Heart failure increases the risk of kidney disease progression. However, whether cardiac function and structure are associated with the risk of incident chronic kidney disease (CKD) is not well characterized in a community setting.

Among 4188 participants (mean age 75 years and 22% blacks) of the Atherosclerosis Risk in Communities Study without prevalent CKD in 2011-13, we examined the association of echocardiographic measures of left ventricular (LV) mass index, ejection fraction, left atrial volume index (LAVi), right ventricular (RV) fractional area change, and peak RV-right atrium (RA) gradient, with the subsequent risk of incident CKD, as defined by >25% decline to estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2, hospitalization with CKD diagnosis, or incident end-stage kidney disease. Multivariable Cox regression models were used to estimate hazard ratios (HRs). The risk of incident CKD was monotonically increased with each of higher LV mass index [adjusted HR 2.61 (1.92-3.55) fnd kidney health in older populations.
To assess the appropriateness of medication-related clinical decision support (CDS) alerts associated with renal insufficiency and the potential/actual harm from overriding the alerts.

Override rate frequency was recorded for all inpatients who had a renal CDS alert trigger between 05/2017 and 04/2018. Two random samples of 300 for each of 2 types of medication-related CDS alerts associated with renal insufficiency-"dose change" and "avoid medication"-were evaluated by 2 independent reviewers using predetermined criteria for appropriateness of alert trigger, appropriateness of override, and patient harm.

We identified 37100 "dose change" and 5095 "avoid medication" alerts in the population evaluated, and 100% of each were overridden. Dose change triggers were classified as 12.5% appropriate and overrides of these alerts classified as 90.5% appropriate. Avoid medication triggers were classified as 29.6% appropriate and overrides 76.5% appropriate. We identified 5 adverse drug events, and, of these, 4 of had previously been found to be the most clinically beneficial alerts in a legacy system, in this system they were ineffective. These findings underscore the need for improvements in alert design, implementation, and monitoring of alert performance to make alerts more patient-specific and clinically appropriate.This study examined the moderating influences of active social networks (ASN), sedentary social networks (SSN) and ASN lost on the relationship between neighbourhood walkability and social activity in community-dwelling older adults aged 60 years or more in Accra, Ghana. A total of 863 individuals participated after G*Power 3.1 was utilized to calculate the minimum sample size. We analysed the data with Pearson's correlation test and hierarchical linear regression models. Bevacizumab in vitro A sensitivity analysis was conducted to select the ultimate confounding variables. The study found a positive influence of neighbourhood walkability on social activity after the covariate adjustment (β = 0.18; t = 5.2; p = 0.000). The positive influence of neighbourhood walkability on social activity was significantly reduced by ASN lost and SSN. ASN did not have a significant moderating influence on the primary relationship. The study concludes that the positive influence of walkable neighbourhoods on social activity decreases as SSN and ASN lost increase.
Mediastinal neurogenic tumours are uncommon and often benign neoplasms mostly located in the posterior mediastinum and usually diagnosed incidentally. We reviewed our results after surgical resection. We compared patient characteristics and tumour nature between children and adults. Differences between thoracoscopic and open approach were analysed.

Departmental thoracic surgical database was queried for primary mediastinal neurogenic tumours resected between 1992 and 2017. Data included demographics, pathology, tumour nature, symptoms, surgical approach and postoperative morbidity/mortality.

Fifty-one patients (8 children and 43 adults) underwent tumour resection. Pathology revealed nerve sheath tumour in 1 child (12.5%) versus 36 adults (83.7%; P < 0.001) and ganglion cell tumour in 7 (87.5%) versus 5 (11.6%; P < 0.001). Two adults had a paraganglioma. Malignancy was present in 2 children (25%) versus 2 adults (4.6%; P = 0.049). All malignant tumours caused symptoms while most patients with benigiginating from the nerve sheath. The majority of patients with mediastinal neurogenic tumours are asymptomatic. Most tumours are amenable for thoracoscopic resection.This case is a 66-yr-old woman with a 2-mo history of left-sided tinnitus. Workup with magnetic resonance angiography showed early opacification of the left sigmoid sinus and internal jugular vein as well as asymmetric and abundant opacification of the left external carotid artery branches, suspicious for a dural arteriovenous fistula (dAVF). Diagnosis was confirmed with cerebral angiography, consistent with a left-sided Cognard type I dAVF.1 Initial treatment attempt was made with transarterial 6% ethylene-vinyl alcohol copolymer (Onyx 18) embolization of feeders from the occipital and middle meningeal arteries. However, embolization was not curative and there was a recurrence of a highly bothersome tinnitus 3 wk following treatment. Angiography redemonstrated the transverse sinus dAVF with new recruitment arising from several feeders, including the left external carotid artery, middle meningeal artery, and superficial temporal artery, now Cognard type IIa. Definitive treatment through a transvenous coil embolization provided permanent obliteration of the fistula without recrudescence of symptoms on follow-up. In this video, the authors discuss the nuances of treating a dAVF via a transvenous embolization. Patient consent was given prior to the procedure, and consent and approval for this operative video were waived because of the retrospective nature of this manuscript and the anonymized video material.On December 9th 2019, Whakaari / White Island volcano in New Zealand erupted with 47 people on the island. 31 people survived long enough to enter the New Zealand National Burn network - 13 were repatriated to Australia within 72 hours and 14 of the remaining 18 were treated at the National Burn Centre at Middlemore Hospital in Auckland. Our department has previously published a model to calculate the total operative requirements for any given burn surface area for the first four weeks of burn treatment. From this model we calculated the predicted surgical time and operative visit requirements for each patient and compared this to their actual requirements. Actual requirements were also recorded beyond four weeks until discharge. Results show average variance for operative minutes was significantly above predicted with both the full thickness burn model (average variance 3.24) and the electrical burn model (average variance 2.65). There was a wide range in both cases (0.54 to 6.17 and 0.44 to 5.06 respectively).
