Abstract Background Osteoporosis is one of the most common metabolic diseases that is characterized by a decrease in bone density and a loss of the quality of the bone structure. The use of deep learning in the prediction of osteoporosis can provide a non-invasive, cost-effective, and efficient approach. The aim of this study is to investigate the diagnostic accuracy of deep learning in the prediction of osteoporosis. Methods This is a systematic review and meta-analysis study that was conducted on the diagnostic accuracy of deep learning algorithms for predicting osteoporosis. A literature search was performed in electronic databases including PubMed, Elsevier, and Google Scholar to identify relevant articles until December 1, 2023. Articles were searched in databases by combining related terms such as “deep learning”, “convolutional neural network”, and “osteoporosis”. We conducted title, abstract, and full-text screening based on inclusion/exclusion criteria. Various metrics, such as sensitivity, specificity, and area under the curve (AUC), were used to assess the diagnostic performance of deep learning models. Results Out of the 181 articles initially identified, 10 studies were included in the analysis. All studies used a convolutional neural network (CNN) as the deep learning model. Three studies investigated multiple deep learning models. Eight studies used various architectures of CNN, such as ResNet, VGG, and EfficientNet. The pooled sensitivity and specificity were 0.86 (95% CI, 0.82–0.89) and 0.89 (95% CI, 0.85–0.91), respectively. The bivariate approach’s pooled SROC curve produced an AUC of 0.94 (95% CI 0.91–0.95). The Diagnostic Odds Ratio (DOR) for the deep learning models was 49.09 (95% CI, 28.74–83.84). Deeks’ funnel plot asymmetry test (P = 0.4) suggested no potential publication bias. Conclusions Deep learning has an acceptable performance for the diagnosis of osteoporosis, even better than other ML algorithms. However, further research is needed to validate the findings of this study in clinical trials.

Introduction: Antibiotic arbitrary use by increasing resistance changed to a growing issue in the 21st century and its optimal use in hospital could be essential for reducing health system costs and drug side effects. Objectives: The aim of this study was to investigate the pattern of antibiotic use in prescribed prescription. Patients and Methods: This was a cross-sectional study that has been done on 300 prescriptions which selected randomly form Ardabil city hospitals. The anatomical therapeutic chemical classification system with defined daily doses (ATC/DDD) standard measurement method recommended by World Health Organization (WHO) was conducted in the study. The amount uses rate of each medication calculated by DDD/100 bed days. Data collected by a checklist and analyzed by statistical methods in SPSS version 21. Results: The highest prescribed antibiotic was ciprofloxacin with 32% and the total antibiotics uses rate during study period was 44/95 DDD/100 Bed days. The mean number of drugs and prescribed antibiotics in intensive care unit (ICU) ward was more than other wards. However, comparing the rate of antibiotics use between wards based on ATC/DDD method showed that the infection ward with 62.9 was more than other wards. The most form of used antibiotics with 69% was in the form of Ampule and in intravenously method with 64% in all wards. Conclusion: The results of this study showed that the most used antibiotics by considering the studied method, prescribed dose and the hospitalized days were in internal and surgery ward respectively but according ATC/DDD method the most used antibiotics was in infection ward.

Background: Epilepsy is the second, most common and most dangerous neurological complication that can occur in a pregnant woman. Women with epilepsy (WWE) are at higher risk for miscarriage, prematurity, congenital anomalies and low birth weight (LBW). Objectives: The aim of this study was to investigate the outcome of pregnancy in women with epilepsy. Methods: This descriptive study was conducted on 131 pregnant women with epilepsy who referred to Ardabil Alavi Hospital from September 2019 to September 2021. Necessary information such as BMI, type of seizure, congenital malformation, treatment drug and name of used drugs collected through patients file by a checklist and then analyzed by using statistical methods in SPSS version 25. Results: The frequency of neonate term birth was 83.21% and preterm birth was 16.79%. The frequency of babies with LBW was 22.85%. Most of women with 65.96% had cesarean delivery. More than 83% of seizures were generalized and 67.93% used mono-therapy. Only one fetus had malformation (0.76%). The most frequency among the patients receiving mono-therapy was related to the carbamazepine with 26.71% and among the women treated with multitherapy was related to Levetiracetam plus carbamazepine with 12.97%. Conclusion: Pregnancies with epilepsy, even in cases with multidisciplinary care and no other risk factors, are still significantly associated with higher adverse outcomes.

