Mycorrhizal fungi modify decomposition: a meta-analysis.

It has been proposed that ectomycorrhizal fungi can reduce decomposition while arbuscular mycorrhizal fungi may enhance it. These phenomena are known as the 'Gadgil effect' and 'priming effect', respectively. However, it is unclear which one predominates globally. We evaluated whether mycorrhizal fungi decrease or increase decomposition, and identified conditions that mediate this effect. We obtained decomposition data from 43 studies (97 trials) conducted in field or laboratory settings that controlled the access of mycorrhizal fungi to substrates colonized by saprotrophs. Across studies, mycorrhizal fungi promoted decomposition of different substrates by 6.7% overall by favoring the priming effect over the Gadgil effect. However, we observed significant variation among studies. The substrate C : N ratio and absolute latitude influenced the effect of mycorrhizal fungi on decomposition and contributed to the variation. Specifically, mycorrhizal fungi increased decomposition at low substrate C : N and absolute latitude, but there was no discernable effect at high values. Unexpectedly, the effect of mycorrhizal fungi was not influenced by the mycorrhizal type. Our findings challenge previous assumptions about the universality of the Gadgil effect but highlight the potential of mycorrhizal fungi to negatively influence soil carbon storage by promoting the priming effect.

Los hongos ectomicorrízicos puden reducir la descomposición mientras que los hongos micorrízico­arbusculares pueden potenciarla. Ambos fenómenos son conocidos como "Gadgil effect" y "priming effect", respectivamente. Sin embargo, no es claro cuál predomina mundialmente. En este trabajo evaluamos si los hongos micorrízicos disminuyen o promueven la descomposición, e identificamos las condiciones que regulan este efecto. Para ello, recopilamos datos de descomposición de 43 estudios (97 observaciones) realizados en condiciones de campo o laboratorio que controlaron el acceso de los hongos micorrízicos a sustratos colonizados por saprótrofos. Los hongos micorrízicos promovieron la descomposición de diferentes sustratos en un 6.7%. Sin embargo, observamos una variación significativa entre estudios. La relación C : N del sustrato y la latitud influyeron en el efecto de los hongos micorrícicos sobre la descomposición y contribuyeron a la variabilidad. Específicamente, los hongos micorrízicos aumentaron la descomposición a valores bajos de C : N del sustrato y latitud, pero no hubo un efecto discernible en valores altos. Inesperadamente, el tipo de micorriza no influyó en el efecto de los hongos micorrízicos. Nuestros hallazgos cuestionan la universalidad del Gadgil effect, y resaltan el potencial de los hongos micorrízicos para influir negativamente en el almacenamiento de carbono del suelo al promover el priming effect.

Standardizing health outcomes for chronic kidney disease. Adaptation of the international consortium for health outcomes measurement standard set to the Spanish setting / Estandarización de los resultados de salud en la enfermedad renal crónica. Adaptación del conjunto de variables de resultados del International Consortium for Health Outcomes Measurement al entorno español

Background and objectives: We aim to adapt the International Consortium for Health Outcomes Measurements standard set for chronic kidney disease (CKD) patients to the Spanish setting and supplement it with those variables agreed upon through initiatives proposed by the Spanish Society of Nephrologists (S.E.N.). Material and methods: The working group defined a first standard set of variables based on a literature review. The S.E.N. members then assessed the suitability of each variable for inclusion (Consensus≥75%). A second draft of the standard set was generated and evaluated by the Patient advocacy group Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón (ALCER). Lastly, the working group established the final standard set of variables (Consensus≥75%). Results: The standard set targets patients with very high-risk CKD (G3a/A3 and G3b/A2-G5) in pre-end-stage kidney disease (pre-ESKD), hemodialysis (HD), peritoneal dialysis (PD), kidney transplantation (KT) or conservative care (CC). The essential follow-up variables agreed for all patients (All) were patient survival, hospitalizations, cardiovascular events, smoking status, health-related quality of life, pain, fatigue, physical function, daily activities, depression, renal function and hemoglobin. Additionally, it was agreed to collect PD survival (in PD patients), peritonitis (PD), infection/bacteremia (PD, HD, KT), vascular access type (HD), vascular access survival (HD), acute rejection (KT), post-transplant cancer (KT), albuminuria (KT) and kidney allograft survival (KT). (AU)

