Published: May 2022

Abstract
Background
The SF-6Dv2 classification system assesses health states in six domains—physical functioning, role function, bodily pain, vitality, social functioning, and mental health. Scores have previously been derived from the SF-36v2® Health Survey. We aimed to develop a six-item stand-alone SF-6Dv2 Health Utility Survey (SF-6Dv2 HUS) and evaluate its comprehensibility.

Methods
Two forms of a stand-alone SF-6Dv2 HUS were developed for evaluation. Form A had 6 questions with 5–6 response choices, while Form B used 6 headings and 5–6 statements describing the health levels within each domain. The two forms were evaluated by 40 participants, recruited from the general population. Participants were randomized to debrief one form of the stand-alone SF-6Dv2 HUS during a 75-min interview, using think-aloud techniques followed by an interviewer-led detailed review. Participants then reviewed the other form of SF-6Dv2 and determined which they preferred. Any issues or confusion with items was recorded, as was as overall preference. Data were analyzed using Microsoft Excel and NVivo Software (v12).

Results
Participants were able to easily complete both forms. Participant feedback supported the comprehensibility of the SF-6Dv2 HUS. When comparing forms, 25/40 participants preferred Form A, finding it clearer and easier to answer when presented in question/response format. The numbered questions and underlining of key words in Form A fostered quick and easy comprehension and completion of the survey. However, despite an overall preference for Form A, almost half of participants (n = 19) preferred the physical functioning item in Form B, with more descriptive response choices.

Conclusion
The results support using Form A, with modifications to the physical functioning item, as the stand-alone SF-6Dv2 HUS. The stand-alone SF-6Dv2 HUS is brief, easy to administer, and comprehensible to the general population.

Abstract
Background
Dyslexia is characterized by difficulties in spelling and reading. The aim of this study is to identify domains of cognitive strength and weakness of students with dyslexia and to study the effect of an especially designed computerized training program on their reading abilities. This study was conducted on 2nd-grade primary school students in Asyut city, Egypt (n = 560). Identification of students with dyslexia was done using Arabic Reading Achievement test and a newly constructed computerized Arabic Cognitive Abilities diagnostic battery for Reading (CADB-R). Training was applied using a newly constructed Computerized Cognitive abilities training battery for reading (CATB-R).

Results
The prevalence of dyslexia was 13.9% (N = 52/373), and it was higher among girls (15.8%) than boys (11.7%). After application of the training program, there was a significant increase in post-training mean scores of CADB-R score in their total and all sub-items.

Conclusions
All struggling readers should be included in well-tailored research-based rehabilitation programs.

Potential role of recombinant growth differentiation factor 11 in Alzheimer’s disease treatment
Authors: de Liyis Bryan Gervais , Halim Wilson , Widyadharma I. Putu Eka 
Published: May 2022

AbstractAlzheimer's disease (AD) is a neurodegenerative disease closely related to the accumulation of beta-amyloid (Aβ) plaques. Growth differentiation factor 11 (GDF11) is one of the proteins that play a role in the aggravation of AD. Decreased concentration of GDF11 disrupts regenerative nervous system, blood vessels, and various vital systems. Low levels of GDF11 with age can be overcome with recombinant GDF11 (rGDF11) to rejuvenate the regenerative effect. Based on research results, rGDF11 enhance the proliferation rate of neuronal precursor cells as well as angiogenesis. rGDF11 can replace lost levels of GDF11, overcome astrogliosis and activation of nerve cell microglia. Therapeutic effect of rGDF11 leads to an improved prognosis in AD patients by neurogenesis and angiogenesis. The prospects of rGDF11 in the treatment of AD have great potential for further research in the future.
Dramatic increase in volume versus length of invasive ductal carcinoma mimicking intramammary lymph node in a small nodular lesion
Authors: Aladag Kurt Seda , Celik Varol 
Published: May 2022

Abstract
Background
The tumor growth pattern in breast cancer appears to be variable and unpredictable. A minor increase in size in a pre-existing lesion, especially under 1 cm, corresponds to a more pronounced increase in volume.

Case presentation
We report a 63-year-old woman with a nodular density mimicking intramammary lymph node, diagnosed as invasive carcinoma of luminal B subtype. The lesion increased size and density over time in following mammograms until having indistinct margins. While the tumor volume was 12.7 mm3 at the first observation on mammography, it has increased approximately 6.7 times to reach 85.7 mm3 in four years. Finally, the patient diagnosed with early-stage breast cancer (T1N0M0) was treated with breast-conserving surgery.

