Applying Next-Generation Sequencing to Track HIV-1 Drug Resistance Mutations Circulating in Portugal. Viruses 2024; 16:622. [PMID: 38675962 PMCID: PMC11054263 DOI: 10.3390/v16040622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 04/02/2024] [Accepted: 04/06/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND The global scale-up of antiretroviral treatment (ART) offers significant health benefits by suppressing HIV-1 replication and increasing CD4 cell counts. However, incomplete viral suppression poses a potential threat for the emergence of drug resistance mutations (DRMs), limiting ART options, and increasing HIV transmission. OBJECTIVE We investigated the patterns of transmitted drug resistance (TDR) and acquired drug resistance (ADR) among HIV-1 patients in Portugal. METHODS Data were obtained from 1050 HIV-1 patient samples submitted for HIV drug resistance (HIVDR) testing from January 2022 to June 2023. Evaluation of DRM affecting viral susceptibility to nucleoside/tide reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), and integrase strand transfer inhibitors (INSTIs) was performed using an NGS technology, the Vela Diagnostics Sentosa SQ HIV-1 Genotyping Assay. RESULTS About 71% of patients were ART naïve and 29% were experienced. Overall, 20% presented with any DRM. The prevalence of TDR and ADR was 12.6% and 41.1%, respectively. M184V, T215S, and M41L mutations for NRTI, K103N for NNRTI, and M46I/L for PIs were frequent in naïve and treated patients. E138K and R263K mutations against INSTIs were more frequent in naïve than treated patients. TDR and ADR to INSTIs were 0.3% and 7%, respectively. Patients aged 50 or over (OR: 1.81, p = 0.015), originating from Portuguese-speaking African countries (PALOPs) (OR: 1.55, p = 0.050), HIV-1 subtype G (OR: 1.78, p = 0.010), and with CD4 < 200 cells/mm3 (OR: 1.70, p = 0.043) were more likely to present with DRMs, while the males (OR: 0.63, p = 0.003) with a viral load between 4.1 to 5.0 Log10 (OR: 0.55, p = 0.003) or greater than 5.0 Log10 (OR: 0.52, p < 0.001), had lower chances of presenting with DRMs. CONCLUSIONS We present the first evidence on TDR and ADR to INSTI regimens in followed up patients presenting for healthcare in Portugal. We observed low levels of TDR to INSTIs among ART-naïve and moderate levels in ART-exposed patients. Regimens containing PIs could be an alternative second line in patients with intermediate or high-level drug resistance, especially against second-generation INSTIs (dolutegravir, bictegravir, and cabotegravir).

Abstract
A 57-year-old female with a history of malignant mixed Müllerian tumors of the uterus and ovaries developed a fever of unknown origin and neuropsychiatric symptoms. Her EEG showed slow activity in the left temporal region, and brain magnetic resonance imaging revealed limbic encephalitis, leading to the diagnosis of classic paraneoplastic limbic encephalitis (PLE). During our investigation into the underlying cause of the patient's condition, we conducted a PET-CT scan, which revealed the presence of several hypermetabolic lymph nodes. One of these lymph nodes underwent a biopsy, and the results confirmed the presence of metastatic cells, indicating the likelihood of carcinoma, most probably adenocarcinoma of the gynecological tract. PLE should be considered as one of the differential diagnoses in patients with a history of cancer and acute-to-subacute neuronal and psychiatric dysfunction.

Serotonin Type 2a Receptor in the Prefrontal Cortex Controls Perirhinal Cortex Excitability During Object Recognition Memory Recall. Neuroscience 2022; 497:196-205.

