Background: Left bundle area branch pacing (LBBP) is a novel conduction system pacing method to achieve effective physiological pacing and an alternative to cardiac resynchronization therapy (CRT) with biventricular pacing (BVP) for patients with heart failure and reduced ejection fraction (HFrEF). Objective: To review current data comparing BVP and LBBP in patients with HFrEF and indication CRT. Methods: We searched PubMed/Medline, Web of Science, and Cochrane Library from the inception of the database to November 2022. All studies that compared LBBP with BVP in patients with HFrEF and indications of CRT were included. Two reviewers performed the study selection, data abstraction, and risk of bias assessment. We calculated risk ratios with the Mantel-Haenszel method and mean difference with inverse variance using random effect models. We assessed heterogeneity using the I 2 index, with I 2 > 50% indicating significant heterogeneity. Results: Ten studies (9 observational studies and 1 randomized controlled trial; 616 patients; 15 centers) published between 2020 and 2022 were included. We observed a shorter fluoroscopy time [mean difference (MD) 9.68, 95% CI 4.49-14.87, I 2=95%, P<0.01, minutes] as well as a shorter procedure time (MD 33.68, 95% CI 17.80-49.55, I 2=73%, P<0.01, minutes) during implantation of LBBP CRT compared to conventional BVP CRT. LBBP was shown to have a greater reduction in QRSd (MD 25.13, 95%CI 20.06-30.20, I 2= 51%, P<0.01, milliseconds) a greater left ventricular ejection fraction (LVEF) improvement (MD 5.80, 95% CI 4.81-6.78, I 2=0%, P<0.01, percentage) and a greater ventricular end-diastolic diameter (LVEDD) reduction (MD 2.11, 95% CI 0.12-4.10, I 2=18%, P=0.04, millimeter). There was a greater improvement in New York Heart Association function (NYHA) class with LBBP (MD 0.37, 95% CI 0.05-0.68, I 2=61%, P=0.02).LBBP was also associated with a lower risk of a composite of heart failure hospitalizations and all-cause mortality [Risk ratio (RR) 0.48, 95% CI 0.25-0.90, I 2=0%, p=0.02] driven by reduced heart failure hospitalizations (RR 0.39, 95% CI 0.19-0.82, I 2=0%, p=0.01). However, all-cause mortality rates were low in both groups (1.52% vs. 1.13%) and similar (RR 0.98, 95%CI 0.21-4.68, I 2=0%, p=0.87). Conclusion: Compared to BVP, LBBP is associated with, a greater improvement in LV systolic function, and a lower rate of heart failure-related hospitalization. Dedicated randomized controlled trials and larger patient populations are needed to further elucidate the long-term safety and efficacy of LBBP CRT.

In the production of biopharmaceuticals depth filters followed by sterile filters are often employed to remove residual cell debris present in the feed stream. In the back drop of a global pandemic, supply chains associated with the production of biopharmaceuticals have been constrained. These constraints have limited the available amount of depth filters for the manufacture of biologics. This has placed manufacturing facilities in a difficult position having to choose between running processes with reduced number of depth filters and risking a failed batch or the prospect of plants going into temporary shutdown until the depth filter resources are replenished. This communication describes a modeling based method that leverages manufacturing scale filtration data to predict the depth filter performance with a reduced number of filters and an increased operational flux. This method can be used to quantify the acceptable level of area reduction before which the filtration process performance is affected. This enables facilities to manage their filter inventory avoiding potential plant shutdowns and reduces the risks of negative depth filter performance.

Prediction of solar output power is a valuable research work for analyzing photovoltaic(PV) power. This study develops a futuristic deep-learning algorithm that predicts solar power output. The solar output data is collected in real-time for a series-parallel combination of PV systems with a 1 KW capacity that is available in our laboratory. The collected data is pre-processed via, initialization, normalization, and validation for accurate prediction. The normalization process is used to create the data set needed to fill in the missing values. The k-nearest neighbor (KNN) algorithm and the interpolation method are used to fill in the missing value. Then, the data is validated using a newly proposed deep long short-term memory (DLSTM) algorithm for solar output power prediction. Also as a new approach, the DLSTM algorithm and a recurrent neural network (RNN) are combined with the capture of time-series data in the validation process to improve the prediction accuracy. To prove its superiority, the proposed DLSTM-RNN model is compared with other exciting models, like the artificial neural network (ANN), long-short-term memory (LSTM), and recurrent neural network (RNN). All the models are trained and tested using three different activation functions viz Sigmoid, ReLU, and tanh with different epoch values. Finally, the accuracy is evaluated in terms of different performance error indexes, such as the basic error index (BEI) and the promoting percentage error index (PPEI).

