Impacts of Omega-3 Fatty Acids, Natural Elixirs for Neuronal Health, on Brain Development and Functions.

Omega-3 fatty acids play a seminal role in maintaining the structural and functional integrity of the nervous system. These specialized molecules function as precursors for many lipid-based biological messengers. Also, studies suggest the role of these fatty acids in regulating healthy sleep cycles, cognitive ability, brain development, etc. Dietary intake of essential poly unsaturated fatty acids (PUFA) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are foundational to the optimal working of the nervous system. Besides regulating health, these biomolecules have great therapeutic value in treating several diseases, particularly nervous system diseases and disorders. Many recent studies conclusively demonstrated the beneficial effects of Omega-3 fatty acids in treating depression, neuropsychiatric disorders, neurodegenerative disorders, neurochemical disorders, and many other illnesses associated with the nervous system. This chapter summates the multifaceted role of poly unsaturated fatty acids, especially Omega-3 fatty acids (EPA and DHA), in the neuronal health and functioning. The importance of dietary intake of these essential fatty acids, their recommended dosages, bioavailability, the mechanism of their action, and therapeutic values are extensively discussed.

Thermoalkalophilic polygalacturonase from a novel Glutamicibacter sp.: Bioprospecting, strain improvement, statistical optimization and applications.

The current research discusses a multidimensional bioprocess development, that includes bioprospecting, strain improvement, media optimisation, and applications of the extracted enzyme. A potent alkalophilic polygalacturonase (PG) producing bacterial strain was isolated and identified as a novel Glutamicibacter sp. Furthermore, strain improvement by UV and chemical mutagenesis not only improved the enzyme (PGmut) production but also enhanced its temperature optima from 37 °C to 50 °C. The use of solid substrate fermentation, followed bystatistical optimisation through PB and RSM, substantially increasedPGmut production. A 10-fold increase in enzyme production (632 U/gm) was observed when sugarcane bagasse with a pH of 10.5, 66.8 % moisture, and an inoculum size of 10.15 % was used. The model's accuracy was supported by p-value (p < 0.0001), and an R2 of 0.9940. A pilot-scale experiment, demonstrated ≈ 62,229 U/100 gm PG activity. Additionally, the enzyme's efficacy in demucilization of coffee beans, and bioscouring of jute fibre indicated that it is a valuable biocatalyst.

Feasibility and safety of a surgical training program in total laparoscopic hysterectomy: Results of a pilot trial.

BACKGROUND: It is widely accepted total laparoscopic hysterectomy (TLH) and vaginal hysterectomy are less invasive procedures compared to total abdominal hysterectomy (TAH). However, rates of TAH remain unreasonably high. AIM: To pilot-test a model of training for practising obstetricians and gynaecologists (O&Gs) in TLH. MATERIALS AND METHODS: Training of participating O&Gs was conducted across four hospitals in Queensland, Australia, while other O&Gs were observed as contemporary controls. Type of hysterectomy, details of the surgery, including adverse events, were collected from hospital medical records. RESULTS: Eleven O&Gs completed the pre-intervention and intervention training periods, and nine completed the post-intervention follow-up. TLH rates increased from 24% prior to 75% during and 68% after intervention. Overall, the uptake rate of TLH showed a two-fold increase during the intervention period (2.08, 95% CI: 1.16-8.56, P < 0.001) and a 12% increase was retained during the follow-up period (1.12, 95% CI: 0.54-4.02, P = 0.427). Pre-intervention, across all sites, 24% of hysterectomies were performed via TAH by the participating specialist trainees, which decreased to 13% during the intervention and 14% during follow-up. The rate of adverse events decreased from 13.5% at pre-intervention, to 6.4% during and 4.2% post-intervention. By comparison, no change in surgical approach or rate of adverse events was observed in the control group. CONCLUSIONS: The implementation of a formal and structured surgical training program teaching TLH resulted in important benefits to trainees, patients and society in the four trial hospitals.

