A real-life study of the medium to long-term effectiveness of a hypercaloric, hyperproteic enteral nutrition formula specifically for patients with diabetes on biochemical parameters of metabolic control and nutritional status.

INTRODUCTION: Although current recommendations suggest the use of specific formulas in enteral nutrition in people with diabetes, there is little evidence of their long-term effectiveness in glycemic control. The main objective of this study is to evaluate the long-term efficacy (24 weeks) of a specific high-protein hypercaloric enteral nutrition formula for people with diabetes in glycemic control and in their improvement in nutritional status. METHODOLOGY: This was a multicenter, prospective, observational, real-life study of patients with long-term enteral nutrition prescription through gastrostomy or nasogastric tube who received a high protein hypercaloric formula specific for diabetes. Once the participant's informed consent was obtained and the inclusion and exclusion criteria were verified, data relating to glycemic control, inflammation parameters, biochemical data, nutritional status and gastrointestinal tolerance at 0, 12 and 24 weeks were collected. RESULTS: 112 patients were recruited, 44.6% women, age 75.0 (12.0) years and a mean time of evolution of diabetes of 18.1 (9.5) years. The percentage of patients with malnutrition according to VGS decreased throughout the treatment from 78.6% to 29.9% (p < 0.001). Glycemic and HbA1c levels were significantly reduced at 12 and 24 weeks (Blood glucose 155.9-139.0-133.9 mg/dl, p < 0.001; HbA1c 7.7-7.3-7.1%, p < 0.001) while no significant changes were observed in cholesterol, triglycerides, creatinine, or glomerular filtration. A significant increase in variables related to nutritional status was observed: weight, the BMI, albumin, prealbumin and transferrin, and CRP levels were significantly reduced and the CRP/Albumin ratio decreased. Gastrointestinal tolerance was good, the number of patients with moderate-severe symptoms was small, and did not change throughout the follow-up. CONCLUSION: Our real-life study suggests that the use of a specific hyperprotein hypercaloric formula for diabetes during a 6-month nutritional treatment allows adequate glycemic control and nutritional evolution, with good gastrointestinal tolerance.

Prospective comparative multi-centre study on imported Plasmodium ovale wallikeri and Plasmodium ovale curtisi infections.

BACKGROUND: Few previous retrospective studies suggest that Plasmodium ovale wallikeri seems to have a longer latency period and produces deeper thrombocytopaenia than Plasmodium ovale curtisi. Prospective studies were warranted to better assess interspecies differences. METHODS: Patients with imported P. ovale spp. infection diagnosed by thick or thin film, rapid diagnostic test (RDT) or polymerase chain reaction (PCR) were recruited between March 2014 and May 2017. All were confirmed by DNA isolation and classified as P. o. curtisi or P. o. wallikeri using partial sequencing of the ssrRNA gene. Epidemiological, analytical and clinical differences were analysed by statistical methods. RESULTS: A total of 79 samples (35 P. o. curtisi and 44 P. o. wallikeri) were correctly genotyped. Males predominate in wallikeri group (72.7%), whereas were 48.6% in curtisi group. Conversely, 74.3% of curtisi group were from patients of African ethnicity, whilst 52.3% of Caucasians were infected by P. o. wallikeri. After performing a multivariate analysis, more thrombocytopaenic patients (p = 0.022), a lower number of platelets (p = 0.015), a higher INR value (p = 0.041), and shorter latency in Caucasians (p = 0.034) were significantly seen in P. o. wallikeri. RDT sensitivity was 26.1% in P. o. curtisi and 42.4% in P. o. wallikeri. Nearly 20% of both species were diagnosed only by PCR. Total bilirubin over 3 mg/dL was found in three wallikeri cases. Two patients with curtisi infection had haemoglobin under 7 g/dL, one of them also with icterus. A wallikeri patient suffered from haemophagocytosis. Chemoprophylaxis failed in 14.8% and 35% of curtisi and wallikeri patients, respectively. All treated patients with various anti-malarials which included artesunate recovered. Diabetes mellitus was described in 5 patients (6.32%), 4 patients of wallikeri group and 1 curtisi. CONCLUSIONS: Imported P. o. wallikeri infection may be more frequent in males and Caucasians. Malaria caused by P. o. wallikeri produces more thrombocytopaenia, a higher INR and shorter latency in Caucasians and suggests a more pathogenic species. Severe cases can be seen in both species. Chemoprophylaxis seems less effective in P. ovale spp. infection than in P. falciparum, but any anti-malarial drug is effective as initial treatment. Diabetes mellitus could be a risk factor for P. ovale spp. infection.

