Prompt and adequate treatment of human brucellosis continues to be the most important strategy in its management, as eradication of animal brucellosis is not possible so far, and there is no adequate ...vaccine for humans. The goal of antibrucellar treatment is to alleviate and shorten the symptomatic period and reduce complications, relapses, and chronicity. Contemporary trends in the treatment of human brucellosis are postulated on the ability of
Brucellae
to persist in host macrophages through the inhibition of phagolysosome fusion and to survive for prolonged periods intracellularly without restricting basic cellular functions. As a result of this and despite satisfactory antibiotic treatment, relapses and therapeutical failures are inevitable to a certain degree. The current principles for the treatment of brucellosis advocate for a long enough treatment duration combined with antimicrobial regimens that possess activity in the intracellular acidic environment. In the future, other antimicrobial agents, immunomodulation, decrease in the intracellular acidic environment, or development of agents that would act on well-defined molecular bacterial targets, might be incorporated to improve the therapeutical effects.
In veterinary medicine, the relationship between empathy and mental health presents a complex and important aspect of professional well-being. Veterinarians are frequently exposed to numerous ...work-related stressors and are therefore more likely to experience mental health disorders and commit suicide. Due to the specific nature of the profession, veterinarians deal with negative patient outcomes, inform owners of unfavourable news, handle heavy workloads, and professional isolation. Psychological stress is a result of all these factors coming together, and it can lead to anxiety, depression, burnout, and even frequently reported suicide. Animal euthanasia has been recognised as a unique professional risk factor that can have harmful psychological effects on veterinary professionals.This paper explores the role of empathy in the mental health of veterinarians and other veterinary staff, and how this might contribute to their vulnerability to psychological stress and suicidal ideation. Empathy plays an important role in interpersonal interactions, while also influencing human-animal relationships, which adds a whole new level of complexity to the doctor-patient dynamic in this field. Veterinarians are responsible for providing compassionate care for both the animals they treat and their owners. They must manage the emotionally demanding work while preserving their mental health by balancing between providing empathetic care and sustaining their own emotional boundaries. To alleviate the negative effects of psychological stress, veterinary professionals require interventions such as peer support groups, stress management training, and mental health support programmes.
Evaluating trends in antibiotic resistance is a requisite. The study aimed to analyze the profile of multidrug-resistant organisms (MDROs) among hospitalized patients with bacteremia in intensive ...care units (ICUs) in a large geographical area. This is a 1-month cross-sectional survey for blood-borne pathogens in 57 ICUs from 24 countries with different income levels: lower-middle-income (LMI), upper-middle-income (UMI), and high-income (HI) countries. Multidrug-resistant (MDR), extensively drug-resistant (XDR), or pan-drug-resistant isolates were searched. Logistic regression analysis determined resistance predictors among MDROs. Community-acquired infections were comparable to hospital-acquired infections particularly in LMI (94/202; 46.5% vs 108/202; 53.5%). Although MDR (65.1%; 502/771) and XDR (4.9%; 38/771) were common, no pan-drug-resistant isolate was recovered. In total, 32.1% of MDR were
Klebsiella pneumoniae
, and 55.3% of XDR were
Acinetobacter baumannii.
The highest MDR and XDR rates were in UMI and LMI, respectively, with no XDR revealed from HI. Predictors of MDR acquisition were male gender (OR, 12.11; 95% CI, 3.025–15.585) and the hospital-acquired origin of bacteremia (OR, 2.643; 95%CI, 1.462–3.894), and XDR acquisition was due to bacteremia in UMI (OR, 3.344; 95%CI, 1.189–5.626) and admission to medical-surgical ICUs (OR, 1.481; 95% CI, 1.076–2.037). We confirm the urgent need to expand stewardship activities to community settings especially in LMI, with more paid attention to the drugs with a higher potential for resistance. Empowering microbiology laboratories and reports to direct prescribing decisions should be prioritized. Supporting stewardship in ICUs, the mixed medical-surgical ones in particular, is warranted.
Objectives
To assess the severity of symptoms, duration of infection and viral loads of health-care workers (HCWs) who tested positive for Coronavirus disease 2019 (COVID-19) during Omicron’s ...prevalence, in regard to vaccination and previous infection.
Methods
During 2 weeks of highest rate of COVID-19 cases in Bosnia and Herzegovina, the positive nasopharyngeal swabs were analysed in 141 HCWs by reverse transcription quantitative PCR, targeting four different genes: RdRp, E, N and nsp14. Uniformed questionnaire was used to collect relevant sociodemographic and epidemiological data from HCWs divided into four groups: unvaccinated/not previously infected (group 1); unvaccinated/previously infected (group 2); vaccinated/not previously infected (group 3); and vaccinated/previously infected (group 4).
Results
We observed that occurrence of fever and smell or taste loss were more frequent in group 1 (86.4% and 25%) and group 3 (76.9% and 19.2%), in comparison to group 2 (64.4% and 6.7%) and group 4 (69.2% and 3.8%), (
p
= 0.023 and
p
= 0.003). Although statistically not significant, group 2 (61.9%), group 3 (65.4%), and group 4 (70.8%) experienced negativization within 7 days of positive RT-qPCR test, whereas 51.2% of HCWs from group 1 tested negative later on. There is no significant difference between all four groups regarding
Ct
values of analysed genes.
Conclusion
During Omicron’s prevalence, the vaccination had less substantial effect on symptomatic disease among HCWs, while fever and loss of smell or taste were considerably less likely to occur upon reinfection. Since viral loads and negativization periods do not seem to significantly vary, irrespective of pre-existing immunity, systemic vaccination and mask-wearing should still be considered among HCWs.
