AbstractSevere congenital neutropenia type 4 (SCN-4) is an autosomal recessive condition in which mutations in the G6PC3 gene encoding for the catalytic 3 subunit of glucose-6-phosphatase-β result in neutropenia, neutrophil dysfunction, and other syndromic features. We report a child with SCN-4 caused by compound heterozygous mutations in G6PC3, a previously identified missense mutation in exon 6 (c.758G&gt;A[p.R235H]), and a novel missense mutation in exon 2 (c.325G&gt;A[p.G109S]). The patient had recurrent bacterial infections, inflammatory bowel disease, neutropenia, and intermittent thrombocytopenia. Administration of granulocyte colony–stimulating factor (G-CSF) resolved the neutropenia and allowed for detailed evaluation of human neutrophil function. Random and directed migration by the patient’s neutrophils was severely diminished. Associated with this were defects in CD11b expression and F-actin assembly. Bactericidal activity at bacteria/neutrophil ratios &gt;1:1 was also diminished and was associated with attenuated ingestion. Superoxide anion generation was &lt;25% of control values, but phox proteins appeared quantitatively normal. Extensive metabolomics analysis at steady state and upon incubation with stable isotope–labeled tracers (U-13C-glucose, 13C,15N-glutamine, and U-13C-fructose) demonstrated dramatic impairments in early glycolysis (hexose phosphate levels), hexosemonophosphate shunt (required for the generation of the NADPH), and the total adenylate pool, which could explain the dramatic cell dysfunction displayed by the patient’s neutrophils. Preliminary experiments with fructose supplementation to bypass the enzyme block demonstrated that the metabolic profile could be reversed, but was not sustained long enough for functional improvement. In human deficiency of G6PC3, metabolic defects resulting from the enzyme deficiency account for diverse neutrophil functional defects and present a major risk of infection.

Published: December 2020

AbstractA revision of late Palaeozoic tectonics recorded in Tuscany, Calabria and Corsica is here presented. We propose that, in Tuscany, upper Carboniferous-Permian shallow-marine to continental sedimentary basins, characterized by unconformities and abrupt changes in sedimentary facies, coal-measures, red fanglomerate deposits and felsic magmatism, may be related with a transtensional setting where upper-crustal splay faults are linked with a mid-crustal shear zone. The remnants of the latter can be found in the deep-well logs of Pontremoli and Larderello-Travale in northern and southern Tuscany respectively. In Calabria (Sila, Serre and Aspromonte), a continuous pre-Mesozoic crustal section is exposed, where the lower-crustal portion mainly includes granulites and migmatitic paragneisses, together with subordinate marbles and metabasites. The mid-crustal section, up to 13 km-thick, includes granitoids, tonalitic to granitic in composition, emplaced between 306 and 295 Ma. They were progressively deformed during retrograde extensional shearing, with a final magmatic activity, between 295 ± 1 and 277 ± 1 Ma, when shallower dykes were emplaced in a transtensional regime. The section is completed by an upper crustal portion, mainly formed by a Palaeozoic sedimentary succession deformed as a low-grade fold and thrust belt, and locally overlaying medium-grade paragneiss units. As a whole, these features are reminiscent of the nappe zone domains of the Sardinia Variscan Orogen. In Corsica, besides the well-known effusive and intrusive Permian magmatism of the “Autochthonous” domain, the Alpine Santa Lucia Nappe exposes a kilometer-scale portion of the Permian lower to mid-crust, exhibiting many similarities to the Ivrea Zone. The distinct Mafic and Granitic complexes characterizing this crustal domain are juxtaposed through an oblique-slip shear zone named Santa Lucia Shear Zone. Structural and petrological data witness the interaction between magmatism, metamorphism and retrograde shearing during Permian, in a temperature range of c. 800–400 °C. We frame the outlined paleotectonic domains within a regional-scale, strain–partitioned, tectonic setting controlled by a first-order transcurrent/transtensional fault network that includes a westernmost fault (Santa Lucia Fault) and an easternmost one (East Tuscan Fault), with intervening crustal domains affected by extensional to transtensional deformation. As a whole, our revision allows new suggestions for a better understanding of the tectonic framework and evolution of the Central Mediterranean during the late Palaeozoic.

