) 1.01 to 2.72; low-quality evidence) and 20 minutes (one trial, 88 participants, RR 2.66, 95% CI 1.71 to 4.15; low-quality evidence). No statistically significant differences between hot water immersion and ice packs were demonstrated for dermatological outcomes. Treatment with vinegar or Adolph's meat tenderizer compared with hot water made skin appear worse (one trial, 25 participants, RR 0.31, 95% CI 0.14 to 0.72; low-quality evidence). Adverse events due to treatment were not reported in any trial. This review located a small number of trials that assessed a variety of different interventions applied in different ways and in different settings. Although heat appears to be an effective treatment for Physalia (Bluebottle) stings, this evidence is based on a single trial of low-quality evidence. It is still unclear what type of application, temperature, duration of treatment and type of water (salt or fresh) constitute the most effective treatment. In addition, these results may not apply to other species of jellyfish with different envenomation characteristics. Future research should further assess the most effective interventions using standardised research methodology.

Plain-language summary: This review identified seven trials on the treatment of jellyfish stings primarily involving two jellyfish species—Physalia (Bluebottle) and Carybdea alata (Hawaiian box) jellyfish—as well as two trials that are in progress. Many different types of treatments were tested in these trials. Large variation was observed between the duration of treatment among trials. Evidence of limited quality from a single study suggested that hot water immersion relieved pain. This evidence may not apply to other species of jellyfish because of large variability in the effects of stings. Further research should be conducted to help practitioners better understand the most effective treatments for jellyfish stings.
Abstract: We included four trials involving 543 women and their babies (but only data from 521 women and their babies is included in our analyses). Three of the four included studies had moderate to high risk of bias and one study was at low to moderate risk of bias. Babies born to women receiving management for borderline GDM (generally dietary counselling and metabolic monitoring) were less likely to be macrosomic (birthweight greater than 4000 g) (three trials, 438 infants, risk ratio (RR) 0.38, 95% confidence interval (CI) 0.19 to 0.74) or large-for-gestational (LGA) age (three trials, 438 infants, RR 0.37, 95% CI 0.20 to 0.66) when compared with those born to women in the routine care group. There were no significant differences in rates of caesarean section (three trials, 509 women, RR 0.93, 95% CI 0.68 to 1.27) and operative vaginal birth (one trial, 83 women, RR 1.37, 95% CI 0.20 to 9.27) between the two groups. This review found interventions including providing dietary advice and blood glucose level monitoring for women with pregnancy hyperglycaemia not meeting GDM and T2DM diagnostic criteria helped reduce the number of macrosomic and LGA babies without increasing caesarean section and operative vaginal birth rates. It is important to notice that the results of this review were based on four small randomised trials with moderate to high risk of bias without follow-up outcomes for both women and their babies.

Plain-language summary: This review found dietary advice or counselling and blood glucose level monitoring for women with borderline GDM helped reduce the number of macrosomic and LGA babies. A single trial found that the interventions led to more inductions of labour. The interventions did not increase the risk of caesarean sections, operative vaginal births or women's weight gain in pregnancy. These findings were based on four small randomised controlled trials (involving 543 women). The trials were of moderate to high risk of bias and only data from 521 women and their babies is included in our analyses. Until additional evidence from large well designed randomised trials becomes available, current evidence is insufficient to make conclusive recommendations for the management of women with pregnancy high blood glucose concentrations not meeting GDM (or type 2 diabetes) diagnostic criteria.
Abstract: Thirty-six trials involving 1718 people met the inclusion criteria. Study quality was mixed. Compared with control, CPAP showed significant improvements in certain objective and subjective sleepiness, measures of quality of life and cognitive function (parallel-group studies: Epworth sleepiness scale (ESS) -3.83 units, 95% CI -4.57 to -3.09; crossover studies: ESS -1.84 units, 95% CI -2.57 to -1.11). Twenty-four hour systolic and diastolic blood pressures were lower with CPAP compared with control (parallel-group trials). Compared with oral appliances, CPAP significantly reduced the apnoea and hypopnoea index (crossover studies: -7.97 events/hr, 95% CI -9.56 to -6.38) and improved sleep efficiency (crossover studies: 2.31%, 95% CI 0.02 to 4.6) and minimum oxygen saturation (4.14%, 95% CI 3.25 to 5.03). Responders to both treatments expressed a strong preference for the oral appliance. However, participants were more likely to withdraw on OA than on CPAP therapy. CPAP is effective in reducing symptoms of sleepiness and improving quality of life measures in people with moderate and severe obstructive sleep apnoea (OSA). It is more effective than oral appliances in reducing respiratory disturbances in these people but subjective outcomes are more equivocal. Certain people tend to prefer oral appliances to CPAP where both are effective. This could be because they offer a more convenient way of controlling OSA. Short-term data indicate that CPAP leads to lower blood pressure than control. Long-term data are required for all outcomes in order to determine whether the initial benefits seen in short-term clinical trials persist.

