Synthesis, characterization, DFT calculations and biological activity of new Schiff base complexes.

Schiff bases ligand (HL) was produced by condensing 4-aminobenzohydrazide with N-(4-chlorophenyl)-2-(4-formylphenoxy)acetamide. Cobalt (II), nickel (II), and copper (II) acetate and ligand are reacted to form 1:1 complexes. By using electronic spectra, magnetic susceptibility measurements, infrared data from 1H NMR, and XRD studies, the ligand and its metal complexes have been characterized. According to the spectrum data, the ligand functions as a monobasic bidentate, coordinating with the nitrogen atom of azomethine (-C[bond, double bond]N-) group and the oxygen atom of carbonyl group in enol form. An octahedral structure has been proposed for Co(II), Ni(II), and Cu(II) complexes according to magnetic and electronic spectrum analysis. Using the DFT method, the computational investigations of the ligand and its metal complexes showed the bond lengths, bond angles, and quantum chemical parameters. To determine the thermal stability and mode of thermal degradation of hydrazone ligand and its complexes, thermogravimetric analysis was approved out on the samples. Two calculated method, Horowitz-Metzger and Coats-Redfern, were used to calculate the characteristics of the composites' thermal degradation mechanisms at each step, including their breakdown kinetics. The ligand and its complexes were investigated for their cytotoxicity in vitro compared to human amnion (WISH) and epitheliod carcinoma (Hela). The Ni(II) complex showed highly inhibition against (WISH) growth (IC50 = 18.28±1.8 µM) with relationship to the produced chemicals and other common medications. The interaction between the ligand and its complexes with the genetic tumor (3hb5) receptor was examined using docking experiments.

Basidiobolomycosis Mimicking Fistulizing Crohn's Disease: A Case Report From Saudi Arabia.

Gastrointestinal basidiobolomycosis (GIB) is a rare, emerging fungal infection caused by Basidiobolus ranarum, which requires a high index of clinical suspicion for early diagnosis and management. It is prevalent in hot and humid regions, and its clinical manifestations may mimic inflammatory bowel disease (IBD), malignancy, and tuberculosis (TB). This often results in the disease being missed or incorrectly diagnosed. We present the case of a 58-year-old female patient from the southern region of Saudi Arabia who presented with persistent non-bloody diarrhea for four weeks and was found to have GIB. This condition is associated with significant morbidity and mortality if not diagnosed and treated in a timely manner. The optimal therapeutic strategy for managing this rare infection has not yet been established. Most patients described in the literature have received a combination of pharmaceutical and surgical therapy. Including GIB in the differential diagnosis of gastrointestinal disorders that do not fit the diagnosis may help with its early diagnosis and management.

Reiter's syndrome following intravesical Bacillus Calmette-Guerin therapy for bladder carcinoma: Case report.

Reiter syndrome is an autoimmune condition that develops in as a reactive response to GI or GU related infectious and rarely related to Intravesical BCG. it is a triad of conjunctivitis, urethritis, and arthritis. Here we report the case of a female patient who developed acute Reiter's syndrome following intravesical Bacillus Calmette-Guerin (BCG) immunotherapy for superficial bladder cancer. After the sixth dose in the maintenance phase of treatment the patient developed conjunctivitis, aseptic urethritis, and polyarthritis consistent with a diagnosis of Reiter's syndrome. In this patient non-steroidal anti-inflammatory drugs (NSAIDs), oral steroids and anti-tuberculosis drugs were administered with complete resolution of symptoms.

Left ventricular function outcome after coronary artery bypass grafting, King Abdullah Medical City (KAMC)- single-center experience.

BACKGROUND: Coronary artery bypass grafting is known to be associated with better outcome in ischemic heart disease patients with low ejection fraction. We aim to demonstrate the effect of coronary artery bypass grafting (CABG) on left ventricle (LV) systolic function and to identify the predictors that adversely lead to postoperative poor outcome. RESULT: This is a cross-sectional prospective study; we included 110 patients with left ventricular ejection fraction (LVEF) < 50% who underwent CABG with a mean age of 56.1 ± 12.2 years old. Those patients were classified into two groups: group I, 76 (69%) patients with LVEF > 35%, and group II, 34 (31%) patients with LVEF < 35%. Our results as regards demographic and clinical data revealed that group II patients had a significantly higher prevalence of diabetes mellitus (DM) and Euro SCORE II compared to group I patients (p = 0.05 and < 0.001 respectively); otherwise, all other clinical predictors did not differ between the two studied groups. There was a significant improvement in LVEF post-surgery (p = 0.05) in both groups with observed no significant difference recorded for in-hospital mortality rate among patients with different groups. DM, significant diastolic dysfunction, and insertion of IABP are predictors of in-hospital mortality of the patients (p = 0.001, 0.03 and < 0.001, respectively) CONCLUSION: We concluded that there is a significant improvement of LV systolic function after CABG and hence better survival rate. DM, significant diastolic dysfunction, and perioperative insertion of IABP are predictors of mortality after cardiac surgery. Special care should be provided to such patients to improve their outcome.
