    Abstract Background: It is unknown whether the existence of severe bystander damage will affect left ventricular (LV) healing following primary percutaneous coronary intervention (PPCI). The aim of the present analysis was to follow LV recovery using 2D speckle tracking echocardiography (2-D STE) in cases with single versus multiple vessel disease with acute myocardial infarction (AMI) who underwent PPCI and to assess major adverse cardiovascular events (MACEs) within 3 months.
    Patients and methods: This work was conducted at Assiut University Heart Hospital. Of 1026 screened subjects with AMI needing PPCI and assessed for eligibility, only 89 cases fulfilled the inclusion criteria. They were classified into Group A: single vessel and Group B: multiple vessel (≥ 2 vessels) disease. Their data were obtained on admittance and after 90 days.
    Results: In group A compared to group B, there was a statistically preferable value at baseline in the global longitudinal strain- Apical 2 chamber (GLS-A2C) (-12.05 ± 3.57 vs. -10.38 ± 3.92, P = 0.039). At follow-up, the improvement was in all 2-D STE variables, including GLS-long axis (GLS-LAX) (-13.09 ± 3.84 vs.-10.75 ± 3.96, P = 0.006), GLS- apical 4 chamber (GLS-A4C) (-13.23 ± 3.51 vs.-10.62 ± 4.08, P = 0.002), GLS-A2C (-13.85 ± 3.41 vs-10.93 ± 3.97, P < 0.001) and GLS- average (GLS-AVG, P = 0.001). There was a considerable negative correlation between the recovery of LV performance and the existence of multi-vessel lesions (P = 0.009). There was no variance between the groups regarding MACEs.
    Conclusions: Patients with single vessel lesions who underwent PPCI to the culprit lesion had better recovery of LV function than those with multi-vessel (≥ 2 vessels) lesions who underwent PPCI to the culprit lesion only. The presence of multivessel involvement was an independent risk factor for deterioration in GLS.

    Abstract Background: Several interfacial surface treatments of zirconia surfaces have been proposed to improve adhesion to ceramic veneering. However, information regarding the durability and effect of such treatments on the bond strength following such treatments is lacking.
    Aim of the study: This study aimed to evaluate the shear bond strength between veneering ceramic and zirconia core after different interfacial surface treatments.
    Materials and methods: Fifty-two discs (8 mm in diameter and 3 mm in height) were fabricated from zirconia blanks using a microtome cutting machine. Zirconia discs were divided into four groups (n = 13). Group I was subjected to air-borne abrasion using (Al
    Results: The highest mean bond strength was recorded in group III (17.98 ± 2.51 MPa), followed by group II (15.10 ± 4.53 MPa), then group I 14.65 ± 2.97 MPa. The lowest mean bond strength was recorded in group IV (13.28 ± 3.55 MPa).
    Conclusions: Surface treatments had an effect on the zirconia-veneer shear bond strength. Liner coating revealed the highest shear bond strength values, significantly higher in comparison to wash firing (sprinkle technique) .

    Abstract Purpose: To provide the first meta-analysis of the impact of magnetic resonance imaging (MRI) on thoracolumbar fractures (TLFs) classification and decision-making.
    Methods: A systematic review was conducted following PRISMA guidelines. We searched PubMed, Scopus, Cochrane, and Web of Science from inception to June 30, 2023 for studies evaluating the change in TLFs classification and treatment decisions after MRI. The studies extracted key findings, objectives, and patient population. A meta-analysis was performed for the pooled frequency of change in AO fracture classification or treatment decisions from surgical to conservative or vice versa after MRI.
    Results: This meta-analysis included four studies comprising 554 patients. The pooled frequency of change in TLFs classification was 17% (95% CI 9-31%), and treatment decision was 22% (95% CI 11-40%). An upgrade from type A to type B was reported in 15.7% (95% CI 7.2-30.6%), and downgrading type B to type A in 1.2% (95% CI 0.17-8.3%). A change from conservative to surgery recommendation of 17% (95% CI 5.0-43%) was higher than a change from surgery to conservative 2% (95% CI 1-34%).
    Conclusions: MRI can significantly change the thoracolumbar classification and decision-making, primarily due to upgrading type A to type B fractures and changing from conservative to surgery, respectively. These findings suggest that MRI could change decision-making sufficiently to justify its use for TLFs. Type A subtypes, indeterminate PLC status, and spine regions might help to predict a change in TLFs' classification. However, more studies are needed to confirm the association of these variables with changes in treatment decisions to set the indications of MRI in neurologically intact patients with TLFs.

    Abstract Background: Cataract extraction surgery might modify the anterior segment characteristics. Two non-invasive devices that can identify these alterations include; Anterior Segment Optical Coherence Tomography [AS-OCT], and Ultrasound Biomicroscopy [UBM]. Aim of the work: This study aims to investigate the change of anterior chamber angle morphology before and after cataract extraction surgery by ASOCT and UBM devices.Patients and methods: Our study is a prospective randomized study. We included 100 Eyes with a significant cataract. Patients were randomized into four groups; Group A [25 eyes] with immature senile cataract, Group B [25 eyes] with intumescent cataract, Group C [25 eyes] with mature senile cataract, and Group D [25 eyes] with hyper mature senile cataract.Results: Our study included 100 patients with a mean age of 66.7 ± 10.6 years. A considerable rise was revealed in the angle measurements postoperative as compared with the preoperative measurements. We compared ASOCT and UBM results in all study groups either preoperative or postoperative and we found no statistically significant difference between ASOCT and UBM in the assessment of anterior chamber angle before and after cataract surgery [p-value > 0.05]. The mean IOP decreased from 20.58 mmHg preoperative to 16.5 mmHg postoperative.Conclusion: UBM and AS-OCT are helpful tools for imaging the anterior segment and performing the measurements required to determine the anterior chamber angle.

    Abstract Introduction: Limb amputation can cause residual limb pain (RLP) and/or phantom limb pain (PLP). Although targeted muscle reinnervation (TMR) was initially introduced to facilitate the control of prosthetic limbs, it has been noted that these patients experience less pain and improved prosthetic functional outcomes. As a result, the use of TMR in managing neuroma-related RLP is increasing. The aim of this review is to assess the quality and strength of the evidence supporting the effectiveness of TMR in managing amputation-related pain.
    Methods: Five different databases, including MEDLINE (PubMed), Scopus, Web of Science, Cochrane Library, and Embase, were searched from inception to March 2022. The protocol for this systematic review has been registered in the PROSPERO database (CRD42020218242). To be included, studies needed to compare pre- and postoperative pain outcomes or different techniques for adult patients who underwent TMR following amputation. Eligible studies also needed to use patient-reported outcome measures (PROMS) and be clinical trials or observational studies published in English. Excluded studies were case reports, case series, reviews, proof of concept studies, and conference proceedings. A meta-analysis was performed on studies that had similar intervention and control groups to examine treatment effects using a random-effects model. Studies were weighted using the inverse variance method, and a statistically significant p-value was considered to be less than or equal to 0.05.
    Results: This review included five studies for qualitative analysis and four studies for quantitative analysis. Reviewed studies enrolled a total of 127 patients. The TMR group was compared with standard treatment at 12 months follow-up. The TMR group showed significantly better PLP as assessed by the numerical rating score RLP, and PLP assessed using Patient-Reported Outcomes Measurement Information System (PROMIS) also showed significantly lower pain intensity in the TMR group.
    Conclusion: There is limited evidence of good quality favoring TMR in reducing postamputation PLP and RLP pain compared with standard care. Randomized clinical trials are encouraged to compare the efficacy of different surgical techniques.
