Chronic stress is closely linked to the metabolic syndrome, diabetes, hyperuricemia and thromboembolism, but the mechanisms remain elusive. We reported recently that stress targets visceral adipose tissue (VAT), inducing lipolysis, low-grade inflammation with production of inflammatory adipokines, metabolic derangements such as insulin resistance, and prothrombotic state. In the present study, we hypothesized the involvement of VAT xanthine oxidoreductase (XOR), a source of reactive oxygen species (ROS) and uric acid (UA) in the above processes. Restraint stress in mice resulted in upregulation of XOR and xanthine oxidase activity, accumulation of ROS in VAT as well as liver and intestine, increase in serum UA levels, upregulation of NADPH oxidase subunits and downregulation of antioxidant enzymes. Immunohistochemistry and RT-PCR analysis also showed that restraint stress induced VAT monocyte accumulation and proinflammatory adipokine production, resulting in reduced insulin sensitivity and induction of plasminogen activator inhibitor-1 and tissue factor in VAT. Treatment with febuxostat, a potent XO inhibitor, suppressed stress-induced ROS production and VAT inflammation, resulting in improvement of serum UA levels, insulin sensitivity, and prothrombotic tendency. Our results suggest that stress perturbs glucose and UA metabolism, and promotes prothrombotic status, and that XO inhibition by febuxostat might be a potential therapy for stress-related disorders.

Background Coronavirus disease 2019 (COVID-19) is a new viral disease that has caused a pandemic in the world. Due to the lack of vaccines and definitive treatment, preventive behaviors are the only way to overcome the disease. Therefore, the present study aimed to determine the preventive behaviors from the disease based on constructs of the health belief model. Methods In the present cross-sectional study during March 11–16, 2020, 750 individuals in Golestan Province of Iran were included in the study using the convenience sampling and they completed the questionnaires through cyberspace. Factor scores were calculated using the confirmatory factor analysis. The effects of different factors were separately investigated using the univariate analyses, including students sample t -test, ANOVA, and simple linear regression. Finally, the effective factors were examined by the multiple regression analysis at a significant level of 0.05 and through Mplus 7 and SPSS 16. Results The participants’ mean age was 33.9 ± 9.45 years; and 57.1% of them had associate and bachelor's degrees. Multiple regression indicated that the mean score of preventive behavior from COVID-19 was higher in females than males, and greater in urban dwellers than rural dwellers. Furthermore, one unit increase in the standard deviation of factor scores of self-efficacy and perceived benefits increased the scores of preventive behavior from COVID-19 by 0.22 and 0.17 units respectively. On the contrary, one unit increase in the standard deviation of factor score of perceived barriers and fatalistic beliefs decreased the scores of the preventive behavior from COVID-19 by 0.36 and 0.19 units respectively. Conclusions Results of the present study indicated that female gender, perceived barriers, perceived self-efficacy, fatalistic beliefs, perceived interests, and living in city had the greatest preventive behaviors from COVID-19 respectively. Preventive interventions were necessary among males and villagers.

There is a relationship between mental and physical health. Depression and anxiety are linked with the development of several chronic diseases. The purpose of the present study was to determine the prevalence and factors associated with anxiety and depression among adult hypertensive outpatients in Afghanistan. Methods. Two hundred thirty-four consecutive hypertensive patients from December 2015 to August 2016 were recruited to complete the Hospital Anxiety and Depression Scale (HADS) questionnaire, which has scores for classifying the participants having anxiety and depression symptoms. Results. Of the total 234 patients, 81 (34.6%) were males and 153 (65.4%) were females. The mean age was 54.6 ± 12.7 for the hypertensive patients with anxiety and 63.8 ± 15.0 for the hypertensive patients with depression while this figure was 49.5 ± 10.2 for the adult participants in general population in Kabul city (Saeed, 2013). The prevalence of anxiety and depression (42.3% vs. 58.1%) among hypertensive persons is compared with the same mental disorders among Afghan refugees (39.3% vs. 22.1%) in Dalakee Refugee Camp (in Iran) (Hosseini Divkolaye and Burkle, 2017). Of the total participants, 99 had anxiety (42.3%), 136 had depression (58.1%), and 66 had (28.2%) comorbid anxiety-depression. Multivariate analysis was used. For anxiety age, female gender, smoking, diabetes mellitus, and 2 or more chronic diseases had a significant association. For depression, age and diabetes mellitus had a significant association, and for comorbid anxiety, depression, age, diabetes mellitus, and 2 or more chronic diseases had a significant association. Conclusion. This study shows that anxiety and depression are highly prevalent among hypertensive patients in an outpatient clinic in Afghanistan. There was an association between some sociodemographic and clinical characteristics and anxiety and depression. More studies are needed on a national level to inform the development of strategies for the prevention and control of psychological distress among patients with chronic diseases in Afghanistan.

