Fractionated stereotactic radiotherapy of intracranial postoperative cavities after resection of brain metastases - Clinical outcome and prognostic factors. Clin Transl Radiat Oncol 2024; 46:100782. [PMID: 38694237 PMCID: PMC11061678 DOI: 10.1016/j.ctro.2024.100782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 04/17/2024] [Accepted: 04/20/2024] [Indexed: 05/04/2024] Open
Abstract
Background and Purpose After surgical resection of brain metastases (BM), radiotherapy (RT) is indicated. Postoperative stereotactic radiosurgery (SRS) reduces the risk of local progression and neurocognitive decline compared to whole brain radiotherapy (WBRT). Aside from the optimal dose and fractionation, little is known about the combination of systemic therapy and postoperative fractionated stereotactic radiotherapy (fSRT), especially regarding tumour control and toxicity. Methods In this study, 105 patients receiving postoperative fSRT with 35 Gy in 7 fractions performed with Cyberknife were retrospectively reviewed. Overall survival (OS), local control (LC) and total intracranial brain control (TIBC) were analysed via Kaplan-Meier method. Cox proportional hazards models were used to identify prognostic factors. Results Median follow-up was 20.8 months. One-year TIBC was 61.6% and one-year LC was 98.6%. Median OS was 28.7 (95%-CI: 16.9-40.5) months. In total, local progression (median time not reached) occurred in 2.0% and in 20.4% radiation-induced contrast enhancements (RICE) of the cavity (after median of 14.3 months) were diagnosed. Absence of extracranial metastases was identified as an independent prognostic factor for superior OS (p = <0.001) in multivariate analyses, while a higher Karnofsky performance score (KPS) was predictive for longer OS in univariate analysis (p = 0.041). Leptomeningeal disease (LMD) developed in 13% of patients. Conclusion FSRT after surgical resection of BM is an effective and safe treatment approach with excellent local control and acceptable toxicity. Further prospective randomized trials are needed to establish standardized therapeutic guidelines.

Functional outcomes following anterior resection for colorectal cancer: a needs assessment and proposal of a nurse-led remote management algorithm. ANZ J Surg 2024. [PMID: 38680012 DOI: 10.1111/ans.19010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 04/05/2024] [Accepted: 04/09/2024] [Indexed: 05/01/2024]
Abstract
AIM With the rise of structured, remote follow-up of colorectal cancers, there is the potential risk of underdiagnosing and undermanaging low anterior resection syndrome (LARS). This cohort study aims to determine the rate of LARS and its patterns of care, with the aim of generating a risk-stratified management algorithm that can be employed for nurse-led follow-up. METHOD Patients who underwent elective anterior resection for the management of colorectal cancer between 1 January 2017 and 31 December 2021 were sent quality-of-life questionnaires (EORTC-QLQ-CR29 and LARS score) and surveyed for LARS symptoms and management utilized. RESULTS Out of 70 patients who completed questionnaires, 71.4% had LARS and 42.9% had major LARS. The international Delphi consensus definition identified more patients (n = 50) with LARS than the LARS score (n = 41). Tumours located <8 cm from the anal verge, ULAR, and temporary stoma were predictive of major LARS on univariate analysis. However, only temporary stoma was predictive for LARS (OR 7.89 (1.15-53.95), P = 0.035) and majors LARS (8.14 (1.79-37.01), P = 0.007) on multivariate analysis. Forty-four percent of patients with LARS did not have input from any health professional for this condition. Consultation with specialist allied health and/or colorectal surgeons ranged from 4% to 22%. CONCLUSIONS Our study highlights that with the current remote follow-up system focused on cancer outcomes a significant proportion of patients with LARS are overlooked, resulting in the underutilization of relevant health professionals and management options. We propose a nurse-led management algorithm to address this issue while still minimizing surgical outpatient load.

Psychological factors and long-term tinnitus handicap in vestibular schwannoma patients after retrosigmoid microsurgery - a cross-sectional study. Int J Audiol 2024:1-8. [PMID: 38613519 DOI: 10.1080/14992027.2024.2339351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 04/01/2024] [Indexed: 04/15/2024]
Abstract
OBJECTIVE This study aimed to investigate the connection between psychological factors and postoperative tinnitus in vestibular schwannoma (VS) patients following retrosigmoid microsurgery. DESIGN Cross-sectional study. STUDY SAMPLE Ninety-three VS patients participated, completing questionnaires on demographics, tinnitus severity (THI-12), personality traits (TIPI-G), dizziness impact (DHI), perceived health benefits (GBI), somatisation tendencies (SOMS-2), and psychological distress (HADS-D). Our analysis involved Mann-Whitney U-tests, Spearman's rank-order correlations, and false discovery rate correction. RESULTS Most participants reported postoperative tinnitus (77/93), with 41 experiencing it preoperatively. Emotional stability correlated negatively with tinnitus presence, while tinnitus severity was associated with emotional distress. Preoperative somatisation tendencies were also positively linked to tinnitus severity. Postoperative Tinnitus was further linked to reduced perceived health benefits and increased anxiety and depression levels. Notably, age and gender showed no significant associations. CONCLUSION This study uncovers the interplay between postoperative tinnitus and psychological factors in VS patients, highlighting emotional and cognitive dimensions. Tailored psychological interventions addressing tinnitus's psychosomatic impact may enhance patients quality of life.

