Objectives: In recent years, with the incidence of bilateral cochlear implantation (CI) increasing, understanding the impact of CI on otolith function is of greater necessity. This study aims to investigate the development of gross motor and otolith function in patients with inner ear malformations (IEMs) by vestibular evoked myogenic potentials (VEMP). Materials and Methods: A total of 78 patients with sensorineural hearing loss (SNHL) (age 5.7±4.1 years) were divided into two groups based on the presence (IEM group, n=39) or absence (control group, n=39) of IEMs. VEMP was conducted before and 1–3 months after CI, and gross motor development assessed. Results: The mean ages of head control and independent walking were delayed in the IEM group compared with control group ( p=0.02). The preoperative cVEMP and oVEMP response rates were higher in the control groups (60% and 86.95%) than in the IEM group (57.69% and 74.35%) ( p<0.05). Additionally, abnormal cVEMP was associated with delayed acquisition of independent walking ( p=0.017). Saccular and utricular functions after CI were lost by 40% and 31.75%, respectively, in group of patients present preoperatively VEMPs waveform (n=25). Conclusions: Balance development is more reduced in patients with SNHL and IEMs than in patients without IEMs. The otolith-vestibular nerve conduction pathway can be affected by CI and lead to otolith function impairment. As such, evaluating the otolith and balance functions before CI is necessary and should be considered in clinical practice.

This letter presents a 1-3GHz low-power, fast-locking self-biased phase-locked loop (SPLL) for multiprotocol SerDes applications. The PLL realizes adaptive bandwidth tracking based on fast-locking current injection, which accelerates loop acquisition and maintains reduced settling time across a wide frequency range. Additionally, a start-up module is adopted to reset the system quickly to an optimal initial operating frequency. The proposed PLL, fabricated in TSMC 28-nm CMOS process and occupies a compact 0.028mm2 area. It achieves a roughly constant settling time of 5 μs over all frequencies and division ratios range. Compared with the typical SPLL, the measured settling time can be shortened about 85% large division ratios.

Background: Atopic dermatitis (AD) endotypes differ with ethnicity. We examined the skin microbiota, cytokine-, and lipid-profiles in Greenlandic Inuit and Danish children with AD. Methods: 25 Inuit children with AD and 25 Inuit control children were clinically examined and compared to previously collected data from 25 Danish children with AD. Skin tape strips and skin swabs were collected from lesional and non-lesional skin. Levels of cutaneous immune biomarkers, free sphingoid bases and their (glycosyl)ceramides were analyzed. Skin swabs were analyzed with 16S rRNA and tuf gene for characterization of bacterial species communities. Results: Bacterial β-diversity was significantly different between Inuit and Danish AD skin, in both lesional (p<0.001) and non-lesional (p<0.001) AD skin, and there was a higher relative abundance of Staphylococcus aureus in Danish compared to Inuit lesional (53% vs. 8%, p<0.01) and non-lesional skin (55% vs. 5%, p<0.001). Danish AD children had a higher α-diversity than Inuit children in non-lesional ( p<0.05) but not in lesional skin. Significantly higher levels of type 2 immunity cytokine interleukin (IL)-4 (p<0.05) and IL-5 (p<0.01) were identified in Inuit compared to Danish AD children. In contrast, IL-33 (p<0.01) was higher in Danish lesional and non-lesional AD skin. Higher levels of long-chain glucosylceramide (GlcCER)[S](d26:1) were found in lesional ( p<0.001) and non-lesional ( p<0.001) Inuit skin compared with Danish AD skin. NMF levels were similar in Inuit and Danish AD skin. Conclusion: Skin microbiota, cytokine and lipid composition differed significantly between Inuit and Danish children with AD and showed a stronger type 2 immune signature in Inuit children.

