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.

Knee osteoarthritis (KOA) is a major health problem especially in the aging population. There is a need for safe treatment that restores the cartilage and reduces the symptoms. The use of stem cells is emerging as a possible option for the moderate and severe cases. This study aimed at testing the safety of autologous bone marrow mesenchymal stem cells (BM-MSCs) expanded in vitro when given intra-articularly to patients with stage II and III KOA. As a secondary end point, the study tested the ability of these cells to relieve symptoms and restore the knee cartilage in these patients as judged by normalized knee injury and Osteoarthritis Outcome Score (KOOS) and by magnetic resonance imaging (MRI). Thirteen patients with a mean age of 50 years suffering from KOA stages II and III were given two doses of BM-MSCs 1 month apart totaling 61 × 106 ± 0.6 × 106 by intra-articular injection in a phase I prospective clinical trial. Each patient was followed for a minimum of 24 months for any adverse events and for clinical outcome using normalized KOOS. Cartilage thickness was assessed by quantitative MRI T2 at 12 months of follow-up. No severe adverse events were reported up to 24 months follow-up. Normalized KOOS improved significantly. Mean knee cartilage thickness measured by MRI improved significantly. BM-MSCs given intra-articularly are safe in knee osteoarthrosis. Despite the limited number of patients in this study, the procedure described significantly improved the KOOS and knee cartilage thickness, indicating that they may enhance the functional outcome as well as the structural component.

Purpose: Hip fracture surgery is associated with a risk of morbidity and mortality, with admission hemoglobin levels being a significant predictor of mortality risk. The aim of this study is to evaluate the relationship between the preoperative hemoglobin (Hb) levels and mortality in patients who underwent hip fracture surgeries, with the goal of enhancing prognosis prediction and reducing complications within this patient subset. In addition, to assess the characteristics of patients at a higher risk of postoperative mortality. Methods: This retrospective study was conducted at Jordan University Hospital, a single tertiary care and educational center. It included patients with hip fractures who underwent surgical repair at the Department of Orthopedic Surgery and were recruited between December 2019 and February 2022. We examined the relationships between preoperative hemoglobin status and variables such as age at admission, gender, fracture type, surgery type, comorbidities, duration of hospital stay, intensive care unit (ICU) admission, and survival outcomes. Results: We included 626 patients; the mean age was 76.27 ± 9.57 years. 3-month and 6-month mortality rates were 11.2% and 14.1%, respectively. The highest mortality was observed in patients aged over 80 years (n = 53/245, 21.6%), and in male patients (n = 53/300, 17.7%). The Hb level upon admission was lower in individuals who died within 6 months compared to those who survived (10.97 ± 2.02 vs. 11.99 ± 2.39, p < 0.001). In multivariate analysis, the independent factors that were statistically significant in the model included gender (OR = 1.867; 95% CI 1.122–3.107, p = 0.016), age (OR = 1.060; 95% CI 1.029–1.092; p < 0.001), hemoglobin level upon admission (OR = 0.827; 95% CI 0.721–0.949; p = 0.007), history of renal disease (OR = 1.958; 95% CI 1.014–3.784; p = 0.045), length of hospital stay (OR = 1.080; 95% CI 1.036–1.126; p < 0.001), and ICU admission (OR = 1.848; 95% CI 1.049–3.257; p = 0.034). Conclusion: Our study illustrates that low hemoglobin levels, history of renal disease, along with male gender, advanced age, extended hospital stays, and ICU admission were significantly associated with 6-month mortality. Future investigations should consider assessing varying degrees of anemia based on hemoglobin concentrations to provide a more comprehensive understanding of anemia’s impact on mortality. Mini- This study investigated the relationship between preoperative hemoglobin levels, patient characteristics, and mortality in patients who underwent hip fracture surgeries. The results showed that lower hemoglobin levels, history of renal disease, male gender, advanced age, extended hospital stays, and ICU admission were significant predictors for mortality.

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.

Introduction: Neck-shaft angle (NSA) is of paramount importance to orthopedic surgeons due to its implications for various pathologies of the hip and femur. The primary aim of the study was to establish if NSA measurement may be affected by imaging position (standing and supine) and provide evidence regarding whether the contralateral NSA can be used as a template. The secondary aim was to determine a reference value and precisely understand the effects of sex on NSA measurement. Materials and methods: We measured bilateral NSA in a retrospective study of 200 standing and 200 supine anteroposterior pelvis radiographs that met the inclusion criteria, while paying special attention to bilateral hip symmetry. The overall inter-rater reliability was 0.688 (CI 0.128–0.851). Matching was performed according to sex (exact matching) and age. Paired t-test, Pearson correlation coefficient, and independent sample t-test were used (p < 0.01). Results: A total of 400 pairs of femoral necks were reviewed, comprising of 200 males and 200 females. In the upright radiograph, the overall mean NSA was 131.21° ± 4.72°. There was no significant difference between right and left femur NSA among the patients (p = 0.95). On both sides, male NSA was higher than female NSA (p < 0.001). In supine radiograph, the overall mean NSA for the supine position was 133.06° ± 5.71°. There was a significant difference between NSA of the right and left femur among the patients in the supine position (p < 0.001). On supine radiographs there was no statistically significant difference between male and female NSA (p = 0.85). Conclusion: Our findings indicated no significant variability in upright radiographs between the right and left NSA. In contrast, significant asymmetry between the right and left NSA was found in the supine radiographs. However, this study does not provide definitive clinical evidence, and further clinical-oriented research is required. Level of evidence: Level III; retrospective comparative study.
