RESUMO
Upfront autologous stem cell transplantation (auto-SCT) remains standard of care for eligible patients with newly diagnosed multiple myeloma (NDMM), although recently its role has been questioned. The aim of the study was to evaluate trends in patient characteristics, treatment, and outcomes of NDMM who underwent upfront auto-SCT over three decades. We conducted a single-center retrospective analysis of patients with NDMM who underwent upfront auto-SCT at MD Anderson Cancer Center between 1988 to 2021. Primary end points were progression-free survival (PFS) and overall survival (OS). Patients were grouped by the year of auto-SCT: 1988-2000 (n = 249), 2001-2005 (n = 373), 2006-2010 (n = 568), 2011-2015 (n = 815) and 2016-2021 (n = 1036). High-risk cytogenetic abnormalities were defined as del (17p), t (4;14), t (14;16), and 1q21 gain or amplification by fluorescence in situ hybridization. We included 3041 MM patients in the analysis. Median age at auto-SCT increased from 52 years (1988-2000) to 62 years (2016-2021), as did the incidence of high-risk cytogenetics from 15% to 40% (P < .001). Comorbidity burden, as measured by a Hematopoietic Cell Transplantation-Specific Comorbidity Index (HCT-CI) of >3, increased from 17% (1988-2000) to 28% (2016-2021) (P < .001). Induction regimens evolved from predominantly chemotherapy to immunomodulatory drug (IMiD) and proteasome inhibitor (PI) based regimens, with 74% of patients receiving IMiD-PI triplets in 2016-2021 (39% bortezomib, lenalidomide and dexamethasone (VRD) and 35% carfilzomib, lenalidomide and dexamethasone [KRD]). Response rates prior to auto-SCT steadily increased, with 4% and 10% achieving a ≥CR and ≥VGPR compared to 19% and 65% between 1988-2000 and 2016-2021, respectively. Day 100 response rates post auto-SCT improved from 24% and 49% achieving ≥CR and ≥VGPR between 1988-2000 to 41% and 81% between 2016-2021, respectively. Median PFS improved from 22.3 months between 1988-2000 to 58.6 months between 2016-2021 (HR 0.42, P < .001). Among patients with high-risk cytogenetics, median PFS increased from 13.7 months to 36.8 months (HR 0.32, P < .001). Patients aged ≥65 years also had an improvement in median PFS from 33.6 months between 2001 and 2005 to 52.8 months between 2016-2021 (HR 0.56, P = .001). Median OS improved from 55.1 months between 1988-2000 to not reached (HR 0.41, P < .001). Patients with high-risk cytogenetics had an improvement in median OS from 32.9 months to 66.5 months between 2016-2021 (HR 0.39, P < .001). Day 100 non-relapse mortality from 2001 onwards was ≤1%. Age-adjust rates of second primary malignancies were similar in patients transplanted in different time periods. Despite increasing patient age and comorbidity burden, this large real-world study demonstrated significant improvements in the depth of response and survival outcomes in patients with NDMM undergoing upfront auto-SCT over the past three decades, including those with high-risk disease.

PURPOSE: Vaccinations are essential in minimizing the effects of global health crises including COVID-19 pandemic. This study investigates the potential association between COVID-19 vaccination and the occurrence of medium vessel vasculitis. METHODS: Several databases were utilized to conduct a comprehensive literature review. The studies were carefully evaluated to ensure their quality and eliminate any potential bias. RESULTS: After reviewing 935 search results and removing duplicates, we selected 10 case reports. We discovered that medium vessel vasculitis may occur after COVID-19 vaccination, typically appearing around 16.2 days after vaccination. The patients in the study had a median age of 43.5 years and were predominantly males (80%). Additionally, half of the cases were reported after the second dose of vaccination. CONCLUSIONS: Vaccination-associated vasculitis is a rare yet possible complication of COVID-19 vaccination and lacks a clear treatment protocol.

