Revisión integrativa sobre evidencia actual de la uretroplastia / Integrative review on current evidence for urethroplasty

La uretroplastía se ha convertido en el estándar de manejo de la estrechez uretral, dependiendo de la localización y etiología de esta. Los datos de los resultados a largo plazo varían dependiendo de la definición que se utilice como éxito (subjetiva u objetiva). El objetivo de esta revisión integrativa es mostrar la información disponible sobre los resultados funcionales de pacientes con estrechez uretral manejados quirúrgicamente. El estudio es una revisión integrativa que se realizó mediante una búsqueda de la literatura en PubMed. Incluimos artículos que describían resultados de pacientes sometidos a reconstrucción uretral con uretroplastia, solo hombres, en inglés o español, publicados entre 1999-2022. Incluimos 34 artículos, los cuales mostraron que, según el tipo de procedimiento realizado, las características de la estrechez uretral y las variables definidas como éxito y fracaso, los factores de riesgo asociados a la recurrencia posterior a la reconstrucción con uretroplastia en uretra fueron la presencia de comorbilidades, obesidad y etiología infecciosa. Concluimos entonces que la uretroplastia es un procedimiento que ha aumentado en los últimos años, con pocos estudios que nos comparan resultados dependiendo del tipo de procedimiento utilizado. Nuestra revisión encontró que hay mayor literatura sobre el uso de injertos de mucosa oral comparado con escición primaria y anastomosis (EPA), con unos resultados anatómicos y funcionales comparables entre ambos procedimientos. Los cuestionarios PROMS (Patient Reported Outcome Measures) son herramientas útiles para el seguimiento postoperatorio de estos pacientes.

Urethroplasty has become the standard for managing urethral stricture, depending on its location and etiology. Long-term outcome data varies depending on the definition of success used (subjective or objective). The objective of this integrative review is to show the available information on the functional results of patients with surgically managed urethral stricture. The study is an integrative review that was carried out through a literature search in PubMed, we included articles that described the results of patients undergoing urethral reconstruction with urethroplasty, only men, in English or Spanish, published between 1999-2022. The study included 34 articles, which showed that, depending on the type of procedure performed, the characteristics of the urethral stricture and the variables defined as success and failure, the risk factors associated with recurrence after reconstruction with urethroplasty in the urethra were the presence of comorbidities, obesity, and infectious etiology. In conclusion, urethroplasty is a procedure that has increased in recent years, with few studies that compare results depending on the type of procedure used. Our review found that there is more literature on the use of buccal mucosa graft (BMG) compared to excision and primary anastomotic urethroplasy (EPA), with comparable anatomical and functional results between both procedures.

Safety of intracameral application of moxifloxacin and dexamethasone (Vigadexa®) after phacoemulsification surgery.

BACKGROUND: Intracameral antibiotics, such as moxifloxacin and cefuroxime, are safe to corneal endothelial cells and effective prophylaxis of endophthalmitis after cataract surgery. Corneal endothelial cells decrease in density after cataract surgery. Any substance used in the anterior chamber may affect corneal endothelial cells and lead to a greater decrease in density. This study wants to determine the percentage of endothelial cell loss after cataract extraction by phacoemulsification with off-label intracameral injection of moxifloxacin and dexamethasone (Vigadexa®). METHODS: An observational retrospective study was performed. The clinical records of patients undergoing cataract surgery by phacoemulsification plus intracameral injection of Vigadexa® were analyzed. Endothelial cell loss (ECL) was calculated using preoperative and postoperative endothelial cell density. The relation of endothelial cell loss with cataract grade using LOCS III classification, total surgery time, total ultrasound time, total longitudinal power time, total torsional amplitude time, total aspiration time, estimated fluid usage, and cumulative dissipated energy (CDE) was studied using univariate linear regression analysis and logistic regression analysis. RESULTS: The median loss of corneal endothelial cells was 4.6%, interquartile range 0 to 10.4%. Nuclear color and CDE were associated with increased ECL. ECL>10% was associated with age and total ultrasound time in seconds. CONCLUSIONS: The endothelial cell loss after the intracameral use of Vigadexa® at the end of cataract surgery was similar to the reported in other studies of cataract surgery without the use of intracameral prophylaxis for postoperative endophthalmitis (POE). This study confirmed the association of CDE and nuclear opalescence grade with postoperative corneal endothelial cell loss.

Adherence to pharmacological treatment in non-communicable chronic diseases in the Colombian population: Systematic review and meta-analysis / Cumplimiento del tratamiento farmacológico en enfermedades crónicas no transmisibles en la población colombiana: revisión sistemática y metaanálisis.

Introduction. Non-communicable chronic diseases represent the leading cause of death worldwide, and their prevalence is increasing due to the epidemiological transition. Despite the advances in their management, control rates are deficient, attributed to multiple factors like adherence to pharmacological treatment, one of the most significant and least studied in the Colombian population. Objective. To calculate adherence to treatment in Colombian patients with arterial hypertension, cerebrovascular disease, diabetes mellitus, asthma, chronic obstructive pulmonary disease, and dyslipidemia between 2005 and 2022. Materials and methods. We performed a systematic literature review and a meta-analysis of studies identified through the Medline and LILACS databases to quantitatively synthesize treatment adherence percentage. Results. Fourteen studies met the inclusion criteria, and 5,658 patients were analyzed. The treatment adherence was 59%, with significant heterogeneity among the included studies (95% CI= 46- 71%; I2 = 98.8%, p< 0.001). Higher adherence rates were observed for diabetes mellitus (79%; 95% CI = 65- 90%) and dyslipidemia (70%; 95% CI = 66- 74%). Adherence to arterial hypertension treatment was 51% (95 %; CI = 31- 72%). Conclusions. This systematic review showed low adherence to recommendations regarding pharmacological management in non-communicable chronic diseases, which can have implications for long-term clinical outcomes and disease burden.

