Reuse of Treated Water from Municipal Treatment Plants in Mexico

Wastewater treatment plants (WWTPs) receive a wide variety of contaminants that cannot be eliminated or completely removed with current conventional methods. In this sense, the development and use of advanced technologies is a challenge in countries where wastewater sanitation is hardly a guarantee. However, the reuse of treated urban wastewater can function as an alternative to mitigate water pressure and, at the same time, guarantees water quality for potential reuse in agriculture, in the irrigation of landscape or urban green areas, but especially for aquifer recharge. Therefore, this chapter is focused on reviewing the current state of WWTPs in Mexico and the potential reuse of treated water

Image-guided brachytherapy in cervical cancer: Experience in the Complejo Hospitalario de Navarra

PurposeTo evaluate dosimetric and clinical findings of MRI-guided HDR brachytherapy (HDR-B) for cervical carcinoma.Material and methodsAll patients had a CT, MRI and pelvic-paraaortic lymphadenectomy. Treatment: pelvic (+/−)para-aortic3D/IMRT radiotherapy (45Gy), weekly cisplatin and HDR-B and pelvic node/parametrial boost 60Gy until interstitial brachytherapy was done. Two implants: 2008–2011: 5 fractions of 6Gy, 2011: 2016, 4 fractions of 7Gy. MRI/TAC were done in each implant. The following were defined: GTV, CTH-HR, CTV-IR; OAR: rectum, bladder and sigmoid.ResultsFrom 2007 to 2016: 57 patients. Patients: T1b2-T2a: 4p, T2b 41p, T3a: 2p; T3B 8p T4a: 2p; N0: 32p, N1 21p, no lymphadenectomy: 4p. Median follow up: 74.6m (16–122m), recurrence: 5p local, 6p node, 9p metastasis and 37p without recurrence.Local control 5 years: 90.1%; Ib2-IIB: 94.8%, III-IVa: 72.2%. (p:0.01). RDFS 5y was 92.5%; IB2-IIB: 93%, III: 85% (p:0.024); for pN0: 100%; pN+ iliac-paraaortic: 71.4% (p: 0.007). MFS 5y was 84.1%. Overall survival (OS) at 5y: 66.6% and the cancer specific survival (CEOS) was 74%. Univariate analysis survival: stage Ib2-II 83% vs. III-IVa 41% (p=0.001); histology: squamous 78%, adenocarcinoma 59.7% (p: ns); lymph node: N0 85% vs. PA+P− 72%, and PA+P+ 35% (p=0.010). In relation with: HR-CTV dose>85Gy, CEOS: 82.5% vs. 77%, and volume CTV-HR30 cc: 67%; p: ns. Acute grade 2–3 toxicity: rectal 15.7%, intestinal 15.7% and vesical 15.5%.ConclusionUse of interstitial HDR-BQ guided by RM increased CTV-HR dose and local control, like EMBRACE results. Nodal boost improves RDFS and perhaps OS

Reproducibility and validity of a food frequency questionnaire among pregnant women in a Mediterranean area

Background: Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against biochemical biomarkers) of a semi-quantitative food frequency questionnaire (FFQ) in pregnant women. Methods: Participants were 740 pregnant women from a population-based birth cohort study in Valencia (INMA Study). We compared nutrient and food intakes from FFQs estimated for two periods of pregnancy (reproducibility), and compared energy-adjusted intake of several carotenoids, folate, vitamin B12, vitamin C and α-tocopherol of the FFQ in the first trimester with their concentration in blood specimens (validity). Results: Significant correlations for reproducibility were found for major food groups and nutrients but not for lycopene (r=0.06); the average correlation coefficients for daily intake were 0.51 for food groups and 0.61 for nutrients. For validity, statistically significant correlations were observed for vitamin C (0.18), α-carotene (0.32), β-carotene (0.22), lutein-zeaxantin (0.29) and β-cryptoxantin(0.26); non-significant correlations were observed for retinol, lycopene, α-tocopherol, vitamin B12 and folate (r≤0.12). When dietary supplement use was considered, correlations were substantially improved for folate (0.53) and to a lesser extent for vitamin B12 (0.12) and vitamin C (0.20). Conclusion: This study supports that the FFQ has a good reproducibility for nutrient and food intake, and can provide a valid estimate of several important nutrients during pregnanc

