Suicide ideation and psychotropic recreational drug use by adolescents: a systematic review and meta-analysis

ABSTRACT BACKGROUND: Adolescence is characterized by complex and dynamic changes, often involving experimentation, including the use of psychotropic substances. Although it is well-established that recreational psychotropic drugs are associated with suicide ideation in adults, evidence of this association in adolescents remains limited. OBJECTIVE: To investigate the relationship between suicide ideation and psychotropic recreational drug use among adolescents. DESIGN AND SETTING: Systematic review with meta-analysis developed at Universidade Federal de Uberlândia (UFU) and Universidade Estadual de Campinas (UNICAMP), Brazil. METHODS: A search across eight electronic databases for observational studies, without language or publication year restrictions, was conducted. The Joanna Briggs Institute tool was used to assess the risk of bias. Random-effects meta-analyses and odds ratios were used to measure the effects. RESULTS: The search yielded 19,732 studies, of which 78 were included in the qualitative synthesis and 32 in the meta-analysis. The findings indicated that suicidal ideation was 1.96 times more likely (95% confidence interval, CI = 1.47; 2.61) for adolescents who used some drug recurrently and 3.32 times more likely (95%CI = 1.86; 5.93) among those who abused drugs. Additionally, adolescents who used cannabis were 1.57 times more likely (95%CI = 1.34; 1.84) to experience suicide ideation compared with non-users, while cocaine users had 2.57 times higher odds (95%CI = 1.47; 4.50). CONCLUSIONS: Psychotropic recreational drug use is associated with suicidal ideation among adolescents regardless of current or previous use, abuse, or type of substance used. SYSTEMATIC REVIEW REGISTRATION: Registered in the PROSPERO database under the identification number CRD42021232360. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021232360.

Efficacy and safety analysis of intravitreal bio-similar products of bevacizumab in patients with macular edema because of retinal diseases

Purpose: The purpose of this study was to evaluate retrospectively the efficacy and safety profile of intravitreal injection of bevacizumab bio?similar product Zybev(Z) for macular edema because of retinal diseases. Methods: A retrospective analysis was conducted on patients with macular edema because of retinal diseases, who had been administered intravitreal injections of bio?similar bevacizumab at a tertiary eye care center. Changes in the retinal thickness and visual acuity were evaluated to judge the efficacy, and adverse events were noted for the safety profile over a period of 6 weeks. Results: A total of 104 patients were included in the study. The mean age of the patients was 53 ± 13.5 years. The mean pre?injection best corrected visual acuity (BCVA) was 1.32 ± 0.70 log minimum angle of resolution (logMAR) with a central subfield thickness (CST) of 429.26 ± 204.30 ?m, and the post?injection BCVA at 6 weeks was 1.13 ± 0.71 logMAR with a CST of 302.26 ± 104.50 ?m; this change was statistically significant (P < 0.05) for all groups. The mean average cube thickness (?m) decreased from 11.85 ± 1.96 pre?injection to 10.52 ± 1.75 post?injection, and the mean average cube volume (mm3) decreased from 329.30 ± 54.35 to 302.23 ± 49.56 (P < 0.05). During the follow?up period after injection, no patient had inflammation, endophthalmitis, an increase in intra?ocular pressure, or systemic side effects. Conclusion: This short?term retrospective analysis provides evidence regarding the efficacy and safety of intravitreal injection of bio?similar products of bevacizumab for the treatment of macular edema because of retinal diseases

Application of similar drug dispensing mode in drug dispensing management / 中国药房

OBJECTIVE To provide reference for improving the dispensing accuracy of similar drugs and reducing dispensing error risk through exploring the dispensing mode of similar drugs. METHODS The effectiveness and feasibility of the similar drug dispensing management mode was explored through adjusting the traditional horizontal or vertical sorting method to a “Z” shaped cargo location sorting， implementing similar drug in different zones dispensed by different people， and combining measures such as adjusting the format of drug dispensing documents and improving inventory methods. The role of similar drug dispensing mode in drug dispensing management was evaluated comprehensively from two aspects： work quality and work efficiency. RESULTS After the implementation of similar drug dispensing mode， total number of monthly dispensing errors （18.42±8.79 vs. 28.50±6.87，P= 0.005） and the proportion of monthly dispensing errors of similar drugs （[ 4.17±5.71）% vs. （10.96±7.05）%，P＝0.017] were significantly lower than before the implementation； the monthly consistency rate between accounts and materials （[ 98.46±0.73）% vs. （97.61±0.57）%， P＝0.004] was significantly higher than before implementation； completion time of dispensing in each batch was not significantly affected， and daily work was carried out smoothly and orderly. CONCLUSIONS The similar drug dispensing mode has a significant effect in improving the accuracy of dispensing similar drugs， reducing the risk of dispensing errors， and does not affect the efficiency of dispensing work.

