The clinical management of intermittent exotropia (X(T)) has been discussed extensively in the literature, yet there remains a lack of clarity regarding indications for intervention, the most effective form of treatment, and whether there is an optimal time in the evolution of the disease at which any given treatment should be carried out. ⋯ Patching confers a clinical benefit in children aged 12 months to 10 years of age with basic- or distance-type X(T) compared with active observation. There is insufficient evidence to determine whether interventions such as bilateral lateral rectus recession versus unilateral lateral rectus recession with medial rectus resection; lateral rectus recession and medial rectus plication versus lateral rectus recession and medial rectus resection; and prism adaptation test prior to eye muscle surgery versus eye muscle surgery alone may confer any benefit.

ReviewPhysiological track-and-trigger/early warning systems for use in maternity care.
A considerable challenge for maternity care providers is recognising clinical deterioration early in pregnant women. Professional bodies recommend the use of clinical assessment protocols or evaluation tools, commonly referred to as physiological track-and-trigger systems (TTS) or early warning systems (EWS), as a means of helping maternity care providers recognise actual or potential clinical deterioration early. TTS/EWS are clinician-administered (midwife, obstetrician), bedside physiological assessment protocols, charts or tools designed to record routinely assessed clinical parameters; that is, blood pressure, temperature, heart rate, urine output and mental/neurological alertness. In general, these systems involve the application of scores or alert indicators to the observed physiological parameters based on their prespecified limits of normality. The overall system score or alert limit is then used to assist the maternity care provider identify a need to escalate care. This, in turn, may allow for earlier intervention(s) to alter the course of the emerging critical illness and ultimately reduce or avoid mortality and morbidity sequelae. ⋯ We included two studies, a parallel RCT involving 700 women and a stepped-wedge cluster trial involving 536,233 women. Both studies were published in 2019, and both were conducted in low-resource settings. The interventions were the 'Saving Mothers Score' (SMS) and the CRADLE Vital Sign Alert (VSA) device, and both interventions were compared with standard care. Both studies had low or unclear risk of bias on all seven risk of bias criteria. Evidence certainty, assessed using GRADE, ranged from very low to moderate certainty, mainly due to other bias as well as inconsistency and imprecision. For women randomised to TTS/EWS compared to standard care there is probably little to no difference in maternal death (OR 0.80, 95% CI 0.30 to 2.11; 1 study, 536,233 participants; moderate-certainty evidence). Use of TTS/EWS compared to standard care may reduce total haemorrhage (OR 0.36, 95% CI 0.19 to 0.69; 1 study, 700 participants; low-certainty evidence). For women randomised to TTS/EWS compared to standard care there may be little to no difference in sepsis (OR 0.21, 95% CI 0.02 to 1.80; 1 study, 700 participants; low-certainty evidence), eclampsia (OR 1.50, 95% CI 0.74 to 3.03; 2 studies, 536,933 participants; low-certainty evidence) and HELLP (OR 0.21, 95% CI 0.01 to 4.40; 1 study, 700 participants; very low-certainty evidence), and probably little to no difference in maternal admission to the intensive care unit (ICU) (OR 0.78, 95% CI 0.53 to 1.15; 2 studies, 536,933 participants; moderate-certainty evidence). Use of TTS/EWS compared to standard care may reduce a woman's length of hospital stay (MD -1.21, 95% CI -1.78 to -0.64; 1 study, 700 participants; low-certainty evidence) but may result in little to no difference in neonatal death (OR 1.06, 95% CI 0.62 to 1.84; 1 study, 700 participants; low-certainty evidence). Cost-effectiveness measures were not measured in either of the two studies. AUTHORS' CONCLUSIONS: Use of TTS/EWS in maternity care may be helpful in reducing some maternal outcomes such as haemorrhage and maternal length of hospital stay, possibly through early identification of clinical deterioration and escalation of care. The evidence suggests that the use of TTS/EWS compared to standard care probably results in little to no difference in maternal death and may result in little to no difference in neonatal death. Both of the included studies were conducted in low-resource settings where the use of TTS/EWS might potentially confer a different effect to TTS/EWS use in high-resource settings. Further high-quality trials in high- and middle-resource settings, as well as in discrete populations of high- and low-risk women, are required.

ReviewPostoperative adjuvant chemotherapy for resectable cholangiocarcinoma.
Cholangiocarcinoma (cancer in the bile duct) is an aggressive tumour for which surgical resection is a mainstay of treatment. Despite complete resection, recurrences of the cancer are common and lead to poor prognosis in patients. Postoperative adjuvant chemotherapy given after surgical resection may reduce the risk of cancer recurrence by eradicating residual cancer and micrometastatic lesions. The benefits and harms of postoperative adjuvant chemotherapy versus placebo, no intervention, or other adjuvant chemotherapies are unclear. ⋯ Based on the very low-certainty evidence found in four trials in people with curative-intent resection for cholangiocarcinoma, we are very uncertain of the effects of postoperative adjuvant chemotherapy (mitomycin-C and 5-FU; gemcitabine; gemcitabine plus oxaliplatin; or capecitabine) versus no postoperative adjuvant chemotherapy on mortality. The effects of postoperative adjuvant chemotherapy compared with no postoperative adjuvant chemotherapy on serious adverse events are also very uncertain, but the result of the single trial showed 20% higher occurrences of haematologic adverse events. We assessed the certainty of the evidence as very low due to overall high risk of bias, and imprecision. Due to insufficient power of the only identified trial, the best postoperative adjuvant chemotherapy regimen in people with only cholangiocarcinoma could not be established. We also lack randomised clinical trials with outcome data on adjuvant S-1 chemotherapy versus adjuvant gemcitabine-based chemotherapy in people with cholangiocarcinoma alone. There is a need for further randomised clinical trials designed to be at low risk of bias and with adequate sample size exploring the best adjuvant chemotherapy treatment after surgery in people with cholangiocarcinoma.

ReviewKetamine and other glutamate receptor modulators for depression in adults with unipolar major depressive disorder.
Many studies have recently been conducted to assess the antidepressant efficacy of glutamate modification in mood disorders. This is an update of a review first published in 2015 focusing on the use of glutamate receptor modulators in unipolar depression. ⋯ Our findings show that ketamine and esketamine may be more efficacious than placebo at 24 hours. How these findings translate into clinical practice, however, is not entirely clear. The evidence for use of the remaining glutamate receptor modulators is limited as very few trials were included in the meta-analyses for each comparison and the majority of comparisons included only one study. Long term non-inferiority RCTs comparing repeated ketamine and esketamine, and rigorous real-world monitoring are needed to establish comprehensive data on safety and efficacy.

Review Meta AnalysisSingle-dose intravenous ibuprofen for acute postoperative pain in adults.
Postoperative administration of non-steroidal anti-inflammatory drugs (NSAIDs) reduces patient opioid requirements and, in turn, may reduce the incidence and severity of opioid-induced adverse events (AEs). ⋯ There is insufficient evidence to support or refute the suggestion that IV ibuprofen is effective and safe for acute postoperative pain in adults.
