RESUMEN
Syrian hamsters (Mesocricetus auratus) have been increasingly used as rodent models in recent years, especially for SARS-CoV-2 since the pandemic. However, the physiology of this animal model is not yet well-understood, even less when considering the digestive tract. Generally, the gastrointestinal microbiome influences the immune system, drug metabolism, and vaccination efficacy. However, a detailed understanding of the gastrointestinal microbiome of hamsters is missing. Therefore, we analyzed 10 healthy 11-week-old RjHan:AURA hamsters fed a pelleted standard diet. Their gastrointestinal content was sampled (i.e., forestomach, glandular stomach, ileum, cecum, and colon) and analyzed using 16S rRNA gene amplicon sequencing. Results displayed a distinct difference in the bacterial community before and after the cecum, possibly due to the available nutrients and digestive functions. Next, we compared hamsters with the literature data of young-adult C57BL/6J mice, another important animal model. We sampled the same gastrointestinal regions and analyzed the differences in the microbiome between both rodents. Surprisingly, we found strong differences in their specific gastrointestinal bacterial communities. For instance, Lactobacillaceae were more abundant in hamsters' forestomach and ileum, while Muribaculaceae dominated in the mouse forestomach and ileum. Similarly, in mouse cecum and colon, Muribaculaceae were dominant, while in hamsters, Lachnospiraceae and Erysipelotrichaceae dominated the bacterial community. Molecular strains of Muribaculaceae in both rodent species displayed some species specificity. This comparison allows a better understanding of the suitability of the Syrian hamster as an animal model, especially regarding its comparability to other rodent models. Thereby, this work contributes to the characterization of the hamster model and allows better experimental planning.
RESUMEN
Dental age assessment based on evaluating dental mineralization status is one of the most common methods used in forensic practice. The aim of this study is to enhance the accuracy of age diagnostics and provide reference data from the Syrian population for forensic application. After several selection steps, a total of 280 orthopantomograms (OPGs) from 140 males and 140 females from the Syrian population divided into 14 age groups between 12 and 25 years were analysed. Based on Demirjian's classification system, the mineralization stages of third molars (18, 28, 38 and 48) as well as lower second molars (37 and 47) were evaluated. Statistical investigations and evaluations were carried out to estimate the marginal probabilities of the subjects having attained ages 14 and 18 by generalized estimating equation models. Our results show that no significant differences can be revealed in the mineralization status with respect to jaw side and sex. In the Syrian population, third molars showing mineralization stage G provide evidence of reaching the age of 14 years with the highest standard of proof ("beyond reasonable doubt"). A completed mineralization in lower second molars (stage H) provides very high marginal probabilities (more than 90%) of the subjects having attained age 14 years. Nevertheless, this cannot exclude an age under 14 years. For the age threshold of 18 years, third molars showing incomplete root development (G dental stage or lower) are associated with a low probability (less than 40%) of the subject having reached 18 years of age. A person's probability of having attained 18 years of age is very high (82- 95%) when the roots of third molars are fully developed (stage H). Nevertheless, third molars at stage H do not conclusively exclude an age under 18 years.
RESUMEN
Syrian hamsters are valuable models for studying lipid metabolism due to their sensitivity to dietary cholesterol, yet the precise impact of varying cholesterol levels has not been comprehensively assessed. This study examined the impact of varying dietary cholesterol levels on lipid metabolism in Syrian hamsters. Diets ranging from 0% to 1% cholesterol were administered to assess lipid profiles and oxidative stress markers. Key findings indicate specific cholesterol thresholds for inducing distinct lipid profiles: below 0.13% for normal lipids, 0.97% for elevated LDL-C, 0.43% for increased VLDL-C, and above 0.85% for heightened hepatic lipid accumulation. A cholesterol supplementation of 0.43% induced hypercholesterolemia without adverse liver effects or abnormal lipoprotein expression. Furthermore, cholesterol supplementation significantly increased liver weight, plasma total cholesterol, LDL-C, and VLDL-C levels while reducing the HDL-C/LDL-C ratio. Fecal cholesterol excretion increased, with stable bile acid levels. High cholesterol diets correlated with elevated plasma ALT activities, reduced hepatic lipid peroxidation, and altered leptin and CETP levels. These findings underscore Syrian hamsters as robust models for hyperlipidemia research, offering insights into experimental methodologies. The identified cholesterol thresholds facilitate precise lipid profile manipulation, enhancing the hamster's utility in lipid metabolism studies and potentially informing clinical approaches to managing lipid disorders.