Abstract
Previous experiences can drive adaptive behavior based on different characteristics, including contextual ones. Indeed, contextual information can be used as a criterion to guide the recall of the most relevant memory trace and the inhibition of others. The medial Prefontal Cortex (mPFC) has been proposed as an area that plays a pivotal role in regulating the retrieval of memory traces in downstream regions. Also, we have shown that mPFC Serotonin 2a Receptors (5-HT2aR) modulates the retrieval of a contextually guided recognition memory task and modulates the retrieval and reconsolidation of memories in the Perirhinal Cortex (PRH). However, how the mPFC output mediated by the 5-HT2aR activity is modulating memory retrieval in the PRH is a question that remains unclear. To tackle this question, we analyzed neuronal activity in the PRH and mPFC, by measuring expression of the immediate early gene c-Fos. We combined behavioral, pharmacological and immunohistochemical techniques to examine how mPFC 5-HT2aR controls mPFC and the PRH activity. We found that blockade of mPFC 5-HT2aR increase the level of c-Fos expression in the PHR and that this increase correlates with animals' performance in the task. We also found an increase in c-Fos expression in the mPFC after mPFC 5-HT2aR blockade that does not correlate with the animals' behavioral response. However, these changes showed a significant correlation with those observed in the PRH. These results suggest that mPFC 5-HT2aR signaling may modulate the behavioral response during memory recall by controlling the neuronal activation in the PRH.

Defining a Role for G-Protein Coupled Receptor/cAMP/CRE-Binding Protein Signaling in Hair Follicle Stem Cell Activation. J Invest Dermatol 2022; 142:53-64.e3.

Abstract
Manipulation of adrenergic signaling has been shown experimentally and clinically to affect hair follicle growth. In this study, we provide direct evidence that canonical cAMP/CRE-binding protein signaling through adrenergic receptors can regulate hair follicle stem cell (HFSC) activation and hair cycle. We found that CRE-binding protein activation is regulated through the hair cycle and coincides with HFSC activation. Both isoproterenol and procaterol, agonists of adrenergic receptors, show the capacity to activate the hair cycle in mice. Furthermore, deletion of ADRB2 receptor, which is thought to mediate sympathetic nervous system regulation of HFSCs, was sufficient to block HFSC activation. Downstream, stimulation of adenylyl cyclase with forskolin or inhibition of phosphodiesterase to increase cAMP accumulation or direct application of cAMP was each sufficient to promote HFSC activation and accelerate initiation of hair cycle. Genetic induction of a Designer Receptors Exclusively Activated by Designer Drug allele showed that G-protein coupled receptor/GαS stimulation, specifically in HFSCs, promoted the activation of the hair cycle. Finally, we provide evidence that G-protein coupled receptor/CRE-binding protein signaling can potentially act on HFSCs by promoting glycolytic metabolism, which was previously shown to stimulate HFSC activation. Together, these data provide mechanistic insights into the role of sympathetic innervation on HFSC function.

Abstract
Undiagnosed HIV-1 patients still account for 25% of worldwide HIV patients. Studying late presenters (LPs) for HIV care may help to identify characteristics of such patients. The present study aims to identify factors associated with late presentation and late presentation with advanced disease based on a population of patients followed in a Portuguese hospital between 1984 and 2017. Sociodemographic and clinical data from infected patients with HIV-1 aged 18 years and older, followed in Egas Moniz Hospital, in Portugal were collected. Of the 907 patients included in this study, 68.7% were males and the median age was 37 years (interquartile range 30-47). Four hundred fifty-nine patients (50.6%) were LP and, of these, 284 patients (61.9%) were LPAD. The LP population mostly originated from Portugal and sub-Saharan Africa (64.4% and 28.8%; p = .004) and the HIV exposure category, mainly heterosexuals and men have sex with men (57.0% and 24.9%; p < .001). The stage of disease and viral load at diagnosis were significantly associated with both LP and LPAD (p < .001). Factors associated with LP in the logistic regression included age at diagnosis lower than 30 years (adjusted odds ratio [aOR] 0.34; 0.17-0.68; p = .002) and origin from sub-Saharan Africa (aOR 2.24; 1.44-3.50; p < .001). Late presentation is a major obstacle to halt the HIV epidemic. In this population, the majority of newly diagnosed HIV-infected individuals were LPs. Our results characterize vulnerable populations that should be frequently tested for HIV.

