Abstract
BACKGROUND AND PURPOSE Identification of new MS lesions on longitudinal MR imaging by human readers is time-consuming and prone to error. Our objective was to evaluate the improvement in the performance of subject-level detection by readers when assisted by the automated statistical detection of change algorithm. MATERIALS AND METHODS A total of 200 patients with MS with a mean interscan interval of 13.2 (SD, 2.4) months were included. Statistical detection of change was applied to the baseline and follow-up FLAIR images to detect potential new lesions for confirmation by readers (Reader + statistical detection of change method). This method was compared with readers operating in the clinical workflow (Reader method) for a subject-level detection of new lesions. RESULTS Reader + statistical detection of change found 30 subjects (15.0%) with at least 1 new lesion, while Reader detected 16 subjects (8.0%). As a subject-level screening tool, statistical detection of change achieved a perfect sensitivity of 1.00 (95% CI, 0.88-1.00) and a moderate specificity of 0.67 (95% CI, 0.59-0.74). The agreement on a subject level was 0.91 (95% CI, 0.87-0.95) between Reader + statistical detection of change and Reader, and 0.72 (95% CI, 0.66-0.78) between Reader + statistical detection of change and statistical detection of change. CONCLUSIONS The statistical detection of change algorithm can serve as a time-saving screening tool to assist human readers in verifying 3D FLAIR images of patients with MS with suspected new lesions. Our promising results warrant further evaluation of statistical detection of change in prospective multireader clinical studies.

Abstract
We report here the first observation of directed flow (v_{1}) of the hypernuclei _{Λ}^{3}H and _{Λ}^{4}H in mid-central Au+Au collisions at sqrt[s_{NN}]=3 GeV at RHIC. These data are taken as part of the beam energy scan program carried out by the STAR experiment. From 165×10^{6} events in 5%-40% centrality, about 8400 _{Λ}^{3}H and 5200 _{Λ}^{4}H candidates are reconstructed through two- and three-body decay channels. We observe that these hypernuclei exhibit significant directed flow. Comparing to that of light nuclei, it is found that the midrapidity v_{1} slopes of _{Λ}^{3}H and _{Λ}^{4}H follow baryon number scaling, implying that the coalescence is the dominant mechanism for these hypernuclei production in the 3 GeV Au+Au collisions.

Abstract
We report the triton (t) production in midrapidity (|y|<0.5) Au+Au collisions at sqrt[s_{NN}]=7.7-200 GeV measured by the STAR experiment from the first phase of the beam energy scan at the Relativistic Heavy Ion Collider. The nuclear compound yield ratio (N_{t}×N_{p}/N_{d}^{2}), which is predicted to be sensitive to the fluctuation of local neutron density, is observed to decrease monotonically with increasing charged-particle multiplicity (dN_{ch}/dη) and follows a scaling behavior. The dN_{ch}/dη dependence of the yield ratio is compared to calculations from coalescence and thermal models. Enhancements in the yield ratios relative to the coalescence baseline are observed in the 0%-10% most central collisions at 19.6 and 27 GeV, with a significance of 2.3σ and 3.4σ, respectively, giving a combined significance of 4.1σ. The enhancements are not observed in peripheral collisions or model calculations without critical fluctuation, and decreases with a smaller p_{T} acceptance. The physics implications of these results on the QCD phase structure and the production mechanism of light nuclei in heavy-ion collisions are discussed.

Multi-omics analyses identify PREPL as a key regulator of protein trafficking, a pathway underlying Alzheimer's disease pathogenesis. Mol Pharmacol 2023:molpharm.122.000641.