Bushfire fuel hazard is determined by fuel hazard that represents the type, amount, density, and three-dimensional distribution of plant biomass and litter. The fuel hazard represents a biological control on fire danger and may change in future with plant growth patterns. Rising atmospheric CO2 concentration (Ca) tends to increase plant productivity (‘fertilisation effect’) but also alters climate, leading to a ‘climatic effect’. Both effects will impact on future vegetation and thus fuel hazard. Quantifying these effects is an important component of predicting future fire regimes and evaluating fire management options. Here, by combining a machine learning algorithm that incorporates the power of large fine-resolution datasets with a novel optimality model that accounts for the climatic and fertilisation effects on vegetation cover, we developed a random forest model to predict fuel hazard at fine spatial resolution across the state of Victoria in Australia. We fitted and evaluated model performance with long-term (i.e., 20 years), ground-based fuel observations. The model achieved strong agreement with observations across the fuel hazard range (accuracy >65%). We found fuel hazard increased more in dry environments to future climate and Ca. The contribution of the ‘fertilisation effect’ to future fuel hazard varied spatially by up to 12%. The predictions of future fuel hazard are directly useful to inform fire mitigation policies and as a reference for climate model projections to account for fire impacts.

A 2-year-old racing Thoroughbred gelding in training was presented with moderate (6/10) right hindlimb lameness unresponsive to regional anaesthesia of the right hind limb. Gamma scintigraphic examination revealed severe, focal, increased radio-pharmaceutical uptake over the dorsal aspect of the right 18th rib, which had an abnormal contour. Ultrasonographic examination of this area confirmed the presence of a complete, displaced fracture of the proximal aspect of the right 18th rib. Local infiltration with local anaesthetic around the 18th right rib (10ml cranial and 10ml caudal to the fracture site) abolished the right hindlimb lameness. A diagnosis of rib fracture causing moderate ipsilateral hindlimb lameness was made. The horse returned to walking exercise after 12 weeks of rest and was reported to be sound on the same limb 12 months after presentation. Caudal rib fractures should be considered as possible cause of hind limb lameness. Local diagnostic anaesthesia around the fracture site can aid localise the origin of lameness.

Objective: The risk of postoperative cognitive dysfunction in elderly patients is high, affecting work and life, and the quality of life is decreased to some extent. However, there is an urgent need to discover a new therapeutic target drug to prevent POCD occurrence. Galantamine, a cholinesterase inhibitor, can reduce apoptosis and relieve POCD by inhibiting endoplasmic reticulum stress. Our study will investigate the mechanism of galantamine on isoflurane induced POCD in aged mice. Methods: The aim of this study was to construct a POCD model of aged mice, test the effects of isoflurane on learning and memory of aged mice by using Y maze and open field equipment, and then analyze the apoptosis rate of hippocampal CA1 neurons by TUNEL method. The mRNA and protein expressions of GRP78, ATF4 and CHOP were determined by RT-qPCR and Western-Blot. Through experimental analysis, this study also obtained the optimal dose of galantamine in the treatment of POCD. Results: Our experimental results showed that after isoflurane anesthesia, the cognitive function of aged mice was significantly impaired, the neuronal cells in the hippocampus were seriously apoptotic, and GRP78, ATF4 and CHOP were upregulated. It is worth noting that our study confirmed that galantamine saved neuronal cell apoptosis in aged mice and drastically down-regulated GRP78, ATF4 and CHOP, which is expected to be a new pharmacological target for the treatment of POCD. Interpretation: Galanthamine is a drug with wide application space in the field of postoperative cognitive impairment research. This study explores pharmacological targets for improving cognitive dysfunction