Novel approaches for leadless pacemaker implantation in the extra-cardiac Fontan cohort: Options to avoid leaded systems or epicardial pacing.

BACKGROUND: Fontan surgery, a palliative procedure for single ventricle patients, often leads to the need for permanent pacing. Epicardial pacing has limitations, while transvenous pacing carries risks in the Fontan circulation. This case series introduces a novel approach of leadless pacemaker implantation in the extra-cardiac Fontan (ECF) cohort to overcome these limitations. METHODS: The study includes four cases of leadless pacemaker (Micra™) implantation in patients with ECF. Procedures were performed under general anesthesia with guidance from trans-esophageal echocardiography. Various access routes were used, including trans-carotid and trans-fenestration approaches. Procedural details, parameters, and follow-up data were collected. RESULTS: All leadless pacemaker implantations were successful, with satisfactory electrical parameters and stable pacing postprocedural outcomes during short-term follow-up. One patient required closure of their fenestration for symptomatic desaturation post procedurally. CONCLUSIONS: Leadless pacemaker implantation via trans-carotid and trans-fenestration approaches appears to be a feasible back up option for pacing in Fontan patients where other options have been exhausted or there is a patient choice to avoid surgery. These techniques provide an option to avoid leaded systems or epicardial pacing, reducing the need for multiple thoracotomies and addressing challenges associated with surgical pacing leads. Further studies are needed to evaluate long-term outcomes and assess the broader application of leadless pacemakers in the Fontan population.

Effect of Metrics-Based Simulation Training to Proficiency on Procedure Quality and Errors Among Novice Cardiac Device Implanters: The IMPROF Randomized Trial.

Importance: In cardiac device implant training, there is no common system to objectively assess trainees' ability to perform tasks at predetermined performance levels before in vivo practice; therefore, patients are potentially exposed to risks related to operators' early learning curve. Objective: To assess the effect on implant performance quality of novel metrics-based simulation training to proficiency (proficiency-based progression [PBP]) vs traditional simulation-based training (SBT). Design, Setting, and Participants: In this prospective randomized trial, conducted between March 8, 2022 and November 24, 2022, novice implanters were randomized (blinded) 1:1 to participate in an SBT curriculum (procedural knowledge e-learning and in-person simulation training) at an international skills training center, with proficiency demonstration requirements at each training stage for advancing (PBP approach) or without the requirements. Ultimately, trainees performed a cardiac resynchronization therapy (CRT) implant using virtual reality simulation. The procedure was video-recorded and subsequently scored using previously validated metrics by 2 independent assessors blinded to group. Physicians who had already implanted more than 20 pacemakers or defibrillators and fewer than 200 CRT systems as the first operator were eligible. Thirty-two implanters from 10 countries voluntarily enrolled in the training program and were randomized; 30 (15 per group) started and completed training. Data analysis was performed from November 27 to December 22, 2022. Intervention: Training with PBP vs SBT. Main Outcome and Measures: The primary outcome comprised 4 objectively assessed performance metrics derived from the video-recordings: number of procedural steps completed, errors, critical errors, and all errors combined. Results: Baseline experience of the 30 participants (19 [63%] male; mean [SD] number of years in implant practice, 2.0 [1.8]; median [IQR] number of implanted pacemakers or defibrillators, 47.5 [30.0-115.0]; median [IQR] number of implanted CRT systems, 3.0 [1.25-10.0]) was similar between study groups. Compared with the SBT group, the PBP group completed 27% more procedural steps (median [IQR], 31 [30-32] vs 24 [22-27]; P < .001) and made 73% fewer errors (median [IQR], 2 [1-3] vs 7 [5-8]; P < .001), 84% fewer critical errors (median [IQR], 1 [0-1] vs 3 [3-5]; P < .001), and 77% fewer all errors combined (errors plus critical errors) (median [IQR], 3 [1-3] vs 11 [8-12]; P < .001); 14 of the 15 PBP trainees (93%) demonstrated the predefined target performance level vs 0 of the 15 SBT trainees. Conclusions and Relevance: In this randomized trial, the PBP approach to novice implanter training generated superior objectively assessed performance vs SBT. If implemented broadly and systematically, PBP training may ensure safe and effective performance standards before trainees proceed to (supervised) in vivo practice. Future studies are needed to verify implications on procedure-related patient complications. Trial Registration: ClinicalTrials.gov Identifier: NCT05952908.

