ABSTRACT

Extracellular vesicles (EVs) are secreted by all cells in the CNS, including neurons and astrocytes. EVs are lipid membrane enclosed particles loaded with various bioactive cargoes reflecting the dynamic activities of cells of origin. In contrast to neurons, the specific role of EVs released by astrocytes is less well understood, partly due to the difficulty in maintaining primary astrocyte cultures in a quiescent state. The aim of this study was to establish a human serum-free astrocyte culture system that maintains primary astrocytes in a quiescent state to study the morphology, function, and protein cargoes of astrocyte-derived EVs. Serum-free medium with G5 supplement and serum-supplemented medium with 2% FBS were compared for the culture of commercially available human primary fetal astrocytes. Serum-free astrocytes displayed morphologies similar to in vivo astrocytes, and surprisingly, higher levels of astrocyte markers compared to astrocytes chronically cultured in FBS. In contrast, astrocyte and inflammatory markers in serum-free astrocytes were upregulated 24 h after either acute 2% FBS or cytokine exposure, confirming their capacity to become reactive. Importantly, this suggests that distinct signaling pathways are involved in acute and chronic astrocyte reactivity. Despite having a similar morphology, chronically serum-cultured astrocyte-derived EVs (ADEVs) were smaller in size compared to serum-free ADEVs and could reactivate serum-free astrocytes. Proteomic analysis identified distinct protein datasets for both types of ADEVs with enrichment of complement and coagulation cascades for chronically serum-cultured astrocyte-derived EVs, offering insights into their roles in the CNS. Collectively, these results suggest that human primary astrocytes cultured in serum-free medium bear similarities with in vivo quiescent astrocytes and the addition of serum induces multiple morphological and transcriptional changes that are specific to human reactive astrocytes and their ADEVs. Thus, more emphasis should be made on using multiple structural, molecular, and functional parameters when evaluating ADEVs as biomarkers of astrocyte health.

ABSTRACT

Burn survivors can experience social participation challenges throughout their recovery. The aim of this study was to develop a novel Australian English translation of the Life Impact Burn Recovery Evaluation (LIBRE) Profile, the Aus-LIBRE Profile. This study consisted of three stages: 1) translation of the LIBRE Profile from American to Australian English by Australian researchers/burns clinicians; 2) piloting and cognitive evaluation of the Aus-LIBRE Profile with burn survivors to assess the clarity and consistency of the interpretation of each individual item, and 3) review of the Aus-LIBRE Profile by colleagues who identify as Aboriginal Australians for cross-cultural validation. In stage 2, investigators administered the translated questionnaire to 20 Australian patients with burn injuries in the outpatient clinic (10 patients from xx and 10 patients from yy). Face validity of the Aus-LIBRE Profile was tested in 20 burns survivors (11 females) ranging from 21 to 74 years (median age 43 years). The total body surface area (TBSA) burned ranged from 1% to 50% (median 10%). Twelve language changes were made based on the feedback from the burn clinicians/researchers, study participants and colleagues who identify as Aboriginal Australians. Using a formal translation process, the Aus-LIBRE Profile was adapted for use in the Australian burn population. The Aus-LIBRE Profile will require psychometric validation and testing in the Australian burn patient population before broader application of the scale.

ABSTRACT

LRRK2 is a relatively common genetic risk factor for Parkinson's disease (PD), with six coding variants known to cause familial PD. Non-coding variation at the same locus is also associated with sporadic PD. LRRK2 plays a role in many different intracellular signaling cascades including those involved in endolysosomal function, cytoskeletal dynamics, and Ca2+ homeostasis. PD-causing LRRK2 mutations cause hyperactive LRRK2 kinase activity, resulting in altered cellular signaling. Importantly, LRRK2 is lowly expressed in neurons and prominently expressed in non-neuronal cells in the brain. In this review, we will summarize recent and novel findings on the effects of PD-causing LRRK2 mutations in different nervous system cell types. This review will also provide novel insight into future areas of research at the intersection of LRRK2 cell biology, cell type specificity, and PD.

