Authors: Baker Noah C. , Bowden Victor A. , DiGiorgio Anthony M. , Darbin Olivier E. , Menger Richard P. 
Published: April 2024

OBJECTIVE
Policy concern and debate surround the concept of overlapping spine surgery. Overlapping surgery specifically refers to nonessential portions of the case or noncutting time overlap. This differs from concurrent surgery, in which critical portions of the procedure overlap. Here the authors explore the barriers for safe and efficient overlapping surgery in academic spinal deformity practice.

METHODS
Over a 24-month period, cases of spinal deformity, degenerative cases, anterior cervical discectomy and fusions (ACDFs), and laminectomy were reviewed for duration in operating room (OR) prior to surgery, duration of cutting time, duration in OR after surgery, turnover duration, and time delay from initial start time. Standard degenerative cases were referenced as 1–2 ACDFs as well as 1- to 2-level laminectomy surgery. The blocks of time between two consecutive cutting periods were investigated to determine the feasibility of overlapping an additional surgery. Specifically, the authors compared the blocks of time that include the postsurgery period, the turnover period, and the presurgery period to cutting periods.

RESULTS
One hundred twenty-six complex spinal deformity procedures and 85 degenerative cases (including 49 ACDFs and 36 laminectomies) from one center and one neurosurgeon were reviewed. These procedures were performed between September 2019 and December 2021 with a 3-month gap in military deployment. On average, the procedure’s duration for cases of deformity was 236.5 minutes, for cases of ACDFs it was 84 minutes, and for cases of laminectomies it was 105.5 minutes. The block of noncutting time while the patient was in the OR showed no difference from the surgical cut time. The turnover time between cases was 52.35 minutes. Of 100 cases scheduled as the first case of the day, 94 had a delay to the OR averaging 18.2 minutes.

CONCLUSIONS
The data in this study indicate that estimates for pre- and postsurgical times alone are not sufficient to allow for overlapping surgery. The average cut-time duration of ACDF was 84 minutes; the average presurgical time for deformity was 68 minutes. This highlights the critical analysis for further examination of optimal scheduling, on-time first start, turnover periods, and the orchestration of all members of the providing team to optimize the cutting time for safe and consistent implementation of overlapping spine surgery.

Abstract Autonomous region is a term used to refer to a region that has the authority to regulate its own regional affairs. Based on Article 1 number 12 of Law 23/2014, an Autonomous Region is defined as a legal community unit that has certain regional boundaries and can be in the form of a province, city and district. Decentralization is a form of handing over government authority by the central government to autonomous regions so that they can regulate and manage their government. In 2022, Papua will experience regional expansion, resulting in four new provinces.Keywords: New Autonomous Region, Decentralization, PapuaAbstrak Daerah otonom adalah istilah yang digunakan dalam menyebut suatu daerah yang memiliki wewenang dalam mengatur urusan daerahnya sendiri. Berdasarkan Pasal 1 angka 12 UU 23/2014, Daerah Otonom didefinisikan sebagai kesatuan masyarakat hukum yang mempunyai batas daerah tertentu dan dapat berupa provinsi, kota, dan kabupaten. Desentralisasi adalah suatu bentuk penyerahan wewenang pemerintahan oleh pemerintah pusat kepada daerah otonom agar bisa mengatur dan mengurus pemerintahannya. Pada tahun 2022, Papua mengalami pemekaran daerah, dimana menghasilkan empat provinsi baru.Kata kunci : Daerah Otonomi Baru, Desentralisasi, Papua

