Bilateral simultaneous intertrochanteric fractures of femur without major trauma

Bilateral simultaneous intertrochanteric femur fractures are rare and usually occur as a result of major trauma. In this paper, we present a 76-year old male patient from Turkey referred to the emergency service of our hospital with severe pain and poor mobilization in both hips. There was no history of major trauma. The patient was treated with closed proximal femoral nailing in both hips in the same operation period. At last follow-up, 6 months after surgery, the patient was able to walk with the aid of his children and resumed his previous status, after he had completed an intensive rehabilitation program.

Cost-Effectiveness Analysis of a Television Campaign to Promote Seasonal Influenza Vaccination Among the Elderly

BACKGROUND

The U.S. policy goals regarding influenza vaccination coverage rate among the elderly include the increase in the coverage rate and the elimination of disparities across racial/ethnic groups.

OBJECTIVE

To examine the potential effectiveness of a television (TV) campaign to increase seasonal influenza vaccination among the elderly.

METHODS

We estimated the incremental cost-effectiveness ratio (ICER, defined as incremental cost per additionally vaccinated Medicare individual) of a hypothetical nationwide TV campaign for influenza vaccination compared with no campaign. We measured the effectiveness of the nationwide TV campaign (advertised once a week at prime time for 30 seconds) during a 17-week influenza vaccination season among four racial/ethnic elderly groups (N=39 million): non-Hispanic white (W), non-Hispanic African American (AA), English-speaking Hispanic (EH), and Spanish-speaking Hispanic (SH).

RESULTS

The hypothetical campaign cost was $5,960,000 (in 2012 US dollars). The estimated campaign effectiveness ranged from -1.1% (the SH group) to 1.42% (the W group), leading to an increased disparity in influenza vaccination among non-Hispanic white and non-Hispanic African American (W-AA) groups (0.6 percentage points), W-EH groups (0.1 percentage points), and W-SH groups (1.5 percentage points). The estimated ICER was $23.54 (95% confidence interval $14.21-$39.37) per additionally vaccinated Medicare elderly in a probabilistic analysis. Race/ethnicity-specific ICERs were lowest among the EH group ($22.27), followed by the W group ($22.47) and the AA group ($30.55). The nationwide TV campaign was concluded to be reasonably cost-effective compared with a benchmark intervention (with ICER $44.39 per vaccinated individual) of a school-located vaccination program. Break-even analyses estimated the maximum acceptable campaign cost to be $14,870,000, which was comparable to the benchmark ICER.

CONCLUSIONS

The results could justify public expenditures on the implementation of a future nationwide TV campaign, which should include multilingual campaigns, for promoting seasonal influenza vaccination.

Comparison of periodontal conditions among three elderly populations in Japan and Germany

AIM

There is a growing interest in comparing periodontal conditions between countries. This study compared periodontal disease conditions in three elderly populations- one from Japan and two from Germany.

MATERIALS AND METHODS

We compared periodontal data of 70-year-old subjects from the Niigata Study with 65-74-year-old subjects from the Study of Health in Pomerania (SHIP) and from West Germany (DMS III). A total of 489, 399 and 549 dentate subjects were analysed, respectively. Recording protocols were standardized. Linear or logistic models were used to compare Niigata Study with SHIP.

RESULTS

Elderly German subjects in SHIP and DMS III had significantly more severe periodontal conditions and fewer remaining teeth compared to those in Niigata Study, though differences were less pronounced for DMS III. German subjects showed a significantly different pattern of various periodontal risk factors compared to Japanese subjects. Even after adjustment for putative periodontal risk factors, SHIP subjects still presented significantly higher adjusted values for most periodontal parameters compared to Niigata Study subjects (p < 0.05).

CONCLUSIONS

Periodontitis was more prevalent in SHIP compared with Niigata Study, even after comprehensive risk factor adjustment. Only to a very small extent, differences between studies could be explained by the risk factors explored.

