SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal
Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by
the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration
with more than 50 laboratories distributed nationwide.
Methods By applying recent phylodynamic models that allow integration of individual-based
travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal.
Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from
European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland),
which were consistent with the countries with the highest connectivity with Portugal.
Although most introductions were estimated to have occurred during early March 2020, it is
likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the
first cases were confirmed.
Conclusions Here we conclude that the earlier implementation of measures could have
minimized the number of introductions and subsequent virus expansion in Portugal. This
study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and

CondutĂąncia da pele como indicador de dor aguda no recĂ©m-nascido : estudo comparativo com frequĂȘncia cardĂaca, saturação de oxigĂȘnio e escalas comportamentais de dor
Tese (doutorado)âUniversidade de BrasĂlia, Programa de PĂłs-Graduação em CiĂȘncias MĂ©dicas, 2011.Objetivos: Comparar os escores da atividade de condutĂąncia da pele (ACP), da frequĂȘncia cardĂaca (FC) mĂĄxima, da saturação de oxigĂȘnio (SATO2) mĂnima, e das escalas comportamentais de dor Neonatal Facial Coding System (NFCS), Neonatal Infant Pain Scale (NIPS) e COMFORT modificada frente a um estĂmulo doloroso agudo, e se eles preenchem os parĂąmetros psicofĂsicos de um marcador de dor (intensidade, reatividade, direção, regulação e inclinação). MĂ©todo: Estudo longitudinal prospectivo com 41 recĂ©m-nascidos de termo saudĂĄveis. As medidas
estudadas foram: FC mĂĄxima e SATO2 mĂnima; variĂĄveis da ACP: nĂșmero de ondas por segundo (NOps) e ĂĄrea sob a curva das ondas (ASC); escores das escalas comportamentais de dor acima citadas. Os escores foram obtidos em perĂodos rotulados como antes, durante e apĂłs uma punção do calcanhar. Resultados: A intensidade entre os perĂodos foi significante para o NOps (p<0,01), ASC (p<0,05), FC mĂĄxima (p<0,01), SATO2 mĂnima (p<0,01), NFCS (p<0,01), NIPS (p<0,01) e
COMFORT modificada (p0,05). O parùmetro regulação foi significante para as variåveis NOps (p<0,01), ASC (p<0.05), FC måxima (p<0,01),
SATO2 mĂnima (p<0,01) e para todas as escalas comportamentais de dor (p<0,01).
A inclinação foi significativamente estatĂstica para a SATO2 mĂnima e as escalas
comportamentais de dor NIPS e COMFORT modificada (p<0,05). NĂŁo foi encontrada
correlação entre os nĂveis de ACP e os escores das demais variĂĄveis estudadas.
ConclusĂ”es: As respostas da ACP, da FC mĂĄxima, da SATO2 mĂnima e das escalas
comportamentais de dor NFCS, NIPS e COMFORT modificada sĂŁo similares em eventos dolorosos em recĂ©m-nascidos. Todas as variĂĄveis estudadas preenchem os parĂąmetros psicofĂsicos de um marcador de dor e servem como medidas vĂĄlidas para o seu diagnĂłstico, devendo ser usadas de acordo com as necessidades do contexto. ______________________________________________________________________________ ABSTRACTObjectives: To compare the scores of the skin conductance activity (SCA), maximum heart rate (HR), minimum oxygen saturation (OS), and Neonatal Facial Coding System (NFCS), Neonatal Infant Pain Scale (NIPS) and modified COMFORT behavioral pain scales front to painful stimulus, and if they fit the psychophysical parameters to a pain marker (intensity, reactivity, direction, regulation and slope). Method: Observational prospective study including 41 healthy full term newborns. The measurements studied were: the maximum HR and the minimum OS; the SCA variables: number of waves per second (NWps) and relative area under the curve of
waves (AUC); the scores of behavioral pain scales cited above. The measurements
were performed in periods labeled before, during, and after a heel prick. Results:
The values measured for intensity between periods was significant for the NWps
