Abstract
Improvements in cancer care have led to an exponential increase in cancer survival. This is particularly the case for breast cancer, where 5-year survival in Australia exceeds 90%. Cardiovascular disease (CVD) has emerged as one of the competing causes of morbidity and mortality among cancer survivors, both as a complication of cancer therapies and because the risk factors for cancer are shared with those for CVD. In this review we cover the key aspects of cardiovascular care for women throughout their cancer journey: the need for baseline cardiovascular risk assessment and management, a crucial component of the cardiovascular care; the importance of long-term surveillance for ongoing maintenance of cardiovascular health; and strong evidence for the beneficial effects of physical exercise to improve both cancer and cardiovascular outcomes. There is general disparity in cardiovascular outcomes for women, which is further exacerbated when both CVD and cancer co-exist. Collaboration between oncology and cardiac services, with an emergence of the whole field of cardio-oncology, allows for expedited investigation and treatment for these patients. This collaboration as well as a holistic approach to patient care and key role of patients' general practitioners are essential to ensure long-term health of people living with, during and beyond cancer.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Control over supramolecular recognition between proteins and nanoparticles (NPs) is of fundamental importance in therapeutic applications and sensor development. Most NP-protein binding approaches use 'tags' such as biotin or His-tags to provide high affinity; protein surface recognition provides a versatile alternative strategy. Generating high affinity NP-protein interactions is challenging however, due to dielectric screening at physiological ionic strengths. We report here the co-engineering of nanoparticles and protein to provide high affinity binding. In this strategy, 'supercharged' proteins provide enhanced interfacial electrostatic interactions with complementarily charged nanoparticles, generating high affinity complexes. Significantly, the co-engineered protein-nanoparticle assemblies feature high binding affinity even at physiologically relevant ionic strength conditions. Computational studies identify both hydrophobic and electrostatic interactions as drivers for these high affinity NP-protein complexes.

Abstract
Covalent linkage between the single-walled carbon nanotube (SWCNT) and CYP101 through a specific site of the enzyme can provide a novel method of designing efficient enzyme electrodes using this prototype cytochrome P450 enzyme. We have chemically modified the SWCNT with linker 4-carboxy phenyl maleimide (CPMI) containing maleimide functional groups. The enzyme was covalently attached on to the SWCNT through the maleimide group of the linker (CPMI) to the thiolate group of the surface exposed Cys 58 or Cys 136 of the CYP101 forming a covalently immobilized protein on the nanotube. Thin film of the modified SWCNT-CPMI-CYP101conjugate was made on a glassy carbon (GC) electrode. Direct electrochemistry of the substrate (camphor)-bound enzyme was studied using this immobilized enzyme electrode system and the redox potential was found to be -320mV vs Ag/AgCl (3 M KCl), which agrees with the redox potential of the substrate bound enzyme reported earlier. The electrochemically driven enzymatic mono-oxygenation of camphor by this immobilized enzyme electrode system was studied by measurement of the catalytic current at different concentrations of camphor. The catalytic current was found to increase with increasing concentration of camphor in presence of oxygen. The product formed during the catalysis was identified by mass-spectrometry as hydroxy-camphor.

Abstract
Macrophages are key effectors of host defense and metabolism, making them promising targets for transient genetic therapy. Gene editing through delivery of the Cas9-ribonucleoprotein (RNP) provides multiple advantages over gene delivery-based strategies for introducing CRISPR machinery to the cell. There are, however, significant physiological, cellular, and intracellular barriers to the effective delivery of the Cas9 protein and guide RNA (sgRNA) that have to date, restricted in vivo Cas9 protein-based approaches to local/topical delivery applications. Herein we describe a new nanoassembled platform featuring co-engineered nanoparticles and Cas9 protein that has been developed to provide efficient Cas9-sgRNA delivery and concomitant CRISPR editing through systemic tail-vein injection into mice, achieving >8% gene editing efficiency in macrophages of the liver and spleen.

Abstract
Introduction There is relatively little data on the preparedness of UK dental graduates for independent general dental practice. Two recent studies have indicated that graduates appear well prepared, but although quantifying the level of preparedness, they provide limited understanding of the underlying factors contributing to preparedness. This study aims to more deeply understand the contributing factors leading to assertions of graduate preparedness using focus groups of final year dental students, and semi-structured interviews of senior faculty members. Materials and methods Three UK dental schools were visited in order to conduct both study elements. Focus groups and semi-structured interviews were audio recorded and fully transcribed. Thematic analysis of the transcripts resulted in the production of a thematic matrix. Results The major categories of the thematic matrix were classified as extrinsic; including the role of educators and features of the course, and intrinsic; relating to fear of the unknown, the development of adult learning abilities and less easily identifiable attributes in the development of competence, which became known as 'bricks and mortar'. Discussion Students felt that the most important factor affecting their preparation was clinical exposure. Outreach placements were felt to be particularly useful, the simulation of general dental practice being highly valued by final year students. The interaction with educators was also felt to be a key influence on preparedness, with the involvement of general practitioners in dental school teaching felt to be helpful, perhaps giving students an extended exposure to general practice. Conclusion It is hoped that the rich data derived from this study may allow an invaluable insight into factors contributing to preparedness of new dental graduates, which may then be considered in the light of any proposed changes in the curricula or syllabi.

