Abstract:
Objective: To explore why transplant patients experience unexpected mild-to-moderate distress and what support they may need.
Design: Qualitative study using individual in-depth interviews. Setting Four National Health Service (NHS) Trusts in the Midlands, UK. Participants Fifteen renal transplant patients meeting the criteria for mild-to-moderate distress from their responses to emotion thermometers. Main outcome measures Identification of the reasons for distress and support options acceptable to renal transplant patients.
Results: Three themes were interpreted from the data: I am living with a "foreign body" inside me', why am I distressed?' and different patients want different support'. Following their transplant, participants felt that they should be happy and content, but this was often not the case. They described a range of feelings about their transplant, such as uncertainty about the lifespan of their new kidney, fear of transplant failure or fear of the donor having health conditions that may transfer to them. A few experienced survivors' guilt when others they had met at the dialysis unit had not received a transplant or because someone had died to enable them to receive the transplant. No longer having regular contact with the renal unit made participants feel isolated. Some participants did not initially attribute the source of their distress to their transplant. Participants' preferred support for their distress and their preferences about who should deliver it varied from peer support to seeing a psychologist.
Conclusions: Raising the issue of post-transplant mild-to-moderate distress with patients and encouraging them to think about and plan coping strategies pretransplant may prove beneficial for the patient and healthcare provider. Patients should be able to choose from a variety of support options.

Abstract:
OBJECTIVE: In the United Kingdom, guidelines from the Royal College of Pathologists (RCPath) facilitate consistent and reproducible reporting and classification of fine needle aspiration cytology (FNAC) thyroid specimens. The aim was to audit our department against RCPath guidelines to refine and improve our reporting process.
METHOD(S): Two-cycle retrospective observational audit of all patients undergoing thyroid FNAC over a two-year period (one year for each cycle). Final histology was correlated. The positive predictive value (PPV) for malignant neoplastic lesions was calculated; for Thy1, Thy1c, Thy2 and Thy2c all cases without final histology were assumed to be benign, while for Thy3a, Thy3f, Thy4 and Thy5 samples the PPV calculation was based only on those cytology samples with corresponding histology. 'False positive' and 'false negative' cases were reviewed.
RESULT(S): 288 cytology samples were included in the first cycle; 96 (33.3%) had corresponding histology. 287 samples were included in the second cycle; 119 (41.5%) had follow-up histology. The rate of non-diagnostic samples (Thy1/1c) decreased from 39.6% to 30.0%. The PPV for malignant neoplastic lesions was Thy1/1c 2.6%, Thy2/2c 0.0%, Thy3a 40.0%, Thy3f 19.4%, Thy4 75.0%, Thy5 100.0% (first cycle); Thy1/1c 4.7%, Thy2/2c 0.7%, Thy3a 13.3%, Thy3f, 7.7%, Thy4, 50.0%, Thy5 100.0% (second cycle).
CONCLUSION(S): Our department was able to reduce the rate of non-diagnostic FNAC samples and improve the diagnostic accuracy of FNAC. Auditing local outcomes helps refine and improve the reporting process. Review of 'false positive' and 'false negative' cases helps examine potential pitfalls of cytology.

Abstract:
Background: Achilles tendon rupture leads to weakness of ankle plantarflexion. Treatment of Achilles tendon rupture should aim to restore function while minimizing weakness and complications of management. Purpose: To determine the influence of factors (age, sex, body mass index [BMI], weight, time from injury to operative repair, and tightness of repair) in the initial surgical management of patients after an acute Achilles tendon rupture on 12-month functional outcome assessment after percutaneous and minimally invasive repair. Study Design: Cohort study; Level of evidence, 3. Methods: From May 2012 to January 2018, patients sustaining an Achilles tendon rupture receiving operative repair were prospectively evaluated. Tightness of repair was quantified using the intraoperative Achilles tendon resting angle (ATRA). Heel-rise height index (HRHI) was used as the primary 12-month outcome variable. Secondary outcome measures included Achilles tendon total rupture score (ATRS) and Tegner score. Stepwise multiple regression was used to create a model to predict 12-month HRHI. Results: A total of 122 patients met the inclusion criteria for data analysis (mean ± SD age, 44.1 ± 10.8 years; 78% male; mean ± SD BMI, 28.1 ± 4.3 kg/m2). The elapsed time to surgery was 6.5 ± 4.0 days. At 12-month follow-up, patients had an HRHI of 82% ± 16% and performed 82% ± 17% of repetitions compared with the noninjured side. Participants had a mean ATRS of 87 ± 15 and a median Tegner score of 5 (range, 1-9), with a reduction in Tegner score of 2 from preinjury levels. The relative ATRA at 12 months was –4.8° ± 3.9°. Multiple regression identified younger age (B = ±0.006; P <.001) and greater intraoperative ATRA (B = 0.005; P =.053) as predictors of more symmetrical 12-month HRHI (R 2 = 0.19; P <.001; n = 120). Conclusion: Age was found to be the strongest predictor of outcome after Achilles tendon rupture. The most important modifiable risk factor was the tightness of repair. It is recommended that repair be performed as tight as possible to optimize heel-rise height 1 year after Achilles tendon rupture and possibly to reduce tendon elongation.