Hidrocoloides extraídos de Opuntia robusta y su actividad antioxidante

El mercado de los hidrocoloides experimenta una creciente demanda de productos competitivos con características especiales para su aplicación en diferentes áreas, como el sector alimentario y farmacéutico, la utilidad e importancia de los hidrocoloides se fundamentan en sus propiedades funcionales como la estabilización, el espesamiento y la gelificación, además de las nutriceas. En este trabajo se propone el uso de pectina proveniente de una fuente no explotada, la Opuntia robusta, que es una fruta de nopal silvestre, conocida comúnmente como tuna tapona; considerado como un residuo agroalimentario, por su tamaño, contenido de semillas y espinas, no es competitiva con la de tipo comercial. Se evaluaron algunas propiedades fisicoquímicas y su actividad antioxidante in vitro y fenoles totales. Los resultados sugieren que la pectina obtenida de Opuntia robusta puede emplearse como aditivo para mejorar las propiedades de viscosidad y textura, además con actividad antioxidante.The hydrocolloid market experiences a growing demand for competitive products with special characteristics for application in different areas, such as the food and pharmaceutical sector, the usefulness and importance of hydrocolloids are based on their functional properties such as stabilization, thickening and gelation, in addition to the nutriceas. The use of pectin from an untapped source, Opuntia robusta, is proposed, as it is a wild nopal fruit, commonly known as tuna tapona; considered as an agri-food waste, since due to its size, content of seeds and thorns, it is not competitive with that of a commercial type, some physicochemical properties and antioxidant activity in vitro and total phenols were evaluated. The results suggest that the pectin obtained from Opuntia robusta can be used as an additive to improve viscosity and texture properties, in addition to antioxidant activity

Respiratory viruses detected in Mexican children younger than 5 years old with community-acquired pneumonia: a national multicenter study

Background: Acute respiratory infections are the leading cause of mortality in children worldwide, especially in developing countries. Pneumonia accounts for 16% of all deaths of children under 5 years of age and was the cause of death of 935 000 children in 2015. Despite its frequency and severity, information regarding its etiology is limited. The aim of this study was to identify respiratory viruses associated with community-acquired pneumonia (CAP) in children younger than 5 years old. Methods: One thousand four hundred and four children younger than 5 years of age with a clinical and/or radiological diagnosis of CAP in 11 hospitals in Mexico were included. Nasal washes were collected, placed in viral medium, and frozen at �70 C until processing. The first 832 samples were processed using the multiplex Bio-Plex/Luminex system and the remaining 572 samples using the Anyplex multiplex RT-PCR. Clinical data regarding diagnosis, clinical signs and symptoms, radiographic pattern, and risk factors were obtained and recorded. Results: Of the samples tested, 81.6% were positive for viruses. Respiratory syncytial virus (types A and B) was found in 23.7%, human enterovirus/rhinovirus in 16.6%, metapneumovirus in 5.7%, parainfluenza virus (types 1–4) in 5.5%, influenza virus (types A and B) in 3.6%, adenovirus in 2.2%, coronavirus (NL63, OC43, 229E, and HKU1) in 2.2%, and bocavirus in 0.4%. Co-infection with two or more viruses was present in 22.1%; 18.4% of the samples were negative. Using biomass for cooking, daycare attendance, absence of breastfeeding, and co-infections were found to be statistically significant risk factors for the presence of severe pneumonia. Conclusions: Respiratory syncytial virus (types A and B), human enterovirus/rhinovirus, and metapneumovirus were the respiratory viruses identified most frequently in children younger than 5 years old with CAP. Co-infection was present in an important proportion of the children
