Estado nutricional del paciente en hemodiálisis y factores asociados / Nutritional status of the patient on hemodialysis and associated factors

Introducción: La desnutrición en pacientes crónicos en diálisis tiene una alta prevalencia e importante repercusión en la morbimortalidad. Dado que no existen estudios previos en nuestro servicio, planteamos un estudio cuyo objetivo es evaluar el estado nutricional y los factores asociados. Material y Método: Estudio descriptivo, observacional, transversal, el segundo trimestre de 2015, en los pacientes en programa de hemodiálisis de un hospital comarcal. Se registró la edad, sexo, I. de Charlson, técnica de diálisis, IMC, tiempo en diálisis, albúmina, PCR, colesterol y transferrina séricas. Se utilizó como instrumento la Valoración global subjetiva y el Score Malnutrición Inflamación. Resultados: Se analizaron 35 pacientes, la edad media fue 72,2 años (DS: 11,8), 34,3% fueron mujeres, el IMC es 27,1 (DS: 4,9), I. de Charlson 6,4 (DS: 1,7), 77,1% hacían diálisis convencional y 22,9% hemodiafiltración en línea. Según el test MIS el 46% tenía buen estado nutricional y 54% estaba mal nutrido. Según la VGS 66% tenía buen estado nutricional, 31% riesgo de desnutrición y 3% desnutrición severa. La VGS se relaciona con el IMC (p: 0,02), creatinina (p: 0,001), colesterol total (p: 0,02) y PCR (p: 0,01); no con la edad, tiempo en hemodiálisis, I. Charlson, transferrina y albúmina(p> 0,05). El Score Malnutrición Inflamación (MIS) se relaciona con el IMC (p: 0,002), I. Charlson (p: 0,01), creatinina (p: 0,009) y PCR (p: 0,02); no con la edad, tiempo en hemodiálisis, colesterol total, transferrina y albúmina (p> 0,05). Conclusión: Existe buena correlación entre las dos herramientas y los parámetros analíticos utilizados. Los pacientes en hemodiafiltración en línea tienen buen estado nutricional. No existe un único parámetro que valore la nutrición. Se sugiere que es necesaria la valoración nutricional dada la alta prevalencia que existe (AU)

Introduction: Malnutrition in chronic dialysis patients has a high prevalence and important repercussion in morbidity and mortality. Since there are no previous studies in our service, we propose a study whose objective is to evaluate the nutritional status and associated factors. Material and Method: A descriptive, observational, cross-sectional study, in the second trimester of 2015, in patients in the hemodialysis program of a county hospital. Age, sex, Charlson’s index, dialysis technique, BMI, time on dialysis, albumin, CRP, cholesterol and serum transferrin were recorded. Subjective global assessment and Score Malnutrition Inflammation were used as instrument. Results: We analyzed 35 patients, mean age was 72.2 years (SD: 11.8), 34.3% were women, BMI was 27.1 (SD: 4.9), Charlson index 6.4 (DS: 1.7), 77.1% were on conventional dialysis and 22.9% were on-line hemodiafiltration. Regarding the MIS test, 46% had good nutritional status and 54% were malnourished. According to the VGS, 66% had good nutritional status, 31% risk of malnutrition and 3% severe malnutrition. VGS was related to BMI (p: 0.02), creatinine (p: 0.001), total cholesterol (p: 0.02), and CRP (p: 0.01); and it was not related to age, time on hemodialysis, Charlson’s index, transferrin and albumin (p> 0.05). The Score Malnutrition Inflammation (MIS) was related to BMI (p: 0.002), Charlson’s index (p: 0.01), creatinine (p: 0.009) and CRP (p: 0.02); not with age, time on hemodialysis, total cholesterol, transferrin and albumin (p> 0.05). Conclusions: There is good correlation between the two tools and analytical parameters used. Patients in on-line hemodiafiltration have good nutritional status. There is no single parameter that evaluate nutrition. The inclusion of nutritional assessment is suggested given the high prevalence (AU)

Red eye emergencies in primary care.

Severe red eye conditions can be the result of intraocular inflammation, corneal insults or inflammation, and acute glaucoma. These pathologies require the knowledge and assessment tools of an ophthalmologist. This article will discuss red eye emergencies that the NP should promptly recognize and refer to ophthalmology.

