Highly specific functional equivalence of XN-HPC for optimum CD34+ cell count in harvested allogeneic bone marrow stem cell products

Hematology. 2022 Dec;27(1):232-238. doi: 10.1080/16078454.2022.2030884.

ABSTRACT

OBJECTIVES: To establish a reliable XN-HPC cutoff, for an effective CD34 + cell count of ≥2 × 106cells/kg of the recipient’s body weight, in harvested bone marrow products in allogenic transplantation.

METHODS: The study was carried out in two phases. In retrospective Phase 1, data from 47 donors were analyzed. Sysmex analyzer XN-20 and BD FACS Calibur were employed to process XN-HPC and CD34 + cell enumeration, respectively. To make the two variables comparable, both XN-HPC and CD34 + cell counts were reported as the number of cells/kg of the recipient’s body weight. Spearman’s rank correlation coefficient was calculated for CD34 + cells and XN-HPC, followed by the calculation of the receiver operating characteristic (ROC) curve to identify the XN-HPC value which could effectively predict the cutoff of ≥2 × 106 CD34 + cells/kg of the recipient’s body weight. In Phase 2, the computed XN-HPC cutoff was validated in a prospective set of 53 donors by obtaining the positive and negative predictive values.

RESULTS: Statistically significant correlation was obtained between XN-HPC and CD34 + cell count with Spearman’s rho of 0.54 (p-value <0.001). The optimal XN-HPC cutoff, for the required CD34 + ve cell count of ≥2 × 106 cells/kg of the recipient’s body weight, was calculated to be ≥2.80×106 cells/kg of the recipient’s body weight with the specificity and sensitivity of 100% and 31%, respectively. The ROC curve demonstrated the area under the curve to be 0.74. Phase 2 validation revealed 100% PPV.

CONCLUSIONS: For harvested bone marrow products with XN-HPC of ≥2.80×106 cell/kg of the recipient’s body weight, CD34 + cell enumeration by flow cytometry can safely be disposed of.

The Tuokko version of the Clock Drawing Test: A validation study in the Greek population

J Clin Exp Neuropsychol. 2022 Feb 12:1-13. doi: 10.1080/13803395.2022.2036706. Online ahead of print.

ABSTRACT

INTRODUCTION: The present study aims to be the first to validate the Tuokko version of the Clock Drawing Test (CDT) and estimate its cutoff score after its translation into the Greek language and administration in the Greek population.

METHODS: One hundred and thirty-two individuals participated in this study [60 with Good Cognitive Health (GCH), 24 with Parkinson’s Disease (PD), 24 with Parkinson’s Disease Dementia (PDD) and 24 with Alzheimer’s Disease (AD)]. The CDT was administered to all participants. Additionally, the cognitive and mental status of the sample were estimated through the use of the Mini Mental State Examination (MMSE), Abbreviated Mental Test Score (AMTS), Arizona Battery for Communication Disorders of Dementia (ABCD), Instrumental Activities of Daily Living (IADL), the Neuropsychiatric Inventory (H-NPI) and the Geriatric Depression Scale -15 (GDS-15).

RESULTS: Statistically significant differences were found between all groups on the CDT, with AD patients having lower scores than all subgroups in the study. The CDT showed a high internal consistency (Cronbach’s alpha = 0.832). The ROC analysis provided a cutoff point equal to 4.00 (AUC: 0.821, p < 0.001) between the Cognitively Unimpaired Group (CUG: GCH and PD group) and the Cognitively Impaired Group (CIG: PPD and AD patients), 5.00 (AUC: 0.845, p < 0.001) between the GCH group and the PDD group, and 4.00 (AUC: 0.780, p < 0.001) between the GCH group and the AD group. Finally, the cutoff point between the PD group and the PDD group was 4.00 (AUC: 0.896, p < 0.005), and 3.00 (AUC: 0.899, p < 0.001) between the PD group and the AD group. Significant positive Pearson’s correlations were observed between CDT and MMSE (r = 0.808, p < 0.001), CDT and AMTS (r = 0.688, p < 0.001), CDT and ABCD (r = 0.770, p < 0.001), CDT and the ABCD Visuospatial Construction subdomain (r = 0.880, p < 0.001); while a negative correlation was found between CDT and IADL (r = -0.627, p < 0.001) between the CUG and the CIG groups.

CONCLUSION: Given the results obtained, the CDT appears to be a clinically valid screening instrument for the assessment of visuospatial abilities, with high reliability in Greek populations with cognitive impairment.

Effect of elemental composition assigned to antrotopic pollution on the quality of the water and sediment of the Marrecas river (PR, Brazil) as highlighted by multivariate statistical analyses

J Environ Sci Health A Tox Hazard Subst Environ Eng. 2022 Feb 14:1-15. doi: 10.1080/10934529.2022.2039551. Online ahead of print.

