Authors: Ismail Ismail , Anwar Rusli , Wartomo
Published: December 2021

This research is motivated by the importance of knowledge about alternative pest control that is safe but still supports the achievement of maximum oil palm production so that the balance of the oil palm plantation ecosystem can occur. The purpose of this study is to determine the technical cultivation and benefits of the Turnera subulata flower as a host plant for predators and parasitoids that function as biological agents for caterpillars and can be a reference for controlling caterpillar pests that are safe and still support the achievement of maximum oil palm production. The method used in this research is field observation and documentation from the company. The scope of this research covers the technical aspects of the biological control of caterpillars. This research data uses primary data and secondary data obtained from field observations and literature studies in the form of company reports in the form of percentages. The realization of Turnera subulata planting reached 21,659 m on CR road and 19,914 m on MR road. The planned planting of Turnera subulata is 57,200 m on the CR road and 45,823 m on the MR road. For the realization of the planting of Turnera subulata itself using seeds that are ready for planting. To obtain the seedling, the company conducts its nurseries. The seedling technique was done using the stem cutting technique. The stems for the cutting technique were taken from the Turnera subulata plant stems that have grown large. The type of stem taken is the old Turnera subulata plant stem. For seed care, the seeds are always watered every morning and evening like other flower plants. For the natural enemy insects, been proven that there are 6 natural enemy insects associated with Turnera subulata plants, 3 predators, and 3 parasitoids, each with a large enough number of insects. The types are Eocanthecona furcellata, Cosmolestes sp., Sycannus dichotomus, Spinaria spinator, Fornicia sp., and Chaetexorista javana. The development and the implementation of a control system are by optimizing the conservation and utilization of these biological control agents is a wise step to obtain an effective, efficient and environmentally friendly technique for controlling caterpillars. The presence of Turnera subulata plants can be used to suppress the development of pests in oil palm plantations by increasing the potential for natural enemies, both predators, and parasitoids. The diversity of wild plants with flowers can increase the variety of insects so that the balance of the ecosystem occurs.

Objective: To assess the frequency of cysts and tumors around impacted third molars. Study Design and Setting: Cross-sectional study was conducted at the OMFS department, Lahore Medical & Dental College, from August 2015 to January 2018. Methodology: A total of 2057 patients were operated for the removal of 2354 impacted third molars and analyzed for their associated pathological lesions(cysts/tumors). Patients were evaluated with thorough history, clinical and radiological examination. Panoramic and periapical radiographs were primarily used to assess the site of third molar impactions (maxilla/mandible) and their associated pathologies confirmed with histopathological examination. Data was analyzed using SPSS version 20. Results: The patients’ ages were between 17 to 62 years (Mean±SD, 28.12±8.585). There were n=709 (34.47%) females and n=1348 (65.53%) male with female to male ratio of 1.9:1. The mandibular to maxillary impacted third molars ratio was 1.66:1. An overall frequency of 1.36% for cysts and 0.72% for tumor associated with impacted third molars was demonstrated in the current study. The most frequently diagnosed cyst was dentigerous whereas ameloblastoma was the most commonly identified tumor. Conclusion: A relatively lower frequency (2.08%) of pathological lesions was found around third molars. The study reported a smaller number of pathological lesions affecting a significant minority of patients. It is recommended that a dentist/oral maxillofacial surgeon should be consulted at the earliest if any symptoms in the third molar region arise along with imaging of the area.

Authors: Bakhat Shaista , Taj Yasmeen , Hanif Faisal
Published: December 2021

Carbapenem resistance towards the gram negative microorganisms especially Pseudomonas aeruginosa is alarming and on-going public health problem all over the world. It may be intrinsic or acquired through transcription of genes among microorganisms. These genes are spreading rapidly and are responsible for serious out-breaks. So selection of antibiotics is limited to treat these resistant cases. Resistant genes are commonly extended in Europe, Asia (Turkey, India, China, Pakistan and so on) and South America. In Pakistan carbapenem resistance in Pseudomonas aeruginosa isolates is increasing among hospitalized patients. It shows a progressive trend in multidrug resistance (even towards last resort drug carbapenem). In this article, we offer an in-depth review of carbapenem resistant Pseudomonas aeruginosa. This will facilitate the readers to take effective measures in order to control infection and appropriate use of antibiotics.

