Abstract
PURPOSE/OBJECTIVE(S) Cognitive decline is a significant consequence of stereotactic radiosurgery (SRS) in patients with brain metastases. This is often underrecognized and understudied outside of a formal clinical trial setting as traditional methods are often logistically difficult and need specialized personnel and additional time. To address these challenges, we implemented a prospective study (NCT05504681), incorporating an innovative app-based solution to monitor patient assessments over time, collect patient data easily, and be suitable for cross-cultural use in multiple languages for monitoring post-SRS cognitive decline. MATERIALS/METHODS Patients undergoing SRS from December 2021 to October 2022 were enrolled in this study and completed feedback surveys. The assessments consisted of learning and memory (Hopkins verbal learning test-revised [HVLT-R]), attention and processing speed (Digit symbols modalities test [SDMT]), verbal fluency (Controlled oral word association test [COWAT]) and executive function (Trail making test [TMT]). Baseline and 3-month follow-up testing were conducted in conjunction with routine imaging and clinical assessments. Neurocognitive deterioration (ND) was defined as a decrease of ≥2 standard errors of the mean in any of the tests, without evidence of new intracranial disease. Any differences between the baseline and follow-up assessments were confirmed using the reliable change index. RESULTS A total of 30 patients with median age of 68 (range: 47-87) were enrolled. The median KPS was 90 and 60% were female. 43% of participants had a high school or equivalent level of education. 19 (63%) patients were Hispanic and 43% tested in Spanish. The median number of treated lesions was 2 (1-13) and 7 (23%) patients were treated to ≥5 lesions. The median mean left and right hippocampal doses were 0.3 Gy (0-3 Gy) and 0.2 Gy (0-5.2 Gy), respectively. Overall, 50% of patients met criteria for ND at 3 months. 20% of patients showed ND in HVLT-R-immediate recall (IMM), 23% in HVLT-R-delayed recall (DR), 13% in HVLT-R-recognition (Rec), 3% in COWAT and 20% in TMT. None of the patients had ND in SDMT. The mean relative decline was 28% for HVLT-R- IMM, 34% for HVLT-R-DR, 6% for HVLT-R- Rec, 25% for COWAT, and 21% for TMT. There was no significant association between the number of treated lesions and ND. Based on the feedback results, the majority of patients found the system easy to use (94%) and relevant to their care (73%). Most patients reported that app-based evaluation improved discussions with clinicians (77%), made them feel more in control of their care (79%), and they would recommend the system to other patients (87%). CONCLUSION Our study showed a high incidence of ND using an app-based tool in a patient who underwent SRS and from diverse education and language backgrounds. Patient survey results demonstrated that the tool was easy to use and relevant to the patient's care, especially due to improvements in discussions with clinicians and a sense of being in control of their own care.

