Patient-reported health outcomes of SARS-CoV-2-tested patients presenting to emergency departments: a propensity score-matched prospective cohort study

OBJECTIVE

This study aimed to compare the long-term physical and mental health outcomes of matched severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive and SARS-CoV-2-negative patients controlling for seasonal effects.

STUDY DESIGN

This was a retrospective cohort study.

METHODS

This study enrolled patients presenting to emergency departments participating in the Canadian COVID-19 Emergency Department Rapid Response Network. We enrolled consecutive eligible consenting patients who presented between March 1, 2020, and July 14, 2021, and were tested for SARS-CoV-2. Research assistants randomly selected four site and date-matched SARS-CoV-2-negative controls for every SARS-CoV-2-positive patient and interviewed them at least 30 days after discharge. We used propensity scores to match patients by baseline characteristics and used linear regression to compare Veterans RAND 12-item physical health component score (PCS) and mental health component scores (MCS), with higher scores indicating better self-reported health.

RESULTS

We included 1170 SARS-CoV-2-positive patients and 3716 test-negative controls. The adjusted mean difference for PCS was 0.50 (95% confidence interval [CI]: -0.36, 1.36) and -1.01 (95% CI: -1.91, -0.11) for MCS. Severe disease was strongly associated with worse PCS (β = -7.4; 95% CI: -9.8, -5.1), whereas prior mental health illness was strongly associated with worse MCS (β = -5.4; 95% CI: -6.3, -4.5).

CONCLUSION

Physical health, assessed by PCS, was similar between matched SARS-CoV-2-positive and SARS-CoV-2-negative patients, whereas mental health, assessed by MCS, was worse during a time when the public experienced barriers to care. These results may inform the development and prioritization of support programs for patients.

Growth and renal function dynamics of renal oncocytomas in patients on active surveillance

OBJECTIVES

To study the natural history of renal oncocytomas and address indications for intervention by determining how growth is associated with renal function over time, the reasons for surgery and ablation, and disease-specific survival.

PATIENTS AND METHODS

The study was conducted in a retrospective cohort of consecutive patients with renal oncocytoma on active surveillance reviewed at the Specialist Centre for Kidney Cancer at the Royal Free London NHS Foundation Trust (2012 to 2019). Comparison between groups was performed using Mann-Whitney U-tests and chi-squared tests. A mixed-effects model with a random intercept for patient was used to study the longitudinal association between tumour size and estimated glomerular filtration rate (eGFR).

RESULTS

Longitudinal data from 98 patients with 101 lesions were analysed. Most patients were men (68.3%) and the median (interquartile range [IQR]) age was 69 (13) years. The median (IQR) follow-up was 29 (26) months. Most lesions were small renal masses, and 24% measured over 4 cm. Over half (64.4%) grew at a median (IQR) rate of 2 (4) mm per year. No association was observed between tumour size and eGFR over time (P = 0.871). Nine lesions (8.9%) were subsequently treated. Two deaths were reported, neither were related to the diagnosis of renal oncocytoma.

CONCLUSION

Natural history data from the largest active surveillance cohort of renal oncocytomas to date show that renal function does not seem to be negatively impacted by growing oncocytomas, and confirms clinical outcomes are excellent after a median follow-up of over 2 years. Active surveillance should be considered the 'gold standard' management of renal oncocytomas up to 7cm.

Impact of the first surge of the COVID-19 pandemic on a tertiary referral centre for kidney cancer

Objective

To analyse the impact of the COVID‐19 pandemic on a centralized specialist kidney cancer care pathway.

Materials and Methods

We conducted a retrospective analysis of patient and pathway characteristics including prioritization strategies at the Specialist Centre for Kidney Cancer located at the Royal Free London NHS Foundation Trust (RFH) before and during the surge of COVID‐19.

Results

On 18 March 2020 all elective surgery was halted at RFH to redeploy resources and staff for the COVID‐19 surge. Prioritizing of patients according to European Association of Urology guidance was introduced. Clinics and the specialist multidisciplinary team (SMDT) meetings were maintained with physical distancing, kidney surgery was moved to a COVID‐protected site, and infection prevention measurements were enforced. During the 7 weeks of lockdown (23 March to 10 May 2020), 234 cases were discussed at the SMDT meetings, 53% compared to the 446 cases discussed in the 7 weeks pre‐lockdown. The reduction in referrals was more pronounced for small and asymptomatic renal masses. Of 62 low‐priority cancer patients, 27 (43.5%) were deferred. Only one (4%) COVID‐19 infection occurred postoperatively, and the patient made a full recovery. No increase in clinical or pathological upstaging could be detected in patients who underwent deferred surgery compared to pre‐COVID practice.

