Medical and surgical management of gallbladder sludge and mucocoele development in a Miniature Schnauzer

The factors enhancing mucocoele development in dogs remain poorly understood. A 7-year-old female spayed Miniature Schnauzer was presented to the Massey University Veterinary Teaching Hospital for progressive lethargy, inappetance and abdominal discomfort. Initial physical examination findings revealed a moderate degree of cranial abdominal pain, with subsequent diagnostic tests confirming the patient as having diabetes mellitus, with a concurrent marked hypertriglyceridaemia. In an attempt to localise the source of pain, an ultrasound examination of the abdomen was performed, revealing a marked degree of gallbladder sludge. With appropriate medical management including ursodeoxycholic acid and insulin therapy, the patient stabilised and was discharged. With persistence of clinical signs three months later, progression of the gallbladder sludge towards mucocoele development was suspected. Exploratory laparotomy was instigated, and an emergency cholecystectomy was performed. This case report therefore entails a suspected gallbladder mucocoele that developed in a diabetic patient with previously diagnosed biliary sludge. A unique feature of this case report is the presence of diabetes mellitus, which has been suggested to be a causative factor in the development of gallbladder mucocoeles. It is also hypothesised that gallbladder sludge and mucocoeles are associated, however it is yet to be ascertained whether this association is causal or contributory. The authors examined the possible relationship between this endocrinopathy and biliary sludge, and their possible effects on mucocoele development. Specific associated factors to sludge formation are also examined. The medical and surgical management of gallbladder mucocoeles is discussed

Multidimensional Flow Cytometry for Testing Blood-Handling Medical Devices

Blood handling devices such as left ventricular assist devices and total artificial hearts offer life-saving treatments for patients suffering from severe heart failure. Current devices have clinically proven that heart assist pumps are a safe and effective therapy, and indeed in many cases they are the only available method of treatment. However, current devices cause side effects including stroke, bleeding, infection, and thrombosis, preventing the technology from reaching its full potential. If the side effects could be reduced, then more patients could benefit from these devices. The complications are related to damage to blood cells and proteins as a result of contact with foreign materials and mechanical stress. There is a need for better devices with minimal blood impact to enable more patients to be safely treated; better tools, especially flow cytometry, could support the device development life cycle. In this chapter we review the clinical, in vivo, and in vitro flow cytometry data available for ventricular assist devices, conduct a gap analysis, and identify areas of future possibilities for device developers to establish new flow cytometry-based methodologies

What Can Go Wrong When Everything is Right? Using Organizational Justice to Understand Police Misconduct and Improve Personnel Systems

Despite decades of attention paid to police reform, cases of office misconduct still continue to plague policing organizations. Assuming that organizations may still experience such officer malfeasance even when attempting to pursue best practices, we aim to explore how things can go wrong when everything else seems right. Specifically, we rely on trickle-down models of organizational justice, group engagement, and social identity to articulate how otherwise desirable organizational outcomes may produce detrimental outgroup biases. Based on our theoretical premise, we articulate specific changes that may be made to personnel systems that can avoid such officer misconduct in policing contexts

Anorexia Nervosa, Major Depression, and Suicide Attempts: Shared Genetic Factors

We evaluated the extent to which genetic and environmental factors influenced anorexia nervosa (AN), major depressive disorder (MDD), and suicide attempts (SA). Participants were 6,899 women from the Swedish Twin study of Adults Genes and Environment. A Cholesky decomposition assessed independent and overlapping genetic and environmental contributions to AN, MDD, and SA. Genetic factors accounted for a substantial amount of liability to all three traits; unique environmental factors accounted for most of the remaining liability. Shared genetic factors may underlie the co-expression of these traits. Results underscore the importance of assessing for signs of suicide among individuals with AN

Influences on Patient Satisfaction in Healthcare Centers: A Semi-Quantitative Study Over 5 Years

