BackgroundAn association between depression and headache is well established, but the specificity to migraine is unclear.AimsTo investigate the specificity of the association of depression and migraine.MethodPeople with recurrent depression (n=1259) were compared with psychiatrically healthy controls (n=851) to investigate headache defined according to International Headache Society criteria in each group.ResultsAll headache types were more prevalent in the case group than in the controls. However, the strongest association was between depression and migraine with aura (OR=5.6). Among participants with recurrent headaches, migraine with aura (but not other forms of headache) was highly significantly associated with depression.ConclusionsThe data suggest that not only is there a general relationship between headache and depression but also that among people with recurrent headache there is a specific association between depression and migraine with aura. The association is likely to be explained by overlapping aetiological risk factors.

UNSTRUCTURED Objective: To investigate the association of the non-communicable chronic disease (NCD) with the risk of coronavirus disease 2019 (COVID-19). Methods: A case-control study was conducted. The cases were laboratory-confirmed COVID-19 who were treated in the Union Hospital in Wuhan. The healthy controls were randomly selected from the participants of the Hunan Government Employee Cohort study who were not infected with COVID-19, matching by age and sex. NCDs including hypertension, diabetes, coronary heart disease, chronic pulmonary disease, and cancer were determined by self-reportings, use of medications, measurements, and/or laboratory testings. The severity of COVID-19 was determined by physicians according to the guideline. Logistic regression was used to estimate the association, in terms of odds ratio (OR). Results: A total of 468 cases and 1404 controls (1:3) were included in the analysis with a mean age of 59.1±12.8 years and 51.7% male. The case group comprised 134 moderately ill, 275 severely ill, and 59 critically ill COVID-19 patients. Patients with diabetes (OR=3.23, P<0.001), chronic pulmonary disease (OR=5.99, P<0.001), and hypertension (OR=1.45, P=0.001) showed a significantly increased risk of COVID-19 infection compared to the healthy controls. Additionally, diabetes, chronic pulmonary disease, hypertension, and the number of comorbid NCDs were associated with the severity of COVID-19 dose-dependently. Conclusions: Patients with diabetes, hypertension, and chronic pulmonary disease are at a higher risk of having COVID-19 and developing severe type of the disease.

AbstractObjectivesRecently, oxidative stress (OS) has been described extensively as an important cause of men infertility. The nitric oxide synthase 3 (NOS3) gene expression involved in normal spermatogenesis regulation in testis. Several single nucleotide polymorphisms (SNPs) on NOS3 gene are reported in association with sperm function and spermatogenesis impairment in infertile men. In present study, we investigated association of NOS3 gene rs1799983 G/T polymorphism in Iranian Azeri male with idiopathic asthenozoospermia (AZS).MethodsIn this case-control study, we collected 50 males with idiopathic AZS as a case group and 50 age and ethnically matched male as healthy controls from East Azerbaijan area, Iran. The case and control groups genotyping was performed using tetra-primer amplification refractory mutation system-polymerase chain reaction (Tetra-ARMS PCR) method.ResultsGenotype frequency in AZS patients was 40% GG, 60% GT, and 0% TT, whereas in healthy controls were 60% GG, 30% GT, and 10% TT. Statistical analysis showed that the GT heterozygous genotype frequency of NOS3 gene rs1799983 G/T polymorphism in AZS patients was significantly more than healthy controls (p>0.05).ConclusionsWe demonstrated that NOS3 gene rs1799983 G/T polymorphism was associated with AZS in Iranian Azeri men. However, more studies on different geographic areas, races and ethnicities are required to determine exact role of NOS3 gene rs1799983 G/T polymorphism in idiopathic AZS.

Breast cancer (BC) is the most frequently diagnosed cancer among women in the world. Genetic polymorphisms in Interleukin (IL) genes are one of the most important risk factors in BC. The aim of this study was to investigate the association of rs1946518 C/A polymorphism in the promoter region of the IL-18 gene and BC risk in Iranian women. In this case-control study, we recruited 140 women with BC as a case group and 140 age and ethnically matched women as healthy controls from East Azerbaijan, Tabriz in Iran. The genomic DNA was extracted using a salting-out method from peripheral blood leukocytes. Genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The genotype distribution in BC patients was 37.86% CC, 47.14% CA, and 15.00% AA, whereas in healthy controls these were 40.72% CC, 42.85% CA, and 16.43% AA. Statistical analysis showed that the genotype and allele frequencies of IL-18 rs1946518 C/A polymorphism were not significantly different between BC patients and healthy controls (p>0.05). The only significant difference between cases and controls was related to family history (p=0.023). In conclusion, our study indicated that IL-18 rs1946518 C/A polymorphism was not associated with BC in the Iranian women population. However, more studies on different races and geographic areas are required to determine the exact role of rs1946518 C/A polymorphism in prognosis, diagnosis, and risk of BC.

