Our findings suggest that residual SARS-CoV-2 can persist in patients who have recovered from mild COVID-19 and that there is a significant association between viral persistence and long COVID symptoms. Further research is needed to verify a mechanistic link and identify potential targets to improve long COVID symptoms.

The precise mechanisms underlying transmission of functions of these associations are often difficult to describe, due to the difficulty in separating the symbiotic partners. This is especially the case for plant-bacteria hereditary symbioses, which lack experimentally tractable model systems. Here, we demonstrate the potential of the leaf symbiosis between the wild yam Dioscorea sansibarensis and the bacterium Orrella dioscoreae (O. dioscoreae) as a model system for hereditary symbiosis. O. dioscoreae is easy to grow and genetically manipulate, which is unusual for hereditary symbionts. These properties allowed us to design an effective antimicrobial treatment to rid plants of bacteria and generate whole aposymbiotic plants, which can later be re-inoculated with bacterial cultures. Aposymbiotic plants did not differ morphologically from symbiotic plants and the leaf forerunner tip containing the symbiotic glands formed normally even in the absence of bacteria, but microscopic differences between symbiotic and aposymbiotic glands highlight the influence of bacteria on the development of trichomes and secretion of mucilage. This is to our knowledge the first leaf symbiosis where both host and symbiont can be grown separately and where the symbiont can be genetically altered and reintroduced to the host.

by Xinyi Zhou, Tengda Huang, Hongyuan Pan, Ao Du, Tian Wu, Jiang Lan, Yujia Song, Yue Lv, Fang He, Kefei Yuan Introduction Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of coronavirus disease 2019 (COVID-19), has infected millions of individuals worldwide, which poses a severe threat to human health. COVID-19 is a systemic ailment affecting various tissues and organs, including the lungs and liver. Intrahepatic cholangiocarcinoma (ICC) is one of the most common liver cancer, and cancer patients are particularly at high risk of SARS-CoV-2 infection. Nonetheless, few studies have investigated the impact of COVID-19 on ICC patients. Methods With the methods of systems biology and bioinformatics, this study explored the link between COVID-19 and ICC, and searched for potential therapeutic drugs. Results This study identified a total of 70 common differentially expressed genes (DEGs) shared by both diseases, shedding light on their shared functionalities. Enrichment analysis pinpointed metabolism and immunity as the primary areas influenced by these common genes. Subsequently, through protein-protein interaction (PPI) network analysis, we identified SCD, ACSL5, ACAT2, HSD17B4, ALDOA, ACSS1, ACADSB, CYP51A1, PSAT1, and HKDC1 as hub genes. Additionally, 44 transcription factors (TFs) and 112 microRNAs (miRNAs) were forecasted to regulate the hub genes. Most importantly, several drug candidates (Periodate-oxidized adenosine, Desipramine, Quercetin, Perfluoroheptanoic acid, Tetrandrine, Pentadecafluorooctanoic acid, Benzo[a]pyrene, SARIN, Dorzolamide, 8-Bromo-cAMP) may prove effective in treating ICC and COVID-19. Conclusion This study is expected to provide valuable references and potential drugs for future research and treatment of COVID-19 and ICC.

by Pacifique Karekezi, Jean Damascene Nzabakiriraho, Ezra Gayawan In sub-Saharan Africa, malaria and anemia contribute substantially to the high burden of morbidity and mortality among under-five children. In Rwanda, both diseases have remained public health challenge over the years in spite of the numerous intervention programs and policies put in place. This study aimed at understanding the geographical variations between the joint and specific risks of both diseases in the country while quantifying the effects of some socio-demographic and climatic factors. Using data extracted from Rwanda Demographic and Health Survey, a shared component model was conceived and inference was based on integrated nested Laplace approximation. The study findings revealed similar spatial patterns for the risk of malaria and the shared risks of both diseases, thus confirming the strong link between malaria and anaemia. The spatial patterns revealed that the risks for contracting both diseases are higher among children living in the districts of Rutsiro, Nyabihu, Rusizi, Ruhango, and Gisagara. The risks for both diseases are significantly associated with type of place of residence, sex of household head, ownership of bed net, wealth index and mother’s educational attainment. Temperature and precipitation also have substantial association with both diseases. When developing malaria intervention programs and policies, it is important to take into account climatic and environmental variability in Rwanda. Also, potential intervention initiatives focusing on the lowest wealth index, children of uneducated mothers, and high risky regions need to be reinforced.

