Pilot testing cognitive stimulation intervention on older adults' cognitive function, cognitive self-efficacy, and sense of happiness.

BACKGROUND: With the ageing population increasing worldwide, identifying effective approaches to counteract cognitive decline becomes significant for maintaining cognitive health and quality of life in older adults. The lack of cognitive activity accelerates age cognitive decline. Cognitive stimulation interventions can maintain older adults' cognitive reserve, enhance their feelings of happiness, and potentially improve their psychosocial wellbeing. AIM: This study aimed to determine the impact of Cognitive Stimulation Intervention on older adults' cognitive function, cognitive self-efficacy, and sense of happiness. METHOD: A quasi-experimental methodological approach was applied. Two seniors' clubs were the sites for recruitment in this study as part of the Alexandria Governorate's Ministry of Social Solidarity, Egypt. Eighty older adults (aged 60 and above), randomly assigned into two equal groups. The study group received the study intervention, and the control group received regular seniors' club services. RESULTS: Cognitive function, cognitive self-efficacy, and sense of happiness scores among the study group, were significantly increased from (22.40 ± 0.67, 54.51 ± 8.63 and 27.68 ± 14.0 respectively) to (24.30 ± 1.07, 87.84 ± 4.96 and 65.98 ± 8.90 respectively) (P < 0.001) following the interventions, and were significantly higher than the control group's post-test percent scores (22.08 ± 0.98, 54.35 ± 6.97, and 28.75 ± 9.60 respectively) (P < 0.001). CONCLUSIONS: Cognitive Stimulation Intervention effectively fostered the older adults' cognitive function, cognitive self-efficacy, and sense of happiness. Consequently, seniors' clubs, care homes, and other contexts seeking to apply Cognitive Stimulation Intervention to improve older adults' cognitive function, and general wellbeing must embed this intervention as part of their routine care and social activities programs.

Using the information-motivation-behavioral skills model for targeting older adults' climate change management practices: in the road of COP27.

BACKGROUND: Climate change is a rapidly evolving public health problem warranting global attention in the 21st century. The World Health Organization declared that climate illiteracy is highly prevalent among older adults, especially in lower- and middle-income nations. AIM: To determine the effect of the Information-Motivation-Behavioral Skills Model-based intervention for climate change management practices among older adults. DESIGN: A quasi-experimental employed a pre-posttest, two-group research design. PARTICIPANTS: The studied sample comprised 80 older adults (aged 60 years and above), assigned to study and control groups (n = 40 each) after completing a baseline survey of six validated measures. RESULTS: The study group of proposed intervention based on IMB model demonstrated significant improvement in the mean scores of information (98.62 ± 3.56), motivation (90.14 ± 3.02), actual skills (84.13 ± 8.76), and practices (85.80 ± 3.94), p = 0.001. CONCLUSION: The intervention based on the Information-Motivation-Behavioral Skills Model has demonstrated credible feasibility in significantly improving the climate change-related information, motivation, skills, and management practices of older adults immediately after the posttest. It should be emphasized that this improvement showed a significant decline at the six-week mark; albeit the study participants' scores remained significantly higher than their pre-test values, there is clearly a need for reinforcement to maintain positive outcomes over the long term. The existing outcomes call for replication of this intervention in other cohorts, such as uneducated older adults and those residing in assisted-living facilities.

Comparison of palatal volume and surface changes between bone-borne and tooth-tissue-borne maxillary expansion on cone beam computed tomography digital cast models.

