Asymptomatic 39 Weeks Abdominal Pregnancy - Video Report of a Case Occurred in Ivory Coast Resulting in a Live Birth.

BACKGROUND: Despite the current advances in antenatal care and imaging methodologies in obstetrics, cases of advanced abdominal pregnancies are still reported, mostly in low- and middle-income countries where frequently only a few perinatal checks are performed and where these methodologies are sometimes not adopted in obstetrical outpatient settings. CASE PRESENTATION: We report the video of a case of a 20-year-old I gravida Ivorian patient, sent to CHU de T reichville in Abidjan, Ivory Coast, for management of abdominal 39 weeks pregnancy after routine antenatal care. She was asymptomatic with a live foetus in transverse lie position. The anamnesis revealed four prenatal checks without ultrasound evaluation, the first one at 24 weeks of pregnancy. Emergency median longitudinal sub-umbilical laparotomy incision was performed. Foetal extraction was realized by transplacental incision due to omental placental implantation. A live female baby weighting 3350 grams was delivered, presenting bilateral clubfeet and an enlarged neck. The release of the adherent placenta required a partial omentectomy and left adnexectomy and was carefully removed following active bleeding from its detached margins. The newborn died of respiratory distress on the first day after birth. No autopsy was performed. Postoperative morbidity for the woman was minimal and she was discharged on the seventh post-operative day in good general condition. CONCLUSION: Abdominal pregnancies with a normal live foetus at such an advanced gestational age are extremely rare, and there are no available videos in the extant literature of the surgical procedure performed. Standardization of treatment principles, pre-operative preparation with imaging techniques (MRI, embolization of placental vessels) and adequately equipped and staffed neonatal units are necessary to optimize the foetus-maternal outcomes.

Overview of Curcumin and Piperine Effects on Glucose Metabolism: The Case of an Insulinoma Patient's Loss of Consciousness.

The hypoglycemic properties of curcumin supplements in therapeutic doses are well-known and may represent a useful tool for the treatment of chronic diseases such as metabolic syndrome, insulin resistance and type 2 diabetes. The poor bioavailability of curcumin can be improved with the concomitant administration of piperine, with no severe adverse effects on glycemia reported so far in the literature. In this article, we further discuss a previously reported case of a helicopter pilot, affected by grade I obesity who, under curcumin and piperine treatment, experienced a transient loss of consciousness (TLOC), during a low-altitude flight. This episode led to a diagnosis of insulinoma, previously asymptomatic. We hypothesized that the combined effects of curcumin and piperine might have caused a severe hypoglycemic episode and subsequent TLOC. Therefore, further studies should be conducted to evaluate the safety of curcumin and piperine supplementation in subjects with impaired glucose metabolism and insulin secretion.

Microgravity and the intervertebral disc: The impact of space conditions on the biomechanics of the spine.

The environmental conditions to which astronauts and other military pilots are subjected represent a unique example for understanding and studying the biomechanical events that regulate the functioning of the human body. In particular, microgravity has shown a significant impact on various biological systems, such as the cardiovascular system, immune system, endocrine system, and, last but not least, musculoskeletal system. Among the potential risks of flying, low back pain (LBP) has a high incidence among astronauts and military pilots, and it is often associated with intervertebral disc degeneration events. The mechanisms of degeneration determine the loss of structural and functional integrity and are accompanied by the aberrant production of pro-inflammatory mediators that exacerbate the degenerative environment, contributing to the onset of pain. In the present work, the mechanisms of disc degeneration, the conditions of microgravity, and their association have been discussed in order to identify possible molecular mechanisms underlying disc degeneration and the related clinical manifestations in order to develop a model of prevention to maintain health and performance of air- and space-travelers. The focus on microgravity also allows the development of new proofs of concept with potential therapeutic implications.

Role of Luteolin as Potential New Therapeutic Option for Patients with Glioblastoma through Regulation of Sphingolipid Rheostat.