BACKGROUND: Although Türkiye (Turkey) hosts the largest number of Syrian refugees, studies on food insecurity are limited. This study examined the prevalence and risk factors of food insecurity among Syrian refugees living in Istanbul, which has the highest number of refugees in Türkiye. METHODS: A cross-sectional survey was conducted among Syrian refugees in Istanbul between September 2021 and March 2022. The main income earners of 103 households were interviewed by a research dietitian, with the assistance of an Arabic speaking interpreter through hour-long face-to-face. Data on sociodemographic characteristics (age, gender, nationality, marital status, educational status, the family income, the major source of family income, and the number of family members living in the household etc.) and household food insecurity status were collected. Household food insecurity status was assessed with the eighteen-item Household Food Security Survey Module. RESULTS: The household food insecurity rate was 90.3%, and those of adults and children were 88.4% and 84.8%, respectively. It was observed that family income level was significantly associated with food insecurity. A one-unit increase in monthly income increased food security by 0.02 times (p < 0.001). The number of employed refugees in the food security group was higher than that in the food insecurity group (p = 0.018). A significant difference was found in the rate of occupation type of the major income earner between the groups (p = 0.046). CONCLUSIONS: High rates of food insecurity, particularly severe food insecurity, were found among Syrian refugees living in Istanbul. While more research is warranted to explore the root causes and efficacy of the current support system, it requires the immediate attention of policymakers at the national and international levels to implement effective policies and interventions.

BACKGROUND: Medical research productivity is globally increasing, with a lagging progress in third-world countries due to significant challenges, including inadequate training and brain drain. Syria had been showing a slow upward trend until the war broke out and severely hindered academic growth and productivity. A deeper understanding of the factors influencing research productivity in this context are fundamental to guide educational policies and resource allocation. Previous cross-sectional studies that evaluated the perspectives of Syrian academics on the issue were limited by the small sample size of published healthcare workers, making it difficult to identify the factors that enabled them to pursue research. METHODS: To address this challenge, we employed a case-control design. We isolated published early-career Syrian healthcare workers and compared their characteristics and perceptions to unpublished matched controls. Authors in the fields of medicine, dentistry, and pharmacy affiliated with any Syrian University were identified through an extensive search of PubMed and Google Scholar.These authors were invited to complete a questionnaire that covered participants' research contributions, alongside their self-assessed knowledge, attitudes, and barriers towards research. The questionnaire was publicly published to recruit an equal sample of matching controls, with half consisting of unpublished researchers and the other half of participants without prior research contributions. RESULTS: Six-hundred-sixteen participants were recruited. Their knowledge, attitudes, and perceived barriers explained 46% and 34% of the variability in research involvement and publication, respectively (P < 0.001). Getting involved in and publishing research studies associated with higher research-related knowledge and attitudes (P < 0.001). Respondents' assessment of research-related barriers and their academic scores did not differ between cases and controls. Superior research-related knowledge and attitudes were associated with male gender, higher English competency, and better internet connectivity. Meanwhile, extracurricular training and mentors' support were associated with more positive research-related attitudes and less perceived barriers. CONCLUSIONS: Research productivity of medical professionals in Syria exhibits a positive correlation with their knowledge and favorable attitudes towards medical research. Noteworthy, the demographic variations are linked to disparities in research-related knowledge and motivation. In conclusion, these results suggest a potential avenue for enhancement through concentrated efforts on improving extracurricular training interventions and mentors' support.

