RESUMO

In brief: Alpha-ketoglutarate is a common metabolite in the tricarboxylic acid cycle and is central in modulating the reproductive potential in animal models. The present scoping review systematically covers the spectrum of a wide range of evidence from different viewpoints, focusing on the underlying processes and mechanisms of the developmental framework, aiming to fill the gaps within the existing literature. Abstract: Alpha-ketoglutarate is an important intermediate molecule in the tricarboxylic acid cycle with a prominent role in distinct biological processes such as cellular energy metabolism, epigenetic regulation, and signaling pathways. We conducted a registered scoping review (OSF: osf.io/b8nyt) to explore the impact of exogenous supplementation on reproductive capabilities. Our strategy included evaluating the main research literature from different databases like PubMed-MEDLINE, Web of ScienceTM, Scopus, and Excerpta Medica dataBASE using a specific systematic layout to encompass all investigations based on experimental models and critically compare the results. Twenty-one studies were included in the main body of this manuscript, which revealed that exogenous supplementation induced dose- and sex-dependent modifications. This metabolite modulates the expression of pluripotency genes, thus controlling stem cells' self-renewal, differentiation, and reprogramming dynamics, while also alleviating structural transformations induced by exposure to heavy metals and other inhibitors. This significantly demonstrated a direct influence of alpha-ketoglutarate in mitigating oxidative stress and prolonging the lifespan, consequently supporting metabolic and endocrine adjustments. It influences oocyte quality and quantity, delays reproductive aging, and establishes an optimal competence framework for development with minimal risk of failure. Therefore, alpha-ketoglutarate is linked to improving reproductive performance, but further studies are needed due to a lack of studies on humans.

RESUMO

PURPOSE: To investigate whether the ovarian stimulation with follitropin delta in an individualized algorithm-based manner is inferior to recombinant human-follicle stimulating's follitropin alfa or follitropin beta conventional dosing regarding a series of established primary endpoints. METHODS: We conducted a registered systematic review (CRD42024512792) on PubMed-MEDLINE, Web of Science™, Cochrane Database of Systematic Reviews, and Scopus. Our search was designed to cover all relevant literature, particularly randomized controlled trials. We critically and comparatively analyzed the outcomes for each primary endpoint based on the intervention, reflected by the positive ßhCG test, clinical pregnancy, vital pregnancy, ongoing pregnancy, live birth, live birth at 4 weeks, and multiple pregnancies. RESULTS: Six randomized controlled trials were included in the quality assessment as priority manuscripts, revealing an 83.3% low risk of bias. Follitropin delta led to non-significant differences in each parameter of interest from positive ßhCG test (691; 53.44% vs. 602; 46.55%), ongoing pregnancies (603; 53.79% vs. 518; 46.20%), clinical and vital pregnancies (1,073; 52.80% vs. 959; 47.19%), to live birth and at 4 weeks (595; 54.14% vs. 504; 45.85%) with only 2 losses, and even multiple pregnancies (8; 66.66% vs. 4; 33.33%). However, follitropin delta was well-tolerated among hypo- and hyper-responders without significant risk of ovarian hyperstimulation syndrome and/or preventive interventions in contrast with follitropin alfa or follitropin beta. CONCLUSION: The personalized individualized-based algorithm dosing with follitropin delta is non-inferior to conventional follitropin alfa or follitropin beta. It is as effective in promoting a similar response in women without significant comparable adverse effects.

RESUMO

Background: Infertility is a global burden that affects both sexes with the male component remaining as an explored yet crucial research field that might offer novel evidence. Material and Methods: The present narrative mini-review aims to summarize all existing literature regarding the composition of the seminal microflora in infertile men. We performed searches in PubMed/Medline, ISI Web of Knowledge, Scopus, and ScienceDirect between 2018 and 2022 using a combination of keywords. Results: A total of n = 33 studies met the eligibility criteria and were further considered. From this, n = 14 were conducted on human patients, n = 3 on zebrafish (Danio rerio), n = 5 on rats, and n = 11 on mice. In twenty-five out of thirty-three papers, the authors sequenced the 16S rRNA; situations occurred where researchers focused on standard laboratory protocols. Lactobacillus and Bifidobacterium are widely recognized as putative beneficial lactic bacteria. These two entities are capable of restoring the host's eubiosis to some extent, blocking pathogens' proliferation and endotoxins, and even alleviating specific patterns encountered in disease(s) (e.g., obesity, type 1 diabetes) due to prolonged exposure to toxicants in adults or from a developmental stage. Over the years, distinct approaches have been perfected, such as the transfer of feces between two species or conventional rudimentary products with proven efficiency. Conclusions: The seminal microflora is decisive and able to modulate psychological and physiological responses. Each individual possesses a personalized microbial profile further shaped by exogenous factors, regardless of sex and species.

