Longitudinal associations between parental mathematics anxiety and attitudes and young children's mathematics attainment.

The associations between parental mathematics anxiety and attitudes and children's mathematics attainment in early primary school were explored. Initially, parents of preschool children (Mage = 3;11 [years;months]) completed a questionnaire indexing parental mathematics anxiety and attitudes and the frequency of preschool home number experiences. The children completed mathematics assessments in their first year (n = 231, Mage = 5;2) and second year (n = 119, Mage = 6;3) of schooling and a mathematics anxiety questionnaire in their third year of schooling (n = 119, Mage = 6;7). A questionnaire indexing the frequency of primary school home number experiences was completed by 119 of the parents in their children's second year of schooling (Mage = 6;0). All indices of parental mathematics anxiety and attitudes predicted children's mathematics attainment in their first school year. These associations were independent of parental mathematics attainment and were not mediated by the frequency of preschool home number experiences. Furthermore, the positive association between preschool home number experiences and children's mathematics attainment was not weaker in the context of high parental mathematics anxiety or negative parental mathematics attitudes. One index of parental mathematics attitudes predicted children's mathematics attainment in their second school year, but this association was not significant when prior attainment was controlled. There was a stronger association between maternal mathematics anxiety and girls' attainment versus boys' attainment. Parental mathematics anxiety did not predict children's mathematics anxiety. The findings suggest that children whose parents have high mathematics anxiety or negative mathematics attitudes are more likely to have lower mathematics attainment in their first year of school. However, the mechanism underpinning this association is not yet established.

Geriatric Assessment and In-Hospital Economic Cost of Elderly Patients With Acute Coronary Syndromes.

BACKGROUND: Elderly patients with acute coronary syndromes (ACS) are at higher risk for complications and health care resources expenditure. No previous study has assessed the specific contribution of frailty and other geriatric syndromes to the in-hospital economic cost in this setting. METHOD: Unselected patients with ACS aged ≥75 years were prospectively included. A comprehensive geriatric assessment was performed during hospitalisation. Hospitalisation-related cost per patient was calculated with an analytical accountability method, including hospital stay-related expenditures, interventions, and consumption of devices. Expenditure was expressed in Euros (2019). The contribution of geriatric syndromes and clinical factors to the economic cost was assessed with a linear regression method. RESULTS: A total of 194 patients (mean age 82.6 years) were included. Mean length of hospital stay was 11.3 days. The admission-related economic cost was €6,892.15 per patient. Most of this cost was attributable to hospital length of stay (77%). The performance of an invasive strategy during the admission was associated with economic cost (p=0.008). Of all the ageing-related variables, comorbidity showed the most significant association with economic cost (p=0.009). Comorbidity, disability, nutritional risk, and frailty were associated with the hospital length of stay-related component of the economic cost. The final predictive model of economic cost included age, previous heart failure, systolic blood pressure, Killip class at admission, left main disease, and Charlson index. CONCLUSIONS: Management of ACS in elderly patients is associated with a significant economic cost, mostly due to hospital length of stay. Comorbidity mostly contributes to in-hospital resources expenditure, as well as the severity of the coronary event.

Nursing contribution to the achievement of prioritized objectives in primary health care: a cross-sectional study.

BACKGROUND: Concern for the sustainability of health care systems has forced health authorities and insurance companies to develop performance measurement systems to promote the achievement of health objectives. These actions aim to stimulate quality improvement while controlling costs by making providers accountable for what they do as well as for the quality of the care they provide. However, the extent to which each professional contributes to the achievement of the health objectives is largely unknown. The aim of this study was to analyse the contribution of nurses to achieving the objectives for primary health care (PHC) services prioritized by the public insurer. METHODS: A cross-sectional study was conducted using data from the PHC services of the public healthcare network in Catalonia, Spain, during the period 2006-09. Indicators linked to the prioritized health objectives were classified as nursing sensitive and non-nursing sensitive using criteria defined by international institutions. A multilevel linear regression model was applied to evaluate the temporal evolution of the two sets of indicators. RESULTS: Specifically, 39.4% of the indicators linked to the health objectives were nursing sensitive. The evolution of the indicators showed an improvement in the achievement of most of the prioritized objectives. Although this improvement was greater for nursing-sensitive indicator outcomes, the difference did not reach statistical significance (P = 0.09). CONCLUSION: Nursing has a relevant role in the achievement of a significant number of health objectives in PHC services. This contribution should be recognized as it has important consequences in terms of service payment and public health.