Introducción. Las enfermedades crónicas no transmisibles representan la principal causa de muerte en el mundo y su prevalencia va en aumento debido a la transición epidemiológica. A pesar de los avances en su manejo, las cifras de control son deficientes y esto se atribuye a múltiples factores, como el cumplimiento del tratamiento farmacológico, que es uno de los más representativos y menos estudiados en la población colombiana.Objetivo. Establecer la frecuencia de casos que cumplieron con el tratamiento farmacológico en pacientes colombianos con hipertensión arterial, enfermedad cerebrovascular, diabetes mellitus, asma, enfermedad pulmonar obstructiva crónica y dislipidemia, entre el 2005 y el 2022.Materiales y métodos. Se llevó a cabo una revisión sistemática de la literatura y un metaanálisis de los estudios identificados mediante las bases de datos Medline y LILACS para sintetizar cuantitativamente el porcentaje de cumplimiento del tratamiento.Resultados. Catorce estudios cumplieron los criterios de inclusión y se analizaron 5.658 pacientes. El cumplimiento del tratamiento fue del 59 %, con una heterogeneidad alta entre los estudios incluidos (IC95 % = 46-71 %; I2 = 98,8 %, p<0,001). Se obtuvo un mayor cumplimiento para la diabetes mellitus (79 %; IC95 % = 65-90 %) y la dislipidemia (70 %; IC 95 % = 66-74 %). En los pacientes con hipertensión arterial el cumplimiento fue del 51 % (IC 95 % = 31-72 %).Conclusiones. La revisión sistemática muestra un bajo cumplimiento de las recomendaciones sobre el manejo farmacológico de enfermedades crónicas no transmisibles, lo que puede repercutir en los resultados clínicos y en la carga de la enfermedad a largo plazo.

May Measurement Month 2019: an analysis of blood pressure screening results from Colombia.

Hypertension awareness and control is poor in low- and middle-income countries. Thus, implementing strategies to increase hypertension detection is needed. Colombia participated as one of the 92 countries involved in the third campaign of the May Measurement Month in 2019. Blood pressure (BP) was measured in 48 324 volunteers from 13 departments in Colombia. In total, 27.9% individuals were identified with hypertension. Of those with hypertension, 63.7% were aware of their condition, 60.0% were on antihypertensive medication, and 38.4% had controlled BP. These results showed low levels of awareness, treatment, and control of hypertension in this sample of subjects volunteered to participate, suggest the urgent necessity of implementing programmes to improve the diagnosis and management of hypertension in Colombia.

The SIMAC study: A randomized controlled trial to compare the effects of resistance training and aerobic training on the fitness and body composition of Colombian adolescents.

The aim of this study was to evaluate the impact on muscle strength, aerobic fitness and body composition, of replacing the physical education (PE) class of Colombian adolescents with resistance or aerobic training. 120 tanner stage 3 adolescents attending a state school were randomized to resistance training, aerobic training, or a control group who continued to attend a weekly 2- hour PE class for 16 weeks. The resistance training and aerobic training groups participated in twice weekly supervised after-school exercise sessions of < 1 hour instead of their PE class. Sum of skinfolds, lean body mass (bioelectrical impedance analysis), muscular strength (6 repetition maximum (RM)) bench press, lateral pulldown and leg press) and estimated cardiorespiratory fitness (multistage 20 meter shuttle run) were assessed at pre and post intervention. Complete data were available for n = 40 of the resistance training group, n = 40 of the aerobic training group and n = 30 PE (controls). Resistance training attenuated increases in sum of skinfolds compared with controls (d = 0.27, [0.09-0.36]). We found no significant effect on lean body mass. Resistance training produced a positive effect on muscle strength compared with both controls (d = 0.66 [.49-.86]) and aerobic training (d = 0.55[0.28-0.67]). There was a positive effect of resistance training on cardiorespiratory fitness compared with controls (d = 0.04 [-0.10-0.12]) but not compared with aerobic training (d = 0.24 [0.10-0.36]). Replacing a 2-hour PE class with two 1 hour resistance training sessions attenuated gains in subcutaneous adiposity, and enhanced muscle strength and aerobic fitness development in Colombian youth, based on a median attendance of approximately 1 session a week. Further research to assess whether adequate stimuli for the development of muscular fitness exists within current physical education provision is warranted.

Análisis de diversas variables polisomnográficas y su relación con la severidad del síndrome de apnea e hipoapnea obstructiva del sueño / The analysis of polysomnographic variables and their relation with severity of obstructive sleep apnea and hypopnea syndrome

genera obstrucción de la vía aérea superior, y el estándar de oro para su diagnóstico es la polisomnografía (PSG). Objetivo: esclarecer la relación que existe entre las variables polisomnográficas y la severidad de la enfermedad, para tener más elementos objetivos al determinar el manejo y el seguimiento médico. Diseño: estudio observacional analítico de corte transversal. Metodología: se analizaron las variables polisomnográficas de 575 pacientes mediante el software STATA® VE 15.0; con la prueba Kruskal Wallis se evaluó la relación entre estas y la severidad. Resultados: la prevalencia de SAHOS en la cohorte fue de 73,04 %; a mayor duración media de apnea MAD se encontraron peores datos de SaO2. La media de Ct90 en pacientes sanos fue 2,55 %. La MAD en pacientes con SAHOS moderado y severo fue de 21 segundos, mientras que el REM IAH, el Ct90 y la duración máxima de apneas tuvieron buena relación con el IAH. Conclusiones: los microdespertares, el Ct90, la SaO2 mínima, la MAD y la frecuencia cardíaca máxima están relacionados de manera importante con la severidad de la enfermedad. El WASO, la duración mínima de apneas, la vigilia antes del sueño y la frecuencia cardíaca mínima no están relacionados. Las apneas de larga duración por encima de 18,5 segundos se asociaron significativamente a peores cifras de oxigenación. Los números de microdespertares tienen una relación fuerte con la severidad de la enfermedad y la más fuerte con los datos de peor oxigenación.

