The association between stair climbing and modifiable cardiovascular disease risk factors: the Suita Study.

BACKGROUND: Stair climbing is a readily available form of physical activity with potential cardiovascular benefits. This study aimed to investigate the association between stair climbing and numerous modifiable cardiovascular disease (CVD) risk factors. METHODS: In this cross-sectional study, we used data from 7282 Japanese people (30-84 years) residing in Suita City, Osaka. CVD risk factors and stair climbing frequency were assessed during the Suita Study health examination. Logistic regressions were used to calculate the odds ratios (ORs) and 95% confidence intervals (95% CIs) for CVD risk factors across stair climbing frequencies. RESULTS: After adjustment for age, sex, lifestyle, and medical conditions, stair climbing >60% of the time, compared to <20% of the time, was inversely associated with obesity, smoking, physical inactivity, and stress: ORs (95% CIs) = 0.63 (0.53, 0.75), 0.81 (0.69, 0.96), 0.48 (0.41, 0.55), and 0.67 (0.58, 0.78), respectively (p-trends < 0.05). CONCLUSION: Stair climbing was inversely associated with obesity, smoking, physical inactivity, and stress; suggesting a potential role for cardiovascular disease prevention.

Benign Mesothelial Cells in transbronchial biopsy specimens: A potential diagnostic pitfall for lung cancer.

Bronchoscopy is a common diagnostic procedure used to identify lung cancer. Specimens acquired through transbronchial biopsy are pivotal in the diagnosis and molecular characterization of this disease. The occurrence of benign mesothelial cells during a transbronchial biopsy (TBB) is relatively rare. Furthermore, these lesions can sometimes be erroneously identified as malignant, potentially resulting in unwarranted or inappropriate treatment for patients with and without lung cancer. In this retrospective analysis, we examined 619 TBB cases at our institute from 2019 to 2021. Benign mesothelial cells were identified via immunohistochemical studies in eight (1.3%) of 619 cases. These cells were classified into three patterns based on their cellular morphology: monolayer, lace, and cobblestone. Recognizing this phenomenon during the procedure is crucial to accurately distinguish benign mesothelial cells from their cancerous counterparts.

The association between the estimated glomerular filtration rate and cognitive impairment: the Suita Study.

This cross-sectional study investigated the association between the estimated glomerular filtration rate (eGFR), a measure of chronic kidney disease (CKD), and cognitive impairment. We used data from 6215 Japanese individuals registered in the Suita Study. Cognitive impairment was defined as a Mini-Mental State Examination (MMSE) score of ≤ 26. Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) of cognitive impairment for eGFR 45-59.9 and < 45 mL/min/1.73 m2 (mild and moderate-to-severe eGFR reductions) compared to eGFR ≥ 60 mL/min/1.73 m2 (normal eGFR). The results showed that both mild and moderate-to-severe eGFR reductions were associated with cognitive impairment: ORs (95% CIs) = 1.49 (1.22-1.83) and 2.35 (1.69-3.26), respectively (p-trend < 0.001). Each increment of eGFR by 10 mL/min/1.73m2 was associated with 4.8% lower odds of cognitive impairment. In conclusion, eGFR reduction was associated with cognitive impairment. Managing CKD is essential for preventing cognitive impairment.

The parental involvement process regarding childhood cancer survivors becoming independent: Focus on balancing health management and social lives from adolescence to adulthood.