Second Morning ACR Could Be the Alternative to First Morning ACR to Assess Albuminuria in Elderly Population

BACKGROUND

Albumin/creatinine ratio (ACR) from a first morning urine is recommended as a early indicator for diabetic nephropathy. However, it is not always feasible to collect the first morning urine for outpatients. We aimed to explore whether ACR from a second morning urine had a good consistency with that from a first morning urine to predict albuminuria in Chinese elderly citizens.

METHOD

One hundred and ninety-one elderly citizens (≧60 years old) from Junliangcheng community, Dongli district, Tianjin, China were included. A first and second morning urine was collected from each participants, successfully and detected the urinary albumin and creatinine of each urine sample. Albumin to creatinine ratio from a first morning urine (ACR1) was compared with that from a second morning urine (ACR2), and the ability of ACR1 and ACR2 to predict albuminuria was assessed.

RESULT

ACR1 and ACR2 were highly correlated (r = 0.901), especially in male and hypertension group (r = 0.938 and 0.904). The slope and intercept were 0.93 and 0.11 after log-transformed. And there was no statistical difference between values of ACR1 and ACR2 (P = 0.271). Overall, 26.2% participants were detected with albuminuria when judged by ACR1 and 28.3% by ACR2. A good concordance of ACR category (normal or albuminuria) was found between ACR1 and ACR2 (Kappa value = 0.815 in overall; in male and hypertension group were 0.900 and 0.850).

CONCLUSION

A second morning urine ACR could be the alternative to a first morning urine ACR for albuminuria detection in elderly population.

Profile of infective endocarditis at a tertiary-care hospital in Japan over a 14-year period: characteristics, outcome and predictors for in-hospital mortality

OBJECTIVES

The aims of this study were to describe the epidemiological features and clinical characteristics of infective endocarditis (IE) at a tertiary-care hospital in Japan and to identify the factors associated with in-hospital mortality.

METHODS

A retrospective observational study was conducted at a 925-bed tertiary-care teaching hospital in Japan. All adult patients diagnosed with definite IE between August 2000 and July 2014 according to the modified Duke criteria were included.

RESULTS

A total of 180 patients (60.6% men; mean age, 69.1 years) with definite IE were included. The most common pathogen was Staphylococcus aureus (27.2%). Nine patients (5.0%) had culture-negative IE. Transthoracic and transoesophageal echocardiography were performed in 180 (100%) and 132 patients (73.3%), respectively, and vegetations were detected in 128 patients (71.1%). Surgical therapy was performed in 31 patients (17.2%). Overall, the in-hospital mortality rate was 26.1%. The independent predictors of in-hospital mortality were methicillin-resistant S. aureus (MRSA), vascular phenomena, health care-associated IE and heart failure.

CONCLUSIONS

MRSA, vascular phenomena, health care-associated IE and heart failure were independent predictors of in-hospital mortality. The unique characteristics in our cohort were the very high mean age, low rate of culture-negative IE, high rate of definite IE without detected vegetations and predominance of S. aureus.

Effects of income supplementation on health of the poor elderly: the case of Mexico

We use an income supplementation experiment we designed in the state of Yucatan in Mexico for residents 70 y and older to evaluate health impacts of additional income. Two cities in the State of Yucatan, Valladolid (treatment) and Motul (control), were selected for the income supplementation experiment. Elderly residents of Valladolid were provided the equivalent of an additional $67 per month, a 44% increase in average household income. We designed a survey given to residents of both cities before and 6 mo after the income supplement about their health and other aspects of overall well-being. Both baseline and follow-up surveys collect self-reported data on health, physical functioning, and biomarkers. Anthropometric measurements for every age-eligible respondent, including height, weight, and waist circumference, were collected. We also collected lung capacity, grip strength, a series of balance tests, and a timed walk. Our results show significant health benefits associated with the additional income. Relative to the control site, there was a statistically significant improvement in lung function and an improvement in memory. These improvements are equivalent to a reduction in age of 5-10 y. Residents used their extra income to go to the doctor, buy their medications, and alleviate their hunger. The fear that this extra income could be undone by reduced transfers from other family members or unwise expenditures by the poor elderly appears to be unfounded.

