Low back pain (LBP) directives provide information about how LBP should be managed, communicated and navigated in complex health systems, making them an important form of policy. This study aimed to examine how LBP is problematised (represented) in Australian directives.

We employed an analysis of discourse of LBP directives drawing on Bacchi's

policy problematisation approach.

Our analysis suggests that LBP is problematised as a symptom that tends to improve when individuals take responsibility for themselves, but may require care at times. The way in which LBP is represented in the directives excludes important aspects, such as the uncertainties of scientific knowledge, paradigms other than (post)positivist, multimorbidity, social and structural determinants of health.

LBP directives may benefit from problematisations of LBP that consider the ongoing nature of LBP and broader contextual factors that impact on both LBP outcomes and care, beyond individual responsibility. Consideration of a wider re of paradigms and expanded evidence base may also be beneficial, as these are likely to enable individuals, clinicians and the Australian healthcare system to address LBP while dealing with its complexities, enabling real-world changes to lessen the LBP burden.IMPLICATIONS FOR REHABILITATIONHealthcare professionals who work with people who experience low back pain (LBP) may benefit from critically reflecting about discourses embedded in policy directives.Healthcare professionals may consider engaging in policy changes processes to expand the discourses on which LBP policy directives rely.Healthcare professionals' ability to enact policy recommendations may be enhanced by consideration of the fluctuating nature of LBP, uncertainties, multimorbidity and determinants of health.Micro/nanomotors have emerged as a vibrant research topic in biomedical and environmental fields due to their attractive self-propulsion as well as small-scale functionalities. However, single actuated micro/nanomotors are not adaptive in facing intricate natural and industrial environments. Herein, we propose a new dual-mode-driven micromotor based on foam-like carbon nitride (f-C3N4) with precipitated Fe3O4 nanoparticles, namely, Fe3O4/f-C3N4, powered by chemical/magnetic stimuli for rapid reduction of organic pollutants. The Fe3O4/f-C3N4 motor composed of a three-dimensional (3D) porous "foam-like" structure and precipitated Fe3O4 nanoparticles (ca. 50 nm) not only exhibits efficient photocatalytic performance under visible light but also shows versatile and programmable motion behavior under the control of external magnetic fields. The aggregation of the micromotor under an external rotating magnetic field further enhances the catalytic activity by the increased local catalyst concentration. Furthermore, the magnetic property endows the micromotor with easy recyclability. This study provides a novel dual-mode-driven micromotor for antibiotics removal with magnetic field and light-enhanced performance in industrial wastewater treatment at a low cost.Huntington's disease (HD) is an inherited neurodegenerative disease. Selleck Iadademstat 3-Nitropropionic acid (3-NP) causes increased reactive oxygen species production and neuroinflammation. Centella asiatica (CA) is a strong antioxidant. The aim of this study is to investigate the effect of hydroalcoholic extract of C. asiatica (HA-CA) on 3-NP-induced HD in adult zebrafish. Adult zebrafish (∼5-6 months old) weighing 470 to 530 mg was used and treated with 3-NP (5 mg/kg intraperitoneal [i.p.]). The animals received HA-CA (80 and 100 mg/L) daily for up to 28 days in water. Tetrabenazine (3 mg/kg i.p.) was used as a standard drug. We have done an open field test (for locomotor activity), a novel tank diving test (for anxiety), and a light and dark tank test (for memory), followed by biochemical analysis (acetyl-cholinesterase [AchEs], nitrite, lipid peroxidation [LPO], and glutathione [GSH]) and histopathology to further confirm memory dysfunctions. 3-NP-treated zebrafish exhibit reductions in body weight, progressive neuronal damage, cognition, and locomotor activity. The HA-CA group significantly reduced the 3-NP-induced increase in LPO, AchEs, and nitrite levels while decreasing GSH levels. Oral administration of HA-CA (80 or 100 mg/L) significantly reduces 3-NP-induced changes in body weight and behaviors, in addition to neuroinflammation in the brain by lowering tumor necrosis factor-α and interleukin-1β levels. Moreover, HA-CA significantly decreases the 3-NP-induced neuronal damage in the brain. HA-CA ameliorates neurotoxicity and neurobehavioral deficits in 3-NP-induced HD-like symptoms in adult zebrafish.Objective The aim of this study is to report our experience in minimally invasive management of rectovesical fistulae (RVFs). Materials and Methods Between 2004 and 2021, 24 patients who underwent minimally invasive RVF repair by a single surgeon at 3 international institutions were retrospectively reviewed. Baseline demographic characteristics and perioperative and postoperative variables were collected. Complications were reported using the modified Clavien-Dindo Classification System and the European Association of Urology Complication Guidelines Panel Assessment and Recommendations. Fistula repair was defined as confirmation of fistula closure by imaging and complete resolution of fistula-related symptoms at the 12-month follow-up. Continuous variables are reported as medians and quartiles, whereas categorical variables are reported as frequencies and percentages. Results Twenty-four patients with RVFs were treated 22 males (91.7%) and 2 females with a median age of 66 (64.2-68) years. Twenty cases (83.3%) occurred postsurgery, three cases (12.5%) after surgery with combined radiotherapy, and one case (4.1%) after a combination of energy treatments. A robotic approach was performed in 19 patients (79%) and laparoscopic approach in 5 patients (21%). Ninety-six percent of patients had previous fecal diversions. No intraoperative complications were recorded. The median operative time was 180 (140-282) minutes, estimated blood loss was 50 (40-125) mL, and length of hospital stay was 2 (2-3) days. There were two Grade II complications and one Grade IIIb complication. All patients met criteria for repair. Conclusions Minimally invasive management of RVFs is feasible. More studies are needed to assess the role of this approach among all RVF management options.To the editors of the Journal of Endourology, we write to express our reservations in the recent announcement that starting in 2023 all reporting of stone-free rates be based on CT.The objective is to produce a critical-reflexivity analysis of nursing care, from the perspective of complexity thinking and social entrepreneurship. Theoretical-reflective study, supported by the framework of complexity thinking and social entrepreneurship. The main characteristics that lead and support nursing care are analyzed from a systemic-entrepreneurial perspective. A parallel is conceived between vertical care, design from a hierarchical structure and nursing care in the systemic-entrepreneurial perspective, which leads to singularity, originality, circularity, complementarity and interactivity. The centrality of nursing care is reaffirmed as a tangible social good or not. Theoretical reflection on nursing care as a systemic and entrepreneurial phenomenon raises a unique and multidimensional perception of the human being/user, health, the nursing work process, in order to achieve an increasingly agile, dynamic, circular, complementary and interdependent care.

