RESUMO

Resistin is a protein involved in inflammation and angiogenesis processes and may play a role in the progression of colorectal cancer (CRC). However, it remains unclear whether resistin is associated with increased mortality after CRC diagnosis. We examined pre-diagnostic serum resistin concentrations in relation to CRC-specific and all-cause mortality among 1343 incident CRC cases from the European Prospective Investigation into Cancer and Nutrition cohort. For CRC-specific mortality as the primary outcome, hazard ratios (HRs) and 95% confidence intervals (95% CI) were estimated from competing risk analyses based on cause-specific Cox proportional hazards models and further in sensitivity analyses using Fine-Gray proportional subdistribution hazards models. For all-cause mortality as the secondary outcome, Cox proportional hazards models were used. Subgroup analyses were performed by sex, tumor subsite, tumor stage, body mass index and time to CRC diagnosis. Resistin was measured on a median of 4.8 years before CRC diagnosis. During a median follow-up of 8.2 years, 474 deaths from CRC and 147 deaths from other causes were observed. Resistin concentrations were not associated with CRC-specific mortality (HRQ4vsQ1 = 0.95, 95% CI: 0.73-1.23; Ptrend = .97; and HRper doubling of resistin concentration = 1.00; 95% CI: 0.84-1.19; P = .98) or all-cause mortality. Results from competing risk (sensitivity) analysis were similar. No associations were found in any subgroup analyses. These findings suggest no association between pre-diagnostic circulating resistin concentrations and CRC-specific or all-cause mortality among persons with CRC, and the potential insignificance of resistin in CRC progression.

RESUMO

BACKGROUND: Body mass index (BMI) and cardiometabolic comorbidities such as cardiovascular disease and type 2 diabetes have been studied as negative prognostic factors in cancer survival, but possible dependencies in the mechanisms underlying these associations remain largely unexplored. We analysed these associations in colorectal and breast cancer patients. METHODS: Based on repeated BMI assessments of cancer-free participants from four European countries in the European Prospective Investigation into Cancer and nutrition (EPIC) study, individual BMI-trajectories reflecting predicted mean BMI between ages 20 to 50 years were estimated using a growth curve model. Participants with incident colorectal or breast cancer after the age of 50 years were included in the survival analysis to study the prognostic effect of mean BMI and cardiometabolic diseases (CMD) prior to cancer. CMD were defined as one or more chronic conditions among stroke, myocardial infarction, and type 2 diabetes. Hazard ratios (HRs) and confidence intervals (CIs) of mean BMI and CMD were derived using multivariable-adjusted Cox proportional hazard regression for mean BMI and CMD separately and both exposures combined, in subgroups of localised and advanced disease. RESULTS: In the total cohort of 159,045 participants, there were 1,045 and 1,620 eligible patients of colorectal and breast cancer. In colorectal cancer patients, a higher BMI (by 1 kg/m2) was associated with a 6% increase in risk of death (95% CI of HR: 1.02-1.10). The HR for CMD was 1.25 (95% CI: 0.97-1.61). The associations for both exposures were stronger in patients with localised colorectal cancer. In breast cancer patients, a higher BMI was associated with a 4% increase in risk of death (95% CI: 1.00-1.08). CMDs were associated with a 46% increase in risk of death (95% CI: 1.01-2.09). The estimates and CIs for BMI remained similar after adjustment for CMD and vice versa. CONCLUSIONS: Our results suggest that cumulative exposure to higher BMI during early to mid-adulthood was associated with poorer survival in patients with breast and colorectal cancer, independent of CMD prior to cancer diagnosis. The association between a CMD diagnosis prior to cancer and survival in patients with breast and colorectal cancer was independent of BMI.