ABSTRACT

In recent years, several environmental pollutants have been monitored in surface waters and sediments. However, few studies apply multivariate statistics to identify the main components and correlate them temporally and spatially. In this sense, the present study sought to monitor the quality of water and sediments in the Rio Marrecas/Brazil, through the analysis of physicochemical parameters and trace elements, as well as to identifying sources of contamination, using multivariate statistics. For this purpose, sampling was carried out in nine locations for a period of 12 months. The Total Reflection X-ray Fluorescence (TXRF) technique was used to quantify the 15 elements identified in water and sediment samples. Through multivariate statistical analyses, the most significant elements, their correlations and possible pollutant sources were defined, and the pollution index (HPI) and assessment index (HEI) of heavy metals were applied. The parameters pH and BOD5 do not comply with Brazilian legislation. Based on PCA and Spearman correlation, there was strong evidence of contamination of the water naturally, composed of the elements Ti, V, Mn, Fe, and of anthropogenic origin composed of the elements Ca, Ni, Cu, Zn. These findings provide insights to determine the impacts of heavy metals on human health and the environment.

The impact of COVID-19 lockdown on the general health status of people with chronic health conditions in Belgium: a cross-sectional survey study

Physiother Theory Pract. 2022 Feb 12:1-16. doi: 10.1080/09593985.2022.2036278. Online ahead of print.

ABSTRACT

BACKGROUND: Patients with chronic health conditions risk aggravation of their health status due to reduced access to health services during the COVID-19 related lockdown.

OBJECTIVES: To investigate the impact of Belgian COVID-19 measures on general health status (i.e. worse or stable/better) of patients, adult and pediatric, with chronic health conditions and how this change in health status relates to personal and health behavior-related factors.

DESIGN: A cross-sectional study using an online survey was conducted during the first COVID-19 related lockdown in Belgium.

METHODS: Associations between change in health status since the lockdown and (change in) personal and health behavior-related factors (including physical activity, access to health-care services and social activities) were investigated.

RESULTS: In adults (n = 561), almost all personal factors, including feelings of distress, depression, anxiety, somatization, and low self-efficacy, were significantly worse in patients with a worse health status during the lockdown (n = 293, 52%) compared to patients reporting a stable/better health status (p < .001-0.002). Also, these patients reported lower physical activity levels, more tele-consultations and less social activities (p < .001-0.006). In children (n = 55), all surveys were completed by a proxy (parent(s)/guardian) who reported a worse health status in 38% of the children. Level of distress of the child (p = .005) since the lockdown and somatization of the parent(s) (p = .0018) were significantly worse in children with a worse versus a stable/better health status.

CONCLUSION: Fifty-two percent of the adults and 38% of children with chronic health conditions reported worsening of their general health status during the lockdown in March-May 2020 in Belgium. Negative personal factors and unhelpful health behavior seems to be associated with a worse health status.

Therapeutic climbing in Parkinson’s disease: Differences in self-reported health and well-being, feasibility and clinical changes

Physiother Theory Pract. 2022 Feb 12:1-15. doi: 10.1080/09593985.2022.2036279. Online ahead of print.

ABSTRACT

BACKGROUND: Therapeutic climbing (TC) is a whole-body workout that stimulates and improves physical and psychosocial abilities. It has been used in neurological rehabilitation, but there is scarce evidence of specific benefits for people with Parkinson’s (PwP).

OBJECTIVE: To investigate and evaluate self-reported differences in health and well-being among trial participants, the overall feasibility of TC and clinical changes caused as a rehabilitation measure for PwP.

METHODS: A 3-level Likert scale survey was completed by 26 PwP (100% response rate) after a TC course (mean 16 sessions) at the Neurological Rehabilitation Center assessing self-perceived differences in health and well-being in terms of physical, psychological, and social parameters. We investigated the feasibility of TC in terms of adherence, practicability and acceptability during a multidisciplinary inpatient rehabilitation program and determined several clinical outcomes (10-meter distance and 2-minute duration walking tests, Functional Gait Assessment, Nine-Hole-Peg tests, and Tinetti Assessment Tool).

