Authors: Wahyuningsih Sri , Ni'mah Isna Silfiya
Published: May 2023

Self-confidence plays a pivotal role in public speaking, especially in English. Therefore, building students’ self-confidence is needed by using media including YouTube. The present study aims to elaborate on the role of YouTube in developing students’ self-confidence in English public speaking viewed from the student’s perspective. Further, some strategies used in developing students’ self-confidence are discussed. Using a qualitative method, the data of this study were gathered through a semi-structured interview with six students from the English Education Department of an Indonesian Islamic university. The findings reveal that most students have positive responses towards the use of YouTube as a medium to develop their self-confidence in English public speaking. In addition, they reported that YouTube plays a very crucial role in the development of their confidence in English public speaking. Importantly, they can comprehend the material more quickly, and develop their interest and motivation to learn. Finally, this study promotes the need for socialization from educational institutions in the development of English public speaking and the need to integrate the content of English public speaking with media and technology to enhance students’ learning success.

Authors: Maharani Feni , Fithriani Rahmah
Published: May 2023

This study examines pre-service teachers' experience, especially on challenges they face through transformative learning. Qualitative descriptive research was utilized as a research methodology to explore the teachers’ experience during teaching practicum. Five seventh semester students of English education department were invited to be the participants of the study. The data were collected through reflective notes and in-depth interviews and then analyzed thematically. The results show that the pre-service teachers confront several obstacles throughout their teaching practicum. According to the data, the obstacles pre-service experienced were a Tension between vision and reality, teaching practicum, which is accompanied by class lectures, classroom management, and lack of supervision. The obstacles are then explored via transformational learning, which enables teachers to overcome them, particularly in classroom management, enhancing their capacity to choose teaching techniques depending on the needs and skills of students. This study is hoped the difficulties during teaching practicum faced by pre-service teachers can be reduced so that the objectives of teaching practicum can be achieved properly.

Published: May 2023

The present work describes numerical and experimental investigation of the heat transfer characteristics in a plate-fin, having built-in piezoelectric actuator mounted on the base plate (substrate). The geometrical configuration considered in the present work is representative of a single element of the plate-fin and triple fins. Air is taken as the working fluid. A performance data for a single rectangular fin and triple fins are provided for different frequency levels (5, 30 and50HZ) , different input power (5,10,20,30,40 and 50W) and different inlet velocity (0.5, 1, 2, 3, 4, 5 and 6m/s) for the single rectangular fin and triple fins with and without oscillation. The investigation was also performed with different geometrical fin heights ( 50mm and 35mm) and distance between the fins (3mm and 6mm). It is observed that the heat transfer increases with the increase in the frequency and Reynolds number. It is further observed that triple fins with (height=50mm and distance between the fins=3mm) gives better enhancement as compared to othercases, The study shows that the piezoelectric actuator when mounted on the rectangular fins gives great promise for enhancing the heat transfer rate

Exploring the Dimensions of Responsible Research Systems and Cultures: A Scoping Review
Authors: Field Sarahanne Miranda , Thompson Jacqueline , de Rijcke Sarah , Penders Bart , Munafo Marcus Robert
Published: May 2023

The responsible conduct of research is foundational to the production of valid and trustworthy research. Despite this, our grasp of what dimensions responsible research (RR) might contain – and how it differs across disciplines (i.e., how it is conceptualized and operationalized) – is tenuous. Moreover, many initiatives related to developing and maintaining RR are developed within disciplinary and institutional silos which naturally limits the benefits that RR practice can have. To this end, we are working to develop a better understanding of how RR is conceived and realized, both across disciplines, and across institutions in Europe. The first step in doing this is to scope existing knowledge on the topic, of which this scoping review is a part. We searched several electronic databases for relevant published and grey literature. An initial sample of 715 articles was identified, with 75 articles included in the final sample for qualitative analysis. We find several dimensions of RR that are underemphasized or are excluded from the well-established World Conferences on Research Integrity Singapore Statement on Research Integrity (WCRI) and explore facets of these dimensions that find special relevance in a range of research disciplines.

