AbstractBackgroundCurrent understanding of severe RSV infections in adults is limited by clinical under-recognition. We compared the prevalence, clinical characteristics, and outcomes of RSV infections vs influenza in adults hospitalized with acute respiratory illnesses in a prospective national surveillance network.MethodsHospitalized adults who met a standardized ARI case definition were prospectively enrolled across three respiratory seasons from hospitals participating across all sites of the U.S. Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN, 2016-2019). All participants were tested for RSV and influenza by RT-PCR. Multivariable logistic regression was used to test associations between laboratory-confirmed infection and characteristics and clinical outcomes.ResultsAmong 10,311 hospitalized adults, 6% tested positive for RSV (n=622), 18.8% positive for influenza (n=1,940), and 75.1% negative for RSV and influenza (n=7,749). Congestive Heart Failure (CHF) or Chronic Obstructive Pulmonary Disease (COPD) was more frequent among adults with RSV than influenza (CHF: 37.3% vs. 28.8%, p<0.0001; COPD: 47.6% vs. 35.8%, p<0.0001). Patients with RSV more frequently had longer admissions [OR=1.38 (95% CI: 1.06-1.80) for stays >one week] and mechanical ventilation [OR=1.45 (95% CI: 1.09-1.93)] compared with influenza, but not compared to the influenza negative group [OR=1.03 (95% CI: 0.82-1.28); OR=1.17 (0.91-1.49), respectively.]ConclusionsThe prevalence of RSV across three recent respiratory illness seasons was considerable. Our findings suggest those with RSV might incur worse outcomes than influenza in hospitalized adults and frequently have pre-existing cardiopulmonary conditions. This study informs future vaccination strategies and underscores a need for RSV surveillance among adults experiencing severe ARI.

AbstractBackgroundWith the advent of efficacious oral Direct-acting antivirals (DAAs) for hepatitis C virus(HCV), identification of characteristics associated with adherence is critical to treatment success. We examined correlates of sub-optimal adherence to HCV therapy in a single-arm, multinational, clinical trial.MethodsACTG A5360 enrolled HCV treatment-naïve persons without decompensated cirrhosis from 5 countries. All participants received a 12-weeks course of sofosbuvir/velpatasvir at entry. In-person visits occurred at initiation and week 24, sustained virologic response (SVR) assessment. Adherence at week 4 was collected remotely and was dichotomized optimal (100%, no missed doses) versus sub-optimal (<100%). Correlates of sub-optimal adherence were explored using logistic regression.Results400 participants enrolled; 399 initiated treatment; 395/397 (99%) reported completing at week 24.. Median age was 47 years with 35% female. Among the 368 reporting optimal adherence at week 4 SVR was 96.5% (95% CI [94.1%, 97.9%]) vs. 77.8% (95% CI [59.2%, 89.4%]) p-value < 0.001. In the multivariate model age < 30 years and being a US participant were independently associated with early sub-optimal adherence. Participants < 30 years were 7.1 times more likely to have early sub-optimal adherence compared to their older counterparts.ConclusionSelf-reported optimal adherence at week 4 was associated with SVR. Early self-reported adherence could be used to identify those at higher risk of treatment failure and may benefit from additional support. Younger individuals < 30 years may also be prioritized for additional adherence support.

Sexual differentiation of malaria parasites is essential for transmission, yet the underlying mechanisms are poorly understood. Russell et al. elegantly combined a loss-of-function screen with single-cell RNA-sequencing to identify key factors in this process. Gomes et al. further characterized one of them, MD1, as a regulator contributing to male fate determination.