Abstract
Current treatments for Alzheimer's disease (AD) help reduce symptoms for a limited time but do not treat the underlying pathology. To identify potential therapeutic targets for AD, an integrative network analysis was previously carried out using 364 human postmortem control, mild cognitive impairment and AD brains. This analysis identified proline endopeptidase-like protein (PREPL), an understudied protein, as a down-regulated protein in late-onset AD patients. In this study we investigate the role of PREPL. Analyses of data from human postmortem samples and PREPL knockdown (KD) cells suggest that PREPL expression modulates pathways associated with protein trafficking, synaptic activities, and lipid metabolism. Furthermore, PREPL KD impairs cell proliferation, modulates the structure of vesicles and levels of neuropeptide processing enzymes as well as secretion of neuropeptides. In addition, decrease in PREPL levels leads to changes in the levels of a number of synaptic proteins as well as changes in the levels of secreted Amyloid Beta (Ab) 42 peptide and Tau phosphorylation. Finally, we report that local decrease in PREPL levels in mouse hippocampus attenuates long-term potentiation suggesting a role in synaptic plasticity. Together, our results indicate that PREPL affects neuronal function by modulating protein trafficking and synaptic function, an important mechanism of AD pathogenesis. Significance Statement Integrative network analysis reveals PREPL to be downregulated in human sporadic late-onset Alzheimer's disease brains. Down regulation of PREPL leads to increases in Aβ secretion, Tau phosphorylation and decreases in protein trafficking and in long-term potentiation.

Abstract
BACKGROUND Detection of SARS-CoV-2 antibodies is essential in establishing the parameters of an individual's immune response to COVID-19, from both natural infection and vaccination. Despite this, there is currently limited clinical guidance or recommendations for serological methods for their measurement. Here, we evaluate and compare four Luminex-based assays for the multiplex detection of IgG SARS-CoV-2 antibodies. METHODS The four assays tested were Magnetic Luminex Assay, MULTICOV-AB Assay, Luminex xMAP SARS-CoV-2 Multi-Antigen IgG Assay and LABScreen COVID Plus Assay. Each assay's ability to detect antibodies to SARS-CoV-2 Spike (S), Nucleocapsid (N) and Spike-Receptor Binding Domain (RBD) was evaluated using 50 test samples (25 positive, 25 negative), previously tested by a widely used ELISA technique. RESULTS The MULTICOV-AB Assay had the highest clinical performance detecting antibodies to S trimer and RBD in 100% (n = 25) of known positive samples. Both the Magnetic Luminex Assay and LABScreen COVID Plus Assay showed significant diagnostic accuracy with sensitivities of 90% and 88% respectively. The Luminex xMAP SARS-CoV-2 Multi-Antigen IgG Assay demonstrated limited detection of antibodies to the S antigen resulting in a sensitivity of 68%. CONCLUSION Luminex-based assays provide a suitable serological method for multiplex detection of SARS-CoV-2 specific antibodies, with each assay able to detect antibodies to a minimum of 3 different SARS-CoV-2 antigens. Assay comparison identified there is moderate performance variability between manufacturers and further inter-assay variation of antibodies detected to different SARS-CoV-2 antigens.

Abstract
Fractional quantum Hall states (FQHSs) at even-denominator Landau level filling factors (ν) are of prime interest as they are predicted to host exotic, topological states of matter. We report here the observation of a FQHS at ν=1/2 in a two-dimensional electron system of exceptionally high quality, confined to a wide AlAs quantum well, where the electrons can occupy multiple conduction-band valleys with an anisotropic effective mass. The anisotropy and multivalley degree of freedom offer an unprecedented tunability of the ν=1/2 FQHS as we can control both the valley occupancy via the application of in-plane strain, and the ratio between the strengths of the short- and long-range Coulomb interaction by tilting the sample in the magnetic field to change the electron charge distribution. Thanks to this tunability, we observe phase transitions from a compressible Fermi liquid to an incompressible FQHS and then to an insulating phase as a function of tilt angle. We find that this evolution and the energy gap of the ν=1/2 FQHS depend strongly on valley occupancy.

