When economists ask questions about basic financial principles, most ordinary people answer incorrectly. Economic experts call this condition "financial illiteracy," which suggests that poor financial outcomes are due to a personal deficit of reading-related skills. The analogy to reading is compelling because it suggests that we can teach our way out of population-wide financial failure. In this comment, we explain why the idea of literacy appeals to policy makers in the advanced industrial nations. But we also show that the narrow skill set laid out by economists does not satisfy the politically inclusive definition of literacy that literacy studies fought for. We identify several channels through which people engage with ideas about finance and demonstrate that not all forms of literacy will lead people to the educational content prescribed by academic economists. We argue that truly financial literate people can defy the demands of financial theory and financial institutions.

Until recently, bacteria have been studied in terms of their roles in infectious diseases and mainly by using isolation and culture methods. However, in practice, many bacteria existing on the earth are difficult to isolate and culture, and thus only a limited number of them have been studied to date. On the other hand, in 2005, the next-generation sequencing technology became generally available, and since then genomic analysis of bacterial flora has become widespread. As a result, it has been revealed that the lower respiratory tract, which was previously thought to be sterile, in fact has bacterial flora (a microbiome) with a high level of biodiversity. In addition, it has been found that various diseases develop and worsen depending on the balance of the bacterial flora, and in recent years, a relationship has been established between various disorders. Recent research on cancer-associated microbial communities has elucidated the reciprocal interactions among bacteria, tumors and immune cells, the bacterial pathways associated with induction of oncogenesis, and their translational significance. Nevertheless, despite the increasing evidence showing that dysbiosis is associated with lung oncogenesis, the detailed mechanisms remain to be fully elucidated. Microorganisms seem to trigger tumor initiation and progression, presumably through the production of bacterio-toxins and other pro-inflammatory factors. The purpose of this review is to present a context for the basic mechanisms and molecular functions of the airway microbiome in oncogenesis, in an effort to prevent cancer by strategies utilizing the airway microbiota, as well as summarizing the mechanisms wherein the microbiome acts as a modulator of immunotherapies in lung cancer.

Properly organised regional centres would involve teams of interested cardiothoracic surgeons working with, and possibly led by, specialist pure thoracic surgeons to common protocols. A great deal of time would be saved by specialist staff reducing travelling times to outlying units. Data collection and administration would be greatly enhanced and the potential for collaborative work significantly increased. Unfortunately, there has been little if any coherent planning for a national strategy for the delivery of such care in the United Kingdom.

The occurrence of colon cancer in four Scandinavian (Nordic) countries--Finland, Denmark, Norway and Sweden--is described. In addition, a number of correlations relevant to the etiology of colon cancer are presented. The observable differences in the risk for colon cancer among the Nordic countries can largely be accounted for by socioeconomic factors.

Our purpose is to demonstrate that some human colon cancer cells are able to express the same differentiation features as normal intestinal epithelial cells and to report experimental data which suggest that these particular cells are spontaneously resistant and adaptable to anticancer drugs. The concept of normal differentiation of colon cancer cells is supported by observations made with two cultured cell lines, Caco-2 and HT-29. The cell line Caco-2 expresses spontaneously and homogeneously an enterocytic differentiation. The cell line HT-29 is heterogeneous as it contains a small proportion (< 5%) of differentiated cells of either enterocytic or mucus-secreting type. Homogeneous populations of differentiated HT-29 cells of either type have been isolated by pressure selection. In order to investigate whether the pressure associated with anti-cancer drugs would result in the selection of differentiated populations, HT-29 cells were cultured in the presence of increasing concentrations of methotrexate and 5-fluorouracil. The resulting resistant populations were found to be totally differentiated. This supports the view that the small proportion of parental cells which are able to differentiate are also able to spontaneously resist to drug pressure. These results imply that the concept of cellular differentiation should be considered by pathologists. They also imply that basic research should be developed in order to unravel which mechanisms of drug resistance are specifically associated with the ability of the cells to differentiate.

This article is a wide-ranging overview of the field of healthcare financing, health economics and the development of financial management. It vividly demonstrates that all healthcare systems have too many demands and too few resources, and that problems can manifest themselves in different forms depending on the precise funding structure of the health service concerned.

Accessibility of powerful computers and availability of so-called big data from a variety of sources means that data science approaches are becoming pervasive. However, their application in mental health research is often considered to be at an earlier stage than in other areas despite the complexity of mental health and illness making such a sophisticated approach particularly suitable. In this Perspective, we discuss current and potential applications of data science in mental health research using the UK Clinical Research Collaboration classification: underpinning research; aetiology; detection and diagnosis; treatment development; treatment evaluation; disease management; and health services research. We demonstrate that data science is already being widely applied in mental health research, but there is much more to be done now and in the future. The possibilities for data science in mental health research are substantial.

