Rates of gain and feed efficiency are important traits in most breeding programs for growing farm animals. The rate of gain (GAIN) is usually expressed over a certain age period and feed efficiency is often expressed as residual feed intake (RFI), defined as observed feed intake (FI) minus expected feed intake based on live weight (WGT) and GAIN. However, the basic traits recorded are always WGT and FI and other traits are derived from these basic records. The aim of this study was to develop a procedure for simultaneous analysis of the basic records and then derive linear traits related to feed efficiency without retorting to any approximation. A bivariate longitudinal random regression model was employed on 13,791 individual longitudinal records of WGT and FI from 2,827 bulls of six different beef breeds tested for their own performance in the period from 7 to 13 mo of age. Genetic and permanent environmental covariance functions for curves of WGT and FI were estimated using Gibbs sampling. Genetic and permtaneously, and the set of parameters is consistent.

Does ultra-long downregulation with a GnRH agonist (triptorelin depot) in previously operated patients with endometriosis improve the rate of clinical pregnancy with positive fetal heart beat (CPHB) in the subsequent initiated fresh ART cycle?

Ultra-long downregulation with a GnRH agonist prior to ART did not improve the rate of CPHB in the subsequent fresh ART cycle in previously completely operated patients but the trial was underpowered due to early termination.

Administration of GnRH agonists for a period of 3-6 months prior to ART in women with endometriosis may increase the odds of clinical pregnancy. learn more However, the quality of the studies on which this statement is based is questionable, so these findings need confirmation.

A controlled, randomized, open label trial was performed between 1 June 2013 and 31 December 2016 (start and end of recruitment, respectively). Patients with prior complete laparoscopic treatment of any type or stage of endometriosis and an indication for ART were randomized (bMarch 2013.

