Characteristics of injuries during the 2006 Lebanon conflict: a three-center retrospective study of survivors, 16 years after the conflict.

Background: Armed conflict injury is a growing public health concern, particularly in regions like the Middle East and North Africa (MENA). The protracted conflicts and political unrest in this region have led to a substantial number of injuries. Despite this, there is still limited understanding of the specific injury patterns stemming from conflicts, such as the 2006 Lebanon conflict. This study aimed to assess the characteristics and burdens of injuries resulting from this conflict, which occurred 16 years prior to this research. Methods: This retrospective study analyzed data of individuals affected by the 2006 Lebanon conflict, across three tertiary care centers. Demographics, injuries, complications, injury management, and hospitalization expenses were extracted from medical records and analyzed using SPSS version 29.0. Categorical variables were presented as counts and proportions, and continuous variables as mean ± standard deviation (SD). Hospital comparisons utilized chi-square or Fisher's exact tests for categorical variables, and one-way ANOVAs for continuous variables. Analysis was conducted from September to November 2023. Results: Across three hospitals, 341 patients were studied, comprising 73.6% males and 26.4% females. Among them, a notable proportion (57.3% males and 34.1% females) fell within the 18-39 age range. Children and adolescents under 18 years accounted for 15.9% of males and 25.9% of females. Blast-related injuries predominated, with 24.5% resulting from direct damage caused by explosive parts and 33.3% from blast wave forces. Extremity trauma occurred in 49.0% of patients, and head/neck trauma in 24.9%. Common injuries, including penetrating, musculoskeletal, and traumatic brain injuries affected 34.9%, 31.1, and 10.0% of patients, respectively. Wound repair, fracture treatment, and debridement were the most performed procedures on 15.5, 13.5 and 9.7% of the patients, respectively. The total cost of care was USD 692,711, largely covered by the Ministry of Public Health (95.9%). Conclusion: Conflict-related injuries significantly contribute to the global burden of disease. Therefore, there is a pressing need to improve national guidelines to prioritize life-threatening cases and potential long-term disabilities. Furthermore, enhancing electronic registry systems to collect clinical data on injured patients is essential for conducting research and better understanding the needs of conflict casualties.

The integration of ortho-plastic limb salvage teams in the humanitarian response to violence-related open tibial fractures: evaluating outcomes in the Gaza Strip.

BACKGROUND: Limb salvage by ortho-plastic teams is the standard protocol for treating open tibial fractures in high-income countries, but there's limited research on this in conflict settings like the Gaza Strip. This study assessed the clinical impact of gunshot-related open tibial fractures, compared patient management by orthopedic and ortho-plastic teams, and identified the risk factors for bone non-union in this context. METHODS: A retrospective review of medical records was conducted on Gaza Strip patients with gunshot-induced-open tibial fractures from March 2018 to October 2020. Data included patient demographics, treatments, and outcomes, with at least one year of follow-up. Primary outcomes were union, non-union, infection, and amputation. RESULTS: The study included 244 injured individuals, predominantly young adult males (99.2%) with nearly half (48.9%) having Gustilo-Anderson type IIIB fractures and more than half (66.8%) with over 1 cm of bone loss. Most patients required surgery, including rotational flaps and bone grafts with a median of 3 admissions and 9 surgeries. Ortho-plastic teams managed more severe muscle and skin injuries, cases with bone loss > 1 cm, and performed less debridement compared to other groups, though these differences were not statistically significant. Non-union occurred in 53% of the cases, with the ortho-plastic team having the highest rate at 63.6%. Infection rates were high (92.5%), but no significant differences in bone or infection outcomes were observed among the different groups. Logistic regression analysis identified bone loss > 1 cm, vascular injury, and the use of a definitive fixator at the first application as predictors of non-union. CONCLUSIONS: This study highlights the severity and complexity of such injuries, emphasizing their significant impact on patients and the healthcare system. Ortho-plastic teams appeared to play a crucial role in managing severe cases. However, further research is still needed to enhance our understanding of how to effectively manage these injuries.

Long-term burden of war injuries among civilians in LMICs: case of the July 2006 war in Lebanon.

