RESUMO
BACKGROUND: In Japan, over 450 public health centers played a central role in the operation of the local public health system in response to the COVID-19 pandemic. This study aimed to identify key issues for improving the system for public health centers for future pandemics. METHODS: We conducted a cross-sectional study using an online questionnaire. The respondents were first line workers in public health centers or local governments during the pandemic. We solicited open-ended responses concerning improvements needed for future pandemics. Issues were identified from these descriptions using morphological analysis and a topic model with KHcoder3.0. The number of topics was estimated using Perplexity as a measure, and Latent Dirichlet Allocation for meaning identification. RESULTS: We received open-ended responses from 784 (48.6%) of the 1,612 survey respondents, which included 111 physicians, 330 nurses, and 172 administrative staff. Morphological analysis processed these descriptions into 36,632 words. The topic model summarized them into eight issues: 1) establishment of a crisis management system, 2) division of functions among public health centers, prefectures, and medical institutions, 3) clear role distribution in public health center staff, 4) training of specialists, 5) information sharing system (information about infectious diseases and government policies), 6) response to excessive workload (support from other local governments, cooperation within public health centers, and outsourcing), 7) streamlining operations, and 8) balance with regular duties. CONCLUSIONS: This study identified key issues that need to be addressed to prepare Japan's public health centers for future pandemics. These findings are vital for discussions aimed at strengthening the public health system based on experiences from the COVID-19 pandemic.

A 62-year-old male presenting with gross hematuria and right renal mass was referred to our Urology Department. Computed tomography revealed a right renal mass, with multiple pulmonary lesions. He underwent right nephrectomy for highly suspected renal cell carcinoma with pulmonary metastases (cT3aN0M1). The pathological diagnosis was clear cell renal cell carcinoma, pT1b. Following surgery, he was treated with multiple regimens of chemotherapy, ranging from interferon alpha, multiple tyrosine kinase inhibitors such as sorafenib, axitinib, pazopanib and cabozantinib, everolimus, and nivolumab, all of which were discontinued after its induction, either due to adverse events or progressive disease. He was finally administered Sunitinib as the 8th line "last-ditch" treatment, which resulted in significant tumor shrinkage. No disease progression has been observed 25 months after initiating sunitinib administration.

Osteoclasts are multinucleated cells responsible for bone resorption. Src homology 3 (SH3) domain-containing protein-2 (SH3P2)/osteoclast-stimulating factor-1 regulates osteoclast differentiation, but its exact role remains elusive. Here, we show that SH3P2 suppresses osteoclast differentiation. SH3P2 knockout (KO) mice displayed decreased femoral trabecular bone mass and enhanced localization of osteoclasts on the tibial trabecular bone surface, suggesting that SH3P2 suppresses bone resorption by osteoclasts. Osteoclast differentiation based on cellular multinuclearity induced by macrophage colony-stimulating factor and receptor activator of nuclear factor-κB ligand (RANKL) was enhanced in bone marrow-derived macrophages lacking SH3P2. RANKL induced SH3P2 dephosphorylation, which increased the association of actin-dependent motor protein myosin 1E (Myo1E) with SH3P2 and thereby prevented Myo1E localization to the plasma membrane. Consistent with this, Myo1E in the membrane fraction increased in SH3P2-KO cells. Together with the attenuated osteoclast differentiation in Myo1E knocked down cells, SH3P2 may suppress osteoclast differentiation by preventing their cell-to-cell fusion depending on Myo1E membrane localization.

Hydrogen sulfide (H2S) is an endogenous gaseous transmitter known to play an important role in biological functions. For the hepatic and intrahepatic targeting of H2S prodrug at the cellular level, we developed two types of sulfo-albumins, in which five sulfide groups (source of H2S) were covalently bound to succinylated (Suc) or galactosylated (Gal) bovine serum albumin (BSA). Sulfo-BSA-Suc and polyethylene glycol (PEG)-Sulfo-BSA-Gal, both released H2S in the 5 mM glutathione solution, but not in the plasma. Sulfo-BSA-Suc and PEG-Sulfo-BSA-Gal were taken up by RAW264.7 cells (mouse macrophage-like cells) and Hep G2 cells (human hepatocellular carcinoma cells), respectively, and H2S was released. These results indicate that Sulfo-BSA-Suc and PEG -Sulfo-BSA-Gal selectively released H2S intracellularly. In a biodistribution study, up to 80% of 111In-labeled Sulfo-BSA-Suc and PEG-Sulfo-BSA-Gal rapidly accumulated in the liver, 30 min after intravenous injection in mice. Furthermore, 111In-labeled Sulfo-BSA-Suc and PEG-Sulfo-BSA-Gal predominantly accumulated in liver nonparenchymal (endothelial cells and Kupffer cells) and parenchymal cells (hepatocytes), respectively. These findings suggest that targeted delivery of H2S prodrug to a specific type of liver cells was successfully achieved by bioconjugation.