Introduction: After the war in Syria, many people were forcibly displaced, and many others migrated to foreign countries. Many Syrians have been exposed to traumatic negative lifeexperiences during this process. In this context, this study was carried out to investigate the effects of pre- and post-migration traumatic experiences and living difficulties on the development of post-traumatic stress disorder (PTSD) in Syrian refugees who have been residing in Turkey for more than five years. Methods: The sample size of this cross-sectional study consisted of 200 Syrian refugees. Research data were collected using a self-report questionnaire. Refugees' depression and anxiety levels were assessed with The Hopkins Symptom Checklist-25 (HSCL-25), and post-traumatic stress disorder (PTSD) symptoms were assessed with the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) (PCL-5). Logistic regression models were created to assess the effects of pre- and post-migration traumas, adverse events, and other sociodemographic variables, including age and gender, on PTSD. Results: The study unveiled a high prevalence of PTSD (55.5%), depression (33.5%), and anxiety(4.5%) among participants. Notably, male refugees and those exposed to armed conflict exhibited a significantly higher frequency of PTSD. In contrast, depression was more prevalent among female participants. Pre-migration traumatic experiences, especially near-death situations, were identified as significant predictors of PTSD. Interestingly, while pre-migration traumatic experiences were higher, post-migration living difficulties also emerged as a concern, with factorslike "inability to return home in emergencies" and "worries about losing ethnic identity" beinghighlighted. Path analysis further revealed that pre-migration traumatic experiences indirectly contributed to PTSD by exacerbating post-migration living difficulties. Discussion: Syrian refugees in Turkey, even after long-term residence, exhibit high rates of PTSD, depression, and anxiety. While pre-migration traumas play a pivotal role, post-migration challenges further compound their mental health issues. These findings underscore the need for holistic, long-term mental health interventions that address both past traumas and current living difficulties.
RESUMEN
Background: Several learning modalities have been implemented to improve learning about Traumatic Dental Injuries (TDIs) worldwide. Free online courses about TDIs might be an effective and convenient approach for equipping Syrian dentists with essential competencies during the Syrian crisis. Therefore, this qualitative study with a descriptive phenomenological method was undertaken to explore the lived experience of Syrian dentists enrolled in an online course about TDIs and investigate areas requiring improvement. Methods: Ethical approval was obtained from the Faculty of Dentistry, Damascus University, and the University of Dundee. Educational contents of the TDI course were developed. About 10 dentists who completed the TDI course, were interviewed. The interviews were recorded, transcribed, and analyzed to identify emerging themes. Inductive thematic analysis was performed to extract all data. Results: About 10 clustered categories were first developed and this has led to the emergence of 3 themes that represent the lived experience including usefulness, challenges, and recommendations. Participants were so motivated and keen to take advantage of the course despite the personal, technical problems, and crisis-related challenges. TDIs course was effective for general and specialists despite the challenges they experienced. Factors that lead to effective TDIs courses as reported by participants were flexibility in time and location, interactivity with colleagues, other commitments, quantity and quality of content, easiness, and variety of virtual environment tools. Conversely, negative attitudes were linked to factors like lack of interest, unfamiliarity with the learning environment and tools, late participation, lack of confidence, anxiety about independent learning and insufficient interactivity and engagement tools. Conclusion: Syrian dentists can benefit from online courses if constraints and various learning needs are addressed during the design and delivery of online courses. Future work is still required to identify other effective instructional modalities that equip Syrian dentists to overcome challenges and enhance their learning.
RESUMEN
Background and Aim: With the emergence of severe acute respiratory syndrome-related coronavirus (SARS-CoV-2), antiviral drug development has gained increased significance due to the high incidence and potentially severe complications of the resulting coronavirus infection. Heterocycle compounds, acting as antimetabolites of DNA and RNA monomers, rank among the most effective antiviral drugs. These compounds' antiviral effects on various SARS-CoV-2 isolates, as found in existing data collections, form the basis for further research. The aim of this study was to examine the possible antiviral effect of some originally synthesized heterocyclic compounds. Materials and Methods: The main methods were cell culturing, cytotoxicity assay, qRT-PCR assay, tissue and blood cells analysis, and micro-computed tomography (micro-CT) imaging. Results: In both in vitro and in vivo conditions, the elimination of SARS-Cov-2 occurred significantly earlier after administration of the compounds compared to the control group. In hamsters, the primary symptoms of coronavirus disease disappeared following administration of heterocycle compounds. Conclusion: Using delta and omicron strains of the SARS-CoV-2 virus, newly created heterocycle compound analogs dramatically reduced SARS-CoV-2 multiplication, resulting in a drop in viral RNA load in the supernatant under in vitro conditions. Improvements in pathological manifestations in the blood, bone marrow, and internal organs of hamsters demonstrated that heterocycle compounds inhibited SARS-CoV-2 replication both in vitro and in vivo.
