The unfortunate global outbreak of COVID-19 has had many implications in different aspects of public health, particularly mental and psychological wellbeing. Psychosis, or more specifically, schizophrenia, is a mental disorder of perplexing etiology, that has been said to occur partly due to genetic predisposition. Now amid the COVID-19 pandemic, new evidence suggests that there might be a genetic link between schizophrenia and SARS-CoV-2, the cause of COVID-19, that could have implications in the area of schizophrenia research.

Introduction: The creation of the “open cavity” to clear cholesteatoma results in significant morbidity in over a third of patients. Various biological and non-biological materials have been used to reduce or obliterated these mastoid cavities. Materials and Methods: This study reports the technique and results of using hydroxyapatite granules with a pericranial flap to obliterate troublesome cavities. Results: 50 mastoid obliterations were performed in 48 patients. 94% no longer required water precautions 2 months post-operatively and may use conventional hearing aids. Discussion: This technique improves patients’ quality of life and can enable discharge of patients previously reliant on ENT services.

Global warming is already affecting plant phenology, growth and reproduction. A wide range of evidence indicates warming effects on reproductive and vegetative traits, as well as phenology, but seldom do studies assess these traits in concert and across the whole of a plant's life cycle, particularly in wild species. Further, while there is evidence that these effects vary between species little is known about the extent of within-species variation for plant persistence under future warming scenarios. We assessed trait variation in response to warming in Oreomyrrhis eriopoda, an Australian native montane herb, in which within-species variation in germination strategy and growth characteristics has been demonstrated. We quantified associations between developmental trajectories and population-level variation in germination timing and examined whether the next-generation traits are altered by maternal growth conditions. Warming effects were expressed in different traits during different developmental stages. The effect of warming varied as a function of germination strategy, but germination strategy itself was conserved across generations. Thus, we conclude that understand the response of wild species to warming takes a whole-of-life perspective and attention to ecologically significant patterns of within species variation.

Objective: To analyze the clinical manifestations of a huge inverted T wave and to summarize the causes of misdiagnosis of deformed papillary muscle as myocardial ischemia. Cases and Results: A retrospective analysis of the clinical data of 215 patients with 12-lead ECG T wave inverted myocardial ischemia from 2006 to 2018 in our hospital. Combined with multi-factor logistic regression analysis of echocardiography and electrocardiogram, we evaluated 11 cases of unique clinical malformed papillary muscles with lowered position. The electrocardiogram showed sinus rhythm, the electrocardiogram axis was normal, and the T wave inversion was 6-10 mm. The angiography showed no abnormalities. The echocardiogram showed that the left ventricular wall structure, motion, and left ventricular ejection fraction were within the normal range. Echocardiography showed that the anterolateral papillary muscle base of 11 patients originated from the apex 1/3. A 12-lead ECG with deformed papillary muscles shows that a huge inverted T wave is not a feature of myocardial ischemia. In this case, the 12-lead ECG feature is insufficient to identify the cause of myocardial ischemia. Therefore, we must exclude these myocardial ischemia in order to diagnose and treat correctly. Conclusion: Conventional 12-lead electrocardiogram shows that the giant inverted T wave of the deformed papillary muscles is diagnosed as myocardial ischemia, which is a misdiagnosis.

Particle selectivity plays an important role in clarifying sediment transport processes in vegetative filter strips (VFS). 10-m long grass strips at slopes of 5○ and 15○were subjected to a series of silt-laden inflows experiments with different particle sizes to investigate the sediment transport and its response to overland flow hydraulics. The inflow sediments came from local soil, river-bed sand, and mixed, with median particle size d50 of 39.9, 207.9, and 77.4 μm, respectively. Three independent repeated experiments were carried for each treatment. The results show that when the sediment trapping lasted for a certain length of time, the re-entrainment of some small-sized particles was greater than the deposition; that is, negative deposition occurred, which was not erosion of the original soil. Negative deposition of particles is mainly determined by the particle diameter. The coarser the inflow sediment particles and/or the steeper the slope, the coarser the particles can be negatively deposited. Deposited sediment causes the VFS bed surface to become smooth and hydraulic resistance decrease exponentially. Stream power P is more suitable than shear stress τ of overland flow to be used to describe the process of sediment particle transport in VFS. The relationship between P and d50 of outflow sediment is very consistent with the form of power function with a constant term. These results are helpful to understand the physical process of sediment transport on vegetation hillslopes.

