Medial Temporal Lobe Damage Impairs Temporal Integration in Episodic Memory

Published: July 2024

Abstract
Although the role of the medial temporal lobe (MTL) and the hippocampus in episodic memory is well established, there is emerging evidence that these regions play a broader role in cognition, specifically in temporal processing. However, despite strong evidence that the hippocampus plays a critical role in sequential processing, the involvement of the MTL in timing per se is poorly understood. In the present study, we investigated whether patients with MTL damage exhibit differential performance on a temporal distance memory task. Critically, we manipulated context shifts, or boundaries, which have been shown to interfere with associative binding, leading to increases in subjective temporal distance. We predicted that patients with MTL damage would show impaired binding across boundaries and thus fail to show temporal expansion. Consistent with this hypothesis, unilateral patients failed to show a temporal expansion effect, and bilateral patients actually exhibited the reverse effect, suggesting a critical role for the MTL in binding temporal information across boundaries. Furthermore, patients were impaired overall on both the temporal distance memory task and recognition memory, but not on an independent, short-timescale temporal perception task. Interestingly, temporal distance performance could be independently predicted by performance on recognition memory and the short temporal perception task. Together, these data suggest that distinct mnemonic and temporal processes may influence long interval temporal memory and that damage to the MTL may impair the ability to integrate episodic and temporal information in memory.

Abstract
The N1/P2 amplitude reduction for self-generated tones in comparison to external tones in EEG, which has recently also been described for action observation, is an example of the so-called sensory attenuation. Whether this effect is dependent on motor-based or general predictive mechanisms is unclear. Using a paradigm, in which actions (button presses) elicited tones in only half the trials, this study examined how the processing of the tones is modulated by the prediction error in each trial in a self-performed action compared with action observation. In addition, we considered the effect of temporal predictability by adding a third condition, in which visual cues were followed by external tones in half the trials. The attenuation result patterns differed for N1 and P2 amplitudes, but neither showed an attenuation effect beyond temporal predictability. Interestingly, we found that both N1 and P2 amplitudes reflected prediction errors derived from a reinforcement learning model, in that larger errors coincided with larger amplitudes. This effect was stronger for tones following button presses compared with cued external tones, but only for self-performed and not for observed actions. Taken together, our results suggest that attenuation effects are partially driven by general predictive mechanisms irrespective of self-performed actions. However, the stronger prediction-error effects for self-generated tones suggest that distinct motor-related factors beyond temporal predictability, potentially linked to reinforcement learning, play a role in the underlying mechanisms. Further research is needed to validate these initial findings as the calculation of the prediction errors was limited by the design of the experiment.

Abstract
The impact of hydroxyurea (HU) on the ovarian reserve of female patients with sickle cell disease (SCD) remains poorly elucidated. Only direct histological analysis of ovarian follicle density can effectively evaluate HU’s effect on ovarian reserve. By analyzing digitized slides of ovarian tissue from girls and young women with SCD who underwent ovarian tissue cryopreservation (OTC) before hematological stem cell transplantation, we meticulously counted follicles and categorized them based on their growth stage. We then calculated the densities of different follicle types and assessed their correlation with patient characteristics, clinical manifestations, and treatments extracted from medical records. Seventy-six patients with SCD participated in the study, with a median age at OTC of 10.2 years (interquartile range [IQR], 7.5-14.6), and 50 (65.8%) were prepubertal. Of these, 35 patients (46.1%) had received HU, with a median daily dosage of 23.0 mg/kg (IQR, 20.0-25.0) and median exposure time of 44 months (IQR, 24.0-54.0). Primordial follicle density was comparable between the HU and non-HU groups (5.8 follicles per mm2 [IQR, 1.0-13.3] vs 4.2 follicles per mm2 [IQR, 1.1-14.4], respectively; P = .95). However, in the HU group, after adjusting for age, the density of growing follicles was marginally lower than that in the non-HU group (P = .09). Notably, other parameters such as vaso-occlusive crisis did not affect follicular density. In conclusion, exposure to HU did not demonstrate a reduction in ovarian reserve in girls or women with SCD. Therefore, fertility preservation measures before initiating HU treatment do not seem necessary.

