Hydatic cyst prevalence in slaughtered animals, A neglected health problem

Lorestan and other part of Iran are one of the important endemic focuses for the major zoonotic parasitic diseases like cystic hydatid disease where several species of intermediate host are commonly infected with Echinococcus granulosus. Meat inspection records in a slaughtered house were used to determine the prevalence of Hydatidosis in sheep, cattle, and goats in Lorestan province (Aleshtar) located in South-West of Iran. The data were collected during a 5 year period from 2002 to 2006. A total of 40,431 animals (cattle 6993; sheep 14084; goats 19354) slaughtered in the 5-year period and overall 2885 (7.13%) lungs and 2885 (7.13%) livers and 1598 (3.95%) peritoneal cavity were contaminated by hydatid cyst. One thousand and eight hundred sixty eight (26.71%) out of 6993 of cattle, 2989/14084 (21.22%) of sheep and 2511/19354 (12.97%) of goats were infected by hydatid cyst in liver, lung and peritoneal cavity respectively. This study indicates that the highest prevalence of Hydatidosis was found in Aleshtar, Lorestan as compared to the rest of Iran (p<0.05). The annual prevalence of lung condemnations due to hydatidosis was increased from 8.3, 5 and 1.3% in Sep 2002 to Sep 2003 to 20.5, 8 and 5.5 % in Sep2005 to Sep2006 for cattle, sheep, and goats, respectively. An urgent attention is required to work on lack of awareness among farmers, lack of a policy to destroy the infected organs, prevention of access of dogs to raw offal’s and other responsible factors.Lorestan and other part of Iran are one of the important endemic focuses for the major zoonotic parasitic diseases like cystic hydatid disease where several species of intermediate host are commonly infected with Echinococcus granulosus.

The Potential Anti-inflammatory Effect of Spirulina Platensis on an in Vitro Model of Celiac Disease

Background: Celiac disease (CD) is a prevalent autoimmune enteropathy triggered by the ingestion of gluten. The management of CD involves adhering to a gluten-free diet (GFD). Recent studies have been actively exploring potential supplementary or alternative therapies for individuals with CD. The primary objective of the present study was to assess the effectiveness of Spirulina platensis in regulating the intestinal barrier-related gene expression and alleviating inflammation and oxidative stress associated with CD in PT-gliadin-triggered Caco-2 cells.Methods: S. platensis extracts and a pepsin/trypsin (PT) digest of gliadin were prepared and exposed to the human colon carcinoma Caco-2 cell line. Cell viability was assessed. Total RNA was extracted from Caco-2 cells and cDNA synthesis was performed. A quantitative real-time polymerase chain reaction (qRT-PCR) assay was conducted to evaluate the mRNA levels of interleukin (IL)-6, transforming growth factor beta (TGF-β), COX-2, nuclear factor kappa B (NF-κB), ZO-1, and occludin.Results: Treating Caco-2 cells with S. platensis alone (P=0.01 for both) or in combination with PT-gliadin (P=0.004 and P=0.02, respectively) resulted in decreased IL-6 expression and increased occludin mRNA expression. Additionally, S. platensis extract enhanced Zo-1 mRNA levels (P=0.002) and reduced NF-κB mRNA expression (P=0.02). The combination of gliadin and S. platensis led to decreased mRNA expression of COX-2 (P=0.03) and NF-κB (P=0.04). No significant differences were observed in TGF-β mRNA expression between the studied groups (P>0.05).Conclusion: Additional investigation is needed to examine the influence of interactions between S. platensis and gliadin regarding the comprehensive response of CD to gliadin, encompassing the activation of gluten-sensitive immune cells

A trend of Medical Negligence in Laser Therapy in the Capital City: A Nine-Year Survey

