ABSTRACTObjectives: To investigate the relationship between different clinical findings and condyle position. Methods: Tenderness on masseter (MM), temporal (TM), lateral pyterigoid (LPM), medial pyterigoid (MPM) and posterior cervical (PSM) muscles, limitation, deviation and deflection in opening of mouth, clicking, crepitating, tenderness on lateral palpation of temporomandibular joint (TMJ) area for each side of 85 patients were evaluated. Each side of patients was categorized into the clinical findings: no sign and/or symptom of temporomandibular dysfunctions (TMDs), only extraarticular findings and only intraarticular findings, extra and intraarticular findings. Condyle positions of 170 TMJs were determined the narrowest anterior (a) and posterior interarticular distance (p) on midsagittal MRIs of condyles and expressed as p/a ratio and these ratio were transformed into logarithmic base e. Spearman’s Correlation was used to investigate the relationship between the condyle position and the clinical findings. The difference between the condyle positions of different groups was tested by T test. Reliability statistic was used to determine intra-observer concordance of two measurements of condylar position. Results: A significant relationship was found between the condyle position and tenderness of PSM. There was no significant difference between the groups in aspect of the condyle position. Occlusion and condyle position correlated with significantly. Conclusions: The inclination of the upper cervical spine and craniocervical angulations can cause the signs and symptoms of TMD and condyle position is not main cause of TMDs alone but it may be effective together with other possible etiological factors synergistically.

Background: Fever is one of the most common causes of children’s referral to the emergency department, for which in 20% of cases no clear source is found. Latent pneumonia is not easily differentiable as one of the differential diagnoses of fever of unknown origin (FUO). This study aimed to determine the relationship between FUO and latent pneumonia in feverish children referring to pediatric emergency department. Materials and Methods: The present analytical research was carried out on 220 children with FUO aged 3-36 months referred to pediatric hospital of Bandar Abbas, Iran in 2019. To find the signs and symptoms, demographic information, history, and physical examination results were recorded by a physician using a predetermined checklist. Chest x-ray and blood sample were prepared for white blood cell (WBC) count, C-reactive protein (CRP), and absolute neutrophil count (ANC). Results: The mean age of the patients was 18.38±8.6 months. There was no significant difference between the mean fever, pulse rate, respiratory rate, WBC count, erythrocyte sedimentation rate (ESR), and ANC among the three groups differentiated by their diagnosis. The mean CRP in the bacterial pneumonia group was 68.17±24.13, while it was 35.00±20.43 in the viral infection group and 35.71±26.20 in the group of other diseases; the difference was statistically significant (P=0.004). Conclusion: Although there was no significant difference between WBC, ANC, and ESR and latent pneumonia, there was a significant difference between CRP and latent pneumonia, whose value was larger in these patients.

Abstract Background Pulmonary vascular resistance (PVR) is an essential parameter assessed during cardiac catheterization. It is used to confirm pulmonary vascular disease, to assess response to targeted pulmonary hypertension (PH) therapy and to determine the possibility of surgery, such as closure of intra-cardiac shunt or transplantation. While PVR is believed to mainly reflect the properties of the pulmonary vasculature, it is also related to blood viscosity (BV). Objectives We aimed to assess the relationship between measured (mPVR) and viscosity-corrected PVR (cPVR) and its impact on clinical decision-making. Methods We assessed consecutive PH patients undergoing cardiac catheterization. BV was assessed using the Hutton method. Results We included 465 patients (56.6% female, median age 63y). The difference between mPVR and cPVR was highest in patients with abnormal Hb levels (anemic patients: 5.6 [3.4–8.0] vs 7.8Wood Units (WU) [5.1–11.9], P<0.001; patients with raised Hb: 10.8 [6.9–15.4] vs. 7.6WU [4.6–10.8], P<0.001, respectively). Overall, 33.3% patients had a clinically significant (>2.0WU) difference between mPVR and cPVR, and this was more pronounced in those with anemia (52.9%) or raised Hb (77.6%). In patients in the upper quartile for this difference, mPVR and cPVR differed by 4.0WU [3.4–5.2]. Adjustment of PVR required Conclusions We report, herewith, a clinically significant difference between mPVR and cPVR in a third of contemporary patients assessed for PH. This difference is most pronounced in patients with anemia, in whom mPVR significantly underestimates PVR, whereas in most patients with raised Hb, mPVR overestimates it. Our data suggest that routine adjustment for BV is necessary.

