Systematic review of survival following liver or lung metastasectomy for metastatic anal squamous cell carcinoma

INTRODUCTION

Metastatic anal squamous cell carcinoma (SCC) carries a poor prognosis and the evidence base for surgical resection of metastases remains limited. The aim of this study was to establish the survival outcomes for patients undergoing metastasectomy for anal SCC.

METHODS

A systematic review was performed using the MEDLINE®, Embase®, Cochrane and PubMed® databases. Studies were considered for inclusion in the review if they involved patients aged >18 years with a diagnosis of stage IV anal SCC who underwent metastasectomy for liver and/or lung metastases. The primary outcome measure was overall survival. Secondary outcome measures were disease free survival, early morbidity according to the Clavien-Dindo classification and quality of life, measured using a validated scoring tool. Risk of bias was assessed with the ROBINS-I (Risk Of Bias In Non-randomised Studies - of Interventions) tool.

RESULTS

There were 10 studies with a total of 98 patients. There was heterogeneity in results reporting, with recurrence free survival the most reported outcome. For all studies reporting on liver metastasectomy, the one-year overall survival rate was 87%. In studies with adequate follow-up reported, the three and five-year overall survival rates were 53% and 38% respectively. Only one study reported on lung metastasectomy patients; the overall median survival was 24 months. None of the studies reported on quality of life measures. The ROBINS-I tool identified a critical risk of bias in six studies, a serious risk in one study and a moderate risk in three studies.

CONCLUSIONS

The evidence base for metastasectomy in metastatic anal SCC is limited. Further information is required to inform future treatment methods and use of a standardised outcomes reporting method is needed to support this.

The empty pelvis syndrome: a core data set from the PelvEx collaborative

BACKGROUND

Empty pelvis syndrome (EPS) is a significant source of morbidity following pelvic exenteration (PE), but is undefined. EPS outcome reporting and descriptors of radicality of PE are inconsistent; therefore, the best approaches for prevention are unknown. To facilitate future research into EPS, the aim of this study is to define a measurable core outcome set, core descriptor set and written definition for EPS. Consensus on strategies to mitigate EPS was also explored.

METHOD

Three-stage consensus methodology was used: longlisting with systematic review, healthcare professional event, patient engagement, and Delphi-piloting; shortlisting with two rounds of modified Delphi; and a confirmatory stage using a modified nominal group technique. This included a selection of measurement instruments, and iterative generation of a written EPS definition.

RESULTS

One hundred and three and 119 participants took part in the modified Delphi and consensus meetings, respectively. This encompassed international patient and healthcare professional representation with multidisciplinary input. Seventy statements were longlisted, seven core outcomes (bowel obstruction, enteroperineal fistula, chronic perineal sinus, infected pelvic collection, bowel obstruction, morbidity from reconstruction, re-intervention, and quality of life), and four core descriptors (magnitude of surgery, radiotherapy-induced damage, methods of reconstruction, and changes in volume of pelvic dead space) reached consensus-where applicable, measurement of these outcomes and descriptors was defined. A written definition for EPS was agreed.

CONCLUSIONS

EPS is an area of unmet research and clinical need. This study provides an agreed definition and core data set for EPS to facilitate further research.

Peritoneal dialysis outcomes in a tertiary-level state hospital in Johannesburg, South Africa: Ethnicity and HIV co-infection do not increase risk of peritonitis or discontinuation

BACKGROUND

Peritoneal dialysis (PD) is a valuable means to increase access to kidney replacement therapy in South Africa (SA). An increased rate of modality discontinuation related to an increased risk of peritonitis in patients of black African ethnicity, in those with diabetes and in those living with HIV has previously been suggested, which may lead to hesitancy in adoption of 'PD first' programmes.

OBJECTIVES

To analyse the safety of a PD-first programme in terms of 5-year peritonitis risk and patient and modality survival at the outpatient PD unit at Helen Joseph Hospital, Johannesburg.

METHODS

After exclusions, clinical data from 120 patients were extracted for analysis. The effects of patient age at PD initiation, ethnicity, gender, diabetes mellitus and HIV infection on patient and modality survival and peritonitis risk were analysed using Cox proportional hazards modelling and logistic regression analysis. Five-year technique and patient Kaplan-Meier survival curves for peritonitis and comorbidity groups were compared using the Cox-Mantel test. The Mann-Whitney U-test and Fisher's exact test were used to compare continuous and categorical variables where appropriate.

RESULTS

Five-year patient survival was 49.9%. Black African ethnicity was associated with reduced mortality hazard (hazard ratio (HR) 0.33; 95% confidence interval (CI) 0.15 - 0.71; p=0.004), and patients with diabetes had poorer 5-year survival (19.1%; p=0.097). Modality survival at 5 years was 48.1%. Neither Black African ethnicity nor HIV infection increased the risk of PD discontinuation. Peritonitis was associated with increased modality failure (HR 2.99; 95% CI 1.31 - 6.87; p=0.009). Black African ethnicity did not increase the risk of peritonitis. HIV was not independently associated with an increased risk of peritonitis. Patient and PD survival were generally similar to other contemporaneous cohorts, and the peritonitis rate in this study was within the International Society for Peritoneal Dialysis acceptable range.

