Crouch gait pattern is a common gait pattern in children with diplegic cerebral palsy with excessive knee flexion throughout stance phase. Few studies have grouped this pattern of gait and usually have examined only the features of gait in the sagittal plane and mostly lower extremities without considering pelvis and trunk behavior. Studies usually categorize the gait pattern according to important variables from the researcher's point of view. Sparse K-means is high dimensional clustering methods that perform clustering and variable selection simultaneously even with low sample size and large number of variables. Our aim was to define existing clusters of crouch gait pattern in children with spastic diplegic cerebral palsy.

Cluster analysis was applied on the lower extremity, pelvis and trunk gait kinematics data of 64 limbs of children with crouch gait pattern and 64 limbs of typically developing children. Eighty-nine kinematic variables were used as input variables for clustering.

Four clusters of crouch gait pattern were defined. Sparse K-means identified influential variables and identified the knee and hip flexion as a major factor in clustering. Kinematic of the trunk, pelvis and ankle was determined in each cluster. Trunk and pelvis kinematic features were strongly correlated with the knee and hip joint flexion severity.

Obtained clusters were confirmed observationally. With increasing knee flexion, the kinematic of the trunk and pelvis were further away from the patterns of typically developing individuals. The clusters ranking appear to be reasonable based on the crouch severity.

The interrelation between DNA repair deficiency and the increased effect of DNA targeting agents highlights the double-strand break (DSB) repair, which comprises the homologous recombination (HR) and non-homologous end joining (NHEJ) pathways. The DNA targeting agents are classified into two major groups non-covalent DNA binding agents and covalent DNA-reactive agents. Although these agents have well-known limitations, such as resistance and secondary carcinogenesis risk, they are extremely important in today's real-life cancer therapy in combination with targeted therapy and immunotherapy. Indeed, DNA targeting drugs are promising therapeutics with a precise application through the background of cancer-specific DNA repair failure. In the current review, the mechanisms of action of diversified DNA-targeting agents, as well as the modulation of DNA repair pathways to increase the DNA-damaging drugs efficacy are presented. Finally, DNA-targeting-based therapies are discussed considering risks, resistance and its uses in the medicine precision era.
Although previous studies showed that frail older adults are more susceptible to develop cardiovascular diseases, the underlying effect of frailty on heart rate dynamics is still unclear. The goal of the current study was to measure heart rate changes due to normal speed and rapid walking among non-frail and pre-frail/frail older adults, and to implement heart rate dynamic measures to identify frailty status.

Eighty-eight older adults (≥65 years) were recruited and stratified into frailty groups based on the five-component Fried frailty phenotype. While performing gait tests, heart rate was recorded using a wearable ECG and accelerometer sensors. Groups consisted of 27 non-frail (age=78.70±7.32) and 61 pre-frail/frail individuals (age=81.00±8.14). The parameters of interest included baseline heart rate measures (mean heart rate and heart rate variability), and heart rate dynamics due to walking (percentage change in heart rate and required time to reach the maximum heart rate).

Respectively for normal and rapid walking conditions, pre-frail/frail participants had 46% and 44% less increase in heart rate, and 49% and 27% slower occurrence of heart rate peak, when compared to non-frail older adults (p<0.04, effect size=0.71±0.12). Measures of heart rate dynamics showed stronger associations with frailty status compared to baseline resting-state measures (sensitivity=0.75 and specificity=0.65 using heart rate dynamics measures, compared to sensitivity=0.64 and specificity=0.62 using baseline parameters).

These findings suggest that measures of heart rate dynamics in response to daily activities may provide meaningful markers for frailty screening.

Military deployments to austere environments since November 9, 2001 may put "deployers" at risk for respiratory disease. Sensitive, noninvasive tools for detecting large and small airways injury are needed to identify early disease and help inform management for this at-risk population.

We examined multiple breath washout (MBW) as a tool for identifying deployment-related airways disease and assessed host and exposure risk factors compared to healthy controls.

Between March 2015 and March 2020, 103 healthy controls and 71 symptomatic deployers with asthma and/or distal lung disease completed a questionnaire, spirometry and MBW testing. SAS v. 9.4 was used to compare MBW parameters between deployers and controls via univariate analyses and adjusted for demographic factors using multiple linear regression.

Deployers were significantly more likely than controls to have an abnormal lung clearance index (LCI) score indicating global ventilation inhomogeneity. Adjusting for sex, smoking status, smoking pack-years and body mass index, LCI scores were significantly more abnormal among those with deployment-related asthma and distal lung disease compared to controls. The unadjusted variable Sacin (a marker of ventilation inhomogeneity in the acinar airways) was higher and thus more abnormal in those with both proximal and distal airways disease. Deployers who reported more frequent exposure to explosive blasts had significantly higher LCI scores.

