Development of the Multiple Sclerosis Resiliency Scale (MSRS)

Objectives: While resilience has been an area of increasing research, there are no measures that are specific to the psychological, social, and physical factors associated with resilience in persons with multiple sclerosis (PwMS). This study aimed to develop the MS Resiliency Scale (MSRS), a multidimensional measure. Items were created based on a review of the literature, with five hypothesized subscales, and then evaluated in a large sample of PwMS. Method: Participants (N = 932) were primarily recruited through the North American Research Committee on MS (NARCOMS) and completed the study electronically. Principal components analysis was utilized to determine the number of factors and whether they aligned with the theorized model. Results: Using an unforced solution with oblique (promax) rotation and Kaiser normalization, and suppressing items with coefficients below 0.4, 25 items were retained in five subscales that accounted for 42.75% of the variance: Emotional and Cognitive Strategies (13 items; &agr; = .92), Physical Activity and Diet (3 items; &agr; = .77), MS Peer Support (2 items; &agr; = .82), Support from Family and Friends (5 items; &agr; = .79), and Spirituality (2 items; &agr; = .91). The total score was negatively correlated with depression, r = −. 72, p < . 001 and anxiety, r = −. 56, p < . 001. Implications: The 25-item MSRS assesses several psychological, social, and physical factors associated with resilience in PwMS, and may be a helpful tool in identifying individuals in need of additional assistance or support.
Diagnosis and follow-up of patients with Hunter syndrome in Spain

Abstract Hunter syndrome or mucopolysaccharidosis type II (MPSII) is a progressive multisystem X-linked lysosomal storage disease caused by mutations in the IDS gene that shows a wide spectrum of clinical symptoms and severity. Idursulfase, a specific enzyme replacement therapy (ERT) for MPSII, has been available since 2007. ERT, along with symptomatic management of patients, is fundamental for improving patient prognosis and quality of life. The aims of this study were to investigate whether Spanish pediatricians who are experts in managing the disease agreed with current international guidelines regarding MPSII patient diagnosis and follow-up; and to reach a consensus regarding which items are essential for the diagnosis, follow-up, and treatment of these patients in Spain. An advisory panel of 5 experts from the Hunter Spanish Working Group reviewed key studies, developed a questionnaire based on a modified Delphi method, sent the questionnaire to selected experts, and reviewed the responses. The final questionnaire had 83 items in the following categories: diagnosis, ERT considerations after diagnosis, Periodic assessments, and ERT considerations during follow-up. A total of 85 experts were invited to participate; 28 (35%) responded and showed a strong consensus for most items. The advisory panel decided not to perform a second Delphi round. There was strong agreement (>3.1 median value; range, 1 to 4) for 43/56 items in Diagnosis, for 4/6 items in “ERT considerations after diagnosis,” for 6/16 items in “Periodic assessments,” and for 3/5 items in “ERT considerations during follow-up. ” Most responses were in agreement with international guidelines, and controversial items were discussed by the advisory panel. Based on the results, on the key studies, and on clinical experience and opinions, the panel developed and scheduled recommendations for the diagnosis and follow-up of patients with MPSII. An expert 5-person panel oversaw a Delphi survey of 28 pediatricians and reached a consensus on recommendations for the diagnosis and follow-up of MPSII patients. This document will help guide clinicians involved in the diagnosis, management, and treatment of MPSII.
Prognostic Value of a Simple Echocardiographic Parameter, the Right Ventricular Systolic to Diastolic Duration Ratio, in Patients with Advanced Heart Failure with Non-Ischemic Dilated Cardiomyopathy.

