Authors: Erlinda Yuni , Marliyati Sri Anna , Setiawan Budi
Published: August 2024

Background: Hypertension, when it is not controlled, can cause complications to many diseases and death. Hypertension control can be achieved by adjusting to a healthy diet, such as increasing the consumption of fruit, whole grains, potassium intake, calcium, and magnesium. Several studies have shown that star fruit and chia seeds can control blood pressure in people with hypertension. However, the nutritional content, such as calcium and magnesium, is still relatively low in star fruit. According to USDA, chia seeds contain high level of calcium, potassium, and magnesium.

Objectives: This research aims to determine the sensory acceptability and the nutritional content of star fruit juice by adding chia seeds.

Methods: This is an experimental study with a Completely Randomized Design (CRD). There were four formulations of star fruit juice with chia seeds additions (0 g,10 g,15 g, and 20 g). The sensory analysis was tested by the Kruskal Wallis test and Mann-Whitney test. While differences of the nutritional content from the product that preferred by panelists were tested by Independent T-test.

Results: There were significant differences (p<0.05) in all sensory parameters. The selected sweet star fruit juice with the addition 10 g chia seed formulation showed an increase in nutrients except for the water content. Water content of 89.21 %, ash content of 0.32 %, carbohydrate content of 7.14 %, fat content of 1.75 %, protein content of 1.55%, potassium content of 206 mg/200 ml, calcium content of 34.84 mg/200 ml, magnesium content of 17.80 mg/200 ml, and sodium content of 2.46 mg/200 ml.

Conclusions: Sweet start fruit juice with the addition of 10 g of chia seed is the most liked star fruit juice formulation with chia seed addition by the research panellists, and it can increase the nutritional content, especially calcium and magnesium content.

Published: August 2024

Background

Digital interventions integrating gamification features hold promise to promote daily steps. However, results regarding the effectiveness of this type of intervention are heterogeneous and not yet confirmed in real-life contexts.

Objective

This study aims to examine the effectiveness of a gamified intervention and its potential moderators in a large sample using real-world data. Specifically, we tested (1) whether a gamified intervention enhanced daily steps during the intervention and follow-up periods compared to baseline, (2) whether this enhancement was higher in participants in the intervention than in nonparticipants, and (3) what participant characteristics or intervention parameters moderated the effect of the program.

Methods

Data from 4819 individuals who registered for a mobile health Kiplin program between 2019 and 2022 were retrospectively analyzed. In this intervention, participants could take part in one or several games in which their daily step count was tracked, allowing individuals to play with their overall activity. Nonparticipants were people who registered for the program but did not take part in the intervention and were considered as a control group. Daily step counts were measured via accelerometers embedded in either commercial wearables or smartphones of the participants. Exposure to the intervention, the intervention content, and participants’ characteristics were included in multilevel models to test the study objectives.

Results

Participants in the intervention group demonstrated a significantly greater increase in mean daily steps from baseline than nonparticipants (P<.001). However, intervention effectiveness depended on participants’ initial physical activity. The daily steps of participants with <7500 baseline daily steps significantly improved from baseline both during the Kiplin intervention (+3291 daily steps) and the follow-up period (+945 daily steps), whereas participants with a higher baseline had no improvement or significant decreases in daily steps after the intervention. Age (P<.001) and exposure (P<.001) positively moderated the intervention effect.

Conclusions

In real-world settings and among a large sample, the Kiplin intervention was significantly effective in increasing the daily steps of participants from baseline during intervention and follow-up periods compared to nonparticipants. Interestingly, responses to the intervention differed based on participants’ initial steps, with the existence of a plateau effect. Drawing on the insights of self-determination theory, we can assume that the effect of gamification could depend of the initial motivation and activity of participants.
Nurses’ and Nursing Assistants’ Experiences With Teleconsultation in Small Rural Long-Term Care Facilities: Semistructured Interview Pilot Study (Preprint)
Authors: Nabelsi Veronique , Leclerc Marie Chantal , Plouffe Véronique
Published: August 2024

BACKGROUND

In Quebec, the shortage of nurses during night shifts compromises the safety and quality of resident care, particularly in small residential and long-term care centers (“Centres d’hébergement et de soins de longue durée”; CHSLDs) located in rural areas. The need to ensure the continuous presence of nurses 24 hours a day in CHSLDs has become more pressing, forcing some facilities to implement exceptional measures such as on-call telephone services to ensure access to a nurse. In light of these challenging circumstances, the Direction nationale des soins et des services infirmiers of Quebec’s Ministère de la Santé et des Services sociaux has rolled out a teleconsultation pilot project.

