Prisoners are at greater risk of infectious diseases compared to the general population. While imprisoned, it is often difficult to observe Coronavirus 2019 (COVID-19) prevention strategies such as social distancing. To the authors’ knowledge, no study has been conducted worldwide to examine the condition of female prisoners with COVID-19. Therefore, this study aims to investigate the epidemiological, clinical and imaging characteristics of prisoners with COVID-19 in Ahvaz Women’s Prison (southwest, Iran).

The data for this descriptive cross-sectional study was collected using a checklist including epidemiological information, clinical symptoms, X-ray and computed tomography scan findings of the chest, underlying diseases and the final status of all female prisoners whose COVID-19 test was positive.

This study included 139 female prisoners with COVID-19 with a mean age of 37.19 ± 12.67 years. The most common underlying diseases were hypertension (14.4%), obesity (10.8%) and chronic obstructive pulmonary disease (9.4%). The most common symptoms at the onset of the disease were myalgia (59.0%), cough (41.0%) and dyspnea (37.4%). The most common radiological symptoms were ground-glass opacity (12.9%) and atelectasis (7.2%). In terms of extension of involvement, both lungs were involved in 8.6% of patients. In terms of zonal involvement, the lower lobes were more involved (8.6%). In terms of involvement position, the most common was sub-pleural (10.1%). None of the patients died.

Because the incidence, morbidity and mortality rate of COVID-19 in the prison population are likely to differ from those of the public. This study sought to investigate the situation of prisoners with COVID-19 in Ahvaz Prison, Khuzestan Province. To the best of the authors’ knowledge, this is the first worldwide study in this regard in women’s prisons.

This paper aims to focus on reducing the vulnerability of Ahvaz city against urban disasters and lowering the number of casualties and amount of financial losses using modern approaches to develop resilience strategies that can increase urban safety to an acceptable level. The strategic situation of Ahvaz city, because of its abundant resources, the war experience and its location on the boundary regions of Iran, highlights its significance. Ahvaz has a high population and an extended texture, and the existence of extraordinary constructions increases the importance of physical resilience in this city.

The present study investigates built environment aspects such as the urban structure, the urban form, land-use proximity pattern, urban road network and crucial and vulnerable centres in Ahvaz, using a combination of qualitative and quantitative methods. Hence, the areas at risk in Ahvaz were identified and illustrated in a comprehensive risk assessment map, and then, by using the strengths, weaknesses, opportunities and threats technique and finally by using the Delphi method, some strategies and plans were presented to reduce the level of vulnerability in Ahvaz. Then, these strategies are prioritized by applying quality function deployment (QFD) technique.

The risk assessment result shows that most parts of Ahvaz’s urban areas are highly at risk. The central and northern parts of Ahvaz have the highest vulnerability at a time of crisis. These zones include district 1 (city centre) and districts 2, 3 and 7 at the city’s margins. The result of QFD process showed that the essential urban resilience strategy is to positively consider the passive defence studies with a physical resilience approach. Also, the proper distribution of strategic points in the city, moving the industrial and oil companies from the peripheral area, and facilitating access to vital, crucial centres to support urban regions are considered the most effective strategic plans.

This paper, with an integrated approach, examines and prioritizes the main physical problems of Ahvaz city based on the spatial analysis and opinions of experts. The physical strategies presented in this paper can significantly reduce the risks and increase the urban resilience of Ahvaz city in the face of crisis.

Heavy metals constitute one of the most hazardous substances that could be accumulated in biota coming from human activities such as agricultural and industrial wastes. This paper aims to study the levels of some of the most common heavy metals in muscles of the fish caught in the Karun River (Ahvaz, Iran) and to assess the health risks associated with their consumption.

In present study, the concentrations of three heavy metals (Pb, Cd and Cu) in the muscle of highly consumed fish species Ctenopharyngodon Idella (Cyprinidae) collected from three selected markets (Khoram Kooshk, Ahvaz-e Qadim and Padad Shahr; total number of samples was 45) in Ahvaz city and human health risk associated with their consumption were detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

The results indicated that the highest and lowest accumulated metal concentrations were related to Cu (20.36 ± 0.84) and Cd (0.53 ± 0.02), respectively. In addition, the mean difference for Pb and Cu across two pairwise of sampling sites were significant (Ahvaz-e Qadim and Khoram Kooshk, P for Pb = 0.025, P for Cu = 0.033; Ahvaz-e Qadim and Padad Shahr, p for Pb = 0.018, p for Cu = 0.039). The estimated daily intake of all metals in muscles of fish in this study were below the legal limit, and mean differences were not statistically significant among the sampling sites, except for Cu (Ahvaz-e Qadim and Khoram Kooshk, p = 0.048; Ahvaz-e Qadim and Padad Shahr, p = 0.041). Target hazard quotient values were also all below 1.

