Extract of Laurus nobilis attenuates inflammation and epithelial ulcerations in an experimental model of inflammatory bowel disease
Authors: Robert A. Orlando, Natalie S. Correa
Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, are classified as chronic inflammatory disorders and typically require anti-inflammatory drug therapies, such as glucocorticoid regimens, non-steroidal anti-inflammatory drugs, and biologics, aimed at reducing inflammation in the bowel wall. However, each of these therapies is accompanied by a list of possible serious side effects. Because of this, there remains an urgent need to identify new pharmacologic options to reduce or prevent the pro-inflammatory events of IBD while minimizing adverse side effects, and to make available more cost-effective treatment modalities. We have previously identified several herbal extracts that demonstrate potent bio-inhibitory activity of the innate immune response. In particular, Laurus nobilis (LN), or more commonly called bay laurel, demonstrated significant anti-inflammatory function by inhibiting nuclear factor-κB activation. Based upon our original in vitro findings, we have now examined the effects of this herbal extract on a murine dextran sodium sulfate (DSS) model of IBD. Hematoxylin and eosin-stained paraffin sections prepared from DSS treated animals show clear epithelial damage, including ulcerations, extensive neutrophil infiltration into the mucosal layer, and granuloma formation. Tissue from DSS treated animals that also received LN extract showed improved tissue morphology more closely resembling that from control animals. In addition, DSS treated mice with co-administration of LN extract showed a significant reduction in CD4+ antibody staining within the mucosal layer in colonic sections indicating reduced lymphocyte infiltration. Based on these findings, we believe that administration of LN extracts may be effective in reducing the intestinal epithelial damage seen in human IBD and warrants further investigation through clinical trials.

Substance Use Disorder (SUD) is understood as the persistent use of substances to the detriment of the individual's livelihood and wellness. SUD can have serious mental, physical, and social ramifications if not properly addressed. Though SUD can develop at any age, it is especially important to address in adolescents, given rising prevalence of certain substances (e.g. cannabis) in that age group and poor prognosis associated with early-onset SUD. Data from the National Survey on Drug Use and Health show the lifetime use of illicit drugs in people ages 12-17 is 20.9%. The same survey found the rate of Substance Use Disorder in the past year for people ages 12-17 who used illicit drugs or alcohol to be 6.3% in 2020. [...]

Rabeprazole is a proton pump inhibitor that suppresses gastric acid production in the stomach. Available under different brand name products as well as in a variety of combination products, rabeprazole has several medical uses concerning the management of problems of pathological gastric acid. Rabeprazole's adverse effects tend to be mild but can be serious, including deficiencies in essential nutrients, rare incidences of liver damage, and immune-mediated reactions. As a class effect, rabeprazole can increase the risk for osteoporosis, serious infections (including Clostridium difficile infections), and kidney damage. Rabeprazole can theoretically contribute to numerous drug interactions, mediated both through its metabolic properties and its direct effect on acid in the stomach, though its potential for clinically meaningful drug interactions is low. Like other medications in the proton pump inhibitor class, rabeprazole's mechanism of action involves the irreversible inhibition of proton pumps in the stomach, which are responsible for gastric acid production. Rabeprazole has a number of chemical metabolites, though it is primarily degraded by non-enzymatic metabolism and excreted in the urine. Genetic differences in a person's drug-metabolizing enzymes may theoretically affect individual responses to rabeprazole therapy, though the clinical significance of this interaction is unlikely in comparison to other proton pump inhibitors. The purpose of this review is to provide an up-to-date monograph on rabeprazole.