Identifying the cognitive predictors of early counting and calculation skills: Evidence from a longitudinal study.

The extent to which phonological, visual-spatial short-term memory (STM), and nonsymbolic quantitative skills support the development of counting and calculation skills was examined in this 14-month longitudinal study of 125 children. Initial assessments were made when the children were 4 years 8 months old. Phonological awareness, visual-spatial STM, and nonsymbolic approximate discrimination predicted growth in early calculation skills.These results suggest that both the approximate number system and domain-general phonological and visual-spatial skills support early calculation. In contrast, only performance on a small nonsymbolic quantity discrimination task (where the presented quantities were always within the subitizing range) predicted growth in cardinal counting skills. These results suggest that the development of counting and the development of calculation are supported by different cognitive abilities.

Optimizing Thermoelectric Properties through Compositional Engineering in Ag-Deficient AgSbTe2 Synthesized by Arc Melting.

Thermoelectric materials offer a promising avenue for energy management, directly converting heat into electrical energy. Among them, AgSbTe2 has gained significant attention and continues to be a subject of research at further improving its thermoelectric performance and expanding its practical applications. This study focuses on Ag-deficient Ag0.7Sb1.12Te2 and Ag0.7Sb1.12Te1.95Se0.05 materials, examining the impact of compositional engineering within the AgSbTe2 thermoelectric system. These materials have been rapidly synthesized using an arc-melting technique, resulting in the production of dense nanostructured pellets. Detailed analysis through scanning electron microscopy (SEM) reveals the presence of a layered nanostructure, which significantly influences the thermoelectric properties of these materials. Synchrotron X-ray diffraction reveals significant changes in the lattice parameters and atomic displacement parameters (ADPs) that suggest a weakening of bond order in the structure. The thermoelectric characterization highlights the enhanced power factor of Ag-deficient materials that, combined with the low glass-like thermal conductivity, results in a significant improvement in the figure of merit, achieving zT values of 1.25 in Ag0.7Sb1.12Te2 and 1.01 in Ag0.7Sb1.12Te1.95Se0.05 at 750 K.

Invasive Treatment Strategy in Adults With Frailty and Non-ST-Segment Elevation Myocardial Infarction: A Secondary Analysis of a Randomized Clinical Trial.

Importance: The MOSCA-FRAIL randomized clinical trial compared invasive and conservative treatment strategies in patients with frailty with non-ST-segment elevation myocardial infarction (NSTEMI). It showed no differences in the number of days alive and out of the hospital at 1 year. Objective: To assess the outcomes of the MOSCA-FRAIL trial during extended follow-up. Design, Setting, and Participants: The MOSCA-FRAIL randomized clinical trial was conducted at 13 hospitals in Spain between July 7, 2017, and January 9, 2021, and included 167 adults (aged ≥70 years) with frailty (Clinical Frailty Scale score ≥4) and NSTEMI. In this preplanned secondary analysis, follow-up was extended to January 31, 2023. Data analysis was performed from April 5 to 29, 2023, using the intention-to-treat principle. Interventions: Patients were randomized to a routine invasive (coronary angiography and revascularization if feasible [n = 84]) or a conservative (medical treatment with coronary angiography only if recurrent ischemia [n = 83]) strategy. Main outcomes and measures: The primary end point was the difference in restricted mean survival time (RMST). Secondary end points included readmissions for any cause, considering recurrent readmissions. Results: Among the 167 patients included in the analysis, the mean (SD) age was 86 (5) years; 79 (47.3%) were men and 88 (52.7%) were women. A total of 93 deaths and 367 readmissions accrued. The RMST for all-cause death over the entire follow-up was 3.13 (95% CI, 2.72-3.60) years in the invasive and 3.06 (95% CI, 2.84-3.32) years in the conservative treatment groups. The RMST analysis showed inconclusive differences in survival time (invasive minus conservative difference, 28 [95% CI, -188 to 230] days). Patients under invasive treatment tended to have shorter survival in the first year (-28 [95% CI, -63 to 7] days), which improved after the first year (192 [95% CI, 90-230] days). Kaplan-Meier mortality curves intersected, displaying higher mortality to 1 year in the invasive group that shifted to a late benefit (landmark analysis hazard ratio, 0.58 [95% CI, 0.33-0.99]; P = .045). Early harm was more evident in the subgroup with a Clinical Frailty Scale score greater than 4. No differences were found for the secondary end points. Conclusions and Relevance: In this extended follow-up of a randomized clinical trial of patients with frailty and NSTEMI, an invasive treatment strategy did not improve outcomes at a median follow-up of 1113 (IQR, 443-1441) days. However, a differential distribution of deaths was observed, with early harm followed by later benefit. The phenomenon of depletion of susceptible patients may be responsible for this behavior.