The prognostic value of the right ventricular (RV) systolic to diastolic duration ratio (S/D ratio) in patients with advanced heart failure is not clear.We enrolled 45 patients with DCM (40 ± 13 years, 33 male) who were admitted to our hospital for evaluation or treatment of heart failure. The RV systolic and diastolic durations were measured using continuous Doppler imaging of tricuspid regurgitation, and the RV S/D ratio was calculated. Cardiac events were defined as cardiac death or left ventricular assist device implantation within the first year. Twenty-eight cardiac events occurred. The RV S/D ratio was significantly higher in the event group than in the event-free group (1.8 ± 0.8 versus 1.2 ± 0.5, P = 0.008). Univariate analysis showed that the RV S/D ratio, plasma brain natriuretic peptide concentration, left atrial volume index, and mitral deceleration time were associated with these events. Receiver operating characteristic curve analysis revealed that the optimal RV S/D cutoff value to predict events was 1.2 (sensitivity 79%, specificity 65%, area under the curve 0.745). Kaplan-Meier analysis indicated a significantly higher event rate in patients with an RV S/D ratio > 1.2 (log-rank test, P = 0.003). The addition of an RV S/D ratio > 1.2 improved the prognostic utility of a model that included conventional variables (P = 0.014). In patients with advanced heart failure with DCM, the RV S/D ratio was higher in patients with events than in those without events. The addition of the RV S/D ratio to conventional parameters may provide better prognostic information.
Microstructure and Corrosion Behavior of Composite Coating on Pure Mg Acquired by Sliding Friction Treatment and Micro-Arc Oxidation

For the purpose of detecting the influence of grain structure of a Mg matrix on the microstructure and corrosion resistance of micro-arc oxidation (MAO) coating, prior to MAO processing, sliding friction treatment (SFT) was adopted to generate a fine-grained (FG) layer on coarse-grained (CG) pure Mg surface. It showed that the FG layer had superior corrosion resistance, as compared to the CG matrix, owing to the grain refinement; furthermore, it successfully survived after MAO treatment. Thus, an excellent FG-MAO coating was gained by combining SFT and MAO. The surface morphology and element composition of FG-MAO and CG-MAO samples did not show significant changes. However, the FG layer favorably facilitated the formation of an excellent MAO coating, which possessed a superior bonding property and greater thickness. Consequently, the modified FG-MAO sample possessed enhanced corrosion resistance, since a lower hydrogen evolution rate, a larger impedance modulus and a lower corrosion current were observed on the FG-MAO sample.
Bioactive Sesquiterpenoids from the Peeled Stems of Syringa pinnatifolia.

Fourteen new sesquiterpenoids, alashanoids A-H (1, 2, and 4-9), (+)-2,9-humuladien-6-ol-8-one (3b), and five pairs of enantiomers (1 and 4-7), along with eight known analogues (3a and 10-16) were isolated from the stems of Syringa pinnatifolia. The structures were established using IR, UV, MS, and NMR data. The absolute configurations of the new compounds were resolved by X-ray diffraction, a modification of Mosher's method, and experimental and calculated ECD data analysis. The new sesquiterpenoids represent three skeletons: a rare 2,2,5,9-tetramethylbicyclo[6.3. 0]-undecane (1), a humulane-type (2-8), and a caryophyllene-type (9) skeleton. Compounds 6a, 7, and 11 showed protective effects against hypoxia-induced injury to H9c2 cells at a concentration of 40 μM, and 5-7, 11, and 13 inhibited NO production in LPS-induced RAW264.7 macrophage cells with IC50 values ranging from 13.6 to 70.6 μM. These compounds decreased the TNF-α and IL-6 levels in RAW264.7 cells in a concentration-dependent manner at 20-80 μM.