Relevance. The work describes the prospect of using black soldier fly zoohumus as an organic fertilizer to activate the growth of microgreens of non-traditional legume species, including small-seeded ones, and the prospects of reducing the dose of mineral fertilizers.Methods. An experiment was carried out with a comparative study of changes in the morphometric and chemical parameters of plant growth at the full recommended dose of mineral fertilizers, and at 25% of their use, but with the addition of 1% liquid extract of zoohumus, also enriched with essential elements. The duration of the experiment was 21 days. The plants were grown in a closed grow tent, with intensive light culture and control of the internal microclimate of the working area.Results. Among the six studied non-traditional legume species grown for microgreens, the most responsive to combined treatment with an organomineral complex was Onobrychis viciifolia. Trifolium rubens showed the worst result in terms of biomass. Analysis of changes in the profile distribution of essential elements in the resulting green biomass, carried out using inductively coupled plasma atomic emission spectroscopy (ICP-AES), revealed iron and zinc ions as potential targets associated with yield shortfalls in juvenile shoots. Since in global food systems these microelements are the most common nutrients noted for the manifestation of “hidden hunger”, especially among children under 5 years of age and women of childbearing age, when creating a nutritional biocomposition based on black soldier fly zoohumus for growing non-traditional types of legumes, further the emphasis should be on them. No significant differences were found in the number of macroelements.Results. The results of the study confirmed the high efficiency of using humic fertilizers in conditions of low soil fertility and revealed the selective sensitivity of vegetable crops to humic preparations of various origins.

Relevance. The objectives of the work are to develop radio-hermetic installations and substantiate the effective design of the working chamber, which provides a comprehensive effect of electrophysical factors on non-food pulp raw materials to preserve feed value at reduced operating costs. Scientific tasks: 1) to develop installations with different designs of resonators; 2) to conduct a comparative analysis of the working chambers according to the main parameters; 3) to evaluate the technical and economic indicators of an effective installation in relation to the basic version.Methods. The effect of electrophysical factors on raw materials is realized in resonators with magnetrons and frequency generators of pulse-modeled high-frequency oscillations of 110 kHz, where a bactericidal flux lamp serves as a high-potential electrode.Results. Several continuous-flow radiohermetic installations with ultrahigh-frequency (microwave) power supply to non-standard resonators have been developed, inside which a complex effect of a high-intensity electric field, a bactericidal flow of UV rays and ozone is realized to reduce bacterial contamination of the product and neutralize odor during heat treatment of raw materials, the dimensions of which are consistent with the depth of penetration of the wave. Features of conical and biconic resonators − provide radio leakage in continuous operation by cutting off the tip at the level of the critical section, depending on the angle of inclination of the cone generator, and allow you to keep the standing wave inside the resonator. The combination of magnetron and cylindrical resonators increases the efficiency of the interaction of the electron flux with the microwave field, and an increase in the inductive volume, which is a “reservoir” of energy, increases the intrinsic quality of the resonator. A quasi-toroidal resonator, presented as a conical resonator in a toroidal resonator, having small overall dimensions and metal consumption, provides a traveling wave in the annular space, and a standing wave in the conical space. The high electric field strength in the capacitor part of the resonator and the corona discharge in the torus contribute to the disinfection of raw materials.

Relevance. At the same time, a prerequisite for a successful product on the market is its high organoleptic properties at a fairly low-price policy. As one of such approaches can be proposed the use of non-traditional plant raw ingredients (whole-milled flour from sprouted grain, β-glucan, pectin, etc.), which will allow to form high-quality food products of functional orientation.Methods. The objects of the study were defined as model mixtures of wheat flour baking flour of the highest grade and non-traditional raw materials, as well as samples of bakery products (sliced loaf) obtained according to the traditional (control) and experimental formulation. The rheological characteristics of the dough were determined by alveograph and farinograph. The quality of the finished bakery products was assessed on a 40-point scale, as well as the control of the specific volume and humidity of the products.Results. The studies showed that the introduction of β-glucan has a minimal effect on the elasticity of the dough, there is a decrease in the values of the quality index of farinograph on average by 17 - 22%. The dough elasticity decreases with the introduction of pectin more than 2 times, the values of quality indicator of farinograph increase, and the best result is characterized by the introduction of pectin in the amount of 2%, the maximum dough stability to kneading and minimum values of dough liquefaction degree are observed. Control and experimental samples of bakery products had high enough total values of organoleptic evaluation. The specific volume of experimental products increased by an average of 12% when beta-glucan was added in an amount of 0.1%, and by 8% when pectin was added in an amount of 4% relative to control samples. The obtained results confirmed the possibility and expediency of using non-traditional raw materials in the formulation of bakery products.

