Zika virus detection in amniotic fluid and Zika-associated birth defects.

BACKGROUND: Zika virus infection during pregnancy can cause serious birth defects, which include brain and eye abnormalities. The clinical importance of detection of Zika virus RNA in amniotic fluid is unknown. OBJECTIVE: The purpose of this study was to describe patterns of Zika virus RNA testing of amniotic fluid relative to other clinical specimens and to examine the association between Zika virus detection in amniotic fluid and Zika-associated birth defects. Our null hypothesis was that Zika virus detection in amniotic fluid was not associated with Zika-associated birth defects. STUDY DESIGN: We conducted a retrospective cohort analysis of women with amniotic fluid specimens submitted to Colombia's National Institute of Health as part of national Zika virus surveillance from January 2016 to January 2017. Specimens (maternal serum, amniotic fluid, cord blood, umbilical cord tissue, and placental tissue) were tested for the presence of Zika virus RNA with the use of a singleplex or multiplex real-time reverse transcriptase-polymerase chain reaction assay. Birth defect information was abstracted from maternal prenatal and infant birth records and reviewed by expert clinicians. Chi-square and Fisher's exact tests were used to compare the frequency of Zika-associated birth defects (defined as brain abnormalities [with or without microcephaly, but excluding neural tube defects and their associated findings] or eye abnormalities) by frequency of detection of Zika virus RNA in amniotic fluid. RESULTS: Our analysis included 128 women with amniotic fluid specimens. Seventy-five women (58%) had prenatally collected amniotic fluid; 42 women (33%) had amniotic fluid collected at delivery, and 11 women (9%) had missing collection dates. Ninety-one women had both amniotic fluid and other clinical specimens submitted for testing, which allowed for comparison across specimen types. Of those 91 women, 68 had evidence of Zika virus infection based on detection of Zika virus RNA in ≥1 specimen. Testing of amniotic fluid that was collected prenatally or at delivery identified 39 of these Zika virus infections (57%; 15 [22%] infections were identified only in amniotic fluid), and 29 infections (43%) were identified in other specimen types and not amniotic fluid. Among women who were included in the analysis, 89 had pregnancy outcome information available, which allowed for the assessment of the presence of Zika-associated birth defects. Zika-associated birth defects were significantly (P<.05) more common among pregnancies with Zika virus RNA detected in amniotic fluid specimens collected prenatally (19/32 specimens; 59%) than for those with no laboratory evidence of Zika virus infection in any specimen (6/23 specimens; 26%), but the proportion was similar in pregnancies with only Zika virus RNA detected in specimens other than amniotic fluid (10/23 specimens; 43%). Although Zika-associated birth defects were more common among women with any Zika virus RNA detected in amniotic fluid specimens (ie, collected prenatally or at delivery; 21/43 specimens; 49%) than those with no laboratory evidence of Zika virus infection (6/23 specimens; 26%), this comparison did not reach statistical significance (P=.07). CONCLUSION: Testing of amniotic fluid provided additional evidence for maternal diagnosis of Zika virus infection. Zika-associated birth defects were more common among women with Zika virus RNA that was detected in prenatal amniotic fluid specimens than women with no laboratory evidence of Zika virus infection, but similar to women with Zika virus RNA detected in other, nonamniotic fluid specimen types.

Fetal demise and SARS-CoV-2 infection during pregnancy: Histopathological and immunohistochemical findings of three cases referred to the Colombian National Institute of Health.

BACKGROUND: Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection during pregnancy is related with adverse maternal, fetal, and neonatal outcomes. Placental SARS-CoV-2 involvement may include various degrees of inflammation and malperfusion leading to diverse pregnancy complications. METHODS: Placental, fetal and umbilical cord samples of three fetal demise cases that occurred in the context of maternal SARS-CoV-2 infections were analyzed. Cases were notified to the Colombian SARS-CoV-2 National Surveillance System. RT-PCR and immunohistochemistry (IHC) analysis were employed to identify potential tissue viral involvement. RESULTS: RT-PCR and IHC confirmed the presence of viral genomes and antigens in placental and umbilical cord tissues. Histopathological analysis revealed findings consistent with placental malperfusion and inflammation. CONCLUSIONS: SARS-CoV-2 infection during pregnancy can lead to placental dysfunction and damage compromising fetal survival. Many questions regarding SARS-CoV-2 dynamics during pregnancy including placental physiopathology and in utero transmission are still pending definitive answers.

SARS-CoV-2 infection in newborn infants: descriptive epidemiological analysis of cases reported to the Colombian national surveillance system during the first pandemic year, March 2020-February 2021.

OBJECTIVE: To describe the clinical and epidemiological characteristics of newborn infants with SARS-CoV-2 infection notified in the Colombian Public Health Surveillance System. DESIGN: This epidemiological descriptive analysis was conducted using the data of all cases of newborn infants with confirmed SARS-CoV-2 infection notified in the surveillance system. Absolute frequencies and central tendency measures were calculated and a bivariate analysis comparing variables of interest with symptomatic and asymptomatic disease was performed. SETTING: Population-based descriptive analysis. PATIENTS: Laboratory-confirmed COVID-19 cases in newborn infants (aged ≤28 days of life) reported to the surveillance system from 1 March 2020 to 28 February 2021. RESULTS: 879 newborns were identified, corresponding to 0.04% of all reported cases in the country. The mean age at diagnosis was 13 days (range 0-28 days), 55.1% were male and most (57.6%) were classified as symptomatic. Preterm birth and low birth weight were identified in 24.0% and 24.4% of the cases, respectively. Common symptoms were fever (58.3%), cough (48.3%) and respiratory distress (34.9%). A higher prevalence of symptomatic newborns was seen in individuals with low birth weight for gestational age (prevalence ratio (PR): 1.51, 95% CI: 1.44 to 1.59) and newborns with underlying conditions (PR: 1.33, 95% CI: 1.13 to 1.55). CONCLUSIONS: There were a low proportion of confirmed COVID-19 cases in the newborn population. A substantial number of newborns were classified as symptomatic, having low birth weight and being preterm. Clinicians caring for COVID-19-infected newborns should be aware of population characteristics that potentially contribute to disease manifestations and severity.