ABSTRACT

BACKGROUND: Bipolar disorder remains a disabling mental health condition despite the availability of effective treatments. Collaborative chronic care models (CCMs) represent an evidence-based way to structure care for conditions like bipolar disorder. Life Goals Collaborative Care (LGCC) was designed specifically for bipolar disorder, featuring psychoeducation alongside collaborative components (e.g. nurse care management or expert psychiatric consultation). Despite the use of Life Goals across health systems, a systematic review summarizing its effectiveness has never been conducted. METHODS: We conducted a systematic review of randomized controlled trials (RCTs) of LGCC through December 2023 to help guide the field in treating bipolar disorder (PROSPERO: #404581). We evaluated study quality and outcomes in several symptom and quality of life domains. RESULTS: Ten articles describing eight studies met inclusion criteria. All studies featured group-based LGCC; most were compared to treatment as usual (TAU). Three of eight studies found LGCC to be associated with statistically significant effects for the prevention of manic episodes. Most studies finding positive effects featured additional collaborative care components beyond psychoeducation and were conducted in capitated healthcare systems. LIMITATIONS: Limitations include: several types of potential bias in included studies; exclusion of observational studies of LGCC; lack of generalizability to pediatric populations; insufficient studies to conduct subgroup analyses; and low confidence in the quality of the evidence. CONCLUSIONS: In this systematic review, group-based LGCC demonstrated some positive effects for reducing mania recurrence; results for other outcome domains were equivocal. Future studies should investigate one-on-one LGCC, both in person and virtually, to enhance well-being for people with bipolar disorder.

ABSTRACT

BACKGROUND: While the number of reviews of nursing education research has increased over the years, bibliometric studies about these reviews are limited. OBJECTIVES: The purposes were to: (1) examine the number of reviews of nursing education research published from 2018 through 2022, (2) identify journals publishing these reviews, (3) identify the types and topics of reviews in nursing education, and (4) analyze how these reviews are labeled (standard versus nonstandard). DESIGN: This was a bibliometric study of reviews in nursing education. METHODS: The search for reviews in nursing education was done using CINAHL Complete via the EBSCO host platform and was limited to articles published in peer reviewed journals. The results were imported into EndNote, and the title or abstract was used to identify the review type. The categorized reviews were then exported into Microsoft Excel. The titles and abstracts were searched to identify reviews in nursing education, resulting in 600 articles analyzed in this study. The topics of the reviews were identified via natural language processing techniques based on the Medical Subject Headings biomedical vocabulary in the manual tags with each article. RESULTS: The number of reviews has steadily increased over the years. The top journal in which reviews were published was Nurse Education Today (n = 197). Nearly a quarter (n = 149, 24.8 %) of the reviews were integrative, followed by systematic (n = 117, 19.5 %), scoping (n = 117, 19.5 %), and literature (n = 85, 14.2 %). There were 12 main topics: most reviews were on simulation, followed by critical thinking methods and the academic achievement of nursing students. CONCLUSION: This study documented an increase in the number of reviews of nursing education research over the last five years. The most common type was an integrative review, followed by systematic, scoping, and literature. Reviews on simulation were most common.

ABSTRACT

Background: Sustaining healthcare interventions once they have been implemented is a pivotal public health endeavor. Achieving sustainability requires context-sensitive adaptations to evidence-based practices (EBPs) or the implementation strategies used to ensure their adoption. For replicability of adaptations beyond the specific setting in question, the underlying logic needs to be clearly described, and adaptations themselves need to be plainly documented. The goal of this project was to describe the process by which implementation facilitation was adapted to improve the uptake of clinical care practices that are consistent with the collaborative chronic care model (CCM). Method: Quantitative and qualitative data from a prior implementation trial found that CCM-consistent care practices were not fully sustained within outpatient general mental health teams that had received 1 year of implementation facilitation to support uptake. We undertook a multistep consensus process to identify adaptations to implementation facilitation based on these results, with the goal of enhancing the sustainability of CCM-based care in a subsequent trial. The logic for these adaptations, and the resulting adaptations themselves, were documented using two adaptation-oriented implementation frameworks (the iterative decision-making for evaluation of adaptations [IDEA] and the framework for reporting adaptations and modifications to evidence-based implementation strategies [FRAME-IS], respectively). Results: Three adaptations emerged from this process and were documented using the FRAME-IS: (a) increasing the scope of implementation facilitation within the medical center, (b) having the internal facilitator take a greater role in the implementation process, and (c) shortening the implementation timeframe from 12 to 8 months, while increasing the intensity of facilitation support during that time. Conclusions: EBP sustainability may require careful adaptation of EBPs or the implementation strategies used to get them into routine practice. Recently developed frameworks such as the IDEA and FRAME-IS may be used to guide decision-making and document resulting adaptations themselves. An ongoing funded study is investigating the utility of the resulting adaptations for improving healthcare.


