NCSE-coma in older adults: Clinical data, initial EEG, and hospital outcome.

INTRODUCTION: The clinical-EEG profile and prognosis in nonconvulsive status epilepticus (NCSE-coma) - with preceding SE and without preceding SE - have not been fully established yet. OBJECTIVE: To evaluate the initial EEG, clinical characteristics, and hospital outcome of older adults with NCSE-coma. METHODOLOGY: Clinical variables, immediate prognosis, initial EEG data, and scores on the Status Epilepticus Severity Score (STESS) and the SACE score were evaluated according to the type of NCSE-coma (with and without preceding seizure/SE) in 51 older adult patients treated in the emergency department. RESULTS: The mean age of the participants was 72.2 years. In 23 cases, the diagnosis was NCSE-coma with preceding seizure/SE, and in 28 cases the diagnosis was NCSE-coma without preceding seizure/SE. Previous history of seizures/epilepsy occurred in 11 cases (21.5 %), and was more frequent in NCSE-coma with preceding seizure/SE. The most common etiology was acute. Death within 30 days occurred in 21 cases (41.1 %), but there was no difference between types of NCSE-coma. The predominant EEG finding was the presence of epileptiform discharges/rhythmic delta activity showing morphological/spatial/temporal evolution (classified as A2 in the Salzburg Consensus Criteria [SCC]). There was a significant difference in EEG findings according to the type of NCSE-coma. Total SACE scores averaged 0.9 ± 0.8; on the STESS, it was 4.7 ± 0.4. In the SACE score, the highest total score and a more significant occurrence of scores ≥ 3 (indicating a better prognosis) were observed in NCSE-coma with preceding seizure/SE. CONCLUSION: In older adults, the types of NCSE-coma presented different clinical aspects and patterns on initial EEG. The mortality rates were elevated. The most prevalent EEG findings encompass criteria A2 of the SCC. A history of previous seizures/epilepsy and a more favorable prognosis in the SACE score occurred in NCSE-coma with preceding seizure/SE.

Focal nonconvulsive status epilepticus with impaired consciousness in older adults: Prognosis-related variables.

OBJECTIVE: To assess the prognosis-related clinical-EEG characteristics in older adults with focal nonconvulsive status epilepticus with impaired consciousness (focal NCSE). METHODOLOGY: We prospectively assessed clinical variables and EEG data at diagnosis and after an initial pharmacological protocol (within 24 hours) and their relationship with prognosis in older adults with focal NCSE treated at the emergency room. RESULTS: The clinical presentation of focal NCSE in 45 adults (mean age 73.5 ±â€¯9.1 years) was characterized by decreased consciousness and the presence of subtle ictal phenomena in 24 cases. On the initial EEG, there were lateralized periodic discharges (LPDs) and lateralized rhythmic delta activity (RDA) in 25 cases and epileptiform discharges (EDs > 2.5 Hz) in 32 cases. After the drug protocol, 33 (73.3%) cases had effective clinical improvement. Death after 30 days occurred in 10 (22.2%) cases. In simple and multiple logistic regression, it was observed that older adults with a history of epilepsy/seizures have a greater chance of clinical improvement. The occurrence of death was associated with the presence of RDA in the initial EEG and its subsequent disappearance (OR 6.93, 95% CI 1.20-46.01, p = 0.033). Higher mortality was associated with the presence of LPDs in the initial EEG and with the presence of LPDs/EDs > 2.5 Hz in the EEG after treatment. CONCLUSION: The presence of ED > 2.5 Hz in the initial EEG was the most frequent pattern at focal NCSE. Clinical improvement was associated with a history of epilepsy/seizures. Mortality in the focal NCSE was high and was associated with the presence of RDA in the initial EEG and the occurrence of LPDs/ED > 2.5 Hz after treatment.

Risk of suicide and religious or spiritual beliefs in Brazilian adult patients with epilepsy.

