Authors: Dvinskikh S A , Larchenko O V 
Published: September 2019

AbstractThe article gives a hydrographic description of the pond, the results of bathymetric work in the summer of 2017. Examines the factors that shape the environment. A detailed description of the chemical composition of water is given. The degree of pollution of a reservoir on its separate sites is revealed. It is shown that bottom sediments play an important role in the formation of the Motovilikha pond ecosystem. They accumulate pollutants and trace elements, so they can be considered as a marker of water quality and at the same time a source of secondary pollution.
The plankton community structure in the zones with different thermal condition (Kharanorskaya TPP cooling pond, Transbaikalia)
Authors: Afonina Yu E , Tashlykova N A 
Published: September 2019

Abstract
The research results of plankton biocenoses in the Kharanorskaya TPP cooling pond in different temperature conditions are presented in paper. The species diversity of hydrobionts in the heated zone is higher compared to the unheated one. The dominant complex of plankton community in the two thermal zones is similar and includes species with a high temperature optimum. The absence of significant differences in the spatial-temporal dynamics of plankton quantitative indicators is associated with the morphometric features of the reservoir and the mechanical factors influence. The main abiotic factors influencing the distribution of hydrobionts are the water chemical composition in the unheated zone, and are hydrochemical and hydrophysical parameters in the heated zone.

Published: September 2019

Abstract
The characteristic of changes in communities of benthic invertebrates and fish in a small watercourse as its salinisation is given. It is shown the Shannon diversity index and Balushkina chironomid index play the greatest value in assessing the effect of salinity on river communities. There was a violation of the structure of the fish population of the river, expressed in the complete disappearance of fish in the area of intensive receipt of highly mineralized waters.
Sex steroids influence organizational but not functional decidualization of feline endometrial cells in a 3D culture system†
Authors: Wilsterman Kathryn , Bao Xinmiao , Estrada Allegra D , Comizzoli Pierre , Bentley George E 
Published: September 2019

Abstract
Successful implantation requires complex signaling between the uterine endometrium and the blastocyst. Prior to the blastocyst reaching the uterus, the endometrium is remodeled by sex steroids and other signals to render the endometrium receptive. In vitro models have facilitated major advances in our understanding of endometrium preparation and endometrial–blastocyst communication in mice and humans, but these systems have not been widely adapted for use in other models which might generate a deeper understanding of these processes. The objective of our study was to use a recently developed, three-dimensional culture system to identify specific roles of female sex steroids in remodeling the organization and function of feline endometrial cells. We treated endometrial cells with physiologically relevant concentrations of estradiol and progesterone, either in isolation or in combination, for 1 week. We then examined size and density of three-dimensional structures, and quantified expression of candidate genes known to vary in response to sex steroid treatments and that have functional relevance to the decidualization process. Combined sex steroid treatments recapitulated organizational patterns seen in vivo; however, sex steroid manipulations did not induce expected changes to expression of decidualization-related genes. Our results demonstrate that sex steroids may not be sufficient for complete decidualization and preparation of the feline endometrium, thereby highlighting key areas of opportunity for further study and suggesting some unique functions of felid uterine tissues.
The Importance of Biological Parent Coparenting in an American Indian Stepfamily Context
Authors: Ward Kaitlin P , Limb Gordon E 
Published: September 2019

Abstract
A number of protective factors associated with being American Indian exist; however, research shows that American Indians tend to experience higher rates of depressive symptoms than individuals of other racial or ethnic groups. Although prior research has examined sociocultural predictors of American Indian depression, less is known about the influence of familial functioning. This is particularly true for American Indian emerging adults who grew up in stepfamilies. This study examined retrospective data from 203 American Indians raised in stepfamilies on whether perceived coparenting between biological parents (post-stepfamily formation) was related to depression in emerging adulthood. Combining graded response and structural equation modeling, authors found that retrospectively perceived negative coparenting behaviors were significantly associated with depressive symptoms. Findings elucidate a particular risk for American Indians who perceive that their biological parents engage in poor coparenting behaviors post–stepfamily formation. Findings also encourage further research that examines associations between stepfamily functioning and mental health outcomes among American Indians.
Empowered Holistic Nursing Education as the Philosophical Framework for an RN-BS Program: A Six-Year Impact Evaluation Study
Authors: Love Katie 
Published: September 2019

Abstract
The educational structure of many nursing programs is largely monocultural, with a traditional pedagogy. Empowered holistic nursing education (EHNE) creates a learning environment with more cultural responsiveness and support for diverse classrooms. The aim of this study was to determine what impact the theory had on diversification. With EHNE the philosophical framework of a new RN-to-BSN program, student demographic data were collected, along with exit survey questions. A statistically significant increase was found in the diversification of the six cohorts. The EHNE shows potential as a programmatic framework for increasing diversification of the nursing profession.

Published: September 2019

Background:
Prader-Willi syndrome (PWS) is a rare genetic disorder characterized by obesity, hypotonia, feeding difficulties, obesity, musculoskeletal manifestations including scoliosis, and hip dysplasia (HD). The aim of this study was to characterize the clinical and radiographic evolution of HD in the pediatric PWS population.

