Thermographic ocular temperature correlated with rectal temperature in cats.

Body temperature reflects the animal health and/or disease conditions. During clinical examination, temperature measurement is a basic step in veterinary medicine. The conventional method used is the rectal thermometry, particularly stressful in some subjects, especially for cats. A less stressful alternative method, such as infrared thermal imaging camera, is used in various fields of medicine for diagnosis, prognosis and correct therapeutic approaches. To evaluate the usefulness of infrared thermal imaging for the assessment of ocular temperature, twenty cats of different breeds (European, Siamese and Persian, 4-6 years old, mean body weight 4.3 ± 0.30 Kg) were enrolled in the study. In order to evaluate the applicability of the ocular temperature assessment through thermal imaging as a tool for measuring the animal's body temperature, the obtained values were compared with the rectal temperature values recorded in each cat by means of a digital thermo-camera. There were no differences between left and right eye; and a difference of about 1.19 °C between the ocular and rectal temperature value was recorded (p < 0.0001). Rectal and ocular temperatures were positively correlated (p < 0.0001; r = 0.93). In conclusion, we show that ocular temperature is an alternative method for body temperature measurement that can be used in clinical evaluation of cats, especially in cases where rectal temperature recording is not possible.

Major trauma critical pathway: preliminary results from the monitoring system in the regional network and in a hub center in Rome metropolitan area.

OBJECTIVE: The aim of this study is to collect the two years' data regarding the Integrated Trauma Management System (SIAT) by capturing the activity of its three Hubs in the Italian Lazio Region and test the performance of one of the Hubs' (Fondazione Policlinico Universitario A. Gemelli - IRCCS, FPG -IRCCS) Major Trauma Clinical Pathway's (MTCP) monitoring system, introducing the preliminary results through volume, process and outcome indicators. MATERIALS AND METHODS: A retrospective analysis on SIAT was conducted on years 2016 to 2018, by collecting outcome and timeliness indicators through the Lazio Informative System whereas the MTCP was monitored through set of indicators from the FPG - IRCCS Informative System belonging to randomly selected clinical records of the established period. RESULTS: Hubs managed 11.3% of the 998,240 patients admitted in SIAT. All patients eligible for MTCP were "Flagged", and 83% underwent a CT within 2 hours; intra-hospital mortality was 13% whereas readmission rates 16.9%. CONCLUSIONS: SIAT converges the most severe patients to its Hubs. The MTCP monitoring system was able to measure a total of 9 out of 13 indicators from the original panel. This research may serve as a departing point to conduct a pre-post analysis on the performance of the MTCP.

CD3+ graft cell count influence on chronic GVHD in haploidentical allogeneic transplantation using post-transplant cyclophosphamide.

The effects of graft or donor characteristics in haploidentical hematopoietic cell transplantation (HCT) using post-transplant cyclophosphamide (PT-Cy) are largely unknown. In this multicenter retrospective study we analyzed the correlations between graft cell composition (CD34+, CD3+) and donor features on transplant outcomes in 234 patients who underwent HCT between 2010 and 2016. On multivariate analysis, the use of peripheral blood stem cells (PBSC) was associated with an increased incidence of grade 2-4 acute GVHD [HR 1.94, 95% confidence Interval (CI) = 1.01-3.98, p = 0.05]. An elevated CD3+ graft content was associated with an increased incidence of all-grade chronic GVHD [HR 1.36 (95% CI = 1.06-1.74), p = 0.01]. This effect was confirmed only for the PBSC graft group. A higher CD34+ graft content had a protective role on non-relapse mortality [HR 0.78 (95% CI = 0.62-0.96), p = 0.02] but this was confirmed only for the bone marrow (BM)-derived graft cohort. Donor characteristics did not influence any outcomes. GVHD prophylaxis should be modulated accordingly to CD3+ graft content, especially when a PBSC graft is used. These results need further validation in prospective trials.

