Abstract
INTRODUCTION Silicosis mostly happens in workers with high silica exposure and may accompany the development of various diseases like tuberculosis, cancer, or autoimmune diseases. The term silico-tuberculosis describes a condition in which an individual is affected by both silicosis and tuberculosis at the same time. This systematic review and meta-analysis study was conducted to evaluate the risk of tuberculosis in silicosis patients and individuals exposed to silica dust. METHODS We performed a systematic search for relevant studies up to 6 September 2022 using PubMed/ Medline, and Embase with the following keywords in titles or abstracts: "silicosis" OR "silicoses" OR "pneumoconiosis" OR "pneumoconioses" AND "tuberculosis". Cohort and case-control studies containing relevant and original information about tuberculosis infection in silicosis patients were included for further analysis. Pooled estimates and 95% confidence intervals (CI) for the relative risk of tuberculosis in individuals with silicosis compared to those without; these were evaluated using the random effects model due to the estimated heterogeneity of the true effect sizes. RESULTS Out of 5352 potentially relevant articles, 7 studies were eligible for systematic review, of which 4 cohort studies were included for meta-analysis. The total population of all studies was 5884, and 90.63% were male. The mean age of participants was 47.7 years. Our meta-analysis revealed a pooled risk ratio of 1.35 (95%CI 1.18-1.53, I 2: 94.30%) which means an increased risk of silicosis patients and silica-exposed individuals to tuberculosis infection. CONCLUSION Silicosis and silica dust exposure increase the risk of tuberculosis. Therefore, we suggest that individuals with long-time silica exposure, like mine workers, be routinely considered for both silicosis and tuberculosis screening programs.

Abstract
ObjectiveDespite being the subject of many studies over the past two decades, mechanisms underlying psychogenic non-epileptic seizures (PNES) are still poorly understood. We tried to address this issue by utilizing brain functional connectivity analysis to identify brain regions with abnormal activities in patients with PNES. In a case-control study, we performed graph based network analysis, a robust technique that determines the organization of brain connectivity and characterizes topological properties of the brain networks.MethodsTwelve individuals with PNES and twenty-one healthy control subjects were examined. Resting state functional magnetic resonance imaging (rsfMRI) was acquired. All subjects were asked to keep their eyes open during the scanning process. The rsfMRI analysis consisted of pre-processing, extracting the functional connectivity matrix (FCM) based on the AAL atlas, threshold for binary FCM, constructing a graph network from FCM and extracting graph features, and finally statistical analysis. For all cortical and subcortical regions of the AAL atlas, we calculated measures of ‘degree,’ which is one of the features of the graph theory. Results: Our results revealed that, as compared to the healthy control subjects, patients with PNES had a significantly lower degree in some brain regions including their left and right insula (INS), right Putamen (PUT), left and right Supramarginal gyrus (SMG), right Middle occipital gyrus (MOG), and left and right Rolandic operculum (ROL). In contrast, degree was significantly greater in two regions [i.e., right Caudate (CAU) and left Inferior frontal gyrus orbital part (ORBinf)] in patients with PNES compared to that in controls.ConclusionOur findings suggest that functional connectivity of several major brain regions are different in patients with PNES compared with that in healthy individuals. While there is hypoactivity in regions important in perception, motor control, self- awareness, and cognitive functioning (e.g., insula) and also movement regulation (e.g., putamen), there is hyperactivity in areas involved in feedback processing (i.e., using information from past experiences to influence future actions and decisions) (e.g., caudate) in patients with PNES. The observation that individuals with PNES suffer from a wide range of abnormal activities in functional connectivity of their brain networks is consistent with the fact that PNES occur in a heterogeneous patient population; no single mechanism or contributing factor could explain PNES in all patients.

Abstract
We examined the functional connectivity of subcallosal cingulate gyrus (SCG), nucleus accumbens (NAc), and ventral caudate (VCa), the main target areas for the treatment of major depression disorder (MDD), using deep brain stimulation (DBS). MDD is one of the most common diseases in the world, and approximately 30% of MDD patients do not respond to common therapies, including psychotherapy and antidepressant medications. Alternatively, DBS has been recently used to treat MDD. Resting state fMRI was obtained from seventeen healthy subjects and seven MDD patients. The functional connectivity network of the brain was constructed for all subjects and measured by the `degree' value for each SCG, NAc, and VCa regions using the graph theory analysis. The results show that the degree values of VCa and the left SCG are higher in the MDD group than the healthy group. Furthermore, the patterns of the degree values were different for the right and left hemispheres in MDD patients. Our findings suggest that degree values and their patterns have a potential to be used as diagnosis tools to detect the brain areas with abnormal functional connectivity.