Effect of aging on human circulatory system in normotensive healthy subjects

Aging is associated with degenerative changes in cardiac and endothelial function (EF). This study was done to assess whether age-related changes take place on EF, carotid intima-media thickness (IMT), blood pressure (BP), and echocardiographic measurements. All volunteers were healthy normotensive healthy subjects. They were divided into three groups. Group 1, young adults: < 40 years old; Group 2, middle age: between 40 and 60 years old; Group 3, elderly: > 60 years old. High-frequency vascular ultrasound was used to assess the baseline brachial artery dimension and flow velocity after reactive hyperemia. The carotid IMT and echocardiographic measurements including Doppler variables were recorded in all subjects. Systolic BP, left ventricular mass, and left ventricular end-diastolic volume increased progressively with age (p < 0.001). Left ventricular ejection fraction decreased progressively with age (male, p = 0.034; female, p = 0.001); E/A ratio of the left ventricular flow spectrum declined with age (p < 0.001). The ultrasonic EF variables of flow increased during reactive hyperemia and IMT increased with age (p < 0.001). Our study demonstrates that BP, body weight, and ultrasonic variables changed significantly with age. The aging-associated changes provide insight into progression to atherosclerosis.

Incidences of unruptured intracranial aneurysms and subarachnoid hemorrhage: results of a statewide study

BACKGROUND

The incidence of unruptured intracranial aneurysms (UIAs) and the current public health impact may be higher than that reported in previous studies owing to an increase in the elderly population in the United States.

OBJECTIVE

To report the current incidences of UIAs and subarachnoid hemorrhages (SAH) by using a population-based methodology.

METHODS

Statewide estimates of patients admitted with UIAs and SAH were obtained from the data obtained by the Minnesota Hospital Association. We calculated the annual incidences per 100,000 persons by using the 2010 census data from the U.S. Census Bureau. For the denominator, total persons in each year were categorized into 10-year intervals.

RESULTS

The incidences of UIAs and SAH were 15.6 and 7.7 per 100,000 persons, respectively. There were higher incidences of both UIAs and SAH among women (22.5 and 9.6 per 100,000 persons, respectively). The highest incidence of UIAs occurred in those aged between 75 and 84 years (61.6 per 100,000 persons). The highest incidence of SAH occurred in those aged 85 years and older (30.1 per 100,000 persons).

CONCLUSION

An increase in both incidences of UIAs and SAH can be expected owing to the continued increase of the elderly population, particularly women.

Depressive symptoms and cardiovascular burden-related mortality among the aged

BACKGROUND

Depressive symptoms have been linked to increased cardiovascular mortality among the elderly. This study was aimed to test the independent and additive predictive value of depressive symptoms and B-type natriuretic peptide (BNP), a marker of direct cardiovascular stress and a strong predictor of mortality, together with traditional cardiovascular risk markers on total and cardiovascular mortalities in a general elderly population.

METHODS

A total of 508 subjects aged 75 or older participated in the study. The prognostic capacity of depressive symptoms and BNP in regard to total and cardiovascular mortalities was assessed with Cox regression analyses. Depressive symptoms were handled as a dichotomous variable based on the Zung self-rated depression scale score with a cut-off point of 40.

RESULTS

The median follow-up time was 84 months with an interquartile range of 36-99 months. Depressive symptoms reflected susceptibility to all-cause (HR 1·60; 95% CI 1·26-2·04) and cardiovascular mortalities (HR 1·81; 95% CI 1·30-2·52) only in univariable analyses. When cardiovascular illnesses and risk markers were taken into account, depressive symptoms lost their significance as an independent predictor of mortality. BNP as a continuous variable was a significant predictor of both all-cause (HR 1·44; 95% CI 1·22-1·69) and cardiovascular mortalities (HR 1·79; 95% CI 1·44-2·22) in fully adjusted models including depressive symptoms as a covariate.

CONCLUSIONS

The prognostic capacity of depressive symptoms is closely linked to cardiovascular morbidity and has no independent power in an elderly general population. BNP remains a strong harbinger of death regardless of depressive symptoms status.