American Indian and Alaska Native violence prevention efforts: a systematic review, 1980 to 2018. Inj Epidemiol 2024; 8:72. [PMID: 38504377 PMCID: PMC10949553 DOI: 10.1186/s40621-024-00488-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/07/2024] [Indexed: 03/21/2024] Open
Abstract
BACKGROUND Violence is a serious public health concern disproportionately experienced by American Indian and Alaska Native (AIAN) people. While the burden and impact of violence may be explained by the presence of risk factors among this group, AIAN communities benefit from unique protective factors and universal strategies which may be tailored with tribal adaptations. We sought to identify and explore violence prevention strategies specific to AIAN populations. METHODS A review was conducted to systematically identify violence prevention programs, policies, and practices implemented in AIAN communities. We searched nine electronic databases and relevant gray literature released between January 1980 and June 2018. We included intervention-focused records targeting at least one violence topic area (child abuse/neglect, elder abuse, intimate partner violence, sexual violence, youth violence, and suicide) in a majority (> 50%) AIAN population. RESULTS A total of 5220 non-duplicate records were screened, yielding 318 full-text records. After applying exclusion criteria, 57 records describing 60 program, policy, or practice implementations of 43 unique interventions were identified. All six violence types were represented, although more than half (58%; n = 25/43) focused on suicide prevention. Among suicide prevention programs, the most common strategies were identifying and supporting people at risk (80%; n = 20), teaching coping and problem-solving skills (56%; n = 14), and promoting connectedness (48%; n = 12). Two-thirds of the implementations (67%; n = 40/60) were in fully (100%) AIAN communities. Programs were implemented across many settings, though schools were the most common (35%, n = 21/60) setting. Of the 60 total implementations, a majority (80%; n = 48) were new approaches developed by and for AIAN communities, while the remainder were AIAN adaptations of programs previously created for non-AIAN populations. Most implementations (60%; n = 36/60) provided some evaluation data although less than half (45%; n = 27/60) reported evaluation results. CONCLUSIONS This review identified many violence prevention strategies specific to AIAN populations. While programs developed in one tribe may not be completely generalizable to others, shared tribal risk and protective factors suggest programs could be successful across diverse communities. Findings indicate there is a need to develop and evaluate violence prevention programs, policies and practices for AIAN populations.

A systematic review of the use of the concept family resilience in interventions with families with children and young people. Public Health Nurs 2024; 41:346-355. [PMID: 38284476 DOI: 10.1111/phn.13287] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 12/17/2023] [Accepted: 01/11/2024] [Indexed: 01/30/2024]
Abstract
OBJECTIVE To review the evidence on using family resilience as a concept in interventions by public health nurses/health visitors with families with children and young people as part of an evaluation of the evidence base for the Family Resilience Assessment Instrument and Tool (FRAIT). FRAIT was developed by University faculty with Health Visitors and a Community of Practice in Wales, and is used by Health Visitors in Wales with families with children under 5 years to assess family resilience. METHOD A standard Cochrane Systematic Review methodology was used to review published literature. A protocol (crd.york.ac.uk/PROSPERO/display_record.php?RecordID = 230845) was submitted to Prospero in September 2021, and reviewing began in January 2022. Title and abstract searching were undertaken 12 databases and results were captured using PRISMA and Excel spreadsheet. Second reviewers reviewed title and abstract screening, and full-text extraction. RESULTS Initial title screening brought back 1350 papers across 12 databases. Titles and abstract screening reduced these to 106, 44 papers were considered for full-text extraction, with 25 papers included for review. DISCUSSION Results demonstrated a focus on specific demographics, and use of family resilience with families living with specific health problems. Existing family resilience scales showed improved results in selected specific demographic groups, albeit in a reactive way. FRAIT has originality within the literature as it is used in a universal, preventative way with all families regardless of demographic or health issues. There is evidence to show that using a family resilience program in this way has originality and implications for the physical and mental health of children and young people. NO PATIENT OR PUBLIC CONTRIBUTION This was a systematic review of existing literature so public or patient contribution would not have been appropriate.

Abstract
In electron diffraction, thermal atomic motion produces incoherent scattering over a relatively wide angular range, which appears as a diffuse background that is usually subtracted from measurements of Bragg spot intensities in structure solution methods. The transfer of electron flux from Bragg spots to diffuse scatter is modelled using complex scattering factors f + if' in the Bloch wave methodology. In a two-beam Einstein model the imaginary `absorptive' scattering factor f' can be obtained by the evaluation of an integral containing f over all possible scattering angles. While more sophisticated models of diffuse scatter are widely used in the electron microscopy community, it is argued in this paper that this simple model is appropriate for current structure solution and refinement methods. The two-beam model is a straightforward numerical calculation, but even this simplistic approach can become time consuming for simulations of materials with large numbers of atoms in the unit cell and/or many incident beam orientations. Here, a parameterized form of f' is provided for 103 elements as neutral, spherical atoms that reduces calculation time considerably.

