Meta-Analysis Review
BACKGROUND
Numerous prospective randomized clinical trials demonstrated favorable effect of beta-blockers in adults with chronic heart failure. However, effectiveness of beta blockers in pediatric patients with systemic ventricle systolic dysfunction was not recognized sufficiently. Limited number of pediatric patients might be the course of unrecognized carvediolol treatment benefit. Currently, no meta-analysis has examined the impact of carvedilol and conventional therapy on the clinical outcome in children with chronic heart failure due to impaired systemic ventricle systolic function.
MATERIALS AND METHODS
We have systematically searched the Medline/PubMed and Cochrane Library for the controlled clinical trials that examine carvedilol and standard treatment efficacy in pediatric patients with systemic ventricle systolic dysfunction. Mean differences for continuous variables, odds ratios for dichotomous outcomes, heterogeneity between studies and publication bias were calculated using Cochrane Review Manager (Rev Man 5.2).
RESULTS
Total of 8 prospective/observational studies met established criteria. Odds ratio for chronic heart failure related mortality/heart transplantation secondary to carvedilol was 0.52 (95% CI: 0.28-0.97, I(2) = 0%). Our analysis showed that carvedilol could prevent 1 death/ heart transplantation by treating 14 pediatric patients with impaired systemic ventricle systolic function.
CONCLUSION
Meta-analysis demonstrated clinical outcome benefit of carvedilol in children with chronic heart failure.

Meta-Analysis Review
BACKGROUND
Infantile hemangiomas (IHs) are a common pediatric lesion. Orally administered β-blockers have been reported as effective in treating these lesions. However, oral administration is also associated with systemic adverse effects. Treatment with locally administered β-blockers may provide acceptable efficacy with lower incidence of adverse effects. This may offer a better first-line treatment.
METHODS
PubMed was searched through March 2014 for studies reporting patient-level response of 5 or more patients treated with intralesional propranolol, topical timolol, or topical propranolol for cutaneous IHs. Rates of response to treatment, defined as clinically significant regression, were combined using random-effects meta-analysis.
RESULTS
Ninety-four articles were identified. Seventeen articles met the study criteria. These studies primarily focused on superficial IHs. Response rates for topical propranolol and topical timolol were not significantly different, 76% [95% confidence interval (CI), 62%-86%] and 83% (95% CI, 65%-93%), respectively (P=0.45). Prospectively conducted studies reported lower response rates compared to retrospective studies for both topical propranolol (P=0.06) and topical timolol (P<0.01). When only prospectively conducted studies were included, response rates for topical propranolol and topical timolol were not significantly different, 72% (95% CI, 57%-83%) and 72% (95% CI, 53%-86%), respectively (P=0.98). Significant adverse effects were rare. Only 1 case of sleep disturbance was reported across 554 patients from all studies.
CONCLUSIONS
Topically administered β-blockers are an effective treatment for superficial IHs that pose few adverse effects and should be considered for primary treatment.

The use of inhaled isopropyl alcohol (IPA) has been proposed as a therapeutic intervention for the relief of nausea in various settings. The objective of this systematic review was to evaluate the existing evidence for the use of inhaled IPA in the management of nausea and vomiting. We performed a literature search on Medline, EMBASE, Web of Science, Scopus, CINAHL, PsycInfo, and Cochrane Library databases before November 2021. The following concepts were searched using subject headings and keywords as needed "aromatherapy," "alcohol," "ethylic alcohol," "ethanol," "isopropyl alcohol," "emesis," "chemotherapy-induced," "pregnancy," "hyperemesis gravidarum," "motion sickness," "emetics," "antiemetics," "inhalation," and "inhale." Searches were not limited to a specific language. The bibliographies of identified articles were also manually searched. Two authors independently assessed the included studies for risk of bias. Thirteen randomized controlled trials out of 158 studies identified met the inclusion criteria, with a total of 1253 participants. Twelve studies were conducted in the postoperative anesthesia care unit and two studies were performed in the emergency department setting. Four studies were double blinded, one was single blind, and eight were open label. Three studies assessed the use of inhaled IPA for prevention, whereas 10 studies evaluated its use in the treatment of nausea and vomiting. Seven studies reported IPA to be more effective, four studies reported no difference, and two studies reported IPA to be ineffective. Participant satisfaction was high overall, regardless of intervention received. No adverse effects were reported. The overall quality of evidence was low. There is a lack of strong evidence to support the use of inhaled IPA in the management of nausea and vomiting. Additional trials are warranted to confirm this finding and to further explore the use of inhaled IPA in various populations and settings.

