Objectives: To compare the therapeutic efficacy, adverse events (AEs), and patient preference in elderly patients with overactive bladder (OAB) receiving different combinations of mirabegron and solifenacin.
Materials and methods: Elderly OAB patients received mirabegron 25 mg (M25) daily for 1 month (1M) followed by randomization to receive M25 (Group 1), mirabegron 50 mg (M50, Group 2), solifenacin 5 mg (S5, group 3); or M25 plus S5 (Group 4) for further 2 months. Efficacy and AEs were evaluated. At the end of 3M, patients' preferred option for future treatment was investigated.
Results: A total of 168 patients were enrolled, and 100 completed 3-month treatment. At 1M, all parameters improved significantly except postvoid residual (PVR), 23 (13.7%) patients had no symptom, 16 (9.5%) had no improvement, and 10 (6.0%) withdrew from the trial. Compared parameters at 3M with 1M revealed that quality of life, Patient's Perception of Bladder Condition scores, and voided volume improved significantly in group 1; the OAB Symptom Score (OABSS) increased in group 2; mean PVR and Global Response Assessment (GRA) deteriorated in group 3; and the OABSS and GRA improved in group 4. At 3M, the AEs prevalence increased significantly in group 3. Only 38.1% in group 4 preferred long-term usage of combination therapy.
Conclusion: M25 daily is effective and safe in treating elderly OAB patients. Dose escalation to 50 mg or shifting to S5 does not increase the therapeutic efficacy. Combining M25 with S5 provides better treatment efficacy but is associated with lower patient compliance than M25 alone.
Objectives: In this double-blind, randomized clinical trial, the effectiveness of buprenorphine (BUPRE) in the reduction of anxiety symptoms among the methamphetamine (MA) dependents was evaluated.
Materials and methods: The 60 MA-dependent patients were randomly assigned to three groups (0.1 mg, 1 mg, and 8 mg of BUPRE), The Hamilton Anxiety Rating Scale was administrated to assess the anxiety symptoms daily at baseline and second to the 5th day after intervention. The inclusion criteria were the MA dependence, age of over 18 years, and absence of any chronic physical illnesses; exclusion criteria were the presence of other drug dependence in combination with MA. The mixed-design analysis of variance was performed for data analysis.
Results: A significant main effect of time (F = 51.456, P < 0.001) and group (F = 4.572, P = 0.014) and group-by-time interaction (F = 8.475, P < 0.001) were detected.
Conclusions: This finding supports the efficacy of BUPRE to decrease anxiety. High doses of the drug (1 and 8 mg) were more effective than 0.1 mg. Here was not a significant difference between anxiety score when patients received 1 mg of BUPRE instead of 8 mg.
Objectives: This study aimed to assess the impact of small for gestational age (SGA) on the development of Taiwanese preschool children using the Chinese Child Developmental Inventory (CCDI).
Materials and methods: A total of 982 children were enrolled in this study between June 2011 and December 2015. The samples were divided into two groups: SGA (n = 116, mean age = 2.98) and non-SGA (n = 866, mean age = 3.33) groups. The development scores were based on the CCDI, which consist of eight dimensions of development between the two groups. The linear regression analysis was adopted to examine the relationship of SGA with child development.
Results: On average, the children in the SGA group scored less in all eight subitems of the CCDI than those in the non-SGA group. However, regression analysis revealed that there was no significant difference in both performance and delay frequency in the CCDI between the two groups.
Conclusion: SGA children had similar developmental scores in CCDI as non-SGA children for preschool age in Taiwan.
Objectives: Obstructive sleep apnea (OSA) is a sleep disorder which results in daytime sleepiness and impaired memory function. The aim of this study was to investigate the effect of continuous positive airway pressure (CPAP) on daytime sleepiness and memory function in OSA patients. We also investigated whether CPAP compliance impacted the effect of this treatment.
