Differences between race and sex in measures of hip morphology: a population-based comparative study.

OBJECTIVE: This paper aims to (i) identify differences in measures of hip morphology between four racial groups using anteroposterior (AP) hip x-rays, and (ii) examine whether these differences vary by sex. METHODS: 912 hip x-rays (456 individuals) from four racial groups (European Caucasians, American Caucasians, African Americans and Chinese) were obtained. Males and females (45-75 years) with no radiographic hip OA (Kellgren and Lawrence < Grade 2 or Croft < Grade 1) were included. Eleven features of hip joint morphology were analysed. Linear regression with generalised estimating equations (GEE) was used to determine race and sex differences in hip morphology. Post-hoc Bonferroni procedure was used to adjust for multiple comparisons. RESULTS: The final analysis included 875 hips. Chinese hips showed significant differences for the majority of measures to other racial groups. Chinese were characterised by more shallow and narrow acetabular sockets, reduced femoral head coverage, smaller femoral head diameter, and a lesser angle of alignment between the femoral neck and shaft. Variation was found between other racial groups, but with few statistically significant differences. The average of lateral centre edge angle, minimum neck width and neck length differed between race and sex (p-value for interaction < 0.05). CONCLUSIONS: Significant differences were found in measures of morphology between Chinese hips compared to African Americans or Caucasian groups; these may explain variation in hip OA prevalence rates between these groups and the lower rate of hip OA in Chinese. Sex differences were also identified, which may further explain male-female prevalence differences for OA.

Tooth avulsion accidents due to urgent and emergency orotracheal intubation.

BACKGROUND: Intubation is necessary during critical situations to reduce the risk of death. In Brazil, a need exists to determine the prevalence of tooth avulsions in emergency and urgent care. The objective of this study was to identify the causes of orotracheal intubation (OTI), the number of tooth avulsions, and the avulsed teeth that result from urgent and emergency intubation. MATERIAL AND METHODS: The sample consisted of 116 patients (total group) in intensive care units (ICUs) distributed across Group 1 (G1), which was composed of 71 patients from an urgent-care hospital, and Group 2 (G2), which was composed of 45 patients from an emergency hospital. Clinical examinations showed dental alveolus with signs of recent exodontia in the upper and lower anterior regions. Sociodemographic data and the reason for intubation were evaluated. The Shapiro-Wilk normality test, chi-square test, Fisher's exact test, Mann-Whitney U test, and univariate logistic regression were performed with a significance level of 5%. RESULTS: The avulsion prevalence was 4.3%, with more cases receiving emergency intubation (n=4). All avulsions occurred in adults, and a significant difference (p=0.011) was observed with regard to the elderly. A 1-year reduction in age increased the chance of tooth avulsion during intubation by 1.09 times; being female increased the chance by 2.88 times. CONCLUSION: Pulmonary problems were the major causes of intubation, with the highest tooth avulsion prevalence observed during emergency intubation. The avulsed teeth were 11, 12, 13, 22, 32, and 33 across all cases.

Effects of treatments for drooling on caries risk in children and adolescents with cerebral palsy.

BACKGROUND: Neuromuscular impairment makes individuals with cerebral palsy (CP) more prone to drooling. Among the treatment options, there are procedures that interfere with saliva production. It is imperative to evaluate the effect of the different modalities since the reduction in salivary flow rate/production may exacerbate the risk of dental caries. MATERIAL AND METHODS: The aim of this study was to compare the effects of different treatments for drooling on caries risk and salivary parameters in children and adolescents with CP. STUDY DESIGN: A total of 142 children and adolescents with CP, aged 6 to 18 years, were assigned to groups based on the different treatments they had received for drooling: G1-anticholinergic drugs (n = 18), G2-botulinum toxin injection (n = 16), G3-salivary glands surgery (n = 16), G4-no treatment (n = 42), and G5-non-drooling subjects (n = 50). All participants were evaluated on the Simplified Oral Hygiene Index, and for the prevalence of dental caries (decayed, missing, and filled teeth index and white spot lesions). Unstimulated whole saliva was collected, and salivary flow rate and osmolality were measured. Chi-square, ANOVA and Poisson regression were calculated. Prevalence ratios and their respective 95 % confidence intervals were obtained. The significance level was fixed at 5%. RESULTS: No differences were found in the decayed, missing, and filled teeth index (p = 0.128) and Simplified Oral Hygiene Index (p = 0.674) among the different groups. G3 presented significantly higher percentages of WSL (p < 0.001), lower values of salivary flow rate (p < 0.001), and higher values of osmolality (p < 0.001). The white spot lesion prevalence ratio was higher only for G3 (Prevalence ratio = 14.36; IC 95% = 4.64-44.40; p < 0.001). CONCLUSIONS: Children and adolescents with CP who had received surgical treatment for drooling exhibited higher number of white spot lesions because of the reduced salivary flow rate and higher salivary osmolality.