Diferencias epidemiológicas, clínico-microbiológicas y terapéuticas de la enfermedad tuberculosa en pacientes con infección por VIH y sin ella / Epidemiological, clinical, microbiological and therapeutic differences in tuberculosis disease in patients with and without HIV infection

Introducción y objetivo: Nuestro objetivo es analizar la incidencia de tuberculosis (TB) en nuestra población y comparar las características de los pacientes con y sin infección por VIH (I-VIH). Pacientes y métodos: Estudio clínico-epidemiológico de cohortes retrospectivo. Se incluyeron pacientes diagnosticados de TB con y sin I-VIH entre los años 2005-2016 en la provincia de Guadalajara (España). Se analizaron variables epidemiológicas, clínicas, microbiológicas y terapéuticas, incluyendo las resistencias microbiológicas. Resultados: Se realizaron 261 diagnósticos de TB. Hubo 25 pacientes (9,6%) que presentaban I-VIH, los cuales eran predominantemente varones, tenían una mayor incidencia de virus de la hepatitis C, mayor porcentaje de afectación extrapulmonar, una mayor prevalencia de resistencia a la isoniacida y a la rifampicina así como una mayor respuesta paradójica y estancia media más prolongada. Por otra parte, presentaron menor porcentaje de prueba de tuberculina positiva y de baciloscopias en esputo positivas. Un porcentaje significativo de pacientes con TB no tenían realizada una serología para VIH. Conclusión: Los pacientes con I-VIH muestran notables diferencias en variables epidemiológicas, clínicas y de resistencia a los fármacos antituberculosos. En un porcentaje elevado de pacientes con TB se desconoce su serología para VIH

Background and objective: Our objective is to analyze the incidence of tuberculosis (TB) in our population and to compare the characteristics of patients with and without HIV infection. Patients and methods: Clinical-epidemiological retrospective cohort study that included patients diagnosed with TB with and without HIV infection between 2005-2016 in the province of Guadalajara (Spain). Epidemiological, clinical, microbiological and therapeutic variables were assessed, including microbiological resistances. Results: TB was diagnosed in 261 patients.

Travelers' Diarrhea in Children at Risk: An Observational Study From a Spanish Database.

BACKGROUND: Gastrointestinal symptoms are a common cause of consultation about children traveling to or coming from developing countries. The aim of this study was to identify the risk factors associated with gastrointestinal syndrome in children who travel. METHODS: A prospective observational analytical and multicenter study was performed within +Redivi, a Spanish Tropical Medicine network on imported infections, from January 2009 to December 2013. All participants aged 16 years and younger were included in the analysis. Ethical approval was obtained from all the participating centers. RESULTS: A total of 606 children ≤16 years of age were registered in the +Redivi database during the study period. Median age was 8.7 years (interquartile range, 4.4-12.4 years), 65.8% (399/606) were immigrants, 90% were >2 years old and 54% were male. Median travel duration, excluding immigrants, was 50 days (interquartile range, 30-150 days). Children with gastrointestinal symptoms represented 13.5% (82/606) of total consultations. A significant association was found in bivariate analysis between gastrointestinal disorder and age <2 years (P < 0.01) and travel duration (P = 0.046). Immigrants had less gastrointestinal disorders than tourists (P < 0.05). The most prevalent infection was protozoan in 23.4% (142/606), and Giardia intestinalis was the most common pathogen in 10.1% (61/606) of total children. Independent risk factors for gastrointestinal symptoms were tourist and traveler child visiting friends and relatives (P = 0.03), travel duration <90 days (P = 0.008) and bacterial cause (P < 0.001). CONCLUSIONS: Traveling children who developed a gastrointestinal syndrome represented 13.5% of the total pediatric consultations in +Redivi. Independent risk factors were tourist or traveler visiting friends and relatives, travel duration <90 days and bacterial infection. G. intestinalis was the most common infectious agent causing a gastrointestinal disorder in the traveler children.