RESULTS: Improvements are based on self-reported perceptions of PwP. We observed an improvement of overall physical (average 65%), psychological (average 59%) and social (average 39%) aspects after TC. PwP improved strength (96%), balance (88%), range of motion (88%), body awareness (85%), physical well-being (77%), and fatigue (75%). Furthermore, they self-reported admiration in their social surrounding (42%) and felt more sociable and outgoing (40%). Concerning adherence, practicability and acceptability, TC seems to be feasible for PwP. Treatment adherence was 100%, 70% declared motivation to continue TC, and 96% intended to recommend TC to peers. Furthermore, PwP showed statistically significant improvements in 10-meter walking tests (T0: 7.5 (1.1-13.9), T1: 6.5 (0.1-12.9); p < .01; n = 16), 2-minute walking tests (T0: 149.5 (-111.0-410.0), T1: 177.0 (-140.7-494.7); p < .01; n = 19), Functional Gait Assessment (T0: 26.0 (-24.8-76.8), T1: 28.0 (2.6-53.4); p < .01; n = 15), and Nine-Hole-Peg tests (left: T0: 26.5 (24.3-28.7), T1: 24.1 (22.0-26.3); p < .01; n = 15; right: T0: 26.7 (24.1-29.2), T1: 23.3 (20.8-25.7); p < .01; n = 15).

CONCLUSION: The preliminary findings suggest that TC offers an effective and feasible training method that may positively affect PwP overall perceptions of physical and psychosocial health status. The methodological limitations and small sample size limit the study’s interpretability. More research is needed to definitely show the scientifically significant benefits of TC to PwP.

Spatiotemporal trends in burden of uterine cancer and its attribution to body mass index in 204 countries and territories from 1990 to 2019

Cancer Med. 2022 Feb 13. doi: 10.1002/cam4.4608. Online ahead of print.

ABSTRACT

BACKGROUND: Uterine cancer is one of the most common female cancers worldwide, with huge heterogeneity in morbidity and mortality. Although a high body-mass index (BMI) has been linked to uterine cancer, systematic reports about the influence of high BMI and its temporal trends are scarce.

METHODS: The annual morbidity, mortality, and disability-adjusted life years (DALYs) of uterine cancer in 204 countries or territories were retrieved from the GBD 2019 study. To reflect trends in disease burden, we also calculated the estimated annual percentage change (EAPC) based on the age-standardized rates of uterine cancer from 1990 to 2019.

RESULTS: The global incident cases of uterine cancer increased 2.3 times from 187,190 in 1990 to 435,040 in 2019. Although the age-standardized incidence rate (ASIR) of uterine cancer increased worldwide from 8.67/100,000 in 1990 to 9.99/100,000 in 2019, the age-standardized death rate (ASDR) and DALY rate decreased during the same period. High socio-demographic index (SDI) countries tended to have a higher ASIR than developing regions, and their increasing trend in ASIR was also more pronounced. The disease was rare before 40 years old, but its risk rose sharply among women aged 50-70. A high BMI was linked to more than one-third of deaths from uterine cancer in 2019.

CONCLUSIONS: The incidence in developed areas was significantly higher than in developing areas and also increased much more rapidly. Elderly females, especially those with a high BMI, have a higher risk of uterine cancer. Therefore, more health resources may be needed to curb the rising burden in specific populations.

Nursing students’ self-directed learning abilities and related factors at graduation: A multi-country cross-sectional study

Nurs Open. 2022 Feb 13. doi: 10.1002/nop2.1193. Online ahead of print.

ABSTRACT

AIM: To describe nursing students’ level of self-directed learning abilities and identify possible factors related to it at graduation in six European countries.

DESIGN: A cross-sectional comparative design across the countries.

METHODS: The study was conducted from February 2018 to September 2019. Nursing students (N = 4,135) from the Czech Republic, Finland, Italy, Portugal, Slovakia and Spain were invited to respond to the research instruments (the Self-Rating Scale of Self-Directed Learning and the Nurse Competence Scale) at graduation. The data were analysed using the chi-square test, Pearson correlation coefficient and the linear model.

RESULTS: The nursing students’ (N = 1,746) overall self-directed learning abilities were at high level in all countries. Statistically significant differences occurred between countries. Spanish nursing students reported the highest level of self-directed learning abilities while students from the Czech Republic reported the lowest. Higher level of self-directed learning abilities was related to several factors, particularly with the self-assessed level of competence and country.

Airflow for initial nonsurgical treatment of peri-implantitis: A systematic review and meta-analysis

Clin Implant Dent Relat Res. 2022 Feb 13. doi: 10.1111/cid.13072. Online ahead of print.

ABSTRACT

BACKGROUND: Nonsurgical treatment of peri-implantitis may help in reducing microbial load and inflammatory parameters. The potential clinical benefits of using different treatment approaches, in the initial nonsurgical treatment phase, particularly the airflow, are still not clear. The aim of this systematic review and meta-analyses was to evaluate the outcomes of nonsurgical treatment of peri-implantitis using airflow method in terms of changes in periodontal parameters, peri-implant marginal bone level, postoperative pain/discomfort, and patient satisfaction.

