RESUMO

The most effective drug, doxorubicin (DOX), is widely used worldwide for clinical application as an anticancer drug. DOX-induced cytotoxicity is characterized by mitochondrial dysfunction. There is no alternative treatment against DOX-induced cardiac damage despite intensive research in the present decades. Ohwia caudata has emerged as a potential herbal remedy that prevents from DOX-induced cytotoxicity owing to its pharmacological action of sustaining mitochondrial dynamics by attenuating oxidative stress and inducing cellular longevity. However, its underlying mechanisms are unknown. The novel treatment provided here depends on new evidence from DOX-treated H9c2 cells, which significantly enhanced insulin-like growth factor (IGF) II receptor (IGF-IIR) pathways that activated calcineurin and phosphorylated dynamin-related protein 1 (p-Drp1) at ser616 (p-Drp1[ser616]); cells undergo apoptosis due to these factors, which translocate to mitochondria and disrupt their function and integrity, and in terms of herbal medicine treatment, which significantly blocked these phenomena. Thus, our findings indicate that maintaining integrity of mitochondria is an essential element in lowering DOX-induced cytotoxicity, which further emphasizes that our herbal medicine can successfully block IGF-IIR pathways and could potentially act as an alternative mechanism in terms of cardioprotective against doxorubicin.

RESUMO

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease affecting approximately 1% of the global population, with a higher prevalence in women than in men. Chronic inflammation and oxidative stress play pivotal roles in the pathogenesis of RA. Anethole, a prominent compound derived from fennel (Foeniculum vulgare), possesses a spectrum of therapeutic properties, including anti-arthritic, anti-inflammatory, antioxidant, and tumor-suppressive effects. However, its specific impact on RA remains underexplored. This study sought to uncover the potential therapeutic value of anethole in treating RA by employing an H2 O2 -induced inflammation model with HIG-82 synovial cells. Our results demonstrated that exposure to H2 O2 induced the inflammation and apoptosis in these cells. Remarkably, anethole treatment effectively countered these inflammatory and apoptotic processes triggered by H2 O2 . Moreover, we identified the aquaporin 1 (AQP1) and protein kinase A (PKA) pathway as critical regulators of inflammation and apoptosis. H2 O2 stimulation led to an increase in the AQP1 expression and a decrease in p-PKA-C, contributing to cartilage degradation. Conversely, anethole not only downregulated the AQP1 expression but also activated the PKA pathway, effectively suppressing cell inflammation and apoptosis. Furthermore, anethole also inhibited the enzymes responsible for cartilage degradation. In summary, our findings highlight the potential of anethole as a therapeutic agent for mitigating H2 O2 -induced inflammation and apoptosis in synovial cells, offering promising prospects for future RA treatments.

RESUMO

Metabolic-associated fatty liver disease (MAFLD) is a global concern, often undetected until reaching an advanced stage. Palmitic acid (PA) is a type of fatty acid that increases and leads to liver apoptosis in MAFLD. However, there is currently no approved therapy or compound for MAFLD. Recently, branched fatty acid esters of hydroxy fatty acids (FAHFAs), a group of bioactive lipids, have emerged as promising agents to treat associated metabolic diseases. This study utilizes one type of FAHFA, oleic acid ester of 9-hydroxystearic acid (9-OAHSA), to treat PA-induced lipoapoptosis in an in vitro MAFLD model using rat hepatocytes and a high-fat high-cholesterol high-fructose (HFHCHFruc) diet in Syrian hamsters. The results indicate that 9-OAHSA rescues hepatocytes from PA-induced apoptosis and attenuates lipoapoptosis and dyslipidemia in Syrian hamsters. Additionally, 9-OAHSA decreases the generation of mitochondrial reactive oxygen species (mito-ROS) and stabilizes the mitochondrial membrane potential in hepatocytes. The study also demonstrates that the effect of 9-OAHSA on mito-ROS generation is at least partially mediated by PKC-δ signaling. These findings suggest that 9-OAHSA shows promise as a therapy for MAFLD.

