External Validation of the BACES Score in Canadian Patients With Nontuberculous Mycobacterial Pulmonary Disease.

BACKGROUND: The clinical course of nontuberculous mycobacterial pulmonary disease (NTM-PD) can be variable and difficult to predict. Recently, the BACES score was developed as a tool to predict all-cause mortality in patients with NTM-PD. This score is calculated based on five patient characteristics (BMI, age, cavity, erythrocyte sedimentation rate, and sex), and higher scores portend worse prognosis. Although the BACES score has been validated in a cohort of South Korean patients, it has not yet been validated in other settings or ethnic groups. RESEARCH QUESTION: How well does the BACES mortality score perform in a cohort of Canadian patients with NTM-PD? STUDY DESIGN AND METHODS: We performed a single-center retrospective chart review. Patients who were seen between July 2003 and June 2021 were eligible for inclusion if they met guideline-based diagnostic criteria for NTM-PD and were excluded if any component of the BACES score was missing. To assess the model's discriminatory performance, we compared Kaplan-Meier curves between risk groups and calculated Harrell's C index. To assess calibration, we used a graphical calibration curve. RESULTS: The cohort included 435 patients with a median follow-up of 5.8 years. The median age was 64 years and 74% were female. Based on the BACES scores, patients were classified into three risk groups: low, moderate, or high. Survival curves showed clear separation of the risk groups. Harrell's C index was 0.733 in the study cohort, indicating moderate to good discriminatory performance, although this was lower than the value reported in the derivation cohort (0.812). The graphical calibration curve showed a tendency of the BACES model to underpredict mortality. INTERPRETATION: The BACES model was evaluated in a multicultural cohort of Canadian patients and demonstrated good discriminatory performance but suboptimal calibration, which may be due to population differences, the use of dichotomized variables in model construction, or both.

Disseminated Cryptococcus neoformans presenting with an isolated pleural effusion in a patient receiving temozolomide and long-term steroids.

Cryptococcus neoformans is a ubiquitous environmental organism found worldwide. Infection with this organism occurs predominantly in immunocompromised hosts, including persons living with HIV or those with impaired cellular immunity. Cryptococcal pleural effusions have been described in cases with extensive pulmonary involvement. Here we present the case of a woman receiving temozolomide and steroids for glioblastoma multiforme, who developed cough and dyspnoea and was found to have an uncomplicated pleural effusion. Pleural fluid culture grew Cryptococcus neoformans with negative culture on bronchoalveolar lavage. High serum cryptococcal antigen titre of 1:64 prompted lumbar puncture which demonstrated positive cerebrospinal fluid for Cryptococcus neoformans She was treated with liposomal amphotericin B and flucytosine, followed by consolidation and maintenance therapy with fluconazole. Pleural involvement in the absence of pulmonary involvement has rarely been reported. We review pulmonary and radiographic manifestations of cryptococcal infection, when to assess for disseminated infection, and management principles.

The experience of medical communication in adults with acute leukemia: Impact of age and attachment security.

BACKGROUND: Health care providers' (HCPs) communication with cancer patients provides both information and support. Younger patient age and greater difficulty accepting support (attachment security) have been linked to poorer communication experiences with HCPs. The present secondary data analysis examined the impact of age group and attachment security on perceived communication problems with HCPs in adults with acute leukemia (AL). METHODS: The sample included 95 younger (age < 40 years) and 225 older (age ≥ 40 years) patients with newly diagnosed or recently relapsed AL. We assessed avoidant and anxious attachment security (reluctance to accept support and fear of its unavailability, respectively) with the modified 16-item Experiences in Close Relationships Scale. The impact of age group and attachment security on perceived communication problems, measured with the Cancer Rehabilitation Evaluation System-Medical Interaction Subscale, was assessed based on the presence and extent of communication problems. RESULTS: Younger patients (OR = 1.79-1.82, P = .030) and those with greater avoidant (OR = 1.44, P = .001) or anxious attachment (OR = 1.38, P = .009) were more likely to report communication problems. A similar relationship was found between age (ß's = -.17-.19, P = .015-.025), avoidant (ß = .29, P = .013), or anxious attachment (ß = .17, P = .031), and the extent of communication problems. A significant age-group × avoidant-attachment interaction (ß = -.31, P = .008) suggested that more avoidant attachment was associated with more perceived communication problems in the younger but not in the older group. CONCLUSIONS: Younger patients with AL, especially those more reluctant to seek or accept support, perceive more communication problems with their HCPs than older patients. Greater attention by HCPs to their communication with younger patients is needed.

Palliative Care Development in Africa: Lessons From Uganda and Kenya.

PURPOSE: Despite increased access to palliative care in Africa, there remains substantial unmet need. We examined the impact of approaches to promoting the development of palliative care in two African countries, Uganda and Kenya, and considered how these and other strategies could be applied more broadly. METHODS: This study reviews published data on development approaches to palliative care in Uganda and Kenya across five domains: education and training, access to opioids, public and professional attitudes, integration into national health systems, and research. These countries were chosen because they are African leaders in palliative care, in which successful approaches to palliative care development have been used. RESULTS: Both countries have implemented strategies across all five domains to develop palliative care. In both countries, successes in these endeavors seem to be related to efforts to integrate palliative care into the national health system and educational curricula, the training of health care providers in opioid treatment, and the inclusion of community providers in palliative care planning and implementation. Research in palliative care is the least well-developed domain in both countries. CONCLUSION: A multidimensional approach to development of palliative care across all domains, with concerted action at the policy, provider, and community level, can improve access to palliative care in African countries.