To check adherence to the Central Venous Catheter maintenance bundle in an Intensive Care Unit, after an educational intervention to the professionals who provide care to patients using this catheter.

Descriptive-exploratory study, carried out in two stages stage 1 - educational intervention and stage 2 - verification/observation of adherence. Data were organized in the Microsoft Excel® and analyzed through the Stata®.

Sixty three workers participated in stage 1 and 44 in stage 2. The sample consisted of 64 observation opportunities. Among the domains observed, the recording of indication of permanence had an 8% compliance rate; aseptic technique in catheter handling, 3%; maintenance of the infusion system, 15%; and care with the central venous catheter dressing, 17%. The domains represent unwanted care according to the Positivity Index for assessing the quality of care.

The findings show the need for discussions, training, and investments in constant strategies for the prevention of primary bloodstream infections related to the central venous catheter.

The instability of seed yield is an urgent problem to be solved. The biological characteristics related to seed setting in larch are different from those in angiosperms and other gymnosperms. Studying the developmental mechanism of the larch sporophyll can deepen our understanding of conifer reproductive development and help to ensure an adequate supply of seeds in the seed orchard. The results showed that the formation of microstrobilus primordia in hybrid larch could be observed in anatomical sections collected in the middle of July. The contents of endogenous gibberellin 3 (GA3) and abscisic acid (ABA) were higher and the contents of GA4, GA7, jasmonic acid and salicylic acid were lower in multiseeded larch. Transcriptome analysis showed that transcription factors were significantly enriched in the AP2 family. There were 23 differentially expressed genes in the buds of the multiseeded and less-seeded types, and the expression of most of these genes was higher in the buds than in the needles. We conclude that mid-July is the early stage of reproductive organ development in hybrid larch and is suitable for the study of reproductive development. GA3 and ABA may be helpful for improving seed setting in larch, and 23 AP2/EREBP family genes are involved in the regulation of reproductive development in larch.Rod and cone photoreceptors in the retina mediate dim light and day light vision, respectively. Despite their distinctive functions, rod and cone visual pigments utilize the same vitamin A-derived chromophore. To sustain vision, vitamin A precursors must be acquired in the gut, metabolized, and distributed to the eyes. Deficiencies in this pathway in inherited ocular disease states deplete cone photoreceptors from chromophore and eventually lead to cell death, whereas the more abundant rod photoreceptors are less affected. However, pathways that support cone function and survival under such conditions are largely unknown. Using biochemical, histological, and physiological approaches, we herein show that intervention with β-carotene in STRA6-deficient mice improved chromophore supply to cone photoreceptors. Relieving the inherent negative feedback regulation of β-carotene-oxygenase-1 activity in the intestine by genetic means further bolstered cone photoreceptor functioning in the STRA6-deficient eyes. A vitamin A-rich diet, however, did not improve cone photoreceptor function in STRA6-deficiency.