Glioblastoma (GBM) is the most aggressive brain tumor, still considered incurable. In this study, conducted on primary GBM stem cells (GSCs), specifically selected as the most therapy-resistant, we examined the efficacy of luteolin, a natural flavonoid, as an anti-tumoral compound. Luteolin is known to impact the sphingolipid rheostat, a pathway regulated by the proliferative sphingosine-1-phosphate (S1P) and the proapoptotic ceramide (Cer), and implicated in numerous oncopromoter biological processes. Here, we report that luteolin is able to inhibit the expression of SphK1/2, the two kinases implicated in S1P formation, and to increase the expression of both SGPL1, the lyase responsible for S1P degradation, and CERS1, the ceramide synthase 1, thus shifting the balance toward the production of ceramide. In addition, luteolin proved to decrease the expression of protumoral signaling as MAPK, RAS/MEK/ERK and PI3K/AKT/mTOR and cyclins involved in cell cycle progression. In parallel, luteolin succeeded in upregulation of proapoptotic mediators as caspases and Bcl-2 family and cell cycle controllers as p53 and p27. Furthermore, luteolin determined the shutdown of autophagy contributing to cell survival. Overall, our data support the use of luteolin as add-on therapy, having demonstrated a good ability in impairing GSC viability and survival and increasing cell sensitivity to TMZ.

Emotional and autonomic response to visual erotic stimulation in patients with functional hypothalamic amenorrhea.

Introduction: Functional hypothalamic amenorrhea (FHA) is a clinical condition associated with high levels of physiological and psychological stress ranging from weight loss to maladaptive behavior and coping skills. A reliable measure of the psychophysiological response to stress and the ability to cope with stimuli is heart rate variability (HRV). Through the sympathetic (SNS) and parasympathetic nervous system (PNS), the autonomic nervous system (ANS) promotes various changes in HRV that reflect the individual's psychophysiological response to stress. FHA patients are characterized by high levels of PNS activation during psychological load, suggesting that parasympathetic hyperactivation could be a pathology marker. Methods: In the present study, we examine changes in HRV during observation of erotic, neutral, and disgusting images in 10 patients with FHA [(mean ± S.D.) age: 26.8 ± 5.9] and in 9 controls (age: 25.4 ± 6.4; BMI: 22.47 ± 2.97) to assess the differential activation of PNS and SNS between FHA patients and controls matched for age and without other clinical conditions. Results: Our results showed that FHA patients had significantly higher HRV activation while observing high emotional value images and not during the observation of neutral images confirming a parasympathetic hyperactivation. Discussion: HRV and cognitive and psychological testing, could provide new insights into understanding such a clinically understudied condition and provide further tools for clinical diagnosis and treatment.

Space flight and central nervous system: Friends or enemies? Challenges and opportunities for neuroscience and neuro-oncology.

Space environment provides many challenges to pilots, astronauts, and space scientists, which are constantly subjected to unique conditions, including microgravity, radiations, hypoxic condition, absence of the day and night cycle, etc. These stressful stimuli have the potential to affect many human physiological systems, triggering physical and biological adaptive changes to re-establish the homeostatic state. A particular concern regards the risks for the effects of spaceflight on the central nervous system (CNS), as several lines of evidence reported a great impact on neuroplasticity, cognitive functions, neurovestibular system, short-term memory, cephalic fluid shift, reduction in motor function, and psychological disturbances, especially during long-term missions. Aside these potential detrimental effects, the other side of the coin reflects the potential benefit of applicating space-related conditions on Earth-based life sciences, as cancer research. Here, we focused on examining the effect of real and simulated microgravity on CNS functions, both in humans and in cellular models, browsing the different techniques to experience or mime microgravity on-ground. Increasing evidence demonstrate that cancer cells, and brain cancer cells in particular, are negatively affected by microgravity, in terms of alteration in cell morphology, proliferation, invasion, migration, and apoptosis, representing an advancing novel side of space-based investigations. Overall, deeper understandings about the mechanisms by which space environment influences CNS and tumor biology may be promisingly translated into many clinical fields, ranging from aerospace medicine to neuroscience and oncology, representing an enormous pool of knowledge for the implementation of countermeasures and therapeutic applications.

Basal serum level of Δ4-androstenedione reflects the ovaries' ability to respond to stimulation in IVF cycles: setting up a new reliable index of both ovarian reserve and response.