RESUMO

Mitochondrial dysfunction has been linked to many diseases, including organ degeneration and cancer. Wharton's jelly-derived mesenchymal stem cells provide a valuable source for stem cell-based therapy and represent an emerging therapeutic approach for tissue regeneration. This study focused on screening the senomorphic properties of Ohwia caudata aqueous extract as an emerging strategy for preventing or treating mitochondrial dysfunction in stem cells. Wharton's jelly-derived mesenchymal stem cells were incubated with 0.1 µM doxorubicin, for 24 h to induce mitochondrial dysfunction. Next, the cells were treated with a series concentration of Ohwia caudata aqueous extract (25, 50, 100, and 200 µg/mL) for another 24 h. In addition, an untreated control group and a doxorubicin-induced mitochondrial dysfunction positive control group were maintained under the same conditions. Our data showed that Ohwia caudata aqueous extract markedly suppressed doxorubicin-induced mitochondrial dysfunction by increasing Tid1 and Tom20 expression, decreased reactive oxygen species production, and maintained mitochondrial membrane potential to promote mitochondrial stability. Ohwia caudata aqueous extract retained the stemness of Wharton's jelly-derived mesenchymal stem cells and reduced the apoptotic rate. These results indicate that Ohwia caudata aqueous extract protects Wharton's jelly-derived mesenchymal stem cells against doxorubicin-induced mitochondrial dysfunction and can potentially prevent mitochondrial dysfunction in other cells. This study provides new directions for the medical application of Ohwia caudata.

RESUMO

Fibroblast-like synoviocytes accumulation, proliferation and activation, and the subsequent inflammatory mediators production play a key role in the progression of rheumatoid arthritis (RA). It is well established that Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling triggers inflammation, and induces cytokine levels in RA. Ohwia caudata have long been used against many disorders. However, in RA, the effects of O. caudata have not been elucidated. In the current study, synoviocytes were used to evaluate the suppressive effects of O. caudate extract (OCE) on the pro-inflammatory cytokines production. In vitro, the underlying mechanisms by which OCE inhibits inflammatory response through regulation of suppressors of cytokine signaling 3 (SOCS3) and JAK2/STAT3 expression in IL-17A-treated HIG-82 synoviocytes were investigated. The results demonstrated that the proliferation of IL-17A-challenged cells were increased in comparison with non-stimulated control cells. The synoviocyte proliferation was decreased significantly of OCE concentrations in dose dependent manner. The p-JAK2, p-STAT3, interleukin (IL)-1ß, and IL-6 were reduced in IL-17A-challenged cells treated with OCE. Furthermore, AZD1480 (a JAK2-specific inhibitor) or WP1066 (a STAT3-specific inhibitor) affected the inflammatory mediators production in IL-17A-challenged synoviocytes, and OCE failed to mitigate the IL-17A-induced inflammatory mediators and SOCS3, acting as a feedback inhibitor of the JAK/STAT3 pathway, in the presence of SOCS3 siRNA, indicating that the beneficial effects of OCE on the regulation of inflammatory response homeostasis were dependent on SOCS3 and the JAK2/STAT3 signaling pathway. Our study also showed that SOCS3 was markedly activated by OCE in RA fibroblast-like synoviocytes, thereby decreasing the JAK/STAT3 pathway, and the IL-1ß, and IL-6 activation. Thus, O. caudate should be further investigated as a candidate anti-inflammatory and anti-arthritic agent.

