RESUMO

BACKGROUND AND PURPOSE: The prevalence and duration of non-motor symptoms (NMS) in prodromal Parkinson's disease (PD) has not been extensively studied. The aim of this study was to determine the prevalence and duration of prodromal NMS (pNMS) in a cohort of patients with recently diagnosed PD. METHODS: We evaluated the prevalence and duration of pNMS in patients with early PD (n = 154). NMS were screened for using the Non-Motor Symptom Questionnaire (NMSQuest). We subtracted the duration of the presence of each individual NMS reported from the duration of the earliest motor symptom. NMS whose duration preceded the duration of motor symptoms were considered a pNMS. Individual pNMS were then grouped into relevant pNMS clusters based on the NMSQuest domains. Motor subtypes were defined as tremor dominant, postural instability gait difficulty (PIGD) and indeterminate type according to the Movement Disorder Society Unified Parkinson's Disease Rating Scale revision. RESULTS: Prodromal NMS were experienced by 90.3% of patients with PD and the median number experienced was 4 (interquartile range, 2-7). A gender difference existed in the pNMS experienced, with males reporting more sexual dysfunction, forgetfulness and dream re-enactment, whereas females reported more unexplained weight change and anxiety. There was a significant association between any prodromal gastrointestinal symptoms [odds ratio (OR), 2.30; 95% confidence interval (CI), 1.08-4.89, P = 0.03] and urinary symptoms (OR, 2.54; 95% CI, 1.19-5.35, P = 0.016) and the PIGD phenotype. Further analysis revealed that total pNMS were not significantly associated with the PIGD phenotype (OR, 1.10; 95% CI, 0.99-1.21, P = 0.068). CONCLUSIONS: Prodromal NMS are common and a gender difference in pNMS experienced in prodromal PD may exist. The PIGD phenotype had a higher prevalence of prodromal gastrointestinal and urinary tract symptoms.

RESUMO

OBJECTIVE: To assess reductions of cerebral glucose metabolism in Parkinson's disease (PD) with 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET), and their associations with cognitive decline. METHODS: FDG-PET was performed on a cohort of 79 patients with newly diagnosed PD (mean disease duration 8 months) and 20 unrelated controls. PD participants were scanned while on their usual dopaminergic medication. Cognitive testing was performed at baseline, and after 18 months using the Cognitive Drug Research (CDR) and Cambridge Neuropsychological Test Automated Battery (CANTAB) computerised batteries, the Mini-Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). We used statistical parametric mapping (SPM V.12) software to compare groups and investigate voxelwise correlations between FDG metabolism and cognitive score at baseline. Linear regression was used to evaluate how levels of cortical FDG metabolism were predictive of subsequent cognitive decline rated with the MMSE and MoCA. RESULTS: PD participants showed reduced glucose metabolism in the occipital and inferior parietal lobes relative to controls. Low performance on memory-based tasks was associated with reduced FDG metabolism in posterior parietal and temporal regions, while attentional performance was associated with more frontal deficits. Baseline parietal to cerebellum FDG metabolism ratios predicted MMSE (ß=0.38, p=0.001) and MoCA (ß=0.3, p=0.002) at 18 months controlling for baseline score. CONCLUSIONS: Reductions in cortical FDG metabolism were present in newly diagnosed PD, and correlated with performance on neuropsychological tests. A reduced baseline parietal metabolism is associated with risk of cognitive decline and may represent a potential biomarker for this state and the development of PD dementia.

