Dapagliflozin and quality of life measured using the EuroQol 5-dimension questionnaire in patients with heart failure with reduced and mildly reduced/preserved ejection fraction.

AIMS: Although much is known about the usefulness of heart failure (HF)-specific instruments for assessing patient well-being, less is known about the value of generic instruments for the measurement of health-related quality of life (HRQL) in HF. The aim of this study was to assess the relationship between the EuroQol 5-dimension 5-level (EQ-5D-5L) visual analogue scale (VAS) and index scores, clinical characteristics, and outcomes in patients with HF and the effect of dapagliflozin on these scores. METHODS AND RESULTS: We performed a patient-level pooled analysis of the DAPA-HF and DELIVER trials, which investigated the effectiveness and safety of dapagliflozin in patients with HF and reduced ejection fraction (HFrEF) and mildly reduced/preserved ejection fraction (HFmrEF/HFpEF), respectively. Patients reporting higher (better) EQ-5D-5L VAS and index scores had a lower prevalence of comorbidities, including atrial fibrillation and hypertension, than patients with a worse score. They were also more likely to have better investigator-reported (New York Heart Association class) and patient-self-reported (Kansas City Cardiomyopathy Questionnaire) health status and lower median N-terminal pro-B-type natriuretic peptide levels. Compared to patients with the lowest scores (Q1), those with higher EQ-5D-5L VAS scores had better outcomes: the hazard ratio for the composite of cardiovascular death or worsening HF was 0.81 (95% confidence interval 0.72-0.91) in Q2, 0.74 (0.65-0.84) in Q3, and 0.62 (0.54-0.72) in Q4. The risk of each component of the composite outcome, and all-cause death, was also lower in patients with better scores. Similar findings were observed for the index score. Treatment with dapagliflozin improved both EQ-5D-5L VAS and index scores across the range of ejection fraction. CONCLUSIONS: Both higher (better) EQ-5D-5L VAS and index scores were associated with better outcomes. Dapagliflozin treatment improved EQ-5D-5L VAS and index scores, irrespective of ejection fraction.

D-index as a Risk Factor for Invasive Fungal Infections in Patients With Acute Lymphoblastic Leukemia From a Reference Hematology Center in Bogota.

Introduction Patients with hematologic malignancies are susceptible hosts for the development of invasive fungal infection (IFI), one of the main life-threatening infectious complications faced by these patients. Currently, we have antifungal prophylaxis strategies and antifungal treatment schemes and we recognize that the main risk factor involved is profound and prolonged neutropenia. D-index and cumulative D-index are quantitative parameters, which determine the magnitude of neutropenia, as a function of duration and depth and their value correlates with the occurrence of IFI. Material and methods A case-control study in patients older than 18 years with acute lymphoblastic leukemia (ALL) was admitted between 2009 and 2019 at the National Cancer Institute for induction, consolidation and salvage chemotherapy. Results A total of 167 patients were included, who received 288 cycles of chemotherapy, the latter were considered the unit of analysis. A generalized estimating equations (GEE) model was designed to analyze correlated data; three quantitative and continuous variables of interest were included in this model: age (years), D-index and deep neutropenia (days). For the population D-index, an odds ratio (OR) = 1.000227 (95% CI 1.0002-1.0004); p < 0.001 was obtained. Conclusion D-index is associated with the development of IFI in patients with ALL, with an exponential increase in OR as the absolute value of the D-index increases.

Serial platelet level index improves prediction of pulmonary hemorrhage in patients with Stenotrophomonas maltophilia respiratory infections and thrombocytopenia.

