Household smoking bans reduce exposure to secondhand smoke in adult nonsmokers and children. To explore the process families go through in adopting voluntary household smoking restrictions, qualitative interviews were conducted with rural African American and White adults in 102 households. The study investigated how families decide to restrict smoking in the home, who has significant influence in the decision-making process, the kinds of disagreements families have about household smoking restrictions, and reasons some families never consider household smoking policies. These findings have implications for designing intervention strategies and messages to promote household smoking bans and help family members negotiate smoke-free homes. 相似文献
The fundamental view that colon adenocarcinomas arise only from conventional adenomas has been challenged by the now recognized
hyperplastic polyp-serrated adenoma-adenocarcinoma pathway. This article describes the history of the serrated adenoma (both
the traditional serrated adenoma and the sessile serrated adenoma) as well as the histology and endoscopic appearance of these
lesions in comparison with hyperplastic polyps and mixed polyps. Although the exact pathway is the subject of ongoing research,
compelling histologic associations and molecular phenotypes that define the model of the serrated polyp-carcinoma sequence,
including microsatellite instability, BRAF/KRAS mutations, and CpG island methylator phenotype, provide strong evidence that this is a genuine pathway. Management of serrated
neoplasia of the colon includes careful colonoscopy, complete removal of colonic polyps, sampling fields of diminutive polyps
of the rectosigmoid, and basing surveillance on histology of removed polyps. 相似文献
Introduction. Research in cancer care satisfaction itself is scarce; investigation of the role of ethnicity in care satisfaction is even rarer.
Objective. The present study examined relationships between ethnicity and satisfaction with care in a sample of 759 patients diagnosed with three different types of cancer (lung, head and neck, or gynecologic) from a large tertiary cancer hospital.
Method. Respondents filled out an assessment package that consisted of demographics, the Ware Patient Satisfaction Questionnaire-III (PSQ-III), 17 additional items constructed by the research team to examine other specific areas of satisfaction, and the Psychological Screen for Cancer (PSSCAN) Part C, to measure anxiety and depression.
Results. In a multivariate analysis, being non-White emerged as the primary predictor variable (beyond patient age, gender, marital status, education, cancer site, duration of illness, and presence or absence of metastases) of several of the PSQ-III satisfaction subscales.
Conclusion. Health care systems must consider how to become more responsive to the needs of all individuals, regardless of their ethnic background and levels of acculturation. 相似文献
This randomised controlled trial examined the impact of screening for distress followed by two different triage methods on clinically relevant outcomes over a 12-month period.
Methods:
Newly diagnosed patients attending a large tertiary cancer centre were randomised to one of the two conditions: (1) screening with computerised triage or (2) screening with personalised triage, both following standardised clinical triage algorithms. Patients completed the Distress Thermometer, Pain and Fatigue Thermometers, the Psychological Screen for Cancer (PSSCAN) Part C and questions on resource utilisation at baseline, 3, 6 and 12 months.
Results:
In all, 3133 patients provided baseline data (67% of new patients); with 1709 (54.5%) retained at 12 months (15.4% deceased). Mixed effects models revealed that both groups experienced significant decreases in distress, anxiety, depression, pain and fatigue over time. People receiving personalised triage and people reporting higher symptom burden were more likely to access services, which was subsequently related to greater decreases in distress, anxiety and depression. Women may benefit more from personalised triage, whereas men may benefit more from a computerised triage model.
Conclusion:
Screening for distress is a viable intervention that has the potential to decrease symptom burden up to 12 months post diagnosis. The best model of screening may be to incorporate personalised triage for patients indicating high levels of depression and anxiety while providing computerised triage for others. 相似文献
OBJECT: Although neuron transplantation to repair the nervous system has shown promise in animal models, there are few practical sources of viable neurons for clinical application and insufficient approaches to bridge extensive nerve damage in patients. Therefore, the authors sought a clinically relevant source of neurons that could be engineered into transplantable nervous tissue constructs. The authors chose to evaluate human dorsal root ganglion (DRG) neurons due to their robustness in culture. METHODS: Cervical DRGs were harvested from 16 live patients following elective ganglionectomies, and thoracic DRGs were harvested from 4 organ donor patients. Following harvest, the DRGs were digested in a dispase-collagenase treatment to dissociate neurons for culture. In addition, dissociated human DRG neurons were placed in a specially designed axon expansion chamber that induces continuous mechanical tension on axon fascicles spanning 2 populations of neurons originally plated approximately 100 microm apart. RESULTS: The adult human DRG neurons, positively identified by neuronal markers, survived at least 3 months in culture while maintaining the ability to generate action potentials. Stretch-growth of axon fascicles in the expansion chamber occurred at the rate of 1 mm/day to a length of 1 cm, creating the first engineered living human nervous tissue constructs. CONCLUSIONS: These data demonstrate the promise of adult human DRG neurons as an alternative transplant material due to their availability, viability, and capacity to be engineered. Also, these data show the feasibility of harvesting DRGs from living patients as a source of neurons for autologous transplant as well as from organ donors to serve as an allograft source of neurons. 相似文献
According to the data of the literature, the prevalence of pain in cancer patients at various stages of the disease and the settings of care range from 38 to 51%, with an increase of up to 74% in the advanced and terminal stages. Despite published World Health Organization (WHO) guidelines for pain management, 42 to 51% of cancer patients receive inadequate analgesia and 30% receive no analgesics at all. A 3-year Research Project "Towards a Pain-free Hospital", which began one year ago, is ongoing at the National Cancer Institute of Milan. The research is organized in three subsequent steps. In the 1st one, a series of patient- and staff-oriented evaluation tools are used to assess the level of appropriateness of pain communication, assessment, management and control of the in-patients. The 2nd step will implement a number of continuing educational interventions aimed at improving patient awareness and staff knowledge of the appropriate pain assessment and management in order to respond to the patient's pain problem. In the 3rd step, all the assessment tools used in step one will be applied again to establish the prevalence of pain, the causes and intensity and patient satisfaction with pain management and to evaluate the impact of the interventions performed during the 2nd step regarding the overall ability of our hospital to tackle pain emergency in the hospitalized cancer population. The results relative to the 1st step are herein reported, in particular as regards the study on prevalence, causes, severity of pain, the interference of pain with sleep, mood and concentration, the use of pain medications and the relief obtained, the structural validity and internal consistency of the assessment tool used. A total of 258 patients hospitalized for at least 24 h were interviewed by 9 physicians using a brief structured questionnaire prepared ad hoc: 51.5% of the patients presented pain during the previous 24 h caused by surgery (49.6%) or by the tumor mass itself (29.3%). Out of the 133 patients with pain, a high degree (much or very much) of pain at rest was present in 27.1% and pain on movement in 30.8%; 31.6% did not take any analgesic treatment, and 14.3% of the latter reported a high degree of pain at rest and 21.4% on movement. Pain interfered with sleep from much to very much in 28.8% and with irritability and nervousness in 15.9% of the patients. In the 91 patients taking analgesics, 57.2% reported a high degree of pain relief. A high degree of pain and interference, however, was associated with low relief levels. The assessment tool used was shown to have a good structural validity and internal consistency (Chrombach alpha index of interference scale = 0.73). Although the Milan Cancer Institute has the longest tradition in Italy of pain assessment by means of validated tools and pain management according to the WHO guidelines and educational efforts in this field, the results of the study clearly show that it is necessary to persevere with continuing educational and informative programs in order to reduce the frequency and severity of pain and thus improve the quality of life of in-patients. 相似文献
