RESUMEN

This study assessed the likelihood of referral for liver transplantation assessment in a prospective cohort of patients co-infected with HIV and hepatitis B or C with complications of cirrhosis. There were 141 co-infected patients from 11 UK centres with at least one complication of cirrhosis recorded (either decompensation or hepatocellular carcinoma) out of 772 identified with cirrhosis and/or HCC. Only 23 of these 141 (16.3%) were referred for liver transplantation assessment, even though referral is recommended for co-infected patients after the first decompensation episode.

RESUMEN

Hepatocellular carcinoma (HCC) is now the third leading cause of cancer deathsworldwide and is generally presented at an advanced stage, limiting patients' quality of life. The conventional cytotoxic systemic therapy has proved to be ineffective in HCC, since its induction several decades ago. Today it is possible to use our knowledge of molecular hepatocarcinogenesis to provide a targeted therapy. Sorafenib has demonstrated large improvements in overall survival in HCC. This review describes the molecular mechanisms and potential therapeutic targets, focusing on sorafenib, sunitinib, tivantinib, antiangiogenic agents, and current and future immunotherapies. Thus, it will be necessary in the future to classify HCCs into subgroups according to their genomic and proteomic profiling. The identification of key molecules/receptors/signaling pathways and the assessment of their relevance as potential targets will be the main future challenge potentially influencing response to therapy. Defining molecular targeted agents that are effective for a specific HCC subgroup will hopefully lead to personalized therapy.

RESUMEN

BACKGROUND: Tobacco use is a global pandemic, affecting an estimated 1.2 billion people and resulting in substantial health burdens and associated costs. OBJECTIVES: The aim of this study was to estimate the efficacy of several treatments for smoking cessation in a real-life setting and to evaluate predictors of smoking abstinence. METHODS: This research was designed with a sample of 593 cases recorded over the period between 2015 and 2016. Six treatment groups were included: (1) bupropion and motivational interviewing (MI); (2) bupropion, nicotine replacement therapy (NRT), and MI; (3) NRT and MI; (4) varenicline and MI; (5) personal vaporizer electronic cigarette and MI; and (6) electronic cigarette, cigarette like "cigalike," and MI. RESULTS: Results support the efficacy of all treatment groups when used in a real-life setting. The predictors of smoking abstinence were sex, partner smoking status, previous quit attempts, daily consumption, self-efficacy, and level of nicotine dependence. CONCLUSIONS: The use of different therapeutic strategies in clinical practice, including pharmacotherapy and nonstandard electronic nicotine delivery systems, such as an electronic cigarette, ensures a greater chance of cessation success and the possibility of tailoring interventions according to patients' resources.

RESUMEN

The objective of our research was to compare the initial efficacy and acceptability, in this special population, of different motivational stimuli to improve motivation to quit smoking. We enrolled 40 young adult smokers, between their twenties and their thirties, not motivated to quit. Our study adopted a visual analog scale to assess the motivation to quit at first visit (baseline) and after three different types of stimuli: a packet of cigarettes containing shocking images; a brief film showing pulmonary effects of smoking; a virtual reality period based on the progression of smoking-related illnesses. We compared the motivation to quit smoking between the series of stimuli and between the stimuli and the baseline assessment. Compared with the first assessment, all stimuli were significant in improving the motivation for smoking cessation. There was a statistically significant modification between the packet of cigarettes and the movie. The difference between the packet of cigarettes containing shocking images and the virtual reality was significant. The difference between the film and the virtual reality was also highly significant. The application of virtual reality would appear to greatly increase the motivation to smoking cessation in young adult smokers not motivated to quit.

RESUMEN

Liver cirrhosis is a major cause of morbidity and mortality worldwide, mainly due to complications of portal hypertension. In this article, we review the current understanding on the pathophysiology, the diagnostic criteria and the available therapeutic options for patients with emerging hepatic syndromes in cirrhosis, namely the hepatorenal, hepato-adrenal and hepatopulmonary syndrome. The hepatorenal syndrome is a well-recognized complication of advanced cirrhosis and is usually associated with an accelerated course to death unless liver transplantation is performed. The hepatopulmonary syndrome is often missed in the evaluation of patients with cirrhosis; however, early recognition is essential for the efficient management of individual patients. The hepato-adrenal syndrome, although not fully characterized, offers an exciting field for research and potential therapeutic interventions.

RESUMEN

The authors present a case of a man with recurrent syncopal episodes. The patient had been hospitalized twice before reaching a correct diagnosis. The syncope was originally ascribed to a sick sinus syndrome, which led to pacemaker implantation. Nonetheless, the patient relapsed with no evidence of pacemaker dysfunction, and was readmitted to the hospital where the likely cause for his symptoms was identified: an adenocarcinoma of the lung infiltrating the vagus and recurrent laryngeal nerves. No further syncopal episodes occurred after thoracic surgery. This syncope led to an early diagnosis of lung cancer leading to appropriate and life extending treatment.

RESUMEN

Over the last years it has started a real revolution in the treatment of chronic hepatitis C. This occurred for the availability of direct-acting antiviral agents that allow to reach sustained virologic response in approximately 90% of cases. In the near future further progress will be achieved with the use of pan-genotypic drugs with high efficacy but without side effects.

