This study aimed to compare the radiologic parameters of both feet in patients with unilateral accessory navicular bone (ANB) and evaluate the differences from one another. Forty-one patients with unilateral ANB volunteered to participate in this study from August 2019 to January 2020. Patient data, including age, sex, body mass index (BMI), type of ANB, and presence of symptoms were obtained. Group 1 comprised 23 patients with asymptomatic unilateral ANB, and group 2 comprised 18 patients with symptomatic unilateral ANB. Seven radiologic parameters were evaluated assessing hindfoot, midfoot, and forefoot alignment-calcaneal pitch angle, talocalcaneal angle, tibiocalcaneal angle, naviculocuboid overlap (NCO), talonavicular coverage angle (TNCA), anteroposterior talo-first metatarsal angle, and lateral talo-first metatarsal angle. The mean age of patients was 40.1 years in group 1 and 42.6 years in group 2. Mean BMI was 25.2 in group 1 and 26.6 in group 2. No significant differences were noted in the radiologic parameters between the ANB and contralateral sides in all patients. The radiologic parameters of both feet in symptomatic and asymptomatic patients were not significantly different. No significant differences were noted between the affected sides of type 1 and 2 ANB and contralateral sides in terms of the radiologic parameters. BMI was significantly correlated with NCO and TNCA. This study demonstrated that the presence of an accessory navicular bone did not affect radiologic parameters of the foot. Radiologic parameters of both feet in symptomatic patients were not significantly different.

Materials & methods We performed in silico comparative genome analysis of Sporothrix species using ab initio tools and in-house scripts. We predicted genes and repeats, compared genomes based on synteny, identified orthologous clusters, assessed genes family expansion/contraction, predicted secretory proteins and finally searched for similar sequences from various databases. Results The phylogenomics revealed that Sporothrix species are closely related to Ophiostoma species. The gene family evolutionary analysis revealed the expansion of genes related to virulence (CFEM domain, iron acquisition genes, lysin motif domain), stress response (Su[var]3-9, Enhancer-of-zeste and Trithorax domain and Domain of unknown function 1996), proteases (aspartic protease, x-pro dipeptidyl-peptidase), cell wall composition associated genes (chitin deacetylase, chitinase) and transporters (major facilitator superfamily transporter, oligo-peptide transporter family) in Sporothrix species. Conclusion The present study documents the putative pathogenic/virulence-associated genes in the Sporothrix species.Aim To standardize MALDI-TOF-MS based identification and antifungal susceptibility (AFST) for yeasts directly from automated blood cultures to reduce turnaround time. Materials & methods Direct-ID after lysis-centrifugation (0.5% SDS) standardized in 40 and validated in 250 yeast positive samples. Direct-AFST was standardized with fluconazole (28 samples) and evaluated (70 samples) for seven antifungals. Results Direct-ID had a high sensitivity (97.2%) and specificity (94.3%). Correct species-level identification showed 100% in C. tropicalis, C. krusei, C. parapsilosis. Direct-AFST had a 100% categorical agreement with culture-AFST for posaconazole, anidulafungin and >90% categorical agreement for amphotericin B, voriconazole and fluconazole. Conclusion Direct-ID and subsequent direct-AFST is a rapid and robust method to reduce the turnaround time for the diagnosis of invasive candidiasis.Background PEGylation technology is one of long-acting delivery (LAD) platforms used to increase half-life of protein therapeutics. N-Ethylmaleimide However, PEGylation of anti-Factor D Fab (PEG-aFD) poses challenges for detecting anti-drug antibody (ADA) to both Fab and polyethylene glycol (PEG) portions. Results Although the bridging ELISA using traditional assay diluent containing Tween 20 is good for detecting ADA to Fab, it failed to detect ADA to PEG. Instead of only reducing Tween 20 in assay diluent, using a proprietary commercial buffer PEG50-1 as assay diluent successfully enabled the detection of ADA to both Fab and PEG with fit-for-purpose sensitivity and drug tolerance. Conclusion Identification of appropriate assay diluent is critical for detection of ADA to both Fab and PEG in a PEGylated molecule.RT-PCR-based assays for the detection of SARS-CoV-2 have played an essential role in the current COVID-19 pandemic. However, the sample collection and test reagents are in short supply, primarily due to supply chain issues. Thus, to eliminate testing constraints, we have optimized three key process variables RNA extraction and RT-PCR reactions, different sample types and media to facilitate SARS-CoV-2 testing. By performing various validation and bridging studies, we have shown that various sample types such as nasopharyngeal swab, bronchioalveolar lavage and saliva, collected using conventional nasopharyngeal swabs, ESwab or 3D-printed swabs and, preserved in viral transport media, universal transport media, 0.9% sodium chloride or Amies media are compatible with RT-PCR assay for COVID-19. Besides, the reduction of PCR reagents by up to fourfold also produces reliable results.Aim The study aimed to investigate and compare the predictive capacity of a systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) to determine a hemodynamically significant coronary artery stenosis assessed by fractional flow reserve (FFR). Patients & methods A total of 207 chronic coronary syndrome patients with FFR measurement were enrolled in the study. NLR, PLR and SII levels were calculated. Results The cut-off value of the SII (620) was associated with 78.4% sensitivity and 64.0% specificity to predict a hemodynamically significant stenosis. SII level independently predicted FFR ≤0.80. Conclusion SII is an independent predictor of functionally significant coronary stenosis detected by FFR in chronic coronary syndrome patients. SII levels can predict hemodynamically severe obstruction better than NLR and PLR.
