External urology consultation quality at a third-level public hospital in Mexico.

INTRODUCTION: Patient satisfaction is the degree of conformity with the healthcare they receive. It is real evidence and one of the most important factors in determining the effectiveness and quality of healthcare systems. OBJECTIVE: To identify the quality of care in the Urology outpatient department of a third-level hospital. MATERIALS AND METHODS: The NHS (National Health Service) 2018 quality of care questionnaire with 11 sections, 133 items, and duration of approximately 25min was randomly administered to 250 patients attending Urology outpatients at a third-level public hospital in Mexico. RESULTS: According to responses, 92% (n=230) knew the reason for the consultation. 64.8% (n=162) had a consultation with the same physician by whom they were initially seen. The longest reported hospital wait time before being seen was more than 2h in 29.6% (n=74). As for consultation time, 212 patients responded and the duration was 11-20min in 52.8% (n=112). Finally, 33.2% (n=83) considered the quality of service to be good. CONCLUSIONS: The use of the NHS 2018 survey in the Urology service at a third-level public hospital in Mexico is feasible, since we managed to obtain a significant and continuous improvement in all its indicators which is satisfactory for all.

Background and objective Physical exercise increases functional capacity in older adults, helping to prevent or delay dependence. This study evaluates the impact of a multicomponent physical exercise intervention based on the Vivifrail program, conducted in a primary care center over two years coinciding with the COVID pandemic. Subjects and methods Descriptive longitudinal design with before-after comparison without control group. Participants were older than 65 years old with functional impairment measured by execution test, enrolled in the El Palo Health Center, Málaga. The intervention consists of two weekly group sessions of physical exercise guided by a monitor, according to the Vivifrail program. Variables: Barthel Index, Gait Speed, Vivifrail Category, Quality of Life (EuroQol 5-D [EQ-5D]), use of walking aids, number of falls in the previous year. Measurements: baseline, second (one year) and final (two years). Analysis of the Kruskal-Wallis test, significance level 0.05. Results Twenty patients were evaluated. Between the first and second evaluation, we observed a significant modification in the use of walking aids (p 0.01) and Vivifrail categories: from an initial B category, 50% remained, 25% moved to A, 16.7% to C2 and 8.3% to D (p 0.048). In the analysis of the baseline-final evaluation, we found a statistically significant improvement in quality of life measured by EQ-5D (mean increase of 24 points in today's quality of life measurement, EQ-5D thermometer, with 95% CI (9.6-38.3), p 0.004) and Vivifrail category (n=10) with 60% remaining in category B and 40% moving to D (autonomous) (p<0.0001). There was a trend towards improvement in gait speed, daily walking time, and number of falls, but without reaching statistical significance.

A multidimensional approach to the resilience in older adults despite COVID-19.

Researchers have mainly focused on aging risk factors and COVID-19 consequences. However, older adults have proved their ability to overcome adversities along their life. Resilience is a protective variable that dampens the impact of stress. Based on MacLeod's et al. (2016) approach, we aimed to analyze the relationship between older adults' resilience and COVID-19 related-stressors as well as their physical, mental, and social characteristics. Eight hundred eighty-nine people aged 60 and over participated in this study. Older participants, women, having better perceived health and not losing a loved one because of the virus were associated with more resilience. Moreover, higher levels of gratitude, personal growth, life purpose and lower levels of depression were associated with greater scores in resilience. This study offers a change of perspective in which aging is perceived from a positive viewpoint by focusing on easily accessible resources that may help older adults to cope with adverse situations.

Understanding enhanced rotational dynamics of active probes in rod suspensions.

Active Brownian particles (APs) have recently been shown to exhibit enhanced rotational diffusion (ERD) in complex fluids. Here, we experimentally observe ERD and numerically corroborate its microscopic origin for a quasi-two-dimensional suspension of colloidal rods. At high density, the rods form small rafts, wherein they perform small-amplitude, high-frequency longitudinal displacements. Activity couples AP-rod contacts to reorientation, with the variance therein leading to ERD. This is captured by a local, rather than a global relaxation time, as used in previous phenomenological modeling. Our result should prove relevant to the microrheological characterization of complex fluids and furthering our understanding of the dynamics of microorganisms in such media.

