Brachytherapy (BT) is a minimally invasive anticancer radiotherapeutic modality where the tumor is directly irradiated via a radioactive source that is precisely implanted in or adjacent to the tumor. BT for lung cancer may be conducted in the form of endobronchial BT and radioactive seed implantation (RSI-BT), mainly for nonsmall cell lung cancer (NSCLC). For patients with early-stage lung cancer who are not suitable for surgery or external beam radiotherapy (EBRT), BT may be used as an alternative treatment, and curative results could be achieved in certain patients with cancer confined to the trachea lumen. For patients with locally advanced/metastatic lung cancer, BT could be selectively applied alone or as a boost to EBRT, which could improve the local tumor control and patient's survival. In addition, BT is also useful as a salvage treatment in select patients with locally recurrent/residual lung cancer that failed other treatments (e.g., surgery, chemotherapy, and EBRT). However, clinical outcomes are mainly obtained from retrospective studies. Prospective studies are limited and needed. In recent years, the introduction of modern image guidance, novel radioactive seeds, BT treatment planning systems (BT-TPS), after-loading technique, and three-dimensional printing template (3D-PT) assistance, among others, have potentially improved the clinical outcomes of BT. However, a comprehensive review of BT with newly published literature was lacking. This review is to discuss BT for NSCLC based on recent literature published in PubMed.

The overall five year survival of patients with colorectal cancer is excellent compared with other major visceral malignancies. This is attributable to effect surgical treatment, yet the death rate per 100,000 population has improved little in recent decades, stimulating a search for adjuvant treatment modalities until a better understanding of etiology and pathogenesis results in prevention of earlier diagnosis. Combination of the known cancerocidal effect of ionizing radiation and surgical excision has been used sporadically for over six decades, but only recently has this combined modality therapy been studied in a scientific manner. Numerous variables such as source of radiation, total tumor dose, dose-time factors, location of portals of treatment, size and shape of radiation fields, and the radiation-surgery sequence are now being studied. Current information leaves little doubt of the effectiveness of this combined modality therapy in selected patients. Controlled clinical trials must continue in order to obtain more solid data, which hopefully will eventually result in substantially improved survival.

The authors have assembled detailed family histories of cancer on 857 cancer probands, of whom 180 manifested colorectal carcinoma. This study determines if some families had a greater risk for colorectal cancer than others, and if so, what factors were associated with an increase in risk. To test for the possibility of heterogeneity of risk, a parameter called the Z-score, was calculated for each family. The Z-score is a measure of the number of cancer cases in the family adjusted for the number of expected cases. A permutation test was employed to test whether or not the variance of Z-scores from the sample was greater then expected by random chance. The variance for families ascertained through colon cancer probands, but not in any of the other groups, was significantly increased. Of the colon group, 10.6% fell into a high-risk category, as did 5.56% of the rectal cancer families, but only 3.95% of the other groups combined were at high risk. Anatomic sites (in the proband) with the highest Z-score variances were sigmoid and transverse colon, whereas lower variances were seen for cecum and descending colon. Risk status therefore may be partially dependent upon exact anatomic sites within the colon. The effect of proband's age of diagnosis was not significant, but did show the possibility of an effect on heterogeneity of risk for both the younger and older groups.

Microgravity in space or simulated by special ground-based devices provides an unusual but unique environment to study and influence tumour cell processes. By investigating thyroid cancer cells in microgravity for nearly 20 years, researchers got insights into tumour biology that had not been possible under normal laboratory conditions: adherently growing cancer cells detach from their surface and form three-dimensional structures. The cells included in these multicellular spheroids (MCS) were not only altered but behave also differently to those grown in flat sheets in normal gravity, more closely mimicking the conditions in the human body. Therefore, MCS became an invaluable model for studying metastasis and developing new cancer treatment strategies via drug targeting. Microgravity intervenes deeply in processes such as apoptosis and in structural changes involving the cytoskeleton and the extracellular matrix, which influence cell growth. Most interestingly, follicular thyroid cancer cells grown under microgravity conditions were shifted towards a less-malignant phenotype. Results from microgravity research can be used to rethink conventional cancer research and may help to pinpoint the cellular changes that cause cancer. This in turn could lead to novel therapies that will enhance the quality of life for patients or potentially develop new preventive countermeasures.

Numerous biologic processes and such diseases as cancer depend on activation of tyrosine kinase receptors. The RET tyrosine kinase receptor was discovered two decades ago as a transforming gene and was subsequently implicated in the formation of papillary and medullary thyroid carcinoma. This article examines the data about the mechanism of activation of downstream signal transduction pathways by RET oncoproteins. Collectively, these findings have advanced the understanding of the processes underlying thyroid carcinoma formation.

