Effect of esophageal cancer screening on mortality among patients with oral cancer and second primary esophageal cancer in Taiwan.

OBJECTIVE: Oral and esophageal cancer are the fourth and fifth leading causes of cancer deaths among men in Taiwan. Despite a good prognosis for oral cavity cancer patients, survival is worse for those who develop second primary esophageal cancer. There remains no consensus regarding early prevention of potential second primary esophageal cancer in patients with oral cavity cancer. Our study aimed to compare 5-year mortality between endoscopically screened and non-screened patients with oral cavity cancer and second primary esophageal cancer. MATERIALS AND METHODS: This study identified patients with incident oral cavity cancer and second primary esophageal cancer during 2004 and 2013 using the Taiwan Cancer Registry and National Health Insurance Research Database. We compared 5-year mortality from the second primary esophageal cancer diagnosis date between screened and non-screened groups of patients with oral cavity cancer and second primary esophageal cancer. RESULTS: A total of 217 screened and 305 non-screened oral cavity cancer patients with second primary esophageal cancer were studied. Endoscopic screening significantly improved early detection of second primary esophageal cancer (adjusted odds ratio: 0.34, 95 % confidence interval [CI]: 0.23-0.49) and reduced all-cause mortality (adjusted hazard ratio: 0.80; 95 % CI: 0.66-0.98). CONCLUSIONS: Oral cavity cancer patients with second primary esophageal cancer may have worse overall survival than those without. Early detection of second primary esophageal cancer is a crucial mediator between endoscopic screening and mortality. Endoscopic screening after the diagnosis of incident oral cavity cancer significantly increased early detection and reduced all-cause mortality.

Serious Illness Communication Training Among Radiation Oncology Residents.

PURPOSE: Education and specific training on serious illness communication skills for radiation oncology residents is lacking. The Accreditation Council for Graduate Medical Education requires radiation oncology residents to demonstrate interpersonal and communication skills; however, implementing specific training to address this poses an ongoing challenge. This study assesses the feasibility and effectiveness of a radiation oncology specific serious illness communication curriculum at a single radiation oncology residency program. METHODS AND MATERIALS: The primary objectives were to assess observable communication skills among radiation oncology residents and their perceived level of preparedness and comfort with patient encounters surrounding serious illness. Each resident participated in a baseline simulated patient encounter. Two virtual half-day experience-based learning sessions led by faculty experts trained in teaching serious illness communication were held. The training consisted of brief didactic teaching, with the emphasis on small group guided practice with simulated patients in scenarios specific to radiation oncology. Each resident participated in a postcourse simulated patient encounter. Three blinded faculty trained in serious illness communication completed objective assessments of observable communication skills to compare pre- and postcourse performance. RESULTS: A t test based on validated assessments reviewed by blinded faculty demonstrated significant improvement in overall observable communication skills among radiation oncology residents in the postcourse encounter compared with the precourse encounter (P = .0067). Overall, 8 of 9 (89%) residents felt more comfortable and prepared with radiation oncology-specific serious illness communication after the course compared with prior. The simulated patients rated the overall average resident performance higher on the postcourse assessment (Likert 4.89/5) compared with the precourse assessment (Likert 4.09/5), which trended toward a significant improvement (P = .0515). CONCLUSIONS: Radiation oncology residents had a significant improvement in observable communication skills after participating in an experience-based training curriculum. This course can serve as an adaptable model that may be implemented by other radiation oncology residency programs.

Comparative effectiveness and stage-shift effect of endoscopic exam among newly diagnosed oral cancer patients with different stages in Taiwan.

BACKGROUND: Patients with oral cancer are at higher risk of developing second primary esophageal cancer (SPEC) and the consensus for screening strategies remains unclear. This study aimed to examine comparative effectiveness and the stage-shift effect of endoscopic exam among patients with oral cancer. METHOD: A population-based longitudinal retrospective observational matched case and control cohort study with at least 5 years follow-up was conducted. We identified 45 457 newly diagnosed patients with oral cancer, 2004-2013, and the eligible patient with oral cancer was 39 401. Propensity score matching was used to match comparable groups, and the two groups (screening vs. nonscreening) was 5941, individually. The study primary endpoints were to compare detection of incident SPEC and the stage-shift effect of endoscopic screening between screened and nonscreened incident oral cancer patients. Cox proportional hazard and competing risk models were analyzed. Statistical analyses were conducted in 2020-2021. RESULT: Detection of incident SPEC in the screened group was significantly higher than in the nonscreened group (hazard ratio: 2.92, 95% confidence interval [CI]: 2.29-3.72). The stage-shift effect from endoscopic screening was found overall in patients with oral cancer (odds ratio [OR]: 0.39, 95%CI: 0.21-0.70), in particular in advanced-stage patients (OR: 0.25, 95%CI: 0.11-0.61), but not in early-stage patients (OR: 0.60, 95%CI: 0.26-1.40). CONCLUSION: This study confirmed that endoscopic screening achieved early detection of SPEC among patients with oral cancer. To improve the screening stage-shift effect, patients with oral cancer are encouraged to undergo routine endoscopic screening.

