A Case of Fulminant Cerebral Edema Leading to Death After Chimeric Antigen Receptor T-Cell Therapy.

Chimeric antigen receptor (CAR) T-cell therapy has transformed treatment of refractory B-cell malignancies; however, treatment puts patients at risk for side effects secondary to the amplified immune response it induces. Fulminant cerebral edema (FCE) is one of the rarest, yet most devastating side effects following CAR T-cell therapy. Due to this rarity, FCE has not been well characterized and the risk factors associated with its development are not fully understood.

Successful Treatment of Refractory Post-Transplant Lymphoproliferative Disorder With Chimeric Antigen Receptor T-Cell Therapy in a Heart Transplant Recipient.

Post-transplant lymphoproliferative disorders (PTLDs) are opportunistic malignancies that complicate the success of hematopoietic stem cell or solid organ transplantation. These disorders often arise post-transplant due to the immunosuppression required for minimizing the risk of rejection of donor tissue. First-line treatment of these disorders includes limiting immunosuppression when permissible.

Revisiting the Clinical Interpretation of CT-Measured Pulmonary Artery-to-Aorta Ratio-The Rotterdam Study.

Rationale: The pulmonary artery (PA) diameter-to-aorta ratio (PA:A) ratio is a novel marker in cardiovascular imaging for detecting pulmonary hypertension. However, we question the effect of the varying aorta diameter on the ratio, which complicates the interpretation of the PA:A ratio.

Objective: Investigate the variability of the PA:A ratio by examining the correlation between PA:A ratio and aorta diameter and by comparing the associations of the PA diameter, aorta diameters, and PA:A ratio.

Placebo Control and Blinding in Randomized Trials of Procedural Interventions: A Systematic Review and Meta-Regression.

Importance: Unlike medications, procedural interventions are rarely trialed against placebo prior to becoming accepted in clinical practice. When placebo-controlled trials are eventually conducted, procedural interventions may be less effective than previously believed.

Objective: To investigate the importance of including a placebo arm in trials of surgical and interventional procedures by comparing effect sizes from trials of the same procedure that do and do not include a placebo arm.

Considerations for the Future: Family Planning and Infertility During Psychiatry Training.

During medical school, residency, or fellowship, many trainees struggle to balance their careers with starting a family. Some may feel the optimal time for parenthood is after completion of training, but the effect of increasing age on fertility is a real consideration for female physicians. Several studies have explored the impact of pregnancy and parental leave during surgical residency, yet little has been published on these topics during psychiatry training.

Using Drosophila to uncover the role of organismal physiology and the tumor microenvironment in cancer.

Cancer metastasis causes over 90% of cancer patient fatalities. Poor prognosis is determined by tumor type, the tumor microenvironment (TME), organ-specific biology, and animal physiology. While model organisms do not fully mimic the complexity of humans, many processes can be studied efficiently owing to the ease of genetic, developmental, and cell biology studies.

Incidence of malignant pericardial effusion in pericardiocentesis patients and post-procedure care: an oncology center pilot study.

The etiology of pericardial effusion can affect many important factors during and after pericardiocentesis. The frequency of etiologies varies among different patient populations. Pericardiocentesis is an important diagnostic and therapeutic intervention; however, data on the characteristics of malignant pericardial effusion are lacking in the United Arab Emirates (UAE).

A Meningioma Mimic and Distinct Subtype of Primary Central Nervous System Lymphoma: Primary Dural Lymphoma.

Primary central nervous system lymphoma (PCNSL) is an aggressive form of extranodal non-Hodgkin lymphoma that arises in the brain parenchyma, eyes, meninges, or spinal cord in the absence of systemic disease. Primary dural lymphoma (PDL), in contrast, arises from the dura mater of the brain. PDL is usually a low-grade B-cell marginal zone lymphoma (MZL), whereas other types of PCNSL are usually high-grade large B-cell lymphoma.

Treatment Selection and Survival in Patients with Gray Zone Lymphoma: A Comprehensive Population-Based Analysis.

Background And Objectives: There are no treatment guidelines for gray-zone lymphoma (GZL), given the disease's rarity and being a relatively new entity. Our objective was to assess factors affecting treatment selection in GZL and its effect on survival, focusing on combined modality treatment (CMT) versus chemotherapy alone.

Patients And Methods: We identified 1047 patients with GZL treated with CMT or chemotherapy alone between 2004 and 2016 from the National Cancer Database (NCDB).

Pharmacodynamic Modeling Identifies Synergistic Interaction Between Chloroquine and Trastuzumab in Refractory HER2- positive Breast Cancer Cells.

Background/aim: Despite improvements in HER2-positive breast cancer (BC) patients' outcomes with trastuzumab, the occurrence of intrinsic or acquired resistance presents a clinical challenge. Here, we quantitatively assess the combinatorial effects of chloroquine, an autophagy inhibitor, with trastuzumab on JIMT-1 cells, a HER2-positive BC cell-line primarily resistant to trastuzumab.

