Effects of early intensive postoperative physiotherapy on limb function after tibial plateau leveling osteotomy in dogs with deficiency of the cranial cruciate ligament

Objective-To determine effects of early intensive postoperative physiotherapy on limb function in dogs after tibial plateau leveling osteotomy (TPLO) for deficiency of the cranial cruciate ligament (CCL). Animals-8 adult dogs with CCL deficiency. Procedure-After TPLO, dogs underwent a physiotherapy program 3 times/wk (physiotherapy group; n = 4) or a walking program (home-exercise group; 4). All dogs were evaluated before surgery, 1 and 10 days after surgery, and 3 and 6 weeks after surgery. Thigh circumference (TC), stifle joint flexion and extension range of motion (ROM), lameness, and weight-bearing scores were recorded. Results-Before surgery, CCL-deficient limbs had significantly reduced TC and reduced flexion and extension ROMs, compared with values for the contralateral control limb. Six weeks after TPLO, the physiotherapy group had significantly larger TC than the home-exercise group, with the difference no longer evident between the affected and nonaffected limbs. Extension and flexion ROMs were significantly greater in the physiotherapy group, compared with values for the home-exercise group, 3 and 6 weeks after surgery. Six weeks after surgery, the difference in flexion and extension ROMs was no longer evident between the affected and nonaffected limbs in the physiotherapy group. Both groups had improvements for lameness and weight-bearing scores over time, but no difference was found between the 2 groups. Conclusions and Clinical Relevance-After TPLO in CCL-deficient dogs, early physiotherapy intervention should be considered as part of the postoperative management to prevent muscle atrophy, build muscle mass and strength, and increase stifle joint flexion and extension ROMs.

Pharmacological treatment and perceived health status during 1-year follow up in patients diagnosed with coronary artery disease, but ineligible for revascularization. Results from the Euro Heart Survey on Coronary Revascularization

Background It has been recognized that a clinically significant portion of patients with coronary artery disease (CAD) continue to experience anginal and other related symptoms that are refractory to the combination of medical therapy and revascularization. The Euro Heart Survey on Revascularization (EHSCR) provided an opportunity to assess pharmacological treatment and outcome in patients with proven CAD who were ineligible for revascularization. Methods We performed a secondary analysis of EHS-CR data. After excluding patients with ST-elevation myocardial infarction and those in whom revascularization was not indicated, 4409 patients remained in the analyses. We selected two groups: (1) patients in whom revascularization was the preferred treatment option (n = 3777, 86%), and (2) patients who were considered ineligible for revascularization (n = 632, 14%). Results Patient ineligible for revascularization had a worse risk profile, more often had a total occlusion (59% vs. 37%, p < 0.001), were treated more often with ACE-inhibitors (65% vs. 55%, p < 0.001) but less likely with aspirin (83% vs. 88%, p < 0.001). Overall, they had higher case-fatality at 1-year (7.0% vs. 3.7%, p < 0.001). Regarding self-perceived health status, measured via the EuroQol 5D (EQ-5D) questionnaire, these same patients reported more problems on all dimensions of the EQ-5D. Furthermore, in the revascularization group we observed an increase between discharge and 1-year follow up (utility score from 0.85 to 1.00) whereas patients ineligible for revascularization did not improve over time (utility score remained 0.80) Conclusion In this large cohort of European patients with CAD, those considered ineligible for revascularization had more co-morbidities and risk factors, and scored worse on self-perceived health status as compared to revascularized patients in the revascularization group. With the exception of ACE-inhibitors and aspirin, there were no major differences regarding drug treatment between the two groups. Given these clinically significant observations, there appears to be a role for nurse-led, multidisciplinary, rehabilitation teams that target clinically vulnerable patients whose symptoms remain refractory to standard medical care.

