The relationship among positive body image, body esteem, and eating attitude in Iranian population.

Background and aim: The correlation between eating attitudes, positive body image, and body esteem is a pivotal area of research that has garnered substantial attention in recent years, given its implications for both mental and physical well-being. The objective of this study was to examine the interplay between positive body image, body esteem, and eating attitudes within an Iranian population. Materials and methods: This study employed a cross-sectional study design and was conducted in the year 2022. A convenience sample of 752 participants residing in Tehran, Iran, was included in the study. The data collection tools were comprised of a demographic registration form, the Adolescence/Adults Scale (PBIAS), the Eating Attitudes Test (EAT), and the Body Esteem Scale (BES) as measurement instruments. Results: Mean age of participants was 26.36 (SD = 8.49). Significant relationships were found among positive body image (B = - 0.095, ß = -0.150, p < 0.001), and body esteem (B = 0.175, ß = 0.149, p < 0.001) with eating attitudes. Conclusion: These findings suggest that individuals with positive body image and high body esteem may have healthier eating attitudes, while those with negative body image and low body esteem may be more likely to have unhealthy eating attitudes.

Student satisfaction and academic efficacy during online learning with the mediating effect of student engagement: A multi-country study.

The COVID-19 pandemic caused unprecedented changes to educational institutions, forcing their closure and a subsequent shift to online education to cater to student learning requirements. However, successful online learning depends on several factors and may also vary between countries. As such, this cross-sectional study sought to investigate how engagement of university students, a major driver of online learning, was influenced by course content, online interaction, student acceptance, and satisfaction with online learning, as well as self-efficacy across nine countries (China, India, Iran, Italy, Malaysia, Portugal, Serbia, Turkey, and the United Arab Emirates) during the COVID-19 pandemic. Using a questionnaire-based approach, data collected from 6,489 university students showed that student engagement was strongly linked to perception of the quality of the course content and online interactions (p < .001). The current study also indicated that online interactions are a major determinant of academic efficacy but only if mediated by engagement within the online learning context. A negative correlation between student engagement and satisfaction with online learning was found, demonstrating the importance of students being engaged behaviorally, emotionally, and cognitively to feel satisfied with learning. Academic efficacy and student satisfaction were explained by course content, online interaction, and online learning acceptance, being mediated by student engagement. Student satisfaction and, to a lesser degree academic efficacy, were also associated with online learning acceptance. Overall, the structural equation model was a good fit for the data collected from all nine countries (CFI = .947, TLI = .943; RMSEA = .068; SRMR = .048), despite differences in the percentage variations explained by each factor (no invariance), likely due to differences in levels of technology use, learning management systems, and the preparedness of teachers to migrate to full online instruction. Despite limitations, the results of this study highlight the most important factors affecting online learning, providing insight into potential approaches for improving student experiences in online learning environments.

Effects of COVID-19 on brain and cerebellum: a voxel based morphometrical analysis.

OBJECTIVE: COVID-19 is caused by SARS-CoV-2 virus and turned into a pandemic in a short time, affects many organs and systems, especially the nervous system. In the present study, it was aimed to determine the morphological and volumetric changes in cortical and subcortical structures in recovered COVID-19 patients. BACKGROUND: We think that COVID-19 has a long-term effect on cortical and subcortical structures. METHODS: In our study, 50 post-COVID-19 patients and 50 healthy volunteers participated. In both groups, brain parcellations were made with Voxel-Based Morphometry (VBM) and regions showing density changes in the brain and cerebellum were determined. Gray matter (GM), white matter, cerebrospinal fluid and total intracranial volume were calculated. RESULTS: Neurological symptoms developed in 80% of COVID-19 patients. In post-COVID-19 patients, a decrease in GM density was detected in pons, gyrus frontalis inferior, gyri orbitales, gyrus rectus, gyrus cinguli, lobus parietalis, gyrus supramarginalis, gyrus angularis, hippocampus, lobulus semilunaris superior of cerebellum, declive, and Brodmann area 7-11-39-40. There was a significant decrease in GM density in these regions and an increase in GM density in amygdala (p<0.001). The GM volume of post-COVID-19 group was found to be less than in the healthy group. CONCLUSIONS: As a result, it was seen that COVID-19 negatively affected many structures related to the nervous system. This study is a pioneering study to determine the consequences of COVID-19, especially in the nervous system, and to determine the etiology of these possible problems (Tab. 4, Fig. 5, Ref. 25).

