Adsorption of Mn(ii) ions from wastewater using an AgNPs/GO/chitosan nanocomposite material.

Water contaminated with heavy metal ions is extremely poisonous and threatens living organisms. Therefore, scientists place a premium on removing heavy metal ions from water that has already been contaminated. Removing metal ions from water typically involves the use of nanomaterials.

Fe(iii) and Cr(vi) ions' removal using AgNPs/GO/chitosan nanocomposite as an adsorbent for wastewater treatment.

Heavy metal ions in water refer to significant risks to the biological system due to their high toxicity. Therefore, the decontamination of water polluted by heavy metal ions attracts significant interest of researchers. Adsorption by nanomaterials has been a widely used technique for removing heavy metal ions from water.

All-Inside Anterior Cruciate Ligament Reconstruction with Suture Tape Augmentation: Button Tie-Over Technique (BTOT).

The anterior cruciate ligament (ACL) is the most common ligamentous knee injury in pivoting sports. There are multiple techniques described for ACL reconstruction; however, still there is an ongoing debate regarding the optimal technique with minimal residual laxity and least risk of rerupture. All-inside ACL reconstruction with suture tape augmentation (InternalBrace) is a newly developed method of ACL reconstruction to help address these issues.

Outcomes of modular femoral revision implants and the effect of component design on subsidence.

Aims: Femoral revision component subsidence has been identified as predicting early failure in revision hip surgery. This comparative cohort study assessed the potential risk factors of subsidence in two commonly used femoral implant designs.

Methods: A comparative cohort study was undertaken, analyzing a consecutive series of patients following revision total hip arthroplasties using either a tapered-modular (TM) fluted titanium or a porous-coated cylindrical modular (PCM) titanium femoral component, between April 2006 and May 2018.

The Anti-fibrotic and Anti-inflammatory Potential of Bone Marrow-Derived Mesenchymal Stem Cells and Nintedanib in Bleomycin-Induced Lung Fibrosis in Rats.

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease characterized by progressive lung damage. Tyrosine kinase inhibitors are approved to treat people with IPF while bone marrow-derived mesenchymal stem cell therapy was previously suggested to inhibit pulmonary fibrosis through the alveolar epithelial cell repair. The present study aimed to evaluate the anti-inflammatory and anti-fibrotic effect of the bone marrow-derived mesenchymal stem cell (BM-MSC) therapy in comparison with nintedanib, a tyrosine kinase inhibitor, on improving survival in bleomycin-induced lung fibrosis in rats.

Lateral condylar retrograde humeral nail for management of high-energy distal humeral fractures.

Purpose: Distal metaphyseo-diaphyseal humeral fractures are challenging particularly if open, comminuted, or associated with nerve injury. In cases of open distal complex metaphyseo-diaphyseal humeral fractures inamenable for traditional methods of fixation, retrograde intramedullary locked humeral nail with a new lateral condylar point of entry has been proposed.

Methods: Two phases of study were conducted; phase I comprised computerized tomography evaluation of right humeri of 120 adult subjects, while phase II entailed prospective analysis of 18 patients who sustained firearm injuries resulting in open distal metaphyseo-diaphyseal humeral fractures associated with radial nerve injuries.

Arthroscopic Single-Tunnel Pullout Suture Fixation for Tibial Eminence Avulsion Fracture.

Various arthroscopic techniques have been devised for fixation of tibial eminence avulsions, namely percutaneous K-wires, arthroscopy-guided screw fixation, staples, TightRope (Arthrex)-suture button fixation, and transosseous suture fixation. Such techniques provide well-pronounced advantages including less postoperative pain, a reduced hospital stay, and minimal scar with resultant earlier and more compliant rehabilitation. As for transosseous suture fixation, the standard technique comprises the creation of 2 tibial tunnels exiting on both sides of the footprint of the avulsion fracture using an anterior cruciate ligament tibial guide with the angle set at 45°.