Abstract
We report on measurements of sequential ϒ suppression in Au+Au collisions at sqrt[s_{NN}]=200 GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC) through both the dielectron and dimuon decay channels. In the 0%-60% centrality class, the nuclear modification factors (R_{AA}), which quantify the level of yield suppression in heavy-ion collisions compared to p+p collisions, for ϒ(1S) and ϒ(2S) are 0.40±0.03(stat)±0.03(sys)±0.09(norm) and 0.26±0.08(stat)±0.02(sys)±0.06(norm), respectively, while the upper limit of the ϒ(3S) R_{AA} is 0.17 at a 95% confidence level. This provides experimental evidence that the ϒ(3S) is significantly more suppressed than the ϒ(1S) at RHIC. The level of suppression for ϒ(1S) is comparable to that observed at the much higher collision energy at the Large Hadron Collider. These results point to the creation of a medium at RHIC whose temperature is sufficiently high to strongly suppress excited ϒ states.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) in the recent times have instilled signs of immunosuppression globally which has further precipitated increasing range of opportunistic infections. Mucormycosis is a distressing opportunistic fungal infection with a high incidence and is the third commonest acute invasive infection following candidiasis and aspergillosis. The aim of the present observational study is to delineate the enigmatic histopathological profile between mucormycosis cases seen prior to pandemic (PPM) and pandemic associated mucormycosis (PAM). MATERIAL AND METHODS Tissue archives of 105 histopathologically diagnosed cases of mucormycosis were included and analysed for demographical details and histopathological parameters like fungal load and localization, granuloma formation, necrosis, inflammatory infiltrate and tissue invasion. RESULTS 0ut of 105 included cases, 11/105 (10.48%) were reported PPM and 94/105 (89.52%) PAM. Among 94 cases of PAM, 51/94 (54%) cases also showed COVID-19 positivity, while 43/94 (46%) did not. Of all the histological variables, increased fungal load and necrosis were observed in PAM relative to PPM cases. CONCLUSIONS The histopathological variables like fungal load, necrosis, granuloma formation and tissue invasion, could help the clinician in assessing the clinical status at the time of tissue diagnosis and improve the treatment accordingly.

ANNALES PHARMACEUTIQUES FRANÇAISES 2023; 81:315-333. [PMID: 36037930 DOI: 10.1016/j.pharma.2022.08.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 07/01/2022] [Accepted: 08/23/2022] [Indexed: 10/15/2022]
Abstract
Oral delivery of paliperidone palmitate (PPD), a potent antipsychotic agent, has been reported with a potential risk of very serious drug-induced adverse events such as tachycardia, hyperprolactinemia, sexual dysfunction, and neutropenia. Alternatively, the potential of nasal delivery has also been explored to treat CNS complications by delivering the medicines directly to the brain bypassing the blood-brain barrier. Hence, the objectives of current work were to formulate, design, optimize, and investigate the therapeutic potency of PPD-loaded intranasal in-situ gel (PPGISG) in the treatment of schizophrenia. PPD-nanoemulsion (PNE) was fabricated using water titration technique, was further optimized via Box-Behnken design. Furthermore, the optimized PNE was evaluated for parameters such as globule size, polydispersity index, zeta potential, and % entrapment efficiency were found to be 21.44±1.58nm, 0.268±0.02, -25.56±1.6mV, and 99.89±0.25%, respectively. PNE was further converted to PPGISG utilizing two polymers, poloxamer, and guar gum. Simultaneously, ex-vivo permeation for PNE, PPGISG, and PPD-suspension was found to be 211.40±4.8, 297.89±3.9 and 98.66±1.6μg/cm2, respectively. While PPGISG nanoparticles showed 1.58 and 5.65-folds more Jss than PNE and PPD-suspension. Behavioral studies confirmed that no extrapyramidal symptoms were observed in experimental animals post intranasal administration. Finally, the outcomes of the in-vivo hemato-compatibility study proved that intranasal formulation did not cause any alteration in leukocytes, RBCs, and neutrophils count. Therefore, intranasal delivery of PPGISG can be considered a novel tool for the safe delivery of PPD in schizophrenic patients.