Practice Nursing; Apr 2020; vol. 31 (no. 4); p. 148-154

Abstract:
Individuals with diabetes may wish to fast during the holy month of Ramadan. David Morris provides an overview of the key considerations for practice nurses helping people with diabetes to manage their condition Ramadan is the holiest month of the Islamic calendar, during which healthy adult Muslims fast. Vulnerable people with diabetes can be exempted from fasting during Ramadan; however, many Muslims with diabetes feel strongly committed to observing Ramadan. The adoption of fasting together with alteration of mealtimes, sleeping arrangements and exercise, places physiological demands on the individual that are likely to be greater in those with diabetes. Health professionals involved in the care of these patients need to offer timely advice on the risks associated with fasting in those with diabetes and, where fasting is planned, support and empower these individuals.

Abstract:
Perioperative tranexamic acid use is a popular choice among many surgeons for reducing surgical blood loss and its sequelae. While there is evidence in the literature that tranexamic acid use is effective in reducing blood loss in surgery for patients with hip fractures, there is less information on whether it leads to thromboembolic complications. We undertook a retrospective study in patients with hip fractures at two local hospitals to investigate if there was an increased risk of venous thromboembolism in patients who received tranexamic acid, and whether it reduced perioperative blood loss and the need for transfusion. We found that tranexamic acid used in patients undergoing hip fracture surgery reduced the drop in postoperative haemoglobin and the need for postoperative blood transfusion but was not associated with an increased risk of venous thromboembolism.

Abstract:
Background Severe anaemia is a major cause of morbidity and mortality in HIV-infected adults living in resource-limited countries. Comprehensive data on the aetiology are lacking but are needed to improve outcomes. Methods HIV-infected adults with severe (haemoglobin <=70g/l) or very severe anaemia (haemoglobin <= 50 g/l) were recruited at Queen Elizabeth Central Hospital, Blantyre, Malawi. Fifteen potential causes and associations with anaemia severity and mortality were explored. Results 199 patients were enrolled: 42.2% had very severe anaemia and 45.7% were on ART. More than two potential causes for anaemia were present in 94% of the patients including iron deficiency (55.3%), underweight (BMI<20: 49.7%), TB infection (41.2%) and unsuppressed HIV infection (viral load >1000 copies/ml) (73.9%). EBV/CMV co-infection (16.5%) was associated with very severe anaemia (OR 2.8 95% CI 1.1-6.9). Overall mortality was high (53%; 100/199) with a median time to death of 17.5 days (IQR 6-55) days. Death was associated with folate deficiency (HR 2.2; 95% CI 1.2-3.8) and end stage renal disease (HR 3.2; 95% CI 1.6-6.2). Conclusion Mortality among severely anaemic HIV-infected adults is strikingly high. Clinicians should be aware of the urgent need for a multifactorial approach including starting or optimising HIV treatment, considering TB treatment, nutritional support and optimising renal management.

