RESUMO

OBJECTIVE: This research aimed to determine the stigma toward people with mental illness among mental health personnel and identify individual, professional, and contextual predictors. METHODS: A descriptive, cross-sectional, and correlational design was used. The sample consisted of 218 mental health personnel working in Outpatient Psychiatric Units belonging to hospitals and Community Mental Health Centers in Chile. Stigma was evaluated using a scale of humanized treatment, a scale of social distance, and a scale of attitudes in health personnel. In addition, sociodemographic and professional information was collected from mental health personnel and contextual information, particularly the type of outpatient mental health center and the technical-administrative unit that groups all the health centers in a territory. RESULTS: It was found that mental health personnel, in general terms, present low levels of stigma expressed in behaviors of comfort and support toward users, a desire for closeness and social interaction, and reduced stigmatizing beliefs and attitudes of infantilization toward individuals with MHPs. However, intimacy and trust were lower than expected.Only educational levels and health centers were related to stigma. CONCLUSIONS: The low levels of stigma may be due to the evolution of this phenomenon and the country's mental health policies.

RESUMO

Indigenous peoples around the world face significant health disparities relative to the dominant groups in their countries, yet the magnitude and patterns of health disparities vary across countries. We use data from the National Health Interview Survey and Mexican Family Life Survey to examine the health of Indigenous peoples in Mexico and American Indians and Alaska Natives in the USA and to evaluate how they fare relative to the majority populations in their countries (non-Indigenous Mexicans and non-Hispanic Whites, respectively). We assess disparities in self-rated health and activity limitations, with a focus on how Indigenous health disparities intersect with educational gradients in health. Regression analyses reveal three primary findings. First, Indigenous health disparities are larger in the USA than in Mexico. Second, differences in educational attainment account for most of the differences between Indigenous and non-Indigenous populations in Mexico, but less than half in the USA. Third, in both countries, health is moderated by educational attainment such that between-group disparities are largest at the highest levels of education. However, for Indigenous Mexicans there is a "cross-over" in which Indigenous Mexicans report better health at the lowest level of education. Overall, this study finds a weak relationship between education and Indigenous health, and raises the question about the validity of using traditional measures of SES in Indigenous contexts.

RESUMO

Over the last 20 years, the incidence of vertical HIV transmission has decreased from 25%-42% to less than 1%. Although there are no signs of infection, the health of HIV-exposed uninfected (HEU) infants is notoriously affected during the first months of life, with opportunistic infections being the most common disease. Some studies have reported effects on the vertical transfer of antibodies, but little is known about the subclass distribution of these antibodies. We proposed to evaluate the total IgG concentration and its subclasses in HIV+ mothers and HEU pairs and to determine which maternal factors condition their levels. In this study, plasma from 69 HEU newborns, their mothers, and 71 control pairs was quantified via immunoassays for each IgG isotype. Furthermore, we followed the antibody profile of HEUs throughout the first year of life. We showed that mothers present an antibody profile characterized by high concentrations of IgG1 and IgG3 but reduced IgG2, and HEU infants are born with an IgG subclass profile similar to that of their maternal pair. Interestingly, this passively transferred profile could remain influenced even during their own antibody production in HEU infants, depending on maternal conditions such as CD4+ T-cell counts and maternal antiretroviral treatment. Our findings indicate that HEU infants exhibit an altered IgG subclass profile influenced by maternal factors, potentially contributing to their increased susceptibility to infections.