Wyper, Sara Monteiro Pires, Brecht Devleesschauwer, Antoine Rachas, Panayotis Constantinou, Daniel Levy-Bruhl, Nathalie Beltzer, Anne GallayBackground The World Health Organization declared a pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), on March 11, 2020. The standardized approach of disability-adjusted life years (DALYs) allows for quantifying the combined impact of morbidity and mortality of diseases and injuries. The main objective of this study was to estimate the direct impact of COVID-19 in France in 2020, using DALYs to combine the population health impact of infection fatalities, acute symptomatic infections and their post-acute consequences, in 28 days (baseline) up to 140 days, following the initial infection. Methods National mortality, COVID-19 screening, and hospital admission data were used to calculate DALYs based on the European Burden of Disease Network consensus disease model. Scenario analyses were performed by varying the number of symptomatic cases and duration of symptoms up to a maximum of 140 days, defining COVID-19 deaths using the underlying, and associated, cause of death. Results In 2020, the estimated DALYs due to COVID-19 in France were 990 710 (1472 per 100 000), with 99% of burden due to mortality (982 531 years of life lost, YLL) and 1% due to morbidity (8179 years lived with disability, YLD), following the initial infection. The contribution of YLD reached 375%, assuming the duration of 140 days of post-acute consequences of COVID-19. Post-acute consequences contributed to 49% of the total morbidity burden. The contribution of YLD due to acute symptomatic infections among people younger than 70 years was higher (67%) than among people aged 70 years and above (33%). YLL among people aged 70 years and above, contributed to 74% of the total YLL. Conclusions COVID-19 had a substantial impact on population health in France in 2020. The majority of population health loss was due to mortality. Men had higher population health loss due to COVID-19 than women. Post-acute consequences of COVID-19 had a large contribution to the YLD component of the disease burden, even when we assume the shortest duration of 28 days, long COVID burden is large. Further research is recommended to assess the impact of health inequalities associated with these estimates.…

by Meng Hua, Lin WangThe effectiveness of the blended teaching model in improving university students’ English learning achievement has been frequently reported in China in the post-pandemic era. However, such research has seldom explored the students’ entire EFL (English as a foreign language) learning process and mechanism from the perspective of learners within this model. This study therefore used the 3P (presage, process and product) teaching and learning theory to explore the mediating role of learning methods (i.e., learning engagement and academic procrastination) in the relationship between learning preparation (i.e., academic self-concept and course experience) and learning achievement within the Chinese EFL blended teaching context from the perspective of learners. In this study, 942 Chinese university students (male: N = 447; female: N = 495) participated in a survey and completed electronic questionnaires on EFL-related academic self-concept, learning engagement, academic procrastination, and learning achievement. The data were analyzed using AMOS software and a structural equation modeling (SEM) technique. The results showed that both students’ academic self-concept and course experience directly and positively predicted their English learning achievement. Moreover, students’ academic self-concept of learning achievement was partially mediated by learning engagement and academic procrastination, whereas the effect of course experience on learning achievement was fully mediated by learning engagement and academic procrastination. After discussing these findings, suggestions as well as limitations for future studies will be given.

by Perica Davitkov, Kyle Hoffman, Yngve Falck-Ytter, Brigid Wilson, Gjorgje Stojadinovikj, Donald D. Anthony, Stanley Martin Cohen, Gregory CooperBackground & aims Both non-alcoholic fatty liver disease (NAFLD) and hepatitis C virus (HCV) infection commonly result in hepatic fibrosis and may lead to cirrhosis. This study aims to determine the incidence of HCC in patients with HCV or NAFLD complicated by advanced fibrosis, inferred from measurements of liver stiffness. Methods Using Veterans Affairs (VA) Informatics and Computing Infrastructure (VINCI), we identified a nationwide cohort of patients with an existing diagnosis of HCV or NAFLD with liver transient elastography (TE) testing from 2015 to 2019. HCC cases, along with a random sample of non-HCC patients, were identified and validated, leading to calculation of incidence rates for HCC after adjustment for confounders. Results 26,161 patients carried a diagnosis of HCV and 13,629 were diagnosed with NAFLD at the time of testing. In those with HCV, rates of HCC increased with liver stiffness with incidences of 0.28 (95% CI 0.24, 0.34), 0.93 (95% CI 0.72, 1.17), 1.28 (95% CI 0.89, 1.79), and 2.79 (95% CI 2.47, 3.14)/100,000 person years for TE score ranges 14.5 kPa, respectively, after a median follow-up of 2.3 years. HCC incidence also increased with higher TE liver stiffness measures in NAFLD after a median follow-up of 1.1 years. Conclusion In this retrospective cohort, the incidence of HCC in HCV and NAFLD increases with higher TE liver stiffness measures, confirming that advanced fibrosis portends risk in viral and non-viral fibrotic liver diseases. Additional comparative studies are needed to determine the optimal cut point of TE liver stiffness to inform HCC screening guidelines and approaches.…

