Association between anxiety and frailty in postmenopausal women.

OBJECTIVE: To explore the association between anxiety and frailty in community-dwelling postmenopausal women. METHODS: This was a cross-sectional study in which 390 postmenopausal women (aged 60-83 years) who were attending a comprehensive care program were surveyed between January 2018 and February 2020. Each participant was administered a validated Spanish version of the Hospital Anxiety and Depression Scale (HADS) to assess their anxiety status. Those scoring 8 or higher on the anxiety subscale of the HADS were indicative of anxiety. The assessment of frailty utilized the Fried's phenotype, with a diagnosis of frailty established if the participant met at least three out of the five criteria. Factors associated with frailty were analyzed using multivariate logistic regression. RESULTS: The mean age of participants was 70.08 years, with an average of 12.58 ± 3.19 years since menopause. Frailty was diagnosed in 43.85% of the total series, while anxiety was present in 41.08%, rising to 69.59% in participants with frailty. Neither body mass index, years since menopause, educational level, economic status, nor smoking habit demonstrated significant associations with frailty. Upon multivariate analysis, anxiety (OR 8.56), multimorbidity (OR 2.18), and age (OR 2.73) emerged as independently associated with frailty (p < .001, p = .005, and p < .001, respectively). CONCLUSIONS: Among postmenopausal women with frailty, anxiety was detected in over two thirds of cases and was independently associated with frailty. This underscores the relevance of implementing anxiety screening in comprehensive care programs for postmenopausal women, with the goal of improving frailty through anxiety diagnosis and treatment.

Long-Term Effects of Microfiltered Seawater and Resistance Training with Elastic Bands on Hepatic Parameters, Inflammation, Oxidative Stress, and Blood Pressure of Older Women: A 32-Week, Double-Blinded, Randomized, Placebo-Controlled Trial.

The bulk of research on microfiltered seawater (SW) is based on its short-term effects. However, the long-term physiological adaptations to combining SW and resistance training (RT) are unknown. This study aimed to analyse the impact of an RT program using elastic bands combined with SW intake on hepatic biomarkers, inflammation, oxidative stress, and blood pressure in post-menopausal women. Ninety-three women voluntarily participated (age: 70 ± 6.26 years; body mass index: 22.05 ± 3.20 kg/m2; Up-and-Go Test: 6.66 ± 1.01 s). RT consisted of six exercises (32 weeks, 2 days/week). Nonsignificant differences were reported for hepatic biomarkers except for a reduction in glutamic-pyruvic transaminase (GPT) in both RT groups (RT + SW: p = 0.003, ES = 0.51; RT + Placebo: p = 0.012, ES = 0.36). Concerning oxidative stress, vitamin D increased significantly in RT + SW (p = 0.008, ES = 0.25). Regarding inflammation, interleukin 6 significantly decreased (p = 0.003, ES = 0.69) in RT + SW. Finally, systolic blood pressure significantly decreased in both RT groups (RT + placebo: p < 0.001, ES = 0.79; RT + SW: p < 0.001, ES = 0.71) as did diastolic blood pressure in both SW groups (RT + SW: p = 0.002, ES = 0.51; CON + SW: p = 0.028, ES = 0.50). Therefore, RT + SW or SW alone are safe strategies in the long term with no influences on hepatic and oxidative stress biomarkers. Additionally, SW in combination with RT positively influences vitamin D levels, inflammation, and blood pressure in older women.

Multicomponent and power training with elastic bands improve metabolic and inflammatory parameters, body composition and anthropometry, and physical function in older women with metabolic syndrome: A 20-week randomized, controlled trial.