Antecedentes y objetivos: El objetivo del estudio es adaptar el conjunto de variables de resultados del International Consortium for Health Outcomes Measurements para pacientes con enfermedad renal crónica al ámbito español y complementarlo con aquellas variables consensuadas en iniciativas de la Sociedad Española de Nefrología. Material y métodos: El grupo de trabajo definió un primer conjunto de variables a partir de una revisión bibliográfica. Seguidamente, los miembros de la Sociedad Española de Nefrología valoraron la idoneidad de cada variable para su inclusión (consenso≥75%). Posteriormente, se generó un segundo borrador que fue evaluado por la asociación de pacientes Federación Nacional de Asociaciones para la lucha contra las enfermedades del riñón. Por último, el grupo de trabajo estableció el conjunto de variables final (consenso≥75%). Resultados: El conjunto de variables se dirige a pacientes con enfermedad renal crónica y muy alto riesgo de progresión (G3a/A3 y G3b/A2-G5) en estadios previos al tratamiento renal sustitutivo, hemodiálisis (HD), diálisis peritoneal (DP), trasplante renal (TR) o tratamiento conservador. Las variables esenciales de seguimiento acordadas para todos los pacientes fueron la supervivencia del paciente, las hospitalizaciones, los eventos cardiovasculares, el hábito tabáquico, la calidad de vida relacionada con la salud, el dolor, la fatiga, la función física, las actividades diarias, la depresión, la función renal y la hemoglobina. Además, se acordó recoger la supervivencia en DP (en pacientes en DP), peritonitis (DP), infección/bacteriemia (DP, HD, TR), tipo de acceso vascular (HD), supervivencia del acceso vascular (HD), rechazo agudo (TR), cáncer postrasplante (TR), albuminuria (TR) y supervivencia del aloinjerto renal (TR). Las variables opcionales acordadas para todos los pacientes fueron los niveles de fósforo y potasio y el control de la diabetes (en pacientes con diabetes). (AU)

The Spanish version of the reflective functioning questionnaire: Validity data in the general population and individuals with personality disorders.

INTRODUCTION: Mentalization or reflective functioning (RF) is the capacity to interpret oneself or the others in terms of internal mental states. Its failures have been linked to several mental disorders and interventions improving RF have a therapeutic effect. Mentalizing capacity of the parents influences the children's attachment. The Reflective Functioning Questionnaire (RFQ-8) is a widely used tool for the assessment of RF. No instrument is available to assess general RF in Spanish-speaking samples. The aim of this study is to develop a Spanish version of the RFQ-8 and to evaluate its reliability and validity in the general population and in individuals with personality disorders. METHODS: 602 non-clinical and 41 personality disordered participants completed a Spanish translation of the RFQ and a battery of self-reported questionnaires assessing several RF related constructs (alexithymia, perspective taking, identity diffusion and mindfulness), psychopathology (general and specific) and interpersonal problems. Temporal stability was tested in a non-clinical sub-sample of 113 participants. RESULTS: Exploratory and confirmatory factor analyses suggested a one-factor structure in the Spanish version of the RFQ-8. RFQ-8 understood as a single scale was tested, with low scorings reflecting genuine mentalizing, and high scorings uncertainty. The questionnaire showed good internal consistence in both samples and moderate temporal stability in non-clinical sample. RFQ correlated significantly with identity diffusion, alexithymia, and general psychopathology in both samples; and with mindfulness, perspective taking, and interpersonal problems in clinical sample. Mean values of the scale were significantly higher in the clinical group. DISCUSSION: This study provides evidence that the Spanish version of the RFQ-8, understood as a single scale, has an adequate reliability and validity assessing failures in reflective functioning (i.e., hypomentalization) in general population and personality disorders.

The optional variables agreed were phosphorus (All), potassium (All), diabetes control (All with diabetes), and albuminuria (pre-ESKD). CONCLUSIONS: This standard set may constitute a highly efficient tool allowing the evaluation of patient outcomes and helping to define strategies to enhance CKD patients' quality of care in the Spanish healthcare system.

Nursing Student Satisfaction with the Teaching Methodology Followed during the COVID-19 Pandemic.