Post-market technical evaluation of dietary supplements based on domestic and foreign experiences / 上海预防医学

The paper is to explore how to carry out post-market technical evaluation of dietary supplements in China by referring to the experiences at home and abroad. Experiences of major countries and regions in the post-market evaluation of similar products of dietary supplements and China’s experience in drugs were systematically reviewed. Combined with the actual situation of the health food industry in China， suggestions were put forward for the post-market technical evaluation of health foods in China. There are many useful experiences worth learning from， such as the mandatory reporting responsibility of enterprises in the United States， a special scientific committee which provides long-term technical support in the European Union， post-market monitoring by enterprises in Australia， the establishment of relevant monitoring systems in Taiwan， the relatively mature regulatory system， evaluation system and management system in the field of drugs and medical devices， and the establishment of adverse reaction monitoring bases in the field of cosmetics， the responsibility of post-mark adverse reaction monitoring of food for special medical purposes by medical institutions， and the post-market management in various fields giving priority to safety. In combination with the current situation of China’s health food industry， five specific suggestions， such as promoting the construction of laws and regulations， are put forward.

Time partitioning among neotropical frugivorous bats: effects of phylogeny, body size, and abundance / Distribución del tiempo entre murciélagos frugívoros neotropicales: efectos de la filogenia, el tamaño corporal y la abundancia

Abstract Introduction: Resource partitioning by promoting coexistence is essential to determine species richness and composition in natural communities. However, the partitioning of time has been questioned as a mechanism that promotes the coexistence of ecologically similar species. Objective: To determine the importance of the partitioning of time as a mechanism that promotes coexistence, we compared the activity patterns of tropical frugivorous bats. Methods: We captured bats with mist nets from sunset to sunrise in three study sites (tropical dry forest, wet forest, and rainforest) to calculate activity patterns of the species using Kernel density estimation. We used the superposition coefficient (Δ1) to compare activity patterns between (1) bat assemblages of study sites, (2) frugivorous species in the same site, and (3) populations of the same species among different sites. To determine whether the overlap in the activity patterns was related to the ecological similarity of species, we evaluated the association between Δ1 and similarity in abundances and body mass and phylogenetic closeness. Results: We found geographical variations in the overall activity patterns of the assemblages of the three localities. Likewise, we found variations in activity patterns between species at each study site and between populations in different study sites. Overlap in activity patterns tended to decrease as species were phylogenetically more closely related and similar in abundance and body size. Conclusions: Our results provide empirical support for the role of temporal segregation in activity patterns as a mechanism that promotes the coexistence of ecologically similar species in nature.

Resumen Introducción: La partición de recursos es esencial para determinar la riqueza y composición de especies en las comunidades naturales. Sin embargo, la segregacion temporal ha sido cuestionada como un mecanismo que promueve la coexistencia de especies ecológicamente similares. Objetivo: Con el fin de determinar la importancia de la segregación en los patrones de actividad, como mecanismo que promueve la coexistencia; se compararon los patrones de actividad de murciélagos frugívoros neotropicales. Métodos: Se capturaron murciélagos con redes de niebla desde el atardecer hasta el amanecer en tres localidades (bosque seco tropical, bosque muy húmedo y bosque lluvioso submontano) con el fin de calcular los patrones de actividad de las especies empleando la estimación de densidad Kernel. Se utilizó el coeficiente de superposición (Δ) para comparar patrones de actividad entre: (1) ensamblajes de murciélagos de los sitios de estudio, (2) especies frugívoras en el mismo sitio, y (3) poblaciones de la misma especie en diferentes sitios. Resultados: Se encontraron variaciones geográficas en los patrones de actividad de los ensamblajes en las tres localidades. Asimismo, se encontraron variaciones en los patrones de actividad entre especies en cada sitio y entre poblaciones en diferentes sitios. Determinamos que la superposición en los patrones de actividad disminuyó a medida que las especies estaban más relacionadas filogenéticamente, similares en abundancia y tamaño corporal; lo que sugiere una tendencia hacia la segregación temporal de especies ecológicamente similares. Conclusión: Estos resultados proveen apoyo empírico del papel de la segregación temporal en los patrones de actividad como un mecanismo que promueve la coexistencia de especies ecológicamente similares en la naturaleza.

