Shohre Behrouz, Alireza Ebrahimi , Ehsanmoosa Farkhani,
Volume 82, Issue 2 (5-2024)
Abstract
Background: Breast cancer is one of the most important cancers in women. Considering the importance of design for improving physical and mental health, quality of life of vulnerable women, the present study aims to design of humor and laughter programs in women with breast cancer and its effects in promoting their health.
Methods: In this systematic review, in order to access relevant articles used from Persian and English databases SID, Magiran, Cochrane Library, MEDLINE/PubMed, Scopus and Science direct, and the key words "Humor therapy", "Laughter therapy", "Breast Cancer", "Wit and Humor as Topic" and "Breast Neoplasms" using logical operators (AND, OR, NOT) were used. All articles were evaluated between January 2008 and January 2023. To assess the quality of the articles, the "Jadad" scale was used.
Results: Among the 975 articles in the initial search, 525 articles are due to the repetition of the title and 442 articles due to other reasons such as not assigning humor therapy in breast cancer, not implementing the joke and laughter intervention program, the language of the article not being related to English or Farsi, and not Conducting clinical trials were excluded, and finally eight articles that scored higher than 3 were included in the systematic review. The results of the studies showed that laughter therapy had an effective role in improving the quality of life, improving various aspects of mental health, reducing negative emotions such as anxiety, stress, depression, pain intensity, fatigue and strengthening positive emotions such as self-esteem, mood. while There has been a non-significant decrease in the dermatitis caused by radiotherapy and the activity of immune cells and the serum level of cortisol.
Conclusion: Considering the positive effect of laughter therapy in reducing the negative emotions of patients, it is recommended that nursing managers and psychologists use this easy, fun, uncomplicated and accessible intervention to improve the physical, mental and emotional health of women with breast cancer.

Seyed Hasan Emami Razavi , Mohammadreza Salehi, Hooshang Saberi , Mohammad Zarei, Babak Mirzashahi, Pegah Afarinesh, Sepideh Khodaparast,
Volume 82, Issue 3 (6-2024)
Abstract
Primary pyogenic spinal infection, also known as spondylodiscitis or vertebral osteomyelitis, is a serious and potentially debilitating condition involving a bacterial or fungal infection of the intervertebral disc space and adjacent vertebral bodies. While relatively uncommon, with an estimated incidence of 2.4 per 100,000 population per year, it is a medical emergency that requires prompt diagnosis and treatment to prevent permanent spinal damage and neurological complications. The most common causative organisms are Staphylococcus aureus, which accounts for up to 50% of cases, followed by Gram-negative bacteria such as Escherichia coli, and mycobacterial infections like Mycobacterium tuberculosis. Risk factors for developing primary pyogenic spinal infection include intravenous drug use, a weakened immune system, recent spinal surgery or instrumentation, and contiguous spread from an infection elsewhere in the body, such as a urinary tract infection or endocarditis. Patients typically present with severe, localized back pain, fever, and general malaise, which can easily be mistaken for more common spinal conditions. Prompt diagnosis is critical and involves a thorough medical history, physical examination, laboratory testing, and advanced imaging studies such as magnetic resonance imaging (MRI). Blood cultures and, in some cases, image-guided biopsy may be necessary to identify the causative organism and guide appropriate antimicrobial therapy. The mainstay of treatment is the prompt initiation of targeted antibiotic or antifungal therapy, often requiring intravenous administration for several weeks. Surgical intervention may be necessary in some cases, such as to drain an abscess or provide spinal stabilization. A multidisciplinary approach involving infectious disease specialists, spine surgeons, and rehabilitation providers is essential for optimal management and outcomes. Despite advances in diagnosis and treatment, primary pyogenic spinal infection remains a challenging condition. Delays in diagnosis and treatment can lead to devastating complications, including permanent spinal deformity, paralysis, and even death. With timely and appropriate management, however, most patients are able to achieve a good clinical outcome, though some may experience residual pain or neurological deficits.

Assessment of studies on the use of platelet-rich plasma in shoulder tendinopathy: a review article
Nima Bagheri, Mahdieh Ghiasi, Khalil Pestehei,
Volume 82, Issue 4 (7-2024)
Abstract
Tendon ruptures may occur as a result of acute injuries or degenerative changes in the tendons caused by aging, excessive and long-term use of the shoulders, and sudden wear and tear. This tear may be partial or completely separate the tendon from its attachment to the bone. Rotator cuff tendinopathy of the shoulder is one of the common causes in patients that affect the daily performance and quality of life. Tendinopathy problems are one of the most common problems of people who refer to medical centers, and in some people, improvement is very important because of their job position. Platelet-rich plasma has received attention due to having growth factors involved in tissue repair in tendinopathy patients. This review study examined the clinical effect of platelet-rich plasma injection in rotator cuff tendinopathy, as well as other studies comparing it with corticosteroids. A literature search was conducted in various scientific databases to obtain articles up to 2022 examining the clinical effects of PRP injection on tendinopathy. Platelet-rich plasma (PRP) is one of the products derived from blood that contains a greater number of physiological platelets. PRP contains a large amount of growth factors such as TGF-β, platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), which play an important role in cell proliferation, cell differentiation, chemotaxis and angiogenesis. These growth factors are significantly upregulated following tendon injury and are active at different stages of the healing process. Platelet-rich plasma is an autologous source of growth factors and has been shown to be beneficial in the treatment of tendinopathy and osteoarthritis. PRP injection can be recommended as a suitable and desirable method in tendinopathy and rotator cuff tear patients, especially in adults, and can be substituted for corticosteroids. PRP is a minimally invasive treatment method that is used to treat muscle diseases and tendon injuries. In this method, blood is taken from the person, and after that, the components of the blood are separated during a process, and the platelet-enriched plasma is re-injected into the muscles and tendons of the shoulder.

