 The purpose of this study was to analyze the co-occurrence of the terms of medical and laboratory equipment patents in the United States Patent and Trademark Office between 1984 and 2014.  This research was an applied study using scientometrics and co-word analyses. The statistical population of the present study included all patents of medical and laboratory equipment registered in the United States Patent and Trademark Office database between 1984 and 2014. As a result, a total of 13424 patents were retrieved.  The results revealed that in terms of frequency, the keyword "Menstrual Fluid" and in terms of co-occurrence, two keywords (Menstrual Fluid and Magnetic Resonance Image Apparatus) were the most frequent ones in medical and laboratory equipment studies. The results of hierarchical clustering with "Ward's method" led to the formation of eight clusters in this area including the following: General Equipment, Rehabilitation Equipment, Dental Equipment, Therapeutic Equipment, Emergency Equipment, Laboratory Equipment, Diagnostic Equipment, and Medical Consumables. The analysis of the co-occurrence of words revealed the scientific structure of medical and laboratory equipment well. Accordingly, the scientific issues were extracted and the relationship between them was discovered. The maps of co-word analysis showed several changes, sustainability of concepts, and terms related to this field of science.

One of the important dimensions of access to health services is uniform distribution. A survey on the distribution of health and treatment indices in different regions reveals inequalities in order to reduce inequalities. The study aims to rank the cities of Sistan and Baluchestan province from the perspective of access to healthcare services.

This is a descriptive-applied and cross-sectional study. The data were collected from the database of Statistical Center of Iran. The studied indices were weighted by Shannon entropy method, and the ranking of cities was done by TOPSIS method. The distribution of health services among the cities was shown by Spearman and Kendall correlation coefficient. Also, with the coefficient of variation, the important indices for creating imbalances were determined.

The results of TOPSIS method showed a significant difference between the levels of access to health services indices. Zabol and Zahedan cities ranked first and second, and the cities of Ghasreghand, Sibsuran and Fanuj were in the last rank, respectively. Among the factors that led to a level difference, the number of PhDs, laboratory sciences doctors and rehabilitation centers caused the greatest difference between the cities. The findings show that there is little correlation between demographic rank and access to healthcare services, and health services are not distributed equitably according to the population.

More attention to cities that are ranked below the level of access to healthcare resources is needed. More healthcare resources should be given to this province because there are few healthcare indices relative to its population.

Despite the significant progress in the field of health, Cardiovascular diseases are the leading cause of death among people. For this purpose, the present study was conducted to evaluate the effect of eight weeks of aerobic exercise on lipoprotein a, blood coagulation and fibrinolysis factors in overweight women. In this semi experimental study with pre and post-test design, 21 overweight women subjects aged between 20 and 30 were randomly selected from experimental (10 people) and control (11 people). The aerobic exercise protocol consisted of five sessions per week for 30 minutes and with an intensity of 55%-75% heart rate reserve (HRR). Blood samples were collected from subjects in two stages to evaluate the considered variables. Measurement of levels of Lipoprotein a, Fibrinogen, PT, PTT, Platelet counts and Hemoglobin. For data analysis, repeated measures of variance analysis at a significant level of 5 hundredths were used by employing SPSS software. The mean values of Lipoprotein a, Fibrinogen, PT and Platelet counts in the control group showed no significant change after eight weeks of training (P>0.05). While PTT changes in the both groups was significant in the post-test compared to the pre-test (P=0.006). The inter-group difference, in any of the variables between the experimental and control groups, was not significant (P>0.05). Eight weeks of aerobic training had no effect on Lipoprotein a and blood coagulation and fibrinolysis factors, however, this training program can take effective steps in improving health promotion in overweight women.