PURPOSE: This study aimed to explore the effects of 20 weeks of multicomponent or power training with elastic bands (EBs) on metabolic and inflammatory blood parameters, body composition, anthropometry, and physical function in older women with metabolic syndrome (MS). METHODS: Ninety participants were randomly assigned to a multicomponent (MCG; n = 30), power (PG; n = 30), or a control group (CG; n = 30). The MCG performed balance, slow-speed strength, and aerobic training, twice per week. The PG completed a high-speed resistance training program twice per week, composed of three to four sets of ten repetitions of six overall body exercises at a perceived rating of effort for the first repetition of 3-4 on the OMNI-Resistance Exercise Scale EB. MS-related variables (glucose, triglycerides, and waist circumference) and cardiometabolic risk factors (high-density lipoprotein [HDL], glycosylated hemoglobin, total cholesterol, low-density lipoprotein cholesterol [LDL], C-reactive protein, and anthropometric profile) were assessed. Physical function was evaluated through balance, strength, and mobility tests. RESULTS: An analysis of variance revealed that both training groups similarly improved most glycemic and lipidic profile parameters (p ≤ 0.006; d ≥ 0.46), body composition and anthropometry (p < 0.001; d ≥ 0.41), and physical function (p ≤ 0.005; d ≥ 0.69). Opposed to the PG, the MCG improved balance (p < 0.001; d = 0.96) and decreased the inflammatory status by downregulating C-reactive protein (p = 0.003; d = 0.47). On the other hand, the PG exhibited improvements in handgrip strength (p = 0.006; d = 0.48), while the MCG did not. CONCLUSION: Therefore, multicomponent and power training with EBs are plausible strategies for improving the cardiometabolic health status and physical function in older women with MS.

Quality of life in sarcopenia measured with the SarQoL questionnaire: A meta-analysis of individual patient data.

Age-related sarcopenia, resulting from a gradual loss in skeletal muscle mass and strength, is pivotal to the increased prevalence of functional limitation among the older adult community. The purpose of this meta-analysis of individual patient data is to investigate the difference in health-related quality of life between sarcopenic individuals and those without the condition using the Sarcopenia Quality of Life (SarQoL) questionnaire. A protocol was published on PROSPERO. Multiple databases and the grey literature were searched until March 2023 for studies reporting quality of life assessed with the SarQoL for patients with and without sarcopenia. Two researchers conducted the systematic review independently. A two-stage meta-analysis was performed. First, crude (mean difference) and adjusted (beta coefficient) effect sizes were calculated within each database; then, a random effect meta-analysis was applied to pool them. Heterogeneity was measured using the Q-test and I2 value. Subgroup analyses were performed to investigate the source of potential heterogeneity. The strength of evidence of this association was assessed using GRADE. From the 413 studies identified, 32 were eventually included, of which 10 were unpublished data studies. Sarcopenic participants displayed significantly reduced health-related quality of life compared with non-sarcopenic individuals (mean difference = -12.32; 95 % CI = [-15.27; -9.37]). The model revealed significant heterogeneity. Subgroup analyses revealed a substantial impact of regions, clinical settings, and diagnostic criteria on the difference in health-related quality of life between sarcopenic and non-sarcopenic individuals. The level of evidence was moderate. This meta-analysis of individual patient data suggested that sarcopenia is associated with lower health-related quality of life measured with SarQoL.

Sarcopenic Obesity in Community-Dwelling Spanish Adults Older than 65 Years.

Sarcopenic obesity (SO) is diagnosed when sarcopenia and obesity coexist in patients. The objective of this study was to determine the prevalence of SO under different diagnostic criteria in community-dwelling Spanish adults aged over 65 years residing in Valencia (Spain). The research was conducted as an observational and cross-sectional study with a sample size of 202 subjects. To diagnose sarcopenia, we used the tests proposed by the European Working Group on Sarcopenia in Older People in 2019 (EWGSOP2): SARC-F, grip strength, sit-to-stand, gait speed, Appendicular Skeletal Muscle Mass (ASMM), and Short Physical Performance Battery (SPPB). For obesity diagnosis, we used body mass index (BMI), waist circumference (WC), total body fat percentage (%TBF), and tricipital skinfold (TS). The prevalence of SO was 16.5% in women and 29% in men, according to any of the diagnostic criteria used to determine obesity. A higher proportion of SO was observed as age increased in both groups, although no significant differences were found. Most values obtained in tests related to SO diagnosis were worse in the group affected by the disease; however, there were two exceptions related to the amount of ASMM. In total, 18.8% of the participants presented SO according to any diagnostic criteria related to obesity. Our results suggest significant differences in the number of SO cases depending on diagnostic criteria used to determine the participants' obesity. BMI, WC, and TBF% were shown as principal variables to be included in obesity diagnosis within the SO construct. These findings underscore the need to unify criteria to standardize the diagnosis of SO in the global population.

