This work is development of new hydantoin molecules as treatment of potential antibacterial and antifungal activity against clinical pathogens causing infectious disease. Synthesized compounds were evaluated in molecular docking studies, the most effective compound is used to dock against the targets of 1U1Z, and 1AI9 kinases, to evaluate its binding affinity, hoping to rationalize and obtain potent of antibacterial, antifungal agents.
The FTIR,
H &
C NMR, and mass spectra were used to conform new molecules and their evaluation of antimicrobial activity. Gram-negative bacteria of Pseudomonas aeruginosa (ATCC-27853), Klebsiella pneumoniae (recultured) and Escherichia coli (ATCC-25922), and gram-positive bacteria of Enterococcus faecalis (recultured) and Staphylococcus aureus (ATCC-25923) were evaluated for all compounds. The in vitro antifungal activity was evaluated against Cryptococcus neoformans (recultured), Candida albicans (recultured), Aspergillus niger, Microsporum audouinii (recultured) andfloxacin (-8.2 kcal/mol) in 1U1Z protein and the compound 3b was highest binding affinity (-8.8 kcal/mol) than clotrimazole (-6.8 kcal/mol) in 1AI9 protein respectively.
A novel set of imidazolidine-2,4-dione compounds 3a-h have synthesized and characterized successfully. The screening of antimicrobial activity shows that all compounds possess antimicrobial activities. In addition, the objective of the study was succeeded with a few of the promising molecules, which are proving to be a potential treatment of bacterial infection candidates.

Respiratory tract infections (RTIs) are important health problems with high incidence and consequent economic costs. The study aimed to analyze trajectories of experienced RTI symptoms and use of healthcare and antibiotics.
The study adopted a cross-sectional design and face-face interview using a structured questionnaire. The questionnaire comprised a) social demographics; b) last episode of symptomatic RTIs; c) responses to the RTIs; d) antibiotics obtained from clinics and medicine shops for the RTIs. The study subjects were residents in randomly selected villages in Anhui, China. The study settings were the residents households. Descriptive analyses were conducted to draw symptoms trajectory and identify relationship between healthcare seeking and symptoms and common sociodemographic variables.
A total 91.1% (1968) of 2160 eligible residents completed the interview who reported 1.83 episodes of RTIs in the pass year on average. learn more Over half (54.8%) of these RTI episodes had led to visit to clinics for r manage shared decision- making around antibiotic treatment.
RTIs incur a large volume of healthcare-seeking and antibiotics use and there is an urgent need for effective education measures on proper service especially antibiotics use. Patients' reported RTI symptoms manifest peculiar trajectories and their retrospective recall of the course of prior RTI episodes and associated actions may guide their future responses to similar infections. Knowledge of these may help inform doctors about patient expectations, enabling them better manage shared decision- making around antibiotic treatment.Prosthetic joint infection (PJI) is a common complication of the knee and hip arthroplasty and represents a huge challenge for physicians. PJI raises serious social, economic and clinical concerns in the public health that need a comprehensive approach to better focus on proven strategies for disease prevention and treatment. History and clinical signs on joint site are useful means for suspecting PJI that need to be confirmed through major and minor diagnostic criteria. The pathogen isolation and the resulting antibiogram are crucial to guide the correct antibiotic strategy and together with surgical treatment (prosthesis revision and spacer implantation) represent the cornerstones to eradicate the infection before attempting a new arthroplasty. External fixator with removal of the spacer may be an option before performing a new arthroplasty when the infection does not heal. Arthrodesis may also be considered if the arthroplasty is contraindicated. Limb amputation is the last chance when pathogen eradication failed and might lead to life-threatening situations.
Primary intestinal lymphomas (PILs) are rare, and this study compared the clinical outcomes of aggressive primary intestinal B-cell lymphomas (aB-PILs) and T/natural killer-cell lymphomas (T/NK-PILs).
The clinical information of patients diagnosed with aggressive PILs at our institution between 1995 and 2015 were retrospectively investigated. Pathological subtypes were confirmed according to the 2016 revision of the World Health Organization classification. The correlation between clinicopathological features and overall survival (OS) was determined using univariate and multivariate analyses.
Cases of T/NK-PILs had higher initial bowel perforation incidence (67% vs. 7%, P<0.001) and lower complete response rate to first-line chemotherapy regimens (22% vs. 69%, P=0.009) than aB-PILs. Patients with aB-PILs had a better 5-year event-free survival rate (55.8% vs. 13.9%, P=0.026) and a 5-year OS rate (74.3% vs. 29.6%, P=0.036) than those with T/NK-cell lymphomas. Multivariate analysis identified that female gender and stage III/IV were unfavorable prognostic factors. Among the 54 patients with diffuse large B-cell lymphoma (DLBCL), those with International Prognostic Index (IPI) scores of 0-2 had a better 5-year OS rate than those with scores of 3-5 (84.2% vs. 46.8%, P=0.002). IPI scores of 3-5 (P=0.026) and tumors located in the large intestine (P=0.015) were poor prognostic factors based on the multivariate analysis.
The prognosis of T/NK-PILs was less favorable than that of aB-PILs. Female gender, stage III/IV disease, DLBCL with IPI scores of 3-5, or tumors in the large intestine were poor prognostic factors.