Published: December 2021

Hypertension is an important worldwide public-health challenge due to its high prevalence and being a risk factor for cerebrovascular, cardiovascular, and chronic renal diseases. Despite these risk factors, blood pressure control among hypertensive patients is still poor.  The main objective was to assess dietary and lifestyle factors associated with uncontrolled blood pressure control among Ugandan hypertensive patients at Kiruddu hospital. Materials and methods: A cross-sectional study involving 271 adult hypertensive patients attending the outpatient hypertensive clinic was enrolled. Data were obtained on dietary, lifestyle factors (alcohol intake, smoking status, and level of physical activity), social demographics, Body Mass Index (BMI), comorbidities, and adherence to hypertensive medication. An average of the current and previous two Blood pressure readings was recorded. Factors associated with uncontrolled blood pressure were assessed using a multivariate logistic regression model. Results: The mean age of study participants was 57 ± 0.76 years, with female dominance (77.9%). Among the study participants, 121 (44.7%) had uncontrolled BP. Dietary factors that were associated with uncontrolled blood pressure with adjusted OR (95%CI) included consumption of raw salt: 4.18 (1.32-13.24) and inadequate fruit consumption: 2.18 (1.26-3.75) while clinical factors included being overweight: 2.51 (1.27-4.95) and poor adherence to antihypertensive medications prescribed: 1.82 (1.03-3.21). Conclusion: The proportion of hypertensive patients with uncontrolled Blood Pressure was high (44.7%). Consumption of raw salt, inadequate fruit consumption, being overweight and poor adherence to antihypertensive medication were significantly associated with uncontrolled BP. From these findings, factors that were associated with the control of blood pressure are modifiable.
Anesthesiologic management of elective endovascular stenting of coronary artery
Authors: Tsarkov A. V. , Levit A. L.
Published: December 2021

Introduction. Ischemic heart disease is the most common cause of death in the Russian Federation and in the world. One of the main methods of surgical treatment is endovascular stenting of the coronary arteries. Despite the minimally invasive method, there is a need to ensure sedation of the patient during the intervention. The main type of anesthetic aid for this procedure is monitored sedation.

The aim of the study was to conduct a comparative analysis of the two most frequently used regimens of monitored sedation for elective endovascular interventions in world practice.

Materials and methods. From January to July 2021, a prospective cohort study was conducted that included 70 patients. A comparison was made between the sedation group using phenazepam (n = 38) with the analgosedation group (n = 32) — a combination of sibazone and fentanyl. The comparison was made by the level of sedation (RASS scale), the severity of anginal pain at the stage of stenting of the coronary arteries according to the VAS; vital indicators of patients (sBP, dBP, avgBP, HR, SpO2).

Results. The use of a monitored sedation regimen (sibazone + fentanyl) leads to deeper sedation according to the RASS and a more significant decrease in heart rate in patients at the stage of coronary artery stenting compared with the use of benzodiazepine (phenazepam) alone. Despite this, the incidence of anginal pain during the intervention did not differ statistically significantly between the comparison groups.

Discussion. In this work, we compared two approaches to anesthetic protection when performing planned endovascular stenting of coronary arteries, which are most often used in foreign and domestic interventional practice.

Conclusions. The use of analgosedation (sibazone + fentanyl) for elective endovascular stenting of coronary arteries has no significant advantages over sedation with benzodiazepines (phenozepam) for these types of interventions. It becomes obvious that it is necessary to continue the search for more effective and safer schemes of anesthetic management during planned endovascular stenting of coronary arteries.

Published: December 2021

Introduction. The syndrome of posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological condition caused by vasogenic brain edema due to elevated blood pressure. The development of this syndrome is associated with the toxic effect of drugs in the treatment of oncological diseases. In most cases, timely diagnosis and therapy of PRES determine the complete reversibility of symptoms. However, a poor prognosis is possible with the development of severe disabling consequences or death. In practice, there are difficulties in the diagnosis of PRES due to the lack of specificity of clinical manifestations and awareness of many doctors about the existence of this syndrome.

The aim of the study was to present the clinical-radiological aspect of the syndrome of posterior reversible encephalopathy in children with oncological diseases.

Materials and methods. The analysis of 8 medical histories of children with oncological pathology complicated by the syndrome of posterior reversible encephalopathy was carried out.

Results. The study group was dominated by patients with hemato-oncological diseases. The development of PRES occurred during chemotherapy and in most cases was not associated with arterial hypertension. The clinical picture was dominated by such symptoms as impairment of consciousness, seizures and movement disorders in the form of paresis. When carrying out magnetic resonance imaging (MRI), the lesion of the white matter of the brain was determined, mainly in the projection of the parieto-occipital regions. During treatment, all patients showed reversibility of neurological symptoms with leveling of radiological signs.

Discussion. When analyzing the clinical and radiological characteristics of PRES in children, a comparison of the data with clinical observations presented in the literature was noted. The role of chemotherapy as a triggering factor in the development of posterior reversible encephalopathy syndrome has been determined.

Conclusion. The necessity of including the syndrome of posterior reversible encephalopathy in the list of differential diagnoses in patients receiving chemotherapy is shown.

