Abstract
OBJECTIVE To analyze the concordance between a hemoglobinometer with capillary blood sample and the clinical laboratory with a venous blood sample. DESIGN Cross-sectional concordance study. LOCATION Care Centre Primary Bufalà-Canyet Primary and Care Centre Primary Dalt la Vila Primary Care Center, Badalona, Barcelona. PARTICIPANTS Random selection of participants who attended routine blood tests. Over 18years old. No abandonment or loss was obtained. MAIN INTERVENTIONS AND MEASUREMENTS Sex, age, and reason for the blood test were collected from the medical history. Venous blood is drawn, and simultaneously, capillary blood is collected. RESULTS 120 individuals are included, with an average age of 58.9years. The Bland-Almant graph showed differences within the confidence intervals for hemoglobin and hematocrit. The mean differences between the values of the Verio Q Red hemoglobinometer and those of the clinical laboratory were -0.42mg/dl for hemoglobin and -1.25% for hematocrit. The intraclass correlation coefficient showed excellent correlation for hemoglobin and hematocrit between the Verio Q Red hemoglobinometer and the clinical laboratory. Pearson's correlation for hemoglobin was 0.737 and for hematocrit 0.787. CONCLUSIONS The Verio Q hemoglobinometer is a valid tool for the early diagnosis of anemias and can be very useful in primary care consultations.

Zhang H, Wei X, Chen X, Sun X. Mortality from all-cause and cause-specific in the elderly: Joint implications of anemia and frailty. Arch Gerontol Geriatr 2023; 115:105213. [PMID: 37783022 DOI: 10.1016/j.archger.2023.105213] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 08/30/2023] [Accepted: 09/23/2023] [Indexed: 10/04/2023]
Abstract
BACKGROUND Anemia is prevalent among older adults, and it contributes to the incidence of frailty. In turn, the frail elderly may be deficient in nutrients, including iron, vitamin B-12, and folate, that can be materials for human blood, as a result of their limited nutrient intake, resulting in anemia. Both anemia and frailty are associated with an increased risk of mortality in elderly adults. However, the combined influence of anemia and frailty on mortality is unclear. METHODS Data obtained from NHANES 2007-2014 were analyzed in this study. Frailty status was determined using a modified Fried Phenotype, and anemia was defined according to the criteria set by the World Health Organization. Public-use Linked Mortality files until December 31, 2019 were available. The weighted Cox proportional hazard regression models were used to estimate separate effects and joint effects of frailty and anemia on all-cause and cause-specific mortality. RESULTS This study analyzed 6,406 participants aged 60 years or older. Over a 13-year follow-up period, considering participants with no anemia and no frailty as reference, participants with both anemia and frailty had nearly fourfold the all-cause (HR (95% CI): 4.03 (2.95,5.52)), more than four-time the cardiovascular (HR (95% CI): 4.24(2.46,7.32)) mortality risk, and above five-time the non-CVD/non-cancer (HR (95% CI): 5.17 (3.58,7.46)) mortality risk. CONCLUSIONS The study indicated that older adults who exhibit low levels of hemoglobin and frailty are at the greatest risk for all-cause, cardiovascular, cancer, and non-cancer/non-cardiovascular mortality, with the exception of cancer mortality, which was only increased by anemia.

Abstract
Background. Cognitive impairment (CI) is one of the important disability factors in the elderly. The role of CI in prognosis of the frailest patients with limited mobility is uncertain.The aim. To determine the influence of the initial cognitive status in the group of patronage patients aged 60 years and older on the risk of mortality within one year.Materials and methods. Study group consisted of 450 patients from patronage group with one-year period of observation (from July 2019 till July 2020). Initial physical, functional, neuropsychiatriac and social statuses were evaluated by comprehensive geriatric assessment. Cognitive impairment was screened by Mini-Mental State Examination (MMSE), with dividing patients into dementia group (MMSE ≤ 24) and no-dementia group (MMSE > 24). The mortality rate after one year was assessed.Results. Of the 450 patients included in the study, dementia was present in 44.2 %. Patients with dementia were more prone to greater severity of chronic pain, sleep disturbances, depression, malnutrition and anemia. After one year of observation 34 out of 196 patients (17.3 %) in the group of patients with dementia and 18 out of 248 patients (7.3 %; p = 0.002) in the no-dementia group died. According to multivariate analysis, independent risk factors for death in patients with dementia were anemia, hearing impairment and a history of bone fractures.Conclusion. Thus, the assessment of the cognitive status of frail patients with limited mobility is important for the purpose of identifying the most vulnerable individuals with a high risk of adverse outcomes.

