Abstract:
Background Folliculitis decalvans (FD) is a rare inflammatory disorder predominantly of the scalp that can progress to cicatrical alopecia. Mainstay treatment is antibiotics; however, resolution is difficult, and relapse is common. Only three cases of FD treated with neodymium:yttrium aluminum garnet (Nd:YAG) laser exist in the literature. We present two cases of recalcitrant FD managed with long pulsed Nd:YAG laser and a literature review. Study Design Retrospective case series of two patients with FD treated with long pulsed Nd:YAG laser. Results The first case was a 49-year-old male with Fitzpatrick skin type II. Previous unsuccessful treatment included oral doxycycline and isotretinoin. A course of eight sessions of Nd:YAG laser (CynergyTM, Cynosure) was performed with settings of 50J/cm<inf>2</inf>, 20msec pulse duration, and 10mm spot size. Complete resolution of FD was achieved and remained stable without adjuvant treatment at 6 months post laser. The second case was a 46-year-old male with Fitzpatrick skin type IV with 9-years history of FD. Previously, oral antibiotics (clindamycin, rifampicin, erythromycin, ciprofloxacin) as well as dapsone, intralesional triamcinolone and acitretin treatment was trialled without success. A total of four successful treatments with Nd:YAG laser was completed with settings of 30J/cm<inf>2</inf>, 40msec pulse duration, and 15mm spot size. Treatment is ongoing. Conclusion Our experience of Nd:YAG laser treatment of FD have been positive. All cases from literature report full resolution of FD maintained without adjuvant treatment between 6 months to 1.5 years after final treatment. Treatment with Nd:YAG laser is an option for patients suffering from recalcitrant FD.

Abstract:
Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2-4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes-including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)-in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease.

Results of an audit of the Peristomal Body Profile Assessment Tool (2022)

Type of publication:
Journal article

Author(s):
*Nicola Tonks Natasha Rolls, Kimberly Bain, Paul Russell-Roberts and Mark Bain

Citation:
British Journal of Nursing, December 2022, Vol 31, No 22, S4-S12 (Stoma Care Supplement)

Abstract:
Background: Leakage is the number one concern for people with an ostomy. The 2019 Ostomy Life Study, a global study of more than 5000 ostomates, showed that 92% of people living with a stoma worry about leakage. Getting the right stoma appliance for each patient is key to increasing patient quality of life. Aim: The study was designed to assess the use of the PeristomalBody Profile Assessment Tool in helping choose the most appropriate stoma products for a given patient, decreasing incidents of leakage and peristomal skin complications. Methods: A multi-centre (33 sites, 147 patients) low-interventional clinical investigation was conducted in which the use of the Peristomal BodyProfile Assessment Tool was evaluated as a tool to reduce incidents of leakage, increase peristomal skin health and increase patient quality of life. A focus group of randomised participating clinicians (n=16) was held to explore the audit results. Results: The assessment tool most often took between 2 and 5 minutes to complete. It supported clinicians in selecting the right appliance for each patient, avoiding leakages and preventing associated peristomal skin complications. The assessment tool helped improve the accuracy and quality of documentation in the patients’ medical/nursing notes, increasing the quality and continuity of care. Participants reported that using the assessment tool helped reduce care costs by reducing the need for product changes, supporting product usage and return patient visits. Conclusion: Use of the Peristomal Body Profile Assessment Tool helped clinicians choose the most appropriate stoma appliance the first time, resulting in patients having healthier peristomal skin, fewer leakages, more confidence in their stoma appliance and a higher quality of life.

Abstract:
INTRODUCTION: Workplace-based assessments (WBAs) are intended to maximise learning opportunities in surgical training. There is speculation as to whether mandatory assessments in this form contribute to a tick-box culture. The objective of this review was to investigate surgical trainees' attitudes towards WBAs. METHOD(S): This systematic review of qualitative studies was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement. The literature was searched on the Medline, Embase, PubMed and Web of Science databases on 22 March 2022. RESULT(S): Sixteen studies were included in the review, mostly carried out on users of the Intercollegiate Surgical Curriculum Programme portfolio in the UK. Trainees felt that WBAs were educationally useful, providing opportunity for feedback, but this was overshadowed by a pressure to reach a set annual quota for WBAs and achieve high scores. Other themes included inaccurate recording of WBAs, the role of WBAs as formative or summative assessments, engagement and accessibility of trainers, and lack of time to complete WBAs. CONCLUSION(S): Negative perceptions about WBAs were widespread among surgical trainees despite a recognition of their capacity to facilitate learning. This review supports the recent removal of the annual quota for WBAs in UK surgical training programmes.