RESUMEN
Pulmonary function examinations are critical to assess respiratory disease severity in patients. In preclinical rodent models of viral respiratory infections, however, disease is frequently evaluated based on virological, pathological and/or surrogate clinical parameters, which are not directly associated with lung function. To bridge the gap between preclinical and clinical readouts, we aimed to apply unrestrained whole-body plethysmography (WBP) measurements in a SARS-CoV-2 Syrian hamster challenge model. While WBP measurements are frequently used for preclinical research in mice and rats, results from studies in hamsters are still limited. During unrestrained WBP measurements, we obtained highly variable breathing frequency values outside of the normal physiological range for hamsters. Importantly, we observed that animal movements were recorded as breaths during WBP measurements. By limiting animal movement through either mechanical or chemical restraint, we improved the reliability of the lung function readout and obtained breathing frequencies that correlated with clinical signs when comparing two different variants of SARS-CoV-2 post-inoculation. Simultaneously, however, new sources of experimental variation were introduced by the method of restraint, which demands further optimalization of WBP measurements in Syrian hamsters. We concluded that WBP measurements are a valuable refinement either in combination with video recordings or if average values of measurements lasting several hours are analyzed.

Equid alphaherpesvirus 1 (EqAHV1) is a viral pathogen known to cause respiratory disease, neurologic syndromes, and abortion storms in horses. Currently, there are no vaccines that provide complete protection against EqAHV1. Marker vaccines and the differentiation of infected and vaccinated animals (DIVA) strategy are effective for preventing and controlling outbreaks but have not been used for the prevention of EqAHV1 infection. Glycoprotein 2 (gp2), located on the envelope of viruses (EqAHV1), exhibits high antigenicity and functions as a molecular marker for DIVA. In this study, a series of EqAHV1 mutants with deletion of gp2 along with other virulence genes (TK, UL24/TK, gI/gE) were engineered. The mutant viruses were studied in vitro and then in an in vivo experiment using Golden Syrian hamsters to assess the extent of viral attenuation and the immune response elicited by the mutant viruses in comparison to the wild-type (WT) virus. Compared with the WT strain, the YM2019 Δgp2, ΔTK/gp2, and ΔUL24/TK/gp2 strains exhibited reduced growth in RK-13 cells, while the ΔgI/gE/gp2 strain exhibited significantly impaired proliferation. The YM2019 Δgp2 strain induced clinical signs and mortality in hamsters. In contrast, the YM2019 ΔTK/gp2 and ΔUL24/TK/gp2 variants displayed diminished pathogenicity, causing no observable clinical signs or fatalities. Immunization with nasal vaccines containing YM2019 ΔTK/gp2 and ΔUL24/TK/gp2 elicited a robust immune response in hamsters. In particular, compared with the vaccine containing the ΔTK/gp2 strain, the vaccine containing the ΔUL24/TK/gp2 strain demonstrated enhanced immune protection upon challenge with the WT virus. Furthermore, an ELISA for gp2 was established and refined to accurately differentiate between infected and vaccinated animals. These results confirm that the ΔUL24/TK/gp2 strain is a safe and effective live attenuated vaccine candidate for controlling EqAHV1 infection.

In this study, we investigated the features of co-infection with SARS-CoV-2 and the enterovirus vaccine strain LEV8 of coxsackievirus A7 or enterovirus A71 for Vero E6 cells and Syrian hamsters. The investigation of co-infection with SARS-CoV-2 and LEV-8 or EV-A71 in the cell model showed that a competitive inhibitory effect for these viruses was especially significant against SARS-CoV-2. Pre-infection with enteroviruses in the animals caused more than a 100-fold decrease in the levels of SARS-CoV-2 virus replication in the respiratory tract and more rapid clearance of infectious SARS-CoV-2 from the lower respiratory tract. Co-infection with SARS-CoV-2 and LEV-8 or EV-A71 also reduced the severity of clinical manifestations of the SARS-CoV-2 infection in the animals. Additionally, the histological data illustrated that co-infection with strain LEV8 of coxsackievirus A7 decreased the level of pathological changes induced by SARS-CoV-2 in the lungs. Research into the chemokine/cytokine profile demonstrated that the studied enteroviruses efficiently triggered this part of the antiviral immune response, which is associated with the significant inhibition of SARS-CoV-2 infection. These results demonstrate that there is significant viral interference between the studied strain LEV-8 of coxsackievirus A7 or enterovirus A71 and SARS-CoV-2 in vitro and in vivo.

