Development and evaluation of scenario-based e-simulation for humanitarian health training: a mixed-methods action research study.

OBJECTIVES: This study aimed to develop and evaluate a scenario-based e-simulation (SBES) to address the limited avilability of accessible and practical training for humanitarian public health responders. The objectives included SBES customisation, effectiveness evaluation, and identifying learning-enhancing design elements. DESIGN: A university-based, mixed-methods action research design. SETTING: The study was conducted at an international university's academic centre in Italy, and at a university-based master's programme in Yemen. PARTICIPANTS: The study involved 20 multidisciplinary global health and education experts and 66 international medical and health sciences students. RESULTS: Between September 2020 and July 2022, four SBES modules were developed, implemented and evaluated using a rapid prototype model. The modules, which targeted health professionals new to or with limited experience in the humanitarian field, included health needs assessment, essential health services, communicable diseases and health system. Formative evaluation improved the design and implementation of the SBES, which was found to be effective in the summative evaluation, evident from positive student reactions (the overall mean satisfaction rate was 6.03 out of 7, 95% CI 5.95 to 6.47) and the significant improvement in knowledge scores (p<0.001, effect size: 1.179). The identified effective design of SBES includes overlapping elements among content, strategy and technology. Poor internet access was recognised as a potential barrier to delivering the training in the humanitarian context, highlighting the need to develop an offline version in the next phase. CONCLUSION: The developed SBES met the training needs of the academic institution involved. The study findings will contribute to advancing future SBES training initiatives for disaster medicine and global health. Further studies are recommended to evaluate and address the challenges associated with SBES implementation beyond the study setting.

Humanitarian health education and training state-of-the-art: a scoping review.

Introduction: In the past decade, humanitarian emergencies have been increasing, leading to an higher demand for humanitarian health professionalization. Education and training are critical for preparing these workers to provide effective care during crises. Understanding the current state-of-the-art in humanitarian health education is essential to inform research and development of future educational programs. This review surveys the peer-reviewed literature to provide insights into the current thinking in the field. Methods: A review was conducted in March 2023 and updated in May 2024 using PubMed, Web of Science, Scopus, and Education Resources Information Center databases for English-language peer-reviewed articles published since January 2013. The review followed the Joanna Briggs Institute methodology for scoping reviews and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Data were analyzed using qualitative content analysis and presented as a narrative descriptive summary. Results: After screening, 32 articles met the inclusion criteria. The themes of the selected articles focus on education and training frameworks, mapping, and programs. Despite the growing opportunities, most education and training programs are based in the Global North. The gaps identified include a lack of standardized curriculum or competency frameworks and evaluation frameworks to guide the development and evaluation of further standardized training programs. Interdisciplinary and collaborative partnerships, iterative design, and mixed teaching methods and modalities, including e-learning, facilitated successful training. However, logistical and technical constraints and the lack of standardized training frameworks were barriers to developing, implementing, and evaluating such training programs. Conclusion: This review provides an overview of the humanitarian health education trends over the last decade and identifies key areas for future educational development and research. The findings emphasize the importance of adapting interdisciplinary and collaborative partnerships and prioritizing the training of local staff through regional centers, local leadership, and accessible e-learning, including e-simulation. The review also highlights the need for continued research and evaluation of humanitarian health education and training programs with standardized metrics to evaluate training programs and identify areas for improvement. These steps will help ensure that humanitarian health professionals receive adequate training to provide effective healthcare in crisis situations.

Characteristics and treatment outcomes of malnutrition among infants aged less than 6 months in North-East Nigeria (2019-2022).

