RESUMEN

INTRODUCTION: This study aimed to investigate the influence of case management and its corresponding computer-assisted assessment system on the quality improvement of dementia care. METHODS: This observational study enrolled 2029 patients and their caregivers at Changhua Christian Hospital in Taiwan. Physicians who made the diagnosis of dementia would introduce the patient and caregiver dyad to the case manager-centered collaborative care team after obtaining agreement. The achievement rates of 11 quality indicators (QIs) comprising timely diagnostic evaluations, regular screens of cognition and neuropsychiatric symptoms, caregiver support, and proper medication prescriptions were counted. Different timeframes (≤4 months, 4 months-1 year, 1-2 years, 2-3 years, or ≥3 years) from diagnosis of dementia to collaborative care intervention were compared. RESULTS: A significantly higher attainment rate was achieved for patients with earlier entry into the collaborative team model, including QIs about timely diagnosis and regular screening, and caregiver support. The QIs regarding dementia medication prescriptions and documentation of the risk of antipsychotics remained similar regardless of the time of entry into the model. The completion rates of QIs also improved after the information system was launched. CONCLUSIONS: Physician-case manager co-management in the setting of a collaborative care model with a computer-assisted assessment system helps improve QI achievement for dementia care.

RESUMEN

BACKGROUND: Sentinel lymph node biopsy (SLNB) is the standard of care for axillary staging in early breast cancer patients with low-burden axillary metastasis (≤ 2 positive nodes). This study aimed to determine the diagnostic performances of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) and breast magnetic resonance imaging in detecting axillary lymph node (ALN) metastases and the reliability to predict ALN burden. METHODS: A total of 275 patients with primary operable breast cancer receiving preoperative PET/CT and upfront surgery from January 2001 to December 2022 in a single institution were enrolled. A total of 244 (88.7%) of them also received breast MRI. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of PET/CT and breast MRI were assessed. The predictive values to determine ALN burden were evaluated using radio-histopathological concordance. RESULTS: PET/CT demonstrated a sensitivity of 53.4%, specificity of 82.1%, PPV of 65.5%, NPV of 73.5%, and accuracy of 70.9% for detecting ALN metastasis, and the corresponding values for MRI were 71.8%, 67.8%, 56%, 80.8%, and 69.2%, respectively. Combining PET/CT and MRI showed a significantly higher PPV than MRI (72.7% vs 56% for MRI alone, p = 0.037) and a significantly higher NPV than PET/CT (84% vs 73.5% for PET/CT alone, p = 0.041). For predicting low-burden axillary metastasis (1-2 positive nodes), the PPVs were 35.9% for PET/CT, 36.7% for MRI, and 55% for combined PET/CT and MRI. Regarding patients with 0-2 positive ALNs in imaging, who were indicated for SLNB, the predictive correctness was 96.1% for combined PET/CT and MRI, 95.7% for MRI alone, and 88.6% for PET/CT alone. CONCLUSIONS: PET/CT and breast MRI exhibit high predictive values for identifying low-burden axillary metastasis in patients with operable breast cancer with ≦ 2 positive ALNs on imaging.

RESUMEN

BACKGROUND: This study aimed to explore the association between adherence of collaborative care model and short-term deterioration of BPSD after controlling patient and caregiver factors. METHODS: This retrospective case-control study enrolled 276 participants who were newly diagnosed with dementia and BPSD. A dementia collaborative care team interviewed patients and caregivers to form a care plan and provided individualized education or social resource referrals. A multivariate logistic regression model with backward selection was used to test factors associated with BPSD deterioration, defined as worse neuropsychiatric inventory (NPI) scores 1 year after joining the care model. RESULTS: Male sex (odds ratio [OR] = 0.45; 95% confidence interval [CI] = 0.25-0.84) and higher clinical dementia rating scale sum of boxes scores (CDR-SOB) (OR = 0.90; 95% CI = 0.83-0.98) were protective factors, whereas spouse caregivers and withdrawals from the care model (OR = 3.42; 95% CI = 1.28-9.15) were risk factors for BPSD deterioration. CONCLUSIONS: Our study showed that both patient and caregiver factors were associated with deterioration of BPSD. The case manager-centered dementia collaborative care model is beneficial for the management of BPSD. Healthcare systems may consider implementing a case management model in clinical dementia care practice.

