RESUMO

Background and Objectives: This paper aims to assess the role of laser therapy in periodontitis through an innovative approach involving computational prediction and advanced modeling performed through network analysis (Gaussian graphical models-GGMs) and structural equations (SEM). Materials and Methods: Forty patients, exhibiting periodontal pockets with a minimum depth of 5 mm, were randomly divided into two groups: a control group and a laser group. Four specific indicators were measured for each tooth, namely periodontal pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI), and the mean of six measured values was recorded at five time markers (baseline, 6 months, 1 year, 2 years, and 4 years). The assessment algorithm included enrollment, measurements, and differential non-surgical periodontal treatment, according to the group allocation. Scaling, root planing, and chlorhexidine 1% were conducted for the control group, and scaling, root planing and erbium, chromium:yttrium-scandium-gallium-garnet (Er,CR:YSGG) laser therapy were conducted for the laser group. Results: The main results highlight that the addition of laser treatment to scaling and root planing led to notable clinical improvements, decreasing the PPD values, reducing the BOP scores, and increasing the CAL. Conclusions: Notable relationships between the specific indicators considered were highlighted by both the GGMs and by SEM, thus confirming their suitability as proxies for the success of periodontal treatment.

RESUMO

BACKGROUND: The objective of this study was to determine the effects of royal jelly and fermented soy extracts on menopausal symptoms and on quality of life in pre- and post-menopausal women. MATERIALS AND METHOD: This prospective observational study was carried out in a Clinical Hospital of Brasov, Romania, during June 2020 and December 2021. Eighty pre- and post-menopausal women, aged between 45 and 60 years, were included in two groups. The first group (40 women) received a dietary supplement with fermented soy extract twice a day for eight weeks and the second group (40 women) received the same dietary supplement with fermented soy extracts and 1500 mg of royal jelly capsules for eight weeks. After the treatment, the MENQOL score, DASS-21 score, and the mean number and intensity of daily hot flushes were recorded and compared with baseline values. RESULTS: After eight weeks of treatment, the score of the MENQOL questionnaire and all its domains' scores decreased in comparison with the baseline in both groups (p < 0.001). Also, the DASS-21 score (p < 0.001), depression score (p < 0.001), anxiety score (p < 0.001), and stress score (p < 0.001) improved. The mean number and the intensity of hot flushes decreased in both groups (p < 0.001). Comparing these variables after the treatment in both groups, we observed that the women who received dietary supplements with fermented soy extracts and royal jelly capsules recorded better scores for MENQOL (vasomotor, physical, and psychosocial domains) and a more reduced mean number of daily hot flushes. CONCLUSIONS: This observational study suggests that both dietary fermented soy supplements and royal jelly capsules possess beneficial effects against menopausal symptoms, increase the quality of life in pre- and post-menopausal women, and that the effects might be significantly improved if those dietary supplements are administered in association.

RESUMO

Cancer is known as one of the most significant causes of death worldwide, and, in spite of novel therapeutic methods, continues to cause a considerable number of deaths. Targeted molecular diagnosis and therapy using aptamers with high affinity have become popular techniques for pathological angiogenesis and cancer therapy scientists. In this paper, several aptamer-based diagnostic and therapeutic techniques such as aptamer-nanomaterial conjugation, aptamer-drug conjugation (physically or covalently), and biosensors, which have been successfully designed for biomarkers, were critically reviewed. The results demonstrated that aptamers can potentially be incorporated with targeted delivery systems and biosensors for the detection of biomarkers expressed by cancer cells. Aptamer-based therapeutic and diagnostic methods, representing the main field of medical sciences, possess high potential for use in cancer therapy, pathological angiogenesis, and improvement of community health. The clinical use of aptamers is limited due to target impurities, inaccuracy in the systematic evolution of ligands via exponential enrichment (SELEX)stage process, and in vitro synthesis, making them unreliable and leading to lower selectivity for in vivo targets. Moreover, size, behavior, probable toxicity, low distribution, and the unpredictable behavior of nanomaterials in in vivo media make their usage in clinical assays critical. This review is helpful for the implementation of aptamer-based therapies which are effective and applicable for clinical use and the design of future studies.