Many reef invertebrates reproduce through simultaneous broadcast spawning, with an apparent advantage of overwhelming potential predators and maximizing propagule survival. Although reef fish have been observed to consume coral gamete bundles during spawning events, there are no published records of such predation by benthic invertebrates. Here, we document several instances of the ruby brittle star, Ophioderma rubicundum, capturing and consuming egg-sperm bundles of the mountainous star coral, Orbicella faveolata, and the symmetrical brain coral, Pseudodiploria strigosa, during spawning events in the Cayman Islands in 2012 and the Florida Keys in 2022. These observations are widely separated in space and time (>600 km, 10 years), suggesting that this behavior may be ubiquitous on western Atlantic reefs. Since O. rubicundum spawns on the same or subsequent nights as these coral species, we hypothesize that this opportunistic feeding behavior takes advantage of the coral’s lipid-rich bundles to recover energy reserves expended by the brittle star during gametogenesis. The consumption of coral gametes by adult brittle stars suggests a novel trophic link between reef invertebrates, and also provides evidence that ophiuroid-coral symbioses may oscillate between commensalism and parasitism depending on the ontogeny and reproductive status of both animals. Our observations provide insights into the nuanced, dynamic associations between coral reef invertebrates and may have implications for coral fecundity and resilience.

A recent quantitative study showed volunteering to be an important protective factor against the negative psychological impact of the COVID-19 pandemic. This study aimed to further explore this area of research by analysing the experiences of those volunteering during the pandemic using qualitative methodology. Semi-structured interviews of six individuals volunteering in various roles throughout the pandemic have been analysed using Interpretative Phenomenological Analysis. There emerged three superordinate themes; Staying Connected, Doing Something Useful and Having a Choice. The results suggest that volunteering can help individuals to overcome the negative effects of social isolation and strengthen their sense of connectedness, to find meaning by engaging in interesting and useful activities, and, finally, to experience autonomy in the autonomy-frustrating lockdown context. The findings broaden understanding of the protective impact of volunteering which could be used to inform public health interventions following infectious outbreaks.

Freshwater habitats are under increasing pressure from numerous anthropogenic forces, including the introduction of alien species capable of altering ecosystems and threatening native species. Although alien species themself are likely to experience loss of genetic diversity when colonising novel environments, some manage to become invasive, suggesting that other factors might facilitate their adaptive capacity. Using a hologenomic approach, we elucidate population genomic trends, the gut microbiota composition and genome-environment-microbiota interaction in the endemic and endangered Spanish toothcarp (Aphanius iberus) and the highly invasive Eastern mosquitofish (Gambusia holbrooki). We found clear genetic signatures of captive breeding in the populations of A. iberus, while G. holbrooki are characterised by an overall low level of heterozygosity and likely signs of multiple introductions. Gut microbial communities of the two species differed significantly across locations, but no sign of increased microbial plasticity was detected in G. holbrooki. However, we report that the genetic profile of each fish was able to explain a considerable part of the microbiota variation measured across individuals. Using shotgun metagenomics, we observed an overall high functional capacity of the microbiota in both species, but we identified no significant differences in the functional capacity between them. The role of the gut microbiota in invasive species and conservation warrant further research using direct comparisons or controlled mesocosm setups, but based on the results of the current study, the gut microbiota of invasive species

This article presents a time domain multiply-and-accumulate (MAC) engine used for convolutional neural networks. Time domain is chosen for efficiency as it allows for compact representation of multi-bit inputs on a single wire. This reduces gate count and switching capacitance (Cdyn) compared to traditional all-digital implementation. The inputs are encoded by selecting a pulse of varying width depending on input code. The multiplication operation and accumulation is implemented using a digitally controlled switched-ring oscillator time-to-digital converter functioning as a time accumulator. The digital control allows for accumulation and quantization of two signals simultaneously, halving the required time to quantize a certain value. The proposed MAC is designed in a 28nm CMOS process and can achieve a simulated power efficiency of 0.32pJ/b, which is 1.8X better than what can be achieved by a single input gated ring oscillator (GRO) design.