The incidence of thyroid cancer has increased dramatically, yet the mortality has remained unchanged. There remain many challenges and "difficult problems" in diagnosing and treating patients with differentiated thyroid cancer (DTC). A significant percentage of patients with DTC will present with a thyroid nodule and an indeterminate fine needle aspiration biopsy underscoring the importance of proper evaluation and management. It is important when considering the extent of thyroidectomy and the management of lymph node metastases to balance the outcome of treatment in terms of recurrence and mortality with the morbidity of the procedure. Total thyroidectomy and lymphadenectomy for macroscopic lymph node metastases appear to be the optimal therapy for most patients with DTC. Preservation of function is a priority in managing patients with DTC invading the recurrent laryngeal nerve, trachea, esophagus, or the larynx.

Paraneoplastic syndromes occur in approximately 10% of all patients with lung cancer. They can be the first manifestation of the disease or of a recurrence. Endocrine, haematological, neuromuscular, dermatological, renal, and metabolic syndromes as well as syndromes involving the connective tissue and constitutional syndromes can be distinguished based on their clinical symptoms. In this review, the epidemiology, pathogenesis, clinical signs and treatment options for the clinically important paraneoplastic syndromes in lung cancer are discussed.

Thyroid cancer is the most frequently diagnosed endocrine cancer and causes more deaths than all other endocrine cancers combined. Research findings support the concept that a subpopulation of thyroid cancer cells displays properties characteristic of stem cells. These putative cancer-forming entities drive tumorigenesis as a result of their dual ability to undergo self-renewal and to differentiate into various types of cancer cells; they also mediate metastasis and are resistant to the effects of chemotherapy and radiation therapy. This Review discusses the cellular origin of thyroid cancer and the properties of the thyroid cancer stem cell niche. The article critically evaluates the methods used to identify molecular markers expressed by thyroid-cancer-initiating cells and outlines prospective therapeutic strategies to directly target these cells. Stem-cell technology offers an unprecedented opportunity to investigate these crucial cancer stem cell populations and to advance understanding of the molecular mechanisms that control disease processes. Such knowledge could potentially lead to the development of more effective and safer treatment regimens for late-stage thyroid cancer than are currently available.

One hundred forty-eight cases of colon carcinoma were subjected to further pathologic study. Survival was correlated with stage and grade of the tumor and with the number of involved lymph nodes. In addition, cases were assessed as to the extent of local chronic inflammatory reaction about the lesion and the degree of sinus histiocytosis in draining lymph nodes. A correlation was possible between grading, staging, extent of lymph node involvement, and survival. A substantial difference in five-year survival was shown when local inflammatory reaction was present and when sinus histiocytosis was observed. The presence of both of these factors further improved survival. An adequate evaluation of these factors, both individually and in combination, should improve our ability to assess prognosis in colon cancer.

We describe herein dermatomyositis (DM) associated with thyroid cancer in a 54-year-old woman. She was resistant to corticosteroids at first, but removal of the coexisting cancer resulted in improvement of DM. Reports on the association of DM with thyroid cancer are very few. However, recently, increasing incidence of thyroid cancer is pointed out. It is thought that increasing incidence reflects increased detection of subclinical disease due to increased diagnostic scrutiny, not an increase in the true occurrence of thyroid cancer. Thus, DM associated with thyroid cancer may be more frequent than we generally expected. We recommend that thyroid studies should be included in cancer investigations, particularly in DM cases resistant to corticosteroids.

Recent molecular studies have described a number of abnormalities associated with the progression and dedifferentiation of thyroid carcinoma. These distinct molecular events are often associated with specific stages of tumor development. A better understanding of the mechanisms involved in thyroid cancer pathogenesis may help to translate these discoveries toward improvements in patient care.

