RESUMO

Over the past 10 years, there has been a rapid expansion of legal and legislative changes in abortion care provision for advanced practice clinicians (APCs), including nurse practitioners, midwives, and physician associates (formerly physician assistants), with most of that expansion occurring in the last several years. This expansion has occurred via several routes (eg, legislative, popular vote, court decision, attorney general opinion), and the patchwork of legal statuses nationally creates confusion for clinicians who are unclear on current regulations. This review explores the historical context of abortion practice for APCs, as well as the primary philosophical and legal concepts relevant to this role development. Since 2012, the number of states permitting abortion practice by APCs has more than quintupled, and the changes to abortion law in the United States in the wake of the 2022 Supreme Court decision in the case of Dobbs v. Jackson Women's Center creates a new imperative to understand the role of APCs in accessing abortion care. Additionally, although the research on abortion safety for APC abortion providers is well-established, the physician-centered paradigm of abortion care has limited the ability of APCs to develop expertise in this essential public and clinical health service.

RESUMO

AIM: To examine the barriers and facilitators nurses experience in addressing social needs in the United States and the associated outcomes of addressing these needs in adults in the ambulatory care setting. DESIGN: A systematic review with inductive thematic and narrative synthesis. DATA SOURCES: PubMed, CINAHL, Web of Science, and Embase from 2010 through 2021. REVIEW METHODS: Cochrane Handbook of Systematic Reviews; Risk of Bias-CASP and the JBI checklist; Certainty of evidence-GRADE-CERQual assessment. RESULTS: After duplicates were removed, 1331 titles and abstracts were screened, and a full-text review was performed on 189 studies. Twenty-two studies met inclusion criteria. The most frequently cited barriers to addressing social needs were lack of resources, workload burden, and lack of education in social needs. The most cited facilitators were engaging the person and family in decision-making, a well-integrated standardized data tracking and referral documentation system, clear communication within the clinic and with community partners, and specialized education and training. Seven studies measured the nurse's impact of screening for and addressing social needs, and outcomes improved in most of these studies. CONCLUSION: Barriers and facilitators specific to nurses in the ambulatory setting and associated outcomes were synthesized. Limited evidence suggests that screening for social needs by nurses may impact outcomes by decreasing hospitalizations, decreasing emergency department utilization, and improving self-efficacy towards medical and social services navigation. IMPACT: These findings inform practice and facilitate changes within nursing towards care that accounts for a person's individual social needs in ambulatory care settings and are most directly applicable to nurses and administrators in the United States. REPORTING METHOD: PRISMA guidelines, supplemented by the ENTREQ and SWiM guidelines. NO PATIENT OR PUBLIC CONTRIBUTION: This systematic review is the result of work performed by the four authors exclusively.

RESUMO

PURPOSE: To determine what is known about climate change health effects for gender diverse (GD) populations, and identify gaps in research, practice, education, and policy. DESIGN/METHODS: A scoping review was conducted. FINDINGS: Twenty-seven information sources met inclusion criteria. Natural disasters and inadequate disaster relief responses were identified as an overarching health threat for GD populations. Within this theme, four sub-themes emerged. No other climate-related health impacts for GD populations were mentioned in the sources reviewed. CONCLUSIONS: There are major gaps in knowledge about health implications of climate change for GD populations. Gender-sensitive data must be collected in order to better understand these threats and detect disparities. Currently most practice and policy recommendations focus on disaster relief. More research on the broad effects of climate change on GD populations is urgently needed to inform practice and policy. CLINICAL RELEVANCE: Climate change amplifies existing risks of adverse health outcomes. Because of discrimination, stigma, and violence, gender diverse individuals are particularly vulnerable.

RESUMO

Interest in self-management approaches to abortion with pills in the United States preceded the coronavirus disease 2019 (COVID-19) pandemic and has accelerated during this global health crisis. Coupled with the unclear future of legal abortion in the United States, clinical care providers need to be aware of the range of self-managed abortion approaches and of the varying levels of engagement with the formal health care system they entail. This article is intended to serve as a resource to inform providers of the current landscape of abortion with pills in the United States, while also describing possible shifts in the future that may result due to the ongoing pandemic and the continuing erosion of access to abortion care and services.