Evidence-based treatments may not be sustained after they have been implemented in healthcare settings. To address this, treatments and implementation strategies may need to be adapted to fit the local context or the patient population. Maximizing the usefulness of such adaptations requires documenting the decision-making process. Understanding how an implementation strategy has been adapted for a given study or setting is crucial to ensuring that adaptations don't compromise fidelity to the implementation strategy while enabling its replicability in similar settings. This article uses two adaptation frameworks to describe the process by which implementation facilitation, a common implementation strategy, was adapted to help establish and sustain effective mental health clinical teams in VA medical centers. It is our hope that our description of this process may help healthcare researchers, administrators, and policymakers to describe and document adaptations to implementation strategies in their own settings.

ABSTRACT

For lethal means safety counseling interventions (LMSC) to reduce population-level suicide rates, interventions must be deployed across many settings and populations. We conducted a systematic search in six databases to review the current state of LMSC interventions across study designs, settings, messengers, populations, and injury prevention levels (e.g., universal). Eligibility criteria were: any individual or group receiving a LMSC intervention involving a human-to-human component aiming to influence adult behaviors related to lethal suicide methods, and outcome assessment of storage behaviors and/or suicidal self-directed violence (SDV). Risk of bias was assessed using the Effective Public Health Practice Project (EPHPP) quality assessment tool. A descriptive synthesis approach was used for analysis. Twenty-two studies were included that reported medication and/or firearm storage behaviors and/or SDV following LMSC. Fourteen of the 19 studies assessing behavioral change reported a significant improvement in safe storage behaviors, and all studies measuring acceptability reported that participants found the interventions favorable. Quality of evidence was limited. No studies were rated low risk of bias, and 77% were rated high risk of bias. There was substantial heterogeneity in the settings, populations, injury prevention levels, delivery methods, and intervention elements. Many included studies focused on caregivers of pediatric populations, and few studies assessed SDV outcomes. Higher quality trials conducted across a variety of settings, particularly those focusing on adults at risk of suicide, are needed. There was no funding for this review, and it was preregistered on the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42021230668).

ABSTRACT

BACKGROUND: Sustaining evidence-based practices (EBPs) is crucial to ensuring care quality and addressing health disparities. Approaches to identifying factors related to sustainability are critically needed. One such approach is Matrixed Multiple Case Study (MMCS), which identifies factors and their combinations that influence implementation. We applied MMCS to identify factors related to the sustainability of the evidence-based Collaborative Chronic Care Model (CCM) at nine Department of Veterans Affairs (VA) outpatient mental health clinics, 3-4 years after implementation support had concluded. METHODS: We conducted a directed content analysis of 30 provider interviews, using 6 CCM elements and 4 Integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) domains as codes. Based on CCM code summaries, we designated each site as high/medium/low sustainability. We used i-PARIHS code summaries to identify relevant factors for each site, the extent of their presence, and the type of influence they had on sustainability (enabling/neutral/hindering/unclear). We organized these data into a sortable matrix and assessed sustainability-related cross-site trends. RESULTS: CCM sustainability status was distributed among the sites, with three sites each being high, medium, and low. Twenty-five factors were identified from the i-PARIHS code summaries, of which 3 exhibited strong trends by sustainability status (relevant i-PARIHS domain in square brackets): "Collaborativeness/Teamwork [Recipients]," "Staff/Leadership turnover [Recipients]," and "Having a consistent/strong internal facilitator [Facilitation]" during and after active implementation. At most high-sustainability sites only, (i) "Having a knowledgeable/helpful external facilitator [Facilitation]" was variably present and enabled sustainability when present, while (ii) "Clarity about what CCM comprises [Innovation]," "Interdisciplinary coordination [Recipients]," and "Adequate clinic space for CCM team members [Context]" were somewhat or less present with mixed influences on sustainability. CONCLUSIONS: MMCS revealed that CCM sustainability in VA outpatient mental health clinics may be related most strongly to provider collaboration, knowledge retention during staff/leadership transitions, and availability of skilled internal facilitators. These findings have informed a subsequent CCM implementation trial that prospectively examines whether enhancing the above-mentioned factors within implementation facilitation improves sustainability. MMCS is a systematic approach to multi-site examination that can be used to investigate sustainability-related factors applicable to other EBPs and across multiple contexts.