A strong relationality view of mindfulness and flourishing I-Thou relations: A dyadic analysis.

Despite the increasing popularity of mindfulness and research concerning its role in relationships, there is limited strongly relational theoretical discussion explaining the role of mindfulness in intimate couple relationships. In this article, we articulate a strongly relational view of the role of mindfulness in couple relationships. We then empirically test theoretically relevant associations using dyadic data (N = 514 heterosexual couples) from couples in the U.S. and Canada. In Study 1, we evaluated a model with male and female mindfulness predicting couple relational-connectivity (a sense of friendship, intimacy, and belonging) through couple responsible actions (behaviors intentionally enacted to strengthen couple connection), which indicated a fully mediated effect; the influence of male and female mindfulness on couple relational-connectivity was fully accounted for by associations with couple responsible actions (indirect standardized betas of .08). With a subsample of 120 of these couples, in Study 2 we used a daily diary design to explore how mindfulness was associated with ethical responsiveness (a tendency to respond benevolently to a perceived need), responsible actions, and relational-connectivity at the within-person level. Study 1 results were reinforced, showing stronger associations in these within-person analyses (indirect standardized betas of .21 and .23). In conceptualizing individual mindfulness and ethical responsiveness as dimensions of a more relational form of mindfulness, one way by which mindfulness may influence couples' relational-connectivity is through its influence on responsible actions. These results provide initial support for using a strongly relational paradigm to understand the role of mindfulness in intimate couple relationships.

Pregnancy, Birth, Infant, and Early Childhood Neurodevelopmental Outcomes among a Cohort of Women with Symptoms of Zika Virus Disease during Pregnancy in Three Surveillance Sites, Project Vigilancia de Embarazadas con Zika (VEZ), Colombia, 2016-2018.

Project Vigilancia de Embarazadas con Zika (VEZ), an intensified surveillance of pregnant women with symptoms of the Zika virus disease (ZVD) in Colombia, aimed to evaluate the relationship between symptoms of ZVD during pregnancy and adverse pregnancy, birth, and infant outcomes and early childhood neurodevelopmental outcomes. During May-November 2016, pregnant women in three Colombian cities who were reported with symptoms of ZVD to the national surveillance system, or with symptoms of ZVD visiting participating clinics, were enrolled in Project VEZ. Data from maternal and pediatric (up to two years of age) medical records were abstracted. Available maternal specimens were tested for the presence of the Zika virus ribonucleic acid and/or anti-Zika virus immunoglobulin antibodies. Of 1213 enrolled pregnant women with symptoms of ZVD, 1180 had a known pregnancy outcome. Results of the Zika virus laboratory testing were available for 569 (48.2%) pregnancies with a known pregnancy outcome though testing timing varied and was often distal to the timing of symptoms; 254 (21.5% of the whole cohort; 44.6% of those with testing results) were confirmed or presumptive positive for the Zika virus infection. Of pregnancies with a known outcome, 50 (4.2%) fetuses/infants had Zika-associated brain or eye defects, which included microcephaly at birth. Early childhood adverse neurodevelopmental outcomes were more common among those with Zika-associated birth defects than among those without and more common among those with laboratory evidence of a Zika virus infection compared with the full cohort. The proportion of fetuses/infants with any Zika-associated brain or eye defect was consistent with the proportion seen in other studies. Enhancements to Colombia's existing national surveillance enabled the assessment of adverse outcomes associated with ZVD in pregnancy.

Occupational exposure to blood borne pathogens among healthcare workers: a cross-sectional study of a registry in Colombia.

BACKGROUND: Occupational exposure to blood borne pathogens caused by percutaneous injuries or mucosal contamination is frequent among Healthcare Workers (HCW). METHODS: A cross-sectional analysis of HCW with an occupational exposure to blood reported to professional risk insurance agencies between 2009 and 2014 was performed. Comparisons between groups according to exposure level (mild, moderate, and severe) were evaluated. RESULTS: Two thousand, four hundred three reports were classified according exposure as mild 2.7 %, moderate 74.8 %, severe 21.9 %. Factors related: health sciences student with mild exposure events [adjusted odds ratio (AOR) 11.91, 95 % CI 5.13-27.61, p < 0.00001], and physician with moderate exposure events (AOR 1.90, 95 % CI 1.17-3.07, p = 0.009). Factors inversely related: physician with severe exposure events (AOR 0.54, 95 % CI 0.32-0.91, p = 0.02) and health sciences student with moderate exposure events (AOR 0.08, 95 % CI 0.04-0.15, p < 0.00001). It was found an important relationship between severe events with infectious diseases specialist assessment, and follow-up adherence. Additionally, a case of Human Immunodeficiency Virus seroconversion was presented (0.0004 %), no other seroconversions were observed. CONCLUSIONS: Occupational exposure events must be managed according to established protocols, but adherence failure was evident with the exception of severe exposure cases. Thus, interventions to enhance occupational safety are required. Occupation must be considered as a risk factor during initial assessment of events.
