The most productive institute and author were Tehran University of Medical Sciences with 119 papers and Rezaei, N. L-Arginine molecular weight with 12 papers. Iranian researchers collaborated with the researchers of 73 countries, with the USA ranking first in Covid-19 research, followed by Italy, Canada, and United Kingdom. In publishing papers on COVID-19, Iran ranked first among the Middle Eastern countries and thirteenth internationally. Conclusion Iranian researchers were active in 5 main areas of COVID-19 research, including epidemiology, diagnosis, treatment, virology, and systematic review.Background The health sector evolution plan was implemented in 2014 in government hospitals across the country as a part of the universal health coverage achievement programs. This study assessed the performance of hospitals before and after the implementation of this plan, using the Pabon Lasso model. Methods The population of this study consisted of the hospitals of the country in the 2013-2015 time frame; overall, 874 hospitals (94.5% of the population) were included in the study. In order to assess performance, we used the Pabon Lasso model and hospital performance indicators (Average Length of Stay, Bed Turnover, and Bed Occupancy Rate). The data were collected from the Hospital Information System and provincial deputies of curative affairs and were then analyzed using the descriptive indicators of mean, frequency, and median in SPSS 22. Also, Paired Student T-test and ANOVA were used to compare the performance of different groups of hospitals before and after the implementation of the health sector evol has reduced the difference in the performance of hospitals. Equal support of government hospitals along with financial protection against health expenses, improves the performance indicators of hospitals and reduces performance differences among them.Background Lung cancer accounts for about 13% of all cancers and about 60% of patients with lung cancer also experience weight loss during treatment. There seems to be a clear correlation between the therapeutic outcomes of patients based on their weight changes during treatment. The aim of this study was to investigate the relationship between weight changes during and after treatment and the therapeutic outcomes of a patient with metastatic lung cancer. Methods This cohort study was performed on patients with the diagnosis of non-surgical metastatic lung cancer referred to Hematology and Oncology Clinic, Rasoul-e-Akram Hospital. Patients were divided into two groups with a weight gain of more than 5% and a weight gain of 5% and less. The information was entered into the SPSS version 21 software. In the descriptive analysis, mean and standard deviation (SD) were used. To compare quantitative variables, independent samples t-test, Mann-Whitney, chi-square or Fisher exact tests were used to compare qualitative variables and correlation test was used to determine the correlation between quantitative data. Survival curves were used to show differences in two groups of studies. A regression model was used to calculate the hazard ratio. The significance level was less than 0.05. Results Sixty patients, including 40 males (66.7%) and 20 females (33.3%) were studied. The mean age of patients was 62.22±9.00 years (43-83 years). The mean weight changes in the patients were -1.28±6.11 kg (-16 to 16kg). Forty-seven patients (78.3%) had weight gain less than 5%. There was no significant difference in overall survival (OS) and progression-free survival (PFS) according to weight gain. Conclusion Finally, the findings of the study showed that, despite the fact that PFS and OS in the weight gain group were greater than 5% of the original weight; the difference was not statistically significant.Background Current Health care delivery systems are not effective for the elderly. Countries with high elderly populations are expected to design special models to serve their elderly population. The aim of this study is to investigate the models of health care delivery to the elderly in different countries. Methods The present study is a systematic review based on PRISMA standard guidelines. The search for related studies was conducted in electronic databases (Cochran Library, Scopus, PubMed, Embase, Web of Science) and the Google Scholar search engine without time limits until May 2019. Keywords were extracted based on MeSH strategies. At first, 16243 articles were found. After the screening phase (elimination of duplicated articles, title screening, abstract screening, and full-text screening) 19 articles remained. Two articles deleted after text appraisal using the CASP checklist. In the next stage, after reviewing the gray literature and reviewing the references of remaining articles, three new articles were added (Included studies = 20). Results Twenty articles (models) corresponding to the study objectives were finally extracted. These models are limited to nine countries and most have local scopes. These models mainly use a case manager, an intra- or inter-disciplinary team, and an elderly assessment tool in their structure. In addition to the use of an information system, these models provide a wide range of services to the elderly. Conclusion Most of the models mentioned are local models. Smaller models to become applicable at the national level, they need to be reviewed and evaluated by policymakers and experts. Given the inefficiency of current systems in providing services to the elderly, it is recommended that countries use an integrated model of health care provision for the elderly.

The literature regarding reconstruction of foot bone defects is limited. The reconstruction of diaphyseal bone defects is technically challenging and is often associated with poor outcomes. Associated osteomyelitis adversely affects the healing rates following a reconstruction procedure.

We report a case of a 62-year-old male with lytic lesion involving the head of first metatarsal and proximal part of proximal phalanx following osteomyelitis treated with a two-stage reconstruction utilizing a modification of Masquelet's-induced membrane technique. A follow-up at 24 months post-surgery revealed a fully incorporated fibular graft with satisfactory functional outcomes.

This two-stage modification of Masquelet technique provided an effective method to reconstruct the defect and restoration of the metatarsal length using minimal hardware to achieve a good functional recovery of the patient.