Abstract
OBJECTIVE The aim of the study was to determine the effect of mindfulness-based stress reduction (MBSR) intervention on emotion regulation and glycemic control of patients with type 2 diabetes. MATERIALS AND METHODS Sixty patients with type 2 diabetes were recruited for this randomized controlled trial from an outpatient clinic at Imam Hospital in Iran. The intervention group participated in 8 sessions of MBSR, and the control group continued the treatment as usual. Fasting blood sugar and HbA1c were measured as two indices of glycemic control. Overall mental health, depression, and anxiety were measured using the General Health Questionnaire (GHQ-28), Hamilton Depression Rating Scale (HDRS), and Hamilton Anxiety Rating Scale (HARS), respectively. All the assessments were performed at baseline and after 8 weeks and 3 months as follow-up. RESULTS In comparison with the control group, the MBSR intervention group showed a significant reduction on all outcome measures including FBS, HbA1C, HARS, and HDRS scores (p < 0/05). CONCLUSION MBSR had a remarkable improvement on emotional wellbeing and glycemic control of patients with type 2 diabetes.

Abstract
WHAT IS KNOWN AND OBJECTIVE Current treatments for depressive disorders are far from optimum. This study was planned to evaluate possible antidepressant effects and safety of memantine, a selective N-methyl-d-aspartate receptor antagonist, in humans. METHODS Sixty-six outpatients with the diagnosis of moderate-to-severe major depressive disorder, based on DSM-V diagnostic criteria, were recruited to participate in a parallel, randomized, controlled trial. Sixty-two participants completed 6 weeks of treatment with either memantine (20 mg/day) plus sertraline (200 mg/day) or placebo plus sertraline (200 mg/day). Patients were evaluated using the Hamilton Depression Rating Scale (HDRS) at baseline and at weeks 2, 4 and 6. Comparison of treatment efficacy in improving depressive symptoms between the two groups was the principal outcome measure. RESULTS AND DISCUSSION A repeated-measures analysis demonstrated significant time × treatment interaction on HDRS score [F (2·09, 125·67) = 5·09, P = 0·007]. Significantly greater improvement was seen at all three follow-up sessions as well as significantly greater response rates at weeks 4 and 6 (P = 0·018 and P < 0·001, respectively) in the memantine group. Significantly more early improvers and more rapid response to treatment were observed in the memantine group (P = 0·001 and P < 0·001, respectively). A significant reduction was observed in HDRS score from baseline to the study endpoint in both memantine (P < 0·001, Cohen's d = 12·71) and placebo groups (P < 0·001, Cohen's d = 5·13). No serious adverse event occurred. No significantly greater remission rate was seen in the adjunctive memantine therapy. WHAT IS NEW AND CONCLUSION A 6-week course of treatment with memantine as adjunct to sertraline showed a favourable safety and efficacy profile in patients with major depressive disorder. Nonetheless, larger controlled studies of longer duration are necessary to assess long-term safety, efficacy and optimal dosing.

Abstract
It is well recognized that the quality of host plants affects the development and survival of twospotted spider mite Tetranychus urticae Koch. The life table parameters of T. urticae, on six cultivars of common bean (Phaseolus vulgaris L.) (chiti Khomein, chiti Ks21189, red Akhtar, red Ks31169, white Pak, and white G11867) were studied at constant laboratory conditions (27 +/- 2 degrees C, 70 +/- 5% RH and 16:8 L:D). Total development times of immature males and females were significantly influenced by bean cultivar. T. urticae laid significantly more eggs per day on red Akhtar (16.16) than on the other cultivars. The mean generation time ranged from 23.37 to 34.82 d, and a significant varietal effect was seen. Percentage of egg hatchability oftwospotted spider mite ranged from 88.25 to 94.20%. The highest intrinsic rate of increase, was recorded on red Akhtar (0.269 +/- 0.031) and the lowest value was obtained on white Pak (0.129 +/- 0.048). In addition, net reproductive rate and finite rate of increase of the twospotted spider mite had the highest value on red Akhtar: 62.38 +/- 1.05 and 1.30 +/- 1.02, respectively. The lowest values of these parameters were recorded on white Pak as 26.11 +/- 1.40 and 1.13 +/- 1.10, respectively. Doubling time varied significantly on different cultivars and the lowest and highest values were obtained on red Akhtar and white Pak, respectively. Our findings revealed that white beans (Pak and G11867) were less suitable cultivars, suggesting that they are more resistant to the twospotted spider mite than the other cultivars.

