MiMedx accounting firm quits

The troubles at MiMedx (NSDQ:MDXG) continued last week with the resignation of the accounting firm tapped to audit its books in the wake of a financial scandal. Marietta, Ga.-based MiMedx last July ousted ex-CEO Parker Petit and president &COO William Taylor amid a board-directed independent investigation that had already prompted the departure of CFO Michael Senken and treasurer John Cranston in June. At the time, MiMedx said it would restate all of its earnings reports going back to 2012 and was cooperating with U.S. Securities &Exchange Commission and Justice Dept. investigations into the matter. The company later said that all four executives’ departures were for cause, triggering the forfeit of all equity and incentive awards for the executives and Petit’s resignation from the board. Petit and Taylor denied the allegations in a statement from their lawyer. Last week MiMedx, which makes regenerative and therapeutic biologics using human placental tissue allografts, said the company hired by its board’s audit committee resigned Dec. 4 after determining that it can’t rely on the company’s internal financial controls or the representations from the former executives and their interim replacements. “EY advised the company that the internal controls necessary for the company to develop reliable financial statements do not exist,” MiMedx said in a Dec. 7 regulatory filing. “Although EY co...

Authors: Ghaidan H, Fakhro M, Lindstedt S Abstract Purpose: The influence of allograft ischemic time (IT) on short- and long-term mortality remains under debate in lung transplantation (LTx). Due to a scarcity in donors, better understanding of IT might improve the outcome after LTx. Methods: Between January 1990 and June 2016; 307 patients underwent LTx at Lund university hospital, Sweden. The end-point used was death/Re-LTx assessed by Cox regression and Kaplan-Meier survival. Results: Kaplan-Meier survival for mean IT (min) between subgroups ≤120, 121-240, 241-360 and 361+ showed significant difference for pa...

CONCLUSIONS Collectively, the strategic and key vertebra pedicle screw schemes can decrease the biomechanical stress of screw-rod systems and vertebral bodies, which is close to the full-segment scheme. Our results may help explore the optimal surgical means for pedicle screw fixation for ADS patients, which can maximally reduce the risk of screws-related postoperative complications and simultaneously maintain a reasonable 3D orthopedic effect.

Conclusions: Staphylococcus aureus, Propionibacterium acnes, and Pseudomonas aeruginosa keratitis with or without endophthalmitis represent the most common indication for ocular enucleation/evisceration in patients with microbial keratitis in a tertiary referral center in Hungary. The incidence of enucleation and evisceration related to mycotic keratitis does not seem to have increased within the last decade. Most frequent preexisting systemic diseases in cases of enucleation and evisceration are hypertension, cardiac disease, diabetes mellitus, and rheumatoid arthritis. PMID: 32509342 [PubMed]

Abstract OBJECTIVE: The present study aimed to investigate the reliability of acellular decalcified teeth in the development of bone scaffolds and in bone regeneration in rats. METHODS: (1) Forty-eight human teeth were divided into two groups in vitro: twenty-four were decalcified, while the remaining twenty-four were decalcified and decellularized, following which a conventional scanning-electron microscope analysis was performed. (2) In another experiment, six male SD rats aged 10-12 weeks were selected, then decalcified and acellular decalcified teeth were embedded subcutaneously in the abdomen of the rats...

CONCLUSION: the increase of RI during the first weeks of the postoperative period seems to be associated with DGF and with tubular necrosis / tubular vacuolization in peri-implantation biopsies, likely related to ischemia reperfusion injury. PMID: 32459281 [PubMed - as supplied by publisher]

Abstract Background and purpose - Early postoperative implant migration predicts failure of joint replacements. Bone mineral density reflects bone quality and bone-graft incorporation. Implant migration and bone densitometry analysis usually require special equipment. We investigated cup migration and bone mineral density changes simultaneously with low-dose CT scans after acetabular revision hip arthroplasty using impaction bone grafting.Patients and methods - We performed a low-dose CT postoperatively, after 6 weeks, and after 2 years in 17 patients, all revised using impaction bone grafting and a graft-compress...