SUMMARY:One hundred multiple sclerosis (MS) patients were compared to healthy controls to determine the prevalence of diabetes mellitus in their families. Significantly, more MS patients than controls were diabetic or reported at least one first degree relative (parent, sibling, child) with diabetes. The relationship between MS and diabetes persisted when second degree relatives (grandparents, aunts and uncles) were taken into consideration.A greater percentage of MS patients with another MS relative were diabetic or reported a first degree relative with diabetes mellitus than MS patients without an MS relative. However the difference was not statistically significant. Nor was there a significant difference when percentages reporting either a first or a second degree relative with diabetes were compared.

Background: Several studies have demonstrated an association between obesity and migraine. It’s still unclear whether migraine is the cause or it's the result of obesity. Objective: We investigated the prevalence of migraine among obese and non-obese individuals and analyzed the relationship between migraine prevalence and obesity. Patients and Methods: This is cross-sectional observational study was carried out at the neurology outpatients’ department of the Rizgary Teaching Hospital in Erbil, Iraq, from July 1st , 2018 to September 30, 2019. We interviewed and examined 300 persons, both obese (n=154) and non-obese (n=146), and of both gender. All of them were adults (>18 years old). Each person's weight, height, body mass index (BMI), and waist circumference were measured.The diagnosis of migraine was made according to the International Headache Society’s criteria. Obesity was present if the individual’s BMI is ≥30 and/or waist-to-hip ratio is >0.9 in females and >1.0 in males. Results: Out of the 300 persons, 14 males (8.5%) got migraines while migraine was found in 37 females (27.4%), irrespective of their weight. Out of the 300 persons, the prevalence of migraine among obese individuals was 21.4% (n=33) and while in non-obese individuals was 12.3% (n=18). There was a statistically significant difference between the groups (p-value=0.045). The overall prevalence of migraine was 16.9% of the persons interviewed. Conclusion: The results showed that migraine is more prevalent among obese persons than non-obese persons and the difference was statistically significant. Keywords: Migraine, obesity, BMI, headache

Purpose This study aims to apply signaling theory to examine whether corporate social responsibility (CSR) disclosure can deliver effective signals to stakeholders to increase a firm’s competitive advantage in China. Whether ownership patterns or environmental sensitivity causes a significant difference in the relationship between a firm’s CSR disclosure and competitive advantage is also examined. Design/methodology/approach Data analysis is based on a regression model. Content analysis is performed to convert qualitative CSR information of Chinese firms into quantitative data, while intellectual capital (IC) is used as a proxy variable for competitive advantage. Findings The difference in competitive advantage impairment between environmentally sensitive industries (ESIs) and non-environmentally sensitive industries (NESIs) is significant. Further comparisons on the relationship between overall CSR disclosure and competitive advantage among state-owned enterprises, privately owned enterprises, ESIs and NESIs suggest that the relationship is negative. Research limitations/implications The study extends research of strategic CSR to signaling theory and competitive advantage. In particular, a research using IC as a proxy for competitive advantage is rare. It also contributes to the literature on competitive advantage and strategic CSR by examining the effects of both CSR disclosure and IC. Originality/value This paper provides evidence related to stakeholders’ reaction to managers’ various CSR strategies in China. The contribution of this study is that it confirms that different CSR initiatives have different effects on the competitiveness of enterprises in China.

Critical bandwidth measurements and sensitivity prediction from the acoustic reflex (SPAR) test results were obtained on 20 normal-hearing and two groups of 10 hearing-impaired subjects each representing mild-to-moderate and severe hearing loss. Results of critical bandwidth measurements indicated that for center frequencies of 1000 and 2000 Hz the critical bandwidth was significantly greater for the hearing-impaired subjects. A statistical analysis of the difference in critical bandwidth between those predicted by the SPAR test to have a mild-to-moderate hearing loss and those subjects for whom the test predicted severe hearing loss indicated no differences in critical bandwidth at 2000 Hz. A significant difference was found at 1000 Hz but in the wrong direction. Analysis of the relationship between predicted slope of hearing loss and critical bandwidth also failed to show significance. Although the data for hearing-impaired subjects fail to support the rationale for the SPAR test, the results for the entire research sample offer substantial support. Further, the ability of the test to predict categorically degree of hearing loss was also strongly supported.

This study aims to analyze the relationship between the level of knowledge and behavior of the Sundanese Muslim community in Bandung about halal food and beverage products. The method used in this research is descriptive and verifikatif. The data were collected using questionnaires, completed with observation. Data analysis using validity test, reliability test, linear regression, correlation, hypothesis test, and coefficient of determination. The correlation test result is 0.376, which shows that it is in the interval 0.20 - 0.399, and the coefficient of determination test shows the influence of 0.142. This means that the influence of knowledge level on the behavior of Muslim sunda society is 14.2%. The difference of 85.8% is the influence of other factors not examined. This figure indicates that the increased knowledge of respondents on halal products will increase the behavior in consuming halal products.