In epilepsy, suicidal behavior is higher compared with the general population. OBJECTIVE: To assess the relationship between suicide risk, religiosity or spirituality, and clinical variables in adult patients with epilepsy (PWE). METHODOLOGY: The data from the suicide module of the Mini International Neuropsychiatric Interview (MINI) were related to scores on the Brief Multidimensional Measure of Religiousness/Spirituality (BMMRS-P) and the Hospital Anxiety and Depression Scale (HADS), as well as clinical variables in 96 adults PWE, with a significance level of p < 0.05. RESULTS: The study included 49 patients with temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) and 47 cases of other epilepsies. The presence of suicide risk in the MINI was observed in 43 (44.7%) cases. Suicide risk was associated with an earlier age of epilepsy onset, higher seizure frequency, neurological abnormalities, and higher scores on the HADS-A and HADS-D scales. Suicide risk was low in 33 (76.7%) cases and moderate or high in 10 (23.2%) cases. Higher suicide risk was associated with higher education levels, focal structural epilepsy, use of ≥2 antiseizure medications, neurological abnormalities, anxiety, and dimensions such as daily spiritual experiences, religious or spiritual coping, organizational religiousness, and total score in the BMMRS-P. DISCUSSION: A high number of patients with epilepsy exhibited suicide risk, with epilepsy-related variables, the presence of anxiety, and perceived lower belongingness and social support from religiosity or spirituality anxiety being associated with a higher risk. The social support provided by religiosity/spirituality may be a non-clinical factor associated with suicidal behavior. Suicide in epilepsy is associated with a complex interaction of multidimensional factors.

Seizure-related injuries in adults: A prospective case-controlled study on risk factors, seizure severity and quality of life.

OBJECTIVE: The current study was conducted to understand the occurrence of seizure-related injuries in people with epilepsy. The relationship between injuries and clinical variables, the perception of seizure severity and quality of life (QoL) and the practice of risky activities were also assessed. The characteristics of the injuries from the onset of epilepsy and in the previous year were assessed. METHODOLOGY: This is a prospective study to assess the occurrence of seizures-related injuries of 72 adult patients with epilepsy. Injury-related data were related to clinical variables and scores of the quality of life in epilepsy inventory (QOLIE-31) and the Seizure Severity Questionnaire (SSQ) with p < 0.05. RESULTS: The mean age of the people with epilepsy was 45.8 ± 15.2 years and the mean length of seizure disorder was 24.0 ± 18.7 years. Seizure-related injuries occurred since the onset of epilepsy in 55 (76.4%) cases and in the previous year in 17 (23.6%) cases. Throughout the lifespan, there was a greater occurrence of injuries in younger patients, with younger age at the onset of epilepsy, using various antiseizure medications and with higher SSQ scores (T test; 54.5 ± 27.7 vs 36.1 ± 23.4, p = 0.011). Injuries in the previous year were associated with a high occurrence of previous injuries, lower scores on the QOLIE-31 (56.7 ± 18.6 vs 66.6 ± 16.1; p = 0.048), higher frequency of seizures and the perception of greater severity of seizures. Seizure-related injuries during risky activities occurred in 11 (20%) cases, associated with a longer length of epilepsy disorder (34.9 ± 15.6 years vs 22.1 ± 17.4 years; p = 0.03) and the need for surgical procedures. CONCLUSION: The occurrence of seizure-related injuries suffered throughout the lifespan and recurrent injuries in the previous year were high. Injuries were significantly associated with epilepsy variables, the perception of greater severity of seizures and risky activities. Seizure-related injuries in the previous year have compromised QoL but not in individuals who suffered injuries throughout their lifespan.

Acupuncture, seizure frequency, and quality of life in temporal lobe epilepsy.

