Coordinated activation of sympathetic and respiratory nervous systems is crucial in responses to noxious stimuli such as intermittent hypoxia. Acute intermittent hypoxia (AIH) is a valuable model for studying obstructive sleep apnea (OSA) pathophysiology, and stimulation of breathing during AIH is known to elicit long-term changes in respiratory and sympathetic functions. The aim of this study was to record the renal sympathetic nerve activity (RSNA) and phrenic nerve activity (PNA) during the AIH protocol in rats exposed to monoanesthesia with sevoflurane or isoflurane. Adult male Sprague-Dawley rats (n = 24; weight: 280–360 g) were selected and randomly divided into three groups: two experimental groups (sevoflurane group, n = 6; isoflurane group, n = 6) and a control group (urethane group, n = 12). The AIH protocol was identical in all studied groups and consisted in delivering five 3 min-long hypoxic episodes (fraction of inspired oxygen, FiO2 = 0.09), separated by 3 min recovery intervals at FiO2 = 0.5. Volatile anesthetics, isoflurane and sevoflurane, blunted the RSNA response to AIH in comparison to urethane anesthesia. Additionally, the PNA response to acute intermittent hypoxia was preserved, indicating that the respiratory system might be more robust than the sympathetic system response during exposure to acute intermittent hypoxia.

COVID-19 vaccine uptake in the Federation of Bosnia and Herzegovina (FBiH) accelerated in the second half of 2021, with greater vaccine availability. In this study, we estimated the vaccine effectiveness (VE) of complete primary series BBIBP-CorV vaccine against COVID-19 in patients aged 60 years and older, during the Delta-dominant period, using a test-negative case-control design. Surveillance sites were 11 primary health care centers (PHC) collecting patient data from October 1, 2021, to January 4, 2022, retrospectively according to a common protocol. In total, we included 1711 participants in the analysis: 933 cases and 778 controls. Of the 933 cases, 508 (54.4 %) had mild and 425 (45.6 %) had moderate to severe disease presentation. We observed no effectiveness against mild COVID-19. Overall vaccine effectiveness was 65.0 % (95 %CI: 40.1-79.5) against moderate to severe COVID-19. In time since vaccination analysis, VE was 78.7 % (95 % CI: 54.8-89.9) in patients who received their last dose < 90 days before onset; 66.0 % (95 % CI: -0.5-88.5) in those 90-119 days before onset; 42.1 % (95 % CI: -88.6-82.3) in those 120-149 days before onset and 45.0 % (95 % CI: -94.0-84.4) in those ≥ 150 days before onset. In our study, two doses of BBIBP-CorV provided considerable protection against moderate to severe COVID-19 in older adults, highest within 3 months after second dose, during the Delta-dominant period. Point estimates declined thereafter, suggesting a need for additional doses.

BACKGROUND The aim of the study was to assess socio-demographical characteristics, clinical presentation, and outcomes in patients diagnosed with mpox. METHODS A survey on patients diagnosed with mpox was performed in 14 countries from Central and Eastern Europe. Data was compared according to HIV status and country of origin (EU vs. non-EU). Mpox diagnosis was confirmed by RT-PCR from oropharyngeal swabs, skin lesions, and other body fluids. RESULTS Out of 154 patients confirmed with mpox in 2022, 99.3% were males, with a median age (years) of 35 (IQR 30-39), 90.2% MSM and 48.7% PLWH.Compared to HIV-negative subjects, PLWH had more frequent high-risk behaviours:chemsex (p = 0.015), group sex (p = 0.027), and a history of sexually transmitted infections (STIs) (p = 0.004). Persons from EU were more often PLWH (p = 0.042), MSM (p < 0.0001), had multiple sexual partners (p = 0.025), practiced chemsex (p = 0.008) or group-sex (p = 0.005) and had more often history of STIs (p < 0.0001). The median CD4 cell count/mL at mpox diagnosis was 713 (IQR 486-996) and 73.5% had undetectable HIV VL. The commonest clinical features were fever (108 cases), lymphadenopathy (78), and vesiculo-pustular rash: penile (76), perianal (48), limbs (67). Fifty-one (31%) persons were hospitalized due to complications or epidemiological reasons. Three patients received tecovirimat or cidofovir. The outcome was favorable for all patients, including 4 with severe forms. CONCLUSIONS Mpox was diagnosed predominantly in young MSM, with high-risk behaviors and history of STIs. Effective contact tracing and vaccination are important strategic pillars to control mpox outbreaks.

