High-resolution spatial prediction of anemia risk among children aged 6 to 59 months in low- and middle-income countries
Anemia, a severe condition among children associated with adverse health effects such as impaired growth, limited physical and cognitive development, and increased mortality risk, remains widespread, particularly in low- and middle-income countries. This study combines Demographic and Health Surveys data with remotely sensed climate, demographic, environmental, and geo-spatial information, creating a data set comprising about 750,000 observations on childhood anemia from 37 countries. It is used to provide high-resolution spatio-temporal estimates of all forms of childhood anemia between 2005 and 2020.
Improved prognosis of advanced-stage extranodal NK/T-cell lymphoma: results of the NKEA-Next study
A retrospective study of extranodal natural killer/T-cell lymphoma (ENKL) patients diagnosed between 2014 and 2021 in Japan was conducted. Among 351 patients with sufficient data, 116 (33%) were in the advanced stage (5 in stage III and 111 in stage IV) at diagnosis, and were further analyzed. The median age was 60 years (range: 19–90), and 68 (59%) were male. Ninety-four (85%) of stage IV patients had two or more extranodal involvements. The most common first-line regimen was SMILE (steroid, methotrexate, ifosfamide, L-asparaginase, and etoposide; 52%). The 2-year overall survival (OS) for all patients was 38.5%, which was significantly improved after 2017 (25.2% for 2014–2017 vs. 50.7% for 2018–2021; P = 0.008). Patients treated with SMILE showed better OS than those treated with DeVIC or CHOP (2y-OS: 57.1%, 35.8%, and 0%, respectively; P < 0.001). The prognosis was significantly better in patients who received hematopoietic stem cell transplantation (HSCT) than in those who did not (2-year OS: 68.3% vs. 17.6%, P < 0.001). Multivariate analysis showed SMILE and HSCT were significant factors for OS. In conclusion, the prognosis of advanced-stage ENKL has improved in recent years. The L-asparaginase-containing chemotherapy and subsequent HSCT is considered the recommended strategy.
Autologous haematopoietic stem cell transplantation for treatment of multiple sclerosis and neuromyelitis optica spectrum disorder — recommendations from ECTRIMS and the EBMT
Autologous haematopoietic stem cell transplantation (AHSCT) is a treatment option for relapsing forms of multiple sclerosis (MS) that are refractory to disease-modifying therapy (DMT). AHSCT after failure of high-efficacy DMT in aggressive forms of relapsing–remitting MS is a generally accepted indication, yet the optimal placement of this approach in the treatment sequence is not universally agreed upon. Uncertainties also remain with respect to other indications, such as in rapidly evolving, severe, treatment-naive MS, progressive MS, and neuromyelitis optica spectrum disorder (NMOSD). Furthermore, treatment and monitoring protocols, rehabilitation and other supportive care before and after AHSCT need to be optimized. To address these issues, we convened a European Committee for Treatment and Research in Multiple Sclerosis Focused Workshop in partnership with the European Society for Blood and Marrow Transplantation Autoimmune Diseases Working Party, in which evidence and key questions were presented and discussed by experts in these diseases and in AHSCT. Based on the workshop output and subsequent written interactions, this Consensus Statement provides practical guidance and recommendations on the use of AHSCT in MS and NMOSD. Recommendations are based on the available evidence, or on consensus when evidence was insufficient. We summarize the key evidence, report the final recommendations, and identify areas for further research.
Clinical practice recommendations for the diagnosis and management of X-linked hypophosphataemia
X-linked hypophosphataemia (XLH) is a rare metabolic bone disorder caused by pathogenic variants in the PHEX gene, which is predominantly expressed in osteoblasts, osteocytes and odontoblasts. XLH is characterized by increased synthesis of the bone-derived phosphaturic hormone fibroblast growth factor 23 (FGF23), which results in renal phosphate wasting with consecutive hypophosphataemia, rickets, osteomalacia, disproportionate short stature, oral manifestations, pseudofractures, craniosynostosis, enthesopathies and osteoarthritis. Patients with XLH should be provided with multidisciplinary care organized by a metabolic bone expert. Historically, these patients were treated with frequent doses of oral phosphate supplements and active vitamin D, which was of limited efficiency and associated with adverse effects. However, the management of XLH has evolved in the past few years owing to the availability of burosumab, a fully humanized monoclonal antibody that neutralizes circulating FGF23. Here, we provide updated clinical practice recommendations for the diagnosis and management of XLH to improve outcomes and quality of life in these patients.
Evaluation of gecacitinib vs hydroxyurea in patients with intermediate-2 or high-risk myelofibrosis: final analysis results from a randomized phase 3 study
To compare the efficacy and safety of gecacitinib (also known as jaktinib) with hydroxyurea (HU) in treating myelofibrosis (MF) patients. In this multicenter, randomized phase 3 trial (ZGJAK016), intermediate- or high-risk primarily JAK inhibitor naïve MF patients were assigned in a 2:1 ratio to receive either gecacitinib (100 mg twice a day, BID) or HU (500 mg BID). The primary endpoint was the proportion of patients with ≥35% reduction in spleen volume (SVR35) from baseline at week 24. Secondary endpoints included the best spleen response rate, the proportion of patients with a ≥50% reduction in total symptom score (TSS50), anemia improvement, and safety profile. At 24 weeks, the SVR35 was reached by 64.8% of patients on gecacitinib (46/71), compared to 26.5% on HU (9/34), P = 0.0002. The best spleen response rates were also superior for gecacitinib at 81.7%, vs 32.4% for HU, P < 0.0001. The TSS50 rates were 62.0% for gecacitinib- and 50% for HU-treated patients. Among non-transfusion-dependent patients with baseline hemoglobin (HGB) ≤ 100 g/L, 31.0% (13/42) in the gecacitinib group showed a ≥20 g/L increase in HGB, compared to 15.0% (3/20) in HU group. The common grade ≥ 3 treatment-emergent adverse events (TEAEs), including anemia (26.8% vs 44.1%), thrombocytopenia (15.5% vs 32.4%), leukopenia (2.8% vs 20.6%), and neutropenia (1.4% vs 20.6%), were less frequent with gecacitinib than HU. Treatment discontinuation due to TEAEs was lower in gecacitinib (7.0%) compared to HU (11.8%). Gecacitinib demonstrates superior efficacy and a more favorable safety profile compared to HU, making it a promising treatment option for managing MF, particularly in patients with anemia (This trial was registered with ClinicalTrials.gov, (NCT04617028)).
