Update on the Use of Mesenchymal Stem Cells and their Products in Hematopoietic Stem Cell Transplantation
Graft Versus Host Disease (GVHD) is a major limitation to the success of allogeneic Hematopoietic Stem Cell Transplantation (HSCT) as Steroid-Refractory (SR) acute GVHD carries poor prognosis due to the absence of an efficacious second-line therapy. Mesenchymal Stem Cells (MSCs) which have immunosuppressive, immunomodulatory, and regenerative properties may become a highly effective therapeutic modality for SR-GVHD in the near future. MSCs have already been approved to treat childhood SR-GVHD in Japan, and they have been conditionally licensed in New Zealand and Canada. It is expected that MSCs will be approved for the treatment of SR-GVHD in adults in Europe, North America, and other parts of the world within a few years. Utilization of the recently introduced techniques including the use of MSC products such as exosomes and Extracellular Vesicles (ECVs) instead of the parent MSCs, robotic manufacturing technology, and genetic engineering of MSCs will ultimately overcome the remaining obstacles facing the widespread utilization of MSCs and their products as therapeutics not only in HSCT but also in other medical fields. The aim of this review is to provide an update on the remarkable progress achieved in the use of MSCs and their products in the field of HSCT
A Rare Coexistence: Breast Cancer, Pheochromocytoma and Von Recklinghausen Disease
Breast cancer associated with type-1 neurofibromatosis is a rare clinical entity. These patients have a higher risk of developing various types of cancers, especially tumors derived from the embryogenic neural crest, such as pheochromocytoma. This publication aims to add to the literature a rare association between Type-1 Neurofibromatosis, breast cancer, and pheochromocytoma.We present a rare case of a 51-year-old Tunisian woman with neurofibromatosis who was diagnosed with breast cancer and pheochromocytoma. The breast tumor was classified as T4b N1M0, and the discovery of the pheochromocytoma was incidental to thoracic-abdominal-pelvic CT. She underwent surgery to remove the adrenal gland and was referred to medical oncologists to receive chemotherapy for her breast cancer. Type-1 Neurofibromatosis disorder is a benign disease but can expose patients to numerous neoplasms. The challenging diagnosis at an early stage can worsen the prognosis and make medical care more difficult
Recommendations for Measurement of Bodybuilding Internal Training Load by eTRIMP Method
Currently, analysis of training data metrics has become increasingly important in characterizing high throughput. In fact, in bodybuilding, the RPE (rate of perceived exertion) assessment is the metric commonly used to calculate training volume. Therefore, this study demonstrates another way for bodybuilding athletes to evaluate their training through heart rate using the TRIMP (training impulse) method proposed by Edwards to analyze the intensity of a given training model. For this athlete, it is important to stay most of the time outside heart rate zone 1, not have more than 10% of total training time in zone 5 and contain the largest proportion of total training time in zones 2, 3 and 4
Investigation of Malpractice Claims Concerning Orthopedic Surgeons in Sari, North of Iran, 2015-2020
Introduction: Treatment failure and claims against physicians may have many negative consequences. Orthopedic surgeons have always been among the most used specialists. Therefore, the investigation of causes and the process of these claims can help reduce the negative effects of medical malpractice on physicians and society.Materials and methods: This retrospective study investigated all medical orthopedic negligence cases in Sari, Iran, from March 2015 to March 2020. Data were collected using a researcher-made checklist and analyzed in SPSS software (V-21).Results: Out of 57 finalized cases investigated in this study, surgeons were found liable in 23 (40%) cases. The mean ± SD age of patients was 41 ± 19.3. Moreover, the level of education had a positive correlation with the surgeon’s liability. The most common cause of complaint was reduced Range of motion (ROM) and the most common type of complained surgery was “open reduction & internal fixation” (ORIF). None of the surgeons were found liable due to surgical site infection or device failure. The mean ± SD time for the file processing was 11.1 ± 10.1 months. The mean indemnity payment was 320 million Iranian Rials (9.7% of indemnity for death in Iran).Conclusion: The most effective way to reduce medical complaint cases is to increase the knowledge and skill levels of physicians. The lack of a blinded arbitration system in both organizations could lead to bias in the case assessment process. Moreover, considering the long processing time of the claims, it is recommended that new technologies should be used to reduce the time and increase the accuracy of the final verdict. The absence of a ‘no-fault’ compensation program is a significant flaw in Iran violating patients’ rights. Also, more studies are needed to evaluate justice and equality in Iranian medical commissions
Does change in cervical dilation after anesthesia impact latency after cerclage placement?