Fibroblast growth factor 23 (FGF23) and early chronic kidney disease in the elderly

BACKGROUND

Better biomarkers of CKD reflecting responses to decreased glomerular filtration rate (GFR) are needed. We determined the value of estimated GFR (eGFR) as a threshold for the increase of plasma cFGF23 (C-terminal) and intact fibroblast growth factor-23 (iFGF23) (intact) concentrations in the course of chronic kidney disease (CKD) and compared this eGFR value with values related to increased serum intact parathyroid hormone (iPTH) or phosphorus concentrations in an elderly population.

METHODS

We measured plasma iFGF23, cFGF23, serum phosphorus, calcium, albumin, creatinine, urea, cystatin C, iPTH and vitamin 25-OH-D3 in 3780 population-based study participants aged ≥ 65 years.

RESULTS

Serum phosphorus concentrations hardly increased until mean eGFR reached 47.3 ± 4.7 mL/min/1.73 m(2) but then increased exponentially. Similarly, both iPTH and iFGF23 increased slightly in early CKD but then increased exponentially when eGFR reached 55.0 ± 4.2 mL/min/1.73 m(2) for iPTH and 51.6 ± 5.7 mL/min/1.73 m(2) for iFGF23. The departure point for exponential increases in cFGF23 preceded those for iPTH and iFGF23 and occurred at a mean eGFR of 57.7 ± 7.8 mL/min/1.73 m(2). The prevalence of increased iFGF23 occurred at a remarkably higher eGFR value than that of cFGF23 across the CKD stages.

CONCLUSIONS

The increase in cFGF23 preceded both the increase in iPTH and iFGF23 as eGFR declined. Increased plasma iFGF23 level did not precede the rise in serum iPTH concentrations and did not occur before stage-3 CKD in elderly persons. However, cFGF23 was not an early marker of CKD in the elderly subjects.

Projections of trends in overweight in the elderly population in Germany until 2030 and international comparison

BACKGROUND/AIMS

To project the numbers of pre-obese (BMI 25-29.99 kg/m²) and obese (BMI > 30 kg/m²) men and women aged 50+ in Germany until 2030 and to compare our estimates with actual figures from four European countries and the USA. Estimates are based on six scenarios encompassing improvements as well as worsenings of current trends.

METHODS

We used pooled data from 1999 to 2009 of the German Microcensus (n = 1,472,547). Using multinomial logistic regression models we estimated age-specific probabilities of pre-obesity and obesity and applied them to the 12th population projection of the Federal Statistical Office.

RESULTS

We project overall increases in absolute numbers of pre-obesity ranging between 14.2 and 18.2 million. However, the prevalence of pre-obesity is likely to decrease slightly. In contrast, absolute and relative numbers of obesity are projected to increase, ranging between 7.2 and 15.8 million. The international comparison revealed that pre-obesity prevalences will remain among the highest in Germany, while obesity is projected to fall below current levels of the UK or the USA.

CONCLUSION

Pre-obesity and, particularly, obesity are likely to become a more prominent health issue in Germany in the near future which could have large repercussions for the public health system.

Multisensory integration mechanisms during aging

The rapid demographical shift occurring in our society implies that understanding of healthy aging and age-related diseases is one of our major future challenges. Sensory impairments have an enormous impact on our lives and are closely linked to cognitive functioning. Due to the inherent complexity of sensory perceptions, we are commonly presented with a complex multisensory stimulation and the brain integrates the information from the individual sensory channels into a unique and holistic percept. The cerebral processes involved are essential for our perception of sensory stimuli and becomes especially important during the perception of emotional content. Despite ongoing deterioration of the individual sensory systems during aging, there is evidence for an increase in, or maintenance of, multisensory integration processing in aging individuals. Within this comprehensive literature review on multisensory integration we aim to highlight basic mechanisms and potential compensatory strategies the human brain utilizes to help maintain multisensory integration capabilities during healthy aging to facilitate a broader understanding of age-related pathological conditions. Further our goal was to identify where further research is needed.

