Common Clinical Scenarios of Systemic Hypertension in the NICU.

Hypertension affects ∼1% to 3% of newborns in the NICU. However, the identification and management of hypertension can be challenging because of the lack of data-driven diagnostic criteria and management guidelines. In this review, we summarize the most recent approaches to diagnosis, evaluation, and treatment of hypertension in neonates and infants. We also identify common clinical conditions in neonates in whom hypertension occurs, such as renal vascular and parenchymal disease, bronchopulmonary dysplasia, and cardiac conditions, and address specific considerations for the evaluation and treatment of hypertension in those conditions. Finally, we discuss the importance of ongoing monitoring and long-term follow-up of infants diagnosed with hypertension.

Predictors of venous thromboembolism among infants in children's hospitals in the United States: a retrospective Pediatric Health Information Study.

OBJECTIVES: Examine: (1) Prevalence of diagnosed venous thromboembolism (VTE) in infants <6 months discharged from U.S. NICUs; (2) Associations between sociodemographic and clinical factors and VTE; (3) Secondary outcomes related to VTE. STUDY DESIGN: Multivariable logistic regressions examined associations between VTE and sociodemographic and clinical factors among infants <6 months discharged from Pediatric Health Information System (PHIS) NICUs between 2016 and 2019. RESULTS: Of 201,033 infants, 2720 (1.35%) had diagnosed VTE. Birthweight 300-1000 g (aOR 3.14, 95% CI 2.54-3.88), 1000-1500 g (aOR 1.77, 95% CI 1.40-2.42) versus 2500-3999 g, and public (aOR 1.18, 95% CI 1.02-1.37) versus private insurance were associated with increased odds of VTE, as were CVC, TPN, mechanical ventilation, infection, ECMO, and surgery. All types of central lines (non-tunneled and tunneled CVCs, PICCs, and umbilical catheters) had higher odds of VTE than not having that type of line. CVCs in upper versus lower extremities had higher odds of VTE. CONCLUSION: Infants with risk factors may require monitoring for VTE. Results may inform VTE prevention.

Maternal-to-Fetal Transmission of Syphilis and Congenital Syphilis.

Between 2012 and 2018, rates of congenital syphilis increased by 291% in the United States. In 2018, the rate of congenital syphilis was the highest it has been since 1995. Given these concerning epidemiologic trends, this review seeks to summarize the maternal-to-fetal transmission of syphilis to ensure adequate care of affected mothers and their infants. It also serves as a call to reinvest public health resources and reestablish infrastructure to ensure reversal of this concerning trend to stop preventable perinatal deaths, associated morbidities, and long-term consequences of congenital syphilis.

Will prenatal exposure to SARS-CoV-2 define a birth cohort with accelerated aging in the century ahead?

The 1918 Influenza pandemic had long-term impacts on the cohort exposed in utero which experienced earlier adult mortality, and more diabetes, ischemic heart disease, and depression after age 50. It is possible that the Coronavirus Disease 2019 (COVID-19) pandemic will also have long-term impacts on the cohort that was in utero during the pandemic, from exposure to maternal infection and/or the stress of the pandemic environment. We discuss how COVID-19 disease during pregnancy may affect fetal and postnatal development with adverse impacts on health and aging. Severe maternal infections are associated with an exaggerated inflammatory response, thromboembolic events, and placental vascular malperfusion. We also discuss how in utero exposure to the stress of the pandemic, without maternal infection, may impact health and aging. Several recently initiated birth cohort studies are tracking neonatal health following in utero severe acute respiratory syndrome virus 2 (SARS-CoV-2) exposure. We suggest these cohort studies develop plans for longer-term observations of physical, behavioral, and cognitive functions that are markers for accelerated aging, as well as methods to disentangle the effects of maternal infection from stresses of the pandemic environment. In utero exposure to COVID-19 disease could cause developmental difficulties and accelerated aging in the century ahead. This brief review summarizes elements of the developmental origins of health, disease, and ageing and discusses how the COVID-19 pandemic might exacerbate such effects. We conclude with a call for research on the long-term consequences of in utero exposure to maternal infection with COVID-19 and stresses of the pandemic environment.

A practical index to predict 30-day mortality after major amputation.

BACKGROUND: Patients at risk of mortality after amputation have not been well identified. We sought to devise a clinical index predicting 30-day mortality after amputation that would allow stratification of intensity of postoperative care. METHODS: The National Surgical Quality Improvement Program (NSQIP) database (2005-2009) was analyzed for patients who had above- or below-knee amputations. An additive risk index was created based on logistic regression that examined patient demographics, comorbidities, and operative characteristics. A threshold score for clinical action was identified as the score at which the gain in certainty was maximized. The primary outcome measure was 30-day mortality. RESULTS: Among 9244 patients analyzed, there were 744 deaths (8.1%) at 30 days, with 280 occurring after hospital discharge (37.9%). The final index includes 11 components with a total score range of 0-13: age (60-79 or ≥80 years), history of congestive heart failure, chronic obstructive pulmonary disease, or major cardiac surgery, using steroid medications, having dependent functional status, dyspnea, being on dialysis, having impaired sensorium, or preoperative sepsis. This index has a c-statistic of 0.7391, and the score at which clinical action should be taken is ≥5. The observed probability of 30-day mortality increased from 1.06% at a score of 1 to 10% at 5 and 38.5% at a score of 10. CONCLUSIONS: More than one-third of deaths within 30 days of major amputation occur after discharge from acute care. A novel index to predict 30-day mortality after major amputation is described. Patients receiving a score ≥5 face a substantial risk of mortality and should be held in the hospital longer or, if discharged, receive closer postoperative follow-up.
