RESUMO

BACKGROUND: Literature is lacking strong evidence about comparisons of efficacy and quality of life-related outcomes between laparoscopic total and/or supracervical hysterectomy (LTH/LSCH) with laparoscopic sacrocolpopexy (LSC) and minimally invasive sacrohysteropexy (LSH). OBJECTIVE: To summarize and compare available data on this topic providing a useful clinical tool in the treatment decision process. SEARCH STRATEGY: We performed a systematic research of PubMed (MEDLINE), Web of Science, and Gooogle Scholar. SELECTION CRITERIA: We included studies that compared at least one efficacy outcome (objective or subjective outcome) between LTH/LSCH with LSC and LSH. Data on surgery-related morbidities were also extracted where available. DATA COLLECTION AND ANALYSIS: A random-effect meta-analysis was conducted reporting pooled mean differences and odds ratios (OR) between groups using Review Manager V.7.9.0. MAIN RESULTS: We included a total of nine observational studies. LTH/LSCH with LSH was associated with a significantly higher objective success (apical compartment OR 7.95; 95% confidence interval [CI] 2.23-28.33; I2 = 0%; P = 0.001; anterior compartment OR 2.23; 95% CI 1.26-4.30; I2 = 12%; P = 0.007) and subjective success (OR 3.19; 95% CI 1.42-7.17; I2 = 39%; P = 0.005). No differences were found regarding intraoperative and postoperative complications, sexual dysfunction, and stress urinary incontinence rate after surgery. Hysteropexy showed shorter operative time and shorter hospital length with a pool mean difference of 27.37 min (95% CI 18.04-32.71; I2 = 0%; P < 0.001) and 0.7 days (95% CI 0.24-1.17; I2 = 75%; P = 0.003), respectively. Concurrent hysterectomy was not associated with a higher rate of mesh-related complications (P = 0.53). No major differences were found regarding recurrence and reoperation rate (P = 0.10 and P = 0.93, respectively). CONCLUSIONS: LTH/LSCH with LSC has better objective and subjective outcomes in pelvic organ prolapse surgery than LSH alone, especially for apical and anterior compartments, and is not associated with higher postoperative sexual dysfunction and mesh-related complications. Adequate preoperative counseling is highly recommended in patients who desire uterine preservation. PROSPERO REGISTRATION NUMBER: CRD42024537270.

RESUMO

BACKGROUND: Despite evidence showing a connection between inflammation and endometrial cancer (EC) risk, the surveys on genetic correlation and cohort studies investigating the impact on long-term outcomes have yet to be refined. We aimed to address the impact of inflammation factors on the pathogenesis, progression and consequences of EC. METHODS: For the genetic correlation analyses, a two-sample of Mendelian randomization (MR) study was applied to investigate inflammation-related single-nucleotide polymorphisms involved with endometrial cancer from GWAS databases. The observational retrospective study included consecutive patients diagnosed with EC (stage I to IV) with surgeries between January 2010 and October 2020 at the Cancer Hospital of Shantou University Medical College. RESULTS: The 2-sample MR surveys indicated no causal relationship between inflammatory cytokines and endometrial cancer. 780 cases (median age, 55.0 years ) diagnosed with EC were included in the cohort and followed up for an average of 6.8 years. Increased inflammatory parameters at baseline were associated with a higher FIGO stage and invasive EC risk (odds ratios [OR] 1.01 to 4.20). Multivariate-cox regression suggested that multiple inflammatory indicators were significantly associated with overall survival (OS) and progression-free survival (PFS) (P < 0.05). Nomogram models based on inflammatory risk and clinical factors were developed for OS and PFS with C-index of 0.811 and 0.789, respectively. LASSO regression for the validation supported the predictive efficacy of inflammatory and clinical factors on the long-term outcomes of EC. CONCLUSIONS: Despite the fact that the genetic surveys did not show a detrimental impact of inflammatory cytokines on the endometrial cancer risk, our cohort study suggested that inflammatory level was associated with the progression and long-term outcomes of EC. This evidence may contribute to new strategies targeted at decreasing inflammation levels during EC therapy.