OBJECTIVE: To assess seizure frequency and quality of life (QOL) in a group of adults with temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) before and after 10 weeks of systemic acupuncture sessions and compare the results with a group of patients with TLE-HS not undergoing acupuncture. METHODS: The Quality of Life in Epilepsy Inventory (QOLIE-31) and the initial and final seizure frequency of 26 adult patients with TLE-HS who underwent acupuncture sessions for 10 consecutive weeks were assessed. The data were compared to those of 26 patients with TLE-HS not submitted to acupuncture, with p < 0.05. RESULTS: There was a clinically significant effect in reducing the mean number of seizures per month in the follow-up period of patients submitted or not to acupuncture (no intervention group and intervention group, effect size: -0.94 and -1.01, respectively). In the last four weeks of follow-up, there was a significant difference between the no intervention and intervention groups (0.5 [0-2] and 0 [0-4]; p = 0.018). When using minimally important change (MIC) threshold data for the QOLIE-31 between the final and initial scores, with the Cantril Ladder Scale as anchoring, it was observed that, in the intervention group, large clinically significant effects were seen for all dimensions, except for cognitive function, medication effect, and social function, which presented medium effects. In the follow-up, the variation of the QOLIE-31 scores was positive for both groups; however, it was higher in all dimensions in the intervention group, indicating a better QOL. CONCLUSION: There was a reduction in the mean number of seizures per month in all patients during the follow-up period. Acupuncture significantly reduced the number of seizures in the intervention group in the final phase of the study. QOL improvements occurred in all patients, however, more significantly in the intervention group.

Stigma, emotional aspects, and psychological symptoms in individuals with epilepsy.

The relationship between stigma and psychological aspects in adults with epilepsy is poorly studied. The Stigma Scale of Epilepsy (SSE) was related to the Factorial Neuroticism Scale (FNS), Symptoms Assessment Scale-40 (SAS-40), and clinical aspects of 71 individuals with epilepsy, at a significance level of p < 0.05. Clinical and sociodemographic aspects are associated with the presence of psychological symptoms and emotional maladjustment. The occurrence of psychological symptoms in the SAS-40 was associated with uncontrolled seizures, longer illness duration, and perception of greater stigma. There was a relationship between perceived stigma, age, and epilepsy duration. In the linear regression for determining the factors that potentially affected perception of stigma, the symptom dimensions 'somatization' in the SAS-40 (p < 0.001) and the 'psychosocial maladjustment' in the FNS (p = 0.012) were included, and the clinical aspects were excluded. Psychological symptoms were associated with uncontrolled seizures and perceived stigma. Perception of stigma was associated with somatization and psychosocial maladjustment.

Fetal inhibition of inflammation improves disease phenotypes in harlequin ichthyosis.

Harlequin ichthyosis (HI) is a severe skin disease which leads to neonatal death in ∼50% of cases. It is the result of mutations in ABCA12, a protein that transports lipids required to establish the protective skin barrier needed after birth. To better understand the life-threatening newborn HI phenotype, we analysed the developing epidermis for consequences of lipid dysregulation in mouse models. We observed a pro-inflammatory signature which was characterized by chemokine upregulation in embryonic skin which is distinct from that seen in other types of ichthyosis. Inflammation also persisted in grafted HI skin. To examine the contribution of inflammation to disease development, we overexpressed interleukin-37b to globally suppress fetal inflammation, observing considerable improvements in keratinocyte differentiation. These studies highlight inflammation as an unexpected contributor to HI disease development in utero, and suggest that inhibiting inflammation may reduce disease severity.

Ictal EEG: Etiology and Mortality in Older Adults With Nonconvulsive Status Epilepticus.