RESUMO

Fibrinogen as a major inflammation marker and blood coagulation factor has a direct impact on the health of humanity. The variations in fibrinogen content lead to risky conditions such as bleeding and cardiovascular diseases. So, accurate methods for monitoring of this glycoprotein are of high importance. The conventional methods, such as the Clauss method, are time consuming and require highly specialized expert analysts. The development of fast, simple, easy to use, and inexpensive methods is highly desired. In this way, biosensors have gained outstanding attention since they offer means for performing analyses at the points-of-care using self-testing devices, which can be applied outside of clinical laboratories or hospital. This review indicates that different electrochemical and optical sensors have been successfully implemented for the detection of fibrinogen under normal levels of fibrinogen in plasma. The biosensors for the detection of fibrinogen have been designed based on the quartz crystal microbalance, field-effect transistor, electrochemical impedance spectroscopy, amperometry, surface plasmon resonance, localized surface plasmon resonance, and colorimetric techniques. Also, this review demonstrates the utility of the application of nanoparticles in different detection techniques.

RESUMO

Metformin, a widely prescribed medication for type 2 diabetes, has garnered increasing attention for its potential neuroprotective properties due to the growing demand for treatments for Alzheimer's, Parkinson's, and motor neuron diseases. This review synthesizes experimental and clinical studies on metformin's mechanisms of action and potential therapeutic benefits for neurodegenerative disorders. A comprehensive search of electronic databases, including PubMed, MEDLINE, Embase, and Cochrane library, focused on key phrases such as "metformin", "neuroprotection", and "neurodegenerative diseases", with data up to September 2023. Recent research on metformin's glucoregulatory mechanisms reveals new molecular targets, including the activation of the LKB1-AMPK signaling pathway, which is crucial for chronic administration of metformin. The pleiotropic impact may involve other stress kinases that are acutely activated. The precise role of respiratory chain complexes (I and IV), of the mitochondrial targets, or of the lysosomes in metformin effects remains to be established by further research. Research on extrahepatic targets like the gut and microbiota, as well as its antioxidant and immunomodulatory properties, is crucial for understanding neurodegenerative disorders. Experimental data on animal models shows promising results, but clinical studies are inconclusive. Understanding the molecular targets and mechanisms of its effects could help design clinical trials to explore and, hopefully, prove its therapeutic effects in neurodegenerative conditions.

RESUMO

Throughout history, nature has been acknowledged for being a primordial source of various bioactive molecules in which human macular carotenoids are gaining significant attention. Among 750 natural carotenoids, lutein, zeaxanthin and their oxidative metabolites are selectively accumulated in the macular region of living beings. Due to their vast applications in food, feed, pharmaceutical and nutraceuticals industries, the global market of lutein and zeaxanthin is continuously expanding but chemical synthesis, extraction and purification of these compounds from their natural repertoire e.g., plants, is somewhat costly and technically challenging. In this regard microbial as well as microalgal carotenoids are considered as an attractive alternative to aforementioned challenges. Through the techniques of genetic engineering and gene-editing tools like CRISPR/Cas9, the overproduction of lutein and zeaxanthin in microorganisms can be achieved but the commercial scale applications of such procedures needs to be done. Moreover, these carotenoids are highly unstable and susceptible to thermal and oxidative degradation. Therefore, esterification of these xanthophylls and microencapsulation with appropriate wall materials can increase their shelf-life and enhance their application in food industry. With their potent antioxidant activities, these carotenoids are emerging as molecules of vital importance in chronic degenerative, malignancies and antiviral diseases. Therefore, more research needs to be done to further expand the applications of lutein and zeaxanthin.