Abstract:
Aims: Historically, the preferred procedure for perforated diverticular disease is Hartmann's procedure (Hp). Although reliably achieving source control, it's associated with a high rate of post-operative complications and a stoma which of ten becomes permanent. We reviewed our experience of patients undergoing Hp vs primary anastomosis (PA) for perforated diverticulitis. Method(s): All patients undergoing emergency resectional surgery for perforated diverticulitis between March 2015 and Jan 2021 were identified from The Hospital Episode Statistics (HES) data. Demographics were collected and The patient groups were case matched for age and Charleson Comorbidity Index (CCI), Computed Tomography (CT) appearance and intraoperative contamination data. Post-operative morbidity/mortality data was compared. Result(s): 105 patients were included. 15 patients had PA (without diversion) and 90 Hp. In The PA cohort were10 males, median age 52 (range 27-76). There were no anastomotic leaks. 30-day morbidities were superficial wound dehiscence (1) and early incisional hernia (1). Median post-operative stay was 9 days (range 5-25). Hp control group (age below 76, Charlson score 10and below, Hinchey 1-3 intraoperatively). Included 58 patients, 26 males, median age 60.5 (range 30-76). Median post-operative stay was 10.5 days (range 5-227). 2 patients required re-operation. 5 patients developed wound infections. At the time of the study 18 patients have undergone reversal, 6 are On active waiting-list for reversal. There was a single 30-day mortality (post-discharge). Conclusion(s):We have shown that PA is safe in selected cohort of patients and have identified that over 50% of patients undergoing Hp could have been considered for PA.

Abstract:
Aims: Hypocalcaemia is a common complication after parathyroidectomy for secondary hyperparathyroidism (SHpT) and is of ten The cause of a prolonged hospital stay post operatively. Although there is no current guidance on targets for total parathyroidectomy for SHpT, current guidance recommends a day-case rate of 90% for patients undergoing Surgery for primary hyperparathyroidism. Our centre has developed a safe protocol which allows us to perform total parathyroidectomies as a day-case procedure in patients with SHpT. This protocol, developed in conjunction with The renal physicians, involves giving The patients alpha calcidol pre-operatively for 5 days, to minimise The incidence of hypocalcaemia, and close monitoring of The calcium levels post operatively, to permit safe discharge. Method(s): We carried out a single centre retrospective study on all patients who underwent a total parathyroidectomy for SHpT between February 2005 and May 2021. All The patients received The alpha calcidol regimen pre-operatively. Data on patient baseline characteristics, peri-operative calcium, potassium and PTH levels, length of hospital stay, operative procedure details, hospital readmission and 30-day morbidity were collected. Result(s): 49 patients underwent a total parathyroidectomy during The study period. 67% of patients were discharged on day 0 or on day 1 post-operatively. Reasons for prolonged hospital stay in The remaining patients included refractory hyperkalaemia requiring dialysis, complications secondary to anaesthesia, as well as hypocalcaemia in a few cases. No patients required readmission during The 30-day post-operative period. Conclusion(s): Day-case Surgery for SHpT can be achieved safely with a pre-operative regimen of alpha calcidol and close monitoring of calcium levels post-operatively.