RESUMO

Adipose-derived stem cells (ADSCs) are promising in regenerative medicine. Their proliferation, survival and activation are influenced by specific signals within their microenvironment, also known as niche. The stem cell niche is regulated by complex interactions between multiple cell types. When transplanted in a specific area, ADSCs can secrete several immunomodulatory factors. At the same time, a tumor microenvironment can influence stem cell behavior, modulating proliferation and their ability to differentiate into a specific phenotype. Whitin this context, we exposed ADSCs to plasma samples derived from human patients diagnosed with prostate cancer (PC), or precancerous lesions (PL), or benign prostatic hyperplasia (BPH) for 4, 7 or 10 days. We then analyzed the expression of main stemness-related markers and cell-cycle regulators. We also measured cytokine production and polyamine secretion in culture medium and evaluated cell morphology and collagen production by confocal microscopy. The results obtained from this study show significant changes in the morphology of ADSCs exposed to plasma samples, especially in the presence of prostate cancer plasma, suggesting important implications in the use of ADSCs for the development of new treatments and application in regenerative medicine.

RESUMO

OBJECTIVE: To investigate the safety of sentinel node mapping for patients with early-stage cervical cancer undergoing cervical conization plus nodal evaluation. METHODS: The ETERNITY project is a retrospective, multi-institutional study collecting data of patients with early-stage cervical cancer undergoing fertility-sparing treatment. Here, we compared outcomes related to three methods of nodal assessment: sentinel node mapping (SNM), SNM plus backup lymphadenectomy (SNM + LND); pelvic lymphadenectomy (LND). RESULTS: Charts of 123 patients (with stage IA1-IB1 cervical cancer) were evaluated. Median patients' age was 34 (range, 22-44) years. SNM, SNM + LND, and LND were performed in 32 (26 %), 31 (25.2 %), and 60 (48.8 %) patients, respectively. Overall, eight (6.5 %) patients were diagnosed with positive nodes. Two (3.3 %), three (9.7 %), and three (9.4 %) patients were detected in patients who had LND, SNM + LND, and SNM respectively. Considering the 63 patients undergoing SNM (31 SNM + LND and 32 SNM alone), macrometastases, micrometastases, and isolated tumor cells were detected in four (3.2 %), three (2.4 %), and one (0.8 %) patients, respectively. All patients with positive nodes discontinued the fertility sparing treatment. Other two patients (one (1.7 %) in the LND group and one (3.1 %) in the SNM group) required hysterectomy even after negative nodal evaluation. After a median follow-up of 53.6 (range, 1.3, 158.0) months, nine (7.3 %) and two (1.6 %) patients developed cervical and pelvic nodes recurrences, respectively. Disease-free (p = 0.332, log-rank test) and overall survival (p = 0.769, log-rank test) were similar among groups. CONCLUSIONS: In this retrospective experience, SNM upholds long-term oncologic effectiveness of LND, reducing morbidity.

RESUMO

BACKGROUND: Although hysteroscopy with endometrial biopsy is the gold standard in the diagnosis of endometrial pathology, the gynecologist experience is crucial for a correct diagnosis. Deep learning (DL), as an artificial intelligence method, might help to overcome this limitation. Unfortunately, only preliminary findings are available, with the absence of studies evaluating the performance of DL models in identifying intrauterine lesions and the possible aid related to the inclusion of clinical factors in the model. AIM: To develop a DL model as an automated tool for detecting and classifying endometrial pathologies from hysteroscopic images. METHODS: A monocentric observational retrospective cohort study was performed by reviewing clinical records, electronic databases, and stored videos of hysteroscopies from consecutive patients with pathologically confirmed intrauterine lesions at our Center from January 2021 to May 2021. Retrieved hysteroscopic images were used to build a DL model for the classification and identification of intracavitary uterine lesions with or without the aid of clinical factors. Study outcomes were DL model diagnostic metrics in the classification and identification of intracavitary uterine lesions with and without the aid of clinical factors. RESULTS: We reviewed 1500 images from 266 patients: 186 patients had benign focal lesions, 25 benign diffuse lesions, and 55 preneoplastic/neoplastic lesions. For both the classification and identification tasks, the best performance was achieved with the aid of clinical factors, with an overall precision of 80.11%, recall of 80.11%, specificity of 90.06%, F1 score of 80.11%, and accuracy of 86.74 for the classification task, and overall detection of 85.82%, precision of 93.12%, recall of 91.63%, and an F1 score of 92.37% for the identification task. CONCLUSION: Our DL model achieved a low diagnostic performance in the detection and classification of intracavitary uterine lesions from hysteroscopic images. Although the best diagnostic performance was obtained with the aid of clinical data, such an improvement was slight.