Narcolepsy and pregnancy: a retrospective European evaluation of 249 pregnancies.

In a retrospective cohort study undertaken in 12 European countries, 249 female narcoleptic patients with cataplexy (n = 216) and without cataplexy (n = 33) completed a self-administrated questionnaire regarding pregnancy and childbirth. The cohort was divided further into patients whose symptoms of narcolepsy started before or during pregnancy (308 pregnancies) and those in whom the first symptoms of narcolepsy appeared after delivery (106 pregnancies). Patients with narcolepsy during pregnancy were older during their first pregnancy (P < 0.001) and had a higher body mass index (BMI) prior to pregnancy (P < 0.01). Weight gain during pregnancy was higher in narcoleptic patients with cataplexy (P < 0.01). More patients with narcolepsy-cataplexy during pregnancy had impaired glucose metabolism and anaemia. Three patients experienced cataplexy during delivery. The rate of caesarean sections was higher in the narcolepsy-cataplexy group compared to the narcolepsy group (P < 0.05). The mean birth weight and gestational age of neonates were within the normal range and did not differ across groups. Neonatal care was affected adversely by symptoms of narcolepsy in 60.1% of those with narcolepsy during pregnancy. This study reports more obstetric complications in patients with narcolepsy-cataplexy during pregnancy; however, these were not severe. This group also had a higher BMI and higher incidence of impaired glucose metabolism during pregnancy. Caesarian section was conducted more frequently in narcolepsy-cataplexy patients, despite cataplexy being a rare event during delivery. Furthermore, symptoms of narcolepsy may render care of the infant more difficult.

[Cytomegalovirus disease in immunosuppressed patients with necrotizing pauci-immune glomerulonephritis]. / Enfermedad por citomegalovirus en los pacientes inmunodeprimidos por glomerulonefritis necrosante pauciinmune.

INTRODUCTION: Renal involvement due to necrotizing pauci-immune glomerulonephritis (PIGN) associated with small vessel vasculitis requires the use of immunosuppressive. Associated side effects include an increased risk of infectious processes, such as cytomegalovirus (CMV) disease; therefore, there are no recommendations on its management in the various clinical practice guidelines (CPG). OBJECTIVE: To study the incidence of CMV disease and its determinants. PATIENTS AND METHODS: Patients with histological diagnosis of necrotizing pauci-immune glomerulonephritis in the last 10 years, who were determined the viral load of CMV, analyzing the determinants of its occurrence. RESULTS: Forty-four biopsies were performed during the study period. Eleven patients (25%) developed CMV disease; all had received immunosuppressive treatment. Four (30.8%) died during admission. The determinants of CMV disease were age (for every 10 years OR: 3.0, 95% CI: 1.0-8.9, p = 0.012), and plasma albumin (for each g/L OR: 0.8, 95% CI: 0.6-1.0, p = 0.012). CONCLUSIONS: The incidence of CMV disease in immunocompromised patients due to PIGN is high, with high mortality. It would be necessary to include strategies in the CPGs to prevent it.

Psychosocial factors partially explain gender differences in health-related quality of life in heart failure patients.