Rehabilitación del intestino utilizando un análogo semisintético del péptido 2 similar al glucagón. Primera experiencia con teduglutide en Uruguay / Intestinal rehabilitation using semisynthetic glucagon-like peptide-2 analogue. First experience with teduglutide in Uruguay / Reabilitação do intestino usando um análogo semi-sintético do peptídeo 2 semelhante ao glucagon. Primeira experiência com teduglutide no Uruguai

Resumen: La falla intestinal crónica (FIC) o tipo III es una condición invalidante, y la nutrición parenteral crónica (NPC) domiciliaria es el tratamiento que permite a estos pacientes mantenerse con vida. Sin embargo, solamente uno de cada tres países latinoamericanos cuentan con ese recurso, y sus complicaciones no son infrecuentes. Estas complicaciones son las principales indicaciones para trasplante intestinal, un procedimiento que en la mayoría de los países de ingresos medios no se ha desarrollado y no ha presentado los resultados esperados. En los últimos años, la rehabilitación intestinal a nivel mundial ha mejorado sustancialmente con el uso de análogos semisintéticos del péptido 2 similares al glucagón, existiendo cada vez mayor evidencia que demuestra la posibilidad de rehabilitación intestinal e independencia de la NPC con este fármaco, incluso en pacientes con anatomía desfavorable. Estos resultados han permitido mejorar la supervivencia y la calidad de vida de pacientes con FIC y, en muchas ocasiones, prescindir del trasplante. El paciente del caso que presentamos es el primero en recibir esta terapéutica en nuestro país. En este artículo analizamos la respuesta precoz favorable al tratamiento y sus perspectivas a futuro.

Abstract: Long-term home parenteral nutrition (HPN) is a life-saving treatment for patients with chronic intestinal failure, an invalidating condition. However, only 1 out of 3 countries can rely on this treatment and complications associated to chronic parenteral nutrition are rather frequent. The latter constitute the main indication for intestinal transplantion, a procedure that in most middle-income countries has not yet developed and has not shown the expected outcome. In recent years, intestinal rehabilitation has significantly improved at the global level with the use of GLP2, based on the growing evidence that proves the possibility of intestinal rehabilitation and independence from parenteral nutrition with Teduglutide, even in the case of patients with unfavorable anatomy. These results have caused a positive impact on survival and the quality of life of patients with chronic renal failure, and they can often abstain from transplant. The patient of the case study is the first one who received this therapy in our country and this article analyses his favorable early response to treatment and future perspectives.

Resumo: A insuficiência intestinal crônica (CIF) ou tipo III é uma condição incapacitante e a nutrição parenteral crônica (NPC) domiciliar é o tratamento que permite a sobrevida desses pacientes. No entanto, apenas 1 em cada 3 países latino-americanos dispõe desse recurso e as complicações da NPC não são raras. Essas complicações são as principais indicações para o transplante intestinal, procedimento que na maioria dos países de renda média não foi desenvolvido ou não apresentou os resultados esperados. Nos últimos anos, a reabilitação intestinal em todo o mundo tem melhorado substancialmente com o uso de sGLP2, com um número cada vez maior de evidências que mostram a possibilidade de reabilitação intestinal e independência da NPC, mesmo em pacientes com anatomia desfavorável. Esses resultados têm possibilitado prolongar a sobrevida e melhorar a qualidade de vida dos pacientes com CIF e, em muitos casos, dispensar o transplante. O paciente do caso que apresentamos é o primeiro a receber essa terapia em nosso país. Neste artigo, analisamos a resposta favorável ao tratamento precoce e suas perspectivas futuras.

