Hypocalcaemia and hypophosphataemia following denosumab and IV ferric carboxymaltose in an older patient with normal renal function
Authors: Tai Rebecca , Mouchaileh Nadia , Ting Celia 
Published: February 2022

AbstractBackgroundSevere hypocalcaemia and hypophosphataemia following the co‐administration of denosumab and IV ferric carboxymaltose has previously been reported in the setting of chronic kidney disease and malignancy. Despite scarce evidence, there has been growing concern amongst clinicians of a possible drug interaction between denosumab and IV iron therapies. Although electrolyte abnormalities are well known side effects of these individual therapies, it is possible that co‐administration of the agents can exaggerate these effects and result in a potentially life‐threatening interaction.AimWe present a case of profound hypocalcaemia and hypophosphataemia following same day administration of denosumab and IV ferric carboxymaltose in a hospitalised older patient.Clinical detailsAn older female with normal renal function, serum calcium, phosphate and 25‐hydroxy‐vitamin D levels, and no history of malignancy was given denosumab 60 mg SC for secondary fracture prophylaxis following an acute osteoporotic fracture. On the same day, she received ferric carboxymaltose 1 g IV for treatment of iron‐deficiency anaemia.OutcomesFollowing a review of her pathology results during the inpatient hospital admission, profound hypocalcaemia and hypophosphataemia was identified 8 days after denosumab and ferric carboxymaltose administration. Despite supplementation, electrolyte abnormalities persisted for 12 days following administration.ConclusionAlthough the patient had no pre‐existing risk factors for developing electrolyte disturbance, profound hypocalcaemia and hypophosphatemia following denosumab and IV ferric carboxymaltose administration occurred, suggesting a possible interaction between the two therapies. Caution should be exercised by clinicians when these agents are co‐administered within a close timeframe.

ObjectivesWith the increase in dental implants for tooth loss, odontogenic sinusitis following maxillary dental implants is frequently encountered in otorhinolaryngology practice. The authors aimed to reveal the association between implant extrusion into maxillary sinus, along with implant‐related complications in patients diagnosed with implant‐related odontogenic sinusitis (IR‐ODS).Study DesignCase–control study.MethodsThis study enrolled 60 patients who received functional endoscopic sinus surgery due to IR‐ODS. The preoperative sinus computed tomography was retrospectively reviewed. Among the 120 maxillary sinuses of the 60 patients, 68 sides were diagnosed with IR‐ODS sides, whereas 27 sides showed no clinical or radiological evidence of this condition after the implant insertion and were defined as the control sides. Statistical analysis between these two groups was conducted, in addition to odds ratio (OR) calculations for associations with IR‐ODS.ResultsThe mean age of the IR‐ODS subjects was 59.5 ± 19.1, with a male to female ratio of 32/28 (53.3%/46.7%). Implants extruding by more than 4 mm into the maxillary sinus, peri‐implantitis, bone graft disruption–extrusion were associated with a significantly higher incidence in the IR‐ODS (p = 0.035, p = 0.003, p = 0.011, respectively). The IR‐ODS sides showed an adjusted‐OR (95% confidence interval) of 27.4 (2.7–276.5) for extrusion length >4 mm, 11.8 (3.0–46.5) for peri‐implantitis, and 34.1 (3.3–347.8) for bone graft disruption (p = 0.005, p < 0.001, and p = 0.003, respectively).ConclusionMaxillary dental implants extruding more than 4 mm into the maxillary sinus, peri‐implantitis, and disrupted–extruded bone grafts show significant association with IR‐ODS.Level of Evidence4 Laryngoscope, 133:237–243, 2023

Published: February 2022

AbstractIn this article, a broadband dual‐polarized filtering base‐station antenna is proposed. The structure of proposed antenna consists of a main radiation element, two parasitic rings, balun feeding line, and metal reflector. The parasitic ring embedded in the antenna radiating arm not only generates a high‐frequency radiation null, but also expands the antenna bandwidth. At the same time, a parasitic ring is loaded on the back of the substrate to generate a low‐frequency radiation null. These two parasitic rings make full use of the spatial position of the antenna and produce a better filtering effect. In order to verify the feasibility of the antenna, the designed antenna was processed and measured. In the end, the designed antenna achieves an impedance bandwidth of 48.3% (VSWR < 1.5, at 4.35 GHz), the measured average gain is 8.5 dBi. Out‐of‐band suppression at low frequencies (2–2.7 GHz) are greater than 27 dB, and out‐of‐band suppression at high frequencies (6.1–6.5 GHz) are greater than 17 dB. In addition, the antenna covers the 5G communication frequency band under Sub‐6G, which is suitable for 5G base‐station antennas.