RESUMO

The growing demand for gluten-free products requires the study of alternatives to produce nutritionally and technologically favorable foods. The aim was to evaluate the content and antioxidant capacity of gluten-free bread enriched with whole flour of purple maize (PM) and how starch and bioaccessibility of antioxidant compounds were modified during in vitro digestion. Gluten-free bread was prepared with the addition of 34%, 50%, and 70% PM, and white maize bread served as control. The content of total polyphenols, anthocyanins, and antioxidant capacity through FRAP and TEAC was measured. Specific volume, crumb texture, and starch digestibility were determined in the breads. Simultaneously, in vitro digestion and dialysis by membrane were performed to evaluate the bioaccessible and potentially bioavailable fraction. Bread with 34% PM had a similar specific volume and crumb texture to the control, but higher content of polyphenols (52.91 mg AG/100 g), anthocyanins (23.13 mg c3-GE/100 g), and antioxidant capacity (3.55 and 5.12 µmol tr/g for FRAP and TEAC, respectively). The PM breads had a higher antioxidant content and capacity and higher slowly digestible and resistant starch than the control. These parameters increased as the PM proportion rose. After digestion, anthocyanins were degraded, polyphenols and antioxidant capacity decreased, but they remained potentially bioavailable, although to a lesser extent. Bread with 34% shows acceptable technological parameters, lower starch digestibility, and contribution of bioactive compounds with antioxidant capacity. This indicates that purple maize flour represents a potential ingredient to produce gluten-free bread with an improved nutritional profile.

RESUMO

Recent studies have linked phenolic compounds to the inhibition of digestive enzymes. Propolis extract is consumed or applied as a traditional treatment for some diseases. More than 500 chemical compounds have been identified in propolis composition worldwide. This research aimed to determine Mexican propolis extracts' total phenolic content, total flavonoid content, antioxidant activity, and digestive enzyme inhibitory activity (ɑ-amylase and ɑ-glucosidase). In vitro assays measured the possible effect on bioactive compounds after digestion. Four samples of propolis from different regions of the state of Oaxaca (Mexico) were tested (Eloxochitlán (PE), Teotitlán (PT), San Pedro (PSP), and San Jerónimo (PSJ)). Ethanol extractions were performed using ultrasound. The extract with the highest phenolic content was PE with 15,362.4 ± 225 mg GAE/100 g. Regarding the flavonoid content, the highest amount was found in PT with 8084.6 ± 19 mg QE/100 g. ABTS•+ and DPPH• radicals were evaluated. The extract with the best inhibition concentration was PE with 33,307.1 ± 567 mg ET/100 g. After simulated digestion, phenolics, flavonoids, and antioxidant activity decreased by 96%. In contrast, antidiabetic activity, quantified as inhibition of ɑ-amylase and ɑ-glucosidase, showed a mean decrease in enzyme activity of approximately 50% after the intestinal phase. Therefore, it is concluded that propolis extracts could be a natural alternative for treating diabetes, and it would be necessary to develop a protective mechanism to incorporate them into foods.

RESUMO

Reef crests in the Caribbean have lost approximately 80% of the foundational habitat-forming coral Acropora palmata (Lamarck, 1816), with declines registered as early as the 1950s mainly from anthropogenic causes. We studied two reef crests in the northwestern region of Cuba over 17 years (2005 to 2021) to evaluate temporal changes in coral cover, dominated by A. palmata, and their potential drivers. The density of A. palmata generally showed a negative trend at both reefs, with the lowest density recorded in 2021 at 0.2 ± 0.05 col. m-2 at Playa Baracoa and 1.0 ± 0.1 col. m-2 at Rincon de Guanabo. The mean size of the colonies in the two reefs also decreased over time. In Playa Baracoa, the mean diameter of A. palmata colonies decreased from 2012 at 67 ± 5.9 cm to 2013 at 34 ± 2.2 cm, whereas in Rincon de Guanabo, a change in diameter was evident from 2015 at 44.3 ± 2.3 to 2021 at 21.6 ± 0.9 cm. Adult colonies (10 cm-50 cm diameter) predominated in most years on both reefs. The populations of A. palmata on both reefs were healthy, with an average of 70% colonies in good condition during the study period. However, A. palmata cover decreased by almost half by 2021, to 8.6% in Playa Baracoa and 16.8% in Rincon de Guanabo. By contrast, macroalgal cover increased two-fold to 87.1% in Playa Baracoa and four-fold to 77.2% in Rincon de Guanabo. The density of the sea urchin Diadema antillarum was higher in Playa Baracoa than in Rincon de Guanabo. The highest densities were 2.8 ± 0.2 ind. m-2 in Playa Baracoa in 2005 and 0.1 ± 0.03 ind. m-2 in Rincon de Guanabo in 2008. Although our results show an overall decline of A. palmata (density and percent cover) and an increase in macroalgae, these two reef crests are in better condition than most reefs in the Caribbean in terms of the density and health of A. palmata populations, and the density of D. antillarum at Playa Baracoa. Our results are important in establishing a management plan to ensure the condition of these reef crests does not degrade further.

