    Abstract Objective: We aimed to evaluate the efficacy of PrEP (pre-exposure prophylaxis) training sessions for OBGYN (obstetrician gynaecologist) providers given underutilisation of PrEP among women despite a high HIV burden.
    Methods: Three separate training sessions were held for providers in the OBGYN department at an academic medical centre in New York City from 2019 to 2021. The 1-hour training sessions were conducted by HIV specialists as in-person lectures or online live lectures. Participants were surveyed after the training on metrics of PrEP awareness, knowledge and comfort with management. Two-sample t-tests were used to compare difference in proportions of binomial variables and difference in means of Likert-scored answers pretraining and post-training events.
    Results: 63 respondents completed the surveys. There were low rates (13%) of past PrEP prescription among the respondents, while awareness of PrEP as an HIV prevention strategy was high before (95%) and after (98%) the training. After the training, there was an increase in understanding the epidemiology of HIV transmission (40% to 97%, p<0.00), familiarity with the PrEP clinical trials (18% to 97%, p<0.00), comfort in determining PrEP candidacy (mean score 2.3 to 4.1, p<0.00) and comfort prescribing PrEP (mean score 2.0 to 3.6, p<0.00). After the trainings, the majority of participants reported feeling 'comfortable' or 'very comfortable' in determining candidacy for PrEP and prescribing PrEP with follow-up.
    Conclusion: Implementation of PrEP training courses for OBGYN providers increased knowledge and comfort in identifying and managing patients who may benefit from PrEP services. Increasing training among OBGYN providers serving women at risk for HIV infection is an effective tool to narrow gaps in PrEP access.

    Abstract Since 2015, Mount Sinai HIV/HCV Center of Excellence has implemented two-day HIV and HCV preceptorships for New York State health care. Participants assessed their knowledge of and confidence to perform 13 HIV or 10 HCV prevention- and treatment-related skills, measured on a 4-point Likert scale from "not at all" to "very" knowledgeable/confident at baseline, exit survey, and a recent evaluation. Wilcoxon signed rank sum tests determined mean differences at all three time points. Between baseline to exit assessment and baseline to evaluation assessment, HIV and HCV preceptorship attendees reported significant increases in knowledge for five HIV and three HCV components and confidence for two HIV and three HCV tasks (

    Abstract The production of vaccines of biological origin presents a tremendous challenge for researchers. In this context, animal cell cultures are an excellent alternative for the isolation and production of biologicals against several viruses, since they have an affinity with viruses and a great capacity for their replicability. Different variables have been studied to know the system’s ideal parameters, allowing it to obtain profitable and competitive products. Consequently, this work focuses its efforts on evaluating an alternative for producing an anti-influenza biological from MDCK cells using SuperPro Designer v8.0 software. The process uses the DMEN culture medium supplemented with nutrients as raw material for cell development; the MDCK cells were obtained from a potential scale-up with a final working volume of 500 L, four days of residence time, inoculum volume of 10%, and continuous working mode with up to a total of 7400 h/Yr of work. The scheme has the necessary equipment for the vaccine’s production, infection, and manufacture with yields of up to 416,698 units/h. In addition, it was estimated to be economically viable to produce recombinant vaccines with competitive prices of up to 0.31 USD/unit.

    Abstract Background: The 2022 global mpox outbreak was notable for transmission between persons outside of travel and zoonotic exposures and primarily through intimate contact. An understanding of the presentation of mpox in people with human immunodeficiency virus (HIV) and other immunocompromising conditions and knowledge of the efficacy of tecovirimat continue to evolve.
    Methods: This retrospective study describes clinical features and outcomes of persons with mpox who received tecovirimat. Data were obtained via medical record review of patients prescribed tecovirimat in a health system in New York City during the height of the outbreak in 2022.
    Results: One hundred thirty people received tecovirimat between 1 July and 1 October 2022. People with HIV (n = 80) experienced similar rates of recovery, bacterial superinfections, and hospitalization compared to patients without immunocompromising conditions. Individuals determined to be severely immunocompromised (n = 14) had a higher risk of hospitalization than those without severe immunocompromise (cohort inclusive of those with well-controlled HIV, excluding those without virologic suppression, n = 101): 50% versus 9% (
    Conclusions: There were no significant differences in outcomes between people with HIV when evaluated as a whole and patients without immunocompromising conditions. However, mpox infection was associated with higher rates of hospitalization in those with severe immunocompromise, including patients with HIV/AIDS. Treatment with tecovirimat was well tolerated.Key Points: In our mpox cohort, people with HIV had similar rates of recovery and complications as those without HIV or other immunocompromising conditions. Severe immunocompromise was associated with a higher hospitalization rate. Tecovirimat was well tolerated, with minimal side effects.