Adeno-associated viruses (AAVs) are the vector of choice for delivering gene therapies that can cure inherited and acquired diseases. Clinical research on various AAV serotypes significantly increased in recent years alongside regulatory approvals of AAV-based therapies. The current AAV purification platform hinges on the capture step, for which several affinity resins are commercially available. These adsorbents rely on protein ligands – typically camelid antibodies – that provide high binding capacity and selectivity, but suffer from low biochemical stability and high cost, and impose harsh elution conditions (pH < 3) that can harm the transduction activity of recovered AAVs. Addressing these challenges, this study introduces peptide ligands that selectively capture AAVs and release them under mild conditions (pH 6.0). The peptide sequences were identified by screening a focused library and modeled in silico against AAV serotypes 2 and 9 (AAV2 and AAV9) to select candidate ligands that target homologous sites at the interface of the VP1-VP2 and VP2-VP3 virion proteins with mild binding strength (K D ~ 10 -5-10 -6 M). Selected peptides were conjugated to Toyopearl resin and evaluated via binding studies against AAV2 and AAV9, demonstrating the ability to target both serotypes with values of dynamic binding capacity (DBC 10% > 10 13 vp per mL of resin) and product yields (~50-80%) on par with commercial adsorbents. The peptide-based adsorbents were finally utilized to purify AAV2 from a HEK 293 cell lysate, affording high recovery (50-80%), 80-to-400-fold reduction of host cell proteins (HCPs), and high transduction activity (up to 80%) of the purified viruses.

The increasing demand for electricity and global attention has led energy planners and developers to explore and develop clean energy. In this case, Renewable Energy Source (RES) has become an alternative source of energy generation. Due to the infrequent nature of renewable energy, interrupted power availability cannot be directly used by the load system. To overcome these issues, a DC-DC converter will implement and compensate the source power, but every source needs a Multi-Port Converter (MPC) in the hybrid system. This work aims to develop a multi-port DC-DC converter for integrates multiple Renewable Energy Sources (RES) with variable input voltage and load characteristics. The proposed circuit will absorb maximum power from various renewable resources while maintaining a high output load power adjustment, transfer efficiency and reliability function using Assimilate Power Flow Control (APFC) technique control schemes. The converter topology is utilized for high-power applications with hybrid energy storage system is proposed. The new topology assimilates multiple renewable energy and power multiple loads with changed output levels. Therefore, the controller circuit automatically adjusts the duty cycle value to obtain a desired constant output voltage value, despite all the source voltage and load output changes. In order to achieve this goal, an appropriate feedback controller can adjust the output voltage and the reference value by automatically adjusting the input voltage’s fast response to changes in the duty cycle and output load and low noise sensitivity with low overshoot and zero steady-state error. The proposed multi-port DC-DC converter topology is established in MATLAB 2017b software; the performance of the proposed APFC techniques based MPC converter operation are determined by the steady-state energy flow under various load varying condition. The proposed APFC techniques’ effectiveness is evaluated for each of the different parameters like steady-state error, THD, and the system’s efficiency.