Harmonising measures of knee and hip osteoarthritis in population-based cohort studies: an international study.

OBJECTIVE: Population-based osteoarthritis (OA) cohorts provide vital data on risk factors and outcomes of OA, however the methods to define OA vary between cohorts. We aimed to provide recommendations for combining knee and hip OA data in extant and future population cohort studies, in order to facilitate informative individual participant level analyses. METHOD: International OA experts met to make recommendations on: 1) defining OA by X-ray and/or pain; 2) compare The National Health and Nutrition Examination Survey (NHANES)-type OA pain questions; 3) the comparability of the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) scale to NHANES-type OA pain questions; 4) the best radiographic scoring method; 5) the usefulness of other OA outcome measures. Key issues were explored using new analyses in two population-based OA cohorts (Multicenter Osteoarthritis Study; MOST and Osteoarthritis Initiative OAI). RESULTS: OA should be defined by both symptoms and radiographs, with symptoms alone as a secondary definition. Kellgren and Lawrence (K/L) grade ≥2 should be used to define radiographic OA (ROA). The variable wording of pain questions can result in varying prevalence between 41.0% and 75.4%, however questions where the time anchor is similar have high sensitivity and specificity (91.2% and 89.9% respectively). A threshold of 3 on a 0-20 scale (95% CI 2.1, 3.9) in the WOMAC pain subscale demonstrated equivalence with the preferred NHANES-type question. CONCLUSION: This research provides recommendations, based on expert agreement, for harmonising and combining OA data in existing and future population-based cohorts.

A controlled study comparing salivary osmolality, caries experience and caries risk in patients with cerebral palsy.

BACKGROUND: Cerebral palsy (CP) is a permanent neurological disorder accompanied by secondary musculoskeletal masticatory disorder, with repercussion on chewing and deglutition functions. In these conditions, the liquids ingestion is compromised resulting in salivary osmolality alteration. The objective of this study was to compare salivary osmolality, caries experience and caries risk between normoreactive individuals and patients with CP. MATERIAL AND METHODS: The participants were 4-20 years old: 52 patients with CP treated at a reference rehabilitation centre (study group, SG), and 52 normoreactive individuals (control group, CG). Saliva was collected for five minutes using cotton rolls. Following centrifugation, salivary osmolality was determined by freezing point depression osmometry. Evaluations included caries experience (DMFT index), and caries risk based on a caries-risk assessment tool (CAT). Descriptive and inferential statistics (Chi square and Student t tests) were used to compare the groups. Receiver operating characteristic (ROC) analyses were performed and the area under the ROC curve (Az) was calculated. The level of significance was set at 5%. RESULTS: The groups were homogeneous for sex (p=0.843) and age (p=0.128). In the SG, spastic type CP was the most prevalent (80.8%), and patients showed significantly higher salivary osmolality values compared with the CG (p<0.001). No significant differences in caries experience (p=0.159) or caries risk (p=0.297) were observed. ROC curve analysis determined a salivary osmolality cutoff point of >74 for the SG and >54 for the CG in the presence of dental caries. A significant correlation was verified between salivary osmolality and the DMFT index for the SG (p≤0.05). CONCLUSIONS: Although patients with CP showed higher salivary osmolality values, higher caries experience and caries risk were not observed compared with normoreactive individuals.