Background: Patient information leaflets (PILs) have proven to be a good source of information to prescribers, dispensers, and patients by providing important information about the proper use and handling of medicines. This study aimed to evaluate the conformance of the patient information leaflet of selected innovator and generic medicinal products to Ethiopian regulatory requirements. Method: A descriptive cross-sectional study design and stratified sampling technique were applied to collect product information leaflets from each pharmacological category of medicinal products. Result: Most of the PILs studied (96.4–99.6%) showed a high rate of conformance concerning nine parameters. However, the least percentage conformance (24.3–48.6%) was observed for the inclusion of product information regarding four parameters. Regulatory conformance of the innovator/comparator products in almost all of the parameters but clinical pharmacology of medicines was found to be higher than those of their generic counterparts. The European-manufactured medicines showed relatively higher conformance across parameters compared to Asian and African manufactured ones. Program drugs revealed better conformance than other classes of medicines in most parameters. Conclusion: The findings of this study indicated that, despite the efforts taken by the concerned body to establish a minimum regulatory framework to ensure the safety, quality, and efficacy of medicines, an indicative number of commercial packs of medicinal products in Ethiopia do not fulfill all the necessary information requirements set by the authority. Hence, the Ethiopian Food and Drug Authority (EFDA) should take maximum efforts to undertake intensive evaluation during pre-market authorization to ensure that commercial packs of medical products are accompanied by complete product information.

In this work, a modified polyurethane adhesive (PUA) was prepared to realize a convenient encapsulation strategy for lead efficient sedimentation and for attachable perovskite solar cells (PSCs). The modified PUA can completely self-healing within 45 minutes at room temperature and it has a lead ion blocking rate of 99.3% in the dripping experiment. The PUA film can directly contact with the metal electrode surface with a slight efficiency improvement from 23.96% to 24.15%. The thermal stability of 65℃ and humidity stability of 55% RH is superior to the encapsulated devices with polyisobutylene. The PUA film has strong adhesion to flexible substrate, and the initial efficiency of flexible perovskite module (17.2%) encapsulated by PUA remains 92.6% within 1825 h. These results suggest PUA encapsulation route is universal for rigid and flexible PSCs with enhanced stability and low lead hazardous. Moreover, it was found that the flexible PSCs can be well attached to varied substrates with PUA, providing a facile route for the attachable PSCs in various scenarios without additional encapsulation and installation.

The paper presents the incorporation of in silico missenses and studies the effect of missenses to understand its effect on the Ligand-Protein interactions, of COVID-19 protein. In silico protein-ligand interaction, studies are being used to understand and investigate the drug-likeness of various molecules. 19 novel COVID-19 proteins are designed by inducing in silico missenses by mutating N691 amino acid residue in 7bv2 protein, the only residue forming H-bond with the ligand molecule in the parent protein. The work illustrates the effects of in silico-induced mutation on various interactions such as H-Bond, VDW, π-alkyl interactions, and changes in the number and type of surrounding amino acid residues. The results have suggested a common pattern of behavior on mutation with T, V, W, and Y. Further, it is observed that the number and type of amino acid residues increase on mutation, suggesting future possibilities to understand the effect of natural mutation on the binding of a ligand molecule with the protein.

Capillary Refill Time (CRT) assesses peripheral perfusion in resource-limited settings. However, the repeatability and reproducibility of CRT measurements are limited for individuals with darker skin. This paper presents quantitative CRT measurements demonstrating good performance and repeatability across all Fitzpatrick skin phototypes. The study involved 22 volunteers and utilized controlled compression at 7 kPa, an RGB video camera, and cocircular polarized white LED light. CRT was determined by calculating the time constant of an exponential regression applied to the mean pixel intensity of the green (G) channel. An adaptive algorithm identifies the optimal regression region for noise reduction, and flags inappropriate readings. The results indicate that 80% of the CRT readings fell within a 20% range of the expected CRT value. The repetition standard deviation was 17%. These findings suggest the potential for developing reliable and reproducible quantitative CRT methods for robust measurements in patient triage, monitoring, and telehealth applications.

Changes in anvil cloud area with warming are a leading source of uncertainty in estimating the Earth's climate sensitivity (Forster et al 2021). Most approaches to bounding this area feedback rely on climate models or expert assessment. Here, we use observations and theory, a "storyline approach", to bound it. We first derive a simple but quantitative expression for the anvil area feedback, which is shown to depend on the present day, measurable cloud radiative effects and the fractional change in anvil area with warming. Satellite observations suggest an anvil cloud radiative effect of about \(\pm\) 1 Wm-2, which requires the fractional change in anvil area to be about \(\mp\) 50 % K-1 to produce a feedback equal to its present-day lower bound. We use theory and observations to show that the change in anvil area is closer to about \(-\)4 % K-1. This rules out the previous estimate of the area feedback and leads to our new estimate of 0.02 \(\pm\) 0.07 Wm-2K-1 which is many times weaker and more constrained. In comparison, we show the anvil cloudy albedo feedback to be much less constrained. This poses an obstacle for bounding the Earth's climate sensitivity.