Methods:
The authors performed a retrospective cohort study of 72 patients (147 anteroposterior pelvic radiographs) between January 2004 and December 2016. Center-edge angle (CEA) of Wiberg, acetabular index (AI), and neck-shaft angle (NSA) were measures in all hips. The relationship between radiographic and demographic parameters of age, sex, and body mass index z-score (BMIzs) were assessed.

Results:
A total of 274 radiographic measurements were performed and analyzed in 72 patients. The mean CEA, AI, and NSA were 21.8±7.1 degrees (range, 5 to 35 degrees), 16.7±7 degrees (range, 5 to 45 degrees), and 142±8.5 degrees (range, 128 to 165 degrees), respectively. HD was diagnosed in 79 (29%) hip radiographs and varied significantly between the age groups (P<0.01). A statistically significant association was identified between age and CEA [β coef, 0.80; 95% confidence interval (CI), 0.6-1; P<0.01], AI (β coef, −0.90; 95% CI, −1.1 to −0.7; P<0.01), and NSA (β coef, −1.11; 95% CI, −1.4 to −0.9; P<0.01) angles. Sex and BMIzs were not identified as independent predictors of radiographic hip angles (P>0.1).

Conclusions:
The present study demonstrated favorable evolution of hip radiographic parameters in the PWS population treated with growth hormone early in development. This finding should prompt orthopedists to consider observation alone in the management algorithm for HD in patients with PWS.

Levels of Evidence:
Level III—a retrospective comparative study.

Authors: Polley Caitlin A. , Oldenburg Hannah Y. , Bergstrom Jennifer L. , Musselman Maureen C. , Pyfferoen Mary D. , Privette Randi A. , Pifer Gina , Bellamkonda Erica 
Published: September 2019

Purpose:
To identify rehabilitation course and functional outcomes in patients with an implanted total artificial heart (TAH).

Methods:
From 2012 to 2015, 10 patients with a TAH implantation at a quaternary care hospital were identified for inclusion. Patients were referred to occupational and physical therapy by the cardiothoracic surgery team. Retrospective data collection included the Boston University Activity Measure for Post-Acute Care (AM-PAC) “6-Clicks” inpatient short form based on the functional status documented weekly. Additional patient factors were reviewed specific to cognition, dysphagia, lymphedema, and skin integrity to obtain a comprehensive understanding of therapy scope.

Results:
The median acute hospitalization length of stay was 68 days. By the time of discharge, AM-PAC 6-Clicks functional mobility scores improved by 48% and AM-PAC 6-Clicks daily activity scores improved by 40%.

Conclusions:
Following TAH implantation, patients appear to safely participate in a comprehensive restorative rehabilitation program in the intensive and progressive care units. Patients with a TAH implant showed improvement in their mobility and activity performance by the time of discharge.

Authors: Hwang Hei-Fen , Chen Chih-Yi , Wei Li , Chen Sy-Jou , Yu Wen-Yu , Lin Mau-Roung 
Published: September 2019

Objective:
To compare the effects of computerized cognitive training (CCT) and tai chi (TC) with usual care (UC) on cognitive functions and secondary outcomes in older adults with traumatic brain injury.

Participants and Settings:
Ninety-six patients aged 55 years and older who had a diagnosis of traumatic brain injury requiring hospital admission.

Design:
Randomized controlled trial.

Main Measures:
The Mattis Dementia Rating Scale (MDRS), Mini-Mental State Examination, modified Telephone Interview of Cognitive Status, and Trail Making Tests A and B.

Results:
Compared with UC, CCT increased scores on the MDRS's total, attention, and memory and those on the Mini-Mental State Examination and Telephone Interview of Cognitive Status over the 6-month intervention; TC increased scores on the MDRS's total and conceptualization and those on the Mini-Mental State Examination over the 6-month intervention, while it also increased scores on the MDRS's total and initiation/preservation and those on the Telephone Interview of Cognitive Status and reduced the time to complete the Trail Making Test B over the 12-month study. Furthermore, compared with UC, CCT increased handgrip strength and TC reduced the time to complete 5 sit-to-stands over the 6-month intervention.

Conclusion:
Both CCT and TC may improve global cognition and different specific cognitive domains in older traumatic brain injury patients; the TC's effect may last for at least an additional 6 months.

CASE REPORT OF ABIOTROPHIA DEFECTIVA ENDOPHTHALMITIS AFTER REPEATED INJECTIONS OF DEXAMETHASONE INTRAVITREAL IMPLANT (OZURDEX)
Authors: Cruz-Iñigo Yousef J. , Klein Kendra , Reddy Rahul K. 
Published: September 2019

Purpose:
To present a case of endophthalmitis caused by Abiotrophia defectiva after repeated injections of dexamethasone intravitreal implant (Ozurdex), in a patient already on systemic immunosuppressive therapy, and discuss the management of this challenging situation.

Methods:
Case report and review of literature.

