Anatomical classification of canine congenital extrahepatic portosystemic shunts based on CT angiography: A SVSTS and VIRIES multi-institutional study in 1082 dogs
No full textCanine congenital extrahepatic portosystemic shunt (EHPSS) morphologies have not been fully elucidated. The goal of this retrospective, multi-institutional study was to use CT angiography to create an anatomical-based nomenclature system for canine congenital EHPSS. These shunt morphologies were then evaluated to identify any significant association with patient age, sex, breed, weight, or subjective portal perfusion score. Data collected respectively from the SVSTS and VIRIES list-serves included patient DOB, sex, breed, weight, CT date, and reported diagnosis. A single author (C.W.) viewed all CT scans and classified shunts based on the shunt portal vessel(s) of origin, the shunt systemic vessel(s) of insertion, and any substantial portal vessels contributing to the shunt. Additionally, hepatic portal perfusion was subjectively scored between one (poor/none) and five (good/normal) based on the caliber of the intrahepatic portal veins. A total of 1182 CT scans were submitted from 13 different institutions. Due to exclusion criteria, 100 (8.5%) were removed, leaving 1082 CT scans to be included. Forty-five different EHPSS anatomies were identified with five classifications accounting for 85% of all shunts (left gastric-phrenic [27%], left gastric-azygos [19%], left gastric-caval [15%], aberrant left gastric-caval with right gastric vein [12%], and aberrant left gastric-caval with right gastric vein and short gastric vein [11%]). Shunt origin involved the left gastric vein in 95% of the described classifications. Significant differences were identified among the five most common shunt types with respect to age at the time of the CT scan (P < .001), sex (P = .009), breed (P < .001), weight (P < .001), and subjective portal perfusion score (P < .001). An anatomical classification system for canine EHPSS may enable improved understanding, treatment comparisons, and outcome prediction for these patients
Anatomical classification of feline congenital extrahepatic portosystemic shunts based on CT angiography: A SVSTS and VIRIES multi-institutional study in 231 cats.:Anatomical Classification of Feline Congenital EHPSS Based on CT Angiography
No full textThe prevalence of anatomical-based subtypes of feline congenital extrahepatic portosystemic shunts (EHPSS) has not been completely elucidated. The goal of this study was to use CT angiography to create an anatomical-based nomenclature system for feline congenital EHPSS. Additionally, subjective portal perfusion scores were generated to determine if intrinsic portal vein development was associated with different shunt conformations or patient age at the time of CT. The SVSTS and VIRIES list services were used to recruit cases. Data collected included patient DOB, gender, breed, weight, CT date, and reported diagnosis. Shunts were classified based upon (1) the shunt portal vessel(s) of origin, (2) the shunt systemic vessel(s) of insertion, and (3) any substantial portal vessels contributing to the shunt. Additionally, hepatic portal perfusion was subjectively scored between 1 (poor/none) and 5 (good/normal) based on the caliber of the intrahepatic PVs. A total of 264 CT scans were submitted from 29 institutions. Due to exclusion criteria, 33 (13%) were removed, leaving 231 CT scans to be included. Twenty-five different EHPSS anatomies were identified with five classifications accounting for 78% of all shunts (LGP [53%], LGC-post [11%], LCG [7%], LGC-pre [4%], and PC [4%]). Shunt origin involved the left gastric vein in 75% of the described classifications. Significant differences were identified among the five most common shunt types with respect to age at the time of CT scan (P =.002), breed (P <.001), and subjective portal perfusion score (P <.001). This refined anatomical classification system for feline EHPSS may enable improved understanding, treatment comparisons, and outcome prediction for cats with these anomalies.</p
“Types and components of urban blue spaces that have a positive impact on mental health and well-being: a systematic review”
No full text“EKLIPSE Mental Health and Green and Blue open spaces" è un progetto sul tema della valutazione dell’impatto sulla salute mentale e il benessere delle persone degli spazi aperti urbani “verdi e blu”, anche mediante l’individuazione di criteri e indicatori prestazionali nel confronto con le sfide poste alla salute dal cambiamento climatico (ricerca in corso). EKLIPSE è un progetto Horizon 2020 finanziato dall'Unione europea che punta a migliorare l'interfaccia tra scienza, politica e società. I gruppi di lavoro di esperti istituiti da EKLIPSE svolgono attività di ricerca rivolta a soddisfare le richieste di conoscenze da parte dei responsabili politici. Il gruppo di lavoro coordinato da Maria Beatrice Andreucci con Annamaria Lammel (Université Paris 8) e Sjerp de Vries (Wageningen University and Research) sta lavorando dal 2017 a una richiesta presentata dal gruppo di lavoro Biodiversity & Health del 3rd French Plan on Health and Environment (PNSE3) – del Ministero dell’Ambiente francese (MTES) in cofinanziamento con l’Organizzazione Mondiale della Sanità. Tale approccio è stato identificato per promuovere l’utilizzo delle NBS nei progetti finanziati nell’ambito di H2020, con l’obiettivo di incrementare la resilienza umana al cambiamento climatico, costruendo una base di evidenza scientifica in termini di benefici prodotti dagli spazi aperti
Travelling Wave Solutions of a Time Regularised Long Wave Equation Associated With the Korteweg-de Viries Equation in Fluid Dynamics
No full textIn this paper, we investigate the physical significance of the time regularised long wave (TRLW) equation within the realm of mathematics. Other varieties of travelling wave solutions to the analysed problem in hyperbolic form are looked at using the (1/G′)-expansion method. Physically, the singular point’s shock wave structure offers the framework for asymptotic mathematics analyses. It offers a scientific perspective on the phenomenon of non-linear propagation. By giving particular values to constants in solutions, 3-D, contour, and 2-D graphs can depict the state of the wave at any given time