Patients with thrombocytopenia (platelet count <150 × 103/µL) often develop pulmonary hemorrhage (PH) after Stenotrophomonas maltophilia (SM) respiratory infection, resulting in a high respiratory failure rate and increased mortality. Developing an efficient method for early prediction of PH in these patients may improve survival. This study aimed to evaluate risk factors in PH and to develop an index measuring serial platelet deficit to predict PH in patients with SM respiratory infection. Data of patients with SM respiratory infection and thrombocytopenia treated in a tertiary university hospital during 2018-2020 were retrospectively retrieved from electronic medical records and analyzed. SM respiratory infection was defined as SM isolated from sputum, endotracheal suction, or bronchial alveolar lavage plus acute respiratory symptoms. Between PH and non-PH groups, clinical characteristics and laboratory parameters were collected and compared. The newly developed platelet dissimilarity index (d-index) was calculated by accumulating differences between the actual and the lowest normal level of the platelet count in each patient at different time points. Within 1,039 patients with positive SM culture, 437 cases matched the criteria and were analyzed. A total of 125 (28.6%) patients developed PH and 312 (71.4%) did not. The patients with PH had increased prothrombin time/international normalized ratio (PT/INR), lower platelet count, and higher platelet d-index. Multivariate analysis revealed that extreme thrombocytopenia (platelet count <50 × 103/µL) is a common independent risk factor in PH and mortality. The performance of platelet deficit and d-index varied between patients with different comorbidities. Performance of platelet deficit to predict PH is better in patients with hematology/oncology or liver disease (area under curve, 0.705-0.757), while d-index is better in patients with sepsis/treatment and various other groups (0.711-0.816). Prolonged and extreme thrombocytopenia is a determinant risk factor in PH in patients with SM respiratory infection. Given the complexity of causes of thrombocytopenia and associated comorbidities, different strategies should be applied when assessing the risk for PH.

Effect of the COVID-19 pandemic on depression in older adults: A panel data analysis.

BACKGROUND: This paper investigates the impact of the COVID-19 pandemic on depression in the older population, an especially vulnerable group for which to date there is limited empirical research. METHODS: We employ a panel data consisting of seven waves of the English Longitudinal Study of Ageing (2010-2020). The breadth and depth of the data considered enabled us to control for individual fixed effects, to adjust for pre-pandemic trends in depression levels and to perform a heterogeneity analysis, depending on the intensity of the lockdown measures implemented and relevant socioeconomic characteristics. RESULTS: We find that, following the COVID-19 pandemic, study participants reported a statistically significant increase in the depressive symptoms by around 0.7 over 8 points as measured by the Centre for Epidemiologic Studies Depression (CES-D) index. The estimated coefficients were larger in November than in July, for individuals who lost their job, retired and women. Interestingly, we observed that mental health has worsened substantially relative to the pre-pandemic period across all income groups of the older population, suggesting a limited role of income as a protective mechanism for mental health. CONCLUSIONS: Our findings provide compelling evidence that depression levels amongst older adults have worsened considerably following the COVID-19 pandemic, and that factors other than income, such as social interactions, may be highly relevant for well-being in later life.

Validation of the multi-metric D-index change in the assessment of keratoconus progression.

PURPOSE: To validate the effectiveness of the multi-metric D-index by Pentacam in detecting keratoconus (KC) progression. MATERIALS AND METHODS: This was a retrospective study of KC patients at the Rabin Medical Center, Petah Tikva, Israel, during 2016-2018 with at least two corneal tomography examinations six months apart. Agreement between clinical diagnosis of progression (1.5D increase in mean keratometric value, 1D increase in Kmax, a 5% decrease in central corneal thickness (CCT), worsening of visual acuity by more than one line, or deterioration of manifest corneal astigmatism > 1.5D) and the D-index was evaluated. Receiver operating characteristic (ROC) analysis was used to find the D-index's optimal cutoff value to show progression. RESULTS: We included KC eyes in the stable group (N = 7) and the progression group (N = 54). Patient demographics and tomographic parameters at baseline were similar between the groups. The D-index change was significantly higher in the progression group than in the stable group (median + 1 and 0.0, respectively, p = 0.024). Based on the ROC analysis, the optimal D-index cutoff change within at least six months was 0.32 (59.3% sensitivity and 100% specificity (area under the curve [AUC] = 0.771, Youden = 0.592). Subjects with a D-index change above this value had a 21.1-fold increase in odds for corneal ectasia progression requiring CXL (OR: 21.1, 95%CI 1.17-398.8, p = 0.038). CONCLUSION: The multi-metric D-index can serve as a clinically feasible parameter to detect KC progression and guide patients' referral for further interventions.

