Background: Treatment failure (TF) in leprosy following multidrug therapy (MDT) presents a significant challenge. The current World Health Organization (WHO) fixed-duration MDT regimen, based on lesion count, might not be adequate. Leprosy lacks clear-cut objective cure criteria, and the predictive value of post-MDT histopathological findings remains uncertain. This study aims to identify predictive factors for TF among leprosy patients who have completed the WHO-recommended MDT., Methods: An analysis was conducted on 80 individuals from a national leprosy reference center, comprising 40 TF cases (with a mean relapse at 13.0 months) and 40 controls (with a mean of 113.1 months without disease signs). Various epidemiological and clinical-laboratory parameters were assessed post-MDT., Results: In skin samples, the presence of foamy granuloma (OR = 7.36; 95%CI2.20-24.60; p = 0.0012) and histological bacillary index (hBI) ≥ 1+ (OR = 1.55; 95%CI1. 22-1.99; p = 0.0004) were significantly associated with TF, with odds ratios of 7.36 and 1.55, respectively. Individuals who experienced TF had a mean hBI of 3.02+ (SD ± 2.02), while the control group exhibited a mean hBI of 1.8+ (SD ± 1.88). An hBI ≥ 3 + showed a sensitivity of 73% and a specificity of 78% for TF detection (AUC: 0.75; p = 0.0001). Other histopathological features like epithelioid granulomas, and skin changes did not show significant associations (p > 0.05). Additionally, higher anti-phenolic glycolipid-I (anti-PGL-I) ELISA index (EI) levels were linked to a 1.4-fold increased likelihood for TF (OR = 1.4; 95%CI1.13-1.74; p = 0.0019). A mean EI of 4.48 (SD ± 2.80) was observed, with an EI ≥ 3.95 showing a sensitivity of 79% and a specificity of 59% for TF detection (AUC: 0.74; p = 0.0001). Moreover, the presence of Mycobacterium leprae (M. leprae) DNA in real-time polymerase chain reaction (qPCR) was associated with a 3.43-fold higher likelihood of TF. Multivariate regression analysis indicated that concurrent presentation of neural/perineural lymphocytic infiltrate, foamy granuloma, hBI ≥ 1+, and EI ≥ 1 markedly increased the likelihood of TF by up to 95.41%., Conclusion: Persistence of nerve-selective lymphocytic infiltrate, foamy granulomas, and bacilli in skin biopsies, and elevated EI post-MDT, may serve as predictive factors for identifying individuals at higher probability of TF., (© 2024.

Fungal infections in neonatal intensive care units (NICU) are mainly related to Candida species, with high mortality rates. They are predominantly of endogenous origin, however, cross-infection transmitted by healthcare professionals' hands has occurred. The aim of this study was to identify Candida species isolated from the hands of healthcare professionals in a NICU before and after hygiene with 70% ethanol-based gel and evaluate virulence factors DNase, phospholipase, proteinase, hemolysin, biofilm biomass production, and metabolic activity. In vitro antifungal susceptibility testing and similarity by random amplified polymorphic DNA (RAPD) were also performed. C. parapsilosis complex was the most frequent species (57.1%); all isolates presented at least one virulence factor; three isolates (Candida parapsilosis complex) were resistant to amphotericin B, two (Candida famata [currently Debaryomyces hansenii] and Candida guilliermondii [currently Meyerozyma guilliermondii]) was resistant to micafungin, and six (Candida parapsilosis complex, Candida guilliermondii [=Meyerozyma guilliermondii], Candida viswanathi, Candida catenulata [currently Diutina catenulata] and Candida lusitaniae [currently Clavispora lusitaniae]) were resistant to fluconazole. Molecular analysis by RAPD revealed two clusters of identical strains that were in the hands of distinct professionals. Candida spp. were isolated even after hygiene with 70% ethanol-based gel, highlighting the importance of stricter basic measures for hospital infection control to prevent nosocomial transmission., Competing Interests: Declaration of competing interest none., (Copyright © 2024.