Cold and ischemia/reperfusion (IR)-associated injuries are seemingly inevitable during liver transplantation and hepatectomy. Because Syrian hamsters demonstrate intrinsic tolerance to transplantation-like stimuli, cross-species comparative metabolomic analyses were conducted with hamster, rat, and donor liver samples to seek hepatic cold and IR-adaptive mechanisms. Lower hepatic phosphocholine contents were found in recipients with early graft-dysfunction and with virus-caused cirrhosis or high model for end-stage liver disease scores (≥30). Choline/phosphocholine deficiency in cultured human THLE-2 hepatocytes and animal models weakened hepatocellular cold tolerance and recovery of glutathione and ATP production, which was rescued by phosphocholine supplements. Among the biological processes impacted by choline/phosphocholine deficiency, 3 lipid-related metabolic processes were downregulated, whereas phosphocholine elevated the expression of genes in methylation processes. Consistently, in THLE-2, phosphocholine enhanced the overall RNA m6A methylation, among which the transcript stability of fatty acid desaturase 6 (FADS6) was improved. FADS6 functioned as a key phosphocholine effector in the production of polyunsaturated fatty acids, which may facilitate the hepatocellular recovery of energy and redox homeostasis. Thus, our study reveals the choline-phosphocholine metabolism and its downstream FADS6 functions in hepatic adaptation to cold and IR, which may inspire new strategies to monitor donor liver quality and improve recipient recovery from the liver transplantation process.
RESUMEN
It is aimed to examine the frequency of COVID-19 disease, the rates of COVID-19 vaccination and the vaccine effectiveness (VE) among Syrian refugees. It is a retrospective cohort study. Syrian refugees aged 18 years and above registered to a family health center in Sultanbeyli district in Istanbul were included. Vaccine effectiveness were calculated for both Pfizer BioN-Tech and CoronaVac (Sinovac) vaccines. The data of 2586 Syrian people was evaluated in the study. The median age of the participants was 34.0 years (min:18.0; max: 90.0). Of the participants 58.4% (n = 1510) were female, 41.6% (n = 1076) were male. In our study of the refugees 15.7% had history of COVID-19 infection. Refugees having full vaccination with Biontech and Sinovac have a significantly lower COVID-19 infection rate than those without vaccination (HR = 8.687; p < 0.001). Adjusted VE for Biontech, Sinovac, and both were 89.2% (95.0% CI:83.3-93.1), 81.2% (95.0% CI:48.72-93.1) and 88.5% (95.0% CI:82.7-92.3), respectively. The results of the study highlight the importance of vaccinations against COVID-19 pandemic, since both vaccines were highly protective in refugees.

Gender-based violence (GBV), a global health and human rights concern, often intensifies during emergencies. This paper explores the evolution of GBV coordination in Lebanon's protracted Syrian refugee crisis from 2012-22. Utilising 38 in-depth interviews and a document review, the findings were analysed using the framework for effective GBV coordination. Lebanon provides a positive yet complicated example of GBV coordination. Initially established to address the refugee crisis, it matured into a collaborative national coordination mechanism, fostering trust and advancing localisation amidst sectarian complexities. However, the volatile, restrictive policy context hindered government co-leadership and engagement with refugee-led organisations. While essential GBV response services were expanded nationwide, lack of an interagency strategy on GBV risk mitigation and prevention compromised lasting change. The paper emphasises the importance of dedicated GBV coordinators, multi-year funding, and increased attention to GBV prevention. The findings underscore the transformative potential of humanitarian responses and advocate for enhanced engagement with national stakeholders to promote sustainability in protracted crises.