RESUMO

BACKGROUND: The quality of life (QoL) of informal caregivers of people with Parkinson's disease (PD) (PwP) can be affected by the caring role. Because of cognitive symptoms and diminished activities of daily living, in addition to the management of motor symptoms, carers of PwP and cognitive impairment may experience increased levels of burden and poorer QoL compared with carers of PwP without cognitive impairment. This study aimed to investigate the impact of cognitive impairment in PD upon QoL of carers. METHODS: Approximately 36 months after diagnosis, 66 dyadic couples of PwP and carers completed assessments. PwP completed a schedule of neuropsychological assessments and QoL measures; carers of PwP completed demographic questionnaires and assessments of QoL. Factor scores of attention, memory/executive function and global cognition, as derived by principal component analysis, were used to evaluate cognitive domains. RESULTS: Hierarchical regression analysis found lower Montreal Cognitive Assessment was a significant independent predictor of poorer carer QoL, in addition to number of hours spent caregiving, carer depression and PD motor severity. Attentional deficits accounted for the largest proportion of variance of carer QoL. Carers of PwP and dementia (n = 9) had significantly poorer QoL scores compared with PwP and mild cognitive impairment (n = 18) or normal cognition (n = 39) carers (p < 0.01). CONCLUSIONS: Attentional deficits were the strongest predictor of carer QoL compared with other cognitive predictors. Carers for those with PD dementia reported the poorest QoL. Interventions such as respite or cognitive behavioural therapy to improve mood and self-efficacy in carers may improve carer QoL. © 2016 The Authors.

RESUMO

OBJECTIVES: What explains increases in BMI (and obesity) over time and across countries? Although many microeconomic forces are likely explanations, increasingly scholars are arguing that macroeconomic forces such as market liberalism and globalization are root causes of the obesity epidemic. The purpose of this paper is to examine the impact of economic freedom on obesity conditional on the level of income and other factors. STUDY DESIGN: We use an unbalanced pooled cross section of up to 135 countries for 1995 and 2000-2009. METHODS: Our statistical model specifications include pooled OLS and fixed effects. RESULTS: First, we find that controlling for fixed effects siphons off much of the relationship previously documented between economic freedom and BMI. Second, economic freedom is associated with slightly higher BMIs but only for men in developing nations. Lastly, we show that economic freedom increases life expectancy for both men and women in developing countries. CONCLUSION: Therefore, policies aimed at reducing obesity that limit economic liberalism may come at the expense of life expectancy in the developing world.

RESUMO

INTRODUCTION: Lung volume reduction surgery (LVRS) and endobronchial valve (EBV) placement can produce substantial benefits in appropriately selected people with emphysema. The UK Lung Volume Reduction (UKLVR) registry is a national multicentre observational study set up to support quality standards and assess outcomes from LVR procedures at specialist centres across the UK. METHODS: Data were analysed for all patients undergoing an LVR procedure (LVRS/EBV) who were recruited into the study at participating centres between January 2017 and June 2022, including; disease severity and risk assessment, compliance with guidelines for selection, procedural complications and survival to February 2023. RESULTS: Data on 541 patients from 14 participating centres were analysed. Baseline disease severity was similar in patients who had surgery n=244 (44.9%), or EBV placement n=219 (40.9%), for example, forced expiratory volume in 1 s (FEV1) 32.1 (12.1)% vs 31.2 (11.6)%. 89% of cases had discussion at a multidisciplinary meeting recorded. Median (IQR) length of stay postprocedure for LVRS and EBVs was 12 (13) vs 4 (4) days(p=0.01). Increasing age, male gender and lower FEV1%predicted were associated with mortality risk, but survival did not differ between the two procedures, with 50 (10.8%) deaths during follow-up in the LVRS group vs 45 (9.7%) following EBVs (adjusted HR 1.10 (95% CI 0.72 to 1.67) p=0.661) CONCLUSION: Based on data entered in the UKLVR registry, LVRS and EBV procedures for emphysema are being performed in people with similar disease severity and long-term survival is similar in both groups.

RESUMO

INTRODUCTION: Pain is a common non-motor symptom in Parkinson's disease (PD), affecting up to 85% of patients. The frequency and stability of pain over time has not been extensively studied. There is a paucity of high-quality studies investigating pain management in PD. To develop interventions, an understanding of how pain changes over the disease course is required. METHODS: One hundred and fifty-four participants with early PD and 99 age-and-sex-matched controls were recruited as part of a longitudinal study (Incidence of Cognitive Impairment in Cohorts with Longitudinal Evaluation in PD, ICICLE-PD). Pain data were collected at 18-month intervals over 72 months in both groups using the Nonmotor Symptom Questionnaire (NMSQ), consisting of a binary yes/no response. Two questions from the Parkinson's Disease Questionnaire (PDQ-39) were analysed for the PD group only. RESULTS: Unexplained pain was common in the PD group and occurred more frequently than in age-matched controls. 'Aches and pains' occurred more frequently than 'cramps and muscle spasms' at each time point (p < 0.001) except 54 months. CONCLUSIONS: This study shows that pain is prevalent even in the early stages of PD, yet the frequency and type of pain fluctuates as symptoms progress. People with PD should be asked about their pain at clinical consultations and given support with describing pain given the different ways this can present.