Outcomes of Atrioventricular Node Ablation and Pacing in Patients with Heart Failure and Atrial Fibrillation: From Cardiac Resynchronization Therapy to His Bundle Pacing.

Objective: To review the relevant literature on the use of atrioventricular node ablation and pacing in patients with heart failure and atrial fibrillation. Methods: APubMed/MEDLINE and SCOPUS search was performed in order to assess the clinical outcomes of atrioventricular node ablation and pacemaker implantation, as well as the complications that may occur. Results: Several clinical trials, observational analyses and meta-analyses have shown that the "pace and ablate" strategy not only improves symptoms but also can enhance cardiac performance in patients with heart failure and atrial fibrillation. Although this procedure is effective and safe, some complications may occur including worsening of heart failure, permanent fibrillation, arrhythmias and sudden death. Regarding pacemaker implantation, cardiac resynchronization therapy is shown to be the optimal choice compared to right ventricle apical pacing. His bundle pacing is a promising alternative to cardiac resynchronization therapy and has shown beneficial effects, while left bundle branch pacing is an innovative modality. Conclusions: Atrioventricular node ablation and pacemaker implantation is shown to have beneficial effects on clinical outcomes of patients with atrial fibrillation ± heart failure who do not respond or are intolerant to medical treatment. Cardiac resynchronization therapy is the treatment of choice and His bundle pacing seems to be an effective alternative way of pacing in these patients.

Heart Failure and Cardiac Device Therapy: A Review of Current National Institute of Health and Care Excellence and European Society of Cardiology Guidelines.

Guidelines help clinicians to deliver high-quality care with therapies based on up-to-date evidence. There has been significant progress in the management of heart failure with regards to both medication and cardiac device therapy. These advances have been incorporated into national and international guidelines with varying degrees of success. This article reviews current guidance from the National Institute of Health and Care Excellence in the UK and compares this with European Society of Cardiology guidelines, and evaluates how differences between them may impact on clinical practice.

Extrinsic and intrinsic modulators of inflammation-resolution signaling in heart failure.

Chronic and uncleared inflammation is the root cause of various cardiovascular diseases. Fundamentally, acute inflammation is supportive when overlapping with safe clearance of inflammation termed resolution; however, if the lifestyle-directed extrinsic factors such as diet, sleep, exercise, or physical activity are misaligned, that results in unresolved inflammation. Although genetics play a critical role in cardiovascular health, four extrinsic risk factors-unhealthy processed diet, sleep disruption or fragmentation, sedentary lifestyle, thereby, subsequent stress-have been identified as heterogeneous and polygenic triggers of heart failure (HF), which can result in several complications with indications of chronic inflammation. Extrinsic risk factors directly impact endogenous intrinsic factors, such as using fatty acids by immune-responsive enzymes [lipoxygenases (LOXs)/cyclooxygenases (COXs)/cytochromes-P450 (CYP450)] to form resolution mediators that activate specific resolution receptors. Thus, the balance of extrinsic factors such as diet, sleep, and physical activity feed-forward the coordination of intrinsic factors such as fatty acids-enzymes-bioactive lipid receptors that modulates the immune defense, metabolic health, inflammation-resolution signaling, and cardiac health. Future research on lifestyle- and aging-associated molecular patterns is warranted in the context of intrinsic and extrinsic factors, immune fitness, inflammation-resolution signaling, and cardiac health.

