Mixed Feelings about the Diagnosis of Type 2 Diabetes Mellitus: A Consequence of Adjusting To Health Related Quality Of Life
This study aims to explore patients’ reactions to the diagnosis of type 2 diabetes mellitus (T2DM) and their health related quality of life. We adopted a qualitative exploratory study design using a thematic analysis. Twelve patients with T2DM for more than a 2-year duration were interviewed using a semi-structured interview guide. Both purposive and theoretical samplings were used for data collection. The in-depth interviews were audio-taped and transcribed verbatim, followed by line-by-line coding and constant comparison to identify the themes. Data management was facilitated using Nvivo 10. Patients shared their mixed feelings about the diagnosis of T2DM. Six domains of quality of life emerged from these interviews, namely physical and social functioning, work function and social obligations, dietary freedom and conforming to treatment standard. Diabetes management needs to take these themes and patients’ feelings associated with their quality of life into consideration
Indicators of the molecular pathogenesis of virulent Newcastle disease virus in chickens revealed by transcriptomic profiling of spleen
Newcastle disease virus (NDV) has caused significant outbreaks in South-East Asia, particularly in Indonesia in recent years. Recently emerged genotype VII NDVs (NDV-GVII) have shifted their tropism from gastrointestinal/respiratory tropism to a lymphotropic virus, invading lymphoid organs including spleen and bursa of Fabricius to cause profound lymphoid depletion. In this study, we aimed to identify candidate genes and biological pathways that contribute to the disease caused by this velogenic NDV-GVII. A transcriptomic analysis based on RNA-Seq of spleen was performed in chickens challenged with NDV-GVII and a control group. In total, 6361 genes were differentially expressed that included 3506 up-regulated genes and 2855 down-regulated genes. Real-Time PCR of ten selected genes validated the RNA-Seq results as the correlation between them is 0.98. Functional and network analysis of Differentially Expressed Genes (DEGs) showed altered regulation of ElF2 signalling, mTOR signalling, proliferation of cells of the lymphoid system, signalling by Rho family GTPases and synaptogenesis signalling in spleen. We have also identified modified expression of IFIT5, PI3K, AGT and PLP1 genes in NDV-GVII infected chickens. Our findings in activation of autophagy-mediated cell death, lymphotropic and synaptogenesis signalling pathways provide new insights into the molecular pathogenesis of this newly emerged NDV-GVII

Development of a three-dimensional printed heart from computed tomography images of a plastinated specimen for learning anatomy
Copyright © 2020 The Author(s) and Korean Association of ANATOMISTS. Learning anatomy is commonly facilitated by use of cadavers, plastic models and more recently three-dimensional printed (3DP) anatomical models as they allow students to physically touch and hold the body segments. However, most existing models are limited to surface features of the specimen, with little opportunity to manipulate the structures. There is much interest in developing better 3DP models suitable for anatomy education. This study aims to determine the feasibility of developing a multi-material 3DP heart model, and to evaluate students' perceptions of the model. Semi-automated segmentation was performed on computed tomgoraphy plastinated heart images to develop its 3D digital heart model. Material jetting was used as part of the 3D printing process so that various colors and textures could be assigned to the individual segments of the model. Morphometric analysis was conducted to quantify the differences between the printed model and the plastinated heart. Medical students' opinions were sought using a 5-point Likert scale. The 3DP full heart was anatomically accurate, pliable and compressible to touch. The major vessels of the heart were color-coded for easy recognition. Morphometric analysis of the printed model was comparable with the plastinated heart. Students were positive about the quality of the model and the majority of them reported that the model was useful for their learning and that they would recommend their use for anatomical education. The successful feasibility study and students' positive views suggest that the development of multi-material 3DP models is promising for medical education
Prevalence and factors associated with anxiety during the COVID-19 pandemic among Malaysians: a cross-sectional study
The COVID-19 pandemic is a significant public health threat with wide-reaching psychological implications. The drastic changes in lifestyle due to the implementation of the movement control order (MCO) were associated with adverse effects on mental health. This study aimed to examine the prevalence of anxiety among Malaysians during the COVID-19 pandemic and its associated factors. The following questionnaires were self-administered online through google form which included: (i) Generalised Anxiety Disorder-7; (ii) Short Boredom Proneness Scale; (iii) Short Scale for Measuring Loneliness in Large Surveys; and (iv) The World Health Organisation (WHO) well-being index. Higher scores denoted higher levels of anxiety, boredom, loneliness, and well-being. Out of the 543 participants, more than half (55.2%) reported mild (25.6%), moderate (13.8%) to severe (19.8%) anxiety. Multiple logistic regression showed higher odds of moderate to severe anxiety were reported among those divorced/separated/widowed (aOR 6.778, 95% CI [1.200, 38.296]), adults aged 25 to 34 years (aOR 2.038, 95% CI [1.049, 3.958]), 35 to 44 years (aOR 2.279, 95% CI [1.064, 4.882]), and with higher boredom levels (aOR 1.063, 95% CI [1.035, 1.092]). One in five Malaysians surveyed experienced severe anxiety. Adults within the working age range (between 25 and 44 years old) were at higher odds of having anxiety. Boredom increased the odds of anxiety compared to loneliness, well-being and coping. Thus, addressing the risk factors through public health messages is deemed important
Malaysian primary care doctors' views on men's health: an unresolved jigsaw puzzle
<p>Abstract</p> <p>Background</p> <p>Men have been noted to utilise health care services less readily then women. Primary care settings provide an opportunity to engage men in health care activities because of close proximity to the target group (men in the community). Understanding attitudes towards men's health among Malaysian primary care doctors is important for the effective delivery of health services to men. We aimed to explore the opinions and attitudes of primary care doctors (PCDs) relating to men's health and help-seeking behaviour.</p> <p>Methods</p> <p>A qualitative approach to explore the opinions of 52 PCDs was employed, using fourteen in-depth interviews and eight focus group discussions in public and private settings. Purposive sampling of PCDs was done to ensure maximum variation in the PCD sample. Interviews were recorded and transcribed verbatim for analysis. Open coding with thematic analysis was used to identify key issues raised in the interview.</p> <p>Results</p> <p>The understanding of the concept of men's health among PCDs was fragmented. Although many PCDs were already managing health conditions relevant and common to men, they were not viewed by PCDs as "men's health". Less attention was paid to men's help-seeking behaviour and their gender roles as a potential determinant of the poor health status of men. There were opposing views about whether men's health should focus on men's <it>overall </it>health or a more focused approach to sexual health. There was also disagreement about whether special attention was warranted for men's health services. Some doctors would prioritise more common conditions such as hypertension, diabetes and hypercholesterolaemia.</p> <p>Conclusions</p> <p>The concept of men's health was new to PCDs in Malaysia. There was wide variation in understanding and opposing attitudes towards men's health among primary care doctors. Creating awareness and having a systematic approach would facilitate PCDs in delivering health service to men.</p