Abstract
Background Total knee arthroplasty (TKA) is a cost-effective treatment for the end-stage of knee osteoarthritis. Despite the improvements in this surgery, a significant percentage of patients still report dissatisfaction after knee arthroplasty. Radiological results have been used to predict clinical outcomes and satisfaction after knee replacement. This study aims to evaluate the concordance of a set of radiographic views to assess alignment on total knee arthroplasty. Methods A concordance study was designed with 105 patients (130 TKA) that underwent conventional total knee arthroplasty cruciate-retaining design recruited for the study and scheduled for their annual radiograph control. Measurements were performed on the following radiograph after total knee replacement: full-length standing anteroposterior and lateral radiograph, anteroposterior standing, lateral and axial knee view, and the knee "seated view". A musculoskeletal radiologist and a knee surgeon were recruited to perform the radiological measurement and then estimate the interobserver agreement. Results There was an excellent correlation between Limb Length (LL), Hip-knee-ankle angle (HKA), Sagittal mechanical tibial component alignment (smTA), extension lateral and medial joint space (eLJS and eMJS), 90º flexion lateral and medial joint space (fLJS and fMJS) and Sagittal anatomic lateral view tibial component alignment (saLTA); the good correlation between Mechanical lateral femoral component alignment (mLFA), Sagittal anatomic tibial component alignment (saTA), Sagittal anatomic lateral view femoral component alignment 2 (saLFA2), Patella Height (PH); and moderate to poor correlation for the rest of measurements. Conclusion Excellent and good concordance can be achieved for radiographic measurements in different knee views to assess results after TKA. These findings must encourage future studies to address functional and survival outcomes using all knee views and not just one plane.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
Introduction
Childhood maltreatment (CM) is one of the best described environmental risk factors for developing any psychiatric disorder, while it also confers increased odds for obesity, cardiometabolic disorders and all-cause mortality. Inflammation has been suggested to mediate the widespread clinical effects of CM. Previously, Ligthart et al. (2016) identified a polyepigenetic signature of circulating CRP levels, a measure of chronic low-grade inflammation, that has been reliably associated with a wide array of complex disorders. The study of this biomarker could dilucidate the mechanistic relationship between CM and psychiatric outcomes.
Objectives
Thus, CRP-associated epigenetic modifications were explored regarding proximal exposure to CM.
Methods
Genomic DNA was extracted from peripheral blood mononuclear cells of 157 children and adolescents (7 to 17 years old). Exposure to CM was assessed following the TASSCV criteria. Genome-wide DNA methylation was assessed by means of the EPIC array. Fifty-two out of the 58 original CRP-associated CpG sites surpassed quality control and were included in the analysis. Age, sex, psychopathological status and cell type proportions were included as covariates.
Results
DNA methylation at 12 out of 52 CpG sites (23%) was significantly associated with exposure to CM (p < .05); 8 of these associations survived correction for multiple testing (q < .05).
Conclusions
This is the first study to date to explore the relationship between childhood maltreatment and an epigenetic signature of chronic low-grade inflammation. Our findings underscore the presence of immune dysregulation early after exposure to CM; further studies are needed to assess the long-term clinical implications of this signature in psychiatric patients.
Disclosure
No significant relationships.

Abstract
Introduction
Youth exposed to complex trauma (CT) show an increased risk of psychiatric morbidity, including a wide range of psychiatric disorders. However, to date, there is no specific diagnosis in the DSM-5 that capture the clinical complexity of these patients. Properly, the last version of the ICD-11 includes a diagnosis termed Complex Post-Traumatic Stress Disorder (CPTSD), which considers the pattern of post-traumatic stress symptoms, plus life-impairing disturbances in self-organization (emotion dysregulation, negative self-concept and interpersonal problems). Clinical research about CPTSD, especially in younger population, is still limited.
Objectives
To explore the symptomatology of CPTSD in a sample of youth exposed to CT and its association with worse clinical outcomes.
Methods
187 youth aged 7 to 17 years participated in the EPI_young_stress_project (116 with current psychiatric disorder and 71 healthy controls). CT was evaluated following the TASSCV criteria. To identify CPTSD symptomatology, we performed an exploratory factor analysis including CBCL and TEIQue items. The global level of functioning was measured by CGAS.
Results
Preliminary results pointed that youth exposed to CT showed greater internalizing (p<.001) and externalizing (p<.001) symptomatology. Regardless of their current primary diagnosis based on DSM-5, youth exposed to CT reported more CPTSD symptomatology (p<.001). Moreover, youth with CPTSD showed greater use of psychotropic drugs (p<.001), higher and longer hospitalizations (p=.002) and worse overall functioning (p<.001).
Conclusions
The inclusion of the CPTSD in future versions of mental disorders manuals should increase the implementation of early specific trauma interventions, which may improve victims’ lives and reduce the risk of worse clinical outcomes.

Abstract
OBJECTIVE Vulvovaginal atrophy is frequent, can be bothersome and can impair quality of life in postmenopausal women. The main objective of this prospective, randomized study was to compare the acceptability of low-dose vaginal 17β-estradiol (estradiol) tablets and vaginal promestriene cream in postmenopausal women with moderate-to-severe symptomatic vulvovaginal atrophy. METHODS Overall, 120 patients were randomized to receive estradiol or promestriene (n = 60 per group). Acceptability was assessed with a specific questionnaire. Symptom intensity, the Vaginal Health Index (VHI), vaginal pH and the Vaginal Maturation Index were also evaluated. RESULTS Acceptability was higher for estradiol tablets. Compared to promestriene cream, hygiene and ease of use were greater after 4 weeks (p = 0.011 and p = 0.001, respectively) and after 12 weeks (p = 0.009 and p = 0.011, respectively). Reduction of symptom intensity was greater with estradiol. Both treatments improved the VHI and decreased vaginal pH. However, superficial cell percentages increased significantly (p < 0.001) with estradiol but not with promestriene (p = 0.241), with a statistically significant difference between means (p = 0.004). CONCLUSION Our results support the use of vaginal low-dose estradiol tablets as compared to vaginal promestriene cream for the management of moderate-to-severe symptomatic vulvovaginal atrophy in postmenopausal women.

