Published: January 2024

ObjectiveNeuropathic pain (NP) may influence disease activity assessment in patients with psoriatic arthritis, this relationship being traditionally based on the presence of concomitant fibromyalgia. We analyzed the influence of other comorbidities on NP and the relationship between pain and various clinical parameters.MethodsA cross-sectional study was conducted in patients diagnosed with psoriatic arthritis, excluding patients with a previous diagnosis of fibromyalgia, depression, anxiety, diabetes and/or dyslipidemia under treatment. NP was identified using the painDETECT questionnaire (score &gt; 18). Obesity and related clinical parameters, anxious and depressive symptoms, sleep quality and fatigue were assessed as comorbidities. Disease activity was measured using the clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) in peripheral involvement, the ASDAS-PCR in axial involvement, functioning and disease impact were measured using the Health Assessment Questionnaire-Disability Index and 12-item Psoriatic Arthritis Impact of Disease questionnaire, respectively.ResultsOverall, 246 patients were included (136 men; 55%). The mean age was 53.4 ± 11.0 years. Forty-two patients had NP (17.1%). Patients with NP had higher leptin levels (OR: 1.03, 95% CI: 1.007–1.056; p &lt; 0.01) and poor sleep quality (OR: 1.20, 95% CI: 1.09–1.297; p &lt; 0.001). Patients with NP also had greater fatigue NRS (6.2 ± 2.2 vs. 2.4 ± 0.19, p &lt; 0.001). Patients with NP had higher cDAPSA score (17.3 ± 5.4 vs. 8.9 ± 6.5, p &lt; 0.001), poorer functioning (1.1 ± 0.5 vs. 0.4 ± 0.5, p &lt; 0.001) and greater disease impact (6.1 ± 1.7 vs. 2.6 ± 1.9, p &lt; 0.001).ConclusionNP was correlated with sleep quality and serum leptin and may be associated with worse disease activity, functioning and disease impact.

Published: January 2024

BackgroundDietary fat consumption, involved in the pathogenesis of insulin resistance and impaired glucose metabolism, is linked with decline in cognitive functions, dementia, and development of Parkinson’s disease and Alzheimer’s disease. Mature IL-1β, requiring the activation of the P2X7 receptor (P2X7R)-inflammasome complex, is an important mediator of neuroinflammation. The aim of the study was to test whether P2X7R activation might interfere with systemic and cerebral metabolic homeostasis.MethodsWe treated WT and P2X7R KO mice with a high-fat diet (HFD) for 16 weeks, evaluating the effects on the Substantia Nigra and Hippocampus, target areas of damage in several forms of cognitive impairment.ResultsHFD-treated WT and P2X7R KO mice showed a different brain mRNA profile of Insulin and Igf-1, with these genes and relative receptors, more expressed in KO mice. Unlike P2X7R KO mice, WT mice treated with HFD displayed a diameter reduction in dopaminergic neurons in the Substantia Nigra, accompanied by an increased IBA1 expression in this area; they also showed poor performances during Y-Maze and Morris Water Maze, tasks involving Hippocampus activity. Conversely, Parkin, whose reduction might promote neuronal cell death, was increased in the brain of P2X7R KO animals.ConclusionWe report for the first time that HFD induces damage in dopaminergic neurons of the Substantia Nigra and a Hippocampus-related worse cognitive performance, both attenuated in the absence of P2X7R. The involved mechanisms might differ in the two brain areas, with a predominant role of inflammation in the Substantia Nigra and a metabolic derangement in the Hippocampus.

BackgroundPatients undergoing hemodialysis (HD) frequently experience the chronic kidney disease-associated pruritus (CKD-aP).ObjectiveThe aim of this study was to investigate the effectiveness of omega-3 supplementation in the management of CKD-aP in patients undergoing hemodialysis.MethodsIn this triple blind, randomized clinical trial, the effect of the omega-3 supplement on uremic CKD-aP was assessed in 112 chronic hemodialysis patients at Caspian Hemodialysis Center in Rasht, Iran. Patients were randomly divided into the intervention group receiving omega-3 supplements (3 g/day) and the control group receiving placebo containing MCT oil for 2 months.ResultsOmega-3 supplementation had no effect on CKD-aP. The results did not change after adjusting for age and sex, additional adjustments for weight, height, physical activity, smoking, and alcohol use, additional adjustments for underlying diseases and weight, height, physical activity, smoking, and drinking alcohol, and further adjustments for underlying diseases and biochemical indices.DiscussionOmega-3 supplementation for 2 months had no effect on CKD-aP in patients with CKD. Further studies with longer duration are warranted.Clinical Trial Registrationhttps://www.irct.ir/trial/66638, IRCT20151226025699N6

