ABSTRACT

Objectives: To determine the most common fetal ultrasound markers of total anomalous pulmonary venous return (TAPVR) during mid-trimester ultrasound using standardly obtained images and evaluate the performance of diagnostic algorithms for improving prenatal diagnosis. Methods: This was a matched case-control study at a regional referral centre (2005 to 2019). Cases of TAPVR were matched to controls 1 : 4 by date of birth and biologic sex. Postprocessing review of stored fetal ultrasound images was performed by two blinded and independent observers in a standardized fashion using nine sonographic markers: (i) left/right heart disproportion; (ii) abnormal distribution of great vessels; (iii) pulmonary vein entry into the left atrium (LA); (iv) confluence behind the LA; (v) abnormal coronary sinus; (vi) absence of the Coumadin ridge; (vii) aortic diameter; (viii) distance between LA and aorta; and (ix) post-LA space index >1.27. Descriptive and inferential statistics were used to present results and compare cases and controls. Diagnostic algorithms were compared by sensitivity/specificity. Results: 21 cases of isolated TAPVR were matched to 84 controls (n = 105). The most common ultrasound marker of TAPVR was absence of pulmonary vein entry into the LA (42.9%), followed by abnormal Coumadin ridge (38.1%). Cases of TAPVR had significantly larger post-LA spaces than controls (p < 0.0001) and wider aortic diameters (p=0.006). A diagnostic algorithm stratifying on absence of pulmonary veins followed by an abnormal Coumadin ridge, can correctly identify cases of TAPVR with high specificity (90.5%) and moderate sensitivity (61.9%). Conversely, a diagnostic algorithm using the presence of any 3 abnormal markers had improved specificity (94.1%) but poorer sensitivity (23.8%). Conclusions: Using standardly obtained images from routine fetal ultrasound, improved prenatal detection of isolated TAPVR is possible. A standardized diagnostic approach can be highly specific for fetal TAPVR, however, algorithms that are sufficiently sensitive for screening in the general population are still needed.

ABSTRACT

OBJECTIVES: To describe the paediatric transgender population accessing health care through the Manitoba Gender Dysphoria Assessment and Action for Youth (GDAAY) program, and report youth's experiences accessing health care in Manitoba. METHODS: Demographic, medical, surgical and mental health information was extracted from the medical records of youth referred to the GDAAY program (n=174). A 77-item online survey was conducted with a subset of those youth (n=25) to identify common health care experiences and perceptions of trans youth in Manitoba. RESULTS: Chart review of 122 natal females and 52 natal males, ranging in age from 4.7 to 17.8 years (mean 13.9 years), found 66 patients (46.8%) with a pre-existing or current mental health diagnosis, of which anxiety and depression were the most common (n=43, 30.5%). Qualitative self-reports revealed all patients had negative interactions with health care providers at some point, many having experienced lack of engagement with the medical system due to reported lack of knowledge by the provider on trans-related health services. CONCLUSION: Transgender youth in Manitoba seeking GDAAY services have high rates of anxiety and depression. These youth face adversity in health care settings and are distressed over long wait times for mental health services. Recommendations to improve care include increasing general health care providers' education on gender affirmative care, providing gender sensitivity training for health care providers, gathering preferred names and pronouns during triage, increasing visibility of support for LGBT+ persons in clinics, increasing resource allocation to this field and creating policies so all health care settings are safe places for trans youth.