OBJECTIVE

This study aims to explore nurses’ and nursing assistants’ experience of integrating teleconsultation during night shifts in rural CHSLDs with ≤50 residents.

METHODS

The 6-month pilot project was rolled out sequentially in 3 rural CHSLDs located in 2 administrative regions of Quebec between July 2022 and March 2023. A total of 18 semistructured interviews were conducted with 9 nurses and nursing assistants between February and July 2023.

RESULTS

Participants’ experiences revealed that teleconsultation provided significant added value by improving clinical, administrative, and organizational practices. Some practices remained unchanged, indicating stable workflows. Workflow optimization through an expanded scope of practice ensured efficient and safe continuity of care. Enhanced collaboration between nurses and nursing assistants led to improved care coordination and communication. The leadership played a significant role in clarifying professionals’ roles and in supporting effective adaptation to teleconsultation.

CONCLUSIONS

This pilot project represents a significant step forward in improving care for CHSLD residents in Quebec. Teleconsultation not only makes it possible to overcome recruitment challenges and ensure the continuous presence of nurses during night shifts but also optimizes professional practices while ensuring the safety and quality of care provided to residents.

The Joker Unmasked: A Literary Psychoanalytic Study
Authors: Mashhor Ahmed , Abdulkader Wafaa
Published: August 2024

Psychoanalysis primarily concerns itself with literature through the representation of the conscious and unconscious minds of characters within storylines. Sigmund Freud’s theories are often reflected in literary works, using concepts such as the pleasure principle associated with the id, the reality principle linked to the ego, castration anxiety, and defense mechanisms. Other literary theories, like reader-response theory, focus on how texts are read and interpreted by readers. Norman N. Holland suggests that understanding a literary work involves not only reading the text but also considering the author’s biography, if known, to grasp how they create their masterpieces. Literary psychoanalysis explores the psychological and emotional aspects the author embeds in their works. Even though many authors are remarkably discreet about their past, their experiences may surface through recurring themes or phrases in their writings. Joker is a film released in 2019, directed by Todd Phillips and starring Joaquin Phoenix, who won the Academy Award for Best Actor for his role. This paper conducts a psychoanalytic study of the character Joker, whose real name is Arthur Fleck. Arthur is a stand-up comedian aspiring to be the world’s most famous comedian, despite suffering from a medical condition that causes sudden and uncontrollable laughter, compounded by traumatic events in his childhood.

SHARIA LAW AND COMMUNITY RESPONSE TO ROHINGYA REFUGEES IN ACEH
Authors: Thaib Suraiya Ismail , Bin Ibrahim Muhammad , Sufi Nurkhalis Muhammad , Abu Bakar Nurlaila , Long Ahmad Sunawari
Published: August 2024

In Aceh, the implementation of Sharia law plays a significant role not only in social and religious regulation but also in responses to humanitarian issues, such as the case of Rohingya refugees. This study aims to discuss how Sharia law influences the perceptions and actions of the Acehnese community towards Rohingya refugees. The study employs a literature review as the primary approach to gather and analyze existing data. Data were collected through systematic searches in prominent academic databases, online archives, and digital libraries. The search focused on reputable journals, books, government and NGO reports, as well as relevant news articles pertaining to this area of study. The findings of this study indicate that the implementation of Sharia law in Aceh significantly influences the community's response to the arrival of Rohingya refugees. Sharia law in Aceh functions not only as a legal framework but also as a social ethos that shapes humanitarian actions towards the refugees. Sharia law has reinforced humanitarian and solidarity values within the community, as evidenced by the warm reception given to the refugees. However, the study also finds that economic and political factors can modify and even diminish these positive responses over time. The study concludes that in the context of Rohingya refugees, while Sharia law plays a role in shaping positive social norms and behaviors among the Acehnese community, it sometimes fails to adapt or is insufficiently responsive to changing economic and political pressures. These pressures can alter community perceptions and responses to refugees in the long term. Therefore, the study concludes that the complex dynamics between Sharia law and socio-economic conditions in the context of refugees are critical aspects that policymakers and humanitarian practitioners need to address.