Abstract
Bioengineered probiotics enable new opportunities to improve colorectal cancer (CRC) screening, prevention and treatment. Here, first, we demonstrate selective colonization of colorectal adenomas after oral delivery of probiotic E. coli Nissle 1917 (EcN) to a genetically-engineered murine model of CRC predisposition and orthotopic models of CRC. We next undertake an interventional, double-blind, dual-centre, prospective clinical trial, in which CRC patients take either placebo or EcN for two weeks prior to resection of neoplastic and adjacent normal colorectal tissue (ACTRN12619000210178). We detect enrichment of EcN in tumor samples over normal tissue from probiotic-treated patients (primary outcome of the trial). Next, we develop early CRC intervention strategies. To detect lesions, we engineer EcN to produce a small molecule, salicylate. Oral delivery of this strain results in increased levels of salicylate in the urine of adenoma-bearing mice, in comparison to healthy controls. To assess therapeutic potential, we engineer EcN to locally release a cytokine, GM-CSF, and blocking nanobodies against PD-L1 and CTLA-4 at the neoplastic site, and demonstrate that oral delivery of this strain reduces adenoma burden by ~50%. Together, these results support the use of EcN as an orally-deliverable platform to detect disease and treat CRC through the production of screening and therapeutic molecules.

Reduced fertility in an adenomyosis mouse model is associated with an altered immune profile in the uterus during the implantation period. Hum Reprod 2024; 39:119-129. [PMID: 38011900 DOI: 10.1093/humrep/dead246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 11/03/2023] [Indexed: 11/29/2023] Open
Abstract
STUDY QUESTION Does a reduction in fertility and/or systemic immune cell change occur during the early implantation period in a mouse model of adenomyosis? SUMMARY ANSWER A reduction in fertility was observed in mice with adenomyosis, coinciding with local and systemic immune changes observed during the implantation period. WHAT IS KNOWN ALREADY Adenomyosis is a pathology responsible for impaired fertility in humans, with a still unclear pathophysiology. One hypothesis is that changes in immune cells observed in adenomyosis-affected uteri may alter fertility, notably the physiological immune environment necessary for successful implantation and a healthy pregnancy. STUDY DESIGN, SIZE, DURATION Randomly selected CD-1 female neonatal pups were orally dosed by administration of tamoxifen to induce adenomyosis (TAM group), while others received solvent only (control group). From 6 weeks of life, CD-1 mice of both groups were mated to study impaired fertility and related local and/or systemic immune cell changes during the early implantation period. PARTICIPANTS/MATERIALS, SETTINGS, METHODS To evaluate fertility and pregnancy outcomes, ultrasound imaging was performed at E (embryonic day) 7.5 and E11.5 to count the number of gestational sacs and the number of resorptions in eight mice of the TAM group and 16 mice of the control group. The mice were sacrificed at E18.5, and morphometric, functional (quantitative reverse transcription PCR; RT-qPCR), and histological analyses were performed on the placentas. To identify local and/or systemic immune changes during the early implantation period, 8 mice of the TAM group and 12 mice of the control group were sacrificed at E4.5. Uterine horns and spleens were collected for flow cytometry and RT-qPCR analyses to study the immune cell populations. To investigate the profile of the cytokines secreted during the early implantation period at the systemic level, supernatants from stimulated spleen cells were analyzed by multiplex immunoassay analysis. MAIN RESULTS AND THE ROLE OF CHANCE By ultrasound imaging, we observed a lower number of implantation sites (P < 0.005) and a higher number of resorptions (P < 0.001) in the TAM group, leading to smaller litters (average number of fetuses per litter: 1.00 [0.00; 5.25] in the TAM group versus 12.00 [9.50; 13.75] in the control group (P < 0.001). Histological and morphometric analyses of the placentas at E18.5 showed a higher junctional/labyrinthine area ratio in the TAM group (P = 0.005). The expression levels of genes that play a role in vascularization and placental growth (Vegf (P < 0.001), Plgf (P < 0.005), Pecam (P < 0.0001), and Igf2 (P = 0.002)) were reduced in the TAM group. In the TAM group, the percentages of macrophages, natural killer (NK) cells, and dendritic cells (DC) were significantly decreased in the uterus around the implantation period. However, the number of M1 macrophages was increased. Both macrophages and DC had an increased activation profile (higher expression of MCHII, P = 0.012; CD80, P = 0.015; CCR7, P = 0.043 for macrophages, and higher expression of CD206, P = 0.018; CXCR4, P = 0.010; CCR7, P = 0.006, MCHII, P = 0.010; and CD80, P = 0.012 for DC). In spleen, an increase in the activation of macrophages (CCR7, P = 0.002; MCHII, P = 0.001; and CD80, P = 0.034) and DC was observed in the TAM group (CCR7, P = 0.001; MCHII, P = 0.001; Ly6C, P = 0.015). In the uteri and the spleen, we observed increased percentages of CD4+ T lymphocytes (P = 0.0237 and P = 0.0136, respectively) in the TAM group and, in the uteri, an increased number of regulatory T cells (P = 0.036) compared with the controls. LARGE SCALE DATA Not applicable. LIMITATIONS, REASONS FOR CAUTION This study is limited by the use of an animal model and the lack of intervention. WIDER IMPLICATIONS OF THE FINDINGS These data support involvement of innate and adaptive immune cells in the implantation failure and the increased rate of resorption observed in the mouse model of adenomyosis. This substantiates the need for additional research in this domain, with the goal of addressing fertility challenges in women affected by this condition. STUDY FUNDING/COMPETING INTEREST(S) None.