Background: Pregnant individuals with early cervical dilation have a high risk for preterm birth. The authors encountered cases where cervical dilation increased after anesthesia administration for a cerclage. Objective: The primary objective was to assess if a change in cervical dilation after anesthesia administration for a cerclage was associated with a shorter latency to delivery. Study design: This was a retrospective chart review of pregnancies from January 1, 2011, to December 31, 2021, who had a cerclage and delivered at our institution. Maternal demographics, obstetrical history, operative details, and delivery information were collected. Multi-fetal gestations, un-indicated cerclages, and abdominal cerclages were excluded. The primary outcome was the difference in cervical dilation between the office and the operating room after spinal anesthesia administration. A multivariable regression was performed. Results: A total of 183 pregnancies were included. The mean gestational age at cerclage placement was 18 weeks (STDEV 3.6). Twenty-nine percent of patients (53/183) were more dilated in the operating room compared to the office The latency between cerclage and delivery was not different if there was a cervical change between these settings (p = 0.655). There was an increased risk for preterm delivery with dilation in the office (OR 1.01, CI 1.01 to 2.5), but not with dilation in the operating room (OR 1.4, CI 0.9 to 2.0). Conclusion: Cervical dilation between the office and the operating room is different. Pregnancies with more dilation delivered at earlier gestations. However, a change in dilation between the office and the operating room was not associated with a shorter latency. 
Research Progress of BTG2 as a Tumor Prognostic Factor
Cancer is a major public health issue and the main cause of death worldwide. Despite improvements in diagnostic techniques and treatment methods, cancer still seriously affects the quality of life of patients, which cause serious social and economic burdens. Therefore, there is an urgent need to identify potential biomarkers to improve diagnosis, treatment, and prognosis of cancer. BTG2 is a cell proliferation suppressor gene that serves as a tumor suppressor gene in the occurrence and development of various tumors. Many studies have shown that BTG2 can serve as a prognostic marker in various tumors. So, fully tap the potentials of BTG2 as a tumor prognostic marker will bring more possibilities to provide a new method or new diagnostic and therapeutic tool for treating cancer

Cancer is a disease that implies several different genotypic and phenotypic traits in its whole process of development: tumorigenesis
Management and use of vacuum systems in a surgery ward
Vacuum therapy has become a new option in the treatment of wounds in surgery. More recently this therapy has also been used as a treatment for anastomotic leakages in association or not to emergency surgery. The management of these devices should be familiar to all the staff in a surgical ward
Effectiveness of levocetirizine in treating allergic rhinitis while retaining work efficiency
The manifestation and severity of Allergic rhinitis symptoms show diurnal variation which negatively impacts the patient’s quality of life, day-to-day activities, and productivity at the workplace. The symptoms worsen at night or early morning and therefore administration of levocetirizine towards evening may be more acceptable. Consequently, the present study evaluated the effectiveness of evening Levocetirizine administration on 24-hour symptom control, Physical and mental health, and daytime somnolence in patients with allergic rhinitis the study was a prospective, open-labeled, single-arm, two-center, observational study among patients with allergic rhinitis. Levocetirizine was prescribed as 5 mg or 10 mg once a day evening oral dose for at least 7 days before sleep. The 24-hour total nasal symptom scores (TNSS) for self-reported signs and symptoms of allergic rhinitis were recorded. Additionally, study evaluations included the SF-12 scale (Quality of Life), Stanford Sleepiness Scale (degree of sleepiness), and work productivity and activity impairment (WPAI) questionnaires. These evaluations were performed at baseline (Day 0) and at scheduled intervals of Day 1 (24-hour), Day 3, and Day 7. Results demonstrated that evening administration of Levocetirizine facilitates 24-hour symptom control while having no significant effect on daytime somnolence, daily activities, and the work productivity of patients
Considering antioxidant supplements as a means to prevent diseases
Oxidative stress has been implicated in Alzheimer’s and many other diseases and more recently, it has been linked to various COVID-19-related symptoms. Many diseases do not develop immediately as a result of the accumulated causes or injury, but rather, as a result of prolonged exposure to elevated oxidative stress, which disrupts the body’s natural homeostatic functions