Introduction: The obstructive sleep apnea/Hypopnea syndrome (OSAHS) generates obstruction of the upper air way and the gold standard for its diagnosis is the polysomnography. Objective: To clarify the relation between the polysomnographic variables and the severity of the condition in order to have more objective elements to help choose the best management and medical follow up. Design: Cross-Sectional, analytical and observational study. Methodology: The polysomnographic variables of 575 patients were analyzed using STATA® VE 15.0 software. The relation between the variables and their severity were evaluated using the Kruskall Wallis Test. Results: The prevalence of the (OSAHS) in the cohort was 73.04 %, to longer MADs lowest SaO2 data, the media of Ct90 in healthy patients was 2.55 %. The media MAD for patients with moderate and severe OSA was 21 seconds. The REM IAH, Ct90 and maximum duration of apnea had a strong relation with the IAH. Conclusions: The arousals, the Ct90, the lowest SaO2, the MAD and the maximum cardiac frequency are crucially related to the severity of the condition. The WASO, the minimum duration of the apneas, the vigil before sleep and the minimum cardiac frequency are not related. The apneas with the longest duration, above 18.5 seconds, are significantly associated with the worst numbers of oxygenation. The number of arousals is strongly linked to the severity of the disease being the most severe related to the data associated with the worst oxygenation.

[Concordance of the assessment of pubertal development with the Tanner scale between adolescents and a trained physician]. / Concordancia en la evaluación del desarrollo puberal mediante la escala de Tanner entre adolescentes y un médico entrenado.

OBJECTIVES.: To assess the concordance between self-assessment of pubertal development with the Tanner scale performed by adolescents compared to the assessment performed by a trained physician. MATERIALS AND METHODS.: As part of the SIMAC project, data was collected on 244 adolescents. At baseline, we included an anthropometric and pubertal development assessment, with a self-assessment by the participants. RESULTS.: We included 229 teenagers from 12 to 17 years old. The agreement between the self-assessment and the clinical evaluation with the Tanner scale presented an 88.3% agreement and a weighted kappa coefficient of 0.554. The self-assessment in women showed a good agreement ( kappaweighted=0.653) and in men a moderate agreement (kappaweighted=0.464). The only variable with a significant influence on the agreement ability was gender; the disagreement probability in males was 63% greater than in females, regardless of age, height, or weight (95% CI: 1,18-2, 26). CONCLUSIONS: . Self-assessment was not accurate enough to replace medical examination, especially in males. More research is needed on this subject considering the impact that self-assessment of sexual development could have.

OBJETIVOS.: Evaluar la concordancia entre la autoevaluación del desarrollo puberal mediante la escala de Tanner realizada por adolescentes, comparado con la evaluación efectuada por un médico entrenado. MATERIALES Y MÉTODOS.: Los datos de 244 adolescentes fueron recolectados como parte del proyecto SIMAC. En la línea de base incluimos una evaluación antropométrica y del desarrollo puberal, con una autoevaluación por parte de los participantes. RESULTADOS.: Incluimos 229 adolescentes de 12 a 17 años. La concordancia entre la autoevaluación y la evaluación clínica de la escala de Tanner presentó un acuerdo obtenido de 88,3% y un coeficiente kappa ponderado de 0,554. La autoevaluación en mujeres demostró una concordancia buena (kappapond=0,653), y en varones una concordancia moderada (kappapond=0,464). La única variable con una influencia significativa sobre la capacidad de acuerdo fue el sexo; la probabilidad de desacuerdo en los varones fue 63% mayor que en las mujeres, independiente de edad, talla y peso (IC 95%:1,18-2,26). CONCLUSIONES.: La autoevaluación no fue lo suficientemente precisa para reemplazar el examen médico, sobre todo en los varones. Se requieren más estudios en relación con este tema, reconociendo el impacto que podría llegar a tener la autoevaluación del desarrollo sexual.

May Measurement Month 2017: an analysis of blood pressure screening results in Colombia-Americas.

Despite the availability of efficient methods to evaluate blood pressure (BP) and of safe and efficient medication to treat and control hypertension, the levels of awareness, treatment and control are very low globally, particularly in low- and middle-income countries. To highlight the importance of improving these rates, the International Society of Hypertension (ISH) endorsed by the World Hypertension League have implemented the May Measurement Month initiative. We present here the results obtained in Colombia. The Fundación Oftalmológica de Santander (FOSCAL) led the implementation of this strategy in Colombia and 11 departments participated. The data collection followed the guidelines of the ISH. The information collected was compiled for the report generation and the submission to the Technical Secretariat of the ISH. Data cleaning was performed locally by FOSCAL. Data were collated and analysed centrally. A total of 22 258 participants (58.8% female) were included in the analysis. Mean age was 40.9 ± 17.7 years. Age and sex-standardized BP excluding participants receiving BP medications was 118/74.3 mmHg, and in those on treatment 125/78 mmHg. High BP was present in 5036 (22.8%) individuals, 1637 of 18 644 (8.8%) who were not receiving anti-hypertensive medications were hypertensive, and 961 of 3359 (28.6%) receiving treatment were not controlled. These results highlight the need to develop innovative promotion strategies at individual and population levels to increase the awareness of the importance of BP, and the consequences of not having well-controlled hypertension. This initiative is an effective and easy to implement strategy that should be maintained in the coming years.

