Hemichorea-hemiballismus associated with a case of cerebral toxoplasmosis in a hematopoietic stem cell transplant recipient.

Due to their immunocompromised state, recipients of hematopoietic stem cell transplants (HSCTs) are at a higher risk of opportunistic infections, such as that of toxoplasmosis. Toxoplasmosis is a rare but mortal infection that can cause severe neurological symptoms, including confusion. In immunosuppressed individuals, such as those with acquired immunodeficiency syndrome (AIDS), toxoplasmosis can cause movement disorders, including hemichorea-hemiballismus. We present the case of a 54-year-old Caucasian male with a history of hypertension and JAK-2-negative primary myelofibrosis who underwent an allogeneic peripheral blood stem cell transplant from a related donor. After the development of acute changes in mental status, left-sided weakness, and left-sided hemichorea-hemiballismus post-transplant, the patient was readmitted to the hospital. Subsequent testing included an magnetic resonance imaging (MRI) of the brain, which revealed multiple ring-enhancing lesions around the thalami and basal ganglia, as well as a cerebrospinal fluid tap that tested positive for toxoplasmosis. The patient was initially treated with intravenous clindamycin and oral pyrimethamine with leucovorin. The completion of treatment improved the patient's mental status but did not improve his hemichorea-hemiballismus. This case illustrates an uncommon complication associated with central nervous system (CNS) toxoplasmosis in stem cell transplant recipients. Due to its rarity, cerebral toxoplasmosis in immunocompromised patients often remains undetected, particularly in HSCT patients who are immunosuppressed to improve engraftment. Neurological and neuropsychiatric symptoms due to toxoplasmosis may be misidentified as psychiatric morbidities, delaying appropriate treatment. Polymerase chain reaction (PCR) assays offer methods that are sensitive and specific to detecting toxoplasmosis and provide opportunities for early intervention.

Cultural adaptation process of cancer-related interventions: A step-by-step guide.

INTRODUCTION: To contribute to the reduction and elimination of cancer-related local and global health disparities, interventions must be culturally adapted to reach diverse cultural groups and demonstrate success in improving clinical and psychosocial outcomes. We provide step-by-step information on the conceptual and methodological challenges involved in culturally adapting interventions and provide guidelines, suggestions, tools, and concrete steps for implementing the process. METHODS: This article provides information, guidelines, suggestions, tools, and concrete steps, based on three rigorous models of cultural adaptations, for implementing this process, followed with examples from the field, to illustrate the conceptual and methodological challenges involved in culturally adapting interventions. CONCLUSION: Our systematic step-by-step approach recommends (1) the guidance of well-established research models; (2) use of multiple data sources and input from various stakeholders (i.e., from patients and providers); (3) qualitative and quantitative data usage and integration; (4) a steering committee with multiple perspectives, stakeholders assessments, and qualitative analyses; (5) consensus meetings; and (6) diverse representation on the steering committee and/or research team.

Pretransplantation Cognitive Dysfunction in Advanced-Age Hematologic Cancers: Predictors and Associated Outcomes.

Patients presenting for treatment of hematologic cancers may be at increased risk for cognitive dysfunction before allogeneic hematopoietic stem cell transplantation (HSCT) due to advanced age, previous chemotherapy treatment, deconditioning, and fatigue. Cognitive dysfunction may affect treatment decision making, ability to recall or follow post-HSCT treatment recommendations and overall survival (OS). A total of 448 patients admitted for HSCT between 2011 and 2014 were administered the Montreal Cognitive Assessment (MoCA) by occupational therapists during admission before transplantation, and 260 were reassessed following transplantation and before discharge. We examined select predictor variables, including age, Karnofsky Performance Status, sex, disease type, psychotropic medications, and select outcome variables, including OS, and nonrelapse mortality (NRM). Before transplantation, 36.4% of patients met criteria for cognitive dysfunction. Age was found to be a significant predictor, along with disease type (myelodysplastic syndrome [MDS], myeloproliferative disorder [MPD]). No significant association was found between cognitive dysfunction and OS or NRM. Longitudinal analysis from pretransplantation to post-transplantation indicated significant decline following HSCT. Notably, one-third of the study cohort showed cognitive dysfunction at hospital discharge. A significant proportion of HSCT candidates present with cognitive dysfunction, with older patients and those diagnosed with MDS and MPD at greatest risk in this cohort. Attention to cognitive dysfunction before transplantation may alert the treatment team to high-risk cases that require increased oversight, inclusion by caregivers, and referral to occupational therapy at discharge. Longitudinal follow-up studies are needed to clarify the specific effect of HSCT on cognitive dysfunction and the impact of cognitive dysfunction on transplantation outcomes.

Aromatase inhibitors and mood disturbances.

We describe the case of a 56-year old woman with no prior psychiatric history who was diagnosed with hormone receptor positive early-stage breast cancer and who developed severe mood changes after administration of anastrozole, which resolved after discontinuation of treatment. Aromatase inhibitors (AIs) are the preferred hormonal approach for postmenopausal women with estrogen hormone sensitive breast cancer. The third-generation agents (anastrozole, letrozole, and exemestane) have been shown to be more effective and safer than the selective estrogen receptor modulators tamoxifen and raloxifen. Treatment strategies with these agents include the use of an AI as an upfront strategy for 5 years, as a sequential approach after 2-3 years of tamoxifen, or as extended use after the classical 5 years of tamoxifen. The side effects of AIs, as compared with selective estrogen receptor modulators, are different, reflecting the specific mechanism of action of these drugs. AIs are well tolerated and cause a lower incidence of gynecological symptoms (vaginal bleeding, discharge, and endometrial neoplasia), venous thromboembolic events, and hot flashes compared with tamoxifen. However, the use of AIs have been associated with loss of bone density, arthralgia, myalgia, a negative effect on lipid metabolism, and cardiovascular risk (Tomao et al., 2011). Mood disturbances, somnolence, anxiety, fatigue, hot flashes, and memory impairment have been reported among patients receiving anastrozole as adjuvant therapy.
