Background: To date, there is a lack of published information on the utilization of the Deliberative dialogue methodology and the right to a dignified death in minors under 18 years of age in Colombia and Latin America.

Objective: To examine the issue of children and adolescents' entitlement to a dignified death, including the criteria for exclusion, and to formulate a comprehensive plan for pediatric palliative care. A public policy document will be created with the aim of supporting the implementation of Resolution 825/2018.

Methods: Participatory Action Research utilizing a Deliberative dialogue methods that has been adapted based on feminist epistemological principles.

Results: The outcome of the exercise was the production of a document containing Public Policy recommendations regarding euthanasia in minors and its submission to the Ministry of Health and Social Protection of Colombia a few days prior to the release of the Resolution regulating the right to a dignified death for this population. Additionally, the conclusions of this event enabled the creation of a guide for the implementation of (Cabildos Ciudadanos) Citizen Council, in which girls, boys, and adolescents are included, trans-disciplinarity is encouraged, and feminist epistemological foundations are explored.

Conclusions: The deliberative dialogue method may serve as a cost-efficient alternative to replace or complement participatory approaches utilized in the development of public health guidelines and policies.

Case description: A 22-year-old female patient received the first dose of Pfizer-BioNTech vaccine (RNAm) against COVID-19; 6 days later, she presented abdominal pain located in the right hypochondrium and epigastrium, associated with emetic episodes. Re-consultation 21 days later due to the same symptoms; three days after the second dose of the vaccine was administered.

Clinical findings: Pain on palpation in the right hypochondrium. Laboratories reported hepatocellular lesion and cholestasis, with negative amylase, hepatotropic virus and autoimmune hepatitis tests. Liver and biliary tract ultrasound and cholangioresonance were normal.

Treatment and results: Hyoscine and intravenous fluids as support therapy. She presented improvement in abdominal pain and progressive decrease of transaminases and bilirubin levels until normalization, and was discharged on the fifth day of hospitalization. A drug-associated hepatotoxicity (DILI) diagnosis was considered probable, in this case, secondary to vaccination against COVID-19.

Clinical relevance: The current SARS CoV-2 pandemic has spurred the development of new vaccines, the safety of which remains a concern. There is a likely causal relationship between vaccination and liver involvement in this clinical case, rather than simply a sporadic occurrence.

Background: Tuberculin skin test (TST) has played an essential in the diagnosis of latent tuberculosis infection (LTBI) for nearly a century.

Objective: This study aimed to investigate the general characteristics of patients tested with TST in a tertiary hospital within two years.

Methods: All patients who were evaluated to screen for tuberculosis and received a TST were included. The Mantoux method was used for TST administration.

Results: A total of 661 patients, 345 (52.2%) men and 316 (47.8%) women, with a mean age of 43.0 ±15.9 years, were included in the study. Accordingly, TST was performed prior to anti-TNF biological agent therapy for 50% (331) of the participants, for LTBI screening before solid organ and/or hematological stem cell transplantation for 20.4% (135), for screening following contact with tuberculosis for 25.1% (166), for screening of healthcare professionals for 1.1% (7), and medical report for 3.3% (22). 2.7% of the patients who took TST were diagnosed with active tuberculosis (14 with pulmonary tuberculosis and 4 with extrapulmonary tuberculosis). QuantiFERON-TB Gold (QFT) test was performed in 332 (50.2%) patients with anergic TST results. According to TST and QFT test results, 28.3% (187) of the patients were started on tuberculosis prophylaxis.

Conclusion: While TST is most performed for LTBI screening prior to biological agent therapy, almost one-fourth of patients taking TST require tuberculosis prophylaxis. On the other hand, about half of the patients require an additional QFT test.

Background: Patients undergoing cardiac surgery can experience functional impairment.

Objective: Assess the influence of Perme Score on the intensive care unit (ICU) length of stay in patients after cardiac surgery. As a secondary objective, investigate if preoperative variables can predict the patient's mobility status after surgery.

Methods: A prospective observational study was conducted in ICU in a university hospital. The mobility status (Perme Score) was collected from the first postoperative day until ICU discharge. The preoperative assessment of respiratory muscle strength, pulmonary function, and handgrip strength were collected.

Results: A total of 44 patients, mean age of 62.3 years, 28 men were included in the study. A high Perme Score on the second postoperative day among patients who underwent Coronary artery bypass grafting and the third postoperative day on three types of intervention (Coronary artery bypass grafting, valve replacement, or both simultaneously) was associated with shorter ICU length of stay). The preoperative pulmonary function was one of the main independent predictors of mobility status on the first three days of ICU stay, in addition to left ventricular ejection fraction and cardiopulmonary bypass time on the first day, age, and left ventricular ejection fraction on the second day and maximum expiratory pressure on third day.

Conclusion: An increase in mobility status (Perme Score), mainly on the third postoperative day, reduced the ICU stay, mainly influenced by preoperative pulmonary function.

Case description: Three cases of patients diagnosed with Hemi-uterus with non-communicating functional rudimentary cavity are reported.

Clinical findings: Adolescent patients with the presence of disabling pelvic pain during menstrual periods, in addition to depressive states and functional disability secondary to pain.

