Abstract	Extractive foraging is considered a key selective pressure for the evolution of primate cognitive abilities-the extractive foraging hypothesis. Although tool-use and substrate-use are representatives of the foraging strategy, some primates engage in extractive foraging without external objects. Manual processing skills of prickly foods have been described in some species, whereas there are few studies on other type of food defenses. Here, I describe extractive foraging of hard-shelled walnuts by wild Japanese macaques (Macaca fuscata), focusing on whether they accomplish the tasks only by their physical strength or require manual and/or oral processing skills to crack open the walnut shells. The study subjects comprised all members of troop B

Abstract	An 84-year-old man underwent right basal segmentectomy for primary lung cancer and developed empyema accompanied by a bronchopleural fistula (BPF). Emergency open-window thoracotomy was performed. Although the general and nutritional conditions improved, the fistula did not close naturally, and we planned to close it 6 months after surgery. In this report, we describe, for the first time, a novel method for closing BPF using an endobronchial Watanabe spigot (EWS), polyglycolic acid (PGA) sheet and N-butyl-2-cyanoacrylate (NBCA). We named this method the"sandwich method."

Abstract	A 64-year-old female with chronic renal failure had been receiving continuous ambulatory peritoneal dialysis (CAPD). She developed acute hydrothorax in the right pleural cavity 1 year after the commencement of CAPD. Scintigraphy revealed a diagnosis of pleuroperitoneal communication, and we performed video-assisted thoracoscopic surgery. We infused a dialysis solution containing indocyanine green (ICG) through CAPD catheter. Near-infrared fluorescence thoracoscopy revealed a fistula that could not be identified by white light. We sutured the fistula covered with a polyglycolic acid sheet and fibrin glue. The CAPD was able to be resumed 8 days after surgery, and there was no recurrence of pleural effusion 10 months since surgery. Identification of the diaphragmatic fistula is important in the treatment of pleuroperitoneal communication. This technique using near-infrared fluorescence thoracoscopy with ICG was useful in identifying the fistula, and it emitted sufficient fluorescence even at low concentration ICG.

Abstract	Background: The aim of this study was to assess the ability of radiologic factors such as mean computed tomography (mCT) value, consolidation/tumor ratio (C/T ratio), solid tumor size, and the maximum standardized uptake (SUVmax) value by F-18 fluorodeoxyglucose positron emission tomography to predict the presence of spread through air spaces (STAS) of lung adenocarcinoma. Methods: A retrospective study was conducted on 118 patients those diagnosed with clinically without lymph node metastasis and having a pathological diagnosis of adenocarcinoma after undergoing surgery. Receiver operating characteristics (ROC) analysis was used to assess the ability to use mCT value, C/T ratio, tumor size, and SUVmax value to predict STAS. Univariate and multiple logistic regression analyses were performed to determine the independent variables for the prediction of STAS. Results: Forty-one lesions (34.7%) were positive for STAS and 77 lesions were negative for STAS. The STAS positive group was strongly associated with a high mCT value, high C/T ratio, large solid tumor size, large tumor size and high SUVmax value. The mCT values were - 324.9 ± 19.3 HU for STAS negative group and - 173.0 ± 26.3 HU for STAS positive group (p < 0.0001). The ROC area under the curve of the mCT value was the highest (0.738), followed by SUVmax value (0.720), C/T ratio (0.665), solid tumor size (0.649). Multiple logistic regression analyses using the preoperatively determined variables revealed that mCT value (p = 0.015) was independent predictive factors of predicting STAS. The maximum sensitivity and specificity were obtained at a cutoff value of - 251.8 HU. Conclusions: The evaluation of mCT value has a possibility to predict STAS and may potentially contribute to the selection of suitable treatment strategies.