Enfermedad nodular tiroidea en personas con diagnóstico de acromegalia / Nodular thyroid disease in people diagnosed with acromegaly

La aparición de nódulos tiroideos en las personas con acromegalia es una consecuencia de la elevación crónica de la hormona de crecimiento y el factor de crecimiento similar a la insulina tipo 1. Su naturaleza varía según la zona geográfica, suficiencia de yodo y antecedentes patológicos familiares, entre otros factores. No se han publicado estudios cubanos sobre la enfermedad nodular tiroidea en estas personas. Objetivos: Describir las características clínicas, bioquímicas y ultrasonográficas de la glándula tiroidea, según la presencia o no de la enfermedad nodular tiroidea. Métodos: Estudio observacional descriptivo, transversal, que incluyó 73 pacientes con acromegalia entre enero de 2003 y diciembre de 2017. Se estudiaron las variables: edad, sexo, color de la piel, antecedentes familiares de la enfermedad nodular tiroidea, niveles de la hormona de crecimiento, hormona estimulante del tiroides, T4 libre, anticuerpos contra la peroxidasa tiroidea y contra la tiroglobulina, volumen tiroideo, patrón ecográfico nodular y estudio citológico. Resultados: La enfermedad nodular tiroidea se presentó en el 75,3 por ciento de los casos, con predominio del bocio multinodular. La edad al diagnóstico fue menor en los pacientes con la enfermedad (43,53 ± 9,67), que en los que no la tenían (49,33 ± 6,96 años) (p = 0,02). La hormona de crecimiento al diagnóstico de acromegalia, resultó menor en los pacientes con este padecimiento (18,73 ± 11,33 µg/L vs. 35,91 ± 21,68 µg/L; (p = 0,00). El volumen tiroideo mostró diferencias significativas entre ambos grupos (14,2 ± 4,5 mL en los casos positivos de la enfermedad nodular tiroidea y 10,5 ± 2,8 mL en los casos negativos; p = 0,002), siendo el nódulo de baja sospecha de malignidad el más frecuente. El resto de las variables resultaron similares entre los pacientes con y sin la enfermedad. La citología se informó como benigna en el 75 por ciento en los nódulos únicos, el 80 por ciento de los bocios nodulares y el 90 por ciento de los bocios multinodulares (p = 0,51). Conclusiones: La enfermedad nodular tiroidea fue frecuente en los casos de acromegalia, y se asoció a la menor edad y los niveles inferiores de la hormona de crecimiento al diagnóstico. El bocio multinodular constituyó la forma clínica más frecuente y los parámetros hormonales y de autoinmunidad no se asociaron al tipo de la enfermedad nodular tiroidea(AU)

The appearance of thyroid nodules in people with acromegaly is a consequence of chronic elevation of growth hormone (GH) and insulin-like growth factor type 1 (IGF-1). Its nature varies according to the geographical area, the iodine sufficiency and family pathological history, among other factors. No Cuban studies on thyroid nodular disease (TND) in these people have been published. Objectives: Describe some clinical characteristics, as well as biochemical and ultrasonographic ones related to the thyroid gland, according to the presence or not of TND, and to identify the possible association of clinical, biochemical, ultrasonographic and cytological factors with the different types of TND in patients with acromegaly. Methods: A descriptive, cross-sectional observational study that included 73 patients with acromegaly between January 2003 and December 2017. The following variables were studied: age, sex, skin color, family history of TND, GH levels, thyroid stimulating hormone, free T4, antibodies against thyroid peroxidase and thyroglobulin, thyroid volume, nodular ultrasound pattern and cytological study. Results: TND occurred in 75.3 percent of cases, with a predominance of multinodular goiter. The age at diagnosis time was lower in patients with TND (43.53 ± 9.67) than in those who did not have it (49.33 ± 6.96 years) (p=0.02). GH at diagnosis time of acromegaly was lower in patients with TND (18.73±11.33µg/L vs 35.91±21.68µg/L; (p=0.00). The thyroid volume showed significant differences between both groups (14.2±4.5mL in positive cases of TND and 10.5±2.8mL in negative cases; p=0.002), being the most frequent the nodule with low suspicion of malignancy. The rest of the variables were similar between patients with and without TNDs. Cytology was reported as benign in 75 percent in single nodules, 80 percent of nodular goiters and 90 percent of multinodular goiters (p=0.51). Conclusions: TND was frequent in cases of acromegaly, and was associated with lower age and lower GH levels at diagnosis time. Multinodular goiter was the most frequent clinical form and hormonal and autoimmunity parameters were not associated with the type of TND(AU)