Universal Existence
Authors: Petrakis Sócrates Georges
Published: May 2023

Existence is the most fundamental and broad concept that can be used for definitions. Existences can be perceived as presences that change in space through interactions, attesting to the temporal dimension. The Universe, which exists and contains everything, can be considered unique because it has nothing around it with which to interact; therefore, its current existence, change or entropy variation, represented by an expansion, is defined by the interactions between its components, tending to reach a state of complete uniformity (without energy concentrations). Since universal evolution can continue if there is mass (concentrated energy) and space in between, the most extreme states of expansion and contraction are modeled, revealing an existential continuity in perpetual time. To clarify this perspective, the Standard Model, which considers 3D Space, is supplemented by the concepts of rest energy and vanishing dimensions. After considering and interweaving data and principles already presented in other studies, the addition or differentiation of this study is to present a cause for the beginning of the current expansion of the Universe and to improve the understanding of the process of existential evolution.

Cultural Threat Perceptions Predict Violent Extremism via Need for Cognitive Closure
Authors: Obaidi Milan
Published: May 2023

Understanding the psychological processes that drive violent extremism is a pressing global issue. Across six studies, we demonstrate that perceived cultural threats lead to violent extremism because they increase people’s need for cognitive closure (NFC). In general population samples (from Denmark, Afghanistan, Pakistan, France, and an international sample) and a sample of former Mujahideen in Afghanistan, single-level and multi-level mediation analyses revealed that NFC mediated the association between perceived cultural threats and violent extremist outcomes. Further, in comparisons between the sample of former Afghan Mujahideen and the general population sample from Afghanistan following the known-group paradigm, the former Mujahideen scored significantly higher on cultural threat, NFC, and violent extremist outcomes. Moreover, the proposed model successfully differentiated former Afghan Mujahideen participants from the general Afghan participants. Next, two pre-registered experiments provided causal support for the model. Experimentally manipulating the predictor (cultural threat) in Pakistan led to higher scores on the mediator (NFC) and dependent variables (violent extremist outcomes). Finally, an experiment conducted in France demonstrated the causal effect of the mediator (NFC) on violent extremist outcomes. Two internal meta-analyses using state-of-the-art methods (i.e., meta-analytic structural equation modelling and pooled indirect effects analyses) further demonstrated the robustness of our results across the different extremist outcomes, designs, populations, and settings. Cultural threat perceptions seem to drive violent extremism by eliciting a need for cognitive closure.
Low Overlap and High Heterogeneity Across Common Measures of Eating Disorder Pathology: A Content Analysis
Authors: Christensen Pacella Kara Alise , Wossen Lidia , Hagan Kelsey E.
Published: May 2023

Background: This study evaluated symptoms assessed in common measures of eating disorder pathology and tested overlap to evaluate the extent to which measures may be interchangeable. Methods: Six measures were included: Bulimia Test-Revised (Thelen et al., 1991), Eating Attitudes Test-26 (Garner et al., 1982), Eating Disorder Diagnostic Scale (Stice et al., 2004), Eating Disorders Examination Questionnaire (Fairburn & Beglin, 1994), Eating Pathology Symptoms Inventory (Forbush et al., 2013), and Questionnaire for Eating Disorder Diagnoses (Mintz et al., 1997). Content overlap was quantitatively estimated using the Jaccard Index. Results: Mean overlap was low (.195), likely due to the wide range of symptoms (87) assessed. The mean overlap of each measure with all others was .117 - .267, and the overlap among individual measures was .083 - .382. Conclusions: Implications of low overlap among measures include variable characterization of eating disorder phenotypes and the risk for lower generalizability of findings due to measurement variability.
Effects of healthy ageing and bilingualism on attention networks
Authors: Markiewicz Roksana , Rahman Foyzul , Fernandes Eunice G. , Limachya Rupali , Wetterlin Allison , Wheeldon Linda , Segaert Katrien
Published: May 2023