The epidemiology of lung cancer has changed in the last years in several countries all over the world. In the 19th century, the lung cancer was rare but it incidence increase drastically during the 20th century, and the tendency is to continue in the 20th century. Actually the lung cancer's incidence and mortality are higher in the developed countries, especially in Europe and Unites States of America, with a increasing in the women incidence. These geographic differences and gender differences are related with smoking habits. Women begin to smoke earlier and have more difficulty to stop, because of problems related with obesity; they have more sensibility to the carcinogens and the risk of lung cancer is 1.5 times higher than the men with the same habits. Adenocarcinoma is the more frequent histological type in young people, in the total of the women and in non-smokers. Many factors since tobacco, home and professional pollution, nutritional, associated diseases even genetic and hormonal factors have been investigated to define its influence in development in women lung cancer. It specificity in women with lung cancer is the common problem for the medical people to treat this disease (pathology).The literature about this problem is not clear, and is necessary to advance with many studies in this area with the objective to clarify this important question.

Paraneoplastic syndromes (PNS) are a relatively common manifestation of cancer, and in some cases they may be the first symptom. Lung cancer has the highest incidence of paraneoplastic syndrome. This fact is important considering a non explained endocrinological and neurological syndrome, it may facilitate a prompt diagnosis, and in some cases an adequate treatment. PNS evolution seems to be parallel to the subjacent cancer. PNS management requires specific measures, because in some cases, it may compromise the patient life. Neurological and endocrinological PNS associated to lung cancer are revised, and diagnosis and treatment of them are updated.

One of the fields of medicine in which artificial intelligence techniques have made progress is ophthalmology. Artificial intelligence (A.I.) applications for preventing vision loss in eye illnesses have developed quickly. Artificial intelligence uses computer programs to execute various activities while mimicking human thought. Machine learning techniques are frequently utilized in the field of ophthalmology. Ophthalmology holds great promise for advancing artificial intelligence, thanks to various digital methods like optical coherence tomography (OCT) and visual field testing. Artificial intelligence has been used in ophthalmology to treat eye conditions impairing vision, including macular holes (M.H.), age-related macular degeneration (AMD), diabetic retinopathy, glaucoma, and cataracts. The more common occurrence of these diseases has led to artificial intelligence development. It is important to get annual screenings to detect eye diseases such as glaucoma, diabetic retinopathy, and age-related macular degeneration. These conditions can cause decreased visual acuity, and it is necessary to identify any changes or progression in the disease to receive appropriate treatment. Numerous studies have been conducted based on artificial intelligence using different algorithms to improve and simplify current medical practice and for early detection of eye diseases to prevent vision loss.

Thyroid nodules are common, and the accurate diagnosis of cancer or benign disease is important for the effective clinical management of patients. Molecular markers are a helpful diagnostic tool, particularly for cytologically indeterminate thyroid nodules. In the past few years, significant progress has been made in developing molecular markers for clinical use in fine-needle aspiration specimens, including gene mutation panels and gene expression classifiers. With the availability of next generation sequencing technology, gene mutation panels can be expanded to interrogate multiple genes simultaneously and to provide yet more accurate diagnostic information. In addition, recently several new molecular markers of thyroid cancer have been identified that offer diagnostic, prognostic, and therapeutic information that might be of value in guiding individualized management of patients with thyroid nodules.

Lung cancer is by far the most common form of cancer worldwide and in Germany is now "only" still the commonest cause of death from cancer. The most important single risk factor is smoking but in selected population groups, for example in the professional area, other factors can also play a role which cannot be ignored and open up a corresponding potential for prevention. Effective early detection procedures are at present unknown. The most promising, however, is multislice computed tomography (MSCT) which for this reason is presently being tested for effectiveness in several large research projects. The results are not expected for some years. Until then the early detection of lung cancer with MSCT cannot be considered suitable for routine use but can only be justified within the framework of research studies.