Background: the purpose of the present study is to investigate the common causes of injuries, claims, and decisions related to laser therapy medical malpractice during a nine-year survey. Study design: This study is a retrospective descriptive study. Methods: The legal documents in the coroner’s Office of Forensic Medicine were investigated in a national database from 2012 to 2020 in Tehran, Iran. The frequency and nature of the cases, including the year of litigation, the location and certificate of the provider, the injury sustained, the cause of legal action and judgment were collected. Results: Three hundred and eighty-three cases related to injury from laser therapy were registered in the coroner’s Office of Forensic Medicine during the study period. The incidence of litigation related to laser surgery showed an increasing trend, with a peak occurrence in 2020. Laser hair removal was the most common (51.2%) litigated procedure. General practice operators (48%) recorded the highest rate of laser-related medical complaints. lack of skill was the most common reason for failure. Among 383 cases with public decisions, 62.4% of them were fault liability in paid judgment. Conclusions: Medical claims related to laser application are increasing. However, as it is clear, the growth of laser technology and the increasing demand for lasers in medical science require more surveillance to avoid probable injuries and improve patient safety, especially surveillance of the physicians who work outside the scope of their specialty.&nbsp

Fecal carriage of Escherichia coli and Klebsiella spp. as major reservoirs of clinically important resistance markers

Intestinal normal flora can become reservoirs of antibiotic resistance genes present among the strains responsible for nosocomial infections. It is suggested that gram negative intestinal bacterial flora have increased capacities to obtain antibiotic resistance genes and therefore can act as main reservoirs for transfer of resistance genes to other pathogenic bacteria. This study aimed to compare fecal carriage of clinically important resistance markers for more frequent members of enterobacteriacae between nondiarrheal and community associated diarrheal patients (control group) versus their counterparts from the patients with nosocomial infections (case group). 261 stool and 190 clinical samples were collected from outpatient and hospitalized patients from 6 hospitals in Tehran, Iran. The samples were cultured on MacConkey agar plates and colonies were identified by standard biochemical methods. Antibiotic sensitivity testing of the isolates against 13 antibiotics was performed according to the CLSI guideline using the disk diffusion method.   Among stool and clinical samples, more frequent identified enterobacteriaceae bacteria were included E. coli (58.99/ 3.15%), Klebsiella spp. (22.61/7.36%), and other members of enterobacteriaceae (8.86/1.06%), respectively. Overall, resistance against four of the main antibiotics (3th and 4th generation cephalosporins, gentamicin, imipenem, and ciprofloxacin) was significantly higher among the case group (50-75% versus 10-14%). Analysis of these results showed similar dissemination of resistance phenotypes among the isolates from the control group in ranges of 1.5-7.6% and 4.4% for E. coli and Klebsiella spp., respectively. Our results suggested that the fecal carriage of resistant phenotypes related to the β-lactam antibiotics in E. coli and Klebsiella spp. in compare to the clinical isolates is rapidly increasing. This may be caused by dissemination of β-lactamase producing E. coli in the community from the hospitals. There were no significant correlations between the two groups of the samples, as the clinical samples had shown 3 to 7 folds excess resistance phenotypes. Surveillance studies of the resistance patterns among the samples from different regions will provide awareness about dissemination of these bacteria within the community as reservoirs of main resistance markers

Potential Molecular Mechanisms of Bisphenol A in Obesity Development

Bisphenol A (BPA), an endocrine disruptor, is associated with metabolic disorders. However, several studies have suggested that exposure to BPA can cause obesity. It has recently got more attention from scientists as a risk factor for obesity due to its ability to mimic natural estrogens and bind to their receptors. Nonetheless, the molecular mechanism underpinning the environmental etiology of metabolic disorders has not been not fully clarified. In this regard, BPA exposure directly disrupts endocrine regulation, neuroimmune and signaling pathways, and gut microbes, resulting in obesity. In addition, epidemiological studies have revealed a significant relationship between BPA exposure and the development of obesity, although conflicting results have been reported. Therefore, this review summarized the possible role and molecular mechanisms associated with BPA exposure that may lead to obesity based on in vivo and in vivo studies

The The Effect of 2.45 GHz Electromagnetic Fields on Fear Memory Extinction in Male Rats

Emotional and environmental factors influence the extinction of fear memories. To evaluate the possible risks, we investigated the effect of 2.45 GHz microwave radiation on rats' fear learning and memory capacity. The present study aimed to assess the impacts of corticosterone levels on the consolidation and reconsolidation of fear-conditioning memories. The rats were evaluated in contextual fear conditioning using foot shocks in both the short-term (7 days) and the long-term (30 days). Exposure was carried out on young male Wistar rats for 5–6 weeks continuously (1 h/day) with radio frequency electromagnetic field radiation possessing a frequency, power density, and pulse width of 2.45 GHz, 6.0 mW/cm2, and 2 ms, respectively. Several animals housed without exposure to radiation under identical conditions are controlled. Based on the results obtained in this research, a decrease in body weight and percentage of freezing time was observed after the long-term exposure groups significantly. As corticosterone levels were analyzed, they did not alter their responses after the conditioning fear memory test