by Patricia Martins, Richardson Warley Siqueira Luzia, Jair Alves Pereira Filho, Kelly Silva Welsh, Cíntia Fuzikawa, Rodrigo Nicolato, Márcia Mascarenhas Alemão, Márcio Augusto Gonçalves, José Carlos Cavalheiro, Ianny Dumont Ávila, Ricardo Teixeira Veiga Burnout is most commonly defined as a syndrome characterized by emotional exhaustion, cynicism, and ineffectiveness, which occurs in response to chronic stressors at work. It can adversely affect health workers’ physical and mental health, and the quality of care provided. The COVID-19 pandemic increased stressors and could impact burnout prevalence in this group. There is a lack of information regarding the prevalence of burnout among hospital health workers in Brazil. A newer definition of burnout has been proposed that considers three different clinical profiles: the frenetic, underchallenged and worn-out subtypes. This differentiation could lead to interventions tailored for each subtype. The present study aimed to estimate the prevalence of burnout, its subtypes, and associated factors in workers of a public hospital network in Brazil, during the pandemic. A total of 143 randomly selected participants answered an online form that included sociodemographic and occupational items, and the Burnout Clinical Subtypes Questionnaire, a summarized version. This questionnaire evaluates three burnout dimensions (overload, lack of development, neglect) that can be used to discriminate the three burnout subtypes (frenetic, underchallenged, worn-out, respectively); higher scores indicate higher burnout levels. The prevalence of burnout was high (53.85%), similar to other studies during the pandemic. The most common subtypes were ‘frenetic’ (34.97%), characterized by increased efforts to meet work demands, to the point of neglecting personal needs, and ‘lack of development’ (23.78%), characterized by a sense that work is uninteresting and does not contribute to personal development, and a perfunctory behavior towards tasks. Age was associated with burnout: workers with less than 51 years presented higher levels of burnout. These findings indicate the need for effective interventions to prevent and/or treat burnout. The assessment of burnout subtypes can allow managers to better understand the processes affecting employees, and inform actions to improve workforce health.

Abstract Background Sepsis is a recognized global health challenge that places a considerable disease burden on countries. Although there has been some progress in the study of sepsis, the mortality rate of sepsis remains high. The relationship between serum osmolality and the prognosis of patients with sepsis is unclear. Method Patients with sepsis who met the criteria in the Medical Information Mart for Intensive Care IV database were included in the study. Hazard ratios (HRs) and 95% confidence intervals (CIs) were determined using multivariable Cox regression. The relationship between serum osmolality and the 28-day mortality risk in patients with sepsis was investigated using curve fitting, and inflection points were calculated. Results A total of 13,219 patients with sepsis were enrolled in the study; the mean age was 65.1 years, 56.9 % were male, and the 28-day mortality rate was 18.8 %. After adjusting for covariates, the risk of 28-day mortality was elevated by 99% (HR 1.99, 95%CI 1.74-2.28) in the highest quintile of serum osmolality (Q5 >303.21) and by 59% (HR 1.59, 95%CI 1.39-1.83) in the lowest quintile (Q1 ≤285.80), as compared to the reference quintile (Q3 291.38-296.29). The results of the curve fitting showed a U-shaped relationship between serum osmolality and the risk of 28-day mortality, with an inflection point of 286.9 mmol/L. Conclusion There is a U-shaped relationship between serum osmolality and the 28-day mortality risk in patients with sepsis. Higher or lower serum osmolality is associated with an increased risk of mortality in patients with sepsis. Patients with sepsis have a lower risk of mortality when their osmolality is 285.80-296.29 mmol/L.

Abstract Background Mycoplasma genitalium (MG) is an emerging sexually transmitted infection, often harboring resistance-associated mutations to azithromycin (AZM). Global surveillance has been mandated to tackle the burden caused by MG, yet no data are available for Austria. Thus, we aimed to investigate the prevalence of MG, disease characteristics, and treatment outcomes at the largest Austrian HIV—and STI clinic. Methods All MG test results at the Medical University of Vienna from 02/2019 to 03/2022 were evaluated. Azithromycin resistance testing was implemented in 03/2021. Results Among 2671 MG tests, 199 distinct and mostly asymptomatic (68%; 135/199) MG infections were identified, affecting 10% (178/1775) of all individuals. This study included 83% (1479/1775) men, 53% (940/1775) men who have sex with men (MSM), 31% (540/1754) HIV+, and 15% (267/1775) who were using HIV pre-exposure prophylaxis (PrEP). In logistic regression analysis, ‘MSM’ (aOR 2.55 (95% CI 1.65–3.92)), ‘use of PrEP’ (aOR 2.29 (95% CI 1.58–3.32)), and ‘history of syphilis’ (aOR 1.57 (95% CI 1.01–2.24) were independent predictors for MG infections. Eighty-nine percent (178/199) received treatment: 11% (21/178) doxycycline (2 weeks), 52% (92/178) AZM (5 days), and 37% ( 65/178) moxifloxacin (7–10 days) and 60% (106/178) had follow-up data available showing negative tests in 63% (5/8), 76% (44/58) and 85% (34/40), respectively. AZM resistance analysis was available for 57% (114/199)) and detected in 68% (78/114). Resistance-guided therapy achieved a cure in 87% (53/61), yet, empiric AZM-treatment (prior to 03/2021) cleared 68% (26/38). Conclusions Mycoplasma genitalium was readily detected in this Austrian observational study, affected predominantly MSM and often presented as asymptomatic disease. We observed a worryingly high prevalence of AZM resistance mutations; however, empiric AZM treatment cleared twice as many MG infections as expected.