AIMS: There is little information about the influence of gender on quality of life (QoL) in heart failure. The purpose of this study was to evaluate whether the health-related QoL gap between men and women can be explained by the interaction between psychosocial factors and clinical determinants in a real-word cohort of patients with chronic heart failure. METHODS AND RESULTS: We conducted a single-centre, observational, prospective cohort study of 1236 consecutive patients diagnosed with chronic heart failure recruited between 2004 and 2014. To assess QoL, we used the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Female gender was associated with worse global QoL compared to male gender (MLHFQ overall summary score: 49 ± 23 vs. 43 ± 24; P value <0.001, respectively) and similarly had poorer scores in physical and emotional dimensions but scored better on social dimension. In univariate models and in models adjusted for clinical determinants, female gender behaved as a predictor of worse global, physical and emotional QoL, and better social QoL compared with men. In models only including psychosocial determinants and in comprehensive models including all psychosocial and clinical factors, these differences according to gender were no longer significant. CONCLUSIONS: In this study, we have shown that the gap in health-related QoL between men and women with chronic heart failure can be partially explained by the interaction between biological and psychosocial factors. Biological factors are the main drivers of QoL in HF patients. However, the contribution of psychosocial factors is essential to definitively understand the role of gender in this field.

Narrative Review of Multidisciplinary Management of Central Nervous Involvement in Patients with HER2-Positive Metastatic Breast Cancer: Focus on Elderly Patients.

The tumor biology of human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) promotes the development of central nervous system (CNS) metastases, with 25% of patients with HER2-positive BC developing CNS metastases. Furthermore, the incidence of HER2-positive BC brain metastases has increased in the last decades, likely because of the improved survival with targeted therapies and better detection methods. Brain metastases are detrimental to quality of life and survival and represent a challenging clinical problem, particularly in elderly women, who comprise a substantial proportion of patients diagnosed with BC and often have comorbidities or an age-related decline in organ function. Treatment options for patients with BC brain metastases include surgical resection, whole-brain radiation therapy, stereotactic radiosurgery, chemotherapy, and targeted agents. Ideally, local and systemic treatment decisions should be made by a multidisciplinary team, with input from several specialties, based on an individualized prognostic classification. In elderly patients with BC, additional age-associated conditions, such as geriatric syndromes or comorbidities, and the physiologic changes associated with aging, may impact their ability to tolerate cancer therapy and should be considered in the treatment decision-making process. This review describes the treatment options for elderly patients with HER2-positive BC and brain metastases, focusing on the importance of multidisciplinary management, the different points of view from the distinct disciplines, and the role of oncogeriatric and palliative care in this vulnerable patient group.

Effect of Routine Invasive vs Conservative Strategy in Older Adults With Frailty and Non-ST-Segment Elevation Acute Myocardial Infarction: A Randomized Clinical Trial.

Importance: To our knowledge, no randomized clinical trial has compared the invasive and conservative strategies in frail, older patients with non-ST-segment elevation acute myocardial infarction (NSTEMI). Objective: To compare outcomes of invasive and conservative strategies in frail, older patients with NSTEMI at 1 year. Design, Setting, and Participants: This multicenter randomized clinical trial was conducted at 13 Spanish hospitals between July 7, 2017, and January 9, 2021, and included 167 older adult (≥70 years) patients with frailty (Clinical Frailty Scale score ≥4) and NSTEMI. Data analysis was performed from April 2022 to June 2022. Interventions: Patients were randomized to routine invasive (coronary angiography and revascularization if feasible; n = 84) or conservative (medical treatment with coronary angiography for recurrent ischemia; n = 83) strategy. Main Outcomes and Measures: The primary end point was the number of days alive and out of the hospital (DAOH) from discharge to 1 year. The coprimary end point was the composite of cardiac death, reinfarction, or postdischarge revascularization. Results: The study was prematurely stopped due to the COVID-19 pandemic when 95% of the calculated sample size had been enrolled. Among the 167 patients included, the mean (SD) age was 86 (5) years, and mean (SD) Clinical Frailty Scale score was 5 (1). While not statistically different, DAOH were about 1 month (28 days; 95% CI, -7 to 62) greater for patients managed conservatively (312 days; 95% CI, 289 to 335) vs patients managed invasively (284 days; 95% CI, 255 to 311; P = .12). A sensitivity analysis stratified by sex did not show differences. In addition, we found no differences in all-cause mortality (hazard ratio, 1.45; 95% CI, 0.74-2.85; P = .28). There was a 28-day shorter survival in the invasive vs conservatively managed group (95% CI, -63 to 7 days; restricted mean survival time analysis). Noncardiac reasons accounted for 56% of the readmissions. There were no differences in the number of readmissions or days spent in the hospital after discharge between groups. Neither were there differences in the coprimary end point of ischemic cardiac events (subdistribution hazard ratio, 0.92; 95% CI, 0.54-1.57; P = .78). Conclusions and Relevance: In this randomized clinical trial of NSTEMI in frail older patients, there was no benefit to a routine invasive strategy in DAOH during the first year. Based on these findings, a policy of medical management and watchful observation is recommended for older patients with frailty and NSTEMI. Trial Registration: ClinicalTrials.gov Identifier: NCT03208153.

