Background Cats can be carriers of infected arthropods and be infected with several vector-borne pathogens (VBP) but there is limited knowledge about their pathogenic role in cats. Results A cross-sectional controlled study investigated the clinical status and antibody ( Bartonella henselae , Rickettsia conorii , Ehrlichia canis , Anaplasma phagocytophilum , Babesia microti and Leishmania infantum ) and/or blood PCR ( Mycoplasma spp., Bartonella spp., Rickettsia spp., Ehrlichia/Anaplasma spp., piroplasmids, L. infantum , Hepatozoon felis ) prevalence in 197 cats. Outdoor cats lacking ectoparasiticide treatment or hosting ectoparasites (study group [SG], n = 134) and indoor cats treated against ectoparasites (control group [CG], n = 63) were enrolled. Clinical data and retroviral co-infections were compared between the two groups. Multivariable analysis tested associations between variables and VBP exposure. Lymphadenia, stomatitis, and various haematological abnormalities were statistically more frequent in SG. Antibodies against R. conorii , B. henselae , A. phagocytophylum , B. microti , E. canis and L. infantum were detected. Bartonella henselae , Bartonella clarridgeiae , Mycoplasma haemofelis , “ Candidatus Mycoplasma haemominutum” and “ Candidatus Mycoplasma turicensis” DNA were identified. Very high antibody (87.8%) and PCR (40.1%) positivity to at least one pathogen were detected and were significantly higher in SG. Co-infections were confirmed in about one-third of the cats and were more frequent in SG cats. Molecular and overall (antibody and PCR) positivity to Bartonella and antibody positivity to R. conorii were higher in SG. Multivariable analysis found significant associations of Bartonella spp. infection with Feline Immunodeficiency Virus (FIV) infection and increased globulins, and of Mycoplasma spp. infection with adult age, FIV infection, anaemia, and increased creatinine. Conclusions A very high prevalence of exposure to zoonotic VBP was found in cats, with Rickettsia and Bartonella infections being most prevalent. Some risk factors were documented namely for Mycoplasma spp. and Bartonella spp. The lifestyle of cats is clinically relevant and requires specific preventative measures to protect their health.

Dogs are the major reservoir of Leishmania infantum, the causative agent of canine visceral and cutaneous human leishmaniasis in the Mediterranean basin. Canine and human leishmaniosis are endemic in Italy, particularly in central and southern regions, including islands. Here we show a preliminary, clinical, serological and molecular study carried out in Pantelleria island during 2017. In this study, we clinically examined 136 dogs for the presence of symptoms compatible with leishmaniasis, determined the titer of anti‑Leishmania antibodies, and investigated Leishmania DNA by real time PCR in blood and/or lymph node of each dog. The prevalence of disease was equal to 27% with 95% CI [21%; 32%], lower than prevalence obtained in the other Sicily islands (Lampedusa, Lipari). We observed that enlarged lymph nodes was more positively associated with canine leishmaniasis (CanL)than other clinical signs. The results obtained showed that in an endemic area, such as Sicily, diagnosis of CanL needs to be carried out by including an immunological, molecular clinical approach.

Background Anti- Leishmania antibodies are increasingly investigated in cats for epidemiological studies or for the diagnosis of clinical feline leishmaniosis. The immunofluorescent antibody test (IFAT), the enzyme-linked immunosorbent assay (ELISA) and western blot (WB) are the serological tests more frequently used. The aim of the present study was to assess diagnostic performance of IFAT, ELISA and WB to detect anti- L. infantum antibodies in feline serum samples obtained from endemic ( n  = 76) and non-endemic ( n  = 64) areas and from cats affected by feline leishmaniosis ( n  = 21) by a Bayesian approach without a gold standard. Methods Cut-offs were set at 80 titre for IFAT and 40 ELISA units for ELISA. WB was considered positive in presence of at least a 18 KDa band. Statistical analysis was performed through a written routine with MATLAB software in the Bayesian framework. The latent data and observations from the joint posterior were simulated in the Bayesian approach by an iterative Markov Chain Monte Carlo technique using the Gibbs sampler for estimating sensitivity and specificity of the three tests. Results The median seroprevalence in the sample used for evaluating the performance of tests was estimated at 0.27 [credible interval (CI) = 0.20–0.34]. The median sensitivity of the three different methods was 0.97 (CI: 0.86–1.00), 0.75 (CI: 0.61–0.87) and 0.70 (CI: 0.56–0.83) for WB, IFAT and ELISA, respectively. Median specificity reached 0.99 (CI: 0.96–1.00) with WB, 0.97 (CI: 0.93–0.99) with IFAT and 0.98 (CI: 0.94–1.00) with ELISA. IFAT was more sensitive than ELISA (75 vs 70%) for the detection of subclinical infection while ELISA was better for diagnosing clinical leishmaniosis when compared with IFAT (98 vs 97%). Conclusions The overall performance of all serological techniques was good and the most accurate test for anti- Leishmania antibody detection in feline serum samples was WB.