It can be concluded that the fishes from Ahvaz city markets are comparatively clean and do not constitute a risk for human health.

The purpose of this paper with meta-analysis is to clarify the effects of cranberry consumption on features of the metabolic syndrome of interest of all relevant randomized controlled trials (RCTs).

A systematic literature search was conducted on ISI web of science, PubMed, Embase, the Cochrane library and Google Scholar databases, to include trials published up to March 2019. Weighted mean differences (WMD) were calculated from a random or fixed-effects models. Between‐study heterogeneity was assessed by Cochrane’s test and I2 index.

Ten RCTs were included in this review which involving a total of 371 subjects. Our meta-analysis showed that cranberry consumption had beneficial effects on waist circumference (WMD −0.49, 95% CI −0.96 to −0.036; p = 0.034). No significant effect of cranberry consumption on fasting blood glucose, high-density lipoprotein cholesterol, triglycerides and blood pressure was found in this meta-analysis.

To the best of the authors’ knowledge, this is the first systematic review with meta-analysis of RCTs that investigate the effect of cranberry consumption on features of the metabolic syndrome.

Metabolic syndrome contains metabolic disorders that have association with other chronic diseases. Melatonin is a bioactive compound which is found in plants and also produced in the body. The purpose of this paper is to assess the effect of melatonin supplement on metabolic syndrome components, also leptin and adiponectin blood concentrations in patients with metabolic syndrome.

A double blind, placebo-controlled, randomized clinical trial was conducted on 70 subjects with metabolic syndrome. Participants received 6 mg/day melatonin or placebo before bedtime for 12 weeks. At the beginning and end of treatment period, blood samples were collected and biochemical parameters were measured. In addition, blood pressure and anthropometric indices were examined before and after the supplementation. Independent sample t-test was used to compare changes in metabolic syndrome components between the two study groups.

Results showed a significant reduction in waist circumference (−1.54 vs −0.04 cm; p = 0.036), systolic blood pressure (−3.52 vs 0.79 mmHg; p = 0.020), diastolic blood pressure (−1.50 vs 1.73 mmHg; p = 0.014), serum leptin concentration (−2.54 vs 0.27ng/ml; p = 0.041) and an elevation in high-density lipoprotein cholesterol (2.19 vs −0.79 mg/dl; p = 0.038) in the melatonin group compared to the placebo.

If insulin concentration had been measured, it might have revealed better interpretation of melatonin effect on fasting blood glucose.

This study showed that melatonin as a nutritional supplement improved most metabolic syndrome components and concentration of leptin in the melatonin group compared to the placebo.

This paper aims to study the impact of increasing number of competitors on the organisational learning (OL) in tourism small and medium-sized enterprises. The focus of this study is the tourism and travel agencies (TTAs) of the City of Ahvaz where the OL was studied within TTAs insofar as increasing the number of competitors is concerned. The underlying question in this paper is whether or not the increasing number of competitors affects OL in TTAs of the City of Ahvaz.

Using a longitudinal survey, OL was studied at individual, group and organisational levels. The research is based upon quantitative and qualitative methods. Owing to the small number of samples, in addition to questionnaire and quantitative analysis, authors made use of in-depth interviews. The first research was conducted in 2012, while the second one was done in 2014.

It was found that in 2012, with its limited number of competitors in the market, learning in these organisations was desirable at individual level and not at group or organisational levels. On the other hand, both the quantitative and qualitative methods in 2014, with the increased number of TTAs, suggested that the quality of learning were desirable in all organisational levels in that year.

Care should be taken in generalising the results of the research to other TTAs because the size of the sample in this study was small. Moreover, structure and performance of TTAs may be different among various regions. In addition to the said limitation, it must be noted that some variables such as experience, education and gender were not consider in analysing the results of the study. Furthermore, OL in the TTAs might be affected by other variables that were not considered in this study.

Originality of the study is to link “OL” to the “competition”. There is not any study with special focus on OL with approaching to competition, neither in travel and tourism literature nor in OL literature, and this study can be a starting point to raise further and future research and debates.

Post-partum depression (PPD) is a mood disorder that affects 20-40 per cent of women in their post-delivery period worldwide. The purpose of this paper is to compare dietary intakes of energy, macronutrients, cholesterol, saturated fatty acids (SFAs), mono-unsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), some micronutrients and antioxidants in PPD patients with healthy controls.

