Background: To present the technique of minimally invasive extended thymectomy performed through the subxiphoid-bilateral subcostal video-assisted thoracoscopic surgery (VATS) approach, with double elevation of the sternum for nonthymomatous myasthenia gravis (MG).
Methods: The whole dissection was performed through the 4-7 cm transverse subxiphoid incision with single 10 mm extra-long bariatric laparoscopy ports inserted subcostally to the right and left chest cavities for videothoracoscope and subsequently for chest tubes. The sternum was elevated with two hooks connected to the sternal frame (Rochard bar, Aesculap-Chifa, Nowy Tomysl, Poland). The lower hook was inserted through the subxiphoid incision and the superior hook was inserted percutaneously, after the mediastinal tissue including the major mediastinal vessels were dissected from the inner surface of the sternum. The fatty tissue of the anterior mediastinum and the aorta-pulmonary window was completely removed.
Results: There were 147 patients (62 patients operated on for thymomas, 75 patients for nonthymomatous MG and 10 for rethymectomies) in the period 1.1.2009-30.3.2016. There was no mortality and morbidity. The mean operative time was 109.1 min (range, 75-150 min).
Conclusions: The subxiphoid approach combined with bilateral single port subcostal VATS and double elevation of the sternum enables very extensive thymectomy in case of nonthymomayous MG.

Background: CD3 + CD20 + T cells (T cells) are a subset of lymphocytes in the human body that are associated with inflammation. They originate from T cells interacting with B cells, and their levels are abnormally elevated in individuals with immune disorders, as well as in some cancer patients. The interplay between tumor immunity and inflammation is intricate, yet the specific involvement of T cells in local tumor immunity remains uncertain, with limited research on their subtypes.

Background: Monovalent biologics blocking thymic stromal lymphopoietin or interleukin-13 have been shown to elicit pharmacodynamic responses in asthma following a single dose. Therefore, dual blockade of these cytokines may result in an enhanced response compared to single targeting and has the potential to break efficacy ceilings in asthma. This study assessed the safety and tolerability of lunsekimig, a bispecific NANOBODY molecule that blocks thymic stromal lymphopoietin and interleukin-13, and its effect on Type 2 inflammatory biomarkers and lung function in asthma.

Objective: Asthma is a prevalent global health issue, especially affecting children in numerous countries. Our study aimed to determine the most effective nebulizer type by comparing the effects of mesh nebulizers (MNs) and compressor nebulizers (CNs) on spirometry tests in pediatric asthma attacks.
Methods: The prospective, double-blind, randomized comparative study was conducted with patients aged 7-15 presenting with asthma attacks.

Soil contamination with toxic heavy metals [such as cadmium (Cd)] is becoming a serious global problem due to the rapid development of the social economy. Organic chelating agents such as succinic acid (SA) and oxalic acid (OA) are more efficient, environmentally friendly, and biodegradable compared to inorganic chelating agents and they enhance the solubility, absorption, and stability of metals. To investigate this, we conducted a pot experiment to assess the impact of SA (0.

Objective: Our aim is to review the safety and efficacy of hydroxyurea (HU) on -thalassemia patients.
Methods: Studies that evaluated the safety and efficacy of HU on β-thalassemia patients were searched in Pub-Med, Cochrane Databases, Web of Science, China-Biology-Medicine, CNKI, Embase, VIP, and WanFang data. The proportions of response rate (RR) (50% fall in transfusion need in transfusion-dependent -thalassemia patients, or 1 g/dL elevate in hemoglobin (Hb) levels in transfusion-independent -thalassemia patients) and good RR (transfusion-free in transfusion-dependent -thalassemia patients or 2 g/dL elevate in Hb levels in transfusion-independent β-thalassemia patients) were utilized to evaluate the effect size (ES).
