Post-Print: Interruptions to therapy sessions on acute psychiatric wards; how frequent are they, and who does the interrupting?
Authors: Jacobsen Pamela Charlotte
Published: November 2018

We carried out a study on offering people psychological therapy when they were admitted to hospital due to a mental health crisis. We know that psychiatric wards can sometimes be noisy and chaotic places, and so keeping the therapy room private, and therapy sessions uninterrupted can be challenging. As part of the study, we recorded how often therapy sessions on the ward got interrupted by other patients or ward staff, or when patients were called out of therapy sessions early to attend other meetings. We actually found that only a small number of therapy sessions got interrupted (just over 1 in 10; 13%) or ended early (less than 1 in 20; 3%). When sessions were interrupted, most of the time it was ward staff rather than other patients who were doing the interrupting. This information is helpful as it shows that most therapy sessions on wards can be completed as planned. It might be helpful to put in place a few practical steps to help ward staff be more aware when therapy sessions are being held (e.g. Do not Disturb signs on the door of the therapy room) and to remind them of the importance of not disturbing therapy sessions unless it is urgent.

Authors: White Alan Robert
Published: November 2018

Science skills are needed for innovation, economic prosperity and to solve global problems. Many students though have low self-efficacy and confidence levels when learning science subjects. Studies have shown that social media may have benefits when used in education. This study examines whether Facebook could be used as a learning tool to help increase student self-efficacy levels when learning science subjects. Data was collected from 166 non-science major students taking a physics course at a Thai university. The results of the study suggest Facebook when used as a learning tool may have potential for increasing student self-efficacy levels. Higher rates of Facebook participation were also found to result in higher self-efficacy levels.

Apoptosis as a mechanism of the albumin-induced kidney damage in childhood nephrotic syndrome
Authors: Burlaka Ie.A. , Bagdasarova I.V.
Published: November 2018

It was shown previously on in vivo studies that proteinuria-induced effects play a crucial role in renal damage in chronic kidney disease (CKD). However, an initial mechanism of irreversible kidney damage in pediatric diseases characterized by chronic proteinuria, i.e. nephrotic syndrome, remains to be unclear.

The aim of our work was to study the initial mechanism of kidney cells apoptosis development in nephrotic children.

Methods.An examination of renal biopsies of 53 patients (aged 10 to 15 years) with nephrotic syndrome hospitalized in Pediatric Nephrology unit of the Children Clinical Hospital №7 (Kyiv, Ukraine) done. In vitro studies of albumin toxicity performed on rat proximal tubular cells in primary culture (RPTC).

Results. Our study showed that albumin overload in nephrotic children leads to high levels of apoptosis. Its distribution and level varies regarding the level of focal segmental glomerulosclerosis (FSGS). The progression of sclerosis as a sign of irreversible kidney damage is accompanied by gradual increase in expression of proapoptotic factor Bax.

In vitro studies on rat proximal tubular cells in primary culture (RPTC) showed that excessive albumin uptake into rat primary renal cells causes an almost immediate mitochondrial accumulation of the apoptotic factor Bax. We hypothesize that this might be initial pathway leading to kidney cells apoptosis in childhood nephrotic syndrome.

Conclusions. We show thatoverexpression of apoptotic factor Bax has a place in children with nephrotic syndrome. Thus, chronic influence of albumin is a factor predisposing disturbances in system controlling apoptosis in this cohort of patients. Our data demonstrate that there is a dependence between the Bax overexpression level and the stage of CKD. We show the topologic difference between the Bax levels and FSGS degree. This is an indication thatdevelopment of glomerular and tubule-interstitial disorders under the influence of proteinuria occurs in specific range. In vitro data demonstrate that albumin overload causes mitochondrial Bax translocation that could be an initial factor in apoptotic pathway activation.

Authors: MacEachern Kristen N. , Kraguljac Alan P. , Mehta Sangeeta
Published: November 2018

Adults with acute leukemia (AL) are at high risk of malnutrition due to their disease and treatment side effects and may be admitted to the intensive care unit (ICU), further increasing the risk of malnutrition. Although ICU care includes some form of nutrition, patients typically receive less than prescribed energy and protein. Our objective was to characterize the nutrition care for critically ill patients with AL. We completed a retrospective review of adults with AL admitted to the Medical/Surgical ICU >24 hours. Descriptive statistics were performed on collected data including: demographics, APACHE II and Nutric scores, nutrition therapy, reasons for withholding nutrition, and mortality status at discharge. Data were collected on 154 AL patients with an average APACHE II score of 27 and Nutric score of 5.96. ICU mortality was 36%. Enteral nutrition (EN) was most commonly prescribed. Patients on EN received 55% of energy and 51% of protein prescribed. EN was commonly withheld for airway management and gastrointestinal impairment. Patients with AL received low amounts of energy and protein in the ICU and had a high Nutric score. Strategies and barriers to improve protein intake in this population are identified.

Authors: Fielding Allison , Taylor Lorian M. , Moriartey Stephanie , Stadynk Janet
Published: November 2018

Purpose: The study aim was to evaluate a patient experience survey, the Assessment of Registered Dietitian Care Survey (ARCS), that is aligned with a nutrition counselling approach (NCA) and evidence-based chronic disease care for use in outpatient registered dietitian (RD) practice.

Methods: Criterion and construct validity were examined using Pearson correlation coefficients and principal components analyses, respectively. Reliability was examined using Pearson correlations and Cronbach’s α. Acceptability was evaluated by survey response rate and readability. Kruskall–Wallis test was used to detect differences between RD scores.

