Abstract
Background: Thyroid disorders are common among young women, and hypothyroidism ranges clinically from subclinical to overt disease, potentially causing various maternal and fetal complications. Determining the appropriate levothyroxine (LT4) dose during pregnancy is crucial for maintaining maternal euthyroidism and optimising pregnancy outcomes. This study aimed to evaluate the dose requirements of LT4 in pregnant women with and without a prior history of hypothyroidism, and to investigate the association with Thyroid peroxidase antibody (TPO) levels.
Methods: This hospital- and clinic-based study was conducted from September 2022 to March 2023 among 146 pregnant women attending a private clinic or Golestan Hospital in Ahvaz, Iran. A total of 146 pregnant women diagnosed with subclinical hypothyroidism (SCH, n=62) or overt hypothyroidism (OH, n=84) were randomly selected. Participants were divided into groups based on their history of hypothyroidism and received LT4 treatment. LT4 requirements were determined according to trimester-specific TSH ranges: >10 mIU/L or 2.5-10 mIU/L in the first trimester, and 3-10 mIU/L in the second and third trimesters. Data analysis was performed using SPSS version 22, employing descriptive statistics (mean±SD, frequency, and percentage) and analytical tests, including the independent t-test and Mann-Whitney U test.
Results: Pregnant women with overt hypothyroidism showed a statistically significant difference in mean LT4 dose between those with and without a prior history of hypothyroidism (P<0.05). In contrast, no significant difference was observed in LT4 requirements among women with subclinical hypothyroidism. TPO Ab positivity was associated with higher LT4 requirements, particularly in women with overt disease. Dose adjustments were most frequent during the first trimester, with incremental increases observed in subsequent trimesters. These findings support individualized monitoring, iodine testing, adherence checks, and coordinated antenatal endocrinology care to improve maternal and neonatal outcomes.
Conclusion: Following the diagnosis of hypothyroidism in early pregnancy, LT4 dosing should be tailored according to disease severity, prior history of hypothyroidism, TPO Ab status, and study location to ensure optimal maternal and fetal outcomes.

Abstract
Background: This study investigates the use of color filters, which represent a scientific and standardized approach to assist individuals with visual impairment. Although there is no fixed protocol for prescribing color filters, these filters, which are often prescribed by ocular care providers in a trial-and-error manner today, help improve visual performance, control glare, and enhance motor skills in affected individuals. Given the absence of formal guidelines and standardized protocols in this area, this study tested common diseases leading to visual impairment against various color filters.
Methods: The study population consisted of patients visiting the Optometry Clinic of Labbafi Nejad Hospital. Participants were voluntarily referred from retinal and corneal departments to this clinic. This quasi-experimental study evaluated acuity at distance and near and contrast sensitivity function with and without color filters, and compared the results. After analysis, filter(s) suitable for each participant were identified and applied clinically, with one-month monitoring and re-evaluation.
Results: A total of 99 participants (54 male, 45 female) with a mean age of 32.19±15.41 years were included. The results showed that after using color filters, distance visual acuity (BCVA) improved significantly in most diseases (P<0.001). However, in albinism and diabetic retinopathy patients, there was no significant improvement in distance vision. At near distance, there was generally a significant improvement in near vision in most diseases after applying the filters (P=0.001). Exceptions included albinism and glaucoma, where no significant difference was observed (P=0.073). For contrast sensitivity (CSF), most patients showed improvement and increased contrast sensitivity (P<0.001), but this increase was not significant in albinism and glaucoma (P=0.483).
Conclusion: The study suggests that the use of certain color filters in visually impaired patients leads to significant improvements in both distance and near acuity and contrast sensitivity function, potentially enhancing quality of life. Based on the quantitative results, selecting the appropriate filter should be disease-specific and done with greater precision. However, the diversity and severity of diseases, the degree of vision loss, and genetic differences among individuals require greater attention to practical experiences and statements from this patient group. Additionally, patients with more than one ocular condition often changed the type and color of the filter.

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.