RESUMO

BACKGROUND: Endometriosis is a chronic and debilitating disease, which affects millions of young women worldwide. Although medicine has incontestably evolved in the last years, there is no common ground regarding the early and accurate diagnosis of this condition, its pathogenic mechanisms, and curative treatment. Even though the spontaneous resolution of endometriosis is sometimes possible, recent reports suggested that it can be a progressive condition. It can associate chronic pelvic pain, vaginal bleeding, infertility, or malignant degenerescence. Conventional treatments could produce many side effects, and despite treatment, the symptoms may reappear. In recent years, experimental evidence suggested that plant-based medicine could exert beneficial effects on endometriosis and endometriosis-related symptoms. This study aims to highlight the pharmaceutical activity of phytochemicals and medicinal plants against endometriosis and to provide a source of information regarding the alternative treatment of this condition. METHODS: For this review, we performed a research using PubMed, GoogleScholar, and CrossRef databases. We selected the articles published between January 2000 and July 2020, written in English. RESULTS: We found 17 medicinal plants and 13 phytochemicals, which have demonstrated their beneficial effects against endometriosis. Several of their biological activities consist of antiangiogenic, anti-inflammatory effects, and oxidative-stress reduction. CONCLUSION: Medicinal herbs and their bioactive compounds exhibit antiangiogenic, antioxidant, sedative and pain-alleviating properties and the effects recorded until now encourage their use for the conservative management of endometriosis.

RESUMO

Background: Pomgranate (Punica granatum) represents a high source of polyphenols with great bioavailability. The role of this fruit in the prevention and treatment of various malignant pathologies has been long time cited in both scientific and non-scientific literature, making thus important to identify its involvement in the pathophysiological processes. The treatment for breast cancer had focused on the inhibition of the mechanisms that governs the estrogen activity. These mechanisms are covered either by the antagonism of the estrogen receptor (ER) or by the inhibition of the estrogen synthesis. Our interest in identifying a bioactive compound rich in polyphenols, which induces both the antagonism of the estrogen receptor, and the inhibition of the estrogen synthesis, revealed us the pomegranate fruit and its derivatives: peel and seeds. Pomegranates' chemical composition include many biological active substances such as flavonols, flavanols, anthocyanins, proanthocyanidins, ellagitannins and gallotannins. Materials and Methods: We performed a review of the scientific literature by using the following keywords: "pomegranate", "breast cancer", "Punica granatum", "pomegranate polyphenols". Our search was performed in the PubMed and Google Scholar databases, and it included only original research written in English from the last 20 years. None of the articles were excluded due to affiliation. A total number of 28 original papers, which mentioned the beneficial activity of pomegranate against breast cancer, were selected. Both clinical and preclinical studies were considered for this review. Results: Recent discoveries pointed out that polyphenols from Punica granatum possess strong anti-cancer activity, exhibited by a variety of mechanisms, such as anti-estrogenic, anti-proliferative, anti-angiogenetic, anti-inflammatory, and anti-metastatic. Pomegranate extracts induced cell cycle arrest in the G0/G1 phase, and induced cytotoxicity in a dose- and time-dependent manner. Moreover, several polyphenols extracted from pomegranate inhibited the invasion potential, migration and viability of breast cancer cells. The effects of pomegranate juice on serum estrogens and other sexual hormones levels were also investigated on two human cohorts. Conclusions: Punica granatum represents a promising area in oncology. The large availability and low cost, associated with the lack of side effects, made from this natural product a great strategy for the management of breast cancer. There are several mechanistic studies in mouse models and in breast cancer cell lines, suggesting the possible pathways through which polyphenols from pomegranate extracts act, but larger and better-controlled studies are necessary in the future. Only two small clinical trials were conducted on humans until now, but their results are contradictory and should be considered preliminary.

RESUMO

Dengue fever is among the most common vector-borne diseases. Dengue virus (DENV), responsible for dengue fever as well as dengue hemorrhagic fever, belongs to the genus flavivirus and family Flaviviridae. Flaviviruses infect various vertebrate species and arthropods and are also responsible for diseases in birds, wild animals, and primates. DENV consists of a single-stranded, positive-sense RNA genome ~11 kb in size. Complete genome and partial gene sequences of geographically distinct DENV-3 strains were retrieved from the GenBank database. The evolutionary divergence of the 33 whole-genome and individual gene sequences of the nucleotides and amino acids of DENV-3 strains were generated with the maximum likelihood (ML) and Bayesian phylogenetic study (BEAST) methods using the MEGA 7 software. The genome size varied from 10,484 to 10,724 nucleotides among the strains with distinct geographical backgrounds belonging to Central America, South-Central Asia, and Eastern Asia. A phylogenetic analysis of the nucleotide and amino acid sequences of these DENV-3 isolates revealed extensive differences in the topologies due to PrM/M, NS1, NS2B, and NS3 genes. These results suggest substantial variation in the evolutionary pathways of the studied genes and genomes.