Conclusions
Minor changes in size, density, and margin status of a lesion on serial mammograms are warning for breast cancer. Withal, a slight increase in lesion size in two dimensions can result in significant differences in volume. Therefore, comparative evaluation with previous mammograms and observing any difference in morphological features by screening are crucial for early diagnosis and optimal management of the disease.
Biosynthesis and optimization of highly stable gold nanoparticles, nanoconjugates, nanodrug conjugates and chitosan nanoconjugates using medicinal plants
Authors: Priya M. R. Kamala , Iyer Priya R. 
Published: May 2022

Abstract
Background
In the present study, the medicinal plants were exclusively selected based on their significant anti-HIV and anticancer activities. The green synthesis of gold nanoparticles was carried out using the 15 medicinal plant extracts on reduction with chloroauric acid. The present study also focused on a novel pharmacognostic approach over the usage of plants source. The nanoparticle synthesized through medicinal plants possessed the potential therapeutic properties of the plants. The resultant nanoparticle carried the attributes of a nanomaterial alongside the phytoactivity.

Results
Initially, individual nanoparticle (NP) was synthesized through a single plant extract and studied for its effective anti-HIV and anticancer activity. Finally, a nanoconjugate (NC) comprising of the 3 extracts (trio extract) in one nanoparticle was synthesized. The nanoparticles which exhibited comparatively high anti-HIV and anticancer activity were chosen for the synthesis of nanoconjugate, thereby achieving a synergistic anticancer and anti-HIV activity. Further, a nanodrug conjugate (NDC) was prepared in combination of AuNPs and the chemotherapeutic drug, doxorubicin (Dox) for cancer and AuNPs with antiretroviral drug azidothymidine (AZT) for HIV.

Conclusions
A nanodrug conjugate helps to enhance the efficiency of the drug. The nanodrug conjugate brings about a combinatorial effect of the nanomaterials and the drug. Further, a biocompatible nanocarrier was developed as a conjugate with chitosan and gold nanoparticles using STPP as gelating agent for the drug doxorubicin. The synthesis reaction was optimized under various underlying parameters. The gold nanoparticles proved to be stable at high temperature and different buffers and ensured to be a safe option for bioassays and in vivo applications. Upon storing the synthesized AuNPs at different storage conditions, the nanoparticles were observed to be highly stable for a period of more than 48 months. The present study resulted in biosynthesis of highly stable gold nanoparticles using medicinal plant extracts as reducing and stabilizing agents.

Published: May 2022

AbstractSystemic necrosis, induced by plant virus-derived elicitors, is considered as one of the most severe symptoms. It has never been reported that the elicitors encoded by wheat yellow mosaic virus (WYMV) can induce systemic necrosis in plant. In this study, we discovered that the WYMV-encoded 14K protein localized to the endoplasmic reticulum (ER) membrane and triggered a necrotic symptom in Nicotiana benthamiana at 5 days post-infiltration (dpi). Meanwhile, overexpression of WYMV 14K suppressed the replication of tobacco rattle virus (TRV) and potato virus X (PVX). Additionally, deletion of the transmembrane domain and substitution of two non-conserved regions in 14K resulted in the loss of the ability of this protein to induce systemic necrosis. Moreover, the 14K homologous proteins of other bymoviruses failed to induce systemic necrosis. Our results, for the first time, reveal that WYMV 14K induces systemic necrosis and suppresses the replication of other viruses.

AbstractCeviche is present in all the Pacific coast of Latin America. Its origin and history are still debated. The consensus is that it arises from creolization between local and Eurasian ingredients and techniques. Ecuadorian ceviche is both traditional and iconic, present in one form or another in its twenty-four provinces, adapting to the availability of products and becoming part of the identity of regions, parishes, and cities. The objective of this work is to confirm ceviche as a traditional Ecuadorian dish, to assess the most popular types of Ecuadorian ceviche, condiments and sides, and also to glimpse the wide variety of preparations that appear through adaptation to ingredient availability and food customs. We performed a review of both scientific and gray literature, a relative search volume analysis and a survey among culinary professionals (n = 403). The most popular in Ecuador is shrimp (Litopenaeus vannamei) ceviche with 54% of the responses, followed by fish, regardless of species (29%), and both lupin (Lupinus mutabilis) and black clam (Anadara tuberculosa) with 5%. The most utilized condiments are onion, lemon juice and cilantro a “holy trinity” with more than 90% usage. These results are in good agreement with those provided by Web search volumes. The variety of main ingredients, condiments and sides is ample, though, and suggests further research. Sustainability concerns related to ceviche are the sustainability of shrimp farming and fish capture, and the preservation of mollusks and their ecosystems.