Introduction: Lebanon, a country located on the eastern shore of the Mediterranean Sea, is one of the world's smaller sovereign states. In the past few decades, Lebanon endured a perpetual political turmoil and several armed conflicts. July 12, 2006, marked the start of a one-month war in Lebanon, which resulted in thousands of casualties. Little is known about the long-term consequences of war injuries inflicted on civilians during the July 2006 war. Methods: The objectives of this paper were to identify and evaluate: 1- civilians' access to healthcare and medicine under conditions of war; 2- the long-term socioeconomic burden on injured civilians; and 3- their quality of life more than a decade post-war. We adopted a mixed-method research design with an emphasis on the qualitative component. We conducted interviews with patients, collected clinical and financial data from hospital medical records, and administered a self-rated health questionnaire, the EQ-5D-5L. Simple descriptive statistics were calculated using Excel. NVivo 12® was used for data management and thematic analysis. Results: We conducted 25 interviews. Injured civilians were mostly males, average age of 27. The most common mechanism of injury was blast injury. Most patients underwent multiple surgeries as well as revision surgeries. The thematic analysis revealed three themes: 1- recall of the time of the incident, the thousand miles journey, and patients' access to services; 2- post-trauma sequelae and services; and 3- long-term impact. Patients described the long-term burden including chronic pain, poor mobility, anxiety or depression, and limited activities of daily living. Discussion: Civilians injured during the July 2006 war described the traumatising events they endured during the war and the limited access to medical care during and post-war. Up until this study was conducted, affected civilians were still experiencing physical, psychological, and financial sequelae. Acknowledging the limitations of this study, which include a small sample size and recall bias, the findings underscore the necessity for the expansion of services catering to civilians injured during wartime.

Responding to the Humanitarian Crisis in Gaza: Damned if You do Damned if You don't!

Palestine, since 1948, has endured frequent military occupations and uprisings, intifadas, in a limited geographic area that has resulted in one of the worst humanitarian crises. The prolonged nature of this military occupation has created a biosphere of war that is uninhabitable, whereby Palestinians suffer from physical, psychological, and social wounds. Israel also imposed restrictive measures in Gaza, making it difficult for Palestinians to obtain permits to work and travel throughout Palestine. Israel continued to intensify the restrictions on Gaza, reaching a blockade on the Gaza Strip, which cut off Palestinians from Jerusalem, where hospitals, banks, and vital services are found. This form of permanent siege resulted in a surge in the unemployment rate, poverty, and poor nutritional and wellbeing status. The siege also resulted in the largest open-air prison, as people became stuck between an incomplete life and the absence of total death. The major challenge is that humanitarian interventions, in the case of Gaza, are ineffective, as they are part of the siege framework. This is because any humanitarian aid meant for Gaza needs to be approved by Israel. Thus, when the emergency becomes chronic and humanitarian interventions become part of the siege framework, how can Gaza rebuild its health capacity in a permanent emergency, and to what extent can the humanitarian sector make a change?

Perceived facilitators and barriers to the provision of sexual and reproductive health services in response to the Syrian refugee crisis in Lebanon.

BACKGROUND: The Syrian crisis has resulted in one of the worst humanitarian disasters in modern history. Inadequate access to and use of sexual and reproductive health services is a prevailing issue among adolescent girls and young refugee women in humanitarian settings. OBJECTIVES: This article aimed to explore and describe the perceived extent of implementation of the different objectives and activities outlined within the minimum initial service package for reproductive health in crisis services in Lebanon, from the perspectives of a diverse set of stakeholders from leading organizations (public, private, primary health centers, nongovernmental organizations) that were directly engaged with the Syrian refugee crisis response. DESIGN: This study is a cross-sectional survey conducted using a standardized and validated questionnaire. METHODS: Centers that provided sexual and reproductive health services to Syrian refugees in Lebanon were mapped. The study was based on a purposive sampling approach, retrieving 52 eligible organizations to cover most areas in the country. A total of 43 centers accepted to take part in the study. The head of the center was then asked to identify one person in their center who holds adequate knowledge of the explained objectives of the survey. Accordingly, the identified person was asked to fill out the survey. RESULTS: A considerable portion of the respondents had limited knowledge about the specific minimum initial service package objectives and related sexual and reproductive health services. The study found the presence of a leading reproductive health agency, the Lebanese MoPH, as an essential facilitating factor for sexual and reproductive health service provision in Lebanon and has helped in overseeing the overall sexual and reproductive health coordination response for Syrian refugees (76.74% of all respondents). The identified challenges impeding adequate sexual and reproductive health services provision for Syrian refugees included (1) insufficient supplies (46.51%); (2) insufficient funds (39.53%); and (3) shortage of staff (39.53%). CONCLUSION: The recommendations for improved sexual and reproductive health service provision include the need for (1) enforcing the lead minimum initial service package agency for adequate and effective coordination, reporting, and accountability and (2) increasing funding for training staff and healthcare workers, as well as improving the overall quality of services available with the inclusion of family planning services, purchasing the necessary commodities, supplies and equipment, and covering fees associated with the different sexual and reproductive health services.