Allogeneic stem cell transplantation and subsequent treatments as a comprehensive strategy for long-term survival of multiple myeloma patients.

We evaluated 71 patients treated with allogeneic hematopoietic cell transplantation (allo-HCT) for multiple myeloma (MM). Forty-three patients (61%) received allo-HCT after the first line of therapy. Fifty-eight patients (82%) had chemosensitive disease at the time of allo-HCT. A HLA-matched related or unrelated donor was available for 68 patients (96%). Non-myeloablative or reduced-intensity conditioning regimen and peripheral blood hematopoietic cells as a graft source were used in most patients. The cumulative incidence of grade II-IV acute GVHD at day +100 and chronic GVHD at 5 years was 13% (95% CI 7-23%) and 35% (95% CI 24-46), respectively. Non-relapse mortality and relapse/progression incidence at 5 years were 12% (95% CI 5-23) and 65% (95% CI 49-76), respectively. With a median follow-up in survivors of 100 months (range 16-186), the 5-year PFS and OS were 39% (95% CI 27-52) and 60% (95% CI 55-77), respectively. On multivariate analysis: age >55 years was associated with both a reduced PFS (RR 2.11, 95% CI 1.15-3.87) and OS (RR 5.53, 95% CI 2.22-13.76); chemorefractory disease at allo-HCT was associated with both reduced PFS (RR 3.09, 95% CI 1.37-7.00) and OS (RR 3.19, 95% CI 1.23-8.22). At relapse, 24 patients (56%) received bortezomib, 28 (65%) lenalidomide, 11 (26%) pomalidomide, 16 (37%) donor lymphocytes infusion as part of salvage therapy after allo-HCT relapse. Median PFS from time of salvage treatment was 7 months (range 0-113 months) for bortezomib-based therapy, 14 months (range 0-79 months) for lenalidomide and 10 months (range 1-28) for pomalidomide. Allo-HCT is a feasible and effective strategy in selected patients with MM and could be an effective platform for subsequent therapies.

Dog erythrocyte antigens (DEA) 1, 4, 7 and suspected naturally occurring anti-DEA 7 antibodies in Italian Corso dogs.

We sought to determine the prevalence of dog erythrocyte antigen (DEA) 1, 4 and 7 and naturally occurring anti-DEA7 antibodies in Italian Corso dogs. In addition, we correlated DEAs with different epidemiologic variables, compared the prevalence of DEAs against other canine populations and assessed the risk of sensitisation and transfusion reactions (TRs) following unmatched transfusion. Blood samples from 100 Corso dogs were evaluated for DEA 1, 4, 7 and naturally occurring anti-DEA 7 antibodies. Seventy-one percent of samples were DEA 1-negative, 100% tested DEA 4-positive, and 95% tested DEA 7-negative. Suspected anti-DEA7 antibodies were found in 32% dogs. The DEA 1 and 7-negative phenotypes were significantly more common than in most canine populations. When a previously tested Italian canine population was considered as blood donors for Corso dogs, the risk of DEA 1 sensitisation using DEA 1 untyped blood was 29%, and of acute haemolytic TRs after a second untyped DEA 1-incompatible transfusion was 8%. The potential for delayed TRs between DEA 7-negative Corso dogs with suspected naturally occurring anti-DEA 7 antibodies receiving untyped DEA 7-positive blood was 11%. Conversely, when Corso dogs were blood donors for the same population, the risk of DEA 1 sensitisation was 17% and the risk of an acute haemolytic TR after a second DEA 1-incompatible blood transfusion was 3%. Corso dogs can be suitable blood donors. Additional studies are needed to clarify whether the high prevalence of naturally occurring anti-DEA 7 antibodies in this breed could increase their risk of delayed TRs when they are blood recipients.

Detection of 'Candidatus Neoehrlichia mikurensis' and other Anaplasmataceae and Rickettsiaceae in Canidae in Switzerland and Mediterranean countries.

