The concentrations of total calcium, zinc, copper, and iron in the cyst fluid were below the reference values in canine blood whereas the concentrations of magnesium, phosphorus, sodium, and potassium in the cyst fluid were comparable to pertaining blood levels.A male dog with benign prostatic hyperplasia and several small intraprostatic cysts was treated with a GnRH-agonist implant containing 4,7 mg deslorelin (Suprelorin®). Within 2 weeks after the implantation, the prior urethral bleeding worsened. A large intraprostatic cyst was detected sonographically. The patient was subsequently treated with osaterone acetate (0.4 mg/kg p. o. once a day for 7 days) and enrofloxacin (5 mg/kg p. o. once a day for 21 days). The clinical symptoms receded within 10 days. Within one month, the cyst regressed completely. The mechanisms of cyst enlargement are discussed.Antigestagens (antiprogestins) are functional competitors of progesterone (P4) that prevent P4 from mediating its biological functions either by suppressing its production or blocking its function. Among the latter are progesterone antagonists, competitors of P4 binding to its nuclear receptor PGR, which have found application in both human and veterinary medicine, in particular in small animal practice for the prevention of nidation and the interruption of pregnancy. Depending on their mode of action, progesterone receptor antagonists can be divided into 2 classes. Class I antagonists bind to the PGR but fail to induce its binding to promoters of target genes (competitive inhibitors). Class II antigestagens, including aglepristone used in veterinary medicine, bind to the PGR, activate its association with a promoter, but interfere with the downstream signalling cascades, e. g., by recruiting transcriptional repressors. They act thereby as transdominant repressors exerting negative effects on target gene expression. Importantly for experimental sciences, as active antagonists, class II antagonists do not require the presence of the natural ligand for their action. Besides their clinical application, antigestagens are used in research for investigating P4-dependent physiological and pathological processes. Here an overview of the history and the current usage of progesterone receptor antagonists in veterinary medicine and research is presented.The availability of GnRH agonist implants offers the possibility of a reversible, temporary downregulation of endocrine and germinative testicular function in male dogs and hobs. This review provides an overview of the registered indication, the induction of temporary infertility in healthy, intact, sexually mature male dogs (4.7 and 9.4 mg deslorelin) and hobs (9.4 mg deslorelin) as well as various off-label indications. Off-label use requires strict indications, informed consent from the owner and a lack of licensed medication (safe and optimum effect). Off-label indications in the male dog include sexual-hormone dependant (disturbing) behavior, benign prostatic hyperplasia, small adenomas of the hepatoid glands and alopecia X. Successful use of deslorelin implants for estrus suppression in jils, but also for the treatment of hyperadrenocorticism in ferrets in general have been described. Similarly, hormonal castration can be induced in tomcats and queens. The variable time to onset of effect and its duratis well as the modulation of specific behavior in turkeys and an efficacy in facilitating their keeping (i. e. reduction of aggression). In reptiles, only the successful use of deslorelin in iguana has been demonstrated to date.

Measurement of steroid hormones in skin appendages such as mammalian hair or claws and in avian feathers represents a recognized non-invasive method for the determination of these parameters. The aim of this pilot study in the Gila Monster was to investigate whether the measurement of sex steroids in shed skin may be employed for the monitoring of endocrine gonadal function or sex determination in reptiles.

Shed skins were available from 11 female and 7 male adult and sexually mature animals. Large pieces of skin were initially cut into smaller pieces with scissors. The resultant dermal fragments were finely ground under liquid nitrogen and finally extracted with organic solvents. The following parameters were determined radioimmunologically in the dried and re-dissolved extracts progesterone (P4), estradiol-17β (E2), testosterone (T), free total estrogens (fGÖ) and free plus conjugated total estrogens (fkGÖ).

For P4 (p = 0.0052) and E2 (p = 0.0079) significant sex differences were found with higher conn-invasive sex determination or endocrine gonadal function assessment in certain reptile species.

Cross-reactive carbohydrate determinants (CCD) cause false positive/clinically irrelevant results in seasonal in vitro allergy tests due to the binding of immunoglobulin IgE against CCD (anti-CCD IgE).There is no study regarding the presence of this phenomen in cats. The aim of this study was to investigate the prevalence of polysensitization in serum samples and evaluate the impact of a CCD inhibitor/blocker in multi-positive seasonal allergy test results in cats.

A total of 472 feline sera, submitted from July 2017 to June 2018 for seasonal in vitro allergy test via ELISA Fc-Ε receptor technology, were studied. Samples were grouped into polysensitized (group A) and non-polysensitized (group B). Polysensitized samples (A) were retested after adding a modified glycoprotein plants extract (blocker). To determine the impact of the blocking to each allergen, the results in 48 randomly selected samples in cats prior- and post-blocking were investigated.

Polysensitization to seasonal allergens was diagnosed lergens during allergen-specific immunotherapy (ASIT).

Knowledge of cross-reactions in food-sensitive dogs will influence the choice of elimination diets and the long-term management of those patients. The objective of this study was to evaluate food allergen-specific IgE tests of suspected allergic dogs for concurrent positive reactions as possible evidence for cross reactions between allergens.