RESUMO

Constipation is a common but not a universal feature in early PD, suggesting that gut involvement is heterogeneous and may be part of a distinct PD subtype with prognostic implications. We analysed data from the Parkinson's Incidence Cohorts Collaboration, composed of incident community-based cohorts of PD patients assessed longitudinally over 8 years. Constipation was assessed with the MDS-UPDRS constipation item or a comparable categorical scale. Primary PD outcomes of interest were dementia, postural instability and death. PD patients were stratified according to constipation severity at diagnosis: none (n = 313, 67.3%), minor (n = 97, 20.9%) and major (n = 55, 11.8%). Clinical progression to all three outcomes was more rapid in those with more severe constipation at baseline (Kaplan-Meier survival analysis). Cox regression analysis, adjusting for relevant confounders, confirmed a significant relationship between constipation severity and progression to dementia, but not postural instability or death. Early constipation may predict an accelerated progression of neurodegenerative pathology.

RESUMO

BACKGROUND: Cross-sectional studies have identified that the prevalence of neuropsychiatric symptoms (NPS) in Parkinson's disease (PD) ranges from 70-89%. However, there are few longitudinal studies determining the impact of NPS on quality of life (QoL) in PD patients and their caregivers. We seek to determine the progression of NPS in early PD. METHODS: Newly diagnosed idiopathic PD cases (n = 212) and age-matched controls (n = 99) were recruited into a longitudinal study. NPS were assessed using the Neuropsychiatric Inventory with Caregiver Distress scale (NPI-D). Further neuropsychological and clinical assessments were completed by participants, with reassessment at 18 and 36 months. Linear mixed-effects modelling determined factors associated with NPI-D and QoL over 36 months. RESULTS: Depression, anxiety, apathy and hallucinations were more frequent in PD than controls at all time points (p < 0.05). Higher motor severity at baseline was associated with worsening NPI-D scores over time (ß = 0.1, p < 0.05), but not cognition. A higher NPI total score was associated with poorer QoL at any time point (ß = 0.3, p < 0.001), but not changed in QoL scores. CONCLUSION: NPS are significantly associated with poorer QoL, even in early PD. Screening for NPS from diagnosis may allow efficient delivery of better support and treatment to patients and their families.

RESUMO

Specific homologous radioimmunoassays for the two major porcine neurophysins have been developed and utilized to measure plasma neurophysins during events known to release vasopressin (dehydration and hemorrhage) and oxytocin (parturition and suckling). During hemorrhage plasma neurophysin I increased 2-25 times and decreased toward basal levels after reinfusion of the blood while plasma neurophysin II was low and showed only minor fluctuations. Neurophysin II was released during parturition and suckling in a pattern similar to that reported for oxytocin release during these events. A rise in plasma neurophysin II occurred towards the end of parturition and spurt release occurred in suckling. The function of neurophysins in the plasma is unknown but porcine neurophysin I has been shown to be released independently into the circulation in response to hemorrhage. Independent release of neurophysin II during parturition and suckling was not demonstrated. In the pig, release of neurophysin I may be associated with vasopressin release and neurophysin II associated with oxytocin release.

RESUMO

Clinical experience with the Omniscience prosthesis from two regional cardiac units in England is presented. Actuarial analysis suggests a prohibitive incidence of prosthetic thrombosis of the mitral valve, this complication occurring in 14 of a total of 96 (15%) patients studied over a mean period of approximately 1 1/2 years. Aortic valve implantations were frequently complicated by prosthetic dehiscence, which occurred in nine of a total of 88 (10%) patients who received this valve. Our results with this prosthesis contrasts markedly with our favorable experience with other types of prostheses and lead us to question the suitability of the Omniscience valve for further clinical use.

