Mobile phones are reliable devices for communication and entertainment. However, their utilization for prolonged periods in flexed neck position is linked to neck and shoulders pain. The main purpose of this study is to investigate the association between neck pain and the duration of device use, taking into consideration gender, age, and the most frequent position in which students use their devices. Based on a self-administered online questionnaire, we filled 500 questionnaires between February 15th, 2017 and March 18th, 2017. The study sample included healthy students from health care faculties regardless of their age, gender, or handedness. Analysis of the predictors for pain severity showed that age (p = 0.04) and duration of use (p = 0.001) were significantly associated with the severity of neck pain, while only the duration of use was significantly associated with pain duration (p = 0.036). Subjects were divided into two groups according to the pain score, 75.8% had pain severity equal or less than 4/10 and 24.2% had pain severity more than 4/10. Of those with pain severity >4, 5.8% of students sought medical help at the emergency department and 12.4% visited clinics, compared to only 0.3% seeking medical advice at an emergency department and 4.2% visiting clinics in the group with pain severity of ≤4 (p4 used analgesia, compared to only 12.1% in subjects with pain severity of ≤4 (p< 0.001). This study demonstrates a significant positive correlation between the duration of mobile phone use and the duration and severity of neck pain. Furthermore, the increased severity of neck pain places a huge burden on the healthcare system.

Aim: Variations in the clinical outcomes using mesenchymal stem cells (MSCs) treatments exist, reflecting different origins and niches. To date, there is no consensus on the best source of MSCs most suitable to treat a specific disease. Methods: Total transcriptome analysis of human MSCs was performed. MSCs were isolated from two adult sources bone marrow, adipose tissue and two perinatal sources umbilical cord and placenta. Results: Each MSCs type possessed a unique expression pattern that reflects an advantage in terms of their potential therapeutic use. Advantages in immune modulation, neurogenesis and other aspects were found. Discussion: This study is a milestone for evidence-based choice of the type of MSCs used in the treatment of diseases.

Background and Aims: The relationship between intra-operative hypotension and post-operative complications has been recently studied in non-cardiac surgery. Little is known about this relationship in traumatic hip surgery. Our study aimed to investigate this relationship. Methods: A retrospective study was conducted on patients who underwent surgical correction of traumatic hip fracture between 2010 and 2015. We reviewed the perioperative blood pressure readings and the episodes of intra-operative hypotension. Hypotension was defined as ≥30% decrease in the pre-induction systolic blood pressure sustained for ≥10 min. The relationship between intra-operative hypotension and post-operative complications was evaluated. Post-operative complications were defined as new events or diseases that required post-operative treatment for 48 h. Factors studied included type of anaesthesia, blood transfusion rate, pre-operative comorbidities and delay in surgery. We used the Statistical Package for Social Sciences (SPSS, IBM 25) to perform descriptive and non-parametric statistics. Results: A total of 502 patients underwent various types of traumatic hip surgery during the study period. Intra-operative hypotension developed in 91 patients (18.1%) and 42 patients (8.4%) developed post-operative complications. Significantly more patients with hypotension developed post-operative complications compared to patients with stable vitals (18.7% vs. 6.1; P < 0.001). There was no statistically significant difference in the incidence of post-operative complication in patients receiving general or spinal anaesthesia. Pre-operative comorbidities had no significant relationship with post-operative complications. Intra-operative blood transfusion was related to both intra-operative hypotension and post-operative complications. Conclusion: There was an association between intra-operative hypotension and post-operative complications in patients undergoing traumatic hip surgery.
