Mucormycosis, a serious and rare fungal infection, has recently been reported in COVID-19 patients worldwide. This study aims to map all the emerging evidence on the COVID-19-associated mucormycosis (CAM) with a special focus on clinical presentation, treatment modalities, and patient outcomes. An extensive literature search was performed in MEDLINE (Ovid), Embase (Ovid), Cochrane COVID-19 Study Register, and WHO COVID-19 database till 9 June 2021. The primary outcome was to summarize the clinical presentation, treatment modalities, and patient outcomes of CAM. Data were summarized using descriptive statistics and presented in tabular form. This evidence mapping was based on a total of 167 CAM patients with a mean age of 51 ± 14.62 years, and 56.28% of them were male. Diabetes mellitus (73.65% (n = 123)), hypertension (22.75% (n = 38)), and renal failure (10.77% (n = 18)) were the most common co-morbidities among CAM patients. The most common symptoms observed in CAM patients were facial pain, ptosis, proptosis, visual acuity, and vision loss. Survival was higher in patients who underwent both medical and surgical management (64.96%). Overall mortality among CAM patients was found to be 38.32%. In conclusion, this study found a high incidence of CAM with a high mortality rate. Optimal glycemic control and early identification of mucormycosis should be the priority to reduce the morbidity and mortality related to CAM.
Our study indicates that the NLRP3 rs4612666 polymorphism may be involved in the development of RAS in the Czech population.
Genetic factors, especially those related to immune system functioning, have been intensively studied to determine their role in the development of recurrent aphthous stomatitis (RAS). The aim of the present study was to analyze gene variability in interleukin (IL)2, IL4 (and its receptor α, IL4Rα), IL10, and IL13, which were selected based on literature review and/or their functional relevance, in Czech patients with RAS and in healthy controls. In total, 252 subjects (178 controls and 74 patients with RAS) were enrolled in this case–control study, and their detailed anamnestic, clinical, and laboratory data were obtained. Nine polymorphisms in the genes encoding interleukins were determined using PCR techniques. There were no significant differences in allele or genotype frequencies of the IL2, IL4, IL4Rα, IL10, and IL13 polymorphisms rs2069762/rs2069763, rs2243250/rs79071878, rs1801275, rs1800896, and rs1800925, respectively, between controls and patients with RAS. The minority alleles rs1800871 and rs1800872, which encode variants of IL10, were associated with a statistically significantly higher risk of RAS, as confirmed by the results of genotype and haplotype analyses. We suggest that variability in the IL10 gene may play an important role in the development of RAS in the Czech population.
Background Recurrent aphthous stomatitis (RAS) is multifactorial disease with unclear etiopathogenesis. The aim of this study was to determine distribution of the angiotensin I converting enzyme (ACE) gene polymorphisms and their influence on RAS susceptibility in Czech population. Methods The study included 230 subjects (143 healthy controls and 87 patients with RAS) with anamnestic, clinical and laboratory data. Five ACE gene polymorphisms (rs4291/rs4305/rs4311/rs4331/rs1799752 = ACE I/D) were determined by TaqMan technique. Results The allele and genotype distributions of the studied ACE I/D polymorphisms were not significantly different between subjects with/without RAS (Pcorr > 0.05). However, carriers of II genotype were less frequent in the RAS group (OR = 0.48, 95% CI = 0.21–1.12, P = 0.059). Stratified analysis by sex demonstrated lower frequency of II genotype in women (OR = 0.33, 95% CI = 0.09–1.17, P < 0.035, Pcorr > 0.05, respectively) than in men with RAS (P > 0.05). Moreover, the frequency of AGTGD haplotype was significantly increased in RAS patients (OR = 13.74, 95% CI = 1.70–110.79, P = 0.0012, Pcorr < 0.05). In subanalysis, TGD haplotype was significantly more frequent in RAS patients (P < 0.00001) and CGI haplotype was less frequent in RAS patients (P < 0.01), especially in women (P = 0.016, Pcorr > 0.05). Conclusions Our study indicates that while the AGTGD and TGD haplotypes are associated with increased risk of RAS development, CGI haplotype might be one of protective factors against RAS susceptibility in Czech population.
