Hematopoietic stem cell transplantation (HSCT) is being used increasingly in an attempt to cure many hematological disorders. Obesity has become a world wide phenomenon and is a known risk factor for numerous medical conditions, but its role in transplant outcomes remained controversial. Total of 192 patients with acute leukemia who underwent sibling HLA matched HSCT were analyzed to find the effect of pre-transplant body mass index (BMI) on transplant outcomes such as time to engraftment, infections, graft vs. host disease (GvHD), and overall survival (OS) for the period of three yr (April 2006-March 2009). There was a significant correlation between higher pre-transplant BMI and shorter engraftment time (p = 0.010); but no relation between BMI and GvHD, infection, and OS was found. The results of this study showed that patients with higher BMI may have a shorter engraftment time; but lower, although not significant, survival rate compared to non-obese patients.
Background Physical inactivity enhances the risk of adverse health conditions such as non-communicable diseases, morbidity, and mortality among middle- and older-aged population. This study is aimed to design, implement, and evaluate a conceptual model of physical activity (PA) promotion among middle-aged Iranian women (MAIW). Methods An interventional study was conducted with 80 women aged between 30 and 59 years in intervention and control groups during 2018–2019. The subjects referred to health centers were selected by the available convenience sampling method. Data collection tools to assess the MAIW' PA level (metabolic equivalent tasks (MET)-min/week) included face-to-face interviews, body mass index (BMI) measurements, the four-question form of PA vital signs in the framework of Iran's Package of Essential Non-communicable (IraPEN) program, and the questionnaire is based on the Health Belief Model (HBM) constructs. Results The intervention led to a three-fold increase in the average PA (from 280.63 to 927.70 MET-min/week) of the intervention group. Although no significant difference in the BMI between both groups was found before the intervention, this educational program decreased the mean BMI from 30.36 to 28.83 kg/m2 (p = 0.01). After the intervention, the values of HBM-based perceived sensitivity/severity and self-efficacy were increased from 62.09 to 71.03% and from 27.01 to 83.15%, respectively (p < 0.0001). There were no significant differences in the cue to action and perceived benefits and barriers after the intervention. Conclusion The developed model by increasing the motivation of MAIW could remarkably improve the PA level with a decrease in their BMI.

Background: The role of family physicians (FPs) in the metropolitan area is critical in identifying risk factors for disease prevention/control and health promotion in various age groups. Understanding patients' preferences and interests in choosing a FP can be an effective and fundamental step in the success of this program. In this study factors affecting the FP selection by Iranian patients referred to health centers in the most populous areas in the south of Tehran were assessed and ranked. Methods: A sequential mixed-method (qualitative-quantitative) triangulation approach was designed with three subject groups of patients, physicians, and health officials. The Framework method was used to analyze interviews transcribed verbatim. After implementing an iterative thematic process, a 26-item quantitative questionnaire with high validity and reliability was drafted to evaluate the different factors. A convenient sampling method was used to select 400 subjects on a population-based scale to quantitatively rank the most critical selection factors as a mean score of items. Results: The selection factors were divided into six centralized codes, including FPs' ethics, individual, professional and performance factors; patients' underlying disease and individual health, and disease-related factors, office's location and management factors, democracy factors, economic factors, and social factors. After filling out the questionnaires, the most important factors in selecting FP were a specialist degree in family medicine (FM) (4.49 ± 0.70), performing accurate examinations with receiving a detailed medical history (4.43 ± 0.68), and spending enough time to visit patients (4.28 ± 0.75), respectively. However, the parameters such as being a fellow-citizen, being the same gender, and physician's appearance were of the least importance. Conclusion: There is a possibility to screen the most important factors affecting the FP choice through the combination of qualitative and quantitative studies. The first and last patients' priority was physicians' specialty in FM and being a fellow-citizen with them, respectively. The clinical and administrative healthcare systems should schedule the entire implementation process to oversee the doctor's professional commitment and setting the visit times of FP.
Since 1991, 2042 first hematopoietic stem cell transplants (HSCT) have been performed at the Hematology-Oncology and Stem Cell Transplantation Research Center at Tehran University of Medical Sciences. Acute myelogenous leukemia (548 patients), thalassemia major (335 patients) and acute lymphoblastic leukemia (275 patients) have been the most common transplanted disorders. There were 1418 cases that received allogeneic HSCT and 624 cases that have received autologous HSCT. The numbers of allogeneic and autologous HSCT have increased, but the allogeneic to autologous ratio has remained constant. The first peripheral blood hematopoietic stem cell transplantation was performed in 1996; since then, 1671 have been done. The donor types for 1418 allogeneic first HSCT were 1367 (96.4%) human leukocyte antigen (HLA) matched-identical siblings, 29 (2%) HLA-mismatched sibling/other relative, 13 (0.9%) syngeneic twins, 5 (0.4%) HLA-matched other relatives and 4 (0.3%) unrelated. The first cord blood hematopoietic stem cell transplantation was performed in 1998 and since then there have been 14 patients that have obtained cord blood transplantations. Recently, new methods have been used like donor lymphocyte infusion (DLI) and cellular therapy. There were 111 patients with cellular therapy for post-myocardial infarction, cirrhosis, thalassemia major, multiple sclerosis, head of femur necrosis and renal cell carcinoma.