RESUMEN

BACKGROUND: There is an intimate spatial relationship between the cardiovascular and airway structures. Central airway compression related to congenital cardiovascular anomalies should be considered in neonates, infants, and young children presenting with stridor. METHODS: From July 31, 1990 to December 31, 2018, 24 pediatric patients, including 18 males and 6 females, aged 1 day to 11.3 years old, presenting with stridor and/or lip cyanosis were enrolled in this study. At presentation, none of the patients had a known history of congenital heart disease. Patients with congenital bronchopulmonary vascular/foregut malformations, congenital pulmonary venolobar syndrome, congenital pulmonary malinosculations, Eisenmenger syndrome, secondary pulmonary hypertension, and idiopathic pulmonary arterial hypertension were excluded from this study. Available profiles of 24 patients were reviewed and the underlying congenital cardiovascular anomalies contributing to the clinical manifestation of stridor were analyzed, including chart recordings, chest radiograms, echocardiograms, computerized tomography, electrocardiograms, esophagograms, cardiac catheterization, magnetic resonance imaging, and bronchography. RESULTS: Stridor was an early sign of congenital cardiovascular anomalies, including double aortic arch, right aortic arch (RAA) with Kommerell diverticulum, mirror-image right aortic arch with aortic diverticulum, anomalous right innominate artery, left pulmonary artery sling, RAA with tetralogy of Fallot and persistent fifth aortic arch, a vertical patent ductus arteriosus from a transverse left aortic arch, and absent pulmonary valve syndrome. Notably, chest radiography provided the first clue of RAA in 18 of the 24 patients. CONCLUSIONS: Stridor can be a harbinger of congenital cardiovascular anomalies causing central airway compression in pediatric patients.

RESUMEN

Concurrent involvement of bilateral renal and cerebral arteries, usually incurred as stenosis, is rare in childhood-onset Takayasu arteritis (c-TA). We report the case of a 14-year-old girl, with c-TA, presenting with transient ischemic attack after endovascular revascularization for renal artery stenosis and cerebrovascular stroke after surgical revascularization for cerebral artery stenosis associated with childhood-onset moyamoya syndrome. We deem that decrease of blood pressure by endovascular revascularization and improvement of cerebral perfusion by surgical revascularization may have jeopardized the cerebral deep watershed zone to cerebral ischemia followed by cerebral hyperperfusion syndrome and caused transient ischemic attack and cerebrovascular stroke in our patient. Revascularization could be a double-edge sword for c-TA patients presenting with concomitant renal artery stenosis and cerebral artery stenosis, and should be performed with caution. Quantitative analysis of cerebral blood flow by brain magnetic resonance imaging and angiography should be performed within 48 hours after surgical revascularization in c-TA.