CONCLUSION

PD is a safe and appropriate therapy in a low socioeconomic setting with a high prevalence of HIV infection. Consideration of home circumstances and training in sterile technique reduce peritonitis risk and improve PD modality survival. Patients with diabetes may be at risk of poorer outcomes on PD.

The multi-ligament ankle fracture: Epidemiology, key anatomical findings and fixation strategies in unstable open injuries

Background

Ankle fracture surgery has traditionally focussed on restoration of bony anatomy, with fixation of the malleoli and syndesmotic stabilisation where applicable. However, high energy open fracture-dislocations can also result in periosteal stripping of the stabilising capsuloligamentous attachments. As such, restoration of osseous anatomy alone may not result in sufficient articular stability.

Objectives

In this series from a level 1 trauma centre, we report a subset of highly unstable open ankle fractures with combined capsuloligamentous injuries, in which restoration of osseous anatomy did not result in a stable joint. Supplementary soft tissue reconstruction and other stabilisation techniques were required.

Methods

Retrospective case series of eligible patients from a level 1 trauma centre. Inclusion criteria were open ankle fractures with tibial extrusion (AO 44) and persistent instability post-bony fixation, age over 18 years and non-diabetic. Analysis of injury pattern, mechanism, pathological anatomy, soft tissue and orthopaedic reconstruction methods was performed.

Results

16 patients were identified during the study period who met the eligibility criteria, out of 95 open ankle fractures treated between January 2017-December 2020. Most patients were under 65 (n = 13; 81.3%) and sustained combined or isolated injuries of the deltoid ligament, anterior capsule, lateral ligament complex (ATFL±CFL) and tibialis posterior retinaculum. The commonest injury pattern was tibial extrusion via a medial soft tissue defect with deltoid ligament and anteromedial capsule rupture. Associated syndesmotic instability and fixation was common (n = 10; 62.5%). Supplementary stabilisation methods to standard bony fixation included capsuloligamentous reconstruction or repair, "ORIF+" external fixation, or conversion to primary fusion or hindfoot nail. Six patients required either local or free flap soft tissue coverage.

Conclusions

A subset of up to 20% of open ankle fractures require supplementary fixation beyond anatomical restoration of the bony anatomy due to persistent ligamentous instability. They are associated with capsuloligamentous and syndesmotic disruption, more commonly affecting the medial structures. These rare injuries can be defined as multi-ligament ankle fractures. Surgeons should be aware of this subset and be able to recognise where supplementary stabilisation strategies are required.

Assessing and managing open fractures: a systematic approach

Open fractures are complex injuries strongly associated with high-energy trauma. Assessment should include the mechanism and place of injury, timing, associated injuries and comorbidities. The initial management of these fractures, whether in the prehospital setting or emergency department, must include the following in a prompt manner: administration of antibiotics and tetanus prophylaxis, photography, reduction or re-alignment, wound coverage and splintage. Imaging includes plain X-rays and a computed tomography trauma scan, as well as an angiogram if vessel damage is suspected. Collectively, the energy of the mechanism of injury, with the level of contamination, potential for compartment syndrome and vascular damage, determines the operative urgency. Operative management can be a one- or two-stage procedure, because definitive internal skeletal fixation should only be attempted if soft tissue coverage can occur during the same operation. Ideally, all open fractures should be closed within 72 hours. This article explores the evidence for current best practice.

The household economic burden of drug-susceptible TB diagnosis and treatment in The Gambia

OBJECTIVE: To determine the costs and catastrophic costs incurred by drug-susceptible (DS) pulmonary TB patients in The Gambia.METHODS: This observational study collected cost and socio-economic data using a micro-costing approach from the household perspective from 244 adult DS-TB patients with pulmonary TB receiving treatment through the national treatment programme in The Gambia. We used data collected between 2017 and 2020 using an adapted version of the WHO generic patient cost survey instrument to estimate costs and the proportion of patients experiencing catastrophic costs (≥20% of household income).RESULTS: The mean total cost of the TB episode was $104.11 (2018 USD). Direct costs were highest before treatment ($22.93). Indirect costs accounted for over 50% of the entire episode costs. Using different income estimation approaches and catastrophic cost thresholds, 0.4-75% of participants encountered catastrophic costs, showing the variability of results given the different assumptions we utilised.CONCLUSIONS: We show that despite the benefits of free TB care and treatment, DS-TB patients still incur substantial direct and indirect costs, and cases of impoverishing expenditure varied vastly depending on the income estimation approaches used.

Minimum standards of pelvic exenterative practice: PelvEx Collaborative guideline

This document outlines the important aspects of caring for patients who have been diagnosed with advanced pelvic cancer. It is primarily aimed at those who are establishing a service that adequately caters to this patient group. The relevant literature has been summarized and an attempt made to simplify the approach to management of these complex cases.

Age and the anaesthetist: considerations for the individual anaesthetist and workforce planning: Guidelines about the ageing anaesthetic workforce from the Association of Anaesthetists: Guidelines for the ageing anaesthetic workforce from the Association of Anaesthetists

There is clear evidence of a growing workforce gap and this is compounded by demographic data that show the current workforce is ageing. Within the current workforce, more doctors are taking voluntary early retirement and the loss of these experienced clinicians from departments can have wide-ranging effects. Older doctors are at risk of age-related health problems (e.g. sight, musculoskeletal, menopause) and are more susceptible to the effects of fatigue, which may increase the risk of error and or complaint. The purpose of this working party and advocacy campaign was to address concerns over the number of consultants retiring at the earliest opportunity and whether a different approach could extend the working career of consultant anaesthetists and SAS doctors. This could be viewed as 'pacing your career'. The earlier this is considered in a clinician's career the greater the potential mitigation on individuals.

