Published: February 2022

Background
Patients with sepsis and immobility in the intensive care unit are associated with muscle weakness, and early mobilisation can counteract it. However, during septic shock, mobilisation is often delayed due to the severity of the illness. Neuromuscular electrical stimulation (NMES) may be an alternative to mobilise these patients early. This study aims to identify whether NMES performed within the first 72 hours of septic shock diagnosis or later is safe from a metabolic perspective.

Methods
This is the analysis of two randomised controlled crossover studies. Patients with acute septic shock (within the first 72 hours of diagnosis) and sepsis and septic shock in the late phase (after 72 hours of diagnosis) were eligible. Patients were submitted in a random order to the intervention protocol (dorsal decubitus position with the lower limbs raised and NMES) and control (dorsal decubitus position with the lower limbs raised without NMES). The patients were allocated in group 1 (intervention and control) or group 2 (control and intervention) with a wash-out period of 4 to 6 hours. Metabolic variables were evaluated by indirect calorimetry.

Results
Sixteen patients were analysed in the acute septic shock study and 21 in the late sepsis/septic shock study. There were no significant differences between Oxygen Consumption (VO2) values in the acute phase of septic shock when the baseline period, intervention, and control protocols were compared (186.59 ± 46.10; 183.64 ± 41.39; 188.97 ± 44.88, p>0.05- expressed in mL/Kg/min). The same was observed when the VO2 values in the late phase were compared (224.22 ± 53.09; 226.20 ± 49.64; 226.79 ± 58.25, p>0.05). The other metabolic variables followed the same pattern, with no significant differences between the protocols. When metabolic variables were compared between acute to late phase, significant differences were observed (p<0.05).

Conclusions
As metabolic rates in septic shock patients had no increase during NMES, either in the first 72 hours of diagnosis or later, NMES can be considered safe from a metabolic viewpoint, even despite the higher metabolic demand in the acute phase of shock.

Treatment standards for direct oral anticoagulants in patients with acute ischemic stroke and non-valvular atrial fibrillation: A survey among German stroke units
Authors: Fastner Christian , Szabo Kristina , Samartzi Melina , Kruska Mathieu , Akin Ibrahim , Platten Michael , Baumann Stefan , Alonso Angelika 
Published: February 2022

Background
Acute ischemic stroke (AIS) in patients with non-valvular atrial fibrillation (AF) despite oral anticoagulation (OAC) is a complex and insufficiently investigated setting. Potential strategies range from maintaining the current OAC to changing the substance class. We have queried the specific treatment standards on German stroke units (SUs).

Methods
By means of a standardized online questionnaire via SurveyMonkey™ (San Mateo, CA, USA), all clinical heads of German SUs were asked about their treatment standards in the following clinical situations: first AIS of an OAC-naïve AF patient, AF patient with AIS despite administration of a vitamin K antagonist (VKA), AF patient with AIS despite administration of direct OAC (DOAC). In addition, the performance of specific coagulation tests in AF patients with AIS despite OAC was queried.

Results
160 (48%) clinical heads of German SU responded. Data from pivotal trials (84%), own experience with substances (71%), and side-effect profiles (66%) determine the initial DOAC prescription. In case of an AIS despite OAC, 83 and 18% would switch from VKA to DOAC under certain conditions and always, respectively. Half of respondents would switch from DOAC to VKA under certain conditions, while the other half would decline. 96% would switch to an alternative DOAC. The vast majority of those who made preconditions considered concomitant diseases (92, 90, and 81%, respectively). Few would consider infarct pattern (<35%). 61% perform initial coagulation tests (only one-third substance-specific assessments); however, the majority do not use these to make further decisions.

Conclusions
In the setting of an OAC-naïve AF patient with AIS, established pivotal data are most respected. In the unclear setting of an AIS despite OAC, most respondents consider concomitant diseases and give preference to switching to a (different) DOAC.
Assessing content and factors influencing responses to information requests in community pharmacies in Jordan: A simulated patients study
Authors: Hammad Eman A. , Al-Aqeel Sinaa , Elayah Eman , Jaber Deema 
Published: February 2022

Objectives
To assess the management of requests for information about a prescription only medicine (simvastatin for treatment of dyslipidemia) by pharmacy staff in community settings and explore the factors influencing the information content.

Methods
A cross sectional study conducted using the stimulated patient (SP) method between November 2018 and May 2019. The SP conveyed the request at the beginning of the encounter in a standardized way based on predetermined plots and was instructed to ask the pharmacy staff directly if information was not discussed spontaneously. After the visit, the SP provided written feedback including information about the scenario and a copy of individualized feedback. The study was reported according to the checklist for reporting research using simulated patient methodology (CRiSP). Factors influencing information content with or without information demand were investigated.