Originator recombinant human follitropin alfa versus recombinant human follitropin alfa biosimilars in Spain: A cost-effectiveness analysis of assisted reproductive technology related to fresh embryo transfers.

This study compared the cost per live birth and cost-effectiveness of the originator recombinant human follicle-stimulating hormone follitropin alfa (r-hFSH-alfa) and r-hFSH-alfa biosimilars for ovarian stimulation prior to assisted reproductive technology treatment in Spain. A decision tree model was developed, comprising pregnancy and live birth for one treatment cycle with fresh embryo transfer. Clinical inputs were based on a recent meta-analysis by Chua et al. [4]. Cost inputs were extracted from publicly available Spanish sources. The costs per live birth were lower with originator r-hFSH-alfa (€18,138) versus r-hFSH-alfa biosimilars (€20,377). The incremental cost-effectiveness ratio was €7208 for originator r-hFSH-alfa versus biosimilars. Drug acquisition costs for originator r-hFSH-alfa represented 10.5% of total costs in the base case analysis, and 6.2% in a treatment cycle resulting in live birth with one fresh embryo transfer. Results from the sensitivity analyses confirmed the robustness of the findings.

[Components of geriatric assessment and therapeutic adherence in elderly patients with acute myocardial infarction]. / Componentes de la valoración geriátrica y adherencia terapéutica en el paciente anciano con infarto agudo de miocardio.

BACKGROUND AND OBJECTIVE: Poor therapeutic adherence after acute myocardial infarction (AMI) can lead to early serious complications. Information on the impact of geriatric assessment on adherence is scarce. The objective of this study was to analyze, in older patients with AMI, the impact of geriatric assessment on therapeutic adherence 12 months after admission. MATERIALS AND METHODS: A previous study randomized patients aged >75 years who had presented an AMI to a nursing health education program versus conventional management, evaluating the impact of this intervention on therapeutic adherence after 12 months. In-hospital geriatric assessment was performed. For this substudy, the adherence predictors were analyzed using binary logistic regression. Those patients who obtained adherence in the 4 tools were considered adherent: the Morisky-Green, Haynes-Sackett test, attendance at visits and correct withdrawal of drugs from the pharmacy. RESULTS: A total of 119 patients with a mean age of 82.2 years were included. At one year, a total of 42 patients (35.3%) were adherent. The predictors of poor adherence in the final model were male sex, worse glomerular filtration rate, cognitive impairment, nutritional risk, not living alone and not belonging to the intervention group. CONCLUSIONS: The data of this series show a low therapeutic adherence in the elderly after an AMI. Cognitive impairment or nutritional risk was significantly associated with poorer adherence, contrary to a nursing intervention, which highlights the importance of health education and supervision in high-risk patients.

Effect of weight change after renal transplantation on outcomes of graft survival.

BACKGROUND AND OBJECTIVE: After kidney transplantation, there is an overall increase in weight, which may increase the risk of chronic kidney disease (CKD) and graft loss. But, not all patients gain weight, and the impact on the graft of this different evolution has not been well studied. The objective was to determine the causes of this different evolution and its effect on the graft. PATIENTS AND METHODS: Retrospective single-center cohort study of 201 patients followed up after transplantation, analyzing the determinants of the variation in weight at one year using logistic regression, and its effect on graft survival at the end of follow-up using Cox regression. RESULTS: Globally, there was an average weight gain of 4.5 kg in the first year, but 26.6% lost weight. 37.2% increased their BMI, while 9.5% decreased it. The determinants of the different evolution of weight were age (OR for every 10 years: 0.6, p = 0.002), previous dialysis modality (ref. hemodialysis) (OR 0.3, p = 0.003), and BMI before transplantation (OR 0.9, p = 0.017). The different evolution of weight did not influence the final situation of the graft. The BMI at one year did influence as a continuous variable (HR 1.3, p = 0.003), and obesity, with a worse evolution (HR 7.0, p = 0.025). CONCLUSIONS: Although not all patients gain weight after kidney transplantation, the different evolution of weight does not influence graft survival.