Both ageing and bilingualism can have positive as well as adverse cognitive effects. We investigated their combined impact on subcomponents of attention. We used the Attention Network Task to examine alerting, orienting, executive control and task-switching costs. Group comparisons revealed age-related declines for alerting alongside benefits for executive control, for mono- and bilinguals alike. For orienting, age-related decline was more pronounced for bilinguals than monolinguals. Task-switching was unaffected by age or language group. Within bilinguals, we found limited impact of individual differences in L2 proficiency, language switching or mixing: proficiency improves orienting and decreases switch costs, for young and older bilinguals alike; but no other individual differences effects were found. Thus, attention is a multi-faceted network, with clear adverse (alerting) and protective (executive control) ageing effects. We found these to be largely similar for mono- and bilinguals, with variability within bilinguals having only limited impact.

Having raised the question, it has been analyzed based on the established principles of feminist theory. There is a depiction of the tendency developed in men to regard women as instruments of pleasure. In the drama, the tyranny of women has developed since Krishna destroyed the motherhood of the young woman. Young women, brides, eloquent and mothers of Bhoti have endured mental torture due to their husband's neglect and impotence. Here, the girl and the bride seem to express their anger towards the husband's behavior. Realizing that her motherhood has been murdered, young women abandon their husbands and start to awaken a sense of rebellion in women. Analyzing the play on the basis of subtitles such as introduction, method of study, feminist theory, analysis of Masan drama under the heading of women's consciousness in Masan drama. It has been concluded that the awareness of rebellion among women is becoming stronger.
Democratic Transition of Nepal-2006: A Theoretical Sociological Analysis
Authors: Subedi Tek Nath
Published: May 2023

Democracy approximates a politically equal situation to all human subjects. People’s voice for democracy and increasing number of countries adopting a democratic regime indicate democracy’s endorsement of the notion ‘people as sovereign’. Often said, each People’s Movement is inclined to one’s right to freedom, equality and justice. Thus, democracy is deliberately inserted into any of the contemporary debates ranging from a peaceful deal to any social movement and war, be it the external type of Independence Movement, or the internal type of social, cultural, economic and political riots, protest movements or great revolutions including the French Revolution and others. The late-twentieth and early twenty-first century witnessed communist regimes’ gradual greet to democracy, and a situation occurred as if democracy was an undisputed form of regime. In 2006, a collective campaign of people throughout the country came to the street making alliance with the civil society organizations, previously underground Maoist party and other mainstream political parties to protest the royal takeover and bring democracy back into practice. The movement was culminated with bringing a huge transition – Nepal’s Democratic Transition-2006 – which this paper attempts to theorize. By giving special reference to the Game Theory of Daron Acemoglu and James A. Robinson, this paper verifies the role of micro and macro components as equally and strategically active for enabling the democratic transition of a nation.

The way students who want to become teachers represent their mathematical reasoning when they solve mathematical problems—using case studies and qualitative techniques. Data were gathered from the vignette results of student work. They are using snowball sampling for subject selection. Three third-semester mathematics education program participants served as the study's research subjects—ways for gathering data, such as interviewing and recording. Three steps of the analysis were completed: presentation of data, elaboration of conclusions and verification. As a consequence of meeting all markers of mathematical thinking representation, the S1 and S2 subjects with high and moderate academic talents had good mathematical thinking representation abilities. Because S3 students with limited intellectual skills cannot still represent mathematical ideas.
“As a rule, I don’t have sex on the first date”: Gender and age differences in motivations, perceptions, and experiences on Tinder
Authors: Roca-Cuberes Carles , Roig-Mora Arnau , Álvarez-Cueva Priscila
Published: May 2023