ABSTRACT

Ataxia telangiectasia (A-T) is a rare, multisystem progressive condition that typically presents in early childhood. In the absence of cure, people with A-T require coordinated multidisciplinary care to manage their complex array of needs and to minimize the disease burden. Although symptom management has proven benefits for this population, including improved quality of life and reduced complications, there is a need for guidance specific to the nursing and allied healthcare teams who provide care within the community. A scoping review, adopting the Joanna Briggs Institute methodology, was undertaken. It aimed to identify and map the available expertise from nursing and allied healthcare and management of children and young people with A-T ≤ 18 years of age. A rigorous search strategy was employed which generated a total of 21,118 sources of evidence, of which 50 were selected for review following screening by experts. A range of interventions were identified that reported a positive impact on A-T-related impairments, together with quality of life, indicating that outcomes can be improved for this population. Most notable interventions specific to A-T include therapeutic exercise, inspiratory muscle training, and early nutritional assessment and intervention. Further research will be required to determine the full potential of the identified interventions, including translatability to the A-T setting for evidence related to other forms of ataxia. Large gaps exist in the nursing and allied health evidence-base, highlighting a need for robust research that includes children and young people with A-T and their families to better inform and optimize management strategies.

ABSTRACT

INTRODUCTION: The output of scholarly publications in scientific literature has increased exponentially in recent years. This increase in literature has been accompanied by an increase in retractions. Although some of these may be attributed to publishing errors, many are the result of unsavory research practices. The purposes of this study were to identify the number of retracted articles in nursing and reasons for the retractions, analyze the retraction notices, and determine the length of time for an article in nursing to be retracted. DESIGN: This was an exploratory study. METHODS: A search of PubMed/MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, and Retraction Watch databases was conducted to identify retracted articles in nursing and their retraction notices. RESULTS: Between 1997 and 2022, 123 articles published in the nursing literature were retracted. Ten different reasons for retraction were used to categorize these articles with one-third of the retractions (n = 37, 30.1%) not specifying a reason. Sixty-eight percent (n = 77) were retracted because of an actual or a potential ethical concern: duplicate publication, data issues, plagiarism, authorship issues, and copyright. CONCLUSION: Nurses rely on nursing-specific scholarly literature as evidence for clinical decisions. The findings demonstrated that retractions are increasing within published nursing literature. In addition, it was evident that retraction notices do not prevent previously published work from being cited. This study addressed a gap in knowledge about article retractions specific to nursing.

ABSTRACT

Polar monomer-induced ß-H elimination is a key elementary step in polar polyolefin synthesis by coordination polymerization but remains underexplored. Herein, we show that a bulky neutral Ni catalyst, 1Ph, is not only a high-performance catalyst in ethylene/acrylate copolymerization (activity up to ∼37,000 kg/(mol·h) at 130 °C in a batch reactor, mol % tBA ∼ 0.3) but also a suitable platform for investigation of acrylate-induced ß-H elimination. 4Ph-tBu, a novel Ni alkyl complex generated after acrylate-induced ß-H elimination and subsequent acrylate insertion, was identified and characterized by crystallography. A combination of catalysis and mechanistic studies reveals effects of the acrylate monomer, bidentate ligand, and the labile ligand (e.g., pyridine) on the kinetics of ß-H elimination, the role of ß-H elimination in copolymerization catalysis as a chain-termination pathway, and its potential in controlling the polymer microstructure in polar polyolefin synthesis.