Review
BACKGROUND
Stroke affects 15 million people per year worldwide. Despite recent developments in acute stroke treatment, prevention remains very important. Stroke has a high rate of recurrence; therefore secondary prevention is also important. Many clinical approaches to control risk factors have been proposed. One of these approaches is the prescription of beta-blockers that have effects beyond the reduction of blood pressure, which can reduce the recurrence of stroke.
OBJECTIVES
To evaluate the efficacy of beta-blockers for preventing stroke recurrence and for reducing death and major vascular events in people with a previous stroke or transient ischaemic attack (TIA), and to determine their safety, particularly with regard to the development of diabetes mellitus.
SEARCH METHODS
We searched the Cochrane Stroke Group Trials Register (May 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Database of Systematic Reviews (CDSR) (The Cochrane Library 2014, Issue 5), the Database of Abstracts of Reviews of Effects (DARE) (May 2014), MEDLINE (1966 to May 2014), EMBASE (1980 to May 2014), and Latin American and Caribbean Health Sciences Literature (LILACS) (1982 to May 2014). We also searched ongoing trials registers and reference lists.
SELECTION CRITERIA
Randomised controlled trials (RCTs) that included participants with previous stroke or TIA due to arterial thrombosis or embolism. The intervention was any beta-blocker versus control, or beta-blocker plus other treatment versus other treatment.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the trials identified, appraised quality, and extracted data.
MAIN RESULTS
We included two RCTs involving 2193 participants in the review. Both studies randomised participants to either beta-blocker (atenolol 5 mg) or placebo and were of a high methodological quality. We noted no statistical differences among the groups in risks of fatal and non-fatal stroke (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.76 to 1.18). For other outcomes analysed (major vascular events, death from all causes, death from cardiovascular causes) , we observed no significant differences between the groups. There were minor blood pressure reductions in the intervention group. Neither of the included studies reported the occurrence of diabetes among their outcomes or assessed quality of life. Adverse events were significantly more frequent in participants taking atenolol than in those given placebo, and were the most common reason given for discontinuing treatment (RR 1.85, 95% CI 1.45 to 2.35).
AUTHORS' CONCLUSIONS
To date, no available evidence supports the routine use of beta-blockers for secondary prevention after stroke or TIA. More studies with larger samples are needed.

Meta-Analysis
PURPOSE
β-adrenoceptor antagonist (β-blocker) may have potential in the treatment of septic shock and sepsis. However, the relevant research findings are still controversial.
METHODS
We conducted a systematic review and meta-analysis to explore the efficacy of β-blocker in patients with septic shock and sepsis. The primary sources of the reviewed studies through August 2018, with restriction on the language of English, were Pubmed and Embase. Randomized controlled trials (RCT) were included to evaluate the efficacy of β-blocker in the treatment of septic shock and sepsis. Meta analysis was performed using a random effect model. Two researchers independently searched articles, extracted data, and assessed the quality of the included studies.
RESULTS
A total of 6 studies related to 5 original RCTs were qualified for inclusion in this systematic review and meta-analysis with a total of 363 patients with sepsis and/or septic shock. β-blocker was associated with a significantly decreased 28-day mortality compared to usual treatment group as the control (RR = 0.59, 95%CI: 0.48, 0.74; P < 0.00001). Heart rate in β-blocker was significantly lower than that in the standard care group (SMD = -2.01, 95%CI: -3.03, -0.98; P = 0001).
CONCLUSION
β-blocker of esmolol is safe and effective in improving 28-day mortality and controlling ventricular rate in patients with sepsis after fluid resuscitation, and has no significant adverse effect on tissue perfusion.

