RESUMO

CONTEXT: Numerous studies have shown that gratitude can reduce stress and improve quality of life. OBJECTIVE: Our study aimed to examine the effect of mindful gratitude journaling on suffering, psychological distress and quality of life of patients with advanced cancer. METHODS: We conducted a parallel-group, blinded, randomised controlled trial at the University of Malaya Medical Centre, Malaysia. Ninety-two adult patients with advanced cancer, and an overall suffering score ≥4/10 based on the Suffering Pictogram were recruited and randomly assigned to either a mindful gratitude journaling group (N=49) or a routine journaling group (N=43). RESULTS: After 1 week, there were significant reductions in the overall suffering score from the baseline in both the intervention group (mean difference in overall suffering score=-2.0, 95% CI=-2.7 to -1.4, t=-6.125, p=0.000) and the control group (mean difference in overall suffering score=-1.6, 95% CI=-2.3 to -0.8, t=-4.106, p=0.037). There were also significant improvements in the total Hospital Anxiety and Depression Scale score (mean difference=-3.4, 95% CI=-5.3 to -1.5, t=-3.525, p=0.000) and the total Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being score (mean difference=7.3, 95% CI=1.5 to 13.1, t=2.460, p=0.014) in the intervention group after 7 days, but not in the control group. CONCLUSION: The results provide evidence that 7 days of mindful gratitude journaling could positively affect the state of suffering, psychological distress and quality of life of patients with advanced cancer. TRIAL REGISTRATION NUMBER: The trial was registered with the Australian and New Zealand Clinical Trials Registry (ACTRN1261800172191) and conducted in accordance with the Declaration of Helsinki.

RESUMO

To palliate suffering, understanding the circumstances leading to suffering and its amelioration could be helpful. Our study aimed to explore contributing and relieving factors of suffering in palliative care. Adult palliative care stage III or IV cancer in-patients were recruited from University of Malaya Medical Centre. Participants recorded their overall suffering score from 0 to 10 three times daily, followed by descriptions of their contributing and relieving factors. Factors of suffering were thematically analysed with NVIVO. Descriptive data were analysed with SPSS. 108 patients participated. The most common contributing factor of suffering was health factor (96.3%), followed by healthcare factor (78.7%), psychological factor (63.0%) and community factor (20.4%). The most common relieving factor was health factor (88.9%), followed by psychological factor (78.7%), community factor (75.9%) and healthcare factor (70.4%). Self-reported assessment of suffering offers a rapid approach to detect bothering issues that require immediate attention and further in-depth exploration.

RESUMO

Atherosclerosis is a chronic disease of arteries, which constitutes the pathological basis of a series of cardiovascular diseases. The inflammatory response of vascular endothelial cells mediated by oxidized low density lipoprotein (ox-LDL) is the early behavior and main signal of atherosclerosis. In this study, the damage model of vascular endothelial cells treated with ox-LDL was used to reproduce the damage process of vascular endothelial cells in the process of atherosclerosis. Cell viability was detected by CCK-8. The release levels of reactive oxygen species, nitric oxide, and superoxide dismutase (SOD) were detected by commercial kits. EdU cell proliferation assay was used to detect cell proliferation, real-time fluorescent quantitative PCR and Western blot were used to detect the expression level of related genes. The results showed we successfully constructed a vascular endothelial injury model by incubating vascular endothelial cells with gradient concentrations of ox-LDL. The incubation of safflor yellow A (SYA) partially restored the loss of viability of vascular endothelial cells mediated by ox-LDL, and SYA could promote the proliferation of injured vascular endothelial cells. In addition, SYA may transmit related signals through the AMPK pathway to protect vascular endothelial cells from ox-LDL-mediated damage. All these results provide a further understanding of the occurrence and development of atherosclerosis, provide a theoretical basis for the use of SYA-related drugs in the treatment of cardiovascular diseases, and provide a reference paradigm for studying the pharmacology, toxicology, and mechanism of action of key active substances in TCM.