Introduction: There are concerns with rising rates of antimicrobial resistance (AMR) across countries with appreciable impact on morbidity, mortality and costs. Amongst low- and middle-income countries, a key driver of AMR is the excessive use of antibiotics in ambulatory care, with a critical area being the appreciable selling of antibiotics without a prescription often driven by patient demand and limited knowledge. There is currently conflicting evidence in South Africa regarding this practice. Consequently, there is a need to explore these critical issues amongst patients, especially in more rural areas of South Africa. A pilot study was undertaken to address this. Methods: A two-step descriptive approach was undertaken. This involved two questionnaires amongst patients exiting chain and independent community pharmacies followed by cognitive interviews. Results: Overall, 21 patients were approached for an interview, including 11 for Part 1 of the questionnaire with 3 declining, and 10 for Part 2, with 2 declining. Subsequently 8 patients completed each part of the questionnaire.. On average, it took 2 min 13 s to complete both parts. 3 of the 5 patients being dispensed an antibiotic were dispensed one without a prescription, with all 3 patients exiting from independent pharmacies. Key reasons for self-purchasing included money and convenience. There was mixed knowledge regarding antibiotics and AMR amongst the 8 patients interviewed with Part 2. Overall, there was a satisfactory understanding of the Part 1 questions, although some modifications were suggested. Some participants had difficulty with fully understanding the questions in Part 2, with a number of suggestions made to improve this for the main study. Conclusion: There were concerns with the extent of purchasing antibiotics without a prescription in this pilot study as well as the knowledge of patients regarding antibiotics and AMR. Both areas need addressing and will be explored further in the main study.

Biomonitoring of human populations exposed to chemical substances that can act as potential mutagens or carcinogens, may enable the detection of damage and early disease prevention. In recent years, the comet assay has become an important tool for assessing DNA damage, both in environmental and occupational exposure contexts. To evidence the role of the comet assay in human biomonitoring, we have analysed original research studies of environmental or occupational exposure that used the comet assay in their assessments, following the PRISMA-ScR method (preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews). Groups of chemicals were designated according to a broad classification, and the results obtained from over 300 original studies (n = 123 on air pollutants, n = 14 on anaesthetics, n = 18 on antineoplastic drugs, n = 57 on heavy metals, n = 59 on pesticides, and n = 49 on solvents) showed overall higher values of DNA strand breaks in the exposed subjects in comparison with the unexposed. In summary, our systematic scoping review strengthens the relevance of the use of the comet assay in assessing DNA damage in human biomonitoring studies.

Aim This study aimed to assess the impact of forced repeated swimming stress on serum adiponectin and endothelin-1 levels in Wistar rats, comparing the effects between those fed a standard diet and those on a high-fat diet. Methods Twenty adult male Wistar rats were divided into two dietary groups: a standard food diet group (NFD, n=10) and a high-fat diet group (HFD, n=10). Both groups underwent daily forced swimming stress for six days, with durations increasing from 5 to 30 minutes. The protocol finished in an acute bout of swimming exercise on the seventh day with a duration of 40 minutes. Adherence to ethical guidelines was strictly maintained, and serum adiponectin and endothelin-1 levels were measured pre- and post-exercise using the ELISA method. Results Before swimming, the mean adiponectin levels were 4.30±1.50 ng/mL in the NFD group and 3.53±0.70 ng/mL in the HFD group. Post-exercise, these levels significantly decreased to 2.4±0.84 ng/mL (p=0.003) and 1.58±0.23 ng/mL (p=0.001), respectively. Endothelin-1 levels also showed significant decreases from 0.86 pg/mL (0.74-0.87) to 0.49 pg/mL (0.43-0.62) (p=0.003) in the NFD group, and from 0.89 pg/mL (0.86-0.93) to 0.69 pg/mL (0.60-0.75) (p=0.027) in the HFD group after swimming. Conclusion The study highlighted the significant effects of forced swimming stress on lowering serum adiponectin and endothelin-1 levels in Wistar rats, with more pronounced decreases observed in rats on a high-fat diet. The results of the study suggest the potential of exercise as a crucial component of strategies aimed at managing obesity and improving cardiovascular health, emphasizing the interaction between physical stress and dietary factors on metabolic and cardiovascular biomarkers.