Síndrome de Doege Potter / Doege-Potter syndrome

Resumen El síndrome de Doege Potter es un síndrome caracterizado por hipoglucemia severa asociada a tumor fibroso de la pleura. Presentamos el caso de una paciente de 67 años con antecedente por biopsia de tumor fibroso de pleura, quien seis meses después de este diagnóstico presenta episodios de alteración del estado de conciencia con desorientación y documentación de hipoglucemia con triada de Whipple presente. Se realiza test de ayuno el cual es positivo para hipoglucemia no hiperinsulinémica y dado sus antecedentes, se hace el diagnóstico de un síndrome de Doege Potter. Se realiza manejo quirúrgico con resección total de masa tumoral con posterior resolución de la hipoglucemia.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1503).

Abstract Doege-Potter syndrome is characterized by severe hypoglycemia associated with a fibrous tumor of the pleura. We present the case of a 67-year-old patient with a history of a fibrous tumor of the pleura, diagnosed through biopsy, who six months after this diagnosis experienced episodes of altered consciousness with disorientation, and documented hypoglycemia with Whipple's triad. A fasting test was positive for non-hyperinsulinemic hypoglycemia and, given his history, he was diagnosed with Doege-Potter syndrome. He was treated surgically through total removal of the tumor mass, with subsequent resolution of the symptoms.(Acta Med Colomb 2020; 45. DOI:https://doi.org/10.36104/amc.2020.1503).

Cardiovascular disease risk markers in children under 10 years of age and their relationship with serum concentrations of IGF-1, IGFBP-1, IGFBP-2 and IGFBP-3 / Marcadores de riesgo cardiovascular en niños menores de 10 años y su relación con niveles séricos de IGF-1, IGFBP-1, IG-FBP-2 e IGFBP-3

Abstract Introduction: Any type of nutritional imbalance experienced during childhood will affect the health of an individual, both in their childhood and their adulthood. Several studies have proved that there is an association between cardiovascular disease (CVD) risk and endocrine and lipid markers at early stages of life. Objective: To establish the relationship between nutritional status (IGF-1 and serum levels of its binding proteins IGFBP-1, IGFBP-2 and IGFBP-3), and CVD risk markers in students aged 7 to 9 years. Materials and methods: Cross-sectional observational study conducted in 84 children attending two schools from Bogotá D.C. and Soacha, Colombia, to identify the relationship between possible variations in CVD risk markers and nutritional status. Sexual development stage, lipid profile, anthropometric data, blood sugar levels and IGF-1 and IGFBP serum levels of all participants were measured. Statistical analysis was conducted using the Pearson's correlation coefficient, the analysis of variance (ANOVA), and the Kruskall-Wallis, Games-Howell and Dunnett's tests. The confidence interval and statistical significance were 95% and p<0.05, respectively. Results: IGFBP-1 and IGFBP-2 levels proportionally decreased as weight increased. An inverse correlation between both proteins and triglyceride levels was found, as well as a direct correlation with HDL cholesterol levels. Conclusions: Alterations in CVD risk markers can be identified during childhood. If said alterations are timely detected, it is possible to adopt preventive and therapeutic actions such as the promotion of public policies aimed at preventing childhood overweight and obesity, which in turn will reduce the risk of developing cardiovascular disease in adulthood.