This research explores the impact that gender and age have on motivations, experiences, and perceptions regarding the use of Tinder. Based on an inductive analysis of 37 semi-structured interviews with heterosexual Tinder users, we specifically examine gender and age differences in motivations, match selection, and communication management on this mobile dating app. The findings show that age differences have a more significant effect on motivations than gender differences do, whereby older adults use the app to find a stable partner, and young adults use it for sex. Women are more selective when picking matches than men, and when they make these selections, they pay special attention to male attributes that are typically associated with maintaining stable relationships. In contrast, men tend to focus almost exclusively on physical appearance. Between the match and the first date, users need to deal with a considerable volume of communication, which involves the use of different communication media in a series of consecutive stages, toward which matches normatively orient themselves. This transition to new media and stages, in which men tend to take the initiative and women assume the sanctioning role, marks a kind of incremental passage to intimacy. We conclude that, in their courting conduct, Tinder users perform conventional gender scripts that are typical of the heteronormative model of intimate relationships.

Authors: Da Cruz Carvalho Leandro Paim
Published: May 2023

Diabetes tipo (DT1) é uma doença metabólica modulada por fatores de risco como composição corporal (CC), que pode ser analisada pela mensuração de compartimentos corporais, percentual de gordura corporal (%GC), massa gorda (MG) e massa magra (MM). O Objetivo foi analisar fórmulas para mulheres com DT1 usando absormetria radiológica de dupla energia (DEXA) como padrão ouro. 3 mulheres diabéticas tipo 1 participaram de um estudo experimental. Foram submetidas a medidas antropométricas (peso, altura, perímetros, e dobras cutâneas) e DEXA. Cinco fórmulas foram utilizadas para comparar os resultados utilizando índice de massa corporal (IMC), dobras cutâneas (DC) e perímetros (P) como valores principais. Teste de Friedman foi aplicado comparando valores de %GC, MG e MM. Como resultados sete equações apresentaram diferenças com valores do DEXA (p=0.002; F=14.05). Conclui-se que apesar de diferenças visuais, métodos usando IMC, DC e P podem ser uma forma de avaliação prática, de baixa custo para mulheres com DT1, em relação a variáveis de composição corporal obtidos pelo DEXA.
DOES PHYSICAL LITERACY PREDICT ACADEMIC ACHIEVEMENT IN ADOLESCENT STUDENTS?
Authors: Chagas Daniel , Marinho Blena , Awata Raphael
Published: May 2023

There is an assumption that fostering PL in young students can enhance performance and achievement in other areas of the curriculum. However, evidence supporting this relationship is missing. The purposes of this study were to verify whether physical literacy (PL) is correlated with academic achievement (AA) in adolescent students and whether PL predicts AA across time. A cohort study was conducted with 122 adolescents. Participants were assessed at baseline and 5 months later. PL was determined in terms of psychomotor domain (motor competence, physical activity level, musculoskeletal fitness and body composition). AA was measured at both time points and determined using writing, reading and math scores in standardized tests. Pearson correlations and regression analysis between PL and AA were performed. No significant correlations were found between PL and AA. Regression analysis revealed that PL did not predict AA across time. This study indicates that PL does not predict AA in adolescent students across time. Regardless, we encourage the promotion of PL in physical education classes and educational settings due its importance for general development of children and adolescents, including aspects of health and behaviour.

Authors: Tampubolon Kevin A.G , Pramod Sawkar V
Published: May 2023

Background: Bladder cancer is a common type of urinary system cancer in the world with high morbidity and mortality if not managed optimally. Currently, partial cystectomy has experienced a resurgence as a less morbid and oncologically effective treatment. Here, we appropriately diagnosed and surgically treated 5 patients with partial cystectomy without frozen section and reviewed the outcome of this procedure. Case presentation: The diagnosis was made based on the history of illness, physical examination, CT-Scan, and confirmed by histopathological examination. A partial cystectomy was performed in all cases, which include laparoscopic partial cystectomy. Based on histological examination, we found that 4 cases in this study were adenocarcinoma bladder and 1 case was urothelial carcinoma cells with sarcomatoid variant. Our surgical technique started with doing a cystoscopy first. We performed excision of the tumor with lateral margin 1cm around the tumor. After resection of the tumor, we closed the bladder and evaluated the capacity of the bladder, which was 200cc minimal capacity. Then we closed the bladder with the double layer technique and closed the muscle, fascia, and skin, respectively. Follow-up was performed 6 and 12 months after surgery to observe progression or recurrence of the tumor. There was no postoperative complication in our case. All of our cases had no complaints and no sign of progression, recurrence, and metastatic sign. Conclusion: A frozen section has not been proven to be mandatory in partial cystectomy and the results had no significant effect in surgical margins. A Partial cystectomy had a good result and improved the quality of patient life with preserved the bladder function.

