Immediate Effect of Simulated High Heels on Pelvic and Spinal Posture in Healthy Young Subjects: A Cross-Sectional Study.

Background Investigations regarding the role of high-heeled shoes in the alteration of the spinopelvic profile attempted to identify a correlation with pain in the lower back. Conclusions from these studies, however, are controversial. In authors knowledge no studies were carried out to investigate the effect of heels on male population, which has been overlooked due to gender-related customs. Research question What is the immediate effect of the height of heels on the sagittal back profile (trunk inclination (TI), pelvic inclination, lordotic lumbar angle (ITL-ILS), kyphotic dorsal angle, lumbar arrow, and cervical arrow) in females and males, not used to wearing high-heeled shoes? Methods One hundred healthy young adult subjects were enrolled. Three were excluded. The remaining 97 subjects (48 female and 49 male) underwent a three-dimensional analysis of the posterior surface of the trunk, using rasterstereography. The spinopelvic profile in the barefoot condition, and with the heel raised by 3 and 7 cm, was recorded. To evaluate the reproducibility of the measure, the neutral evaluation was repeated twice in 23 subjects (13 males, 10 females). Results The change of heel height did not show statistically significant differences for any of the variables used; instead, significant differences were found stratifying the results according to the sex of the subjects tested. Test-retest evaluation in the neutral condition showed no significant differences using the Student's t-test (p > 0.05). Repeatability was excellent and significant for all data used (minimum TI r = 0.85, maximum ITL-ILS r = 0.97). Significance Studying the effect of heels on the spino-pelvic profile also in the male population is crucial for promoting gender-inclusive healthcare, enhancing occupational health practices and developing possible preventive measures. Nevertheless, in the sample of females and males evaluated in this study, the different heights of heel lift did not immediately induce significant changes in pelvis and spine posture. If there is therefore a correlation between low-back pain and the use of heels, it should not reasonably be sought in the immediate change of the spino-pelvic profile caused by raising the heels. However, the variables analyzed differed according to sex.

Discharge diagnosis and comorbidity profile in hospitalized older patients with dementia.

OBJECTIVES: The aim of this study was to investigate the principal discharge diagnosis and related comorbidity in hospitalized older patients affected by dementia. METHODS: Data from 51,838 consecutive computerized discharge records of the St. Anna University Hospital (Ferrara, Italy) were analyzed. Records included only subjects aged ≥60 years. Number of admissions, length of stay in hospital, primary and secondary discharge diagnosis (by ICD-9-CM code), number of procedures, and possible death were evaluated. RESULTS: Demented patients represented 8.6% of the sample (4466 individuals) and were older and more likely to be female patients compared with controls (47,372 individuals); they were characterized by higher number of admissions to hospital, instrumental clinical investigations, secondary diagnoses, and mortality rate. Among the primary diagnoses, a higher prevalence of cerebrovascular disease, pneumonia, and hip fracture was observed in demented patients. Furthermore, pulmonary embolism, renal failure, septicemia, and urinary infections were frequently reported in demented patients, but not in controls. As regards secondary diagnoses, dementia was associated with an increased risk of delirium, muscular atrophy and immobilization, dehydration, cystitis, and pressure ulcers, whereas the risk for other conditions, including cancer, was reduced. CONCLUSIONS: Among older patients, dementia was associated with higher rate of admissions to hospital and mortality. Discharge diagnoses were sensibly different according to the presence of dementia; in particular, a greater load and a different kind of comorbidity were observed in demented patients. On the whole, our data suggest that the adequate management of demented outpatients might help to reduce hospitalization.

Prior antiplatelet drug use and short-term mortality in older patients with acute ischemic stroke (AIS).

Some studies suggest that previous treatment with antiplatelet agents (AA) might reduce ischemic stroke severity and improve outcomes in terms of clinical deficits or mortality. We evaluated the effect of the prior chronic use of AA on short-term (30 days) mortality in a sample of consecutive patients with AIS. Four hundred thirty-nine older patients (>65 years) with "major" AIS (modified Rankin scale ≥ 3) consecutively admitted to the University ward of Internal Medicine or Geriatrics were enrolled. Stroke was classified according to Oxfordshire Community Stroke Project (OCSP). Data recorded included: (1) clinical features; (2) medical history including home therapies, and vascular risk factors; (3) routine clinical chemistry analyzes (verb)/analyses (noun). Short-term (30 days) mortality was 27.6%. One hundred fifteen subjects (26.2%) were taking AA before admission. Compared with subjects not treated, subjects taking AA were characterized by higher prevalence of recurrent stroke (35% vs. 22%). In this group, a trend toward a higher prevalence of congestive heart failure (CHF), smoking, and altered levels of consciousness (ALC) was noted. Stroke type and short-term mortality (33% vs. 26.2%; odds ratio=OR=1.25; 95% confidence interval=CI=0.75-2.10, age and gender adjusted) were not different between the two groups. Adjustment for glucose, CHF, previous stroke, smoking, and ALC did not change mortality risk (OR=0.83; 95%CI=0.40-1.72). We conclude that in older patients hospitalized for "major" AIS, prior use of AA was not associated with any benefit in terms of short-term mortality both in patients with first, as well as in those with recurrent ischemic stroke.

