Background and Aim: The clinical course of COVID-19 is influenced by various factors. This study aimed to investigate the frequencies of ABO blood groups and their relationship with clinical, and paraclinical findings, severity, and outcomes of COVID-19 in Kashan, Iran. Methods: In this retrospective study, medical records of COVID-19 patients admitted to Shahid Beheshti Hospital in Kashan, Iran, between 2020 and 2022, were reviewed. Demographic data, ABO blood groups, disease severity, clinical course, and outcomes were analyzed. Results: Among 350 COVID-19 patients, 36% had blood group O, 31.4% A, 25.4% B, and 7.2% AB. Only the frequency of cough showed a significant difference among blood groups (P0.05). Conclusion: Despite a higher frequency of blood group O among COVID-19 patients, those with blood group A exhibited higher mortality rates. Clinical symptoms, laboratory results, imaging findings, and other outcomes did not show significant associations with ABO blood groups in COVID-19 patients.

Introduction: Epidural analgesia seems to be one of the most effective methods of controlling labor pain. However, no comprehensive agreement has been reached regarding its side effects. Therefore, the following study was designed to investigate the clinical maternal and neonatal outcomes. Materials and Methods: In a prospective cohort study, from November 2020 to October 2022, 600 primigravid patients were included in two equal epidural analgesia and control groups. The uterine atony, grade 3-4 perineal injury rate, fetal head descent, shoulder dystocia, duration of neonatal hospitalization, cesarean delivery, fever and headache, oxytocin administration, successful breastfeeding, instrumented vaginal delivery, the first-minute Apgar Score were compared between the two groups. The data were analyzed by SPSS-26 with the Chi-square test and T-test. Results: The duration of the active phase, uterine atony, grade 3-4 perineal injury rate and fetal head descent, shoulder dystocia, duration of neonatal hospitalization, and successful breastfeeding between the two groups were not statistically significant(P-value>0.05). Importantly, the incidence of cesarean delivery, fever, headache, and oxytocin administration was significantly higher in the epidural group (P-value <0.05). Regarding the comparison of neonatal outcomes, the use of instrumented vaginal delivery, the first-minute Apgar Score, and the frequency of hospitalization between the two groups were found to be significantly different (P-value 0.03, 0.02, 0.007 respectively). Conclusion: Although the probability of emergency cesarean delivery following epidural labor analgesia increases and the first-minute Apgar score decreases, the serious side effects of epidural labor analgesia seem to be few and its use is effective and safe in reducing labor pain.

Background and Objectives: Scorpion bite is one of the public health problems, which sometimes causes human death. The aim of this study was to determine various epidemiological aspects, clinical signs and outcomes of patients with scorpion bite referred to the emergency of Hazrat Ali Ibn Abitaleb Hospital in Rafsanjan in 2017-2018. Materials and Methods: This descriptive cross-sectional study was conducted in 2017-2018. A total of 59 people stung by scorpion referred to the Emergency Department of Hazrat Ali Ibn Abitaleb Hospital in Rafsanjan were selected through census method. Using a researcher-made checklist, demographic and clinical information were completed by the researchers. Data were analyzed using descriptive statistics (frequency, percentage and mean) and inferential statistics (independent ttest, chi-square or Fisher test). Results: Most scorpion stinges were in people aged 30-39. The highest incidence of scorpion stings was observed by black scorpions with 53 cases (89.8%) from June to August, at 6 pm to 12 pm. The most local clinical symptom with 37 cases (62.7%) was pain and the most systemic clinical symptom was dizziness with 8 cases (13.6%) and hemoglobinuria, the highest laboratory index was 17 (28.8%) cases. A total of 54 cases (91.5%) were discharged after receiving medical treatment in the emergency room. Conclusion: The most common local and systemic clinical symptoms were pain and dizziness, respectively. The hemoglobin index was the most important laboratory indicator and most people were discharged from the emergency room. Preventive training is needed to protect people's health and well-being [ABSTRACT FROM AUTHOR]

Background: We retrospectively compared the clinical outcome of post-cardiac surgery tracheal extubation between patients extubated with a lower than normal pH and patients extubated according to our routine institutional protocol. Our main goal was to clarify that strict adherence to the current criteria is dispensable. Methods: In this retrospective cohort study, we recruited 256 patients who met our study criteria and divided them into the exposed group (n= 95) and the control group (n= 161). The inclusion criteria consisted of coronary artery bypass grafting alone and age> 18 years. The exclusion criteria comprised the use of corticosteroids in the preceding 2 weeks, Serum creatinine (SCr)> 2 mg/dL, uncontrolled diabetes, liver dysfunction, Glasgow coma scale

Introduction: Tele-dermatology is considered by telemedicine service providers about more than a decade. Many reasons, including safety, high diagnostic accuracy compared with physical examination, image-based diagnosis and relatively low cost for installing required systems are making Tele-dermatology successful remarkable. This study introduced Tele-dermatology and its kind and the results of different studies were conducted in clinical area in compare with physical examination is investigated. Method: This review article was done using available library resources and searching online database and articles which published between 2000–2014 in Tele-dermatology field were assessed. Results: Findings showed that, in average the conformity of the proposed diagnosis in skin disease for Tele-dermatology compared with visiting were (79.4 %), for treatment plans were (76.7 %) and reduction of attended visiting was(% 55.6). Also about the servicing fees skin a significant reduction of direct and indirect costs of skin care services show cost- effectiveness of Tele-dermatology. Conclusion: Although most of the researchers and experts agree with the effectiveness of Teledermatology for providing professional health care services and increasing the accessibility of these services, this method is not the final solution to overcome all difficulties related to the shortage of human and financial resources in healthcare system. It should be considered as a complementary to resolve some problems in providing high quality healthcare.

Background: We retrospectively compared the clinical outcome of post-cardiac surgery tracheal extubation between patients extubated with a lower than normal pH and patients extubated according to our routine institutional protocol. Our main goal was to clarify that strict adherence to the current criteria is dispensable. Methods: In this retrospective cohort study, we recruited 256 patients who met our study criteria and divided them into the exposed group (n= 95) and the control group (n= 161). The inclusion criteria consisted of coronary artery bypass grafting alone and age> 18 years. The exclusion criteria comprised the use of corticosteroids in the preceding 2 weeks, Serum creatinine (SCr)> 2 mg/dL, uncontrolled diabetes, liver dysfunction, Glasgow coma scale <13, and acetazolamide and sodium bicarbonate use. The arterial blood gas (ABG) characteristics before and 6 hours after extubation, extubation failure rate, length of stay in the in ICU, length of stay in the hospital and mortality were compared between the two groups. Results: In the control group, the males outnumbered the females and the ejection fraction was higher relative to that in the exposure group (P= 0.01 and P= 0.02, respectively). There were more patients with chronic obstructive pulmonary disease in the exposure group (P< 0.005) and also the euroSCORE was higher (P< 0.002). There were no significant differences between the groups regarding the ABG values at the time of ICU admission. Significantly higher levels of FiO2 and PaCO2 (P< 0.001 for both) as well as lower HCO3 and pH (P< 0.001 for both) were observed in the exposure group immediately before extubation. Following extubation, there was a significant increase in pH and a significant reduction in FiO2 need in the exposure group (P< 0.001 for both). The extubation failure rate, length of stay in the in ICU, length of stay in the hospital, and mortality rate were not different between the 2 groups. Conclusion: The patients with a lower than normal pH, tracheal extubated at the discretion of the ICU anesthesiologist did not have a clinical outcome worse than that of the patients extubated in accordance with our routine institutional protocol.