Control y tratamiento de la hipertensión arterial: Programa 20-20 / Control and treatment of arterial hypertension; Program 20-20

Resumen Las enfermedades cardiovasculares son la primera causa de muerte prematura en el mundo y entre los factores de riesgo modificables más prevalentes se encuentra la hipertensión arterial, que es la tercera causa de muerte en el mundo, atribuyéndosele una de cada ocho muertes a nivel global. La hipertensión arterial se identifica fácilmente a través de métodos no invasivos; estudios poblacionales mundiales han mostrado que la prevalencia de hipertensión arterial en adultos mayores de 35 años es de 41%, de los cuales solamente el 46,5% son conscientes de ser hipertensos y de aquellos que son conscientes el 87,9% está recibiendo tratamiento farmacológico, pero solo el 32.5% de los que reciben tratamiento está bien controlado para una cifra de control global de apenas el 18%. En este artículo se revisan los factores que explican esta situación, entre ellos dificultades asociadas a la disponibilidad y al acceso a los servicios de salud y a los medicamentos antihipertensivos, educación de los equipos de salud y falta de consciencia de los pacientes respecto a su enfermedad, lo que determina una baja adherencia a las intervenciones de cambios de estilos de vida y a la terapia farmacológica. Así mismo, se revisan una serie de iniciativas y estrategias que están siendo desarrolladas por diferentes organizaciones en pro de mejorar la detección, el diagnóstico, el tratamiento y el control adecuado de la hipertensión arterial, de tal manera que se contribuya a disminuir sustancialmente la morbimortalidad por enfermedades cardiovasculares.

Abstract Cardiovascular diseases are the first cause of premature death in the world. Arterial hypertension is among the most prevalent modifiable diseases, and is the third cause of death in the world, with one in every eight deaths worldwide being attributed to it. Arterial hypertension is easily to identify using non-invasive methods. World population studies have shown that the prevalence of arterial hypertension in adults greater than 35 years is 41%, and only 46.5% are aware of being hypertensive. In those that are aware, 87.9% are receiving pharmacological treatment, but only 32.5% of those that receive treatment are well-controlled, with an overall control worldwide of just 18%. In this article, the factors that explain this situation are reviewed, including the difficulties associated with the availability and access to health services and anti-hypertensive medication, education of the health teams, and lack of awareness by the patients as regards their illness. This is reflected by a low adherence to the interventions on changes in life style and the pharmacological treatment. Furthermore, a review is carried out on a series of initiatives and strategies that are being developed by different organisations in order to improve the adequate detection, treatment, and control of arterial hypertension, as such that it contributes to substantially decrease the morbidity and mortality due to cardiovascualar diseases.

Reevaluating nutrition as a risk factor for cardio-metabolic diseases.

INTRODUCTION: The consumption of saturated fats is considered a risk factor for cardiovascular diseases. OBJECTIVE: Review published papers on the role of macro-nutrient intake in cardiovascular risk. RESULTS: Recent reports from the PURE study and several previous meta-analyses, show that the consumption of total saturated and unsaturated fat is not associated with risk of acute myocardial infarction or mortality due to cardiovascular disease. High carbohydrate intake was associated with the highest risk of total and cardiovascular mortality, while total fat consumption or of its different types was associated with a lower risk of mortality. A high consumption of fruits, vegetables and legumes was associated with lower risk of total mortality and non-cardiovascular mortality. The consumption of 100 g of legumes, two or three times a week, ameliorated deficiencies of the nutrients contained in these foods and was associated with a reduction in the risk of developing chronic non-communicable diseases. CONCLUSION: A healthy diet should be balanced and varied, be composed of a proportion of complex carbohydrates rich in fibber between 50-55% of the daily energy consumed, of saturated and unsaturated fat (25-30%), animal and vegetable protein (including legumes) between 15-25%, vitamins, minerals and water. These nutrients are abundantly present in fruits, vegetables, cereals, legumes, milk and its derivatives, eggs and meats, so public policies should promote the availability and access to these nutrients within primary prevention programs to reduce the growing prevalence of cardio-metabolic diseases.

INTRODUCCIÓN: El consumo de grasas saturadas es considerado como un factor de riesgo para enfermedades cardiovasculares. OBJETIVO: Revisar trabajos publicados sobre el papel de la ingesta de macro-nutrientes en el riesgo cardiovascular. RESULTADOS: Varios meta-análisis y reportes del estudio PURE demuestran que el consumo de grasa total, saturada e insaturada, no se asoció con riesgo de infarto agudo de miocardio o mortalidad por enfermedad cardiovascular. La alta ingesta de carbohidratos fue la que se asoció con mayor riesgo de mortalidad total y cardiovascular, mientras que el consumo de grasa total o de sus diferentes tipos se asoció con menor mortalidad. Un alto consumo de frutas, vegetales y legumbres se asoció con menor riesgo de mortalidad total y mortalidad no cardiovascular. El consumo de 100 g de leguminosas, dos o tres veces por semana contribuyó a mejorar las deficiencias de nutrientes contenidos en estos alimentos y está asociado con una disminución del riesgo de desarrollar enfermedades crónicas no transmisibles. CONCLUSIÓN: Una dieta saludable debe ser equilibrada y variada, estar compuesta con una proporción de carbohidratos complejos ricos en fibra entre 50-55 % de la energía diaria consumida, de grasa saturada e insaturada (25-30 %), proteína animal y vegetal (incluidas las leguminosas) entre 15-25 %, vitaminas, minerales y agua. Estos nutrientes están abundantemente presentes en frutas, vegetales, cereales, leguminosas, leche y sus derivados, huevos y carnes, por lo que las políticas públicas deben promover la disponibilidad y acceso a estos nutrientes dentro de los programas de prevención primaria para disminuir la creciente prevalencia de enfermedades cardio-metabólicas.

