Internal medicine residents' perceptions and experiences in palliative care: a qualitative study in the United Arab Emirates

Background

Palliative medicine is a newly developing field in the United Arab Emirates (UAE). The purpose of this study was to gain a deeper understanding of the experiences of internal medicine residents providing end-of-life care to patients and their families, and how those experiences shape their learning needs.

Method

Nine focus groups were conducted with internal medicine residents and recent graduates from two large academic health centers in the UAE between 2019 and 2020. Through an iterative process, data were collected and examined using constant comparison to identify themes and explore their relationships.

Results

Fifty-two residents and graduates participated. Residents frequently care for terminally ill patients and their families, but lack confidence in their skills and request more structured education and training. Cultural and system related factors also impact palliative care education and patient care. Five main themes and associated subthemes were identified: (1) clinical management of palliative patients, (2) patient and family communication skills, (3) religion, (4) barriers to end-of-life education, and (5) emotional impact of managing dying patients.

Conclusion

Our findings can help guide program development and curricular changes for internal medicine residents in the region. Structured education in end-of-life care, with a focus on fostering culturally sensitive communication skills and spirituality, can improve resident education and patient care. Clear and transparent policies at the institution level are necessary. Programs are also needed to assist residents in developing effective coping strategies and emotionally navigating experiences with patient death.

Identification of the functional alteration signatures across different cancer types with support vector machine and feature analysis

Cancers are regarded as malignant proliferations of tumor cells present in many tissues and organs, which can severely curtail the quality of human life. The potential of using plasma DNA for cancer detection has been widely recognized, leading to the need of mapping the tissue-of-origin through the identification of somatic mutations. With cutting-edge technologies, such as next-generation sequencing, numerous somatic mutations have been identified, and the mutation signatures have been uncovered across different cancer types. However, somatic mutations are not independent events in carcinogenesis but exert functional effects. In this study, we applied a pan-cancer analysis to five types of cancers: (I) breast cancer (BRCA), (II) colorectal adenocarcinoma (COADREAD), (III) head and neck squamous cell carcinoma (HNSC), (IV) kidney renal clear cell carcinoma (KIRC), and (V) ovarian cancer (OV). Based on the mutated genes of patients suffering from one of the aforementioned cancer types, patients they were encoded into a large number of numerical values based upon the enrichment theory of gene ontology (GO) terms and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. We analyzed these features with the Monte-Carlo Feature Selection (MCFS) method, followed by the incremental feature selection (IFS) method to identify functional alteration features that could be used to build the support vector machine (SVM)-based classifier for distinguishing the five types of cancers. Our results showed that the optimal classifier with the selected 344 features had the highest Matthews correlation coefficient value of 0.523. Sixteen decision rules produced by the MCFS method can yield an overall accuracy of 0.498 for the classification of the five cancer types. Further analysis indicated that some of these features and rules were supported by previous experiments. This study not only presents a new approach to mapping the tissue-of-origin for cancer detection but also unveils the specific functional alterations of each cancer type, providing insight into cancer-specific functional aberrations as potential therapeutic targets.

Pattern of gynaecological malignancies in south western region of Pakistan: An overview of 12 years

Gynaecological malignancies contribute significantly to cancer burden and have a higher rate of mortality and morbidity. The aim of this retrospective study was to determine the pattern of gynaecological malignancies identified between January, 2000 and December, 2011, at the Centre for Nuclear Medicine and Radiotherapy (CENAR). At CENAR 5,072 female patients were registered with different malignancies, of which 632 cases were gynaecological malignancies. Ovarian cancer (47%) was the most common gynaecological malignancy, followed by cervical cancer (29%), uterine cancer (14%), vulvar and vaginal cancer (6%), and gestational trophoblastic neoplasm (4%). Of the ovarian cancer cases, 72.5% had epithelial while 26.5% had non-epithelial cancer. Squamous cell carcinoma was 75.9% in cervix and 87.8% in vulva and vagina while endometrial carcinoma (75.9%) was more frequent in uterus. For gestational trophoblastic neoplasm, 69.2% of patients had choriocarcinoma. Ovarian cancer was the most common type for the age range of 50-59 years. In the case of cervical and gestational trophoblastic neoplasm the majority of patients presented at the ages of 40-49 and 30-39 years while uterus, vulvar and vaginal tumor presented in the elderly (>60 years). Thus, ovarian cancer is the leading gynecological malignancy in Pakistan.

Reported availability and gaps of pediatric palliative care in low- and middle-income countries: a systematic review of published data

BACKGROUND

The majority of young people in need of palliative care live in low- and middle-income countries, where curative treatment is less available.

OBJECTIVE

We systematically reviewed published data describing palliative care services available to young people with life-limiting conditions in low- and middle-income countries and assessed core elements with respect to availability, gaps, and under-reported aspects.

METHODS

PubMed, CINAHL, EMBASE (1980-2013), and secondary bibliographies were searched for publications that included patients younger than 25 years with life-limiting conditions and described palliative care programs in low- and middle-income countries. A data extraction checklist considered 15 items across seven domains: access, education/capacity building, health system support, pain management, symptom management, end-of-life care, and bereavement. Data were aggregated by program and country.

RESULTS

Of 1572 records, 238 met criteria for full-text review; 34 qualified for inclusion, representing 30 programs in 21 countries. The median checklist score was 7 (range, 1-14) of 10 reported (range, 3-14). The most pervasive gaps were in national health system support (unavailable in 7 of 17 countries with programs reporting), specialized education (unavailable in 7 of 19 countries with programs reporting), and comprehensive opioid access (unavailable in 14 of 21 countries with programs reporting). Underreported elements included specified practices for pain management and end-of-life support.

CONCLUSION

Comprehensive pediatric palliative care provision is possible even in markedly impoverished settings. Improved national health system support, specialized training and opioid access are key targets for research and advocacy. Application of a checklist methodology can promote awareness of gaps to guide program evaluation, reporting, and strengthening.

Ethical, Socioeconomic, and Cultural Considerations in Gynecologic Cancer Care in Developing Countries

Gynaecologic cancers contribute significantly to the cancer burden in developing countries, resulting in higher mortality and morbidity rates among women in these nations. This situation is further compounded by the occurrence of wars, famine, poverty and natural disasters, and infectious diseases like hepatitis B and HIV/AIDS. In addition, merge resources and manpower lack in these countries further compound this very delicate situation. Often times, socioeconomic, cultural, and ethical factors such as truth-telling, choice of place of care, place of death, treatment choices, medication use, and terminal sedation can interfere in patient management. Availability and use of oral morphine for pain relief, spiritual care and availability of palliative care services, the individuals’ autonomy, and family and community participation in care, end of life issues, and preservation of fertility are also big issues that determine the course of care. This review discusses these pertinent factors, discusses how they affect cancer care in women, and proffers ideas for healthcare workers and policy makers on implementation of sustainable models for cancer care in developing countries. Addressing socioeconomic, cultural, and ethical issues affecting gynaecologic cancer care will aid in ensuring development of viable models of cancer care in resource-limited countries.

Global inequalities in the care of women with cancer

Cancer is a leading cause of global mortality, and women in low- and middle- income countries are disproportionately affected due to vulnerabilities related to gender inequality, poverty and environmental factors. Cancers affecting women are given low priority in the developing world and resources for screening, diagnosing and treating cancer are limited. The Millennium Development Goals may serve as a guide to design programs that address the allocation of cancer services, equipment, medications and trained health care providers. This article aims to provide readers with strategies to advocate for gender parity in worldwide cancer control policies.
