Hepatocellular carcinoma (HCC) is a prime public health concern that accounts for most of the primary liver malignancies in humans. The most common etiological factor of HCC is hepatitis B virus (HBV). Despite recent advances in treatment strategies, there has been little success in improving the survival of HCC patients. To develop a novel therapeutic approach, evaluation of a working hypothesis based on different viewpoints might be important. Long interspersed element 1 (L1) retrotransposons have been suggested to play a role in HCC. However, the molecular machineries that can modulate L1 biology in HBV-related HCC have not been well-evaluated. Here, we summarize the profiles of expression and/or activation status of L1-related genes in HBV-related HCC, and HBV- and HCC-related genes that may impact L1-mediated tumorigenesis. L1 restriction factors appear to be suppressed by HBV infection. Since some of the L1 restriction factors also limit HBV, these factors may be exhausted in HBV-infected cells, which causes de-suppression of L1. Several HBV- and HCC-related genes that interact with L1 can affect oncogenic processes. Thus, L1 may be a novel prime therapeutic target for HBV-related HCC. Studies in this area will provide insights into HCC and other types of cancers.

Melanoma is a major public health concern that is responsible for significant morbidity and mortality, particularly in countries such as New Zealand and Australia where it is the commonest cause of cancer death in young adults. Until recently, there were no effective drug therapies for patients with advanced melanoma however significant advances in our understanding of the biological and molecular basis of melanoma in recent decades have led to the development of revolutionary treatments, including targeted molecular therapy and immunotherapy. This review summarizes our current understanding of the key events in the pathway of melanomagenesis and discusses the role of genomic analysis as a potential tool for improved diagnostic evaluation, prognostication and treatment strategies. Ultimately, it is hoped that a continued deeper understanding of the mechanisms of melanomagenesis will lead to the development of even more effective treatments that continue to provide better outcomes for patients with melanoma.

Introduction-Viral hepatitis is one of the major public health concern worldwide. Hepatitis B virus (HBV) and hepatitis C virus (HCV) are of great concern due to their association with cirrhosis and hepatocellular carcinoma. Aims & Objectives-i)To determine the frequency of Hepatitis B surface antigen and anti-HCV antibodies in patients coming to a tertiary care teaching hospital ii)To estimate the occurrence of co-infection with hepatitis B virus and hepatitis C virus iii) To analyse the risk factors associated with hepatitis B, hepatitis C and their co-infections. Method- This prospective study included serum samples which were subjected to detection of HBs antigen and anti-HCV antibodies using rapid immunochromatographic card tests, which were further confirmed by Enzyme Linked Immunosorbent Assay (ELISA). Results- Out of total of 12,502 cases, the seropositivity of HBs antigen and anti-HCV antibodies was found to be 3.6% (452 /12,502) and 6.1% (758 /12,502) respectively. The frequency of co-infection (HBs antigen and anti-HCV antibodies) was found to be 0.8% (99 /12,502). Male to female ratio for hepatitis B, hepatitis C and co-infection was 2.1:1, 1.6:1and 2.3:1, respectively. The commonest risk factor associated with seropositivity of HBV was intravenous drug use, followed by blood / blood components transfusion. Hepatitis C infection was most commonly seen with blood / blood components transfusion, followed by intravenous drug use. Conclusions: Counseling and health education regarding the safe injection practices, safe sexual practices , screening of blood / blood products and vaccination against HBV are the essential steps to combat viral hepatitis.

Tumour Initiation

Hepatocellular carcinoma (HCC) is a major public health concern and one of the leading causes of tumour-related deaths worldwide. Extensive evidence endorses that HCC is a multifactorial disease characterised by hepatic cirrhosis mostly associated with chronic inflammation and hepatitis B/C viral infections. Interaction of viral products with the host cell machinery may lead to increased frequency of genetic and epigenetic aberrations that cause harmful alterations in gene transcription. This may provide a progressive selective advantage for neoplastic transformation of hepatocytes associated with phenotypic heterogeneity of intratumour HCC cells, thus posing even more challenges in HCC treatment development. Epigenetic aberrations involving DNA methylation, histone modifications, and noncoding miRNA dysregulation have been shown to be intimately linked with and play a critical role in tumour initiation, progression, and metastases. The current review focuses on the aberrant hepatoepigenetics events that play important roles in hepatocarcinogenesis and their utilities in the development of HCC therapy.