RESUMO

Between January 1970 and June 1985, 60 patients underwent surgical repair of postinfarction ventricular septal defect. The preoperative cineangiograms of all patients were reviewed to measure left ventricular ejection fraction and to quantitatively assess right ventricular function by measuring the percentage reduction in right ventricular midcavity diameter. There were 23 early deaths (within 30 days) and 14 late deaths occurring between 1 and 92 months after operation. Of the 23 long-term survivors, 87% are in New York Heart Association Class I or II. The early mortality was significantly higher for inferior infarction (58%) than for anterior infarction (25%). Early mortality was also influenced by the time interval between infarction and operation (under 1 week 41%, over 4 weeks 22%). Early survival was favored by good preoperative right ventricular function; the percentage reduction in right ventricular midcavity diameter was 16.5% +/- 9.5% (mean +/- standard deviation) for the early death group and 26.7% +/- 10.6% for the early survival group. However, the early outcome was not influenced by left ventricular function before operation. Conversely, long-term survival was favored by preserved preoperative left ventricular function; left ventricular ejection fraction was 26.2% +/- 9.3% for the late death group and 35% +/- 8.5% for the late survival group. Long-term survival was not, however, affected by right ventricular function before operation. The results of surgical closure of postinfarction ventricular septal defect have improved between two successive time frames in this series, which is the largest to date.

RESUMO

Saphenous vein coronary artery bypass graft patency can be increased by antiplatelet therapy. Aspirin plus dipyridamole are effective but are associated with tolerability problems. Indobufen is a possible alternative antiplatelet agent that may be better tolerated. A prospective, randomized, double-blind, parallel-group study was undertaken to compare the efficacy and safety of indobufen 200 mg twice daily with aspirin 300 mg thrice daily plus dipyridamole 75 mg thrice daily in preventing occlusion of autologous saphenous vein coronary artery bypass grafts. A total of 803 patients were randomized in the study, of whom 552 had a follow-up coronary angiogram approximately 1 year after operation. All anastomoses were patent in 56% of indobufen-treated patients and 59% of aspirin-dipyridamole recipients (p = 0.384). The percentage of all anastomoses patent was 82% in the indobufen group and 83% in the aspirin-dipyridamole group (p = 0.297). Mean postoperative blood loss was significantly less in the indobufen group (p = 0.043). Patients who received indobufen also had significantly fewer adverse events considered to be treatment-related compared with aspirin-dipyridamole recipients (p = 0.02). At the doses tested indobufen was as effective as aspirin plus dipyridamole in preventing occlusion of saphenous vein grafts and was better tolerated. Because indobufen was associated with less postoperative blood loss it may be used before operation in coronary artery bypass grafting.

RESUMO

AIMS: To determine if there is any correlation between vascular invasion and prognosis in non-small cell carcinoma of the lung; and to look specifically at invasion of vascular channels by tumour cells. METHODS: Eighty seven patients undergoing lobectomy or pneumonectomy for adenocarcinoma or squamous carcinoma were followed up for five years. The histological sections were studied for evidence of vascular invasion using an elastic van Gieson stain. The incidence of intimal fibrosis in arteries and veins was noted and the proportion with vascular invasion evaluated using a scoring system. The presence or absence of lymphatic permeation and tumour necrosis were noted. Survival data were analysed using the log rank test. RESULTS: The overall five year survival was 32%. There were 64 squamous cell carcinomas and 23 adenocarcinomas. Vascular invasion was seen in 77% of patients and lymphatic invasion in 44%. Neither the presence nor absence nor the proportion of blood vessels showing vascular invasion showed any relation to prognosis. Intimal fibrosis and tumour necrosis were unrelated to prognosis. Patients with lymphatic permeation had recurrence and died earlier than those without. CONCLUSION: The presence of arterial or venous invasion by adenocarcinoma or squamous carcinoma of the lung was unrelated to survival; lymphatic permeation was associated with poor prognosis. The two common non-small cell lung cancers behaved differently from other solid tumours, where vascular invasion was a significant factor in determination of prognosis. The presence of intimal fibrosis was unrelated to prognosis.