Recommendations for the management of malnutrition among infants aged less than 6 months (<6 m) are based on limited evidence. This study aimed to describe the characteristics, treatment outcomes and outcome-associated factors among malnourished infants <6 m admitted at Médecins Sans Frontières (MSF) inpatient and ambulatory therapeutic feeding centres (ITFC and ATFC) in North-East Nigeria, 2019-2022. We conducted a descriptive analysis of the cohorts and logistic regression to measure the association between two selected outcomes-inpatient mortality and defaulting from the ambulatory programme-and possible factors associated. In total, 940 infants <6 m were admitted at ITFC. Most of them presented severe acute malnutrition and comorbidities, with diarrhoea being the most frequent. On discharge, 13.3% (n = 125) of infants were cured, 72.9% (n = 684) stabilized (referred to ATFC), 6.5% (n = 61) left against medical advice and 4.2% (n = 39) died. The median length of hospital stay was 10 days [IQR 7-14]. A hospital stay shorter than 10 days was significantly associated with inpatient mortality (aOR = 12.51, 95% confidence interval [CI] = 3.72-42.11, p ≤ 0.01). Among 561 infants followed up at the ATFC, only 2.8% reported comorbidities. On discharge, 80.9% (n = 429) were cured, 16.2% (n = 86) defaulted and 1.1% (n = 6) died. Male sex (aOR = 1.94, 95% CI = 1.15-3.27, p = 0.01), internally displaced status (aOR = 1.70, 95% CI = 1.05-2.79, p = 0.03) and <-3 WLZ (aOR = 1.95, 95% CI = 1.05-3.63, p = 0.03) were significantly associated with programme defaulting. Stabilization and recovery rates among malnourished infants <6 m in the studied project align with acceptable standards in this humanitarian setting. Notable defaulting rates from outpatient care should be further explored.

Exploring differences in the utilization of the emergency department between migrant and non-migrant populations: a systematic review.

BACKGROUND: Migrants face several barriers when accessing care and tend to rely on emergency services to a greater extent than primary care. Comparing emergency department (ED) utilization by migrants and non-migrants can unveil inequalities affecting the migrant population and pave the way for public health strategies aimed at improving health outcomes. This systematic review aims to investigate differences in ED utilization between migrant and non-migrant populations to ultimately advance research on migrants' access to care and inform health policies addressing health inequalities. METHODS: A systematic literature search was conducted in March 2023 on the Pubmed, Scopus, and Web of Science databases. The included studies were limited to those relying on data collected from 2012 and written in English or Italian. Data extracted included information on the migrant population and the ED visit, the differences in ED utilization between migrants and non-migrants, and the challenges faced by migrants prior to, during, and after the ED visit. The findings of this systematic review are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. RESULTS: After full-text review, 23 articles met the inclusion criteria. All but one adopted a quantitative methodology. Some studies reported a higher frequency of ED visits among migrants, while others a higher frequency among non-migrants. Migrants tend to leave the hospital against medical advice more frequently than the native population and present at the ED without consulting a general practitioner (GP). They are also less likely to access the ED via ambulance. Admissions for ambulatory care-sensitive conditions, namely health conditions for which adequate, timely, and effective outpatient care can prevent hospitalization, were higher for migrants, while still being significant for the non-migrant population. CONCLUSIONS: The comparison between migrants' and non-migrants' utilization of the ED did not suggest a clear pattern. There is no consensus on whether migrants access EDs more or less than non-migrants and on whether migrants are hospitalized at a higher or lower extent. However, migrants tend to access EDs for less urgent conditions, lack a referral from a GP and access the ED as walk-ins more frequently. Migrants are also discharged against medical advice more often compared to non-migrants. Findings of this systematic review suggest that migrants' access to care is hindered by language barriers, poor insurance coverage, lack of entitlement to a GP, and lack of knowledge of the local healthcare system.

Intraoperative individualization of positive-end-expiratory pressure through electrical impedance tomography or esophageal pressure assessment: a systematic review and meta-analysis of randomized controlled trials.

PURPOSE: This systematic review of randomized-controlled trials (RCTs) with meta-analyses aimed to compare the effects on intraoperative arterial oxygen tension to inspired oxygen fraction ratio (PaO2/FiO2), exerted by positive end-expiratory pressure (PEEP) individualized trough electrical impedance tomography (EIT) or esophageal pressure (Pes) assessment (intervention) vs. PEEP not tailored on EIT or Pes (control), in patients undergoing abdominal or pelvic surgery with an open or laparoscopic/robotic approach. METHODS: PUBMED®, EMBASE®, and Cochrane Controlled Clinical trials register were searched for observational studies and RCTs from inception to the end of August 2022. Inclusion criteria were: RCTs comparing PEEP titrated on EIT/Pes assessment vs. PEEP not individualized on EIT/Pes and reporting intraoperative PaO2/FiO2. Two authors independently extracted data from the enrolled investigations. Data are reported as mean difference and 95% confidence interval (CI). RESULTS: Six RCTs were included for a total of 240 patients undergoing general anesthesia for surgery, of whom 117 subjects in the intervention group and 123 subjects in the control group. The intraoperative mean PaO2/FiO2 was 69.6 (95%CI 32.-106.4 ) mmHg higher in the intervention group as compared with the control group with 81.4% between-study heterogeneity (p < 0.01). However, at meta-regression, the between-study heterogeneity diminished to 44.96% when data were moderated for body mass index (estimate 3.45, 95%CI 0.78-6.11, p = 0.011). CONCLUSIONS: In patients undergoing abdominal or pelvic surgery with an open or laparoscopic/robotic approach, PEEP personalized by EIT or Pes allowed the achievement of a better intraoperative oxygenation compared to PEEP not individualized through EIT or Pes.

