De novo transcriptome sequencing and annotation of the Antarctic polychaete Microspio moorei (Spionidae) with its characterization of the heat stress-related proteins (HSP, SOD & CAT).

We present a de novo transcriptome assembly for the non-model Antarctic polychaete worm Microspio moorei (Spionidae) collected during Antarctic field expedition in Fildes Bay, King George Island, Antarctic Peninsula, in 2017. Here, we report the first transcriptome reference array for Microspio spp. The gene sequences of the spionid worm were annotated from a wide range of functions (i.e., biological, and metabolic processes, catalytic processes, and catalytic activity). HSP70, HSP90 SOD and CAT families were compared to reported annelid transcriptomes and proteomes. The phylogenetic analysis using COI, 16S, and 18S markers effectively clusters the species within the family. However, it also casts uncertainty on the monophyletic nature of the Microspio genera, indicating the necessity for additional data and potentially requiring a reevaluation of its grouping. Within these protein families, 3D model software was used to create one representative of their protein structures. Structural predictions were compared with related reported annelids living at different temperatures and a human X-ray reference. We found structural differences (RMSE >1.8) between the human HSP proteins but no significant differences between the polychaete-predicted proteins (RMSE <1.2). These results encourage further research of heat stress-related proteins, the development of genetic markers for climate change-induced temperature stress, and the study of the underlying mechanisms of the heat response. Moreover, these results motivate the extension of these findings to congeneric species.

Racial differences in length of stay and readmission for asthma in the all of us research program.

BACKGROUND: This study addresses the limited research on racial disparities in asthma hospitalization outcomes, specifically length of stay (LOS) and readmission, across the U.S. METHODS: We analyzed in-patient and emergency department visits from the All of Us Research Program, identifying various risk factors (demographic, comorbid, temporal, and place-based) associated with asthma LOS and 30-day readmission using Bayesian mixed-effects models. RESULTS: Of 17,233 patients (48.0% White, 30.7% Black, 19.7% Hispanic/Latino, 1.3% Asian, and 0.3% Middle Eastern and North African) with 82,188 asthma visits, Black participants had 20% shorter LOS and 12% higher odds of readmission, compared to White participants in multivariate analyses. Public-insured patients had 14% longer LOS and 39% higher readmission odds than commercially insured patients. Weekend admissions resulted in a 12% shorter LOS but 10% higher readmission odds. Asthmatics with chronic diseases had a longer LOS (range: 6-39%) and higher readmission odds (range: 9-32%) except for those with allergic rhinitis, who had a 23% shorter LOS. CONCLUSIONS: A comprehensive understanding of the factors influencing asthma hospitalization, in conjunction with diverse datasets and clinical-community partnerships, can help physicians and policymakers to systematically address racial disparities, healthcare utilization and equitable outcomes in asthma care.

Multilevel Analysis of Racial and Ethnic Disparities in COVID-19 Hospitalization among Children with Allergies.

Rationale: Previous studies have identified risk factors for coronavirus disease (COVID-19) hospitalization in children. However, these studies have been limited in their ability to disentangle the contribution of racial disparities, allergic comorbidities, and environmental exposures to the development of severe COVID-19 in at-risk children with allergies. Objectives: To examine racial and ethnic disparities in COVID-19 hospitalization and their links to potentially underlying allergic comorbidities and individual and place-based factors in children with allergies. Methods: This is an electronic health record-based retrospective study of children in 2020. The outcome was COVID-19 hospitalization categorized as no hospital care for patients with asymptomatic/mild illness, short stay for patients admitted and discharged within 24 hours, and prolonged stay for patients requiring additional time to discharge (more than 24 h). Mixed-effects and mediation models were used to determine relationships among independent variables, mediators, and COVID-19 hospitalization. Results: Among the 5,258 children with COVID-19 positive test or diagnosis, 10% required a short stay, and 3.7% required a prolonged stay. Black and Hispanic children had higher odds of longer stays than non-Hispanic White children (both P < 0.001). Children with obesity and eosinophilic esophagitis diagnoses had higher odds of short and prolonged stay (all P < 0.05). Area-level deprivation was associated with short stay (adjusted odds ratio [AOR], 15.49; 95% confidence interval [CI], 5.16-45.47 for every 0.1-unit increase) and prolonged stay (AOR, 11.82; 95% CI, 2.25-62.01 for every 0.1-unit increase). Associations between race/ethnicity and COVID-19 hospitalization were primarily mediated by insurance and area-level deprivation, altogether accounting for 99% of the variation in COVID-19 hospitalization. Conclusions: There were racial and ethnic differences in children with allergies and individual and place-based factors related to COVID-19 hospitalization. Differences were primarily mediated by insurance and area-level deprivation, altogether accounting for 99% of the variation in COVID-19 hospitalization. A better understanding of COVID-related morbidity in children and the link to place-based factors is key to developing prevention strategies capable of equitably improving outcomes.