Comparative Genomics of the Anopheline Glutathione S-Transferase Epsilon Cluster
Enzymes of the glutathione S-transferase (GST) family play critical roles in detoxification of xenobiotics across many taxa. While GSTs are ubiquitous both in animals and plants, the GST epsilon class (GSTE) is insect-specific and has been associated with resistance to chemical insecticides. While both Aedes aegypti and Anopheles gambiae GSTE clusters consist of eight members, only four putative orthologs are identifiable between the species, suggesting independent expansions of the class in each lineage. We used a primer walking approach, sequencing almost the entire cluster from three Anopheles species (An. stephensi, An. funestus (both Cellia subgenus) and An. plumbeus (Anopheles subgenus)) and compared the sequences to putative orthologs in An. gambiae (Cellia) in an attempt to trace the evolution of the cluster within the subfamily Anophelinae. Furthermore, we measured transcript levels from the identified GSTE loci by real time reverse transcription PCR to determine if all genes were similarly transcribed at different life stages. Among the species investigated, gene order and orientation were similar with three exceptions: (i) GSTE1 was absent in An. plumbeus; (ii) GSTE2 is duplicated in An. plumbeus and (iii) an additional transcriptionally active pseudogene (ψAsGSTE2) was found in An. stephensi. Further statistical analysis and protein modelling gave evidence for positive selection on codons of the catalytic site in GSTE5 albeit its origin seems to predate the introduction of chemical insecticides. Gene expression profiles revealed differences in expression pattern among genes at different life stages. With the exception of GSTE1, ψAsGSTE2 and GSTE2b, all Anopheles species studied share orthologs and hence we assume that GSTE expansion generally predates radiation into subgenera, though the presence of GSTE1 may also suggest a recent duplication event in the Old World Cellia subgenus, instead of a secondary loss. The modifications of the catalytic site within GSTE5 may represent adaptations to new habitats

Digital Gene Expression Analysis Based on Integrated De Novo Transcriptome Assembly of Sweet Potato [Ipomoea batatas (L.) Lam.]
Background: Sweet potato (Ipomoea batatas L. [Lam.]) ranks among the top six most important food crops in the world. It is widely grown throughout the world with high and stable yield, strong adaptability, rich nutrient content, and multiple uses. However, little is known about the molecular biology of this important non-model organism due to lack of genomic resources. Hence, studies based on high-throughput sequencing technologies are needed to get a comprehensive and integrated genomic resource and better understanding of gene expression patterns in different tissues and at various developmental stages. Methodology/Principal Findings: Illumina paired-end (PE) RNA-Sequencing was performed, and generated 48.7 million of 75 bp PE reads. These reads were de novo assembled into 128,052 transcripts ($100 bp), which correspond to 41.1 million base pairs, by using a combined assembly strategy. Transcripts were annotated by Blast2GO and 51,763 transcripts got BLASTX hits, in which 39,677 transcripts have GO terms and 14,117 have ECs that are associated with 147 KEGG pathways. Furthermore, transcriptome differences of seven tissues were analyzed by using Illumina digital gene expression (DGE) tag profiling and numerous differentially and specifically expressed transcripts were identified. Moreover, the expression characteristics of genes involved in viral genomes, starch metabolism and potential stress tolerance and insect resistance were also identified