The history of coronaviruses is an account of the discovery of coronaviruses and the diseases they cause. It starts with a report of a new type of upper-respiratory tract disease among chickens in North Dakota, US, in 1931. The causative agent was identified as a virus in 1933. By 1936, the disease and the virus were recognised as unique from other viral diseases. The virus became known as infectious bronchitis virus (IBV), but later officially renamed as Avian coronavirus. A new brain disease of mice (murine encephalomyelitis) was discovered in 1947 at Harvard Medical School in Boston. The virus was called JHM (after Harvard pathologist John Howard Mueller). Three years later a new mouse hepatitis was reported from the National Institute for Medical Research in London. The causative virus was identified as mouse hepatitis virus (MHV), later renamed Murine coronavirus. In 1961, a virus was obtained from a school boy in Epsom, England, who was suffering from common cold. The sample, designated B814, was confirmed as novel virus in 1965. New common cold viruses (assigned 229E) collected from medical students at the University of Chicago were also reported in 1966. Structural analyses of IBV, MHV, B18 and 229E using transmission electron microscopy revealed that they all belong to the same group of viruses. Making a crucial comparison in 1967, June Almeida and David Tyrrell invented the collective name coronavirus, as all those viruses were characterised by solar corona-like projections (called spikes) on their surfaces. Other coronaviruses have been discovered from pigs, dogs, cats, rodents, cows, horses, camels, Beluga whales, birds and bats. As of 2022, 52 species are described. Bats are found to be the richest source of different species of coronaviruses. All coronaviruses originated from a common ancestor about 293 million years ago. Zoonotic species such as Severe acute respiratory syndrome-related coronavirus (SARS-CoV), Middle East respiratory syndrome-related coronavirus (MERS-CoV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a variant of SARS-CoV, emerged during the past two decades and caused the first pandemics of the 21st century.

This review article is written to give a comprehensive and yet straightforward overview regarding a tropical disease named melioidosis. Besides that, this article also aims to promote awareness and research in the disease. Melioidosis is an infectious disease that ravages the tropical regions around the world. However, the awareness of this disease is lacking in developing countries. It is not even included in the WHO list of Neglected Tropical Disease. The ability of this disease to spread through air by inhalation makes it a potential agent for bioweapons, although there is no documented evidence of its use in biological warfare. There are also various gaps of research in melioidosis. A search into PubMed and Google Scholar was done by using keywords "melioidosis", "melioidosis biological agent", "Burkholderia pseudomallei", "human melioidosis", and "melioidosis review" while writing this review. Allocation of resources into the study and prevention of melioidosis will help to improve the disease burden in developing countries.

This article aims to provide a comprehensive overview of the infectious zoonotic disease Leptospirosis in tropical countries. Warm blooded animals such as mice, dogs, and cows can be infected by this disease and carry the disease to humans. Although cold blooded animals such as reptiles may have Leptospira bacteria in them, their role in causing diseases in humans are unknown. Once infected, symptoms can range from mild disease to life-threatening ones. The pathogenesis of the leptospirosis infection is not completely understood. Therefore, more researches are required to understand the disease. Searches into PubMed and Google Scholar were done by using keywords "leptospirosis", "human leptospirosis", "animal leptospirosis", "Leptospira", and "leptospirosis review" while writing this article. In conclusion, leptospirosis is a common disease in the tropics and the public should know the effective ways of avoiding or treating the disease.

Phage therapy refers to the use of bacteriophages (phages - bacterial viruses) as therapeutic agents against infectious bacterial diseases. This therapeutic approach emerged in the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the second world war. More recently however, the alarming rise of multidrug-resistant bacteria and the consequent need for antibiotic alternatives has renewed interest in phages as antimicrobial agents. Several scientific, technological and regulatory advances have supported the credibility of a second revolution in phage therapy. Nevertheless, phage therapy still faces many challenges that include: i) the need to increase phage collections from reference phage banks; ii) the development of efficient phage screening methods for the fast identification of the therapeutic phage(s); iii) the establishment of efficient phage therapy strategies to tackle infectious biofilms; iv) the validation of feasible phage production protocols that assure quality and safety of phage preparations; and (v) the guarantee of stability of phage preparations during manufacturing, storage and transport. Moreover, current maladapted regulatory structures represent a significant hurdle for potential commercialization of phage therapeutics. This article describes the past and current status of phage therapy and presents the most recent advances in this domain.

The history of penicillin was shaped by the contributions of numerous scientists. The ultimate result was the discovery of the mould Penicillium's antibacterial activity and the subsequent development of penicillins, the most widely used antibiotics. Following an accidental discovery of the mould, later identified as Penicillium rubens, as the source of the antibacterial principle (1928) and the production of a pure compound (1942), penicillin became the first naturally derived antibiotic. There is anecdotal evidence of ancient societies using moulds to treat infections and of awareness that various moulds inhibited bacterial growth. However, it is not clear if Penicillium species were the species traditionally used or if the antimicrobial substances produced were penicillin. In 1928, Alexander Fleming was the first to discover the antibacterial substance secreted by the Penicillium mould and concentrate the active substance involved, giving it the name penicillin. His success in treating Harry Lambert's streptococcal meningitis, an infection until then fatal, proved to be a critical moment in the medical use of penicillin. Many later scientists were involved in the stabilisation and mass production of penicillin and in the search for more productive strains of Penicillium. Among the most important were Ernst Chain and Howard Florey, who shared with Fleming the 1945 Nobel Prize in Physiology or Medicine.