Abstract
PURPOSE To analyse multiparametric magnetic resonance imaging (mpMRI) characteristics and appearance of histopathologically proven non-cancerous intraprostatic findings focussing on quantity of prostatitis and atrophy in the peripheral zone. METHOD In this retrospective analysis consecutive patients with mpMRI followed by MRI/TRUS-fusion biopsy comprising targeted (TB) and systematic biopsy (SB) cores without prostate cancer (PC) at histopathology were included. Subgroup analysis was performed in younger men (≤50 years). The proportions of prostatitis and atrophy were quantified for each biopsy core based on histopathology. MRI findings in the peripheral zone (PZ) and index lesions (IL, most suspicious/representative lesion) were characterized regarding changes in T2w, ADC value, and enhancement of dynamic contrast enhancement (DCE) and correlated with quantity of prostatitis and atrophy. RESULTS Seventy-two patients were analysed. The median baseline characteristics were PSA 5.4 ng/ml (4.0-7.9), PI-RADS classification 3 (2-4), prostate volume 43 ml (33-57), and PSA density 0.13 ng/ml2 (0.10-0.19). Prostatitis was found in 44 % (n = 32) and atrophy in 65 % (n = 47) of cases. The quantity of atrophy demonstrated a significant correlation to T2w changes, ADC increase and DCE enhancement (p = 0.05, p = 0.05, p = 0.01), whereas quantity of prostatitis did not show any significant correlation to the MRI changes (p = 0.68, p = 0.58, p = 0.95). Quantity of prostatitis and atrophy increased with PI-RADS classification. Younger men had lower PSA (4.4 vs. 7.8 ml/ng; p < 0.001), smaller prostate volume (40 vs. 59 ml; p = 0.001), and lower PI-RADS classification (2-3 vs. 3-4; p = 0.005) and prostatitis and atrophy were less frequently observed (p ≤ 0.01, p = 0.03). CONCLUSIONS Quantity of atrophy and prostatitis had different influence on MRI characteristics and increased within higher PI-RADS classification. Younger men had diffuse hypointense changes at T2w images, but less quantity of prostatitis and atrophy.

Abstract
BACKGROUND Lymphoedema is a chronic condition affecting daily activities of life, causing significant alterations and adjustments. Since 2015, lymphaticovenous anastomosis (LVA) has been available on the National Health Service for people with lymphoedema in Wales, United Kingdom. This study aimed to explore the impact and outcomes after LVA over a 24-month follow-up. METHODS Data were prospectively captured before and after LVA surgery on 150 patients with unilateral upper or lower limb lymphoedema. The same team (three lymphoedema specialists and two plastic surgeons) assessed/operated on all patients. Data captured included a quality of life tool (EQ5D5L), circumferential measurements (tape measure/perometer), compression garment usage, occurrence of cellulitis and a range of patient-reported outcome measures. RESULTS People who underwent LVA surgery had predominantly cancer-related lymphoedema (n = 118). Reviewing baseline data and 24-months after LVA, quality of life statistically improved (p = <0.005), as well as pain, heaviness, anxiety, impact on hobbies, work, purchasing clothes and intimacy/desirability. Mean perometer and circumferential measurements did not reduce over the 24 months. Number of days per week and hours that the patient wore compression garments did lessen and was statistically significant (p = <0.001). The quantity of cellulitis episodes captured from two years before and two years after LVA decreased from 4.22 to 0.10 (p = <0.001). Significant results (p = <0.001) were also found in a reduction in patients taking days off work due to cellulitis (5.81 to 0.16). CONCLUSION LVA resulted in significant improvements in patient-reported outcome measures, cellulitis episodes and reduced need for compression garments. Limb circumference via tape measure/perometer did not alter, yet the patient's quality of life considerably improved.

The development of the relationship between auditory and visual neural sensitivity and autonomic arousal from 6 m to 12 m. Dev Cogn Neurosci 2023; 63:101289. [PMID: 37597447 PMCID: PMC10458697 DOI: 10.1016/j.dcn.2023.101289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 08/03/2023] [Accepted: 08/08/2023] [Indexed: 08/21/2023] Open
Abstract
The differential sensitivity hypothesis argues that environmental sensitivity has the bivalent effect of predisposing individuals to both the risk-inducing and development-enhancing influences of early social environments. However, the hypothesis requires that this variation in environmental sensitivity be general across domains. In this study, we focused on neural sensitivity and autonomic arousal to test domain generality. Neural sensitivity can be assessed by correlating measures of perceptual sensitivity, as indexed by event-related potentials (ERP) in electrophysiology. The sensitivity of autonomic arousal can be tested via heart rate changes. Domain generality was tested by comparing associations in perceptual sensitivity across auditory and visual domains, and associations between sensitivity in sensory domains and heart rate. We contrasted ERP components in auditory (P3) and visual (P1, N290 and P4) detection-of-difference tasks for N = 68 infants longitudinally at 6 and 12 months of age. Domain generality should produce correlated individual differences in sensitivity across the two modalities, with higher levels of autonomic arousal associating with increased perceptual sensitivity. Having controlled for multiple comparisons, at 6 months of age, the difference in amplitude of the P3 component evoked in response to standard and deviant tones correlated with the difference in amplitude of the P1 N290 and P4 face-sensitive components evoked in response to fearful and neutral faces. However, this correlation was not found at 12 months of age. Similarly, autonomic arousal correlated with neural sensitivity at 6 months but not at 12 months. The results suggest bottom-up neural perceptual sensitivity is domain-general across auditory and visual domains and is related to autonomic arousal at 6 months but not at 12 months of age. We interpret the development of the association of these markers of ES within a neuroconstructivist framework and with respect to the concept of interactive specialisation. By 12 months of age, more experience of visual processing may have led to top-down endogenous attention mechanisms that process visual information in a way that no longer associates with automatic auditory perceptual sensitivity.