AIM: This study aimed to elucidate the parental involvement process regarding childhood cancer survivors' (CCSs') independence while balancing their health management and social lives from adolescence to adulthood to obtain suggestions for long-term support for CCSs and their parents. METHODS: Semi-structured interviews were conducted with 19 parents of Japanese CCSs aged 16-25 years. The data were then qualitatively analyzed using the modified grounded theory approach. RESULTS: Three "categories" and 20 "concepts" were generated. The connections among these categories and concepts revealed the parental involvement process regarding CCSs' independence while balancing their health management and social lives. The first phase in this process is to "support careful behaviors," mainly during CCSs' treatment in the outpatient clinic or shortly after discharge. As CCSs recover after cancer treatment, parents "watch over, but feel conflicted," with "conflicts between protecting their sons/daughters and giving them independence." Then, parents reach a phase in which they "acknowledge and entrust," which includes "acknowledgment of development and efforts" of their sons/daughters, and develop an "attitude to entrust medical checkups to their sons/daughters, along with their preparation." The influencing factors of the three phases include "ongoing anxieties about the late effects of therapy and recurrence" and an "expectation for their sons/daughters to acquire abilities for living independently." CONCLUSIONS: These findings suggest that nurses need to accept parents' feelings and thoughts regarding conflicts with CCSs, recognition of CCSs' development, and values. These processes may help nurses and health-care professionals support parents from a comprehensive perspective.

Medical Cannabis Use Among Canadian Veterans and Non-Veterans: A National Survey.

Background: Medical cannabis (MC) is used by Canadian Veterans to manage a wide range of health issues. However, there is little information comparing the reasons for MC use and its perceived effectiveness between Veterans and non-Veterans. Objects: We compared MC use among a convenience sample of Canadian Veterans and with non-Veteran controls, including demographics, reasons and patterns of use, and perceived effectiveness. Methods: Between November and December 2021, Canadian Veterans using cannabis were invited to participate in a survey using a national press release, social media, and announcements on online platform dedicated to promoting health among Canadian Veterans and non-Veterans during the pandemic (www.MissionVav.com). The survey was also mentioned in a monthly newsletter from Veteran Affairs Canada. Self-reported effectiveness was evaluated using a 0 to 10 visual analogue scale (0 being not all effective, 10 being the most effective). Results: The survey was completed by 157 people, including 108 (69%) males and 49 (31%) females. The mean age was 57 years (range 19 to 84). Among responders, 90 (63%) identified as Veterans. The most common reasons for MC use among Veterans included: insomnia (80%), anxiety (73%), and depression (52%). Veterans reported medical conditions such as chronic pain (88%) and arthritis (51%). Compared with non-Veterans, Veterans were significantly more likely to be male (83% vs. 49%), have a higher BMI (35.2 vs. 30.9), to report problems with sleep, anxiety, depression, and PTSD, and to use cannabis in edible form (51% vs. 22%). Self-reported mean effectiveness scores for MC were highest for PTSD (8.4), insomnia (8.2), anxiety (8.1), depression (8.0), and chronic pain (7.6). Conclusions: We found important differences in user characteristics and cannabis use patterns between Canadian Veterans and non-Veterans. Further controlled studies are required to validate these findings, but these data suggest that orally administered cannabis products may be worth further study.

Comprehensive Study of Anti-UVC Activity and Cytotoxicity of Hot-water Soluble Herb Extracts.

BACKGROUND/AIM: COVID-19 pandemic caused the rapid dissemination of ultraviolet C (UVC) sterilization apparatuses. Prolonged exposure to UVC, however, may exert harmful effects on the human body. The aim of the present study was to comprehensively investigate the anti-UVC activity of a total of 108 hot-water soluble herb extracts, using human dermal fibroblast and melanoma cell lines, for the future development of skin care products. MATERIALS AND METHODS: Exposure time to UVC was set to 3 min, and cell viability was determined using the MTT assay. Anti-UVC activity was determined using the selective index (SI), a ratio of 50% cytotoxic concentration for unirradiated cells to 50% effective concentration that restored half of the UVC-induced decrease of viability. RESULTS: Dermal fibroblasts at any population doubling level were more resistant to UVC irradiation than melanoma cells. Both 49 herb extracts recommended by Japan Medical Herb Association (JAMHA) and 59 additional herb extracts showed comparable anti-UVC activity. SI values of selected herbs (Butterbur, Cloves, Curry Tree, Evening Primrose, Rooibos, Stevia, Willow) were several-fold lower than those of vitamin C and vanillin. Their potent anti-UVC activity was maintained for at least 6 h post irradiation, but declined thereafter to the basal level, possibly due to cytotoxic ingredients. CONCLUSION: UVC sensitivity may be related to the growth potential of target cells. Removal of cytotoxic ingredients of herb extracts may further potentiate and prolong their anti-UVC activity.

