Infertility is a global health issue affecting women and men of reproductive age with increasing incidence worldwide, in part due to greater awareness and better diagnosis. Assisted reproduction technologies (ART) are considered the ultimate step in the treatment of infertility. Recently, artificial intelligence (AI) has been progressively used in the many fields of medicine, integrating knowledge and computer science through machine learning algorithms. AI has the potential to improve infertility diagnosis and ART outcomes estimated as pregnancy and/or live birth rate, especially with recurrent ART failure. A broad-ranging review has been conducted, focusing on clinical AI applications up until September 2022, which could be estimated in terms of possible applications, such as ultrasound monitoring of folliculogenesis, endometrial receptivity, embryo selection based on quality and viability, and prediction of post implantation embryo development, in order to eliminate potential contributing risk factors. Oocyte morphology assessment is highly relevant in terms of successful fertilization rate, as well as during oocyte freezing for fertility preservation, and substantially valuable in oocyte donation cycles. AI has great implications in the assessment of male infertility, with computerised semen analysis systems already in use and a broad spectrum of possible AI-based applications in environmental and lifestyle evaluation to predict semen quality. In addition, considerable progress has been made in terms of harnessing AI in cases of idiopathic infertility, to improve the stratification of infertile/fertile couples based on their biological and clinical signatures. With AI as a very powerful tool of the future, our review is meant to summarise current AI applications and investigations in contemporary reproduction medicine, mainly focusing on the nonsurgical aspects of it; in addition, the authors have briefly explored the frames of reference and guiding principles for the definition and implementation of legal, regulatory, and ethical standards for AI in healthcare.

Although there are substantial data linking thyroid autoimmunity (TAI) and infertility, data regarding assisted reproductive technology (ART) outcomes and TAI markers in follicular fluid (FF) of women undergoing ART are scarce. Objective of the study was to assess the association of the levels of thyroid autoantibodies in FF and ART outcome expressed as the achieved pregnancies. This study enrolled 52 women undergoing ART (26 TAI positive subjects and 26 age and body mass index matched TAI negative controls). Blood samples were drawn before the initiation of protocol for controlled ovarian stimulation, and thyrotropin (TSH), free triiodothyronine (fT3), free thyroxine (fT4), thyroid peroxidase antibodies (TPOAbs) and thyroglobulin antibodies (TgAbs) levels were measured. TSH, fT4, TPOAbs, TgAbs and progesterone levels were also measured in FF. There were no significant differences between the groups regarding mean levels of FF TSH and FF fT4. Statistically significant correlation was discovered regarding the levels of serum and FF TPOAbs (0,961, p<0.001 in TAI positive, 0,438, p = 0.025 in TAI negative group) and TgAbs (0,945, p<0.001 in TAI positive, 0,554, p = 0.003 in TAI negative group). Pregnancies rates per initiated cycle and per embryotransfer cycle were significantly different between TAI positive and TAI negative group, (30.8% vs 61.5%), p = 0.026 and (34.8% vs 66.7%), p = 0.029, respectively. Multivariate analysis showed that TAI positive women had less chance to achieve pregnancy (p = 0.004, OR = 0.036, 95% CI 0.004–0.347). Higher levels of thyroid autoantibodies in FF of TAI positive women are strongly correlated with serum levels and may have effect on the post-implantation embryo development.

Graves’ ophthalmopathy (GO) is an autoimmune disease affecting ocular and orbital tissues. Overproduction of tumor necrosis factor  (TNF-) in rheumatoid arthritis (RA) and GO has destructive consequences. The subject of this paper is a case of a female patient initially diagnosed with primary hypothyroidism substitution with levothyroxine, and subsequent diagnosis of RA with insufficient therapeutic efficacy of a standard medication. Three years later, the patient presented symptoms and signs of GO. Etanercept was administrated for RA, and after four months, an improvement of the eye symptoms and reduced exophthalmos were observed and confirmed using visual methods. Graves’ ophthalmopathy association with primary hypothyroidism is uncommon. The treatment of RA using etanercept led to clinical improvement of GO symptoms, which indicates that RA and GO may share similar pathogenic features. The paper suggests that etanercept may suppress the symptoms and clinical signs of GO. However, controlled trials are needed to further evaluate the effect of TNF- inhibitors, particularly etanercept, and to compare its side effects with the current options for medical treatment.

