Human Papillomavirus (HPV) associated with oropharyngeal and oral squamous cell carcinoma (OPSCC and OSCC) is escalating over the years. Hence, the present review aims to determine the prevalence of HPV-OSCC and HPV-OPSCC in Asian countries over the last decades. An electronic search was conducted using nine online databases to identify English-language articles on the prevalence of HPV-OPSCC and HPV-OSCC in Asian countries from January 2011 to June 2022. The risk of bias was assessed using the JBI critical appraisal checklist and the level of evidence was determined based on the OCEBM guideline. Single-arm meta-analysis was used to estimate the weighted mean prevalence of HPV-OPSCC and HPV-OSCC among patients in Asia. Subgroup analysis meta-regression and Egger’s tests were also conducted. 59 eligible studies were included with a higher prevalence of HPV-OPSCC (32.6%-37.4%) as compared to HPV-OSCC (10.9%-23.5%). Subgroup analysis revealed that the weighted mean prevalence of HPV-OPSCC was significantly higher (P<0.001) among East Asians, while the weighted mean prevalence of HPV-OSCC was significantly higher (P<0.001) among South Asians. All studies showed a low to moderate risk of bias with the level of evidence ranked between 2 and 3. The diagnostic tools utilised and geographical locations significantly affect the findings.

Denture stomatitis is a common inflammation of the palatal mucosa beneath removable dentures. The objective of this article was to examine the systematic reviews and clinical trials pertaining to the treatment of denture stomatitis. For this research, electronic databases (PubMed, Embase, Scopus, and ISI Web of Science) were searched from January 2000 to June 2021 using specified MESH keywords. Irrelevant articles were eliminated in three steps based on their titles, abstracts, and body texts. In the final analysis, 47 papers were selected, which included 12 systematic reviews and 35 clinical trials. Herbal compounds and denture disinfection were the interventions most commonly indicated. We concluded that, possibly due to the complex nature of this lesion’s etiology, there is no present definitive therapy guideline for this prevalent lesion.

Sleep disorders can be the result of psychiatric or neurological conditions, such as post-traumatic stress disorders, depression, anxiety, Alzheimer’s disease, Parkinson’s disease. At the same time, changes in sleep, known as sleep disorders, are closely related to various metabolic dysfunctions, which in turn are the result of the generation of reactive oxygen species, or otherwise known as oxidative stress. For this reason, cannabinoid derivatives are increasingly used for this purpose. Among the most used are delta-9 tetrahydrocannabinol (THC) and cannabidiol (CBD). These agents interact with the endogenous endocannabinoid system, either by direct action on specific receptors, or by increasing the availability of endocannabinoids, modifying particular mental states (anxiety, depression). The results of the studies specified in this article provide promising evidence regarding the positive effects of CBD, which extend beyond the scope of sleep disorders, with possible applications also in the case of the accumulation of reactive oxygen species.

In this review we discuss the adrenergic pathways for alpha 1 and alpha 2 receptors and the current as well as potential future medication targeting these receptors. Overall, there is ongoing research into a multitude of directions with a promising outlook for alpha 1 and alpha 2 adrenergic receptors. The alpha 1-adrenergic receptor subfamily is currently modulating only a modest number of nervous system functions due the fact, that only a relatively small number of selective commercial products are available. Chronic stress can affect the long-term depression of alpha 1 receptors. Recent studies are searching for new molecular targets which might act on these receptors. Presynaptic alpha 2 receptors play an important role in modulating release of several neurotransmitters in the central nervous system. The future of alpha 2 adrenergic receptors in clinical practice looks even more promising and versatile than that of alpha 1 adrenergic receptors. Alpha 2 adrenergic receptors show different responses, especially regarding hypertension and heart failure treatment, and current research suggests a genetic component as a cause, which is being explored further.

Implant therapy is a commonly based method of replacing missing teeth. A range of physical, chemical, and biological modifications have been applied to the surface of titanium implants to improve their biological performance and osseointegration outcomes. Implant surface characteristics play an important function in several peri-implant cellular and molecular mechanisms. Clinicians are commonly placing dental implants with various surface roughness and modifications including plasma-sprayed, acid-etched, blasted, oxidized, hydroxyapatite-coated, or combinations of these procedures. Surface modifications are to facilitate early osseointegration and to ensure a long-term bone-to-implant contact without substantial marginal bone loss can be accomplished. It is apparent that different modifications have a range of beneficial effects, it is essential to consider at what time point and in what conditions these effects occur. This article reviews existing surface modification technologies of mainstream dental implants and the correlation between implant surface coatings and their performance of osseointegration or anti-bacterial ability it needs to be evaluated.