Plasma soluble gp130 levels are increased in older subjects with metabolic syndrome. The role of insulin resistance.

OBJECTIVE: Increased interleukin-6 plasma levels have been reported in metabolic syndrome (MS); nevertheless, it is unclear whether interleukin-6 activity is exerted through direct signalling only or also through the "trans-signalling". This issue is important to clarify since signalling and "trans-signalling" affect different tissues. We investigated the relationship between MS and the interleukin-6 system in an older population. METHODS: Data from 997 older community dwelling individuals (age ≥ 65 years; females: 56.2%) enrolled the InChianti study were analysed. Interleukin-6, soluble interleukin-6 receptor (sIL-6r), and soluble glycoprotein 130 (sgp130) were measured on plasma by ELISA. MS was defined by the NCEP ATP III criteria; 309 individuals (31%) resulted affected by MS. RESULTS: Subjects with MS had higher interleukin-6 and sgp130 levels compared to controls; a trend toward higher levels of sIL-6R was also observed. The risk of having MS was increased in individuals with high sIL-6r or/and sgp130 levels, independent of age, gender, and interleukin-6 levels. Elevated sgp130 levels were associated with higher plasma glucose, HOMA, triglycerides, and with diabetes both in subjects with and without MS. Although the risk of high sgp130 levels was generally associated with MS (O.R.: 1.77, 95%C.I.: 1.39-2.25), this excess of risk was not present in MS phenotypes excluding the criteria "elevated glucose" or "elevated triglycerides". Furthermore, the association between sgp130 and MS disappeared after adjustment for HOMA. CONCLUSIONS: We found that older individuals with MS have increased sgp130 plasma levels compared with controls; nevertheless, our data suggest that this association might be mediated by insulin resistance.

Elevated C-reactive protein levels and metabolic syndrome in the elderly: The role of central obesity data from the InChianti study.

Metabolic syndrome (MS) and "low grade" systemic inflammation (LGSI) are very common findings in the older population. Although MS and LGSI have been associated in adults, it is not known what is the real contribution of MS, and its single components, to LGSI in older persons, due to the potential confounding effect of comorbidity and aging. We investigated the relationship between increased C-reactive protein (CRP) plasma levels, a marker of LGSI, and MS in 1044 older (> or =65 years) community dwelling Italian individuals enrolled the InChianti study. Metabolic syndrome was defined by the NCEP-ATP III-AHA/NHLBI criteria. High sensitivity CRP (hs.CRP) levels were measured by enzyme-linked immunosorbent assay, and defined as high when >3mg/L. The overall prevalence of MS was 31%. The prevalence of high hs.CRP was 54.5% in subjects with, and 41.3% in those without MS (p<0.001). MS was associated with high hs.CRP levels after adjustment for age, gender, and comorbidity (OR: 1.93, 95% CI: 1.46-2.55). Compared to subjects with MS and no LGSI, individuals with MS and LGSI were characterized by higher waist circumference, BMI, and HOMA score. Multivariate logistic regression analysis confirmed the association between waist circumference and high hs.CRP levels in subjects with MS (waist circumference III vs. I tertile OR: 2.60, 95% CI: 1.79-3.77) independent of age, gender, and important confounding variables including comorbidity. Additional analyses, conducted with and without dichotomization of hs.CRP levels, confirmed the central role of waist circumference in the LGSI phenomenon, independent of gender and diagnosis of MS. We conclude that in older individuals, MS is associated with LGSI, but the association is mainly supported by a strong independent correlation between waist circumference and high hs.CRP levels. In the absence of this specific MS component, it seems that the contribution of MS to LGSI would be modest at best.

Benign joint hypermobility syndrome: psychological features and psychopathological symptoms in a sample pain-free at evaluation1.

30 subjects with BJHS (Hypermobile) (M age = 32.3 yr., SD = 10.4) and two control groups, 25 healthy subjects (Healthy) (M age = 33.9 yr., SD = 9.3) and 30 fibromyalgic patients (Fibromyalgic) (M age = 32.2 yr., SD=9.4), were given the Symptom Checklist-90-R, the Illness Behavior Questionnaire, the Female Functional Symptoms Frequency (FFF) and the Male Functional Symptoms Frequency (MFF), derived from the DSM-III-R, evaluating functional somatic disturbances and their intensity, and the Symptom Questionnaire. The mean scores for the Hypermobile group showed significant psychological distress and increased frequency and intensity of somatic symptoms. Scores on Anxiety and Somatic Symptoms, General Hypochondriasis, Disease Conviction, Affective Disturbance, Denial, and Irritability were significantly higher in the Hypermobile than in the Healthy group. Elevated scores were found for the Fibromyalgic group on the Illness Behavior Questionnaire subscales for Psychological vs Somatic Focus, Disease Affirmation, and Discriminating Factors when compared with the Hypermobile group. Considerable emotional symptoms were detected which should not be underestimated by physicians when establishing an integrated biopsychosocial therapy.