Abstract
Pulmonary arteriovenous malformations (PAVM), also known as pulmonary arteriovenous fistulas, are abnormal connections between the pulmonary arterial and venous systems. The majority occur secondary to the congenital syndrome hereditary hemorrhagic telangiectasia (HHT), also known as Osler-Weber-Rendu disease. Trauma is an extremely rare etiology of PAVM, comprising less than 1% of all reported cases. Trauma can be associated with both immediate and delayed development of PAVM, and present similarly to PAVM associated with HHT. We report a case of a traumatic PAVM that developed in a patient one year following blunt thoracic trauma with a rib fracture. The patient subsequently developed a rupture of the PAVM, resulting in spontaneous hemothorax. She required multi-unit blood transfusion and multiple thoracostomy tube placements. The patient subsequently underwent a failed attempt at angioembolization of the PAVM. She eventually required a thoracotomy for surgical excision of the PAVM. We discuss the traumatic etiologies, clinical presentation, diagnostic assessments, and therapeutic modalities for the management of PAVM.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

Abstract
Despite use of 7-valent pneumococcal conjugate vaccine, incidence of pleural effusion and empyema (pediatric complicated pneumococcal pneumonia [PCPP]) is reportedly increasing globally. We cultured and performed PCR on 152 pleural fluid samples recovered from pediatric patients in Portugal during 2010–2015 to identify and serotype Streptococcus pneumoniae. We identified only 17 cases by culture, but molecular methods identified S. pneumoniae in 68% (92/135) of culture-negative samples. The most frequent serotypes were 3, 1, and 19A, together accounting for 62% (68/109) of cases. Nineteen cases attributable to 13-valent pneumococcal conjugate vaccine (PCV13) serotypes (mostly serotype 3) were detected among 22 children age-appropriately vaccinated with PCV13. The dominance of the additional serotypes included in PCV13 among PCPP cases in Portugal continues, even with PCV13 available on the private market (without reimbursement) since 2010 and with average annual coverage of 61% among age-eligible children. Our data suggest reduced effectiveness of PCV13 against serotype 3 PCPP.

Abstract
A high rate of recurrence has been described in atypical hemolytic uremic syndrome renal transplant recipients, favored by certain immunosuppressant drugs that can induce complement activation. We present four case series in which three patients were diagnosed pretransplantation and a fourth who had onset in the very early post-transplantation period. The patients received different immunosuppression schedules, and all had improvement after more than 2-years. We suggest the need to stratify the risk of atypical hemolytic uremic syndrome recurrence using genetic studies and the available drugs as the main factors that allow graft survival improvement today.