RESUMO

Dietary fibre and probiotics may play a role in the management of diverticular disease. This systematic review synthesises the evidence on the effects of dietary fibre modifications, with or without the use of probiotics, on the incidence in older adults of asymptomatic (AS) or symptomatic uncomplicated diverticular disease (SUDD), as well as on gastrointestinal function and symptoms. Five electronic databases were searched for studies through to December 2018. The body of evidence was appraised using the Cochrane Risk of Bias tool and GRADE. Nine studies were included, with mean sample ages ranging from 57 to 70 years, and three meta-analyses were performed. Only one study, with high risk of bias, measured the effect of dietary fibre on the incidence of diverticulitis. Dietary fibre supplementation improved stool weight (MD: 42 g/day, P < 0.00001; GRADE level of evidence: low), but had no significant effect on gastrointestinal symptoms (SMD: -0.13, P = 0.16; GRADE level of evidence: low) or stool transit time (MD: -3.70, P = 0.32 GRADE level of evidence: low). There was "very low" confidence for the body of evidence supporting symbiotics for AS or SUDD. A high dietary fibre intake, in line with dietary guidelines, may improve gastrointestinal function and is recommended in patients with AS or SUDD. Dietary fibre supplementation should be considered on an individualised basis to improve bowel function, while any recommendation on symbiotic supplements requires further well-designed research. Future studies should also measure the impact on the incidence of diverticulitis.

RESUMO

Malnutrition is a common and complex problem in hospitals. This study used an integrated knowledge translation approach to develop, implement, and evaluate a multifaceted, tailored intervention to improve nutrition care, delivery, and intake among acute medical inpatients. This observational, pre-post study was conducted in a medical ward at a public hospital in Australia. The intervention was co-developed with key stakeholders and targeted three levels: individuals (nutrition intake magnets at patient bedsides), the ward (multidisciplinary hospital staff training), and the organisation (foodservice system changes). Observational data were collected pre- and post-intervention on patient demographics, food intakes, and the mealtime environment. Data were entered into SPSS and analysed using descriptive and inferential statistics. Ethical approval was gained through the hospital and university ethics committees. A total of 207 patients were observed; 116 pre- and 91 post-intervention. After intervention implementation, patients' mean energy and protein intakes (in proportion to their estimated requirements) were significantly higher and the number of patients eating adequately doubled (p < 0.05). In summary, a multifaceted, pragmatic intervention, tailored to the study context and developed and implemented alongside hospital staff and patients, seemed to be effective in improving nutrition practices and patient nutrition intakes on an acute medical ward.

RESUMO

Hospital-acquired malnutrition is a significant issue with complex aetiology, hence nutrition interventions must be multifaceted and context-specific. This paper describes the development, implementation and process evaluation of a complex intervention for improving nutrition among medical patients in an Australian hospital. An integrated knowledge translation (iKT) approach was used for intervention development, informed by previous research. Intervention strategies targeted patients (via a nutrition intake monitoring system); staff (discipline-specific training targeting identified barriers); and the organisation (foodservice system changes). A process evaluation was conducted parallel to implementation assessing reach, dose, fidelity and staff responses to the intervention using a mixed-methods design (quantitative and qualitative approaches). Staff-level interventions had high fidelity and broad reach (61% nurses, 93% foodservice staff and all medical staff received training). Patient and organisation interventions were implemented effectively, but due to staffing issues, only reached around 60% of patients. Staff found all intervention strategies acceptable with benefits to practice. This study found an iKT approach useful for designing a nutrition intervention that was context-specific, feasible and acceptable to staff. This was likely due to engagement of multiple disciplines, identifying and targeting specific areas in need of improvement, and giving staff frequent opportunities to contribute to intervention development/implementation.

RESUMO

In practice, nutrition recommendations vary widely for inpatient and discharge management of acute, uncomplicated diverticulitis. This systematic review aims to review the evidence and develop recommendations for dietary fibre modifications, either alone or alongside probiotics or antibiotics, versus any comparator in adults in any setting with or recently recovered from acute, uncomplicated diverticulitis. Intervention and observational studies in any language were located using four databases until March 2017. The Cochrane Risk of Bias tool and GRADE were used to evaluate the overall quality of the evidence and to develop recommendations. Eight studies were included. There was "very low" quality evidence for comparing a liberalised and restricted fibre diet for inpatient management to improve hospital length of stay, recovery, gastrointestinal symptoms and reoccurrence. There was "very low" quality of evidence for using a high dietary fibre diet as opposed to a standard or low dietary fibre diet following resolution of an acute episode, to improve reoccurrence and gastrointestinal symptoms. The results of this systematic review and GRADE assessment conditionally recommend the use of liberalised diets as opposed to dietary restrictions for adults with acute, uncomplicated diverticulitis. It also strongly recommends a high dietary fibre diet aligning with dietary guidelines, with or without dietary fibre supplementation, after the acute episode has resolved.