Results
A total of 55 visits were analyzed. The average content score for the information discussed spontaneously was 16.2% with the standard deviation (SD) equal to15.6. The score improved significantly after information was demanded by the SP; the average total information content score became 34.4% (SD = 16) with p < 0.001. The score of information discussed spontaneously was higher for male pharmacy staff, older age, more experience, and a Pharm D degree. When the SP prompted or demanded for information, older pharmacy staff with more experience and with a college degree scored higher. Independent pharmacies, longer visit durations, and less distraction were associated significantly with higher information scores Pharmacy staff aged 35–39 and those with 6–10 years of experience were significant contributors to spontaneous discussion of information with p values = 0.003 and 0.013, respectively. After the SP demanded information, pharmacy staff with less than 5 years of experience and greater confidence as well as longer visits were positively predicting higher information scores with p values of 0.049, 0.04, and 0.04, respectively.

Conclusions
Information provided by community pharmacists responding to information requests about prescription only medications was found to be suboptimal. Patient requests for information were found to be a positive driver for better information content. Further research of mixed methodologies is required to clarify the factors and motivators enabling information exchange in community settings and to outline true training needs.
Multi-dimensional Kronecker sequences with a small number of gap lengths
Authors: Weiß Christian 
Published: February 2022

Abstract
Recently, generalizations of the classical Three Gap Theorem to higher dimensions attracted a lot of attention. In particular, upper bounds for the number of nearest neighbor distances have been established for the Euclidean and the maximum metric. It was proved that a generic multi-dimensional Kronecker attains the maximal possible number of different gap lengths for every sub-exponential subsequence. We mirror this result in dimension d ∈ {2, 3} by constructing Kronecker sequences which have a surprisingly low number of different nearest neighbor distances for infinitely N ∈ ℕ. Our proof relies on simple arguments from the theory of continued fractions.
A study on serum homocysteine and oxidized LDL as markers of cardiovascular risk in patients with overt hypothyroidism
Authors: Kumar Singh Naveen , Suri Arpita , Kumari Mithlesh , Kaushik Priya 
Published: February 2022

AbstractObjectivesHypothyroidism is the most common endocrine disorder worldwide. Hypothyroisim increases cardiovascular risk, thus the study focuses on the assessment of cardiovascular risk factors such as serum Homocysteine, serum Oxidized LDL and Lipid profile and their correlation with TSH levels. Timely evaluation of these risk predictors would help in reducing cardiovascular disease morbidity and mortality in hypothyroidism.MethodsThis was a hospital based cross-sectional study consisting of Forty newly diagnosed patients with overt hypothyroidism in the age group of 20–60 years attending Medicine OPD were included as cases and Fifty healthy age and gender matched healthy controls participated as controls in the study. A written and informed consent to all the participants of both the groups was taken after explaining the purpose and details of the study. The Thyroid profile was assessed by CLIA-based MAGLUMI- 1000 analyzer and Serum total cholesterol, triglycerides and high-density lipoproteins were analyzed in Fully automated clinical chemistry analyzer EM-200 by using commercially available kits. LDL was calculated indirectly using Friedwalds equation. Commercially available ELISA-based kits were used for analysis of serum Homocysteine and serum oxidized-LDL.ResultsElevated levels of serum homocysteine (p<0.0001), Oxidized LDL (p<0.0001) were found in newly diagnosed overt hypothyroid patients as compared to controls whereas significant elevated levelsof TC, TG, LDL, and VLDL (p<0.0001) and decrease in HDLcholesterol (p<0.0001) were reported in newly diagnosed newly diagnosed overt hypothyroid patients.ConclusionsWe concluded that the association of hyperhomocysteinemia and lipid abnormalities occurring in hypothyroidism may represent a dynamic atherogenic state and thyroid hormone failed to completely normalize Hcy levels. Thus, elevated plasma homocysteine levels may be an independent risk factor for the accelerated atherosclerosis seen in hypothyroidism. In addition, we found that the circulating ox-LDL levels were elevated in untreated hypothyroidism and they tend to be higher in thyroid dysfunction.

Abstract

Objectives
Fructose 1,6 bisphosphatase (FBPase) deficiency is a rare autosomal recessively inherited metabolic disease. It is encoded by FBP1, and the enzyme catalyzes the hydrolysis of fructose-1,6-bisphosphate to fructose 6-phosphate. Patients with recurrent episodes of metabolic acidosis, hypoglycemia, hypertriglyceridemia, and hyperketonemia are present.

Methods
In this study, we describe the clinical, biochemical, and molecular genetic features of six unrelated Turkish patients from six different families who were genetically diagnosed with FBPase deficiency in our clinic between 2008 and 2020. Their clinical and laboratory data were collected retrospectively. Next-generation sequencing (NGS) was performed for the molecular genetic analysis.

