BACKGROUND
Management of vasospastic and vaso-occlusive disorders is a complex challenge, with current treatments showing varied success. Cannabinoids have demonstrated both vasodilatory and antifibrotic properties, which present potential mechanisms for therapeutic relief. No existing review examines these effects in peripheral circulation in relation to vasospastic and vaso-occlusive disorders. This study aims to investigate vasodilatory and antifibrotic properties of cannabinoids in peripheral vasculature for application in vasospastic and vaso-occlusive disorders affecting the hand.
METHODS
A systematic search was conducted by 2 independent reviewers across PubMed, Cochrane, Ovid MEDLINE, and CINAHL to identify studies in accordance with the determined inclusion/exclusion criteria. Information regarding study design, medication, dosage, and hemodynamic or antifibrotic effects were extracted. Descriptive statistics were used to summarize study findings as appropriate.
RESULTS
A total of 584 articles were identified, and 32 were selected for inclusion. Studies were grouped by effect type: hemodynamic (n = 17, 53%) and antifibrotic (n = 15, 47%). Vasodilatory effects including reduced perfusion pressure, increased functional capillary density, inhibition of vessel contraction, and increased blood flow were reported in 82% of studies. Antifibrotic effects including reduced dermal thickening, reduced collagen synthesis, and reduced fibroblast migration were reported in 100% of studies.
CONCLUSION
Overall, cannabinoids were found to have vasodilatory and antifibrotic effects on peripheral circulation via both endothelium-dependent and independent mechanisms. Our review suggests the applicability of cannabis-based medicines for vasospastic and vaso-occlusive disorders affecting the hand (eg, Raynaud disease, Buerger disease). Future research should aim to assess the effectiveness of cannabis-based medicines for these conditions.

Review
BACKGROUND
According to current guidelines, initial burn resuscitation should be performed with fluids alone. The aims of the study were to review the frequency of use of vasoactive and/or inotropic drugs in initial burn resuscitation, and assess the benefits and harms of adding such drugs to fluids.
METHODS
A systematic literature search was conducted in PubMed, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, UpToDate, and SveMed+ through 3 December 2021. The search included studies on critically ill burn patients receiving vasoactive and/or inotropic drugs in addition to fluids within 48 h after burn injury.
RESULTS
The literature search identified 1058 unique publications that were screened for inclusion. After assessing 115 publications in full text, only two retrospective cohort studies were included. One study found that 16 out of 52 (31%) patients received vasopressor(s). Factors associated with vasopressor use were increasing age, burn depth, and % total body surface area (TBSA) burnt. Another study observed that 20 out of 111 (18%) patients received vasopressor(s). Vasopressor use was associated with increasing age, Baux score, and %TBSA burnt in addition to more frequent dialysis treatment and increased mortality. Study quality assessed by the Newcastle-Ottawa quality assessment scale was considered good in one study, but uncertain due to limited description of methods in the other.
CONCLUSION
This systematic review revealed that there is a lack of evidence regarding the benefits and harms of using vasoactive and/or inotropic drugs in addition to fluids during early resuscitation of patients with major burns.