INTRODUCTION: 'Candidatus Neoehrlichia mikurensis' is an emerging tick-borne zoonotic agent that primarily affects immunocompromised human patients. Dogs and foxes are frequently exposed to ticks, and both species are in close proximity to humans. This is the first study to systematically investigate the occurrence of 'Candidatus Neoehrlichia mikurensis' in Canidae in Europa. We analyzed 1'739 blood samples from dogs in Switzerland, Italy, Spain and Portugal and 162 blood samples from free-ranging red foxes (Vulpes vulpes) in Switzerland. All samples were tested using a previously described multiplex real-time PCR for the Anaplasmataceae family, the 'Candidatus Neoehrlichia' genus and the 'Candidatus Neoehrlichia mikurensis' species. All Anaplasmataceae positive samples were subsequently tested using specific real-time PCRs for Anaplasma phagocytophilum, Anaplasma platys, Ehrlichia canis and Rickettsia helvetica. Among the tested animals, one dog from Zurich tested positive for 'Candidatus Neoehrlichia mikurensis'. The 12-year old West Highland white terrier had been splenectomized 3 months prior to the blood collection and presented with polyuria/polydipsia. Fanconi syndrome was diagnosed based on glucosuria with normoglycemia and hyperaminoaciduria. A. platys and E. canis were detected in 14/249 dogs from Sicily and Portugal; two of the dogs were coinfected with both agents. Four Swiss foxes tested positive for A. phagocytophilium. R. helvetica was detected for the first time in a red fox. In conclusion, 'Candidatus Neoehrlichia mikurensis' infection should be considered in sick dogs, particularly when immunocompromised. The pathogen seems not to be widespread in Canidae in the investigated countries. Conversely, other Anaplasmataceae were more readily detected in dogs and foxes.

INTRODUCTION: 'Candidatus Neoehrlichia mikurensis' est un agent de zoonose transmis par les tiques qui gagne en importance et concerne principalement les patients immunosupprimés. Les chiens comme les renards sont souvent concernés par des morsures de tiques et vivent en contact étroit avec les êtres humains. Dans le présent travail, nous étudions pour la première fois systématiquement la présence de 'Candidatus Neoehrlichia mikurensis' chez les canidés en Europe. Les échantillons sanguins analysés provenaient de 1'739 chiens de Suisse, d'Italie, d'Espagne et du Portugal ainsi que de 162 renards (Vulpes vulpes) de Suisse. Tous les échantillons ont été examinés avec un test de PCR multiplex en temps réel déjà publié quant à la présence d'agents de la famille des Anaplasmataceae, du genre 'Candidatus Neoehrlichia' et de l'espèce 'Candidatus Neoehrlichia mikurensis'. Les échantillons positifs aux Anaplasmataceae ont ensuite été testés avec un test PCR en temps réel spécifique quant à Anaplasma phagocytophilum, Anaplasma platys, Ehrlichia canis und Rickettsia helvetica. Parmi les échantillons examinés se trouvait celui d'un chien de Zürich qui était infecté par 'Candidatus Neoehrlichia mikurensis'. Ce West Highland White Terrier de 12 ans avait été présenté pour polyurie/polydipsie; il avait été splénectomisé trois mois avant la prise de l'échantillon. Au vu d'une glycosurie et d'une hyperaminoacidurie accompagnées d'une glycémie normale, on a posé le diagnostic de syndrome de Fanconi. A. platys et E. canis ont été mis en évidence chez 14/249 chiens provenant de Sicile et du Portugal; deux chiens étaient infectés par les deux agents pathogènes. Quatre renards suisses étaient positifs à A. phagocytophilium et R. helvetica a été trouvé pour la première fois chez un renard. En résumé, on peut dire qu'une infection à 'Candidatus Neoehrlichia mikurensis' chez un chien malade doit être prise en considération comme diagnostic différentiel, particulièrement chez les anomaux immunosupprimés. Toutefois cet agent n'est pas très répandu chez les canidés des pays examinés, contrairement aux autres Anaplasmataceae spp. qui ont été trouvées plus souvent chez les chiens et les renards.

