Background: Li-Fraumeni syndrome (LFS) is an autosomal dominant hereditary cancer syndrome caused by pathogenic variants in the gene TP53. This gene codes for the P53 protein, a crucial player in genomic stability, which functions as a tumor suppressor gene. Individuals with LFS frequently develop multiple primary tumors at a young age, such as soft tissue sarcomas, breast cancer, and brain tumors.

Background: Salmonellosis is a major cause of morbidity and mortality and one of the most frequent etiologies of diarrhea in the world. Mortality due to Salmonellosis in Latin America still poorly understood, and there is a lack of studies that evaluate resistance and clinical manifestations. The aims of this study were to characterize patients infected with Salmonella spp.

The co-occurrence of COVID-19 with endemic diseases is a public health concern that may affect patient prognosis and outcomes. The objective of this study was to describe the clinical characteristics of patients with dengue virus (DENV) and SARS-CoV-2 co-infections and compare their outcomes against those of COVID-19 patients without dengue. A cross-sectional study was conducted in patients with SARS-CoV-2 infection who attended a single center in Cali, Colombia, from March 2020 to March 2021.

Ewing’s sarcoma is a bone and soft tissue neoplasm, whose management is related to hematological toxicity. This aspect represents a medical and ethical challenge in Jehovah’s Witnesses patients, who, due to their religious beliefs, reject the blood component transfusion, with the risk of discontinuing chemotherapy or using suboptimal doses. We present the case of a 34-year-old Colombian woman, Jehovah’s Witness, diagnosed with Ewing’s sarcoma with clinical stage IIB (T1N0M0) in the left maxillary and mandibular regions, treated with chemotherapy, who presented a hemoglobin nadir of up to 4.

Background: Gastric adenocarcinoma (GA) has changed in recent decades. Cancer estimates are often calculated from population-based cancer registries, which lack valuable information to guide decision-making (clinical outcomes). We describe the trends in clinical practice for GA using a hospital-based cancer registry over a timespan of 15 years.

Background: Acute myeloid leukemia (AML) is a hematological neoplasm that is more frequent in elderly patients. The objective of this study was to evaluate elderly patients' survival with AML and acute myeloid leukemia myelodysplasia-related (AML-MR), treated with intensive and less-intensive chemotherapy and supportive care.

Methods: A retrospective cohort study was conducted in Fundacion Valle del Lili (Cali, Colombia), between 2013 and 2019.

Cancer is one of the most burdening global health challenges. Indigenous communities are at high risk for worse healthcare outcomes because of inequalities in the incidence, prevalence, and mortality of oncological diseases, that arise from socioeconomic, racial, cultural, religious beliefs, and ethnic factors. Their perception about themselves is closely related to what affects their territory, making them possess a profound rooted feeling with their surroundings, and intense spiritual believes.

Background: The disparities in access to pediatric palliative care and pain management in Latin America remains an unaddressed global health issue. Efforts to improve the development of Palliative Care (PC) provision have traditionally targeted services for adults, leaving the pediatric population unaddressed. Examples of such services are scarce and should be portrayed in scientific literature to inform decision-makers and service providers on models of care available to tackle the burden of Pediatric Palliative Care (PPC) in Low-and middle-income countries (LMIC).

Background: Vector-borne diseases are a public health problem in Colombia, where dengue virus infection is hyperendemic. The introduction of other arboviruses, such as chikungunya and Zika in the last three years, has aggravated the situation. Mobile health (mHealth) offers new strategies for strengthening health care and surveillance systems promoting the collection, delivery, and access of health information to professionals, researchers, and patients.

Dengue fever is the most prevalent arbovirus infection among humans, and tropical regions are hyperendemic for this infection. The number of solid organ transplant recipients is continuously increasing, and there are few data regarding the clinical course and outcomes of dengue infection among this population. We report on a retrospective case series of solid organ transplant recipients with dengue virus infection from 2001 to 2018 at Fundación Valle del Lili in Cali, Colombia.

Dengue virus can infect humans through vectorial and non-vectorial transmission. Classically, non-vectorial transmission has been related to vertical transmission and health care-associated infections, but recently transmission to solid organ and bone marrow recipients has been reported. We performed a scoping review of the available literature searching for evidence on screening for dengue in potential organ donors and the use of these infected organs.

and are the most common microorganisms found in the amniotic fluid of patients at risk for preterm delivery. However, culture techniques for genital mycoplasms require special conditions, are barely considered as part of the evaluation of suspected intra-amniotic infection (IAI) and the results are available within 2 and 7 days. The objectives of this study are to validate the use of two commercially available kits (Mycoplasma IES y MYCOFAST RevolutioN) for the identification of spp.
