Authors: Belen Mustafa , Yanar Dürdane , Erdal Gülistan
Published: December 2020

Bu çalışmanın amacı, Sivas ilinin Merkez, Hafik, Yıldızeli ve Ulaş ilçelerinde buğday üretiminde; üreticilerin bitki koruma yönünden karşılaştıkları sorunları belirlemek ve üreticilerin bu konudaki bilgi düzeylerini ortaya koymaktır. Araştırmada, Sivas ilinin Merkez, Hafik, Yıldızeli ve Ulaş ilçelerinde 220 anket çalışması yapılmıştır. Çalışmanın yapıldığı alanda üreticilerin buğday üretiminde hastalık, zararlı ve yabancı ot bakımından sorunlar yaşadıkları belirlenmiştir. Üreticilerin neredeyse tamamı (%99,09) karşılaştıkları bitki koruma sorunlarını kimyasal mücadele uygulayarak çözmektedirler. Bu bağlamda üreticilerin en fazla kendi tecrübelerine (%84,09) göre tarımsal ilca uygulamaya karar vermektedirler. Bunu tarımsal ilca bayi tavsiyesi (%24,09), tarım uzmanının tavsiyesi (%17,27), komşu ve arkadaş tavsiyesi (%9,55) takip etmektedir. Üreticiler daha çok kendi eski tecrübelerine dayalı olarak ilaç uygulamaktadırlar. Bölgede son yıllarda üreticilerin zararlı, hastalık ve yabancı otlara karşı zirai mücadele ilaçları çok sık olarak kullandığı belirlenmiştir. Sınırlıda olsa aşırı dozda ilaç uygulaması söz konusu olup, bunun sonucunda çevre kirliliği ve insan sağlığına olumsuz etkilere neden olacağı kaçınılmazdır. Ayrıca üreticilerin yabancı ot mücadelesinde sadece geniş yapraklı yabancı otlara karşı ilaç kullandığı, dar yapraklı yabancı otlara karşı mücadelede yeterli bilgiye sahip olmadığı belirlenmiştir. Bu anket çalışması sonuçlarına göre bölgedeki buğday üreticilerine zirai mücadele konusun da eğitim verilmesi yararlı olacaktır.

Background. Children constitute a special population for off-label drug use (OLDU), yet limited drug-focused data exist regarding pediatric OLDU in clinical practice. This study aimed to investigate pediatric OLDU practice and compare it with pediatric drug utilization patterns of routine prescribing data.
Methods. This cross-sectional study examined all approved pediatric OLDU applications, compared with electronic prescription data on national Prescription Information System of Turkish Medicines and Medical Devices Agency in 2015. OLDU applications and prescriptions were analyzed for demographic characteristics, healthcare/socioeconomic indices as well as details of drugs and diagnoses.
Results. We found 7,896 OLDU applications and 7,029,512 prescriptions for the pediatric population in 2015. OLDU applications and prescriptions were mostly practiced for `2-11-year-old` children (52.7% vs. 63.4%, respectively; p < 0.01). OLDU applications and prescriptions were detected to have a positive correlation with socio-economic development index (r = 0.45, p < 0.0001 and r: 0.40, p = 0.0002; respectively) and the physician density (r = 0.66, p < 0.0001 and r: 0.43, p < 0.0001; respectively). In addition, OLDU was also positively correlated with the number of hospital beds per province (r = 0.39, p = 0.0003). Antineoplastic/immunomodulating agents were the most commonly applied drug category in OLDU (47.0%), compared with respiratory system drugs (36.6%) in routine prescribing. Eculizumab (6.5%), mycophenolate (5.6%), and canakinumab (4.4%) were the top drugs used as off-label. OLDU applications and routine prescription data revealed the most frequent diagnosis as `I27-other pulmonary heart diseases` (7.4%) and `J06-acute upper respiratory infections` (12.6%), respectively.
Conclusions. This is the first nationwide study to show indication- and drug-centered aspects of pediatric OLDU and prescribing practice. Though OLDU applications is overall consistent with routine clinical practice in terms of demographics and institutional capacity, substantial variations exist regarding main drug classes and diseases. Our findings are expected to shed light on interventions focused on improving `indicated` pediatric use of drugs currently applied as off-label.

