Risk Stratification Algorithm for Orthopedic Trauma Patients at Risk for Fat Embolism Syndrome.

BACKGROUND: Fat embolism syndrome (FES) is commonly reported in the setting of long bone and pelvic fractures, but the etiology and pathogenesis are unclear. The aim of this study was to identify clinical characteristics and laboratory findings that may place orthopedic trauma patients at a higher risk of developing FES. METHODS: Electronic medical records were reviewed of all patients aged 18-89 years from 2015 to 2020 with a mention of FES in the patient chart who met Gurd and Wilson's criteria for diagnosis after experiencing orthopedic trauma. A 3:1 matched pair analysis was performed between FES patients and those with similar age, gender, and FES-associated fracture (femur, tibia, humerus, or pelvis fracture). RESULTS: 18 patients with FES who met inclusion criteria were identified. Hypomagnesemia (OR = 7.43), hyperphosphatemia (OR = 6.24), hypoalbuminemia (OR = 3.78), blunt traumatic mechanism of injury (OR = 7.16) and a greater number of bones fractured (Avg/SD = 2.89/1.53) were seen more often in FES patients (all p-values < 0.05). CONCLUSION: Findings of this study suggest that patients with hypomagnesemia, hyperphosphatemia, hypoalbuminemia, a blunt trauma mechanism of injury, and an increased number of bones fractured are at increased risk for the development of FES. This may be related to their roles in physiologic oncotic pressure and inflammatory response, and thus further investigation of these variables is necessary for the evaluation of FES prevention. LEVEL OF EVIDENCE: Level 3.

Prevalence of Venous Thromboembolism Following Acute Spinal Cord Injury in an Urban Inner City Hospital.

BACKGROUND: Venous thromboembolism (VTE) is known to occur at high rates in patients who suffer spinal cord injury (SCI). Large population studies in the United States have shown a prevalence of approximately 4-5%, with some studies suggesting higher prevalence. While the specific mechanism behind increased VTE incidence in the SCI population is unknown, it is likely tied to immobility and functional decline. Previous studies have also linked social determinants of health to higher VTE prevalence in certain populations. The purpose of this study is to determine the prevalence of VTE after acute SCI in the inner urban city population and to identify factors that place patients at increased VTE risk. METHODS: Patients who suffered SCI between 2014 and 2019 were identified from one inner city urban hospital. A retrospective chart review was completed to record the development of VTE after SCI. Medical comorbidities, type of thromboprophylaxis used, patient demographics, injury characteristics, and postinjury sequelae were compared between individuals who did and did not develop VTE. RESULTS: A total of 148 patients were included. These patients were from a low socioeconomic demographic when compared with the larger US population. Average household income based on zip code data for included patients was $56 647, $30 315 below the national average. The prevalence of VTE in this patient population was 19.59%. Weight, deep vein thrombosis history, chemoprophylaxis use, mobility impairment postinjury, neurologic level of SCI, malignancy history, and history of smokeless tobacco were associated with VTE (all P < .05). Low molecular weight heparin (LMWH) use was associated with fewer occurrences of VTE (P < .001). CONCLUSION: Patients from our urban inner city hospital have a higher VTE prevalence after SCI than shown in previous US-based studies. These patients may be at increased risk due to increased numbers of medical comorbidities, social factors, or undiagnosed medical conditions. Thromboprophylaxis with LMWH appears to lower the risk of VTE after SCI. LEVEL OF EVIDENCE: 3. CLINICAL RELEVANCE: Patients with the previously mentioned risk factors are at increased risk for VTE development during their acute recovery process. These patients should have a much lower screening threshold for VTE evaluation and likely would benefit from more routine screening to prevent complications related to VTE development or progression. Furthermore, these patients should, when medically appropriate, be treated with low molecular weight heparin for VTE prophylaxis as previously recommended by the Consortium for Spinal Cord Medicine.

Health needs of refugee children identified on arrival in reception countries: a systematic review and meta-analysis.

BACKGROUND: The worldwide number of refugees has considerably increased due to ongoing wars, national instability, political persecution and food insecurity. In Europe, about one-third of all refugees are children, an increasing number of which are travelling alone. There are often no systematic medical health assessments for these refugee children on entry in reception countries despite the fact that they are recognised as an at-risk population due to increased burden of physical and mental health conditions. We aimed to perform a systematic review of the literature to describe the health status of refugee children on entering reception countries. METHODS: A systematic search of published literature was conducted using the terms refugee, immigrant or migrant, medical or health, and screening. RESULTS: Of the 3487 potentially relevant papers, 53 population-based studies were included in this review. This systematic review showed that refugee children exhibit high estimated prevalence rates for anaemia (14%), haemoglobinopathies (4%), chronic hepatitis B (3%), latent tuberculosis infection (11%) and vitamin D deficiency (45%) on entry in reception countries. Approximately one-third of refugee children had intestinal infection. Nutritional problems ranged from wasting and stunting to obesity. CONCLUSIONS: Refugee children entering reception countries should receive comprehensive health assessments based on the outcomes of this systematic review, national budgets, cost-effectiveness and personal factors of the refugees. The health assessment should be tailored to individual child health needs depending on preflight, flight and postarrival conditions.A paradigm shift that places focus on child health and development will help this vulnerable group of children integrate into their new environments.