Abstract
Twice-weekly carfilzomib (27 mg/m2) plus lenalidomide and dexamethasone (KRd27) is a standard of care in relapsed/refractory multiple myeloma (RRMM). Once-weekly carfilzomib regimens have shown clinical benefits with improved patient convenience. This open-label, phase 3, multicenter, randomized study aimed to demonstrate noninferiority of the overall response rate (ORR) for once-weekly carfilzomib (56 mg/m2) plus Rd (KRd56) vs twice-weekly KRd27 in RRMM. A total of 454 patients were randomized (1:1) to receive carfilzomib as once-weekly 30-minute infusions of 56 mg/m2 (KRd56; n = 228) or twice-weekly 10-minute infusions of 27 mg/m2 (KRd27; n = 226). Baseline characteristics were balanced between groups. ORR was 82.5% (95% confidence interval [CI], 76.9-87.2) in the once-weekly group vs 86.3% (95% CI, 81.1-90.5) in the twice-weekly group (risk ratio, 0.954 [95% CI, 0.882-1.032]) and did not meet the threshold for statistical significance of noninferiority (P = .0666). Complete response (CR) or better was obtained in 46.9% of patients in the once-weekly arm and 36.3% in the twice-weekly arm. The proportions of patients who achieved CR and were also assessed negative for minimal residual disease were 21.5% and 18.1%, respectively (odds ratio, 1.235 [95% CI, 0.775-1.970]). Progression-free survival was comparable between groups (hazard ratio, 0.945 [95% CI, 0.617-1.447]). The safety profile was similar for both groups. In conclusion, although statistical significance for noninferiority of ORR was not achieved, the efficacy and safety of once-weekly KRd56 were similar to those of twice-weekly KRd27, and once-weekly KRd56 may be an effective and convenient treatment option for patients with RRMM. This trial was registered at www.ClinicalTrials.gov as #NCT03859427.

BackgroundComorbidities significantly affect bronchiectasis prognosis. Depression and anxiety are frequently encountered psychological comorbidities that have the greatest impact on bronchiectasis. This systematic review aimed to identify the prevalence of depression and anxiety and describe their implications for bronchiectasis.MethodsThree databases were searched from their inception to October 2023 for studies reporting the prevalence and/or clinical implications of depression and anxiety in patients with bronchiectasis. Two independent reviewers rated the quality of the evidence presented in the studies using the risk of bias tool for prevalence studies.ResultsOf the 50 studies identified, 17 studies with 2637 patients were included. The overall risk of bias was classified as low (10 studies) or moderate (seven studies). The pooled prevalence of depression and anxiety was 31% (95% CI 24–38%) and 34% (95% CI 28–40%), respectively. Depression was significantly higher in female compared to male patients (risk difference 10%, 95% CI 0–21%) and associated with bronchiectasis exacerbation (adjusted odds ratio 1.72, 95% CI 1.28–2.15). Depression and anxiety are closely associated with poor health-related quality of life. However, clinical outcomes including dyspnoea symptoms, severity index, computed tomography score, lung function and physical activity were not associated with depression or anxiety.ConclusionThis study revealed a high prevalence of depression and anxiety among patients with bronchiectasis. Depression was more prevalent in females and is significantly associated with bronchiectasis exacerbation. Depression and anxiety were associated with poor health-related quality of life.

AbstractA crucial determining factor in agricultural productivity is biotic stress. In addition, supply of quality food to the ever-increasing world’s population has raised the food demand tremendously. Therefore, enhanced agricultural crop productivity is the only option to mitigate these concerns. It ultimately demanded the often and indiscriminate use of synthetic agrochemicals such as chemical fertilizers, pesticides, insecticides, herbicides, etc. for the management of various biotic stresses including a variety of plant pathogens. However, the food chain and biosphere are severely impacted due to the use of such harmful agrochemicals and their byproducts. Hence, it is need of hour to search for novel, effective and ecofriendly approaches for the management of biotic stresses in crop plants. Particularly, in plant disease management, efforts are being made to take advantage of newly emerged science i.e. nanotechnology for the creation of inorganic nanoparticles (NPs) such as metallic, oxide, sulphide, etc. through different routes and their application in plant disease management. Among these, green nanomaterials which are synthesized using environmentally friendly methods and materials reported to possess unique properties (such as high surface area, adjustable size and shape, and specific functionalities) making them ideal candidates for targeted disease control. Nanotechnology can stop crop losses by managing specific diseases from soil, plants, and hydroponic systems. This review mainly focuses on the application of biologically produced green NPs in the treatment of plant diseases caused due to bacteria, viruses, and fungi. The utilization of green synthesis of NPs in the creation of intelligent targeted pesticide and biomolecule control delivery systems, for disease management is considered environmentally friendly due to its pursuit of less hazardous, sustainable, and environmentally friendly methods.

