Theory of mind in adolescents with Attention-Deficit Hyperactivity Disorder: A cross-sectional study

Objective Attention-Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder that may be associated with impaired Theory of Mind (ToM) and social cognition. ToM is a domain in social cognition, referring to one’s ability to attribute beliefs, intents, perspectives, and understandings to oneself or others and to understand others’ mental states. Materials & Methods The present study enrolled 52 ADHD of adolescents and 41 healthy age-matched controls in this study. This study applied The Reading the Mind in The Eyes Task (RMET) and Theory of Mind Assessment Scale (Th.o.m.a.s.) for all participants. The results of these tasks were compared between the two study groups. Results No significant differences were found between these two study groups regarding ToM abilities using mean scores in the Th.o. m.a.s. inventory and the RMET. Furthermore, no association was found between the mean score in the ToM (in both study groups) and this study’s parameters of gender, mean age, birth rank, family structure, and income. Conclusion This study did not support the hypothesis that adolescents with ADHD perform worse on ToM tasks.
Evaluation and Management of Postsurgical Patient With Hirschsprung Disease Neurogastroenterology & Motility Committee: Position Paper of North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN)

Children with Hirschsprung disease have postoperative long-term sequelae in defecation that contribute to morbidity and mortality and significantly impact their quality of life. Pediatric patients experience ongoing long-term defecation concerns, which can include fecal incontinence (FI) and postoperative obstructive symptoms, such as constipation and Hirschsprung-associated enterocolitis. The American Pediatric Surgical Association has developed guidelines for management of these postoperative obstructive symptoms and FI. However, the evaluation and management of patients with postoperative defecation problems varies among different pediatric gastroenterology centers. This position paper from the Neurogastroenterology & Motility Committee of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition reviews the current evidence and provides suggestions for the evaluation and management of postoperative patients with Hirschsprung disease who present with persistent defecation problems.
Association between Moral Distress and Burnout Syndrome in university-hospital nurses

Abstract Objective: to analyze the association between moral distress and Burnout Syndrome among nurses in a university hospital. Method: descriptive, analytical study conducted with 269 nurses working in a university hospital located in Rio Grande do Sul, Brazil. Data were collected in person in 2019 by previously trained collectors. A sociodemographic and employment questionnaire, the Brazilian Scale of Moral Distress in Nurses and the Maslach Burnout Inventory were applied. Descriptive and analytical statistical analysis was used. Results: an association was identified between moral distress intensity and frequency and its dimensions with Burnout Syndrome and its dimensions. Nurses with low professional achievement and high emotional exhaustion showed a higher prevalence of moral distress. Conclusion: an association between moral distress and Burnout Syndrome, as well as between their dimensions, was evidenced. The results suggest the need to investigate urgent interventions to mitigate the situations and manifestations of moral distress and Burnout Syndrome by developing strategies for workers’ health.
Stagnating rates of blood pressure control in Australia: insights from opportunistic screening of 10 046 participants of the May Measurement Month campaigns

Background: Raised blood pressure (BP) remains the single most important modifiable risk factor contributing to cardiovascular and all-cause mortality in Australia and worldwide. May Measurement Month, a global BP measurement and screening campaign initiated by the International Society of Hypertension and carried out in Australia since its inception in 2017, aimed at obtaining standardized BP measurements from members of the community to increase awareness of high BP and its associated risks. Method: Adults participants (≥18 years) were recruited through opportunistic sampling across Australia during the month of May in 2017, 2018 and 2019. Trained volunteers recorded BP readings in a standardized manner and collected data on demographic, lifestyle factors and comorbidities. Hypertension was defined as SBP of at least 140 mmHg, or DBP of at least 90 mmHg, or taking antihypertensive medication. Data were collated centrally and analysis was carried out using regression models to evaluate the associations between BP and participant characteristics. Results: A total of 10 046 participants were screened, of whom 3097 (31.0%) had hypertension, only 48.5% were aware of their condition and 44.4% were taking antihypertensive medication. Of those taking antihypertensive medication, 53.2% were controlled to less than 140/90 mmHg, whereas the remaining 46.8% of participants had BP of at least 140/90 mmHg suggestive of inadequately treated hypertension. Conclusion: Consecutive data obtained over a 3-year period in Australia demonstrated stagnating awareness, treatment and control rates with the latter two being substantially lower than global rates and those in other high-income countries. Concerted efforts from all stakeholders will be required to help overcome the unacceptably poor rates of BP treatment and control in Australia.
Rate of energy gain and maximum energy in diffusive shock acceleration

