Introduction: Coronavirus Disease 2019 (COVID-19) is a severe respiratory illness caused by the RNA virus SARS-CoV-2. Globally, there have been over 759.4 million cases and 6.

The Autosomal Short Tandem Repeat Polymorphisms Are Potentially Associated with Cardiovascular Disease Predisposition in the Latin American Population: A Mini Review.

According to the World Health Organization, cardiovascular diseases (CVDs) are the leading cause of death worldwide across nearly all ethnic groups. Inherited cardiac conditions comprise a wide spectrum of diseases that affect the heart, including abnormal structural features and functional impairments. In Latin America, CVDs are the leading cause of death within the region.

Silk wastes and autoclaved degumming as an alternative for a sustainable silk process.

Silk degumming is considered the first point in the preparation of silk-based materials since this process could modify the silk fiber and the properties of its related products. This study evaluated the differences in morphology, secondary structure, amino acid content, thermal stability, and mechanical properties of two types of raw materials, defective cocoons (DC) and silk fibrous waste (SW), degummed by chemical (C) and autoclaving (A) methods. Subsequently, silk fibroin films were prepared by dissolving each type of degummed fibers, and thermal and structural films properties were determined.

Tactile misfit detection ability at the implant-abutment interface of internal connection dental implants: an in-vitro study.

Objective: The aim of this study was to investigate the tactile assessment ability at the implant impression-taking stage.

Methods: Thirty clinicians (18 novices, 12 experts) were included for a tactile fit assessment by using a used/new probe (tip diameter 100 µm/20 µm). Six implant replicas and related impression copings of two internal connection implant systems were used, each with a perfect fit (0 µm) and defined vertical micro gaps of 8, 24, 55, 110 and 220 µm at the interface.

Delusions and Hallucinations Are Associated With Greater Severity of Delirium.

Background: The 3 core domains of delirium (cognitive, higher level thinking, circadian) do not include the less common noncore psychotic symptoms. However, psychosis might inform about perturbations of neural circuitry, outcomes, or suggest tailored clinical management.

Objective: We assessed relationships between psychosis and other characteristics of delirium in patients without dementia or antipsychotics treatment.

Clinical, cytogenetic, and genomic analyses of an Ecuadorian subject with Klinefelter syndrome, recessive hemophilia A, and 1;19 chromosomal translocation: a case report.

Background: Hemophilia A is considered one of the most common severe hereditary disorders. It is an X-linked recessive disease caused by a deficiency or lack of function of the blood clotting factor VIII. Klinefelter syndrome is a genetic disorder that affects male individuals due to one or more extra X chromosomes, present in all cells or with mosaicism.

Understanding how socioeconomic inequalities drive inequalities in COVID-19 infections.

Across the world, the COVID-19 pandemic has disproportionately affected economically disadvantaged groups. This differential impact has numerous possible explanations, each with significantly different policy implications. We examine, for the first time in a low- or middle-income country, which mechanisms best explain the disproportionate impact of the virus on the poor.

Effect of Exposure to Socio-Political Violence and Abuse During Childhood on Executive Planning in Adult Life.

Objective: The exposure to unfavorable environments during childhood negatively affects the development of the executive planning abilities in adult life. In countries with sociopolitical conflicts, children are exposed to traumatic events as a result of child abuse and sociopolitical violence. The purpose of this study was to analyze the effect of the exposure to both forms of adverse childhood experiences on the executive planning abilities in adults from the general population.

First Report of SARS-CoV-2 Lineage B.1.1.7 (Alpha Variant) in Ecuador, January 2021.

On January 5 2021, Ecuadorian COVID-19 genomic surveillance program detected a suspicious case of the B.1.1.

COVID-19 spread, detection, and dynamics in Bogota, Colombia.

Latin America has been severely affected by the COVID-19 pandemic but estimations of rates of infections are very limited and lack the level of detail required to guide policy decisions. We implemented a COVID-19 sentinel surveillance study with 59,770 RT-PCR tests on mostly asymptomatic individuals and combine this data with administrative records on all detected cases to capture the spread and dynamics of the COVID-19 pandemic in Bogota from June 2020 to early March 2021. We describe various features of the pandemic that appear to be specific to a middle income countries.

Second GHEP-ISFG exercise for DVI: "DNA-led" victims' identification in a simulated air crash.

The Spanish and Portuguese-Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) has organized a second collaborative exercise on a simulated case of Disaster Victim Identification (DVI), with the participation of eighteen laboratories. The exercise focused on the analysis of a simulated plane crash case of medium-size resulting in 66 victims with varying degrees of fragmentation of the bodies (with commingled remains). As an additional difficulty, this second exercise included 21 related victims belonging to 6 families among the 66 missings to be identified.

Institutional and behaviour-change interventions to support COVID-19 public health measures: a review by the Lancet Commission Task Force on public health measures to suppress the pandemic.

