First-trimester pregnancy losses are commonly attributed to chromosomal abnormalities. The causes of pregnancy loss following transfer of a euploid embryo are not fully elucidated. The aim of this study was to evaluate clinical and embryological parameters for pregnancy failure following the transfer of a single euploid embryo. Pregnancy outcomes of single euploid embryo transfers from a single centre between January 2017 and March 2020 were retrospectively evaluated. Several clinical and embryological parameters were evaluated in consideration to pregnancy outcomes; total pregnancy loss and live birth (LB). Endometrial preparation type, number of previous frozen embryo transfer cycles, history of recurrent pregnancy loss, higher body mass index, presence of endometriosis and/or adenomyosis and embryo quality were found to be significantly different between two groups. Morphokinetic parameter analysis of 523 euploid embryos using time-lapse imaging did not show any statistical differences between the two groups; however, a significantly higher rate of uneven blastomeres in the cleavage stage was observed in the total pregnancy loss group. Evaluation of clinical and embryological data can reveal possible factors associated with pregnancy loss that can facilitate improved patient consultation. Feasible interventions can potentially increase the chance of achieving an LB.

Lay Abstract
Like natural pregnancies, not all pregnancies following fertility treatment go to term. The most common reason for these losses is that these embryos lack the genetic constitution compatible with live birth. Combined with fertility treatment, genetic tests can evaluate the genetic ability of embryos to go to term. Monitoring the outcome of pregnancies resulting from such embryos can help us identify whether and which conditions specific to treatment can lead to pregnancy loss. The analysis identified four parameters associated with embryo loss: Embryo quality and division patterns, existence of previous treatment and treatment type.

OBJECTIVE
To compare the efficacy (as measured by time to resolution of pain) and safety of valproate infusion and lidocaine infusion in the treatment of pediatric status migrainosus.

METHODS
We conducted a single-center retrospective cohort study from March 2014 to June 2021 evaluating children and adolescents who received a lidocaine or sodium valproate infusion for the treatment of status migrainosus. During the study period, lidocaine infusion was exclusively used before March 2016, whereas sodium valproate infusion was exclusively used afterward.

RESULTS
A total of 31 patients received lidocaine and 63 received sodium valproate infusion. Patients in the lidocaine group achieved significantly faster control of pain with median hours to pain free of 11.7 (interquartile range, 3.8–32.3) hours compared with 43.4 (interquartile range 13.8–68.7) hours in the valproate group (P = .002). At discharge, 21 of 31 (67.7%) of patients receiving lidocaine were pain-free compared with 26 of 59 (44.1%) of patients receiving valproate (P = .03). There were significantly more infusion interruptions of valproate compared with lidocaine for various patient-related factors (16/63, 25.4% vs 1/31, 3.2%; P = .009). More adverse effects were observed with valproate (42/63, 67%) compared with lidocaine (1/31, 3.2%; P &lt; .001). The significant difference in hours to pain control persisted after adjustment for sex, race, age, BMI, presence of comorbidities, and pain score at admission. All patients in both groups completed the infusions and were discharged from the hospital.

CONCLUSIONS
Intravenous lidocaine infusion is associated with superior pain control and a better safety profile compared with intravenous sodium valproate infusion in status migrainosus.

The loss of biodiversity and biotic homogenization are on the rise in ecosystems around the world as a result of species invasions, habitat degradation, and the effects of climate change. In the Sacramento–San Joaquin Delta, non-native species make up the majority of the fish community, and declines in native species have been well documented; however, little is known about whether these trends have resulted in biotic homogenization. In this study, we used data from a long-term beach seine survey to analyze regional beta diversity trends of nearshore fish assemblages in the Delta from 1995 to 2019. Overall, we found no evidence of regional biotic homogenization occurring over the study period. Regional beta diversity increased moderately over time and was significantly influenced by the high interannual variability of freshwater inflow. These beta diversity patterns were driven by the non-native Mississippi Silverside that has proliferated in the system in recent years, but also by a handful of native fish species such as the Sacramento Sucker, Tule Perch, and Splittail. Overall, our results offer a contrast to other highly invaded ecosystems around the world and suggest that despite the near extinction of some native fish species, there remain pockets of suitable habitat in the Delta that may play a key role in the conservation of remnant native fish diversity.

: Locally delivered anti-infective agents are one of the frequently used treatment strategies for the treatment of periodontal disease. Doxycycline (Doxy) is frequently preferred in periodontal therapy. Various carrier systems are available like Collagen sponges, mucoadhesive polymers. The use of PRF is a good strategy for drug delivery systems with its 3D matrix structure as a scaffold, as it can naturally degrade within a certain period of time without causing any allergic/inflammatory conditions in the body. Titanium platelet–rich fibrin (T-PRF) has a denser fibrin structure than PRF with long resorption time and may be a good candidate for long-term drug delivery and release.: To study and compare physical and antibacterial properties of T-PRF and Doxycycline loaded T-PRF.: It is an in vitro study. The T-PRF and T-PRF loaded with Doxycycline as T-PRF/Doxy was prepared and their physical properties like length and consistency was evaluated. Antibacterial activities against and will be investigated by measuring zone of inhibition after 24 hrs and 48 hrs.The antimicrobial activity of T-PRF against significantly increases after addition of doxycycline (p&#60;0.05) without significantly altering physical property of T-PRF.: T-PRF loaded with doxycycline can be used as local drug delivery agent. However, very little literature is available in this field. And in vivo studies are required to determine the efficiency in periodontitis and peri-implantitis cases.