Abstract
Background: To improve hemostasis and optimize the healing process, autologous fibrin sealant (FS) has been introduced in selected cases. However, the clinical benefits of FS in sinonasal surgery remain controversial and require further evaluation. This study aimed to investigate the effects of autologous FS on hemostasis, mucosal healing, postoperative clinical outcomes, and recurrence in patients undergoing bilateral FESS, compared with normal saline as the control.
Methods: This randomized clinical trial included 32 patients who underwent bilateral FESS at Ghaem and Imam Reza University Hospitals in Mashhad, Iran, between 2019 and 2021. For each patient, autologous FS was applied to one nasal cavity, while the contralateral cavity received normal saline. Postoperative outcomes including bleeding, crusting, adhesion formation, and infection were assessed at 1 week, 1 month, and 3 months after surgery. In addition, sinonasal symptom burden and endoscopic findings were evaluated using the Sinonasal Outcome Test (SNOT-22) and the Lund-Kennedy endoscopic score, respectively, both recorded preoperatively and three months postoperatively.
Results: Application of autologous FS significantly reduced immediate postoperative bleeding, and no further bleeding events were noted during follow-up. Pain severity was comparable between the two sides. No statistically significant differences were observed in crust formation, adhesion, infection, recurrence, or changes in Lund-Kennedy scores between the FS and control sides (p=0.08, p=0.8, p=0.17, and p=0.14, respectively).
Conclusion: Autologous fibrin sealant reduced early postoperative bleeding without adversely affecting pain control, mucosal healing, or recurrence after FESS. Larger randomized trials with extended follow-up are recommended to determine its definitive clinical value and potential for routine use in surgical practice.

Abstract
Background: Helicobacter pylori (H. pylori) is a human gastrointestinal pathogen that infects more than half of the world's population and leads to chronic gastritis and its role in the development of gastric ulcers, gastric cancer and gastric lymphomas is considered. However, eradication of this bacterium with triple therapy fails in more than 30% of cases. Therefore, efforts to find new treatment methods are increasing. As a result, this study was conducted to evaluate the effectiveness and tolerability of several drug regimens compared to the standard regimen.
Methods: This study is a randomized clinical trial in which patients with Helicobacter pylori infection were randomly selected in the endoscopy department of Amiralmomenin Hospital and the Gastroenterology Clinic of Professor Ghavamzadeh Clinic, Arak from October 2024 to March 2025 and were divided into three groups, including a control group and two intervention groups, with three different drug regimens. Four weeks after treatment, the rate of bacterial eradication in all three evaluation groups was assessed using fecal antigen testing and the treatment results were compared using appropriate statistical analyses.
Results: The frequency of negative test results in intervention group 2 was higher than in control and intervention group 1. (P<0.001) and the rate of Helicobacter pylori eradication was in intervention group 2 (94%), in control group (54%), and in intervention group 1 (20%). The chance of H.P eradication in intervention group 1 decreased by 84% compared to the control group and increased by 10.77 times in intervention group 2 compared to the control group. Also, a significant proportion of H.P eradication success was observed in people without diabetes (p-value = 0.022, Phi = -0.188, n = 150) and the rate of drug side effects was higher in intervention group 2 compared to the other two groups.
Conclusion: This study showed that compared to the standard regimen, a 2-week regimen of amoxicillin, omeprazole, and clarithromycin plus bismuth is a good, potent, and more cost-effective regimen for eradicating Helicobacter pylori.