The article investigated the search for favouritism by candidates to influence the arbitration committee during oral exams since they need to pass exams to be admitted into the public sector in Turkey. The difficulties faced by candidates when finding favour, the efforts of their families, and their need for moral relief in complicated and legally criminalized acts emerged in a qualitative study. Based on an analysis of people looking for favouritism, we developed 5 groups of ways of thinking to justify their act: obedience to the system requirement, socio-economic status anxiety, approval of the merit, minimizing the risk, and career enhancement. On the one hand, candidates argue that they do it because the system requires it. On the other hand, they see it as an approval of merit. They even make their ability to find a favour a part of their success story.

Cancer is a fatal genetic disease involving unregulated cell growth and proliferation with varying underlying complexities including immune evasion, treatment resistance and recurrence, and optimized treatment is required for proper cure. Molecular studies have revealed that tumors are extremely heterogeneous in nature, leading to the complexity of cancer development, which is ultimately linked to its genetic machinery. It would require effective targeting of dysregulated molecular mechanisms involving growth factors, regulatory proteins, cell adhesion molecules, and molecules of immune system mainly driven by alterations in tumor suppressor genes and oncogenes that may vary among different cancer types. Importantly, patients with the same type of cancer respond differently to available cancer treatments, indicating the need for patient-specific treatment options. Thus, in-depth genomic studies of patients’ tumors are needed to fully understand the determinants of cancer initiation and progression for effective targeted therapy. Precision oncology has evolved as a form of cancer therapy focused on genetic profiling of tumors to identify molecular alterations involved in cancer manifestation for tailored individualized treatment of the disease. Accordingly, there have been great developments in the formulation and production of anticancer agents in recent years owing to advances in molecular technologies enabling precise targeting of oncogenic pathways involved in disease progression. This article aims to briefly explain the foundations and frontiers of precision oncology in the context of advancements in the tools and techniques associated with the process to assess its scope and importance in realizing the intended goals.

For patients with acute ischemic stroke, histological quantification of thrombus composition provides evidence for determining appropriate treatment. However, the traditional manual segmentation of stained thrombi is laborious and inconsistent. In this study, we propose a label-free method that combines optical diffraction tomography (ODT) and deep learning (DL) to automate the histological quantification process. The DL model classifies ODT image patches with 95% accuracy, and the collective prediction generates a whole-slide map of red blood cells and fibrin. The resulting whole-slide composition displays an average error of 1.1% and does not experience staining variability, facilitating faster analysis with reduced labor. The present approach will enable rapid and quantitative evaluation of blood clot composition, expediting the preclinical research and diagnosis of cardiovascular diseases.
Tics in ADHD