: The position of maxillary impacted canine (MIC) and the presence of lateral incisor root resorption (RR) remains a challenge for interceptive orthodontics and surgical treatment planning. The use of panoramic radiographs will be compared with CBCT in the diagnosis of RR and emphasize the importance of accurate diagnostic imaging.: To compare the diagnostic accuracy of Cone Beam Computed Tomography and Panoramic Radiography in detecting lateral incisor RR associated with MIC. To evaluate, with respect to sector position of impacted canines, the agreement between panoramic radiographs and CBCT in detecting lateral incisor RR.: A cross-sectional retrospective descriptive study on panoramic and CBCT radiographic records between January 2014 and December 2020. The study setting was Section of Diagnostic Imaging at a University Oral Health Centre. All patients requiring radiographs are referred to this section by all dental departments of the dental hospital. The study sample consisted of CBCT and panoramic images of impacted maxillary canines of patients older than 9yrs. Patients with odontogenic and non-odontogenic pathology in the canine and incisor area, those with previous diagnosis of external root resorption verified from the patient’s treatment records, and patients who have had any form of orthodontic treatment; removable or fixed appliances were excluded. Data was analysed using Statistical Package for the Social Sciences (SPSS) version 27. Pearson's chi-squared test was used to analyse the agreement between panoramic radiographs and CBCT in locating canine sector position. All tests were conducted at 5% significance level. Fifty patients records were analysed in our study. The median age of the sample was 15 years and the IQR was 12.5-19. Our sample consisted predominantly of females (n=40) compared to males(n=10). A total of 65 MIC were assessed with 16 bilateral impactions (n=32) and the unilateral impactions (n=33). Of the 65 MICs, 46% were located on the right side and 54% were located on the left side. The CBCT examination showed that 58% (n = 38) of MIC were located palatally, 34% (n=22) labially and 8% (n=5) in the mid-alveolus (between the teeth). The majority of MIC occurred in sector 4 in 2-D pan (26%, n=17) and 3-D pan at (32%, n=21). Pearson's chi-squared test results showed a statistically significant difference in the agreement between 2-D pan and 3-D pan in locating canine sector position (p=0.001).: The detection of root resorption in our study underscores the importance for clinicians to examine panoramic radiographs thoroughly beyond the counting of teeth. Although panoramic radiographs are the routine diagnostic tool in contemporary dental practice, their limitation in definitive diagnosis of root resorption should be augmented with the use of CBCT.

Aim of this survey was to determine the communication the level of communication between dentists and dental laboratories in specific areas of the work authorization forms for the fabrication of fixed partial dentures. A questionnaire was prepared to assess communication gap between dentist and lab technicians through work authorization for FDPs. A total of 70 dental laboratory technicians were provided with a questionnaire regarding work authorization form via Google doc files. The survey focused questions pertaining to fulfilling the following areas of work authorization: patient’s information, name of the prescribing dentist, material for the prosthesis, pontic design of the prosthesis, shade description, and date of completion of work. The number of responses received was statistically evaluated using Fisher’s t‑test and nonparametric Spearman’s correlation coefficient (P ≤ 0.05). Eighty out of 100 laboratory technicians surveyed responded to the questionnaire.The patient’s general information was satisfactorily filled in 75%–100% of the forms. Information regarding the pontic design, staining diagram, and preferred margin were on the lower side of the scale ranging between 25% and 50%. The survey concluded that areas of work authorization with respect to fixed dental prosthesis require attention and need to be adequately filled by the dentist. In addition, the study suggests that the foundation of communication skill training programs in work authorization should be laid from the undergraduate curriculum. The concerned authorized bodies/specialty organizations should formulate a standardized work authorization format which can bridge the wide gap between the crown and bridge office and laboratory.

