Mortality associated with stopping statins in the oldest-old - with and without ischemic heart disease.

ABSTRACT: The association between stopping statins and 1-year mortality in the general population of the oldest-old - with or without ischemic heart disease (IHD) - has been studied herein for the first time.This was a retrospective study. Included were all consecutive patients (n = 369) aged 80 years or more (mean age 87.8 years) hospitalized in a single Geriatrics department during 1 year. The study group included 140 patients in whom statins were stopped upon admission (statin stoppers). The control group included 229 patients who did not use statins in the first place (statin non-users). All-cause 1-year mortality rates were studied in both groups following propensity score matching and in IHD patients separately.Overall, 110 (29.8%) patients died during the year following admission: 38 (27.1%) statin stoppers and 72 (31.4%) statin non-users (P = .498). Cox regression analysis showed no association between stopping statins and 1-year mortality in the crude analysis (hazard ratio [HR] 0.976, 95% confidence interval [CI] 0.651-1.463, P = .907) and following propensity score matching (HR 1.067, 95%CI 0.674-1.689, P = .782). Among 108 IHD patients, 38 (35.2%) patients died during the year following admission: 18 (27.7%) statin stoppers and 20 (46.5%) statin non-users (P = .059). Cox regression analysis showed a nearly significant association between stopping statins (rather than not using statins) in IHD patients and lower 1-year mortality (HR 0.524, 95%CI 0.259-1.060, P = .072).Hence, stopping statins in the general population of the oldest-old - with or without IHD - is possibly safe. Future studies including the oldest-old statin continuers are warranted to confirm this observation.

Urinary retention in diabetic older adults: mortality associated with a urinary catheter inserted during hospitalization but not removed.

PURPOSE: We have studied, in diabetic older adults with urinary retention (UR), whether a urinary catheter (UC) inserted during hospitalization but not removed is associated with 1-year mortality. METHODS: A retrospective study included 327 consecutive older adults (age ≥ 65 years; median age 83 years; 57.8% males) with UR in whom a UC was inserted during hospitalization: 139 (42.5%) diabetics and 188 (57.5%) nondiabetics. UC removal rates during hospitalization and 1-year mortality rates were studied in both groups. Cox regression analysis was used to assess whether a UC inserted during hospitalization but not removed was independently associated with 1-year mortality. RESULTS: Most diabetic and non-diabetic patients left the hospital with a UC (66.2% vs. 75.5%; p = 0.082). Overall, 54 (38.8%) diabetic patients and 52 (27.7%) nondiabetic patients died one year later (OR 1.66; 95% CI 1.04-2.65; p = 0.042). Diabetic patients with a UC at discharge day had significantly higher 1-year mortality rates relative to diabetic patients without a UC (48.9% vs. 19.1%; OR 4.04; 95% CI 1.75-9.30; p = 0.001), while in nondiabetic patients there was no significant difference in 1-year mortality rates between patients with or without a UC at discharge day (26.8% vs. 30.4%; p = 0.705). Cox regression analysis showed that only in diabetic patients a UC not removed was independently associated with 1-year mortality (HR 2.56; 95% CI 1.16-5.64; p = 0.019). CONCLUSION: A UC inserted but not removed in diabetic older adults with UR is associated with 1-year mortality. Removing a UC and its association with mortality should be studied prospectively in this population.

Prerehabilitation alanine aminotransferase blood levels and one-year mortality rates in older adults following hip fracture.

