The contentment of the patient is a matter of fact after a person receives a service and provides some good assessment of the services. National Health Insurance (JKN) is a Government Program that aims to provide health insurance for all Indonesians. In 2019, the Ende city health center effectuated a survey regarding the extent of contentment of Ende city residents and the results revealed that there is a lot of lamentation that is perceived such as unsociable health workers, the retardation in handling their duties, the services that are still complicated, the unsanitary environment, the cramped waiting room, the long queue counter, and the lack of infrastructure such as the seat and parking lot. This research intends to ascertain the extent of contentment of the JKN participant's patient's contentment at the end city health center. This sort of research exerts the quantitative study specifically the descriptive survey method with a cross-sectional research design. The results of the study showed that 99.5% of JKN participant patients were satisfied with the quality of services, and only 0.5% were dissatisfied, As seen from the distribution of contentment levels, the tangible dimensions of 92% of respondents were satisfied and 8% was dissatisfied, the reliability dimensions of 95% respondents were satisfied and 5% was not satisfied, the responsiveness dimensions of 94,% respondents were satisfied while 5.8% were dissatisfied, the assurance dimension was satisfied by 95.85% respondents and 4.15% was not satisfied, the dimensions of empathy of respondents were satisfied by 95.85% respondents while 4.15 was not satisfied. Ende City Health Center is expected to be communicative and hospitable during the service process at Ende City Health Center, extend the time of attendance and it is necessary to conduct periodic and accurate surveys of contentment levels to maintain service quality by the Regulation of the Minister of Health of the Republic of Indonesia of 2016 concerning Health Service Standards which states that the fulfilment of service quality for each type of basic service in Health SPM should stand on the top of 95% or equivalent to 100%.

Published: July 2024

Background: Neuroinflammation in Alzheimer’s disease is known as an important process in the disease, yet how microglial activation affects disease progression remains unclear. Objective: The current study aims to interrogate the predictive value of neuroinflammation biomarker (11C-PBR28 PET), together with A/T/N imaging markers on disease deterioration in a cognitively impaired patient cohort. Methods: The study included 6 AD and 27 MCI patients, who had MRI, 11C-PBR28, 18F-flutemetamol (amyloid marker), 18F-AV1451 (tau marker) PET scans, and were followed up with multiple neuropsychological assessments for at least one year (1.6 and 2.8 years on average for AD and MCI). The predictive values of imaging biomarkers on baseline and longitudinal cognition were interrogated using linear regression to identify the biomarkers that could explain disease progression. Results: Linear mixed models found the average intercepts (baseline) MMSE were 23.5 for AD and 28.2 for MCI patients, and the slope of MMSE (annual change) were –0.74 for AD and –0.52 for MCI patients. White matter microstructural integrity was predictive of baseline cognition, while PET markers of amyloid, tau and neuroinflammation were predictive of longitudinal cognitive decline. Both amyloid and neuroinflammation PET markers were predictors independent of each other. And a sub-group analysis showed the predictive effect of neuroinflammation on cognitive decline is independent of amyloid and tau. Conclusions: Our study highlights the prognostic value of disease specific markers (amyloid, tau and neuroinflammation) in clinically diagnosed AD and MCI patients and suggests that the effects of these molecular markers are mediated by structural damage to the brain.
Could Accelerated Long-Term Forgetting Be a Feature of the Higher Rate of Memory Complaints Associated with Subjective Cognitive Decline? An Exploratory Study
Authors: Rodini Marta , Bonarota Sabrina , Serra Laura , Caltagirone Carlo , Carlesimo Giovanni Augusto 
Published: July 2024

Background: Recently, subjective cognitive decline (SCD) was proposed as an early risk factor for future Alzheimer’s disease (AD). Objective: In this study, we investigated whether accelerated long-term forgetting (ALF), assessed with extended testing intervals than those adopted in clinical practice, might be a cognitive feature of SCD. Using an explorative MRI analysis of the SCD sample, we attempted to investigate the areas most likely involved in the ALF pattern. Methods: We recruited 31 individuals with SCD from our memory clinic and subdivided them based on their rate of memory complaints into mild SCDs ( n = 18) and severe SCDs ( n = 13). A long-term forgetting procedure, involving the recall of verbal and visuo-spatial material at four testing delays (i.e., immediate, 30 min, 24 h, and 7 days post-encoding) was used to compare the two sub-groups of SCDs with a healthy control group (HC; n = 16). Results: No significant between-group difference was found on the standard neuropsychological tests, nor in the immediate and 30 min recall of the experimental procedure. By contrast, on the verbal test severe SCDs forgot significantly more than HCs in the prolonged intervals (i.e., 24 h and 7 days), with the greatest decline between 30 min and 24 h. Finally, in the whole SCD sample, we found significant associations between functional connectivity values within some cortical networks involved in memory (default mode network, salience network, and fronto-parietal network) and verbal long-term measures. Conclusions: Our preliminary findings suggest that long-term forgetting procedures could be a sensitive neuropsychological tool for detecting memory concerns in SCDs, contributing to early AD detection.

