Prevalence of diabetic retinopathy and its associated risk factors among adults in Ethiopia: a systematic review and meta-analysis.

Diabetic retinopathy is a complication of diabetes mellitus and a leading cause of blindness and visual impairment globally. Limited information existed on the epidemiology of diabetic retinopathy at the national level in Ethiopia. Thus, the objective of this review was to determine the pooled prevalence of diabetic retinopathy and its associated risk factors in Ethiopia. A systematic review and meta-analysis was conducted using previous primary studies that were found in electronic databases such as Web of Science, Scopus, PubMed, CINHAL, Google Scholar, and online African journals. We evaluated the quality of the included studies using the Newcastle-Ottawa Assessment Scale. The random-effects model was applied because heterogeneity was expected. I-Square and the Cochrane Q statistics were used to evaluate heterogeneity. Publication bias was examined using Egger's test and a funnel plot. A random-effect meta-analysis was applied to pool the odds ratios of risk factors to determine the association between the independent and dependent variables. After 598 articles were found, 22 studies that met the eligibility requirements were included. The pooled prevalence of retinopathy among patients with diabetes in Ethiopia was 24.35% (95% CI: 18.88-29.83), with considerable heterogeneity (I2 = 98.18%, p < 0.001). Ten years and longer with diabetes (AOR = 4.36, 95% CI: 1.71-7.01), hypertension (AOR = 2.54, 95% CI: 1.45-3.63), poor glycemic control (AOR = 3.83, 95% CI: 1.62-6.04), and positive proteinuria (AHR = 1.55, 95% CI: 1.02-2.07) were risk factors for diabetic retinopathy. Retinopathy affects one in four patients with diabetes. Diabetic patients with longer duration, hypertension, poor glycemic control, and positive proteinuria should receive special care.

SUPERLOTAÇÃO DOS SERVIÇOS DE EMERGÊNCIA: IMPLICAÇÕES PARA A SEGURANÇA DO PACIENTE E PARA O TRABALHO DA EQUIPE DE SAÚDE

Introduction: Overcrowding in emergency services is a reality that is likely to worsen, making it necessary to implement measures to ensure patient safety in the care provided. Objective: To describe the implications of overcrowding for patient safety and the work/daily routine of the healthcare team. Methodology: This is a bibliographic review article in which an exploratory, qualitative approach was used. The search for articles, theses, dissertations, book chapters was conducted in databases such as Lilacs BDNF, Medline, Scielo, and university repositories containing scientific journals. Publications were sought that addressed the topic in Portuguese, within the period of 2015 to 2024. The results yielded 34 articles related to the topic, of which 12 were selected for this study, in addition to the book by the Joint Commission International (JCI), “Managing Patient Flow: Strategies and Solutions for Overcoming Overcrowding.” Results and Discussion: It is well known that patient safety is a globally discussed topic and a recurring requirement for institutions undergoing accreditation processes. In this context are healthcare professionals, who, due to the nature of their work, are subject to committing/experiencing adverse events within their professional environment. Final Considerations: The consequences of overcrowding bring numerous implications for the work of healthcare professionals and for patient safety, such as reduced quality of care, exhaustion of healthcare professionals, increased risk of infections, inequality in access to care, impact on the efficiency of the healthcare system, and increased costs, making it a critical challenge for both public and private healthcare systems.

Arthroscopic assisted versus open core decompression for osteonecrosis of the femoral head: A systematic review and meta-analysis.