Bronchopulmonary cancer represents the neoplasms associated with the highest mortality rate, despite diagnostic and therapeutic advances in recent decades. Early diagnosis is often difficult due to the paucity of symptoms or superinfections. Screening subjects at risk of developing lung cancer include clinical, bacteriological, inflammatory status, and genetic profile assessment. The personal microbiome has an essential role in the physiology of the human body. The gut-lung axis plays an essential role in carcinogenesis, being involved in various pathways. The lung microbiome can contribute to the development of lung cancer either directly by acting on tumor cells or indirectly by modulating the tumor-associated immune response. The gut microbiome can directly affect the response to immunotherapy in patients with non-small cell lung cancer.

Insulin resistance is a heterogenous condition with high prevalence in medical practice. As diabesity reaches epidemic levels worldwide, the role of insulin resistance is getting great importance. Contribution of risk factors like sedentary lifestyle, diets high in saturated fats and refined carbohydrates leads to this state with significant consequences. Besides its role in diabetes, insulin resistance is also associated with other several endocrine diseases, having not only a role in their development, but also to their treatment approach, evolution and even prognosis. The present review summarizes the current literature on the clinical significance of insulin resistance, as well as the possible underlying mechanisms and treatment options in order to achieve a high quality of life of these categories of patients. Deepening the role of inflammatory cytokines involved in insulin resistance paves the way for future research findings in this continuously evolving field.

Multiple sclerosis is an unpredictable neurologic disease affecting 2.8 million people worldwide. Individuals with MS experience multiple physical and psychological symptoms such as depression, anxiety, fatigue, and pain that impact their general functioning and quality of life. The aim of this review is to highlight the importance of psychological interventions in reducing depression and anxiety symptoms associated with the diagnosis of multiple sclerosis. Cognitive and behavioral techniques are also useful in relieving the specific symptoms of multiple sclerosis. However, few studies have captured the psychological processes involved in reducing the symptoms of depression and anxiety, which is why greater concern is recommended in future studies in order to develop better psychological interventions tailored for patients with multiple sclerosis.

Although the term of amyotrophic lateral sclerosis (ALS) is often used interchangeably with motor neuron disease, ALS is universally accepted as a multisystem disorder. Cognitive impairment is an acknowledged feature of ALS, affecting language, memory and behaviour, and apathy is considered to be the prevalent behavioural alteration in ALS. It can be divided in three subtypes: executive, emotional and initiation apathy. Out of the three subtypes, initiation apathy is common among patients with ALS. Even in patients that do not meet the criteria for ALS with frontotemporal dementia, low-key neuropsychiatric and cognitive changes can be observed. Apathy has also been found to be systematically associated with disruptions in medial frontal cortex and subcortical structures in several neuroimaging studies that confirm the pre-existing brain lesions in the early stages of this disease. Thus, there is a growing body of evidence that motor signs and symptoms are accompanied or even preceded by cognitive and behavioural alterations, and screening for non-motor signs and symptoms can be clinically relevant.

Soy polysaccharides represent a multipurpose class of chemicals that include both therapeutical and technological properties. Since they have been first time introduced in the pharmaceutical field, Soy polysaccharides were used in two different pharmaceutical formulations; sublingual tablets and in colon drug delivery. For the sublingual tablets, Soy polysaccharides under the brand name of Emcosoy© – were used as a superdisintegrant in concentrations between 4-8% showing comparable results with the artificial superdisintegrants (sodium starch glycolate, sodium croscarmellose, and polyvinylpyrrolidone). The second technological field where Soy polysaccharides were used is represented by colon drug delivery where it was used in combination with ethylcellulose showing a prolonged lag time compared to the results found in the literature. The medicinal effect of these polysaccharides consists of treating diarrhea. As it will be presented in the article, these chemical compounds tend to decrease the aqueous stool time in patients with diarrhea and to conduct to a softer stool in healthy patients. In conclusion, these polysaccharides present multiple purposes possessing a medicinal effect and also the possibility of being used as a double-faceted pharmaceutical excipient.