The predictive role of parental attitudes toward COVID-19 vaccines and child vulnerability: A multi-country study on the relationship between parental vaccine hesitancy and financial well-being.

Background and purpose: Recent new mutations and increases in transmission of COVID-19 among adolescents and children highlight the importance of identifying which factors influence parental decisions regarding vaccinating their children. The current study aims to explore whether child vulnerability and parents' attitudes toward vaccines mediate the association between perceived financial well-being and vaccine hesitancy among parents. Method: A predictive, cross-sectional, multi-country online questionnaire was administered with a convenience sample of 6,073 parents (Australia, 2,734; Iran, 2,447; China, 523; Turkey, 369). Participants completed the Parent Attitude About Child Vaccines (PACV), the Child Vulnerability Scale (CVS), a Financial Well-being (FWB) measure, and Parental Vaccine Hesitancy (PVH) questionnaire. Results: The current study revealed that perceived financial well-being had significant and negative associations with parents' attitudes toward COVID-19 vaccines and child vulnerability among the Australian sample. Contrary to the Australian findings, results from Chinese participants indicated that financial well-being had significant and positive predictive effects on parent attitudes toward vaccines, child vulnerability, and parental vaccine hesitancy. The results of the Iranian sample revealed that parents' attitudes toward vaccines and child vulnerability significantly and negatively predicted parental vaccine hesitancy. Conclusion: The current study revealed that a parents' perceived financial well-being had a significant and negative relationship with parental attitudes about vaccines and child vulnerability; however, it did not significantly predict parental vaccine hesitancy among Turkish parents as it did for parents in Australia, Iran, and China. Findings of the study have policy implications for how certain countries may tailor their vaccine-related health messages to parents with low financial wellbeing and parents with vulnerable children.

Golden ratio for the foramen magnum on CT images: a morphological and morphometrical study / Proporción áurea para el foramen magnum en imágenes de TC: un estudio morfológico y morfométrico

SUMMARY: The foramen magnum (FM) is a transition zone between the spine and skull. There is a study in the literature showing the golden ratio (4.62) and harmony between both FM and the anteroposterior and transverse diameters of the skull. The aim of this study is to examine the existence of this ratio on CT images and to investigate whether this ratio changes according to the FM shape types. In this study, 402 adult CT images belonging to the Turkish population were examined. Maximum cranial length (MCL), maximum cranial width (MCW) and the FM length (FML) and FM width (FMW) were measured. The different shapes of the FM were macroscopically classified. The number and incidence of each type in the studied skull was registered. In the 402 CT images used in the study, 12 FM shapes were detected. Three of the shape types observed in our study have not been reported in the literature until now, and were found in our study for the first time. In addition, our data supported that by using the ratio of 4.62, there was a great harmony between the skull and FM. The results obtained from the research show that there is a ratio of 4.62 between the basic cranial measurements and FM dimensions in all shapes except triangular shape. It is thought that repeating the calculated coefficients over more different FM shapes will contribute to the effectiveness of the proposed golden ratio.

RESUMEN: El foramen magno (FM) es una zona de transición entre la columna y el cráneo. Existe un estudio en la literatura que muestra la proporción áurea (4,62) y la armonía entre el FM y los diámetros anteroposterior y transversal del cráneo. El objetivo de este estudio fue examinar la existencia de esta relación en las imágenes de TC e investigar si esta relación cambia según los tipos de forma del FM. Se examinaron 402 imágenes de TC de adultos pertenecientes a la población turca. Se midieron la longitud craneal máxima, el ancho craneal máximo y la longitud del FM y la anchura del FM. Las diferentes formas del FM se clasificaron macroscópicamente. Se registró el número e incidencia de cada tipo en el cráneo estudiado. En las 402 imágenes de TC utilizadas en el estudio, se detectaron 12 formas de FM. Tres de los tipos de formas observados en nuestro estudio no se han reportado en la literatura consultada describiéndose por primera vez. Además, nuestros datos respaldaron que al usar la proporción de 4,62, había una armonía importante entre el cráneo y el FM. Los resultados obtenidos de la investigación muestran que existe una relación de 4,62 entre las medidas craneales básicas y las dimensiones de la FM en todas las formas excepto en la triangular. Se cree que la repetición de los coeficientes calculados en más formas de FM diferentes contribuirá a la eficacia de la proporción áurea propuesta.

