ABSTRACT
Leptospirosis is one of the most common zoonotic infections and a major problem in terms of both veterinary medicine and public health. However, the disease is under-recognised and under-diagnosed worldwide, particularly in horses. Clinical leptospirosis in horses is mainly associated with recurrent uveitis (ERU), which has recently been studied more intensively, and reproductive disorders, the epidemiology of which is still relatively poorly understood. To enhance our comprehension of abortions caused by leptospirosis in horses and to identify the causative strains, a serological study was carried out with subsequent molecular characterisation of the isolate obtained. Using the microscopic agglutination test (MAT), serum samples from mares that aborted and foetal fluids (when available) were tested for antibodies against Leptospira spp. Furthermore, bacteria isolation from kidney cultures was conducted. Of 97 mare serum samples, 21 (21.64%) tested positive, with Grippotyphosa and Pomona being the most frequently detected serogroups. A significantly higher seroprevalence was found in aborting mares compared to the healthy horse population from the same geographical area, as well as a pronounced seasonal variation. Leptospiral antibodies were not detected in any of the foetal fluids, but isolation was successful in 1 case out of 39 (2.56%). Genotyping by multilocus sequence typing (MLST) and core genome multilocus sequence typing (cgMLST) identified the obtained isolate as Leptospira kirschneri, serogroup Pomona, serovar Mozdok. Further surveillance and molecular typing of Leptospira strains causing abortion in horses would be invaluable in understanding the prevalence and impact of leptospirosis on equine reproductive health in Europe.
ABSTRACT
Leptospirosis is re-emerging zoonotic bacterial disease of global importance that affects domestic and wild animals and humans. Due to the public health importance, control of disease in Croatia is being implemented by monitoring the seroprevalence of equine leptospirosis and it is regulated by the law. In the period from 2012 to 2022, a total of 61,724 serum samples from apparently healthy horses were admitted to the Laboratory for leptospires, Faculty of Veterinary Medicine University of Zagreb. Serum samples were tested for Leptospira spp. antibodies using the microscopic agglutination test (MAT). Samples were considered seropositive with a cut-off titre 1:200 for Bratislava and 1:400 for other Leptospira spp. serovars. Out of 61,724 serum samples tested, 6,665 (10.80%) were found seropositive for at least one Leptospira serovar. In the studied period, seroprevalence varied between 5.00% and 15.94%. The highest seroprevalence was found for serovar Pomona (41.98%) and serovar Grippotyphosa (31.34%), followed by Sejroe (8.03%), Icterohaemorrhagiae (7.05%) and Bratislava (6.47%). Results indicated that horses in Croatia are particularly exposed to Leptospira spp. infections. The most prevalent presumed infective serovar was Pomona increasing each year. Investigated horses were randomly selected and healthy and most seropositive horses have anamnestic titre due to previous infection. This is the first study in Europe reporting such high seropositivity for the serovar Pomona in apparently healthy horses. According to the results of the present study, the question arises of the possible evolutionary adaptation of the pathogenic serovar Pomona as dominant for horses.

Over a year into the COVID-19 pandemic, there is growing evidence that SARS-CoV-2 infections among dogs are more common than previously thought. In this study, the prevalence of SARS-CoV-2 antibodies was investigated in two dog populations. The first group was comprised of 1069 dogs admitted to the Veterinary Teaching Hospital for any given reason. The second group included dogs that shared households with confirmed COVID-19 cases in humans. This study group numbered 78 dogs. In COVID-19 infected households, 43.9% tested ELISA positive, and neutralising antibodies were detected in 25.64% of dogs. Those data are comparable with the secondary attack rate in the human population. With 14.69% of dogs in the general population testing ELISA positive, there was a surge of SARS-CoV-2 infections within the dog population amid the second wave of the pandemic. Noticeably seroprevalence of SARS-CoV-2 in the dog and the human population did not differ at the end of the study period. Male sex, breed and age were identified as significant risk factors. This study gives strong evidence that while acute dog infections are mostly asymptomatic, they can pose a significant risk to dog health. Due to the retrospective nature of this study, samples for viral isolation and PCR were unavailable. Still, seropositive dogs had a 1.97 times greater risk for developing central nervous symptoms.

The aim of this study was to determine the level of self-harm behaviors among adolescents in the general population (students of secondary schools in Zagreb, Croatia), as well as to determine if the level of self-harm behaviors differed according to financial circumstances of the family and marital status of the parents. The study was conducted in 701 adolescents (male and female, age range 14 to 19 years). A specially designed questionnaire that included family and demographic data was used to determine the family financial circumstances. The Scale of Auto-Destructiveness measuring instrument was used to assess the level self-harm. Study results revealed that 87.3% of adolescents indicated average levels of self-harm, whereas above-average and high above-average self-harm was indicated in 12.7% of the adolescents. Results also showed that single-parent families significantly differentiated the level of self-harm among adolescents of both genders, whereas financial deprivation (perception of financial stress) partially differentiated these levels. Practical implications of this study emphasize the importance of social support to parents of adolescents grown up in single-parent and/or financially challenged families.

