BACKGROUND A graduating medical doctor is expected to be competent in physical examinations across all systems. The exploration of how gender affects the development of clinical skills has not been explored in an Arab context, despite cultural restrictions that make it more difficult for students and doctors to examine the opposite sex. METHODS A cross sectional survey was undertaken of graduating final year medical students in Northern Jordan. We asked about students' perceptions regarding factors that may impact the development of clinical skills potentially related to gender, and asked about the frequency of examinations performed during their training for intimate and general physical examinations on all patients, as well as patients of the opposite sex. We also asked about the students' confidence in performing the examinations (3-point Likert-scale). Comparison of male and female proportions was done using Chi square tests analysis. RESULTS One hundred eighty-eight final year students from 481 students ntimate clinical examinations at all. CONCLUSIONS In our context, clinical exposure to both intimate and general clinical examinations differs significantly between male and female students. A greater awareness and more research on the influence of gender on clinical skill attainment in conservative cultures is needed with appropriate adaption of clinical teaching. TRIAL REGISTRATION Non interventional thus not required.BACKGROUND Tendon-bone interface healing and ligamentization of the graft in anterior cruciate ligament (ACL) reconstruction with autografts are important factors affecting treatment outcome. This study aimed to investigate the effectiveness of a cylindrical titanium-web (TW) in tendon-bone interface healing and graft maturation in ACL reconstruction. METHODS Fourteen mature female CLAWN miniature swine underwent bilateral ACL reconstructions with patellar tendon (PT) autografts. In one limb, the TW/tendon complex was placed into the proximal side of the tibial tunnel. Only the graft was transplanted into the tunnel in the control limb. The proximal side of the graft was sutured into the stump of the native ACL and the distal end was stapled to the tibia. The animals were euthanized at 4 and 15 weeks postoperatively, for histological and biochemical analyses. AZD-5462 RESULTS Microscopic images in TW limbs showed that ingrowth of tendon-like tissue and mineralized bone tissue into the TW connected the bone and the tendon directly. In contrast, fibrous tissue intervened between the bone and tendon in the control limbs. The total amount of collagen cross-links (which defines the strength of collagen fibers) and the maturation of collagen cross-links in TW tendons were significantly higher (p  less then  0.05) than those of control limbs. There was no significant difference in the ratio of dihydroxy-lysinonorleucine to hydroxy-lysinonorleucine (an indicator of tissue specific collagen maturation) between TW tendons and that of the native PT. CONCLUSIONS TW promoted the maturation and formation of collagen cross-links in the grafted tendon while maintaining the cross-links pattern of native tendon collagen, and enabled direct binding of tendon to bone.BACKGROUND Associations between serum phosphorus level and the incidence of ischemic stroke are not clear. This study aimed to measure serum phosphorus, vitamin D3, and uric acid levels in ischemic stroke patients compared to a population without ischemic stroke. METHODS In this cross-sectional study, 133 patients admitted to a neurology ward with the diagnosis of ischemic stroke were compared with a control group comprising 133 age- and gender-matching individuals. The presence of ischemic stroke was confirmed by a neurologist based on clinical signs, symptoms, brain CT scan, and MRI. Blood samples were taken from all patients in the first 24 h of admission to measure serum phosphorus, vitamin D3, calcium, and uric acid levels. RESULTS According to the results of this study, uric acid medians in patients with stroke and controls were 4.9 [3.8-6.4] and 3.9 [3.5-4.9] mg/dL, respectively (p  less then  0.001). Median phosphorus and vitamin D levels were significantly lower in stroke patients than the controls (3.6 [3.02-4.21] vs. 4.2 [3.8-4.6]) and (15.1 [8.2-27.9] vs. 22.7 [10.4-39.2]), respectively. Multiple logistic regression analysis showed that the ischemic stroke was positively associated with the vitamin D level and negatively correlated with the uric acid level. The phosphorus level was not significantly predictive of ischemic stroke. CONCLUSION Lower serum levels of vitamin D3 and higher levels of uric acid were associated with ischemic stroke. There are still unknowns about the role of these indicators on ischemic stroke and it requires further studies.BACKGROUND The purse-string suture has been widely used for bleeding control after percutaneous interventions through arteriovenous fistula (AVF) and graft (AVG), and it requires suture removal the next day. This study aimed to introduce a simple method using a tourniquet to facilitate hemostasis following AVF or AVG sheath removal after percutaneous procedures. METHODS Data were retrospectively collected and included all the consecutive patients who received bleeding control with a tourniquet after percutaneous AVF or AVG interventions. Hemostasis was facilitated using the tourniquet technique after sheath removal. RESULTS A total of 1966 patients who received the tourniquet technique for bleeding control after percutaneous AVF or AVG interventions were included. Bleeding control was successfully achieved in all patients. Regarding complications, hematoma, thrombosis, and rebleeding occurred in 57 (2.9%), 11 (0.6%), and 8 (0.4%) patients, respectively. Neither pseudoaneurysm nor infection occurred in the patients. Age, gender, pre-existing diseases (including diabetes and hypertension), procedure count, sheath size, hemodialysis access type, and canalization route were similar between patients with and without complications. The primary patency rates at 6,12, 24, and 36 months were 85.0, 64.6, 53.8, and 41.6%, respectively. CONCLUSIONS The tourniquet technique is an effective and safe approach for facilitating hemostasis after catheter-based percutaneous interventions of hemodialysis accesses.
