Abstract
The dynamic interactions between dissolved organic matter (DOM) and particulate organic matter (POM) are central in nutrient cycling in freshwater ecosystems. However, the molecular-level mechanisms of such interactions are still poorly defined. Here, we study spatial differences in the chemical and molecular composition of suspended sediments in the River Chew, UK. We then applied a compound-specific stable isotope probing (SIP) approach to test the potential assimilation of 13C,15N-glutamate (Glu) and 15N-nitrate into proteinaceous biomass by particle-associated microbial communities over a 72-h period. Our results demonstrate that the composition of suspended sediments is strongly influenced by the effluent of sewage treatment works (STW). Fluxes and percentages of assimilation of both isotopically labelled substrates into individual proteinaceous amino acids (AAs) showed contrasting dynamics in processing at each site linked to primary biosynthetic metabolic pathways. Preferential assimilation of the organic molecule glutamate and evidence of its direct assimilation into newly synthesised biomass was obtained. Our approach provides quantitative molecular information on the mechanisms by which low molecular weight DOM is mineralised in the water column compared to an inorganic substrate. This is paramount for better understanding the processing and fate of organic matter in aquatic ecosystems.

Abstract
Background

Previous studies have explored using calibrated low-cost particulate matter (PM) sensors, but important research gaps remain regarding long-term performance and reliability.
Objective

Evaluate longitudinal performance of low-cost particle sensors by measuring sensor performance changes over 2 years of use.
Methods

51 low-cost particle sensors (Airbeam 1 N=29; Airbeam 2 N=22) were calibrated four times over a 2-year timeframe between 2019-2021. Cigarette smoke-specific calibration curves for Airbeam 1 and 2 PM sensors were created by directly comparing simultaneous 1-min readings of a Thermo Scientific Personal DataRAM PDR-1500 unit with a 2.5 µm inlet.
Results

Inter-sensor variability in calibration coefficient was high, particularly in Airbeam 1 sensors at study initiation. Calibration coefficients for both sensor types trended downwards over time to <1 at final calibration timepoint [Airbeam 1 Mean (SD)= 0.87 (0.20); Airbeam 2 Mean (SD) = 0.96 (0.27)]. We lost more Airbeam 1 sensors (N=27, failure rate 48.2%) than Airbeam 2 (N=2, failure rate 16.7%) due to electronics, battery, or data output issues.
Conclusions

Evidence suggests degradation over time might depend more on particle sensor type, rather than individual usage. Repeated calibrations of low-cost particle sensors may increase confidence in reported PM levels in longitudinal indoor air pollution studies.
Disaggregation of future GCMs to generate IDF curves for the assessment of urban floods
Authors: Tayşi H. , Özger M. 
Published: October 2021

AbstractUrbanization and industrialization cause an increase in greenhouse gas emissions, which in turn causes changes in the atmosphere. Climate change is causing extreme rainfalls and these rainfalls are getting stronger day after day. Floods are threatening urban areas, and short-duration rainfall and outdated drainages are responsible for urban floods. Intensity–Duration–Frequency (IDF) curves are crucial for both drainage system design and assessment of flood risk. Once IDF curves are determined from historical data, they are assumed to be stationary. However, IDF curves must be non-stationary and time varying based on preparation for extreme events. This study generates future IDF curves with short-duration rainfalls under climate change. To represent future rainfall, an ensemble of four Global Climate Models generated under Representative Concentration Pathways (RCP) 4.5 and 8.5 were used in this study. A new approach to the HYETOS disaggregation model was applied to disaggregate daily future rainfall into sub-hourly using disaggregation parameters of hourly measured rainfalls. Hence, sub-hourly future rainfalls will be obtained capturing historical rainfall patterns instead of random rainfall characteristics. Finally, historical and future IDF curves were compared. The study concludes that increases in short-duration rainfalls will be highly intensified in both the near and distant futures with a high probability.
Climate-smart agriculture (CSA) and extension advisory service (EAS) stakeholders' prioritisation: a case study of Anantapur district, Andhra Pradesh, India
Authors: Vincent A. , Balasubramani N. 
Published: October 2021

Abstract
Several climate-smart agriculture (CSA) interventions are promoted by public, private and civil societies in India. However, there is a considerable variation among them. Therefore, to understand the different CSA interventions supported and prioritised by the public and non-governmental organisations (NGOs) as well as their impacts at the farmer level, a case study was undertaken in Anantapur district, as it is highly vulnerable to climate change risks due to the increase in temperature, delayed monsoon, erratic rainfall and frequent occurrence of droughts. A case study research method was followed to assess the CSA interventions promoted by Krishi Vigyan Kendra (KVK), Department of Agriculture, Accion and Adarsha. The findings showed that KVK has focused its extension advisory services on the promotion of field crop (e.g. groundnut)-based CSA. The extension services of NGO-Accion were aimed at promoting horticulture, and Adarsha was prioritised promoting millet-based CSA interventions. Whereas the CSA priority of the department of agriculture was driven by the prevailing zero-budget natural farming project. However, interventions of KVK and NGOs were implemented on a limited scale. Therefore, the recommendations that emerged from the study will help the stakeholders to ensure convergence and foster synergy in implementing CSA interventions at scale. Some challenges faced during the research study were difficulties in the identification of the right stakeholders who were promoting CSA, also their technologies and services related to CSA. However, after a thorough discussion with the extension officers of Anantapur district, the stakeholders were identified and their CSA interventions were ascertained through focus group discussions and secondary data reviewed from magazines and other publications. Furthermore, the present study focused only on the CSA interventions promoted by two public sectors and two NGOs, and there is a wider scope for identifying more stakeholders, e.g. private sector, FPOs and entrepreneurs, and assessing their extent of involvement in the promotion of CSA and prioritisation.

