INTRODUCTION: Selection of an acceptable method for the treatment of posterior urethral disruption defects would be highly desirable. We determined the efficacy and success rate of some techniques including supracrural rerouting for removing of these defects among our patients. MATERIALS AND METHODS: Records of 200 consecutive men treated with anastomotic urethroplasty for traumatic posterior urethral strictures were reviewed at our teaching hospital. Prior treatment, surgical approach, and ancillary techniques required during reconstruction were evaluated. RESULTS: Success rate due to posterior urethral reconstruction was achieved in 78.0% of cases. Supracrural urethral rerouting was performed in 11 patients (5.5%), of whom 7 sustained recurrent stricture requiring intervention. The highest success rate of defect resolving was reported by urethral mobilization (92.4%). CONCLUSION: Supracrural rerouting is not an acceptable technique and can result in postoperative complications such as recurrent stricture in most of the patients with posterior urethral disruption defects.

INTRODUCTION: The objective of this study was to evaluate the value of serum prostate-specific antigen (PSA) and prostate-specific antigen density (PSAD) in the diagnosis of prostate cancer. MATERIALS AND METHODS: A total of 330 consecutive patients suspected of having prostate cancer due to either abnormal digital rectal examination or elevated serum PSA levels underwent transrectal ultrasonography-guided sextant biopsy of the prostate. The PSA and PSAD values were assessed based on the biopsy results. RESULTS: One hundred and twenty-one patients (36.7%) had prostate cancer. In this group, the mean PSA was 31.60 +/- 30.85 ng/mL (range, 1.9 ng/mL to 166.0 ng/mL) and the mean PSAD was 0.83 +/- 1.01 (range, 0.04 ng/mL/cm3 to 6.38 ng/mL/cm3). In those without prostate cancer the mean PSA and PSAD levels were 13.80 +/- 18.72 ng/mL (range, 0.4 ng/mL to 130.0 ng/mL; P < .001) and 0.24 +/- 0.32 (range of 0.01 ng/mL/cm3 to 2.29 ng/mL/cm3; P < .001). The receiver operating characteristic curve analysis revealed that the discriminating power of serum PSA for detecting prostate cancer, as estimated by the area under the curve, was 0.74 while that for PSAD was 0.81 (P < .001). For the PSA range of 3.5 ng/mL to 41 ng/mL (gray zone) the areas under the curve was 0.68 for PSA, while it was 0.78 for PSAD (P < .001). CONCLUSION: The use of PSAD instead of PSA in the diagnosis of prostatic cancer improves the diagnostic accuracy. [ABSTRACT FROM AUTHOR]

Healing diabetic ulcers with chronic inflammation is a major challenge for researchers and professionals, necessitating new strategies. To rapidly treat diabetic wounds in rat models, we have fabricated a composite scaffold composed of alginate (Alg) and silk fibroin (SF) as a wound dressing that is laden with molecules of lithium chloride (LC). The physicochemical, bioactivity, and biocompatibility properties of Alg-SF-LC scaffolds were investigated in contrast to those of Alg, SF, and Alg-SF ones. Afterward, full-thickness wounds were ulcerated in diabetic rats in order to evaluate the capacity of LC-laden scaffolds to regenerate skin. The characterization findings demonstrated that the composite scaffolds possessed favorable antibacterial properties, cell compatibility, high swelling, controlled degradability, and good uniformity in the interconnected pore microstructure. Additionally, in terms of wound contraction, re-epithelialization, and angiogenesis improvement, LC-laden scaffolds revealed better performance in diabetic wound healing than the other groups. This research indicates that utilizing lithium chloride molecules loaded in biological materials supports the best diabetic ulcer regeneration in vivo, and produces a skin replacement with a cellular structure comparable to native skin., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest., (Copyright © 2024.

Male infertility can be caused by genetic anomalies, endocrine disorders, inflammation, and exposure to toxic chemicals or gonadotoxic treatments. Therefore, several recent studies have concentrated on the preservation and restoration of fertility to enhance the quality of life for affected individuals. It is currently recommended to biobank the tissue extracted from testicular biopsies to provide a later source of spermatogonial stem cells (SSCs). Another successful approach has been the in vitro production of haploid male germ cells. The capacity of SSCs to transform into sperm, as in testicular tissue transplantation, SSC therapy, and in vitro or ex vivo spermatogenesis, makes them ideal candidates for in vivo fertility restoration. The transplantation of SSCs or testicular tissue to regenerate spermatogenesis and create embryos has been achieved in nonhuman mammal species. Although the outcomes of human trials have yet to be released, this method may soon be approved for clinical use in humans. Furthermore, regenerative medicine techniques that develop tissue or cells on organic or synthetic scaffolds enriched with bioactive molecules have also gained traction. All of these methods are now in different stages of experimentation and clinical trials. However, thanks to rigorous studies on the safety and effectiveness of SSC-based reproductive treatments, some of these techniques may be clinically available in upcoming decades.

The research focused on analyzing the UGT gene family in Cannabis sativa , which plays a crucial role in the plant's metabolism and glycosylation of secondary metabolites. The study identified 125 UGTs using conserved plant secondary product glycosyltransferase (PSPG) motif amino acid sequences. These UGT genes were categorized into 17 groups (A-Q) through phylogenetic analysis, showing their distribution across 10 chromosomes in C. sativa . The expansion of the CsUGT gene family was attributed to tandem and duplication events, as suggested by gene duplication analysis. Furthermore, the study found various cis-acting regulatory elements related to phytohormones and stress responses in CsUGT promoter regions. Subcellular localization analysis revealed that CsUGT is present in the cytoplasm, chloroplast, and nucleus. The study revealed that CsUGT plays a significant role in various biological processes, cellular components, and molecular functions as highlighted by Gene Ontology analysis. Additionally, the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that some CsUGTs are associated with the biosynthesis of secondary metabolites. This research provides valuable insights into the genomic organization, evolutionary history, and potential regulatory mechanisms of UGT genes in C. sativa . It lays the foundation for further exploration of their specific biological roles and potential applications in the plant's metabolism and stress responses. These findings contribute to a better understanding of the UGT gene family and its relevance to the metabolic pathways in C. sativa ., Supplementary Information: The online version contains supplementary material available at 10.1007/s13205-024-04025-3., Competing Interests: Conflict of interestThe authors declare no conflict of interest., (© King Abdulaziz City for Science and Technology 2024.

Background: The motivation of caregivers plays a crucial role in the treatment, follow-up, and care of children with intellectual and developmental disabilities. Previous studies have focused on the older people and end-stage diseases, while giving less attention to the motivation of mothers caring for children with special needs. This study aimed to explore the motivations of mothers caring for children with intellectual and developmental disabilities in Iran., Methods: This study employed a qualitative approach, guided by the Self-Determination Theory. Purposeful sampling was initially used, followed by theoretical sampling until data saturation was achieved. Data were collected through semi-structured interviews with 26 mothers of children with intellectual and developmental disabilities. Mayring's seven-step directed content analysis approach was utilized for coding and categorization. The research adhered to ethical standards and ensured data trustworthiness through credibility, dependability, confirmability, and transferability measures., Results: The findings revealed that mothers' caregiving motivations could be classified into four main categories: (I) intrinsic, (II) identified-extrinsic, (III) introjected-extrinsic, and (IV) external-extrinsic. Additionally, twelve sub-categories were identified within these four main categories., Conclusion: The findings revealed that mothers demonstrated varying levels of intrinsic and extrinsic motivations in caring for children with intellectual and developmental disabilities. By recognizing and enhancing the diverse sources of motivation, healthcare providers and policymakers can better support mothers in their caregiving roles, ultimately contributing to improved outcomes for both the mothers and their children., (© 2024.

