Seasonal Variations of the Incidence of Ruptured Abdominal Aortic Aneurysm at the Territory of the South Serbia Literature data on the association between the incidence of ruptured abdominal aorta ...and seasons are contradictory. The influence of climatic factors on the rupture of abdominal aorta is geographically dependent. The aim of this research was the investigation of the connection between the incidence of ruptured abdominal aorta and seasons at the territory of the southern Serbia. In this retrospective study, 59 consecutive patients, who were hospitalized in the Vascular Surgery Clinic, Clinical Center Nis, between 2008 and 2011, were involved, having the rupture of the infrarenal segment of the abdominal aorta. The incidence of the ruptured aneurysm of the abdominal aorta was analyzed with regard to calendar years, seasons and months. There was no significant connection between calendar year (χ2 test=3,836, p=0,28), seasons (χ2 test=3,4, p=0,334) and months (χ2test =11,109, p=0,434) and the incidence of the disease. According to the results of this study, it can be concluded that the incidence of ruptured abdominal aortic aneurysm in the southern Serbia is not related to seasons and months during the year.
Changes in the Incidence of Gestational Trophoblastic Disease - 2000-2010 - Our Experience Gestational trophoblastic disease (GTD) is a group of rare tumors that involve abnormal growth of cells ...inside a woman's uterus. The aim of the paper was to report the incidence of GTD in the University Hospital Center during a ten-year period. The retrospective analysis involved all medical records of women who were treated for GTD in our clinic. Histopathologic report of abortion specimen with gestational trophoblastic disease was registered and we calculated the incidence of births, abortions and total pregnancies. There were 104 patients who were treated in our clinic. The overall incidence of GTD was 1,26 per 1000 deliveries. According to our experience, a lower socio economic status may be a risk factor for GTD, apart from younger age, at least one delivery and more abortions in anamnesis.
We analyze price responses to large restaurant VAT rate reductions in two different European countries. Our results show that responses in the short and medium run were clustered around two focal ...points of zero pass-through and full pass-through. Differences between independent restaurants and chains is the key explanation for this pattern. While nearly all independent restaurants effectively ignored the tax reductions and left consumer prices unchanged, a substantial fraction of restaurants belonging to chains chose a rapid and complete pass-through. In the longer run, prices converged, but primarily through a price reversion among chain restaurants. The stark difference in price responses does not appear to arise because of different market characteristics such as location, initial price levels, meal types and restaurant segment.

Infertility is a disease characterized by the failure to establish a clinical pregnancy after 12 months of regular and unprotected sexual intercourse. It is estimated to affect between 8 and 12% of ...reproductive-aged couples worldwide. Males are found to be solely responsible for 20–30% of infertility cases but contribute to 50% of cases overall. Secondary infertility is the most common form of female infertility around the globe, often due to reproductive tract infections. The three major factors influencing the spontaneous probability of conception are the time of unwanted non-conception, the age of the female partner and the disease-related infertility. The chance of becoming spontaneously pregnant declines with the duration before conception. The fertility decline in female already starts around 25–30 years of age and the median age at last birth is 40–41 years in most studied populations experiencing natural fertility. The disease-related infertility may affect both genders or be specific to one gender. The factors affecting both genders' fertility are hypogonadotrophic hypogonadism, hyperprolactinemia, disorders of ciliary function, cystic fibrosis, infections, systemic diseases and lifestyle related factors/diseases. Premature ovarian insufficiency, polycystic ovary syndrome, endometriosis, uterine fibroids and endometrial polyps may play a role in female infertility. Male infertility may be due to testicular and post-testicular deficiencies. Semen decline that has been observed over the years, endocrine disrupting chemicals and consanguinity are other factors that may be involved.