Objectives: Fungal infections (FI) pose a public health concern and significantly increase mortality rates, especially within Neonatal Intensive Care Units (NICU). Thus, this study aimed to investigate epidemiological indicators, risk factors, and lethality predictors associated with FI in a NICU., Methods: This study included 1,510 neonates admitted to the NICU of a reference hospital in Brazil between 2015 and 2022. Demographic data, such as sex, birth weight, gestational age, and use of invasive devices were analyzed., Results: Thirty neonates developed invasive FI, totaling 33 episodes and an incidence of 1.2 per 1,000 patient days. Candida albicans was the most frequent species (52.9 %), the bloodstream was the most affected site (78.9 %), and 72.7 % of infections occurred between 2015 and 2018. The lethality rate associated with FI was 33.3 %, and 90 % of deaths occurred within 30 days of diagnosis of infection. Weight < 750 g, prolonged hospital stay, use of parenteral nutrition, and broad-spectrum antimicrobials were independent risk factors for infection occurrence, especially glycopeptides and 4 th generation cephalosporins, having a considerable role in the increase in fungal infections. Weight < 750 g was considered a significant predictor of lethality, and C. albicans had the highest lethality rate (40 %)., Conclusion: These findings highlight the elevated lethality rate associated with these infections, reinforcing the importance of developing strategies to control FI within NICU., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2023.

Introduction: This study aimed to evaluate the frequency of nail disorders and the presence of fungi on the nails of the hands and feet of patients with hand-foot syndrome secondary to treatment with paclitaxel., Methods: Prospective study, carried out from October 2018 to December 2019, which included 81 patients undergoing treatment for breast cancer using paclitaxel and had signs and or symptoms of hand-foot syndrome with or without nail disorders. The data were collected through interviews guided by a structured questionnaire, information from medical records and reports of mycological exams., Results: The average age of women was 54.7 ± 7.4 years. Nail disorders occurred in 69 patients (85.2%), and of these, 43 (62.3%) were positive for fungi. The fungi were yeasts ( n  = 38; 69%), dermatophytes ( n  = 15; 27.2%) and non-dermatophyte filamentous fungi ( n  = 8; 14.5%)., Conclusions: Nail disorders were the most frequent manifestations in patients with hand-foot syndrome treated with paclitaxel and occurred in 85.2% of them. It was evidenced that fungi are present on the nails of these patients and can occur in up to 65.28%. The most prevalent fungi were Candida and Trichophyton . The nail lesion was associated with the type of treatment protocol used by the patient. The results of the study point to the need to select safe management alternatives for patients, so they can prevent nail lesions and prevent the proliferation of fungi, consequently reducing negative life impact during treatment.

Objective: To identify the relationship between the Ankle Brachial Index (ABI) and the presence of cardio-metabolic diseases, alcohol, and tobacco abuse among truck drivers., Methods: This is a cross-sectional study with a quantitative approach carried out with 235 truck drivers. Demographic, professional, clinical, alcohol, and tobacco abuse data were collected through interviews. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) instrument was used for this study. An odds ratio (OR) and 95% confidence interval (95% CI) adjusted for logistic regression were used for the association between variables. The Spearman's test was used to correlate quantitative variables. The significance level used was α = 0.05., Results: The sample consisted of 235 truck drivers, all males, with an average age of 42.4 years, married (69.8%), self-reported white skin color (43.4%). ABI values equal to or less than 0.89 were identified in 38.7% of truck drivers. Tobacco abuse appeared in 18.5% of participants, and alcohol abuse was present in 8.9% of truck drivers according to the ASSIST rating. The most commonly found self-reported cardiometabolic diseases were obesity (29%), systemic arterial hypertension (SAH) (21.7%), and diabetes mellitus (DM) (10.6%). Those with altered ABI had 5.65 times the odds to have self-reported diabetes mellitus (95% CI 2.20-14.52; p = 0.0003), 2.86 times the odds to present alcohol abuse (95% CI 1.03-7.97; p = 0.0400), 3.03 times the odds to have edema (95% CI 1.25-7.36; p = 0.0144) and 5.10 times the odds to have varicose veins in the lower limbs (95% CI 2.22-11.73; p = 0.0001) compared to those with normal ABI values., Conclusion: Truck drivers have changes in the ABI which are associated with long working hours, alcohol abuse and the presence of diabetes mellitus., (Copyright © 2022.