RESUMEN
Background: Measles is reemerging as a public health threat, raising important questions about disease vulnerability among childhood cancer survivors. This secondary analysis assessed the seroprevalence of anti-measles immunoglobulin G (IgG) antibodies as a marker of immune status in survivors of childhood cancer and associated demographic/treatment variables. Method: Participants were childhood cancer survivors who were free of active disease, having routine blood studies drawn, and could provide documentation of having received two doses of measles, mumps, and rubella vaccine before their cancer diagnosis. Patient record review documented demographic and treatment variables. Antimeasles (rubeola) IgG antibody seroprevalence was assessed by enzyme immunoassay for vaccine-specific antibodies. Results: Of 270 survivors evaluated, 110 (42%) were female, 196 (75%) were White, and 159 (61%) were leukemia/lymphoma survivors. Of these 262, 110 (42%) had negative measles seroprevalence, suggesting loss of immunity. Conclusion: Measles antibody surveillance and the need for reimmunization for survivors of childhood cancer survivors outside the transplant setting remains controversial. Our analysis indicates that a substantial proportion of survivors lose vaccine-related immunity to measles. Pediatric oncology nurses play important roles in educating cancer survivors regarding their risk of measles infection, evaluating the need for reimmunization, correcting misinformation about vaccine safety and effectiveness, and working to optimize community herd-based immunity.
RESUMEN
BACKGROUND: There is evidence from meta-analyses and systematic reviews that digital mental health interventions for depression, anxiety, and stress-related disorders tend to be cost-effective. However, no such evidence exists for guided digital mental health care in low and middle-income countries (LMICs) facing humanitarian crises, where the needs are highest. Step-by-Step (SbS), a digital mental health intervention for depression, anxiety, and stress-related disorders, proved to be effective for Lebanese citizens and war-affected Syrians residing in Lebanon. Assessing the cost-effectiveness of SbS is crucial because Lebanon's overstretched health care system must prioritize cost-effective treatment options in the face of continuing humanitarian and economic crises. OBJECTIVE: This study aims to assess the cost-effectiveness of SbS in a randomized comparison with enhanced usual care (EUC). METHODS: The cost-effectiveness analysis was conducted alongside a pragmatic randomized controlled trial in 2 parallel groups comparing SbS (n=614) with EUC (n=635). The primary outcome was cost (in US $ for the reference year 2019) per treatment response of depressive symptoms, defined as >50% reduction of depressive symptoms measured using the Patient Health Questionnaire (PHQ). The secondary outcome was cost per remission of depressive symptoms, defined as a PHQ score <5 at last follow-up (5 months post baseline). The evaluation was conducted first from the health care perspective then from the societal perspective. RESULTS: Taking the health care perspective, SbS had an 80% probability to be regarded as cost-effective compared with EUC when there is a willingness to pay US $220 per additional treatment response or US $840 per additional remission. Taking the wider societal perspective, SbS had a >75% probability to be cost-saving while gaining response or remission. CONCLUSIONS: To our knowledge, this study is the first cost-effectiveness analysis based on a large randomized controlled trial (n=1249) of a guided digital mental health intervention in an LMIC. From the principal findings, 2 implications flowed, from the (1) health care perspective and (2) wider societal perspective. First, our findings suggest that SbS is associated with greater health benefits, albeit for higher costs than EUC. It is up to decision makers in health care to decide if they find the balance between additional health gains and additional health care costs acceptable. Second, as seen from the wider societal perspective, there is a substantial likelihood that SbS is not costing more than EUC but is associated with cost-savings as SBS participants become more productive, thus offsetting their health care costs. This finding may suggest to policy makers that it is in the interest of both population health and the wider Lebanese economy to implement SbS on a wide scale. In brief, SbS may offer a scalable, potentially cost-saving response to humanitarian emergencies in an LMIC.

This article examines the dynamic relationship between the creation of place and the formation of identity, specifically focusing on how Syrian young people are either included or excluded in Istanbul. This dynamic process enables the students to engage in placemaking. The majority of the literature primarily centres on the potential for inclusion or exclusion within the context of migration. Nevertheless, I maintain my view that the dynamics between insiders and outsiders are closely interconnected in discourses about space. In this regard, it is worth exploring how the concept of Thirdspace enables the coexistence of both inclusion and exclusion within the same spatial context. Based on ethnographic observations, virtual ethnographies, and semi-structured interviews conducted with 30 Syrian students, I employ the notions of "social imaginary" and "emotional space" to demonstrate the coexistence of contrasting elements inside a shared location. While I utilised a framework that integrated geographical and sociological perspectives for my study, the unique aspect of this research lies in its adoption of the socio-spatiality approach, setting it apart from prior studies. While this approach opens space to the possibility of the simultaneous exclusionary and inclusionary functions of the spaces, the translocational positionality of the migrant groups fosters these contradictory interactions in the shared spaces. Gender differences and ethnicity (being Syrian) produce exclusionary functions, whereas being a student and Muslim increases integration into Turkish society. In addition to interactions within local relationships and transnational connections through religious communities, NGOs, and friend groups, these students not only resolve the tension between the past and present but also open the door to integration and bridge the future in the face of inequalities. In particular, women students solve the tension between cultural codes and their student identity with the possibility of transnational networks.