Background: Postpartum Hemorrhage (PPH) is a significant problem that can increase the risk of maternal mortality. Previous studies investigated the effect of Inhaled Oxygen (IO) on PPH. They found some conflicting results. Thus, the current systematic review and meta-analysis aimed to determine the effect of IO on PPH., Materials and Methods: Randomized trials were searched according to the PRISMA framework until the end of November 2022 in Web of Science, PubMed, Scopus, and Cochrane Library databases. Statistical analyses were performed in the STATA v. 14 software. I 2 statistic was applied to assess heterogeneity between studies. The random effect model, sample size, and mean and standard deviation of each group were applied to report the pooled effect size. Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) was used to evaluate the risk of bias in the included studies. Finally, five articles were included in the meta-analysis. Two and three studies reported the mean of bleeding after vaginal delivery during one- and two-hours oxygen therapy, respectively., Results: Results showed that IO significantly reduced bleeding by 38.91 mL in the intervention group compared to routine care (WMD: -38.91, 95%CI: -60.18 to -17.64) after vaginal delivery. In addition, IO during one (WMD: -38.42, 95%CI: -71.62 to -5.22) and two (WMD: -41.93, 95%CI: -60.15 to - 23.71) hours significantly decreased bleeding in the intervention., Conclusion: According to the present study, IO can significantly reduce PPH in the intervention group compared to routine care. However, more rigorously randomized clinical trials are required to decide better about this issue., Competing Interests: Nothing to declare., (Copyright: © 2024 Iranian Journal of Nursing and Midwifery Research.)

This systematic review and meta-analysis aimed to summarize the randomized clinical trial studies regarding the effects of Valsalva maneuver on the severity of short peripheral cannula insertion pain and hemodynamic status in adults. A systematic search was conducted on PubMed, Web of Science, Scopus databases, Cochrane, ClinicalTrials.gov, and Google Scholar Search Engine using keywords extracted from Medical Subject Headings, such as "Valsalva Maneuver," "Valsalva's Maneuver," "Forced Expiratory," "Balloon Inflation," "Pain," "Ache," "Cannulation," "Peripheral Intravenous Cannulation," "Peripheral Catheterization," "Vascular Access," "Venous Cannulation," "Venous Catheterization," and "Catheterization," from the inception to January 1, 2022. Finally, 12 and 11 articles were included in the qualitative and quantitative analysis of this systematic review and meta-analysis, respectively. Overall, pain intensity based on both the Numeric Rating Scale and Visual Analog Scale resulted in a large clinical effect (Effect Size: -1.20, 95% Confidence Interval: -1.69 to -0.71, p  < 0.001). A large clinical effect was observed in a separate study of both scales because clinical effect has been determined in studies based on the Numeric Rating Scale (Effect Size: -1.26, 95% Confidence Interval: -1.90 to -0.62, p  < 0.001 (and Visual Analog Scale (Effect Size: -1.09, 95% Confidence Interval: -1.98 to -0.20, p  = 0.016). Valsalva maneuver significantly increased the mean heart rate (Weighted Mean Difference: 1.90, 95% Confidence Interval: 1.56-2.24, p  < 0.001), decreased the mean arterial pressure (Weighted Mean Difference: 0.73, 95% Confidence Interval: -0.13 to 1.60, p  = 0.096), and caused a non-significant decrease in anxiety (Weighted Mean Difference: -1.95, 95% Confidence Interval: -5.24 to 1.34, p  = 0.25). The results showed that Valsalva maneuver significantly reduced pain intensity. Therefore, it is recommended that nurses use it as a convenient and low-cost non-pharmacological intervention to alleviate the severity of pain in non-cardiac patients. Also, it is suggested to conduct the studies with a strong methodological design and consider its effects on hemodynamic parameters in future investigations., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Previous studies have compared various technology-based devices, such as ultrasonography (USG), near-infrared (NIR), and transilluminator (TI), with standard care (SC) to facilitate peripheral intravenous cannulation (PIVC) in pediatric patients. This study aims to investigate the efficacy of these interventions on the first-attempt success rate (FASR) of PIVC in pediatric patients with difficult intravenous access (DIVA) using network meta-analysis (NMA)., Methods: We conducted a comprehensive literature search in databases to identify randomized clinical trials comparing the effects of different devices on the FASR of PIVC from inception until August 2023. Pooled relative risks with 95% credible intervals were estimated using pairwise and network meta-analysis with random effects. To rank the efficacy of devices, we calculated the probabilities of the surface under the cumulative ranking curve (SUCRA)., Results: A total of 18 studies were included in the final analysis. The results of pairwise meta-analysis showed that the use of devices increased the FASR for PIVC by 13% (RR: 1.13, 95% CI: [0.98, 1.30]) compared to SC. The ranking of interventions based on efficacy from highest to lowest was as follows: USG (SUCRA: 1), NIR (SUCRA: 0.6), SC (SUCRA: 0.3), and TI (SUCRA: 0.1), with a very low confidence estimate., Conclusion: Based on our findings, the prioritization of device usage to increase the FASR of PIVC in pediatric patients with DIVA is as follows: USG, NIR, SC, and TI, respectively. However, due to inconsistencies in the network, existence of an overall high risk of bias in the included studies, and very low confidence estimate, further clinical trials are required., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Peripheral venous catheter placement (PVCP) is difficult for children due to the small diameter of their veins in adipose tissue. The transilluminator device (TD) is proposed as the effective method for PVCP. Therefore, this meta-analysis aimed to assess the effect of TD on first attempt success rate (FASR), mean the number of attempts (MNA), and mean duration of successful PVC placement (MDSPP) in children. In a systematic review and meta-analysis, an extensive search of online databases including PubMed, Scopus, Science Direct, Web of sciences, Cochrane, Clinical trial.gov, ProQuest, and Google scholar search engine was conducted. Keywords were combined and searched from the earliest records up to December 2021. The current meta-analysis was performed using STATA V.14.0 software. Six studies (four RCTs and two non-RCTs design) were included in the present meta-analysis. Analysis showed using of TD significantly led to FASR to 34% in studies with RCTs design (RR = 1.34; CI = 1.18-1.53) although, non-RCT studies did not indicate it (RR: 0.95; CI = 0.50-1.79). Also, one RCT (WMD = -0.24; CI = -0.4 -0.08) and two non-RCTs 0.05 (WMD = -0.05; 95% CI = -0.46-0.37) reported the MNA. Two RCTs (WMD: -24.30; CI = -53.50-4.89) and one non-RCT (WMD: -295.20; CI = -359.34 to -231.06) found TD decreased MDSSP. RCTs and non-RCTs studies showed different results in terms of some outcomes. Based on the results of four RCTs studies, the use of TD significantly increased the FASR of PVCP. The results of two non-RCTs also showed TD insignificantly decreased the FASR of PVCP. More evidence (RCT design) is required for decision-making about the effectiveness of TD on successful PVCP., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The present study attempted to evaluate the effect of oral gabapentin and acetaminophen for postoperative analgesia in anorectal surgery., Methods: This double-blind clinical trial was carried out on 144 patients who were candidates for anorectal surgery. The patients were randomly assigned into three groups of control, acetaminophen 500 mg, and gabapentin 300 mg for two hours before the surgery. Data on pain severity based on the visual analog scale (VAS) were evaluated and analyzed., Results: The results of the current study indicated that in patients taking acetaminophen and gabapentin tablets before surgery, the amount of postoperative pain decreased, and the amount of decrease in postoperative pain in the patients who received acetaminophen and gabapentin tablets compared with the placebo group was significant ( P <0.001). Also, an evaluation was done using a proposed fuzzy logic model., Conclusion: Taking acetaminophen and gabapentin tablets one hour before the operation causes a significant reduction in postoperative pain in patients who are candidates for anorectal surgery. The results are promising and encourage one to pay attention to more studies with the goal of possibly using them as a decision-support model in the future., Competing Interests: Competing Interests The authors declare no conflict of interest related to this work., (© 2024 Middle East Journal of Digestive Diseases.)