An exploratory study of the patients' sleep patterns and inflammatory response following cardiopulmonary bypass (CPB).

AIMS AND OBJECTIVES: To describe sleep patterns and inflammatory response postCPB, determine sleep pattern changes and inflammatory response over time and explore relationships between sleep and biomarkers of stress and inflammation. BACKGROUND: Despite the numerous citations of the role of sleep in restoration and health maintenance, a paucity of research exists about this phenomenon in patients undergoing CPB. Specifically, there is no research that has explored correlations between sleep patterns and systemic inflammatory response in adult cardiac surgery patients. DESIGN: Exploratory, repeated-measures, correlational study. METHOD: Subjects were recruited from a Midwestern urban hospital. Of the 25 eligible subjects, 16 males and four females completed the study. Wrist actigraphy was used to measure sleep variables. Salivary cortisol and C-reactive protein (C-RP) levels were measured daily. Data were collected during postoperative nights/days 1 through 4 (T1-T4). RESULTS: Subjects' sleep onset latency (SOL) median scores (0 minute) were within normal range across time periods, whereas median scores for wake after sleep onset (WASO > 270 minutes), sleep fragmentation index (SFI >51%), total sleep time (<153 minutes) and sleep efficiency index (SEI <36%) fell outside the normal ranges. Changes in the median sleep scores over time, however, were not significant at p > 0·05. Median cortisol levels were within normal range (0·3-0·8 µg/dl) from T1-T4, but the C-RP level peaked at T2 (median = 2370 pg/ml). Strong correlations were found: (1) between SFI-cortisol (rs = 0·82), C-RP (rs = 0·65) - WBC (rs = 0·69); (2) between SEI-C-RP (rs = 0·58); (3) between WASO-WBC (rs = 0·48), WASO and cross-clamp time (rs = 0·50); and (4) between SOL-age (rs = -0·55) at p < 0·05. CONCLUSIONS: Subjects were severely sleep-deprived with inflammatory response exaggerations warranting further investigations using larger sample sizes. RELEVANCE TO CLINICAL PRACTICE: This study offers a foundation for developing a conceptual model explaining mechanisms of sleep disturbance and inflammatory response postCPB. This knowledge is crucial for testing sleep-promoting interventions to modulate inflammatory responses essential for preventing complications, and restoring health.

Exhaustion, immuno-inflammation, and pathogen burden after cardiac surgery: an exploratory study.

BACKGROUND: Exhaustion, a consequence of prolonged stress characterized by unusual fatigue, is associated with increased risk of cardiac morbidity and mortality. In patients recovering from coronary artery bypass (CABG), little is known about the relationship of 1) immune-mediated inflammation and resultant endothelial activation, and 2) cumulative exposure to infectious pathogens (pathogen burden (PB)) implicated in coronary atherosclerosis to exhaustion. AIM: The aim of this exploratory study was to investigate the association of PB, inflammatory markers (interleukin (IL)-6, IL-10) and a marker of endothelial activation (soluble intercellular adhesion molecule-1 (sICAM-1)) to exhaustion. METHODS: One to two months post-CABG, 42 individuals who met inclusion criteria were assessed for exhaustion using the Maastricht Interview for Vital Exhaustion. Serum IgG antibodies to herpes simplex virus (HSV)-1, HSV-2, cytomegalovirus, Epstein Barr virus, and inflammatory and endothelial activation markers were measured by enzyme-linked immunosorbent assay. Pathogen burden was defined as the total number of seropositive exposures: low (0-1), moderate (2-3), and high (4). RESULTS: Prevalence of exhaustion was 40.5%. Relative to non-exhausted patients, exhausted patients demonstrated a higher frequency of moderate PB (h=0.73, p=0.04) but lower frequency of high PB (h=1.05, p=0.03). Exhaustion showed a non-significant trend for positive correlations with IL-6 and sICAM-1 levels, and inverse relation to PB. In subgroup analysis, exhausted patients had stronger correlations with IL-6 and IL-6:IL-10 and a tendency towards higher serum IL-10 concentrations compared with their non-exhausted counterparts. CONCLUSION: This hypothesis-generating study provides preliminary evidence that elevated post-CABG exhaustion may be associated with PB, inflammation, and endothelial activation.