Hindfoot Nail or Protibial Screw Fixation for Ankle Fracture: A Multi-Centre Study

Category:

Ankle; Trauma

Introduction/Purpose:

Multi-centre assessment of utilisation and outcomes of hindfoot intramedullary fixation (HFN) or fibula pro-tibial screw fixation (PTS) in complex ankle fractures.

Methods:

From January 2020 - June 2021, demographic data, co-morbidities, was collected on all patients undergoing HFN or PTS for an AO44 ankle fracture at three Major Trauma Centre's (MTC's) in the UK. Outcomes of interest included post-operative complications, Charlson-Co-morbidity-Index-Score (CCIS), weight-bearing status, peri-operative information, soft tissue management and post-operative complications were recorded, Radiographs were assessed for metalwork breakage and anatomical reduction (Pettrone Criteria).

Results:

77 patients were identified; 59 underwent HFN and 18 had PTS fixation. The mean age differed between techniques (80+-11.4 [HFN] vs. 66+-19.8 [PTS]) (p<0.001) and 10-year survival favoured patients undergoing PTS (30+-31.6% in the [HFN] and 55+-37.6%[PTS] (p<0.004). 17 (29%) HFN patients had diabetes compared with 7 (39%) PTS patients. 36 (61%) HFN's were open fractures, 7 (39%) PTS's were open fractures, differences in outcomes between primary closure/shortening/joint preparation and combined ortho-plastic management were noted in the HFN group.Time to full weight bearing was reduced in HFN vs. PTS (2.1+-3.1 vs. 8.0+-5.0) (p<0.001), only a minority of patients were allowed to WB immediately. 12 (27%) of patients with open fractures had post-operative complications compared with 5 (15%) of closed fractures. The mean Pettrone score for HFN was 1.3+-1.6 compared with 3.7+-0.6 for PTS, subgroup analysis showed Pettrone scores for open fractures treated with a HFN worsened(0.9 vs 2.3) (p=0.007).

Conclusion:

Comparing functional and outcome rates between the 2 techniques, PTS provides stable fixation, and a lower overall complication rates, with better radiological outcomes and expected survival. However, HFN is performed in frailer patients, with co-morbidities where early weight-bearing may be beneficial, accepting limited functionality and higher complication rate. Even though both techniques are designed for early mobility in the appropriate person this is not always realised, thus further studies are required to characterise which patients benefit most from each surgical technique.

Incisional hernia following colorectal cancer surgery according to suture technique: Hughes Abdominal Repair Randomized Trial (HART)

BACKGROUND

Incisional hernias cause morbidity and may require further surgery. HART (Hughes Abdominal Repair Trial) assessed the effect of an alternative suture method on the incidence of incisional hernia following colorectal cancer surgery.

METHODS

A pragmatic multicentre single-blind RCT allocated patients undergoing midline incision for colorectal cancer to either Hughes closure (double far-near-near-far sutures of 1 nylon suture at 2-cm intervals along the fascia combined with conventional mass closure) or the surgeon's standard closure. The primary outcome was the incidence of incisional hernia at 1 year assessed by clinical examination. An intention-to-treat analysis was performed.

RESULTS

Between August 2014 and February 2018, 802 patients were randomized to either Hughes closure (401) or the standard mass closure group (401). At 1 year after surgery, 672 patients (83.7 per cent) were included in the primary outcome analysis; 50 of 339 patients (14.8 per cent) in the Hughes group and 57 of 333 (17.1 per cent) in the standard closure group had incisional hernia (OR 0.84, 95 per cent c.i. 0.55 to 1.27; P = 0.402). At 2 years, 78 patients (28.7 per cent) in the Hughes repair group and 84 (31.8 per cent) in the standard closure group had incisional hernia (OR 0.86, 0.59 to 1.25; P = 0.429). Adverse events were similar in the two groups, apart from the rate of surgical-site infection, which was higher in the Hughes group (13.2 versus 7.7 per cent; OR 1.82, 1.14 to 2.91; P = 0.011).

CONCLUSION

The incidence of incisional hernia after colorectal cancer surgery is high. There was no statistical difference in incidence between Hughes closure and mass closure at 1 or 2 years.

