    Abstract Background: In South Africa (SA), a client-initiated partner notification (PN) approach is implemented for the management of sexual partners of patients presenting with sexually transmitted infections (STIs) or STI syndromes.
    Objectives: To explore the demographic, sexual behavioural and clinical characteristics associated with PN intentions among symptomatic STI service attendees at sentinel primary healthcare facilities in three SA provinces.
    Methods: We analysed cross-sectional data obtained from 1 293 adults enrolled into STI aetiological surveillance during 2019 - 2020 in Gauteng, KwaZulu-Natal and Western Cape provinces. Self-reported sexual practices, PN intentions and clinical data were collected using nurse-administrated questionnaires. We assessed gender-stratified factors associated with the index case's willingness to notify their sexual partners of their STI syndrome diagnosis. Univariable and multivariable Poisson regression models with robust error variance were used to determine factors associated with gender-stratified PN intentions.
    Results: The enrolled participants comprised 887 male (68.6%) and 406 female (31.4%) STI clients. Self-reported PN intentions were higher among women than men (83.5% v. 64.4%; p<0.001). Multivariable analyses revealed that casual sex partnerships during the preceding 3-month period and enrolment at the KwaZulu-Natal site were independent barriers to PN intent among male participants. For females, enrolment at the Gauteng site was independently associated with lower PN intentions, while presenting with genital ulcer syndrome was a motivator towards PN intent. The primary reasons cited for non-disclosure across both genders were casual sexual encounters, followed by geographically distant partnerships and fear of disclosure.
    Conclusion: We show that demographic and behavioural characteristics, as well as relationship dynamics, may influence the PN intentions of STI service attendees in SA. Alternative PN strategies should be considered, based on the reported barriers, to increase overall STI notification, strengthen partner management and ultimately reduce STI incidence.

    Abstract Objective: As key stakeholders in educational settings, teachers' awareness on Urinary Tract Infections (UTI) will ultimately enhance its management in schools and community. This study aimed to assess the level of knowledge, attitudes, and practices (KAP) on UTIs among teachers in Sri Lanka.
    Materials and methods: Conveniently selected 373 school teachers were assessed using a pre-tested questionnaire. Each of the individual was scored and categorized as either satisfactory or poor. Descriptive statistics and chi-square tests were performed to describe the outcomes.
    Results: Around 80% of respondents demonstrated awareness regarding the microbial origin of UTIs, while 42% possessed knowledge of women's increased susceptibility to UTIs. Over 90% of participants had favorable attitudes toward drinking adequate amounts of water, personal hygiene, and consulting doctors for UTI symptoms. Each inquiry demonstrated significant disparities between individuals with satisfactory and poor attitudes (
    Conclusions: The study revealed satisfactory levels of awareness and favorable attitudes among respondents on UTIs. However, there is a further need for increased awareness, specifically regarding the risk factors associated with UTIs.

    Abstract In recent years, lignocellulosic biomass has become an attractive low-cost raw material for microbial bioprocesses aiming the production of biofuels and other valuable chemicals. However, these feedstocks require preliminary pretreatments to increase their utilization by microorganisms, which may lead to the formation of various compounds (acetic acid, formic acid, furfural, 5-hydroxymethylfurfural, p-coumaric acid, vanillin, or benzoic acid) with antimicrobial activity. Batch cultures in microplate wells demonstrated the ability of Yarrowia strains (three of Y. lipolytica and one of Y. divulgata) to grow in media containing each one of these compounds. Cellular growth of Yarrowia lipolytica W29 and NCYC 2904 (chosen strains) was proven in Erlenmeyer flasks and bioreactor experiments where an accumulation of intracellular lipids was also observed in culture medium mimicking lignocellulosic biomass hydrolysate containing glucose, xylose, acetic acid, formic acid, furfural, and 5-HMF. Lipid contents of 35% (w/w) and 42% (w/w) were obtained in bioreactor batch cultures with Y. lipolytica W29 and NCYC 2904, respectively, showing the potential of this oleaginous yeast to use lignocellulosic biomass hydrolysates as feedstock for obtaining valuable compounds, such as microbial lipids that have many industrial applications. KEY POINTS: • Yarrowia strains tolerate compounds found in lignocellulosic biomass hydrolysate • Y. lipolytica consumed compounds found in lignocellulosic biomass hydrolysate • 42% (w/w) of microbial lipids was attained in bioreactor batch cultures.

