RESUMO

BACKGROUND: Large-scale prostate cancer (PCa) database reviews have found a consistent discrepancy in the mortality rate in Black patients compared to their White counterparts. Furthermore, differences in PCa treatment and outcomes among Black men of different ethnic origins have also been identified. Due to the heterogeneity of PCa-impacted communities and the unclear impact of patient immigration status on treatment outcomes, we sought to determine the demographic factors associated with treatment choice for definitive treatment of PCa in our single institution's patient population of Black immigrants. METHODS: We distributed surveys to all patients in the Kings County Hospital Center urologic oncology clinic from February 2019 to February 2020 and collected relevant health information via EMR. The survey collected demographic information regarding age, education, health insurance, employment status, socioeconomic status, country of birth, and years living in the United States (US). RESULTS: Out of the 253 patients surveyed, the majority of patients surveyed were Black and foreign born. There were no significant differences in demographic data between US-born and foreign-born patients except number of years living in the United States. In the intermediate risk group, patients living in the United States for <10 years chose surgery significantly more often than US-born patients (90.9% vs. 50.0%, p = 0.036). On multivariate analysis, patients that chose surgery were more likely to be older when diagnosed (odds ratio [OR] = 1.21) and less likely to be born in the United States than in African or Caribbean countries (OR = 0.054). CONCLUSIONS: In our study of a majority-Black population, we found that patients born in the United States were less likely than their foreign counterparts to opt for surgery, as previous studies have shown. The choice of definitive treatment modality for Black men with intermediate risk PCa was found to be influenced by age at diagnosis and immigration status.

RESUMO

OBJECTIVE: Comprehensive Geriatric Assessment (CGA) has been proven to assist development of tailored treatment plans for older patients with cancer by identifying health issues affecting their ability to complete systemic therapy or cope with and recover from cancer treatment. MATERIALS AND METHODS: Metro North Hospital and Health Service (MNHHS) has significant older population with cancer. Geriatric Oncology services were commenced in February 2018 at two facilities of MNHHS [North Lakes Cancer Care Services/Caboolture Hospital (NLCCS/CBH) Cancer services and Redcliffe Hospital (RH) Cancer services]. The Geriatric 8 (G8) screening tool was administered to predict patient vulnerability and need for CGA. A bespoke CGA suite comprising of 16 assessments was used. A clinical nurse or Allied Health (AH) practitioner conducted screening, followed by CGA. Proposed care was discussed at multidisciplinary case conference and AH interventions were provided. RESULTS: From February'2018 to July'2019, the G8 was administered to 1380 patients between the two facilities (918 patients at NLCCS/CBH and 462 patients at RH), comprising oncology and haematology patients. 825 patients (59%) showed impairment on G8 and were recommended for CGA. Another 50 patients were referred for CGA as per clinical assessment despite normal G8. 65% (572) of recommended CGAs were conducted. The most common impairments identified on CGA leading to AH referrals were timed up & go >13 s, malnutrition, polypharmacy and low mood & depression. CONCLUSION: The nursing/AH practitioner led Geriatric Oncology service is feasible, applicable and beneficial to patients. Further study is planned to assess the impact of the service on patients' health related quality of life and chemotherapy completion rates.

RESUMO

Tumor heterogeneity is common in cancer, however recent studies have applied single gene expression signatures to classify bladder cancers into distinct subtypes. Such stratification assumes that a predominant transcriptomic signature is sufficient to predict progression kinetics, patient survival and treatment response. We hypothesize that such static classification ignores intra-tumoral heterogeneity and the potential for cellular plasticity occurring during disease development. We have conducted single cell transcriptome analyses of mouse and human model systems of bladder cancer and show that tumor cells with multiple lineage subtypes not only cluster closely together at the transcriptional level but can maintain concomitant gene expression of at least one mRNA subtype. Functional studies reveal that tumor initiation and cellular plasticity can initiate from multiple lineage subtypes. Collectively, these data suggest that lineage plasticity may contribute to innate tumor heterogeneity, which in turn carry clinical implications regarding the classification and treatment of bladder cancer.

RESUMO

Introduction According to the World Health Organization (WHO), foodborne diseases (FBD's) have become a global health issue. In Qatar, foodborne diseases are among the top ten events reported to the Ministry of Public Health. Efforts to enhance FBD surveillance cannot succeed without involving the emergency department (ED), which is typically the first point of contact for the FBD victims with the healthcare system. Therefore, we aimed to explore the knowledge and practices of emergency physicians regarding stool sample collection as part of FBD surveillance efforts in Qatar. Methods A cross-sectional study was conducted at the ED of Hamad General Hospital (HGH) between July 22 and September 12 of 2018. The enrolled participants were invited to participate in an online survey at the "QSurvey" platform. The data was analyzed using Microsoft Excel (Version 2016). Descriptive statistics such as frequency tables, proportions, and percentages were applied as appropriate. Results A total of 65 responses (response rate: 29.27%) were received within the duration of the study. Most participants were specialists (45%), graduated between 2000 and 2013 (64%), and worked for one year or more at HGH-Hamad Medical Corporation (95%). Regarding their knowledge of FBD surveillance, most participants (80%) reported that a stool culture is a necessary laboratory investigation for patients with acute bloody diarrhea and fever. Also, a large percentage of physicians identified salmonella (75%), Clostridium difficile (70%), and E.coli O157:H7 (70%) as pathogens of nationally notifiable diseases. Regarding the respondents' practice towards FBD surveillance, almost three-quarters of the physicians (72%) who encountered a patient with acute diarrhea did not order a stool culture. Subsequently, about two-thirds (62%) of the participants who requested a stool culture reported not following up on the results of such request. Regarding the history taken from patients with acute diarrhea, a large percentage of respondents reported asking about the patient's travel history (100%), presence of any sick contacts (93.6%), and presence of any associated symptoms (abdominal pain, fever, bloody stool) as well as other details. Conclusion The current research identified several gaps regarding the knowledge and practice of emergency physicians towards the surveillance of foodborne disease. Such results serve as a basis for future research and intervention strategies to augment surveillance activities related to food-borne diseases in the State of Qatar.