Impact of viral oncoproteins on human genome methylation: a review article
Farzane Hayati, Esma’il Akade, Negar Dinarvand, Gholam Abbas Kaydani , Shahram Jalilian,
Volume 82, Issue 6 (9-2024)
Abstract
Epstein-Barr virus (EBV), human herpesvirus 8 (HHV-8), hepatitis B virus (HBV), human papilloma virus (HPV), Merkel cell polyomavirus (MCPyV), human lymphotropic virus type 1 (HTLV-1) and Hepatitis C virus (HCV) are among the most important viruses that cause cancer in humans. These viruses are collectively known as oncoviruses due to their potential to induce malignant transformations in host cells. Oncoviruses exert their cancer-causing effects by utilizing various viral oncoproteins and non-coding RNAs, which can drive host cells toward malignancy through multiple pathways. One critical strategy these viruses employ involves altering the host cell's regulatory mechanisms, particularly by influencing DNA methylation processes.
DNA methylation is a crucial modification that occurs on the promoter regions of genes, effectively reducing their expression levels. Under normal cellular conditions, a delicate balance of methylation and demethylation is maintained by a specific set of enzymes. Key players in this process include DNA methyltransferases (DNMTs) and TET methylcytosine dioxygenases (TETs), which are pivotal in regulating gene expression through methylation. These enzymes are prime targets for oncoviruses because, by altering their activity, viruses can hijack the host cell's regulatory machinery. Viral oncoproteins, though diverse in structure and function, often converge on disrupting the expression of these enzymes. By doing so, they induce widespread changes in DNA methylation patterns, effectively reprogramming the gene expression landscape of the host cell. This reprogramming is not random; rather, it is a calculated mechanism through which oncoviruses can manipulate the cell cycle, promoting uncontrolled cellular proliferation and progression towards cancer. By suppressing or activating specific genes, these viruses can push cells past normal checkpoints, eventually leading to tumor formation. Despite the critical role of DNA methylation in cancer development, the precise mechanisms by which oncoviruses modulate these methylation processes are not fully understood. Researchers have made significant progress in exploring the connection between viral infections and cancer, but many of the detailed pathways through which oncoviruses control methylation remain to be elucidated. As a result, this area remains a fertile ground for further research, offering potential avenues for therapeutic intervention in virus-induced cancers.

An overview of the types of neural networks used in the examination of panoramic radiographic images: a narrative review
Mahdieh Soltani , Seyyede Zohreh Seyyedsalehi, Reyhane Mahdavi,
Volume 82, Issue 9 (12-2024)
Abstract
With the rapid expansion of artificial intelligence across clinical disciplines, a variety of artificial neural networks (ANNs) have become indispensable tools for endowing computer systems with advanced analytical power. Dentistry, as an information‑rich branch of medicine, routinely generates and must interpret large, complex datasets from imaging and diagnostic records. Consequently, researchers have increasingly directed their attention toward intelligent, automated techniques for analyzing dental data. This study therefore surveys and synthesizes the methods that have been applied to the intelligent and automated analysis of such data, highlighting the prevailing trends in current literature.The majority of the examined investigations relied on panoramic radiographic images of the teeth orthopantomograms (OPG) as their primary source material. Three overarching technical objectives repeatedly emerged: first, tooth diagnosis, meaning the reliable separation and identification of each individual tooth from its neighbors; second, sample segmentation, that is, the piece‑by‑piece analysis of visual information within the image; and third, semantic segmentation, namely, the contextual interpretation of information extracted from the radiograph. Depending upon which of these objectives was pursued, researchers selected different neural‑network architectures and configurations. Across the reviewed corpus, input images were typically subjected to preprocessing steps such as normalization, noise reduction, and contrast enhancement before being supplied to a neural network for training, thereby preparing the data for subsequent machine interpretation. In several instances, the raw output produced by the neural network underwent additional post‑processing, a stage designed to refine the preliminary results and enhance overall accuracy. The comparative analysis presented here concentrates on how effectively the various neural‑network models fulfilled the three technical objectives described above. The surveyed articles reveal two dominant analytical approaches. In the intelligent problem‑solving paradigm, convolutional neural networks (CNNs) overwhelmingly predominate. Conversely, in the automated paradigm, investigators favor classical, non‑learning algorithmic techniques. Work employing ANNs consistently emphasizes image comprehension, segmentation, feature extraction, feature classification, network modeling, and careful variable tuning to promote effective learning that aligns with each study’s stated objectives.