Clinical-electroencephalogram (EEG), as well as etiological and prognostic data on subtypes of nonconvulsive status epilepticus (NCSE) are yet to be established. Objective: Evaluate the clinical semiology and EEG findings and prognostic data of older adults with NCSE. Methodology: Characterize the clinical-EEG and prognostic data in the subtypes of NCSE in older adults consecutively admitted to the emergency room of the Pontifícia Universidade Católica de Campinas (PUC-Campinas) University Hospital. Results: When evaluating 105 older adults with altered consciousness, it was possible to diagnose NCSE in 50 (47.6%) older adults, with a mean age of 72.8 ± 8.8 years. NCSE-coma occurred in 6 cases, with NCSE-without coma in 44 cases. The etiology was structural in 41(82%) cases, metabolic in 5 cases, and unknown etiology in 4 cases. Twelve cases had a history of epileptic seizures. On the EEG, epileptiform discharges (EDs > 2.5 Hz) were present in 34(68%) cases and rhythmic delta activity /lateralized periodic patterns occurred in 35(70%) cases. There was clinical improvement after the initial pharmacological treatment in 36 cases and, within 30 days, 18 cases died. The better prognosis was associated with a good response to initial pharmacological treatment (n = 14) and with EDs > 2.5 Hz on EEG (Fisher's exact test; 26 vs 8; P = .012). Conclusion: Focal NCSE with impaired consciousness was the most frequent subtype. The most frequent finding on the EEG was the recording of focal/regional seizures. A high number of cases showed initial clinical improvement, but mortality was high. The favorable prognosis was associated with initial clinical improvement and the presence of EDs > 2.5 Hz. There was no relationship between EEG patterns and the etiology and subtypes of NCSE in older adults.

Religious Experience and Clinical-EEG Aspects in Adult People with Epilepsy.

Spirituality and religiosity are complex cognitive phenomena; however, the relationship between spiritual experiences and epilepsy continues to be debated. Methods. Data from the daily spiritual experience scale (DSES) were related to EEG data and clinical variables of 100 adult people with epilepsy (PWEs). DSES scores were compared to 51 normal individuals (control group [CG]), with a significance level of P < .05. Results. The total score in the DSES was 36.1 ± 14 and 37.6 ± 13.2, respectively, in the PWEs and in the CG. In the PWEs, there was a correlation between DSES and age (Pearson's correlation; -0.22; P = .027) and educational level (0.207; P = .039). PWEs with ≥one seizure/month have a lower frequency of daily spiritual experiences than those with better controlled seizures (T-test; 39.2 ± 16.2 vs 31.7 ± 7.6; P = .038). EEG epileptiform activity (EA) in the right hemisphere was associated with a higher frequency of spiritual experiences than those with left-hemisphere EA (29.8 ± 9.0 vs 38.5 ± 17.5; P = .010). Conclusion. Demographic aspects, EA in the right hemisphere, and lower seizure frequency are associated with daily spiritual experiences in epilepsy, suggesting an association between aspects of spirituality, epilepsy, and neurobiological correlates.

Family support in adults with epilepsy.

BACKGROUND: The perception of family support in chronic disease can be relevant. OBJECTIVE: To assess the perception of family support in adult patients with epilepsy (PWEs) and relate it to quality of life (QoL) and clinical aspects. METHODS: Data from the Perceived Family Support Inventory (IPFS) of 130 PWEs were related to the clinical variables, QOLIE-31 scores, and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) with statistical tests, with p < 0.05. RESULTS: The mean age was 49.9 ± 17.2 years, and the duration of epilepsy was 20.8 ± 15.4 years. The presence of depression (scores ≥ 15) was associated with lower family support. Being married and non-occurrence of depression were the variables associated with a higher IPFS score (R = 0.2112), in the multiple linear regression. CONCLUSION: The perception of greater family support was associated with demographic aspects, the absence of depression, and better QoL. Family relationships may play an essential role in health adjustment behaviors and QoL in epilepsy.

ANTECEDENTES: A percepção do suporte familiar nas doenças crônicas pode ser relevante. OBJETIVO: Avaliar em pacientes adultos com epilepsia (PCE) a percepção do suporte familiar e relacioná-la com os aspectos clínicos e com a qualidade de vida (QV). MéTODOS: Os dados do Inventário de Percepção de Suporte Familiar (IPSF) de 130 PCE foram relacionados com as variáveis clínicas, os escores do QOLIE-31 e com o Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), com testes estatísticos, com p < 0.05. RESULTADOS: A idade média foi 49.9 ± 17.2 anos e o tempo de epilepsia foi de 20.8 ± 15.4 anos. Escores ≥ 15 no NDDI-E (presença de depressão) associaram-se a menor suporte familiar. Ser casado e não ter depressão são as variáveis associadas a maiores escores no IPSF (R = 0.2112), na regressão linear múltipla. CONCLUSãO: A percepção de maior suporte familiar associou-se à aspectos demográficos, a ausência de depressão e a melhor QV. As relações familiares podem ter papel essencial nos comportamentos de ajustamento na saúde e na QV na epilepsia.