Published: May 2023

Background: COVID-19 pandemic has caused unprecedented challenges to healthcare delivery globally. Children with cancer are a vulnerable group given their immunosuppressed state. There is paucity of data regarding the organisation of pediatric cancer care and outcomes of children with cancer who developed COVID-19 infection. We describe the organisation of care in a Pediatric Oncology unit in a tertiary care hospital in South India and describe the clinical profile and outcomes of children with cancer who were diagnosed with COVID-19 infection. Methods: This was a retrospective chart review of all children admitted to the pediatric oncology unit and diagnosed with COVID-19 infection between March 2020 and October 2020. Descriptive statistics were calculated. Results: A total of 144 children were on active chemotherapy during the study period. Of these, Nine (6.2 %) were diagnosed with COVID-19. Fever and cough were the predominant symptoms. Majority (88%) had mild symptoms. COVID-19 was positive at cancer diagnosis in 22%. PICU care was required for 33%, but for non-covid related concerns. Recovery from Covid-19 was seen in 88%. Chemotherapy administered during or after Covid-19 infection was well tolerated. Co-existent sepsis or CMV infection resulted in severe symptoms leading to mortality and this was not related to severe covid related symptomatology. Conclusions: In our study, majority of children with cancer who developed covid-19 had mild symptoms and recovered uneventfully. Chemotherapy should not be delayed in children with active cancer. The overall outcomes of pediatric oncology care during the pandemic are reassuring.

Introduction: Oral potentially malignant disorders (OPMD) have a higher risk to develop into oral cancer, which is the comments cancer in males in Sri Lanka. The covid-19 pandemic had significant ill effects on the health care systems, worldwide. Objective: To retrospectively investigate the management of OPMD patients presented to the oral medicine clinic of the University Dental Teaching Hospital Peradeniya, Sri Lanka before and during the pandemic. Methods: This was a hospital-based cross-sectional study using medical records. The pre-pandemic group included patients diagnosed with OPMD presenting between Jan 2018 - Dec 2019; the pandemic group from Jan 2020 to Dec 2021. Results: There were 321 eligible medical records. Of these, 247 belong to the pre-pandemic group and 74 in the pandemic (3:1). In the pre-pandemic group, 32% of biopsies were performed within the first week, while it was 56% in the pandemic group. We found a significant increase in the loss of follow-up in the pandemic group compared to the pre-pandemic group (p=0.01). The average delay for the 2nd visit was 27 days, for the 3rd visit it was 127 days in the pre-pandemic; and 89 and 152 days respectively in the pandemic group.Conclusions: We recommend following evidence-based practices for the management of OPMD in anticipated pandemics. Strategies to diagnose patients at home must be developed and implemented. There is a higher need for the prevention of habit-related risk factors. Biopsy at the first visit or first week is recommended. Patients should be monitored using digital technologies in the absence of physical follow-up.

Esse livro nasce de duas circunstâncias que se somaram para sua aparição. A primeira, bem dramática, deve-se à pandemia do Corona vírus, uma vez que o trabalho de campo previsto no projeto de pesquisa ficou inviabilizado. Para seguir com a dimensão empírica que compunha as estratégias metodológicas decidi entrevistar especialistas que trabalhassem com o conceito de espectatorialidade, inspirada na dinâmica da técnica Delphi. Daí surge a segunda circunstância, quando o primeiro entrevistado perguntou se eu iria publicar, o que não me havia ocorrido até então. Espero que os leitores se sintam tão provocados quanto eu para seguir no debate das questões aqui apresentadas.