Aim: Cu 2 O nanoparticles were synthesized using an extract from S. latifolium algae (SLCu 2 O NPs). Their effect on PANC-1 cells and the expression of two drug resistance-related lncRNAs were evaluated in comparison with Arsenic trioxide. Materials & methods: SLCu 2 O NPs were characterized using XRD, SEM, and TEM microscopies. The effects of SLCu 2 O NPs on cell cytotoxicity, cell cycle, and apoptosis, and expression of two drug resistance-related lncRNAs were examined using MTT assay, flow cytometry, and real-time PCR, respectively. Results: SLCu 2 O NPs demonstrated anti-cancer properties against PANC-1 cells comparable to Arsenic trioxide, and the expression of lncRNAs increased upon treatment with them. Conclusion: SLCu 2 O NPs demonstrate anti-cancer properties against PANC-1 cells; however, using gene silencing strategies along with SLCu 2 O NPs is suggested.

Introduction: Pain experienced during the insertion of a catheter into the arteriovenous fistula (AVF) and restless legs syndrome (RLS) are prevalent issues among Hemodialysis (HD) patients. The primary objective of this systematic review and meta-analysis was to consolidate the findings from randomized clinical trial (RCT) studies examining the impact of aromatherapy with lavender on the pain associated with AVF catheter insertion and RLS in HD patients., Methods: A systematic search was conducted on PubMed, Web of Science, Scopus, Cochrane, Embase, ClinicalTrials.gov, and Google Scholar search engine from inception to August 1, 2022, using keywords extracted from Medical Subject Headings, such as "Aromatherapy", "Lavender", "Arteriovenous fistula", "Pain", "Restless legs syndrome", and "Hemodialysis"., Results: Finally, eleven articles were included in this systematic review and meta-analysis. The results showed that aromatherapy reduced the average pain of catheter insertion in AVF compared to the control group (Standard Mean Difference: -1.60, 95% Confidence Interval: -2.32 to -0.87, Z=4.32, I 2 :90.3%, P<0.001). Also, aromatherapy massage reduced the average severity of RLS compared to the control group, which was statistically significant (Weighted Mean Difference: -13.21, 95% Confidence Interval: -17.50 to -8.91, Z=6.03, I 2 :93.0%, P<0.001). Also, the subgroup analysis showed that lavender in the intervention group significantly decreased the pain intensity compared to the "no intervention" group (P<0.001), yet it was not significant compared to the placebo group (P=0.12)., Conclusion: In summary, the findings indicate a notable reduction in catheter insertion pain in AVF and relief from RLS among HD patients through the use of lavender essential oil. As a result, future research is encouraged to include a comparison of lavender's effects with those of a placebo group., Competing Interests: The authors declare that there is no conflict of interest.

Non-accidental burns (NABs) in children had some adverse effects, such as severe burns, requiring skin grafting, and mortality. Previous studies reported NABs in the form of neglect, suspected abuse, and child abuse. Also, different statistics were estimated for the prevalence of NABs in children. Therefore, the current study aimed to comprehensively review and summarise the literature on the prevalence of NABs in children. Also, factors related to NABs as a secondary aim were considered in this review. Keywords combined using Boolean operators and searches were performed in international electronic databases, such as Scopus, PubMed, and Web of Science. Only studies in English were considered from the earliest to 1 March 2023. The analysis was performed using STATA software version 14. Finally, 29 articles were retrieved for the quantitative analysis. Results found that the prevalence of child abuse, suspected abuse, neglect, 'child abuse or suspect abused', and 'abuse, suspect abused, or neglect' was 6% (ES: 0.06, 95% confidence interval [CI]: 0.05-0.07), 12% (ES: 0.12, 95% CI: 0.09-0.15), 21% (ES: 0.21, 95% CI: 0.07-0.35), 8% (ES: 0.08, 95% CI: 0.07-0.09), and 15% (ES: 0.15, 95% CI: 0.13-0.16) among burns victims, respectively. Also, factors related to NABs are categorised into age and gender, agent and area of burns, and family features. Considering the results of the current study, planning for rapid diagnosis and designing a process to manage NABs in children is necessary., (© 2023 The Authors.

Burn injuries, as a major public health problem, can lead to high morbidity and mortality. Burns is considered as one of the most devastating injuries globally and the fourth most common injury after traffic accidents, falls and interpersonal violence. Burn injuries can affect human life, such as physical and mental health, functional skills, and performance. Changes in appearance, social isolation, stress, anxiety, depression, low self-esteem, unemployment, financial burden and family problems can occur in these patients. These burn complications can be exacerbated without adequate social support. This systematic review evaluated burn patients' social support and related factors. A systematic search was performed on the international electronic databases such as Scopus, PubMed, Web of Science and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Burns', 'Social support', 'Perceived social support' and 'Social care' from the earliest to 30 April 2022. The quality of the included studies in this review was assessed using the appraisal tool for cross-sectional studies (AXIS tool). A total of 1677 burn patients were included in this review from 12 studies. Mean score of social support in burn patients based on multidimensional scale of perceived social support, Phillips's social support questionnaire, social support questionnaire, social support scale and Norbeck social support questionnaire were 5.04 (SD = 1.59) of 7, 22.06 (SD = 3.05), 78.20 (SD = 15.00) of 95, 82.24 (SD = 13.70) and 4.14 (SD = 0.99), respectively. Factors such as income, educational attainment, burn surface area, reconstructive surgery, quality of life, self-esteem, socialisation, posttraumatic growth, spirituality, and ego resilience had a significant positive relationship with social support of burns patients. Social support in patients with burn had a significant negative relationship with factors such as psychological distress, having children, life satisfaction, neuroticism and post-traumatic stress disorder. Overall, patients with burns had moderate levels of social support. Therefore, it is recommended that health policymakers and managers make it easier for burn patients to adapt to burns by providing psychological intervention programs and the social support needed by burn patients., (© 2023 The Authors.

This systematic review aimed to examine the knowledge of caregivers regarding pressure ulcer (PU) prevention. A thorough, methodical search was conducted from the earliest date to February 1, 2023 using keywords extracted from Medical Subject Headings such as "Caregivers", "Knowledge", and "Pressure ulcer" in various international electronic databases such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex and Scientific Information Database. The quality of the studies included in this systematic review was evaluated using an appraisal tool for cross-sectional studies (AXIS tool). In total, 927 caregivers participated in the eight studies. The average age of the participants was 40.50 (SD = 12.67). Among the participants, 61.87% were women. The average caregiver's knowledge of PU prevention was 53.70 (SD = 14.09) out of 100, which suggests a moderate level of knowledge. Factors such as level of education, age, occupation, information about PUs, attitude, and practice had a significant positive relationship with caregivers' knowledge related to the prevention of PUs. Knowledge had a significantly negative relationship with age. In addition, marital status, type of relationship, age, gender, occupation, level of education, and inpatient wards had a significant relationship with caregivers' knowledge regarding PUs prevention. Therefore, managers and policymakers in the medical field can help increase caregivers' knowledge by providing an online or in-person educational platform relevant to PU prevention., (© 2023 The Authors.

This systematic review aims to examine the knowledge of medical science students about burn first aid. A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Knowledge", "First aid", "Medical science student" and "Burn" from the earliest to February 1, 2023. The quality of the studies included in this systematic review was evaluated by using the appraisal tool for cross-sectional studies (AXIS tool). Thirteen studies had a total of 5046 students studying medical sciences. Among them, 62.24% were female and 77.67% were medical students. The studies included in this systematic review were conducted in Saudi Arabia, Pakistan, Syria, Egypt, and Malaysia. Medical science students' average knowledge of first aid for burns is 56.92 out of 100, which is considered to be a moderate level of knowledge. Factors such as the experience of first aid training, academic year, clinical experience, and economic status had a significant positive relationship with the knowledge of medical science students about first aid for burns. Also, factors such as age, academic specialisation, academic year, information sources, and fathers' occupation had a significant relationship with the knowledge of medical students about first aid for burns. Therefore, it is suggested that healthcare managers and policymakers make the necessary plans to ensure that first aid training courses are implemented during medical science students' studies as a part of their curriculum., (© 2023 The Authors.

