Background/Objectives The University of Alabama at Birmingham (UAB) Life‐Space Assessment (LSA) is a widely used measure of community mobility. To assist clinicians and researchers with assessing the significance of changes in scores, we determined the minimal important change associated with a change in health status. Setting Homes of community‐dwelling older adults. Participants A total of 419 African American and non‐Hispanic white adults 75 years and older participating in the UAB Study of Aging II, a longitudinal epidemiological study across the state of Alabama. Intervention None. Measurements Linear mixed models were used to compare change in LSA scores over 1‐month intervals (N = 9712) between participants reporting improvement, no change, or decline in activities of daily living walking scores, accounting for the correlation among scores for the same participant over time. Results A decline in walking status was associated with a mean decrease in LSA scores of 2.93 points (95% confidence interval [CI] = 1.69‐4.17 points), indicating lower mobility. An improvement in walking status was associated with a mean increase in LSA scores of 2.51 points (95% CI = 1.26‐3.77 points), indicating higher mobility. Conclusion A change in LSA scores of five or more is clinically important, exceeding the 95% CI for the change in LSA associated with change in walking status. Changes exceeding this threshold should prompt further investigation by providers with a goal of preserving mobility. J Am Geriatr Soc 67:565–569, 2019.

Background: The countermovement jump (CMJ) is a valid and reliable test of lower extremity (LE) muscle power. However, the CMJ may not be appropriate during early-stage rehabilitation of injuries. Functional muscle strength tests (FMSTs) could evaluate LE muscle power with lower joint reaction forces. Hypothesis: The lateral step-up test (LSUT), 5 times sit to stand (5×STS), and 30-s chair stand test (30CST) could predict CMJ jump height (JHt) and jump peak power (JPow). Study Design: Cross-sectional study. Level of Evidence: Level 2. Methods: Eighty-one young adults performed 3 CMJs to measure JHt and JPow using an electronic jump mat and speed analyzer. Participants also performed three FMSTs: 1 trial of the LSUT and a modified trial of LSUT touching the ground with the heel only (MLSUT); 2 trials of the 5×STS; and 2 trials of the 30CST, in a randomized order. Spearman rho correlations and hierarchal multiple linear regressions were used to determine whether FMST performances predicted JHt and JPow, after controlling for sex, body height, and body mass. Results: 30CST, LSUT, MLSUT, sex, body mass, and body height were significantly associated with JHt ( P < 0.05). LSUT, sex, body height, and body mass were significantly associated with JPow ( P < 0.05). Hierarchical regression analyses showed that the 30CST significantly predicted JHt ( P < 0.01) and JPow ( P = 0.03), independent of sex, body height, and body mass. Conclusion: 30CST performance predicted JHt and JPow in young adults. Clinical Relevance: The 30CST is easy to perform, requires equipment found readily in clinics, and predicts LE muscle power. This test could be used to track progress during the early stages of LE injury rehabilitation.

Odontogenic cysts (OCs) are etiologically diverse conditions with a shared origin in the jaws. Unfortunately, there is a scarcity of published data regarding OC frequency, treatment, and follow-up information in Saudi Arabia, especially from tertiary centers. Objectives: The study aims to assess the relative frequency, clinicopathological features, treatment, and follow-up of OCs in three tertiary medical centers. Methods and Material: OCs were identified from King Abdulaziz Medical City, King Fahad Medical City, and Prince Sultan Military Medical City from January 2010 to December 2021. Results: Three hundred and seventy-two cases of OCs were identified from the archive of three medical centers in Riyadh; one hundred and forty-nine (40%) cases were retrieved from Prince Sultan Military Medical City. The mean age of all OCs was 32 years (range 2–90), with 225 (60.4%) cases occurring in males. There was an almost equal distribution of OCs between the maxilla (47.0%) and the mandible (53.0%). The apical radicular cyst (ARC) accounted for half of the cases, followed by dentigerous cyst (DC) (29.3%) and odontogenic keratocyst (OKC) (14.2%). Enucleation was the most common treatment modality (52.8%), followed by excision (35.0%). Thirteen cases showed recurrence: one ARC, four DCs, and eight OKCs. Conclusion: This is the first large multicenter study of OCs in Riyadh, Saudi Arabia. All three centers showed that ARC was the most common, followed by DC and OKC.

Background: Lower body positive pressure (LBPP) may provide a novel intervention for gait training in neurological conditions. Nonetheless, studies investigating the safety and feasibility of LBPP in patients with stroke are insufficient. Objectives: The purpose of this study was to evaluate the safety and feasibility of LBPP as a rehabilitation intervention for individuals with chronic stroke. Methods: Individuals with chronic stroke were recruited from the community to participate in LBPP gait training three times a week for six weeks. The LBPP’s safety and feasibility were documented throughout the study and at the end of six weeks. Safety and feasibility referred to the incidence of adverse events, complications, the participant and therapist satisfaction questionnaire, and the device limitation including but not limited to technical issues and physical constraints. In addition, blood pressure, pulse rate, and oxygen saturation were taken pre- and post-session. Dependent t-tests were used to analyze the difference between assessments. A Wilcoxon test was used to assess the ordinal data (Trial registration number NCT04767334). Results: Nine individuals (one female, eight males) aged 57 ± 15.4 years were enrolled. All participants completed the intervention without adverse events. All participants reported positive scores from 4 (very satisfying) to 5 (extremely satisfying) in the safety and feasibility questionnaire. No significant differences were observed in blood pressure and oxygen saturation during the intervention sessions. However, significant increases were observed in heart rate from 82.6 ± 9.1 beats/min (pre-session) to 88.1 ± 6.8 beats/min (post-session) (p = 0.027). Conclusions: LBPP is a safe and feasible rehabilitation tool to use with individuals with chronic stroke.

BackgroundAttention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders that manifest among children. Despite the fact that the teacher's role is essential in the assessment and management of pupils with ADHD and the recommendation of participation of teachers for the success and efficiency of diagnoses and treatment, the vast majority of teachers have neither understanding nor knowledge of ADHD.ObjectivesThe current study explores the kindergarten and elementary school teachers’ knowledge regarding early detection and management of ADHD.MethodsCross sectional survey using stratified random sampling technique was carried out in governmental and private elementary and kindergarten schools in four cities of Qassim region, Saudi Arabia.ResultsThe study included 1095 teachers, 711 (59.3%) did not get information about ADHD during undergraduate studies. Teachers’ overall ADHD knowledge mean was 21.7 + 5.5 out of 38 marks. Teachers with high qualification degree and kindergarten specialty scored 56.4% and 60.2%, respectively. Teachers who attended conferences related to ADHD scored 64.5%, while teachers who read about ADHD or have been ever asked to diagnose/teach an ADHD student had 59.4% and 62.1%, respectively. The sources for those who got their information through reading were statistically significant in overall knowledge, general knowledge and treatment dimensions. As scientific studies and books were the highest with percentage of 24.6% and 23.3%, respectively, 4% and 3.6%, respectively, 3% and 3%, respectively. The level of ADHD knowledge perception showed that 76% of teachers were knowledgeable in relation to overall ADHD perception.ConclusionTeachers who have higher qualifications or training in identifying ADHD children scored higher in our study.Disclosure of interestThe authors have not supplied their declaration of competing interest.
