Published: July 2024

Introduction. Male infertility is a complex condition with many potential causes, including hormonal imbalances, anatomical problems, genetic factors, lifestyle factors and more. But today, there is a fairly large group of infertile men with unknown causes of the disease.

Objective. To analyze the taxonomic microbial diversity of testicular tissue and the urogenital tract of infertile men and to identify correlations between the microbiome and mastocytes in the testicular parenchyma.

Materials & methods. The study was performed on testicular tissue samples from infertile patients with azoospermia (n = 33). All patients were divided into two groups based on the form of azoospermia: group 1 — infertile patients with non-obstructive azoospermia (NOA) (n=21); and group 2 — infertile with obstructive azoospermia (OA) patients (n=12). The bacterial diversity of testicular tissue was studied by the method of high-performance new generation sequencing (NGS). Immunohistochemical staining with anti-MCT (Anti-Mast Cell Tryptase) was used to determine the IHC expression of mastocyte markers.

Results. The microbiome of patients with NOA differs markedly from the microbiome of patients with OA (p < 0.05). In group 1, representatives of the Enterobacteriaceae and Xanthomonadaceae families, the genera Finegoldia, Bifidobacterium, Porphiromonas, Prevotella, Peptoniphilus and Pseudomonas are significantly more often found. A distinctive feature of group 2 is the rare occurrence of the genus Prevotella. Histochemical analysis revealed mastocytosis in the in-between-canalicular stroma approximately in 83% of azoospermia cases. Mastocytes are found in tubule structures in 68% of cases and correlate with the microbiome of testicular tissue.

Conclusions. Injuries caused by mastocytes in the stroma and tubular structures are interrelated with the taxonomic diversity of testicular tissue. Moreover, the testicles of NOA-patients have a qualitatively and quantitatively more diverse spectrum both at the level of families and genera, unlike OA-patients.

Published: July 2024

Background

Limited information exists on the impact of mobile health (mHealth) use by community health workers (CHWs) on improving the use of maternal health services in sub-Saharan Africa (SSA).

Objective

This systematic review addresses 2 objectives: evaluating the impact of mHealth use by CHWs on antenatal care (ANC) use, facility-based births, and postnatal care (PNC) use in SSA; and identifying facilitators and barriers to mHealth use by CHWs in programs designed to increase ANC use, facility-based births, and PNC use in SSA using a sociotechnical system approach.

Methods

We searched for articles in 6 databases (MEDLINE, CINAHL, Web of Science, Embase, Scopus, and Africa Index Medicus) from inception up to September 2022, with additional articles identified from Google Scholar. After article selection, 2 independent reviewers performed title and abstract screening, full-text screening, and data extraction using Covidence software (Veritas Health Innovation Ltd). In addition, we manually screened the references lists of the included articles. Finally, we performed a narrative synthesis of the outcomes.

Results

Among the 2594 records retrieved, 10 (0.39%) studies (n=22, 0.85% articles) met the inclusion criteria and underwent data extraction. The studies were published between 2012 and 2022 in 6 countries. Of the studies reporting on ANC outcomes, 43% (3/7) reported that mHealth use by CHWs increased ANC use. Similarly, of the studies reporting on facility-based births, 89% (8/9) demonstrated an increase due to mHealth use by CHWs. In addition, in the PNC studies, 75% (3/4) showed increased PNC use associated with mHealth use by CHWs. Many of the studies reported on the importance of addressing factors related to the social environment of mHealth-enabled CHWs, including the perception of CHWs by the community, trust, relationships, digital literacy, training, mentorship and supervision, skills, CHW program ownership, and the provision of incentives. Very few studies reported on how program goals and culture influenced mHealth use by CHWs. Providing free equipment, accessories, and internet connectivity while addressing ongoing challenges with connectivity, power, the ease of using mHealth software, and equipment maintenance support allowed mHealth-enabled CHW programs to thrive.

Conclusions

mHealth use by CHWs was associated with an increase in ANC use, facility-based births, and PNC use in SSA. Identifying and addressing social and technical barriers to the use of mHealth is essential to ensure the success of mHealth programs.