Tritium Beta Spectrum Measurement and Neutrino Mass Limit from Cyclotron Radiation Emission Spectroscopy. PHYSICAL REVIEW LETTERS 2023; 131:102502.

Abstract
The absolute scale of the neutrino mass plays a critical role in physics at every scale, from the subatomic to the cosmological. Measurements of the tritium end-point spectrum have provided the most precise direct limit on the neutrino mass scale. In this Letter, we present advances by Project 8 to the cyclotron radiation emission spectroscopy (CRES) technique culminating in the first frequency-based neutrino mass limit. With only a cm^{3}-scale physical detection volume, a limit of m_{β}<155 eV/c^{2} (152 eV/c^{2}) is extracted from the background-free measurement of the continuous tritium beta spectrum in a Bayesian (frequentist) analysis. Using ^{83m}Kr calibration data, a resolution of 1.66±0.19 eV (FWHM) is measured, the detector response model is validated, and the efficiency is characterized over the multi-keV tritium analysis window. These measurements establish the potential of CRES for a high-sensitivity next-generation direct neutrino mass experiment featuring low background and high resolution.

Abstract
Uterine leiomyomas are one of the most common reproductive pathologies in born females. The majority of women within reproductive age will develop a leiomyoma, most of which will be asymptomatic. Though there has been extensive research regarding this pathology alone, there is more to be learned about leiomyomas that affect women with other comorbidities. This case study reviews the medical and surgical management of a woman born with two uteri, medically termed congenital uterus didelphys. Within her reproductive years, she develops symptomatic leiomyomas in each of her uteri and seeks surgical management. This case study aims to widen the scientific knowledge surrounding these subsets of women with a common diagnosis superimposed on an extremely rare diagnosis.

Delivery Models and Health Economics of Supportive Care Services in England: A Multicentre Analysis. Clin Oncol (R Coll Radiol) 2023; 35:e395-e403. [PMID: 36997458 DOI: 10.1016/j.clon.2023.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 01/16/2023] [Accepted: 03/02/2023] [Indexed: 03/30/2023]
Abstract
AIMS Improvements in cancer treatment have led to more people living with and beyond cancer. These patients have symptom and support needs unmet by current services. The development of enhanced supportive care (ESC) services may meet the longitudinal care needs of these patients, including at the end of life. This study aimed to determine the impact and health economic benefits of ESC for patients living with treatable but not curable cancer. MATERIALS AND METHODS A prospective observational evaluation was undertaken over 12 months across eight cancer centres in England. ESC service design and costs were recorded. Data relating to patients' symptom burden were collected using the Integrated Palliative Care Outcome Scale (IPOS). For patients in the last year of life, secondary care use was compared against an NHS England published benchmark. RESULTS In total, 4594 patients were seen by ESC services, of whom 1061 died during follow-up. Mean IPOS scores improved across all tumour groups. In total, £1,676,044 was spent delivering ESC across the eight centres. Reductions in secondary care usage for the 1061 patients who died saved a total of £8,490,581. CONCLUSIONS People living with cancer suffer with complex and unmet needs. ESC services appear to be effective at supporting these vulnerable people and significantly reduce the costs of their care.