Mortality Risks for Dialysis Patients: A Nationwide Population-Based Study.

OBJECTIVE: Several studies have demonstrated increased postoperative mortality rates in patients on chronic hemodialysis compared with non-dialyzed patients. However, limited studies have examined factors that may contribute to postoperative mortality. METHODS: In this retrospective cohort study, data were collected from 9,140 dialysis and 45,725 non-dialysis patients undergoing surgery between 2007 to 2009 from Taiwan's National Health Insurance Registry Database. Patient demographics, comorbidities, and anesthesia duration were used to compare 30-day postoperative mortality differences in dialysis patients. RESULTS: Dialysis patients undergoing first-time surgery were significantly older, more likely male, and possessed more comorbidities. Overall, dialysis patients had significantly higher all-cause postoperative mortality (odds ratio, 15.005; 95% confidence interval, 11.917-18.893). Gender (hazard ratio [HR], 0.762), age (HR, 1.012), longer duration of inhalation general anesthesia (HR, 1.113), and comorbidities of hypertension (HR, 0.759), diabetes (HR, 1.339), congestive heart failure (HR, 1.232), coronary artery disease (HR, 1.326), cerebral vascular accident (HR, 1.312), intracranial hemorrhage (HR, 6.765), gastrointestinal bleeding (HR, 1.396), and liver cirrhosis (HR, 2.027), independently increased postoperative mortality risk in dialysis patients. Of the comorbidities, intracranial hemorrhage posed the greatest risk. CONCLUSION: Patient demographics, anesthesia factors, and comorbidities help dialysis patients understand their postoperative mortality. These potential risk factors also inform anesthesiologists and surgeons weight perioperative conditions in dialysis patients before surgery.

Transfusion practices at end of life for hematopoietic stem cell transplant patients.

PURPOSE: Limited data exist regarding transfusion practices at end of life (EOL) for hematopoietic stem cell transplant (HSCT) patients. The purpose of this study was to examine red blood cell (RBC) and platelet transfusion practices in HSCT patients who enrolled or did not enroll in hospice. METHODS: This was a single-center, retrospective chart review in deceased HSCT patients. The primary objective was to determine the mean difference between the last transfusion and death in HSCT patients (n = 116) who enrolled or did not enroll in hospice. RESULTS: Sixteen (14%) and 100 (86%) patients were enrolled in hospice and not enrolled in hospice, respectively. Hospice patients observed a larger mean difference between death and last transfusion (45.9 ± 66.7 vs. 14.6 ± 48.1 days, p < 0.0001). A higher amount of platelet, but not RBC, transfusions occurred in patients not enrolled in hospice (p = 0.04). The last transfusion that occurred more than 96 h before death was observed in 12 (75%) and 22 (22%) in hospice and non-hospice patients, respectively. For HSCT patients not enrolled in hospice, 17 patients received a transfusion on the same day of death and 31 patients received the last transfusion 24 h before death. CONCLUSIONS: Blood transfusion practices differed in HSCT patients enrolled and not enrolled in hospice. For most patients not enrolled in hospice, the last transfusion occurred 24 h before death. Future efforts should explore if limited access to blood products is a barrier to hospice enrollment for HSCT patients.

Advance Care Planning and Palliative Care Integration for Patients Undergoing Hematopoietic Stem-Cell Transplantation.

PURPOSE: Advance care planning (ACP) in hematopoietic stem-cell transplantation (HSCT) is challenging, given the potential for cure despite increased morbidity and mortality risk.The aim of this study was to evaluate ACP and palliative care (PC) integration for patients who underwent HSCT. METHODS: A retrospective analysis was conducted and data were extracted from electronic medical records of patients who underwent HSCT between January 2011 and December 2015. Patients who received more than one transplant and who were younger than 18 years of age were excluded. The primary objective was to determine the setting and specialty of the clinician who documented the initial and final code status. Secondary objectives included evaluation of advance directive and/or completion of the Physician Orders for Life-Sustaining Treatment form, PC consultation, hospice enrollment, and location of death. RESULTS: The study sample comprised 39% (n = 235) allogeneic and 61% (n = 367) autologous HSCTs. All patients except one (n = 601) had code status documentation, and 99.2% (n = 596) were initially documented as full code. Initial and final code status documentation in the outpatient setting was 3% (n = 17) and 24% (n = 143), respectively. PC consultation occurred for 19% (n = 114) of HSCT patients, with 83% (n = 95) occurring in the hospital. Allogeneic transplant type and age were significantly associated with greater rates of advance directive and/or Physician Orders for Life-Sustaining Treatment completion. Most patients (85%, n = 99) died in the hospital, and few were enrolled in hospice (15%, n = 17). CONCLUSION: To our knowledge, this is the largest single-center study of ACP and PC integration for patients who underwent HSCT. Code status documentation in the outpatient setting was low, as well as utilization of PC and hospice services.