Materials And Methods: The temporal changes in JIMT-1 cellular viability were assessed using the CCK-8 kit, where JIMT-1 cells were exposed for 72-h to trastuzumab (0.

Primary Testicular Lymphoma: Single Center Experience.

Background/aim: Primary testicular lymphoma (PTL) is an exceedingly rare and aggressive form of non-Hodgkin's lymphoma; the most common subtype is diffuse large B-cell (DLBCL). Standard treatment includes orchiectomy, chemotherapy, central nervous system (CNS) prophylaxis, and prophylactic radiation to the contralateral testis. PTL can reoccur years after complete remission.

A Global Survey of Hypervirulent Aeromonas hydrophila (vAh) Identified vAh Strains in the Lower Mekong River Basin and Diverse Opportunistic Pathogens from Farmed Fish and Other Environmental Sources.

Hypervirulent Aeromonas hydrophila (vAh) has emerged as the etiologic agent of epidemic outbreaks of motile septicemia (MAS) in high-density aquaculture of farmed carp in China and catfish in the United States, which has caused millions of tons of lost fish. We conducted a global survey to better understand the evolution, geographical distribution, and phylogeny of vAh. isolates were isolated from fish that showed clinical symptoms of MAS, and pure cultures were screened for the ability to utilize -inositol as the sole carbon source.

Annotating very high-resolution satellite imagery: A whale case study.

The use of very high-resolution (VHR) optical satellites is gaining momentum in the field of wildlife monitoring, particularly for whales, as this technology is showing potential for monitoring the less studied regions. However, surveying large areas using VHR optical satellite imagery requires the development of automated systems to detect targets. Machine learning approaches require large training datasets of annotated images.

Adipose derived stem cells for the peripheral nerve regeneration: review of techniques and clinical implications.

Adipose tissue is considered as a multipotent organ with multiple cellular varieties, like adipose derived stem cells with ability to differentiate into nerve cells. This review is an attempt to summarize the techniques of harvesting, isolating and delivery of adipose derived stem cells to injured nerve area and various interactions involved in the release of neurotrophic and angiogenic factors from stem cells. Neuro-regenerative potential of ADSCs is explained on the basis of "Paracrine hypothesis", according to which ADSCs secrete multiple neurotrophic factors and upregulates secretion of these neurotrophic factors by Schwann cells, leading to improved myelination, regeneration and decreases nerve fibrosis.

CD38-specific nanobodies allow imaging of multiple myeloma under daratumumab therapy.

Rationale: Recent studies have demonstrated the feasibility of CD38-specific antibody constructs for imaging of multiple myeloma. However, detecting multiple myeloma in daratumumab-pretreated patients remains difficult due to overlapping binding epitopes of the CD38-specific imaging antibody constructs and daratumumab. Therefore, the development of an alternative antibody construct targeting an epitope of CD38 distinct from that of daratumumab is needed.

Safety and efficacy of atezolizumab with rituximab and CHOP in previously untreated diffuse large B-cell lymphoma.

Rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the current standard therapy for patients with diffuse large B-cell lymphoma (DLBCL) and is curative in ∼60% of patients. Atezolizumab is a humanized immunoglobulin G1 monoclonal antibody that targets programmed death-ligand 1 and has previously shown antitumor activity in several tumor types. In a phase 1b/2 trial (NCT02596971), we evaluated the safety and efficacy of atezolizumab in combination with R-CHOP (atezo-R-CHOP; for 6-8 cycles) in patients with previously untreated DLBCL.

Breast cancer incidence among women with a family history of breast cancer by relative's age at diagnosis.

Background: Women with a first-degree family history of breast cancer are often advised to begin screening when they are 10 years younger than the age at which their relative was diagnosed. Evidence is lacking to determine how much earlier they should begin.

Methods: Using Breast Cancer Surveillance Consortium data on screening mammograms from 1996 to 2016, the authors constructed a cohort of 306,147 women 30-59 years of age with information on first-degree family history of breast cancer and relative's age at diagnosis.

Venetoclax-induced vitiligo in a patient with chronic lymphocytic leukemia.

Venetoclax, a highly selective Bcl-2 inhibitor, is an orally bioavailable drug that has been approved as first-line therapy for chronic lymphocytic leukemia (CLL) in combination with obinutuzumab, as well as monotherapy in the setting of relapsed CLL. Although some of its life-threatening side effects are well known, including tumor lysis syndrome and cytopenias, others less known side effects include skin reactions. Skin rash is commonly reported in literature, which is often mild and not life-threatening.

Reading the mind in the eyes in PTSD: Limited Moderation by the presence of a service dog.

Persons with posttraumatic stress disorder (PTSD) frequently experience relationship failures in family and occupational domains resulting in loss of social supports. Prior research has implicated impairments in social cognition. The Reading the Mind in the Eyes Test (RMET) measures a key component of social cognition, the ability to infer the internal states of other persons based on features of the eyes region of the face; however, studies administering this popular test to persons with PTSD have yielded mixed results.