Manufacture of magnesium-fortified Chihuahua cheese.

The aim of this study was to manufacture magnesium-fortified Chihuahua cheese and to evaluate the effect of magnesium fortification on quality parameters. Addition of magnesium chloride to milk during pasteurization (5.44, 10.80, 16.40, 22.00, and 25.20 g of MgCl2·6H2O/L of milk) resulted in cheese with increased magnesium content, proportional to the amount of magnesium added (up to 2,957.13 mg of Mg/kg of cheese). As magnesium content increased, coagulation time and moisture content also increased, whereas calcium content decreased. Higher levels of magnesium fortification (16.40 g of MgCl2·6H2O/L of milk or more) induced the development of bitter-acid flavors and softer texture. Addition of 10.80 g of MgCl2·6H2O/L to milk resulted in Chihuahua cheese that meets regulatory standards and possesses physicochemical and sensory characteristics similar to those of nonfortified Chihuahua cheese. Under this milk fortification level, the manufactured cheese is able to provide 148.4 mg of magnesium per day (35% of the recommended daily intake of magnesium for adult males and 46% for adult females) assuming 3 portions (28 g each) are consumed.

Chemical interactions among caseins during rennet coagulation of milk.

Rennet milk curds were prepared under 4 different temperature and acidity conditions. The development of different types of inter-protein chemical bonds (disulfide, hydrophobic, electrostatic, hydrogen, and calcium bridges) was monitored for 60 min after curd cutting. Hydrophobic inter-protein interactions originally present in casein micelles in milk were substituted by electrostatic, hydrogen, and calcium bonds throughout the curd curing period. Disulfide bonds were not disturbed by the experimental conditions employed in the study, remaining at a constant level in all studied treatments. Acidification of curds increased the availability of soluble ionic calcium, increasing the relative proportion of calcium bridges at the expense of electrostatic-hydrogen bonds. Although pH defined the nature of the interactions established among proteins in curd, temperature modified the rate at which such bonds were formed.

Nutritional management and clinical outcome of critically ill patients with COVID-19: A retrospective study in a tertiary hospital.

BACKGROUND & AIMS: Severe COVID-19 infection is characterized by an inflammatory response and lung injury that can evolve into an acute respiratory distress syndrome that needs support treatment in intensive care unit. Nutritional treatment is an important component of the management of critically ill patients and should be started in the first 48 h of ICU admission to avoid malnutrition. This study describes the characteristics of the patients treated in a tertiary hospital in Madrid during the months of March-May 2020 (first wave), the medical nutrition treatment employed and its influence in the clinical outcome of these patients. METHODS: This is a retrospective study including COVID-19 patients admitted in ICU that needed medical nutrition treatment (MNT). Collected variables included sex, age, BMI, underlying diseases, time from hospitalisation to ICU admission, type of respiratory support (invasive mechanical ventilation (IMV) or high flow nasal cannula (HFNC) or non-invasive ventilation (non-IMV)), caloric and protein requirements (25 kcal/kg adjusted body weight (ABW), 1.3 g/kg ABW/day), MNT type (enteral nutrition (EN), parenteral nutrition (PN), mixed EN + PN), total calories (including propofol) and proteins administered, percentage of caloric and protein goal in ICU day 4th and 7th, metabolic complications, acute kidney failure (AKF), length of stay (LOS) and mortality. Data are expressed as mean ± SD, median (IQR) or frequencies. Statistical analysis was performed with the IBM SPSS Statistics for Windows, Version 25.0. p < 0.05 were considered statistically significant. RESULTS: A total of 176 patients were included (72.7% male), 60.1 ± 13.5 years, BMI 29.9 ± 5.4 kg/m2. Underlying diseases included 47.4% overweight, 39.8% obesity, 49.1% hypertension, 41.4% dyslipidaemia. 88.6% of patients needed IMV, 89.1% prone position, 2.9% ECMO. Time to ICU admission: 2 (4.75) days. Estimated caloric and protein requirements were 1775 ± 202 kcal and 92.4 ± 10.3 g. Calories and proteins administered at days 4th and 7th were 1425 ± 577 kcal and 66 ± 26 g and 1574 ± 555 and 74 ± 37, respectively. Most of the patients received PN (alone or complementary to EN) to cover nutritional requirements (82.4% at day 4th and 77.9% at day 7th). IVM patients received more calories and proteins during the first week of ICU admission. Complications included 77.8% hyperglycaemia, 13.2% hypoglycaemia, 83.8% hypertriglyceridemia, and 35.1% AKF. ICU LOS was 20.5 (26) days. The mortality rate was 36.4%. CONCLUSIONS: In our series, the majority of patients reached energy and protein requirements in the first week of ICU admission due to the use of PN (total or complementary to EN). Patients with HFNC or non-IMV may be at risk of malnutrition if total or complementary PN to oral diet/ONS/tube feeding is not used to cover nutritional requirements. Therefore, if EN is not possible or insufficient, PN can be safely used in critically ill patients with COVID-19 with a close monitoring of metabolic complications.