A review of plasma endothelin-1 levels in CABG patient group

Introduction: Endothelin-1 is a potent vasoconstricting growth peptide. In physiologic conditions basal levels maintain vascular homeostasis, conversely in pathological situations it may be expressed in response to chronic and acute vascular injury. Elevated levels of plasma ET-1 have been identified in sub-populations at risk of ischaemic heart disease (IHD) including smokers, diabetics and hyerlipidaemic subjects and in patients with atherosclerotic disease. This peptide may be chronically expressed, such as in congestive heart failure where it has been used as a prognostic marker of disease severity and also acutely, after cardiac revascularisation surgery, possibly as a result of endothelial injury and ischaemia. Aims: The objectives of this study were to (1) identify basal endothelin-1 concentrations in a young healthy control group with no risk factors for IHD (control group 1); (2) to compare; (1) venous plasma ET-1 levels preoperatively and post-operatively in patients undergoing CABG surgery, (3) to compare pre-operative plasma ET-1 levels from the CABG group with an age and gender matched control group (control group 2) and (4) combine all three groups to assess correlations between plasma ET-1 and the various risk factors for IHD, including smoking, hypertension, hyperlipidemia, diabetes and family history. Methods: Venous specimens were collected in chilled EDTA tubes and samples measured using an ELISA assay (Biomedica), following the standard protocol for human EDTA plasma. Results: Forty CABG patients (5F, 35M, mean age 66 yrs), 15 control group 1 subjects (8F, 7M, mean age 29 yrs) and 30 control group 2 subjects (5F, 25M, mean age 61 yrs) participated in the study. No significant difference was detected in plasma ET-1 levels between the controls (1) and (2), and the CABG group, where plasma ET-1 levels were 3.37+/ 5.19 pmol/L, 1.99+/3.74 pmol/L and 1.28+/1.27 pmol/L, respectively. There was a non-significant elevation in post-op ET-1 plasma in comparison with the pre-op levels (2.50+/0.51 Vs 1.45+/6.44). There were also no statistical correlation between risk factors for IHD including smoking, hypertension, NIDDM, hyperlipidemia or family history when data from both patient and controls groups was merged. Conclusion: Contrary to other findings, plasma ET-1 does not appear to a valid marker for IHD or factors which are strongly associated with the pathogenesis of this disease.

In vitro activities of novel oxapenems, alone and in combination with ceftazidime, against gram-positive and gram-negative organisms

Four novel oxapenem compounds (i.e., AM-112, AM-113, AM-114, and AM-115) were investigated for their β-lactamase inhibitory activity against a panel of isolated class A, C, and D enzymes, which included expanded-spectrum β-lactamase enzymes (ESBLs). The oxapenems were potent β-lactamase inhibitors. Activity varied within the group, with AM-113 and AM-114 proving to be the most active compounds. The 50% inhibitory concentrations for these agents were up to 100,000-fold lower than that of clavulanic acid against class C and D enzymes. As a group, the oxapenems were more potent than clavulanic acid against enzymes from all classes. The ability of these compounds to protect ceftazidime from hydrolysis by β-lactamase-producing strains was evaluated by MIC tests that combined ceftazidime and each oxapenem in a 1:1 or 2:1 ratio. The oxapenems markedly reduced the MICs for ceftazidime against class C hyperproducing strains and strains producing TEM- and SHV-derived ESBLs. There was little difference between the activity of 1:1 and 2:1 combinations of ceftazidime and oxapenem. The oxapenems failed to enhance the activity of ceftazidime against derepressed AmpC-producing Pseudomonas aeruginosa strains.

Quality of life, stress and mental health in parents of children with parentally diagnosed food allergy compared to medically diagnosed and healthy controls

Background. Food allergy is related to poorer quality of life (QoL) and mental health of caregivers. Many parents diagnose food allergy in their child without seeking medical care and there is limited research on this group. This study investigated parental QoL and mental health in parents of children with parent-diagnosed food allergy (PA), medically diagnosed food allergy (MA), and a control group with no allergy (NA). Methods. One hundred and fifty parents from a general population completed validated measures of QoL, anxiety, depression, and stress. Results. Parents of children with food allergy (PA or MA) reported higher stress, anxiety, and depression than the control group (all ). Parents of children with MA reported poorer food allergy related QoL compared to parents of children with PA (); parents of children with PA reported poorer general QoL compared to parents of children with MA (). Conclusion. Parents of children with food allergy have significantly poorer mental health compared to healthy controls, irrespective of whether food allergy is medically diagnosed or not. It is important to encourage parents to have their child medically tested for food allergy and to recognise and refer for psychological support where needed.