The problem of diffusive shock acceleration of fast charged particles is reexamined with emphasis on the rate of energy gain, and the maximum energy which can be attained in a given circumstance. The direction of the average magnetic field at the shock is shown to have a large effect. If the perpendicular diffusion coefficient is much smaller than the parallel coefficient, particles can gain much more energy if the shock is quasi-perpendicular than if it is quasi-parallel. The maximum energy attainable can be substantially higher (by a factor of 100 or more) than previous discussions would predict, in cases where the shock is quasi-perpendicular. The energy gain increases as kappa-perpendicular decreases. The principal limitation comes from the requirement that diffusion be a valid approximation to the particle motion, and that the particle be able to diffuse fast enough to encounter the shock many times. 29 references.
Ramsay-Curve Differential Item Functioning

Differential item functioning (DIF) occurs when an item on a test, questionnaire, or interview has different measurement properties for one group of people versus another, irrespective of true group-mean differences on the constructs being measured. This article is focused on item response theory based likelihood ratio testing for DIF (IRT-LR or IRT-LR-DIF). Historically, the models have been fitted assuming the latent variables for both reference and focal groups are normal, but this is unnecessary. A new variation, called Ramsay-curve DIF (RC-DIF), is introduced here. In RC-DIF, the latent density for both groups is estimated simultaneously with the item parameters. Similar approaches in which the density for only one group is estimated, or the densities are estimated as empirical histograms (EHs), are also studied. Free software is available from the author to test each item individually for DIF with the latent densities estimated as EHs or RCs. A simulation study shows that these methods improve results compared with assuming normality mistakenly, and an empirical example illustrates the procedures.
Pharmacological treatment of bipolar disorder in pregnancy: An update on safety considerations

Pregnancy in women with bipolar disorder (BD) can be considered a high-risk pregnancy in view of several clinical and pharmacotherapeutic considerations. Pharmacological treatment during pregnancy requires a careful weighing of psychotropic drug exposure against the risk of BD relapse. An untreated bipolar illness can negatively affect the health of mother as well as unborn child in the event of a relapse. Availability of well balanced, latest information on safety of prophylactic drugs for BD is crucial for making informed decisions. The review provides an evidence-based update (2015–2021) on the drug safety considerations involved in providing care for women with BD who are either pregnant or planning to conceive in near future. Literature review based on systematic reviews, meta-analyses, and data available from studies based on large-scale cohorts and birth registries has been synthesized and presented along with clinically relevant recommendations.
Tethered cord syndrome in KBG syndrome

Tethered cord syndrome (TCS) is characterized by leg pain and weakness, bladder and bowel dysfunction, orthopedic malformations such as scoliosis, and motor deficits caused by the fixation of the spinal cord to surrounding tissues. TCS is surgically treatable and often found in conjunction with other syndromic conditions. KBG syndrome is caused by variants in the ANKRD11 gene and is characterized by short stature, developmental delay, macrodontia, and a triangular face. The current study explores the prevalence of TCS in pediatric KBG patients and their associated signs and symptoms. Patients with KBG were surveyed for signs and symptoms associated with TCS and asked if they had been diagnosed with the syndrome. We found a high proportion of patients diagnosed with (11%) or being investigated for TCS (24%), emphasizing the need to further characterize the comorbid syndromes. No signs or symptoms clearly emerged as indicative of TCS in KBG patients, but some the prevalence of some signs and symptoms varied by sex. Male KBG patients with diagnosed TCS were more likely to have coordination issues and global delay/brain fog than their female counterparts. Understanding the presentation of TCS in KBG patients is critical for timely diagnosis and treatment.
Understanding Nanocellulose–Water Interactions: Turning a Detriment into an Asset

