This study evaluates the effect of dual tasks on balance during manipulation of visual information, the base of support, and cognitive tasks in 7–12-year-old children and adults. An equal number of girls (210) and boys (210) were selected from the schools by the cluster random sampling method (within the 7–12 age groups). Twenty young adults were also selected. Postural sway (PS) was measured in the anterior–posterior (AP) and mediolateral (ML) directions using a force plate in eight standing positions, including standing with closed eyes versus standing with open eyes and standing with feet together versus on a single limb, under the interference of cognitive dual tasks (DT) or a single task (ST). PS was found to decrease with advancing age. PS was also greater in men than women in both AP and ML directions (p < 0.05). PS was greater in the 7–12-year-old participants compared to adults under the manipulation of the base of support (p < 0.05). However, PS increased in all participants regardless of their age while manipulating both the base of support and visual information (p < 0.05). Children (within the 9–12 years age range) and adults could keep their balance while performing basic tasks; however, children had difficulty in maintaining their balance with higher task demands.

This cross-sectional study aimed to determine the degree of visibility of maxillary and mandibular anterior teeth at rest in different age groups and to evaluate the smile line, smile arc, and number of maxillary teeth displayed during smiling among the Saudi population visiting King Abdulaziz University Dental Hospital, Jeddah, Saudi Arabia. A total of 157 participants (77 males and 80 females) were included in this study with an age range of 19 to 69 years. All participants had maxillary and mandibular anterior teeth without restorations. Crown length and visible portions of anterior teeth at rest were measured using a Fowler Electronic Digital Caliper. Three measurements of each variable were recorded by two independent dental interns and calibrating their measurements was performed. Smile line, smile arc, and number of teeth displayed during smiling were examined. The collected data were statistically analyzed using SPSS software. It was found that the average clinical crown lengths in the maxillary lateral incisor, mandibular central incisor, and canine were significantly higher in males than females. At rest position, females displayed more maxillary central and lateral incisors. The displayed length of maxillary teeth at rest is inversely proportional to increasing age; the reverse occurs in mandibular teeth. The common visibility of maxillary teeth during smiling was from the second bicuspid to its counterpart. Average smile line and consonant smile arc were the most common characteristics. It was concluded that both age and gender affect the characteristics of tooth display at rest and in smiling. These effects should be considered during treatment planning and restoration of anterior teeth to obtain a more predictable esthetic outcome.

AbstractLight touch is the combination of cutaneous and kinesthetic inputs. The literature suggests that light touch compensates for a reduced amount of center of pressure information in older peoples, blind subjects and patients with neurological disorder. This study investigated the effects of light touch applied to an external bar, on the postural sway in individuals with hemiparetic stroke. We used a cross sectional study, fifteen individuals with stroke and 15 healthy age-matched adults stood as still as possible on a force plate. Experimental trials (duration, 30 s) included two visual conditions (open eyes and closed eyes), two somatosensory conditions (no touch and light touch) and two support surface conditions (firm and foam surfaces). The area of center of pressure (COP) and the mean velocity of COP in the medio-lateral and anterior-posterior directions were assessed. For both groups, COP velocity and area decreased with light touch regardless of the visual or surface conditions. The effects of light touch were similar in both groups. In addition, results show that the effectiveness of light touch in reducing postural sway was greater on a foam surface than on a firm surface. Our findings indicate that light touch could be beneficial in postural control for individuals with hemi-paretic stroke