Relation between Helicobacter pylori Infection and gastrointestinal cancer by IL-21, and IL-23: a review article
Fatemeh Kiaee, Kiyana Bahani, Heshmat Shahi,
Volume 82, Issue 11 (2-2025)
Abstract
Background: Helicobacter pylori (H. pylori) infection is the most common infection worldwide and results in chronic gastritis, and rarely gastric carcinoma. Chronic inflammation, which is a major engine of disease development. Is dominantly controlled by adaptive and humoral immunity. This study reveals the intricate IL-21 and IL-23 relationship in H.pylori associated diseases as well as inflammatory GI disorders, as the crtically govern the differentiation and activity of T helper 17 (TH17) cells in the gastric mucosa. Understanding these cytokines pathways is essential for comprehending the immune pathogenesis of H. pylori infection and its outcome.
Methods: A literature search was conducted in the PubMed database using the MESH keywords "Helicobacter pylori" "Interleukin 21," "Interleukin 23," and "gastric cancer" to identify relevant English-language studies. Articles that were reviews, case reports, or letters to the editor were excluded.
Results: IL-23 significantly exacerbates both intestinal and gastric inflammatory responses by stimulating T cells particularly Th17 cell subsets, through the mediation of STAT3 signaling pathways and reducing IL-10 production, while T cells lacking the IL-23 receptor promote Treg expansion and intestinal homeostasis. IL-21 is implicated in chronic inflammation of the gastric and intestinal mucosa, with elevated levels observed in ulcerative colitis patients, contributing to the recruitment of inflammatory cells, increased inflammation, and angiogenesis. This particular cytokine plays an essential role in the recruitment of inflammatory cells, the increase of tissue inflammation, and the promotion of pathological angiogenesis. Moreover, IL-21 exerts influence over B cell differentiation and the production of antibodies, establishing a connection to humoral immune responses within chronic inflammations.
Conclusion: CD4+ T helper 17 (Th17) cells exhibit both antimicrobial and pathogenic immune functions in the gastrointestinal environment. These processes are interconnected, as cytokines such as IL-21 and IL-23 are essential for Th17 cell maintenance and support humoral immune responses. A comprehensive understanding of the dynamic immunological interactions in H. pylori-related and inflammatory gastrointestinal diseases may facilitate the development of novel immunology-based therapeutic interventions.
 
Comparison of all-cause mortality in AF patients with PCI (percutaneous coronary intervention) history treated with low dose (110 mg) versus a high dose (150 mg) of dabigatran: a systematic review and meta-analysis

Abstract
Background: Coronary artery disease (CAD) is among the most common life-threatening cardiovascular diseases, in which blood supply to the heart muscles is reduced or completely blocked. Coronary artery disease has various treatment options, one of which is PCI (Percutaneous Coronary Intervention) or stent placement via angioplasty. Dabigatran etexilate is the only orally available direct thrombin inhibitor, which is actually a prodrug that is rapidly converted to its active form and absorbed through the gastrointestinal tract. The purpose of this study is to compare mortality in patients with Atrial Fibrillation (AF) with a history of Percutaneous coronary intervention (PCI) treated with a low dose (110 mg). In contrast, it was treated with a high dose (150 mg).
Methods: The present study was a systematic review and meta-analysis on 4 online databases PubMed, Scopus, Web of Science and EMBASE to find articles that the rate of long-term complications related to bleeding or Thrombotic events were performed in AF patients who underwent PCI and were treated with dabigatran. STATA software was used for data analysis.
Results: Nine RCTs or prospective studies with 5694 participants were included. The studies showed that when comparing dabigatran (110 and 150 mg) with warfarin (with/without dual antiplatelet), dabigatran 110 mg was associated with a significant reduction in major bleeding (OR=0.46, 95% CI: 0.24-0.86, P=0.01), while the 150 mg dose was not statistically different (OR=0.12, 95% CI: 0.01-1.32, P=0.08). Also, comparing dabigatran 150 with 110 mg showed a higher risk of bleeding at the higher dose (OR=0.77, 95% CI: 0.64-0.92, P<0.001). On the other hand, dabigatran 110 mg was associated with a significant increase in mortality (OR=1.33, P=0.01) and myocardial infarction (OR=1.61, P=0.01) compared with combination therapy of warfarin and antiplatelet, but the 150 mg dose did not show a statistical difference. Heterogeneity was high in some analyses (I2 up to 99.49%), but funnel plots and Egger's test rejected publication bias.
Conclusion: There seems to be strong evidence that bleeding complications in dabigatran are less than old antiplatelet and anticoagulation drugs, but in terms of efficacy in reducing mortality, although we did not obtain strong evidence for analysis, older drugs are more effective in preventing death from any cause.