Resumen Introducción. Los desequilibrios nutricionales en la infancia afectan la salud tanto en la niñez como en la adultez. Estudios previos demuestran la asociación de marcadores endocrinos y lipídicos con riesgo cardiovascular (RCV) desde edades tempranas. Objetivo. Establecer la relación entre estado nutricional (niveles séricos de IGF-1 y sus proteínas enlazantes IGFBP-1, IGFBP-2 e IGFBP-3) y marcadores de RCV en estudiantes de 7 a 9 años. Materiales y métodos. Estudio observacional comparativo transversal realizado en 84 niños de 2 colegios de Bogotá D.C. y Soacha, Colombia, para identificar la relación entre posibles variaciones de marcadores de RCV y estado nutricional. Se midieron los niveles de glucemia y niveles séricos de IGF-1 e IGFBP, el nivel de desarrollo sexual, el perfil lipídico y los valores antropométricos. Para el análisis estadístico se utilizaron el coeficiente de correlación de Pearson, un análisis de varianza (ANOVA) y las pruebas de Kruskal Wallis, Games-Howell y Dunnett. El intervalo de confianza fue del 95% y la significancia estadística, de p<0.05. Resultados. La reducción en los niveles de IGFB-1 e IGFBP-2 fue directamente proporcional al aumento de peso. Por otra parte, se observó una correlación inversa entre ambas proteínas y concentraciones de triglicéridos, y una directa con los niveles colesterol HDL. Conclusiones. Las alteraciones de marcadores de RCV se pueden identificar en la infancia. Si estas son detectadas a tiempo es posible adoptar medidas preventivas y terapéuticas como la promoción de políticas públicas dirigidas prevenir el sobrepeso infantil, lo que a su vez reducirá el riesgo de padecer enfermedades cardiovasculares en edades adultas.

Impact of Kuntai Capsules on LIF, IGF-1 and EGF expression in the implantation window of endometrium in mice / Impacto de cápsulas de Kuntai en la expresión de LIF, IGF-1 y EGF en la ventana de implantación de endometrio en ratones

To investigate the influence of Kuntai capsules on the expression level of leukemia inhibitory factor (LIF), insulin-like growth factor-I (IGF-1)and epidermal growth factor (EGF) during the mouse's implantation window of superovulation period and controlled ovarian hyperstimulation period. 90 female mice were randomly divided into six groups in control, superovulation and controlled ovarian hyperstimulation (COH) conditions. The RNA expression of EGF, LIF and IGF-1 in the endometrium on the 4th day of pregnancy was detected, and the relative expression was compared. mRNA expression of these three factors in endometrium was significantly lower in superovulation and COH groups than control group (p<0.001). mRNA expression of these three factors in endometrium remained obviously lower in superovulation plus kuntai capsule group and COH plus kuntai capsule group than control group (p<0.01). mRNA expression of these three factors in endometrium was lower in control group than in the NS plus kuntai capsule group (p<0.05). Kuntai capsule cannot completely reverse the endometrial damages caused by superovulation and COH. Thus Kuntai capsule could partially improve a mouse's endometrial receptivity during the implantation window.

Para investigar la influencia de las cápsulas de Kuntai en el nivel de expresión del factor inhibidor de la leucemia (LIF), el factor de crecimiento similar a la insulina I (IGF-1) y el factor de crecimiento epidérmico (EGF) durante la ventana de implantación del ratón del período de superovulación y la hiperestimulación ovárica controlada período, se dividieron aleatoriamente 90 ratones hembra en seis grupos en condiciones de control, superovulación e hiperestimulación ovárica controlada (COH). Se detectó la expresión de ARN de EGF, LIF e IGF-1en el endometrio al cuarto día de embarazo, y se comparó la expresión relativa. La expresión de ARNm de estos tres factores en el endometrio fue significativamente menor en los grupos de superovulación y COH que en el grupo control (p<0,001). La expresión de ARNm de estos tres factores en el endometrio permaneció más baja en el grupo de cápsulas de superovulación más Kuntai y en el grupo de cápsulas de COH más Kuntai respecto del grupo control (p<0,01). La expresión de ARNm de estos tres factores en el endometrio fue menor en el grupo control que en el grupo de cápsula NS más Kuntai (p<0,05). La cápsula de Kuntai no pudo revertir completamente los daños endometriales causados por la superovulación y la COH. Por lo tanto, se sugiere que la cápsula de Kuntai podría mejorar parcialmente la receptividad endometrial de un ratón durante la ventana de implantación.