La prescripción de inhibidores de la dipeptidil peptidasa-4 fue 7 % y la frecuencia de prescripción de agonista del receptor del péptido similar al glucagón tipo 1 (AR GLP-1) fue de 2 %. El medicamento con mayor frecuencia de prescripción como monoterapia fueron las biguanidas (22 %). La combinación más frecuente fue biguanida y las sulfonilureas (21 %), seguida de biguanida e insulina (10 %), y otras combinaciones. El 27 % pacientes con DM2 no recibió ningún tratamiento farmacológico para la diabetes. Con respecto a los medicamentos para comorbilidades, el 52 % de los pacientes utiliza al menos un tipo de antihipertensivo, el 39 % usa al menos un tipo de hipolipemiante y el 35 % utiliza ácido acetilsalicílico. Conclusiones: Las biguanidas fueron el medicamento con mayor frecuencia de prescripción, seguido de las sulfonilureas. Uno de cada cuatro pacientes no tenía registro de prescripción de medicamentos. El uso de ácido acetilsalicílico como prevención del riesgo cardiovascular fue menor al esperado.

Abstract Objetive: to describe the patterns of medicine prescriptions for diabetes mellitus type 2 (dm2) and the comorbidity of patients in five health care institutions in Colombia. Methodology: descriptive cross-sectional study carried out checking the medical records of 5098 patients with dm2 treated at the outpatient service centers in five Colombian cities between January 1 and December 31 of 2014. Each patient with dm2 had a record of at least two outpatient appointments registered during the time of this study. The information was collected through electronic surveys. National and international guides on diabetes treatment were used to categorize the medications. The spss® 21 software was used to analyze the data. Results: the most frequently prescribed medications were biguanides (59%) and sulfonylureas (28%). The prescription of inhibitors for Dipeptidyl peptidase-4 was 7% and the frequency of prescription of glucagon-like peptide-1 receptor agonists (ar glp-1) was 2%. The medication with the highest frequency of prescription as monotherapy were biguanides (22%). The most frequent combination was biguanide and sulfonylureas (21%). The second most frequent combination was biguanide with insulin (10%), and other combinations. 27% of patients with dm2 did not receive any pharmacological treatment for diabetes. Regarding the medicines for comorbidity, 52% of patients use at least one type of antihypertensive drug, 39% use at least one type of hypolipidemic drug and 35% uses acetylsalicylic acid. Conclusions: biguanides were the most frequently prescribed medication, sulfonylureas came after. One in four patients did not have a record of medicine prescription. The prescription of acetylsalicylic acid to prevent cardiovascular risk was lower than expected.

Rationale and design of a cluster randomized trial of a multifaceted intervention in people with hypertension: The Heart Outcomes Prevention and Evaluation 4 (HOPE-4) Study.

BACKGROUND: Cardiovascular disease is the leading cause of death throughout the world, with the majority of deaths occurring in low- and middle-income countries. Despite clear evidence for the benefits of blood pressure reduction and availability of safe and low-cost medications, most individuals are either unaware of their condition or not adequately treated. OBJECTIVE: The primary objective of this study is to evaluate whether a community-based, multifaceted intervention package primarily provided by nonphysician health workers can improve long-term cardiovascular risk in people with hypertension by addressing identified barriers at the patient, health care provider, and health system levels. METHODS/DESIGN: HOPE-4 is a community-based, parallel-group, cluster randomized controlled trial involving 30 communities (1,376 participants) in Colombia and Malaysia. Participants ≥50 years old and with newly diagnosed or poorly controlled hypertension were included. Communities were randomized to usual care or to a multifaceted intervention package that entails (1) detection, treatment, and control of cardiovascular risk factors by nonphysician health workers in the community, who use tablet-based simplified management algorithms, decision support, and counseling programs; (2) free dispensation of combination antihypertensive and cholesterol-lowering medications, supervised by local physicians; and (3) support from a participant-nominated treatment supporter (either a friend or family member). The primary outcome is the change in Framingham Risk Score after 12 months between the intervention and control communities. Secondary outcomes including change in blood pressure, lipid levels, and Interheart Risk Score will be evaluated. SIGNIFICANCE: If successful, the study could serve as a model to develop low-cost, effective, and scalable strategies to reduce cardiovascular risk in people with hypertension.