Treatment and outcome: Reconstruction of Hemi-uterus with non-communicating functional rudimentary cavity using a microsurgical technique, without the need for non-communicating horn resection. The patients were assessed at the 1st, third, and sixth months, showing a marked improvement in their dysmenorrhea. In addition, there was an improvement in the depressive state; there was no change in the volume of her menstrual bleeding, and one of these patients achieved pregnancy with normal prenatal control and cesarean delivery, obtaining a full-term newborn without complications.

Clinical relevance: Description of a novel microsurgical technique for the management of the hemi-uterus with a non-communicating functional rudimentary cavity, which could benefit not only the reduction of associated symptoms but could also become an alternative to improve fertility in these patients.

Introduction: Triphasic waves (TW) constitute an electroencephalographic pattern associated with certain kinds of encephalopathy. Brain atrophy may be a predisposing factor linked with TW.

Objective: To compare the degree of brain atrophy and white matter disease between patients with acute encephalopathy with and without TW.

Methods: A retrospective observational study including adult patients with encephalopathy, with and without TW, hospitalized between 2016 and 2017. The degree of brain atrophy and white matter lesion were defined using the Global Cortical Atrophy and Age Related White Matter Changes (ARWMC) scales, respectively. Scores were compared between groups. Mortality rates were registered.

Results: Sixteen patients with TW were identified matched by age and sex with 30 patients without TW. The mean age was 80 years in the TW group. Women represented 87.5%. Multifactorial encephalopathy was the most frequent diagnosis followed by metabolic encephalopathy. Patients with TW had more brain atrophy (10.43 vs 6.9, p= 0.03). Mean ARWMC was 9.43±6.5 and 8.5 ±7.89 in patients with and without TW respectively (p= 0.5). Mortality rate was higher in the TW group (31.25 vs 6.66% p= 0.02).

Conclusions: Patients with acute encephalopathy and TW had higher degree of cerebral atrophy. It is possible that this structural alteration predisposes to the appearance of TW. There was no significant difference in white matter lesion degree. The mortality of the TW group was high, so future studies are necessary to determine their prognostic value.

Objective: To identify pathogenic variants in an Afro-Colombian Raizal family with risk factors for glaucoma.

Methods: In the present study, whole exome sequencing was performed on seven members of a Raizal family from the archipelago of San Andrés, Providencia, and Santa Catalina, in the Caribbean region of Colombia. Four of them had been diagnosed with glaucoma. In addition, two healthy volunteers from the island were included.

Results: Of the 198 single nucleotide variants associated with glaucoma, previously reported by the DisGeNET database, four were identified in members of the Raizal family: rs11938093, rs7336216, rs3817672, and rs983034. Furthermore, single nucleotide variant rs983034 was identified in the Wnt ligand secretion mediator gene in all members of the family but not in healthy volunteers. Notably, WLS dysfunctions have been linked to pathology in the trabecular meshwork of the eye. Trabecular meshwork is an important regulator of the outflow of aqueous humor that maintains intraocular pressure (intraocular pressure) at normal levels. Damage to trabecular meshwork is associated with ocular hypertension, which leads to glaucoma progression. In relation to the other single nucleotide variants that were identified, their presence was confirmed in some members of the Raizal family. However, it is still unclear the pathophysiological cause that associates these single nucleotide variants with glaucoma.

Conclusions: It was possible to identify four non-synonymous single nucleotide variants that predict significant damage to the structure and function of genes associated with glaucoma pathology in an Afro-Colombian.

Background: Fat Mass and Obesity-related (FTO) has been one of the genes consistently related to common obesity. Single nucleotide polymorphisms (SNPs) in FTO have been linked with the IRX3 gene.

Aim: This study was designed by testing the hypothesis that: i) common SNPs in FTO and IRX3 are associated with obesity and related disorders; ii) there is significant linkage disequilibrium between both genes.

Methods: A cross-sectional study was carried out on the Colombian Caribbean Coast. Anthropometric and biochemical variables were measured, and obesity and metabolic disorders were diagnosed. Four SNPs were genotyped: 3 at FTO locus (rs17817449, rs8050136, rs9939609) and one at IRX3 locus (rs3751723). LD between these SNPs was estimated. A logistic regression model was applied to estimate associations.

Results: A total of 792 subjects were included. FTO and IRX3 were not in LD (D'≤ 0.03; R²≤ 0.03). TT genotype (rs9939609) was found to be associated with waist circumference (p= 0.04; adj-p= 0.01), and IRX3 SNP with Body Weight Excess (BWE) (OR= 1.06, adj-p= 0.03). One FTO-IRX3 haplotype was associated with BWE (G-A-A-T, rs17817449-rs8050136-rs9939609-rs3751723; OR= 0.67, p= 0.04). The statistical significance of these relations continued after admixture adjustment for a three-hybrid population (p= 0.03).

Conclusions: FTO was related to waist circumference, and IRX3 was associated with BWE in Latin American adults. This relation remained statistically significant after an adjustment for sex, age, and genetic ancestry was performed. Despite that these genes were not in LD, findings of a haplotype involving FTO-IRX3 suggest a gene-gene interaction associated with an increased risk of BWE.