    Abstract Objective: Identify and analyze the role of nursing professionals in the development and care of adolescent health in Honduras, by analyzing the curricular content of the training provided to nursing students with respect to adolescent health, and by studying policies on adolescent health.
    Methods: Mixed methods study, with a sequential explanatory approach, carried out from May to July 2023 through surveys of nursing schools, analysis of policy documents, a survey with nursing professionals, and a focus group. Quantitative data were analyzed using descriptive statistics and qualitative data, applying the theoretical framework of Walt and Gilson.
    Results: During the research, 18 documents were analyzed and seven nursing schools, 141 nurses, and 10 key actors in leadership positions participated. The results point to the need to update and disseminate the regulatory framework, ensure the necessary resources and structure to implement sustainable intersectoral programs, and train professionals. Schools are an important space for the implementation of actions; in this context, the adoption of school nursing programs could be beneficial. Nurses were identified as key figures in program implementation and should be taken into consideration when developing policies aimed at adolescents.
    Conclusions: Nurses participate in various stages of the policy implementation process and can make important contributions to school health at the first level of care. To this end, it is necessary to increase the capacities of nurses and nursing educators in relation to current and relevant issues in adolescent care.

    Abstract An optical fiber pH sensor based on a long-period fiber grating (LPFG) is reported. Two oppositely charged polymers, polyethylenimine (PEI) and polyacrylic acid (PAA), were alternately deposited on the sensing structure through a layer-by-layer (LbL) electrostatic self-assembly technique. Since the polymers are pH sensitive, their refractive index (RI) varies when the pH of the solution changes due to swelling/deswelling phenomena. The fabricated multilayer coating retained a similar property, enabling its use in pH-sensing applications. The pH of the PAA dipping solution was tuned so that a coated LPFG achieved a pH sensitivity of (6.3 ± 0.2) nm/pH in the 5.92-9.23 pH range. Only two bilayers of PEI/PAA were used as an overlay, which reduces the fabrication time and increases the reproducibility of the sensor, and its reversibility and repeatability were demonstrated by tracking the resonance band position throughout multiple cycles between different pH solutions. With simulation work and experimental results from a low-finesse Fabry-Perot (FP) cavity on a fiber tip, the coating properties were estimated. When saturated at low pH, it has a thickness of 200 nm and 1.53 ± 0.01 RI, expanding up to 310 nm with a 1.35 ± 0.01 RI at higher pH values, mostly due to the structural changes in the PAA.

    Abstract Background and aims: Primary biliary cholangitis (PBC) is an immune-mediated liver disease. The immunological profile seems to relate to clinical prognosis. This study aims to determine the role of autoantibodies in the course of liver disease and in the response to ursodeoxycholic acid.
    Methods: Between January 2016 and December 2020, 143 patients with PBC who underwent immunological liver profile evaluation were enrolled. All data were extracted retrospectively from electronic clinical records. Chi-square test, Fisher's exact test and Mann-Whitney test were used to evaluate the relationship between autoantibodies and biochemical parameters, clinical outcomes and therapeutic response scores. A significance level of 0.05 was used.
    Results: Antimitochondrial antibodies were present in 91.6%, antiglycoprotein-210 antibody (anti-gp210) in 18.2% and anti-Sp100 in 19.6% of patients. The incidence of liver-related death was higher in patients with autoimmune hepatitis variants. The occurrence of cirrhosis or portal hypertension was not linked to the presence of any of the autoantibodies tested. No relationship was found with the probability of dying or being transplanted. Patients with anti-Sp100 antibodies had higher baseline levels of aspartate aminotransferase and alanine aminotransferase and lower immunoglobulin M levels. Patients with anti-gp210 were more likely to have a lower median transplant-free survival rate and higher median risk of liver transplant or liver-related death using the GLOBE and UK-PBC scores.
    Conclusion: Our findings confirm a strong association between anti-gp210 antibodies and a worse outcome. The association between anti-Sp100 and hepatic lesions requires further elucidation.

    Abstract This is a reflective study aiming to analyze the implementation of Advanced Practice Nursing (APN) and provide perspectives regarding the role of these professionals in the Region of the Americas, particularly in Brazil. Several countries in the world have introduced advanced nursing roles to improve quality of care and reduce health care costs. However, these roles have not been fully implemented in Latin American countries, although some countries have held advanced discussions about it and proposed graduated courses. Brazil fulfills all conditions necessary for the implementation of the education of advanced practice nurses. The investment in advanced practice nurses will result in positive outcomes for the health of the population in a short period of time, with lower costs for governments than other possible actions. It is also a strategic way to address the persistent pressure on health services, whether related to the COVID-19 pandemic or other health needs of the population, and it can be a viable strategy for the provision of care to vulnerable populations and those living in remote areas.
