COVID-19 and Acute Sarcopenia.
The COVID-19 pandemic has had a devastating global impact, with older adults being most at risk of death from the disease. However, acute sarcopenia occurs in survivors of COVID-19; older adults and the most critically unwell patients are the most at risk. Acute sarcopenia is an under-recognised condition of acute muscle insufficiency, defined by declines in muscle function and/or quantity within six months, usually following a stressor event. This commentary reviews definition and mechanisms of acute sarcopenia in COVID-19 and suggests recommendations for research and clinical practice. Research should now focus on the longer-term consequences of acute sarcopenia in patients who have suffered from COVID-19. At the same time, clinicians need to be increasingly aware of the condition, and measurements of muscle strength, quantity, and physical performance should be embedded into clinical practice. Clinicians should consider the risks of acute sarcopenia when weighing up the risks and benefits of treatment (e.g. dexamethasone), and instigate multidisciplinary treatment including dietetics input
Survival Advantage of Upfront Surgery for Pancreatic Head Cancer Without Preoperative Biliary Drainage.
Introduction
Level 1 evidence from randomized trials demonstrates less complication when jaundiced patients with resectable pancreatic cancer proceed directly to surgery, rather than undergo preoperative biliary drainage (PBD) first. Although "fast track" surgery significantly increases the resectability rate, it is unknown whether this translates into a survival benefit. This study evaluated the effect of upfront surgery on long-term survival using an intention-to-treat (ITT) analysis.
Methods
Patients were identified from a prospectively maintained database, stratified according to whether or not they underwent PBD.
Results
Among 157 patients, 84 (54%) underwent PBD. Of these, 73% underwent surgery, compared to 100% of those without PBD (p<0.001). Reasons for not undergoing surgery were progression of cancer (N=11), progressive frailty (N=5), or PBD-related complication (N=7). In those who underwent surgery, PBD was associated with a longer time from diagnosis to surgery (median: 59 vs. 14 days, p<0.001), and a higher rate of unresectable cancer at surgery (26% vs. 3%, p<0.001). On an ITT basis, patients treated with PBD had significantly shorter survival, at a median of 15 vs. 19 months (HR: 1.59, 95% CI: 1.07-2.37, p=0.023). However, for the subset of patients who underwent resection, survival was similar in the two groups (HR: 1.07, 95% CI: 0.66-1.73, p=0.773).
Conclusions
A reduced time to surgery with avoidance of PBD offers survival benefit. This is only appreciated on ITT analysis, which includes patients who are initially considered candidates for surgery, but ultimately do not undergo surgery. Considering this 'hidden' cohort of patients is important when considering optimal pathways for the treatment of resectable pancreatic cancer
Understanding the principles of insulin use in type 1 and type 2 diabetes management.
The year 2021 marks 100 years since the Nobel Prize-winning discovery of insulin as a medical treatment for diabetes mellitus. Its discovery changed type 1 diabetes from a terminal condition with a short life expectancy to one of long-term management, with patients now often living long and fulfilling lives. Today, much of the advice, support and prescribing of insulin is undertaken by nurses, including general nurses and those specialising in diabetes. This article provides an overview of the principles of insulin use in the management of diabetes, with the aim of enhancing nursing knowledge and improving the care of patients with diabetes
Modernising case finding for α-antitrypsin deficiency by DNA sequencing of COPD patients.
Optimal management of acute kidney injury in critically ill patients with invasive fungal infections being treated with liposomal amphotericin B.
Critically ill patients are at risk of developing both acute kidney injury (AKI) and invasive fungal infections (IFIs). Prompt and efficient treatment of the IFI is essential for the survival of the patient. This article examines three distinct clinical situations where liposomal amphotericin B, a broad-spectrum antifungal agent, was successfully used in the setting of AKI. The first was infection in a 63-year-old man with bleeding oesophageal varices related to advanced liver disease. The second was gastrointestinal mucormycosis in a 74-year-old man who developed a small bowel obstruction following an autologous stem cell transplant for mantle cell lymphoma. The third was a infection in a 32-year-old woman on immunosuppression for a bilateral lung transplant for cystic fibrosis. In all three cases, liposomal amphotericin B was required for urgent management of the patient's IFI. We discuss the rationale for treatment with a potentially nephrotoxic agent in this setting
Glucocorticoids regulate AKR1D1 activity in human liver in vitro and in vivo.
Steroid 5β-reductase (AKR1D1) is highly expressed in human liver where it inactivates endogenous glucocorticoids and catalyses an important step in bile acid synthesis. Endogenous and synthetic glucocorticoids are potent regulators of metabolic phenotype and play a crucial role in hepatic glucose metabolism. However, the potential of synthetic glucocorticoids to be metabolised by AKR1D1 as well as to regulate its expression and activity has not been investigated. The impact of glucocorticoids on AKR1D1 activity was assessed in human liver HepG2 and Huh7 cells; AKR1D1 expression was assessed by qPCR and Western blotting. Genetic manipulation of AKR1D1 expression was conducted in HepG2 and Huh7 cells and metabolic assessments were made using qPCR. Urinary steroid metabolite profiling in healthy volunteers was performed pre- and post-dexamethasone treatment, using gas chromatography-mass spectrometry. AKR1D1 metabolised endogenous cortisol, but cleared prednisolone and dexamethasone less efficiently. In vitro and in vivo, dexamethasone decreased AKR1D1 expression and activity, further limiting glucocorticoid clearance and augmenting action. Dexamethasone enhanced gluconeogenic and glycogen synthesis gene expression in liver cell models and these changes were mirrored by genetic knockdown of AKR1D1 expression. The effects of AKR1D1 knockdown were mediated through multiple nuclear hormone receptors, including the glucocorticoid, pregnane X and farnesoid X receptors. Glucocorticoids down-regulate AKR1D1 expression and activity and thereby reduce glucocorticoid clearance. In addition, AKR1D1 down-regulation alters the activation of multiple nuclear hormone receptors to drive changes in gluconeogenic and glycogen synthesis gene expression profiles, which may exacerbate the adverse impact of exogenous glucocorticoids
Evaluation of a bundle of care to reduce incisional surgical site infection after gastrointestinal surgery.