RESUMEN

This study investigated the anticancer effects of N-farnesyloxy-norcantharimide (NOC15), a newly synthesized norcantharidin (NCTD) analogue, on human leukemic Jurkat T cells and the signaling pathway underlying its effects. We found that the half maximal inhibitory concentration (IC50) of NOC15 on Jurkat T cells is 1.4 µmol/l, which is 11.14-fold (=15.6÷1.4) smaller than the 15.6 µmol/l of NCTD on Jurkat T cells, whereas the IC50 of NOC15 on human normal lymphoblast (HNL) is 207.9 µmol/l, which is 8.17-fold (=1698.0÷207.8) smaller than the 1698.0 µmol/l of NCTD on HNL cells. These results indicated that NOC15 exerts a higher anticancer effect on Jurkat T cells and has higher toxicity toward HNL cells than NCTD. Thus, NOC15 is 1.36-fold (=11.14÷8.17) beneficial as an anticancer agent toward Jurkat T cells compared with NCTD. Moreover, NOC15 can increase the percentage of cells in the sub-G1 phase and reduce the cell viability of Jurkat T cells, stimulate p38 and extracellular signal-regulated protein kinase 1/2 (ERK1/2) of mitogen-activated protein kinases (MAPKs) signaling pathway, and inhibit calcineurin expression and interleukin-2 (IL-2) production. However, NOC15 exerted no effects on the Jun-N-terminal kinase 1/2 (JNK1/2) signaling pathway, the production of IL-8, and tumor necrosis factor-α. We conclude that the anticancer activity of the newly synthesized NOC15 is 1.36-fold beneficial than NCTD as an anticancer agent and that NOC15 can increase the percentage of cells in the sub-G1 phase through the stimulation of p38 and ERK1/2 of the MAPK signaling pathway and the inhibition of calcineurin expression and IL-2 production. The NOC15 may have the potential of being developed into an anticancer agent in the future.

RESUMEN

This study investigated the anticancer effects of two newly synthesized norcantharidin analogs, N-farnesyloxy-norcantharimide (NOC15) and N-farnesyl-norcantharimide (NC15), in L1210 cells and in a syngeneic mouse leukemia model (L1210 cell line plus DBA/2 mice). We found that the half-maximal inhibitory concentration (IC50) of NOC15 and NC15 on L1210 cells is 1.56 and 2.62 µmol/l, respectively, and that the IC50 of NOC15 and NC15 on human normal lymphoblast is 207.9 and 2569 µmol/l, respectively. In cell cycle analysis, NOC15 could increase the sub-G1 phase, whereas NC15 could induce G2/M arrest. Annexin-V apoptosis assay indicated that both NOC15 and NC15 could induce cell apoptosis. In the syngeneic mouse leukemia model, both NOC15 and NC15 could increase the survival days of mice and decrease the tumor weight. Moreover, both NOC15 and NC15 could retard the increase in peripheral blood leukocyte count due to L1210 cells. In the subcutaneous (s.c.) group, the treatment with NOC15 could retard the decrease in the weight of the liver and the spleen caused by L1210 cells, whereas the treatment with NC15 could retard the decrease in the weight of the spleen caused by L1210 cells. We conclude that the new compounds NOC15 and NC15 have strong anticancer activity and low toxicity both in vitro and in vivo. NOC15 and NC15 may have the potential to be developed into anticancer agents in the future.

RESUMEN

BACKGROUND: The aim of this study was to compare the diagnostic value of 18F-FDG PET or PET/CT with FDG PET/MR in patients with inflammatory bowel disease (IBD). METHODS: A comprehensive search was performed in PubMed for studies reporting the diagnostic performance of FDG PET (PET/CT) and FDG PET/MR in IBD from the inception of the database to March 14, 2024, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fourteen studies were included in this systematic review and meta-analysis. Pooled estimates of segment-based sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio for FDG PET (PET/CT) and FDG PET/MR were calculated alongside 95% confidence intervals. Summary receiver operating characteristic (SROC) curves were plotted, and the area under the SROC curve was determined alongside the Q* index. RESULTS: The segment-based pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the SROC curve of FDG PET (PET/CT) for diagnosing IBD (9 studies) were 0.81, 0.86, 5.76, 0.22, 31.92, and 0.92, respectively. Those of FDG PET/MR (5 studies) were 0.78, 0.92, 10.97, 0.25, 51.79, and 0.95. There was no significant difference in the abilities of detecting or excluding IBD between FDG PET (PET/CT) and FDG PET/MR. CONCLUSIONS: For diagnostic value in patients with IBD, there was no significant difference between FDG PET (PET/CT) and FDG PET/MR. Both FDG PET (PET/CT) and FDG PET/MR have demonstrated high diagnostic performance for accurate diagnosing in patients with IBD.