ABSTRACT

The convergence of Human Immunodeficiency Virus (HIV) and tuberculosis (TB) represents a considerable global public health challenge. The concurrent infection of HIV and TB in pregnant women not only intensifies the transmission of HIV from mother to fetus but also engenders adverse outcomes for maternal health, pregnancy, and infant well-being, necessitating the implementation of integrated strategies to effectively address and manage both diseases. In this article, we review the pathophysiology, clinical presentation, treatment, and management of HIV/TB coinfection during pregnancy, the postpartum period, and lactation and highlight the differences compared to the general population.

ABSTRACT

INTRODUCTION: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a multisystem chronic disease estimated to affect 836,000-2.5 million individuals in the United States. Persons with ME/CFS have a substantial reduction in their ability to engage in pre-illness levels of activity. Multiple symptoms include profound fatigue, post-exertional malaise, unrefreshing sleep, cognitive impairment, orthostatic intolerance, pain, and other symptoms persisting for more than 6 months. Diagnosis is challenging due to fluctuating and complex symptoms. ME/CFS Common Data Elements (CDEs) were identified in the National Institutes of Health (NIH) National Institute of Neurological Disorders and Stroke (NINDS) Common Data Element Repository. This study reviewed ME/CFS CDEs item content. METHODS: Inclusion criteria for CDEs (measures recommended for ME/CFS) analysis: 1) assesses symptoms; 2) developed for adults; 3) appropriate for patient reported outcome measure (PROM); 4) does not use visual or pictographic responses. Team members independently reviewed CDEs item content using the World Health Organization International Classification of Functioning, Disability and Health (ICF) framework to link meaningful concepts. RESULTS: 119 ME/CFS CDEs (measures) were reviewed and 38 met inclusion criteria, yielding 944 items linked to 1503 ICF meaningful concepts. Most concepts linked to ICF Body Functions component (b-codes; n = 1107, 73.65%) as follows: Fatiguability (n = 220, 14.64%), Energy Level (n = 166, 11.04%), Sleep Functions (n = 137, 9.12%), Emotional Functions (n = 131, 8.72%) and Pain (n = 120, 7.98%). Activities and Participation concepts (d codes) accounted for a smaller percentage of codes (n = 385, 25.62%). Most d codes were linked to the Mobility category (n = 69, 4.59%) and few items linked to Environmental Factors (e codes; n = 11, 0.73%). DISCUSSION: Relatively few items assess the impact of ME/CFS symptoms on Activities and Participation. Findings support development of ME/CFS-specific PROMs, including items that assess activity limitations and participation restrictions. Development of psychometrically-sound, symptom-based item banks administered as computerized adaptive tests can provide robust assessments to assist primary care providers in the diagnosis and care of patients with ME/CFS.

ABSTRACT

BACKGROUND: Rapeseed protein isolate is used in the food industry, and heating is often used during rapeseed processing. However, the digestible indispensable amino acid score (DIAAS) for heat-treated rapeseed protein isolate is unknown. The present study aimed to test the hypothesis that heating rapeseed protein isolate improves protein quality resulting in DIAAS that is greater than for pea and rice protein concentrates, and comparable to that of soy and whey protein isolates. RESULTS: Standardized ileal digestibility (SID) of amino acids (AA), except leucine and methionine, was not different between heat-treated rapeseed protein isolate and soy protein isolate, but SID of most AA was greater (P < 0.001) for heat-treated rapeseed protein isolate than for brown rice protein concentrate, pea protein concentrate, rapeseed protein isolate and soy protein isolate, but not whey protein isolate. Non-heated rapeseed protein isolate had a reduced (P < 0.001) DIAAS for 6-month-old to 3-year-old children compared with soy protein isolate, but this was greater (P < 0.001) than for pea and brown rice protein concentrates. The DIAAS for heat-treated rapeseed protein isolate was greater (P < 0.001) than for non-heated rapeseed protein isolate for all age groups. Heat-treated rapeseed protein isolate and whey protein isolate had a DIAAS > 100 for individuals older than 3 years. CONCLUSION: Rapeseed protein isolate had a DIAAS comparable to soy protein isolate, but heat-treated rapeseed protein isolate and whey protein isolate had DIAAS ≥ 100, qualifying these proteins as 'excellent'. Rice and pea protein concentrates had DIAAS < 75. © 2023 Society of Chemical Industry.

