despite the many benefits of dental implants, their cost remains a controversial issue. No study in Iran evaluated the costs and benefits of this treatment accurately, so the present study aimed to investigate the economic burden of implant surgery on the urban households of Ardabil province in 2021.

in this descriptive-analytical, cross-sectional study, the economic burden of implant surgery was estimated using the cost of illness method and human capital method. In this study, based on the content and purpose, the prevalence-based approach was used and a suitable checklist was prepared. The statistical population was patients referred to public and private centers providing dental services in Ardabil city. The sample size was calculated to be 160 people and a random sampling method was used for sampling. . Data analysis was done with SPSS version 21 software and Excel software.

The results of the investigation showed that the total cost of implant surgery per unit was (118680744 Rials), 82.11% of these costs were related to direct medical costs, 10.92% were related to non-medical direct costs, and 6.97% were related to indirect medical expenses. Also, the economic burden of implant surgery on Ardabil society was estimated at 71 trillion 467 billion 62 million 235 thousand 635 Rials.

Implant surgery imposes a huge cost on society, so by planning the essential preventive tooth decay strategy, the economic burden imposed by implant surgery on the society of Ardabil can be reduced in the future.

Photogrammetric analysis of facial soft tissue plays an important role in facial plastic surgeries. In many countries, planning for facial plastic surgery is done based on the defined facial metric standards for the same society. Few research works have been conducted in the field of facial cephalometric criteria of the Iranian race. The main goal of this study is to determine the average values of facial profile view metrics of people referred to Imam Reza Hospital (Ardabil).

First, in a period of 3 months, facial profile view images of the referred patients including 30 males and 30 females were provided. Then, the angular criteria of the profile view were measured by selecting 11 facial anatomical landmarks applicable for Rhinoplasty and Mentoplasty surgeries in the MATLAB software.

The results showed that among the facial profile view metrics, the Nasofrontal, Nose Tip and Mentolabial angles are close to the criteria of the Turkish, Nepalese and Brazilian races, respectively. The Facial Convexity Including Nose (FCIN) metric is close to the Brazilian and Nepalese races, and also, Facial Convexity Excluding Nose (FCEN) is close to the Bangladesh and Brazilian races.

In this study, cephalometric analysis of facial soft tissue was done by measuring the facial profile view metrics to help facial plastic surgeons. Considering the difference in facial metrics of Iranians with other races, the criteria measured in this study can be interesting for surgeons in planning of facial cosmetic surgeries, especially Rhinoplasty and Mentoplasty.

Anterior cruciate ligament reconstruction (ACLR) reestablishes electromyography activity during moderate activities such as walking but it is unclear whether this is also the case in sports activities such as running. Therefore, the present study aimed to evaluate the acute effect of using anti- pronation insoles on muscle frequency content in an individual with anterior cruciate ligament reconstruction with pronated feet during running.

The sample of this study consisted of 13 individuals with both ACLR and pronated feet aged 23.2±4.5 years and 13 healthy ones aged 22.9±4.1 years. During both Pre and Post-tests, participants ran barefoot on an 18-m runway at a constant speed of 3.3±5 m/s. The electromyography activity of the lower limb muscles was recorded during running with and without anti-Pronation insoles. Two-way ANOVA with repeated-measures test was used for statistical analysis.

The results indicated greater vastus medial frequency content in ACLR with the pronated feet group than that the healthy group during the loading phase (p=0.024). Also, results demonstrated that the rectus femoris frequency content was greater at the insole condition compared with and without it during the loading phase (p=0.014).

The results of this research showed a significant change in the activity of the quadriceps, hamstrings, gluteus medius, and gastrocnemius when using anti-pronation insoles in people with anterior cruciate ligament reconstruction and pronate feet. Therefore, it could be useful clinically.

Diabetes is a significant risk factor for postoperative complications and mortality. However, there are different opinions about the relationship between the increase in glycosylated hemoglobin (HbA1c) level and the incidence of surgical complications.

In this retrospective study, 189 diabetic patients referred to Sabalan Hospital in Ardabil who were admitted for surgery were examined in 2021. The data related to demographic information, HbA1c test, postoperative complications, and the outcome of patients’ hospitalization were extracted from the records and entered into the researcher-made checklist. Patients were divided into two groups of uncontrolled diabetes with HbA1c of 7 and above and the controlled diabetes group with HbA1c below 7.

Out of 189 patients included in the study, 97 patients were in the uncontrolled diabetes group, and 92 patients were in the controlled diabetes group. The average age of diabetic patients in uncontrolled and controlled diabetes groups was 58.18±8.91 and 61.84±5.52, respectively. According to the results, surgical site infection and the need for re-surgery during hospitalization showed a significant relationship with an HbA1c level (p≤0.05). Other postoperative complications were not significantly different between the two groups.

