RESUMO

People with learning disabilities in England and Scotland have experienced an increased risk of illness and death during the COVID-19 pandemic. Drawing on data of a longitudinal qualitative study with 71 disabled people and 31 disability organisations, this article examines the experiences of 24 people with learning disabilities in England and Scotland during the pandemic, reflecting on what rendered them vulnerable and placed them at risk. Qualitative interviews were conducted with participants and key informants at two timepoints; June-August 2020 and February-April 2021. Findings emerged across four key themes: failure to plan for the needs of people with learning disabilities; the suspension and removal of social care; the impact of the pandemic on people's everyday routines; and lack of vaccine prioritisation. The inequalities experienced by people with learning disabilities in this study are not particular to the pandemic. We explore the findings in the context of theoretical frameworks of vulnerability, including Fineman's conceptualisation of a 'vulnerability paradigm'. We conclude that the structured marginalisation of people with disabilities, entrenched by government action and inaction, have created and exacerbated their vulnerability. Structures, policies and action must change.

RESUMO

UNLABELLED: Cholestatic liver dysfunction (CLD) and biliary sludge often occur during critical illness and are allegedly aggravated by parenteral nutrition (PN). Delaying initiation of PN beyond day 7 in the intensive care unit (ICU) (late PN) accelerated recovery as compared with early initiation of PN (early PN). However, the impact of nutritional strategy on biliary sludge and CLD has not been fully characterized. This was a preplanned subanalysis of a large randomized controlled trial of early PN versus late PN (n = 4,640). In all patients plasma bilirubin (daily) and liver enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST], gamma-glutamyl transpeptidase [GGT], alkaline phosphatase [ALP], twice weekly; n = 3,216) were quantified. In a random predefined subset of patients, plasma bile acids (BAs) were also quantified at baseline and on days 3, 5, and last ICU-day (n = 280). Biliary sludge was ultrasonographically evaluated on ICU-day 5 (n = 776). From day 1 after randomization until the end of the 7-day intervention window, bilirubin was higher in the late PN than in the early PN group (P < 0.001). In the late PN group, as soon as PN was started on day 8 bilirubin fell and the two groups became comparable. Maximum levels of GGT, ALP, and ALT were lower in the late PN group (P < 0.01). Glycine/taurine-conjugated primary BAs increased over time in ICU (P < 0.01), similarly for the two groups. Fewer patients in the late PN than in the early PN group developed biliary sludge on day 5 (37% versus 45%; P = 0.04). CONCLUSION: Tolerating substantial caloric deficit by withholding PN until day 8 of critical illness increased plasma bilirubin but reduced the occurrence of biliary sludge and lowered GGT, ALP, and ALT. These results suggest that hyperbilirubinemia during critical illness does not necessarily reflect cholestasis and instead may be an adaptive response that is suppressed by early PN.

RESUMO

INTRODUCTION: Targeted temperature management improves outcome after cardiopulmonary resuscitation. Reduction of resting energy expenditure might be one mode of action. The aim of this study was to correlate resting energy expenditure and substrate oxidation rates with targeted temperature management at 33°C and outcome in patients after cardiac arrest. METHODS: This prospective, observational cohort study was performed at the department of emergency medicine and a medical intensive care unit of a university hospital. Patients after successful cardiopulmonary resuscitation undergoing targeted temperature management at 33°C for 24 hours with subsequent rewarming to 36°C and standardized sedation, analgesic and paralytic medication were included. Indirect calorimetry was performed five times within 48 h after cardiac arrest. Measurements were correlated to outcome with repeated measures ANOVA, linear and logistic regression analysis. RESULTS: In 25 patients resting energy expenditure decreased 20 (18 to 27) % at 33°C compared to 36°C without differences between outcome groups (favourable vs. unfavourable: 25 (21 to 26) vs. 21 (16 to 26); P = 0.5). In contrast to protein oxidation rate (favourable vs. unfavourable: 35 (11 to 68) g/day vs. 39 (7 to 75) g/day, P = 0.8) patients with favourable outcome had a significantly higher fat oxidation rate (139 (104 to 171) g/day vs. 117 (70 to 139) g/day, P <0.05) and a significantly lower glucose oxidation rate (30 (-34 to 88) g/day vs. 77 (19 to 138) g/day; P < 0.05) as compared to patients with unfavourable neurological outcome. CONCLUSIONS: Targeted temperature management at 33°C after cardiac arrest reduces resting energy expenditure by 20% compared to 36°C. Glucose and fat oxidation rates differ significantly between patients with favourable and unfavourable neurological outcome. TRIAL REGISTRATION: Clinicaltrials.gov NCT00500825.

