Long‐term followup for rheumatoid arthritis patients in a multicenter outcomes study of silicone metacarpophalangeal joint arthroplasty

Objective Rheumatoid arthritis (RA) often results in deformities at the metacarpophalangeal (MCP) joints. Patients with severe deformities can be treated by silicone metacarpophalangeal joint arthroplasty (SMPA). The objective of the study is to prospectively compare long‐term outcomes for an SMPA surgical and a nonsurgical cohort of RA patients. Methods A total of 67 surgical and 95 nonsurgical patients with severe subluxation and/or ulnar drift of the fingers at the MCP joints were recruited from 2004–2008 in this multicenter prospective cohort study. Patients could elect to undergo SMPA or not. Outcomes included the Michigan Hand Outcomes Questionnaire (MHQ), Arthritis Impact Measurement Scales 2 (AIMS2), grip/pinch strength, Jebsen‐Taylor Test, ulnar deviation, extensor lag, and arc of motion measurements at the MCP joints. Results There was no significant difference in the mean age, race, education, and income at baseline between the 2 groups. Surgical subjects had worse MHQ function and functional measurements at baseline. At 3 years, the mean overall MHQ score and the MHQ function, activities of daily living, aesthetics, and satisfaction scores showed significant improvement in the surgical group compared to the nonsurgical group. Ulnar deviation, extensor lag, and arc of motion in the MCP and proximal interphalangeal joints also improved significantly in the surgical group. No improvement was seen in the mean AIMS2 scores and grip/pinch strength. Complications were minimal with a fracture rate of 9.5%. Conclusion RA patients with poor baseline functioning showed long‐term improvement in hand function and appearance following treatment with SMPA compared to nonsurgical controls.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/93508/1/21705_ftp.pd

Association between age and access to immediate breast reconstruction in women undergoing mastectomy for breast cancer.

BACKGROUND: National guidelines state that patients with breast cancer undergoing mastectomy in England should be offered immediate breast reconstruction (IR), unless precluded by their fitness for surgery or the need for adjuvant therapies. METHODS: A national study investigated factors that influenced clinicians' decision to offer IR, and collected data on case mix, operative procedures and reconstructive decision-making among women with breast cancer having a mastectomy with or without IR in the English National Health Service between 1 January 2008 and 31 March 2009. Multivariable logistic regression was used to examine the relationship between whether or not women were offered IR and their characteristics (tumour burden, functional status, planned radiotherapy, planned chemotherapy, perioperative fitness, obesity, smoking status and age). RESULTS: Of 13 225 women, 6458 (48·8 per cent) were offered IR. Among factors the guidelines highlighted as relevant to decision-making, the three most strongly associated with the likelihood of an offer were tumour burden, planned radiotherapy and performance status. Depending on the combination of their values, the probability of an IR offer ranged from 7·4 to 85·1 per cent. A regression model that included all available factors discriminated well between whether or not women were offered IR (c-statistic 0·773), but revealed that increasing age was associated with a fall in the probability of an IR offer beyond that expected from older patients' tumour and co-morbidity characteristics. CONCLUSION: Clinicians are broadly following guidance on the offer of IR, except with respect to patients' age