Bilateral persistent sciatic artery (PSA) is a rare vascular anomaly. We report an exceptionally rare case of complete bilateral PSAs, diagnosed on computed tomography angiography (CTA) in a patient who sustained a gunshot wound to the lower limb. Incidental PSAs are unlikely to have clinical significance, however, the unusual anatomy and higher incidence of complications requires accurate reporting of such variants. In this case, the anomaly paradoxically proved beneficial given the proximity of the gunshot wound to the femoral vessels. The embryology, clinical and imaging findings, potential complications, and treatment options regarding PSA are discussed.
Does the packaging of health information affect the assessment of its reliability? A randomized controlled trial protocol
Authors: Denise Smith, James Heilman, Leela Raj
Background: Wikipedia is frequently used as a source of health information. However, the quality of its content varies widely across articles. The DISCERN tool is a brief questionnaire developed in 1996 by the Division of Public Health and Primary Health Care of the Institute of Health Sciences of the University of Oxford. They claim it provides users with a valid and reliable way of assessing the quality of written information. However, the DISCERN instrument’s reliability in measuring the quality of online health information, particularly whether or not its scores are affected by reader biases about specific publication sources, has not yet been explored.

Systematic reviews are a type of review that uses repeatable analytical methods to collect secondary data and analyse it. Systematic reviews are a type of evidence synthesis which formulate research questions that are broad or narrow in scope, and identify and synthesize data that directly relate to the systematic review question. While some people might associate ‘systematic review’ with 'meta-analysis', there are multiple kinds of review which can be defined as ‘systematic’ which do not involve a meta-analysis. Some systematic reviews critically appraise research studies, and synthesize findings qualitatively or quantitatively. Systematic reviews are often designed to provide an exhaustive summary of current evidence relevant to a research question. For example, systematic reviews of randomized controlled trials are an important way of informing evidence-based medicine, and a review of existing studies is often quicker and cheaper than embarking on a new study.

Beyond public health and economic costs, the COVID-19 pandemic adds strain, disrupts daily routines, and complicates mental health and medical service delivery for those with mental health and medical conditions. Bipolar disorder can increase vulnerability to infection; it can also enhance stress, complicate treatment, and heighten interpersonal stigma. Yet there are successes when people proactively improve social connections, prioritize self-care, and learn to effectively use mobile and telehealth.
Emotional and Psychological Impact of Interpreting for Clients with Traumatic Histories on interpreters: a review of qualitative articles
Authors: Salma Rehman, Parveen Ali, Aasia Rajpoot
Interpreters play an important role in the health and social care system. The aim of this review is to synthesize available qualitative studies exploring experiences of interpreters when working with individuals and groups who have experienced domestic violence and abuse or other traumatic situations. A comprehensive literature search of databases helped identify 18 studies including 3 quantitative and 15 qualitative studies published between 2003-2017. The studies were conducted in various countries and data analysis resulted in the development of 5 themes which included: ‘role and impact of interpreter’; ‘psychological and emotional impact of interpreting’; ‘workplace challenges faced by interpreters’; ‘coping strategies used by interpreters’; and ‘interpreters’ support needs’. Themes are discussed in relation to the available literature and gaps in the literature are identified.

Hepatitis D is a globally occurring liver disease. It afflicts those who have been infected by both the Hepatitis B virus (HBV) and also the Hepatitis D virus (HDV), since HDV needs the hepatitis B surface antigen (HBsAg) to replicate. It is therefore most prevalent in countries where HBV infection is also common, currently the Amazon basin and low income regions of Asia and Africa. Improved measures to control HBV in industrialised countries (such as by vaccination) have also reduced the prevalence of HDV, with the main remaining at-risk populations in those countries being injection drug users and immigrants from endemic HDV areas.