Abstract	Purpose: This study evaluated the Controlling Nutritional Status (CONUT) score as a prognostic predictor in elderly non-small cell lung cancer (NSCLC) patients with surgical resection. Methods: Overall, 114 patients over 80 years old undergoing curative resection for NSCLC were retrospectively analyzed. Receiver operating characteristic (ROC) analysis was conducted to evaluate the capacity of immune-inflammatory markers to predict overall survival (OS). Cox-proportional hazards regression analysis was implemented to investigate prognostic markers for OS. Results: Based on ROC curves, the CONUT score was found to be the most valuable prognostic marker (area under the curve = 0.716). The high CONUT (≥2) group included 54 patients, and the low CONUT (0 or 1) group included 60 patients. The high CONUT group had poorer prognosis rates compared to the low CONUT group with regard to OS (5-year OS: 46.3% vs. 86.0%, p = 0.0006). In the multivariate data analysis, histology, lymphatic invasion, and CONUT score (hazard ratio: 4.23, p = 0.0003) were found to be exclusive and independent prognostic markers for OS. Conclusion: Preoperatively, the CONUT score can be used as a novel prognostic marker in elderly NSCLC patients. CONUT evaluations can also be used to design nutritional interventions to improve patient outcomes.

Abstract	Objectives: Bimanual coordinated behaviors are critical for detecting robust individual hand preference in nonhuman primates but are particularly challenging to observe in the wild. This study focuses on spontaneous feeding behavior on African ginger (Aframomum sp. and Renealmia sp.), which involves a unimanual task (reaching and pulling out a ginger stem) and a bimanual coordinated task (extracting pith from a ginger stem) by wild western lowland gorillas. Materials and methods: Study subjects were 21 gorillas in the Moukalaba-Doudou National Park, Gabon. We examined whether they exhibit significant hand preference at the individual and group levels for both tasks. Results: Sixteen gorillas showed significant hand preference in the unimanual task, whereas all 21 individuals showed significant hand preference in the bimanual coordinated task. Hand preference was significantly stronger in the bimanual coordinated task than in the unimanual task. It is noteworthy that gorillas showed a significant right-hand preference at the group level for the bimanual task (roughly 70% of the subjects). Discussion: This study confirmed that bimanual coordinated tasks are more sensitive in detecting hand preferences in nonhuman primates. In addition to the bimanual nature of the task, the precision grip for processing and the importance of African ginger as a food resource might influence the expression of hand preference. Evidence of a group-level right-hand preference may support the "postural origins theory." Because all wild African great apes feed on the pith of African ginger, comparing this task and its hand preferences can contribute toward a better understanding of the evolution of handedness in Hominidae.

Abstract	We report the observation of the quantum walks of a phonon, a vibrational quantum, in a trapped-ion crystal. By employing the capability to prepare and observe the localized wave packet of a phonon, the propagation of a single radial local phonon in a four-ion linear crystal is observed with single-site resolution. The results show an agreement with numerical calculations, indicating the predictability and reproducibility of the phonon system. These characteristics may contribute advantageously in the advanced studies of quantum walks, as well as boson sampling and quantum simulation.

Abstract	Background/aim: We report the case of a patient with gastric and bone metastases arising from an invasive lobular carcinoma of the breast coexisting with ductal carcinoma at the same time. Case report: A 68-year-old woman with gastric and right costal tumors was referred to our hospital. Esophagogastroduodenoscopy (EGD) revealed irregular, slightly elevated lesions extending from the gastric body to the antrum, and biopsy specimens revealed a poorly differentiated adenocarcinoma. Furthermore, abdominal contrast-enhanced computed tomography (CT) revealed extensive wall thickening with homogeneous enhancement in the stomach. 18F-2-deoxy-2-fluoro-glucose positron emission tomography (FDG-PET) showed intense FDG uptake in the right mammary gland and right third rib. Moreover, fine-needle aspiration of the third right rib lump and the right breast mass lesion was performed, and subsequent pathological investigations revealed metastatic adenocarcinoma and invasive ductal carcinoma, respectively. Immunohistochemical examination revealed that estrogen receptor was strongly positive (>95%) in breast cancer and focally positive (<5%) in gastric cancer with bone metastasis. In addition, another right breast tumor was detected by breast magnetic resonance imaging (MRI), and biopsy revealed invasive lobular carcinoma that matched the histological findings of bone and gastric lesions, including immunohistochemical examination. The patient was treated with an aromatase inhibitor, a CDK4/6 inhibitor, and a receptor activator of nuclear factor-kappa B ligand (RANKL) monoclonal antibody. She showed no symptoms or disease progression at 9-month follow-up after the initiation of systemic drug treatment. Conclusion: Invasive lobular carcinoma can metastasize to the gastrointestinal tract, and new treatment developments are expected as more cases will accumulate in the future.