Materials and methods: The nonrandomized, nonblinded clinical trial enrolled 66 patients with moderate-to-severe OSA subjects. All subjects completed a polysomnographic study, daytime sleepiness questionnaires (the Epworth Sleepiness Scale and the Pittsburgh Sleep Quality Index), and four memory function tests (working memory; processing speed [PS]; logical memory [LM]; face memory [FM]).
Results: Before CPAP treatment, no significant differences (P < 0.05) were noted in the demographic data, daytime sleepiness, or memory function between two groups (with/without CPAP). However, OSA patients treated with CPAP for 2 months showed significant improvements in daytime sleepiness, PS, mostly of LM, and FM comparing to 2 months ago. As compared to those who did not receive CPAP treatment, CPAP can improve only parts of LM (delayed LM [DLM] and LM percentage [LMP]). In addition, compared to control group, a significant improvement of daytime sleepiness and LM (LM learning, DLM, and LMP) in good compliance with CPAP treatment group and of DLM and LMP in the low compliance with CPAP treatment group was found.
Conclusion: CPAP treatment for 2 months could improve some of LM in OSA patients, especially in patients exhibiting good CPAP compliance.
Intracerebral hemorrhage (ICH) is the most lethal type of cerebral stroke without effective therapy. Although clinical trials with various surgeries have been conducted, none have improved clinical outcomes compared to the current medical management for ICH. Several ICH animal models, including autologous blood injection, collagenase injection, thrombin injection, and microballoon inflation methods, have been developed to elucidate the underlying mechanisms of ICH-induced brain injury. These models could also be used for discovering new therapy for ICH preclinically. We summarize the existing ICH animal models and the evaluation parameters used to measure the disease outcomes. We conclude that these models, resembling the different aspects of ICH pathogenesis, have their advantages and disadvantages. None of the current models closely represent the severity of ICH seen in clinical settings. More appropriate models are needed to streamline ICH's clinical outcomes and be used for validating newly developed treatment protocols.
Cerebrospinal fluid (CSF) and its drainage are crucial in clearing metabolic waste and maintaining the microenvironment of the central nervous system for proper functioning. Normal-pressure hydrocephalus (NPH) is a serious neurological disorder of the elderly with obstruction of CSF flow outside the cerebral ventricles, causing ventriculomegaly. The stasis of CSF in NPH compromises brain functioning. Although treatable, often with shunt implantation for drainage, the outcome depends highly on early diagnosis, which, however, is challenging. The initial symptoms of NPH are hard to be aware of and the complete symptoms overlap with those of other neurological diseases. Ventriculomegaly is not specific to NPH as well. The lack of knowledge on the initial stages in its development and throughout its progression further deters early diagnosis. Thus, we are in dire need for an appropriate animal model for researches into a more thorough understanding of its development and pathophysiology so that we can enhance the diagnosis and therapeutic strategies to improve the prognosis of NPH following treatment. With this, we review the few currently available experimental rodent NPH models for these animals are smaller in sizes, easier in maintenance, and having a rapid life cycle. Among these, a parietal convexity subarachnoid space kaolin injection adult rat model appears promising as it shows a slow onset of ventriculomegaly in association with cognitive and motor disabilities resembling the elderly NPH in humans.
Mesenchymal stem cells (MSCs) were applied to the therapy for degenerative diseases, immune, and inflammation. In tumor microenvironments (TME), different sources of MSCs showed that tumor-promoting and -inhibiting effects were mediated by different signaling pathways. Cancer-associated MSCs (CaMSCs) could be recruited from bone marrow or local tissues and mainly showed tumor-promoting and immunosuppressive effects. The transformed CaMSCs preserve the characteristics of stem cells, but the properties of regulating TME are different. Hence, we specifically focus on CaMSCs and discuss the detailed mechanisms of regulating the development of cancer cells and immune cells. CaMSCs could be a potential therapeutic target in various types of cancer. However, the detailed mechanisms of CaMSCs in the TME are relatively less known and need further study.