Relevance.The aim is evaluation in vitro antiproliferative activity of T. spiralis larvae extracts obtained from experimentally infected rats, depending on the duration of infection.Methods. The experiment was carried out on outbred male rats infected with T. spiralis larvae at the rate of 10 larvae per 1 g of body weight. The antiproliferative activity of larval extracts obtained 40 days, 3 and 12 months after infection was determined on tumor cells of the A549 line (human lung carcinoma) using an MTT test during cultivation for 24, 48 and 72 hours in concentrations from 32 to 1000 micrograms/ml. Antiproliferative activity was expressed as % inhibition and IC50.Results. There was direct dependence of Trichinella extract antiproliferative effects on time of cultivation with A549 cells and protein concentration in extracts. At all stages of invasion, the antiproliferative activity of the extract increased from 24 to 72 hours. at a protein concentration of 250 to 1000 mcg/ml. The extract antiproliferative activity expressed in tumor cell % inhibition and IC50 increased from day 40 to month 12. The most intense dynamics was observed between day 40 and month 3. The possible reason of enhancement in extract antiproliferative effect at months 3 and 12 is alteration in quantitative and qualitative composition of proteins comprised the extracts.

Relevance. It is known that the mineral composition of the feeds of the Republic of Bashkortostan used in animal diets, in terms of calcium, phosphorus, magnesium, copper, cobalt and sulfur, does not meet the needs of animals. The deficiency of minerals is especially high in growing young animals.In this regard, the development and scientific justification of the use of a complex mineral and vitamin feed additive (hereinafter CMVFA) in the diets of growing young sheep, which stimulate digestion and digestibility of nutrients in the diet, thereby increasing productivity, is of particular importance.Methods. To study the effectiveness of feeding KMVKD in the diets of the Romanov breed yarok on the indicators of body weight gain in peasant farming conditions, 4 groups of yarok were formed on the principle of pairs of analogues (10 heads each). Yarki of the control group received in addition to the main diet at the rate of 20 g of monocalcium phosphate and 15 g of premix per head (P81-1-89). The yarks of the experimental groups of KMVKD were introduced into the composition of crushed grain mixtures: made according to recipes No. 1 — for the first, No. 2 — for the second, No. 3 — for the third (35 g per head per day).Results. With a small difference in the intake of substances between the groups, the use of UMVD of 35 g per head per day had a significant impact on body weight gain. During the experiment period, the average daily weight gain in animals of the control group was 165 g, and in the experimental groups, respectively, 174.75 g, 183.52 g and 190.68 g, or more by 5.91%, 11.22% and 15.56% compared with the control. The level of profitability of production in the experimental groups increased by 10.60%, 16.03% and 20.54% compared with peers from the control group.

Relevance. In recent years, the increase in gross grain harvests of grain crops has occurred mainly due to increased adaptability and yield, in which a significant role was played by the introduction of new highyielding varieties into production.Methods. The object of the study is a new variety of spring barley Lyuboyar, entered in 2023 in the StateRegister of Breeding Achievements of the Russian Federation in the Northwestern, Central and VolgaVyatka regions. Yaromir and Reliable varieties were used as standards, and the most popular varieties Nur and Vladimir were used for comparative analysis. The studies were carried out by field and laboratory methods using appropriate techniques.Results. The yield of the new Luboyar variety, which amounted to 7.63 t/ha, consistently exceeds the yield of standard varieties (by 5.8–6.7%) and popular seeds on the market among Russian producers of Nur and Vladimir varieties (by 15.4–32.0%) for many years (2021–2023). The introduction of a new variety into production will allow you to get the highest conditional net income (29 016 rubles/ha) with a profitability level of 81.0% (23.2–43.9% higher compared to Nur and Vladimir varieties).