RESUMO

INTRODUCTION: Hyperchloremic acidosis is frequent in critically ill patients. Renal tubular acidosis (RTA) may contribute to acidemia in the state of hyperchloremic acidosis, but the prevalence of RTA has never been studied in critically ill patients. Therefore, we aimed to investigate the prevalence, type, and possible risk factors of RTA in critically ill patients using a physical-chemical approach. METHODS: This prospective, observational trial was conducted in a medical ICU of a university hospital. One hundred consecutive critically ill patients at the age ≥18, expected to stay in the ICU for ≥24 h, with the clinical necessity for a urinary catheter and the absence of anuria were included. Base excess (BE) subset calculation based on a physical-chemical approach on the first 7 days after ICU admission was used to compare the effects of free water, chloride, albumin, and unmeasured anions on the standard base excess. Calculation of the urine osmolal gap (UOG)--as an approximate measure of the unmeasured urine cation NH4(+)--served as determinate between renal and extrarenal bicarbonate loss in the state of hyperchloremic acidosis. RESULTS: During the first week of ICU stay 43 of the patients presented with hyperchloremic acidosis on one or more days represented as pronounced negative BEChloride. In 31 patients hyperchloremic acidosis was associated with RTA characterized by a UOG ≤150 mosmol/kg in combination with preserved renal function. However, in 26 of the 31 patients with RTA metabolic acidosis was neutralized by other acid-base disturbances leading to a normal arterial pH. CONCLUSIONS: RTA is highly prevalent in critically ill patients with hyperchloremic acidosis, whereas it is often neutralized by the simultaneous occurrence of other acid-base disturbances.

RESUMO

The 'renal threshold for glucose' has never been evaluated in critically ill patients. Therefore, we aimed to investigate the renal glucose threshold in this patient group using high-sensitivity urine glucose assays. In this retrospective analysis of prospectively collected data, we analysed 100 consecutive critically ill patients from a medical intensive care unit (ICU). Arterial blood glucose and spot urine glucose were simultaneously quantified daily during the first week after ICU admission. Three hundred seventy-three pairs of blood/urine glucose were plotted in five pre-defined categories of blood glucose (<80, 80-109, 110-139, 140-179 and ≥180 mg/dL). Urine glucose values of the five categories were compared using the Kruskal-Wallis test to assess the relation with blood glucose. Urine glucose was detected in virtually all of the urine samples. Urine glucose showed a positive nonlinear correlation with blood glucose and was significantly elevated at blood glucose levels of 140-179 and ≥180 mg/dL compared with lower blood glucose ranges. Basal glucosuria is ubiquitous in critically ill patients. A 'soft' renal threshold for glucose is present at blood glucose levels in the range of 140-179 mg/dL.

RESUMO

INTRODUCTION: Critical illness polyneuropathy and/or myopathy (CIPNM) is a severe complication of critical illness. Retrospective data suggest that early application of IgM-enriched intravenous immunoglobulin (IVIG) may prevent or mitigate CIPNM. Therefore, the primary objective was to assess the effect of early IgM-enriched IVIG versus placebo to mitigate CIPNM in a prospective setting. METHODS: In this prospective, randomized, double-blinded and placebo-controlled trial, 38 critically ill patients with multiple organ failure (MOF), systemic inflammatory response syndrome (SIRS)/sepsis, and early clinical signs of CIPNM were included. Patients were randomly assigned to be treated either with IgM-enriched IVIG or placebo over a period of three days. CIPNM was measured by the CIPNM severity sum score based on electrophysiological stimulation of the median, ulnar, and tibial nerves on days 0, 4, 7, 14 and on the histological evaluation of muscle biopsies on days 0 and 14 and ranged from 0 (no CIPNM) to 8 (very severe CIPNM). RESULTS: A total of 38 critically ill patients were included and randomized to receive either IgM-enriched IVIG (n = 19) or placebo (n = 19). Baseline characteristics were similar between the two groups. CIPNM could not be improved by IVIG treatment, represented by similar CIPNM severity sum scores on day 14 (IVIG vs. placebo: 4.8 ± 2.0 vs. 4.5 ± 1.8; P = 0.70). CIPNM severity sum score significantly increased from baseline to day 14 (3.5 ± 1.6 vs. 4.6 ± 1.9; P = 0.002). After an interim analysis the study was terminated early due to futility in reaching the primary endpoint. CONCLUSIONS: Early treatment with IVIG did not mitigate CIPNM in critically ill patients with MOF and SIRS/sepsis. TRIAL REGISTRATION: Clinicaltrials.gov: NCT01867645.