RESUMEN

Background: To compare short-term cognitive outcomes among groups with and without neuropsychiatric symptoms (NPSs) or antipsychotic prescription and to determine which disease status or treatment modality is associated with relatively faster cognitive decline. Methods: We retrospectively analyzed a prospective cohort of patients diagnosed with dementia and mild cognitive impairment. All participants were evaluated using the Cognitive Abilities Screening Instrument (CASI) during their initial clinical assessments and at the annual follow-up. The dependent variable was annual delta CASI. Multivariate linear regression analysis was used to assess the degree of association between NPS, antipsychotic use, and cognitive decline after adjusting for confounding factors. Neuropsychiatric symptoms were examined individually to determine their predictive value for cognitive decline. Results: A total of 407 (N = 407) patients were included in the study. NPSs, rather than antipsychotic use, led to faster cognitive decline. A higher baseline NPI total score predicted a significantly faster decline in CASI scores (1-year delta CASI = -0.22, 95% CI = -0.38~ -0.05, p = 0.010). Specific items (delusions, agitation, depression, anxiety, euphoria, and apathy) in the NPS significantly increased cognitive decline. Conclusion: Certain neuropsychiatric symptoms, rather than antipsychotic use, lead to faster cognitive decline in a dementia collaborative care model. Checking for and providing appropriate interventions for NPS in people with dementia and their caregivers are highlighted.

RESUMEN

PURPOSE: Gated single photon emission computed tomography (SPECT) using thallium-201 (Tl-201) has the capacity to evaluate the earlier post-stress (PS) function compared to technetium-99m labeled tracers, and may be more sensitive in detecting transient ventricular dysfunction caused by stress-induced ischemia. The purpose of this study was to assess the prognostic value of functional variables obtained from Tl-201 gated SPECT as a predictor of major adverse cardiac events (MACE). METHODS: Four hundred and thirty-eight subjects who had known or suspected coronary artery disease and underwent clinically indicated dipyridamole-stress electrocardiography-gated Tl-201 SPECT were included in this study. Functional variables, including PS-ejection fraction (EF), PS-end systolic volume (ESV), PS-regional wall motion abnormality (RWA), reversible RWA and EF worsening, were generated to study the correlation with MACE (cardiac death, nonfatal infarction, unstable angina and coronary revascularization). RESULTS: Sixty-eight of the total 438 patients (15.5%) had MACE during the period of follow-up (a median time of 31 months), including 2 cardiac deaths, 9 non-fatal infarctions, 9 unstable angina and 48 coronary revascularizations. These events occurred significantly more frequently in patients with reversible RWA (28.8% vs. 7.1%, p < 0.0001), EF worsening (34.8% vs. 12.1%, p < 0.0001), PS-RWA (29.9% vs. 11.4%, p < 0.0001) and PS-EF < 45% (27.8% vs. 14.4%, p = 0.034). Using the Cox proportional hazards regression analysis, reversible RWA and EF worsening were two independent predictors of MACE, providing incremental prognostic value over clinical and perfusion-alone information. CONCLUSIONS: The functional assessment with Tl-201 gated SPECT was a useful prognosticator for patients who had known or suspected coronary artery disease. KEY WORDS: Coronary artery disease; Gated SPECT; Major adverse cardiac events; Tl-201.