Predictive potential of SARS-CoV-2 RNA concentration in wastewater to assess the dynamics of COVID-19 clinical outcomes and infections.

Coronavirus disease 2019 - caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) -, has triggered a worldwide pandemic resulting in 665 million infections and over 6.5 million deaths as of December 15, 2022. The development of different epidemiological tools have helped predict new outbreaks and assess the behavior of clinical variables in different health contexts. In this study, we aimed to monitor concentrations of SARS-CoV-2 in wastewater as a tool to predict the progression of clinical variables during Waves 3, 5, and 6 of the pandemic in the Spanish city of Xátiva from September 2020 to March 2022. We estimated SARS-CoV-2 RNA concentrations in 195 wastewater samples using the RT-PCR Diagnostic Panel validated by the Center for Disease Control and Prevention. We also compared the trends of several clinical variables (14-day cumulative incidence, positive cases, hospital cases and stays, critical cases and stays, primary care visits, and deaths) for each study wave against wastewater SARS-CoV-2 RNA concentrations using Pearson's product-moment correlations, a two-sided Mann-Whitney U test, and a cross-correlation analysis. We found strong correlations between SARS-CoV-2 concentrations with 14-day cumulative incidence and positive cases over time. Wastewater RNA concentrations showed strong correlations with these variables one and two weeks in advance. There were significant correlations with hospitalizations and critical care during Wave 3 and Wave 6; cross-correlations were stronger for hospitalization stays one week before during Wave 6. No association between vaccination percentages and wastewater viral concentrations was observed. Our findings support wastewater SARS-CoV-2 concentrations as a potential surveillance tool to anticipate infection and epidemiological data such as 14-day cumulative incidence, hospitalizations, and critical care stays. Public health authorities could use this epidemiological tool on a similar population as an aid for health care decision-making during an epidemic outbreak.

SarQoL Questionnaire in Community-Dwelling Older Adults under EWGSOP2 Sarcopenia Diagnosis Algorithm: A New Screening Method?

This article is an observational and cross-sectional study that related the result obtained in the questionnaire for the evaluation of quality of life related to muscle mass (SarQoL) and the prevalence of sarcopenic pathology measured under the EWGSOP2 algorithm. Participants were 202 community-dwelling older adults living in Valencia, Spain. The prevalence of sarcopenia in men was 28.9%, while in women it was 26.2%. In the case of the SarQoL questionnaire, the mean score obtained for men was 75.5 and 72.6 for women, showing significant differences in both sexes between the results obtained by the group with and without sarcopenia. After the exhaustive data analysis, a high discriminative capacity for sarcopenic disease was found in the SarQoL questionnaire total score and in domains 2 (locomotion), 4 (functionality) and 5 (activities of daily living). In accordance with the existing controversy regarding the use of SARC-F as a screening method for sarcopenia, the authors pointed out the capacity of domain 2 (locomotion) in isolation as a possible screening method for this disease, exposing a high risk of suffering sarcopenia when scores in this domain were below 60 points. Further research is needed to develop new lines of research as these showed in this work, as well as new and easily applicable screening methods for sarcopenia in clinical practice, that allow a rapid detection of this disease in the community.

Knowledge about Pain in Spanish Nursing Students.

