Prevalence of potential retrograde embolization pathways in the proximal descending aorta in stroke patients and controls.

BACKGROUND Retrograde diastolic blood flow in the proximal descending aorta (DAo) connecting complex plaques (≥4 mm thick) with brain-supplying supra-aortic arteries may constitute a source of stroke. Yet, data only from high-risk populations (cryptogenic stroke patients with aortic atheroma≥3 mm) regarding the prevalence of this potential stroke mechanism are available. We aimed to quantify the frequency of this mechanism in unselected patients with cryptogenic stroke after routine diagnostics and controls without a history of stroke. METHODS 88 patients (67 stroke patients, 21 cardiac controls) were prospectively included. 3D T1-weighted bright blood MRI of the aorta was applied for the detection of complex DAo atheroma. ECG-triggered and navigator-gated 4D flow MRI allowed measuring time-resolved 3D blood flow in vivo. Potential retrograde embolization pathways were defined as the co-occurrence of complex plaques and retrograde blood flow in the DAo reaching the outlet of (a) the left subclavian artery, (b) the left common carotid artery, or/and (c) the brachiocephalic trunk. The frequency of these pathways was analyzed by importing 2D plaque images into 3D blood flow visualization software. RESULTS Complex DAo plaques were more frequent in stroke patients (44 in 31/67 patients (46.3%) vs. 5 in 4/21 controls (19.1%); p=0.039), especially in older patients (29/46 (63.04%) patients≥60 years of age with 41 plaques vs. 2/21 (9.14%) patients<60 years of age with 3 plaques; p<0.001). Contrary to our assumption, retrograde diastolic blood flow at the DAo occurred in every patient irrespective of the existence of plaques with a similar extent in both groups (26±14 vs. 32±18 mm; p=0.114). Therefore, only the higher prevalence of complex DAo plaques in stroke patients resulted in a three times higher frequency of potential retrograde embolization pathways compared to controls (22/67 (32.8%) vs. 2/21 (9.5%) controls; p=0.048). CONCLUSIONS This study revealed that retrograde flow in the descending aorta is a common phenomenon not only in stroke patients. The existence of potential retrograde embolization pathways depends mainly on the occurrence of complex plaques in the area 0 to ∼30 mm behind the outlet of the left subclavian artery, which is exposed to flow reversal. In conclusion, we have shown that the frequency of potential retrograde embolization pathways was significantly higher in stroke patients suggesting that this mechanism may play a role in retrograde brain embolism.

Institutions for sustainable governance of forests: Equity, robustness and cross-level interactions in Mawlyngbna, Meghalaya, India

This study adopts Ostrom’s Social-Ecological Systems (SES) framework in empirical fieldwork to explain how local forestry institutions affect forest ecosystems and social equity in the community of Mawlyngbna in North-East India. Data was collected through 26 semi-structured interviews, participatory timeline development, policy documents, direct observation, periodicals, transect walks, and a concurrent forest-ecological study in the village. Results show that Mawlyngbna's forests provide important sources of livelihood benefits for the villagers. However, ecological disturbance and diversity varies among the different forest ownership types and forest-based livelihood benefits are inequitably distributed. Based on a bounded rationality approach, our analysis proposes a set of causal mechanisms that trace these observed social-ecological outcomes to the attributes of the resource system, resource units, actors and governance system. We analyse opportunities and constraints of interactions between the village, regional, and state levels. We discuss how Ostrom’s design principles for community-based resource governance inform the explanation of robustness but have a blind spot in explaining social equity. We report experiences made using the SES framework in empirical fieldwork. We conclude that mapping cross-level interactions in the SES framework needs conceptual refinement and that explaining social equity of forest governance needs theoretical advances.

Incidence of Gallstone Formation and Cholecystectomy 10 Years After Bariatric Surgery.

PURPOSE Rapid weight loss is a risk factor for gallstone formation, and postoperative treatment options for gallstone formation are still part of scientific discussion. No prospective studies monitored the incidence for gallstone formation and subsequent cholecystectomy after bariatric surgery longer than 5 years. The aim of the study was to determine the incidence of gallstone formation and cholecystectomy in bariatric patients over 10 years. MATERIALS AND METHODS One hundred nine patients were observed over 10 years after laparoscopic gastric banding or gastric bypass/gastric sleeve. The incidence of gallstone formation and cholecystectomy was correlated to longitudinal changes in anthropometric parameters. RESULTS In total, 91 female and 18 male patients were examined. Nineteen patients had postoperative gallstone formation, and 12 female patients required cholecystectomy. The number needed to harm for gallstone formation was 7.1 and 2.3 cases in the banding group and gastric bypass/gastric sleeve group, respectively. The number needed to harm for cholecystectomy was 11.6 and 2.5 cases in the banding group and the gastric bypass/gastric sleeve group, respectively. Weight loss was higher in patients requiring subsequent cholecystectomy. Mean follow-up to cholecystectomy was 21.5 months with the latest operation after 51 months. CONCLUSION Female gender and rapid weight loss were major risk factors for postoperative cholelithiasis. Ultrasound examinations within 2 to 5 years are recommended in every patient, independent of bariatric procedure. Pharmacologic treatment should be considered in high risk patients within 2 to 5 years to prevent postoperative cholelithiasis. This helps to optimize patient care and lowers postoperative morbidity.
