Abstract
BACKGROUND . Low back pain is one of the major causes of morbidity worldwide. Studies on low back pain quality of care are limited. This study aimed to evaluate the quality of care of low back pain worldwide and compare gender, age, and socioeconomic groups. METHODS . This study used GBD data from 1990 to 2017 from the Institute for Health Metrics and Evaluation (IHME) website. Extracted data included low back pain incidence, prevalence, disability-adjusted life years (DALYs), and years lived with disability (YLDs). DALYs to prevalence ratio and prevalence to incidence ratio were calculated and used in the principal component analysis (PCA) to make a proxy of the quality-of-care index (QCI). Age groups, genders, and countries with different socioeconomic statuses regarding low back pain care quality from 1990 to 2017 were compared. RESULTS The proxy of QCI showed a slight decrease from 36.44 in 1990 to 35.20 in 2017. High- and upper-middle-income countries showed a decrease in the quality of care from 43.17 to 41.57 and from 36.37 to 36.00, respectively, from 1990 to 2017. On the other hand, low and low-middle-income countries improved, from a proxy of QCI of 20.99 to 27.89 and 27.74 to 29.36, respectively. CONCLUSION . Despite improvements in the quality of care for low back pain in low and lower-middle-income countries between 1990 and 2017, there is still a large gap between these countries and higher-income countries. Continued steps must be taken to reduce healthcare barriers in these countries.

Abstract
Introduction The clinical course of LBP is complex and chronicity is more frequent than once thought. Moreover, insufficient evidence was found in support of any specific approach at the level of the general population. Research question This study aimed to evaluate the effectiveness of providing a back care package through the primary healthcare system in decreasing the rate of CLBP in the community. Material and methods Clusters were primary healthcare units with the covered population as participants. The intervention package comprised both exercise and educational content in the form of booklets. Data regarding LBP were collected at baseline, 3 and 9-month follow-ups. The LBP prevalence and the incidence of CLBP in the intervention group compared to the control group were analyzed using logistic regression through GEE. Results Eleven clusters were randomized including 3521 enrolled subjects. At 9 months, the intervention group showed a statistically significant decrease in both the prevalence and the incidence of CLBP, compared to the control group (OR = 0.44; 95% CI = 0.30-0.65; P < 0.001 and OR = 0.48; 95% CI = 0.31-0.74; P < 0.001, respectively). Discussion and conclusion The population-based intervention was effective in reducing the LBP prevalence and CLBP incidence. Our results suggest that preventing CLBP through a primary healthcare package including exercise and educational content is achievable.

Abstract
PURPOSE OF THE STUDY PCR is the current standard test for the diagnosis of SARS-CoV-2 infection. However, due to its limitations, serological testing is considered an alternative method for detecting SARS-CoV-2 exposure. In this study, we measured the level of SARS-CoV-2 IgM and IgG antibodies of male professional football players and compared the results with the standard PCR test to investigate the association between the two tests. STUDY DESIGN Participants were male professional football players and team officials. Nasopharyngeal swabs and peripheral blood samples were collected for the PCR and serological tests, respectively. Also, previous records of COVID-19 testing and symptoms were gathered. Those with previous positive PCR tests who tested negative for the second time were considered to be recovered patients. RESULTS Of the 1243 subjects, 222 (17.9%) were seropositive, while 29 (2.3%) tested positive for the SARS-CoV-2 PCR test. Sixty percent of symptomatic cases with a negative PCR were found to be seropositive. The mean level of IgM was significantly higher in PCR-positive and symptomatic subjects, whereas the recovered cases showed significantly higher levels of IgG. CONCLUSION Our study revealed an inconsistency of results between the two tests; therefore, although application of serological assays alone seems insufficient in diagnosing COVID-19 disease, the findings are beneficial in the comprehension and the management of the disease.

