Nocturnal paroxysmal arousals with motor behaviors during sleep: frontal lobe epilepsy or parasomnia?

Nocturnal paroxysmal arousals with motor behaviors have been described in a few individuals, and their possible epileptic origin as nocturnal frontal lobe seizures has been suggested. However, the clinical and polysomnographic differentiation from parasomnias and physiologic movements during sleep have not been clarified yet. In this study, we evaluated a group of patients with nocturnal motor behaviors and tried to characterize paroxysmal arousals. Thirty-four participants (mean [+/-SD] age 22.7 [+/-12.9] years) noting nocturnal motor agitation or behaviors and 12 healthy controls (mean age 24.1 [+/-3.1] years) underwent nocturnal polysomnography with video-tape recording and motor behaviors analysis. Arousals with motor attacks were classified as minimal, minor, or major depending on semiology, complexity, and duration of behaviors. All patients showed several minimal (e.g., scratching or rubbing the nose and the head) and minor (e.g., pelvic thrusting or swinging with dystonic component) attacks, and 53% also had major episodes (e.g., sudden elevation of the head and trunk from the bed with complex behaviors) occurring mainly in non-rapid eye movement sleep. In all the patients, motor attacks were characterized by stereotypy, sudden onset, short duration, and repetitiveness. In 80%, epileptiform abnormalities were found. All control subjects showed motor events, but they were fewer, slower, nonstereotyped, and semiologically different from the patients'. No significant difference in conventional sleep parameters between the two groups were found. Paroxysmal arousals with motor behaviors probably represent a particular form of nocturnal frontal lobe epilepsy rather than an unusual parasomnia. The semiologic characteristics of these type of arousals are difficult to recognize and differentiate from physiologic movements or parasomnias without video-polygraphic analysis.
Effects of Tadalafil on Hemorrhagic Cystitis and Testicular Dysfunction Induced by Cyclophosphamide in Rats

Introduction: The protective and/or therapeutic potential of tadalafil (TDL) on cyclophosphamide (CP)-induced hemorrhagic cystitis (HC) and testicular dysfunction in rats was evaluated. Materials and Methods: The animals except from the control group were divided into four groups and treated with saline, or 1, 5 or 10 mg/kg TDL orally (CP, TDL1, TDL5 and TDL10 groups, respectively) before and after CP injection. Body and organ weights, sperm count, cGMP, nitric oxide (NO), IL-6 and IL-10 levels in serum and bladder tissue, and serum testosterone (T), LH and FSH levels were determined. The histological analysis of bladder and testis was performed and the number of apoptotic cells was determined. Results and Conclusion: The CP group had decreased cGMP and NO levels in the bladder, serum T level (p < 0.05) and sperm count (p < 0.001) and higher IL-6 levels in serum and bladder (p < 0.01). Treatment with TDL resulted in increased cGMP (p < 0.001), NO (p < 0.05) and serum T (p < 0.05) levels. Histological analysis of the CP group showed severe HC in bladder and testicular damage. TDL-treated animals showed a dose-dependent improvement in all of these histological impairments. In conclusion, a selective inhibitor of phosphodiesterase-5 enzyme, TDL, showed a protective and/or therapeutic effect on CP-induced HC and testicular dysfunction in rats.
Associations between ADHD symptoms and smoking outcome expectancies in a non-clinical sample of daily cigarette smokers.

BACKGROUND AND OBJECTIVES Smoking outcome expectancies for positive reinforcement (PR: beliefs that smoking produces desirable outcomes) and negative reinforcement (NR: beliefs that smoking alleviates negative affect) are modifiable cognitive manifestations of affect-mediated smoking motivation. Based on prior data and theory, we hypothesized that NR and PR expectancies are associated with ADHD symptom levels in a non-clinical sample of cigarette smokers. (Am J Addict 2016; XX:XX -XX) METHODS: Daily cigarette smokers (N = 256) completed self-report measures of ADHD symptoms and smoking outcome expectancies. Cross-sectional associations of overall ADHD symptomatology and the ADHD symptom dimensions of inattention (IN: difficulty concentrating and distractibility) and hyperactivity impulsivity (HI: poor inhibitory control and motor activity restlessness) with PR and NR smoking outcome expectancies were examined. RESULTS Higher levels of overall, IN and HI ADHD symptoms were positively associated with NR smoking expectancies after statistically controlling for anxiety, depression, alcohol/drug use problems, nicotine dependence, and other smoking expectancies. Although neither HI nor IN symptom dimensions exhibited empirically unique relations to NR expectancies over and above one another, the collective variance across IN and HI was associated with NR expectancies. PR expectancies were not associated with ADHD symptoms. DISCUSSION AND CONCLUSIONS Although PR and NR expectancies may be important etiological influences in the overall population of smokers, NR outcome expectancies appear to be disproportionately expressed in smokers with elevated ADHD symptoms. Cognitive manifestations of NR motivation, which may be modifiable via intervention, are prominent in smokers with elevated ADHD symptoms. SCIENTIFIC SIGNIFICANCE Beliefs that smoking alleviates negative affect may underlie ADHD-smoking comorbidity.
To share or not to share knowledge: Observing the factors