Cofactors of LIM Domains Associate with Estrogen Receptor α to Regulate the Expression of Noncoding RNA H19 and Corneal Epithelial Progenitor Cell Function.

Cofactors of LIM domain proteins, CLIM1 and CLIM2, are widely expressed transcriptional cofactors that are recruited to gene regulatory regions by DNA-binding proteins, including LIM domain transcription factors. In the cornea, epithelium-specific expression of a dominant negative (DN) CLIM under the keratin 14 (K14) promoter causes blistering, wounding, inflammation, epithelial hyperplasia, and neovascularization followed by epithelial thinning and subsequent epidermal-like differentiation of the corneal epithelium. The defects in corneal epithelial differentiation and cell fate determination suggest that CLIM may regulate corneal progenitor cells and the transition to differentiation. Consistent with this notion, the K14-DN-Clim corneal epithelium first exhibits increased proliferation followed by fewer progenitor cells with decreased proliferative potential. In vivo ChIP-sequencing experiments with corneal epithelium show that CLIM binds to and regulates numerous genes involved in cell adhesion and proliferation, including limbally enriched genes. Intriguingly, CLIM associates primarily with non-LIM homeodomain motifs in corneal epithelial cells, including that of estrogen receptor α. Among CLIM targets is the noncoding RNA H19 whose deregulation is associated with Silver-Russell and Beckwith-Wiedemann syndromes. We demonstrate here that H19 negatively regulates corneal epithelial proliferation. In addition to cell cycle regulators, H19 affects the expression of multiple cell adhesion genes. CLIM interacts with estrogen receptor α at the H19 locus, potentially explaining the higher expression of H19 in female than male corneas. Together, our results demonstrate an important role for CLIM in regulating the proliferative potential of corneal epithelial progenitors and identify CLIM downstream target H19 as a regulator of corneal epithelial proliferation and adhesion.

HBV Outreach Programs Significantly Increase Knowledge and Vaccination Rates Among Asian Pacific Islanders.

Hepatitis B virus (HBV) testing and vaccination rates remain low among Asian-American/Pacific Islanders (APIs) despite high rates of HBV infection. The aim of our study was to assess the effectiveness of an outreach campaign to increase HBV knowledge, testing, and vaccination among a cohort of APIs. Vietnamese Americans were invited to participate in a free HBV screening and vaccination outreach program though pubic service announcements. Attendees completed a survey to assess barriers to vaccination and HBV-related knowledge before and after a 30-min education session by a bilingual board-certified gastroenterologist. Among 98 participants, 100% (22/22) of HBV naïve patients were provided a HBV vaccination series at no cost and over 75% (14/18) of HBV-infected patients were connected to further medical care. Notable reported barriers to prior testing and/or vaccination were cost of the vaccine, concern about missing work for evaluation, and lack of provider recommendation. Knowledge levels about HBV risk factors, potential consequences, and treatment options were poor at baseline but significantly increased after the education session (49 vs. 64%, p < 0.001). Outreach campaigns linked with education can successfully address several barriers to HBV testing and offer an approach to improve HBV awareness and prevention among difficult-to-reach populations.

Economic correlates of violent death rates in forty countries, 1962-2008: A cross-typological analysis.

OBJECTIVES: Our goal was to identify if there might be advantages to combining two major public health concerns, i.e., homicides and suicides, in an analysis with well-established macro-level economic determinants, i.e., unemployment and inequality. METHODS: Mortality data, unemployment statistics, and inequality measures were obtained for 40 countries for the years 1962-2008. Rates of combined homicide and suicide, ratio of suicide to combined violent death, and ratio between homicide and suicide were graphed and analyzed. A fixed effects regression model was then performed for unemployment rates and Gini coefficients on homicide, suicide, and combined death rates. RESULTS: For a majority of nation states, suicide comprised a substantial proportion (mean 75.51%; range 0-99%) of the combined rate of homicide and suicide. When combined, a small but significant relationship emerged between logged Gini coefficient and combined death rates (0.0066, p < 0.05), suggesting that the combined rate improves the ability to detect a significant relationship when compared to either rate measurement alone. Results were duplicated by age group, whereby combining death rates into a single measure improved statistical power, provided that the association was strong. CONCLUSIONS: Violent deaths, when combined, were associated with an increase in unemployment and an increase in Gini coefficient, creating a more robust variable. As the effects of macro-level factors (e.g., social and economic policies) on violent death rates in a population are shown to be more significant than those of micro-level influences (e.g., individual characteristics), these associations may be useful to discover. An expansion of socioeconomic variables and the inclusion of other forms of violence in future research could help elucidate long-term trends.
