BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

Hepatitis caused by hepatitis B and C virus is increasingly becoming a significant global health threat, with widespread prevalence that may have severe disease and economic impacts in the future. Yet, preventative measures are not implemented universally and high costs of medicines limits treatment efforts. The global response to HIV/AIDS faced similar issues, but overcame them through a global movement that brought attention to the crisis and ultimately resulted in the creation and implementation of and access to better tools for HIV prevention and treatment...

BACKGROUND: Early mobility within the ICU is associated with a number of positive outcomes including reductions in ICU and hospital length of stay and better functional recovery. The exact definition of 'early' mobility is still not defined, with the actual ability to mobilise limited by a number of perceived factors. The Sara Combilizer is a combined tilt table and stretcher chair, which allows passive transfer of patients out of bed. This study aimed to assess whether the introduction of the Sara Combilizer reduced time taken to first mobilise for patients mechanically ventilated for at least five days and at risk of ICU acquired weakness...

Prevention of obesity in women of reproductive age is widely recognised to be important both for their health and for that of their offspring. Weight-control interventions, including drug treatment, in pregnant women who are obese or overweight have not had sufficient impact on pregnancy and birth outcomes, which suggests that the focus for intervention should include preconception or post-partum periods. Further research is needed into the long-term effects of nutritional and lifestyle interventions before conception...

Transient receptor potential melastatin subfamily 3 (TRPM3) ion channels play a role in calcium (Ca(2+) ) cell signalling. Reduced TRPM3 has been identified in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) patients. However, the significance of TRPM3 and association with intracellular Ca(2+) mobilisation has yet to be determined. Fifteen CFS/ME patients (mean age 48.82 ± 9.83 years) and 25 health controls (mean age 39.2 ± 12.12 years) were examined. Isolated NK cells were labelled with fluorescent antibodies to determine TRPM3, CD107a, and CD69 receptors on CD56(Dim) CD16(+) NK cells and CD56(Bright) CD16(Dim/-) NK cells...

BACKGROUND: Adventitious root (AR) formation in axillary shoot tip cuttings is a crucial physiological process for ornamental propagation that is utilised in global production chains for young plants. In this process, the nitrogen and carbohydrate metabolisms of a cutting are regulated by its total nitrogen content (Nt), dark exposure during transport and irradiance levels at distinct production sites and phases through a specific plasticity to readjust metabolite pools. Here, we examined how elevated Nt contents with a combined dark exposure of cuttings influence their internal N-pools including free amino acids and considered early anatomic events of AR formation as well as further root development in Petunia hybrida cuttings...

Beach environments are known to be conducive to fragmentation of plastic debris, and highly fragmented plastic particles can interact with smaller organisms. Even through stranded plastic debris may not interact directly with marine organisms, backwash processes may transport this debris back to coastal waters, where it may affect a wide range of marine life at different trophic levels. This study analysed the size distribution of stranded plastic debris (<10 mm) collected from eight coastal beaches in Guangdong Province, China...

BACKGROUND: NHS England's Five Year Forward View (NHS England, Five Year Forward View, 2014) formally introduced a strategy for new models of care driven by simultaneous pressures to contain costs, improve care and deliver services closer to home through integrated models. This synthesis focuses on a multispecialty community provider (MCP) model. This new model of care seeks to overcome the limitations in current models of care, often based around single condition-focused pathways, in contrast to patient-focused delivery (Royal College of General Practitioners, The 2022 GP: compendium of evidence, 2012) which offers greater continuity of care in recognition of complex needs and multimorbidity...

BACKGROUND: To analyse the effect of real-time kinematic feedback (KRTF) when learning two ankle joint mobilisation techniques comparing the results with the traditional teaching method. METHODS: Double-blind randomized trial. SETTINGS: Faculty of Health Sciences. PARTICIPANTS: undergraduate students with no experience in manual therapy. Each student practised intensely for 90 min (45 min for each mobilisation) according to the random methodology assigned (G1: traditional method group and G2: KRTF group)...

BACKGROUND: Immobilisation predicts adverse outcomes in patients in the surgical intensive care unit (SICU). Attempts to mobilise critically ill patients early after surgery are frequently restricted, but we tested whether early mobilisation leads to improved mobility, decreased SICU length of stay, and increased functional independence of patients at hospital discharge. METHODS: We did a multicentre, international, parallel-group, assessor-blinded, randomised controlled trial in SICUs of five university hospitals in Austria (n=1), Germany (n=1), and the USA (n=3)...