Published: October 2021

Background
Monitoring social media has been shown to be a useful means to capture patients’ opinions and feelings about medical issues, ranging from diseases to treatments. Health-related quality of life (HRQoL) is a useful indicator of overall patients’ health, which can be captured online.

Objective
This study aimed to describe a social media listening algorithm able to detect the impact of diseases or treatments on specific dimensions of HRQoL based on posts written by patients in social media and forums.

Methods
Using a web crawler, 19 forums in France were harvested, and messages related to patients’ experience with disease or treatment were specifically collected. The SF-36 (Short Form Health Survey) and EQ-5D (Euro Quality of Life 5 Dimensions) HRQoL surveys were mixed and adapted for a tailored social media listening system. This was carried out to better capture the variety of expression on social media, resulting in 5 dimensions of the HRQoL, which are physical, psychological, activity-based, social, and financial. Models were trained using cross-validation and hyperparameter optimization. Oversampling was used to increase the infrequent dimension: after annotation, SMOTE (synthetic minority oversampling technique) was used to balance the proportions of the dimensions among messages.

Results
The training set was composed of 1399 messages, randomly taken from a batch of 20,000 health-related messages coming from forums. The algorithm was able to detect a general impact on HRQoL (sensitivity of 0.83 and specificity of 0.74), a physical impact (0.67 and 0.76), a psychic impact (0.82 and 0.60), an activity-related impact (0.73 and 0.78), a relational impact (0.73 and 0.70), and a financial impact (0.79 and 0.74).

Conclusions
The development of an innovative method to extract health data from social media as real time assessment of patients’ HRQoL is useful to a patient-centered medical care. As a source of real-world data, social media provide a complementary point of view to understand patients’ concerns and unmet needs, as well as shedding light on how diseases and treatments can be a burden in their daily lives.

Published: October 2021

Abstract. This cross-sectional study analyzed by gender the association between body weight perception and weight control behavior with quality of life (QL) in 563 middle school students (age x̅ = 13.3, SD = 0.94), from all grades of nine middle schools of South region of Jalisco state realized in 2010. There were 51.9% boys and 19.8% worked. A self-administered questionnaire on line was used (YQOL-R), perceptual module, and five items of body weight adapted from 2009 Middle School YRBS. Statistical analysis included chi squared, Student t test, Spearman correlation, ANOVA and Tamhane ́s T2. Results: QOL was higher in normal weight perception category than low weight or overweight perception categories; a negative correlation between QOL and weight perception was observed (overweight rs = -.22; low weight rs = -.16); QOL was lower in those who tried to maintain weight in total sample and in girls in relation to those who tried to maintained it. We concluded that weight control behavior is associated with weight perception and both are associated with quality of life. Gender was important to understand the variables studied.

Abstract. The purpose of this review was to analyze the studies about psychometric properties of eating disorders (ED) questionnaires validated in Mexican women. We search papers published in scientific journal about psychometric properties of questionnaires to measure symptoms or characteristics associated with ED. Seventeen papers that evaluated the reliability or validity of 16 questionnaires were identified (11 were created in another countries and five were created by Mexican researchers). It was found that questionnaires have adequate reliability; however, the researchers only analyzed the internal consistency. Several methods were employed to analyze the validity of the questionnaires; the most common were factorial analysis exploratory and homogeneity of the scale. There are seven questionnaires with cut-off point, which permit to identify people at risk for ED. It was concluded that it is necessary that future researches provide further evidences about psychometric pro- perties of the revised questionnaires. Key words: Assessment, questionnaires, eating disorders, women, Mexico. Resumen. El propósito de la presente revisión fue hacer un análisis de aquellos estudios en que se han examinado las propiedades psicométricas de instrumentos de evaluación de trastornos del comportamiento alimentario (TCA) en mujeres mexicanas. Se buscaron artículos publicados en revistas científicas sobre propiedades psicométricas de instrumentos para medir síntomas o características asociadas a los TCA. Se localizaron 17 publicaciones en las que se evaluó la confiabilidad y/o validez de 16 cuestionarios de autoinforme (11 creados en otros países y cinco construidos por investigadores mexicanos). Se encontró que los instrumentos poseen confiabilidad adecuada, sin embargo, sólo se ha analizado la consistencia interna. Para evaluar la validez de los instrumentos se han empleado diferentes procedimientos, siendo el más común el análisis factorial exploratorio y el análisis de la homogeneidad de la prueba. Siete de los instrumentos cuentan con punto de corte, el cual permite identificar a personas en riesgo de desarrollar algún TCA. Se concluyó que es necesario realizar más investigaciones que fortalezcan la evidencia existente sobre las propiedades psicométricas de los instrumentos revisados.