Dinámica de elección en humanos: efectos de la modalidad de respuesta / Dynamics of Choice in Humans: Effects of Response Modality

The main aim of the study was to assess the effects of varying response modality in the human allocation of operant responses to different reinforcement sources using a rapidly changing environment procedure. A total of nine undergraduate students participated. In each session, participants were presented with seven independent concurrent variable interval schedules of reinforcement in an irregular order. Individual schedules lasted for the delivery of five reinforcers. In Experiment 1, six students were randomly assigned to two conditions (BO and MT). In the BO condition, participants pressed buttons on the screen to earn points. In the MT condition, participants tracked and pressed moving targets that changed position every 2000 ms. Results showed that sensitivity to reinforcement developed just for the BO condition. A second Experiment was conducted, having three participants, and using the MT condition only. The rate of target position change parameter was modified to 300 milliseconds. Under those conditions, the development of sensitivity to reinforcement was observed. However, variable performances were found. It is concluded that response modality can affect the development of sensitivity if response requisites to obtain reinforcement depend on the way the response modality is arranged (AU)

Psychological well-being among older adults during the COVID-19 outbreak: a comparative study of the young-old and the old-old adults.

The COVID-19 outbreak could be considered as an uncontrollable stressful life event. Lockdown measures have provoked a disruption of daily life with a great impact over older adults' health and well-being. Nevertheless, eudaimonic well-being plays a protective role in confronting adverse circumstances, such as the COVID-19 situation. This study aims to assess the association between age and psychological well-being (personal growth and purpose in life). Young-old (60-70 years) and old-old (71-80 years) community-dwelling Spaniards (N = 878) completed a survey and reported on their sociodemographic characteristics and their levels of health, COVID-19 stress-related, appraisal, and personal resources. Old-old did not evidence poorer psychological well-being than young-old. Age has only a negative impact on personal growth. The results also suggest that the nature of the COVID-19 impact (except for the loss of a loved one) may not be as relevant for the older adults' well-being as their appraisals and personal resources for managing COVID-related problems. In addition, these results suggest that some sociodemographic and health-related variables have an impact on older adults' well-being. Thus, perceived-health, family functioning, resilience, gratitude, and acceptance had significant associations with both personal growth and purpose in life. Efforts to address older adults' psychological well-being focusing on older adults' personal resources should be considered.

Mass transfer modeling of the antioxidant extraction of roselle flower (Hibiscus sabdariffa).