Risk-Reducing Salpingo-Oophorectomy and the Use of Hormone Replacement Therapy Below the Age of Natural Menopause: Scientific Impact Paper No. 66 October 2021: Scientific Impact Paper No. 66

This paper deals with the use of hormone replacement therapy (HRT) after the removal of fallopian tubes and ovaries to prevent ovarian cancer in premenopausal high risk women. Some women have an alteration in their genetic code, which makes them more likely to develop ovarian cancer. Two well-known genes which can carry an alteration are the BRCA1 and BRCA2 genes. Examples of other genes associated with an increased risk of ovarian cancer include RAD51C, RAD51D, BRIP1, PALB2 and Lynch syndrome genes. Women with a strong family history of ovarian cancer and/or breast cancer, may also be at increased risk of developing ovarian cancer. Women at increased risk can choose to have an operation to remove the fallopian tubes and ovaries, which is the most effective way to prevent ovarian cancer. This is done after a woman has completed her family. However, removal of ovaries causes early menopause and leads to hot flushes, sweats, mood changes and bone thinning. It can also cause memory problems and increases the risk of heart disease. It may reduce libido or impair sexual function. Guidance on how to care for women following preventative surgery who are experiencing early menopause is needed. HRT is usually advisable for women up to 51 years of age (average age of menopause for women in the UK) who are undergoing early menopause and have not had breast cancer, to minimise the health risks linked to early menopause. For women with a womb, HRT should include estrogen coupled with progestogen to protect against thickening of the lining of the womb (called endometrial hyperplasia). For women without a womb, only estrogen is given. Research suggests that, unlike in older women, HRT for women in early menopause does not increase breast cancer risk, including in those who are BRCA1 and BRCA2 carriers and have preventative surgery. For women with a history of receptor-negative breast cancer, the gynaecologist will liaise with an oncology doctor on a case-by-case basis to help to decide if HRT is safe to use. Women with a history of estrogen receptor-positive breast cancer are not normally offered HRT. A range of other therapies can be used if a woman is unable to take HRT. These include behavioural therapy and non-hormonal medicines. However, these are less effective than HRT. Regular exercise, healthy lifestyle and avoiding symptom triggers are also advised. Whether to undergo surgery to reduce risk or not and its timing can be a complex decision-making process. Women need to be carefully counselled on the pros and cons of both preventative surgery and HRT use so they can make informed decisions and choices.

EP.FRI.42 REBOA associated iatrogenic AV fistula

Aim

To discuss a rarely reported complication of Resuscitative endovascular balloon occlusion of the aorta (REBOA) in a trauma patient with exsanguating haemorrhage.

Case description

A 15 year old male sustained was brought in as a cod Red, following multiple stab injuries to his Rt thigh. A REBOA was inserted via the contralateral Femoral artery on the scene to control the bleeding. Once proximal and distal control was obtained on the Right leg, the REBOA was deflated and removed. The right leg needed an interposition vein graft and ligation of femoral vein. The patient had received 12 units of transfusion.

Post-operative CT-angiogram demonstrated an AV fistula between the Left Profunda femoris artery and Common femoral vein on the side of REBOA insertion. A Duplex scan showed flows of 2600ml/min on duplex and AVF diameter of 2.6mm. It was decided to wait for spontaneously closure as patient underwent rehab. At 6 weeks the AVF flow had reduced to 460ml/min however further expectant management did not lead to spontaneous closure of the AVF and he underwent surgical tie off during his next school holidays 6 months later.

Conclusion

AV fistula formation as a complication of REBOA insertion has not been reported in paediatric population. It highlights the need for a CT angio after surgical stabilisation. These post traumatic AVFs may need surgical repair if it does not spontaneously close in 3-6 month time.

356 An Unfortunate Case of Spinal Injury and Bladder Dysfunction During the Covid-19 Pandemic

There is no doubt that COVID-19 has had a profound impact on every medical and surgical speciality. In the height of the pandemic many non-emergency services were shut down, including dental services, with unexpected consequences. We present a case which highlights the unexpected and indirect consequences of a national lockdown on a Urology patient and discuss learning points.

A 54-year-old male, previously fit and well suffered with a small dental abscess, media outlets were reporting that dental surgeries were closed, and he therefore attempted to drain the abscess himself. The infection spread to his epidural space, causing compression via a collection at L2 and consequently spinal cord injury. This was managed with urgent lumbar decompression and antibiotics.

A specialist functional urology team were involved after his transfer to the tertiary spinal unit 3 months after his first presentation. He was catheterised but suffered with recurrent catheter blockages. Video urodynamics demonstrated a stable bladder with a low-pressure leak point, managed with urethral catheterisation. A repeat video urodynamics demonstrated a loss of compliance and stress incontinence. Unclear as to whether he would regain function rehabilitation techniques are currently being attempted prior for definitive operative management with an artificial sphincter.

This case highlights the indirect impact of COVID-19 on UK urology services, and this has not been widely reported.

965 Complication Rates in Operatively Managed Ankle Fracture/Dislocations - The Effect of Pre-Reduction Imaging and Compliance with BOAST 12 Guidance

Aim

The BOAST-12 guidelines for the management of ankle fractures aims to optimise functional recovery and reduce complications. They advise against having radiographs prior to urgent reduction of clinically deformed ankles as it could cause an unacceptable delay to subsequent management. Our study aimed to assess the effect of time to acceptable reduction on the risk of complications and time to definitive reduction.

Method

This was a retrospective observational study of patients with ankle fracture-dislocations between 2013 to 2017 at the Northern General Hospital’s Emergency Department (ED). Information collected from 2 patient groups (with and without pre-reduction radiographs), included patient demographics, time to accepted reduction, number of manipulations, operations, and subsequent complications.

Results

242 patients were identified. Time from arrival in ED to acceptable reduction was significantly longer in patients with pre-reduction radiographs versus patients without (184.5 vs 82 minutes, p &lt; 0.00), but did not increase the overall risk of complications (p = 0.62). Pre-reduction radiographs were associated with insignificantly higher rates of post-traumatic osteoarthritis (p = 0.17) and slightly longer wait time for definitive intervention (1 vs 2 days, p = 0.72). However, this had no relationship with the number of manipulations (p = 0.53).