ObjectiveThe importance of cardio-hemato-oncology programs is increasing. The main aim of the study was to identify all coexisting cardiovascular disorders in patients with new hematological malignancies referred for echocardiography during baseline evaluation before anticancer therapy.Material and methodsThe study was based on 900 echocardiographic examinations performed within 12 months at the Institute of Hematology and Transfusion Medicine in Poland: 669 tests (74.3%) were dedicated to hemato-oncology patients at the different stages of cancer therapy, however almost a third of the tests (277, 30.8%) were part of a baseline evaluation before starting first line anticancer therapy due to newly diagnosed hematological malignancies.ResultsThe group of 277 patients with new hematological malignancies (138 women, 49.82%) with a median age of 66 years (interquartile range: 53-72 years) was included in the main analyses. The three most frequent new histopathological diagnoses were: non-Hodgkin lymphoma (63 cases; 22.74%), acute myeloid leukaemia (47 cases; 16.97%), and multiple myeloma (45 cases; 16.25%). The three most common clinical cardiology disorders were arterial hypertension (in 133 patients, 48.01%), arrhythmias (48 patients, 17.33%), and heart failure (39 patients, 14.08%). Among 48 patients with arrhythmias there were 22 cases with atrial fibrillation. The most frequently detected echocardiographic abnormality was Left Atrial Volume Index &gt;34 ml/m2 which was present in 108 of 277 patients (38.99%) and associated with a significantly greater chance of concomitant diagnosis of arrhythmias (OR=1.98; p=0.048) especially atrial fibrillation (OR=3.39; p=0.025). The second most common echocardiographic finding was diastolic dysfunction 2nd or 3rd degree revealed in 43 patients (15.52%) and associated with a greater chance of simultaneous diagnosis of heart failure (OR=8.32; p&lt;0.0001) or arrhythmias (OR=4.44; p&lt;0.0001) including atrial fibrillation (OR=5.40; p=0.0003).ConclusionsIn patients with newly diagnosed hematological malignancies left ventricular diastolic dysfunction is a common abnormality in echocardiography and may determine diagnoses of heart failure or arrhythmias.

ObjectiveTo assess the utility of predictive models using ultrasound radiomic features to predict cervical lymph node metastasis (CLNM) in solitary papillary thyroid carcinoma (PTC) patients.MethodsA total of 570 PTC patients were included (456 patients in the training set and 114 in the testing set). Pyradiomics was employed to extract radiomic features from preoperative ultrasound images. After dimensionality reduction and meticulous selection, we developed radiomics models using various machine learning algorithms. Univariate and multivariate logistic regressions were conducted to identify independent risk factors for CLNM. We established clinical models using these risk factors. Finally, we integrated radiomic and clinical models to create a combined nomogram. We plotted ROC curves to assess diagnostic performance and used calibration curves to evaluate alignment between predicted and observed probabilities.ResultsA total of 1561 radiomics features were extracted from preoperative ultrasound images. After dimensionality reduction and feature selection, 16 radiomics features were identified. Among radiomics models, the logistic regression (LR) model exhibited higher predictive efficiency. Univariate and multivariate logistic regression results revealed that patient age, tumor size, gender, suspicious cervical lymph node metastasis, and capsule contact were independent predictors of CLNM (all P &lt; 0.05). By constructing a clinical model, the LR model demonstrated favorable diagnostic performance. The combined model showed superior diagnostic efficacy, with an AUC of 0.758 (95% CI: 0.712-0.803) in the training set and 0.759 (95% CI: 0.669-0.849) in the testing set. In the training dataset, the AUC value of the nomogram was higher than that of the clinical and radiomics models (P = 0.027 and 0.002, respectively). In the testing dataset, the AUC value of the nomogram model was also greater than that of the radiomics models (P = 0.012). However, there was no significant statistical difference between the nomogram and the clinical model (P = 0.928). The calibration curve indicated a good fit of the combined model.ConclusionUltrasound radiomics technology offers a quantitative and objective method for predicting CLNM in PTC patients. Nonetheless, the clinical indicators persists as irreplaceable.

Published: January 2024

PurposePersonal informatics devices are being used to measure engagement in health behaviors in adults with chronic pain and may be appropriate for adolescent use. The aim of this study was to evaluate the utilization of a wearable activity tracking device to measure physical activity and sleep among adolescents attending a three-week, intensive interdisciplinary pain treatment (IIPT) program. We also assessed changes in physical activity and sleep from baseline to the treatment phase.MethodsParticipants (57.1% female, average age 15.88, SD = 1.27) wore an activity tracking device three weeks prior to starting and during the treatment program.ResultsOf 129 participants contacted, 47 (36.4%) agreed to participate. However, only 30 (64%) complied with the instructions for using the device prior to programming and during program participation. Preliminary analyses comparing averages from 3-weeks pre-treatment to 3-weeks during treatment indicated increases in daily overall activity minutes, daily step counts, and minutes of moderate to vigorous physical activity (by 353%), as well as a corresponding decrease in sedentary minutes. There was more missing data for sleep than anticipated.ConclusionsWearable activity tracking devices can be successfully used to measure adolescent physical activity in-person, with more difficulty obtaining this information remotely. Adolescents with chronic pain experience improvements in objective measurements of physical activity over the course of a 3-week IIPT program. Future studies may want to spend more time working with pediatric patients on their understanding of how to use trackers for sleep and physical activity.

