VP20.12 : Lymphangioma : fetal neck mass, delivery of pregnancy through EXIT technique – case report, University Hospital San Ignacio (HUSI)
Q1Lymphangioma is a rare type of benign tumour, caused by a lack of development of the lymphatic's system components. This malformation is an accumulation of fluid mainly located in the posterolateral region of the neck in 75% of cases, followed by armpit 20%, mediastinum 1%, abdominal organs, mesenteric retroperitoneal in 2–3% & bone, lower limbs in 2%. This develops in the second and third trimester. It could be aggressive due to the infiltration in adjacent tissues or closer organs, additionally, it could be associated with chromosomal abnormalities or other malformations, basically, the prognosis depends weather it is present or not. In isolated forms, these tumours have a good prognosis. In cases where the malformation is found on the neck in the first trimester, the assessment, behaviour, name, management and etiology could be different and it is called increased NT. The prenatal management includes serial ultrasound in maternal-fetal unit, karyotyping, MRI to see the level of infiltration and the associated airway obstruction, and multidisciplinary team experienced in airways management. In cases of cervical lymphangiomas, the gestation delivery should be done by a Caesarean section (CS) with an EXIT technique in order to guarantee the fetal airway before separation of the maternal-fetal circulation. it is imperative to set up the procedure through a multidisciplinary team meeting, in order to assign each of the roles in surgery and to know the additional materials or procedures in accordance with the fetal airway compromise. In this case the diagnosis was confirmed by maternal medicine team as a cervical lymphangioma in the HUSI in Bogotá through US performed on the 34.5 week. Additionally, we used an MRI to assess the fetal airway and after words we booked meetings with an interdisciplinary team with the objective of planning the procedures and materials required during the delivery through a CS with an EXIT technique, following the institutional protocols.Revista Internacional - Indexad

Waste Crime: Low Risks - High Profits. Gaps in Meeting the Global Waste Challenge. A Rapid Reponse Assessment
More than ever, our future depends upon how we manage the future of our waste. As an integrated part of sustainable development, effective waste management can reduce our global footprint. Ignoring or neglecting the challenges of waste, however, can lead to significant health, environmental and economic consequences. A staggering 1.3 billion tonnes of food is produced each year to feed the world’s 7 billion people. Yet, according to the Food and Agriculture Organization (FAO), around US$1 trillion of that food goes to waste. With 200,000 new people added every day, the world can ill afford to waste such a massive amount of food. Global waste, however, does not stop at food. Consumers are increasingly buying products that are wrapped in plastics and paper. Much of this packaging – and eventually the products themselves – will end up in landfills. This trend has both health and environmental consequences, especially given the rapid rise of hazardous waste such as electronics
Validation of a Length-Adjusted Abdominal Arterial Calcium Score Method for Contrast-Enhanced CT Scans
BACKGROUND: The Agatston score on noncontrast computed tomography (CT) scans is the gold standard for calcium load determination. However, contrast-enhanced CT is commonly used for patients with atherosclerotic cardiovascular diseases (ASCVDs), such as peripheral arterial occlusive disease (PAOD) and abdominal aortic aneurysm (AAA). Currently, there is no validated method to determine calcium load in the aorta and peripheral arteries with a contrast-enhanced CT. This study validated a length-adjusted calcium score (LACS) method for contrast-enhanced CT scans.METHOD: The LACS (calcium volume in mm 3/arterial length in cm) in the abdominal aorta was calculated using four-phase liver CT scans of 30 patients treated between 2017 and 2021 at the University Medical Center Groningen (UMCG) with no aortic disease. Noncontrast CT scans were segmented with a 130 Hounsfield units (HU) threshold, and a patient-specific threshold was used for contrast-enhanced CTs. The LACS was calculated and compared from both segmentations. Secondly, the interobserver variability and the influence of slice thickness (0.75 mm vs. 2.0 mm) was determined. RESULTS: There was a high correlation between the LACS from contrast-enhanced CT scans and the LACS of noncontrast CTs ( R 2 = 0.98). A correction factor of 1.9 was established to convert the LACS derived from contrast-enhanced CT to noncontrast CT scans. LACS interobserver agreement on contrast-enhanced CT was excellent (1.0, 95% confidence interval = 1.0-1.0). The 0.75 mm CT threshold was 541 (459-625) HU compared with 500 (419-568) HU on 2 mm CTs ( p = 0.15). LACS calculated with both thresholds was not significantly different ( p = 0.63). CONCLUSION: The LACS seems to be a robust method for scoring calcium load on contrast-enhanced CT scans in arterial segments with various lengths.</p