The aim of this study was to analyze the equilibrium and dynamic periods for mass transfer during the antioxidant solid-liquid extraction of dry roselle flower (Hibiscus sabdariffa). Extraction kinetics for total phenolic compounds (TPC), total flavonoids (TFL) and total antioxidant capacity (TAC) were obtained at different temperatures (50, 60, 70 or 80 °C) and solvent-to-product mass ratios (100:1, 200:1 or 300:1 g/g) under stirring (220-230 rpm). An analytical solution for unsteady-state mass transfer based on Fick's second law of diffusion was used to mathematically describe solid-liquid extraction curves and for the simultaneous estimation of diffusion coefficients and the final amount of extracted bioactive compounds, which were further related to experimental conditions by a second order model. The amount of extracted bioactive compounds at equilibrium were in the ranges of 30.8-89.8 g GAE/kg d.m. for TPC (0.154-0.373 g GAE/L extract), 40.0-131.6 g catechin/kg d.m. for TFC (0.269-0.559 g catechin/L extract) and 37.5-227.0 g trolox/kg d.m. for TAC (0.346-0.865 g trolox/L extract). On the other hand, diffusion coefficients for TPC, TFC and TAC were in the ranges of 0.72-2.66 × 10-11, 0.25-2.37 × 10-11 and 1.19-5.79 × 10-11 m2/s, respectively.

Development and assessment of the content validity of the professional good practices scale in nursing homes.

Recent approaches in the care of older people have led to a greater emphasis on good practices to prevent elder abuse. The instruments assessing good practices are very limited, and those focused on elder abuse have rarely considered subtle forms, especially in institutional settings. The aim of this study was to develop and assess the content validity of a good practices scale for professionals working in nursing homes. An extensive literature review of the tools assessing professionals' good-bad practices towards older people was conducted. A preliminary scale based on Kayser-Jones' (1990) [Old, Alone and Neglected: Care of the Aged in Scotland and the United States. Berkeley, CA: University of California Press] types of abuse was developed, including four subscales: Personalization, Humanization, Absence of Infantilization, and Absence of Victimization. Content validity was analyzed through a panel of eight experts. Rovinelli and Hambleton's index of item-objective congruence was used to analyze the items' inclusiveness in the assigned subscale to establish their representativeness. Items' relevance and clarity were analyzed using the paired comparison method. The final version of the scale included 56 items, with appropriate levels of item objective-congruence, relevance, and clarity. This instrument will allow professionals to detect and develop awareness and intervention programs that aim to promote good practices in nursing homes.

Direct costs of a home parenteral nutrition programme.

BACKGROUND & AIMS: Home parenteral nutrition (HPN) is a lifesaving treatment for people with chronic intestinal failure and its cost has been reported to be very high. The purpose of the present paper was to study the direct healthcare and non-healthcare costs associated with the HPN programme managed by a tertiary hospital. METHODS: Observational, retrospective study of all adult patients on HPN from 11.1.2014 to 10.31.2015 treated at Gregorio Marañón University Hospital (Madrid, Spain). An economic evaluation was undertaken to calculate the direct healthcare (HPN provision, outpatient monitoring and management of complications) and non-healthcare costs (transportation process) of the HPN programme. The variables were collected from medical records, the dispensary and the hospital's financial services. The unit costs were taken from official price lists. RESULTS: Thirty-two patients met the inclusion criteria. Total direct healthcare and non-healthcare costs amounted to €13,363.53 per patient (€124.02 per patient per day). The direct healthcare costs accounted for 98.32% of overall costs, while the non-healthcare costs accounted for the remaining 1.68%. HPN provision accounted for the majority of the costs (74.25%), followed by management of complications (21.85%) and outpatient monitoring (2.23%). CONCLUSIONS: The direct healthcare costs accounted for the majority of HPN expenditure, specifically HPN provision was the category with the highest percentage.

Breastfeeding avoidance following psychological intimate partner violence during pregnancy: a cohort study and multivariate analysis.

