Evaluation of the prognostic utility of the combination of platelet count with mean platelet volume as a prognostic indicator in head and neck cancer.

The combination of platelet count to mean platelet volume (COP-MPV) has been recently reported as a prognostic indicator of oral cavity cancer and other cancer sites. The aim of the present study was to validate the utility of the COP-MPV as a prognostic indicator in all head and neck cancer (HNC) sites. The clinicopathological characteristics of the COP-MPV with HNC were also investigated. This is a retrospective cohort study that recruited consecutively treated patients at a tertiary level academic hospital. Clinicopathological characteristics were recorded, including the COP-MPV scores. Survival was analyzed using Kaplan-Meier analysis, as well as multivariate Cox Proportional Hazards regression. COP-MPV was not associated with the survival outcome in univariate or multivariate analysis. In the multivariate model, tumor differentiation, tumor stage, nodal stage, surgical margins and hemoglobin were revealed to be significantly associated with survival. The results demonstrated that the COP-MPV is not a suitable prognostic factor for HNC

Equine infectious keratitis in Finland : Associated microbial isolates and susceptibility profiles

Objective To retrospectively describe laboratory findings, treatment, and outcome associated with equine infectious keratitis in Finland. Animals and procedures Medical records of horses diagnosed with infectious keratitis in University of Helsinki Equine Hospital from January 2007 to June 2018 were reviewed. Results Forty-seven cases were included. Keratomycosis was diagnosed in 27 eyes and bacterial keratitis in 20 eyes. Aspergillus flavus was the most frequent fungal isolate (9/17, 53%), followed by Cylindrocarpon sp. (3/17, 18%) and Aspergillus fumigatus (2/17, 12%). Susceptibility was tested for 10/11 Aspergillus sp. isolates; all were susceptible to voriconazole while only two were susceptible to amphotericin B. Cylindrocarpon sp. isolates were resistant to both agents. Streptococcus equi subsp. zooepidemicus was the most frequent bacterial isolate (9/19, 47%), followed by other streptococci (4/19, 21%). All 13 Streptococcus sp. isolates were susceptible to penicillin, and all tested isolates (n = 11) were also susceptible to chloramphenicol. Mean duration of medical treatment was longer in fungal keratitis (38 days) than in bacterial keratitis (25 days) (P <.001). Twenty-six of the eyes underwent globe-sparing surgery in addition to medical therapy. Recovery was achieved in 66% (31/47) of all cases and in 59% (16/27) and 75% (15/20) (P = .264) of cases with keratomycosis and bacterial keratitis, respectively. Conclusions Although Aspergillus sp. and S zooepidemicus were the most frequently encountered isolates, cytology, culture, and susceptibility testing are essential to differentiate bacterial and fungal keratitis and guide the clinician to choose the most efficient treatment.Peer reviewe

A preliminary model of work during initial examination and treatment planning appointments

Objective This study's objective was to formally describe the work process for charting and treatment planning in general dental practice to inform the design of a new clinical computing environment.Methods Using a process called contextual inquiry, researchers observed 23 comprehensive examination and treatment planning sessions during 14 visits to 12 general US dental offices. For each visit, field notes were analysed and reformulated as formalised models. Subsequently, each model type was consolidated across all offices and visits. Interruptions to the workflow, called breakdowns, were identified.Results Clinical work during dental examination and treatment planning appointments is a highly collaborative activity involving dentists, hygienists and assistants. Personnel with multiple overlapping roles complete complex multi-step tasks supported by a large and varied collection of equipment, artifacts and technology. Most of the breakdowns were related to technology which interrupted the workflow, caused rework and increased the number of steps in work processes.Conclusion Current dental software could be significantly improved with regard to its support for communication and collaboration, workflow, information design and presentation, information content, and data entry

Systemic Anticancer Therapy and Thromboembolic Outcomes in Hospitalized Patients With Cancer and COVID-19