AbstractIn this research, we report the green, blue, and orange color emitting N-doped carbon dots (CDs), which are being synthesized from ascorbic acid and o-/m-/p-phenylenediamine (o-PDA, m-PDA, and p-PDA, respectively). The effects of the solvent polarity and solution pH on the PL emission properties of the as-synthesized CDs have been systematically investigated. It has been observed that the PL emission of the as-synthesized CDs decreases with the increase in solvent polarity due to the greater agglomeration. The surface charge of CDs also shows prominent effects on the pH-dependent PL emission properties.

Published: December 2020

AbstractCancer is one of the leading causes of morbidity and mortality in the globe. Microbiological infections account for up to 20% of the total global cancer burden. The human microbiota within each organ system is distinct, and their compositional variation and interactions with the human host have been known to attribute detrimental and beneficial effects on tumor progression. With the advent of next generation sequencing (NGS) technologies, data generated from NGS is being used for pathogen detection in cancer. Numerous bioinformatics computational frameworks have been developed to study viral information from host-sequencing data and can be adapted to bacterial studies. This review highlights existing popular computational frameworks that utilize NGS data as input to decipher microbial composition, which output can predict functional compositional differences with clinically relevant applicability in the development of treatment and prevention strategies.
A distance based multisample test for high-dimensional compositional data with applications to the human microbiome
Authors: Zhang Qingyang , Dao Thy 
Published: December 2020

AbstractBackgroundCompositional data refer to the data that lie on a simplex, which are common in many scientific domains such as genomics, geology and economics. As the components in a composition must sum to one, traditional tests based on unconstrained data become inappropriate, and new statistical methods are needed to analyze this special type of data.ResultsIn this paper, we consider a general problem of testing for the compositional difference between K populations. Motivated by microbiome and metagenomics studies, where the data are often over-dispersed and high-dimensional, we formulate a well-posed hypothesis from a Bayesian point of view and suggest a nonparametric test based on inter-point distance to evaluate statistical significance. Unlike most existing tests for compositional data, our method does not rely on any data transformation, sparsity assumption or regularity conditions on the covariance matrix, but directly analyzes the compositions. Simulated data and two real data sets on the human microbiome are used to illustrate the promise of our method.ConclusionsOur simulation studies and real data applications demonstrate that the proposed test is more sensitive to the compositional difference than the mean-based method, especially when the data are over-dispersed or zero-inflated. The proposed test is easy to implement and computationally efficient, facilitating its application to large-scale datasets.

Abstract
Background
Delirium is associated with high mortality after cardiac surgery. However, evidence on the epidemiology of delirium in patients with acute decompensated heart failure (ADHF) is limited. This study aimed to assess the incidence and prognostic impact of delirium in patients with ADHF.

Methods
This single-center prospective observational study enrolled 132 consecutive patients with ADHF. We utilized the Diagnostic and Statistical Manual of Mental Disorders, fifth edition and classified the patients into two groups according to the presence or absence of delirium. The primary endpoint was 90-day all-cause mortality. The prognostic impact and risk factors of delirium were evaluated using multivariable Cox and logistic regression analyses, respectively.

Results
The median patient age was 83 (interquartile range, 75–87) years. Approximately 51.5% were men. Delirium occurred in 36 (27.3%) patients, and hyperactive delirium was the most frequent type (86.1%). The 90-day all-cause mortality was higher in the patients with delirium than in those without (21.6% versus 3.9%, log-rank p = 0.002). Delirium was associated with higher mortality with an adjusted hazard ratio of 6.8 (95% confidence interval, 1.1–42.6, p = 0.042). The risk factors associated with delirium included advanced age, male sex, higher clinical frailty scale score, and dementia.

Conclusions
Delirium was associated with a higher 90-day all-cause mortality in the older adult patients with ADHF. Hyperactive delirium was the most common subtype.

Abstract
Background
Tunneled catheters can be used as an alternative vascular access in patients with limited health expectancy,vascular access problems and several comorbidities. We aimed to present a patient with venous stenosis related- reversible acute Budd-Chiari syndrome after catheter malposition.

Case presentation
After changing of tunneled catheter insertion, 36-year old man was admitted to our hospital with sudden onset of nausea, fever, chills and worsening general condition In computed tomography (CT) imaging, a hypodense thrombus was observed in which the distal end of the catheter is at the level of drainage of the hepatic veins in the inferior vena cava and that blocked hepatic vein drainage around the catheter. The catheter was removed and a new catheter was inserted in the same session. Because patient’s general condition was good and without fever, he was discharged with advices on the 9th day of hospitalization.

