The role of walnuts (Canarium indicum L.) towards reducing blood cholesterol levels in hyperlipidemic

Hyperlipidemia is a cardiovascular disease that causes about 18% of cerebrovascular disease and about 56% of heart disease worldwide. High cholesterol levels lead to accumulation of cholesterol. Walnuts have the potential to lower cholesterol levels. The purpose of this study was to measure the effect of walnut consumption in hyperlipidemic patients on lowering cholesterol. This is an experimental research with pre-post test control group design. The research sample in the first year was mothers who had blood cholesterol levels of 200 mg/dl (hypercholesterolemia). A total of fifty (50) mothers consisting of 2 (two) groups, with 25 mothers as the treatment group and 25 mothers as the control group. Statistical analysis using test paired t-test was used to see the difference in the cholesterol levels before and after the intervention of each group. Cholesterol levels in the treatment group decreased from 242.60 mg/dl to 208.12 mg/dl and in the control group from 248.60 mg/dl to 243.16 mg/dl. The results of the paired T-Test analysis in the treatment group showed a value of p = 0.00 meaning that there was a significant difference in cholesterol levels before and after the intervention in the treatment group. In the control group the value of p = 0.75 means that there is no significant difference in cholesterol levels in the control group. Feeding 50 grams/day walnuts for 8 weeks give effect to significant reduction of cholesterol levels in hyperlipidemic mothers.

The Father's Part: A Pilot Evaluation of a Father-Centered Family Intervention Group in Child and Adolescent Psychiatry.

Changes in parental roles have renewed the focus on a father's involvement in an offspring's psychological development. However, fathers are still under-represented in family research. There are only a few structured father-centered intervention programs in child and adolescent psychiatry. In a German population sample, a pilot father-centered family intervention program with n = 16 participants, conducted in person (n = 8) and online (n = 8), in a child and adolescent psychiatry inpatient/day clinic setting was evaluated by comparing paternal stress, PSE, and child-rated paternal competence in a pre-post design. Participating fathers showed significant decreases in child-related parenting stress (presence: p = 0.042, online: p = 0.047) and significant increases in PSE (p = 0.006/0.012). Parent-related stress and child-rated paternal competence were unaffected (p = 0.108/0.171; p = 0.167/0.101), while small-to-medium effect size measures pointed in the direction of our hypothesis (d = 0.48/0.36; d = 0.37/0.50). Participant satisfaction was higher in person than online (p = 0.008). As social and biological fathers have important influences on child and adolescent well-being and development, they should be included more frequently in prevention and intervention programs. Fathers seem to benefit from gender-specific intervention programs with regard to stress reduction, as well as experiencing competence- and PSE-increasing effects.

The association of the Affordable Care Act with nutrient consumption in adults in the United States.

The Patient Protection and Affordable Care Act, more commonly known as the ACA, was legislation passed in the United States in 2010 to expand access to health insurance coverage for millions of Americans with a key emphasis on preventive care. Nutrition plays a critical role in overall wellness, disease prevention and resilience to chronic illness but prior to the ACA many Americans did not have adequate health insurance coverage to ensure proper nutrition. With passage of the ACA, more individuals received access to nutritional counseling through their primary care physicians as well as prescription vitamins and supplements free of charge. The objective of this study was to evaluate the impact of a national health insurance reform on nutrient intake among general population, including more vulnerable low-income individuals and patients with chronic conditions. Using data from the National Health and Nutrition Examination Survey (NHANES), we identified 8,443 adults aged 21 years and older who participated in the survey before (2011-2012) and after the ACA (2015-2016) implementation and conducted a subgroup analysis of 952 respondents who identified as Medicaid beneficiaries and 719 patients with a history of cancer. Using pre-post study design and bivariate and multivariable logistic analyses, we compared nutrient intake from food and supplementation before and after the ACA and identified risk factors for inadequate intake. Our results suggest that intake of micronutrients found in nutrient-dense foods, mainly fruit and vegetables, has not changed significantly after the ACA. However, overall use of nutritional supplements increased after the ACA (p = 0.05), particularly magnesium (OR = 1.02), potassium (OR = 0.76), vitamin D (both D2, and D3, OR = 1.34), vitamin K (OR = 1.15) and zinc (OR = 0.83), for the general population as well as those in our subgroup analysis Cancer Survivors and Medicaid Recipients. Given the association of increased use of nutritional supplements and expansion of insurance access, particularly in our subgroup analysis, more research is necessary to understand the effect of increasing access to nutritional supplements on the overall intake of micro- and macronutrients to meet daily nutritional recommended allowances.