Iron deficiency anaemia in chronic kidney disease.

BACKGROUND: Iron Deficiency Anaemia (IDA) has been shown to be the most common cause of anaemia worldwide. It is accepted that people with chronic kidney disease (CKD) develop anaemia as their kidney function declines. METHODS: To better understand IDA in CKD, it is necessary to appreciate the normal iron metabolism and utilisation of iron and how these processes can be disordered in patients with CKD. The problems related to infection / inflammation and oxidative stress are examined. Whilst National and international guidelines recommend specific tests for IDA, these and alternative tests are reviewed. CONCLUSIONS: Whilst iron supplementation is necessary for CKD patients with IDA, iron metabolism and utilisation can be affected by factors such as infection or inflammation. Iron is essential element for all life, it can be toxic to cells through the process of oxidative stress. The recommended tests for IDA may be affected by factors such as infection and inflammation. Alternative tests are available, which may be a more accurate indicator of IDA as they are not affected by external factors.

Inflammatory cytokine levels and breast cancer risk factors: racial differences of healthy Caucasian and African American women.

PURPOSE/OBJECTIVES: To examine racial differences in inflammatory cytokine levels (interleukin [IL]-6 and interferon-gamma [IFN-γ]) and breast cancer (BC) risk factors between healthy Caucasian and African American women; to examine differences in relationships of inflammatory cytokine levels with BC risk factors between these groups of women; and to determine the independent contribution of race to IL-6 and IFN-γ after controlling for relevant covariates. DESIGN: Cross-sectional and correlational descriptive design. SETTING: Community surrounding a state university health system in the southeastern United States. SAMPLE: 113 healthy women (65 Caucasians and 48 African Americans) aged 20 years or older and not pregnant. METHODS: Secondary analysis of data collected from self-report questionnaires and blood samples. MAIN RESEARCH VARIABLES: Inflammatory cytokine levels, BC risk factors (age, age at menarche, age at first live birth, family history of BC, breast biopsy, breastfeeding history and duration, body mass index, and physical activity), and race. FINDINGS: Significant racial differences were noted in IL-6 and IFN-γ levels, reproductive or hormonal and lifestyle BC risk factors, and relationships between African American and Caucasian women. Controlling for all other effects, race appeared to be a significant predictor for IL-6 and IFN-γ. CONCLUSIONS: Racial differences in inflammatory cytokines and BC risk factors may provide partial evidence for existing racial disparities in BC for African American and Caucasian women. Additional studies are needed to confirm that potential. IMPLICATIONS FOR NURSING: Additional biobehavioral research in racial disparities in BC may help to inform nurses to target race-specific modifications of lifestyle and behavioral factors to reduce BC health disparity between African American and Caucasian women. KNOWLEDGE TRANSLATION: Being an African American woman predicted a higher level of inflammatory cytokine production after controlling for selected BC risk factors. Great potential exists for inflammatory responses as one of the underlying biologic mechanisms for existing BC disparity and for culturally tailored lifestyle or behavioral modification interventions for reducing BC risk and racial disparity.

Inflammation and traumatic stress: the society to cells resiliency model to support integrative interventions.

BACKGROUND: Posttraumatic stress disorder (PTSD) is a prevalent psychiatric disorder that develops following a traumatic event and has substantial health implications, including high rates of health morbidity and mortality, as well as significant health-related costs. Medical risks that are associated with PTSD often have an underlying inflammatory pathology, suggesting that inflammation contributes to these health declines. OBJECTIVES AND DESIGN: In this critical literature review, the authors examine the medical risks associated with PTSD and the inflammatory mechanisms that likely underlie these risks. RESULTS AND CONCLUSIONS: The authors offer a review of their "Cells to Society Resiliency Model" to motivate the development of integrative interventions that include factors of society, community, family, individual, physiological, and cellular factors to thereby reduce the health risks associated with PTSD.

Evaluation of the anti-inflammatory effects of ellagic acid.

