Serum biomarkers related to frailty predict negative outcomes in older adults with hip fracture.

PURPOSE: Hip fracture is a public health problem worldwide. Traditional prognostic models do not include blood biomarkers, such as those obtained by proteomics. This study aimed to investigate the relationships between serum inflammatory biomarkers and frailty in older adults with hip fracture as well as adverse outcomes at one and three months after discharge. METHODS: A total of 45 patients aged 75 or older who were admitted for hip fracture were recruited. At admission, a Comprehensive Geriatric Assessment (CGA) was conducted, which included a frailty assessment using the Clinical Frailty Scale (CFS). Blood samples were collected before surgery. Participants were followed up at one and three months after discharge. The levels of 45 cytokines were analyzed using a high-throughput proteomic approach. Binary logistic regression was used to determine independent associations with outcomes, such as functional recovery, polypharmacy, hospital readmission, and mortality. RESULTS: The results showed that IL-7 (OR 0.66 95% CI 0.46-0.94, p = 0.022) and CXCL-12 (OR 0.97 95% CI 0.95-0.99, p = 0.011) were associated with better functional recovery at three months after discharge, while CXCL-8 (OR 1.07 95% CI 1.01-1.14, p = 0.019) was associated with an increased risk of readmission. CONCLUSIONS: These findings suggest that immunology biomarkers may represent useful predictors of clinical outcomes in hip fracture patients.

Sex and age differences in the achievement of control targets in patients with type 2 diabetes: results from a population-based study in a South European region.

BACKGROUND: We aimed to determine the degree to which control targets of glycaemia and cardiovascular risk factors were achieved among patients with type 2 diabetes and to investigate sex- and age-related differences in this population. METHODS: This cross-sectional, population-based study was conducted in Spain. Glycated hemoglobin (HbA1c), blood pressure, LDL-c, HDL-c, triglycerides, BMI, and smoking history were obtained from electronic clinical primary care records (n = 32,638 cases). The proportions of patients who met control targets were determined according to sex and age groups. Comparisons between groups were conducted with t-tests for continuous variables, tests for trends in proportions for categorical and ordinal variables, and Pearson's chi-square tests and binary logistic regression models for categorical variables. RESULTS: The overall proportions of patients with type 2 diabetes who met the target objectives for HbA1c (<7 %, 53 mmol/mol), blood pressure (130/80 mmHg), and LDL-cholesterol (100 mg/dl) were 60, 40 and 41 %, respectively. Women were less likely than men to meet the control targets of HbA1c (59 vs 61 %), LDL (35 vs 45 %), and HDL (58 vs 78 %). Patients under 65 years of age presented poorer control than older age groups. Only a minority of patients with type 2 diabetes met the composite target objectives for glycemic control, blood pressure, and LDL. CONCLUSIONS: There are differential gaps in the control results of female patients and younger patients, which should prompt improvements in case management and care. There is room for further improvement in the cardiometabolic control of patients with type 2 diabetes.

The impact of loneliness and social isolation on the benefits of an exercise program with hospitalised older adults.

OBJECTIVES: This study aimed to assess the prevalence and impact of loneliness (De Jong Gierveld scale) and isolation (Lubben scale) on the effects of a hospital-based exercise programme. DESIGN: Secondary analysis of a randomised clinical trial. SETTING: Acute Geriatric Unit of a tertiary hospital in Spain. PARTICIPANTS: 103 hospitalised older adults. INTERVENTION: Individualised multicomponent exercise program (20-minute sessions twice a day for 3 consecutive days). RESULTS: Among the 103 randomised patients included in the analysis (both arms included), 58.3% were male, and their mean age was 87.3 (4.5) years. According to the Lubben scale, 15.8% of patients were at risk of isolation, while 62.7% were in a situation of severe or moderate loneliness according to the De Jong Gierveld scale. In the non-isolated group, training showed a substantial positive impact on Geriatric Depression Scale (B = -1.25, 95% CI = -0.24 to -0.27). In the isolated group, all outcomes improved, but only the Quality of Life showed significant changes (B = 35, 95% CI = 4.96-35.8). The SPPB test (B = 1.62, 95% CI = 0.19-3.04) and Quality of Life, (B = 17.1, 95% CI = 1.84-32.3) showed a significant improvement in the non-loneliness exercise group while no differences were found in the loneliness group. CONCLUSION: Despite the high prevalence of loneliness and social isolation, individualised exercise programs provide significant benefits to hospitalised patients, especially in quality of life.

Could a Tailored Exercise Intervention for Hospitalised Older Adults Have a Role in the Resolution of Delirium? Secondary Analysis of a Randomised Clinical Trial.

Delirium is a transient neurocognitive disorder. Nonpharmacological measures can be efficient in reducing the incidence and intensity of delirium, but there is a paucity of evidence when using a physical exercise program exclusively. This was a secondary analysis of a randomised clinical trial that provided evidence on the functional and cognitive benefits of an individualised exercise intervention in hospitalised older adults. Of the 370 patients who participated in the trial, 17.1% in the intervention group had delirium and 12.1% in the control group. After the exercise intervention, 84.6% of the patients in the intervention group showed improvement in delirium compared to 68.4% of patients in the control group. Despite the fluctuating nature of delirium,we show that it is feasible to establish individualised exercise interventions in hospitalised geriatric patients in the periods when patients are able to cooperate. Baseline functional status, measured by the Barthel Index, is a clinical marker that could help to identify those who will benefit most.

