Environmental microbiome diversity and stability is a barrier to antimicrobial resistance gene accumulation.

When antimicrobial resistant bacteria (ARB) and genes (ARGs) reach novel habitats, they can become part of the habitat's microbiome in the long term if they are able to overcome the habitat's biotic resilience towards immigration. This process should become more difficult with increasing biodiversity, as exploitable niches in a given habitat are reduced for immigrants when more diverse competitors are present. Consequently, microbial diversity could provide a natural barrier towards antimicrobial resistance by reducing the persistence time of immigrating ARB and ARG.

Restricted Mean Survival Time-Can It Be a New Tool in Assessing the Survival of Non-Small Cell Lung Cancer Patients Treated with Immune Checkpoint Inhibitors?

Background: Lung cancer (LC) is the first and most lethal cancer in the world; identifying new methods to treat it, such as immune checkpoint inhibitors (ICIs), is needed. ICIs treatment is very effective, but it comes bundled with a series of immune-related adverse events (irAEs). Restricted mean survival time (RMST) is an alternative tool for assessing the patients' survival when the proportional hazard assumption (PH) fails.

The Bidirectional Relationship between Pulmonary Tuberculosis and Lung Cancer.

Lung cancer and pulmonary tuberculosis are two significant public health problems that continue to take millions of lives each year. They may have similar symptoms and, in some cases, are diagnosed simultaneously or may have a causal relationship. In tuberculosis disease, the chronic inflammation, different produced molecules, genomic changes, and fibrosis are believed to be important factors that may promote carcinogenesis.

Studies Regarding the Antimicrobial Behavior of Clotrimazole and Limonene.

The paper presents the results of the studies performed to establish the effect of the mixtures between limonene and clotrimazole against microbial pathogens involved in dermatological diseases, such as , , and . Preliminary data obtained from the studies performed in microplates revealed a possible synergism between the mixture of clotrimazole and limonene for . Studies performed "in silico" with programs such as CLC Drug Discovery Workbench and MOLEGRO Virtual Docker, gave favorable scores for docking each compound on a specific binding site for each microorganism.

Barriers and Facilitators of Romanian HPV (Human Papillomavirus) Vaccination.

Background: Many countries had initial success with HPV vaccination campaigns worldwide. The HPV vaccine coverage during the COVID-19 pandemic dropped consistently. The aim of our research is to assess the barriers and facilitators of the current Romanian HPV vaccination campaign.

Romania, a Harbour of HIV-1 Subtype F1: Where Are We after 33 Years of HIV-1 Infection?

Infection with the human immunodeficiency virus (HIV) has been a major public health concern worldwide for more than 30 years, including in Romania. The F1 HIV-1 subtype was exported from Angola to Romania most probably because of the two countries' close political connections. Patients infected with HIV-1 via re-used and improperly sterilized injection equipment and through transfusions of unscreened blood, also known as the "Romanian cohort", were the most common type of HIV-1 infection in Romania in the early 1990s, when the virus's presence was recognized.

Obtaining and Characterizing Composite Biomaterials of Animal Resources with Potential Applications in Regenerative Medicine.

Raw materials, such as collagen and chitosan, obtained from by-products from the food industry (beef hides and crustacean exoskeletons), can be used to obtain collagen-chitosan composite biomaterials, with potential applications in regenerative medicine. Functionalization of these composite biomaterials is a possibility, thus, resulting in a molecule with potential applications in regenerative medicine, namely clotrimazole (a molecule with antibacterial, antifungal, and antitumor activity), at a mass ratio (collagen-chitosan-clotrimazole) of 1:1:0.1.

Studies Regarding the Pharmaceutical Potential of Derivative Products from .

In this study, three types of extracts isolated from leaves of Plantain () were tested for their chemical content and biological activities. The three bioproducts are combinations of polysaccharides and polyphenols (flavonoids and iridoidic compounds), and they were tested for antioxidant, antifungal, antitumor, and prebiotic activity (particularly for polysaccharides fraction). Briefly, the iridoid-enriched fraction has revealed a pro-oxidant activity, while the flavonoid-enriched fraction had a high antioxidant potency; the polysaccharide fraction also indicated a pro-oxidant activity, explained by the co-presence of iridoid glycosides.

Coronasomnia in Employees without a Direct Contact with COVID-19 Infected Patients in Their Workplace.

Background: The aim of this analysis was to explore coronasomnia in second line workers.

Methods: Data were collected via in an online questionnaire. Patients with new onset or aggravation of insomnia were defined as cases and those without insomnia as controls.

COVID-19 Parental Vaccine Hesitancy in Romania: Nationwide Cross-Sectional Study.

Background: COVID-19 vaccination started in Romania in December 2020. Child vaccination started in 2021 with children aged 12-15 years in August. For children aged 5-11 years, vaccination started in January 2022.

Emergence of SARS-CoV-2 Alpha lineage and its correlation with quantitative wastewater-based epidemiology data.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) gave rise to an international public health emergency in 3 months after its emergence in Wuhan, China. Typically for an RNA virus, random mutations occur constantly leading to new lineages, incidental with a higher transmissibility. The highly infective alpha lineage, firstly discovered in the UK, led to elevated mortality and morbidity rates as a consequence of Covid-19, worldwide.

Resilience of agricultural soils to antibiotic resistance genes introduced by agricultural management practices.

Antimicrobial resistance (AR) represents a global threat in human and veterinary medicine. In that regard, AR proliferation and dissemination in agricultural soils after manure application raises concerns on the enrichment of endogenous soil bacterial population with allochthonous antibiotic resistance genes (ARGs). Natural resilience of agricultural soils and background concentrations of ARGs play key roles in the mitigation of AR propagation in natural environments.

Ciprofloxacin-Collagen-Based Materials with Potential Oral Surgical Applications.

We report in this paper the synthesis and characterization of a new collagen-based material. This material was obtained in a spongy form and was functionalized with an antibiotic, ciprofloxacin. The targeted applications of these kind of materials concern the post-operative prophylaxis.

Cloning and expression of the L1 major capsid protein of the human papillomavirus 18 in murine cells.

Human papillomavirus (HPV) type 18 is strongly associated with the development of cervical cancer. Studies of a model system with animal papillomaviruses have demonstrated the importance of neutralizing antibodies in preventing papillomavirus-associated disease. The immune response to HPV is poorly understood, and there are non- standardized serological assays to identify HPV infections.

The evidence of circulation of some viruses in a great town of Romania during the first half of 1992.

Complex serological survey performed in the town B. during the first half of 1992 emphasized an active circulation of some respiratory viruses, especially of parainfluenza type 3 and 1, influenza subtypes A(H3N2) and A(H1N1), adeno and syncytial respiratory as well as of Mycoplasma pneumoniae. Less important was the frequence of antibodies against Chlamydia psittaci, East equine, West Nile and tick-borne encephalitis as well as parainfluenza type 2 and influenza type B viruses.