Reevaluating nutrition as a risk factor for cardio-metabolic diseases

Introduction: The consumption of saturated fats is considered a risk factor for cardiovascular diseases. Objective: Review published papers on the role of macro-nutrient intake in cardiovascular risk. Results: Recent reports from the PURE study and several previous meta-analyses, show that the consumption of total saturated and unsaturated fat is not associated with risk of acute myocardial infarction or mortality due to cardiovascular disease. High carbohydrate intake was associated with the highest risk of total and cardiovascular mortality, while total fat consumption or of its different types was associated with a lower risk of mortality. A high consumption of fruits, vegetables and legumes was associated with lower risk of total mortality and non-cardiovascular mortality. The consumption of 100 g of legumes, two or three times a week, ameliorated deficiencies of the nutrients contained in these foods and was associated with a reduction in the risk of developing chronic non-communicable diseases. Conclusion: A healthy diet should be balanced and varied, be composed of a proportion of complex carbohydrates rich in fibber between 50-55% of the daily energy consumed, of saturated and unsaturated fat (25-30%), animal and vegetable protein (including legumes) between 15-25%, vitamins, minerals and water. These nutrients are abundantly present in fruits, vegetables, cereals, legumes, milk and its derivatives, eggs and meats, so public policies should promote the availability and access to these nutrients within primary prevention programs to reduce the growing prevalence of cardio-metabolic diseases.

Introducción: El consumo de grasas saturadas es considerado como un factor de riesgo para enfermedades cardiovasculares. Objetivo: Revisar trabajos publicados sobre el papel de la ingesta de macro-nutrientes en el riesgo cardiovascular. Resultados: Varios meta-análisis y reportes del estudio PURE demuestran que el consumo de grasa total, saturada e insaturada, no se asoció con riesgo de infarto agudo de miocardio o mortalidad por enfermedad cardiovascular. La alta ingesta de carbohidratos fue la que se asoció con mayor riesgo de mortalidad total y cardiovascular, mientras que el consumo de grasa total o de sus diferentes tipos se asoció con menor mortalidad. Un alto consumo de frutas, vegetales y legumbres se asoció con menor riesgo de mortalidad total y mortalidad no cardiovascular. El consumo de 100 g de leguminosas, dos o tres veces por semana contribuyó a mejorar las deficiencias de nutrientes contenidos en estos alimentos y está asociado con una disminución del riesgo de desarrollar enfermedades crónicas no transmisibles. Conclusión: Una dieta saludable debe ser equilibrada y variada, estar compuesta con una proporción de carbohidratos complejos ricos en fibra entre 50-55 % de la energía diaria consumida, de grasa saturada e insaturada (25-30 %), proteína animal y vegetal (incluidas las leguminosas) entre 15-25 %, vitaminas, minerales y agua. Estos nutrientes están abundantemente presentes en frutas, vegetales, cereales, leguminosas, leche y sus derivados, huevos y carnes, por lo que las políticas públicas deben promover la disponibilidad y acceso a estos nutrientes dentro de los programas de prevención primaria para disminuir la creciente prevalencia de enfermedades cardio-metabólicas.

Clinical outcomes of patterned laser trabeculoplasty as adjuvant therapy in open angle glaucoma and ocular hypertension.

AIM: To assess the efficacy and safety of patterned laser trabeculoplasty (PLT) as an adjunctive treatment in open angle glaucoma (OAG) or ocular hypertension (OHT) patients who were under antiglaucoma medical treatment. METHODS: This study was a retrospective review of primary or secondary OAG patients and OHT patients with medically uncontrolled (≥18 mm Hg) intraocular pressure (IOP) who underwent 360° PLT from June 2016 to August 2016. Follow-up visits at week 1, and 1, 3 and 6mo were performed. IOP, best corrected visual acuity (BCVA), complications and eye drop glaucoma medication were recorded at each follow-up visit. Success was defined as IOP reduction ≥20% from baseline. RESULTS: Forty-one eyes of 25 patients were included in this study. Pre-treatment mean IOP was 20.2±1.6 mm Hg. After PLT, IOP was 19.3±5.2, 16.1±2.7, 17.1±3.7 and 16.3±3.5 mm Hg, at 1wk, 1, 3 and 6mo, respectively. IOP reduction from baseline was statistically significant from the first month, remaining stable at 6mo (P<0.001). PLT success at 6mo of follow-up was 48.78%. The number of glaucoma medication per eye (P=0.10) and the mean BCVA both remained constant (P=0.37). Complications included transient IOP spikes in 4 eyes (9.8%) and peripheral anterior synechiae in 7 eyes (17.1%). CONCLUSION: PLT is an effective and safe method for the management of patients with OHT or OAG as an adjunctive therapy. Additional larger studies should be designed to verify the long-term stability of IOP reduction with this laser technology.

Validation of the Beck Hopelessness Scale in patients with suicide risk. / Validación de la Escala de Desesperanza de Beck en pacientes con riesgo suicida.

INTRODUCTION: Only a few scales have been validated in Spanish for the assessment of suicide risk, and none of them have achieved predictive validity. OBJECTIVE: To determine the validity and reliability of the Beck Hopelessness Scale in patients with suicide risk attending the specialist clinic. METHODS: The Beck Hopelessness Scale, reasons for living inventory, and the suicide behaviour questionnaire were applied in patients with suicide risk attending the psychiatric clinic and the emergency department. A new assessment was made 30 days later to determine the predictive validity of suicide or suicide attempt. RESULTS: The evaluation included a total of 244 patients, with a mean age of 30.7±13.2 years, and the majority were women. The internal consistency was .9 (Kuder-Richardson formula 20). Four dimensions were found which accounted for 50% of the variance. It was positively correlated with the suicidal behaviour questionnaire (Spearman .48, P<.001), number of suicide attempts (Spearman .25, P<.001), severity of suicide risk (Spearman .23, P<.001). The correlation with the reasons for living inventory was negative (Spearman -.52, P<.001). With a cut-off ≥12, the negative predictive value was 98.4% (95% CI: 94.2-99.8), and the positive predictive value was 14.8% (95% CI: 6.6-27.1). CONCLUSION: The Beck Hopelessness Scale in Colombian patients with suicidality shows results similar to the original version, with adequate reliability and moderate concurrent and predictive validity.