Journaling your challenges: mechanisms of resilience journals to support German first-semester business students during their transition to university

Transition to university can be challenging, but writing interventions can be a helpful way of supporting first-semester students. Why these interventions are effective is still not fully understood, however. To explore the underlying mechanisms, two versions of a resilience journal were used in this study. They were designed to either broaden attention toward all challenges or to prime students’ attention to successfully mastered challenges. It was hypothesized that priming toward mastery is more effective but that both versions would increase students’ resilience and satisfaction. Hypotheses were tested in a pre-post design with 62 first-semester students randomly filling out one of the two versions for 6 weeks. The outcomes were compared to students without an intervention, and journal entries were analyzed for challenges and coping strategies. A content analysis of the journal entries revealed that most challenges were directly related to university. Problem-focused coping strategies were most often used to address challenges. Both intervention groups showed a decrease in life satisfaction during the first 6 weeks of university, but the intervention designed to broaden attention was more effective in mitigating this decrease. The same intervention was also more advantageous in promoting students’ resilience. The results highlight the vulnerability of students during their transition to university and the potential of writing interventions that include reflection on all challenges.

ACCEPTABILITY OF A REMINISCENCE THERAPY TABLET APP: IMPACT ON RESIDENTIAL CARE STAFF OF PERSONS LIVING WITH DEMENTIA

Abstract With dementia prevalence rapidly on the rise and no viable pharmacological treatments currently available, the development of accessible, efficacious, and low-cost non-pharmacologic interventions for persons living with dementia (PLWD) has become critical. Reminiscence therapy (RT) and life story can be built into residential care provision to provide person-centered solutions that elicit conversation, engagement, and socialization with staff. RT tools can also help inform care staff about residents’ lives and preferences to provide higher quality and meaningful interactions. This paper details the development and evaluation of LifeBio Memory, a tablet application designed to record the life stories and care preferences of PLWD in residential care communities. Care staff (n = 60) from 10 communities in Ohio, including memory care, assisted living and nursing homes, were trained to implement LifeBio Memory in their organizations. A pre-post design was used with staff, mainly comprised of life enrichment, administration, social work, rehab, and direct care staff. Outcomes presented include but will not be limited to: 1) acceptability, feasibility, and satisfaction with the tablet app, 2) staff knowledge of resident care preferences and interests, 3) utilization of person-centered care practices, 4) quality of communication between the resident and themselves and other staff, 5) their current understanding of that resident’s life history, and 6) level of tension and frustration with the resident. Discussion will focus on the need for sustainable RT interventions that promote person-centered care for PLWD and ways in which technological advancements can be integrated into residential care staff workflow.

MENTAL HEALTH FIRST AID TRAINING: EVIDENCE OF ITS EFFECTIVENESS FOR MENTAL HEALTH PROMOTION AMONG OLDER ADULTS

Abstract Background About 15% of adults aged 60 and over have a mental health disorder. However, stigma and lack of knowledge of mental health resources act as barriers for them to seek professional help. Mental Health First Aid (MHFA) is an evidence-based program that teaches participants how to identify, understand and respond to signs of mental illnesses and substance use disorders. The Older Adults version of this training focuses on the unique experiences and needs of older adults. This study evaluated the effectiveness of a Substance Abuse and Mental Health Services Administration (SAMHSA) funded MHFA training program among older adults. Method: Data were collected from MHFA training sessions delivered to 27 staff and 36 residents at two assisted living facilities from January to March 2023. A quasi-experimental, pre-post design was used. Two outcomes mental health literacy and stigma were measured at the pretest, posttest, and 4 months after the the training. A paired sample t-test was performed to test the differences between the pre- and post-test. Results Statistically significant improvements in self-confidence in promoting help-seeking and reduction in stigmatizing attitudes were observed among participants in post-tests and 4-month tests. Participants reported increased knowledge in how to provide initial support to someone who may be mental health crisis and help connect them to the appropriate care. Conclusion Results indicate MHFA is likely to improve mental health awareness and reduce stigma among older adults. This study adds new evidence to the literature on the MHFA program’s effectiveness among older adults and their caregivers.