OBJECTIVE: To evaluate if the experience of psychological intimate partner violence (IPV) adversely affects breastfeeding rates. DESIGN: A cohort study. SETTING: Maternities in 15 public hospitals, drawn using cluster sampling of obstetric services in Andalusia, Spain. POPULATION: A total of 779 consecutive mothers receiving antenatal care including ultrasound and giving birth during February-June 2010. METHODS: Trained midwives gathered IPV data using the Index of Spouse Abuse validated in the Spanish language (score ranges: 0-100, higher scores reflect more severe IPV; cut-off: psychological IPV = 25). Sociodemographic data including lack of kin support, and obstetric and neonatal outcomes were collected. Multivariate logistic regression estimated adjusted odds ratios (aOR), with 95% confidence intervals (CI), of the relationship between psychological IPV and breastfeeding, controlling for sociodemographic characteristics and obstetric complications. MAIN OUTCOME MEASURE: Breastfeeding avoidance defined as lack of breastfeeding or pumping of breast milk to feed the new baby in the immediate post-partum period. RESULTS: Response rate was 92.2%. A total of 70% (n = 545) of women initiated breastfeeding. Psychological IPV, reported by 21.0% (n = 151), increased the odds of breastfeeding avoidance (aOR = 2.0; 95% CI = 1.2-3.3) adjusting for the presence of obstetric complications (aOR = 1.6; 95% CI = 1.0-2.4). CONCLUSIONS: Mothers with psychological IPV avoid breastfeeding. Clinicians should be aware of the risks to infant arising from this deficiency due to IPV in pregnancy. TWEETABLE ABSTRACT: Psychological intimate partner violence, reported by one in five mothers in this study, on average doubles the avoidance of breastfeeding.

Exposure to Radioactive Emanations of Medical Personnel in Percutaneous Nephrolithotomy.

The use of radioactive emanations has been of great importance for the performance of endourology procedures, such as percutaneous nephrolithotomy (NLP). The damage to health caused by radiation has been a sensitive issue. The objective of this work was to determine the dose received by the surgeon during NLP and the total dose generated by the fluoroscope. A cross-sectional study was conducted with data from a cohort study with a duration of 18 months that included 101 patients. Radiation was measured with dosimeter during the last 6 months. During the last 6 months of the study, 34 patients were submitted to surgery. The average age was 47 years. Average fluoroscopy time was 58.3 second (24-122 seconds) in both male and female groups, with 57.16 seconds and 58.95 seconds per case, respectively (P = .6). Radiation emitted during 6 months for the 34 patients was 330.5 mGy. The total radiation measured by the dosimeter was 1 mSv, which is equivalent to 0.3% of the total radiation applied during the procedures. Doses measured by the dosimeter on the surgeon were within the recommended annual doses although dose received by the hands exceeds the authorized limits (500 mSv/y).

Use of microbial models to evaluate the effect of UV-C light and trans-cinnamaldehyde on the native microbial load of grapefruit (Citrus × paradisi) juice.

The aim of this research was to evaluate the storage stability (5 °C), and microbial modeling, of Rubi red grapefruit (Citrus × paradisi) juice treated with ultraviolet-C (UV-C) light (0, 10 and 20 min), alone or in combination with trans-cinnamaldehyde (trans-CAH) (0, 25 and 50 µg/mL). A 32 factorial design was used and data modeled with the Weibull, Modified Gompertz and Logistic models. A response surface model was used to evaluate the effect of modeling parameters for suggesting the optimum treatment conditions. Treated and some untreated juice lasted up to 9 days without physicochemical and microbial changes. At the higher combination of UV-C light and trans-CAH, the microbial load of grapefruit juice was maintained below 100 CFU/mL up to 15 days. For mesophiles, the three predictive models indicated that the parameters n and Nmax decreased and the parameters λ and tc increased as the combination of UV-C light and trans-CAH increased. The response surface modeling of the parameters obtained by the predictive models showed acceptable correlation for mesophiles (R2 = 0.815-0.977) but not for yeasts (R2 = 0.618-0.815). The three predictive models showed that, the concentration of trans-CAH had more effect on stopping the microbial growth than the UV-C light treatment.