Clinical accuracy and agreement between tympanic and forehead body temperature measurements for screening of patients with COVID-19.

AIM: To investigate the accuracy, reliability and agreement between infrared forehead thermometers versus infrared tympanic thermometers temperature, a cross-sectional study was conducted in April 2020. METHODS: The forehead and tympanic temperatures of 615 subjects were measured simultaneously in three exposed SARS-COV-2 groups at one hospital in Iran, during April 2020. These comparisons were evaluated by Bland-Altman Plot, repeatability, Passing-Bablok regression and Lin's concordance correlation coefficient. The receiver operating characteristic (ROC) analysis was done to describe the discrimination accuracy of a diagnostic test. The study adhered to STROBE checklist for cross-sectional studies. RESULTS: A Bland-Altman plot indicated that the limits of agreement between the forehead and tympanic temperature were -0.259 to +0.19°C. Passing-Bablok regression analysis illustrated that the infrared forehead was not linearly related to tympanic temperatures (reference method), with a slope estimate that was significantly different from 1.00. The infrared forehead thermometer showed poor precision and lower accuracy than the tympanic. The forehead temperature readings had 60.0% sensitivity and 44.4% specificity (p > .05) to predict disease. CONCLUSION: According to the results of study, there is no evidence that the assessment of temperature by infrared forehead thermometer could discriminate between the two groups (positive and negative).

Validation of the Persian version of Skindex-16 among older patients with skin diseases.

BACKGROUND: Skin conditions often considerably impact the older patients' psycho-social health and quality of life (QoL). The present study was aimed to examine the validity and reliability of the Persian version of Skindex-16 among older people with skin diseases. METHODS: In this validation study, 260 older patients suffering from a range of skin conditions were recruited from a dermatology clinic in Rasht, Iran. Data were collected using a checklist for demographic and clinical characteristics and the Skindex-16 questionnaire. In this study, validity (face, content, and construct) and reliability (Cronbach's alpha) of the Skindex-16 were assessed and reported. RESULTS: The mean age of participants was 64.51 ± 5.04 years. The results of confirmatory factor analysis showed that the model had acceptable fitness into the expected three-factor structure [χ 2 /df = 249.363, P < 0.001; GFI = 0.961; TLI =0.952; RMSEA = 0.078 (90% CI = 0.06, 0.09) and SRMR = 0.06]. The reliability analysis results confirmed that the values of Cronbach's alpha coefficient for Skindex-16 were in the acceptable range (0.923). CONCLUSIONS: Our evaluation of the Skindex-16 indicates that it is reliable and a valid instrument that can be used for measuring QoL for Iranian dermatologic patients.

A time-series prediction model of acute myocardial infarction in northern of Iran: the risk of climate change and religious mourning.

BACKGROUND: Although various studies have been conducted on the effects of seasonal climate changes or emotional variables on the risk of AMI, many of them have limitations to determine the predictable model. The currents study is conducted to assess the effects of meteorological and emotional variables on the incidence and epidemiological occurrence of acute myocardial infarction (AMI) in Sari (capital of Mazandaran, Iran) during 2011-2018. METHODS: In this study, a time series analysis was used to determine the variation of variables over time. All series were seasonally adjusted and Poisson regression analysis was performed. In the analysis of meteorological data and emotional distress due to religious mourning events, the best results were obtained by autoregressive moving average (ARMA) (5,5) model. RESULTS: It was determined that average temperature, sunshine, and rain variables had a significant effect on death. A total of 2375 AMI's were enrolled. Average temperate (°C) and sunshine hours a day (h/day) had a statistically significant relationship with the number of AMI's (ß = 0.011, P = 0.014). For every extra degree of temperature increase, the risk of AMI rose [OR = 1.011 (95%CI 1.00, 1.02)]. For every extra hour of sunshine, a day a statistically significant increase [OR = 1.02 (95% CI 1.01, 1.04)] in AMI risk occurred (ß = 0.025, P = 0.001). Religious mourning events increase the risk of AMI 1.05 times more. The other independent variables have no significant effects on AMI's (P > 0.05). CONCLUSION: Results demonstrate that sunshine hours and the average temperature had a significant effect on the risk of AMI. Moreover, emotional distress due to religious morning events increases AMI. More specific research on this topic is recommended.