Do foot & ankle assessments assist the explanation of 1 year knee arthroplasty outcomes?

OBJECTIVE: Whilst a number of risk factors for poor patient reported outcome measures (PROMs) following knee arthroplasty (KA) have been identified, unexplained variability still remains. The role of pre-operative foot and ankle status on such outcomes has not been investigated. The aim of this study was therefore to determine the association of clinical foot and ankle assessments with patient reported outcomes 1 year following KA. DESIGN: One hundred and fifteen participants from the Clinical Outcomes in Arthroplasty Study (COASt), underwent detailed foot and ankle assessments at baseline, prior to KA (2012-2014) and were followed up for self-reported outcomes 1 year after surgery. RESULTS: Thirty nine percent of subjects reported foot pain at baseline. Mean pre-operative Oxford Knee Score (OKS; 0 [worst] to 48 [best outcome]) was 21 and post-operative OKS score was 38. In fully adjusted analysis pre-operative foot pain was significantly associated with 1 year outcome (risk ratio [RR] 0.78 95% confidence interval [95% CI] 0.62, 0.98). No significant association was observed between ankle dorsiflexion or foot posture and outcome. CONCLUSIONS: Patients with pre-operative foot pain are more likely to have poorer clinically important outcomes 1 year following KA than patients without foot pain. Static ankle dorsiflexion and foot posture do not further explain post-operative KA outcomes. Consideration should also be given to address pre-operative foot pain when attempting to achieve a good clinical outcome for KA.

Bone density and body composition in newly licenced professional jockeys.

The primary objective is the description of bone mineral density (BMD) and body composition in newly licensed jockeys. One in three male, flat jockeys has a very low bone mineral density. Further research is needed to assess the short-term risk of fractures and long-term health implications of these findings. INTRODUCTION: Describe bone mineral density (BMD) and body composition in entry-level male and female, flat and jump jockeys in Great Britain. METHODS: Data was collected on jockeys applying for a professional jockey license between 2013 and 2015. Areal BMD at the spine, femoral neck (FN), total hip and body composition were assessed by dual-energy X-ray absorptiometry (DXA) scan. We examined differences between BMD and body composition by gender and race type (flat or jump). Volumetric bone mineral apparent density (BMAD) of the spine and FN was also calculated to account for group differences in bone size. RESULTS: Seventy-nine male flat jockeys (age 18.5 ± 1.9, BMI 19.0 ± 1.4), 69 male jump (age 20.7 ± 2.0, BMI 20.6 ± 1.3) and 37 female flat jockeys (age 19.3 ± 2.0, BMI 20.8 ± 1.7) took part in this study. Spine BMD Z-scores ≤-2 for male flat, male jump and female flat jockeys were 29, 13 and 2.7%, respectively. Spine BMD was lower in male than female flat jockeys (p<0.001). All BMD scores were lower in male flat compared to male jump jockeys (p<0.001). Body fat percent (BF %) was lower in male flat jockeys compared to male jump and female flat jockeys (p<0.05). Lean mass index (LMI) was lower in male flat compared to male jump jockeys (p<0.001). CONCLUSIONS: Male flat jockeys had a significantly lower BMD, LMI and BF% compared to jump jockeys and female flat jockeys. Male flat jockeys had lower spine BMD scores than females. Individual bone maturation may influence these findings. Further investigation into the relevance of low BMD and altered body composition on jockey health is required.

Painful knee but not hand osteoarthritis is an independent predictor of mortality over 23†years follow-up of a population-based cohort of middle-aged women.