Abstract With the increasing number of transcatheter aortic valve implantations (TAVI) being performed comes a need to better understand TAVI-associated complications such as infective endocarditis (IE), leaflet thrombosis, and paravalvular regurgitation. An 83 year-old women, who had undergone TAVI followed by permanent pacemaker implantation 3 months before, presented to outpatient clinic with fever lasting for 5 days. History revealed that fever reached 39°C and was subsided by the initiation of amoxycillin/clavulinic acid prescribed by her family physician. Transesophageal echocardiography (TEE) revealed normal aortic leaflet thickness and motion. A mass at aorto-mitral continuity in left atrium was detected (Figure 1A, Video 1). The mass was heterogenous, 8×3 mm in size, and did not have visual characteristics of vegetation. Mitral valve seemed unaffected. There was no mitral regurgitation. No paravalvular abscess, pseudoaneurysm, or fistula was detected. We had confirmed that the mass was not present before the TAVI after reviewing preprocedural computed tomography (CT) scan (Figure 1B). There was fluorodeoxyglucose uptake around TAV and permanent pacemaker leads in positron emission computed tomography (Figure 1C). With the fever early after TAVI and a suspicious mass adjacent to TAV, we decided to treat the patient as “possible IE” according to modified Duke criteria. A 6-week therapy of vancomycine plus rifampin accompanied by 2-week therapy of gentamycine was initiated. The first set of blood cultures turned out to be negative. Second set of blood cultures were also negative at the second week of hospitalization. TEE was repeated at the 3rd and 5th weeks and showed identical findings to the first TEE (Figure 2, Video 2-3). Clinical condition of the patient was very good. She did not develop fever after hospitalization. The patient was discharged uneventfully after 6 weeks of antibiotic therapy. We had concluded that the mass could be thrombus in origin. After 6 motnhs of warfarin plus clopidogrel therapy control TEE revealed that the mass at aorto-mitral continuity had disappeared, mitral valve was normal, TAV was normal with similar valvular gradient and had trivial paravalvular regurgitation identical to initial examinations (Figure 2, Video 4). There was no finding of paravalvular abscess, pseudoaneurysm, or fistula. The patient was still asymptomatic with good functional capacity and TTE showed normal valvular function at 1-year followup of TAVI.

A 65 year-old with history of prior ablations for regular narrow QRS short- RP tachycardia presented with recurrence of palpitations. An electrophysiological study showed long VA tachycardia with concentric atrial activation with a left ventricular origin extrastimulus delivered during His refractoriness, advancing the next ‘A’. A HRVPB can only reset an ORT if it ‘pulls in’ the local V at the ventricular insertion of an accessory pathway. As showcased in this case, erudite analysis of the pattern of perturbation of local ventricular electrograms is of paramount significance when interpreting responses to this maneuver. This concept when fortified with a heightened index of clinical suspicion for mitral annular block, anatomical knowledge of the pattern of LA-CS muscular connections, and pathway orientation, led to accurate electrophysiological diagnosis and management.

Jupyter Notebook is a popular tool among data analysts and scientists for working with data. It provides a way to combine code, documentation, and visualizations in a single, interactive environment, facilitating code reuse. While code reuse can improve programming efficiency, it can also decrease readability, security, and overall performance. We conduct a large-scale exploratory study of code reuse practices in the Jupyter Notebook development community on the Stack Overflow platform to understand the potential negative impacts of code reuse. Our findings identified 1,097,470 Jupyter Notebook clone pairs that reuse Stack Overflow code snippets, and the average code snippet has 7.91 code quality violations. Through our research, we gain insight into the reasons behind Jupyter Notebook developers' decision to reuse code and the potential drawbacks of this practice.

Perceived stress has increased due to the COVID-19 pandemic. In addition, those with diagnosed emotional disturbances note higher perceived stress ratings than those without these conditions. Emotion-focused coping can be a practical adjunctive component with problem-based solutions during elevated stress. However, it is unknown if there are differences in perceived stress levels and emotional affect in adults with and without emotional disturbances using a novel emotion-focused coping strategy. A cross-sectional study of 97 adults using the novel strategy completed an online survey of the Perceived Stress Scale (PSS-10) and Positive and Negative Affect Schedule (PANAS). Group one (NEDG) included 34 individuals without a history of emotional disturbance. Group two (EDG) included 63 individuals reporting an emotional disturbance (Anxiety; N= 58 & Depression; N=5). There was no significant difference in perceived stress between the NEDG (17.6 + 5.3) and EDG (17.0 + 5.5) groups. Moreover, there were no significant differences in PANAS between groups. Positive affect was in the 51st percentile (95 % CI: 45.7-56.6%), and negative affect was in the 74th percentile (95% CI: 70.4-78.9%) of normative data. Individuals with or without emotional disturbance may experience similar perceived stress levels and emotional affect while using a novel coping strategy. Additional research investigating this novel strategy is warranted.