Profile of anisometropia and aniso-astigmatism in children; prevalence and association with age, ocular biometric measures, and refractive status

Purpose. We describe the profile and associations of anisometropia and aniso-astigmatism in a population-based sample of children. Methods. The Northern Ireland Childhood Errors of Refraction (NICER) study used a stratified random cluster design to recruit a representative sample of children from schools in Northern Ireland. Examinations included cycloplegic (1% cyclopentolate) autorefraction, and measures of axial length, anterior chamber depth, and corneal curvature. ?2 tests were used to assess variations in the prevalence of anisometropia and aniso-astigmatism by age group, with logistic regression used to compare odds of anisometropia and aniso-astigmatism with refractive status (myopia, emmetropia, hyperopia). The Mann-Whitney U test was used to examine interocular differences in ocular biometry. Results. Data from 661 white children aged 12 to 13 years (50.5% male) and 389 white children aged 6 to 7 years (49.6% male) are presented. The prevalence of anisometropia =1 diopters sphere (DS) did not differ statistically significantly between 6- to 7-year-old (8.5%; 95% confidence interval [CI], 3.9–13.1) and 12- to 13-year-old (9.4%; 95% CI, 5.9–12.9) children. The prevalence of aniso-astigmatism =1 diopters cylinder (DC) did not vary statistically significantly between 6- to 7-year-old (7.7%; 95% CI, 4.3–11.2) and 12- to 13-year-old (5.6%; 95% CI, 0.5–8.1) children. Anisometropia and aniso-astigmatism were more common in 12- to 13-year-old children with hyperopia =+2 DS. Anisometropic eyes had greater axial length asymmetry than nonanisometropic eyes. Aniso-astigmatic eyes were more asymmetric in axial length and corneal astigmatism than eyes without aniso-astigmatism. Conclusions. In this population, there is a high prevalence of axial anisometropia and corneal/axial aniso-astigmatism, associated with hyperopia, but whether these relations are causal is unclear. Further work is required to clarify the developmental mechanism behind these associations.

Balance and gait in children with dyslexia

Tests of postural stability have provided some evidence of a link between deficits in gross motor skills and developmental dyslexia. The ordinal-level scales used previously, however, have limited measurement sensitivity, and no studies have investigated motor performance during walking in participants with dyslexia. The purpose of this study was to investigate if continuous-scaled measures of standing balance and gait could discriminate between groups of impaired and normal readers when investigators were blind to group membership during testing. Children with dyslexia (n=22) and controls (n=18), aged 10-12 years, performed walking tests at four different speeds (slow-preferred-fast-very fast) on an even and an uneven surface, and tests of unperturbed and perturbed body sway during standing. Body movements were registered by a triaxial accelerometer over the lower trunk, and measures of reaction time, body sway, walking speed, step length and cadence were calculated. Results were controlled for gender differences. Tests of standing balance with eyes closed did not discriminate between groups. All unperturbed standing tests with eyes open showed significant group differences (P<0.05) and classified correctly 70-77.5% of the subjects into their respective groups. Mean walking speed during very fast walking on both flat and uneven surface was ≥0.2 m/s (P≤0.01) faster for controls than for the group with dyslexia. This test classified 77.5% and 85% of the subjects correctly on flat and uneven surface, respectively Cadence at preferred or very fast speed did not differ statistically between groups, but revealed significant group differences when all subjects were compared at a normalised walking speed (P≤0.04). Very fast walking speed as well as cadence at a normalised speed discriminated better between groups when subjects were walking on an uneven surface compared to a flat floor. Continuous-scaled walking tests performed in field settings may be suitable for motor skill assessment as a component of a screening tool for developmental dyslexia.

Anticholinergic burden in older adults with intellectual disability; relationships with multimorbidity and adverse effects