Pre-operative anemia was associated with all-cause mortality in patients with vertebral fracture who underwent percutaneous vertebroplasty. Front Med (Lausanne) 2022; 9:1058636. [PMID: 36479098 PMCID: PMC9719986 DOI: 10.3389/fmed.2022.1058636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 11/07/2022] [Indexed: 08/30/2023] Open
Abstract
PURPOSE We investigated the association between pre-operative anemia and long-term all-cause mortality in patients with vertebral fracture who underwent a vertebroplasty. MATERIALS AND METHODS We retrospectively selected patients who were admitted for vertebroplasty for vertebral compression fracture between 2013 and 2020. Patients who had pathologic fractures or had no assessment of bone mineral density were excluded. Relevant information was collected from electronic medical records. Patients' survival status was confirmed at the end of March 2021. Cox-proportional hazard models were conducted to examine the effects of anemia (<12 g/dL vs. ≥12 g/dL) and pre-operative hemoglobin levels (as a continuous variable) on all-cause mortality with multivariate adjustments. RESULTS A total of 167 patients were analyzed (mean age 75.8 ± 9.3 years, male 25.7%). After a median follow-up duration of 2.1 years, pre-operative anemia (hemoglobin <12 g/dL vs. ≥12 g/dL) was independently associated with a higher risk of all-cause mortality (hazard ratio 2.762, 95% CI 1.184 to 6.442, p = 0.019). An increase in pre-operative hemoglobin was associated with a lower risk of all-cause mortality after multivariate adjustment (hazard ratio 0.775, 95% CI 0.606 to 0.991, p = 0.042). CONCLUSION Pre-operative anemia (<12 g/dL) was independently associated with survival outcome among patients with vertebral compression fractures who underwent vertebroplasty. Our findings highlight anemia as a risk factor of long-term mortality in this elderly surgical population.

Zhang H, Tian W, Sun Y. Development, validation, and visualization of a web-based nomogram to predict 5-year mortality risk in older adults with hypertension. BMC Geriatr 2022; 22:392. [PMID: 35509033 PMCID: PMC9069777 DOI: 10.1186/s12877-022-03087-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 04/20/2022] [Indexed: 11/16/2022] Open
Abstract
Background Hypertension-related mortality has been increasing in older adults, resulting in serious burden to society and individual. However, how to identify older adults with hypertension at high-risk mortality remains a great challenge. The purpose of this study is to develop and validate the prediction nomogram for 5-year all-cause mortality in older adults with hypertension. Methods Data were extracted from National Health and Nutrition Examination Survey (NHANES). We recruited 2691 participants aged 65 years and over with hypertension in the NHANES 1999-2006 cycles (training cohort) and 1737 participants in the NHANES 2007-2010 cycles (validation cohort). The cohorts were selected to provide at least 5 years follow-up for evaluating all-cause mortality by linking National Death Index through December 31, 2015. We developed a web-based dynamic nomogram for predicting 5-year risk of all-cause mortality based on a logistic regression model in training cohort. We conducted internal validation by 1000 bootstrapping resamples and external validation in validation cohort. The discrimination and calibration of nomogram were evaluated using concordance index (C-index) and calibration curves. Results The final model included eleven independent predictors: age, sex, diabetes, cardiovascular disease, body mass index, smoking, lipid-lowering drugs, systolic blood pressure, hemoglobin, albumin, and blood urea nitrogen. The C-index of model in training and validation cohort were 0.759 (bootstrap-corrected C-index 0.750) and 0.740, respectively. The calibration curves also indicated that the model had satisfactory consistence in two cohorts. A web-based nomogram was established (https://hrzhang1993.shinyapps.io/dynnomapp). Conclusions The novel developed nomogram is a useful tool to accurately predict 5-year all-cause mortality in older adults with hypertension, and can provide valuable information to make individualized intervention.