The MAPKinase Signaling and the Stimulatory Protein-1 (Sp1) Transcription Factor Are Involved in the Phototherapy Effect on Cytokines Secretion from Human Bronchial Epithelial Cells Stimulated with Cigarette Smoke Extract. Inflammation 2021; 44:1643-1661. [PMID: 33730343 DOI: 10.1007/s10753-021-01448-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 11/01/2019] [Accepted: 03/07/2021] [Indexed: 10/21/2022]
Abstract
The present study was aimed to investigate the phototherapy effect with low-level laser on human bronchial epithelial cells activated by cigarette smoke extract (CSE). Phototherapy has been reported to actuate positively for controlling the generation/release of anti-inflammatory and pro-inflammatory mediators from different cellular type activated by distinct stimuli. It is not known whether the IL-8 and IL-10 release from CSE-stimulated human bronchial epithelium (BEAS) cells can be influenced by phototherapy. Human bronchial epithelial cell (BEAS) line was cultured in a medium with CSE and irradiated (660 nm) at 9 J. Apoptosis index was standardized with Annexin V and the cellular viability was evaluated by MTT. IL-8, IL-10, cAMP, and NF-κB were measured by ELISA as well as the Sp1, JNK, ERK1/2, and p38MAPK. Phototherapy effect was studied in the presence of mithramycin or the inhibitors of JNK or ERK. The IL-8, cAMP, NF-κB, JNK, p38, and ERK1/2 were downregulated by phototherapy. Both the JNK and the ERK inhibitors potentiated the phototherapy effect on IL-8 as well as on cAMP secretion from BEAS. On the contrary, IL-10 and Sp1 were upregulated by phototherapy. The mithramycin blocked the phototherapy effect on IL-10. The results suggest that phototherapy has a dual effect on BEAS cells because it downregulates the IL-8 secretion by interfering with CSE-mediated signaling pathways, and oppositely upregulates the IL-10 secretion through of Sp1 transcription factor. The manuscript provides evidence that the phototherapy can interfere with MAPK signaling via cAMP in order to attenuate the IL-8 secretion from CSE-stimulated BEAS. In addition, the present study showed that phototherapy effect is driven to downregulation of the both the IL-8 and the ROS secretion and at the same time the upregulation of IL-10 secretion. Besides it, the increase of Sp-1 transcription factor was crucial for laser effect in upregulating the IL-10 secretion. The dexamethasone corticoid produces a significant inhibitory effect on IL-8 as well as ROS secretion, but on the other hand, the corticoid blocked the IL-10 secretion. Taking it into consideration, it is reasonable to suggest that the beneficial effect of laser therapy on lung diseases involves its action on unbalance between pro-inflammatory and anti-inflammatory mediators secreted by human bronchial epithelial cells through different signaling pathway.

Abstract
Obesity is linked to other systemic diseases, such as diabetes mellitus, dyslipidemia, and arterial hypertension. These comorbidities increase the risk of developing cardiovascular disease risk. Adipose tissue is a true endocrine organ and releases various pro-inflammatory cytokines. Periodontal disease (PD) is a chronic inflammatory disorder of the gingiva and bone support (periodontal tissues) that surrounds the teeth. The relationship between obesity and an increased risk of developing PD is already known in the literature. Many studies correlated the cardiometabolic risk with periodontal disease. Bariatric surgery is a way to reduce the adipose tissue in obese patients, that meet specific criteria. It has been observed that this type of surgery usually reduces both the systemic inflammation and the cardiometabolic risk. Some authors have hypothesized that, as a result, the progression of periodontal disease is also reduced. Five articles are analyzed in this systematic review. In these papers, the periodontal health before and after the bariatric surgery was compared. However, the conclusion of the previous studies demonstrated a scarce literature and did not confirm the reduction of periodontal disease after bariatric surgery, but a reduction of cardiometabolic risk. Therefore, periodontal disease in no way influences the reduction of cardiovascular risk after bariatric surgery.

Abstract
Calcinosis cutis is a rare and potentially disabling condition characterized by calcium deposition in soft tissues. When associated with autoimmune connective tissue diseases, calcinosis cutis is classified as Dystrophic Calcinosis Cutis (DCC), being its occurrence in systemic lupus erythematosus (SLE) patients fairly uncommon. We report a case of DCC in a 49 years old woman with eleven years evolution SLE that presented with a two years history of multiple painful skin lesions, some of them ulcerated and exhibiting a chalky white-yellow floor, in both hands, forearms, thighs, buttocks, abdomen and left breast. The pelvic X-ray showed soft tissue calcifications and the skin biopsy confirmed the diagnosis of DCC. The patient was treated with diltiazem 240mg/day and a significant regression of the lesions and associated pain was observed. Dystrophic calcinosis cutis is often a painful and disrupting condition in which timely diagnosis and treatment may be quite challenging.