UNLABELLED: To assess whether joint pain or radiographic osteoarthritis (ROA) of the knee and hand is associated with all-cause and disease-specific mortality in middle-aged women. METHODS: Four subgroups from the prospective community-based Chingford Cohort Study were identified based on presence/absence of pain and ROA at baseline: (Pain-/ROA-; Pain+/ROA-; Pain-/ROA+; Pain+/ROA+). Pain was defined as side-specific pain in the preceding month, while side-specific ROA was defined as Kellgren-Lawrence grade ≥2. All-cause, cardiovascular disease (CVD) and cancer-related mortality over the 23-year follow-up was based on information collected by the Office for National Statistics. Associations between subgroups and all-cause/cause-specific mortality were assessed using Cox regression, adjusting for age, body mass index, typical cardiovascular risk factors, occupation, past physical activity, existing CVD disease, glucose levels and medication use. RESULTS: 821 and 808 women were included for knee and hand analyses, respectively. Compared with the knee Pain-/ROA- group, the Pain+/ROA- group had an increased risk of CVD-specific mortality (HR 2.93 (95% CI 1.47 to 5.85)), while the knee Pain+/ROA+ group had an increased HR of 1.97 (95% CI 1.23 to 3.17) for all-cause and 3.57 (95% CI 1.53 to 8.34) for CVD-specific mortality. We found no association between hand OA and mortality. CONCLUSION: We found a significantly increased risk of all-cause and CVD-specific mortality in women experiencing knee pain with or without ROA but not ROA alone. No relationship was found between hand OA and mortality risk. This suggests that knee pain, more than structural changes of OA is the main driver of excess mortality in patients with OA.

A comparison of radiographic anatomic axis knee alignment measurements and cross-sectional associations with knee osteoarthritis.

OBJECTIVE: Malalignment is associated with knee osteoarthritis (KOA), however, the optimal anatomic axis (AA) knee alignment measurement on a standard limb radiograph (SLR) is unknown. This study compares one-point (1P) and two-point (2P) AA methods using three knee joint centre locations and examines cross-sectional associations with symptomatic radiographic knee osteoarthritis (SRKOA), radiographic knee osteoarthritis (RKOA) and knee pain. METHODS: AA alignment was measured six different ways using the KneeMorf software on 1058 SLRs from 584 women in the Chingford Study. Cross-sectional associations with principal outcome SRKOA combined with greatest reproducibility determined the optimal 1P and 2P AA method. Appropriate varus/neutral/valgus alignment categories were established using logistic regression with generalised estimating equation models fitted with restricted cubic spline function. RESULTS: The tibial plateau centre displayed greatest reproducibility and associations with SRKOA. As mean 1P and 2P values differed by >2°, new alignment categories were generated for 1P: varus <178°, neutral 178-182°, valgus >182° and for 2P methods: varus <180°, neutral 180-185°, valgus >185°. Varus vs neutral alignment was associated with a near 2-fold increase in SRKOA and RKOA, and valgus vs neutral for RKOA using 2P method. Nonsignificant associations were seen for 1P method for SRKOA, RKOA and knee pain. CONCLUSIONS: AA alignment was associated with SRKOA and the tibial plateau centre had the strongest association. Differences in AA alignment when 1P vs 2P methods were compared indicated bespoke alignment categories were necessary. Further replication and validation with mechanical axis alignment comparison is required.

Vitis labrusca leaf extract prevents pentylenetetrazol-induced oxidative damage but not seizures in rats.

Epilepsy is a disorder of the central nervous system characterized by recurrent seizures. It is a very common disease in which approximately 30% of patients do not respond favorably to treatment with anticonvulsants. Oxidative stress is associated with neuronal damage arising from epileptic seizures. The present study investigated the possible anticonvulsant and antioxidant effects of a leaf extract of Vitis labrusca in an animal model of seizures induced by pentylenetetrazole (PTZ). The animals received injections of V. labrusca extract (10, 30 and 100 mg/kg) or vehicle and, 30 minutes later, they received an injection of PTZ, and were then observed for 30 minutes. The latency time and tonic—clonic seizure time were registered. Oxidative damage in lipids and proteins was quantified in the cerebellum, cerebral cortex and hippocampus. It was observed that the leaf extract were capable of reducing lipid peroxidation and protein oxidation caused by PTZ at all doses tested.

Association between anticonvulsant drugs and teeth-grinding in children and adolescents with cerebral palsy.