Modern technology has enabled the isolation of nanocellulose from plant-based fibers, and the current trend focuses on utilizing nanocellulose in a broad range of sustainable materials applications. Water is generally seen as a detrimental component when in contact with nanocellulose-based materials, just like it is harmful for traditional cellulosic materials such as paper or cardboard. However, water is an integral component in plants, and many applications of nanocellulose already accept the presence of water or make use of it. This review gives a comprehensive account of nanocellulose–water interactions and their repercussions in all key areas of contemporary research: fundamental physical chemistry, chemical modification of nanocellulose, materials applications, and analytical methods to map the water interactions and the effect of water on a nanocellulose matrix.
A search for aliquot cycles and amicable pairs

A search for aliquot cycles below 3.6* 1010 and amicable pairs below 1011 is described. Three new cycles of length 4 and one new cycle of length 6 are exhibited. Four triples of amicable pairs with the same pair-sum are also exhibited. The idea of an aliquot cycle is an extension of the concepts of perfect numbers and amicable pairs, which are aliquot cycles of lengths 1 and 2, respectively. Let ar(n) be the sum of the divisors of n , where n is a natural number. Define s(n) to be the sum of the divisors of n exclusive of n, that is, s(n) = ar(n) n . An aliquot cycle of length k is then a finite sequence of distinct natural numbers (a,, ., ak) such that al = s(ak), and for each i = 1, . , k 1, aj+j = s(ai). In an earlier paper [7] we described a search for aliquot cycles that covered some of the cycles with length 32 or less and smallest element below 1010. A. Flammenkamp [5] recently reported a search for aliquot cycles that covered some of the cycles with length 50 or less and smallest element below 5 * 109. To date, including the results of these searches, 35 cycles with length at least 3 are known, 30 of length 4, two of length 8, and one each of lengths 5, 9, and 28 [1, 2, 4, 5, 7, 8, 13]. In this paper we describe a new search to find all aliquot cycles, of any length, such that the element preceding the largest element of the aliquot cycle does not exceed 3.6. 1010, and all amicable pairs with smaller element not exceeding 1011 In the aliquot cycle search, the method used was similar to that used in the third search in [7]. For all a1 between 2 and 3.6. 1010, a2 = s(al) was constructed. The number a2 was then the putative largest member of the aliquot cycle; hence if a2 was less than a1 , the search stopped immediately. Otherwise, ai = s(ai-1) was constructed for i = 3, 4, and so on. If ai ever became equal to a1, iteration stopped and a new aliquot cycle was recorded. On the other hand, if ai became equal to 1, ai exceeded a2, the sequence of ai's fell into a cycle of length dividing 4 not involving a1, ai equalled 12496, the smallest member of the only known aliquot cycle of length 5, or ai equalled 14316, the smallest member of the only known aliquot cycle of length 28, iteration stopped and a new cycle was not recorded. If i became equal to 5001, iteration stopped Received by the editor May 19, 1992. 1991 Mathematics Subject Classification. Primary 11A25; Secondary 11-04.
Lateral encroachment of Ni-silicides in the source/drain regions on ultrathin silicon-on-insulator