[What is the current use of vitamin K antagonists in the elderly?]

With the recent marketing of the new oral anticoagulants (NOAC), the future of vitamin k antagonist (VKA) needs to be redefined. VKAs are drugs with a narrow therapeutic margin and a high iatrogenic risk that requires a close biological monitoring. Their efficacy has been proven for atrial fibrillation in numerous populations, especially in the elderly. Their side effects and interactions are well known. The measurement of the level of anticoagulation is possible and reliable using the INR (international normalized ratio) and an antidote is usable in case of emergency. The NOAC are at least as effective as VKA with slightly less side-effects especially cerebral hemorrhage, and they do not require biological monitoring. However, data on efficacy and side-effects of NOAC rely mainly on phase III clinical trials that did not particularly target polypathologic and frail populations. In these populations, we therefore have more "real life" information on VKA than NOAC. But studies on NOAC are currently conducted among these populations. A conservative approach would be to maintain VKA to older patients with stable INR. Lastly VKA are the only anticoagulant usable in case of severe renal failure and valvular fibrillation.

Hemiarthroplasty in high risk elderly patient under epidural anesthesia with 0.75% ropivacaine-fentanyl versus 0.5% bupivacaine-fentanyl: Clinical trial

Background:

Anesthetic management of elderly patients is a challenge as aging makes them more susceptible to hemodynamic fluctuations during regional anesthesia. This study was aimed to compare the clinical efficacy of epidural 0.75% ropivacaine fentanyl (RF)– with 0.5% bupivacaine–fentanyl (BF) for hemiarthroplasty in high-risk elderly patients.

Methods:

Sixty elderly consented patients of either sex with American Society of Anesthesiologist ASA II and III, scheduled for elective hemiarthroplasty were randomized into two Groups of 30 patients to receive epidural study solution of 15 mL of 0.75% Ropivacaine or 0.5% Bupivacaine with 1 mL fentanyl (50 μg). The hemodynamic variability with onset and duration of sensory and motor blocks were recorded. The adequacy and quality of surgical anesthesia were assessed. The post-epidural nausea and vomiting, shivering, respiratory parameters, or any other side effects were also recorded.

Results:

There was no difference in the demographic profile between groups. The mean onset time to achieve sensory block to the T₁₀ dermatome was rapid in the Group BF (12.4±6.9 vs. 17.5±3.7 min in Group RF). The mean time to achieve motor block was 17.5±3.4 min in Group BF versus 21.7±7.8 min in Group RF. The intraoperative hemodynamic fluctuations showed statistically significant differences between groups. The pruritis was observed in five patients but post-epidural shivering, nausea, vomiting, respiratory depression, or urinary retention were not observed in any patient.

Conclusion:

Epidural 0.75% Ropivacaine with fentanyl showed better clinical profile as compared to 0.5% Bupivacaine with fentanyl for hemiarthroplasty in elderly patients.

Physical activity ameliorates cardiovascular health in elderly subjects: the functional role of the β adrenergic system

Aging is a complex process characterized by a gradual decline in organ functional reserves, which eventually reduces the ability to maintain homeostasis. An exquisite feature of elderly subjects, which constitute a growing proportion of the world population, is the high prevalence of cardiovascular disorders, which negatively affect both the quality of life and the life expectancy. It is widely acknowledged that physical activity represents one of the foremost interventions capable in reducing the health burden of cardiovascular disease. Interestingly, the benefits of moderate-intensity physical activity have been established both in young and elderly subjects. Herein we provide a systematic and updated appraisal of the literature exploring the pathophysiological mechanisms evoked by physical activity in the elderly, focusing on the functional role of the β adrenergic system.

The clustering of cardiovascular disease risk factors and their impacts on annual medical expenditure in Japan: community-based cost analysis using Gamma regression models

OBJECTIVE

The clustering of cardiovascular disease (CVD) risk factors is a serious threat for increasing medical expenses. The age-specific proportion and distribution of medical expenditure attributable to CVD risk factors, especially focused on the elderly, is thus indispensable for formulating public health policy given the extent of the ageing population in developed countries.

