Efficacy of pulmonary surfactant with budesonide in premature infants: A systematic review and meta-analysis

Pulmonary surfactant (PS) is one of the main treatment for neonates with respiratory distress syndrome (RDS). Budesonide has recently been studied as an additional treatment in such cases, but there is limited evidence supporting this. This study was implemented to determine the efficacy of PS combined with budesonide in premature infants. To achieve this, we conducted a systematic review and meta-analysis of randomized controlled trials by searching PubMed, Scopus, Embase, and the Cochrane Library from inception until July 12, 2024. We utilized a random-effects model to calculate the risk ratio and mean differences (MDs) with 95% confidence intervals (CIs) for the clinical outcomes of PS with budesonide versus PS alone. We used the GRADE approach to assess the quality of the evidence. We included 26 randomized controlled trials with a total of 2701 patients in the analysis. Treatments of PS with budesonide and PS alone were compared in all trials. PS with budesonide reduced bronchopulmonary dysplasia (BPD) incidence (risk ratio, 0.61; 95% CI, 0.51, 0.73), duration of mechanical or invasive mechanical ventilation (MD, −2.21 days; 95% CI, −2.72, −1.71), duration requiring oxygen (MD, −5.86 days; 95% CI, −8.44, −3.29), and hospitalization time (MD, −5.61 days; 95% CI, −8.65, −2.56). These results were based on low to very low evidence certainty. Only moderate-to-severe BPD or severe BPD showed a significant reduction when PS was used in conjunction with budesonide, a finding supported by moderate evidence certainty. Our study showed that the administration of PS with budesonide significantly improved respiratory outcomes, including the incidence of BPD, duration of mechanical or invasive mechanical ventilation, duration requiring oxygen, and hospitalization time in preterm infants, without short-term adverse drug events. However, the evidence certainty was mostly low to very low.

DigiLoCS: A leap forward in predictive organ-on-chip simulations

Digital twins, driven by data and mathematical modelling, have emerged as powerful tools for simulating complex biological systems. In this work, we focus on modelling the clearance on a liver-on-chip as a digital twin that closely mimics the clearance functionality of the human liver. Our approach involves the creation of a compartmental physiological model of the liver using ordinary differential equations (ODEs) to estimate pharmacokinetic (PK) parameters related to on-chip liver clearance. The objectives of this study were twofold: first, to predict human clearance values, and second, to propose a framework for bridging the gap between in vitro findings and their clinical relevance. The methodology integrated quantitative Organ-on-Chip (OoC) and cell-based assay analyses of drug depletion kinetics and is further enhanced by incorporating an OoC-digital twin model to simulate drug depletion kinetics in humans. The in vitro liver clearance for 32 drugs was predicted using a digital-twin model of the liver-on-chip and in vitro to in vivo extrapolation (IVIVE) was assessed using time series PK data. Three ODEs in the model define the drug concentrations in media, interstitium and intracellular compartments based on biological, hardware, and physicochemical information. A key issue in determining liver clearance appears to be the insufficient drug concentration within the intracellular compartment. The digital twin establishes a connection between the hardware chip structure and an advanced mapping of the underlying biology, specifically focusing on the intracellular compartment. Our modelling offers the following benefits: i ) better prediction of intrinsic liver clearance of drugs compared to the conventional model and ii )explainability of behaviour based on physiological parameters. Finally, we illustrate the clinical significance of this approach by applying the findings to humans, utilising propranolol as a proof-of-concept example. This study stands out as the biggest cross-organ-on-chip platform investigation to date, systematically analysing and predicting human clearance values using data obtained from various in vitro liver-on-chip systems. Accurate prediction of in vivo clearance from in vitro data is important as inadequate understanding of the clearance of a compound can lead to unexpected and undesirable outcomes in clinical trials, ranging from underdosing to toxicity. Physiologically based pharmacokinetic (PBPK) model estimation of liver clearance is explored. The aim is to develop digital twins capable of determining better predictions of clinical outcomes, ultimately reducing the time, cost, and patient burden associated with drug development. Various hepatic in vitro systems are compared and their effectiveness for predicting human clearance is investigated. The developed tool, DigiLoCs, focuses explicitly on accurately describing complex biological processes within liver-chip systems. ODE-constrained optimisation is applied to estimate the clearance of compounds. DigiLoCs enable differentiation between active biological processes (metabolism) and passive processes (permeability and partitioning) by incorporating detailed information on compound-specific characteristics and hardware-specific data. These findings signify a significant stride towards more accurate and efficient drug development methodologies.