RESUMO

BACKGROUND: The pathogenesis of the development of IgA nephropathy has not been clear up to now. At present, some studies revealed that the mTOR pathway may participate in IgA nephropathy; however, the mechanism has not been systematically studied. In this study, we established an IgAN rat model to investigate the protective effects of rapamycin as a new type of immunosuppressant, as well as its therapeutic mechanisms. METHODS: After the establishment of IgA nephropathy model, rats were treated with different concentrations of rapamycin, and the protective effect of different concentrations of rapamycin on renal function of the rats was observed. The deposition of IgA was observed by immunofluorescence. The kidney expression of Akt and p70S6k proteins in mTOR pathway was examined using the western blot assay after rapamycin treatment. RESULTS: Morphology and immunofluorescence confirmed that the rat model of IgA nephropathy was successfully established. In particular, the level of proteinuria decreased with the increase of the dose of rapamycin, as well as the deposition of IgA in glomeruli. Moreover, the western blot analysis indicated that the expression of p70S6K in the downstream of mTOR pathway decreased and the upstream protein AKT of the mTOR pathway was overexpressed in the rats model. CONCLUSION: We found that rapamycin has protective effects in the IgA nephropathy rat model in a dose-dependent manner. In addition, the result of western blot assay suggested that rapamycin may display its therapeutic effects through interfering the AKT-mTOR-p70S6K signaling pathway.

RESUMO

AIMS AND OBJECTIVES: To investigate the knowledge and clinical practices of cardiovascular disease prevention among registered nurses who worked on three major clinical units in Beijing hospitals. BACKGROUND: Health education on cardiovascular disease prevention is an important component of nursing practice; however, Chinese registered nurses' knowledge and practice patterns have been poorly explored in previous studies. DESIGN: A cross-sectional study. METHODS: A stratified random sample of three hundred registered nurses was recruited from two tertiary hospitals in Beijing, China. A validated questionnaire was used to examine nurses' knowledge of cardiovascular disease risk factors, their practices and perceived barriers to cardiovascular disease prevention-related patient education. The differences in knowledge of cardiovascular disease risk factors and the practice pattern associated with cardiovascular disease prevention were compared among nurses who worked on three major clinical units. RESULTS: Questionnaires were completed by 273 registered nurses with a response rate of 91%. More than 75% of the registered nurses knew the cardiovascular disease risk factors; however, less than half knew the right target goals for cardiovascular disease risk factors. Notably, fewer than 70% of registered nurses routinely provided health education for cardiovascular disease prevention during their practice. There was inconsistency between registered nurses' knowledge of target goals for cardiovascular disease risk reduction and their education practices on cardiovascular disease prevention. The three major barriers to providing cardiovascular disease risk factor preventive education were lack of time, patients' reluctance to change lifestyle and lack of physicians' support. CONCLUSIONS: Not all of the registered nurses were motivated to educate and encourage patients to engage healthy lifestyle changes, even though most of them were knowledgeable about cardiovascular disease risk factors. A gap between the knowledge and practice for the prevention of cardiovascular disease was identified. RELEVANCE TO CLINICAL PRACTICE: The findings highlight the need to advocate for knowledge application and address knowledge deficits in the area of cardiovascular disease prevention among registered nurses.

RESUMO

BACKGROUND: Smartphone apps present a great opportunity for the management of cardiovascular disease (CVD) as the adoption of apps becomes increasingly popular in China. Yet, little is known about the status of CVD-related Smartphone apps in the country. The aim of this study was to examine the current status of CVD-related smartphone apps available for download in China. MATERIALS AND METHODS: Using CVD-related keywords written either in Chinese or English, the top 6 most popular smartphone app online stores in China were searched in September 2015. The information accountability of the selected apps was assessed with the Silberg scale. The key topic areas identified from the European Guidelines on cardiovascular disease prevention served to determine information coverage of the top 5 downloaded apps. RESULTS: The average Silberg score of 151 apps was 2.87 (out of 9) with most apps not revealing authors' qualifications and information references. There was also a lack of sponsorship disclosure and information update. Moreover, none of the top 5 downloaded apps covered all key areas of CVD management as recommended by the European Guidelines on cardiovascular disease prevention. There was little evidence of health professionals' involvement in the formation of the CVD-related apps. CONCLUSION: This study identified areas for improvement concerning information accountability and the scope of coverage of CVD-related apps downloadable in China. The findings may guide the future advancement of CVD-related apps and benefit CVD management in China.