We are living in times where a viral disease has brought normal life in much of the world to a halt. The novel coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ...causing coronavirus disease 2019 (COVID-19) started in December 2019 in Wuhan, China initially and in a short time crossed the European borders. After mitigating the epidemic in China, Italy became one of the most COVID-19 affected countries worldwide. International travelers are important sources of infectious diseases and a possible source of epidemic. Due to its political, geographic, and cultural similarities, Italy is one of the main economic partners of Southeast European (SEE) countries. Our data show that infection in index cases in all 11 SEE countries was travel-related with Italy being a source country for 8/11 countries. After the first case identifications on February 25, the number of cases in SEE countries is continually rising reaching the total number of 15,612 with 565 fatal cases and overall case fatality ratio (CFR) of 3.6 (median 3.8, range 0.8-5.5) by April 10, 2020. At a time when the COVID-19 pandemic is approaching its peak, apart from the problems with treatment of the disease and care for critically ill patients, there are other equally important problems, such as organization of outbreak response, provision of health care, lack of hospital personnel, disruption of personal protective equipment supply chains and health care workers (HCWs) protection. But what is more important is the heroic behavior of the HCWs who are showing their humanity by disregarding their lives.
Congenital HCMV infection is a leading infectious cause of long‐term neurodevelopmental sequelae. Infection of newborn mice with mouse cytomegalovirus (MCMV) intraperitoneally is a well‐established ...model of congenital human cytomegalovirus infection, which best recapitulates the hematogenous route of virus spread to brain and subsequent pathology. Here, we used this model to investigate the role, dynamics, and phenotype of CD8+ T cells in the brain following infection of newborn mice. We show that CD8+ T cells infiltrate the brain and form a pool of tissue‐resident memory T cells (TRM cells) that persist for lifetime. Adoptively transferred virus‐specific CD8+ T cells provide protection against primary MCMV infection in newborn mice, reduce brain pathology, and remain in the brain as TRM cells. Brain CD8+ TRM cells were long‐lived, slowly proliferating cells able to respond to local challenge infection. Importantly, brain CD8+ TRM cells controlled latent MCMV and their depletion resulted in virus reactivation and enhanced inflammation in brain.

The aim of this research was to determine the seroprevalence of Toxoplasma gondii in Bosnia and Herzegovina, with special reference to women of reproductive age in Bosnia and Herzegovina.
The ...retrospective cross-sectional study included 3685 participants tested at the Department of Microbiology and Molecular Diagnostics, University Clinical Hospital, Mostar in the period from January 1, 2010 to December 31, 2019. The detection of IgG and IgM antibodies to T. gondii was based on the enzyme immunofluorescence test.
In this study the total IgG prevalence of T. gondii was 18.7%, while only 1.7% were IgM positive. The IgG prevalence increased according to age of participants from 1.8% in 1–5 age group to 46.8% in participants older than 65 (p < 0.001). Out of total IgG positive participants, 62.8% came from rural areas (p < 0.001). An increased age (OR = 2.233) and rural residence (OR = 1.468) were found as risk factors for toxoplasmosis, whereas gender was not (OR = 1.021). Out of total 1514 women of reproductive age tested, the IgG prevalence of T. gondii was 15.8%, and IgM antibodies was present in 1.6% examined women.
This study showed a seroprevalence of T. gondii in Bosnia and Herzegovina, not only among the general population, but also among women of reproductive age. Results of the study suggest the need for more systematic preventive monitoring of pregnant women and preconception counselling for women of reproductive age.
This study explores the correlation between immunological and clinical characteristics in coronavirus disease 2019 (COVID-19) patients with detectable severe acute respiratory syndrome coronavirus 2 ...(SARS-CoV-2) RNA in feces, analyzing data from 251 patients admitted to Mostar University Clinical Hospital from December 2021 to January 2022. Methods involved reverse transcription quantitative polymerase chain reaction (RT-qPCR) from nasopharyngeal swabs and feces, alongside serological tests for anti-SARS-CoV-2 spike IgGs. Demographic and clinical data were collected through questionnaires and medical records. The data analyses were performed using SPSS statistical software. Death occurred in 53 patients (21.1%, P < 0.001), mostly in the elderly (47/53, 88.7%, P = 0.001) and immunocompromised (19/53, 35.8%, P = 0.05), particularly those developing acute respiratory insufficiency (ARI) (46/53, 86.8%, P = 0.004), and severe/critical disease (46/53, 86.8%, P = 0.002). Among the patients with positive anti-SARS-CoV-2 IgG antibodies (86/251, 34.3%, P < 0.001), 41 (47.7%) were vaccinated and 45 (52.3%) unvaccinated (P = 0.666), showing no significant differences in clinical outcomes or mortality. Unvaccinated patients with a negative antibody titer had a higher incidence of ARI (96/123, 78%, P = 0.029) and intensive care unit admission (22/123, 17.9%, P = 0.026), than those with a positive antibody titer. Forty-seven (62.7%) patients, out of the 75 hospitalized who provided a feces sample, were positive for SARS-CoV-2 RNA (P = 0.028), without statistical differences between fecal SARS-CoV-2 positive and negative groups regarding vaccination status (15/47, 31.9%, P = 0.493), antibody status (18/47, 38.3%, P = 0.628) or death outcome (5/47, 10.6%, P = 0.706). In conclusion, unvaccinated hospitalized patients with a severe COVID-19 presentation and a negative anti-spike SARS-CoV-2 IgG titer had adverse outcomes more frequently. This suggests cautious consideration for the diagnostic use of fecal samples compared to nasopharyngeal swabs.