RESUMEN

BACKGROUND: Hepatocellular carcinoma is a major health problem worldwide and the third most common cause of cancer-related death. HCC treatment decisions are complex and dependent upon tumor staging. Several molecular targeted agents have been evaluated in clinical trials in advanced HCC. Despite of only modest objective response rates according to the Response Evaluation Criteria in Solid Tumors, several studies showed encouraging results in terms of prolongation of the time to progression, disease stabilization, and survival. Cellular immunotherapy would improve the immune state and has potential in enhancing the therapeutic outcome for HCC patients. MATERIALS AND METHODS: A search of the literature was made using cancer literature, the PubMed, Scopus, and Web of Science (WOS) database for the following keywords: "hepatocellular carcinoma," "molecular hepatocarcinogenesis," "targeted therapy," "molecular immunological targets," "tumour-associated antigens," "Tregs," "MDSCs," "immunotherapy." DISCUSSION AND CONCLUSION: Treatment strategies combining blockade of immunoregulatory cell types such as Tregs and MDSCs and of inhibitory receptors, with vaccine-induced activation of TAA-specific T cells, may be necessary to achieve the most effective therapeutic antitumour activity in HCC. In the future, new therapeutic options will be represented by a blend of immunotherapy-like vaccines and T-cell modulators, supplemented by molecularly targeted inhibitors of tumor signaling pathways.

RESUMEN

BACKGROUND: Hepatocellular carcinoma is one of the most common and lethal malignant tumors worldwide. Over the past 15 years, the incidence of HCC has more than doubled. Due to late diagnosis and/or advanced underlying liver cirrhosis, only limited treatment options with marginal clinical benefit are available in up to 70% of patients. During the last decades, no effective conventional cytotoxic systemic therapy was available contributing to the dismal prognosis in patients with HCC. A better knowledge of molecular hepatocarcinogenesis provides today the opportunity for targeted therapy. MATERIALS AND METHODS: A search of the literature was made using cancer literature, the PubMed, Scopus, and Web of Science (WOS) database for the following keywords: "hepatocellular carcinoma," "molecular hepatocarcinogenesis," "targeted therapy," and "immunotherapy." DISCUSSION AND CONCLUSION: Treatment decisions are complex and dependent upon tumor staging, presence of portal hypertension, and the underlying degree of liver dysfunction. The knowledge of molecular hepatocarcinogenesis broadened the horizon for patients with advanced HCC. During the last years, several molecular targeted agents have been evaluated in clinical trials in advanced HCC. In the future, new therapeutic options will be represented by a blend of immunotherapy-like vaccines and T-cell modulators, supplemented by molecularly targeted inhibitors of tumor signaling pathways.

RESUMEN

BACKGROUND: Benign liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In fact, in most cases, benign liver tumors are not diagnosed because patients are asymptomatic. When they are detected, it's usually because the person has had medical imaging tests, such as an ultrasound (US), computed tomography (CT) scan, or magnetic resonance imaging (MRI), for another condition. MATERIALS AND METHODS: A search of the literature was made using cancer literature and the PubMed, Scopus, and Web of Science (WOS) database for the following keywords: "hepatic benign tumors", "hepatic cystic tumors", "polycystic liver disease", "liver macroregenerative nodules", "hepatic mesenchymal hamartoma", "hepatic angiomyolipoma", "biliary cystadenoma", and "nodular regenerative hyperplasia". DISCUSSION AND CONCLUSION: Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in some areas of the world; there is an increasing incidence worldwide. Approximately 750,000 new cases are reported per year. More than 75 % of cases occur in the Asia-Pacific region, largely in association with chronic hepatitis B virus (HBV) infection. The incidence of HCC is increasing in the USA and Europe because of the increased incidence of hepatitis C virus (HCV) infection. Unlike the liver HCC, benign tumors are less frequent. However, they represent a chapter always more interesting of liver disease. In fact, a careful differential diagnosis with the forms of malignant tumor is often required in such a way so as to direct the patient to the correct therapy. In conclusion, many of these tumors present with typical features in various imaging studies. On occasions, biopsies are required, and/or surgical removal is needed. In the majority of cases of benign hepatic tumors, no treatment is indicated. The main indication for treatment is the presence of significant clinical symptoms or suspicion of malignancy or fear of malignant transformation.

RESUMEN

INTRODUCTION: Patients with severe asthma have a significant unmet need with persistent symptoms and/or frequent exacerbations despite high intensity treatment. These severe unrelenting symptoms have a huge impact on heathcare resources due to frequent hospital admissions and requirement for intensive and expensive medications. There is a compelling need for more effective and safer therapies to help severe asthma sufferers to achieve adequate control of their disease. AREAS COVERED: Expanding knowledge of innate and adaptive immune responses has led to development of new biologic approaches for severe asthma. Here, the authors will review the existing efficacy and safety data from clinical trials of some of the new biologic therapies that are in development for severe asthma. Their specific role in distinctively targeted subpopulations of severe asthmatics will be also discussed. EXPERT OPINION: Defining and phenotyping severe asthma patients will become increasingly important as some patients who were previously classified as having severe asthma may become well-controlled with a targeted phenotype-specific treatment. However, pharmacoeconomic concerns should also be taken into account given the elevated acquisition costs of recombinant human monoclonals and of the diagnostic screening procedures for the identification of potential responders.

RESUMEN

Commonly abused drug are cocaine, marijuana, cigarettes, heroin, and alcohol. The review emphasizes the importance for clinicians to be alert to the possibility of this substance as a precipitating factor for acute asthma. Substance use disorders to characterize illnesses associated with drug use. The use of drugs of abuse increases risk of developing more severe symptoms, higher frequency of exacerbations and having and significant effect on care resources due to clinicians visits and frequent hospital admissions. Abused drug has been shown to accelerate the decline in lung function and to increase numbers of life-threatening asthma attacks, and greater asthma mortality.
