The safety of the reproductive organs has a great positive impact on the human psyche, so early and accurate diagnosis of scrotal disorders by ultrasound was one of the necessities that puts the individual in the correct path of treatment. This study was conducted to evaluate the significance of ultrasound imaging technology in the diagnosis of varicocele and its relationship with sperm characteristics through semen analysis. We retrospectively reviewed a total of 281 male patients who underwent scrotum ultrasound at King Abdul-Aziz University Hospital-Radiology Department between 2017 and 2019 with age range of (11-76) years. Ultrasound result showed 119 (42.3%) had varicocele. Semen analysis was performed for 143 patients and the results showed a significant correlation between sperm characteristics and varicocele disorder (p < 0.001). Imaging of the scrotum by ultrasound is of great importance in diagnosing various andrology diseases, including varicocele, which have clear effects on sperm count and motility.

Summary Objective: The aim of this study is to gain insight into the individual user acceptance of PACS by the radiology department staff of the Ghent University Hospital. Hereto a basic – direct effects only – form of UTAUT was assessed. Methods: Ninety-four questionnaires were distributed and 56 usable questionnaires were returned (19 radiologists – 37 technologists). The questionnaire consisted of scales of Venkatesh et al. [13] for performance expectancy (PE), effort expectancy (EE), facilitating conditions (FC), social influence (SI), self-efficacy (SE), attitude (ATT), anxiety (ANX) and behavioral intention (BI), and a scale of Moore et al. [22] to assess the perceived voluntariness of PACS-use. Results: The reliability of all scales, except FC and voluntariness, was acceptable to good. The voluntariness scale was divided into a mandatoriness (MAN) and a voluntariness (VOL) measure. Both radiologists and technologists seem to welcome PACS, with radiologists having higher ratings on PE, EE, ATT, VOL and BI. Only PE and FC were salient for predicting BI, while EE and SI were not salient. Variance explained in behavioral intention to use PACS was 48%. Conclusion: Both radiologists and technologists were positive towards PACS and had strong intentions to use PACS. As other healthcare professionals, they appear to make their technology acceptance decision independent from their superiors, hereby focusing on usefulness rather than on ease of use. It is also important that support is supplied. Basic UTAUT is an adequate model to assess technology acceptance in a radiological setting.

This research aims at measuring the service quality in public and private banking sector and identifying its relationship to customer satisfaction and behavioral intention. The study was conducted among 500 bank customers by using revised SERVQUAL instrument with 26 items. Behavioral intention of the customers was measured by using the behavioral intention battery. The researcher has used a seven point likert scaling to measure the expected and perceived service quality (performance) and the behavioral intention of the customer. The instrument was selected as the most reliable device to measure the difference-score conceptualization. It is used to evaluate service gap between expectation and perception of service quality. Modifications are made on the SERVQUAL instrument to make it specific to the Banking sector. Questions were added to the instrument like Seating space for waiting (Tangibility), Parking space in the Bank (Tangibility), Variety of products / schemes available (Tangibility), Banks sincere steps to handling Grievances of the customers (Responsiveness). The findings of the study revealed that the customer’s perception (performance) is lower than expectation of the service quality rendered by banks. Responsiveness and Assurance SQ dimensions were the most important dimensions in service quality scored less SQ gap. The study concluded that the individual service quality dimensions have a positive impact on Overall Satisfaction.

Objectives: 1. Estimating the ratios of clinical and paraclinical signs of post-term newborns hospitalized at Pediatric Department of Hue University Hospital. 2. Identifying the relation between clinical signs and paraclinical signs. Materials and Method: 72 post- term babies < 7 days of life hospitalized at NICU from 2010/5 to 2011/4. Classification of post - term newborn was based on WHO 2003: gestational age ≥ 42 weeks with clinical manifestations: desquamation on press with fingers or natural desquamation, withered or meconial umbilicus, meconial long finger nails (*) or geatational age still < 42 weeks with theses clinical manifestations (*). Data were recorded on a clinical record form. Per-protocol analysis of clinical outcomes was performed by using Medcalc 11.5 and Excell 2007. Analyses used the χ2 test or Fisher's exact test for categorical data; Student's t test was used for continuous data and the Mann-Whitney U test for nonparametric data. Data were presented as means or proportions with 95% CIs. Results: Clinical characteristics: Tachypnea and grasp were main reasons of hospitalisation (48.61%). Poor feeding, vomitting (16.67%). Asphyxia (8.34%). Jawndice (6.94%). Hypothermia < 36.50C (13.89%), fever (13.89%). Tachypnea (59.72%). Bradycardia (1.39%). Poor feeding (11.11%). Hypertonia (9.72%). Paraclinical characteristics: Erythrocytes < 4.5.1012/l (51.39%), Leucocytes 5 – 25.103/mm3 (81.94%), Thrombocytes 100- 400.103/mm3 (94.44%). Hemoglobinemia < 10mg/l (67.61%). Maternal characteristics: Menstrual cycles regular (75%). Primiparity (75%). Amniotic volume average (70.42%), little (29.58%). Aminiotic liquid clair (62.5%), aminiotic liquid yellow (4.17%), aminiotic meconial liquid (33.33%). Maternal manifestation of one of many risk factors consist of genital infection; urinary infection; fever before, during, after 3 days of birth; prolonged delivery; medical diseases influence the foetus (75%). The relation between clinical signs and paraclinical signs: There was significantly statistical difference: between gestationnal age based on obstetrical criteria and amniotic volume on ultrasound (p < 0.05); between birth weight and glucosemia p < 0.02). There was conversional correlation of average level between erythroctes number and respiratory rate (r = - 0.5158; p < 0,0001), concordance correlation of weak level betwwen leucocytes number and respiratory rate r = 0.3045; p = 0.0093). Conclusion: It should made diagnosis of postterm baby based on degree of desquamation. The mother who has menstrual cycles regular is still delivered of a postterm baby. A postterm baby has the individual clinical and paraclinical signs.