RESUMO

Background: The contribution of gut microbiota to the pathogenesis of polycystic ovary syndrome (PCOS) is controversial. The causal relationship to this question is worth an in-depth comprehensive of known single nucleotide polymorphisms associated with gut microbiota. Methods: We conducted bidirectional Mendelian randomization (MR) utilizing instrumental variables associated with gut microbiota (N = 18,340) from MiBioGen GWAS to assess their impact on PCOS risk in the FinnGen GWAS (27,943 PCOS cases and 162,936 controls). Two-sample MR using inverse variance weighting (IVW) was undertaken, followed by the weighted median, weighted mode, and MR-Egger regression. In a subsample, we replicated our findings using the meta-analysis PCOS consortium (10,074 cases and 103,164 controls) from European ancestry. Results: IVWMR results suggested that six gut microbiota were causally associated with PCOS features. After adjusting BMI, SHBG, fasting insulin, testosterone, and alcohol intake frequency, the effect sizes were significantly reduced. Reverse MR analysis revealed that the effects of PCOS features on 13 gut microbiota no longer remained significant after sensitivity analysis and Bonferroni corrections. MR replication analysis was consistent and the results suggest that gut microbiota was likely not an independent cause of PCOS. Conclusion: Our findings did not support the causal relationships between the gut microbiota and PCOS features at the genetic level. More comprehensive genome-wide association studies of the gut microbiota and PCOS are warranted to confirm their genetic relationship. Declaration: This study contains 3533 words, 0 tables, and six figures in the text as well as night supplementary files and 0 supplementary figures in the Supplementary material.

RESUMO

OBJECTIVE: To date, no data supports the execution of vaccination after hysterectomy for high-grade cervical intraepithelial neoplasia (CIN2+) and early-stage cervical cancer. We aim to evaluate the potential effect of vaccination after hysterectomy for high-grade cervical intraepithelial neoplasia and early-stage cervical cancer. METHODS: This is a multi-center retrospective study evaluating data of women who develop lower genital tract dysplasia (including anal, vulvar and vaginal intra-epithelial neoplasia) after having hysterectomy for CIN2+ and FIGO stage IA1- IB1 cervical cancer. RESULTS: Overall, charts for 77 patients who developed lower genital tract dysplasia were collected. The study population included 62 (80.5%) and 15 (19.5%) patients with CIN2+ and early-stage cervical cancer, respectively. The median (range) time between hysterectomy and diagnosis of develop lower genital tract dysplasia was 38 (range, 14-62) months. HPV types covered by the nonavalent HPV vaccination would potentially cover 94.8% of the development of lower genital tract dysplasia. Restricting the analysis to the 18 patients with available HPV data at the time of hysterectomy, the beneficial effect of nonvalent vaccination was 89%. However, considering that patients with persistent HPV types (with the same HPV types at the time of hysterectomy and who developed lower genital tract dysplasia) would not benefit from vaccination, we estimated the potential protective effect of vaccination to be 67% (12 out of 18 patients; four patients had a persistent infection for the same HPV type(s)). CONCLUSIONS: Our retrospective analysis supported the adoption of HPV vaccination in patients having treatment for HPV-related disease. Even in the absence of the uterine cervix, HPV vaccination would protect against develop lower genital tract dysplasia. Further prospective studies have to confirm our preliminary research.

