ABSTRACT

This exploratory sub-study aimed to develop a framework to conceptualize boredom in stroke survivors during inpatient rehabilitation, establish the effect of an activity promotion intervention on boredom, and to investigate factors that are associated with boredom. A framework was developed and explored within a cluster non-randomised controlled trial. Self-reported boredom was measured in 160 stroke survivors 13 (±5) days after rehabilitation admission; 91 participants received usual-care (control) and 69 had access to a patient-driven model of activity promotion (intervention). Individuals with pre-existing dementia or unable to participate in standard rehabilitation were excluded. Hierarchical logistic regression analysis was used to identify demographic, health and activity measures associated with boredom. Results indicated 39% of participants were highly bored. There was no statistically significant difference in boredom levels between treatment groups (difference -11%, 95% CI -26% to 4%). The presence of depression (OR 6.17, 95% CI 2.57-14.79) and lower levels of socialization (OR 0.96, 95% CI 0.92-0.99) predicted high boredom levels. This comprehensive framework provides a foundation for understanding the many interacting factors associated with boredom. Results suggest managing depression and improving opportunities for socialization may support meaningful engagement in rehabilitation to optimize recovery following stroke.

ABSTRACT

BACKGROUND: A large number of nurse researchers do not adhere to ethical standards while performing the research. Moreover, there is far less data on knowledge of existing national ethical guidelines. This study was, therefore, done to assess awareness and adherence to current national ethical guidelines among nursing students and faculty members.

METHODS: A cross-sectional descriptive study was done among nursing faculty members and theses carried out by postgraduate nursing students between 2012 and 2017. Using the convenience sampling technique, seven states of North India were selected. In each of the selected seven states, one government and one private nursing college was selected. Thus, a sample of 14 nursing colleges was selected. Then, using simple random sampling, a total of 140 nursing faculty members and 280 postgraduate nursing theses were selected from all the chosen institutes to be part of the study. Data analysis was done using descriptive statistics.

ETHICAL CONSIDERATIONS: The study has been approved by the institutional ethical committee (ECR/737/Inst/UK/2018/RR-18). In addition, written permission from the head of each nursing institute was obtained before conducting the study. After participants read the Participation Information Sheet, they were asked for written informed consent before data collection. Confidentiality of the information and anonymity of the participants were maintained throughout the study.

RESULTS: The majority (81.8%) of the participants were females. It was found that compared to private nurses, government college nurses were more adhered to the research guidelines on research project approval (68.6% vs 22.1%), informed consent guidelines (74.3% vs 25%), providing patient information sheets (55.7% vs 10%), maintaining information confidentiality (82.9% vs 72.1%), maintaining anonymity (76.4% vs 22.9%) and obtaining custodian permission (97.8 vs 89.3%). It was also shown that nurses were more aware of the informed consent process domain (4.3 ± 0.3) followed by the general ethical principles domain (3.8 ± 0.8).

CONCLUSION: Government college nurses adhered more to the research guidelines as compared to those employed in private settings. Most of the faculty members were not part of any clinical trials and had no research ethics training at all. Therefore, it is needed to provide an instructional programme to raise awareness of the research ethical standards.

ABSTRACT

BACKGROUND: Primary human papillomavirus (HPV) screening is recommended for the detection of cervical intraepithelial neoplasia (CIN) in the general population; however, the triage for HPV-positive women remains a challenge. This study aimed to evaluate the age-specific effectiveness of primary HPV screening versus primary cytology screening for identifying optimal strategies for women of different ages.

METHODS: The dataset of the prevalence round screening was derived from the National Cervical Cancer Screening Program in China. Primary cervical screening protocols included cytology only, HPV testing with cytology triage, and HPV testing with HPV-16/18 genotyping plus cytology triage. The primary outcomes were age-specific detection rate, colposcopy referral rate and positive predictive value (PPV) for CIN2+. Multivariate Poisson regression was used to evaluate the relative effectiveness of HPV testing and cytology according to age groups. The I² statistic with a random-effect model was used to test the heterogeneity in relative effectiveness of HPV testing versus cytology between age groups.

RESULTS: This study included 1,160,981 women. HPV testing with HPV-16/18 genotyping plus cytology triage significantly increased the CIN2+ detection by 36% (rate ratio [RR]: 1.36, 95% confidential interval [CI] 1.21-1.54) for women aged 35-44 years and by 34% (RR: 1.34, 95% CI 1.20-1.51) for women aged 45-54 years compared with cytology only. HPV testing with cytology triage had similar CIN2+ detection rate compared with cytology only. The PPVs were substantially increased for both HPV testing groups. Among women aged 55-64 years old, HPV testing with HPV-16/18 genotyping plus cytology triage increased the colposcopy referral rate by 19% (RR 1.19, 95% CI 1.10-1.29) compared with cytology only, but did not increase the CIN2+ detection (1.09, 0.91-1.30). The effectiveness of HPV testing with cytology triage did not change in older women. The between-age-group heterogeneity in the effectiveness was statistically significant for HPV testing with HPV-16/18 genotyping plus cytology triage versus cytology only.