This is a protocol for a scoping review that aims to determine how guideline authors using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach have addressed previously identified challenges related to public health. The Joanna Briggs Institute (JBI) methodology for scoping reviews will be followed. We will search and screen titles of guidelines for all languages published in 2013–2021 in: the GIN library, BIGG database, Epistemonikos GRADE guidelines repository, GRADEpro Database, MAGICapp, NICE and WHO websites. Two reviewers will independently screen full texts of the documents identified. The following information will be extracted: methods used for identifying different stakeholders and incorporating their perspectives; methods for identification and prioritization of non-health outcomes; methods for determining thresholds for decision-making; methods for incorporating and grading evidence from non-randomized studies; methods for addressing concerns with conditional recommendations in public health; methods for reaching consensus; additional methodological concerns; and any modifications made to GRADE. A combination of directed content analysis and descriptive statistics will be used for data analysis, and the findings presented narratively in a tabular and graphical form. In this protocol, we present the pilot results from 13 identified eligible guidelines issued between January and August 2021. We will publish the full review results when they become available.
IntroductionPerioperative care is a broad field covering an array of elective and emergency procedures. Clinical practice guidelines (CPGs) for perioperative care exist with various degrees of methodological quality. We intend to critically appraise them using AGREE II instrument and investigate the use of Grading of Recommendations, Assessment, Development and Evaluations (GRADE).Methods and analysisWe searched MEDLINE (Ovid), Epistemonikos, Cochrane Database of Systematic Reviews and PROSPERO and did not identify any similar systematic review in this area. We will search databases, repositories and websites of guideline developers and medical societies, including MEDLINE (Ovid), Embase (Ovid), DynaMed, the GIN international guideline library and registry of guidelines in development, BIGG international database of GRADE guidelines, ECRI Guideline Trust or National Institute for Clinical Evidence to identify all CPGs for perioperative care in an adult population in a general clinical setting. We will include CPGs, expert guidance, position papers, guidance documents and consensus statements published in the last 5 years by experts or international organisations that provide guidance or recommendations in the available full text with no geographical or language limitation. Excluded will be those containing only good practice statements. Two independent reviewers will perform critical appraisal using the AGREE II tool. The data presented in a narrative and tabular form will include the results of the critical appraisal for all identified CPGs for all AGREE II domains and an assessment of the use of the GRADE approach.Ethics and disseminationEthics approval is not required. We will disseminate the findings through professional networks and conference presentations and will publish the results.
Background The development of recurrent aphthous stomatitis (RAS), inflammatory disease of oral mucosa, is influenced by both environmental and genetic factors. The aim of this study was to investigate polymorphisms located in seven genes coding different types of matrix metalloproteinases (MMPs)—collagenases (MMP1, MMP8, and MMP13), gelatinases (MMP2 and MMP9), stromelysin (MMP3), and membrane‐type metalloproteinase (MMP16) in patients with RAS and healthy controls. Methods Totally, 223 subjects were included in this case‐control study and their detailed anamnestic, clinical, and laboratory parameters were recorded. Seventy‐seven patients with RAS and 146 controls were genotyped for seventeen polymorphisms in the MMPs genes using the real‐time polymerase chain reaction (PCR) or PCR with restriction analysis. Results Allele, genotype, and haplotype frequencies of the studied polymorphisms between RAS patients and controls were similar, except for allele distributions of MMP1 rs1144393, MMP9 rs3918242, and MMP16 rs10429371, which were different between patients with RAS and healthy controls (P = .023, P = .049 and P = .025, all Pcorr > 0.05, respectively). Moreover, the comparison of genotype frequencies (TT vs CC + CT) of the MMP16 rs10429371 variant showed a marginally significant difference between RAS patients and controls (P = .05, Pcorr > 0.05, OR = 1.68, 95% CI = 0.95‐2.98). Conclusions No significant relationship between investigated polymorphisms in seven MMPs genes and RAS development in the Czech population was observed in this study.