Patient and Provider Satisfaction With a Geomapping Tool for Finding Community Family Physicians in Ontario, Canada: Cross-Sectional Online Survey Study (Preprint)
Authors: Belanger Christopher , Peixoto Cayden , Francoeur Sara , Bjerre Lise M
Published: July 2024

BACKGROUND

Language-concordant health care, or health care in a patient’s language of choice, is an important element of health accessibility that improves patient safety and comfort and facilitates an increased quality of care. However, prior research has found that linguistic minorities often face higher travel burdens to access language-concordant care compared to the general population.

OBJECTIVE

This study intended to assess patient experiences and satisfaction with an online interactive physician map that allows patients to find family physicians who speak their preferred language in and around Ottawa, Ontario, Canada, as a means of identifying areas of improvement.

METHODS

This study used an online survey with questions related to user satisfaction. Responses to Likert-scale questions were compiled as summary statistics and short-answer responses underwent thematic analysis. The study setting was Ottawa and Renfrew County, Ontario, and the surrounding region, including the province of Quebec.

RESULTS

A total of 93 respondents completed the survey and self-identified as living in Ontario or Quebec. Overall, 57 (61%) respondents were “very satisfied” or “somewhat satisfied” with the map, 16 (17%) were “neither satisfied nor dissatisfied,” and 20 (22%) were “very dissatisfied” or “somewhat dissatisfied.” We found no significant differences in satisfaction by preferred language, age group, physician attachment, or intended beneficiary. A total of 56 respondents provided short-answer responses to an open-ended question about map improvements. The most common specific suggestion was to show which physicians are accepting new patients (n=20). Other suggestions included data refreshes (n=6), user interface adjustments (n=23), and additional languages (n=2). Some participants also provided positive feedback (n=5) or expressed concern with their inability to find a family physician (n=5). Several comments included multiple suggestions.

CONCLUSIONS

While most patients were satisfied with the online map, a significant minority expressed dissatisfaction that the map did not show which family physicians were accepting new patients. This suggests that there may be public interest in an accessible database of which family physicians in Ontario are currently accepting new patients.
Advancing Brainwave Therapy: Precision Stimulation with Deep Brain Sound Technology (Preprint)
Authors: Dogan Ugur
Published: July 2024

BACKGROUND

The Deep Brain Sound Stimulation (DBSS) Brainwave Protocol offers an innovative approach to brainwave therapy, aiming to treat neurological and psychological disorders by targeting specific brain regions with sound frequencies. Traditional brainwave therapies broadly target brainwave states, while DBSS enables precise stimulation of brain locations.

OBJECTIVE

This paper aims to evaluate the efficacy and safety of the DBSS Brainwave Protocol in promoting synaptic reconnections, enhancing neural plasticity, and treating various neurological and psychological conditions.

METHODS

The study utilizes user feedback and survey data from over 350 users of the Vital Tones therapeutic apps, which apply non-invasive sound stimulation. The sessions are tailored to individual needs based on the specific disordered brain locations. User satisfaction and effectiveness were measured using structured survey responses, focusing on reported improvements and satisfaction levels.

RESULTS

The DBSS technology has shown a significant positive impact on user-reported outcomes, with satisfaction levels ranging from 30% to 95%. The extensive user base and safety record indicate a high level of reliability, with a 99.5% satisfaction rate and a refund rate of only 0.5%. User feedback underscores the protocol's efficacy in treating conditions such as anxiety, depression, and cognitive impairments.

CONCLUSIONS

DBSS represents a promising advancement in brainwave therapy, offering targeted treatment options for various neurological and psychological disorders. The protocol's precision in stimulating specific brain regions aligns with principles of neuroplasticity, promoting synaptic growth and enhancing neural connectivity. Despite its potential, further empirical validation and clinical trials are necessary to substantiate its therapeutic efficacy and long-term implications.

Authors: Chen Chen-Jung , Chen Yi-Chang
Published: July 2024

BACKGROUND

Contextual simulation-based teaching is considered an important part of the learning process for nursing students. Although the application of mirroring theory has demonstrated intervention effects on various health issues, the combination of mirroring theory with VR simulation has not yet been applied in nursing education.

