Objective: This study was a prospective evaluation of surgical indications and outcomes for unilateral and bilateral bronchiectasis according to hemodynamic (functional and morphologic) classification.
Methods: Between January 1998 and January 2004, the morphologic features (cystic versus cylindric) by chest computed tomography and the hemodynamic features (perfused versus nonperfused) by lung ventilation/perfusion scan were determined in 66 patients with bronchiectasis (53 unilateral and 13 bilateral). The indication for surgical resection in both groups was the presence of localized areas of cystic, nonperfused bronchiectasis.
Results: In the unilateral bronchiectasis group, there were 28 female and 25 male patients with an average age of 37.5 +/- 3.8 years (range 6-40 years). Pneumonectomy was performed in 10 cases (8 left and 2 right), and lobectomy or bilobectomy was performed in 43. In the bilateral group, there were 7 male and 6 female patients with an average age of 42 +/- 5.4 years (range 9-55 years). Pneumonectomy was performed in 2 cases, lobectomy in 5, and bilateral staged lobectomy in 6. There was 1 postoperative death (1.5%), and morbidity was 18% (12 patients). Four patients required reexploration for bleeding, 4 had prolonged air leak develop, 3 acquired pulmonary infections, and 1 had localized empyema develop. During a mean follow-up of 52 months (range 24-82 months), 48 patients were considered cured (73%) and 17 had symptomatic improvement (26%). Pseudomonas infection and underlying chronic obstructive airway disease were poor prognostic factors (P < .05).
Conclusion: The hemodynamic (functional and morphologic) classification provides an accurate functional classification for bronchiectasis. Its application in determining the indications and extent of surgical resection is superior to morphologic classification alone. Curative resection can be achieved in both unilateral and bilateral bronchiectasis with acceptable morbidity.

Robust preclinical models of asymmetric ventricular loading in late gestation reflecting conditions such as hypoplastic left heart syndrome are lacking. We characterized the morphometry and microvascular function of the hypoplastic left ventricle (LV) and remaining right ventricle (RV) in a sham-controlled late gestation fetal lamb model of impaired left ventricular inflow (ILVI). Singleton fetuses were instrumented at ∼120 days gestational age (dGA; term is ∼147 days) with vascular catheters, an aortic flow probe and a deflated left atrial balloon.

The advancements in cardiovascular imaging over the past two decades have been significant. The miniaturization of ultrasound devices has greatly contributed to their widespread adoption in operating rooms and intensive care units. The integration of AI-enabled tools has further transformed the field by simplifying echocardiographic evaluations and enhancing the reproducibility of hemodynamic measurements, even for less experienced operators.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.

Diabetic kidney disease is a leading cause of kidney failure worldwide and is easily detectable with screening examination. Diabetes causes hyperfiltration and activation of the renin-angiotensin aldosterone system by hemodynamic changes within the nephron, which perpetuates damaging physiology. Diagnosis is often clinical after detection of heavy proteinuria in a patient with diabetes,but can be confirmed by observation of histologic stages on kidney biopsy.

Cardiovascular disease (CVD) is the leading cause of death for women worldwide. One of the risk factors for CVD in women is complications during pregnancy. Pregnancy complications include a wide arena of pathologies, including hypertension, preeclampsia, gestational diabetes, preterm delivery and miscarriage.