Results
All patients were hospitalized with recurrent hypoglycemia and metabolic acidosis episodes. Three out of six patients were presented in the neonatal period. The mean age at diagnosis was 26 months. NGS revealed a known homozygous gross deletion including exon 2 in three patients (50%), a known homozygous c.910_911dupTT pathogenic variant in one patient (16%), a novel homozygous c.651_653delCAGinsTAA likely pathogenic variant, and another novel homozygous c.705+5G>A splice site variant. Leukocyte FBPase analysis detected no enzyme activity in the patient with homozygous c.705+5G>A splice site variant.

Conclusions
We identified two novel mutations in this study. One of them is a splice site mutation which is five bases downstream of the exon, and the other one is an indel mutation. Both of the splice site and indel mutations are exceedingly rare in FBP1, and to the best of our knowledge, there are second splice site and indel variants reported in the literature. Exon 2 deletion is the most common mutation consistent with the previous reports in Turkish patients. FBPase is a frequent cause of hypoglycemia and metabolic acidosis, and the widespread use of molecular genetic analysis would contribute to the enlightenment of advanced genetic factors and possible genotype/phenotype correlation.

Preparation and morphological studies of tin sulfide nanoparticles and use as efficient photocatalysts for the degradation of rhodamine B and phenol
Authors: Oluwalana Abimbola E. , Ajibade Peter A. 
Published: February 2022

Abstract
Tin sulfide nanoparticles were prepared from tin(ii) dithiocarbamate complexes: bis(benzylmethyl dithiocarbamate)tin(ii) (SnS1), bis(dibenzyl dithiocarbamato)tin(ii) (SnS2), and bis(imidazolyldithiocarbamato)tin(ii) (SnS3) single-source precursors. Powder X-ray diffraction patterns of the as-prepared tin sulfide nanoparticles confirmed orthorhombic crystalline phase irrespective of the tin(ii) dithiocarbamate precursors used to prepare the tin sulfide nanoparticles. Transmission electron microscopic images showed SnS nanoparticles with average particle size of 1.35 ± 0.04 nm for SnS1, 2.63 ± 0.65 nm for SnS2, and 1.55 ± 0.15 nm for SnS3. The energy bandgap of the SnS nanoparticles obtained from Tauc plots are in the range 3.80–4.37 eV. The as-prepared SnS nanoparticles were used as photocatalysts for the degradation of rhodamine B with efficiency of 90.97, 61.53, and 80.26% for SnS1, SnS2, and SnS3, respectively, while for phenol degradation efficiency was 96.45, 75.13, and 90.69% after 180 min. The results indicate that the as-prepared SnS nanoparticle are efficient photocatalyst for rhodamine B and phenol degradation. The photocatalytic degradation of rhodamine B and phenol follows pseudo-first-order reaction kinetics model from which the photodegradation rate could be obtained. Scavenger studies show that electrons (e−), hydroxy radicals (˙OH), and holes (h+) play significant role in the photodegradation of rhodamine B and phenol by the SnS nanoparticles. Recyclability studies show the SnS photocatalyst could be reused for four cycles without losing its photodegradation ability.
Referential accessibility as an index of the discourse functions of predicative and specificational clauses
Authors: van Praet Wout 
Published: February 2022

Abstract
This paper studies referential accessibility marking in predicative and specificational clauses, in particular the ones in which the roles of ‘description’ and ‘variable’ are realised by an indefinite NP (e.g. He is a baker
vs.
One of his talents is pastry). While the indefinite NP in the two clause types has been studied in detail, little is known about how the other two roles – of ‘describee’ and ‘value’ – are typically realised. This study, therefore, examines the choice of referring expressions for the items filling these roles, as an index of their retrievability and degree of accessibility. The analysis is based on 750 corpus examples from spoken and written British English. Moreover, since specificational clauses allow for the value to be either complement or subject, this study also provides insight into what may motivate the choice for one pattern or the other. Significant differences were found between describees and values, as well as between value-subjects and value-complements. These findings are interpreted as indicative of different discourse functions of the three constructions. While predicative clauses typically elaborate familiar information, specificational clauses serve a broader discourse-organising function: starting a new discourse-topic, pivoting from one topic to another, or summarising prior propositions as concluding a topic.