RESUMO

BACKGROUND: In the literature on stigma, authors often use self-stigma or internalized stigma interchangeably to refer to this type of stigma. This results in a lack of conceptual clarity with negative repercussions for measurement and intervention. AIMS: To identify how internalized stigma and self-stigma are conceptualized in people diagnosed with a mental disorder and establish similarities and differences between both concepts. METHOD: A scoping review was conducted. Thirty-five studies that conceptualized internalized stigma or self-stigma were selected. RESULTS: It was identified that the concepts are defined from nine components, and there are more conceptualizations that have points in common than those that consider some component of their own. To gain conceptual clarity, the use of the term internalized stigma is recommended, being a process made up of stages: acceptance of stereotypes and prejudices by people with mental disorders and their subsequent internalization. The latter leads to negative consequences for those affected, which can be understood as the personal impact of this process, which has a crucial socio-cultural component. Lines of research are proposed to provide solidity to studies on this type of stigma. CONCLUSIONS: The term internalized stigma should be used when referring to the type of stigma that includes acceptance, internalization and personal impact for the subjects of the stigma. In contrast, self-stigma should be reserved to refer to stigma that is directed toward the 'self' and includes subtypes of stigma.

RESUMO

OBJECTIVES: The present study examined whether teen mothers' adaptive cultural characteristics (i.e., familism values, language competency pressures, and involvement in Mexican culture and U.S. mainstream culture) when children were 3 years old (i.e., Wave 4; W4) informed mothers' Spanish language use with their children when children were 4 years old (W5) and, in turn, children's subsequent Spanish receptive vocabulary when children were 5 years old (W6). METHOD: The present study included 204 Mexican-origin children (58% male) and their mothers who entered parenthood during adolescence (M = 16.24, SD = .99 at W1). RESULTS: Five mediational processes were significant, such that mothers' higher familism values (i.e., emphasizing family support and obligations), Spanish competency pressure (i.e., stress associated with Spanish language competency), and involvement in U.S. mainstream culture at W4 were associated with mothers' lower Spanish language use with children at W5 and, in turn, children's lower levels of Spanish receptive vocabulary at W6. Mothers' greater involvement in Mexican culture and English competency pressure (i.e., stress associated with English language competency) at W4 were associated with mothers' greater Spanish language use with children at W5 and, in turn, children's greater Spanish receptive vocabulary at W6. Additionally, mothers' greater involvement in U.S. mainstream culture at W4 was directly associated with children's lower Spanish language abilities at W6. CONCLUSIONS: Findings highlight the importance of the family context in Mexican-origin children's Spanish language skills over time. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