Plain-language summary: We searched and reviewed all randomised controlled trials that had been undertaken to evaluate the benefit of CPAP in adult patients with sleep apnoea. Some of the trials had methodological flaws, although more recent studies have begun to use appropriate forms of control. The overall results demonstrate that in people with moderate to severe sleep apnoea CPAP can improve measures of sleepiness, quality of life and associated daytime sleepiness. CPAP leads to lower blood pressure compared with control, although the degree to which this is achieved may depend upon whether people start treatment with raised blood pressures. Oral appliances are also used to treat sleep apnoea but, whilst some people find them more convenient to use than CPAP, they do not appear to be as effective at keeping the airway open at night. Further good quality trials are needed to define who benefits, by how much and at what cost. Further trials are also needed to evaluate the effectiveness of CPAP in comparison to other interventions, particularly those targeted at obesity.
Abstract: Fourteen eligible trials, which recruited patients between 1974 and 2005, were identified, eight of which compared 'more' with 'less' chemotherapy. Results from these eight trials, including 1519 patients, showed that treatment consisting of 'more' chemotherapy was associated with longer overall survival (OS) (hazard ratio (HR) 0.86; 95% confidence intervals (CI) 0.77 to 0.96; P = 0.005) and with longer progression-free survival (PFS) (n = 1526; HR 0.82; 95% CI 0.74 to 0.90; P < 0.0001). However, serious acute toxicities were more common in women randomised to the more-intense chemotherapy regimens. There was no evidence to suggest that any particular doublet chemotherapy was better (or worse) than any other, or that any single-agent chemotherapy was better (or worse) than another; however, data for these two comparisons were limited. There were no comparative trials of chemotherapy with endocrine therapy or best supportive care alone. This review suggests that more-intense chemotherapy regimens may improve both OS and PFS for women with advanced or recurrent endometrial cancer. However, owing to inconsistencies between cytotoxic drug combinations that have been assessed in randomised trials to date, the optimum regimen has still to be defined. Future trials should aim to include measures of quality of life (QoL) and symptom control in addition to survival and progression outcomes.

Plain-language summary: Using more chemotherapy drugs in combination seems to help women with advanced or recurrent endometrial cancer to live for longer and to delay the cancer from spreading or getting worse. However, giving these extra drugs may cause more serious short-term side effects. We do not know what effect using more drugs has on long-term side effects, control of symptoms or quality of life because they were poorly studied in the individual trials included in this review.
Abstract: Five trials involving 213 women were included.   Behavioural intervention vs control: One trial of pain management training reported reduction in pain and symptoms compared to a control. Three trials of relaxation compared to control reported varied results, two trials showed no difference in symptom severity scores however one trial reported relaxation was effective for reducing symptoms in menstrual sufferers with spasmodic symptoms. Two trials reported less restriction in daily activities following treatment with either relaxation of pain management training compared to a control. One trial also reported less time absent from school following treatment wit pain management training compared to a control. Behavioural intervention vs other behavioural interventions: Three trials showed no difference between behavioural interventions for the outcome of improvement in symptoms. One trial showed that relaxation resulted in a decrease in the need for resting time compared to the relaxation and imagery. There is some evidence from five RCTs that behavioural interventions may be effective for dysmenorrhoea. However results should be viewed with caution as they varied greatly between trials due to inconsistency in the reporting of data, small trial size, poor methodological quality and age of the trials.