by Apichaya Sriwarom, Direkrit Chiewchengchol, Supichcha Saithong, Navaporn Worasilchai, Ariya ChindampornNeutrophils are innate immune cells that play crucial roles in response to extracellular pathogens, including bacteria and fungi. Pythium insidiosum (P insidiosum) is a fungus-like pathogen that causes 'pythiosis' in mammals. This study investigated in vitro function of human neutrophils against P. insidiosum. We demonstrated the killing mechanism of neutrophils when incubated with P. insidiosum zoospores (infective stage), such as phagocytosis and neutrophil extracellular traps (NETs). Healthy human neutrophils significantly reduced six strains of live zoospores isolated from different sources compared to the condition without neutrophils (p < 0.001), observed by colony count and trypan blue staining. As our results showed the killing ability of neutrophils, we further investigated the neutrophil killing mechanism when incubating with zoospores. Our study found that only two strains of heat-killed zoospores significantly induced phagocytosis (p < 0.01). Co-culture of heat-killed zoospores and neutrophils demonstrated NET formation, which was detected by immunofluorescence staining using DAPI, anti-myeloperoxidase, and anti-neutrophil elastase and quantitated under the fluorescence microscope. In addition, the level of cell-free DNA released from neutrophils (as a marker of NET production) after incubation with zoospores showed significantly increased levels when compared with unstimulated neutrophils (p < 0.001). Our findings demonstrate that neutrophils revealed the NET formation in response to P. insidiosum zoospores. This study is the first observation of the neutrophil mechanism against P. insidiosum, which could provide a better understanding of some parts of the innate immune response during pythiosis.

by Karina Dahl Steffensen, Dorte Gilså Hansen, Kurt Espersen, Susanne Lauth, Peter Fosgrau, Anders Meinert Pedersen, Peter Sigerseth Groen, Christian Sauvr, Karina OllingBackground Shared decision making (SDM) is a core element in the meeting between patient and healthcare professionals, but has proved difficult to implement and sustain in routine clinical practice. One of five Danish regions set out to succeed and to develop a model that ensures lasting SDM based on learnings from large-scale real-world implementation initiatives that go beyond the ’barriers’ and ’facilitators’ research approach. This paper describes this process and development of a generic implementation model, SDM:HOSP. Methods This project was carried out in the Region of Southern Denmark with five major hospital units. Based on existing theory of SDM, SDM implementation, implementation science and improvement methodology, a process of four phases were described; development of conceptual elements, field-testing, evaluation, and development of the final implementation model. The conceptual elements developed aimed to prepare leaders, train SDM teachers, teach clinicians to perform SDM, support development of patient decision aids, and support systematic planning, execution and follow-up. Field testing was done including continuous participant evaluations and an overall evaluation after one year. Results Data from field testing and learnings from the implementation process, illustrated the need for a dynamic and easy adjustable model. The final SDM:HOSP model included four themes; i)Training of Leaders, ii) Training of Teachers and Clinicians, iii) Decision Helper, and iv) ‘Process’, each with details in three levels, 1) shared elements, 2) recommendations, and 3) local adaption. Conclusions A feasible and acceptable model for implementation of SDM across hospitals and departments that accounts for different organizations and cultures was developed. The overall design can easily be adapted to other organizations and can be adjusted to fit the specific organization and culture. The results from the ongoing and overall evaluation suggest promising avenues for future work in further testing and research of the usability of the model.…

The Ortho VITROS SARS-CoV-2 spike-specific quantitative IgG (VITROS S-IgG) assay has been developed to assess neutralizing antibody (NT antibody) against SARS-CoV-2 spike (S) antibodies. However, it has not been evaluated in Japan, where the total cases and death toll are lower than the rest of the world. Methods The clinical performance of VITROS S-IgG was evaluated by comparing with the NT antibody levels measured by the surrogate virus neutralizing antibody test (sVNT). A total of 332 serum samples from 188 individuals were used. Of these, 219 samples were from 75 COVID-19 patients: 96 samples from 20 severe/critical cases (Group S), and 123 samples from 55 mild/moderate cases (Group M). The remaining 113 samples were from 113 healthcare workers who had received 2 doses of the BNT162b2 vaccine. Results VITROS S-IgG showed good correlation with the cPass sVNT assay (Spearman rho = 0.91). Both VITROS S-IgG and cPass sVNT showed significantly higher plateau levels of antibodies in Group S compared to Group M. Regarding the humoral immune responses after BNT162b2 vaccination, individuals who were negative for SARS-CoV-2 nucleocapsid (N)-specific antibodies had statistically lower titers of both S-IgG and sVNT compared to individuals with a history of COVID-19 and individuals who were positive for N-specific antibodies without history of COVID-19. In individuals who were positive for N-specific antibodies, S-IgG and sVNT titers were similar to individuals with a history of COVID-19. Conclusions Although the automated quantitative immunoassay VITROS S-IgG showed a reasonable correlation with sVNT antibodies, there is some discrepancy between Vitros S-IgG and cPass sVNT in milder cases. Thus, VITROS S-IgG can be a useful diagnostic tool in assessing the immune responses to vaccination and herd immunity. However, careful analysis is necessary to interpret the results.…