Effectiveness of a provider and patient-focused intervention to improve hypertension management and control in the primary health care setting in Cuba: a controlled before-after study.

BACKGROUND: Implementation research to improve hypertension control is scarce in Latin America. We assessed the effectiveness of an intervention aimed at primary care practitioners and hypertensive patients in a setting that provides integrated care through an accessible network of family practices. METHODS: We conducted in Cardenas and Santiago, Cuba, a controlled before-after study in 122 family practices, which are staffed with a doctor and a nurse. The intervention comprised a control arm (usual care), an arm with a component targeting providers (hypertension management workshops), and an arm with, on top of the latter, a component targeting patients (hypertension schools). To evaluate the effect, we undertook a baseline survey before the intervention and an endline survey sixteen months after its start. In each survey, we randomly included 1400 hypertensive patients. Controlled hypertension, defined as a mean systolic and diastolic blood pressure below 140 and 90 mmHg, respectively, was the primary endpoint assessed. We performed linear and logistic regression with a Generalized Estimating Equations approach to determine if the proportion of patients with controlled hypertension changed following the intervention. RESULTS: Seventy-three doctors, including substitutes, and 54 nurses from the 61 intervention family practices attended the provider workshops, and 3308 patients -51.6% of the eligible ones- participated in the hypertension schools. Adherence to anti-hypertensive medication improved from 42% at baseline to 63% at the endline in the intervention arms. Under the provider intervention, the proportion of patients with controlled hypertension increased by 18.9%, from 48.7% at baseline to 67.6% at endline. However, adding the component that targeted hypertensive patients did not augment the effect. Compared to patients in the control arm, the adjusted OR of having controlled hypertension was 2.36 (95% CI, 1.73-3.22) in the provider and 2.00 (95% CI, 1.68-2.37) in the provider plus patient intervention arm. CONCLUSIONS: The intervention's patient component remains to be fine-tuned. Still, we demonstrate that it is feasible to substantially improve hypertension outcomes by intervention at the primary care level, despite an already relatively high control rate.

HyperCKemia-MB due to macroCK type 1: Case report

HyperCKemia is a rare condition characterized by a persistent increase in serum creatine kinase (CK) levels or some isoenzymes. Usually, there are no clinical, electromyography or histological manifestations, which involves a challenge at the time of diagnosis. The patient in question showed no characteristic signs or symptoms, apart from fatigue and post-exercise myalgia. Assessment was performed by rheumatology and endocrinology, determination of total CK and MB fraction in blood, and electromyography and protein electrophoresis were requested as part of the approach. This case report is considered as novel, interesting, and useful for clinical practice as few similar ones were found in the scientific literature. The difficult etiological diagnosis of this entity, and the algorithm used to arrive at it, are all presented. It is concluded that in those patients with hyperCKemia of unknown etiology, this diagnosis should be kept in mind, and be confirmed by performing a CK electrophoresis.

La hiperCKemia es una condición poco frecuente caracterizada por un aumento persistente de los niveles de creatina quinasa (CK) sérica o de algunas isoenzimas, sin que suelan presentarse manifestaciones clínicas, electromiográficas o histológicas, lo cual implica un desafío a la hora del diagnóstico. El paciente cuyo caso se presenta aquí no mostró signos o síntomas característicos, únicamente fatiga y mialgias posteriores al ejercicio. Se llevó a cabo valoración por reumatología y endocrinología, determinación de CK total y fracción MB en sangre; además, se solicitó electromiografía y electroforesis de proteínas como parte del abordaje. Consideramos que este reporte de caso es novedoso, interesante y de utilidad para la práctica clínica pues se encuentran pocos similares en la literatura científica; adicionalmente, se pone en evidencia el difícil diagnóstico etiológico de esta entidad, así como el algoritmo utilizado para llegar a ella. Se concluye que este diagnóstico debe tenerse en mente en aquellos pacientes con hiperCKemia de etiología desconocida, y para confirmarlo es necesario hacer una electroforesis de CK.