BACKGROUND: Knowledge of ambulatory patients\u27 satisfaction with clinic visits help improve communication and delivery of healthcare. The goal was to examine patient satisfaction in a primary care setting, identify how selected patient and physician setting and characteristics affected satisfaction, and determine if feedback provided to medical directors over time impacted patient satisfaction. METHODS: A three-phase, semi-quantitative analysis was performed using anonymous, validated patient satisfaction surveys collected from 889 ambulatory outpatients in 6 healthcare centers over 5-years. Patients\u27 responses to 21 questions were analyzed by principal components varimax rotated factor analysis. Three classifiable components emerged: Satisfaction with Physician, Availability/Convenience, and Orderly/Time. To study the effects of several independent variables (location of clinics, patients\u27 and physicians\u27 age, education level and duration at the clinic), data were subjected to multivariate analysis of variance (MANOVA).. RESULTS: Changes in the healthcare centers over time were not significantly related to patient satisfaction. However, location of the center did affect satisfaction. Urban patients were more satisfied with their physicians than rural, and inner city patients were less satisfied than urban or rural on Availability/Convenience and less satisfied than urban patients on Orderly/Time. How long a patient attended a center most affected satisfaction, with patients attending \u3e10 years more satisfied in all three components than those attending60 years old. Patients were significantly more satisfied with their 30-40 year-old physicians compared with those over 60. On Orderly/Time, patients were more satisfied with physicians who were in their 50\u27s than physicians \u3e60. CONCLUSIONS: Improvement in patient satisfaction includes a need for immediate, specific feedback. Although Medical Directors received feedback yearly, we found no significant changes in patient satisfaction over time. Our results suggest that, to increase satisfaction, patients with lower education, those who are sicker, and those who are new to the center likely would benefit from additional high quality interactions with their physicians

Clinical translation of [18F]ICMT-11 for measuring chemotherapy-induced caspase 3/7 activation in breast and lung cancer

Background: Effective anticancer therapy is thought to involve induction of tumour cell death through apoptosis and/or necrosis. [18F]ICMT-11, an isatin sulfonamide caspase-3/7-specific radiotracer, has been developed for PET imaging and shown to have favourable dosimetry, safety, and biodistribution. We report the translation of [18F]ICMT-11 PET to measure chemotherapy-induced caspase-3/7 activation in breast and lung cancer patients receiving first-line therapy. Results: Breast tumour SUVmax of [18F]ICMT-11 was low at baseline and unchanged following therapy. Measurement of M30/M60 cytokeratin-18 cleavage products showed that therapy was predominantly not apoptosis in nature. While increases in caspase-3 staining on breast histology were seen, post-treatment caspase-3 positivity values were only approximately 1%; this low level of caspase-3 could have limited sensitive detection by [18F]ICMT-11-PET. Fourteen out of 15 breast cancer patients responded to first–line chemotherapy (complete or partial response); one patient had stable disease. Four patients showed increases in regions of high tumour [18F]ICMT-11 intensity on voxel-wise analysis of tumour data (classed as PADS); response was not exclusive to patients with this phenotype. In patients with lung cancer, multi-parametric [18F]ICMT-11 PET and MRI (diffusion-weighted- and dynamic contrast enhanced-MRI) showed that PET changes were concordant with cell death in the absence of significant perfusion changes. Conclusion: This study highlights the potential use of [18F]ICMT-11 PET as a promising candidate for non-invasive imaging of caspase3/7 activation, and the difficulties encountered in assessing early-treatment responses. We summarize that tumour response could occur in the absence of predominant chemotherapy-induced caspase-3/7 activation measured non-invasively across entire tumour lesions in patients with breast and lung cancer

Incidence and Cost of Acute Kidney Injury in Hospitalized Patients with Infective Endocarditis

Acute kidney injury (AKI) is a frequent complication of hospitalized patients with infective endocarditis (IE). Further, AKI in the setting of IE is associated with high morbidity and mortality. We aimed to examine the incidence, clinical parameters, and hospital costs associated with AKI in hospitalized patients with IE in an endemic area with an increasing prevalence of opioid use. This retrospective cohort study included 269 patients admitted to a major referral center in Kentucky with a primary diagnosis of IE from January 2013 to December 2015. Of these, 178 (66.2%) patients had AKI by Kidney Disease Improving Global Outcomes (KDIGO) serum creatinine criteria: 74 (41.6%) had AKI stage 1 and 104 (58.4%) had AKI stage ≥ 2. In multivariable analysis, higher comorbidity scores and the need for diuretics were independently associated with AKI, while the involvement of the tricuspid valve and the need for vasopressor/inotrope support were independently associated with severe AKI (stage ≥ 2). The median total direct cost of hospitalization was progressively higher according to each stage of AKI ($17,069 for no AKI;$37,111 for AKI stage 1; and $61,357 for AKI stage ≥ 2; p \u3c 0.001). In conclusion, two-thirds of patients admitted to the hospital due to IE had incident AKI. The occurrence of AKI significantly increased healthcare costs. The higher level of comorbidity, the affection of the tricuspid valve, and the need for diuretics and/or vasoactive drugs were associated with severe AKI in this susceptible population