BACKGROUND: All nurses should receive training and education regarding pain as part of their pre-graduate stage, as its assessment and appropriate management when treating patients largely depends on them. With the right knowledge it is possible to reduce its high prevalence, as well as the serious consequences it can lead to. AIM: To determine the level of knowledge and attitudes towards pain of final-year nursing students in Spain. METHODS: Descriptive cross-sectional study using a convenience sample of five Spanish universities during the academic year 2020-2021. The Spanish version of the Knowledge and Attitudes Survey Regarding Pain (KASRP) was used. In addition, socio-demographic variables such as age, sex, relationship status, employment status, and the number of dependants were collected. The specific palliative or oncology subjects of each university was also assessed. RESULTS: A total of 224 questionnaires were collected. One of the nursing universities obtained the best score in the KASRP (59.75%) which was significant (p = .001). This university was the only one that offers specific subjects in palliative or oncologic care. A training deficit in aspects related to pain assessment and pharmacologic concepts was detected. We found no relationship between the KASRP and the different sociodemographic variables. CONCLUSIONS: Specific training in palliative care improves the students' knowledge regarding pain, although the results did not reach an acceptable minimum. The universities' training programs for Spanish students need to be adapted in order to achieve better results.

Non-use of information and communication technology as a predictor of frailty in postmenopausal midlife and older women.

BACKGROUND: Frailty is a clinically discernible state in which decreased physiological reserve and function result in a reduced ability to cope with stressors. Information and communication technology (ICT) has been proposed as an aid to help with frailty, yet the use of ICT by older people, particularly women, is an understudied area. AIM: To analyze the association between use of ICT (specifically internet functions and social media) and frailty status in postmenopausal midlife and elderly women. METHODS: A cross-sectional study was designed to investigate whether frailty status is related to ICT use in postmenopausal midlife and older women. Community-dwelling women attending primary health care centers for health checks were invited to participate in the study. Postmenopausal status was the only inclusion criterion, whereas limitations that could interfere with use of ICT were exclusion criteria. The Fried phenotype was used to assess frailty. Four types of ICT use were examined: the internet for e-mail, the internet for other functions, and social media (WhatsApp or Facebook). Chi-square test and multivariate multinomial regression analysis were used to examine the association between frailty status and ICT use. RESULTS: We included 409 women (age = 67.45 ± 7.81 years, mean ± SD), who were frail (n = 135, 33.01%), pre-frail (n = 159, 38.87%), or robust (n  =  115, 28.11%). Frailty status was significantly and inversely associated with any ICT use, showing a strong association with use of WhatsApp (P < 0.001) and internet searches (P < 0.001). ICT non-use was a predictor of frailty, while ICT users were more likely to be robust (OR 10.62; 95% [CI], 5.34-21.10) or pre-frail (OR 9.03; [CI], 95% 5.18-15.74). CONCLUSION: Postmenopausal midlife and older women not using ICT were more likely to be frail.

El rendimiento físico fue evaluado a través del cuestionario iPaq-e, así como el test SPPB y el test de velocidad de la marcha de 4 metros. Resultados: la muestra total comprendió un total de 164 participantes con una edad media de ± 72 años. Un 26,2 % de la muestra presentaban una ingesta de proteínas inferior a la recomendada por la FAO/OMS. El 25,6 % de las mujeres presentaban algún estadio de sarcopenia y, en cuanto a la prevalencia de la obesidad sarcopénica, un 12,2 % de la muestra se encontró afectada por dicha enfermedad. Se encontraron relaciones significativas entre el consumo de proteína y la prevalencia de la sarcopenia (p = 0,021) y la obesidad sarcopénica (p = 0,043). Se encontraron diferencias significativas relacionadas entre la mayoría de macronutrientes y micronutrientes a estudio y el consumo proteico. No se encontró ninguna relación entre la ingesta proteica y el rendimiento físico. (AU)

