A CBCT Assessment of Orthodontic Mini-Implant Placement

ABSTRACT Objectives: This study compares the precision of cone beam computed tomography (CBCT) and two-dimensional radiography for mini-implant implantation. Materials and Method: For 30 sites (in 15 patients between the ages of 13 and 26 years), the buccal interradicular region among the 2nd premolar and 1st molar was found to be the best location for mini-implants. Next, two groups of the mini-implant implantation process were created. Mini-implants were positioned at the CBCT data-identified sites in the CBCT group. Mini-implants were inserted in the RVG group by using two-dimensional digital radiography and a specially constructed guide. To assess the precision of the mini-implant implantation, post-placement CBCT images were acquired. The obtained data were statistically analyzed. Result: The two groups showed a statistically considerable variation in the mini-implant placement’s departure from the optimal height. Due to the smaller interradicular space and decreased convenience in the posterior mandibular area, two out of 15 mini-implants in the RVG group demonstrated root contact in the mandibular jaw Conclusion: The two-dimensional intraoral radiograph of the interradicular area provides sufficient information for mini-implant placement even though CBCT accurately visualizes the interradicular space in three dimensions.

Этические аспекты, проблемы безопасности кардиохирургического вмешательства и предикция неблагоприятных событий

In cardiac surgery, patient’s awareness and consent to surgery are problematic as due to the lack of previous medical background a patient can’t understand the processes occurring in the body and effects of exposure on them. Thus, provision of sufficient information by a doctor is a part of safe surgical strategy. An open randomized prospective trial involving 89 patients with stable coronary artery disease (CAD) was conducted. High rate of blood oxidation is believed to be an independent predictor of cognitive dysfunction development during the early postoperative period of coronary artery bypass grafting (CABG). Determination of blood oxidation rate is a tool of risk management during cardiac surgery starting from the stage of preoperative preparation, which is optimal to implement a safe strategy, including psychological and drug-induced support of the patient aimed at prevention of cognitive disturbances.

Molecular detection and identification of Plasmodium spp. isolated from captive-bred cynomolgus monkeys in Bogor, Indonesia

Background and Aim: Asian macaques are natural hosts of several Plasmodium species. Some monkey malaria parasites may infect humans and cause zoonotic infections. This study was conducted to estimate the prevalence of monkey malaria parasites in Bogor, Indonesia, based on molecular detection and identification, particularly in cynomolgus monkeys, which have a wide geographic distribution and share extensive habitats with humans. These data are needed to evaluate the status of simian malaria among macaques in Bogor and to study the potential risks to human health. These updated data will provide sufficient information for implementing malaria control strategies in the future and for developing a potential malaria vaccine using monkeys as an animal model. Materials and Methods: Blood samples of 274 cynomolgus monkeys (Macaca fascicularis) were collected and identified using microscopy. DNA was extracted from positive blood samples and analyzed using polymerase chain reaction (PCR) to amplify the small subunit ribosomal RNA (SSU rRNA) target gene using consensus primers for Plasmodium species. The PCR-positive samples were then nucleotide-sequenced using commercial sequencing services, analyzed using the BioEdit program, and aligned using Basic Local Alignment Search Tool from the National Center for Biotechnology Information. Phylogenetic trees were constructed using MEGA 11.0 and the neighbor-joining (NJ) method to determine the kinship of Plasmodium. Bootstrapping was performed using 500 replicates to assess the robustness of tree topologies. Results: Thirty-eight of the 274 microscopically positive samples for Plasmodium spp. were also positive using PCR, resulting in a 1640 bp amplicon. Further, analysis using nucleotide sequencing confirmed that these positive samples were Plasmodium inui with more than 99% nucleotide identity compared to GenBank sequences. Phylogenetic tree analysis of the SSU rRNA partial gene showed that all our isolates clustered and were closely related to a P. inui strain isolated from cynomolgus macaques in South China in 2011. Conclusion: P. inui is the predominant malaria parasite in cynomolgus monkeys from Bogor. Keywords: malaria, phylogenetic tree, Plasmodium inui, small subunit ribosomal RNA.

