Lung cancer remains a major factor contributing to morbidity and mortality worldwide. cannabidiol (CBD) and Δ9-tetrahydrocannabinol could serve as a specific treatment for lung cancer, owing to their essential role in lung cancer cell apoptosis. This review evaluated the antitumorigenic mechanisms of CBD in lung cancer cells.

Background: The biomarker soluble urokinase plasminogen activator receptor (suPAR) is an indicator of inflammation which is increased in a variety of chronic and acute disease states. Its most promising application in the emergency setting is to aid in the prognostic stratification of patients by identifying those at high risk of deterioration. This is a narrative review of studies evaluating the use of suPAR.

Sepsis is a condition characterized by high morbidity and mortality which is commonly encountered in an emergency and critical care setting. Despite a substantial body of research, the ideal biomarker for the diagnosis and prognostic stratification of septic patients remains unknown. This review aimed to summarize the publications referring to the validity of the biomarker presepsin when used for the detection, monitoring and prognosis in patients suffering with sepsis.

This review summarizes the published literature referring to the use and validity of the biomarker soluble urokinase plasminogen activator receptor (suPAR) when used for the assessment of patients with cardiac diseases. It is measured by enzyme-linked immunosorbent assay (ELISA) in plasma samples. In cardiology a cut-off value range of 3.

Introduction: The use of peripherally inserted central catheter (PICC) lines offers several advantages compared to traditional central venous catheters (CVCs) as the insertion procedure is minimally invasive, they may be retained safely for longer periods of time, and their use is associated with fewer catheter-related infections. Their use in patients suffering from a malignant disease is common but may pose a greater risk of complications due to the severe immunosuppression associated with treatment. This study was conducted to evaluate the safety of PICC lines in this group.

The adverse events of antiviral drugs are dose-dependent and often reversible. The nervous system is often affected and to date, many studies have been published regarding the central nervous system toxicity of antiviral agents. They may cause significant neuropsychiatric complications, which range from mild symptoms such as irritability and difficulty sleeping to severe complications such as depression, psychosis, and painful peripheral neuropathy, side effects which may necessitate discontinuation of treatment.

Introduction: Since December 2019, an outbreak of coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome - Coronavirus 2 (SARS-CoV-2) emerged in China and has become a global threat. Comparison of hematological parameters between mild and severe cases of SARS-CoV 2 is so far limited, but significant differences in parameters such as interleukin-6, d-dimers, glucose, fibrinogen and C-reactive protein have been already reported.

Purpose: In this study we analyzed the changes observed in easily measured blood biomarkers in the patients and provided evidence of how these markers can be used as prognostic factors of the disease.

Even though the early reports from China provided advance warning of what was to come, the COVID-19 pandemic has spread throughout the world with devastating consequences. Emergency measures are being implemented to reduce the magnitude of the public health crisis, prevent healthcare facilities from becoming overwhelmed and reduce the death toll of the disease. Containment strategies to mitigate viral transmission and emergency measures to increase the capacity of each country to provide intensive care are at the forefront of the public health management of the epidemic, even though the detrimental social and psychological effects of quarantine are evident on a global scale.

Severe COVID-19 illness is characterised by the development of Acute Respiratory Distress Syndrome (ARDS), for which the mainstay of treatment is represented by mechanical ventilation. Mortality associated with ARDS due to other causes is in the range of 40-60%, but currently available data are not yet sufficient to draw safe conclusions on the prognosis of COVID-19 patients who require mechanical ventilation. Based on data from cohorts of the related coronavirus-associated illnesses, that is to say Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS), prognosis would seem to be worse than ARDS due to other causes such as trauma and other infections.

Acute agitation is a common presenting symptom in the emergency ward and is also dealt with on a routine basis in psychiatry. Usually a symptom of an underlying mental illness, it is considered urgent and immediate treatment is indicated. The practice of treating agitation on an acute care basis is also referred to as rapid tranquilization.

Mental health issues such as depression and anxiety are common comorbidities of individuals suffering from chronic obstructive pulmonary disease (COPD), though they are frequently underdiagnosed and consequently undertreated. To that end we sought to identify the impact of co-morbid anxiety and depression in COPD patients and evaluate recent evidence regarding the management of such cases. A Pubmed search was conducted for relevant original articles with emphasis on the past 5 years.

Both periodontitis and chronic obstructive pulmonary disease (COPD) are among the most common diseases associated with smoking. These conditions frequently present alongside comorbidities including diabetes, coronary heart disease, duodenal ulcer, deep vein thrombosis, pulmonary embolism, osteoporosis and muscle atrophy. Chronic inflammation contributes to the pathology of both periodontitis and COPD, and in patients suffering from both conditions treatment of periodontitis may lead to relief from COPD symptoms as well.

The disease burden associated with schizophrenia and bipolar disorder is substantial, with affected individuals having a shorter life expectancy and a high risk of severe physical comorbid conditions. These individuals are more likely to smoke and have a longer smoking history compared to the general population. Furthermore, use of antipsychotic drugs has also been linked to active smoking.

Purpose: A systematic review and meta-analysis of all relevant randomized controlled trials was conducted to evaluate the safety and efficacy of vilazodone in the acute treatment of generalized anxiety disorder (GAD).

Methods: The literature was searched through all relevant databases in order to identify clinical trials on the use of vilazodone in the treatment of GAD. Once the trials were identified, data was extracted and analyzed using Revman5.

Antimicrobial drugs used in clinical practice are selected on the basis of their selective toxicity against bacterial cells. However, all exhibit multiple offsite interactions with eukaryotic cell structures, resulting in adverse reactions during antimicrobial pharmacotherapy. A multitude of these side effects involve the nervous system as antimicrobials at clinically relevant concentrations seem to interact with many of the same molecules usually implicated in the action of psychotropic drugs.

The 5-HT7R is the most recently cloned serotonin receptor and thus one the least studied. Many drugs, experimental and in clinical use bind to 5-HT7 with high affinity, though their effects have yet to be clearly elucidated. Its physiological function, though not completely clear, is mostly associated with learning and memory, with both agonists and antagonists possessing subtle procognitive and promnesic properties.