Understanding racial disparities in childhood asthma using individual- and neighborhood-level risk factors.

BACKGROUND: Racial disparities in childhood asthma outcomes result from a complex interplay of individual- and neighborhood-level factors. OBJECTIVES: We sought to examine racial disparities in asthma-related emergency department (ED) visits between African American (AA) and European American (EA) children. METHODS: This is a retrospective study of patients younger than 18 years who visited the ED at Cincinnati Children's for asthma from 2009 to 2018. The outcome was number of ED visits during a year. We assessed 11 social, economic, and environmental variables. Mediation and mixed-effects analyses were used to assess relationships between race, mediators, and number of ED visits. RESULTS: A total of 31,114 children (46.1% AA, 53.9% EA) had 186,779 asthma-related ED visits. AA children had more visits per year than EA children (2.23 vs 2.15; P < .001). Medicaid insurance was associated with a 7% increase in rate of ED visits compared with commercial insurance (1.07; 95% CI, 1.03-1.1). Neighborhood socioeconomic deprivation was associated with an increased rate of ED visits in AA but not in EA children. Area-level particulate matter with diameter less than 2.5 µm, pollen, and outdoor mold were associated with an increased rate of ED visits for both AA and EA children (all P < .001). Associations between race and number of ED visits were mediated by insurance, area-level deprivation, particulate matter with diameter less than 2.5 µm, and outdoor mold (all P < .001), altogether accounting for 55% of the effect of race on ED visits. Race was not associated with number of ED visits (P = .796) after accounting for mediators. CONCLUSIONS: Racial disparities in asthma-related ED visits are mediated by social, economic, and environmental factors, which may be amenable to interventions aimed at improving outcomes and eliminating inequities.

Protocol for a controlled before-after quasi-experimental study to evaluate the effectiveness of a multi-component intervention to reduce gaps in hypertension care and control in low-income communes of Medellin, Colombia.

INTRODUCTION: Research on public health interventions to improve hypertension care and control in low-income and middle-income countries remains scarce. This study aims to evaluate the effectiveness and assess the process and fidelity of implementation of a multi-component intervention to reduce the gaps in hypertension care and control at a population level in low-income communes of Medellin, Colombia. METHODS AND ANALYSIS: A multi-component intervention was designed based on international guidelines, cross-sectional population survey results and consultation with the community and institutional stakeholders. Three main intervention components integrate activities related to (1) health services redesign, (2) clinical staff training and (3) patient and community engagement. The effectiveness of the intervention will be evaluated in a controlled before-after quasi-experimental study, with two deprived communes of the city selected as intervention and control arms. We will conduct a baseline and an endline survey 2 years after the start of the intervention. The primary outcomes will be the gaps in hypertension diagnosis, treatment, follow-up and control. Effectiveness will be evaluated with the difference-in-difference measures. Generalised estimation equation models will be fitted considering the clustered nature of data and adjusting for potential confounding variables. The implementation process will be studied with mixed methods. Implementation fidelity will be documented to assess to which degree the intervention components were implemented as intended. ETHICS AND DISSEMINATION: The study protocol has been approved by the Ethics Research Committee of Metrosalud in Colombia (reference 1400/5.2), the Medical Ethics Committee of the Antwerp University Hospital (reference 18/40/424) and the Institutional Review Board of the Antwerp Institute of Tropical Medicine (reference 1294/19). We will share and discuss the study results with the community, institutional stakeholders and national health policymakers. We will publish them in national and international peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER: NCT05011838.