Objectives: Artificial insemination with sperm preparation and inseminate to the uterus is a common method of infertility treatment. Currently two methods used for sperm washing is “swim-up” and “gradient”. Materials and methods:cross-sectional description in 166 cycles of artificial insemination in Hue University Hospital from April, 2012 to March, 2013 in order to compare effectiveness between “swim-up” and “gradient” methods. Samples were collected randomly into two methods. Results:Results of sperm preparation in both methods are equivalent in terms of the following parameters total sperm count, total number of progressive sperm, total good morphology sperm. However, “gradient” method results in higher number of progressive sperm in case with slow motility (38.3% vs. 26.1%) or abnormal morphology (34.9% vs. 19.7 %) compared with “swim-up” method. Pregnancy rates after artificial insemination were similar between two preparation methods. Conclusion:In case of slow motility sperm and abnormal morphology, “gradient” method should be used to increase the number of progressive sperms. Pregnancy outcome depends on many factors other than preparation methods. Key words: Artificial insemination, sperm preparation, infertility treatment

Background: The aim of this study was to compare consequences in single and triple testicular biopsy by biopty gun in pubertal rats using histological and immunohistochemical analysis. Methods: Thirty-two Sprague-Dawley male rats were used as the experimental model. The rats were randomly divided into three study groups. The rats from the first group (n = 12) received a single-biopsy of upper pole of the left testis, while the rats from the second group (n = 10) received triple-biopsy of upper and lower poles and lateral surface of left testis. The third group (n = 10) was a control group. On the eightieth day after the biopsy in all rats bilateral orchiectomy and funiculectomy were performed to obtain testicular tissue and sperm for analysis. The consequences of the puncture were observed by pathohistology, immunohistochemistry and semen analysis. Results: The results of the study showed lower percentage of sperm count (14.5 mill/mL vs. 16 mill/mL, p = 0.130), sperm motility (24.6% vs. 32.7%, p > 0.05), abnormal sperm (30% vs. 27%, p > 0.05), atrophic tubules (21% vs. 6%, p < 0.001), volume (1.7 mL vs. 2.28 mL, p < 0.01) and apoptotic index (1.56 vs. 1.19, p = 0.650) in the testes with a triple-biopsy compared to the testes with a single-biopsy. Semen analysis showed a borderline significant difference between the group with triple-biopsy where sperm count was lower than it in the control group (14.5 mill/mL vs. 17.5 mill/mL, p = 0.05). A single-biopsy has little effect on the testis, especially on overall fertility. A triple-biopsy showed higher degree of the testicular damage but without a significant impact on overall fertility. Semen analysis showed that single- and triple-biopsies did not have a significant effect on sperm count, motility and morphology. Conclusion: Biopty gun procedure is a cheap, simple and reliable method for testicular biopsy in rats without a significant effect on sperm count, motility and morphology.

The Impact

The aim was to examine the impact on interpreters’ health knowledge, attitudes and self-evaluated skills after they participated in a pilot health introduction course at a university hospital in Denmark. The study was conducted as an intervention study using a questionnaire with both closed and open-ended questions. The questionnaire was distributed to interpreters one week before the six-week course started, and again at one week and at three months after course completion. Level of knowledge was calculated based on the number of answers to 18 multiple-choice questions on common health issues, diagnoses and treatments. Of the 100 interpreters who registered for the course, 86 completed the course, and 61 of these participants (70%) completed both the baseline and the one-week questionnaire. The mean knowledge score increased from 48 ( SD 6.9) at baseline to 52 ( SD 3.4; p < 0.001) one week after the course and was 51 ( SD 7.3; p < 0.001) three months after the course ( n = 55). Participants who increased their knowledge score the most were those with the least interpreter experience ( p = 0.001). One week after the course, most participants (83–95%) agreed that the individual lessons had been useful in their subsequent interpreting activities and that they had gained useful information. The health introduction course appeared to be beneficial for interpreters. This study highlights the need for greater focus on education for interpreters working in the healthcare sector.