BACKGROUND AND OBJECTIVE
Post-stroke constipation (PSC) is a common complication of strokes that seriously affects the recovery and quality of life of patients, and effective treatments are needed. Acupuncture is a viable treatment option, but current evidence is insufficient to support its efficacy and safety. This study aims to evaluate the efficacy and safety of acupuncture in the treatment of PSC.
METHODS
A systematic search of eight databases was conducted to identify PSC-related randomized clinical trials from the inception of each database through May 2023. Methodological quality assessment was conducted by RoB 2.0, meta-analysis was conducted by RevMan 5.3 and Stata 15.1, and evidence quality was evaluated by GRADE. Moreover, reporting quality of acupuncture interventions was assessed using the Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA).
RESULTS
Thirty RCTs involving 2,220 patients were identified. We found that acupuncture was superior to conventional treatment (CT) in improving total responder rate [risk ratio (): 1.16, 95% confidence interval (CI): 1.09 to 1.25, < 0.0001], decreasing constipation symptom scores [standardized mean difference (): -0.65, 95% CI: -0.83 to -0.46, < 0.00001], increasing serum P substance (SP) levels (: 1.92, 95% CI: 0.47 to 3.36, = 0.009), reducing the time to first bowel movement (BM) (: -1.19, 95% CI: -2.13 to -0.25, = 0.01), and lowing serum vasoactive intestinal peptide (VIP) levels (: -2.11, 95% CI: -3.83 to -0.38, = 0.02). Furthermore, acupuncture plus CT was superior regarding total responder rate (: 1.26, 95% CI: 1.17 to 1.35, < 0.00001), serum SP levels (: 2.00, 95% CI: 1.65-2.35, < 0.00001), time to first BM (: -2.08, 95% CI: -2.44 to -1.71, < 0.00001), and serum VIP levels (: -1.71, 95% CI: -2.24 to -1.18, < 0.00001). However, regarding Bristol Stool Scale (BSS) score, acupuncture plus CT was superior to CT (: -2.48, 95% CI: -3.22 to -1.73, < 0.00001), while there was no statistically significant difference between acupuncture and CT (: 0.28, 95% CI: -0.02 to 0.58, = 0.07). Acupuncture causes fewer AEs than CT (: 0.13, 95% CI: 0.06 to 0.26, < 0.00001), though there was no statistically significant difference between acupuncture plus CT vs. CT (: 1.30, 95% CI: 0.60 to 2.84, = 0.51).
CONCLUSION
Acupuncture may be an effective and safe therapy for PSC. However, given the inferior quality of clinical data, additional well-designed RCTs are required to confirm these findings.

Meta-Analysis
We conducted a systematic review and network meta-analyses evaluating the effects of different intraoperative vasoactive drugs on acute kidney injury (AKI) and other perioperative outcomes in adult liver transplant recipients. We searched multiple electronic databases using words from the "liver transplantation" and "vasoactive drug" domains. We included all randomized controlled trials conducted in adult liver transplant recipients comparing 2 different intravenous vasoactive drugs or 1 against a standard of care that reported AKI, intraoperative blood loss, or any other postoperative outcome. We conducted 4 frequentist network meta-analyses using random effect models, based on the interventions' mechanism of action, and evaluated the quality of evidence (QoE) using Grading of Recommendations, Assessment, Development, and Evaluations recommendations. We included 9 randomized controlled trials comparing different vasopressor drugs (vasoconstrictor or inotrope), 3 comparing a somatostatin infusion (or its analogues) to a standard of care, 11 comparing different vasodilator infusions together or against a standard of care, and 2 comparing vasoconstrictor boluses at graft reperfusion. Intravenous clonidine was associated with shorter duration of mechanical ventilation, intensive care unit, and hospital length of stay (very low QoE), and some vasodilators were associated with lower creatinine level 24 h after surgery (low to very low QoE). Phenylephrine and terlipressin were associated with less intraoperative blood loss when compared with norepinephrine (low and moderate QoE). None of the vasoactive drugs improve any other postoperative outcomes, including AKI. There is still important equipoise regarding the best vasoactive drug to use in liver transplantation for most outcomes. Further studies are required to better inform clinical practice.

Review
BACKGROUND
Laryngopharyngeal reflux-associated symptoms embrace a wide variety of head and neck manifestations. Its participation in eye disorders has recently been postulated, and there is currently no consensus in this regard. The aim of this manuscript is to review the role of reflux in the development of ocular signs and symptoms, and its physio-pathological mechanisms.
METHODS
A systematic approach based on the preferred reporting Items for a systematic review and meta-analysis checklist with a modified population, intervention, comparison, and outcome framework was used to structure the review process of studies that evaluated the possible association, with clear diagnostic methods, of laryngopharyngeal reflux and ocular signs and symptoms. Search was conducted in different indexed databases (PubMed/MEDLINE, the Cochrane Library, Scielo and Web of Science) and through the meta-searcher Trip Database with the keywords: reflux, laryngitis, laryngopharyngeal, gastroesophageal, ocular, eye, symptoms, signs, conjunctivitis, keratitis, dacryocystitis, dry eye.
RESULTS
Seven studies met the inclusion criteria, in which the primary acquired nasolacrimal duct obstruction and the ocular surface disease were evaluated. The local increase of eye pepsin concentration (>2.5 ng/mL) may affect ocular surface though its direct proteolytic activity and the local expression of proinflammatory cytokines. The H. Pylori, with a similar mechanism to reach the lacrimonasal duct, would be associated with the release of proinflammatory and vasoactive substances that would lead to a mucosa injury and chronic inflammation. Ocular Surface Disease Index seems to correlate directly with the reflux severity, with cut-off of 41.67 score as predictor for disease.
DISCUSSION
The role of laryngopharyngeal reflux in the development of ocular disorders has not yet been demonstrated and data are limited and heterogeneous. It seems theoretically conceivable that pepsin may reach lachrymal duct area through hypopharyngeal-nasal gaseous reflux events. Future studies using objective testing for diagnosis and pepsin detection into the tear and nasal mucosa are needed in order to explore this potential relationship.