RESUMO

PURPOSE: To validate a 10-point scoring system for the prediction of successful treatment modality in patients with cesarean scar pregnancy (CSP). PATIENTS AND METHODS: Data were collected from women seen between April 1, 2018, and June 30, 2019, at the Second Affiliated Hospital of Army Medical University of China who were diagnosed with CSP and underwent evacuation, followed by uterine artery embolization (UAE) and successive laparoscopic local resection as salvage treatment if necessary. A score was computed based on clinical and ultrasonographic parameters included in a previously developed scoring system. Treatment indicated by the scoring system was compared with actual treatment received. Receiver operating characteristic (ROC) curves were used to identify cut-off scores for salvage treatment. RESULTS: Of 183 women, 108 were successfully treated by evacuation, 57 required UAE, and 18 eventually underwent laparoscopic surgery. Among 97 women scoring 0-4, 89 (91.8%) were treated by evacuation only. Of 69 women scoring between 5 and 7, 44 (63.8%) needed UAE following evacuation. Of 17 women scoring 8-10, 10 women (58.8%) underwent laparoscopic surgery. A cut-off of 4.145 was obtained by ROC curve for prediction of any salvage treatment; this was comparable to the scale's conventional cut-off of 4. The cut-off score for women requiring laparoscopic surgery was 6.580, which was lower than 8 obtained in the scale's initial validation. CONCLUSION: The overall performance of the 10-point scoring system was moderate for predicting successful treatment modalities of women with CSP, but the scale showed good predictive ability in recognizing women needing only evacuation before recovery.

RESUMO

Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture. The needles were either twirled at Tiaoshen Yizhi acupoints, including Sishencong (EX-HN1), Yintang (EX-HN3), Neiguan (PC6), Taixi (KI3), Fenglong (ST40), and Taichong (LR3), or at related sham acupoints at a depth of approximately 15 mm, an angle of ± 60°, and a rate of approximately 120 times per minute. Acupuncture was conducted for 4 consecutive weeks, five times per week, on weekdays. Resting-state functional magnetic resonance imaging indicated that connections between cognition-related regions such as the insula, dorsolateral prefrontal cortex, hippocampus, thalamus, inferior parietal lobule, and anterior cingulate cortex increased after acupuncture at Tiaoshen Yizhi acupoints. The insula, dorsolateral prefrontal cortex, and hippocampus acted as central brain hubs. Patients in the Tiaoshen Yizhi group exhibited improved cognitive performance after acupuncture. In the sham acupoint acupuncture group, connections between brain regions were dispersed, and we found no differences in cognitive function following the treatment. These results indicate that acupuncture at Tiaoshen Yizhi acupoints can regulate brain networks by increasing connectivity between cognition-related regions, thereby improving cognitive function in patients with mild cognitive impairment.

RESUMO

Most tumors are epithelial-derived, and although disruption of polarity and aberrant cellular junction formation is a poor prognosticator in human cancer, the role of polarity determinants in oncogenesis is poorly understood. Using in vivo selection, we identified a mammalian orthologue of the Drosophila polarity regulator crumbs as a gene whose loss of expression promotes tumor progression. Immortal baby mouse kidney epithelial cells selected in vivo to acquire tumorigenicity displayed dramatic repression of crumbs3 (crb3) expression associated with disruption of tight junction formation, apicobasal polarity, and contact-inhibited growth. Restoration of crb3 expression restored junctions, polarity, and contact inhibition while suppressing migration and metastasis. These findings suggest a role for mammalian polarity determinants in suppressing tumorigenesis that may be analogous to the well-studied polarity tumor suppressor mechanisms in Drosophila.

RESUMO

Defects in apoptosis that evolve during the course of cancer progression not only provide cancer cells with intrinsic survival advantage, but also provide inherent resistance to chemotherapeutic agents. Thus, modulation of apoptosis by targeting components of the apoptotic machinery and its regulators to restore apoptotic function is a rational approach for treating cancer. With our increasing knowledge of the mechanisms of apoptosis regulation and of how apoptosis is disabled in cancer cells, numerous novel approaches targeting apoptotic pathways can now be exploited for cancer therapy. While most of these therapies are still in preclinical development, some have shown considerable promise and progressed into the clinic. This chapter summarizes the current knowledge of the apoptotic pathways and provides a selective review on the development of drugs that target the apoptotic machinery.

RESUMO

Clinical and experimental data now clearly indicate that chronic inflammation significantly contributes to cancer development. Emerging out of these studies is an appreciation that persistent humoral immune responses exacerbate recruitment and activation of innate immune cells in neoplastic microenvironments where they regulate tissue remodeling, pro-angiogenic and pro-survival pathways that together potentiate cancer development. Population-based studies examining individuals with chronic inflammatory disorders have revealed that states of suppressed cellular immunity, in combination with enhanced humoral immunity and humoral immunity-associated cytokines, cooperate and effectively suppress anti-tumor immune responses while simultaneously enhancing angiogenesis and presumably overall cancer risk in afflicted tissue. In addition, studies in transgenic mouse models of de novo organ-specific cancer development have revealed that inflammation mediated by immunoglobulins and immune complexes might be functionally significant parameters of tumor promotion and progression. These recent advances support the hypothesis that enhanced states of local humoral and innate immune activation, in combination with suppressed cellular immunity and failed cytotoxic T cell anti-tumor immunity, alter cancer risk and therefore represent powerful targets for anti-cancer immunotherapeutics.