Volume 82, Issue 12 (3-2025)
Abstract
Background: Infertility is defined as the failure to achieve pregnancy after one year or more of regular unprotected sexual intercourse. Assisted reproductive technologies (ART) represent a key therapeutic approach for infertile couples. Bisphenol-A (BPA), a compound found in plastic polymer products, has been associated with increased infertility risk. This systematic review addresses whether BPA affects ART outcomes.
Methods: A comprehensive and systematic literature search was conducted across PubMed, Google Scholar, Web of Science, and Scopus up to December 2024 without any language or time restrictions. The search strategy combined relevant keywords and medical subject headings such as “bisphenol A,” “infertility,” “assisted reproductive technology,” “in vitro fertilization,” and “embryo implantation.” All human studies assessing the relationship between BPA exposure and ART outcomes were considered. After removing duplicates and screening titles and abstracts, 23 studies that met the inclusion criteria were reviewed in detail. The selected studies included cross-sectional and prospective cohort designs, and data on sample size, BPA measurement methods, and reproductive endpoints were extracted for qualitative synthesis.
Results: The reviewed studies consistently indicate that exposure to BPA is associated with adverse reproductive outcomes, particularly in women undergoing IVF treatment. Evidence suggests that higher BPA levels correlate with fewer retrieved oocytes, reduced oocyte maturation rates, and impaired ovarian response to hormonal stimulation. Several studies also observed reduced estradiol concentrations and lower fertilization and cleavage rates, leading to decreased implantation success and clinical pregnancy rates. In addition, diminished ovarian reserve markers, such as anti-Müllerian hormone and antral follicle count, have been negatively influenced by BPA exposure. Male factors were also affected, with reports of decreased sperm motility, abnormal morphology, and increased DNA fragmentation, which could compromise embryo quality and early development. Variability in study methodologies, small sample sizes, and differences in BPA detection techniques, however, make direct comparison challenging.
Conclusion: Current evidence supports an inverse association between BPA exposure and fertility outcomes, but further prospective studies with larger sample sizes and more precise measurement methods are needed.

An overview on hyperthyroidism: pathogenesis, diagnosis ,management, complications and prognosis: a review article
Sahar Karimpour Reyhan , Mahsa Abbaszadeh, Alireza Esteghamati ,
Volume 83, Issue 1 (4-2025)
Abstract
Hyperthyroidism is one of the most important endocrine disorders, characterized by increased activity of the thyroid gland and excessive production of thyroid hormones. These hormones play a key role in regulating the body’s metabolism; therefore, their excess leads to a wide range of clinical manifestations. The most common symptoms include anxiety, restlessness, weight loss despite normal or even increased appetite, palpitations, excessive sweating, fine tremors of the hands, sleep disturbances, and heat intolerance. Some patients may also experience mood changes such as irritability and nervousness. On physical examination, rapid tendon reflexes, tachycardia, moist and thin skin, and in many cases the presence of goiter (thyroid enlargement) may be observed. The condition is more common in women than men and is most frequently seen between the ages of 20 and 50 years. Once hyperthyroidism is confirmed, the underlying cause of thyrotoxicosis must be determined. The most common cause is Graves’ disease, an autoimmune disorder that leads to diffuse thyroid enlargement and overproduction of hormones. Toxic multinodular goiter and solitary toxic adenoma are other important causes. For definitive diagnosis, blood tests measuring TSH, T3, and T4 are essential. In hyperthyroidism, TSH is typically suppressed while T3 and T4 are elevated. In addition to laboratory testing, thyroid ultrasound can help evaluate the structure of the gland, and a thyroid radioactive iodine uptake scan can further differentiate between different causes and determine disease activity. Several treatment options are available for managing hyperthyroidism. Antithyroid drugs such as methimazole or propylthiouracil inhibit the synthesis of thyroid hormones. Beta-blockers are often prescribed to control cardiovascular symptoms and reduce palpitations. Radioactive iodine therapy is a common and effective method that destroys the overactive thyroid tissue. In rare cases, or when other treatments fail, thyroidectomy (surgical removal of part or all of the thyroid gland) may be required. Overall, hyperthyroidism is a manageable condition, but it requires accurate diagnosis, careful selection of therapy, and close follow-up with a specialist. Patient cooperation and adherence to treatment play a crucial role in controlling symptoms and preventing long-term complications. This review will focus on describing the symptoms, causes, diagnostic methods, and treatment options.

Abstract
Artificial intelligence (AI) has emerged as a transformative force in modern medicine, with ophthalmology standing at the forefront of its clinical integration. Among ophthalmic disorders, glaucoma—a leading cause of irreversible blindness worldwide—presents unique opportunities and challenges for AI-based solutions due to its chronic, progressive nature and reliance on multimodal data, including structural and functional assessments. This review article offers a comprehensive synthesis of the current and emerging roles of AI in the detection, monitoring, and management of glaucoma. AI algorithms, particularly deep learning and machine learning models, have demonstrated exceptional capabilities in interpreting fundus photographs, optical coherence tomography (OCT) images, and visual field data to identify glaucomatous damage. These systems often approach or even exceed the diagnostic performance of human experts. Moreover, AI has shown significant promise in facilitating large-scale population-based screening, improving early detection rates, and addressing disparities in access to subspecialty care, particularly in low-resource and remote settings. In the monitoring of disease progression, AI tools are being developed to detect subtle structural or functional changes over time, predict future visual outcomes, and support more precise and individualized treatment decisions. Despite these advancements, the widespread clinical adoption of AI in glaucoma care faces several critical barriers. Key limitations include poor generalizability of models across diverse populations, imaging devices, and clinical settings; scarcity of well-annotated, high-quality, and demographically representative datasets; and a lack of transparency and interpretability in algorithmic decision-making—commonly referred to as the “black box” problem. Ethical concerns, regulatory uncertainty, integration challenges within existing healthcare infrastructures, and medico-legal accountability also require thoughtful resolution before AI can be reliably deployed in clinical practice. This review critically evaluates the strengths, limitations, and real-world potential of AI technologies in glaucoma. It provides clinicians, researchers, and healthcare policymakers with a balanced and up-to-date perspective, highlighting promising avenues for future research, including explainable AI, federated learning, multi-modal data integration, and longitudinal validation studies. By fostering a deeper understanding of both the opportunities and challenges associated with AI, this article aims to guide the responsible, equitable, and evidence-based integration of AI into comprehensive glaucoma care.

