9%) and 199/1342 (14.8%) developed UTI and 46/551 (8.3%) and 81/1342 (6.0%) developed pyelonephritis, respectively. Adjusted HRs of 100 mg versus 50 mg were 1.01 (95% CI 0.78-1.30) on first UTI, 1.37 (95% CI 0.95-1.98) on first pyelonephritis episode, 1.82 (95% CI 1.20-2.74) on first consultation for cough, 2.68 for dyspnoea (95% CI 1.11-6.45) and 2.43 for nausea (95% CI 1.03-5.74).

Daily prophylaxis for recurrent UTI with 100 mg instead of 50 mg nitrofurantoin was associated with an equivalent hazard on UTI or pyelonephritis, and a higher hazard on cough, dyspnoea and nausea. We recommend 50 mg nitrofurantoin as daily prophylaxis.

Routine microbiology results are a valuable source of antimicrobial resistance (AMR) surveillance data in low- and middle-income countries (LMICs) as well as in high-income countries. Different approaches and strategies are used to generate AMR surveillance data.

We aimed to review strategies for AMR surveillance using routine microbiology results in LMICs and to highlight areas that need support to generate high-quality AMR data.

We searched PubMed for papers that used routine microbiology to describe the epidemiology of AMR and drug-resistant infections in LMICs. We also included papers that, from our perspective, were critical in highlighting the biases and challenges or employed specific strategies to overcome these in reporting AMR surveillance in LMICs.

Topics covered included strategies of identifying AMR cases (including case-finding based on isolates from routine diagnostic specimens and case-based surveillance of clinical syndromes), of collecting data (including cohort, point-prevalence surality in LMICs.
The various AMR surveillance strategies warrant a thorough understanding of their limitations and potential biases to ensure maximum utilization and interpretation of local routine microbiology data across time and space. For instance, surveillance using case-finding based on results from clinical diagnostic specimens is relatively easy to implement and sustain in LMIC settings, but the estimates of incidence and proportion of AMR is at risk of biases due to underuse of microbiology. Case-based surveillance of clinical syndromes generates informative statistics that can be translated to clinical practices but needs financial and technical support as well as locally tailored trainings to sustain. Innovative AMR surveillance strategies that can easily be implemented and sustained with minimal costs will be useful for improving AMR data availability and quality in LMICs.
To compare serum β-D-glucan (BDG) levels in candidaemia with different Candida species, especially C.auris.

Aga Khan University clinical laboratory database was retrospectively reviewed from January 2015 to December 2019. Blood culture positive cases with any Candida species and concomitant BDG level were included.

Among the 192 cases included in our study, 48 were C.albicans, 54 C.auris, eight C.glabrata, 32 C.parapsilosis, 43 C.tropicalis and seven other Candida species. The level of BDG was significantly lower in C.auris (median 62.43, interquartile range (IQR) 12.80-182.94 pg/mL) compared to C.albicans (median 266.83, IQR 66.29-523.43 pg/mL) and C.tropicalis (median 324.41, IQR 105.20-523.44 pg/mL). The sensitivity of serum BDG was significantly lower for C.auris (43.75%, 95% CI 29.5-58.8%) than C.tropicalis (79.07%, 95% CI 64.0-90.0%).

Serum BDG has lower sensitivity in patients with suspected C.auris candidaemia in our setting. Considering that C.auris has higher morbidity and mortality than other species, a more sensitive test is required.
Serum BDG has lower sensitivity in patients with suspected C. auris candidaemia in our setting. Considering that C. auris has higher morbidity and mortality than other species, a more sensitive test is required.
Bacillus cereus is responsible for food poisoning and rare but severe clinical infections. The pathogenicity of strains varies from harmless to lethal strains. However, there are currently no markers, either alone or in combination, to differentiate pathogenic from non-pathogenic strains. The objective of the study was to identify new genetic biomarkers to differentiate non-pathogenic from clinically relevant B.cereus strains.

A first set of 15 B.cereus strains were compared by RNAseq. A logistic regression model with lasso penalty was applied to define combination of genes whose expression was associated with strain pathogenicity. The identified markers were checked for their presence/absence in a collection of 95 B.cereus strains with varying pathogenic potential (food-borne outbreaks, clinical and non-pathogenic). Receiver operating characteristic area under the curve (AUC) analysis was used to determine the combination of biomarkers, which best differentiate between the "disease" versus "non-disease" groups.

Seven genes were identified during the RNAseq analysis with a prediction to differentiate between pathogenic and non-pathogenic strains. The validation of the presence/absence of these genes in a larger collection of strains coupled with AUC prediction showed that a combination of four biomarkers was sufficient to accurately discern clinical strains from harmless strains, with an AUC of 0.955, sensitivity of 0.9 and specificity of 0.86.

These new findings help in the understanding of B.cereus pathogenic potential and complexity and may provide tools for a better assessment of the risks associated with B.cereus contamination to improve patient health and food safety.

To assess the prevalence of and factors associated with post-coronavirus disease 2019 (COVID-19) syndrome 6months after the onset.

A bidirectional prospective study. selleck inhibitor Interviews investigated symptoms potentially associated with COVID-19 6months after the disease onset of all consecutive adult inpatients and outpatients with COVID-19 attending Udine Hospital (Italy) from March to May 2020. IgG antibodies against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) were also evaluated 6months after the onset of symptoms, at the time of the interview.

A total of 599 individuals were included (320 female, 53.4%; mean age 53years, SD 15.8) and interviewed 187days (22 SD) after onset. The prevalence of post-COVID-19 syndrome was 40.2% (241/599). The presence of IgG antibodies was significantly associated with the occurrence of post-COVID-19 syndrome (OR 2.56, 95% CI 1.48-4.38, p 0.001) and median SARS-CoV-2 IgG titres were significantly higher in patients with post-COVID-19 syndrome than in patients without symptoms (42.