IMPORTANCE: Systematic data on the association between anticancer therapies and thromboembolic events (TEEs) in patients with COVID-19 are lacking. OBJECTIVE: To assess the association between anticancer therapy exposure within 3 months prior to COVID-19 and TEEs following COVID-19 diagnosis in patients with cancer. DESIGN, SETTING, AND PARTICIPANTS: This registry-based retrospective cohort study included patients who were hospitalized and had active cancer and laboratory-confirmed SARS-CoV-2 infection. Data were accrued from March 2020 to December 2021 and analyzed from December 2021 to October 2022. EXPOSURE: Treatments of interest (TOIs) (endocrine therapy, vascular endothelial growth factor inhibitors/tyrosine kinase inhibitors [VEGFis/TKIs], immunomodulators [IMiDs], immune checkpoint inhibitors [ICIs], chemotherapy) vs reference (no systemic therapy) in 3 months prior to COVID-19. MAIN OUTCOMES AND MEASURES: Main outcomes were (1) venous thromboembolism (VTE) and (2) arterial thromboembolism (ATE). Secondary outcome was severity of COVID-19 (rates of intensive care unit admission, mechanical ventilation, 30-day all-cause mortality following TEEs in TOI vs reference group) at 30-day follow-up. RESULTS: Of 4988 hospitalized patients with cancer (median [IQR] age, 69 [59-78] years; 2608 [52%] male), 1869 had received 1 or more TOIs. Incidence of VTE was higher in all TOI groups: endocrine therapy, 7%; VEGFis/TKIs, 10%; IMiDs, 8%; ICIs, 12%; and chemotherapy, 10%, compared with patients not receiving systemic therapies (6%). In multivariable log-binomial regression analyses, relative risk of VTE (adjusted risk ratio [aRR], 1.33; 95% CI, 1.04-1.69) but not ATE (aRR, 0.81; 95% CI, 0.56-1.16) was significantly higher in those exposed to all TOIs pooled together vs those with no exposure. Among individual drugs, ICIs were significantly associated with VTE (aRR, 1.45; 95% CI, 1.01-2.07). Also noted were significant associations between VTE and active and progressing cancer (aRR, 1.43; 95% CI, 1.01-2.03), history of VTE (aRR, 3.10; 95% CI, 2.38-4.04), and high-risk site of cancer (aRR, 1.42; 95% CI, 1.14-1.75). Black patients had a higher risk of TEEs (aRR, 1.24; 95% CI, 1.03-1.50) than White patients. Patients with TEEs had high intensive care unit admission (46%) and mechanical ventilation (31%) rates. Relative risk of death in patients with TEEs was higher in those exposed to TOIs vs not (aRR, 1.12; 95% CI, 0.91-1.38) and was significantly associated with poor performance status (aRR, 1.77; 95% CI, 1.30-2.40) and active/progressing cancer (aRR, 1.55; 95% CI, 1.13-2.13). CONCLUSIONS AND RELEVANCE: In this cohort study, relative risk of developing VTE was high among patients receiving TOIs and varied by the type of therapy, underlying risk factors, and demographics, such as race and ethnicity. These findings highlight the need for close monitoring and perhaps personalized thromboprophylaxis to prevent morbidity and mortality associated with COVID-19-related thromboembolism in patients with cancer

Clinical Characteristics, Racial Inequities, and Outcomes in Patients with Breast Cancer and COVID-19: A COVID-19 and Cancer Consortium (CCC19) Cohort Study

BACKGROUND: Limited information is available for patients with breast cancer (BC) and coronavirus disease 2019 (COVID-19), especially among underrepresented racial/ethnic populations. METHODS: This is a COVID-19 and Cancer Consortium (CCC19) registry-based retrospective cohort study of females with active or history of BC and laboratory-confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection diagnosed between March 2020 and June 2021 in the US. Primary outcome was COVID-19 severity measured on a five-level ordinal scale, including none of the following complications, hospitalization, intensive care unit admission, mechanical ventilation, and all-cause mortality. Multivariable ordinal logistic regression model identified characteristics associated with COVID-19 severity. RESULTS: 1383 female patient records with BC and COVID-19 were included in the analysis, the median age was 61 years, and median follow-up was 90 days. Multivariable analysis revealed higher odds of COVID-19 severity for older age (aOR per decade, 1.48 [95% CI, 1.32-1.67]); Black patients (aOR 1.74; 95 CI 1.24-2.45), Asian Americans and Pacific Islander patients (aOR 3.40; 95 CI 1.70-6.79) and Other (aOR 2.97; 95 CI 1.71-5.17) racial/ethnic groups; worse ECOG performance status (ECOG PS ≥2: aOR, 7.78 [95% CI, 4.83-12.5]); pre-existing cardiovascular (aOR, 2.26 [95% CI, 1.63-3.15])/pulmonary comorbidities (aOR, 1.65 [95% CI, 1.20-2.29]); diabetes mellitus (aOR, 2.25 [95% CI, 1.66-3.04]); and active and progressing cancer (aOR, 12.5 [95% CI, 6.89-22.6]). Hispanic ethnicity, timing, and type of anti-cancer therapy modalities were not significantly associated with worse COVID-19 outcomes. The total all-cause mortality and hospitalization rate for the entire cohort was 9% and 37%, respectively however, it varied according to the BC disease status. CONCLUSIONS: Using one of the largest registries on cancer and COVID-19, we identified patient and BC-related factors associated with worse COVID-19 outcomes. After adjusting for baseline characteristics, underrepresented racial/ethnic patients experienced worse outcomes compared to non-Hispanic White patients.