New insights into the infection of the American cockroach Periplaneta americana nymphs with Metarhizium anisopliae s.l. (Ascomycota: Hypocreales).

AIMS: To study the marked resistance of Periplaneta americana to entomopathogenic Metarhizium anisopliae. METHODS AND RESULTS: The low susceptibility of 4th instar nymphs applied topically with conidia seemed to be related to an active removal of conidia by the cockroach and to a disabled or retarded germination and subsequent development of conidia on the cuticle (up to 80% germination in the next 7 days after application). Inhibitions or delays of germination were related to the composition of the epicuticular fatty acids (30·1% w/w oleic, 28·3% w/w linoleic, 24·5% w/w palmitic and 11·7% w/w stearic acid) reported here. Propagules invading the nymphs through the cuticle took at least 3 days to reach the haemocoel, and no propagules were found after day 8 post-treatment. Strain IP 46 infected >50% of nymphs treated with doses ≥2 × 104  hyphal bodies (HB) nymph-1 and reduced the survival of nymphs ≤50%. Most nymphs (>70%) survived after injection of 6 × 103 and 2 × 103  HB nymph-1 . CONCLUSIONS: Findings emphasize a distinct resistance of nymphs of the American cockroach to infections by M. anisopliae. SIGNIFICANCE AND IMPACT OF THE STUDY: Our findings provide support for the development of biological control of this synanthropic cockroach pest.

Clinical and microbiological outcome in septic patients with extremely low 25-hydroxyvitamin D levels at initiation of critical care.

A relationship between vitamin D status and mortality in patients in intensive care units (ICU) has been documented. The present study aims to describe the clinical profile and sepsis-related outcome of critically ill septic patients with extremely low (<7 ng/mL) vitamin D levels at ICU admission. We conducted an observational study in the ICU of a teaching hospital including all patients admitted with severe sepsis/septic shock and undergoing 25-hydroxyvitamin D (25(OH)D) testing within the first 24 hours from admission. We studied 107 patients over 12 months. At ICU admission vitamin D deficiency (≤20 ng/mL) was observed in 93.5% of the patients: 57 (53.3%) showed levels <7 ng/mL. As primary outcome, sepsis-related mortality rate was higher in patients with vitamin D levels <7 ng/mL (50.9% versus 26%). Multivariate regression analysis showed that vitamin D concentration <7 ng/mL on ICU admission (p 0.01) and higher mean SAPS II (p <0.01) score were independent predictors of sepsis-related mortality. Patients with very low vitamin D levels suffered higher rate of microbiologically confirmed infections but a lower percentage of microbiological eradication with respect to patients whose values were >7 ng/mL (80.7% versus 58%, p 0.02; 35.3% versus 68%; p 0.03, respectively). Post hoc analysis showed that, in the extremely low vitamin D group, the 52 patients with pneumonia showed a longer duration of mechanical ventilation (9 days (3.75-12.5 days) versus 4 days (2-9 days), p 0.04) and the 66 with septic shock needed vasopressor support for a longer period of time (7 days (4-10 days) versus 4 days (2-7.25 days), p 0.02). Our results suggest that in critical septic patients extremely low vitamin D levels on admission may be a major determinant of clinical outcome. Benefits of vitamin D replacement therapy in this population should be elucidated.

Cross-sectional survey on Tritrichomonas foetus infection in Italian cats.