Experience of practicing obstetrician-gynecologists in a surgical training program in total laparoscopic hysterectomy.

BACKGROUND: Advanced surgical techniques, such as total laparoscopic hysterectomy, are often challenging to acquire beyond fellowship training programs for practicing obstetrician-gynecologists. A lack of formative data currently exist for continuing medical education programs, limiting our understanding of how improvement in surgical skills and training programs occur. OBJECTIVE: This study aimed to investigate how practicing obstetrician-gynecologists acting as trainees experience a program that aims to teach them total laparoscopic hysterectomy, and to assess whether their surgical skills improve according to data from formative assessment tools and qualitative data from open-ended survey questions and in-depth interviews. STUDY DESIGN: We report a process analysis of formative data collected during a pilot implementation trial of a surgical training program targeting practicing obstetrician-gynecologists. Eleven consultant obstetrician-gynecologists and 4 experienced surgical mentors participated in 4 hospitals in Queensland, Australia. Total laparoscopic hysterectomy was performed in 700 patients over the course of the study. A total laparoscopic hysterectomy surgical mentorship training program of 10 training days with up to 3 total laparoscopic hysterectomy procedures per day was performed. Both the obstetrician-gynecologists and the surgical mentor completed a formative assessment questionnaire analyzing the trainee's performance after each surgical procedure. Mentors were formatively assessed by the Structured Training Trainer Assessment Report (STTAR) and at the completion of the study by the mini-STTAR, a summative assessment of quality of mentorship. Obstetrician-gynecologists, mentors, hospital leaders, and surgical administrative staff participated in qualitative interviews about the training program. RESULTS: Over time, there was a demonstrated improvement in trainee performance reported by both mentors and trainees in all competency assessment tool domains as the case number increased, with mentors consistently rating trainees' performance higher than the trainees themselves. Most trainees were satisfied with their mentor in all 31 areas during formative assessment, and at the end of the training, structure, attributes, and role modeling were all rated high (average score >4.5; range, 3.79-5.00), whereas training behavior was rated slightly lower at 4.1 (range, 3.79-4.45). Qualitative interviews demonstrated that the trainees found the training to be a beneficial, hands-on experience. CONCLUSION: Formative assessment clearly documented improvement in surgical skills during a total laparoscopic hysterectomy training program for consultant obstetrician-gynecologists.

Assessing the Cost and Resource Use Impact of Implantable Cardiac Defibrillator Shocks in the UK CareLink Population.

Objective: High voltage devices (implantable cardiac defibrillators (ICDs) and cardiac resynchronization therapy defibrillators referred to jointly as ICDs) reduce rates of sudden cardiac death in patients with cardiovascular disease. However, shocks from ICDs may be associated with healthcare resource use (HCRU) and costs. The aim of this study was to estimate the costs associated with both appropriate and inappropriate shocks from ICDs. Methods: Patients with appropriate and inappropriate shocks from ICDs were identified via CareLink data from Liverpool Heart and Chest Hospital between March 2017 and March 2019. The devices were SmartShock activated, with anti-tachycardia pacing. Costs were estimated according to the dominant episode of healthcare, from an NHS payer perspective. Results: There were 2445 patients on the CareLink system with ICDs. Over the two-year period, HCRU data from 143 shock episodes among 112 patients were reported. The total cost for all shocks was £252,552 with mean costs of £1608 and £2795 for appropriate and inappropriate shocks respectively. There was substantial variation in HCRU between shock episodes. Conclusion: While there was a low rate of inappropriate shocks from ICDs, there were still substantial HCRU and costs incurred. In this study, the specific HCRU was not costed independently, meaning the costs reported are likely to be a conservative estimate. Whilst every attempt to reduce shocks should be made, appropriate shocks cannot be avoided. Strategies to reduce the incidence of inappropriate and unnecessary shocks should be implemented to reduce overall health care costs associated with ICDs.