Review
BACKGROUND
Cardiogenic shock (CS) is associated with high morbidity and mortality. In recent times, there is increasing interest in the role of angiotensin II in CS. We sought to systematically review the current literature on the use of angiotensin II in CS.
METHODS
PubMed, EMBASE, Medline, Web of Science, PubMed Central, and CINAHL databases were systematically searched for studies that evaluated the efficacy of angiotensin II in patients with CS during 01/01/2010-07/07/2022. Outcomes of interest included change in mean arterial pressure (MAP), vasoactive medication requirements (percent change in norepinephrine equivalent [NEE] dose), all-cause mortality, and adverse events.
RESULTS
Of the total 2,402 search results, 15 studies comprising 195 patients were included of which 156 (80%) received angiotensin II. Eleven patients (84.6%) in case reports and case series with reported MAP data at hour 12 noted an increase in MAP. Two studies noted a positive hemodynamic response (defined a priori) in eight (88.9%) and five (35.7%) patients. Eight studies reported a reduction in NEE dose at hour 12 after angiotensin II administration and one study noted a 100% reduction in NEE dose. Out of 47 patients with documented information, 13 patients had adverse outcomes which included hepatic injury (2), digital ischemia (1), ischemic optic neuropathy (1), ischemic colitis (2), agitated delirium (1), and thrombotic events (2).
CONCLUSIONS
In this first systematic review of angiotensin II in CS, we note the early clinical experience. Angiotensin II was associated with improvements in MAP, decrease in vasopressor requirements, and minimal reported adverse events.

Meta-Analysis
BACKGROUND
The optimisation of the use of β-lactam antibiotics (BLA) via prolonged infusions in life-threatening complications such as febrile neutropenia (FN) is still controversial. This systematic review and meta-analysis aim to evaluate the efficacy of this strategy in onco-haematological patients with FN.
METHODS
A systematic search was performed of PubMed, Web of Science, Cochrane, EMBASE, World Health Organization, and ClinicalTrials.gov, from database inception until December 2022. The search included randomised controlled trials (RCTs) and observational studies that compared prolonged vs short-term infusions of the same BLA. The primary outcome was all-cause mortality. Secondary outcomes were defervescence, requirement of vasoactive drugs, length of hospital stay and adverse events. Pooled risk ratios were calculated using random effects models.
RESULTS
Five studies were included, comprising 691 episodes of FN, mainly in haematological patients. Prolonged infusion was not associated with a reduction in all-cause mortality (pRR 0.83; 95% confidence interval 0.47-1.48). Nor differences were found in secondary outcomes.
CONCLUSIONS
The limited data available did not show significant differences in terms of all-cause mortality or significant secondary outcomes in patients with FN receiving BLA in prolonged vs. short-term infusion. High-quality RCTs are needed to determine whether there are subgroups of FN patients who would benefit from prolonged BLA infusion.