ABSTRACT

An experiment was conducted to test the hypothesis that inclusion of spray dried plasma (SDP) in diets increases apparent total tract digestibility (ATTD) and/or the standardized total tract digestibility (STTD) of gross energy (GE) and nutrients in diets for young pigs, and that ATTD of energy and nutrients or STTD of P in individual ingredients are additive in diets containing SDP. Eighty barrows (body weight: 9.30 ± 0.97 kg) were housed in individual metabolism crates and allotted to 1 of 10 diets in a randomized complete block design with 8 replicate pigs per diet. Four diets were prepared without SDP and contained ingredients commonly used in the United States, Canada, the European Union, or Asia. Four additional diets were prepared by mixing 94% of the previous four diets and 6% SDP. A diet containing SDP as the sole source of P and a P-free diet were also formulated. The ATTD of GE and nutrients and the STTD of P were calculated in all diets except the P-free diet and for the four regional diets containing 6% SDP, values were also predicted from the digestibility obtained in SDP alone and the regional diets without SDP. Differences between measured and predicted values for digestibility of GE and nutrients were also calculated. An interaction was observed between SDP and region for the ATTD of soluble dietary fiber where the digestibility decreased (P < 0.05) for pigs fed the U.S. diet with 6% SDP compared with 0% SDP, but that was not the case for the other regional diets. There was no interaction for the ATTD of GE, N, insoluble dietary fiber (IDF), total dietary fiber (TDF), Ca, and P or the STTD of P, but the ATTD and STTD values were greater (P < 0.05) or tended to be greater (P < 0.10%) when 6% SDP was included in the diet compared with diets with 0% SDP. The ATTD of GE, IDF, TDF, and P, and the STTD of P was greater (P < 0.05) for the Asia diet compared with the other diets regardless of inclusion of SDP. The measured ATTD of IDF and TDF was greater (P < 0.05) than the predicted values for the U.S. and European Union diets, and the measured ATTD of GE, N, Ca, and P and the STTD of P was greater (P < 0.05) than the predicted values for the Asia diet. In conclusion, addition of 6% SDP to a diet will increase the ATTD of energy and nutrients and the STTD of P in diets for weanling pigs, and in some cases, the measured ATTD of energy and nutrients or the STTD of P by pigs fed diets containing SDP is greater than predicted from individual ingredients.

ABSTRACT

INTRODUCTION AND IMPORTANCE: Endometriomas are the most common presenting subtype of endometriosis. Although most endometriomas are asymptomatic, patients can rarely present acutely with spontaneous rupture causing diffuse peritonitis and severe systemic inflammatory response. CASE PRESENTATION: Here we describe a case of ruptured endometriomas in a 26-year-old nulligravid female with a history of heavy menses, progressive abdominal distension, and a recent urinary tract infection. The patient presented to the emergency department with upper abdominal pain radiating to her back with associated nausea. Computed tomography (CT) scan demonstrated diffuse ascites with a large, multilobulated, and multicystic septated mass arising in the right pelvis and extending into the lower abdomen. Findings were concerning for peritoneal carcinomatosis and the patient was admitted for evaluation. She developed progressive signs of sepsis and was emergently brought to the operating room for surgical exploration on hospital day (HD) number two. She was found to have ruptured pelvic cysts arising from both ovaries with diffuse contamination of the abdomen by cyst contents and bilateral salpingo-oophorectomy (BSO) was performed. Final pathology demonstrated benign bilateral endometriomas. CLINICAL DISCUSSION: Endometrioma rupture is extremely rare and imaging findings may appear to represent disseminated peritoneal malignancy. CT findings demonstrating a pelvic mass with concurrent ascites should raise clinical suspicion for ruptured endometrioma, particularly in younger patients. CONCLUSION: Prompt surgical exploration and complete resection of pathologic tissue may be necessary for diagnosis and treatment in some patients with clinical deterioration related to perforated endometriomas. Combined oral contraceptives are recommended in the postoperative period.

