Background: Appetite loss in older adults raises the risk of malnutrition and frailty. The recent emphasis on psychological and social support for appetite loss reveals the importance of robust social networks. Depression is linked to a decline in appetite and social networks. Social networks may influence appetite directly and indirectly through depression. This exploratory cross-sectional study categorizes social networks into family and friend networks to elucidate their direct and indirect effects. Methods: The study analyzed 193 community-dwelling older adults (women 78.2%; mean age 77.1±5.3 years) who participated in health-checkup events in two cities in Japan. Appetite was assessed using the Japanese version of the Simplified Nutritional Appetite Questionnaire, and family and friend networks were assessed using the Lubben Social Network Scale-6. Depression was assessed using the Geriatric Depression Scale-15. Based on previous research, we constructed a causal model examining the impacts of family and friend social networks and depression on appetite and calculated the direct and indirect effects through structural equation modeling. Results: The family network had a direct effect on appetite (path coefficient=0.18) and an indirect effect via depression (path coefficient=0.0608). Conversely, the friend network was not directly associated with appetite but had an indirect effect through depression (path coefficient=0.095). The model exhibited a good fit. The mechanism of influence on appetite varied between the networks. Conclusion To prevent appetite loss, social networks with family and friends should be assessed separately, and tailored support should be provided for each.

Objective: The “One-half Rule” for OTC drug sales has been eliminated, and furthermore, “Remote-controlled sales” of OTC medicines by qualified sellers is under discussion. The number of registered sales clerks is greater than the number of pharmacists selling OTC drugs. Although this is a result of the different employment status of pharmacists and registered sales clerks due to their salary structure and role in the store, it can be said that registered sales clerks are the main people to deal with the general public when they purchase OTC drugs. Therefore, we conducted a survey of registered sales clerks in order to understand their actual work and their awareness of the revision of the system, and to estimate the impact on customers and patients.Methods: The questionnaire was administered at an external training session held by the Tokyo Metropolitan Druggist Association from April 16 to 18, 2022.Results: Valid responses were obtained from 319 participants. Responses were obtained for the ratio of work as a registered sales clerk before becoming a qualified, after qualification (present), and what they think would be an ideal work ratio. The percentage of “pharmaceutical consultation and sales” increased from 7.7 to 15.9, and finally 26.4% before, at present, and ideally, respectively. It was clear that the acquisition of the certification increased the percentage of specialized tasks and that the respondents would like to further increase this percentage. Awareness of the “One-half Rule” and “Remote-controlled sales” was 43.6 and 23.8%, respectively.Conclusion: It was inferred that the introduction of “Remote-controlled sales” would improve convenience but dilute interpersonal work, which would hinder the operation, maintenance, and management of the store, including courteous customer service that cannot be handled through a screen. Therefore, from this study, we believe that registered sales clerks express doubt about the introduction of “Remote-controlled sales”.

Objective: Therapeutic antibodies have few varieties of side effects due to their high specificity; however, many therapeutic antibodies have serious side effects. A thorough understanding of the side effects is crucial for early recognition and optimal management. To facilitate the understanding of the side effects of therapeutic antibodies, this study attempted to classify therapeutic antibodies based on their side effects using principal component analysis (PCA) and cluster analysis. Method: We collected data on the serious side effects of therapeutic antibodies from package inserts and created a therapeutic antibody-side effect matrix, with therapeutic antibodies as indices and side effects as columns. PCA was performed on the therapeutic antibody-side effect matrix, and hierarchical cluster analysis was performed using principal components. Results: The therapeutic antibodies were classified into four clusters. Cluster 1 included immune checkpoint inhibitors, and featured type 1 diabetes, thyroid disorder, and myasthenia gravis. Cluster 2 included antibodies that inhibit the vascular endothelial growth factor pathway, and featured impaired wound healing, nephrotic syndrome, and thrombosis. Cluster 3 included anti-epidermal growth factor receptor antibodies, and featured diarrhea, hypomagnesemia, and skin disorders. Cluster 4 included other therapeutic antibodies, and featured infection, bone marrow suppression, and hypersensitivity. Conclusion: Therapeutic antibodies can be classified based on their side effects. The results of this study make it easier to understand the side effects of therapeutic antibodies with complex profiles. A better understanding facilitates early detection of side effects and enables high-quality management of side effects.