RESUMO

BACKGROUND: The postpartum period is a difficult time for mother and family. Unfortunately, in some cases, two psychiatric complications may occur: postpartum psychoses (PPP) with a prevalence of 0.2% and a very low incidence of 0.25-0.50 per 1000 deliveries, and post-natal depressions with an incidence of 10 to 20% per 1000 deliveries. The onset of postpartum psychosis is in the first 4 weeks after childbirth with symptoms such as emotional lability, cognitive disorganization, delusional beliefs and hallucinations. It requires hospitalization due to the high risk of suicide and infanticide. The studies reveal that the treatment can include FGAs (first-generation antipsychotics), such as haloperidol, and SGAs (second-generation antipsychotics), such as olanzapine, quetiapine and risperidone. The literature is scarce in what resistant PPP is concerned and no such cases treated with clozapine have been reported, according to our knowledge. The present case report focuses on a female diagnosed with PPP who was treated with clozapine due to the lack of response to adequate dosage of 2 second-generation antipsychotics. CASE PRESENTATION: We present the case of a 30-year-old primiparous woman on her 3rd day after delivery, admitted in the psychiatric emergency unit for agitation, intrusive thoughts with a content frequently related to the infant, ideas of reference, disorganized speech, bizarre behavior, verbal stereotypes, insomnia and anxiety. Due to lack of response to adequate dosage of 2 second-generation antipsychotics, clozapine was initiated up to 250 mg/day. The symptoms remitted in the next 5 days and the patient was discharged. After discharge, at the patient's request, clozapine was replaced by olanzapine. Visit at 1 year revealed full remission of symptoms. CONCLUSION: Although data is extremely limited, clozapine has been shown to be effective and safe in a severe case of treatment-resistant PPP.

RESUMO

Approximately every two hours, a Romanian woman is diagnosed with cervical cancer as the country ranks first in the EU in terms of its mortality rate. This paper aims to identify the main reasons that have led to this situation. First, a study based on secondary data was conducted in order to identify measures taken by the Romanian Ministry of Health for the prevention of this type of cancer. Second, a quantitative study was conducted to evaluate the impact that exposure to information and awareness campaigns has on women's behavior regarding cervical cancer prevention through screening. The results of the research show an increased percentage of the women understanding the importance of screening and the benefits of early diagnosis, but also shows that a high percentage of women postpone the routine checks due to lack of time and financial resources. The research results also indicate that the only free screening program implemented in Romania during 2012-2017 was a failure due to poor procedures, low number of women tested, underfunding and the lack of promotion. Our conclusion is that the Romanian Ministry of Health has to take immediate action by conducting major awareness campaigns and also by implementing functional screening programs.

RESUMO

Cervical cancer represents one of the leading causes of cancer-related death in women all over the world. The infection with human papilloma virus (HPV) is one of the major risk factors for the development of premalignant lesions, which will progress to cervical cancer. Seaweeds are marine organisms with increased contents of bioactive compounds, which are described as potential anti-HPV and anti-cervical cancer agents. Our study aims to bring together all the results of the previous studies, conducted in order to highlight the potency of bioactive molecules from seaweeds, as anti-HPV and anti-cervical agents. This paper is a review of the English literature published between January 2010 and August 2020. We performed a systematic study in the Google Academic and PubMed databases using the key words "HPV infection", "anticancer", "seaweeds", "cervical cancer" and "carcinogenesis process", aiming to evaluate the effects of different bioactive molecules from marine algae on cervical cancer cell lines and on HPV-infected cells. Only original studies were considered for our research. None of the papers was excluded due to language usage or affiliation. Recent discoveries pointed out that sulfated polysaccharides, such as dextran sulfate heparan or cellulose sulfate, blocked the ability of HPV to infect cells, and inhibited the carcinogenesis process. Carrageenans inhibited the virions of HPV from binding the cellular wall. Fucoidan induced the growth inhibition of HeLa cervical cells in vitro. Heterofucans exhibited antiproliferative effects on cancer cell lines. Terpenoids from brown algae are also promising agents with anti-cervical cancer activity. Considering all the results of the previous studies, we observed that great amounts of bioactive molecules from seaweeds could treat both unapparent HPV infection and clinical visible disease. Furthermore, these molecules were very efficient in the treatment of invasive cervical carcinomas. In these conditions, we consider seaweeds extracts as a novel and challenging therapeutic strategy, and we hope that our study paves the way for further clinical trials in the field.