Abstract
Premenstrual syndrome (PMS) is a distressing group of symptoms related to menstrual cycle during reproductive age. Its substantial burden on daily function and quality of life, particularly on mental aspects, was to the impetus for this study with the aim of determining the effectiveness of a psycho-educational package on premenstrual syndrome and related symptoms. In a randomized clinical trial, 123 (17-19-year-old) adolescent girls with PMS were randomized to psycho-educational intervention (including 62 subjects) and control (including 61) groups. The participants completed a demographic questionnaire, premenstrual syndrome symptom daily record scale and the Symptom Checklist-90-Revised (SCL-90-R). A paired and two independent samples t-test and chi-squared test were used for analysing data using SPSS statistical package. At the end of the study there was statistically significant decrease in severity of total PMS in intervention compared with control group (P < 0.001). Also, a significant difference in somatization, anxiety and hostility was observed between two groups (P < 0.05). However, depression marginally decreased (P < 0.1) in intervention group, and interpersonal sensitivity was not statistically different between intervention and control groups. Intervention alleviated the severity of PMS and related somatization, anxiety and hostility, yet it could not change the severity of depression and interpersonal sensitivity.

Abstract
BACKGROUND Cutaneous leishmaniasis is still a health problem in many rural and urban regions of Iran and drug resistance has emerged as a major impediment in the treatment of leishmaniasis. This study aims to determine the drug resistance gene in cutaneous leishmaniasis by PCR in some endemic areas of Iran. METHODS Ninety seven samples were collected from ulcers of leishmaniasis patients from some endemic areas of Iran. The Giemsa stained samples were examined microscopically and cultured in NNN and RPMI 1640 mediums for parasite detection. After DNA extraction, PCR was done by a pair of specific primers. For detection of mutation in DNA, first PCR products were electrophoresed on CSGE gel. The suspected samples were compared by sequencing and RFLP results were demonstrated. Comparison of DNA derived from a wild type cell and mutant cell was undertaken by CSGE and sequencing methods. RESULTS Among 90 isolates (92.8%) examined for detection of mutation in gene with CSGE and RFLP, 10 (11.1%) revealed a disorder in sequencing selection for unresponsive to drug. CONCLUSION Drug resistance in cutaneous leishmaniasis to sodium stiboglocanat is probably due to a mutation in a genome. A field study is needed to determine the distribution of drug resistance and other gene mutations involved in unresponsiveness to drugs in leishmaniasis endemic areas of Iran.

Abstract
BACKGROUND Trichomoniasis is a worldwide protozoan parasitic disease and metronidazole is a choice drug for its treatment. Because of disease importance in public health and its controversial ideas about the prevalence of drug resistance, this study was carried out. METHODS Fifty-two suspected vaginal samples were collected from 2006 to 2007 in Gynecology Maryam Hospital, Tehran, Iran. All isolates were examined by microscopic, culture and PCR techniques. The PCR products were analyzed by RFLP and CSGE methods and two suspected samples were sequenced. RESULTS Trichomonas vaginalis was identified from all 52 samples. Of 52 isolates, 45 samples were successfully cultured and amplified by PCR except one. Seven were positive only by PCR. Finally, ITS1 fragment was successfully amplified in 51 of 52. CSGE analysis and PCR products digestion by MspI followed by sequencing showed nucleotide mutation at position 209 (C209T) of the ITS1 fragment in two (3.9%) of them. CONCLUSION The results showed mutation in ITS1 fragment of T. vaginalis in two (3.9%) of Iranian isolates which may be related to metronidazole resistance.

