Background: Depression and anxiety are prevalent issues amongst individuals suffering from thoracic cancer. Gender differences in coping with thoracic cancer have a serious impact upon the management of emotional distress. The purpose of our study has been to assess sex variations in handling anxiety and depression, including the use of coping mechanisms and their relationship with respect to anxiety and depression. Methods: This cross-sectional study registered 18 women and 22 men with non-metastatic lung cancer and operated upon. Pre-operatively and at one month post-operatively, the patients were assessed by means of scales (COPE, GAD-7 and PHQ-9). Results: Post-operatively, the intensity of depression and anxiety was substantially greater in males than in females (p = 0.049, p = 0.042). Male individuals tended to use coping mechanisms of humour (p = 0.009) and restraint (p = 0.029) significantly more frequently than women. Moreover, in women, depression correlated significantly with denial and behavioural deactivation (rho = 0.465, p = 0.029, respectively, rho = 0.562, p = 0.006); whilst anxiety, similarly, correlated with positive interpretation, behavioural deactivation, and use of social-emotional support (rho = 0.484, p = 0.022, respectively, rho = 0.590, p = 0.004 and rho = 0.502, p = 0.017). Furthermore, in males, depression correlated significantly with mental deactivation, use of social-instrumental and social-emotional support (rho = 0.702, p = 0.001, respectively, rho = 0.505, p=0.033, and rho = 0.773 with p < 0.001), whilst anxiety correlated significantly with mental deactivation, denial, and use of social-emotional support (rho = 0.597, p = 0.009, respectively, rho = 0.553 with p = 0.017 and rho = 0.755, p < 0.001). Conclusion: There were gender divergences in the use of coping mechanisms and the level of post-surgical anxiety and depression. We found significant positive relationships between some coping mechanisms and depression/anxiety. The patient’s gender governs the coping style, which in turn has bearing upon the post-operative evolution.

This study aims to compare the epidemiological, clinical, and laboratory aspects of cystic echinococcosis (CE) in children with those of adults from western Romania, and to determine the specifics of this disease in the younger population. The medical records of the patients diagnosed with CE and hospitalized during 2004–2010 in four western Romanian counties were retrospectively investigated. Overall, 82 children (mean age, 10.8 years) and 369 adults (mean age, 48 years) were diagnosed with CE during the study period. The yearly detection rate was 3.1/100,000 children and 3.4/100,000 adults. The incidence rate registered a peak in children aged 5–14 years (4.4/100,000) and adults aged 60–69 years (5/100,000). Female to male ratio was 1.6:1 in pediatric cases and 1.2:1 in adults. CE was almost twice more frequent in rural areas (4.4/100,000 children and 4.9/100,000 adults) as compared to urban regions (2.3/100,000 children and 2.6/100,000 adults). Hepatic cysts were found more frequently than pulmonary cysts, at a ratio of 3.6:1 in children and 12.8:1 in adults. Most of the cases had no complications (91.5% of children and 87% of adults). Children had higher eosinophil count (7%) and erythrocyte sedimentation rate (ESR) (29.7 mm/h) as compared with adults (eosinophil count, 5.3%, p<0.001; ESR, 22.4 mm/h, p=0.001). The active transmission of the parasite in western Romania is demonstrated by the high incidence of CE in children. Long-term prevention of this disease may be reached through joined legislative efforts focused on the registration of dogs, home slaughter of sheep and swine, veterinary control in abattoirs, destruction of infected materials, and restriction of dogs' access to vegetable gardens and children's parks.

Stress, anxiety, and post-surgical chest pain are common problems among patients with thoracic surgical pathology. The way in which psychological distress is managed—the coping style—can influence the postsurgical evolution and quality of life of patients. In our study, we monitored the influence of coping style on patients’ anxiety and the intensity of post-operative chest pain. We conducted a cross-sectional study on 90 subjects with thoracic surgical pathology. One month after their surgeries, patients completed the following scales and questionnaires, translated, adapted, and validated for the Romanian population: COPE scale inventory, Generalized Anxiety Disorder-7 Questionnaire, McGill Pain Questionnaire, and Numeric Pain Rating Scale. Anxiety (evaluated using the Generalized Anxiety Disorder-7 Questionnaire) and postoperative thoracic pain intensity (evaluated by means of the Numeric Pain Rating Scale, Number of Words Chosen, and McGill Pain Questionnaire) were significantly higher in patients exhibiting social-focused coping than in patients presenting emotion-focused or problem-focused coping as their main coping style (Kruskal–Wallis, p = 0.028, p = 0.022, p = 0.042, p = 0.007). In our study, there were no differences observed in pain intensity relative to level of anxiety. Coping style is an important concept in the management of anxiety and pain experienced by patients undergoing chest surgery. Therefore, a multidisciplinary approach should be considered in clinical practice.

