participants) and 12 months' follow-up (33.7% fibrin sealant group versus 14.5% control group; 29 participants versus 12 participants). The studies did not report postoperative pancreatic fistula, quality of life, or cost effectiveness. AUTHORS' CONCLUSIONS Based on the current available evidence, fibrin sealants may have little or no effect on postoperative pancreatic fistula in people undergoing distal pancreatectomy. The effects of fibrin sealants on the prevention of postoperative pancreatic fistula are uncertain in people undergoing pancreaticoduodenectomy. Copyright © 2020 The Cochrane Collaboration.

Although specific mechanisms of risk remain largely unknown, theorists and researchers highlight the importance of the parent-child relationship. The current study focused on one aspect of this relationship the dynamic exchange of facial affect during interactions. Specifically, we examined the relation between children's history of suicidal ideation (SI) and synchrony of facial expressions during positive and negative mother-child interactions. METHODS Participants were 353 mother-child dyads. Of these, 44 dyads included a child with an SI history. Dyads engaged in positive and negative discussions during which their facial electromyography was recorded from mothers and children to index second-to-second changes in positive (zygomaticus) and negative (corrugator) facial affect. RESULTS Child SI dyads were characterized specifically by reduced synchrony of positive facial affect during the positive discussion compared to dyads without child SI. CONCLUSIONS These findings suggest child SI dyads exhibit reduced synchrony of normative positive expressions during mother-child interactions. If replicated and extended in longitudinal research, these results may help to explain one mechanism of risk among children with SI. © 2020 Association for Child and Adolescent Mental Health.BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) frequently co-occurs with other psychiatric disorders. Twin studies have established that these co-occurrences are in part due to shared genetic risks. However, the strength of these genetic overlaps and the potential heterogeneity accounted for by type of psychiatric symptoms, age, and methods of assessment remain unclear. We conducted a systematic review to fill this gap. METHODS We searched PubMed, PsycINFO, Embase, and Web of Science until March 07, 2019. Genetic correlations (rg ) were used as effect size measures. RESULTS A total of 31 independent studies fulfilled the inclusion criteria. The pooled estimates showed that the associations between ADHD and other psychiatric symptoms were partly explained by shared genetic factors, with a pooled genetic correlation of 0.50, 95% confidence interval 0.46-0.60. The genetic correlations (rg ) between ADHD and externalizing (rg  = .49 [0.37-0.61]), internalizing (rg  = .50 [0.39-0.69]), and neurodevelopmental (rg  = .56 [0.47-0.66]) symptoms were similar in magnitude. The genetic correlations in childhood and adulthood were rg  = .53 (0.43-0.63) and rg  = .51 (0.44-0.56), respectively. For methods of assessment, the genetic correlations were also similar in strength, self-reports rg  = .52 (0.47-0.58), other informants rg  = .55 (0.41-0.69), and combined raters rg  = .50 (0.33-0.65). CONCLUSIONS These findings indicate that the co-occurrence of externalizing, internalizing, and neurodevelopmental disorder symptoms in individuals with ADHD symptoms in part is due to a shared genetic risk.

Thus, it is essential to find out technologies to guarantee this product for a longer time. Flowers of four species (borage [Borago officinalis], heartsease [Viola tricolor], kalanchoe [Kalanchoe blossfeldiana], and dandelion [Taraxacum officinale]) were subjected to freezing (in their natural form and in ice cubes) and analyzed in terms of visual appearance, the content of flavonoids, hydrolysable tannins, phenolics, antioxidant activity (2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and reducing power), and microbial quality after storage for 1 and 3 months. Flowers in ice cubes showed similar appearance to fresh ones during the 3 months of storage, whereas frozen flowers were only equivalent up to 1 month with the exception of kalanchoe. Even though flowers in ice cubes showed good appearance after 3 months of storage, they had the lowest values of bioactive compounds and antioxidant activity. On the conthat each flower has different behavior at frozen and ice cubes storage. However, freezing flowers maintain/increase the contents of bioactive compounds, while ice cubes not. Both treatments are effective in protecting flowers from microorganism growth. So, suggesting that both freezing treatments can be used as a preservative method and may allow keeping the flowers after their flowering times. © 2020 Institute of Food Technologists®.BACKGROUND Preschool ADHD symptoms have predictive utility for later presence of ADHD diagnoses (Harvey, Youngwirth, Thakar, & Errazuriz, 2009, Journal of Consulting and Clinical Psychology, 77, 349; Lahey et al., 2004, American Journal of Psychiatry, 161(11), 2014), yet some level of inattention, hyperactivity, and impulsivity are present even in typically developing preschoolers. Physical activity (PA) is known to have a broad spectrum of positive effects on the brain in school-age typically developing children (Centers for Disease Control and Prevention, 2010, The association between school based physical activity, including physical education, and academic performance. Atlanta, GA U.S. Department of Health and Human Services), including functions impaired by ADHD (Halperin, Berwid, & O'Neill, 2014, Child and Adolescent Psychiatric Clinics of North America, 23, 899), yet links between PA and ADHD levels and impairments have rarely been studied in either typically developing or at-risk preschool children. Importantly, impaired processing speed (PS), though not a symptom of ADHD, is a robust neuropsychological correlate (Willcutt & Bidwell, 2011, Treating attention deficit hyperactivity disorder Assessment and intervention in developmental context.
