Tafenoquine for Relapsing Babesiosis: A Case Series.

Background: Relapsing babesiosis often occurs in highly immunocompromised patients and has been attributed to the acquisition of resistance against drugs commonly used for treatment such as atovaquone, azithromycin, and clindamycin. Tafenoquine, which is approved for malaria prophylaxis and presumptive antirelapse treatment of Plasmodium vivax malaria, has shown activity against Babesia microti in several animal models of acute infection and in a single human case of relapsing babesiosis. Here, we report 5 cases of relapsing babesiosis treated with tafenoquine, including the previous case, and begin to define the conditions for optimal use of tafenoquine in relapsing babesiosis.

Radiation Oncology AcaDemic Mentorship Program (ROADMAP) for Junior Faculty: One-Year Results of a Prospective Single Institution Initiative.

Purpose: Although mentorship has been associated with promotion, job satisfaction, and retention, data are limited on the mentorship experience of clinical- versus research-track physicians as well as feasibility and relative priority of formal program components.

Methods And Materials: Within a single-institution, multi-site, academic network, we implemented a Radiation Oncology AcaDemic Mentorship Program (ROADMAP) for junior faculty. Validated surveys assessing mentee satisfaction were distributed at baseline and 1 year.

Prolonged SARS-CoV-2 Infection in Patients with Lymphoid Malignancies.

Coronavirus disease 2019 (COVID-19) infection results in both acute mortality and persistent and/or recurrent disease in patients with hematologic malignancies, but the drivers of persistent infection in this population are unknown. We found that B-cell lymphomas were at particularly high risk for persistent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positivity. Further analysis of these patients identified discrete risk factors for initial disease severity compared with disease chronicity.

Variable duration of viral shedding in cancer patients with coronavirus disease 2019 (COVID-19).

In this retrospective study of 105 severe acute respiratory coronavirus virus 2 (SARS-CoV-2)-infected cancer patients with longitudinal nasopharyngeal sampling, the duration of viral shedding and time to attain cycle threshold >30 was longer in patients with hematologic malignancy than in those with solid tumors. These findings have important public health implications.

Severe Acute Respiratory Syndrome Coronavirus 2 Surveillance and Exposure in the Perioperative Setting With Universal Testing and Personal Protective Equipment Policies.

Background: New York City (NYC) experienced a surge of coronavirus disease 2019 (COVID-19) cases in March and April 2020. Since then, universal polymerase chain reaction (PCR)-based surveillance testing and personal protective equipment (PPE) measures are in wide use in procedural settings. There is limited published experience on the utility and sustainability of PCR-based surveillance testing in areas with receding and consistently low community COVID-19 rates.

Vaccination of the Stem Cell Transplant Recipient and the Hematologic Malignancy Patient.

Patients with hematologic malignancy or those who undergo hematopoietic stem cell transplantation experience variable degrees of immunosuppression, dependent on underlying disease, therapy received, time since transplant, and complications, such as graft-versus-host disease. Vaccination is an important strategy to mitigate onset and severity of certain vaccine-preventable illnesses, such as influenza, pneumococcal disease, or varicella zoster infection, among others. This article highlights vaccines that should and should not be used in this patient population and includes general guidelines for timing of vaccination administration and special considerations in the context of newer therapies, recent vaccine developments, travel, and considerations for household contacts.

Immunizing Cancer Patients: Which Patients? Which Vaccines? When to Give?

Patients receiving treatment for cancer should be considered for age- and indication-appropriate vaccinations, and the responsibility for administration of these vaccines is shared between the oncologist and the primary care provider. Certain vaccine-preventable diseases have higher incidence rates among cancer patients and are associated with worse clinical outcomes. The Centers for Disease Control and Prevention and the Advisory Committee on Immunization Practices recommend certain vaccines for routine use in adults, including those with cancer.

Patient Death Debriefing Sessions to Support Residents' Emotional Reactions to Patient Deaths.

Background: There is no standard way to help residents deal with the emotional impact of patient deaths. Most available curricula are time and resource intensive.

Objective: We introduced "Patient Death Debriefing Sessions" into an inpatient medical oncology rotation at Memorial Sloan Kettering Cancer Center to provide a structured yet practical way to address residents' emotional reactions following the death of a patient.