We reviewed the descriptive epidemiology of thyroid cancer using data from the Cancer Registry of the Canton of Vaud, Switzerland, a consistently well-surveilled population with relatively high rates of the disease, between 1974 and 1998, on the basis of a total of 596 registered cases. Overall thyroid cancer incidence tended to increase moderately in both genders over the 25-year period considered, to reach rates of 5.4 and 2.0 per 100,000 (world standard) in females and males, respectively. There were also changes in histologic classification, with some increases in papillary neoplasms and corresponding decreases in other and unclassified ones. Ten-year relative survival rates for cases diagnosed in 1988-1993 were 94% for papillary cancer in females and 69% in males, and 59% for follicular cancer in females. Corresponding figures were 12% for undifferentiated, and 31% for other and unspecified neoplasms in both sexes combined. Multivariate analysis confirmed the unfavorable influence of male gender (hazard ratio [HR] = 1.9), elderly age (HR = 16.5 for age > or = 65 vs. < 45 years) and undifferentiated histotype (HR = 3.5 vs. papillary) on the long-term prognosis of thyroid cancer, and showed no consistent evidence of appreciably improved prognosis over more recent calendar periods.

Genome-wide association studies (GWASs) have identified several single-nucleotide polymorphisms (SNPs) influencing the risk of thyroid cancer (TC). Most cancer predisposition genes identified through GWASs function in a co-dominant manner, and studies have not found evidence for recessively functioning disease loci in TC. Our study examines whether homozygosity is associated with an increased risk of TC and searches for novel recessively acting disease loci.

Thyroid tumorigenesis and carcinogenesis accompany progressive loss of thyroid-specific differentiated functions. Some thyroid cancers are or become dedifferentiated, and they become refractory to efficacy-proven conventional therapies such as radioiodine ablation therapy and thyrotropin (TSH)-suppressive therapy. Redifferentiation therapy by either redifferentiating agents or gene transfer of differentiation-related genes may retard tumor growth and make tumors respond to conventional therapies.

We present an automated method for measuring media bias. Inferring which newspaper published a given article, based only on the frequencies with which it uses different phrases, leads to a conditional probability distribution whose analysis lets us automatically map newspapers and phrases into a bias space. By analyzing roughly a million articles from roughly a hundred newspapers for bias in dozens of news topics, our method maps newspapers into a two-dimensional bias landscape that agrees well with previous bias classifications based on human judgement. One dimension can be interpreted as traditional left-right bias, the other as establishment bias. This means that although news bias is inherently political, its measurement need not be.

Bronchoscopic techniques have seen significant advances in the last decade. The development and refinement of different types of endobronchial ultrasound and navigation systems have led to improved diagnostic yield and lung cancer staging capabilities. The complication rate of these minimally invasive procedures is extremely low as compared to traditional transthoracic needle biopsy and surgical sampling. These advances augment the safe array of methods utilized in the work up and management algorithms of lung cancer.

The objectives for this longitudinal study were to: (a) compare colon cancer patients' and their spouses' appraisal of illness, resources, concurrent stress, and adjustment during the first year following surgery; (b) examine the influence of gender (male vs female) and role (patient vs spouse caregiver) on study variables; (c) assess the degree of correlation between patients' and spouses' adjustments; and (d) identify factors that affect adjustment to the illness. Fifty-six couples were interviewed at one week post diagnosis, and at 60 days and one year post surgery. Based on a cognitive-appraisal model of stress, the Smilkstein Stress Scale was used to measure concurrent stress; the Family APGAR, Social Support Questionnaire, and Dyadic Adjustment Scale were used to measure social resources; the Beck Hopelessness Scale and Mishel Uncertainty in Illness Scales were used to measure appraisal of illness; and the Brief Symptom Inventory and Psychosocial Adjustment to Illness Scale were used to measure psychosocial adjustment. Repeated Measures Analysis of Variance indicated that spouses reported significantly more emotional distress and less social support than patients. Gender differences were found, with women reporting more distress, more role problems, and less marital satisfaction, regardless of whether they were patient or spouse. Both patients and spouses reported decreases in their family functioning and social support, but also decreases in emotional distress over time. Moderately high autocorrelations and modest intercorrelations were found among and between patients' and spouses' adjustment scores over time. The strongest predictors of patients' role adjustment problems were hopelessness and spouses' role problems. The strongest predictors of spouses' role problems were spouses' own baseline role problems and level of marital satisfaction. Interventions need to start early in the course of illness, be family-focused, and identify the couples at risk of poorer adjustment to colon cancer.

Data on 117 male patients with thyroid cancer (1994-2004) have been assessed. It was found that thyroid cancer often engenders in the nodular formation it males. Early-stage cancers were detected in 63 cases (54.9%). Radiotherapy as a component of combined treatment was the most popular modality (43.2%), due to the malignant character of locally-advancer tumor. Ten-year survival was in 65.2%, while, in 11.9%, radical surgery was not indicated.