This case-control study was conducted on 163 women in postpartum period (81 PPD and 82 non-PPD) using Edinburgh questionnaire for the diagnosis of PPD. Dietary nutrients intake was assessed using 147-item semi-quantitative food frequency questionnaire (FFQ). Portion sizes of food items were converted to grams per day. Logistic regression models were used to estimate the association between tertiles of dietary intakes with the odds ratio (OR) of PPD.

According to the fully adjusted model, highest tertile compared to lowest tertile dietary intake of SFAs [OR = 0.01; 95 per cent confidence interval (CI) = 0.00, 0.01, p = 0.001], MUFAs (OR = 0.01; 95 per cent CI = 0.00, 0.02, p < 0.001), total fats (OR = 0.01; 95 per cent CI =0.00, 0.01, p < 0.001) and cholesterol (OR = 0.06 ; 95 per cent CI = 0.01, 0.08, p < 0.001), thiamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), riboflavin (OR = 0.10; 95 per cent CI = 0.02, 0.39, p < 0.001), pyridoxine (OR = 0.03; 95 per cent CI =0.01, 0.32, p < 0.001), folate (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), cobalamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001) , selenium (OR = 0.79 ; 95 per cent CI =1.36, 3.32, p < 0.001), iron (OR =0.68; 95 per cent CI = 0.24, 0.94, p < 0.001) and iodine (OR = 0.36; 95 per cent CI =1.10, 1.38, p < 0.001) had a protective effect on the incidence of PPD. Furthermore, higher intake of vitamin A and beta-cryptoxanthin can increase the incidence of PPD (OR =114.29; 95 per cent CI =17.85, 118.12, p < 0.001) and (OR = 4.85; 95 per cent CI = 1.49, 15.69, p = 0.015), respectively.

PPD may have destructive effects on the relationship between mother and infant. Results of previous studies demonstrated nutrients are required for the synthesis of neurotransmitters and have biochemical role in the nervous system.

This study aims to identify the effect of strawberry supplementation on some metabolic, inflammatory and oxidative parameters in adults with cardiovascular (CV) risk factors.

A systematic literature search was performed up to November 2020 using PubMed, Embase, Cochrane, Web of Sciences and Scopus databases. The pooled mean difference (MD) with 95% confidence interval (CI) was used to analyze the data by random-effects model. I² statistics and Cochrane risk of bias tool were used for investigating heterogeneity and quality of included studies, respectively.

In total, 13 randomized controlled trials with 488 participants were included. Strawberry supplementation significantly reduced diastolic blood pressure (MD = −2.1, 95% CI [−3.7, −0.42], P = 0.01), low-density lipoprotein cholesterol (−0.16, −0.30, −0.02, P = 0.03), high-sensitivity C-reactive protein (CRP) (−0.76, −1.4, −0.05, P < 0.001) and CRP (−0.31, −0.43, −0.18, P = 0.04). Leptin levels were raised in control group compared with participants who had received strawberry (0.65, 0.09 and 1.2, P = 0.02). The results of subgroup analysis based on the follow-up duration and supplementation dose showed that consumption of strawberry for more than eight weeks and 50 g day⁻¹ can significantly decrease some other CV risk factors compared to control group. Further, both higher follow-up duration and supplementation dose were more effective in increasing leptin levels of control group compared to intervention group.

The use of some useful plant foods such as strawberries by the pharmaceutical industry and the community health sector can greatly help improve people’s CV and metabolic health.

In spite of the importance of food intake in weight management and preventing chronic diseases, it remains difficult to predict how anxious people change their eating behaviour in exposure to bad or good moods. The purpose of the study was to investigate the interaction effect of anxiety and different moods on food intake and blood pressure in healthy women students.

A total of 82 women university students (18-30 years) participated in the study. Subjects completed a valid anxiety questionnaire at baseline to measure trait and state anxiety scores, then they were randomly divided into two groups to watch comedy and drama movies for mood induction. After watching, some snacks were presented, and then energy intake and blood pressure were measured.

Students who suffered from severe state anxiety, consumed more energy from food when they watched a dramatic movie (p = 0.014). Subjects who suffered from moderate level of state anxiety and watched a dramatic movie experienced more systolic and diastolic blood pressure compared with subjects who suffered from moderate state anxiety but watched the comedy (p = 0.043 and p = 0.041, for systolic and diastolic blood pressure respectively). More diastolic blood pressure was shown among students who watched the drama movie and suffered from a severe level of trait anxiety (p = 0.049).

Electrocardiography and stroke volume measurement were not used.

Our findings showed blood pressure elevation in anxious people when they experienced bad feeling such as sadness, and they also consumed more energy from food. Both of these factors are related to the occurrence of chronic disorders such as cardiovascular diseases.