In addition to their undeniable importance for industry, natural plant products are widely used in the production of functional food, which, in addition to satisfying nutritional properties, also exhibits certain pharmacological and physiological effects on human health. Chokeberryfruit and products are considered to be excellent sources of polyphenoliccompounds. A large part of polyphenolic compounds from aronia berriesis found in the juice, but the flesh of the berry that remains behind in the juice production process is also richin these bioactive compounds. The aim of the conducted research was to examine the antioxidant potentialof thechokeberry juices from Bosnia and Herzegovina.The antioxidant potentialof chokeberryjuicesin this study wastestedbythe ferric reducing antioxidant power(FRAP)andtotal phenol content (FC). Tests were carried out in other juices for the same parameters in order to compare the obtained values.The research results show that the values of FRAP and total phenols in chokeberry juices vary (20-63 mmol Fe II/L; 850-4930 mgGAE/L), but are significantly higher than in other analyzed juices (7-25 mmol FeII/L; 220–1265 mgGAE/L). By comparing the content of total phenols and FRAP values in pasteurized and unpasteurized chokeberry juice samples, it can be concluded that they are higher in the sample prepared by the pasteurization process. Statistical parameters showthat thelinearcorrelation between thetotal phenols and the FRAP valuesof chokeberry juices (r=0,964; p ˂0,001) and other analysedjuices (r=0,960;p ˂0,001 ) isstatisticallysignificant.

This study aimed to investigate the cytotoxic activity of decidual lymphocytes and the mRNA/protein expression of cytotoxic proteins in various cell types in the context of preeclampsia (PE) compared to those of healthy pregnancies. We analyzed fresh decidua basalis tissue and tissue embedded in paraffin (FFPE) from PE pregnancies (n = 15) and compared them with those of healthy pregnancies (n = 15) of the corresponding gestational age. Using double immunofluorescence staining, we observed differences in the intensity and distribution of staining for granzyme K (GZMK) and FasL in extravillous trophoblasts. RT-qPCR analysis of FFPE placental tissue showed that GZMK mRNA expression was statistically higher (p < 0.0001) in PE compared to that of healthy controls. On the contrary, there was a low expression (p < 0.001) of FasL mRNA in PE compared to controls, while there was no statistically significant difference for IFN-γ mRNA between PE and controls. Although the level of cytotoxic activity changed depending on the ratio of effector and target cells, there was no significant difference observed between PE and controls in this in vitro study. In conclusion, in PE, extravillous trophoblasts exhibited increased expression of GZMK and decreased expression of FasL. These changes may contribute to impaired trophoblast invasion. However, these alterations did not appear to affect the cytotoxic properties of decidual lymphocytes. Additionally, the possibility of cell sorter separation of decidual lymphocytes would greatly contribute to a better understanding of single cells’ genetic profiles.

The chemical composition of Pulicaria dysenterica(L.) Bernh. aerial parts essential oil (EO), growing wildin Bosnia and Herzegovina, was presented in the study. In addition to the EO composition, antimicrobial and cytotoxic activities were also tested. The aerial parts of P. dysentericacontained 0.3% of yellow, liquid, fragrant EO. The 51 components identified accounted for 81.09% of the oil. The EO was characterized by the presence of a high concentration of oxygenated sesquiterpenes 51.83% while oxygenated monoterpenes constituted 15.57%, sesquiterpene hydrocarbons 9.32% and non-terpene compounds presented 4.37% of the EO. The dominant compounds were the sesquiterpenes caryophyllene oxide, (E)-nerolidol, β-caryophyllene and monoterpene nerol. The antimicrobial activity of EO was tested against selected ATCC strains of microorganisms, the bacteria Staphylococcus aureus, Pseudomonas aeruginosaand Escherichia coli, and the fungus Candida albicans. The results showed that the investigated EO inhibited the growth of all selected ATCC strains of microorganisms. The best result was obtained against Escherichia colibacteria with MIC value of 1 mgmL-1. The cytotoxicity of EO was measured against the HeLa cell line using the MTT method with IC50of 188.52 μgmL-1.This study has provided scientific baseline data on the therapeutic properties of P. dysenterica.