The purpose of this review study is to investigate the attitude of nursing students toward the prevention of pressure ulcers (PUs) and related factors. From February 1, 2023, a comprehensive search was conducted in international and Persian electronic databases such as Web of Science, PubMed, Scopus, Iranmedex, and Scientific information database (SID). The keywords obtained from Medical Subject Headings, including "Attitude", "Nursing students", and "Pressure ulcer" were used in this search. The quality assessment of the present studies in this systematic review was based on the appraisal tool for cross-sectional studies (AXIS tool). A total of 6454 nursing students participated in ten cross-sectional studies. All students were studying at the undergraduate level and 81.20% of them were female. Nursing students were in the first (39.27%), second (28.19%), and third and fourth (32.54%) academic years. Among the participants, 49.86% have completed at least 2 clinical units. The mean scores of attitudes toward PU prevention in nursing students based on attitude toward PU prevention (APuP) and researcher-made questionnaires were 75.01% and 68.82%, respectively. The attitude of nursing students was influenced by various factors, including age, sex, academic year, clinical experience, number of clinical units, experience in caring for PU patients, previous courses on PU in the curriculum, and contribution of training to knowledge. Also, in the present study, the positive relationship between the attitude and knowledge of nursing students was shown as the only significant correlation. In sum, the attitude of the majority of nursing students toward the prevention of PUs was at a satisfactory level. Therefore, it is expected to transfer the necessary knowledge to them with proper planning so that preventive actions can be carried out by following the guidelines., (© 2023 The Authors.

Perceived stigmatisation (PS) can cause different effects on burns survivors such as depression, low self-esteem, body image disturbance, and social anxiety. Current systematic review and meta-analysis aimed to determine the average PS among the burns survivor population and the average reliability of the PS questionnaire (PSQ). A comprehensive systematic search was conducted in various international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Stigmatisation", "Burns", "Reliability", and "Questionnaire" from the earliest to February 1, 2023. The COSMIN and the Joanna Briggs Institute (JBI) checklists were applied to evaluate the risk of bias. Data analysis was performed in STATA V.14 and JAMOVI v 2.3.24 software. The analysis consisted of two sections. Firstly, the overall weighted average of PS was calculated based on mean and standard deviation. Then, the reliability average of PSQ was calculated with the reliability generalisation method based on the alpha coefficient, questionnaire items, and sample size of each study. Finally, eight articles were included in the quantitative analysis. The results showed the weighted average of PS was 2.14 (ES: 2.14, 95%CI: 1.77-2.51, Z = 11.40, I 2 :97.8%, P < 0.001). The average of PS in the factors of confused/staring behaviour, absence of friendly behaviour, and hostile behaviour was 2.36 (ES: 2.36, 95%CI: 2.05-2.67, Z = 14.86, I 2 :92.7%, P < 0.001), 2.13 (ES: 2.13, 95%CI: 1.87-2.39, Z = 16.22, I 2 :93.8%, P < 0.001) and 2.07 (ES: 2.07, 95%CI: 1.67-2.47, Z = 10.05, I 2 :96.5%, P < 0.001), respectively. The analysis showed that the overall coefficient alpha of the PSQ was 0.88 (ES: 0.88, 95%CI: 0.851-0.910, Z = 58.7, I 2 : 95.04%, P < 0.001). Also, the alpha coefficient of factors including confused/staring behaviour, absence of friendly behaviour, and hostile behaviour were 0.847 (ES: 0.847, 95%CI: 0.770-0.924, Z = 21.6, I 2 :99.13%, P < 0.001), 0.860 (ES: 0.860, 95%CI: 0.808-0.912, Z = 32.4, I 2 :98.02%, P < 0.001) and 0.899 (ES: 0.899, 95%CI: 0.829-0.968, Z = 21.33, I 2 : 0.0%, P < 0.001), respectively. In sum, the current study showed that the average PS was 2.14 out of 5 points. Most survivors and parents reported confused/starring behaviour as a common perceived behaviour from different individuals. Also, the average reliability of PSQ was 0.88, and it had acceptable reliability. More studies are required to better judge the level of PS among different age groups. Also, the psychometric properties of PSQ in different cultures are an essential issue., (© 2023 The Authors.

The present systematic review was conducted to investigate the knowledge of health care workers (HCWs) regarding first aid in burns. A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Knowledge', 'First aid', 'Health personnel' and 'Burns' from the earliest to 1 February 2023. The appraisal tool for cross-sectional studies (AXIS tool) evaluates the quality of the included studies. A total of 3213 HCWs participated in seven cross-sectional studies. Of the HCWs, 44.50% were physicians. The studies included in this systematic review were conducted in Saudi Arabia, Australia, Turkey, the UK, Ukraine, and Vietnam. The knowledge rate of HCWs related to first aid for burns was 64.78 out of 100, which indicates their relatively desirable knowledge. The factors of first aid training experience, age, and experienced burn traumas had a significant positive effect on the knowledge of HCWs related to first aid for burns. Also, factors such as gender, nationality, marital status, and job position had a significant relationship with the knowledge of HCWs about first aid for burns. Therefore, it is suggested that health care managers and policymakers implement training programs and practical workshops related to first aid, especially first aid for burns., (© 2023 The Authors.

Introduction: Patient satisfaction (PS) with nursing care is considered one of the most important predictors of satisfaction with hospital services. The current research was conducted to determine the level of PS with nursing care provided in hospitals in Iran., Methods: A comprehensive systematic search was conducted in various international electronic databases, such as PubMed, Scopus, Web of Science, and Persian electronic databases such as Iranmedex, and the Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as 'Patient satisfaction', 'Satisfaction', 'Nursing care', and 'Nurse' from the earliest to 27 January 2023. The risk of bias was assessed using the Joanna Briggs Institute (JBI) scale, and the analysis was performed in Stata software version 14. Subgroup and sensitivity analyses were performed to clarify the source of heterogeneity., Results: The results showed that the overall PS with nursing care in different hospitals was 0.83 (95% CI: 0.79-0.86). The proportions of complete satisfaction, partial satisfaction, and dissatisfaction were 0.38 (95% CI: 0.23-0.53), 0.45 (95% CI: 0.34-0.55), and 0.17 (95% CI: 0.12-0.21), respectively., Conclusion: However, overall satisfaction was seen in four out of five patients admitted to hospitals in Iran, complete satisfaction with nursing care was 38%. Future studies should identify the effective factors related to PS with nursing care., Competing Interests: The author(s) declares(s) that there is no conflicts of interest., (Copyright © 2023 The Author(s).

This systematic review aimed to examine the life satisfaction and related factors among burns patients. A comprehensive systematic search was conducted at the international electronic databases such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Burns', 'Life satisfaction', 'Personal satisfaction', and 'Patient satisfaction' from the earliest to the 1 October 2022. The quality of the studies included in this review was evaluated using the appraisal tool for cross-sectional studies (AXIS tool). A total of 3352 burn patients in the nine cross-sectional studies were included in this systematic review. 70.52% of burn patients were male. The mean age of burn patients was 37.47 (SD = 14.73). The mean score of life satisfaction in burn patients based on SWLS was 23.02 (SD = 7.86) out of 35, based on LSI-A was 12.67 (SD = 4.99) out of 20, and based on the life satisfaction questionnaire was 4.81 (SD = 1.67) out of 7. Factors including time since burn, religion, and constant had a positive and significant relationship with life satisfaction in burn patients. Whereas, factors such as single marital status, age at injury, length of hospital stay, presence of pain, larger total body surface area burn, head and neck burn, functional impairment, family satisfaction, satisfaction with appearance, and previous psychiatric treatment had a negative and significant relationship with life satisfaction in burn patients. In sum, this systematic review showed that burn patients were slightly satisfied with their life. Therefore, health managers and policymakers can improve the quality of life of burn victims by planning psychological counselling and behavioural therapy, and consequently increase their life satisfaction., (© 2023 The Authors.