Summary B and T cells collaborate to drive autoimmune disease (AID). Historically, B and T cell (B-T cell) co-interaction was targeted through different pathways such as alemtuzumab, abatacept, and dapirolizumab with variable impact on B cell depletion (BCD), whereas the majority of patients with AID including rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis and organ transplantation benefit from targeted BCD with anti-CD20 monoclonal antibodies such as rituximab, ocrelizumab or ofatumumab. Refractory AID is a significant problem for patients with incomplete BCD with a greater frequency of IgD-CD27+ switched memory B cells, CD19+CD20- B cells and plasma cells that are not directly targeted by anti-CD20 antibodies, whereas most lymphoid tissue plasma cells express CD19. Furthermore, B-T cell collaboration is predominant in lymphoid tissues and at sites of inflammation such as the joint and kidney, where BCD may be inefficient, due to limited access to key effector cells. In the treatment of cancer, chimeric antigen receptor (CAR) T cell therapy and T cell engagers (TCE) that recruit T cells to induce B cell cytotoxicity have delivered promising results for anti-CD19 CAR T cell therapies, the CD19 TCE blinatumomab and CD20 TCE such as mosunetuzumab, glofitamab or epcoritamab. Limited evidence suggests that anti-CD19 CAR T cell therapy may be effective in managing refractory AID whereas we await evaluation of TCE for use in non-oncological indications. Therefore, here, we discuss the potential mechanistic advantages of novel therapies that rely on T cells as effector cells to disrupt B-T cell collaboration toward overcoming rituximab-resistant AID.

Objective: Adolescents with perinatally-acquired HIV (AWH) are at an increased risk of poor cognitive development but the underlying mechanisms remain unclear. Circulating galectin-9 (Gal-9) has been associated with increased inflammation and multi-morbidity in adults with HIV despite anti-retroviral therapy (ART), however, relationship between Gal-9 in AWH and cognition remain unexplored. Design: A cross-sectional study of two independent age-matched cohorts from India [AWH on ART (n = 15), ART-naïve (n = 15), and adolescents without HIV (AWOH; n = 10)] and Myanmar [AWH on ART (n = 54) and AWOH (n = 22)] were studied. Adolescents from Myanmar underwent standardized cognitive tests. Methods: Plasma Gal-9 and soluble mediators were measured by immunoassays and cellular immune markers by flow cytometry. We used Mann-Whitney U tests to determine group-wise differences, Spearman\'s correlation for associations and machine learning (ML) to identify a classifier of cognitive status (impaired vs. unimpaired) built from clinical (age, sex, HIV status) and immunological markers. Results: Gal-9 levels were elevated in ART-treated AWH compared to AWOH in both cohorts (all p

Introduction: This study aimed to investigate the association between obesity and cancer risk as well as site-specific cancer risks in adults with HIV using a nationwide health screening database in Korea. Methods: Of the 16,671 adults with a new diagnosis of HIV from 2004 to 2020, 456 incident cancer cases and 1,814 individually matched controls by sex, year of birth, year of HIV diagnosis, and follow-up duration (1:4 ratio) were included in this nested case-control study. The association between obesity (body mass index ≥25 kg/m2) and cancer risks was estimated and presented as odds ratios (ORs) and 95% confidence intervals (CIs). Results: Of the 456 cancer incident cases, there were 146 AIDS-defining cancer cases and 310 non-AIDS-defining cancer cases. Compared with non-obese adults with HIV, obese adults with HIV were at higher risk of non-AIDS-defining cancer (OR = 1.478, 95% CI = 1.118–1.955). Otherwise, the overall risk of AIDS-defining cancer (OR = 0.816, 95% CI = 0.520–1.279) and each type of AIDS-defining cancer (Kaposi sarcoma and non-Hodgkin\'s lymphoma) were not high in obese adults with HIV. Of the specific types of non-AIDS-defining cancers, obesity was associated with an increased risk of colorectal cancer (OR = 3.090, 95% CI = 1.110–8.604) and liver, bile duct, and pancreatic cancers (OR = 2.532, 95% CI = 1.141–5.617). Conclusions: Obesity, which is one of the important health concerns in HIV management, was associated with an increased risk of non-AIDS-defining cancer but not AIDS-defining cancer.

