We aimed to investigate the patterns of incidence and prevalence of bone sarcoma (BS) and soft tissue sarcoma (STS), morphology as well as geographical distribution in the elderly in Iran.

By the primary site of the tumor and the morphological types, whole cases of cancer were classified. Then, the WHO classification (2018) and the third revision of the standard International Classification of Diseases for Oncology (ICD-O-3) were used to assign a code to them. The estimated incidence rates were obtained as the frequency of the newly-diagnosed cases within one year divided by the calculated population of the mid-year Iranian residents as estimated by the Iranian Bureau of Statistics. The age-standardized incidence rates were also estimated for both bone and soft tissue sarcoma.

The annual crude incidence rates of sarcomas in males (0.80 per 100,000) were more than in females (0.55 per 100,000) in all years. The total combined crude incidence in 2014 years was obtained at 0.67 per 100,000 people. In terms of disease grade majority of the patients were of grade 3 (11.5 %). In terms of tumor location, the Lower extremity was 16.8%, the Visceral (including gastrointestinal & uterus) 15.8%, the Thoracic 12.8%, and the Pelvic & abdominal wall 9.7%.

Even though such sarcoma is more prevalent in elderly men, its incidence was also observed in lower-aged female groups. In addition, the incidence rate of BS was lower in comparison with that of STS, and the patients often exhibited an unknown degree of sarcoma.

 Considering the importance of physician-nurse relationship in emergency departments and its role in improving the quality of services, patient satisfaction, job success and staff satisfaction, this study was conducted to investigate nurses' attitude about the professional doctor-nurse relationship and career success of the nurses in emergency departments.

 This study is a descriptive study in which 197 nurses working in the emergency departments of hospitals affiliated to Tabriz University of Medical Sciences participated. Data collection tools included demographic characteristic; physician-nurse professional communication questionnaire and nurses' career success questionnaire. The collected data were analyzed using descriptive and inferential statistical tests with SPSS ver.21 statistical software.

  The findings showed that the mean (SD) of the professional physician-nurse relationship from the perspective of participating nurses was 3.07 (0.54). Cooperating dimension with the mean score of 3.34 (0.79) had the highest score and imposing opinions and tasks dimension with the mean score of 2.62 (0.85) had the lowest score. Also, the mean (SD) score of nurses’ career success was 4.21 (0.40) with the highest mean in the dimension of system assistant 4.33 (0.55) and the lowest mean in the effective dimension 4.08 (0.41).

Considering the importance of the professional physician-nurse relationship, it is necessary to pay more attention to the effective factors in its promotion by implementing interventions such as professional communication skills training and effective interaction in strengthening the professional relationship of the treatment team.

Practical Implications: 

 The results of this study can be used to improve professional communication between health care team members and their work success. As a result, in addition to increasing job satisfaction and improving the psychological condition of personnel, the safety of patients will also be increased and the amount of injuries caused by communication defects will be decreased.

The aim of the current research is to provide a framework on the development of lean innovation in electronic businesses. The approach of the current research is qualitative, in terms of practical purpose and in terms of nature and exploratory method. The statistical population of the research consists of experts and activists in the field of E-businesses with more than five years of relevant work experience, which has reached the saturation stage with the snowball sampling method and the semi-structured interview tool in sample 13. In this study, the six-step thematic analysis of Brown and Clark (2006) was used for analysis. Thematic analysis of the data in this research led to the discovery and labeling of 64 concepts and propositions as primary themes, 10 concepts as organizing themes and four concepts as overarching themes. To develop lean innovation, e-businesses need special tools such as joint design, change and risk management, along with clarifying goals and team building, as well as protecting users' privacy and finally commercializing knowledge. In the meantime, choosing the right platforms, transparent and continuous evaluation, using new analytical techniques in monitoring the behavior of users and competitors, as well as focusing on fintechs as a new financial technology are also effective.

Delay in diagnosis of diabetes mellitus (DM) in older adults is more catastrophic than other age groups. This study investigated the prevalence of pre‑diabetes, DM, and glycemic control in the elderly.

In this cross‑sectional study, a sample of 412 older adults >60 years from Shiraz, Iran, were recruited through a multistage cluster random sampling. Demographic, clinical, and laboratory information were collected by interview, physical examination, and reviewing the medical records. Data were analyzed using SPSS 20.

Mean age was 68.1 ± 6.2 years and female‑to‑male ratio was 1.1. Out of all, 137 (33.2%) were diagnosed as diabetic including 128 (31%) as known cases and 9 (2.2%) as new cases of DM, whereas 275 (66.7%) were diagnosed as new cases of pre‑diabetes. Multivariable analysis showed that low level of education (OR = 5.2, 95% CI: 1.5–16.6), hyperlipidemia (OR = 3.5, 95% CI: 2.1–5.8), liver disease (OR = 3.1, 95% CI: 1.4–6.9), and hypertension (HTN) (OR = 1.9, 95% CI: 1.1‑3.2) were the most common predictors of DM in the elderly, respectively. Out of all diabetics, 33.6% had FBS >130 mg/dL and 25.5% had HbA1c >8%, whereas these figures were ≥100 mg/dL and ≥5.7% in 36.7% and 21.4% of pre‑diabetics, respectively.

The pre‑diabetic elderly were mostly undiagnosed, while one‑third to one‑fourth of DMs had poor glycemic indices. These figures show the need for pre‑diabetes and diabetes screening in the elderly, especially in those with low level of education, hyperlipidemia, liver disease, or HTN. Furthermore, regular monitoring of glycemic indices in the diabetic and pre‑diabetic elderly is recommended.
