AbstractCore stability exercises are regular part of exercise programs for asymptomatic individuals across ages. The purpose of this study was to examine deep abdominal and multifidus muscle thickness in children and adults and to determine reliability of the rehabilitative ultrasound (RUSI) imaging. Transversus abdominis and lumbar multifidus thickness at rest and during core stability exercise were examined in pre-pubertal children (N = 23), adolescents (N = 20), young adults (N = 21) and middle-aged adults (N = 22). Thirty-nine participants were re-tested one week after to establish reliability. Muscle thickness at rest was lower in children and adolescents compared with young and middle-aged adults (p < 0.008). Young adults displayed the highest relative transversus abdominis thickness upon contraction (p < 0.008). Lumbar multfidus contraction thickness was greater in young-adults than middle-aged adults and pre-pubertal children (p < 0.008), but it was similar between young-adults and adolescents (p > 0.008). Reliability was high for both muscles (ICC3,3 = 0.76 - 0.99). The age-related differences in muscle thickness indicate that core stability exercises may be beneficial for children and middle-aged adults.

: Sustained attention (SA) is a construct of cognition that tends to decline with age. There is a lack of literature regarding the neural correlates of SA in middle age, a link between young and old age. This study evaluated the differences in SA ability and its neural correlates using functional near-infrared spectroscopy (fNIRS) between young and middle-aged adults. 38 young and 25 middle-aged adults were evaluated for the changes in neural correlates (oxy and deoxyhemoglobin concentration in the prefrontal cortex) during a SA task known as cognition. The results showed that young adults performed significantly better than middle-aged adults on the SA task with no gender difference in their performance. There was a significant difference in the prefrontal activation pattern between young and middle-aged adults. We found right prefrontal dominance in young adults and left the prefrontal authority in middle-aged adults. This study concludes that the ability to maintain SA diminishes with age, advancing from young to middle age. Hemodynamic findings confirmed significant differences in neural resources in the prefrontal cortical areas between young and middle age. Findings document the neurobiological basis of age-related decline in the middle-aged population to understand changes in the brain's functioning during SA-related cognitive tasks.

Abstract Background: Scoliosis is common in students with a prevalence of 1-2% in teenagers and more than 50% in adults ≥ 60 years. The aim was to compare the abdominal and multifidus muscles size in adults with and without scoliosis. Methods: Forty men with and without scoliosis were recruited. The Visual Analogue Scale and the Oswestry Disability Questionnaire were used to evaluate the pain intensity and functional disability in the patients’ group, respectively. Subjects were asked to lie down in a supine position with their knees bent to measure abdominal muscles using sonography. The linear transducer was placed vertically on the anterolateral abdominal wall to record images of the abdominal muscles (Transversus abdominis, internal oblique, external oblique). To assess the lumbar multifidus muscle size, the curvilinear head was used horizontally on the multifidus muscle at the L5-S1 level in a prone lying position. Results: No significant difference was found between the two groups for demographic variables. A significant difference was found between the healthy subjects and patients with scoliosis for right and left abdominal and multifidus muscles size (p<0.05). No significant difference was reported between the two sides of the convexity and concavity on muscles size in patients with scoliosis (p>0.05). Conclusions: According to the results, patients with scoliosis had smaller abdominal and lumbar multifidus muscles size, but no significant differences were found between the muscle size of the concave and convex sides in the scoliosis group. Future work is needed to support the findings of the current study.

Abstract Objective We conducted a cross-sectional study to examine age-¬related differences in performance on a new test assessing memory for “who, when, and where” and associations among these elements. The test was designed to assess aspects of episodic memory by simulating an everyday experience of meeting a series of different people in different places across time. Method Healthy young (ages 18¬-25), middle-aged (ages 40-55), and older adults (ages 60+) were asked to remember a sequence of pictures of different faces paired with different places. After viewing the sequence, the participants were asked to pair each face with the correct place and put the face-place pairs in the correct sequence. Participants also completed a battery of standardized neuropsychological tests. Results Young adults remembered significantly more face-place pairs in the correct sequence than middle-aged (p < .05) and older adults (p < .05). There were no significant differences between middle-aged and older adults in the number of face-place pairs in correct sequence. Furthermore, young adults remembered significantly more face-place pairs irrespective of sequence than older adults (p < .05). There were no significant differences between young and middle-aged adults or between middle-aged and older adults in the number of correct face-place pairs irrespective of sequence. Conclusions Using a new test that incorporates aspects of episodic memory, we found evidence for age-related differences in test performance beginning in middle age. We found that performance on the test correlated with performance on standardized measures of verbal memory and executive functioning but not visual confrontation naming.

Age-related mobility research often highlights significant mobility differences comparing neurotypical young and older adults, while neglecting to report mobility outcomes for middle-aged adults. Moreover, these analyses regularly do not determine which measures of mobility can discriminate groups into their age brackets. Thus, the current study aimed to provide a comprehensive analysis for commonly performed aspects of mobility (walking, turning, sit-to-stand, and balance) to determine which variables were significantly different and furthermore, able to discriminate between neurotypical young adults (YAs), middle-aged adults (MAAs), and older adults (OAs). This study recruited 20 YAs, 20 MAAs, and 20 OAs. Participants came into the laboratory and completed mobility testing while wearing wireless inertial sensors. Mobility tests assessed included three distinct two-minute walks, 360° turns, five times sit-to-stands, and a clinical balance test, capturing 99 distinct mobility metrics. Of the various mobility tests assessed, only 360° turning measures demonstrated significance between YAs and MAAs, although the capacity to discriminate between groups was achieved for gait and turning measures. A variety of mobility measures demonstrated significance between MAAs and OAs, and furthermore discrimination was achieved for each mobility test. These results indicate greater mobility differences between MAAs and OAs, although discrimination is achievable for both group comparisons.