Authors: Hanna Rana E. , Smith Logan R. , Mhaskar Rahul , Hanna Karim
Published: August 2024

Background and Objectives: Artificial intelligence (AI), such as ChatGPT and Bard, has gained popularity as a tool in medical education. The use of AI in family medicine has not yet been assessed. The objective of this study is to compare the performance of three large language models (LLMs; ChatGPT 3.5, ChatGPT 4.0, and Google Bard) on the family medicine in-training exam (ITE).
Methods: The 193 multiple-choice questions of the 2022 ITE, written by the American Board of Family Medicine, were inputted in ChatGPT 3.5, ChatGPT 4.0, and Bard. The LLMs’ performance was then scored and scaled.
Results: ChatGPT 4.0 scored 167/193 (86.5%) with a scaled score of 730 out of 800. According to the Bayesian score predictor, ChatGPT 4.0 has a 100% chance of passing the family medicine board exam. ChatGPT 3.5 scored 66.3%, translating to a scaled score of 400 and an 88% chance of passing the family medicine board exam. Bard scored 64.2%, with a scaled score of 380 and an 85% chance of passing the boards. Compared to the national average of postgraduate year 3 residents, only ChatGPT 4.0 surpassed the residents’ mean of 68.4%.
Conclusions: ChatGPT 4.0 was the only LLM that outperformed the family medicine postgraduate year 3 residents’ national averages on the 2022 ITE, providing robust explanations and demonstrating its potential use in delivering background information on common medical concepts that appear on board exams.
Learning Networks: How Family Medicine Departments Are Meeting the Requirement
Authors: Seehusen Dean A. , Brout Isabella , Wilson Stephen A.
Published: August 2024

Background and Objectives: In 2023, the Accreditation Council for Graduate Medical Education added participation within a “learning collaborative” or “learning network” (LN) as a requirement for family medicine residencies. The structure and scope of what makes an acceptable LN was only vaguely defined. The purpose of this study was to learn how many family medicine residencies associated with departments already belong to LNs, the purpose and funding of these existing LNs, and barriers to entering LNs.
Methods: An online survey was sent to family medicine department chairs through a Council of Academic Family Medicine Educational Research Alliance omnibus study from August to September 2023. Survey questions explored the purpose, structure, and funding of LNs that associated residency programs already belonged to as well as the chairs’ beliefs and knowledge about LNs.
Results: Of the 227 chairs, 119 completed the survey (50.2%). About 53% reported that their department was part of an LN, with more than one-third belonging for 5 years or less; 47% had a low understanding of what an LN is; and 71% had little to no concern that collaborating in an LN would negatively affect residency recruitment. The purpose of most LNs was a mix of research, education, and clinical activities. Faculty’s lack of knowledge about LNs and lack of time were the top barriers identified to joining an LN. Funding was varied, and departmental funding was positively associated with administrative control of the LN.
Conclusions: About half of the residency programs associated with family medicine departments already belong to LNs. Wide variation among existing LNs may lead to significantly disparate outcomes for residents and residencies as they navigate this new requirement.
Emergency Department Versus Primary Care Use: A Patient Perspective
Authors: Wu Natasha , Woloski Jason R.
Published: August 2024