Objectives: Antiretroviral therapy (ART) accounts for a considerable proportion of HIV care expenses. In June 2021, a Dutch healthcare insurer implemented a mandatory policy to de-simplify branded RPV/TDF/FTC (Eviplera®) into a two-tablet regimen containing rilpivirine (Edurant®) plus generic TDF/FTC as part of cost-saving measures. The objectives of this study were to evaluate (1) the acceptance of this policy, (2) the trends in antiretroviral therapy dispensation, and (3) cost developments. Design: A retrospective database study. Methods: In this study, medication dispensation data were obtained from the Dutch Foundation for Pharmaceutical Statistics (SFK). This database covers 98% of all medication dispensations from Dutch pharmacies including people with HIV who receive ART. We received pseudonymized data exclusively from individuals insured by the insurer for the years 2020–2022. Costs were calculated using Dutch drug prices for each year. Results: In June 2021, 128 people with HIV were on branded RPV/TDF/FTC. Following the policy implementation, 59 (46%) had switched to RPV + generic TDF/FTC, but after 1.5 years, only 17/128 individuals (13%) used the proposed two-tablet regimen. The other 111/128 used RPV/TDF/FTC with prescriptions for ’medical necessity’ (n = 29), switched to RPV/TAF/FTC (n = 51), or other ART (n = 31). Despite expectations of cost-savings, costs increased from €72,988 in May 2021 to €75,649 in May 2022. Conclusions: A mandatory switch from an STR to a TTR in people with HIV proved unsuccessful, marked by low acceptance, and increased costs after one year. This underscores the necessity of incorporating patient and prescriber involvement in changing medication policies. Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.

Objective: The objective of this study is to use GPS technology to determine if violent and property crime exposure to participants activity spaces affect outcomes of the HIV prevention and care continuum (PCC) among Young Black sexually minoritized men (YBSMM) and Transgender women (TW), a subgroup at high vulnerability for new HIV diagnoses. Exposure to violent and property crime adversely affects a variety of acute and chronic medical conditions; however the relationship between exposure to violent and property crime and HIV risk (e.g., PrEP non use) is unknown. Spatial analytic analysis using dynamic Global Position Systems (GPS) technology can accurately detect geospatial associations between the crime exposure and objective HIV related outcomes. Methods: With the Neighborhoods and Networks (N2) Cohort Study, GPS technology to identify the activity space of 286 (123 PLWH and 163 PWoH) YBSMM & TW living in Chicago, IL, to identified spatial associations between violent and property crime exposures with HIV PCC outcomes. Results: We found that YBSMM & TGW with higher exposure areas with higher levels of violent crime were less likely to use HIV preexposure prophylaxis (PrEP) therapy (aOR 0.76, 95% CI 0.63-0.91, p = 0.03). Conclusion: This study demonstrates the importance of clinical providers to consider violent crime as a potential sociostructural barrier that may impact medication adherence and health care outcomes among vulnerable populations. Additionally, GPS technology offers an alternative data analytic process that may be used to future studies to assist in identifying barriers to ending the HIV epidemic.

Background: People living with HIV require reliable access to and adequate supply of antiretroviral therapy (ART) for viral suppression. The Deliver Health Study, a randomized trial conducted during the COVID-19 pandemic, found that home-delivered ART significantly increased viral suppression compared to clinic-based care. The effect of changing COVID-19 alert levels on self-reported ART use has not been quantified. Setting: KwaZulu-Natal, South Africa. Methods: Adults living with HIV were followed in the Deliver Health Study during October 2019-December 2020. We used difference-in-differences (DiD) to estimate the effect of changing COVID-19 alert levels during three distinct periods on self-reported missed ART doses (missed 0 vs. 1 doses in past week) for participants receiving home-delivered vs. clinic-based refills. We additionally estimated the effect of changing COVID-19 alert levels on late clinic ART refill visits (late vs. on-time). We used relative risk regression for both binary outcomes. Results: Of 155 participants, 46% were women and median age was 36 years. The mean number of missed weekly doses was 0.11, 0, and 0.12 in the home-delivery group and 0.09, 0.08, and 0.18 in the clinic group during periods 1, 2, and 3, respectively. There were no differences in relative risk (RR) of self-reported daily ART use between refill groups when comparing across periods (DiDperiod 2 vs. 1=1.05; 95% confidence interval [CI]: 0.97, 1.13 and DiDperiod 3 vs. 2=0.99; 95% CI: 0.91, 1.08). In the clinic group, the risk of late refill visits was significantly higher during COVID-19 restrictions (vs. before alert level 5 implementation) and even after the COVID-19 alert level was downgraded to level 1 (RRperiod 2 vs. 1=1.83, 95% CI: 1.34, 2.51 and RRperiod 3 vs. 2=1.71; 95% CI: 1.43, 2.04). Conclusion: The COVID-19 pandemic did not differentially impact self-reported ART adherence by method of ART refills, but the risk of late clinic refill visits was significantly higher during COVID-19 restrictions and sustained after restrictions were loosened.