Conclusion

The first surge of the COVID‐19 pandemic severely impacted diagnosis, referral and treatment of kidney cancer at a tertiary referral centre. With a policy of prioritization and COVID‐protected pathways, capacity for time‐sensitive oncological interventions was maintained and no immediate clinical harm was observed.

Emotional demands, compassion and mental health in social workers

BACKGROUND

Compassion, described as the act of providing care based on empathy, dignity and respect, is intrinsic to effective health and social care. Although delivering compassionate care has wide-ranging benefits for service users, more insight is needed into its effects on health and social care professionals. The emotional demands of 'helping' work can engender compassion fatigue that may impair well-being, whereas compassion satisfaction and feelings of compassion towards the self could be protective.

AIMS

To examine the effects (direct and indirect) of compassion satisfaction, compassion fatigue and self-compassion on mental health in a cohort of social workers.

METHODS

We used validated scales to measure emotional demands, compassion satisfaction and fatigue, and self-compassion and the General Health Questionnaire-12 to assess mental health. We tested the main and moderating effects of emotional demands and the three facets of compassion using hierarchical regression analysis.

RESULTS

The study sample comprised 306 social workers (79% female). Participants who reported higher levels of compassion satisfaction and self-compassion tended to report better mental health, whereas compassion fatigue was a significant risk factor for well-being. The models explained 44-53% of the variance in mental health symptoms. We found some evidence that compassion satisfaction and self-compassion buffer the negative effects of emotional demand on mental health, contributing 2 and 3%, respectively, to the incremental variance.

CONCLUSIONS

Our findings suggest that evidence-based interventions are needed to reduce compassion fatigue and enhance compassion satisfaction and self-compassion in social care work. We consider ways to accomplish this using targeted interventions.

Renal tumor biopsy to reduce overtreatment of renal oncocytomas

623

Background: Up to 30% of renal masses are benign tumours, the most common of which is renal oncocytomas (RO). Our practice is to offer renal tumour biopsy (RTB) for small renal masses (SRM; ≤4cm) as part of a multi-disciplinary pathway. Our objective was to determine whether RTB influenced the management of RO. Methods: Retrospective descriptive analysis of the management of all sporadic cases with a histological diagnosis of RO (biopsy or surgical) at a high-volume tertiary centre from January/2012 to June/2019. Results: 170 patients (66% male; median age 67 years; median age-related Charlson comorbidity index 3) were diagnosed with 177 RO (median size 36mm). 70% (124) of RO were diagnosed using tumour biopsy (median size 33mm), of which 116 (93.4%) embarked on active surveillance (AS; 101) or watchful waiting (15). 53 (30%) RO were diagnosed after surgical excision (median size 50mm; 15 partial and 38 radical nephrectomies), of which 4 lesions were initially managed with AS. Median follow-up on AS was 20 months (2 to 84 months), with a median decrease in estimated glomerular filtration rate of 3 ml/min/1.73m2 over this period. 79% of RO on AS were SRMs. Median overall lesion size change was 1.1mm/year during follow up. Overall 62.6% of lesions grew, a quarter of which at a rate >5mm/year. Nine cases of RO on AS changed to intervention due to lesion growth or patient choice. No metastases were reported in the whole cohort. Three patients on AS died (stroke, respiratory arrest secondary to food inhalation, and unknown cause). One patient who had had surgical excision of RO died of unknown cause. Conclusions: Surgical risks for benign renal lesions are not different to those taken for renal cell carcinoma. RTB reduces the use of unnecessary surgery and its incumbent morbidity for benign renal lesions, such as RO. AS is a safe management option for patients with RO and can be used to reduce overtreatment-associated harm.