Background: Anticholinergic medications may be associated with adverse clinical outcomes, including acute impairments in cognition and anticholinergic side effects, the risk of adverse outcomes increasing with increasing anticholinergic exposure. Older people with intellectual disability may be at increased risk of exposure to anticholinergic medicines due to their higher prevalence of comorbidities. We sought to determine anticholinergic burden in ageing people with intellectual disability. Methods: Medication data (self-report/proxy-report) was drawn from Wave 1 of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA), a study on the ageing of 753nationally representative people with an IDC40 years randomly selected from the National Intellectual Disability Database. Each individual’s cumulative exposure to anticholinergic medications was calculated using the Anticholinergic Cognitive Burden Scale (ACB) amended by a multi-disciplinary group with independent advice to account for the range of medicines in use in this population. Results: Overall, 70.1 % (527) reported taking medications with possible or definite anticholinergic properties (ACBC1), with a mean (±SD) ACB score of 4.5 (±3.0) (maximum 16). Of those reporting anticholinergic exposure (n=527), 41.3 % (217) reported an ACB score o fC5. Antipsychotics accounted for 36.4 % of the total cumulative ACB score followed by anticholinergics (16 %) and antidepressants (10.8 %). The most frequently reported medicine with anticholinergic activity was carbamazepine 16.8 % (127). The most frequently reported medicine with high anticholinergic activity (ACB 3) was olanzapine13.4 % (101). There was a significant association between higher anti-cholinergic exposure and multimorbidity, particularly mental health morbidity, and some anticholinergic adverse effects such as constipation and day-time drowsiness but not self-rated health. Conclusion: Using simple cumulative measures proved an effective means to capture total burden and helped establish that anticholinergic exposure in the study population was high. The finding highlights the need for comprehensive reviews of medications.

Inadequacy of Micronutrients, Fat, and Fiber Consumption in the Diets of Haitian-, African- and Cuban-Americans with and without Type 2 Diabetes

Micronutrient insufficiency, low dietary fiber, and high saturated fat intake have been associated with chronic diseases. Micronutrient insufficiencies may exacerbate poor health outcomes for persons with type 2 diabetes and minority status. We examined dietary intakes using the Recommended Dietary Allowances (RDAs) of micronutrients, and Adequate Intakes (AIs) of fiber, and Dietary Guidelines for Americans (DGA) for saturated fat in Haitian-, African-, and Cuban- Americans (n = 868), approximately half of each group with type 2 diabetes. Insufficient intakes of vitamins D and E and calcium were found in over 40 % of the participants. Over 50 % of African- and Cuban- Americans consumed over 10 % of calories from saturated fat. Haitian-Americans were more likely to have insufficiencies in iron, B-vitamins, and vitamins D and E, and less likely to have inadequate intake of saturated fat as compared to Cuban-Americans. Vitamin D insufficiency was more likely for Haitian-Americans as compared to African- Americans. Diabetes status alone did not predict micronutrient insufficiencies; however, Haitian-Americans with no diabetes were more likely to be insufficient in calcium. Adjusting for age, gender, energy, smoking, physical activity, access to health care, and education negated the majority of micronutrient insufficiency differences by ethnicity. These findings suggest that policies are needed to ensure that low-cost, quality produce can be accessed regardless of neighborhood and socioeconomic status.

Investigating relative clauses in children with specific language impairment

Background: It is well documented that children with Specific Language Impairment (SLI) experience significant grammatical deficits. While much of the focus in the past has been on their morphosyntactic difficulties, less is known about their acquisition of complex syntactic structures such as relative clauses. The role of memory in language performance has also become increasingly prominent in the literature. Aims: This study aims to investigate the control of an important complex syntactic structure, the relative clause, by school age children with SLI in Ireland, using a newly devised sentence recall task. It also aims to explore the role of verbal and short-termworking memory in the performance of children with SLI on the sentence recall task, using a standardized battery of tests based on Baddeley’s model of working memory. Methods and Procedures: Thirty two children with SLI, thirty two age matched typically developing children (AM-TD) between the ages of 6 and 7,11 years and twenty younger typically developing (YTD) children between 4,7 and 5 years, completed the task. The sentence recall (SR) task included 52 complex sentences and 17 fillers. It included relative clauses that are used in natural discourse and that reflect a developmental hierarchy. The relative clauses were also controlled for length and varied in syntactic complexity, representing the full range of syntactic roles. There were seven different relative clause types attached to either the predicate nominal of a copular clause (Pn), or to the direct object of a transitive clause (Do). Responses were recorded, transcribed and entered into a database for analysis. TheWorkingMemory Test Battery for children (WMTB-C—Pickering & Gathercole, 2001) was administered in order to explore the role of short-term memory and working memory on the children’s performance on the SR task. Outcomes and Results: The children with SLI showed significantly greater difficulty than the AM-TD group and the YTD group. With the exception of the genitive subject clauses, the children with SLI scored significantly higher on all sentences containing a Pn main clause than those containing a transitive main clause. Analysis of error types revealed the frequent production of a different type of relative clause than that presented in the task—with a strong word order preference in the NVN direction indicated for the children with SLI. The SR performance for the children with SLI was most highly correlated with expressive language skills and digit recall. Conclusions and Implications: Children with SLI have significantly greater difficulty with relative clauses than YTD children who are on average two years younger—relative clauses are a delay within a delay. Unlike the YTD children they show a tendency to simplify relative clauses in the noun verb noun (NVN) direction. They show a developmental hierarchy in their production of relative clause constructions and are highly influenced by the frequency distribution of the relative clauses in the ambient language.