Meta-Analysis
The efficacy of the fixed combination of latanoprost and timolol versus other fixed combinations for primary open-angle glaucoma and ocular hypertension: A systematic review and meta-analysis.
BACKGROUND
Fixed-combination (FC) therapy is used in primary open-angle glaucoma (POAG) and ocular hypertension (OHT) patients who require more than one medication to reach their target intraocular pressure (IOP). Currently, there are several FC therapies available for the treatment of glaucoma. The FC of latanoprost/timolol (LTFC) is a commonly used FC. Here, we conducted systematic review to compare the IOP-lowering effects of LTFC with other FCs for patients with POAG and OHT.
MATERIALS AND METHODS
We searched PubMed, EMBASE, the Cochrane Library, and Web of Science for randomized-controlled clinical trials and cross-over studies. The outcomes were mean IOP and IOP fluctuation after one month of treatment. Meta-analysis was carried out using RevMan (version 5.1) software. After conducting meta-analyses, we rated the quality of each meta-analysis as high, moderate, low, or very low using the "GRADE" system.
RESULTS
We included 16 trials in this meta-analysis. Moderate-quality meta-analysis showed that LTFC had a comparable mean IOP to that of a fixed combination of travoprost and timolol (TTFC) [mean difference (MD): 0.07 mmHg] and a fixed combination of dorzolamide and timolol (DTFC) [MD: -0.31 mmHg], and it also had a comparable IOP-fluctuation effect compared to that of TTFC [MD: 0.13 mm Hg] and DTFC [MD: 0.25 mmHg]. Compared to the fixed combination of bimatoprost and timolol (BiTFC), moderate-quality evidence showed a higher mean IOP in the LTFC group [MD 0.76 mmHg], whereas low-quality meta-analysis showed higher IOP fluctuation [MD 1.09 mmHg] in the LTFC group.
CONCLUSIONS
LTFC is as effective as TTFC and DTFC, but worse than BiTFC in controlling mean IOP and IOP fluctuation for POAG or OHT patients. The quality of our meta-analyses was assessed as moderate, with the exception of one low-quality analysis that compared the IOP fluctuation of LTFC and BiTFC.

Meta-Analysis
Systematic review and meta-analysis on the efficacy and tolerability of mirabegron for the treatment of storage lower urinary tract symptoms/overactive bladder: Comparison with placebo and tolterodine.
A systematic review and meta-analysis was carried out to evaluate the efficacy and safety of mirabegron 50 mg and 100 mg in the treatment of storage lower urinary tract symptoms/overactive bladder in comparison with a placebo and tolterodine 4 mg. A total of 491 articles were collected and eight randomized studies were identified as eligible for this meta-analysis. Overall, eight trials were included in the meta-analysis evaluating 10 248 patients. Mirabegron at both doses of 50 mg and 100 mg, and and tolterodine 4 mg were significantly associated with the reduction of incontinence episodes per 24 h, reduction of mean number of micturitions per 24 h, increase of voided volume and reduction of urgency episodes per 24 h, compared to a placebo. Both mirabegron 50 mg and mirabegron 100 mg were associated with a significant reduction of nocturia episodes when compared with a placebo. Conversely, tolterodine 4 mg did not prove to be more effective than a placebo in the reduction of nocturia episodes. Furthermore, mirabegron 50 mg showed a slightly, but significantly, better efficacy than tolterodine 4 mg in the improvement of nocturia episodes. Mirabegron 50 mg and mirabegron 100 mg shared the same risk of overall treatment-emergent adverse events rate with the placebo. Otherwise, tolterodine 4 mg was associated with a significantly greater risk than the placebo. However, mirabegron 100 mg showed a slight trend toward an increased risk of hypertension (odds ratio 1.41; P = 0.08) and cardiac arrhythmia (odds ratio 2.18; P = 0.06). Mirabegron is an effective treatment for patients with storage lower urinary tract symptoms/overactive bladder, providing a reduction of incontinence, urgency and frequency; an improvement of voided volume with a slight, but statistically, significant improvement of nocturia; with a good safety profile. These findings should be considered for the treatment planning of patients with storage lower urinary tract symptoms/overactive bladder.

Meta-Analysis Review
BACKGROUND
Dysmenorrhoea is a common gynaecological complaint that can affect as many as 50% of premenopausal women, 10% of whom suffer severely enough to be rendered incapacitated for one to three days during each menstrual cycle. Primary dysmenorrhoea is where women suffer from menstrual pain but lack any pathology in their pelvic anatomy. Beta2-adrenoceptor agonists have been used in the treatment of women with primary dysmenorrhoea but their effects are unclear.
OBJECTIVES
To determine the effectiveness and safety of beta2-adrenoceptor agonists in the treatment of primary dysmenorrhoea.
SEARCH METHODS
We searched the Cochrane Menstrual Disorders and Subfertility Group Specialised Register; CENTRAL (The Cochrane Library 2011, Issue 8); MEDLINE; EMBASE; PsycINFO and the EBM Reviews databases. The last search was on 22 August 2011.
SELECTION CRITERIA
Randomised controlled trials comparing beta2-adrenoceptor agonists with placebo or no treatment, each other or any other conventional treatment in women of reproductive age with primary dysmenorrhoea.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial quality and extracted the data.
MAIN RESULTS
Five trials involving 187 women with an age range of 15 to 40 years were included. Oral isoxsuprine was compared with placebo in two trials; terbutaline oral spray, ritodrine chloride and oral hydroxyphenyl-orciprenalin were compared with placebo in a further three trials. Clinical diversity in the studies in terms of the interventions being evaluated, assessments at different time points and the use of different assessment tools mitigated against pooling of outcome data across studies in order to provide a summary estimate of effect for any of the comparisons. Only one study, with unclear risk of bias, reported pain relief with a combination of isoxsuprine, acetaminophen and caffeine. None of the other studies reported any significant clinical difference in effectiveness between the intervention and placebo. Adverse effects were reported with all of these medications in up to a quarter of the total number of participants. They included nausea, vomiting, dizziness, quivering, tremor and palpitations.
AUTHORS' CONCLUSIONS
The evidence presented in this review was based on a few relatively small-sized studies that were categorised to have unclear to high risk of bias, which does not allow confident decision-making at present about the use of beta2-adrenoceptor agonists for dysmenorrhoea. The benefits as reported in one study should be balanced against the wide array of unacceptable side effects documented with this class of medication. We have emphasised the lack of precision and limitations in the reported data where appropriate.