The relation between teeth-grinding and the use of drugs acting on the central nervous system of cerebral palsy (CP) patients has not yet been described. The aim of this research was to evaluate the presence or absence of teeth-grinding (sleep and/or awake periods) in normal and in CP children and adolescents, as well as the association of teeth-grinding and use of anticonvulsant drugs. The sample consisted of 207 children and adolescents, divided into three groups: G1, individuals with CP who did not take anticonvulsant drugs; G2, individuals with CP administered medications on a regular basis; and CG, normal individuals. Logistic regression analyses were performed to evaluate the association of teeth-grinding with some variables. No significant statistical differences were observed regarding the presence or absence of teeth-grinding when G1 and G2 were compared. However, compared with the CG, a statistically significant difference was determined, with the CG showing fewer children presenting teeth-grinding (P < 0·001). Among those children/adolescents prescribed drug therapy, the barbiturate group showed a greater frequency of teeth-grinding. CP children and adolescents show a greater and significant presence of grinding of the teeth compared with normal individuals. Subjects taking barbiturate drugs showed greater presence of teeth-grinding, than those who were taking medications from the other groups of anticonvulsant drugs.

Nutritional status and prevalence of dysphagia in cerebral palsy: usefulness of the Eating and Drinking Ability Classification System scale and correlation with the degree of motor impairment according to the Gross Motor Function Classification System.

INTRODUCTION AND OBJECTIVES: Digestive disorders are one of the most common comorbidities among children with cerebral palsy (CP). The aim of this study is to examine the nutritional status of patients with CP, the prevalence of dysphagia by degree of motor impairment, and the impact of digestive disorders on quality of life. MATERIAL AND METHODS: We conducted a descriptive, cross-sectional, open-label study of out-patients with CP from a tertiary hospital in the Region of Madrid using a structured interview, classifying dysphagia using the Eating and Drinking Ability Classification System (EDACS). We gathered demographical and anthropometric data, and analysed the correlation between severity of dysphagia and functional status as measured with the Gross Motor Function Classification System (GMFCS). RESULTS: Our sample included 44 patients (65.9% boys), with a mean (standard deviation) age of 9.34 (5) years and a mean BMI of 18.5 (4.9). Forty-three percent presented safety and efficiency limitations (EDACS level > II). Safety and efficiency limitations were associated with more extensive motor involvement (60% had tetraparesis), more varied clinical manifestations (87% had mixed forms) and poorer functional capacity (100% on GMFCS V). The impact on nutritional status increased with higher EDACS and GMFCS scores. CONCLUSIONS: This is the first study into the usefulness of the EDACS scale in a representative sample of Spanish children and adolescents with CP. Our findings underscore the importance of screening for dysphagia in these patients, regardless of the level of motor impairment, and the need for early treatment to prevent the potential consequences: malnutrition (impaired growth, micronutrient deficiencies, osteopaenia, etc.), microaspiration, or recurrent infections that may worsen patients' neurological status.

Salivary parameters in Brazilian individuals with cerebral palsy who drool.

BACKGROUND: Although drooling of saliva is considered abnormal in a child over 4 years of age, it has been estimated to occur in approximately in 10-37% of children with cerebral palsy. AIM: The aim of this study was to evaluate the flow rate, pH and buffering capacity in saliva of Brazilian individuals with cerebral palsy who drool. METHODS: Cross-sectional assessment of saliva from 139 individuals with cerebral palsy (3-16 years old) enrolled in a specialized rehabilitation centre in Sao Paulo, Brazil, divided into two groups, according to the presence (G1) or absence (G2) of drooling and controls (G3): G1 consisted of 63 individuals who drool; G2 consisted of 76 who do not drool; and G3 consisted of 47 individuals with no neurological damage of similar age and sex. Unstimulated whole saliva was collected and salivary flow rate (mL/min), initial pH and buffering capacity, by titration of saliva with a constant amount of 0.01 N HCl, were evaluated. The results from G1, G2 and G3 were compared by one-way anova and the χ(2) -test. RESULTS: A higher percentage of severe drooling (60.3%) was observed compared with moderate (27.0%) and mild (12.7%) in the cerebral palsy individuals who drool and the prevalence of drooling was highest among children and adolescents with spastic quadriplegia. Significant reductions in salivary flow rate, initial pH, buffering capacity of whole saliva in pH range 6.0-6.9 and total buffering capacity occurred in G1 and G2 compared with G3. CONCLUSION: All individuals with cerebral palsy present lower flow rate, pH and buffering capacity of saliva, which increases the risk of oral diseases.