Lenvatinib for Anaplastic Thyroid Cancer and Lenvatinib-Induced Thyroid Dysfunction

Background: Lenvatinib is an oral multitargeted tyrosine kinase inhibitor that has an anticancer action in patients with differentiated thyroid cancer that is refractory to radioiodine. Knowledge of the efficacy and safety of lenvatinib in patients with anaplastic thyroid cancer (ATC) is limited. Tyrosine kinase inhibitors frequently cause hypothyroidism, but the incidence of hypothyroidism with lenvatinib is unclear. Objectives: We conducted a retrospective study to investigate the efficacy and safety of lenvatinib in ATC. Methods: Five patients with unresectable ATC were enrolled. Lenvatinib 24 mg once daily was administered until disease progression, unmanageable toxicity, withdrawal, or death occurred. We retrospectively analyzed the objective response rate (ORR), time to progression (TTP), overall survival, and safety. Results: Three of the 5 patients (60%) had a partial response, and 5 (40%) had stable disease. The ORR was 60%. Median TTP was 88 days, and overall survival was 165 days. Hypothyroidism was a common treatment-related adverse effect; 4 patients (80%) had hypothyroidism of any grade. These 4 patients had not undergone total thyroidectomy prior to lenvatinib administration, and the other patient had undergone total thyroidectomy. Treatment-related adverse effects of any grade were hypertension in 80% of patients, diarrhea in 40%, fatigue in 80%, and decreased appetite in 80%. Conclusions: Lenvatinib is an effective treatment and may improve the prognosis of unresectable ATC. Four of the 5 patients had hypothyroidism, which may have been associated with treatment-induced injury of the thyroid gland. There were many treatment-related adverse effects, most of which were manageable by dose modification and medical therapy.
Substance Use Patterns of Gay and Bisexual Men in the Momentum Health Study

Research with male sexual minorities frequently combines gay and bisexual men as Men Who Have Sex with Men or Gay and Bisexual Men. When analyzed separately, bisexual men consistently feature negative health differentials, exemplified by higher substance use levels. This interpretation is not clear-cut because studies may combine bisexual men and women, use different dimensions of sexual orientation to define bisexuality, and/or not consider number of sexual partners as a possible confounding factor. This study conducted separate bivariate and multivariate analyses comparing gay to bisexual Momentum Study participants based on self-identity, sexual attraction, and sexual behavior, while controlling for number of sexual partners and sociodemographic, psychosocial, and sexual behavior measures. The study hypothesized that, regardless of definition, bisexual men feature higher substance use levels compared to gay men. Bivariate analyses revealed significantly higher (p < .05) use among bisexual men for multiple substances in all samples. Nonprescription stimulants and heroin were significant in all multivariate logistic regression models. In contrast, all bisexual samples reported lower use of erectile dysfunction drugs and poppers, substances associated with anal sex among gay men. Subsequent analysis linked these results to lower levels of anal sex in all bisexual samples. Bivariate analyses also revealed that bisexual men featured significantly lower educational levels, annual incomes, and Social Support Scales scores and higher Anxiety and Depression Sub-Scale Scores. In summary, findings revealed bisexual men’s distinctive substance use, sexual behavior, psychosocial, and sociodemographic profiles, and are important for tailoring specific health programs for bisexual men.
Chlorhexidine–alcohol versus povidone–iodine for skin preparation before elective cesarean section: a prospective observational study

Abstract Introduction: The ideal antiseptic agent for skin preparation before elective cesarean section (CS) is not yet determined. The aim of the study was to assess the impact of skin preparation by chlorhexidine–alcohol compared with povidone–iodine before elective CS on the rate of surgical site infection (SSI). Materials and methods: This prospective observational study included a total of 1424 pregnant women at term who were candidates for the elective CS and were divided into two equal groups of 712 patients in each, group 1 (chlorhexidine–alcohol group) and group 2 (povidone–iodine group). Patients were followed up at 1 week and 1 month postoperative to determine the rate of SSI. Results: The rate of SSI was 3.7% (26 patients) in the chlorhexidine–alcohol group compared with 4.6% (33 patients) in the povidone–iodine group (odds ratio: 0.7798, 95% CI: 0.46–1.3, p = .35), nine patients in the chlorhexidine–alcohol group, and 10 patients in the povidone–iodine group required resuturing (odds ratio: 0.9, 95% CI: 0.36–2.2, p = .82). Four patients (0.56%) in the chlorhexidine–alcohol group and five patients (0.7%) in the povidone–iodine group developed endometritis (p = .74). The rate or readmission because of SSI was 2.7% (19 patients) in the chlorhexidine–alcohol group and 2.9% (21 patients) in the povidone–iodine group (p = .75). Conclusions: Skin preparation with either chlorhexidine–alcohol or povidone–iodine resulted in comparable rates of SSIs. Accordingly, both are suitable antiseptic agents for skin preparation before elective CS.
Alteration to hippocampal volume and shape confined to cannabis dependence: a multi‐site study