The aim of this review study is to investigate the nurses' knowledge and related factors towards the prevention of medical device-related pressure ulcers (MDRPUs). An extensive search was conducted in international electronic databases such as PubMed, Web of Science, and Scopus, and Persian databases, such as Iranmedex and the Scientific Information Database from December 1, 2022. During this search, keywords extracted from Medical Subject Headings, such as "Prevention knowledge," "Nurse," "Pressure ulcer," "Equipment and Supplies," and "Intensive Care Units" were used. The quality of the present studies in this review was evaluated based on the appraisal tool for cross-sectional studies (AXIS tool). A total of 1847 nurses participated in this review from five studies, and the majority of them (82.94%) were female. The mean age of the participants was 31.40 (SD = 5.97). The mean score of MDRPUs prevention knowledge in nurses based on PU2014 scale and researcher-made questionnaires were 16.50 (SD = 3.74) out of 31 and 65.49 (SD = 6.33) out of 100, respectively. The knowledge of nurses is influenced by factors such as age, sex, level of education, work experience, technical titles, type of hospital, level of hospital, and type of ward. Various factors had a significant positive relationship with nurses' MDRPUs prevention knowledge, which includes level of education, work experience, previous training on MDRPU, having a wound care certificate, an online search about MDRPU, and attitude and practise towards MDRPU prevention. At the same time, nurses' knowledge about the prevention of MDRPUs had a significant negative relationship with the time interval since last participating in MDRPU training or workshop. Overall, the level of MDRPUs prevention knowledge among nurses was insufficient to moderate. Therefore, it is suggested to provide facilities for nurses to receive the necessary training., (© 2023 The Authors.

This systematic review aimed to examine the caregivers' knowledge with burned children and related factors towards burn first aid. A comprehensive, systematic search was performed in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as "Knowledge", "First aid", "Caregiver", "Burn", and "Child" from the earliest to the December 1, 2022. The quality of the studies included in this systematic review was evaluated by using the appraisal tool for cross-sectional studies (AXIS tool). A total of 11 763 caregivers of children with burns were enrolled in 14 studies. Of the participants, 78.81% were female and 41.15% had a university education. The mean score of caregivers' knowledge with burned children towards burn first aid was 51.44 out of 100. The knowledge of caregivers of burned children towards burn first aid had a significant positive relationship with the level of education, first aid training, age of caregivers, history of burn, number of children, monthly income, social status, and attitude. In addition, caregivers' knowledge had a significant negative relationship with the number of children. Furthermore, there was a significant relationship between caregivers' knowledge and level of education, monthly income, smoking, and previous knowledge of first aid. The level of caregivers' knowledge with burned children towards burn first aid was moderate. Therefore, health managers and policymakers can improve the knowledge of caregivers of burned children towards burn first aid by creating suitable platforms for face-to-face training as well as online training using websites., (© 2023 The Authors.

Pain is one of the complications associated with burns, which can lead to anxiety and sleeplessness in children. Various studies evaluated the effects of non-pharmacological interventions on burn wound care. The present study was conducted to determine the effects of non-pharmacological interventions on pain intensity of children with burns. A comprehensive systematic search was conducted in various international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Non-pharmacological', 'Virtual reality', 'Pain', 'Burn', 'Wound' and 'Child' from the earliest to December 1, 2022. The risk of bias in the final articles was also assessed with the Version 2 of the Cochrane risk-of-bias tool for randomised trials (RoB 2). Finally, a total of 1005 burn patients were included in 19 studies. The age range of the patients was from 0.5 to 19 years. Of the participants, 50.05% were in the intervention group. All studies had a randomised clinical trial design. The results found that non-pharmacological interventions significantly reduced pain intensity in children (ES: -0.73, 95% CI: -1.08 to -0.38, Z = 4.09, I 2 :79.8, P < .001). Virtual reality (VR) (ES: -0.54, 95% CI: -1.19 to -0.18, Z = 2.90, I 2 :72.9%, P = .004) and non-VR (ES: -0.86, 95% CI: -1.45 to -0.27, Z = 2.86, I 2 :91.4%, P = .04) interventions decreased pain intensity significantly in children based sub-group analysis. Non-pharmacological interventions significantly reduced the pain intensity of dressing removal (ES: -0.77, 95% CI: -1.34 to -0.20, Z = 66.3, I 2 :91.8%, P = .008), dressing application (ES: -0.53, 95% CI: -0.97 to -0.09, Z = 2.37, I 2 :60.8%, P = .02), and physical therapy (ES: -1.18, 95% CI: -2.10 to -0.26, Z = 2.51, I 2 :88.0%, P = .01). Also, interventions reduced the pain of burn wound care (ES: -0.29, 95% CI: -1.01 to 0.44, Z = 0.78, I 2 :72.6%, P = .43), but it was statistically insignificant. In sum, the result of the present study indicated that using non-pharmacological interventions significantly reduced pain intensity in children. The reduction of pain intensity was greater in non-VR than in VR interventions. Future studies should focus on comparing VR interventions with non-VR and single versus multi-modal distraction to clarify the effectiveness of each., (© 2023 The Authors.

The aim of this systematic review and meta-analysis is to provide an overview of the prevalence of pressure ulcers (PU) in orthopaedic wards. A comprehensive, systematic search was conducted in different international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database (SID) using keywords extracted from Medical Subject Headings such as "Prevalence", "Pressure ulcer", "Pressure sore", and "Orthopaedics" from the earliest to February 1, 2023. The appraisal tool for cross-sectional studies (AXIS tool) evaluates the quality of the included studies. Finally, 11 studies were included in the final analysis. The results indicated that the prevalence of PU in orthopaedic departments was 18% (ES: 0.18, 95% CI: 0.10-0.26, Z = 4.53, I 2 : 99.09%). Although the odds ratio of PU was lower in men than women, it was not statistically significant (OR: 0.91, 95% CI: 0.74-1.11, Z = 0.95, I 2 : 17.4%, P = .34). Also, results showed the prevalence of PU was higher among studies with a sample size of more than 200 (ES: 0.19, 95% CI: 0.10-0.28, Z = 4.07, I 2 : 99.1%), Europe region (ES: 0.20, 95% CI: 0.14-0.26, Z = 6.7, I 2 : 93.0%) and prospective design (ES: 0.23, 95% CI: 0.18-0.27, Z = 9.47, I 2 : 83.3%) when compared with other sub-groups. In sum, considering the 18% prevalence of PU in the orthopaedic department, it is recommended to focus on detecting risk factors and design interventions to reduce PU in the patients admitted orthopaedic department., (© 2023 The Authors.

This systematic review and meta-analysis aim to summarise the effect of breathing exercise techniques (BET) on the pain and anxiety of burn patients during burn care. A systematic search was performed on international electronic databases such as Scopus, PubMed, and Web of Science, as well as on Iranian electronic databases such as Iranmedex and Scientific Information Database (SID) with keywords extracted from Medical Subject Headings such as 'Burns', 'Bandages', 'Pain', 'Pain management', 'Anxiety', 'Breathing', and 'Breathing exercise', which were performed from the earliest to 4 April 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist assessed the quality of randomised control trials (RCTs) and quasi-experimental studies. The current meta-analysis was performed using STATA V.14.0 software. A 95% confidence interval (CI) was used to determine significance levels. Random effect model was used to calculate the weighted mean difference (WMD). A total of 469 burn patients participated in 10 studies. Exactly 58.60% of burn patients were male, and the number of people in the intervention and control groups was equal. The mean age of burn patients was 32.84 (SD = 10.39). Exactly 78.05% of patients had second-degree burns. The mean study duration was 19 weeks. Results of analysis of RCT studies showed BET decreased insignificantly pain severity (WMD: -1.17, 95%CI: -2.54 to 0.21, Z = 1.66, P = .096, I 2 :97.1%) in the intervention group than control group. However, the results of non-RCTs studies indicated BET significantly decreased pain (WMD: -1.38, 95%CI: -2.16 to -0.61, Z = 3.49, P < .001, I 2 :88.4%) and anxiety (WMD: -4.91, 95%CI: -9.35 to -0.47, Z = 2.71, P = .03 0.001, I 2 :88.4%) in the intervention group than control group. Overall, the results of RCTs found BET intervention decreased pain in the intervention group when compared with the control group; however, it was statistically insignificant. Also, results of non-RCT studies showed intervention of BET significantly decreased pain and anxiety in burns patients. More RCTs studies are required for better judgement of the effectiveness of BET intervention in clinical settings., (© 2022 The Authors.