Proceso para producir percarbonato de sodio a escala piloto
The idea of producing a sodium-percarbonate–based bleaching agent, well known in other countries, emerged from the minimum use of this product found in the Colombian chemical industry due to high cost and importing difficulties. In this sense, a current demand of the product is assessed, as well as the proper conditions to obtain it in the laboratory, the suspected scaling and the economic feasibility. The market survey resulted in a great variety of both the demand and prices of different bleaching agents. Competitor’s products were assessed finding sodium hypochlorite as the most commonly used bleaching agent, 23%, followed by hydrogen peroxide, 15%. The experimental design allows us to establish the connections of the reagent-mixture components to get a maximum yield of 52.0% regarding this stoichiometry connection. Finally, the feasibility of the project is concluded through the financial analysis.El proyecto de producir un agente blanqueador con base en percarbonato de sodio, bien conocido en otros países, surge a partir de su aplicación limitada en las industrias colombianas y debido a su alto costo y difi cultades para su importación.

Association of iliofemoral calcium score and major vascular complications within the first year after lower limb endovascular revascularization
BACKGROUND: The accumulation of calcium load in peripheral lower extremity arteries has been associated with increased severity of peripheral arterial disease (PAD) and mortality. While calcium scores are commonly calculated from non-contrast computed tomography (CT) scans, patients with PAD often undergo contrast-enhanced CT scans. This study aims to explore the association between a length-adjusted calcium score (LACS) of the iliofemoral arteries, determined through pre-intervention contrast-enhanced CT, and major adverse events in patients with chronic limb-threatening ischemia (CLTI).METHODS: A cohort of CLTI patients subjected to endovascular revascularization between 2005 and 2017 at a tertiary referral center were categorized into two groups. The complication group experienced one of the composite outcomes (reintervention, above-the-ankle amputation, and/or all-cause mortality within one year of the primary endovascular procedure), while control patients did not encounter this composite endpoint. Patients from the complication group were matched one-to-one with controls based on sex and Fontaine classification. LACS was calculated (Ca volume[mm3]/length[cm]) at three arterial segments; 1. the common iliac artery (CIA), 2. the external iliac artery and common femoral artery (EIA+CFA), and 3. the superficial femoral artery plus the popliteal artery (SFA+PA). Binary logistic regression analysis was conducted to investigate the association between LACS in the different arterial segments and the occurrence of the composite binary outcome (complication and control) and LACS of the different segments, adjusting influences of age, sex, BMI >25, Fontaine classification, diabetes mellitus type 1 & 2, chronic kidney disease stage, and hemodialysis treatment.RESULTS: Sixty-four CLTI patients were included in this study (complication group [n=32], and control group [n=32]). A significant difference (higher LACS was found for the complication group in the CIA, the SFA+PA, as well as the total trajectory. CLTI patients with high LACS in the SFA+PA or the total trajectory were more likely to suffer adverse events (SFA+PA: OR: 1.010, 95% CI: 1.000-1.020, p=0.04; Total LACS: OR: 1.008, 95% CI: 1.000-1.017, p=0.05).CONCLUSIONS: Patients with a high calcium load in the ilio-femoral arteries are at increased risk of major adverse events during one year after endovascular revascularization. The calcium score, derived from contrast-enhanced CT scans, holds potential utility in decision making for CLTI patients.</p