Background Crystal (methamphetamine) is a strong stimulant of addictive substances that affects the central nervous system. The consumption of this substance is increasing among teenagers and adult young people in the country. In this matter, one of the practical and important ways to its control is to identify the factors leading to its first use. Thus this paper, explores the factors related to the first crystal use in Golestan province, Iran. Methods In a qualitative study, 19 crystal users were recruited in the study conducted in Golestan province by snowball sampling from DIC (Drop-In Center) in addiction treatment centers. The interviews were mostly carried out individually with the participants; only one interview was conducted in an addiction treatment camp in the form of a group-focused discussion. Data analysis was implemented through content analysis in MAXQDA 10 software. Results The mean age of the participants was 35.05 ± 6.06 years with a range of 23–46 years. Meanwhile, the mean of crystal use period was 7.42 (SD: 3.61) and a range of 1–14 years. Based on the obtained data, the reasons for first crystal use could be categorized in six; 1: “crystal use to other drugs rehabilitation”; 2: “Lack of awareness of the addictive nature of crystal”; 3: “stimulating curiosity in public with crystal-use friends”, 4: affordable and convenient use”, 5: “anti-sleeping effects and increasing work efficiency”, and 6: “therapeutic and other misconceptions”“. Conclusions The results indicated that crystal is mostly abused to opium rehabilitation. The lack of awareness and misconceptions about this substance can lead people to crystal use. Therefore, designing public health interventions to increase awareness about negative consequences of crystal use is fundamental to prevent people from abusing it. We suggest designing public health program to promote awareness about health risks of crystal and modifying related misconceptions. Finally, the government can establish policies to mandate sale tax for crystal producers and reduce easy access to crystal especially among youth.

Fissured tongue is a common manifestation of the tongue, marked by the presence of multiple prominent grooves or fissures on the dorsal surface of the tongue. However, there is a lack of studies focusing on the prevalence and factors associated with fissured tongue among patients attending an outpatient clinic in Afghanistan. The purpose of the current study was to determine the prevalence and factors associated with fissured tongue and its effects on the general health of adult outpatients in Afghanistan. The cross-sectional survey was conducted among outpatient populations in Andkhoy City, Afghanistan, between September 2019 and December 2019. A convenience technique was applied by including 1182 patient aged 18-80 years. Socio-economic status, smoking, nass use (smokeless tobacco use) and medical data were collected using face-to-face interviews. We used logistic regression analysis to identify factors associated with fissured tongue. A convenience technique was applied by including patient aged 18-80 years. The studied population consisted of 1182 participants, of whom 573 (48.5%) were males and 609 (51.5%) females. The prevalence of fissured tongue was 27.2% (95% CI: 24.7-29.9%) with males having significantly higher prevalence than females (47.5%, 95% CI: 43.3-51.6% versus 8.2%, 95% CI: 6.2-10.7%, p<0.001). Male participants (OR=7.1, 95% CI: 4.8-10.3), diabetes mellitus (OR=1.6, 95% CI: 1.1-2.3) and smokeless tobacco use (OR=12.0, 95% CI: 8.1-17.6) were the only variables independently associated with fissured tongue. This study suggested that there was a high rate of fissured tongue among an outpatient clinic in Andkhoy, Afghanistan. Male gender, diabetes mellitus, and nass consumption were associated with fissured tongue. Therefore, these factors might usefully be targeted in local health promotion, prevention and early intervention programs.

Tobacco use is one of the main risk factors for a number of chronic diseases, including cancer, lung diseases, and cardiovascular diseases. Nass is a form of smokeless tobacco. It is used most commonly in Central Asia, Afghanistan, Pakistan, and Iran, and is significantly associated with oral and oesophageal cancers. The aim of this study was to determine the prevalence of nass use and its associated factors among patients attending an outpatient clinic in Afghanistan. This cross-sectional study was performed in an outpatient clinic in Andkhoy, Afghanistan, from April to July 2017. The study included 387 consecutive patients. The data collection tool was a questionnaire, which includes three main items: demographic, physical, and biomedical measurements. We performed binary logistic regression to identify independent risk factors of nass use. The study included 387 participants, of whom 225 were males (58.1%) and 162 were females (41.9%). The overall prevalence of nass use was 48.8% (95% CI: 43.8-53.9%), with the Turkmen ethnic group having significantly higher prevalence than other ethnic groups (58.2%, 95% CI: 50.8-65.3% vs 41.8%, 95% CI: 34.7-49.2%). The mean and standard deviation of the age was 63.9 (17.2) years for nass users and 42.3 (17.4) years for non-users.Based on a multivariate analysis, family history of nass use (OR=31.4, 95% CI: 12.5-78.5), illiteracy (OR=8.9, 95% CI: 2.5-31.2), rural residence (OR=2.0, 95% CI: 1.0-3.9), and unemployment (OR=5.4, 95% CI: 1.4-21.4) were associated with nass use. Our results indicate that about half of the participants were nass users, and nass use associated factors were family history of nass use, illiteracy, unemployment, and rural residency in outpatient clinics in Afghanistan. More surveillance data are needed on a national level to inform the development of strategies for the prevention and control of nass consumption in Afghanistan.