CONCLUSIONS: Our results suggested that the effectiveness of primary HPV screening with different triage strategies differed among age groups. HPV testing with HPV-16/18 genotyping plus cytology triage could be used for women aged 35-54 years to detect more lesions, and HPV testing with cytology triage could balance the CIN2+ detection and the number of colposcopies for women aged 55-64 years. Longitudinal data including both prevalence and incidence screening rounds are warranted to assess age-specific triage strategies.

ABSTRACT

AIMS: Although comprehensive cardiac rehabilitation (CCR) is recommended for patients with heart failure (HF), participants often show low adherence. The aim of this study was to evaluate the association of CCR completion and response with long-term clinical outcomes.

METHODS AND RESULTS: We screened 824 HF patients who participated in a 3 month CCR programme and underwent baseline assessment, including cardiopulmonary exercise testing (CPX). After excluding 52 participants who experienced all-cause death or HF hospitalization within 180 days, long-term outcomes were compared between those who attended 3 month follow-up assessment including CPX (completers) and those who did not (non-completers). We also compared the prognostic value of the changes in peak oxygen uptake (VO₂ ) vs. quadriceps muscle strength (QMS) during the 3 month CCR programme. Among the 772 study patients, there were no significant differences in baseline characteristics, including left ventricular ejection fraction, B-type natriuretic peptide levels, and peak VO₂ , between the completers (n = 561) and non-completers (n = 211), except for a higher age (63.2 ± 14.2 vs. 59.4 ± 16.2 years; P = 0.0015) and proportion of females (27% vs. 17%; P = 0.0030) among the completers. During a median follow-up of 55.4 months, the completers had lower rates of the composite of all-cause death or HF hospitalization (34.4% vs. 44.6%; P = 0.0015) and all-cause death (16.9% vs. 24.6%; P = 0.0037) than the non-completers. After adjustment for prognostic baseline characteristics, including age and sex, CCR completion was associated with 34% and 44% reductions in the composite outcome and all-cause death, respectively. Among the completers, peak VO₂ and QMS increased significantly (8.9 ± 15.8% and 10.5 ± 17.9%, respectively) over 3 months. Patients who had an increase in peak VO₂ ≥ 6.3% (median value) during the CCR programme had significantly lower rates of the composite outcome (27.0% vs. 33.8%; P = 0.048) and all-cause mortality (10.0% vs. 17.4%; P = 0.0069) than those who did not. No statistically significant difference was observed in the composite outcome (30.5% vs. 30.4%; P = 0.76) or all-cause mortality (13.0% vs. 14.4%; P = 0.39) between those with and without an increase in QMS ≥8.3% (median value).

CONCLUSIONS: In HF patients who participated in a 3 month CCR programme, its completion was associated with lower risks of subsequent HF hospitalization and death. Within the group of patients who completed the programme, the improvement in exercise capacity, but not in skeletal muscle strength, over the 3-month period was associated with better outcomes. These findings highlight the importance of the post-CCR follow-up assessment, including CPX, to identify a patient’s adherence and response to the CCR programme.

ABSTRACT

Accurate prediction of binding poses is crucial to structure-based drug design. We employ two powerful artificial intelligence (AI) approaches, data-mining and machine-learning, to design artificial neural network (ANN) based pose-scoring function. It is a simple machine-learning-based statistical function that employs frequent geometric and chemical patterns of interacting atoms at protein-ligand interfaces. The patterns are derived by mining interfaces of “native” protein-ligand complexes. Each interface is represented by a graph where nodes are atoms and edges connect protein-ligand interfacial atoms located within certain cutoff distance of each other. Applying frequent subgraph mining to these interfaces provides “native” frequent patterns of interacting atoms. Subsequently, given a pose for a protein-ligand complex of interest, the pose-scoring function (the information-processing unit or neuron) calculates the degree of matching between the interaction patterns present at the pose’s interface and the native frequent patterns. The pose-scoring function takes into account the frequency of occurrence of the matching native patterns, the size of the match, and the degree of geometrical similarity between pose-specific and matching native frequent patterns. This novel “multi-body interaction” pose-scoring function (MBI-Score) was validated using two databases, PDBbind and Astex-85, and it outperformed seven commonly used commercial scoring functions. MBI-Score is available at www.khashanlab.org/mbi-score.