OBJECTIVE

The purpose of this study was to evaluate the effect (including brain wave changes) of the integration of 360° simulation video and classroom lectures into a paediatric nursing curriculum on the technical performance of nursing students.

METHODS

Quasiexperimental research design with random assignment. Two nursing colleges in Taiwan. A total of 40 third-year nursing students were recruited and randomly assigned to the experimental group or the control group.
Methods: After class, students in the experimental group agreed to participate in a 360° simulation course during independent practice, while in the control group, traditional practice methods were used during independent study. The data included the scores of the Simulation Design Scale (SDS), the Educational Practices Questionnaire (EPQ), the Student Satisfaction and Self-Confidence in Learning Scale (SCLS) and electroencephalography recordings. The data were analysed using t tests and analysis of covariance (ANCOVA).

RESULTS

Out of 58 initial participants, 40 completed the study (experimental group: n = 13, control group: n = 27) with a 69% response rate. Significant improvements were observed in SDS and EPQ scores in the experimental group (SDS: p < .001, EPQ: p = .005). ANCOVA revealed significant between-group differences in SDS (p = .008), EPQ (p = .019), and SCLS (p = .012) scores. EEG analysis showed significant reductions in power frequencies at C3, CZ, and C4 electrodes in the experimental group (p < .001). Significant μSC differences were found at CZ (p = .028) and C4 (p = .033) electrodes between groups.

CONCLUSIONS

360° simulation video learning stimulates mirror neuron activity, fostering positive attitudes towards participation and significantly increasing postlesson confidence and satisfaction. Future research should further the in-depth understanding of the brain wave changes underlying how and under what conditions 360° contextual simulation videos support learning.

Authors: Stringer Eleah J , Rio Lily Hallett , Leitz Lorraine , Prisman Eitan , Borycki Elizabeth , Kushniruk Andre , Livergant Jonathan , Smith Sally
Published: July 2024

BACKGROUND

Advances in research and modes of information delivery provide new opportunities to access medical information. Despite this, patient information needs on head and neck cancer (HNC) treatment are not sufficiently met.

OBJECTIVE

The aim is to investigate: (1) information content required for patients with HNC and their caregivers to support confident decisions about their treatment; (2) information needs by role (e.g., patient, caregiver) and (3) the preferred format or mode of information delivery. Results will be used to inform the development and testing of a decision aid for this patient population.

METHODS

A scoping review was conducted using the Arksey and O’Malley, and Levac, Colquhoun, and O’Brien framework. The search was carried out in four databases and limited to the English language between 2012 and the search date of September 20, 2022.

RESULTS

10,495 publications were identified with 30 articles suitable for data extraction. High information needs included: details of the diagnosis, purpose and risks of medical procedures, treatment options, strategies for eating and speaking during and after treatment, lifestyle guidelines for survivorship, and facts about the human papilloma virus. Moderate information needs included: the physical and psychological domains of post-treatment, strategies to improve communication with healthcare providers, and nutrition. Information needs of HNC patients and caregivers evolved through the phases of treatment, highlighting the needs for relevant information to support collaborative decision making with their healthcare providers. Caregiver needs were underrepresented but more information on stress reduction strategies for the patient, how to play a role in treatment decisions, and where to obtain the best medical care for the patient was identified. The preferred mode of delivery for information varied and reflected the age, gender, and country of the sample populations.

CONCLUSIONS

Information needs of HNC patients, and their caregivers are not being met to a satisfactory level evidenced by the breadth of outstanding needs. Healthcare providers must consider evolving patient and caregiver information needs, addressing concerns on an individual basis to support shared decision-making. Tools are needed to support information delivery that is acceptable to patients and caregivers.