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related mortality worldwide. Host gene variants may influence hepatitis B virus- (HBV-) related HCC. Human leukocyte antigens (HLA) play an important role in presenting virus antigens to immune cells that are responsible for the clearance of virus-infected cells and tumor cells. Previous studies have investigated the HLA-DQ (rs2856718 and rs9275572) polymorphisms that may be associated with the development of HBV-related HCC. However, the results are controversial or inconclusive. Hence, we conducted a meta-analysis to derive a more precise estimation of the associations. A total of 6 articles were used to evaluate the effect of the two polymorphisms on the risk of HBV-related HCC. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. We found that rs2856718 and rs9275572 in HLA-DQ significantly decreased HBV-related HCC in total population, especially in Chinese, but not in Saudi Arabian. Further validation of our results in larger populations and different ethnicities are required.

ABSTRACT It is important for emergency physicians to be aware of new psychoactive agents being used as recreational drugs. “Bath salts,” which include 3,4-methylenedioxypyrovalerone (MDPV), mephedrone, and methylone, are the newest recreational stimulants to appear in Canada. There are currently more than 12 synthetic cathinones marketed as bath salts and used with increasing frequency recreationally. Although these drugs are now illegal in Canada, they are widely available online. We present a case report and discuss bath salts intoxication and its anticipated sympathomimetic toxidrome, treatment strategies, and toxicologic analysis, Treatment should not rely on laboratory confirmation. Since the laboratory identification of such drugs varies by institution and toxicologic assay, physicians should not misconstrue a negative toxicology screen as evidence of no exposure to synthetic cathinones. Illicit bath salts represent an increasing public health concern that involves risk to the user, prehospital personnel, and health care providers.

Coronaviruses (CoVs) are RNA viruses that have become a major public health concern since the Severe Acute Respiratory Syndrome-CoV (SARS-CoV) outbreak in 2002. The continuous evolution of coronaviruses was further highlighted with the emergence of the Middle East Respiratory Syndrome-CoV (MERS-CoV) outbreak in 2012. Currently, the world is concerned about the 2019 novel CoV (SARS-CoV-2) that was initially identified in the city of Wuhan, China in December 2019. Patients presented with severe viral pneumonia and respiratory illness. The number of cases has been mounting since then. As of late February 2020, tens of thousands of cases and several thousand deaths have been reported in China alone, in addition to thousands of cases in other countries. Although the fatality rate of SARS-CoV-2 is currently lower than SARS-CoV, the virus seems to be highly contagious based on the number of infected cases to date. In this review, we discuss structure, genome organization, entry of CoVs into target cells, and provide insights into past and present outbreaks. The future of human CoV outbreaks will not only depend on how the viruses will evolve, but will also depend on how we develop efficient prevention and treatment strategies to deal with this continuous threat.

Dementia is a major public health concern that afflicts an estimated 24.3 million people worldwide. Great strides are being made in order to better diagnose, prevent, and treat these disorders. Dementia is associated with multiple complications, some of which can be life-threatening, such as dysphagia. There is great variability between dementias in terms of when dysphagia and other swallowing disorders occur. In order to prepare the reader for the other articles in this publication discussing swallowing issues in depth, the authors of this article will provide a brief overview of the prevalence, risk factors, pathogenesis, clinical presentation, diagnosis, current treatment options, and implications for eating for the common forms of neurodegenerative dementias.

Fat Bodies

Over the last twenty years or so, fatness, pathologised as overweight and obesity, has been a core public health concern around which has grown a lucrative international weight loss industry. Referred to as a ‘time bomb’ and ‘the terror within’, analogies of ‘war’ circulate around obesity, framing fatness as enemy.2 Religious imagery and cultural and moral ideologies inform medical, popular and policy language with the ‘sins’ of ‘gluttony’ and ‘sloth’, evoked to frame fat people as immoral at worst and unknowledgeable victims at best, and understandings of fatness intersect with gender, class, age, sexuality, disability and race to make some fat bodies more problematically fat than others. As Evans and Colls argue, drawing on Michel Foucault, a combination of medical and moral knowledges produces the powerful ‘obesity truths’ through which fatness is framed as universally abject and pathological. Dominant and medicalised discourses of fatness (as obesity) leave little room for alternative understandings.