Background: Schizophrenia is a serious psychiatric disorder that significantly affects the quality of life of patients. The objective of this study is to discover a novel antipsychotic candidate with highly antagonistic activity against both serotonin and dopamine receptors, demonstrating robust efficacy in animal models of positive, negative, and cognitive symptoms of schizophrenia.Methods: In the present study, we examined the activity of antipsychotic drug (NH300094) on 5-HT2A, 5-HT2C, 5-HT1A, 5-HT1B, 5-HT7, H1, M1, Alpha1A, D2L, D2S, Alpha2A, D3 receptor functional assay in vitro. In addition, multiple animal models, including dizocilpine (MK-801) induced hyper-locomotion; APO induced climbing; Conditioned Avoidance Response (CAR); DOI-Induced Head Twitch; Forced swimming test; Scopolamine induced cognitive impairment model, were used to verify the antipsychotic activity of NH300094 in preclinical.Results:In vitro functional assays have indicated that NH300094 is a potent antagonist of 5-HT receptors and dopamine receptors, with higher relative antagonistic activity against 5-HT2A receptor (5-HT2A IC50 = 0.47 nM) than dopamine receptors (D2L IC50 = 1.04 nM; D2S IC50 = 11.71 nM; D3 IC50 = 31.55 nM). Preclinical in vivo pharmacological study results showed that NH300094 was effective in multiple models, which is more extensive than the clinic drug Risperidone. Furthermore, the safety window for extrapyramidal side effects of NH300094 is significantly wider than that of Risperidone (For NH300094, mice catalepsy model ED50/ Mice MK-801 model ED50 = 104.6-fold; for Risperidone, mice catalepsy model ED50/ Mice MK-801 model ED50 = 12.9-fold), which suggests a potentially better clinical safety profile for NH300094.Conclusion: NH300094 is a novel potent serotonin and dopamine receptors modulator, which has good safety profile and therapeutic potential for the treatment of schizophrenia with cognition disorders.
Calculation of a conversion factor for estimating the glycolytic contribution in exercise from post-exercise blood lactate concentration
Authors: Hill David W. , Mihalek John Michael 
Published: January 2024

Purpose: Often, the glycolytic contribution in a bout of heavy or severe intensity exercise is estimated by multiplying the increase in blood lactate concentration above resting levels that is engendered by the exercise (in mM) by 3.3 (or 3) mL·kg−1 per mM. Our purpose was to verify the value of this conversion factor, using methods that were completely different from those of the original studies.Methods: Six women (mean ± SD), age, 23 ± 1 year; VO2max, 46 ± 4 mL·kg−1·min−1) and three men (23 ± 0 years; 54 ± 8 mL·kg−1·min−1) completed 6 min of heavy intensity exercise in conditions of normoxia and hypoxia (FIO2, ∼12%). VO2 was measured throughout the exercise and 7 min of recovery. The increase in glycolytic contribution was estimated as the reduction in aerobic contribution in hypoxia, after correction for the effects of hypoxia on the oxygen demand and on the contribution from phosphocreatine. The peak post-exercise blood lactate concentration was measured in fingerstick blood samples.Results: The ratio between the increase in estimated glycolytic contribution (in mL·kg–1) in hypoxia and the increase in peak blood lactate concentration (in mM) yielded an oxygen equivalent of 3.4 ± 0.4 mL·kg–1 per mM (range, 2.6 mL·kg−1 per mM to 4.0 mL·kg−1 per mM) for cycle ergometer exercise.Conclusion: These results generally support the use of a common conversion factor to calculate the glycolytic contribution from post-exercise blood lactate concentrations. However, there is some inter-individual variability in the conversion factor.