Pressure pain threshold of masticatory muscles in children and adolescents with and without intellectual disability: a pilot study.

PURPOSE: Pain is considered a stressful experience, related to real or possible tissue damage with emotional, sensory, social and cognitive components. The aim of the study was to evaluate and compare, using a digital algometer, the pressure pain threshold of temporal and masseter muscles of children and adolescents with and without intellectual disability. METHODS: A cross-sectional study was conducted. Data regarding gender and age were collected from the caregiver of children and adolescents with and without intellectual disability. The evaluations followed this sequence: pressure pain threshold of the masseter and temporal muscles, evaluation of pain on touch using the visual analog scale and signs and symptoms of Temporomandibular disorder. The χ2 test, the Kolgomorov-Smirnov test, Student t test and Mann-Whitney test were performed. The significance level was set at 5%. RESULTS: Two homogeneous groups by gender (P = 0.258) and age (P = 0.727) were evaluated, of which 25 children and adolescents presented intellectual disability and another 25 did not have intellectual disability. No significant difference was observed between groups on the pressure pain threshold of the masseter and temporal muscles, nor pressure average or exam time (P > 0.05). Regarding Temporomandibular dysfunction, no difference in signs or symptoms frequency was found (P > 0.05). However, the range of maximum mouth opening was smaller in the intellectual disability group (P = 0.006). CONCLUSION: Children and adolescents with intellectual disability and preserved basic functionalities do not present alterations in pain perception when evaluated with computerized pressure algometer and visual analog scale. They present similar threshold of pain to pressure as those reported by normative children and adolescents. These results emphasize the importance to treat these children and adolescents with intellectual disability with respect to their pain threshold.

Dental caries in cerebral palsied individuals and their caregivers' quality of life.

OBJECTIVE: To study the correlation between caries experience in individuals with cerebral palsy (CP) and the quality of life of their primary caregivers. MATERIALS AND METHODS: Sixty-five non-institutionalized individuals, presenting CP, aged 2-21 years old, were evaluated for caries experience. Their respective caregivers aged 20-74 years old answered the Short Form 36 (SF-36) health survey and Independence Measure for Children. Fifty-eight non-disabled individuals (ND group), aged 2-21 years old, and their respective caregivers, aged 25-56 years old, were submitted to the same evaluation process as the CP group. RESULTS: Primary caregivers of CP individuals exhibited significantly lower scores than the ND group in all subscales of the SF-36 health survey questionnaire: physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role and mental health. The CP group presented significantly higher values for the Decayed, Missed and Filled (DMF-T) index than the ND group and a significant negative correlation was obtained between the SF-36 and DMF-T index. CONCLUSION: The results suggest that caregivers of CP individuals exhibited worse quality of life than those of the non-disabled. A negative correlation exists between caries experience of CP individuals and their caregivers' quality of life.

Assessment scale of the oral motor performance of children and adolescents with neurological damages.

Among the conditions that classify individuals as special needs patients are those resulting from neurological sequelae, particularly cerebral palsy (CP), which is a disorder of high prevalence. Innumerable alterations can be found in individuals with CP but the inability to control striated muscles, due to damages suffered by the central nervous system, should be emphasized. Changes in tonus, speed and strength of oral muscles, reduction of mandibular mobility amplitude and difficulty to passively seal the lips are characteristics observed in such individuals. Categorization of the individual's mastication pattern is important in order to establish diagnosis and treatment protocols and prognosis. The aim of this study was to develop an Oral Motor Assessment Scale (OMAS) and evaluate its performance in terms of construct validity and reliability in a cohort of 53 children and individuals with CP. Two dentists examined the same patients on two different occasions. Good interexaminer (kappa > 0.85) and intra-examiner (kappa > 0.90) agreement was obtained for the majority of the OMAS items. This study shows that the OMAS is an accurate and valid method of assessment of oral motor skills in children and adolescents with neurological damages.