Lidocaine infusión, basics and clinical issues / Lidocaína endovenosa, fundamentos y usos clínicos

Abstract Optimum pain management, minimizing chronic complications and ensuring a good safety profile, is growing in importance day by day. Lidocaine infusion has an adequate safety profile and several desirable characteristics in the clinical setting. This review describes the characteristics of this drug, as well as its potential indications. Moreover, it describes the basic concepts around lidocaine use, mechanisms of action and clinical applications, as well as the use of infusions in acute pain and repercussions in chronic pain. A review of the literature in English and Spanish was conducted in several databases, with no publication date limit. Articles considered relevant, without including the grey literature, were selected independently. Lidocaine infusion is an option for acute postoperative pain control in major surgery and contributes to opioid sparing and reduced length of stay, with ample evidence in abdominal surgery, rendering it an option to recommend in various protocols. It has an acceptable safety profile in special populations and it is considered useful to diminish the incidence of persistent, chronic and neuropathic pain related to the surgical procedure.

Gaps in Hypertension Management in a Middle-Income Community of Quito-Ecuador: A Population-Based Study.

Optimal hypertension care and control at population level significantly reduces cardiovascular morbidity and mortality. The study objective was to measure the gaps in the diagnosis, care, and control of hypertension in residents of an urban community in Quito, Ecuador. A cross-sectional population-based study with a sample of 2160 persons was performed using a survey and direct blood pressure measurement. Logistical regression models were used for analyzing factors associated with the gaps, expressed as percentages. The prevalence of hypertension was 17.6% [CI 95% 17.3-17.9%]. The diagnosis gap was 6.1% [CI 95% 5.9-6.2%] among the entire population and 34.5% [CI 95% 33.7-35.3%] among persons with hypertension. No access gaps were detected; whereas the follow-up gap was 22.7% [CI 95% 21.8-23.6%] and control gap reached 43.5% [CI 95% 42.6-44.2%]. Results indicated that being male, older than 64 years, an employee, without health insurance, and not perceiving a need for healthcare, increased the risk of experiencing these gaps. Data showed appropriate access to health services and high coverage in the diagnosis was due to the application of a community and family healthcare model. Notwithstanding, we found significant gaps in the follow-up and control of hypertensive patients, especially among older males, which should warrant the attention of the Ministry of Health.

Prevalencia de diabéticos controlados con hemoglobina glicosilada en dos áreas de salud. Cárdenas, 2019 / Prevalence of diabetics controlled by glycosylated hemoglobin in two health areas. Cardenas, 2019

RESUMEN Introducción: la diabetes mellitus es un trastorno metabólico caracterizado por hiperglucemia crónica con alteraciones en carbohidratos, grasas y proteínas. Debido al aumento de la morbimortalidad por diabetes, esta constituye un problema de salud en el mundo, en Cuba y en el contexto matancero. Objetivo: determinar la prevalencia de diabéticos controlados con la hemoglobina glicosilada (HbA1c), los factores asociados, y las barreras para una intervención posterior. Materiales y métodos: estudio epidemiológico, transversal, analítico a una cohorte de 601 diabéticos tipo 2 mayores de 18 años, en dos policlínicos, estudiados anteriormente. Se encuestaron y procesaron en el programa Epi-Info 7. Se obtuvieron frecuencias y proporciones de variables, prevalencia de diabéticos controlados con la hemoglobina HbA1c, los factores asociados, las comorbilidades con el OR, y las diferencias de variables entre los dos policlínicos, con el Chi2 y p < 0,05 %. Resultados: la prevalencia de diabéticos controlados fue de un 69,3 %. Las variables demográficas, comorbilidades y factores del estilo de vida no tuvieron diferencias estadísticamente significativas. Todas las variables (presencia y ausencia del factor) presentaron un control por encima del 64 %. El peso saludable, sobrepeso, enfermedades del corazón y respiratorias crónicas, ingestión de bebidas azucaradas y alimentación inadecuada, presentaron diferencias estadísticamente significativas entre los dos policlínicos. Conclusiones: No existieron diferencias entre las variables de diabéticos controlados y no controlados. Se identificaron las barreras para mejorar el control de los pacientes para una postintervención y mejorar su calidad de vida, pues un 30 % de los diabéticos no controlados presentaron algunos de los factores de riesgo estudiados (AU).