Visual memory errors in Parkinson's disease patient with visual hallucinations

The occurrences of visual hallucinations seem to be more prevalent in low light and hallucinators tend to be more prone to false positive type errors in memory tasks. Here we investigated whether the richness of stimuli does indeed affect recognition differently in hallucinating and nonhallucinating participants, and if so whether this difference extends to identifying spatial context. We compared 36 Parkinson's disease (PD) patients with visual hallucinations, 32 Parkinson's patients without hallucinations, and 36 age-matched controls, on a visual memory task where color and black and white pictures were presented at different locations. Participants had to recognize the pictures among distracters along with the location of the stimulus. Findings revealed clear differences in performance between the groups. Both PD groups had impaired recognition compared to the controls, but those with hallucinations were significantly more impaired on black and white than on color stimuli. In addition, the group with hallucinations was significantly impaired compared to the other two groups on spatial memory. We suggest that not only do PD patients have poorer recognition of pictorial stimuli than controls, those who present with visual hallucinations appear to be more heavily reliant on bottom up sensory input and impaired on spatial ability.

The experimentally pathogenesis of Aeromonas hydrophila in Astacus leptodactylus with emphasis on temperature in bacterial pathogenesis

In this study, four hundred freshwater Crayfish (A. leptodactylus) with average weight of 25-40g were purchased from Aras dam reservoirs in west Azerbayjan province and transported to Iranian Artemia Research Center of Uromya province in September 2010. (One hundred crayfish extra purchased for probably mortality). Before implement of experiment the Crayfish were acclimated for ten days. These experiments was designed in four group treatments (Number, 1,2,3,4) and one control group (Number 5) in triplicate with 20 Crayfish in each repetition prepared of glass aquarium with size (50x40x30cm). Many of infected Crayfish were used for isolation of bacteria. Haemolymph sample had been gathered from infected Crayfish with cutting their antennules and transferred to TSA medium (tryptic soy agar) and then A. hydrophila were determined in order to biochemical test. The treatments and repetitions has exposed to A. hydrophila. The concentrations of the bacteria in 4 treatments were respectively 3 x 108 (T=10-15°C), 3x106 (T=25°C), 3 x 106 and 3 x 104 Cfu mL-1 (T=10- i5oc) (4, 2, 3 and 1) that were prepared in individual containers for exposure of treatments. The control (5) prepared without any bacteria and disinfected by oxytetracycline antibiotic with concentration 100 ppm for 24 hours. The hemolymph samples were withdrawn from abdominal second segments of Crayfish for measuring of THC and TPC in interval hours (2, 6, 12, 24, 48, 96, 144, 240 and 336). For histopatological studies the crayfish samples fixed in Davidson fixative. The results indicated that interval 2 hours after experiment the difference of THC value between treatment 4 with control and treatments 1,2, and 3 was significant (P< 0.05). After 48 hours of experiment the difference of THC value between control group with treatment 1 ,2 and 3 was significant (P< 0.05). The interval 336 hours after experiment also the difference of THC value between treatment 2 with treatments 1, 3 and 4 was significant (P< 0.05). The finding of TPP value showed that the last time after challenge (336 h) there was significant difference between treatment 2 with treatment 4 and control group (P< 0.05). In histopathology studying, in hepatopancreas observed hemocyte aggregated and necrosis withof peknosis nucleus that with increased concentration of bacteria and temperature, The value of hemocyte has increased. Gill revealed necrosis and cell death especially with increased concentration of bacteria and temperature. In lower concentration of bacteria in heart no difference observed, but with increased concentration of bacteria (3 x 108) the low aggregation of hemocyte observed in heart. In treatment 3 x 106 with high temperature also distributed of high hemocyte in heart was observed. In digestive system didn't appear any difference in treatments land 3 but in concentration of 3 x 108 Cfu m1-1 and 3 x 106 (T=25°C) in digestive system was revealed the low aggregation of hemocyte.