High D-index during mobilization predicts poor mobilization of CD34+ cells after anti-lymphoma salvage chemotherapy.

BACKGROUND: Performing stem cell collection after mobilization chemotherapy was a well-balanced strategy between anti-tumor effect and efficient collection of CD34+ cells, but deep and prolonged nadir exposed patients to risk of febrile neutropenia. Febrile neutropenia was known to be associated with lower yields of CD34+ cells, but quantitative data referring to association between yields of CD34+ cells and severity of neutropenia was lacking. We hypothesized that D-index, which was developed for quantitative evaluation of severity of neutropenia especially in the field of hematologic malignancies, could predict yields of CD34+ cells. METHODS: We performed a single center, retrospective analysis of patients with relapsed or refractory aggressive lymphoma who were mobilized with ESHAP or modified ESHAP. We evaluated the association between yields of CD34+ cells at first apheresis and D-index. RESULTS: Thirty-six patients were included, and we demonstrated that yields of CD34+ cells from patients with higher D-index were significantly lower than those from patients with lower D-index. Multivariate linear regression analysis and logistic regression analysis also demonstrated the significant predictive power of D-index. Further, D-index was significantly correlated to platelet count before starting mobilization chemotherapy. Platelet count was known to predict yields of CD34+ cells, and combination of platelet count and D-index could identify patients with lowest CD34+ yields. CONCLUSION: D-index could predict yields of CD34+ cells and it seemed that its predictive power was not less than that of platelet count. Prospective studies including more heterogeneous patients were needed to validate our study.

Avaliação do estado nutricional em relação à presença de cárie dentária em crianças de 4 a 6 anos do município de Cajamar - São Paulo / Evaluation of the nutritional status in relation to the presence of dental caries in children aged 4 to 6 years in the city of Cajamar - São Paulo

Este artigo tem como objetivo avaliar o estado nutricional em relação à presença de cáries dentárias em crianças de 4 a 6 anos de idade, do município de Cajamar, São Paulo. Trata-se de estudo transversal com crianças entre 4 a 6 anos (n=1642), acompanhadas pelo Programa Saúde na Escola (PSE) do Município de Cajamar, São Paulo. A classificação do estado nutricional foi baseada no Índice de Massa Corporal (IMC) e a avaliação das condições bucais, por meio do índice ceo-d e critério para Risco de Cárie. A análise do estado nutricional, faixa etária e sexo conforme o número de cáries, foi feita por meio dos testes Mann-Whitney U e Kruskal-Wallis (p<0,05). Observou-se maior prevalência de meninos entre 4 a 6 anos. Em todas as faixas etárias a prevalência de excesso de peso foi de aproximadamente 30% e eutrofia em torno de 70%. 65% (n=1068) das crianças não apresentavam risco de cárie (A) e 28,8% (n=475), alto risco (D, E e F). Das 1162 crianças sem cáries, 0,2% eram magras (n=2), 67,2% (n=781) eutróficas e 32,7% (n=380) possuíam excesso de peso. A frequência de 1 a 5 cáries maior entre meninas e de 6 ou mais cáries, entre meninos. Segundo estado nutricional, o número médio do número de cáries foi de 2,17 para magreza, 0,93 para eutrofia e 0,65 para excesso de peso (p<0,010). Conclui-se que houve diferença entre número cáries e estado nutricional, na qual crianças com déficit nutricional apresentavam maior número de cáries dentárias comparadas às eutróficas ou com excesso de peso, sugerindo-se a inclusão do estado nutricional na avaliação odontológica.