Negli ultimi tempi, soprattutto in seguito alla diffusione del Covid-19, si  è affermata l'importanza del trattamento terziario delle acque reflue a causa della persistenza dei prodotti farmaceutici e dei virus nelle acque anche dopo i trattamenti. Una possibile soluzione  per il risanamento delle acque reflue potrebbe essere l’applicazione della sonolisi, uno dei processi avanzati di ossidazione. La sonolisi è una scissione molecolare generata dall'energia prodotta dagli ultrasuoni, che hanno lo scopo di decontaminare le acque da inquinanti chimici tramite l'induzione di fenomeni cavitativi.In letteratura è dimostrata l'efficienza di questo trattamento terziario su singoli prodotti farmaceutici, ma mancano totalmente studi  riguardo l'efficacia su miscele.Al fine di ottenere i migliori risultati, si è studiato come il processo ad ultrasuoni agisca sulla degradazione di prodotti farmaceutici in singole soluzioni o in miscele addizionate nelle acque reflue urbane, al variare della densità di potenza, della concentrazione iniziale del substrato, del pH della soluzione iniziale e con l’insufflaggio d’aria.È stato scoperto che la conversione di prodotti farmaceutici è migliorata con la maggiore densità di potenza applicata, in condizioni acide e in presenza di aria disciolta.

In this letter we will discuss the reasons why there is no national medical guidelines in Libya, and we will provide suggestions on how to create local national clinical guidelines to improve the quality of healthcare in Libya.

Background Cutaneous polyarteritis nodosa (CPAN), a cutaneous vasculitis that affects small- and medium-sized arteries, is thought to be mediated by immune complexes. However, little is known about its etiology. Macrophages are important pathogenic factors in various vascular inflammatory diseases, including certain types of vasculitis. However, their role in CPAN remains unexplored. Objectives To describe the demographic, clinical, and laboratory findings and investigate the distribution of M1 and M2 macrophages in CPAN. Methods This was a cross-sectional study involving fourteen patients with CPAN and nine control participants. Medical records were reviewed to determine demographic and clinical data, and laboratory findings. Skin biopsies obtained during disease manifestations were evaluated immunohistochemically. M1 macrophages were identified using STAT1 expression, and M2 macrophages were identified using CD163, CD206, and CMAF expression. Results CPAN was predominant in women, and the mean age of patients was 39 years. The main dermatological lesions were ulcers, subcutaneous nodules, and livedo. Increased lipoprotein(a) levels (28%) and a positive tuberculin skin test in 40% of the tested patients were our main laboratory findings. Direct immunofluorescence was positive in 88.9% of the cases. Immunohistochemical analysis revealed an increased percentage of M2 macrophages in CPAN patients compared with that in the control group. Conclusions This is a novel study on macrophage polarization in CPAN, where the number of cells expressing CD163 and CMAF was found to be increased. M2 macrophage predominance suggests an important role for the innate immune system in the pathophysiology of CPAN and may provide insights for potential therapeutic targets.

ABSTRACT: Objective To investigate the Aneurysmal of the left sinus of Valsalva, and to improve the understanding of the disease and the level of diagnosis and treatment. Methods This article mainly reports a case of huge Aneurysmal of the left sinus of Valsalva patients treated with surgical treatment. Results After surgery, the prognosis of the case was good. Conclusion Aneurysmal of the left sinus of Valsalva has low incidence，which is rare in clinical with no clinical specific symptoms leading to difficulty in early detection. The appropriate surgical method should be considered to the patient condition, to prevent the tumor rupture and the death of patients.