This article aimed to analyze the strength of Muhammadiyah's existence which focuses on the pillars of empowerment and strengthening of society. This paper was prepared using library research methods. Data were analyzed using qualitative descriptive analysis. Data visualization, especially regarding references and keywords that frequently appear, is assisted with VOSviewer. The results show that Muhammadiyah is an Islamic organization that has a clear and real role in empowering and strengthening of society. Muhammadiyah has a central role in the field of philanthropy, in fact this has become Muhammadiyah's identity. Al-Ma'un became the ideological-theological foundation of Muhammadiyah's struggle. The advocacy movement through community empowerment has changed the face of Muhammadiyah to become more populist. Community empowerment is carried out through action programs that directly touch on the real problems of poor and marginalized communities represented by farmers, fishermen, livestock breeders, workers, urban poor communities and people with disabilities. Women's groups who have been marginalized and tend to be subordinated have also become targets of empowerment work carried out by Muhammadiyah, especially through its wing organization, namely Aisyiyah.

Published: July 2024

The development of the economic system can be seen from the movement of the financial system which has a global impact. Therefore, the role of banking is very important for economies around the world. The aim of this research is to assess the financial performance of Islamic banks in OIC member countries (Indonesia, Malaysia, Pakistan, United Arab Emirates and Saudi Arabia) through profitability. The measure of profitability is to use the ROA ratio. The data was processed using panel data regression testing. The results of data analysis show that CAR and sukuk have a significant positive effect on profitability, while BOPO has a significant negative effect on the profitability of sharia banks in OIC member countries during the 2018 - 2022 period. Only the inflation variable has not significantly influenced the profitability of sharia banks in OIC member countries during the period. 2018 – 2022. The implication of this research is that Islamic banks must strive to increase the CAR ratio and reduce the BOPO ratio because it can significantly affect the level of bank profitability. Apart from that, Islamic banks also continue to increase sukuk issuance because it can encourage increased profits.

Authors: Maskan Mohammad , Maskur  , Fauzi Achmad
Published: July 2024

The current lecture approach demands student activity, so that students can build their own knowledge in the learning process. The student center learning (SCL) approach would be more appropriate to the current situation and conditions, where the lecturer acts as a facilitator, mediator and motivator for students in learning because students can learn from various learning sources, such as: textbooks, business experts, the internet, mass media, electronic media  or the business environment that surrounds the student's residence.

Implora is a local product brand which in 2021 launched their first skincare product, serum. In March 2022, Implora was named the best-selling serum product in e-commerce, but a few months later the product sales volume decreased due to negative reviews regarding the Implora serum. This study aims to determine how the influence of perceived quality on purchasing decisions. This research uses a quantitative approach, with an explanatory survey method. The sample was determined using the non-probability sampling method, with the acquisition cost using purposive sampling, namely respondents who know and have used Implora serum with a total sample of 155 respondents. This research uses a simple linear regression method. The results of this study indicate that there is a positive and significant influence of the perceived quality variable on the purchasing decision variable. It was also found that the effect of the quality perception variable was 36% on purchasing decisions. The results of this study can be used by industry players to increase sales volume again. For further research, other independent variables can be added because there are other factors that influence purchasing decisions besides perceived quality.

Dalam berinvestasi, tak lepas dengan menebak naik turunya harga agar tidak rugi dalam berinvestasi. Hal ini diperlukan dukungan teknologi untuk dapat mengetahui informasi dalam menghadapi harga yang selalu berubah-ubah setiap hari dan bahkan setiap jamnya. Investor dalam hal ini untuk komoditi emas harus dapat memprediksi harga yang selalu serubah-ubah tersebut sebelum melakukan trasnsaksi jual maupun beli, agar investor tepat dalam melakukan aktivitas jual maupun beli saham. Dengan demikian, penulis akan membuat penelitian mengenai prediksi harga emas dunia, yang bermanfaat bagi investor maupun masyarakat yang akan melakukan jual beli emas dalam bentuk saham ataupun barang agar tepat dalam mengambil keputusan. Tujuan dari prediksi adalah memperkecil kesalahan, sehingga selisih antara perkiraan dengan kejadian yang sebenarnya diminimalkan. Suatu prediksi tidak dapat dipastikan tepat sepenuhnya, tetapi memungkinkan untuk memberikan hasil yang mendekati dengan kejadian sebenarnya. Algoritma yang digunakan dalam penelitian ini adalah Convolutional Neural Network (CNN). CNN termasuk dalam bidang Deep Learning (DL), yang termasuk dalam sub bidang dari Machine Learning (ML), yang mana menerapkan konsep dasar algoritma ANN dengan lapisan yang lebih banyak. Dalam penelitian ini, penulis menggunakan pendekatan univariate CNN. Dilakukan beberapa pengujian pada parameter model CNN. Hasil terbaik ditunjukan pada model 1 yaitu pengujian dense kondisi 5, yaitu dengan parameter model filters = 64, kernel = 2, pooling = 2, epochs = 2.000, dan dense = 50 dengan hasil RMSE yaitu 690,40.

