The White Blood Cell Count in Laboring Women at Term Is Associated with Neonatal Macrosomia.

Background: Fetal weight estimation at term is a challenging clinical task.

Objectives: To evaluate the association between peripheral white blood cell (WBC) count of the laboring women and neonatal birth weight (BW) for term uncomplicated pregnancies.

Methods: We conducted a single-center, retrospective cohort study (2006-2021) of women admitted in the first stage of labor or planned cesarean delivery.

The evolving landscape of COVID-19 and post-COVID condition in patients with chronic lymphocytic leukemia: A study by ERIC, the European research initiative on CLL.

In this retrospective international multicenter study, we describe the clinical characteristics and outcomes of patients with chronic lymphocytic leukemia (CLL) and related disorders (small lymphocytic lymphoma and high-count monoclonal B lymphocytosis) infected by SARS-CoV-2, including the development of post-COVID condition. Data from 1540 patients with CLL infected by SARS-CoV-2 from January 2020 to May 2022 were included in the analysis and assigned to four phases based on cases disposition and SARS-CoV-2 variants emergence. Post-COVID condition was defined according to the WHO criteria.

COVID-19 severity and mortality in patients with CLL: an update of the international ERIC and Campus CLL study.

Patients with chronic lymphocytic leukemia (CLL) may be more susceptible to Coronavirus disease 2019 (COVID-19) due to age, disease, and treatment-related immunosuppression. We aimed to assess risk factors of outcome and elucidate the impact of CLL-directed treatments on the course of COVID-19. We conducted a retrospective, international study, collectively including 941 patients with CLL and confirmed COVID-19.

[FDG PET/CT FOR TREATMENT RESPONSE ASSESSMENT IN CANCER].

FDG PET/CT (fluorodeoxyglucose (FDG)-positron emission tomography (PET) computed tomography (CT)) imaging reflects functional-metabolic changes occurring within the malignant process in response to therapy. Since these changes usually precede anatomic alterations, this imaging technique is highly valuable in assessing response during and after therapy and is superior to CT. FDG PET/CT following initiation of cancer therapy has a prognostic value, predicting progression free survival and overall survival.

Incidence, risk factors, and recognition of pseudohyperkalemia in patients with chronic lymphocytic leukemia.

Pseudohyperkalemia, a false elevation of potassium level in vitro, can be observed in chronic lymphocytic leukemia (CLL) patients due to fragility of leukocytes along with a high leukocyte count. This retrospective, observational study included all patients diagnosed with CLL at our hospital who had at least one leukocyte count ≥ 50.0 × 10/L during the years 2008-2018.

The maternal leukocyte count at admission for labor is indicative of early maternal postpartum infectious morbidity and adverse neonatal outcome.

Objectives: Investigate the association between maternal leukocyte count at admission for labor and postpartum infectious maternal morbidity (PPIM) following vaginal delivery.

Study Design: Retrospective cohort study, 2005-2017. Afebrile women, term, singleton, vaginal delivery included.

A patient with Gaucher disease and plasma cell dyscrasia: bidirectional impact.

Patients with Gaucher disease (GD), a rare autosomal recessive glycosphingolipid storage disease, commonly present to hematologists with unexplained splenomegaly, thrombocytopenia, anemia, and bone symptoms. Patients with GD may develop other manifestations, such as autoimmune thrombocytopenia, monoclonal gammopathy, multiple myeloma, or, even more rarely, other hematological malignancies; sometimes they are first diagnosed during an assessment of those disorders. Although the diagnosis and management of patients with GD have significantly evolved over the last 30 years, some patients remain poor responders to GD-specific therapy, needing novel and investigational therapies.

Frontline treatment with the combination obinutuzumab ± chlorambucil for chronic lymphocytic leukemia outside clinical trials: Results of a multinational, multicenter study by ERIC and the Israeli CLL study group.

In recent years, considerable progress has been made in frontline therapy for elderly/physically unfit patients with CLL. The combination of obinutuzumab and chlorambucil (O-Clb) has been shown to prolong progression free survival (PFS, median PFS-31.5 months) and overall survival (OS) compared to chlorambucil alone.

Gaucher disease, myelodysplastic syndrome and ICUS.

Gaucher disease is an inherited lysosomal storage disease commonly associated with hepatosplenomegaly and cytopenias. Progressive cytopenias may be interpreted as an indication of advanced disease and suggest the need to start Gaucher disease specific treatment. As bone marrow evaluation is not routinely performed in Gaucher disease, other causes of cytopenias such as myelodysplastic syndrome a stem cell disorder may be missed.

Ibrutinib-associated invasive fungal diseases in patients with chronic lymphocytic leukaemia and non-Hodgkin lymphoma: An observational study.

Background: Invasive fungal diseases (IFD) are life-threatening infections most commonly diagnosed in acute leukaemia patients with prolonged neutropenia and are uncommonly diagnosed in patients with lymphoproliferative diseases.