Low alanine aminotransferase (ALT) blood levels prior to rehabilitation are associated with poor function in older adults following hip fracture. We hypothesized that low ALT blood levels prior to rehabilitation were also associated with one-year mortality in this population. Included were 456 older adults (age ≥ 60 years, 82.5% women) admitted for rehabilitation following hip fracture. ALT blood levels were documented between one and six months prior to rehabilitation. Excluded were patients with ALT blood levels over 40 IU/L possibly consistent with liver injury. The main outcome was all-cause mortality one year following rehabilitation admission. The study group included 142 (31.1%) patients with low (≤10 IU/L) ALT blood levels and the control group included 314 (68.9%) patients with high-normal (11-40 IU/L) ALT blood levels. Overall, 52 (11.4%) patients died within one year following rehabilitation admission. Compared with the control group, patients with low ALT blood levels had significantly higher 1-year mortality rates [17.6 vs. 8.6%, odds ratio 2.27, 95% confidence interval (CI) 1.27-4.08]. Cox regression analysis showed that low ALT blood levels prior to rehabilitation were associated with one-year mortality (hazard ratio 1.88, 95% CI 1.08-3.28) together with age (hazard ratio 1.06, 95% CI 1.02-1.11), independent of gender. However, this association was no longer significant following adjustment also for peripheral vascular disease, admission and discharge functional independence measure scores, albumin serum levels, and length of rehabilitation. In conclusion, low ALT blood levels prior to rehabilitation are associated with one-year mortality in older adults following hip fracture. They may be used when only age and gender are known.

Headaches in athletes.

The physician who cares for athletes and physically active patients will encounter various headache syndromes. These symptoms can be debilitating and result in a spectrum of time away from the patient's exercise routines to death. Knowing key symptoms and signs of headache syndromes may lead to faster recovery and be rewarding for both the patient and physician. This article reviews major headache syndromes and their treatment, with attention to those found in patients who participate in competitive sports and lead active lifestyles.

Ethyl chloride as an antipruritic agent: a double-blind placebo-controlled prospective study.

BACKGROUND: Ethyl chloride (EC) is usually used as a topical anesthetic spray agent. However, its antipruritic effects have never been studied, to the best of our knowledge. METHODS: A double-blind placebo-controlled prospective study. Overall, 51 healthy volunteers underwent a histamine skin prick test on both arms in order to trigger local pruritus. Thereafter, the affected areas were treated with an EC spray on one arm and a saline spray (placebo) on the other. Subjects as well as researchers were blind to which sprays were used. Subjects reported improvement in pruritus following EC/placebo and rated the intensity of pruritus by using a validated questionnaire and a visual analog scale. The flare and wheal reactions were measured in both arms before and following treatment with EC/placebo. RESULTS: Significant improvement in pruritus was reported more frequently following treatment with EC compared with placebo (84 vs. 16%; p < 0.0001). Significant reduction in pruritus intensity was reported immediately and 15 min following treatment with EC compared with placebo (p < 0.05). There was no significant difference between EC and placebo in terms of the flare and wheal reactions. CONCLUSIONS: EC is an effective antipruritic agent, and it does not change the wheal and flare reactions, making it ideal for treating pruritus secondary to allergy skin tests without masking their results.

C-reactive protein to distinguish pneumonia from acute decompensated heart failure.

BACKGROUND: Patients with acute decompensated heart failure (ADHF) are frequently treated with unnecessary antibiotics since they are confused with pneumonia patients. AIM: To study the efficacy of measuring C-reactive protein (CRP) levels on admission and CRP velocity in differentiating ADHF from pneumonia. METHODS: A retrospective observational study of ADHF and pneumonia patients admitted to a tertiary hospital during 2 years. Patients who were already treated with antibiotics on admission were excluded. Efficacy of CRP as a diagnostic marker was evaluated by using receiver operator curves (ROC). RESULTS: Overall, 72 ADHF and 50 pneumonia patients were included in the study. The mean CRP levels on admission were 13.5+/-13.5 mg/L for the ADHF patients and 127+/-84 mg/L for the pneumonia patients (p<0.001). CRP increases of > or =0.56 mg/L/h were diagnostic of pneumonia. CRP levels on admission together with CRP increases had a sensitivity of 0.96 and a specificity of 0.972 (p<0.001) as markers to distinguish pneumonia from ADHF. CONCLUSIONS: This study emphasizes the dynamic nature of biomarkers. Demonstrating the efficiency of repeated CRP measurements in an acute setting will provide clinicians with a valuable tool for establishing the correct diagnosis and refraining from unnecessary use of antibiotics.

Takotsubo cardiomyopathy and QT interval prolongation: who are the patients at risk for torsades de pointes?