ABSTRACT

Spray dried plasma (SDP) is commonly used in phase 1 diets for weanling pigs, but it is unknown if SDP affects energy or nutrient digestibility of the subsequent diet. Therefore, two experiments were conducted to test the null-hypothesis that inclusion of SDP in a phase 1 diet fed to weanling pigs will not affect energy or nutrient digestibility of a phase 2 diet without SDP. In experiment 1, 16 newly weaned barrows with an initial body weight (BW) of 4.47 ± 0.35 kg were randomly allotted to a phase 1 diet without SDP or a diet including 6% SDP for 14 d. Both diets were fed on an ad libitum basis. All pigs (BW: 6.92 ± 0.42 kg) had a T-cannula surgically inserted in the distal ileum, moved to individual pens, and fed the common phase 2 diet for 10 d with ileal digesta collection on days 9 and 10. In experiments 2, 24 newly weaned barrows (initial BW: 6.60 ± 0.22 kg) were randomly allotted to phase 1 diets without SDP or a diet containing 6% SDP for 20 d. Both diets were provided on an ad libitum basis. All pigs (BW: 9.37 ± 1.40 kg) were then moved to individual metabolism crates and fed the common phase 2 diet for 14 d with the initial 5 d being the adaptation period to the diet followed by 7 d of fecal and urine collection according to the marker-to-marker procedure. The apparent ileal digestibility (AID) of starch, crude protein (CP), amino acids (AA), and acid hydrolyzed ether extract (AEE), was determined in experiment 1, and the apparent total tract digestibility (ATTD) of gross energy (GE), insoluble-, soluble-, and total-dietary fiber, Ca, and P, and the retention and biological value of N were determined in experiment 2. The statistical model included diet as fixed effect and block and pig within block as random effects. Results of experiment 1 indicated that the AID of starch, CP, AEE, and AA in phase 2 were not affected by phase 1 treatment. Results of experiment 2 indicated that the ATTD of GE, insoluble-, soluble-, and total-dietary fiber, Ca, and P and N retention and biological value in phase 2 were also not affected by phase 1 treatment. In conclusion, feeding weanling pigs a diet with 6% SDP in phase 1 did not affect the AID or ATTD of energy and nutrients in a phase 2 diet without SDP.


Highly digestible and palatable ingredients are usually included in diets for newly weaned pigs to improve feed consumption and nutrient digestibility. Weaning typically causes a decrease in digestion and nutrient absorption, but inclusion of sprayed dried plasma (SDP) in phase 1 diets to weanling pigs may increase nutrient digestibility. However, data to demonstrate possible effects of including SDP to a phase 1 diet for newly weaned pigs on nutrient digestibility of a phase 2 diet without SDP are limited. Therefore, two experiments were conducted to test the hypothesis that inclusion of SDP in a phase 1 diet fed to weanling pigs does not affect the energy or nutrient digestibility of a phase 2 diet without SDP. Results of the two experiments demonstrated that weaned pigs fed a phase 1 diet with 6% SDP did not increase nutrient or energy digestibility of phase 2 compared with pigs fed diets without SDP, indicating that SDP had no carryover effects on nutrient digestibility. Therefore, it appears that feeding SDP in phase 1 diets to weanling pigs does not cause long-term intestinal changes that will affect digestibility of nutrients and energy in phase 2.