Lateral growth of Ni silicide towards the channel region of metal-oxide-semiconductor transistors (MOSFETs) fabricated on ultrathin silicon-on-insulator (SOI) is characterized using SOI wafers with a 20-nm-thick surface Si layer. With a 10-nm-thick Ni film for silicide formation, p-channel MOSFETs displaying ordinary device characteristics with silicided p+ source/drain regions were demonstrated. No lateral growth of NiSix under gate isolation spacers was found according to electron microscopy. When the Ni film was 20 nm thick, Schottky contact source/drain MOSFETs showing typical ambipolar characteristics were obtained. A severe lateral encroachment of NiSix into the channel region leading to an increased gate leakage was revealed, while no detectable voiding at the silicide front towards the Si channel was observed.
Body Composition Predictors of Complicated Crohn's Disease

Background: High visceral adipose tissue (VAT) and creeping fat (CrF) in Crohn’s disease (CD) have been widely recognized. The VAT to subcutaneous adipose tissue (SAT) ratio and sarcopenia have been associated with CD complications. Studies regarding the influence of body composition predictors on CD complications assessed with magnetic resonance enterography (MRE) are scarce. Aim: The aim of this study was to assess body composition parameters and CrF in opportunistic MRE as predictors of complicated CD. Methods: This was a retrospective study of 114 patients with inflammatory (n = 54) and complicated (n = 60) CD. The semiautomated assessment of body composition and the qualitative evaluation of CrF were performed. Results: Body composition parameters did not differ between both groups regarding the body mass index (p = 0.50), total adipose tissue index (TATI) (p = 0.14), subcutaneous adipose tissue index (SATI) (p = 0.17), visceral adipose tissue index (VATI) (p = 0.33), VAT/SAT ratio (p = 0.77), intramuscular adipose tissue (p = 0.64), skeletal muscle index (p = 0.22), and sarcopenia (p = 0.50). 47 strictures, 18 fistulae, and seven abscesses were identified. Fistulae were more likely to occur in patients with CrF (odds ratio [OR] 5.07, 95% confidence interval [CI] 1.76–14.56; p=<0.001) and high VAT/SAT ratio (OR: 3.82, 95% CI 1.34–10.85; p = 0.01). Conclusion: Body composition measurements in CD patients displayed no statistically significant difference between the groups of inflammatory and complicated disease. Nonetheless, CD patients stratified in the group of high VAT/SAT ratio and the presence of CrF should be recognized as risk groups for the occurrence of fistulae.
The impact of COVID-19 pandemic on the dynamic HIV care engagement among people with HIV: real-world evidence

Introduction: Existing studies examining the impact of the COVID-19 pandemic on engagement in HIV care often capture cross-sectional status, while lacking longitudinal evaluations. This study examined the impact of the pandemic on the longitudinal dynamic change of retention in care and viral suppression status. Methods: The electronic health record (EHR) data of this population-level cohort study were retrieved from the statewide electronic HIV/AIDS reporting system in South Carolina. The study population was people with HIV (PWH) who had at least one year's symmetric follow-up observation record before and after the pandemic. Multivariable generalized linear mixed regression models were employed to analyze the impact of the pandemic on these outcomes, adjusting for socio-demographic characteristics and preexisting comorbidities. Results: In the adjusted models, PWH had a lower likelihood of retention in care (adjusted odds ratio [aOR]: 0.806, 95% confidence interval [CI]: 0.769, 0.844) and a higher probability of virological failure (aOR: 1.240, 95% CI: 1.169, 1.316) during the peri-pandemic period than pre-pandemic period. Results from interaction effect analysis from each cohort revealed that the negative effect of the pandemic on retention in care was more severe among PWH with high comorbidity burden than those without any comorbidity; meanwhile, a more striking virological failure was observed among PWH who reside in urban areas than in rural areas. Conclusion: The COVID-19 pandemic has a negative impact on retention in care and viral suppression among PWH in South Carolina, particularly for individuals with comorbidities and residing in urban areas.
Immunostaining patterns reveal potential morphogenetic role of Toll-like receptors 4 and 7 in the development of mouse respiratory system, liver and pancreas