Spiritual Well-Being, Social Support, and Financial Distress in Determining Depression: The Mediating Role of Impact of Event During COVID-19 Pandemic in Iran.

This study investigates the relationship between spiritual well-being, social support, and financial distress with depressive symptoms due to the COVID-19 pandemic. A path analysis was used to analyze data collected from 1,156 Iranian participants via an online survey. The results showed that spiritual well-being and social support were negatively related to depressive symptoms and financial distress. The impact of COVID-19 events showed negative associations with depressive symptoms. In addition, the link between spiritual well-being and financial distress with depressive symptoms was partially mediated by the impact of events.

Ingestion of Cylindrical Battery and Medical Treatment.

Due to their chemical properties, accidental or suicidal ingestion of batteries into the digestive system can cause fatal complications; Treatment should not be delayed and close monitoring is required. A 26-year-old male patient is treated by the psychiatry department with diagnoses of antisocial personality disorder and depressive adjustment disorder. He consulted with the complaint of ingesting cylindrical AA battery for suicidal purpose. In our case, the cylindrical AA battery in the duodenum was removed from the rectum at the end of the third day without any complications. However, the continuous movement of the cylindrical AA battery with lactulose treatment in the gastrointestinal tract and the support of this movement with abdominal radiographs can reduce the risk of fatal complications. When planning the battery treatment in the gastrointestinal tract, the location of the battery and whether it is mobile should be determined. While obstruction of oesophagus by batteries requires emergency surgical treatment, batteries that remained fixed in the stomach for longer than 48 hours need to be treated with surgical or endoscopic methods.

Incidence and mortality results of intestinal obstruction in geriatric and adult patients: 10 years retrospective analysis.

Objectives: People with ileus is one of the patient groups with the highest admission rates to the emergency departments. In this study, it was aimed to determine the effects of age groups and etiological factors on mortality when evaluated together with gender. Material and Methods: In our study, patients who were consulted from the Emergency Service to the General Surgery department with a pre-diagno- sis of abdominal pain between 2009 and 2020 were retrospectively screened. Patients hospitalized for ileus were analyzed in terms of age (18-65 years and over 65 years), gender, operation, etiology, incidence, and mortality. Results: Between 2009 and 2020, 534 (3.03%) of 17.601 patients who received emergency consultation from the general surgery clinic were diagnosed with ileus. While 253 (47.4%) of the patients were operated, 317 (59.4%) patients and 101 (18.9%) patients were diagnosed with brid and malignancy, respectively; and 21 (3.9%) patients died in the complete patient group (Table 1). While the incidence of brid was high in non-operated patients, in operated patients, malignancy and other pathologies was found to be higher (p <0.001) (Table 2). While, in patients 65 years and older, mortality was observed in 10.6% of women and 2.6% of men, it was determined that the mortality rate was higher in women (p= 0.008) (Figure 4). Conclusion: The mortality rate in patients hospitalized with the diagnosis of mechanical bowel obstruction was found to be statistically significantly higher in female patients aged 65 and over.

Is the compressive nail method capable of accelerating bone union in patients with femoral distal diaphysis fracture?

OBJECTIVES: This study was conducted to evaluate clinically and radiologically the patients for whom compressive and non-compressive intramedullary nails were applied and to analyse the compression effectiveness in adult femur distal diaphysis fractures. HYPOTHESIS: The compressive locked nails shortened the union period in the distal diaphysis fractures, and it was found to be an effective method, as the pseudoarthrosis rate was lower. MATERIAL AND METHODS: A retrospective study was conducted among 59 patients for whom the compressive and non-compressive IMNs were applied to treat femur distal diaphysis fractures. Thirty-one for whom the non-compressive IMN was applied were categorised as group I, and 28 for whom the compressive nail was applied were categorised as group II. Finite element analysis was performed using 1.5mm compression, and a mean stress value of 34.67Mpa. RESULTS: The mean values of union period were calculated as 13.6±2.4 weeks (range: 11-20 months) and functional score was 79.2, respectively in group I, and they were evaluated as a good grade. In group II, the respective mean values of union period were 11.5±2.6 weeks (range: 10-17 months) and functional score was 86, and they were evaluated as excellent. CONCLUSION: Radiological and functional scores were determined to be better with interlocking compressive nails and shortened the fracture union period in the follow-up in adult femur distal diaphysis fractures. LEVEL OF EVIDENCE: III; retrospective cohort study.