Association between metabolic syndrome and euthyroid nodular goiter: a case-control study / Asociación entre el síndrome metabólico y el bocio nodular eutiroideo: un estudio de casos y controles

Abstract Background: Metabolic syndrome is a cluster of metabolic abnormalities and abdominal obesity; its pathophysiologic basis, insulin resistance, has been shown to act as agent in thyroid cell proliferation. Few studies analyze the relationship between metabolic syndrome and thyroid nodular disease, with a substantial knowledge gap. Objective: Determine the association between metabolic syndrome and nodular thyroid disease in a region with adequate iodine intake. Methods: Case-control study. A total of 182 patients referred to radiology to undergo thyroid ultrasonography due to suspicion of thyroid disease. Cases had at least one thyroid nodule greater than 3 mm (n= 91). Controls did not have evidence of thyroid nodules (n= 91). Results: Bivariate analysis showed a significant association between metabolic syndrome and the presence of thyroid nodule (OR 2.56, 95% CI: 1.41-4.66, p <0.05). Low levels of HDL (OR 2.81, 95% CI: 1.54-5.12, p <0.05) and impaired fasting glucose (OR 2.05, 95%CI 1.10 to 3.78, p <0.05) were significantly associated with the presence of thyroid nodule, independent of the presence of metabolic syndrome. Multivariate analysis maintained the association between metabolic syndrome and thyroid nodule with an OR of 2.96 (95%CI 1.47 to 5.95, p <0.05); similarly, the associations of low levels of HDL (OR 2.77, 95%CI 1.44 to 5.3, p <0.05) and impaired fasting glucose (OR 2.23, 95%CI 1.14 to 4.34, p<0.05) with thyroid nodule remained significant. Conclusion: The thyroid nodular disease is associated with increased risk of metabolic syndrome, specifically decreased HDL and impaired fasting glucose levels were the factors that increased association was found.

Resumen Antecedentes: el síndrome metabólico es un conjunto de anormalidades metabólicas y obesidad abdominal; Se ha demostrado que su base fisiopatológica, la resistencia a la insulina, actúa como agente en la proliferación de las células tiroideas. Pocos estudios analizan la relación entre el síndrome metabólico y la enfermedad nodular tiroidea, con una brecha de conocimiento sustancial. Objetivo: determinar la asociación entre el síndrome metabólico y la enfermedad tiroidea nodular en una región con una ingesta adecuada de yodo. Métodos: estudio de casos y controles. Un total de 182 pacientes remitidos a radiología para someterse a una ecografía tiroidea debido a la sospecha de enfermedad tiroidea. Los casos tenían al menos un nódulo tiroideo mayor de 3 mm (n = 91). Los controles no tenían evidencia de nódulos tiroideos (n = 91). Resultados: El análisis bivariado mostró una asociación significativa entre el síndrome metabólico y la presencia de nódulo tiroideo (OR 2.56, IC 95%: 1.41-4.66, p <0.05). Los niveles bajos de HDL (OR 2.81, IC 95%: 1.54-5.12, p <0.05) y glucosa en ayunas alterada (OR 2.05, IC 95% 1.10 a 3.78, p <0.05) se asociaron significativamente con la presencia de nódulo tiroideo, independiente de la presencia de síndrome metabólico. El análisis multivariado mantuvo la asociación entre el síndrome metabólico y el nódulo tiroideo con un OR de 2.96 (IC 95% 1.47 a 5.95, p <0.05); de manera similar, las asociaciones de niveles bajos de HDL (OR 2.77, IC 95% 1.44 a 5.3, p <0.05) y glucosa en ayunas alterada (OR 2.23, IC 95% 1.14 a 4.34, p <0.05) con nódulo tiroideo permanecieron significativas. Conclusión: la enfermedad nodular tiroidea se asocia con un mayor riesgo de síndrome metabólico, específicamente la disminución de HDL y los niveles de glucosa en ayunas alterados fueron los factores que aumentaron la asociación.

Validation of methodology for assay, pharmaceutical equivalence, and comparative dissolution profile for tablets containing amlodipine besylate

The amlodipine besylate is indicated as a first choice in the treatment of hypertension. Many similar and generic drugproducts companies were able to bring out to the market dosage forms containing amlodipine besylate with lowerprices. In this context, the aim of this work was to validate a simple method for the determination of amlodipinecontent in tablets by ultraviolet spectrophotometry and to perform pharmaceutical equivalence and dissolution profilestudies for three similar and one generic drug products and their respective innovator tablet containing amlodipine(5 mg). The developed method for the determination of amlodipine content proved to be linear, precise, accurate,robust, and appropriate for employment in the quality control of tablets containing amlodipine besylate. The reference(R), similar (S1, S2, and S3), and generic (G) drug products all fulfilled the specifications for the tests of identification,average weight, hardness, friability, disintegration, drug content, content uniformity, and dissolution. However, incomparative dissolution profile studies, the dissolution efficiency of products G and S2 was statistically different fromproduct R, which may indirectly lead to the unsuitable bioavailability and therapeutic inefficacy. Thus, there is a needfor tighter legislation and inspection regarding the quality of pharmaceutical products already on the market.