Background Magnesium sulphate is widely used in antenatal mothers for various indications such as neuroprotection, tocolysis and preeclampsia. Some studies suggest that there is alteration in intestinal motility and blood flow in preterm neonates as a result of exposure to Magnesium sulphate. Objective To evaluate the effect of antenatal magnesium Sulphate (MgSO 4) on mortality and morbidity outcomes related to the gastrointestinal system (GI) in preterm infants. Search strategy PubMed, CINAHL, Embase, and CENTRAL were searched through up to November 2022. Data collection and Analysis Two authors independently conducted data extraction. A random-effects model meta-analysis was performed. All included studies were assessed for methodological quality using appropriate quality assessment tool. The GRADE approach was used to assess the overall certainty of evidence. Main Results A total of thirty-eight observational and six RCTs involving 51,466 preterm infants were included. There were no increased odds of stage ≥2 NEC, (n= 50,727, OR:1.0; 95% CI: 0.89-1.12, I 2- 7%), SIP ( n= 34,186, OR: 1.22, 95% CI: 0.94-1.58, I 2-30% ), feed intolerance (n= 414, OR: 1.06, 95% CI: 0.64-1.76, I 2-12%) in infants exposed to antenatal MgSO 4. On the contrary, the incidence of surgical NEC was significantly lower in MgSO 4 exposure infants (n= 29,506 OR:0.74; 95% CI: 0.62-0.90, ARR: 0.47%). Studies assessing the effect on GI-related mortality were sparse to make any conceivable conclusion. GRADE certainty of findings were ‘very low’. Conclusion Antenatal MgSO 4 did not increase the incidence of gastrointestinal-related morbidities or mortality in preterm infants.

Introduction: A global health issue known as antimicrobial resistance (AMR) transcends geopolitical boundaries. Surgical antibiotic prophylaxis (SAP) is the process of administering antimicrobial to treat contagions as a preventative measure, avoid them before, during, and after surgery. During surgery or after surgery there may be chances of acquiring infection. Infection at the surgical site is one such complication known as surgical site infection (SSI). It is one of the problems that reoccur the most frequently in clinical setting. Surgical site infection is described as an infection that develops with in thirty days of surgery and might be deep, affecting the organs reached during surgery, or superficial, involving only the skin. SSIs are occasionally the leading cause of death following surgical treatments. So, to reduce these types of complication we use surgical antibiotic prophylaxis. Methods: PubMed, Google Scholar, ResearchGate, and healthcare system evidence were searched from 2005 to 2022 for systemic review that was published in the English language. Result: Data were extracted for all primary outcomes, 38 reviews were included, and review quality was evaluated using AMSTAR 2. The most often reported administration of antibiotic, timing, drug class, and primary result, respectively, were preoperative antibiotic administration, first generation cephalosporin usage, and surgical site infection (SSI). Results indicate that, in comparison to a placebo or no SAP, SAP may, on average, decrease SSIs. The finding showed that postoperative SAP did not differ significantly from intraoperative SAP in reducing SSI.

Objective: To determine the success rate of vaginal birth after caesarean (VBAC) in Indian women, identify the factors that predict its success, and assess the maternal and neonatal outcomes following a trial of labour after caesarean (TOLAC). Design: Prospective observational study Setting: Department of Obstetrics and Gynaecology, Post Graduate Institute of Medical Education and Research, Chandigarh, India Sample: 124 women with previous LSCS who opted for TOLAC Methods: A prospective observational study involving women with one previous lower segment caesarean section (LSCS) who were admitted for TOLAC between January 2019 and June 2020. Main outcome measures and Results: During the study period, 124 women with previous LSCS who opted for TOLAC were included, of whom 68 (54.8%) had successful VBAC and 56 (45.2%) had failed TOLAC. The induction of labour (IOL) rate in the study was 69.4%, and 30.6% of women had spontaneous onset of labor. VBAC rates were significantly higher in women who went into labour spontaneously (84.2% vs. 15.8%). Maternal complication rates were comparable, whereas the neonatal complication rate was significantly higher in neonates born by CS (51.7% vs. 30.8%), with a greater incidence of low birthweight (LBW) and transient tachypnea in the newborn (TTNB). Conclusions: TOLAC can be considered a safe option for women with a previous caesarean when combined with vigilant and stringent labour monitoring, despite the use of IOL agents.