This article aims at evaluating the nutritional status in relation to the presence of dental caries in children aged 4 to 6 years in the city of Cajamar, in the state of São Paulo. It is a cross-sectional study with children aged 4 to 6 years (n=1642) accompanied by the School Health Program of the City of Cajamar, São Paulo. The nutritional status classification was based on the Body Mass Index (BMI) and the evaluation of oral conditions, through the ceo-d index, and criteria for risk for caries. The analysis of the nutritional status, age, and sex according to the number of caries was made through the Mann-Whitney U and Kruskal-Wallis tests (p<0.05). A higher prevalence was observed among boys aged 4 to 6 years. In all age groups, there was a prevalence of 30% of overweight children, and eutrophy of approximately 70%. A total of 65% (n=1068) of the children presented no risk of caries (A), whereas 28.8% (n=475) showed high risk (D, E, and F). Among the 1162 children with no caries, 0.2% were thin (n=2); 67.2% (n=781) eutrophic; and 32.7% (n=380) were overweight. Girls presented a higher frequency of 1 to 5 caries while boys presented frequency of having 6 or more caries. According to the nutritional status, the average number of caries was 2.17 for thin individuals; 0.93 for eutrophic individuals; and 0.65 for overweight individuals (p<0.010). It could be concluded that there was a difference between the number of caries and the nutritional status, in which children with nutritional deficit presented a higher number of dental caries when compared to eutrophic or overweight ones, suggesting the inclusion of the nutritional status in the dental evaluation.

A Powerful Nomogram Based on the Novel D-Index to Predict Prognosis After Surgical Resection of Hepatocellular Carcinoma.

PURPOSE: Conventional staging and scoring systems such as the Tumor, Node, and Metastasis; Cancer of the Liver Italian Program; Barcelona Clinic Liver Cancer; and Okuda have failed to predict overall survival (OS) in patients with resected primary hepatocellular carcinoma. Thus, we aimed to establish a novel D-index and nomogram to improve prognostic accuracy. PATIENTS AND METHODS: We selected 396 patients who underwent liver resection between January 2007 and February 2015 at the First Affiliated Hospital of Wenzhou Medical University. These patients were randomly divided into the training and validation groups in a ratio of 7:3. RESULTS: We generated a nomogram using five independent risk factors, including the D-index (calculated by total bilirubin × tumor size/the ratio of fat-to-muscle area 0.5) in the training set. The predictive performance of the nomogram was similar in both the training and validation cohorts according to the concordance index. The nomogram demonstrated the strongest predictive power for 1-year, 3-year, and 5-year OS, with the area under the receiving operating characteristic curve being 0.8486, 0.7785, and 0.752, respectively. The calibration curves exhibited stable capabilities in both cohorts. The stratification of the Kaplan-Meier curve was significant (P < 0.001). CONCLUSION: The associated nomogram of the D-index demonstrated a powerful and accurate predictive ability for OS in patients with primary hepatocellular carcinoma.

D-index as a marker of bloodstream infections in patients with allogeneic hematopoietic stem cell transplantation.

BACKGROUND: Neutropenia is a risk factor for development of infections; however, the direct effect of neutropenia on development of bloodstream infection (BSI) is not known. D-index, which is area between the neutrophil time curve and a neutrophil count of 0.5 × 109 /L, incorporates the combined effect of severity and duration of neutropenia. We aimed to evaluate whether D-index can be used as a marker for BSI in patients with allogeneic stem cell transplantation. METHOD: We conducted a retrospective cohort study of patients undergoing allogeneic stem cell transplantation between January 1, 2005, and September 30, 2015. The primary outcome measure was the development of BSI within 30 days of transplantation. RESULTS: A total of 714 patients were included in the study of whom 101 developed BSI. Patients with BSI had a significantly higher median D-index value compared with patients who did not have BSI (4990 vs. 3570, P < .001). As a marker, the performance of the D-index was similar to that of the duration of profound neutropenia (P = .18) and significantly better than the total duration of neutropenia (P = .001). CONCLUSION: The D-index performed better than the total duration of neutropenia as a marker for BSI in patients with allogeneic stem cell transplantation. There was no difference between D-index and, a more easily calculable indicator, duration of profound neutropenia.

Comparison of myelosuppression using the D-index between children and adolescents/young adults with acute lymphoblastic leukemia during induction chemotherapy.