Due to the changing business environment, organizations are facing challenges of global competitiveness. Sharing knowledge is an important aspect of most modern organization. University governance is not immune from the impacts of this environmental fluctuation. Universities are creators of new knowledge through research and education but it should not be forgotten that Universities are organizations which will need to utilize knowledge to develop competitive advantage as any other business entity would need to do. This study examines the factors influencing knowledge sharing behavior amongst academicians, taking Universiti Teknologi Mara (UiTM), Kedah as a sample. The factors influencing knowledge sharing behavior include motivation to share knowledge, management support, information technological literacy and teamwork spirit. The result of correlation showed that there is a positive relationship on teamwork spirit and management support toward knowledge sharing behavior amongst academicians.
Serum Ratio of Heart-Type Fatty Acid-Binding Protein to Myoglobin

Background: The concentration of heart-type fatty acid-binding protein (hFABP), a promising novel marker for detection of acute or persistent myocardial damage, is significantly influenced by renal clearance and thus has limitations to its usefulness in patients with renal dysfunction. We evaluated whether the serum ratio of hFABP to myoglobin (F/M) might be a useful marker for assessing cardiac damage in hemodialysis patients. Methods: Serum hFABP and myoglobin were measured, and the value of F/M was calculated in 21 hemodialysis patients. Cardiac markers (cardiac troponin T [cTnT], atrial natriuretic peptide [ANP], and brain natriuretic peptide [BNP]) and echocardiographic indices (left ventricular end-diastolic dimension [LVDd], left ventricular mass index [LVMI], and inferior vena cava [IVC] dimension) were examined and compared with hFABP, myoglobin, and F/M ratios. Results: Serum hFABP and myoglobin levels were significantly elevated in hemodialysis patients and reduced by 30–40% during hemodialysis. The value of F/M after hemodialysis, but not the concentration of hFABP or myoglobin, had significant linear correlations with ANP, BNP, cTnT, LVDd, LVMI, and IVC. Conclusion: The value of F/M after hemodialysis, but not the concentration of hFABP itself, might be a newly useful marker for estimation of cardiac damage and volume overload in hemodialysis patients.
Detention of Elderly Psychiatric Inpatients under Section 5(2) of the Mental Health Act 1983

Emergency detention of elderly psychiatric inpatients appears to have attracted very little or no attention in published studies. In this retrospective review, all applications of sections 5(2) and 5(4) of the Mental Health Act 1983, detaining elderly inpatients in North Cheshire between 1985 and 1997 were reviewed. Forty-three percent of elderly inpatients under s.5(2) regained their voluntary status, while 57% were detained under another section by the end of the 72 hours (p<0.05). Duration in hospital prior to applying s.5(2), clinical diagnosis of functional mental illness and use of s.5(4) appear to increase the likelihood of converting s.5(2) into other sections. The high rate of non-conversion of s.5(2) in the elderly to s.2 or 3 may imply that in almost half of the cases, emergency detention may have been used to control isolated incidents of disturbed behaviour in otherwise co-operative patients. Educating doctors and nurses in guidance put forward by the Code of Practice (1993) remains, probably, the main key to a better use of emergency holding powers.
High Activity Suppression of Myeloid Progenitor Proliferation by Chimeric Mutants of Interleukin 8 and Platelet Factor 4 (*)

