New occurrences of the bone-eating worm Osedax from Late Cretaceous marine reptiles and implications for its biogeography and diversification.

The bone-eating worm Osedax is a speciose and globally distributed clade, primarily found on whale carcasses in marine environments. The earliest fossil evidence for Osedax borings was previously described in plesiosaur and sea turtle bones from the mid-Cretaceous of the United Kingdom, representing the only unequivocal pre-Oligocene occurrences. Confirming through CT scanning, we present new evidence of Osedax borings in three plesiosaur specimens and, for the first time, identify borings in two mosasaur specimens. All specimens are from the Late Cretaceous: one from the Cenomanian of the United Kingdom, two from the Campanian of the southeastern United States, and two from the Maastrichtian of Belgium. This extends the geographic range of Osedax in the Cretaceous to both sides of the northern Atlantic Ocean. The bones contain five borehole morphotypes, potentially created by different species of Osedax, with the Cenomanian specimen containing three morphotypes within a single tooth. This combined evidence of heightened species diversity by the Cenomanian and broad geographic range by the Campanian potentially indicates an earlier origin and diversification for this clade than previously hypothesized. Preservational biases indicate that Osedax was probably even more widely distributed and speciose in the Cretaceous than apparent in the fossil record.

The Feasibility and Acceptability of a Diabetes Survival Skills Intervention for Persons Transitioning from Prison to the Community.

Community evidenced-based diabetes self-management education (DSME) models have not been examined for feasibility, acceptability, or effectiveness among persons transitioning from prison to the community to independent diabetes self-management (DSM). In a non-equivalent control group design with repeated measures, we examined the feasibility, acceptability, and preliminary effect of a 6-week, 1-h per week Diabetes Survival Skills (DSS) intervention on diabetes knowledge, distress, self-efficacy, and outcome expectancy for transitioning incarcerated males. Of the 92 participants (84% T2D, 83% using insulin, 40% Black, 20% White, 30% Latino, 66% high school or less, mean age 47.3 years, 84% length of incarceration ≤4 years ), 41 completed the study (22 control/19 intervention [TX]). One-way repeated measures ANOVAs revealed significant changes in diabetes knowledge within each group (C, p = .002; TX, p = .027) at all time points; however, a two-way repeated measures ANOVA showed no differences between groups. Additionally, both groups showed improvement in diabetes-related distress and outcome expectancy with the treatment group experiencing greater and sustained improvement at the 12-week time point. Analysis of focus group data (Krippendorf) revealed acceptance of and enthusiasm for the DSS training and low literacy education materials, the need for skill demonstration, and ongoing support throughout incarceration and before release. Our results highlight the complexity of working with incarcerated populations. After most of the sessions, we observed some information sharing between the intervention and the control groups on what they did in their respective sessions. Due to high attrition, the power to detect effects was limited. Yet, results suggest that the intervention is feasible and acceptable with an increased sample size and refined recruitment procedure. NCT05510531, 8/19/2022, retrospectively, registered.

Feasibility and safety of planned early discharge following laparotomy in gynecologic oncology with enhanced recovery protocol including opioid-sparing anesthesia.

