Background Screening for cytomegalovirus (CMV)-specific antibodies is not routine in some settings. Thus, transfusion of blood products poses risks for susceptible individuals. Objectives To investigate the global pooled CMV seroprevalence among volunteer blood donors. Methods This systematic review and meta-analysis was performed according to PRISMA guidelines. The databases searched included Embase, Google Scholar, Medline, PubMed, Web of Science, and Cochrane Library. Data were extracted independently and analyzed using STATA version 11. Results The global seroprevalence of CMV IgG, CMV IgM, and both CMV IgM and IgG was 83.16% (95% confidence interval [CI]: 78.55–87.77%, I2 = 99.5%), 13.77% (95% CI: 11.59–15.95%, I2 = 98.8%), and 23.78% (95% CI: 10.50–37.06%, I2 = 98.7), respectively. Conclusion The global seroprevalence of CMV was high among blood donors. Therefore, regular CMV screening should be conducted to identify CMV-seronegative blood donors.

Resumen: Se analiza la producción científica sobre videojuegos bélicos. La metodología se sustenta en una revisión sistemática de estudios extraídos de bases de datos (Scopus, Web Of Science y Google Scholar), mediante un meta-análisis, siguiendo criterios de PRISMA-P2015 para identificar los enfoques y metodologías empleadas. Se encontraron 37 estudios entre 2010-2020 en cuatro ámbitos: educativo, psicológico, sociológico o antropológico y tecnológico. Los resultados ofrecen un panorama polarizado, un sector los considera plataformas de propaganda militarista; otro apuesta por utilizarlos como un recurso didáctico, permitiendo la inmersión virtual en acontecimientos históricos; y los técnicos señalan la conveniencia de diseñar videojuegos educativos con el asesoramiento de historiadores para dotarlos de mayor fiabilidad, además de incorporar misiones gamificadas que potencien su jugabilidad. Sin embargo, se precisan estudios que profundicen en la oportunidad que ofrecen estos instrumentos para impulsar el pensamiento crítico y la reflexión frente a la guerra y el sufrimiento de las víctimas.Abstract: Scientific production on war videogames is analyzed. The methodology is based on a systematic review of studies extracted from databases (Scopus, Web of Science and Google Scholar), through a meta-analysis, following the criteria of PRISMA-P2015 to identify the approaches and methodologies used. Thirty-seven studies were found between 2010-2020 in four areas: educational, psychological, sociological or anthropological and technological. The results offer a polarized panorama, one sector considers them militarist propaganda platforms; another is committed to using them as a didactic resource, allowing virtual immersion in historical events; and the technicians point out the convenience of designing educational video games with the advice of historians to make them more reliable, in addition to incorporating gamified missions that enhance their playability. However, studies are needed to delve into the opportunity offered by these instruments to promote critical thinking and reflection in the face of war and the suffering of the victims.

The Relationship

Cognitive functions are essential in any form of exercise. Recently, interest has mounted in addressing the relationship between caffeine intake and cognitive performance during sports practice. This review examines this relationship through a structured search of the databases Medline/PubMed and Web of Science for relevant articles published in English from August 1999 to March 2020. The study followed PRISMA guidelines. Inclusion criteria were defined according to the PICOS model. The identified records reported on randomized cross-over studies in which caffeine intake (as drinks, capsules, energy bars, or gum) was compared to an identical placebo situation. There were no filters on participants’ training level, gender, or age. For the systematic review, 13 studies examining the impacts of caffeine on objective measures of cognitive performance or self-reported cognitive performance were selected. Five of these studies were also subjected to meta-analysis. After pooling data in the meta-analysis, the significant impacts of caffeine only emerged on attention, accuracy, and speed. The results of the 13 studies, nevertheless, suggest that the intake of a low/moderate dose of caffeine before and/or during exercise can improve self-reported energy, mood, and cognitive functions, such as attention; it may also improve simple reaction time, choice reaction time, memory, or fatigue, however, this may depend on the research protocols.

Abstract To date, there is no quantitative review examining the influence of heart rate variability biofeedback (HRV BFB) on the athlete population. Such an undertaking may provide valuable information on the autonomic and respiration responses of athletes when performing HRV BFB. Thus, purpose of this preliminary systematic review and meta-analysis on the effects of HRV BFB on HRV and respiration of athletes. Searches of Springerlink, SportDiscus, Web of Science, PROQUEST Academic Research Library, Google Scholar, and ScienceDirect were conducted for studies that met the following criteria: (1) experimental studies involving athletes that underwent randomized control trial; (2) availability of HRV BFB as a treatment compared with a control (CON)/placebo (PLA); (3) any pre and post HRV variable and/or breathing frequency as dependent variable/s; and, (4) peer-reviewed articles written in English. Four out of 660 studies involving 115 athletes (25 females and 90 males) ages 16–30 years old were assessed in this review. Preliminary findings suggest the promising ability of HRV BFB to improve respiratory mechanics in athlete population. More work is needed to determine the autonomic modulatory effect of HRV BFB in athletes.