PURPOSE: Adequate androgen levels are necessary for regular follicular growth, progression beyond the pre-antral stage, and prevention of follicular atresia. The main purpose of this study was to investigate whether baseline androgen levels had a predictive value on stimulation outcomes in IVF cycles. The secondary purpose was to compare the possible predictive value of androgens with that of already known markers. METHODS: The study included 91 infertile patients aged 30-45 years awaiting the first IVF cycle. All women underwent the same stimulation protocol and the same starting dose of recombinant FSH. As stimulation outcomes, the number of follicles recruited, estradiol and progesterone levels on the day of trigger, the total dose of gonadotropins administered, and the number of oocytes collected were recorded. Multiple linear regression and multivariate logistic regression were used to evaluate the significant predictive value of the variables for response to controlled ovarian stimulation (COS). By studying the reliability of different markers, an attempt was made to develop a single index with the highest predictive value. RESULTS: Pearson's correlation revealed a statistically significant inverse correlation between oocytes collected and age (r = - 0.333, p < 0.001) and a positive correlation with AMH (anti-müllerian hormone) (r = 0.360, p < 0.001), antral follicle count (AFC) (r = 0.639, p < 0.001), and androstenedione (Δ4-A) (r = 0.359, p < 0.001). No significant correlation was reported with FSH (r = - 0.133, p = 0.207) and total testosterone (r = 0.180, p = 0.088). In COS good responders, the G-index (= AMH ng/mL*AFC/Δ4-A ng/dL) revealed a significantly higher level (p < 0.001) than AMH, AFC, and Δ4-A alone. CONCLUSION: Baseline serum Δ4-A, presumably crucial for ensuring a regular follicular growth, is a reliable marker of ovarian response to stimulation. Since the ovarian capacity to respond to gonadotropins does not depend exclusively on the presence of follicles, we suggest a new index, the G-index, able to contemplate both the ovarian reserve and the Δ4-A level.

Effects of Metformin as Add-On Therapy against Glioblastoma: An Old Medicine for Novel Oncology Therapeutics.

BACKGROUND: Glioblastoma is the most aggressive primary brain malignancy in adults, with a poor prognosis of about 14 months. Recent evidence ascribed to metformin (MET), an antihyperglycemic drug, the potential to reduce cancer incidence and progression, but the molecular mechanisms underlying these effects need to be better investigated. METHODS: Here, we tested the efficacy of MET on n = 10 primary glioblastoma endothelial cells (GECs), by viability and proliferation tests, as MTT and Live/Dead assays, apoptosis tests, as annexin V assay and caspase 3/7 activity, functional tests as tube-like structure formation and migration assay and by mRNA and protein expression performed by quantitative real-time PCR analysis (qRT-PCR) and Western Blot, respectively. RESULTS: Data resulting revealed a time- and µ-dependent ability of MET to decrease cell viability and proliferation, increasing pro-apoptotic mechanisms mediated by caspases 3/7. Also, MET impacted GEC functionality with a significant decrease of angiogenesis and invasiveness potential. Mechanistically, MET was able to interfere with sphingolipid metabolism, weakening the oncopromoter signaling promoted by sphingosine-1-phosphate (S1P) and shifting the balance toward the production of the pro-apoptotic ceramide. CONCLUSIONS: These observations ascribed to MET the potential to serve as add-on therapy against glioblastoma, suggesting a repurposing of an old, totally safe and tolerable drug for novel oncology therapeutics.

Loss of consciousness in a helicopter pilot as plausible first sign of insulinoma: a case report.

A 50-year-old man who worked as a helicopter rescue pilot transiently lost consciousness while piloting a helicopter rescue. In the diagnostic process, all tests for the main possible differential diagnoses of loss of consciousness (cardiological and neurological) were performed and yielded normal results. Blood chemistry tests revealed recurrent fasting hypoglycemia and Chromogranin A was at the upper limit of normal. Fine needle aspiration guided by endoscopic ultrasonography was used to diagnose insulinoma-type neuroendocrine tumor of the pancreas. According to the Italian policies, the occupational physician aims to maintain professional skills without neglecting flight safety. A careful analysis of the relationship between the characteristics of the state of health of the aviator and his specific work needs was carried out, and he was given the opportunity to continue working as a rescue pilot thanks to medical therapies associated with organizational interventions in the workplace.