Abstract
Due to concerns of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) transmission, professional football (soccer) was terminated almost everywhere in the world in early 2020. These are the results from a prospective cohort study conducted in Iran to analyze the resumption of professional football during the coronavirus disease 2019 (COVID-19) pandemic under assigned protocols and regulations. Sixteen teams consisting of 805 individuals formally agreed to follow the rules assigned by the ministry of health and CORONA headquarters in sport, and were subject to study monitoring. The resumption process was implemented over a 5-month period, beginning with a training phase followed by 14 match weeks of professional football. A self-declaration form was provided for the subjects to report any suspicious symptoms immediately and serial PCR testing was performed every 10 days using nasal swab samples. Those with positive tests were to be isolated until the symptoms were resolved or a negative test was returned. Of the 805 individuals included, 17.89% subjects were infected by the SARS-CoV‑2 virus (85 players and 59 staff members and officials). Only two matches were canceled in accordance with the regulations, and no severe cases were found. Case-tracing suggested that most transmissions occurred off the pitch. In conclusion, applying strict hygiene protocols and early case identification by performing repetitive PCR testing could benefit the resumption of professional football competitions.

Abstract
Purpose
Breast cancer is one of the most prevalent malignancies worldwide. This study aimed to compare the level of knowledge and attitude of females regarding Breast cancer and to determine the role of knowledge, attitude and barriers in performing regular self-examination.
Design/methodology/approach
Non-physician females aged 18 years old or above were enrolled in this cross-sectional study in two groups of usual clients and healthcare staff from January 2018 to January 2019 from a healthcare center in Sari, a major city in the northern district of Iran. A questionnaire was used to score the participants’ knowledge and attitude levels using questions about the participants' knowledge and attitude towards Breast cancer along with their status on Breast self-examination and barriers. Mean scores were used for statistical analysis using SPSS V25. p < 0.05 was considered significant.
Findings
A final dataset of 279 females were collected. A significant difference in the knowledge and attitude regarding breast cancer was found between the two study groups (p < 0.001). The practice of BSE was significantly lower in the usual clients compared to non-physician healthcare staff (p < 0.001). The most frequent barriers for not performing a regular BSE were fear of finding a mass in usual clients (17.8%) and lack of confidence in healthcare staff (3.8%).
Research limitations/implications
Limitations include single-centered sample selection.
Practical implications
Given the importance of early detection in breast cancer prevention and the general taboo regarding breast cancer screening methods in certain parts of the world, leading to poor results in early detection and prevention, the authors believe that it is of superior importance to address and promote positive attitudes in general population towards breast self-examination.
Originality/value
Given the importance of early detection in breast cancer prevention, and the general taboo regarding breast cancer screening methods in certain parts of the world, leading to poor results in early detection and prevention, the authors believe that it is of superior importance to address and promote positive attitudes in general population toward breast self-examination. The authors of this study believe that the manuscript represents honest and original work.

Abstract
Introduction: Melanocytoma is a rare benign stationary tumor that usually appears as a pigmented lesion on the optic disk. Optic Disc Melanocytoma (ODM) can compress the optic nerve or undergo necrosis, leading to ischemic axonal loss and visual field defect, similar to those caused by glaucoma. Also, ODM often displays a clinical diagnostic dilemma due to its similarities with melanoma. Some patients have undergone enucleation because of uncertainty between both pathologies. Progressive growth and malignant transformation can be documented by close monitoring of the patient’s eyes. Fundus examination and ancillary imaging procedures such as fundus photo, autofluorescence, B-scan ultrasonography, fluorescein angiography, and spectral-domain optic coherence tomography are powerful tools for ODM diagnosis and management. Case Presentation: A 19-year-old female presented with a decrease in vision in the left eye for about 3 months. Her visual acuity was 20/20 and 20/80 in her right and left eyes, respectively. Funduscopic examination of the left eye showed a well-defined deeply pigmented brownish-black, dome-shaped nodular mass covered the entire optic disc with the normal-appearing overlying vitreous, macula, and surrounding retina. Short-wave autofluorescence revealed hypo-autofluorescence on the pigmented mass lesion. The patient’s condition did not change significantly over 2 years of follow-up. The diagnosis was made as ODM. Conclusions: Melanocytomas grow very slowly over several years or remains stable, in contrast to malignant melanoma. Although ODM tends to have benign behavior, it may adversely affect visual function. Yearly fundus examination is necessary for monitoring growth and detecting malignant transformation. Visual loss can result from optic neuropathy or retinal vascular obstruction. In suspicious cases, close follow-up with serial fundus photographs is essential, even though the malignant transformation is exceptional.