Background: Beta-thalassemia is one of the most common genetic diseases with autosomal recessive inherited patterns in the world and is one of the most common diseases in Iran that exists in all age and sex groups. Determining gene mutations in this disease can be effective in controlling and treating the disease. The present study determined the frequency of polymorphisms of Hinc, RSaI, RDB, and Xmn in patients with beta-thalassemia minor in Ardabil province. Methods: 53 beta-thalassemia patients referred to the genetic department of Imam Khomeini Hospital were studied. Blood samples were taken to determine the type of gene mutation. PCR samples were genetically evaluated to determine genetic mutations using RDB-Sequence-RFLP-Haplotype methods. Results: A total of 53 samples were examined, of which 56.6% were male and the rest were female. The most positive cases in the first and second ranks were related to XmnI and AvaII enzymes with 73.5% and 60.3%, respectively. The most common mutation extracted in the studied samples with 14 cases (26.4%) was IVS2.1. Among the most common mutations extracted by the RDB method was related to IVS 1.2 with 26.4%. Conclusions: The results of the present study showed that the distribution of genetic mutations in the studied samples can be different from other places. Also, by performing targeted genetic counseling, it is possible to control and prevent the disease in the future.

Background: Currently there are several treatment plans for prophylaxis of vestibular migraine, but these treatments are based on physician's observations and there have not been studied on a consensual treatment plan. Objective: Based on diagnostic criteria, we collected vestibular migraine patients and created an individualized treatment plan for 3 months to interpret treatment results. Methods: In this prospective cross-sectional study, 28 patients with headache and dizziness diagnosed for vestibular migraine were enrolled. Demographics, clinical picture, and treatment results were evaluated for all patients at baseline and after three months follow-up duration. Collected data analyzed by statistical methods in SPSS. Results: Due to results, all of the patients with vestibular migraine were female and mostly were in the 30 to 50 years old age group. Dizziness, Headache before vestibular symptoms, increased intensity of headache on excretion, intermediate to high migraine intensity, and throbbing pain were the most common symptoms in the patients. The most common drugs used in the treatment were somatriptan, topiramate and Magnesium+Vitamin B6. After 3 months of treatment, duration, intensity, and frequency of migraine and frequency of dizziness episodes were significantly decreased but there was not a significant relationship between treatment plan and dizziness episodes in terms of duration and intensity. Conclusion: Effectiveness of the drugs in decreasing dizziness episodes can be explained by the effect of the drugs in preventing migraine episodes, whereas in recent studies non-pharmocologic treatments have had a significant effect on decreasing dizziness intensity and duration. Using both pharmacologic and non-pharmocologic methods in combination, is recommended for the treatment of the vestibular migraine.

Background and Objective: Alpha-thalassemia (α-thal) appears to be the most common monogenic disorder worldwide. The diagnosis of α-thalassemia depends on the detection of Hemoglobin Bart (Hb Bartchr('39')s) in newborns, which indicates one or more defective or absent α-globin genes. In addition, in patients with Hemoglobin H (Hb H), the Hb H range usually varies between 7-10 g / dL. Therefore, tracking Hb Bartchr('39')s and Hb H can be useful in diagnosing thalassemia α. This study was performed to evaluate Hb Bartchr('39')s and Hb H in infants with α thalassemia in Ardabil province, northwestern Iran. Material and Methods: In this cross-sectional descriptive study, 33 infants with alpha thalassemia mutation, including infants born in Ardabil province, Iran in the years 2020 to 2019. Hemoglobin analysis was performed by capillary electrophoresis system. Results: Hb H and Hb Bartchr('39')s were detected in only two cases (6%) and three cases (9%). In this study, only 5 patients (15.15) were observable by detection of Hb Bartchr('39')s and Hb H levels by electrophoresis. In cases of Hb Bart disease, -α3.7 was the most common genotype. Therefore, most infants with alpha thalassemia were lost when electrophoresis alone was used. Conclusion: This study showed that molecular analysis of Hb Bartchr('39')s newborns is necessary to confirm α-thalassemia. Capillary electrophoresis is a way to prevent the diagnosis of rare Hb H and Bartchr('39')s disease.