Background: Halfway through the 2019−2020 academic year, the entire university system was affected by an exceptional situation caused by the COVID-19 pandemic. Online learning was globally implemented for all degrees to finish the course and to meet academic objectives. This unforeseen change in teaching and subsequent evaluations meant teachers and students had to invest significant effort. Student satisfaction is used to measure the evaluation of teaching/learning processes in higher education. Our objective was to know and compare the satisfaction of nursing students taught at a Spanish public university after making changes to the teaching methodology. Methods: A descriptive observational study that measures student satisfaction. Study population: 240 students registered in academic years 2019−2020 and 2020−2021 answered the survey. The survey contained 30 items answered on a Likert-type scale. The main variables: the learning methodology (online or blended) was the independent variable; student satisfaction was the dependent variable. Descriptive and bivariate analyses were performed. Results: A response rate between 37.4% and 41.2%. Overall satisfaction was 2.75 points (SD 0.56) and 2.94 points (SD 0.49) with online learning and bimodal learning, respectively (maximum score 4 points) (p < 0.004). Conclusions: Student satisfaction was moderate−high for both learning methodologies. Students found that the b-learning methodology was the most valued.

Predictive Model of Quality of Life in Patients with Parkinson's Disease.

Parkinson's disease is a chronic, progressive, and disabling neurodegenerative disease which evolves until the end of life and triggers different mood and organic alterations that influence health-related quality of life. The objective of our study was to identify the factors that negatively impact the quality of life of patients with Parkinson's disease and construct a predictive model of health-related quality of life in these patients. METHODS: An analytical, prospective observational study was carried out, including Parkinson's patients at different stages in the Albacete Health Area. The sample consisted of 155 patients (T0) who were followed up at one (T1) and two years (T2). The instruments used were a purpose-designed data collection questionnaire and the "Parkinson's Disease Questionnaire" (PDQ-39), with a global index where a higher score indicates a worse quality of life. A multivariate analysis was performed by multiple linear regression at T0. Next, the model's predictive capacity was evaluated at T1 and T2 using the area under the ROC curve (AUROC). RESULTS: Predictive factors were: sex, living in a residence, using a cane, using a wheelchair, having a Parkinson's stage of HY > 2, having Alzheimer's disease or a major neurocognitive disorder, having more than five non-motor symptoms, polypharmacy, and disability greater than 66%. This model showed good predictive capacity at one year and two years of follow-up, with an AUROC of 0.89 (95% CI: 0.83-0.94) and 0.83 (95% CI: 0.76-0.89), respectively. CONCLUSIONS: A predictive model constructed with nine variables showed a good discriminative capacity to predict the quality of life of patients with Parkinson's disease at one and two years of follow-up.

Clinical Risk Factors for Mortality Among Critically Ill Mexican Patients With COVID-19.

Little literature exists about critically ill patients with coronavirus disease 2019 (COVID-19) from Latin America. Here, we aimed to describe the clinical characteristics and mortality risk factors in mechanically ventilated COVID-19 patients from Mexico. For this purpose, we recruited 67 consecutive mechanically ventilated COVID-19 patients which were grouped according to their clinical outcome (survival vs. death). Clinical risk factors for mortality were identified by machine-learning and logistic regression models. The median age of participants was 42 years and 65% were men. The most common comorbidity observed was obesity (49.2%). Fever was the most frequent symptom of illness (88%), followed by dyspnea (84%). Multilobe ground-glass opacities were observed in 76% of patients by thoracic computed tomography (CT) scan. Fifty-two percent of study participants were ventilated in prone position, and 59% required cardiovascular support with norepinephrine. Furthermore, 49% of participants were coinfected with a second pathogen. Two-thirds of COVID-19 patients developed acute kidney injury (AKIN). The mortality of our cohort was 44.7%. AKIN, uric acid, lactate dehydrogenase (LDH), and a longitudinal increase in the ventilatory ratio were associated with mortality. Baseline PaO2/FiO2 values and a longitudinal recovery of lymphocytes were protective factors against mortality. Our study provides reference data about the clinical phenotype and risk factors for mortality in mechanically ventilated Mexican patients with COVID-19.

Clinical and Immunological Factors That Distinguish COVID-19 From Pandemic Influenza A(H1N1).