AbstractRheumatoid arthritis (RA) is a chronic autoimmune disorder affecting joints with a hallmark of autoantibody production. Mannan-enhanced collagen type II (COL2) antibody induced arthritis (mCAIA) in neutrophil cytosolic factor 1(Ncf1) mutation mouse is a chronic disease model imitating RA in mice. In this study, we characterize the chronic phase of mCAIA in Ncf1 mutated (BQ.Ncf1m1j/m1j) mice. Arthritis was induced by an intravenous injection of anti-COL2 monoclonal antibodies on day 0 followed by intra-peritoneal injections of mannan (from Saccharomyces cerevisiae) on days 3 and 65 in BQ.Ncf1m1j/m1j and BQ mice. Bone erosion was analysed by computed tomography (CT) and blood cell phenotypes by flow cytometry. Cytokines and anti-COL2 antibodies were analyzed with multiplex bead-based assays. The arthritis in the Ncf1m1j/m1j mice developed with a chronic and relapsing disease course, which was followed for 200 days and bone erosions of articular joints were evaluated. An increased number of circulating CD11b+ Ly6G+ neutrophils were observed during the chronic phase, together with a higher level of G-CSF (granulocyte colony-stimulating factor) and TNF-α. In conclusion, the chronic relapsing arthritis of mCAIA in the Ncf1m1j/m1j mice develop bone erosions associated with a sustained neutrophil type of inflammatory responses.

Authors: Brown Penelope , Bakolis Ioannis , Appiah-Kusi Elizabeth , Hallett Nicholas , Hotopf Matthew , Blackwood Nigel 
Published: May 2022

Background
Psychiatric morbidity in prisons and police custody is well established, but little is known about individuals attending criminal court. There is international concern that vulnerable defendants are not identified, undermining their right to a fair trial.

Aims
To explore the prevalence of a wide range of mental disorders in criminal defendants and estimate the proportion likely to be unfit to plead.

Method
We employed two-stage screening methodology to estimate the prevalence of mental illness, neurodevelopmental disorders and unfitness to plead, in 3322 criminal defendants in South London. Sampling was stratified according to whether defendants attended court from the community or custody. Face-to-face interviews, using diagnostic instruments and assessments of fitness to plead, were administered (n = 503). Post-stratification probability weighting provided estimates of the overall prevalence of mental disorders and unfitness to plead.

Results
Mental disorder was more common in those attending court from custody, with 48.5% having at least one psychiatric diagnosis compared with 20.3% from the community. Suicidality was frequently reported (weighted prevalence 71.2%; 95% CI 64.2–77.3). Only 16.7% of participants from custody and 4.6% from the community were referred to the liaison and diversion team; 2.1% (1.1–4.0) of defendants were estimated to be unfit to plead, with a further 3.2% (1.9–5.3) deemed ‘borderline unfit’.

Conclusions
The prevalence of mental illness and neurodevelopmental disorders in defendants is high. Many are at risk of being unfit to plead and require additional support at court, yet are not identified by existing services. Our evidence challenges policy makers and healthcare providers to ensure that vulnerable defendants are adequately supported at court.

Abstract

Context
The Arg16 variant in the β2-receptor gene is associated with increased risk of severe hypoglycemia in subjects with type 1 diabetes mellitus.

Objective
We hypothesized that the Arg16 variant is associated with decreased metabolic and symptomatic responses to recurrent hypoglycemia.

Methods
Twenty-five healthy male subjects selected according to ADRB2 genotype and being homozygous for either Arg16 (AA; n = 13) or Gly16 (GG; n = 12) participated in 2 consecutive trial days with 3 periods of hypoglycemia (H1-H3) induced by a hyperinsulinemic hypoglycemic clamp. The main outcome measure was mean glucose infusion rate (GIR) during H1-H3.

Results
During H1-H3, there was no difference between AA or GG subjects in GIR, counter-regulatory hormones (glucagon, epinephrine, cortisol, growth hormone), or substrate levels of lactate, glycerol, and free fatty acids (FFAs), and no differences in symptom response score or cognitive performance (trail making test, Stroop test). At H3, lactate response was reduced in both genotype groups, but AA subjects had decreased response (mean ± standard error of the mean of area under the curve) of glycerol (–13.1 ± 3.8 μmol L–1 hours; P = .0052), FFA (–30.2 ± 11.1 μmol L–1 hours; P = .021), and β-hydroxybutyrate (–0.008 ± 0.003 mmol L–1 hour; P = .027), while in GG subjects alanine response was increased (negative response values) (–53.9 ± 20.6 μmol L–1 hour; P = .024).

Conclusion
There was no difference in GIR between genotype groups, but secondary outcomes suggest a downregulation of the lipolytic and β-hydroxybutyrate responses to recurrent hypoglycemia in AA subjects, in contrast to the responses in GG subjects.

