Acid-base and biochemical stabilization and quality of recovery in male cats with urethral obstruction and anesthetized with propofol or a combination of ketamine and diazepam

This study compared acid-base and biochemical changes and quality of recovery in male cats with experimentally induced urethral obstruction and anesthetized with either propofol or a combination of ketamine and diazepam for urethral catheterization. Ten male cats with urethral obstruction were enrolled for urethral catheterization and anesthetized with either ketamine-diazepam (KD) or propofol (P). Lactated Ringer's solution was administered by intravenous (IV) beginning 15 min before and continuing for 48 h after relief of urethral obstruction. Quality of recovery and time to standing were evaluated. The urethral catheter was maintained to measure urinary output. Hematocrit (Hct), total plasma protein (TPP), albumin, total protein (TP), blood urea nitrogen (BUN), creatinine, pH, bicarbonate (HCO3-), chloride, base excess, anion gap, sodium, potassium, and partial pressure of carbon dioxide in mixed venous blood (pvCO(2)) were measured before urethral obstruction, at start of fluid therapy (0 h), and at subsequent intervals. The quality of recovery and time to standing were respectively 4 and 75 min in the KD group and 5 and 16 min in the P group. The blood urea nitrogen values were increased at 0, 2, and 8 h in both groups. Serum creatinine increased at 0 and 2 h in cats administered KD and at 0, 2, and 8 h in cats receiving P, although the values were above the reference range in both groups until 8 h. Acidosis occurred for up to 2 h in both groups. Acid-base and biochemical stabilization were similar in cats anesthetized with propofol or with ketamine-diazepam. Cats that received propofol recovered much faster, but the ketamine-diazepam combination was shown to be more advantageous when treating uncooperative cats as it can be administered by intramuscular (IM) injection.Cette étude visait à comparer les changements biochimiques et acide-base ainsi que la qualité de la convalescence chez des chats mâles avec une\ud obstruction urétrale induite expérimentalement et anesthésiés avec soit du propofol ou une combinaison de kétamine et diazépam pour une\ud cathétérisation urétrale. Dix chats mâles avec une obstruction urétrale ont été recrutés pour cathétérisation urétrale et anesthésiés avec soit\ud une combinaison kétamine-diazépam (KD) ou du propofol (P). Une solution de lactate de Ringer a été administrée par voie intraveineuse (IV)\ud débutant 15 min avant et continuant 48 h après l’élimination de l’obstruction urétrale. La qualité de la convalescence et le délai avant de se\ud tenir debout ont été évalués. Le cathéter urinaire était laissé en place pour mesurer l’excrétion urinaire. Les valeurs des paramètres suivants\ud ont été mesurées avant l’obstruction urétrale, au début de la fluidothérapie (0 h) et à des intervalles subséquents : hématocrite (Hct), protéines\ud plasmatiques totales (TPP), albumine, protéines totales (TP), azotémie (BUN), créatinine, pH, bicarbonate (HCO3\ud 2), chlorure, excès de base,\ud trou anionique, sodium, potassium, pression partielle de dioxide de carbone dans le sang veineux (pvCO2). La qualité de la convalescence et\ud le temps avant de se tenir debout étaient respectivement de 4 et 75 minutes dans le groupe KD et de 5 et 16 minutes dans le groupe P. Les\ud valeurs de BUN étaient augmentées à 0, 2 et 8 h dans les deux groupes. La créatinine sérique augmenta à 0 et 2 h chez les chats recevant KD\ud et à 0, 2 et 8 h chez les chats recevant P, bien que les valeurs étaient supérieures à l’écart de référence dans les deux groupes jusqu’à 8 h. Une\ud acidose s’est produite pendant 2 h dans les deux groupes. L’équilibre acide-base et la stabilisation biochimique étaient similaires chez les chats\ud anesthésiés avec du propofol ou avec KD. Les chats qui ont reçu du propofol ont récupéré beaucoup plus rapidement, mais la combinaison KD\ud s’est avérée plus avantageuse pour traiter des chats non-coopératifs étant donné la possibilité d’administration par voie intra-musculaire

Preventive medical care in remote Aboriginal communities in the Northern Territory: a follow-up study of the impact of clinical guidelines, computerised recall and reminder systems, and audit and feedback

Background Interventions to improve delivery of preventive medical services have been shown to be effective in North America and the UK. However, there are few studies of the extent to which the impact of such interventions has been sustained, or of the impact of such interventions in disadvantaged populations or remote settings. This paper describes the trends in delivery of preventive medical services following a multifaceted intervention in remote community health centres in the Northern Territory of Australia. Methods The intervention comprised the development and dissemination of best practice guidelines supported by an electronic client register, recall and reminder systems and associated staff training, and audit and feedback. Clinical records in seven community health centres were audited at regular intervals against best practice guidelines over a period of three years, with feedback of audit findings to health centre staff and management. Results Levels of service delivery varied between services and between communities. There was an initial improvement in service levels for most services following the intervention, but improvements were in general not fully sustained over the three year period. Conclusions Improvements in service delivery are consistent with the international experience, although baseline and follow-up levels are in many cases higher than reported for comparable studies in North America and the UK. Sustainability of improvements may be achieved by institutionalisation of relevant work practices and enhanced health centre capacity

NUP98-fusion transcripts characterize different biological entities within acute myeloid leukemia: A report from the AIEOP-AML group.