Background: Breast cancer (BC) is the most prevalent cancer in women and the second most common cancer in the world. Two million new cases were reported in 2018. The aim of this study was to investigate the changing trend of BC in the people of Ardabil during 2003-2016. Method: In this cross-sectional descriptive study, we analyzed BC incidence rates using population-based cancer registries stratified by city, age group, gender, and disease grading. We analyzed the collected data by statistical methods in SPSS version 21. Results: The mean age of patients was 48.4±13.1. Of all patients, 98.5% were female, and most were aged 40-60 (56%). The most of BC cases was registered in year 2011 with the most incidence rate about 10.41 per 100000 and the most of cases with 71.5% was registered in Ardabil city. The incidence rate of BC reached from 4.13 per 100000 in 2003 to 6.93 in 2016. The annual percentage change during the study years was 4.1%. Conclusion: Results showed that the incidence rate of BC during study years had an increasing trend in Ardabil’s people and reached from 4.13 per 100000 in year 2003 to 6.93 per 100000 in year 6.93 with Annual percentage change about 4.1%. The trend of BC incidence increased during 2003-2011 and then, decreased during 2011-2016.

Glucose-6-phosphate dehydrogenase (G6PD) is one of the most common genetic deficiencies that affect approximately 400 million people worldwide. This study aimed to identify neonates with G6PD deficiency in Ardabil province during 2017-2018. This cross-sectional study was conducted on all term and preterm newborns in Ardabil Province from April 2018 to April 2019. The sampling method was census and in study duration, 1044 newborns were entered in the study. For each infant, severe hyperbilirubinemia (total serum bilirubin equal or greater than 300 micromol/L) was tested by the diazo method and G6PD was evaluated by Fluorescent Spot Test (FST). Of all infants, 15 (1.4 %) were diagnosed to have G6PD deficiency by FST. The prevalence of G6PD deficiency was significantly in boys higher than in girls (80% vs. 20%, p=0.001). Of all infants, 97 (9.3%) had jaun dice 72 hours after birth that of them 7 neonates (7.2%) had G6PD deficiency. Results showed that the prevalence of G6PD deficiency in this study was less than in other places in Iran that may be because of different ethnicity and demographic features.

Introduction: Early arrival of patients with acute ischemic stroke to start of treatment by recombinant tissue plasminogen activator (rt-PA) within 4.5 hours after onset of stroke. We aimed to develop a machine learning method to predict effective factors on arrival time of patients with stroke to hospital after symptom onset. Methods: We included 676 patients with ischemic stroke who referred to Ardabil city hospital a province in northwest of Iran at year 2018. Classification models such as Random forest (RF), Gradient Boosting Classifier (GB), Decision Tree Classifier (DT), Support-Vector Machines (SVM), Naïve Bayes (NB), artificial neural networks (ANN), and logistic regression (LR) with 10-fold cross-validation were developed to predict effective factors on arrival time of patient with stroke to hospital. The performances were evaluated with accuracy, sensitivity, specificity, positive prophetical worth, and negative prophetical worth. Results: Of all patients, 25.3% arrived to the hospital in less than 4.5 hours. The accuracy of RF, NB, ANN, GB, DT, SVM, LR and suggest method (Stacking) were 0.98, 0.72, 0.73, 0.79, 0.98, 0.73, 0.74, and 0.99. Conclusion: In this study, the Stacking technique provide a better result (Accuracy 99.51%, sensitivity 100%, and specificity 99.40%) among all other techniques and this model could be used as a valuable tool for clinical decision making.