Beam Energy Dependence of Fifth- and Sixth-Order Net-Proton Number Fluctuations in Au+Au Collisions at RHIC. PHYSICAL REVIEW LETTERS 2023; 130:082301. [PMID: 36898098 DOI: 10.1103/physrevlett.130.082301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 11/21/2022] [Accepted: 01/11/2023] [Indexed: 06/18/2023]
Abstract
We report the beam energy and collision centrality dependence of fifth and sixth order cumulants (C_{5}, C_{6}) and factorial cumulants (κ_{5}, κ_{6}) of net-proton and proton number distributions, from center-of-mass energy (sqrt[s_{NN}]) 3 GeV to 200 GeV Au+Au collisions at RHIC. Cumulant ratios of net-proton (taken as proxy for net-baryon) distributions generally follow the hierarchy expected from QCD thermodynamics, except for the case of collisions at 3 GeV. The measured values of C_{6}/C_{2} for 0%-40% centrality collisions show progressively negative trend with decreasing energy, while it is positive for the lowest energy studied. These observed negative signs are consistent with QCD calculations (for baryon chemical potential, μ_{B}≤110 MeV) which contains the crossover transition range. In addition, for energies above 7.7 GeV, the measured proton κ_{n}, within uncertainties, does not support the two-component (Poisson+binomial) shape of proton number distributions that would be expected from a first-order phase transition. Taken in combination, the hyperorder proton number fluctuations suggest that the structure of QCD matter at high baryon density, μ_{B}∼750 MeV at sqrt[s_{NN}]=3 GeV is starkly different from those at vanishing μ_{B}∼24 MeV at sqrt[s_{NN}]=200 GeV and higher collision energies.

Abstract
Minimally invasive interventional techniques are being utilised more frequently in the management of acute and chronic pulmonary emboli; however, robust clinical evidence is only emerging for the utilisation of these techniques. Hence, there is a need for a robust mechanism of patient selection and careful consideration of the benefits and risks of the interventions. In this review, we discuss the risk stratification mechanisms; the role of the multidisciplinary pulmonary embolism response team to support decision-making; and describe the various commonly used interventional techniques and how these can be integrated into treatment strategies for the benefit of our patients.

Abstract
Abstract
Introduction
The Norman Power Centre (NPC) is an Intermediate Care Unit, in Birmingham, UK, providing enhanced assessment beds (EAB) where patients undergo functional assessment after an acute admission. There is little published data regarding the outcomes for patients admitted to EAB, so we set out to analyse outcomes in our unit.
Method
Data was collected from 50 patients who were discharged from EAB between September 2021 and March 2022.
Results
The mean length of stay was 36 days, median was 29 days. Of the 50 patients: 4 went home with no services, 9 went home with Early Intervention Community Team (EICT) support, 5 went home with package of care (not EICT), 13 went to new residential home placements, 6 went to new nursing home placements, 11 were re-admitted to hospital, 1 died and 1 received palliative care. 28 patients went to the destination that was originally intended on admission, 9 went to a less restrictive option and 12 required a higher dependency destination (predominantly re-admission to hospital.) The change in Elderly Mobility Scale from admission to discharge ranged from -1 to +15. Mode and median were both 0 and mean change was +2. 49 patients had Barthel scores on admission and discharge. Change in score ranged between -1 and +9. Mode and median change was 0, and mean was +1.7.
Conclusions
This data shows positive outcomes in terms of discharging most patients to their intended, or better, destinations. It also gives us an objective measure of the change in functional status that patients are achieving during their stay. There is a high rate of hospital re-admissions, indicating the unstable nature of the health of frail people. We are now ready to move onto a PDSA cycle to see if we can improve outcomes for our patients.

Abstract
Abstract
Introduction
The Norman Power Centre (NPC) is a 32 bedded Intermediate Care Unit, run by an acute hospital trust in Birmingham, UK, for patients who require ongoing 24-hour care, rehabilitation or further assessment, but do not need to be in an acute hospital setting. These frail patients attend numerous outpatient hospital appointments, but rarely do staff receive communication back from these outpatient reviews. This can lead to delays in implementing specialist management plans, with potential for adverse outcomes for patients and increased staff workload in seeking out the required information. A ‘Consultation Communication’ proforma was designed, to be filled in at the appointment and brought back to NPC with the patient.
Method
Patients and escorts took proformas to outpatient appointments between March and June 2022. The information on the forms was then analysed to assess completeness and usefulness.
Results
Appointments were in surgical and medical specialities, as well as imaging in three hospitals within one trust. Proformas were taken to 19/20 appointments. 100% of these were at least partially completed, with only two forms being largely incomplete. 17/19 provided information about the assessment carried out. 12/19 included recommendations relevant to admission at NPC. 13/19 had information on medication changes. 14/19 stated whether follow up was required. Eight out of nine required follow-ups had specific details included. 13/19 had the professional’s details, 11 with contact numbers. Of those without details, two were imaging appointments where contact details were not relevant.
Conclusions
This easy to implement, simple intervention, with an excellent engagement rate from both NPC and outpatient appointment staff, has led to improved continuity of care for patients. The proforma has scope to be improved based on staff feedback, and its use could be expanded across other off-site facilities such as community hospitals or care homes.