It seems logical that elective surgeries should be postponed in HbA1c levels higher than 7% because the presence of high HbA1c levels indicates that the patient’s diabetes is not under control, and as a result, there is a higher probability of chronic complications of diabetes as well as a higher risk for post-operative complications.

Bacterial infections are a major cause of chronic infections and mortality, and antibiotics are the preferred treatment for bacterial infections. However, studies show that widespread use of antibiotics has led to the emergence of multidrug-resistant bacterial strains. Hence, the need to develop new and alternative strategies for the production of effective drugs has become an important issue. Recently, the use of nanotechnology has been widely common in various fields. Materials in the nanoscale have unique physical and chemical properties. Silver nanoparticles have different applications and their antimicrobial properties have been confirmed in several studies. This study aimed to investigate the antibacterial properties of silver nanoparticles synthesized by berberine and Hypericum perforatum extract.

In this experimental study, the antibacterial effects of synthesized nanoparticles on standard strains of Escherichia coli [ATCC 25922], Pseudomonas aeruginosa [ATCC 27853], Klebsiella pneumoniae [ATCC 9997], and Staphylococcus aureus [ATCC 29212] were investigated. The MIC content of silver nanoparticles alone and in combination with berberine and Hypericum perforatum extract was investigated for the studied bacteria using the broth microdilution method.

The results of the evaluation of the minimum inhibitory concentration [MIC] of the synthesized compounds on the studied bacteria showed that the nanoparticles synthesized by berberine and Hypericum perforatum extract had the highest antibacterial effects. However, each of the compounds Berberine and Hypericum perforatum extract alone did not show significant antibacterial properties. The results of this study also showed that the highest inhibitory concentration of nanoparticles synthesized by berberine and Hypericum perforatum extract was related to Pseudomonas aeruginosa [0.0375 mg / ml] and the lowest inhibitory concentration was related to Enterococcus faecalis [0.185 mg/ml].

The results of the present study showed that silver nanoparticles synthesized with berberine and Hypericum perforatum extract have significant antibacterial effects. As a result, nanoparticles, including silver nanoparticles, can become one of the most important alternatives to antibiotics due to their unique properties in targeting bacteria. However, achieving definitive results requires further studies in this area.

Given the high prevalence of obesity and overweight and the detrimental impact on the mental health of affected people, the objective of this study is to examine the effectiveness of narrative therapy on social physique anxiety in obese and overweight women.

The current research was a semi-experimental type, with a pre-test, post-test design with a control group. The study population for this research consisted of all obese and overweight women in Tabriz city in 2023. 30 women were selected by the available sampling method and were randomly divided into two groups: the experimental group and the control group. The experimental group received narrative treatment in 8 sessions of 90 minutes, while the control group did not receive any treatment and was placed on the waiting list. At the end of the treatment period, a post-test was performed in both groups. The Social Physique Anxiety Scale by Hart et al. (1989) was used as the measurement tool. The collected data were analyzed using descriptive statistics (mean and standard deviation) and inferential statistics (covariance test with repeated measures) by SPSS-24 software.

In the pre-test, the mean and standard deviation of social physique anxiety in the experimental group were 44.33±2.289, while in the control group, it was 43.67±3.063. In the post-test stage, the values for social physique anxiety in the experimental group were 36.33±3.117, while in the control group, it was 43.80±3.385. The results indicated the effectiveness of narrative therapy (p<0.001). In the follow-up stages, it was found that the effects of narrative therapy are lasting (p<0.001).

According to the results, it can be concluded that narrative can be an effective method for reducing social physique anxiety in obese and overweight women.

Nosocomial infections are significant parts of the treatment challenges of hospitals. Different species of the Artemisia genus are widely distributed in Iran. The present study aimed to compare the in vitro effects of different aqueous extracts of Artemisia species against nosocomial bacterial strains.  style="font-family:"B Traffic""

 24 different aqueous extracts, including decoctions and infusions were prepared from the aerial parts of Artemisia ciniformis, A. turanica, A. kopetdaghensis, A. khorasanica, A. vulgaris, and A. sieberi. Total phenolic contents were determined by the Folin-Ciocalteu method.  The minimum inhibitory concentration (MIC) values of the extracts against the bacterial strains including Staphylococcus aureus, Streptococcus pyogenes, Acinetobacter sp., Pseudomonas aeruginosa, Enterococcus faecalis, Staphyloccocus epidermidis, Micrococcus luteus, Klebsiella  neumonia and Escherichia coli were measured using the microdilution broth method.

The lowest MIC value was observed for the decoction</span> of A. turanica (0.25 mg/ml) against S. pyogenes. The largest range of bacterial sensitivity (3 strains) was related to the decoction of A. sieberi. The growth of S. epidermidis was inhibited by a larger group of extracts. The highest total phenolic content was recorded for decoction and infusion of A. turanica.

 The decoctions of the aerial parts of A. sieberi and A. turanica were superior to the other extracts in terms of the in vitro antibacterial spectrum and selective potency, respectively.