Factors causing emergency medical care overload during heatwaves: A Delphi study.

Heatwaves pose an important risk for population health and are associated with an increased demand for emergency care. To find factors causing such overload, an online Delphi study included 15 experts in emergency medicine, disaster medicine, or public health. One open-ended question was delivered in the first round. After content analysis, the obtained statements were sent to the experts in two rounds to be rated on a 7-point linear scale. Consensus was defined as a standard deviation ≤ 1.0. Thirty-one statements were obtained after content analysis. The experts agreed on 18 statements, mostly focusing on the input section of patient processing and identifying stakeholders, the population, and primary care as targets of potential interventions. Additional dedicated resources and bed capacity were deemed important as per throughput and output sections, respectively. These findings could be used in the future to implement and test solutions to increase emergency healthcare resilience during heatwaves and reduce disaster risk due to climatic change.

Use of Simulation in Full-Scale Exercises for Response to Disasters and Mass-Casualty Incidents: A Scoping Review.

Disasters or mass-casualty incidents are uncommon events. The use of simulation is an ideal training modality in full-scale exercises as it immerses the participants in a replication of the actual environment where they can respond to simulated casualties in accordance with existing protocols.The objective of this scoping review is to answer the research question: "How effective is simulation, as assessed in full-scale exercises, for response to disasters and mass-casualty incidents world-wide?" Studies on full-scale exercises, as defined in World Health Organization (WHO) simulation exercise toolbox, that were published in peer-reviewed journals using the English language from 2001 through 2021 were included. Twenty studies were included from searching PubMed, Embase, and Web of Science. Simulated casualties were the most common simulation modality. Using Kirkpatrick's levels of evaluation to synthesize the data, simulation was reported to be generally effective and mostly demonstrated at the levels of learning of individuals and/or systems, as well as reaction of individuals. Evaluations at levels of behavior and results were limited due to the uncommon nature of disasters and mass-casualty incidents. However, evaluation outcomes across the full-scale exercises were varied, leading to the inability to consolidate effectiveness of simulation into a single measure. It is recommended for best evidence-based practices for simulation to be adhered to in full-scale exercises so that the trainings could translate into better outcomes for casualties during an actual disaster or mass-casualty incident. In addition, the reporting of simulation use in full-scale exercises should be standardized using a framework, and the evaluation process should be rigorous so that effectiveness could be determined and compared across full-scale exercises.

Scenario-Based e-Simulation Design for Global Health Education: Theoretical Foundation and Practical Recommendations.

Electronic simulation (e-simulation)-particularly scenario-based e-simulation (SBES)-is an increasingly used, promising educational strategy for global health education that can address gaps in training access, effectiveness, and cost. However, there is little guidance for educators on how to develop an SBES, and guidance is lacking outside the clinical context. Moreover, literature on medical education rarely uses the theoretical basis for e-simulation design and development, including for SBES. Hence, we aim to differentiate and describe the concept, design elements, and theoretical basis of SBES with examples from different topics in global health. In addition to enhancing the understanding of the potential of SBES for global health education, this manuscript also provides practical recommendations for global health educators in designing and developing SBESs based on the existing literature and authors' experiences. Overall, this manuscript will be useful for global health educators as well as other medical educators seeking to develop an SBES for similar skill sets.

e-Learning Evaluation Framework and Tools for Global Health and Public Health Education: Protocol for a Scoping Review.

