Prevalence and risk factors of gestational diabetes mellitus: findings from a universal screening feasibility program in Lima, Peru.

BACKGROUND: Gestational diabetes mellitus (GDM) is a global public health concern with potential implications for the health of a mother and her offspring. However, data on the prevalence and risk factors of GDM in Latin America are scarce. The study was designed to estimate the prevalence of GDM and identify maternal risk factors among Peruvian women. METHODS: A cross-sectional study was conducted among 1300 pregnant women attending a prenatal clinic in Lima, Peru. GDM was diagnosed using an Oral Glucose Tolerance Test (OGTT) performed between 24 and 28 gestational weeks using the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. Depression status was assessed using the Patient Health Questionnaire-9. Multivariate logistic regression models were used to identify risk factors of GDM. RESULTS: Approximately 16% of pregnant women were diagnosed with GDM. The prevalence of obesity and depression were 24.4 and 10.6%, respectively. After adjusting for confounders, mid-pregnancy obesity was associated with a 1.64-fold increased odds of GDM (OR: 1.64; 95% CI: 1.03-2.61). Participants with a family history of diabetes had a 1.5-fold increased odds of developing GDM (OR: 1.51, 95% CI: 1.10-2.07) as compared to women without this family history. Depression was associated with a 1.54-fold increased odds of GDM (OR: 1.54; 95% CI:1.09-2.17). CONCLUSIONS: GDM is highly prevalent and was associated with maternal obesity, family history of diabetes and antepartum depression among Peruvian women. Intervention programs aimed at early diagnoses and management of GDM need to take maternal obesity, family history of diabetes and antepartum depression into account.

Comparison of FDA-Approved Electrical Neuromodulation Techniques for Focal Neuropathic Pain: A Narrative Review of DRG, HF10, and Burst Neuromodulation.

BACKGROUND: Evidence suggests that dorsal root ganglion stimulation (DRGS) is a more effective treatment for focal neuropathic pain (FNP) compared with tonic, paresthesia-based dorsal column spinal cord stimulation (SCS). However, new advancements in waveforms for dorsal column SCS have not been thoroughly studied or compared with DRGS for the treatment of FNP. OBJECTIVES: The purpose of this review was to examine the evidence for these novel technologies; to highlight the lack of high-quality evidence for the use of neuromodulation to treat FNP syndromes other than complex regional pain syndrome I or II of the lower extremity; to emphasize the absence of comparison studies between DRGS, burst SCS, and high-frequency SCS; and to underscore that consideration of all neuromodulation systems is more patient-centric than a one-size-fits-all approach. STUDY DESIGN: This is a review article summarizing case reports, case series, retrospective studies, prospective studies, and review articles. SETTING: The University of Miami, Florida. METHODS: A literature search was conducted from February to March 2020 using the PubMed and EMBASE databases and keywords related to DRGS, burst SCS, HF10 (high-frequency of 10 kHz), and FNP syndromes. All English-based literature from 2010 reporting clinical data in human patients were included. RESULTS: Data for the treatment of FNP using burst SCS and HF10 SCS are limited (n = 11 for burst SCS and n = 11 for HF10 SCS). The majority of these studies were small, single-center, nonrandomized, noncontrolled, retrospective case series and case reports with short follow-up duration. To date, there are only 2 randomized controlled trials for burst and HF10 for the treatment of FNP. LIMITATIONS: No studies were available comparing DRGS to HF10 or burst for the treatment of FNP. Data for the treatment of FNP using HF10 and burst stimulation were limited to a small sample size reported in mostly case reports and case series. CONCLUSIONS: FNP is a complex disease, and familiarity with all available systems allows the greatest chance of success.

Genetic markers for preeclampsia in Peruvian women.

BACKGROUND: Preeclampsia is a multiorgan disorder associated with maternal and perinatal morbi-mortality. In Peru, incidence is 10% and accounts for 22% of maternal deaths. Genome and genetic epidemiological studies have found an association between preeclampsia and genetic polymorphisms. OBJECTIVE: To determine the association of the vascular endothelial growth factor (VEGF) +936 C/T and +405 G/C, interleukine-6 (IL-6) -174 G/C, IL-1ß-511 C/T, Apo A-1-75 G/A, Apo B-100 2488 C/T (Xbal) polymorphisms with preeclampsia in pregnant Peruvian women. METHODS: Were included preeclamptic and healthy (control) pregnant women. Maternal blood samples were subjected to DNA extraction, and molecular genetic analysis was conducted using the PCR-RFLP technique and following a specific protocol for each gene. Allele and genotypic frequencies in the cases and controls were compared. RESULTS: No association was found between the VEGF+936C/T and VEGF+405 polymorphisms and preeclampsia. The frequencies of the GG genotypes and the G allele of the -174 G/C polymorphism in the IL6 gene in preeclamptic and controls showed significant differences, with higher frequencies in cases. For the -511 C/T polymorphism of the IL-1ß gene, no significant differences were found in the frequencies of TT genotypes compared with CT+CC. The genotypes and alleles of the Apo-A1-75 G/A and Apo-B100 Xbal variants showed no significant differences between cases and controls. CONCLUSION: No association was found between the studied genetic markers and preeclampsia. However, in the -174G/C polymorphism of the IL-6 gene, significant differences were found mainly in the GG genotype and G allele.