AbstractBackgroundRecurrent pregnancy loss (RPL) referred to two or more consecutive abortions before 20th week of pregnancy. The imbalance of inflammatory factors such as interleukins (IL) can be a significant factor in the RPL. The aim of this study was to investigate association of interleukin-33 (IL-33) gene rs16924159 polymorphism and RPL in Iranian Azeri women.Materials and methodsThis case-control study consisted of 100 women with RPL as case group and 100 healthy controls with successful delivery. Genomic DNA was extracted from whole blood samples using salting out method. The fragments of the rs16924159 polymorphism were amplified by PCR and the genotyping was performed using DNA sequencing.ResultsThe obtained results showed that frequency of GA genotype and G allele of rs16924159 polymorphism in the case group was significantly more than healthy controls (p = 0.033).ConclusionsGenerally, we showed that the IL-33 gene rs16924159 polymorphism may play an important role in risk of RPL in the Iranian Azeri women. However, further studies on different races and geographic areas can be useful in identification of effects of rs16924159 polymorphism on RPL.

Background:Cardiovascular disease (CV) is the most frequent cause of death in rheumatoid arthritis (RA) patients. It is well known that RA acts as an independent cardiovascular risk factor.Objectives:To assess the CV risk in RA patients using carotid ultrasonography (US) additionally to the traditional CV risk factors.Methods:A prospective transversal case control study was performed, including adult RA patients who fulfilled ACR/EULAR 2010 criteria and healthy controls matched according to CV risk factors. Population over 75 years old, patients with established CV disease and/or chronic kidney failure (from III stage) were excluded. The US evaluator was blinded to the case/control condition and evaluated the presence of plaques and the intima-media thickness. Statistical analysis was performed with R (3.6.1 version) and included a multivariate variance analysis (MANOVA) and a negative binomial regression adjusted by confounding factors (age, sex and CV risk factors).Results:A total of 200 cases and 111 healthy controls were included in the study. Demographical, clinical and US data are exposed in table 1. Not any difference was detected in terms of CV risk factors between the cases and controls. In both groups a relationship between age, BMI and high blood pressure was detected (p<0.001).Table 1.Table 2.RA basal characteristicsDisease duration (years)16,98 (11,38)Erosions (X-Ray of hands/feet)163 (81,5%)Seropositive (RF/anti-CCP)146 (73%)Extra-articular symptoms44 (22%)Intersticial difusse lung disease10 (5%)Rheumatoid nodules14 (7%)Prednisone use103 (51,5%)Median dose of Prednisone last year (mg)2,34 (2,84)sDMARDsMethotrexate104 (52%)Leflunomide29 (14,5%)Hydroxycloroquine9 (4,5%)bDMARDs89 (44,5%) TNFi41 (20,5%) Abatacept15 (7,5%) IL6i22 (11%) RTX11 (5,5%)JAKi26 (13%) Baricitinib11 (5,5%) Tofacitinib15 (7,5%)DAS 28-ESR3,1 (2,3, 3,9)SDAI7,85 (4,04, 13,41)HAQ0,88 (0,22, 1,5)RF (U/mL)51 (15, 164,25)Anti-CCP (U/mL)173 (22, 340)Patients showed higher intima-media (both right and left) thickness compared to controls (p<0.006). Moreover it was also related to the disease duration and DAS28 score (p<0.001). A higher plaque account was noted in cases(p<0.004) and it was also related to the disease duration (p<0.001).Conclusion:RA implies a higher CV risk. Traditional CV risk factors explains only partially the global risk. These findings support that RA acts as an independent cardiovascular risk factor.Disclosure of Interests:None declared

<b><i>Aim:</i></b> The aim of this study is to examine possible associations between the transfusion of RBC or platelets (PLTs) and the development of retinopathy of prematurity (ROP) in infants. <b><i>Methods:</i></b> This retrospective, national, case-control study included all live births in Switzerland between 2013 and 2018. We investigated preterm infants at a gestational age of &#x3c;28 weeks, who developed higher stage ROP (≥stage 2, <i>n</i> = 178). Each case infant was matched to another of the same sex who did not develop ROP (<i>n</i> = 178, control group). <b><i>Results:</i></b> When compared with the control group, we observed higher numbers of RBC transfusions per infant and higher percentages of infants receiving PLT transfusions in the case group. An adjusted logistic regression analysis revealed that both RBC (odds ratio [OR] 1.081, 95% confidence interval [CI] 1.020–1.146) and PLT transfusions (OR = 2.502, 95% CI 1.566–3.998) numbers were associated with ROP development. <b><i>Conclusions:</i></b> Multiple RBC and PLT transfusions are associated with higher stage ROP development. Prospective studies are required to determine their potential as risk factors.

Citrullinated proteins have been suggested to play a critical role in the pathogenesis of multiple sclerosis (MS). Anticyclic citrullinated peptide (anti-CCP) antibody is used in the early diagnosis of rheumatoid arthritis (RA). The objective of this study was to investigate the presence of anti-CCP antibody in patients with MS compared to RA patients and healthy controls. Fifty patients with MS (38 females, 12 males; mean age 36.72 ± 8.82 years), 52 patients with RA (40 females, 12 males; mean age 40.87 ± 10.17 years), and 50 healthy controls (32 females, 18 males; mean age 38.22 ± 11.59 years) were included in this study. The levels of serum anti-CCP antibody were measured using an enzyme-linked immunosorbent assay (ELISA). The results of the study showed that anti-CCP antibody levels were significantly higher in RA patients versus MS or healthy controls(P<0.001). Moreover, anti-CCP antibody was positive in 43 (83%) patients with RA, while it was negative in all MS patients as well as in all healthy controls. Also, no significant correlation was found between the anti-CCP levels and EDSS scores(r=-0.250). In conclusion, the results of this study did not support a positive association between serum anti-CCP antibody and MS.

