Storytelling in Pregnancy and Childbirth: An Integrative Review of the Literature.

Methods: An integrative review of the literature was conducted, including peer-reviewed articles published between 2001 and 2022. The following databases were used to search for relevant studies: PubMed, CINAHL, PsycINFO, Web of Science, Ovid, Google Scholar, ScienceDirect, Cochrane Library, Magiran, Irandoc, and SID. A process of thematic synthesis was used to make sense of the data extracted. Results: Whilst 21 studies were retrieved, only 12 were relevant and thus met the inclusion criteria set. Two themes were identified from our thematic synthesis: (1) effects of childbirth storytelling on the storyteller and (2) effects of childbirth storytelling on the listener of the story. Subthemes included "reducing fear of childbirth," "transferring information and raising awareness in line with community culture," and "adjusting expectations." Conclusion: The use of storytelling can be used as an effective method in educational interventions during pregnancy and childbirth. Due to limited high-quality intervention studies in this field, future studies could usefully be more robustly designed and incorporate digital storytelling methods to inform future directions.

Core-shell nanoparticles used in drug delivery-microfluidics: a review.

Developments in the fields of lab-on-a-chip and microfluidic technology have benefited nanomaterial production processes due to fluid miniaturization. The ability to acquire, manage, create, and modify structures on a nanoscale is of great interest in scientific and technological fields. Recently, more attention has been paid to the production of core-shell nanomaterials because of their use in various fields, such as drug delivery. Heterostructured nanomaterials have more reliable performance than the individual core or shell materials. Nanoparticle synthesis is a complex process; therefore, various techniques exist for the production of different types of nanoparticles. Among these techniques, microfluidic methods are unique and reliable routes, which can be used to produce nanoparticles for drug delivery applications.

Association between biofilm production, adhesion genes and drugs resistance in different SCCmec types of methicillin resistant Staphylococcus aureus strains isolated from several major hospitals of Iran.

OBJECTIVES: The ability of bacteria to produce biofilm and adhesion makes them more resistant to antibiotics. The current study aims to evaluate the biofilm formation by Staphylococcus aureus and to determine the prevalence of adhesion genes, also their correlation with drug resistance. MATERIALS AND METHODS: A total of 96 MRSA were collected from hospitals of Iran's western provinces during 2012 to 2013. The presence of ica A, B, C, D, clfA, cna, fnbA, mecA genes were determined by PCR technique. Biofilm formation was studied by microtiter plate assay, the clonal relations of the strains were examined by SCCmec and Spa typing. RESULTS: The results demonstrated that 96 % of isolates were biofilm producers. The distributions of biofilm formation between isolates were 4.2%, 54.2%, 35.4% as high, moderate and weak, respectivelly. The highest biofilm production was observed from blood culture isolates. All virulent genes icaA,B, C, D, clfA, cna, fnbA were observed in moderate and weak biofilm formation isolates. Among high biofilm formation isolates, icaB and cna genes were not seen. Statistical analysis showed that there was a significant correlation between ica, fnbA and the biofilm production, but there was not a significant correlation between the type of samples and drug resistance, spa type and SCCmec type with biofilm production (P>0.05). Frequency of All virulent genes in type III SCCmec was higher than other types. CONCLUSION: The majority of MRSA isolates were biofilm producers and blood isolates ranked as the great biofilm producer. In these isolates ica D and fnbA genes are correlated with biofilm production.

3rd Generation of Cephalosporins and Monobactam Resistant Among Pathogenic Bacteria Collected from Ilam Hospitals During 2008 to 2015: A Systematic Review and Meta-Analysis.

BACKGROUND: Recently, increasing antibiotic resistance is causing serious publichealth concerns worldwide. This phenomenon increased patient's morbidity and mortality rate, particularly in immunocompromised individuals. METHODS: Considering that antimicrobial resistance can vary according to geographical location, we investigated the status of antibiotic resistance in Ilam province from 2008 to 2013. RESULTS: The results of our study showed that antibiotic resistance rates to aztreonam, cefotaxime, ceftazidime and ceftriaxone were 38%, 39%, 43% and 48% respectively. CONCLUSION: Antibiotic resistance had increased (except for aztreonam) during the period from 2008 to 2013.

The correlation between the presence of quorum sensing, toxin-antitoxin system genes and MIC values with ability of biofilm formation in clinical isolates of Pseudomonas aeruginosa.

INTRODUCTION: Pseudomonas aeruginosa is a Gram-negative bacterium that considered as important opportunistic human pathogen. One of the mechanisms that help bacteria to tolerate survival in adverse conditions and resistance to antibiotics is biofilm formation through quorum sensing (QS) signals and toxin-antitoxin (TA) systems. QS and TA are two systems that have important roles in biofilm formation. QS is a global regulatory mechanism that enable bacteria to communicate with each other by production of auto inducers (AI) molecules in population. Because of importance biofilm formation in P. aeruginosa infections, here, we studied frequency of QS and TA genes among clinical isolates of P. aeruginosa with ability of biofilm formation. MATERIALS AND METHODS: One hundred and forty clinical isolates of P. aeruginosa were collected from Tehran and Ilam hospitals. The isolates were identified by biochemical tests. Biofilm formation was evaluated by microplate method. After DNA extraction by boiling method, the frequency of QS genes (lasIR, rhlIR), and TA genes (mazEF, relBE, hipBA, ccdAB and mqsR) were analyzed by PCR. RESULTS: Our results showed that maximum resistance is related to aztreonam (72.85%) antibiotic. Most of isolates were able to produce biofilm (87.15%) and the majority of them formed strong biofilm (56.42%). PCR results showed that frequency of mazEF, relBE, hipBA, ccdAB, mqsR, lasIR and rhlIR genes were 85.71, 100, 1.42, 100, 57.14, 93.57 and 83.57 percent, respectively. CONCLUSION: Clinical isolates of P. aeruginosa had high ability to form biofilm, and QS and TA system genes among these isolates were very high (except hipBA genes). There are significaut correlation between biofilm for mation and present of QS and TA system genes.