Effects of Irradiation by Carbon Dioxide Laser Equipped With a Water Spray Function on Bone Formation in Rat Tibiae.

BACKGROUND/AIM: Irradiation of tissue with carbon dioxide (CO2) laser shows a characteristic thermal effect that causes vaporization of tissue in the target region. However, the thermal effect in places other than the target region induces tissue damage. Two methods are used: high reactive-level laser therapy (HLLT), aimed at surgical treatment, and low reactive-level laser therapy (LLLT), aimed at cell and tissue activation. In both, vaporization of tissue is induced by thermal damage. A water spray function may ameliorate thermal damage from CO2 laser irradiation. In this study, we irradiated CO2 laser on rat tibiae with or without a water spray function and examined the effects of this technique on bone metabolism. MATERIALS AND METHODS: Bone defects were created in rat tibiae by dental bur in a Bur group and by laser in laser irradiation groups with (Spray group) and without (Air group) water spray function. At 1 week postoperatively, histological analyses of tibiae were performed using hematoxylin and eosin staining, immunohistochemical staining (IHC) with anti-sclerostin antibody, and 3-dimensional (3D) observation using micro-computed tomography. RESULTS: Histological findings and 3D observation confirmed induction of new bone formation following laser irradiation in both the Air and Spray groups. No bone formation was seen in the Bur group. IHC revealed that the activity of osteocytes in the region of irradiated cortical bone was markedly impaired in the Air group, but osteocyte impairment was ameliorated in the Spray group and absent in the Bur group. CONCLUSION: The water spray function appears effective in reducing thermal damage to tissues irradiated by CO2 laser. CO2 lasers with water spray function may be useful in bone regeneration therapy.

The process of becoming independent while balancing health management and social life in adolescent and young adult childhood cancer survivors.

AIM: This study aimed to elucidate the process of how adolescent and young adult childhood cancer survivors (CCSs) become independent while balancing health management and social life with a view to providing long-term support. METHODS: Semi-structured interviews were conducted with 22 Japanese CCSs aged 16-25 years. The data were then qualitatively analysed using the modified grounded theory approach. RESULTS: Seven "categories" and 35 "concepts" were generated. The connections among these categories and concepts revealed the process of becoming independent while balancing health management and social life. The first phase in the process is "coordination within constraints," which includes "consciousness and worries about deteriorating health" and "adjustments to balance schoolwork and treatment." This phase changes into "challenges to being free and normal" and "release from constraints." Psychological development then occurs as "gratitude toward surrounding people" and "sustenance from experiencing a rare illness." However, CCSs also "face worries about the persistent effects of cancer," including "awareness of the necessity to continue hospital visits even into adulthood." Through these experiences, CCSs reach the phase of "finding a way to live with oneself," which integrates health management with social life. CONCLUSIONS: These findings may help parents and health, education, and social-care professionals anticipate and share changes in CCSs physical condition, daily life, and psychosocial development. CCSs need support in terms of coordinating cancer therapy and school life, trying what they want to do, self-managing their own health condition, and forming their identity, including making sense of their illness experience.

Comparison of Bitterness Intensity between Prednisolone and Quinine in a Human Sensory Test Indicated Individual Differences in Bitter-Taste Perception.