Protocol for a feasibility study of a cohort embedded randomised controlled trial comparing phron paring reatment (NEST) for small renal masses

INTRODUCTION

Small renal masses (SRMs; ≤4 cm) account for two-thirds of new diagnoses of kidney cancer, the majority of which are incidental findings. The natural history of the SRM seems largely indolent. There is an increasing concern regarding surgical overtreatment and the associated health burden in terms of morbidity and economy. Observational data support the safety and efficacy of percutaneous cryoablation but there is an unmet need for high-quality evidence on non-surgical management options and a head-to-head comparison with standard of care is lacking. Historical interventional trial recruitment difficulties demand novel study conduct approaches. We aim to assess if a novel trial design, the cohort embedded randomised controlled trial (RCT), will enable carrying out such a comparison.

METHODS AND ANALYSIS

Single-centre prospective cohort study of adults diagnosed with SRM (n=200) with an open label embedded interventional RCT comparing nephron sparing interventions. Cohort participants will be managed at patient and clinicians' discretion and agree with longitudinal clinical data and biological sample collection, with invitation for trial interventions and participation in comparator control groups. Cohort participants with biopsy-proven renal cell carcinoma eligible for both percutaneous cryoablation and partial nephrectomy will be randomly selected (1:1) and invited to consider percutaneous cryoablation (n=25). The comparator group will be robotic partial nephrectomy (n=25). The primary outcome of this feasibility study is participant recruitment. Qualitative research techniques will assess barriers and recruitment improvement opportunities. Secondary outcomes are participant trial retention, health-related quality of life, treatment complications, blood transfusion rate, intensive care unit admission and renal replacement requirement rates, length of hospital stay, time to return to pre-treatment activities, number of work days lost, and health technologies costs.

ETHICS AND DISSEMINATION

Ethical approval has been granted (UK HRA REC 19/EM/0004). Study outputs will be presented and published.

Risk factors for transplant renal artery stenosis after live donor transplantation

Background

Renal transplant surgeons are making increasing use of live donor kidneys with multiple renal arteries. This study aimed to identify independent risk factors for the development of transplant renal artery stenosis (TRAS) in the modern era of complex arterial reconstruction for multiple vessels.

Methods

Multivariable logistic regression analysis with a stepwise variable deletion model was used to identify risk factors for the development of TRAS in a consecutive series of live donor kidney transplants.

Results

Of 506 kidney transplants, 19 (3·8 per cent) had evidence of significant TRAS on CT angiography. Functional TRAS, defined by improvement in BP control or renal function after correction of a stenosis by angioplasty, occurred in 13 of 506 patients (2·6 per cent). Independent risk factors for TRAS were: use of an explanted internal iliac artery graft from the recipient (odds ratio (OR) 4·95; P = 0·020) and total ischaemia time (OR 1·82; P = 0·010). TRAS was associated with a lower 5-year allograft survival rate (79 versus 88·7 per cent; P = 0·020) but only one graft loss was attributed directly to TRAS. The 5-year allograft survival rate after internal iliac artery grafting was 86 per cent.

Conclusion

Although use of an internal iliac artery graft is an independent risk factor for TRAS after live donor kidney transplantation, this technique is still a useful option for complex arterial reconstruction.

Assessment of Palliative Care Needs in Hospital Settings in Rwanda

Background: Rwanda is among the first African countries with a palliative care (PC) policy and implementation plan. A partnership with the Ministry of Health (MoH) through the Rwanda Biomedical Centre (RBC) and the University of Edinburgh has supported an integrated approach including expanding the evidence base. Aim: To assessing the need for (PC) to inform policy, service delivery and training. Methods: A point prevalence PC needs assessment was conducted in nine public hospitals (referral, provincial and district). A records census identified those with life-limiting illness (LLI) who were then invited to participate by interview. The assessment tool included the APCA African POS, POS S, WHO performance status and demographic information. Results: 608 case notes were reviewed, 152 eligible and 124 completed assessment. 25% of all patients admitted had LLI, of which 99.2% had evidence of unmet need determined by at least one score on the APCA POS ≥ 3. Diagnoses 29% cancer, 29% cardiovascular disease, 16.9% end-stage organ failure and 13.7% HIV. Symptoms with greatest impact; nausea and vomiting (34.7%) and pain (32.3%). 63.7% with WHO performance status 4 or 5. 8.1% seen by existing PC services. Conclusion: Although the MoH and RBC are making bold steps toward developing PC in Rwanda, there remains a significant amount of unmet PC needs. Meeting this need requires recognition of the scope of PC needs beyond cancer, feedback to the hospitals and health care workers, thinking strategically how to further strengthen the health system and further capacity building and training.