RESUMO

Ohwia caudata (Thunb.) H. Ohashi (Leguminosae) also called as "Evergreen shrub" and Artemisia argyi H.Lév. and Vaniot (Compositae) also named as "Chinese mugwort" those two-leaf extracts frequently used as herbal medicine, especially in south east Asia and eastern Asia. Anthracyclines such as doxorubicin (DOX) are commonly used as effective chemotherapeutic drugs in anticancer therapy around the world. However, chemotherapy-induced cardiotoxicity, dilated cardiomyopathy, and congestive heart failure are seen in patients who receive DOX therapy, with the mechanisms underlying DOX-induced cardiac toxicity remaining unclear. Mitochondrial dysfunction, oxidative stress, inflammatory response, and cardiomyocytes have been shown to play crucial roles in DOX-induced cardiotoxicity. Isoliquiritigenin (ISL, 10 mg/kg) is a bioactive flavonoid compound with protective effects against inflammation, neurodegeneration, cancer, and diabetes. Here, in this study, our aim is to find out the Artemisia argyi (AA) and Ohwia caudata (OC) leaf extract combination with Isoliquiritigenin in potentiating and complementing effect against chemo drug side effect to ameliorate cardiac damage and improve the cardiac function. In this study, we showed that a combination of low (AA 300 mg/kg; OC 100 mg/kg) and high-dose(AA 600 mg/kg; OC 300 mg/kg) AA and OC water extract with ISL activated the cell survival-related AKT/PI3K signaling pathway in DOX-treated cardiac tissue leading to the upregulation of the antioxidant markers SOD, HO-1, and Keap-1 and regulated mitochondrial dysfunction through the Nrf2 signaling pathway. Moreover, the water extract of AA and OC with ISL inhibited the inflammatory response genes IL-6 and IL-1ß, possibly through the NFκB/AKT/PI3K/p38α/NRLP3 signaling pathways. The water extract of AA and OC with ISL could be a potential herbal drug treatment for cardiac hypertrophy, inflammatory disease, and apoptosis, which can lead to sudden heart failure.

RESUMO

Tortoiseshell and deer antler gelatin has been used to treat bone diseases in Chinese society. A pepsin-digested gelatin peptide with osteoblast-proliferation-stimulating properties was identified via LC-MS/MS. The resulting pentapeptide, TSKYR, was presumably subjected to further degradation into TSKY, TSK, and YR fragments in the small intestine. The above four peptides were chemically synthesized. Treatment of tripeptide TSK can lead to a significant 30- and 50-fold increase in the mineralized nodule area and density in osteoblast cells and a 47.5% increase in the number of chondrocyte cells. The calcium content in tortoiseshell was relatively higher than in human soft tissue. The synergistic effects of calcium ions and the peptides were observed for changes in osteoblast proliferation and differentiation. Moreover, these peptides can enhance the expression of RUNX2, OCN, FGFR2, and FRFR3 genes in osteoblasts, and aggrecan and collagen type II in chondrocyte (patent pending).

RESUMO

Intramedullary spinal glioblastoma multiforme (GBM) tends to recur within 11 months of surgical resection, even after adjuvant chemoradiation therapy. Treatment options for recurrent spinal GBM are often limited. (Z)-n-butylidenephthalide [(Z)-BP] is a natural compound that induces apoptosis, antiproliferation, anti-invasion and antistemness effects in GBM cells. The Cerebraca wafer consists of (Z)-BP within a biodegradable wafer that can be implanted in the parenchyma of the central nervous system to treat high-grade glioma. We present a 44-year-old woman with a recurrent spinal GBM who underwent microscopic surgical tumor excision under fluorescein sodium guidance and intraoperative neurophysiologic monitoring. Four Cerebraca wafers were implanted into the cord and intradural space during the operation. MRI revealed that both tumor volume and spinal cord edema had decreased 4 days after surgery; both had substantially decreased 16 months after surgery. Neurologic functions and quality of life were improved after salvage therapy. No adverse events were reported. Cerebraca wafer implantation during surgical re-excision of spinal GBM may be a novel therapeutic approach for reduction of the tumor size and subsequent spinal cord edema with no toxicity to the spinal cord.