Results:
A 70-year-old female patient with history of idiopathic pulmonary fibrosis presented for urgent evaluation due to left eye vision loss and mild discomfort 12 days after receiving her seventh dexamethasone implant injection. Ocular history was pertinent for recurrent macular edema resulting from a remote branch vein occlusion. Twelve days after her last injection, visual acuity decreased from 20/30 to counting fingers at 5 feet. Slit-lamp examination showed anterior chamber cell without fibrinoid membranes or hypopyon. Within hours, the patient's clinical appearance progressed. A vitreous tap followed by intravitreal injection of vancomycin (1 mg/0.1 mL) and ceftazidime (2.25 mg/0.1 mL) was performed. The culture from the vitreous sample revealed heavy growth of A. defectiva. Owing to limited improvement, patient was taken to the operating room, and the presence of a full-thickness scleral defect at the site of most recent dexamethasone implant injection was confirmed. Vitrectomy with removal of implant, closure of all sclerotomies, including nonhealing full-thickness scleral defect, and repeated intravitreal antibiotic injection were performed. At the 3-month follow-up, no inflammation was observed, but visual acuity remained poor.

Conclusion:
Intravitreal dexamethasone implant–associated endophthalmitis in the setting of systemic immunosuppression is a rare and challenging situation. Both local and systemic immunosuppression may delay wound healing, predisposing to wound leakage and consequent endophthalmitis. Despite repeated intravitreal antimicrobial injection and vitrectomy with implant removal, A. defectiva endophthalmitis carried a poor visual outcome.
White Sclera Painted Contact Lens for Masking of Conjunctival Neovascularization and Hyperemia Following Cosmetic Eye Whitening Procedure
Authors: Singh Gemini A. , Magone M. Teresa 
Published: September 2019

Abstract:
We describe a case of a 37-year-old veteran with recurrent conjunctival hyperemia 5 years after an eye-whitening conjunctivectomy procedure with mitomycin C who desired to have a repeat procedure by the original surgeon. Instead, the patient was counseled and successfully fitted with white sclera painted contact lenses to mask the regrowth of his conjunctival vasculature with excellent cosmetic results and comfort. Further eye-whitening surgery was, therefore, avoided. We conclude that hand-painted white sclera contact lenses with regular ocular surface health monitoring can be offered as a cosmetic, safer, and economical alternative to patients in order to avoid eye-whitening procedures known to induce ocular ischemia.
Risk Factors for Severe Alcohol Withdrawal Syndrome in an Acute Hospital Population
Authors: Benson George , McCallum Jacqueline , Roberts Nicola J. 
Published: September 2019

Abstract

Background
The literature lacks consensus to the factors that increase the risk of a patient developing severe alcohol withdrawal syndrome (SAWS).

Aim
The study set out to identify the variables that increase the risk of SAWS in patients who have alcohol dependence syndrome.

Methods
A case–control study was designed to investigate the variables associated with SAWS in an acute hospital setting. Three hundred eighty-two case and 382 control patients were randomly selected retrospectively from referrals to the acute addiction liaison nursing service during a 12-month period (January 1, 2015, to December 31, 2015). Statistical significance (p < .05) and association with SAWS were calculated using chi-square, Cramer’s V test, odds ratio, and Levene’s test.

Results
Twenty-four variables have been identified as associated with SAWS development. Five of the 24 variables had a moderate-to-strong association with SAWS risk: Fast Alcohol Screening Test, Glasgow Modified Alcohol Withdrawal Scale score, AWS admission, hours since the last drink, and systolic blood pressure. The study also identified that comorbidity was associated with not developing SAWS.

Conclusion/Recommendations
These findings confirm that noninvasive variables collected in the emergency department are useful in identifying a person’s risk of developing SAWS. The results of this study are a useful starting point in the exploration of SAWS and the development of a tool for use in the emergency department that can stratify risk into high and low and is the next stage of this program of work.
Clients’ Views on the Importance of a Nurse-Led Approach and Nurse Prescribing in the Development of the Healthy Addiction Treatment Recovery Model

Published: September 2019

AbstractGlobally, from America to Europe and beyond, the need for the expansion of the role of nurse practitioners has been recognized within the healthcare professions. However, little emphasis has been placed on assessing the views of clients, and within the addiction services, the voice of clients can be additionally marginalized as a result of treatment philosophies, stigma, and resource constraints. The aims of this study were to establish from clients their nursing needs and to use these findings alongside an objective measurement of clients’ health, to inform the development of a nurse-led treatment model.A cross-sectional survey with open-ended questions on client nursing needs was conducted in 2017 within a representative sample of six clinics in Dublin, Ireland. A convenience sample of 131 clients were interviewed. Interviews were analyzed using thematic analysis.Findings were both as expected and surprising. Clients articulated the role of the nurse in their physical care; however, unexpectedly, clients identified nurses as an essential source of psychological support and expressed the wish for the role to be expanded in terms of managing methadone treatment and accessing additional services and resources.Results contributed to the formation of the nurse-led, client mental-health-focused, Healthy Addiction Treatment Recovery Model for addiction nursing services. In terms of national policies, findings provided new evidence articulated by service users on their desire for the expansion of nurse prescribing in addiction services and an expansion of the role to more adequately address client needs.