Objective: This study aims to evaluate the feasibility and safety of planned postoperative day 1 discharge (PPOD1) among patients who undergo laparotomy (XL) in the department of gynecology oncology utilizing a modified enhanced recovery after surgery (ERAS) protocol including opioid-sparing anesthesia (OSA) and defined discharge criteria. Methods: Patients undergoing XL and minimally invasive surgery (MIS) were enrolled in this prospective, observational cohort study after the departmental implementation of a modified ERAS protocol. The primary outcome was quality of life (QoL) using SF36, PROMIS GI, and ICIQ-FLUTS at baseline and 2- and 6-week postoperative visits. Statistical significance was assessed using the two-tailed Student's t-test and non-parametric Mann-Whitney two-sample test. Results: Of the 141 subjects, no significant demographic differences were observed between the XL group and the MIS group. The majority of subjects, 84.7% (61), in the XL group had gynecologic malignancy [vs. MIS group; 21 (29.2%), p < 0.001]. All patients tolerated OSA. The XL group required higher intraoperative opioids [7.1 ± 9.2 morphine milligram equivalents (MME) vs. 3.9 ± 6.9 MME, p = 0.02] and longer surgical time (114.2 ± 41 min vs. 96.8 ± 32.1 min, p = 0.006). No significant difference was noted in the opioid requirements at the immediate postoperative phase and the rest of the postoperative day (POD) 0 or POD 1. In the XL group, 69 patients (73.6%) were successfully discharged home on POD1. There was no increase in the PROMIS score at 2 and 6 weeks compared to the preoperative phase. The readmission rates within 30 days after surgery (XL 4.2% vs. MIS 1.4%, p = 0.62), rates of surgical site infection (XL 0% vs. MIS 2.8%, p = 0.24), and mean number of post-discharge phone calls (0 vs. 0, p = 0.41) were comparable between the two groups. Although QoL scores were significantly lower than baseline in four of the nine QoL domains at 2 weeks post-laparotomy, all except physical health recovered by the 6-week time point. Conclusions: PPOD1 is a safe and feasible strategy for XL performed in the gynecologic oncology department. PPOD1 did not increase opioid requirements, readmission rates compared to MIS, and patient-reported constipation and nausea/vomiting compared to the preoperative phase.

Bilateral adnexal masses: A case report of acute myeloid leukemia presenting with myeloid sarcoma of the ovary and review of literature.

•We report a case of a patient with acute myeloid leukemia (AML) presenting as myeloid sarcoma.•This patient with bilateral adnexal masses was managed via total robotic hysterectomy with bilateral salpingo-oophorectomy.•There are a limited number of reports of bilateral ovarian occurrences that exist in the literature.•Myeloid sarcoma of the ovaries may present with vaginal bleeding to dysmenorrhea, dysuria, and palpable abdominal mass.

Health Literacy, Cognitive Impairment, and Diabetes Knowledge Among Incarcerated Persons Transitioning to the Community: Considerations for Intervention Development.

PURPOSE: The purpose of this study was to evaluate the relationships of health literacy (HL; Short Test of Functional Health Literacy), cognitive impairment (CI), and diabetes knowledge (DK) among incarcerated persons transitioning to the community. METHODS: Using preintervention data from a quasi-experimental nonequivalent control group study evaluating the feasibility of a six-session literacy-tailored Diabetes Survival Skills intervention for incarcerated men transitioning to the community, we conducted correlational analyses among the Short Test of Functional Health Literacy, Montreal Cognitive Assessment, and Spoken Knowledge in Low Literacy in Diabetes Scale using the SPSS PROCESS macro and bias-corrected bootstrapping to test the meditational hypothesis: HL mediates the relationship between CI and DK. RESULTS: Participants ( N = 73) were incarcerated for 1-30 years with a mean age of 47 (9.9) years, 40% Black, 19% White, and 30% Hispanic, with 78% having high school/GED or less education. Most (70%) screened positive for CI and had low DK, and 20% had marginal or inadequate HL. HL, CI, and DK were positively associated with each other. Controlling for race, age, and group (control/experimental), cognitive function had a significant direct effect on HL ( b = 0.866, p = 0.0003) but not on DK ( b = 0.119, p = 0.076). Results indicated a significant indirect effect of cognitive functioning on DK via HL, 95% confidence interval [0.300, 0.1882]. CONCLUSION: Intervention approaches aimed at increasing HL or tailored to low HL in the presence of CI may be effective in increasing DK in this population. IMPLICATIONS: Given the low risk to high benefit of implementing literacy-tailored approaches to persons in prison and the population demographics from studies supporting a high degree of CI, nurses should consider implementing literacy-tailored approaches and screening for CI before participation in all educational programs.

Dietary niche partitioning in Early Jurassic ichthyosaurs from Strawberry Bank.

