The importance of oral care and its relationship with an individual's well-being has been identified over the past few decades. As there is a drastic increase in the aging population, so did the use of removable dentures more than ever before. The use of dentures among the elderly provides functional advantages and esthetic benefits. However, improper use and poor oral hygiene with removable dentures come with complications, including denture stomatitis, ulcerations, pneumonia, and many more. The study aims to determine the complications associated with inappropriate use and poor oral care and bring forth evidence-based dentistrecommended guidelines for denture maintenance.Articles were systematically screened in PubMed/Medline (Medical Literature Analysis and Retrieval System Online), PubMed Central (PMC), and Cochrane Library using keywords. Medical Subject Heading (MeSH) was also utilized to identify relevant articles. Inclusion and exclusion criteria were applied, duplicate articles were discarded, and then the articles were reviewed by title and abstract screening. The remaining articles went through a detailed full-text review. A quality appraisal check was conducted for each unique type of research publication, after which a total of 22 articles were finalized.In this study, we have seen pathological biofilm formation on dentures, life-threatening pneumonia, denture stomatitis, and accidental ingestion/aspiration of dentures amongst the elderly population. The study also identified members with low literacy rates, minorities, and low-income families seem to be at higher risk of poor oral care and denture hygiene. We identified that most of these complications could be prevented with proper guidance and education. In the future, a further detailed study is important as no clear consensus exists in terms of best practices of denture cleaning methods. In addition, measures should be initiated to encourage regular dentist appointments and increase accessibility among members of low socioeconomic status and minorities.
Metformin, a biguanide hypoglycemic agent that is safe and effective for treating acne in women with the polycystic ovarian syndrome (PCOS), has shown growing evidence of improving insulin resistance, hyperandrogenism, dyslipidemia, overall cardiovascular health, quality of life, psychological wellbeing, and general health outcomes. This study aims to identify and summarize the effects of metformin in patients with PCOS-associated acne. This systematic review was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search was done on PubMed, PubMed Central, Cochrane, Google Scholar, and Science Direct databases from 2011 up to 23 February 2022. Randomized controlled trials (RCTs), cross-sectional studies, observational studies, literature reviews, systematic reviews, and meta-analyses published in English were selected. The data was extracted to a predefined template. Each study was individually checked by using a quality assessment. The initial search generated a total of 218 studies. Nine studies were included in the final selection: two RCTs, one hospital-based longitudinal study, one hospital-based clinical trial, three cross-sectional studies, three systematic reviews with meta-analyses, and one narrative review. Metformin is generally effective and safe for improving PCOS-associated acne and the quality of life. More clinical trials are required to determine the indications for prescribing metformin in patients with PCOS-associated acne.
Large-scale coronavirus disease 2019 (COVID-19) vaccination programs have been rolled out worldwide. Vaccines that are widely used globally include mRNA vaccines, adenoviral vector vaccines, and inactivated whole-virus vaccines. COVID-19 vaccines can lead to varying side effects. Among the most common of these adverse effects are pain at the injection site, fatigue, and headaches. Some side effects, however, are not very well documented, and these include joint-related adverse effects. In this review, we assess the epidemiology and clinical features of post-COVID-19 vaccination joint-related adverse effects based on the analysis of 16 patient case reports.Based on our analysis, we found that females formed the majority of the cases, accounting for 62.5% of patients, while 37.5% of the cases were males. The mean age of presentation among the patients was 54.8 years, with a standard deviation (SD) of 17.49 years. In 37.5% of the cases, patients received the Sinovac vaccine. The proportion of patients who received other vaccines was as follows: the Pfizer vaccine: 31.25%; Sputnik V: 12.5%; Moderna, AstraZeneca, and Covaxin: 6.25% each.The characteristics of joint-related adverse effects following COVID-19 vaccination were analyzed in this study. We identified several key findings related to factors such as age, gender, type of vaccine, clinical features, and diagnosis modality. Our analysis showed that more cases were reported among individuals who received the Sinovac vaccine, as compared to the others. Further research is required to examine the underlying cause of this association.
Neurodegenerative diseases, in particular Parkinson's disease (PD), a disabling disorder, require early attention due to the course the diseases take. By the time of clinical manifestation, dopaminergic neuron death would have already exceeded a damaging level. Therefore, the discovery of biomarkers that will effectively diagnose PD at an early stage and help monitor disease advancement is crucial. Out of the available biomarkers and bodily sources from which these can be isolated; alpha-synuclein (a-syn) from saliva seems to be a promising and easily accessible option. This has been further investigated in this systematic review.A comprehensive literature search on PubMed, PubMed Central (PMC), and Science Direct resulted in 1,439 articles. After screening and exclusion, 12 relevant articles were derived.In many of the studies, there was a decrease in total salivary a-syn in PD patients compared to healthy controls (HC), with an increase in oligo a-syn and oligo a-syn/total a-syn ratio as a rather consistent finding amongst the studies reviewed. On the other hand, a few studies revealed no significant difference in a-syn levels between the controls and PD patients. Another common finding was the lack of disease severity correlation with the marker, probably due to the scarcity of longitudinal studies conducted and smaller cohorts recruited in the studies.Overall, the total a-syn did show a genetic and phenotypic association, whilst oligo a-syn had the potential to serve as a biomarker for disease diagnosis. With the standardization of sample collection methods and diagnostic tools, and the accomplishment of longitudinal studies, further importance of salivary a-syn as a biomarker in PD could be established, utilizing the already existing data as an encouraging foundation for future research.
Polymyalgia rheumatica (PMR) and giant-cell arteritis (GCA) with symptoms of PMR share some pathophysiologic features. Interleukin 6 (IL-6) levels are elevated in both groups. We investigated the effect of tocilizumab (TCZ), an IL-6 inhibitor, in both populations and whether there were any differences regarding effectiveness and safety between them.We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines by searching the following databases: PubMed, PMC, Medline, Scopus, Cochrane Library, and ClincalTrials.gov.We found eight articles including one systematic review, one randomized controlled trial (RCT), one posthoc analysis of an RCT, and five observational studies. A total of 668 patients were included in this study. After a comprehensive analysis, we can only infer that there is insufficient evidence to suggest TCZ as monotherapy. Nevertheless, using TCZ in combination with glucocorticoid can be an effective therapeutic option.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