Home-Based Care Practitioners: A Strategy for Continuum of Care for Very Ill Patient

Background: Rwanda Ministry of Health in collaboration with partners has initiated an innovative initiative named Home Based Care Practitioners (HBCPs) to respond to the burden of long-term hospitalization for end of life patients. Aim: The program aims at providing home-based care to accompany patients and their families in their home, reduce unnecessary pain and suffering for those with chronic or terminal conditions, provide counseling to the patients and their families, early diagnosis of NCDs and improve awareness on prevention of NCDs risk factors and effectively refer them to either health facilities or community-based resources that can be of further help. Methods: The HBCPs is implemented into phases; phase one has started with a pilot of 200 HBCPs in 100 cells surrounding nine provincial and referral hospitals of Rwanda; 2 practitioners for both gender in each cell, with a criteria of completion at least secondary school. They have undergone a training of 120 credits (900 hours), equivalent of four months for theory and two months of practice. After training they have been deployed into the community with a supervision of health centers in collaboration with hospitals and Rwanda Biomedical Center. Results: During the implementation period of 6 months, 1663 NCDs patients have been transferred from health facility (OPD) to HBCPs for routine follow-up, 482 palliative care patients have been reported on end of life care by HBCPs, there is a remarkable linkage between facilities and community care ensured by supervisory relationship between health services providers and home based care practitioners, long-term admission has reduced the cost for the family and the facility due to the discharge of care from hospital to home. Conclusion: In a limited setting of social and economic cost of providing frivolous care in an expensive hospital for chronic or terminal conditions that would be better managed through treatment or palliative care at home (or less acute setting) home based care effort can better meet the needs of Rwandans at the community level and has started to show the efficiency in providing quality care to people in need of palliative care.

Evaluation of Clinical Prognostic Factors and Further Delineation of the Effect of Mesenteric Fibrosis on Survival in Advanced Midgut Neuroendocrine Tumours

BACKGROUND

Small intestinal neuroendocrine tumours (SI NETs) represent 30-50% of small bowel neoplasms and often present at an advanced stage. To date, there is relatively limited literature regarding prognostic factors affecting overall survival (OS) in stage IV disease. In addition, the prevalence of mesenteric fibrosis (MF) in SI NETs and its effect on OS have not been sufficiently explored in the literature.

AIM

The primary aim of this study was to perform a large-scale survival analysis in an institutional cohort of 387 patients with metastatic (stage IV) SI NETs. The secondary aim was to provide epidemiological information regarding the prevalence of MF and to evaluate its effect on OS.

RESULTS

The median OS was 101 months (95% CI 84, 118). Age > 65 years, mesenteric metastases with and without desmoplasia, liver metastases, carcinoid heart disease (CHD) and bone metastases were associated with a significantly shorter OS, while primary tumour resection was predictive of a longer OS. The benefit of surgical resection was limited to symptomatic patients. MF was present in approximately 50% of patients with mesenteric lymphadenopathy. Elevated urinary 5-HIAA levels correlated strongly with the presence of CHD (p < 0.001) and to a lesser extent (p = 0.02) with MF. MF and CHD did not usually co-exist, suggesting that different mechanisms are likely to be involved in the development of these fibrotic complications.

CONCLUSIONS

This study has identified specific prognostic factors in a large cohort of 387 patients with advanced SI NETs and has provided useful epidemiological data regarding carcinoid-related fibrotic complications.

Myeloid protein tyrosine phosphatase 1B (PTP1B) deficiency protects against atherosclerotic plaque formation in the ApoE-/- mouse model of atherosclerosis with alterations in IL10/AMPKα pathway

Objective

Cardiovascular disease (CVD) is the most prevalent cause of mortality among patients with Type 1 or Type 2 diabetes, due to accelerated atherosclerosis. Recent evidence suggests a strong link between atherosclerosis and insulin resistance due to impaired insulin receptor (IR) signaling. Moreover, inflammatory cells, in particular macrophages, play a key role in pathogenesis of atherosclerosis and insulin resistance in humans. We hypothesized that inhibiting the activity of protein tyrosine phosphatase 1B (PTP1B), the major negative regulator of the IR, specifically in macrophages, would have beneficial anti-inflammatory effects and lead to protection against atherosclerosis and CVD.