A multidisciplinary approach to re-intervention in an Ebstein patient: a case report.

Background: Ebstein's anomaly is a rare condition due to incomplete delamination of the tricuspid valve (TV) leaflets with downward displacement of the proximal leaflet attachments. It is associated with a smaller functional right ventricle (RV) and tricuspid regurgitation (TR) that is typically treated with TV replacement or repair. However, future re-intervention poses challenges. We describe a multidisciplinary team approach to re-intervention in a pacing-dependant Ebstein patient with severe bioprosthetic TV regurgitation. Case summary: A 49-year-old female patient underwent bioprosthetic TV replacement for severe TR in Ebstein's. Post-operatively, she developed complete atrioventricular (AV) block necessitating the implantation of a permanent pacemaker which included a coronary sinus (CS) lead as the ventricular lead. Five years later, she presented with syncope due to a failing ventricular pacing lead, and a new RV lead was positioned across the TV bioprosthesis due to the lack of CS options. Two years later, she presented with breathlessness and lethargy with severe TR identified on transthoracic echocardiography. She successfully underwent a percutaneous leadless pacemaker implant, extraction of existing pacing system, and implantation of valve-in-valve TV. Discussion: Patients with Ebstein's anomaly typically undergo TV repair or replacement. Following surgical intervention, owing to the anatomical location, patients can develop AV block requiring a pacemaker. Pacemaker implantation may involve a CS lead to avoid placing a lead across the new TV in efforts to avoid lead induced TR. Over time, these patients not uncommonly require re-intervention that can be challenging especially in pacing-dependant patients with leads across the TV.

Statistical bioprocess optimization for enhanced production of a thermo alkalophilic polygalacturonase (PGase) from Pseudomonas sp. 13156349 using solid substrate fermentation (SSF).

In this study, a polygalacturonase (PGase) producing bacterial strain was isolated and identified as Pseudomonas sp. 13159349 from fruit market soils, and TLC analysis confirmed its pectinolytic activity. Additionally, SSF, Plackett-Burman design (PB), and response surface methodology (RSM) were used to optimize the production of this thermostable and alkalophilic PGase. Wheat bran demonstrated the highest activity (60.13 ± 3.39 U/gm) among the various agricultural wastes used as solid substrates. To further enhance the enzyme production, statistical optimization of media components was investigated using the PB design. Among the 11 variables tested, pH (p < 0.0001), inoculum size (p < 0.0001), incubation time (p < 0.0001), and temperature (p < 0.0041) were found to have a positive effect on the production. The interaction and concentration of the selected factors were examined by RSM, which demonstrated the optimal conditions for maximum production (315.65 U/gm) of the enzyme using wheat bran as the solid substrate were pH 10.5, 61-66 h of incubation, and 6-7.5% inoculum size. The model was highly significant, with a p-value of <0.0001, an F-value of 95.33, and a low CV of 2.31. The RSM model was validated by a laboratory-scale experiment showing 30600 ± 400.32 U/100 gm PGase activity. Thus, SSF and the statistical design of media components resulted in a significant 5.2-fold increase in PGase output solely by using agro waste and optimizing the physical parameters, making this a highly cost-effective bioprocess.

Early Lead Extraction for Infected Implanted Cardiac Electronic Devices: JACC Review Topic of the Week.

Infection remains a serious complication associated with the cardiac implantable electronic devices (CIEDs), leading to substantial clinical and economic burden globally. This review assesses the burden of cardiac implantable electronic device infection (CIED-I), evidence for treatment recommendations, barriers to early diagnosis and appropriate therapy, and potential solutions. Multiple clinical practice guidelines recommended complete system and lead removal for CIED-I when appropriate. CIED extraction for infection has been consistently reported with high success, low complication, and very low mortality rates. Complete and early extraction was associated with significantly better clinical and economic outcome compared with no or late extraction. However, significant gaps in knowledge and poor recommendation compliance have been reported. Barriers to optimal management may include diagnostic delay, knowledge gaps, and limited access to expertise. A multipronged approach, including education of all stakeholders, a CIED-I alert system, and improving access to experts, could help bring paradigm shift in the treatment of this serious condition.