ObjectiveTo systematically review and meta-analyse the rate of SARS-CoV-2 genome identification and the presence of SARS-CoV-2 antibodies in breastmilk of mothers with COVID-19.DesignA systematic review of studies published between January 2019 and October 2020 without study design or language restrictions.SettingData sourced from Ovid Embase Classic+Embase, PubMed, Web of Science, Scopus, relevant bibliographies and the John Hopkins University COVID-19 database.PatientsMothers with confirmed COVID-19 and breastmilk tested for SARS-CoV-2 by RT-PCR or for anti-SARS-CoV-2 antibodies.Main outcome measuresPresence of SARS-CoV-2 genome and antibodies in breastmilk.ResultsWe included 50 articles. Twelve out of 183 women from 48 studies were positive for SARS-CoV-2 genome in their breastmilk (pooled proportion 5% (95% CI 2% to 15%; I2=48%)). Six infants (50%) of these 12 mothers tested positive for SARS-CoV-2, with one requiring respiratory support. Sixty-one out of 89 women from 10 studies had anti-SARS-CoV-2 antibody in their breastmilk (pooled proportion 83% (95% CI 32% to 98%; I2=88%)). The predominant antibody detected was IgA.ConclusionsSARS-CoV-2 genome presence in breastmilk is uncommon and is associated with mild symptoms in infants. Anti-SARS-CoV-2 antibodies may be a more common finding. Considering the low proportion of SARS-CoV-2 genome detected in breastmilk and its lower virulence, mothers with COVID-19 should be supported to breastfeed.

Glycemic Profile

This study aimed to perform a systematic review and meta-analysis of the glycemic index (GI) of gluten-free bread (GFB) and its main ingredients. The systematic review followed PRISMA guidelines, using seven electronic databases (PubMed, EMBASE, Scopus, Science Direct, Web of Science, gray literature research with Google Scholar, and patents with Google Patent tool), from inception to November 2020. Eighteen studies met the inclusion criteria evaluating 132 GFB samples. Five articles tested GI in vivo, eleven in vitro; and two studies tested both methods. The analysis showed that 60.7% (95% CI: 40.2–78.1%) of the samples presented high glycemic indexes, evidencing a high glycemic profile for GFB. Only 18.2% (95% CI: 11.7–27.2%) of the bread samples presented in the studies were classified as a low GI. Meta-analysis presented moderate/low heterogenicity between studies (I2 = 61% and <1% for both high and low GIs) and reinforced the proportion of high GIs. Lower GIs were found in formulations based on Colocasia esculenta flour or enriched with fiber, yogurt and curd cheese, sourdough, psyllium, hydrocolloids, enzymes, fructans, and resistant starch, highlighting the efficacy of these ingredients to lower GFBs’ GI. GFB tends to present high GI, impacting the development of chronic diseases when consumed.

Objetivo: Verificar as alterações estruturais e funcionais, evidenciadas através da imagem por ressonância magnética, relacionadas aos déficits de memória identificados em idosos normais, quando comparados a adultos jovens. Metodologia: Procedeu-se à revisão sistemática, cujo protocolo obedeceu ao fluxograma do Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Foram investigadas as bases de dados PubMed, Scopus, EBSCO, utilizando o gerenciador de referências JabRef, na versão 2.10, e o Web of Science, pelo website. Foram incluídos artigos de estudos quase experimentais, transversais, em coorte ou tipo caso-controle, publicados entre 2005 e 2014, em periódicos indexados nacionais e internacionais, cuja amostra incluísse idosos a partir de 60 anos, não dementes, submetidos à investigação de alterações estruturais e funcionais do sistema nervoso central, por ressonância magnética e sua associação com déficits de memória avaliados por testes neuropsicológicos. Resultados: Quanto à técnica de imagem empregada, identificaram-se dois estudos com imagem por ressonância magnética estrutural, seis estudos com utilização de imagem por ressonância magnética funcional, e quatro estudos que empregaram ambas as técnicas. Nos 12 estudos foi identificado o emprego de 38 testes neuropsicológicos distintos, com uma média de cinco testes por estudo, com variação de um a 12 testes. Dentre os testes mais usados, estiveram o WAIS Digit Span Backwards (em sete estudos), o Trail Making Test A and B (em quatro estudos) e o Wechsler Memory Scale (em quatro estudos). Conclusão: Os estudos demonstraram que no envelhecimento normal, ocorre redução do volume de substância branca para-hipocampal, do volume do hipocampo e do córtex entorrinal com redução de memória verbal, possivelmente por desmielinização das fibras; redução das vias que ligam o lobo temporal e frontal, contribuindo para a redução da memória episódica, da memória de trabalho e da fluência verbal; redução da supressão de informações irrelevantes, o que contribui para menor registro de informação; alterações das áreas frontal e parietal que comprometem a memória de reconhecimento; modificações na atividade e na conectividade do default mode network; reorganização das funções cognitivas, bem como alentecimento de resposta por provável redução de ativação do córtex pré- frontal