Cannabis use is highly prevalent and often considered to be relatively harmless. Nonetheless, a subset of regular cannabis users may develop dependence, experiencing poorer quality of life and greater mental health problems relative to non‐dependent users. The neuroanatomy characterizing cannabis use versus dependence is poorly understood. We aimed to delineate the contributing role of cannabis use and dependence on morphology of the hippocampus, one of the most consistently altered brain regions in cannabis users, in a large multi‐site dataset aggregated across four research sites. We compared hippocampal volume and vertex‐level hippocampal shape differences (1) between 121 non‐using controls and 140 cannabis users; (2) between 106 controls, 50 non‐dependent users and 70 dependent users; and (3) between a subset of 41 controls, 41 non‐dependent users and 41 dependent users, matched on sample characteristics and cannabis use pattern (onset age and dosage). Cannabis users did not differ from controls in hippocampal volume or shape. However, cannabis‐dependent users had significantly smaller right and left hippocampi relative to controls and non‐dependent users, irrespective of cannabis dosage. Shape analysis indicated localized deflations in the superior‐medial body of the hippocampus. Our findings support neuroscientific theories postulating dependence‐specific neuroadaptations in cannabis users. Future efforts should uncover the neurobiological risk and liabilities separating dependent and non‐dependent use of cannabis.
Psychometric Properties of the Spanish Adaptation of the Personality Assessment Inventory in Correctional Settings: An ESEM Study

Abstract The Personality Assessment Inventory (PAI; Morey, 1991, 2007) is among the most important personality and psychopathology assessment tools. However, its psychometric properties in the Spanish-speaking prison population have not yet been studied. We aimed to explore the factor structure of the Spanish adaptation of the PAI (Ortiz-Tallo et al., 2011) in an Ecuadorian sample of 811 convicted men using exploratory structural equation modeling, with the further objective of confirming its internal consistency. Hoelzle and Meyer (2009) identified three dimensions that are highly congruent across samples: general distress, elevated mood and dominance, and substance abuse and psychopathy. Taking these findings and the internalizing and externalizing dimensions (Ruiz & Edens, 2008) as a theoretical basis, three- and two-factor models were tested for the 22 scales and 11 clinical scales, respectively. We also tested four- and three-factor models that grouped the scales related to substance abuse as an independent factor, leaving intact the distribution presented by the remaining scales in the previous models. Although the original models showed a good fit, the 4- and 3-factor models obtained significantly better fit indexes. With respect to reliability, the Cronbach’s alpha coefficients ranged from . 49 to . 89. This version shows acceptable psychometric properties in correctional settings.
Out‐of‐hospital arrests attending an Australian tertiary paediatric emergency department over 13 years: An observational study

In paediatric cardiopulmonary arrest, International Liaison Committee on Resuscitation (ILCOR) states, ‘there are no simple guidelines to determine when resuscitative efforts become futile’. Considerations to assist this decision‐making include cause of arrest, pre‐existing medical conditions, age, site of arrest, duration of untreated cardiopulmonary arrest, witnessed arrest and presence of shockable rhythm. Outcomes are poor in out‐of‐hospital cardiac arrests (OHCA), particularly for infants. This single‐centre observational study describes the characteristics and outcomes of the subgroup of children presenting to our hospital's ED following OHCA still receiving cardiac compressions, to assist development of guidelines for future resuscitation efforts in our ED, particularly for cessation of cardiopulmonary resuscitation (CPR).
Immunohistochemical expression of hormone receptors, Ki-67, endoglin (CD105), claudins 3 and 4, MMP-2 and -9 in endometrial polyps and endometrial cancer type I