BACKGROUND: Adolescents and young adults (AYAs) with acute lymphoblastic leukemia (ALL) are more likely to have chemotherapy-related complications than children. In addition, several reports have shown that infections account for most of the therapy-related mortality during cancer treatment in AYAs. Thus, we hypothesized that chemotherapy-induced myelosuppression is more severe in AYAs than in children, and the state of neutropenia was compared between children and AYAs using the D-index, a numerical value calculated from the duration and depth of neutropenia. PROCEDURE: This study retrospectively analyzed 95 patients newly diagnosed with ALL at our institution between 2007 and 2019. Of these, 81 were children (<15 years old) and 14 were AYAs (≥15 years old). The D-index and duration of neutropenia during induction chemotherapy for ALL were compared between children and AYAs. RESULTS: The median D-index of children was significantly higher than that of AYAs (8187 vs 6446, respectively, P = .017). Moreover, the median duration of neutropenia was also significantly longer in children than in AYAs (24.0 days vs 11.5 days, respectively, P = .007). CONCLUSION: Contrary to our expectations, myelosuppressive toxicity during induction chemotherapy for ALL was more severe in children than in AYAs.

Efficacy and safety of micafungin in empiric and D-index-guided early antifungal therapy for febrile neutropenia; A subgroup analysis of the CEDMIC trial.

OBJECTIVES: The D-index is defined as the area over the neutrophil curve during neutropenia. The CEDMIC trial confirmed the noninferiority of D-index-guided early antifungal therapy (DET) using micafungin to empirical antifungal therapy (EAT). In this study, we evaluated the efficacy and safety of micafungin in these settings. METHODS: From the CEDMIC trial, we extracted 67 and 113 patients who received micafungin in the DET and EAT groups, respectively. Treatment success was defined as the fulfilment of all components of a five-part composite end point. Fever resolution was evaluated at seven days after the completion of therapy. RESULTS: The proportion of high-risk treatments including induction chemotherapy for acute leukemia and allogeneic hematopoietic stem cell transplantation was significantly higher in the DET group than in the EAT group (82.1% vs. 52.2%). The efficacy of micafungin was 68.7% (95%CI: 56.2-79.4) and 79.6% (71.0-86.6) in the DET and EAT groups, respectively. When we focused on high-risk treatments, the efficacy was 69.1% (55.2-80.9%) and 78.0% (65.3-87.7%), respectively (P = 0.30). There was no significant difference in any of the 5 components between the two groups. CONCLUSIONS: The efficacy of micafungin in patients undergoing high-risk treatment was not strongly impaired in DET compared to that in EAT.

Responsiveness of Vision-Specific and General Quality of Life Metrics to Ocular and Systemic Events in Patients with Uveitis.

PURPOSE: To evaluate the responsiveness of quality of life (QoL) metrics to ocular and systemic events in patients with noninfectious uveitis. DESIGN: Cohort study using randomized controlled trial data. PARTICIPANTS: Patients with active or recently active intermediate, posterior, or panuveitis enrolled in the Multicenter Uveitis Steroid Treatment (MUST) Trial and Follow-up Study. METHODS: Data on the 25-item National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25), EuroQol Questionnaire (EQ-5D), and Short Form Survey Instrument (SF-36) were evaluated semiannually during the first 3 years after randomization. The impact of ocular (e.g., changes in visual acuity [VA], activity status, cataract surgery) and systemic events (e.g., infections requiring treatment) on the 6-month changes in QoL was assessed for each metric using generalized estimating equations. MAIN OUTCOME MEASURES: The primary outcomes were the 6-month changes in vision-related (NEI-VFQ-25) and general health-related (EQ-5D index, SF-36 physical component summary [PCS]) QoL. RESULTS: Changes in VA (adjusted change [aΔ]: 2.70 units per 5 letter change, P < 0.001), implant placement in at least 1 eye (aΔ: 5.50, P < 0.001), cataract surgery (aΔ: 3.01, P = 0.017), and quieting of all eyes active at the beginning of the interval (aΔ: 2.20, P < 0.010) were associated with improvements in the NEI-VFQ-25. Reductions in VA (aΔ: -0.014 per 5 letter decline, P = 0.003), infections requiring a prescription (aΔ: -0.024, P = 0.021), and incident uveitis activity in at least 1 eye (aΔ: -0.023, P = 0.031) were associated with declines in the EQ-5D index. Hospitalization (aΔ: -2.24, P = 0.019), infections requiring a prescription (aΔ: -1.00, P = 0.024), and vitreous hemorrhage in at least 1 eye (aΔ: -1.92, P = 0.021) were associated with declines in the SF-36 PCS. Declines in VA, initiation in IOP medication, and age were associated with changes in SF-36 PCS; however, the magnitude of the change was less than a single point. CONCLUSIONS: The NEI-VFQ-25 was more sensitive to ocular changes than the general QoL metrics but less sensitive to acute systemic events. When performing QoL or cost-effectiveness analyses, it is important to consider the expected outcomes (e.g., ocular vs. systemic) to ensure that the selected measurement is sensitive enough to detect clinically important changes in disease status or effects of treatment.