ABSTRACT Introduction: diabetes Mellitus is a metabolic disorder characterized by chronic hyperglycemia with alterations in carbohydrates, fats and proteins. Due to the increase of the morbidity and mortality rates, this is a health problem in the world, in Cuba and the province of Matanzas. Objective: to determine the prevalence of diabetics controlled with glycosylated hemoglobin (HbA1c), associated factors, and barriers to further intervention. Materials and method: an epidemiological, cross-sectional, analytical study was carried out in a cohort of 601 previously studied, type 2 diabetics over 18 years of age, in two polyclinics. The patients were surveyed and data processed in the Epi-Info 7 program. Frequencies and proportions of variables, prevalence of diabetics controlled by hemoglobin HbA1c, associated factors, comorbidities with odds ratio, as well as differences of variables between the two polyclinics were calculated by using Chi2 and p value <0.05 %. Results: the prevalence of controlled diabetics was 69.3 %. There were no statistically significant differences between demographic variables, co-morbidities and associated life style risk factors. All variables (presence and absence of the factor) showed control above 64 %. Healthy weight, overweight, heart and chronic respiratory diseases, sweet beverages intake and inadequate diet revealed statistically significant differences between the two polyclinics. Conclusions: there were no differences between the variables controlled and non-controlled diabetics. Barriers to improve patients control were identified for the sake of performing a subsequent intervention and improving their life quality, because 30 % of uncontrolled diabetic patients had some of the studied risk factors (AU).

Associated health and social determinants of mobile populations across HIV epidemic gradients in Southern Africa.

BACKGROUND: Growing travel connectivity and economic development have dramatically increased the magnitude of human mobility in Africa. In public health, vulnerable population groups such as mobile individuals are at an elevated risk of sexually transmitted diseases, including HIV. METHODS: The population-based Demographic Health Survey data of five Southern African countries with different HIV epidemic intensities (Angola, Malawi, South Africa, Zambia, and Zimbabwe) were used to investigate the association between HIV serostatus and population mobility adjusting for socio-demographic, sexual behavior and spatial covariates. RESULTS: Mobility was associated with HIV seropositive status only in Zimbabwe (adjusted odds ratio [AOR] = 1.37 [95% confidence interval [CI]: 1.01-1.67]). These associations were not significant in Angola, Malawi, South Africa, and Zambia. Females had higher odds of mobility than males in Zimbabwe (AOR = 1.37, CI: 1.10-1.69). The odds of mobility decreased with age in all five countries. CONCLUSIONS: Our findings highlight the heterogeneity of the social and health determinants of mobile populations in several countries with different HIV epidemic intensities. Effective interventions using precise geographic focus combined with detailed attribute characterization of mobile populations can enhance their impact especially in areas with high density of mobile individuals and high HIV prevalence.

The epidemiological landscape of anemia in women of reproductive age in sub-Saharan Africa.

The role of geographical disparities of health-related risk factors with anemia are poorly documented for women of reproductive age in sub-Saharan Africa (SSA). We aimed to determine the contribution of potential factors and to identify areas at higher risk of anemia for women in reproductive age in SSA. Our study population comprised 27 nationally representative samples of women of reproductive age (15-49) who were enrolled in the Demographic and Health Surveys and conducted between 2010 and 2019 in SSA. Overall, we found a positive association between being anemic and the ecological exposure to malaria incidence [adjusted odds ratio (AOR) = 1.02, 95% confidence interval (CI) 1.02-1.02], and HIV prevalence (AOR = 1.01, CI 1.01-1.02). Women currently pregnant or under deworming medication for the last birth had 31% (AOR = 1.31, CI 1.24-1.39) and 5% (AOR = 1.05, CI 1.01-1.10) higher odds of having anemia, respectively. Similarly, women age 25-34 years old with low education, low income and living in urban settings had higher odds of having anemia. In addition, underweight women had 23% higher odds of suffering anemia (AOR = 1.23, CI 1.15-1.31). Females with low levels of education and wealth index were consistently associated with anemia across SSA. Spatial distribution shows increased risk of anemia in Central and Western Africa. Knowledge about the contribution of known major drivers and the spatial distribution of anemia risk can mitigate operational constraints and help to design geographically targeted intervention programs in SSA.

Gaps in hypertension care and control: a population-based study in low-income urban Medellin, Colombia.