Abstract
Appropriate supplementation of trace minerals is fundamental to enhance the metabolic status of growing animals and promote an adequate expression of genetic potential. Zinc (Zn) is an essential mineral fundamental in many biological processes that are related to growth, energy balance and immunity. The aim of the present study was to analyse the effect of Zn supplementation on growth parameters in small ruminants by using a meta-analytic approach. Sources of heterogeneity were explored using a meta-regression analysis. The final database was integrated from a total of 53 trials. Only indexed articles that provided an effect size measure, variability measure, sample size and randomisation of the procedure were considered. The dependent variables considered for the study were average daily gain (ADG), dry-matter intake (DMI), feed conversion ratio (FCR), final bodyweight, and glucose blood concentration. The exploratory variables included species (sheep and goat), breed, production level, Zn source and dosage. The ‘meta’ package in R statistical software was used to conduct the meta-analyses. For response variables that showed substantial heterogeneity (I2 > 50%), mixed-effect models (meta-regression analysis) were constructed to explore the sources of heterogeneity using the ‘Metafor’ package. DMI was higher in animals supplemented with Zn (>21.08 g/day, P = 0.0001). Breed, species, production level, and dosage reduced heterogeneity of DMI response from I2 = 84.8 to I2 = 48.1%. Zn-supplemented animals showed higher ADG (17.39 g/day, P = 0.001), which was affected by species, breed dosage and Zn-source. Zn supplementation improved feed efficiency, with lower values of FCR (–1.56 g/g, P < 0.0001). There was a positive relationship between the dosage and effect size in all outcome variables (P < 0.05). Zn-proteinate showed the best response in both species to ADG, FCR and final body weight. Our findings of the systematic review concluded that dietary Zn supplementation improves growth performance in small ruminants and their level of response is influenced mainly by species, production level, and Zn-source and dosage.

Abstract
INTRODUCTION Treatment for All recommendations have allowed access to antiretroviral (ARV) treatment for an increasing number of patients. This minimizes the transmission of infection but can potentiate the risk of transmitted (TDR) and acquired drug resistance (ADR). OBJECTIVE To study the trends of TDR and ADR in patients followed up in Portuguese hospitals between 2001 and 2017. METHODS In total, 11,911 patients of the Portuguese REGA database were included. TDR was defined as the presence of one or more surveillance drug resistance mutation according to the WHO surveillance list. Genotypic resistance to ARV was evaluated with Stanford HIVdb v7.0. Patterns of TDR, ADR and the prevalence of mutations over time were analyzed using logistic regression. RESULTS AND DISCUSSION The prevalence of TDR increased from 7.9% in 2003 to 13.1% in 2017 (p < 0.001). This was due to a significant increase in both resistance to nucleotide reverse transcriptase inhibitors (NRTIs) and non-nucleotide reverse transcriptase inhibitors (NNRTIs), from 5.6% to 6.7% (p = 0.002) and 2.9% to 8.9% (p < 0.001), respectively. TDR was associated with infection with subtype B, and with lower viral load levels (p < 0.05). The prevalence of ADR declined from 86.6% in 2001 to 51.0% in 2017 (p < 0.001), caused by decreasing drug resistance to all antiretroviral (ARV) classes (p < 0.001). CONCLUSIONS While ADR has been decreasing since 2001, TDR has been increasing, reaching a value of 13.1% by the end of 2017. It is urgently necessary to develop public health programs to monitor the levels and patterns of TDR in newly diagnosed patients.

