Dietary supplement for mood symptoms in early postpartum: a double-blind randomized placebo controlled trial.

Background: Postpartum blues (PPB) is a frequent syndrome of sad mood, crying spells, anxiety, restlessness, reduced appetite, and irritability, typically peaking day 5 postpartum. When severe, it greatly increases risk for later postpartum depression. This trial compared a dietary supplement to placebo on PPB severity. The supplement was designed to counter downstream effects of elevated monoamine oxidase A level, implicated in causing PPB. Methods: Participants recruited by advertisement from the Toronto region completed procedures at CAMH, Canada and/or participants' homes. Oral supplement or identical appearing relatively inert placebo were administered in randomised, double-blind fashion. Supplement was blueberry juice and extract given four times between nighttime day 3 and morning day 5 postpartum; tryptophan 2 g nighttime day 4 postpartum, and tyrosine 10 g morning day 5 postpartum. On day 5, depressed mood induction procedure (MIP) and postpartum blues were assessed. All data is presented (NCT03296956 closed, clinicaltrials.gov). Findings: Between January 2019 and December 2022, participants took supplement (n = 51) or placebo (n = 52). There was no significant effect on primary outcome MIP on visual analogue scale for depressed mood (mean difference = -0.39 mm, 95% CI: -6.42 to 5.65 mm). Stein Maternity Blues scores, exploratory PPB measure, was lower in the active group (effect size 0.62; median, interquartile range (IQR): active 2.00 (IQR 1, 4); placebo 4.00 (IQR 1.5, 6); regression with general linear model, supplement effect, ß coefficient = -1.50 (95%: CI -2.60, -0.40), p = 0.008; effect of CES-D crying category before supplement, p = 0.03-0.00000023). Twenty-six and 40 different adverse events occurred within 25% and 42% of supplement and placebo cases respectively (Chi-Square, p = 0.06). Interpretation: The primary outcome was negative for effect on depressed mood induction, however the supplement moderately reduced PPB. Funding: CAMH/Exeltis.

Effectiveness of Emergency versus Nonemergent Coronary Angiography After Out-of-Hospital Cardiac Arrest without ST-Segment Elevation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

The optimal timing of coronary angiography (CAG) in patients after out-of-hospital cardiac arrest (OHCA) without ST-segment elevation remains controversial. Therefore, we conducted a meta-analysis of randomized control trials to investigate the effectiveness of emergency CAG versus delayed CAG in OHCA patients with a non-ST-segment elevated rhythm. PubMed, Scopus, CINAHL, Cochrane CENTRAL, and JBI databases were searched from inception to September 7, 2022. Our primary end point was survival with a good neurological outcome, whereas the secondary outcomes included short-term survival, mid-term survival, recurrent arrhythmias, myocardial infarction after hospitalization, major bleeding, acute kidney injury, and left ventricular ejection fraction. Nine randomized control trials involving 2,569 patients were included in this analysis. Our meta-analysis showed no significant difference in the improvement of neurological outcome (RR 0.96, 95% Confidence Interval [CI] [0.87, 1.06]), short-term survival (risk ratio [RR] 0.98, 95% CI [0.89, 1.08]), mid-term survival (RR 0.98, 95% CI [0.87, 1.10]), recurrent arrhythmias (RR 1.02, 95% CI [0.50, 2.06]), myocardial infarction (RR 0.66, 95% CI [0.13, 3.30]), major bleeding (RR 0.96, 95% CI [0.55, 1.69]), acute kidney injury (RR 1.20, 95% CI [0.32, 4.49]) and left ventricular ejection fraction (RR 0.89, 95% CI [0.69, 1.15]) in patients who underwent emergency CAG compared with delayed CAG patients. In conclusion, our analysis revealed that emergency CAG had no prognostic superiority over delayed CAG in patients with OHCA without ST-segment elevation.

Dengue surge in Pakistan amidst the torrential rains: The threat of a potential outbreak.

With 390 million infections occurring globally and the infection putting half of the world's population at risk, dengue is an illness with potential, life-threatening manifestations such as plasma leakage and fluid retention, severe bleeding, and organ impairment. This disease is already lurking in the various regions of Pakistan, which was recently ravaged by decades' worst flood. With mosquitoes being its eminent transmission source, it is coherent that a country with massive flooding, accumulation of stagnant water, and lack of adequate drainage systems can lead to a dengue outbreak. Pakistan, a low-middle-income country, is still recuperating from the aftershocks of the pandemic, a recent cholera outbreak, and the massive economic destruction they caused, especially in the healthcare sector. Concerningly, the World Health Organization has already issued a "second catastrophe" warning for Pakistan in the aftermath of the fatal floods which have caused the destruction of hundreds of health facilities while physicians and medical workers on the ground scramble to combat outbreaks of waterborne and other illnesses. If the spread of dengue isn't contained immediately, it will destroy the healthcare systems across the country and result in massive fatalities. To avoid tragic consequences, the government and concerned authorities must devise plans to launch public health programs aimed at boosting knowledge of the disease, its symptoms, transmission, prevention, and control. In this commentary, we discuss the current spike of dengue virus, epidemiology, transmission patterns, and preventative efforts in the aftermath of Pakistan's disastrous floods.