BACKGROUND: There has been a significant increase in the use of e-learning for global and public health education recently, especially following the COVID-19 pandemic. e-Learning holds the potential to offer equal opportunities, overcoming barriers like physical limitations and training costs. However, its effectiveness remains debated, with institutions unprepared for the sudden shift during the pandemic. To effectively evaluate the outcomes of e-learning, a standardized and rigorous approach is necessary. However, the existing literature on this subject often lacks standardized assessment tools and theoretical foundations, leading to ambiguity in the evaluation process. Consequently, it becomes imperative to identify a clear theoretical foundation and practical approach for evaluating global and public health e-learning outcomes. OBJECTIVE: This protocol for a scoping review aims to map the state of e-learning evaluation in global and public health education to determine the existing theoretical evaluation frameworks, methods, tools, and domains and the gaps in research and practice. METHODS: The scoping review will be conducted following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. The initial search was performed in PubMed, Education Resource Information Center, Web of Science, and Scopus to identify peer-reviewed articles that report on the use of evaluation and assessment for e-learning training. The search strings combined the concepts of e-learning, public health, and health science education, along with evaluation and frameworks. After the initial search, a screening process will be carried out to determine the relevance of the identified studies to the research question. Data related to the characteristics of the included studies, the characteristics of the e-learning technology used in the studies, and the study outcomes will be extracted from the eligible articles. The extracted data will then undergo a structured, descriptive, quantitative, and qualitative content analysis to synthesize the information from the selected studies. RESULTS:  Initial database searches yielded a total of 980 results. Duplicates have been removed, and title and abstract screening of the 805 remaining extracted articles are underway. Quantitative and qualitative findings from the reviewed articles will be presented to answer the study objective. CONCLUSIONS: This scoping review will provide global and public health educators with a comprehensive overview of the current state of e-learning evaluation. By identifying existing e-learning frameworks and tools, the findings will offer valuable guidance for further advancements in global and public health e-learning evaluation. The study will also enable the creation of a comprehensive, evidence-based e-learning evaluation framework and tools, which will improve the quality and accountability of global health and public health education. Ultimately, this will contribute to better health outcomes. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/49955.

Circulating Extracellular Vesicles in Subarachnoid Hemorrhage Patients: Characterization and Cellular Effects.

Circulating extracellular vesicles (EVs) may play a pathophysiological role in the onset of complications of subarachnoid hemorrhage (SAH), potentially contributing to the development of vasospasm (VP). In this study, we aimed to characterize circulating EVs in SAH patients and examine their effects on endothelial and smooth muscle cells (SMCs). In a total of 18 SAH patients, 10 with VP (VP), 8 without VP (NVP), and 5 healthy controls (HC), clinical variables were recorded at different time points. EVs isolated from plasma samples were characterized and used to stimulate human vascular endothelial cells (HUVECs) and SMCs. We found that EVs from SAH patients expressed markers of T-lymphocytes and platelets and had a larger size and a higher concentration compared to those from HC. Moreover, EVs from VP patients reduced cell viability and mitochondrial membrane potential in HUVECs and increased oxidants and nitric oxide (NO) release. Furthermore, EVs from SAH patients increased intracellular calcium levels in SMCs. Altogether, our findings reveal an altered pattern of circulating EVs in SAH patients, suggesting their pathogenic role in promoting endothelial damage and enhancing smooth muscle reactivity. These results have significant implications for the use of EVs as potential diagnostic/prognostic markers and therapeutic tools in SAH management.

Unraveling the key drivers of community composition in the agri-food trade network.

In the complex global food system, the dynamics associated with international food trade have become crucial determinants of food security. In this paper, we employ a community detection approach along with a supervised learning technique to explore the evolution of communities in the agri-food trade network and to identify key factors influencing their composition. By leveraging a large dataset that includes both volume and monetary value of trades, we identify similarities between countries and uncover the primary drivers that shape trade dynamics over time. The analysis also takes into account the impact of evolving climate conditions on food production and trading. The results highlight how the network's topological structure is continuously evolving, influencing the composition of communities over time. Alongside geographical proximity and geo-political relations, our analysis identifies sustainability, climate and food nutrition aspects as emerging factors that contribute to explaining trade relationships. These findings shed light on the intricate interactions within the global food trade system and provide valuable insights into the factors affecting its stability.

Vulnerability of migrant women during disasters: a scoping review of the literature.

