Frequency Of Development Of Connective Tissue Disease In Statin-Users Versus Nonusers
Statins have pleiotropic properties that may affect the development of connective tissue diseases (CTD). The objective of this study was to compare the risk of CTD diagnoses in statin users and nonusers. This study was a propensity score-matched analysis of adult patients (30 to 85 years old) in the San Antonio military medical community. The study was divided into baseline (October 1, 2003 to September 30, 2005), and follow-up (October 1, 2005 to March 5, 2010) periods. Statin users received a statin prescription during fiscal year 2005. Nonusers did not receive a statin at any time during the study. The outcome measure was the occurrence of 3 diagnosis codes of the International Classification of Diseases, 9th Revision, Clinical Modification consistent with CTD. We described co-morbidities during the baseline period using the Charlson Comorbidity Index. We created a propensity score based on 41 variables. We then matched statin users and nonusers 1:1, using a caliper of 0.001. Of 46,488 patients who met study criteria (13,640 statin users and 32,848 nonusers), we matched 6,956 pairs of statin users and nonusers. Matched groups were similar in terms of patient age, gender, incidence of co-morbidities, total Charlson Comorbidity Index, health care use, and medication use. The odds ratio for CTD was lower in statin users than nonusers (odds ratio: 0.80; 95% confidence interval: 0.64 to 0.99; p = 0.05). Secondary analysis and sensitivity analysis confirmed these results. In conclusion, statin use was associated with a lower risk of CTD. Published by Elsevier Inc.Pharmac
The Effect of Statin Therapy on the Incidence of Infections: A Retrospective Cohort Analysis
Statins have been postulated to prevent infection through immunomodulatory effects
The Clot Thickens: Diagnosing Acute Pulmonary Embolism as a Trigger for Chronic Obstructive Pulmonary Disease Exacerbation in the Setting of Anticoagulation Failure
Chronic obstructive pulmonary disease (COPD) exacerbations are most commonly triggered by infections, but up to 25% of those that require hospitalization are thought to be triggered by acute pulmonary embolism. We present the case of a 71-year-old patient with a history of unprovoked pulmonary embolisms on anticoagulation therapy hospitalized for a COPD exacerbation. The exacerbation was triggered by an acute pulmonary embolism, representing anticoagulation failure
Preoperative medical consultation: maximizing its benefits
Background: The increasing complexity of medical and surgical care often demands comprehensive preoperative work-ups by medical consultants and detailed management recommendations to optimize the patient\u27s medical ailments before surgery. This article aims to review the available evidence and discuss elements of the preoperative medical consultation that are of particular relevance to surgeons.
Methods: The authors performed a comprehensive review of the available medical literature and guidelines pertaining to preoperative medical management and present a narrative summary of their findings.
Results: Although many preoperative recommendations are based on expert opinion and consensus, a growing number of studies and clinical practice guidelines provides direction as to what is the best management of patients with medical problems before surgery.
Conclusions: Collaborative efforts and adequate communication between the medical and surgical teams are necessary to ensure appropriate patient management before surgery. Although higher-risk patients may require thorough preoperative evaluations, extensive routine investigations may not always be necessary
Comparison Of The Risk Of Psychological And Cognitive Disorders Between Persistent And Nonpersistent Statin Users
Despite their cardiovascular benefits, statin use has been associated with a wide array of actual or perceived psychological and cognitive adverse events. The objective of this study was to compare baseline characteristics and the risk of developing psychological and cognitive disorders between persistent and nonpersistent statin users. We performed a retrospective cohort study (October 1, 2003, to March 1, 2010) of 13,626 statin users in a regional US military health-care system. The persistence of statin use was defined by cumulative pharmacy fill data. Outcomes were the occurrence of psychological diseases during follow-up using prespecified groups based on International Classification of Diseases, Ninth Revision, codes: (1) schizophrenia and psychosis, (2) major depression and bipolar disorders, (3) all psychological diseases, and (4) dementia and cognitive disorders. Statin users who were nonpersistent at 2 years were younger, less likely to be men, and had fewer co-morbidities than persistent users. They were also more likely to be diagnosed with schizophrenia or psychosis (odds ratio [OR] 1.58, 95% confidence interval [CI] 1.20 to 2.10) and cognitive disorders (OR 1.56, 95% CI 1.19 to 2.03) during follow-up compared with persistent users. There was not an association between nonpersistence at 2 years and the development of depression and bipolar disorders (OR 0.99,95% CI 0.85 to 1.15) or combined psychological diseases (OR 0.97, 95% CI 0.86 to 1.09). Cumulative persistence with statin therapy as a continuous measure was associated with less risk of all outcomes. In conclusion, persistent statin users did not demonstrate an increase in the diagnosis of psychological disorders compared with nonpersistent users. Nonpersistent statin use was associated with a greater likelihood of being diagnosed with psychotic or cognitive disorders. Published by Elsevier Inc.Pharmac
Statins and renal disease progression, ophthalmic manifestations, and neurological manifestations in veterans with diabetes: A retrospective cohort study.
BackgroundStatins increase insulin resistance, which may increase risk of diabetic microvascular complications. Little is known about the impact of statins on renal, ophthalmologic, and neurologic complications of diabetes in practice. The objective of this study was to examine the association of statins with renal disease progression, ophthalmic manifestations, and neurological manifestations in diabetes.MethodsThis is a retrospective cohort study, new-user active comparator design, that included a national Veterans Health Administration (VA) patients with diabetes from 2003 to 2015. Patients were age 30 years or older and were regular users of the VA with data encompassing clinical encounters, demographics, vital signs, laboratory tests, and medications. Patients were divided into statin users or nonusers (active comparators). Statin users initiated statins and nonusers initiated H2-blockers or proton pump-inhibitors (H2-PPI) as an active comparator. Study outcomes were: 1) Composite renal disease progression outcome; 2) Incident diabetes with ophthalmic manifestations; and 3) Incident diabetes with neurological manifestations.ResultsOut of 705,774 eligible patients, we propensity score matched 81,146 pairs of statin users and active comparators. Over a mean (standard deviation) of follow up duration of 4.8 (3) years, renal disease progression occurred in 9.5% of statin users vs 8.3% of nonusers (odds ratio [OR]: 1.16; 95% confidence interval [95%CI]: 1.12-1.20), incident ophthalmic manifestations in 2.7% of statin users vs 2.0% of nonusers (OR: 1.35, 95%CI:1.27-1.44), and incident neurological manifestations in 6.7% of statin users vs 5.7% of nonusers (OR: 1.19, 95%CI:1.15-1.25). Secondary, sensitivity, and post-hoc analyses were consistent and demonstrated highest risks among the healthier subgroup and those with intensive lowering of LDL-cholesterol.ConclusionsStatin use in patients with diabetes was associated with modestly higher risk of renal disease progression, incident ophthalmic, and neurological manifestations. More research is needed to assess the overall harm/benefit balance for statins in the lower risk populations with diabetes and those who receive intensive statin therapy
