RESUMO
The current COVID-19 pandemic, caused by SARS-CoV-2, has impacted many facets of hematopoietic cell transplantation (HCT) in both developed and developing countries. Realizing the challenges as a result of this pandemic affecting the daily practice of the HCT centers and the recognition of the variability in practice worldwide, the Worldwide Network for Blood and Marrow Transplantation (WBMT) and the Center for International Blood and Marrow Transplant Research's (CIBMTR) Health Services and International Studies Committee have jointly produced an expert opinion statement as a general guide to deal with certain aspects of HCT, including diagnostics for SARS-CoV-2 in HCT recipient, pre- and post-HCT management, donor issues, medical tourism, and facilities management. During these crucial times, which may last for months or years, the HCT community must reorganize to proceed with transplantation activity in those patients who urgently require it, albeit with extreme caution. This shared knowledge may be of value to the HCT community in the absence of high-quality evidence-based medicine. © 2020 American Society for Transplantation and Cellular Therapy.

Parvovirus B19 virus infection is widespread among humans because of its highly infectious and obstinate nature, with up to 80% of the population testing positive for IgG antibodies against the virus. Pronormoblasts observed in biopsy are the hallmarks of PVB19 infection. In addition, PVB19 affects the skin, heart, brain, joints, and liver and can be diagnosed through antibody detection or DNA detection via PCR. Due to its capsid proteins' high affinity for bone marrow receptors, its main presentation is the suppression of bone marrow functions. It has been shown to affect patients with hemolytic anemia and patients with hematological malignancies, presenting with pure red cell aplasia. The main available effective treatment option is IV immunoglobulins; however, the risk of recurrence remains high after treatment.

SARS-CoV-2 infection induces myocardiopathy in 19% of severe cases, with a mortality rate of up to 51%. The mainstay of treatment is supportive care, steroids, and tocilizumab (anti-IL-6). This is a case of a 43-year-old woman diagnosed with hormone-positive breast cancer with lung metastasis and pulmonary lymphangitis carcinomatosis (PLC). Her baseline cardiac function was within normal limits. She presented to the emergency department with respiratory distress. Chest CT showed multiple bilateral ground-glass opacities consistent with COVID-19 pneumonia and confirmed by COVID-19-PCR nasal swab. Her condition deteriorated, and she was urgently admitted to the intensive care unit with evidence of a cytokine storm. She was started on tocilizumab, dexamethasone, and meropenem. Echocardiogram (echo) showed a severely reduced ejection fraction with severe global hypokinesis. A second dose of tocilizumab was given, and the dexamethasone dose was increased. Fortunately, the patient had significant clinical and biochemical improvement and regained her normal cardiac function. In conclusion, dexamethasone and tocilizumab could be promising aids in treating cardiomyopathy secondary to SARS-CoV-2 infection.
RESUMO
Background: Current guidelines recommend a body mass index (BMI) of 16 kg/m2 as the minimum threshold for lung transplantation, despite mixed evidence on outcomes in underweight patients. The current study aimed to describe survival outcomes of underweight patients who underwent lung transplantation at a single center. Methods: This retrospective observational study included adult lung transplant recipients who underwent transplantation for the first time between March 2010 and March 2022 at King Faisal Specialist Hospital and Research Center and excluded patients with obesity. We defined an underweight status as a BMI <17 kg/m2. Results: Forty-eight of the 202 lung transplant recipients were underweight at the time of surgery. The underweight patients had similar lengths of hospital (p = 0.53) and intensive care unit (p = 0.81) stays compared to other patients. Thirty-three percent of underweight patients had died within 5-year follow-up, compared to 34% of patients who were not underweight. There was no significant difference in mortality risk between underweight patients and patients with normal BMIs in our multivariable Cox regression model (adjusted HR 1.57, 95%CI: 0.77-3.20, p = 0.21). Exploratory analyses revealed that a pre-transplant BMI <13 kg/m2 was associated with a trend towards increased 5-year mortality (adjusted HR 4.00, 95%CI: 0.87-18.35, p = 0.07). Conclusions: Our findings suggest that patients with BMIs of 13-17 kg/m2 may be candidates for lung transplantation. Large multi-center cohort studies are needed to confirm the lower BMI limit for safely transplanting patients.