Published: February 2022

AbstractTerahertz time‐domain spectroscopy (THz‐TDS) has become an emerging nondestructive detection technique due to the unique properties of THz waves; it offers safety, penetrability, and fingerprint identification, especially for commonly used non‐polar materials. Here, we measure the differences in THz spectra of four wood blocks (manglietia, amur linden, black walnut, and ebony) in the frequency range of 0.1–0.9 THz. In addition, we demonstrate the principal components analysis (PCA) applied in THz absorption spectra; the principal components extracted from original data by PCA can replace the original absorption coefficient data and can clearly distinguish the wood types. Results show that THz‐TDS combined with PCA can be used as an effective nondestructive identification method in the field of public security, food detection, and customs anti‐smuggling initiatives.

AbstractThe clinical use of surface imaging has increased dramatically, with demonstrated utility for initial patient positioning, real‐time motion monitoring, and beam gating in a variety of anatomical sites. The Therapy Physics Subcommittee and the Imaging for Treatment Verification Working Group of the American Association of Physicists in Medicine commissioned Task Group 302 to review the current clinical uses of surface imaging and emerging clinical applications. The specific charge of this task group was to provide technical guidelines for clinical indications of use for general positioning, breast deep‐inspiration breath hold treatment, and frameless stereotactic radiosurgery. Additionally, the task group was charged with providing commissioning and on‐going quality assurance (QA) requirements for surface‐guided radiation therapy (SGRT) as part of a comprehensive QA program including risk assessment. Workflow considerations for other anatomic sites and for computed tomography simulation, including motion management, are also discussed. Finally, developing clinical applications, such as stereotactic body radiotherapy (SBRT) or proton radiotherapy, are presented. The recommendations made in this report, which are summarized at the end of the report, are applicable to all video‐based SGRT systems available at the time of writing.

AbstractIntroductionKilovoltage (kV) X‐ray beams are an essential modality in radiotherapy. Solid state detectors are widely available in radiotherapy departments, but their use for kV dosimetry has been limited to date. This study aimed to evaluate the dosimetric performance of a range of solid state detectors for kV dosimetry.MethodPercentage depth doses (PDDs) and relative output factors (ROFs) were measured on an XStrahl 300 unit (XStrahl‐Ltd., UK) using 60, 100, 150, and 300 kVp X‐ray beams. The fields were defined by circular applicators with field sizes of 2, 5, 8, and 10 cm diameter and square applicators of field sizes 10 × 10 and 20 × 20 cm2. The following Physikalisch‐Technische Werkstätten (PTW) dosimeters were used for measurements: Advanced Markus, PinPoint 3D and Semiflex ionization chambers; photon, electron, and stereotactic radiosurgery (SRS) diodes plus the microDiamond detector. All PDDs were normalized at 5 mm depth, and ROFs were measured at 3 mm depth to avoid collisions with the end of the applicators. ROFs measured using chambers were corrected for polarity and ion‐recombination effects.Results and discussionPDD measurements for 60, 100, and 150 kVp beams exhibited good agreement between all diodes and the ionization chambers over the entire range of depths except in the first few millimeters near the surface. However, for the 300 kVp, all diode detectors exhibited an overresponding behavior compared to reference depth dose data measured with the Advanced Markus chamber. ROFs with the diodes were higher than the Advanced Markus chamber at low energy, and the magnitude of these differences is inversely proportional to the field sizes. The PTW P diode showed the highest variation of up to 15% in the output factor compared to the Advanced Markus chamber.ConclusionThis study evaluated the dosimetric performance of a range of solid state detectors in kV relative dosimetry. This study showed that diode detectors are a suitable replacement for ionization chambers for the PDD measurement of low energy kV beams (60–150 kVp) except for the PDD of 60 kVp with the smaller field sizes. However, an overresponding behavior of diode detectors at 300 kVp beams shows that diode detectors are not suitable for the PDD measurement of high energy kV beams. Generally, all solid state detectors overresponded to ROF measurements, indicating that it is not suitable for ROF measurements. In general, both shielded and unshielded diodes produced a similar dosimetric response, which demonstrates that the energy dependence of solid state detectors should be considered before they are used for any kV relative dosimetric measurements.