(p0.05). The regulation parameter was significant for the variables NWps (p<0.01), AUC (p<0.05), maximum HR (p<0.01), minimum OS (p<0.01), and to all behavioral pain scales (p<0.01). The slope was statistically significant for the minimum OS, and to NIPS and modified COMFORT scales (p<0.05). There was not significantly correlation among the SCA scores and the scores of all others variables. Conclusions: It was concluded that the responses of the SCA, maximum HR, minimum OS, and NFCS,
NIPS and modified COMFORT behavioral pain scales are similarly in painful events,
that they fit the psychophysical parameters of a pain marker and serve as valuable
measures for pain diagnostic working the use in accordance with the needs of the context
Sleep deprivation, pain and prematurity: a review study
The aim was to describe current reports in the scientific literature on sleep in the intensive care environment and sleep deprivation associated with painful experiences in premature infant. A systematic search was conducted for studies on sleep, pain, premature birth and care of the newborn. Web of Knowledge, MEDLINE, LILACS, Cochrane Library, PubMed, EMBASE, Scopus, VHL and SciELO databases were consulted. The association between sleep deprivation and pain generates effects that are observed in the brain and the behavioral and physiological activity of preterm infants. Polysomnography in intensive care units and pain management in neonates allow comparison with the first year of life and term infants. We have found few references and evidence that neonatal care programs can influence sleep development and reduce the negative impact of the environment. This evidence is discussed from the perspective of how hospital intervention can improve the development of premature infants
Pregnancy outcomes and child development effects of SARS-CoV-2 Infection (PROUDEST Trial) : protocol for a multicenter, prospective cohort study
Background: A growing body of evidence suggests that SARS-COV-2 infection during pregnancy may affect maternal-fetal outcomes and possibly result in implications for the long-term development of SARSCoV-2âexposed children. Objective: The PROUDEST (Pregnancy Outcomes and Child Development Effects of SARS-CoV-2 Infection Study) is a multicenter, prospective cohort study designed to elucidate the repercussions of COVID19 for the global health of mothers and their children. Methods: The PROUDEST trial comprises 2 prospective, sequential substudies. The PREGNANT substudy will clinically assess the effects of SARS-CoV-2 infection on pregnancy, childbirth, and puerperium from a mechanistic standpoint to elucidate the pregnancy-related inflammatory and immunological phenomena underlying COVID-19. Pregnant women aged 18-40 years who have been exposed (proven with laboratory tests) to SARS-CoV-2 (group A; n=300) will be compared to control subjects with no laboratory evidence of in-pregnancy exposure to the virus (group B; n=300). Subjects exposed to other infections during pregnancy will be excluded. The BORN substudy is a long-term follow-up study that will assess the offspring of women who enrolled in the prior substudy. It will describe the effects of SARS-CoV-2 exposure during pregnancy on childrenâs growth, neurodevelopment, and metabolism from birth up to 5 years of age. It includes two comparison groups; group A (exposed; n=300) comprises children born from SARS-CoV-2â exposed pregnancies, and group B (controls; n=300) comprises children born from nonexposed mothers. Results: Recruitment began in July 2020, and as of January 2021, 260 pregnant women who were infected with SARS-CoV-2 during pregnancy and 160 newborns have been included in the study. Data analysis is scheduled to start after all data are collected. Conclusions: Upon completion of the study, we expect to have comprehensive data that will provide a better understanding of the effects of SARS-CoV-2 infection and related inflammatory and immunological processes on pregnancy, puerperium, and infancy. Our findings will inform clinical decisions regarding the care of SARS-CoV-2âexposed mothers and children and support the development of evidence-based public health policies.Faculdade de Medicina (FMD)Faculdade UnB CeilĂąndia (FCE
Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries
Background
Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks.
Methods
The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned.
Results
A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31).
Conclusion
Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