Background: The metabolic syndrome (MS) is associated with an increased production of nitrogen metabolites and elevated oxidative stress, which favors progression of nonalcoholic fatty liver disease (NAFLD). Subjects with the phenotype known as metabolically unhealthy obese (MUO) meet most of the MS cardiometabolic risk criteria and show a higher risk of advanced NAFLD severity, compared with the so-widely known metabolically healthy obese (MHO). Obese individuals with MS are more susceptible to abnormal lipid accumulation in different tissues, whereas oxidative stress and nitrogen metabolites are increased in MS and/or obesity. This study aimed to explore whether plasma- or liver tissue-determined biomarkers of nitrogen metabolism and oxidative stress relate to NAFLD severity and/or metabolic phenotype. Methods: This cross-sectional study included candidates for bariatric surgery with biopsy-proven NAFLD diagnosis and staging. For comparison, the study population was divided according to NAFLD damage (steatohepatitis F0-F1 vs. steatohepatitis F2-F4) and metabolic phenotype (MHO vs MUO, based on the MS criteria). Hepatic and plasma concentrations of nitrogen metabolites and oxidative stress biomarkers were determined by enzymatic kinetics assays, enzyme-linked immunosorbent assay, and Greiss reaction. Results: The study population (N = 45) was constituted by patients with obesity and higher prevalence of dyslipidemia, diabetes mellitus, and hypertension. According to plasma biomarkers, MUO phenotype was related to higher cardiometabolic risk; meanwhile, advanced NAFLD damage was related to higher glycated hemoglobin (HbA1c) and triglycerides. Elevated hepatic concentrations of ammonium, nitrites, arginine, and citrulline were found in MUO phenotype, but only higher plasma concentration of malondialdehyde was found as specifically related to advanced NAFLD damage. Conclusions: Circulating biomarkers of redox state were selectively related to advanced NAFLD damage, suggesting prognostic and therapeutic targets. Hepatic concentrations of nitrogen metabolism biomarkers may be more related to cardiometabolic risk.

Higher education is a fundamental right of every human being. From this premise, university becomes an intercultural space for deaf students that provides the opportunity for the exchange of experiences, customs, and learning that occur during their inclusion in education. It becomes a challenge for the deaf population, enabling their independence, autonomy, and equal opportunities. For this reason, speech therapists and special education teachers become professionals who must participate in the decision-making processes, eliminating barriers and creating facilitators. The objective of this study was to design guidelines for the involvement of speech therapists and special education teachers in the higher education of deaf individuals. The research methodology was qualitative and descriptive, involving semistructured interviews with male and female professionals from Colombia and Chile, aged 18 and above, with experience in higher education. The results indicate that the design of guidelines allows for interdisciplinary work by both speech therapists and special education teachers in the inclusion processes of deaf students in higher education, addressing their needs, mitigating barriers, and preventing academic failure and dropout. In conclusion, the importance of considering the participation of professionals is established, highlighting crucial elements such as knowledge, professionalism, sensitization, reflection, communication, context, support, and adjustments. These elements support the foundation of training and performance for understanding and recognizing their roles in inclusion teams. These elements form the fundamental basis for the construction of the guidelines.

RESUMO

The Festuca arundinacea Schreb. is one of the most used forage grasses due to its duration, productivity, great ecological breadth, and adaptability. Livestock has been criticized for its large production of greenhouse gases (GHG) due to forage. The advancement of science has led to an increase in the number of studies based on nanotechnologies; NPs supplementation in animal nutrition has found positive results in the fermentation of organic matter and the production of fatty acids and ruminal microorganisms. The objectives of this study were (1) to evaluate the in vitro digestibility of forage containing selenium (Se) nanoparticles (NPs), and to identify the specific behavior of the ruminal fermentation parameters of F. arundinacea Schreb. and (2) quantify the production of greenhouse gases (total gas and methane) (3) as well as the release of bioactive compounds (phenols, flavonoids, tannins, and selenium) after fermentation. Three treatments of SeNPs were established (0, 1.5, 3.0, and 4.5 ppm). The effects of foliar fertilization with SeNPs son digestion parameters were registered, such as the in vitro digestion of dry matter (IVDM); total gas production (Atotal gas) and methane production (ACH4); pH; incubation time(to); the substrate digestion rate (S); tSmax and the lag phase (L); as well as the production of volatile fatty acids (VFA), total phenols, total flavonoids, and tannins in ruminal fluid. The best results were obtained in the treatment with the foliar application of 4.5 ppm of SeNPs; IVDMD (60.46, 59.2, and 59.42%), lower total gas production (148.37, 135.22, and 141.93 mL g DM-1), and CH4 (53.42, 52.65, and 53.73 mL g DM-1), as well as a higher concentration of total VFA (31.01, 31.26, and 31.24 mmol L-1). The best results were obtained in the treatment with the foliar application of 4.5 ppm of SeNPs in the three different harvests; concerning IVDMD (60.46, 59.2, and 59.42%), lower total gas production (148.37, 135.22, and 141.93 mL g DM-1), and CH4 (53.42, 52.65, and 53.73 mL g DM-1), as well as a higher concentration of total VFA (31.01, 31.26, and 31.24 mmol L-1). The F. arundinacea Schreb. plants fertilized with 4.5 ppm released-in the ruminal fluid during in vitro fermentation-the following contents: total phenols (98.77, 99.31, and 99.08 mgEAG/100 mL), flavonoids (34.96, 35.44, and 34.96 mgQE/100 g DM), tannins (27.22, 27.35, and 27.99 mgEC/100g mL), and selenium (0.0811, 0.0814, and 0.0812 ppm).

