Mesenchymal stroma/stem cells: Haematologists' friend or foe?

Mesenchymal stromal cells (MSCs) are non-haematopoietic cells found in fetal and adult organs, that play important roles in tissue repair, inflammation and immune modulation. MSCs residing in the bone marrow interact closely with haematopoietic cells and comprise an important component of the microenvironment supporting haematopoiesis, in both health and disease states. Since their identification in 1970, basic scientific and preclinical research efforts have shed light on the role of MSCs in the regulation of haematopoiesis and evoked interest in their clinical application in haematopoietic stem cell transplantation (HSCT) and malignant haematology.

Determinants of Response to Cardiac Resynchronization Therapy.

Cardiac resynchronization therapy (CRT) is a well-established treatment modality for ambulatory patients with heart failure (HF) who have prolonged QRS, left bundle branch block, reduced left ventricular (LV) ejection fraction, and New York Heart Association class II-IV. CRT has been shown to induce reverse LV remodeling and improve HF symptoms and clinical outcomes. About one-third of CRT recipients are considered non-responders.

Biallelic Variants in the Ectonucleotidase ENTPD1 Cause a Complex Neurodevelopmental Disorder with Intellectual Disability, Distinct White Matter Abnormalities, and Spastic Paraplegia.

Objective: Human genomics established that pathogenic variation in diverse genes can underlie a single disorder. For example, hereditary spastic paraplegia is associated with >80 genes, with frequently only few affected individuals described for each gene. Herein, we characterize a large cohort of individuals with biallelic variation in ENTPD1, a gene previously linked to spastic paraplegia 64 (Mendelian Inheritance in Man # 615683).

The time is now: addressing the need for training in maternal critical care medicine.

Amongst many high-income countries, indirect medical conditions (e.g. cardiovascular disease, sepsis) now account for the majority of maternal deaths.

Sentinel Lymph Node Identification in Cutaneous Head & Neck Cancer - Lymphoscintigraphy Late Phase.

Objective: Sentinel node (SN) biopsy following lymphoscintography is recommended for high-risk cutaneous malignancies. Herein, we investigate different lymphoscintography phases, focusing on the importance of the late static phase and the resultant discovery of distal echelon solitary positive sentinel nodes that would otherwise have been overlooked.

Methods: In this retrospective cohort study, conducted in a tertiary referral medical center, we assessed SN localization and time from tracer injection to SN identification on lymphoscintigraphy.

Performance of non-invasive stroke volume variation during passive leg raising as a predictor of hypotension following induction of spinal anesthesia for elective cesarean delivery: a single cohort study.

Background: Spinal anesthesia for cesarean delivery is accompanied by hypotension in up to 70% of cases. To date, there is no gold standard for predicting hypotension after spinal anesthesia for cesarean delivery. The Clearsight™ device is a non-invasive system that uses a digital cuff to calculate stroke volume.

Thyroid Hormones and Morphological Features of Primary Breast Cancer.

Background/aim: Many experimental studies have suggested the importance of thyroid hormones in breast cancer (BC) morphogenesis. The aim of this study was to evaluate the association of thyroid hormone levels in serum of patients with primary BC with morphological presentations of the disease in pathological specimens and prognosis.

Patients And Methods: We measured the serum levels of thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4), along with serum thymidine kinase 1 activity and examined their relation to pathological features and prognosis of 158 patients with primary BC.

Changes in communication of end-of-life decisions in European ICUs from 1999 to 2016 (Ethicus-2) - a prospective observational study.

Purpose: We investigated changes in communication practice about end-of-life decisions in European ICUs over 16 years.

Materials And Methods: This prospectively planned secondary analysis of two observational studies in 22 European ICUs in 1999-2000 (Ethicus-1) and 2015-16 (Ethicus-2) included consecutive patients who died or with limitation of life-sustaining therapy. ICUs were grouped into North, Central and South European regions.

Don't forget arterial thrombosis in patients with COVID-19: A case series.

Introduction: The acute disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS COV-2) is accompanied by a hypercoagulable state. Multiple publications have described the venous thromboembolic events associated with coronavirus disease 2019 (COVID-19) but arterial thromboembolic events have yet to be described.

