RESULTS Hospitals on average received $3682 (30%) lower payment from Medicare for outpatient TKA cases, but this varied widely across hospitals. The difference in payment rates across hospitals was not statistically significantly related to their adoption rate of outpatient TKAs. PAC spend was higher for same-day discharges, but lower for cases that stayed at least 1 night. Based on the adoption rate of outpatient TKAs in Q2 2019, Medicare saved $355M on a run rate basis. CONCLUSION Hospitals have adopted outpatient TKAs independent of the financial impact. Medicare has benefited from lower PAC spend and lower payments to hospitals. BACKGROUND The Centers for Medicare and Medicaid Services removed total knee arthroplasties (TKAs) from the inpatient-only (IPO) list on January 1, 2018, which meant that TKAs could be performed on a hospital outpatient basis. We examined the following (1) the national rate of adoption of outpatient TKAs over time, (2) how adoption varied across hospitals, and (3) whether adoption of outpatient TKAs has positively or negatively impacted 90-day TKA readmission rates. METHODS We used national patient-level Medicare Fee-for-Service Part A claims data (100% sample) from January 2017 through June 2019 to look at the quarterly trend in percent of TKAs performed as outpatient, and the distribution in this percentage across hospitals in the country. We ran a case-level regression to understand whether inpatient vs outpatient coding status relates to 90-day readmission rates. RESULTS In 2017 prior to the removal of TKAs from the IPO list, 0.2% were performed as outpatient. Adavosertib datasheet In the first quarter (Q1 2018) after the rule change, 24.9% were performed as outpatient, and by the second quarter of 2019, 36.4% were performed as outpatient. These rates varied widely across hospitals from 0% (10th and 25th percentiles) to 78% (90th percentile) from January 2018 through March 2019. There was no difference in readmission rates for same-day discharges, but outpatient cases discharged after one or more nights in the hospital had statistically lower readmissions than inpatient cases. CONCLUSION There was a rapid increase in the adoption of hospital outpatient TKAs following their removal from the Medicare IPO, which has resulted in lower readmission rates, and so adoption is likely to continue. BACKGROUND The purpose of this study is to investigate outcomes of patients denied total hip (THA) or knee arthroplasty (TKA) due to morbid obesity. METHODS We performed an observational study of patients denied arthroplasty due to morbid obesity. A survey including the Harris Hip Score or pain and function components of the original Knee Society Score (KSS) was conducted with minimum 2-year follow-up. Statistical analysis was performed with parametric testing with significance at P less then .05. RESULTS In total, 125 (4.4%) of 2819 patients were denied THA or TKA due to morbid obesity. Twenty-four (19.2%) met target weight and underwent arthroplasty at our institution. Of the remaining 101 (80.8%) patients, 33 (32.7%) agreed to participate in the survey. None received THA and 6 received TKA elsewhere above target body mass index. Harris Hip Score was significantly higher in the successful weight loss cohort at our institution (70.5 ± 13.4 vs 34.6 ± 13.1). KSS Pain (maximum score of 50) and Function (maximum score of 100) were significantly higher in the successful weight loss cohort at our institution (32.9 ± 16.5; 51.1 ± 19.5) compared to the denied nonoperative cohort (7.2 ± 11.5; 33.0 ± 23.1); however, only KSS Pain was higher when compared to the TKA elsewhere cohort (14.2 ± 18.0; 29.2 ± 38.7). KSS Pain and Function were similar for both denial cohorts regardless of undergoing arthroplasty. CONCLUSION Nearly 80% of patients denied never met target weight for arthroplasty. Those who met target weight prior to arthroplasty often reported better outcomes. Outcomes were similar when target weight was not met regardless of undergoing arthroplasty. End-of-life tyre (ELT)-derived rubber granules are used as synthetic turf infill on sports fields. They contain various chemical substances and there are concerns that exposure to these substances might be harmful for human health. This Europe-wide risk assessment study addresses these concerns. As the first part, chemical substances in samples from recycling companies and from sports fields were analysed. 86 coated and non-coated ELT granule samples from sites in 14 European countries were investigated, together with ten non-ELT materials. An extensive list of potentially relevant substances was compiled, and the infill materials were analysed for these substances, using GC and HPLC methods. Volatilisation of substances was studied in emission chambers. Polycyclic aromatic hydrocarbons (sum of 8 REACH PAHs) were identified at average concentrations below 10 mg/kg. Substances found at higher concentrations in rubber granules were aluminium (arithmetic mean in uncoated samples from sports fields 5383 mg/kg) and cobalt (168 mg/kg), benzothiazole (48 mg/kg) and 2-hydroxybenzothiazole (34 mg/kg), 6PPD (571 mg/kg) and DPG (51 mg/kg), and 4-tert-octylphenol (14 mg/kg). In addition, the following volatiles were found to evaporate from crumb rubber in emission chambers benzothiazole, tert-butylamine, cyclohexanone, methyl isobutyl ketone, 2-heptanone and saturated aliphatic hydrocarbons higher than C9. With this comprehensive survey we created a profound database on concentrations of chemical substances in ELT-derived infill material, which is essential for a reliable risk assessment. The results were used to inform subsequent investigations (migration studies, exposure monitoring survey). The first 7 days post-insemination are critical for establishment of pregnancy. The pre-ovulatory luteinizing hormone (LH) surge induces ovulation through disruption of the follicle structure that elucidates pro-inflammatory (Th1) responses. Various types of immune cells are recruited into the corpus luteum (CL) to regulate luteal angiogenesis and progesterone (P4) secretion into the circulation