March 27, 2024
Originally a blog post at https://tics.wustl.edu/tics-in-adhd, 27 Feb 2019.ADHD is very common in people with tics: at least 50% of children with tics also have ADHD [1]. What about the other side? That is, how common are tics in children with ADHD? Previously I would have said, “well, more common than in kids without ADHD” [2]. That statement is true, but dramatically understates the situation.The best data we have comes from two randomized, controlled treatment studies of ADHD, because they observed the children prospectively for tics, blind to treatment assignment. Law and Schachar [3] carried out a careful, randomized controlled trial of methylphenidate for ADHD, lasting 1 year, in 91 children with tics (age 8). They monitored carefully for tics. Children who at the beginning of the study had “a severe motor or vocal tic disorder or Tourette’s disorder,” or who had been treated for tics, were not allowed to participate. Still, mild to moderate tics were observed in 30% of children at the start of the study (27 of 91). During the next year, 12 of the children without tics at the start of the study developed “clinically significant tics for the first time (i.e., moderate or worse).” This rate was essentially the same in children on or off methylphenidate—in other words, the risk factor is ADHD, not the stimulant. By the end of the study, more than 43% of children with ADHD had tics. We can say “more than” for at least three reasons. First, children with “severe” chronic tics or a history of treatment for tics were excluded from participation. Second, children who developed mild tics for the first time during the year of follow-up were not counted. Third, they diagnosed tics based on reports from parents and teachers–with careful questioning by trained research staff–but only supplemented by direct examination at the research visits if tics were reported to be “moderate,” “severe,” or “Tourette-like.” We know from our recent New Tics study and previous research that many tics not recognized by parents or teachers are identified when the child is observed by clinicians or trained research staff [4]. For all these reasons, probably even more children with ADHD had tics than the 43% reported by Law and Schchar.  Spencer and colleagues [5] reported on a large sample of boys with ADHD. 34% had a tic disorder at the start of the study, and 20% of the remaining boys developed tics at follow-up, so that by the end of the study half of the boys (64 of 128) had a current or past tic disorder. (In boys without ADHD, only 10 of 110 had a tic disorder by the end of the study.) The positive news was that tic disorders remitted faster than ADHD did. These diagnoses were based on DSM-III-R, which required impairment in a life role or marked distress to diagnose a tic disorder. Presumably rates would have been even higher if less bothersome tics were counted.A cross-sectional study performed face-to-face, semi-structured diagnostic interviews in children that teachers and parents identified as having possible ADHD or tics, and found a  chronic tic disorder in 57% of children diagnosed with ADHD [6]. A more recent report found tics to be 4-6 times more common in children with vs. without ADHD, and the children with tics tended to have more clinical problems and lower quality of life [7]. Interestingly, over 3 decades ago, Comings et al. concluded from clinical experience that about half of children seen for ADHD (only) either had motor or vocal tics or a relative with TS [8,9].

The rusty patched bumble bee, Bombus affinis, is an important pollinator in North America and a federally listed endangered species. Due to habitat loss and large declines in population size, B. affinis is facing imminent extinction unless human intervention and recovery efforts are implemented. To better understand B. affinis biology and population genetic and genomic landscapes, we sequenced and assembled the B. affinis genome from a single male. Whole genome HiFi sequencing on PacBio coupled with HiC sequencing resulted in a complete and highly contiguous contig assembly that was scaffolded into a chromosomal context, resolving 18 chromosomes for this species. All material for both HiFi and HiC sequencing was derived from a single abdominal tissue segment from the one male. These assembly results, coupled with the minimal amount of tissue destructively sampled, demonstrates methods for generating contiguous and complete genomic resources for a rare and endangered species with limited material available and highlights the importance of sample preservation. Precise methods and applications of these methods are presented for potential applications in other species with similar limitations in specimen availability and curation considerations.

Global warming has been affecting human health, including direct mortality and morbidity from extreme heat, storms, drought and indirect infectious diseases. It is not only “global” but extremely “personal” – it is a matter of life and death for many of us. In this perspective, we propose the use of wearable technologies for localized personal thermoregulation as an innovative method to reduce the impact on health and enable wider adaptability to extreme thermal environments. The start-to-art thermoregulation methods and wearable sensing technology are summarized. In addition, the feasibility of thermoregulation technology in preventive medicine for promoting health under climate change is comprehensively discussed. Further, we provided an outlook on health-oriented closed loop that can be achieved based on parallel thermoregulation and multiple data inputs from the physiological, environmental, and psychological cues, which could promote individuals and the public to better adapt to global warming.

Milk is containing immunoglobulins, lactoferrin, lysozyme, lactoperoxidase, peptidoglycan recognition protein, vitamins C and oligosaccharides which are against microbial infections. Lactoferrin is one glycoprotein detected in milk of livestock such as cow, buffalo, and camel, as camel milk containing highest amount compared to the milk from other livestock species. Activation, proliferation, and regulation of the phagocytic action of immune cells are facilitated by the lactoferrin. The antiviral actions of lactoferrin are against both DNA and RNA viruses such as hepatitis, herpes simplex viruses, HIV, rotavirus, and respiratory viruses by binding viral particles, inhibit viral adhesion, and entry into target cells. Also, lactoferrin may directly interact with viral receptors such as heparan sulfate on the cell surfaces and prevent the virus attachment and infection. The boosting host immune system by nutritional supplements such as lactoferrin may be effective against viruses' entry and infection into the host cells. Milk lactoferrin as powder or tablets may be a novel promising candidate and preventative treatment for more severe cases of viral infections. However, it needs more studies on dosage to verify its efficacy on prevention and treatment.
