Review Citation - WoS: 6Citation - Scopus: 7Molecular Epidemiology of Carbapenem-Resistant Acinetobacter Baumannii Isolates in Turkiye: Systematic Review(Kare Publ, 2023) Kilbas, Elmas Pinar Kahraman; Kilbas, Imdat; Ciftci, Ihsan Hakki; Kahraman Kilbas, Elmas PinarThe World Health Organization has designated carbapenem-resistant Acinetobacter baumannii (CRAB) as a "critical" pathogen on the global priority list of antibiotic-resistant bacteria. This study aims to discuss the molecular epidemiology of CRAB isolates in Turkiye in the last 12 years and the prevalence of gene regions associated with resistance or pathogenesis using a systematic review method. Our study consists of a literature search, determination of eligibility and exclusion criteria, qualitative analysis of studies, data extraction, and statistical analysis. All studies were analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines. The incidence rates of blaOXA-23, blaOXA-23-like, blaOXA-24/40, blaOXA-24/40-like, blaOXA-51, blaOXA-51-like, blaOXA-58, and blaOXA-58-like genes in CRAB strains were 76.4%, 68.6%, 1.2%, 3.4%, 97.0%, 98.6%, 8.4%, and 17.1%, respectively. It was determined that the prevalence of the blaOXA-23 and blaOXA-58 gene regions showed a statistically significant change over the years. Due to the high prevalence of A. baumannii strains carrying the blaOXA-23 variant, it is necessary to follow its geographical distribution and transposon and plasmid movements. Based on available data, molecular surveillance of CRAB strains should be standardized. In addition, sterilization and disinfection processes applied within the scope of an effective struggle against CRAB strains that can remain live on surfaces for a long time should be reviewed frequently.Review Citation - WoS: 14Citation - Scopus: 18Managing Viral Emerging Infectious Diseases Via Current and Future Molecular Diagnostics(Mdpi, 2023) Altindis, Mustafa; Kilbas, Elmas Pinar Kahraman; Kahraman Kilbaş, Elmas PınarEmerging viral infectious diseases have been a constant threat to global public health in recent times. In managing these diseases, molecular diagnostics has played a critical role. Molecular diagnostics involves the use of various technologies to detect the genetic material of various pathogens, including viruses, in clinical samples. One of the most commonly used molecular diagnostics technologies for detecting viruses is polymerase chain reaction (PCR). PCR amplifies specific regions of the viral genetic material in a sample, making it easier to detect and identify viruses. PCR is particularly useful for detecting viruses that are present in low concentrations in clinical samples, such as blood or saliva. Another technology that is becoming increasingly popular for viral diagnostics is next-generation sequencing (NGS). NGS can sequence the entire genome of a virus present in a clinical sample, providing a wealth of information about the virus, including its genetic makeup, virulence factors, and potential to cause an outbreak. NGS can also help identify mutations and discover new pathogens that could affect the efficacy of antiviral drugs and vaccines. In addition to PCR and NGS, there are other molecular diagnostics technologies that are being developed to manage emerging viral infectious diseases. One of these is CRISPR-Cas, a genome editing technology that can be used to detect and cut specific regions of viral genetic material. CRISPR-Cas can be used to develop highly specific and sensitive viral diagnostic tests, as well as to develop new antiviral therapies. In conclusion, molecular diagnostics tools are critical for managing emerging viral infectious diseases. PCR and NGS are currently the most commonly used technologies for viral diagnostics, but new technologies such as CRISPR-Cas are emerging. These technologies can help identify viral outbreaks early, track the spread of viruses, and develop effective antiviral therapies and vaccines.Review Citation - WoS: 3Citation - Scopus: 3Age-Specific Seroprevalence of Hepatitis a Virus in Turkey Between 2000 and 2023: Systematic Review and Meta-Analysis(Mdpi, 2024) Ciftci, Ihsan Hakki; Koroglu, Mehmet; Demiray, Tayfur; Terzi, Huseyin Agah; Kilbas, Elmas Pinar Kahraman; Kahraman Kilbas, Elmas Pinar<bold>Background</bold>: Hepatitis A virus (HAV) is a leading cause of acute viral hepatitis and is primarily transmitted by the fecal-oral route. The clinical presentation and progression of the disease varies according to the age of the patient. Turkey is classified as a moderately endemic country, and HAV infection continues to be an important public health problem worldwide. <bold>Methods</bold>: In this study, a systematic meta-analysis was conducted to evaluate age-specific HAV seroprevalence rates in Turkey between 2000 and 2023. A comprehensive literature review identified 57 articles that met the inclusion criteria. The studies were assessed for quality, and seroprevalence rates were evaluated across four different age groups. Statistical analyses were performed using Comprehensive Meta-Analysis (CMA) software (CMAVersion 3.0) and SPSS (SPSS Statistics 25.0). <bold>Results</bold>: HAV seroprevalence rates were found to be 73.18% in the 0 < 5 age group and 90.90% in the >35 age group. The overall seroprevalence estimated using a random effects model was 64.5% (95% CI: 58.3-70). High heterogeneity was observed among the studies, and the prevalence estimates changed when low-quality studies were excluded. <bold>Conclusions</bold>: This meta-analysis suggests that the increasing trend in HAV IgG seroprevalence in Turkey, especially among young populations, is likely due to the vaccination program initiated in 2012. Furthermore, the heterogeneity observed among regions highlights the importance of regional public health strategies. Future studies should focus on providing more detailed data to evaluate the long-term effects of vaccination and to explain regional differences in HAV seroprevalence.<br />Article Saliva in the Diagnosis of Covid-19(Galenos Publ House, 2021) Kilbas, Elmas Pinar Kahraman; Altindis, Mustafa; Kahraman Kilbaş, Elmas PinarThe use of saliva samples for the diagnosis of severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) provides several advantages over the use of nasopharyngeal (NP) swabs, such as comfort, ease of self-collection, less use of personal protective equipment, and protection of healthcare personnel from transmission. This review included current studies using saliva samples for the detection of SARS-CoV-2, comparing its sensitivity, cycle threshold, and specificity with those of NP swab. In the literature, the sensitivity rates of saliva samples in the diagnosis of SARS-CoV-2 ranged from 70% to 98%. Despite different opinions, we concluded that saliva is a reliable sample for the detection of SARS-CoV-2. However, studies with large samples and comparing different diagnostic methods are needed to reach precise and reliable results and include saliva collection in diagnostic guidelines.