The aim of the study was to characterize acute pediatric infectious fevers (APIF) in the pediatric department of the Douala Laquintinie Hospital. A cross-sectional study was conducted among children aged 2 months to 15 years who were admitted with an acute fever (anal temperature ≥ 37.5°C less than 5 days in infants and 7 days in adolescents). 200 children were included and followed up during their hospitalization. The mean age was 3.7 (IQ25-75: 1–4.6) years. More than 3 out of 5 patients (62.5%) came from another health facility and anemia accounted for 29% of the reasons for consultation associated with fever. The main symptoms were vomiting (28%), cough (26%), convulsions (21%) and diarrhea (20%). Skin-mucosal pallor (43.0%) and hepatosplenomegaly (26.0%) were the most common physical signs encountered. Among febrile children, 116/200 (58%) were infected with at least 1 pathogen, and 1/200 (0.5%) had a fever of unknown etiology. Malaria (53% vs 80.5% presumptive) associated with anemia (95.3% of cases) was the most common pathology associated with APIF, followed by pneumonia (19.5%), meningitis (11.5%) and urinary tract infections (10% vs 54.5% presumptive). Malaria was over-diagnosed on admission and over-treated as well as urinary tract infection. A better understanding of common pathogens carriage, a better capacity for improved diagnosis and a better applied clinical algorithm for febrile illnesses in children are needed.

Abstract Purpose The severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) has caused substantial mortality worldwide. We investigated clinical and demographic features of COVID-19-related deaths that occurred between March 2020 and January 2022 in Regensburg, Germany. Methods We compared data across four consecutive time periods: March 2020 to September 2020 (period 1), October 2020 to February 2021 (period 2), March 2021 to August 2021 (period 3), and September 2021 to January 2022 (period 4). Results Overall, 405 deaths in relation to COVID-19 were reported. The raw case fatality ratio (CFR) was 0.92. In periods 1 to 4, the CFRs were 1.70%, 2.67%, 1.06%, and 0.36%. The age-specific CFR and mortality were highest in persons aged ≥ 80 years in period 2 while mortality in younger cases increased with time. The median age at death was 84 years and it varied slightly across periods. Around 50% of cases of death were previously hospitalized. In all time periods, the cause of death was mostly attributed to COVID-19. Over the four periods, we did not find significant changes in the distribution of sex and risk factors for severe disease. The most frequent risk factor was cardio-circulatory disease. Conclusion In conclusion, the CFR decreased over time, most prominently for period 4. Mortality was considerable and younger cases were increasingly at risk. …

This study aimed to investigate the factors associated with maintenance of viral suppression after antiretroviral therapy (ART) discontinuation.

From December 30, 2019, to May 14, 2022, 517,648,631 people were infected with coronavirus disease 2019 (COVID-19), and 6,261,708 people died in total. The male-to-female ratio was 0.9 among infected people and 1.29 in deceased people [1]. According to the U.S. Centers for Disease Control and Prevention (CDC, https://www.cdc.gov/, last accessed 05/09/22), 207,793 pregnant women in the United States were infected, and 296 died.

Abstract Background and aims Liver-associated complications still frequently lead to mortality in people with HIV (PWH), even though combined antiretroviral treatment (cART) has significantly improved overall survival. The quantification of circulating collagen fragments released during collagen formation and degradation correlate with the turnover of extracellular matrix (ECM) in liver disease. Here, we analysed the levels of ECM turnover markers PC3X, PRO-C5, and PRO-C6 in PWH and correlated these with hepatic fibrosis and steatosis. Methods This monocentre, retrospective study included 141 PWH. Liver stiffness and liver fat content were determined using transient elastography (Fibroscan) with integrated CAP function. Serum levels of formation of cross-linked type III collagen (PC3X), formation of type V collagen (PRO-C5) and formation type VI collagen (PRO-C6), also known as the hormone endotrophin, were measured with ELISA. Results Twenty-five (17.7%) of 141 PWH had clinical significant fibrosis with liver stiffness ≥ 7.1 kPa, and 62 PWH (44.0%) had steatosis with a CAP value > 238 dB/m. Study participants with fibrosis were older (p = 0.004) and had higher levels of AST (p = 0.037) and lower number of thrombocytes compared to individuals without fibrosis (p = 0.0001). PC3X and PRO-C6 were markedly elevated in PWH with fibrosis. Multivariable cox regression analysis confirmed PC3X as independently associated with hepatic fibrosis. PRO-C5 was significantly elevated in participants with presence of hepatic steatosis. Conclusion Serological levels of cross-linked type III collagen formation and endotrophin were significantly associated with liver fibrosis in PWH receiving cART and thus may be suitable as a non-invasive evaluation of liver fibrosis in HIV disease. …