Effectiveness of telemedicine in patients with heart failure according to frailty phenotypes: Insights from the iCOR randomised controlled trial.

BACKGROUND: The potential impact of telemedicine (TM) in the monitoring of patients with heart failure (HF) is still uncertain particularly in the frailest patients. The aim of this study was to define the efficacy of a TM-based managed care solution across different HF patient frailty phenotypes. METHODS: We performed a clustering analysis on the basis of 8 frailty-related dimensions to the HF-patients included in the 'insuficiència Cardíaca Optimització Remota' (iCOR) randomised study comparing TM vs. usual care (UC) in HF patients. The primary study endpoint was the incidence of a non-fatal HF event after 6 months of inclusion. The healthcare-related costs in each study group and cluster were also evaluated. The event rates of primary and secondary study endpoints were calculated for each cluster. Cox proportional-hazards regression models were used to evaluate the effect of cluster, treatment group and the interaction term cluster by treatment group on study endpoints. RESULTS: 5 different frailty phenotypes were identified. The positive effect of TM compared to UC strategy was consistent across all frailty phenotypes (p-value for interaction 0.711). The risk of experiencing a primary event was significantly lower in patients that underwent allocation to the TM arm compared to UC (p-value = 0.016). Ultimately, the healthcare costs were significantly reduced in patients allocated to the TM compared to UC in all 5 frailty phenotypes (all p-value < 0.05). CONCLUSIONS: Non-invasive TM-based follow-up tools are effective compared to UC follow-up in preventing HF events in the early post-discharge period, regardless of the 5 frailty phenotypes.

Safety and efficacy of ribociclib plus letrozole in patients with HR+, HER2- advanced breast cancer: Results from the Spanish sub-population of the phase 3b CompLEEment-1 trial.

BACKGROUND: Breast cancer is the most common malignancy and the second leading cause of cancer-related mortality in Spanish women. Ribociclib in combination with endocrine therapy (ET) has shown superiority in prolonging survival in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC) vs. ET alone. METHODS: CompLEEment-1 is a single-arm, open-label phase 3b trial evaluating ribociclib plus letrozole in a broad population of patients with HR+, HER2- ABC. The primary endpoints were safety and tolerability. Here we report data for Spanish patients enrolled in CompLEEment-1. RESULTS: A total of 526 patients were evaluated (median follow-up: 26.97 months). Baseline characteristics showed a diverse population with a median age of 54 years. At study entry, 56.5% of patients had visceral metastases and 8.7% had received prior chemotherapy for advanced disease. Rates of all-grade and Grade ≥3 adverse events (AEs) were 99.0% and 76.2%, respectively; 21.3% of patients experienced a serious AE, and 15.8% of AEs led to treatment discontinuation. AEs of special interest of neutropenia, increased alanine aminotransferase, increased aspartate aminotransferase and QTcF prolongation occurred in 77.8%, 14.8%, 11.4% and 4.0% of patients, respectively. Patients aged >70 years experienced increased rates of all-grade and Grade ≥3 neutropenia and anemia. Efficacy results were consistent with the global study. CONCLUSIONS: Results from Spanish patients enrolled in CompLEEment-1 are consistent with global data showing efficacy and a manageable safety profile for ribociclib plus letrozole treatment in patients with HR+, HER2- ABC, including populations of interest (NCT02941926). TRIAL REGISTRATION: ClinicalTrials.gov NCT02941926.

Association between ultrapocessed food and chronic kidney disease.

