(Benz)imidazo[1,2-a]quinolinium Salts: Access via Unprecedented Regiospecific non-AAIPEX Strategy and Study of Their Tunable Properties.

An unprecedented non-AAIPEX protocol has been developed to access diverse monosubstituted cationic polycyclic heteroaromatic compounds (cPHACs) from the readily available azolium salts and phenacyl bromides via Ru(II)-catalyzed tandem annulation cum aromatization. This atom-economic protocol executes a range of intermediate steps e. g. double C-H activation, nucleophilic addition, annulation, and dehydration cum aromatization in one-pot manner under the generation of H2O as the sole byproduct. Moreover, the systematic tunability of photo-physical and electrochemical properties of these new class of cPHACs can be authenticated from the DFT calculated frontier molecular orbital energies that might be beneficial for their potential applications in optoelectronics and DNA intercalation.

Evaluation of a rapid, chip-based, micro-PCR assay for detection of rabies virus in human and canine specimens.

Rabies, a lethal zoonotic encephalitis, remains a significant global health concern, causing an estimated 60 000 annual fatalities worldwide. Dogs serve as the primary reservoirs and vectors for transmitting this infection to humans. Definitive diagnosis of rabies in both human and animal cases necessitates laboratory testing involving various clinical specimens. However, the complexity of laboratory infrastructure and the need for skilled personnel, along with the challenge of maintaining cold-chain integrity during sample referral, hinder the decentralization of diagnostic facilities. This study aimed to assess the efficacy of the Truenat rabies assay, a rapid, portable, semiautomated, and closed PCR-based system, for the diagnosis of rabies in both humans and animals. The Truenat assay demonstrated a sensitivity of 100% and a specificity of 86.96% when compared with the fluorescent antibody test (FAT), as the reference standard, on 147 canine brain samples tested. Notably, the Truenat assay exhibited a sensitivity and specificity of 100% when tested on 48 human brain specimens. Furthermore, an examination of 148 human antemortem samples (cerebrospinal fluid, saliva, and skin biopsy) using both the Truenat assay and a validated real-time reverse transcriptase PCR assay revealed a κ value of 0.505, indicative of a moderate level of agreement between the two tests. Thus, the Truenat assay offers a robust, reliable, and affordable point-of-care solution to enhance rabies diagnostic capacity in endemic areas.

Base-catalyzed Effective C2-Amidation of Azolium Salts Using Isocyanates under Mild Conditions.

An unprecedented base-catalyzed hydroarylation of isocyanates with azolium salts was developed, which follows a simple reaction pathway and provided facile access to diverse C2-amidated azolium salts under mild conditions. Importantly, this methodology can also be applied for the successive C2-amidation of a bisimidazolium salt with two different isocyanates to provide the corresponding unsymmetrically substituted bisamide derivatives. Notably, the obtained amidated salts can also serve as a prominent carbene surrogate for the synthesis of metal-NHC complexes.

Assessment of Knowledge, Attitudes, and Practices Regarding Menstrual Hygiene Management Among Adolescent Schoolgirls (10-19 Years) in the Saurashtra Region, Gujarat.

Background Menstrual health management proves pivotal for the adoption of hygienic practices and the embracement of womanhood from the onset of menarche. Menstrual hygiene is pivotal yet under-addressed among adolescent girls in India. This study aimed to assess the knowledge, attitudes, and practices regarding menstrual hygiene and influencing factors. Methodology A cross-sectional study was conducted among 361 adolescent schoolgirls aged 10-19 years in the Saurashtra region of Gujarat using a pretested questionnaire. Multistage sampling was used. In the first stage, six schools (three rural and three urban) were selected through random sampling. In the second stage, all adolescent girls aged 10-19 years in the selected schools who had attained menarche were invited to participate. Those who provided written assent were included in the study. The data were analyzed with descriptive statistics and logistic regression. A p-value <0.05 was considered significant. Results Knowledge about menstruation was evenly distributed as good (47.65%) and poor (52.35%). Most relied on mothers for information and considered menstruation a normal phenomenon. Attitudes reflected complex cultural perceptions. The use of sanitary pads was high (96.12%), although 39.89% used reused absorbents. Multivariate analysis revealed age 16-19 years (adjusted odds ratio (AOR) = 2.08, 95% confidence interval (CI) = 1.14-3.81), higher parental education, pit latrine usage (AOR = 6.7, 95% CI = 2.97-15.15), and knowledge about menstruation (AOR = 8.21, 95% CI = 4.56-14.78) as positive predictors of good menstrual practices. Conclusions Despite the widespread use of sanitary pads, the persisting knowledge gap and sociocultural influences lead to unhygienic practices. Improving awareness and attitudes through educational interventions among adolescent girls and mothers, in particular, addressing cultural taboos through the engagement of all stakeholders, and improving sanitation infrastructure in schools are imperative.

Exophiala dermatitidis as a cause of central line associated bloodstream infection in an infant: Case report and literature review.

BACKGROUND: Exophiala dermatitidis is a dematiaceous fungus known to cause superficial, subcutaneous, cutaneous and deep seated infections, and rarely central line associated bloodstream infection (CLABSI). A case of CLABSI due to E. dermatitidis in an infant is described. CASE REPORT: Clinical and laboratory data were extracted from patient's chart and laboratory records. The isolate was identified as E. dermatitidis by phenotypic characterization and sequencing of the ITS and LSU regions of the ribosomal DNA. Medline search was done to review all cases of CLABSI due to E. dermatitidis. Among the azoles tested, posaconazole (0.06mg/l), voriconazole (0.03mg/l) and itraconazole (0.03mg/l) showed very low MICs when compared to fluconazole (4mg/l) CONCLUSIONS: As we did not found in the literature any case of CLABSI due to E. dermatitidis in an infant, we report the first one. Sequencing is a mandatory method for accurately identifying this species. Prompt removal of the central line, followed by a treatment with amphotericin B or an azole, seems to be the most effective treatment.
