Objectives: Pulmonary segmentectomy should be the standard surgical procedure for patients in certain clinical scenarios. However, detecting the intersegmental planes both on the pleural surface and within the lung parenchyma remains a challenge. We developed an intraoperative novel method for distinguishing intersegmental planes of the lung via transbronchial injection of iron sucrose (ClinicalTrials.gov number, NCT03516500).
Methods: We first performed a bronchial injection of iron sucrose to identify the intersegmental plane of the porcine lung. Then, we conducted a prospective study to evaluate the safety and feasibility of the technique in 20 patients who underwent anatomic segmentectomy. Iron sucrose was injected into the bronchus of target pulmonary segments, and the intersegmental planes were divided with electrocautery or stapler.
Results: The median injection of iron sucrose was 90 mL (range, 70-120 mL), and the median time from injection of iron sucrose to demarcation of intersegmental plane was 8 minutes (range, 3-25 minutes). Qualified identification of the intersegmental plane was observed in 17 cases (85%). The intersegmental plane could not be recognized in 3 cases. All patients experienced no complications related to iron sucrose injection or complications of Clavien-Dindo grade 3 or more.
Conclusions: Transbronchial injection of iron sucrose is a simple, safe, and feasible approach to identify the intersegmental plane (NCT03516500).

Introduction: Depression is a prevalent and significant psychological consequence of traumatic brain injury (TBI). Ferroptosis, an iron-dependent form of regulated cell death, exacerbates the neurological damage associated with TBI. This study investigates whether nicorandil, a potassium channel opener with nitrate-like properties known for its antioxidative and neuroprotective effects, can mitigate depression-like behaviors following TBI by modulating ferroptosis.

Introduction: Intravenous iron sucrose (IVIS) is a rapidly acting, safe, and effective treatment for moderate anemia among pregnant women. The effectiveness of IVIS at 6 months post IVIS infusion was unknown. We, therefore, assessed the mean increase in hemoglobin concentration and body iron replenishment status at 6 months after the last dose of IVIS infusion.

Introduction: As the scale of cultivation expands, challenges such as substrate shortages and rising production costs in mushroom cultivation have become increasingly prominent. Fruit tree pruning residue has the potential to serve as an alternative substrate, offering a sustainable solution. This study evaluates the feasibility of incorporating various types of fruit tree pruning residues into cultivation.

Rationale: Intravenous iron is increasingly used to treat iron-deficient anaemia (IDA) in pregnancy. A previous network meta-analysis suggested that intravenous irons have a greater effect on haematological parameters than oral irons; however, the impact on serious pregnancy complications such as postpartum haemorrhage (PPH) or the need for blood transfusion was unclear. Since then, several new randomised controlled trials (RCTs) have been conducted.

Article Synopsis
- Cold stress significantly hinders the growth and development of seedlings in the Tibetan Plateau, but chitosan (CTS) treatment can boost their stress tolerance.
- Under cold stress, CTS improved key photosynthetic metrics and plant health by enhancing soluble sugar, protein levels, and antioxidant content, while also promoting Rubisco activity and reducing starch and sucrose levels.
- The application of CTS mitigated damage to chloroplast structures, fostered better vascular development, and upregulated cold tolerance-related genes, demonstrating its potential in improving plant resilience to cold stress.