Cognition and obesity in adults with epilepsy.

Introduction: Objective: to assess the occurrence of overweight/obesity in patient with epilepsy (PWEs) and to relate it to cognitive aspects and clinical variables. Methodology: the measurements of waist circumference, calf circumference, arm circumference, and the body mass index were related to the scores of the Mini-Mental State Examination and the Brief Cognitive Battery-Edu, as well as to the clinical variables of 164 PWEs, with a significance level of p < 0.05. Data were compared to a similar control group (CG) comprising 71 cases. Linear and multiple logistic regression models were used to assess factors related to cognitive aspects. Results: the mean age of the PWEs was 49.8 ± 16.6 years with a mean length of epilepsy of 22 ± 15.9 years. Overweight/obesity occurred in 106 (64.6 %) PWEs and in 42 (59.1 %) CG subjects. The PWEs had a worse performance in several cognitive functions when compared to CG subjects. In the PWEs, overweight/obesity was associated with lower educational level, older age, and cognitive impairment. Greater waist circumference, overweight, age at the first seizure, and use of polytherapy with antiseizure medications were predictive factors of memory impairment in multiple linear regression. Greater arm and calf circumference values were associated with better performance in several cognitive areas. Conclusion: the occurrence of overweight/obesity in PWEs and CG subjects was high. Cognitive impairment occurred in a high number of PWEs and was associated with overweight, greater waist circumference values, and clinical aspects of epilepsy. Better cognitive performance was associated with greater arm and calf circumference.

Introducción: Objetivo: evaluar la ocurrencia de sobrepeso/obesidad en pacientes con epilepsia y relacionarla con aspectos cognitivos y variables clínicas. Metodología: las medidas de circunferencia de cintura, circunferencia de pantorrilla, circunferencia de brazo e índice de masa corporal se relacionaron con los puntajes del Mini-Mental State Exam y de la Batería Cognitiva Breve-Edu, así como con las variables clínicas de 164 pacientes con epilepsia, con un nivel de significación de p < 0,05. Los datos se compararon con un grupo de control similar (GC) compuesto por 71 casos. Se utilizaron modelos de regresión logística lineal y múltiple para evaluar factores relacionados con aspectos cognitivos. Resultados: la edad media de las pacientes con epilepsia fue de 49,8 ± 16,6 años con una duración media de la epilepsia de 22 ± 15,9 años. Presentaron sobrepeso/obesidad 106 (64,6 %) pacientes con epilepsia y 42 (59,1 %) sujetos del GC. Los pacientes con epilepsia tuvieron un peor desempeño en varias funciones cognitivas en comparación con los sujetos del GC. En las pacientes con epilepsia, el sobrepeso/obesidad se asoció con menor nivel educativo, mayor edad y deterioro cognitivo. La mayor circunferencia de la cintura, el sobrepeso, la edad de la primera convulsión y el uso de politerapia con medicamentos anticonvulsivos fueron factores predictivos del deterioro de la memoria en la regresión lineal múltiple. Los valores mayores de circunferencia del brazo y la pantorrilla se asociaron con un mejor rendimiento en varias áreas cognitivas. Conclusión: la incidencia de sobrepeso/obesidad en sujetos pacientes con epilepsia y GC fue alta. El deterioro cognitivo ocurrió en un alto número de pacientes con epilepsia y se asoció con sobrepeso, mayores valores de circunferencia de la cintura y aspectos clínicos de la epilepsia. Un mejor rendimiento cognitivo se asoció con una mayor circunferencia del brazo y la pantorrilla.

Resistance exercise training ameliorates chronic kidney disease outcomes in a 5/6 nephrectomy model.