Objectives: the general aging of the population is related to the increase in the prevalence of sarcopenic disease; especially among older women, this pathology is closely related to nutrition and specifically to protein consumption in older adults. The aim of our study was to evaluate the possible relationship between a low protein intake and a higher prevalence of sarcopenic disease, a worse dietary pattern, and lower physical performance in postmenopausal women living in the community. Material and methods: the study was carried out in a total of 164 independent women over 65 years of age, recruited from a municipal social center in Valencia (Benimaclet). The presence of sarcopenic pathology was evaluated using the latest algorithm published by EWGSOP2, and the intake of nutrients through a three-day dietary record. Physical performance was evaluated through the iPaq-e questionnaire, as well as the SPPB test and the 4-meter gait speed test. Results: the total sample comprised 164 women with a mean age of ± 72 years; 26.2 % of the sample had a protein intake lower than recommended by the FAO/WHO; 25.6 % of the women presented some stage of sarcopenia; regarding the prevalence of sarcopenic obesity, 12.2 % of the sample was affected by this disease. Significant relationships were found between protein consumption and the prevalence of sarcopenia (p = 0.021) and sarcopenic obesity (p = 0.043). Significant related differences were found between the majority of macronutrients and micronutrients under study and protein consumption. No relationship was found between protein intake and physical performance. (AU)

Significant related differences were found between the majority of macronutrients and micronutrients under study and protein consumption. No relationship was found between protein intake and physical performance. Conclusions: protein consumption in most of the women studied (73.8 %) was higher than the daily recommendations established by the FAO/WHO. There was a significant relationship between the prevalence of sarcopenia and sarcopenic obesity, and low protein intake. Higher protein intake was associated with a higher energy intake pattern. No relationship was found between protein intake and physical performance of the participants.

Special Issue "Mental Health Issues and Quality of Life in Older Individuals".

There are numerous biological, psychological, and social factors that have a more or less prominent impact on the mental health of older adults [...].

Salivary Testosterone and Cortisol as Biomarkers for the Diagnosis of Sarcopenia and Sarcopenic Obesity in Community-Dwelling Older Adults.

Nowadays, the appearance of sarcopenia (S) or sarcopenic obesity (SO) is related to aging. According to the criteria of the European Working Group on Sarcopenia in Older People (EWGSOP), the feasibility of using salivary cortisol and testosterone levels was analyzed as diagnostic biomarkers of S or SO. One hundred and ninety non-institutionalized people aged ≥65 years were studied, independent of the activities of daily living (ADLs) (Barthel > 60), and sociodemographic variables were determined together with criteria for the diagnosis of S and SO including grip force, lower body strength, appendicular skeletal muscle mass, physical performance, total body fat percentage, body mass index (BMI), waist circumference, and triceps skinfold, together with the levels of salivary cortisol and testosterone. Our results reflected that women presented a higher prevalence of S and SO (21.2% and 30.2%, respectively). A significant difference was observed between salivary testosterone levels and the age of the participants with differences by sex. Testosterone values in men with S and SO were significantly lower (p = 0.043 and p = 0.048, respectively), which suggests a potential use of the biomarker for diagnostic purposes. No significant differences were shown with cortisol values.

Medication errors and risk areas in a critical care unit.

AIMS: The aim of this study was to identify the main medication errors, their causality and the highest risk areas in critical care. DESIGN: A descriptive, longitudinal and retrospective study. METHODS: We performed a systematic analysis of the prescription, transcription and administration records of 2,634 dose units of medications that were administered to a total of 87 critically ill patients during 2018. RESULTS: Final results have shown important medication errors and a high number of significant drug interactions; prescription phase had the highest mistake rate (71%) and cause of errors (68%); transcription stage had a more variable error typology. A significant correlation was observed between the presence of causes and contributing factors to error during the prescription and the commission of errors during the nurse transcription, being the main risk areas the time of antibiotic administration, dilution errors, concentration and speed of administration of high-risk medications and the technique used for nasogastric tube drug administration. CONCLUSION: In critical care, an intolerable number of medication errors are still committed, placing the origin of many of them in the causality and contributing factors identified in the prescription stage. IMPACT: The origin of many of the medication errors and most interactions is in the prescription stage, being the nurse transcription (nurse intervention) in an important filter that prevents a considerable number of errors from finally reaching the patient. The schedule of administration of time-dependent antibiotics, high-risk medications and the technique of administering medications through a nasogastric tube are important risk areas for the commission of medication errors.

