Prognostic impact of angiotensin-converting enzyme inhibitors and angiotensin receptors blockers in esophageal or gastric cancer patients with hypertension - a real-world study.

BACKGROUND: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are used in treating cardiovascular diseases. Previous studies indicated that ACEIs/ARBs may benefit cancer patients by inhibiting tumor angiogenesis and proliferation. The effect of ACEIs/ARBs on cancer survival in esophageal and gastric cancer is still unclear. This study is to investigate the association between ACEIs/ARBs usage and esophageal and gastric cancer prognosis. METHODS: This retrospective cohort study identified esophageal and gastric cancer patients during 2008-2016 from the Taiwan Cancer Registry, and obtained medication usage and follow-up information from the National Health Insurance Research Database and Death Registry. Analysis groups were defined as ACEIs/ARBs user or non-user based on the usage of ACEIs/ARBs within the 6 months after cancer diagnosis. The stabilized inverse probability of treatment weighting using propensity scores was applied to balance covariates between study groups. We also used Kaplan-Meier estimates and Cox regression to compare survival outcome and estimate hazard ratios (HRs). RESULTS: We identified 14,463 and 21,483 newly-diagnosed esophageal and gastric cancer patients during 2008-2016. ACEIs/ARBs users were associated with lower risk of cancer-specific mortality, although only significantly in gastric cancer (gastric: adjusted HR = 0.87, 95% CI = 0.78-0.97; esophageal: adjusted HR =0.88, 95% CI = 0.76-1.02). A better survival outcome was observed among patients who received higher cumulative defined daily dose of ACEIs/ARBs. CONCLUSIONS: We found that using ACEIs/ARBs after cancer diagnosis were associated with lower risk of mortality. Our results add to the knowledge of the benefit of ACEIs/ARBs against mortality in individuals with esophageal/gastric cancer patients with hypertension.

Cardiovascular events in patients with chronic myeloid leukaemia treated with tyrosine kinase inhibitors in Taiwan: a nationwide population-based study.

AIMS: New-generation breakpoint cluster region-Abelson tyrosine kinase inhibitors (TKIs) have a higher incidence of cardiovascular events than imatinib in patients with chronic myeloid leukaemia (CML). However, this knowledge is insufficiently proven. Hence, this study aimed to explore the association between cardiovascular events and TKIs in patients with CML. METHODS AND RESULTS: This retrospective population-based cohort study enrolled first-time users of imatinib, dasatinib, and nilotinib between 1 January 2007 and 31 December 2016. Arterial thromboembolic events (ATEs) were the primary outcome, while other cardiovascular-related events were the secondary outcomes. The event rates were estimated using Kaplan-Meier estimates, and the hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox regression. Additionally, the competing risk was adjusted using the Fine and Gray competing risk model. We included 1207 patients. Nilotinib had a significantly higher ATE risk (subdistribution HR = 4.92, 95% CI = 1.68-14.36) than imatinib. Conversely, no difference was found for other cardiovascular-related events. Risks of ATE and other cardiovascular-related events were similar between dasatinib and imatinib and between nilotinib and dasatinib. The risk of ATE hospitalization consistently increased throughout the main analyses and sensitivity analyses. CONCLUSION: Nilotinib-treated patients had a significantly higher risk of developing ATE than imatinib-treated patients. However, the risks of ATE and other cardiovascular-related events were not significantly different between dasatinib and imatinib.

Effects of kinesio taping on hemiplegic hand in patients with upper limb post-stroke spasticity: a randomized controlled pilot study.

BACKGROUND: Post-stroke spasticity is a common complication in patients with stroke and a key contributor to impaired hand function after stroke. AIM: The purpose of this study was to investigate the effects of kinesio taping on managing spasticity of upper extremity and motor performance in patients with subacute stroke. DESIGN: A randomized controlled pilot study. SETTING: A hospital center. POPULATION: Participants with stroke within six months. METHODS: Thirty-one participants were enrolled. Patients were randomly allocated into kinesio taping (KT) group or control group. In KT group, Kinesio Tape was applied as an add-on treatment over the dorsal side of the affected hand during the intervention. Both groups received regular rehabilitation 5 days a week for 3 weeks. The primary outcome was muscle spasticity measured by modified Ashworth Scale (MAS). Secondary outcomes were functional performances of affected limb measured by using Fugl-Meyer assessment for upper extremity (FMA-UE), Brunnstrom stage, and the Simple Test for Evaluating Hand Function (STEF). Measures were taken before intervention, right after intervention (the third week) and two weeks later (the fifth week). RESULTS: Within-group comparisons yielded significant differences in FMA-UE and Brunnstrom stages at the third and fifth week in the control group (P=0.003-0.019). In the KT group, significant differences were noted in FMA-UE, Brunnstrom stage, and MAS at the third and fifth week (P=0.001-0.035), and in the proximal part of FMA-UE between the third and fifth week (P=0.005). Between-group comparisons showed a significant difference in the distal part of FMA-UE at the fifth week (P=0.037). CONCLUSIONS: Kinesio taping could provide some benefits in reducing spasticity and in improving motor performance on the affected hand in patients with subacute stroke. CLINICAL REHABILITATION IMPACT: Kinesio taping could be a choice for clinical practitioners to use for effectively managing post-stroke spasticity.

A technique for creating critical-size defects in the metatarsus of sheep for use in investigation of healing of long-bone defects.

OBJECTIVE: To develop a technique for use in investigation of healing of long-bone defects by creation of a critical-size defect in the left metarsal III and IV bone (metatarsus) of sheep. ANIMALS: 18 healthy adult sheep. PROCEDURE: Sheep were allocated to 4 groups (3, 3, 5, and 7 sheep in groups 1 to 4, respectively). An ostectomy with various segmental length-to-diaphyseal diameter ratios (0.5, 1.0, 2.0, and 2.0 for groups 1 to 4, respectively) was performed on the left metatarsus of each sheep. The defect was left empty in sheep of groups 1, 2, and 3, whereas the defect was filled with a massive corticocancellous bone autograft in sheep of group 4. RESULTS: All sheep tolerated the surgical procedure well and were able to use the affected limb the day after surgery. Radiographic and histologic examinations conducted 16 weeks after surgery revealed nonunion in all sheep of groups 1, 2, and 3, whereas consistent bone healing with abundant bone formation was observed in all sheep of group 4. CONCLUSIONS AND CLINICAL RELEVANCE: Analysis of these findings suggests that the sheep metatarsal model is a critical-size defect model with low morbidity. It should allow the assessment of new technologies for bone regeneration in conditions closely mimicking the clinical setting. IMPACT FOR HUMAN MEDICINE: Use of this technique in sheep should be of benefit for the preclinical study of osteoconductive, osteoinductive, or osteogenic biomaterials for use in humans.
