Abstract

Background: Osteoarthritis (OA) is the most common form of arthritis characterized by progressive loss of articular cartilage, causing pain and loss of articular function. High glucose is a crucial inflammatory factor playing a pivotal role in the pathogenesis of OA that induces ROS production. Since most of the current therapies for OA are short-term benefits, hence, there is high demand for finding novel therapeutic agents for OA treatment. Recent studies have demonstrated that mesenchymal stem cells secrete important therapeutic factors that protect chondrocytes. In the current study, we investigated the protective potential of Adipose-derived stem cell conditioned medium (CM-ADSC) as an alternative to cell therapy in high glucose-mediated oxidative stress in C28I2 human chondrocytes.
Methods: This experimental study was performed in the Department of Pharmacology, School of Medicine, Iran University of Medical Sciences, Tehran, Iran from May 2018 to August 2020. Adipose-derived stem cells were cultured until they reached 90% confluence then washed with PBS and cultured in a FBS-free medium for 48 hours. The conditioned medium was collected and centrifuged. The protective effect of the concentration of conditioned medium on high glucose (75mM)-induced oxidative stress in C28I2 cell viability was evaluated by WST-1 assay. Total RNA was isolated from the treated and untreated cells with TRIzol reagent. The mRNA expression of antioxidant enzymes including, glutathione S-transferase-P1 (GSTP1), catalase (CAT), and superoxide dismutase1 (SOD1) was evaluated by reverse transcription-polymerase chain reaction in treatment and non-treatment groups.
Results: Adipose-derived stem cell conditioned medium pretreatment remarkably protected C28I2 cells against high glucose. The expression of mRNA of CAT, GSTP1, and SOD1 significantly increased following treatment with the conditioned medium (50%) for 24 hours in high glucose-exposed cells as compared to the control.
Conclusion: Present study indicates that the Adipose-derived stem cell conditioned medium can reduce oxidative stress. It seems that the conditioned medium may protect cartilage in the progression of osteoarthritis.

Abstract

Background: Some negative psychological factors such as depression, anxiety, and stress have been identified as serious risk factors for the final adverse outcome of ischemic heart disease. Given the high prevalence of psychiatric disorders, in this study, we aimed to determine the relationship between the severity of depression, anxiety, and stress, with nuclear scan results in patients referred to Imam Khomeini Hospital in Urmia.
Methods: In this cross-sectional-analytical study, 163 patients with the possibility of ischemic heart disease from various clinics and medical centers referred to Imam Khomeini Hospital in Urmia for nuclear heart scanning from April to July 1400, were assessed by the DASS-21 questionnaire in terms of depression, anxiety, and stress scores. Finally, the data obtained from the DASS-21 questionnaire, nuclear scan, and demographic characteristics were analyzed with SPSS20 software.
Results: According to the results, the mean age of the patients was 54.78±11.54 years, 73% of whom were women. The prevalence of depression, anxiety, and stress was high (72.4, 80.3, and 59.5%, respectively). Although the prevalence of depression, anxiety, and stress in patients with a negative report of ischemia was higher and evaluated as 73.2, 78.7, and 58.3% respectively, there was not a significant difference with the subjects whose heart scan results were positive (P>0.05). Moreover, a weak positive correlation was observed between the severity of depression, anxiety, and stress with the severity of cardiac ischemia in study patients.
Conclusion: The results of this study revealed that the depressive, anxiety, and stress symptoms in patients before a cardiac nuclear scan are often moderate to mild. Likewise, among the different demographic characteristics of patients, only gender played an important role in these disorders. Regardless of the negative nuclear scan results in most patients (77.9%), the prevalence of these psychological symptoms in the studied patients was high. Therefore, considering the possibility of psychological disorders with clinical manifestations mimicking cardiovascular can prevent additional costs for diagnostic and therapeutic procedures in these patients.

Abstract

Background: Congenital tuberculosis is a rare but serious disease in neonates and infants that often presents with nonspecific respiratory symptoms. Pulmonary involvement in tuberculosis can have similar manifestations to bacterial pneumonia with common microorganisms. In case of failure to respond to treatment in pneumonia,  tuberculosis infection should be considered. The aim of this study was to present a two-month-old infant suspected of bacterial pneumonia, who was ultimately diagnosed with tuberculosis.
Case Presentation: This case report describes a two-month-old infant diagnosed with tuberculosis who presented to the emergency department with severe respiratory distress.  Despite repeated hospitalizations and initial antibiotic therapy, the patient's symptoms did not improve and he was eventually referred to the Children's Medical Center. Chest radiography showed diffuse reticular opacities, alveolar opacities in the lower lobe of the right lung, and parahilar opacities in the left lung. Initial laboratory tests included elevated CRP and ESR levels, elevated white blood cell count, thrombocytosis, and abnormal arterial blood gases. Despite three negative gastric aspirate samples for tuberculosis, bronchoscopy was performed and a Bronchoalveolar Lavage (BAL) sample was sent for Polymerase Chain Reaction (PCR) testing for Mycobacterium tuberculosis, which was positive, confirming the diagnosis of tuberculosis. Careful evaluation of the parents revealed that although they had no respiratory symptoms, the mother had imaging evidence of tuberculosis, and her AFB test was positive. The patient showed significant clinical improvement after starting anti-tuberculosis therapy. A six-month follow-up confirmed complete recovery.
Conclusion: In infants with recurrent pneumonia and failure to respond to initial treatments, tuberculosis should be considered as a possible diagnosis.

Abstract

Background: Intracytoplasmic sperm injection (ICSI) is one of the infertility treatments that may lead to various levels of stress and anxiety in women at different stages. Multiple factors may contribute to these psychological disorders. This study aimed to assess the levels of stress, anxiety, and depression before embryo transfer in women undergoing ICSI.
Methods: This cross-sectional analytical study was conducted from July to October 2024 on 70 women candidates for ICSI at Arash Women's Hospital in Tehran, prior to embryo transfer. Participants were selected through convenience sampling. Inclusion criteria included at least three years of infertility, no background in psychology or attendance in counseling sessions, no major physical or mental illnesses, and no severe stressful events in the past six months (such as the death of first-degree relatives or major accidents). Participants could withdraw from the study at any time. The DASS-21 (Depression, Anxiety, Stress Scale) was used to assess stress and anxiety levels. Based on the DASS-21, stress scores of 0-14 were considered normal or mild, 15-18 mild, 19-25 moderate, 26-32 severe, and ≥33 very severe. For anxiety, scores of 0-7 were considered normal or mild, 8-9 mild, 10-14 moderate, 15-19 severe, and ≥20 very severe. The validity of the tool was confirmed by Antony and validated in Iran by Sahebi.
Results: Among the 70 participants, 92.8% experienced stress and anxiety. The mean stress score was 20.77±4.87, and the mean anxiety score was 11.70±4.23, indicating moderate levels. Women over 42 years old had significantly lower stress scores compared to others (P<0.001). Conversely, women under 30 showed significantly higher anxiety scores (P<0.01). No significant associations were found between stress/anxiety and other demographic or infertility-related factors (P>0.05).
Conclusion: The findings indicate that women undergoing embryo transfer in ICSI procedures commonly experience stress and anxiety. Therefore, appropriate psychological interventions are recommended to support this group during treatment.