AbstractThe growing number of portable consumer-grade electroencephalography (EEG) wearables offers potential to track brain activity and neurological disease in real-world environments. However, accompanying open software tools to standardize custom recordings and help guide independent operation by users is lacking. To address this gap, we developed HEROIC, an open-source software that allows participants to remotely collect advanced EEG data without the aid of an expert technician. The aim of HEROIC is to provide an open software platform that can be coupled with consumer grade wearables to record EEG data during customized neurocognitive tasks outside of traditional research environments. This article contains a description of HEROIC’s implementation, how it can be used by researchers and a proof-of-concept demonstration highlighting the potential for HEROIC to be used as a scalable and low-cost EEG data collection tool. Specifically, we used HEROIC to guide healthy participants through standardized neurocognitive tasks and captured complex brain data including event-related potentials (ERPs) and powerband changes in participants’ homes. Our results demonstrate HEROIC’s capability to generate data precisely synchronized to presented stimuli, using a low-cost, remote protocol without reliance on an expert operator to administer sessions. Together, our software and its capabilities provide the first democratized and scalable platform for large-scale remote and longitudinal analysis of brain health and disease.

AbstractBackgroundCoagulase-negativeStaphylococcusspecies are an emerging cause of intramammary infection, posing a significant economic and public health threat. The aim of this study was to assess the occurrence of coagulase-negativeStaphylococcusspecies in bovine milk and dairy farms in Northwestern Ethiopia and to provide information about their antibiotic susceptibility and virulence gene profiles.MethodsThe cross-sectional study was conducted from February to August 2022. Coagulase-negativeStaphylococcusspecies were isolated from 290 milk samples. Species isolation and identification were performed by plate culturing and biochemical tests and the antimicrobial susceptibility pattern of each isolate was determined by the Kirby-Bauer disc diffusion test. The single-plex PCR was used to detect the presence of virulent genes. The STATA software version 16 was used for data analysis. The prevalence, proportion of antimicrobial resistance and the number of virulent genes detected from coagulase-negativeStaphylococcusspecies were analyzed using descriptive statistics.ResultsCoagulase-negativeStaphylococcusspecies were isolated in 28.6%, (95% CI: 23.5–34.2) of the samples. Of these, theS. epidermidis,S. sciuri,S. warneri,S. haemolyticus,S. simulans,S. chromogens,S. cohnii, andS. captisspecies were isolated at the rates of 11, 5.2, 3.4, 3.1, 3.1, 1, 1, and 0.7% respectively. All the isolates showed a high percentage (100%) of resistance to Amoxicillin, Ampicillin, and Cefotetan and 37.5% of resistance to Oxacillin. The majority (54.2%) of coagulase-negative isolates also showed multidrug resistance. Coagulase-negative Staphylococcusspecies carried theicaD,pvl,mecA,hlb,sec, andhlavirulent genes at the rates of 26.5%, 22.1%, 21.7%, 9.6%, 9.6% and 8.4% respectively.ConclusionThe present study revealed that the majority of the isolates (54.2%) were found multidrug-resistant and carriage of one or more virulent and enterotoxin genes responsible for intramammary and food poisoning infections. Thus, urgent disease control and prevention measures are warranted to reduce the deleterious impact of coagulase-negative species. To the best of our knowledge, this is the first study in Ethiopia to detect coagulase-negativeStaphylococcusspecies with their associated virulent and food poisoning genes from bovine milk.

Abstract
Background
Developing novel germplasm by using wheat wild related species is an effective way to rebuild the wheat resource bank. The Psathyrostachys huashanica Keng (P. huashanica, 2n = 2x = 14, NsNs) is regarded as a superior species to improve wheat breeding because of its multi-resistance, early maturation and numerous tiller traits. Introducing genetic components of P. huashanica into the common wheat background is the most important step in achieving the effective use. Therefore, the cytogenetic characterization and influence of the introgressed P. huashanica large segment chromosomes in the wheat background is necessary to be explored.

Results
In this study, we characterized a novel derived line, named D88-2a, a progeny of the former characterized wheat-P. huashanica partial amphiploid line H8911 (2n = 7x = 49, AABBDDNs). Cytological identification showed that the chromosomal composition of D88-2a was 2n = 44 = 22II, indicating the addition of exogenous chromosomes. Genomic in situ hybridization demonstrated that the supernumerary chromosomes were a pair of homologues from the P. huashanica and could be stably inherited in the common wheat background. Molecular markers and 15 K SNP array indicated that the additional chromosomes were derived from the sixth homoeologous group (i.e., 6Ns) of P. huashanica. Based on the distribution of the heterozygous single-nucleotide polymorphism sites and fluorescence in situ hybridization karyotype of each chromosome, this pair of additional chromosomes was confirmed as P. huashanica 6Ns large segment chromosomes, which contained the entire short arm and the proximal centromere portion of the long arm. In terms of the agronomic traits, the addition line D88-2a exhibited enhanced stripe rust resistance, improved spike characteristics and increased protein content than its wheat parent line 7182.

