Traditional vs. modified Ringer lactate-based del Nido cardioplegia impacts on clinical outcomes in patients undergoing coronary artery bypass grafting: Results from a prospective, randomized, blinded trial.

Introduction: Myocardial protection with cardioplegia is a crucial approach to mitigate myocardial damage during coronary bypass grafting surgery (CABG) with cardiopulmonary bypass (CPB). The major component of the del Nido cardioplegia solution, Plasma-Lyte A, is difficult to obtain in Iran due to high cost. The objective of the current study was to study if the lactated Ringer's solution as the base for del Nido solution (LR DN) usage is a viable option as a substitute for Plasma-Lyte A in adult patients presenting for CABG surgery.

Routine antibiotic prophylaxis and early implant failure: is there a link?

Data Sources: A systematic search was conducted across multiple databases (PubMed via MEDLINE, Cochrane Library, and Web of Science) up to October 1st, 2023. Manual screening of reference lists was performed, alongside searches in clinical trial registries to ensure comprehensive coverage.

Study Selection: Only randomized controlled trials (RCTs) that compared antibiotic prophylaxis with no antibiotics or placebo in systemically healthy individuals undergoing dental implant surgery were included.

Long-term survival of Astra Tech vs Straumann dental implants and restorations.

Design: This randomized controlled trial (RCT) compared the survival and complications rates between two well-established implant systems, namely AST (OsseoSpeed TX 3.0-5.0 S, TX 4.

The homeostasis and therapeutic applications of innate and adaptive immune cells in periodontitis.

Objectives: Periodontitis (PD) is one of the most common dental disorders. This chronic oral inflammation is caused by complicated interrelations between bacterial infections, dysregulated immune reactions, and environmental risk factors. A dysregulated immune response can lead to inflammatory bone resorption by allowing the recruitment of pro-inflammatory immune cells to the periodontal tissues.

The association between end-tidal carbon dioxide and arterial partial pressure of carbon dioxide after cardiopulmonary bypass pumping in cyanotic children.

Evidence suggests the high capability of non-invasive assessment of the End-tidal carbondioxide (ETCO2) in predicting changes in arterial carbon dioxide pressure (PCO2) following major surgeries in children. We aimed to compare EtCO2 values measured by capnography with mainstream device and EtCO2 values assessed by arterial blood gas analysis before and after cardiopulmonary bypass pumping in cyanotic children. This cross-sectional study was performed on 32 children aged less than 12 years with ASA II suffering cyanotic heart diseases and undergoing elective cardiopulmonary bypass pumping.

Electrochemical Nanolithography on Silicon: An Easy and Scalable Method to Control Pore Formation at the Nanoscale.

Lithography on a sub-100 nm scale is beyond the diffraction limits of standard optical lithography but is nonetheless a key step in many modern technological applications. At this length scale, there are several possible approaches that require either the preliminary surface deposition of materials or the use of expensive and time-consuming techniques. In our approach, we demonstrate a simple process, easily scalable to large surfaces, where the surface patterning that controls pore formation on highly doped silicon wafers is obtained by an electrochemical process.

Effect of Opium Addiction on Postoperative Arrhythmia Among Patients Undergoing CABG operation on Cardiopulmonary Bypass.

Objectives: Postoperative arrhythmia is an important complication of coronary artery bypass grafting (CABG) surgeries among patients. It seems that opioid usage is implicated in the pathogenesis of this condition due to its impacts on different organ systems, such as the autonomic nervous system. The present study was performed to investigate the effect of opium use on postoperative arrhythmia in patients undergoing CABG surgery.

Serum levels of interleukin-6, interleukin-8, interleukin-10, and tumor necrosis factor-α, renal function biochemical parameters and clinical outcomes in pediatric cardiopulmonary bypass surgery.

Background: Cardiopulmonary bypass causes detrimental effects on remote organs due to inflammatory response. One of these organs is kidney that is frequently affected by cardiac surgery. Acute kidney injury is a post-cardiopulmonary bypass complication, which may result in increased post-operative morbidity and mortality.

Oral Dexmedetomidine Versus Midazolam as Anesthetic Premedication in Children Undergoing Congenital Heart Surgery.

Background: Premedication is required for reducing anxiety and child's struggling against mask acceptance on anesthesia in pediatric surgery for congenital heart disease. Midazolam has been widely used for this purpose, but because of its side effects, finding an effective replacement with less complication is necessary.

Objectives: In the present study, we compared the efficacy of oral midazolam versus dexmedetomidine in terms of anxiolysis and mask acceptance behavior.

Premedication with oral pregabalin for the prevention of acute postsurgical pain in coronary artery bypass surgery.

Background: For coronary artery bypass grafting (CABG) sternotomy should be performed. The pain after surgery is severe and requires medical intervention. Use of the analgesics is limited by their side effects and studies suggest that prevention with some medications before surgery is effective in controlling the postoperative pain.

HA/nylon 6,6 porous scaffolds fabricated by salt-leaching/solvent casting technique: effect of nano-sized filler content on scaffold properties.

Nanohydroxyapatite (n-HA)/nylon 6,6 composite scaffolds were produced by means of the salt-leaching/solvent casting technique. NaCl with a distinct range size was used with the aim of optimizing the pore network. Composite powders with different n-HA contents (40%, 60%) for scaffold fabrication were synthesized and tested.

Primary brain hydatosis.

The authors present a case of intracranial hydatid cyst presented with severe headache, nausea and vomiting. Radiological investigations, including CT scan and MRI revealed a solitary cyst in the right temporal lobe, paraventricular area. Total excision of the cyst was done.