ABSTRACT Interventions based on mindfulness are increasingly used for feeding issues, looking for an improvement in the emotional regulation and awareness of internal states (i.e., satiety, hunger). The objective of this paper was to describe the perception of mindfulness when controlling binge eating behavior. A total of seven adults with binge eating behavior (20-52 years old), six women and one men participated in the study. All participants receive a training (workshop) about mindfulness and feeding. Based on a qualitative methodological approach with exploratory and descriptive scope, semi-structured interviews were performed pre-post intervention and were analyzed by open coding. Before intervention participants had no awareness in their relationship with food showing an automatic response. After intervention participants reported favorable changes such as increased of awareness as well as cognitive and emotional recognition, which led to changes in eating behavior. The participants made a positive evaluation of the workshop and the group format, highlighting that mindfulness was internalized as a new tool for daily life.RESUMEN Intervenciones basadas en mindfulness (atención plena [AP]) están siendo cada vez más utilizadas para tratar temas alimentarios, buscando mejorar la regulación emocional y la conciencia acerca de los estados internos (e.g., hambre, saciedad). El objetivo de este trabajo fue describir la percepción de la práctica de la AP en el control de la conducta de atracón. Participaron siete adultos que presentaban conducta de atracón (20-52 años de edad), seis mujeres y un hombre. Como parte de este estudio, los participantes recibieron una intervención (taller) sobre AP y alimentación. Con base a un enfoque metodológico cualitativo, de alcance exploratorio y descriptivo, se realizaron entrevistas semiestructuradas pre-post intervención, las cuales fueron analizadas mediante codificación abierta. Antes de la intervención, los participantes sostenían una relación no consciente con la comida, presentando un modo de funcionar automático. Tras la intervención se reportaron cambios favorables, como el aumento de la conciencia y el reconocimiento cognitivo y emocional, lo cual supuso modificaciones en la conducta alimentaria. Los participantes realizaron una evaluación positiva del taller y del formato grupal, destacando que la AP fue interiorizada como una nueva herramienta para la vida diaria.

Abstract The objective of this study was to know the relationship between dietary intake (DI) and body composition (BC) with the metabolic syndrome (MS) among university students. A total of 50 students (56% female) among 19 and 25 years of age (M = 20.58, SD = 1.86), completed a questionnaire aimed at assessing DI, in addition biochemical and BC parameters were collected. According to the percentage of body fat (BF), a high prevalence of overweight (22%) and obesity (38%) was identified. In addition, visceral fat increased as the BF increased. In both sexes, there was a low consumption of carbohydrates and high in lipids, mostly of animal fat as well as high consumption of saturated fats, but low omegas 3 y 6. The MS was identified in 20% of the sample, mainly in women. The most frequently risk criteria were low levels of HDL cholesterol, followed by abdominal obesity; whereas the most frequent dyslipidemia was hypertriglyceridemia. In this study, although no direct relationship was found between DI and MS, it was found between MS and BC indicators. It is imminent the need to implement strategies that allow university students to acquire healthy eating and physical activity habits. Resumen El objetivo de este estudio fue conocer la relación de la ingesta alimentaria (IA) y la composición corporal (CMC) con el síndrome metabólico (SM) entre estudiantes universitarios. Participaron 50 alumnos (56% mujeres) de entre 19 y 25 años de edad (M = 20.58, DE = 1.86), quienes completaron un cuestionario dirigido a evaluar IA, además se recabaron parámetros bioquímicos y de CMC. De acuerdo con el porcentaje de grasa corporal (PG), se identificó una alta ocurrencia de sobrepeso (22%) y obesidad (38%). Además, la grasa visceral incrementó conforme aumentó el PG. En ambos sexos existió un consumo bajo de hidratos de carbono y alto en lípidos, mayormente de origen animal, así como alto consumo de grasas saturadas, pero bajo de omegas 3 y 6. El SM fue identificado en 20% de la muestra, principalmente mujeres. El criterio de riesgo más frecuente fueron bajos niveles séricos de colesterol HDL, seguido de la obesidad abdominal; en tanto que la dislipidemia más frecuente fue la hipertrigliceridemia. En este estudio, aunque no se encontró relación directa entre IA y SM, si de éste con indicadores de CMC. Resulta inminente la necesidad de implementar estrategias que permitan a los estudiantes universitarios adquirir hábitos alimentarios y de actividad física saludables.