Minimally invasive treatment options for osteonecrosis of the femoral head (ONFH) have been a prominent area of research in recent years. Arthroscopic-assisted treatments have been applied in the clinical management of ONFH; however, high-quality evidence verifying their effectiveness and safety is still lacking. To systematically assess the clinical efficacy and safety of arthroscopic-assisted core decompression (AACD) in treating ONFH. A comprehensive literature search was conducted in PubMed, Web of Science, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, WanFang, and the Chinese BioMedical Literature Database, from inception to June 25, 2024. We identified randomized controlled trials and non-randomized controlled studies on AACD for the treatment of ONFH based on predefined inclusion and exclusion criteria. A meta-analysis was performed using Review Manager 5.4.1 and Stata 17.0 software. The analyzed outcomes included operative time, intraoperative blood loss, length of hospital stay, postoperative femoral head collapse rate, Harris hip score, and postoperative complication rate. The Grades of Recommendations, Assessment, Development, and Evaluations (GRADE) system was used to assess the quality of evidence for the outcome indicators. A total of fourteen studies were included in this meta-analysis, comprising 1,063 patients-541 in the core decompression (CD) group and 522 in the AACD group. The meta-analysis revealed no significant differences between the two groups in terms of intraoperative blood loss, length of hospital stay, 12-month postoperative Harris hip score, or overall postoperative complication rate (P > 0.05). However, the AACD group had a longer operative time (MD = 31.19, 95% Cl: 5.32 to 57.07, P = 0.02) and a lower overall postoperative femoral head collapse rate (RR = 0.49, 95% Cl: 0.27 to 0.89, P = 0.02) compared with the CD group. Additionally, the AACD group showed significant improvements in Harris hip scores at 3 months (MD = 6.39, 95% Cl: 5.44 to 7.33, P < 0.00001), 6 months (MD = 7.56, 95% Cl: 6.63 to 8.49, P < 0.00001), ≥ 24 months (MD = 7.00, 95% Cl: 4.80 to 9.21, P < 0.00001), and at the last follow-up (MD = 6.89, 95% Cl: 5.30 to 8.48, P < 0.00001) compared to the CD group. The GRADE evidence assessment indicated that the overall postoperative complication rate was supported by moderate-quality evidence, while the evidence for operative time, intraoperative blood loss, postoperative femoral head collapse rate, and Harris hip score was of low quality. The evidence for length of hospital stay was deemed very low quality. This meta-analysis suggests that AACD is an effective and safe treatment for patients with ONFH. However, due to the limited quantity and quality of the included studies, these results should be interpreted with caution. Further high-quality studies are recommended to confirm these findings.

Instruments for Measuring the Burden of Family Caregivers of Cancer Patients: A Systematic Review of Measurement Properties.

This study identifies instruments for assessing the burden on family caregivers of cancer patients and evaluates their psychometric properties using COSMIN criteria. A systematic review based on COSMIN methodology. The review adhered to PRISMA guidelines. Relevant studies were identified through searches in PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure, Wanfang Database, and China Science and Technology Journal Database, covering literature from inception to September 2024. Included studies focused on developing or validating measurement tools and assessing psychometric properties such as reliability, internal consistency and construct validity. Two independent researchers screened the literature, extracted data and evaluated psychometric properties using COSMIN criteria while assessing evidence quality via the GRADE method. A total of 32 studies were included, encompassing 17 tools for assessing caregiver burden. None reported measurement error, cross-cultural validity or responsiveness. The Caregiver's Burden Scale in End-of-Life Care (CBS-EOLC) demonstrated strong reliability, validity and internal consistency, receiving a strong recommendation for clinical practice. In contrast, the Zarit Burden Interview (ZBI), Family Caregiver Burden Interview Scale (FBIS) and Bakas Caregiving Outcomes Scale (BCOS) are not recommended due to insufficient supporting evidence. Other tools showed weak evidence, leading to weak recommendations. The CBS-EOLC exhibits comprehensive psychometric properties suitable for clinical applications. The ZBI, FBIS and BCOS lack adequate supporting evidence and are not recommended. Future research should focus on measurement error, cross-cultural validity and responsiveness to enhance these tools' applicability and reliability. This review provides evidence for healthcare providers to select instruments for assessing caregiver burden in cancer patients. This systematic review highlights the need for comprehensive assessments of caregiver burden based on COSMIN guidelines. This study is a systematic review with no patient or public participation.

Research perspectives of supply chain knowledge management: A bibliometrics study

The purpose of this article is to present a bibliometric analysis of scientific publications on knowledge management (KM) and supply chain (SC), provide an overview of research activities in this field and recognise its most substantial and fundamental aspects. In addition, this study aims to quantitatively analyse KM in SC in other words supply chain knowledge management (SCKM) research trends, forecasts and citations from 1999 to 2021 in Web of Science (WOS). A total of 499 documents related to SCKM research were collected from the following databases: SCI-EXPAND, SSCI, AHCI and ESCI. These documents were carefully reviewed and subjected to bibliometric data analysis techniques. We map the time trend, disciplinary distribution, high-frequency keywords and topics, major authors and influential publications to show emerging topics. Based on the findings of other researchers, many implications emerged that improve one’s understanding of the identity of SCKM as a distinct multi-discipline scientific field, and its publication has grown significantly since 2018. SC papers were published in engineering and Operations Research and Management Science journals, while the coverage of research topics related to KM and SCKM is broader and more interdisciplinary than those of SC papers. High-frequency keywords associated with SCKM research are listed. From the citation of 499 papers with both KM and SC as keywords, we find the most popular one.

