Impact of the Fetal Echocardiogram on Maternal Depression and Well-Being.

Fetal echocardiography allows for prenatal diagnosis of congenital heart disease (CHD). The objective of this study is to assess for the impact of fetal echocardiogram on levels of well-being and depression in pregnant women. Adult pregnant women carrying a fetus < 31-week gestational age were enrolled in the prospective observational study from February 2022 to June 2022. These subjects were split into two cohorts: those with CHD and those without CHD. Surveys were distributed prior to the fetal echocardiogram, six weeks later and six weeks after delivery. These surveys consisted of the Edinburgh Postpartum Depression Scale (EPDS) and questions about topics, such as anxiety and social support. Of the 152 subjects enrolled, 14 women had a fetus with CHD and 138 women had a fetus without CHD. Initial EPDS scores were elevated for the study population compared to the general population. Six weeks later, EPDS scores remained elevated. For the post-partum surveys, the EPDS scores were decreased below the rate of the general population for the group without CHD and similar to the general population rate for the CHD group. Anxiety, worry, and guilt remained low for both groups after the initial survey. Counseling from the pediatric cardiologist may help decrease anxiety and worry. Social support, like support groups, may be helpful for women carrying a fetus with CHD.

Ventricular Arrhythmia and COVID-19 Vaccine-associated Myocarditis.

17-year-old male presented with COVID-19 vaccine-associated myocarditis. Six months later, due to chest discomfort with exercise, the patient underwent an exercise stress test that revealed a 3-beat run of nonsustained ventricular tachycardia at 230 bpm at peak exercise. The long-term outcomes of COVID-19 vaccine-associated myocarditis are unclear. This patient had nonsustained ventricular tachycardia over 6 months after diagnosis.

Haemodynamic and clinical variables after surgical systemic to pulmonary artery shunt placement versus arterial ductal stenting.

BACKGROUND: Transcatheter stenting of the arterial duct is an alternative to surgical systemic to pulmonary artery shunt in neonates with parallel circulation. The current study compares haemodynamic and laboratory values in these patients for the first 48 hours after either intervention. METHODS: Neonates with ductal dependent pulmonary blood flow who underwent surgical shunt placement or catheter-based arterial ductal stent placement between January 2013 and January 2022 were identified. Haemodynamic variables included heart rate, blood pressure, near infrared spectroscopy, central venous pressure, vasoactive inotropic score, and arterial saturation. Laboratory variables collected included blood urea nitrogen, serum creatinine, and serum lactate. Variables were collected at baseline, upon post-procedural admission, 6 hours after admission, 12 hours after admission, and 48 hours after admission. Secondary outcomes included post-procedural mechanical ventilation duration, post-procedural hospital length of stay, need for reintervention, need for extracorporeal membrane oxygenation, cardiac arrest, and inpatient mortality. RESULTS: Of the 52 patients included, 38 (73%) underwent shunt placement while 14 (27%) underwent a stent placement. Heart rates, renal oxygen extraction ratio, and cerebral oxygen extraction ratio were significantly lower in the stent group (p = <0.01, 0.01, and < 0.01, respectively).Haemoglobin and vasoactive inotropic scores were significantly lower in the stent group (p = <0.01, <0.01, respectively). The stent group had increased risk for cardiac arrest (p = 0.04). CONCLUSION: Patients who undergo arterial ductal stent placement have lower heart rates, haemoglobin, renal oxygen extraction ratio, cerebral oxygen extraction ratio, and vasoactive inotropic score in the first 48 hours post-procedure compared to patients with shunt placement.

Appropriate use of echocardiography for palpitations in paediatric cardiology clinics.

OBJECTIVES: Identify diagnostic yield and frequency of echocardiograms for palpitation-related indications at outpatient paediatric cardiology clinics in relation to the 2014 ACC/AAP/AHA/ASE/HRS/SCAI/SCCT/SCMR/SOPE appropriate use criteria for Initial Transthoracic Echocardiography in Outpatient Paediatric Cardiology. STUDY DESIGN: A single-centre, retrospective study of children presenting for evaluation of a chief complaint of palpitations to outpatient paediatric cardiology clinics from 2015 to 2017. Palpitations were defined as an unpleasant sensation of rapid, irregular, and/or forceful beating of the heart. Indications for echocardiogram in patients were retrospectively classified based on the appropriate use criteria as "appropriate," "may be appropriate," or "rarely appropriate." The incidence of abnormal and incidental echocardiographic findings for each category was determined. RESULTS: A total of 286 patients presented with palpitations, with 128 (52% female) meeting inclusion criteria. Exclusion criteria included patients with additional cardiac complaints, prior echocardiogram, or history of congenital heart disease. Echocardiograms were performed on 36 (28%) patients. The appropriate use criteria were retrospectively applied, and indications for their performance were classified as "appropriate" (n = 4), "may be appropriate" (n = 17), or "rarely appropriate" (n = 15). Minor echocardiographic abnormalities were present in 22% (n = 8) of echocardiograms obtained for all appropriate use criteria classifications. No moderate or severe echocardiographic abnormalities were found. Incidental findings were noted in eight echocardiograms. CONCLUSION: Echocardiography in the evaluation of "rarely appropriate" and "may be appropriate" palpitation-related indications is of low diagnostic yield.

Complicated Fusobacterium Sinusitis: A Case Report.

Fusobacterium infections and Lemierre syndrome are traditionally associated with pharyngitis. We report 3 cases of Fusobacterium sinusitis that resulted in Pott puffy tumor. One of these cases also had Lemierre Syndrome. We encourage expansion of the clinical spectrum of Lemierre syndrome to include complicated Fusobacterium sinusitis.

Contextual Modulation of Vocal Behavior in Mouse: Newly Identified 12 kHz "Mid-Frequency" Vocalization Emitted during Restraint.

While several studies have investigated mouse ultrasonic vocalizations (USVs) emitted by isolated pups or by males in mating contexts, studies of behavioral contexts other than mating and vocalization categories other than USVs have been limited. By improving our understanding of the vocalizations emitted by mice across behavioral contexts, we will better understand the natural vocal behavior of mice and better interpret vocalizations from mouse models of disease. Hypothesizing that mouse vocal behavior would differ depending on behavioral context, we recorded vocalizations from male CBA/CaJ mice across three behavioral contexts including mating, isolation, and restraint. We found that brief restraint elevated blood corticosterone levels of mice, indicating increased stress relative to isolation. Further, after 3 days of brief restraint, mice displayed behavioral changes indicative of stress. These persisted for at least 2 days after restraint. Contextual differences in mouse vocal behavior were striking and robust across animals. Thus, while USVs were the most common vocalization type across contexts, the spectrotemporal features of USVs were context-dependent. Compared to the mating context, vocalizations during isolation and restraint displayed a broader frequency range, with a greater emphasis on frequencies below 50 kHz. These contexts also included more non-USV vocal categories and different vocal patterns. We identified a new Mid-Frequency Vocalization, a tonal vocalization with fundamental frequencies below 18 kHz, which was almost exclusively emitted by mice undergoing restraint stress. These differences combine to form vocal behavior that is grossly different among behavioral contexts and may reflect the level of anxiety in these contexts.
