Nannizzia species causing dermatophytosis in cats and dogs: First report of Nannizzia incurvata as an etiological agent in Brazil.

Dermatophytosis is a superficial cutaneous infection, most commonly caused by fungal species such as Microsporum canis, Nannizzia gypsea (Microsporum gypseum), and Trichophyton mentagrophytes in dogs and cats. The zoonotic potential of these species is concerning, as companion animals are increasingly close to their owners. Therefore, the objectives of the study were to evaluate the current prevalence of Nannizzia-causing canine and feline dermatophytosis in Curitiba and Metropolitan Region, as well as perform phenotypic and phylogenetic characterizations of these isolates.

Efficacy and immune-related adverse event associations in avelumab-treated patients.

Background: Adverse events (AEs) of special interest that arise during treatment with immune checkpoint inhibitors, including immune-related AEs (irAEs), have been reported to be associated with improved clinical outcomes. We analyzed patients treated with avelumab from the JAVELIN Solid Tumor and Merkel 200 trials, examining the association between AEs and efficacy while adjusting for confounding factors such as treatment duration and event order.

Methods: We analyzed efficacy and safety data from 1783 patients treated with the programmed death ligand 1 inhibitor avelumab who were enrolled in expansion cohorts of the JAVELIN Solid Tumor and Merkel 200 trials.

Association between over-indebtedness and antidepressant use: A cross-sectional analysis.

Background: Burden of disease caused by depression and its association with socioeconomic status is well documented. However, research on over-indebtedness is scarce although millions of European citizens in all socioeconomic positions are over-indebted. Prior studies suggested that over-indebtedness is associated with poor physical and mental health.

Patient-physician communication about financial problems: A cross-sectional study among over-indebted individuals.

Background: About every tenth household across Europe is unable to meet payment obligations and living expenses on an ongoing basis and is thus considered over-indebted. Previous research suggests that over-indebtedness reflects a potential cause and consequence of psychosomatic health problems and limited access to care. However, it is unclear whether those affected discuss their financial problems with general practitioners.

Antimicrobial activity of topical dyes used in clinical veterinary ophthalmology.

Objective: To evaluate in vitro the antibacterial effects of fluorescein, rose bengal, and lissamine green topical ophthalmic dyes against selected Gram-positive and Gram-negative bacteria, and to evaluate whether preserved or preservative-free fluorescein solutions are able to inhibit or potentiate bacterial growth.

Procedures: Susceptibility testing was performed using the Kirby-Bauer disk diffusion method plated with clinical ocular isolates of Staphylococcus aureus, Staphylococcus pseudintermedius, Streptococcus spp., Escherichia coli, and Pseudomonas aeruginosa.

Cost-related medication nonadherence among over-indebted individuals enrolled in statutory health insurance in Germany: a cross-sectional population study.

Background: Millions of citizens in high-income countries face over-indebtedness that implies being unable to cover payment obligations with available income and assets on an ongoing basis. Studies have shown an association between over-indebtedness and health outcomes, independent of standard socioeconomic status measures. Patterns of cost-related medication nonadherence (CRN) among over-indebted individuals are yet unclear.

Over-indebtedness and its association with sleep and sleep medication use.

Background: Over-indebtedness is currently rising in high-income countries. Millions of citizens are confronted with the persistent situation when household income and assets are insufficient to cover payment obligations and living expenses. Previous research shows that over-indebtedness increases the risk of various adverse health effects.

Increased dense erythrocytes in flame-burned patients.

Objective: We have studied dense erythrocytes separated on Arabinogalactan (Stractan) ultracentrifuged gradients in flame-burned patients and in normal individuals. In each case, the percentage of erythrocytes in the densest layers was increased when compared to age and sex matched controls.

Methods And Results: Using an in vitro system, we showed that as human whole blood is warmed to 48.

Effect of neutralizing antibodies on biomarker responses to interferon beta: the INSIGHT study.

Background: Interferon beta (IFNbeta) effectively reduces disease activity in patients with multiple sclerosis (MS). Neutralizing antibodies (NAbs) can diminish or abolish the clinical efficacy of IFNbeta therapies. Biomarkers of the IFNbeta response, such as myxovirus resistance protein A (MxA), viperin, and interferon-induced protein with tetratricopeptide repeats 1 (IFIT-1), may be used to measure the in vivo effects of NAbs on IFNbeta bioactivity.

Novel presentation of a familial pancreatic cancer syndrome.

Introduction: Earlier detection of pancreatic cancer may help identify patients for whom surgical intervention could provide cure or prolong life. In this article, we report the occurrence of breast cancer, melanoma, squamous cell carcinoma of the alveolar ridge, colon cancer, a desmoid tumor of the abdominal wall, and pancreatic adenocarcinoma in a 65-year-old woman. She was identified as having the familial atypical multiple mole melanoma-pancreatic cancer syndrome (FAMMM-PC) with a germline p16 mutation at amino acid position 15.

Warfarin-induced skin necrosis in a patient with heparin-induced thrombocytopenia: two diseases or one?

A 64-year-old woman with colon carcinoma presented with subsegmental pulmonary emboli. Platelet count on presentation was 598 x10(9)/l. The patient was anticoagulated with intravenous heparin.

Virulence properties and antimicrobial susceptibility of Shiga toxin-producing Escherichia coli strains isolated from healthy cattle from Paraná State, Brazil.