BACKGROUND: Disasters have an unequal impact on the population because of differences in conditions of vulnerability, exposure, and capacity. Migrants and women are among the groups that are at greater risk for and disproportionately affected by disasters. However, despite the large body of evidence that analyzes their vulnerability separately, disaster research that targets migrant women is scant. The aim of this scoping review was to analyze the published scientific literature concerning the vulnerability of migrant women and the consequent negative impact they experience during disasters. METHODS: A literature search was conducted on December 15th, 2021 on Pubmed, Scopus, and Web of Science databases. No time filter was applied to the search. Information regarding the article's main characteristics and design, migrant women and their migration experience, as well as about the type of disaster was collected. The factors responsible for the vulnerability of migrant women and the negative outcomes experienced during a disaster were extracted and inductively clustered in main themes reflecting several vulnerability pathways. The review followed the Joanna Briggs Institute methodology for scoping reviews and relied on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). RESULTS: After full text review, 14 articles met the inclusion criteria. All of them adopted a qualitative methodology and focused on COVID-19. The pandemic negatively affected migrant women, by triggering numerous drivers that increased their level of exposure and vulnerability. Overall, six vulnerability factors have been identified: legal status, poverty conditions, pre-existing health conditions, limited agency, gender inequality and language and cultural barriers. These resulted in nine impacts: worsening of mental health status, poor access to care, worsening of physical health conditions, fraud, exacerbation of poverty, gender-based violence, jeopardization of educational path, and unfulfillment of their religious needs. CONCLUSIONS: This review provided an analysis of the vulnerability factors of migrant women and the pathways leading to negative outcomes during a disaster. Overall, the COVID-19 pandemic demonstrated that health equity is a goal that is still far to reach. The post-pandemic era should constitute the momentum for thoroughly addressing the social determinants of health that systematically marginalize the most vulnerable groups.

Promoting and supporting breastfeeding in a protracted emergency setting-Caregivers' and health workers' perceptions from North-East Nigeria.

Background: Breastfeeding (BF) should be protected, promoted, and supported for all infants in humanitarian settings. The re-establishment of exclusive BF is also a central part of the management of acutely malnourished infants under 6 months (<6 m). Médecins Sans Frontières (MSF) runs a nutrition project in Maiduguri, a protracted emergency setting in North-East Nigeria. This study aimed to explore caregivers' (CGs) and health workers' (HWs) perceptions of BF practice, promotion, and support among CGs with infants <6 m in this setting. Methods: We conducted a qualitative study using in-depth interviews and focus group discussions combined with non-participant observations. Participants included CGs of young infants enrolled in MSF nutritional programs or who attended health promotion activities in a displacement camp. MSF HWs were involved at different levels in BF promotion and support. Data were collected involving a local translator and analyzed using reflexive thematic analysis directly from audio recordings. Results: Participants described how feeding practices are shaped by family, community, and traditional beliefs. The perception of breastmilk insufficiency was common and led to early supplementary feeding with inexpensive but unsuitable products. Participants often linked insufficient breastmilk production with poor maternal nutrition and stress, in a context shaped by conflict and food insecurity. BF promotion was generally well received but could be improved if tailored to address specific barriers to exclusive BF. Interviewed CGs positively valued BF support received as part of the comprehensive treatment for infant malnutrition. One of the main challenges identified was the length of stay at the facility. Some participants perceived that improvements in BF were at risk of being lost after discharge if CGs lacked an enabling environment for BF. Conclusion: This study corroborates the strong influence of household and contextual factors on the practice, promotion, and support of BF. Despite identified challenges, the provision of BF support contributes to improvements in BF practice and was positively perceived by CGs in the studied setting. Greater attention should be directed toward providing support and follow-up for infants <6 m and their CGs in the community.

Experimental characterization of the thermo-optic coefficient vs. temperature for 4H-SiC and GaN semiconductors at the wavelength of 632 nm.

The design of semiconductor-based photonic devices requires precise knowledge of the refractive index of the optical materials, a not constant parameter over the operating temperature range. However, the variation of the refractive index with the temperature, the thermo-optic coefficient, is itself temperature-dependent. A precise characterization of the thermo-optic coefficient in a wide temperature range is therefore essential for the design of nonlinear optical devices, active and passive integrated photonic devices and, more in general, for the semiconductor technology explored at different wavelengths, from the visible domain to the infrared or ultraviolet spectrum. In this paper, after an accurate ellipsometric and micro-Raman spectroscopy characterization, the temperature dependence of the thermo-optic coefficient ([Formula: see text]) for 4H-SiC and GaN in a wide range of temperature between room temperature to T = 500 K in the visible range spectrum, at a wavelength of λ = 632.8 nm, is experimentally evaluated. For this purpose, using the samples as a Fabry-Perot cavity, an interferometric technique is employed. The experimental results, for both semiconductors, show a linear dependence with a high determination coefficient, R2 of 0.9648 and 0.958, for 4H-SiC and GaN, respectively, in the considered temperature range.

