Neoplasia-associated wasting diseases with economic relevance in the sheep industry
We review three neoplastic wasting diseases affecting sheep generally recorded under common production cycles and with epidemiological and economic relevance in sheep-rearing countries: small intestinal adenocarcinoma (SIA), ovine pulmonary adenocarcinoma (OPA) and enzootic nasal adenocarcinoma (ENA). SIA is prevalent in Australia and New Zealand but present elsewhere in the world. This neoplasia is a tubular or signet-ring adenocarcinoma mainly located in the middle or distal term of the small intestine. Predisposing factors and aetiology are not known, but genetic factors or environmental carcinogens may be involved. OPA is a contagious lung cancer caused by jaagsiekte sheep retrovirus (JSRV) and has been reported in most sheep-rearing countries, resulting in significant economic losses. The disease is clinically characterized by a chronic respiratory process as a consequence of the development of lung adenocarcinoma. Diagnosis is based on the detection of JSRV in the tumour lesion by immunohistochemistry and PCR. In vivo diagnosis may be difficult, mainly in preclinical cases. ENA is a neoplasia of glands of the nasal mucosa and is associated with enzootic nasal tumour virus 1 (ENTV-1), which is similar to JSRV. ENA enzootically occurs in many countries of the world with the exception of Australia and New Zealand. The pathology associated with this neoplasia corresponds with a space occupying lesion histologically characterized as a low-grade adenocarcinoma. The combination of PCR and immunohistochemistry for diagnosis is advised
Correlation of prostatic artery blood flow assessed by doppler ultrasonography with semen characteristics in beagle dogs
Pulsed-wave Doppler ultrasonography (PwD) is a method used to rapidly and noninvasively assess blood flow dynamics of the canine prostate. Modifications in gland vascularization can affect seminal plasma production and consequently sperm quality. The aim of this study was to determine the normal blood flow parameters of the prostate artery in beagle dogs and to analyze the correlations between vascular flow and semen quality characteristics. PwD was performed on five beagle dogs (5–6 years) measuring vascular features in four different locations of the prostatic artery (cranial, subcapsular, parenchymal and caudal); the measured features were peak systolic velocity (PSV), end-diastolic velocity (EDV), resistive index (RI) and pulsatility index (PI). Ejaculates were obtained using digital manipulation and semen quality was evaluated by determining macroscopic (total volume, sperm-rich fraction volume, color and pH) and microscopic (sperm motility, morphology, viability and acrosome integrity) characteristics. The values of PSV, PI and RI in cranial and caudal prostatic arteries were significantly higher than in subcapsular and parenchymal arteries (p < 0.05). Moreover. a positive correlation of PSV value in the cranial region of the prostatic artery with total ejaculate volume (p < 0.01, r = 0.612) and sperm concentration (p < 0.01, r = 0.587) was determined. PI index was negatively correlated with sperm concentration (p < 0.01, r = -0.709). In conclusion. the results suggest that the prostatic artery blood flow parameters can affect macroscopic semen quality characteristics in healthy dogs

Allogeneic adipose tissue-derived mesenchymal stem cells in ischaemic stroke (AMASCIS-02): A phase IIb, multicentre, double-blind, placebo-controlled clinical trial protocol
Introduction Stroke is a serious public health problem, given it is a major cause of disability worldwide despite the spread of recanalisation therapies. Enhancement of brain plasticity with stem cell administration is a promising innovative therapy to reduce sequelae in these patients. Methods and analysis We have developed a phase IIb, multicentre, randomised, double-blind, placebo-controlled clinical trial protocol to evaluate the safety and efficacy of intravenous administration of allogeneic adipose tissue-derived mesenchymal stem cells (AD-MSCs) in patients with acute ischaemic stroke, concurrently with conventional stroke treatment. Thirty patients will be randomised on a 1:1 basis to receive either intravenous placebo or allogeneic AD-MSCs as soon as possible within the first 4 days from stroke symptom onset. Patients will be followed up to 24 months after randomisation. The primary objective is the safety assessment of early intravenous administration of allogeneic AD-MSCs by reporting all adverse events and neurological or systemic complications in both treatment groups. Secondary objectives assess efficacy of early intravenous AD-MSC treatment in acute ischaemic stroke by evaluating changes in the modified Rankin Scale and the National Institutes of Health Stroke Scale throughout the follow-up period. In addition, brain repair biomarkers will be measured at various visits. Ethics and dissemination This clinical trial has been approved by the Clinical Research Ethics Committee of La Paz University Hospital (Madrid, Spain) and by the Spanish Agency of Medication and Health Products and has been registered in Eudra CT (2019-001724-35) and ClinicalTrials.gov (NCT04280003). Study results will be disseminated through peer-reviewed publications in Open Access format and at conference presentationsThis clinical trial has been promoted by the La Paz University Hospital Institute for Health Research—IdiPAZ (La Paz University Hospital—Universidad Autónoma de Madrid) and sponsored from a competitive grant from the Carlos III Health Institute Healthcare Research Fund, and cofunded by the European Regional Development Fund (ERDF) 'A way to make Europe'/'Investing in your future' (PIC18/00016).

Appropriate use of red blood cell transfusion in emergency departments: A study in five emergency departments
BACKGROUND:
Transfusion of blood components continues to be an important therapeutic resource into the 21st century. Between 5 and 58% of transfusions carried out are estimated to be unnecessary. According to several studies, at least 20% of packed red blood cell transfusions (RBCT) are administered in hospital emergency departments (ED), but few data are available about the appropriateness of RBCT in this setting. This multicentre, cross-sectional observational study aims to assess the appropriateness of RBCT indications and transfused volumes in patients who attend ED.
MATERIALS AND METHODS:
The study cohort is made up of consecutive consenting adult patients (≥18 years old) who received RBCT in ED over a 3-month period and for whom relevant clinical data were collected and analysed.
RESULTS:
Data from 908 RBCT episodes (2±1 units per transfused patient) were analysed. RBCT was considered appropriate in 21.4% (n=195), with significant differences according to RBCT indication (p<0.001), hospital level (p<0.001) and prescribing physician (p=0.002). Pre-transfusion haemoglobin level (Hb) negatively correlated with RBCT appropriateness (r=-0.616; p<0.01). Only 72.4% of appropriate RBCT had a post-transfusion Hb assessment (n=516). Of these, 45% were considered to be over-transfused (n=232), with significant differences according to RBCT indication (p=0.012) and prescribing physician (p=0.047). Overall, 584/1,433 (41%) of evaluable RBC units were unnecessarily transfused.
DISCUSSION:
The appropriateness of RBCT in ED is similar to other hospital departments, but the rate of over-transfusion was high. These data support the need for a reassessment after transfusion of each RBC unit before further units are prescribed. In view of these results, we recommend that physicians should be made more aware of the need to prescribe RBCT appropriately in order to reduce over-transfusionThis project has received funding from the Spanish Ministry of Health, Social Policy and Equality through the