International travel patterns and travel risks for stem cell transplant recipients.

Background: Stem cell transplantation (SCT) is being increasingly utilized for multiple medical illnesses. However, there is limited knowledge about international travel patterns and travel-related illnesses of stem cell transplant recipients (SCTRs).

Methods: An observational cross-sectional study was conducted among 979 SCTRs at Memorial Sloan Kettering Cancer Center using a previously standardized and validated questionnaire.

Tolerability of chemotherapy in HIV-infected women with breast cancer: are there prognostic implications?

Breast cancer is the most commonly diagnosed malignancy in women, but little is known about therapeutic outcomes in patients with both breast cancer and HIV. We performed a retrospective cohort study of women with or without HIV undergoing treatment for breast cancer from 1996 to 2011. Cases with HIV were 1:2 matched to non-HIV controls based on age, sex, race, and date of cancer diagnosis.

International travel patterns and travel risks of patients diagnosed with cancer.

Background: Immunocompromised travelers living with cancer can be at increased risk of travel-related illnesses. Their international travel patterns and associated risks remain largely unknown.

Methods: This was a retrospective cohort study of all patients diagnosed with cancer who presented for pre-travel health advice between January 1, 2003 and June 30, 2011.

The Neurological Outcome Scale for Traumatic Brain Injury (NOS-TBI): I. Construct validity.

The Neurological Outcome Scale for Traumatic Brain Injury (NOS-TBI) is a measure adapted from the National Institutes of Health Stroke Scale (NIHSS), and is intended to capture essential neurological deficits impacting individuals with traumatic brain injury (TBI) (see Wilde et al., 2010 ). In the present study we evaluate the measure's construct validity via comparison with a quantified neurological examination performed by a neurologist.

Determination of organophosphorus fire retardants and plasticizers in wastewater samples using MAE-SPME with GC-ICPMS and GC-TOFMS detection.

Determination of organophosphorus fire retardants and plasticizers at trace levels in wastewater is described. In this work, microwave assisted extraction (MAE) and solid-phase microextraction (SPME) are used for sample preparation to extract and preconcentrate the analytes, followed by analysis by gas chromatography coupled to inductively coupled plasma mass spectrometry (GC-ICP-MS) for phosphorus-specific detection. Gas chromatography coupled to time of flight mass spectrometry (GC-TOF-MS) was used to confirm the organphosphorus fire retardants in wastewater.

Relative mass defect filtering of high-resolution mass spectra for exploring minor selenium volatiles in selenium-enriched green onions.

In this study, the presence of minor Se-containing volatiles in Se-enriched green onions (Allium fistulosum) was investigated using the combination of high-resolution mass spectrometry, inductively coupled plasma mass spectrometry, and a simple relative mass defect-based algorithm to aid trace level analysis of unknown components. This confirmed the structures of volatiles reported previously, along with several unreported small molecular weight Se-containing volatiles from plants, such as MeSeSeSMe. This data analysis technique was also useful to link the results obtained from molecular and elemental mass spectrometry thus aiding in the search for new trace level Se-containing volatiles.

Rehabilitation of the older adult with stroke.

Stroke is an increasing public health concern throughout the world as the leading cause of long-term disability. It is well known that there exist differences related to epidemiology, pathophysiology, comorbidity, and functional outcome of stroke patients with advanced age compared with the young. Factors that have been suggested to influence this disparity include age-related complications, availability of resources, lack of aggressive management, and possible diminished capacity for neuroplasticity.

Determination of phosphoric acid triesters in human plasma using solid-phase microextraction and gas chromatography coupled to inductively coupled plasma mass spectrometry.

A simple and sensitive method for determination of phosphoric acid triesters at trace levels in human plasma sample is described. In this work, solid-phase microextraction (SPME) is employed as a sample preparation procedure for extraction and pre-concentration of alkyl and aryl phosphates followed by gas chromatography coupled to inductively coupled plasma mass spectrometry (GC-ICP-MS) for phosphorus-specific and very sensitive determination of these compounds in human plasma. The detection limits from blood plasma were 50 ngL(-1) (tripropyl phosphate), 17 ngL(-1) (tributyl phosphate), 240 ngL(-1) (tris(2-chloroethyl) phosphate) and 24 ngL(-1) (triphenyl phosphate).