RESUMO

Amniotic fluid is essential for fetus wellbeing and is used to monitor pregnancy and predict fetal outcomes. Sex affects health and medicine from the beginning of life, but knowledge of its influence on cell-depleted amniotic fluid (AF) and amniotic fluid cells (AFCs) is still neglected. We evaluated sex-related differences in AF and in AFCs to extend personalized medicine to prenatal life. AFCs and AF were obtained from healthy Caucasian pregnant women who underwent amniocentesis at the 16th-18th week of gestation for advanced maternal age. In the AF, inflammation biomarkers (TNFα, IL6, IL8, and IL4), malondialdehyde, nitrites, amino acids, and acylcarnitines were measured. Estrogen receptors and cell fate (autophagy, apoptosis, senescence) were measured in AFCs. TNFα, IL8, and IL4 were higher in female AF, whereas IL6, nitrites, and MDA were similar. Valine was higher in male AF, whereas several acylcarnitines were sexually different, suggesting a mitochondrial involvement in establishing sex differences. Female AFCs displayed higher expression of ERα protein and a higher ERα/ERß ratio. The ratio of LC3II/I, an index of autophagy, was higher in female AFCs, while LC3 gene was similar in both sexes. No significant sex differences were found in the expression of the lysosomal protein LAMP1, while p62 was higher in male AFCs. LAMP1 gene was upregulated in male AFCs, while p62 gene was upregulated in female ones. Finally, caspase 9 activity and senescence linked to telomeres were higher in female AFCs, while caspase 3 and ß-galactosidase activities were similar. This study supports the idea that sex differences start very early in prenatal life and influence specific parameters, suggesting that it may be relevant to appreciate sex differences to cover knowledge gaps. This might lead to improving the diagnosis of risk prediction for pregnancy complications and achieving a more satisfactory monitoring of fetus health, even preventing future diseases in adulthood.

RESUMO

Mesenchymal stem cells are undifferentiated cells able to acquire different phenotypes under specific stimuli. Wharton's jelly is a tissue in the umbilical cord that contains mesenchymal stromal cells (MSCs) with a high plasticity and differentiation potential. Their regeneration capability is compromised by cell damage and aging. The main cause of cell damage is oxidative stress coming from an imbalance between oxidant and antioxidant species. Microgravity represents a stressing condition able to induce ROS production, ultimately leading to different subcellular compartment damages. Here, we analyzed molecular programs of stemness (Oct-4; SOX2; Nanog), cell senescence, p19, p21 (WAF1/CIP1), p53, and stress response in WJ-MSCs exposed to microgravity. From our results, we can infer that a simulated microgravity environment is able to influence WJ-MSC behavior by modulating the expression of stress and stemness-related genes, cell proliferation regulators, and both proapoptotic and antiapoptotic genes. Our results suggest a cellular adaptation addressed to survival occurring during the first hours of simulated microgravity, followed by a loss of stemness and proliferation capability, probably related to the appearance of a molecular program of senescence.

RESUMO

OBJECTIVE: Accumulating evidence suggested the detrimental effects of adopting minimally invasive surgery in the management of early-stage cervical cancer. However, long-term evidence on the role of minimally invasive radical hysterectomy in "low-risk" patients exists. METHODS: This is multi-institutional retrospective study comparing minimally invasive and open radical hysterectomy in low-risk early-stage cervical cancer patients. A propensity-score matching algorithm (1:2) was used to allocate patients into the study groups. Kaplan-Meir model was used to estimate 10-year progression-free and overall survival. RESULTS: Charts of 224 "low-risk" patients were retrieved. Overall, 50 patients undergoing radical hysterectomy were matched with 100 patients undergoing open radical hysterectomy. Minimally invasive radical hysterectomy was associated with a longer median operative time (224 (range, 100-310) vs. 184 (range, 150-240) minutes; p < 0.001), lower estimated blood loss (10 (10-100) vs. 200 (100-1000) ml, p < 0.001), and shorter length of hospital stay (3.8 (3-6) vs. 5.1 (4-12); p < 0.001). Surgical approach did not influence the risk of having intra-operative (4% vs. 1%; p = 0.257) and 90-day severe (grade 3+) postoperative complication rates (4% vs. 8%; p = 0.497). Ten-year disease-free survival was similar between groups (94% vs. 95%; p = 0.812; HR:1.195; 95%CI:0.275, 5.18). Ten-year overall survival was similar between groups (98% vs. 96%; p = 0.995; HR:0.994; 95%CI:0.182, 5.424). CONCLUSIONS: Our study appears to support emerging evidence suggesting that, for low-risk patients, laparoscopic radical hysterectomy does not result in worse 10-year outcomes compared to the open approach. However, further research is needed and open abdominal radical hysterectomy remains the standard treatment for cervical cancer patients.