Shared decision making in older people after severe stroke.

Stroke is a major cause of death and lifelong disability. Although stroke treatments have improved, many patients are left with life-changing deficits. Shared decision making and consent are fundamental to good medical practice. This is challenging because stroke often causes mental incapacity, prior views might not be known and prognosis early after stroke is often uncertain. There are no large trials of shared decision making after severe stroke, so we need to rely on observational data to inform practice. Core ethical principles of autonomy, beneficence, non-maleficence and justice must underpin our decision making. 'Surrogate' decision makers will need to be involved if a patient lacks capacity, and prior expressed views and values and beliefs need to be taken into account in decision making. Patients and surrogates often feel shocked at the sudden nature of stroke, and experience grief including anticipatory grief. Health care professionals need to acknowledge these feelings and provide support, be clear about what decisions need to be made and provide sufficient information about the stroke, and the risks and benefits of treatments being considered. Shared decision making can be emotionally difficult for health care professionals and so working in a supportive environment with compassionate leadership is important. Further research is needed to better understand the nature of grief and what sort of psychological support would be most helpful. Large randomised trials of shared decision making are also needed.

Application of Big Data Technology in Audit

In the new era of rapid development of big data technology, the three key points of high-quality development of auditing are auditing talents, auditing rule of law and auditing technology. In the traditional audit process, auditors focus on professional judgment and professional competence, make audit plans, implement audit procedures and draw audit conclusions. However, there are many problems in traditional audit work, such as difficulty in obtaining sufficient external information and inefficiency in analyzing audit evidence. Therefore, auditors apply big data technology to audit work to solve various problems and put forward corresponding safeguard measures.

Comparing five equations to estimate glomerular filtration rate or creatinine clearance and assign individuals to KDIGO categories across the full age spectrum using real world data

AbstractFive equations are commonly used by biopharma companies to estimate glomerular filtration rate (GFR) or creatinine clearance (CrCl) based on regulatory and stakeholder recommendations. Changes observed in GFR and/or CrCl can be challenging to interpret as participants transition between age strata, prompting changes in equations. This manuscript explores how GFR, CrCl, and the resulting Kidney Disease Improving Global Outcomes (KDIGO) categories of kidney function can change when different equations are used. We analyzed descriptively real‐world data (RWD) from 48 health care organizations in the United States to identify patients with data (age, sex, height, weight, serum biomarkers such as creatinine [Scr] and/or cystatin C [Scys]) sufficient to estimate GFR and/or CrCl. Five equations (Bedside Schwartz, Modified Schwartz, Cockcroft‐Gault, 2021 Chronic Kidney Disease‐Epidemiology Collaboration [CKD‐EPI] Scr, and 2021 CKD‐EPI Scr/Scys) were used to estimate GFR and/or CrCl and assign individuals to KDIGO categories (G1–G5). We identified 32,728 patients, including 378 infants (<2 years), 1191 younger children (2 to <6 years), 1891 older children (6 to <12 years), 3174 adolescents (12 to <18 years), 16,367 younger adults (18 to <65 years), and 9727 older adults (65+ years) with sufficient information to estimate kidney function. For patients greater than or equal to 2 years, estimated GFR and/or CrCl and KDIGO categories based on the 2021 CKD‐EPI Scr/Scys equation appeared similar to those based on currently recommended equations. RWD suggests the 2021 CKD‐EPI Scr/Scys equation could potentially be used to estimate GFR in individuals aged 2 years and older; more research is needed to confirm these findings.

