Authors: Liu Kien Ting , Wan Rosli Wan Rosilawati , Yusuf Azlina , Lean Keng Soon 
Published: October 2021

Background: Breast cancer genetic (BRCA) testing for cancer susceptibility is an emerging technology in medicine.
Objective: This study assessed the knowledge and attitude of nurses regarding BRCA genetic testing in a tertiary teaching hospital in Malaysia.
Methods: A descriptive cross-sectional study was conducted among 150 nurses using a simple random sampling technique in a tertiary teaching hospital in northeast peninsular Malaysia. Data were collected using a self-administered questionnaire consisting of socio-demographic data, assessing nurses’ knowledge and attitude regarding BRCA genetic testing. Fisher exact test analysis was used to determine the association between socio-demographic characteristics with knowledge and attitude level. In addition, the overall knowledge and attitude were analysed using the sum score of each outcome based on Bloom’s cut-off point.
Results: Of the 150 nurses, 66.7% had high knowledge level about BRCA genetic testing, and 58% were positive towards genetic testing. The participants’ mean age was 28.9 years (SD = 6.70). Years of working experience (p = 0.014) significantly influenced knowledge level on BRCA genetic testing, whereas speciality working experience (p <0.001) significantly influenced BRCA genetic testing attitudes.
Conclusions: The results show that most nurses have adequate knowledge of BRCA genetic testing. However, their attitude could be termed negative. Therefore, targeted education programs on BRCA genetic testing and risk are needed to improve the knowledge and attitude of nurses and, ultimately, can educate the women and increase health-seeking behaviour among eligible women.

Published: October 2021

Background: Older adults spend a considerable amount of time inside their residences; however, most research investigates out-of-home mobility and its health correlates. We measured indoor mobility using room-to-room transitions, tested their psychometric properties, and correlated indoor mobility with cognitive and functional status.Materials and Methods: Community-dwelling older adults living alone (n = 139; age = 78.1 ± 8.6 years) from the Oregon Center for Aging &amp; Technology (ORCATECH) and Minority Aging Research Study (MARS) were included in the study. Two indoor mobility features were developed using non-parametric parameters (frequency; stability): Indoor mobility frequency (room-to-room transitions/day) was detected using passive infrared (PIR) motion sensors fixed on the walls in four geographic locations (bathroom; bedroom; kitchen; living room) and using door contact sensors attached to the egress door in the entrance. Indoor mobility stability was estimated by variances of number of room-to-room transitions over a week. Test-retest reliability (Intra-class coefficient, ICC) and the minimal clinically important difference (MCID) defined as the standard error of measurement (SEM) were generated. Generalized estimating equations models related mobility features with mild cognitive impairment (MCI) and functional status (gait speed).Results: An average of 206 days (±127) of sensor data were analyzed per individual. Indoor mobility frequency and stability showed good to excellent test-retest reliability (ICCs = 0.91[0.88–0.94]; 0.59[0.48–0.70]). The MCIDs of mobility frequency and mobility stability were 18 and 0.09, respectively. On average, a higher indoor mobility frequency was associated with faster gait speed (β = 0.53, p = 0.04), suggesting an increase of 5.3 room-to-room transitions per day was associated with an increase of 10 cm/s gait speed. A decrease in mobility stability was associated with MCI (β = −0.04, p = 0.03).Discussion: Mobility frequency and stability in the home are clinically meaningful and reliable features. Pervasive-sensing systems deployed in homes can objectively reveal cognitive and functional status in older adults who live alone.

Published: October 2021

Background: During an epidemic of a novel infectious disease, frontline medical staff suffer from high psychological stress. Previous studies have found that traumatic childhood experiences are associated with mental and physical health in adulthood. Anxiety and depression were measured and analyzed in relation to childhood trauma and coping styles. This study aims to explore the correlational study between traumatic childhood experiences and coping styles among nurse practitioners.Method: This study sampled 278 nurse practitioners from hospitals designated for the treatment of the novel coronavirus in Sichuan Province. The study measures included the Simplified Coping Style Questionnaire and the Childhood Trauma Questionnaire-Short Form. This research intends to use correlational study methods to explore the relationship between the two factors.Results: Statistical analysis showed that there was no statistically significant difference in the general demographic data between the two groups.Conclusion: Childhood traumatic experiences have a significant impact on the active coping of nurse practitioners, and active coping may be emotionally protective for nurse practitioners.