Pakistan’s role as a front-line country for the US in the War on Terror has profound implications for its domestic politics and foreign policy. With a majority Pashtun population, KPK has been a target of the War on Terror because of its social setup, cultural restraints, and the faith of its population at the boundary with Afghanistan. The socio-cultural similarities and geographical proximity with Afghanistan have made it important for Al-Qaeda militants. The War on Terror in KPK had negative political, economic,and social repercussions for the area and as a result, created hatred in the Pashtuns. This paper is an attempt to analyze the elements which made the Pashtuns of this place vulnerable to militancy. It explores the political, economic, and social implications of the War on Terror for KPK and its Pashtun populace specifically.
Pakistan's Foreign Policy in the Context of Z.A Bhutto: Towards Nonalignment

US withdrawal of military support during 1965, 1971, and 1975 led to a widespread perception in Pakistan that the US was an unreliable ally and had betrayed Pakistan. Initially, their relations were cordial but later on, this alliance became weaker especially during Zulfiqar Ali Bhutto's government. Bhutto after taking charge of the government reshaped Pakistan's internal and external politics. He adopted new dimensions regarding Pakistan's Foreign policy goals. He tried to free Pakistan from US influence and dependence and desired Pakistan to acquire nuclear capabilities. The paper aims to throw light on the factors that led to the drift in Pak-US relations. The findings of the study concluded that Bhutto adopted socialist policies and promoted friendly relations with socialist countries like the Soviet Union and the Peoples' Republic of China. All these steps were against the US interests. Pakistan also abandoned SEATO and CENTO pacts during this phase.

Fashion Viral Solo merupakan salah satu distributor perlengkapan fashion di Surakarta yang belum memanfaatkan data yang dimiliki untuk melakukan segmentasi dan mengelompokkan pelanggan berdasarkan kemiripannya. Segmentasi adalah proses untuk mencari tahu karakteristik dari pelanggan berdasarkan kesamaan tertentu, sehingga memudahkan pengumpulan informasi tentang pelanggan yang memberikan profit bagi perusahaan. Segmentasi menjadi salah satu strategi untuk menghadapi persaingan usaha, untuk mempertahankan pelanggan, dan untuk membantu manajemen dalam menyusun strategi promosi untuk meningkatkan penjualan. Tujuan dari penelitian ini adalah melakukan segmentasi pelanggan yang pernah bertransaksi di Fashion Viral Solo berdasarkan karakteristiknya. Pada penelitian ini, peneliti menggunakan algoritma K-Means untuk melakukan clustering dan penerapan metode Recency, Frequency dan Monetary. K-Means adalah algoritma sederhana, mudah diimplementasikan, tidak lambat, mudah disesuaikan, dan sering digunakan dalam proses data mining khususnya clustering. Nilai atribut Recency menunjukkan waktu terakhir transaksi, Frequency menunjukkan jumlah transaksi, dan Monetary menunjukkan total nominal transaksi. Dengan menggunakan K-Means dan metode Recency, Frequency dan Monetary, peneliti dapat melakukan segmentasi pelanggan Fashion Viral Solo. Dari penelitian ini, diperoleh hasil 2 cluster pelanggan. Cluster 1 dengan jumlah anggota terbanyak, yakni 343 pelanggan dan cluster 2 dengan jumlah anggota 8 pelanggan. Untuk menentukan jumlah cluster yang paling optimal, peneliti menggunakan metode Silhouette Scores dan diperoleh hasil jika membagi pelanggan menjadi 2 cluster adalah yang paling optimal.
Direkt-demokratisch oder doch repräsentativ: Welche Entscheidungsmodi präferieren Bürger*innen? (online first)
Authors: Vetter Angelika , Brettschneider Frank
Published: May 2023