ABSTRACT

BACKGROUND: HIV-related sarcopenia is an emerging health issue that often remains undiagnosed and can lead to reduced quality of life, independence, and premature death if untreated. This study investigated the effects of a 6 month combined training (resistance plus aerobic exercise) (CT) intervention on diagnostic measures of sarcopenia, including grip strength, appendicular lean mass index (ALMI), and gait speed.

METHODS: Forty participants were randomized into either a CT group (n = 20; age = 38.3 ± 4.9 years) or a control group (CON; n = 20; age = 37.9 ± 5.1 years). Participants in the CT group performed three supervised sessions per week for 6 months, consisting of weekly reverse linear periodized resistance training followed by 20 min aerobic training. Participants in the CON group were instructed to continue with their current lifestyle habits. Assessments were completed at baseline and after 6 months. Statistical analyses were performed using a two-way analysis of covariance (ANCOVA) adjusted for sex and preintervention values. Primary outcomes included grip strength, ALMI, and gait speed. Secondary outcomes were changes in levels of pro-inflammatory cytokines (IL-6 and TNF-α), IGF-1, and myostatin. Associations were explored between changes in inflammatory markers (IL-6 and TNF-α), gait speed, and ALMI with grip strength.

RESULTS: A significant increase in ALMI was found for CT compared with CON (0.29 ± 0.13 kg/m² vs. -0.11 ± 0.14 kg/m² , respectively; P < 0.001). Significant improvements in grip strength (7.86 ± 8.50 kg for CT vs. -1.58 ± 2.47 kg for CON) and gait speed (0.16 ± 0.07 m/s² for CT vs. -0.06 ± 0.52 m/s² for CON; both P < 0.001) were also observed in CT compared with CON. Reduction in inflammatory biomarkers was found in CT compared with CON (IL-6; TNF-α, both P < 0.001). An increase in IGF-1 (74.36 ± 56.64 pg/mm³ for CT vs. 7.19 ± 99 pg/mm³ for CON; P < 0.001) and a decrease in myostatin (-158.90 ± 62.03 pg/mm³ for CT vs. -43.33 ± 146.60 pg/mm³ for CON; P < 0.001) was found following CT compared with the CON group. Change in grip strength was correlated with changes in IL-6 (r = -0.65, P < 0.001), TNF-α (r = -0.63, P < 0.001), gait speed (r = 0.63, P < 0.001), and ALMI (r = 0.54, P = 0.001), but not IGF-1 and myostatin. No adverse events were recorded, and compliance with the CT exercise sessions was high (>85%).

CONCLUSIONS: Combined training appears to be an effective means to counteract sarcopenia and improve various inflammatory markers and growth hormones in people living with HIV.

ABSTRACT

Recent theories propose that domain-general deficits in prediction (i.e., the ability to anticipate upcoming information) underlie the behavioral characteristics associated with autism spectrum disorder (ASD). If these theories are correct, autistic children might be expected to demonstrate difficulties on linguistic tasks that rely on predictive processing. Previous research has largely focused on older autistic children and adolescents with average language and cognition. The present study used an eye-gaze task to evaluate predictive language processing among 3- to 4-year-old autistic children (n = 34) and 1.5- to 3-year-old, language-matched neurotypical (NT) children (n = 34). Children viewed images (e.g., a cake and a ball) and heard sentences with informative verbs (e.g., Eat the cake) or neutral verbs (e.g., Find the cake). Analyses of children’s looking behaviors indicated that young autistic children, like their language-matched NT peers, engaged in predictive language processing. Regression results revealed a significant effect of diagnostic group, when statistically controlling for age differences. The NT group displayed larger difference scores between the informative and neutral verb conditions (in looks to target nouns) compared to the ASD group. Receptive language measures were predictive of looking behavior across time for both groups, such that children with stronger language skills were more efficient in making use of informative verbs to process upcoming information. Taken together, these results suggest that young autistic children can engage in predictive processing though further research is warranted to explore the developmental trajectory relative to NT development.