Background: In Kenya, of the 82,000 children living with HIV; only 59% of these children are receiving ART, and 67% of these are virally suppressed. Early in the COVID-19 pandemic, the Ministry of Health recommended three multi-month dispensing (3MMD) of ART to all people living with HIV, including children. This study assess the association between 3MMD and clinical outcomes among children in Western Kenya. Settings and Methods: We conducted a retrospective cohort study using routinely collected de-identified patient-level data from 43 facilities in Kisii and Migori counties. The study included children 2-9 years old who had been previously initiated on ART and sought HIV services between March 01, 2020, and March 30, 2021. We used generalized linear models with Poisson regression models to assess the association of MMD on retention at 6 months and viral suppression (

Background: Ukraine has implemented ambitious HIV-prevention programs since 1999 and began offering pre-exposure prophylaxis (PrEP) in 2017. Little is known about PrEP uptake and persistence in this setting. Setting: We analyzed data from 40 facilities providing PrEP in 11 oblasts (regions) of Ukraine between October 2020-February 2022. Methods: We estimated the time between PrEP visits and conducted Kaplan-Meier analyses to estimate retention on PrEP stratified by sex, age, and key populations (KPs): men who have sex with men (MSM), people who inject drugs (PWID), sex workers (SW), discordant couples and others vulnerable to HIV acquisition (DC/Other). We used Cox regression to estimate risk of PrEP discontinuation by KP group and sex, adjusting for age. Results: Overall, 2,033 clients initiated PrEP across regions; the majority (51%) were DC/Other, 22% were MSM, 22% were PWID, and 5% were SW. The overall three-month persistence was 52.3% (95% confidence interval [CI]: 49.9-54.8%) and was lowest among MSM (46.7%; 95% CI: 41.9-52.2%) and SW (25.9%; 95% CI: 18.2-36.9%) (p

People who were infected with SARS-CoV-2 tended to score slightly worse on cognitive assessments—particularly in memory, reasoning, and tasks that require executive function—than those who were not infected, according to data from about 113 000 participants in England. The score was the equivalent of a 3-point loss on an IQ scale, the researchers reported in the New England Journal of Medicine.

To the Editor A recent Viewpoint elucidated the potential of IHL in protecting the sacredness of health care. But, they also highlighted the difficulties in implementing its lofty principles. Throughout most modern wars, protection of the right to health embodied in these humanitarian principles has been violated, by targeting civilians and their living spaces. The brutal October 7 Hamas attack that included rapes, burning of infants, torching individuals while still alive, and killing of parents in front of their children, as well as hostage-taking, unfortunately continues this horrific pattern of modern terrorist warfare. Given the importance of health, even in war, Israel has struggled—putting its own soldiers at risk—to protect civilians within Gazan hospitals that are used as command and control centers and weapons depots and to provide humanitarian aid corridors when few, if any, of its neighbors will aid (or resettle) fleeing Gazans. Yet, beyond the current conflict, how could a right to health contribute to a peaceful Gaza? Under international human rights law, states are required to maintain a functioning health care system as part of their obligation to fulfill the right to health. Within existing international law and a stable Gaza, Israel could work collaboratively with multiple sectors across Gazan communities, and a revised Ministry of Health, to coordinate tailored community-based health care resources. As during the height of the COVID-19 pandemic, Coordination of Government Activities in the Territories trained Gazan nurses, Israel provided aid to Gaza, and Hebrew University of Jerusalem has continued to train Gazan and other Arab medical residents. These efforts could be reestablished with international cooperation. And, with a focus on the right to health, perhaps enduring peace would be a secondary outcome.

To the Editor As a physician with a disability, I read with interest the Viewpoint “Revising NIH’s Mission Statement to Remove Ableist Language.” I always wanted to be a physician, but had a spinal cord stroke in 1972 at age 17. Initially, I was unable to walk or stand. I learned to walk again, although always with some difficulty. Despite that difficulty, I stuck with my goal, finished high school, graduated from college and medical school, completed an internal medicine residency, and practiced for 6 years as an internist. I then completed an infectious diseases fellowship and went into practice as an infectious diseases physician. Fifteen years ago, my legs started to deteriorate further, and eventually I started using a power chair to get around at work.