Toxicity caused by carbon tetrachloride (CCl4) can lead to serious liver injury. The aim of the study is to investigate the protective effects of oregano oil (Origanum minutiflorum extract oil) against CCl4‐induced liver injury. Two doses of oregano oil were used in the experiment: a low dose (LD; 20 mg/kg) and a high dose (HD; 60 mg/kg) during 2 weeks. CCl4 caused severe liver damage, nucleolus destruction in hepatocytes and cytogenetic changes in the nucleus. Indirectly, CCl4 causes decreased protein synthesis and significantly high creatinine and urea values. Hematological disorders have been recorded, such as decreased RBC and hemoglobin concentration, increased WBC and deformability of the erythrocyte membrane. Both doses of oregano oil had protective effects. Improved protein synthesis and high globulins level, creatinine and urea were found in both groups. Cytogenetic changes in the nucleus of hepatocytes were reduced. A high dose of oregano oil had maximal protective effects for RBC, but a very weak effect on hemoglobin synthesis. Also, WBC and lymphocyte values were low. Origanum stimulates protein synthesis and recovery of hepatocytes after liver injury, reduces the deformability of the erythrocyte membrane. High doses of oregano oil decreased WBC and lymphocytes which may lead to a weakening of the immune response. However, high doses are more effective against severe platelet aggregation than low doses, suggesting an effective treatment against thrombocytosis.

Public budgeting and finance is a discipline that encompasses communities of research and practice. Too often, however, these communities fail to engage each other, instead choosing to operate independently. The result is that the research being conducted fails to address the questions of the day and our governments’ challenges. In this article, we come together as a community of academics and practitioners to establish an agenda for where future research should be conducted. This agenda aims to align the research being undertaken within the academic community with the needs of those working in the community of practice. After establishing ten areas where research is needed, we followed a ranked-choice voting process to establish a prioritization for them. Based on the outcome of this process, the two primary areas where research is currently needed most are the fiscal health of our governments and the implementation of social equity budgeting.  

Simple Summary The aim of this study was to analyze and compare the morphology of root canals in the carnassial teeth of German shepherds and mixed-breed dogs. Knowledge of the morphology of root canals is essential for a successful endodontic procedure. It has been determined that an apical delta, which represents a complex structure that consists of multiple cavities whose purpose is to allow the passing of nerves and blood vessels from the pulp cavity to the apex of the root, was present in 247 roots. There are four main types of apical delta. The most common type in superior fourth premolars was type II, with up to 10 apical ramifications, whereas type IIIA, with 10–20 apical ramifications, was most commonly present in inferior first molars. Abstract Root canal treatment of carnassial teeth in dogs is a common endodontic technique which aims to re-establish or maintain the health of the periapical tissues. In total, 43 dogs were used in this study. Root canal morphology was evaluated in 86 superior fourth premolars and 86 inferior first molars. Apical delta was present in 247 roots, while obliteration of the root canal was found in 11 roots. The most common type of apical delta of the roots of superior fourth premolars was type II, with up to 10 apical ramifications, while type IIIA, with 10–20 apical ramifications, was most commonly present in the roots of inferior first molars. Considering that knowledge of the morphology of root canals is essential for a successful endodontic procedure, the aim of this study was to analyze and compare the morphology of root canals in the carnassial teeth of German shepherds and mixed-breed dogs. Apical resection for the purpose of endodontic therapy of the superior fourth premolar and the inferior first molar is indicated at a length of 4 to 6 mm from the anatomical tip of the roots, which would completely remove the apical delta of these two teeth.
