RESUMO

Purpose: Despite newer type 2 diabetes (T2D) medications, patients do not always achieve metabolic targets, remaining at risk for cardiorenal complications. Therapeutic decisions are generally made by the healthcare team without considering patients' preferences. We aimed to evaluate patients' T2D treatment preference in two Latin-American countries between two different oral medication profiles, one resembling dipeptidyl peptidase-4 inhibitors (DPP4i) and another resembling sodium-glucose cotransporter-2 inhibitors (SGLT2i). Patients and Methods: In this cross-sectional, multicenter study from June to September 2020, patients with T2D from Argentina and Mexico (n = 390) completed a discrete choice experiment questionnaire to identify preferences between DPP4i (medication profile A) and SGLT2i (medication profile B). The reason behind patients' choice, and the association between their baseline characteristics and their preference were evaluated using logistic regression methods. Results: Most participants (88.2%) preferred SGLT2i's profile. Participants with older age (p = 0.0346), overweight or obesity (p < 0.0001), high blood pressure (BP; p < 0.0001), high total cholesterol (p = 0.0360), and glycosylated hemoglobin (HbA1c) <7% (p = 0.0001) were more likely to choose SGLT2i compared with DPP4i's profile. The most and least important reasons to choose either drug profile were HbA1c reduction and genital infection risk, respectively. The likelihood of selecting the SGLT2i's profile significantly increased in participants with increased body mass index (BMI; odds ratio [OR] = 8.9, 95% confidence interval [CI]: 3.5-22.5, p < 0.05), high BP (OR = 4.9, 95% CI: 1.9-12.4, p < 0.05), and lower education level (OR = 3.6, 95% CI: 1.0-12.6, p < 0.05). Conclusion: Latin-American patients with T2D preferred medication with a profile resembling SGLT2i over one resembling DPP4i as a treatment option. A patient-centered approach may aid the healthcare team in decision-making for improved outcomes.

RESUMO

Alterations in eating behavior characterized eating disorders (ED). The genetic factors shared between ED diagnoses have been underexplored. The present study performed a genome-wide association study in individuals with disordered eating behaviors in the Mexican population, blood methylation quantitative trait loci (blood-meQTL), summary data-based Mendelian randomization (SMR) analysis, and in silico function prediction by different algorithms. The analysis included a total of 1803 individuals. We performed a genome-wide association study and blood-meQTL analysis by logistic and linear regression. In addition, we analyzed in silico functional variant prediction, phenome-wide, and multi-tissue expression quantitative trait loci. The genome-wide association study identified 44 single-nucleotide polymorphisms (SNP) associated at a nominal value and seven blood-meQTL at a genome-wide threshold. The SNPs show enrichment in genome-wide associations of the metabolic and immunologic domains. In the in silico analysis, the SNP rs10419198 (p-value = 4.85 × 10-5) located on an enhancer mark could change the expression of PRR12 in blood, adipocytes, and brain areas that regulate food intake. Additionally, we found an association of DNA methylation levels of SETBP1 (p-value = 6.76 × 10-4) and SEMG1 (p-value = 5.73 × 10-4) by SMR analysis. The present study supports the previous associations of genetic variation in the metabolic domain with ED.

RESUMO

Herein we describe a new species, Tillancoccus koreguajae Caballero & Ramos, sp. n. (Hemiptera: Coccidae) from Colombia collected on sugarcane. Pinnaspis strachani (Cooley) is also recorded on sugarcane for the first time worldwide. An updated list of seven species of Coccomorpha on sugarcane in Colombia is provided, including information on its distribution, biology, and mutualistic ants for each species. Seven species of scale insects (Hemiptera: Coccomorpha) have been recorded previously on sugarcane, Saccharum officinarum L. (Poaceae) in Colombia: Pseudococcidae: Dysmicoccus boninsis (Kuwana), D. brevipes (Cockerell), Pseudococcus calceolariae (Maskell), Saccharicoccus sacchari (Cockerell); Coccidae: Pulvinaria elongata Newstead; Diaspididae: Duplachionaspis divergens (Green) and Serenaspis minima (Maskell). However, the record of S. minima in Colombia is considered doubtful as there are no voucher specimens from Colombia and because the distribution of this species is currently limited to the Australasian region. Pseudococcus calceolariae is present in Colombia but its record on sugarcane is also doubtful. A taxonomic key for the identification of scale insects on sugarcane in Colombia is provided.