Authors: Roussel Marie-Pier , Ravel-Chapuis Aymeric , Gobin Jonathan , Jasmin Bernard J. , Leduc-Gaudet Jean-Philippe , Gagnon Cynthia , Duchesne Elise 
Published: July 2024

Background: Myotonic dystrophy type 1 (DM1) is a slowly progressive disease caused by abnormal CTG repetitions on the dystrophia myotonica protein kinase ( DMPK) gene. Long mRNA from CTG repetitions stabilizes in nuclear foci and sequester muscleblind-like splicing regulator 1 (MBNL1). Cardinal signs of DM1 include muscle wasting and weakness. The impacts of DM1 progression on skeletal muscle are under-researched. Objective: Identifying physiopathological markers related to maximal strength loss over time in DM1. Methods: Twenty-two individuals with DM1 participated in two maximal isometric muscle strength (MIMS) evaluations of their knee extensors and two vastus lateralis muscle biopsies, 3 years apart. Muscle fiber typing, size (including minimal Feret’s diameter [MFD] and atrophy/hypertrophy factors [AF/HF]), and nuclear foci and MBNL1 colocalization (foci/MBNL1+) were evaluated. Immunoblotting was used to measure glycogen synthase kinase-3 beta (GSK3 β), p62, LC3BI, LC3BII, and oxidative phosphorylation proteins. Results: There are significant correlations between the fold changes of MIMS with type 1 fiber MFD ( ρ= 0.483) and AF ( ρ= –0.514). Regression analysis shows that baseline percentage of foci/MBNL1+ nuclei and strength training explain 44.1% of foci/MBNL1+ nuclei percentage variation over time. There are fair to excellent correlations between the fold changes of MIMS and GSK3 β ( ρ= 0.327), p62 ( ρ= 0.473), LC3BI ( ρ= 0.518), LC3BII ( ρ= –0.391) and LC3BII/LC3BI ( ρ= –0.773). Conclusion: Type 1 MFD decrease and AF increase are correlated with MIMS loss. There seems to be a plateau effect in foci/MBNL1+ nuclei accumulation and strength training helps decrease this accumulation. Autophagy marker LC3BII/LC3BI ratio has a good biomarker potential of MIMS loss, but more investigations are needed.
A qualitative research of factors that predict discontinuation or non-use of assistive devices in people with hearing loss and deaf people
Authors: Jiménez-Arberas Estíbaliz 
Published: July 2024

BACKGROUND: Deaf people using sign and/or spoken language and hearing-impaired people using spoken language face frequent difficulties in activities of daily living due to the communication barriers. Among the main strategies to compensate or mitigate these difficulties we find assistive devices: video relay services, cochlear implant, audio induction loop, FM system, hearing aids. OBJECTIVE: This study aimed to explore factors contributing to assistive technology abandonment among deaf individuals who use sign language within the deaf community and those who use spoken language. METHODS: A non-experimental, cross-sectional, correlational design was used for the study. A semi-structured interview guide in the form of an ad hoc questionnaire containing 10 questions based on the International Classification of Functioning, Disability and Health. The study was carried out in Salamanca (Spain) in the association SADAP (Association of Postlocution Hearing Loss People) and CCSS (Salamanca Cultural Center for the Deaf). RESULTS: A total of 36 people participated in the study: 6 deaf people, 9 hearing loss people, 8 relatives and 13 professionals. CONCLUSIONS: The most common factors leading to assistive technology abandonment among deaf and hearing-impaired individuals include negative perceptions of the product, malfunction issues, high maintenance costs, insufficient training, and the stigma associated with its use. SIGNIFICANCE: There is a scarcity of studies within occupational therapy focusing on individuals with hearing loss, particularly those who communicate through sign language. This population often faces activity limitations and participation restrictions. While assistive products and technologies can enhance their daily functioning, negative factors that result in abandonment or discontinuation of use remain significant concerns.

More personal values, better soft skills: An explorative study with a group of Italian university students
Authors: Russo Claudia , Culcasi Irene , Barni Daniela , Cinque Maria 
Published: July 2024

We live in a complex social world characterized by high levels of job insecurity and ever-changing work trends. In this context, hard skills alone are not enough to be hired and promoted, and soft skills have become a "musthave" for students and job seekers. Several research highlighted the positive role of some active learning methods in developing soft skills such as servicelearning.However, personal characteristics might make people prone to be more skilled in specific areas than others. Thus, the present study aims to investigate the association between personal values and soft skills in a group of Italian university students. Two hundred forty-eight university students (women = 79.0%; Mage = 22.96, SD = 3.23) took part in the study. Participants completed the Portrait Values Questionnaire and the ERASMUS+K2 eLene4work Scale. Path analysis findings show several associations between the study's variables. Personal-focused values are mainly associated with intrapersonal soft skills, while social-focused values are primarily related to interpersonal soft skills. Further significant relationships between values and soft skills emerge, especially in the case of openness to change and self-transcendence values. Limitations of the study, future research developments, and practical implications of the results are discussed.
Queering as Process
Authors: Aphramor Lucy 
Published: July 2024

This article is a composite narrative case study exploring my experience of facilitating workshops around food and eating with participants who have a conflicted relationship with food or are confused by nutrition messages. Many of the workshops have been with queer, especially trans and gender-expansive, participants. I use a Freirean, interactive, story-based teaching style that I call ‘kitchen table pedagogy’.

An aim is to investigate any role that thinking beyond the binary - or queering as process - may have in helping us relate to food and our bodies in new ways that are more conducive to personal flourishing as entangled with collective liberation and hence climate justice. I illustrate how a liberatory pedagogy and queer praxis address the root of oppression by considering the provocation “How does public health nutrition perpetuate a racist, capitalist cisheteropatriarchal world view as normal, desirable, inevitable and how can queer(ing) food narratives interrupt this drive and replace it with something liberatory and life-affirming?”