Corneal Power Determination with Corneal Tomography after Refractive Surgery with Excimer Laser / Determinación del poder corneal con un tomógrafo corneal luego de cirugía refractiva con láser excimer / Determinação da potência corneana com uma topografia de córnea após cirurgia refrativa com excimer láser

Introduction. Corneal power determination after refractive surgery with excimer laser is complex. Different alternatives with the use of corneal tomography have been used for this measurement. Objective. To evaluate various methods of determination of corneal power in patients undergoing photorefractive surgery, including diagnostic tests with quantitative measurements. Methodology. This is a retrospective observational study. We included patients undergoing photorefractive surgery with refractive results and post-operative corneal tomography taken at least ten weeks after surgery. Results. In myopic eyes, significant differences were found in the value determined by the keratometry derived from the clinical history when compared with the average post-operative manual keratometry, the simulated 32keratometry and the Mean Pupil Power of the Sirius®tomograph. On another note, when averaging the mean post-operative manual keratometry with the post-operative Mean Pupil Power (value called Kpopaverage 1) and comparing it with the keratometry derived from the clinical history method, no statistically significant differences were observed in myopic patients. Likewise, when averaging the simulated post-operative keratometry of the Sirius® equipment with the post-operative Mean Pupil Power (value called "Kpop average 2") and comparing it with the keratometry derived by the method of the clinical history, no statistically significant differences were observed in myopic patients. On the other hand, in hyperopic eyes and those with mixed astigmatism, mean errors from post-operative Mean Pupil Power, in comparison to the keratometry derived by clinical history method, were not significantly different from the errors when comparing the "Kpop average 1" and the "Kpop average 2"with keratometry derived by the clinical history method. Conclusions. In myopic eyes the post-operative corneal power determinations with the "Kpop average 1" and "Kpop average 2" are closer to the keratometry derived by clinical history method than to measurements from the average post-operative manual keratometry, the post-operative simulated keratometry or the Mean Pupil Power of the Sirius® equipment.

Introducción. La determinación del poder corneal, después de la cirugía refractiva con láser excimer, es difícil. Diferentes alternativas con el uso de tomógrafos corneales se han utilizado para esta medición. Objetivo. Evaluar diversos métodos de determinación del poder corneal en pacientes operados de cirugía fotorrefractiva, incluyendo pruebas diagnósticas con medidas cuantitativas. Metodología. Estudio retrospectivo de pacientes operados de cirugía fotorrefractiva que tuvieran resultados refractivos y tomografía corneal post-operatoria al menos diez semanas luego de cirugía. Resultados. En los ojos miopes se encontraron diferencias significativas en el valor determinado por la queratometría derivada de la historia clínica al compararla con la queratometría manual promedio postoperatoria, la queratometría simulada y el Mean Pupil Power del tomógrafo Sirius®. Por otra parte, al promediar la queratometría manual promedio postoperatoria con el Mean Pupil Power postoperatorio (valor denominado Kpop promedio 1) y compararla con la queratometría derivada por el método de la historia clínica, no se observaron en los pacientes miopes diferencias estadísticamente significativas. Asimismo, al promediar la queratometría simulada postoperatoria del equipo Sirius® con el Mean Pupil Power postoperatorio (valor denominado Kpop promedio 2) y compararla con la queratometría derivada por el método de la historia clínica tampoco se observaron en los pacientes miopes diferencias estadísticamente significativas. Por otro lado, en los ojos hipermétropes y con astigmatismo mixto, los promedios de los errores del Mean Pupil Power postoperatorio, con respecto a la queratometría derivada por el método de la historia clínica, no fueron significativamente diferentes de los errores al comparar la Kpop promedio 1 y la Kpop promedio 2 con la queratometría derivada por el método de la historia clínica. Conclusiones. En ojos miopes las determinaciones del poder corneal postoperatorio con las Kpop promedio 1 y Kpop promedio 2 se aproximan más a la queratometría derivada por el método de la historia clínica que a las mediciones de la queratometría manual promedio postoperatoria, la queratometría simulada postoperatoria o el Mean Pupil Power del equipo Sirius®.

Introdução. A determinação da potência corneana, após a cirurgia refrativa com excimer láser, é difícil. Foram usadas diferentes alternativas com o uso de tomógrafos de córnea para esta medição. Objetivo. Avaliar vários métodos de determinação da potência corneana em pacientes submetidos à cirurgia fotorrefrativa, incluindo testes diagnósticos com medidas quantitativas. Métodos. Este é um estudo observacional retrospectivo. Foram incluídos pacientes submetidos à cirurgia fotorrefrativa com resultados refrativos e topografía corneana pós-operatória pelo menos um mês após a cirurgia. Resultados. Nos olhos míopes foram encontradas diferenças significativas no valor determinado pela ceratectomia derivada da história clínica, quando comparada com a média da ceratectomia manual pós-operátoria, a ceratectomia simulada e o Mean Pupil Power do tomógrafo Sirius®. Por outro lado, ao calcularmos a média da ceratectomia manual pós-operatória com o Mean Pupil Power pós-operatório (valor denominado Kpop média 1) e compará-la com a ceratectomia pelo método da história clínica, não foram observadas diferenças estatisticamente significantes nos pacientes miopes. Da mesma forma, ao calcular a média da ceratectomia pós-operatória simulada do equipamento Sirius® com o Mean Pupil Power pósoperatório (valor denominado Kpop média 2) e comparála com a ceratectomia derivada do método de história clínica, não foram observadas diferenças estatisticamente significantes nos pacientes miopes. Por outro lado, em olhos hipermetrópicos e com astigmatismo mixto, as médias de erros do Mean Pupil Power pós-operatório, em relação à ceratectomia derivada pelo método da história clínica, não foram significativamente diferentes dos erros na comparação do Kpop média 1 y la Kpop média 2 com a ceratectomia derivada pelo método da história clínica. Conclusões. Nos olhos míopes, as determinações de potência corneana pósoperatória com Kpop média 1 e Kpop média 2 estão mais próximas da ceratectomia derivada pelo método da história clínica do que das medidas de ceratectomia manual média pós-operatória, da ceratectomia simulada pós-operatória ou Mean Pupil Power do equipamento Sirius®.