Data merupakan file yang dapat bersifat rahasia sehingga membutuhkan sebuah proses pengamanan data untuk menjaga kerahasiaannya. Kripotgrafi yaitu proses pengamanan data yang dapat digunakan berdasarkan penggunaan algoritma salah satunya AES. AES adalah algoritma modern yang dapat dimodifikasi untuk meningkatkan konfusi dan difusi dalam kriptografi. Kombinasi AES dapat dilakukan menggunakan Polybius yang memiliki sifat difusi kriptografi. Penelitian ini melakukan modifikasi AES menggunakan matriks Polybius berukuran 6x6 dan 10x10 yang dilakukan pada plainteks maupun plainteks dan kunci. Analisa dilakukan berdasarkan tingkat perubahan bit tertinggi yang terdapat pada modifikasi II pada plainteks dan kunci matriks 6x6 yaitu sebesar 51,8% menggunakan uji avalanche effect. Hasil dari AE dibandingkan dengan hasil yang diharapkan menggunakan chi square dengan hasil AES modifikasi dapat meningkatkan AE sebesar 5% dengan taraf nyata 0,05 dan derajat kebebasan 4. Waktu eksekusi diuji pada penelitian dengan hasil AES modifikasi lebih tinggi dibandingkan AES standar dikarenakan kompleksitas dari setiap algoritma berbanding lurus dengan proses waktu enkripsi maupun dekripsi.

Published: July 2024

Socket TCP adalah abstraksi yang digunakan aplikasi untuk mengirim dan menerima data melalui koneksi antar dua host dalam jaringan komputer. Jaringan yang biasa kita gunakan bersifat publik yang sangat rentan akan penyadapan data. Masalah ini dapat teratasi dengan menggunakan algoritma kriptografi pada socket TCP, salah satunya menggunakan algoritma RSA. Tingkat keamanan algoritma RSA standar memiliki celah keamanan pada kunci publik ataupun privat yang berasal dari inputan 2 bilangan prima saat pembangkitan kunci, begitupun dengan algoritma improvisasi RSA meskipun menggunakan 4 bilangan prima akan tetapi mulai dari pembangkitan kunci hingga dekripsi memiliki proses yang sama persis dengan RSA standar sehingga tingkat keamanan dari kedua algoritma tersebut sama – sama kurang aman meskipun jumlah bilangan prima dari algoritma improvisasi RSA lebih banyak dari RSA standar. Peningkatan keamanan dapat dilakukan dengan memodifikasi algoritma RSA dengan menggunakan ESRKGS (Enhanced and Secured RSA Key Generation Scheme). ESRKGS RSA memiliki kelebihan yang utama pada segi keamanannya. ESRKGS RSA secara total memodifikasi algoritma RSA terutama pada bagian pembangkitan kunci dan diklaim mempunyai performa lebih cepat dari algoritma improvisasi RSA yang sama – sama menggunakan 4 bilangan prima dan tentunya lebih aman dari serangan known plaintext attack dan fermat factorization attack yang akan penulis gunakan untuk pengujian keamanan pada penelitian ini. Hasil pengujian performa waktu pembangkitan kunci dengan panjang bit 256 bit, 512 bit, dan 1024 bit serta untuk proses enkripsi dan dekripsi panjang karakter yang digunakan adalah 100, 250, dan 400 menunjukkan bahwa algoritma ESRKGS RSA lebih baik dibandingkan  algoritma improvisasi RSA. Pengujian kemanan menggunakan known plaintext attack dan fermat factorization attack menunjukkan bahwa algoritma ESRKGS RSA lebih baik dibandingkan  algoritma RSA standar dan improvisasi RSA.