Introduction. Acute respiratory distress syndrome (ARDS) and cardiovascular events, acute myocardial injury being the most frequent of the latter, are among the leading causes of death in COVID-19 patients. The lack of consensus on acute myocardial injury pathogenesis mechanisms, the patients management, treatment an rehabilitation logistics, the anticoagulant treatment in identified SARS-CoV-2 or suspected COVID-19 patients setting indicates the need to assess, analyze and summarize the available data on the issue.

Materials and methods. Scientific publications search was carried out in PubMed, Google Scholar databases for the period from December 2019 to September 2021.

Results and Discussion. Cardiospecific troponin I increase beyond reference limits is reported to occur in at least every tenth patient with identified SARS-CoV-2, the elevated troponin detection rate increasing among persons with moderate to severe course of the infection. The mechanisms of acute myocardial injury in patients with COVID-19 are poorly understood. By September 2021, there are several pathogenesis theories. A high frequency viral myocarditis direct cardiomyocytes damage is explained by the high SARS-CoV-2 affinity to ACE2 expressed in the myocardium. The cytokine storm related myocardial damage is reported a multiple organ failure consequence. Coagulopathy may also trigger myocardial microvessels damage. Up to every third death of SARS-CoV-2 infected persons is related to the acute myocardial injury. At the same time, due to the high incidence of the acute myocardial injury, it is rather difficult to assess the true incidence of acute myocardial infarction in patients with COVID-19. In the pandemic setting, the waiting time for medical care increases, the population, trying to reduce social contacts, is less likely to seek medical help. In this regard, in order to provide effective medical care to patients with acute myocardial infarction, it is necessary to develop algorithms for providing care adapted to the current epidemiological situation.

Conclusion. The treatment of patients with probable development of acute myocardial damage against the background of new coronavirus infection should be performed in accordance with the current clinical guidelines. Anticoagulant therapy should be administered in a prophylactic dose under control of hemostasis parameters and a wide range of biochemical parameters.

In 2016, 39% of adults aged 18 and up were overweight, with 13% being obese. Overweight and obesity kill more people than underweight in the majority of the world's population. In the year 2019, 38 million children under the age of 5 were overweight or obese. In 2016, over 340 million children and adolescents aged 5 to 19 years old were overweight or obese. Obesity can be avoided. Currently, India has over 135 million obese people. Until recently, the body mass index (BMI) was used to measure obesity. By 2020, there will be 158 million obese children around the world, rising to 206 million by 2025 and 254 million by 2030. In reality, India will have the most obese children after China, with 27,481,141 or 27 million, well ahead of the United States' 17 million.

This study evaluates a mindful eating-based program for people with self-reported binge eating problems. The study was initiated by a non-governmental eating disorder interest organization. Participants met once a week over eight weeks. The Eating Disorder Questionnaire (EDE-Q) and three subscales of the Self-Compassion Scale (SCS) were used to measure eating pathology, self-compassion and mindfulness before, after, and six-months after the program.

Results: Significant improvements in EDE-Q and SCS scores were found, and results remained stable at the six-month follow-up. The number of binge eating days decreased significantly during the study, both from before to after program participation, and from post-program participation to six-month follow-up.

Conclusion: Future studies investigating the current program are clearly needed. These preliminary results are nonetheless encouraging and illustrate that mindful eating-based interventions as an interesting treatment avenue for individuals with binge eating pathology, a group which currently has few treatment options available to them.

Keywords: binge eating disorder, binge eating, mindfulness, mindful eating, low-threshold services, obesity.
Reflections on constitutive relations for acoustic metamaterials
Authors: Willis John
Published: December 2021

I shall introduce a particular methodology for deriving effective constitutive relations for metamaterials including (because I was asked to do so) a brief account of how it evolved. It applies to composite materials (and metamaterials in particular) whose microstructure is random and is based on the calculation of ensemble averages. Periodic media are included as a special case, by regarding the exact location of a chosen point in any one cell as being distributed randomly over a cell fixed in space. Within that general framework, all definitions are exact. In practice, except in the case of periodic media, some approximation is required. The approximations developed here are derived systematically from a stochastic variational principle and can at least be regarded as “honest” even though not exact. Some general observations will be supported by examples which illustrate both the utility and the limitations of any formulation involving effective constitutive relations. In particular, except in the “homogenization” or “long-wavelength” limit, boundary layers present near any interface between random media, or between one random medium and one with uniform properties, seriously compromise the use of effective properties. The variational approach can, however, be applied directly to this configuration and has been employed to obtain one of only two solutions for reflection and transmission of acoustic waves at the boundary of a two-component random medium.
Parity-Time (PT) symmetry in chiral electromagnetic metamaterials
Authors: Kafesaki Maria
Published: December 2021