Prednisolone is a frequently prescribed steroid with a bitter, unpalatable taste that can result in treatment refusal. Oral suspensions or powder dosage forms are often prescribed, particularly to pediatric patients, as they improve swallowability and ease of dose adjustment. Consequently, the bitterness of prednisolone is more apparent in these dosage forms. Few studies have investigated prednisolone's bitterness. Thus, in this study, 50 adults evaluated the bitterness of prednisolone using the generalized Labeled Magnitude Scale (gLMS), in comparison with quinine, a standard bitter substance. Overall, prednisolone-saturated solution demonstrated the same extent (mean gLMS score: 46.8) of bitterness as 1 mM quinine solution (mean gLMS score: 40.1). Additionally, large individual differences were observed in the perception of the bitterness of prednisolone and quinine. Perceived flavors of some drugs are reportedly associated with bitter-taste receptor (TAS2Rs) polymorphisms. Therefore, we investigated the relationship between subjects' genetic polymorphisms of TAS2R19, 38, and 46, and their sensitivity to bitterness. Although a relationship between TAS2R19 polymorphisms and the perception of quinine bitterness was observed, no significant relationship was found between the perceived bitterness of prednisolone and the investigated genes. Ultimately, the results show that despite individual differences among subjects, the cause of prednisolone's strong bitterness is yet to be elucidated.

COVID-19 Vaccine-Associated Lymphadenopathy Mimicking Regrowth of Axillary Lymph Node Metastasis of Lung Adenocarcinoma.

We encountered a woman with re-enlarged axillary lymph nodes during a computed tomography (CT) scan for surveillance of lung adenocarcinoma with axillary lymph node metastasis at the initial diagnosis that had shrunk with standard chemotherapy. We first suspected cancer recurrence and considered a change in the chemotherapeutic regimen. However, after careful history taking regarding the timing of her Coronavirus Disease 2019 (COVID-19) vaccination, and subsequent careful, close follow-up, radiological shrinkage suggested a strictly benign cause. Especially in lung cancer with a medical history of axillary lymph node involvement, cliniciansshould be aware that vaccine-associated lymphadenopathy can mimic cancer recurrence and sometimesprompt serious misjudgment regarding a current treatment course and strategy.

Psychosocial characteristics of victims of special fraud among Japanese older adults: A cross-sectional study using scam vulnerability scale.

Despite the police preventing special fraud victimisation of older adults, both the number of cases and the amount of damage have remained high in Japan. 'Special fraud', in Japan, is a crime in which victims are tricked by fraudsters who through phone or postcards impersonate the victims' relatives, employees and other associates, to dupe the victims of their cash or other valuables. The number of recognised cases of special fraud has been turned to increase in 2021. Although police or consumer affairs administrations have been conducting all-encompassing enlightenment or public education for prevention, it is also necessary to reach out to those who are vulnerable to fraud. In this study, we determine the psychosocial characteristics of victims of special fraud in Japanese older adults. We analysed the age, gender, education, residential status, household satisfaction, risk perception and scam vulnerability scale of 56 older adults aged 60 years or older (mean age: 79.34 ± 7.51 years, 49 women) who had been victims of special fraud and 99 older adults aged 60 years or older (mean age: 77.73 ± 5.69 years, 61 women) who had never been victims of special fraud. The study found that the victimised older adults were more likely to be females who live alone and go out less frequently than the non-victimised older adults. The total scores of the scam vulnerability scale were higher among the elderly victims of special fraud compared to those who had never been scammed, suggesting that the psychosocial characteristics of victims of special fraud among older adults are being female, living alone, going out infrequently, having high confidence against fraud victimisation and responding quickly to phone calls and unknown visitors. Therefore, government agencies or family members should take care of older women who meet these characteristics to reduce their contact with fraudsters.

CD8+ T-cell Responses Are Boosted by Dual PD-1/VEGFR2 Blockade after EGFR Inhibition in Egfr-Mutant Lung Cancer.