OBJECTIVES: Occurrence of post-intubation laryngotracheal stenosis (LTS) with respect to COVID-19 status. DESIGN: Retrospective cross-sectional inpatient database. SETTING: Eleven Midwest academic and community hospitals, United States. PATIENTS: Adults, mechanically ventilated, from January 2020 to August 2022, who were subsequently readmitted within 6 months with a new diagnosis of LTS. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Six thousand eight hundred fifty-one COVID-19 negative and 1316 COVID-19 positive patients were intubated and had similar distribution by age (median 63.77 vs. 63.16 yr old), sex (male, 60.8%; n = 4173 vs. 60%; n = 789), endotracheal tube size (≥ 7.5, 75.8%; n = 5192 vs. 75.5%; n = 994), and comorbidities. The ICU length of stay (median [interquartile range (IQR)], 7.23 d [2.13–16.67 d] vs. 3.95 d [1.91–8.88 d]) and mechanical ventilation days (median [IQR], 5.57 d [1.01–14.18 d] vs. 1.37 d [0.35–4.72 d]) were longer in the COVID-19 positive group. The occurrence of LTS was double in the COVID-19 positive group (12.7%, n = 168 vs. 6.4%, n = 440; p < 0.001) and was most commonly diagnosed within 60 days of intubation. In multivariate analysis, the risk of LTS increased by 2% with each additional ICU day (hazard ratio [HR], 1.02; 95% CI, 1.02–1.03; p < 0.001), by 3% with each additional day of ventilation (HR, 1.03; 95% CI, 1.02–1.04; p < 0.001), and by 52% for each additional reintubation (HR, 1.52; 95% CI, 1.36–1.71; p < 0.001). We observed no significant association COVID-19 status and risk of LTS. CONCLUSIONS: The occurrence of post-intubation LTS was double in a COVID-19 positive cohort, with higher risk with increasing number of days intubated, days in the ICU and especially with the number of reintubations. COVID-19 status was not an independent risk factor for LTS.

Abstract The use of fluorescent proteins (FPs) in Plasmodium parasites has been key to understand the biology of this obligate intracellular protozoon. FPs like the green fluorescent protein (GFP) enabled to explore protein localization, promoter activity as well as dynamic processes like protein export and endocytosis. Furthermore, FP biosensors have provided detailed information on physiological parameters at the subcellular level, and fluorescent reporter lines greatly extended the malariology toolbox. Still, in order to achieve optimal results, it is crucial to know exactly the properties of the FP of choice and the genetic scenario in which it will be used. This review highlights advantages and disadvantages of available landing sites and promoters that have been successfully applied for the ectopic expression of FPs in Plasmodium berghei and Plasmodium falciparum. Furthermore, the properties of newly developed FPs beyond DsRed and EGFP, in the visualization of cells and cellular structures as well as in the sensing of small molecules are discussed.

Abstract Background Microsporidia MB, an endosymbiont naturally found in Anopheles mosquitoes inhibits transmission of Plasmodium and is a promising candidate for a transmission-blocking strategy that may involve mosquito release. A rapid assessment was carried out to develop insight into sociodemographic factors, public health concerns, and malaria awareness, management, and prevention practices with the willingness to accept and participate in Microsporidia MB-based transmission-blocking strategy to develop an informed stakeholder engagement process. Methods The assessment consisted of a survey conducted in two communities in western Kenya that involved administering a questionnaire consisting of structured, semi-structured, and open questions to 8108 household heads. Results There was an overall high level of willingness to accept (81%) and participate in the implementation of the strategy (96%). Although the willingness to accept was similar in both communities, Ombeyi community was more willing to participate (OR 22, 95% CI 13–36). Women were less willing to accept (OR 0.8, 95% CI 0.7–0.9) compared to men due to fear of increased mosquito bites near homes. Household heads with incomplete primary education were more willing to accept (OR 1.6, 95% CI 01.2–2.2) compared to those educated to primary level or higher. Perceiving malaria as a moderate or low public health issue was also associated with a lower willingness to accept and participate. Experience of > 3 malaria cases in the family over the last six months and knowledge that malaria is transmitted by only mosquito bites, increased the willingness to accept but reduced the willingness to participate. Awareness of malaria control methods based on mosquitoes that cannot transmit malaria increases the willingness to participate. Conclusion The study showed a high level of willingness to accept and participate in a Microsporidia MB-based strategy in the community, which is influenced by several factors such as community, disease risk perception, gender, education level, knowledge, and experience of malaria. Further research will need to focus on understanding the concerns of women, educated, and employed community members, and factors that contribute to the lower disease risk perception. This improved understanding will lead to the development of an effective communication strategy.