Resumen Antecedentes: La preeclampsia es un trastorno multiorgánico asociado con la morbi-mortalidad materna y perinatal. En el Perú, su incidencia es del 10% y causa el 22% de las muertes maternas. Se encontró una asociación entre la preeclampsia y ciertos polimorfismos. Objetivo: Determinar asociación entre los polimorfismos genéticos del factor de crecimiento endotelial vascular (VEGF) +936 C/T y +405 G/C, interleucina-6 (IL-6) -174G/C, IL-1β -511 C/T, Apo A-1 -75 G/A, Apo B-100 2488 C/T (Xbal), y preeclampsia en gestantes peruanas. Métodos: Se incluyeron gestantes preeclámpticas y sanas (controles). Las muestras de sangre fueron procesadas para extracción del ADN, y el análisis se realizó con la técnica PCR-RFLP con protocolos específicos para cada gen y confirmación con secuenciamiento Sanger. Se compararon las frecuencias alélicas y genotípicas en los casos (preeclampsia) y los controles. Resultados: No se halló asociación entre los polimorfismos VEGF+936-C/T y VEGF+405 y la preeclampsia. Las frecuencias de los genotipos GG y el alelo G del polimorfismo -174-G/C en el gen IL6 en preeclámpticas y controles, mostraron diferencias significativas, con frecuencias más altas en los casos. Para el polimorfismo -511-C/T del gen IL-1β, no se encontraron diferencias significativas en las frecuencias de genotipos TT comparados con CT+CC. Los genotipos y alelos de las variantes Apo-A1-75-G/A y Apo-B100 Xbal no mostraron diferencias significativas entre los grupos Conclusión: No se encontró asociación entre los marcadores genéticos estudiados y la preeclampsia. Sin embargo, el polimorfismo -174-G/C en el gen IL6 mostró diferencias significativas principalmente en el genotipo GG y el alelo G.

Costos de la atención postaborto en hospital es de Lima, Perú

Objetivos: Determinar el costo de atención de los abortos incompletos en los hospitales públicos y de abortos electivos en una institución privada. Diseño: Investigación prospectiva. Participantes: Mujeres con aborto incompleto. Metodología: En 120 mujeres con aborto incompleto complicado o no complicado en cuatro hospitales públicos de Lima y 40 mujeres en una clínica privada, se estableció el tiempo que demandó la atención, costo de personal, medicamentos, insumos, equipos y funcionamiento del hospital; igualmente el costo de bolsillo, transporte, cuidado de los niños y del hogar y el ingreso dejado de percibir. Todas firmaron un consentimiento informado. Principales medidas de resultados: Costos de atención. Resultados: La permanencia en tres hospitales, hasta el alta, por aborto incompleto no complicado fue alrededor de 6 horas, siendo mayor en uno de ellos por la normativa interna. En los cuatro hospitales, las complicaciones del aborto ameritaron una permanencia mayor. Las mujeres de aborto electivo requirieron la mitad del tiempo de aquellas con aborto incompleto no complicado en los hospitales. El costo total para la atención de abortos incompletos no complicados fue similar en los cuatro hospitales, entre US$ 110 y US$ 150; y para abortos complicados varió entre US$ 376 y US$ 858. El costo total de atención de los abortos electivos fue similar a la atención del aborto no complicado en los hospitales. Conclusiones: La permanencia de las mujeres con aborto no complicado fue relativamente corta en los hospitales. El costo de atención de los abortos complicados y no complicados demandó un monto importante para los hospitales y las propias mujeres. Los costos del aborto electivo estuvieron al alcance de las mujeres y ninguno de ellos evidenció complicación alguna.

Objectives: To determine care costs of incomplete abortions at public hospitals and elective abortions at a private institution. Design: Prospective study. Participants: Women with incomplete abortion. Methods: In 120 women with either complicated or non-complicated incomplete abortion in four public hospitals and 40 women in a private hospital, time for attention, cost of personal, drugs, materials, equipments and hospital functioning were determined; also pocket cost, transportation, children and home care and non-perceived income. All women signed informed consent. Main outcome measures: Care costs. Results: Hospital stay at three hospitals for non-complicated incomplete abortion until discharge was about 6 hours, more in one hospital because of internal norms. Abortion complications at the four hospitals required longer stay. Women with elective abortion required half the time of those with non-complicated incomplete abortion at hospitals. Total cost for non-complicated incomplete abortions care was similar at the four hospitals, between US$ 110 and US$ 150, and for complicated abortions between US$ 376 and US$ 858. Elective abortions care total cost was similar to that of non-complicated abortions care at hospitals. Conclusions: Non-complicated abortion stay of women was relatively short at hospitals. Complicated and non-complicated abortions care demanded an important cost for hospitals and women themselves. Elective abortion costs were accesible to every woman and none had complications.