RESUMO

AIMS: Postoperative delirium (POD) and declined cognitive function were common in patients (especially elderly patients) who underwent coronary artery bypass grafting (CABG), which may affect quality of life (QoL). The aim of this study was to determine the relationships among age, POD, declined cognitive function, and QoL in patients who underwent CABG. METHODS: Consecutive patients who underwent first time elective CABG and assessed for POD using Confusion Assessment Method for intensive care unit for 5 postoperative days from November 2013 to March 2015 were recruited. A cross-sectional study was conducted during April 2015 to assess their cognitive function and QoL, using the Telephone Interview for Cognitive Status Scale and Medical Outcomes Study 36-Item Short Form Health Survey. The relationships among age, POD, declined cognitive function, and QoL were tested using path analysis. RESULTS: Declined cognitive function was associated with poorer QoL. POD was associated with declined cognitive function but was not associated with poorer QoL. Ageing was not associated with QoL but was associated with POD and declined cognitive function. CONCLUSION: The QoL of patients developed delirium after CABG is determined by cognitive function after discharge. Necessary strategies should be implemented to prevent POD and declined cognitive function, especially in elderly patients.

RESUMO

AIM: To report a concept analysis of nursing-sensitive indicators within the applied context of the acute care setting. BACKGROUND: The concept of 'nursing sensitive indicators' is valuable to elaborate nursing care performance. The conceptual foundation, theoretical role, meaning, use and interpretation of the concept tend to differ. The elusiveness of the concept and the ambiguity of its attributes may have hindered research efforts to advance its application in practice. DESIGN: Concept analysis. DATA SOURCES: Using 'clinical indicators' or 'quality of nursing care' as subject headings and incorporating keyword combinations of 'acute care' and 'nurs*', CINAHL and MEDLINE with full text in EBSCOhost databases were searched for English language journal articles published between 2000-2012. Only primary research articles were selected. METHODS: A hybrid approach was undertaken, incorporating traditional strategies as per Walker and Avant and a conceptual matrix based on Holzemer's Outcomes Model for Health Care Research. RESULTS: The analysis revealed two main attributes of nursing-sensitive indicators. Structural attributes related to health service operation included: hours of nursing care per patient day, nurse staffing. Outcome attributes related to patient care included: the prevalence of pressure ulcer, falls and falls with injury, nosocomial selective infection and patient/family satisfaction with nursing care. CONCLUSION: This concept analysis may be used as a basis to advance understandings of the theoretical structures that underpin both research and practical application of quality dimensions of nursing care performance.

RESUMO

Within the context of contemporary nursing practice, bedside handover has been advocated as a potentially more suitable mode for achieving patient-centred care. Given that patients can play an important role in the process, better understanding of patients' perspectives of bedside handover could be a critical determinate for successful implementation of the practice. Using a phenomenological approach, this study attempted to explore patients' perceptions of bedside nursing handover. Four key themes emerged from the patient interviews: 'a more effective and personalised approach', 'being empowered and contributing to error minimization', 'privacy, confidentiality and sensitive topics', and 'training need and avoidance of using technical jargon'. Patients welcome bedside handover as they can be empowered through participation in the process. Nevertheless, attention is needed to ensure that adequate training is provided to nurses and to minimize the use of technical jargon so that handover is delivered with a professional and consistent approach.

RESUMO

The aim of this descriptive qualitative study was to explore perspectives of nurses and midwives towards the introduction of shift-to-shift bedside handover. Semistructured interviews with nurses (n = 20) and midwives (n = 10) occurred 12 months after the introduction of bedside handover. Data were analyzed using thematic content analysis. Two main themes were identified: enhanced individual patient care and documentation, along with improved patient-clinician partnerships; and protection of confidentiality and privacy. The newly introduced bedside handover model improved efficiency and accuracy of the handover process and led to the provision of safe, high-quality care. Development of ward-specific tools and relevant educational resources, along with clinical support, are identified as the facilitators to ensure the new model can be successfully integrated into normal clinical practice.

RESUMO

An 8-year-old girl with a skeletal Class III malocclusion was treated in 2 phases. Maxillary expansion and protraction were carried out as the early intervention. However, her maxillary hypoplasia and mandibular hyperplasia deteriorated with age. The phase 2 comprehensive treatment began with proper mechanics when she was 12 years old with growth potential. In the maxillary arch, an auxiliary rectangular wire was used with a round main wire and an opening spring to create space for the impacted teeth and to bodily move the anterior teeth forward. Decompensation of mandibular incisors and correction of the Class III malocclusion were achieved by short Class III elastics with light forces and a gentle interaction between the rectangular wires and the lingual root-torque slots. The phase 2 active treatment period was 4 years 8 months. The 2-year follow-up indicated that our treatment results were quite stable.
