OBJECTIVE: Thymic carcinoma is a rare mediastinal neoplasm with frequent pleural or pericardial dissemination. We retrospectively studied ten such cases and analyzed factors that influenced the survival of the patients. METHODS: Ten thymic carcinoma patients with dissemination have been treated since 1987. The clinical and pathological data were retrospectively reviewed. RESULTS: Pretreatment tumor biopsy was performed and demonstrated squamous cell carcinomas in nine and small cell carcinoma in one. In six of ten patients pleural or pericardial dissemination was clinically evident (cT4). These patients were basically regarded as inoperable and treated with chemotherapy and/or radiotherapy. Four other patients were diagnosed as cT3 preoperatively but were found to have dissemination at the time of thoracotomy. They underwent total resection of the thymic tumor and all visible pleural dissemination but without pericardial dissemination. Radiotherapy was performed pre-or postoperatively with or without chemotherapy. The 5-year survival rate in all patients was 42.0%. The patients with Masaoka stage IVa showed significantly better prognosis than the patients with stage IVb (MST, 69.7 months vs. 14.5 months; 5-year survival rate, 64.3% vs. 0%) (P = 0.03). The patients with cT3 disease showed significantly better prognosis (P = 0.016) than the patients with cT4 disease (MST, 69.7 months vs. 14.5 months; 5-year survival rate, 100% vs. 16.7%). CONCLUSIONS: Among thymic carcinoma patients with pleural or pericardial dissemination, there seem to be some patients who show good prognosis. These candidates are patients who underwent subtotal resection with disseminations that were identified only at the operation and without hematogenous or lymphogenous metastasis. 相似文献

Dissemination of evidence-based programs and policies is a critical final step in reducing the burden of cancer in the general
public. Yet, we have not been fully successful to date in improving clinical or public health practice by disseminating programs
found to be effective in research. Therefore, research is needed into the dissemination process and outcomes to enable better
efforts in the future. This paper explores the definitions and models used for dissemination, the designs of dissemination
studies, and possible research questions in dissemination research, all focused on cancer prevention and control. We hope
that this paper will encourage dissemination research in our field. 相似文献

BACKGROUND: The High 5, Low Fat Program (H5LF) for African American parents was developed in partnership with the Parents As Teachers program, and was designed to test a dietary intervention appropriate for national adoption. METHODS: H5LF used a group randomized, nested cohort design with 738 parents. Consistent with organizational goals and methods, parent educators delivered a dietary change program via personal visits, newsletters, and group meetings. Primary outcomes were reducing percentage calories from fat and increasing fruit and vegetable consumption among participating parents; intermediate aims included improving in nutrition-related skills and parental modeling of dietary behaviors. RESULTS: H5LF parents achieved a 0.53 increase in fruit and vegetable consumption (P = 0.03), and a higher proportion of H5LF parents reduced their intake to less than 30% calories from fat (chi(2) = 4.8, P < 0.03; -1.7% calories from fat, p = 0.07) and improved performance of dietary behaviors (F = 14.2, P = 0.004). Improvements in parental modeling were not statistically significant. CONCLUSIONS: H5LF is an effective intervention that is appropriate for national adoption by over 2000 Parents As Teachers sites with the potential to impact dietary intake of African American parents nationwide. 相似文献

BackgroundThough medication reviews have shown positive patient outcomes, they are still not widely implemented in community pharmacies. Published reviews on their implementation often include several other pharmacy services, making them non-specific. Using the Consolidated Framework for Implementation Research (CFIR) to focus solely on the experiences of different stakeholders with the implementation of medication reviews will help to better understand relevant facilitators and barriers.ObjectivesTo critically appraise, synthesise and present the available evidence on experiences of key stakeholders with the implementation of medication reviews and to identify barriers and facilitators to its implementation in community pharmacies.MethodsA systematic literature search was conducted in four databases for studies published in English, Spanish or German. Key search terms included: implementation, pharmac*, medication review, facilitator, barrier. Study selection, quality assessment and data extraction were performed by two independent reviewers. Findings were mapped directly against the constructs of the CFIR.ResultsOut of 924 retrieved records 24 articles from 9 countries met the inclusion criteria. Key facilitators identified included pharmacists' openness to practice change and a high degree of patient satisfaction post medication review. Attracting patients to the service was stated as challenging due to an unawareness of the scope and potential benefit of a medication review. The dominant barrier was inadequate remuneration, as it impacted all additional resourcing and ultimately the viability of the service. Further barriers included difficult professional relationships with doctors and little mandate from health authorities. Most reports were from the employed pharmacists’ perspective and concerned the inner setting, other perspectives were under-reported.ConclusionsResults of this systematic review illustrate different stakeholders' experiences and add to the understanding of challenges in the implementation process. Nevertheless, findings also highlight how scarce reporting of external stakeholders’ views is and that filling this gap can unveil hidden barriers and facilitators.RegistrationPROSPERO register (CRD 42019122836) 相似文献

《Journal of anxiety disorders》2013,27(8):802-804
Dissemination methods are used to increase the likelihood that a given treatment or form of clinical practice is implemented by clinicians in the community. Therapist training in treatment methods is an important component of dissemination. Successful dissemination also requires that roadblocks to treatment implementation are identified and circumvented, such as misconceptions that clinicians might hold about a given treatment. The present article offers a commentary on the papers included in the special issue on treatment dissemination for anxiety disorders. Most papers focus on issues concerning the training and education of clinicians with regard to exposure therapy. Training and education is an important step but should be part of a broad, multifaceted approach. There are several other important methods of treatment dissemination, including methods developed and implemented with success by the pharmaceutical industry, might also be used to disseminate psychosocial therapies. Optimal dissemination likely requires a broad perspective in which multiple dissemination methods are considered for implementation. 相似文献

Staphylococcus aureus is a notorious opportunistic pathogen causing a plethora of diseases. Recent research established that once phagocytosed by neutrophils and macrophages, a certain percentage of S. aureus is able to survive within these phagocytes which thereby even may contribute to dissemination of the pathogen. S. aureus further induces its uptake by otherwise non-phagocytic cells and the ensuing intracellular cytotoxicity is suggested to lead to tissue destruction, whereas bacterial persistence within cells is thought to lead to immune evasion and chronicity of infections. We here review recent work on the S. aureus host pathogen interactions with a focus on the intracellular survival of the pathogen. 相似文献

We report a case of nocardiosis in an immunosuppressed elderly patient who presented with prolonged pyrexia. Nocardia asteroides was isolated from the thyroid, with CT scan evidence of dissemination to the brain, abdomen and lungs. The patient succumbed to illness despite aggressive therapy. Autopsy could not be performed. To the best of our knowledge, this is the first reported case from India, on Nocardia asteroides affecting the thyroid tissue. 相似文献