Conclusions
The new wheat germplasm D88-2a is a novel cytogenetically stable wheat-P. huashanica 6Ns large segment addition line, and the introgressed large segment alien chromosome has positive impact on plant spikelet number and stripe rust resistance. Thus, this germplasm can be used for genetic improvement of cultivated wheat and the study of functional alien chromosome segment.

Abstract
Background
Conventional anesthesia used to reduce central venous pressure (CVP) during hepatectomy includes fluid restriction and vasodilator drugs, which can lead to a reduction in blood perfusion in vital organs and may counteract the benefits of low blood loss. In this study, we hypothesized that milrinone is feasible and effective in controlling low CVP (LCVP) during laparoscopic hepatectomy (LH). Compared with conventional anesthesia such as nitroglycerin, milrinone is beneficial in terms of intraoperative blood loss, surgical environment, hemodynamic stability, and patients’ recovery.

Methods
In total, 68 patients undergoing LH under LCVP were randomly divided into the milrinone group (n = 34) and the nitroglycerin group (n = 34). Milrinone was infused with a loading dose of 10 µg/kg followed by a maintenance dose of 0.2–0.5 µg/kg/min and nitroglycerin was administered at a rate of 0.2–0.5 µg/kg/min until the liver lesions were removed. The characteristics of patients, surgery, intraoperative vital signs, blood loss, the condition of the surgical field, the dosage of norepinephrine, perioperative laboratory data, and postoperative complications were compared between groups. Blood loss during LH was considered the primary outcome.

Results
Blood loss during hepatectomy and total blood loss were significantly lower in the milrinone group compared with those in the nitroglycerin group (P < 0.05). Both the nitroglycerin group and milrinone group exerted similar CVP (P > 0.05). Nevertheless, the milrinone group had better surgical field grading during liver resection (P < 0.05) and also exhibited higher cardiac index and cardiac output during the surgery (P < 0.05). Significant differences were also found in terms of fluids administered during hepatectomy, urine volume during hepatectomy, total urine volume, and norepinephrine dosage used in the surgery between the two groups. The two groups showed a similar incidence of postoperative complications (P > 0.05).

Conclusion
Our findings indicate that the intraoperative infusion of milrinone can help in maintaining an LCVP and hemodynamic stability during LH while reducing intraoperative blood loss and providing a better surgical field compared with nitroglycerin.

What role does compassion have on quality care ratings? A regression analysis and validation of the SCQ in emergency department patients
Authors: Boss Harrison , MacInnis Cara , Simon Roland , Jackson Jeanette , Lahtinen Markus , Sinclair Shane 
Published: July 2024

Abstract
Objective
To examine the unique contribution of patient reported experiences of compassion to overall patient quality care ratings. Additionally, we assess whether patients’ reported experiences of compassion in the emergency department differed between sociodemographic groups.

Methods
Provincial data for this cross-sectional study were collected from 03/01/2022 to 09/05/2022 from 14 emergency departments in Alberta, Canada. Data from 4501 emergency department patients (53.6% women, 77.1% White/European) were analyzed. The primary outcome was patients’ overall quality care ratings during their most recent ED visit. Measures included in the hierarchical stepwise regression included demographics, and those drawn from the Emergency Department Patient Experience of Care (EDPEC) questionnaire: single and multi-item measures of patient information (e.g., patient perceptions health) and patient experience (e.g., physician communication), and compassion (e.g., Sinclair Compassion Questionnaire; SCQ-ED).

Results
Data from 4501 ED patients were analysed. Stepwise hierarchical linear multiple regression indicated that of 21 included variables, compassion most strongly predicted overall quality care ratings (b=1.61, 95% CI 1.53-1.69, p<.001, f2=.23), explaining 19% unique variance beyond all other measures. One-way ANOVAs indicated significant demographic differences in mean compassion scores, such that women (vs. men) reported lower compassion (MD=-.15, 95% CI=-.21, -.09, p<.001), and Indigenous (vs. White) patients reported lower compassion (MD=-.17, 95% CI =-.34, -.01, p=.03).

Conclusions
Compassion was identified as a key contributor to ED overall quality care ratings, and experiences of compassion varied as a function of demographics. Patient-reported compassion is an indicator of quality care that needs to be formally integrated into clinical care and quality care assessments.