Plain-language summary: This review found that progressive muscle relaxation with or without imagery and relaxation may help with spasmodic (acute, cramping pain) symptoms of period pain. Also that pain management training and relaxation plus biofeedback may help with period pain in general. The results are not conclusive due to the small number of women in the trials and the poor methods used in some of the trials.
Abstract: Our search did not yield any trial investigating treatment of VVC in HIV positive women. Two trials dealing with prophylaxis were eligible for inclusion.One trial (n= 323) favoured the use of weekly Fluconazole as compared to placebo (RR 0.68; 95% CI 0.47 to 0.97). The second trial with three arms of comparison; Clotrimazole, Lactobacillus and Placebo gave no definitive results in preventing an episode of VVC. Clotrimazole against placebo (RR 0.49; 95% CI 0.22 to 1.09), Clotrimazole against lactobacillus (RR 1.11; 95% CI 0.45 to 2.76) and lactobacillus against placebo (RR 0.54 ;95% CI 0.26 to 1.13). Implications for practice No trials were found addressing treatment of VVC in HIV positive women.In comparison to placebo,Fluconazole was found to be an effective preventative intervention. However, the potential for resistant Candida organisms to develop might impact the feasibility of implementation. Direction of findings suggests that Clotrimazole and Lactobacillus improved the prophylactic outcomes when compared to placebo. Implications for research  There is a need to evaluate drugs and drug regimens for VVC treatment and prophylaxis in HIV positive women through randomised clinical trials. Development of resistance to azoles remains under-studied and more work must be done in this area, so as to determine whether routine prophylaxis for VVC is at all needed or whether adequate ART would be sufficient to prevent recurrent VVC. The viral load in vaginal secretions with or without treatment or prophylaxis has not been studied, this is very relevant to the spread of HIV.

Plain-language summary: The search yielded two studies dealing with the preventive aspect of the condition. The first trial found weekly fluconazole significantly effective in preventing clinical episodes from occurring as compared to placebo. However,this regimen lead to emergence of species resistant to azoles. The second trial with three arms of comparison; Clotrimazole, Lactobacillus and placebo gave no definitive results in preventing an episode of VVC. Neither of the included studies investigated the effects of HAART(Highly Active Antiretroviral Therapy) or any other form of antiretroviral treatment on VVC nor did they explore difference in quality of life, viral shedding in vaginal secretions (infectivity) ,patient preference for route of administration or the cost.
Abstract: We found three RCTs involving 1815 men. Adjuvant RT following prostatectomy did not affect overall survival at 5 years (RD (risk difference) 0.00; 95% CI -0.03 to 0.03), but improved survival at 10 years (RD -0.11; 95% CI -0.20 to -0.02). Adjuvant RT did not improve prostate cancer-specific mortality at 5 years (RD -0.01; 95% CI -0.03 to 0.00). Adjuvant RT did not reduce metastatic disease at 5 years (RD -0.00; 95% CI -0.04 to 0.03), but reduced it at 10 years (RD -0.11; 95% CI -0.20 to -0.01). It improved local control at 5 and 10 years (RD -0.10; 95% CI -0.13 to -0.06 and RD -0.14; 95% CI -0.21 to -0.07, respectively), and biochemical progression-free survival at 5 years and 10 years (RD -0.16; 95% CI -0.21 to -0.11 and RD -0.29; 95% CI -0.39 to -0.19, respectively). There were no data for clinical disease-free survival. Adjuvant RT increased acute and late gastrointestinal toxicity [do you have the rd for this?], urinary stricture (RD 0.05; 95% CI 0.01 to 0.09) and incontinence (RD 0.04; 95% CI 0.01 to 0.08). It did not increase erectile dysfunction or degrade quality of life (RD 0.01; 95% CI -0.06 to -0.26), but with limited data. Adjuvant RT after RP improves overall survival and reduces the rate of distant metastases, but these effects are only evident with longer follow up. At 5 and 10 years it improves local control and reduces the risk of biochemical failure, although the latter is not a clinical endpoint. Moderate or severe acute and late toxicity is minimal. There is an increased risk of urinary stricture and incontinence, but no detriment to quality of life, based on limited data. Given that the majority of men who have undergone a RP have a longer life expectancy, radiotherapy should be considered for those with high-risk features following radical prostatectomy. The optimal timing is unclear.