Quercetin is a natural flavonoid renowned for its potent antioxidant, anti-inflammatory, anti-diabetic, and antibacterial properties, making it a highly promising candidate for the treatment of various medical conditions. Our current study investigates the influence of quercetin on energy metabolism, fatty acid composition, oxidative stress gene expression, and sirtuin expression in early- and late-stage passages of stem cells derived from human exfoliated deciduous teeth (SHEDs). Mitochondrial respiration was analyzed by measuring oxygen consumption following a 24 h quercetin treatment, while fatty acid profiles were examined using gas chromatography–mass spectrometry (GC-MS). Additionally, quantitative PCR (qPCR) was used to assess the expression of oxidative stress genes and sirtuins. In younger SHEDs, quercetin enhances metabolic activity and mitochondrial respiration, although higher doses may decrease mitochondrial activity. Conversely, in older, senescent SHEDs, quercetin supports mitochondrial function at lower concentrations but appears to inhibit respiration at higher doses. These results suggest that quercetin may hold therapeutic potential for maintaining SHED viability and function, especially at lower doses in older cells. Further research is essential to fully elucidate a dose-dependent effect of quercetin and optimize its applications in regenerative medicine.

Summary: Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are considered as one of the most important zoonotic diseases in Romania, where they are subject to mandatory reporting. To obtain more knowledge about the genetic diversity of Echinococcus causative agents of these diseases, 11 isolates from humans and ungulate intermediate hosts from the two regions of Romania were genotyped using mitochondrial markers. In clinical samples of five patients from north-eastern Romania (Iasi, Botosani, Vaslui counties), Echinococcus multilocularis was identified as causal agent by cox1 sequence analysis. To the best of our knowledge this finding presents the first molecular evidence of E. multilocularis in humans from Romania. Only two cases of AE in patients were previously documented in the country by serological methods. In our four patients the most widespread European variant E5 of E. multilocularis was recorded, whereas in isolate from Vaslui county three nucleotide substitutions were detected as compared to the most related E5 haplotype. One of these mutations (411T/G) matched N1 and N2 haplotypes described previously from North America. In six CE samples retrieved from western Romania (Caras-Severin and Timis counties), two human isolates were diagnosed as Echinococcus canadensis G7, one as E. granulosus s.s. G1 and one as E. granulosus s.s. G3 using atp6 and rrnS sequencing. In ungulates, the cattle isolate was allocated to E. granulosus s.s. G1 and pig isolate to E. canadensis G7. The two G7 findings in humans reinforced the recent view that G7 was underestimated as compared to the E. granulosus s.s. regarding human CE threat that can be further employed for identifying sources of infections and establishing suitable preventive measures.

Aristolochic acids, compounds derived from Aristolochiaceae plant species, are associated with significant renal nephrotoxicity and carcinogenicity. Aristolochic acid I (AAI), the most predominant and potent of these compounds, is a primary etiological agent in acute and chronic kidney diseases such as Aristolochic Acid Nephropathy (AAN) and Balkan Endemic Nephropathy (BEN). Due to the kidneys’ critical role in xenobiotic excretion, they are the primary organs affected by AAI toxicity. Recent in vitro and in vivo studies have highlighted mitochondrial dysfunction as a crucial factor in the pathogenesis of these kidney diseases. This review provides an update on the recent advances in understanding the causes of acquired mitochondrial dysfunction within the context of AAN and BEN. Key findings include the identification of mitochondrial DNA depletion, loss of mitochondrial membrane potential, and decreased ATP production as significant contributors to kidney damage. Additionally, oxidative stress markers and inflammatory mediators have been implicated in disease progression. Potential therapeutic approaches, such as the use of antioxidants like vitamin C and catalpol, have shown promise in mitigating AAI-induced cytotoxicity. Furthermore, future predictive approaches like pharmacogenomics could pave the way for novel mitochondria-targeted treatments. A comprehensive characterization of mitochondrial function, its underlying molecular mechanisms, and specific biomarkers could offer valuable insights and potential therapeutic options, significantly impacting the current management of AAN and BEN.