Effectiveness of Acupuncture for Diabetic Nephropathy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background: This systematic review and meta-analysis aimed to explore the effectiveness of acupuncture for patients with diabetic nephropathy (DN). Methods: Nine online databases were searched: China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang Data Knowledge Service Platform, Chinese BioMedical Literature Database, China Clinical Trial Centre, Embase, PubMed, the Cochrane Library, and Web of Science. The search period was from the establishment of the database to 1 September 2023. The quality of the literature was evaluated using the Cochrane Risk of Bias Assessment Tool, and the data were analyzed using STATA/MP17 and Review Manager 5.3 software. Results: A total of 221 articles were identified, and 13 studies were included. The total sample size was 899, including 452 and 447 cases in the experimental and control groups, respectively. The meta-analysis showed that acupuncture combined with modern medical treatment was effective in improving urinary albumin excretion rate, 24 h urinary microalbumin, serum creatinine, blood urea nitrogen, fasting plasma glucose, 2 h postprandial plasma glucose, total cholesterol, high-density lipoprotein cholesterol, hypersensitive C-reactive protein, and interleukin-6 in patients with DN. Adverse events were reported in only one trial; therefore, this review cannot yet conclude on the safety of acupuncture intervention in DN. Conclusion: The clinical efficacy of acupuncture combined with modern medicine in DN is superior to that of modern medicine alone. To better evaluate the efficacy and safety of acupuncture intervention for DN, more rigorously designed large-sample, multicentre, randomized controlled trials are needed to provide evidence support in the future.

Strategic policy options to improve quality and productivity of biomedical research.

Emerging societal expectations from biomedical research and intensifying international scientific competition are becoming existential matters. Based on a review of pertinent evidence, this article analyzes challenges and formulates public policy recommendations for improving productivity and impact of life sciences. Critical risks include widespread quality defects of research, particularly non-reproducible results, and narrow access to scientifically sound information giving advantage to health misinformation. In funding life sciences, the simultaneous shift to nondemocratic societies is an added challenge. Simply spending more on research will not be enough in the global competition. Considering the pacesetter role of the federal government, five national policy recommendations are put forward: (i) funding projects with comprehensive expectations of reproducibility; (ii) public-private partnerships for contemporaneous quality support in laboratories; (iii) making research institutions accountable for quality control; (iv) supporting new quality filtering standards for scientific journals and repositories, and (v) establishing a new network of centers for scientific health communications.

Petrograd (Leningrad) physical and mathematical society in 1921–1930: science management, publishing activities, and international relations

Drawing on the archival materials, the article examines the activities of the Petrograd (Leningrad) Physical and Mathematical Society in the 1920s, focusing on those concerned with research, science management, publishing and international relations. Despite its relatively short lifespan, the Society’s efforts proved to be very fruitful: regular meetings were held where scientific papers were presented and discussed, a dedicated scientific journal was published, and scientific links were maintained both domestically and internationally. Prominent Russian scientists took an active part in the Society’s activities, including Ya. V. Uspensky, V. I. Smirnov, B. N. Delone (Delaunay), G. M. Fikhtengol’ts (Fichtenholz), V. A. Steklov, A. A. Fridman (Friedmann), V. A. Fok (Fock), A. S. Besikovich, S. N. Bernshtein (Bernstein), Ya. D. Tamarkin, R. O. Kuzmin, N. I. Muskhelishvili, L. G. Loitsyansky, B. G. Galerkin. Society members attended international congresses and conferences, establishing and promoting important scientific contacts with foreign scientists and enhancing the worldwide authority of Soviet mathematicians and physicists. However, in 1930, the Society decided upon self-dissolution due to a number of reasons: introduction of new regulation aimed at the reorganization of scientific societies, the escalation of conflicts among the mathematical community, and the beginning of repressions against some mathematicians. Nevertheless the Petrograd (Leningrad) Physical and Mathematical Society had made a significant contribution to the advancement of physical and mathematical sciences in our country.