Effect of feeding a Saccharomyces cerevisiae fermentation product to Holstein cows exposed to high temperature and humidity conditions on milk production performance and efficiency-A pen-level trial. J Dairy Sci 2023:S0022-0302(23)00289-8. [PMID: 37268565 DOI: 10.3168/jds.2022-22516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 01/31/2023] [Indexed: 06/04/2023]
Abstract
The objective of this study was to evaluate the effect of feeding a Saccharomyces cerevisiae fermentation product (SCFP) on milk production efficiency of Holstein cows naturally exposed to high temperature and humidity conditions. The study was conducted in 2 commercial farms in Mexico from July to October 2020 and included 1 wk covariate period, 3 wk adaptation, and 12 wk data collection. Cows [n = 1,843; ≥21 d in milk (DIM) and <100 d carried calf] were enrolled and assigned to the study pens (n = 10) balanced for parity, milk yield, and DIM. Pens were fed a total mixed ration diet either without (CTRL) or with SCFP (19 g/d, NutriTek, Diamond V). Milk yield, energy-corrected milk (ECM), milk components, linear somatic cell score, dry matter intake (DMI), feed efficiency (FE; Milk/DMI and ECM/DMI), body condition score, and the incidence of clinical mastitis, pneumonia, and culling were monitored. Statistical analyses included mixed linear and logistic models accounting for repeated measures (when applicable; multiple measurements per cow within treated pens) with pen as the experimental unit and treatment, time (week of study), parity (1 vs. 2+), and their interactions as fixed and pen nested within farm and treatment as random effect. Parity 2+ cows within pens fed SCFP produced more milk than cows within CTRL pens (42.1 vs. 41.2 kg/d); there were no production differences between groups of primiparous groups. Cows within SCFP pens had lower DMI (25.2 vs. 26.0 kg/d) and greater FE (1.59 vs. 1.53) and ECM FE (1.73 vs. 1.68) than cows within CTRL pens. Milk components, linear somatic cell score, health events, and culling were not different between groups. At the end of the study (245 ± 54 DIM), SCFP cows had greater body condition score than CTRL (3.33 vs. 3.23 in the first parity; 3.11 vs. 3.04 in 2+ parity cows). Feeding Saccharomyces cerevisiae fermentation products to lactating cows exposed to high temperature and humidity conditions improved FE.

Abstract
Bioengineered probiotics enable new opportunities to improve colorectal cancer (CRC) screening, prevention and treatment strategies. Here, we demonstrate the phenomenon of selective, long-term colonization of colorectal adenomas after oral delivery of probiotic E. coli Nissle 1917 (EcN) to a genetically-engineered murine model of CRC predisposition. We show that, after oral administration, adenomas can be monitored over time by recovering EcN from stool. We also demonstrate specific colonization of EcN to solitary neoplastic lesions in an orthotopic murine model of CRC. We then exploit this neoplasia-homing property of EcN to develop early CRC intervention strategies. To detect lesions, we engineer EcN to produce a small molecule, salicylate, and demonstrate that oral delivery of this strain results in significantly increased levels of salicylate in the urine of adenoma-bearing mice, in comparison to healthy controls. We also assess EcN engineered to locally release immunotherapeutics at the neoplastic site. Oral delivery to mice bearing adenomas, reduced adenoma burden by ∼50%, with notable differences in the spatial distribution of T cell populations within diseased and healthy intestinal tissue, suggesting local induction of robust anti-tumor immunity. Together, these results support the use of EcN as an orally-delivered platform to detect disease and treat CRC through its production of screening and therapeutic molecules.

Abstract
INTRODUCTION The prevalence and complications of biliary disease increase with age. Frailty has been associated with adverse outcomes in the hospital setting. We describe the prevalence of frailty in older patients hospitalised with benign biliary disease and its association with duration of hospital stay, and 90-day and 1-year mortality. METHODS We performed a retrospective cohort study of patients aged 75 years and over admitted with acute biliary disease between 17 September 2014 and 20 March 2017. Clinical Frailty Scale (CFS) score was recorded on admission. RESULTS We included 200 patients with a median age of 82 (75-99) years, 60% were female; 154 (77%) were independent for personal activities of daily living (ADLs) and 99 (49.5%) for instrumental ADLs. Cholecystitis was the most common diagnosis (43%) followed by cholangitis (36%) and pancreatitis (21%). Ninety-nine patients were non frail (NF; CFS 1-4) and 101 were frail (F; CFS 5-9). Some 104 patients received medical treatment only. Surgery was more common in NF patients (11% vs F 2%), percutaneous drainage more frequently performed in F patients (15% vs NF 5%) and endoscopic cholangiopancreatography was similar in both groups (F 32% vs NF 31%). Frailty was associated with worse clinical outcomes in F vs NF: functional deconditioning (34% vs 11%), increased care level (19% vs 3%), length of stay (12 vs 7 days), 90-day mortality (8% vs 3%) and 1-year mortality (48% vs 24%). CONCLUSIONS Half of patients in our cohort were frail and spent longer in hospital, were less likely to undergo surgery and were less likely to remain alive at 1 year after discharge.

Abstract
AIM To assess whether routine cerebrovascular imaging is required in all major trauma (MT) patients. MATERIALS AND METHODS All MT patients with cerebrovascular imaging between January 2015 and December 2020 were included in the study. Data were collated regarding the type of indication for computed tomography (CT) angiography imaging, time interval from the initial trauma, relevant trauma diagnoses on initial trauma imaging, and CT angiography. Findings, such as aneurysms, vascular malformations, luminal thrombus, venous sinus thrombosis, or vascular injury, were collated. Subsequent treatment with anti-coagulants/anti-platelets or surgical/radiological intervention was noted. Follow-up imaging was assessed for residual injury or complications. RESULTS Two hundred and fifty of the 6,251 MT patients underwent dedicated cerebrovascular imaging and were included in the study. Of these 41 (16.4%) had cervical artery or venous sinus injury. Further positive vascular findings were identified in 25/250 patients who presented with an incidental stroke or a vascular abnormality and were mislabelled as MT patients at presentation. One patient with a carotid injury subsequently died following a large infarction. Another patient with vertebral artery injury suffered a non-lethal stroke. No patients underwent surgery or intervention. CONCLUSION The present study showed that the overall incidence of detected blunt cerebrovascular injuries was very low (0.6%) and even lower for symptomatic vascular injury (0.03%). Routine cerebrovascular imaging is not recommended in all MT trauma patients, but instead, a continued case-by-case basis should be considered.