Retrospective evaluation of the effects of sugammadex and neostigmine on the IgE and eosinophil cationic protein in morbid obese patients.

OBJECTIVE: This study was designed to show that allergic reactions with gamma cyclodextrin-related caused by sugammadex are not anaphylaxis but an anaphylactoid reaction. METHODS: In this retrospective study, 83 morbidly obese patients, who underwent elective laparoscopic sleeve gastrectomy operation, were included. Patient data were obtained from patient files and electronic health records system (SARUS). The patients were divided into two groups as sugammadex (Group S) and neostigmine (Group N). Patient data were recorded, including patient preoperative demographics (age, gender) and preoperative and postoperative (12 hours later) levels of total IgE and ECP (Eosinophil cationic protein) levels. RESULTS: There was not a significant change in the total IgE levels in Group S or Group N (p>0.05); however, the levels of ECP significantly decreased in both groups (p<0.001, p=0.01). In the patients in Group S, the preoperative levels of total IgE were significantly positively, and weakly correlated with the preoperative ECP (p=0.311, p=0.045) and postoperative ECP (p=0.310, p=0.046) levels. CONCLUSION: Allergic reactions that arise from sugammadex related with gamma-cyclodextrin are non-IgE mediated anaphylactoid reactions. Anaphylactoid reaction was not observed after administration of 2 mg kg-1 sugammadex intravenously in patients with morbid obesity.

Effects of Comorbid Factors on Prognosis of Three Different Geriatric Groups with COVID-19 Diagnosis.

Coronavirus disease 2019 (COVID-19) is a new zoonotic infectious disease that was first reported to the World Health Organization (WHO) on December 31, 2019, and declared as a pandemic by WHO on March 11, 2020. Due to the increased incidence of multimorbidity in geriatric age groups, COVID-19 disease leads to more severe consequences in the elderly. We aimed to determine the effects of age, comorbidity factors, symptoms, laboratory findings, and radiological results on prognosis by dividing our patients into 3 different geriatric age groups, using a retrospective descriptive analysis method. Patients included in the retrospective study (n = 483) were divided into the following three different geriatric age groups: young-old (65-74 years), middle-aged (75-84 years), and the oldest-elderly (85 years and over).The length of stay in the intensive care unit of the patients between the ages of 75-84 was higher than the other two groups (p = 0.013). Mortality rates were lowest in patients aged 65-74 years (p < 0.001). The rate of ground glass opacity in thorax CT was higher in patients with mortality (p < 0.001). While the rate of COPD-bronchial asthma was higher in surviving patients (p = 0.001), malignancy (p = 0.005) and cerebrovascular disease (p < 0.001) were higher in patients who died. Patients aged between 75 and 84 (OR: 2.602; 95% CI: 1.306-5.183; p = 0.007) or ≥ 85 (OR: 4.086; 95% CI: 1.687-9.9; p = 0.002) had higher risk for mortality compared to patients aged between 65 and 74. The lowest mortality rates were observed in patients aged 65-74 years. Among the supportive diagnostic methods in 3 different geriatric age groups, PCR positivity has no effect on mortality, while the ground glass opacity on tomography is closely related to the need for intensive care and increased mortality. In patients with COPD-bronchial asthma comorbidity and those with symptoms of fatigue, dry cough, and sore throat, transfer to intensive care and mortality rates were lower, while patients who were transferred to intensive care and who developed mortality had higher malignancy and cerebrovascular disease comorbidities and dyspnea symptoms.

rRT-PCR Results of a Covid-19 Diagnosed Geriatric Patient.

