Intellectual, Psychological, and Clinical Predictors of Quality of Life in Patients with Epilepsy from a Level IV Epilepsy Center in South Florida

Objective

To examine clinical, cognitive, and psychological predictors of Quality of Life (QOL) among Hispanics and non-Hispanics with epilepsy.

Participants and Method

Data was collected from 90 patients (52 Hispanic; H, 38 Non-Hispanic; NH) diagnosed with epilepsy and referred for neuropsychological evaluation that included measures of depression (BDI-II), anxiety (BAI), and QOL using the Personal Impact of Epilepsy Scale (PIES). We conducted multiple linear regression models with patient’s full-scale IQ, age of seizure onset, duration of seizure disorder, and anxiety and depression symptom severity entered as predictors, with the PIES as outcome measure.

Results

There were no significant differences between H and NH on any demographic or clinical variable except for longer duration of seizure disorder (t = 2.20, p = 0.03) in H. For the complete sample, higher FSIQ predicted better QOL in relation to the perceived disabling effects of seizures (β = .28, p =.02), higher BDI-II scores predicted more negative medication side effects and greater mood related disruption in QOL (β = -2.27, p =.03; β = -3.82, p =.00), and higher BAI scores were the best predictor for worse overall QOL (β = -.29, p = .05). When the sample was divided according to ethnic background, longer seizure duration was associated with the adverse effects of less medication in the H group (β = .32, p =.04), with all other findings being identical to those of the complete sample. When results for NH patients were analyzed, none of the intellectual, psychological and clinical variables were significantly associated with any of the QOL scales; however, the relationship between the BAI and comorbid mood dysfunction approached significance (β = -1.45, p = .059).

Conclusions

Our data indicates that overall QOL was primarily predicted by the severity of anxiety symptoms, but not influenced by overall intelligence, symptoms of depression, and clinical seizure variables.

A31 Diversity change of influenza A (H3N2) strains circulating in Brazil during 2017–8: What to expect in the coming winter?

The H3N2 subtype of influenza A (H3N2) was the predominant strain during the early months of the 2017 influenza epidemic in Brazil. In Australia, it was responsible for a strong and prolonged 2017 season and reached the Northern hemisphere causing an intense 2017/8 influenza season. Several genetic and antigenic A(H3N2) variants were circulating, which made the decision about which strain to incorporate into the influenza vaccine challenging. For 2018, the WHO selected a new H3N2 strain, A/Singapore/INFIMH-16-0019/2016-like, to replace the strain A/HongKong/4801/2014-like in the Southern Hemisphere trivalent vaccine. The aim of this study was to describe the genetic diversity of influenza A (H3N2) viruses circulating in Brazil between January 2017 and January 2018, checking the match between the vaccines and worldwide circulating strains with the Brazilian influenza strains. Hemagglutinin gene sequencing of the influenza A (H3N2) was performed, followed by a phylogenetic reconstruction using additional database sequences to define genetic groups and compare with other worldwide circulating strains. We observed a large diversity of H3N2 genetic clusters, including 3C.2a, 3C.2a1, 3C.3a, and their subgroups. During the 2016–7, inter-epidemic and 2017 epidemic period the cluster most frequently detected belonged to clade 3C.2a1 (148/185; 80.0%), a distinct group related to the 2017 vaccine strain A/HongKong/4801/2014-like (3C.2a). However, the genetic profile changed during the study period and in the inter-epidemic season 2017–8 the most commonly detected genetic group was the 3C.2a cluster (43/58; 74.1%). Inside this cluster, the majority (34/43; 79.1%) of strains belonged to a single genetic 3C.2a subgroup 2 (3C.2a2), bearing antigenic substitutions T131K and R142K (site A) and R261Q (site E). The dominance of this 3C.2a2 in the 2017–8 inter-epidemic period in Brazil was similar to the 2017–8 season in Europe and Canada according their surveillance data. The new vaccine strain has five to six antigenic changes in comparison to the predominant 3C.2a2 circulating in South America since September 2017 until now. It is possible that the vaccine mismatch will not protect the population against a majority of circulating strains. Surveillance of the vaccine effectiveness supported by antigenic and serological analysis are necessary to prove this hypothesis. However, this highlights the difficulty of vaccine strain selection and highlights the need for of a universal influenza vaccine.