Aim: There is a dearth of information on in vitro oral bioaccessibility, challenging the evaluation of the health risks arising from indoor dust exposure to the brominated flame retardants, tetrabromobisphenol A (TBBPA), and hexabromocyclododecane (HBCDD). Here, we estimate the human oral bioaccessibility of TBBPA and HBCDD in indoor dust by applying the standardized bioaccessibility test under fasting (UBM-like test) and fed (FOREhST test) conditions.
Methods: In vitro bioaccessibility of HBCDD and TBBPA of sixteen indoor dust samples was conducted under fasted and fed states. In the fed test, food components, including healthy and unhealthy food. The concentrations of HBCDD and TBBPA were analyzed using LC-MS/MS. Bioaccessibility was calculated from the ratio of the amount of HBCDD and TBBPA in a simulated gut solution to that in indoor dust. The average daily dose (EDDbioaccessibility) was calculated from the estimated daily intake and percentage of bioaccessibility.
Results: The concentration of TBBPA and HBCDD in indoor dust ranged from 137 to 14,671 ng g-1 and < 0.7 to 528 ng g-1, respectively. A higher bioaccessible concentration was observed in the small intestine than in the stomach and mouth. The condition of the fed state with food containing fat showed greater bioaccessibility of TBBPA and HBCDD at 74.0% ± 9.5% and 62.2% ± 10.1%, respectively. In contrast, the fed state with lower fat food containing fiber presented the lowest bioaccessibility with a mean of 54.7% ± 10.7% for TBBPA and 53.7% ± 10.8% for HBCDD. Moreover, children are more exposed than adults, especially those who ingest indoor dust with fatty food.
Conclusion: The oral bioaccessibility of TBBPA and HBCDD in indoor dust was highest in the fed state with fatty food, followed by fasted and fed states with lower fat, higher fiber food. Similarly, the estimated daily dose (EDDbioaccessibility) for children exceeded that for adults. Therefore, this study indicated that food consumption is a factor influencing the bioaccessibility of TBBPA and HBCDD present in indoor dust.

: Leveraging the sustainability of the power system market, researchers have developed various ML models for forecasting electricity demand. The LSSVM is well suited to handle complex non-linear power load series. However, the less optimal regularization parameter and the Gaussian kernel function in the LSSVM model have contributed to flawed forecasting accuracy and random generalization ability. Thus, these parameters of LSSVM need to be chosen appropriately using intelligent optimization algorithms. This study proposes a hybrid model based on the LSSVM optimized by the IBFOA for forecasting the daily electricity load in Peninsular Malaysia. The IBFOA for parameter optimization of LSSVM is introduced. The IBFOA based on the sine cosine equation is proposed to adjust the constant step size in the BFOA, which creates an imbalance between the exploration and exploitation during optimization. Finally, the load forecasting model based on LSSVM-IBFOA is constructed using MAPE as the objective function. Comparative analysis demonstrates the model, achieving the highest R2 (0.9880) and significantly reducing error metrics (MAPE, MAE, RMSE, MSE, NRMSE) compared to the baseline LSSVM (average reduction of 27.72% to 47.72%). Additionally, IBFOA exhibits faster convergence and higher accuracy compared to BFOA, highlighting the accuracy of LSSVM-IBFOA for short-term load forecasting.

Abstract

Objectives/ Background The primary objective of this study is to histologically evaluate new bone formation in the time frame of 12 to 14 weeks as opposed to a generally considered 16 to 20 weeks after extraction of teeth with ridge preservation using DFDBA and T-PRF membrane and secondarily to evaluate the dimensional changes including ridge width and height at these healing points. (Clinical and biometric evaluation). Materials & method: The protocol of this study has been registered in clinical trial registry (Registration number: CTRI/2021/12/038608). With the present single arm longitudinal pilot investigation including nine patients, 6 males and 3 females aged 18 to 50 years (mean 28.25 ± 6.5) requiring teeth extraction and delayed implant placement were selected to receive atraumatic extraction followed by simultaneous ridge preservation using T-PRF and DFDBA with T-PRF as biologic membrane. Results: Baseline values concerning the investigated parameters were comparable at the stipulated healing outcome period. After 12 to 14 weeks, there was no significant difference observed in alveolar ridge dimension. DFDBA & T-PRF combination revealed significantly greater vital bone formation. Investigation revealed no residual graft particles. On confirmation of achieved bone density through CBCT analysis; all implants were successfully placed at 12 to 14 weeks. Conclusion: When practiced, alveolar ridge preservation using DFDBA & T-PRF combination favours reduction in time for biologic basis of bone healing thus facilitating early implant placement to improve patient centred outcomes.

Abstract

The IEEE standard IEEE 802.15.7, Li-Fi is a technology that provides rapid connection by using visible light communication (VLC). This technology is equivalent to Wi-Fi in terms of its speed. There is a connection between the IEEE 802.11 standard for wireless communication and the IEEE 802.15.7 standard for wireless communication technology. High-speed, bidirectional, and completely networked capabilities are some of the distinguishing features of this technology. Li-Fi is the most cutting-edge technology that has ever been developed. Within the context of vehicle-to-vehicle communication, this initiative is succinct in order to prevent accidents. In order to determine the distances between the front cars and to determine the amount of vibration that is present in the vehicles, the ultrasonic sensor is used. This information is sent to the receiving car via the Li-Fi transmitter once the gas sensor has determined the amount of alcohol that the driver is under the influence of. In the event that the front car is experiencing any kind of abnormal situation, this vehicle will come to a halt on the second. The microcontroller's UART function is coupled to the Li-Fi component of the system. One kind of communication technology is called Light Fidelity, or Li-Fi for short. This technology makes use of light as a channel. The technology in question is known as visible light communication (VLC), and it eliminates the complexities associated with cable network connectivity. The evolution of Li-Fi over the last several years has shown that it is not only safe and effective, but also capable of transmitting data at very fast rates. Within the scope of this work, a communication system is described that uses light as a medium to regulate the speeds of two motors in order to communicate data from a transmitter to a receiver.