Epidermal growth factor receptor (EGFR) is the most frequently mutated driver oncogene in nonsmoking-related, non-small cell lung cancer (NSCLC). EGFR-mutant NSCLC has a noninflamed tumor microenvironment (TME), with low infiltration by CD8+ T cells and, thus, immune-checkpoint inhibitors, such as antiprogrammed cell death-1 (anti-PD-1), have weak antitumor effects. Here, we showed that CD8+ T-cell responses were induced by an EGFR-tyrosine kinase inhibitor (TKI) in syngeneic Egfr-mutant NSCLC tumors, which was further pronounced by the sequential dual blockade of PD-1 and vascular endothelial growth factor receptor 2 (VEGFR2). However, the simultaneous triple blockade had no such effect. The PD-1/VEGFR2 dual blockade did not exert tumor-inhibitory effects without pretreatment with the EGFR-TKI, suggesting that the treatment schedule is crucial for the efficacy of the dual blockade therapy. Pretreatment with EGFR-TKI increased the CD8+ T-cell/regulatory T-cell (Treg) ratio, while also increasing the expression of immunosuppressive chemokines and chemokine receptors, as well as increasing the number of M2-like macrophages, in the TME. Discontinuing EGFR-TKI treatment reversed the transient increase of immunosuppressive factors in the TME. The subsequent PD-1/VEGFR2 inhibition maintained increased numbers of infiltrating CD8+ T cells and CD11c+ dendritic cells. Depletion of CD8+ T cells in vivo abolished tumor growth inhibition by EGFR-TKI alone and the sequential triple therapy, suggesting that EGFR inhibition is a prerequisite for the induction of CD8+ T-cell responses. Our findings could aid in developing an alternative immunotherapy strategy in patients with cancers that have driver mutations and a noninflamed TME.

Massive hemoptysis in a post-operative patient with recurrent lung cancer successfully treated by the combination therapy of Endobronchial Watanabe Spigot and bronchial artery embolization.

A 76-year-old woman who was treated with lorlatinib for postoperative recurrent anaplastic lymphoma kinase-positive lung adenocarcinoma visited our hospital with massive hemoptysis. Chest computed tomography showed massive bleeding from the right upper lobe; however, the cause of bleeding was unclear. After bronchial artery embolization (BAE), bronchial occlusion was performed using an Endobronchial Watanabe Spigot (EWS) that was easily placed because BAE had reduced the bleeding volume. Treatment with BAE alone was inadequate; however, additional therapy with EWS after BAE successfully controlled the massive hemoptysis, especially in this patient who underwent lobectomy to prevent respiratory dysfunction.

Successful and Prompt Treatment with Tepotinib for Lung Adenocarcinoma Harboring MET Exon 14 Skipping Mutation Combined with Lung Abscess Formation: A Case Report.

Tepotinib, the novel MET-tyrosine kinase inhibitor, shows an antitumor effect for patients with non-small-cell lung cancer (NSCLC) harboring MET exon 14 skipping mutation. In January 2022, the AmoyDx® Pan Lung Cancer polymerase chain reaction Panel (AmoyDx® panel), which had a shorter turnaround time than the conventional test, was launched in Japan as a tepotinib companion test. We report a patient with an advanced MET-mutant NSCLC promptly diagnosed using the AmoyDx® panel and successfully treated with tepotinib. Although the patient's performance status (PS) worsened due to the rapid tumor progression and lung abscess formation, the tumor shrank immediately after tepotinib treatment with marked PS improvement.

Pembrolizumab in advanced NSCLC patients with poor performance status and high PD-L1 expression: OLCSG 1801.

