Background Bacterial respiratory coinfection in the setting of SARS-CoV-2 infection remains poorly described. A description of coinfection and antimicrobial usage is needed to guide ongoing antimicrobial stewardship. Objectives To assess the rate of empirical antimicrobial treatment in COVID-19 cases, assess the rate and methods of microbiological sampling, assess the rate of bacterial respiratory coinfections and evaluate the factors associated with antimicrobial therapy in this cohort. Methods Inpatients with positive SARS-CoV-2 PCR were recruited. Antibiotic prescription, choice and duration were recorded. Taking of microbiological samples (sputum culture, blood culture, urinary antigens) and culture positivity rate was also recorded. Linear regression was performed to determine factors associated with prolonged antimicrobial administration. Results A total of 117 patients were recruited; 84 (72%) were prescribed antimicrobial therapy for lower respiratory tract infections. Respiratory pathogens were identified in seven (6%) patients. The median duration of antimicrobial therapy was 7 days. C-reactive protein level, oxygen requirement and positive cultures were associated with prolonged duration of therapy. Conclusions The rate of bacterial coinfection in SARS-CoV-2 is low. Despite this, prolonged courses of antimicrobial therapy were prescribed in our cohort. We recommend active antimicrobial stewardship in COVID-19 cases to ensure appropriate antimicrobial prescribing.

In an era of antiretroviral therapy (ART) for all HIV-1-infected patients, our primary aim was to describe prevalence and characteristics of patients disengaged from care at an urban ambulatory HIV clinic. We conducted a nested case-control study. All patients who disengaged from care (defined as being lost to follow-up for at least one year) from 2007 to 2014 inclusive were identified. Cases were matched to controls in a 1:4 ratio. A total of 1250 cases were included; 250/2289 (10.9%) of patients attending our HIV clinic disengaged from 2007 to 2014. One hundred and twenty-six (50.4%) were heterosexual, 81 (32.4%) were men who have sex with men and 40 (16%) were intravenous drug users. On univariate analysis only, patients with heterosexual risk were more likely to disengage from care (50.4% vs. 33.7%, p: <0.001). Those who disengaged were younger, mean age of 39 (p: <0.001). A higher proportion of patients who disengaged from care was not receiving ART and did not have a suppressed HIV-1 viral load (p: <0.001). On multivariable analysis, Irish patients were less likely to disengage from HIV care (odds ratio: 0.567, p: 0.002). Factors associated with non-retention in HIV care have been identified. A semi-structured interview of those patients who re-engaged will take place to further examine reasons for disengagement from care.

This study reveals a large number of pregnancies in school-age girls in Baltimore. An excess frequency of premature births and child mortality was found related to mothers aged 16 or younger. The factor of prenatal care was studied in this connection, and the authors also suggest further lines of investigation.

A retrospective study of 105 barium follow-through examinations on 102 patients suspected of having malabsorption syndrome has been carried out to assess the usefulness of this technique in the diagnosis of coeliac disease. Comparison with histological and biochemical data has been made. Of the 34 examinations on 31 patients with a proven diagnosis of coeliac disease, 30 examinations showed both abnormal X-ray and biopsy findings, two examinations showed normal X-ray appearance but abnormal jejunal biopsy and two showed normal jejunal histology but abnormal X-ray findings. There were two cases with sensitivity, non-invasive nature, ease and cheapness of the technique, barium follow-through examination is suggested as the initial investigation in patients suspected of coeliac disease.