ABSTRACT

Approved, straightforward, fast and delicate spectrofluorimetric strategy has been developed for the estimation of tepotinib (TEPO), sotorasib (SOTO) and darolutamide (DARO) as a new antineoplastic drugs. Spectrofluorimetric strategy was based on quantitative fluorescence quenching of MER at 538 nm after being excited at 350 nm by the addition of cited drugs in presence of acetate buffer (pH 3.5). The degree of fluorescence quenching is directly proportional to the concentrations of the cited drugs within the concentration range of 0.5-10.0, 0.2-10 and 0.4-10.0 μg mL^-1 for TEPO, SOTO and DARO, respectively. Mean ± S.D. were calculated for the studied drugs as follows; 99.9±0.87, 99.72±1.08 and 100.21±1.44, for TEPO, SOTO and DARO, respectively. LOD values were 0.16, 0.05 and 0.11 μg mL^-1 while LOQ values were 0.5, 0.15 and 0.36 μg mL^-1 for TEPO, SOTO and DARO, respectively. Statistical comparison of comes about with those gotten by detailed strategies given great understanding and uncovered that there were no noteworthy contrasts in exactness and exactness between strategies. The proposed strategy was connected effectively to analyze measurement shapes containing the examined drugs. Moreover, the recommended fluorimetric strategy was connected for examination of TEPO, SOTO and DARO in human plasma and urine test.

ABSTRACT

BACKGROUND: Cancer-related cachexia is a major cause of treatment resistance and poor prognosis, which is characterized by anorexia and skeletal muscle depletion. To date, there have been no reports on the relationship between IL-35 and cancer-related cachexia in patients with stage IV non-small cell lung cancer.

METHODS: Serum IL-35 levels in 86 patients with stage IV NSCLC were measured and statistically analyzed based on patients’ clinicopathological parameters. Serum albumin levels, C-reactive protein, and skeletal muscle index (SMI) of the patients were also determined. In vivo studies using a mouse model were also conducted by subcutaneously injecting immunodeficiency (SCID) mice with overexpressing IL-35 cell lines and determining their daily food intake, bodyweight and muscle atrophy. Cachexia indicators were measured again after administering the mice with an anti-IL35 neutralizing antibody.

RESULTS: Patients with stage IV NSCLC had significantly higher serum IL-35 levels than the healthy controls. Similarly, circulating IL-35 levels were significantly higher in patients with cachexia than those without. The SMI values of patients with high serum IL-35 levels were significantly lower than those with low serum IL-35 levels. Mice subcutaneously injected with LLC PLV-IL-35 cell lines exhibited anorexia, weight loss, and muscle atrophy. Moreover, these symptoms were significantly reduced after administering the mice with an anti-IL35 neutralizing antibody.

CONCLUSIONS: This study reveals that high serum IL-35 expression is associated with non-small cell lung cancer cachexia and skeletal muscle atrophy. These findings highlight its potential as a biomarker and therapeutic target for controlling cachexia of advanced lung cancer.

ABSTRACT

BACKGROUND: Histopathologic evaluation after surgery is the gold standard to evaluate treatment response to neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer (LARC). However, it cannot be used to guide organ-preserving strategies due to poor timeliness.

PURPOSE: To develop and validate a multiscale model incorporating radiomics and pathomics features for predicting pathological good response (pGR) of down-staging to stage ypT0-1N0 after nCRT.

STUDY TYPE: Retrospective.

POPULATION: A total of 153 patients (median age, 55 years; 109 men; 107 training group; 46 validation group) with clinicopathologically confirmed LARC.

FIELD STRENGTH/SEQUENCE: A 3.0-T; fast spin echo T₂ -weighted and single-shot EPI diffusion-weighted images.

ASSESSMENT: The differences in clinicoradiological variables between pGR and non-pGR groups were assessed. Pretreatment and posttreatment radiomics signatures, and pathomics signature were constructed. A multiscale pGR prediction model was established. The predictive performance of the model was evaluated and compared to that of the clinicoradiological model.

STATISTICAL TESTS: The χ² test, Fisher’s exact test, t-test, the minimum redundancy maximum relevance algorithm, the least absolute shrinkage and selection operator logistic regression algorithm, regression analysis, receiver operating characteristic curve (ROC) analysis, Delong method. P < 0.05 indicated a significant difference.

RESULTS: Pretreatment radiomics signature (odds ratio [OR] = 2.53; 95% CI: 1.58-4.66), posttreatment radiomics signature (OR = 9.59; 95% CI: 3.04-41.46), and pathomics signature (OR = 3.14; 95% CI: 1.40-8.31) were independent factors for predicting pGR. The multiscale model presented good predictive performance with areas under the curve (AUC) of 0.93 (95% CI: 0.88-0.98) and 0.90 (95% CI: 0.78-1.00) in the training and validation groups, those were significantly higher than that of the clinicoradiological model with AUCs of 0.69 (95% CI: 0.55-0.82) and 0.68 (95% CI: 0.46-0.91) in both groups.

DATA CONCLUSION: A model incorporating radiomics and pathomics features effectively predicted pGR after nCRT in patients with LARC.