RESUMO

BACKGROUND: Adequate anticoagulation is essential to achieve efficient and cost-effective continuous renal replacement therapy (CRRT). However, in critically ill patients with advanced liver cirrhosis, this goal is challenging because of the concomitant bleeding disorder. Therefore, the evaluation of alternative anticoagulants is necessary. METHODS: In this retrospective study, we analyzed data of 37 CRRTs in 16 critically ill patients with advanced liver cirrhosis and acute kidney injury admitted to a medical intensive care unit between 2006 and 2008 and included patients undergoing CRRT with either single doses of antithrombin (AT) or continuous low-dose heparin as a sole anticoagulant. The primary outcome measure was lifetime of single CRRT filters. RESULTS: Data were available for 13 CRRT filters for patients anticoagulated with single doses of AT (n = 6), and 24 CRRT filters for patients anticoagulated continuously with low-dose heparin (n = 10). Means of single-filter lifetimes were significantly higher in the AT group compared with the heparin group (45 ± 29 hours [95% confidence interval 27-62 hours] vs 26 ± 23 hours [95% confidence interval 16-36 hours]; P = 0.03), whereas mean filter lifetimes of individual patients were comparable (median [25th-75th percentile] 30 hours [21-59 hours] vs 28 hours [17-70 hours]; P = 0.79). CONCLUSIONS: Our data suggest that anticoagulation with single doses of AT may be an alternative to continuously administered low-dose heparin in critically ill patients with advanced liver cirrhosis during CRRT. However, additional controlled trials are necessary to confirm our findings.

RESUMO

INTRODUCTION: Glycemic variability as a marker of endogenous and exogenous factors, and glucose complexity as a marker of endogenous glucose regulation are independent predictors of mortality in critically ill patients. We evaluated the impact of real time continuous glucose monitoring (CGM) on glycemic variability in critically ill patients on intensive insulin therapy (IIT), and investigated glucose complexity--calculated using detrended fluctuation analysis (DFA)--in ICU survivors and non-survivors. METHODS: Retrospective analysis were conducted of two prospective, randomized, controlled trials in which 174 critically ill patients either received IIT according to a real-time CGM system (n = 63) or according to an algorithm (n = 111) guided by selective arterial blood glucose measurements with simultaneously blinded CGM for 72 hours. Standard deviation, glucose lability index and mean daily delta glucose as markers of glycemic variability, as well as glucose complexity and mean glucose were calculated. RESULTS: Glycemic variability measures were comparable between the real time CGM group (n = 63) and the controls (n = 111). Glucose complexity was significantly lower (higher DFA) in ICU non-survivors (n = 36) compared to survivors (n = 138) (DFA: 1.61 (1.46 to 1.68) versus 1.52 (1.44 to 1.58); P = 0.003). Diabetes mellitus was significantly associated with a loss of complexity (diabetic (n = 33) versus non-diabetic patients (n = 141) (DFA: 1.58 (1.48 to 1.65) versus 1.53 (1.44 to 1.59); P = 0.01). CONCLUSIONS: IIT guided by real time CGM did not result in significantly reduced glycemic variability. Loss of glucose complexity was significantly associated with mortality and with the presence of diabetes mellitus.

RESUMO

This paper reports on in-depth qualitative interviews conducted with 69 disabled people in England and Scotland, and with 28 key informants from infrastructure organisations in the voluntary and statutory sectors, about the impact of COVID-19, and measures taken to control it. Participants were recruited through voluntary organisations. As with everyone, the Pandemic has had a huge impact: we discuss the dislocations it has caused in everyday life; the failures of social care; the use of new technologies; and participants' view on leadership and communication. We conclude with suggestions for urgent short term and medium term responses, so that the United Kingdom and other countries can respond better to this and other pandemics, and build a more inclusive world.