Non-pharmacological methods of anxiety control in patients undergoing orthopedic surgery: a review article
Shahram Shafa, Mehrdad Sayadinia, Bibi Mona Razavi, Tayyebeh Zarei , Maryam Ziyaei , Mansour Deylami,
Volume 83, Issue 2 (5-2025)
Abstract
Background: Controlling patients' anxiety before surgery reduces the possibility of postoperative problems and increases the possibility of patient participation and cooperation in the postoperative care and treatment plan.
Methods: This study uses a review approach to investigate non-pharmacological methods of anxiety management in patients undergoing orthopedic surgery. The systematic search involves several key steps. Literature search: A thorough search was conducted in PubMed, Sciences Direct, Scopus, Magiran, Sid, and Google Scholar databases. The search was refined using keywords such as “aromatherapy,” “music therapy,” “massage,” “educational intervention,” “educational film,” and “sound of the Quran” and their English equivalents to identify relevant studies published in the past ten years. Inclusion criteria included studies on orthopedic surgery, Persian and English articles, and original articles. Exclusion criteria included studies outside the specified time frame or studies that deviated from the defined focus. In this review, we conclude by summarizing key aspects of the review process, emphasizing the rigorous approach applied in study selection, data extraction, and synthesis.
Results: The results of the present study showed that the non-pharmacological methods used to control or reduce anxiety in orthopedic surgery include methods; Music therapy, the sound of the Quran, relaxation techniques, back massage, educational intervention, educational video, awareness and training before surgery and aromatherapy (chamomile, lemon, rose, valerian, cardamom, cinnamon, calendula, lavender, lemon sour).
Conclusion: The results of numerous and reputable research findings clearly show that the use of non-pharmacological methods plays an effective role in reducing the level of anxiety of patients before, during and after orthopedic surgery. These methods, which are generally low-cost, low-complication, and applicable in various clinical settings, include techniques such as preoperative education, music therapy, breathing and relaxation techniques, mindfulness-based interventions, psychological support, and the creation of a calm and reassuring environment. Since anxiety is a known factor in weakening the immune system, increasing postoperative pain, prolonging the recovery period, and reducing overall patient satisfaction, its management is of great importance. Therefore, by integrating and utilizing such non-invasive methods into nursing care protocols and holistic patient care programs, the detrimental and undesirable effects of anxiety after orthopedic surgery can be significantly reduced and faster recovery, a better patient experience, and more favorable clinical outcomes can be achieved.

Volume 83, Issue 2 (5-2025)
Abstract
Background: Today, cesarean section is one of the most common surgeries performed in different countries. Shivering after surgery is one of the common complications of spinal anesthesia in cesarean surgery. Many drugs have been investigated to prevent or reduce shivering, but the ideal drug has not yet been finally approved. The purpose of this study is to investigate the effect of dexmedetomidine in preventing shivering after cesarean section surgery under spinal anesthesia in the form of a systematic review.
Methods: In this systematic review, the Persian keywords "dexmedetomidine", "spinal anesthesia", "caesarean" and dexmedetomidine" and the English keywords dexmedetomidine", "Caesarean section", "Spinal Anesthesia" "Dexmedetomidine and "C-Section" in databases PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Clinical Trials.gov and Scopus, SID, Magiran, Medlib and Google Scholar search engine, without time limit Done. Data extraction was performed independently by two authors. Study name, year of study, country, study groups, and incidence of shivering were extracted from the studies. Our primary outcome was the severity of shivering in patients. All disagreements in data extraction were resolved through discussion between the reviewers or, if not possible, by a third reviewer. Data were entered into an Excel file.
Results: In this systematic review, 19 studies were examined. The total number of patients included in the study was 2001 patients. The study range was from 2016 to 2022. The age group of most patients was between 18-45. The drugs studied in combination with dexmedetomidine in the studies included: pethidine, dexamethasone, nalbuphine, ondansetron, and morphine. The most studied drugs were pethidine and dexamethasone in three studies. In 13 studies, dexmedetomidine was more effective in controlling shivering than the other groups studied. Also, in five studies, dexmedetomidine, along with three drugs: pethidine, dexamethasone, and ondansetron, had similar effects in controlling shivering in patients. In one study, dexmedetomidine produced less anti-tremor effects than nalbuphine.
Conclusion: In the review of the studies, the results indicated that dexmedomedin is effective in preventing post-operative shivering in patients undergoing caesarean section. Therefore, it seems that the use of dexmedetomidine to prevent shivering after surgery is useful in these patients.

