Molecular detection of Anaplasma platys infection in free-roaming dogs and ticks from Kenya and Ivory Coast.

Background: Anaplasma platys is a bacterium parasitic in the canine platelets, representing the causative agent of canine cyclic thrombocytopenia, with a worldwide distribution, mainly in tropical countries. The agent has zoonotic potential, being reported in several human clinical cases. The suspected vector is the tick Rhipicephalus sanguineus (sensu lato), widely distributed in animals and humans in the tropical regions of South America, Africa, Asia and Australia, but also in southern Europe.

Prognosis research and risk of bias.

The interest in prognosis research has been steadily growing during the past few decades because of its impact on clinical decision making. However, since the methodology of prognosis research is still incompletely defined, the quality of published prognosis studies is largely unsatisfactory. Seven major domain for risk of bias in prognosis research have been identified, including study participation, attrition, selection of candidate predictors, outcome definition, confounding factors, analysis, and interpretation of results.

Mouse mesenchymal stem cells inhibit high endothelial cell activation and lymphocyte homing to lymph nodes by releasing TIMP-1.

Mesenchymal stem cells (MSC) represent a promising therapeutic approach in many diseases in view of their potent immunomodulatory properties, which are only partially understood. Here, we show that the endothelium is a specific and key target of MSC during immunity and inflammation. In mice, MSC inhibit activation and proliferation of endothelial cells in remote inflamed lymph nodes (LNs), affect elongation and arborization of high endothelial venules (HEVs) and inhibit T-cell homing.

An Amulet to Say "Big is Not Enough".

We report the case of a man affected by non-valvular atrial fibrillation in whom a severely enlarged left atrial appendage with a narrow neck was successfully closed with a 34 mm Amplatzer Amulet device (St. Jude Medical). In the presence of a huge appendage with a narrow neck, as in this case, the Amulet should be considered an available option to ensure the feasibility of percutaneous closure.

Description of the male, redescription of the female and 16S rDNA sequence of Ixodes aulacodi (Ixodidae).

Ixodes (Afrixodes) aulacodiArthur, 1956 is a poorly known species that has been recorded predominantly in the wet countries of western and central Africa, mainly associated to the greater cane rat Thryonomys swinderianus (Temmink). We herein redescribe the female, describe the male (ascribed to the species from specimens found in copula) and provide the 16S rDNA sequence. We also provide complete illustrations of the adults based on specimens found on greater cane rats in Ivory Coast.

Mesenchymal Stromal Cell-Derived PTX3 Promotes Wound Healing via Fibrin Remodeling.

Although mesenchymal stromal cells (MSCs) can promote wound healing in different clinical settings, the underlying mechanism of MSC-mediated tissue repair has yet to be determined. Because a nonredundant role of pentraxin 3 (PTX3) in tissue repair and remodeling has been recently described, here we sought to determine whether MSC-derived PTX3 might play a role in wound healing. Using a murine model of skin repair, we found that Ptx3-deficient (Ptx3(-/-)) MSCs delayed wound closure and reduced granulation tissue formation compared with wt MSCs.

Cytauxzoon Infections in Wild Felids from Carpathian-Danubian-Pontic Space: Further Evidence for a Different Cytauxzoon Species in European Felids.

Parasitic protists of the genus Cytauxzoon are detected in a wide range of wild and domestic felids. Bobcats are a confirmed reservoir of Cytauxzoon felis in North America while domestic cats are susceptible hosts suffering from severe or fatal illness. Cytauxzoon infections are mainly reported from American felids and, recently, several sub-clinical and clinical findings were reported from European, Asian, and African felids.

Antibiotic resistance evaluation and clinical analysis of acute appendicitis; report of 1431 consecutive worldwide patients: A cohort study.

Background: Acute appendicitis (AA) is one of the most common diseases affecting especially young but also older people. A systematic evaluation of bacteriology of AA has been frequently conducted in children but is not well known and discussed in adult population.

Study Design: The study has been obtained from two multicenter prospective observational studies (CIAO and CIAOW studies).

Pancreaticojejunostomy Versus Pancreaticogastrostomy After Pancreaticoduodenectomy: An Up-to-date Meta-Analysis.

Background: The reconstruction of the pancreas after pancreaticoduodenectomy (PD) is a crucial factor in preventing postoperative complications as pancreatic anastomosis failure is associated with a high morbidity rate and contributes to prolonged hospitalization and mortality. Several techniques have been described for the reconstruction of pancreatic digestive continuity in the attempt to minimize the risk of a pancreatic fistula. The aim of this study was to compare the results of pancreaticogastrostomy and pancreaticojejunostomy after PD.

Human Mesenchymal Stem Cells Protect Dorsal Root Ganglia from the Neurotoxic Effect of Cisplatin.