RESUMO

BACKGROUND: Continuous glucose monitoring has been proposed to optimize glucose control in critically ill patients. To achieve strict glucose regulation, accurate and reliable continuous glucose-monitoring systems are essential. OBJECTIVE: Evaluation of a subcutaneous continuous glucose-monitoring system for use in critically ill patients. DESIGN: Pooled-data analysis of two prospective, randomized, controlled trials. SETTING: An eight-bed medical intensive care unit of a university hospital. PATIENTS: A total of 174 critically ill patients on intensive insulin therapy. INTERVENTIONS: Subcutaneous continuous glucose monitoring. MEASUREMENTS: Two thousand forty-five continuous glucose-monitoring system sensor glucose values were compared with arterial reference blood glucose levels, determined by a blood gas analyzer. Continuous glucose monitoring data were recorded continuously for up to 72 hrs by using a subcutaneous continuous glucose-monitoring sensor. The correlation of both methods and differences between continuous glucose-monitoring systems and reference values were calculated, as well as the conformity of continuous glucose-monitoring values with the International Organization for Standardization criteria (<0.83 mmol/L [15 mg/dL] difference for glucose values ≤ 4.12 mmol/L [≤ 75 mg/dL] and <20% difference for glucose values >4.12 mmol/L [>75 mg/dL]). RESULTS: The Pearson correlation coefficient was 0.92, showing strong correlation between the two methods. The intraclass correlation coefficient was 0.92, indicating that 92% of the variability is due to subjects and measurement occasions. Mean difference between continuous glucose-monitoring system and reference values was -0.10 mmol/L (confidence interval: -0.13 to -0.07) (-2 mg/dL [confidence interval: -2 to -1]) (continuous glucose-monitoring system minus reference) and absolute difference 0.44 mmol/L (confidence interval: 0.41-0.47) (8 mg/dL [confidence interval: 7-8]). According to the insulin titration error grid analysis, 99.1% of continuous glucose-monitoring system values were in the acceptable treatment zone. No continuous glucose-monitoring system measurements were found in the life-threatening zone, and 92.9% of the continuous glucose-monitoring system glucose values met the International Organization for Standardization criteria. CONCLUSION: The subcutaneous continuous glucose-monitoring system is reliable for use in critically ill patients and showed glucose values with a strong correlation to arterial reference blood glucose levels, determined by a blood gas analyzer.

RESUMO

OBJECTIVE: Head-to-head comparison of the success rate of jejunal placement of a new electromagnetically visualized jejunal tube with that of the endoscopic technique in critically ill patients. DESIGN: : Prospective, randomized clinical trial. SETTING: Two intensive care units at a university hospital. PATIENTS: : A total of 66 critically ill patients not tolerating intragastric nutrition. INTERVENTIONS: Patients were randomly assigned (2:1 ratio) to receive an electromagnetically visualized jejunal feeding tube or an endoscopically placed jejunal tube. The success rate of correct jejunal placement after 24 hrs was the main outcome parameter. MEASUREMENTS AND MAIN RESULTS: The correct jejunal tube position was reached in 21 of 22 patients using the endoscopic technique and in 40 of 44 patients using the electromagnetically visualized jejunal tube (95% vs. 91%; relative risk 0.9524, confidence interval 0.804-1.127, p = .571). In the remaining four patients, successful endoscopic jejunal tube placement was performed subsequently. The implantation times, times in the right position, and occurrences of nose bleeding were not different between the two groups. The electromagnetically visualized technique resulted in the correct jejunal position more often at the first attempt. Factors associated with successful placement at the first attempt of the electromagnetically visualized jejunal tube seem to be a higher body mass index and absence of emesis. This trial is registered at ClinicalTrials.gov, number NCT00500851. CONCLUSIONS: In a head-to-head comparison correct jejunal tube placement using the new electromagnetically visualized method was as fast, safe, and successful as the endoscopic method in a comparative intensive care unit patient population.