Conclusions

The use of pre-reduction radiographs significantly increased time to acceptable reduction of ankle fracture-dislocations. However, this was not associated with increased risk of complications or time to definitive management.

P–712 Ovulation induction in type 1 anovulation: a comparative study using gonadotrophins and the GnRH pump

Study question

Is there a difference in treatment outcome between gonadotrophin releasing hormone (GnRH) pump or hMG for women with Type 1 anovulation undergoing ovulation induction?

Summary answer

Treatment with GnRH was more efficient compared to hMG, with fewer number of cycles to pregnancy, fewer days of stimulation and fewer cycle cancellations.

What is known already

Whilst there is a lot of information on ovulation induction in WHO type II anovulation (PCOS), type 1 anovulation is under-represented in research. WHO type 1 anovulation is characterised by low pituitary gonadotrophins and oestradiol. Treatment options used to include induction of ovulation using gonadotrophins (hMG) or the Gonadotrophin hormone releasing hormone (GnRH) pump delivering pulsatile GnRH. Since the withdrawal of GnRH pump, options have become limited. One study reveals that monofollicular cycles are lower and cycle cancellation higher in women with Type 1 anovulation women treated with gonadotrophins. Study design, size, duration: This is a single centre retrospective cohort study. All women with a diagnosis of WHO type 1 anovulation attending the Reproductive Medicine Unit at the University College London Hospital who received ovulation induction treatment using either hMG or GnRH pump between 1993 and 2020 were included in the study

Participants/materials, setting, methods

147 women with WHO type 1 anovulation were included in the study. Diagnosis was based on the presence of primary or secondary amenorrhoea in combination with low gonadotrophins and oestradiol. Demographic and clinical data were obtained by reviewing medical records stored within an electronic database. A total of 599 treatment cycles were identified. Statistical analysis between the groups was performed using the independent T test and chi squared test.

Main results and the role of chance

147 women with WHO type 1 anovulation underwent ovulation induction. hMG was used in 500 cycles (83.5%) and the GnRH pump in 99 cycles (16.5%). Per cycle started the pregnancy rate in the hMG cycles was 107/500 (21.4%) and in the GnRH pump cycles was 19/99 (19.2%) p = 0.36. Cycle cancellation was significantly greater in hMG than GnRH pump cycles (hMG 137/ 500 27.4% vs GnRH pump 17/99 17.2% p = 0.02). Over response was more common in hMG cycles than GnRH pump cycles (66/130 50.8% vs 3/16 18.8% p = 0.01). A total of 363/500 (72.5%) cycles in the hMG and 82/99 (82.8%) cycles in the GnRH pump group reached ovulation. There was no difference in the pregnancy rate after ovulation (hMG 107/363 29.5% vs GnRH pump 19/82 23.2% p = 0.15). The mean number of treatment cycles to achieve pregnancy was significantly fewer with the GnRH pump compared to hMG (1.8 (min 1 – max 3) vs 2.4 ( min 1 – max 8) p = 0.03).The mean days of stimulation required to reach ovulation was also significantly less with the GnRH pump compared to hMG (16.7 (min 8 – max 34) vs 23.4 (min 7 – max 72) p = &lt;0.001).

Limitations, reasons for caution

This is a retrospective cohort study and is reliant on the quality and quantity of the data entry at the time of clinical treatment.

Wider implications of the findings: Ovulation induction for women with type 1 anovulation is now restricted to a single treatment, namely hMG. hMG is not as effective or optimal as GnRH. Reinstating GnRH in routine clinical practice should be promoted to allow more individualised treatment options and prevent the premature need for in vitro fertilisation..

P–384 First trimester pregnancy outcomes after confirmed SARS-CoV–2 infection in the community; a nationwide prospective longitudinal study of 10,000 pregnant women from the COVID–19 pandemic

Study question

Are pregnant women in the community with confirmed diagnosis of SARS-CoV–2 infection, at increased risk of an early miscarriage?

Summary answer

Women diagnosed with COVID–19 in their first trimester were not at increased risk of an early miscarriage. What is known already: In the earliest stages of the pandemic, the Human Fertilisation and Embryology Authority and the European Society of Human Reproduction and Embryology, independently advised against starting assisted reproductive treatments. At the time of this recommendation, among other reasons, there were concerns about the complications of SARS-CoV–2 during pregnancy and the potential for vertical transmission.

We now having growing evidence that pregnant women are at an increased risk of severe illness along with higher rates of preterm births in those with severe acute respiratory syndrome. However, data on the impact of community infections of SARS-CoV–2 in early pregnancy has been sparse.

Study design, size, duration

This is an online survey study undertaken in the UK between May and November 2020. Pregnant women at any stage in their pregnancy were invited to participate in the study. Study participants were asked to complete online surveys at the end of each trimester. 10, 430 women were recruited to take part in the study. Participants/materials, setting, methods: We analysed pregnancy outcomes from women who were under 13 weeks gestation at the time of registration. We compared miscarriage rates among women with a confirmed diagnosis of SARS-CoV–2 infection to healthy controls. Those in the control group had not been diagnosed with or had symptoms of SARS-CoV–2 infection nor did they have any household contacts that were diagnosed with or had symptoms of SARS-CoV–2 infection.