Jurassic ichthyosaurs dominated upper trophic levels of marine ecosystems. Many species coexisted alongside each another, and it is uncertain whether they competed for the same array of food or divided dietary resources, each specializing in different kinds of prey. Here, we test whether feeding differences existed between species, applying finite element analysis to ichthyosaurs for the first time. We examine two juvenile ichthyosaur specimens, referred to Hauffiopteryx typicus and Stenopterygius triscissus, from the Strawberry Bank Lagerstätte, a shallow marine environment from the Early Jurassic of southern England (Toarcian, ~183 Ma). Snout and cranial robusticity differ between the species, with S. triscissus having a more robust snout and cranium and specializing in slow biting of hard prey, and H. typicus with its slender snout specializing in fast, but weaker bites on fast-moving, but soft prey. The two species did not differ in muscle forces, but stress distributions varied in the nasal area, reflecting differences when biting at different points along the tooth row: the more robustly snouted Stenopterygius resisted increases or shifts in stress distribution when the bite point was shifted from the posterior to the mid-point of the tooth row, but the slender-snouted Hauffiopteryx showed shifts and increases in stress distributions between these two bite points. The differences in cranial morphology, dentition and inferred stresses between the two species suggest adaptations for dietary niche partitioning.

Kidney thrombotic microangiopathy in lupus nephritis: Impact on treatment and prognosis.

INTRODUCTION: Lupus nephritis (LN) may present with thrombotic microangiopathy (TMA) on kidney biopsy, the impact of which on outcomes is unclear. This study examined the prognostic importance of LN with TMA on kidney biopsy, including response to therapy and long-term outcomes. METHODS: We conducted a single-center, retrospective study of all cases of LN with concomitant TMA on kidney biopsy in the Glomerular Disease Collaborative Network database. Controls were individuals with LN without TMA matched to cases based on demographic and clinical variables. Outcomes were remission at 6- and 12-months, end-stage kidney disease (ESKD) and death. Logistic regression and Cox proportional hazards models were used to ascertain the risks for outcomes, with adjustment for serum creatinine and proteinuria. RESULTS: There were 17 cases and 28 controls. Cases had higher creatinine, higher proteinuria and greater chronicity on biopsy at baseline compared to controls. The rates of remission at 6-months and 12-months were similar between cases and controls (6-months 53.9% vs 46.4%, adjusted OR 2.54, 95% CI 0.48, 13.37; 12-months 53.9% vs 50.0%, adjusted OR 2.95, 95% CI 0.44, 19.78). Cases were at greater risk for ESKD in univariate analysis (HR 3.77; 95% CI 1.24, 11.41) but not when adjusting for serum creatinine and proteinuria (HR 2.20; 95% CI 0.63, 7.71). There was no significant difference in the risk of death between cases and controls. CONCLUSION: Lupus nephritis with renal TMA likely responds to therapy similarly to those without TMA; risk for ESKD is not significantly increased, although the influence of renal function and proteinuria in larger samples is needed.

Therapeutic plasma exchange in the intensive care unit and with the critically ill, a focus on clinical nursing considerations.

Therapeutic plasma exchange (TPE) is a blood purification technique removing antibodies and plasma proteins to modulate disease and promote recovery. The procedure has different methods, using a membrane or plasma separator with many elements similar to continuous renal replacement therapy (CCRT) in the Intensive Care Unit (ICU). These nursing knowledge and skill sets apply where ICU nurses are providing TPE with increasing need. However, different care models are also in place where TPE is the responsibility of apheresis and nephrology teams visiting the ICU. The plasma replacement volume and prescribing is aligned with published guidelines but is variable when critical illness overlays the primary indication for TPE. There are some important considerations for TPE with respect to anticoagulation, machine settings, prescribing, and associated nursing management. TPE can be performed concurrent with CRRT in acute situations using Y-piece and valve connectors and is a new and recent advanced blood purification for the ICU.

Trends in Incidence and Mortality Rates of Uterine Cancer in Kentucky.