The state of cancer research in fragile and conflict-affected settings in the Middle East and North Africa Region: A bibliometric analysis.

Background: Cancer represents a disproportionate burden in LMICs, especially conflict-affected countries in the MENA region. Research output on cancer fails to match the growing burden in the region. This bibliometric study aims to examine the status and trends of cancer research in fragile and conflict-affected settings in the MENA region from 2000 to 2021, while also incorporating economic and demographic indicators as additional factors of analysis. Methods: The Web of Science databases were searched for publications related to cancer research in Iraq, Lebanon, Libya, Palestine, Syria, and Yemen from January 1, 2000, to December 31, 2021. The retrieved publications were screened based on preset eligibility criteria and the final list was analyzed using the Bibliometrix Package in R to generate the annual scientific production and citations, journals, institutions, authors, collaborations, keywords, and title co-occurrence. Each country's annual scientific production was analyzed against its annual GDP per capita. Results: A total of 4,280 documents met the inclusion criteria in this research. The annual number of publications revealed a significant increase over the past 20 years. These publications were mostly published in international journals that had impact factors rated in the 3rd or 4th quartiles. The overall contribution of researchers from Fragile and Conflict-Affected Settings (FCS) to cancer research was 6.5% of the MENA cancer research productivity, despite comprising around 23% of the total MENA region's population. Lebanon had the highest publication productivity at the country level, followed by Iraq and Syria. GDP per capita was not significantly correlated with cancer research across the countries under investigation. At the institutional level, the American University of Beirut was the most prolific institution and had the highest number of collaborations and the widest range of cooperative partners. Most first authors were male researchers. There is an interest in cancer expression, prevalence, diagnosis, and management in terms of commonly researched topics. Conclusion: This study underscores the need for a concerted effort to improve cancer research outcomes in FCS, which can be achieved through targeted research, increased investment in research infrastructure and capacity-building initiatives, and greater regional and global collaboration.

SGLT2 Inhibitor-Dapagliflozin Attenuates Diabetes-Induced Renal Injury by Regulating Inflammation through a CYP4A/20-HETE Signaling Mechanism.

Diabetic kidney disease (DKD) is a serious complication of diabetes, affecting millions of people worldwide. Inflammation and oxidative stress are key contributors to the development and progression of DKD, making them potential targets for therapeutic interventions. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have emerged as a promising class of drugs, with evidence demonstrating that they can improve renal outcomes in people with diabetes. However, the exact mechanism by which SGLT2i exert their renoprotective effects is not yet fully understood. This study demonstrates that dapagliflozin treatment attenuates renal injury observed in type 2 diabetic mice. This is evidenced by the reduction in renal hypertrophy and proteinuria. Furthermore, dapagliflozin decreases tubulointerstitial fibrosis and glomerulosclerosis by mitigating the generation of reactive oxygen species and inflammation, which are activated through the production of CYP4A-induced 20-HETE. Our findings provide insights onto a novel mechanistic pathway by which SGLT2i exerts their renoprotective effects. Overall, and to our knowledge, the study provides critical insights into the pathophysiology of DKD and represents an important step towards improving outcomes for people with this devastating condition.

Inhibition of the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) stimulates osteoblastogenesis by potentiating bone morphogenetic protein 2 (BMP2) responses.

The catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) is a pleiotropic enzyme involved in DNA repair, cell cycle control, and transcription regulation. A potential role for DNA-PKcs in the regulation of osteoblastogenesis remains to be established. We show that pharmacological inhibition of DNA-PKcs kinase activity or gene silencing of Prkdc (encoding DNA-PKcs) in murine osteoblastic MC3T3-E1 cells and human adipose-derived mesenchymal stromal cells markedly enhanced osteogenesis and the expression of osteoblast differentiation marker genes. Inhibition of DNA-PKcs inhibited cell cycle progression and increased osteogenesis by significantly enhancing the bone morphogenetic protein 2 response in osteoblasts and other mesenchymal cell types. Importantly, in vivo pharmacological inhibition of the kinase enhanced bone biomechanical properties. Bones from osteoblast-specific conditional Prkdc-knockout mice exhibited a similar phenotype of increased stiffness. In conclusion, DNA-PKcs negatively regulates osteoblast differentiation, and therefore DNA-PKcs inhibitors may have therapeutic potential for bone regeneration and metabolic bone diseases.