Main results and the role of chance

10, 430 pregnant women were recruited to participate in the study. 2934 were under 13 weeks gestation at the time of registration. The median age was 32.6 [IQR 29.8–35.6]. The median gestational age at registration was 8 weeks [IQR [6–10]. 246 women reported a miscarriage before 13 weeks of gestation. The overall miscarriage rate before 13 weeks of gestation was 8.4% (95% CI 7.3%–9.4%).

68 women reported a confirmed diagnosis of SARS-CoV–2 infection in their first trimester. The overall rate of confirmed SARS-CoV–2 infections in the first trimester was 2.3% (95% CI 1.8–2.9%). 3/68 (4.4%) were asymptomatic. Among those reporting symptoms, the commonest symptoms were fatigue (82%), headache (69%) and loss of smell/taste (69%). Only 38% of those with a confirmed diagnosis reported a fever. None of the 68 women with confirmed diagnosis of SARS-CoV–2 infection were hospitalised.

The rate of miscarriage before 13 weeks of gestation in women who were diagnosed with SARS-CoV–2 infections was not significantly higher compared to healthy controls (11.8% versus 9.3%, p = 0.35). A further 35 women had household contacts with confirmed SARS-CoV–2 infection although they themselves had not been diagnosed. No miscarriages were reported in this group.

Limitations, reasons for caution

None of the 68 patients diagnosed with SARS-CoV–2 were hospitalised. We do not know whether the rate of miscarriage among hospitalised women with SARS-CoV–2 infection is the same as those with community infections.

Wider implications of the findings: The overall rate of miscarriage during the pandemic was not higher than rates occurring outside of the pandemic. The rate of miscarriage among women diagnosed with SARS-CoV–2 infection was not significantly higher compared to healthy controls. This data can be used to counsel women planning a pregnancy during this pandemic

P–592 Safety and effectiveness of follitropin alfa biosimilar to originator follitropin alfa in real-world clinical practice: A Multinational Comparative, Prospective Cohort Study

Study question

Are safety and effectiveness of Ovaleap® (follitropin alfa), and Gonal-f®, comparable in one treatment cycle of ART in routine clinical practice?

Summary answer

Safety in terms of incidence proportions of OHSS and OHSS severity, as well as pregnancy and live birth rates, were similar between Ovaleap® and Gonal-f®.

What is known already

Ovaleap® (Theramex), a r-hFSH, is a biosimilar medicinal product to Gonal-f® (Merck). As a biosimilar, it went through a rigorous series of physio-chemical, in vitro, in vivo tests and confirmatory Phase I and III studies, to demonstrate similarity/equivalence in quality, safety and efficacy to the reference medicinal product, per the European Medicines Agency (EMA) guidelines. Ovaleap® was approved by the EMA in 2013 for use at the same dose and for the same therapeutic indications as Gonal-f®. Further outcome data from a broader patient population on safety and live birth outcomes provides clinically important insights on newly introduced FSH medicines.

Study design, size, duration

SOFIA (Safety of Ovaleap® Follitropin alfa in Infertile women undergoing superovulation for Assisted reproductive technologies) was a multi-national, comparative, non-interventional, prospective cohort study. The study was performed at 56 centers specializing in ART from six European countries, (Belgium, France, Germany, Italy, Spain, and the United Kingdom) from January 2017 to September 2019 and comprised of 817 infertile women undergoing controlled ovarian hyperstimulation in one treatment cycle for ART

Participants/materials, setting, methods

The study population comprised of infertile women undergoing controlled ovarian hyperstimulation for ART, who were administered Ovaleap® or Gonal-f® and were naïve to any FSH containing products. Eligible patients were enrolled at a ratio of approximately 1:1, both within and between countries. They were followed up to 30 days after the last FSH dose administration. Women who had a confirmed clinical pregnancy were followed until the end of the pregnancy or until delivery.

Main results and the role of chance

A total of 408 and 409 women who were administered Ovaleap® or Gonal-f®, respectively, were eligible for analysis. A total of 382 patients (94%) in the Ovaleap® and 390 patients (95%) in the Gonal-f® cohort completed FSH treatment (up to oocyte maturation triggering), respectively. The two cohorts were generally similar with regard to demographic and baseline characteristics. The incidence proportion of OHSS was 5.1% (95% CI: 3.4, 7.7) in the Ovaleap® and 3.2% (95% CI: 1.9, 5.4) in the Gonal-f® cohort. This difference in OHSS incidence proportion between the two cohorts was not statistically significant neither before (p = 0.159) nor after univariate adjustment for each potential confounder (p &gt; 0.05). The incidence proportion of OHSS severity grades was similar in the two treatment groups (3.4% versus 2.0% for Grade I, 1.2% versus 1.0% Grade II, and 0.5% versus 0.2% Grade III, in the Ovaleap® and Gonal-f® cohorts, respectively) and without a significant statistical difference (p = 0.865, for each grade). Among patients who had embryo transfer, clinical pregnancy rates were 33% and 31%, live birth rates 27% and 26% in the Ovaleap® and Gonal-f® cohorts, respectively.