Abstract
Abstract
Background
Overproduction of reactive oxygen species as a result of hyperglycemia in diabetes mellitus leads to microvascular complications. Glutathione S-transferases play important detoxifying roles with antioxidant potentials. This study aimed to assess whether the glutathione S-transferase M1 and T1 genotypes were associated with type 2 diabetes mellitus microangiopathic complications in the Iranian population.
Results
In this case-control study, the frequencies of null GSTM1 and GSTT1 genotypes were 4/72 (5.56%) and 12/72 (16.67%) respectively, in uncomplicated DM group. The frequencies of null GSTM1 and GSTT1 genotype in complicated DM group were 16/134 (11.94%) and 37/134 (27.61%), respectively. The proportion of GSTM1 null genotypes was higher in diabetic nephropathy compared to non-nephropathy (19.3% vs. 6.04 %, P = 0.006). At GSTT1 locus, patients with diabetic peripheral neuropathy had a higher frequency of deletion compared to those of without neuropathy (30.39% vs. 23.49%) (P = 0.02).
Conclusion
Selective polymorphisms encoding GSTM1 and GSTT1genes may prove useful as genetic markers to recognize individuals with an increased trend in developing diabetic nephropathy and neuropathy, respectively. This will help better identify individuals at higher risk toward microvascular complications of type 2 diabetes due to genetic susceptibility.

Abstract
BACKGROUND Postoperative Nausea and Vomiting (PONV) is a multifactorial surgical complication with an unclear underlying cause. Anesthetic methods, patients' characteristics and the type of surgery are considered as factors affecting PONV. This study was designed to compare the effect of inhalational and intravenous anesthesia in abdominal surgery on the incidence and severity of PONV. METHODS A single-blinded prospective randomized clinical trial on 105 patients aged 18-65 years was carried out. Patients were divided in two groups of Total Intravenous Anesthesia (TIVA) and Inhalational anesthesia. The incidence and severity of PONV were examined at 0, 2, 6, 12, and 24hours after the surgery. The use of a rescue antiemetic was also evaluated. RESULTS Fifty point nine percent of the patients in the inhalation group and 17.3% of the patients in the intravenous group developed PONV (p <0.001). The incidence of vomiting was reported in 11.3% of the Inhalational group and 3.8% of the TIVA group (p=0.15), and 24.5% of patients in the Inhalation group and 9.6% of patients in the intravenous group needed an antiemetic medication (p=0.043). CONCLUSION The incidence of postoperative nausea and vomiting and the need for administration of an antiemetic rescue drug, and the severity of nausea in patients were significantly lower in the TIVA group.

Abstract
Background: Short-term memory disorder following surgery and anesthesia is a common complication of anesthesia and a common complaint of the patients. Aims: This study was designed to assess memory impairment in patients undergoing elective surgery, investigate the effect of general anesthesia (GA) on memory, and identify the factors contributing to it, as well as the specific effect of anesthesia on each of the memory domains. Setting and Design: This cross-sectional study was performed in a university hospital. Methods and Materials: Patients with the American Society of Anesthesiologists (ASA) Class I, II, and III who were candidates for elective abdominal surgery were enrolled. Patients answered several questions based on the Wechsler Memory Scale–Revised V (WMS-R-V), a standardized questionnaire, minutes before entering the operating room (OR) and again after 24 h postoperation, and the differences were recorded. Statistical Analysis: Analysis was performed using T-independent and Chi-square tests with Pearson's coefficient and Fischer's exact test and Man–Whitney test. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software. Results: Four hundred patients (198 females and 202 males) with a mean age of 50.75 years were enrolled in our study. Our study results showed that short-term memory after GA was significantly decreased compared with preanesthesia (P < 0.05). There was no significant relationship between memory disorder following GA and gender (P = 0.18) or comorbidities (P = 0.138). However, older age was found to be a contributing factor to memory loss following GA (P < 0.001). The highest and lowest effect of GA were found on the number repeat (45.2%) and personal information (16.2%) domain of the memory. Conclusion: GA significantly reduces the patient's short-term memory after the surgery.