OBJECTIVES: The objective of this analysis was to gauge how the incidence and mortality of uterine cancer in Kentucky have changed from 1995 through 2017. An assessment of the trends in incidence and mortality across different geographic areas and between different races was also performed. METHODS: Age-adjusted annual incidence and mortality rates for uterine cancer were obtained from the Kentucky Cancer Registry. A meta-regression framework was used to assess changes in incidence and mortality rates during the time frame and to determine differences in these rates between rural versus urban counties, Appalachian versus non-Appalachian counties, and Black versus White women. RESULTS: The incidence of uterine cancer has significantly increased throughout the state of Kentucky since 1995. Uterine cancer incidence was 10% and 22% higher in rural and Appalachian counties, respectively, compared with urban and non-Appalachian counties (P < 0.0001) from 1995 through 2017. In contrast, urban and non-Appalachian women had higher or equivalent age-adjusted mortality from uterine cancer, compared with rural and Appalachian women, respectively. The incidence of uterine cancer was significantly higher in White women compared with Black women from 1995 through 2006, but since 2007, there has been no significant difference in uterine cancer incidence based on race. Black women had higher age-adjusted mortality than White women throughout the entire time period examined. CONCLUSIONS: The incidence of uterine cancer is higher in rural and Appalachian Kentucky, without a corresponding geographic trend in mortality. Uterine cancer mortality is significantly higher in Black women.

Development of an Advance Care Planning Protocol in a Cystic Fibrosis Outpatient Clinic.

Background: Advance care planning (ACP) is recommended for all patients with cystic fibrosis (CF), yet clear implementation guidelines do not exist. Methods: The University of North Carolina Adult CF Care Team developed a process to implement semistructured multidisciplinary outpatient ACP meetings as routine care for patients with CF. Premeeting and post-meeting surveys were used to elicit patients' attitudes toward ACP. Results: Twenty-seven adults with CF completed a face-to-face ACP meeting, and 13 completed both surveys. Following the multidisciplinary ACP meeting, overall scores for understanding of ACP topics improved by 4.5 points (p = 0.003). Conclusion: We successfully implemented sustainable ACP meetings for adults with CF and found increased comfort with ACP and documentation of wishes after ACP meetings. It is important for CF care providers to meet the needs of this patient population by ensuring that ACP is in place before crisis situations.

Vaginal cuff brachytherapy: do we need to treat to more than a two-centimeter active length?

PURPOSE: American Brachytherapy Society (ABS) guidelines recommend using a 3-5 cm active length (AL) when treating vaginal cuff (VC) in adjuvant setting of endometrial cancer (EC). The purpose of this study was to evaluate local control and toxicity, using an AL of 1 or 2 cm and immobilization with a traditional table-mounted (stand) or patient-mounted (suspenders) device. MATERIAL AND METHODS: Between 2005 and 2019, 247 patients with EC were treated with adjuvant high-dose-rate vaginal cuff (HDR-VC) brachytherapy with or without external beam radiation (EBRT). Treatment was prescribed to a 0.5 cm depth, with an AL of 1 or 2 cm, using stand or suspenders. VC boost after EBRT was typically administered with 2 fractions of 5.5 Gy, while VC brachytherapy alone was typically applied with 3 fractions of 7 Gy or 5 fractions of 5.5 Gy. RESULTS: The combination of suspender immobilization and an AL of 2 cm (n = 126, 51%) resulted in 5-year local control of 100%. An AL of 2 cm compared to 1 cm correlated with better local control (99.1% vs. 88.5%, p = 0.0479). Regarding immobilization, suspenders correlated with improved local control compared to stand (100% vs. 86.7%, p = 0.0038). Immobilization technique was significantly correlated with AL (p < 0.0001). Only 5 (2.0%) patients experienced grade ≥ 3 toxicity, all of whom received EBRT. CONCLUSIONS: In the present series, an AL of 2 cm provided excellent local control, while 1 cm was inadequate. Suspender immobilization was a practical alternative to stand immobilization in HDR brachytherapy of the vaginal cuff.

Impact of age, comorbidity, and treatment characteristics on survival in older women with advanced high grade epithelial ovarian cancer.