Oral feeding of Lactobacillus bulgaricus N45.10 inhibits the lung inflammation and airway remodeling in murine allergic asthma: Relevance to the Th1/Th2 cytokines and STAT6/T-bet

Asthma is a chronic disease with impacts on public health. It affects the airways causing pulmonary inflammation mediated by CD4 T cells type Th2, eosinophilia, mucus hypersecretion, and elevated IgE. The unbalance between cytokines and transcription factors is an important feature in asthma. Probiotics has gaining highlight as a therapy for chronic diseases. Thus, we investigate the Lactobacillus bulgaricus (Lb) effect in murine allergic asthma. BALB/c-mice were sensitized to ovalbumin (OA) on days 0 and 7 and were challenged from day 14-28 with OA. Mice received Lb seven days prior to sensitization and it was kept until day 28. The Lb attenuated the eosinophils infiltration, mucus and collagen secretion, IgE production, pro-inflammatory cytokines, TLR4 expression, GATA3, STAT6 and RORγt in lung. Otherwise, Lb increased the anti-inflammatory cytokines, the T-bet and foxp3. Finally, Lb attenuated the allergic asthma-induced inflammation and airway remodeling by interfering on Th1/Th2 cytokines and STAT6/T-bet transcription factors.

Oral Management of Steinert's Disease and Role of Anxiolysis

BACKGROUND

Myotonic dystrophy type I (DM1) is a genetic autosomal dominant disorder; malignant hyperthermia is a possible complication. It may occur following administration of some halogenated general anesthetics, muscle relaxants, or surgical stress.

AIM

The purpose of this case report is to evaluate the dental management of patients with Steinert's disease.

CASE REPORT

The patient needed dental extraction. A locore-gional paraperiosteal anesthesia was performed using bupiva-caine without vasoconstrictor and sedation with nitrous oxide. The syndesmotomy of the elements 3.1, 4.1, and 4.2 was executed. The elements were dislocated through a straight lever and avulsed with an appropriate clamp. The socket was courted, washing with saline solution, inserting a fibrin sponge, and applying sutures (silk 3-0).

CONCLUSION

Dental treatment of the patient with Steinert's dystrophy must be carried out under a hospital environment and the use of local anesthetic without vasoconstrictor and with use of nitrous oxide; anxiolysis is recommended.

CLINICAL SIGNIFICANCE

This case report describes the precautions to perform oral surgery in patients with Steinert's disease and emphasizes the role of anxiolysis to avoid episodes of malignant hyperthermia.

Serum Prolactin Levels and Behçet Disease

PURPOSE

To evaluate serum prolactin levels in Behçet disease (BD) and correlate with phenotypic expression of the disease.

METHODS

This was a prospective, nonrandomized comparative trial. Twenty-two patients fulfilling BD Research Committee criteria and 21 healthy control subjects were included. Patients were classified in complete-type or incomplete-type BD subgroups according to clinical characteristics such as recurrent oral ulcers, genital ulcers, skin lesions, and ocular disease. Age, sex, HLA phenotyping, and therapy were recorded for comparative analysis between groups. Serum prolactin levels were determined by electrochemiluminescence immunoassay on a Modular Analytics E170 analyzer.

RESULTS

Prolactinemia was significantly higher (mean=19.34 ng/mL) in BD patients vs controls (mean=9.83 ng/mL) (p=0.009). This value was also statistically higher in complete-type BD sub-group vs controls (p=0.02). Younger patients (<30 y) required corticosteroids plus immunosuppressives more often (75%), suggesting an association between age and disease severity, al-though not statistically significant.

CONCLUSIONS

Results suggest the role of prolactin in BD pathogenesis and its association with disease expression, especially in complete-type BD.

The Importance of Cyclotorsional Changes in Refractive Surgery

Purpose

To provide evidence of the importance of a precise record of torsional alterations in all patients about to undergo refractive surgery and particularly in patients with latent strabismus that may become decompensated due to the dissociation phenomenon produced during different surgical procedures that result in fixation loss.

Methods

Using 3D-VOG video-oculography, the authors analyzed the horizontal, vertical, and torsional movements of each eye after inducing fixation loss in one and both eyes in a patient with well-compensated dissociated vertical deviation (DVD). As the dissociated techniques, the authors used occlusion according to Posner maneuver and the placing of Bagolini filters with increasing densities by means of the Bielschowsky phenomenon, both pathognomonic of DVD.

Results

The authors observed not only horizontal and vertical alterations, but also cyclotorsional alterations which may even exceed 15° depending on the resulting dissociation component.

Conclusions

In view of the obtained results, the authors consider it important to conduct a meticulous study of ocular motility in all patients about to undergo refractive surgery, especially in the case of high astigmatism to rule out possible latent strabismus that may condition cyclotorsional alterations important in refractive surgery.

Photoionization in the time and frequency domain

Ultrafast processes in matter, such as the electron emission after light absorption, can now be studied using ultrashort light pulses of attosecond duration (10−18 seconds) in the extreme ultraviolet spectral range. The lack of spectral resolution due to the use of short light pulses has raised issues in the interpretation of the experimental results and the comparison with theoretical calculations. We determine photoionization time delays in neon atoms over a 40–electron volt energy range with an interferometric technique combining high temporal and spectral resolution. We spectrally disentangle direct ionization from ionization with shake-up, in which a second electron is left in an excited state, and obtain excellent agreement with theoretical calculations, thereby solving a puzzle raised by 7-year-old measurements.