Abstract Background Around the world, policymakers have clearly communicated that COVID-19 vaccination programs need to be accepted by a large proportion of the population to allow life return to normal. However, according to the Center for Disease Control, about 31% of the United States population had not completed the primary vaccination series as of November 2022. Aims The primary aim of this work is to identify the factors associated by American citizens with the decision to be vaccinated against COVID-19. In addition, the proportion of fatal events from COVID-19 vaccinations was estimated and compared with the data in the VAERS database. Methods An online survey of COVID-19 health experiences was conducted. Information was collected regarding reasons for and against COVID-19 inoculations, experiences with COVID-19 illness and COVID-19 inoculations by survey respondents and their social circles. Logit regression analyses were carried out to identify factors influencing the likelihood of being vaccinated. Results A total of 2840 participants completed the survey between December 18 and 23, 2021. 51% (1383 of 2840) of the participants were female and the mean age was 47 (95% CI 46.36–47.64) years. Those who knew someone who experienced a health problem from COVID-19 were more likely to be vaccinated (OR: 1.309, 95% CI 1.094–1.566), while those who knew someone who experienced a health problem following vaccination were less likely to be vaccinated (OR: 0.567, 95% CI 0.461–0.698). 34% (959 of 2840) reported that they knew at least one person who had experienced a significant health problem due to the COVID-19 illness. Similarly, 22% (612 of 2840) of respondents indicated that they knew at least one person who had experienced a severe health problem following COVID-19 vaccination. With these survey data, the total number of fatalities due to COVID-19 inoculation may be as high as 278,000 (95% CI 217,330–332,608) when fatalities that may have occurred regardless of inoculation are removed. Conclusion Knowing someone who reported serious health issues either from COVID-19 or from COVID-19 vaccination are important factors for the decision to get vaccinated. The large difference in the possible number of fatalities due to COVID-19 vaccination that emerges from this survey and the available governmental data should be further investigated. …

Abstract Background Post-COronaVIrus Disease 2019 (COVID-19) conditions (PCC) include multiple symptoms afflicting different organs and systems. To evaluate the frequency and type of them, we described our multidisciplinary approach with preliminary results of the first enrolled patients. Methods We included patients aged ≥ 18 years with hospital admission for confirmed SARS-CoV-2 infection. Symptoms were grouped in five macro groups hereafter referred to as "Symptoms Category" (SC): respiratory SC (dyspnoea or cough), neurological SC (peripheral neuropathies, headache, impaired mobility, behavioural disorders), psychological SC (sleep disorders, mood disorders), muscular SC (arthromyalgia, asthenia), other SC (fever, alopecia, diarrhoea, weight loss, smell and taste alterations, sexual dysfunctions). SC were evaluated at discharge and at follow-up. Association between patients’ characteristics and presence of SC at follow up was estimated by a logistic multivariable regression model. Results From June 2020 to July 2021, we followed up 361 patients: 128 (35.5%) who were previously admitted to Intensive Care Unit (ICU) and 233 patients to ordinary department. The median length of hospital stay was 20 days (Inter-Quartile-Range 13–32). Most patients (317/361, 87.8%) were still symptomatic at discharge, with one third referring three or more SC. At follow up, 67.3% (243/361) of patients still complained at least one SC. Moreover, 159 patients (44%) developed at least one new involved SC during follow up: 116 (72.9%) one SC, 39 (24.5%) two SC, 4 (2.5%) three or more SC. At follow up visit 130 of 361 (36%) were still with SC developed during follow up. At multivariable analysis presence of any SC at follow-up was associated with male gender (Odds Ratio [OR] 3.23, Confidence Interval [CI] 95% 1.46–7.15), ICU admission (OR 2.78, CI 95% 1.29–5.96) and presence of SC at discharge (OR 14.39, CI 95% 6.41–32.32). Conclusions In our sample of patients with severe COVID-19, we found that PCC are highly variable and fluctuating over time; in particular, in about 50% of our patients new SC appear during follow up. Moreover, presence of PCC also in patients without SC at discharge and the variability of symptoms underlining the advisability of our multidisciplinary approach.