RESUMO

BACKGROUND: Deep neck abscesses can cause life-threatening complications. They are diagnosed by physical examination, and contrasted tomography as the gold standard. There are no studies about the association of Moore's sign with infections of the retropharyngeal space. OBJECTIVE: To determine the usefulness of Moore's sign in the diagnosis of deep retropharyngeal abscess. METHOD: Observational, analytical, cross-sectional, study of patients with deep neck abscess, from May 1, 2019, to August 30, 2021, with report of Moore's sign. RESULTS: 87 patients were included, 49 (56.3%) males (p = 0.45). Of those who developed complications, 77.8% had a negative Moore's sign (p = 0.001). Of those admitted to the ICU, 72% had a negative Moore's sign (p = 0.001). The sensitivity of the absence of the sign with retropharyngeal involvement was 95.4%, and the specificity was 86.3%. By logistic regression, it was found that those with retropharyngeal involvement are 467 times more likely to present a negative sign (p < 0.05). CONCLUSIONS: The presence of abscess in the retropharynx is associated with complications and a worse prognosis. The evaluation of Moore's sign can be a useful tool to suspect compromise of this space.

ANTECEDENTES: Los abscesos profundos de cuello pueden ocasionar complicaciones letales. Se diagnostican por exploración física, y la tomografía contrastada es el método de referencia. No existen estudios de asociación del signo de Moore con infecciones del espacio retrofaríngeo. OBJETIVO: Determinar la utilidad del signo de Moore en el diagnóstico de absceso profundo en el espacio retrofaríngeo. MÉTODO: Estudio observacional, transversal y analítico, de pacientes con absceso profundo de cuello, del 1 de mayo de 2019 al 30 de agosto de 2021, con reporte de signo de Moore. RESULTADOS: Se incluyeron 87 pacientes, de los cuales 49 (56.3%) eran de sexo masculino (p = 0.45). De los que desarrollaron complicaciones, el 77.8%, tenían el signo de Moore negativo (p = 0.001). De los que ingresaron a la unidad de cuidados intensivos, el 72% tenían negativo el signo de Moore (p = 0.001). La sensibilidad de la ausencia del signo con afección del espacio retrofaríngeo fue del 95.4%, y la especificidad del 86.3%. Por regresión logística se encontró que aquellos con afección del espacio retrofaríngeo tienen 467 veces más posibilidades de presentar signo negativo (p < 0.05). CONCLUSIONES: La presencia de un absceso en el espacio retrofaríngeo se asocia a complicaciones y peor pronóstico. La evaluación del signo de Moore puede ser una herramienta útil para sospechar compromiso de ese espacio.