Abstract Background Tumor immunity plays an important role in assessing the tumor progression. The purpose of this study was to investigate the prognostic value of combined systemic inflammation response index (SIRI) and platelet–lymphocyte ratio (PLR) for treatment of gastroesophageal junction cancer (AEG) and upper gastric cancer (UGC). Methods In this retrospective cohort study, patients from 2003 to 2014 were divided into training set (n=194) and validation set (n=177). The prognostic accuracy of each variable was compared using time-ependent ROC analysis. The scoring system was calculated by cut-off values of SIRI and PLR by ROC curve for survival in 5 years. Kaplan-Meier and Log-rank tests were used to analyze overall survival (OS). The chi-square test was used to analyze the association between clinical characteristics and the scoring system. Univariate and multivariate analyses based on the competitive risk regression model were used to analyze independent predictors of death due to AGC and UGC. The R software was used to construct the Nomogram model of risk assessment. Results Patients with SIRI–PLR=2 had worse survival time than those with 0 and 1 (P<0.001) and more suitable for postoperative adjuvant chemotherapy (P=0.003) and proximal gastrectomy (P=0.045). SIRI and PLR were independent predictors in training set (P=0.036, P=0.045), which could be combined with age and pTNM to construct Nomogram for predicting OS. Conclusions Preoperative SIRI–PLR score was an independent predictor for patients with AEG and UGC. The Nomogram model constructed by age, SIRI, PLR and pTNM can correctly predict the prognosis of patients.

Self-management is an essential component of chronic care. In this regard, the patient, even if well-informed about their disease or condition, needs to appreciate the necessity of physician’s supervision and shared decision-making.

Brazil is the largest country in South America with continental dimensions and significant regional differences. Recently, the country has faced a great challenge in establishing adequate strategies to mitigate the strong impact caused by the arrival of COVID-19 in the national territory. Since the first case diagnosed on February 26th, 2020, we have gone through a 18 week period that resulted in 58.300 deaths and more than 1.370.000 confirmed cases¹. Despite having a public and universal health system, most pediatric oncology centers are located in more urbanized regions, such as state capitals or economic centers. Few reports describe the impact of SARS-CoV-2 on the population of pediatric patients accompanied by cancer or undergoing hematopoietic stem cell transplantation (HSCT)2,3,4. Less frequent still are the descriptions of the situation of these children in low or middle income countries⁵. Faced with this new and unknown scenario, the present study aims to describe the clinical presentation and the evolution of children affected by COVID-19 undergoing treatment in units of oncology, hematology or HSCT. We are analyzing the interregional differences in the presentation, management and prognosis of these children, while drawing a national panorama that can be compared with other countries through a national and multicenter registry of children evaluated for SARS-CoV-2.Through dissemination by the Brazilian Society of Pediatric Oncology (SOBOPE), Brazilian Association of Hematology and Hemotherapy (ABHH) and Brazilian Society of Bone Marrow Transplantation (SBTMO). 36 centers across the country agreed to participate in this project (Figure 1). All regions of the country are included. The variables evaluated are clinical symptoms, diagnostic method, therapeutic measures and treatment location. In addition, the repercussions of infection on baseline treatment and overall prognosis are being assessed. Despite being in an initial phase, the database already counts with 64 registered cases.This joint work of the centers for pediatric oncology and bone marrow transplantation in our country is an advance that is allowing the development of one of the largest databases on the influence of COVID19 in the treatment of children in developing countries. Considering the small number of current literature on this subject, the heterogeneity of our population and regional differences, centralization of records is essential to better understand the extent and impact of this epidemic in our country, in addition to comparing the effect of local health strategies. It is important to highlight that the Sistema Único de Saúde (SUS), one of the largest and most complex public health systems in the world, guarantees universal health care and presents itself as a significant differential in combating the pandemic in Brazil through primary care, as well as medium and high complexity assistance.The development of this study will contribute to a better understanding of the clinical presentation, evolution and impact of that of COVID-19 in pediatric cancer patients or those undergoing HSCT in middle-income countries.