OBJECTIVES: QT interval prolongation is prevalent among patients with Takotsubo cardiomyopathy (TC), whereas torsades de pointes (TdP) has rarely been reported in these patients. We studied all peer-reviewed reports on TC-associated QT interval prolongation and all peer-reviewed reports on TC-associated TdP to characterize the clinical circumstances leading to TdP in patients with TC. METHODS: The literature search yielded 14 reports on TC-associated TdP and 26 reports on TC-associated QT interval prolongation. Overall, 15 patients with TC-associated TdP and 86 patients with TC-associated QT interval prolongation were reported. We systematically reviewed each report and recorded the risk factors for TdP as well as the clinical circumstances of TC. RESULTS: The prevalence of the male sex was higher among patients with TC-associated TdP relative to patients with TC-associated QT interval prolongation (26.7% vs 5.8%; P = .01). There was a trend in the mean maximal corrected QT interval being longer among patients with TC-associated TdP relative to patients with TC-associated QT interval prolongation (679.9 +/- 230.6 vs 555.9 +/- 63.8 milliseconds; P = .06). There were no differences between patients with TC-associated TdP and patients with TC-associated QT interval prolongation in mean age, maximal troponin levels, and lowest ejection fraction. Overall, 12 (80.0%) patients with TC-associated TdP had risk factors for TdP other than the female sex and systolic dysfunction, including suspicion of congenital long QT syndrome, bradycardia, hypokalemia, recent conversion from atrial fibrillation to sinus rhythm, and using QT prolonging agents. CONCLUSIONS: Men with TC-associated QT interval prolongation are at risk for TdP. Most patients with TC-associated TdP have risk factors for TdP other than the female sex and systolic dysfunction.

Drug-induced torsades de pointes in patients aged 80 years or more.

OBJECTIVE: We studied all English-written peer-reviewed reports on drug-induced torsades de pointes (TdP) in patients aged 80 years or more in order to characterize the clinical circumstances leading to this serious complication. METHODS: Our literature search yielded 24 reports on 25 patients aged 80-95 years with drug-induced TdP. We systematically reviewed each report and recorded the non-modifiable risk factors for drug-induced TdP (i.e., female sex and structural heart disease) as well as preventable clinical circumstances, which might have been associated with drug-induced TdP. RESULTS: The most prevalent risk factors for drug-induced TdP were non-modifiable risk factors: 22 (88%) patients were female patients and 19 (76%) patients had structural heart disease. Overall, 16 (64%) patients were female patients with structural heart disease. The literature did not report any elderly male patients without structural heart disease. Among the preventable clinical circumstances, which might have been associated with drug-induced TdP, the most prevalent were: administrating QT prolonging agents despite long QT interval (n=11; 44%) and co-administration of two or more QT prolonging agents (n=9; 36%). The most prevalent QT prolonging agents found to trigger TdP were macrolides and quinolones (n=9; 36%). All but three patients had at least one or more preventable clinical circumstances, which might have been associated with drug-induced TdP. CONCLUSION: Physicians should be more aware of the risk for drug-induced TdP in patients aged 80 years or more while administrating QT prolonging agents despite long QT interval and co- administrating two or more QT prolonging agents, specifically in elderly female patients with structural heart disease.

Treatment of osteochondritis dissecans of the ankle with hyaluronic acid injections: a prospective study.

BACKGROUND: No studies have evaluated the efficacy of hyaluronic acid (HA) in reducing pain caused by osteochondritis dissecans (OCD) of the ankle. We report our initial results with this treatment. MATERIALS AND METHODS: Fifteen subjects aged 18 to 60 treated for OCD of the talus were followed for 26 weeks, in a pre- and post-treatment repeated measurements design, after receiving three weekly injections of intra-articular HA. The efficacy of HA injections in reducing pain and improving function was assessed at each visit and adverse events were recorded. Efficacy was evaluated by comparing scores determined using a Visual Analog Scale for pain, stiffness and function over time with baseline values. In addition, frequency of symptoms and global function over time were assessed using questionnaires and the AOFAS Ankle-Hindfoot Scale. Data analysis was made using ANCOVA models and paired t-tests. All statistical tests were based on an alpha level of 0.05. RESULTS: The majority of subjects were male (60%) and had Grade 3 lesions (60%). Mean VAS scores, reported on a scale from 1 (e.g., no pain) to 10 (e.g., worst pain) decreased for pain (5.6 to 3.2), stiffness (5.1 to 2.9), and function (5.9 to 3.3) from baseline to week 26. Subjective global function scores, reported on a scale from 0 to 100 (with 100 representing healthy, pre-injury function), improved on average from 57.3 at baseline to 74.3 by week 26. All of these results were statistically significant, as was the decrease in frequency of pain reported by subjects at the end of the study. CONCLUSION: OCD of the ankle treated with intra-articular injections of HA caused a decrease in pain scores and increase in global functioning over a short period of time (within 12 weeks) which then lasted for more than 6 months with minimal adverse events.