Abstract
The experience of pre-operative anxiety in patients is a common and accepted issue; however, anxiety can potentially increase the patients' need for care, the level of post-operative pain, and ultimately patients' morbidity and mortality. The goal of this study was to determine the patients' pre-operative anxiety level right before they undergo surgery in the operating room. This study was conducted as a prospective crosssectional study. Accordingly, completed State-Trait Anxiety Inventory questionnaires as well as demographic and contextual variables of 230 patients undergoing surgery were evaluated. Data analysis was taken out using SPSS v24. P of less than 0.05 was considered significant. 230 patients with an average age of 48.95 (14.68) years were enrolled. The frequency of mild, moderate, and severe anxiety among the patients was 50.8%, 37%, and 12.2%, respectively. The analysis revealed that the patients' age, gender, occupation, awareness about the type of anesthesia, and place of residence, as well as the type of anesthesia, had no significant correlation with the patients' pre-operative anxiety. However, a significant difference was found regarding patients’ preoperative anxiety level and their educational, marital, awareness of post-operative complications, and trait anxiety status as well as their history of anesthesia. Therefore, to reduce post-operative complications, it is recommended that the patients with these characteristics be given priority for interventions aimed at reducing pre-operative anxiety.

Abstract
Aim (AC)n promoter region of the aldose reductase (ALR) genes polymorphism has been associated with diabetic microvascular complications (MVCs). The aim of this study was to find the relationship between dinucleotide repeat (AC)n polymorphisms of the ALR gene and the occurrence of MVCs, such as diabetic retinopathy, neuropathy, and nephropathy in Iranian type 2 diabetic (T2D) patients. Methods This prospective case-control study was performed on T2D patients who were categorized into two groups based on the presence or absence of diabetic microangiopathy. All patients were provided informed consent. After extracting genomic DNA, the (AC)n of the ALR gene was determined using Polymerase chain reaction (PCR). Results Thirteen alleles of the (AC)n gene polymorphism were detected including Z + 16, Z + 14, Z + 8, Z + 6, Z + 4, Z + 2, Z, Z - 2, Z - 4, Z - 6, Z - 8, Z - 10, and Z - 12. The frequency of the Z - 4 allele was significantly higher in patients with retinopathy, nephropathy, and autonomic neuropathy compared with those with long-term uncomplicated diabetes (P < 0.001, P < 0.001, P = 0.031, respectively). After controlling for baseline risk factors, we found that the carrier of the Z - 4 allele of ALR (AC)n polymorphism had a higher risk of diabetic retinopathy and diabetic nephropathy (P < 0.001). The homozygosity for the Z - 4 allele was found to be associated with diabetic microangiopathy. Conclusion Our results showed that ALR (AC)n gene polymorphism in Iranian patients with type 2 diabetes independently, predispose retinal, renal and neural microvascular to diabetic complications.