Conclusion
Although catheter malposition and thrombosis are not a common complication, clinicians should be alert of these complications.
Clinically relevant prognostic and predictive markers for immune-checkpoint-inhibitor (ICI) therapy in non-small cell lung cancer (NSCLC)
Authors: Brueckl Wolfgang M. , Ficker Joachim H. , Zeitler Gloria 
Published: December 2020

AbstractBackgroundImmune checkpoint inhibitors (ICI) either alone or in combination with chemotherapy have expanded our choice of agents for the palliative treatment of non-small cell lung cancer (NSCLC) patients. Unfortunately, not all patients will experience favorable response to treatment with ICI and may even suffer from severe side effects. Therefore, prognostic and predictive markers, beyond programmed death ligand 1 (PD-L1) expression status, are of utmost importance for decision making in the palliative treatment. This review focuses on clinical, laboratory and genetic markers, most of them easily to obtain in the daily clinical practice.ResultsRecently, a number of prognostic and predictive factors in association to palliative ICI therapy have been described in NSCLC. Besides biometric parameters and clinical characteristics of the tumor, there are useful markers from routine blood sampling as well as innovative soluble genetic markers which can be determined before and during ICI treatment. Additionally, the level of evidence is noted.ConclusionsThese factors can be helpful to predict patients’ outcome and tumor response to ICI. They should be implemented prospectively in ICI based clinical trials to develop reliable algorithms for palliative NSCLC treatment.

Authors: Kim Jinho , Whang Woong-Joo , Kim Hyun-Seung 
Published: December 2020

Abstract
Background
To analyze mean corneal powers and astigmatisms on anterior, posterior, and total cornea in patients with keratoconus as calculated according to various keratometric measurements using a Scheimpflug camera.

Methods
We examined the left eyes of 64 patients (41 males and 23 females; mean age 29.94 ± 6.63 years) with keratoconus. We measured simulated K (Sim-K), posterior K, true net power (TNP) and four types of total corneal refractive powers (TCRP). We then used the obtained values to analyze mean K, and corneal astigmatism. TCRP were measured at 2.0 ~ 5.0 mm.

Results
Mean corneal powers from Sim K, posterior K, and TNP were 49.12 ± 3.99, − 7.39 ± 0.79, and 47.78 ± 4.09 diopters, respectively. For TCRP centered on the pupil, mean K tended to decrease with measurement area (all p < 0.01). While, both mean K and astigmatism measured using TCRP centered on the apex decreased with measurement area (all p < 0.001). TCRP centered on the apex were greater than those centered on the pupil for mean K values calculated using TCRP (all p < 0.001). The proportion of WTR was greatest on the anterior and total cornea. As the measurement area moved to the periphery, the proportion of WTR increased.

Conclusions
Mean corneal powers and astigmatisms on total cornea with keratoconus change depending on calculation methods and measurement areas.
Mental health status of Chinese residents during the COVID-19 epidemic
Authors: Jiang Wen , Liu Xuerong , Zhang Jingxuan , Feng Zhengzhi 
Published: December 2020

Abstract
Background
To investigate the mental health status of Chinese residents during the epidemic of COVID-19, as well as to identify the positive and negative factors and regulatory effect of negative cognitive processing bias on mental health.

Methods
A total of 60,199 residents in China were surveyed via an internet-based survey containing a general questionnaire, such as the self-rating depression scale, the state anxiety inventory, and the negative cognitive processing bias questionnaire. An ordered multiple logistic regression analysis model was used to analyze the collected data.

Results
The survey revealed mild, moderate, and severe depressive symptoms in 62.65, 11.33, and 6.14% participants, respectively, and mild, moderate, and severe anxiety symptoms in 33.21, 41.27, and 22.99% participants, respectively. Multiple logistic regression analysis showed that factors, such as female gender, being older than 55 years, high school education level, medical staff, marital conflicts, negative attention bias, rumination, and death growth rate, positively affected depression and anxiety symptoms. The good family functionality, democratic working atmosphere, and a myriad of social activities negatively affected the level of depressive and anxiety symptoms.

Conclusion
Chinese residents exhibited a high prevalence of anxiety and depressive symptoms during the epidemic. Thus, psychological interventions should focus on the vulnerable groups, and cognitive training should focus on reducing the negative cognitive processing bias. This might be an effective way to alleviate the mental stress of the general public during the COVID-19 pandemic.
Walking the talk: evaluating the alignment between Australian governments’ stated principles for working in Aboriginal and Torres Strait Islander health contexts and health evaluation practice
Authors: Luke Joanne N. , Ferdinand Angeline S. , Paradies Yin , Chamravi Daniel , Kelaher Margaret 
Published: December 2020

Abstract
Background
Stated principles in government policy documents serve as a set of values outlining how governments intend to work. As such, health planning principles should be reflected in health policy across the cycle of planning, implementation and evaluation. Such principles should be reflected in the process of governments commissioning and funding evaluation, and in the work of those commissioned to do evaluation on behalf of governments.