The Challenge of Mass Casualty Incident Response Simulation Exercise Design and Creation: A Modified Delphi Study.

BACKGROUND: A Mass Casualty Incident response (MCI) full scale exercise (FSEx) assures MCI first responder (FR) competencies. Simulation and serious gaming platforms (Simulation) have been considered to achieve and maintain FR competencies. The translational science (TS) T0 question was asked: how can FRs achieve similar MCI competencies as a FSEx through the use of MCI simulation exercises? METHODS: T1 stage (Scoping Review): PRISMA-ScR was conducted to develop statements for the T2 stage modified Delphi (mD) study. 1320 reference titles and abstracts were reviewed with 215 full articles progressing for full review leading to 97 undergoing data extraction.T2 stage (mD study): Selected experts were presented with 27 statements derived from T1 data with instruction to rank each statement on a 7-point linear numeric scale, where 1 = disagree and 7 = agree. Consensus amongst experts was defined as a standard deviation ≤ 1.0. RESULTS: After 3 mD rounds, 19 statements attained consensus and 8 did not attain consensus. CONCLUSIONS: MCI simulation exercises can be developed to achieve similar competencies as FSEx by incorporating the 19 statements that attained consensus through the TS stages of a scoping review (T1) and mD study (T2), and continuing to T3 implementation, and then T4 evaluation stages.

Teaching extent and military service improve undergraduate self-assessed knowledge in disaster medicine: An online survey study among Swedish medical and nursing students.

Background: The purpose of this study was to identify the possible needs for undergraduate disaster medicine education in Sweden and to make informed recommendations for the implementation of disaster medicine content in medical and nursing schools in Sweden. Methods: An online survey was distributed to undergraduate medical and nursing students through the directors of all medical and nursing programs at Swedish universities. The survey contained demographic questions, as well as questions about the amount of disaster medical education and previous experience with rescue, police, or military services. The final survey page contained self-assessments of disaster medical knowledge. Comparative statistics were applied between nursing and medical students, those with previous military service, and those without, as well as between universities. Results: A total of 500 medical and 408 nursing students participated in this study. A median of 2 h of disaster medicine education was provided to senior medical students and 4 h was provided to senior nursing students. Senior medical students scored their disaster medical knowledge lower than nursing students (t-test, p < 0.001). A proportion of 1% had served in rescue services or police, and 7% of the participants had a history of military service, of which 67% served in a medical role. Those who had served in rescue services, police, or the armed forces had a higher self-assessed disaster medical knowledge base than those who had not (p < 0.007 and p < 0.001, respectively). Conclusion: Most medical and nursing students in this study rated their disaster medical knowledge as insufficient. The correlation between the amount of disaster medical education and self-assessed disaster medical knowledge should influence and help direct Swedish educational policies.

Effect of Lactoferrin on Clinical Outcomes of Hospitalized Patients with COVID-19: The LAC Randomized Clinical Trial.

As lactoferrin is a nutritional supplement with proven antiviral and immunomodulatory abilities, it may be used to improve the clinical course of COVID-19. The clinical efficacy and safety of bovine lactoferrin were evaluated in the LAC randomized double-blind placebo-controlled trial. A total of 218 hospitalized adult patients with moderate-to-severe COVID-19 were randomized to receive 800 mg/die oral bovine lactoferrin (n = 113) or placebo (n = 105), both given in combination with standard COVID-19 therapy. No differences in lactoferrin vs. placebo were observed in the primary outcomes: the proportion of death or intensive care unit admission (risk ratio of 1.06 (95% CI 0.63-1.79)) or proportion of discharge or National Early Warning Score 2 (NEWS2) ≤ 2 within 14 days from enrollment (RR of 0.85 (95% CI 0.70-1.04)). Lactoferrin showed an excellent safety and tolerability profile. Even though bovine lactoferrin is safe and tolerable, our results do not support its use in hospitalized patients with moderate-to-severe COVID-19.

Relationship between intensive care surge capacity and hospital factors: an extensive experience.