Charge-transfer complexation of coordination cages for enhanced photochromism and photocatalysis

AbstractIntensified host-guest electronic interplay within stable metal-organic cages (MOCs) presents great opportunities for applications in stimuli response and photocatalysis. Zr-MOCs represent a type of robust discrete hosts for such a design, but their host-guest chemistry in solution is hampered by the limited solubility. Here, by using pyridinium-derived cationic ligands with tetrakis(3,5-bis(trifluoromethyl)phenyl)borate (BArF−) as solubilizing counteranions, we report the preparation of soluble Zr-MOCs of different shapes (1-4) that are otherwise inaccessible through a conventional method. Enforced arrangement of the multiple electron-deficient pyridinium groups into one cage (1) leads to magnified positive electrostatic field and electron-accepting strength in favor of hosting electron-donating anions, including halides and tetraarylborates. The strong charge-transfer (CT) interactions activate guest-to-host photoinduced electron transfer (PET), leading to pronounced and regulable photochromisms. Both ground-state and radical structures of host and host-guest complexes have been unambiguously characterized by X-ray crystallography. The CT-enhanced PET also enables the use of 1 as an efficient photocatalyst for aerobic oxidation of tetraarylborates into biaryls and phenols. This work presents the solution assembly of soluble Zr-MOCs from cationic ligands with the assistance of solubilizing anions and highlights the great potential of harnessing host-guest CT for boosting PET-based functions and applications.

Regional disparities of full pentavalent vaccine uptake and the determinants in Ethiopia: Mapping and spatial analysis using the EDHS data

Background The full pentavalent (DPT-HepB-Hib) vaccination is the main strategy to prevent five communicable diseases in early childhood, especially in countries with huge communicable disease burdens like Ethiopia. Exploring spatial distributions and determinants of full pentavalent vaccination status in minor ecological areas in Ethiopia is crucial for creating targeted immunization campaigns and monitoring the advancement of accomplishing sustainable development goals. This study aimed to investigate the spatial disparities and determinants of full pentavalent vaccination among 12-23-month-old children in Ethiopia. Method The data on pentavalent vaccine uptake was found in the Ethiopian Health and Demographic Survey (EDHS, 2019). A two-stage cluster sampling method was applied to collect the EDHS data. The enumeration area was the primary sample unit while the household served as the secondary sampling unit. The geographical variations of full pentavalent vaccine uptake were explored using Quantum Geographic Information System (QGIS) software. The significant predictors of full pentavalent vaccination were identified using a simple logistic regression model through R version 4.1 software. Result The national full pentavalent vaccine uptake was 59.2%. The spatial distribution of full pentavalent vaccine uptake was not uniform in Ethiopia. Spatial cluster analysis revealed that most of low coverage regions for full pentavalent vaccine uptake were Afar, Somali, and Harari. The regions with the highest and lowest rates of vaccine uptake were Tigray and Harari region, respectively. Maternal age of 35–49 years (AOR = 3.42; 95% CI: 1.99, 5.87), and 25–34 years (AOR = 1.55; 95% CI: 1.17, 2.19), primary education attended (AOR = 1.51; 95%CI: 1.07, 2.11), richness wealth index (AOR = 1.96; 95% CI: 1.40, 2.75), birth order of 1–3 (AOR = 1.88; 95% CI: 1.19, 2.96), and delivery in the health facility (AOR = 3.41: 95% CI: 2.52, 4.61) were the determinants of full pentavalent vaccine uptake in Ethiopia. Conclusion Ethiopia’s full pentavalent vaccine uptake was far lower than the global target. Older maternal age, maternal education, wealth index, birth order, and giving birth in a health facility were the determinants of full pentavalent vaccine uptake. Special attention should be given to Afar, Somali, and Harari regions, to strengthen the vaccine uptake. Moreover, improved socioeconomic status and getting maternal health services during delivery are necessary to enhance vaccine uptake.