Results: A total of 479 survey packages were returned (46% response rate). Criterion validity indices were high (r = 0.91 and 0.94, P < 0.001) between Patient Assessment of Chronic Illness Care (PACIC) and NCA subscales, respectively, and lower with overall patient satisfaction (r = 0.63–0.65, P < 0.001). Construct validity revealed 2 factors for PACIC and NCA subscales. There was high internal reliability for the PACIC, 5As, and NCA (Cronbach’s α > 0.7) and test–retest reliability showed an adequate consistency over time (r = 0.70, P < 0.05). The tool was able to detect differences in scores between RDs (P < 0.05).

Conclusions: More research is warranted to explore ceiling effects and sensitivity to intervention in similar practice settings. The NCA subscale has acceptable reliability and validity to measure patient experience of RD care.

Authors: da Silva Liz , Edmunds Christina , Grossman Talise , Kelly Lynn , Nattrass Cathryn , Saran Delara
Published: November 2018

Purpose: This study reports on dietitian use of the Nutrition Care Process Terminology (NCPT) diagnosis of malnutrition based on Subjective Global Assessment (SGA).

Methods: Nutrition assessment reports for adults in medical, surgical, and cardiac units in 13 Canadian hospitals were retrospectively examined for a 6-week period in 2014. Reports with a SGA and NCPT diagnosis were included regardless of why the patient was seen by the dietitian.

Results: Of the 932 nutrition assessment reports, 857 (92%) included an SGA. Based on SGA, the prevalence of mild to moderate malnutrition (SGA B) and severe malnutrition (SGA C) was 53.4% (n = 458) and 10.0% (n = 86), respectively. When categorized as severely malnourished, the most common NCPT diagnoses were “malnutrition” (n = 55, 72.4%), “inadequate oral intake” (n = 11, 14.5%), and “inadequate protein-energy intake” (n = 10,13.1%). Among those with SGA B and C, the assignment of the NCPT malnutrition diagnosis was 19.8% (n = 95).

Conclusions: Dietitians play a key role in the prevention, identification, and treatment of malnutrition in the hospitalized patient and are well positioned to take a leadership role in improving its documentation. Ongoing audits, staff support, and training regarding NCPT use may improve the application of the malnutrition diagnosis. Future research examining dietitian barriers to using the malnutrition diagnosis would be valuable.

Authors: Islamov D. F. , Sadretdinov A. A.
Published: November 2018

Common method of accounting for the deterioration of the filtration properties of the reservoir is the in-troduction of a dimensionless coefficient - skin factor. Traditionally, in order to determine the value of skin factor hydrodynamic research methods (well test) at non-stationary modes are applied (pressure recovery curve, level recovery curve) are used. In recent years, along with the pressure in well logging, bottom hole temperature dynamics is also recorded, that allows to use this data for obtaining the additional information about the reservoir and is a slower process, also about near wellbore zone. In this paper the possibility of de-termining the radius of the zone of permeability deterioration in the near wellbore zone from the non-stationary temperature measurements in well is studied; and also the sensitivity of the inverse problem solution to variation of simulation parameters.

Authors: Panikarovskii V. V. , Panikarovskii E. V.
Published: November 2018

At late stage of development of gas fields they need to solve the specific issues of increasing the production rate of wells and decreasing water cut. The available experience of development of gas and gas condensate fields proves, that the most effective method of removing of water, accumulating in wells, is an injection into the bottom hole zone of foam-forming compositions, based on surfactants. The most technological in the application was the use of solid and liquid surfactants. Installation in wells of lift columns of smaller diameter ensured the removal of liquid from the bottom hole of wells, but after few month of exploitation the conditions of removal of liquid from the bottom hole of wells deteriorate. The technologies of concentric lift systems and plunger-lift systems are used in small number of wells. The basic technology for removal of liquid from bottom hole of gas wells at present time is the technology of treatment of bottom hole of wells with solid surfactants.

Authors: Telitsyn V. L. , Novikov Yu. A.
Published: November 2018

In the article we consider the processes occurring at interaction of lakes and wetlands with surrounding geosystems. We pay attention to the formation of soils of heavy granulometric composition in the calcareous and lacustrine zones, which are subjected to salinization, solonetization and merging in the conditions of the forest-steppe and steppe. The research shows that over time, the lakes turn into swamps as the result of siltation and eutrophication, especially during intense technogenesis and agrogenesis. Our results confirm that peatlands are not saline, and they can be used for a variety of purposes. We suggest using environmentally compatible technologies for environmental engineering of wetlands and to return to them the original functions of freshwater lakes.

STRESS STATE COLUMNS OF TUBING STRING DURING OPERATION PULSED DOWNHOLE DEVICE
Authors: Khabibullin M. Ya. , Suleymanov R. I. , Sidorkin D. I. , Zainagalina L. Z.
Published: November 2018

When treating the bottomhole zone, the working fluid is supplied to the bottom unevenly due to the fact that the units are equipped with piston pumps. The changing amplitude of the liquid pressure is triggered in the pulsed downhole device. As a result, longitudinal oscillations are created in the tubing string. As the oscillations of the liquid propagate, their amplitude decreases. For these conditions, this is due to dissipative processes, which are called viscosity and thermal conductivity of the medium, the influence of the walls, and also scattering by inhomogeneities. We obtained expressions for determining the forced dynamic displacements and tensile stresses in each section of the tubing string, on which graphical dependences are plotted. As a result of the analysis of these curves, it was found that the usage of pulsed downhole device with a larger area of resistance to the flow of a liquid jet reduces the reliability of the tubing string, and it depends directly on both the design features of the device and the flow rate of fluid pumped into the formation. We also revealed that the reliability of the tubing string is increased by 1,8 times when using a packer for the equipment of the bottomhole of the treated well.