Abstract
Background: Laparoscopic cholecystectomy is the gold standard for treating gallbladder diseases; however, it is associated with physiological challenges from pneumoperitoneum and specific patient positioning. Positive end-expiratory pressure (PEEP) may mitigate these effects, but the optimal level remains uncertain. This study compared the impact of three PEEP levels on respiratory performance and hemodynamic stability during laparoscopic cholecystectomy.
Methods: This randomized double-blind clinical trial was conducted at Shahid Mohammadi Hospital, Bandar Abbas, Iran, from August 2023 to February 2024. A total of 75 adult patients aged 18-70 years with ASA class I-II scheduled for elective laparoscopic cholecystectomy were assigned to three groups (n=25 each): PEEP 0 cmH₂O (control), PEEP 5 cmH₂O, and PEEP 7 cmH₂O. Standardized general anesthesia and mechanical ventilation with tidal volumes of 6-8 mL/kg were applied. Hemodynamic variables (mean arterial pressure, heart rate) and respiratory parameters (SpO₂, EtCO₂) were recorded before intubation, during intubation, and at 15, 30, and 60 minutes post-intubation, as well as in the recovery room. Arterial blood gas analysis was performed 30 minutes after intubation. Data were analyzed using ANOVA and chi-square tests with a significance level of 0.05.
Results: The mean age of patients was 41.89±11.39 years, and baseline demographic variables showed no significant differences among groups. Oxygen saturation remained above 94% across all time points without intergroup differences. EtCO₂ values differed significantly at 30 minutes (P=0.04) and 60 minutes (P=0.01), with the highest levels observed in the PEEP 7 group and the lowest in the PEEP 5 group. Although mean arterial pressure and heart rate did not show statistically significant variation among groups, the PEEP 7 group demonstrated the smallest postoperative decline in blood pressure.
Conclusion: A PEEP level of 5 cmH₂O offers the most favorable balance between maintaining oxygenation, supporting effective ventilation, and preserving hemodynamic stability during laparoscopic cholecystectomy. This level can be recommended as a safe and optimal ventilation strategy.

Abstract
Background: In general anesthesia, anesthetic agents are administered by inhalation or intravenously, leading to loss of consciousness, immobility, analgesia, and amnesia. In spinal anesthesia, injection of a local anesthetic into the intrathecal space causes sensory and motor block. The aim of this study was to compare the volume of bleeding during cesarean section under general anesthesia and spinal anesthesia.
Methods: This study is a cross-sectional prospective study. The gauzes used were weighed before the operation and bloody gauzes were weighed after the operation. The difference between the weight of bloody and dry gauzes was recorded as the volume of bleeding. This volume was then added to the volume of blood in the suction chamber and the final bleeding volume was estimated.
Results: 70 patients who were candidates for cesarean section were included in the study. The mean age of the patients included in the study was 24.82±4.98 and their mean weight was 77.11±8.97. The mean hemoglobin in the spinal anesthesia group was 91.12±39. Volume of bleeding during cesarean section by spinal anesthesia was significantly less than general anesthesia (P=0.001). Also, the visual estimation of bleeding in spinal anesthesia was significantly lower than general anesthesia (P<0.001). In this study, there was no significant difference between heart rate, systolic and diastolic pressure before and during surgery, and the first- and fifth-minute Apgar scores between the two groups of general and spinal anesthesia.
Conclusion: We found in this study that the volume of bleeding during cesarean section under spinal anesthesia is less than general anesthesia. It is suggested that in future studies, other methods of estimating bleeding such as postoperative hemoglobin reduction, dilution method, atomic absorption spectroscopy and photometry be used. Also, a comparison should be made between the three groups of general, spinal and epidural anesthesia, and the volume of bleeding in each should be checked and the best anesthesia method should be selected for cesarean section.

Abstract
Background: Leishmaniasis is one of the most significant parasitic diseases and is susceptible to secondary bacterial infections, which can result in increased inflammation, delayed tissue repair, and increased drug resistance. Given the importance of this phenomenon, the present study was designed to identify bacterial agents and determine their antibiotic resistance patterns in lesions of patients with cutaneous leishmaniasis.
Methods: The present cross-sectional study was conducted in Dezful, Iran, from May 2022 to December 2022 among 173 patients with suspected cutaneous leishmaniasis. In addition to sampling skin lesions for the diagnosis of leishmaniasis, wound exudates were collected using sterile swabs and cultured on blood agar and MacConkey agar plates. Bacteria were identified by Gram staining and biochemical tests. Antibiotic susceptibility patterns were determined by disk diffusion, according to the CLSI 2024 guidelines. SPSS version 20 software was used for data analysis. In Staphylococcus aureus isolates, methicillin resistance was determined using a cefoxitin disk (30 μg), and vancomycin resistance was determined by broth microdilution. In vancomycin-resistant Enterococcus isolates, a vancomycin disk (30 μg) was used. In Enterobacteriaceae, the extended-spectrum beta-lactamase (ESBL) phenotype was performed using ceftazidime (30 μg) and the ceftazidime/clavulanic acid combination disk (30/10 μg).
Results: Cutaneous leishmaniasis was detected in 65.3% of cases, of which 46 cases (26.6%) had secondary bacterial infection. Staphylococcus aureus (67.4%) and Klebsiella pneumoniae (13%) were the most common isolates. Methicillin-resistant Staphylococcus aureus (MRSA) was detected in 13 cases, accounting for 41.9% of the isolates. The frequency of Multidrug-resistant (MDR) Staphylococcus aureus among leishmaniasis patients was 38.7%, but all isolates were susceptible to vancomycin and teicoplanin. Two ESBL-producing Escherichia coli were isolated from leishmaniasis foot ulcers. Leg and back wounds were more frequently involved in bacterial infection (P<0.05).
Conclusion: Inappropriate environmental conditions and lack of treatment facilities play an important role in the occurrence and exacerbation of infectious leishmaniasis lesions. An integrated treatment approach and medical staff training can improve disease control and wound healing.

