Purpose Hematology/oncology clinical pharmacists' work activities have been described in previous literature, but time spent on pharmacist tasks has not been well characterized. Random work sampling (WS) is a form of activity assessment to determine the proportion of time spent in various types of work. Based on results from previous WS evaluations at University of Utah and its Huntsman Cancer Hospital, activities were changed to maximize time dedicated to clinical activities and pharmacists' benefit to providers and patients in both inpatient and ambulatory care settings. Therefore, updated random WS evaluations were completed during spring 2019 and fall 2020. Methods Personal digital assistant (PDA) devices were used to record hematology/oncology clinical pharmacists' onsite or remote location and work activity data. Data were collected 8 times per hour on weekdays, with a goal of 275 observations per pharmacist. Results were then classified as clinical, professional, or technical activities. Results In 2019, 9,079 observations were recorded by 31 onsite pharmacists. In 2020, 28 pharmacists recorded 8,803 observations (5,524 during onsite work and 3,279 during remote work). The overall distribution of pharmacists' work activities remained stable between 2019 and 2020, with 89% of activities classified as clinical or professional. Pharmacists spent a smaller proportion of time on in-person communication in 2020, balanced by increases in chart review and text-based communication. Onsite pharmacists reported a larger proportion of clinical activities, while remote pharmacists reported a larger proportion of professional activities. Conclusion Continued WS assessment of work activity patterns will allow identification of opportunities to streamline workflows, maximize pharmacist engagement in clinical activities, and development of remote work policy.

Objectives/Hypothesis: High rates of overall survival (OS) and laryngeal preservation were achieved in two sequential phase II clinical trials in patients with stage III/IV laryngeal squamous cell carcinoma (SCC). Patients were treated with chemoradiation after a >50% primary tumor response to one cycle of neoadjuvant chemotherapy (IC). We analyzed outcomes for T4 patients with cartilage invasion from both studies. Study Design: Retrospective. Methods: Records from 36 patients with T4 SCC of the larynx with cartilage invasion alone (n = 16) or cartilage invasion and extralaryngeal spread (n = 20) were retrospectively reviewed. All were treated with one cycle of cisplatin (100 mg/m2) [or carboplatin (AUC 6)] and 5-fluorouracil (1,000 mg/m2/d for 5 days) (P+5FU). Those achieving >50% response at the primary tumor received chemoradiation (70 Gy; 35 fractions with concurrent cisplatin-100 mg/m2 [carboplatin (AUC 6)] every 21 days for 3 cycles), followed by adjuvant P+5FU for complete histologic responders (CHR). Patients with <50% response after IC underwent total laryngectomy and postoperative radiation. Results: Twenty-nine of 36 patients (81%) had >50% response following IC. Of these, 27 received definitive chemoradiation, 23 (85%) obtained CHR, with 58% laryngeal preservation rate. The 3-year OS was 78%, and the disease-specific survival was 80% (median follow-up 69 months). Following chemoradiation, 8/11 (73%) patients with an intact larynx had >75% understandable speech, 6/36 (17%) were g-tube dependent and 6/36 (17%) were tracheostomy dependent. Conclusions: Our results suggest that chemo-selection is a feasible organ preservation alternative to total laryngectomy for patients with T4 laryngeal SCC with cartilage invasion.

Background A quasi-experimental retrospective study was undertaken to evaluate a new concept of free tissue volume restoration combined with bridging reconstruction plate (compartment approach) to reduce plate-related complication rates. Methods We evaluated 40 patients with large lateral mandible defects and associated complex soft tissue defects reconstructed with a revascularized soft tissue flap and titanium hollow screw reconstruction plates. A case-control comparison was performed based on reconstruction type: restoration of soft tissue defect (conventional approach—group 1) versus over-reconstruction of soft tissue defect (compartment approach—group 2). Results Plate exposure rate was 6 of 16 (38%) in group 1 versus 2 of 24 (8%) in group 2, and the difference was statistically significant (p = .04). The mean time to exposure was 10 months. Plate fracture rate was 6 of 23 (26.1%) in dentulous patients versus 1 of 17 (5.9%) in edentulous patients. Gastrostomy tube dependence was 6 of 16 (38%) in group 1 versus 6 of 24 (25%) in group 2. Conclusion The “compartment approach” reduces plate exposure rate and gastrostomy tube dependence. Revascularized osseocutaneous reconstruction is still required in dentulous patients. © 2008 Wiley Periodicals, Inc. Head Neck, 2008 [ABSTRACT FROM AUTHOR]

: PurposeWe sought to determine whether African American men diagnosed with prostate cancer in the prostate-specific antigen (PSA) era differed in initial presenting serum PSA levels (iPSA) compared to white men. Recent retrospective studies have demonstrated higher iPSA within the African American men than in white men at the time of diagnosis, suggestive of more advanced disease in African American men. Both biologic differences and/or sociologic factors have been postulated as explaining the noted differences in iPSA. We reviewed our institution''s PSA-era experience to determine any association between race and iPSA.: Methods and materialsBetween January 1990 and September 2001, 4519 patients representing a broad demographic sample were seen in the radiation oncology department of a university hospital or one of its four community affiliates. A total of 2332 eligible patients, with data on race, age, year of diagnosis, Gleason score, T stage, and iPSA, were analyzed. The patients were separated into the two following time periods for analysis, based on the new American Cancer Society screening guidelines: (1) 1991 to 1996 and (2) 1997 to 2001. The relationships between race and iPSA, T stage, Gleason score, and age are explored.: ResultsOf the 2332 patients analyzed, there were 1968 white men and 364 African American men. For the time period 1990 through 1996, the expected average (median) iPSA level was 10.5 (10.2) and 14.6 (15.8) for white men and African American men, respectively. For 1997 to 2001, the expected average iPSA level was 9.5 (8.4) and 10.8 (9.8), respectively. T stage distributions improved, independent of race, toward earlier stage at presentation. Gleason score distribution remained unchanged. African American men are 2.5–3.1 years younger than white men at diagnosis.: ConclusionAn overall decline in iPSA has occurred in both racial groups over time. More importantly, racial differences in iPSA among men diagnosed in the later time period (1997 to 2001) are less pronounced compared to men diagnosed in the earlier time period (1990 to 1996). This racial convergence in iPSA over time suggests improved penetrance of PSA screening in the African American population. Our findings also suggest that studies comparing racial differences in iPSA should consider time period of diagnosis and possible sociologic changes during that period (i.e., access to medical care, socioeconomic status, and educational level). The American Cancer Society guideline to begin screening African Americans at an earlier age is appropriate. [Copyright &y& Elsevier]