RESUMO

In this study, we aim to investigate the change in photon emission statistics of single CdSe/CdS core/shell quantum dots (QDs) on dielectric modified gold nanoparticle (NP) substrates as a function of the excitation wavelength. Photons emitted from single QDs are typically "anti-bunched" and are independent of the excitation wavelength. However, when QDs are coupled to plasmonic substrates, even at the low excitation power regime, we observed a significant change in photoluminescence emission behavior of single QDs; i.e. the emission transformed from incomplete photon anti-bunched to bunched when the excitation was changed from "off" to "on" plasmon resonance. Theoretical studies based on electrodynamics modeling suggested that for the QD-Au NP system, the quantum yield of single excitons decreases while that of biexcitons increases. In addition, when excited at the "on" resonance condition, the absorption is highly enhanced, resulting in an increased population of higher order excitons of the QDs. The higher order exciton emission was directly observed as an additional peak appeared at the blue side of the exciton peak of single QDs. The combined effect of the change in quantum yield and the increase in the absorption cross-section switches the photons emitted by single QDs from anti-bunched to bunched. These results provided direct evidence that not only the plasmonic nanostructures but also the excitation wavelength can effectively control the photon emission statistics of single QDs in the hybrid metal-semiconductor system. Manipulating the multiexciton-plasmon interaction in a hybrid complex like this could possibly open up new doors for applications such as entangled photon pair generation and plasmon-enhanced optoelectronic devices.

RESUMO

BACKGROUND: Abdominal aortic aneurysms can be either treated by an open abdominal aortic aneurysm repair or an endovascular repair. Comparing clinical predictors of outcomes and those which influence survival rates in the long term is important in determining the choice of treatment offered and the decision-making process with patients. AIMS: To determine the influence of pre-existing clinical predictors and perioperative determinants on late survival of elective open abdominal aortic aneurysm repair and endovascular repair at a tertiary hospital. METHODS: Consecutive patients undergoing elective abdominal aortic aneurysm repair from 1990 to 2013 were included. Data were collected from a prospectively acquired database and death data were gathered from the Queensland state death registry. Pre-existing risks and perioperative factors were assessed independently. Kaplan-Meier and Cox regression modeling were performed. RESULTS: During the study period, 1340 abdominal aortic aneurysms were repaired electively, of which 982 were open abdominal aortic aneurysm repair. The average age was 72.4 years old and 81.7% were males. The cumulative percentage survival rates for open abdominal aortic aneurysms repair at 5, 10, 15 and 20 years were 79, 49, 31 and 22, respectively. The corresponding 5-, 10- and 15-year survival rates for endovascular repair were not significantly different at 75, 49 and 33%, respectively (P = 0.75). Predictors of reduced survival were advanced age, American Society of Anaesthesiology scores, chronic obstructive pulmonary disease, renal impairment, bifurcated grafts, peripheral vascular disease and congestive heart failure. CONCLUSIONS: Open repair offers a good long-term treatment option for patients with an abdominal aortic aneurysm and in our experience there is no significant difference in late survival between open abdominal aortic aneurysms repair and endovascular repair. Consideration of the factors identified in this study that predict reduced long-term survival for open abdominal aortic aneurysms repair and endovascular repair should be considered when deciding repair of abdominal aortic aneurysm.