Abstract
BACKGROUND Neonates admitted to the neonatal intensive care unit (NICU) are at risk for healthcare-associated infections, including central line-associated bloodstream infections. We aimed to characterize the epidemiology of bloodstream infections among neonates with central venous catheters admitted to three Indian NICUs. METHODS We conducted a prospective cohort study in three tertiary NICUs, from May 1, 2017 until July 31, 2019. All neonates admitted to the NICU were enrolled and followed until discharge, transfer, or death. Cases were defined as positive blood cultures in neonates with a central venous catheter in place for greater than 2 days or within 2 days of catheter removal. RESULTS During the study period, 140 bloodstream infections were identified in 131 neonates with a central venous catheter. The bloodstream infection rate was 11.9 per 1000 central line-days. Gram-negative organisms predominated, with 38.6% of cases caused by Klebsiella spp. and 14.9% by Acinetobacter spp. Antimicrobial resistance was prevalent among Gram-negative isolates, with 86.9% resistant to third- or fourth-generation cephalosporins, 63.1% to aminoglycosides, 61.9% to fluoroquinolones, and 42.0% to carbapenems. Mortality and length of stay were greater in neonates with bloodstream infection than in neonates without bloodstream infection (unadjusted analysis, p < 0.001). CONCLUSIONS We report a high bloodstream infection rate among neonates with central venous catheters admitted to three tertiary care NICUs in India. Action to improve infection prevention and control practices in the NICU is needed to reduce the morbidity and mortality associated with BSI in this high-risk population.

Abstract
Stochastic resonance (SR) is a phenomenon in which an intermediate level of noise enhances the response of a weak input signal. This phenomenon is experimentally used for rehabilitation and treatment of visuomotor disorders associated with low amplitude and higher latency P100 VEPs. We presupposed that shortly it will be possible to develop and design new devices that enable multisensory SR in the audio-visual modality for human sensorimotor enhancement and rehabilitation purposes. This study was newer in which the auditory noise was used in the form of song of different tempos and their amplitude and latency of P100 PRVEP (pattern reversal visual evoked potential) was compared. Whether the different tempos song may affects the PRVEP. This study was conducted on 57 healthy volunteers in AIIMS Bhopal. The subjects were placed in front of a computer displaying a checkerboard 8x8 size. Electrodes were pasted on their scalp. The average latencies and amplitudes of the PRVEP were recorded at resting, then with the stimulus of acoustic noise in the form of low and high tempo song. The PRVEP were recorded for each event. We found that low- and high-tempo songs do not affect the latency component of PRVEP, while it significantly affects amplitude. Music therapy can help with vision rehabilitation, especially in patients with low amplitude PRVEP. A more significant number of samples for further study in this field in multisensory SR with visual evoked potentials (VEP) are necessary. We can also conclude that a sound-free environment is essential during VEP recording.