The deterioration from outdoor weathering of experimental wool fabrics differing in fiber fineness was measured by breaking strength, elongation at break, and crease recovery. With the amount of solar energy held approximately constant for each sampling period of each of the three consecutive sets of exposures, ambient temperature seemed to control the rate of deterioration.Differences in strength and elongation among the fabrics were non-significant. The fine wools recovered from creasing significantly more than the medium wool. [ABSTRACT FROM PUBLISHER]

Experimental cotton fabries made from four lots of Acala 1517C cotton fiber selected for strength and fineness were used for constructing 192 gingham dresses. One dress of each fabric was assigned to each of 48 wearers. A schedule for regular wear and care was established. Over a series of 16 wear periods, dresses were withdrawn in replicates of three according to a random sampling plan.The worn fabries were tested at each of the wear periods for qualities pertaining to durability and appearance. Regression equations were calculated and trends of change plotted. Properties of the fabries from the four fiber lots were compared. Fiber fine ness was of greater importance than strength in maintaining desirable wearing qualities of the fabries. [ABSTRACT FROM PUBLISHER]

Purpose: To determine the relationship between the radiation dose to the inner ear and long-term hearing loss. Methods and Materials: Eligible patients included those receiving curative radiotherapy (RT) for head-and-neck cancer. After enrollment, patients underwent three-dimensional conformal RT planning and delivery (180–200 cGy/fraction) appropriate for their disease site and stage. The inner ear was contoured on axial CT planning images. Dose-volume histograms, as well as the mean and maximal dose for each structure, were calculated. Patients underwent pure tone audiometry at baseline (before treatment) and 1, 6, 12, 24, and 36 months after RT. The threshold level (the greater the value, the more hearing loss) in decibels was recorded for 250, 500, 1000, 2000, 4000, and 8000 Hz. For patients receiving predominantly unilateral RT, the contralateral ear served as the de facto control. The differences in threshold level between the ipsilateral and contralateral ears were calculated, and the temporal pattern and dose-response relation of hearing loss were analyzed using statistical methods that take into account the correlation between two ears in the same subject and repeated, sequential measurements of each subject. Results: Of the 40 patients enrolled in this study, 35 qualified for analysis. Four patients who received concurrent chemotherapy and RT were analyzed separately. The 31 unilaterally treated patients received a median dose of 47.4 Gy (range, 14.1–68.8 Gy) to the ipsilateral inner ear and 4.2 Gy (range, 0.5–31.3 Gy) to the contralateral inner ear. Hearing loss was associated with the radiation dose received by the inner ear (loss of 210dB was observed in ears receiving ≥45 Gy) and was most appreciable in the higher frequencies (≥2000 Hz). For a 60-year-old patient with no previous hearing loss in either ear, after receiving 45 Gy, the ipsilateral ear, according to our clinical model, would have a 19.3-dB (95% confidence interval [CI], 15.5–23.0) and 5.4-dB (95% CI, 3.5–7.5) hearing decrement compared with the contralateral ear for 8000 Hz and 1000 Hz, respectively. Age and an initial hearing difference within an ear pair also affected hearing loss. The baseline hearing threshold was inversely related to radiation-induced hearing loss. The degree of hearing loss was dependent on the frequency tested, age, baseline hearing, and baseline difference in hearing between a patient’s two ears. Conclusion: High-frequency (≥2000 Hz) hearing acuity worsens significantly after RT in a dose-dependent fashion. A larger number of patients needs to be studied to validate these results. This knowledge can be applied to create guidelines regarding future dose limits to the auditory apparatus for patients undergoing head-and-neck RT. [Copyright &y& Elsevier]

Induction chemotherapy and concurrent chemoradiation for responders or immediate surgery for non-responders is an effective treatment strategy head and neck squamous cell carcinoma (HNSCC) of the larynx and oropharynx. Biomarkers that predict outcome would be valuable in selecting patients for therapy. In this study, the presence and titer of high risk human papilloma virus (HPV) and expression of epidermal growth factor receptor (EGFR) in pre-treatment biopsies, as well as smoking and gender were examined in oropharynx cancer patients enrolled in an organ sparing trial. HPV16 copy number was positively associated with response to therapy and with overall and disease specific survival, whereas EGFR expression, current or former smoking behavior, and female gender (in this cohort) were associated with poor response and poor survival in multivariate analysis. Smoking cessation and strategies to target EGFR may be useful adjuncts for therapy to improve outcome in the cases with the poorest biomarker profile. [ABSTRACT FROM AUTHOR]