This systematic review and meta-analysis aimed to examine the effects of massage therapy on pain and anxiety intensity in patients with burns. A comprehensive, systematic search was conducted in various international electronic databases, such as Scopus, PubMed, Web of Science, and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Massage therapy', 'Musculoskeletal manipulations', 'Acute pains', 'Burning pain', and 'Burn' from the earliest to October 17, 2022. Cochran's tool is used to check the risk of bias for randomised clinical trial (RCT) articles. The methodological index for non-randomised studies was used to assess the risk of bias in quasi-experimental studies. STATA version 14 software was used to perform the meta-analysis. A 95% confidence interval (CI) was used to determine statistical significance. Heterogeneity was investigated with I 2 . A P-value less than .1 was considered statistically significant for publication bias value. A total of 733 patients with burns were included in seven studies. Five studies had an RCT design and two studies had a quasi-experimental design. The duration of the study was reported in five studies, with a mean of 42.40 weeks. The duration of the intervention was reported in seven studies with a mean of 22.86 minutes. The results of the meta-analysis showed using various types of massage therapy interventions significantly reduced pain intensity in the intervention group compared with the control group (weighted mean difference: -2.08, 95% CI: -2.55 to -1.62, Z = 8.77, I 2 : 67.1%, P < .001). Massage therapy intervention significantly reduced the intensity of anxiety in burn patients (standard mean difference: -7.07, 95% CI: -10.13 to -4.01, Z = 4.53, I 2 : 98.2, P < .001). Overall, the present systematic review and meta-analysis showed that massage therapy can reduce the intensity of pain and anxiety in burn patients. Therefore, it is recommended that health managers and policymakers pay special attention to massage therapy as a simple, low-cost, and efficient non-pharmacological treatment to relieve pain and anxiety in burn patients., (© 2023 The Authors.

Pain and anxiety were considered the most common complications of treatment procedures in burn patients. Non-pharmacological drugs, including aromatherapy, can decrease these issues. This systematic review and meta-analysis aim to summarise the effects of aromatherapy with Rosa damascene (RD) and lavender on the pain and anxiety of burn patients. A systematic search was performed on international electronic databases such as Scopus, PubMed, and Web of Science, as well as on Iranian electronic databases such as Iranmedex and Scientific Information Database (SID) with keywords extracted from Medical Subject Headings such as "Burns", "Pain", "Pain management", "Anxiety", and "Aromatherapy" were performed from the earliest to November 1, 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist assessed the quality of randomised control trials (RCTs) and quasi-experimental studies. STATA v.14 software was used to estimate pooled effect size. Heterogeneity was assessed with I 2 value. Random effect model and inverse-variance method using sample size, mean, and standard deviation changes were applied to determine standard mean differences (SMD). The confidence interval of 95% was considered to determine the confidence level. A total of 586 burn patients participated in six studies, including three RCT studies and three quasi-experimental studies. The results based on RCT studies showed RD significantly decreased the dressing pain average when compared to the control group (SMD: -1.61, 95%CI: -2.32 to -0.99, Z = 5.09, I 2 : 66.2%, P < 0.001). Aromatherapy with lavender decreased the average pain in the interventional group more than in the control group (SMD: -1.78, 95%CI: -3.62 to 0.07, Z = 1.89, I 2 : 97.2%, P = 0.06). Using aromatherapy with RD and lavender significantly decreased pain average in the interventional group than the control group (SMD: -1.68, 95%CI: -2.64 to -0.72, Z = 3.42, I 2 : 94.2%, P = 0.001). The results showed RD significantly decreased the anxiety average in the interventional group than the control group (SMD: -2.49, 95%CI: -2.98 to -2.0, Z = 9.94, I 2 : 51.6%, P < 0.001). Overall, this study showed that aromatherapy with RD decreased pain and anxiety of dressing procedures in burn patients. Although aromatherapy with lavender decreased pain in the patients, it was not statistically significant. More RCTs studies are required to be able to better judge the effects of aromatherapy with RD and lavender on the pain and anxiety of burn patients., (© 2023 The Authors.

Introduction: This systematic review and meta-analysis aimed to summarize the evidence regarding the impact of needle direction and distance of arteriovenous fistula (AVF) cannulation on KT/V (where k is the dialyzer urea clearance, t, the duration of dialysis, and V, the volume of distribution of urea) and access recirculation (AR) as hemodialysis (HD) adequacy criteria., Methods: A comprehensive systematic search was performed on international and domestic electronic databases from the earliest to June 4, 2022 using keywords. Analysis was performed in STATA software v.14., Results: Three randomized control trials (RCTs) and four non-RCT articles were included in the final review. Six studies reported the effects of direction, while four mentioned the effects of distances of AVF cannulation on outcomes of HD adequacy based on KT/V or AR. Results of three non-RCT studies showed that retrograde direction decreased KT/V more than antegrade direction (ES: 0.44, 95% CI: -0.38 to 1.27). Two non-RCT studies showed that antegrade decreased AR compared to the retrograde direction (ES: -0.64, 95%CI: -1.94 to 0.67). However, the results of two RCTs indicated uncertainty about this issue. Two of the four studies suggested that a distance of 5 cm or more in arterial and venous needles had greater adequacy than a distance of less than 5 cm. However, other studies did not confirm this finding., Conclusion: Overall comparison of the results qualitatively and quantitatively indicated uncertainty about the effects of direction and distance of AVF cannulation on HD adequacy outcomes. More studies with high-quality designs, such as RCTs, are required to better understand and adjudicate the effects of needle direction and distance of AVF cannulation on HD adequacy outcomes., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Ventilator-associated pneumonia (VAP) is one of the most common nosocomial infections affecting one-third of patients with mechanical ventilation. This study aimed to synthesize available evidence regarding the effect of treatment with povidone-iodine (PI) among adult patients admitted to intensive care units (ICUs) for the prevention of VAP., Methods: An extensive search was conducted in online databases, including PubMed, Web of Science and Scopus, from the earliest records until January 1, 2023. STATA software v14 was used for statistical analysis. Publication bias was assessed via funnel plot, Begg's and Egger's tests. A P-value less than 0.1 was considered statistically significant for publication bias value., Results: Four studies were included in the meta-analysis. Three studies showed rhat PI decreased VAP compared to the placebo group, but it was not statistically significant (RR: 0.61, 95%CI: 0.25 to 1.47, Z=1.10, P=0.27, I2:71.5%). One study compared the effect of PI with chlorhexidine on the rate of VAP, the difference between which was not statistically significant (RR: 1.50, 95%CI: 0.46 to 4.87, Z=0.67, P=0.50, I2:0). Two studies demonstrated that the use of PI intervention compared to placebo decreased the average length of stay in ICU; however, it was not statistically significant (WMD: -0.35, 95%CI:-3.90 to 3.20, Z=0.19, P=0.85, I2:0). Also, three studies showed that using PI had almost no effect on mortality rate compared to placebo (RR: 1.05, 95%CI: 0.66 to 1.53, Z=0.8, P=0.27, I2:29.0%)., Conclusion: More rigorously designed randomized clinical trials and further evidence are required to make a better decision/comparison about using PI as a suitable choice for preventing VAP among adult patients admitted to the ICU., Competing Interests: The authors declare no conflict of interest.