Objectives: Following the initial report of aspergillosis diagnosed shortly after beginning ibrutinib for chronic lymphocytic leukaemia, a survey was developed to seek additional cases of IFD during ibrutinib treatment.

Methods: Local and international physicians and groups were approached for relevant cases.

A new risk model to predict time to first treatment in chronic lymphocytic leukemia based on heavy chain immunoparesis and summated free light chain.

Background: Chronic lymphocytic leukemia (CLL) is frequently accompanied by immune dysregulation.

Aims: In this multicenter prospective study, we investigated whether heavy + light chains (HLC: IgGκ, IgGλ, IgAκ, IgAκ, IgMκ, IgMλ) and IgG subclasses (IgG1, IgG2, IgG3, and IgG4) could be used as novel prognostic markers of immunoparesis in 105 treatment-naïve patients with CLL.

Results: Heavy + light chains immunoparesis of ≥1, ≥2, and ≥3 isotypes was evident in 74 (70%), 58 (55%), and 36 (34%) patients, respectively.

Primary peg-filgrastim prophylaxis versus filgrastim given "on demand" for neutropenia during therapy with cladribine for hairy cell leukemia.

Background: Major advances in the treatment of patients with hairy cell leukemia (HCL) have been made following the introduction of purine analogues. The major significant short-term toxicity of cladribine therapy are neutropenia and neutropenic fever (NF) which may be life-threatening.

Aim: In this retrospective study, we compared the incidence and duration of neutropenia and hospitalization in patients with HCL treated with cladribine followed by peg-filgrastim as primary prophylaxis versus daily filgrastim given "on demand" according to absolute neutrophil count (ANC).

Low-dose fludarabine and cyclophosphamide combined with standard dose rituximab (LD-FCR) is an effective and safe regimen for elderly untreated patients with chronic lymphocytic leukemia: The Israeli CLL study group experience.

Chronic lymphocytic leukemia (CLL) is a disease of elderly patients. The fludarabine, cyclophosphamide, and rituximab (FCR) regimen is considered the treatment of choice for young fit patients with CLL; however, this combination is toxic for older patients. At the time this study was first planned and initiated, there was no standard chemo-immunotherapy regimen regarded as standard therapy for the less fit elderly patient with CLL.

Hairy Cell Leukemia: Retrospective Analysis of Demographic Data and Outcome of 203 Patients from 12 Medical Centers in Israel.

Background/aim: In this retrospective study, we summarized the national Israeli experience with hairy cell leukemia (HCL) in a large cohort of patients with a long follow-up.

Patients And Methods: Demographic data, and relevant laboratory and clinical parameters were analyzed, emphasizing the outcome after first-line treatment with cladribine.

Results: Data on 203 patients was collected from 12 medical centers during 1985-2015.

Outcomes of second-line treatment after fludarabine cyclophosphamide and rituximab in patients with chronic lymphocytic leukemia outside clinical trials.

Objective: To evaluate disease characteristics and long-term outcomes in patients requiring second-line treatment following fludarabine, cyclophosphamide, and rituximab (FCR), for relapsed/refractory disease (R/R), or following discontinuation due to toxicities.

Method: A retrospective analysis of 126 chronic lymphocytic leukemia patients treated with frontline FCR: 63 received second-line treatment (41 relapsed, nine refractory [SD/PD], 13 prior toxicity). Time to next treatment (TTNT) was calculated from beginning FCR to initiation of second-line therapy.

Bone loss and hematological malignancies in adults: a pilot study.

Purpose: Bone loss-osteopenia and osteoporosis-is a recognized consequence of solid tumors in adults, of pediatric hematological malignancies, and of the treatment for these diseases, but little research has been published on the adverse effects of hematological malignancies on the bone in adults. The aim of this study is to identify hematological diseases that are associated with the highest prevalence and severity of osteoporosis.

Methods: We evaluated DXA (dual-energy X-ray absorptiometry) in a cross-section of 181 adult patients with hematological neoplasms, excluding multiple myeloma.

Persistently low lymphocyte counts after FCR therapy for chronic lymphocytic leukemia are associated with longer overall survival.

Decreased absolute lymphocyte counts (ALCs) following frontline therapy for chronic lymphocytic leukemia may be associated with disease control, even in patients without evidence of minimal residual disease. We studied the prognostic significance of ALCs during the first year following treatment with fludarabine, cyclophosphamide, and rituximab (FCR). We evaluated 99 patients who achieved a partial response without lymphocytosis (<4.

Modification of initial therapy in early and advanced Hodgkin lymphoma, based on interim PET/CT is beneficial: a prospective multicentre trial of 355 patients.

This multicentre study evaluated 5-year progression-free (PFS) and overall survival (OS) in early and advanced Hodgkin lymphoma (HL), where therapy was individualized based on initial prognostic factors and positron emission tomography-computed tomography performed after two cycles (PET-2). Between September 2006 and August 2013, 359 patients aged 18-60 years, were recruited in nine Israeli centres. Early-HL patients initially received ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) ×2.