The proliferation of human myeloid progenitor cells is negatively regulated in the presence of certain members of the chemokine family of molecules. This includes interleukin 8 (IL-8) and platelet factor 4 (PF4), which in combination are able to synergize, resulting in cell suppression at very low concentrations of these molecules. A series of PF4 and IL-8 mutant proteins were analyzed in an in vitro colony formation assay for myeloid progenitor cells to assess domains of these proteins that are required for activity. Mutation of either of the two DLQ motifs within PF4 resulted in an inactive protein. Perturbations within the IL-8 dimer interface region also resulted in mutants that were incapable of suppressing colony formation. A class of chimeric mutants consisting of domains of either PF4 and IL-8, Gro-α and PF4, or Gro-β and PF4 were observed to inhibit myeloid cell proliferation at concentrations which were between 500- and 5000-fold lower than either the IL-8 or PF4 wild-type proteins alone. These chimeric mutants possessed activities that were comparable to or better than the activity observed when IL-8 and PF4 were added together in vitro. One of these highly active chimeric proteins was observed to be 1000-fold more active than either IL-8 or PF4 alone in suppressing not only the proliferation but also the cell cycling of myeloid progenitor cells following intravenous injection of the mutant into mice. Examination of additional IL-8-based mutants in the colony formation assay, which centered on the perturbation of the amino-terminal “ELR” motif, resulted in the observation that the highly active IL-8 mutant required both aspartic acid at amino acid residue 4 and either glutamine or asparagine at residue 6. Single mutations at either of these positions resulted in mutants with myelosuppressive activity equivalent to wild-type IL-8. Mutants such as IL-8M1 and IL-8M10 were observed to be significantly reduced in their ability to activate isolated human neutrophils, suggesting that separate mechanisms may exist by which myeloid progenitor cells and neutrophils are affected by chemokines.
Effects of intense pulsed light and ultraviolet A on metalloproteinases and extracellular matrix expression in human skin.

OBJECTIVE The aim of this study was to evaluate the effects of intense pulsed light (IPL) and ultraviolet A (UVA) irradiation on the expression of matrix metalloproteases (MMPs), tissue inhibitor of metalloproteinase 1 (TIMP-1), and extracellular matrix (ECM) in human skin, and to confirm the relative mechanism. BACKGROUND DATA IPL has been widely used to treat photoaged skin but the underlying mechanism remains unknown. METHODS Human buttock skin was irradiated by repetitive suberythemal doses of UVA and therapeutic doses of IPL. Skin biopsies were taken and the protein/mRNA expression of MMP-1, -3, -9, and -12 and TIMP-1 was examined by immunohistochemistry, image analysis, and real-time quantitative polymerase chain reaction (qRT-PCR). RESULTS Compared with normal control skin, both IPL and UVA irradiation induced a general elevation of MMP-1, -3, -9, and -12 and TIMP-1 at protein/mRNA levels, with some differences in the MMP expression patterns, e.g., a remarkable increase of MMP-1, -3, and -12 in UVA-exposed skin, while lower MMP-1, -3, and -12 (p < 0.01, p < 0.01, p < 0.01) but higher MMP-9 (p < 0.05) levels in IPL-irradiated skin. Meanwhile, increased collagen I fibers (p < 0.05) were observed in IPL-irradiated skin, whereas fragments of elastic fibers were found in UVA-exposed skin. CONCLUSION These findings demonstrated that IPL has similar effects on the expression of MMPs/TIMP-1 in human skin to UVA, but the expression pattern differed from that in UVA-exposed skin, which may account for IPL's photorejuvenation effects.
High Flow Nasal Cannulae versus Nasal Continuous Positive Airway Pressure in Neonates with Respiratory Distress Syndrome Managed with INSURE Method: A Randomized Clinical Trial

Background: In recent years, various noninvasive respiratory support (NRS) of ventilation has been provided more in neonates. The aim of this study was to compare the effect of HFNC with NCPAP in post-extubation of preterm infants with RDS after INSURE method (intubation, surfactant, extubation). Methods: A total of 54 preterm infants with RDS (respiratory distress syndrome) were enrolled in this study. Using a randomized sequence, they were assigned into two groups after INSURE method. The first group received HFNC while the second group received NCPAP for respiratory support after extubation. A comparison was made between these two groups by the rate of reintubation, air leak syndrome, duration of oxygen therapy, hospitalization, the rate of bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), retinopathy of prematurity (ROP), and mortality. Data were analyzed by using the SPSS version 18 software. The statistical analyses included Student’s t-test for continuous data and compared proportions using Chi-squared test and Fisher‘s exact test for categorical data. Result: The rate of reintubation was higher in the HFNC compared with the NCPAP group. The rate of either IVH or ROP had no significant differences between the two groups. In addition, duration of oxygen requirement and hospitalization were not statistically different. There was no case of BPD or mortality among these patients. Conclusion: This study showed that preterm infants with RDS could manage post-extubation after INSURE method with either NCPAP or HFNC. However, in this single-center study, the rate of reintubation was higher in the HFNC group while further multicenter study might be assigned. Trial Registration Number: IRCT201201228800N1
Analysis and Optimization of a Device Intended to Reproduce a Magnetic Field Along a Path