Evaluation of the Cellular Resistance Process in Treated Cells Via Extracorporeal Photopheresis: Cellular resistance in treated cells via extracorporeal photopheresis

Introduction: Extracorporeal photopheresis (ECP) is a therapeutic method applied against some diseases such as cancers. Using 8-methoxypsoralen (8-MOP) and UVA radiation in ECP is associated with achievement in the treatment of patients with leukemic cutaneous T-cell lymphoma (CTCL). Evaluation of cellular resistance versus ECP is the aim of this study.Methods: Data were downloaded from the Gene Expression Omnibus (GEO) database and were analyzed via the GEO2R program. The significant DEGs were assessed via protein-protein interaction (PPI) network analysis by using the STRING database and Cytoscape software. The critical genes were evaluated via gene ontology by using the ClueGO application of Cytoscape software. The identified biological processes were determined and analyzed.Results: Fifty-seven significant DEGs were determined. The main connected component of the PPI network including 32 queried significant DEGs plus 50 first neighbors was constructed. Nineteen histones as critical nodes were assessed via gene ontology, and “nucleosome organization” was pointed out as a crucial biological process. Finally, 15 histones from H2A, H2B, and H3 histone families were identified as the key genes that are involved in the resistance property of the treated cells.Conclusion: In conclusion, 15 members of H2A, H2B, and H3 families (especially H2A family) were considered as the origin of resistance versus ECP treatment. It is concluded that sensitivity to ECP treatment depends on gross molecular events which are involved in the functions of histones

The Effectiveness of Photobiomudulation therapy (PBMT) in COVID-19 Infection: PBM therapy and COVID19

Introduction: Currently, the COVID-19 pandemic is an important health challenge worldwide.  Due to the cytokine storm, the mortality rate in acute respiratory distress syndrome (ARDS) is high, but until now no therapy for these patients was approved. The aim of this review was to discuss the possible anti-inflammatory effect of photobiomodulation therapy on ARSD patients and present the potential role of low-level laser therapy in the improvement of respiratory symptoms associated with SARS-COV2. Methods: Studies about photobiomodulation therapy in inflammation and ARSD patients were examined. A primary search with reviewing English-language citations between 2005 and 2020 using the keywords COVID-19, ARDS, cytokine storm, low-level laser therapy, anti-inflammatory, and photobiomodulation was performed. The initial search yielded 818 articles; however, 60 articles were selected and discussed in the present study. Results: The results of the selected studies showed the usefulness of PBMT in the treatment of inflammation and ARSD in patients with COVID-19 infection. This therapy is non-invasive and safe to modulate the immune responses in ARSD patients. Conclusion: PBMT can potentially reduce the viral load and bacterial super-infections in patients with COVID-19 infection and control the inflammatory response. Therefore, the use of PBMT could be an efficient strategy for preventing severe and critical illness in SARS-COV2 infection

Low-Level Laser Therapy Effects on Rat Blood Hemostasis Via Significant Alteration in Fibrinogen and Plasminogen Expression Level: Low Level Laser Therapy Effects on Rat Blood Hemostasis

Introduction: There are many documents about the significant role of low-level laser therapy (LLLT) in different processes such as regenerator medicine and bone formation. The aim of this study is to assess the role of LLLT in blood hemostasis in rats via bioinformatic investigation.Methods: The differentially expressed plasma proteins of treated rats via LLLT from the literature and the added 50 first neighbors were investigated via network analysis to find the critical dysregulated proteins and biological processes by using Cytoscape software, the STRING database, and ClueGO.Results: A scale-free network including 55 nodes was constructed from queried and added first neighbor proteins. Fibrinogen gamma, fibrinogen alpha, and plasminogen were highlighted as the central genes of the analyzed network. Fibrinolysis was determined as the main group of biological processes that were affected by LLLT.Conclusion: Findings indicate that LLLT affects blood hemostasis which is an important point inapproving the therapeutic application of LLLT and also preventing its possible complication.