As a prolonged surge scenario, the COVID-19 pandemic has offered an unparalleled opportunity to improve hospital surge capacity (SC) understanding and the ability to manage it. In this study, the authors report the experience of a large hospital network and evaluate potential relationships between Intensive Care Units SC (ICU-SC) and some hospital-related variables: bed occupancy, emergency department admissions, ward admission from ED, and elective surgery procedures. Pearson's partial correlation coefficient (r) has been used to define the relationship between SC and the daily values of the above variables, collected through a dedicated digital platform that also ensured a regular quality check of the data. The observation has concerned several levels of analysis, namely two different types of SC calculation (SC base-SCb and SC actual-SCa), hospital category level and multi-hospital level, and two consecutive pandemic waves. Among the 16 hospitals observed, the correlation was shown to be moderate-positive with non-ICU bed occupancy (r/ = 0.62, r/ = 0.54), strong/moderate with ICU bed occupancy (r/ = 0.72, r/ = 0.54), and moderate with ward admissions from ED (r/ = 0.50, r/ = 0.51) On the contrary, the correlation proved to be moderate-negative with ED admissions (r/ = - 0.69, r/ = - 0.62) and low with the number of elective surgery procedures (r/ = - 0.10, r/ = - 0.16). This study identified a positive correlation between SC and three variables monitored: ICU bed occupancy, non-ICU bed occupancy, and ward admissions from ED. On the contrary, the correlation was negative for ED admission and the number of elective surgery procedures. The results have been confirmed across all levels of analysis adopted.

In-Hospital Predictors of Need for Ventilatory Support and Mortality in Chest Trauma: A Multicenter Retrospective Study.

Chest trauma management often requires the use of invasive and non-invasive ventilation. To date, only a few studies investigated the predictors of the need for ventilatory support. Data on 1080 patients with chest trauma managed in two different centers were retrospectively analyzed. Univariate and multivariate analyses were performed to identify the predictors of tracheal intubation (TI), non-invasive mechanical ventilation (NIMV), and mortality. Rib fractures (p = 0.0001) fracture of the scapula, clavicle, or sternum (p = 0.045), hemothorax (p = 0.0035) pulmonary contusion (p = 0.0241), and a high Injury Severity Score (ISS) (p ≤ 0001) emerged as independent predictors of the need of TI. Rib fractures (p = 0.0009) hemothorax (p = 0.0027), pulmonary contusion (p = 0.0160) and a high ISS (p = 0.0001) were independent predictors of NIMV. The center of trauma care (p = 0.0279), age (p < 0.0001) peripheral oxygen saturation in the emergency department (p = 0.0010), ISS (p < 0.0001), and Revised Trauma Score (RTS) (p < 0.0001) were independent predictors of outcome. In conclusion, patients who do not require TI, while mandating ventilatory support with selected types of injuries and severity scores, are more likely to be subjected to NIMV. Trauma team expertise and the level of the trauma center could influence patient outcomes.

Interventions to support the re-establishment of breastfeeding and their application in humanitarian settings: A systematic review.

In 1998, the World Health Organisation (WHO) published general guidelines proposing essential measures to achieve relactation. Yet, increased knowledge about the practical set-up of relactation support interventions in different contexts is needed, especially in humanitarian settings, where nonbreastfed infants are particularly at risk. This study aimed to compile and assess the characteristics, outcomes and factors influencing the implementation of relactation support interventions reported since the latest WHO recommendations. We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, undertaking a search from Medline, Embase, PubMed Central, Web of Science, Global Health and CINAHL electronic databases. Studies published in English and Spanish, reporting characteristics and outcomes of relactation support provided to non-(breastfeeding) BF mothers with infants aged less than 6 months were included. Data were analysed by narrative synthesis and the Johanna Briggs Institute Critical Appraisal Tools were used for quality assessment. Overall, 16 studies met the inclusion criteria. Most were observational and conducted in middle-income countries, only one focused on humanitarian settings. Studies reported inpatient and community-based interventions, which generally followed WHO recommendations for relactation. In 13 out of 16 studies, over 80% of mothers restarted BF after receiving relactation support. Enabling factors included younger infant age, shorter lactation gap, mother's strong motivation, family support, and continuous skilled support. Although current literature suggests that intensive relactation support can contribute to re-establish BF, its application and effectiveness in humanitarian settings remain uncertain. Further research is needed to explore the effectiveness, feasibility and acceptability of different approaches to relactation support, especially in humanitarian settings.