Limitations, reasons for caution

Since treatment was non-randomised, the study may have been susceptible to selection bias. This was addressed at both the design stage, by balancing recruitment to a 1:1 ratio for Ovaleap® and Gonal-f® treatments, and also at the analysis stage in which, a univariate analysis was performed.

Wider implications of the findings: Findings from this first large European prospective comparative real-world SOFIA study demonstrated that effectiveness (pregnancy and delivery rates) and safety (risk and severity of OHSS), were similar between Ovaleap®and Gonal-f® treatments. Ovaleap, a biosimilar r-hFSH is therefore a suitable option for follicular stimulation in routine clinical practice.

Trends in 30-day readmissions following hospitalisation for heart failure by sex, socioeconomic status and ethnicity

BACKGROUND

Reducing the high patient and economic burden of early readmissions after hospitalisation for heart failure (HF) has become a health policy priority of recent years.

METHODS

An observational study linking Hospital Episode Statistics to socioeconomic and death data in England (2002-2018). All first hospitalisations with a primary discharge code for HF were identified. Quasi-poisson models were used to investigate trends in 30-day readmissions by age, sex, socioeconomic status and ethnicity.

FINDINGS

There were 698,983 HF admissions, median age 81 years [IQR 14].In-hospital deaths reduced by 0.7% per annum (pa), whilst additional deaths at 30-days remained stable at 5%. Age adjusted 30-day readmissions (21% overall), increased by 1.4% pa (95% CI 1.3-1.5). Readmissions for HF (6%) and 'other cardiovascular disease (CVD)' (3%) remained stable, but readmissions for non-CVD causes (12%) increased at a rate of 2.6% (2.4-2.7) pa. Proportions were similar by sex but trends diverged by ethnicity. Black groups experienced an increase in readmissions for HF (1.8% pa, interaction-p 0.03) and South Asian groups had more rapidly increasing readmission rates for non-CVD causes (interaction-p 0.04). Non-CVD readmissions were also more prominent in the least (15%; 15-15) compared to the most affluent group (12%; 12-12). Strongest predictors for HF readmission were Black ethnicity and chronic kidney disease, whilst cardiac procedures were protective. For non-CVD readmissions, strongest predictors were non-CVD comorbidities, whilst cardiologist care was protective.

INTERPRETATION

In HF, despite readmission reduction policies, 30-day readmissions have increased, impacting the least affluent and ethnic minority groups the most.

A system dynamics-based scenario analysis of residential solid waste management in Kisumu, Kenya

The problem of solid waste management presents an issue of increasing importance in many low-income settings, including the progressively urbanised context of Kenya. Kisumu County is one such setting with an estimated 500 t of waste generated per day and with less than half of it regularly collected. The open burning and natural decay of solid waste is an important source of greenhouse gas (GHG) emissions and atmospheric pollutants with adverse health consequences. In this paper, we use system dynamics modelling to investigate the expected impact on GHG and PM_2.5 emissions of (i) a waste-to-biogas initiative and (ii) a regulatory ban on the open burning of waste in landfill. We use life tables to estimate the impact on mortality of the reduction in PM_2.5 exposure. Our results indicate that combining these two interventions can generate over 1.1 million tonnes of cumulative savings in GHG emissions by 2035, of which the largest contribution (42%) results from the biogas produced replacing unclean fuels in household cooking. Combining the two interventions is expected to reduce PM_2.5 emissions from the waste and residential sectors by over 30% compared to our baseline scenario by 2035, resulting in at least around 1150 cumulative life years saved over 2021–2035. The contribution and novelty of this study lies in the quantification of a potential waste-to-biogas scenario and its environmental and health impact in Kisumu for the first time.

The effect of COVID-19 lockdown on psychiatric admissions: role of gender

BACKGROUND

The UK went into nationwide lockdown on 24 March 2020, in response to COVID-19. The direct psychiatric effects of this are relatively unknown.

AIMS

We examined whether the first UK lockdown changed the demographics of patients admitted to psychiatric hospitals (to include gender, legality, route of admission and diagnoses), independent of seasonal variation..

METHOD

We conducted an anonymous review of psychiatric admissions aged ≥18 years in the 6-month period after the announcement of the first UK lockdown (March to August 2020), and in the previous year (March to August 2019), in Kent and Medway NHS and Social Care Partnership Trust in-patient facilities. The number of admissions were compared, along with factors that may help to explain the psychological effects of national lockdown.

RESULTS

There was no significant increase in total number of admissions or the gender percentage. However, there was a 11.8% increase in formal sectioning under the Mental Health Act 1983. This increase was sustained and statistically significant across all 6 months. A sustained decrease in admissions via the crisis team was also observed as being statistically significant. Separate diagnoses saw changes in percentage of admissions between March and May. The most statistically significant was schizophrenia admissions for men in April (18.7%), and women in March (18.4%).

CONCLUSIONS

Our findings highlight the effect of COVID-19 on the legal status of psychiatric admissions, and emphasise the importance of having a robust, adaptable and open psychiatric service that caters to the ongoing needs of patients, regardless of government restrictions.