The paper shows a generalization and further development of a previous work of ours already published. We describe and analyze a kind of devices intended to create a prescribed magnetic field using a set of conductors. More precisely, we discuss a device that is capable of shaping the tangential component of the magnetic field along a specific path by controlling the current applied to each conductor. An orthogonal function decomposition is used to determine the magnitude of each current. The system performance depends on the number of conductors and their location, so we introduce a set of quality parameters, and some common geometries are evaluated upon them. These devices are intended for calibration purposes of current measuring instruments based on Ampere's integral, although the metrological aspects are out of the scope of this paper.
Has child marriage declined in sub-Saharan Africa? An analysis of trends in 31 countries.

Age at marriage is rising throughout sub-Saharan Africa. The singulate mean age at marriage is now greater than 18 in the vast majority of countries in the region and in all of the countries included in our analysis (United Nations Department of Economic and Social Affairs Population Division 2015). Even so sub-Saharan Africa has the highest rates of child marriage in the world and previous studies have estimated that more than half of girls marry before age 18 in many countries in the region (Singh and Samara 1996; Mensch Singh and Casterline 2006). Measuring trends in the prevalence of child marriage over time is important for understanding where the practice is most common and for evaluating the effectiveness of efforts to eliminate it. However measuring age at marriage in sub-Saharan Africa is difficult. Unlike Western marriages which are often unambiguously dated by a ceremony the signing of legal documents and civil registration marriage in sub-Saharan Africa is often described as a process consisting of multiple stages including legitimized sexual relations cohabitation and ceremonies. The process can be lengthy and the various stages occur in different sequences across ethnic and social groups (van de Walle and Meekers 1994; Locoh 1994; Arnaldo 2004). If several events are required to solidify a union it may be unclear when the union was formalized. (excerpt)
Major types of dietary fat and risk of coronary heart disease: a pooled analysis of 11 cohort studies.

BACKGROUND Saturated fatty acid (SFA) intake increases plasma LDL-cholesterol concentrations; therefore, intake should be reduced to prevent coronary heart disease (CHD). Lower habitual intakes of SFAs, however, require substitution of other macronutrients to maintain energy balance. OBJECTIVE We investigated associations between energy intake from monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), and carbohydrates and risk of CHD while assessing the potential effect-modifying role of sex and age. Using substitution models, our aim was to clarify whether energy from unsaturated fatty acids or carbohydrates should replace energy from SFAs to prevent CHD. DESIGN This was a follow-up study in which data from 11 American and European cohort studies were pooled. The outcome measure was incident CHD. RESULTS During 4-10 y of follow-up, 5249 coronary events and 2155 coronary deaths occurred among 344,696 persons. For a 5% lower energy intake from SFAs and a concomitant higher energy intake from PUFAs, there was a significant inverse association between PUFAs and risk of coronary events (hazard ratio: 0.87; 95% CI: 0.77, 0.97); the hazard ratio for coronary deaths was 0.74 (95% CI: 0.61, 0.89). For a 5% lower energy intake from SFAs and a concomitant higher energy intake from carbohydrates, there was a modest significant direct association between carbohydrates and coronary events (hazard ratio: 1.07; 95% CI: 1.01, 1.14); the hazard ratio for coronary deaths was 0.96 (95% CI: 0.82, 1.13). MUFA intake was not associated with CHD. No effect modification by sex or age was found. CONCLUSION The associations suggest that replacing SFAs with PUFAs rather than MUFAs or carbohydrates prevents CHD over a wide range of intakes.
The effect of multi-wall carbon nanotubes on electromagnetic interference shielding of ceramic composites