Environmental Factors to Malaria Incidence : A Literature Review

Malaria remains a major public health concern in Indonesia, particularly due to its high mortality rate among children under five, accounting for approximately two-thirds of all cases. The disease is transmitted by female Anopheles mosquitoes, which carry the Plasmodium parasite. In 2019, malaria caused 409,000 deaths globally, with 229 million cases reported, particularly in remote areas with poor access to healthcare, commonly in low-income countries. This literature review highlighted the environmental risk factors contributing to malaria incidence, based on studies from 24 scientific journals using data from the Sinta and Scopus databases. The study identified key environmental factors, including physical, chemical, biological, and socio-cultural elements, with the most significant risk linked to vector breeding sites. Among the reviewed articles, 62.5% (15 out of 24) found a statistically significant association between the presence of mosquito breeding sites and malaria incidence. Additional risk factors included the use of mosquito nets, housing conditions (specifically wall density), and nighttime outdoor activities. Effective malaria control measures require addressing these environmental factors, as they play a crucial role in the disease’s transmission. Strategies to disrupt the transmission cycle include eliminating mosquito breeding sites, applying larvicides to stagnant water, cleaning vector resting areas, promoting the use of insecticide-treated nets, and implementing Indoor Residual Spraying (IRS). A community-based, integrated approach to environmental management is essential to reducing malaria transmission and controlling its spread in affected regions.

University Dropout: A Systematic Review of the Main Determinant Factors(2020-2024).

This research is a systematic review aimed at synthesizing scientific evidence on the causes of university dropout, focusing on the subcategories of vocational guidance, academic performance, socioeconomic status, and institutional aspects between 2020 and June 2024. Only articles addressing university dropout were considered, analyzing dimensions such as vocational guidance, academic performance, socioeconomic status, and institutional aspects. Articles published in indexed scientific journals with double-blind, double-blind peer, or open reviews between 2020 and June 2024 were included. The main databases used were Scopus, Web of Science, and Google Scholar. To assess the risk of bias in qualitative studies, the criteria from the article "Validity criteria for qualitative research: three epistemological strands for the same purpose" were used. For quantitative studies, the criteria from the article "Evaluating survey research in articles published in Library Science journals" were followed. For mixed-method studies, both sets of criteria were combined. A total of 23 studies were included: 15 quantitative (65.22%), 3 qualitative (13.04%), and 5 mixed-method (21.74%). All studies (100%) addressed the subcategories of socioeconomic status and institutional aspects. Regarding the academic performance subcategory, 86% of the studies addressed it, while the vocational guidance subcategory was covered by 73.91% of the studies. Vocational guidance, academic performance, socioeconomic status, and institutional aspects are crucial for reducing university dropout. Providing adequate professional guidance, academic support, financial assistance, and strong institutional support is fundamental to improving student retention and academic success.

PREVENÇÃO DO ENVELHECIMENTO CUTÂNEO NA MENOPAUSA

Menopause, in the transition phase that generally occurs between the ages of 45 and 55, causes significant hormonal changes that affect a woman's physical and emotional health and quality of life. The reduction in hormones such as estrogen and progesterone especially impacts the skin, making it thinner, drier and less elastic, which facilitates the appearance of wrinkles and sagging. This process intensifies the search for aesthetic treatments aimed at revitalizing the skin and strengthening self-esteem. Among these interventions, radiofrequency (RF) and the use of dermocosmetics stand out, which stimulate fibroblasts and promote collagen production, being effective in facial, body and intimate rejuvenation. This study reviews scientific articles, dissertations, scientific journals, which were published between 2020 and 2024, with the aim of identifying treatments that prevent the signs of skin aging and promote skin health, seeking to offer effective aesthetic care alternatives for menopausal women.

Tradicals, Pillars and Directions For Educational Curriculum Development In Indonesia: A Literature Study

This paper aims to identify curriculum traditions, including curriculum changes from time to time in the history of Indonesian education, the five pillars of curriculum development as considerations in curriculum development, and to see the direction of curriculum development. The author used 17 references from scientific journals and books in this study. Tracking reference sources using Google Scholar. The study results show that the educational curriculum change is greatly influenced by political factors such as the change of government and the minister in charge of education, as well as by the shift in education policy. There are five pillars of curriculum development: curriculum objectives, content or materials, learning strategies, curriculum organization and evaluation. The current curriculum development direction focuses on technology integration through the Independent Curriculum platform. As for universities, they implement Independent Learning Independent Campus, which is expected to answer global challenges and prepare the generation to face an increasingly complex world.