Coronary angiography and angioplasty in diabetic patients

Screening, diagnosis and revascularization of coronary artery disease (CAD) in type 2 diabetes mellitus are major challenges for current clinical practice. Diagnostic (angiography) and therapeutic (angioplasty) cardiac catheterization are important resources for the clinical assessment and management of coronary atherosclerosis. Anatomic peculiarities of CAD in diabetics can be well characterized by angiography, associated or not by intravascular ultrasound. The worse outcome following coronary revascularization procedures, either angioplasty or surgery, in diabetic is one of the main fields of clinical research. In spite of controversies, about one quarter of angioplasty and one third of surgical revascularization procedures are performed in diabetics. Two ongoing, large, randomized, multicentric trials are investigating the best management of CAD in diabetics. The BARI 2D trial is randomizing asymptomatic or mildly symptomatic patients with CAD for either medical therapy or revascularization (angioplasty or surgery, according to the best clinical judgment). The FREEDOM trial is randomizing stable patients with multivessel CAD for either angioplasty with drug eluting stents or surgery, with or without extracorporeal circulation. While the evidences are not available, in order to decide on the best revascularization procedure for individual patients, medical practice has been balanced according to a number of variables. Conditions that favor angioplasty: short lesions, lesions in large vessels, absence of left anterior descending artery disease, previous coronary bypass surgery and high surgical risk due to co-morbidities. Conditions that favor surgery: long lesions, lesions in small vessels, presence of left anterior descending artery disease and need for associated valve surgery.O rastreamento, o diagnóstico e a revascularização da doença arterial coronária (DAC) no diabetes tipo 2 representam enormes desafios para a prática médica. Neste contexto, o cateterismo cardíaco diagnóstico (angiografia) e terapêutico (angioplastia) são recursos fundamentais na avaliação clínica e manejo da aterosclerose coronária. Avaliações das particularidades anatômicas da DAC no diabetes são detalhadamente caracterizadas pela angiografia coronária, associada ou não ao ultra-som intracoronário. Por outro lado, a resposta pior aos procedimentos de revascularização (angioplastia e cirurgia) da DAC nos diabéticos representa umas das áreas de maior investigação clínica contemporânea. A despeito das controvérsias, cerca de um quarto dos pacientes submetidos a angioplastia e um terço dos pacientes submetidos a cirurgia são diabéticos. Dois grandes estudos multicêntricos randomizados, em andamento, investigam o melhor manejo da DAC nos diabéticos. O BARI 2D está randomizando pacientes com DAC assintomáticos ou com sintomas leves para tratamento clínico ou revascularização (angioplastia ou cirurgia, conforme melhor julgamento clínico). O FREEDOM está randomizando pacientes diabéticos estáveis com DAC multiarterial, para angioplastia com stent farmacológico ou cirurgia, com ou sem uso de circulação extra-corpórea. Enquanto as evidências não estão disponíveis, a prática médica atual é balanceada por um conjunto de variáveis na decisão sobre a melhor alternativa de revascularização. Condições que favorecem a angioplastia: estenoses curtas, vasos grandes, ausência de estenose na artéria descendente anterior (ADA), cirurgia de revascularização prévia e risco cirúrgico elevado. Condições que favorecem a indicação de cirurgia: estenoses longas, vasos pequenos, presença de estenose da ADA e cirurgia valvar associada.UNIFESP-EPMSPDM Hospital São Paulo Serviço de Hemodinâmica e Cardiologia IntervencionistaFOR Hospital do Rim e HipertensãoUNIFESP, EPMSPDM Hospital São Paulo Serviço de Hemodinâmica e Cardiologia IntervencionistaSciEL

Cardiovascular magnetic resonance imaging of myocardial oedema following acute myocardial infarction: Is whole heart coverage necessary?