Dyslipidemia is known as an independent risk factor for cardiovascular disease. Recently, interest has been raised on the risk of new onset of diabetes mellitus with statin treatment. We report on a 41-year-old man with dyslipidemia. His blood tests at the time of admission showed that there was a rise in low-density lipoprotein levels (155 mg/dl), low high-density lipoprotein levels (34 mg/dl), normal triglyceride levels (82 mg/dl), normal fasting blood sugar levels (85 mg/dl), and normal glycated hemoglobin (HbA1c) (5.3%). Follow-up for about 2.5 years for statin use revealed that the patient’s lipid profile has improved; however, his HbA1c increased from 5.3 to 6.1%. The patient was prescribed Metformin and the statin was replaced with Ezetimibe. Little changes in blood HbA1c levels were observed at 1-year follow-up. Then, dipeptidyl peptidase-4 inhibitors, Sitagliptin, was introduced at 25 mg once per day, and Metformin was discontinued. One year later, the patient’s laboratory tests showed: low-density lipoprotein (77 mg/dl), high-density lipoprotein (33 mg/dl), triglycerides (108 mg/dl), and HbA1c (5.5%). This finding revealed that the dipeptidyl peptidase-4 inhibitor, Sitagliptin is more likely to be the successful drug for the treatment of prediabetes with statin therapy.

Background: Both airflow limitation and smoking are established cardiovascular risk factors. However, their interaction as risk factors for the development of atherosclerosis in coronary artery disease patients remains unclear. Objectives: To evaluate the effect of the interaction between airflow limitation and smoking status on the severity of carotid atherosclerosis. Methods: We categorized the 234 enrolled patients with coronary artery disease into four groups: never-smokers with normal pulmonary function (group A), never-smokers with airflow limitation (group B), ever-smokers with normal pulmonary function (group C), and ever-smokers with airflow limitation (group D). Results: The prevalence of airflow limitation in the enrolled patients was 23.1% (ever-smokers: 15.8%, never-smokers: 7.3%). The prevalence of severe carotid atherosclerosis was 28.2, 29.4, 41.3, and 45.9%, respectively, in the four groups (group D vs. group A, p = 0.035). Even after multivariate adjusting for confounding factors, ever-smokers with airflow limitation were independently associated with severe carotid atherosclerosis (odds ratio 2.89, 95% confidence interval, 1.19-7.00, p = 0.019). Conclusions: Ever-smokers with airflow limitation were significantly associated with severe carotid atherosclerosis among patients with coronary artery disease. These findings also provide additional insight into the correlation between airflow limitation and poor cardiovascular clinical outcomes.

While the prevalence of non-communicable disease risk factors is understood to be higher among migrants than for people born in host nations, little is known about the dementia risk profile of migrants, refugees and asylum seekers. This systematic review examines published literature to understand what is currently reported about 12 identified modifiable risk factors for dementia among migrants, refugees, and asylum seekers residing in Australia. Three literature databases (PubMed/CINAHL/MEDLINE) were systematically searched to find articles reporting excessive alcohol consumption, traumatic brain injury, air pollution, lack of education, hypertension, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and limited social contact in Australia’s migrant, refugee and asylum seeker population samples. Papers were systematically reviewed following PRISMA guidelines. A total of 763 studies were found, of which 676 articles were excluded, and 79 articles remained. Despite wide variability in study design, size and purpose, the prevalence and correlates of modifiable risk factors of dementia appears markedly different among the studied samples. Compared with Australian-born participants, migrant samples had a higher prevalence of depression, social isolation, physical inactivity and diabetes mellitus. Insufficient information or conflicting evidence prevented inference about prevalence and correlates for the remaining dementia risk factors. A better understanding of the prevalence and correlates of modifiable dementia risk factors is needed in Australia’s migrant, refugee and asylum seeker populations. This information, together with a deeper understanding of the contextual and cultural contributing factors affecting people who arrive in Australia through differing pathways is needed before preventive interventions can be realistically targeted and sensitively implemented.