Determinants of Knowledge of Pain among Nurses in a Tertiary Hospital in Spain.

BACKGROUND: Poorly controlled pain in patients is related to several complications, such as increased nosocomial infections and mortality, where nurses play a crucial role. AIMS: To analyze determinants of pain as well as nurses' knowledge and attitudes towards pain in the inpatient services of a tertiary center in the Spanish public health network. METHODS: The Knowledge and Attitudes Survey Regarding Pain questionnaire was administered to all nurses in the center from January to March 2019. Additional sociodemographic variables, such as gender, age, employment status, work experience, professional group, and academic degree, were collected and analyzed. Item Response Theory was used for discriminant analysis of each question and its relationship with the final score. RESULTS: A total of 282 questionnaires were collected from those distributed among nurses working in medical, surgical, oncological, and intensive care services. The average score obtained on pain-related knowledge and attitudes was 58.89%. We found significant differences (p < .001) between the KASRP score and the professional group score. There were no differences in final score based on academic level or age. Questions related to pharmacology resulted in low scores and did not discriminate between levels of knowledge, being considered difficult. We did not find items that allowed discriminating between levels of knowledge. CONCLUSIONS: A knowledge gap exists regarding nurses' pharmacological and assessment concepts, and there are differences in knowledge depending on professional group. The KASRP allows for a good discrimination of low levels of knowledge.

Prevalence of Sarcopenia in Community-Dwelling Older Adults in Valencia, Spain.

This study is an observational and cross-sectional study on the prevalence of sarcopenic disease in 202 autonomous older adults; 18.8 and 81.2% were men and women, respectively, living in their own homes in Valencia, Spain. Sarcopenia was diagnosed using the criteria and cutting points for the European Working Group on Sarcopenia in Older People 2 (EWGSOP2), using the tests: SARC-F, grip strength, sit-to-stand, gait speed, appendicular skeletal muscle mass and short physical performance battery. According to the EWGSOP2 criteria, probable sarcopenia was present in 21.1% and 18.3% of men and women, respectively, and the sum of confirmed and severe sarcopenia was 7.9% and 7.3% in men and in women, respectively. A relationship was shown between the prevalence of the disease and the age of the participants, but no significant differences were found between the sum of confirmed and severe sarcopenia between the sexes, nor a relationship between the amount of muscle mass and the strength of grip. The SARC-F questionnaire diagnosed 40% of the sarcopenia cases present in the study. More thorough research is needed to continue using the EWGSOP2 criteria in different populations to establish a correct prevalence of sarcopenic disease in different populations of the world.

Nursing Workload, Knowledge about Pain, and Their Relation to Pain Records.

PURPOSE: To study the relationship between frequency of pain assessment and nursing workload, and also to analyze the frequency of pain assessment and its relation to knowledge and attitudes toward pain on nursing professionals in intensive care unit. METHODS: An ambispective study was conducted in a Spanish tertiary-level intensive care unit between October 2017 and April 2018. For measurement of workload, the Nursing Activities Score scale was used, and for measurement of pain knowledge, the Knowledge and Attitudes Survey Regarding Pain was used. RESULTS: There were 1,207 measurements among 41 nurses and 1,838 among 317 patients. The average nursing workload was high (70.97 points). We found statistically significant positive association between nursing workload and the frequency of assessment (p < .001), as well as frequency of assessment and patients with communicative capacity (p = .008). CONCLUSIONS: Nursing workload affects the registration and assessment of patients' pain, resulting in a greater number of records as the workload performed by nurses increases. It is necessary to study in greater depth how the severity of pain, gender of the patients, and workload of nurses influence pain registration and assessment.

Effects of Leucine Administration in Sarcopenia: A Randomized and Placebo-controlled Clinical Trial.