RESUMO

BACKGROUND: The usage of machine vision technologies for image-based analysis and inspection is increasing. With the advent of the ability to process high-dimension data instantly, the possibilities of machine vision multiply exponentially. Robots now use this technology to assist in surgery. OBJECTIVE: The aim of this study is to explore the efficacy of Surgical Navigation Robot NaoTrac (Brain Navi Biotechnology Co., Ltd.), which utilizes machine vision-inspired technology for patient registration and stereotactic external ventricular drainage (EVD) by the robotic arm. METHODS: Preoperative and postoperative computed tomography (CT) scans were acquired for each case. The surgeons planned the targets and trajectories with the preoperative CT images. The postoperative CT images were utilized in the accuracy measurements. RESULTS: All 14 cases had cerebrospinal fluid drained through the catheter. The NaoTrac placed the catheter into the frontal horn in one attempt in 13 cases and was able to drain CSF in 12 cases. Not a single case had any bleeding or intraoperative complications. The average time spent on the patient registration was 142.8 s. The mean target deviation was 1.68 mm, and the mean angular deviation was 1.99°, all within the accepted tolerance for minimal tissue damage. CONCLUSION: The results of this report demonstrate that machine vision-inspired patient registration is feasible and fast. NaoTrac has demonstrated its accuracy and safety in performing frameless catheter placement in 13 clinical cases. Other stereotactic neurosurgical operations such as stereotactic biopsy, depth electrode placement, deep brain stimulation electrode positioning, and neuroendoscopy may also be benefited from the assistance of NaoTrac.

RESUMO

Rheumatoid arthritis (RA) is an autoimmune and chronic inflammatory disease that results in joint destruction and disability in the adult population. RA is characterized by the accumulation and proliferation of fibroblast-like synoviocytes. Many pro-inflammatory mediators are associated with RA, such as interleukin (IL)-1ß, IL-6, IL-17, cyclooxygenase-2 (COX-2), and nuclear factor kappa B (NF-κB). Furthermore, IL-17 upregulates the production of other pro-inflammatory mediators, including IL-1ß and IL-6, and promotes the recruitment of neutrophils in RA. Artemisia argyi, a traditional Chinese herbal medicine, is used for the treatment of diseases associated with inflammation and microbial infections. In this study, synoviocytes (HIG-82) were treated with varying doses of A. argyi extract (AAE) following IL-17A stimulation. Proliferation of the IL-17A-stimulated cells was increased compared to that of the non-stimulated control cells. However, cell proliferation decreased significantly in a dose-dependent manner following AAE treatment. Treatment of IL-17A-stimulated cells with AAE resulted in decreased levels of phosphorylated (p)-NF-κB, p-IκB-α, and COX-2. Enzyme-linked immunosorbent assay results showed that IL-1ß and IL-6 levels were increased in the IL-17A-stimulated group but decreased in the AAE treatment group. Additionally, we found that AAE facilitated nuclear factor erythroid 2-related factor 2 (Nrf2) expression and promoted its nuclear translocation, thereby inducing the expression of heme oxygenase-1. Moreover, AAE did not attenuate IL-17A-induced inflammatory mediator production in the presence of ML385, an Nrf2-specific inhibitor. These results suggest that the downregulation of expression of pro-inflammatory cytokines and the transcription factor NF-κB by AAE may be a potential therapeutic strategy for reducing inflammation associated with RA.

RESUMO

Human pluripotent stem cell (hPSC)-derived motor neurons (MNs) act as models for motor neuron diseases (MNDs), such as amyotrophic lateral sclerosis (ALS) or spinal muscular atrophy. However, the MN differentiation efficiency and viability following cryopreservation require further development for application in large-scale studies and drug screening. Here, we developed a robust protocol to convert hPSCs into MN cryopreservation stocks (hPSCs were converted into >92% motor neural progenitors and >91% MNs). Near-mature MNs were cryopreserved at a high thawing survival rate and 89% MN marker expression on day 32. Moreover, these MNs exhibited classical electrophysiological properties and neuromuscular junction (NMJ) formation ability within only 4−6 days after thawing. To apply this platform as an MND model, MN stocks were generated from SOD1G85R, SOD1G85G isogenic control, and sporadic ALS hPSC lines. The thawed ALS MNs expressed ALS-specific cytopathies, including SOD1 protein aggregation and TDP-43 redistribution. Thus, a stable and robust protocol was developed to generate ready-to-use cryopreserved MNs without further neuronal maturation processes for application in MND mechanistic studies, NMJ model establishment, and large-scale drug screening.