Association of the TNF-alpha -308 G/A polymorphisms with metabolic responses secondary to a high protein/low carbohydrate versus a standard hypocaloric diet

Background: Mutation analysis has identified a G-> A transition in the promoter region of TNF-alpha gene at position -308 (rs1800629). Objective: The aim of our study was to investigate the influence of polymorphism in -308 GA promoter variant of the TNF alpha gene on metabolic response and weight loss secondary to two hypocaloric diets. Method: A sample of 283 obese subjects was enrolled in a consecutive prospective way. In the basal visit, patients were randomly allocated during 9 months to diet HP (high protein/low carbohydrate hypocaloric diet) and diet S (standard hypocaloric diet). Results: There were no significant differences between the positive effects on weight loss in either genotype group with both diets. With both diets and only in wild genotype (diet HP vs. diet S), total cholesterol (-9.1 ± 3.4 mg/dL vs. -6.9 ± 2.0 mg/dL; p > 0.05), LDL cholesterol (-9.0 ± 2.9 mg/dL vs. -6.5 ± 2.1 mg/dL; p > 0.05) and triglycerides (-23.1 ± 5.1 mg/dL vs. -12.3 ± 4.8 mg/dL; p < 0.05) decreased. The improvement in triglycerides was higher in subjects without A allele. With diet HP and only in wild genotype, insulin levels (-3.1 ± 1.8 UI/L; p < 0.05) and HOMA-R (-0.8 ± 0.1 units; p < 0.05) decreased. Conclusion: Carriers of -308 GG promoter variant of TNF-alpha gene have a better metabolic response than -308 GA obese with a high protein hypocaloric diet.

Gender differences in right ventricular function in patients with non-ischaemic cardiomyopathy

The aim of this study is to evaluate sex-related differences in right ventricular (RV) function, assessed with cardiac magnetic resonance imaging, in patients with stable non-ischaemic dilated cardiomyopathy. Mean age was 60.9 ± 12.2 years. Men presented higher levels of haemoglobin and white blood cell counts than women, and performed better in cardiopulmonary stress testing. A total of 24 patients (12 women) presented severe left ventricular (LV) systolic dysfunction, 32 (13 female) moderate and 15 (8 women) mild LV systolic dysfunction. In the group with severe LV systolic dysfunction, average right ventricular ejection fraction (RVEF) was normal in women (52 ± 4 %), whereas it was reduced in men (39 ± 3 %) p = 0.035. Only one woman (8 %) had severe RV systolic dysfunction (RVEF < 35 %) compared with 6 men (50 %) p < 0.001. In patients with moderate and mild LV dysfunction , the mean RVEF was normal in both men and women. In the 14 healthy volunteers, the lowest value of RVEF was 48 % and mean RVEF was normal in women (56 ± 2 %) and in men (51 ±  1 %), p = 0.08. In patients with dilated cardiomyopathy, RV systolic dysfunction is found mainly in male patients with severe LV systolic dysfunction.

Cluster Analysis To Identify Elderly People's Profiles: A Healthcare Strategy Based On Frailty Characteristics.

The new social panorama resulting from aging of the Brazilian population is leading to significant transformations within healthcare. Through the cluster analysis strategy, it was sought to describe the specific care demands of the elderly population, using frailty components. Cross-sectional study based on reviewing medical records, conducted in the geriatric outpatient clinic, Hospital de Clínicas, Universidade Estadual de Campinas (Unicamp). Ninety-eight elderly users of this clinic were evaluated using cluster analysis and instruments for assessing their overall geriatric status and frailty characteristics. The variables that most strongly influenced the formation of clusters were age, functional capacities, cognitive capacity, presence of comorbidities and number of medications used. Three main groups of elderly people could be identified: one with good cognitive and functional performance but with high prevalence of comorbidities (mean age 77.9 years, cognitive impairment in 28.6% and mean of 7.4 comorbidities); a second with more advanced age, greater cognitive impairment and greater dependence (mean age 88.5 years old, cognitive impairment in 84.6% and mean of 7.1 comorbidities); and a third younger group with poor cognitive performance and greater number of comorbidities but functionally independent (mean age 78.5 years old, cognitive impairment in 89.6% and mean of 7.4 comorbidities). These data characterize the profile of this population and can be used as the basis for developing efficient strategies aimed at diminishing functional dependence, poor self-rated health and impaired quality of life.
