High prevalence of HPV-56 and HPV-39 in Sari, Iran: an analysis of genotype distribution.

BACKGROUND: Human papillomavirus (HPV) is responsible for the most common sexually transmitted infection, particularly among sexually active individuals. Understanding the geographical distribution and epidemiology of the most prevalent HPV genotypes is essential for developing effective prevention strategies. Consequently, this study aimed to examine the distribution of HPV genotypes among HPV-positive women and men in Sari, the capital city of Mazandaran province in northern Iran. MATERIALS AND METHODS: HPV DNA was extracted (PZP Company, Molecular IVD, Iran) from genital and cervical samples of the study participants. Genotyping was conducted for 90 cases utilizing the High + Low Papilloma Strip test (Operon Company, Spain). Demographic data were statistically analyzed in correlation with the virological data (STATA version 17). RESULTS: Overall, 67.7% (61 out of 90) of the cases tested positive for HPV, with 75% of those being classified as high-risk. The participant group consisted of 92% females (83) and 8% males (7). The highest HPV prevalence, 75% (36), was observed in females and males aged under 31, with the majority of positive cases belonging to high-risk genotypes. The most frequently identified genotypes were HPV-11 (23%), HPV-6 (21%), HPV-56 (18%), HPV-39 (16%), HPV-16, HPV-91, and HPV-66 each comprising (14%). HPV-56 was the most common high-risk genotype, accounting for 11 cases (18%), followed by HPV-39, which was present in 10 cases (16%). CONCLUSION: The prevalence of HPV infection was particularly high among individuals under the age of 31 for both genders, with men exhibiting a 100% infection rate. These findings emphasize the urgent need for targeted education aimed at the younger population and the implementation of infection control measures. Specifically, widespread HPV vaccination targeting HPV-6, HPV-11, HPV-39, and HPV-56 should be prioritized for the general population.

The entire plant, including the leaves, fruit, roots, and flowers, has various therapeutic characteristics used for centuries to cure various illnesses. This systematic review aimed to identify an inexpensive, simple, and effective method of preventing and controlling dental caries. The search was performed among the studies written in English, the database of abstracts concentrating on the effects of Mangifera indica (Mango) on dental caries detected in Pubmed, Scopus, Google Scholar, and Central. In total, we find 37 articles. The relevant English language articles published up to August 2022 were collected, screened, and reviewed. Search words contained "Mangifera indica" and "dental caries" or "Streptococcus mutans" or "tooth demineralization." For our systematic review analysis, we included 3 randomized controlled trial studies studying a total of 130 people, of whom 110 were children aged 8 to 14 and 20 were adults aged 20 to 25. These experiments all employed mouthwash containing an extract from Mangifera indica. In conclusion, it has been proven in 2 separate studies that saliva's PH will increase significantly. In addition, a reduction of S. mutants has been observed in another research. Overall, it was concluded that mango extract mouthwash is highly effective in decreasing the bacteria that can cause dental caries. however, we firmly believe that conduction of more detailed in vivo studies regarding Mangifera indica implications in dental caries treatment is essentially needed for further confirmation.

Effect of Microalgae Arthrospira on Biomarkers of Glycemic Control and Glucose Metabolism: A Systematic Review and Meta-analysis.

Diabetes mellitus and insulin resistance are associated with an increased risk of cardiovascular disease (CVD) incidence and a higher rate of CVD-related death. In this study, the effects of Arthrospira (Spirulina) a blue-green algae supplementation on biomarkers of glycemic control and glucose metabolism has been evaluated. PubMed, Scopus, and ISI Web of Science were searched systematically of English human subjects and PubMed for pre-clinical animal studies (rats and mice) from January 2008 until November 2020. The pooled weighted mean difference (MD) and its 95% confidence interval (CI) were calculated and pooled using a random-effect model. Seven clinical and 27 preclinical studies were included. Pooled results of the clinical studies showed that Arthrospira supplementation significantly reduced the fasting blood sugar (FBS): (0.63- 2.90-) 1.77-, total cholesterol (TC): (0.46- ، 4.61-) 2.54-, triglycerides (TG): (0.89- ، 6.54-) 3.71- and increased the high-density lipoprotein cholesterol (HDL-C): (3.86 ، 0.67) 2.27; however, Arthrospira was not significantly effective in terms of reducing the glycated hemoglobin A1c (HbA1C): (1.04 ، 2.23-) 0.59- and low-density lipoprotein cholesterol (LDL-C). Pooled results of preclinical studies showed that Arthrospira supplementation reduced FBS [-10.31 (-12.49, -8.13)] and HbA1C [-5.12 (-8.06, -2.19)] significantly in diabetic animals. Sub-group analysis of clinical studies showed that intervention duration less than 2 months [-2.52 (-4.37, -0.67)] and the dose less than 2 gram [-3.22 (-5.67, -0.76)] showed significant improvement in terms of reducing the FBS in humans. It can be concluded that Arthrospira can be considered as an effective FBS, TG, TC, and HDL-C adjusting nutraceutical agent for diabetes mellitus. Due to the differences in the results of clinical and animal studies in terms of HbA1c, more studies are needed for a definitive conclusion.

Selective serotonin reuptake inhibitors: New hope in the fight against COVID-19.

The emerging COVID-19 pandemic led to a dramatic increase in global mortality and morbidity rates. As in most infections, fatal complications of coronavirus affliction are triggered by an untrammeled host inflammatory response. Cytokine storms created by high levels of interleukin and other cytokines elucidate the pathology of severe COVID-19. In this respect, repurposing drugs that are already available and might exhibit anti-inflammatory effects have received significant attention. With the in vitro and clinical investigation of several studies on the effect of antidepressants on COVID-19 prognosis, previous data suggest that selective serotonin reuptake inhibitors (SSRIs) might be the new hope for the early treatment of severely afflicted patients. SSRIs' low cost and availability make them potentially eligible for COVID-19 repurposing. This review summarizes current achievements and literature about the connection between SSRIs administration and COVID-19 prognosis.

Recognition of (Sesc) for Easy Identification of Staphylococcus Epidermidis and Molecular and Phenotypic Study of Β-Lactam Resistance in Staphylococcus Epidermidis Isolates in Isfahan.

BACKGROUND: Not only is it crucial to rapidly detect Staphylococcus epidermidis (S. epidermidis) isolates from a broad range of bacteria, but recognizing resistance agents can greatly improve current diagnostic and therapeutic strategies. METHODS: The current cross-sectional study investigated 120 clinical isolates from a nosocomial S. epidermidis infection. The isolates were identified using common biochemical tests, and specific S. epidermidis surface protein C (SesC) primers were used to confirm the presence of S. epidermidis. PCR and special primers were used to detect the ß-lactamase gene (blaZ). Methicillin resistance was measured using the agar screening method and antibiotic susceptibility was measured by disk diffusion. RESULTS: 100 samples were characterized as S. epidermidis using a phenotypic and genotypic methods. From the 100 specimens examined, 80% contained blaZ. According to agar screening, 60% of isolates were methicillin-resistant. S. epidermidis isolates demonstrated the highest resistance to penicillin (93%) and the highest sensitivity to cefazolin (39%). CONCLUSION: The increased resistance to ß-lactam antibiotics in S. epidermidis isolates is alarming, and certain precautions should be taken by healthcare systems to continuously monitor the antimicrobial pattern of S. epidermidis, so that an appropriate drug treatment can be established.