Evaluation of the prognostic utility of the hemoglobin-to-red cell distribution width ratio in head and neck cancer

© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Purpose: Hemoglobin is a known prognostic marker in many cancers, including head and neck cancer (HNC). There is some evidence that the red cell distribution width, which is an index of variation in size of red blood cells (RBCs), might be associated with prognosis as well. Recently, a novel prognostic biomarker has been reported—the ratio of the hemoglobin-to-red cell distribution width (Hb/RDW). Our objective was to evaluate the prognostic utility of the pretreatment Hb/RDW in HNC, controlled with known prognostic indices. Methods: Retrospective cohort study in a tertiary academic hospital setting. Patients diagnosed with HNC treated with curative-intent surgery were eligible. Metastatic disease was excluded. The variables collected were age, sex, BMI, alcohol/tobacco exposure, performance scores, ACE-27, tumor characteristics, adjuvant treatment, and lab values. The primary endpoints were event-free survival (EFS) and overall survival (OS). OS was defined as time from start of treatment to death from any cause, and EFS was defined as time from start of treatment to any progression, recurrence, or death from any cause. Univariate and multivariate survival analysis was performed on the primary endpoints. Results: A total of 205 patients were enrolled from 2010 to 2016. In multivariate analysis, the factors independently associated with EFS were BMI (p = 0.0364), advanced T stage (p = 0.001), and low Hb/RDW ratio (p = 0.017). The factors independently associated with OS were ECOG score (p = 0.042), advanced T stage (p \u3c 0.0001), positive nodes (p = 0.0195), and Hemoglobin (0.0134). Conclusion: A low Hb/RDW ratio was associated with poorer EFS (HR = 2.02, 95% CI 1.13–3.61, p = 0.017), but was not associated with OS. This is the first study reporting the prognostic utility of Hb:RDW in head and neck cancer

Supplementing Relaxation and Music for Pain After Surgery

BACKGROUND: Most postoperative patients have unrelieved pain despite the use of patient-controlled analgesia. Nurses need additional effective modalities. Relaxation and music (RM), in addition to analgesics, have been shown to reduce pain more than do analgesics alone. OBJECTIVES: The objectives of the study were to test an intervention of patient teaching for pain management (PT) and compare it with RM for immediate and general effects on postoperative pain. METHODS: Patients having abdominal surgery and receiving patient-controlled analgesia aged 18-75 years (n = 517) were randomized to four groups: PT, RM, a combination (PTRM), and a control. A 2 x 2 factorial design was used to assess PT-Effects and RM-Effects. Immediate effects on pain were measured on visual analogue sensation and distress scales before and after five 20-min tests in the first 2 days. Because participants also listened independently, general nonimmediate effects were examined at eight other times. RESULTS: Using multivariate analysis of covariance with contrasts and pretest control, immediate RM-Effects on pain were found at Day 1 a.m. (p \u3c .001), Day 1 p.m. (p = .04), and Day 2 a.m. (p = .04). No PT-Effects or nonimmediate RM-Effects were found. DISCUSSION: Patient teaching did not result in less pain and did not support the theoretical proposition that PT reduces pain. However, the immediate RM-Effects supported the proposition that nonpharmacological adjuvants to analgesics can ease pain without adding side effects