Retinopathy of prematurity (ROP), which affects the retina of premature infants, is a leading cause of blindness in premature infants worldwide. The aim of this study was to evaluate the frequency and risk factors of retinopathy of prematurity infants referred to Alavi hospital between October 2018 and October 2019. In the present study, 400 infants with gestational age less than 34 weeks and or birth weight of 2000 g or less were enrolled in the study. Required information including sex, gestational age, maternal age, birth weight, type of delivery, oxygen therapy, septicemia, multiple gestations, consanguineous marriage, respiratory problem, and blood exchange were extracted from their hospital records and then included in the data collection form. These infants were also examined for ROP, stage and area of involvement by an experienced ophthalmologist and then classified into two groups including retinopathy and healthy group. Finally, the data were analyzed in SPSS 25 software using chi-square, fisher exact test, t-test, binary logistic regression, and ROC curve analysis. Of the 400 preterm infants studied (57.2% male and 42.8% female), 107 (26.8%) infants had ROP of whom 23 (21.5%) needed treatment (i.e. 5.8% of all infants need treatment). There were 4 (3.7%), 29 (27.1%), and 74 (69.2%) infants with zone I, II, and III, respectively. There were 91 (85%), 11 (10.3%), and 5 (4.7%) infants with stage I, II, and III, respectively. Multivariate logistic regression analysis showed that parental consanguinity (OR=2.263, 95%CI: 1.240-4.130, P=0.008), gestational age less than 32.5 weeks (OR=4.067, 95%CI: 2.340-7.069, P

Introduction: About one third of the world's population is infected with tuberculosis (TB) and each year, about 1.5 to 2 million people die from TB. Procalcitonin (PCT) is an inflammatory marker that its level has variable results. There are some discussions in the utilization of PCT as a diagnostic marker in active pulmonary TB. The aim of this study was to compare serum PCT before and after treatment in patients with pulmonary TB. Materials and Methods: This conducted on patients with pulmonary TB. Data were collected using a check list. The serum level of PCT was measured by ELISA test at the beginning and after six months of treatment. All data were analyzed using SPSS 16. Results: Forty-two patients with active pulmonary TB entered in this study. The mean age of the patients was 45.48 ± 12.54 years and 54.8% of them were male. Most of the patients (59.5 %) were rural inhabitants. There was a family history of TB in 26% of patients. The most common symptom (45.2%) was cough. Mean PCT prior to treatment was 1.25 ± 0.98 ng/ml. and 81% of the patients had PCT higher than 0.5 to 5. After treatment PCT level reduced significantly (P

Introduction:Most women have experienced child birth and its pain, which is inevitable. If this pain is not controlled it leads to prolonged labor and injury to the mother and fetus. This study was conducted to identify the effect of acupressure on sanyinjiao and hugo points on delivery pain in nulliparous women. Methods:This was a randomized controlled clinical trial on 84 nulliparous women in hospitals of Ardebil, Iran. The participants were divided by randomized blocks of 4 and 6 into two groups. The intervention was in the form of applying pressure at sanyinjiao and hugo points based on different dilatations. The intensity of the pain before and after the intervention was recorded by visual scale of pain assessment. To determine the effect of pressure on the intensity of labor pain, analytical descriptive test was conducted in SPSS (version 13). Results:There was a significant decrease in mean intensity of pain after each intervention in the experimental group with different dilatations (4, 6, 8, and 10 cm). Moreover, the Student’s independent t-test results indicated that the mean intensity of pain in the experimental group after the intervention in all four dilatations was significantly lower than the control group. Repeated measures ANOVA test indicated that in both experimental and control groups in four time periods, there was a statistically significant difference. Conclusion:Acupressure on sanyinjiao and hugo points decreases the labor pain. Therefore, this method can be used effectively in the labor process.