    Abstract The present research evaluates the simulation of a system for transforming inland-fisheries wastewater into sustainable fish feed using Designer® software. The data required were obtained from the experimental cultivation of Chlorella sp. in wastewater supplemented with N and P. According to the results, it is possible to produce up to 11,875 kg/year (31.3 kg/d) with a production cost of up to 18 (USD/kg) for dry biomass and 0.19 (USD/bottle) for concentrated biomass. Similarly, it was possible to establish the kinetics of growth of substrate-dependent biomass with a maximum production of 1.25 g/L after 15 days and 98% removal of available N coupled with 20% of P. It is essential to note the final production efficiency may vary depending on uncontrollable variables such as climate and quality of wastewater, among others.

    Abstract Avocado consumption and trade are increasing worldwide, with North America and Europe being the main importing regions. Spain is the major European avocado producer (90% of the production), yet it only supplies 10% of the market. Consequently, more than 90% of the avocados consumed in Europe are imported from overseas, mainly from Chile and Peru. In this work, the Life Cycle Assessment (LCA) impact associated with the transport of two avocado supply chains (short (Spanish) and long (Chilean)) and the effect of the fruit origin and distance of both chains on primary and secondary metabolites from harvest to edible ripeness were evaluated using a gas chromatography-mass spectrometry (GC-MS) and liquid chromatography coupled to diode array detection (LC-DAD) based metabolite analysis. The LCA transport impact of the fresh supply chain from production centers in Chile (Quillota) and Spain (Malaga), and then the distribution to several cities in Europe, suggested road export from Spain to European capitals to have the lowest impact (0.14 to 0.22 kg CO

    Abstract Background: Graft-vs-host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplant. Myopathy is a rare neuromuscular sign of chronic GVHD, with an incidence of less than 4% in all patients. The data are heterogeneous, and no standard criteria exists for diagnosis or treatment.
    Case report: We present the case of an 18-year-old man with acute lymphoblastic leukemia, who developed myopathy associated with GVHD 19 months after allogeneic hematopoietic stem cell transplant from an unrelated donor. The patient had a previous history of acute cutaneous and chronic hepatic GVHD. At the time of symptom onset, the immunosuppressive drugs were tapered. He developed with sudden symmetrical proximal muscle weakness that prevented him from walking. Diagnosis was confirmed using magnetic resonance imaging, electromyography, muscle enzymes, and muscle biopsy results. He initially responded to immunosuppressive therapy but relapsed after quick tapering of prednisone, requiring a prolonged course of steroids and an additional dose of immune globulin intravenous. At the moment of the publication, the patient has 9 months free from GVHD relapse.
    Conclusions: GVHD-associated myopathy is a rare complication of hematopoietic stem cell transplant and must be suspected in patients with sudden proximal muscle weakness and moderate pain. Diagnosis is challenging and must include magnetic resonance imaging, electromyography, muscle enzymes, and muscle biopsy results. Usually, all patients respond adequately to immunosuppression.

    Abstract Objective To study the relationship between county-level COVID-19 outcomes (incidence and mortality) and county-level median household income and status of Medicaid expansion of US counties. Methods Retrospective analysis of 3142 US counties was conducted to study the relationship between County-level median-household-income and COVID-19 incidence and mortality per 100,000 people in US counties, January-20th-2021 through December-6th-2021. County median-household-income was log-transformed and stratified by quartiles. Multilevel-mixed-effects-generalized-linear-modeling adjusted for county socio-demographic and comorbidities and tested for Medicaid-expansion-times-income-quartile interaction on COVID-19 outcomes. Results There was no significant difference in COVID-19 incidence-rate across counties by income quartiles or by Medicaid expansion status. Conversely, for non-Medicaid-expansion states, counties in the lowest income quartile had a 41% increase in COVID-19 mortality-rate compared to counties in the highest income quartile. Mortality-rate was not related to income in counties from Medicaid-expansion states. Conclusions Median-household-income was not related to COVID-19 incidence-rate but negatively related to COVID-19 mortality-rate in US counties of states without Medicaid-expansion.