ABSTRACT

BACKGROUND: Shock index (SI) predicts outcomes after trauma. Prior single-center work demonstrated that emergency medical services (EMSs) initial SI was the most accurate predictor of hospital outcomes in a rural environment. This study aimed to evaluate the predictive ability of SI in multiple rural trauma systems with prolonged transport times to a definitive care facility. METHODS: This retrospective review was performed at four American College of Surgeons-verified level 1 trauma centers with large rural catchment basins. Adult trauma patients who were transferred and arrived >60 minutes from scene during 2018 were included. Patients who sustained blunt chest or abdominal trauma were analyzed. Subjects with missing data or severe head trauma (Abbreviated Injury Scale score, >2) were excluded. Poisson and binomial logistic regression were used to study the effect of SI and delta shock index (∆SI) on outcomes. RESULTS: After applying the criteria, 789 patients were considered for analysis (502 scene patients and 287 transfers). The mean Injury Severity Score was 8 (interquartile range, 6) for scene and 8.9 (interquartile range, 5) for transfers. Initial EMSs SI was a significant predictor of the need for blood transfusion and intensive care unit care in both scene and transferred patients. An increase in ∆SI was predictive of the need for operative intervention ( p < 0.05). There were increased odds for mortality for every 0.1 change in EMSs SI; those changes were not deemed significant among both scene and transfer patients ( p < 0.1). CONCLUSION: Providers must maintain a high level of clinical suspicion for patients who had an initially elevated SI. Emergency medical services SI is a significant predictor for use of blood and intensive care unit care, as well as mortality for scene patients. This highlights the importance of SI and ∆SI in rural trauma care. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

ABSTRACT

This qualitative study documents and analyzes COVID-19's impacts on burn care in twelve nations. Burn care saw valuable improvements in surgical techniques, skin grafting, and other acute treatments during the decades before the COVID-19 pandemic which increased severely burned patients' survival rates and quality of life. Detailed interviews, conducted in the 12 nations reveal that the COVID-19 pandemic greatly affected the delivery of acute and rehabilitation services for burn patients. Resources have been suctioned away from non-COVID healthcare and burn care has not been spared. Acute, post-acute rehabilitation, and mental health services have all suffered. Weak preparation has deeply burdened health care services in most nations, resulting in lower access to care. Access problems have accelerated innovations like telehealth in many nations. The spread of misinformation through social and traditional media has contributed to the varied responses to COVID-19. This compounded problems in health care delivery. Burn care providers delivered services for survivors during extremely difficult circumstances by continuing to furnish acute and long-term services for patients with complex disease. Emphasis on future pandemic preparedness will be vital because they undermine all aspects of burn care and patient outcomes. As the COVID-19 pandemic continues to unfold around the world, it will be important to continue to monitor and analyze the adaptability of nations, health care systems, and burn care providers.

ABSTRACT

Our goal was to investigate the sustainability of care practices that are consistent with the collaborative chronic care model (CCM) in nine outpatient mental health teams located within US Department of Veterans Affairs (VA) medical centers, three to four years after the completion of CCM implementation. We conducted qualitative interviews (N = 30) with outpatient mental health staff from each of the nine teams. We based our directed content analysis on the six elements of the CCM. We found variable sustainability of CCM-based care processes across sites. Some care processes, such as delivery of evidence-based psychotherapies (EBPs) and use of measurement-based care (MBC) to guide clinic decision-making, were robustly maintained or even expanded within participating teams. In contrast, other care processes-which had in some cases been developed with considerable effort-had not been sustained. For example, care manager roles were diminished in scope or eliminated completely in response to workload pressures, frontline care needs, or the COVID-19 pandemic. Similarly, processes for engaging Veterans more fully in decision-making had generally been scaled back. Leadership support in the form of adequate team staffing and time to conduct team meetings were seen as crucial for sustaining CCM-consistent care. Given the potential impact of leadership turnover on sustainability in mental health, future efforts to implement CCM-based mental health care should strive to involve multiple leaders in implementation and sustainment efforts, lest one key departure undo years of implementation work. Our results also suggest that implementing CCM processes may best be conceptualized as a partnership across multiple levels of medical center leadership.