Abstract
The delivery of proteins into cells is a potential game changer for a wide array of therapeutic purposes, including cancer therapy, immunomodulation and treatment of inherited diseases. In this review, we present recently developed nanoassemblies for protein delivery that utilize strategies that range from direct assembly, encapsulation and composite formation. We will discuss factors that affect the efficacy of nanoassemblies for delivery from the perspective of both nanoparticles and proteins. Challenges in the field, particularly achieving effective cytosolar protein delivery through endosomal escape or evasion are discussed.

Abstract
Polymeric supramolecular assemblies that can effectively transport proteins across an incompatible solvent interface are described. We show that electrostatics and ligand-protein interactions can be used to selectively transport proteins from an aqueous phase to organic phase. These transported proteins have been shown to maintain their tertiary structure and function. This approach opens up new possibilities for application of supramolecular assemblies in sensing, diagnostics and catalysis.

Abstract
Obesity is highly correlated with the dysbiosis of intestinal microbiota, and bifidobacteria are one of the soft targets of this metabolic syndrome. The aim of this study is to evaluate the efficacy of Bifidobacterium sp. MKK4 and rice-based fermented foods on physical, haematological, gut microbiota and lypogenic-lypolytic marker genes in diet-induced obese mice. Adult male mice (21±0.7 g) were randomly divided into four groups (n=10) according to the type of diet: normal diet (ND), high fat diet (HFD), HFD supplemented with Bifidobacterium sp. MKK4 and HFD supplemented with MKK4 associated rice-fermented food. 8 weeks of bacterial therapy in the obese mice resulted in significant reduction of body and organ weights, improved serum levels of glucose, triglyceride and cholesterol, the histological structure of the liver (steatosis), and re-establishment of gut Lactobacillus, Bifidobacterium and Bacteroides species. The bacterial therapy led to up-regulation of lipolytic transcription factors, such as peroxisome proliferator-activated receptor (PPAR)-α, PPAR-δ, and their regulated gene products in fatty acid metabolism and glucose uptake, such as acyl-CoA oxidase, carnitine palmitoyl-transferase-1, uncoupling protein-3 and glucose transporter-4. Concomitantly, both adipocytogenesis and fatty acid synthesis were arrested as reflected by the down-regulation of sterol regulatory element binding protein-1c, acetyl-CoA carboxylase, fatty acid synthase and tumour necrosis factor alpha genes. The effectiveness of the fermented product was more profound than the single bacterium. These data provide experimental support with regard to the use of Bifidobacterium sp. MKK4 as a natural therapeutic agent to control obesity.

Abstract
We present here an integrated nanotechnology/biology strategy for cancer immunotherapy that uses arginine nanoparticles (ArgNPs) to deliver CRISPR-Cas9 gene editing machinery into cells to generate SIRP-α knockout macrophages. The NP system efficiently codelivers single guide RNA (sgRNA) and Cas9 protein required for editing to knock out the "don't eat me signal" in macrophages that prevents phagocytosis of cancer cells. Turning off this signal increased the innate phagocytic capabilities of the macrophages by 4-fold. This improved attack and elimination of cancer cells makes this strategy promising for the creation of "weaponized" macrophages for cancer immunotherapy.

Abstract
Endosomal entrapment is a key hurdle for most intracellular protein-based therapeutic strategies. We report a general strategy for efficient delivery of proteins to the cytosol through co-engineering of proteins and nanoparticle vehicles. The proteins feature an oligo(glutamate) sequence (E-tag) that binds arginine-functionalized gold nanoparticles, generating hierarchical spherical nanoassemblies. These assemblies fuse with cell membranes, releasing the E-tagged protein directly into the cytosol. Five different proteins with diverse charges, sizes, and functions were effectively delivered into cells, demonstrating the generality of our method. Significantly, the engineered proteins retained activity after cytosolic delivery, as demonstrated through the delivery of active Cre recombinase, and granzyme A to kill cancer cells.

Abstract
Active intracellular transport is a central mechanism in cell biology, directed by a limited set of naturally occurring signaling peptides. Here, we report the first nonpeptide moiety that recruits intracellular transport machinery for nuclear targeting. Proteins synthetically modified with a simple aromatic boronate motif are actively trafficked to the nucleus via the importin α/β pathway. Significantly, proteins too large to passively diffuse through nuclear pores were readily imported into the nucleus through this boronate-mediated pathway. The use of this simple motif to provide active intracellular targeting provides a promising strategy for directing subcellular localization for therapeutic and fundamental applications.

Abstract
Hierarchical organization of macromolecules through self-assembly is a prominent feature in biological systems. Synthetic fabrication of such structures provides materials with emergent functions. Here, we report the fabrication of self-assembled superstructures through coengineering of recombinant proteins and nanoparticles. These structures feature a highly sophisticated level of multilayered hierarchical organization of the components: individual proteins and nanoparticles coassemble to form discrete assemblies that collapse to form granules, which then further self-organize to generate superstructures with sizes of hundreds of nanometers. The components within these superstructures are dynamic and spatially reorganize in response to environmental influences. The precise control over the molecular organization of building blocks imparted by this protein-nanoparticle coengineering strategy provides a method for creating hierarchical hybrid materials.
