Abstract
This paper introduces CYCLOPS, an acquisition system developed to capture images and inertial measurement data of moving cyclists from a vehicle. The development of CYCLOPS addresses the need to acquire useful data for training machine learning models capable of predicting the motion intentions of cyclists on urban roads. Considering its application, it is a completely original development. The system consists of two devices. The first device is installed on the bicycle and is based on an electronic acquisition board comprising an inertial measurement unit (IMU), a microcontroller, and a transceiver for sending the cyclist's acceleration and orientation data to a vehicle. The second device is installed on the vehicle and uses the same board architecture to acquire the vehicle's accelerations and orientations, along with an RGB monocular camera. The data is stored in real-time in a laptop's drive for subsequent analysis and manipulation. The hardware architecture is presented in detail, including the designs to install the devices, for IMUs configuration, and software installation on the laptop. All design and software files required to develop the proposed system are available for download at: doi.org/10.17632/3yx5y8b7tm.1, licensed under the Open-source license CC BY 4.0.

Abstract
BACKGROUND Suboptimal response to ursodeoxycholic acid occurs in 40% of primary biliary cholangitis (PBC) patients, affecting survival. Achieving a deep response (normalisation of alkaline phosphatase [ALP] and bilirubin ≤0.6 upper limit of normal) improves survival. Yet, the long-term effectiveness of second-line treatments remains uncertain. AIMS To evaluate the long-term effectiveness of obeticholic acid (OCA) ± fibrates. Focusing on biochemical response (ALP ≤1.67 times the upper limit of normal, with a decrease of at least 15% from baseline and normal bilirubin levels), normalisation of ALP, deep response and biochemical remission (deep response plus aminotransferase normalisation). METHODS We conducted a longitudinal, observational, multicentre study involving ursodeoxyccholic acid non-responsive PBC patients (Paris-II criteria) from Spain and Portugal who received OCA ± fibrates. RESULTS Of 255 patients, median follow-up was 35.1 months (IQR: 20.2-53). The biochemical response in the whole cohort was 47.2%, 61.4% and 68.6% at 12, 24 and 36 months. GLOBE-PBC and 5-year UK-PBC scores improved (p < 0.001). Triple therapy (ursodeoxycholic acid plus OCA plus fibrates) had significantly higher response rates than dual therapy (p = 0.001), including ALP normalisation, deep response and biochemical remission (p < 0.001). In multivariate analysis, triple therapy remained independently associated with biochemical response (p = 0.024), alkaline phosphatase normalisation, deep response and biochemical remission (p < 0.001). Adverse effects occurred in 41.2% of cases, leading to 18.8% discontinuing OCA. Out of 55 patients with cirrhosis, 12 developed decompensation. All with baseline portal hypertension. CONCLUSION Triple therapy was superior in achieving therapeutic goals in UDCA-nonresponsive PBC. Decompensation was linked to pre-existing portal hypertension.

Abstract
Serological controls for diseases of viral origin in animal production systems and the identification of factors associated with infections are decisive elements to establish prevention and control measures. The aim of this study was to establish the serological status for Bovine Viral Diarrhea (BVD) and Enzootic Bovine Leukemia (EBL) viruses in Blanco Orejinegro (BON) cattle from Colombia, and to identify the factors associated with seropositivity. A cross-sectional study was conducted with a total of 498 animals of all age groups and physiological states of the BON breed were selected, belonging to 14 herds located in 6 states of Colombia, in which a survey with 27 questions was conducted. By means of the chi-square test, possible factors associated with seropositivity against the 2 viruses were identified. A sample of 4 ml of blood was taken from each animal to extract plasma and make indirect Elisa tests to detect antibodies against both pathogens. General seropositivity of 27,1% was obtained for EBL, finding as factors associated with seropositivity the inadequate disposition of placental tissues after delivery of the cows and the non-performance of serological tests on new animals entering the herd. For BVD, seropositivity obtained was 50,6%, and the factors associated with seropositivity identified were having had a history of the disease in the herd, and using semen from bulls that are not known to be free for the infection. We suggest establishing control measures considering the factors associated with each viral infection to limit their expansion in the BON cattle production systems of Colombia.

Efficacy and Safety of Therapy With Simeprevir and Sofosbuvir in Liver Transplant Recipients Infected by Hepatitis C Virus Genotype 4: Cohort Spanish Society of Liver Transplantation Cohort.

Abstract
BACKGROUND Patients with hepatitis C virus (HCV) genotype 4 infection are poorly represented in clinical trials of 2nd-generation direct-acting antivirals (DAAs), and more data are needed to help guide treatment decisions. We still have even fewer data concerning liver transplant patients. Simeprevir (SIM) and sofosbuvir (SOF) combination is useful to treat this genotype. The aim of this study was to know the efficacy and safety of the combination SIM + SOF ± ribavirin (RBV) in a group of liver transplant patients with HCV genotype 4 infection in Spain in real life. METHODS This was a multicenter retrospective study, including 28 HCV genotype 4 patients from 11 liver transplant centers who were treated with SIM + SOF ± RBV. We included in the analysis demographic, clinical, and virologic data and details of serious adverse events (SAEs), including mortality rate 6 months after treatment. RESULTS All patients were male, mean age 52 ± 9.43 years, and 50% were IL28B CT and 37.5% TT; 46.42% of them were pretreated and 76.9 were null responders. Fibrosis stage 4 was found in 38.7% of patients; in 67.8% of those cases the diagnosis of fibrosis was made with the use of Fibroscan, in 21.4% by liver biopsy. The average Fibroscan was 13.86 KPa. The average Model for End-Stage Liver Disease (MELD) score of cirrhotic patients was 10.9 and the Child-Pugh score was A in 70%, B in 20%, and C in 10%. We included RBV in 75% of patients, and treatment duration was 12 weeks in all patients. The sustained virologic response at week 12 (SVR12) was 95.23%. There were no discontinuations due to SAEs, but the mortality rate at 6 months after treatment was 7.14%. All deceased patients were cirrhotic, Child C, and with an average MELD score of 20. CONCLUSIONS The combination SIM + SOF ± RBV to treat HCV genotype 4 in liver transplant patients is an option with high rates of SVR12 and very safe, similarly to genotype 1. There was no treatment-related mortality, but when it is administered in advanced stages of fibrosis it may not be enough to prevent mortality associated with cirrhotic hepatitis C recurrence after transplantation.