The Lancet COVID-19 Commission Task Force for Public Health Measures to Suppress the Pandemic was launched to identify critical points for consideration by governments on public health interventions to control coronavirus disease 2019 (COVID-19). Drawing on our review of published studies of data analytics and modelling, evidence synthesis and contextualisation, and behavioural science evidence and theory on public health interventions from a range of sources, we outline evidence for a range of institutional measures and behaviour-change measures. We cite examples of measures adopted by a range of countries, but especially jurisdictions that have, thus far, achieved low numbers of COVID-19 deaths and limited community transmission of severe acute respiratory syndrome coronavirus 2.

Emergency surgery workforce and its inverse relationship with multidimensional poverty in Colombia.

Purpose: General surgeons, anesthesiologists, obstetricians and gynecologists (ob-gyns), and orthopedic surgeons are the vital disciplines to provide emergency surgery within a healthcare system. This paper aims to examine the relationship (if any) between multidimensional poverty (MDP) and GDP per-capita with the emergency surgery workforce density in Colombia.

Methods: We performed an ecological study, where the observation units were the 32 Colombian departments.

Frontoplasty Technique for the Mestizo Patient.

Ethnic groups can be differentiated through certain anatomical characteristics, including the morphological features of their skulls. Little information is available on the craniofacial measures of the Mestizo face. Over time, the upper third of the Mestizo face can develop a greater frontal concavity of the forehead, making the eyebrows drop and giving the face a more masculine appearance.

Fluctuating facial edema as a rare manifestation of cutaneous polyarteritis nodosa: Case report and review of the literature.

Polyarteritis nodosa (PAN) is a necrotizing vasculitis. The clinical manifestations are determined by the location of the compromised arteries. Cutaneous PAN can present as nodular lesions similar to erythema nodosum, palpable purpura, livedo reticularis, and ulceration.

Allelic Variation and Selection in Effector Genes of (Mont.) de Bary.

is a devastating plant pathogen in several crops such as potato (), tomato () and Andean fruits such as tree tomato (), lulo (), uchuva () and wild species in the genus sp. Despite intense research performed around the world, populations from Colombia, South America, are poorly understood. Of particular importance is knowledge about pathogen effector proteins, which are responsible for virulence.

The three-hybrid genetic composition of an Ecuadorian population using AIMs-InDels compared with autosomes, mitochondrial DNA and Y chromosome data.

The history of Ecuador was marked by the arrival of Europeans with Africans, resulting in the mixture of Native Americans with Africans and Europeans. The present study contributes to the knowledge of the Ecuadorian mestizo population by offering information about ancestry and ethnic heterogeneity. Forty-six AIM-InDels (Ancestry Informative Insertion/Deletion Markers) were used to obtain information on 240 Ecuadorian individuals from three regions (Amazonia, the Highlands, and the Coast).

Distinguishing characteristics of delirium in a skilled nursing facility in Spain: Influence of baseline cognitive status.

Objective: Mild cognitive impairment (MCI) and dementia (DEM) are prevalent in skilled nursing facilities (SNFs), confounding delirium detection. We report characteristics of delirium in an SNF to ascertain distinguishing features for delirium diagnosis, despite challenges of comorbidity with MCI and DEM.

Methods: Cross-sectional study of 200 consecutive patients from an SNF in Catalunya, Spain, assessed within the first 24 to 48 admission hours by independent experts with Spanish-Informant Questionnaire on Cognitive Decline in the Elderly (for MCI-DEM), Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) delirium criteria, and Delirium Rating Scale Revised-98 (DRS-R98) for delirium phenomenology.

Relationship between depressive symptomatology and cognitive performance in older people.

Objective: To analyze the relationship of depressive symptoms with differentiated components of cognitive function in older adults using the Neuronorma.Co protocol.

Methodology: We analyzed the cognitive performance of 144 adults, 58.

Higher pharmaceutical public expenditure after direct price control: improved access or induced demand? The Colombian case.

Background: High pharmaceutical expenditure is one of the main concerns for policymakers worldwide. In Colombia, a middle-income country, outpatient prescription represents over 10% of total health expenditure in the mandatory benefits package (POS), and close to 90% in the complementary government fund (No POS). In order to control expenditure, since 2011, the Ministry of Health introduced price caps on inpatient drugs reimbursements by active ingredient.

The geographic mosaic of Ecuadorian Y-chromosome ancestry.

Ecuadorians originated from a complex mixture of Native American indigenous people with Europeans and Africans. We analyzed Y-chromosome STRs (Y-STRs) in a sample of 415 Ecuadorians (145 using the AmpFlSTR Yfiler™ system [Life Technologies, USA] and 270 using the PowerPlexY23 system [Promega Corp., USA]; hereafter Yfiler and PPY23, respectively) representing three main ecological continental regions of the country, namely Amazon rainforest, Andes, and Pacific coast.