Home Energy Efficiency and Subjective Health in Greater London

The UK has introduced legislation that requires net-zero greenhouse gas emissions to be achieved by 2050. Improving the energy efficiency of homes is a key objective to help reach this target, and the UK government's Clean Growth Strategy aims to get many homes up to an Energy Performance Certificate (EPC) Band of C by 2035. The relationship between home energy-efficiency and occupant health and wellbeing remains an area of ongoing research. This paper explores the nexus between home energy efficiency, energy consumption and self-reported health-an indicator of the general health and wellbeing of the population. We focus on Greater London through secondary data analysis. Energy-efficiency ratings and air infiltration rates of dwellings, derived from EPCs, were aggregated and matched to local area self-reported health and energy consumption data obtained from the Greater London Authority's (GLA) Lower Layer Super Output Area (LSOA) Atlas database. Our regression model indicates that improving the energy efficiency (SAP) rating by 10 points for a typical home may reduce household gas consumption by around 7% (95% CIs: 2%, 14%). Beta regression finds a positive, but not statistically significant association between median SAP rating and the proportion of the population reporting 'good or very good' health when considering all Greater London LSOAs (z score = 0.60, p value = 0.55). A statistically significant positive association is observed however when repeating the analysis for the lowest income quartile LSOAs (z score = 2.03, p value = 0.04). This indicates that the least well-off may benefit most from home energy efficiency programs. A statistically significant positive association is also observed for the relationship between self-reported health and air infiltration rates (z score = 2.62, p value = 0.01). The findings support existing evidence for the predominantly naturally ventilated UK housing stock, suggesting that home energy efficiency measures provide a co-benefit for occupant health provided that adequate air exchange is maintained.

Links between the amount of antipsychotic medication prescribed per population at general practice level, local demographic factors and medication selection

BACKGROUND

Antipsychotic medications are the first-line pharmacological intervention for severe mental illnesses (SMI) such as schizophrenia and other psychoses, while also being used to relieve distress and treat neuropsychiatric symptoms in dementia. Our aim was to examine the factors relating to antipsychotic prescribing in general practices across England and how cost changes in recent years have impacted on antipsychotic prescribing.

METHODS

The study examined over time the prescribing volume and prices paid for antipsychotic medication by agent in primary care. Monthly prescribing in primary care was consolidated over 5 years (2013-2018) and DDD amount from WHO/ATC for each agent was used to convert the amount to total DDD/practice. The defined Daily Dose (DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults.

RESULTS

We included 5750 general practices with practice population > 3000 and with > 30 people on their SMI register. In 2018/19 there were 10,360,865 prescriptions containing 136 million DDD with costs of £110 million at an average cost of £0.81/DDD issued in primary care. In 2017/18 there was a sharp increase in overall prices and they had not reduced to expected levels by the end of the 2018/19 evaluation year. There was a gradual increase in antipsychotic prescribing over 2013-2019 which was not perturbed by the increase in drug price in 2017/18. The strongest positive relation to increased prescribing of antipsychotics came from higher social disadvantage, higher population density (urban), and comorbidities e.g. chronic obstructive pulmonary disease (COPD). Higher % younger and % older populations, northerliness and non-white (Black and Minority Ethnic(BAME)) ethnicity were all independently associated with less antipsychotic prescribing. Higher DDD/general practice population was linked with higher proportion(%) injectable, higher %liquid, higher doses/prescription and higher %zuclopenthixol depot. Less DDD/population was linked with general practices using higher % risperidone and higher spending/dose of antipsychotic.

CONCLUSIONS

The levels of antipsychotic prescribing at general practice level are driven by social factors/comorbidities. We found a link between depot prescriptions with higher antipsychotic DDD and risperidone prescriptions with lower antipsychotic DDD. It is important that all prescribers are aware of these drivers / links.

Exploring the perceptions of emotional distress among couples living with Type 2 diabetes and among diabetes healthcare providers, and consideration of support needs

AIMS

To compare the emotional distress experienced by people with Type 2 diabetes with the perceptions of their partners, and to explore the perceptions of healthcare providers and how these differ from the perceptions and experiences of couples living with Type 2 diabetes regarding their support needs.

METHODS

A purposive sample of people with Type 2 diabetes and their partners was recruited through Diabetes UK media outlets and support groups, while healthcare providers were recruited through hospital and diabetes education teams. Inductive thematic analysis was conducted.

RESULTS

Seven people with Type 2 diabetes and six partners took part in separate semi-structured interviews and seven healthcare providers took part in focus groups. Themes emerged regarding unique psychological struggles for people with Type 2 diabetes: 'sense of restriction'; 'disempowerment'; and 'acceptance of diabetes'. For partners the themes of 'feeling responsible' and 'need for greater involvement' emerged. Common themes arising from people with Type 2 diabetes, partners and healthcare providers highlighted diabetes-related stresses: 'self-care struggles' and 'perceived need for appropriate psychological support'. A key theme drawn from healthcare providers was 'perceived professional barriers to psychological support', which captures concerns related to providing emotional support in clinical practice.

CONCLUSIONS

People with Type 2 diabetes, partners, and healthcare providers share a common understanding of the emotional stresses of living with Type 2 diabetes, but also experience diabetes differently depending on their role and responsibilities. All face barriers that need to be considered to ensure that emotional support in diabetes is meaningful and feasible in routine practice.

Simultaneous pelvic exenteration and liver resection for primary rectal cancer with synchronous liver metastases: results from the PelvEx Collaborative

AIM

At presentation, 15-20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection.

METHOD

Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival.

RESULTS

Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006).

CONCLUSION

Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.