Introduction: When faced with an acute illness, patients routinely make the decision of whether to present to their primary care physician (PCP) or the emergency department (ED). While the ED is known to be a high-cost component of the health care system, many ED visits include nonurgent ailments that could easily be treated within the medical home/primary care office. Particularly for patients who have an established PCP, the factors driving a preference for ED use remain poorly understood. The purpose of this study was to better understand patient motivation for visiting the ED rather than the PCP office.
Methods: This observational study aimed to take a qualitative look at the patient population using a health system ED in the city of Wilkes Barre, PA, from December 2021 to March 2022. We conducted 30 interviews of patients who recently visited the ED and analyzed the responses for recurring themes.
Results: Major themes included the benefit of the PCP-patient relationship, patients’ preference for multiple sources of medical guidance, patients’ subjectively justifying their symptoms as emergent, seeking emergent care despite perception of higher cost, and factoring in time spent at a health care facility waiting for answers. 
Conclusions: This study contributes to further understanding of the values that drive ED use by using patient voice as a powerful tool to understand communities and local trends, which will allow health care systems to adapt and personalize protocols to their specific population.

Authors: Hong Soon-Min
Published: August 2024

In this second part of series report on evidence-based dentistry, the level of evidence and the methods for critical appraisal arediscussed. The epidemiologic studies, namely clinical studies have some bias per se, and the degree of bias is somewhatpredetermined by the study design. The level of evidence can be defined as the reliability of the clinical study and it is dependenton the degree of bias. Thus, it is important to determine the type of the study and to understand its structure before criticallyappraising them. Systematic reviews of primary studies, randomized controlled trials, nonrandomized clinical trials, cohort studies,case-control studies, and case reports / series constitute the clinical studies and the level of evidence follows the order of thestudies listed above. Critical appraisal is the most important procedure in evidence-based dentistry. It is done to determine thecredibility of research papers and their usefulness in the clinician s own practice. Critical appraisal is consisted of multiplequestions that are helpful for evaluating validity and usefulness of the studies concerning therapy, diagnosis, prognosis, andcausation.

Authors: Son J-H , Kim Y-H , Kook Y-A
Published: August 2024

The aim of this study was to investigate the relationship between the mandibular antegonial notch and the mandibular morphology, and the curve of Spee in anteroposterior skeletal relationship. Pre-treatment lateral cephalograms were obtained from 80(male 34, female 46) adult orthodontic patients and the samples were classified into 3 categories by ANB angle(0°≤ANB< 4° Class I, 4°≤ANB Class II, ANB< 0° Class III). The curve of Spee was measured directly from the pre-treatment mandibular study cast of each patient included in this study. Pearson correlation coefficient test and multiple regression analysis in each group revealed the following results; 1. Antegonial notch depth was positively correlated with hoth lower anterior facial height(ANS-Me) in skeletal Class I, II and III groups and Id-Me height in skeletal Class I and II groups. 2. A statistically significant negative correlation was found between the depth of the antegonial notch and the curve of Spee in the Class III group. 3. Significant relationship was not found between the antegonial notch depth and any of the other cephalometric variables such as mandibular body length(Go-Gn) and ramus height(Co-Go). As antegonial notch depth increased, more vertical growth of the mandible was observed. Antegonial notch can be used as a predictor of vertical mandibular growth in the diagnosis and treatment planning of malocclusion.

Published: August 2024

The risk of temporomandibular joint disorder (TMD) can be increased during dental treatment due to excessive mouth opening and change of occlusion. The aim of this study is to find the relationship between dental treatment and TMD in the patients who developed TMD after dental treatment. The subjects of this study were 21 patients, who developed TMD after dental treatment and were treated with active TMD therapy in Seoul National University Bundang Hospital from June 2003 to February 2007. The subjects were examined with preceding dental treatment, symptom, diagnosis, treatment method of TMD and prognosis of TMD. The obtained results were as follows. 1. Preceding dental treatments were : Implant treatment, 14 cases ; Tooth extraction, 3 cases and others. 2. TMD symptoms were : pain on TMJ, 12cases : Sound on TMJ, 3cases ; Mouth opening limitation, Headache and others. 3. Diagnoses of TMD were : Synovitis and/or capsulitis, 10 cases ; 8 cases of Internal derangement and others. 4. Most TMD were treated by stabilization splint. 5. Prognoses of TMD were : Improvement, 6cases ; sustained 11 cases. In conclusion, the risk of TMD is increased during implant treatment. Prognoses of TMD after dental treatment were bad. It might be that these patients were non-cooperative and have distrust of dental treatment. Because the overloading on TMJ is possible in dental treatment of patients with underlying TMD, prior explanation and knowledge TMJ treatment are very important in these cases.