RESUMO

INTRODUCTION: Health administration is complex and serves many masters. Value, quality, infrastructure and reimbursement are just a sample of the competing interests influencing executive decision-making. This creates a need for decision processes that are rational and holistic. METHODS: We created a multicriteria decision analysis tool to evaluate six fields of healthcare provision: return on investment, capacity, outcomes, safety, training and risk. The tool was designed for prospective use, at the beginning of each funding round for competing projects. Administrators were asked to rank their criteria in order of preference. Each field was assigned a representative weight determined from the rankings. Project data were then entered into the tool for each of the six fields. The score for each field was scaled as a proportion of the highest scoring project, then weighted by preference. We then plotted findings on a cost-effectiveness plane. The project was piloted and developed over successive uses by the hospital's executive board. RESULTS: Twelve projects competing for funding at the Royal Brisbane and Women's Hospital were scored by the tool. It created a priority ranking for each initiative based on the weights assigned to each field by the executive board. Projects were plotted on a cost-effectiveness plane with score as the x-axis and cost of implementation as the y-axis. Projects to the bottom right were considered dominant over projects above and to the left, indicating that they provided greater benefit at a lower cost. Projects below the x-axis were cost-saving and recommended provided they did not harm patients. All remaining projects above the x-axis were then recommended in order of lowest to highest cost-per-point scored. CONCLUSION: This tool provides a transparent, objective method of decision analysis using accessible software. It would serve health services delivery organisations that seek to achieve value in healthcare.

RESUMO

Immunotherapy is being tested intensively in clinical trials for prostate cancer; it includes immune checkpoint inhibition, prostate specific antigen (PSA) vaccines and dendritic cell-based strategies. Despite increasing evidence for clinical responses, the consensus of multiple trials is that prostate cancers are poorly responsive to immunotherapy. Prostate cancer has a high degree of pathological and genetic heterogeneity compared to other cancer types, which may account for immunotherapeutic resistance. This hypothesis also implies that select types of prostate tumors may be differentially responsive to immune-based strategies and that the clinical stage, pathological grade and underlying genetic landscape may be important criteria in identifying tumors that respond to immune therapies. One strategy is to target oncogenic driver pathways in combination with immunotherapies with the goal of overcoming tumor immunity and broadening the number of patients achieving a clinical response. In this analysis, we address the hypothesis that driver oncogenic signaling pathways regulate cancer progression, tumor immunity and resistance to current immune therapeutics in prostate cancer. We propose that increased responsiveness may be achieved through the combined use of immunotherapies and inhibitors targeting tumor cell autonomous pathways that contribute towards anti-tumor immunity in patients with prostate cancer.

RESUMO

INTRODUCTION: International guidelines for basic life support and defibrillation are identical for lay people and healthcare professionals. In 2002, a small meeting hosted by the Resuscitation Council (UK) debated recent advances in resuscitation science, along with the possibility of more demanding procedures for treating out of hospital cardiac arrest (OHCA) that could take advantage of the expertise available with professional use. The resulting algorithm known as Protocol C could not be tested in a randomized trial for reasons relating to consent, but was introduced by one ambulance service as an observational study. Results from a 2-year period from one city within the service area are presented, using the Utstein style of reporting to show the recommended 'comparator' group whilst also providing epidemiological data on the frequency of cardiac arrest within the community and the outcome of all resuscitation attempts. METHODS: Manual methods were used to collect data from 2009 and 2010 for cases of cardiac arrest treated by crews from the two ambulance stations within the city of Brighton and Hove. All transported patients were tracked individually through the hospital because no official method of data linkage is available. Outcome data were obtained for survival to hospital discharge, or to 30 days for the few who remained in hospital care for that duration. RESULTS: In the epidemiological analysis, 454 patients with OHCA were treated over 2 years, of whom 151 (33%) had sustained return of spontaneous circulation (ROSC) at hospital handover and 59 (13%) survived to discharge or for 30 days. Within the 'comparator' group of 79 patients, 47 (59%) achieved sustained ROSC to hospital handover and 24 (30%) survived. CONCLUSION: The use of Protocol C has been associated with rates of sustained ROSC to hospital and of survival to discharge that have reached the range of international best practice. The improvement noted in this observational study cannot be ascribed to the new protocol alone; any wider use should await randomized trials to test the impact of this single variable. Meanwhile, wider adoption of the Utstein system to compare results for treatment of OHCA will provide a potent stimulus for emergency services to seek ways of improving outcome.

RESUMO

An intention in 2003 to undertake a multicentre trial in the United Kingdom of compressions before and after defibrillation could not be realized because of concerns at the time in relation to informed consent. Instead, the new protocol was introduced in one ambulance service, ahead of the 2005 Guidelines, with greater emphasis on compressions. The results were monitored by analysis of electronic ECG downloads. Deficiencies in the standard of basic life support were identified but were not unique to our service. The introduction of metronomes and the provision of feedback to crews led to major improvements in performance. Our experience has implications for the emergency pre-hospital care of cardiac arrest.