The minority of young adult men with sexual disorders seek medical treatment.

INTRODUCTION: The Israel Defense Force (IDF) conducts screening examinations of military personnel aimed at early detection of morbidities, including erectile dysfunction (ED) and other sexual disorders (SDs). Men with SDs are referred to the IDF's sex clinic for consultation. AIM: We present the long-term compliance of military men with SDs to the screening program. MAIN OUTCOME MEASURES: We investigated how many men screened for ED and other SDs turned to the IDF's sex clinic for consultation. METHODS: Subjects 25-50 years old performed screening examinations at the Staff Periodic Examination Center. The Sexual Health Inventory for Men (SHIM) questionnaire was used to categorize ED. The IDF's sex clinic records were investigated. RESULTS: During 2001-2003, 5,836 men completed the SHIM questionnaire. Overall, 1,570 (26.9%) men had low SHIM scores suggesting ED and other SDs. Although only 76 (4.8%) of these men turned to the IDF's sex clinic over these years, more men conferred with the IDF's sexologist every year, and more men were referred by their primary-care physicians to the IDF's sex clinic regardless of their SHIM score. CONCLUSIONS: Screening for SDs in young adult men is not enough; encouraging young adult men screened for SDs to turn to a sex clinic for evaluation is the true challenge. Nevertheless, adding a sexual questionnaire to screening examinations may raise the awareness of sexual issues in both the patients and their primary-care physicians.

The prevalence of erectile dysfunction among hypertensive and prehypertensive men aged 25-40 years.

INTRODUCTION: Erectile dysfunction (ED) and hypertension (HTN) are common and associated among men aged 40-70 years. Data on the prevalence of ED among younger hypertensive and prehypertensive men are limited. AIM: To study the prevalence of ED in a large-scale population of hypertensive and prehypertensive men aged 25-40 years. MAIN OUTCOME MEASURES: ED severity, systolic blood pressures (SBPs), diastolic blood pressures (DBPs), and mean arterial blood pressures (MAPs). METHODS: Israel Defense Force personnel, aged 25 years and older, go through routine health checks at the Staff Periodic Health Examination Center (SPEC) every 3-5 years, including measuring blood pressure and completing the Sexual Health Inventory for Men (SHIM) questionnaire in order to detect HTN and ED, respectively, and assess its severity. Pre-HTN was defined as SBP 120-139 mm Hg or DBP 80-89 mm Hg. HTN was defined as SBP >/or140 mm Hg and/or DBP >or=90 mm Hg. RESULTS: During 2001-2004, an overall of 11,252 men, aged 25-40 years, reported to the SPEC, and 5,860 (52.1%) men filled out the SHIM questionnaire. Among responders to the SHIM questionnaire, 1,278 (21.8%) men had low scores (

Erectile dysfunction severity might be associated with poor cardiovascular prognosis in diabetic men.