DESIGN

Cost analysis using individuals' medical expenses and their corresponding health examination measures.

SETTING

Shiga prefecture, Japan, from April 2000 to March 2006.

PARTICIPANTS

33 213 participants aged 40 years and over.

MAIN OUTCOME MEASURES

Mean medical expenditure per year.

METHODS

Gamma regression models were applied to examine how the number of CVD risk factors affects mean medical expenditure. The four CVD risk factors analysed in this study were defined as follows: hypertension (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg), hypercholesterolaemia (serum total cholesterol ≥240 mg/dl), high blood glucose (casual blood glucose ≥200 mg/dl) and smoking (current smoker). Sex-specific and age-specific investigations were carried out on the elderly (aged 65 and over) and non-elderly (aged 40-64) populations.

RESULTS

The mean medical expenditure (per year) for the no CVD risk-factor group was only 110 000 yen at age 50 (men, 110 708 yen; women, 107 109 yen), but this expenditure was 6-7 times higher for 80-year-olds who have three or four CVD risk factors (men, 603 351 yen; women, 765 673 yen). The total overspend (excess fraction) was larger for the non-elderly (men, 15.4%; women, 11.1%) than that for the elderly (men, 0.1%; women, 5.2%) and largely driven by people with one or two CVD risk factors, except for elderly men.

CONCLUSIONS

The age-specific proportion and distribution of medical expenditure attributable to CVD risk factors showed that a high-risk approach for the elderly and a population approach for the majority are both necessary to reduce total medical expenditure in Japan.

[Size and type of frequent use of ambulatory medical care among the elderly population in Germany: a study based on statutory health insurance data]

BACKGROUND

The authors report the results of a study on frequent attenders in ambulatory medical care among elderly people in Germany and on the factors related to frequent attendance such as age, sex, multi-morbidity and long-term care dependency.

METHODS

The study was based on claims data of all policy holders aged 65 and over of a statutory health insurance company operating nationwide in Germany in 2004 (n=123,224). Utilisation was analysed by the number of contacts with practices of physicians working in the ambulatory medical care sector and by the number of different practices contacted. The criteria for frequent attendance included greater than or equal to 50 contacts and/or greater than or equal to 10 different practices contacted and/or greater than or equal to 3 practices of the same discipline contacted within one year. Descriptive statistical analysis and logistic regression were used.

RESULTS

19% of the elderly were identified as frequent attenders, which corresponds to some 3.5 million people in Germany. Two main types of frequent attendance were identified: one is characterised by very many contacts, old age, frequent presence of multi-morbidity, and/or long-term care dependency. The other type is the younger, less frequently multi-morbid attender who is considerably less often dependent on long-term care, and characterised by large numbers of contacted practices and/or practices of the same discipline.

CONCLUSION

Frequent attendance is due to several factors. The problem of frequent attendance needs further research that is not exclusively based on claims data. We found a high rate of frequent attendance. Further research should clarify if this is to the benefit of elderly people.

Anemia associated with chronic heart failure: current concepts

Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.

Clinical presentation and outcome of perioperative myocardial infarction in the very elderly following hip fracture surgery

BACKGROUND

Patterns of clinical symptoms and outcomes of perioperative myocardial infarction (PMI) in elderly patients after hip fracture repair surgery are not well defined.

METHODS

A retrospective 1:2 case-control study in a cohort of 1212 elderly patients undergoing hip fracture surgery from 1988 to 2002 in Olmsted County, Minnesota.

RESULTS

The mean age was 85.3 ± 7.4 years; 76% female. PMI occurred in 167 (13.8%) patients within 7 days, of which 153 (92%) occurred in first 48 hours; 75% of patients were asymptomatic. Among patients with PMI, in-hospital mortality was 14.4%, 30-day mortality was 29 (17.4%), and 1-year mortality was 66 (39.5%). PMI was associated with a higher inpatient mortality rate (odds ratio [OR], 15.1; confidence interval [CI], 4.6-48.8), 30-day mortality (hazard ratio [HR], 4.3; CI, 2.1-8.9), and 1-year mortality (HR, 1.9; CI, 1.4-2.7).