RESUMO

Evaluation is essential to understand whether and how policies and other interventions work, why they sometimes fail, and whether they represent a good use of resources. Evaluability assessment (EA) is a means of collaboratively planning and designing evaluations, seeking to ensure they generate relevant and robust evidence that supports decision-making and contributes to the wider evidence base. This article reports on the context, the process undertaken and evidence from participants in an EA facilitated with public service workers involved in implementing a complex, area-based community improvement initiative. This is a novel context in which to conduct an EA. We show how the process allows practitioners at all levels to identify activities for evaluation and co-produce the theory of change developed through the EA. This enables evaluation recommendations to be developed that are relevant to the implementation of the programme, and which take account of available data and resources for evaluation.

RESUMO

BACKGROUND: Acid-base disturbances are frequently observed in critically ill patients at the intensive care unit. To our knowledge, the acid-base profile of patients with acute-on-chronic liver failure (ACLF) has not been evaluated and compared to critically ill patients without acute or chronic liver disease. RESULTS: One hundred and seventy-eight critically ill patients with liver cirrhosis were compared to 178 matched controls in this post hoc analysis of prospectively collected data. Patients with and without liver cirrhosis showed hyperchloremic acidosis and coexisting hypoalbuminemic alkalosis. Cirrhotic patients, especially those with ACLF, showed a marked net metabolic acidosis owing to increased lactate and unmeasured anions. This metabolic acidosis was partly antagonized by associated respiratory alkalosis, yet with progression to ACLF resulted in acidemia, which was present in 62% of patients with ACLF grade III compared to 19% in cirrhosis patients without ACLF. Acidemia and metabolic acidosis were associated with 28-day mortality in cirrhosis. Patients with pH values < 7.1 showed a 100% mortality rate. Acidosis attributable to lactate and unmeasured anions was independently associated with mortality in liver cirrhosis. CONCLUSIONS: Cirrhosis and especially ACLF are associated with metabolic acidosis and acidemia owing to lactate and unmeasured anions. Acidosis and acidemia, respectively, are associated with increased 28-day mortality in liver cirrhosis. Lactate and unmeasured anions are main contributors to metabolic imbalance in cirrhosis and ACLF.

RESUMO

Macro level data indicate that people experiencing mental distress experience poor health, social and economic outcomes. The sociology of mental health has a series of dominant competing explanations of the mechanisms at personal, social and structural levels that generate these poor outcomes. This article explains the limitations of these approaches and takes up the challenge of Hopper (2007) who in this journal proposed the capabilities approach as a means of normatively reconceptualising the experiences of people with mental distress, with a renewed focus on agency, equality and genuine opportunity. Using an innovative methodology to operationalise the capabilities approach, findings from an in-depth qualitative study exploring the lived experiences of twenty-two people with recent inpatient experience of psychiatric units in Scotland are presented. The paper demonstrates that the capabilities approach can be applied to reconceptualise how unjust social outcomes happen for this social group. It distinguishes how the results of using a capabilities approach to analysis are distinct from established dominant analytical frameworks through four added features: a focus on actual lived outcomes; the role of capabilities as well as functionings; being normative; and incorporating agency. The capabilities approach is found to be an operationalisable framework; the findings have implications for professionals and systems in the specific context of mental health; and the capabilities approach offers a fertile basis for normative studies in wider aspects of health and wellbeing.

RESUMO

PURPOSE: An association between multiple sclerosis during childhood and uveitis is exceptionally rare. This is a report of a female patient who presented at the age of 8 years with bilateral intermediate uveitis and whose final diagnosis of multiple sclerosis was made at age 21 years. DESIGN: Case report. METHOD: Retrospective chart review of a 13-year follow-up history. RESULTS: Over 10 years our patient was treated systemically and underwent bilateral vitrectomy to reduce permanent side effects. Owing to good visual function and low inflammatory signs, systemic therapy was stopped. Multiple sclerosis was diagnosed at the age of 21, after a 13-year history of uveitis and after 3 years without medication. CONCLUSIONS: In the constellation of uveitis in childhood and later diagnosis of multiple sclerosis, the outlined therapy provided good functional results. Moreover, it may have delayed the manifestation of the underlying disease for 13 years.