RESUMO

AIMS: This study compared the effectiveness and safety of cervical cerclage combined with cervical pessary in the treatment of cervical incompetence and that of cervical cerclage alone and cervical pessary alone. METHODS: We performed a prospective cohort study of women with cervical incontinence. Subjects were randomized into three groups: cerclage, pessary, and cerclage and pessary combined. RESULTS: A total of 75 patients with cervical incompetence were enrolled: 37.3% patients had a cervical length <15 mm, and 62.5% had a cervical length of 15-25 mm. Patients with increased body mass index were significantly likely to have a short cervix (p = .06); patients with a short cervix had earlier rupture of the membrane. The cerclage and pessary groups had more spontaneous abortions than the combined treatment group, which had no abortions or premature births. The mean gestational ages at delivery for the cerclage group (37.82 weeks) and the pessary group (35.73 weeks) were smaller than for the combined treatment group (38.33 weeks). The premature rupture of membranes that was correlated with cervical length had a higher incidence in the pessary group (26.9%). CONCLUSION: Placement of a cervical cerclage combined with a cervical pessary is a safe technique and has a high success rate in the treatment of cervical incompetence.

RESUMO

Spirulina is a phytosynthetic filamentous cyanobacterium with microscopic dimensions, which naturally grows in the highly-salted alkaline lakes of Africa, Mexico, America, and Asia. Several bioactive peptides extracted from Spirulina were demonstrated to possess antimicrobial, antiviral, antitumor, immunomodulatory, antiallergic and antihypertensive properties. It has been reported that the consumption of Spirulina could prevent or manage metabolic syndrome components. In women, metabolic disorders are more prevalent during menopause. Postmenopausal women present higher waist circumference, increased blood pressure, hypertriglyceridemia, hyperglycemia, and decreased HDL-cholesterol values, leading to an increased risk of cardiovascular events. Therefore, in order to prevent cardiovascular diseases, it is essential to manage the components of the metabolic syndrome during the postmenopausal period. As recent reports indicated the efficiency of Spirulina supplementation in the management of the metabolic syndrome components, our study aims to review all the clinical trials conducted on this topic. Our main objective is to have a better understanding of whether and how this cyanobacterium could manage the abnormalities included in the metabolic syndrome and if it could be used as a therapeutic approach in postmenopausal women with this condition. We selected relevant articles from PubMed, Google Scholar and CrossRef databases, and a total number of 20 studies met our criteria. All included clinical trials indicated that Spirulina has positive effects in managing metabolic syndrome components. Spirulina is a valuable cyanobacterium that can be used as a food supplement for the management of metabolic syndrome, and it is able to reduce the risk of cardiovascular events. The optimal dose and period of administration remain a debated subject, and future investigations are required. Considering the beneficial effects reported against each component of the metabolic syndrome, Spirulina could also be effective in the postmenopausal period, when this syndrome is the most prevalent, but there is a strong need for human clinical trials in order to sustain this observation.

RESUMO

Women's life stages are based on their reproductive cycle. This cycle begins with menstruation and ends with menopause. Aging is a natural phenomenon that affects all humans, and it is associated with a decrease in the overall function of the organism. In women, aging is related with and starts with menopause. Also, during menopause and postmenopausal period, the risk of various age-related diseases and complaints is higher. For this reason, researchers were pushed to find effective remedies that could promote healthy aging and extended lifespan. Apitherapy is a type of alternative medicine that uses natural products from honeybees, such as honey, propolis, royal jelly, etc. Royal jelly is a natural yellowish-white substance, secreted by both hypopharyngeal and mandibular glands of nurse bees, usually used to feed the queen bees and young worker larvae. Over the centuries, this natural product was considered a gold mine for traditional and natural medicine, due to its miraculous effects. Royal jelly has been used for a long time in commercial medical products. It has been demonstrated to possess a wide range of functional properties, such as: antibacterial, anti-inflammatory, vasodilatative, hypotensive, anticancer, estrogen-like, antihypercholesterolemic, and antioxidant activities. This product is usually used to supplement various diseases such as cardiovascular disease, Alzheimer's disease, sexual dysfunctions, diabetes or cancer. The main objective of this study is to highlight the effectiveness of royal jelly supplementation in relieving menopause symptoms and aging-related diseases. We also aimed to review the most recent research advances regarding the composition of royal jelly for a better understanding of the effects on human health promotion.