Abstract
Abstract
Background: The incidence of breast cancer (BC) is low in young women and is characterized by a high prevalence of triple-negative tumors, representing a group of high risk. In this work, we describe the clinicopathological and epidemiological features of triple-negative breast cancer (TNBC) in patients aged ≤35 years.
Methods: We reviewed information of TNBC patients diagnosed at ≤35 years old and treated at the Instituto Nacional de Enfermedades Neoplasicas (between 2000 and 2014). The Cox proportional hazard model was used to identify prognostics factors for DFS and OS.
Results: In total, of 243 out 2007 cases (12.11%) were very young TNBC patients. The median follow-up was 9 years. The median age was 32 years (range: 19-35); 14.8% had obesity. A total of 40 (16.5%) patients had a family history of breast-ovary cancer (FHBOC). Regarding to the clinical-pathological characteristics, 59.4% presented T-Stages 3/4; 65.2% had nodal involvement and 7 patients (2.9%) had bilateral BC. Most of patients were diagnosed at Clinical Stage (CS) III (50.8%). The most common histological subtype the was ductal invasive carcinoma (92.1%), followed by medullar (4.5%) and lobulillar (1.7%). A high histological grade was frequent (84.7%), while 71 cases (49%) were diagnosed with vascular permeation and 55 (48.2%) with macrometastasis in lymph nodes. The majority of patients underwent mastectomy (60.2%) compared to lumpectomy (39.8%). Locoregional relapse and distant metastasis were reported in 30.9% and 49.4% of cases, respectively. The most frequent sites of metastases were lung (14.8%) and brain (11.5%). In the multivariate analysis, only N3 stage was associated with a poor outcome in terms of (N0 vs N3, HR=7.89, 95%CI:2.76-22.56, p<0.001). Variables associated with the risk of death were N stage (P<0.001 for N0 vs N3), neoadjuvant chemotherapy (P<0.027), adjuvant chemotherapy (P<0.001), and radiotherapy (P=0.008).
Conclusions: TNBC in very young Peruvian women was characterized by advanced stage at diagnosis. In these patients, nodal involvement was the most important prognostic factor for DFS. It presents distinctive characteristics and poorer outcomes in terms of DFS and OS.

Abstract
BACKGROUND Presently, the bottleneck in the deployment of high-throughput sequencing technology is the ability to analyse the increasing amount of data produced in a fit-for-purpose manner. The field of microbial bioinformatics is thriving and quickly adapting to technological changes, which creates difficulties for nonbioinformaticians in following the complexity and increasingly obscure jargon of this field. AIMS This review is directed towards nonbioinformaticians who wish to gain understanding of the overall microbial bioinformatic processes, from raw data obtained from sequencers to final outputs. SOURCES The software and analytical strategies reviewed are based on the personal experience of the authors. CONTENT The bioinformatic processes of transforming raw reads to actionable information in a clinical and epidemiologic context is explained. We review the advantages and limitations of two major strategies currently applied: read mapping, which is the comparison with a predefined reference genome, and de novo assembly, which is the unguided assembly of the raw data. Finally, we discuss the main analytical methodologies and the most frequently used freely available software and its application in the context of bacterial infectious disease management. IMPLICATIONS High-throughput sequencing technologies are overhauling outbreak investigation and epidemiologic surveillance while creating new challenges due to the amount and complexity of data generated. The continuously evolving field of microbial bioinformatics is required for stakeholders to fully harness the power of these new technologies.

Abstract
AIM To evaluate the therapeutic effects of dietary krill oil supplementation in modulation of oxidative stress components and DNA oxidative damages marker in cafeteria diet-overfed-rats. MATERIAL AND METHODS Eighteen aging male Wistar rats were divided into three groups of six each and were exposed for the ensuing 8 weeks to one of the diets: control group (TS) which was submitted to standard chow (330kcal/100g), containing 24% of proteins, 5% of lipids and 70% of carbohydrates. Cafeteria standard group (TC) exposed to cafeteria diet (420kcal/100g). The last group received a cafeteria diet enriched in oral force-feeding krill oil 2% (CK). The plasma and tissues pro-oxydant status were assessed by assaying thiobarbituric acid reactive substances, hydroperoxydes, and isoprostans. The determination of DNA oxidative damages was evaluated by the measurement of the major products of DNA oxidation (8-OHdG). RESULTS Exposure to a cafeteria diet increases the metabolic response to the radical attack and DNA oxidative damages in both plasma and key tissues involved in antioxidant defense. Krill oil supplementation in cafeteria diet relieves oxidative stress and DNA damages by lowering several lipid peroxidation components and the main marker of DNA oxidation in obese rats.

Abstract
The cascade of transduction of hypoxia and hypercapnia, the natural stimuli to chemoreceptor cells, is incompletely understood. A particular gap in that knowledge is the role played by second messengers, or in a most ample term, of modulators. A recently described modulator of chemoreceptor cell responses is the gaseous transmitter hydrogen sulfide, which has been proposed as a specific activator of the hypoxic responses in the carotid body, both at the level of the chemoreceptor cell response or at the level of the global output of the organ. Since sulfide behaves in this regard as cAMP, we explored the possibility that sulfide effects were mediated by the more classical messenger. Data indicate that exogenous and endogenous sulfide inhibits adenyl cyclase finding additionally that inhibition of adenylyl cyclase does not modify chemoreceptor cell responses elicited by sulfide. We have also observed that transient receptor potential cation channels A1 (TRPA1) are not regulated by sulfide in chemoreceptor cells.