RESUMO

Primary mucosal melanomas (MMs) are uncommon tumors originating from melanocytes located in the mucous membranes at various anatomic sites within the body. MM significantly differs from cutaneous melanoma (CM) regarding epidemiology, genetic profile, clinical presentation, and response to therapies. Despite these differences, that have important implications for both disease diagnosis and prognosis, MMs are usually treated in the same way as CM but exhibit a lower response rate to immunotherapy leading to a poorer survival rate. Furthermore, a high inter-patient variability can be observed in relation to therapeutic response. Recently, novel "omics" techniques have evidenced that MM lesions have different genomic, molecular, and metabolic landscapes as compared with CM lesions, thus explaining the heterogeneity of the response. Such specific molecular aspects might be useful to identify new biomarkers aimed at improving the diagnosis and selection of MM patients who could benefit from immunotherapy or targeted therapy. In this review, we have focused on relevant molecular and clinical advancements for the different MM subtypes in order to describe the updated knowledge relating to main diagnostic, clinical, and therapeutic implications as well as to provide hints on likely future directions.

RESUMO

The objective of this work is to assess the 5-year outcomes of patients undergoing conization for high-grade cervical lesions that simultaneously present as risk factors in the persistence of HPV infection and the positivity of surgical resection margins. This is a retrospective study evaluating patients undergoing conization for high-grade cervical lesions. All patients included had both positive surgical margins and experienced HPV persistence at 6 months. Associations were evaluated with Cox proportional hazard regression and summarized using hazard ratio (HR). The charts of 2966 patients undergoing conization were reviewed. Among the whole population, 163 (5.5%) patients met the inclusion criteria, being at high risk due to the presence of positive surgical margins and experiencing HPV persistence. Of 163 patients included, 17 (10.4%) patients developed a CIN2+ recurrence during the 5-year follow-up. Via univariate analyses, diagnosis of CIN3 instead of CIN2 (HR: 4.88 (95%CI: 1.10, 12.41); p = 0.035) and positive endocervical instead of ectocervical margins (HR: 6.44 (95%CI: 2.80, 9.65); p < 0.001) were associated with increased risk of persistence/recurrence. Via multivariate analyses, only positive endocervical instead of ectocervical margins (HR: 4.56 (95%CI: 1.23, 7.95); p = 0.021) were associated with worse outcomes. In this high-risk group, positive endocervical margins is the main risk factor predicting 5-year recurrence.

RESUMO

The aim of the present systematic review and meta-analysis was to compare native tissue repair (NTR) against transvaginal mesh augmentation for the repair of anterior vaginal prolapse. A total of 2289 articles were found but only 27 (24.8 %) were included in the review. Guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) were followed to guide the process of the systematic review and meta-analysis. The quality of the observational studies was evaluated according to the Scottish Intercollegiate Guidelines Network, whereas the quality of randomized control trials (RCT) was assessed by the Cochrane risk-of-bias scale. The mesh repair intervention was associated with a higher anatomical cure rate in comparison with NTR repair when the follow-up was ≤24 months [pooled risk difference (95 % CI): -0.18 % (-0.22 %; 0.13 %); p-value: <0.0001; I2: 36.0 %]. Studies reporting anatomical failure had similar findings [pooled risk difference (95 % CI): 0.17 % (0.01 %; 0.33 %); p-value: 0.03; I2: 88.6 %]. No differences in the risk of re-operation were observed between NTR repair and mesh augmentation. Pooled risk differences in the incidence of post-surgical and late complications were higher for the mesh repair intervention [-0.05 % (95 % CI: -0.10 %; 0.00 %) p-value: 0.05; I2: 68.3 %] [-0.05 % (95 % CI: -0.14 %; 0.03 %) p-value: 0.25; I2: 82.0 %]. Women who underwent mesh repair reported greater satisfaction than women who underwent NTR [pooled risk difference (95 % CI): -0.07 % (-0.16 %; 0.02 %); p-value: 0.15; I2: 65.3 %]. In conclusion, mesh repair surgery had higher anatomical cure and satisfaction rates, with no differences in re-operation rate, but had higher post-surgical and late complications in comparison with NTR.

