Infectious blood meal experiments have been frequently performed with different virus-vector combinations to assess the transmission potential of arthropod-borne (arbo)viruses. A wide variety of host blood sources have been used to deliver arboviruses to their arthropod vectors in laboratory studies. The type of blood used during vector competence experiments does not always reflect the blood from the viremic vertebrate hosts in the field, but little is known about the effect of blood source on the experimental outcome of vector competence studies. Here we investigated the effect of avian versus human blood on the infection and transmission rates of the zoonotic Usutu virus (USUV) in its primary mosquito vector Culex pipiens.

Cx. pipiens biotypes (pipiens and molestus) were orally infected with USUV through infectious blood meals containing either chicken or human whole blood. The USUV infection and transmission rates were determined by checking mosquito bodies and saliva for USUV presence after 14days ofpe pipiens due to very low virus titers in the saliva.

Infection of mosquitoes with human blood led to higher USUV infection rates as compared to chicken blood. However, the blood source had no effect on the vector competence for USUV. Interestingly, biotype molestus is less likely to transmit USUV compared to biotype pipiens due to very low virus titers in the saliva.

The European Reference Network on Rare Multisystemic Vascular Diseases (VASCERN) was launched in 2017 and involves, to date, 35 highly specialised multidisciplinary expert centres (from the 30 full Healthcare Provider members) coming from 11 countries and more than 70 patient organizations from 16 countries. The eHealth Working Group (WG) of VASCERN was set up to develop practical, patient-centred solutions and strategies for effective use of eHealth tools to answer the needs of patients with multisystemic vascular rare diseases.

Following the identified patients' needs and following the guiding principles of collaboration and patient-centredness, the eHealth WG was created with the following aims to develop a mobile app to help patients find expert centres and patient organizations, and to develop resources (Pills of Knowledge, PoK) for training and education via digital platforms (eLearning). The mobile app includes, to date, functionalities that allow users to find expert centres and patient organizati strategic assets in achieving the ultimate goal of ensuring equity of access to prevention programs, timely and accurate diagnosis and specialized care for patients with rare diseases throughout Europe.

Overall, the work carried out by the eHealth WG of VASCERN can be seen as a pilot experience that may serve as a basis to for collaborative development of patient-centred eHealth tools that answer the needs of patients with various rare diseases, not limited to rare multisystemic vascular diseases. By expanding the multidisciplinary approach here described, clinical and research networks can take advantage of eHealth services and use them as strategic assets in achieving the ultimate goal of ensuring equity of access to prevention programs, timely and accurate diagnosis and specialized care for patients with rare diseases throughout Europe.

This study presents patient-reported outcome measures after combined matrix-associated autologous chondrocyte implantation and autologous bone grafting in high-stage osteochondral lesions of the talus in adolescents.

A total of 12 adolescent patients (13 ankles) received matrix-associated autologous chondrocyte implantation and autologous bone grafting for a solitary osteochondral lesion of the talus at a single centre. The Foot and Ankle Outcome Score and Foot and Ankle Ability Measure were defined as outcome measures (median follow-up 80 months [range 22-107 months]). Pre- and postoperative ankle radiographs were evaluated according to the van Dijk ankle osteoarthritis scale.

The study population consisted of four male and nine female cases (mean age at the time of surgery, 17.7 ± 2.1 years). Eight lesions were classified as traumatic and five as idiopathic. Twelve lesions were located medial vs one lateral in the coronal plane and allcentral in the sagittal plane. The median lesion size and depth wer bone grafting for high-stage osteochondral lesions of the talus in adolescents show heterogeneous results. Long-term limitations mainly affect sports and recreational activities. Selleckchem MPI-0479605 Osteochondral lesions of the talus are associated with osteoarthritis, even preoperatively. However, we did not find significant osteoarthritis progression after matrix-associated autologous chondrocyte implantation and autologous bone grafting in the long term.

In sub-Saharan Africa the treatment gap for mental disorders is high. In 2009, 98.0% of people with mental illness in Sierra Leone were not receiving treatment, partly due to the absence of public psychiatric facilities outside the capital. In response, the Ministry of Health and Sanitation rolled out nurse-led mental health units (MHU) to every district. This study aims to retrospectively evaluate the uptake of these services by examining the pathways to care, diagnosis, management, and treatment gap, to provide insight into the functioning of these units and the potential burden of mental health disorders in Sierra Leone.

We evaluated the roll out of MHU using summary data from all units between 1 st January 2015 and 1 st January 2017, to establish the burden of diagnoses among service users, pathways to care, treatments provided, and treatment gaps. Negative binomial regressions examine bivariate relationships between diagnoses, treatments, and medication inaccessibility with demographics (age and sex), location (Freetown vs the rest and Ebola endemic regions vs the rest) and year.

We collected data from 15 MHU covering 13 districts in 24months. There were 2401 referrals. The largest age category was 25-34 (23.4%). The prominent diagnoses were epilepsy (43.5%, associated with children) and psychosis (17.5%, associated with males). Reported depression (8.6%) and suicide attempts (33 patients) were low. Ebola endemic regions reported higher rates of grief, trauma, and medically unexplained symptoms. In 24.7% of cases where medication was required, it was not accessible.

Nurse-led MHU can have a modest effect on the treatment gap in resource constrained environments such as Sierra Leone, particularly in epilepsy and psychosis.