Demokratische Entscheidungen werden in repräsentativen Demokratien durch die von den Bürger*innen auf Zeit gewählten Repräsentant*innen getroffen. Alternativ gibt es in allen Bundesländern aber auch die Möglichkeit, dass Bürger*innen über Sachfragen auf Länder- oder kommunaler Ebene direkt abstimmen (Bürger- oder Volksentscheide). Wir untersuchen mit Hilfe eines neuen Mess-Ansatzes auf Basis einer repräsentativen Umfrage, welche demokratischen Entscheidungsmodi von den Bürger*innen auf verschiedenen Ebenen des politischen Systems präferiert werden. Berücksichtigt wird erstmalig, dass sowohl repräsentativ-demokratische als auch direkt-demokratische Entscheidungsmodi durch deliberative bzw. dialogische Beteiligungsformate ergänzt werden können. Dabei zeigt sich, dass repräsentativ-demokratische Entscheidungen weiterhin eine starke Unterstützung in der Bevölkerung erfahren, besonders auf der Bundesebene. Allerdings ist der Wunsch nach mehr Dialog und Kommunikation im Vorfeld der Entscheidungen – egal ob repräsentativ- oder direkt-demokratisch – stark und sollte bei Überlegungen zu zukünftigen Reformen demokratischen Entscheidens in der Bundesrepublik Deutschland mehr Aufmerksamkeit finden.

Background:

Coronary atherosclerosis assessed in vivo was associated with cognitive impairment; however, conflicting findings have been reported in autopsy samples.

Objective:

Our aims were to assess the association between atherosclerotic stenosis in the coronary arteries and cognitive impairment and to investigate the possibility of selection bias in an autopsy study.

Methods:

Coronary arteries were collected, and the largest luminal stenosis was measured. Sociodemographic, clinical, and cognitive information were reported by a reliable next-of-kin. The association was tested using logistic and linear regressions adjusted for sociodemographic and clinical variables. We restricted the sample to individuals that were born in 1935 or earlier and stratified the analysis by cause of death to investigate the role of selection bias.

Results:

In 253 participants (mean age = 78.0±8.5 years old, 48% male), stenosis was not associated with cognitive impairment (OR = 0.85, 95% CI = 0.69; 1.06, p = 0.15). In individuals who were born before 1936 in the absence of cardiovascular disease as the cause of death, greater stenosis was associated with cognitive impairment (OR = 4.02, 95% CI = 1.39; 11.6, p = 0.01). On the other hand, this association was not present among those born in 1935 or earlier who died of cardiovascular diseases (OR = 0.83, 95% CI = 0.60; 1.16, p = 0.28).

Conclusion:

We found that higher coronary stenosis was associated with cognitive impairment only in individuals born in 1935 or earlier and who had not died from cardiovascular diseases. Selection bias may be an important issue when investigating risk factors for chronic degenerative diseases in older individuals using autopsy samples.

Background:

Both late-life depression (LLD) and short sleep duration increase the risk of cognitive impairment. Increased insular resting-state functional connectivity (FC) has been reported in individuals with short sleep duration and dementia.

Objective:

This study aimed to investigate whether short sleep duration is associated with impaired cognition and higher insular FC in patients with LLD.

Methods:

This case– control study recruited 186 patients with LLD and 83 normal controls (NC), and comprehensive psychometric assessments, sleep duration reports and resting-state functional MRI scans (81 LLD patients and 54 NC) were conducted.

Results:

Patients with LLD and short sleep duration (LLD-SS patients) exhibited more severe depressive symptoms and worse cognitive function than those with normal sleep duration (LLD-NS patients) and NC. LLD-SS patients exhibited higher FC between the bilateral insula and inferior frontal gyrus (IFG) pars triangularis than LLD-NS patients and NC, while LLD-NS patients exhibited lower FC than NC. Increased insular FC was correlated with short sleep duration, severe depressive symptoms, and slower information processing speeds. Furthermore, an additive effect was found between sleep duration and LLD on global cognition and insular FC.

Conclusion:

LLD-SS patients exhibited impaired cognition and increased insular FC. Abnormal FC in LLD-SS patients may be a therapeutic target for neuromodulation to improve sleep and cognitive performance and thus decrease the risk of dementia.