Abstract Purpose Children with congenital heart disease (CHD) from low- to middle-income countries (LMIC) are suspected to have a high prevalence of antibiotic-resistant microorganisms (ARMOs) carriage, but data are currently lacking. Carriage of ARMOs could impact the post-operative course in pediatric intensive care unit (PICU). The aim of the study was to assess the prevalence of ARMOs carriage in children with CHD from LMIC and its impact on post-operative outcomes. Methods This was a retrospective monocentric study from 01/2019 to 12/2022. Included patients were children (0–18 years) from a LMIC admitted after CHD surgery and with AMRO screening performed the week before. Infections and post-operative evolution were compared based on ARMOs carriage status. Findings Among 224 surgeries (median age 38.5 months (IQR 22–85.5)), ARMOs carriage was evidenced in 95 cases (42.4%). Main organisms isolated were Extended Spectrum Beta-Lactamase (ESBL) producing E. coli (75/224) 33.5%)) and ESBL-K. pneumoniae (30/224) 13.4%)). Median mechanical ventilation duration was 1 day (IQR 0–1), PICU stay 3 days (IQR 2–4) and hospital stay 6.5 days (IQR 5–10). A total of 17 infectious episodes occurred in 15 patients, mostly consisting in hospital-acquired pneumonia (HAP) (12/17). Only two infections were caused by a colonizing ARMO. Occurrence of infections and patients’ outcome were similar between ARMO carriers and non-carriers. Higher use of carbapenems (6 (6.3%) vs 1 (0.8%), p = 0.04) and a trend to a higher use of vancomycin (14 (13.7%) vs 9 (6.9%), p = 0.04) in case of ARMOs carriage. Applying current guidelines, negative swab screening could have led to sparing most of empirical vancomycin therapy (11/12) for HAP based on current guidelines. Conclusion Prevalence of AMROs carriage is high in children from LMIC and has a limited impact on patients’ outcome. However, ARMOs carriage leads to higher consumption of antibiotics. Screening may help saving use of broad-spectrum antibiotic in non-carrier patients.

Abstract Purpose Patients with non-beta-hemolytic streptococcal bacteremia (NBHSB) are at risk of infective endocarditis (IE). Patients with cardiac implantable electronic device (CIED) have been described to have an increased risk of IE. The aim of the study was to describe a population-based cohort of patients with NBHSB and CIED and variables associated with IE and recurrent NBHSB. Methods All episodes with NBHSB in blood culture from 2015 to 2018 in a population of 1.3 million inhabitants were collected from the Clinical Microbiology Laboratory, Lund, Sweden. Through medical records, patients with CIED during NBHSB were identified and clinical data were collected. Patients were followed 365 days after NBHSB. Results Eighty-five episodes in 79 patients with CIED and NBHSB constituted the cohort. Eight patients (10%) were diagnosed with definite IE during the first episode, five of whom also had heart valve prosthesis (HVP). In 39 patients (49%) transesophageal echocardiography (TEE) was performed of which six indicated IE. Four patients had the CIED extracted. Twenty-four patients did not survive (30%) the study period. Four patients had a recurrent infection with NBHSB with the same species, three of whom had HVP and had been evaluated with TEE with a negative result during the first episode and diagnosed with IE during the recurrency. Conclusion The study did not find a high risk of IE in patients with NBHSB and CIED. Most cases of IE were in conjunction with a simultaneous HVP. A management algorithm is suggested.

Abstract Purpose Very low birth weight (VLBW) infants are at a risk of spontaneous focal intestinal perforation (FIP). Treatment includes supportive care, antibiotics, and drainage with/without surgery. Broad-spectrum antibiotic agents like carbapenems are applied frequently, although their use is not well-supported by the limited evidence of causal pathogens. We hypothesize that the use of carbapenems may not be necessary in VLBW infants with FIP. Our primary objective was to evaluate the antimicrobial use in VLBW infants with FIP in a cohort of the German Neonatal Network (GNN). The secondary objective was to characterize a subset in detail as a benchmark for future targets of stewardship. Methods Data on VLBW infants with FIP was collected prospectively within the GNN, a collaboration of 68 neonatal intensive care units (NICU). With regards to the primary objective, patient characteristics and antimicrobial treatment were extracted from the predefined GNN database. To address our secondary objective, an additional on-site assessment of laboratory and microbiological culture results were performed. Results In the GNN cohort, 613/21,646 enrolled infants (2.8%) developed FIP requiring surgery. They were frequently treated with carbapenems (500/613 (81.6%)) and vancomycin (497/613 (81.1%)). In a subset of 124 VLBW infants, 77 (72.6%) had proof of gram-positive bacteria in the abdominal cavity, coagulase-negative staphylococci (CoNS) predominantly. Despite the low prevalence of gram-negative bacteria (n = 6 (4.8%)), the combination of meropenem and vancomycin was prescribed most frequently (n = 96 (78.0%)). Conclusion The use of carbapenems as broad-spectrum antimicrobials agents might not be justified in most VLBW infants with FIP. Knowledge on the development of the neonatal gut microbiota, local resistance patterns and individual microbiological findings should be taken into consideration when implementing antimicrobial stewardship programs (ASPs).