Chronic kidney disease (CKD) is defined by decreased glomerular filtration rate (GFR) or increased albumin excretion leading to renal injury. However, exercise training is an important non-pharmacological intervention that ameliorates and protects against Diabetes Mellitus, cardiovascular disease, and CKD. AIM: Our aim was to evaluate the capability of resistance exercise training (RET) to improve CKD outcomes and the contribution of the renal and muscular Akt/mTOR signaling pathway for RET beneficial effects on a CKD model. MAIN METHODS: Male Wistar rats were subjected to RET, followed for 10 weeks, and randomly divided into 5 groups: Sham: Sham-operated; sedentary and nephrectomy (5/6Nx) (SNS); exercising post-5/6Nx (SNE); exercising pre-5/6Nx (ENS); exercising pre- and post-5/6Nx (ENE). The systolic blood pressure (BP) was measured. Creatinine, proteinuria, and blood urea nitrogen (BUN) were evaluated. After euthanasia Renal and muscular Akt/mTOR signaling pathways were analyzed. KEY FINDING: Our study showed that the SNS presented renal injury, hypertension, weight and muscular mass loss and a higher mortality rate. SNS group also decreased renal IL-10 and increased TNF-alfa and TGF-Beta. Renal AKT, mTOR, and rpS6 pathway were increased, PTEN was decreased on SNS. And muscular Akt and mTOR were decreased on SNS. SIGNIFICANCE: The RET before and after the 5/6Nx ameliorates all these parameters mentioned above, suggesting that RET is a good non-pharmacological approach to diminish complications frequently found in CKD. We also suggest that the AKT-m-TOR pathway can play an important role in these beneficial outcomes of RET on the CKD animal model.

Topical Aminosalicylic Acid Improves Keratinocyte Differentiation in an Inducible Mouse Model of Harlequin Ichthyosis.

Mutations in the lipid transport protein ABCA12 cause the life-threatening skin condition harlequin ichthyosis (HI), which is characterized by the loss of skin barrier function, inflammation, and dehydration. Inflammatory responses in HI increase disease severity by impairing keratinocyte differentiation, suggesting amelioration of this phenotype as a possible therapy for the condition. Existing treatments for HI are based around the use of retinoids, but their value in treating patients during the neonatal period has been questioned relative to other improved management regimens, and their long-term use is associated with side effects. We have developed a conditional mouse model to demonstrate that topical application of the aminosalicylic acid derivatives 5ASA or 4ASA considerably improves HI keratinocyte differentiation without the undesirable side effects of the retinoid acitretin and salicylic acid (aspirin). Analysis of changes in gene expression shows that 4ASA in particular elicits compensatory upregulation of a large family of barrier function-related genes, many of which are associated with other ichthyoses, identifying this compound as a lead candidate for developing topical treatments for HI.

Educational problems related to quantitative EEG changes in benign childhood epilepsy with centrotemporal spikes.

The relationship between educational problems and clinical/electroencephalographic aspects was assessed in 38 children with benign childhood epilepsy with centrotemporal spikes (BECTS). Children were assessed using the School Performance Test; questionnaires on learning difficulties administered to parents and teachers; the Wechsler Intelligence Scale for Children, Third Edition; and EEGs. Absolute and relative amplitudes in the classic bands (quantitative EEG) and characteristics of epileptiform activity on the EEG were examined. Educational problems were observed in 7 (18.4%) children with BECTS. In this subgroup, relative alpha amplitudes at the central and parietal electrodes were lower as compared with those of the BECTS subgroup with normal educational performance and a control group matched for age, gender, and socioeconomic status. The data indicated a possible relationship between alterations in background brain electrical activity and the tendency toward inferior educational performance in children with BECTS. This study suggested that quantitative EEGs are a possible physiological tool in the assessment of cognitive aspects in children with BECTS.

Short-term clinical and immunologic effects of scaling and root planing with Er:YAG laser in chronic periodontitis.

