Review
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in December 2019 with staggering economic fallout and human suffering. The unique structure of SARS-CoV-2 and its underlying pathogenic mechanism were responsible for the global pandemic. In addition to the direct damage caused by the virus, SARS-CoV-2 triggers an abnormal immune response leading to a cytokine storm, culminating in acute respiratory distress syndrome and other fatal diseases that pose a significant challenge to clinicians. Therefore, potential treatments should focus not only on eliminating the virus but also on alleviating or controlling acute immune/inflammatory responses. Current management strategies for COVID-19 include preventative measures and supportive care, while the role of the host immune/inflammatory response in disease progression has largely been overlooked. Understanding the interaction between SARS-CoV-2 and its receptors, as well as the underlying pathogenesis, has proven to be helpful for disease prevention, early recognition of disease progression, vaccine development, and interventions aimed at reducing immunopathology have been shown to reduce adverse clinical outcomes and improve prognosis. Moreover, several key mutations in the SARS-CoV-2 genome sequence result in an enhanced binding affinity to the host cell receptor, or produce immune escape, leading to either increased virus transmissibility or virulence of variants that carry these mutations. This review characterizes the structural features of SARS-CoV-2, its variants, and their interaction with the immune system, emphasizing the role of dysfunctional immune responses and cytokine storm in disease progression. Additionally, potential therapeutic options are reviewed, providing critical insights into disease management, exploring effective approaches to deal with the public health crises caused by SARS-CoV-2.

The literature suggests that there is a significant overlap in definition, measurement, and outcomes between trauma and bullying victimization, but the relative impact on current emotional distress of these events has not been explored. The goal of the current study was to explore whether traditional and cyber bullying victimization has a similar negative impact on current emotional disrtresss as other adverse childhood experiences which may also lead to a traumatic response. In addition, this study examined whether the association between bullying victimization and emotional distress is exacerbated when individuals also experience additional ACEs. Retrospective reports from a diverse sample of 576 adults were collected via an online survey. When ranked against other ACEs such as viewing family mental health problems or substance abuse, or verbal, physical, emotional, and sexual victimization not from peers, nearly 30% of participants ranked bullying victimization as having the most negative impact on their levels of emotional distress. Multi-group path analyses indicated that experiencing additional ACEs seems to exacerbate distress caused by bullying and cyber bullying victimization. The current study suggests that bullying victimization may be just as detrimental as other types of ACEs that occur in childhood.

Children adopted from out-of-home care may present symptoms of developmental trauma that affect their functioning. This puts their adoptive parents at risk of experiencing secondary trauma. The purpose of this research was to understand the experience of adoptive parents who self-report symptoms of secondary trauma in relation to their child's symptoms of developmental trauma. Individual semi-structured interviews were conducted, transcribed, and analyzed using Braun and Clarke's ((2), 77-101, 2006) thematic analysis method. Ten adoptive parents were recruited from four community organizations providing support for adoptive parents or parents of children with attachment disorder. All participants reported feeling strong emotions related to secondary trauma, as well as physical and mental health issues that appeared after the child's arrival in the family. Participants reported experiencing aggression from their child, which greatly disturbed the parent-child relationship and led to the child being placed in residential care for half of the families involved in the study. Secondary trauma was insufficient to fully capture the experience of these parents as it failed to account for the suffering and distress linked to their efforts to establish a parent-child relationship. Instead, was used to describe this experience. The authors conclude that a better understanding of filial trauma can contribute to improving post-adoption services for parents struggling to fulfill one of the most important roles of their lives: being the parent of their child.

Young people that offend evidence higher rates of trauma and post-traumatic distress than non-offending peers. Effects of post-traumatic distress also parallel research on some young people that participate in restorative justice (RJ) meetings who struggle with communication, emotionally withdraw, become agitated or defiant, evidence poor understanding of harms they have caused, or fail to demonstrate empathy or remorse. In this paper I suggest post-traumatic distress may explain some variation in RJ process and outcomes hitherto ignored in existing research. I also suggest research on trauma in young people raises four areas of concern for thinking about RJ as a "trauma-informed" practice, including impacts of trauma and post-traumatic distress on (1) oral language proficiency and non-verbal communication; (2) the experience and expression of emotions; (3) offender perceptions of fairness and respect; and (4) difficulties in behavioural changes following participation in RJ meetings. I conclude with discussion of challenges to and suggestions for using RJ as a trauma-informed practice in youth justice settings.