BACKGROUND: In the eighth edition of the TNM classification of lung cancer, the M1b and M1c descriptors are newly defined by the number of extrathoracic metastases. To verify the prognostic value of these descriptors in Japan, we reclassified our cases and re-evaluated prognosis in M1b and M1c patients. METHODS: All non-small cell lung cancer (NSCLC) patients with extrathoracic metastases who visited Saitama Medical Center from 2010 to 2016 were evaluated, divided according to the eighth edition of the TNM classification criteria into two groups (M1b, patients with single extrathoracic metastasis, and M1c, patients with multiple extrathoracic metastases), and followed up until December 31, 2017. Survival time analysis was performed using the Kaplan-Meier method, and between-group differences in overall survival time (OS) were evaluated by the log-rank test. RESULTS: A total of 231 NSCLC patients were divided into 57 patients with M1b and 174 with M1c. Median OS was 15.2 months (95% confidence interval [CI]: 9.3-19.9) and 7.3 months (95% CI 5.7-10.7) for M1b and M1c, respectively, with no significant between-group difference (P = 0.239). However, after excluding patients with epidermal growth factor receptor (EGFR) mutation or echinoderm microtubule-associated protein-like 4 and anaplastic lymphoma kinase (EML4-ALK) fusion gene, median OS was 12.9 months (95% CI 7.2-19.9) for M1b and 5.4 months (95% CI 3.8-6.3) for M1c, respectively, showing a significant difference (P = 0.029). CONCLUSIONS: The effect of therapy directed toward EGFR mutation or EML4-ALK fusion gene might obscure the significant prognostic difference between M1b and M1c.

Recovery of the organics in industrial wastewaters/liquid wastes as polyhydroxyalkanoate (PHA) and/or glycogen (GLG) in waste activated sludge is a useful strategy to not only improve the resource value of waste activated sludge but also reduce the energy and cost of waste disposal and wastewater treatment. This study aimed to evaluate the potential of activated sludge to accumulate PHA and GLG using complex substrates (actual and simulated industrial wastewaters/liquid wastes) in addition to various simple organic substrates (organic acids, saccharides, and glycerol). The 24 h PHA and GLG accumulation experiments resulted in the accumulation of up to 25.5%, 6.0% and 14.1% of polyhydroxybutyrate (PHB), polyhydroxyvalerate (PHV) and GLG, respectively, from simple substrates, and up to 9.8%, 0.1% and 14.6%, respectively, from complex substrates. The results indicated that activated sludge can accumulate PHA and GLG even from complex wastewater substrates, although the accumulated PHA and GLG levels were not sufficiently high. The results also indicated that the PHA and GLG accumulation abilities of activated sludge from complex substrates can be drastically enhanced by a short-term acclimation to the corresponding substrate. This study will present the practical implications for value-added resource production through the combined use of waste activated sludge and industrial wastewaters.