Hyperandrogenism and menstrual imbalance are the best predictors of metformin response in PCOS patients.

BACKGROUND: Moving from the correlation between insulin-resistance and PCOS, metformin has been administered in some PCOS women improving ovulatory and metabolic functions and decreasing androgen levels. Inconsistency and unpredictability of response to metformin limit its extensive use. Aim of this study was to identify reliable predictors of response to metformin therapy for weight loss and reduction in plasma androgen levels using ANNs (artificial neural networks). METHODS: One hundred eight consecutive women with PCOS (ESHRE/ASRM 2003 Rotterdam criteria) treated with metformin 1500 mg/day, at inclusion and every 6 months underwent to a complete clinical, endocrine/metabolic assessment and ultrasonographic evaluation. Therapy outcomes were BMI reduction (≥1 kg/m2) in overweight/obese and free-androgen-index (FAI) decrease (≥1%) in hyperandrogenemic women. Semantic connectivity maps (SCMs) were obtained through Auto-CM, a fourth generation ANN, to compare patients' baseline clinical features to the treatment outcomes. Multivariate logistic regression analysis was used to assess the major predictor in drop-out patients and the associated risk. RESULTS: At 6 months 54 out of 103 (52,4%) obese patients showed BMI reduction and 45 out of 89 (50,6%) hyperandrogenemic women showed FAI decrease. The further response rates at 12 months were 30,6 and 47%, respectively. SCMs showed a clear polarization for both the outcomes with elevated accuracy. Treatment responsiveness resulted strictly related to oligo-amenorrhea and hyperandrogenemia at baseline. In addition, lower serum testosterone levels at baseline were found to be the major predictor of treatment discontinuation. CONCLUSIONS: In women with PCOS, menstrual pattern imbalance and ovarian androgens excess are the best predictors of metformin response. They may pave the way for a rethinking of the criteria for evaluating hyperandrogenism in order to better define the large population included in the diagnosis of PCOS. Baseline plasma testosterone level can serve as a sensitive marker to predict treatment compliance.

"Add-Ons" for Assisted Reproductive Technology: Do Patients Get Honest Information from Fertility Clinics' Websites?

"Add-on" procedures are actively promoted on some fertility clinic websites as proven means to improve IVF success rates, especially for couples with repeated implantation/IVF failures. However, the actual contribution of these interventions to live birth rates remains inconclusive. At present, little is known about the type and quality of the information provided on the IVF clinics' websites regarding the merits of "add-ons." A systematic evaluation of the quality of information on "add-on" procedures in fertility clinic websites was performed using 10-criteria structured questionnaire. We included English language websites that presented in the Google.com search engine after typing the following key-words:"endometrial scratching"(ES), "intralipid infusions"(ILI), "assisted hatching"(AHA), "PGT-A," or "PGS". In total, 254 websites were evaluated. In most cases, an accurate description of the "add-on" procedures was provided (78.8%). However, only a minority (12%) reported their undetermined effectiveness. The use of PGT-A was more often encouraged (52.8%) than ES (23.6%) and AHA (16%). The cost was infrequently presented (6.9%). Scientific references were only rarely provided for ILI, versus 12.7% for ES, 4.0% for AHA, and 5.6% for PGT-A. The information entry date was often missing. None of the websites reported the clinic's pregnancy-rate following the "add-on" procedures. Information on "add-ons" available to patients from IVF clinic websites is often inaccurate. This could perpetuate false myths among infertile patients about these procedures and raises concern regarding possible commercial bias. It is imperative that IVF clinic websites will better communicate the associated risks and uncertainties of "add-ons" to prospective patients.

Clinical and Molecular Diagnosis of Beckwith-Wiedemann Syndrome with Single- or Multi-Locus Imprinting Disturbance.