Abstract:
Aims: In many hospitals the availability of operating theatres and access to senior surgical and anaesthetic support diminishes during night hours. Therefore urgent surgery is sometimes postponed until the following morning rather than performed overnight, if judged to be safe. We aim to determine if a delay to laparoscopic appendicectomy in cases of acute appendicitis of over 12 hours, analogous to an overnight delay, is correlated to worse patient outcomes. Our primary outcome was delayed discharge from hospital. Our secondary outcomes were appendicitis severity, conversion, and post-operative complications. Method(s): We undertook a retrospective review of The medical records of patients who underwent laparoscopic appendicectomy at a UK district General hospital between 01/01/2018 and 30/08/2019. For each patient clinical and demographic information; and times of hospital admission, surgery, and discharge; were collected. Delayed discharged was defined as 'time to discharge' >24 hours. Result(s): 506 patients were included. In 144 patients (28.5%) 'time to surgery' was under 12 hours; in 362 patients (71.5%) 'time to surgery' was over 12 hours. 362 patients (71.5%) had a delayed discharge. 303 patients (59.9%) had Simple appendicitis; 143 patients had severe appendicitis (28.3%); 60 patients had a macroscopically normal appendix (11.9%). No statistically significant association between 'time to surgery' and delayed discharge, appendicitis severity, conversion or 30 day re-presentations was observed. Conclusion(s): Time from admission to start of appendicectomy did not affect patient outcomes. Short in-hospital delays to appendicectomy, for example an overnight delay, may be safe in certain patients, taking account of clinical judgement.

Abstract:
The ureteral insertion of a silicone tube was first performed in 1967. A validated ureteral stent symptom questionnaire (USSQ) is used for an objective assessment of patient-reported stent-related symptoms. As the impact of stent diameter on the incidence of stent-related symptoms is unclear, we aimed to perform a systematic review and meta-analysis comparing USSQ reported outcomes when using a 6 Fr diameter ureteric stent, versus smaller diameter stents (4.7-5 Fr) when inserted for ureteric stones. All randomized control trials and comparative studies of 6 Fr versus 4.7-5 Fr ureteric stents were reviewed. The USSQ outcomes were considered as the primary outcome measures while stent migration was considered as a secondary outcome measure. A total of 61 articles were identified of which four studies met the eligibility criteria. There was a statistically significant association between the use of wider (6 Fr) diameter stents and the incidence of urinary symptoms as measured by the urinary index score. Larger stent diameters were associated with a statistically significant increase in the pain index score. There was no statistically significant difference in the scores between the compared stent diameters with regard to work performance score, general health index score, additional problems index score, and stent migration. There were insufficient reported outcomes to perform a meta-analysis of sexual matters index score. Our meta-analysis shows that using smaller diameter ureteric stents is associated with reduced urinary symptoms and patient-reported pain. Other USSQ parameter outcomes are statistically similar in the 6 Fr ureteric stent cohort versus the 4.7-5 Fr ureteric stent cohort. Our meta-analysis was limited due to the limited number of studies and gross heterogeneity of reporting parameters in various studies. We hope a large-scale homogeneous randomized control trial will further shed more insight into the stent symptoms response to stent diameter

Patient experiences of weight loss and eating after bariatric surgery: A Systematic Review and Qualitative Synthesis (2023)

Type of publication:Journal article

Author(s):*Ansari M; Serjeant S

Citation:Journal of Human Nutrition & Dietetics. 36(4):1438-1450, 2023 Aug.

Abstract:Background: An estimated 26% of men and 29% of women in the UK are living with obesity according to recent statistics. Bariatric Surgery (BS) can induce significant weight loss and improve co-morbidity status. However previous studies highlight challenges in maintaining dietary changes and weight loss. This systematic review aimed to investigate patient experiences of weight loss and eating in the first two years following surgery, to provide clinical recommendations to support this group.Methods: Ethical approval was granted by the University. A systematic search was conducted in four databases. Studies were selected according to the predefined eligibility criteria and methodological quality, assessed via the CASP tool. Data were extracted and analysed using a thematic synthesis method. Rigour was enhanced via use of a data extraction tool, a validated method for data synthesis, peer-review and transparent reporting.Results: In total, 507 records were screened; nine studies met the inclusion criteria. The thematic synthesis yielded four, interlinked analytical themes based on 154 patients' experiences: relationship with food, relationship with oneself, relationship with others and unfinished journey. Positive experiences were reported including development of healthy eating behaviours and significant weight loss, improving physical and psychosocial wellbeing. On the other hand, challenges in adjusting to life after surgery were also reported.Conclusions: This study highlighted the need for personalised dietary advice, addressing the psychological aspects of eating. Support should be extended to the family. Ongoing psychological support must be incorporated in the post-surgery care pathway to help patients deal with the negative outcomes of surgery such as excess skin.