The modern diet is closely linked to the consumption of processed foods, causing an increase in the intake of salt, simple sugars, phosphorus and added potassium. This excess intake is associated with an increased risk of obesity, diabetes, hypertension and chronic kidney disease (CKD). CKD, which according to data from the ENRICA study affects 15% of the population, magnifies its impact due to the higher prevalence of diabetes and hypertension and due to limitations in the management of sodium and phosphorus. The intake of these products far exceeds the established recommendations, assuming 72% of total sodium, 25%-35% of phosphorus, 12%-18% of potassium and exceeding 10% of the caloric intake in simple sugars. Measures are necessary to reduce their contribution through nutritional advice, labeling review, education campaigns on healthy habits, fees and institutional actions that involve food safety agencies, industry, distribution and scientific societies.

We lose ground: Global assessment of land subsidence impact extent.

Depletion of groundwater aquifers along with all of the associated quality and quantity problems which affect profitability of direct agricultural and urban users and linked groundwater-ecosystems have been recognized globally. During recent years, attention has been devoted to land subsidence-the loss of land elevation that occurs in areas with certain geological characteristics associated with aquifer exploitation. Despite the large socioeconomic impacts of land subsidence most of these effects are still not well analyzed and not properly recognized and quantified globally. In this paper we developed a land subsidence impact extent (LSIE) index that is based on 10 land subsidence attributes, and applied it to 113 sites located around the world with reported land subsidence effects. We used statistical means to map physical, human, and policy variables to the regions affected by land subsidence and quantified their impact on the index. Our main findings suggest that LSIE increases between 0.1 and 6.5% by changes in natural processes, regulatory policy interventions, and groundwater usage, while holding all other variables unchanged. Effectiveness of regulatory policy interventions varies depending on the lithology of the aquifer system, in particular its stiffness. Our findings suggest also that developing countries are more prone to land subsidence due to lower performance of their existing water governance and institutions.

Can an individualized adherence education program delivered by nurses improve therapeutic adherence in elderly people with acute myocardial infarction?: A randomized controlled study.

BACKGROUND: The ageing of the population is leading to an increase in the number of elderly patients with acute myocardial infarction. These patients are at higher risk for complications and poor medication adherence, which in turn are associated with higher healthcare resource expenditures. Nursing programmes might help to improve adherence in these complex patients. OBJECTIVE: The objective of this study was to assess the impact of a nursing intervention on therapeutic adherence in elderly patients after myocardial infarction compared to a control group. DESIGN: A single-blind, randomized controlled trial. SETTINGS: Heart disease institute of a tertiary care hospital. PARTICIPANTS: Patients aged ≥75 years with myocardial infarction undergoing percutaneous coronary intervention. METHODS: A comprehensive geriatric assessment was performed during the admission in all patients (N=143). Patients were randomly allocated to a nursing intervention group (n=68) or a usual care group (n=75). In patients from the intervention group, a nursing intervention programme was performed 3 months after admission based on education support and patient monitoring to improve therapeutic adherence. The main outcome measured was 12-months therapeutic adherence, as defined by a combination of measurement tools (Morisky-Green and Hayness-Sacket scales, attendance at visits and withdrawal of medication from the pharmacy). Therapeutic adherence was assessed by nurses blinded to the assignment group. RESULTS: The mean age was 82.2 years. The proportion of comorbidities was significant (diabetes mellitus 51/143 (35.7%), hypertension 110/143 (76.9%), prior stroke 22/143 (15.4%)). Likewise, the proportion of geriatric syndromes was noticeable (frailty 26/143 (18.2%), risk of malnutrition 38/143 (26.6%), cognitive impairment 28/143 (19.6%)). Most patients (92.3%) had a low educational level. A total of 119 patients achieved 12-month assessment adherence. Among these patients, the proportions of adherence were as follows: Morisky-Green test: 76/119 (63.9%), Haynes-Sackett test 99/119 (83.2%), medical visits compliance 95/119 (79.8%), and correct acquisition of drugs in the pharmacy 74/119 (62.2%). A total of 42/119 patients (35.3%) were adherent as defined by the combination of the 4 measures. Therapeutic adherence at 12 months was achieved in a significantly higher proportion of patients from the nursing intervention group (51.9% vs 21.5%, p<0.001). CONCLUSION: A significant proportion of elderly patients with myocardial infarction were non-adherent at 12 months. The proportion of adherent patients was highly variable according to the different tools used. A structured nursing intervention was independently associated with a higher adherence rate, as assessed by a multidimensional measurement, in this subset of complex high-risk elderly patients with myocardial infarction.