Abstract:
CONTEXT: Patients with adrenal insufficiency require increased hydrocortisone cover during major stress to avoid life-threatening adrenal crisis. However, current treatment recommendations are not evidence-based. OBJECTIVE(S): To identify the most appropriate mode of hydrocortisone delivery in patients with adrenal insufficiency exposed to major stress. DESIGN AND PARTICIPANTS: Cross-sectional study: 122 unstressed healthy subjects and 288 subjects exposed to different stressors (major trauma [N=83], sepsis [N=100], and combat stress [N=105]). Longitudinal study: 22 patients with preserved adrenal function undergoing elective surgery. Pharmacokinetic study: 10 patients with primary adrenal insufficiency undergoing administration of 200mg hydrocortisone over 24 hours in four different delivery modes (continuous intravenous infusion; six-hourly oral, intramuscular or intravenous bolus administration). MAIN OUTCOME MEASURE: We measured total serum cortisol and cortisone, free serum cortisol and urinary glucocorticoid metabolite excretion by mass spectrometry. Linear pharmacokinetic modelling was used to determine the most appropriate mode and dose of hydrocortisone administration in patients with adrenal insufficiency exposed to major stress. RESULT(S): Serum cortisol was increased in all stress conditions, with the highest values observed in surgery and sepsis. Continuous intravenous hydrocortisone was the only administration mode persistently achieving median cortisol concentrations in the range observed during major stress. Linear pharmacokinetic modelling identified continuous intravenous infusion of 200mg hydrocortisone over 24 hours, preceded by an initial bolus of 50-100mg hydrocortisone, as best suited for maintaining cortisol concentrations in the required range. CONCLUSION(S): Continuous intravenous hydrocortisone infusion should be favored over intermittent bolus administration in the prevention and treatment of adrenal crisis during major stress.

Abstract:
Patients often have difficulty recovering knee extension strength post total knee arthroplasty (TKA), and that may reflect alteration of the mechanics including geometry and rollback kinematics, so the purpose of this work was to explore this by comparing the knee extension torque (KET) of the native knee, TKA and patellofemoral arthroplasty (PFA) in response to quadriceps tension. Eight fresh-frozen knees were mounted in a knee extension rig with quadriceps loading and tibial extension torque measurement. Each knee was subject to four conditions: native knee, PFA, cruciate-retaining (CR) and posterior-stabilized (PS) TKA. The KET was measured from 120degree to 0degree knee flexion. Data were analyzed using one-way ANOVA and post-hoc paired t-tests. The native KET was lowest in terminal extension and 70-100degree flexion, and maximal at 20-30degree flexion. PFA produced the greatest KET (p < 0.008) compared with native, CR- and PS-TKA, at 30-40degree flexion. CR- and PS-TKA had lower KET across 0-50degree flexion (p < 0.001 across 0-30degree), falling to 25% of the native knee KET or the PFA at full extension. PFA had the highest KET in early flexion possibly due to increased trochlear offset and/or preservation of the cruciate mechanism, so PFA may be more beneficial during the functional range of motion. The claimed benefits of PS- over CR-TKA in deep flexion were not detected. Both CR- and PS-TKAs led to lower KET than the native and PFA knee states across 0-50degree flexion. This mechanical effect may help to explain clinical findings of knee extension weakness post-TKA.

Abstract:
With the increasing median age of survival in the UK, there is an increased burden on the provision of medical and surgical care to the population. The 2010 National Confidential Enquiry into Patient Outcome and Death report, "An Age Old Problem," emphasizes the early involvement of surgical and geriatric consultant input to improve perioperative care in older patients. This study describes the development of a Geriatric Surgical Liaison Service aimed at providing consultant-led geriatrician support to improve the outcomes of older patients undergoing Emergency Laparotomy (EL). The primary outcome is the reduction in length of stay (LOS) compared to baseline data prior to geriatrician involvement. The service was designed to include one clinical session involving a consultant geriatrician and two and a half days with a junior doctor in a week. Data was collected prospectively from February 2018 till July 2018 for surgical patients aged ≥ 70 years, who underwent EL, had an inpatient stay of more than seven days, and who were diagnosed with delirium or incurred inpatient falls (intervention group). Baseline data, prior to geriatrician involvement, were collected retrospectively for EL patients aged ≥ 70 years from December 2015 until May 2016. Length of stay and 30-day mortality were also compared between the two cohorts undergoing EL. A total of 69 patients were included in the intervention group; 45 patients underwent EL and their mean LOS was 17.5 days, which was reduced from 22.5 days prior to geriatrician involvement (n=57). There was no difference in median length of stay and 30-day mortality between the retrospective baseline group and the intervention groups. In the intervention group, 8.5% of patients had a new medical diagnosis and 26.8% of patients were offered follow-ups. Although statistically not significant (p=0.40), a shorter stay in hospital by five days can potentially have a positive impact on patient outcomes by reducing psychosocial, cognitive, and functional deconditioning. This would also improve patient flow, release capacity, and waiting times and would be of benefit to the financially strained National Health Service (NHS). Overall, our study suggests that a collaborative, consultant-led geriatric service can improve the management of older surgical patients by potentially reducing length of stay, identifying high-risk patients, and facilitating early and appropriate specialty input alongside adequate and required outpatient follow-up.