This type of policy has been so identified with LaRouche that his enemies have often said that in a time of financial crisis, such as now, LaRouche would have a chance to come to power. In a desperate attempt to prevent this from happening, the Democratic Party and the Supreme Court have united forces to nullify the Voting Rights Act of 1965, in order to keep LaRouche from getting delegates to the August Democratic national convention; just as they did to Fannie Lou Hamer in 1964. As Martin Luther King believed, LaRouche believes in justice for all. The policy that he demands is not just for the United States, but for the world. LaRouche's Committee for the New Bretton Woods is calling for a world conference, with countries such as, Russia, China, India, the United States, and others, to work together, to form an alliance among sovereign nation states, based on the General Welfare Clause of the U.S. Constitution. LaRouche minces no words in saying that if this is not accomplished, humanity will quickly fall into a dark age. Although LaRouche identifies the crisis as financial, lie says it goes far beyond that. Just after the verdict in the shooting of Amadou Diallo, LaRouche called for the formation of a \"Commission to Investigate the New Violence.\" In contrast to most politicians, LaRouche claims that the solution is (not) to take the guns away, but to take back the educational system from the video stores and clowns who are turning our children into zombies. In an address to the founding meeting of the Commission in New York City on April 8, LaRouche said, \"We're taking the present generation of children, now between 3 and 16, approximately, and we're subjecting them with the aid of drugs, to become programmed killers on impulse, turning these children against their parents. Children killing parents... There are precedents for this in history, precedents in the ancient cult of Dionysius. It's come back.\"

If you ask most Americans whom they're going to vote for, they would admit that they don't want to vote for Bush or Gore, but that there's no alternative.

The Mesozoic era (252–66 million years ago), known as the domain of dinosaurs, witnessed a remarkable ecomorphological diversity of early mammals. The key mammalian characteristics originated during this period and were prerequisite for their evolutionary success after extinction of the non-avian dinosaurs 66 million years ago. Many ecomorphotypes familiar to modern mammal fauna evolved independently early in mammalian evolutionary history. Here we report a 125-million-year-old eutriconodontan mammal from Spain with extraordinary preservation of skin and pelage that extends the record of key mammalian integumentary features into the Mesozoic era. The new mammalian specimen exhibits such typical mammalian features as pelage, mane, pinna, and a variety of skin structures: keratinous dermal scutes, protospines composed of hair-like tubules, and compound follicles with primary and secondary hairs. The skin structures of this new Mesozoic mammal encompass the same combination of integumentary features as those evolved independently in other crown Mammalia, with similarly broad structural variations as in extant mammals. Soft tissues in the thorax and abdomen (alveolar lungs and liver) suggest the presence of a muscular diaphragm. The eutriconodont has molariform tooth replacement, ossified Meckel’s cartilage of the middle ear, and specialized xenarthrous articulations of posterior dorsal vertebrae, convergent with extant xenarthran mammals, which strengthened the vertebral column for locomotion. Description of a well-preserved 125-million-year-old fossil of a triconodont mammal from Spain, which extends the record of mammalian soft-tissue preservation back into the Mesozoic era. Soft tissue preserved in a Mesozoic fossil The triconodonts are a type of extinct early mammal, so named for their characteristic three-cusped molars. The extraordinarily well-preserved 125-million-year-old triconodont fossil reported here pushes back the earliest record of mammalian soft-tissue preservation by over 60 million years. Named Spinolestes xenarthrosus , the fossil from Las Hoyas, Spain, exhibits typical mammalian features including fur, an external ear, and skin structures including — on its back — tiny spines resembling those of hedgehogs and spiny mice. Under the skin there is evidence for a liver and alveolar lungs, suggesting the presence of a muscular diaphragm.