OBJECTIVES: To assess hypertension prevalence and the extent and associated factors of hypertension diagnosis, follow-up, treatment and control gaps in low-income urban Medellin, Colombia. METHODS: We randomly sampled 1873 adults aged 35 or older. Unaware hypertensive individuals were defined as those without previous diagnosis whose average blood pressure was equal to or above 140/90 mmHg. For aware hypertensive patients, control was delimited as average blood pressure below 140/90 if under 59 years old or diabetic, and as less than 150/90 otherwise. We used logistic regression to identify care gap-associated factors. RESULTS: Hypertension prevalence was 43.5% (95% CI 41.2-45.7). We found 28.2% aware and 15.3% unaware hypertensive individuals, which corresponds to a 35.1% (95% CI 31.9-38.5) underdiagnosis. This gap was determined by age, sex, education and lifestyle factors. 14.4% (95% CI 11.6-17.6) of aware hypertensive patients presented a follow-up gap, 93.4% (95% CI 90.9-95.2) were prescribed antihypertensive drugs, but 38.9% (95% CI 34.7-43.3) were not compliant. The latter was strongly associated with follow-up. The hypertension control gap in aware hypertensive patients, 39.0% (95% CI: 34.9-43.2), was associated with being older, having diabetes, weakly adhering to pharmacological treatment and receiving poor non-pharmacological advice. Overall, 60.4% (95% CI 57.0-63.8) of aware and unaware hypertensive participants had either diagnosed but uncontrolled or undiagnosed hypertension. CONCLUSIONS: We found high hypertension prevalence coupled with, from an international perspective, encouraging awareness and control figures. Still, there remains ample room for improvement. Our findings can assist in designing integrated primary healthcare measures that further strengthen equitable and effective access to hypertension care and control.

Identification of Vulnerable Populations and Areas at Higher Risk of COVID-19-Related Mortality during the Early Stage of the Epidemic in the United States.

We characterized vulnerable populations located in areas at higher risk of COVID-19-related mortality and low critical healthcare capacity during the early stage of the epidemic in the United States. We analyze data obtained from a Johns Hopkins University COVID-19 database to assess the county-level spatial variation of COVID-19-related mortality risk during the early stage of the epidemic in relation to health determinants and health infrastructure. Overall, we identified highly populated and polluted areas, regional air hub areas, race minorities (non-white population), and Hispanic or Latino population with an increased risk of COVID-19-related death during the first phase of the epidemic. The 10 highest COVID-19 mortality risk areas in highly populated counties had on average a lower proportion of white population (48.0%) and higher proportions of black population (18.7%) and other races (33.3%) compared to the national averages of 83.0%, 9.1%, and 7.9%, respectively. The Hispanic and Latino population proportion was higher in these 10 counties (29.3%, compared to the national average of 9.3%). Counties with major air hubs had a 31% increase in mortality risk compared to counties with no airport connectivity. Sixty-eight percent of the counties with high COVID-19-related mortality risk also had lower critical care capacity than the national average. The disparity in health and environmental risk factors might have exacerbated the COVID-19-related mortality risk in vulnerable groups during the early stage of the epidemic.

Control glicémico perioperatorio / Perioperatory glycemic control

Diabetes is the most common endocrinopathy, in 2014, 8.6% of the population suffered from diabetes, and it was responsible for at least 3.7 million deaths per year. It is estimated that by that by 2050 more than 30% of the population will have this disease. In cardiovascular surgery, it is described that 5.2% of patients are undiagnosed diabetics and this rises to 10% -28% in non-cardiac surgeries. The adverse results are markedly high in those patients with poor glycemic control including an increase of more than 50% in mortality, as well as an increase in respiratory infections, surgical site infection, urinary infection, heart attack and acute kidney injury among others. During the preoperative period of patients with diabetes, it is important to review glycemic control and its current treatment, in addition to providing the patient instructions on how to adjust medications. Intraoperatively, any condition that leads to an uncontrolled increase in surgical stress must be controlled, since this in turn generates hyperglycemia. Knowledge of insulins, their pharmacology and schedules is essential to maintain blood glucose intraoperatively in normal ranges. Different practical algorithms are proposed for the correct and safe management of hyperglycemia in the perioperative period. All care should be continued in the postoperative period defining the continuity of the insulin therapies established and the postoperative care of the patient.