AbstractIntroduction/AimsThere is debate about whether and to what extent either respiratory or cardiac dysfunction occurs in patients with dysferlinopathy. This study aimed to establish definitively whether dysfunction in either system is part of the dysferlinopathy phenotype.MethodsAs part of the Jain Foundation's International Clinical Outcome Study (COS) for dysferlinopathy, objective measures of respiratory and cardiac function were collected twice, with a 3‐y interval between tests, in 188 genetically confirmed patients aged 11–86 y (53% female). Measures included forced vital capacity (FVC), electrocardiogram (ECG), and echocardiogram (echo).ResultsMean FVC was 90% predicted at baseline, decreasing to 88% at year 3. FVC was less than 80% predicted in 44 patients (24%) at baseline and 48 patients (30%) by year 3, including ambulant participants. ECGs showed P‐wave abnormalities indicative of delayed trans‐atrial conduction in 58% of patients at baseline, representing a risk for developing atrial flutter or fibrillation. The prevalence of impaired left ventricular function or hypertrophy was comparable to that in the general population.DiscussionThese results demonstrate clinically significant respiratory impairment and abnormal atrial conduction in some patients with dysferlinopathy. Therefore, we recommend that annual or biannual follow‐up should include FVC measurement, enquiry about arrhythmia symptoms and peripheral pulse palpation to assess cardiac rhythm. However, periodic specialist cardiac review is probably not warranted unless prompted by symptoms or abnormal pulse findings.

Published: February 2022

AbstractIn recent years, the field of flexible electronics has been thriving in academic achievements. Among them, the hydrogel‐based strain sensors possess some characteristic advantages in stretchability, flexibility, stickiness and regulable modulus of elasticity, thus they are more likely to attach to human skin and the surfaces of objects. Compared to traditional sensors, hydrogels can overcome shortcomings in toughness and elasticity. Therefore, hydrogels are suitable to serve as the core materials of wearable electronics. Hydrogel‐based strain sensors, as a typical kind of hydrogel flexible electronics, are in the categories of resistance sensors and capacitive sensors, which are primarily used for real‐time monitoring of human motions. This review mainly introduces the up‐to‐date relative literatures in the field of hydrogel‐based strain sensors.

AbstractRheumatoid arthritis (RA) is a chronic inflammatory disease that leads to cartilage damage with mostly accompanied by metabolic disorders. This study aimed to investigate the effects of curcumin supplementation on metabolic parameters (lipid profile and glycemic indices), inflammatory factors, visfatin levels, and obesity values in women with RA. This randomized, double‐blind, placebo‐controlled clinical trial was conducted on 48 women with RA. The patients were treated with curcumin (500 mg once a day) or placebo for 8 weeks. Fasting blood samples, anthropometric measurements, dietary intakes, and physical activity levels of subjects were collected at baseline and the end of the study. Curcumin supplementation significantly decreased homeostatic model assessment for insulin resistance (HOMA‐IR), erythrocyte sedimentation rate, serum levels of high‐sensitivity C‐reactive protein and triglycerides, weight, body mass index, and waist circumference of patients compared with the placebo at the end of the study (p < .05 for all). HOMA‐IR and triglyceride levels significantly increased within the placebo group. Changes in fasting blood sugar, insulin, other lipids profile, and visfatin levels were not significant in any of the groups (p > .05). These results support the consumption of curcumin, as a part of an integrated approach to modulate metabolic factors, inflammation, and adiposity in women with RA.