The presence of Shiga toxin-producing Escherichia coli (STEC) strains in feces samples of cattle was determined using the cytotoxicity assay on Vero cells and a screening PCR system to detect stx genes. The STEC isolates were serotyped, tested for antimicrobial susceptibility, and analyzed for virulence genes using multiplex PCR. The verocytotoxin-producing E.

Nocardia asteroides-infected aneurysm of the aorta: case report and review of the literature.

Infected aneurysms of the aorta were first described as a result of septic emboli or contiguous spread from bacterial endocarditis and are usually caused by Staphylococcus or Salmonella species. We report a case of Nocardia-associated infected aneurysm of the native suprarenal aorta in an immunocompromised host. Surgical management consisted of placement of an interposition cryopreserved aortic homograft.

Simultaneous occurrence of polycythemia vera and Waldenstrom macroglobulinemia: a case report and review of the literature.

Polycythemia vera and lymphoproliferative disorders can occur simultaneously. Lymphoproliferative disorders reported to occur simultaneously with polycythemia vera include chronic lymphocytic leukemia (CLL), non-Hodgkin's lymphoma (NHL), and acute lymphoblastic leukemia (ALL). Different theories have attempted to explain this occurrence.

Angiotensin II type 1 receptor-mediated inhibition of K+ channel subunit kv2.2 in brain stem and hypothalamic neurons.

Angiotensin II (Ang II) has powerful modulatory actions on cardiovascular function that are mediated by specific receptors located on neurons within the hypothalamus and brain stem. Incubation of neuronal cocultures of rat hypothalamus and brain stem with Ang II elicits an Ang II type 1 (AT1) receptor-mediated inhibition of total outward K+ current that contributes to an increase in neuronal firing rate. However, the exact K+ conductance(s) that is inhibited by Ang II are not established.

Re-examination of Na+-dependent regulation of cAMP-dependent Cl- currents in the heart.

Cardiac Cl- channels may play an important role in both the physiological as well as the pathophysiological regulation of the heart. Due to the present controversy regarding the role that Na+ may play in the regulation of the adenosine 3',5'-cyclic monophosphate (cAMP)-dependent Cl- channels in the heart, we have re-examined the effects of intracellular and extracellular Na+ on ICl,cAMP in isolated guinea-pig ventricular myocytes. In conventional, whole-cell patch-clamp experiments, exchanging of extracellular Na+ for N-methyl-d-glucamine (NMG) did not have a significant effect on the magnitude of the ICl,cAMP activated by external forskolin (FSK) in the presence of beta-adrenergic and muscarinic receptor blockade compared with normal rundown of the current with time.

Cystic fibrosis gene encodes a cAMP-dependent chloride channel in heart.

cAMP-dependent chloride channels in heart contribute to autonomic regulation of action potential duration and membrane potential and have been inferred to be due to cardiac expression of the epithelial cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel. In this report, a cDNA from rabbit ventricle was isolated and sequenced, which encodes an exon 5 splice variant (exon 5-) of CFTR, with >90% identity to human CFTR cDNA present in epithelial cells. Expression of this cDNA in Xenopus oocytes gave rise to robust cAMP-activated chloride currents that were absent in control water-injected oocytes.

CFTR chloride channels in human and simian heart.

Objectives: The cAMP-dependent Cl- conductance in heart is believed to be due to cardiac expression of the cystic fibrosis transmembrane conductance regulator (CFTR). While CFTR expressed in rabbit and guinea-pig heart (CFTRcardiac) is an alternatively spliced isoform of the epithelial gene product, little information is known regarding possible expression of CFTR in primate heart. In this study, we examined molecular expression of CFTR in human and simian atrium and ventricle and functional expression of cAMP-dependent Cl- currents in isolated human atrial and simian ventricular cells.

A case of bleeding requiring hospitalization that was likely caused by an interaction between warfarin and levamisole.

Warfarin is one of the most commonly used oral anticoagulants. Many medications have been shown to influence the prothrombin time in patients treated with warfarin by various mechanisms. We observed a major bleeding episode that resulted from a probable interaction between levamisole (Ergamisol), 5-fluorouracil, and warfarin.

Molecular physiology of CFTR Cl- channels in heart.

Recent electrophysiological data suggests a number of similarities in the properties of cAMP-dependent Cl- channels in heart and cAMP-dependent Cl- channels encoded by the cystic fibrosis transmembrane conductance regulator (CFTR) gene product in various epithelial cells. We tested the hypothesis that cAMP-dependent Cl- channels in heart may be due to cardiac expression of CFTR by amplification and sequencing of several regions of CFTR from myocardial tissue derived from various species and areas of the heart. Regions corresponding to the first nucleotide binding domain (NBD1), transmembrane segments I-VI (TS I-VI), transmembrane segments VII-XII (TS VII-XII), and the regulatory domain (R domain) were amplified and sequenced from rabbit ventricle (see Fig.

Direct measurement of the internal viscosity of sickle erythrocytes as a function of cell density.

The rotational dynamics of TEMPAMINE can be used to study directly the intracellular environment. The extracellular signal from TEMPAMINE is broadened away by the use of potassium ferricyanide which does not enter the cell. The EPR signal which results when 1 mM TEMPAMINE, 120 mM ferricyanide, and erythrocytes are mixed together arises from TEMPAMINE only in the intracellular aqueous space.