Background: Current cost-effectiveness evaluations of the house dust mite (HDM) allergen immunotherapy fail to account for its effect on the reduction of exacerbations and medications while considering potential differences across patient populations. We aimed to evaluate the cost-effectiveness of subcutaneous immunotherapy (SCIT) plus inhaled corticosteroids (ICS) vs ICS for pediatric and adult patients with allergic asthma (AA) and AA with Allergic rhinitis (AR) from the health care system perspective. Methods: A Markov model with a 3-month cycle length and a 10-year time horizon was developed. A hypothetical cohort of eight years old patients with controlled (or partially controlled) AA was the base case population. Health states were: treatment with GINA Step-3, Step-2, medication-free asthma, and all-cause death. Effectiveness was measured by the reduction in medication doses and exacerbations. Scenario analyses were conducted considering allergic AR as a comorbid condition and an 18-years old cohort at baseline with or without AR. Results: In the base case, the SCIT+ICS would avert 847 exacerbations per 1,000 patients treated and generate additional 0.37 quality-adjusted life years (QALYs) and $836 costs per patient (SCIT+ICS=6.79 QALYs at a cost of $1,438/patient, ICS=6.42 QALYs at a cost of $601/patient). An incremental cost-effectiveness ratio (ICER) of $2,238 per QALY that fall below the willingness to pay threshold was obtained. The SCIT+ICS was also cost-effective among sub-groups of interest: adults win AA (ICER=$2,227) and AA+AR patients (8-years old cohort=$1,628, 18-years old cohort=$1,617). Conclusion: the SCIT+ICS can be cost-effective for pediatric and adult patients with AA with or without AR

Background: Cancer predisposition syndromes (CPS) are underdiagnosed in the pediatric population, though the diagnosis of a CPS has important implications for the child and their family. CPS are often diagnosed by geneticists or oncologists with expertise in CPS following a malignancy. This requires a member of the care team, most commonly, the treating oncologist to suspect a CPS and refer the patient for assessment. Procedure: An online survey was distributed to members of the Children’s Oncology Group to elucidate current referral practices and barriers to referral for patients suspected to have a CPS. Results: Of the 189 respondents, 80.4% were pediatric oncologists and most (69%) used formal guidelines to aid in referral assessment. Most respondents indicated they would rarely refer patients with tumors highly associated with CPS. Participants were more likely to refer patients with malignancy and additional features of a CPS than for a specific type of cancer, despite the use of guidelines. Parent knowledge of family history was considered the most challenging barrier to obtaining a family history, though a thorough pedigree was not consistently elicited. Providers indicated the most significant barrier to referral was priority given the patient’s more immediate care needs. Conclusions: Provider education about CPS and creation of clear referral guidelines should increase appropriate referrals. Utilization of a genetic counselor within the pediatric oncology clinic may encourage CPS assessment and enable oncologists to focus on the patient’s immediate care needs.

The current search for host-susceptibility variants for COVID-19 contrasts with the fact that the study of the genetic architecture of Severe Acute Respiratory Syndrome (SARS) has been neglected. For human/SARS-CoV-2 interactome genes ACE2, TMPRSS2 and BSG, there is only one convincing evidence of association in Asians with influenza-induced SARS for TMPRSS2-rs2070788, tag-SNP of the eQTL rs383510. This case illustrates the importance of population genetics and of sequencing data in the design of genetic association studies in different human populations: the high linkage disequilibrium (LD) between rs2070788 and rs383510 is Asian-specific. Leveraging on a combination of genotyping and sequencing data for Native Americans (neglected in genetic studies), we show that while their frequencies of the Asian tag-SNP rs2070788 is, surprisingly, the highest worldwide, it is not in LD with the eQTL rs383510, that therefore, should be directly genotyped in genetic association studies of SARS in populations with Native American ancestry.