This study aims to determine the prevalence of hypertension among children with diabetes mellitus, and describe adherence to the standard of practice regarding early diagnosis and treatment of hypertension in this population. Diabetes renders higher susceptibility to cardiovascular disease in affected patients and thus early detection of hypertension can be beneficial for future quality of life. We hypothesize that a number of diabetic children with hypertension are not promptly diagnosed and treated due to the difficult process preceding diagnosis. This cross-sectional study in an out-patient clinic of a university hospital was based on a group of 263 children (both females and males, age range between 3-18) diagnosed with type 2 diabetes. At the visit, the child's weight and height were recorded, BMI was calculated, systolic and diastolic blood pressure (BP) was taken, and blood sample drawn for hemoglobin A1C (HbA1C) readings. Within the study population we have identified a group of 73 children with hypertension. Comparing the two groups: the normotensive with the hypertensive, we have observed that the normotensive patients have significantly lower average BMI (26.7), p=0.000012 and slightly reduced HbA1C (8.9%), p=0.28 levels compared to the hypertensive group: BMI (32.5) and HbA1C (9.3%), respectively. We investigated the same parameters within every age group starting from age 10, and recorded that HbA1C was only significantly different for the group of 14 year-olds (8.7%; 11.7%, p=0.039). We also found that a significantly higher BMI is linked with hypertension for groups: age 13: BMI (29.2; 33.9, p=0.047), age 14: BMI (24.1; 35.6, p=0.00007) and age 18: BMI (31.8; 45.6, p=0.045). Within the different age groups there were differences between normotensive and hypertensive patients in BMI and HbA1C measurements, but they were not statistically significant and we assume that an increased sample size would be needed to confirm the data. We are currently working on identifying other risk factors including sex, race, height, urine creatinine, urine microalbumin, serum creatinine, lipid profile and thyroid function, that might be responsible for hypertension in pediatric patients with type 2 diabetes.

Purpose. To investigate the association of birth parameters with refractive status in different age groups of Caucasian children.Materials and Methods. This cross-sectional study included 564 eyes of 282 children aged 4 to 17 years. All children underwent complete ophthalmologic examination. The children were divided into three groups according to their refractive status (emmetropia,myopia, and hyperopia), ages (4–7, 8-9, 10–12, and 13–17), and appropriateness for gestational age, respectively.Results. The mean age of the children was9.2±2.8(age range 4–17 years). The mean spheric equivalent was+0.3±1.7(range: (−10.0)–(+10.0) diopters). The mean birth weight and gestational age were2681.1±930.8grams (750–5000 grams) and37.2±3.7weeks (25–42 weeks). According to multinominal logistic regression analysis, children with myopia were more likely to have higher birth weights than emmetropic children (OR: 1.0, 95% CI: 1.000–1.001, andP=0.028). The hypermetropes were found to be significantly small for gestational age between 13 and 17 years of age.Conclusion. Birth weight and appropriateness for gestational age as birth parameters may have an impact on development of all types of refractive errors. The hypermetropic children tended to be small for gestational age.

Abstract The global pandemic caused by the coronavirus disease 2019 (COVID-19) had mental health consequences such as fear. Scholars have argued that when people are fearful, they may use substances to escape from fear, and demographic variables can have implications on how to target interventions to people. To date, little is known about how the fear of COVID-19 and demographic factors may contribute to substance use amid the COVID-19 pandemic. From 3 June to 10 June 2020, a cross-sectional study was conducted with 202 residents (Mean age = 41.77 ± 11.85; age range = 18-70 years) in 14 countries. A standardized questionnaire was utilized for data collection, SPSS (version 22.0) was utilized for data analysis, and p < .05 implied statistical significance. Descriptive statistics revealed that residents in Canada scored the highest mean score in the fear of COVID-19 scale, while residents in Australia scored highest in the substance use scale. Further, fear of COVID-19 had a negative nonsignificant relationship with substance use (r = −.07; df = 200; p > .05). Males (Mean = 18.21) scored significantly higher than females (Mean = 14.06) in substance use [t (200) = 1.9; p < .05]. The younger age group (18-28 years) scored the highest mean score in substance use compared to older age groups (29-39 years, 40-50 years, 51-61 years, and 62-72 years); however, it was not significant [F (4, 197) = 2.04; p > .05]. These data contribute to informing future studies that add more questions regarding how different variables may contribute to substance use during subsequent waves of the COVID-19 pandemic.

