Despite group A streptococci being an infrequent cause of pharyngitis in adult outpatients, sore throat remains a common indication for antibiotic prescription. This prospective multicentre non-randomised study describes a community pharmacy-based antimicrobial stewardship intervention consisting in the implementation of rapid antigen testing (RAT) for the management of adults with sore throat. Trained pharmacists triaged patients presenting with symptoms of pharyngitis using the modified Centor score. Those at risk for streptococcal infection were tested with RAT...

Fusobacterium necrophorum (Fn), a gram-negative anaerobe, is increasingly implicated as an etiologic agent in older adolescents and young adults with sore throat. Inadequately treated Fn pharyngitis may result in suppurative complications such as peritonsillar abscess and Lemierre's syndrome. Data from the literature suggest that the incidence of life-threating complications in these age groups from Fn pharyngitis (Lemierre's syndrome) in the United States exceeds those associated with group A beta-hemolytic streptococcal (GAS) pharyngitis (acute rheumatic fever)...

Antimicrobial resistance has been one of the biggest global current issues in medicine and public health. Overuse and imprudent use of antimicrobial agents are recognized as one of the leading causes of antibiotic resistance. The aim of this study was to analyze the attitudes of Polish physicians practicing at the community level towards antibiotics and antimicrobial resistance. The majority of physicians taking part in the survey believed that Polish people overuse antibiotics (98%). Most physicians (91%) considered that antimicrobial resistance is a major problem at present...

The title compound, C31 H48 O6 , is a polyoxygenated ep-oxy steroid obtained by a multi-step synthesis involving oxidation of 7-de-hydro-cholesterol. It crystallizes in the P 21 21 21 space group; however, the absolute structure of the molecule in the crystal could not be determined by resonant scattering. The configuration at the C5 and C6 positions is in both cases of the α-type, as is that of the C atoms of the ep-oxy ring. Mol-ecules in the crystal form chains parallel to the b axis by hydrogen bonding between O-H donors and carbonyl O-atom acceptors...

Introduction: Both non-Group A streptococcal (non-GAS) pharyngitis and Group A streptococcal (GAS) pharyngitis are commonly found in patients with sore throat. It is not known whether or not they present with similar signs and symptoms compared to patients with non-streptococcal pharyngitis. Methods: MEDLINE was searched for prospective studies that reported throat culture for both GAS and non-GAS as a reference standard, and reported at least one sign, symptom, or the Centor score...

The increased use of antibiotics for acute tonsillitis is a public health problem. 80% of the antibiotic prescriptions for acute tonsillitis are done in the Primary Care practice (PCP). The inappropriate use of the antibiotic causes bacterial resistance and treatment failure. Only patients with acute tonsillitis caused by Group A beta-hemolytic streptococcus (GAS) have benefit of the antibiotic treatment, which is a predict cause in 5-20%. In order to assess the antibiotic prescribing for acute tonsillitis by the doctors in the PCP in Macedonia we use the data from the national project about antibiotic prescribing for acute respiratory tract infections which was conducted in November 2014 during a period of 4 weeks as part of the E-quality program sponsored by the IPCRG...

The title compound, C22H34O6, is one of the products obtained by oxidation of squalene with the catalytic system RuO4(cat.)/NaIO4. It crystallizes in the P-1 space group, with four crystallographically independent mol-ecules related by a pseudo-C2 symmetry axis. The structural analysis also shows that the title compound is isomeric with two products previously reported in the literature and that are obtained by the same reaction procedure. In particular, out of the seven chiral C atoms present in the mol-ecule, the title compound shows the opposite configuration at, respectively, four and two chiral centres with respect to the isomeric compounds...

This article outlines the journey of behavioral sciences education from a multidisciplinary array of topics to a discipline with a name, core identity, and mission in dental schools' curricula. While not exhaustive, it covers pivotal events from the time of the Gies report in 1926 to the present. Strengths and weaknesses of current behavioral sciences instruction in dental schools are discussed, along with identification of future opportunities and potential threats. Suggestions for future directions for behavioral sciences and new roles for behavioral sciences faculty in dental schools are proposed...

We previously defined teaching domains necessary for successful inpatient medicine attending rounds from the trainees' perspective in Role Modeling, Learning Environment, Teaching Process and Team Management. We sought to understand whether trainee characteristics and daily fluctuations in workload influence the prioritization of these domains. We conducted a prospective observational study in general medicine inpatient wards at a university, Veterans Affairs, and a county hospital affiliated with one academic institution over the course of 6 months...

The title compound, C22H34O6, is a product of oxidation of squalene with the catalytic system RuO4(cat.)/NaIO4. The asymmetric unit contains two crystallographically independent mol-ecules of very similar geometry approximately related by the non-crystallographic translation vector c/2. As a consequence, the average diffracted intensity in the hkl layers with odd l is systematically lower than in the layers with even l. In one mol-ecule, the lactone ring and part of the adjacent tetra-hydro-furan ring are disordered over two orientations with refined occupancy ratio of 0...

Acute sore throat is a common presentation in primary care settings. We aimed to improve our compliance with national antibiotic guidelines for sore throat symptoms to 90% in 3 months' time period. The national guidelines are based on Centor criteria. A retrospective audit of 102 patient records with sore throat symptoms presenting between 1 January to 30 December 2015 showed that over 50% were given antibiotics. Those who were prescribed antibiotics, 27% did not meet NICE criteria and 85% of patients were given immediate antibiotic prescription...

Fine control of the tautomeric forms of [1,2,4]triazolo[3,2-c][1,2,4]triazole derivatives in acidic conditions has been achieved by acting on the electronic character of the substituent at position 7 of the heterobicycle and on the counterion. Strong electron releasing or electron withdrawing substituents lead almost exclusively to a single tautomeric form, the 1H-3H or the 2H-3H, respectively. In the case of the phenol substituent, both tautomeric forms are present in comparable amount in solution; the two tautomers can also be selectively precipitated in different crystalline salts using suitable counterions...

Group A Streptococci (GAS) are the main causative agents of bacterial pharyngitis, which require antibiotic therapy. Rapid diagnostic tests detecting GAS combined with Centor/McIsaac score enable accurate differential diagnosis (viral vs. bacterial) and prompt commencement of targeted treatment. The aim of this study was to assess the specificity, sensitivity, PPV and NPV of QuikRead go® Strep A (Orion Diagnostica Oy, Finland) recommended for the detection of GAS in pharyngeal swabs. Quick diagnostic test results were compared with physical examination findings, Centor/McIsaac score and results of reference testing (conventional microbial cultures)...

This paper reports that the bulk polymerization of l-aspartic acid diethyl ester catalyzed by immobilized CAL-B at 80 °C for 24 h gives primarily (∼95%) α-linked poly(l-aspartate) in 70% yield with DPavg = 50 and regioselectivity (α/β) = 94 : 6. Plots of log{[M]0 /[M]t } vs. time and DPavg vs. conversion indicate that this polymerization proceeds in a controlled manner by a chain-growth mechanism up to 90% conversion. Thereafter, competition occurs between chain growth and step mechanisms.

The title compound, C12H20N4O5, crystallizes in the monoclinic space group P21, with four crystallographically independent mol-ecules in the asymmetric unit. The four mol-ecules have a very similar conformation that is basically determined by the formation of two intra-molecular hydrogen bonds between the amino NH2 donors and the carbonyl and ring O-atom acceptors, forming, respectively, R(6) and R(7) ring motifs.. In the crystal, inter-molecular hydrogen bonding leads to the formation of R2(2)(10) ring patterns, involving one amide CONH2 donor and an imidazole N-atom acceptor...
