To describe the efficacy and safety of intense pulsed light (IPL) applied directly on the eyelids of patients with Meibomian gland dysfunction (MGD) without corneal shield protector. Observational retrospective single centre study where patients underwent 3 treatment sessions of IPL with 2 weeks of interval. The IPL was carried out with Lumenis OPT M22 with a double pass technique of 12 impacts on the infraorbital/lower eyelid region with the 15 × 35 mm guide light (step 1) and a double pass technique of 3 impacts over the upper eyelids with the 8 × 15 mm guide light (step 2). The follow up was conducted through Oculus Keratograph 5 M. 30 patients were enrolled in the study. Although there were no significant differences (p > 0.05), non-invasive tear break-up time, ocular redness, and OSDI questionnaire improved during the 3 IPL sessions. A significant improvement (p = 0.024) in the percentage of meibomian gland loss was also observed. Regarding tear meniscus, it was found similar measurements before and after treatment. No serious adverse effects were reported during the procedure or in subsequent follow-up. Preliminary results suggest that IPL therapy applied directly on the eyelids without corneal shield could be safe and effective in the treatment of MGD.

Department of Gastroenterology, The Affiliated People's Hospital of Ningbo University, Ningbo, China.
Rationale: Gastric antral vascular ectasia (GAVE) is a rare acquired lesion characterized by vascular dilation in the gastric antrum, frequently results in occult or overt gastrointestinal bleeding. Endoscopic intervention remains the cornerstone of therapy. Argon plasma coagulation was previously considered a first treatment option.

Department of Hepatobiliary Surgery, The Third Central Hospital of Tianjin, Tianjin, China.
Background: In patients with advanced hepatocellular carcinoma (HCC) following sorafenib failure, regorafenib has been used as an initial second-line drug. It is unclear the real efficacy and safety of sorafenib-regorafenib sequential therapy compared to placebo or other treatment (cabozantinib or nivolumab or placebo) in advanced HCC.
Methods: Four electronic databases (PubMed, Embase, Web of Science, and Ovid) were systematically searched for eligible articles from their inception to July, 2024.
A novel posterior decompression technique (anterior sliding decompression osteotomy) for beak-type ossification of the posterior longitudinal ligament in the thoracic spine.

3Department of Orthopedic Surgery, Haeundae Bumin Hospital, Busan, South Korea.
Objective: Conventional decompression surgery for beak-type ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine, whether approached anteriorly or posteriorly, poses several challenges, including technical complexity, cerebrospinal fluid leakage, incomplete decompression, and potential neurological deterioration. Therefore, the authors introduce a novel technique, anterior sliding decompression osteotomy (ASDO), for thoracic myelopathy caused by OPLL and evaluate the efficacy and safety of this technique.
Methods: Six patients (4 men and 2 women) who underwent ASDO surgery for beak-type OPLL in the thoracic spine with a follow-up period of at least 2 years were included in the cohort.
A Second Near-Infrared Window-Responsive Metal-Organic-Framework-Based Photosensitizer for Tumor Immunotherapy via Synergistic Ferroptosis and STING Activation.

Photodynamic therapy (PDT) holds promise as a cancer treatment modality due to its potential for enhanced therapy precision and safety. To enhance deep tissue penetration and minimize tissue adsorption and phototoxicity, developing photosensitizers activated by second near-infrared window (NIR-II) light shows significant potential. However, the efficacy of PDT is often impeded by tumor microenvironment hypoxia, primarily caused by irregular tumor vasculature.