Meta-Analysis Review
OBJECTIVES
The aim of the study is to compare the safety and efficacy of unilateral anterograde cerebral perfusion (UACP) and bilateral anterograde cerebral perfusion (BACP) for acute type A aortic dissection (ATAAD).
METHODS
A systematic review of the MEDLINE (PubMed), Scopus, and Cochrane Library databases (last search: August 7th, 2021) was performed according to the PRISMA statement. Studies directly comparing UACP versus BACP for ATAAD were included. Random-effects meta-analyses were performed.
RESULTS
Eight retrospective cohort studies were identified, incorporating 2416 patients (UACP: 843, BACP: 1573). No statistically significant difference was observed regarding in-hospital mortality (odds ratio [OR]:1.05 [95% Confidence Interval (95% CI):0.70-1.57]), permanent neurological deficit (PND) (OR: 0.94 [95% CI: 0.52-1.70]), transient neurological deficit (TND) (OR: 1.37 [95% CI: 0.98-1.92]), renal failure (OR: 0.96 [95% CI: 0.70-1.32]), and re-exploration for bleeding (OR: 0.77 [95% CI: 0.48-1.22]). Meta-regression analysis revealed that PND and TND were not influenced by differences in rates of total arch repair, Bentall procedure, and concomitant CABG in UACP and BACP groups. Cardiopulmonary bypass time (Standard Mean Difference [SMD]: -0.11 [95% CI: -0.22, 0.44]), Cross clamp time (SMD: -0.04 [95% CI: -0.38, 0.29]), and hypothermic circulatory arrest time (SMD: -0.12 [95% CI: -0.55, 0.30]) were comparable between UACP and BACP. Intensive care unit stay was shorter in BACP arm (SMD:0.16 [95% CI: 0.01, 0.31]); however, length of hospital stay was shorter in UACP arm (SMD: -0.25 [95% CI: -0.45, -0.06]).
CONCLUSIONS
UACP and BACP had similar results in terms of in-hospital mortality, PND, TND, renal failure, and re-exploration for bleeding rate in patients with ATAAD. ICU stay was shorter in the BACP arm while LOS was shorter in the UACP arm.

Comparative Study Meta-Analysis Review
PURPOSE
To estimate the intraocular pressure (IOP)-lowering effect of prostaglandin analogs (PGAs) administered in combination with β-blockers.
METHODS
We searched the Medline and Embase databases for randomized trials comparing topical therapies with PGAs and timolol administered as monotherapy (Mt), or in fixed (FC) or unfixed combinations (UC) to patients with glaucoma or ocular hypertension. The efficacy endpoint was the mean difference (MeD) in the reduction in IOP from baseline; the tolerability endpoint was the incidence of hyperemia.
RESULTS
The 18 eligible trials involved 23 comparisons of FC versus Mt, and 5 of FC versus UC. The FCs were less efficacious than UCs (MeD: 0.69, 95% CI: 0.29 to 1.08). In comparison with timolol Mt, the latanoprost/timolol FC led to a greater IOP reduction (MeD: -2.74, 95% CI: -3.24 to -2.23) than the bimatoprost/timolol FC (MeD: -1.49, 95% CI: -1.86 to -1.12) or the travoprost/timolol FC (MeD: -1.93, 95%CI: -2.98 to -0.88). The FCs led to a lower hyperemia risk than UCs [relative risk (RR): 0.70, 95% CI: 0.43 to 1.14] and PGA Mt (RR: 0.61, 95% CI: 0.53 to 0.70).
CONCLUSIONS
FCs are more efficacious than their individual components, but less efficacious than their respective UCs. FCs lead to a lower hyperemia risk than UCs and their respective PGA Mts.