Few studies have investigated the anti-inflammatory properties of ellagic acid and no published studies have examined the effects of ellagic acid in combination with anesthetic adjuvants. In this study, 54 Sprague-Dawley rats were assigned to one of six groups: (1) vehicle; (2) ketorolac and vehicle; (3) meloxicam and vehicle; (4) ellagic acid and vehicle; (5) ellagic acid, ketorolac, and vehicle; and (6) ellagic acid, meloxicam, and vehicle. Groups 5 and 6 investigated interactions between ellagic acid and cyclooxygenase inhibitors. Paw inflammation was induced with 3% carrageenan and was measured with a plethysmometer at 30 minutes and 4, 8, and 24 hours after intraperitoneal injection. All rats received one intraperitoneal injection of equivalent volumes according to group assignment. Analysis of covariance followed by post hoc analysis determined that ketorolac was the only compound to significantly reduce paw edema at 4 hours (P = .019); ellagic acid alone (P = .038) and the combination of ellagic acid and ketorolac (P = .038) were the only compounds to significantly reduce paw edema at 8 hours. At 24 hours, only ellagic acid was effective (P = .01). Our findings suggest that ellagic acid may be effective against inflammation, may have a prolonged onset and duration of action, and may interact with known cyclooxygenase inhibitors.

The principles of inflammation in the development of rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory condition that involves all elements of the immune response. The aetiology of RA is complex and centres on the development of autoantibodies and immune complexes. The pathogenesis is multistage and involves cytokines, angiogenesis and rheumatoid factor. Nurses managing patients who suffer with RA need to be aware of the pathological changes involved in the disease and its contribution to the progression of the condition. The diagnosis of RA involves blood screening for rheumatoid factor, raised erythrocyte sedimentation rate (ESR), use of arthroscopy to provide evidence of histological changes in the synovium, presenting symptoms, and changes on X-ray. Patient assessment will consider both patient-specific and disease-specific variables, including evidence of non-articular manifestations of RA. Long-term care revolves around trying to maintain patient mobility and the protection of unaffected joints, monitoring for the side-effects from medication and progression of the disease or development of non-articular manifestations.

New perspectives and emerging therapies for immune-mediated inflammatory disorders.

Chronic inflammatory diseases, such as rheumatoid arthritis, psoriasis, and Crohn's disease, affect a large segment of the population in the United States. Recent research suggests that, in many inflammatory conditions, an inflammatory protein or cytokine, specifically tumor necrosis factor-alpha (TNF-alpha), appears to play an important role. Medications designed to treat these chronic inflammatory diseases, in addition to alleviating its symptoms, have become important therapeutic alternatives. This article will discuss specific Immune Mediated Inflammatory Disorders (I.M.I.D.), their treatment and management, as well as the current clinical application and potential future role of TNF-alpha antagonists as a common therapeutic modality.

Infection and inflammation in dialysis patients: impact on laboratory parameters and anemia. Case study of the anemic patient.

Infection and inflammation trigger an acute-phase response that can precipitate the development of mild to moderate anemia. In many cases, changes in hematological parameters may be the initial sign of an occult infectious or inflammatory disorder. In dialysis patients, the decrease in erythropoiesis attributed to these conditions is often additive--aggravating the preexisting anemia associated with end-stage renal disease (ESRD). Nephrology nurses are in a unique position to conduct regular physical assessments and laboratory evaluations to proactively detect infection or inflammation and limit the short- and long-term impact of these conditions.

Understanding cytokines. Part II: Implications for nursing research and practice.

Cytokines are small signaling proteins released from a variety of cells that influence virtually every aspect of growth and development and every host response to infection, injury, and inflammation. Because of their widespread and potent effects across the life span, cytokines without a doubt influence nursing research and practice. From physiological and adaptive effects of cytokines to cytokine-induced diseases, nurses and nursing care are involved. Part II of this review highlights a few of the many examples of cytokines functioning in response to infection and inflammation, during the processes of reproduction, and in a variety of pathophysiological states. Implications for nursing research and practice are emphasized.

Making sense of ... clinical features of inflammation.

Although often associated with abnormal pathological processes, inflammation is a normal physiological response. This paper defines inflammation, looks briefly at the physiological processes involved and discusses implications for nursing.