Introduction Diarrhea remains a major problem for communityhealth in Indonesia. More than 25% of children with severe diar-rhea suffer from malabsorption syndrome.Objectives This study aimed to determine the age range of chil-dren with acute diarrhea, the prevalence of macronutrient malab-sorption, and the relationship between age and bacterial infec-tion in macronutrient malabsorption.Methods This was a cross-sectional study, subjects were chil-dren aged 0-59 months with acute diarrhea whose stools wereobtained and examined in the laboratory of GastrohepatologyDivision, Department of Child Health, Cipto Mangunkusumo Hospi-tal, Jakarta from January 2002 to December 2003.Results Children with acute diarrhea were mostly in the agerange of 0-11 months (61%). The prevalence of lactose malab-sorption was 11%, carbohydrate malabsorption was 19%, andfat malabsorption was 51%. Moreover, the age group of 0-11months had a 1.5 times greater possibility of lactose and fatmalabsorption compared to that of 12-59 months. The 12-59 monthsage group had a greater possibility of suffering carbohydratemaldigestion (70%). The group of children who did not sufferfrom bacterial infection had a higher prevalence of lactose mal-absorption (54%), carbohydrate maldigestion (65%), and fatmalabsorption (58%).Conclusions Acute diarrhea occurred more frequently in theage of 0-11 months. There was a significant correlation betweenthe age groups of 0-11 months and 12-59 months in experiencingmacronutrient malabsorption. Lactose malabsorption, carbohy-drate maldigestion, and fat malabsorption were encountered morefrequently in the group that did not have bacterial infection

Abstract Objective To investigate the effect of a cognitive task on postural control during treadmill walking. We hypothesized that postural sway acceleration would decrease during dual-task compared to single-task gait. Method Ten (5 females, 5 males) physically active, healthy young adults (Age: 22.50 ± 3.01) with no history of cognitive deficits or head injury were recruited from a University campus for this cross-sectional study. Participants reported to a biomechanics laboratory for a single testing session and completed two, 5-minute walking trials on a treadmill at 90% of maximal gait-speed under single and dual-task conditions while instrumented with a single inertial measurement unit (IMU) on the lower-back. During dual-task gait, participants concurrently performed a Stroop Test displayed on a mounted screen in front of the treadmill during the entire trial. Root mean square (RMS) of acceleration was analyzed in the medial-lateral, anterior-posterior, superior-inferior, and resultant planes during the dual-task trial. Paired t-tests and effect sizes (ES) were calculated for each sway plane between single and dual-tasks. Results No differences were identified between single and dual-task RMS acceleration in the medial-lateral (p = 0.98, ES = 0.01), anterior-posterior (p = 0.49, ES = 0.23) or superior-inferior (p = 0.98, ES = 0.01) planes. However, the RMS acceleration in the resultant plane was lower in the dual-task condition (Mean Difference: 0.031 ± 0.037; p = 0.02, ES = 0.85). Conclusions This novel dual-task gait paradigm utilized constant sub-maximal gait speed to investigate the influence of a sustained cognitive dual-task on postural sway using a single IMU. These preliminary results indicate that this dual-task gait paradigm may affect gross postural sway in healthy adults.

Objective: The purpose of this study was to investigate the gender and age effect on lung function measures and maximum phonation time in the age range of 20-60 years. The present study also aimed to evaluate correlation between FEV1 and maximum phonation time. Study Design: Cross- sectional study, Convenience sampling method Method: The lung function measures (FVC, FEV1, & FEV1/FVC) and maximum phonation time were obtained from 200 healthy participants in the age range of 20-60 years. These participants were divided into two groups (Group I - 20- 40 years & Group II - 41- 60 years) with equal number of males and females in each group. The lung function measures were obtained using Easy on PC spirometer. Three consecutive trials were collected for MPT using stopwatch. Mann- Whitney U test was used to determine effect of age and gender on lung function measures and MPD. Spearman's Rank Correlations were performed to identify is there any significant relationships between the FEV1 and MPT of /a/, /i/, /u/, /s/, and /z/. Results: There were significant effect of gender on FVC, FEV1, & MPT except on FEV1/FVC. There was significant effect of age in both genders on FVC, FEV1, & FEV1/FVC. There was no significant effect of age in both genders on MPT /i/, /u/, /s/, and /z/ except MPT /a/ for males. FEV1 showed significant positive correlation with MPD (/a/, /i/, /u/, /s/, and /z/). Conclusions: The mean FVC and FEV1 were lower in females and higher in males in both the age groups. Maximum phonation time of /a/, /i/, /u/, /s/, and /z/ was longer in males as compared to female. Age has inverse effect on lung function measure and MPT. FEV1 showed positive correlation with MPT, which indicates that FEV1 increases with increase in MPT. Key words: Maximum Phonation Time, Lung Function Measures.