Saline stress is responsible for significant reductions in the growth of plants, and it globally leads to limitations in the performance of crops, especially in drought-affected areas. However, a better understanding of the mechanisms involved in the resistance of plants to environmental stress can lead to a better plant breeding and selection of cultivars. Mint is one of the most important medicinal plants, and it has important properties for industry, and for the medicinal and pharmacy fields. The effects of salinity on the biochemical and enzymatic properties of 18 ecotypes of mint from six different species, that is, Mentha piperita, Mentha mozafariani, Mentha rotundifolia, Mentha spicata, Mentha pulegium and Mentha longifolia, have been examined in this study. The experimental results showed that salinity increased with increasing in stress integrity influenced the enzymatic properties, proline content, electrolyte leakage, and the hydrogen peroxide, malondialdehyde, and essential oil contents. Cluster analysis and principal component analysis were conducted, and they grouped the studied species on the basis of their biochemical characteristics. According to the obtained biplot results, M. piperita and M. rotundifolia showed better stress tolerance than the other varieties, and M. longifolia was identified as being salt sensitive. Generally, the results showed that H 2 O 2 and malondialdehyde had a positive connection with each other and showed a reverse relationship with all the enzymatic and non-enzymatic antioxidants. Finally, it was found that the M. spicata, M. rotundifolia and M. piperita ecotypes could be used for future breeding projects to improve the salinity tolerance of other ecotypes., (© 2023 Wiley-VHCA AG, Zurich, Switzerland.)

Various pharmacological and non-pharmacological measures are used to reduce pain of patients on hemodialysis during an arteriovenous fistula (AVF) cannulation. In this randomized, crossover clinical trial, 39 patients randomly received acupressure and cryotherapy. In cryotherapy, an ice cube was used to massage the Hegu point in the hand without the fistula for 10 minutes before AVF cannulation. In acupressure, a moderate pressure with the thumb was applied. The pain score was mild after cryotherapy and acupressure, with no significant difference between the two methods. In addition, acupressure significantly reduced pain compared with routine care, but cryotherapy did not significantly reduce pain compared with routine care. Pain intensity was mild after acupressure and cryotherapy, and neither of these two methods was preferred over the other to reduce the pain during AVF cannulation., Competing Interests: The authors reported no actual or potential conflict of interest in relation to this nursing continuing professional development (NCPD) activity., (Copyright© by the American Nephrology Nurses Association.)

Novel coronavirus disease 2019 (COVID-19) as a potential health risk factor continues to spread worldwide. Although common symptoms include headache and respiratory symptoms, some studies have suggested that COVID-19 may cause coagulation disorders and thrombolytic events, disrupt blood flow to the visceral organs, and cause some complications such as mesenteric ischemia. The authors reported four cases of acute mesenteric ischemia associated with COVID-19 confirmed in patients hospitalized in Imam Reza Hospital (a COVID-19 referral center in Mashhad University of Medical Sciences, Mashhad, Iran). The authors described the pathological findings that may be associated with this infection. The authors collected clinical data, imaging, microscopic, and operative findings of four patients with severe COVID-19 infection and evidence of intestinal necrosis. These four cases of severe COVID-19 pneumonia simultaneously showed intestinal necrosis during the infection process, indicating a relationship between coronavirus and mesenteric vascular events. Physicians should be aware of thrombosis symptoms in the digestive system in patients with severe COVID-19., Competing Interests: The authors declared no conflicts of interest.

Although numerous studies have investigated the molecular basis of male infertility, various aspects of this area have remained uncovered. Over the past years, researchers have reported the significant potential of miRNAs in posttranscriptional regulatory roles. By targeting mRNAs, these notable molecules can modulate the processes related to male infertility. On the other side, the outstanding potential of male germline stem cells, SSCs, includes their application in infertility treatment. SSCs retain normal spermatogenesis and fertility by adjusting both SSC self-renewal and differentiation. Therefore, for the characterization and manipulation of SSCs, effective and efficient in vitro culture methods are essential in supporting their maintenance and development. In this regard, the present investigation was undertaken to evaluate the impact of one of the recently conspicuous miRNAs, miR-106b, in SSCs enrichment. As a result, we first found that the SSCs induced with miR-106b-5p highly express TGF-β1, which is known as a regulator of epigenetic modifiers and downstream genes. We next sought to show that self-renewal markers, including c-Myc, Oct-4, and Sox2, are increased in the induced SSC group. The intended miRNA also induced the inhibitor of differentiation 4 (ID4) and aided to remain unmethylated in SSCs. Additionally, for the tumorigenicity possibility of the manipulation, we indicated that PTEN, a tumor-suppressor gene, expressed remarkably in the induced SSCs. In conclusion, our findings showed that miR-106b-5p enhances the proliferative potential of SSCs, making it a substantial factor for therapeutic strategies of male infertility., (© 2022.

The key role of fibrosis and hypertrophy processes in developing diabetes-induced heart injury has been demonstrated. Considering the known hypoglycemic effects of olive leaf extract (OLE), we decided to investigate its potential effect and associated mechanisms on cardiac fibrosis and myocardial hypertrophy in streptozotocin (STZ)-induced diabetic rats. Eight groups were included in this study: control, diabetic, diabetic-OLEs (100, 200 and 400 mg/kg), diabetic-metformin (300 mg/kg), diabetic-valsartan (30 mg/kg), and diabetic-metformin/valsartan (300/30 mg/kg). After a treatment period of 6 weeks, echocardiography was used to assess cardiac function. Heart-to-body weight ratio (HW/BW) and fasting blood sugar (FBS) were measured. Myocardial histology was examined by Masson's trichrome staining. Gene expressions of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), β-myosin heavy chain (β-MHC), TGF-β1, TGF-β3, angiotensin II type 1 receptor (AT1), alpha-smooth muscle actin (α-SMA), and collagen were evaluated by the quantitative real-time PCR in heart tissue. A reduction in the FBS level and HW/BW ratio in the extract groups was obvious. The improvement of left ventricular dysfunction, cardiac myocytes hypertrophy, and myocardial interstitial fibrosis was also observed in treated groups. A lowering trend in the expression of all hypertrophic and fibrotic indicator genes was evident in the myocardium of OLE treated rats. Our data indicated that OLE could attenuate fibrosis and reduce myocardial hypertrophy markers, thus improving the cardiac function and structure in the STZ-induced diabetic rats. PRACTICAL APPLICATIONS: This study demonstrates that olive leaf extract in addition to lowering blood glucose levels and the heart-to-body weight ratio (HW/BW) may also improve cardiac function and reduce cardiac hypertrophy and fibrosis in cardiac tissue, which leads to inhibition of diabetic heart damage. Thus it is possible that including olive leaf extracts in the diets of individuals with diabetes may assist in lowering cardiovascular disease risk factors., (© 2022 Wiley Periodicals LLC.)

This research seeks to determine mechanisms in developing collaborative networking among agricultural production cooperatives in Iran. The research design was survey method and a network consisting of agricultural cooperatives has been defined as the core of the network. The statistical population of the study included managers of cooperatives which were administrated by the "Ministry of Cooperatives, Labour and Social Welfare" and the "Rural Cooperative Organization" of the Alborz Province (N = 540). From this target population, 176 managers of cooperatives were selected by multi-stage cluster sampling. A questionnaire was developed to determine the technical, economical, educational, legal, social, and policy making mechanisms that presented the collaborative networking model. The validity of the questionnaire was confirmed by experts in the field of Agricultural cooperative. To calculate the reliability coefficient of the questionnaire, Cronbach's alpha coefficient, which is used for multi-scale questions, was used. The mean of Cronbach's alpha coefficients in this study was 0.803. The results showed that policy making with a coefficient of 0.539, economic with a coefficient of 0.499, legal with a coefficient of 0.208, and educational mechanisms with a coefficient of 0.130 had the most impact, while technical and social mechanisms had no role in developing the collaborative networking., Competing Interests: The authors declare no conflict of interest., (© 2022 The Author(s).)