Since the beginning of the private equity industry in the 1980s, it has evolved and adopted new strategies and methods for generating returns to investors. As the industry grew, deals became harder to find as the buyer market grew immensely and what deals remained appeared picked over. Enter the secondary buyout (SBO). This strategy involves one financial sponsor buying a portfolio company from another financial sponsor. This thesis attempts to fill a gap in the field of research in two ways. First, this thesis analyzes the difference in value creation using a longitudinal and matched-sample approach. This approach is unique in that I will only analyze data for which information on the SBO, the preceding LBO, and the following exit are all available. Second, this thesis looks specifically at the relationship between LBOs and SBOs in an attempt to provide a practical application of the analysis. Additionally, most studies stray away from performing analysis on the U.S. market due to the limited data availability, but this approach ignores one of the largest private equity markets in existence. This thesis will look solely at U.S. buyouts. I find no significant difference in the relative change in enterprise value from acquisition to exit for LBOs or SBOs. Further, there is a statistically significant negative relationship between the holding period and annualized change in EV for both LBOs and SBOs. Finally, while the results were not significant, there is a slight negative relationship between the EV change of LBOs to the EV change of SBOs.

Abstract Background Migraine is a common clinical primary headache with unclear aetiology. In recent years, studies have shown that migraine is related to patent foramen ovale, and some patients with migraine have white matter lesions. However, the relationship among the three is unclear.Objective To explore the characteristics of white matter lesions (WMLs) in migraine patients with patent foramen ovale and to predict the occurrence of patent foramen ovale through magnetic resonance imaging (MRI) characteristics in patients with migraine.Methods Seventy-seven patients clinically diagnosed with migraine were examined by transcranial Doppler ultrasound (cTCD) and MRI. The patients were grouped according to the presence of WMLs, with matching by age, sex, hypertension, diabetes, PFO and other characteristic data. We observed the MRI fluid attenuation inversion recovery sequence (FLAIR) image and compared and analysed the difference in WMLs between the PFO-positive group and the PFO-negative group.Results There were 42 cases and 35 cases of migraine with and without WMLs, respectively. A statistically significant difference in near-cortical WMLs with PFO in migraine patients was observed (P=0.001). Logistic regression analysis adjusted by age, sex, hypertension and diabetes identified PFO status as the sole determinant for the presence of near-cortical WMLs (OR = 0.14; 95%CI 0.045–0.421; p < 0.001)Conclusion Near-cortical white matter lesions in migraine patients are related to PFO. Transcranial Doppler ultrasonography may reveal more PFO in patients with migraine and near-cortical WMLs.

Background and Purpose:Cryptococcalmeningitis (CM) is a serious fungal infection that especially affectspatients with human immunodeficiency virus (HIV). In this regard,the present retrospective study aimed to analyze the clinical and laboratory features and therapeutic outcomes of patients with CM admitted to two teaching referral centersin the north of Iran during 2011-19. Materials and Methods:This study was performed onall the hospitalized patients diagnosed with CM in two therapeutic centers of infectious diseases in the north of Iran. The required data,such as demographic characteristics and clinical and paraclinical features of patients, were extracted and entered in the information forms. Finally, the collected data were analyzed inSPSSsoftware(version16). Results:For the purpose of the study, records of 12confirmed CM patients were evaluatedin this research. Based on the results,75% of the patients were male. Moreover,the average age of the subjects was 40.33± 8.93 years old and 66.6%ofthem(n=8) were HIV-positive. Other underlying diseases among HIV-positive patients included infection with hepatitis C virus (25%) and a history of tuberculosis (25%). In total, threeHIV-negative patients suffered from Hodgkin lymphoma (25%), sarcoidosis (25%),and asthma (25%) and one patient (25%) had no underlying disease. Headache (75%), weakness,and fatigue (75%) were the most common symptoms among the participants. The cluster of differentiation 4count in all HIV-positive patients was less than 100 cells/μl. There was no significant difference between symptoms in HIV-positive and HIV-negative patients. Besides, no significant difference was observed between the groups of HIV-positive and HIV-negative patients regarding the period between the onset of symptoms and diagnosis of CM,the length of hospital stay,and the duration of antifungal medication consumption. In total,three patients (25%) expired,and six patients recovered. The CM recurred in two HIV-negative and oneHIV-positive subjects;the two HIV-negative patients were treated,whilethe HIV-positive patient expired due to this recurrence. Conclusion:Clinical features and cerebrospinal fluid parameters were not different in HIV-positive and HIV-negative participants. Despite the fact thatCM is not common in Iran, due to the increasing number of immunosuppressive patients, the differential diagnosis of CM should be considered for patients with signs and symptoms of infection in the central nervous system.