BACKGROUND: The role of pembrolizumab in the treatment of poor performance status (PS) patients remains unclear. PATIENTS AND METHODS: We conducted a phase II trial to investigate the efficacy and safety of pembrolizumab as first-line therapy for non-small-cell lung cancer (NSCLC) patients with PSs of 2-3 and programmed cell death ligand 1 (PD-L1) expression ≥ 50%. The primary endpoint of this study was the objective response rate (ORR). RESULTS: Fourteen patients treated at eight institutions were enrolled. Most patients had PS 2 (12/14; 86%) and others had PS 3 (2/14; 14%). The ORR was 57.1% (95% confidence interval 28.9-82.3%), which met the primary endpoint. The median progression-free survival (PFS) and 1-year PFS rates were 5.8 months and 20.0%, respectively. At the time of data cut-off, one patient had received treatment for more than 1 year; another patient had received treatment for more than 2 years. Nine patients had improved PS with treatment (Wilcoxon signed-rank test, p = 0.003). Two patients had immune-related adverse events ≥ grade 3: grades 5 and 3 elevation in alanine and aspartate aminotransferases. Two PS 3-stage patients were diagnosed with clinically progressive disease prior to initial computed tomography; both died within 2 months. CONCLUSION: Pembrolizumab was effective for the treatment of NSCLC patients with a poor PS and PD-L1 level ≥ 50%. However, given the poor outcomes of the PS 3 patients, the drug is not indicated for such patients. Adverse events, including liver dysfunction, should be carefully monitored.

Diagnostic performance and neural basis of the combination of free- and pre-drawn Clock Drawing Test.

OBJECTIVES: This study aimed to clarify the diagnostic performance and neural basis of the Clock Drawing Test (CDT) combining free- and pre-drawn methods. METHODS: This retrospective study included 165 participants (91 with Alzheimer disease [AD], 52 with amnestic mild cognitive impairment [aMCI], and 22 healthy controls [HC]), who were divided into four groups according to their free- and pre-drawn CDT scores: group 1, could do both; group 2, impaired in both; group 3, impaired in pre-drawn CDT; and group 4, impaired in free-drawn CDT. The diagnostic performances of the free-drawn, pre-drawn, and combination methods were compared using receiver operating characteristics analysis; in voxel-based morphometry analysis, the gray matter (GM) volume of groups 2-4 were compared with that of group 1. RESULTS: The area under the curve of the combination method was greater than that of the free- or pre-drawn method alone when comparing AD with HC or aMCI. Group 2 had a significantly smaller GM volume in the bilateral temporal lobes than group 1. Group 3 had a trend toward smaller GM volumes in the right temporal lobe when a liberal threshold was applied. Group 4 had significantly smaller GM volumes in the left temporal lobe than group 1. CONCLUSIONS: This study suggests that the combination method may be able to screen for a wider range of brain dysfunction. Combined use of free- and pre-drawn CDT may be useful for screening for AD and its early detection and treatment.

Pulmonary Aspergilloma and Allergic Bronchopulmonary Aspergillosis Following the 2018 Heavy Rain Event in Western Japan.

A 16-year-old boy with asthma participated in recovery volunteer work following the 2018 heavy rains in Japan. One month later, he experienced chest pain and dyspnea. Chest computed tomography revealed a cavity with a fungal ball, and Aspergillus fumigatus was detected in his bronchoalveolar lavage fluid. He was treated with voriconazole, but new consolidations appeared rapidly. He also experienced allergic bronchopulmonary aspergillosis. After prednisolone prescription, the consolidations improved; however, his asthma worsened. He underwent partial lung resection to avoid allergens, and his symptoms improved. We must recognize cases of infection after a disaster, especially in patients with chronic respiratory diseases.

Transformed diffuse large B-cell lymphoma from marginal zone lymphoma in the anterior mediastinum: A case report and review of the literature.

Marginal zone lymphoma (MZL) arising from the anterior mediastinum is rare. In the majority of reported cases, the tumor was incidentally discovered, reflecting its indolent clinical features. We present a 38-year-old woman who had no medical history, and presented with a bulky anterior mediastinal tumor complicated by life-threatening compression of the vasculature and bronchi. Biopsy specimens of the neoplasm suggested transformed diffuse large B-cell lymphoma (DLBCL) from MZL. To our best knowledge, this is the first case report of anterior mediastinum MZL associated with an aggressive clinical course and life-threatening complications likely due to transformation to DLBCL.