We report a rare case of a de novo ruptured aneurysm arising from the twig-like networks(TLN)of an anomalous collateral artery associated with an aplastic or twig-like middle cerebral artery(Ap/T-MCA). A 65-year-old woman with a decreased level of consciousness, who had been diagnosed with a right Ap/T-MCA and was treated with coil embolization for a ruptured A1 aneurysm at the origin of the anomalous collateral artery 4 years ago, was transferred to our hospital. Head CT revealed an intracerebral hematoma extending from the right frontal lobe to the caudate nucleus with intraventricular hemorrhage. Subsequent 3D-rotational angiograms revealed a ruptured de novo aneurysm arising from the TLN and regrowth of the residual neck of the coiled aneurysm. The two aneurysms were successfully treated by surgical clipping combined with superficial temporal artery middle cerebral artery anastomosis in the subacute phase. To our knowledge, only 11 cases of this type of aneurysm have been reported, including our case, and this is the first report of a de novo aneurysm within the TLN so far. Although all previously reported aneurysms were small(<5-6mm), 10 of them(91%)ruptured. These data may indicate the vulnerability of this type of aneurysm to rupture despite their small size, probably due to hemodynamic stress and the fragile nature of their immature walls. To prevent recurrence of hemorrhage in these cases, revascularization may be necessary in addition to surgical clipping. Whether this concept is correct is an open question. Further studies are necessary to examine this issue.

Down syndrome (DS), also known as Trisomy 21, is the most common chromosome aneuploidy in live-born children and displays a complicated symptom. To date, several kinds of mouse models have been generated to understand the molecular pathology of DS, yet the gene dosage effects and gene(s)-phenotype(s) correlation are not well understood. In this study, we established a novel method to generate a partial trisomy mice using the mouse ES cells that harbor a single copy of human artificial chromosome (HAC), into which a small human DNA segment containing human chromosome 21 genes cloned in a bacterial artificial chromosome (BAC) was recombined. The produced mice were found to maintain the HAC carrying human genes as a mini-chromosome, hence termed as a Trans-Mini-Chromosomal (TMC) mouse, and HAC was transmitted for more than twenty generations independent from endogenous mouse chromosomes. The three human transgenes including cystathionine ß-synthase, U2 auxiliary factor and crystalline alpha A were expressed in several mouse tissues with various expression levels relative to mouse endogenous genes. The novel system is applicable to any of human and/or mouse BAC clones. Thus, the TMC mouse carrying a HAC with a limited number of genes would provide a novel tool for studying gene dosage effects involved in the DS molecular pathogenesis and the gene(s)-phenotype(s) correlation.

OBJECTIVES: This study investigates the association between workaholism and headaches causing presenteeism among Japanese employees. METHODS: Used data from self-reporting questionnaire and annual health checkups. Workaholism was assessed using the Dutch Workaholic Scale and headaches causing presenteeism were identified as the symptom hindering work. We performed a logistic regression analysis adjusted for covariates. RESULTS: Among 5802 respondents, 3.7% cited headaches as the symptom hindering work. We found an association between workaholism and such headaches (odds ratios [OR]: 1.05, 95% confidence intervals [CI]: 1.03-1.08). Both working excessively (OR: 1.08, 95% CI: 1.04-1.12) and working compulsively (OR: 1.10, 95% CI: 1.05-1.15) subscales were also related. CONCLUSIONS: Workaholism may lead to productivity loss due to headaches, and addressing workaholism can prevent this loss. Combining health examination data with work hours data may enable the early detection of workaholism.

