Therapeutic Use of Some Romanian Medicinal Plants
Romanian traditional medicine has an extremely old history. The Dacian knowledge of the curative properties of medicinal plants was documented by Herodotus, Hippocrates, Galen, and Dioscorides. It must be emphasized that modern chemical screening has confirmed the therapeutic properties of the medicinal plants used by the Dacians. More interesting is that Dacians used many of these herbs for different dishes. Practically, for Dacians, food was medicine. Recent research on some Romanian medicinal plants has highlighted their pharmacognostical importance. It is known that currently, the importance and dynamics of the research on medicinal plants in the area of drug discovery continues to increase worldwide. The main reason is not only the high efficiency of secondary metabolites in case of serious diseases (cancer, viral infections, malaria, etc.) but also the minimization of the side effects of the synthetic drugs
Retrospective Analysis of Vitamin D Deficiency in an Adult Population of Arad County, Western Romania (2019â2022)
Vitamin D, a steroid hormone synthesized primarily in the skin upon exposure to ultraviolet light, is widely deficient across global populations. This study aimed to fill the data gap in Western Romania by measuring 25-hydroxy-vitamin D levels in a cohort of 7141 from Arad County. It was observed that women, younger adults (18â29 years), and older adults (70â79 years) had notably lower vitamin D levels compared to the average population. Additionally, there was a rise in vitamin D levels over the four-year span of 2018â2022, coinciding with the COVID-19 pandemic. Our research provides fresh data on those most susceptible to vitamin D deficiency and lays the groundwork for educational campaigns on vitamin D supplementation benefits
Screening for the Detection of <i>Toxoplasma gondii</i> IgG, IgM and IgA in Females of Reproductive Age from Western Romania
Toxoplasma gondii, a zoonotic protozoan parasite, has the capacity to infect the fetus if the pregnant woman primarily acquires the infection during pregnancy. We evaluated the prevalence of T. gondii IgG, IgM and IgA antibodies in women of reproductive age residing in Western Romania. We also assessed the value of adding a T. gondii IgA test to the serologic panel for the diagnosis of toxoplasmosis, including the detection of a recently acquired infection. Serologic testing to demonstrate the presence of T. gondii IgG antibodies was conducted in 1317 females aged 15â45 years. T. gondii IgM and IgA antibody tests were performed in those with detectable IgG antibodies and IgG avidity test was performed if IgM and/or IgA screening test results were positive. T. gondii IgG were detected in 607 (46.09%; 95%CI: 43.41â48.79) of 1317 study participants and IgG seroprevalence tended to increase with age from 35.44% (95%CI: 29.89â41.30) in age group 15â24 years to 62.85% (95%CI: 56.57â68.82) in age group 35â45 years, showing a significant age-associated increase (p T. gondii IgG antibodies, T. gondii IgM antibodies were demonstrated in 8.90% (95%CI: 6.88â11.43), T. gondii IgA in 1.65% (95%CI: 0.90â3.01) and both T. gondii IgM and IgA in 0.99% (95%CI: 0.45â2.14). The prevalence of IgA antibodies tended to decrease with increasing avidity, from 75% (95%CI: 19.41â99.37) in samples with low avidity to 11.76% (95%CI: 4.44â23.87) in those with high avidity (p = 0.01). Of the study participants who were positive for both T. gondii IgM and IgA antibodies, 66.67% had low or equivocal IgG avidity test results compared to 6.25% who tested positive for IgM, were negative for IgA and in whom low or equivocal IgG avidity test results were noted (p = 0.001). This study indicates that in Western Romania, T. gondii IgG seroprevalence is high in females of reproductive age and T. gondii IgA antibodies may be rarely detected during a serologic screening. However, in individuals with demonstrable T. gondii IgG and IgM antibodies, testing for T. gondii IgA may improve the rate for the detection of a recently acquired toxoplasmosis
Seroprevalence of
Toxoplasmosis is an important worldwide zoonosis caused by the protozoan parasite Toxoplasma gondii. This parasitic infection is often asymptomatic in immunocompetent people. However, if the infection occurs in pregnant women, it can have serious consequences for the foetus. In this study, we evaluated the seroprevalence of T. gondii in women of childbearing age in Arad County, Western Romania. Serum samples from 2626 women were analysed using a Siemens ADVIA Centaur XP Immunoassay System. Toxoplasma gondii IgG antibodies were demonstrated in 1081 women (41%) and prevalence tended to increase with age, from 32% in women aged 15â19 years to 62% in women aged 40â45 years. There was a higher prevalence in rural areas (46%) than in urban areas (36%). This study provides new data on T. gondii seroprevalence in women of childbearing age from Western Romania
A Retrospective Analysis from Western Romania Comparing the Treatment and Survivability of p16-Positive versus p16-Negative Oropharyngeal Cancer
