Review Meta AnalysisCalcium supplementation for prevention of primary hypertension.
Hypertension is a major public health problem that increases the risk of cardiovascular and kidney diseases. Several studies have shown an inverse association between calcium intake and blood pressure, as small reductions in blood pressure have been shown to produce rapid reductions in vascular disease risk even in individuals with normal blood pressure ranges. This is the first update of the review to evaluate the effect of calcium supplementation in normotensive individuals as a preventive health measure. ⋯ An increase in calcium intake slightly reduces both systolic and diastolic blood pressure in normotensive people, particularly in young people, suggesting a role in the prevention of hypertension. The effect across multiple prespecified subgroups and a possible dose response effect reinforce this conclusion. Even small reductions in blood pressure could have important health implications for reducing vascular disease. A 2 mmHg lower systolic blood pressure is predicted to produce about 10% lower stroke mortality and about 7% lower mortality from ischaemic heart disease. There is a great need for adequately-powered clinical trials randomising young people. Subgroup analysis should involve basal calcium intake, age, sex, basal blood pressure, and body mass index. We also require assessment of side effects, optimal doses and the best strategy to improve calcium intake.

Review Meta AnalysisChronic non-invasive ventilation for chronic obstructive pulmonary disease.
Chronic non-invasive ventilation (NIV) is increasingly being used to treat people with COPD who have respiratory failure, but the evidence supporting this treatment has been conflicting. ⋯ Regardless of the timing of initiation, chronic NIV improves daytime hypercapnia. In addition, in stable COPD, survival seems to be improved and there might be a short term HRQL benefit. In people with persistent hypercapnia after a COPD exacerbation, chronic NIV might prolong admission-free survival without a beneficial effect on HRQL. In stable COPD, future RCTs comparing NIV to a control group receiving standard care might no longer be warranted, but research should focus on identifying participant characteristics that would define treatment success. Furthermore, the optimal timing for initiation of NIV after a severe COPD exacerbation is still unknown.

Review Clinical TrialIndividual-level interventions to reduce personal exposure to outdoor air pollution and their effects on people with long-term respiratory conditions.
More than 90% of the global population lives in areas exceeding World Health Organization air quality limits. More than four million people each year are thought to die early due to air pollution, and poor air quality is thought to reduce an average European's life expectancy by one year. Individuals may be able to reduce health risks through interventions such as masks, behavioural changes and use of air quality alerts. To date, evidence is lacking about the efficacy and safety of such interventions for the general population and people with long-term respiratory conditions. This topic, and the review question relating to supporting evidence to avoid or lessen the effects of air pollution, emerged directly from a group of people with chronic obstructive pulmonary disease (COPD) in South London, UK. ⋯ The lack of evidence and study diversity has limited the conclusions of this review. Using a mask or a lower-pollution cycle route may mitigate some of the physiological impacts from air pollution, but evidence was very uncertain. We found conflicting results for other outcomes, including health care usage, symptoms and adherence/behaviour change. We did not find evidence for adverse events. Funders should consider commissioning larger, longer studies, using high-quality and well-described methods, recruiting participants with pre-existing respiratory conditions. Studies should report outcomes of importance to people with respiratory conditions, such as exacerbations, hospital admissions, quality of life and adverse events.

Kinesio Taping (KT) is one of the conservative treatments proposed for rotator cuff disease. KT is an elastic, adhesive, latex-free taping made from cotton, without active pharmacological agents. Clinicians have adopted it in the rehabilitation treatment of painful conditions, however, there is no firm evidence on its benefits. ⋯ Kinesio taping for rotator cuff disease has uncertain effects in terms of self-reported pain, function, pain on motion and active range of motion when compared to sham taping or other conservative treatments as the certainty of evidence was very low. Low-certainty evidence shows that kinesio taping may improve quality of life when compared to conservative treatment. We downgraded the evidence for indirectness due to differences among co-interventions, imprecision due to small number of participants across trials as well as selection bias, performance and detection bias. Evidence on adverse events was scarce and uncertain. Based upon the data in this review, the evidence for the efficacy of KT seems to demonstrate little or no benefit.