Indicators for measuring and reporting corporate nature-related impacts, dependencies, and risks

Businesses are embedded within nature. Their supply chains, operations, and products fundamentally depend on and impact nature. These impacts and dependencies can give rise to nature-related risks (as well as related opportunities). However, despite growing expectations from stakeholders, most businesses are currently not adequately measuring and reporting on these. To date, it has not been clear whether this requires the development of entirely new indicators, or whether various existing sustainability reporting frameworks could provide sufficient information on nature-related risks. This paper evaluates the decision-usefulness of existing indicators for the softwood plantation forestry industry in Australia. Decision-usefulness is assessed against three criteria: (1) relevance and completeness; (2) faithful representation; and (3) comparability. The results show some potential for adaptation of indicators already used in sustainability-related corporate accounting and reporting, which could help reduce the reporting burden and encourage uptake. However, gaps remain in measuring the financial consequences for business from nature-related risks and in providing sufficient comparable information to evaluate performance across industries and locations. Implications are discussed in relation to recent recommendations from the Taskforce on Nature-related Financial Disclosures (TNFD) and International Sustainability Standards Board (ISSB) sustainability standards IFRS S1 and S2.

YOLO-Rlepose: Improved YOLO Based on Swin Transformer and Rle-Oks Loss for Multi-Person Pose Estimation

In recent years, there has been significant progress in human pose estimation, fueled by the widespread adoption of deep convolutional neural networks. However, despite these advancements, multi-person 2D pose estimation still remains highly challenging due to factors such as occlusion, noise, and non-rigid body movements. Currently, most multi-person pose estimation approaches handle joint localization and association separately. This study proposes a direct regression-based method to estimate the 2D human pose from a single image. The authors name this network YOLO-Rlepose. Compared to traditional methods, YOLO-Rlepose leverages Transformer models to better capture global dependencies between image feature blocks and preserves sufficient spatial information for keypoint detection through a multi-head self-attention mechanism. To further improve the accuracy of the YOLO-Rlepose model, this paper proposes the following enhancements. Firstly, this study introduces the C3 Module with Swin Transformer (C3STR). This module builds upon the C3 module in You Only Look Once (YOLO) by incorporating a Swin Transformer branch, enhancing the YOLO-Rlepose model’s ability to capture global information and rich contextual information. Next, a novel loss function named Rle-Oks loss is proposed. The loss function facilitates the training process by learning the distributional changes through Residual Log-likelihood Estimation. To assign different weights based on the importance of different keypoints in the human body, this study introduces a weight coefficient into the loss function. The experiments proved the efficiency of the proposed YOLO-Rlepose model. On the COCO dataset, the model outperforms the previous SOTA method by 2.11% in AP.

Fertility-Related Conversations in the Context of COVID-19 and Vaccinations.

We used text analysis to examine trends and self-reporting in Twitter regarding COVID-19 disease and COVID-19 vaccines' effects on fertility. Trends and self-reporting related to COVID19 vaccines indicates that further research is needed to enable women to feel they have sufficient information to make decisions regarding vaccination, together with social listening and engagement with women's concerns regarding vaccination effects.

DOP37 Noninvasive assessment of gut function using transcriptional recording sentinel cells

Abstract Background Bacteria within the human gut continuously adapt their gene expression to environmental conditions that are associated with diet, health, and disease. Noninvasive measurements of bacterial gene expression patterns throughout the intestine are important to understand in vivo microbiota physiology and pathophysiology. Current methods do not offer sufficient information about transient or proximal events within the intestine without using indirect or invasive approaches that disturb normal physiology and are inapplicable to clinical practice. Methods Here we used transcriptional recording sentinel cells that through a reverse transcriptase-Cas1–Cas2 complex record their own short-lived mRNA expression into long-lived DNA-based CRISPR arrays to report on gut function. We colonized gnotobiotic mice with E. coli sentinel cells and performed Record-seq on fecal samples to reconstruct their cellular histories as they passed along the gastrointestinal tract. Results Upon colonization of the mouse intestine, sentinel cells reported on diet, inflammation, and microbial interactions. Through transcriptome-scale information, Record-seq elucidated E. coli’s adaptations to intraluminal conditions including pH, oxygen levels, and ion availability. Unlike RNA-seq, Record-seq performed on stool samples retained information from proximal gut sections to noninvasively report on the luminal conditions in vivo. In a mouse model of inflammatory bowel disease, Record-seq not only diagnosed the inflammation in a severity-dependent manner but also revealed pathological gut conditions such as mucus depletion and hyperoxygenation. Conclusion Transcriptional recording sentinel cells noninvasively report on gut function and reveal environmental cues such as diet, inflammation, and microbial interactions, even in proximal gut sections that are otherwise unamenable to unbiased diagnostic interrogation.