Published: October 2021

Introduction: Persons with spinal cord injury (SCI) often report high levels of neuropathic pain (NP) and poor well-being, which may result from increased inflammation. This study examined the impact of sub-maximal aerobic exercise on NP, inflammation and psychological affect among adults with SCI.Methods: Eight active adults with tetraplegia (n-4, AIS A-C) and paraplegia (n = 4, AIS A-C) performed 30-min of arm-crank aerobic exercise and reported their ratings of perceived exertion (RPE) each minute. Measures of NP, affect, and inflammatory cytokines (IL-6, IL-10, IL-1ra, TNF-α) were taken pre-(T0), immediately post-(T1), and 90-min post-exercise (T2).Results: NP decreased between T0 and T1 for tetraplegics (−60%, d = 0.47; CI = −0.32, 2.02) and paraplegics (−16%, d = 0.15; CI = −0.30, 0.90). Correlations between change in cytokines and change in NP were medium-to large for tetraplegics (rs ranged from −0.820 to 0.965) and paraplegics (rs ranged from −0.598 to 0.833). However, the pattern of correlations between change in cytokines and affect was inconsistent between groups. Lower baseline levels of IL-1ra predicted greater decreases in NP immediately post-exercise (r = 0.83, p = 0.01).Conclusion: Sub-maximal exercise can positively impact NP for some persons with SCI. Further experimental research should identify the optimal exercise intensity to reduce NP for persons with SCI, in addition to understanding biomarkers which may predict changes in NP.Clinical Trial Registration:www.ClinicalTrials.gov, identifier NCT03955523.

Objectives: DNA methyltransferases (DNMTs) and the histone modification H3K9ac are epigenetic markers. This study aimed to describe the immunohistochemical expression of DNMT1, DNMT3A, DNMT3B, and H3K9ac in the dental follicle (DF), ameloblastoma (AME), and ameloblastic carcinoma (AC), correlating these expressions with the recurrence and aggressive behavior in ameloblastoma.Study Design: Immunohistochemical reactions were performed in 10 human DFs, 38 ameloblastomas, and 6 AC samples. Another 59 ameloblastomas assembled in a tissue microarray were used to compare the immunoexpression with the clinical, radiographic, and histopathological characteristics and the presence of BRAFv600e mutation. Each slide was digitized as a high-resolution image and quantified by Aperio ScanScope Nuclear V9 software. All statistical analyzes were performed using GraphPad Prism statistical software.Results: DNMT3B expression was higher in ameloblastomas than in the DFs, while the AC overexpressed all proteins. The ameloblastomas with BRAFv600e mutation, vestibular/lingual, or vestibular/palatine bone cortical disruption and maxilla involvement showed DNMT1 overexpression, while recurrent cases had high DNMT3B levels.Conclusions: DNA methylation and histone modification might play a role in the development, clinical aggressiveness, and recurrence rates of ameloblastoma, such as the progression to AC. Further investigation about gene methylations in ameloblastomas is needed to better understand its relationship with aggressiveness and recurrence.