RESUMO

BACKGROUND: Psychotic episodes in the postpartum period are life-threatening psychiatric emergencies, requiring urgent medical attention and admission to a psychiatric hospital. AREAS OF UNCERTAINTY: Although the postpartum psychosis (PPP) is the most severe psychiatric disorder associated with parturition, there is little information about what interventions are most effective. Because there are no specific guidelines for the treatment of PPP, the aim of the present review was to examine the available evidence regarding the treatment of PPP. DATA SOURCES: The PubMed database was searched based on the title and the abstract, using the key words "postpartum psychosis," "postpartum psychosis antipsychotics," "postpartum psychosis treatment," and "postpartum psychosis pharmacotherapy," for both interventional and observational, irrespective of language. RESULTS: A number of 14 publications met the study criteria, including case reports and case series. The antipsychotics (APs) use included both first generation APs, such as haloperidol and chlorpromazine, and second generation APs, mainly, olanzapine, quetiapine, and risperidone. The most frequently used AP was olanzapine. Olanzapine and quetiapine seem to be the most acceptable during breastfeeding. Proposed treatment algorithms for the successful management of PPP are discussed. CONCLUSIONS: The existing studies to date do not allow to draw a definitive conclusion regarding which treatment is the most effective or the most adequate. Existing evidence suggests that APs alone or in combination are responsible for sustained remission and that treated PPP has a higher pace of improvement of the mental status, with a rapid discharge from the hospital. Clinical studies to compare the efficacy and safety of different APs in the PPP are needed to provide guidance on treatment interventions.

RESUMO

Viola tricolor Linn. is used as cardio-protective and anti-hypertensive agent in traditional medicine. Current study objective was to evaluate cardio-protective and hypotensive effects of Viola tricolor L. in vitro and in vivo studies. Viola tricolor L. crude extract (Vt.Cr) and its fractions (Aqueous and organic) were tested at rabbit atria and aorta coupled to Power Lab Data Acquisition System for cardio depressant and vasorelaxant effects in vitro whereas in vivo Blood Pressure was checked by invasive method in normotensive ketamine-diazepam anesthetized rats. Isoproterenol was employed for acute myocardial infarction (AMI) and left ventricular hypertrophy (LVH) development and cardioprotective effects of Vt.Cr were evaluated hemodynamically and histopathologically. Vt.Cr and its fractions decreased heart rate and contractile force in paired atria and relaxed Phenylephrine (1 µM) and K+ (80 mM) stimulated contractions in aorta possibly mediated through Voltage dependent L-type calcium channels blockage supported by in vivo hypotensive action. In LVH, Vt.Cr lowered Angiotensin Converting Enzymes and renin, increased cyclic Guanosine Monophosphate and nitric oxide levels, decreased cardiomyocytes size and fibrosis attributed to Gallic acid as detected by High Performance Liquid Chromatography. Partial positive results were seen hemodynamically and histologically in AMI Viola tricolor L. showed vasorelaxant, cardio-relaxant, hypotensive, and cardio protective effect validating traditional practice in cardiovascular disorders.