RESUMO

BACKGROUND: In endometrial carcinoma (EC) patients, sentinel lymph node (SLN) biopsy has shown the potential to reduce post-operative morbidity and long-term complications, and to improve the detection of low-volume metastasis through ultrastaging. However, while it has shown high sensitivity and feasibility in low-risk EC patient groups, its role in high-risk groups is still unclear. AIM: To assess the role of SLN biopsy through the cervical injection of indocyanine green (ICG) in high-risk groups of early-stage EC patients. MATERIALS AND METHODS: Seven electronic databases were searched from their inception to February 2021 for studies that allowed data extraction about detection rate and accuracy of SLN biopsy through the cervical injection of ICG in high-risk groups of early-stage EC patients. We calculated pooled sensitivity, false negative (FN) rate, detection rate of SLN per hemipelvis (DRh), detection rate of SLN per patients (DRp), and bilateral detection rate of SLN (DRb), with 95% confidence interval (CI). RESULTS: Five observational cohort studies (three prospective and two retrospective) assessing 578 high risk EC patients were included. SLN biopsy sensitivity in detecting EC metastasis was 0.90 (95% CI: 0.03-0.95). FN rate was 2.8% (95% CI: 0.6-11.6%). DRh was 88.4% (95% CI: 86-90.5%), DRp was 96.6% (95% CI: 94.7-97.8%), and DRb was 80% (95% CI: 75.4-83.9). CONCLUSION: SLN biopsy through ICG cervical injection may be routinely adopted instead of systematic pelvic and para-aortic lymphadenectomy in surgical staging for high-risk groups of early-stage EC patients, as well as in low-risk groups.

RESUMO

Background: The mucosal high-risk (HR) human papillomavirus (HPV) is associated with oropharyngeal carcinogenesis. Aims of this study were to evaluate the prevalence of HR-HPV infection in laryngeal squamous cell carcinoma (LSCC) from different subsites, and the clinico-biological meaning of p16 overexpression. Methods: Ninety-seven LSCCs submitted to primary surgery (n = 75) or to post-irradiation salvage laryngectomy (n = 22) were evaluated for HR-HPV DNA and RNA using Luminex-based assays. p16 immunohistochemistry was performed. Results: HR-HPV DNA from HPV16 was detected in seven cases (8.75%), without significant differences between supraglottic and glottic lesions. HPV RNA was never detected. p16 overexpression correlated with HR-HPV DNA, but the kappa agreement score was poor. HPV DNA showed no impact on prognosis. p16 overexpression was associated with a better survival (OS, RFS) in primarily operated cases, while an inverse association with OS was observed in the salvage surgery group. Conclusions: HR-HPV infection appears to have a marginal role in LSCC independent of the anatomical subsite. p16 expression is deregulated in LSCC independent of HPV but displays a prognostic role in patients submitted to primary surgery. The negative predictive role of p16 overexpression in patients undergoing salvage surgery deserves more investigations for validation and elucidation of its clinical relevance.

RESUMO

INTRODUCTION: to assess incidence, prognosis and obstetric outcome of patients treated for gestational trophoblastic disease GTD in a twenty-year period. Incidence, prognosis and obstetric outcome of gestational throphoblastic disease. METHODS: retrospective study. RESULTS: Fifty-four cases of GTD: 46 (85.18%) cases of Hydatidiform mole (HM); 8 cases of Persistent Gestational Trophoblastic Neoplasia (GTN) (14.81%): 6/8 cases (75%) GTN not metastatic; 2/8 cases (25%) GTN metastatic. In both cases, the metastases occurred in the lungs. In 3 out of 8 GTN cases (37.5%) a histological picture of choriocarcinoma emerged. The incidence of GTD cases treated from 2000 to 2020 was 1.8 cases per 1000 deliveries and 1.3 cases per 1000 pregnancies. Of the 54 patients, 30 (55.56%) presented showed normal serum hCG levels without the need for chemotherapy. On the other hand, 24 patients (44.44%) developed a persistent trophoblastic disease and underwent adjuvant therapy. The negative prognostic factors that affected the risk of persistence of GTD were: serum hCG levels at diagnosis > 100,000 mUI/ml; characteristic "snow storm" finding at the ultrasound diagnosis; a slow regression of serum hCG levels during follow-up; the persistence of high serum hCG levels (especially if > 1000 mUI/ml one month after suction curettage) that was the main risk factor for resistance to first-line chemotherapy. There were 10 pregnancies in total following treatment. Patients' survival in our study was 100%. DISCUSSION: Although GTD is a rare disease, its incidence was 1.3 cases per 1,000 pregnancies in Sardinia, Italy, higher if compared with mean national and worldwide incidence.