Key Clinical Message: Tuberculosis (TB) of the odontoid process is a rare but potentially, a debilitating condition. Surgical intervention, in the form of stabilizing the spine and decompressing the spinal cord, offers a tailored approach to managing this condition effectively and improving prognosis. Abstract: Odontoid process tuberculosis (TB) is a rare condition that can cause spinal instability and neurological complications. Diagnosis of odontoid process TB is difficult and requires a combination of clinical, radiographic, and histopathological examinations. This report describes the treatment of a 46-year-old female with quadriparesis and intermittent fever. Radiological findings showed TB of the odontoid process with atlanto-axial dislocation causing compressive myelopathy. She underwent C1-C3 decompressive laminectomy and stabilization from C1 to C5. GeneXpert for TB was positive and she was started on anti-tuberculous medications. She regained power gradually and at 1 year follow-up she was ambulant without any support. The C1-C5 lateral mass screw and C1-C3 decompressive laminectomy approach, as highlighted in this case, offers an effective solution, enhancing patient quality of life, and preventing disease progression.
RESUMO
Atrial fibrillation (AF) is a prevalent cardiac dysrhythmia, particularly affecting older adults, with its prevalence rising due to the aging population. AF is linked to several adverse outcomes, including embolic stroke, heart failure, and cancer. The association between AF and cancer is intricate and not yet fully understood. Studies suggest that the rise in cancer survivorship, along with cancer treatments, may contribute to an increased incidence of AF among cancer patients. This literature review was conducted using various databases to explore the relationship between AF and cancer. Studies from 2002 to 2022 were included, focusing on the adult population. Independent authors evaluated and validated the studies, ensuring rigorous methodology. The connection between AF and cancer appears multifaceted. There is evidence of increased cancer incidence within the first few months following an AF diagnosis, with potential shared risk factors like age, obesity, and smoking. Medications used to treat AF, notably amiodarone, were associated with increased cancer risk. Colon cancer risk might be linked to anticoagulation-induced gastrointestinal bleeding. It remains uncertain whether AF diagnosis leads to early cancer detection or if cancer itself contributes to AF development. The complex interplay between AF and cancer involves shared risk factors, potential medication-related influences, and unclear causal directions. The intricacies of this relationship warrant further research to clarify the underlying mechanisms and potential interactions. A comprehensive meta-analysis could provide more insights into this intriguing association and guide future clinical interventions.
RESUMO
BACKGROUND: Intramedullary schwannomas account for 1.1% of all spinal schwannomas. Preoperative diagnosis is best accomplished by thoroughly evaluating clinical and radiological characteristics, accompanied by a high index of suspicion. The authors report a case of C2-3 intramedullary schwannoma in a young male who presented with neck pain and vertigo. The current literature is also reviewed. OBSERVATIONS: The authors reviewed the data of a young male with a 2-month history of neck pain and vertigo. Magnetic resonance imaging of the brain and cervical spine showed an intramedullary mass at C2-3 with a syrinx extending into the cervicomedullary junction. Laminectomy, myelotomy, and microsurgical excision of the mass under intraoperative neurological monitoring (IONM) were done. Postoperative pathology reported the specimen as a schwannoma. LESSONS: Gross-total resection of a schwannoma using IONM is the treatment of choice because of the lesion's benign nature, a better prognosis, and defined cleavage plane. Schwannomas should be included in the differential diagnosis of intramedullary spinal tumors. Because of its progressive nature, early surgery is recommended in symptomatic patients.
RESUMO
BACKGROUND: Estimates of hypertension prevalence in Kenya range from 12.3% to 50.1% nationally. Of those diagnosed, only 1 in 5 were taking medication. OBJECTIVES: This study aims to describe the access to antihypertensive medicines at the household level in 8 counties of Kenya, including factors associated with the location of purchase. METHODS: A household survey was conducted asking individuals with a diagnosis and prescription of antihypertensive medicines about the location of diagnosis and purchase of medicines, the availability of medicines at home, and the costs of medicines per month. A logistic regression model explores the relationship between patient characteristics and the probability that patients bought medicines at a public facility. RESULTS: Of 445 individuals diagnosed and prescribed medicines for hypertension, 20.9% were also diagnosed with another noncommunicable disease, including diabetes or asthma. The majority of study subjects received their diagnosis at a public hospital (67.5%) but the most common place of medicine purchase was a retail pharmacy (33.6%). Some study subjects bought their medicines at a public hospital (21.1%). The most frequent answer for not having medicines at home was that they could not afford their medicines (50.0%). Purchase in the public sector was associated with being less wealthy, having >1 noncommunicable disease, and living in urban areas. CONCLUSIONS: Affordability remains an important barrier to hypertension treatment access in Kenya. Programs to promote access to affordable treatment need to take into account that diagnosis of disease and choice of medicines takes place largely in the public sector, whereas the private sector is the gatekeeper for purchase of medicines.