RESUMO

OBJECTIVE: To explore the association of three polymorphisms of the serotonin receptor 1Dß gene (HTR1B) in the etiology of eating disorders and their relationship with clinical characteristics. METHODS: We analyzed the G861C, A-161T, and A1180G polymorphisms of the HTR1B gene through a family-based association test (FBAT) in 245 nuclear families. The sample was stratified into anorexia nervosa (AN) spectrum and bulimia nervosa (BN) spectrum. In addition, we performed a quantitative FBAT analysis of anxiety severity, depression severity, and Yale-Brown-Cornell Eating Disorders Scale (YBC-EDS) in the AN and BN-spectrum groups. RESULTS: FBAT analysis of the A-161T polymorphism found preferential transmission of allele A-161 in the overall sample. This association was stronger when the sample was stratified by spectrums, showing transmission disequilibrium between the A-161 allele and BN spectrum (z = 2.871, p = 0.004). Quantitative trait analysis showed an association between severity of anxiety symptoms and the C861 allele in AN-spectrum participants (z = 2.871, p = 0.004). We found no associations on analysis of depression severity or preoccupation and ritual scores in AN or BN-spectrum participants. CONCLUSIONS: Our preliminary findings suggest a role of the HTR1B gene in susceptibility to development of BN subtypes. Furthermore, this gene might have an impact on the severity of anxiety in AN-spectrum patients.

RESUMO

INTRODUCTION: The morbid obesity (BMI greater than or equal to 40 kg/m2) is associated with dysfunction of the hypothalamus-pituitary-thyroid axis, showing high levels of thyrotropin (TSH), triiodothyronine (T3) total and free, suspecting a real thyroid condition. Our objetive was to describe the alterations in thyroid function in patients with morbid obesity, determining serum levels of TSH, total T3, free T4 and thyroid peroxidase antibodies (TPO). METHODS: Prospective, descriptive, observational, cross-sectional study, we enrolled 52 patients with morbid obesity, at the obesity clinic, from department of Endocrinology, since January 2009 to July 2011. All patients signed a letter of informed consent. Patients with known thyroid disorders and/or under the use of levothyroxine or other medication that causes alteration in thyroid function were excluded. Statistical analysis was performed using measures of central tendency, simple frequencies, percentages and Spearman's correlation. RESULTS: The prevalence of primary hypothyroidism was 8%, 6% subclinical hypothyroidism and thyroid function alterations secondary to obesity of 23% (elevated TSH and/or free T4 Total T3 with normal and TPO antibody negative). CONCLUSIONS: Most morbidly obese patients haven't autoimmune thyroid dysfunction; the alterations in thyroid function are caused by an effect of homeostasis against obesity and can be corrected by reducing weight.

Introducción: La obesidad mórbida (IMC greater than or equal to 40 kg/m2) se asocia con disfunción del eje hipotálamo-hipófisis- tiroides, presentando elevación de tirotropina (TSH), de la triyodotironina (T3) total y libre, sospechando de una auténtica afección tiroidea. El objetivo fue describir las alteraciones en la función tiroidea en pacientes con obesidad mórbida, determinando niveles séricos de TSH, T3 total, T4 libre y anticuerpos antiperoxidasa (TPO).Métodos: estudio prospectivo, descriptivo, observacional y transversal, incluyó 52 pacientes con obesidad mórbida de la clínica de obesidad del departamento de Endocrinología, de enero del 2009 a julio del 2011. Se excluyeron pacientes con alteraciones tiroideas conocidas y/o bajo el uso de levotiroxina u otro medicamento que cause alteración en el perfil tiroideo. El análisis estadístico se realizó con medidas de tendencia central, frecuencias simples, porcentajes y se realizó correlación de Spearman.Resultados: la prevalencia de hipotiroidismo primario fue de 8 %, hipotiroidismo subclínico en 6 % y las alteraciones en el perfil tiroideo secundarias a obesidad del 23 % (elevación de TSH y/o T3 total con T4 libre normal y anticuerpos TPO negativos).Conclusiones: la mayoría de los pacientes con obesidad mórbida no presentan disfunción tiroidea autoinmune, las alteraciones en el perfil tiroideo son causadas por un efecto de homeostasis frente a la obesidad y pueden ser corregidas al disminuir de peso.
