RESUMEN

The COVID-19 pandemic was complicated by the spread of false information leading to what became widely called an "infodemic". The present opinion paper was written by an ad hoc international team united under the European Union of Medical Specialists (UEMS) umbrella and reflects the organizations' effort to contribute to the resolution of these issues, by highlighting and reflecting on them and by suggesting the medical community's necessary activities resulting in the formulation of effective future communication strategies. The importance of physicians' and other health workers' role and mission as educators and leaders in communities in critical situations should be reassessed and upgraded. We need to equip future doctors with strong and sustainable leadership and communication skills through relevant undergraduate and postgraduate education programs, in order that compliance with preventive medical advice is increased. To avoid possible politically and otherwise biased communication in health crises of the future, European nations should establish independent advisory bodies providing evidence-based advice and participate in communication campaigns. Medical and other health professional organizations should build organizational and personal capacities of their members to enable them to reliably inform and adequately educate governments, populations, civic society, employers' and employees' organizations, schools and universities, and other stakeholders.

RESUMEN

OBJECTIVE: To examine risk of malignancy and death in patients with kidney transplant who receive the immunosuppressive drug sirolimus. DESIGN: Systematic review and meta-analysis of individual patient data. DATA SOURCES: Medline, Embase, and the Cochrane Central Register of Controlled Trials from inception to March 2013. ELIGIBILITY: Randomized controlled trials comparing immunosuppressive regimens with and without sirolimus in recipients of kidney or combined pancreatic and renal transplant for which the author was willing to provide individual patient level data. Two reviewers independently screened titles/abstracts and full text reports of potentially eligible trials to identify studies for inclusion. All eligible trials reported data on malignancy or survival. RESULTS: The search yielded 2365 unique citations. Patient level data were available from 5876 patients from 21 randomized trials. Sirolimus was associated with a 40% reduction in the risk of malignancy (adjusted hazard ratio 0.60, 95% confidence interval 0.39 to 0.93) and a 56% reduction in the risk of non-melanoma skin cancer (0.44, 0.30 to 0.63) compared with controls. The most pronounced effect was seen in patients who converted to sirolimus from an established immunosuppressive regimen, resulting in a reduction in risk of malignancy (0.34, 0.28 to 0.41), non-melanoma skin cancer (0.32, 0.24 to 0.42), and other cancers (0.52, 0.38 to 0.69). Sirolimus was associated with an increased risk of death (1.43, 1.21 to 1.71) compared with controls. CONCLUSIONS: Sirolimus was associated with a reduction in the risk of malignancy and non-melanoma skin cancer in transplant recipients. The benefit was most pronounced in patients who converted from an established immunosuppressive regimen to sirolimus. Given the risk of mortality, however, the use of this drug does not seem warranted for most patients with kidney transplant. Further research is needed to determine if different populations, such as those at high risk of cancer, might benefit from sirolimus.

RESUMEN

It is a truth universally acknowledged that there is a problem with general medicine. Physicians have become increasingly specialised over the past 30 years or so, and specialist care has produced increasingly better outcomes for some patients. The patients left behind are looked after by general medicine, where demand is increasing, operational priority within hospitals is low, there is little professional kudos and recruitment is suffering. Three recent reports - Hospitals on the Edge?, the Future Hospital Commission report, and the Shape of Training report - have described the problems, but not articulated compelling solutions. Here, I discuss what is good about general medicine, what is bad and make suggestions for improvement. These involve getting specialities to take responsibility for care of appropriate admissions automatically and without delay, giving general physicians control over the service that they provide, and using well-chosen financial drivers to support movement in the right direction.

RESUMEN

BACKGROUND: Depression in the dialysis population is common, but trajectories of depression symptoms are unknown. PURPOSE: This study aims to (1) examine whether different patterns of depression symptoms exist over the first year of dialysis and (2) to understand if illness perceptions are associated with observed trajectories of depression symptoms. METHOD: Incident dialysis patients (n = 160) completed the Beck Depression Inventory II and the Revised Illness Perception Questionnaire soon after starting dialysis and again at 6 and 12 months. Latent class growth modelling identified distinct groups of depression symptom trajectories. RESULTS: Three depression trajectories were identified: "low-reducing" (62 %), "moderate-increasing" (21.8 %) and "high-reducing" (16.2 %). Higher levels of depression were associated with a poorer understanding of the illness (coherence) and perceptions that kidney failure has severe consequences and a more cyclical timeline. Beliefs that treatment controlled kidney failure decreased over time in patients with increasing depression symptoms. CONCLUSION: Distinct patterns of depression symptoms are associated with illness perceptions. The potential to identify common patterns of depression symptoms may help target treatments at those most likely to benefit.