Methods: HFCs were obtained from patients with LSS who had undergone decompression surgery. The cells were stimulated with TGF-β and pretreated with either the p38 mitogen-activated protein (MAP) kinase inhibitor SB203580 or the p44/42 MAP kinase inhibitor FR180204. IL-6 secretion in the cell culture medium and IL-6 messenger RNA (mRNA) expression levels were analyzed using an enzyme-linked immunoassay and real-time polymerase chain reaction, respectively. Results: TGF-β administration resulted in a dose- and time-dependent stimulation of IL-6 release. Treatment with SB203580 and FR180204 markedly suppressed TGF-β–induced IL-6 secretion from HFCs. Moreover, these inhibitors suppressed IL-6 mRNA expression in response to TGF-β stimulation. Conclusions Our findings indicate that TGF-β induces IL-6 protein secretion and gene expression in HFCs through the activation of p38 or p44/42 MAP kinases. These results suggest a potential association between IL-6–mediated inflammatory response and tissue hypertrophy in LSS, and we provide insights into molecular targets for therapeutic interventions targeting LSS-related inflammation through our analysis of the MAP kinase pathway using HFCs.

Methods: Five formalin-embalmed human cadavers were used. We assessed the proportion of segmental arteries and veins that intersected the IVD in the L2–L5 range and their course on the anterior part of the spinal column. Results: The segmental arteries and veins commonly intersect the anterior part of the IVD (artery, 28.1%; vein, 42.1%). Seven of 10 (70%) segmental arteries at L2 intersected the IVD, but only one artery intersected the IVD at L3 and L4. The proportions of segmental veins that intersected the IVD were 60%, 50%, and 16.7% at L2, L3, and L4, respectively. Conclusions The segmental arteries and veins frequently intersect the IVD in the anterior part of the spinal column. Therefore, it is necessary to consider these individual anatomical features to prevent vascular damage during lateral lumbar interbody fusion surgery.

We report a case of a 56-year-old woman. She had a history of emergent ascending aorta replacement due to type A dissection. Seven years later, aortic arch enlargement (55 mm) was detected on CT scan, and indicated secondary repair. Because of the existence of the aberrant right subclavian artery (ARSA), the safer surgical management needed to be discussed. Total arch replacement with the use of open stent-grafting technique and extra-anatomical reconstruction of ARSA was chosen for the treatment. In the operation, straight woven grafts (7 mm in diameter) were firstly anastomosed to the bilateral axillary arteries. Deep hypothermic circulatory arrest with antegrade cerebral perfusion through median sternotomy was established. The aortic arch was transected between the right and left subclavian arteries. The left subclavian artery was ligated at its origin, and an aortic open stent graft was inserted distally. An aortic reconstruction was performed between the left common carotid artery and the left subclavian artery with a 4 branched J-graft. The left carotid artery was reconstructed anatomically, and the tube grafts anastomosed to the bilateral axillary arteries were reconstructed in an extra-anatomical fashion. On the 11th postoperative days, coil-embolization of the ARSA was performed to complete the treatment. The patient had an uneventful post-operative recovery. Total arch replacement using an open stent-grafting technique was a feasible treatment option for the aortic arch aneurysm with ARSA.

A 79-year-old woman presented to our hospital with high energy trauma. Enhanced CT revealed injury to the aortic arch. The left carotid artery was pulled out due to extension force and a drawing out lesion formed. Cardiopulmonary bypass was established with cannulation of the right femoral artery and the right atrium, and systemic cooling was started. We opened the aortic arch with deep hypothermic circulatory arrest, and detected a 10 mm drawing out lesion at the bottom of the left carotid artery. Aortic arch was transected at the distal of the left carotid artery to exclude the drawing out lesion, and partial arch replacement was performed. The patient's postoperative course was uneventful, and she was discharged from our hospital without any complication.

A 51-year-old man was referred to our hospital with pain and coldness of the upper left extremity. Contrasted computed tomography revealed a silhouette protruding into the aortic arch. Peripheral embolism in upper left extremity by tumor or thrombosis was suspected. Magnetic resonance imaging revealed a mobile mass in the aortic arch. To prevent recurrent embolization, the mass and the aortic arch to which the mass was attached were excised and partial arch replacement was performed under cardiopulmonary bypass. Histologically, the mass was a fibrin thrombus with no malignancy. The aortic wall showed only mild atherosclerosis of the intima. No thrombotic predisposition such as protein S or C deficiency or antiphospholipid antibody syndrome was observed. Anticoagulant therapy was started and the patient was discharged on postoperative day 10 without recurrent thromboembolism. Three years have passed since the operation and there is no recurrence of thromboembolism.