Plain-language summary: One trial with longer follow up (more than 10 years) showed improved survival with adjuvant radiotherapy but this improvement did not exist at 5 years follow up. Radiotherapy reduced the number of men whose cancer spread to other parts of the body (metastases). We found that radiotherapy improved local control in the prostate bed and did reduce the risk of cancer recurring. Radiotherapy reduced the number of men with an abnormal PSA blood test, but the importance of this is uncertain. Radiotherapy does increase the risk of side effects, (mostly mild) affecting bladder and bowel function. It is not clear from these studies whether it is better to give radiotherapy immediately after surgery when these high risk features are present, or whether it would be just as good watching for a time, and only giving radiotherapy once the PSA blood test starts to rise. This is the subject of ongoing studies. Radiotherapy after radical prostatectomy should be considered if high risk features are present, but the optimal timing is unclear.
Abstract: Two trials of moderate quality in children (n = 134) with no evidence of airflow restriction did not find any benefits from oral beta2-agonists. Five trials in adults (n = 418) had mixed results but overall summary statistics did not reveal any significant benefits from oral (three trials) nor from inhaled (two trials) beta2-agonists. Three studies with low-quality evidence demonstrated no significant differences in daily cough scores, nor in the percentage of adults still coughing after seven days (control group 71%; risk ratio (RR) 0.86, 95% confidence interval (CI) 0.63 to 1.18; 220 participants). In one trial, subgroups with evidence of airflow limitation had lower symptom scores if given beta2-agonists. The trials that noted quicker resolution of cough with beta2-agonists were those with a higher proportion of people wheezing at baseline. Low-quality evidence suggests that adults given beta2-agonists were more likely to report tremor, shakiness or nervousness (RR 7.94, 95% CI 1.17 to 53.94; 211 participants; number needed to treat for an additional harmful outcome (NNTH) 2). There is no evidence to support the use of beta2-agonists in children with acute cough who do not have evidence of airflow restriction. There is also little evidence that the routine use of beta2-agonists is helpful for adults with acute cough. These agents may reduce symptoms, including cough, in people with evidence of airflow restriction. However, this potential benefit is not well supported by the available data and must be weighed against the adverse effects associated with their use.

Plain-language summary: Our searches are current to May 2015. We found no new trials. In previous searches, we found seven randomised controlled trials that used beta2-agonist drugs for people with acute bronchitis. Two trials studied children aged one to 10 years (134 participants) and five were conducted in adults (418 participants). None of the studies reported receiving grants from drug-making companies to conduct the study, but people who work for a drug maker were listed as authors on reports from two trials and study drugs were supplied free of charge by the company in three trials. Daily cough scores were no different between children given oral beta2-agonists and children in the placebo control groups. Daily cough scores, or the number of people still coughing after seven days, did not change in the adult trials either. However, the results were mixed. Some trials show a benefit and some show no benefit. This may be because some participants also had wheezing or other signs of narrowed airways, in which case beta2-agonists may be helpful only for them. More of the adults taking beta2-agonists had tremor, shakiness or nervousness. We rated this as low or moderate. There were few trials, with small numbers of people with acute bronchitis or cough. The trials were of short duration (three to seven days) and only two used inhaled beta2-agonists, which is now the usual way the drug is taken by adults and older children. Some important information about how the trial was done was not mentioned in the papers giving results for many of the trials.
