Single-cell sequence can therefore better reflect the pathogenesis of asthma, as it can clarify the function and regulatory mechanism of DNA methylation in asthma, and detect new genes and molecular markers that may become therapeutic targets in this disease.BACKGROUND This is a case report of an immunocompromised patient with a history of non-Hodgkin lymphoma and persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection who was seronegative and successfully treated with convalescent plasma. CASE REPORT A 63-year-old woman with a past medical history of non-Hodgkin lymphoma in remission while on maintenance therapy with the anti-CD20 monoclonal antibody, obinutuzumab, tested positive for SARS-CoV-2 via nasopharyngeal reverse transcription polymerase chain reaction (RT-PCR) testing over 12 weeks and persistently tested seronegative for immunoglobulin G (IgG) antibodies using SARS-CoV-2 IgG chemiluminescent microparticle immunoassay technology. During this time, the patient experienced waxing and waning of symptoms, which included fever, myalgia, and non-productive cough, but never acquired severe respiratory distress. She was admitted to our hospital on illness day 88, and her symptoms resolved after the administration of convalescent plasma. CONCLUSIONS As the understanding of the pathogenesis of SARS-CoV-2 continues to evolve, we can currently only speculate about the occurrence of chronic infection vs. reinfection. The protective role of antibodies and their longevity against SARS-CoV-2 remain unclear. Since humoral immunity has an integral role in SARS-CoV-2 infection, various phase 3 vaccine trials are underway. In the context of this pandemic, the present case demonstrates the challenges in our understanding of testing and treating immunocompromised patients.
To evaluate the ability to predict central venous pressure by ultrasound measured inferior vena cava and aortic diameters in a PICU population and to assess interoperator concordance.

Noninterventional observational study.

PICU of a tertiary-care academic center.

Eighty-eight pediatric patients (0-16 yr old) with a central venous catheter in place were studied. RU320521 Sixty-nine percent of the patients received positive-pressure ventilation.

None.

An experienced and a nonexperienced operator used ultrasound to measure the maximal diameter of inferior vena cava and minimal diameter of the inferior vena cava and the maximum diameter of the abdominal aorta from the subxiphoid window. The inferior vena cava collapsibility index and the ratio of maximal diameter of inferior vena cava/maximum diameter of the abdominal aorta were then derived. The central venous pressure was measured using a central venous catheter and recorded. Twenty-three patients had low central venous pressure values (≤ 4 mm Hg), 35 patienrior vena cava collapsibility index or ratio of maximal diameter of inferior vena cava/maximum diameter of the abdominal aorta thresholds appear to be able to differentiate children with high or low central venous pressure. However, the actual clinical application of these statistically significant results remains limited, especially by the intrinsic flaws of the procedure.
To determine whether shock index, coronary perfusion pressure, or rate pressure product in the first 24 hours after congenital heart surgery are independent predictors of subsequent clinically significant adverse outcomes.

A retrospective cohort study.

A tertiary care center.

All patients less than 18 years old who underwent cardiac surgery at Boston Children's Hospital between January 1, 2010, and December 31, 2018.

None.

Shock index (heart rate/systolic blood pressure), coronary perfusion pressure (diastolic blood pressure-right atrial pressure), and rate pressure product (heart rate × systolic blood pressure) were calculated every 5 seconds, and the median value for the first 24 hours of cardiac ICU admission for each was used as a predictor. The composite, primary outcome was the occurrence of any of the following adverse events in the first 7 days following cardiac ICU admission cardiopulmonary resuscitation, extracorporeal cardiopulmonary resuscitation, mechanical circulatory support, unplanimary hemodynamic variables.
Both shock index and coronary perfusion pressure may offer predictive value for adverse outcomes following cardiac surgery in children, although they are not superior to the primary hemodynamic variables.
To evaluate the association of preoperative risk factors and postoperative outcomes in infants with complex congenital heart disease.

Single-center retrospective cohort study.

Neonatal ICU and cardiovascular ICU.

Infants of all gestational ages, born at Texas Children's Hospital between 2010 and 2016, with complex congenital heart disease requiring intervention prior to discharge.

None.

A total of 399 patients were enrolled in the study. Preoperative risk factors included feeding, type of feeding, feeding route, and cardiac lesion. Postoperative outcomes included necrotizing enterocolitis, hospital length of stay, and days to full feeds. The occurrence rate of postoperative necrotizing enterocolitis (all stages) was 8%. Preoperative feeding, type of feeding, feeding route, and cardiac lesion were not associated with higher odds of postoperative necrotizing enterocolitis. Cardiac lesions with ductal-dependent systemic blood flow were associated with a hospital length of stay of 19.6 days longer thament strategies in caring for these infants, as they may incur more hospital costs and resources without significant medical benefit.
Although cardiac lesions with ductal-dependent systemic blood flow are considered high risk and may increase length of stay and days to achieve full feeds, they are not associated with a higher risk of postoperative necrotizing enterocolitis. Nasogastric route is not associated with a significantly higher risk of necrotizing enterocolitis, but longer length of stay and days to reach full feeds. These findings challenge our perioperative management strategies in caring for these infants, as they may incur more hospital costs and resources without significant medical benefit.