CONCLUSION

Elderly patients, after hip fracture surgery, have a higher incidence of PMI and mortality than what guidelines indicate. The majority of elderly patients with PMI did not experience ischemic symptoms and required cardiac biomarkers for diagnosis. The results of our study support the measurement of troponin in postoperative elderly patients for the diagnosis of PMI, in order to implement in-hospital preventive strategies to reduce PMI-associated mortality.

Effects of bispectral index monitoring on isoflurane consumption and recovery profiles for anesthesia in an elderly asian population

Background:

Age related limited physiological reserves and associated co-morbidities in elderly patients require careful titration of inhalational anesthetic agents to minimize their side effects. The use of Bispectral index (BIS) monitoring may be helpful in this regard. The objectives of this study were to evaluate the effect of BIS monitoring on Isoflurane consumption during maintenance and recovery profile at the end of anesthesia. This Quasi experimental study was conducted for a 1 year period at the main operating units of a tertiary care hospital.

Materials and Methods:

Total 60 patients of age 60 years and above were enrolled in either standard practice (SP) or (BIS) group. In the SP group, the anesthesia depth was maintained as a routine clinical practice, while in BIS group it was maintained by monitoring the BIS score between 45 and 55. Standard anesthesia care was provided to all of the patients. Data including demographics, isoflurane consumption, hemodynamic variables and recovery profiles were recorded in both groups.

Results:

The mean isoflurane consumption was lower (P = 0.001) in the BIS group. The time to eye opening, extubation and ready to shift was shorter (P = 0.0001) in BIS group. The patients in BIS group had higher Post anesthesia recovery score (P = 0.0001) than the SP group.

Conclusion:

The use of BIS in an elderly Asian population resulted in 40% reduction of isoflurane usage. The patients having BIS monitoring awoke earlier and had better recovery profiles at the end of anesthesia.

What is the prevalence of musculoskeletal problems in the elderly population in developed countries? A systematic critical literature review

BACKGROUND

The proportion of older people will be tripled by the year 2050. In addition, the incidence of chronic musculoskeletal (MSK) conditions will also increase among the elderly people. Thus, in order to prepare for future health care demands, the magnitude and impact of MSK conditions from this growing population is needed. The objective of this literature review is to determine the current prevalence of MSK disorders in the elderly population.

METHODS

A systematic literature search was conducted in Pubmed on articles in English, published between January 2000 and July 2011. Studies from developed countries with prevalence estimates on elderly people (60+) on the following MSK conditions were included: Non-specific extremity pain, rheumatoid arthritis, osteoarthritis, osteoporosis, and back pain. The included articles were extracted for information and assessed for risk of bias.

RESULTS

A total of 85 articles were included with 173 different prevalence estimates. Musculoskeletal disorders are common in the elderly population, but due to heterogeneity of the studies, no general estimate on the prevalence of MSK can be determined. Women report more often MSK pain than men. Overall, prevalence estimates either remain fairly constant or increase slightly with increasing age, but with a tendency to decrease in the oldest (80+) people.

CONCLUSIONS

Musculoskeletal disorders remain prevalent in the elderly population. Given the increasing proportion of elderly population in the world population and the burden of MSK diseases among the elderly people, efforts must be made to maintain their functional capacity for as long as possible through optimal primary and secondary health care.

Does back and neck pain become more common as you get older? A systematic literature review

BACKGROUND

It is generally believed that the prevalence of back pain increases with age and as the proportion of elderly will keep rising we may be facing serious public health concerns in the future.

AIM

The aim of this systematic literature review is to establish whether back pain (i.e. neck, mid-back and/or low back pain) becomes increasingly common in the older population, specifically to study 1) whether there is a significant increase in the prevalence of back pain after middle age, and 2) whether there is a significant gradually increasing prevalence of back pain with continued old age.