RESUMO

In the last decade, a growing attention has been focused on identifying effective therapeutic strategies also in the orphan clinical setting of women with platinum-resistant disease. In this context, secondary cytoreductive surgery (SCS) remains a potential approach only in women with platinum sensitive relapse, but experimental data have been published supporting the role of SCS also in patients with platinum-resistant recurrence. In particular, surgery is emerging as a potential option in specific subgroups of women, such as those patients with low-grade serous histology, or low-volume relapse with disease located in the so-called pharmacological sanctuaries. Furthermore, contrasting evidences have suggested a potential role in this clinical setting of SCS combined with intraperitoneal hyperthermic chemotherapy. In this complex scenario we review here the available evidences regarding the role surgery in ovarian cancer patients with platinum resistant disease, trying also to understand which patients may benefit from this challenging, experimental approach.

RESUMO

PURPOSE: Paracetamol is the only drug recommended to treat fever in neonates. At recommended doses, paracetamol has not been associated with liver injury in neonates, while hepatotoxicity may occur after intake of a single high dose or multiple excessive doses. The aim of this narrative review is to critically analyze and summarize the available literature on newborns and infants exposed to supratherapeutic doses of paracetamol, with special focus on their clinical features, outcome, and management. METHODS: The PubMed, SCOPUS, and Google Scholar search engines were used to collect data, without time limitation. The following keywords were used: paracetamol/acetaminophen, overdose, hepatotoxicity, N-acetylcysteine, newborn, infant. RESULTS: The literature search identified a total of 27 case reports, a number of review articles, and few other relevant publications. Neonatal poisoning from paracetamol resulted from transplacental drug transfer after maternal overdose in some published cases, while it was the consequence of medication errors in other cases. Newborns and infants who have received a single overdose and have paracetamol concentrations below the Rumack-Matthew nomogram limits are at low risk of serious hepatic damage, while those who have recently ingested more than one supratherapeutic dose of paracetamol should be managed with caution. The treatment of choice for paracetamol poisoning is N-acetylcysteine, a specific antidote which reduces paracetamol hepatotoxic effects. N-Acetylcysteine should be given according to specific regimens through weight-based dosing tables. CONCLUSIONS: Caution should be used when paracetamol is administered to the newborn. In the event of an overdose, careful patient monitoring and personalization of post-overdose procedures are recommended.

RESUMO

Aim of this report is to alert clinicians about the potential significant sequelae of administering depot gonadotropin-releasing hormone agonists (GnRHa) shortly after oocytes cryopreservation. In our case report, a 28-year-old nulligravid Caucasian woman diagnosed with breast cancer underwent controlled ovarian stimulation-oocyte cryopreservation before chemotherapy. The oocyte retrieval was performed without complications and the woman was discharged after five hours. Three days later, the patient self-injected depot-GnRHa as chemoprotective agent, as indicated by the oncologist. The next day, the patient referred to the emergency room and she was diagnosed with ovarian hyperstimulation syndrome (OHSS) and required inpatient care. As a consequence, the start of the chemotherapy was delayed by two weeks. In conclusion, chemoprotection with depot-GnRHa after oocyte/embryo cryopreservation is not exempt from risks. The timing for depot-GnRHa administration should be established by the agreement between oncologist and gynecologist in order to avoid the risk of OHSS.

RESUMO

Wharton jelly mesenchymal stem cells (WJ-MSCs) are able to differentiate into different cell lineages upon stimulation. This ability is closely related to the perfect balance between the pluripotency-related genes, which control stem-cell proliferation, and genes able to orchestrate the appearance of a specific phenotype. Here we studied the expression of stemness-related genes, epigenetic regulators (DNMT1, SIRT1), miRNAs (miR-145, miR-148, and miR-185) related to stemness, exosomes, the cell-cycle regulators p21 (WAF1/CIP1) and p53, and the senescence-associated genes (p16, p19, and hTERT). Cells were cultured in the presence or absence of the human hepatocarcinoma cell line HepG2-exhausted medium, to evaluate changes in stemness, differentiation capability, and senescence sensibility. Our results showed the overexpression of SIRT1 and reduced levels of p21 mRNA. Moreover, we observed a downregulation of DNMT1, and a simultaneous overexpression of Oct-4 and c-Myc. These findings suggest that WJ-MSCs are more likely to retain a stem phenotype and sometimes to switch to a highly undifferentiable proliferative-like behavior if treated with medium exhausted by human HepG2 cell lines.