One of the principal precepts of bioethics that all students in healthcare are taught in school which is a fundamental principle throughout of medicine, is referred as the Latin phrase “primum non nocere”. This means that, in regard to therapeutic strategies, it is first of all necessary not to harm the patient and for this reason, among the possible treatments, the one that has fewer contraindications should always be privileged. The current COVID-19 pandemic today counts more than 46 million cases and more than 1 million deaths worldwide. While the vast majority of the scientific community is working tirelessly on the development of vaccines and control of the application of the results produced by the use of drugs in hospitalized patients, few studies have dealt with issues related to the concepts of prophylaxis and treatment of the early phase of the disease. Prophylaxis includes strategies capable, on the one hand, of containing the spread of SARS-CoV-2, on the other hand, mitigating the development of the immune system imbalance caused in severe forms of Coronavirus disease. That is why we present the MATH + clinical guidelines, which were created thanks to an international alliance of doctors from around the world and a description of the clinical case when the MATH + clinical guidelines were used. Medicine is a direction of human activity, which in its charity knows no boundaries, age restrictions, emotions and prohibitions. The doctor everywhere rushes to the rescue neglecting personal. That is why we strive to help all health workers, who are at the Front Line in the fight for the lives of COVID-19 critical patients.
In situ grommet and fitness for flying
Authors: Raju AVK , Saxena S , Mohapatra SS
Published: December 2020

Introduction:

Current policies followed in the country do not permit aircrew to fly with in situ grommet. This paper discusses the aeromedical implications of in situ grommet, assessment of its flying fitness, and the factors which may be considered for possible reflighting of such cases.

Case Details:

A 19 year old civil pilot developed otitic barotrauma middle ear (right) which was managed with the placement of grommet in the tympanic membrane (TM). He was awarded fitness to fly on removal of grommet and after complete closure of the residual TM perforation. Another case, a 50 year old military pilot, a case of chronic suppurative otitis media (inactive) left ear, after uneventful recovery, was awarded flying medical category initially for in situ grommet and subsequently for single dry perforation TM in the left ear with an waiver from the competent medical authority.

Discussion:

Insertion of grommet, in cases with middle ear effusion and/or infection following Eustachian tube dysfunction, is a common practice to promote early recovery. However, as per the current policies in India, such aircrew are considered unfit for flying duty. Policies in other countries, military and civil, are mostly silent. This paper recommends the award of flying fitness for aircrew with in situ grommet provided that the clinical condition is stable, there are no complications and hearing is normal. This paper also discusses the award of flying fitness for aircrew with single and uncomplicated TM perforation with normal hearing for a specific type of aircraft.

Crossroads of Time: Now and Suddenly
Authors: Spector David M.
Published: December 2020

Considers prevailing interpretations of time, which apparently represent the impact of intellectualism in spite of being quite diverse. It is under its influence that time is replaced by an intellectual function. The universals of time forms are defined by the lubrication dogma (the past, the present, the future), which specify the nature of knowledge in the technology format. The mechanical universality deprives time of its emotional and aesthetic dimensions.

Zur Eigensinnigkeit des biographischen Erzählens in der (Flucht-)Migration – eine Fallanalyse
Authors: Chamakalayil Lalitha , Ivanova-Chessex Oxana , Leutwyler Bruno , Scharathow Wiebke
Published: December 2020

Das biographische Erzählen einer Migrationsgeschichte findet in machtvollen gesellschaftlichen Kontexten statt, die von rassialisierten Migrationsverhältnissen und neoliberalen Ordnungen strukturiert werden. Diese Kontexte reglementieren, was und in welcher Weise erzählbar wird. Zugleich sind Erzählende nicht durch die Bedingungen des Erzählens determiniert, sondern sie können ihre Erzählung eigensinnig strukturieren und sprachlich gestalten. Im vorliegenden Beitrag werden anhand einer Fallanalyse die Räume der Eigensinnigkeit des biographischen Erzählens rekonstruiert. Im Fokus steht die Auseinandersetzung mit der Frage, wie sich ein Erzählen über die eigene Fluchterfahrung im Kontext von migrationsgesellschaftlichen neoliberalen Ordnungen sowie in einer spezifisch situierten Interviewsituation gestaltet. Die Analyse folgt biographie- und subjektivierungstheoretischen Perspektiven.