Introduction: The aims of this study were to: a) investigate salivary immunoglobulin A (s-IgA) and cortisol (s-Cort) responses to nine competitive fixtures in starting and non- starting soccer players; and b) compare s-IgA and s-Cort responses of starters and non-starters considering match outcome.Methods: Saliva from 19 male outfield players from an elite soccer team (mean ± SD, age 26 ± 4 years; weight 80.5 ± 8.1 kg; height 1.83 ± 0.07 m; body-fat 10.8% ± 0.7%) was collected. Saliva samples were taken on the day before each match (MD-1), 60-min before kick-off (MDpre), 30-min post-match (MDpost), and 72-h post-match (MD+3). There were five wins, one draw and three losses.Results: The mean s-IgA value was found to be significantly lower at MD+3 compared to MDpre and MDpost. s-Cort was significantly higher at MDpost compared to MD-1 and MDpre. When compared to MDpre, a statistically significant decrease in s-Cort was observed at MD+3 compared to MDpost. Starters displayed higher s-Cort values across the nine matches. There was a significant group-by-time interaction for s-Cort. There was a significant increase in s-Cort levels at MDpost compared to MD-1 and from MDpre to MDpost in starting players. At MDpost, starters had significantly higher s-Cort values. s-IgA values of starting and non- starting players following successful and unsuccessful matches did not reveal a significant difference. However, similar analysis of s-Cort in successful matches showed a significant difference between starters and non-starters. s-IgA values at MD-1, MDpre, MDpost and MD+3 in starters and non-starters following successful and unsuccessful matches revealed significant differences at MDpre and MDpost in starters, respectively. Furthermore, s-Cort values at MD-1, MDpre, MDpost and MD+3 in starters and non-starters in successful and unsuccessful matches revealed significant differences at MD+3 in starting players.Discussion: The present study suggests that in elite level soccer players, both starting status and match outcome influence s-IgA and s-Cort responses, particularly starters. Specifically, s-IgA was lower for starters before and after the match following successful outcomes. Moreover, higher s-Cort values were found before the match while lower values occurred after the match for starters in successful matches.

IntroductionAlfalfa (Medicago sativa L.) is the favored premium feed ingredient in animal husbandry production which is in serious jeopardy due to soil moisture shortages. It is largely unknown how different root types of alfalfa respond to arid-induced stress in terms of metabolites and phytohormones.MethodsTherefore, rhizomatous rooted M. sativa ‘Qingshui’ (or QS), tap-rooted M. sativa ‘Longdong’ (or LD), and creeping rooted M. varia ‘Gannong No. 4’ (or GN) were investigated to identify metabolites and phytohormones responses to drought conditions.ResultsWe found 164, 270, and 68 significantly upregulated differential metabolites were categorized into 35, 38, and 34 metabolic pathways in QS, LD, and GN within aridity stress, respectively. Amino acids, organic acids, sugars, and alkaloids were the four categories of primary differential metabolites detected, which include 6-gingerol, salicylic acid (SA), indole-3-acetic acid (IAA), gibberellin A4 (GA4), abscisic acid (ABA), trans-cinnamic acid, sucrose, L-phenylalanine, L-tyrosine, succinic acid, and nicotinic acid and so on, turns out these metabolites are essential for the resistance of three root-type alfalfa to aridity coercing.DiscussionThe plant hormone signal transduction (PST) pathway was dramatically enriched after drought stress. IAA and ABA were significantly accumulated in the metabolites, indicating that they play vital roles in the response of three root types of alfalfa to water stress, and QS and LD exhibit stronger tolerance than GN under drought stress.
Socially connected while apart: the use of technology to increase social connection between nursing home residents and their relatives
Authors: Akhtar Sehrish Andleeb 
Published: January 2024

IntroductionThis study examines whether the use of a communication technology can enhance social connectedness among nursing home residents in Norway. The concept of social connectedness suggest that positive and significant interpersonal relationships can help reduce the risk of loneliness and social isolation among older adults and can be beneficial for both their health and overall well-being. In recent years, technology has been increasingly utilized as a method to overcome physical distances and to keep families connected. Although the use of digital solutions among older people has increased in recent years, few studies have addressed the use and impact of such technologies within a nursing home context.MethodsA total of 225 residents participated in the study, making it one of the few quantitative studies that examine the use of communication technologies in nursing homes at such a large scale. The study combines two sources of data: (1) survey data collected over a 14-month period, in three different waves, at all public nursing homes in Oslo municipality and (2) a highly detailed weekly datastream from each Komp-device, which provides an objective measure of the frequency of contact between the residents and their families. The two sources of data were combined and analyzed using multiple regression analysis.ResultsThe regression analysis revealed a positive and significant relationship between Komp use and increased social satisfaction among the residents. The results indicate that Komp is a feasible communication tool to help nursing home residents maintain relations with their families.DiscussionThe positive response to Komp among the residents suggests that when designed with the user’s needs in mind, technology can indeed facilitate meaningful social interactions, even for those with limited technological experience. Such interventions can thus be crucial in bridging the gap between older residents and the outside world, effectively addressing their unique challenges of social isolation and disconnection from the broader community.