Introduction: Burn patients undergo daily painful wound care procedures, including washing, debridement, and dressing. This systematic review and meta-analysis aimed to examine the effect of virtual reality (VR)-based interventions on pain during wound care in burn patients., Methods: A comprehensive systematic search was conducted on international electronic databases such as Scopus, PubMed, and Web of Science with keywords extracted from Medical Subject Headings such as "Virtual reality", "Virtual reality therapy", "Virtual reality exposure therapy", "Virtual reality immersion therapy", "Exergaming", "Active-video gaming", "Burns", "Wound healings", "Pain", and "Pain management" from the earliest to May 6, 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to assess the quality of randomized control trials and quasi-experimental studies., Results: 1,293 patients with burns were included in 30 studies, and their mean age was 22.89 (SD=7.63) years. 70.72% of the participants were male, and 67.05% were in the intervention group. This meta-analysis showed that VR significantly decreased pain severity in the intervention group compared to the control group (standard mean difference (SMD): -0.70, 95%CI: -0.97 to -0.43, Z=5.05, P<0.001, I 2 :82.0%). Immersive VR intervention showed statistically significant effects in reducing pain intensity among the intervention group, compared to the control group (SMD: -0.73, 95%CI: -0.97 to -0.49, Z=5.88, P<0.001, I 2 :69.3%); however, this finding was not the same for non-immersive VR (SMD: -0.62, 95%CI: -1.43 to 0.19, Z=1.51, P=0.132, I 2 :91.2%)., Conclusion: It is suggested that health policymakers and managers equip burn wards with immersive VR devices to provide the basis for this intervention when caring for patients with burn wounds., Competing Interests: The authors declare no conflict of interest.

Objective: According to the mounting data, microRNAs (miRNAs) may play a key role in reprogramming. miR-106b, is considered as an enhancer in reprogramming efficiency. Based on induced pluripotent stem cells (iPSCs), cell treatments have a huge amount of potential. One of the main concerns about using iPSCs in therapeutic settings is the possibility of tumor formation. It is hypothesized that a procedure that can reprogram cells with less genetic manipulation reduces the possibility of tumorigenicity., Materials and Methods: In this experimental study, miR-106b-5p transduced by pLV-miRNA vector into mice isolated spermatogonial stem cells (SSCs) to achieve iPS-like cells. Then the transduced cells were cultured in specific conditions to study the formation of three germ layers. The tumorigenicity of these iPS-like cells was investigated by transplantation into male BALB/C mice., Results: We show that SSCs can be successfully reprogrammed into induced iPS-like cells by pLV-miRNA vector to transduce the hsa-mir-106b-5p into SSCs and generating osteogenic, neural and hepatoblast lineage cells in vitro as a result of pluripotency. Although these iPS-like cells are pluripotent, they cannot form palpable tumors in vivo., Conclusion: These results demonstrate that infection of hsa-mir-106b-5p into SSCs can reprogram them into iPSCs, and advanced germ cell lineages without tumorigenicity. Also, a novel approach for studying the generation of iPSCs, and the application of iPS or iPS-like cells in regenerative medicine is presented.

Background & Objective: The Paris System for Reporting Urinary Cytology (TPS) is a new method for evaluating urinary cytology designed to reduce unreproducible reports. The aim of this study was to reclassify and compare urinary cytology reports with TPS criteria to determine the frequency of unreproducible reports compared to the previous system., Methods: In this study, the laboratory electronic registration system analyzed patients' urine samples taken by voided or washing and brushing methods. The cytological evaluation was performed considering the previous system and TPS by a pathologist. The results of the two systems were compared, and the sensitivity and specificity of TPS were calculated., Results: Urine samples were taken from 876 patients. The mean age of patients was 63.36 ± 12.62. Comparing the routine classification system and TPS, it was observed that the number of atypical reports in the TPS system decreased by 12%, and all of these cases were downgraded to the negative group in the new classification. The sensitivity and specificity of TPS were 29.4% and 95.1%, respectively, if suspected malignancy and positive reports for malignancy were considered. Finally, if positive reports for malignancy were selected, sensitivity and specificity changed to 11.8% and 100%, respectively., Conclusion: Although the TPS system has low sensitivity for the diagnosis of urothelial malignancies, due to its high specificity, it is possible to consider and use this classification for screening patients., Competing Interests: The authors declared no conflict of interest.

Circular RNAs (circRNAs) are non-coding RNAs with closed ends which makes them resistant to degrading enzyme RNAse R. These RNA molecules show cell, tissue or organ specific expression. Regulatory functions have been reported for a number of circRNAs. Particularly, they have been found to affect cell cycle and control cell proliferation. CircRNAs are involved in physiological processes like natural organ development. Their dysregulation in high-throughput technologies have been shown in a growing number of diseases especially many types of cancers such as renal cell carcinoma (RCC). Differentially expressed circRNAs in RCC tissues compared to normal tissues may affect carcinogenesis process. Overexpressed circRNAs promote tumorigenic functions of RCC cell lines while down-regulated transcripts repress them. Both dysregulated circRNAs are correlated with clinicopathological features, prognosis and survival in RCC patients which along with their acceptable diagnostic values suggest them as potential biomarkers in diagnosis or prediction of prognosis of RCC patients. In this review, we have assessed tumorigenic or tumor-suppressing effects of circRNAs and also their diagnostic and prognostic potentials in RCC., (Copyright © 2021 Elsevier GmbH.

Background: COVID-19 infection has recently become a pandemic disease around the world, and its risk factors have not fully evaluated. This study aimed to compare the serum vitamin D (Vit D) and zinc levels in patients infected with novel coronavirus and healthy volunteers (HVs)., Methods: This was a single-center, cross-sectional study conducted on 56 patients (32 severe cases and 24 nonsevere) admitted to the COVID-19 ward and 46 HVs living in Esfarayen City, North Khorasan Province of Iran. Serum levels of Vit D and zinc in admitted patients to the COVID-19 ward and HVs were measured., Results: The average levels of serum Vit D in severe cases, nonsevere cases, and HVs were 31.03 ± 15.49, 37.25 ± 18.49, and 39.33 ± 14.83, respectively ( P = 0.05). Moreover, the average concentrations of serum zinc in severe cases, nonsevere cases, and HVs were 31.03 ± 15.49, 37.25 ± 18.49, and 39.33 ± 14.83, respectively ( P = 0.01). Mortality rate, reinfection (for 5 months), and length of hospital stay in severe cases were higher than in nonsevere cases ( P > 0.05)., Conclusions: Results showed that severe cases had lower levels of Vit D than did other groups and were marginally significant. Also, severe cases had a significantly low level of zinc when compared with nonsevere cases and HVs. Levels of Vit D and zinc can affect the incidence of COVID-19 infection., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background & Objective: Urothelial carcinoma is the seventh most common cancer in the world. The histological classification of papillary carcinoma is one of the most important determinants for its prognosis. Sometimes there is an overlap in the extent of the tumor, and the accurate microscopic diagnosis of the tumor is not always easy. The aim of this study was to evaluate P53 and CK20 immunohistochemical markers in comparison with morphologic findings in low- and high-grade urothelial carcinomas., Methods: For this descriptive study, urinary bladder samples were collected from 50 cancer patients who had undergone biopsy and surgery in Shohaday-e Tajrish Hospital of Tehran, Iran, during the years 2015-2016. P53 and CK20 were studied, and the demographic and histopathological characteristics of the tumor were also analysed., Results: The mean age of patients enrolled in this study (48 males and 2 females) was 65.8±11.9. Twenty-five cases presented with low-grade and 25 cases presented with high-grade papillary urothelial carcinomas. Sensitivity, specificity, and positive and negative predictive values for P53 were 48%, 80%, 70.5%, and 60.6%, respectively, while the same values for CK20 were 44%, 92%, 84.6%, and 62.2%, respectively. Immunohistochemical results were also positively correlated with the extent of the tumor., Conclusion: Based on the results, P53 and CK20 may serve as specific markers for diagnosis of low- and high-grade papillary urothelial carcinoma but not sensitive. P53 and ck20 staining have also a high specificity as 80% and 92% and low sensitivity compared to the low and high morphology of papillary carcinoma, thus their positive and their staining intensity are valuable for diagnosis, but their negative results are not determinant., Competing Interests: The authors declare no conflict of interest.
