    Abstract Hypoxia-inducible factors (HIFs) are a family of nuclear transcription factors that serve as the master regulator of the adaptive response to hypoxia. In the lung, HIFs orchestrate multiple inflammatory pathways and signaling. They have been reported to have a major role in the initiation and progression of acute lung injury, chronic obstructive pulmonary disease, pulmonary fibrosis, and pulmonary hypertension. Although there seems to be a clear mechanistic role for both HIF 1α and 2α in pulmonary vascular diseases including PH, a successful translation into a definitive therapeutic modality has not been accomplished to date.

    Abstract If not properly managed, acute lung injuries, either through direct or indirect causes, have the potential to present serious risk for many patients worldwide. One of the mechanisms for the transition from acute lung injury (ALI) to the more serious acute respiratory distress syndrome (ARDS) is the deactivation of the native lung surfactant by injury-induced infiltrates to the alveolar space. Currently, there are no surfactant replacement therapies that are used to treat ALI and subsequent ARDS. In this paper, we present an indepth efficacy study of using a novel polymer lung surfactant (PLS, composed of poly(styrene-

    Abstract Introduction: Low- and middle-income countries (LMICs) account for 90% of deaths due to injury, largely due to hemorrhage. The increased hemorrhage mortality burden in LMICs is exacerbated by absent or ineffective prehospital care. Hemorrhage management (HM) is an essential component of prehospital care in LMICs, yet current practices for prehospital HM and outcomes from first responder HM training have yet to be summarized.
    Methods: This review describes the current literature on prehospital HM and the impact of first responder HM training in LMICs. Articles published between January 2000 and January 2023 were identified using PMC, MEDLINE, and Scopus databases following PRISMA-ScR guidelines. Inclusion criteria spanned first responder training programs delivering prehospital care for HM. Relevant articles were assessed for quality using the Newcastle-Ottawa scale.
    Results: Of the initial 994 articles, 20 met inclusion criteria representing 16 countries. Studies included randomized control trials, cohort studies, case control studies, reviews, and epidemiological studies. Basic HM curricula were found in 15 studies and advanced HM curricula were found in six studies. Traumatic hemorrhage was indicated in 17 studies while obstetric hemorrhage was indicated in three studies. First responders indicated HM use in 55%-76% of encounters, the most frequent skill they reported using. Mean improvements in HM knowledge acquisition post-course ranged from 23 to 58 percentage points following training for pressure and elevation, gauze application, and tourniquet application.
    Conclusions: Our study summarizes the current literature on prehospital HM in LMICs pertaining to epidemiology, interventions, and outcomes. HM resources should be a priority for further development.

    Abstract Curcumin is a safe, non-toxic, readily available and naturally occurring compound, an active constituent of Curcuma longa (turmeric). Curcumin could potentially treat diseases, but faces poor physicochemical and pharmacological characteristics. To overcome these limitations, we developed a stable, water-soluble formulation of curcumin called cyclodextrin-complexed curcumin (CDC). We have previously shown that direct delivery of CDC to the lung following lipopolysaccharides exposure reduces acute lung injury (ALI) and effectively reduces lung injury, inflammation and mortality in mice following Klebsiella pneumoniae. Recently, we found that administration of CDC led to a significant reduction in angiotensin-converting enzyme 2 and signal transducer and activator of transcription 3 expression in gene and protein levels following pneumonia, indicating its potential in treating coronavirus disease 2019 (COVID-19). In this review, we consider the clinical features of ALI and acute respiratory distress syndrome (ARDS) and the role of curcumin in modulating the pathogenesis of bacterial/viral-induced ARDS and COVID-19.

    Abstract The development of sustainable surgical systems in low- and middle-income countries is imperative given the rising burden of surgical disease processes. Surgical conditions now account for more than 11% of the overall burden of disease. Although the administration of surgical care has historically taken a variety of forms, a sustainable surgical model requires the utilization of robust clinical infrastructure, curricula for educating future staff and trainees, and research to promote quality improvement. Increasing the number of trained anesthesia providers, surgeons, and nurses is of utmost importance; task shifting may be necessary to most efficiently offset the shortage of health care providers.