Characteristics of HIV infected individuals traveling abroad. Results from the +REDIVI Collaborative Network / Características de los individuos infectados por el VIH que viajan al extranjero. Los resultados de la red +REDIVI

INTRODUCTION: The improvement in the prognosis of HIV infection, coupled with the increase in international travel and migration, has led to a rising number of HIV infected travelers. The objective of this study was to describe the epidemiological and clinical features of returning travelers, according to their HIV status. METHODS: An observational prospective study was conducted including travelers and immigrants who traveled to visit friends and relatives (VFRs) registered in the +REDIVI collaborative network (January-2009; October-2014). +REDIVI is a national network that registers information regarding infections imported by travelers and immigrants at 21 different centers using a standardized protocol. RESULTS: A total of 3464 travellers were identified: 72 were HIV+ (2.1%) and 3.392 HIV− (98%). HIV+ vs. HIV− travelers were often older (40.5y vs. 34.2y P = .001), VFRs (79.1% vs. 44.4%; P < .001), and consulted less for pre-travel advice (27% vs. 37%; P = .078). The main destinations for both groups were sub-Saharan Africa and Latin America. The most frequent reasons for consultation after travel were fever, request for a health examination, gastrointestinal complaints, and abnormal laboratory tests (mainly eosinophilia and anemia), which differed between groups. The most frequent diagnoses in HIV+ travelers were malaria (38.8%), newly diagnosed HIV infection (25%), and intestinal parasites (19.4%), while for HIV− travelers the main diagnoses were "healthy" (17.9%), malaria (14%), and intestinal parasites (17.3%). CONCLUSIONS: The typical profile of an HIV+ traveler in +REDIVI was that of a VFR traveler who did not seek pre-travel advice and made high-risk trips. This may increase the chance of acquiring travel-related infections which may pose a special risk for HIV-infected travelers. The post-travel visit was a good opportunity for HIV infection screening

INTRODUCCIÓN: La mejoría en el pronóstico de la infección por el VIH, sumada al incremento de los viajes y la inmigración, han aumentado la frecuencia del binomio viajero-VIH+. El objetivo de este trabajo es describir la epidemiología y hallazgos clínicos de los viajeros VIH+ en comparación con los VIH-. MÉTODOS: Estudio observacional y prospectivo, de los viajeros e inmigrantes viajeros que se desplazan para visitar familiares y amigos (VFR) incluidos en la red +REDIVI (enero-2009; octubre-2014). +REDIVI es una red nacional que recopila información sobre infecciones importadas por viajeros e inmigrantes en 21 centros mediante un protocolo estandarizado de recogida de datos. RESULTADOS: Se identificaron 3.464 viajeros: 72 VIH+ (2,1%) y 3.392 VIH− (98%). Los VIH+ en contraste con los VIH−, eran mayores (40 vs. 34 años; p = 0,001), predominantemente VFR (79,7% vs 44,4%. p < 0,001), y solicitan menos consejo pre-viaje (27% vs 37%. p = 0,078). Los destinos predominantes para ambos grupos fueron África Subsahariana y Latinoamérica. Los motivos de consulta más frecuentes al retorno del viaje fueron la fiebre, solicitar un examen de salud, molestias gastrointestinales, y anomalías en los resultados de laboratorio (principalmente eosinofilia y anemia) los cuales variaron según el grupo. Los diagnósticos más frecuentes en los VIH+ fueron la malaria (38,8%), nuevo diagnóstico de VIH (25%) y parasitosis intestinales (19,4%), mientras que en los sujetos VIH− los principales diagnósticos fueron "sano" (17,9%), parásitos intestinales (17,3%) y malaria (14%). CONCLUSIONES: El perfil más común del viajero VIH+ atendido en +Redivi es el de un inmigrante VFR que no solicita consejo pre-viaje y hace viajes de alto riesgo. Esto puede suponer un mayor riesgo de adquisición de infecciones relacionadas con el viaje, las cuales en un viajero VIH+ pueden tener un efecto deletéreo adicional. La consulta tras el viaje es una buena oportunidad para el cribado de la infección por VIH