Association of metabolic syndrome with knee and hand osteoarthritis: A community-based study of women.

OBJECTIVE: It is unclear whether the association between osteoarthritis (OA) and metabolic syndrome (MetS) varies with the site of the affected joint and the presence of pain. Our aim was to describe the association between MetS and radiographic OA (ROA) affecting the knee or the hand in the presence or absence of concurrent joint pain. METHODS: Cross-sectional data of 952 women, aged 45-65years from the Chingford study, a population-based longitudinal cohort of middle-aged women initiated in 1988-1989 in London (UK), was analysed. MetS was defined using the National Cholesterol Education Program Treatment Panel III criteria. Data was collected on components of MetS: waist circumference, triglycerides, high-density lipoprotein (HDL), blood pressure and blood glucose. The outcome was four knee and hand OA groups: painful ROA, ROA only, pain only and neither ROA nor pain (reference category). Multinomial logistic regression models adjusted for age and body mass index (BMI) were used to evaluate the effect of presence of MetS and its individual components on OA subgroups for knee and hand separately. RESULTS: 952 eligible women, aged 45-65years was analysed. A significant association was observed between the presence and the number of MetS with painful knee ROA when adjusted for age; however, this association disappeared when BMI was included in the model. In contrast, the presence and the number of MetS were associated with painful interphalangeal (IPJ) OA after adjusting for both age and BMI. Four out of the five MetS components, including triglycerides, HDL-c, hypertension and glucose, were associated with painful IPJ OA. CONCLUSIONS: MetS is associated with painful IPJ OA but not with knee OA once BMI is taking into consideration. Further attention to MetS and OA at different sites is needed to understand the metabolic phenotype in OA.

Introducción y objetivos: La enfermedad digestiva es una de las comorbilidades más frecuentes en niños con parálisis cerebral infantil (PCI). Nuestro objetivo es analizar el estado nutricional de los pacientes con PCI, la prevalencia de disfagia según la afectación motriz (GMFCS) y su repercusión en la calidad de vida.Material y métodosEstudio descriptivo transversal y abierto en pacientes con PCI seguidos en un hospital terciario de la Comunidad de Madrid mediante una entrevista estructurada y la clasificación de la disfagia según la escala Eating and Drinking Ability Classification System (EDACS). Recogimos datos demográficos y antropométricos y relacionamos el nivel de disfagia con el nivel funcional según el Gross Motor Function Classification System (GMFCS).ResultadosLa muestra incluyó 44 pacientes (65,9% varones), con una edad media de 9,34 ± 5 años y un IMC de 18,5 ± 4,9. El 43% tenía limitaciones en seguridad y/o eficiencia (EDACS > II). El porcentaje de pacientes afectados fue mayor cuanto más extensa desde el punto de vista topográfico fue la PCI (tetraparesia 60%), más variada la semiología clínica (87% en formas mixtas) y peor el nivel funcional (100% en GMFCS V). La repercusión nutricional aumentó con puntuaciones más altas en EDACS y GMFCS.ConclusionesPresentamos el primer estudio sobre la utilidad de la escala EDACS en una muestra representativa de niños y adolescentes españoles con PCI. Los resultados deben hacernos reflexionar sobre la importancia del cribado de disfagia en estos pacientes, independientemente del grado de afectación motriz y la necesidad de una intervención precoz para evitar sus principales consecuencias: desnutrición (hipocrecimiento, déficit de micronutrientes, osteopenia, etc.), microaspiraciones o infecciones de repetición que empeoran el estado neurológico.

Our findings underscore the importance of screening for dysphagia in these patients, regardless of the level of motor impairment, and the need for early treatment to prevent the potential consequences: malnutrition (impaired growth, micronutrient deficiencies, osteopaenia, etc.), microaspiration, or recurrent infections that may worsen patients’ neurological status.