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), is a global health threat with the potential to cause severe disease manifestations in the lungs. Although COVID-19 has been extensively characterized clinically, the factors distinguishing SARS-CoV-2 from other respiratory viruses are unknown. Here, we compared the clinical, histopathological, and immunological characteristics of patients with COVID-19 and pandemic influenza A(H1N1). We observed a higher frequency of respiratory symptoms, increased tissue injury markers, and a histological pattern of alveolar pneumonia in pandemic influenza A(H1N1) patients. Conversely, dry cough, gastrointestinal symptoms and interstitial lung pathology were observed in COVID-19 cases. Pandemic influenza A(H1N1) was characterized by higher levels of IL-1RA, TNF-α, CCL3, G-CSF, APRIL, sTNF-R1, sTNF-R2, sCD30, and sCD163. Meanwhile, COVID-19 displayed an immune profile distinguished by increased Th1 (IL-12, IFN-γ) and Th2 (IL-4, IL-5, IL-10, IL-13) cytokine levels, along with IL-1ß, IL-6, CCL11, VEGF, TWEAK, TSLP, MMP-1, and MMP-3. Our data suggest that SARS-CoV-2 induces a dysbalanced polyfunctional inflammatory response that is different from the immune response against pandemic influenza A(H1N1). Furthermore, we demonstrated the diagnostic potential of some clinical and immune factors to differentiate both diseases. These findings might be relevant for the ongoing and future influenza seasons in the Northern Hemisphere, which are historically unique due to their convergence with the COVID-19 pandemic.

Evolution of Quality of Life in Persons with Parkinson's Disease: A Prospective Cohort Study.

Parkinson's disease (PD) is a chronic neurodegenerative disorder that results in important functional symptoms, altered mood, and deterioration in quality of life (QoL). This study aimed to determine the evolution of the QoL in persons with PD in the Albacete health district over a two-year period and identify associated sociodemographic, clinical, and socio-health characteristics. A cohort study was conducted of patients at different stages of PD in the Albacete health district. Calculated sample size: 155 patients. Instruments: A purpose-designed questionnaire for data collection and the "Parkinson Disease Questionnaire" (PDQ-39), which measures 8 dimensions and a global index where a higher score indicates worse quality of life. Three measurements were made: baseline, one year, two years. A descriptive and bivariate analysis was conducted. Ethical aspects: informed consent, anonymized data. Results: Mean age 69.51 (standard deviation, SD 8.73) years, 60% male, 75.5% married, and 85.5% lived with family. The most frequent motor symptoms were slow movement (86.23%), postural instability (55.5%), tremor (45.5%), and dyskinesia (24.6%). Among the non-motor symptoms were fatigue (66.2%), pain, daytime somnolence, constipation, and apathy, with approximately 50% each. The mean QoL score at baseline was 27.47 (SD 16.14); 95% CI (confidence interval) 24.91-30.03. At two years, global QoL had slightly worsened (28.3; SD 17.26; 95% CI 25.41-31.18), with a statistically significant worsening in mobility, activities of daily living, and communication, whereas social support improved.

CXCL17 Is a Specific Diagnostic Biomarker for Severe Pandemic Influenza A(H1N1) That Predicts Poor Clinical Outcome.

The C-X-C motif chemokine ligand 17 (CXCL17) is chemotactic for myeloid cells, exhibits bactericidal activity, and exerts anti-viral functions. This chemokine is constitutively expressed in the respiratory tract, suggesting a role in lung defenses. However, little is known about the participation of CXCL17 against relevant respiratory pathogens in humans. Here, we evaluated the serum levels and lung tissue expression pattern of CXCL17 in a cohort of patients with severe pandemic influenza A(H1N1) from Mexico City. Peripheral blood samples obtained on admission and seven days after hospitalization were processed for determinations of serum CXCL17 levels by enzyme-linked immunosorbent assay (ELISA). The expression of CXCL17 was assessed by immunohistochemistry (IHQ) in lung autopsy specimens from patients that succumbed to the disease. Serum CXCL17 levels were also analyzed in two additional comparative cohorts of coronavirus disease 2019 (COVID-19) and pulmonary tuberculosis (TB) patients. Additionally, the expression of CXCL17 was tested in lung autopsy specimens from COVID-19 patients. A total of 122 patients were enrolled in the study, from which 68 had pandemic influenza A(H1N1), 24 had COVID-19, and 30 with PTB. CXCL17 was detected in post-mortem lung specimens from patients that died of pandemic influenza A(H1N1) and COVID-19. Interestingly, serum levels of CXCL17 were increased only in patients with pandemic influenza A(H1N1), but not COVID-19 and PTB. CXCL17 not only differentiated pandemic influenza A(H1N1) from other respiratory infections but showed prognostic value for influenza-associated mortality and renal failure in machine-learning algorithms and regression analyses. Using cell culture assays, we also identified that human alveolar A549 cells and peripheral blood monocyte-derived macrophages increase their CXCL17 production capacity after influenza A(H1N1) pdm09 virus infection. Our results for the first time demonstrate an induction of CXCL17 specifically during pandemic influenza A(H1N1), but not COVID-19 and PTB in humans. These findings could be of great utility to differentiate influenza and COVID-19 and to predict poor prognosis specially at settings of high incidence of pandemic A(H1N1). Future studies on the role of CXCL17 not only in severe pandemic influenza, but also in seasonal influenza, COVID-19, and PTB are required to validate our results.