NAVIGATING CAREWORKER CURRICULUM REVISION IN SOUTH KOREA: CHARTING COURSES FOR ELEVATING PRACTICE COMPETENCIES

Abstract The purpose of this study is to comprehensively investigate and analyze the process of revising the careworker curriculum in South Korea with a primary focus on augmenting practice competencies. This research involved an analysis of the existing 240-hour curriculum, complemented by a comprehensive literature review. Additionally, Focus Group Interviews were conducted with a cohort of 20 present careworkers to effectively identify the prevailing needs within the practice field. This study expanded the curriculum duration from 240 to 320 hours. Subsequently, pilot courses were executed, incorporating enhanced content related to dementia care, humanity in caregiving, and infectious disease management. These modifications were delivered via webinars to 64 active care workers, a method chosen due to the constraints imposed by the COVID-19 pandemic. This study employed a pre-post design to inquire about the perceptions of older adults and their job skills. Fifty-four female care workers (84.2%) and eleven male care workers (15.8%) participated in the study, with an average age of 52 years, experiencing 3 years and 8 months. Several areas exhibited statistical significance; understanding and managing depression and anxiety (2.175*), supporting leisure activities(2.956**), implementing abuse prevention behaviors (3.187**), creating a safe environment(2.496**), assisting with mobility(2.978**), aiding in illness management(2.805**), transferring responsibilities(2.726**), documenting cases(2.238*), and overseeing caregiver health and safety(2.805*). Based on our findings, we have devised a plan to incorporate the following content within the additional 80 hours. In a broader context, this study contributes to the ongoing discourse on caregiver education and training in South Korea.

A community-based awareness program improves knowledge and attitudes toward epilepsy: An interventional study

ObjectiveLittle interventional studies were conducted to improve knowledge, improve attitude, and eliminate stigma against patients with epilepsy. This study was conducted to investigate the effect of a community-based epilepsy awareness program (CBEAP) on knowledge, attitude, and stigma against patients with epilepsy among the Palestinian general public. MethodsThis interventional study used a pre-post design. Knowledge and attitudes were assessed using a reliable and internally consistent questionnaire before and 1 month after receiving a CBEAP. Knowledge was assessed using a 16-item and attitudes were assessed using 13 items. ResultsA total of 150 participants completed the questionnaire before the CBEAP. Of those, 136 (90.7 %) completed the CBEAP, and 129 (86.0 %) completed the questionnaire 1 month after receiving the CBEAP. The CBEAP significantly (p-value < 0.05) increased knowledge about the nature of epilepsy and seizures, triggers and treatment options, and patients with epilepsy. Similarly, the CBEAP significantly (p-value < 0.001) improved the attitudes of the participants toward epilepsy or having epilepsy, patients with epilepsy, relationships with patients with epilepsy, and working or staying with patients with epilepsy. Greater changes in knowledge and attitude scores were predicted by younger age and having a close friend or family member with epilepsy. ConclusionThe CBEAP developed and implemented in this interventional study significantly increased the knowledge of the participants about epilepsy and improved their attitudes toward epilepsy and patients with epilepsy. Large-scale implementation of such interventional programs is still needed to increase knowledge and improve attitudes toward epilepsy and patients with epilepsy.

The Impact of a School Dog on Children's Social Inclusion and Social Climate in a School Class.

