Background and Aim: To describe the trends in research articles in the field of mental health.
Materials and Methods: The articles that we reviewed belonged to the fields of psychiatry, psychology, and neuroscience. We limited the search to the literature published over the 30-year period from 1973 to 2002. The following types of data were extracted: areas of research, specific topics, study design, location for data collection, funding sources, and the different types of working relationship among the authors.
Results: Analysis of publication trends in 3031 articles showed a marked increase in the total number of publications with time, especially over the last 5 years. As for different research areas, we detected a growing proportion of articles in the field of neuroscience and a decline in articles dealing with mental health. The volume of research in the fields of psychology, epidemiology and clinical sciences remained relatively constant. There was a rise in the proportion of cross-sectional studies and clinical trials in the second half of the 30-year period.
Conclusion: It is important to find the reasons and implications for the waning interest in mental health. Our results could provide an empirical basis in policy making and strategic planning for research in this area

  ABSTRACT

 

  Background and Aim: Air pollution is one of the most important problems of big cities in developing countries and can have several negative health effects on humans. Therefore studying these pollutants can help in developing programs for air pollution control. The aim of this study was to estimate and predict the changes of air pollutants in Kerman, Iran.

  Materials and Methods: In this ecological study, data about seven important air pollutants in Kerman including NO, CO, NO₂, NO_x, PM₁₀, SO₂ and O₃ from March 2006 until September 2010 was inquired from the Kerman Province Environmental Protection Agency. Then the data was calculated as averages per month and by incorporating time series models, predictions were done for each pollutant.

  Results: All of the pollutants were steady in Kerman, except CO which is significantly decreasing and PM₁₀ which is increasing. All of the pollutants had a seasonal pattern. Time series models with a 12, 3, 8, 12, 12, 12 and 6 month seasonal pattern were fit for O₃ , SO₂ , PM₁₀ , NO_x , NO₂ , CO and NO consecutively.

  Conclusion: The production of ambient CO is decreasing in Kerman and one reason is probably replacing and retiring old automobiles. However PM₁₀ is increasing in Kerman and in most seasons it is above standard and therefore control initiatives should be implemented.

Background and Aim: Lipoprotein disorders are an integral component of type-2 diabetes mellitus (T2DM). Therefore, early diagnosis and treatment of lipid disorders can be beneficial in prevention and treatment of many complications associated with T2DM.The aim of this study wasto determine the effect of docosahexaenoic acid (DHA) supplementation on the serum levels of apolipoproteins (Apos) A1, A2, B48 and C3 in patients withT2DM.
Materials and Methods: In this 8-week randomized, double-blind, placebo-controlled clinical trial, 44 T2DMpatients were randomly assigned to either an experimental group (n=22, receiving daily 2.4 g DHA) or a placebo group (n = 22, receiving paraffin). The serum levels of AposA1, A2, B48 and C3 were measured in all the patients at the beginning and at the end of the period.
Results: There was a statistically significant increase in the mean serum level of ApoA1 in the DHA group (p = 0.014). In addition, a significant difference was observed in the serum level of ApoC3 after intervention between the DHA and placebo group (p=0.031). There were no significant differences between the two groups as regards the mean changes in serum levels of ApoA1, ApoA2, ApoB48 and ApoC3.
Conclusions: Dietary supplementation with docosahexaenoic acidhasno effects on the serum levels of apolipoproteins in patients with type-2 diabetes.