La diabetes es la endocrinopatía más común, en 2014, el 8,6% de la población padecía diabetes siendo responsable de 3,7 millones de muertes por año. Se estima que para el 2050 más del 30% de la población tendrá diabetes. En cirugía cardiovascular el 5,2% de los pacientes son diabéticos no diagnosticados, cifra que aumenta hasta 10%-28% en cirugías no cardíacas. Los resultados adversos son marcadamente elevados en aquellos pacientes con mal control incluyendo un aumento del 50% en la mortalidad, así mismo, incremento de infecciones respiratorias, infección del sitio quirúrgico, infección urinaria, infarto agudo de miocardio y lesión renal aguda, entre otros. Durante el preoperatorio de pacientes con diabetes, es importante revisar el control glucémico y su tratamiento, además de proporcionar al paciente instrucciones por escrito sobre cómo ajustarlo. En el intraoperatorio se debe controlar cualquier condición que lleve a un aumento del estrés quirúrgico pues este a su vez genera hiperglucemia. Es fundamental el conocimiento de las insulinas, su farmacología y esquemas para mantener glucemias en el intraoperatorio en rangos normales. Se proponen diferentes algoritmos prácticos para el correcto y seguro manejo de la hiperglucemia en el perioperatorio. La atención debe continuarse en el posoperatorio definiendo continuidad de terapias insulínicas instauradas y el adecuado cuidado del paciente.

Out-of-pocket expenditure for hypertension care: a population-based study in low-income urban Medellin, Colombia.

Background Hypertension requires life-long medical care, which may cause economic burden and even lead to catastrophic health expenditure. Objective To estimate the extent of out-of-pocket expenditure for hypertension care at a population level and its impact on households' budgets in a low-income urban setting in Colombia. Methods We conducted a cross-sectional survey in Santa Cruz, a commune in the city of Medellin. In 410 randomly selected households with a hypertensive adult, we estimated annual basic household expenditure and hypertension-attributable out-of-pocket expenditure. For socioeconomic stratification, we categorised households according to basic expenditure quintiles. Catastrophic hypertension-attributable expenditure was defined as out-of-pocket expenditure above 10% of total household expenditure. Results The average annual basic household expenditure was US dollars at purchasing power parity (USD-PPP) $12,255.59. The average annual hypertension-attributable out-of-pocket expenditure was USD-PPP $147.75 (95% CI 120.93-174.52). It was incurred by 73.9% (95% CI 69.4%-78.1%) of patients, and consisted mainly of direct non-medical expenses (76.7%), predominantly for dietary requirements prescribed as non-pharmacological treatment and for transport to attend health care consultations. Medical out-of-pocket expenditure (23.3%) was for the most part incurred for pharmacological treatment. Hypertension-attributable out-of-pocket expenditure represented on average 1.6% (95% CI 1.3%-1.9%) of the total annual basic household expenditure. Eight households (2.0%; 95% CI 1.0%-3.8%) had catastrophic health expenditure; six of them belonged to the two lowest expenditure quintiles. Payments related to dietary requirements and transport to consultations were critical determinants of their catastrophic expenditure. Conclusions Out-of-pocket expenditure for hypertension care is moderate on average, but frequent, and mainly made up of direct non-medical expenses. Catastrophic health expenditure is uncommon and affects primarily households in the bottom socioeconomic quintiles. Financial protection should be strengthened by covering the costs of chronic diseases-related dietary requirements and transport to health services in the most deprived households.

Spatiotemporal transmission dynamics of the COVID-19 pandemic and its impact on critical healthcare capacity.

The role of geospatial disparities in the dynamics of the COVID-19 pandemic is poorly understood. We developed a spatially-explicit mathematical model to simulate transmission dynamics of COVID-19 disease infection in relation with the uneven distribution of the healthcare capacity in Ohio, U.S. The results showed substantial spatial variation in the spread of the disease, with localized areas showing marked differences in disease attack rates. Higher COVID-19 attack rates experienced in some highly connected and urbanized areas (274 cases per 100,000 people) could substantially impact the critical health care response of these areas regardless of their potentially high healthcare capacity compared to more rural and less connected counterparts (85 cases per 100,000). Accounting for the spatially uneven disease diffusion linked to the geographical distribution of the critical care resources is essential in designing effective prevention and control programmes aimed at reducing the impact of COVID-19 pandemic.