Expression of Surfactant Protein D Distinguishes Severe Pandemic Influenza A(H1N1) from Coronavirus Disease 2019.

The differentiation between influenza and coronavirus disease 2019 (COVID-19) could constitute a diagnostic challenge during the ongoing winter owing to their clinical similitude. Thus, novel biomarkers are required to enable making this distinction. Here, we evaluated whether the surfactant protein D (SP-D), a collectin produced at the alveolar epithelium with known immune properties, was useful to differentiate pandemic influenza A(H1N1) from COVID-19 in critically ill patients. Our results revealed high serum SP-D levels in patients with severe pandemic influenza but not those with COVID-19. This finding was validated in a separate cohort of mechanically ventilated patients with COVID-19 who also showed low plasma SP-D levels. However, plasma SP-D levels did not distinguish seasonal influenza from COVID-19 in mild-to-moderate disease. Finally, we found that high serum SP-D levels were associated with death and renal failure among severe pandemic influenza cases. Thus, our studies have identified SP-D as a unique biomarker expressed during severe pandemic influenza but not COVID-19.

Preventing Functional Urinary Incontinence in Hip-Fractured Older Adults Through Patient Education: A Randomized Controlled Trial.

The purpose of this study was to evaluate whether an educational intervention would reduce the incidence of functional urinary incontinence (UI) in older adults with a fall-related hip fracture. The project was conducted as a multicenter randomized controlled trial (RCT). A total of 109 patients that had been admitted to six hospitals in Castilla-La Mancha (Spain) for acute treatment of hip fracture, previously continent and without cognitive impairment, were enrolled and randomly assigned to the experimental group (EG) or the control group (CG). Intervention (on EG): urinary habit training (Nursing Interventions Classifications taxonomy) was performed during hospital stay (second to fourth postoperative day), with a telephonic reinforcement 10 days after discharge. The CG received routine care. Primary outcome measure: incidence of UI. Follow-up: telephone assessment 3 and 6 months after discharge (blinded evaluation). The incidence of UI at 6 months was 49% (CG) versus 25.5% (EG) (relative risk = 0.52, 95% confidence interval [0.3, 0.9]; number necessary to treat = 4). The mean of UI episodes was 0.54 (EG) versus 1.8 (CG), p = .007. The educational intervention prevents the development of UI and decreases the number of episodes in case of appearance, in a statistically significant way.

Relationship between Motor and Nonmotor Symptoms and Quality of Life in Patients with Parkinson's Disease.

BACKGROUND: Parkinson's disease (PD) is a chronic neurodegenerative disease that implies a progressive and invalidating functional organic disorder, which continues to evolve till the end of life and causes different mental and physical alterations that influence the quality of life of those affected. OBJECTIVE: To determine the relationship between motor and nonmotor symptoms and the quality of life of persons with PD. METHODS: An analytic, descriptive, cross-sectional study was conducted with patients with different degrees of PD in the Albacete Health district. The estimated sample size required was 155 patients. The instruments used for data collection included a purpose-designed questionnaire and "Parkinson's Disease Questionnaire" (PDQ-39), which measures eight dimensions and has a global index where a higher score indicates a worse quality of life. A descriptive and bivariate analysis was conducted (SPSS® IBM 24.0). Ethical aspects: informed consent and anonymized data. RESULTS: A strong correlation was found between the number of motor and nonmotor symptoms and global health-related quality of life and the domains mobility, activities of daily living, emotional well-being, cognitive status, and pain (p < 0.05). Receiving pharmacological treatment and taking more than four medicines per day was significantly associated with a worse quality of life (p < 0.05). Patients who had undergone surgical treatment did not show better global quality of life (p = 0.076). CONCLUSIONS: All nonmotor symptoms and polypharmacy were significantly associated with a worse global quality of life.

Evaluation of dialysis centres: values and criteria of the stakeholders.