The feline genotype of Tritrichomonas foetus is a widespread cause of large-bowel diarrhoea in cats. The aim of this study was to determine the prevalence of the T. foetus infection in cat populations across Italy. Fresh, individual faecal samples were collected from 267 cats, kept in different environments (i.e., private households, breeding structures, municipal catteries and colonies) in three different sites across Italy. The faecal samples were tested by PCR to detect T. foetus. Moreover, the same samples were subjected to a concentration-flotation technique and a commercial direct fluorescent-antibody (DFA) test to detect additional enteric parasites, including Giardia duodenalis. The overall prevalence of T. foetus infection was 5.2%. All the infected cats showed diarrhoea at the time of sampling: 9 out of 14 positive cats were co-infected with G. duodenalis, 1 with Toxocara cati and 3 with Dipylidium caninum. The risk factor analysis showed that not only the breed, but also co-infections with G. duodenalis and Dipylidium caninum were significantly associated with the presence of T. foetus. This study confirms the presence of T. foetus in cats living in Italy, suggesting that this protozoan parasite should always be included in the differential diagnosis of patients referred with large-bowel disease symptoms, especially if they were purebred animals, or affected by other enteric protozoa, such as G. duodenalis.

Erectile dysfunction in 1050 men following extended (18 cores) vs saturation (28 cores) vs saturation plus MRI-targeted prostate biopsy (32 cores).

Erectile dysfunction (ED) following transperineal prostate biopsy (TPB) was prospectively evaluated. From January 2011 to January 2014, 1050 patients were submitted to TPB: 18 core (extended TPB) in 610 cases, 28 core (saturation TPB) in 360 cases and 32 core (saturation plus magnetic resonance imaging (MRI) targeted TPB) in 210 cases. The indications for biopsy were increasing prostate-specific antigen (PSA) or PSA>10 ng ml(-1). All patients were prospectively evaluated with the 5-item version of the International Index of Erectile Function (IIEF-5) at time zero and at 1, 3 and 6 months from TPB. Prostate cancer was diagnosed in 385/1050 (36.6%) patients; 560 men (350 vs 110 vs 100) having benign histology and normal sexual activity also completed the study. Overall, IEEF-5 score at time zero and at 1, 3 and 6 months did not significantly worsen (P>0.05); in detail, at 1 month from biopsy 15 extended TPB (4.2%) vs 7 saturation TPB (6.4%) vs 7 saturation plus MRI targeted TPB (7%) men referred mild ED that disappeared after 3 months. Irrespective of method (18 vs 28 vs 32 core) TPB did not significantly worsen erectile function at 3-6 months from the procedure.

Carcinosarcoma of the Female Urethra.

Carcinosarcoma is a rare malignant tumor with a biphasic morphology characterized by the presence of a malignant epithelial and mesenchymal component. It has been reported in many organs, including the genitourinary tract. We describe a case of a 47-year-old woman admitted to our hospital for history of recurrent urinary tract infection, dysuria and discharge of bloody fluid from the urethra at the end of urination. A tender palpable mass under the anterior vaginal wall was found and pathological examination showed a urethral carcinosarcoma. The histopathogenetic hypothesis and clinical management were considered in this report.

Analytical approaches to the diagnosis and treatment of aging and aging-related disease: redox status and proteomics.

Basal levels of oxidants are indispensible for redox signaling to produce adaptive cellular responses such as vitagenes linked to cell survival; however, at higher levels, they are detrimental to cells, contributing to aging and to the pathogenesis of numerous age-related diseases. Aging is a complex systemic process and the major gap in aging research reminds the insufficient knowledge about pathways shifting from normal "healthy" aging to disease-associated pathological aging. The major complication of normal "healthy" aging is in fact the increasing risk of age-related diseases such as cardiovascular diseases, diabetes mellitus, and neurodegenerative pathologies that can adversely affect the quality of life in general, with enhanced incidences of comorbidities and mortality. In this context, global "omics" approaches may help to dissect and fully study the cellular and molecular mechanisms of aging and age-associated processes. The proteome, being more close to the phenotype than the transcriptome and more stable than the metabolome, represents the most promising "omics" field in aging research. In the present study, we exploit recent advances in the redox biology of aging and discuss the potential of proteomics approaches as innovative tools for monitoring at the proteome level the extent of protein oxidative insult and related modifications with the identification of targeted proteins.

Transcranial magnetic stimulation in the assessment of motor cortex excitability and treatment of drug-resistant major depression.