Combining chirality and Parity-Time-symmetry in a single metamaterial structure one can achieve a variety of novel propagation and scattering characteristics. These characteristics include mixed PT-related phases, multiple exceptional points, asymmetric reflection, asymmetric optical activity, and others. In the talk, besides discussing the possibility and conditions for the simultaneous coexistence of PT-symmetry and chirality, I will discuss all the above characteristics along with the potential to control them and exploit in a variety of applications related with electromagnetic wave polarization control.
Metamaterials, shear bands and invisibility
Authors: Bigoni Davide
Published: December 2021

Architected materials are preconized to yield extreme mechanical properties such as foldability, channeled response, and surface effects. These features are expected to lead to the production of artificial materials of unchallenged mechanical properties, in other words, metamaterials. Homogenization theory and Floquet-Bloch techniques will be applied to grids of elastic rods, subject to various conditions, including axial pre-stress, to demonstrate strain localization, wave channeling, total reflection, and negative refraction. Finally, invisibility through cloaking of voids in a flexurally vibrating plate will be presented.
Homogenization of resonant metafilms
Authors: Maurel Agnes , Pham Kim
Published: December 2021

In this talk, we will illustrate with three different examples the modeling of resonant metasurfaces using asymptotic homogenization techniques. We will first present the method on a periodic array of Helmholtz resonators (open cavities) in acoustics. In this case, the combination of bulk homogenization and interface homogenization allows to derive an approximated model in the time domain where the array of resonators is replaced by an anisotropic effective medium with effective jump conditions at boundaries. These conditions encapsulate all the evanescent contribution of the fields near the opening of the resonators and account for the transition between a quarter wavelength resonator to a Helmholtz resonator as the opening shrinks. In a second example we will focus on Mie resonance in elastodynamic for anti-plane shear waves. We will consider an array of sub-wavelength soft inclusions embedded in an elastic matrix. Due to the contrast of material properties between the constituents, the wavelength inside the soft inclusions become comparable to its size, hence leading to Mie resonances. We will show how asymptotic homogenization allows to capture the resonant behavior in an effective model consisting in frequency-dependent jump conditions across the array. Finally we will extend these results to a non-linear example in acoustic consisting in a screen of air bubbles inside water subjected to large pressure variations which is known to exhibit subwavelength Minnaert resonance. Homogenization theory applied to Navier-Stokes equations allows in this case to derive non-linear jump conditions where the behavior of the bubbles radii is governed by a non-linear equation of the Rayleigh-Plesset’s type.
Wave Control for Wireless Communications: From Time-Reversal to Reconfigurable Intelligent Metasurfaces
Authors: Fink Mathias
Published: December 2021

In this talk, I will show how the works performed at Langevin Institute have led 8 years ago to the seminal concept behind large reconfigurable intelligent surfaces (RIS) that is currently a topic of great interest in the wireless communication community and that is proposed as a new paradigm for the sixth generation (6G) of communication networks. Starting with the first demonstrations of ultrasonic time-reversal focusing in complex media, I will underline how these ideas were transposed later, for electromagnetic waves, into the concept of massive multi-user multiple-input multiple-output (MIMO) for the 5G communication networks. Then, I will explain how, working on the concept of wavefront shaping using spatial light modulators in optics, we propose an equivalent for the microwave domain, using tunable metasurfaces, a concept that would solve the drastic price problem of active techniques like time reversal MIMO. By smartly tuning the signal reflection of large metasurfaces, reconfigurable tunable metasurfaces are capable of dynamically altering wireless channels in disordered environments to enhance the communication performance. Using reconfigurable metasurfaces placed inside any complex environment, we tune the medium complexity to obtain the best communication performance. Compared to the well-known massive multiple-input multiple-output (MIMO) technique, RIS can provide excellent system performance without requiring power-hungry components such as power amplifiers.
Moth wings as metamaterial sound absorbers
Authors: Holderied Marc
Published: December 2021

Providing healthy living and working environments in our ever-noisier world necessitates increasing use of noise control technology. The rapidly expanding field of acoustic metamaterials has led to the emergence of ultrathin subwavelength sound absorbing methods, allowing sound insulation to be thinner and lighter than ever before. We will present our discovery of a natural acoustic metamaterial and show our ongoing work towards bioinspired metamaterial absorbers. Our bioinspiration arises from the 65-million-year acoustic arms race between echolocating bats and their moth prey, which has turned the wing scales of moths into an omnidirectional, ultrathin (1/100 λ) and broadband absorber of ultrasound (peak α = 0.71) that provides acoustic camouflage against bats. Our lithographically produced up-sized scale replicas absorb sound and can resonate at the most important frequencies for human communication. This research paves the way for bioinspired broadband sound absorbers that are thinner and lighter than existing solutions.
