Molecular epidemiology of carbapenem-resistant Acinetobacter baumannii isolates in Turkiye: Systematic review.

The 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.

Managing Viral Emerging Infectious Diseases via Current and Future Molecular Diagnostics.

Emerging 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.

Greater traditionalism predicts COVID-19 precautionary behaviors across 27 societies.

People vary both in their embrace of their society's traditions, and in their perception of hazards as salient and necessitating a response. Over evolutionary time, traditions have offered avenues for addressing hazards, plausibly resulting in linkages between orientations toward tradition and orientations toward danger. Emerging research documents connections between traditionalism and threat responsivity, including pathogen-avoidance motivations. Additionally, because hazard-mitigating behaviors can conflict with competing priorities, associations between traditionalism and pathogen avoidance may hinge on contextually contingent tradeoffs. The COVID-19 pandemic provides a real-world test of the posited relationship between traditionalism and hazard avoidance. Across 27 societies (N = 7844), we find that, in a majority of countries, individuals' endorsement of tradition positively correlates with their adherence to costly COVID-19-avoidance behaviors; accounting for some of the conflicts that arise between public health precautions and other objectives further strengthens this evidence that traditionalism is associated with greater attention to hazards.

Family still matters: Human social motivation across 42 countries during a global pandemic.

The COVID-19 pandemic caused drastic social changes for many people, including separation from friends and coworkers, enforced close contact with family, and reductions in mobility. Here we assess the extent to which people's evolutionarily-relevant basic motivations and goals-fundamental social motives such as Affiliation and Kin Care-might have been affected. To address this question, we gathered data on fundamental social motives in 42 countries (N = 15,915) across two waves, including 19 countries (N = 10,907) for which data were gathered both before and during the pandemic (pre-pandemic wave: 32 countries, N = 8998; 3302 male, 5585 female; M age  = 24.43, SD = 7.91; mid-pandemic wave: 29 countries, N = 6917; 2249 male, 4218 female; M age  = 28.59, SD = 11.31). Samples include data collected online (e.g., Prolific, MTurk), at universities, and via community sampling. We found that Disease Avoidance motivation was substantially higher during the pandemic, and that most of the other fundamental social motives showed small, yet significant, differences across waves. Most sensibly, concern with caring for one's children was higher during the pandemic, and concerns with Mate Seeking and Status were lower. Earlier findings showing the prioritization of family motives over mating motives (and even over Disease Avoidance motives) were replicated during the pandemic. Finally, well-being remained positively associated with family-related motives and negatively associated with mating motives during the pandemic, as in the pre-pandemic samples. Our results provide further evidence for the robust primacy of family-related motivations even during this unique disruption of social life.

Fundamental social motives measured across forty-two cultures in two waves.

How does psychology vary across human societies? The fundamental social motives framework adopts an evolutionary approach to capture the broad range of human social goals within a taxonomy of ancestrally recurring threats and opportunities. These motives-self-protection, disease avoidance, affiliation, status, mate acquisition, mate retention, and kin care-are high in fitness relevance and everyday salience, yet understudied cross-culturally. Here, we gathered data on these motives in 42 countries (N = 15,915) in two cross-sectional waves, including 19 countries (N = 10,907) for which data were gathered in both waves. Wave 1 was collected from mid-2016 through late 2019 (32 countries, N = 8,998; 3,302 male, 5,585 female; Mage = 24.43, SD = 7.91). Wave 2 was collected from April through November 2020, during the COVID-19 pandemic (29 countries, N = 6,917; 2,249 male, 4,218 female; Mage = 28.59, SD = 11.31). These data can be used to assess differences and similarities in people's fundamental social motives both across and within cultures, at different time points, and in relation to other commonly studied cultural indicators and outcomes.

[Investigation of blaOXA-48-like genes in carbapenemase producing Klebsiella spp. isolates]. / Karbapenemaz üreten Klebsiella pneumoniae suslarinda blaoxa-48-benzeri genlerin arastirilmasi.

The emergence and spread of multi-drug-resistant (MDR), extended-spectrum beta-lactamase (ESBL) producing carbapenem-resistant members of Enterobacteriaceae family has become a worldwide health problem. Carbapenem resistance caused by blaKPC, blaNDM gene regions are sporadic and blaOXA-48 gene region is endemic in our country. The aim of this study was to determine the presence of blaOXA-232, blaOXA-181, blaOXA-162, blaOXA-204, blaOXA-244, blaOXA-163, blaOXA-245 genes in OXA-48 like carbapenemase producing Klebsiella pneumoniae isolates. The isolates used in this study were provided from the Medical Microbiology Laboratory collection of Sakarya University Sakarya Training and Research Hospital. Identification and antibiotic susceptibility tests were determined by the VITEK 2® automated system (biomerieux, France) and the carbapenemase production of isolates was determined by the modified Hodge test. Minimal inhibitor concentration (MIC) values were determined with broth microdilution method. The isolates containing the blaOXA-48-like gene region were identified by real-time polymerase chain reaction (Rt-PCR) method using consensus primers. In "High Resolution Melting Analysis (HRMA)" method carried out by using "Type-it HRM PCR" (Qiagen, Hilden, Germany) kit, isolates which showed a deviation in melting temperatures (Tm) were selected with the suspicion of OXA-48 variant. The sequence analysis (ABI 3500, Applied Biosystems, USA) was carried out to determine which variants were present in these isolates. Compatibility of MIC values was determined between VITEK 2® and the microdilution method with the rate of 82% for imipenem, 77% for meropenem and 90% for ertapenem in carbapenemase-producing K.pneumoniae isolates. In 45 of 100 K.pneumoniae isolates, the blaOXA-48-like gene region was found to be positive by the Rt-PCR method. For the determination of OXA-48 variants, these 45 isolates were evaluated by HRMA method. The sequence analysis revealed that 41 (91.2%) isolates contained blaOXA-48/blaOXA-245 gene regions, while 2 (4.4%) isolates were found to contain blaOXA-181 gene regions and 2 (4.4%) isolates were found to contain blaOXA-244 gene regions. This is the first study to determine OXA-48 and OXA-244 positivity in blaOXA-48-like gene regions in Turkey. As a result of this study, the OXA-48-like gene region was found to be 45%, of which 4.4% had blaOXA-181 and 4.4% had blaOXA-244 gene regions. The detection of blaOXA-48-like gene regions will guide for the selection of antibiotics in critical patient groups.

Involvement of cannabinoid CB1 receptors in the antinociceptive effect of dipyrone.

Cannabinoid CB1 receptors have been implicated in the antinociceptive effect of paracetamol. In the current study, we examined whether blockade of CB1 receptors prevent the analgesic activity of dipyrone, in a similar way to paracetamol. Hot-plate and tail-flick tests were used to assess the antinociceptive activity in mice. Dipyrone and WIN 55,212-2, a cannabinoid agonist, exerted significant antinociceptive effects in both hot-plate and tail flick tests. The CB1 receptor antagonist, AM-251 (3 mg/kg), at a dose which had no effect when used alone, did not alter the antinociceptive effect of dipyrone, whereas completely prevented the antinociceptive activity of WIN 55,212-2 in both thermal antinociceptive tests. Our findings suggest that, unlike paracetamol, cannabinoid CB1 receptors do not participate in the antinociceptive action of dipyrone when acute pain tests used.