A brain tumor is a dangerous cancer that develops when cells divide uncontrollably and abnormally. Recent advancements in deep learning have aided the medical imaging industry in diagnosing various disorders medically. Convolutional neural networks are the most often used machine learning algorithm for visual recognition and learning. Additionally, we demonstrate by using CNN to classify brain MRI images into two categories: cancer and non-cancer. Using the transfer learning method, we evaluated our convolutional model’s performance to previously trained ResNet-v2-152, Inception-v3, and Inception-Resnet-v2 models. As a result of the experiment, a moderate dataset was used. However, the test result indicates that the suggested model’s accuracy was adequate, reaching 99 percent, compared to 98 percent for ResNet-v2-152, 98 percent for Inception-v3, and 97 percent for Inception-Resnet-v2. The suggested model requires far less computational resources and is more efficient.

Objective Little has been published about maternity outcomes from New Zealand’s unique handling of the COVID-19 pandemic. Objectives were to determine obstetric outcomes between the variants, identify risk factors, and whether the changes to healthcare delivery affected pregnancy outcomes. Design This was a case control study comparing singleton pregnancies affected by the Delta and Omicron strains of COVID-19. The COVID 19-free controls were from 2019. Setting & Population The largest tertiary maternity unit in New Zealand providing taxpayer funded healthcare to a multi-ethnic, high deprivation index population with complex health needs. Methods Data were extracted from electronic record systems and further verified by reviewing patient’s notes. The risk of an event was modelled with logistic regression. The multivariate analyses adjusted for known clinical risk factors and other significant differences between the groups. Main Outcome Measures Outcomes of interest included admission for COVID-19, adverse pregnancy outcomes, including placentally-mediated ones. Results In the study population of > 8,000 pregnancies, Delta variant was associated with significantly worse maternal and obstetric outcomes. Fetal anomalies and most placentally-mediated adverse outcomes of pregnancy in the COVID-19 affected cohort did not persist once adjusted for underlying maternal risk factors, except for a 4-fold increased risk of stillbirth. Vaccination was protective against admissions and severe disease (OR 0.19;95%CI 0.11-0.32). Conclusions While the Delta variant has been associated with poorer outcomes, modifications to the delivery of maternity care during the pandemic could have unintended consequences on how patients utilised healthcare; this may have contributed to poorer outcomes.

Biotechnology is the science of applied biological process that blends natural science and engineering to comprehend and control biology at the molecular level for a profound impact. It accomplishes gene recombination, cloning of living things, and splicing of genes from the DNA of one organism into the genome of unrelated species. It plays a significant role in bio-agriculture, genomics, biochips, medicines, robotic military, bioinformatics, the biotech industry, stem cell research, fingerprinting, and bio-manufacturing which is essential for improving national security. Modern biotechnology is a multidisciplinary field and has proven a miracle for militaries from both; an offensive and defensive standpoint. Biotechnology has both prospects and constraints. Bio-weapons lead to disasters more dangerous than nuclear accidents. The database freely available on the internet has the potential for the development of a wide range of novel pathogens that can attack the plant, animal, and human populations worldwide. Biotechnology has created amazing possibilities and brought radical changes for the military in bio-armory, bio-sensors, biocomputing, bioengineered materials, biofuels, and biomimetics. This article highlights aspects of biotechnology as an evolving dimension of security, legal defense mechanisms, collaboration, and adherence of different concerned authorities, and analyzes ways to counter different threats of a bioweapon and boost national security. Nevertheless, it is clear biotechnology will be as important to consumer economics in the next century as physics and chemistry were in the last century.