Animal-assisted pedagogy is well known in classroom practice, but scientific evidence of its impact on teaching and learning conditions is still lacking. At the same time, the biggest challenge in education systems worldwide is the social inclusion of students. In a pre-post design, 30 heterogeneous students (16 f/14 m) from four different school classes (grades 5-8) of two secondary schools and one grammar school were interviewed (in a problem-centered interview) about their social inclusion and their social climate in class before and after being taught selected subjects with a school dog for one school term. At the second measurement point, participants were also asked about their perception of animal-assisted pedagogy. The qualitative data analysis (Kuckartz) showed that the presence of a dog leads to an improved social climate, more social integration and to a change in social roles; therefore, we discussed our findings in the context of role theory (Krappmann). In addition, we found that the mutual perception of the other students and the teacher changes to a more positive and friendlier image. Through animal-assisted pedagogy, a new social role is added to the classroom, where caring and bonding are prioritized. Social interaction and norms are influenced and stereotypical and individual roles can be changed. Therefore, animal-assisted pedagogy can be key to promoting social inclusion in the school environment.

Pacemaker, organ or walking stick? Pre-op association with and post-op subjective perception of a deep brain stimulation device

This study was conducted in a pre-post design with a survey of patients who had undergone deep brain stimulation (DBS) as treatment for a neurological movement disorder. The aim of the study was to compare patients' expectations and beliefs before a DBS intervention with patients' subjective experience of this intervention. The longitudinal study of patients (n=132) with an indication for DBS therapy was based on a written survey at the time points of preoperative screening (pre-op) and one-year follow-up (post-op). Preoperatively, a clear majority of respondents believed DSB to be similar to a pacemaker intervention, but one year after the intervention less than one third did so, as they compared DBS to using a walking stick or glasses. The experience of DBS in the patient's own body seems to be comparable by means of individually different associations, whereby the comparison with non-invasive aids predominates postoperatively. The discussion of these descriptions in the educational interview can contribute to a realistic horizon of patients' expectations before DBS.

Effectiveness of a Developed In-House Breast Phantom in Enhancing the Knowledge of Mammographic Positioning in Radiologic Technology Students: A Quasi-Experimental Study in Thailand

Objective: This study aimed to develop an in-house breast phantom, and assess students’ knowledge and satisfaction after using it for mammographic positioning training.Material and Methods: The breast phantom was designed in a half-body shape, and constructed primarily using gelcoat resin, polyurethane foam, and thermoreversible gel. Additionally, silicone type RA-210, known for its high flexibility, tensile strength, elongation at break (620%), and ability to revert to its original shape, was incorporated. This study evaluated the effectiveness of the breast phantom utility in improving students’ knowledge through a nine-item questionnaire; employing a one-group pre-post design. The participants, consisting of 63 Radiologic Technology students, whom rated their satisfaction with the phantom for training purposes using a five-point Likert scale.Results: The mean knowledge score for the breast phantom positioning significantly improved from 5.35±1.61 points (pretest) to 7.32±1.20 points (post-test), following training (p-value&lt;0.001). The students expressed high overall satisfaction with this training aid (4.49±0.58 points).Conclusion: Our breast phantom demonstrates its potential as an effective educational tool that enhances Radiologic Technology students’ understanding of mammographic positioning. However, further research is warranted to develop more advanced phantoms and to explore alternative experimental designs for effective teaching methods.

Combined effect of myofascial release and passive stretching on plantar pressure in individual with hamstring tightness- an experimental study

IntroductionThe lower kinetic chain is known to be affected by hamstring tightness which causes biomechanical alterations. As per the literature, short hamstring might cause prolonged forefoot loading, which can cause higher repeated stress on the plantar fascia. There is evidence supporting the use of various stretching and myofascial release techniques for hamstring tightness, further research is needed to investigate their impact on plantar pressure. Hence the study aims to determine combined effect of myofascial release and passive stretching on plantar pressure in individual with hamstring tightness. MethodsThis was an experimental pre-post study design with 67 randomised screenings from asymptomatic health care science students aged 18 to 25. From this scientific survey, a sample size of 47 students having HMS tightness based on the popliteal angle were recruited using a universal goniometer. An intervention was proposed that included MFR and passive stretching in 3 sessions on alternate days. Plantar pressure of these individuals was noted by using the “Harris and Beath foot printing mat” before and after the intervention. ResultSignificant pressure changes were observed after intervention: great toe of right side (p = 0.001), toes 2 to 5 of right side (p = 0.010) and left side (p = 0.008), first metatarsal of left side (p = 0.010), lateral forefoot of right side (p = 0.019) and left (p = 0.018), medial heel (p = 0.044), and lateral heel of right side (p = 0.025). These values substantiate the enhancement in plantar pressure. ConclusionThe combined effect of Myofascial release and passive stretching in an individual with hamstring tightness resulted in a significant increase in popliteal angle and plantar pressure.