Spatial control of doping in conducting polymers enables complementary, conformable, implantable internal ion-gated organic electrochemical transistors

Abstract Complementary transistors are critical for circuits with compatible input/output signal dynamic range and polarity. Organic electronics offer biocompatibility and conformability; however, generation of complementary organic transistors requires introduction of separate materials with inadequate stability and potential for tissue toxicity, limiting their use in biomedical applications. Here, we discovered that introduction of source/drain contact asymmetry enables spatial control of de/doping and creation of single-material complementary organic transistors from a variety of conducting polymers of both carrier types. When integrated with the vertical channel design and internal ion reservoirs of internal ion-gated organic electrochemical transistors, we produced matched complementary IGTs (cIGTs) that formed high-performance conformable amplifiers with 200 V/V uniform gain and 2 MHz bandwidth. These amplifiers showed long-term in vivo stability, and their miniaturized biocompatible design allowed implantation in developing rodents to monitor network maturation. cIGTs expand the use of organic electronics in standard circuit designs and enhance their biomedical potential.

Water, sanitation, handwashing, and nutritional interventions can reduce child antibiotic use: evidence from Bangladesh and Kenya

AbstractAntibiotics can trigger antimicrobial resistance and microbiome alterations. Reducing pathogen exposure and undernutrition can reduce infections and antibiotic use. We assess effects of water, sanitation, handwashing (WSH) and nutrition interventions on caregiver-reported antibiotic use in Bangladesh and Kenya, longitudinally measured at three timepoints among birth cohorts (ages 3–28 months) in a cluster-randomized trial. Over 50% of children used antibiotics at least once in the 90 days preceding data collection. In Bangladesh, the prevalence of antibiotic use was 10–14% lower in groups receiving WSH (prevalence ratio [PR] = 0.90 (0.82–0.99)), nutrition (PR = 0.86 (0.78–0.94)), and nutrition+WSH (PR = 0.86 (0.79–0.93)) interventions. The prevalence of using antibiotics multiple times was 26–35% lower in intervention arms. Reductions were largest when the birth cohort was younger. In Kenya, interventions did not affect antibiotic use. In this work, we show that improving WSH and nutrition can reduce antibiotic use. Studies should assess whether such reductions translate to reduced antimicrobial resistance.

Like milk on the stove: Healthcare professionals navigating uncertainty when caring for families with 22q11DS

Introduction 22q11 deletion syndrome (22q11DS) results from a microdeletion on chromosome 22 and is the most common microdeletion disorder in humans, affecting 1 in 2148 live births. Clinical manifestations vary widely among individuals and across different life stages. Effective management requires the involvement of a specialized multidisciplinary team. This study aims to explore the experiences of healthcare professionals in caring for the families of children with 22q11DS, focusing on their challenges, rewards, and coping strategies. Methods Data for this interview study were collected as part of a broader mixed methods research project aimed at enhancing the psychosocial well-being of children aged 3–15 years with 22q11DS and their families. The qualitative aspect of this study focused on capturing the experiences of healthcare professionals involved in their care, recruited purposively through collaborators and snowball sampling methods. Reflexive thematic analysis of semi-structured interviews was performed after verbatim transcription. Results Twenty healthcare providers from different specialties were interviewed. The majority had a working experience of more than 10 years and were part of a 22q11DS clinic. After data analysis, four themes (and many sub-themes) were identified that were all related to the topic of uncertainty: acknowledging uncertainty, sharing uncertainty, acting on uncertainty and coping with uncertainty. Many experts showed a sense of humbleness when caring for the families and most of the participants emphasized the role of peer support and multidisciplinary teams. Conclusion Our study reveals how healthcare professionals manage the uncertainty associated with 22q11DS, highlighting the importance of peer support and multidisciplinary team collaboration. Providers recognize the limits of their medical expertise and value the perspectives of families living with the condition. Their coping strategies play a critical role in handling uncertainty and suggest a need for further emphasis in the literature on the experiences of healthcare professionals dealing with rare diseases.