PURPOSE
Different types of adverse childhood experiences (ACEs) may be differentially linked to mental and behavioral health. Additionally, spirituality is associated with well-being, but little research has examined whether it is protective in the context of ACEs. The present study examines the influence of maltreatment and household dysfunction ACEs on distress, substance use, and sexual risk taking, and tests whether spirituality moderates the associations between childhood maltreatment, household dysfunction and distress, substance use, and sexual risk taking.
METHOD
314 college students completed the ACE-Q and measures of general mental (distress) and behavioral (substance use, sexual risk taking) health. To examine the distinct effects of maltreatment and household dysfunction on mental and behavior health, linear regression models that included both ACE types as predictors were constructed for each of the health variables. Moderation between spirituality and each type of ACEs was then examined for each outcome.
RESULTS
Childhood maltreatment predicted greater distress and sexual risk-taking even after accounting for household dysfunction, and household dysfunction predicted greater substance use even after accounting for childhood maltreatment. Childhood maltreatment interacted significantly with spirituality to predict distress, but in the opposite direction than was hypothesized. That is, the relationship between cumulative childhood maltreatment ACEs and distress was stronger among those with higher levels of spirituality.
CONCLUSIONS
Results suggest that childhood maltreatment and household dysfunction ACEs are linked to distinct mental and behavioral health consequences among young adults. Additionally, while spirituality is associated generally with better mental and behavioral health, our findings suggest that it does not buffer the impacts of childhood maltreatment or household dysfunction.

BACKGROUND
Diabetes mellitus (DM) is a major public health concern in India, and entails a severe burden in terms of disability, death, and economic cost. This study examined the out-of-pocket health expenditure (OOPE) and financial burden associated with DM care in India.
METHODS
The study used data from the latest round of the National Sample Survey on health, which covered 555,115 individuals from 113,823 households in India. In the present study, data of 1216 individuals who sought inpatient treatment and 6527 individuals who sought outpatient care for DM were analysed.
RESULTS
In India, 10.04 per 1000 persons reported having DM during the last 15 days before the survey date, varying from 6.94/1000 in rural areas to 17.45/1000 in urban areas. Nearly 38% of Indian households with diabetic members experienced catastrophic health expenditure (at the 10% threshold) and approximately 10% of DM-affected households were pushed below the poverty line because of OOPE, irrespective of the type of care sought. 48.5% of households used distressed sources to finance the inpatient costs of DM. Medicines constituted one of the largest proportion of total health expenditure, regardless of the type of care sought or type of healthcare facility visited. The average monthly OOPE was over 4.5-fold and 2.5-fold higher for households who sought inpatient and outpatient care, respectively, from private health facilities, compared with those treated at public facilities. Notably, the financial burden was more severe for households residing in rural areas, those in lower economic quintiles, those belonging to marginalised social groups, and those using private health facilities.
CONCLUSION
The burden of DM and its associated financial ramifications necessitate policy measures, such as prioritising health promotion and disease prevention strategies, strengthening public healthcare facilities, improved regulation of private healthcare providers, and bringing outpatient services under the purview of health insurance, to manage the diabetes epidemic and mitigate its financial impact.

The mitochondrion is a multifunctional organelle that modulates multiple systems critical for homeostasis during pathophysiological stress. Variation in mitochondrial DNA (mtDNA) copy number (mtDNAcn), a key mitochondrial change associated with chronic stress, is an emerging biomarker for disease pathology and progression. mtDNAcn can be quantified from whole blood samples using qPCR to determine the ratio of mtDNA to nuclear DNA. However, the collection of blood samples in pediatric populations, particularly in infants and young children, can be technically challenging, yield much smaller volume samples, and can be distressing for the patients and their caregivers. Therefore, we have validated a mtDNAcn assay utilizing DNA from simple buccal swabs (Isohelix SK-2S) and report here it's performance in specimens from infants (age = <12 months). Utilizing qPCR to amplify ∼200 bp regions from two mitochondrial () and two nuclear () genes, we demonstrated absolute (100%) concordance with results from low-pass whole genome sequencing (lpWGS). We believe that this method overcomes key obstacles to measuring mtDNAcn in pediatric populations and creates the possibility for development of clinical assays to measure mitochondrial change during pathophysiological stress.