© 2016 Hamshere et al. Background: AAR measurement is useful when assessing the efficacy of reperfusion therapy and novel cardioprotective agents after myocardial infarction. Multi-slice (Typically 10-12) T2-STIR has been used widely for its measurement, typically with a short axis stack (SAX) covering the entire left ventricle, which can result in long acquisition times and multiple breath holds. This study sought to compare 3-slice T2-short-tau inversion recovery (T2- STIR) technique against conventional multi-slice T2-STIR technique for the assessment of area at risk (AAR). Methods: CMR imaging was performed on 167 patients after successful primary percutaneous coronary intervention. 82 patients underwent a novel 3-slice SAX protocol and 85 patients underwent standard 10-slice SAX protocol. AAR was obtained by manual endocardial and epicardial contour mapping followed by a semi- automated selection of normal myocardium; the volume was expressed as mass (%) by two independent observers. Results: 85 patients underwent both 10-slice and 3-slice imaging assessment showing a significant and strong correlation (intraclass correlation coefficient = 0.92;p < 0.0001) and a low Bland-Altman limit (mean difference -0.03 ± 3.21 %, 95 % limit of agreement,- 6.3 to 6.3) between the 2 analysis techniques. A further 82 patients underwent 3-slice imaging alone, both the 3-slice and the 10-slice techniques showed statistically significant correlations with angiographic risk scores (3-slice to BARI r = 0.36, 3-slice to APPROACH r = 0.42, 10-slice to BARI r = 0.27, 10-slice to APPROACH r = 0.46). There was low inter-observer variability demonstrated in the 3-slice technique, which was comparable to the 10-slice method (z = 1.035, p = 0.15). Acquisition and analysis times were quicker in the 3-slice compared to the 10-slice method (3-slice median time: 100 seconds (IQR: 65-171 s) vs (10-slice time: 355 seconds (IQR: 275-603 s); p < 0.0001. Conclusions: AAR measured using 3-slice T2-STIR technique correlates well with standard 10-slice techniques, with no significant bias demonstrated in assessing the AAR. The 3-slice technique requires less time to perform and analyse and is therefore advantageous for both patients and clinicians

Revascularization for coronary artery disease in diabetes mellitus: Angioplasty, stents and coronary artery bypass grafting

Author Manuscript: 2011 April 14Patients with diabetes mellitus (DM) are prone to a diffuse and rapidly progressive form of atherosclerosis, which increases their likelihood of requiring revascularization. However, the unique pathophysiology of atherosclerosis in patients with DM modifies the response to arterial injury, with profound clinical consequences for patients undergoing percutaneous coronary intervention (PCI). Multiple studies have shown that DM is a strong risk factor for restenosis following successful balloon angioplasty or coronary stenting, with greater need for repeat revascularization and inferior clinical outcomes. Early data suggest that drug eluting stents reduce restenosis rates and the need for repeat revascularization irrespective of the diabetic state and with no significant reduction in hard clinical endpoints such as myocardial infarction and mortality. For many patients with 1- or 2-vessel coronary artery disease, there is little prognostic benefit from any intervention over optimal medical therapy. PCI with drug-eluting or bare metal stents is appropriate for patients who remain symptomatic with medical therapy. However, selection of the optimal myocardial revascularization strategy for patients with DM and multivessel coronary artery disease is crucial. Randomized trials comparing multivessel PCI with balloon angioplasty or bare metal stents to coronary artery bypass grafting (CABG) consistently demonstrated the superiority of CABG in patients with treated DM. In the setting of diabetes CABG had greater survival, fewer recurrent infarctions or need for re-intervention. Limited data suggests that CABG is superior to multivessel PCI even when drug-eluting stents are used. Several ongoing randomized trials are evaluating the long-term comparative efficacy of PCI with drug-eluting stents and CABG in patients with DM. Only further study will continue to unravel the mechanisms at play and optimal therapy in the face of the profoundly virulent atherosclerotic potential that accompanies diabetes mellitus.National Institutes of Health (U.S.) (GM 49039

Can local application of Tranexamic acid reduce post-coronary bypass surgery blood loss? A randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Diffuse microvascular bleeding remains a common problem after cardiac procedures.</p> <p>Systemic use of antifibrinolytic reduces the postoperative blood loss.</p> <p>The purpose of this study was to examine the effectiveness of local application of tranexamic acid to reduce blood loss after coronary artery bypass grafting (CABG).</p> <p>Methods</p> <p>Thirty eight patients scheduled for primary isolated coronary artery bypass grafting were included in this double blind, prospective, randomized, placebo controlled study.</p> <p>Tranexamic acid (TA) group (19 patients) received 1 gram of TA diluted in 100 ml normal saline. Placebo group (19 patients) received 100 ml of normal saline only. The solution was purred in the pericardial and mediastinal cavities.</p> <p>Results</p> <p>Both groups were comparable in their baseline demographic and surgical characteristics. During the first 24 hours post-operatively, cumulative blood loss was significantly less in TA group (median of 626 ml) compared to Placebo group (median of 1040 ml) (P = 0.04). There was no significant difference in the post-op Packed RBCs transfusion between both groups (median of one unit in each) (P = 0.82). Significant less platelets transfusion required in TA group (median zero unit) than in placebo group (median 2 units) (P = 0.03).