Treating sarcopenia in older individuals remains a challenge, and nutritional interventions present promising approaches in individuals that perform limited physical exercise. We assessed the efficacy of leucine administration to evaluate whether the regular intake of this essential amino acid can improve muscle mass, muscle strength and functional performance and respiratory muscle function in institutionalized older individuals. The study was a placebo-controlled, randomized, double-blind design in fifty participants aged 65 and over (ClinicalTrials.gov identifier NCT03831399). The participants were randomized to a parallel group intervention of 13 weeks' duration with a daily intake of leucine (6 g/day) or placebo (lactose, 6 g/day). The primary outcome was to study the effect on sarcopenia and respiratory muscle function. The secondary outcomes were changes in the geriatric evaluation scales, such as cognitive function, functional impairment and nutritional assessments. We also evaluated whether leucine administration alters blood analytical parameters and inflammatory markers. Administration of leucine was well-tolerated and significantly improves some criteria of sarcopenia in elderly individuals such as functional performance measured by walking time (p = 0.011), and improved lean mass index. For respiratory muscle function, the leucine-treated group improved significantly (p = 0.026) in maximum static expiratory force compared to the placebo. No significant effects on functional impairment, cognitive function or nutritional assessment, inflammatory cytokines IL-6, TNF-alpha were observed after leucine administration compared to the placebo. The use of l-leucine supplementation can have some beneficial effects on sarcopenia and could be considered for the treatment of sarcopenia in older individuals.

Medication errors and drug knowledge gaps among critical-care nurses: a mixed multi-method study.

BACKGROUND: Medication errors are a serious and complex problem in clinical practice, especially in intensive care units whose patients can suffer potentially very serious consequences because of the critical nature of their diseases and the pharmacotherapy programs implemented in these patients. The origins of these errors discussed in the literature are wide-ranging, although far-reaching variables are of particular special interest to those involved in training nurses. The main objective of this research was to study if the level of knowledge that critical-care nurses have about the use and administration of medications is related to the most common medication errors. METHODS: This was a mixed (multi-method) study with three phases that combined quantitative and qualitative techniques. In phase 1 patient medical records were reviewed; phase 2 consisted of an interview with a focus group; and an ad hoc questionnaire was carried out in phase 3. RESULTS: The global medication error index was 1.93%. The main risk areas were errors in the interval of administration of antibiotics (8.15% error rate); high-risk medication dilution, concentration, and infusion-rate errors (2.94% error rate); and errors in the administration of medications via nasogastric tubes (11.16% error rate). CONCLUSIONS: Nurses have a low level of knowledge of the drugs they use the most and with which a greater number of medication errors are committed in the ICU.

OBJECTIVE: To evaluate the role of peripheral inflammation (leukocyte differential count, the proinflammatory cytokines IL-beta, TNF-α, IL-6, IL-8, and the inflammatory markers fibrinogen and C-reactive protein [CRP]) in frailty syndrome in patients with prostate cancer (CaP) undergoing antiandrogen therapy (ADT). METHODS: A total of 46 men between 51 and 92 years of age with CaP and receiving ADT were classified as frail, prefrail or robust according to the Fried scale. A geriatric assessment was performed, based on the Minimental State Examination for cognitive function, the Barthel index for basic activities of daily living, the Yesavage scale for geriatric depression, and the Athens insomnia scale. In addition, blood samples were collected to assess peripheral inflammation biomarkers including proinflammatory cytokines, fibrinogen, CRP and leukocyte differential count, as well as other biochemical and hematological parameters. RESULTS: A significant negative correlation between the severity of frailty syndrome and lymphocyte count was observed (P < 0.01). The concentration of IL-6 (P < 0.05), CRP (P < 0.05), and fibrinogen (P < 0.01) were significantly associated with frailty syndrome, but not of TNF-α, IL-beta, or IL-8. The severity of frailty syndrome was not dependent upon the clinical disease stage at diagnosis, the time elapsed since CaP diagnosis, the presence of metastases, or prostatectomy. CONCLUSIONS: Further research into the role of leukocyte subtypes and peripheral inflammation and the associated adverse outcomes in patients with CaP under ADT is warranted in order to tailor interventions aimed at reducing symptoms of frailty syndrome, such as loss of muscle strength and low physical activity.