Background
Surgical site infection (SSI) is associated with morbidity, mortality and increased care costs; many SSIs are considered preventable. The aim of the present study was to test implementation of a pragmatic, evidence-based bundle designed to reduce incisional SSI after emergency laparotomy and elective major lower gastrointestinal surgery.
Method
This was a prospective before-and-after study. Data were collected before the intervention and for two separate subsequent time periods. An evidence-based bundle of care (BOC) was implemented; the primary outcome measure was incisional SSI at 30 days. The secondary outcome measure was 30-day unplanned readmissions. The initial post-intervention group, Group 2, assessed a variable number of potential impacting factors; however, due to funding and staffing levels the second post-bundle group, Group 3, focused on the core aspects of the BOC and rates of incisional SSI and readmission.
Results
In total, 99 patients were included in the 'before' group; and 71 in Group 2 and 92 in Group 3, the post-intervention groups. The incisional SSI rate was 29.3% (29/99) before and 28.2% (20/71) in Group 2 (=0.873) and 21.7% (20/92) in Group 3 (=0.234) after the intervention. After adjustment for confounders, the care bundle was associated with a non-significant reduction in SSI (Group 2: odds ratio [OR] = 0.93, 95% confidence interval [CI] = 0.45-1.93, =0.0843). However, it was associated with significantly reduced readmissions 18.1% (18/99) before versus 5.6% (4/71) in Group 2 (OR = 0.236, 95% CI = 0.077-0.72, =0.012) and 8.7% (8/92) in Group 3 (OR = 0.38, 95% CI = 0.16-0.9, =0.029). Comparing the pre-bundle group to the post-bundle groups, there was an overall significant reduction in readmissions (=0.003). This implies a number needed to treat of 8-11 patients to prevent one readmission. Adherence to antibiotic prophylaxis with the Trust guidelines increased from 91% to 99% (1 vs. 2, =0.047).
Conclusion
Introduction of the bundle was associated with a reduction in the observed rate of incisional SSI from 29.3% to 21.7%; significantly fewer patients required unplanned readmission. Use of the bundle was associated with significantly improved compliance with appropriate antimicrobial prophylaxis
Impact of the eye clinic liaison officer at an NHS foundation trust: a retrospective study.
Objective
Vision loss has a significant impact on physical, mental and social well-being. Eye clinic liaison officers (ECLOs) have a crucial role in providing holistic care for patients with visual impairment. The aim of this study was to review the work of an ECLO over a period of 1 year at an NHS Trust to determine the volume of work and the areas of support provided by the ECLO.
Methods and Analysis
A secondary data analysis of the ECLO case notes for all patients reviewed by the ECLO at University Hospitals Birmingham (UHB) NHS Trust during the year 2019, was performed. Demographic data and certification of visual impairment (CVI) status were noted. The main outcome variable recorded was the categories of support provided by the ECLO. Case vignettes were chosen to illustrate the variety of support offered to individual patients.
Results
A total of 1127 consecutive participants were reviewed by the ECLO at University Hospitals Birmingham (UHB) NHS Trust during the year 2019. Areas of support most commonly provided by the ECLO included aiding the process of registration for CVI, and assistance in accessing benefits, social support and low vision support. Severely sight impaired patients required significantly more areas of support than sight impaired patients (Χ=52.7, p=2.16×10). Three case vignettes, chosen by the ECLO, highlighted the positive impact of the ECLO with respect to emotional support, practical advice and as a point of contact ensuring continuity of care, also during the COVID-19 pandemic.
Conclusions
The ECLO at UHB NHS Trust provides a core patient service within the ophthalmology department by being a key source of practical and emotional support and the crucial link between healthcare, social care and voluntary services
Primary mesenteric sarcomas: Collaborative experience from the Trans-Atlantic Australasian Retroperitoneal Sarcoma Working Group (TARPSWG).
BACKGROUND
Primary mesenteric soft tissue sarcomas (STS) are rare and limited evidence is available to inform management. Surgical resection is challenging due to the proximity of vital structures and a need to preserve enteric function.
OBJECTIVES
To determine the overall survival (OS) and recurrence-free survival (RFS) for patients undergoing primary resection for mesenteric STS.
METHODS
The Trans-Atlantic Australasian Retroperitoneal Sarcoma Working Group (TARPSWG) is an intercontinental collaborative comprising specialist sarcoma centers. Data were collected retrospectively for all patients with mesenteric STS undergoing primary resection between 2000 and 2019.
RESULTS
Fifty-six cases from 15 institutions were included. The spectrum of pathology was similar to the retroperitoneum, although of a higher grade. R0/R1 resection was achieved in 87%. Median OS was 56 months. OS was significantly shorter in higher-grade tumors (p = .018) and extensive resection (p < .001). No significant association between OS and resection margin or tumor size was detected. Rates of local recurrence (LR) and distant metastases (DM) at 5 years were 60% and 41%, respectively. Liver metastases were common (60%), reflecting portal drainage of the mesentery.
CONCLUSION
Primary mesenteric sarcoma is rare, with a modest survival rate. LR and DM are frequent events. Liver metastases are common, highlighting the need for surveillance imaging