RESUMO

OBJECTIVES: It has been recently documented that Romania has the highest prevalence of adolescent pregnancy in Europe. MATERIAL AND METHODS: Therefore, the present study aims to offer a conclusive view of the current situation by assessing a series of parameters in the last 11 years. RESULTS: Throughout the present manuscript, we showed that 1788 pregnancies occurred in the last 11 years in just one center from the northeastern region of Romania. The Kolmogorov-Smirnov test (p < 0.05) performed suggests that gestational age does not follow a normal distribution; an interval during which 899 (50.27%) male and 889 (49.72%) female babies were born. There were a total of 1383 (86.00%) deliveries at full-term and 225 (13.99%) were under 37 weeks. Of 1788 teenage girls, 1467 (82.04%) were from the rural area, whereas 321 (17.95%) from the urban area. CONCLUSIONS: Fortunately, one common feature that we observed was that starting from 2017 there was a significant reduction within the last 2 studied parameters, the situation being much more fluctuating until 2014.

RESUMO

Endometriosis (EMS) is a benign condition characterized by a systemic inflammation that affects fertile women at reproductive age. Ultrasound became, in recent years, the method of choice for both effective diagnostic and preoperative planning. Therefore, accurate characterization and mapping of endometriotic lesions is imperative in such circumstances to enable optimal approach of treatment, whether surgical or non-surgical based on the severity of the findings. This pictorial essay outlines a practical approach to evaluating patients with deep endometriosis by means of transvaginal ultrasound. The technical aspects are in conjunction with both consensus of the International Deep Endometriosis Analysis (IDEA) group and the hands-on experience acquired through daily clinical practice.

RESUMO

Background and objectives: The latest reports suggest that follitropin delta is a highly efficient recombinant human follicle-stimulating hormone (r-hFSH) that became a part of the current assisted reproductive technologies (ARTs). Therefore, the present study aims to assess a series of parameters (follicles, oocytes, and embryos) and further by the outcomes in women following the administration of follitropin delta. Materials and methods: This observational study included 205 women. They were aged between 21 and 43 years (mean 33.45) and an anti-Müllerian hormone (AMH) level ranging from 0.11 to 16.00 ng/dL (mean 2.89). Results: In accordance with the established methodology and following the centralization of data, a total of fifty-eight pregnancies (28.29%) were achieved; forty-five (36.88%) were achieved in women under 35 years and thirteen (15.66%) in women above 35 years. These figures are positively correlated with women's age considering that the number of follicles >18 mm, oocytes fertilized and embryo(s) varies among groups. Regarding the interest parameters, we noted n = 1719 follicles > 18 mm, n = 1279 retrieved oocytes, and n = 677 embryos at day 3. On the other hand, the following figures have been registered in women above 35 years: 814-follicles > 18 mm, 612 oocytes retrieved and 301 embryos at day 3. During this study, we registered only three cases of abortions (n = 1-0.81% in women under 35 years and n = 2-2.40% in women above 35 years). Nine pregnancies (7.37%) were stopped from evolution in females under 35 years, and twelve pregnancies (n = 8-6.55% in women under 35 years, while n = 4 in women above 35 years) were unsuccessful. A twin pregnancy has been confirmed (1.20%) in women above 35 years, six ongoing pregnancies (4.91%) in those under 35 years, and two in both groups (one per group-n = 1-0.81%, and 1.20%-n = 1) in which we did not know the exact result were registered at the end of the established studied interval. However, there were also situations in which the treatment cause an over-reactivity or had no effect; n = 2 were non-responders, and n = 1 exhibited moderate ovarian hyperstimulation syndrome (OHSS). Conclusions: Based on our results, we strongly encourage the use of this recombinant gonadotropin on a much larger scale.

RESUMO

Background and objectives: Abdominal wall endometriosis, also known as scar endometriosis, is a rare condition that is becoming increasingly common. The recent rise in incidence is attributed primarily to the surge of cesarean births, figures that could be influenced in a positive manner considering the improvements brought towards the ultrasound diagnostic methods that have been made in recent years. Materials and Methods: Here we report the cases of two Caucasian women of 38- (G2P2) and 36-years old (G1P1), both subjected to an ultrasound examination due to a specific symptomatic panel reported during anamnesis. Independently of the current status, in the first patient, there were no reported symptom-specific associations with endometriosis, but she had a known history of mild hereditary thrombophilia; the second woman suffered from two conditions positively associated with endometriosis. Results: In both cases, abnormal structures were revealed, with the diagnostic(s) of endometriosis being histologically confirmed based on a set of features observed during the investigation. Conclusions: This paper aims to highlight the importance of reducing cesarean births and to consider the diagnosis of scar endometriosis in women with a history of obstetric or gynaecological surgeries who present with cyclic, recurrent abdominal pain.

RESUMO

Asherman syndrome is a multifaceted condition describing the partial or complete removal of the uterine cavity and/or cervical canal. It is a highly debatable topic because of its pronounced influence on both reproductive outcomes and gynaecologic symptoms. The latest reports demonstrated that trauma to the endometrium is the main cause of intrauterine adhesion formation. Left untreated, such adhesions gradually lead to a range of repercussions ranging from mild to severe. Considering the lack of non-invasive approaches, the advent of hysteroscopy has revolutionized the entire field, being otherwise considered the most efficient tool offering new directions and amplifying the chances of treating the Asherman syndrome.
