Literature reports suggest that iron-deficiency may contribute to the development or intensification of the condition termed generally "immunodeficiency". In the available literature no reports were found on a precise evaluation of the functions of peripheral blood neutrophils in iron deficiency anaemia. The purpose of the presented study was: 1) estimation of the adherence of neutrophils from peripheral blood to fibres, 2) evaluation of the indices of spontaneous and latex-stimulated NBT reduction by the neutrophils, and 3) the test of spontaneous migration of peripheral blood leucocytes. The study of 20 patients with iron-deficiency anaemia, with counts of total leucocytes and absolute neutrophil count in peripheral blood showed increased adherence of the neutrophils and reduced spontaneous migration of leucocytes in the 3-hour test, but no changes in the test of spontaneous and latex-stimulated NBT reduction. In the discussion an interpretation of the observed abnormalities in the studied biological functions of the neutrophils in patients with iron-deficiency anaemia is tentatively put forward, stressing that in this anaemia despite absence of changes in the counts of peripheral blood neutrophils, spontaneous migration of peripheral blood neutrophils in the 3-hour test is reduced, perhaps as a result of increased adherence of neutrophils.

Objective: To investigate the effects of modified twin-block appliances (MTBA) on obstructive sleep apnea (OSA) and mandibular retrognathia and the changes in the upper airway, hyoid bone position, and hypoxia-related inflammatory marker levels in children with OSA.
Methods: This study included children with OSA and mandibular retrognathia and those with class I without mandibular retrognathia (n = 35 each). The experimental group comprised children with OSA and mandibular retrognathia managed using MTBA.

Background: Therapeutic antibodies for the treatment of neurological disease show great potential, but their applications are rather limited due to limited brain exposure. The most well-studied approach to enhance brain influx of protein therapeutics, is receptor-mediated transcytosis (RMT) by targeting nutrient receptors to shuttle protein therapeutics over the blood-brain barrier (BBB) along with their endogenous cargos. While higher brain exposure is achieved with RMT, the timeframe is short due to rather fast brain clearance.

Background: Multiple studies have demonstrated that the abundance and functionality of γδ T cells are favorable prognostic indicators for prolonged survival in cancer patients. However, the association between the immunophenotype of circulating γδ T cells and the therapeutic response in NSCLC patients undergoing chemotherapy or targeted therapy remains unclear.
Methods: Patients with EGFR wild-type (EGFR-WT) or mutant (EGFR-Mut) non-small cell lung cancer (NSCLC), diagnosed between January 2020 and January 2024, were included in this study.

Objective: To analyze the characteristics of pulmonary nodules (PNs) and related influencing factors in patients with type 2 diabetes mellitus (T2DM).
Methods: Retrospectively analyzed the clinical and biochemical characteristics of 224 patients with PNs and 488 patients with non-PNs in patients with T2DM, and compared the clinical data of 72 patients with large nodules (≥ 5 mm) and 152 patients with small nodules (< 5 mm) in the pulmonary nodules (PNs) group.
Results: Compared to the non-PNs group, the PNs Patients in the group had a longer duration of diabetes, higher age, serum creatinine (SCR), blood urea nitrogen (BUN) and the lower albumin (ALB) and body mass index (BMI); women, diabetic retinopathy (DR), diabetic peripheral neuropathy (DPN), and estimated glomerular filtration rate (eGFR) < 60 ml/min1.

Department of Intensive Care Medicine, Army Medical Center of PLA, No. 10 Changjiang Road, Yuzhong District, Chongqing, 400010, People's Republic of China.
Background: Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) is a form of thrombotic microangiopathy (TMA) caused by uncontrolled activation of the complement system during pregnancy or the postpartum period. In the intensive care unit, aHUS must be differentiated from sepsis-related multiple organ dysfunction, thrombotic thrombocytopenic purpura (TTP), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. Early recognition of aHUS is critical for effective treatment and improved prognosis.