Relevance. The appearance of weeds in the fields of farms does not always imply their complete destruction, since from an economic point of view this may be ineffective. Therefore, in order to predict the effectiveness of crop contamination control in specific soil and climatic conditions, an urgent task is to develop and substantiate models of weed harmfulness and calculate economic thresholds for their harmfulness.Methods. The harmfulness of gray bristle (Setaria glauca (L.) Beauv) and green bristle (Setaria viridis (L.) Beauv) in the conditions of the Agro-Invest Plus LLC enterprise in the Karsunsky district of the Ulyanovsk region in 2021–2022 on the yield of Despina barley was studied. The economic harmfulness thresholds were calculated against the background of the use of herbicides Ovsyugen Super, CE — 0.5 l/ha; Axial 50, CE — 0.9 l/ha; Puma Super, EMV — 0.9 l/ha; Avantik Turbo, MD — 0.5 l/ha. The scheme of the experience included: Option 1 — without weeds (control), 2–6 options — with the number of weeds, respectively, 10 pcs/m2, 20 pcs/m2, 30 pcs/m2, 40 pcs/m2, 50 pcs/m2, option 7 — with natural blockage. The accounting area of the plot is 1 m2, the location is systematic with an offset, the repetition is 6 times.Results. Based on field experiments, predictive models have been developed to determine the harmfulness of weeds, which make it possible to establish economic thresholds for their harmfulness in the conditions of a particular farm. The harmfulness of the bristle according to the linear function was 0.106–0.147 c/ha, depending on the amount (pcs/m2) or 0.322–0.291 c/ha by weight (g/m2). According to prognostic models, the proportion (%) of changes in barley grain yield from contamination ranged from 79 to 85%. Studies have shown that chemical weeding is advisable in the presence of bristles in barley phytocenoses from 8 to 15 pcs/m2.

Published: April 2024

Relevance. In the structure of the acreage of the Northwestern region of the Russian Federation, a large proportion is occupied by perennial grasses, the herbage of which can potentially have severe weeds, and the harmfulness of weeds is high. Despite the current situation, the influence of weeds on the formation of an aboveground mass of grasses remains poorly understood.Methods. The purpose of the study is to assess the harmfulness of weed vegetation in the herbage of perennial grasses of the 1st and 2nd years of use in the north-west of the Russian Federation. The research was carried out in 2010–2018 in the fields of grain-grass-row crop rotation of the Menkovsky branch of the Agrophysical Research Institute located in the Leningrad region, in the structure of long-term experience with the application of mineral fertilizers and plant protection products.Results. Studies have shown that weeds cause significantly more harm (6.3 times) to perennial grasses of the 1st year of use than grasses of the 2nd year. Yield losses from the total value of the raw phytomass of weeds amounted to 15.75 c/ha (5.3%) and 2.51 c/ha (1%), including from 1 g/m2 at the time of mowing 0.150 c/ha (0.05%) and 0.07 c/ha (0.03%). The introduction of high doses of mineral fertilizers and the use of herbicides in the integrated crop protection system of grain-grass-row crop rotation led to a decrease in the harmfulness of weeds. In the perennial herbs of the 2nd year of use, the identified effects were significantly more pronounced than in the herbs of the 1st year. Under the influence of mineral fertilizers, the hazard coefficients decreased by 2.6 and 5.7 times, the protective measures systems — by 1.4 and 4.2 times, and the yield losses of green mass — by 2.6 and 10.7 times, 1.9 and 8.9 times, respectively, on grasses of the 1st and 2nd years of use.

Relevance. Organic production is focused on maximizing the use of natural resources. Particular importance is attached to natural nitrogen fixation. Nitrogen fixation provides agricultural systems with nitrogen fixed from the atmosphere and converted into forms accessible to plants. The microbial biological “Flavobacterin”, which exhibits nitrogen-fixing activity and also suppresses a wide range of phytopathogenic fungi and bacteria, was created at the All-Russian Institute of Agricultural Microbiology.Methods. Field studies of the “Flavobacterin” effects on potatoes were carried out from 2018 to 2022 in an organic crop rotation located at the Experimental Station of the Institute for Engineering and Environmental Problems in Agricultural Production Branch of FSAC VIM.Results. The soil of the experimental plot is soddy-podzolic, light loamy gleyic on residual carbonate moraine loam, characterized by a slightly acidic reaction and a high content of organic matter. Udacha variety potatoes were cultivated. The studies were carried out with organic fertilizer — BIAGUM compost, prepared from chicken manure by industrial method. Potato tubers were treated with a “Flavobacterin” when planting, and then on the leaves. Weather conditions in summer during the years of research differed significantly from each other. In all years of the study, with the exception of the dry year 2021, the application of “Flavobacterin” significantly increased potato productivity by an average of 4.4 t/ha, without compost. In the same years, the use of compost together with “Flavobacterin” increased potato productivity by an average of 2.6 t/ha compared to options where compost was used without biological.