Abstract
Hydrocephalus is one of the earliest manifestations of mucopolysaccharidosis I-Hurler syndrome, and delayed treatment of hydrocephalus can lead to neurocognitive delay or even death. Optic nerve sheath diameter has been established as a noninvasive measurement to detect elevated intracranial pressure. This study aimed to establish correlations between optic nerve sheath diameter and opening pressure. Forty-nine MR images and opening pressures in patients with mucopolysaccharidosis I-Hurler syndrome were retrospectively reviewed from 2008 to 2020. The optic nerve sheath diameter was measured 3 mm posterior to the posterior margin of the globe (retrobulbar) and 10 mm anterior to the optic foramen (midpoint segment), and the average was taken between the 2 eyes. Opening pressure was measured with the patient in the lateral decubitus position with controlled end-tidal CO2 on the same day as the MR imaging. The average retrobulbar optic nerve sheath diameter was 5.33 mm, higher than the previously reported measurement in healthy controls, in patients with idiopathic intracranial hypertension, and there was a positive correlation between age and the optic nerve sheath diameter measured at the retrobulbar or midpoint segment (retrobulbar segment, R 2 = 0.27, P < .01; midpoint segment, R 2 = 0.20, P < .01). However, there was no correlation between retrobulbar or midpoint segment optic nerve sheath diameter and opening pressure (retrobulbar segment, R 2 = 0.02, P = .17; midpoint segment, R 2 = 0.03, P < .12). This study shows a higher average optic nerve sheath diameter in patients with mucopolysaccharidosis I-Hurler syndrome than in healthy controls regardless of the location of the measurement. However, the degree of optic nerve sheath dilation does not correlate with opening pressure, suggesting that increased optic nerve sheath diameter is an ocular manifestation of mucopolysaccharidosis I-Hurler syndrome itself rather than a marker of elevated intracranial pressure.

Abstract
Elliptic flow measurements from two-, four-, and six-particle correlations are used to investigate flow fluctuations in collisions of U+U at sqrt[s_{NN}]=193 GeV, Cu+Au at sqrt[s_{NN}]=200 GeV and Au+Au spanning the range sqrt[s_{NN}]=11.5-200 GeV. The measurements show a strong dependence of the flow fluctuations on collision centrality, a modest dependence on system size, and very little if any, dependence on particle species and beam energy. The results, when compared to similar LHC measurements, viscous hydrodynamic calculations, and trento model eccentricities, indicate that initial-state-driven fluctuations predominate the flow fluctuations generated in the collisions studied.

Abstract
The erector spinae plane block is a versatile regional anaesthesia technique used for a variety of truncal surgeries. A novel variation is the sacral erector spinae plane block which is gaining popularity for perineal and anorectal procedures. Local anaesthetic injected at this level blocks the sacral dermatomes and has the potential for more proximal spread to involve lumbar nerve fibres via spread to the lumbar plexus or the epidural space. The advantage of a sacral erector spinae plane block over a neuraxial block is that it is less invasive and may have a better safety profile: there is a reduced risk of epidural haematoma, epidural abscess, haemodynamic instability and motor weakness of the lower extremities. Until now, this approach has been used for midline surgical procedures when the local anaesthetic was injected bilaterally. Its application for lower limb procedures with a single unilateral injection has not been described. We report the use of a unilateral sacral erector spinae plane block at the level of the S2 median crest in two children undergoing lower limb procedures of the hip and thigh. The block was found to provide effective peri-operative analgesia with minimal need for any opioid analgesics and without any significant adverse effects.

Abstract
Migraine is a type of primary headache with a high degree of associated disability that can present with a variety of indications and co-morbidities. The role of physical therapy treatment in migraine management is largely obscure. To investigate the combine effect of aerobic exercises and therapeutic pain neuroscience education on disability, pain pressure threshold, head posture and quality of life (QoL) in patients having migraine. Subjects were screened by using Migraine Disability Assessment (MIDAS) and after screening total sample of 50 subjects were randomly assigned into two groups: Group A (Experimental, n=25) and Group B (Control, n=25). Migraine disability assessment, pressure algometer, craniovertebral angle (CVA) and migraine specific quality of life were examined before and after 6 weeks of the intervention. Group A were given aerobic exercises and therapeutic pain neuroscience education along with conventional treatment for 45 min 3 days/week for 6 weeks, whereas participants in the Group B performed conventional exercises alone for 20 min 3 days/week for 6 weeks. Significant differences were observed in migraine disability score (P=0.003) and pain pressure threshold (P=0.039, P=0.030 and P=0.025) and improvement in forward head posture (P=0.001) between the groups after the intervention period, signifying greater improvement in the group A. QoL also improved in both the groups after intervention. Main findings of the present study suggest that the therapeutic pain neuroscience education and aerobic exercises combined with conventional treatment together maybe helpful to give better quality of life, reduced disability, increased pain pressure threshold and increased CVA to patients with migraine.