Cases Description: We describe five COVID-19 patients that developed severe morbidity as a result of occlusive arterial thromboembolic events occurring despite treatment with low molecular weight heparin.

From the "what" to the "how": Teaching integrative medicine-related skills to medical students during COVID-19.

Objective: To examine the impact of an integrative medicine (IM) course on self-perceived IM-related communication and research skills.

Methods: A 3-day mandatory "hybrid" (online and in-person) IM course was held within COVID-19 restrictions for 161 pre-clerkship medical students, with workshops facilitated by mentor healthcare professionals (IM and non-IM) and student-directed tasks. Self-perceived levels of 6 IM-related skills were scored (from 1 to 5) for history-taking; communicating with patients with "alternative" health-beliefs; referral to IM consultations; assessing risks/benefits; and working with non-medical IM practitioners.

Allogeneic hematopoietic cell transplantation for acute myeloid leukemia in first complete remission after 5-azacitidine and venetoclax: a multicenter retrospective study.

The combination of hypomethylating agents and venetoclax has revolutionized the therapeutic landscape of acute myeloid leukemia (AML), especially for patients previously deemed unfit for curative-intent treatment. Some of these patients undergo allogeneic hematopoietic cell transplant (alloHCT); yet, there are scarce data regarding transplantation outcomes. We conducted a multicenter nationwide retrospective cohort study, including patients with AML who underwent alloHCT in CR1 after frontline treatment with azacitidine plus venetoclax only (aza-ven group).

Management of the patient with the open abdomen.

Purpose Of Review: The aim of this study was to outline the management of the patient with the open abdomen.

Recent Findings: An open abdomen approach is used after damage control laparotomy, to decrease risk for postsurgery intra-abdominal hypertension, if reoperation is likely and after primary abdominal decompression.Temporary abdominal wall closure without negative pressure is associated with higher rates of intra-abdominal infection and evisceration.

The relationship between cannabis use and IVF outcome-a cohort study.

Background: The effects of cannabis use on male and female reproduction have been the focus of scientific research for decades. Although initial studies raised concerns, more recent studies were reassuring. Considering the recent legalization of recreational use of cannabis in Canada, we sought to analyze IVF outcomes among users and non-users in a single IVF center.

From the bench to practice - Field integration of community-based services for older citizens with different levels of functional limitation across European Regions.

The meeting of the European Innovation Partnership on Active and Healthy Ageing (EIPonAHA) action group A3 together with members of the Reference site collaborative network (RSCN) in December 2019 in Rome focused on integration of evidence-based approaches on health and care delivery for older citizens at different levels of needs with expertise coming from stakeholder across Europe. It was the final aim of the group to co-create culturally sensitive pathways and facilitate co-ownership for further implementation of the pathways in different care systems across Europe. The study design is a mixed method approach.

Methods: The course curriculum addressed effectiveness and safety of IM practices highlighting supportive and palliative care, demonstrated the work of integrative physicians (IPs) in designing patient-tailored treatments and taught practical skills in communication regarding IM. Group discussions were conducted via Zoom with 32 physicians, healthcare practitioners and IM practitioners working in integrative academic, community and hospital-based settings, in Israel, Italy, UK and Germany.

Explant Modeling of the Immune Environment of Head and Neck Cancer.

Patients exhibit distinct responses to immunotherapies that are thought to be linked to their tumor immune environment. However, wide variations in outcomes are also observed in patients with matched baseline tumor environments, indicating that the biological response to treatment is not currently predictable using a snapshot analysis. To investigate the relationship between the immune environment of tumors and the biological response to immunotherapies, we characterized four murine head and neck squamous cell carcinoma (HNSCC) models on two genetic backgrounds.

A platform for locoregional T-cell immunotherapy to control HNSCC recurrence following tumor resection.

Surgical resection of head and neck squamous-cell carcinoma (HNSCC) is associated with high rates of local and distant recurrence, partially mitigated by adjuvant therapy. A pre-existing immune response in the patient's tumor is associated with better outcomes following treatment with conventional therapies, but improved options are needed for patients with poor anti-tumor immunity. We hypothesized that local delivery of tumor antigen-specific T-cells into the resection cavity following surgery would direct T-cells to residual antigens in the margins and draining lymphatics and present a platform for T-cell-targeted immunotherapy.
