    Abstract Video-assisted thoracoscopic surgery (VATS) anatomical lung resection (ALR) has been gaining popularity in the treatment of lung cancer in line with remarkable advances in both equipment and technique. The development and refinement of its technique have allowed thoracic surgeons to perform a wide variety of challenging and complex procedures in a minimally invasive fashion. Careful and meticulous preparation may shift in the future with the increasing sophistication and capabilities of VATS ALR. Moreover, constant awareness and a structured plan of the procedure are imperative to reducing or preventing complications. Intraoperative major complications during VATS ALR are infrequent, but can have catastrophic consequences. The decision to continue with VATS should take into consideration the surgeon's skill level and ease with the approach and the relative potential benefit against the risk to the patient. We conducted this study to investigate the possible problems during VATS ALR and identify how to solve them based on the previous literature and our institutional data sampling.

    Abstract The environmental degradation of microplastics results in ultrafine particles that may incur severe biological concerns. Despite this, the atmospheric existence of plastics of less than a few microns has barely been investigated due to the particle size limit of conventional analytical methods. This study develops a procedure to quantify and characterize plastic particles (including nanoplastics; less than 1 μm) in the air through fractional sampling, a simple pretreatment method, and pyrolysis-gas chromatography-mass spectrometry (pyr-GC/MS). We targeted 11 major polymers, namely, polyethylene, polypropylene, polystyrene, acrylonitrile-butadiene-styrene resin, styrene-butadiene rubber, polymethylmethacrylate, polycarbonate, polyvinyl chloride, polyethylene terephthalate (PET), polyamide 6, and polyamide 66 (PA66). The average spike and recovery rate of each polymer in the aerosol collected on the roof of a four-story building near a major road in Kyoto, Japan, amounted to 78-130%, with a coefficient of variation of less than 15%. By coupling pyr-GC/MS analysis with fractional sampling of particles within the size range of >11 μm, 11-7.0 μm, 7.0-4.7 μm, 4.7-3.3 μm, 3.3-2.1 μm, 2.1-1.1 μm, 1.1-0.65 μm, 0.65-0.43 μm, it was possible to quantify airborne nano- and microplastics by particle size. Polyethylene, polystyrene, PET, and PA66 were detected in the air, and the total mass concentration of tiny plastic particles (0.43-11 μm) amounted to 1.20 μg/m

    Abstract Forest trees species are often genetically adapted to local environmental conditions. Therefore, local seeds are recommended for ecological restoration. However, seedlings of broad‐leaved tree species, such as Japanese beech (Fagus crenata), are limited in their commercial seedling production in Japan. Thus, long‐distance transfer of seeds and/or seedlings is common. F. crenata's distinct geographical structure is well known; large‐scale seed transfer may increase the risk of genetic disturbance. Several provenance trials of the species revealed that phenotypic traits such as leaf area and bud flush date differed latitudinally and/or between the Pacific Ocean side and the Japan Sea side. We investigated leaf size and bud flush date and identified the chloroplast DNA haplotype of trees planted in two provenance trials established in Hokkaido, Japan. We then examined whether cpDNA haplotype information is useful as a proxy in ecological restoration when using seedlings with incomplete seed source information. This study indicated that suitable seedlings could be selected based on chloroplast DNA haplotype information in F. crenata in the case of incomplete seed source information.

    Abstract We present the case of a patient who developed pulmonary artery occlusion following immune-checkpoint inhibitor (ICI) therapy for non-small cell lung cancer. A 69-year-old man with squamous cell carcinoma (yc-T1cN0M0), initially diagnosed at c-stage IVA (T3N1M1b), in the upper lobe of the left lung, was scheduled to undergo salvage lung resection after ICI therapy. However, he exhibited an occlusion of the lingular pulmonary artery near the clinically metastatic hilar lymph node. To avoid severe adhesions, the patient underwent successful wedge resection without dividing pulmonary vessels and was discharged without complications. Surgeons should be prepared for pulmonary artery changes following ICI therapy.

    Abstract This study aimed to understand the response of neutrophils stimulated by Streptococcus uberis, a major cause of mastitis. It was found that the production of neutrophil extracellular traps (NETs) was induced in milk clots from mastitic milk produced by S. uberis-infected bovine udders. The release of NETs from neutrophils stimulated by S. uberis was investigated. Bovine neutrophils cocultured with S. uberis in vitro released the components of NETs, which contained extracellular DNA and elastase. Bovine mammary epithelial cells (BMECs) incubated in coculture supernatants containing components of NETs, caused cytotoxicity and transcriptional upregulation of inflammatory cytokines, including of interleukin (IL) -1β, tumor necrosis factor (TNF)-α, IL-6, and IL-8, in BMECs. These findings suggest that bovine neutrophils stimulated by S. uberis induce responses that cause exacerbated inflammation, such as NET formation, cytotoxicity against BMECs, and increased production of inflammatory cytokines. Bovine neutrophil responses stimulated by S. uberis could be involved in the progression of S. uberis-induced mastitis.