OBJECTIVES: To compare the changes of palatal volume and area in patients treated with tooth-tissue-borne palatal expanders (conventional Haas) and miniscrew-supported palatal expanders (modified Haas). MATERIALS AND METHODS: The sample included casts of 22 patients treated as part of a clinical study at the Department of Orthodontics, Al-Azhar University, to correct their crossbite malocclusion. Patients were divided equally into two groups upon arrival. The first group, with a mean age of 12 years and 6 months, received the miniscrew-supported palatal expander. The second group, with a mean age of 12 years and 2 months, received the Haas design-palatal expansion appliance. Pre- and post-expansion dental casts were cone beam computed tomography scanned and the slices were constructed into 3D volumes. Fully automated superimposition was done for pre- and post-expansion 3D models. Palatal volume and area were determined, and all measurements were carried out blindly. Paired t-test was used to assess the mean differences within each group and Welch's t-test was applied to assess the mean changes between the two groups. Shapiro-Wilk test was used to test for the normality of the data. RESULTS: There were no statistical differences in volume changes either within each group or between the groups. Although area changes were statistically significant within each group, the difference between the groups was not significant. CONCLUSIONS: Changes that result from the use of either method to expand the upper arch occur primarily in the shape of the palate, but not in its size.

United Reference Method for three-dimensional treatment evaluation.

BACKGROUND: Reproducible and descriptive Three-dimensional treatment evaluation can enhance future treatment based on realistic results. So, the purpose of this study was to describe a new method for three-dimensional treatment evaluation showing how to use fully-automated craniofacial superimposition of CBCT records combined with reference system to obtain descriptive and comparable results. This new method was named United Reference Method (URM). METHODS: URM is a combination of automated 3D superimposition on anterior cranial base surface anatomy and measurements based on reference system. It was developed to show how to use fully-automated superimposition to obtain descriptive numerical comparable values. The method is based on: one main reference system for both superimposed CBCT records, semi-automation to increase accuracy, all measurements are projections and auxiliary references to aid in landmarks identification and measurements. The method steps can be described following a four-step approach: (1) Superimposition performed through a fully automated, voxel-wise, rigid registration considering only cranial base as a stable structure; (2) Identification of reference landmarks once on the superimposed records for corrected Frankfort Horizontal plane (C-FH) construction and a new semi-automated constructed Sella point to correct Orbital asymmetry; (3) Head orientation of superimposed CBCT images based on the C-FH; (4) Identification of landmarks affected by treatment with the aid of auxiliary reference planes. Evaluation of linear or angular changes derived by projection of same pre- and post-treatment landmarks on the C-FH. Pre- and post-expansion CBCT scans of 20 unilateral cleft lip and palate patients were used to calculate intra and inter-rater reliability. (X, Y and Z) coordinates, mean, standard deviation (SD) and Intra-class Correlation Coefficient (ICC) were calculated. RESULTS: The proposed coordinates for C-FH construction showed ICC ≥ 0.998 and SD ranging from 0.064 to 0.242 mm. On the other hand, excluded coordinates due to expected natural craniofacial asymmetry had the lowest reliability ICC ≥0.742 and SD dramatically increased up to 1.112 mm. CONCLUSION: URM showed adequate reliability so it can be used to produce three-dimensional descriptive data of craniofacial structural changes.

Palatal volume and area assessment on digital casts generated from cone-beam computed tomography scans.

OBJECTIVES: The objective of this study was to develop a reproducible method to measure the change of palatal volume and area through superimposition using maxillary expansion digital cast models. MATERIALS AND METHODS: A total of 10 pre- and 10 postexpansion dental cast models were scanned by the same cone-beam computed tomography machine. Superimposition was performed using a fully automated surface-best fit of the palatal surfaces on the digital cast models. A gingival plane, identified only once on superimposed casts, and a distal plane with the lateral closing border and the palatal surface were used to localize this selection of air. Area and volume were calculated for pre- and postexpansion records. Pre- and postexpansion palatal volume and area were measured by the main investigator and three different observers for inter- and intra-observer reproducibility assessment. RESULTS: The level of intra- and inter-observer agreement was very strong (intraclass correlation coefficients ≥ 0.953; P value < .0001) for all measurements. CONCLUSIONS: Palatal volume and area measurements based on the proposed superimposition are reproducible and can be used reliably.