Self-Adaptive Forensic-Based Investigation Algorithm with Dynamic Population for Solving Constraint Optimization Problems

The Forensic-Based Investigation (FBI) algorithm is a novel metaheuristic algorithm. Many researches have shown that FBI is a promising algorithm due to two specific population types. However, there is no sufficient information exchange between these two population types in the original FBI algorithm. Therefore, FBI suffers from many problems. This paper incorporates a novel self-adaptive population control strategy into FBI algorithm to adjust parameters based on the fitness transformation from the previous iteration, named SaFBI. In addition to the self-adaptive mechanism, our proposed SaFBI refers to a novel updating operator to further improve the robustness and effectiveness of the algorithm. To prove the availability of the proposed algorithm, we select 51 CEC benchmark functions and two well-known engineering problems to verify the performance of SaFBI. Experimental and statistical results manifest that the proposed SaFBI algorithm performs superiorly compared to some state-of-the-art algorithms.

Why does OCR only post determinations of violations to its reading room?

The Office for Civil Rights has long assisted institutions and the general public in understanding Section 504 compliance obligations by posting to its reading room selected determination letters and resolution agreements arising from Section 504 complaints and investigations, indexed and sorted by issues, parties, and dates for easy searching (https://bit.ly/3NP5zjI). Although determination letters also can be obtained in redacted form through a Freedom of Information Act Request, requesting an individual letter requires knowing its relevance and sufficient descriptive information to identify it, so in the absence of prior knowledge of a specific investigation, the reading room is the only publicly available resource from which one can readily to obtain determination letters.

Local geometric edge features based registration for textureless object in augmented reality assisted assembly

Image-based methods have been widely used in augmented reality (AR) assistant assembly systems. However, due to the lack of sufficient texture information on the surface of assembly part, traditional image feature matching methods still face challenges. This paper proposes a coarse-to-fine AR registration method for textureless assembly part. In the first stage, a new feature matching method which is called line neighborhood edge descriptor (LNED) is presented to find the coarse camera pose from textureless image. The LNED take the contour line of assembly part as the description object, and use local geometric edge of assembly part to describe the contour line. During the image matching, the binary encoding is used to reduce the computational consumption for LNED. In the second stage, spatial points in the CAD model of assembly part are reverse projected to the textureless image based on the coarse camera pose. And the bundle adjustment method based on the edge distance of the textureless image is adopted to iteratively calculate the precise camera pose. In the experimental evaluation, the proposed registration method shows high accuracy and fast speed in comparison with conventional registration methods, which demonstrates that our method can effectively solve the problem of AR registration for textureless assembly part.

Real-World Use of Ruxolitinib Cream: Safety Analysis at 1 Year.