RESUMEN
Despite the increased heterogeneity of living conditions of refugees in recent years, there is a lack of robust epidemiological data about the relationship between refugees' mental health and their living contexts. The current study aims to compare frequencies of pre-migration traumatic events and post-migration difficulties between refugees living in camps and those living in cities; and to identify the prevalence of post-traumatic stress disorder (PTSD), depression, and factors associated with them. A field survey was conducted among 1,470 refugees living in camps and urban settings of Turkey. The survey instruments included a socio-demographic form, the Harvard Trauma Questionnaire, the Post-migration Living Difficulties Scale, and the PTSD and depression modules of the Mini-International Neuropsychiatric Interview. Both PTSD and depression were more common in urban settings than in camps. Both disorders were associated with living context and migration-related experiences. Pre-migration traumas were more frequent among refugees living in cities than in those living in camps, while post-migration difficulties were more common in the refugees living in camps. The living context is potentially a critical determinant of refugee mental health. Camp and urban refugees may have different experiences and needs. In particular, refugees living in some urban settings may be at higher risk for having psychological problems.
RESUMEN
BACKGROUND: Thromboelastography (TEG) is a widely utilized clinical testing method for real-time monitoring of platelet function and the thrombosis process. Lipid metabolism disorders are crucial risk factors for thrombosis. The lipid metabolism characteristics of hamsters resemble those of humans more closely than mice and rats, and their relatively large blood volume makes them suitable for studying the mechanisms of thrombosis related to plasma lipid mechanisms. Whole blood samples from golden Syrian hamsters and healthy humans were obtained following standard clinical procedures. TEG was employed to evaluate coagulation factor function, fibrinogen (Fib) function, platelet function, and the fibrinolytic system. METHODS: The whole blood from hamster or healthy human was isolated following the clinical procedure, and TEG was employed to evaluate the coagulation factor function, Fib function, platelet function, and fibrinolytic system. Coagulation analysis used ACLTOP750 automatic coagulation analysis pipeline. Blood routine testing used XN-2000 automatic blood analyzer. RESULTS: TEG parameters revealed that hamsters exhibited stronger coagulation factor function than humans (reaction time [R], p = 0.0117), with stronger Fib function (alpha angle, p < 0.0001; K-time [K], p < 0.0001). Platelet function did not differ significantly (maximum amplitude [MA], p = 0.077). Hamsters displayed higher coagulation status than humans (coagulation index [CI], p = 0.0023), and the rate of blood clot dissolution in hamsters differed from that in humans (percentage lysis 30 min after MA, p = 0.02). Coagulation analysis parameters indicated that prothrombin time (PT) and activated partial thromboplastin time (APTT) were faster in hamsters than in humans (PT, p = 0.0014; APTT, p = 0.03), whereas the Fib content was significantly lower in hamsters than in humans (p < 0.0001). No significant difference was observed in thrombin time (p = 0.1949). CONCLUSIONS: In summary, TEG could be used to evaluate thrombosis and bleeding parameters in whole blood samples from hamsters. The platelet function of hamsters closely resembled that of humans, whereas their coagulation function was significantly stronger.
RESUMEN
In conflict zones like Syria, accessing specialized medical care presents significant challenges. Here, we present the case of a 22-year-old female with a giant cell tumor in her distal forearm, exacerbated by limited access to healthcare due to the Syrian conflict. Despite these obstacles, we successfully performed en bloc resection and reconstructed the defect with a proximal non-vascularized fibular graft, restoring arm function. This case underscores the critical importance of adapting to adverse circumstances to deliver essential medical interventions in conflict-affected regions.