Beckwith-Wiedemann syndrome (BWS) is a clinically and genetically heterogeneous overgrowth disease. BWS is caused by (epi)genetic defects at the 11p15 chromosomal region, which harbors two clusters of imprinted genes, IGF2/H19 and CDKN1C/KCNQ1OT1, regulated by differential methylation of imprinting control regions, H19/IGF2:IG DMR and KCNQ1OT1:TSS DMR, respectively. A subset of BWS patients show multi-locus imprinting disturbances (MLID), with methylation defects extended to other imprinted genes in addition to the disease-specific locus. Specific (epi)genotype-phenotype correlations have been defined in order to help clinicians in the classification of patients and referring them to a timely diagnosis and a tailored follow-up. However, specific phenotypic correlations have not been identified among MLID patients, thus causing a debate on the usefulness of multi-locus testing in clinical diagnosis. Finally, the high incidence of BWS monozygotic twins with discordant phenotypes, the high frequency of BWS among babies conceived by assisted reproductive technologies, and the female prevalence among BWS-MLID cases provide new insights into the timing of imprint establishment during embryo development. In this review, we provide an overview on the clinical and molecular diagnosis of single- and multi-locus BWS in pre- and post-natal settings, and a comprehensive analysis of the literature in order to define possible (epi)genotype-phenotype correlations in MLID patients.

Diagnostic Complexities in a Case of Ovarian Hyperstimulation Syndrome Presented Solely as a Unilateral Massive Hydrothorax.

To describe a rare case of unilateral massive hydrothorax after controlled ovarian stimulation for IVF and to analyze the diagnostic complexities in a patient lacking both risk factors and typical features of ovarian hyperstimulation syndrome (OHSS). We present a case of a 35-year-old woman suffering from primary infertility due to a severe male factor. Admitted to hospital for dyspnea, the patient initially underwent a thoracentesis. Later, due to the recurrence of massive hydrothorax, permanent pleural drainage was placed. Recognized as a severe manifestation of the OHSS, it was treated by pleural drainage, hydration, albumin perfusion, and management of the intercurrent pregnancy, up to improvement in clinical and hematological laboratory parameters and resolution of pleural effusion and respiratory symptoms. A total of 42 l of pleural fluid was drained during the 40 days of hospitalization. Since the pathogenesis of isolated acute hydrothorax in ovarian stimulation probably lies in the presence of anatomical defects of the diaphragm, this may justify that the relationship between this pathology and the OHSS risk factors may be less close. Massive pleural effusion may exceptionally be the only clinical presentation of OHSS. A high index of suspicion is necessary to make the correct diagnosis and to promptly administer treatment.

Frontiers in Anti-Cancer Drug Discovery: Challenges and Perspectives of Metformin as Anti-Angiogenic Add-On Therapy in Glioblastoma.

Glioblastoma is the most common primitive tumor in adult central nervous system (CNS), classified as grade IV according to WHO 2016 classification. Glioblastoma shows a poor prognosis with an average survival of approximately 15 months, representing an extreme therapeutic challenge. One of its distinctive and aggressive features is aberrant angiogenesis, which drives tumor neovascularization, representing a promising candidate for molecular target therapy. Although several pre-clinical studies and clinical trials have shown promising results, anti-angiogenic drugs have not led to a significant improvement in overall survival (OS), suggesting the necessity of identifying novel therapeutic strategies. Metformin, an anti-hyperglycemic drug of the Biguanides family, used as first line treatment in Type 2 Diabetes Mellitus (T2DM), has demonstrated in vitro and in vivo antitumoral efficacy in many different tumors, including glioblastoma. From this evidence, a process of repurposing of the drug has begun, leading to the demonstration of inhibition of various oncopromoter mechanisms and, consequently, to the identification of the molecular pathways involved. Here, we review and discuss metformin's potential antitumoral effects on glioblastoma, inspecting if it could properly act as an anti-angiogenic compound to be considered as a safely add-on therapy in the treatment and management of glioblastoma patients.

Decreased serum level of sphingosine-1-phosphate: a novel predictor of clinical severity in COVID-19.