RESUMEN

Background: Optimal use of psychotropic medications for people living with dementia is important. By finding potentially modifiable factors, dementia care teams may find solutions to achieve the appropriate use of psychotropic drugs. Objective: This study aimed to elucidate patient and caregiver factors associated with the use of psychotropic drugs listed in the potentially inappropriate medications (PIMs) in community-dwelling people with dementia. Methods: This cross-sectional study enrolled 808 patients newly diagnosed with dementia, and their caregivers, from a dementia clinic at Changhua Christian Hospital. Patient and caregiver characteristics, care mode, and social resource usage were recorded. Multivariate logistic regression was used to identify factors associated with prescribing psychotropic medications. Results: Of all the participants, 39.1% used at least one of psychotropic medication categorized as PIM. Patients with frontotemporal dementia, with behavior or psychological symptoms, or cared by sole foreign care workers; caregivers with higher depression scores, employed or non-spouse caregivers carried a higher risk of prescription of psychotropic medications listed in PIMs. Conclusion: Psychotropic drug prescriptions are associated with patient and caregiver factors. Therefore, implementing appropriate interventions, especially those targeting potentially modifiable factors, is important to reduce psychotropic medication use.

RESUMEN

PURPOSE: In (201)Tl SPECT myocardial perfusion imaging (MPI) data are acquired shortly after the stress injection to assess early post-stress left ventricle (LV) function. The purpose of this study was to use (201)Tl SPECT MPI to investigate whether stress-induced myocardial ischemia is associated with LV mechanical dyssynchrony. METHODS: Enrolled in the study were 75 patients who were referred for dipyridamole stress and rest (201)Tl gated SPECT MPI. The early post-stress scan was started 5 min after injection, and followed by the rest scan 4 h later. The patients were divided into three groups: ischemia group (N = 25, summed stress score, SSS, ≥5, summed rest score, SRS, <5), infarct group (N = 16, SSS ≥5, SRS ≥5) and normal group (N = 34, SSS <5, SRS <5). LV dyssynchrony parameters were calculated by phase analysis, and compared between the stress and rest images. RESULTS: In the ischemia group, LV dyssynchrony was significantly larger during stress than during rest. On the contrary, LV dyssynchrony during stress was significantly smaller than during rest in the normal and infarct groups. LV dyssynchrony during rest was significantly larger in the infarct group than in the normal and ischemia groups. There were no significant differences in LV dyssynchrony during rest between the normal and ischemia groups. CONCLUSION: Stress-induced myocardial ischemia caused dyssynchronous contraction in the ischemic region, leading to a deterioration in LV synchrony. Normal myocardium had more synchronous contraction during stress. The different dyssynchrony pattern between ischemic and normal myocardium early post-stress may aid the diagnosis of coronary artery disease using (201)Tl gated SPECT MPI.

RESUMEN

BACKGROUND: The global population with dementia is growing rapidly. Dementia patients have been included in the services of the long-term care Act 2.0, supported by Taiwan's government since 2017. Community aging care centers are extensively established, which are places providing social connections and group physical and cognitive training programs for elderly people. OBJECTIVE: To elucidate the efficacy of community aging care centers on cognitive function in people with dementia. METHODS: A total of 1,277 patients with dementia diagnosed at the Changhua Christian Hospital outpatient departments were enrolled. A total of 113 patients who used community aging care centers and 452 subjects matched for age, education, and initial score of clinical dementia rating scale sum of boxes (CDR-SOB) control group were analyzed. The primary outcome was the change in CDR-SOB scores before and after utilization of community aging care centers. RESULTS: The mean annual change of CDR-SOB scores were 1.72±2.97, 1.08±2.36, and 1.04±3.64 in control, Community Service Centers for Dementia, and community elderly stations, respectively, after about 1.5 years follow-up. Patients with dementia using community aging care centers had significantly less progression in CDR-SOB scores than those in the control group (-0.65; 95% CI: -1.27, -0.03; p = 0.041). Using one more day of community aging care centers per week significantly promotes 0.16 points of CDR-SOB decline (-0.16, 95% CI: -0.31; -0.00; p = 0.045). CONCLUSION: Community aging care centers, based on the long-term care Act 2.0 in Taiwan, were effective in delaying the decline in global function in people living with dementia.