The Tapejaridae is a group of unusual toothless pterosaurs characterized by bizarre cranial crests. From a paleoecological point of view, frugivorous feeding habits have often been suggested for one of its included clades, the Tapejarinae. So far, the presence of these intriguing flying reptiles has been unambiguously documented from Early Cretaceous sites in China and Brazil, where pterosaur fossils are less rare and fragmentary than in similarly-aged European strata. Europejara olcadesorum gen. et sp. nov. is diagnosed by a unique combination of characters including an unusual caudally recurved dentary crest. It represents the oldest known member of Tapejaridae and the oldest known toothless pterosaur. The new taxon documents the earliest stage of the acquisition of this anatomical feature during the evolutionary history of the Pterodactyloidea. This innovation may have been linked to the development of new feeding strategies. The discovery of Europejara in the Barremian of the Iberian Peninsula reveals an earlier and broader global distribution of tapejarids, suggesting a Eurasian origin of this group. It adds to the poorly known pterosaur fauna of the Las Hoyas locality and contributes to a better understanding of the paleoecology of this Konservat-Lagerstätte. Finally, the significance of a probable contribution of tapejarine tapejarids to the early angiosperm dispersal is discussed.

In Europe, approximatively 100 000 to 500 000 tendon repairs are performed every year. These procedures are associated with a considerable rate of postoperative complications (from 6% to 11%). Autologous micro‐grafts (AAMG) and stromal vascular fraction (SVF) have been shown to improve tendon healing in 60% to 70% of treated rodents. The purpose of this study was to evaluate the effects of AAMG in a sheep model with tendinopathy. We used sheep models because, as a large animal, they are more comparable to humans. The hypothesis was that SVF injection would improve tendon healing compared with the control group, reducing inflammatory and matrix degrading, while increasing anti‐inflammatory expression and collagen synthesis in the early stage of tendon injury. Sixteen Apennine sheep aged 2 to 5 years underwent 500 UI type I collagenase injection into both common calcaneal tendons (CCT) to induce tendinopathy. After 15 days (T0), one CCT in every ovine underwent randomly to 2.5 mL of AAMG obtained by mechanical disruption and the contralateral CCTs received no treatment. Clinical, ecographic, and sonographic evaluations were performed after 4 weeks (T1) and 8 weeks (T2). Histological, immunohistochemical, real‐time polymerase chain reaction (RT‐PCR), and biomechanical evaluations were performed at T2. At T2, the treated group showed a final tendon diameter (9.1 ± 1.4 mm) and a hardness expression (62%) that were similar to the original healthy tendon (8.1 ± 1.1 mm; 100%), with a significant recovery compared with the control group (9.5 ± 1.7 mm; 39%). Moreover, histological analysis of the treated group revealed an improvement in the fiber orientation score, fiber edema score, infiltrative‐inflammatory process, and necrosis score (4.3 ± 3.3) compared with control group (8.8 ± 2.9). Immunohistochemically, the treated group showed high expression of collagen 1, Factor VIII and significantly low expression of collagen 3. These data were confirmed by RT‐PCR analysis. The study findings suggested that AAMGs obtained through mechanical disruption present a safe, efficient, and reliable technique, enhancing tendon healing. The group treated with stromal vascular fraction showed a final tendon diameter and a percentage hardness expression that were similar to the original healthy tendon.