Multi-wall carbon nanotubes (MWCNTs)–3 mol% yttria-stabilized zirconia (3Y-TZP) (MWCNTs-3Y-TZP) composite was prepared by spark plasma sintering. The complex permittivities of the composite have been measured in the Ku-band range (12.4–18 GHz) and it is found that both the real and imaginary permittivities of the composite increase with the increasing content of MWCNTs. The effect of the content of MWCNTs on the electromagnetic interference (EMI) shielding effectiveness (SE) of the composite has been evaluated, and it is found that the EMI SE of the composite increases with the increasing content of MWCNTs. An EMI SE value as high as 25–30 dB has been achieved in the Ku-band range for the composite with 9 wt% content of MWCNTs, indicating that the MWCNTs-3Y-TZP composite can be used as an effective EMI shielding material.
Anti-dsDNA and anti-Sm antibodies do not predict damage in systemic lupus erythematosus

We aimed to determine whether anti-dsDNA and anti-Sm antibodies predict damage in systemic lupus erythematosus (SLE). Five-hundred inception patients from the University of Toronto Lupus Clinic were studied. Predictors assessed for the entire study period were: 1) raised anti-dsDNA on two consecutive occasions; 2) anti-dsDNA levels (normal, mildly or highly elevated); 3) presence of anti-Sm on any occasion. To account for disease duration, the following were assessed at three years post-inception: raised anti-dsDNA on two consecutive occasions; anti-dsDNA levels. These predictors were correlated with the following outcomes: 1) overall SLICC/ACR Damage Index (SDI) at the end of the study period; 2) frequency of damage in the cardiovascular, neuropsychiatric, musculoskeletal and renal components of SDI; 3) SDI at five years for the predictors assessed at three years post-inception. In the multivariate analysis, presence of anti-DNA antibodies or of anti-SM were non-significant but sex, age at SLE diagnosis, disease duration, corticosteroid use and cumulative dose were strong predictors of damage. Raised anti-dsDNA on two occasions or anti-dsDNA levels in the three years post-inception patients did not predict damage at five years. The presence and levels of anti-dsDNA and anti-Sm antibodies do not predict damage in SLE.
Two new insecticidal sesquiterpene esters from Euonymus japonicus

Two new insecticidal sesquiterpene esters with a β-dihydroagarofuran sesquiterpene skeleton, ejaponine A (1) and ejaponine B (2), and two known compounds, 3 and 4, were isolated from the EtOAc extract of the root bark of Euonymus japonicus Thunb. by bioassay-guided fractionation. Their chemical structures were elucidated mainly by analysis of MS and NMR spectral data. The LD50 values of ejaponine A (1), ejaponine B (2), 3 and 4 showed against Mythimna separata were 89.2, 98.6, 181.4 and 109.2 µg g−1, respectively.
Impact of Early Parental Child-Rearing Behavior on Young Adults’ Cardiometabolic Risk Profile: A Prospective Study

Objective: To examine prospectively whether early parental child-rearing behavior is a predictor of cardiometabolic outcome in young adulthood when other potential risk factors are controlled. Metabolic factors associated with increased risk for cardiovascular disease have been found to vary, depending on lifestyle as well as genetic predisposition. Moreover, there is evidence suggesting that environmental conditions, such as stress in pre- and postnatal life, may have a sustained impact on an individual’s metabolic risk profile. Methods: Participants were drawn from a prospective, epidemiological, cohort study followed up from birth into young adulthood. Parent interviews and behavioral observations at the age of 3 months were conducted to assess child-rearing practices and mother-infant interaction in the home setting and in the laboratory. In 279 participants, anthropometric characteristics, low-density lipoprotein and high-density lipoprotein cholesterol, apolipoproteins, and triglycerides were recorded at age 19 years. In addition, structured interviews were administered to the young adults to assess indicators of current lifestyle and education. Results: Adverse early-life interaction experiences were significantly associated with lower levels of high-density lipoprotein cholesterol and apolipoprotein A1 in young adulthood. Current lifestyle variables and level of education did not account for this effect, although habitual smoking and alcohol consumption also contributed significantly to cardiometabolic outcomes. Conclusions: These findings suggest that early parental child-rearing behavior may predict health outcome in later life through its impact on metabolic parameters in adulthood. MetS = metabolic syndrome; HDL = high-density lipoprotein; LDL = low-density lipoprotein; SGA = small for gestational age; SUQ = Substance Use Questionnaire; TLFB = timeline followback; BMI = body mass index.