Cardiac Procedures among American Indians and Alaska Natives compared to Non-Hispanic Whites Hospitalized with Ischemic Heart Disease in California

BackgroundAmerican Indians/Alaska Natives (AIAN) experience a high burden of cardiovascular disease with rates for fatal and nonfatal heart disease approximately twofold higher than the U.S. population.ObjectiveTo determine if disparities exist in cardiac procedure rates among AIAN compared to non-Hispanic whites hospitalized in California for ischemic heart disease defined as acute myocardial infarction or unstable angina.DesignCross-sectional study. EVENTS: A total of 796 ischemic heart disease hospitalizations among AIAN and 90971 among non-Hispanic whites in 37 of 58 counties in California from 1998-2002.MeasurementsCardiac catheterization, percutaneous cardiac intervention, and coronary artery bypass graft surgery procedure rates from hospitalization administrative data.Main resultsAIAN did not have lower cardiac procedure rates for cardiac catheterization and percutaneous cardiac intervention compared to non-Hispanic whites (unadjusted OR 1.00, 95% CI 0.87-1.16 and OR 1.04, 95% CI 0.90-1.20, respectively). Adjustment for age, sex, comorbidities, and payer source did not alter the results (adjusted OR 0.95, 95% CI 0.82-1.10 and OR 0.98, 95% CI 0.85-1.14, respectively). We found higher odds (unadjusted OR 1.36, 95% CI 1.09-1.70) for receipt of coronary artery bypass graft surgery among AIAN hospitalized for ischemic heart disease compared to non-Hispanic whites which after adjustment attenuated some and was no longer statistically significant (adjusted OR 1.26, 95% CI 1.00-1.58).ConclusionAIAN were not less likely to receive cardiac procedures as non-Hispanic whites during hospitalizations for ischemic heart disease. Additional research is needed to determine whether differences in specialty referral patterns, patients' treatment preferences, or outpatient management may explain some of the health disparities due to cardiovascular disease that is found among AIAN

Five-year follow-up of angiographic disease progression after medicine, angioplasty, or surgery

<p>Abstract</p> <p>Background</p> <p>Progression of atherosclerosis in coronary artery disease is observed through consecutive angiograms. Prognosis of this progression in patients randomized to different treatments has not been established. This study compared progression of coronary artery disease in native coronary arteries in patients undergoing surgery, angioplasty, or medical treatment.</p> <p>Methods</p> <p>Patients (611) with stable multivessel coronary artery disease and preserved ventricular function were randomly assigned to CABG, PCI, or medical treatment alone (MT). After 5-year follow-up, 392 patients (64%) underwent new angiography. Progression was considered a new stenosis of ≥ 50% in an arterial segment previously considered normal or an increased grade of previous stenosis > 20% in nontreated vessels.</p> <p>Results</p> <p>Of the 392 patients, 136 underwent CABG, 146 PCI, and 110 MT. Baseline characteristics were similar among treatment groups, except for more smokers and statin users in the MT group, more hypertensives and lower LDL-cholesterol levels in the CABG group, and more angina in the PCI group at study entry. Analysis showed greater progression in at least one native vessel in PCI patients (84%) compared with CABG (57%) and MT (74%) patients (p < 0.001). LAD coronary territory had higher progression compared with LCX and RCA (P < 0.001). PCI treatment, hypertension, male sex, and previous MI were independent risk factors for progression. No statistical difference existed between coronary events and the development of progression.</p> <p>Conclusion</p> <p>The angioplasty treatment conferred greater progression in native coronary arteries, especially in the left anterior descending territories and treated vessels. The progression was independently associated with hypertension, male sex, and previous myocardial infarction.</p