Methods
We reviewed health planning policy documents to identify principles Australian State and Territory and National governments stated as being important to the work they do within Aboriginal and Torres Strait Islander health contexts. Evaluation tenders and reports relating to Aboriginal and Torres Strait Islander health policy, programs and service for the period 1-Jan-2007 to 1-Jan-2017 were retrieved and assessed as to whether they embedded principles governments state as important.

Results
In Aboriginal and Torres Strait Islander health planning policy contexts, Australian governments outline shared responsibility, cultural competence, engagement, partnership, capacity building, equity, a holistic concept of health, accountability, and evidence-based as fundamental principles that will underpin the work they will do.
In total, we identified 390 publicly advertised evaluation tenders, but were only able to retrieve 18 tenders and 97 reports. Despite strong rhetoric placing importance on the abovementioned principles, these were not consistently embedded in tenders released by government commissioners, nor in reports largely commissioned by governments. Principles most widely incorporated in documents were those corresponding to Closing the Gap - accountability, evidence-based and equity. Principles of holistic concept of health, capacity building, cultural competence and partnership do not appear well applied in evaluation practice.

Conclusion
Notwithstanding the tensions and criticism of current practice that sees dominant governments policing Aboriginal and Torres Strait Islander populations and defining what principles should inform health policy and evaluation practice, this paper reveals shortcomings in current evaluation practice. Firstly, this paper reveals a lack of transparency about current practice, with only 2% of tenders and 25% of reports in the public domain. Secondly, this paper reveals that governments do not ‘walk the talk’, particularly when it comes to principles relating to Aboriginal participation in health.
The impact of COVID-19 pandemic on dental practice in Iran: a questionnaire-based report
Authors: Ahmadi Hanie , Ebrahimi Alireza , Ghorbani Farhad 
Published: December 2020

AbstractBackgroundThe highly contagious nature of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), besides the fact that dental procedures commonly generate blood and saliva droplets that could lead to the contagion have resulted in the closure of many dental clinics. In the present study, we aimed to evaluate the impact of coronavirus disease 2019 (COVID-19) pandemic on dental practice by conducting an online questionnaire among the Iranian dental practitioners and finding their perspectives on the subject.MethodsThis report is based on a questionnaire that was conducted among Iranian dentists. The survey included questions that evaluate the dentists’ perceptions and attitudes toward the COVID-19 pandemic and its effect on their personal life, financial status, and the quality of dental services for patients.ResultsOverall, 240 dentists contributed to this study (214 general dentists and 26 specialists). The majority of the participants (n = 170, 70%) did not perform non-emergency procedures during the pandemic. The dental practitioners have suggested several strategies to decrease the risk of contagion, such as reducing treatment sessions (n = 90, 37%), strict triage of patients (n = 156, 64%), and using personal protective equipment (n = 108, 45%). However, most of the dentists (n = 210, 87%) had problems, providing personal protective equipment during the pandemic. Moreover, 97% (n = 234) of the participants reported that they encountered a decrease in their financial income since the eruption of the pandemic.ConclusionDental health care workers are at the highest risk of contracting COVID-19. Thus, dental practitioners ought to execute the standard protocols more cautiously during the pandemic. They could also lower their work hours and limit dental procedures to emergency treatments to reduce the risk of COVID-19 transmission. Besides, the public organizations should provide proper equipment for the dental practitioners to decrease the risk of contagion.

Tips for teaching procedural skills
Authors: Burgess Annette , van Diggele Christie , Roberts Chris , Mellis Craig 
Published: December 2020

AbstractThe teaching of procedural skills required for clinical practice remains an ongoing challenge in healthcare education. Health professionals must be competent to perform a wide range of clinical skills, and are also regularly required to teach these clinical skills to their peers, junior staff, and students. Teaching of procedural skills through the use of frameworks, observation and provision of feedback, with opportunities for repeated practice assists in the learners’ acquisition and retention of skills. With a focus on the teaching of non-complex skills, this paper explores how skills are learned; ways to improve skill performance; determining competency; and the provision of effective feedback.