Objective The aim of this study was to investigate the malignant potential of endometrial polyps (EP) by assessing the immunoexpressions of both estrogen receptor (ER) and progesterone receptor (PR), Ki-67 cell proliferation index, neovascularization network (endoglin – CD105), cellular adhesion molecules (claudins 3 and 4), and extracellular matrix proteins (MMP-2 and -9) in both EP and endometrioid adenocarcinoma (type I) in comparison with the normal endometrium. Study design This is a cross-sectional comparative study. Patients were identified from the database of Botucatu Medical School, São Paulo State University (BMS-UNESP) Clinical Pathology Laboratory. Setting The study was conducted using a convenience sample of patients attending the Sectors of Gynecologic Endoscopy and Family Planning and Gynecologic Oncology of the Department of Gynecology and Obstetrics of BMS-UNESP, Brazil. Patients A total of 90 women were allocated into the following three groups: EP without atypia (EP, n=30), endometrioid endometrial cancer (EC, n=30), and normal endometrium (control, n=30). Methods Epidemiological and clinical data were obtained by reviewing medical records. Adenocarcinoma and control cases were assessed using the tissue microarray technique. The immunoexpressions of ER, PR, Ki-67, CD105, claudins 3 and 4, and MMP-2 and -9 were assessed in paraffin blocks containing sections of the largest polyploid lesion fragment and tissue microarray recipient blocks. Major results Compared to the control group, significant differences in the expression of ER (P<0.001), PR (P<0.05), Ki-67 (P<0.001), CD105 (P<0.001), and claudin 3 (P<0.001) were observed in EP and EC. No significant differences were found between EP and EC (P≥0.05). MMP-2 and -9 expression were nearly absent in all groups. Conclusion The malignant potential of EP could not be determined through the immunohistochemical parameters used in this study. No MMP-2 or -9 expression was observed in any endometrial tissue sample. Further studies are necessary for a better understanding of the biomolecular mechanisms underlying endometrial carcinogenesis.
Bethesda Classification and Cytohistological Correlation of Thyroid Nodules in a Brazilian Thyroid Disease Center

Background: The Bethesda System has been used to classify thyroid cytology in 6 categories besides presenting malignancy rates and respective approaches. Reference centers have validated its use by comparing its proposed malignancy rates with those in in their populations. However, to the best of our knowledge, there has been no corresponding study in Brazil. Objectives: To evaluate the performance of the Bethesda classification in a Brazilian thyroid reference center and correlate the results with cytohistological reports in patients referred to surgery. Methods: Data records from 980 fine-needle aspiration (FNA) results were retrospectively analyzed, and, in patients who underwent surgery, the results were correlated with the cytohistological findings. Results: 980 FNAs and 585 patients were evaluated. The incidence of each cytological category was: 11% nondiagnostic (ND), 59.6% benign, 7.1% (atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS), 8.5% follicular neoplasm or suspicious for follicular neoplasm (FN/SFN), 5.1% suspicious for malignancy (SM), and 8.3% malignant. The surgery rate was 41.8% (245/585). The malignancy rate in each category was: 6% benign, 12% AUS/FLUS, 20.8% FN/SFN, 72.5% SM, and 97.3% malignant. For ND nodules, the malignancy rate was 25.7% (66.6% multifocal and papillary microcarcinomas), a higher rate than in the literature. In this category, surgery was performed in multinodular goiters presenting with another nodule > 3.0 cm and/or with an FN/SFN, SM, or malignant cytological result. Conclusion: The Bethesda System can be applied to the Brazilian population, since the frequency and malignancy rates of each category were similar to those described by its classification. It is noteworthy that a higher risk of malignancy was observed in the ND cytological category.