Abstract
We demonstrate a novel dispersion-scan (d-scan) scheme for single-shot temporal characterization of ultrashort laser pulses. The novelty of this method relies on the use of a highly dispersive crystal featuring antiparallel nonlinear domains with a random distribution and size. This crystal, capable of generating a transverse second-harmonic signal, acts simultaneously as the dispersive element and the nonlinear medium of the d-scan device. The resulting in-line architecture makes the technique very simple and robust, allowing the acquisition of single-shot d-scan traces in real time. The retrieved pulses are in very good agreement with independent frequency-resolved optical grating measurements. We also apply the new single-shot d-scan to a terawatt-class laser equipped with a programmable pulse shaper, obtaining an excellent agreement between the applied and the d-scan retrieved dispersions.

Oral feeding with probiotic Lactobacillus rhamnosus attenuates cigarette smoke-induced COPD in C57Bl/6 mice: Relevance to inflammatory markers in human bronchial epithelial cells. PLoS One 2020; 15:e0225560.

Abstract
COPD is a prevalent lung disease with significant impacts on public health. Affected airways exhibit pulmonary neutrophilia and consequent secretion of pro-inflammatory cytokines and proteases, which result in lung emphysema. Probiotics act as nonspecific modulators of the innate immune system that improve several inflammatory responses. To investigate the effect of Lactobacillus rhamnosus (Lr) on cigarette smoke (CS)-induced COPD C57Bl/6 mice were treated with Lr during the week before COPD induction and three times/week until euthanasia. For in vitro assays, murine bronchial epithelial cells as well as human bronchial epithelial cells exposed to cigarette smoke extract during 24 hours were treated with Lr 1 hour before CSE addition. Lr treatment attenuated the inflammatory response both in the airways and lung parenchyma, reducing inflammatory cells infiltration and the production of pro-inflammatory cytokines and chemokines. Also, Lr-treated mice presented with lower metalloproteases in lung tissue and lung remodeling. In parallel to the reduction in the expression of TLR2, TLR4, TLR9, STAT3, and NF-κB in lung tissue, Lr increased the levels of IL-10 as well as SOCS3 and TIMP1/2, indicating the induction of an anti-inflammatory environment. Similarly, murine bronchial epithelial cells as well as human bronchial epithelial cells (BEAS) exposed to CSE produced pro-inflammatory cytokines and chemokines, which were inhibited by Lr treatment in association with the production of anti-inflammatory molecules. Moreover, the presence of Lr also modulated the expression of COPD-associated transcription found into BALF of COPD mice group, i.e., Lr downregulated expression of NF-κB and STAT3, and inversely upregulated increased expression of SOCS3. Thus, our findings indicate that Lr modulates the balance between pro- and anti-inflammatory cytokines in human bronchial epithelial cells upon CS exposure and it can be a useful tool to improve the lung inflammatory response associated with COPD.

Abstract
Migration is associated with HIV-1 vulnerability. Objectives: To identify long-term trends in HIV-1 molecular epidemiology and antiretroviral drug resistance (ARV) among migrants followed up in Portugal Methods: 5177 patients were included between 2001 and 2017. Rega, Scuel, Comet, and jPHMM algorithms were used for subtyping. Transmitted drug resistance (TDR) and Acquired drug resistance (ADR) were defined as the presence of surveillance drug resistance mutations (SDRMs) and as mutations of the IAS-USA 2015 algorithm, respectively. Statistical analyses were performed. Results: HIV-1 subtypes infecting migrants were consistent with the ones prevailing in their countries of origin. Over time, overall TDR significantly increased and specifically for Non-nucleoside reverse transcriptase inhibitor (NNRTIs) and Nucleoside reverse transcriptase inhibitor (NRTIs). TDR was higher in patients from Mozambique. Country of origin Mozambique and subtype B were independently associated with TDR. Overall, ADR significantly decreased over time and specifically for NRTIs and Protease Inhibitors (PIs). Age, subtype B, and viral load were independently associated with ADR. Conclusions: HIV-1 molecular epidemiology in migrants suggests high levels of connectivity with their country of origin. The increasing levels of TDR in migrants could indicate an increase also in their countries of origin, where more efficient surveillance should occur.