Volume 83, Issue 3 (6-2025)
Abstract
Background: Trichomonas vaginalis is one of the main causes of vaginitis and cervical inflammation worldwide. Almost half of sexually transmitted and curable diseases worldwide can be assessed through the examination of this disease, so the aim of this study is to determine the prevalence of trichomoniasis in Iranian women.
Methods: This study is a review of the SID, PubMed, Science Direct, and Google Scholar databases, conducted up to September 2023. The extracted data were analyzed using CMA software (version 2). A search of articles in Science Direct, SID, PubMed, and Google Scholar databases was conducted in accordance with the PRISMA statement criteria, including systematic search, screening of articles, and selection of appropriate studies. The words used for the search and final review in this systematic review were determined based on MESH Terms in the PubMed database. These keywords that were used and selected in this study were in English and Persian. The final information obtained from the studies was reviewed and analyzed using the Comprehensive Meta-analysis (CMA, Version 2) software, and finally the heterogeneity of the studies was examined with the I2 test.
Results:  Based on the search for studies and their screening, 22 studies were finally included in the meta-analysis. This study included a sample size of 49,990 Iranian women who were included in the study. In the heterogeneity analysis based on the studies obtained, the heterogeneity was 99.7. Due to the heterogeneity of the studies, the random effects method was used for the final analysis. The prevalence of Trichomonas vaginalis in Iranian women was reported to be 9.3 (95% CI: 4.6-18) based on the 22 final studies and meta-analysis. The publication bias analysis indicated the absence of bias in the studies (p: 0.175).
Conclusion:  Based on the prevalence report in the meta-analysis, a relatively high prevalence was reported in Iranian women, and this situation requires more awareness raising through health centers to families, as well as care and screening of women in these centers and also in obstetric centers.
 
Comparison of the benefits and complications of the classic surgical method and the plastic ring method in neonatal circumcision: a systematic review
Reza Saeidi , Mahboobe Gholami,
Volume 83, Issue 4 (7-2025)
Abstract
Background: Neonatal circumcision is one of the most common surgical procedures worldwide, performed for cultural, religious, and health-related reasons. The two primary methods for neonatal circumcision are the classic surgical method (using sutures or clamps such as Gomco or Mogen) and the plastic ring method (e.g., Plastibell). This systematic review and meta-analysis aimed to compare the benefits and complications of these two methods in neonates.
Methods: A systematic search was conducted in PubMed, Scopus, Web of Science, and Google Scholar databases for articles published between 2000 and 2024. Inclusion and exclusion criteria: Included studies included randomized controlled trials (RCTs), cohort studies, and cross-sectional studies that compared the benefits and harms of classical surgery and plastic ring in infants (<28 days). Studies without a comparison group, studies conducted in older children or adults, and articles that did not provide sufficient data were excluded. Keywords included "neonatal circumcision", "plastic ring", "Plastibell", "classical surgery", "Gomco clamp", "Mogen clamp", "benefits", "complications" and their English equivalents.
 Studies comparing the benefits and complications of the classic surgical method and the plastic ring method in neonates were included. Data were meta-analyzed using a random-effects model, and risk ratios (RR) with 95% confidence intervals (CI) were calculated. 
Results: From a total of 12 included studies (involving 5,342 neonates), the plastic ring method was associated with a significant reduction in bleeding (RR: 0.45; 95% CI: 0.32-0.64) and healing time (mean difference: -2.3 days; 95% CI: -3.1 to -1.5) compared to the classic surgical method. However, the risk of skin adhesion was higher with the plastic ring method (RR: 1.32; 95% CI: 1.05-1.66). Serious complications, such as urethral injury, were rare in both methods (less than 0.2%). 
Conclusion: The plastic ring method is a suitable option for neonatal circumcision due to its ease of use, reduced bleeding, and faster healing time. However, careful post-procedural care is essential to minimize the risk of skin adhesion. The choice of method should consider the operator’s expertise and parental preferences. 

Substance abuse in pregnant mothers in Iran: a systematic review and meta-analysis
Reza Saeidi , Mahboobe Gholami ,
Volume 83, Issue 6 (9-2025)
Abstract
Background: Maternal substance abuse during pregnancy is a significant global public health concern, affecting approximately 10% of pregnant women worldwide and leading to serious adverse outcomes for both mother and fetus. Given Iran’s geographical location and its role as a transit route for narcotics, the prevalence of substance abuse, particularly opium and its derivatives, is notably higher than in many other countries. This systematic review and meta-analysis aimed to determine the prevalence of substance abuse and the most commonly used substances (including opium, heroin, crystal methamphetamine, methadone, amphetamines, and cigarettes) among pregnant Iranian women from 2000 to 2024.
Methods: A systematic search was conducted across PubMed, Scopus, Web of Science, SID, and Iranmedex for articles published between January 2000 and January 2024. Studies investigating the prevalence of substance abuse in pregnant Iranian women were included. Case studies, reviews, letters to the editor, and studies without quantitative data were excluded. Two researchers independently extracted data. Extracted information included: author name, year of publication, province/city, sample size, mean age of participants, type of substance used, and incidence or prevalence rate. Data were analyzed using a random-effects model, and heterogeneity was assessed using the I2 index.
Results: Out of 127 identified articles, 22 were included in the meta-analysis. The overall estimated prevalence of substance abuse among pregnant Iranian women was 3.3% (CI 95%: 2.4-4.5), with high heterogeneity (I2=83%). The most prevalent substances were opium (1.7%), cigarettes (1.3%), methadone (0.5%), heroin (0.3%), crystal methamphetamine (0.2%), amphetamines/methamphetamines (0.1%), cannabis (0.4%), and alcohol (0.2%). Polydrug use was reported at 0.7%. A rising trend in substance abuse prevalence was observed, increasing from 2.1% in 2000-2009 to 3.8% in 2015-2024. A temporal trend analysis of the incidence of substance abuse showed that the incidence of substance abuse in Iranian pregnant women increased from 2.1% in 2000-2009 to 3.8% in 2015-2024. Sensitivity and publication bias analyses showed that the exclusion of low-quality studies did not significantly affect the results. The funnel plot indicated a low probability of publication bias.
Conclusion: Substance abuse among pregnant Iranian women remains a serious challenge, necessitating broader preventive and therapeutic interventions.