Toll-like receptors (TLRs) are the mammalian ortholog of Drosophila melanogaster protein Toll, originally identified for its involvement in embryonic development. In mammals, TLRs are mainly known for their ability to recognize pathogen- or damage-associated molecular patterns and, consequently, to initiate the immune response. However, it is becoming clear that TLRs can play a role also in mammal embryo development. We have previously described TLR4 and TLR7 expression in developing mouse peripheral nervous system and gastrointestinal tract. In the present study, we extended the investigation of TLR4 and TLR7 to the respiratory system and to the two main accessory organs of the digestive system, the liver and pancreas. TLR4 and TLR7 immunostaining was performed on mouse conceptuses collected at different stages, from E12 to E18. TLR4 and TLR7 immunoreactivity was evident in the embryo pancreas and liver at E12, while, in the respiratory apparatus, appeared at E14 and E17, respectively. Although further studies are required to elucidate the specific role of these TLRs in embryo development, the differential spatiotemporal TLR4 and TLR7 appearance may suggest that TLR expression in developing embryos is highly regulated for a possible their direct involvement in the formation of the organs and in the acquisition of immune-related features in preparation for the birth.
Morphological and cytochemical characteristics of Varanus niloticus (Squamata, Varanidae) blood cells

Varanus niloticus is a lizard residing within the Varanidae family. To date no studies detailing its blood morphology and characteristics have been conducted. This study used histologically stained blood and bone marrow samples to visualize the cells and their characteristics. The erythrocytes were nucleated, these nuclei were located in the middle of the elliptical cells. Hemoglobin filled the erythrocyte cytoplasm. Eosinophils were large cells with lobed nuclei and spherical acidophilic granules. Large granulocytes called heterophils were present and characterized by their fusiform/pleomorphic cytoplasmic granules. Small spherical granulocytes, known as basophils, presented with round, deeply stained metachromatic granules that gave the cytoplasm a dusty or cobblestoned appearance which was able to cover the nucleus, which in turn had an unusual shape. Thrombocytes ranged in shape from ellipsoidal to fusiform. They featured an elliptical, centrally located nucleus and a pale cytoplasm, with small vacuoles, and fine acidophilic granulation. The smallest variety of non‐granular leukocytes was the lymphocytes. Their cytoplasm was sparse, finely granular, light blue, had tiny cytoplasmic projections, featuring a high nucleus: cytoplasm ratio. Larger and smaller sized populations of lymphocytes were distinguished, with the larger cells similar in size to azurophils. In general, the pleomorphic monocytes were the biggest mononuclear leucocytes, displaying cytoplasmic projections. Their nuclei were ovoid, kidney‐ or bean‐shaped, with vacuolated and granular cytoplasms. Round cells were common among the monocytic azurophils, and they had a granular cytoplasm, and their nuclei were typically eccentric. The present research identifies the cell types and morphologies within the Varanus niloticus.
The biological role of charge distribution in linear antimicrobial peptides

ABSTRACT Introduction Antimicrobial peptides (AMP) have received particular attention due to their capacity to kill bacteria. Although much is known about them, peptides are currently being further researched. A large number of AMPs have been discovered, but only a few have been approved for topical use, due to their promiscuity and other challenges, which need to be overcome. Areas covered AMPs are diverse in structure. Consequently, they have varied action mechanisms when targeting microorganisms or eukaryotic cells. Herein, the authors focus on linear peptides, particularly those that are alpha-helical structured, and examine how their charge distribution and hydrophobic amino acids could modulate their biological activity. Expert opinion The world currently needs urgent solutions to the infective problems caused by resistant pathogens. In order to start the race for antimicrobial development from the charge distribution viewpoint, bioinformatic tools will be necessary. Currently, there is no software available that allows to discriminate charge distribution in AMPs and predicts the biological effects of this event. Furthermore, there is no software available that predicts the side-chain length of residues and its role in biological functions. More specialized software is necessary