In this study, we aimed to present a geriatric patient with the diagnosis of COVID-19 and with contradictory results in rRT-PCR examinations in short time intervals. A 69-year-old male patient was admitted to the emergency room on the 18th day of May 2020, with the complaints of fever, sweating, myalgia, dry cough that continued for 5 days, and the lack of taste that started on the day he applied to the emergency room. Comorbidity factors include diabetes mellitus, bronchial asthma, and hypertension. The patient has a history of 36 years of smoking 1.5 packs per day. High laboratory findings during hospitalization: monocytes, creatinine, CRP (C-reactive protein). In the thorax CT, in the parenchyma areas of both lungs, there are increases in attenuation with multilobe distributions (more visible at the level of the upper lobes) in the form of ground-glass opacities. May 19, 2020, was subjected to the rRT-PCR test, repeated twice on the 19th of May which also resulted in positive. Despite rRT-PCR tests, which were negative on 27th of May and positive on 28th of May, the patient, whose symptoms disappeared, and general condition improved, was discharged on June 1, 2020, with the recommendation for home isolation. In our case, unlike the incubation period only, we encountered a negative rRT-PCR result on the 8th day after diagnosis. Therefore, the COVID-19 pandemic control and filiation evaluation with the rRT-PCR test may produce false negative results.

Prevalence of Acute Myocardial Infarction and Changing Meteorological Conditions in Iran: Fuzzy Clustering Approach.

BACKGROUND: The prevalence of Acute Myocardial Infarction (AMI) varies from region to region caused by seasonal climate changes and temperature variation. This study aimed to assess the relationship between changing meteorological conditions and incidence of AMI in Iran. METHODS: This retrospective prevalence study was based on medical records of the heart center of Mazandaran Province on all patients diagnosed with AMI in Mazandaran, northern Iran between 2013 and 2015. Patients' sex and the day, month, year and time of hospital admission were extracted from patients' records. Moreover, the meteorological reports were gathered. RESULTS: A statistically significant difference was found between the distributions of AMI cases across 12 months of the year (P < 0.01). Fuzzy clustering analysis using 16 different climatic variables showed that March, April, and May were in the same cluster together. The other 9 months were in different clusters. CONCLUSION: Significant increase in AMI was seen in March, April and May (cold to hot weather).

Validity and Reliability of the Flourishing Scale in a Sample of Older Adults in Iran.

BACKGROUND: Flourishing is related to positive outcomes for physical and mental health, as well as overall wellbeing. The aim of the present study was to determine the validity and reliability of the Flourishing Scale (FS) among a sample of older participants in Iran. METHODS: In this validation study, 300 older people were selected by cluster sampling method. Data were collected using a checklist for demographic characteristics, the FS, and the Oxford happiness questionnaire. The validity (face, content, convergent, and construct) and reliability (Cronbach's alpha, test-retest) of the FS was evaluated in this cross-sectional study. RESULTS: The exploratory factor analysis demonstrated a one-dimensional structure consisting of 8 items with an eigenvalue of 3.583. The model had a good fit [χ2 = 52.983, p < 0.001, χ2/df = 2.944, GFI = 0.958, CFI = 0.915, IFI = 0.949, TLI = 0.919, AGFI = 0.948, and RMSEA = 0.081, SRMR = 0.086] with all factor loadings greater than 0.5 and statistically significant. A test of concurrent validity showed a direct and significant association between the FS and the Oxford happiness questionnaire (r = 0.647, p < 0.001). The results of the reliability tests confirmed that the values of Cronbach's alpha coefficient (0.819) and test-retest (0.821) were acceptable. CONCLUSION: The Persian version of the FS demonstrated suitable validity and reliability among a sample of older participants.

Spontaneous direct inguinal hernia rupture and intestinal mesenteric separation: A case report.

Spontaneous evisceration is a rare complication that becomes life-threatening in direct inguinal hernia. A female at the age of 44, weighing 50 kg looked cachectic and was suffering from swelling on the left groin for the last several years. The evisceration of the small intestine as separated from the mesenterium transpired in the subsequent stage of a spontaneous rupture in the left inguinal region after severe coughing. The region ruptured was sealed after small intestine resection carried out through the incision perforated; mesh herniorrhaphy was implemented at the end of the 3rd month. The spontaneous rupture may transpire depending on malnutrition and cachexia not only after the complications by hernia, such as incarceration, strangulation but also after factors increasing intra-abdominal pressure. Elective surgical treatment must be implemented in hernia regardless of its kind. Complications likely to transpire in cases where intervention is conducted too late may threaten the patient's life.