RESUMO

Presenilin-1 (PSEN1) is a crucial subunit within the γ-secretase complex and regulates ß-amyloid (Aß) production. Accumulated evidence indicates that n-butylidenephthalide (BP) acts effectively to reduce Aß levels in neuronal cells that are derived from trisomy 21 (Ts21) induced pluripotent stem cells (iPSCs). However, the mechanism underlying this effect remains unclear. This article aims to investigate the possible mechanisms through which BP ameliorates the development of Alzheimer's disease (AD) and verify the effectiveness of BP through animal experiments. Results from RNA microarray analysis showed that BP treatment in Ts21 iPSC-derived neuronal cells reduced long noncoding RNA (lncRNA) CYP3A43-2 levels and increased microRNA (miR)-29b-2-5p levels. Bioinformatics tool prediction analysis, biotin-labeled miR-29b-2-5p pull-down assay, and dual-luciferase reporter assay confirmed a direct negative regulatory effect for miRNA29b-2-5p on lnc-RNA-CYP3A43-2 and PSEN1. Moreover, BP administration improved short-term memory and significantly reduced Aß accumulation in the hippocampus and cortex of 3xTg-AD mice but failed in miR-29b-2-5p mutant mice generated by CRISP/Cas9 technology. In addition, analysis of brain samples from patients with AD showed a decrease in microRNA-29b-2-5p expression in the frontal cortex region. Our results provide evidence that the LncCYP3A43-2/miR29-2-5p/PSEN1 network might be involved in the molecular mechanisms underlying BP-induced Aß reduction.

RESUMO

BACKGROUND: This study aimed to evaluate fetal adverse outcomes of laparoscopy and laparotomy in pregnant women to determine the safety of these surgical approaches. METHODS: This was a retrospective nationwide case-control study of women who became pregnant for the first time between 2000 and 2012 in Taiwan. The case (with adverse fetal outcomes) and control groups comprised 208,604 and 417,124 participants, respectively. Participants who underwent appendectomy, cholecystectomy, ovarian cystectomy, or myomectomy were treated with either laparoscopy or laparotomy. A conditional logistic regression model was used to calculate the odds ratios (ORs) for adverse fetal outcomes. RESULTS: The laparotomy and laparoscopy groups comprised 632 and 536 patients, respectively. Women who underwent laparoscopy had a significantly higher risk of adverse fetal outcomes (adjusted OR [AOR] = 2.33; 95% CI 1.66-2.99) than those who underwent laparotomy. Adverse fetal outcomes were found to be significantly associated with laparoscopy among women aged 20-39 years (AOR = 2.30; 95% CI 1.70-3.31). Regarding surgical indication, unlike laparotomy, laparoscopic cholecystectomy and appendectomy were not associated with adverse fetal outcomes. However, laparoscopic myomectomy and ovarian surgeries were associated with a higher incidence of adverse fetal outcomes than the laparotomy group (AOR = 2.29 [95% CI 1.57-3.35, p < 0.0001] and AOR = 2.52 [95% CI 1.58-4.04, p = 0.0001], respectively). CONCLUSIONS: Pregnant women who underwent laparoscopic surgery experienced significantly more adverse fetal outcomes than those who underwent laparotomy. Therefore, pregnant women undergoing either laparotomy or laparoscopy should be informed of the risk of adverse fetal outcomes.

RESUMO

Spinocerebellar ataxia type 3 (SCA3), a hereditary and lethal neurodegenerative disease, is attributed to the abnormal accumulation of undegradable polyglutamine (polyQ), which is encoded by mutated ataxin-3 gene (ATXN3). The toxic fragments processed from mutant ATXN3 can induce neuronal death, leading to the muscular incoordination of the human body. Some treatment strategies of SCA3 are preferentially focused on depleting the abnormal aggregates, which led to the discovery of small molecule n-butylidenephthalide (n-BP). n-BP-promoted autophagy protected the loss of Purkinje cell in the cerebellum that regulates the network associated with motor functions. We report that the n-BP treatment may be effective in treating SCA3 disease. n-BP treatment led to the depletion of mutant ATXN3 with the expanded polyQ chain and the toxic fragments resulting in increased metabolic activity and alleviated atrophy of SCA3 murine cerebellum. Furthermore, n-BP treated animal and HEK-293GFP-ATXN3-84Q cell models could consistently show the depletion of aggregates through mTOR inhibition. With its unique mechanism, the two autophagic inhibitors Bafilomycin A1 and wortmannin could halt the n-BP-induced elimination of aggregates. Collectively, n-BP shows promising results for the treatment of SCA3.