RESUMO

BACKGROUND: The treatment of sternal wound complications is controversial. It is our practice to combine early aggressive debridement, a modified Robicsek sternal closure, and bilateral pectoralis major advancement flaps with or without closed irrigation in a single procedure. We reviewed our experience to determine the efficacy of this approach. METHODS: Grade II to IV mediastinitis (dehiscence and infection) developed in 47 patients 3 to 14 days after routine open heart operations between 1990 and 1995. Culture-positive infection was identified in 60% (n = 28); 62% (n = 29) had septicemia. Thirty patients underwent incision, drainage, and surgical assessment of the wound. Once systemic signs of infection were under control (no pyrexia, normal white blood cell count), formal single-stage debridement of all infected soft tissues and bones was performed. Sternal stability was achieved using a modified Robicsek closure and bilateral pectoralis major advancement flaps. Seventeen patients were treated with staged procedures. RESULTS: Early sternal closure and coverage with pectoralis major advancement flaps can be associated with a low mortality (0%), low morbidity (13%; n = 4: three superficial wound infections, one seroma), and shortened hospital stay (median, 22 days, compared with a median of 82 days in patients managed with conservative staged treatment; p < 0.05). Sternal stability with excellent functional and aesthetic results has been achieved in all patients. CONCLUSIONS: The combination of aggressive early surgical debridement, sternal closure, and the placement of bilateral pectoralis major advancement flaps is a simple procedure associated with a low mortality and morbidity and a short hospital stay.

RESUMO

To investigate the clinical significance of coronary ostial stenosis, we reviewed eight patients with such lesions, including three with isolated stenosis at the orifice of the coronary artery. There were five male and three female patients, with an average age of 46.25 years (range 32-69 years). Their symptoms consisted mainly of angina (6 patients), with dyspnoea and palpitation being the presenting features in the remaining two patients. All patients underwent preoperative coronary angiography which confirmed stenosis at the level of the orifice with absence of reflux of contrast medium into the sinus of Valsalva as the main features. Delay in the appreciation of stenosis of the orifice of the right coronary artery resulted in the death of two patients, whose diagnosis was confirmed at post mortem examinations. Stenosis of the orifice of the right coronary artery was present in seven patients, with two patients also having stenosis of the orifice of the left coronary artery. The remaining patient had isolated stenosis of the left coronary arterial orifice. Coronary artery bypass grafting was performed in five patients, including two who had patch angioplasty to the right coronary artery. The patient with isolated stenosis of the orifice of the left coronary artery had patch angioplasty only. Follow-up of up to three years in the surviving patients showed good functional results. The ease with which it is possible to miss right coronary ostial stenosis is emphasized and angiographic features are reviewed.

RESUMO

Between January 1980 and December 1986, 2573 patients underwent simple first time coronary artery bypass grafting, of whom 73 (65 males and 8 females) aged 34-69 years (mean 51.3 yrs) had repeat bypass grafts at Wythenshawe Hospital, Manchester. Of these 73 patients, 15 had a previous myocardial infarction, 5 hyperlipidaemia, 4 systemic hypertension, and 12 had a strong family history of ischemic heart disease. There was an overall deterioration of left ventricular function at the time of reoperation. The interval between the two operations was 5-131 months (mean 34.2 mths); recurrence of angina occurred earlier (mean 18.4 mths). Vessels grafted at the first operation were LAD (59), RCA (46), circumflex (41) and diagonal (13). The corresponding data at reoperation were LAD (55), RCA (46), circumflex (28) and diagonal (10). Blocked grafts were seen in 67 patients and new lesions noticed in 29. Reoperation was done using saphenous vein (129), internal mammary artery (5), arm veins (2) and tubular Gortex grafts (2). One patient had concurrent excision of a left ventricular aneurysm. Coronary anastomoses were performed with elective ventricular fibrillation (47) or cardioplegic arrest (91). Aortic cross clamp time varied from 0-92 minutes. Seven patients required intra-aortic balloon support. These patients died in the first 30 days, an operative mortality rate of 4.1%, and two 18 months after surgery. Sixty-eight percent of patients seen at 1 year were totally symptom free. We conclude that reoperation for coronary artery disease can be done with a low mortality and good immediate relief of symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

Amethocaine gel is a recently developed formulation of amethocaine, designed to provide percutaneous local anaesthesia. Its pharmacological characteristics coupled with a phase-change gel formulation may confer therapeutic advantages over existing preparations. Percutaneous local anaesthesia has increasing relevance in analgesia for paediatric procedures and superficial surgical operations.

