Abstract Skiing and snowboarding are popular competitive recreational sports that can be associated with significant injury. Previous studies of skiing injuries have been conducted, but evaluating injury types patterns over long periods time needed to drive effective prevention efforts. We hypothesized would differ among snowboarders skiers the number remained constant time. This is a retrospective study patients presenting or United States emergency departments from 2000 2019. A total...

Purpose Urine dipstick analysis (UDA) is a useful tool in clinical practices. Abnormalities UDA parameters have been observed as result of extreme exercise. The exact incidence abnormalities, particularly proteinuria, the running ultramarathons unknown. purpose this study was to estimate proteinuria and identify characteristics those with proteinuria.Methods We conducted prospective observational using urine samples from volunteer athletes before immediately after Leadville Trail 100 Run...

Infections is yet one of the life-threatening complications hematopoietic stem cell transplantation (HSCT). The myeloablative and immunosuppressive conditioning regimens, which are administered before HSCT, dampen defense capacity recipients' immune systems. In this condition, opportunistic infections, especially viral infections such as cytomegalovirus (CMV) can be reactivated cause morbidity mortality in HSCT patients. Here, we aimed to find out any possible relationship between types...

Marine seaweeds are a famous type of traditional food containing various kinds secondary metabolites. These organisms have different biological activities such as antitumor, antiviral, and antioxidant. The aim this study was to investigate the effects total extract Sargassum glaucescens on neuropathy pain induced by paclitaxel in mice.S. collected from Persian Gulf. seaweed extracted maceration with methanol-ethyl acetate (1:1) solvent. effect analyzed. All results were analyzed one-way...

The incidence of acute kidney injury (AKI) associated with ultramarathon running is varied partially because onsite measurement serum creatinine concentration (Cr) rarely performed at races due to logistical challenges. We conducted a prospective observational study using blood samples from volunteer athletes before and immediately after the Leadville Trail 100 Run in August 2014. goals our were determine those meeting AKI criteria following race evaluate utility medical equations...

Exercise-associated hyponatremia (EAH) is a well-known condition among endurance athletes at low altitudes. The incidence of EAH during ultramarathons high altitudes warrants further investigation. This prospective observational study was conducted on the participants Leadville Trail 100 run, 161- km race held altitude (2,800 m-3,840 m).Venous blood samples were collected before and immediately after race. completed an electronic survey Our main outcome measure post-race serum sodium ([Na+])...

Background: In many medical studies, patients may experience various events. The analysis in such studies is often administrated using multi-state models. current study aimed to investigate the effect of risk factors and transition probability on recurrence death with breast cancer. Materials Methods: This was a retrospective cohort 814 women cancer admitted Shahid Ramezanzadeh Radiotherapy Center Yazd province Iran between years 2004 -2012 were followed until 2016. A model applied for data...

Background Currently, almost all patients with probable abdominal injury undergo urinalysis in emergency department (ED). The present survey was conducted the aim of assessing diagnostic values compare computed tomography (CT) scan contrast for predicting possible intra-abdominal injuries children affected by blunt trauma. Materials and Methods: accuracy study accomplished on patients' < 16-year-old trauma who were admitted to (ED) underwent both CT scan. Demographic baseline characteristics...

Acute lymphoblastic leukemia (ALL) is the most common cause of cancer-related fatality among children. This study aimed to identify significant prognostic factors for incidence pediatric ALL. retrospective study, conducted from 2007 2016 in Iranian city Mashhad, enrolled 417 patients with The diagnosis was confirmed by Giemsa staining bone marrow smears. first recurrence regarded as event interest and non-relapse mortality competing through a three-parameter Gompertz model. level statistical...

Background: We designed this study to assess the significant prognostic factors of both recurrence and death in patients with acute lymphoblastic leukemia a university-based hospital using parametric competing risks model. Methods: In retrospective study, we included 417 leukemia. Staining bone marrow smears Giemsa method confirmed diagnosis, justifying at least 25% lymphoblast. Treatment was based on Berlin-Frankfurt-Munster (BFM) protocol. considered first cancer as event interest...

Background: Chronic Kidney Disease (CKD) is a disease in which the kidney’s functionality declines gradually. The aim of this study was to identify significant laboratory prognostic factors on death due CKD clinical complex. Materials and Methods: A retrospective including 109 patients with end-stage renal treated at Iran Helal pharmaceutical complex conducted between 2014-2018. survival time set as interval starting dialysis until CKD. Also, transplantation considered competing risk,...

Introduction: Hodgkin lymphoma (HL) is an uncommon cancer of lymphocytes, characterized by cancerous Reed-Sternberg cells in inflammatory background. HL exceptionally curable disease with combination chemotherapy, radiotherapy, or combined modality treatment. This analysis aimed to identify significant prognostic factors on the cure rate. Materials and Methods: The medical records 110 patients hospitalized from 2007 up 2014 18 months follow-up was retrospectively reviewed Taleghani hospital...

PURPOSE: Skiing and snowboarding are popular competitive recreational sports, but could potentially be associated with significant injury. In 2014/15, there were 53.6 million ski snowboarder visits to United States (US) resorts. Previous studies of skiing injuries have been conducted, evaluating injury patterns over long periods time needed drive effective prevention efforts. The purpose this study is compare presenting emergency departments (EDs) a 20-year period. METHODS: This was...

Autologous hematopoietic stem cell transplantation (auto-HSCT) has become an effective treatment for a wide range of hematologic and non-hematologic diseases. Patients undergoing HSCT might require multiple platelets red blood (RBC) transfusions during aplasia phase until engraftment, which could profoundly affect patients' conditions. Identification risk factors associated with product requirements help in decreasing transfusion-related complications. We evaluated the association disease...

Introduction: Recurrent event data are common in many longitudinal studies. Often, a terminating such as death can be correlated with the recurrent process. A shared frailty model applied to account for association between and terminal events. In some situations, fraction of subjects experience neither events nor death; these cured. Methods: this paper, we discussed Bayesian approach joint presence cure fraction. We compared estimates parameters Frequentist approaches via simulation studies...

The observations of repeated or recurrent events occur in many longitudinal studies. Furthermore, sometimes there may exist a terminal event such as death, which is strongly correlated with events. In situations, fraction subjects who will never experience the interest during long follow-up period considered to be cured. this article, we proposed joint frailty model presence cure fraction. dependency modeled by shared that contained both andterminal hazard functions. It allows estimate two...

Introduction: The present study compares the diagnostic accuracy of urinalysis with computed tomography (CT) scan in pediatrics blunt abdominal trauma. The aim this was comparing value and CT contrast, as gold standard, for predicting probable organ injury these patients. Methods: The done on children trauma aged less than 16 years who were presented to emergency department both had been them. Demographic data, mechanism, results urinalysis, ultrasonography regarding organs recorded. To...