Age-related elevations in proinflammatory cytokines, known as inflamm-aging, are associated with shorter immune cell telomere lengths. Purpose. This study examined the relationship of plasma PTX3 concentrations, a biomarker of appropriate immune function, with telomere length in 15 middle-aged (40-64 years) and 15 young adults (20-31 years). In addition, PBMCs were isolated from middle-aged and young adults to examine their capacity to express a key mechanistic component of telomere length maintenance, human telomerase reverse transcriptase (hTERT), following ex vivo cellular stimulation. Methods. Plasma PTX3 and inflammatory cytokines (i.e., IL-6, IL-10, TGF-β, and TNF-α), PBMC telomere lengths, and PBMC hTERT gene expression and inflammatory protein secretion following exposure to LPS, PTX3, and PTX3+LPS were measured. Results. Aging was accompanied by the accumulation of centrally located visceral adipose tissue, without changes in body weight and BMI, and alterations in the systemic inflammatory milieu (decreased plasma PTX3 and TGF-β; increased TNF-α (p≤0.050)). In addition, shorter telomere lengths in middle-aged compared to young adults (p=0.011) were negatively associated with age, body fat percentages, and plasma TNF-α (r=−0.404, p=0.027; r=−0.427, p=0.019; and r=−0.323, p=0.041, respectively). Finally, the capacity of PBMCs to increase hTERT gene expression following ex vivo stimulation was impaired in middle-aged compared to young adults (p=0.033) and negatively associated with telomere lengths (r=0.353, p=0.028). Conclusions. Proinflammation and the impaired hTERT gene expression capacity of PBMCs may contribute to age-related telomere attrition and disease.

Background. Traumatic spinal cord injury (SCI) is a lesion that can affect several spinal structures, including the vertebrae, spinal cord, ligaments, and other adjacent parts of the spine. Traumatic spinal cord injury (SCI) can cause functional changes in patients of different ages. Material and methods. The study aims to determine whether there are social, clinical, and radiological differences between young, middle-aged, and elderly adults with SCI caused by a ground-level fall. This retrospective study analyzed the records of patients with a clinical diagnosis of SCI. It enrolled patients with traumatic spinal cord injury after a ground-level fall divided as follows: young aged adults 18–35 years of age (G1); middle-aged adults aged 36–60 years (G2); and elderly adults aged over 60 years (G3). Their clinical, social, and radiological variables were analyzed. Results. It is observed that low schooling level, being widowed, and being a homemaker were more frequently encountered among elderly adults, whereas being single was more common in middle-aged adults. The morphologic diagnosis of compression fracture and the associated injury of facial trauma occurred more frequently in elderly adults, with an increasing tendency with age. Conservative therapeutic management was most commonly encountered in elderly adults, compared to surgery from a posterior approach in middle-aged adults. Listhesis was better identified in middle-aged adults by computed tomography (CT). Spinal cord contusion and injury to the C1 vertebra were demonstrated in young adults by magnetic resonance imaging (MRI). Conclusions. 1. Elderly adults with low education level, widowed, and homemakers were more susceptible to SCI caused by a fall. 2. Single marital status was more frequently noted in young adults. 3. The most frequent clinical aspects were the morphological aspect of compression fracture and fa­cial trauma as an associated injury in elderly adults, with the occurrence of facial trauma increasing with age. 4. Conservative therapeutic management was more common in elderly adults than surgery from a po­sterior approach in middle-aged adults. 5. Re­garding the radiological aspects of CT, listhesis was better identified in middle-aged adults. Spi­nal cord contusions and C1 vertebra lesions were better identified in young adults by MRI.

Introduction: Pericardial adipose tissue (PAT), an ectopic adipose depot surrounding the coronary arteries, is a pathogenic risk factor for cardiometabolic disease; however, the association of sedentary behavior with PAT is poorly understood. We examined the longitudinal association of 10-year change in TV viewing with concurrent change in PAT. Hypothesis: Increased h/day of TV viewing over 10 years are associated with larger mean increases in PAT during the same 10-year period. Methods: Middle-aged adults (N=1659, mean age=40.4, 912 females, 733 blacks) from the Coronary Artery Risk Development in Young Adults (CARDIA) Study at the exam years 15 (2000-2001) and 25 (2010-2011) were included. Both TV viewing (h/day) and the volume of PAT (mL) were measured at Years 15 and 25 using the CARDIA physical activity questionnaire and computed tomography, respectively. Covariates measured at year 15 included PAT, sociodemographic factors, cardiovascular disease risk factors, diet quality, TV viewing, moderate-to-vigorous intensity physical activity (MVPA), inflammatory cytokines, and waist circumference. Multivariable linear regression was used to estimate 10-year change in PAT across increasing tertiles (≤ -1, > -1 to < 1, ≥ 1 h/day) of 10-year changes in TV viewing. Results: On average, TV viewing and PAT increased between the two exam years by 0.2 h/day (8.7% increase, mean: 2.3 → 2.5 h/day) and 11.8 mL (25.9% increase, mean: 45.6 → 57.4 mL), respectively (all p < 0.01). In the fully adjusted model including MVPA and other major confounders, the highest tertile of 10-year change in TV viewing was associated with greater change in PAT (β = 2.97 mL, p < 0.01) when compared with the lowest tertile (see Figure 1 ), while mean PAT change was intermediate in the middle tertile. Conclusions: A greater 10-year increase in TV viewing is associated with a greater concurrent increase in PAT, independent of MVPA and other important confounders. Reducing TV viewing time may be associated with less PAT accumulation with age.