RESUMO

In this work, we systematically investigated the plasmonic effect on blinking, photon antibunching behavior and biexciton emission of single CdSe/CdS core/shell quantum dots (QDs) near gold nanoparticles (NPs) with a silica shell (Au@SiO2). In order to obtain a strong interaction between the plasmons and excitons, the Au@SiO2 NPs and CdSe/CdS QDs of appropriate sizes were chosen so that the plasmon resonance overlaps with the absorption and emission of the QDs. We observed that in the regime of a low excitation power, the photon antibunching and blinking properties of single QDs were modified significantly when the QDs were on the Au@SiO2 substrates compared to those on glass. Most significantly, second-order photon intensity correlation data show that the presence of plasmons increases the ratio of the biexciton quantum yield over the exciton quantum yield (QYBX/QYX). An electrodynamics model was developed to quantify the effect of plasmons on the lifetime, quantum yield, and emission intensity of the biexcitons for the QDs. Good agreement was obtained between the experimentally measured and calculated changes in QYBX/QYX due to Au@SiO2 NPs, showing the validity of the developed model. The theoretical studies also indicated that the relative position of the QDs to the Au NPs and the orientation of the electric field are important factors that regulate the emission properties of the excitons and biexcitons of QDs. The study suggests that the multiexciton emission efficiency in QD systems can be manipulated by employing properly designed plasmonic structures.

RESUMO

OBJECTIVE: Most abdominal aortic aneurysms (AAAs) contain intraluminal thrombus (ILT), which has been demonstrated to contain proteolytic enzymes and proinflammatory cytokines implicated in AAA progression and rupture. In animal models, anticoagulants have been shown to limit AAA progression. Whether ILT plays a role in AAA rupture is unknown. The aim of this study was to compare the volume of ILT in patients with ruptured and intact AAAs. METHODS: We matched by maximum axial diameter alone, on a 1:2 basis, 28 patients with ruptured AAAs and 56 patients with intact AAAs. Total infrarenal aortic volume and ILT volume were measured from computed tomography angiograms using a previously validated and reproducible semiautomated workstation protocol. Clinical risk factors were also recorded. The Mann-Whitney U test was used to compare ILT volumes between patients with ruptured and intact AAAs. RESULTS: Median (interquartile range [IQR]) maximum AAA diameter (84.0 [77.5-93.9] mm vs 82.6 [77.1-93.3] mm; P = .769) and median (IQR) total AAA volume (372.8 [277.4-486.1] cm(3) vs 358.4 [289.1-563.4] cm(3); P = .977) were similar in patients with ruptured and intact AAAs. Median (IQR) AAA ILT volume was similar in patients with ruptured (152.7 [84.8-252.4] cm(3)) and intact (180.1 [89.9-254.8] cm(3); P = .414) AAAs. CONCLUSIONS: This study suggests that ILT volume is not different in ruptured and intact AAAs.

RESUMO

OBJECTIVES: Carpal tunnel syndrome (CTS) is a common entrapment neuropathy of the median nerve at the wrist that is characterized by pain, paresthesias, weakness, and loss of dexterity. This pilot study was conducted to evaluate the heated lidocaine/tetracaine patch (HLT patch) as a conservative treatment for pain of CTS. METHODS: Twenty adult patients (mean age = 44 ± 12 years) with pain secondary to unilateral CTS and electrodiagnostic evidence of mild-to-moderate CTS enrolled in this open-label study. Patients were treated with a single HLT patch placed over the junction of forearm and wrist on the palmar aspect of the wrist twice daily (morning and evening at 12-hour intervals) for 2 hours. At baseline and during the 2-week study, patients graded their pain intensity with an 11-point numerical rating scale (0 = no pain, 10 = worst imaginable pain). Pain interference with general activity, work, and sleep was evaluated with a similar 0-to-10-point scale. RESULTS: Fifteen patients completed the 14-day treatment period. Mean average pain intensity score decreased from 5.1 ± 1.5 at baseline to 2.5 ± 1.6 at end of study in the per-protocol population (P < 0.001). Two-thirds of the patients demonstrated clinically meaningful pain relief (≥ 30% reduction in average pain score), with 40% of the patients reaching this threshold by the third treatment day. Similar improvements were observed for pain interference scores. The HLT patch was generally well tolerated. CONCLUSION: The HLT patch resulted in clinically meaningful reduction in pain intensity in the majority of patients with mild-to-moderate CTS and may represent a targeted nonsurgical treatment for pain associated with CTS.