As a leading complication of diabetes mellitus, diabetic neuropathy (DN) represents a major public health challenge due to its high prevalence and impact on patients’ quality of life. The most common form, diabetic peripheral neuropathy (DPN), is characterized by progressive sensory loss, neuropathic pain, and autonomic dysfunction, all of which can significantly increase the risk of serious complications, such as foot ulcers and amputations. Traditionally, therapeutic strategies for DN have been largely limited to symptomatic management. However, recent advancements in diabetes therapy have opened promising avenues for disease-modifying interventions. In particular, incretin-based therapies and sodium-glucose co-transporter 2 (SGLT2) inhibitors have attracted increasing interest not only for their glucose-lowering effects, but also for their broader metabolic, renal, and cardiovascular benefits. In this narrative review, we synthesize emerging evidence on the potential role of these innovative therapies in the management of DN. Preclinical models, clinical trials and real-world observational studies strongly support the hypothesis that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and SGLT2 inhibitors may confer neuroprotective benefits. Beyond these established classes, novel agents such as dual and triple receptor agonists are currently being investigated. Although clinical data on their effects in DN are still limited, the simultaneous activation of multiple metabolic pathways suggests the potential for synergistic neuroprotective effects through enhanced regulation of glucose and lipid metabolism, attenuation of systemic inflammation and oxidative stress, improvement of mitochondrial function and reduction of neuronal damage. Although innovative diabetes therapies are still in early stages of development, they reflect a rapidly evolving landscape in the management of DN in the future. Graphical Abstract

Growing interest in incretin-based therapies for diabetes mellitus has led to an increased evaluation of their potential effects on cancer development. This review aims to synthesize recent evidence regarding the relationship between incretin-based therapies and cancer risk. We conducted a comprehensive literature review focusing on studies investigating dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonists in relation to various malignancies. Current findings suggest that while these therapies demonstrate potential benefits, including weight reduction and metabolic regulation, concerns remain regarding their long-term safety profile. Notably, some studies indicate an increased risk of thyroid and pancreatic cancers, while others report protective effects against prostate, colorectal, and breast cancers. Given the complexity of their effects, further long-term studies and post-marketing surveillance are warranted. This review highlights the need for careful clinical assessment when prescribing incretin-based therapies to patients who may be at increased risk of cancer.

Thyroid function undergoes significant alterations during pregnancy due to changes in hormone levels and higher metabolic demands. The thyroid gland in pregnancy enlarges by 10%; however, in iodine-deficient areas, this growth might reach 40%. Elevated levels of human chorionic gonadotropin (hCG) in early pregnancy leads to increased thyroid hormone production. While triiodothyronine (T3) and thyroid-stimulating hormone (TSH) do not cross the placenta, thyroxine (T4) does. Thyroid hormone demands peaks between weeks 16 and 20 of pregnancy and remains high until delivery. There is a rise in the levels of thyroxine-binding globulin (TBG), during the period of pregnancy, raising total T4 and T3 levels while TSH levels usually decrease. Pregnancy-related thyroid disorders, such as hypothyroidism, hyperthyroidism, and autoimmune thyroid diseases (AITD), carry the potential to impair the well-being of both the child as well as the mother. A range of 5–20% of women belonging to the reproductive age group have AITD, which can be associated with the possibility of infertility, miscarriages, and/or poor pregnancy outcomes. If improperly managed, overt hypothyroidism can cause severe complications such as developmental delay and preeclampsia. Effective management requires regular monitoring and appropriate treatment adjustment. Treatment for hypothyroidism involves levothyroxine, whereas cautious use of antithyroid medications is advised for hyperthyroidism. Postpartum thyroiditis (PPT), an autoimmune condition occurring after childbirth, requires careful management to address both hyperthyroid and hypothyroid phases. A comprehensive understanding and management of these conditions are critical for optimizing maternal and fetal health outcomes. Thyroid disorders are common in women of reproductive age group.