BACKGROUND: Evaluation of renal replacement therapy with haemodialysis is essential for its improvement. Remarkably, outcomes vary across centres. In addition, the methods used have important epistemological limitations, such as ignoring significant features (e.g., quality of life) or no relevance given to the patient's perspective in the indicator's selection. The present study aimed to determine the opinions and preferences of stakeholders (patients, clinicians, and managers) and establish their relative importance, considering the complexity of their interactions, to facilitate a comprehensive evaluation of haemodialysis centres. METHODS: Successive working groups (WGs) were established using a multicriteria methodology. WG1 created a draft of criteria and sub-criteria, WG2 agreed, using a qualitative structured analysis with pre-established criteria, and WG3 was composed of three face-to-face subgroups (WG3-A, WG3-B, and WG3-C) that weighted them using two methodologies: weighted sum (WS) and analytic hierarchy process (AHP). Subsequently, they determined a preference for the WS or AHP results. Finally, via the Internet, WG4 weighted the criteria and sub-criteria by the method preferred by WG3, and WG5 analysed the results. RESULTS: WG1 and WG2 identified and agreed on the following evaluation criteria: evidence-based variables (EBVs), annual morbidity, annual mortality, patient-reported outcome measures (PROMs), and patient-reported experience measures (PREMs). The EBVs consisted of five sub-criteria: type of vascular access, dialysis dose, haemoglobin concentration, ratio of catheter bacteraemia, and bone mineral disease. The patients rated the PROMs with greater weight than the other stakeholders in both face-to-face WG3 (WS and AHP) and WG4 via the Internet. The type of vascular access was the most valued sub-criterion. A performance matrix of each criterion and sub-criterion is presented as a reference for assessing the results based on the preferences of the stakeholders. CONCLUSIONS: The use of a multicriteria methodology allows the relative importance of the indicators to be determined, reflecting the values of the different stakeholders. In a performance matrix, the inclusion of values and intangible aspects in the evaluation could help in making clinical and organizational decisions.

Novel benzoate-lipophilic cations selectively induce cell death in human colorectal cancer cell lines.

INTRODUCTION: Colorectal cancer (CRC) is a critical health issue worldwide. The high rate of liver and lung metastasis associated with CRC creates a significant barrier to effective and efficient therapy. Tumour cells, including CRC cells, have metabolic alterations, such as high levels of glycolytic activity, increased cell proliferation and invasiveness, and chemo- and radio-resistance. However, the abnormally elevated mitochondrial transmembrane potential of these cells also provides an opportunity to develop drugs that selectively target the mitochondrial functions of tumour cells. METHODS: In this work, we used a new batch of benzoic acid esters with cytotoxic activities attached to the triphenylphosphonium group as a vehicle to target tumour mitochondria and improve their activity. We evaluated the cytotoxicity, selectivity, and mechanism of action of these derivatives, including the effects on energy stress-induced apoptosis and metabolic behaviour in the human CRC cell lines HCT-15 and COLO-205. RESULTS: The benzoic acid derivatives selectively targeted the tumour cells with high potency and efficacy. The derivatives induced the uncoupling of the oxidative phosphorylation system, decreased the transmembrane potential, and reduced ATP levels while increasing AMPK activation, thereby triggering tumour cell apoptosis in both tumour cell lines tested. CONCLUSION: The benzoic acid derivatives studied here are promising candidates for assessing in vivo models of CRC, despite the diverse metabolic characteristics of these tumour cells.

Understanding the Psychological Distress of Food Insecurity: A Qualitative Study of Children's Experiences and Related Coping Strategies.

BACKGROUND: Food insecurity, a condition of inadequate household food availability, affects 15.7% of US households with children. Food insecurity is generally believed to affect the quantity and quality of food consumed. However, an understudied but important aspect of the experience of food insecurity is psychological distress. OBJECTIVE: To critically explore the psychological distress associated with children's food insecurity using children's own reports of their experiences. DESIGN: In-depth qualitative interviews conducted with children to better understand the psychological distress associated with food insecurity. PARTICIPANTS/SETTING: Sixty children (aged 7 to 14 years) were recruited from the San Francisco Bay Area. Children were eligible in the case that they spoke English fluently and their parent reported any experience of household food insecurity during the past year. RESULTS: Children discussed six themes related to the psychological distress associated with food insecurity: worrying about not having enough food, worrying about their parents' well-being, anger and frustration about not having enough food, embarrassment about their family's food situation, strain on the family's dynamics due to food insecurity, and sadness over not having enough food. After describing their experiences, children described strategies they employed to tolerate or cope with food insecurity, including distracting from or using their imagination to cope with food insecurity, increasing tolerance of their family's food situation, and appreciating their parents for providing food and resources. CONCLUSIONS: Food insecurity contributes to children's psychological distress. Given the known effects of chronic stress in childhood, the psychological distress of food insecurity may represent an important mechanism by which food insecurity adversely influences children's growth and development and deserves investigation in future studies.

