To study the efficiency of internal compression therapy (ICT), a new and promising method of treatment for deep venous insufficiency, how that efficiency is achieved, and its potential side-effects, in a porcine model.
The femoral vein diameters of 4 pigs were first measured. ICT was then applied such as to reduce the diameter of these veins by 50%. The femoral vein diameters of 2 pigs were re-measured after 1 month. The femoral vein and its surrounding tissue were excised for immunohistopathological and genetic examination. The same procedures were applied to the remaining 2 pigs 3 months subsequently. Collagen I and IV immunohistochemical staining and Masson's trichrome and Alcian blue histochemical staining were applied during immunohistopathological examination. Collagen I, III, and IV and connective tissue growth factor (CTGF) mRNA expressions were examined for genetic examination.
The femoral vein diameters decreased by approximately 50% after ICT application. This decrease persisted after the first and third months. Histopathological examination revealed loose connective tissue around the venous tissue after the operation, particularly in the third month, together with perivascular fibrosis and increased collagen in connective tissue. No difference was observed between regions with and without ICT application in terms of mucinous degeneration, an indicator of tissue injury, during Alcian blue staining. Genetic examination revealed an increase in collagen I and IV and CTGF mRNA expression in perivascular tissue resulting from ICT application.
ICT is effective both in terms of creating a durable tissue around the vein and of increasing collagen tissue and stimulating fibrosis, and has no deleterious side-effects on tissue.

In part a dialogic response to a study reflecting upon the impact of an academic's suicide, this multiple case study focuses on organizational and personal reactions to the deaths of four coworkers at four Polish universities. To present the experiences of the participants in a holistic manner, this study is phenomenological in design, incorporating semi-structured interviews followed by thematic data explicitation. Eight thematic areas were explored yielding results that diverge from most guidelines on the constructive management of loss in the workplace.
Although feline mammary carcinomas (FMCs) are highly metastatic, the literature and treatment options pertaining to advanced tumours are scarce. This study aimed to investigate the clinical outcome of metastatic FMC with or without adjuvant treatment.
The medical records of 73 cats with metastatic FMC (stage IV) were reviewed and included in this study. NVL-655 order Metastatic disease was detected by distinct imaging techniques (radiography, ultrasound and CT) and confirmed by cytology and/or histopathology. Cats with adjuvant chemotherapy treatment (n = 34) were divided into three groups group 1 (n = 9) cats receiving maximum tolerated dose chemotherapy; group 2 (n = 15) cats receiving metronomic chemotherapy; and group 3 (n = 10) cats treated with toceranib phosphate. The study endpoints were time to progression (TTP) and tumour-specific survival (TSS). Treatment-related toxicity was evaluated according to the Veterinary Co-operative Oncology Group's Common Terminology Criteria for Adverse Events version 1.1 (VCOG-CTCAE).
Overall mean TTP and TSS were 23 and 44 days, respectively. Cats with clinical signs at the time of diagnosis had a lower TSS (14 days) than asymptomatic cats (128 days;
<0.001). Cats with pleural effusion had a lower TSS (16 days) than cats without (
<0.001). Median TSS was 58, 75 and 63 in groups 1, 2 and 3, respectively (
= 0.197). Toxicity was observed in 66.7%, 20% and 30% of cats in groups 1, 2 and 3, respectively.
To the best of our knowledge, this study includes the highest number of patients with metastatic FMC assessed. Despite the overall poor prognosis, some cats survived >6 months, indicating that adjuvant treatment may be an option to consider in metastatic disease. More studies are warranted for better understanding and management of stage IV patients.

Glucose monitoring is an integral part of diabetes management. Interstitial glucose monitoring systems are increasingly commonly being used for this purpose in dogs and cats, including the use of a flash glucose monitoring system (FGMS). The aim of this study was to describe the incidence and nature of complications associated with the use of an FGMS in diabetic cats.
The medical records of all cats that had placement of a 14-day FGMS during a 1-year period were retrospectively reviewed. Data retrieved included the number of days the sensor remained attached and functional, location of sensor placement and complications associated with the sensor. Complications were defined as early sensor detachment, sensor failure prior to the end of the 14-day monitoring period and dermatologic changes at the sensor site. Descriptive statistics were used to characterize the data.
Twenty cats had a total of 33 FGMSs placed. The majority (30/33 [91%]) of sensors were placed over the dorsolateral aspect of the thorax just caudal to the scapula. Twenty (61%) FGMSs remained attached and functional for the full 14 days. The overall incidence of complications associated with FGMS use was 10/33 (30%). The most frequent complication was early sensor detachment (n = 5/33 [15%]). Mild dermatologic changes (erythema, crusts) were noted with 4/33 (12%) FGMSs. More serious complications (skin erosions, abscess formation) were noted with 2/33 (6%) FGMSs.
The use of the FGMS is relatively safe in cats, although there are potential complications that owners should be made aware of.