Telah dilakukan penelitian tentang  profil tekanan bintang relativistik yang diturunkan kembali dengan menyelesaikan persamaan Einstein statik bersimetri bola untuk fluida ideal dengan densitas konstan dalam kondisi kesetimbangan hidrostatik. Penelitian ini menjelaskan profil tekanan dan batasan massa bintang berdasarkan model sederhana dalam konteks Teori Relativitas Umum. Hasil penelitian ini menunjukkan bahwa tekanan maksimum terjadi di pusat bintang dan akan menurun seiring bertambahnya jarak radial dari pusat bintang. Ditunjukkan pula bahwa dengan menerapkan syarat analitik pada persamaan profil tekanan akan menghasilkan batasan massa dari sebuah bintang relativistik. Untuk bintang bermassa M dan berjari-jari R batasan ini mensyaratkan bahwa  Apabila massa bintang melebihi batasan ini maka tekanan hidrostatik dari bintang tersebut tidak akan mampu mengimbangi tarikan gravitasionalnya sehingga runtuh menjadi objek kompak seperti bintang neutron dan lubang hitam.

Jelantah is the residual waste of cooking oil. The disposal of untreated waste directly into the environment has the potential to promote damage such as water channels clogging and water body pollution. Form of waste treatment such as biodegradation can be done using potential bacteria such as Pseudomonas spp. which has been known for being effectively in decomposing organic waste. This study aimed to observe the ability of Pseudomonas sp. BOT4 in degrading jelantah with different nitrogen sources i.e. NaNO3 and yeast extract. This study was carried out from August to October 2018. The used cooking oil samples were homemade with deep frying method and the isolate samples were collected from used cooking oil-contaminated sewer water. Split plot design was used with time of incubation as main plots and nitrogen sources as subplots. The parameters observed were cell density and degraded oil weight. The results obtained stated that nitrogen sources of NaNO3 and yeast extract given optimum effect on cell density of Pseudomonas sp. BOT4 on day three each with OD600 value of 1,361 and 2,300. Nevertheless both nitrogen sources did not really give real effect on final weight of degraded oil, each with weight of 1,28 g dan 1,09 g.

Published: December 2020

We present a novel algorithm to compute the distance between synthesis routes based on a tree edit distance calculation. Such distances can be used to cluster synthesis routes from a retrosynthesis prediction tool. We show that the clustering of routes from a retrosynthesis analysis is performed in less than ten seconds on average, and only constitutes seven percent of the total time (prediction + clustering). Furthermore, we are able to show that representative routes from each cluster can be used to reduce the set of predicted routes. Finally, we show with a number of examples that the algorithm gives intuitive clusters that can be easily rationalized. The algorithm is included in the latest version of the open-source AiZynthFinder software.

This review provides new literature data on the features of changes in the indicators of clinical and biochemical analysis of blood, as well as hemostatic and fib-rinolysis systems in patients with coronavirus infection COVID-19. It was shown that laboratory manifestations of COVID-19 have their own characteristics and are closely interrelated with the nature of the course of infection. In a clinical blood test, lymphopenia and thrombocytopenia are most common. Among the bio-chemical parameters of blood, an increase in the level of C-reactive protein and ferritin, as well as a decrease in the level of albumin, are more often detected. It should be noted that in 1/3 of severe patients with COVID-19 infection, the activity of liver enzymes, ALT and AST, increases. Among the indicators of hemostasis and fibrinolysis systems, an increase in the concentration of D-dimer in blood plasma is more often detected. The review also analyzes the possible causes of changes in some laboratory parameters with COVID-19.

Sensorineural hearing loss is one of the common diseases and it represents an urgent problem of otorhinolaryngology. The most complex and significant issues are acute and sudden sensorineural hearing loss. Every year, the number of patients suffering from this pathology is steadily growing. The increase in the number of cases of sensorineural hearing loss is associated with a number of socio-medical aspects of human life at the present stage – the growth of somatic and immune pathology, frequent stresses, high noise and vibration levels, regular use of headphones, environmental degradation and the influence of other adverse factors. The widespread use of audiometric research methods contributes to a more accurate diagnosis of impaired sound in patients of various age groups, which also affects the epidemiological data. In connection with the above, the study of modern treatment options for patients with sensorineural hearing loss is an urgent problem of clinical medicine.