Abstract
We studied the bacterial characteristics and incidence of invasive infections caused by group B streptococci (GBS) in adults in Iceland in 1975-2014. A total of 145 isolates were characterized by serotyping, antimicrobial susceptibility, multilocus sequence typing and surface protein gene profiling. Disease incidence increased during the studied period (p <0.001), reaching 2.17 cases/100 000 person-years in 2013-14. Overall, serotype Ia was the most frequently found (23%), but serotypes Ib, II, III and V showed similar prevalence (14%-17%). Although there were notable changes in the proportion of most serotypes during the study period, only the decline of serotype III was statistically supported (p = 0.003) and was reflected in a decrease of clonal complexes CC17 and CC19 that included most serotype III isolates (p <0.04). On the other hand, the increase in frequency of CC1 was caused by two lineages expressing distinct serotypes: ST1/V/alp3 and ST196/IV/eps. Underlying the relative stability of serotype Ia were major changes in the lineages expressing this serotype, with an increase in the relative importance of CC23, including both ST23/Ia/eps and ST24/Ia/bca lineages, and a decrease in CC7. Nine cases of invasive GBS disease were caused by ST7, of possible zoonotic origin. All isolates were susceptible to penicillin. Rates of erythromycin and clindamycin resistance were 8.3% and 9.7%, respectively. An over-representation of resistance solely to clindamycin was associated with the unusual lsaC gene and serotype III ST19/rib lineage (p <0.001).

Abstract
The blood-brain barrier (BBB) is necessary for the proper function of the brain. Its maintenance is regulated by endogenous factors. Recent evidences suggest prolactin (PRL) regulates the BBB properties in vitro, nevertheless no evidence of these effects have been reported in vivo. The aim of this study was to evaluate the role of PRL in the maintenance of the BBB in the rat. Male Wistar rats were treated with Bromocriptine (Bromo) to inhibit PRL production for 28days in the absence or presence of lipopolysaccharide (LPS). BBB permeability was evaluated through the Evans Blue dye and fluorescein-dextran extravasation as well as through edema formation. The expression of claudin-5, occludin, glial fibrillary acidic protein (GFAP) and the PRL receptor (PRLR) was evaluated through western blot. Bromo reduced the physiological levels of PRL at 28days. At the same time, Bromo increased BBB permeability and edema formation associated with a decrement in claudin-5 and occludin and potentiated the increase in BBB permeability induced by LPS. However, no neuroinflammation was detected, since the expression of GFAP was unchanged, as well as the expression of the PRLR. These data provide the first evidence that inhibition of PRL with Bromo affects the maintenance of the BBB through modulating the expression of tight junction proteins in vivo.

Abstract
Immunologic and genetic factors are involved in HIV-1/AIDS pathogenesis. Defensins are key molecules in innate immunity that participate in the control and/or development of infection and disease. Using PCR-RFLPs, we determined the association between HIV-1/AIDS and human β-defensin 1 (DEFB1) 5'UTR -52 G/A (rs1799946), -44 C/G (rs1800972), and -20 G/A (rs11362) polymorphisms in three groups of women from the state of Sinaloa, located in the Northwest region of Mexico: i) healthy blood donors; ii) sex-workers; and iii) HIV-1 patients. The -52GG genotype was more frequent in blood donors than in patients (p= 0.023; Odds Ratio, OR= 0.49; 95% CI= 0.25-0.95), whereas the - 52GA genotype was significantly higher in patients (p= 0.013; OR= 2.03; 95% CI= 1.11-3.79, statistical power SP= 98.8%), as well as the frequencies of -20A allele (p= 0.017; OR= 1.60; 95% CI= 1.06-2.40), -20AA genotype (p= 0.047; OR = 2.02; 95% CI= 0.93-4.33) and the ACA haplotype with respect to healthy blood donors (p= 0.000012; OR= 5.82; 95% CI= 2.33-16.43, SP= 99.89%) and sex-workers (p= 0.019; OR= 2.18; 95% CI= 1.07-4.46). Conversely, the ACG haplotype was higher in healthy blood donors than in patients (p= 0.009; OR= 0.55; 95% CI= 0.34-0.89). In addition, the -44CC genotype was associated with a low plasma viral load (p= 0.015), whereas AGA, AGG and GGA haplotypes were more prevalent in individuals with high CD4 counts (p= 0.004, 0.046, and 0.029, respectively). These findings associate DEFB1 5'UTR polymorphisms with HIV-1/AIDS in Mexican women for the first time.