RESUMO

BACKGROUND: Early and accurate diagnosis of endometriosis is crucial for the management of this benign, yet debilitating pathology. Despite the advances of modern medicine, there is no common ground regarding the pathophysiology of this disease as it continues to affect the quality of life of millions of women of reproductive age. The lack of specific symptoms often determines a belated diagnosis. The gold standard remains invasive, surgery followed by a histopathological exam. A biomarker or a panel of biomarkers is easy to measure, usually noninvasive, and could benefit the clinician in both diagnosing and monitoring the treatment response. Several studies have advanced the idea of biomarkers for endometriosis, thereby circumventing unnecessary invasive techniques. Our paper aims at harmonizing the results of these studies in the search of promising perspectives on early diagnosis. METHODS: We selected the papers from Google Academic, PubMed, and CrossRef and reviewed recent articles from the literature, aiming to evaluate the effectiveness of various putative serum and urinary biomarkers for endometriosis. RESULTS: The majority of studies focused on a panel of biomarkers, rather than a single biomarker and were unable to identify a single biomolecule or a panel of biomarkers with sufficient specificity and sensitivity in endometriosis. CONCLUSION: Noninvasive biomarkers, proteomics, genomics, and miRNA microarray may aid the diagnosis, but further research on larger datasets along with a better understanding of the pathophysiologic mechanisms are needed.

RESUMO

RATIONALE, AIMS, AND OBJECTIVES: It is estimated that 25% of pregnancies worldwide end in induced abortion. In Romania, the abortion situation shows a specific pattern. Following the fall of the communist regime, first-trimester abortions were legalized, and between 1990 and 1992, the country's abortion rate was the highest in the world, with 182 abortions per 1000 women of reproductive age. However, there are currently no statistically reliable data, as some abortions are not reported. The purpose of this study was to identify the main circumstances that determine the choice to undergo abortion with all related potential risks, rather than using contraception. METHOD: We conducted a prospective type 1 cohort study based on a Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement that included women who presented at Bucur Maternity, Saint John Hospital, Bucharest, for abortion during the first trimester, between July and December 2018. The patients were asked to complete a 21-item questionnaire based on psychosocial data. RESULTS: The study included 119 patients, with a mean age of 29.57 years. Their educational level was average (ie, 51.3%, 4.2%, and 8.4% had completed high school, elementary school, and college or university, respectively). Most women were married (46.2%), and 47.9% were unemployed. The main reason for deciding to undergo an abortion was poverty (P = .014), and guilt was correlated with this decision (P = .004). CONCLUSION: The profiles of the women who chose to undergo an abortion as a family planning method were as follows: in the third decade of life, resident of urban areas, married, unemployed, and with a low family income. The main reasons for abortion were financial status, advanced maternal age, incompatibility of pregnancy with future plans, and the desire to postpone conception.

RESUMO

BACKGROUND: In 1989, Botulinum toxin (BoNT) was accepted by the FDA for the management of some ophthalmic disorders. Although it was initially considered a lethal toxin, in recent times, Botulinum toxin A (BoNT-A), which is the more used serotype, has expanded to cover different clinical conditions, primarily characterized by neuropathic pain, including migraines and headaches. Evidence suggests that migraines are influenced by hormonal factors, particularly by estrogen levels, but very few studies have investigated the prevalence and management strategies for migraines according to the hormonal status. The effects of several therapeutic regimens on migraines have been investigated, but the medications used varied widely in proven efficacies and mechanisms of action. BoNT-A is increasingly used in the management of migraine and several placebo-controlled trials of episodic and chronic migraine are currently underway. This paper is a review of the recently published data concerning the administration of BoNT-A in the prevention of chronic migraines. Considering the lack of population-based studies about the effectiveness of BoNT-A in the alleviation of premenstrual and perimenopausal migraines, this study proposes a new perspective of the therapeutic approach of migraine syndrome associated with menopausal transition and the premenstrual period. METHODS: We selected the reviewed papers from CrossRef, PubMed, Medline, and GoogleScholar, and a total of 21 studies met our inclusion criteria. RESULTS: To date, no specific preventive measures have been recommended for menopausal women with migraines. BoNT-A often reduces the frequency and intensity of migraine attacks per month; the treatment is well tolerated and does not exhibit a significantly higher rate of treatment-related side effects. No population-based studies were conducted in order to highlight the role of BoNT-A in menopause-related migraines, neither in menstrual migraines. CONCLUSION: There is a need for further research in order to quantify the real burden of menstrual and perimenopausal migraines and to clarify if BoNT-A could be used in the treatment of refractory postmenopausal and premenstrual migraines.