Abstract Background In March 2020, the US Food and Drug Administration decided that the dangers related to neuropsychiatric events (NPEs) of montelukast, one of the leukotriene modifying agents (LTMAs), should be communicated through ‘boxed warning’. In case of NPEs, the prevalence has been the highest in elderly people. Because the characteristics of the elderly such as old age itself can act as risk factors. Therefore, an investigation on safety of LTMAs related to NPEs in elderly using LTMAs is needed. Method A nested case-control study using an elderly sample cohort from the Korean National Health Insurance Service database was used. The asthma cohort included asthma patients newly diagnosed between 2003 and 2013. Within the asthma cohort, the case group was defined as patients who were diagnosed with NPEs. Among patients who had never been diagnosed with NPEs, the control group was selected by matching 1:1 by propensity score. Patients who were prescribed LTMAs for 1 year prior to index date were defined as the exposure group. The logistic regression model was used to measure the effect of LTMAs on NPEs. Results We identified 141,165 patients with newly diagnosed asthma, and selected 31,992 patients per each case and control group. Exposure to LTMAs significantly increased the risk of overall NPEs about in comparison with the absence of exposure (crude odds ratio [OR] 1.58, 95% CI 1.50–1.68). After adjusting for confounding factors, the overall NPEs risk increased (adjusted OR, 1.67, 95% CI 1.58–1.78). Conclusion This study suggests that elderly asthma patients prescribed LTMAs had a higher risk of NPEs than patients who were not treated with LTMAs. Therefore, clinicians should be aware of the potential risks of LTMAs.

Asfiksia perinatal merujuk pada kekurangan oksigen selama persalinan, sehingga berpotensi menyebabkan kematian dan kecacatan. WHO memperkirakan  4 juta anak terlahir dengan asfiksia setiap tahun, dimana 1 juta di antaranya meninggal dan 1 juta anak bertahan hidup dengan gejala sisa neurologis yang parah. Penelitian ini bertujuan untuk menganalisis faktor risiko fetal dan tali pusat pada asfiksia neonatal.Penelitian dilakukan di lakukan di RS Dr Moewardi Surakarta dengan pendekatan  quantitative retrospective case control study. Data diambil dari rekam medis antara  tahun 2013-2018. Penelitan ini melibatkan  264 neonatal yang terdiri dari 88 kelompok kasus dan 176  kelompok control. Kelompok kasus adalah bayi dengan diagnosa  asfiksia yang  dilakukan analisis terhadap faktor risiko fetal, sedangkan bayi yang tidak mengalami asfiksia dijadikan  kelompok kontrol. Hasil analisis statistik uji Chi-Square dan Fisher Exact ditemukan bahwa  kelahiran prematur (OR 2,07 CI 95% P 0,02), persalinan dengan tindakan (OR 3,61 CI 95% P 0,00), berat bayi (OR 2,85 CI 95% P 0,00), posisi janin (OR 2,37 CI 95% P 0,05), tali pusat ( QR 3,071 CI 95%  P 0,01)  berisiko terhadap insiden asfiksia perinatal. Air ketuban yang bercampur meconium (OR 1,51 CI 95% P 0,16) tidak memiliki risiko  dengan Asfiksia perinatal. Kesimpulan: Risiko terhadap insiden asfiksia perinatal  meliputi kelahiran prematur, persalinan dengan tindakan, berat bayi, posisi janin,  dan tali pusat.Perinatal asphyxia refers to a lack of oxygen during labor, which has the potential to cause death and disability. WHO estimates  4 million children born with asphyxia each year, in  which 1 million dies and 1 million survive with severe neurological sequelae. This study aims to analyze fetal and umbilical risk factors in neonatal asphyxia.This research is a quantitative retrospective case-control study, which was conducted at The Dr. Moewardi  hospital,  Surakarta. Data was taken from  medical records from 2013-2018. The case group was patients diagnosed  asphyxia, while those who did not experience asphyxia were treated as a control group.  A total of 264  samples, consisting of 88 case group respondents and 176 control group respondents. Statistical analysis Chi- Square and Fisher Exact found that preterm birth (OR 2.07 CI 95% P 0.02), labor with instrument or complication (OR 3.61 CI 95% P 0.00), infant weight (OR 2.85 CI 95% P 0, 00), fetal position (OR 2.37 CI 95% P 0.05), umbilical cord (QR 3.071 CI 95% P 0.01) are at risk for the incidence of perinatal Asphyxia. The amniotic fluid mixed with meconium (OR 1.51 CI 95% P 0.16) has no risk with perinatal asphyxia.The risk factors of incidences of perinatal asphyxia were  preterm birth, labor with instrument or complication, baby weight, fetal position and umbilical cord.