OBJECTIVES: Older women have a worse prognosis with advanced epithelial ovarian cancer (EOC) and comorbidities likely contribute to poor outcomes. We sought to identify comorbid conditions and treatment-related factors in older women. METHODS: A retrospective chart review identified 351 patients who underwent cytoreductive surgery (CRS). 100/351 (28.5%) were ≥ 70 years old. Demographic and clinicopathologic information was collected. Crude progression-free (PFS) and overall survival (OS) estimates were calculated using Kaplan-Meier method. Cox proportional hazards regression model was used to estimate hazard ratios and adjustments for confounders. RESULTS: Study subjects ≥70 years old had significantly: higher Cumulative Illness Rating Scale-Geriatric (CIRS-G) score (5.9 vs 4.3; p = 0.0001), less completion of adjuvant chemotherapy (24% vs 15.1%; p = 0.049), less intraperitoneal (IP) therapy (18.2% vs 35.5%; p = 0.002), less clinical trial participation (16% vs 26.3%; p = 0.040), decreased platinum sensitivity (60% vs 73.7%; p = 0.012) and lacked BRCA mutations (0% vs 12%; p = 0.0006). They were less likely to have optimal CRS (75% vs 86.9%; p = 0.007) with same surgical complexity (p = 0.89). Patients ≥70 had significantly worse PFS and OS. In a multivariate analysis, better OS was associated with younger age (<70 years old), any IP therapy, completion of adjuvant chemotherapy, and platinum sensitivity. CONCLUSION: The older cohort had worse CIRS-G scores (5.9 vs 4.3; p = 0.0001), but no strong associations between comorbidities and treatment characteristics, but less optimal CRS rates (75% vs 86.9%; p = 0.007) with similar surgical complexity and less platinum sensitivity. Our results show comorbid conditions in older patients with advanced EOC may have less impact than tumor biology.

Role of adjuvant chemotherapy in patients with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma treated with surgery and post-operative radiotherapy.

BACKGROUND: The optimal treatment of patients with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma remains unknown. OBJECTIVE: To compare overall survival following treatment with a hysterectomy and adjuvant radiotherapy with or without chemotherapy in this group of patients. METHODS: Patients diagnosed between January 2004 and January 2016 with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma treated with hysterectomy and postoperative radiotherapy with or without adjuvant concurrent chemotherapy were identified in the National Cancer Database. Overall survival was assessed with Kaplan-Meier curves. A Cox model was constructed to evaluate survival after controlling for confounding variables. A logistic regression model was used to reveal predictors of chemotherapy use. RESULTS: A total of 2173 patients were included. The receipt of chemotherapy was associated with an increased 5-year overall survival from 67.6% to 75.6% (p=0.0313). This association trended toward statistical significance on multivariate analysis (adjusted HR (aHR) 0.80; 95% CI 0.63 to 1.01; p=0.0653). Other factors associated with improved survival were undergoing a lymphadenectomy, absence of lymphovascular space invasion, younger age, smaller tumor size, non-black race, and absence of comorbidities. Patients who underwent brachytherapy, had lymphovascular space invasion, were younger, were diagnosed in the more recent years, and were treated in higher volume centers were more likely to receive adjuvant chemotherapy. CONCLUSION: Adjuvant chemotherapy and radiation therapy were associated with an increase in survival in patients with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma compared with those treated with adjuvant radiotherapy alone.

Retrospective Review for Medication Dose Errors in Pediatric Emergency Department Medication Orders That Bypassed Pharmacist Review.

OBJECTIVE: To identify and evaluate dose errors on medication orders that bypassed pharmacist verification in a pediatric emergency department (PED). METHODS: Descriptive, retrospective study about dose errors in an academic PED over 1 year. A report of automatically verified orders (those that bypassed pharmacist verification) was obtained from the electronic medical record. Potential medication dose errors were defined as those greater than 20% above or below standard dose ranges by age or weight. A retrospective chart review was performed for all identified dose errors. For orders deemed erroneous, additional metrics collected included order time of day and day of week and provider training level. RESULTS: A total of 46,185 medication orders were placed; 32,928 (71%) bypassed pharmacist review. Altogether, 676 orders (2%) were outside standard dose ranges. Ondansetron represented 569 of the 676 orders; most were doses rounded down to 4 mg and technically qualifying as underdoses, but were attributed to practice variance and not further analyzed. The number of orders deemed potentially erroneous was 107: most were wrong dose (75 overdose and 21 underdose), 5 were wrong patient, and 6 were wrong formulation. Ibuprofen, benzodiazepine, and corticosteroid orders had the most errors. No errors resulted in identifiable harm to the patient: 49 were near misses, and 47 reached the patient with no evident harm. CONCLUSIONS: The overall number of dose errors in autoverified orders was low. Certain medications or ordering modalities may be targeted to enhance patient safety and satisfaction.

