  • Pediatric Postoperative Pulse Oximetry Monitoring During Transport to the Postanesthesia Care Unit Reduces Frequency of Hypoxemia. Joint Commission journal on quality and patient safety Caruso, T. J., Mokhtari, T. E., Coughlan, M. J., Wu, D. S., Marquez, J. L., Duan, M., Freeman, H., Giustini, A., Tweedy, M., Sharek, P. J. 2017; 43 (3): 146–50


    The standard use of pulse oximetry during the transport of postoperative patients from the operating room (OR) to the postanesthesia care unit (PACU) is not routinely practiced. A study was conducted to determine if the frequency of hypoxemia on admission to the PACU decreased after implementation of routine use of transport pulse oximeters for postoperative patients being transferred to the PACU.In this prospective cohort study, which was conducted at an academic pediatric hospital, the primary outcome measure was the frequency of hypoxemic events on arrival to the PACU.A total of 506 patients in the preintervention phase and 597 in the postintervention phase met the inclusion criteria. Six hypoxemic events on arrival to the PACU were identified in preintervention phase versus zero in the postintervention period, p = 0.009. Use of oxygen monitors during transport from the OR to the PACU increased from 0% to 100%, p < 0.0001, in the postintervention phase. The median duration of unmonitored time during transport decreased from 272 seconds to 13 seconds, p < 0.0001. Of the 605 patients who met the inclusion criteria for sustainment audits-conducted 18 months after the postimplementation evaluation-99.8% were transported to the PACU with a pulse oximeter, and there were zero reported hypoxemic patients on PACU admission.The routine use of portable oxygen monitoring when transferring patients from the OR to the PACU is a low-cost, noninvasive safety measure that should be considered at any institution performing pediatric general anesthesia.

  • Comparison of porcine and bovine collagen dural substitutes in posterior fossa decompression for Chiari I malformation in adults. World neurosurgery Lee, C. K., Mokhtari, T., Connolly, I. D., Li, G., Shuer, L. M., Chang, S. D., Steinberg, G. K., Gephart, M. H. 2017


    Posterior fossa decompression surgeries for Chiari malformations are susceptible to post-operative complications such as pseudomeningocele, external cerebrospinal fluid (CSF) leak, and meningitis. Various dural substitutes have been employed to improve surgical outcomes.This study examined whether the collagen matrix dural substitute type correlated with the incidence of post-operative complications following posterior fossa decompression in adult patients with Chiari I malformations.A retrospective cohort study was conducted on 81 adult patients who underwent an elective decompressive surgery for treatment of symptomatic Chiari I malformations, with duraplasty involving a dural substitute derived from either bovine or porcine collagen matrix. Demographics and treatment characteristics were correlated with surgical outcomes.A total of 81 patients were included in the study. Compared to bovine dural substitute, porcine dural substitute was associated with a significantly higher risk of pseudomeningocele occurrence (OR 5.78, 95% CI 1.65-27.15; P = .01) and a higher overall complication rate (OR 3.70, 95% CI 1.23-12.71; P = .03) by univariate analysis. There was no significant difference in the rate of meningitis, repeat operations, or overall complication rate between the two dural substitutes. In addition, estimated blood loss was a significant risk factor for meningitis (P = .03). Multivariate analyses again demonstrated that porcine dural substitute was associated with pseudomeningocele occurrence, though the association with higher overall complication rate did not reach significance.Dural substitutes generated from porcine collagen, compared to those from bovine collagen, were associated with a higher likelihood of pseudomeningocele development in adult patients undergoing Chiari I malformation decompression and duraplasty.

  • Mammography before and after bariatric surgery. Surgery for obesity and related diseases Mokhtari, T. E., Rosas, U. S., Downey, J. R., Miyake, K. K., Ikeda, D. M., Morton, J. M. 2016


    Morbidly obese women are at increased risk for breast cancer, and the majority of surgical weight-loss patients are older than 40 years old.The purpose of the present study was to determine the technical and interpretive changes in mammography following bariatric surgery.Accredited Academic Hospital.Two breast-imaging radiologists reviewed screening mammograms performed on 10 morbidly obese women undergoing bariatric surgery both pre- and postoperatively. American College of Radiology Breast Imaging Reporting and Data System (ACR BI-RADS) density, imaging quality measurements, compression force, breast thickness, pectoral nipple line (PNL) length, and x-ray beam kilovoltage (kVp) and miliamperes per second (mAs) were recorded.The average patient age was 56 years old, with mean age at menarche of 13 years old; 70% of patients were postmenopausal (average age 49 years at menopause) and 50% had a family history of breast cancer. There was a significant reduction in both BMI (-13.2 kg/m(2), P<.01) and waist circumference (-32.0 cm, P<.01) following bariatric surgery. There was a significant reduction in breast thickness (-23.8 mm), reduction in PNL length (-1.9 cm), reduction in kVp (-1.2), and reduction in mAs (-16.7) even though there was no compression force change in pre- and postoperative mammograms detected. All breast densities were fatty or scattered though there were more scattered and fewer fatty images after surgery (P = .002).Morbidly obese women can undergo quality mammograms before and after bariatric surgery; however, weight loss after bariatric surgery leads to only slightly denser mammograms. Furthermore, weight loss reduces mammographic radiation doses.

  • Platinum(IV)-chlorotoxin (CTX) conjugates for targeting cancer cells JOURNAL OF INORGANIC BIOCHEMISTRY Graf, N., Mokhtari, T. E., Papayannopoulos, I. A., Lippard, S. J. 2012; 110: 58-63


    Cisplatin is one of the most widely used anticancer drugs. Its side effects, however, have motivated researchers to search for equally effective analogs that are better tolerated. Selectively targeting cancer tissue is one promising strategy. For this purpose, a platinum(IV) complex was conjugated to the cancer-targeting peptide chlorotoxin (CTX, TM601) in order to deliver cisplatin selectively to cancer cells. The 1:1 Pt-CTX conjugate was characterized by mass spectrometry and gel electrophoresis. Like most platinum(IV) derivatives, the cytotoxicity of the conjugate was lower in cell culture than that of cisplatin, but greater than those of its Pt(IV) precursor and CTX in several cancer cell lines.