RESUMO

OBJECTIVES: To determine whether pulmonary rehabilitation carried out in a community setting is more effective than that carried out in a standard hospital setting and which is more cost-effective; also whether telephone follow-up is both cost-effective and useful in prolonging the beneficial effects of a pulmonary rehabilitation programme. DESIGN: A randomised trial. Participants were randomised in 2 x 2 factorial fashion to hospital or community rehabilitation and telephone or standard follow-up with review. SETTING: Hospitals or community sites in Sheffield. The community venues were selected to be close to public transport routes and have good parking and level access. The two hospital venues were the physiotherapy gym and a staff gym within the grounds of the hospital. PARTICIPANTS: Patients with chronic obstructive pulmonary disease diagnosed by respiratory physicians according to Global Initiative for Chronic Obstructive Lung Disease guidelines. INTERVENTIONS: Participants were randomised to one of four groups: hospital rehabilitation with no telephone follow-up; hospital rehabilitation with telephone follow-up; community rehabilitation with no telephone follow-up; or community rehabilitation with telephone follow-up. All were blinded to the telephone intervention arm until 1 month post rehabilitation, when only the assessment team and research participants were unblinded. MAIN OUTCOME MEASURES: The primary outcome measure was the difference in improvement in endurance shuttle walking test (ESWT) between hospital and community pulmonary rehabilitation groups post rehabilitation, and the difference in ESWT during 18 months' follow-up between those receiving telephone encouragement and those receiving standard care. A secondary measure was health-related quality of life. RESULTS: A total of 240 participants had evaluable data. Of these, 129 were randomised to hospital rehabilitation (64 with telephone follow-up and 65 with no telephone follow-up) and 111 to community rehabilitation (55 with telephone follow-up and 56 with no telephone follow-up). For the primary outcome measure, there were 162 patients with data for analysis: hospital rehabilitation with no telephone follow-up (n = 38); hospital rehabilitation with telephone follow-up (n = 48); community rehabilitation with no telephone follow-up (n = 43); and community rehabilitation with telephone follow-up (n = 33). For the acute phase post-rehabilitation outcomes, before patients had the opportunity for telephone follow-up, we compared outcomes between the 76 patients in the community rehabilitation group and the 86 patients in the hospital rehabilitation group. Patients in the hospital rehabilitation group increased the distance they could walk at the post-rehabilitation follow-up by 283 m (SD 360 m), an increase relative to baseline of 109% (SD 137%). Patients in the community rehabilitation group increased the distance they could walk at the post-rehabilitation follow-up by 216 m (SD 340 m), an increase relative to baseline of 91% (SD 133%). There was no statistically significant difference between the groups [17.8% (95% CI -24.3 to 59.9, p = 0.405)]. For longer term outcomes at 6, 12 and 18 months post rehabilitation there was no evidence of a rehabilitation group effect. After allowing for the initial post-rehabilitation baseline distance walked, time (follow-up visit) and the factorial design (telephone follow-up group), the average difference in the post-rehabilitation follow-up distance walked on the ESWT between the hospital and community rehabilitation groups was 1.5 m (95% CI -82.1 to 97.2, p = 0.971), and between the telephone and no-telephone groups it was 56.9 m (95% CI -25.2 to 139, p = 0.174). There was no difference between hospital or community groups in terms of acute effect or persistence of effect. Health economic analysis favoured neither hospital nor community settings, nor did it clearly favour telephone follow-up or routine care. CONCLUSIONS: Pulmonary rehabilitation delivered in a community setting has similar efficacy to that produced in a more traditional hospital-based setting, both settings producing significant improvements in terms of exercise capacity and quality of life acutely and after long-term follow-up. Health economic analysis showed that neither hospital nor community programmes were greatly favoured. The choice of model will depend on local factors of convenience, existing availability of resources and incremental costs. Staff characteristics may be important in gaining optimal outcome, and care should be taken in staff recruitment and training. TRIAL REGISTRATION: Current Controlled Trials ISRCTN86821773.