METHODS

A systematic literature search was conducted in Pubmed on articles in English, published between January 2000 and July 2011. Non-clinical studies from the developed countries with prevalence estimates on elderly people (60+) on any type of self-reported back pain and on different age groups with adequate sample sizes were included in the review. The included articles were extracted for information by two independent reviewers.

RESULTS

A total of 12 articles were included covering the entire spine. Neck pain was studied nine times, low back pain eight times, back pain three times, upper back two times and neck/shoulders once. All studies showed no significant increase of back pain with age, neither when passing from middle age (i.e. 45+ years of age) into the sixties, nor later in life. In contrast, most studies reported a decline for the oldest group.

CONCLUSIONS

Back pain is no more common in the elderly population (>60 years) when compared to the middle age population. Back pain does not increase with increasing age, but seems to decline in the oldest people.

Prevalence of metabolic syndrome components among the elderly using three different definitions: a cohort study in Finland

OBJECTIVE

Limited data are available on the metabolic syndrome (MetS) and its components in elderly people (aged 70 years and over) at population level in Northern Europe. A study was undertaken to investigate the prevalence of MetS and its components in an aging population by using different definitions.

DESIGN, SETTING, AND SUBJECTS

A cross-sectional study of 539 inhabitants from Northern Finland (mean age 71.9 years) was conducted to investigate the prevalence of MetS, by using the definitions of MetS by the National Cholesterol Education Panel (NCEP), the modified NCEP (NCEPm), and the International Diabetes Federation (IDF).

MAIN OUTCOME MEASURES

Prevalence of MetS by the NCEP, NCEP modified, and IDF criteria.

RESULTS

Overall, the prevalence of MetS was 24.7%, 35.2%, and 37.2% in men, by NCEP, modified NCEP, and IDF-definitions, respectively. In women the corresponding figures were 20.9%, 33.1%, and 47.8%. Hypertension was the most common component in both men (91.8%) and women (89.0%) by the IDF criteria. Glucose abnormalities were particularly prevalent in men (53.2% by NCEP and 78.4% by IDF criteria).

CONCLUSIONS

The most common component was hypertension in both genders. Lower waist-circumference cut-off points of the IDF criteria led to a higher prevalence of MetS particularly in women. Prevalence of MetS varied significantly when measured by different definitions. Nearly half of older women met the IDF definition of MetS, which was more than twofold when compared with NCEP. Clinical practitioners should be aware of the limitations when using set criteria of MetS, in contrast to identifying the individual cardiovascular risk factors and the accumulation of these.

The case for an elderly targeted stroke management

Stroke is a leading cause of death and disability worldwide. The elderly, in whom atrial fibrillation (AF) is most prevalent, carry the greatest risk, undergoing more recurrent, deadlier strokes, with bigger deficits, slower recoveries, and more comorbidities. Evidence-based data on advanced age stroke management are scarce. Age-related cerebral changes might undermine the benefit of established stroke treatments. Nevertheless, the elderly should probably also undergo thrombolysis for ischemic stroke: they do not bleed more, and die not because of hemorrhage but of concomitant illnesses. Beyond natural bleeding risks, AF in advanced age has a high embolic potential if not anticoagulated. Standard or lower intensity warfarin anticoagulation prevents embolic stroke in the elderly with a hemorrhage risk even lower than aspirin. In fact, adverse effects seem to occur more often with aspirin. Excess anticoagulation hazards are prevented with lower starting doses, stricter corrections, more frequent International Normalized Ratio monitoring, and longer adjustment intervals. Validated prognostic scores such as CHADS₂ help minimize bleeds. Direct inhibitors have recently shown a benefit similar to warfarin with fewer hemorrhages. Carefully tailoring antithrombotics to this age group is therefore useful. Antihypertensives probably help 80-plus stroke patients as well, but the risk/benefit of lowering blood pressure in secondary stroke prevention at that age is uncertain. Evidence-based data on diabetes management and use of lipid-lowering drugs are still lacking in this age group. In summary, emerging data suggest that stroke management should be specifically targeted to the elderly to better prevent its devastating consequences in the population at the highest risk.