In the last years, collaborative studies have joined to link the degree of genetic heterogeneity of acute myeloid leukemia (AML) to clinical outcome,1, 2 allowing risk stratification before therapy and guiding post-induction treatment of children with AML. So far, still half of these patients, whose disease is usually characterized by a grim prognosis, lack a known biomarker offering opportunities of targeted treatment

Determinants of postnatal spleen tissue regeneration and organogenesis

Abstract The spleen is an organ that filters the blood and is responsible for generating blood-borne immune responses. It is also an organ with a remarkable capacity to regenerate. Techniques for splenic auto-transplantation have emerged to take advantage of this characteristic and rebuild spleen tissue in individuals undergoing splenectomy. While this procedure has been performed for decades, the underlying mechanisms controlling spleen regeneration have remained elusive. Insights into secondary lymphoid organogenesis and the roles of stromal organiser cells and lymphotoxin signalling in lymph node development have helped reveal similar requirements for spleen regeneration. These factors are now considered in the regulation of embryonic and postnatal spleen formation, and in the establishment of mature white pulp and marginal zone compartments which are essential for spleen-mediated immunity. A greater understanding of the cellular and molecular mechanisms which control spleen development will assist in the design of more precise and efficient tissue grafting methods for spleen regeneration on demand. Regeneration of organs which harbour functional white pulp tissue will also offer novel opportunities for effective immunotherapy against cancer as well as infectious diseases

Psychological treatments and psychotherapies in the neurorehabilitation of pain. Evidences and recommendations from the italian consensus conference on pain in neurorehabilitation

BACKGROUND: It is increasingly recognized that treating pain is crucial for effective care within neurological rehabilitation in the setting of the neurological rehabilitation. The Italian Consensus Conference on Pain in Neurorehabilitation was constituted with the purpose identifying best practices for us in this context. Along with drug therapies and physical interventions, psychological treatments have been proven to be some of the most valuable tools that can be used within a multidisciplinary approach for fostering a reduction in pain intensity. However, there is a need to elucidate what forms of psychotherapy could be effectively matched with the specific pathologies that are typically addressed by neurorehabilitation teams. OBJECTIVES: To extensively assess the available evidence which supports the use of psychological therapies for pain reduction in neurological diseases. METHODS: A systematic review of the studies evaluating the effect of psychotherapies on pain intensity in neurological disorders was performed through an electronic search using PUBMED, EMBASE, and the Cochrane Database of Systematic Reviews. Based on the level of evidence of the included studies, recommendations were outlined separately for the different conditions. RESULTS: The literature search yielded 2352 results and the final database included 400 articles. The overall strength of the recommendations was medium/low. The different forms of psychological interventions, including Cognitive-Behavioral Therapy, cognitive or behavioral techniques, Mindfulness, hypnosis, Acceptance and Commitment Therapy (ACT), Brief Interpersonal Therapy, virtual reality interventions, various forms of biofeedback and mirror therapy were found to be effective for pain reduction in pathologies such as musculoskeletal pain, fibromyalgia, Complex Regional Pain Syndrome, Central Post-Stroke pain, Phantom Limb Pain, pain secondary to Spinal Cord Injury, multiple sclerosis and other debilitating syndromes, diabetic neuropathy, Medically Unexplained Symptoms, migraine and headache. CONCLUSIONS: Psychological interventions and psychotherapies are safe and effective treatments that can be used within an integrated approach for patients undergoing neurological rehabilitation for pain. The different interventions can be specifically selected depending on the disease being treated. A table of evidence and recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation is also provided in the final part of the pape

"Mapping the Discourse. Architecture Periodicals in/for the Teaching of Architecture History/ Une cartographie du discours. Périodiques d’architecture dans/pour l’enseignement de l’histoire de l’architecture".

The article reflects on a pedagogical project conducted in the framework of the History and Theory course at Politecnico di Milano and questions the value of architectural journals as sources, instruments, methods, and narrative devices for the teaching of architectural history, probing their role as mediators with multifaceted networks of professional, intellectual, and institutional milieux involved in the production of architectural knowledge. The study was conducted on a corpus of around fifty periodicals addressed as a “system of knowledge”, crossing diverse genres and generations of journals, and questioning their character of “complex social objects” to be investigated in their material, economic, cultural, and visual dimensions. On the one hand, the method combining “journal biographies” with the decoding of the issues through the analysis of all their structuring parts allows questioning the changing notion of milieu that magazines contribute to creating over time, revealing the interrelations between a constellation of agents - editors, owners, institutions, and audience – with their divergent agendas, rationalities, and editorial strategies. On the other hand, the paper reflects on the significance of analyzing journals in their interconnections, as cross-cultural and comparative readings offer a more nuanced understanding of the times and forms of production of architectural culture as a transnational practice, challenging the canonical interpretations and time frames of a 20th-century architectural history still centered on the European and North American editorial scene