Impact of neutropenia evaluated in terms of the D-index on invasive fungal disease while on empiric or preemptive antifungal treatment strategy in the early phase after allogeneic hematopoietic stem cell transplantation.

BACKGROUND: We retrospectively evaluated the association between the D-index, which reflects both the depth and duration of neutropenia, and proven/probable invasive fungal disease (IFD) early after allogeneic hematopoietic stem cell transplantation (HSCT) at our center (n = 394). METHODS: The D-index was defined as the area over the neutrophil curve during neutropenia. The cumulative D-index from the start of neutropenia until the development of infection (c-D-index) was also evaluated as a real-time assessment of neutropenia. RESULTS: There were 19 cases of early proven/probable IFD before and within 1 week after engraftment. Fifteen cases (78.9%) were seen as breakthrough infection while on empiric (n = 7), preemptive (n = 4) or prophylactic (n = 4) antifungal administration with mold-active agents. The c-D-index and lower performance status were identified as independent significant predictive factors for IFD. A receiver operating characteristic (ROC) curve analysis showed that the D-index and c-D-index were more accurate than the simple duration of neutropenia and as accurate as the duration of profound neutropenia for predicting IFD. The sensitivity, specificity, and positive and negative predictive values of the c-D-index using an appropriate cutoff (CO) value (10 644) determined by ROC curve analysis were 73.1%, 63.2%, 9.1%, and 97.9%, respectively. The advantage of the c-D-index to cumulative days of neutropenia in terms of positive and negative predictive values seemed to be small. CONCLUSIONS: The appropriate CO value for the c-D-index for predicting IFD was as high as 10 644 in allogeneic HSCT with a more frequent use of empiric antifungal therapy. The c-D-index is useful for assessing the risk of breakthrough IFD.

CT of invasive pulmonary aspergillosis (IPA) in cases with hematologic malignancy: Comparison of CT features in the group classified by the severity of neutropenia and underlying disease.

PURPOSE: To identify differences in the radiological findings of invasive pulmonary aspergillosis (IPA) among patients classified by severity of neutropenia, and differences in underlying disease. MATERIALS AND METHODS: We retrospectively reviewed computed tomography (CT) scans from the time of the diagnosis of IPA in 83 hematological malignancy patients with probable or proven IPA according to the EORTC-MSG criteria. We evaluated CT findings (radiological pattern, number of lesions, distribution, and presence of low attenuation area [LAA]), and compared the radiological findings of patients classified by degree of neutropenia with two different indicators (neutrophil count at the onset, and c-d-index) and underlying disease. RESULTS: Neutropenia at the onset of IPA was associated with an increased frequency of LAA (p < 0.05), especially in FN (p < 0.01). Cases with a c-d-index of ≧5500 showed an increased incidence of the angio-invasive pattern. In contrast, cases with a c-d-index of 0 showed an increased incidence of the airway-invasive pattern (p < 0.05). The airway-invasive pattern was more frequent in cases with MM, while the angio-invasive pattern was more frequent in cases with AML (p < 0.01). Lower-predominant distribution was more frequent and random distribution was less frequent in cases with AML, random distribution was more frequent and lower-predominant distribution was less frequent in cases with ALL, and upper-predominant distribution was more frequent in cases with MDS (p < 0.05). CONCLUSIONS: CT features of IPA vary according to the degree of neutropenia and underlying disease.