Abstract Background Nannizziopsis is a genus of fungi with several known cases in reptiles of pyogranulomatous infections at cutaneous and musculoskeletal level, of rapid and fatal evolution. There are few cases of this genus described in humans, mainly skin affection but also with visceral abcesses, typically in immunosuppressed patients, with a recent visit to Africa. Case presentation A 45-year-old woman immunosuppressed after renal transplantation and with a recent visit to Nigeria presented with a painless breast abcess, ulceration to the skin and bleeding, and non hematic telorrhea. The mammogram, also completed with an ultrasound scan, showed a polylobulated nodule, BI-RADS 4C. Due to the suspicion of breast cancer, a core needle biopsy was performed and the pathology study showed abundant presence of fungal spores and hyphae. It was identified by genomic amplification of the internal transcription spacer region-2 and a percentage of similarity with sequences of Nannizziopsis obscura from GenBank of 98% was obtained. An empiric treatment with anidulafungin was initiated, and after the surgical resection, it was replaced by isavuconazole, with a total time of treatment of one month. Conclusions This is the first case report of a successful treatment of Nannizziopsis obscura with isavuconazole, with the shortest time of treatment published for this fungi. We highlighted the importance of referring difficult to diagnose species to reference centers, as well as achieving the most complete resection in order to shorten the antibiotic therapy. …

Abstract Background The effect of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) on mortality was preliminarily explored through the comparison of ACEIs/ARBs with non-ACEIs/ARBs in patients with coronavirus disease 2019 (COVID-19). Reaching a conclusion on whether previous ACEI/ARB treatment should be continued in view of the different ACE2 levels in the comparison groups was not unimpeachable. Therefore, this study aimed to further elucidate the effect of ACEI/ARB continuation on hospital mortality, intensive care unit (ICU) admission, and invasive mechanical ventilation (IMV) in the same patient population. Methods We searched PubMed, the Cochrane Library, Ovid, and Embase for relevant articles published between December 1, 2019 and April 30, 2022. Continuation of ACEI/ARB use after hospitalization due to COVID-19 was considered as an exposure and discontinuation of ACEI/ARB considered as a control. The primary outcome was hospital mortality, and the secondary outcomes included 30-day mortality, rate of ICU admission, IMV, and other clinical outcomes. Results Seven observational studies and four randomized controlled trials involving 2823 patients were included. The pooled hospital mortality in the continuation group (13.04%, 158/1212) was significantly lower than that (22.15%, 278/1255) in the discontinuation group (risk ratio [RR] = 0.45; 95% confidence interval [CI], 0.28–0.72; P = 0.001). Continuation of ACEI/ARB use was associated with lower rates of ICU admission (10.5% versus 16.2%, RR = 0.63; 95% CI 0.5–0.79; P < 0.0001) and IMV (8.2% versus 12.5%, RR = 0.62; 95% CI 0.46–0.83, P = 0.001). Nevertheless, the effect was mainly demonstrated in the observational study subgroup (P < 0.05). Continuing ACEI/ARB had no significant effect on 30-day mortality (P = 0.34), acute myocardial infarction (P = 0.08), heart failure (P = 0.82), and acute kidney injury after hospitalization (P = 0.98). Conclusion Previous ACEI/ARB treatment could be continued since it was associated with lower hospital deaths, ICU admission, and IMV in patients with COVID-19, although the benefits of continuing use were mainly shown in observational studies. More evidence from multicenter RCTs are still needed to increase the robustness of the data. Trial registration PROSPERO (CRD42022341169). Registered 27 June 2022 …