Value of urinary survivin as a diagnostic marker in bladder cancer.

Objective: To study the value of urinary survivin as a diagnostic marker for diagnosis of bladder cancer as compared to urine cytology.

Study Design: This study was carried out on 40 patients presenting with bladder cancer and 20 patients presenting with benign urological disorders.

Results: For bladder cancer diagnosis, urine cytology has lower sensitivity, accuracy, and negative predictive values as compared to survivin, while it has higher specificity and positive predictive value than survivin.

Association between dietary habits and body mass index of adolescent females in intermediate schools in Riyadh, Saudi Arabia.

Obesity among Saudi youth is a growing public health challenge. This cross-sectional study measured body mass index (BMI) and determined the eating habits and lifestyle of 107 randomly selected female adolescent students (age 12-15 years) at schools in Riyadh. The students' heights and weights were measured and a pre-tested questionnaire was used to collect data on diet and lifestyle.

Work-related health effects among wastewater treatment plants workers.

Background: Raw sewage contains various pathogenic organisms including bacteria, viruses, fungus, worms and protozoa. Workers at wastewater treatment plants (WWTPs) are exposed to these organisms as well as to H2S gas causing many health hazards.

Objective: To assess some work-related health effects among WWTPs workers with special emphasis on the most common infections as well as cardiopulmonary disorders.

Left ventricular myocardial ischemia in collagen disease associated with pulmonary hypertension: an evaluation by rest-stress gated SPECT and coronary angiography.

Objective: To detect coronary artery disease in asymptomatic patients with systemic lupus erythematosus and scleroderma associated with pulmonary hypertension, and to determine whether it is focal or diffuse ischemia.

Methods: Twenty patients with systemic lupus erythematosus (10 with pulmonary hypertension and 10 without), and 20 patients with scleroderma (10 with pulmonary hypertension and 10 without) were included in this study. Resting ECG, echocardiography, and stress-rest 99mTc sestamibi gated myocardial perfusion imaging were performed for all patients.

Serum resistin in acute myocardial infarction patients with and without diabetes mellitus.

Aim: Human resistin is an adipokine, with a possible link to coronary heart disease, and the relationship between serum resistin, insulin resistance, and type 2 diabetes mellitus (T2DM) remains controversial. Therefore, this study assessed serum resistin in patients with acute ST segment elevation myocardial infarction (STEMI), with and without T2DM.

Methods: Between June 2009 and July 2010, 55 subjects were recruited into three groups: 20 non-diabetic patients with acute STEMI (group 1), 20 diabetic patients with acute STEMI (group 2), and 15 healthy controls (group 3).

Failure of fixation of tibial plateau fractures.

Objective: To define the failure of fixation in tibial plateau fractures, detect its incidence, and determine the contributing factors.

Design: Mail survey and literature review were used to define the fixation failure; this definition was applied to a radiologic review of patients who were treated surgically for tibial plateau fracture at a Level 1 trauma unit for a three-year period from 1993 to 1995.

Patients And Setting: Forty-two consecutive patients treated surgically at our trauma unit for tibial plateau fractures were studied retrospectively, specifically for loss of fixation.

Hepatitis B virus infection among immunocompromised patients in Egypt.

Several workers reported an increased susceptibility to hepatitis B virus (HBV) in immunosuppressed patients. A study was carried out on 4 groups of supposedly immunocompromised patients for hepatitis B surface antigen (HBsAg), and anti-HBs. The 4 groups of patients were suffering from: Leprosy, Bronchial asthma, Diabetes and hepatosplenic Schistosomiasis.

Unexpected dystocia secondary to a fetal sacrococcygeal teratoma: a successful outcome.

Sacrococcygeal teratoma is a rare cause of dystocia. With recent advances in perinatal care, particularly the increasing use of maternal ultrasound, it is unlikely that unexpected dystocia secondary to this tumor will be seen by many physicians. Recent reports of this type of dystocia are rare and infant mortality secondary to it is high.