In non-small-cell lung cancer (NSCLC), the identification of oncogenic driver mutations led to the definition of different clinical entities with different therapeutic opportunities, as demonstrated in patients harboring EGF receptor (EGFR) mutations or anaplastic lymphoma kinase translocations. Human EGFR2 (or HER2) has an established role as a prognostic and predictive factor in breast cancer. Although HER2 deregulation, including overexpression, amplification and mutation, has been described in NSCLC, its role as a therapy biomarker remains undefined. In the last few years, there has been a growing interest on HER2 mutation, with few anecdotal or retrospective studies suggesting a relevant role for this biomarker. This review discusses the prognostic and predictive impact of HER2 deregulation and the clinical implications of anti-HER2 strategies in NSCLC.

Whereas preemptive screening for the presence of lymph node and lung metastases is standard-of-care in thyroid cancer patients, bone metastases are less well studied and are often neglected in thyroid cancer patient surveillance. Bone metastases in thyroid cancer are, however, independently associated with poor/worse prognosis with a median overall survival from detection of only 4 years despite an otherwise excellent prognosis for the vast majority of thyroid cancer patients. In this review we summarize the state of current knowledge as pertinent to bony metastatic disease in thyroid cancer, including clinical implications, impacts on patient function and quality of life, pathogenesis, and therapeutic opportunities, proposing approaches to patient care accordingly. In particular, bone metastasis pathogenesis appears to reflect cooperatively between cancer and the bone microenvironment creating a "vicious cycle" of bone destruction rather than due exclusively to tumor invasion into bone. Additionally, bone metastases are more frequent in follicular and medullary thyroid cancers, requiring closer bone surveillance in patients with these histologies. Emerging data also suggest that treatments such as multikinase inhibitors (MKIs) can be less effective in controlling bone, as opposed to other (e.g. lung), metastases in thyroid cancers, making special attention to bone critical even in the setting of active MKI therapy. Although locoregional therapies including surgery, radiotherapy and ablation play important roles in palliation, antiresorptive agents including bisphosphonates and denosumab appear individually to delay and/or lessen skeletal morbidity and complications, with dosing frequency of every 3 months appearing optimal; their early application should therefore be strongly considered.

With the current trend of alarming rise in obesity rates, the health impacts of excess weight will become more apparent. While an increased incidence of cardiovascular disease and diabetes mellitus has been well documented, the association between obesity and carcinogenesis is just being appreciated and is receiving increasing attention. The current review focuses on the evidence linking thyroid cancer with obesity. We conclude that there is sufficient evidence that obesity can predispose to an increased risk of thyroid cancer in both men and women. This population-based association is mainly explained at a biological level through specific obesity-related endocrinopathies.

Over the past 30 years, rectal cancer surgery has been standardized by total mesorectal excision. More recently, some have suggested that colon cancer surgery should be standardized by complete mesocolic excision (CME) with central vascular ligation (CVL), especially in Western countries. Surgeons undertaking CME with CVL report optimal outcomes. Sharp dissection within the embryological plane and high vascular ligation at the vessel origin are essential. In Japan, a similar concept, D3 dissection, has been adopted for decades. Although both surgical procedures are similar, distinct differences exist. Some surgeons are confused about the principles and practice of these two procedures. As well as overviewing the theory behind CME with CVL and D3 dissection, the technical details of both procedures are described.

67 segments of rectum and sigmoid removed surgically because of carcinoma were examined: the surface of intestinal mucosa stained with methylene-blue was studied in order to determine the number and localization of focal changes in the macroscopically unchanged areas. Colon microscopy was performed clinically in 24 patients with carcinoma of the rectum and in 24 control individuals. 28 hyperplastic polyps and 1037 microscopic hyperplastic foci were found in operative material. An active metabolism is established by means of electron autoradiography in the cells of hyperplastic focus. Areas of dysplastic epithelium were rarely found in big hyperplastic polyps. Areas of diffuse hyperplasia (transitional mucosa) with crypt deepening and presence of a high number of goblet cells were found near tumour. A certain role of hyperplastic processes in carcinogenesis is forwarded. Numerous microscopic changes in the mucosa epithelium may testify against the carcinoma development de novo.

The Clinical Outcomes of Surgical Therapy Group (COST) trial published in 2004 demonstrated that minimally invasive surgery (MIS) for colorectal cancer provided equivalent oncologic results and better short-term outcomes when compared to open surgery. Before this, MIS comprised approximately 3% of colorectal cancer cases. We hypothesized that there would be a dramatic increase in the use of MIS for colon cancer after this publication.