Identifying sources of metal exposure in organic and conventional dairy farming

In humans the main route of exposure to toxic metals is through the diet, and there is therefore a clear need for this source of contamination to be minimized, particularly in food of animal origin. For this purpose, the various sources of toxic metals in livestock farming (which vary depending on the production system) must be taken into account. The objectives of the present study were to establish the profile of metal exposure in dairy cattle in Spain and to determine, by chemometric (multivariate statistical) analysis, any differences between organic and conventional systems. Blood samples from 522 cows (341 from organic farms and 181 from conventional farms) were analysed by inductively coupled plasma mass spectrometry to determine the concentrations of 14 elements: As, Cd, Co, Cr, Cu, Fe, Hg, I, Mn, Mo, Ni, Pb, Se and Zn. In conventional systems the generally high and balanced trace element concentrations in the mineral-supplemented concentrate feed strongly determined the metal status of the cattle. However, in organic systems, soil ingestion was an important contributing factor. Our results demonstrate that general information about the effects of mineral supplementation in conventional farming cannot be directly extrapolated to organic farming and special attention should be given to the contribution of ingestion of soil during grazing and/or ingestion of soil contaminated forage.

Oral health and implant therapy in Parkinson's patients: review

Parkinson's Disease (PD) is one of the most frequent neurodegenerative diseases, second only to Alzheimer's disease. It is a progressive disease that inevitably leads the patient to death, in most cases for pneumonia ab ingestis. It affects 120 people out of 100,000 and more frequently affects men than women. The main symptoms are divided into motor, non-motor and behavioral ones. The main motors symptoms are tremor, bradykinesia and postural instability. Non-motor symptoms include autonomic nervous dysfunction (orthostatic hypotension, cardiac arrhythmia, sexual dysfunction, excessive sweating due to hypothalamic dysfunction, constipation), insomnia, OSAS, and olfactory dysfunction. Behavioral symptoms are depression, dementia and psychosis. The purpose of this study is to evaluate, through a systematic review of literature, the oral health status of the Parkinson's patient compared with the general population with particular reference to the incidence of caries and periodontal disease, the patient's management during dental interventions and the possibility of rehabilitating the patient with implanted therapy.

Marfan Syndrome: oral implication and management

Marfan's Syndrome is a multisistemic pathology of connective tissues, a dominant autosomal transmission, first discovered by a French pediatrician, Antoine Bernard-Jean Marfan, who first found in some of his patients a disproportionate alteration of inferior infertility. This alteration was caused by the mutation of the FBN1 gene, located on the long arm of the chromosome 15, which encodes for an extracellular matrix protein, fibrin-1. Later it was discovered that the disease could occasionally be due also to the mutation of the TGFBR2 gene, which encodes for a TGF-beta receptor 1. The estimated incidence of the disease is 2-3 subjects affected every 10,000, in the absence of predilection ratial, ethnic, geographic and gender. It is believed that some 15,000 people in Italy suffer from Marfan Syndrome. The disease is characterized by a wide range of clinical manifestations that affect different organs. The study evaluates through a literature review the manifestations in the oral cavity of the marfan syndrome and the correct management of the patient during dental maneuvers.

Effect of cryoprotectants and thawing temperatures on chicken sperm quality

There is need for standardization of freezing-thawing protocol for rooster semen to minimize variability among results. Therefore, we aimed to compare effect of four different permeating cryoprotectants and two thawing temperatures (37 vs. 5°C) on sperm post-thaw motility and to analyse combined effect of the best permeating cryoprotectant (P-CPA) with one of four non-permeating cryoprotectants (N-CPA) on post-thaw quality of rooster semen evaluated in vitro. Pooled semen from Ross PM3 rooster heavy line was diluted in Kobidil extender and frozen in cryoprotectant solution containing 6% dimethylacetamide, 7.5% dimethylformamide, 9% N-methylacetamide or 8% ethylene glycol (EG) in liquid nitrogen vapours. To determine the best thawing rate, straws were thawed either at 37 or 5°C. Furthermore, samples were frozen in the presence of the best N-CPA either with 0.75 mol/L ficoll, 0.2 mol/L sucrose, 0.2 mol/L trehalose or 0.05 mol/L glycine. Sperm motility, membrane destabilization and viability were analysed to compare different freezing-thawing conditions. In addition, morphology and ultrastructure analysis were performed to compare fresh and frozen-thawed sperm quality. Our results indicate that the combination of EG and the thawing at 5°C improves (p ≤ .05) sperm post-thaw motility. Moreover, ficoll addition to EG-based freezing extender provided additional beneficial effect (p ≤ .05) on progressive movement and apoptosis incidence. Further work should evaluate different N-CPA concentrations to improve freezing protocol. In addition, fertility evaluation and testing on different chicken lines are needed in order to contribute to animal genetic resources bank.