Volume 83, Issue 6 (9-2025)
Abstract
Helicobacter pylori is one of the most common chronic bacterial infections worldwide, with acquisition often occurring in childhood. While its role in the pathology of gastroduodenal diseases in adults is well-established, its impact on the pediatric population presents a unique set of clinical and pathophysiological challenges. This comprehensive review examines the complex and bidirectional relationship between Helicobacter pylori infection and host iron metabolism in pediatric and infant populations. For this review, the PubMed database was utilized for studies published from April 1979 through December 2024. Studies based on English language were included using the MESH terms "Helicobacter pylori," "iron," and "ferritin." According to the inclusion criteria, studies related to H. pylori infection and iron condition in patients under 18 years old were selected. Articles such as review articles, case reports, letters to the editor, and animal or in vitro studies were excluded. The main aim of this study was to illuminate the critical role of iron as an essential micronutrient and factor for both the host and the pathogen, examining the multifaceted mechanisms involved in H. pylori-induced iron homeostasis disruption in children.
The findings indicate a multifaceted relationship: virulent Helicobacter pylori strains are significantly and inversely associated with true body iron stores, leading to Iron deficiency anemia (IDA). However, chronic inflammatory states can paradoxically elevate ferritin levels, masking underlying iron deficiency. Complex interaction between bacterial infection, host inflammatory responses, and iron deficiency is an important factor influencing both the severity of the damage caused by this bacterial infection and its chronicity in the pediatric population. Identification and comprehensive understanding of these complex mechanisms is of great importance for the effective management of iron deficiency anemia in children with H. pylori infection. Considering, increase in the incidence of H. pylori infection in childhood, it is essential that H. pylori infection be evaluation in children with unknown reasons IDA. Finally, screening methods for H. pylori infection in children is recommended, as this could improve long-term health outcomes.

Volume 83, Issue 7 (10-2025)
Abstract
Inflammatory bowel disease (IBD) is a chronic, relapsing gastrointestinal disorder characterized by persistent inflammation of the intestinal mucosa, disruption of epithelial barrier function, and dysregulation of the immune system. Its pathogenesis involves complex interactions among genetic predisposition, environmental factors, gut microbiota, and host immune responses. Dysregulated cytokine signaling plays a central role, with elevated levels of pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), IL-6, IL-12, and interferon-gamma (IFN-γ), contributing to tissue damage, epithelial barrier dysfunction, and clinical manifestations such as diarrhea, bleeding, and weight loss. Conversely, anti-inflammatory cytokines, including interleukin-10 (IL-10), IL-35, and IL-37, counteract these inflammatory responses, inhibit excessive immune activation, and maintain mucosal homeostasis. Probiotics, particularly Lactobacillus strains, have emerged as promising adjunctive therapies for IBD due to their capacity to restore microbial balance, modulate immune responses, and enhance gut barrier integrity. Among them, Lactobacillus brevis has demonstrated significant immunoregulatory and anti-inflammatory effects. Various strains, including AL0035, SBC8803, Bmb6, HY7401, and KU15152, reduce pro-inflammatory cytokines, upregulate tight junction proteins such as ZO-1, regulate Th1/Th2/Th17 responses, and inhibit NF-κB and MAPK signaling pathways. L. brevis-derived metabolites, notably long-chain polyphosphates, attenuate fibrosis, reduce TGF-β1 and collagen expression, and protect epithelial cells from oxidative stress. Heat-killed L. brevis strains also retain immunomodulatory activity, allowing therapeutic use even when live bacteria cannot effectively colonize the gut. Preclinical studies demonstrate that oral administration of L. brevis improves disease activity indices in experimental colitis models, reduces mucosal immune cell infiltration, restores epithelial integrity, and prevents ulceration, bleeding, and goblet cell depletion. Clinical evidence, although limited, suggests that L. brevis supplementation can enhance gut microbiota diversity, increase beneficial bacterial populations, and modulate serum cytokines, further supporting intestinal homeostasis. Furthermore, L. brevis influences metabolite profiles, such as serotonin and polyamines, which are linked to gut motility, epithelial repair, and immune regulation, highlighting its multifaceted role in gut health. In this review article, for the first time, we discussed the beneficial effects of L. brevis in inflammatory bowel disease, highlighting its clinical effects and therapeutic prospects.