The risk prediction of future cardiovascular events is mainly based on conventional risk factor assessment by validated algorithms, such as the Framingham Risk Score, the Pooled Cohort Equations and the European SCORE Risk Charts. The identification of subclinical atherosclerosis has emerged as a promising tool to refine the individual cardiovascular risk identified by these models, to prognostic stratify asymptomatic individuals and to implement preventive strategies. Several imaging modalities have been proposed for the identification of subclinical organ damage, the main ones being coronary artery calcification scanning by cardiac computed tomography and the two-dimensional ultrasound evaluation of carotid arteries. In this context, echocardiography offers an assessment of cardiac calcifications at different sites, such as the mitral apparatus (including annulus, leaflets and papillary muscles), aortic valve and ascending aorta, findings that are associated with the clinical manifestation of atherosclerotic disease and are predictive of future cardiovascular events. The aim of this paper is to summarize the available evidence on clinical implications of cardiac calcification, review studies that propose semiquantitative ultrasound assessments of cardiac calcifications and evaluate the potential of ultrasound calcium scores for risk stratification and prevention of clinical events.

Abstract Background Varicocele is an abnormally dilated pampiniform plexus of the veins within the spermatic cord and is considered the most common correctable cause of male factor infertility. Many approaches are described for treatment either surgical (tradition inguinal, subinguinal, and laparoscopic) or non-surgical percutaneous embolization. During the period from August 2017 to December 2018, we prospectively analyzed the preoperative and post-operative alteration of semen parameters (at 3 and 9 months) of the data collected from 63 patients with clinically evident varicocele referred to our tertiary hospital. Patients were divided into two groups: group 1, thirty-three patients who underwent subinguinal microsurgical ligation, and group 2, thirty patients who underwent percutaneous embolization. Results Sixty-three patients enrolled in this study were divided in two groups: group 1, patients who underwent surgery, and group 2, patients who underwent embolization; the mean age is 24.6 ± 1.27 years in group 1 and 23.7 ± 2 years in group 2; there was no statistically significant difference between the two groups as regards BMI, diabetes, hypertension, and smoking. Bilaterality was present in 15.2% of group 1 patients and 10% in group 2 patients (P value 0.06). Most of the patients were classified as grades 2 and 3 with no statistical significance regarding severity of the disease. Preoperative semen parameters for patients including sperm count, motility, and abnormal forms showed no statistically significant difference between the two groups. Post-intervention semen analysis was done twice during follow-up after 3 months and 9 months from the date of intervention. After 3 months, the semen parameters were improved in both groups in spite of the higher sperm count in group 2 but with no statistical significance. After 9 months follow-up, semen analysis showed persistent increase in sperm mobility in group 1 patients in comparison to group 2 patients. Both groups had better improvement in count of normal form with no statistical significant change. Conclusion Improvement of semen parameters while treating primary varicocele by either subinguinal microsurgery approach or percutaneous embolization shows equivalent outcomes.

The effect of chronic oral exposure to arsenic on male mouse testicular and accessory sex organ weights, sperm parameters and testicular marker enzymes was studied. In addition, the distribution of arsenic in reproductive organs was measured using atomic absorption spectrophotometry. Sodium arsenite administered to mice (Mus musculus) via drinking water at a dose of 53.39 βmol/L (4 ppm As) for 365 days caused a decrease in the absolute and relative testicular weight. However, epididymal and accessory sex organ weight was similar to control. The activities of marker testicular enzymes such as sorbitol dehydrogenase, acid phosphatase and 17β-hydroxysteroid dehydrogenase (17β-HSD) were significantly decreased, but those of lactate dehydrogenase and γ-glutamyl transpeptidase (γ-GT) were significantly increased. A decrease in sperm count and sperm motility, along with an increase in abnormal sperm, was observed in arsenite-exposed mice. A significant accumulation of arsenic in testes, epididymis, seminal vesicle and prostate gland was observed in treated animals. Thus long term exposure (365 days) at the dose level of 53.39 μmol/L sodium arsenite (4 ppm As), to which human beings are likely to be exposed via drinking water, may cause testicular and spermatotoxic effect.

Purpose The purpose of this paper is to study the differentiated impact of factors that influence the propensity to entrepreneur in a sample of people in Chile. A distinction is made between individuals that live in primary cities and secondary cities. The differentiating factors are socio‐cultural aspects (reference models – positive examples of entrepreneurs – and perception of social fear of failure) and the gender of the individual. Design/methodology/approach For the research data from the survey used in Chile by the Global Entrepreneurship Monitor for the years 2010 and 2011 were used. A logit model was used to determine the differentiated impact of the analysed factors and interactions were done using the method proposed by Corneliâen and Sonderhof (2009). Findings These showed that the fact that an individual lives in a secondary city decreases his entrepreneurship probability. The positive impact that the reference models have is weaker in women. Contrary to what was expected, the negative impact of the fear of failure perception is weaker in women. Practical implications These results have the implications to suggest focused public policies and differentiations that consider the socio‐cultural, territorial (focused in cities) and gender aspects. Originality/value The research contributes by giving empirical evidence of the existence of the negative impact of living in a secondary city and of differentiated effects of socio‐cultural factors from the gender perspective.