ReviewPosterior musculofascial reconstruction in robotic-assisted laparoscopic prostatectomy for the treatment of clinically localized prostate cancer.
Delayed recovery of urinary continence is a major adverse effect of robotic-assisted laparoscopic prostatectomy (RALP) in men undergoing prostate cancer treatment. To address this issue, a number of surgical techniques have been designed to reconstruct the posterior aspect of the rhabdosphincter, which is responsible for urinary continence after removal of the prostate; however, it is unclear how well they work. OBJECTIVES: To assess the effects of posterior musculofascial reconstruction RALP compared to no posterior reconstruction during RALP for the treatment of clinically localized prostate cancer. ⋯ Our search identified 13 records of eight unique RCTs, of which six were published studies and two were abstract proceedings. We included 1085 randomized participants, of whom 963 completed the trials (88.8%). All participants had either cT1c or cT2 or cT3a disease, with a mean prostate-specific antigen level of 8.15 ng/mL. Primary outcomes Posterior reconstruction RALP (PR-RALP) may improve urinary continence one week after catheter removal compared to no posterior reconstruction during RALP (risk ratio (RR) 1.25, 95% confidence interval (CI) 0.90 to 1.73; I2 = 42%; studies = 5, participants = 498; low CoE) although the CI also includes the possibility of no effect. Assuming 335 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 84 more men per 1000 (33 fewer to 244 more) reporting urinary continence recovery. Posterior reconstruction may have little to no effect on urinary continence three months after surgery compared to no posterior reconstruction during RALP (RR 0.98, 95% CI 0.84 to 1.14; I2 = 67%; studies = 6, participants = 842; low CoE). Assuming 701 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 14 fewer men per 1000 (112 fewer to 98 more) reporting urinary continence after three months. PR-RALP probably results in little to no difference in serious adverse events compared to no posterior reconstruction during RALP (RR 0.75, 95% CI 0.29 to 1.92; I2 = 0%; studies = 6, participants = 835; moderate CoE). Assuming 25 per 1000 men undergoing standard RALP experience a serious adverse event at this time point, this corresponds to six fewer men per 1000 (17 fewer to 23 more) reporting serious adverse events. Secondary outcomes PR-RALP may result in little to no difference in recovery of continence 12 months after surgery compared to no posterior reconstruction during RALP (RR 1.02, 95% CI 0.98 to 1.07; I2 = 25%; studies = 3, participants = 602; low CoE). Assuming 918 per 1000 men undergoing standard RALP are continent at this time point, this corresponds to 18 more men per 1000 (18 fewer to 64 more) reporting urinary continence recovery. We are very uncertain about the effects of PR-RALP on recovery of potency 12 months after surgery compared to no posterior reconstruction during RALP (RR 1.02, 95% CI 0.82 to 1.26; I2 = 3%; studies = 2, participants = 308; very low CoE). Assuming 433 per 1000 men undergoing standard RALP are potent at this time point, this corresponds to nine more men per 1000 (78 fewer to 113 more) reporting potency recovery. PR-RALP may result in little to no difference in positive surgical margins compared to no posterior reconstruction during RALP (RR 1.24, 95% CI 0.65 to 2.33; I2 = 50%; studies = 3, participants = 517; low CoE). Assuming 130 per 1000 men undergoing standard RALP have a positive surgical margin, this corresponds to 31 more men per 1000 (46 fewer to 173 more) reporting positive surgical margins. PR-RALP may result in little to no difference in biochemical recurrence compared to no posterior reconstruction during RALP (RR 1.36, 95% CI 0.74 to 2.52; I2 = 0%; studies = 2, participants = 468; low CoE). Assuming 70 per 1000 men undergoing standard RALP have experienced biochemical recurrence at this time point, this corresponds to 25 more men per 1000 (18 fewer to 107 more) reporting biochemical recurrence. AUTHORS' CONCLUSIONS: This review found evidence that PR-RALP may improve early continence one week after catheter removal but not thereafter. Meanwhile, adverse event rates are probably not impacted and surgical margins rates are likely similar. This review was unable to determine if or how these findings may be impacted by the person's age, nerve-sparing status, or clinical stage. Study limitations, imprecision, and inconsistency lowered the certainty of evidence for the outcomes assessed.