RESUMO

Festuca arundinacea Schreb. is a widely used type of forage due to its great ecological breadth and adaptability. An agricultural intervention that improves the selenium content in cultivated plants has been defined as bio-fortification, a complementary strategy to improve human and non-human animals' nutrition. The advancement of science has led to an increased number of studies based on nanotechnologies, such as the development of nanoparticles (NPs) and their application in crop plants. Studies show that NPs have different physicochemical properties compared to bulk materials. The objectives of this study were (1) to determine the behavior of F. arundinacea Schreb. plants cultivated with Se nanoparticles, (2) to identify the specific behavior of the agronomic and productive variables of the F. arundinacea Schreb. plants, and (3) to quantify the production and quality of the forage produced from the plant (the bioactive compounds' concentrations, antioxidant activity, and the concentration of selenium). Three different treatments of SeNPs were established (0, 1.5, 3.0, and 4.5 mg/mL). The effects of a foliar fertilization with SeNPs on the morphological parameters such as the root size, plant height, and biomass production were recorded, as well as the effects on the physicochemical parameters such as the crude protein (CP), lipids (L), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), carbohydrates (CH), the content of total phenols, total flavonoids, tannins, quantification of selenium and antioxidant activity 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and 2,2-diphenyl-1-picrylhydrazyl (DPPH). Significant differences (p < 0.05) were found between treatments in all the response variables. The best results were obtained with foliar application treatments with 3.0 and 4.5 mg/mL with respect to the root size (12.79 and 15.59 cm) and plant height (26.18 and 29.34 cm). The F. arundinacea Schreb. plants fertilized with 4.5 mg/L had selenium contents of 0.3215, 0.3191, and 0.3218 mg/Kg MS; total phenols of 249.56, 280.02, and 274 mg EAG/100 g DM; and total flavonoids of 63.56, 64.96, and 61.16 mg QE/100 g DM. The foliar biofortified treatment with a concentration of 4.5 mg/mL Se NPs had the highest antioxidant capacities (284.26, 278.35, and 289.96 mg/AAE/100 g).

RESUMO

In the present study, the effects of ultrasound (10, 20, and 30 min) on the bioactive compounds, antioxidant capacity, enzymatic inhibition, and in vitro digestion of six honey extracts from the Oaxaca state, Mexico, were analyzed. Significant differences were found in each honey extract with respect to the ultrasonic treatment applied (p < 0.05). In the honey extract P-A1 treated with 20 min of ultrasound, the phenols reached a maximum concentration of 29.91 ± 1.56 mg EQ/100 g, and the flavonoids of 1.92 ± 0.01 mg EQ/100 g; in addition, an inhibition of α-amylase of 37.14 ± 0.09% was noted. There were also differences in the phases of intestinal and gastric digestion, presenting a decrease in phenols (3.92 ± 0.042 mg EQ/100 g), flavonoids (0.61 ± 0.17 mg EAG/100 mg), antioxidant capacity (8.89 ± 0.56 mg EAG/100 mg), and amylase inhibition (9.59 ± 1.38%). The results obtained from this study indicate that, in some honeys, the processing method could increase the concentration of bioactive compounds, the antioxidant capacity, and the enzymatic inhibition; however, when subjected to in vitro digestion, the properties of honey are modified. The results obtained could aid in the development of these compounds for use in traditional medicine as a natural source of bioactive compounds.