Development and progression of many malignancies, including colorectal cancer, are associated with activation of multiple signaling pathways. Therefore, inhibition of these signaling pathways with noncytotoxic natural products represents a logical preventive and/or therapeutic approach for colon cancer. Curcumin and resveratrol, both of which inhibit the growth of transformed cells and colon carcinogenesis, were selected to examine whether combining them would be an effective preventive and/or therapeutic strategy for colon cancer. Indeed, the combination of curcumin and resveratrol was found to be more effective in inhibiting growth of p53-positive (wt) and p53-negative colon cancer HCT-116 cells in vitro and in vivo in SCID xenografts of colon cancer HCT-116 (wt) cells than either agent alone. Analysis by Calcusyn software showed synergism between curcumin and resveratrol. The inhibition of tumors in response to curcumin and/or resveratrol was associated with the reduction in proliferation and stimulation of apoptosis accompanied by attenuation of NF-kappaB activity. In vitro studies have further demonstrated that the combinatorial treatment caused a greater inhibition of constitutive activation of EGFR and its family members as well as IGF-1R. Our current data suggest that the combination of curcumin and resveratrol could be an effective preventive/therapeutic strategy for colon cancer.

Colorectal cancer remains a major health problem. Few therapies are effective apart from surgery, and survival has increased little in recent years. This is despite the fact that screening by colonoscopy can potentially remove nearly all colorectal tumours before they become malignant. Molecular genetics has identified some inherited mutations (such as at APC and the mismatch repair loci) that predispose to colon cancer and some somatic mutations (such as at APC and p53) that cause sporadic colon tumours. We review the likely role of these and other genes in colorectal tumorigenesis. We also highlight areas of relative ignorance in colon cancer and emphasise that many important genes, especially those that cause invasion and metastasis, remain to be identified. Colorectal cancer is, however, a well characterised tumour, as regards both its natural history and its histopathology; there are consequently good prospects for advances in colon cancer genetics, with probable benefits for its treatment. We anticipate: (a) that new genes predisposing to colon tumours, including those conferring relatively minor risks, will be characterised; (b) genes and proteins important in invasion and metastasis will be identified; (c) the network of protein interactions in which molecules such as APC are involved will be elucidated; (d) large-scale studies of somatic mutations in tumours will provide accurate predictions of prognosis and suggest optimal therapeutic regimens; and (e) new potential targets for therapy will be identified. Whilst molecular genetics is by no means sufficient for progress in preventing and treating colon cancer, it is a necessary and central part of such advances.

Reoperation was performed in 110 of 185 patients with a differentiated thyroid carcinoma. In 25 patients (23 per cent) the indication for reintervention was a large thyroid remnant and in the other 85 (77 per cent) persistent or recurrent cancer was suspected. In 32 (29 per cent) of the 110 patients undergoing reoperation no evidence of cancer tissue was found. Tumour tissue in 33 patients (30 per cent) was resectable. Of 45 patients (41 per cent) with residual tumour after operation 24 showed only occult thyroid carcinoma with a raised serum thyroglobulin level. Eight of 21 patients with macroscopically persistent tumour died from the disease during a mean follow-up of 2.3 years. In 13 of 38 patients the investigated recurrent tumours were histologically less differentiated than the primary lesions, stressing the importance of total tumour clearance. The treatment of choice for persistent and recurrent differentiated thyroid carcinoma is surgical reintervention, if feasible, before radioiodine and radiation therapy are considered.

Cryosurgery is suited for patients with lung cancer who are not considered for lung resection because of the advanced stage of the disease or the patient's poor general condition or poor respiratory function and with tumor recurrence following radiotherapy, chemotherapy or lung resection, and those patients who have localized lung cancer but refuse to receive operative therapy. Procedures of cryosurgery for lung cancer can be performed through endobronchial, direct intrathoracic (at exploratory thoracotomy) or percutaneous routes depending upon location and size of tumor. Six hundred and twenty-five patients with Non-small cell lung cancer (NSCLC) received percutaneous cryoablation in Fuda Cancer Hospital Guangzhou, China. One hundred and fifty patients were followed-up for 12 to 38 months. Results showed that 1-, 2-, and 3-year survival rates were 64%, 45% and 32%, respectively. The adverse effects after cryosurgery of lung cancer include haemoptysis, pneumothorax, bloody thorax, pleural effusion and pulmonary infection which are generally mild, transient, and recovery with symptomatic management. In vitro studies have shown cryotherapy of lung cancer cells can improve the immune system to trigger the specific anti-tumor response. In the future, comparative studies between this modality and other therapies should be conducted for the treatment of lung cancer. In addition, more attention needs to be put on the immunomodulators that enhance the cryoimmunology.

In 1994, there were approximately 160,000 new cases of colon cancer in the United States with 58,000 fatalities, making this form of cancer the second most common cause of cancer deaths. Up to 50% of colon cancers may have a strong inherited factor, but in the remaining cases, diet and lifestyle factors are thought to play essential roles in the carcinogenic process. Various epidemiologic studies have examined the relation between obesity and colon cancer. The largest prospective study of 750,000 men showed that mortality from colorectal cancer was significantly elevated in men who were > or = 40% overweight. No such increase was found in women. Subsequent studies reported conflicting results. Overweight is likely a surrogate. Other risk factors include a high-fat, energy-dense diet; inadequate consumption of fruit and vegetables; and lack of physical activity, which have been associated with a high incidence of colon cancer.

