Comparative Study Meta-Analysis
To conduct a systematic literature review of high-risk resectable cutaneous melanoma adjuvant therapeutics and compare safety and efficacy. The systematic literature review included randomized controlled trials investigating: dabrafenib plus trametinib (DAB + TRAM), nivolumab, pembrolizumab, ipilimumab, vemurafenib, chemotherapy and interferons. Outcomes included overall survival (OS), relapse-free survival, distant metastasis-free survival and safety. All outcomes were synthesized using Bayesian network meta-analysis. Across relapse-free survival, distant metastasis-free survival and OS, DAB + TRAM had the lowest estimated hazards of respective events relative to all other treatments (exception relative to nivolumab in OS). Differences were significant relative to placebo, chemotherapy, interferons and ipilimumab. DAB + TRAM has improved efficacy over historical treatment options (ipilimumab, interferons and chemotherapy) and comparable efficacy with other targeted and immune checkpoint inhibitors.

Meta-Analysis
The objective was to systematically review the literature and assess the relative efficacy of agents approved in first-line settings via network meta-analysis. A literature review was conducted via searching different medical databases. The eligibility criteria included Phase II or III randomized controlled trials that had enrolled treatment-naive adult patients with advanced/metastatic melanoma. The network meta-analysis results suggested that dabrafenib + trametinib significantly prolongs the survival outcomes compared with the monotherapies and had comparable efficacy profile compared with encorafenib + binimetinib and cobimetinib + vemurafenib. In comparison with immunotherapies, the results varied for progression-free survival and overall survival. Long-term survival data of dabrafenib + trametinib establishes the combination as one of the preferred treatment options for previously untreated melanoma patients.

Disseminated intravascular coagulation is a complex and potentially lethal complication of malignancy, in which the fundamental abnormality is excessive activation of the coagulation system. It is a rare complication of melanoma which can be difficult to diagnose in some circumstances, leading to delay in treatment. Herein, we describe the first case of disseminated intravascular coagulation occurring in BRAF and NRAS-mutant metastatic melanoma, and systematically review the literature regarding disseminated intravascular coagulation in melanoma. This review summarizes the reported cases of disseminated intravascular coagulation in melanoma and those secondary to the novel treatment of melanoma, and explores the pathophysiology of disseminated intravascular coagulation in melanoma, highlighting the key role of expression of markers of coagulation and fibrinolysis in disseminated intravascular coagulation, as well as more widely in melanoma. Current limitations in the literature are also identified and discussed, particularly with respect to improving the management of this lethal complication. Disseminated intravascular coagulation is a rare complication of melanoma that typically portends poor prognosis.

Exploring the utility of RDoC in differentiating effectiveness amongst antidepressants: A systematic review using proposed psychometrics as the unit of analysis for the Negative Valence Systems domain.
BACKGROUND
RDoC conceptualises psychopathology as neurobiologically-rooted behavioural psychological "constructs" that span dimensionally from normality to pathology, but its clinical utility remains controversial.
AIM
To explore RDoC's potential clinical utility by examining antidepressant effectiveness through Negative Valence Systems (NVS) domain constructs.
METHOD
A systematic review was conducted on Web of Science, MEDLINE, EMBASE and PsycINFO for antidepressant trials that included psychometric instruments assessed by Watson, Stanton & Clark (2017) to represent NVS constructs of Acute Threat, Potential Threat and Loss.
RESULTS
221 citations were identified; 13 were included in qualitative synthesis, none for quantitative analysis. All suffered from significant bias risks. 9 antidepressants were investigated, most within 1 construct, and most were found to be effective. Paroxetine, citalopram and fluvoxamine were found to be effective for Acute Threat, fluoxetine, desvenlafaxine and sertraline for Potential Threat, and sertraline, fluvoxamine, fluoxetine and desvenlafaxine effective for Loss. Nefazodone was found to be ineffective for acute fear.
CONCLUSION
Preliminary evidence supports RDoC NVS constructs' clinical utility in assessing antidepressant effectiveness, but lack of discriminant validity between Potential Threat and Loss supports their recombination into a single Distress construct. Finding of effectiveness within "normal" construct levels support the utility of a dimensional approach. Testable hypotheses were generated that can further test RDoC's clinical utility.