Triple therapy with osimertinib, bevacizumab and cetuximab in EGFR-mutant lung cancer with HIF-1α/TGF-α expression.

Osimertinib, a third generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, is the standard treatment for patients with lung cancer harboring EGFR T790M; however, acquired resistance is inevitable due to genetic and epigenetic changes in cancer cells. In addition, a recent randomized clinical trial revealed that the combination of osimertinib and bevacizumab failed to exhibit superior progression-free survival compared with osimertinib alone. The present study aimed to investigate the effect of triple therapy with osimertinib, bevacizumab and cetuximab in xenograft tumors with different initial tumor volumes (conventional model, 200 mm3 and large model, 500 mm3). The results demonstrated that osimertinib significantly inhibited tumor growth in both the conventional and large models; however, maximum tumor regression was attenuated in the large model in which hypoxia-inducible factor-1α (HIF-1α) and transforming growth factor-α (TGF-α) expression levels increased. Although the combination of osimertinib and bevacizumab exerted a greater inhibitory effect on tumor growth compared with osimertinib in the conventional model, the effect of this combination therapy was attenuated in the large model. TGF-α attenuated sensitivity to osimertinib in vitro; however, this negative effect was counteracted by the combination of osimertinib and cetuximab, but not osimertinib and bevacizumab. In the large xenograft tumor model, the triple therapy induced the greatest inhibitory effect on tumor growth compared with osimertinib alone and its combination with bevacizumab. Clinical trials of the triple therapy are required for patients with lung cancer with EGFR mutations and HIF-1α/TGF-α.

Anxiety Impacts Consent Capacity to Treatment in Alzheimer's Disease.

This study aimed to clarify how behavioral and psychological symptoms of dementia (BPSD) and cognitive function affect the decision-making capacity of persons with Alzheimer's disease (AD) in a real informed consent situation about anti-dementia drug prescriptions. The participants were 76 patients with AD. We used the MacArthur Competence Assessment Tool to assess the capacity for consent to treatment (MacCAT-T). We simultaneously used the Mini-Mental State Examination, Executive Interview, Executive Clock Drawing Task, Logical Memory I of the Wechsler Memory Scale-Revised (LM I), LM II, and Neuropsychiatric Inventory (NPI) to assess cognitive function and psychiatric symptoms. We calculated the correlations between the MacCAT-T scores and the demographic, neuropsychological, and psychiatric variables. Once the univariable correlations were determined, we performed simple linear regression analyses to examine if the regression equations were significant. In the final analyses, we incorporated significant variables into stepwise multiple linear regression analyses to determine the most significant predictors of mental capacity. Age (ß = -0.34), anxiety (ß = -0.27), and LM I (ß = 0.26) were significant predictors of "understanding" (adjusted R 2 = 0.29). LM II (ß = 0.39), anxiety (ß = -0.29), and education (ß = 0.21) were significant predictors of "understanding of alternative treatments" (adjusted R 2 = 0.30). Anxiety (ß = -0.36) and age (ß = -0.22) were significant predictors of "appreciation" (adjusted R 2 = 0.18). Age (ß = -0.31) and anxiety (ß = -0.28) were significant predictors of explained variance in "reasoning" (adjusted R 2 = 0.17). Patients with anxiety had lower scores on all five MacCAT-T subscales: "understanding," without 3.8 [SD = 1.2] vs. with 2.6 [SD = 1.1]; "understanding of alternative treatments," without 2.9 [SD = 2.2] vs. with 1.3 [SD = 1.8]; "appreciation," without 2.9 [SD = 1.1] vs. with 1.9 [SD = 1.2]; "reasoning," without 4.0 [SD = 2.0] vs. with 2.7 [SD = 1.7]; and "expressing a choice," without 1.9 [SD = 0.4] vs. with 1.5 [SD = 0.6]. Considering the effects of BPSD, cognitive function, and age/education when assessing consent capacity in persons with AD is important. Reducing anxiety may contribute to improved capacity in persons with AD.
