The quality of the indoor microclimate in museums is a problem of great interest to the contemporary society, given that it is in close connection with the health and comfort of visitors and employees, as well as with the integrity of the exhibits. Taking into account the fact that museums are places that have a special role in the community’s life and therefore attract a very large number of visitors of all ages, a very important issue is to determine the degree of safety that the indoor microclimate presents. Thus, the quality of the indoor microclimate was investigated inside an iconic museum in Romania, dating back to the 19th century, because pollutants from external or internal sources of the building, generated secondary, often anthropogenic, as a tendency to defend/adapt to climate change (CC), contribute to both local and regional pollution, but also lead to challenges in identifying links between air quality (AQ) and and climate change (CC). The methodology used was based on monitoring the main parameters of the microclimate (temperature, relative humidity and CO₂) over a period of between October 2020 and March 2021, 21 weeks, as well as on determining the microbiological contamination of the air and some indoor exhibits located in three different areas of the museum. At the same time, the study aims to identify cheap, easy to implement and non-invasive solutions for removing fungi identified on exhibits for long-term preservation and reducing the risk of various pathologies in humans following prolonged exposure. The results obtained show that the indoor microclimate in the old heritage building favours the development of fungi, which have a high degree of contamination of the air (over 800 CFU/m³) and of the exhibits, representing a potential risk for the health of the visitors and museum workers. Thus, six species of yeast and five different fungi genera were identified in the air, while on the exhibits were individualised six fungi genera, a species of yeast and a bacterium. The most viable solution for cleaning materials, prolonging their lifespan and reducing the risk of disease in humans was represented by the use of essential oils (EO). Three essential oils (lavender, mint and lemon) were applied on an exhibit with five different microorganism genera, and it was observed that they have the ability to inhibit the spores from moulds and bacteria, being a very good alternative to the usual chemical treatments that are used in the cultural heritage field.

Chronic endometritis (CE) is a persistent, often asymptomatic inflammatory condition of the endometrium, increasingly recognized as a potential contributor to infertility and recurrent implantation failure. Despite its clinical significance, CE remains underdiagnosed due to a lack of standardized diagnostic criteria and its subtle clinical presentation. Objective: This review aims to synthesize the current evidence on the pathophysiology, diagnosis, and treatment of CE, highlighting its impact on reproductive outcomes and the effectiveness of therapeutic interventions. A comprehensive literature review was conducted, analyzing 85 peer-reviewed studies published in the last decade, of which 65 were deemed relevant and retained for further analysis. These studies were selected based on their relevance to the pathophysiology, diagnostic methodologies, and treatment outcomes for CE, focusing on their implications for fertility and assisted reproductive technologies (ARTs). The findings suggest that CE is associated with impaired endometrial receptivity, increased inflammatory markers, and reduced implantation and pregnancy rates with ARTs. Histopathological assessment using CD138 immunostaining remains the gold standard for diagnosis, while hysteroscopy and molecular microbiological techniques provide complementary diagnostic value. Antibiotic treatment has been shown to significantly improve implantation rates and pregnancy outcomes, particularly in women with recurrent implantation failure. Emerging therapies, including probiotics and regenerative medicine approaches, are being explored as potential adjuncts to the conventional treatment. Early and accurate diagnosis of CE is essential for optimizing reproductive outcomes. Standardized diagnostic protocols and individualized treatment strategies are crucial for improving implantation success and pregnancy rates in affected women. Future research should focus on refining the diagnostic methods and exploring novel therapeutic options to enhance endometrial health and fertility outcomes.

Background and Objectives: Gestational diabetes mellitus (GDM) is a prevalent condition associated with maternal and fetal complications, including preeclampsia, preterm birth, and neonatal risks. This study investigates the prevalence, risk factors, and socio-demographic and medical determinants of GDM in a Romanian cohort. Materials and Methods: This retrospective study analyzed 200 pregnant women aged 22–43, grouped by demographic and health factors. Data included glucose tolerance tests, hypertension, obesity, and socio-demographic evaluations. Statistical analysis, performed in SPSS with p < 0.05, used logistic regression to assess variable associations. Results: GDM prevalence was 10%, with higher rates in women with obesity (25%, p = 0.03) and hypertension (12%, p = 0.01). Urban living was significantly linked to obesity and hypertension (p = 0.02). Cesarean deliveries occurred in 30% of cases (p = 0.02), and term births accounted for 85% (p = 0.01). Factor analysis identified two key patterns, with urban-related health risks (obesity and hypertension) and socio-demographic vulnerabilities (marital status and rural residence) increasing GDM risk. Conclusions: GDM prevalence underscores the impact of medical and socio-demographic factors, stressing the need for tailored interventions like weight management, glycemic control, and equitable healthcare access to reduce risks and improve outcomes for mothers and infants.

