Mino induced autophagy by eliciting endoplasmic reticulum stress response and switched cell death from autophagy to apoptosis when autophagy was blocked. These results coupled with clinical availability and a safe track record make Mino a promising agent for the treatment of malignant gliomas.
Introduction. Although palliative chemotherapy during end‐of‐life care is used for relief of symptoms in patients with metastatic cancer, chemotherapy may lead to more aggressive end‐of‐life care and less use of hospice service. This is a population‐based study of the association between palliative chemotherapy and aggressiveness of end‐of‐life care. Patients and Methods. Using the National Health Insurance Research Database of Taiwan, we identified 49,920 patients with metastatic cancer who underwent palliative chemotherapy from January 1, 2009, to December 31, 2011. Patients who received chemotherapy 2–6 months before death were included. Aggressiveness of end‐of‐life care was examined by previously reported indicators. Cardiopulmonary resuscitation and endotracheal tube intubation were included as indicators of aggressive end‐of‐life care. The association between palliative chemotherapy and hospice care was studied. Results. Palliative chemotherapy was associated with more aggressive treatment. After adjustment for patient age, sex, Charlson Comorbidity Index score, cancer group, primary physician's specialty, postdiagnosis survival, hospital characteristics, hospital caseload, urbanization, and geographic regions, more than one emergency room visit (p < .001), more than one intensive care unit admission (p < .001), and endotracheal intubation (p = .02) during end‐of‐life care were significantly more common in patients receiving palliative chemotherapy. Patients who did not receive palliative chemotherapy received more hospice care in the last 6 months of life (p < .001). Conclusion. Although the decision to initiate palliative chemotherapy was made several months before death, this study showed that palliative chemotherapy was associated with more aggressive end‐of‐life care, including more emergency room visits and intensive care unit admissions, and endotracheal intubation. The patients who received palliative chemotherapy received less hospice service toward the end of life. Implications for Practice: Palliative chemotherapy is used for patients with incurable cancer toward the end of life (EOL). Aggressiveness of EOL care and hospice care are related to the quality of life of these patients. This study of data from the Taiwanese National Health Insurance Research Database found that palliative chemotherapy led to more aggressive EOL care and less hospice care. There is a need to provide patients with terminal cancer access to care information that best meets their needs, especially those patients who receive palliative chemotherapy.
Magnesium sulfate and nimesulide are commonly used drugs with reported neuroprotective effects. Their combination as stroke treatment has the potential benefits of decreasing individual drug dosage and fewer adverse effects. This study evaluated their synergistic effects and compared a low-dose combination with individual drug alone and placebo. Sprague-Dawley rats underwent 90 min of focal ischemia with intraluminal suture occlusion of the middle cerebral artery followed by reperfusion. The rats were randomly assigned to receive one of the following treatments: placebo, magnesium sulfate (MgSO₄; 45 mg/kg) intravenously immediately after the induction of middle cerebral artery occlusion, nimesulide (6 mg/kg) intraperitoneally before reperfusion, and combined therapy. Three days after the ischemia-reperfusion insult, therapeutic outcome was assessed by 2,3,5-triphenyltetrazolium chloride staining and a 28-point neurological severity scoring system. Cyclooxygenase-2, prostaglandin E₂, myeloperoxidase, and caspase-3 expression after treatment were evaluated using Western blot analyses and immunohistochemical staining, followed by immunoreactive cell analysis using tissue cytometry. Only the combination treatment group showed a significant decrease in infarction volume (10.93±6.54% versus 26.43±7.08%, p<0.01), and neurological severity score (p<0.05). Low-dose MgSO₄ or nimesulide showed no significant neuroprotection. There was also significant suppression of cyclooxygenase-2, prostaglandin E₂, myeloperoxidase, and caspase-3 expression in the combination treatment group, suggesting that the combination of the two drugs improved the neuroprotective effects of each individual drug. MgSO₄ and nimesulide have synergistic effects on ischemia-reperfusion insults. Their combination helps decrease drug dosage and adverse effects. Combined treatment strategies may help to combat stroke-induced brain damage in the future.
Aims: Taiwan has the highest incidence and prevalence of end-stage renal disease worldwide. Haptoglobin (Hp) has a role in renal protection, and there are known differences in the function of different Hp alleles. We aim to study the association between Hp genotype and chronic kidney disease (CKD) in Taiwan. Methods: We performed one hospital-based, age-matched case-control study of 213 patients with CKD and 213 controls to evaluate the association between Hp polymorphism and CKD. Three major Hp genotypes were determined using polymerase chain reaction and electrophoresis. An unconditional logistic regression model was used to identify the associated risk factors for the development of CKD. Results: The frequency of Hp2-2 genotype and Hp2 allele was significantly higher in the CKD group than in controls (p = 0.032 and 0.024, respectively). After adjustment for covariates, the Hp2-2 genotype (vs. Hp1-1; OR 3.841) remained significantly associated with the development of CKD, together with diabetes (OR 3.131), hypertension (OR 1.748) and dyslipidemia (OR 1.646). Conclusion: This present study shows that Hp2-2 genotype is an independent risk factor for CKD. Determination of the Hp genotype may be of potential value to the prediction of genetic risk for CKD.