to establish pregnancy. The active sperm-uterine crosstalk also induces Th1 responses, mainly via Toll-like receptor (TLR) 2/4 signaling pathway in vitro. The endometrial glands serve as sensors for sperm signals, which trigger Th1 responses. Conversely, the sperm-oviduct binding generates anti-inflammatory (Th2) responses to support sperm survival until fertilization. It is well-established that embryo-maternal crosstalk starts after the embryo hatches out from the zona pellucida (ZP). However most recently, it was shown that the 16-cell stage bovine embryo starts to secrete interferon-tau (IFNT) that induces Th2 immune responses in the oviduct. Once developing embryos descend into the uterine horn, they induce Th2 responses with interferon-stimulated genes (ISGs) expression in the uterine epithelium and local immune cells mainly via IFNT release. Likewise, multiple embryos in the uterus of superovulated donor cows on D7 post-insemination induce Th2 immune responses with ISGs expressions in circulating immune cells. These findings strongly suggest that the maternal immune system reacts to the embryo during the first 7 days post-insemination to induce fetal tolerance. It became evident that the innate immunity of the developing CL, oviduct, and uterus works together to provide optimal conditions for fertilization and early embryonic development during the first 7 days post-insemination. Previously, we reported the first live births of dogs using in vitro fertilization (IVF), embryo cryopreservation, and transfer. These techniques have potential applications in the conservation of endangered canids, and development of gene editing/repair technologies that could improve animal welfare by restoring normal gene function and removing predisposition to disease. Here, we used IVF as a springboard for initial attempts at genetic modification through gene editing/repair using the Clustered Regularly-Interspaced Short Palindromic Repeat (CRISPR)-CRISPR-associated endonuclease (Cas9) system. We showed previously that timing is critical for successful IVF in that the canine oocyte must be exposed to the oviductal environment beyond simply reaching metaphase II. Others have shown that timing of injection of CRISPR-Cas9 constructs is critical in gene editing, influencing the extent of genetic mosaicism. Therefore, we investigated whether timing of injection of the gene editing/repair constructs might influence the success of embryo production and gene editing in the dog. We achieved similar IVF success to our prior report in generating 2-cell control embryos, and found equally reduced embryo production whether injection was performed in oocytes prior to fertilization, or in presumptive single-cell zygotes already exposed to sperm. We had no success at generating offspring with precise single-nucleotide changes in KRT71 via homology-directed repair (HDR), but did identify mutation of FGF5 using non-homologous end joining (NHEJ). These findings underscore the difficulties inherent to gene repair, but represent important progress on reproducibility of canine IVF, improved techniques of oocyte/embryo handling, and impact of timing of injections on embryo development. The ovulation-inducing effect of seminal plasma was first suggested in Bactrian camels over 30 years ago, initiating a long search to identify the 'ovulation-inducing factor' (OIF) present in camelids semen. During the last decade, primarily in llamas and alpacas, this molecule has been intensively studied characterizing its biological and chemical properties and ultimately identifying it as β-Nerve Growth Factor (β-NGF). The high concentration of OIF/β-NGF in seminal plasma of llamas and alpacas, and the striking effects of seminal fluid on ovarian function strongly support the notion of an endocrine mode of action. Also, have challenged the dogma of mating induced ovulation in camelid species, questioning the classical definition of reflex ovulators, which at the light of new evidence should be revised and updated. On the other hand, the presence of OIF/β-NGF and its ovulatory effect in camelids confirm the notion that seminal plasma is not only a transport and survival medium for sperm but also, a signaling agent targeting female tissues after insemination, generating relevant physiological and reproductive consequences. The presence of this molecule, conserved among induced as well as spontaneous ovulating species, clearly suggests that the potential impacts of this reproductive feature extend beyond the camelid species and may have broad implications in mammalian fertility. The aim of the present review is to provide a brief summary of all research efforts undertaken to isolate and identify the ovulation inducing factor present in the seminal plasma of camelids. Also to give an update of the current understanding of the mechanism of action of seminal β-NGF, at central and ovarian level; finally suggesting possible brain targets for this molecule. Knowledge of and the technologies and resources applied to the ex situ care for wildlife have improved greatly in recent years. This has resulted in numerous successes bringing back populations from the brink of extinction by the reintroduction or restoration of animals from conservation breeding programmes. Controlled breeding of wildlife by humans is discussed controversially in society and in scientific circles and it faces a number of significant challenges. When natural breeding fails, Assisted Reproduction Technologies (ART) have been postulated to increase reproductive output and maintain genetic diversity. Furthermore, technical advances have improved the potential for successful collection and cryopreservation of gametes and embryos in many wildlife species. With the aim of creating a better understanding of why ex situ and in situ conservation of threatened species must complement each other, and under which circumstances ART provide additional tools in the rescue of a threatened population, we elucidate the current situation here by using as examples three different megavertebrate families elephantidae, rhinoceridae and giraffidae.