This study demonstrates the utility of MBW in evaluating exposure-related airways disease in symptomatic military personnel following deployment to austere environments, and is the first to link exposure to explosive blasts to measurable small airways injury.

Different subtypes of nicotinic acetylcholine receptors (nAChRs) are involved in modulation of PMN activities. Earlier we determined expression of α2-7, α9, β3, β4 subunits and regulatory role of α7 and α3β2 nAChR subtypes in functions of inflammatory PMNs. selleck chemicals Other authors detected mRNA of α9 subunit in bone marrow neutrophils (BM-PMNs). Murine BM-PMNs coming out from the bone marrow, where they develop, to blood were characterized as mature. There was no data for α10 and for the presence of functionally active α9α10 nAChRs in BM-PMNs. Here we detected for the first time mRNA expression of the α10 nAChR subunit in BM-PMNs and confirmed the expression of mRNA for α9 nAChR. With the help of α-conotoxins RgIA and Vc1.1, highly selective antagonists of α9α10 nAChRs, we have revealed participation of α9 and/or α9α10 nAChRs in regulation of cytosolic Ca2+ concentration, cell adhesion, and in generation of reactive oxygen species (ROS). Nicotine, choline, RgIA, and Vc1.1 induced Ca2+ transients in BM-PMNs, enhanced cell adhesiveness and decreased production of ROS indicating involvement of α9, possibly co-assembled with α10, nAChRs in the BM-PMN activity for recruitment and cytotoxicity.
Mothers of infants with congenital heart disease are at risk for depression.

This study explored the influence on maternal depressive symptoms of several known factors for mothers in the pediatric cardiac intensive care unit, including perceived stressors, attachment, and anxiety.

This study was a secondary analysis of 30 mothers of infants awaiting cardiac surgery. Linear regressions were calculated to determine the relationships between perceived stressors, maternal attachment, anxiety, and maternal depressive symptoms.

Nearly half of mothers reported depressive symptoms above the measure cut-off score, indicating they were at risk for likely clinical depression. Subscales of perceived stress explained 61.7% of the variance in depressive symptoms (F=11.815, p<0.0001) with parental role alteration subscale as the strongest predictor (standardized beta=0.694, p=0.03).

Findings underscore the importance of mental health screening and instituting nursing practices to enhance parental role for mothers of infants awaiting cardiac surgery.

Takotsubo cardiomyopathy (TCM) patients may benefit from cardiac rehabilitation (CR).

The purpose to this study is to examine utilization of CR in TCM.

We conducted a review of hospitalized TCM patients at Baystate Medical Center between 2010 and 2017. link2 We evaluated rates of referral, enrollment, adherence, and changes in exercise capacity. Predictors of CR utilization were analyzed using t-test, chi-square/odds ratio and multivariable hierarchical modeling when appropriate.

Over 8 years, 35% of 590 patients with TCM were evaluated by phase I (inpatient) and 13.6% enrolled in phase II (outpatient) CR. Inpatient CR evaluation (OR 21, 95% CI 7-64) and cardiac catheterization (OR 5.7, 95% CI 1.9-17) were strong predictors of outpatient CR participation. Patients enrolling in CR attended 15±14 sessions and increased their exercise capacity by 1.2 METs (95% CI 0.9-1.5).

CR is inconsistently used in TCM, despite the potential physiologic benefits of exercise in TCM.

There is paucity of data on cardiac rehabilitation (CR) enrollment and outcomes in women with heart failure (HF).

In this retrospective analysis, we compared enrollment, adherence and outcomes between women with HF versus coronary artery disease (CAD)-related indications referred to a university-affiliated CR program from June 2014-July 2018. A multivariate regression analysis was performed to adjust for imbalanced variables at baseline and baseline value of each outcome to compare change in outcomes between HF and CAD groups RESULTS A total of 538 women (HF=63vs CAD=475) were included in the study. At baseline, women with HF were younger, had lower attendance to CR intake and worse perceived health, higher AACVPR risk category and lower exercise capacity but had similar enrollment, weight and dieatry habits when compared to women with CAD. link3 Adjusted analyses showed that almost all cardiac rehabilitation outcomes except for positive affect (anxiety, depression symptoms, negative affect, dietary habits, perceived physical and mental health summary scores, exercise duration and capacity) improved significantly from baseline and in a similar fashion in both groups.