Tailored Prevention of Functional Decline through a Multicomponent Exercise Program in Hospitalized Oncogeriatric Patients: Study Protocol for a Randomized Clinical Trial.

BACKGROUND: Cancer mostly affects older adults, causing a wide variety of diagnostic and therapeutic dilemmas. One of the most important moments in cancer patients is the hospitalization period, in which older patients usually remain bedridden for many hours and this may lead to the appearance of sarcopenia and disability. METHODS: We present the research protocol for a randomized controlled trial that will analyze whether an intervention applied to older patients (≥ 65 years) who are hospitalized for acute medical conditions in an Oncology Department improves function. A total of 240 hospitalized older patients will be recruited in the Hospital Universitario de Navarra, Pamplona, Spain, and they will be randomized. The intervention consists of a multicomponent exercise training program that will take place for 4 consecutive days (2 sessions/day). The control group will receive usual hospital care, which will include physical rehabilitation when needed. The primary end point will be the change in functional capacity from baseline to hospital discharge, assessed with the Short Physical Performance Battery (SPPB). Secondary end points will be changes in cognitive and mood status, quality of life, fatigue, strength (dynamic and handgrip), pain, nutrition, length of stay, falls, readmission rate and mortality at 3 months after discharge. RESULTS: Basal data of the patients included in the RCT are described. The foreseen recruitment will not be achieved due to the context of the Covid pandemic and the significantly different responses observed during the clinical trial in oncogeriatric patients compared to our previous experience in older adults hospitalized for medical reasons. DISCUSSION: If our hypothesis is correct and shows that a multicomponent, individualized and progressive exercise program is an effective therapy for improving the capacity of acutely hospitalized older patients compared to usual care, a change in the current system of hospitalization may be justified in oncogeriatric patients.

Preoperative hemogram as a predictive factor for iron deficit and/or transfusion in patients scheduled for arthroplasty.

INTRODUCTION: anemia and iron deficiency predispose to an increased risk of transfusion with a consequent increase in morbidity and mortality. The study analyzes whether blood cell count parameters in addition to detecting anemia can predict iron deficiency and/or transfusional risk in patients undergoing mostly to scheduled primary hip and knee arthroplasty. OBJECTIVE: To analyze how blood cell count parameters predict iron deficiency and/or transfusional risk in patients undergoing programmed arthroplasty. MATERIAL AND METHODS: The analytical and transfusion results of 522 patients undergoing arthroplasty have been prospectively collected between 2013 and 2019 and the discriminative and predictive capacity of the basic parameters of the red cells have been analyzed; hemoglobin (Hb), mean cell volume, mean cell hemoglobin (HCM) and red blood cell distribution width (RDW) for the identification of presurgical iron deficiency and postsurgical transfusion. RESULTS: Anaemia was detected in 6.6%, "suboptim" Hb (<13 g/dL) in 14.5% and iron deficiency in 32.4%. Anemia detects only 13.8% of ID. After logistic regression analysis, the multivariate model significantly related Hb (p = .004), mean corpuscular hemoglobin (MCH) (p = .026), and the red cell distribution width (RDW) (p = .001) with ID; but mean corpuscular volume (MCV) is not significant. Hb, age and transferrin saturation index have been the only risk factors for transfusional risk of the parameters analyzed. CONCLUSIONS: The hemogram contains parameters that correlate with iron deficiency, however, mean cell volume, so widely used for the orientation of iron deficiency, is not valid as a discriminator of iron deficiency in this group of patients. Low Hb and transferrin saturation index are modifiable predictors for transfusion risk.

Missing patients in "Major Trauma Registry" of Navarre: incidence and pattern.

BACKGROUND: Trauma registries (TR) collect information about trauma patients according to inclusion criteria, and it helps to establish protocols to improve care. However, all TR deal with incompleteness. The aim of this study is to assess the number of patients not included despite fulfilling inclusion criteria in our regional TR and identifying the predictors for being missing. METHODS: The sample was randomly selected. Two months of each year from 2010 to 2014 (5 years) were selected, and medical files of all patients attended in the emergency department room during those months were studied. Patients who were already correctly included in the TR were assigned to the 'included' group, and patients who should have been but were not to the 'missing' group. The multivariable logistic regression analysis was performed to identify predictors for being missed from the TR. RESULTS: Of a total of 200, 79 (40 % approximately) were identified as missing. We defined the characteristic profiles of missing patients and found that the hospital RTS and the number of injuries are independent predictors to be missing in our trauma registry, with an adjusted odds ratio of 1844 [95 % (1092-3114) and 0.574 (95 % CI 0.428-0.770)], respectively. CONCLUSIONS: Overall, 40 % of the patients who met the inclusion criteria of the TR were not included in the registry. Our results can be generalized to other trauma records based on Utstein style, because we think probably that this fact is also happening in other databases.