RESUMO
Autophagy has been of novel interest since it was first demonstrated to have effect in Burkitt's lymphoma. Since that time, the autophagy agents chloroquine and hydroxychloroquine have become the only FDA (Food and Drug Administration)-approved autophagy inhibitors. While not approved for cancer therapy, there are ongoing clinical trials to evaluate their safety and efficacy. Pevonedistat has emerged as a novel inhibitor through the neddylation pathway and is an autophagy activator. This paper summarizes and presents current clinical trials for hydroxychloroquine (HCQ), chloroquine (CQ), and Pevonedistat for the clinician.

BACKGROUND: Cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors have been a significant breakthrough in the management of hormone receptor-positive, HER2-negative metastatic breast cancer based on the results of several large phase III randomized trials. The most common reported toxicity is myelosuppression due to disease such as leukopenia, neutropenia, and thrombocytopenia. Other toxicities associated with CDK 4/6 inhibitors include mucositis, fatigue, gastrointestinal side effects, hepatic toxicities, and QTc prolongation. Despite a good toxicity profile in pivotal studies, the increased rates of use in clinical practice may show less prevalent but lethal toxicity such as lung injury. CASE PRESENTATION: Here, we describe a female patient with metastatic hormone receptor-positive/human epidermal growth factor 2-negative breast cancer who developed lung toxicity while on ribociclib. DISCUSSION: Lung injury is a possible side effect of CDK 4/6 inhibitors and there is an increasing need to understand the management of this side effect.
RESUMO
Introduction: Due to the complex nature of cancer cases, it is imperative that the involved healthcare providers coordinate the patients care plan in union to reach the best possible outcome in the smoothest and fastest manner. This is what multidisciplinary tumor board (MTB) meetings strive to achieve. Conducting regular MTB meetings requires significant investment of time and finances. It is thus vital to assess the empirical benefits of such practice. Methods: A meta-analysis was conducted to evaluate the literature regarding the impact of MTB meetings on patient 5-year survival. Relevant studies were identified by searching Ovid MEDLINE and Embase databases from January 1995 to July 2019. Studies were included if they assessed 5-year survival in cases discussed in MTB meetings and used a comparison group and/or a pretest and posttest design. Results: Five articles met the study's inclusion criteria. Quality of studies was affected by selection bias and the use of historic cohorts. The results showed significantly improved 5-year survival in the MTB group compared with the non-MTB groups (odds ratio for 5-year death rate of 0.59, CI 0.45-0.78, p < 0.001). Conclusion: This meta-analysis showed that cancer MTB meetings have a significant impact on patients' 5-year survival. This could be because of several reasons, such as less time to treatment initiation, better adherence to guidelines, higher numbers of investigational imaging, lesser surgical complications, and recurrence rates. Future prospective studies are needed to further delineate reasons for improvement of outcome to enhance the benefits of this approach.
RESUMO
PURPOSE: This study examined the effect of permissive underfeeding compared to target feeding and intensive insulin therapy (IIT) compared to conventional insulin therapy (CIT) on the inflammatory mediators monocyte chemoattractant protein 1 (MCP-1), soluble intercellular adhesion molecule 1 (sICAM-1), and tissue factor (TF) in critically ill patients. METHODOLOGY: This was a substudy of a 2 × 2 factorial design randomized controlled trial in which intensive care unit (ICU) patients were randomized into permissive underfeeding compared to target feeding groups and into IIT compared to CIT groups (ISRCTN96294863). In this substudy, we included 91 patients with almost equal numbers across randomization groups. Blood samples were collected at baseline and at days 3, 5, and 7 of an ICU stay. Linear mixed models were used to assess the differences in MCP-1, sICAM-1, and TF across randomization groups over time. RESULTS: Baseline characteristics were balanced across randomization groups. Daily caloric intake was significantly higher in the target feeding than in the permissive underfeeding groups (P-value < 0.01), and the daily insulin dose was significantly higher in the IIT than in the CIT groups (P-value < 0.01). MCP-1, sICAM-1, and TF did not show any significant difference between the randomization groups, while there was a time effect for MCP-1. Baseline sequential organ failure assessment (SOFA) score and platelets had a significant effect on sICAM-1 (P-value < 0.01). For TF, there was a significant association with age (P-value < 0.01). CONCLUSIONS: Although it has been previously demonstrated that insulin inhibits MCP-1, sICAM-1 in critically ill patients, and TF in non-critically ill patients, our study demonstrated that IIT in critically ill patients did not affect these inflammatory mediators. Similarly, caloric intake had a negligible effect on the inflammatory mediators studied.