The impact of recognition, fairness, and leadership on employee outcomes: A large-scale multi-group analysis

In the dynamic field of organizational behavior, comprehending the determinants of employee engagement, burnout, and job satisfaction is pivotal. This research investigates the influence of various workplace factors, such as recognition, fairness, leadership, and workload, on these key employee outcomes. Utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM) for analysis, the study examines data from 25,285 employees. The results indicate that recognition significantly boosts employee engagement, while fairness and involvement also positively contribute, albeit to a lesser extent. Transformational leadership plays a dual role, enhancing engagement and reducing burnout. Notably, workload overload presents a nuanced impact, affecting both engagement and burnout. The study additionally reveals the detrimental effect of technological disruption anxiety on job satisfaction. A significant finding from the Multi-Group Analysis (MGA) is the varying impact of these factors between the private and public sectors, particularly in the context of transformational leadership’s effect on burnout and the differential influence of workload on burnout. These insights are critical for formulating effective organizational strategies and policies, highlighting the need for customized recognition initiatives, equitable management approaches, and well-balanced workload allocation.

Getting back on track after treatment of cancer: A qualitative interview study of cancer survivors’ experiences

Objective An increasing number of people resumes life after cancer treatment. Although the (long-term) side-effects of cancer and its treatment can be significant, less is known about the impact on cancer survivors’ participation in daily life. The aim of this study was to explore the common experiences of cancer survivors in resuming life after treatment. Methods A semi-structured interview study was conducted among 22 cancer survivors having a favorable prognosis after treatment. Purposive sampling was used to select a variable sample in terms of diagnoses (e.g. breast cancer, colorectal cancer, melanoma), age (18–77 years), and time after diagnosis (0–7 years). Interviews were audio-taped, transcribed verbatim and analyzed in a thorough thematic analysis. Results Four main themes were identified. First, cancer survivors reported an emotional fallout episode to often follow treatment, which was characterized by a loss of direction and control due to discontinuation of medical care, decreased support from healthcare professionals and their social network, and an emotional set back. Second, survivors experienced challenges with getting back on track such as the impact of impaired physical and cognitive functions, and challenges and uncertainty related to work and finances. Third, in coping with changes and regaining trust they tried to find a balance between dealing with patient stigma and fear of recurrence on the one hand, and maintaining a positive mindset on the other hand. Fourth, the disease often led to re-evaluating values in life, health and work, which included realizing and accepting change and having a more conscious outlook on life. Conclusion In resuming life after treatment, cancer survivors experience several challenges and changes in values in different life domains that extend beyond the specific diagnosis. To improve supportive care, healthcare professionals should focus on the (changed) individual needs and values of survivors in the domains considered relevant to them.

Curcumin modulated gut microbiota and alleviated renal fibrosis in 5/6 nephrectomy-induced chronic kidney disease rats