Background Canine otitis externa is a painful condition which can be challenging to treat due to difficulties in the administration of otic medication. This can be due to lack of owner compliance in the application of ear drops or due to the resentment that some dogs demonstrate when attempts are made to administer topical medication into a sensitive ear canal. The aim of the study was to assess the efficacy of a topical LED-illuminated gel ( LIG ) in canine otitis externa in comparison to standard of care therapy. Dogs with spontaneous otitis externa were randomly allocated in three groups: groups QW received LIG once weekly; BW received LIG twice weekly; group C received enrofloxacin and silver sulfadiazine twice daily. LIG consists of a topical application of a gel containing chromophores that, when illuminated by a LED lamp, re-emit fluorescent light which can stimulate physiological responses, promoting healing and controlling bacteria. The evaluation protocol (T 0 to T 5 ) considered clinical assessment (OTIS-3-index-scoring-system; pruritus-severity-scale; pain-severity-score; aural temperature), cytological scoring system, quali-quantitative bacteriologic assessment. Results All groups (QW, n  = 21; BW, n  = 23; C, n  = 20) showed improvement during the study (QW: P  < 0.02 for cytological and pain scores, P  < 0.003 for bacteriologic assessment, P  < 10 − 4 for pruritus, total OTIS-3 and temperature assessments; BW: P  < 10 − 4 for all clinical, cytological and bacteriologic assessments; C: P  < 0.02 for all clinical and cytological assessments, P  < 10 − 4 for bacteriologic assessment). The highest clinical score reduction occurred in Group BW ( P  < 0.014 in T 3 ; P  < 0.001 in T 4 and P  < 10 − 4 in T 5 ). BW reached the clinically relevant effect level at T 3 (− 3.26 ± 1.21 levels), QW reached it at T 4 (− 3.24 ± 0.99), C did not reach it. No differences between groups were seen in the reduction of CFU/mL (T 0 -T 5 ). Conclusions All treatment groups showed a positive clinical effect. LIG administered twice-a-week was the most favourable protocol of the study. LIG may be considered beneficial in the management of canine otitis externa; it seems to be effective in controlling the clinical condition, including the signs of inflammation and local pain, the bacterial growth, and it may help increasing treatment compliance.

BackgroundQuick Sequential Organ Failure Assessment (qSOFA) score is a bedside prognostic tool for patients with suspected infection outside the intensive care unit (ICU), which is particularly useful when laboratory analyses are not readily available. However, its performance in potentially septic patients with community-acquired pneumonia (CAP) needs to be examined further, especially in relation to early outcomes affecting acute management.ObjectiveFirst, to compare the performance of qSOFA and CURB-65 in the prediction of mortality in the emergency department in patients presenting with CAP. Second, to study patients who required critical care support (CCS) and ICU admission.MethodsBetween January and December 2017, a 1-year retrospective observational study was carried out of adult (≥18 years old) patients presenting to the emergency department (ED) of our hospital (Rome, Italy) with CAP. The accuracy of qSOFA, qSOFA-65 and CURB-65 was compared in predicting mortality in the ED, CCS requirement and ICU admission. The concordance among scores ≥2 was then assessed for 30-day estimated mortality prediction.Results505 patients with CAP were enrolled. Median age was 71.0 years and mortality rate in the ED was 4.7%. The areas under the curve (AUCs) of qSOFA-65, CURB-65 and qSOFA in predicting mortality rate in the ED were 0.949 (95% CI 0.873 to 0.976), 0.923 (0.867 to 0.980) and 0.909 (0.847 to 0.971), respectively. The likelihood ratio of a patient having a qSOFA score ≥2 points was higher than for qSOFA-65 or CURB-65 (11 vs 7 vs 6.7). The AUCs of qSOFA, qSOFA-65 and CURB-65 in predicting CCS requirement were 0.862 (95% CI 0.802 to 0.923), 0.824 (0.758 to 0.890) and 0.821 (0.754 to 0.888), respectively. The AUCs of qSOFA-65, qSOFA and CURB-65 in predicting ICU admission were 0.593 (95% CI 0.511 to 0.676), 0.585 (0.503 to 0.667) and 0.570 (0.488 to 0.653), respectively. The concordance between qSOFA-65 and CURB-65 in 30-day estimated mortality prediction was 93%.ConclusionqSOFA is a valuable score for predicting mortality in the ED and for the prompt identification of patients with CAP requiring CCS. qSOFA-65 may further improve the performance of this useful score, showing also good concordance with CURB-65 in 30-day estimated mortality prediction.
