Abstract
Introduction: One of the common undesirable postural abnormalities that poor mobility has brought to humans due to the significant growth of technology and widespread use of tools and communication devices is the excessive increase of the back arch (hyperkyphosis) and forward head deformity. Therefore, the aim of this research is to review the effects of rehabilitation exercises on people with kyphosis and forward head posture.
Methods: The current study was a systematic review, searching for articles in Persian and Latin from the beginning of December 2005 to the beginning of April 2023, using the Wos, SID, Magiran, Scopus, ISC, PubMed and Google Scholar databases.
Results: A number of seven articles in the field of rehabilitation exercises reported that corrective exercises improve forward head and kyphosis, as well as posture. One article indicated that the use of braces reduced trapezius muscle electrical activity in patients with kyphosis, which may delay fatigue onset.
Conclusions: : The current review study showed that exercise protocols improve kyphosis and forward head complications, as well as improve pain and maintain proper posture in affected individuals.

Abstract
Introduction: Maintaining general health and preventing occupational burnout are two fundamental components of individuals' lives, and each can influence the other. Therefore, the present study aims to investigate the relationship between occupational burnout and general health among emergency medical technicians (EMTs).
Methods: This descriptive-analytical study was conducted on 150 EMTs from Qom University of Medical Sciences in 2020, who were selected by a simple random sampling method. Data were collected using the Maslach Burnout Inventory and the Goldberg General Health Questionnaire. Data analysis was performed using descriptive statistics and Pearson correlation coefficient.
Results: Based on the findings of the present study, the average age of participants was 35.14 ± 8.09 years. The average scores for occupational burnout and general health were 57.98 ± 19.28 and 48.26 ± 10.97, respectively. Pearson correlation analysis revealed a significant relationship between occupational burnout and general health (r = 0.613, P < 0.001)
Conclusions: Based on the findings of the present study, occupational burnout and general health among the EMTs were at a moderate level. Higher burnout scores were associated with worsened general health disorders among EMTs. It seems that selecting students interested in prehospital emergency professions can enhance the situation of this feeling in individuals working in this field. Additionally, it is essential for prehospital managers to pay attention to the occupational burnout and general health in order to improve the quality of services provided by the EMTs.

Abstract
Introduction: The age structure of the population has changed due to a decrease in mortality rates. With the increase in the number of elderly individuals, addressing their physical, mental, and social needs has become essential. It is necessary to have a reliable and valid tool for assessing the health status of this group for developing future policies and planning health interventions. This study aimed to evaluate the psychometric properties of Lali’s Healthy Lifestyle Questionnaire using Item Response Theory (IRT) among the elderly in Karaj City.
Methods: Data collection was done through the distribution of questionnaires and interviews with patients in the health centers of Karaj city. In addition to demographic information, Lali's Healthy Lifestyle Questionnaire (2012) was used to collect data.
Results: The mean (standard deviation) age of the participants in the study was 66.82 (6.59) years. Based on the Akaike Information Criterion (AIC), the Nominal Response Model (NRM) demonstrated a better fit to the data among the common IRT models for Likert-scale questionnaires. Based on this model, out of the 54 items used, 6 items did not meet the acceptable criteria for the discrimination parameter and were excluded from the questionnaire. Based on the total information function, the questionnaire can appropriately differentiate individuals within the ability range of -1.5 to 2.5.
Conclusions: Using Item Response Theory in questionnaire psychometrics helps to reduce the number of unrelated items and increase the accuracy of the measurement tools.

Abstract
Introduction: The difference in altitude due to the foot's arch in individuals with pes cavus affects transitional movement parameters and may increase the risk of injury. Therefore, the aim of this study is to examine rehabilitation exercises on the mechanics of transitional movements in individuals with an excessive arch of the foot.
Methods: This study was a narrative review. Articles were searched in both English and Persian languages from April 2015 to September 2024 using databases such as Scopus, PubMed, SID, MDPI, Google Scholar, Web of Science (WOS), and ScienceDirect. Considering the inclusion and exclusion criteria, 68 articles were selected. After a detailed review, 58 articles that did not meet the selection criteria were excluded, and 10 articles were selected for final analysis.
Results: The findings of 5 studies indicated that corrective exercises and rope skipping exercises lead to improved postural control and balance. The results of 2 other studies showed that therapeutic exercises, walking, and running can prevent the occurrence of lower limb injuries. Another study demonstrated that a combination of static stretching and electrical stimulation can be beneficial in managing pes cavus. Additionally, mobilization of the talonavicular and first metatarsophalangeal joints was found to be effective in reducing pain associated with this condition.
Conclusions: It seems that rehabilitation exercises focused on enhancing balance in individuals with excessive foot arch may improve transitional movements, postural control, and reduce the rate of lower limb injuries.