Rhinitis associated with asthma is distinct from rhinitis alone: The ARIA-MeDALL hypothesis. Allergy 2023; 78:1169-1203.

Abstract
Asthma, rhinitis and atopic dermatitis (AD) are interrelated clinical phenotypes that partly overlap in the human interactome. The concept of "one-airway-one-disease", coined over 20 years ago, is a simplistic approach of the links between upper- and lower-airway allergic diseases. With new data, it is time to reassess the concept. This article reviews (i) the clinical observations that led to Allergic Rhinitis and its Impact on Asthma (ARIA), (ii) new insights into polysensitisation and multimorbidity, (iii) advances in mHealth for novel phenotype definition, (iv) confirmation in canonical epidemiologic studies, (v) genomic findings, (vi) treatment approaches and (vii) novel concepts on the onset of rhinitis and multimorbidity. One recent concept, bringing together upper- and lower-airway allergic diseases with skin, gut and neuropsychiatric multimorbidities, is the "Epithelial Barrier Hypothesis". This review determined that the "one-airway-one-disease" concept does not always hold true and that several phenotypes of disease can be defined. These phenotypes include an extreme "allergic" (asthma) phenotype combining asthma, rhinitis and conjunctivitis. Rhinitis alone and rhinitis and asthma multimorbidity represent two distinct diseases with the following differences: (i) genomic and transcriptomic background (Toll-Like Receptors and IL-17 for rhinitis alone as a local disease; IL-33 and IL-5 for allergic and non-allergic multimorbidity as a systemic disease), (ii) allergen sensitisation patterns (mono- or pauci-sensitisation versus polysensitisation), (iii) severity of symptoms and (iv) treatment response. In conclusion, rhinitis alone (local disease) and rhinitis with asthma multimorbidity (systemic disease) should be considered as two distinct diseases, possibly modulated by the microbiome, and may be a model for understanding the epidemics of chronic and auto-immune diseases.

Abstract
PURPOSE A negative socio-economic gradient exists for diet and health outcomes. Since cheaper diets are associated with increased energy and lower nutrient density, we investigated the influence of income on iron and zinc intakes and overall diet quality for adolescent (DQI-A) females aged 11-18 years. METHODS National Diet and Nutrition Survey (NDNS years 7 and 8) data for iron and zinc intake and overall diet quality was assessed by household income quintile across females aged 11-18 years. RESULTS Equivalised household income positively correlated with Diet quality index for adolescents (DQI-A) (P < 0.001) Females aged 15-18 years in income quintiles (IQs) I and 2, had a greater proportion of respondents with low to intermediate DQI-A score compared to higher IQs (P = 0.002). NDNS data showed intake was negatively influenced by income amongst females aged 11-14 years for iron (P = 0.009) and zinc (P = 0.001) with those from the lowest incomes consistently consuming significantly less than those from the highest. DQI-A was positively correlated with iron intakes for 11-14 (P = 0.001) and 15-18 years (P < 0.001). Forty-one percent of 15-18-year-olds plasma ferritin stores were below the 15 µg L-1 and 21% had some form of anaemia. Cereal and cereal products were the greatest contributors to iron in all groups. CONCLUSION Females in the lowest income groups are at greater risk of lower overall diet quality and inadequate iron and zinc intakes. Amongst older adolescents, there is evidence of iron stores being depleted and an increased prevalence of anaemia.

Abstract
BACKGROUND Pelvic exenteration surgery is complex, necessitating co-ordinated multidisciplinary input and improved referral pathways. A state-wide pelvic exenteration multidisciplinary team (MDT) meeting was established in SA and the outcomes of this were audited and compared with historical data. METHODS All patients referred for discussion between August 2021 and July 2022 to the SA State-wide Pelvic Exenteration MDT were included in this study. MDT discussion centred around disease resectability, risk versus benefit of surgery, and need for local or interstate referral. Prospective data collection included patient demographics and MDT recommendations of surgery, palliation, or referral. Patients referred for surgery locally or interstate were compared with a retrospective patient cohort treated previously between January and December 2020. RESULTS Over 12 months, 91 patients were discussed (including nine multiple times), by a mean of 18 meeting participants each month. Forty-eight patients (58.5%) had primary malignancy, 25 (30.5%) recurrent malignancy, and 9 (11.0%) had non-malignant disease. Colorectal cancer was the most common presentation (56.1%), followed by gynaecological (30.5%) and urological (6.1%) malignancy. Pelvic exenteration surgery was recommended to be performed locally in 53.7% of patients and the remainder for non-surgical treatment, palliation, or re-discussion. During this time, 44 patients underwent surgery locally (versus 34 in 2020) and only 4 referred interstate (versus 8 in 2020). CONCLUSION The establishment of a dedicated state-wide pelvic exenteration MDT has resulted in better coordination of care for patients with locally advanced pelvic malignancy in SA, and significantly reduced the need for interstate referral.