Beneficios de la terapia asistida por caballos en las variables de la marcha en personas mayores de 18 años, con deficiencias motoras secundarias, ante un accidente cerebrovascular o esclerosis múltiple / Benefits of Equine-Assisted Therapy on the Gait Variables in People Older Than 18 Years with Motor Impairments Secondary to Stroke or Multiple Sclerosis / Benefícios da terapia assistida por cavalo nas variáveis de marcha em pessoas maiores de 18 anos com alterações motoras secundárias a acidente vascular cerebral ou esclerose múltipla

Resumen El propósito de este artículo es analizar los resultados obtenidos sobre los beneficios de la terapia asistida por caballos, en variables de la marcha (equilibrio, coordinación y control postural), en personas mayores de 18 años con deficiencias corporales o fisiológicas, transitorias o permanentes, secundarias, ante un accidente cerebrovascular (isquémico o hemorrágico) o EM (recaída-remisión o secundaria progresiva), luego de haber participado en entrenamientos de dicha terapia. La metodología utilizada fue una revisión narrativa de la literatura existente, con método de búsqueda sistemático, en las siguientes bases de datos: PubMed, SciELO, LILACS y Scopus, con el fin de realizar una actualización bibliográfica del tema. Finalmente, se seleccionaron 11 artículos (revisiones sistemáticas, ECA, estudio control) para su posterior análisis. Los resultados de estos artículos coinciden en que el uso de la terapia asistida por caballos pudiera ser efectiva en la mejora de las variables ya mencionadas. No obstante, la información existente en las distintas plataformas de búsqueda es escasa, por lo que surge la necesidad de llevar a cabo estudios con un tamaño de muestra representativo, en los que se utilicen las mismas escalas de evaluación, con el propósito de poder objetivar y homologar los resultados. A modo de conclusión, se establece que hoy existen estudios, originados en diferentes partes del mundo, los cuales indican que la terapia asistida por caballos podría ser una herramienta efectiva en la rehabilitación de los distintos componentes que afectan la marcha, como el equilibrio o la coordinación, en personas con deficiencias motoras secundarias, ante un ACV (isquémico o hemorrágico) o EM (recaída-remisión o secundaria progresiva). En consecuencia, se podría considerar la utilización de la terapia asistida por caballos como una herramienta terapéutica, en el proceso de rehabilitación de la marcha en personas mayores de 18 años con daño neurológico.

Abstract We analyzed the results obtained from the benefits of equine-assisted therapy in gait variables (balance, coordination and postural control) on people over eighteen years old with transitory or permanent physical and/or physiological deficiencies secondary to stroke (ischemic or hemorrhagic) or multiple sclerosis (relapseremission and/or secondary progressive) after their participation in the therapy. The methodology used was a narrative review of the existing up-to-date literature with a systematic research method on the following databases: PubMed, SciELO, LILACS, and Scopus in order to make a bibliographical update about the topic. At last, eleven articles were selected for further analysis (systematic reviews, Randomized Clinical Trial, a case-control study). The results of these articles agree that the use of equine-assisted therapy can be effective in improving the variables mentioned above. However, there is not enough information available on different search engines, so there is a need to conduct studies with a representative sample size where they have to use the same evaluation scales in order to be able to objectify and standardize the results. Conclusion: nowadays around the world there are different studies, which indicate that equine-assisted therapy can be an effective tool in the rehabilitation of the different components that affect gait, such as balance or coordination, in people with motor impairments secondary to stroke (ischemic or hemorrhagic) or Multiple Sclerosis (relapseremission and/or secondary progressive). Therefore, we could consider the use of equine-assisted therapy as a therapeutic tool in the rehabilitation process of gait in people over eighteen years old with neurological damage.