RESUMO

Defective apoptosis not only promotes tumorigenesis, but also can confound chemotherapeutic response. Here we demonstrate that the proapoptotic BH3-only protein BIM is a tumor suppressor in epithelial solid tumors and also is a determinant in paclitaxel sensitivity in vivo. Furthermore, the H-ras/mitogen-activated protein kinase (MAPK) pathway conferred resistance to paclitaxel that was dependent on functional inactivation of BIM. Whereas paclitaxel induced BIM accumulation and BIM-dependent apoptosis in vitro and in tumors in vivo, the H-ras/MAPK pathway suppressed this BIM induction by phosphorylating BIM and targeting BIM for degradation in proteasomes. The proteasome inhibitor Velcade (P-341, Bortezomib) restored BIM induction, abrogated H-ras-dependent paclitaxel resistance, and promoted BIM-dependent tumor regression, suggesting the potential benefits of combinatorial chemotherapy of Velcade and paclitaxel.

RESUMO

Genomic instability is a hallmark of cancer development and progression, and characterizing the stresses that create and the mechanisms by which cells respond to genomic perturbations is essential. Here we demonstrate that antiapoptotic BCL-2 family proteins promoted tumor formation of transformed baby mouse kidney (BMK) epithelial cells by antagonizing BAX- and BAK-dependent apoptosis. Cell death in vivo correlated with hypoxia and induction of PUMA (p53 up-regulated modulator of apoptosis). Strikingly, carcinomas formed by transformed BMK cells in which apoptosis was blocked by aberrant BCL-2 family protein function displayed prevalent, highly polyploid, tumor giant cells. Examination of the transformed BMK cells in vivo revealed aberrant metaphases and ploidy changes in tumors as early as 9 d after implantation, which progressed in magnitude during the tumorigenic process. An in vitro ischemia system mimicked the tumor microenvironment, and gain of BCL-2 or loss of BAX and BAK was sufficient to confer resistance to apoptosis and to allow for accumulation of polyploid cells in vitro. These data suggest that in vivo, even in cells in which p53 function is compromised, apoptosis is an essential response to hypoxia and ischemia in the tumor microenvironment and that abrogation of this response allows the survival of cells with abnormal genomes and promotes tumorigenesis.

RESUMO

OBJECTIVE: To study the clinical manifestation, angiographic features, and prognosis of myocardial bridge. METHODS: A retrospective analysis was made on the data of the clinical manifestation, coronary angiography, and prognosis of 35 patients with myocardial bridge, 29 males and 6 females, with an average age of 52.0 +/- 9.5 years, out of 2 871 patients undergoing coronary angiography 1 January 1996 - 20 February 2001. RESULTS: The detection rate of myocardial bridge, mostly in the middle or distal parts of left anterior descending branch and 24 being isolated myocardial bridge, was 1.22% in coronary angiography. There was a significant difference in the extent of diameter stenosis during systolic stage between the group with atherosclerosis (68% +/- 15%, n = 15) and the group without atherosclerosis (54% +/- 14%, n = 20) in the vessel proximal to myocardial bridge (P < 0.01). The systolic diameter stenosis was more severe in the abnormal ECG group (63% +/- 13%, n = 12) than in the normal ECG group (54% +/- 14%, n = 12), P < 0.05. However, the systolic stenosis extent of myocardial bridge in the patients with typical angina pectoris (58% +/- 15%, n = 11) was not significantly different from that in the patients with atypical angina pectoris (54% +/- 15%, n = 13). The systolic stenosis extent of myocardial bridge were 69% +/- 9% (n = 7) and 58% +/- 16% (n = 26) in the patients with and without left ventricular wall hypertrophy respectively (P = 0.09). No malignant event occurred during the follow-up period of 3 - 50 months. CONCLUSION: (1) The more severe the extent of systolic diameter stenosis, the more severe the myocardial ischemia and the more the possibility of abnormal ECG. (2) Myocardial bridge tends to promote or accelerate the atherosclerosis of the vessels proximal to it. (3) Left ventricular wall hypertrophy may promote the formation of myocardial bridge clinically. (4) The prognosis of myocardial bridge is good.