RESUMO

BACKGROUND: Clinical Ethics Committees are deliberative groups whose main functions are to assess cases with ethical-clinical conflicts, to generate institutional protocols for preventive purposes, and to train health teams. AIM: To analyze the activity of a clinical ethics committee of a general hospital in the period 2007-2020. MATERIAL AND METHODS: A retrospective analysis of all session records, annual reports, case resolution and documents generated by the Clinical Ethics Committee of Carlos van Buren Hospital in Valparaíso, Chile, between 2007 and 2020, was carried out. RESULTS: On average, 12 cases are analyzed per year. Sixty percent correspond to requests from pediatric units and in 78% of these cases there was at least one neurological disease. In 62% of cases, the main ethical dilemma was adequacy of therapeutic effort, followed by dilemmas related to the exercise of autonomy in 18.2%. In education, two courses are identified aimed to doctors, residents, and other members of the health team. Regarding normative functions, several documents were generated at the request of the Hospital management or in different clinical situations. During COVID-19 pandemia, the active role of the committee was linked to the three main functions, namely evaluating cases, participating in morbidity and mortality meetings for preventive purposes, and issuing guidelines and recommendations for action. The active participation of Pediatric Neurology residents in the Committee, for educational and administrative purposes, stands out. CONCLUSIONS: The three main functions described for the ethics committees were exerted by this Committee during the evaluated period. The impact of our recommendations remain to be objectively evaluated.

RESUMO

Preterm neonates are at high risk of infectious and inflammatory diseases which require antibiotic treatment. Antibiotics influence neonatal gut microbiome development, and intestinal dysbiosis has been associated with delayed gastrointestinal transit. Neonates who take less time to pass meconium have a better tolerance to enteral feeding. We analyzed the effect of neonatal antibiotic treatment on the stool pattern and oral tolerance in 106 preterm infants < 33 weeks gestational age. Neonates were classified in 3 groups according to neonatal antibiotic (ABT) treatment days: no antibiotics, 3−7 d ABT, and ≥8 d ABT. Preterm infants from the ≥8 d ABT group took longer to pass meconium and to start green and yellow stools, took longer to reach 100 and 150 mL/kg/day, and reached reduced volumes in enteral feeds at day of life 14 and 28 than infants from no ABT and 3−7 d ABT groups. Multiple linear regression models showed that neonatal antibiotic treatment, birth weight, invasive mechanical ventilation, surfactant, enteral feeding start day, neonatal parenteral nutrition, and neonatal fasting days are associated with the stool pattern and oral tolerance in preterm infants.

RESUMO

INTRODUCTION: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic revealed a worldwide lack of effective molecular surveillance networks at local, state, and national levels, which are essential to identify, monitor, and limit viral community spread. SARS-CoV-2 variants of concern (VOCs) such as Alpha and Omicron, which show increased transmissibility and immune evasion, rapidly became dominant VOCs worldwide. Our objective was to develop an evidenced-based genomic surveillance algorithm, combining reverse transcription polymerase chain reaction (RT-PCR) and sequencing technologies to quickly identify highly contagious VOCs, before cases accumulate exponentially. METHODS: Deidentified data were obtained from 508,969 patients tested for coronavirus disease 2019 (COVID-19) with the TaqPath COVID-19 RT-PCR Combo Kit (ThermoFisher) in four CLIA-certified clinical laboratories in Puerto Rico (n = 86,639) and in three CLIA-certified clinical laboratories in the United States (n = 422,330). RESULTS: TaqPath data revealed a frequency of S Gene Target Failure (SGTF) > 47% for the last week of March 2021 in both, Puerto Rico and US laboratories. The monthly frequency of SGTF in Puerto Rico steadily increased exponentially from 4% in November 2020 to 47% in March 2021. The weekly SGTF rate in US samples was high (>8%) from late December to early January and then also increased exponentially through April (48%). The exponential increase in SGFT prevalence in Puerto Rico was concurrent with a sharp increase in VOCs among all SARS-CoV-2 sequences from Puerto Rico uploaded to Global Influenza Surveillance and Response System (GISAID) (n = 461). Alpha variant frequency increased from <1% in the last week of January 2021 to 51.5% of viral sequences from Puerto Rico collected in the last week of March 2021. CONCLUSIONS: According to the proposed evidence-based algorithm, approximately 50% of all SGTF patients should be managed with VOCs self-quarantine and contact tracing protocols, while WGS confirms their lineage in genomic surveillance laboratories. Our results suggest this workflow is useful for tracking VOCs with SGTF.