BACKGROUND: Recently, the erbium-doped:yttrium, aluminum, and garnet (Er:YAG) laser has been used for periodontal therapy. This study compared Er:YAG laser irradiation (100 mJ/pulse, 10 Hz, 12.9 J/cm(2)) with or without conventional scaling and root planing (SRP) to SRP only for the treatment of periodontal pockets affected with chronic periodontitis. METHODS: Twenty-one subjects with pockets from 5 to 9 mm in non-adjacent sites were studied. In a split-mouth design, each site was randomly allocated to a treatment group: SRP and laser (SRPL), laser only (L), SRP only (SRP), or no treatment (C). The plaque index (PI), gingival index (GI), bleeding on probing (BOP), and interleukin (IL)-1beta levels in crevicular fluid were evaluated at baseline and at 12 and 30 days postoperatively, whereas probing depth (PD), gingival recession (GR), and clinical attachment level (CAL) were evaluated at baseline and 30 days after treatment. A statistical analysis was conducted (P <0.05). RESULTS: Twelve days postoperatively, the PI decreased for SRPL and SRP groups (P <0.05); the GI increased for L, SRP, and C groups but decreased for the SRPL group (P <0.05); and BOP decreased for SRPL, L, and SRP groups (P <0.01). Thirty days postoperatively, BOP decreased for treated groups and was lower than the C group (P <0.05). PD decreased in treated groups (P <0.001), and differences were found between SRPL and C groups (P <0.05). CAL gain was significant only for the SRP group (P <0.01). GR increased for SRPL and L groups (P <0.05). No difference in IL-1beta was detected among groups and periods. CONCLUSION: Er:YAG laser irradiation may be used as an adjunctive aid for the treatment of periodontal pockets, although a significant CAL gain was observed with SRP alone and not with laser treatment.

Alzheimer's disease: nutritional status and cognitive aspects associated with disease severity.

INTRODUCTION: Alzheimer's pathology is a neurodegenerative disease characterized by cognitive impairment and functional disability that causesprogressive restrictions in daily activities. The present study associates nutritional status with cognitive and clinical aspects of the elderly withmild, moderate and severe Alzheimer's disease (AD). METHODS: data from the Mini Nutritional Assessment (MNA), bioelectrical impedance (BIA), anthropometric measurements, and physical activityindicators were associated with clinical and cognitive aspects of 43 elderly patients with AD. The data were compared to a paired control group (NC) (n = 51) at a significance level of p < 0.05. RESULTS: elderly patients with AD presented lower cognitive performance, higher risk of malnutrition (p = 0.001), lower weight (t-test, p = 0.017) and body mass index (BMI) (p = 0.006), and higher sedentarity (Chi-square, p = 0.040) when compared with the NC. The elderly with AD presented significant reduction in lean body mass (LM) and increased fat mass (FM). As dementia progresses, significant impairment of nutritional indicators is observed. Elderly patients with severe AD present lower weight, BMI, MNA scores and increased body fat mass index and fat mass when compared with those with mild/moderate AD. A correlation was observed between better cognitive performance and weight, BMI, calf circumference and triceps skinfold thickness. CONCLUSION: elderly patients with AD present high sedentarity, risk of malnutrition, lower weight, BMI and LM, and increased FM. There was progressive impairment of nutritional status and cognition as the disease progressed. There is an association between the nutritional variables and cognitive aspects.

Family support in adults with epilepsy / Percepção do suporte familiar em adultos com epilepsia

Abstract Background The perception of family support in chronic disease can be relevant. Objective To assess the perception of family support in adult patients with epilepsy (PWEs) and relate it to quality of life (QoL) and clinical aspects. Methods Data from the Perceived Family Support Inventory (IPFS) of 130 PWEs were related to the clinical variables, QOLIE-31 scores, and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) with statistical tests, with p < 0.05. Results The mean age was 49.9 ± 17.2 years, and the duration of epilepsy was 20.8 ± 15.4 years. The presence of depression (scores ≥ 15) was associated with lower family support.