Resumo O objetivo deste artigo é analisar os resultados obtidos sobre os benefícios da terapia assistida por cavalo nas variáveis de marcha (equilíbrio, coordenação e controle postural) em pessoas maiores de 18 anos com deficiências fisiológicas e/ou corporais transitórias ou permanentes, secundárias a um Acidente Cerebrovascular (isquêmico e/ou hemorrágico) ou EM (recidiva-remissão e/ou secundário progressivo), após terem participado do treinamento dessa terapia. A Metodologia utilizada foi uma revisão narrativa da literatura existente atualizada com método de busca sistemática, nas seguintes bases de dados: PubMed, SciELO, LILACS e Scopus a fim de atualizar a bibliografia sobre o assunto. Onze artigos (revisões sistemáticas, ECRs, estudo de controle) foram finalmente selecionados para análise posterior. Os resultados desses artigos concordam que o uso da terapia assistida por cavalo pode ser eficaz para melhorar as variáveis já mencionadas. No entanto, a informação existente nas diferentes plataformas de pesquisa é escassa, pelo que existe a necessidade de realizar estudos com um tamanho amostral representativo, em que sejam utilizadas as mesmas escalas de avaliação, a fim de se poder objetivar e padronizar os resultados. Conclusão: Atualmente existem estudos realizados em diferentes partes do mundo que indicam que a terapia assistida por cavalo pode ser uma ferramenta eficaz na reabilitação dos diferentes componentes que afetam a marcha, como o equilíbrio ou a coordenação, em pessoas com alterações motoras secundárias a um AVC (isquêmico e/ou hemorrágico) ou EM (recaída-remissão e/ou secundário progressivo). Consequentemente, o uso da terapia assistida por cavalo pode ser considerado como uma ferramenta terapêutica no processo de reabilitação da marcha em pessoas maiores de 18 anos com lesão neurológica.

Food Insecurity Is Associated with Lower Cognitive Functioning in a National Sample of Older Adults.

BACKGROUND: Food insecurity, a social and economic condition of inadequate food resources, is known to affect cognitive development in children. However, research is sparse among adult populations, particularly older adults who may be more susceptible to accelerated cognitive decline. OBJECTIVE: The aim of this study was to examine the associations between food insecurity and cognitive functioning among older adults. METHODS: Data came from 1823 older adults (≥60 y) with incomes ≤300% of the federal poverty level (FPL) from the 2011-2014 NHANES. Food security was measured using the 10-item Adult Food Security Survey Module. Cognitive function was measured using the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) word learning subtest and delayed word recall, the Animal Fluency Test (AFT), and the Digit Symbol Substitution Test (DSST). The cognitive assessments were then standardized and an overall cognitive function z score was created by averaging across all cognitive assessments. Associations with food insecurity were examined using multivariate linear regression models, adjusting for sociodemographic and health characteristics. RESULTS: In the analytic population, the prevalence of food insecurity was 23.7%. Across all cognitive assessments, the mean scores among food-insecure adults was significantly lower than the mean scores among food-secure adults. After adjusting for sociodemographic and health characteristics, food insecurity was associated with lower scores on the CERAD word learning subtest (ß = -0.14, 95% CI: -0.26, -0.01), the AFT (ß = -0.13, 95% CI: -0.25, -0.002), and the DSST (ß = -0.24, 95% CI: -0.33, -0.15). Food insecurity was also associated with a lower score on the overall cognitive function z score (ß = -0.15, 95% CI: -0.26, -0.05). CONCLUSIONS: In this national sample of 1823 adults aged ≥60 y, food insecurity was inversely associated with cognitive function, which may translate into higher risk of cognitive impairment over time.

Development of an International Standard Set of Value-Based Outcome Measures for Patients With Chronic Kidney Disease: A Report of the International Consortium for Health Outcomes Measurement (ICHOM) CKD Working Group.

Value-based health care is increasingly promoted as a strategy for improving care quality by benchmarking outcomes that matter to patients relative to the cost of obtaining those outcomes. To support the shift toward value-based health care in chronic kidney disease (CKD), the International Consortium for Health Outcomes Measurement (ICHOM) assembled an international working group of health professionals and patient representatives to develop a standardized minimum set of patient-centered outcomes targeted for clinical use. The considered outcomes and patient-reported outcome measures were generated from systematic literature reviews. Feedback was sought from patients and health professionals. Patients with very high-risk CKD (stages G3a/A3 and G3b/A2-G5, including dialysis, kidney transplantation, and conservative care) were selected as the target population. Using an online modified Delphi process, outcomes important to all patients were selected, such as survival and hospitalization, and to treatment-specific subgroups, such as vascular access survival and kidney allograft survival. Patient-reported outcome measures were included to capture domains of health-related quality of life, which were rated as the most important outcomes by patients. Demographic and clinical variables were identified to be used as case-mix adjusters. Use of these consensus recommendations could enable institutions to monitor, compare, and improve the quality of their CKD care.