Background: Oropharyngeal cancer is a global health concern due to its multifaceted nature. Recent molecular studies have linked p16 overexpression, associated with the human papillomavirus, to oropharyngeal cancer and its prognostic implications. Materials and Methods: This retrospective study in Western Romania examined 60 patients, categorizing them based on p16 biomarker status: 28 were p16 positive, and 32 were p16 negative. Statistical tests, including Fisherâs exact and chi2, were used for analysis. Results: Patients with p16-positive oropharyngeal cancer exhibited a better prognosis (3-year survival, p = 0.0477; midtreatment, p = 0.0349) and reported lower alcohol (p = 0.0046) and tobacco (p < 0.0001) use. Conclusions: The study highlights the importance of p16 testing in oropharyngeal carcinoma diagnosis. It suggests modifying treatment approaches based on p16 status and underscores the differing prognoses associated with p16-positive and p16-negative cases
The Effects of Vitamin D Supplementation on Respiratory Infections in Children under 6 Years Old: A Systematic Review
Childhood respiratory tract infections (RTIs) pose a significant health burden, especially in children under six years old. The main objective of this systematic review was to assess the effectiveness of vitamin D supplementation in the prevention of RTI in this population while also exploring potential effect modifiers such as age, baseline vitamin D status, and type of respiratory infection. A systematic review of the literature published up to February 2023 was conducted according to PRISMA guidelines, searching PubMed, Web of Science, Cochrane, and Scopus databases. Eight studies met the inclusion criteria, which investigated the association between vitamin D supplementation and respiratory infections in children between zero and five years old. The included studies were conducted between 2012 and 2021, encompassing a total of 2189 children from five randomized trials, two case-control studies, and one prospective cohort study. The relationship between vitamin D supplementation and the prevention of childhood RTI was not consistently observed across all included studies. Pooled results demonstrated varied effects of vitamin D supplementation on respiratory infection incidence, severity, and symptoms. Three studies reported statistically significant associations between low vitamin D levels and respiratory infections (OR = 4.90, OR = 6.97), while one study found that children who received vitamin D supplementation of 800 UI/day for 3 months during the cold season had fewer episodes of respiratory symptoms (RR = 0.55) and recovered more quickly from acute RTI. Lastly, according to one study, vitamin D intake p-value > 0.050). The available evidence on the effectiveness of vitamin D supplementation for preventing and treating respiratory infections in children under six years old is limited, with only a few favorable effects being reported. In some cases, a dose of 80 UI/kg/day was found to provide significant protection for acute respiratory infections, although in the major trials the only benefit was a quicker recovery and fewer respiratory symptoms, with no impact on incidence and severity of respiratory infections. Nevertheless, the study protocol, the supplementation dose, and duration of supplementation had significant variations between studies, leading to inconclusive findings
Plankton dynamics across the freshwater, transitional and marine research sites of the LTER-Italy Network. Patterns, fluctuations, drivers
A first synoptic and trans-domain overview of plankton dynamics was conducted across the aquatic sites belonging to the Italian Long-Term Ecological Research Network (LTER-Italy). Based on published studies, checked and complemented with unpublished information, we investigated phytoplankton and zooplankton annual dynamics and long-term changes across domains: from the large subalpine lakes to mountain lakes and artificial lakes, from lagoons to marine coastal ecosystems. This study permitted identifying common and unique environmental drivers and ecological functional processes controlling seasonal and long-term temporal course. The most relevant patterns of plankton seasonal succession were revealed, showing that the driving factors were nutrient availability, stratification regime, and freshwater inflow. Phytoplankton and mesozooplankton displayed a wide interannual variability at most sites. Unidirectional or linear long-term trends were rarely detected but all sites were impacted across the years by at least one, but in many case several major stressor(s): nutrient inputs, meteo-climatic variability at the local and regional scale, and direct human activities at specific sites. Different climatic and anthropic forcings frequently co-occurred, whereby the responses of plankton communities were the result of this environmental complexity. Overall, the LTER investigations are providing an unparalleled framework of knowledge to evaluate changes in the aquatic pelagic systems and management options