Abstract
Introduction: The emergence of antifungal resistance in Candida albicans diseases poses a threat to global public health. New treatments are needed to target C. albicans and its ability to produce hyphae. The aim of this study was to investigate the potential synergistic effects and antifungal properties of Thymus vulgaris and Trigonella foenum-graecum extracts alone and in combination on C. albicans.
Methods: In this experimental study, extracts of Thymus vulgaris and Trigonella foenum-graecum were prepared using hot water (60 °C) and Soxhlet extraction with methanol (10%). Yeast susceptibility testing was performed according to the Clinical and Laboratory Standards Institute disk diffusion and broth microdilution guidelines. The hyphal model was created in the presence of alcoholic extracts of Thymus vulgaris and Trigonella foenum-graecum alone and in combination. Crystal violet staining, microscopic observation and gene expression analysis were used to evaluate the inhibition of hyphal growth.
Results: The results showed that 90% of the C. albicans isolates were resistant to fluconazole. Aqueous and alcoholic extracts of Thymus vulgaris in combination with Trigonella foenum-graecum showed synergistic, partially synergistic and additive effects. Alcoholic extracts of Thymus vulgaris with Trigonella foenum-graecum alone and in combination have anti-hyphae activity by reducing the percentage of hyphae, reducing the number of planktonic cells and the transition of planktonic cells to hyphae, and down-regulating the Secreted Aspartyl Proteinase 1 (SAP1) gene.
Conclusions: Taken together, these results indicate that extracts of Thymus vulgaris alone and in combination with Trigonella foenum-graecum may offer a potent alternative strategy to combat resistant C. albicans infections and their ability to reduce hyphae formation. Additionally, the SAP1 gene could be a likely target in the synergistic interaction of alcoholic extracts of Thymus vulgaris in combination with Trigonella foenum-graecum against the C. albicans hyphae model.

Abstract
Introduction: Physical and cognitive fitness are crucial in futsal, making the identification of effective training methods essential. This study aimed to investigate the effects of two high-intensity interval training (HIIT) protocols on plasma brain-derived neurotrophic factor (BDNF) levels, working memory, and selected physical fitness factors (aerobic and anaerobic capacity) in adolescent futsal players.
Methods: This semi-experimental study was conducted on 15–16-year-old futsal players from Arak city with at least three years of club experience (approved by Arak University Ethics Committee, code: IR.ARAKU.RCE.1401.027). Twenty-four participants were randomly assigned to HIIT1 (10×1-minute intervals with 1-minute rest) or HIIT2 (3×4-minute intervals with 2-minute rest) groups, training for eight weeks. Aerobic capacity, anaerobic capacity, plasma BDNF levels, and working memory were assessed pre- and post-intervention. Data were analyzed using Paired and Independent T-tests (p <0.05).
Results: The HIIT1 group showed significant improvements in aerobic capacity (p=0.001) and BDNF levels (p=0.001). Similarly, HIIT2 demonstrated significant increases in aerobic capacity (p=0.001), anaerobic capacity (p=0.014), and BDNF levels (p=0.001). Working memory showed no significant changes in either group (p=0.780), with no between-group differences observed.
Conclusions: Both HIIT protocols significantly improved aerobic capacity and BDNF levels, while only HIIT2 enhanced anaerobic capacity. Neither protocol affected working memory. HIIT appears effective for enhancing physiological and physical fitness factors in adolescent futsal players.

Abstract
COVID-19 is caused by SARS-CoV-2 and has been declared a pandemic by the World Health Organization. One of the diagnostic methods is performing a swab test from the nasopharynx, which carries a risk of complications. In this article, we present a patient who developed cerebrospinal fluid (CSF) leakage from the nose following a COVID-19 test. A 54-year-old woman presented with unilateral nasal rhinorrhea after undergoing the swab. A skull base defect was identified on computed tomography (CT) scan. The defect was repaired via an endoscopic approach using periumbilical fibro-fatty tissue. This case highlights the need to standardize protocols for performing swab tests.