RESUMO

Parkinson's disease (PD) is a degenerative disease that can cause motor, cognitive, and behavioral disorders. The treatment strategies being developed are based on the typical pathologic features of PD, including the death of dopaminergic (DA) neurons in the substantia nigra of the midbrain and the accumulation of α-synuclein in neurons. Peiminine (PMN) is an extract of Fritillaria thunbergii Miq that has antioxidant and anti-neuroinflammatory effects. We used Caenorhabditis elegans and SH-SY5Y cell models of PD to evaluate the neuroprotective potential of PMN and address its corresponding mechanism of action. We found that pretreatment with PMN reduced reactive oxygen species production and DA neuron degeneration caused by exposure to 6-hydroxydopamine (6-OHDA), and therefore significantly improved the DA-mediated food-sensing behavior of 6-OHDA-exposed worms and prolonged their lifespan. PMN also diminished the accumulation of α-synuclein in transgenic worms and transfected cells. In our study of the mechanism of action, we found that PMN lessened ARTS-mediated degradation of X-linked inhibitor of apoptosis (XIAP) by enhancing the expression of PINK1/parkin. This led to reduced 6-OHDA-induced apoptosis, enhanced activity of the ubiquitin-proteasome system, and increased autophagy, which diminished the accumulation of α-synuclein. The use of small interfering RNA to down-regulate parkin reversed the benefits of PMN in the PD models. Our findings suggest PMN as a candidate compound worthy of further evaluation for the treatment of PD.

RESUMO

Functional decline of stem cell transplantation in ageing hosts is well documented. The mechanism for this is poorly understood, although it is known that advancing age does not provide an optimal milieu for exogenous stem cells to survive, engraft and differentiate. We showed that n-butylidenephthalide improved human adipose-derived stem cell (hADSC) engraftment via attenuating the production of reactive oxygen species (ROS). It remained unclear whether pre-treated hosts with n-butylidenephthalide can rejuvenate the ageing heart and improve hADSC engraftment by regulating the ROS/NLRP3 inflammasome-mediated cardiac fibrosis after myocardial infarction. One hour after coronary ligation, hADSCs were transplanted into the hearts of young and ageing Wistar rats that were pre-treated with or without n-butylidenephthalide for 3 days. At day 3 after infarction, myocardial infarction was associated with an increase in ROS levels and NLRP3 inflammasome activity with age. hADSC transplant effectively provided a significant decrease in ROS levels, NLRP3 inflammasome activity, IL-1ß levels and cardiac fibrosis in either young or old infarcted rats. However, the beneficial effects of hADSCs were greater in young compared with old rats in terms of NLRP3 inflammasome activity. The infarcted ageing rats pre-conditioned by n-butylidenephthalide improved engraftment and differentiation of hADSCs and additionally attenuated cardiac fibrosis compared with hADSCs alone. The anti-inflammation effects of n-butylidenephthalide were reversed by SIN-1. In conclusions, the increased NLRP3 inflammasome activity plays the pathogenesis of ageing-related functional hADSC decline in the ageing hosts. n-butylidenephthalide-pre-treated ageing hosts reversibly ameliorate the harsh microenvironments, improve stem cell engraftment and attenuate cardiac fibrosis after myocardial infarction.

RESUMO

The discovery of brown fat in adult humans has led to increased research of the thermogenic function of this tissue in various metabolic diseases. In addition, high levels of brown fat have been correlated with lower body mass index values. Therefore, increasing brown fat mass and/or activity through methods such as the browning of white fat is considered a promising strategy to prevent and treat obesity-associated diseases. Cell-based approaches using mesenchymal stromal cells and brown adipose tissue (BAT) have been utilized to directly increase BAT mass/activity through cell and tissue implantation into animals. In addition, recent studies evaluating the transplantation of human embryonic stem cells and induced pluripotent stem (iPS) cells have shown promising results in terms of positive metabolic function. In this comprehensive review, we provide a summary of the research over the past 10 years with regard to stem cell therapy and brown fat tissue transplantation for the effective treatment of metabolic syndrome. Recent advancements in stem cell methods have allowed for the production of brown adipocytes from human iPS cells, which represent an unlimited source of cellular material with which to study adipocyte development. In addition, this process is expected to be used to further explore drug- and cell-based therapies to treat obesity-related metabolic complications.