Meta-Analysis
OBJECTIVES
Pediatric delirium (PD) is a neuropsychiatric syndrome caused by a complex interplay between predisposing factors (e.g., age, cognitive impairment), acute illness, and environmental triggers. PD is associated with substantial morbidity and mortality. The objective of this study is to systematically review and evaluate factors associated with PD in hospitalized pediatric patients.
DATA SOURCES
A systematic search of PubMed, Embase, Ovid Medline, Web- of-Science, Cochrane, CIHNAL, and Google Scholar databases was conducted for relevant studies (1990-2022).
STUDY SELECTION
We included studies that compared pediatric patients with and without delirium. Reviews, editorials, congress abstracts, or studies that did not report factors for PD were excluded. No restrictions were imposed on language.
DATA EXTRACTION
Title and abstract were independently screened by two reviewers. Individual characteristics, study design, and outcomes were independently extracted.
DATA SYNTHESIS
Categorical dichotomous data were summarized across groups using Mantel-Haenszel odds ratios (ORs) with 95% 95% CIs. Either fixed-effect or random effects models were used as indicated by the results of a heterogeneity test. Of 1,846 abstracts, 24 studies were included. We identified 54 factors studied in univariate analyses, and 27 of these were associated with PD in multivariable analyses. In pooled analyses, greater odds of PD were associated with developmental delay (OR 3.98; 95% CI 1.54-10.26), need for mechanical ventilation (OR 6.02; 95% CI 4.43-8.19), use of physical restraints (OR 4.67; 95% CI 1.82-11.96), and receipt of either benzodiazepines (OR 4.10; 95% CI 2.48-6.80), opiates (OR 2.88; 95% CI 1.89-4.37), steroids (OR 2.02; 95% CI 1.47-2.77), or vasoactive medication (OR 3.68; 95% CI 1.17-11.60).
CONCLUSIONS
In this meta-analysis, we identified seven factors associated with greater odds of developing delirium during pediatric critical illness.

Meta-Analysis Review
BACKGROUND
The objective of this study is to conduct a systematic review and meta-analysis examining the relationship between the vasoactive-inotropic score (VIS) and patient outcomes in surgical settings.
METHODS
Two independent reviewers searched PubMed, Web of Science, EMBASE, Scopus, Cochrane Library, Google Scholar, and CNKI databases from November 2010, when the VIS was first published, to December 2022. Additional studies were identified through hand-searching the reference lists of included studies. Eligible studies were those published in English that evaluated the association between the VIS and short- or long-term patient outcomes in both pediatric and adult surgical patients. Meta-analysis was performed using RevMan Manager version 5.3, and quality assessment followed the Joanna Briggs Institute (JBI) Critical Appraisal Checklists.
RESULTS
A total of 58 studies comprising 29,920 patients were included in the systematic review, 34 of which were eligible for meta-analysis. Early postoperative VIS was found to be associated with prolonged mechanical ventilation (OR 5.20, 95% CI 3.78-7.16), mortality (OR 1.08, 95% CI 1.05-1.12), acute kidney injury (AKI) (OR 1.26, 95% CI 1.13-1.41), poor outcomes (OR 1.02, 95% CI 1.01-1.04), and length of stay (LOS) in the ICU (OR 3.50, 95% CI 2.25-5.44). The optimal cutoff value for the VIS as an outcome predictor varied between studies, ranging from 10 to 30.
CONCLUSION
Elevated early postoperative VIS is associated with various adverse outcomes, including acute kidney injury (AKI), mechanical ventilation duration, mortality, poor outcomes, and length of stay (LOS) in the ICU. Monitoring the VIS upon return to the Intensive Care Unit (ICU) could assist medical teams in risk stratification, targeted interventions, and parent counseling.

Meta-Analysis Review
OBJECTIVES
Cardiac surgery using cardiopulmonary bypass frequently provokes a systemic inflammatory response syndrome. This can lead to the development of low cardiac output syndrome (LCOS). Both of these can affect morbidity and mortality. This study is a systematic review of the impact of gaseous nitric oxide (gNO), delivered via the cardiopulmonary bypass (CPB) circuit during cardiac surgery, on post-operative outcomes. It aims to summarise the evidence available, to assess the effectiveness of gNO via the CPB circuit on outcomes, and highlight areas of further research needed to develop this hypothesis.
METHODS
A comprehensive search of Pubmed, Embase, Web of Science and the Cochrane Library was performed in May 2020. Only randomised control trials (RCTs) were considered.
RESULTS
Three studies were identified with a total of 274 patients. There was variation in the outcomes measures used across the studies. These studies demonstrate there is evidence that this intervention may contribute towards cardioprotection. Significant reductions in cardiac troponin I (cTnI) levels and lower vasoactive inotrope scores were seen in intervention groups. A high degree of heterogeneity between the studies exists. Meta-analysis of the duration of mechanical ventilation, length of ICU stay and length of hospital stay showed no significant differences.
CONCLUSION
This systematic review explored the findings of three pilot RCTs. Overall the hypothesis that NO delivered via the CPB circuit can provide cardioprotection has been supported by this study. There remains a significant gap in the evidence, further high-quality research is required in both the adult and paediatric populations.