RESUMO

To investigate the effect of membrane differential filtration (MDF) on plasma colloid osmotic pressure (COP) and visual functions in age-related geographic macular degeneration (AMD). Ten consecutive patients with non-exudative AMD underwent one MDF cycle. Primary endpoint was COP. Secondary endpoints were visual acuity and the mean defect of visual field. The COP was markedly reduced after one MDF cycle by 23.9% (P = 0.001). Compared with the baseline examination, visual acuity and the mean defect of visual field improved significantly after MDF. A significant positive correlation was found between the improvement in visual field and the decrease in COP (Pearson's coefficient = 0.65; P = 0.04). Membrane differential filtration lowers plasma colloid osmotic pressure in patients with non-exudative AMD. Based on the observation that visual field and COP are correlated, one may hope for a means to improve decreased central retinal function in eyes with geographic AMD by modulation of COP plasma level.

RESUMO

Mal d 2 is a minor allergen from apple which shows a high conformational stability due to its eight conserved disulfide bridges. Chemical reduction of disulfide bridges and linearization of Mal d 2 lead to enhanced IgE reactivity in vitro and indicate a higher potential for allergenicity. Since food preservatives such as sulfur and vitamin C are reducing and denaturing agents, their influence on Mal d 2 allergenicity was verified by simulated food processing conditions. The immunoreactivity of purified Mal d 2 was investigated after different treatments in vitro and in vivo using IgG/IgE Western blotting, mediator-releasing cell assay, and skin prick and oral smear tests. The conformational changes of Mal d 2 upon addition of 1% and 5% vitamin C were also monitored by attenuated total reflectance Fourier transform infrared spectroscopy. The results show no positive skin and oral smear test reactivity to native, heated, or vitamin C-treated purified Mal d 2. Furthermore, the results confirm that sulfur in combination with heat treatment can influence the structural integrity and thus the allergenicity of Mal d 2, while vitamin C is too weak as a reducing agent to change allergenicity.

RESUMO

SCOPE: Patients with persistent egg allergy have more immunoglobulin E (IgE) against sequential than conformational epitopes of ovomucoid (OVO). Here, we aimed to identify compounds capable to render sequential epitopes in egg. METHODS AND RESULTS: Glutathione was used for in vitro reduction of OVO and circular dichroism analyses were performed. Glutathione reduced OVO in a concentration-dependent manner. Egg white was analyzed for reduced proteins with a thiol probe and by MALDI-TOF/TOF. In unprocessed total egg white, several reduced proteins were detected by the thiol probe, among them reduced ovalbumin could be confirmed with MS analyses. Egg-allergics or sensitized controls were tested serologically (n = 19) for IgE against native and reduced OVO and in skin prick tests (n = 9). More patients had IgE against reduced than native OVO in Western blots. In skin prick test, five out of seven persistent egg-allergics and none of the controls reacted with reduced OVO. CONCLUSION: Reduced egg proteins are present in natural egg white. Glutathione, which is present in egg and furthermore is used as texture-improving additive in processed food, is capable of reducing OVO. Patients with persistent egg allergy reacted rather to reduce the native OVO. Hence, our data indicate that reduction is a novel natural and processing-associated principle, which contributes to the allergenicity of food.

RESUMO

Adjuvants are compounds that can increase and/or modulate the intrinsic immunogenicity of an antigen and elicit strong and long lasting immune responses. During the last 80 years many adjuvants have been used in experimental settings, but due to various shortcomings of most of them only aluminum compounds made it into regular clinical usage. However, during the last years promising candidates have arisen that may finally adjunct or displace aluminum substances as main adjuvant. This review summarizes information on adjuvants currently used in clinical as well as in experimental settings.

RESUMO

OBJECTIVE: To determine the prevalence of the spondyloarthritides in patients with uveitis and to establish criteria for certain subtypes of this group of diseases. METHODS: In a university-based prospective study, we examined 433 patients with different types of uveitis for signs of spondyloarthritides as defined by the classification criteria of the European Spondylarthropathy Study Group (ESSG). RESULTS: Forty-four of the 433 uveitis patients (36 with acute anterior uveitis and 8 with other types of uveitis) had spondyloarthritis according to the ESSG classification criteria. Nineteen of these 44 patients had ankylosing spondylitis (AS), 11 had undifferentiated spondyloarthritis, 9 reactive arthritis, and 5 psoriatic arthritis. CONCLUSION: Uveitis is associated not only with AS and reactive arthritis, but also with undifferentiated spondyloarthritis and psoriatic arthritis. The ESSG criteria are helpful in identifying these spondyloarthritides in uveitis patients.
