Weak associations between the daily number of suicide cases and amount of daily sunlight.

Abstract: Several environmental factors with periodic changes in intensity during the calendar year have been put forward to explain the increase in suicide frequency during spring and summer. In the current study we investigated the effect of averaged daily sunshine duration of periods with different lengths and ‘lags’ (i.e. the number of days between the last day of the period for which the averaged sunshine duration was calculated and the day of suicide) on suicide risk. We obtained data on daily numbers of suicide cases and daily sunshine duration in Hungary from 1979 to 2013. In order to remove the seasonal components from the two time series (i.e. numbers of suicide and sunshine hours) we used the differencing method. Pearson correlations ( n = 22,950) were calculated to reveal associations between sunshine duration and suicide risk. The final sample consisted of 122,116 suicide cases. Regarding the entire investigated period, after differencing , sunshine duration and number of suicides on the same days showed a distinctly weak, but highly significant positive correlation in the total sample ( r = 0.067; p = 1.17*10 − 13 ). Positive significant correlations (p ˂ 0.0001) between suicide risk on the index day and averaged sunshine duration in the previous days (up to 11 days) were also found in the total sample. Our results from a large sample strongly support the hypothesis that sunshine has a prompt, but very weak increasing effect on the risk of suicide (especially violent cases among males). The main limitation is that possible confounding factors were not controlled for.

Attempts to analyse Anguillicola crassus infection and the humoral host response in eels (Anguilla anguilla) of Lake Balaton, Hungary

Abstract: Since the introduction of Anguillicola crassus into Europe, anguillicolosis has been a considerable problem in several countries. From 1991, periodical eel mortality occurred in Lake Balaton, Hungary. However, eels with a worm burden of 20 to 50 parasites did not show severe swimbladder lesions, which observation cast doubts on the primary aetiological role of the parasite in the eel kill. In order to study the pathology of the infection, from the spring of 1996 until October of the same year, 51 eels were collected from two regions of Lake Balaton and examined for swimbladder changes. To detect humoral antibodies, an enzyme-linked immunosorbent assay (ELISA) was performed, using cuticular-oesophageal worm antigen. The results of the test show the applicability of the method. However, no direct correlation was found between antibody levels or the intensity of infection and the swimbladder lesions. The low level of specific antibodies and the increasing severity of swimbladder changes in the autumn suggest that parasite-induced immunity is insufficient to prevent reinfection.

Ultrasonographic study of feline lower urinary tract diseases: 32 cases.

Abstract: The objective of the study was to describe the ultrasonographic findings of urinary bladder urolithiasis and to determine the diagnostic value of the technique in feline lower urinary tract diseases (LUTD). Physical examination of the urinary system and routine clinicopathological analysis of the blood and urine were performed on 32 cats presented with clinical symptoms of LUTD. Cystosonography was done on all of the cats, while plain radiography was performed on 8 and double contrast cystography on 2 cats. Sonography of the bladder provided the following diagnoses: urolithiasis and chronic cystitis: 24 cases, chronic cystitis without urolithiasis: 4 cases, bladder neoplasm: 1 case, negative sonographic finding: 3 cases. Bladder calculi and/or plugs were diagnosed easily, up to a size of 2 mm, according to acoustic shadowing and/or reverberation and gravitation. When the bladder was empty, it was filled up with physiologic saline solution to visualise its contents more easily. Sonography proved to be a useful technique for diagnosing urinary bladder calculi and/or plugs even when they were radiolucent and for distinguishing among the different causes of LUTD. Although ultrasonography is a valuable diagnostic tool, radiography is still necessary to explore lower urinary tract diseases, especially when cystosonography provides negative results or urethral obstruction is suspected.