The origin and dynamics of the metabolic scaling is a fundamental problem in ecology and related sciences. The famous power law was queried by the notable variations of the power exponent and the non-log-linear curvature of metabolic scaling. Here, we proposed a novel enzyme-driven model of metabolic scaling based on the hypothesis that the key enzyme constrained the relative rate of both metabolism and growth based on the basic biochemical evidences. The predictions were tested by the broad range of compiled database from prokaryotes to higher animals. The results showed that: (1) both metabolism (Q) and body mass (m) were increased with the rate-limiting enzyme activity exponentially, (2) both natural logarithmic metabolism (lnQ) and body mass (lnm) were limiting resource dependent, and (3) lnQ was lnm dependent, that is the non-log-linear scaling, when Q and m had the different half-saturation constant of substrate response (KQ ≠ Km) and log-linear scaling when KQ = Km, which showed how and why the variation of scaling dynamics and the exponent. The results mean that the dynamics of metabolic scaling may be mainly originated from the enzymatic dynamics and the lnQ and lnm dependent model may be more general than the power law of metabolic scaling

Process analytical technology (PAT) has been defined by the Food and Drug Administration (FDA) as a system for designing, analyzing, and controlling manufacturing through timely measurements to ensure final product quality. Based on quality-by-design (QbD) principles, real-time or near-real-time data monitoring is essential for timely control of critical quality attributes (CQAs) to keep the process in a state of control. To facilitate next-generation continuous bioprocessing, deployment of PAT tools for real-time monitoring is integral for process understanding and control. Real-time monitoring and control of CQAs is essential to keep the process within the design space and align with the guiding principles of QbD. The contents of this manuscript are pertinent to the online/at-line monitoring of upstream titer and downstream product quality with timely process control. We demonstrated that a UPLC system interfaced with a process sample manager (UPLC-PSM) can be utilized to measure titer and CQAs directly from bioreactors and downstream unit operations, respectively. We established online titer measurements from fed-batch and perfusion-based alternating tangential flow (ATF) bioreactors as well as product quality assessments of downstream operations for real-time peak collection. This integrated, fully automated system for online data monitoring with feedback control is designed to achieve desired product quality.

Objective: Recommending using lymphopenia and neutrophil/lymphocyte ratio(NLR) as a severity marker rather than diagnostic marker for pregnant patients with COVID-19. Design: retrospective study. Setting :Birmingham city hospital, Birmingham, United Kingdom maternity unit admissions to delivery suite between 10 March 2020 and 31 May 2020. Population: We reviewed all patients who tested positive for COVID-19 and were pregnant. Methods: We looked at the white blood cell counts of all the patients and their outcomes. We specifically looked at lymphocyte count as well as neutrophil count and calculated the neutrophil lymphocyte ratio(NLR) for every case in our series. Main Outcome Measures: Only 15.3% of pregnant patients who tested positive for COVID-19 had lymphopenia and raised NLR in contrast with up to 90% in non-pregnant population. Results: Our results  indicate that out of 13 patients who tested positive, for COVID-19, only 2 915.3% had lymphopenia and raised NLR more than 8. Conclusions: There are very conflicting results for normal values of white blood cells and lymphocytes in pregnancy. In our study Lymphopenia and raised NLR do not seem to be common findings in confirmed pregnant cases of COVID-19 but can help determine morbidity as patients that had lymphopenia and raised NLR displayed severe symptoms, were more unwell and needed high dependency unit admission.