Factors associated with health-related quality of life and burden on relatives of older people with multi-morbidity: a dyadic data study.

BACKGROUND: This study aimed to identify factors associated with health-related quality of life (HRQoL) and the burden on the relatives of older people with multi-morbidity. METHODS: A secondary analysis of baseline data from 296 dyads, including older patients with multimorbidity and their relatives, which were previously collected in a randomized study. The analysis was conducted to select correlated independent variables to enter a final linear regression analysis of two models with different endpoints: the relatives' HRQoL (EQ5D index) and burden (COPE index: Negative impact scale). RESULTS: Sixteen variables correlated with the relatives' HRQoL, and 15 with the relatives' burden. Both the HRQoL and burden correlated with both patient and relative variables. A high HRQoL was associated with relatives' working/studying. A high burden was associated with caring for an older person with changed behaviour. A low burden was associated with the relatives' high scores on positive values of caring, quality of support and HRQoL. CONCLUSION: Older persons and their relatives should be considered as a unit in the development of support of older people in order to increase the health and quality of life of both groups. To support and protect relatives from a high burden, potential measures could include improving the relative's HRQoL and strengthening their ability to find positive values in care and strengthening reliable and good support from others. The relatives' HRQoL explained the variation in the burden. However, the burden did not explain the variation in the HRQoL, which suggests that the relatives' HRQoL is not so readily affected by their burden, whereas the relatives' HRQoL can influence their burden. The variables used in the regression analyses where chosen to reflect important aspects of the relatives' and older persons' situations. The final models explained 38% of the variation in the relatives' burden but only 10% of the variation in their HRQoL. This could be important to consider when choosing outcome assessments in future studies.

Measurement of health-related quality of life in patients with diabetes mellitus using EQ-5D-5L in Hong Kong, China.

PURPOSE: This study aimed to estimate the health preference scores of the Chinese population with Diabetes Mellitus (DM) using the EQ-5D-5L Hong Kong (HK) population tariff according to different sociodemographic characteristics in HK. METHODS: Data were obtained from a cross-sectional, territory-wide study of patient experience on specialist outpatient services in a public setting in HK. The EQ-5D-5L HK was used to collect the patients' health status. A total of 2326 respondents were reported to suffer from DM, and their information was elicited and used for the analysis in this study. A robust ANOVA method was used to compare the differences in EQ-5D-5L index scores among subgroups. Binary logistic regressions were used to predict the probability of respondents reporting full health, and ordinal least square (OLS) model was used to assess the relationship between DM and health-related quality of life (HRQoL). RESULTS: The mean EQ-5D-5L index score for DM patients was 0.84. A total of 229 EQ-5D health states were reported. Altogether, 47.5% of the respondents reported having some problems with pain/discomfort, followed by mobility (26.4%), usual activities (26.0%), and anxiety/depression (23.5%). Logistic regression and OLS models indicated that male and fully employed respondents were less likely to report having problems with any of the five dimensions and index score of EQ-5D than female and non-fully employed respondents. The findings of OLS model also showed that DM patients that experience comorbidity with three and more chronic conditions were more likely to show a lower index score than respondents who reported living with DM alone. CONCLUSION: The EQ-5D index scores varied among DM patient characteristics and were more highly impaired with multimorbidity status. Interventions targeting at-risk subgroups, such as modifying single-diseased guidelines, might be helpful to improve their HRQoL.

No effect of tourniquet in primary total knee arthroplasty on muscle strength, functional outcome, patient satisfaction and health status: a randomized clinical trial.