Abstract
Background: Dermatomyositis is a rare inflammatory muscle disease with systemic manifestations, in which muscle weakness, dysphagia, and pulmonary and cardiac involvement are common problems. The aim of this report is to examine the challenges and management of general anesthesia in a patient with dermatomyositis with the rare complication of buried bumper syndrome after PEG placement and gallbladder surgery.
Case Presentation: A 53-year-old male patient was referred to the operating room of Seyed al-Shohada Hospital in Jahrom for gallbladder stone surgery due to abdominal pain in April-May 2024. The patient had presented to the hospital approximately one month prior with complaints of myalgia and progressive lower limb weakness. He subsequently developed severe dysphagia. Based on clinical and paraclinical evaluations, a diagnosis of dermatomyositis was ultimately made and confirmed. Due to the swallowing difficulty, a Percutaneous endoscopic gastrostomy (PEG) tube was placed for him. His treatment regimen included high-dose corticosteroid pulse therapy and Intravenous immunoglobulin (IVIG). One month later, the patient was readmitted with acute abdominal pain. Imaging studies revealed multiple gallstones, leading to a referral to a general surgeon for operative management. Additionally, a complication related to the PEG tube, known as Buried Bumper Syndrome, was considered as a potential cause of the abdominal pain. Given the patient's history of dermatomyositis and swallowing disorder, a comprehensive re-evaluation was performed in the operating room. Cricoid pressure (Sellick maneuver) was applied to prevent aspiration. The surgery was successfully completed, and the patient remained hemodynamically stable throughout the procedure.
Conclusion: General anesthesia in patients with dermatomyositis requires careful preoperative evaluation, continuous muscle and hemodynamic monitoring, selection of appropriate doses of muscle relaxants, and use of stress doses of steroids. In addition, attention to specific complications such as buried bumper syndrome after PEG and proper airway management and prevention of aspiration are of particular importance. The present report emphasizes that multifaceted and planned management can lead to successful outcomes in these patients.

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: Postoperative pain remains a major concern following abdominal surgeries, including laparoscopic cholecystectomy. Inadequate pain control may lead to increased opioid consumption, delayed recovery, prolonged hospitalization, and reduced patient satisfaction. Therefore, the use of anesthetic adjuvants with effective analgesic properties and minimal side effects has gained increasing attention. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, and dexmedetomidine, a highly selective α2-adrenergic agonist, are commonly used agents with distinct mechanisms of action. The present study aimed to compare the effects of intraoperative ketamine and dexmedetomidine on postoperative pain following laparoscopic cholecystectomy.
Methods: This randomized, double-blind, controlled clinical trial was conducted on 252 patients undergoing elective laparoscopic cholecystectomy. Patients were randomly assigned into three equal groups: ketamine, dexmedetomidine, and control. The ketamine group received an intravenous infusion of ketamine at a dose of 0.5 mg/kg/h, the dexmedetomidine group received 0.6 µg/kg/min of dexmedetomidine, and the control group received normal saline. Pain intensity was assessed using the Visual Analogue Scale (VAS) at 1, 6, 12, and 24 hours postoperatively. Hemodynamic parameters, including heart rate and mean arterial pressure, were continuously monitored throughout the perioperative period. Data were analyzed using appropriate statistical tests, including ANOVA and nonparametric analyses.
Results: The results demonstrated that postoperative pain scores were significantly lower in the ketamine group compared to both the dexmedetomidine and control groups at all evaluated time points within the first 24 hours after surgery (P < 0.001). Although dexmedetomidine also provided effective analgesia compared with the control group, ketamine showed superior pain reduction. No statistically significant differences were observed among the three groups regarding hemodynamic parameters, indicating comparable cardiovascular stability.
.Conclusion: Intraoperative administration of ketamine was more effective than dexmedetomidine in reducing postoperative pain following laparoscopic cholecystectomy, without compromising hemodynamic stability. Nevertheless, both agents proved to be safe and effective options for postoperative pain management. Ketamine may be considered a preferable.