Role of the Nox4/AMPK/mTOR signaling axe in adipose inflammation-induced kidney injury.

Diabetic kidney disease is one of the most serious complications of diabetes worldwide and is the leading cause of end-stage renal disease. While research has primarily focused on hyperglycemia as a key player in the pathophysiology of diabetic complications, recently, increasing evidence have underlined the role of adipose inflammation in modulating the development and/or progression of diabetic kidney disease. This review focuses on how adipose inflammation contribute to diabetic kidney disease. Furthermore, it discusses in detail the underlying mechanisms of adipose inflammation, including pro-inflammatory cytokines, oxidative stress, and AMPK/mTOR signaling pathway and critically describes their role in diabetic kidney disease. This in-depth understanding of adipose inflammation and its impact on diabetic kidney disease highlights the need for novel interventions in the treatment of diabetic complications.

Hereditary vitamin D-resistant rickets in Lebanese patients: the p.R391S and p.H397P variants have different phenotypes.

BACKGROUND: Hereditary vitamin D-resistant rickets (HVDRR) is an autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) gene. Variable phenotypes have been associated with these mutations, and some of these were linked to the effects they have on the interacting partners of VDR, mainly the retinoic X receptor (RXR). METHODS: We examined four patients with HVDRR from three unrelated Lebanese families. All parents were consanguineous with normal phenotype. We used Sanger sequencing to identify mutations in the coding exons of VDR. RESULTS: Two homozygous mutations (p.R391S and p.H397P), both in exon 9 of the VDR gene, were identified. Phenotype/genotype association was not possible even for the same mutation. Alopecia was seen only with the p.R391S mutation. Despite a comparable rachitic bone disease, the patients showed different responsiveness to large doses of alfacalcidol (1-α-hydroxy vitamin D3) supplementation. CONCLUSIONS: This is the first report of VDR mutations in Lebanon with promising clinical outcomes despite the severity of the phenotypes.

Research in congenital heart disease: a comparative bibliometric analysis between developing and developed countries.

Congenital heart disease (CHD) is the most common congenital anomaly, affecting 1 % of live births. The field of pediatric cardiology has witnessed major advances over the past 25 years triggered by research initiatives focusing on CHD. However, large disparities exist in research capabilities between Arab developing nations and the developed nations. This study used bibliometric analysis to assess the contribution of the Arab countries to CHD research. To identify articles on CHD published in the Arab countries, the United States, and Europe, a systematic search was run on MEDLINE, PubMed, and Scopus. The Arab countries, with an estimated population of 362 million, published 530 research articles addressing CHD in the last 25 years (average, 1.5 articles/10(6) population). This compares with 12,936 research articles published in the United States (average, 41 articles/10(6) population) and 12,260 published in Europe (average, 24.3 articles/10(6) population). Basic research relating to genetics and animal models of CHD is emerging sparsely in the Arab world, with few articles published in high-impact-factor journals. The Arab world research output in the field of CHD per capita is substantially low, estimated to be 29 times less than in developed countries. Despite the minimal increase in published research articles in global periodicals, most of the research relating to CHD continues to be far from innovative. Regional collaborations with international linkage are starting to evolve. The research facilities in the Arab countries need to increase substantially in research and infrastructure funding to keep up with the pace of research in developing countries.

Diet, genetics, and disease: a focus on the middle East and north Africa region.

The Middle East and North Africa (MENA) region suffers a drastic change from a traditional diet to an industrialized diet. This has led to an unparalleled increase in the prevalence of chronic diseases. This review discusses the role of nutritional genomics, or the dietary signature, in these dietary and disease changes in the MENA. The diet-genetics-disease relation is discussed in detail. Selected disease categories in the MENA are discussed starting with a review of their epidemiology in the different MENA countries, followed by an examination of the known genetic factors that have been reported in the disease discussed, whether inside or outside the MENA. Several diet-genetics-disease relationships in the MENA may be contributing to the increased prevalence of civilization disorders of metabolism and micronutrient deficiencies. Future research in the field of nutritional genomics in the MENA is needed to better define these relationships.
