Abstract
OBJECTIVES Bacille Calmette-Guérin (BCG) vaccination lowers the risk of severe infection; we tested whether effects are modulated by maternal BCG in a large cohort of BCG-vaccinated newborns from Guinea-Bissau. METHODS Maternal BCG scar status were inspected at enrolment in a BCG trial conducted from 2014-17 in Bissau, Guinea-Bissau. We tested associations with background factors for potential confounding; maternal age affected effect estimates >5% and accordingly, all analyses were adjusted for maternal age. Hospitalization data was collected prospectively and assessed in Cox-models providing adjusted Incidence Rate Ratios (aIRRs). In-hospital risk of death (case-fatality) risk was assessed using binomial regression providing adjusted Risk Ratios (aRRs). RESULTS 60% (6,309/10,598) of mothers had a scar. The maternal-scar/no-scar admission aIRR was 0.96 (0.81-1.14) from 0-6 weeks and 1.12 (0.97-1.28) for 6 weeks-3 years. The 6-week in-hospital case-fatality infection aRR was 0.59 (0.34-1.05); 0.40 (0.17-0.91) for males and 0.86 (0.38-1.94) for females. Protection was especially evident against sepsis, the overall 6-week aRR=0.49 (0.26-0.91); no effect was observed for non-infectious deaths or after 6 weeks of age. Effects were similar across BCG strains and multivariate models adjusted for socioeconomic status did not affect estimates. CONCLUSION Among BCG-vaccinated newborns, there was a trend for fewer in-hospital deaths from infection associated with maternal BCG priming, especially for males. Providing BCG to adults without a vaccination scar might enhance their offspring's capacity to handle severe infections.

Abstract
Introduction Receiving Bacille Calmette-Guérin (BCG)-Denmark vaccine at birth has been associated with ~40% reductions in all-cause neonatal mortality. We evaluated determinants of BCG skin reaction characteristics by age 2 months and tested the association with subsequent mortality. Methods Prospective observational study amalgamating five trials providing BCG-at-birth that were conducted between 2002 and 2018 in Guinea-Bissau. The reaction status and size were evaluated at home-visits by 2 months of age among 6012 neonates; mortality from 2 to 12 months was assessed at subsequent visits. Reaction determinants were evaluated by binomial regression providing risk ratios (RRs). In Cox-models providing adjusted mortality rate ratios (aMRRs), we assessed the association between (1) having a 2-month reaction (yes/no) and (2) reaction size tertiles and subsequent all-cause mortality risk. A subgroup had their BCG reaction evaluated and were bled at age 4 weeks; their samples underwent in vitro analysis for specific and non-specific cytokine responses. Results The BCG strain was the main determinant for developing a 2-month reaction and the reaction size: the BCG-Russia/BCG-Denmark RR for large-reaction was 0.38 (0.30–0.47) and the BCG-Russia/BCG-Japan RR was 0.61 (0.51–0.72). 5804 infants (96.5%) were reactors by age 2 months; 208 (3.5%) were non-reactors. The 2–12 months mortality risk was 4.8% (10/208) for non-reactors, 2.9% (64/2213) for small reactors, 1.8% (30/1710) for medium reactors and 0.8% (15/1881) for large reactors. The reactor/non-reactor aMRR was 0.49 (0.26–0.95) and there was a linear trend of decreasing mortality with increasing reaction size (p for trend <0.001). BCG reactors had higher 4-week specific and non-specific cytokine responses, responses that were highest among those with large reactions. Conclusion Among BCG-vaccinated infants, having a BCG skin reaction by age 2 months was associated with markedly better survival, as was the reaction size. Our findings thus support that BCG has substantial effects on all-cause mortality. Emphasising at-birth vaccination with immunogenic BCG strains and revaccinating non-reactors and small reactors could have major public health benefits.