Ruxolitinib cream is the first topical Janus kinase (JAK) inhibitor approved in the United States (US) for the treatment of mild to moderate atopic dermatitis and nonsegmental vitiligo. A postmarketing study with oral tofacitinib, approved for rheumatoid arthritis, triggered class warnings for JAK inhibitors, including risk of serious infections, mortality, malignancy, major adverse cardiovascular events, and thrombosis. Because ruxolitinib cream is indicated for inflammatory conditions, it is subject to the same warnings as oral JAK inhibitors in the US. Here, nearly 14,000 patient-years of postmarketing safety data from the first year following market approval of ruxolitinib cream were reviewed. The Incyte global safety database(21 September 2021-20 September 2022) and US FDA Adverse Event Reporting System (as of 30 September 2022)were queried for adverse event (AE) reports received for ruxolitinib cream. The search identified 294 postmarketing individual case safety reports containing 589 events, including four serious AEs and no fatal AEs. AEs (i.e., any unfavorable sign, symptom, or disease) representing >2% of all events included application site pain (n=16), atopic dermatitis (n=15), skin irritation (n=15), scratch (n=14), and condition aggravated (n=13). The four serious AEs were skin cancer (n=2), pericarditis, and thrombocytopenia (both n=1), none of which had sufficient information to assess possible relatedness to ruxolitinib cream. Serious AEs associated with the class warnings for JAK inhibitors were not reported. Postmarketing safety data from the year following approval suggest ruxolitinib cream is generally well tolerated, without significant systemic AEs, and with a low incidence of application site reactions.

The role of electronic leaflets in improving access to medication-related information

Background: Language discrepancies may create barriers to healthcare, compromise the quality of care and worsen health outcomes. This study explored what European countries currently do to ensure that foreign patients receive sufficient information about their medications if they do not understand the country’s national language. Methods: A questionnaire was distributed to the delegates of two Council of Europe committees. The recipients were asked to provide insights on how their country facilitates access to the necessary product information when patients do not understand the national language. Results: Seventeen out of 39 delegates completed the questionnaire. The majority of the respondents indicated that all healthcare professionals experience difficulties in providing guidance and advice to foreign patients. The results also showed that different methods are used nationally to present the necessary information to foreigners. Finally, the observations from this survey suggested that electronic leaflets in the patient’s primary language could be a valuable option to improve access to medication-related information. Conclusions: Healthcare professionals seem to encounter challenges in providing foreign patients with information associated with medication use. Electronic leaflets can be one of the tools for improving communication between these patients and healthcare professionals to ensure that medicines are used safely and effectively.

Moving actuator surfaces: a new concept for wind turbine aerodynamic analysis

The actuator disk is a concept often used in wind turbine aerodynamics, where the action of the turbine on the flow is averaged over time and space. This simplification stills retain sufficient physical information for wind turbine aerodynamic design. Its limitations are essentially related to the impossibility to model the blade shed vorticity. This paper presents a more general approach that uses rotating actuator surfaces carrying velocity and pressure discontinuities which are set from knowledge of the circulation around the model blade sections and using blade element analysis. The mathematics of rotating actuator surfaces, as well as an application to the TUDelft rotor are presented in this paper. The results are encouraging.

Effects of Health Records Management on Health Service Delivery: A case study of the Prestea Government Hospital. (PGH)

Background: The most crucial instrument when discussing patient healthcare are medical records. Both their management and their utilization are crucial for patient care management. Ghana has used many medical records management systems to aid in healthcare development. Retrospective and epidemiological investigations are slowed down by poor data quality, which inhibits research. As expectations have grown, more initiatives to capture and save patient records electronically are planned. Aim: The purpose of the study is to investigate the perception of health worker about the EHRs use and impact on service delivery. Materials and methods: The study's focus is on the health workers at Prestea Government Hospital (PGH), which include nurses, physicians, biotechnologists, Health Information Manager, pharmacists, midwives, etc. A sample size of 100 people from the intended audience was used. Standardized questionnaires were self-completed by respondent. The Completed questionnaires were given numbers to protect participants anonymity. Participants received sufficient information regarding their right to decline study participation and to withdraw at any time without repercussions. Data was entered into Excel and exported to SPSS for analysis. Descriptive and inferential analysis was performed and the outcomes were shown as tables, graphs, and figures. Results: In all, out of 100 respondents, 35% of them were males and 65% were women. There were a lot of female replies since many of the respondents were nurses. Medical laboratory technicians comprised the smallest proportion of the workforce (5%) of all occupational groups. Prestea Government Hospital survey respondents overwhelmingly concur that electronic health records (EHRs) aid in the delivery of treatment. According to a survey, medical practitioners think the facility's EHR has all of the forms that are utilized there. The idea that the facility's EHRs help with data collection is accepted by few people. Medical professionals believe that the use of EHRs makes it simple to obtain historical patient data. This is so that all information may be easily accessed while undergoing medical treatment and kept securely saved. The system features alarms that play when erroneous data is entered. Although the system features pre-programmed commands that allow for uninterrupted navigation, there are frequently disruptions due to power fluctuations. Conclusion: Access to patients' medical records via an electronic health information system platform is crucial for making medical decisions that will result in effective care delivery in healthcare facilities, lower the risk of treatment errors, decrease patient waiting times, and lower the number of medical errors, a study has found.