RESUMO

We aim to evaluate breast cancer risk relating to PPIs usage in women with peptic ulcer. From 2000 to 2013, incidence rates of breast cancer were compared between the two cohorts (with or without PPIs). Each study cohort consisted of 4838 women. The incidence density rate of breast cancer in the PPI cohort was 0.29 that in the comparison cohort (10.0 vs 31.6 per 10 000 person-years), with an adjusted HR (hazard ratio) of 0.32 (95% CI = 0.20-0.49) for the PPI cohort. In conclusion, the medication of PPIs is associated with reduced breast cancer risk for women with gastric ulcer.

RESUMO

BACKGROUND: Clinical guidelines for specific conditions fragment care provision for elders. The International Consortium for Health Outcomes Measurement (ICHOM) has developed a global standard set of outcome measures for comprehensive assessment of older persons. The goal of this study was to report value-based health metrics in Taiwan using this ICHOM toolset. METHODS: The cross-sectional study of baseline data excerpted from a prospective longitudinal cohort, which recruited people ≥65 years old with ≥3 chronic medical conditions between July and December 2018. All participants received measurements of physical performance, anthropometric characteristics, health-related behaviors, Charlson Comorbidity Index, and Montreal Cognitive Assessment. The ICHOM toolset comprises three tiers: 1 includes frailty and having chosen a preferred place of death; 2 includes polypharmacy, falls, and participation in decision-making; and 3 includes loneliness, activities of daily living, pain, depression, and walking speed. These items were converted into a 0-10 point value-based healthcare score, with high value-based health status defined as ≥8/10 points. RESULTS: Frequencies of individual ICHOM indicators were: frail 11.7%, chose preferred place of death 14.4%, polypharmacy 31.5%, fell 17.1%, participated in decision-making 81.6%, loneliness 26.8%, limited activities of daily living 22.4%, pain 10.4%, depressed mood 13.0%, and slowness 38.5%. People with high disease burden (OR 0.40, 95% CI 0.21-0.76, p = 0.005) or cognitive impairment (OR 0.49, 95%CI 0.27-0.87, p = 0.014) were less likely to have high value-based healthcare status. CONCLUSIONS: The ICHOM Standard Set Older Person health outcome measures provide an opportunity to shift from a disease-centric medical paradigm to whole person-focused goals. This study identified advanced age, chronic disease burden and cognitive impairment as important barriers to achieving high value-based healthcare status.

RESUMO

Spinocerebellar ataxia type 3/Machado-Joseph disease (SCA3/MJD) is a progressive motor disease with no broadly effective treatment. However, most current therapies are based on symptoms rather than the underlying disease mechanisms. In this review, we describe potential therapeutic strategies based on known pathological biomarkers and related pathogenic processes. The three major conclusions from the current studies are summarized as follows: (i) for the drugs currently being tested in clinical trials; a weak connection was observed between drugs and SCA3/MJD biomarkers. The only two exceptions are the drugs suppressing glutamate-induced calcium influx and chemical chaperon. (ii) For most of the drugs that have been tested in animal studies, there is a direct association with pathological biomarkers. We further found that many drugs are associated with inducing autophagy, which is supported by the evidence of deficient autophagy biomarkers in SCA3/MJD, and that there may be more promising therapeutics. (iii) Some reported biomarkers lack relatively targeted drugs. Low glucose utilization, altered amino acid metabolism, and deficient insulin signaling are all implicated in SCA3/MJD, but there have been few studies on treatment strategies targeting these abnormalities. Therapeutic strategies targeting multiple pathological SCA3/MJD biomarkers may effectively block disease progression and preserve neurological function.