AbstractContextPatients with radioactive iodine (RAI) refractory metastatic differentiated thyroid cancer (DTC) have poor prognosis. Early identification of RAI refractoriness may improve care.ObjectiveThis work aimed to characterize DTC patients with distant metastases (DM) at diagnosis who presented with non–iodine-avid disease.MethodsRetrospective analyses of DTC patients with DM at diagnosis who presented between 2012 and 2020 were performed. Iodine uptake in DM was correlated with tumor histology and mutational profile. The difference in uptake between BRAFV600E-like (BVL) and RAS-like (RL) cancers based on insights from The Cancer Genome Atlas was evaluated.ResultsAmong 78 patients, 48.7% had negative uptake in DM on the first posttherapy scan. Negative scans were highly prevalent in papillary thyroid carcinoma (PTC) with papillary architecture, PTC with BRAFV600E mutation, and PTC with both BRAFV600E and TERT promoter mutations (71.1%, 80.9%, and 100%, respectively). BVL and RL tumors exhibited distinct uptake patterns with negative scan prevalence of 76.9% and 14.3% (P = .005). Multivariate logistical regression confirmed high odds of negative uptake in BVL tumors with either BVL mutations or papillary architecture, 19.8 (95% CI, 2.72-144), and low odds of negative uptake in RL tumors with either RL mutations or follicular architecture, 0.048 (95% CI, 0.006-0.344), after adjusting for age, sex, race, RAI preparation method, bone metastases, and RAI dose. Patients with negative scans were significantly older (62.4 vs 47.0 years, P = .03).ConclusionAmong DTC patients with DM at diagnosis, non–iodine-avid disease is highly prevalent in patients with BVL cancers, particularly with BRAFV600E and TERT promoter mutations, and is associated with an older age. Better strategies are needed to improve RAI treatment response for these patients.
Comparison of Antinociceptive Properties Between Sevoflurane and Desflurane Using Pupillary Dilation Reflex Under Equivalent Minimum Alveolar Concentration: A Randomized Controlled Trial

Published: May 2022

BACKGROUND:
The pupillary dilation reflex (PDR), the change in pupil size after a nociceptive stimulus, has been used to assess antinociception during anesthesia. The aim of this study was to compare the antinociceptive properties of sevoflurane and desflurane by measuring the PDR amplitude.

METHODS:
Seventy patients between 20 and 55 years of age were randomly allocated to receive either sevoflurane or desflurane. The PDR amplitude after an electrical standardized noxious stimulation (SNT) was measured using an infrared pupillometer under 1.0 minimum alveolar concentration (MAC). The pupil diameter was measured from 5 seconds before to 5 minutes after the SNT. The mean arterial pressure (MAP), heart rate (HR), and bispectral index (BIS) were also measured immediately before and after SNT as well as 1 minute and 5 minutes after SNT. The primary outcome was the maximum percent increase from the prestimulation value of the pupil diameter, and the secondary outcomes were the maximum percent increase from the prestimulation value of the MAP, HR, and BIS after SNT.

RESULTS:
The maximum percent increase of the pupil diameter after SNT was not different between the 2 groups (median [first quartile to third quartile], 45.1 [29.3–80.3] vs 43.4 [27.0–103.1]; median difference, −0.3 [95% confidence interval, −16.0 to 16.5]; P = .986). Before SNT, the MAP was higher under 1.0 MAC of sevoflurane than desflurane; however, the maximum percent increase of MAP, HR, and BIS was not different between the 2 groups.

CONCLUSIONS:
The amount of change in the PDR amplitude, MAP, and HR after SNT was not different between sevoflurane and desflurane anesthesia. This result might suggest that sevoflurane and desflurane may not have different antinociceptive properties at equivalent MAC.
The extra-embryonic space and the local contour are crucial geometric constraints regulating cell arrangement
Authors: Seirin-Lee Sungrim , Yamamoto Kazunori , Kimura Akatsuki 
Published: May 2022

ABSTRACT
In multicellular systems, cells communicate with adjacent cells to determine their positions and fates, an arrangement important for cellular development. Orientation of cell division, cell-cell interactions (i.e. attraction and repulsion) and geometric constraints are three major factors that define cell arrangement. In particular, geometric constraints are difficult to reveal in experiments, and the contribution of the local contour of the boundary has remained elusive. In this study, we developed a multicellular morphology model based on the phase-field method so that precise geometric constraints can be incorporated. Our application of the model to nematode embryos predicted that the amount of extra-embryonic space, the empty space within the eggshell that is not occupied by embryonic cells, affects cell arrangement in a manner dependent on the local contour and other factors. The prediction was validated experimentally by increasing the extra-embryonic space in the Caenorhabditis elegans embryo. Overall, our analyses characterized the roles of geometrical contributors, specifically the amount of extra-embryonic space and the local contour, on cell arrangements. These factors should be considered for multicellular systems.