Despite the low prevalence of gram-negative bacteria (n = 6 (4.8%)), the combination of meropenem and vancomycin was prescribed most frequently (n = 96 (78.0%)). Conclusion The use of carbapenems as broad-spectrum antimicrobials agents might not be justified in most VLBW infants with FIP. Knowledge on the development of the neonatal gut microbiota, local resistance patterns and individual microbiological findings should be taken into consideration when implementing antimicrobial stewardship programs (ASPs).

Abstract Purpose Sepsis is a life-threatening organ dysfunction caused by dysregulated host response to infection. The purpose of the study was to measure the associations of specific exposures (deprivation, ethnicity, and clinical characteristics) with incident sepsis and case fatality. Methods Two research databases in England were used including anonymized patient-level records from primary care linked to hospital admission, death certificate, and small-area deprivation. Sepsis cases aged 65–100 years were matched to up to six controls. Predictors for sepsis (including 60 clinical conditions) were evaluated using logistic and random forest models; case fatality rates were analyzed using logistic models. Results 108,317 community-acquired sepsis cases were analyzed. Severe frailty was strongly associated with the risk of developing sepsis (crude odds ratio [OR] 14.93; 95% confidence interval [CI] 14.37–15.52). The quintile with most deprived patients showed an increased sepsis risk (crude OR 1.48; 95% CI 1.45–1.51) compared to least deprived quintile. Strong predictors for sepsis included antibiotic exposure in prior 2 months, being house bound, having cancer, learning disability, and diabetes mellitus. Severely frail patients had a case fatality rate of 42.0% compared to 24.0% in non-frail patients (adjusted OR 1.53; 95% CI 1.41–1.65). Sepsis cases with recent prior antibiotic exposure died less frequently compared to non-users (adjusted OR 0.7; 95% CI 0.72–0.76). Case fatality strongly decreased over calendar time. Conclusion Given the variety of predictors and their level of associations for developing sepsis, there is a need for prediction models for risk of developing sepsis that can help to target preventative antibiotic therapy.

There were an estimated 155 million tuberculosis (TB) survivors globally as of 2020 [1]. However, the risk of mortality among TB survivors is thrice that of people who have never suffered TB [2]. Early identification of risk factors for long-term mortality in people with TB, especially in rural areas where studies have found a four-fold increase in mortality, could significantly improve their long-term survival [3]. This study aimed to determine the incidence and predictors of mortality among TB survivors at a rural tertiary hospital in Uganda.

Abstract Obesity and type 2 diabetes (DM) are risk factors for severe COVID-19 outcomes, which disproportionately affect South Asian populations. This study aims to investigate the humoral and cellular immune responses to SARS-CoV-2 in adult COVID-19 survivors with obesity and DM in Bangladesh. In this cross-sectional study, SARS-CoV-2-specific antibody and T cell responses were investigated in 63 healthy and 75 PCR-confirmed COVID-19 recovered individuals in Bangladesh, during the pre-vaccination first wave of the COVID-19 pandemic in 2020. In COVID-19 survivors, SARS-CoV-2 infection induced robust antibody and T cell responses, which correlated with disease severity. After adjusting for age, sex, DM status, disease severity, and time since onset of symptoms, obesity was associated with decreased neutralising antibody titers, and increased SARS-CoV-2 spike-specific IFN-γ response along with increased proliferation and IL-2 production by CD8+ T cells. In contrast, DM was not associated with SARS-CoV-2-specific antibody and T cell responses after adjustment for obesity and other confounders. Obesity is associated with lower neutralising antibody levels and higher T cell responses to SARS-CoV-2 post COVID-19 recovery, while antibody or T cell responses remain unaltered in DM.

Abstract Background QUANTI-TAF aimed to establish tenofovir-diphosphate/emtricitabine-triphosphate (TFV-DP/FTC-TP) adherence benchmarks in dried blood spots (DBS) for persons with HIV (PWH) receiving tenofovir alafenamide/emtricitabine (TAF/FTC)-based antiretroviral therapy (ART).Methods During a 16-week pharmacokinetic study, PWH received TAF/FTC-based ART co-encapsulated with an ingestible sensor to directly measure cumulative (enrollment to final visit) and 10-day adherence. At monthly visits, intraerythrocytic concentrations of TAF/FTC anabolites (TFV-DP/FTC-TP) in DBS were quantified by LC-MS/MS and summarized at steady-state (week 12 or 16) as median (IQR). Linear mixed-effects models evaluated factors associated with TFV-DP/FTC-TP.Results 84 participants (86% male, 11% female, and 4% transgender), predominantly receiving bictegravir/TAF/FTC (73%) enrolled. 92% completed week 12 or 16 (94% receiving unboosted ART).