This study aims to determine the factors that encourage older workers to continue working. This study had an exploratory sequential design using a mixed-methods approach, including interviews and questionnaire surveys. In the interview survey, we targeted 30 workers aged between 60-65 across three manufacturing companies. After using the results of the content analysis in the interviews, we conducted an online questionnaire survey with 1,500 workers aged between 60-89 across the country. We analyzed whether the 15 factors were related to intention to continue working using logistic regression analysis. We identified factors affecting job continuity from three perspectives: individual, company, and life. We determined several factors: health condition, job performance, self-esteem, conservatism, employment system, workload, medical insurance and welfare programs, monetary and non-monetary rewards, relationships, attachment to the organization, distance between living and work, social support, economic situation, and employment policy. In the questionnaire survey, some factors had no relationship with job continuity, including conservatism, employment systems, monetary rewards, and the distance between living and work. Employers and policymakers can use the findings to consider appropriate ways of supporting older workers.
RESUMO
OBJECTIVES: Occupational future time perspective (OFTP) is important concept for the successful career in older workers. The purpose of this study was to examine the associations between individual and work-related factors and OFTP. METHODS: We conducted a cross-sectional study via an online questionnaire survey. Respondents were stratified sampled according to the distribution of workers across Japan. To assess OFTP, we used the Japanese version of the OFTP scale. We included the factors such as sex, age, education, marital status, subjective health status, personal income, length of employment, industry, size of company, employment status, working days per week, and night shift. Multiple regression analysis was employed to calculate the regression coefficients for each factor, with OFTP serving as the dependent variable. RESULTS: We totally included 1,484 respondents. Our findings indicated that higher OFTP was associated with higher education, better subjective health status, higher personal income, and smaller size of company. Compared to the manufacturing, certain industries such as agriculture and forestry, transportation and postal services, and healthcare showed lower OFTP. In contrast to permanent workers, contract and part-time workers demonstrated lower OFTP, whereas owners of non-family businesses exhibited higher OFTP. Furthermore, individuals working 1-4 days per week showed lower OFTP compared to those working 5 days per week. CONCLUSIONS: Older workers facing limitations in resources, such as educational background, personal income, precarious employment, and health status, tend to have lower OFTP. Such individuals should be given priority for support and assistance.
RESUMO
OBJECTIVE: This study aimed to clarify the differences in the perioperative data of patients with extramedullary and intramedullary tumors and estimate the impact of surgery on medical costs. METHODS: This single-center retrospective study included consecutive patients who underwent spinal tumor resection between September 2020 and December 2022. The perioperative medical information and medical costs for individual patients were obtained from their medical records. RESULTS: Thirty-two patients with extramedullary spinal cord tumors and 18 with intramedullary spinal cord tumors were included in the study. The 2 groups had no difference in surgery-related or major systemic complications. However, the operation time and the length of hospital stay were significantly longer and activities of daily living at discharge tended to worsen in the intramedullary tumor group compared to those in the extramedullary tumor group. As a result, the discharge outcome was significantly different between the 2 groups. The total medical costs for intramedullary tumors were approximately 1.43 times higher than those for extramedullary tumors. Further, a better functional outcome at discharge can save medical costs, regardless of extramedullary or intramedullary tumors. CONCLUSIONS: Surgery for intramedullary tumors can be performed with similar perioperative risks as for extramedullary tumors. However, intramedullary tumors are associated with concerns, such as prolonged hospitalization and worsening of activities of daily living at discharge, which ultimately result in higher medical costs.

Airway complications that occur after anterior cervical spine surgery pose a life-threatening risk, which encompasses complications including prolonged intubation, unplanned reintubation, and/or necessity of tracheostomy. The present study aimed to identify the surgical risks associated with postoperative airway complications in neurosurgical training institutes. A retrospective, multicenter, observational review of data from 365 patients, who underwent anterior cervical spine surgery between 2018 and 2022, at three such institutes was carried out. Postoperative airway complication was defined as either the need for prolonged intubation on the day of surgery or the need for unplanned reintubation. The perioperative medical information was obtained from their medical records. The average age of the cohort was over 60 years, with males comprising approximately 70%. Almost all surgeries predominantly involved anterior cervical discectomy and fusion or anterior cervical corpectomy and fusion, with most surgeries occurring at the level of C5/6. In total, 363 of 365 patients (99.5%) were extubated immediately after surgery, and the remaining two patients were kept under intubation because of the risk of airway complications. Of the 363 patients who underwent extubation immediately after surgery, two (0.55%) required reintubation because of postoperative airway complications. Patients who experienced airway complications were notably older and exhibited a significantly lower body mass index. The results of this study suggested that older and frailer individuals are at an elevated risk for postoperative airway complications, with immediate postoperative extubation generally being safe but requiring careful judgment in specific cases.