PURPOSE: Tourniquet use during primary total knee arthroplasty (TKA) may negatively impact the early postoperative functional recovery due to molecular effects of ischaemia. The hypothesis of the present study was that primary TKA without a tourniquet positively influences the postoperative muscle strength, functional outcome, patient satisfaction and health status. METHODS: The monocentric, randomized, controlled trial included a total of 99 patients scheduled to undergo primary TKA (ClinicalTrials.gov NCT02475603). The patients were randomly assigned to the tourniquet (n = 50) or non-tourniquet (n = 49) group after receiving a written informed consent. As primary outcome parameter, the functional outcome, patient expectation/satisfaction and the health status were assessed preoperatively, 6 weeks, 6 months postoperatively using Oxford knee score, WOMAC score, Mancuso score, EQ-5D index, EQ-VAS, anxiety score, depression score, hospital anxiety and depression scale, respectively. Additionally, a rope pulley isokinetic system (Moflex, Recotec/Bernina, Switzerland) was applied to quantify the muscle strength preoperatively, 1 week, 6 weeks and 6 months postoperatively. RESULTS: No difference in any of the outcome parameters could be observed between the groups at all time points after TKA (n.s.). Also the isokinetic muscle strength of the knee joint as quantified by concentric/eccentric peak force (N), workload (J), total workload (J) and power (W) did not reveal statistically significant differences between the groups and time points. However, in both groups improved results were found with respect to the functional outcome, patient satisfaction, health status and isokinetic muscle strength up to 6 months postoperatively. CONCLUSIONS: The application of the tourniquet did not affect the isokinetic muscle strength, the functional outcome, the patient satisfaction and the health status following primary TKA. However, with and without tourniquet use, the level of the knee functionality, the patient satisfaction as well as the health status improved significantly. LEVEL OF EVIDENCE: I.

The D-index is not correlated with invasive fungal infection during the early-post engraftment phase among allogeneic hematopoietic stem cell transplant recipients.

The D-index assesses neutropenia dynamics. Prolonged neutropenia is a major risk for invasive fungal infection (IFI); we hypothesized that D-index is predictive of IFI risk. We retrospectively reviewed 789 adults who underwent allogeneic hematopoietic transplant (HSCT) from 1/1/2005 to 9/30/2015. Medical records were reviewed from transplant (D0) through Day 100. The D-index was calculated as area over the neutrophil curve until engraftment. 714 patients were included for analysis. Sixteen (2%) developed probable (11) or proven (5) IFI. Median time to IFI was 40 days (range 8-98) after HSCT. Groups with and without IFI did not differ significantly in duration of mild or profound neutropenia. Median D-index of those with IFI was 4293 days neutrophil/µl compared to 3590 days neutrophil/µl for those without IFI (P = 0.17). Patients who were neutropenic on D0 showed higher rates of IFI than those who were not (10/123 [8%] vs 6/591 [1%]; P < 0.001). Only 2% developed IFI, likely due to mold-active antifungal prophylaxis. The D-index was not significantly higher in those with IFI. Duration of profound neutropenia and neutropenia at D0 may be better markers for IFI among HSCT recipients during the first 30 and 100 days after transplant.

Low-Cost 2D Index and Straightness Measurement System Based on a CMOS Image Sensor.

Accurate traceable measurement systems often use laser interferometers for position measurements in one or more dimensions. Since interferometers provide only incremental information, they are often combined with index sensors to provide a stable reference starting point. Straightness measurements are important for machine axis correction and for systems having several degrees of freedom. In this paper, we investigate the accuracy of an optical two-dimensional (2D) index sensor, which can also be used in a straightness measurement system, based on a fiber-coupled, collimated laser beam pointing onto an image sensor. Additionally, the sensor can directly determine a 2D position over a range of a few millimeters. The device is based on a simple and low-cost complementary metal-oxide-semiconductor (CMOS) image sensor chip and provides sub-micrometer accuracy. The system is an interesting alternative to standard techniques and can even be implemented on machines for real-time corrections. This paper presents the developed sensor properties for various applications and introduces a novel error separation method for straightness measurements.