INTRODUCTION: Although erectile dysfunction (ED) might be associated with coronary heart disease (CHD), there is no evidence it predicts poor cardiovascular prognosis. On the other hand, an abnormal heart rate profile during exercise stress testing predicts poor cardiovascular prognosis in high-risk patients, such as diabetic men, even in the absence of CHD. AIM: In order to study if ED predicts poor cardiovascular prognosis in high-risk patients, we examined the association between ED and heart rate profile during exercise stress testing in diabetic men with no CHD. MAIN OUTCOME MEASURES: Erectile dysfunction severity, exercise capacity during exercise stress testing, and heart rate decrease after exercise stress testing. METHODS: A retrospective study. The medical charts of diabetic men with vascular ED from a single-sex clinic were reviewed, as well as the medical charts of body mass index (BMI)- and age-matched diabetic men without ED going through routine check-ups. All men underwent routine treadmill stress testing according to the Bruce protocol in order to characterize heart rate profile during exercise. The Sexual Health Inventory for Men (SHIM) questionnaire was used to characterize ED. RESULTS: Included were 18 diabetic men with ED (SHIM questionnaire scores 5-21) and 18 diabetic men without ED (SHIM questionnaire scores 22-25), 40 years of age or older. None of the men had signs of coronary insufficiency during exercise treadmill stress testing. Although the two groups did not statistically differ with respect to the mean age, the mean BMI, the prevalence of cardiovascular risk factors, and the mean exercise treadmill stress testing findings, the SHIM questionnaire scores were significantly associated with low metabolic equivalents (r = 0.51, P = 0.03) and delayed heart rate recovery during the first 2 minutes after exercise (r = 0.55, P = 0.018) only among diabetic men with ED. CONCLUSIONS: Erectile dysfunction severity might be associated with poor cardiovascular prognosis in adult diabetic men with no CHD.

QT prolongation and Torsades de Pointes in patients previously treated with anthracyclines.

Anthracyclines reduce myocardial repolarization reserve and might increase the risk for Torsades de Pointes a long time after treatment. We studied all the publications concerning Torsades de Pointes in patients previously treated with anthracyclines to investigate the clinical circumstances leading to this rare life-threatening complication. Our literature search yielded nine reports of 11 patients who had developed Torsades de Pointes anywhere from weeks to years following treatment with anthracyclines. One of the patients was hospitalized in our medical center. Risk factors and triggers for Torsades de Pointes, among other clinical aspects, were analyzed in each report. Most patients (n=10; 90.9%) were previously treated with anthracyclines owing to acute leukemias: acute myelogenous leukemia (n=5), acute lymphocytic leukemia (n=3) and acute promyelocytic leukemia (n=2). One patient was previously treated with anthracyclines owing to Hodgkin's lymphoma. Most patients were women (n=9; 81.8%). The most prevalent triggers for Torsades de Pointes were the administration of a QT-prolonging agent (n=10; 90.9%) and hypokalemia (n=9; 81.8%). Azole derivatives were the most prevalent of the QT-prolonging agents that triggered Torsades de Pointes (n=5; 45.5%). Although four patients suffered from anthracycline-induced left ventricular dysfunction and five other patients had only one or two questionable triggers for Torsades de Pointes, in only two of these cases the authors considered previous treatment with anthracyclines as a risk factor for Torsades de Pointes. Previous treatment with anthracycline is an underestimated risk factor for Torsades de Pointes. Possible triggers includes azole derivatives, other QT-prolonging agents and hypokalemia. Women patients are particularly at risk.

The prevalence of reversible cardiovascular risk factors in Israelis aged 25-55 years.

BACKGROUND: Coronary heart disease is a major cause of morbidity and mortality worldwide. Early detection of cardiovascular risk factors and intervention may reduce consequential morbidity and mortality. OBJECTIVES: To assess the prevalence of reversible and treatable cardiovascular risk factors among 26,477 healthy Israeli adults: 23,339 men and 3138 women aged 25-55 years. METHODS: We collected data during routine examinations performed as part of a screening program for Israel Defense Force personnel. RESULTS: The three most prevalent cardiovascular risk factors were a sedentary lifestyle (64%), dyslipidemia (55.1%) and smoking (26.8%). Overall, 52.9% of the men and 48.4% of the women had two or more cardiovascular risk factors. Moreover, 52.4% of young adult men and 43.3% of young adult women, age 25-34 years, had two or more reversible cardiovascular risk factors. CONCLUSIONS: In this expectedly healthy population there was a high prevalence of reversible and treatable cardiovascular risk factors in both genders and in young ages. These observations stress the need for routine health examinations and lifestyle modification programs even in the young healthy Israeli population.