Immune checkpoint inhibitors (ICIs) have been widely used as standard therapies for various cancers. However, in 20-30% of cases, ICIs can lead to immune-related adverse events (irAEs), which sometimes require discontinuation of treatment. Due to the increased risk of irAEs, patients with pre-existing autoimmune diseases (AI) are often advised against receiving ICIs. However, there has not been sufficient objective risk assessment for AI. In our study, we conducted logistic regression analysis to assess the risk of irAEs by analyzing 478 cases that received anti-PD-(L)1 Ab and/or anti-CTLA4 Ab at our hospital between April 3, 2017, and May 24, 2022. Among these cases, 28 (5.9%) had pre-existing AI. We selected several independent factors for analysis: gender, age, performance status (PS), cancer type, type of ICI, type of combined anti-cancer agents, best overall response, and pre-existing AI. The adjusted odds ratio (OR) of AI for irAE occurrence was 2.52 [95% CI: 1.08-5.86] (p = 0.033), and the adjusted OR of AI for ICI discontinuation due to irAE was 3.32 [1.41-7.78] (p = 0.006). Patients with pre-existing AI experienced a significantly shorter irAE-free survival time compared to those without AI (median irAE-free survival: 5.7 months [95% CI: 3.5-7.8] vs 10.4 months [95% CI: 7.9-12.9], respectively, p = 0.035). Frequently observed irAEs in full ICI cohort, such as dermatologic issues (7.5%), pneumonitis (7.1%), hepatitis (4.6%), and hypothyroidism (4.2%), were often accompanied by pre-existing AI. Furthermore, pre-existing AI flared up in 6 cases (37.5% in AI-positive irAE-positive cases). The activity of AI was not related to the occurrence of irAEs. Grade 3 or higher irAEs were observed in 6 out of 20 (30.0%) cases in AI-accompanied patients complicated with irAEs. Although having a complicated AI increases the risk of irAEs, it may not necessarily be a contraindication for ICI treatment if closely monitored. (292<300 characters).

Introduction: Immune checkpoint inhibitor (ICI)-based treatment has become standard treatment for patients with advanced NSCLC. We aimed to determine the survival benefit of upfront radiotherapy for brain metastases (BMs) in patients with NSCLC who received ICI alone (ICI-alone) or with chemotherapy (ICI-chemo). Methods: This study included consecutive patients with NSCLC having BMs who received ICI alone or ICI-chemo at 50 institutes between February 2017 and September 2021. The presence of BMs was confirmed by imaging before treatment. Treatment outcomes were compared between patients who did and did not receive upfront radiotherapy for BMs. Potential confounding factors were adjusted between the groups through inverse probability treatment weighting (IPTW) analysis and overlap weighting (OW) analysis with propensity scores. Results: Patients were grouped as ICI-alone cohort, 224 patients (upfront-radiotherapy group, 135 patients; no-radiotherapy group, 89 patients) and ICI-chemo cohort, 367 patients (upfront-radiotherapy group, 212 patients; no-radiotherapy group, 155 patients). In the ICI-alone cohort, the overall survival of the upfront-radiotherapy group was significantly longer than that of the no-radiotherapy group (IPTW-adjusted hazards ratio [HR] = 0.45 [95% confidence interval [CI]: 0.29-0.72], OW-adjusted HR = 0.52 [95% CI: 0.35-0.77]). In contrast, in the ICI-chemo cohort, the OS of the upfront-radiotherapy group was not significantly different from that of the no-radiotherapy group (IPTW-adjusted HR = 1.02 [95% CI: 0.70-1.48], OW-adjusted HR = 0.93 [95% CI: 0.65-1.33]). Conclusions: Upfront radiotherapy for BMs was associated with longer overall survival in patients with NSCLC who received ICI alone; however, it did not exhibit survival benefits in the patients who received ICI-chemo.
RESUMO
A critical issue in the study of scientific communication from a systems theoretical perspective is its role in multiple intersystem relationships. During COVID-19, politics has adopted scientific findings to inform political decisions. However, science has in response actively coordinated its operations for providing desired stimuli to politics. Luhmann identified advice as a form of structural coupling that links political and scientific systems. Advice is not a monolithic intervention by which one side acts on the other but is rather an interface that enables the two systems to relate through distancing. In this article, I empirically illustrate how the structural coupling of the political system and scientific system through advice manifests itself in an examination of the roles that various organizations (expert meeting and cluster task forces) have played in Japan's response to COVID-19. Through this analysis, I provide a theoretical insight regarding these organizations and a more detailed case analysis of the transformation of certain organizations to re-describe the system theoretical insights of advice in the form of scientific communication between politics and science.
RESUMO
OBJECTIVE: This study aimed to structure supervisory support and clarify the relationship between supervisors' work engagement and support for their subordinates. METHODS: We conducted a cross-sectional study in a manufacturing company using a questionnaire survey. Supervisors provided open-ended responses regarding the provision of support for their subordinates. Using text mining, we structured these descriptions into multiple categories, assigned words to them, and analyzed frequently mentioned categories by the level of work engagement. RESULTS: We obtained responses from 729 participants that included 13,968 words. We structured supervisory support by three categories (contents, direction, and attitude toward support) and 11 subcategories. As supervisors' work engagement increased, the rates of mentioning information retrieval, information transmission, and carefulness increased. CONCLUSIONS: Supervisors with work engagement could communicate with each other and be careful in providing support to their subordinates.