"The other side of the table ': Early career gynaecological oncologists' transition from trainee to trainer.

BACKGROUND: The transition to consultant practice represents an important transition from the role of trainee to trainer. We used the theoretical framework of Threshold Concepts to better understand this transition by analysing data from a broader qualitative study examining the experience of early career Certified Gynaecological Oncologists (CGOs) in Australia and New Zealand. MATERIALS AND METHODS: Semi-structured interviews were conducted with CGOs of <5 years consultant experience. Transcripts were analysed using reflexive thematic analysis, sensitised by the theoretical framework of Threshold Concepts. RESULTS: Seven early career CGOs were interviewed. Analysis resulted in the construction of five main themes related to the trainer role, each demonstrating characteristics of Threshold Concepts: 'Part of becoming and being a consultant'; 'Managing complex work environments and training responsibilities'; 'Optimising near peer relationships'; 'Recency informing evolution of training'; and "'Being responsible and letting go…' - the next transition." DISCUSSION: The themes offer insights into the areas of the transition to trainer that are troublesome, the impact of negotiating these challenges on professional identity formation, and the strategies used by CGOs to negotiate them. Using the lens of Threshold Concepts, these experiences can be normalised, and supported through efforts to facilitate the development of skills in reflection, feedback, coaching and mentorship.

New atrial arrhythmia occurrence in single chamber implantable cardioverter defibrillator patients: A real-world investigation.

INTRODUCTION: A current limitation of single chamber implantable cardioverter defibrillators (ICDs) is the lack of an atrial lead to reliably detect atrial fibrillation (AF) episodes. A novel ventricular based atrial fibrillation (VBAF) detection algorithm was created for single chamber ICDs to assess R-R variability for detection of AF. METHODS: Patients implanted with Visia AF™ ICDs were prospectively enrolled in the Medtronic Product Surveillance Registry from December 15, 2015 to January 23, 2019 and followed with at least 30 days of monitoring with the algorithm. Time to device-detected daily burden of AF ≥ 6 min, ≥6 h, and ≥23 h were reported. Clinical actions after device-detected AF were recorded. RESULTS: A total of 291 patients were enrolled with a mean follow-up of 22.5 ± 7.9 months. Of these, 212 (73%) had no prior history of AF at device implant. However, 38% of these individuals had AF detected with the VBAF algorithm with daily burden of ≥6 min within two years of implant. In these 80 patients with newly detected AF by their ICD, 23 (29%) had a confirmed clinical diagnosis of AF by their provider. Of patients with a clinical diagnosis of AF, nine (39%) were newly placed on anticoagulation, including five of five (100%) patients having a burden >23 h. CONCLUSIONS: Continuous AF monitoring with the new VBAF algorithm permits early identification and actionable treatment for patients with undiagnosed AF that may improve patient outcomes.

UK Expert Consensus Statement for the Optimal Use and Clinical Utility of Leadless Pacing Systems on Behalf of the British Heart Rhythm Society.

Pacemakers are a key technology in the treatment of bradyarrhythmias. Leadless pacemakers (LP) were introduced to address limitations of transvenous devices. However, guidelines and other restrictions have led to LPs becoming niche products. The aim of this consensus statement was to determine the strength of opinion of UK implantation experts as to how LPs can be more optimally used. Using a modified Delphi approach, a panel of LP experts developed 36 statements that were used to form a survey that was distributed to LP implanters in the UK. Stopping criteria included a 3-month window for response, a minimum 25% response rate and at least 75% of statements achieving the threshold for consensus (agreed at 66%). In all, 31 of 36 statements reached consensus, and 23 of these achieved ≥90% agreement. Five statements did not achieve consensus. On the basis of these results, seven recommendations were proposed. The implementation of these recommendations may increase the use of LPs, with the aim of improving patient outcomes.