Esthetic treatment of Dentinogenesis imperfecta
Authors: Jin Myeong-Uk
Published: August 2024

Dentinogenesis imperfecta is one of the most common autosomal dominant traits experienced in humans. It generally affects both the deciduous and permanent dentitions. There are 3 forms of dentinogenesis imperfecta that have been classified into type I(osteogenesis imperfecta associated), type II(hereditary opalescent dentin), and type III(Brandywine isolate opalescent dentin).1,2 The prevalence for all types of dentinogenesis imperfecta is approximately 1 per 8000 subjects. Early diagnosis and treatment are therefore, fundamental, aiming at obtaining a favourable prognosis since late intervention makes treatment more complex. This clinical report describes a treatment solution to the problems encountered by a dentinogenesis imperfecta patient with minimally invasive techniques.

Purpose : The purpose of this study is to investigate the effects of Simvastain, which is HMG-CoA reductase inhibitor, on proliferation and differentiation of osteoblast. Materials & Methods : Twenty-four cell culture plates containing essential medium were seeded with UMR-106 cell lines, at density of 5 x 104 cells per plate. Each plates were incubated with 5% CO2incubator 37°C. Starting from 2 days after incubation, cell culture medias were replaced with Osteogenesis induction media every 2 days, for 12 days. In some plates, 0.01, 0.1, 1, 10, 100muM of Simvastatin were added with Osteogenesis induction media, and classified as "test group". Those not added with Simvastatin were classified as "control group". Results : 1. When Alrizarin Red staining was observed with naked eye, control group showed normal deep red color, but test group show rapid decrease of red color as Simvastatin concentration increased more than 0.1muM. 2, When observed with microscope, compared to control group, amount of osteo matrix stained with Alrizarin Red decreased rapidly in Simvastatin concentration more than 0.1muM. 3. In optical density analysis, regarding control group as a basis, mineral deposition decreased rapidly when Simvastatin concentration increased more than 0.1muM. 4. In flow cytometry analysis, survival rate of UMR-106 cell showed no changes in both control group and test group. Conclusion : From the above results, we were able to identify that Simvastatin inhibited osteogenesis without effecting survival or cell number of osteoblasts.

Purpose : Anterior region is crucial area for esthetic implant restoration. However, the alveolar process undergoes atrophy after removal of teeth and creates unfavorable situation for implant installation. The knowledge of the thickness of alveolar bone is required to estimate and expect the bone resorption after extraction. The aim of this study is to measure facial, palatal and faciopalatal bone thickness on maxillary anterior teeth. Methods : Facial, palatal, and faciopalatal bone thickness were measured on the computed tomography (CT) images from 57 patients, using an image analyzer program (Ondemand3D(R), Cybermed, Seoul, Korea). Results : The thickness of facial bone in incisors, lateral incisors and canines were less than 1 mm. The thickness of facial bone increased from anterior to posterior region and the thickness of palatal bone increased from posterior to anterior region. Conclusion : The measurement can be used for planning implant surgery before extraction. CT has are clinically useful in the evaluation of thickness of alveolar bone.

Purpose : Schulte introduced immediate implant cases in 1970s, since then many patients have been treated by immediate implants. The aim of this study was to evaluate the cumulative survival rate of immediate implant and to analyze various factors associated with survival of immediate implant in a 8-year period retrospectively. Materials and methods : From May, 2000 to October, 2007, 77 implants were placed in 63 patients immediately after tooth extraction at Department of Periodontology, Yonsei University Hospital. The implant survival rate was analyzed using a life-table analysis. After delivery of prosthesis, along 1 year of observation period, all implants were evaluated clinically and radiographically. Results : Among 77 implants, 59 were placed in maxilla and 18 in mandible. The most common site of the implantation was Mx anterior (65%). The overall survival rate was 94.8% over a mean follow-up period of 44.2pm21 months and the 8-year cumulative survival rate was 94.6%. Failure occurred in 4 implants, all of which were due to early failures. None of the following factors were significantly associated with the survival of immediate implants: advanced surgical technique including bone graft and guided bone regeneration, the types of implants, causes of tooth loss, and types of prosthesis. Conclusion : On the basis of 8-year life time analysis, immediate implant placement can be considered a safe and predictable treatment mordality.

