Objectives: The present study aimed to find a possible association between the vitamin D receptor (VDR) TaqI and the BsmI gene polymorphisms in relation to the serum levels of calcium (Ca) and vitamin D and the risk of urolithiasis. Methods: This case-control study was conducted on 68 children with urolithiasis and 67 healthy controls for the VDR gene polymorphisms using the polymerase chain reaction-restriction length polymorphism method. Results: The frequency of TaqI C allele was 36% in patients compared to 32.1% in controls (P = 0.49). A significantly higher frequency of the TaqI CC genotype was found among patients in the age group > 5 to 10 years. No significant difference was detected in the frequency of the BsmI A allele between patients (41.9%) and controls (42.5%, P = 0.91). However, a significantly lower frequency of the BsmI AA genotype was detected compared to those patients with Ca levels of > 10.8 mg/dL among patients with Ca levels of ≤ 10.8 mg/dL. Conclusions: Based on the results, a lack of an association between the VDR TaqI and BsmI polymorphisms with the risk of urolithiasis among children from Western Iran. However, a higher frequency of the TaqI CC genotype was found in the age group > 5 to 10 years. In addition, lower levels of Ca in patients were related to a significantly lower frequency of the BsmI AA genotype. The VDR gene BsmI polymorphism might affect the calcium level and the calcium metabolism in urolithiasis.","PeriodicalId":507382,"journal":{"name":"Journal of Kermanshah University of Medical Sciences","volume":"120 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the frequency of genes resistant to antiseptics in Iranian bacterial isolates. Methods: The present study was conducted as a systematic review. The keywords in the titles or abstracts of articles published in Persian and English were monitored. The search was performed in databases without a time limit. Results: The results showed a total of 975 bacterial isolates. The most common disinfectant-resistant genes in gram-positive isolates were QacAB genes, with an average of 28.48; SMR gene, with an average of 19.8; and qacE and qacEΔ1 genes, with an average of 45 in gram-negative isolates. Gram-negative isolates containing qacE and qacEΔ1 genes were mainly detected in patients hospitalized in intensive care, internal diseases, and infectious diseases wards and from trachea and urine samples. Conclusions: The unique conditions of the intensive care units and the use of invasive tools such as urinary catheters were the leading causes of infection with resistant pathogens. In addition, diversity in infection control measures like the type, amount, and concentration of disinfectants used in different hospital departments were other reasons for resistance to antiseptics in medical environments. Indiscriminate use of antibiotics caused microbial resistance in the same way antibiotics did not affect many microbial diseases, and arbitrary use caused the highest microbial resistance.","PeriodicalId":507382,"journal":{"name":"Journal of Kermanshah University of Medical Sciences","volume":"4 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141686201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: This study aimed to determine the antibiotic susceptibility of clinical isolates from inpatients in three referral hospitals in Isfahan, Iran. Methods: Standard tests identified the organism and antibiotic susceptibility testing. Stratification was performed by place of infection (community, hospital), admission ward (ICU, non-ICU), and age group (< 20 versus > 20 years). Results: P. aeruginosa showed high susceptibility to colistin (100%) and amikacin (81.8%) followed by tobramycin (69.2%), ciprofloxacin (68.5%), meropenem (67.2%), cefepime (65.7%), ceftazidime (64.3%), and imipenem (63.3%). Community-acquired strains were significantly more susceptible to meropenem (81.6%), ciprofloxacin (77.1%), cefepime (77.1%), imipenem (74.3%), and ceftazidime (72.2%) than nosocomial strains. Non-ICU isolates were more susceptible to carbapenems. P. aeruginosa isolates had higher antibiotic susceptibility in less than 20 years. Conclusions: Based on the results, a combination of colistin and amikacin would be appropriate for the empiric treatment of suspected P. aeruginosa infections in severe cases, nosocomial infections, or patients admitted to ICU. Ceftazidime, cefepime, ciprofloxacin, meropenem, or imipenem would be suitable for mild to moderate infections, especially in community-acquired infections.","PeriodicalId":507382,"journal":{"name":"Journal of Kermanshah University of Medical Sciences","volume":"31 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140425006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The present study aimed to determine the prevalence of vaccine acceptance, side effects, and factors encouraging/disincentivizing vaccination among healthcare workers. Methods: A descriptive-analytical cross-sectional study was conducted on 315 health workers at Imam Reza Hospital, Kermanshah, Iran, in 2021. The samples were selected through a simple random sampling method. The data collection tool was a researcher-made questionnaire, and the collected data were analyzed in STATA-17 software. Results: The vaccine acceptance rate was 84.1% (n = 265), and the vaccine refusal rate was 15.9% (n = 50). The most injected vaccines were Sinopharm (n = 112, 42.3%) and Sputnik (n = 88, 33.2%), respectively. The most common side effects after vaccine injection were fatigue (34.8%, n=39) and myalgia (14.3%, n = 16). Being in a high-risk place (n = 199, 75.2%) and fear of contracting COVID-19 (n = 88, 33.5%) were the most important reasons for encouraging vaccination. About 36.7% (n = 18) of blood clotting, 26.5% (n = 14) cardiac arrest, short-term safety, and distrust were the essential factors for not accepting the vaccine. Conclusions: Based on the results, the prevalence of vaccine acceptance among health workers was high. However, a small percentage did not want to accept the vaccine due to negative news and a lack of trust in the vaccine. Therefore, it is necessary to establish strong educational and awareness-raising associations that transmit knowledge of the COVID-19 vaccine by focusing on false information.","PeriodicalId":507382,"journal":{"name":"Journal of Kermanshah University of Medical Sciences","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140433426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the genetic variation of the HA gene to enhance global influenza virus surveillance. Objectives: The primary objectives of this research included molecular characterization and phylogenetic analysis of the influenza A/H3N2 HA gene. Therefore, this research aimed to contribute valuable insights to influenza surveillance efforts on a global scale by identifying the variants associated with vaccine escape and antigenic shift. Methods: RNA extraction was performed on 300 nasopharyngeal swab samples from patients with influenza-like illness using a commercial kit. The presence of influenza A/H3N2 was determined using qRT-PCR. Subsequently, positive samples underwent HA gene amplification through RT-PCR using the Sanger method. Variability in HA immunological sites was compared with reference sequences, and genotype/subtype was determined. Alignment and phylogenetic analyses were conducted to construct a tree utilizing an optimal nucleotide substitution model Results: Among the 300 samples, 22 (7.33%) tested positive for influenza A/H3N2, with a male distribution of 13 cases. The mean age of the participants was 35 ± 2.40 years. The analysis of antigenic site mutations revealed significant variations (A, B, D, and E) in the HA gene, with major mutations at positions 140 and 186. Noteworthy mutations such as S159Y and the previously undocumented K83R substitution at antigenic site E. Phylogenetic analysis classified the A/H3N2 strain into clades 3C.2a and 3C.3. Conclusions: The identified mutations in the HA gene suggest potential changes in antigenicity, emphasizing their relevance to vaccine development and surveillance strategies. It is recommended that ongoing molecular investigations be conducted for effective influenza control; also, the ongoing need to monitor influenza viruses is suggested to be highlighted. This research provides valuable insights necessary for maintaining efficient influenza control measures globally.","PeriodicalId":507382,"journal":{"name":"Journal of Kermanshah University of Medical Sciences","volume":"97 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140444140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