Multispecialty multidisciplinary input into comorbidities along with treatment optimisation in heart failure reduces hospitalisation and clinic attendance.

AIMS: Heart failure (HF) is associated with comorbidities which independently influence treatment response and outcomes. This retrospective observational study (January 2020-June 2021) analysed the impact of monthly HF multispecialty multidisciplinary team (MDT) meetings to address management of HF comorbidities and thereby on provision, cost of care and HF outcomes. METHODS: Patients acted as their own controls, with outcomes compared for equal periods (for each patient) pre (HF MDT) versus post-MDT (multispecialty) meeting. The multispecialty MDT comprised HF cardiologists (primary, secondary, tertiary care), HF nurses, nephrologist, endocrinologist, palliative care, chest physician, pharmacist, clinical pharmacologist and geriatrician. Outcome measures were (1) all-cause hospitalisations, (2) outpatient clinic attendances and (3) cost. RESULTS: 334 patients (mean age 72.5±11 years) were discussed virtually through MDT meetings and follow-up duration was 13.9±4 months. Mean age-adjusted Charlson Comorbidity Index was 7.6±2.1 and Rockwood Frailty Score 5.5±1.6. Multispecialty interventions included optimising diabetes therapy (haemoglobin A1c-HbA1c pre-MDT 68±11 mmol/mol vs post-MDT 61±9 mmol/mol; p<0.001), deprescribing to reduce anticholinergic burden (pre-MDT 1.85±0.4 vs 1.5±0.3 post-MDT; p<0.001), initiation of renin-angiotensin aldosterone system inhibitors in HF with reduced ejection fraction (HFrEF) with advanced chronic kidney disease (9% pre vs 71% post-MDT; p<0.001). Other interventions included potassium binders, treatment of anaemia, falls assessment, management of chest conditions, day-case ascitic, pleural drains and palliative support. Total cost of funding monthly multispecialty meetings was £32 400 and resultant 64 clinic appointments cost £9600. The post-MDT study period was associated with reduction in 481 clinic appointments (cost saving £72150) and reduced all-cause hospitalisations (pre-MDT 1.1±0.4 vs 0.6±0.1 post-MDT; p<0.001), reduction of 1586 hospital bed-days and cost savings of £634 400. Total cost saving to the healthcare system was £664 550. CONCLUSION: HF multispecialty virtual MDT model provides integrated, holistic care across all healthcare tiers for management of HF and associated comorbidities. This approach is associated with reduced clinic attendances and all-cause hospitalisations, leading to significant cost savings.

Collaborative centralization of gynaecological cancer care.

PURPOSE OF REVIEW: To discuss the benefits of centralization of gynaecological cancer care on patients and the healthcare system and how to overcome its barriers. RECENT FINDINGS: Evidence demonstrates that adherence to clinical practice management guidelines is more likely; the risk of adverse events is lower; survival is improved; in young women fertility preservation is higher; and cost effectiveness is higher; in systems that employ centralized care for women with gynaecological cancer. Barriers to the uptake of centralized models include knowledge, attitude as well as deficient systems and processes, including a lack of governance and leadership. Collaborative centralization refers to a model that sees both elements (centralization and treatment closer to home) utilized at the patient level that addresses some of the barriers of centralized gynaecological cancer care. SUMMARY: Evidence supports centralized gynaecological cancer care, as it results in reduced risks of adverse events, improved survival and higher fertility rates at lower cost to funders. Collaborative centralization is a process that considers both the value of centralization and collaboration amongst healthcare professionals at primary, secondary and tertiary levels of healthcare to benefit patient outcomes.