Despite evidence that children of male war veterans with combat-related posttraumatic stress disorder (PTSD) are at particularly high risk for behavior problems, very little is currently known about suicidal behaviors in this population of youth. This study aimed to examine the prevalence and psychosocial correlates of suicide attempts among psychiatrically hospitalized adolescent offspring of Croatian male PTSD veterans. Participants were psychiatric inpatients, ages 12-18 years. Self-report questionnaires assessed demographics, suicide attempts, psychopathology, parenting style, and family functioning. The prevalence of suicide attempts was 61.5% (65.2% for girls and 58.0% for boys). Internalizing symptoms, family dysfunction, lower levels of maternal and paternal care, and paternal overcontrol were significantly associated with suicide attempts. Our findings suggest that suicide attempts are common among inpatient adolescent offspring of male PTSD veterans and that interventions targeting both adolescent psychopathology and family relationships are needed for adolescents who have attempted suicide.

Use of animals for therapeutic purposes, animal assisted therapy or AAT is a method for improving quality of life for long-term inpatients. The object of this paper was to evaluate dog companionship as a form of AAT and its effects on perception of loneliness in geriatric nursing home residents. The participants were involved in a six-month program of dog companionship three times weekly for 90 minutes. There were 21 residents included in the program, with a mean age of 80 years. Loneliness was measured by the short version of the UCLA Scale of loneliness. Comparison of test results before and after participation in the program showed that dog companionship reduces the perception of loneliness.

The aim of this research is to look into the roles of families' social situation and cohesion in adolescent auto-aggressiveness in Croatia. The research was conducted on a sample of Zagreb high school students which encompassed 701 pupils of both genders aged 14-19. The basic demographic data were obtained using the Structured Demographic and Family Data Questionnaire. Auto-aggressiveness was tested using a section of the Report on Youth Aged 11-18 and the Scale of Auto-destructiveness--SAD, whereas the family cohesion was tested with the Family Adaptability and Cohesion Evaluation Scales FACES III. The obtained results show differences according to the gender: girls are more prone to auto-aggressiveness than boys (t = -3.385, df = 565, p = 0.001) and girls more often show symptoms of destructiveness (t = -3.809, df = 637, p < 0.001) and anxiety (t = -6.562, df = 640, p < 0.001), while boys show pronounced aggressiveness (t = 2.655, df = 653, p = 0.008). Significant family factors associated with auto-aggressiveness are parents' marital status (chi2 = 18.039, df = 4, p = 0.001), their financial situation (F(2.548) = 4.604, p = 0.010), alcoholic father (chi2 = 9.270, df = 2, p = 0.010), mentally ill mother (t = 5.264, df = 541, p < 0.001), as well as mentally ill father (t = 4.744, df = 529, p < 0.001), and corporal punishment by mother (F(2.542) = 8.132, p < 0.001) or father (F(2.530) = 5.341, p = 0.005). Adolescents from split families show more auto-aggressiveness. Family cohesion appears to be considerably associated with auto-aggressiveness and the adolescents that see their families as less cohesive have more mental problems (chi2 = 29.98, df = 2, p < 0.001). There is a connection between auto-destructive behavior in adolescents and family factors. Knowledge of family's social situation and cohesion may help understand, prevent and treat auto-aggressiveness in adolescents.

AIM: To determine the presence of disorder of extreme stress not otherwise specified (DESNOS) in Croatian war veterans who suffer from combat-related posttraumatic stress disorder (PTSD). METHODS: The research included 247 veterans of the 1991-1995 war in Croatia who suffered from PTSD and were psychiatrically examined at four clinical centers in Croatia during a month in 2008. It was based on the following self-assessment instruments: The Harvard Trauma Questionnaire (HTQ): Croatian Version, the Structured Interview for Disorder of Extreme Stress (SIDES-SR), and the Mini International Neuropsychiatric Interview (MINI). RESULTS: Based on the SIDES-SR results, we formed two groups of participants: the group with PTSD (N=140) and the group with both PTSD and DESNOS (N=107). Forty three percent of participants met the criteria for DESNOS. There was a significant difference in the intensity of posttraumatic symptoms between the group with both PTSD and DESNOS and the group with PTSD only (U=3733.5, P=0.001). Respondents who suffered from both PTSD and DESNOS also reported a significantly larger number of comorbid mental disorders (U=1123.5, P=0.049) and twice more frequently reported comorbid depression with melancholic features (OR=2.109, P=0.043), social phobia (OR=2.137, P=0.036), or panic disorder (OR=2.208, P=0.015). CONCLUSION: Our results demonstrate that PTSD and DESNOS can occur in comorbidity, which is in contrast with the ICD-10 criteria. A greater intensity of symptoms and a more frequent comorbidity with other psychiatric disorders, especially depression, panic disorder, and social phobia require additional therapy interventions in the treatment processes.