Abstract
Background: The present study is a systematic and comparative review of the studies conducted in the field of hospice centers for patients with acute incurable diseases with a life expectancy of less than six months in the world with the aim of examining the need in Iran and the experiences of other countries, identifying candidates to receive these services, type of services provided, costs and resources in these centers.
Methods: The present study was conducted as a systematic review by searching the databases: Scopus, PubMed, Elsevier, and Google Scholar search engine between 2010 and 2023. To search these databases, keywords such as hospice care centers, centers providing health services for patients with life expectancy less than six months, allocation of resources, allocation were used. After selecting the articles, the following topics were extracted from each article and compared: costs, sources of funding, candidates for receiving services, families' views, quality of near-death care, quality of life, quality of death, services provided, therapeutic interventions performed, place of death, length of stay.
Results: 6 articles referred to the discussion of cost, and in all articles except one case, the use of hospice was associated with reducing the cost of patients. In one study, the source of funding was philanthropic contributions and in another study, the national budget. In all the reviewed articles, the use of hospice was associated with an increase in the quality of care, quality of end of life and quality of death, and a decrease in therapeutic interventions. The care provided by hospice was also introduced in the form of symptom assessment and management, pain relief, psychosocial support and respite care.
Conclusion: Based on the findings of the present study, hospices can play an effective role in reducing treatment costs and, on the other hand, improve the quality of care, life and death in eligible people. In addition, hospices improved the end-of-life quality from the perspective of the deceased's family by reducing invasive interventions and providing physical and spiritual care.

Volume 83, Issue 8 (11-2025)
Abstract
Background: With the rapid advancement of minimally invasive surgical techniques, laparoscopic cholecystectomy has become one of the most frequently performed procedures worldwide. Despite its benefits, such as reduced postoperative complications and faster recovery, effective pain management remains a critical challenge. Postoperative pain can significantly impact patient recovery, hospital stay duration, and overall satisfaction. Given the limitations and side effects of opioid-based analgesics, there is growing interest in non-opioid alternatives for pain control following laparoscopic cholecystectomy. This narrative review evaluates the efficacy of various non-opioid analgesics in managing postoperative pain in patients undergoing this procedure.
Methods: A comprehensive literature search was conducted across multiple electronic databases, including Scopus, PubMed, Science Direct, SID, Magiran, and Google Scholar, using both Persian and English keywords. English equivalents were "Pain" and "Laparoscopic Cholecystectomy." Studies discussing pharmacological interventions for postoperative pain management in laparoscopic cholecystectomy were included.
Results: The review identified a wide range of non-opioid analgesics used for pain control in laparoscopic cholecystectomy patients. These included: Systemic medications (intravenous/oral) were magnesium sulfate, ketamine, ketorolac, paracetamol, ibuprofen, pregabalin, gabapentin, acetazolamide, N-acetylcysteine, dexamethasone, clonidine, celecoxib, and diclofenac. Local anesthetics & adjuvants were used intraperitoneally like bupivacaine, lidocaine, and hydrocortisone. Administration routes varied, with most drugs given intravenously, intraperitoneally, or preemptively (e.g., celecoxib and clonidine before surgery). Some studies highlighted the benefits of multimodal analgesia, combining different drug classes to enhance pain relief while minimizing side effects.
Conclusion: Despite the availability of numerous non-opioid analgesics, no single drug has been universally endorsed as the gold standard for postoperative pain management in laparoscopic cholecystectomy. Current evidence suggests that the choice of analgesic should be individualized, considering patient factors (e.g., comorbidities, pain tolerance) and the anesthesiologist’s expertise. Multimodal approaches, combining different drug classes, may offer superior pain control with fewer adverse effects compared to monotherapy. Further high-quality randomized trials are needed to establish standardized protocols and optimize pain management strategies for these patients.

Mohammad Saadatnia , Faezeh Sharifi, Fariborz Khoroush,
Volume 83, Issue 8 (11-2025)
Abstract
Background: Subarachnoid hemorrhage (SAH) is a life-threatening emergency condition often accompanied by severe, sudden-onset headache. The main causes are head trauma and aneurysm rupture. Pain management in these patients remains challenging, typically requiring opioids which carry significant adverse effects. As anti-neuropathic agents, gabapentin and pregabalin may serve as suitable alternatives to opioids. This systematic review aimed to evaluate the efficacy and safety of gabapentin and pregabalin in managing SAH-associated headaches.
Methods: Following PRISMA guidelines, we conducted comprehensive searches in PubMed, SCOPUS, Web of Science, and EMBASE through May 2025. Key search terms included "Gabapentin," "Pregabalin," "Subarachnoid Hemorrhage," and "Headache." After initial screening, we selected English or Persian-language articles investigating these medications' effects on SAH-related headache. After removal of duplicates and screening, four eligible studies (including randomized controlled trials and cohort studies) were included for final analysis. Data on study type, sample size, type of interventions, headache management-related outcomes, as well as safety and tolerability profiles were extracted.
Results: Pregabalin demonstrated significant efficacy, showing a statistically significant reduction in pain intensity compared to placebo before anesthesia induction (P≤0.004) and up to 24 hours post-operatively (P=0.007). Additionally, patients receiving pregabalin required significantly fewer rescue analgesics (P≤0.005). In contrast, gabapentin did not produce a statistically significant reduction in pain intensity or morphine equivalent requirements compared to placebo, although a non-significant trend toward decreased pain was observed. Safety profiles were favorable for both medications; no serious adverse events leading to drug discontinuation were reported.
Conclusion: Pregabalin appears to be an effective, safe, and well-tolerated option for managing SAH-related headache, significantly reducing both pain intensity and opioid requirements. Current evidence for gabapentin remains limited and inconclusive, warranting further large-scale, randomized controlled trials to confirm its potential role in this setting.