Increasing evidence suggests that dysbiosis of gut microbiota exacerbates chronic kidney disease (CKD) progression. Curcumin (CUR) has been reported to alleviate renal fibrosis in animal models of CKD. However, the relationship between CUR and gut microbiome in CKD remains unclear. This study aims to investigate the potential anti-renal fibrosis effects of CUR from the gut microbiota perspective. A 5/6 nephrectomy (5/6Nx) rat model was used to explore the therapeutic effect of CUR on renal fibrosis. Tight junction protein expression levels were measured to assess intestinal barrier function. 16S rRNA sequencing was employed to evaluate changes in gut microbiota composition, and metabolomics was utilized to detect alterations in plasma metabolites. The administration of CUR significantly ameliorated renal fibrosis and inhibited inflammation in 5/6Nx rats. Additionally, CUR markedly improved the expression of tight junction proteins and local colon inflammation. CUR also positively reconstructed gut microbiota, significantly increasing the abundance of beneficial bacteria, such as Lachnospiraceae_NK4A136_group, Eubacterium_siraeum_group, and Muribaculaceae was significantly increased. Metabolomics revealed that CUR reduced uremic retention solutes and elevated Vitamin D and short-chain fatty acids (SCFAs). Spearman correlation analysis indicated that gut genera enriched by CUR were positively correlated with Vitamin D and SCFA and negatively correlated with chronic renal injury biomarkers. Mechanistically, we found inhibition of the LPS/TLR4/NF-κB and TGF-β1/Smads pathway in CUR-treated rats. Our study indicates that CUR has the potential to modulate gut microbiota composition, and that this modulation may contribute to the anti-fibrosis effects of CUR.

Evaluation and adaptation of a two-way text messaging intervention in the WIC breastfeeding peer counseling program: A qualitative analysis

Breastfeeding (BF) is vital for maternal and infant health, yet post-hospital discharge support remains a challenge. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides BF peer counseling prenatally and up to 1-year postpartum among low-income women in the United States. The Lactation Advice Through Texting Can Help (LATCH) intervention is an evidence-based two-way text messaging intervention that provides BF education and support in the WIC peer counseling program. The intervention is implemented by peer counselors (PCs) in the WIC program, with the supervision and support of a lactation consultant. The aim of this qualitative study was to assess the barriers and facilitators to the implementation of LATCH during the feasibility trial and to investigate strategies for adapting and scaling up the intervention. In-depth interviews with LATCH and PC program key informants aimed to evaluate the intervention and explore its adaptation and scale-up. Interviews were analyzed using line by line inductive thematic analysis. Findings were mapped to the Model for Adaptation Design and Impact (MADI) framework to describe the proposed adaptations, and to the Program Impact Pathways (PIP) framework to identify causal pathways and critical quality control points. Results demonstrate that LATCH facilitates continued engagement between PCs and WIC mothers; however, implementation feasibility issues remain. Suggested adaptations to LATCH include the use of an integrated comprehensive platform, ensuring continuity of care through an expanded spectrum of communication options, the need to develop a PC support model for “off hours” (non-business hours), and the need to obtain local WIC office management’s buy-in for the communications platform and the off-hours PC model. Critical quality control points were identified when results were mapped to the MADI and PIP frameworks. Implementing these changes has the potential to expand access to BF peer counseling support and improve BF equity among low-income women.

LFA-1: A potential key player in microglia-mediated neuroprotection against oxygen-glucose deprivation in vitro

For the last 38 years, all neuroprotective agents for patients with ischemic stroke have failed in clinical trials. The innate immune system, particularly microglia, is a much-discussed target for neuroprotective agents. Promising results for neuroprotection by inhibition of integrins with drugs such as natalizumab in animal stroke models have not been translated into clinical practice. Our present study reveals the relevance of a β2 integrin, lymphocyte function-associated antigen-1 (LFA-1), as a potential key player in protecting neuronal cell death after oxygen-glucose deprivation in organotypic hippocampal cell cultures. In addition, we identified microglial cells as effector cells for LFA-1-mediated neuroprotection. The counterpart of LFA-1 on microglia is unclear, but we show strong expression of ICAM-5 in hippocampal neurons, suggesting a critical role for direct crosstalk between microglia and neurons for neuronal survival under oxygen-glucose deprivation. The enigma of neuroprotection after ischemic stroke remains to be solved, and our findings highlight the continuing importance and lack of understanding of integrin-mediated pathways after ischemic stroke and the need for further intensive research.