RESUMEN

There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

RESUMEN

BACKGROUND: The determination of pharmacokinetic parameters requires accurate and reliable bioanalytical methods. Even using highly selective MS/MS, interferences can occur. This paper describes the source of some of these interferences with an example discussed involving the problem of a ketamine interference in a plasma assay. RESULTS: The introduction of field asymmetric waveform ion mobility spectrometry (FAIMS) removed the interference, enhanced signal-to-background and met GLP acceptance criteria. Relative to the non-FAIMS method, assay calibration characteristics were improved. The FAIMS source gave optimal performance following the introduction of a split in order to reduce the inlet flow to approximately 0.4 ml/min. CONCLUSION: The introduction of ion-mobility separation into a bioanalytical LC-MS/MS method can remove unexpected isobaric interferences without the need to redevelop the chromatography.

RESUMEN

BACKGROUND: Depression in end-stage renal disease patients is detrimental to quality of life, and is also associated with adverse clinical outcomes. The aim of this study was to examine whether depression symptoms in 'incident dialysis' patients predicted survival. METHODS: One hundred and sixty incident haemodialysis and peritoneal dialysis patients completed a self-report depression questionnaire (Beck Depression Inventory-II, BDI) at a point soon after dialysis initiation. Over the study period (May 2007-December 2009), patients were followed up with all-cause mortality recorded as the end point. RESULTS: The median follow-up time for the cohort was 511 days (min 47 days and max 1027 days). There were 27 deaths (16.9%). Depression symptoms were evaluated both as a continuous variable and using a defined cut-off for depressed patients (BDI ≥ 16). In a Cox proportional hazards model, adjusted for several covariates including albumin and extra renal comorbidity, depression score was an independent predictor of mortality (HR = 1.07, 95% CI 1.02-1.11, P = 0.002). In an additional adjusted model, a BDI score ≥ 16 was associated with a 2.7 times increase in the hazard for death (HR = 2.7, 95% CI 1.06-6.8, P = 0.037). CONCLUSIONS: The severity of depression symptoms following the start of dialysis treatment is an independent predictor of survival. Further studies will be required to determine whether the treatment of depression would alter health-related outcomes, including survival.

RESUMEN

We report the case of a 34-year-old previously fit and healthy male who presented to the accident & emergency department with non-specific abdominal pain. The patient proceeded to undergo laparotomy at which a large mass was found adjacent to the stomach. The impression at surgery was of a lymphoma or gastric carcinoma though CT had reported the likelihood of a fish bone or foreign body causing duodenal perforation. Histology later confirmed the presence of a fish bone surrounded by reactive tissue.

RESUMEN

PURPOSE: To examine if N-acetylcysteine (NAC) reduces the incidence of contrast nephropathy during endovascular abdominal aortic aneurysm repair (EVAR) as evidenced by changes in markers of renal function. METHODS: Twenty consecutive men (mean age 72 years, range 65-79) undergoing EVAR were randomized to receive standard intravenous fluid hydration or standard fluid hydration and NAC (600 mg BID orally, 4 doses). Venous blood and urine were collected prior to the procedure and for 5 postoperative days and analyzed blindly for serum creatinine, urinary retinol-binding protein (RBP), and albumin/creatinine ratio (ACR). RESULTS: There were no significant differences in baseline demographics between the groups. No patient developed acute renal failure. In both groups, urinary RBP rose significantly from baseline (median 15 microg/mmol to peak 699 microg/mmol in controls versus 17 to 648 microg/mmol in the treatment group, p<0.003). There were similar significant rises in ACR (p<0.02). There was, however, no significant difference in the postoperative RBP or ACR between the groups at any time point. CONCLUSION: EVAR causes significant acute renal injury in most patients. This was not attenuated by N-acetylcysteine. The causes of renal injury are probably multifactorial, the long-term clinical significance of which is unclear.

RESUMEN

Maintenance immunosuppression with calcineurin inhibitors (CNIs) following renal transplantation is associated with nephrotoxicity and accelerated graft loss. We aimed to assess whether conversion to sirolimus-based immunosuppression would affect the progression of renal impairment. In this single center, randomized controlled trial, 40 renal transplant recipients between 6 months and 8 years post-transplant were randomly assigned to remain on their CNI (cyclosporin or tacrolimus) or to switch to sirolimus. The primary outcome measure was change in glomerular filtration rate (GFR) measurement at 12 months. Analysis was by intention-to-treat. Of the 40 patients randomized, 2 patients never took the study drugs and were excluded, leaving 19 patients per group. There was a significant change in GFR at 12 months following conversion to sirolimus (12.9 mL/min, 95% CI 6.1-19.7; p < 0.001). Following conversion, the principal adverse events were the development of rashes (68%), particularly acne, and mouth ulcers (32%). No patient in either group experienced an acute rejection episode. In renal transplant recipients, a change in maintenance therapy from CNIs to sirolimus is associated with significant improvement in GFR at 12 months.