Enabled by rapid advances in sequencing technologies, population genetics currently experiences a second boom. Established approaches are being adapted to new marker systems, and new methods are developed that allow genome-wide estimates of the four major micro-evolutionary forces – mutation, gene flow, genetic drift and selection. Nevertheless, classic population genetic markers are still commonly used and a plethora of analysis methods and programs are available. With these diverse ranges of datasets and methods, various theoretical and statistical frameworks are employed to varying degrees of success in estimating similar evolutionary parameters making it difficult to get a concise overview across the available approaches. Presently, reviews on this topic generally focus on a particular class of methods to estimate one or two evolutionary parameters. Here, we provide a brief history of methods and a comprehensive list of available programs for estimating micro-evolutionary forces. We furthermore analysed their usage within the research community based on popularity (citation bias) and discuss the implications of this bias on the software community. We found that a few programs received the majority of citations, with program success being independent of both the parameters estimated and the computing platform. The only deviation from a model of exponential growth in the number of citations was found for the presence of a graphical user interface (GUI). Hence, developers should consider implementing GUIs in their programs in order to promote them.

Regular treatment of DKA patients includes rapid and large amount of fluids supply, which is not feasible in DKA patients associated with Uremia because of being urineless and prone to heart failure of these patinets. Our results indicated that continuous renal replacement therapy (CRRT) is a better alternative.

A novel process based on cyclohexene esterification–hydrogenation for the production of cyclohexanol, the key intermediate for the production of ε-caprolactam, was devised and validated for the first time. In this process, cyclohexene obtained from the partial hydrogenation of benzene is esterified with acetic acid to cyclohexyl acetate, followed by hydrogenation to cyclohexanol. The experimentally determined equilibrium conversion of cyclohexene for cyclohexene esterification at the stoichiometric ratio is always 68% in the temperature range of 333–373 K over the commercial Amberlyst 15 catalyst, which is substantially higher than that of cyclohexene hydration. The apparent activation energy (Ea) for the esterification of cyclohexene with acetic acid is 60.0 kJ mol–1, also lower than that of cyclohexene hydration. On the other hand, the hydrogenation of cyclohexyl acetate to cyclohexanol is not thermodynamically limited, and high conversion of 99.5% and high selectivity of 99.7% are obtained on the La-promoted Cu/ZnO/SiO2 catalyst.

In the one-step preparation of methylal from methanol, achieving high methylal yield is a huge challenge. To address this problem, in this study a new Mo:Fe(2)/CAR catalyst was designed, screened and optimised. The results showed that the optimised bifunctional catalyst had superior catalytic performance, and the yield of methylal could reach 81.33%, much higher than other research results of this process. Through the use of XPS, NH3-TPD and PY-FTIR it was found that the appearance of Mo5+ promoted the coordination of the two terminal oxygen with the Mo double bond in the Fe2(MoO4)3 octahedron, and that the increase in the weak acid strength of the catalyst and the coordination of suitable Brønsted acids (B acids) and Lewis acids (L acids) was the root cause of the catalytic activity. The apparent activation energy also further proved that Mo:Fe(2)/ HZSM-5(80-80) was highly suitable for the one-step production of methylal from methanol.

Ocean acidification is impacting marine life all over the world. Understanding how species are able to cope with the changes of seawater carbonate chemistry represents a challenging issue. We addressed this topic using underwater CO2 vents that naturally acidify some marine areas occurring off the island of Ischia. There, the brown alga Sargassum vulgare dominates the most acidified area, showing a pH value of 6.7, comparable to future, i.e. 2300, acidification scenarios. The novelty of the present study is the characterization of the S. vulgare proteome as response to ocean acidification. A total of 584 and 535 proteins were characterized in populations grown on current pH and acidified sites, respectively. 507 Proteins were significantly expressed in samples from both sites: 41 proteins were either up-regulated or exclusively present under acidified conditions, whereas 108 proteins were either down-regulated in the acidified site or present only under control conditions. Functionally, a decrease in proteins related to transcription and translation, and ER/Golgi trafficking and vesicular transport was observed under acidification. The up-regulated proteins are involved in the photosynthetic process and stress response. In addition, aminoacids metabolism was affected, which was reflected in their levels. Analyses of other metabolites revealed variations in the levels of some fatty acids and phenols. Overall, the results obtained by proteomics and metabolites analysis, integrated with previous transcriptomic, physiological and biochemical studies, have allowed to delineate the molecular strategies adopted by S. vulgare to grow in future acidified environments.