This article presents a modified palatal pedicled incision design in anterior segmental maxillary osteotomy. This method included the circumcrevicular incisions and two vertical relaxing incisions. Then, it is different from the Couper's method with vestibular horizontal incision and other anterior segmental osteotomy techniques. The main advantages of this method are an improved visibility of surgical field and favorable preservation of palatal pedicle. A patient who had been operated by anterior segmental maxillary and mandibular osteotomy without pre operative orthodontic treatment was analyzed for advantages and complications during the intraoperative and early post operative period. There are no specific major complications such as infection, gingival recession and dehiscence. And the patient had a pleasing esthetic facial appearance.

Objectives : The study explored perceptional gap of dentists and their employees between expectation and satisfaction. Methods : For analysis, the study surveyed 407 employees and 91 dentists on their expectation and satisfaction depending on expectation. Results : When the satisfaction on a question was lower than expectation; the rate of sufficiency was below 100%, it is necessary to improve on the question. Contrarily when the satisfaction on a question was higher than expectation; the rate of sufficiency was upper 100%, it is necessary to continuously support the question. The most of satisfaction of employees on their dentists and their organization were lower than employees's expectation of those. The most of satisfaction of dentists on their own and employees were lower than dentists's expectation of those as similar as employees cases, It means that all of questions need to improve continuously. Conclusions : The issues for prior decision to change these phenomena are 1) improvement of communication each other, 2) recovery of credence each other, and 3) leadership style change from authoritarian to consideration.
Clinical application and classification of bone graft material according to component

I classified the bone graft material according to the component. Most bone graft material is composed of inorganic and organic constituent. Organic component such DBM is associated with osteoinduction. Inorganic components such as hydroxyapatite, beta-TCP, calcium sulfate, bioactive glass, polymer are associated with osteoconduction. Autogenous bone graft is ideal material. We can select any biocompatible material for the restoration of small filling defect with intact bony wall. However, we should select first osteogenetic and osteoinductive material to regenerate the viable bone tissue.

Orthodontic treatment for middle-aged patients has become more commonplace with various reasons including improved socioeconomic status. Understanding of oral status and treatment modalities of middle-aged patients is mandatory for accurate diagnosis and proper treatment planning. This study investigated 100 consecutive patients aged 40s and 50s and 100 aged 20s who had been examined and diagnosed at the Department of Orthodontics, Chonnam National University Dental Hospital. The results were obtained as follows; 1. Gender distribution showed female outnumbered male patients in young-aged adult patients, but middle-aged patients showed similar male and female distribution. 2. The major concern seeking orthodontic treatment was esthetics not only in young-aged but also in middle-aged adult patients, and a number of middle-aged patients were concerned about oral health as well. 3. Considerable number of middle-aged patients were referred by other dental specialties while young-aged adult patients were more self-motivated for orthodontic treatment. 4. Middle-aged adult patients had more missing teeth and periodontal disease than young-aged adults. 5. The most frequently-observed problem was dental spacing in middle-aged patients while dental crowding in young-aged adult patients. Middle-aged patients showed higher prevalence of deep overbite and overjet while most of young-aged adults presented opposite direction of problem in overbite and overjet. 6. Limited orthodontic treatment was required rather than comprehensive treatment in middle-aged patients, and the most common tooth moving area was anterior part of dentition in case of limited treatment. Need of interdisciplinary therapy with other dental specialties was more common in middle-aged patients. 7. Intervention of specific technique such as invisible TP, passive bracketing, passive wire bonding, and lingual orthodontics was more required in middle-aged patients. Considering that middle-aged patients have different characteristics than young-aged adults, the results of the present study suggest that different treatment modalities are required in middle-aged orthodontic patients in order to manage them properly and efficiently.