Randomized Controlled Trial
BACKGROUND
We aimed to assess the efficacy of the neutrophil elastase inhibitor, sivelestat, in the treatment of sepsis-induced acute respiratory distress syndrome (ARDS) and septic cardiomyopathy (SCM).
METHODS
Between January 2019 and December 2021, we conducted a randomized trial on patients who had been diagnosed with sepsis-induced acute respiratory distress syndrome (ARDS) and septic cardiomyopathy (SCM) at Wuhan Union Hospital. The patients were divided into two groups by random envelop method, the Sivelestat group and the Control group. We measured the serum concentrations of Interleukin (IL)-6, IL-8, Tumor necrosis factor-α (TNF-α), and High-mobility group box 1 (HMGB1) at five time points, which were the baseline, 12 h, 24 h, 48 h, and 72 h after admission to the ICU. We evaluated the cardiac function by sonography and the heart rate variability (HRV) with 24-hour Holter recording between the time of admission to the intensive care unit (ICU) and 72 h after Sivelestat treatment.
RESULTS
From January 2019 to December 2021, a total of 70 patients were included in this study. The levels of IL-6, IL-8, and TNF-α were significantly lower in the Sivelestat group at different time points (12 h, 24 h, 48 h, and 72 h). HMGB1 levels were significantly lower at 72 h after Sivelestat treatment (19.46 ± 2.63pg/mL vs. 21.20 ± 2.03pg/mL, P = 0.003). The stroke volume (SV), tricuspid annular plane systolic excursion (TAPSE), early to late diastolic transmitral flow velocity (E/A), early (e') and late (a') diastoles were significantly low in the Control group compared with the Sivelestat group. Tei index was high in the Control group compared with the Sivelestat group (0.60 ± 0.08 vs. 0.56 ± 0.07, P = 0.029). The result of HRV showed significant differences in standard deviation of normal-to-normal intervals (SDNN), low frequency (LF), and LF/HF (high frequency) between the two groups.
CONCLUSIONS
Sivelestat can significantly reduce the levels of serum inflammatory factors, improve cardiac function, and reduce heart rate variability in patients with Sepsis-induced ARDS and SCM.

Hypoxemia and its clinical predictors among children with respiratory distress admitted to the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia.
INTRODUCTION
Hypoxemia is a common complication of childhood respiratory tract infections and non-respiratory infections. Hypoxemic children have a five-fold increased risk of death compared to children without hypoxemia. In addition, there is limited evidence about hypoxemia and clinical predictors in Ethiopia. Therefore, this study was conducted to assess the prevalence and clinical predictors of hypoxemia among children with respiratory distress admitted to the University of Gondar Comprehensive Specialized Hospital.
METHODS
An institutional-based cross-sectional study was conducted from December 2020 to May 2021 in northwest Ethiopia. A total of 399 study participants were selected using systematic random sampling. The oxygen saturation of the child was measured using Masimo rad-5 pulse oximetry. SPSS version 21 software was used for statistical analysis.
RESULT
In this study, the prevalence of hypoxemia among children with respiratory distress was 63.5%. The clinical signs and symptoms significantly associated with hypoxemia were: head-nodding (AOR: 4.1, 95% CI: 1.81-9.28) and chest indrawing (AOR: 3.08, 95% CI: 1.32-7.16) which were considered statistically the risk factors for hypoxemia while inability to feed (AOR: 0.13, 95% CI: 0.02-0.77) was the protective factor for hypoxemia. The most sensitive predictors of hypoxemia were fast breathing with sensitivity (98.4%), nasal flaring (100.0%), chest indrawing (83.6%), and intercostal retraction (93.1%). The best specific predictors of hypoxemia were breathing difficulty with specificity (79.4%), inability to feed (100.0%), wheezing (83.0%), cyanosis (98.6%), impaired consciousness (94.2%), head-nodding (88.7%), and supra-sternal retraction (96.5%).
CONCLUSION AND RECOMMENDATION
The prevalence of hypoxemia among children was high. The predictors of hypoxemia were the inability to feed, head nodding, and chest indrawing. It is recommended that the health care settings provide immediate care for the children with an inability to feed, head nodding, and chest indrawing. The policymakers better to focus on preventive strategies, particularly those with the most specific clinical predictors.

This study determined whether compared to conventional mechanical ventilation (MV), extracorporeal membrane oxygenation (ECMO) is associated with decreased hospital mortality or fibrotic changes in patients with COVID-19 acute respiratory distress syndrome. A cohort of 72 patients treated with ECMO and 390 with conventional MV were analyzed (February 2020-December 2021). A target trial was emulated comparing the treatment strategies of initiating ECMO vs no ECMO within 7 days of MV in patients with a PaO/FiO < 80 or a PaCO ≥ 60 mmHg. A total of 222 patients met the eligibility criteria for the emulated trial, among whom 42 initiated ECMO. ECMO was associated with a lower risk of hospital mortality (hazard ratio [HR], 0.56; 95% confidence interval [CI] 0.36-0.96). The risk was lower in patients who were younger (age < 70 years), had less comorbidities (Charlson comorbidity index < 2), underwent prone positioning before ECMO, and had driving pressures ≥ 15 cmHO at inclusion. Furthermore, ECMO was associated with a lower risk of fibrotic changes (HR, 0.30; 95% CI 0.11-0.70). However, the finding was limited due to relatively small number of patients and differences in observability between the ECMO and conventional MV groups.