Published: October 2021

INTISARIBanjir adalah bencana alam yang sulit di deteksi kapan akan datang terutama di musim hujan. Meskipun sudah dilakukan upaya dengan melakukan analisis terhadap data curah hujan serta tinggi permukaan air setiap periodenya, namun upaya tersebut dirasa masih belum dapat menyelesaikan permasalahan yang ada. Selain dari sisi manusia nya sendiri, solusi dari sisi teknologi juga diharapkan dapat penyelesaian permasalahan ini. Teknologi untuk deteksi dini bencana banjir akan dibutuhkan sebagai alternatif untuk membantu menyelesaikan permasalahan serta membantu dalam proses pengambilan keputusan guna meningkatkan kinerja instansi yang bekerja untuk memantau volume air sungai sehingga memperoleh kondisi air yang lebih cepat dan akurat. Tinggi permukaan air tentu menjadi salah satu faktor yang menyebabkan potensi banjir dimana permukaan air dapat diukur. DTMF merupakan metode pensinyalan yang nantinya akan dipadukan dengan sensor yang dapat digunakan untuk mengukur ketinggian permukaan air yang hasilnya nanti akan dikirim melalui gelombang radio. Dengan pengiriman sinyal melalui gelombang radio ini maka akan lebih efektif karena tidak memerlukan biaya seperti halnya melalui sms dan IoT.Kata kunci— DTMF, Arduino, Pendeteksi Banjir, SWOT, Gelombang Radio ABSTRACTFloods are natural disasters that are difficult in the detection of when it will come mainly in the rainy season. Despite efforts by conducting an analysis of the data of rainfall and high water levels at each, but those efforts proved still unable to resolve the existing problems. Aside from the human side of his own, the solution from the tech side is also expected to be the resolution of this issue. Technology for early detection of catastrophic flooding will be required as an alternative to help solve problems as well as help in the decision-making process in order to improve the performance of agencies who work to monitor the volume of river water so obtain water conditions more quickly and accurately. High water levels would certainly be one of the factors that lead to potential flooding where water levels can be measured. DTMF signalling is a method which will be combined with sensors that can be used to measure the height of the surface of the water which results will be sent via radio waves. With the delivery of the signal via radio waves it then it will be more effective because it doesn't cost as much as through sms and IoT.Keyword — DTMF, Arduino, Flood Detection, SWOT, Radio Wave

Published: October 2021

Fault Seal Analysis (FSA) adalah analisis untuk menentukan patahan/sesar bersifat sealing (tersekat) atau leaking (bocor). Salah satu metode untuk menentukan FSA adalah Shale Gouge Ratio (SGR) yang pertama kali dikemukaan oleh Yielding (1997). Tujuan penelitian ini menentukan sealing atau leaking patahan pada batugamping Formasi Kais lapangan “AR” Cekungan Bintuni, Papua Barat, dan analisis pengaruh ketebalan lapisan (∆z) dan volume shale (Vsh) dalam rumus SGR. Data penelitian yang digunakan yaitu satu sumur minyak (sumur AR-3), penampang lapisan formasi, dan throw dari 3 (tiga) patahan (F1, F2, F3) di sekitar sumur tersebut. Metode penelitian adalah SGR untuk menentukan sealing atau leaking, sedangkan analisis pengaruh ketebalan lapisan (∆z) dan volume shale (Vsh) dalam rumus SGR dilihat berdasarkan R square dari grafik antara ∆z dengan SGR, dan grafik antara Vsh dengan SGR, untuk tiga patahan tersebut. Hasil penelitiannya yaitu; dari tujuh lapisan di dalam satu tubuh formasi Kais, didapatkan berbagai macam sifat leaking, sealing / leaking, dan sealing, di tiga patahan (F1, F2, F3). Namun, SGR Formasi Kais dengan tebal 270 ft dan Vsh 21%, maka nilai SGR selalu lebih dari 100% yang berarti sealing. Hasil nilai R square grafik Δz terhadap SGR = 0,743 jauh lebih tinggi dibanding Vsh terhadap SGR = 0,036. Kesimpulannya; nilai total ketebalan shale (Δz*Vsh) harus lebih kecil sama dengan dengan nilai throw fault-nya, atau dapat ditulis Δz*Vsh ≤ Throw Fault, jika tidak, maka nilai SGR akan selalu melebihi 100%. Rumus SGR jauh lebih dipengaruhi oleh ketebalan lapisan (Δz), dibanding dengan Volume Shale (Vsh).