The severity of coronavirus disease 2019 (COVID-19) is a crucial problem in patient treatment and outcome. The aim of this study is to evaluate circulating level of sphingosine-1-phosphate (S1P) along with severity markers, in COVID-19 patients. One hundred eleven COVID-19 patients and forty-seven healthy subjects were included. The severity of COVID-19 was found significantly associated with anemia, lymphocytopenia, and significant increase of neutrophil-to-lymphocyte ratio, ferritin, fibrinogen, aminotransferases, lactate dehydrogenase (LDH), C-reactive protein (CRP), and D-dimer. Serum S1P level was inversely associated with COVID-19 severity, being significantly correlated with CRP, LDH, ferritin, and D-dimer. The decrease in S1P was strongly associated with the number of erythrocytes, the major source of plasma S1P, and both apolipoprotein M and albumin, the major transporters of blood S1P. Not last, S1P was found to be a relevant predictor of admission to an intensive care unit, and patient's outcome. Circulating S1P emerged as negative biomarker of severity/mortality of COVID-19 patients. Restoring abnormal S1P levels to a normal range may have the potential to be a therapeutic target in patients with COVID-19.

Psychological distress, anger and quality of life in polycystic ovary syndrome: associations with biochemical, phenotypical andsocio-demographic factors.

OBJECTIVE: To investigate the association between polycystic ovary syndrome (PCOS) and psychological disturbances, including anger. To analyze whether the biochemical/phenotypical features of PCOS play a role in the type and severity of psychological disorders. MATERIAL AND METHODS: This case-control study included 30 PCOS patients meeting NIH criteria and 30 non-PCOS women referring to Reproductive Medicine Unit for infertility. Complete clinical and biochemical screening and the self-reported psychological data [Symptom Check List 90-R (SCL-90-R); Short-Form Health Survey 36 (SF-36); and State-Trait Anger Expression Inventory-2 (STAXI-2)] were collected. Statistical analyses were performed with SPSS-21. RESULTS: Compared with control women, women with PCOS reported significantly higher scores on SCL-90-R scales of somatization, anxiety, hostility, psychoticism, overall psychological distress and a number of symptoms. At STAXI-2, patients with PCOS scored higher in trait-anger and in the outward expression of anger, while lower in outward anger-control; PCOS patients had significantly lower scores on SF-36 scales of physical functioning and bodily pain. Hirsutism was directly associated with anxiety. Regarding the associations between phenotypical/biochemical features and psychological distress in PCOS patients, results showed that waist-to-hip ratio is inversely related to anxiety, psychoticism, hostility and to the indexes of psychological distress; such inverse relationship was also seen between plasmatic levels of testosterone and trait-anger, and between total cholesterol and hostility. CONCLUSIONS: Results were consistent with the previous literature on the well-being of PCOS women (in particular for anxiety and quality of life [QoL]) but failed to find evidence for depression. The relationship between psychological distress and the features of the syndrome highlighted the role of hirsutism. With respect to hyperandrogenemia, our data rejected its involvement in the elevated negative mood states and affects. Adopting an interdisciplinary approach in the PCOS patients' care, anger showed to be common and deserves major consideration.

Prolactin and proinflammatory cytokine expression at the fetomaternal interface in first trimester miscarriage.

OBJECTIVE: To investigate the expression of prolactin (PRL), PRL-receptor (PRL-R), and the TH1 cytokines interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) at the maternofetal interface. DESIGN: Case-control study. SETTING: University hospital unit of gynecology and obstetrics and research laboratories. PATIENT(S): Women undergoing suction curettage for spontaneous miscarriage (study group) and voluntary termination of pregnancy (control group) in the first trimester. INTERVENTION(S): Samples of decidua and villi collected and histologically examined at the time of suction curettage. MAIN OUTCOME MEASURE(S): Evaluation of all villous samples for karyotype with only euploid cases included; detection of transcripts of PRL, PRL-R, TNF-α, IFN-γ, and IL-2 by qualitative reverse-transcriptase-polymerase chain reaction (RT-PCR); investigation of pattern and site of expression by immunohistochemistry. RESULT(S): In both groups, PRL-R and IFN-γ were broadly expressed. The expression of PRL was impaired or absent in the villi of the study group compared with controls. Expression of TNF-α was reduced, although not statistically significantly, in both decidual and villous samples of the study group. Immunohistochemical analysis showed the lack of IL-2 expression in decidual specimens of the control group versus the full expression shown in the study group. CONCLUSION(S): Our results highlight the correspondence between PRL expression and vital pregnancy and the involvement of the TH1 cytokines with different specific roles at the implantation site. Prolactin and IL-2 may reciprocally influence expression.