Major depression is one of the leading causes of disabling condition worldwide and its treatment is often challenging and unsatisfactory, since many patients become refractory to pharmacological therapies. Transcranial magnetic stimulation (TMS) is a noninvasive neurophysiological investigation mainly used to study the integrity of the primary motor cortex excitability and of the cortico-spinal tract. The development of paired-pulse and repetitive TMS (rTMS) paradigms has allowed investigators to explore the pathophysiology of depressive disorders and other neuropsychiatric diseases linked to brain excitability dysfunctions. Repetitive transcranial magnetic stimulation has also therapeutic and rehabilitative capabilities since it is able to induce changes in the excitability of inhibitory and excitatory neuronal networks that may persist in time. However, the therapeutic effects of rTMS on major depression have been demonstrated by analyzing only the improvement of neuropsychological performance. The aim of this study was to investigate cortical excitability changes on 12 chronically-medicated depressed patients (test group) after rTMS treatment and to correlate neurophysiological findings to neuropsychological outcomes. In detail, we assessed different parameters of cortical excitability before and after active rTMS in the test group, then compared to those of 10 age-matched depressed patients (control group) who underwent sham rTMS. In line with previous studies, at baseline both groups exhibited a significant interhemispheric difference of motor cortex excitability. This neurophysiological imbalance was then reduced in the patients treated with active rTMS, resulting also in a clinical benefit as demonstrated by the improvement in neuropsychological test scores. On the contrary, after sham rTMS, the interhemispheric difference was still evident in the control group. The reported clinical benefits in the test group might be related to the plastic remodeling of synaptic connection induced by rTMS treatment.

Osteoblastoma of cervical spine causing an unusual neck pain.

Osteoblastoma is a rare benign tumor of bone that accounts for approximately 1% of primary skeletal neoplasms, with around 90% of cases diagnosed in the second and third decades of life. Cervical spine is an usual localization of osteoblastoma. The main clinical manifestation in case of cervical spine location is a progressive and resistant pain, possibly accompanied by stiffness, scoliosis or other ailments, including severe neurological deficits. Owing to a non-specific clinical presentation of osteoblastoma, the delay in diagnosis is common. Osteoblastomas may have an aggressive behavior, tend to enlarge and damage the bone and adjacent structures. The treatment of choice is, therefore, a wide and complete surgical excision of the lesion in order to achieve full recovery and prevent recurrence or, in some cases, malignant transformation. In the case of persistent neck pain, not readily relieved by aspirin and possibly accompanied by stiffness, scoliosis or neurological deficits, especially in young subjects, osteoblastoma of cervical spine may be one of the diagnostic options to be considered, in order to avoid delay in diagnosis. We report the case of a 41-year-old male affected by cervical spine osteoblastoma causing a lasting neck pain.

An integrated computer-controlled system for assisting researchers in cortical excitability studies by using transcranial magnetic stimulation.

Transcranial magnetic stimulation (TMS) is the most important technique currently available to study cortical excitability. Additionally, TMS can be used for therapeutic and rehabilitation purposes, replacing the more painful transcranial electric stimulation (TES). In this paper we present an innovative and easy-to-use tool that enables neuroscientists to design, carry out and analyze scientific studies based on TMS experiments for both diagnostic and research purposes, assisting them not only in the practicalities of administering the TMS but also in each step of the entire study's workflow. One important aspect of this tool is that it allows neuroscientists to specify research designs at will, enabling them to define any parameter of a TMS study starting from data acquisition and sample group definition to automated statistical data analysis and RDF data storage. It also supports the diagnosing process by using on-line support vector machines able to learn incrementally from the diseases instances that are continuously added into the system. The proposed system is a neuroscientist-centred tool where the protocols being followed in TMS studies are made explicit, leaving to the users flexibility in exploring and sharing the results, and providing assistance in managing the complexity of the final diagnosis. This type of tool can make the results of medical experiments more easily exploitable, thus accelerating scientific progress.