Large-scale transcriptome analyses reveal new genetic marker candidates of head, neck, and thyroid cancer.

A detailed genome mapping analysis of 213,636 expressed sequence tags (EST) derived from nontumor and tumor tissues of the oral cavity, larynx, pharynx, and thyroid was done. Transcripts matching known human genes were identified; potential new splice variants were flagged and subjected to manual curation, pointing to 788 putatively new alternative splicing isoforms, the majority (75%) being insertion events. A subset of 34 new splicing isoforms (5% of 788 events) was selected and 23 (68%) were confirmed by reverse transcription-PCR and DNA sequencing. Putative new genes were revealed, including six transcripts mapped to well-studied chromosomes such as 22, as well as transcripts that mapped to 253 intergenic regions. In addition, 2,251 noncoding intronic RNAs, eventually involved in transcriptional regulation, were found. A set of 250 candidate markers for loss of heterozygosis or gene amplification was selected by identifying transcripts that mapped to genomic regions previously known to be frequently amplified or deleted in head, neck, and thyroid tumors. Three of these markers were evaluated by quantitative reverse transcription-PCR in an independent set of individual samples. Along with detailed clinical data about tumor origin, the information reported here is now publicly available on a dedicated Web site as a resource for further biological investigation. This first in silico reconstruction of the head, neck, and thyroid transcriptomes points to a wealth of new candidate markers that can be used for future studies on the molecular basis of these tumors. Similar analysis is warranted for a number of other tumors for which large EST data sets are available.

The blockade of cyclooxygenases-1 and -2 reduces the effects of hypoxia on endothelial cells.

Hypoxia activates endothelial cells by the action of reactive oxygen species generated in part by cyclooxygenases (COX) production enhancing leukocyte transmigration. We investigated the effect of specific COX inhibition on the function of endothelial cells exposed to hypoxia. Mouse immortalized endothelial cells were subjected to 30 min of oxygen deprivation by gas exchange. Acridine orange/ethidium bromide dyes and lactate dehydrogenase activity were used to monitor cell viability. The mRNA of COX-1 and -2 was amplified and semi-quantified before and after hypoxia in cells treated or not with indomethacin, a non-selective COX inhibitor. Expression of RANTES (regulated upon activation, normal T cell expressed and secreted) protein and the protective role of heme oxygenase-1 (HO-1) were also investigated by PCR. Gas exchange decreased partial oxygen pressure (PaO2) by 45.12 +/- 5.85% (from 162 +/- 10 to 73 +/- 7.4 mmHg). Thirty minutes of hypoxia decreased cell viability and enhanced lactate dehydrogenase levels compared to control (73.1 +/- 2.7 vs 91.2 +/- 0.9%, P < 0.02; 35.96 +/- 11.64 vs 22.19 +/- 9.65%, P = 0.002, respectively). COX-2 and HO-1 mRNA were up-regulated after hypoxia. Indomethacin (300 microM) decreased COX-2, HO-1, hypoxia-inducible factor-1alpha and RANTES mRNA and increased cell viability after hypoxia. We conclude that blockade of COX up-regulation can ameliorate endothelial injury, resulting in reduced production of chemokines.

Event related potentials during the visual discrimination of words and pseudowords by children.

Event related potentials (ERPs) in reading were studied in children in a word and pseudoword discriminating task. Seventy-nine children (9 to 11 year old), all with no elements suggesting brain injury and with school performance compatible with their age were studied. The ERP were registered as there were presented, visually, successively and in a random manner, 100 words and 100 pseudowords. For each stimulus the child pressed a key corresponding to the discrimination between word and pseudoword. The register was carried out for the electrodes of the 10-20 system and the mean amplitudes and latency peaks measured and also the amplitude from 200 to 550 milliseconds. The most significant differences between the ERPs occurred in Cz, with greater negativity for the mean of the amplitude between 425 and 550 milliseconds for pseudowords (N400). The N400 was more precocious in 11 year old. The influence of age was thus evident and also the differences in ERPs between words and pseudowords.