Tumour board contributes to providing better patient care by using a multidisciplinary team approach. In the efforts of evaluating the performance of the gastrointestinal tumour board at our institution, it was difficult to assess past performance due to lack of proper use of standardised documentation tool. This project aimed at improving adherence to the documentation tool and its recommendations in order to obtain performance measures for the tumour board. A multidisciplinary team and a plan were developed to improve documentation. Four rapid improvement cycles, Plan-Do-Study-Act (PDSA) cycles, were conducted. The first cycle focused on updating the case discussion summary form (CDSF) based on experts' input and previous identified deficiencies to enhance documentation and improve performance. The second PDSA cycle aimed at incorporating the CDSF into the electronic medical records system and assessing its functionality. The third cycle was to orient and train staff on using the form and launching it. The fourth PDSA cycle aimed at assessing the ability to obtain tumour board performance measures. Adherence to completion of the CDSF improved from 82% (baseline) to 94% after the fourth PDSA cycle. Over 104 consecutive cases discussed in the tumour board between January and July 2016 and 76 cases discussed in 2015, results were as follows: adherence to National Comprehensive Cancer Network guidelines in 2016 was observed in 141 (95%) recommendations, while it was observed in 90 (92%) recommendations in 2015. Changes in the management plans were observed in 37 (36%) cases in 2016 and in 6 (8%) cases in 2015. Regarding tumour board recommendations, 87% were done within 3 months of tumour board discussion in 2016, while 69% were done in 2015. Implementing electronic standardised documentation tool improved communication among the team and enabled getting accurate data about performance measures of the tumour board with positive impact on healthcare process and outcomes.
RESUMO
PURPOSE: As the burden of cancer on the population and the health care system continues to increase with more complicated treatment options, the need for multidisciplinary teams to be as efficient as possible becomes more vital. Our study aimed to evaluate the consistency of GI Tumor Board (GI TB) recommendations with international guidelines, the adherence of physicians involved in patient care to TB recommendations, and the impact on the management of patients. METHODS: A prospective cohort study was conducted from January to June 2016 at our institution, which is a major tertiary hospital that provides comprehensive cancer care. All cases presented at the GI TB during this period were included. Data regarding adherence to National Comprehensive Cancer Network guidelines, adherence to TB recommendations, and changes made to the management of patients were collected weekly from the GI TB in a data collection form. RESULTS: Of the 104 patients included, 57 (55%) were males and the median age was 58 (16 to 85) years. Colorectal cancer was the most common diagnosis, in 65 patients (63%). Nearly one-half of cases (45%) were stage IV cancers. Starting new treatment was recommended for 72 patients (69%). Further investigations were requested for 15 patients (14%). For imaging, 24 recommendations (23%) were made. Adherence to National Comprehensive Cancer Network guidelines was observed in 97% of total recommendations. New findings were found in pathology (11%), radiology (13%), and staging (4%). Management plans were changed in 37 cases (36%). Over a 3-month period after presentation to the GI TB, most of the recommendations (87%) were performed. CONCLUSION: A multidisciplinary tumor board enhances the adherence to guidelines and has an impact on patient management in approximately one-third of patients. Among physicians, adherence to recommendations of the TB was high.