Background/aim: Peripheral neurotoxicity is a dose-limiting factor of many chemotherapeutic agents, including cisplatin. Mesenchymal stem cells are promising for the treatment of several neurological disorders, and our aim was to verify the neuroprotective potential of human mesenchymal stem cells (hMSCs) on dorsal root ganglia (DRG) exposed to cisplatin.

Materials And Methods: DRG were exposed to different cisplatin concentrations and then co-cultured with hMSCs or with hMSC-conditioned medium.

Altitudinal and seasonal differences of tick communities in dogs from pastoralist tribes of Northern Kenya.

Studies regarding the distribution and ecology of ticks in dogs from Eastern Africa are scarce. Our research was based on a long-term screening of ticks parasitising the domestic dogs living with indigenous people around Lake Turkana, Mt. Kulal and Mt.

Development and Validation of a Distal Embolization Risk Score During Primary Angioplasty in ST-Elevation Myocardial Infarction.

This study aims to develop and validate a new angiographic risk score to predict the risk of distal embolization (DE) during primary percutaneous coronary intervention (p-PCI) for ST-elevation myocardial infarction. Study included data from 1,200 patients who underwent p-PCI. The cohort was randomly split into a derivation cohort (n = 814) and a validation cohort (n = 386).

A tsetse and tabanid fly survey of African great apes habitats reveals the presence of a novel trypanosome lineage but the absence of Trypanosoma brucei.

Tsetse and tabanid flies transmit several Trypanosoma species, some of which are human and livestock pathogens of major medical and socioeconomic impact in Africa. Recent advances in molecular techniques and phylogenetic analyses have revealed a growing diversity of previously unidentified tsetse-transmitted trypanosomes potentially pathogenic to livestock and/or other domestic animals as well as wildlife, including African great apes. To map the distribution, prevalence and co-occurrence of known and novel trypanosome species, we analyzed tsetse and tabanid flies collected in the primary forested part of the Dzanga-Sangha Protected Areas, Central African Republic, which hosts a broad spectrum of wildlife including primates and is virtually devoid of domestic animals.

Evaluation of acute cardiovascular effects of immediate-release methylphenidate in children and adolescents with attention-deficit hyperactivity disorder.

Attention-deficit hyperactivity disorder is a frequent condition in children and often extends into adulthood. Use of immediate-release methylphenidate (MPH) has raised concerns about potential cardiovascular adverse effects within a few hours after administration. This study was carried out to investigate acute effects of MPH on electrocardiogram (ECG) in a pediatric population.

Robotic-assisted Kidney Transplantation: Our Experience and Literature Review.

Kidney transplantation is the preferred treatment for patients with end-stage renal disease. While open surgery remains the gold standard, minimally invasive surgery has recently been introduced for the recipient undergoing kidney transplantation. Our team has employed the robotic surgical system to perform renal transplantation in obese recipients to minimize the risk of surgical site infections, with good results in terms of complications and graft and patient survival.

Intracellular free radical production by peripheral blood T lymphocytes from patients with systemic sclerosis: role of NADPH oxidase and ERK1/2.

Introduction: Abnormal oxidative stress has been described in systemic sclerosis (SSc) and previous works from our laboratory demonstrated an increased generation of reactive oxygen species (ROS) by SSc fibroblasts and monocytes. This study investigated the ability of SSc T lymphocytes to produce ROS, the molecular pathway involved, and the biological effects of ROS on SSc phenotype.

Methods: Peripheral blood T lymphocytes were isolated from serum of healthy controls or SSc patients by negative selection with magnetic beads and activated either with PMA or with magnetic beads coated with anti-CD3 and anti-CD28 antibodies.

Granulocytic anaplasmosis is a common vector-borne disease of humans and animals with natural transmission cycle that involves tick vectors, among which Ixodes ricinus is the most important. The present paper reports the prevalence and geographical distribution of A. phagocytophilum in 10,438 questing Ixodes ricinus ticks collected at 113 locations from 40 counties of Romania.

Transstadial transmission of Borrelia turcica in Hyalomma aegyptium ticks.

Borrelia turcica comprises the third major group of arthropod-transmitted borreliae and is phylogenetically divergent from other Borrelia groups. The novel group of Borrelia was initially isolated from Hyalomma aegyptium ticks in Turkey and it was recently found in blood and multiple organs of tortoises exported from Jordan to Japan. However, the ecology of these spirochetes and their development in ticks or the vertebrate hosts were not investigated in detail; our aims were to isolate the pathogen and to evaluate the possibility of transstadial transmission of Borrelia turcica by H.

Combined Robot-assisted Kidney Transplantation and Sleeve Gastrectomy in a Morbidly Obese Recipient.

Background: Kidney transplantation confers a well-documented survival advantage for patients with end-stage renal disease (ESRD) over dialysis, regardless of body mass index (BMI). However, obese patients with ESRD have limited access to kidney transplantation. In most transplant centers, a patient with a BMI above 35 to 40 kg/m is either completely excluded from transplantation or is required to lose weight before being considered for transplantation.