Association Between Cigarette Smoking Prevalence and Income Level: A Systematic Review and Meta-Analysis.

INTRODUCTION: Previous evidence linked low socioeconomic status with higher smoking prevalence. Our objective was to assess the strength of this association in the world population, updating a previous work. METHODS: Systematic review and meta-analysis of observational studies. Subgroup analyses included continents, WHO regions, country mortality levels, gender, age, risk of bias, and study publication date. Independent reviewers selected studies, assessed potential bias and extracted data. We searched MEDLINE, EMBASE, CENTRAL, SOCINDEX, AFRICAN INDEX MEDICUS, and LILACS, and other sources from 1989 to 2013 reporting direct measurements of income and current cigarette smoking. RESULTS: We retrieved 13,583 articles and included 93 for meta-analysis. Median smoking prevalence was 17.8% (range 3-70%). Lower income was consistently associated with higher smoking prevalence (odds ratio [OR]: 1.45; 95% confidence interval [CI]: 1.35-1.56). This association was statistically significant in the subgroup analysis by WHO regions for the Americas (OR: 1.54; 95% CI: 1.42-1.68), South East Asia (OR: 1.53; 95% CI: 1.10-2.00), Europe (OR: 1.45; 95% CI: 1.29-1.63), and Western Pacific (OR: 1.32; 95% CI: 1.02-1.72), and in studies conducted during 1990s (OR: 1.42; 95% CI: 1.24-1.62) and 2000s (OR: 1.48; 95%CI: 1.30-1.64). Likewise, it was noted in low-mortality countries (OR: 1.48; 95% CI: 1.37-1.60) and for both genders. Prevalence was highest in the lowest income levels compared to the middle (OR: 1.69; 95% CI: 1.49-1.92), followed by the middle level compared to the highest (OR: 1.31; 95% CI: 1.20-1.43). CONCLUSIONS: Our results show that current cigarette smoking was significantly associated with lower income worldwide and across subgroups, suggesting a dose-response relationship. IMPLICATIONS: This unique updated systematic review shows a consistent inverse dose-response relationship between cigarette smoking and income level, present among most geographical areas and country characteristics. Public health measures should take into account this potential inequity and consider special efforts directed to disadvantaged populations.

Sociodemographic factors related to handgrip strength in children and adolescents in a middle income country: The SALUS study.

OBJECTIVE: To determine sociodemographic factors associated with handgrip (HG) strength in a representative sample of children and adolescents from a middle income country. METHODS: We evaluated youth between the ages of 8 and 17 from a representative sample of individuals from the Department of Santander, Colombia. Anthropometric measures, HG strength, and self-reported physical activity were assessed, and parents/guardians completed sociodemographic questionnairres. Multinomial logistic regression models were used to estimate the association between sociodemographic and anthropometric characteristics and tertiles of relative HG strength. We also produced centile data for raw HG strength using quantile regression. RESULTS: 1,691 young people were evaluated. HG strength increased with age, and was higher in males than females in all age groups. Lower HG strength was associated with indicators of higher socioeconomic status, such as living in an urban area, residence in higher social strata neighborhoods, parent/guardian with secondary education or higher, higher household income, and membership in health insurance schemes. In addition, low HG strength was associated with lower physical activity levels and higher waist-to-hip ratio. In a fully adjusted regression model, all factors remained significant except for health insurance, household income, and physical activity level. CONCLUSIONS: While age and gender specific HG strength values were substantially lower than contemporary data from high income countries, we found that within this middle income population indicators of higher socioeconomic status were associated with lower HG strength. This analysis also suggests that in countries undergoing rapid nutrition transition, improvements in socioeconomic conditions may be accompanied by reduction in muscle strength.

Is myopia another clinical manifestation of insulin resistance?

Myopia is a multifactorial visual refraction disease, in which the light rays from distant objects are focused in front of retina, causing blurry vision. Myopic eyes are characterized by an increased corneal curvature and/or ocular axial length. The prevalence of myopia has increased in recent decades, a trend that cannot be attributed exclusively to genetic factors. Low and middle income countries have a higher burden of refractive error, which we propose could be a consequence of a shorter exposure time to a westernized lifestyle, a phenomenon that may also explain the rapid increase in cardiometabolic diseases, such as diabetes, among those populations. We suggest that interactions between genetic, epigenetic and a rapidly changing environment are also involved in myopia onset and progression. Furthermore, we discuss several possible mechanisms by which insulin resistance may promote abnormal ocular growth and myopia to support the hypothesis that insulin resistance and hyperinsulinemia are involved in its pathogenesis, providing a link between trends in myopia and those of cardiometabolic diseases. There is evidence that insulin have direct ocular growth promoting effects as well an indirect effect via the induction of insulin-like growth factors leading to decreases insulin-like growth factor-binding protein, also implicated in ocular growth.