Use of Hydroacoustic Methods to Assess Ecological Status Based on Fish: A Case Study of Lake Dejguny (Poland)

The idea of the article was to verify the thesis that acoustic studies of ichthyofauna in lakes provide sufficient information to determine the necessity (or lack thereof) of carrying out a full procedure for assessing the ecological status based on fish. The manuscript compares acoustic data collected in 2008 and 2021 in Lake Dejguny (Poland) as a result of acquisition carried out with the same EY-500 echosounder, on the same routes (transects), and the echogram analyses were carried out using software dedicated to this echosounder. Target strength (TS) distribution was determined in the lake and in individual water layers with a thickness of 2 m, as well as, using the mapping method, changes in the distribution of fish in selected water layers. Large changes in TS distribution in the vertical profile were demonstrated between both years of the study, as well as a clear reduction in the space available for fish in waters below 24 m in 2021, which was associated with a reduction in the concentration of dissolved oxygen below this depth to a value lower than 2.5 mg L−1. It was suggested that it could be possible to develop a simple index enabling the assessment of changes in fish structure, based, similarly to the Large Fish Index, on the ratio of the number of large fish to small fish. The obtained results confirmed that the proposed methods of acoustic data analysis can be the basis for the decision on the necessity (or lack thereof) of conducting an assessment using the Polish national LFI-EN method based on the results of one-off fishing with Nordic multimesh gillnets.

Microplastic pollution in urban stormwater inlet sediments influenced by land use type of runoff drainage area

Since the urban stormwater inlet (USI) acts as a link in the migration of microplastics (MPs) in stormwater, sufficient information on MPs in USI sediments is very important for understanding urban diffuse microplastic pollution. In this study, the abundance and characteristics of MPs in the USI sediments of Ma'anshan City, China, were analyzed based on urban land use type. MPs were prevalent in the USI sediments, with the average abundances of 536.77 ± 313.92 items·kg−1 for commercial areas, 505.64 ± 400.82 items·kg−1 for campuses, 694.71 ± 219.95 items·kg−1 for industrial areas, 526.41 ± 152.34 items·kg−1 for residential areas, and 1107.75 ± 422.10 items·kg−1 for main roads, indicating a high microplastic pollution in the USI sediments from main roads. The microplastic polymers were mainly polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), and polystyrene (PS), accounting for 46.75 %–100.00 %, with PP MPs being the most abundant. Fiber MPs had the highest proportion in USI sediments from both campuses (35.30 %) and industrial areas (38.19 %), while film MPs were the most abundant for both commercial areas (39.91 %) and residential areas (35.65 %). The average proportions of fiber (27.29 %), fragment (29.18 %), and film (28.68 %) were almost equal for main roads, unlike other land use types. Except for campuses, transparent MPs were the most common for all land use types, with average proportions of 29.60 %–42.70 %. The proportions of MPs with sizes of <1000 μm were 72.54 % for commercial areas, 77.11 % for campuses, 76.05 % for industrial areas, 70.76 % for residential areas, and 74.29 % for main roads, respectively, with a consistent result with previous study that the MPs of <1000 μm are the predominant in the environment. This study enriches the knowledge of microplastic pollution in USI sediments and will benefit the mitigation of diffuse microplastic pollution.