RESUMEN

This research used DeepLab v3 + -based semantic segmentation to automatically evaluate the platelet activation process and count the number of platelets from scanning electron microscopy (SEM) images. Current activated platelet recognition and counting methods include (a) using optical microscopy or SEM images to identify and manually count platelets at different stages, or (b) using flow cytometry to automatically recognize and count platelets. However, the former is time- and labor-consuming, while the latter cannot be employed due to the complicated morphology of platelet transformation during activation. Additionally, because of how complicated the transformation of platelets is, current blood-cell image analysis methods, such as logistic regression or convolution neural networks, cannot precisely recognize transformed platelets. Therefore, this study used DeepLab v3 + , a powerful learning model for semantic segmentation of image analysis, to automatically recognize and count platelets at different activation stages from SEM images. Deformable convolution, a pretrained model, and deep supervision were added to obtain additional platelet transformation features and higher accuracy. The number of activated platelets was predicted by dividing the segmentation predicted platelet area by the average platelet area. The results showed that the model counted the activated platelets at different stages from the SEM images, achieving an error rate within 20%. The error rate was approximately 10% for stages 2 and 4. The proposed approach can thus save labor and time for evaluating platelet activation and facilitate related research.

RESUMEN

This study aimed to examine the institutionalization rate in patients with dementia in Taiwan, identify the predictors of institutionalization, and conduct a mediation analysis of caregiver burden between neuropsychiatric symptoms and institutionalization. We analyzed data from a retrospective cohort registered in dementia collaborative care (N = 518). The analyses applied univariate and multivariate Cox proportional hazard regression with Firth's penalized likelihood to assess the relationship between each predictor at entry and institutionalization for survival analysis. Thirty (5.8%) patients were censored due to institutionalization after a median follow-up of one-and-a-half years. Neuropsychiatric symptoms, loss of walking ability, and living alone predicted institutionalization. Caregiver burden may partially mediate the effects of neuropsychiatric symptoms and institutionalization. High caregiver burden due to presence of neuropsychiatric symptoms may partially contribute to institutionalization among people living with dementia in Taiwan. However, proper management of neuropsychiatric symptoms and caregiver empowerment may ameliorate institutionalization risk.

RESUMEN

PURPOSE: The aim of this study was to elucidate the factors and caring scenarios associated with a moderate to severe care burden in the caregivers of patients with vascular cognitive impairment (VCI). PATIENTS AND METHODS: This cross-sectional study included 158 patients with VCI and their caregivers who were managed by the dementia collaborative care team at Changhua Christian Hospital, Taiwan. Gender, age, clinical dementia rating, walking ability, behavioral symptoms, and psychological symptoms were the variables from the patients with VCI. Age, marital status, relation to the VCI patient, education, employment status, help of key activities, type of primary care, frequency of care, ZBI (Zarit burden interview) caregiving burden, and caregiver's mood were the evaluated variables for the caregivers. The Apriori algorithm was used to identify the attributes that resulted in different caregiving burdens from a comprehensive viewpoint of both VCI patients and their caregivers. RESULTS: A total of 1193 rules were identified with 1134 rules belonging to caregivers with a mild to moderate burden and 59 rules belonging to caregivers with a moderate to severe burden. Seven general rules were created based on a summary of these 59 rules. The results showed that an employed female caregiver who was taking care of her husband alone for ≥6 days per week, and who was helping with all key activities was likely to experience a moderate to severe burden when the patient had VCI. Moreover, if the caregiver had a relatively low education level and expressed an abnormal mood during the assessment, this increased the likelihood of the caregiver having a moderate to severe burden. CONCLUSION: The caregiver's gender, relation to the care recipient, education level, mood status, employment status, and care loading were associated with a higher burden of care for caregivers of patients with VCI. Therefore, a dementia care team should provide personalized training for caregivers about the disease, care skills for specific behaviors and psychological symptoms of dementia (BPSD), and strategies to cope with their own feelings. Caregivers should also be referred to appropriate social resources, such as support groups or respite care.
