Shrunken pore syndrome (SPS) is a condition that manifests itself as the decreased renal clearance of low-molecular-weight proteins but normal clearance of creatinine. Pregnant women with evidence of SPS during the first trimester have an increased risk of developing preeclampsia (PE). The nitric oxide (NO) metabolism markers arginine and ADMA, especially their ratio (Arg/ADMA), are recognized markers of endothelial dysfunction. The aim of this nested case-control study was to establish first-trimester reference intervals (RI) for markers of NO metabolism and to study these markers in women with evidence of SPS at the end of the first trimester...

Nontuberculous mycobacteria (NTM) cause severe opportunistic infections and have a rising incidence in most settings. Rising diagnostic need must be met by national reference laboratories, which rely on Clinical & Laboratory Standards Institute (CLSI) guideline approved manual readout of microtiter plates for antimicrobial susceptibility testing (AST) to determine antibiotic minimum inhibitory concentrations (MICs). Interpretation of these plates leads to different outcomes between laboratories. The SensiTitre™ Vizion™ Digital MIC Viewing System (Vizion) offers a more streamlined approach using semi-automated reading...

The CDC recommended outpatient treatment of pelvic inflammatory disease (PID) is an intramuscular dose of ceftriaxone plus 14 days of doxycycline, with or without metronidazole. European guidelines (2017) include moxifloxacin plus ceftriaxone as a first line regimen, particularly for women with Mycoplasma genitalium-associated PID. However, the susceptibility of bacteria recovered from the endometrium of women with PID to moxifloxacin is unknown. The in vitro antibiotic susceptibility of facultative and anaerobic bacteria recovered from endometrial biopsy samples were evaluated from 105 women having symptomatic PID and/or histologically confirmed endometritis...