Abstract
Malignancies of the lungs, both primary and metastatic, are the leading cause of death worldwide. Over 1.5 million new cases of primary lung cancer are diagnosed annually worldwide with a dismal five-year survival rate of approximately 15%, which remains unchanged despite major efforts and medical advances. As expected, survival for patients with lung metastases is even worse at about 5%. Early detection and staging are fundamental in improving survival rates and selecting the most effective treatment strategies. Recently, nanoparticles have been developed for imaging and treating various cancers, including pulmonary malignancies. In this work, three different examples of nanoparticle configurations for cancer theranosis are presented, namely conventional spherical polymeric nanoparticles with a diameter of ~ 150 nm; and discoidal mesoporous silicon nanoconstructs and discoidal polymeric nanoconstructs with a diameter of ~ 1,000 nm and a height of 400 and 500 nm, respectively. The spherical nanoparticles accumulate in tumors by means of the well-known enhanced permeation and retention effect, whereas sub-micrometer discoidal nanoconstructs are rationally designed to adhere firmly to the tortuous tumor vasculature. All three nanoparticles are characterized for their in vivo performance in terms of magnetic resonance, positron-emission tomography (PET), and optical imaging. Preliminary data on the in vivo and ex vivo PET/CT imaging of breast cancer metastasis in the lungs using discoidal nanoconstructs is presented. In conclusion, opportunities for nanoparticle-based theranosis in primary lung cancer and pulmonary metastasis are presented and discussed.

Abstract
BACKGROUND Malabsorption of l-T4 is a major clinical problem. Changes in gastric pH caused by several medical illnesses are associated with difficulties in the control of patients with hypothyroidism receiving the hormone. Means to correct these alterations would be of clinical value. OBJECTIVES Our objective was to study the effect of vitamin C on the absorption of l-T4 in patients with hypothyroidism and gastritis. DESIGN Thirty-one patients with hypothyroidism, 28 females age 47.5 ± 13.5 (mean ± SD) years and 3 males age 55.7 ± 11.2 years ingested the dose of l-T4 in 120 mL water containing or not containing 500 mg vitamin C in a solution of pH 2.9 ± 0.1 (mean ± SD). Serum concentrations of free T4 and TSH were measured at the end of 3 periods of 2 months each, 2 controls and 1 vitamin C. Serum total T3 was measured in 16 of the patients, before and at the end of the vitamin C period. Serum TSH and free T4 and T3 were measured by a solid-phase, enzyme-labeled chemiluminescent competitive immunoassay All patients had gastrointestinal pathology and were not in good control when taking l-T4 before the study, and 23 had autoimmune thyroiditis or idiopathic hypothyroidism. The median l-T4 dose was 100 μg with an interquartile range of 50 μg. The protocol was reviewed and approved by our institution's ethics committee. Patients were asked to sign a written consent to participate in the study. RESULTS Serum concentrations of TSH, free T4, and T3 improved while on vitamin C. Serum TSH decreased in all patients (control, 11.1 [10.5] μIU/mL, median [interquartile range]), vitamin C 4.2 (3.7) μIU/mL, P = .0001), and it was normalized in 17 patients (54.8%). The average decrease was 69.2%. Serum T4 was higher with vitamin C in 30 of the 31 patients (control, 1.1 [0.3] ng/dL; vitamin C, 1.3 [0.3] ng/dL; P < .0001), and serum T3 increased as well in all 16 patients in whom it was measured (control, 60.5 [16.5] ng/dL; vitamin C, 70 [21] ng/dL; P < .005). CONCLUSIONS In patients with hypothyroidism and gastrointestinal pathology, vitamin C improves the abnormalities in serum free T4, T3, and TSH concentrations. This approach is helpful in the management of these patients.