Effect of Chronic Administration of Resveratrol on Cognitive Performance during Aging Process in Rats.

The increase in the elderly population has generated concern to meet health demands. The research efforts to elucidate the mechanisms of damage associated with aging have also been significantly increased, especially in order to avoid the reduction of the cognitive abilities in geriatric patients, resulting from the damage generated mainly at the level of the hippocampus during old age. At present, many studies describe resveratrol as an antiaging component. There are reports that it can activate the Sirt1 gene related to antiaging, emulating the effects obtained by caloric restriction in rodents. The aim of the study was to evaluate the effect of chronic administration of resveratrol (10 mg/kg) on cognitive performance in behavioral tests after 8 months of treatment and on the preservation of cerebral integrity in the cytoarchitecture of regions CA1 and CA2. Results showed that the cytoarchitecture of the CA1 and CA2 regions in the hippocampus retained their integrity over time in rats treated with resveratrol, and the behavioral test performed revealed that chronic resveratrol administration for 8 months showed improvements in cognitive performance. The results indicate that resveratrol may exhibit therapeutic potential for age-related conditions.

Antioxidant characteristics of extracts of Hibiscus sabdariffa calyces encapsulated with mesquite gum.

This study compared the stability of extracts of H. sabdariffa calyces microencapsulated with different concentrations of mesquite gum during storage. Dry Roselle calyces were mixed with 50:50 (v/v) ethanol:water solution to obtain 18°Bx concentrate. This Roselle extract concentrate was mixed with purified mesquite gum (100:1-100:5 v/w). The Roselle extract concentrate-gum (RECG) was spray dried at inlet and outlet temperatures of 180 ± 2 and 104 ± 2.3 °C, respectively, at an air flow rate of 38 m3/h. Encapsulated Roselle powders (ERP) were analyzed for moisture content, total monomeric anthocyanins (differential pH), phenolic compounds (Folin and Ciocalteu method), antioxidant capacity (ABTS), and color parameters ([Formula: see text], and [Formula: see text]) after 5 weeks and 1 year of storage. Sorption properties (isotherms) and micrographs of powders were also obtained. The average yield of RECG powders was 15.27 ± 0.81 g/100 mL. During storage, ERP showed average values of phenolic compounds, antioxidant capacity, and anthocyanins of 3.43 ± 0.25 g gallic acid equivalents/100 g, 9.34 ± 1.4 g Trolox equivalents/100 g, and 318.7 ± 20.6 mg cyanidin-O-glycoside/100 g, respectively. Color parameters remained constant along the storage time.

HIV continuum of care in Europe and Central Asia.

OBJECTIVES: The European Centre for Disease Prevention and Control (ECDC) supports countries to monitor progress in their response to the HIV epidemic. In line with these monitoring responsibilities, we assess how, and to what extent, the continuum of care is being measured across countries. METHODS: The ECDC sent out questionnaires to 55 countries in Europe and Central Asia in 2014. Nominated country representatives were questioned on how they defined and measured six elements of the continuum. We present our results using three previously described frameworks [breakpoints; Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets; diagnosis and treatment quadrant]. RESULTS: Forty countries provided data for at least one element of the continuum. Countries reported most frequently on the number of people diagnosed with HIV infection (37; 93%), and on the number in receipt of antiretroviral therapy (ART) (35; 88%). There was little consensus across countries in their approach to defining linkage to, and retention in, care. The most common breakpoint (>19% reduction between two adjacent elements) related to the estimated number of people living with HIV who were diagnosed (18 of 23; 78%). CONCLUSIONS: We present continuum data from multiple countries that provide both a snapshot of care provision and a baseline against which changes over time in care provision across Europe and Central Asia may be measured. To better inform HIV testing and treatment programmes, standard data collection approaches and definitions across the HIV continuum of care are needed. If countries wish to ensure an unbroken HIV continuum of care, people living with HIV need to be diagnosed promptly, and ART needs to be offered to all those diagnosed.