Abstract
Background: Cisplatin is one of the most effective chemotherapy agents; however, its nephrotoxicity remains the primary dose-limiting factor. This study aimed to determine the prevalence and clinical course of acute kidney injury (AKI) in patients receiving high-dose cisplatin therapy.
Methods: This cross-sectional descriptive study was conducted at Ayatollah Khansari Hospital in Arak, based on clinical records of hospitalized patients from March 2021 to June 2022. Patients who received at least four cycles of cisplatin-based chemotherapy at a dose of 260 mg/m² were included. Data were extracted from the Hospital Information System (HIS) and physical records. Ninety eligible cases were selected via random sampling. Data were summarized using descriptive statistics.
Results: Regarding gender distribution, 54.4% were female (n=49) and 45.6% were male (n=41). The relative frequency of cisplatin-induced AKI was 21.11%. Overall, 26.32% of patients developed chronic kidney disease (CKD), 10.53% reached end-stage renal disease (ESRD), and only 11.42% recovered. An 18 to 24-month follow-up revealed a mortality rate of 21.05%, while 15.79% required treatment modification, and 5.26% needed kidney transplantation. No treatment discontinuation was observed. Logistic regression analysis identified female gender, age 61-70, age >70, poor hydration status, five or more chemotherapy cycles, and diabetes mellitus as significant risk factors for AKI.
Conclusion: High-dose cisplatin is associated with a high risk of permanent renal damage. Given the low recovery rate and the potential for progression to chronic renal failure, careful monitoring of risk factors and rigorous hydration management are vital for these patients.

Abstract

Background: Nonalcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver diseases worldwide and is closely associated with metabolic syndrome and insulin resistance. Growing evidence suggests a link between NAFLD and cardiovascular diseases, independent of traditional risk factors. Coronary computed tomography angiography (CCTA) is a reliable noninvasive method for evaluating coronary artery disease (CAD) and identifying high-risk coronary plaque characteristics. However, data regarding the association between NAFLD and high-risk coronary plaques remain limited, particularly in Iran. This study aimed to evaluate the prevalence of NAFLD in patients with high-risk coronary plaques detected by CCTA. Methods: In this cross-sectional study, 200 patients who underwent CCTA for the evaluation of coronary plaques in outpatient clinics or the emergency department of Golestan Hospital in ahvaz ,1403 ,were enrolled. Demographic data, including age, sex, weight, and body mass index (BMI), along with clinical characteristics and cardiovascular risk factors such as hypertension, diabetes mellitus, dyslipidemia, smoking status, and medical history were collected. Patients with a history of alcohol consumption or known liver disease were excluded. NAFLD was assessed based on imaging findings. Statistical analyses were performed to compare variables between patients with and without NAFLD. Results: The mean age of patients with NAFLD was 57.89 ± 9.72 years, compared with 55.77 ± 8.97 years in patients without NAFLD, with no statistically significant difference. The prevalence of NAFLD was slightly higher in women than men; however, this difference was not significant. Patients with NAFLD had a significantly higher mean weight than those without NAFLD (85.21 ± 12.12 kg vs. 79.62 ± 11.85 kg; p = 0.001). Additionally, the prevalence of NAFLD increased significantly with higher BMI categories, particularly in obese individuals. Conclusion: Age and gender were not significantly associated with NAFLD prevalence in patients with high-risk coronary plaques. In contrast, increased body weight and higher BMI, especially obesity, were independently associated with a higher risk of NAFLD in this population. |