The impact of brachytherapy boost and radiotherapy treatment duration on survival in patients with vaginal cancer treated with definitive chemoradiation.

PURPOSE: Vaginal cancer is a rare tumor that is optimally treated with a combination of chemotherapy (CHT) and radiation therapy. Because of the rarity of this cancer, the benefit of a brachytherapy boost (BT) and the relevance of radiotherapy time to treatment completion (TTC) are unclear. METHODS: Patients diagnosed between 2004 and 2015 with non-metastatic vaginal cancer treated with definitive CHT and external beam radiotherapy with or without BT but with no surgery were identified in the National Cancer Database. Overall survival (OS) was assessed with Kaplan-Meier curves, and differences between groups were compared with the log-rank test. A Cox model was constructed to evaluate survival after controlling for confounders. A Cox model using a penalized spline function was constructed to evaluate how the length of radiation therapy correlated with OS among patients receiving BT. RESULTS: A total of 1094 patients who met the inclusion criteria were identified. The utilization of BT was associated with improved 5-year OS (62.9% vs. 49.3%, p = 0.0126) on propensity score-weighted analyses. TTC of 63 days or less was associated with improved 5-year OS (67.8% vs. 54.5%, p = 0.0031) in patients who underwent BT. Other factors associated with improved OS in patients who received CHT, external beam radiotherapy, and BT were younger age, absent comorbidity score, and negative lymph nodes. CONCLUSIONS: A brachytherapy boost and shorter TTC were associated with a survival benefit in a cohort of patients with non-metastatic vaginal cancer treated with definitive chemoradiotherapy.

Topical rapamycin for acanthosis nigricans in the Fitzpatrick IV/V adolescent population.

Dermatologically, FGFR3 mutations can lead to acanthosis nigricans (AN), epidermal nevi, and seborrheic keratosis. A recent case report found that topical rapamycin (sirolimus) can improve FGFR3-induced epidermal nevi with AN features in children, specifically with Fitzpatrick skin type (FST) I/II, and we would like to expand these findings to skin plaques with extensive AN-like features in the FST IV/V adolescent population. An 18-year-old female with FST IV/V and FGFR3-induced hypochondroplasia presented to our clinic with extensive AN-like plaques. Significant improvement with lightening and thinning of the plaques was observed after applying 1% topical rapamycin cream twice daily. Topical rapamycin should be considered as a treatment option for AN, particularly in FST IV/V adolescents with FGFR3-induced AN.

Dual antibiotic prevention bundle is associated with decreased surgical site infections.

BACKGROUND: Gynecologic oncology surgery is associated with a wide variation in surgical site infection risk. The optimal method for infection prevention in this heterogeneous population remains uncertain. STUDY DESIGN: A retrospective cohort study was performed to compare surgical site infection rates for patients undergoing hysterectomy over a 1-year period surrounding the implementation of an institutional infection prevention bundle. The bundle comprised pre-operative, intra-operative, and post-operative interventions including a dual-agent antibiotic surgical prophylaxis with cefazolin and metronidazole. Cohorts consisted of patients undergoing surgery during the 6 months prior to this intervention (pre-bundle) versus those undergoing surgery during the 6 months following the intervention (post-bundle). Secondary outcomes included length of stay, readmission rates, compliance measures, and infection microbiology. Data were compared with pre-specified one-sided exact test, Chi-square test, Fisher's exact test, or Kruskal-Wallis test as appropriate. RESULTS: A total of 358 patients were included (178 PRE, 180 POST). Median age was 58 (range 23-90) years. The post-bundle cohort had a 58% reduction in surgical site infection rate, 3.3% POST vs 7.9% PRE (-4.5%, 95% CI -9.3% to -0.2%, p=0.049) as well as reductions in organ space infection, 0.6% POST vs 4.5% PRE (-3.9%, 95% CI -7.2% to -0.7%, p=0.019), and readmission rates, 2.2% POST vs 6.7% PRE (-4.5%, 95% CI -8.7% to -0.2%, p=0.04). Gram-positive, Gram-negative, and anaerobic bacteria were all prevalent in surgical site infection cultures. There were no monomicrobial infections in post-cohort cultures (0% POST vs 58% PRE, p=0.04). No infections contained methicillin-resistant Staphylococcus aureus. CONCLUSION: Implementation of a dual antibiotic infection prevention bundle was associated with a 58% reduction in surgical site infection rate after hysterectomy in a surgically diverse gynecologic oncology practice.