RESUMO

OBJECTIVES: Our objective was to assess the short- and long-term outcome for patients after carotid body tumor (CBT) resection and discuss the potential pitfalls of the treatment. METHODS: An analysis was undertaken of all patients who underwent CBT resection at Royal Brisbane and Women's Hospital and Greenslopes Private Hospital between 1982 and 2007. Primary tumor characteristics, surgical technique, and outcomes were recorded and analyzed. RESULTS: A total of 49 consecutive CBT resections (2 recurrent tumors) were carried out in 39 patients (26 women [56%]) who were a mean age of 49 years (range, 17-75 years). A nontender neck mass was the presenting complaint in 85%, followed by screening in familial or contralateral tumors in 26%. Familial cases occurred in 11 patients (28%). There were no operative deaths. Complications occurred in 13 of the 49 operations (27%), predominantly temporary nerve palsies and were more likely to occur in tumors of large volume or in cases of removal of coexisting vagal tumors. Malignant disease was present in seven cases (15%). All patients have been followed-up postoperatively for a mean of 11 years (range, 2-26 years). Metachronous paragangliomas have been discovered in six patients, all with familial disease. CONCLUSIONS: Early resection of carotid body tumors should be undertaken while still small to minimize the risk of neural injury, which increases with tumor size. In cases of bilateral CBT, we recommend that the smaller tumor be resected first, before the staged resection of the larger contralateral tumor. In familial or bilateral tumor cases, other synchronous and metachronous paragangliomas should be excluded. Mandatory lifelong follow-up is essential.

RESUMO

BACKGROUND: This study was undertaken to document the results of our current practice of open mesenteric revascularization to enable comparison with the recent trend of percutaneous endovascular therapy for the treatment of chronic mesenteric ischemia. METHODS: Patients were identified via operation code data as well ongoing audit data from 1992 until 2006. Only patients with a history of chronic mesenteric ischemia secondary to atherosclerosis for 3 months or longer were included in the study. Follow-up data have been collected prospectively and include clinical examination and history, as well as graft surveillance consisting of mesenteric duplex ultrasonography, computed tomography, and/or angiography every 6 months for 3 years and then yearly thereafter. RESULTS: Thirty-nine consecutive patients underwent 41 open revascularization procedures for chronic mesenteric ischemia, comprising 67 bypass grafts. The mean patient age was 65 years (range, 45-85 years), and 44% (n = 17) were male. Symptoms were present on average for 11 months (range, 4-48 months) before treatment. The average weight loss was 11.4 kg, and three patients (7.6%) also had evidence of ischemic enteritis. There was one perioperative death, thus giving a perioperative mortality rate of 2.5%. Perioperative morbidity occurred in five patients (12.2%). Primary graft patency was 92% at 5 years. Seven patients died during follow-up, which ranged from 4 to 161 months (mean, 39 months)-one (2.5%) from mesenteric ischemia. Two (5%) other patients have had recurrent mesenteric ischemic symptoms. CONCLUSIONS: Open surgical mesenteric revascularization by bypass grafting for atherosclerotic-induced chronic mesenteric ischemia can be performed with low mortality and morbidity and provides excellent long-term primary patency rates and symptom-free outcomes. Pending more data on the acute and long-term results of endovascular techniques, open mesenteric revascularization remains the gold standard for most patients with chronic mesenteric ischemia.

RESUMO

Five Lactobacillus strains of intestinal and food origins were grown in MRS broth or milk containing various concentrations of linoleic acid or conjugated linoleic acid (CLA). The fatty acids had bacteriostatic, bacteriocidal, or no effect depending on bacterial strain, fatty acid concentration, fatty acid type, and growth medium. Both fatty acids displayed dose-dependent inhibition. All strains were inhibited to a greater extent by the fatty acids in broth than in milk. The CLA isomer mixture was less inhibitory than linoleic acid. Lactobacillus reuteri ATCC 55739, a strain capable of isomerizing linoleic acid to CLA, was the most inhibited strain by the presence of linoleic acid in broth or milk. In contrast, a member of the same species, L. reuteri ATCC 23272, was the least inhibited strain by linoleic acid and CLA. All strains increased membrane linoleic acid or CLA levels when grown with exogenous fatty acid. Lactobacillus reuteri ATCC 55739 had substantial CLA in the membrane when the growth medium was supplemented with linoleic acid. No association between level of fatty acid incorporation into the membrane and inhibition by that fatty acid was observed.