Abstract
Introduction Patients with clinical malaria have an increased risk for bacterial bloodstream infections. We hypothesized that asymptomatic malaria parasitemia increases susceptibility for bacterial infections through an effect on the innate immune system. We measured circulating cytokine levels and ex-vivo cytokine production capacity in asymptomatic malaria and compared with controls. Methods Data were collected from asymptomatic participants <5 years old with and without positive malaria microscopy, as well as from hospitalized patients <5 years old with clinical malaria, bacteremia, or malaria/bacteremia co-infections in a malaria endemic region of Burkina Faso. Circulating cytokines (TNF-α, IFN-γ, IL-6, IL-10) were measured using multiplex assays. Whole blood from asymptomatic participants with and without positive malaria microscopy were ex-vivo stimulated with S. aureus, E. coli LPS and Salmonella Typhimurium; cytokine concentrations (TNF-α, IFN-γ, IL-1β, IL-6, IL-10) were measured on supernatants using ELISA. Results Included were children with clinical malaria (n=118), bacteremia (n=22), malaria and bacteremia co-infection (n=9), asymptomatic malaria (n=125), and asymptomatic controls (n=237). Children with either clinical or asymptomatic malaria had higher plasma cytokine concentrations than controls. Cytokine concentrations correlated positively with malaria parasite density with the strongest correlation for IL-10 in both asymptomatic (r=0.63) and clinical malaria (r=0.53). Patients with bacteremia had lower circulating IL-10, TNF-α and IFN-γ and higher IL-6 concentrations, compared to clinical malaria. Ex-vivo whole blood cytokine production to LPS and S. aureus was significantly lower in asymptomatic malaria compared to controls. Whole blood IFN-γ and IL-10 production in response to Salmonella was also lower in asymptomatic malaria. Interpretation In children with asymptomatic malaria, cytokine responses upon ex-vivo bacterial stimulation are downregulated. Further studies are needed to explore if the suggested impaired innate immune response to bacterial pathogens also translates into impaired control of pathogens such as Salmonella spp.

Abstract
Bacillus Calmette-Guérin (BCG) vaccine against tuberculosis (TB) is recommended at birth in TB-endemic areas. Currently, BCG vaccination programmes use "BCG vaccination coverage by 12 months of age" as the performance indicator. Previous studies suggest that BCG-vaccinated children, who develop a scar, have better overall survival compared with BCG-vaccinated children, who do not develop a scar. We summarized the available studies of BCG scarring and child survival. A structured literature search for studies with original data and analysis of BCG scarring and mortality were performed. Combined analyses on the effect of BCG scarring on overall mortality. We identified six studies covering seven cohorts, all from Guinea-Bissau, West Africa, with evaluation of BCG scarring amongst BCG-vaccinated children and follow-up for mortality. Determinants of BCG scarring were BCG strain, intradermal injection route, size of injection wheal, and co-administered vaccines and micronutrients. In a combined analysis, having a BCG scar vs. no BCG scar was associated with a mortality rate ratio (MRR) of 0.61 (95% CI: 0.51-0.74). The proportion with a BCG scar varied from 52 to 93%; the estimated effect of a BCG scar was not associated with the scar prevalence. The effect was strongest in the first (MRR = 0.48 (0.37-0.62)) and second (MRR = 0.63 (0.44-0.92)) year of life, and in children BCG-vaccinated in the neonatal period (MRR = 0.45 (0.36-0.55)). The effect was not explained by protection against TB. Confounding and genetic factors are unlikely to explain the strong association between BCG scarring and subsequent survival. Including "BCG scar prevalence" as a BCG vaccination programme performance indicator should be considered. The effect of revaccinating scar-negative children should be studied.