Abstract
Human melanoma cells (from biopsies and culture) express sialyl-Lewis(x) and sialyl Lewis(a), the ligands for ECAM. These ligands may facilitate tumor progression and metastasis in human cancers. To test whether the antibodies to these ligands inhibit tumor progression, IgG and IgM responses to sLe(x) and sLe(a) were induced in C57BL/6j mice (n = 76) by immunization with human melanoma cells, with or without adjuvants (BCG, MPL, KLH). Control mice were treated with saline or BCG. Tumor growth and antigen expression were monitored after challenge with B16 mouse melanoma cells expressing sLe(x), sLe(a) and the ganglioside GM3. Tumor growth was reduced in mice immunized with BCG alone or cells with BCG or MPL, while tumors in mice receiving cells without adjuvants grew larger than in the control. Augmentation of IgM titers to sLe(x) and GM3 after immunization with BCG, or with cells with BCG or MPL correlated with retarded tumor growth, while increased IgG titers to sLe(x) significantly correlated with aggressive tumor growth in mice immunized with cells without adjuvants. SLe(x), sLe(a) and GM3 were expressed in tumors from mice treated with saline or BCG. SLe(x) expression, in particular, was lost in tumors growing in mice immunized with cells with or without adjuvants. Anti-sLe(x) antibodies may promote or prevent tumor growth by antigenic modulation or by cytotoxic killing of tumor cells. Since early anti-sLe(x) IgM correlated with tumor regression, in contrast to anti-sLe(x) IgG, it may serve as a potential early endpoint for the effectiveness of melanoma vaccines expressing the antigens.

Abstract
BACKGROUND Sialyl Lewis(x) (sLe(x)) and sialyl Lewis(a) (sLe(a)), the endothelial-selectin ligands involved in extravasation of neutrophils and carcinomas, have been identified in human melanoma. This study explored the following issue: If these ligands are immunogenic tumor-differentiation antigens, they would be potential targets for immunotherapy because of their putative roles in extravasation and metastasis. METHODS Using a cell-suspension enzyme-linked immunosorbent assay (ELISA), the expression of sLe(x) and sLe(a) on the surface of normal melanocytes, melanoma cells from biopsies, and cell lines (M10-v, M24, and M101) constituting melanoma cell vaccine (MCV) were quantitated. Melanoma patients were immunized with the MCV expressing these antigens. Sera of normal individuals, sera of patients, and sera that adsorbed to sLe(x) and sLe(a) were titrated for anti-sLe antibodies by ELISA to verify the immunogenicity of the ligands. RESULTS The normal melanocytes did not express sLe(x) and poorly expressed sLe(a). Melanoma cells from tumor biopsies and MCV lines expressed both sLe(x) and sLe(a). Sialyl Le(x) was associated with glycoprotein(s) in M10-v, and sLe(a) occurred as a glycolipid moiety in M24. MCV recipients developed high titers for immunoglobulin (Ig)M but not IgG to both ligands. IgM titers to these ligands were low in normal subjects. In some of the preimmune sera of patients, the titers were threefold above normal. Six of 13 MCV recipients developed at least a twofold increase in anti-sLe titers above preimmune level after the second or third immunization. Adsorption studies suggested that both ligands were immunogenic. CONCLUSIONS The melanoma-associated sLe(x) and sLe(a) are immunogenic neoplasm-differentiation antigens and are therefore potential targets for passive and active specific immunotherapy in the treatment of melanoma.

Abstract
Allogenic whole cell and lysate cancer vaccines are associated with very different clinical outcome, which could be due to different immune responses to critical tumor-associated antigens. We used a guinea pig model to evaluate the immune responses to melanoma-associated carbohydrate antigens administered in whole cell and soluble lysate vaccines produced from the same cell lines and administered with or without Bacille Calmette-Guerin (BCG). Animals immunized with whole cell vaccine developed a significantly higher delayed-type hypersensitivity (DTH) reaction. The IgG response to all tumor-associated carbohydrate antigens except GD2 was significantly higher in animals immunized with whole cell vaccine than lysate vaccine. This study indicates that whole cell vaccine is superior to soluble or lysate vaccine because it induces a better immune response against cell-surface antigens. The addition of BCG significantly increased the antibody response, suggesting that an exogenous adjuvant may immunopotentiate antigens better in the presence of an intact cell membrane.