The emergence of ChatGPT, a generative artificial intelligence tool, has sparked a revolution in the finance industry, enabling individuals to interact with technology in natural language. However, the use of ChatGPT in finance presents a profound array of ethical considerations that demand careful scrutiny to ensure its responsible and ethical use. After a concise exploration of ChatGPT's applications in finance, this policy article delves into the ethical challenges arising from the use of ChatGPT in finance, including outcomes contaminated with biases, incorporation of fake information in the financial decisions, concerns surrounding privacy and security, lack of transparency and accountability in the decision-making processes and financial services, human job displacement, and the intricate web of legal complexities. Our article asserts that financial institutions employing ChatGPT must proactively devise strategies to confront these burgeoning challenges, mitigating their adverse effects on both individuals and society as a whole. Additionally, we propose relevant policies to tackle these ethical quandaries head-on. In essence, this article illuminates the imperative need for a meticulous ethical framework, facilitating an informed and responsible use of ChatGPT in the realm of finance, safeguarding the welfare of individuals and society. While our work significantly contributes to the research and practice of finance, we also identify future research avenues.

Lung cancer is the leading cause of cancer deaths, yet research funding is by far the lowest for lung cancer than for any other cancer compared with respective death rates. Although this discrepancy should appear alarming, one could argue that lung cancer deserves less attention because it is more attributable to poor life choices than other common cancers. Accordingly, the general question that I ask in this article is whether victims of more avoidable diseases, such as lung cancer, deserve to have their needs taken into less consideration than those of less avoidable diseases, on the grounds of either retributive or distributive justice. Such unequal treatment may be the "penalty" one incurs for negligent or reckless behavior. However, I hope to show that such unequal treatment cannot be supported by any coherent accounts of retributive or distributive justice.

Colorectal cancer (CRC) is the one of the leading causes of cancer-related deaths in the world. CRC is responsible for more than 600,000 deaths annually and incidence rates are increasing in most of the developing countries. Epidemiological and laboratory investigations suggest that environmental factors such as western style dietary habits, tobacco-smoking, and lack of physical activities are considered as risks for CRC. Molecular pathobiology of CRC implicates pro-inflammatory conditions to promote the tumor malignant progression, invasion, and metastasis. It is well known that patients with inflammatory bowel disease are at higher risk of CRC. Many evidences exist reiterating the link between Inflammation and CRC. Inflammation involves interaction between various immune cells, inflammatory cells, chemokines, cytokines, and pro-inflammatory mediators, such as cyclooxygenase (COX) and lipoxygenase (LOX) pathways, which may lead to signaling towards, tumor cell proliferation, growth, and invasion. Thus, this review will focus on mechanisms by which pro-inflammatory mediators and reactive oxygen/nitrogen species play a role in promoting CRC. Based on these mechanisms, various preventive strategies, involving anti-inflammatory agents, such as COX inhibitors, COX-LOX inhibitors, iNOS inhibitors, natural supplements/agents, and synthetic agents, that blocks the inflammatory pathways and suppress CRC are discussed in this review.

Cybersecurity issues and their impact on compliance with the Health Insurance Portability and Accountability Act (HIPAA) and the Health Information Technology for Economic and Clinical Health (HITECH) Act are becoming more of an enforcement focus for a variety of government agencies, including the US Department of Health and Human Services, the Federal Trade Commission, and the Department of Justice. In the case presented in this article, a nurse in a neurology practice opted to speak with a patient about human immunodeficiency virus testing procedures in a manner audible to others in the waiting room. Computer screens with patient information were visible to anyone approaching a desk, the staff had not been trained on cybersecurity issues, and malware infected the computers used in the practice. In light of these circumstances and the launch of Phase 2 of the HIPAA Audit Program by the US Department of Health and Human Services Office for Civil Rights, the neurology practice must consider the following questions. First, could the gaps in the technical, administrative, and physical requirements of HIPAA and the HITECH Act result in an adverse audit and penalties? Second, what course of action does the law mandate in response to a ransomware attack?

In spite of improvements in care of colon cancer patients, prevention may enable potential patients to avoid cancer therapy. Although screening is direct and effective, dietary modification or low-risk chemopreventive agents might prevent colon cancer development. In this article, we review recent developments in colon cancer prevention, emphasizing nutrition.