OBJECTIVES: Labor and social security attorneys (LSSAs) are involved in various positions in harmonizing work with disease treatment; however, their qualification requirements do not include knowledge about the same. Expectations of their involvement in harmonizing work with disease treatment are insufficient. This study aimed to identify the competencies expected of the labor and social security LSSAs in harmonizing work with disease treatment. METHODS: In step 1, semi-structured interviews were conducted with LSSAs in this field. In step 2, a draft competency list was created based on the interview results. In step 3, the Delphi method was used to conduct a questionnaire survey among LSSAs who had over 10 consultation cases on harmonizing work with disease treatment, and they were asked about the level of importance (how important they thought it was to promote harmonizing work with disease treatment) and level of achievement (how much they had achieved). We also asked them about the competencies they considered necessary and added them as additional items in the draft. In step 4, the results of the previous step were presented to the participants who had given valid answers in step 3, and they were asked whether they would adopt the items as competencies. Items with an agreement rate of 80% or higher were considered competency items. Additionally, we asked them about the level of importance and level of achievement of the additional items created in step 3. RESULTS: In step 1, 24 LSSAs participated, and in step 2, a draft competency list of six major items, 18 medium items, and 71 minor items was created. In step 3, 49 LSSAs participated and 41 cooperated (response rate: 83.6%). Five items were selected for the draft competency list to be newly added. In step 4, 30 LSSAs cooperated (response rate: 73.1%). None of the items had an agreement rate of less than 80%, and over 40% of the items had an agreement rate of 100%. As a result, six major items, 18 medium items, and 76 minor items were selected for the competency list. CONCLUSIONS: This study identified the competencies expected of labor and social security LSSAs in harmonizing work with disease treatment. The results of this study can be used as a reference for developing a systematic training curriculum for LSSAs in this field in the future.

OBJECTIVES: The purpose of this study was to examine, by sex, whether precarious workers in Japan receive less support in the workplace than permanent workers. METHODS: We conducted a cross-sectional study using an online questionnaire in 2022. We stratified participants by sex and performed modified Poisson regression analysis. The outcomes were support from supervisors, co-workers, occupational health professionals, and no one. Adjusted prevalence ratios (aPR) were calculated for contract workers, part-time workers, and dispatched workers, using permanent workers as reference. RESULTS: This study had 21 047 participants. For men, 87.9% were permanent workers; for women, 50.7% were permanent workers and 37.3% were part-time workers. For workplace support, 47.5% of men and 45.2% of women selected superiors; 41.8% of men and 50.5% of women selected colleagues; 16.8% of men and 6.2% of women selected occupational health professionals. Female contract workers were less likely to receive support from their supervisors (aPR 0.88) or co-workers (aPR 0.89). Male part-time workers were less likely to be supported by their co-workers (aPR 0.86). Dispatched workers were less likely to be supported by their supervisors (men aPR 0.71, women aPR 0.84) and co-workers (men aPR 0.73, women aPR 0.77). Part-time and dispatched workers were less likely to receive support from occupational health professionals. CONCLUSIONS: Precarious workers could get less workplace support than permanent workers. This may contribute to occupational health problems with precarious workers.

A 72-year-old female presented with bilateral pulmonary nodules before undergoing surgery for hysteroptosis. Transbronchial biopsy did not lead to a definitive diagnosis. The right mass in the upper lobe was resected through video-assisted thoracic surgery. Pathological findings showed granulomatosis with polyangiitis. However, the patient was negative for serum proteinase 3-anti-neutrophil cytoplasmic antibody. Although the nodule in the left lower lobe progressed, the serum inflammatory reaction yielded negative results. Resection of the nodule in the left lower lobe revealed identical pathological findings with those of the right pulmonary mass. Following total hysterectomy for hysteroptosis, the pathological findings indicated granulomatosis with polyangiitis.