Background: Hashimoto’s thyroiditis (HT), the most prevalent autoimmune thyroid disorder in reproductive-age women, has been linked to diminished ovarian reserve and subfertility. This study aimed to evaluate the relationship between HT and key fertility parameters, including hormonal markers and reproductive outcomes, while also exploring the potential impact of thyroid hormone replacement therapy. Methods: A retrospective observational study was conducted on 86 women undergoing fertility evaluation. Participants were divided into two groups based on anti-thyroid peroxidase antibodies (ATPO): the HT group (n = 49) and the control group (n = 37). Among women with HT, 57% were receiving levothyroxine (Euthyrox^®) at the time of assessment. Variables analyzed included serum levels of anti-Müllerian hormone (AMH), thyroid-stimulating hormone (TSH), insulin resistance index (HOMA-IR), number of oocytes retrieved, blastocysts formed, pregnancies achieved, and live births. Statistical methods included t-tests, Mann–Whitney U tests, Pearson/Spearman correlations, and linear regression models. Results: Women in the HT group had slightly lower AMH levels and oocyte counts compared to controls, though these differences did not reach statistical significance. TSH values were higher in the HT group and showed a significant negative correlation with blastocyst formation (p = 0.03). Although TSH also showed negative trends with oocyte count, pregnancies, and live births, these correlations did not reach statistical significance. A post-hoc subgroup analysis revealed that HT patients receiving levothyroxine tended to have higher numbers of oocytes retrieved and blastocysts formed compared to untreated HT patients, suggesting a possible beneficial effect of thyroid hormone replacement, although the differences were not statistically significant. Conclusions: HT is associated with subtle but clinically relevant impairments in ovarian reserve and reproductive potential. Thyroid hormone replacement may offer modest benefits and should be considered in the individualized management of fertility in women with thyroid autoimmunity.

Background/Objectives: Gestational diabetes mellitus (GDM) is a common metabolic disorder during pregnancy, associated with increased risks for both maternal and fetal complications. Insulin resistance plays a central role in its pathophysiology. This study aimed to evaluate the predictive value of the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) in diagnosing GDM and to explore its correlation with clinical and anthropometric parameters in a Romanian population. Methods: A retrospective case–control study was conducted on 320 pregnant women between 24 and 28 weeks of gestation. Based on ADA criteria, participants were divided into 160 with GDM and 160 controls, matched by age and gestational week. Fasting glucose, insulin, BMI, and blood pressure were assessed. HOMA-IR and HOMA-β were calculated. Statistical analyses included t-tests, Pearson correlation, and logistic regression. Results: HOMA-IR was significantly higher in the GDM group (2.9 vs. 1.8; p < 0.001). It correlated with fasting insulin (r = 0.85, p < 0.001), fasting glucose (r = 0.65, p < 0.001), BMI (r = 0.60, p < 0.001), and systolic blood pressure (r = 0.42, p < 0.001). Logistic regression identified HOMA-IR as an independent predictor of GDM (OR = 2.4, 95% CI: 1.6–3.5, p < 0.001), along with BMI (p = 0.01) and maternal age (p = 0.05). Conclusions: HOMA-IR is significantly associated with GDM and may enhance mid-gestational risk assessment when combined with clinical and anthropometric measures. Further studies are needed to validate its predictive accuracy in broader populations.

Background: Sperm morphology is a key factor influencing fertilization and embryo development in assisted reproductive technology (ART). However, the predictive value of sperm deformity indices and selection techniques remains debated. This study evaluated the impact of teratozoospermia on fertilization, blastocyst formation, and embryo quality, comparing conventional and microfluidic sperm selection methods. Methods: A retrospective analysis was conducted on ART cycles involving patients with teratozoospermia. Sperm selection was performed using density gradient centrifugation (DGC) or microfluidic sperm sorting (MFSS). The correlations between the Sperm Deformity Index (SDI), Multiple Anomalies Index (MAI), and Teratozoopermia Index (TZI) with fertilization rates, blastocyst formation, and embryo quality were assessed. Statistical analysis included correlation tests, receiver operating characteristic (ROC) curves, and independent samples t-tests. Results: Patients with severe teratozoospermia exhibited lower fertilization rates (p < 0.01) and reduced blastocyst formation (p = 0.02). The SDI and MAI showed moderate negative correlations with fertilization (r = −0.15 and r = −0.25, respectively) and blastocyst development (r = −0.20 and r = −0.30, respectively), while the TZI had only weak associations (r = −0.10 and r = −0.15, respectively). ROC analysis demonstrated that the SDI and MAI were moderate predictors of embryo viability (AUC = 0.70 and 0.75, respectively). Patients who underwent microfluidic sperm selection had higher fertilization rates (p = 0.03) and improved blastocyst quality (p = 0.04) than those processed with DGC. Conclusions: Severe teratozoospermia negatively affects fertilization and blastocyst formation, with the SDI and MAI showing moderate predictive value for embryo development. The use of microfluidic sperm selection significantly improved embryo quality, supporting its clinical relevance in ART.