METHODS: Electronic databases were searched to identify randomized controlled trials (RCTs) that compared airflow with mechanical debridement using ultrasonic/curettes. The risk of bias was assessed using the Cochrane Collaboration’s Risk of Bias tool. Data were analyzed using a statistical software program.

RESULTS: A total of 316 studies were identified, of which, five RCTs with 288 dental implants in 174 participants were included. Overall meta-analysis showed more reduction in probing pocket depths at 1-3 months (mean difference [MD] -0.23; 95% confidence interval [CI] -0.50-0.05; p = 0.10) and 6 months (MD -0.04; 95% CI -0.34 to 0.27; p = 0.80) in favor of airflow, but the difference was not statistically significant. The use of airflow was associated with significant reduction in bleeding on probing and increase in peri-implant mucosal recession. The differences in plaque score, peri-implant marginal bone level changes, and patient reported outcomes between airflow and mechanical debridement were not statistically significant.

CONCLUSIONS: The short-term clinical and radiographic outcomes following nonsurgical treatment of peri-implantitis using airflow or mechanical debridement were comparable. The airflow has short-term positive effects on reducing bleeding on probing. Further evidence from RCTs are still required to substantiate the current findings.

Hemorrhagic dot score as a follow up marker in psoriasis on treatment: a prospective observational study

Dermatol Ther. 2022 Feb 14:e15379. doi: 10.1111/dth.15379. Online ahead of print.

ABSTRACT

CONTEXT: Psoriasis assessment tools in use presently lack reproducibility and are cumbersome to use. An easily reproducible, objective tool with ability to maintain visual records for follow up is hence desirable. We conducted a study with the aim to assess dermoscopic changes in psoriasis while on treatment by recording the number of hemorrhagic dots (Hemorrhagic Dot Score-HDS) in a representative plaque and comparing it to the PASI score.

SETTINGS AND DESIGN: A longitudinal prospective study was conducted between October 2018 to March 2020 in a dermatology centre of a tertiary hospital on cases of chronic plaque psoriasis on treatment over 6 months, assessed at baseline and thereafter monthly for six months.

METHODS: Hundred consenting patients of chronic plaque psoriasis were assessed, clinically, PASI and dermoscopically. HDS and other dermoscopic features were noted at every visit.

STATISTICAL ANALYSIS USED: ANOVA and F test of testing of equality of Variance; effect size in terms of Cohen were used to report the strength of an apparent relationship.

RESULTS AND INTERPRETATION: Percentage improvement in the mean PASI scores and HDS and percentage improvement of mean was found significant in each month on follow up. Systemic therapy as compared to topical therapy showed higher effect size of 6.1 and 1.7 respectively.

CONCLUSION: Hemorrhagic dot score can be used as an objective, definite assessment tool correlating with clinical severity of psoriasis with more accuracy which shows changes early following institution of therapy. This article is protected by copyright. All rights reserved.

Systematic review and meta-analysis: Associations between metabolic syndrome and colorectal neoplasia outcomes

Colorectal Dis. 2022 Feb 13. doi: 10.1111/codi.16092. Online ahead of print.

ABSTRACT

AIM: Metabolic syndrome (MetS) is a cluster of factors including obesity, hypertension, diabetes, hypercholesterolemia and hyperlipidaemia. It has been associated with an increased risk of colorectal neoplasia. This systematic review and meta-analysis assessed the association between MetS and: (i) recurrence of adenomas or occurrence of CRC in patients with prior adenomas; (ii) survival in patients with CRC.

METHOD: MEDLINE, Embase, Scopus and Web of Science were searched up to 22/11/2019. Two authors independently conducted title and abstract screening; full text of eligible studies was evaluated. Where ≥3 studies reported effect measures for a specific outcome, meta-analysis using random effects model was conducted. I2 was used to assess between-study heterogeneity. Quality appraisal was undertaken with the Newcastle-Ottawa Score.

RESULTS: The search identified 1764 articles, 55 underwent full text screening, resulting in a total of 15 eligible studies. Five studies reported on metachronous neoplasia, with differing outcomes precluded a meta-analysis. No consistent relationship between MetS and metachronous neoplasia was found. Ten studies reported on survival outcomes. MetS was associated with poorer CRC-specific survival (HR=1.8, 95%CI 1.04-3.12, I2 =92.7%, n=3). Progression-free survival was also worse but this did not reach statistical significance (HR=1.12, 95%CI 0.89-1.42, I2 =85.6%, n=3). There was no association with overall survival (HR=1.04, 95%CI 0.94-1.15, I2 =43.7%, n=7). Significant heterogeneity was present but subgroup analysis did not account for this.

CONCLUSION: MetS is associated with poorer CRC-specific survival, but evidence is inconsistent on metachronous neoplasia. Further research is warranted to better understand the impact of MetS on the adenoma-carcinoma pathway.