Abstract
BACKGROUND Pain in the Emergency Department is common and is frequently treated with opioids. Due to the opioid epidemic, it is clinically helpful to decrease opioid usage. The purpose of this study was to evaluate opioid requirement in Emergency Department patients with painful conditions who receive intravenous acetaminophen. METHODS In this prospective cohort study, patients aged 18 years and older and treated with opioids in the acute phase were included. Patients receiving additional intravenous acetaminophen were compared to patients who did not. Primary outcome was opioid requirement, measured in Morphine Equivalent Units (MEU) during Emergency Department stay. Secondary outcomes were opioid requirement after discharge; decrease in pain scores; occurrence of adverse events and patient satisfaction. RESULTS A total of 116 patients were included of whom 76 received intravenous acetaminophen. Opioid consumption in the acute phase was not significantly different (p=0.53) between patients receiving (10.0 MEU (IQR 7.5; 15.0)) and those not receiving acetaminophen: 10.0 MEU (IQR 7.1; 15.0). After discharge these numbers were 15.0 MEU (IQR 7.5; 30.0) versus 30.0 MEU (IQR 15.0; 43.8), respectively (p=0.059). In both groups median NRS pain scores decreased from 9.0 to 4.0 and >80% of patients were satisfied regarding pain treatment. Nine minor adverse events were recorded, equally divided among the groups. CONCLUSIONS The additional use of intravenous acetaminophen did not decrease opioid requirement in adult patients with acute pain during Emergency Department stay. There was a trend towards decreased opioid requirement during 24 h after discharge.

Abstract
OBJECTIVE Self-efficacy expectations are associated with improvements in problematic outcomes widely considered clinically significant (ie, emotional distress, fatigue, and pain), related to positive health behaviors, and as a type of personal agency, inherently valuable. Self-efficacy expectancies, estimates of confidence to execute behaviors, are important in that changes in self-efficacy expectations are positively related to future behaviors that promote health and well-being. The current meta-analysis investigated the impact of psychological interventions on self-efficacy expectations for a variety of health behaviors among cancer patients. METHODS Ovid Medline, PsycINFO, CINAHL, EMBASE, Cochrane Library, and Web of Science were searched with specific search terms for identifying randomized controlled trials (RCTs) that focused on psychologically based interventions. Included studies had (a) an adult cancer sample, (b) a self-efficacy expectation measure of specific behaviors, and (c) an RCT design. Standard screening and reliability procedures were used for selecting and coding studies. Coding included theoretically informed moderator variables. RESULTS Across 79 RCTs, 223 effect sizes, and 8678 participants, the weighted average effect of self-efficacy expectations was estimated as g = 0.274 (P < .001). Consistent with the self-efficacy theory, the average effect for in-person intervention delivery (g = 0.329) was significantly greater than for all other formats (g = 0.154, P = .023; eg, audiovisual, print, telephone, and Web/internet). CONCLUSIONS The results establish the impact of psychological interventions on self-efficacy expectations as comparable in effect size with commonly reported outcomes (distress, fatigue, pain). Additionally, the result that in-person interventions achieved the largest effect is supported by the social learning theory and could inform research related to the development and evaluation of interventions.

Abstract
The main aim of this article is to identify those factors that affect treatment compliance, the extent to which the owners of patients comply with the treatment regimen, and how to improve compliance. The article is mainly based on reports from the medical literature. Although compliance can be measured in several ways, there is no valid and reliable method. For this reason, several methods should be used. Factors that affect treatment compliance in human medicine are (I) the expected effectiveness of treatment, (II) the severity of the disorder, (III) the risks associated with medicine use, (IV) the duration and dosage of medical therapy, (V) patient motivation, and (VI) the doctor-patient relationship. In the literature, in veterinary medicine treatment compliance is reported to range from 44% to 55%, whereas in human medicine it is reported to range from 5% to 96%. Compliance can be improved if (I) the owner can easily incorporate the treatment regimen in his/her daily life, (II) the treatment regimen does not disrupt the owner's daily routine, (III) the owner is informed about and understands the treatment provided, and (IV) the relationship between veterinarian and owner is good. In conclusion, many questions about treatment compliance in veterinary medicine remain unanswered, and research is needed to answer them.