Abstract Background Increased folic acid has been found to be latently protective against gynecological infection, including several kinds of vaginosis. In this study, we laid emphasis on whether RBC (Red Blood Cell) folate was associated with the infectious ratio of Trichomonas vaginalis, a kind of anaerobic parasitic protozoan. Methods We set RBC folate as the exposure variable and Trichomonas vaginalis as the outcome variable. Other subsidiary variables were regarded as covariates that may work as potential effect modifiers. The cross-sectional study was conducted with two merged waves of the National Health and Nutrition Examination Survey (NHANES) from 2001 to 2004, and a sample of 1274 eligible women (1212 negative and 62 positive in Trichomonas vaginalis infection) was integrated for the exploration of the association between RBC folate and Trichomonas vaginalis infection. Multivariate regression analyses, subgroup analyses, and subsequent smooth curve fittings were conducted to estimate the relationship between RBC folate and Trichomonas vaginalis in women. Results In the multivariable logistic regression analyses, a negative association was observed between stratified RBC folate status and Trichomonas vaginalis infection with all confounders adjusted. Referencing the lowest RBC folate concentration quartile, the higher concentration quartiles reported a relatively lower infection ratio, while there was a weak correlation between total RBC folate concentration and T. vaginalis (Trichomonas vaginalis) infection. In subgroup analyses stratified by BMI and age, this association was only found significant in high age and BMI groups. Conclusions The cross-sectional study indicated a negative association between RBC folic acid and Trichomonas vaginalis infection, and latent effects of BMI and age on the association were also found. …

Abstract Introduction Sexually transmitted infections (STIs) are the major public health problem globally, affecting millions of people every day. The burden is high in the Sub-Saharan region, including Ethiopia. Besides, there is little evidence on the distribution of STIs across Ethiopian regions. Hence, having a better understanding of the infections is of great importance to lessen their burden on society. Therefore, this article aimed to assess predictors of STIs using machine learning techniques and their geographic distribution across Ethiopian regions. Assessing the predictors of STIs and their spatial distribution could help policymakers to understand the problems better and design interventions accordingly. Methods A community-based cross-sectional study was conducted from January 18, 2016, to June 27, 2016, using the 2016 Ethiopian Demography and Health Survey (EDHS) dataset. We applied spatial autocorrelation analysis using Global Moran’s I statistics to detect latent STI clusters. Spatial scan statics was done to identify local significant clusters based on the Bernoulli model using the SaTScan™ for spatial distribution and Supervised machine learning models such as C5.0 Decision tree, Random Forest, Support Vector Machine, Naïve Bayes, and Logistic regression were applied to the 2016 EDHS dataset for STI prediction and their performances were analyzed. Association rules were done using an unsupervised machine learning algorithm. Results The spatial distribution of STI in Ethiopia was clustered across the country with a global Moran’s index = 0.06 and p value = 0.04. The Random Forest algorithm was best for STI prediction with 69.48% balanced accuracy and 68.50% area under the curve. The random forest model showed that region, wealth, age category, educational level, age at first sex, working status, marital status, media access, alcohol drinking, chat chewing, and sex of the respondent were the top 11 predictors of STI in Ethiopia. Conclusion Applying random forest machine learning algorithm for STI prediction in Ethiopia is the proposed model to identify the predictors of STIs. …

Plants dynamically interact with the rhizosphere (see Glossary) and phyllosphere microbiomes. While most of these interactions can be perceived as neutral, specific plant–microbe associations are directly related to the amelioration of plant stresses imposed by diverse biotic and abiotic factors. Unlike animals, plants do not have a central nervous system. However, in an analogous manner, plants have a vascular system that connects roots and shoots and leaves through a complex network of long-distance signaling induced by the perception of biotic/abiotic environmental cues and/or by specific signals produced by plant-associated microbes.

Life expectancy in the US decreased by about a half year between 2020 and 2021, from 77 years to 76.4 years, according to final 2021 mortality data from the National Center for Health Statistics. Life expectancy in 2021 was at its lowest level since 1996. The report attributed the drop mainly to increased deaths from COVID-19 and drug overdoses.

The COVID-19 pandemic caught society unprepared. The lack of therapeutic agents for coronaviruses led to a scramble to investigate approved medications for repurposing against SARS-CoV-2. Successes were achieved with immunomodulatory agents for the inflammatory disease processes of COVID-19, but the antiviral search has been less productive. One of the more interesting therapeutic candidates investigated is fluvoxamine.

This randomized, placebo-controlled platform trial compares the use of low-dose fluvoxamine (50 mg twice daily) for 10 days compared with placebo in outpatients with mild to moderate COVID-19.

This study evaluates the adoption of clinician billing for patient portal messages as e-visits, prompted by significant increases in patient messaging after the onset of the COVID-19 pandemic.