Development of an eLearning intervention for enhancing health professionals' skills for addressing COVID-19 vaccine hesitancy.

Like many countries, Greece has faced resistance to coronavirus disease 2019 (COVID-19) vaccination among residents for both the initial and booster doses. Supporting healthcare professionals with delivering brief advice on COVID-19 vaccination may assist with reaching national vaccination targets. We sought to rapidly develop, pilot test, and deploy an eLearning intervention on skills training on effective techniques for addressing COVID-19 vaccine hesitancy for primary health and social care professionals in Greece. A five-part, 1.5-h eLearning was produced in Greek which featured two behavior change techniques, Very Brief Advice (VBA) and Motivational Interviewing (MI) adapted for use in addressing COVID-19 vaccine hesitancy. Six-film-based case studies modeling the use of VBA and MI in the context of challenging scenarios typically seen in Greek health and social settings were produced for the eLearning. The CME was pilot tested using a pre-post design in a small convenience sample (n = 17) of health care professionals. Pilot study results found the training provided new knowledge (80%), improved provider skills (80%), and was useful to provider's clinical practice (90%). There was a mixed effect in provider capability, motivation, and opportunity. Ninety percent of providers strongly agreed or agreed that they planned to use the information and skills provided by the training in their clinical practice. This project has resulted in new training assets for use by health and social professional tailored to the nationally context in Greece including supporting uptake of booster doses of the COVID-19 vaccine.

Protein Supplements and Exercise for Sarcopenic Obesity: Benefits and Negative Effects

Background Protein supplements are commonly utilized by elderly persons who are suffering from sarcopenic obesity. Despite its popularity, however, there is currently a paucity of clear evidence on the possible benefits and negative effects of protein supplements and exercise on sarcopenic obesity (SO). Objective Thus, we wanted to see how protein supplementation and exercise affected older persons with sarcopenic obesity. Method A thorough database search was carried out to look for randomised controlled trials, quasi experimental studies, and pre-post research designs addressing the effects of protein supplementation on reducing sarcopenic obesity in older persons. This scoping review was carried out via PubMed, Embase, Web of Science, and the Cochrane Library databases using PRISMA-Scr protocols. Two independent reviewers conducted a thorough systematic screening approach to determine record eligibility. Results Seven papers met the inclusion criteria out of the 1,811 citations found. Six of the investigations were randomized controlled trials, while one was a pre-post test study. The majority of research addressed the usage of protein supplements as well as exercise training. The protein intake for the intervention group in the included trials ranged from 1.0 to 1.8 g/kg/BW/day, while the duration of exercise conducted ranged from 2 to 3 times per week, with each session lasting 1 hour. Whey protein supplementation has been demonstrated to improve sarcopenic symptoms and weight status in SO people. The combination of resistance training and protein supplementation produced additional benefits in terms of lean muscle mass as well as biomarkers. The study also discovered a lack of uniformity in exercise design among sarcopenic obesity therapies. Conclusion Overall, the combination of resistance training and whey protein supplementation appears to be a good alternative for SO persons seeking to enhance their sarcopenic state and weight status. It does, however, underline the need for prudence when it comes to high protein consumption prescription. Given the scarcity of studies in this area, more research into the appropriate exercise plan for this demographic is necessary.