4 September 2013.This study aimed to retrospectively describe the clinical progression following diagnosis of iatrogenic hypocortisolemia (iHC) in 48 dogs receiving trilostane for pituitary-dependent hyperadrenocorticism. Cortisol concentrations were ≥1.5 mg/dL within 6 mo following diagnosis of iHC in 76.3% of dogs (95% confidence interval [CI] 59.8-88.6%). At the time of study completion, 25% of dogs (95% CI 13.6-39.6%) were receiving either glucocorticoids or mineralocorticoids or both; 42% of dogs (95% CI 27.6-56.8%) were on no adrenal-related medications; and the remaining 33% of dogs (95% CI 20.4-48.4%) were receiving trilostane. No patient-, clinicopathologic-, or trilostane-associated factors were identified to influence adrenal recovery following diagnosis of iHC, and it remains difficult to predict the clinical progression in this population of dogs.An 8 mo old male Doberman pinscher was referred for investigation of persistent urinary incontinence. Physical examination revealed urine leakage and abnormal external genitalia. A computed tomography scan identified a large fluid-filled cavity extending from the caudoventral abdomen displacing the colon and urinary bladder. No retained testicles were identified. A retrograde urethrogram study found a linear communication, cranial to the pubic brim between the urethra to the fluid-filled cavity (fistula). Exploratory celiotomy was performed, and an entire female reproductive tract with a blind-ending vagina and a urethrovaginal fistula was found. En bloc gonad hysterectomy was performed, the fistula was transected, and a careful urethral reconstruction was performed. The urinary incontinence resolved immediately after surgery, and no complications were reported. Mild urinary incontinence recurred 4 days following patient discharge, and a urine bacterial culture was positive for Klebsiella spp. An antibiotic course was prescribed, and the incontinence fully resolved. Congenital urogenital abnormalities should always be considered in young animals presenting with urinary incontinence. Here, a young female pseudohermaphrodite dog with a naturally occurring congenital urethrovaginal fistula is described. Exploratory surgery was required for definitive diagnosis and surgical intervention yielded a good medium-term outcome with resolution of clinical signs.Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis (SJS/TEN) are life-threatening conditions best approached with multidisciplinary burn-equivalent care. There is a lack of consensus on wound management, in particular whether to debride detached epidermis. Our center instituted "antishear" wound therapy thirty-five years ago, where detached skin is left in situ as a biologic dressing and a standardized protocol avoids shear forces to prevent further desquamation. Our center's initial results showed outcomes comparable to SCORTEN predictions, but advancements in burn critical care necessitate a re-evaluation of the antishear approach. A retrospective chart review was conducted for all patients admitted between 06/2004 to 05/2020 with a dermatologist-confirmed diagnosis of SJS/TEN (N=51). All patients were treated with burn-equivalent critical care and antishear wound therapy. Standardized mortality ratios were calculated using the established SCORTEN, and newly developed ABCD-10, prediction models. Mean SCORTEN, ABCD-10, and %TBSA were 2.6, 2.0, and 28%. Overall mortality was 22%; SCORTEN score (p3; across the cohort it was 0.71 (p=0.11), representing a 29% mortality reduction. Incorporating the antishear approach as part of burn-equivalent care for SJS/TENS led to outcomes comparable to those predicted for surgical debridement via SCORTEN. However, the antishear approach has the advantage of avoiding painful dressing changes, sedation, and general anesthesia required for surgical debridement.Polybrominated diphenyl ethers (PBDEs) have been previously shown to alter various endocrine biosynthetic pathways. Growing epidemiological evidence suggests that PBDEs alter cardiovascular function. The goal of this study was to examine the effects of BDE-47 on adrenal corticosteroid pathways that play vital roles in cardiovascular homeostasis and pathophysiology. The effect of BDE-47 on aldosterone and cortisol secretion was characterized in a human adrenocortical cell line. HAC15 cells were exposed to various concentrations of BDE-47 (1 nM to 100 μM). Cell viability, corticosteroid secretion, gene expression of enzymes involved in corticosteroid synthesis, and metabolic activity was examined. Additionally, Sprague Dawley male rats were orally exposed to BDE-47 (10 or 100 µg/kg), 5 days per week for 16 weeks. Organ weights and plasma corticosteroid levels were measured. In HAC15 cells, basal and stimulated aldosterone and cortisol secretion was significantly increased by BDE-47. Gene expression of several enzymes involved in corticosteroid synthesis and mitochondrial metabolism also increased. In Sprague Dawley rats, adrenal but not heart, kidney, or liver weights, were significantly increased in BDE-47 treatment groups. Plasma corticosterone levels were significantly increased in the 100 µg BDE-47/kg treatment group. No change in plasma aldosterone levels were observed with BDE-47 exposure. These data indicate that BDE-47 disrupts the regulation of corticosteroid secretion and provides further evidence that PBDEs are potential endocrine disruptors. Future studies will determine the underlying molecular mechanism of altered corticosteroid production and examine whether these alterations result in underlying cardiovascular disease in our rodent model of 16-week BDE-47 exposure.The purpose of this retrospective study was to compare outcome measures in dogs treated by a primary care veterinarian (pcDVM) before referral and after seeking collaboration with a board-certified veterinary dermatologist (BCVD) for cases of severe recurrent chronic otitis externa. Medical records of 65 client-owned dogs were retrospectively reviewed, and data were obtained regarding treatment history, referral timeframe, recurrence rate, clinical signs, and resolution of signs. The median number of otitis recurrences while under the care of the pcDVM was 4 (range 1-40) versus collaborative BCVD care of 2 (P .01). Proliferative changes in the ear canals improved in 41/45 (91%) of cases under BCVD care compared with 6/45 (13%) under care by the pcDVM (P less then .01). Dogs with chronic otitis had better long-term outcomes when collaboration with a BCVD was pursued within 6 mo of treatment. Referral or consultation with a BCVD should be considered for cases of chronic canine otitis that are persistent or quickly recurrent (20-30 days) over a 6 mo period.An 11 yr old mixed-breed dog presented with a 2 × 3 cm semimovable subcutaneous soft-tissue mass overlying the right hip region that grew to 8 × 5 cm over a 6 mo period. Two separate fine needle aspiration cytology samples showed marked pyogranulomatous inflammation with no cytologically apparent infectious etiology or neoplasia. Computed tomography imaging revealed a well-marginated, heterogeneous, contrast-enhancing soft-tissue mass extending into the adjacent fat, suggestive of neoplasia. A 14G needle biopsy showed similar chronic inflammatory changes without evidence of neoplasia or infectious etiology. Excisional biopsy of the mass was performed, and ex vivo sectioning revealed Taenia crassiceps cysticerci. Histopathology confirmed severe chronic pyogranulomatous cellulitis and myositis with intralesional cysticerci. Anthelmintic treatment was administered postoperatively, and no evidence of local recurrence has been noted as of 6 mo after the operation. To our knowledge, this is the first case report describing the cytological, histological, cross-sectional imaging characteristics and treatment outcome of T crassiceps cysticercosis in a dog.Packed cell volume (PCV) is commonly used to assess and monitor red blood cell count in animals, but the results can be altered if inappropriate ratios of anticoagulant/blood are used. The purpose of this study was to determine the effect of ideally filled, overfilled, and underfilled K3 ethylenediaminetetraacetic acid (EDTA) tubes with various volumes of healthy dog blood on centrifuged PCV. Six milliliters of blood was obtained from 94 blood donors each. Initial distribution was injected into two nonheparinized microhematocrit tubes. The remainder was instilled into 1.3 mL K3 EDTA spray-dried tubes as 1.5 mL, 1.3 mL, 0.75 mL, 0.5 mL, and 0.25 mL aliquots. Normality was determined using the D'agostino-Pearson method and by visual examination of histograms. Data were analyzed using a repeated-measures analysis of variance with post hoc testing using Tukey's test. There is a statistically significant decrease in the PCV between all groups with progressive underfilling of tubes (P less then .0001). The closest difference is between 1.5 and 1.3 mL (P = .0138). Our study suggested that underfilling K3 EDTA tubes significantly and negatively influences the PCV in healthy dogs. Using underfilled K3 EDTA tubes result in a lower PCV compared with directly filled microhematocrit tubes without anticoagulant.