Methods

We generated novel macrophage-specific PTP1B knockout mice on atherogenic background (ApoE^−/−/LysM-PTP1B). Mice were fed standard or pro-atherogenic diet, and body weight, adiposity (echoMRI), glucose homeostasis, atherosclerotic plaque development, and molecular, biochemical and targeted lipidomic eicosanoid analyses were performed.

Results

Myeloid-PTP1B knockout mice on atherogenic background (ApoE^−/−/LysM-PTP1B) exhibited a striking improvement in glucose homeostasis, decreased circulating lipids and decreased atherosclerotic plaque lesions, in the absence of body weight/adiposity differences. This was associated with enhanced phosphorylation of aortic Akt, AMPKα and increased secretion of circulating anti-inflammatory cytokine interleukin-10 (IL-10) and prostaglandin E2 (PGE₂), without measurable alterations in IR phosphorylation, suggesting a direct beneficial effect of myeloid-PTP1B targeting.

Conclusions

Here we demonstrate that inhibiting the activity of PTP1B specifically in myeloid lineage cells protects against atherosclerotic plaque formation, under atherogenic conditions, in an ApoE^−/− mouse model of atherosclerosis. Our findings suggest for the first time that macrophage PTP1B targeting could be a therapeutic target for atherosclerosis treatment and reduction of CVD risk.

•

PTP1B inhibition as therapy for atherosclerosis/cardiovascular disease is proposed.

•

Myeloid-PTP1B mice on ApoE^−/− background (ApoE^−/−/LysM-PTP1B) were generated.

•

ApoE^−/−/LysM-PTP1B had improved glucose homeostasis with no body weight differences.

•

ApoE^−/−/LysM-PTP1B had lower lipids and protection against atherosclerotic plaques.

•

Protection was via a PGE₂/IL-10/AMPKα mechanism.

The relationships between golf and health: a scoping review

OBJECTIVE

To assess the relationships between golf and health.

DESIGN

Scoping review.

DATA SOURCES

Published and unpublished reports of any age or language, identified by searching electronic databases, platforms, reference lists, websites and from consulting experts.

REVIEW METHODS

A 3-step search strategy identified relevant published primary and secondary studies as well as grey literature. Identified studies were screened for final inclusion. Data were extracted using a standardised tool, to form (1) a descriptive analysis and (2) a thematic summary.

RESULTS AND DISCUSSION

4944 records were identified with an initial search. 301 studies met criteria for the scoping review. Golf can provide moderate intensity physical activity and is associated with physical health benefits that include improved cardiovascular, respiratory and metabolic profiles, and improved wellness. There is limited evidence related to golf and mental health. The incidence of golfing injury is moderate, with back injuries the most frequent. Accidental head injuries are rare, but can have serious consequences.

CONCLUSIONS

Practitioners and policymakers can be encouraged to support more people to play golf, due to associated improved physical health and mental well-being, and a potential contribution to increased life expectancy. Injuries and illnesses associated with golf have been identified, and risk reduction strategies are warranted. Further research priorities include systematic reviews to further explore the cause and effect nature of the relationships described. Research characterising golf's contribution to muscular strengthening, balance and falls prevention as well as further assessing the associations and effects between golf and mental health are also indicated.

The relationship and effects of golf on physical and mental health: a scoping review protocol

INTRODUCTION

Golf is a sport played in 206 countries worldwide by over 50 million people. It is possible that participation in golf, which is a form of physical activity, may be associated with effects on longevity, the cardiovascular, metabolic and musculoskeletal systems, as well as on mental health and well-being. We outline our scoping review protocol to examine the relationships and effects of golf on physical and mental health.

METHODS AND ANALYSIS

Best practice methodological frameworks suggested by Arksey and O'Malley, Levac et al and the Joanna Briggs Institute will serve as our guide, providing clarity and rigour. A scoping review provides a framework to (1) map the key concepts and evidence, (2) summarise and disseminate existing research findings to practitioners and policymakers and (3) identify gaps in the existing research. A three-step search strategy will identify reviews as well as original research, published and grey literature. An initial search will identify suitable search terms, followed by a search using keyword and index terms. Two reviewers will independently screen identified studies for final inclusion.

DISSEMINATION

We will map key concepts and evidence, and disseminate existing research findings to practitioners and policymakers through peer-reviewed and non-peer reviewed publications, conferences and in-person communications. We will identify priorities for further study. This method may prove useful to examine the relationships and effects of other sports on health.