Published: February 2022

Consensus protocol organizes gastric emptying scintigraphy (GES). There is low adherence to the protocol, and its applicability is reduced due to poor connection between retention and functional disorders. To optimize the consensus protocol, we added a dynamic acquisition and quantification of distinct parameters for healthy and dyspeptic subjects. Fourteen patients with functional dyspepsia (FD) and 20 healthy volunteers were undergone GES. The dynamic acquisition was added to the activity versus time curve composed of 4-time points (0, 60, 120, and 240 min) preconized. A dynamic set of 3060 images (1 Hz) were acquired between immediate and 60 min static images. Regions of interest were drawn to divide the stomach internally, and two gastric segmentations (similar areas and incisura) were adopted for all quantification of global GE and contractile parameters. Gastric retention at 4-time points preconized was not enough to identify differences between FD and healthy volunteers (R² = 0.99; p ˂ 0.0009). Retention percentage of test meal in the proximal stomach employing segmentation, T1/2, MGET and lag phase analysis were higher in dyspeptic compared to healthy volunteers. Impaired intragastric meal distribution was observed in FD by similar areas (p < 0.02) and incisura (p < 0.001). Reduction in the amplitude of contraction from the proximal region (p ˂ 0.015 and p ˂ 0.003) was observed in FD segmentation by similar areas and incisura, respectively. Impaired proximal stomach was observed in functional dyspepsia due to the insertion of dynamic acquisition proposed by consensus. Our approach can strengthen the consensus protocol and makes it capable of recognize and classify some diseases.

Published: February 2022

The aim of this study was to evaluate the feasibility of using acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) 3D printing filaments as materials for mammography phantom construction, comparing their attenuation properties at two different set-ups: at a Calibration Laboratory and directly to a mammography unit. The attenuation of 3D printed test phantoms of two types of common 3D printing Fused Filament Fabrication (FFF) filaments (ABS and PLA) were characterized in comparison with polymethylmethacrylate (PMMA). The measurements were carried out with standard IEC 61267 X-rays, using RQR 2-M and RQR 4-M beam qualities at the Instruments Calibration Laboratory, and then applied to a mammography unit, with measurements with 28 kVp and 35 kVp. Attenuation characteristics evaluated indicates the suitable equivalence of PLA to PMMA for 3D printing breast tissue equivalent complex phantoms. The plastic materials used in this study suggest that the FFF technique may be suitable for mammography phantom development.

Published: February 2022

The use of 3D printing technologies is growing widely, including the possibility of design phantoms for imaging and dosimetry. For that, high attenuation tissues such as cortical bone, dentin and enamel need to be mimicked to accurately produce 3D printed phantoms, especially for Fused Filament Fabrication (FFF) printing technology. A Radiopaque FFF filament commercially available had been hard to be found; and this study aims to report, step-by-step, the development of a radiopaque FFF filament. A combination of radiopaque substances (Barium Sulfate - BaSO4 and Calcium Carbonate - CaCO3) was selected using the National Institute of Standards and Technology (NIST) XCOM tool theoretical data and added as filler in an Acrylonitrile Butadiene Styrene (ABS) matrix. The filament was homogenized and gone under first characterizations by analyzing its density, Scanning Electron Microscopy (SEM), Computed Tomography (CT) and micro-CT (µCT) scans. Three filaments were produced with different Hounsfield Units (HU) equivalences: XCT-A (1607HU), XCT-B (1965HU) and XCT-C (2624HU) with respective densities of 1.166(6) g/cm³, 1.211(2) g/cm³ and 1.271(3) g/cm³. With these values, high attenuation tissues, such as bones, dentine and enamel, can now be mimicked with FFF 3D printing technology, at a low cost of production.

Published: February 2022

BACKGROUND
Surgical correction remains the most effective treatment of patients with severe neuromuscular scoliosis (NMS). However, postoperative inpatient clinical care after spinal surgery for NMS patients is highly complex and variable, depending on the provider and/or institution. Our project used a quality improvement methodology to implement a standardized clinical care pathway for NMS patients during their primary spinal surgery, with the global aim of decreasing postoperative hospitalized length of stay (LOS).

METHODS
A multidisciplinary team developed a postoperative pathway for nonambulatory patients with NMS after their primary, nonstaged corrective spinal surgery. The outcome measure was mean LOS, and the process measure was percentage compliance with the newly implemented NMS pathway. The team used statistical process control charts and measures were evaluated over 3 phases to assess the impact of the interventions over time: pretesting, testing, and sustain.

RESULTS
The mean LOS decreased from 8.0 to 5.3 days; a statistically significant change based on statistical process control chart rules. Percentage compliance with the NMS pathway improved during the testing and sustain phases, compared with the pretesting phase. LOS variability decreased from pretesting to the combined testing and sustain phases.

CONCLUSIONS
Using quality improvement methodology, we successfully standardized major components of clinical care for patients with NMS after spinal corrective surgery. Through enhanced care consistency, the mean postoperative LOS decreased by nearly 3 days and decreased LOS variability. Robust multidisciplinary involvement with key stakeholders ensured sustainability of these improvements.