Abstract
Background: Insulin-like growth factor-binding protein 7 (IGFBP7) is an abundant, selective and accessible biomarker of glioblastoma multiforme (GBM) tumour vessels. In this study, an anti-IGFBP7 single-domain antibody (sdAb) was developed to target GBM vessels for molecular imaging applications. Methods: Human GBM was modelled in mice by intracranial implantation of U87MG.EGFRvIII cells. An anti-IGFBP7 sdAb, isolated from an immune llama library by panning, was assessed in vitro for its binding affinity using surface plasmon resonance and by ex vivo immunobinding on mouse and human GBM tissue. Tumour targeting by Cy5.5-labelled anti-IGFBP7 sdAb as well as by anti-IGFBP7 sdAb conjugated to PEGylated Fe3O4 nanoparticles (NPs)-Cy5.5 were assessed in U87MG.EGFRvIII tumour-bearing mice in vivo using optical imaging and in brain sections using fluorescent microscopy. Results: Surface plasmon resonance analyses revealed a medium affinity (KD=40–50 nM) binding of the anti-IGFBP7 sdAb to the purified antigen. The anti-IGFBP7 sdAb also selectively bound to both mouse and human GBM vessels, but not normal brain vessels in tissue sections. In vivo, intravenously injected anti-IGFBP7 sdAb-Cy5.5 bound to GBM vessels creating high imaging signal in the intracranial tumour. Similarly, the anti-IGFBP7 sdAb-functionalised PEGylated Fe3O4 NP-Cy5.5 demonstrated enhanced tumour signal compared with non-targeted NPs. Fluorescent microscopy confirmed the presence of anti-IGFBP7 sdAb and anti-IGFBP7 sdAb-PEGylated Fe3O4 NPs selectively in GBM vessels. Conclusions: Anti-IGFBP7 sdAbs are novel GBM vessel-targeting moieties suitable for molecular imaging.

Abstract
BACKGROUND AND AIMS Psycho-dermatology addresses the interaction between mind and the skin. Effective management of at least one third of the patients attending the skin department depends, to some extent, upon the recognition of emotional and psychologic factors. The aim of this study was to provide epidemiologic data about common psycho-dermatoses and their prevalence in dermatologic patients in Iran. MATERIALS AND METHODS Patients suspicious to have psychocutaneous problem with primary dermatologic chief complaint were included. After detailed dermatologic evaluation, all patients were visited by an expert psychologist to determine prevalence of DSM-IV disorders in each psychocutaneous category including delusion of parasitosis, trichotillomania, dermatitis artefacta and neurotic excoriation. RESULTS A total of 178 patients including 78 (43.8%) males and 100 (56.2%) females entered the study. The commonest psychocutaneous disorder was neurotic excoriation followed by trichotillomania, delusion of parasitosis and dermatitis artefacta. Mood disorder was the commonest DSM-IV disorder in our patients, then anxiety disorder and drug-induced symptoms. CONCLUSION According to our results, it seems that all psychocutaneous disorders but delusion of parasitosis are commoner in females. Mood and anxiety disorders were common in patients with dermatitis artefacta, as patients with neurotic excoriation. In trichotillomania, obsessive compulsive disorder was the commonest disorder. Drug abuse is a major background of delusional parasitosis.

Abstract
BACKGROUND The Prochaska model of readiness to change has been proposed to be used in educational interventions to improve medical care. OBJECTIVE To evaluate the impact on readiness to change of an educational intervention on management of depressive disorders based on a modified version of the Prochaska model in comparison with a standard programme of continuing medical education (CME). METHODS This is a randomized controlled trial within primary care practices in southern Tehran, Iran. The participants included 192 general physicians working in primary care (GPs) were recruited after random selection and randomized to intervention (96) and control (96). Intervention consisted of interactive, learner-centred educational methods in large and small group settings depending on the GPs' stages of readiness to change. Change in stage of readiness to change measured by the modified version of the Prochaska questionnaire was the RESULTS The final number of participants was 78 (81%) in the intervention arm and 81 (84%) in the control arm. Significantly (P < 0.01), more GPs (57/96 = 59% versus 12/96 = 12%) in the intervention group changed to higher stages of readiness to change. The intervention effect was 46% points (P < 0.001) and 50% points (P < 0.001) in the large and small group setting, respectively. CONCLUSIONS Educational formats that suit different stages of learning can support primary care doctors to reach higher stages of behavioural change in the topic of depressive disorders. Our findings have practical implications for conducting CME programmes in Iran and are possibly also applicable in other parts of the world.