Mitigating the impact of COVID-19 on oncology: Clinical and operational lessons from a prospective radiation oncology cohort tested for COVID-19.

BACKGROUND AND PURPOSE: The COVID-19 pandemic warrants operational initiatives to minimize transmission, particularly among cancer patients who are thought to be at high-risk. Within our department, a multidisciplinary tracer team prospectively monitored all patients under investigation, tracking their test status, treatment delays, clinical outcomes, employee exposures, and quarantines. MATERIALS AND METHODS: Prospective cohort tested for SARS-COV-2 infection over 35 consecutive days of the early pandemic (03/19/2020-04/22/2020). RESULTS: A total of 121 Radiation Oncology patients underwent RT-PCR testing during this timeframe. Of the 7 (6%) confirmed-positive cases, 6 patients were admitted (4 warranting intensive care), and 2 died from acute respiratory distress syndrome. Radiotherapy was deferred or interrupted for 40 patients awaiting testing. As the median turnaround time for RT-PCR testing decreased from 1.5 (IQR: 1-4) to ≤1-day (P < 0.001), the median treatment delay also decreased from 3.5 (IQR: 1.75-5) to 1 business day (IQR: 1-2) [P < 0.001]. Each patient was an exposure risk to a median of 5 employees (IQR: 3-6.5) through prolonged close contact. During this timeframe, 39 care-team members were quarantined for a median of 3 days (IQR: 2-11), with a peak of 17 employees simultaneously quarantined. Following implementation of a "dual PPE policy," newly quarantined employees decreased from 2.9 to 0.5 per day. CONCLUSION: The severe adverse events noted among these confirmed-positive cases support the notion that cancer patients are vulnerable to COVID-19. Active tracking, rapid diagnosis, and aggressive source control can mitigate the adverse effects on treatment delays, workforce incapacitation, and ideally outcomes.

Cervical cancer incidence and mortality rates in Kentucky.

OBJECTIVES: The goal of this study was to assess how the incidence and mortality of cervical cancer in Kentucky has changed from 1995 through 2017. Additionally, trends in incidence and mortality across different geographic areas and between different races were evaluated. METHODS: Age-adjusted annual incidence and mortality rates for cervical cancer were collected from the Kentucky Cancer Registry (KCR). A quadratic fit model was used to evaluate changes in the incidence and mortality over time and to compare differences in cervical cancer incidence and mortality by: 1) rural versus urban counties, 2) Appalachian versus non-Appalachian counties, and 3) black versus white women. RESULTS: Overall, the incidence of cervical cancer has significantly decreased throughout Kentucky since 1995. When comparing different geographic regions, the incidence was 14% and 23% higher in rural and Appalachian counties, respectively, compared to urban and non-Appalachian counties (p < 0.0001) throughout the study period. The incidence of cervical cancer was significantly higher in black women compared to white women from 1995 through 2007, but since 2008 there has been no significant difference in cervical cancer incidence based on race. Similar to incidence rates, mortality from cervical cancer was 29% higher in Appalachia (p = 0.0004) throughout the studied time period. Black women had higher age-adjusted mortality than white women until 2012, but since that time there has not been a significant difference in cervical cancer mortality based on race. CONCLUSIONS: Women residing in rural and Appalachian Kentucky have higher cervical cancer incidence and mortality rates.