Abstract
Epidemiology and clinical characteristics of invasive Group A streptococcal infections (IGASI) are highly variable. Long-term studies are needed to understand the interplay between epidemiology and virulence. In a population-based study of IGASI in Iceland from 1975 to 2012, 288 cases were identified by positive cultures from normally sterile body sites. Charts were reviewed retrospectively and emm-types of viable Streptococcus pyogenes isolates (n=226) determined. Comparing the first and last decade of the study period, IGASI incidence increased from 1.09 to 3.96 cases per 100,000 inhabitants per year. The most common were emm types 1 (25%), 28 (11%) and 89 (11%); emm1 strains were most likely to cause severe infections. Infections in adults were significantly more likely to be severe during the seasonal peak from January to April (risk ratio: 2.36, 95% confidence interval: 1.34–4.15). Significant seasonal variability in severity was noted among patients with diagnosis of sepsis, respiratory infection and cellulitis, with 38% of severe infections in January to April compared with 16% in other months (p<0.01). A seasonal increase in severity of IGASI suggested that generalised seasonal increase in host susceptibility, rather than introduction of more virulent strains may play a role in the pathogenesis of these potentially fatal infections.

Abstract
Preoperative use of levosimendan in cardiac surgery patients is one of the most attractive therapeutic alternatives in subjects with left or right ventricular dysfunction. Our review explores the pharmacological bases and clinical evidence for the use of levosimendan, with the intention of making a series of recommendations regarding its use in preoperative optimization prior to cardiac surgery. We carried out a survey of 102 Spanish anesthesiologists in order to shed light on the grey areas regarding the use of this drug prior to surgery. Our findings suggest that levosimendan is recommended for patients with severe left or right ventricular dysfunction, moderate left ventricular dysfunction in which Intra-aortic Balloon Counterpulsation (IABC) is necessary and severe pulmonary hypertension. Administration of levosimendan prior to surgical cardiac intervention without an initial bolus reduces the likelihood of complications.

Abstract
Advances in typing methodologies have been the driving force in the field of molecular epidemiology of pathogens. The development of molecular methodologies, and more recently of DNA sequencing methods to complement and improve phenotypic identification methods, was accompanied by the generation of large amounts of data and the need to develop ways of storing and analysing them. Simultaneously, advances in computing allowed the development of specialised algorithms for image analysis, data sharing and integration, and for mining the ever larger amounts of accumulated data. In this review, we will discuss how bioinformatics accompanied the changes in bacterial molecular epidemiology. We will discuss the benefits for public health of specialised online typing databases and algorithms allowing for real-time data analysis and visualisation. The impact of the new and disruptive next-generation sequencing methodologies will be evaluated, and we will look ahead into these novel challenges.

Abstract
The profiling of the superantigen (SAg) encoding genes has been frequently used as a complementary typing method for group A streptococci (GAS), but a confusing gene nomenclature and a large diversity of primers used in screening has led to some conflicting results. The aim of this work was to develop a polymerase chain reaction (PCR) method capable of efficiently amplifying all the known allelic variants of these genes, and to evaluate the congruence of this methodology with other commonly used molecular typing methods. The presence of the 11 known SAg genes and two other exotoxin-encoding genes (speB and speF) was tested in a collection of 480 clinical GAS isolates, using two multiplex PCR reactions. The SAg gene profile was compared with other typing methods. Four naturally occurring deletions involving the genes speB, speF, and rgg were characterized, two of which were found among invasive isolates. The absence of the chromosomally encoded genes speG and smeZ was supported by Southern blot hybridization and associated with specific GAS lineages, while the presence of phage-encoded genes was more variable. Positive associations between SAg genes or between SAg profiles and emm types or pulsed-field gel electrophoresis (PFGE) clusters were observed. The results suggest that the SAg profile diversifies faster than other properties commonly used for molecular typing, such as emm type and multilocus sequence typing (MLST) sequence types (STs), and can be a useful complement in GAS molecular epidemiology. Still, the short-term stability of the SAg gene profile among prevalent genetic lineages may largely explain the observed associations between SAg genes.