    Abstract Introduction: In 2019, the World Health Assembly declared emergency care essential to achieve the 2030 Sustainable Development Goals. Few sub-Saharan African (SSA) countries have developed robust approaches to sustainably deliver emergency medical services (EMS) at scale, as high-income country models are financially impractical. Innovative reassessment of EMS delivery in resource-limited settings is necessary as timely emergency care access can substantially reduce mortality.
    Materials and methods: We developed the Lay First Responder (LFR) program by training 1,291 pre-existing motorcycle taxi drivers, a predominant form of short-distance transport in sub-Saharan Africa, to provide trauma care and transport for road traffic injuries. Three pilot programs were launched in staggered fashion between 2016 and 2019 in West, Central, and East Africa and a 5.5 h curriculum was iteratively developed to train first responders. Longitudinal data on patient impact (patient demographics, injury characteristics, and treatment rendered), emergency care knowledge acquisition/retention, and social/financial effects of LFR training were collected and pooled across three sites for collective analysis. Novel cost-effectiveness ratios were calculated based on prospective cost data from each site. Previously projected aggregate disability-adjusted life years (DALYs) addressable by LFRs were used to inform cost-effectiveness ratios($USD cost per DALY averted). Cost-effectiveness ratios were then compared against African per capita gross domestic product (GDP), following WHOCHOICE guidelines, which state ratios less than GDP per capita are "very cost-effective."
    Results: In 2,171 total patient encounters across all three pilot sites, LFRs most frequently provided hemorrhage control in 61 % of patient encounters and patient transport by motorcycle in 98.5 %. Median pre-/post-test scores improved by 34.1 percentage points (39.5% vs.73.6 %, p < 0.0001) with significant knowledge retention at six months. 75 % of initial participants remain voluntarily involved 3 years post-course, reporting increased local stature and customer acquisition(income 32.0 % greater than non-trained counterparts). Locally sourced first-aid materials cost $6.54USD/participant. Cost-effectiveness analysis demonstrated cost per DALY averted=$51.65USD.
    Conclusion: LFR training is highly cost-effective according to WHOCHOICE guidelines and expands emergency care access. The LFR program may be an alternative approach to formal ambulance-reliant EMS that are cost-prohibitive in resource-limited, sub-Saharan African settings. A novel social/financial mechanism appears to incentivize long-term voluntary LFR involvement, which may sustain programs in resource-limited settings.

    Abstract Background: The field of medicine and synthetic drug development have advanced rapidly over the past few decades. However, research on alternative medicine such as phytochemicals cannot be ignored. The main reason for prominent curiosity about phytochemicals stems from the belief that usage of natural compounds is safer and has lesser detrimental side effects.
    Objective: The aim of the present review was to discuss in detail with several phytochemicals that have been studied or are being studied in the context of various neurological disorders including depression, Alzheimer's disease, Huntington's disease and even neuroinflammatory disorders such as encephalitis.
    Methods: The potential role of phytochemicals in the treatment or management of symptoms associated with neurological disorders have been included in this article. All data included in this paper has been pooled from various databases including Google Scholar, PubMed, Science Direct, Springer and Wiley Online Library.
    Results: Phytochemicals have been widely studied for their therapeutic properties associated with neurological disorders. Using various experimental techniques for both in vivo and in vitro experiments, studies have shown that phytochemicals do have antioxidant, anti-inflammatory and neuroprotective activities which play major roles in the treatment of neurological diseases.
    Conclusion: Even though there has been compelling evidence of the therapeutic role of phytochemicals, further research is still required to evaluate the safety and efficacy of these medicines. Using previously published papers as foundation for additional research such as preclinical studies and clinical trials, phytochemicals can become a safer alternative to synthetic drugs for treating a spectrum of neurological diseases.