    Abstract Objectives: We analysed our clinical experience using silk sutures [the double-loop technique (DLT)] or DeBakey type vascular clamp (DeBakey clamp) for pulmonary artery (PA) troubles during anatomical lung resection to validate its practicality and safety.
    Methods: We retrospectively reviewed the records of patients who underwent either of the above clamping techniques during anatomical lung resection at our hospital between April 2007 and August 2022. We measured the PA diameter at the occlusion site on computed tomography images acquired within 1 year pre- and postoperatively. The difference between pre- and postoperative diameters of the occlusion sites was calculated as the change in the PA diameter. We zoned the occlusion site of the PA to adjust for variation. PA deformation was evaluated as an adverse event caused by clamping.
    Results: Ultimately, 27 and 26 patients who underwent the DLT and DeBakey clamp, respectively, were included. No additional injury due to the clamp procedure was found in either group. For zone R1/L1, defined as the main PA, the median changes in the PA diameter were 0.02 (-0.7 to 0.27) mm for the DLT and 0.36 (-0.28 to 0.89) mm for the DeBakey clamp. No significant differences were observed between the 2 groups (P = 0.106). Furthermore, no aneurysms, dissections, or stenoses were found in either group.
    Conclusions: The DLT and DeBakey clamp had only minimal effects on the occlusion site of the PA. The DLT is a practical thoracoscopic technique for PA bleeding when primary haemostasis has been achieved.

    Abstract Familial hypercholesterolemia (FH) is one of the most common autosomal codominant Mendelian diseases. The major complications of FH include tendon and cutaneous xanthomas and coronary artery disease (CAD) associated with a substantial elevation of serum low-density lipoprotein levels (LDL). Genetic counseling and genetic testing for FH is useful for its diagnosis, risk stratification, and motivation for further LDL-lowering treatments. In this study, we summarize the epidemiology of FH based on numerous genetic studies, including its pathogenic variants, genotype-phenotype correlation, prognostic factors, screening, and usefulness of genetic counseling and genetic testing. Due to the variety of treatments available for this common Mendelian disease, genetic counseling and genetic testing for FH should be implemented in daily clinical practice.

    Abstract Subsegmentectomy is an optional treatment for early primary lung cancer presenting without adequate surgical margins for wedge resection. There are no previous reports regarding a robotic single subsegmentectomy. We report a robotic single subsegmentectomy of the right anterior medial subsegment (S3b). The lung parenchyma was dissected with a Vessel Sealer Extend along the intersubsegmental veins for proper lung mobilization to solve the directional limitations of the robotic stapler. Additionally, we inserted the most ventral port from the subcostal region to increase the distance between the ports. Performing a robotic single subsegmentectomy is challenging. However, our techniques help to achieve a safe and effective operation.

    Abstract Companion diagnostics (CoDx) will likely continue to rapidly increase in number and application to disease areas including solid tumors, for example EGFR for gefitinib and ALK fusion gene for crizotinib in non-small-cell lung cancer; KRAS against the use of cetuximab and panitumumab in colorectal cancer; HER2 for trastuzumab in breast cancer. CoDx are an indispensable part of personalized medicine and pharmacogenomics. In CoDx development, there are still many challenges, such as the business model promoting cooperation between diagnostics and pharmaceutical companies, and also the regulations related to CoDx. The FDA notice on the development of CoDx in 2011 recommended the co-development of a new drug and CoDx as the best practice, and the Ministry of Health, Labour and Welfare in Japan also issued a statement in 2013. In addition, the recent discovery of many novel variants in the DNA sequence, advances in sequencing and genomic technology, and improved analytic methods have enabled the impact of germline and somatic mutations to be determined using multiplex diagnosis. The complex challenges to develop CoDx necessitate a close collaboration among academic institutions, regulatory authorities, and pharmaceutical companies. [Review].

    Abstract This case report discusses the case of a 76-year-old woman with choroidal metastasis from breast cancer who was treated with intensity-modulated radiation therapy (IMRT). Choroidal metastasis is a common ocular tumor, and the occurrence of this condition has increased due to improved diagnostic tools and longer survival of metastatic patients. IMRT is an innovative radiation therapy technique that reduces complications and improves the curative effect by concentrating radiation on the tumor while minimizing exposure to surrounding tissues. In this case, the patient had a history of breast cancer and was undergoing chemotherapy when she presented with vision loss and blurred vision. Imaging tests confirmed choroidal metastasis, and IMRT was performed under the guidance of a radiation oncologist. After treatment, the choroidal lesion dramatically reduced in size, and the patient's vision improved. The text concludes that radiation therapy, including IMRT, is becoming more common as a treatment for ocular metastasis to improve vision and preserve the eye. When choosing radiation therapy, it is essential to consider the size of the tumor and the impact on surrounding tissues. IMRT is an effective treatment that enables precise and concentrated irradiation of the tumor tissue while minimizing exposure to normal tissues.