Use of Sweet Mango Leaves (Mangifera indica) To Reduce Germs Colonies on Cutlery

According to WHO, the global death rate due to diarrhea in 2002 was 1.8 million people. Global morbidity rates due to PBM (Community Based Diseases) are very difficult to estimate. Apart from diarrhea, there are more than 250 types of diseases caused by consuming unsafe food. This study aims to determine the difference in average germ numbers before and after using soap made from mango leaf powder. This research is an experimental study with a pre-post design to determine the ability of dishwashing soap made from sweet fragrant mango leaves to reduce germ colonies. The population and sample in this study were cutlery in the form of spoons, glasses and plates, each consisting of 5 samples. Examination of the samples was carried out before and after using dish soap. Data is collected from an observation sheet which contains the number of germ colonies in each sample examined. Data were analyzed using the paired t test. This research was conducted at the Microbiology Laboratory of the Integrated Health Polytechnic Laboratory of the Ministry of Health in Ternate. The results showed that the average germ number in the pre-test was 2454.44 ± 668.70, while in the post-test the average germ number was 1178.67 ± 249.61. The P value = 0.012 (&lt; 0.05) indicates that there is a significant difference in the average number of germs before and after using soap made from mango leaf powder. The conclusion is that using soap made from mango leaf powder can significantly reduce the number of germs on the hands. This shows the potential of soap as an effective alternative in maintaining cleanliness and reducing the risk of spreading disease through hand contact.

Effect of dolutegravir-based drug combinations on the level of medication adherence and viral load among adolescents living with HIV in resource-limited setting: a pre-post design.

The use of antiretroviral drugs among HIV-infected adolescents has been challenged with poor medication adherence, leading to an unsuppressed viral load and ultimately to drug resistance. Recently, dolutegravir has been approved for use in adolescents with HIV, but the evidence on medication adherence and viral load suppression is limited. The study determined the effect of dolutegravir-based drug regimens on the level of medication adherence and viral load among treatment-experienced adolescents. A longitudinal pre-post design study was done among adolescents living with HIV at a paediatrics clinic in Nigeria. Assessment of medication adherence and viral load testing was done before and at six months of transitioning to dolutegravir-based regimens. McNemar-chi-square was used to determine the effectiveness of the drug on adherence and viral load suppression. Multivariate logistic regression analysis was performed to determine the predictors of drug adherence and viral suppression. The mean age of the participants was 14.7 years (SD=3.2), and 53.3 % were males. The mean duration of ART use was 10.3 years (SD=3.2). Six months after transitioning to dolutegravir, there was a significant decrease in viral load (Z=-7.947, p<0.001) and an increase in medication adherence score (Z=-7.554, p<0.001), among the treatment-experienced adolescents. Viral suppression was 13 times higher among respondents with good medication adherence as compared to those with poor medication adherence (AOR=13.24, CI=3.25-53.90). Dolutegravir is effective in improving medication adherence and viral suppression among Adolescents living with HIV. Thus, the need to transition eligible adolescents to dolutegravir to sustain better treatment outcomes.

The Effectiveness of Prenatal Yoga on Back Pain Intensity of Third Trimester Pregnant Women in Surakarta

The third trimester is the period of pregnancy in the last three months of pregnancy. The adaptation process that occurs during pregnancy often causes discomfort for pregnant women, so it is necessary to do several things from prevention to treatment. The most common discomfort for pregnant women is back pain. Pregnant women can experience back pain due to increased weight and spine. overcome back pain by massaging the back but it is not effective and prenatal yoga has never been done to treat back pain in the interviewed third-trimester pregnant women. The purpose of this study was to assess the effectiveness of prenatal yoga on back pain in third-trimester pregnant women. This study was a quasi-experimental design with a pre-post test control group design. The sampling technique in this study was purposive. In the implementation of this research respondents obtained as many as 30 respondents. after prenatal yoga in the third-trimester pregnant women is 2.07 with a standard deviation of 0.799. The results showed that there was an effect of prenatal yoga on the level of back pain in the intervention group before and after prenatal yoga was performed in the third trimester of pregnant women in Surakarta City in 2022 with a p-value of 0.001 (p &gt; 0.05). The reduction in back pain was highest in the intervention group because the intervention group was given prenatal yoga. Prenatal yoga affected decreasing the level of back pain in third-trimester pregnant women. Researchers recommend prenatal yoga as physical exercise for pregnant women