Authors: Mikriukova Mariia , Lahti Johanna , Kuusipalo Jurkka 
Published: February 2022

AbstractDue to the ability of oils to penetrate into the structure of polymers, it is possible to create slippery surfaces with low water droplet sliding angles based on polymer coatings. Polylactic acid, polybutylene succinate and low‐density polyethylene extrusion coatings were used as such surfaces in this study. The process of penetration of vegetable oils into the polymers was studied with the subsequent investigation of slippery behaviour of such system. Cottonseed oil and castor oil showed promising properties as lubricants. For oil infused polymer surfaces the water droplet sliding angles were significantly lower than for the untreated extrusion coating. The penetration of the permeant into the upper layers of the coating was confirmed by alteration of the static water contact angle, sliding angle and also by the cross section images. LDPE extrusion coating infused with castor oil showed the lowest water sliding angle − 8°. Biopolymers, being a main focus in this study, exhibited also promising results, PLA reached sliding angle of 14° with both olive and castor oil. Dependence of polymer permeability on various factors is rather complex and the wide range of oils used in this work helps to interpret the barrier performance of the studied materials. Degree of bond saturation, viscosity and polarity were found to influence mostly on the oil permeation through the studied polymers.

Published: February 2022

AbstractSuperhard materials are indispensable for use in cutting and polishing, as well as for nuclear reactor construction. As a candidate for hard material, ZrC has been extensively studied but not in its pressurized phase. Through evolutionary algorithm and density functional theory, we narrowed down the stoichiometry of Zr and C elements at various elevated pressures. The semimetal property of Zr4C4 continues to exist at high pressures but with lower electrical conductivity. Ionic and covalent bonding coexist around the pseudogap for high pressure phases. Both elastic constants and elastic moduli are found to increase steadily with surrounding pressure, connoting the superior mechanical and thermal characteristics of Zr4C4. This can be seen in the increased hardness values, higher melting temperatures, and better machinability indices for Zr4C4 as pressure rises. The predicted G/B and Poison's ratios have both agreed that Zr4C4 exhibits a transition from brittle to ductile behavior when the applied pressure goes above 85 GPa, displaying an overall improved mechanical performance.

AbstractWe introduce a new perfect sampling technique that can be applied to general Gibbs distributions and runs in linear time if the correlation decays faster than the neighborhood growth. In particular, in graphs with subexponential neighborhood growth like , our algorithm achieves linear running time as long as Gibbs sampling is rapidly mixing. As concrete applications, we obtain the currently best perfect samplers for colorings and for monomer‐dimer models in such graphs.

Published: February 2022

AbstractSoftware change‐proneness prediction can help reduce software maintenance costs. Thus, it has drawn the attention of many researchers. In this paper, we propose a CNN (convolutional neural network)‐based method for software change‐proneness prediction, aiming to utilize the powerful prediction ability to make score of the performance measure higher than other baseline methods. Moreover, to alleviate the effect of the class imbalance problem, resampling methods are employed with the CNN. To validate the performance of the proposed CNN‐based method, an empirical study was conducted. The experimental results show that the CNN‐based method together with the resampling method performs better than the baseline methods, and the scores of performance measure of CNN with the ROS (random oversampling) method are higher than other method, especially the important performance measure.
Band im Grünen – die Radwegbrücke Rosenau in Fulda
Authors: Hoier Andreas 
Published: February 2022

AbstractDer Neubau einer Radwegbrücke im Auenpark der Stadt Fulda ist das Herzstück eines neuen Geh‐ und Radwegkonzepts. Die Brücke schafft eine direkte Anbindung der umliegenden Stadtteile an die Innenstadt Fulda und bündelt die hessischen Fernradwege R1, R2 und R3. Eine in der direkten Nachbarschaft gelegene, vor 25 Jahren errichtete Holzbrücke kann nun zu einer reinen Gehwegbrücke umfunktioniert werden. Dies ermöglicht eine bessere Trennung der Verkehrsströme und erhöht die Verkehrssicherheit. Der Entwurf sah ein weit spannendes, elegant zurückgenommenes Band vor, das sich mit leichten Bögen in die Auenlandschaft eingliedert. Durch die doppelsymmetrische Linienführung der neuen Brücke, die geschwungenen Bögen der Zuwegung und die leicht verdrehte Ausrichtung relativ zu einer benachbarten Straßenbrücke entsteht eine harmonische Wegeführung, die sich fließend in die umgebende Auenlandschaft eingliedert. Entwurfsziele waren eine kurze und direkte Anbindung an das bestehende Radwegenetz, ein geringer Flächenverbrauch mit min. Eingriff in die Natur sowie die Errichtung eines ökologisch und ökonomisch nachhaltigen Bauwerks zur Stärkung umweltfreundlicher Mobilität.