Effect of increased serum 25(OH)D and calcium on structure and function of post-menopausal women: a pilot study. Arch Osteoporos 2020; 15:154. [PMID: 33009959 PMCID: PMC7532965 DOI: 10.1007/s11657-020-00814-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Accepted: 09/01/2020] [Indexed: 02/03/2023]
Abstract
UNLABELLED The purpose was to determine if increasing serum 25(OH)D and calcium in postmenopausal women increased skeletal muscle size, strength, balance, and functional task performance while decreasing muscle fatigue. PCSA of the vastus lateralis increased and ascent of stairs time decreased after 6 months of increased serum 25(OH)D. PURPOSE The Institute of Medicine recommends ≥ 20 ng/ml of serum 25-hydroxyvitamin D [25(OH)D] for bone and overall health. Serum 25(OH)D levels have been associated with physical performance, postural sway, and falls. The purpose of this study was to determine if increasing postmenopausal women's serum 25(OH)D levels from 20-30 ng/ml to 40-50 ng/ml improved skeletal muscle size, strength, balance, and functional performance while decreasing skeletal muscle fatigue. METHODS Twenty-six post-menopausal women (60-85 years old) with baseline serum 25(OH)D levels between 20 and 30 ng/ml were recruited. Oral over-the-counter (OTC) vitamin D3 and calcium citrate were prescribed to increase subjects' serum 25(OH)D to levels between 40 and 50 ng/ml, serum calcium levels above 9.2 mg/dl, and PTH levels below 60 pg/ml, which were confirmed at 6 and 12 weeks. Outcome measures assessed at baseline and 6 months included muscle physiological cross-sectional area (PCSA), muscle strength, postural balance, time to perform functional tasks, and muscle fatigue. Repeated measures comparisons between baseline and follow-up were performed. RESULTS Nineteen subjects completed the study. One individual could not afford the time commitment for the repeated measures. Three individuals did not take their vitamin D as recommended. Two subjects were lost to follow-up (lack of interest), and one did not achieve targeted serum 25(OH)D. Vastus lateralis PCSA increased (p = 0.007) and ascent of stair time decreased (p = 0.042) after 6 months of increasing serum 25(OH)D levels from 20-30 ng/ml to 40-50 ng/ml. Isometric strength was unchanged. Anterior-posterior center of pressure (COP) excursion and COP path length decreased (p < 0.1) albeit non-significantly, suggesting balance may improve from increased serum 25(OH)D and calcium citrate levels. CONCLUSIONS Several measures of muscle structure and function were sensitive to elevated serum 25(OH)D and calcium levels indicating that further investigation of this phenomenon in post-menopausal women is warranted.

Abstract
Objective
To provide further convergent validity on the Personal Impact of Epilepsy Scale (PIES) Spanish version for use in Hispanics with epilepsy.
Participants and Method
This study included 90 patients (22 Hispanic and Spanish speaking - HSS, 30 Hispanic and English speaking – HES, and 38 non-Hispanic and English speaking – NHES) who were diagnosed with epilepsy and referred by their epileptologist for a comprehensive neuropsychological evaluation that, in addition to cognitive measures, also included the Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), and PIES in English or Spanish- depending on the participant’s primary language. The PIES was created with subscales to measure the effect of seizures, adverse effects of treatment, and comorbidities such as mood disorders on quality of life. We compared scores on the PIES subscales in English and Spanish to determine equivalence. We further examined if language of administration moderated the relationship between PIES subscale scores and depression/anxiety through nonparametric bootstrapping.
Results
There were no significant demographic or clinical differences between the 3 groups examined. ANOVA contrast of mean scores on all PIES subscales between HSS, HES and NHES groups did not reach significance (Seizures F [2,88] = .06 , p = -.93; Medication use F[2,88] = 1.95, p = .14, Comorbidity F[2,88] = .64, p = .52, and total PIES F[2,88] = .19, p = .83). The relationships between PIES and BDI-II/BAI scores were not significantly moderated by language of administration.
Conclusions
Our data suggest clinical equivalency between the English and Spanish versions of the PIES. Furthermore, the relationships between PIES subscales and the BDI-II/BAI were not significantly changed by language of administration. These findings indicate that the Spanish PIES appears to have good convergent validity with the original English version and can be useful in the assessment of quality of life in HSS patients.

Abstract
Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.