Abstract
The first UK lockdown greatly impacted the food security status of UK adults. This study set out to establish if food procurement was adapted differently for different income groups and if this impacted dietary intakes disproportionately. Adults (n = 515) aged 20-65 years participated in an online survey with 56 completing a 3-4 day diet diary. Food availability was a significant factor in the experience of food insecurity. Similar proportions of food secure and food insecure adapted food spend during lockdown, spending similar amounts. Food insecure (n = 85, 18.3%) had a 10.5% lower income and the money spent on food required a greater proportion of income. Access to food was the biggest driver of food insecurity but monetary constraint was a factor for the lowest income group. The relative risk of food insecurity increased by 0.07-fold for every 1% increase in the proportion of income spent on food above 10%. Micronutrient intakes were low compared to the reference nutrient intake (RNI) for most females, with riboflavin being 36% lower in food insecure groups (p = 0.03), whilst vitamin B12 was 56% lower (p = 0.057) and iodine 53.6% lower (p = 0.257) these were not significant. Coping strategies adopted by food insecure groups included altering the quantity and variety of fruit and vegetables which may have contributed to the differences in micronutrients.

Abstract
Next-generation Li-ion batteries must guarantee improved durability, quality, reliability, and safety to satisfy the stringent technical requirements of crucial sectors such as e-mobility. One breakthrough strategy to overcome the degradation phenomena affecting the battery performance is the development of advanced materials integrating smart functionalities, such as self-healing units. Herein, we propose a gel electrolyte based on a uniform and highly cross-linked network, hosting a high amount of liquid electrolyte, with multiple advantages: (i) autonomous, fast self-healing, and a promising PF5-scavenging role; (ii) solid-like mechanical stability despite the large fraction of entrapped liquid; and (iii) good Li+ transport. It is shown that such a gel electrolyte has very good conductivity (>1.0 mS cm-1 at 40 °C) with low activation energy (0.25 eV) for the ion transport. The transport properties are easily restored in the case of physical damages, thanks to the outstanding capability of the polymer to intrinsically repair severe cracks or fractures. The good elastic modulus of the cross-linked network, combined with the high fraction of anions immobilized within the polymer backbone, guarantees stable Li electrodeposition, disfavoring the formation of mossy dendrites with the Li metal anode. We demonstrate the electrolyte performance in a full-cell configuration with a LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode, obtaining good cycling performance and stability.

Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
Background: Rhino-orbito-cerebral-mucormycosis (ROCM), a rare and potentially fatal disease was seen in increasing numbers during the COVID-19 pandemic. This study describes and compares the patient characteristics and outcomes in COVID-19 associated mucormycosis (CAM) and non-COVID-19 mucormycosis (non-CAM). Methodology: CAM patients (24 cases) were recruited from the COVID-19 period and non-CAM (24 controls) from the pre-COVID-19 period. Clinical data of the CAM group was collected retrospectively with 3 month outcomes prospectively. The non-CAM group data was collected retrospectively. Patient characteristics were compared and risk factors for mortality in ROCM were assessed. Results: Orbital symptoms [altered vision, restricted eye movements, ptosis] and intracranial involvement were higher in CAM patients on presentation. Similarly, the radiological involvement of orbit (orbital apex, superior orbital fissure) and intracranial cavity (intracranial thrombosis, cavernous sinus) was also higher in CAM patients. Newly detected diabetes was found only in CAM patients (29.2%). Although univariate analysis suggested an increased mortality risk in ROCM patients with orbital involvement, the multivariate analysis showed no increased risk with any of the parameters assessed, including COVID-19 positivity. Conclusions: Compared to the non-CAM, the disease presentation was severe in CAM with higher frequency of orbital and intracranial involvement. However, with early detection and treatment, the short term survival was comparable in both groups.

Abstract
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M_{⊙} and 1.0 M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14 yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200] Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2 M_{⊙}<m_{PBH}<1.0 M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1 M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Abstract
BACKGROUND AND PURPOSE Craniofacial giant cell granulomas are rare lesions with varied appearances on imaging. We aimed to describe the imaging features of giant cell granulomas of the craniofacial bones. MATERIALS AND METHODS A retrospective analysis of the clinical features and imaging findings of 20 histopathology-proved cases of craniofacial giant cell granulomas, dating from 2006 to 2022, was performed. RESULTS Of the 20 cases, 10 each were seen in men and women. The epicenter of the lesions varied in location: in the maxilla in 8 patients, in the mandible in 5, in the temporal bone in 3, in the sphenoid/clivus in 3, and in the orbit in 1 patient. On the radiographs, the lesions appeared well-circumscribed, expansile, and lytic. On CT, the lesions were predominantly multiloculated, with thin septa, a soft-tissue component, and with expansion and remodeling of the underlying bone. On MR imaging, the solid component of the lesions was isointense on T1WI and hypointense on T2WI, with heterogeneous enhancement of the solid component and rim enhancement of the locules. Fluid-fluid levels were present in 3 patients. CONCLUSIONS Giant cell granulomas commonly present as locally aggressive, expansile, multiloculated lytic lesions, with solid as well as cystic areas. The solid component is typically hypointense on T2WI. Certain key imaging features of giant cell granulomas can aid the radiologist in narrowing the differential diagnosis.