Results of serum IgE tests from 760 suspected allergic dogs submitted to 2 laboratories were evaluated statistically. After the tested allergens were grouped by their phylogenetic relationship, odds ratios as well as a sensitivity analysis of the odds ratios were performed to evaluate if concurrent positive IgE results to 2 allergens occurred more often than expected.

Within related allergen pairs 27% (laboratory 1) and 72% (laboratory 2) of the pairs could be considered as associated. For the unrelated allergen pairs only 6.8% and 10.6% of the analyzed pairs were considered associated respectively. Strong correlations were shown in the group of ruminant allergens, especially beef and lamb, and grain allergens. High rates of concurrent reactions were also detected in the poultry group, especially between chicken and duck, as well as between pork and ruminant allergens, and soy and grain allergens.

As our results showed not only correlations within related but also between non-related allergens, the possible relevance of carbohydrate moieties as well as panallergens for canine hypersensitivities warrants further study. Further investigations are necessary to distinguish co-sensitization from cross-reactions and determine the clinical relevance of food-specific IgE reactivity.

Due to possible cross reactivity related allergens, especially beef and lamb as well as grain allergens, should not be used for an elimination diet to avoid false results.

Aztreonam is a monobactam stable to hydrolysis by metallo-β-lactamases (MBLs) and avibactam is a non-β-lactam β-lactamase inhibitor that effectively inhibits serine carbapenemases (CPs). Aztreonam/avibactam is under clinical development for treatment of serious infections caused by Gram-negative bacteria, including MBL-producers.

To evaluate the in vitro activity of aztreonam/avibactam against clinical Enterobacterales isolates.

8787 Enterobacterales were collected consecutively from 64 medical centres located in Western Europe (W-EU; n = 4616; 26 centres in 10 nations), Eastern Europe (E-EU; n = 1554; 11 centres in 9 nations), the Asia-Pacific region (APAC; n = 1456; 17 centres in 9 nations), and Latin America (LATAM; n = 1161; 10 centres in 6 nations). Susceptibility tests were performed by reference broth microdilution methods and interpreted according to EUCAST criteria.

99.9% of isolates were inhibited at aztreonam/avibactam MIC of ≤8 mg/L (MIC50/90, ≤0.03/0.12 mg/L), including 99.7% of carbapenem-resistant (CRE; n = 396; MIC50/90, 0.25/0.5 mg/L) and 99.7% of multidrug-resistant isolates (n = 1706; MIC50/90, 0.06/0.5 mg/L). CRE rates were 1.2%, 12.9%, 5.2%, and 5.8% in W-EU, E-EU, APAC, and LATAM, respectively (4.5% overall). A CP was identified in 90.2% of CRE isolates. The most common CPs were variants of KPC (35.9% of CRE), NDM (29.0%), and OXA-48 (26.8%). The highest aztreonam/avibactam MIC value among MBL-producers (n = 110; MIC50/90, 0.12/0.5 mg/L) was 2 mg/L. Susceptibility rates for ceftriaxone, meropenem, levofloxacin, and amikacin were highest in W-EU (80.9%, 99.0%, 80.7% and 97.9%, respectively) and lowest in E-EU (52.0%, 88.9%, 54.1%, and 84.2%, respectively).

Our results support clinical development of aztreonam/avibactam to treat infections caused by Enterobacterales, including MBL-producers.

Understanding policy non-decisions can be assisted by identifying power operating in relevant decision-making spaces, but trade and health research rarely explicitly engages with theories of power. This realist review aimed to synthesize evidence of different forms and mechanisms of power active in trade and health decision-making spaces to understand better why NCD policy non-decisions persist and the implications for future transformative action. We iteratively developed power-based theories explaining how transnational health-harmful commodity corporations (THCCs) utilize the international trade regime to encourage NCD policy non-decisions. To support theory development, we also developed a conceptual framework for analysing power in public health policymaking. We searched six databases and relevant greyand health policy spaces that enable THCCs to prevent progressive action on NCDs. It also points to potential strategies for challenging these power dynamics and relations.Zebrafish gonadal sexual differentiation is an important but poorly understood subject. Previously, we have identified a novel insulin-like growth factor (Igf) named insulin-like growth factor 3 (Igf3) in teleosts. The importance of Igf3 in oocyte maturation and ovulation has been recently demonstrated by us in zebrafish. In this study, we have further found the essential role of Igf3 in gonadal sexual differentiation of zebrafish. A differential expression pattern of igf3 between ovary and testis during sex differentiation (higher level in ovary than in testis) was found in zebrafish. An igf3 knockout zebrafish line was established using TALENs-mediated gene knockout technique. Intriguingly, all igf3 homozygous mutants were males due to the female-to-male sex reversal occurred during sex differentiation. Further analysis showed that Igf3 did not seem to affect the formation of so-called juvenile ovary and oocyte-like germ cells. Oocyte development was arrested at primary growth stage, and the ovary was gradually sex-reversed to testis before 60 day post fertilization (dpf).