Are acute infusion reactions after rituximab underreported?

Background: Rigorous premarketing trials may fail to capture safety issues associated with new drugs. This is more likely to happen in case of biopharmaceuticals. We take the case of rituximab, and anti CD20 monoclonal antibody, which was the first monoclonal antibody to get approval. This open label observational study was done with the objective of estimating the incidence of acute infusion reaction associated with rituximab infusion.Methods: The study population consisted of patients hospitalized for receiving rituximab, in day care centre(s) of a tertiary care hospital. Number and type of acute infusion reactions (AIR) were recorded on a case record form along with patient characteristics and medical history.Results: A total of 50 infusions were observed and all infusions were followed by at least one AIR. Total 71 AIRs were recorded among these 50 infusions (1.4 AIR per infusion). Non-Hodgkin’s lymphoma was the commonest indication for which patients were receiving rituximab. In a subset analysis, incidence of AIR was statistically lower in patients having received corticosteroids as premedication. However, brand of rituximab, gender of the patient and first or second cycle had no bearing on incidence of AIRs.Conclusions: AIRs are more common in real time clinical settings than what is reported. There is a need to formulate appropriate risk management plan depending on post marketing clinical data. Use of corticosteroids as premedication may be one such strategy. New drugs, esp biopharmaceuticals, may have unidentified/under reported safety issues and there is a need to undertake focussed pharmacovigilance endeavours to unravel them.

Efectos cardiovasculares de los nuevos fármacos no insulínicos en diabetes / Cardiovascular effects of new non-insulinic anti-diabetes drugs]

La diabetes mellitus constituye actualmente un grave problema de salud pública a nivel mundial, que incrementa el riesgo de presentar complicaciones tanto microvasculares como macrovasculares. Aunque lograr los objetivos de glucemia recomendados reduce el riesgo de complicaciones microvasculares, el efecto de los fármacos para tratar la hiperglucemia sobre las complicaciones macrovasculares y la muerte cardiovascular es motivo de preocupación. En este contexto, las agencias regulatorias han modificado la normativa para la aprobación de nuevos fármacos en diabetes, de forma que establecen la necesidad de demostrar que son capaces de disminuir la glucemia junto con una evaluación sólida de la seguridad cardiovascular. El objetivo de este trabajo es revisar los efectos cardiovasculares de las nuevas familias de fármacos no insulínicos, en especial en su efecto sobre el riesgo de eventos cardiovasculares mayores. En los últimos años, finalmente, se ha confirmado que algunos fármacos para tratar la diabetes no solo son seguros desde el punto de vista cardiovascular, sino que incluso han mostrado capacidad para reducir el riesgo de enfermedad cardiovascular en la diabetes mellitus tipo 2. La evidencia obtenida ha determinado la actualización de algunas guías terapéuticas vigentes cuando el riesgo cardiovascular debería considerarse una variable fundamental al momento de la elección terapéutica en pacientes con diabetes.

Diabetes mellitus is currently a serious public health problem worldwide, that increases the risk of presenting microvascular and macrovascular complications. Although achieving the recommended blood glucose goals reduces the risk of microvascular complications, the effect of the drugs used to treat hyperglycemia on macrovascular complications and cardiovascular death is a cause for concern. In this context, the regulatory agencies have modified the regulations for the approval of new drugs in diabetes, by adding the need to demonstrate that they are capable of lowering blood glucose levels together with a solid assessment of cardiovascular safety. The objective of this study is to review the cardiovascular effects of the new families of non-insulin drugs, with special emphasis on their effect on the risk of major cardiovascular events. In recent years, it has finally been confirmed that some of the drugs used to treat diabetes are not only safe from a cardiovascular point of view, but have even shown capacity to reduce the risk of cardiovascular disease in type 2 diabetes mellitus. The evidence obtained determined the updating of some current therapeutic guidelines when cardiovascular risk should be considered a fundamental variable at the time of therapeutic choice in patients with diabetes.