BACKGROUND: The majority of clinical trials regarding post-operative pain treatment focuses on the average analgesic efficacy, rather than on efficacy in individual patients. It has been argued, that in acute pain trials, the underlying distributions are often skewed, which makes the average unfit as the only way to measure efficacy. Consequently, dichotomised, individual responder analyses using a predefined 'favourable' response, e.g. Visual Analogue Scale (VAS) pain scores ≤ 30, have recently been suggested as a more clinical relevant outcome...

Walking groups have known health benefits but may not operate in communities with the greatest health needs, leading to the potential for increasing health inequity. This study examined the process of implementing a new volunteer led walking group scheme in a deprived community in England with poor physical activity, health and socio-economic indicators. Documentary evidence and semi-structured interviews with stakeholders and volunteer walk leaders undertaken at the beginning and end of the funding period were analysed thematically...

The present study investigated whether changes of energy metabolism post-partum (pp) are associated with claw health. For this purpose, back-fat-thickness (BFT) was measured and blood samples were taken from 146 cows at four examination times. The serum levels of free fatty acids (FFA), ß-hydroxybutyrate (BHB) and glucose were measured. Furthermore, in the first week postpartum (pp) and at 8 weeks pp, a claw trimming was done and the presence and extent of sole haemorrhages (SH) was recorded. Animals with high BFT at calving and therefore high fat mobilisation and whose FFA and BHB levels in the first week pp exceeded the reference values had fewer pathological changes of the claws than thinner animals whose FFA and BHB levels stayed within reference ranges...

The lumen of the fish intestine is a complex and dynamic environment. In order to understand the conditions affecting bioavailability and toxicity of citrate coated silver nanoparticles (cit-AgNP) and dissolved silver at the luminal enterocyte interface, we exposed rainbow trout (Oncorhynchus mykiss) gut cells (RTgutGC) in media of contrasting composition: two protein and/or amino acid containing media as can be expected during digestion, and two protein-/amino acid-free media contrasting a low and a high chloride content as can be expected in the lumen of fish adapting to freshwater or seawater, respectively...

There is now a growing body of research indicating that prevention interventions can reduce intimate partner violence (IPV); much less is known, however, about how couples exposed to these interventions experience the change process, particularly in low-income countries. Understanding the dynamic process that brings about the cessation of IPV is essential for understanding how interventions work (or don't) to reduce IPV. This study aimed to provide a better understanding of how couples' involvement with SASA!-a violence against women and HIV-related community mobilisation intervention developed by Raising Voices in Uganda-influenced processes of change in relationships...

The purpose of the research was to determine whether an HIV stigma-reduction community "hub" network intervention in a South African urban area would bring about a difference in the psychosocial well-being of people living with HIV (PLWH), as well as their community (living in the same municipal ward). A single case pre-test post-test design was implemented. The sample for this study included 62 PLWH who were selected through accessibility sampling and 570 community members who were selected through random voluntary sampling...

PURPOSE: Enhanced recovery after surgery (ERAS) pathways are standard practice in adult specialties resulting in improved outcomes. It is unclear whether ERAS principles are applicable to Paediatric Surgery. We performed a scoping review to identify the extent to which ERAS has been used in Paediatric Surgery, the nature of interventions, and outcomes. METHODS: Pubmed, Cochrane library, Google Scholar, and Embase were searched using the terms enhanced recovery, post-operative protocol/pathway, fast track surgery, and paediatric surgery...

AIMS/HYPOTHESIS: To directly assess the role of beta cell lipolysis in insulin secretion and whole-body energy homeostasis, inducible beta cell-specific adipose triglyceride lipase (ATGL)-deficient (B-Atgl-KO) mice were studied under normal diet (ND) and high-fat diet (HFD) conditions. METHODS: Atgl (flox/flox) mice were cross-bred with Mip-Cre-ERT mice to generate Mip-Cre-ERT(/+);Atgl (flox/flox) mice. At 8 weeks of age, these mice were injected with tamoxifen to induce deletion of beta cell-specific Atgl (also known as Pnpla2), and the mice were fed an ND or HFD...
