RESUMEN
OBJECTIVE: Ovarian clear cell carcinoma has a poor prognosis in comparison with other pathological types of epithelial ovarian carcinoma. It also has relative resistance to first-line platinum-based chemotherapy with a great risk of recurrence. CASE REPORT: We report a case of recurrent ovarian clear cell carcinoma status after left salpingo-oophorectomy (fertility-sparing debulking operation) and six courses of adjuvant chemotherapy (paclitaxel (175 mg/m2)/carboplatin (AUC 6)). However, two years after diagnosis, elevated CA-125 accompanied by an intrapelvic mass was noted. Uterine intramural recurrence was found during the second laparotomy. She was treated with right salpingo-oophorectomy and abdominal hysterectomy combined with systemic chemotherapy administration (paclitaxel (175 mg/m2)/carboplatin (AUC 6)) and maintenance therapy (bevacizumab (7.5 mg/kg)). There was no other recurrence until one and a half years postoperatively, and the patient was tumor free with regular follow-up. CONCLUSION: In young patients with stage I ovarian clear cell carcinoma, fertility-sparing surgery was considered. Most patients will suffer from tumor recurrence, and also intrauterine recurrence rarely happen.

Frozen-thawed embryo transfer (FET) has been a viable alternative to fresh embryo transfer in recent years because of the improvement in vitrification methods. Laboratory-based studies indicate that complex molecular and morphological changes in endometrium during the window of implantation after exogenous hormones with controlled ovarian stimulation may alter the interaction between the embryo and endometrium, leading to a decreased implantation potential. Based on the results obtained from randomized controlled studies, increased pregnancy rates and better perinatal outcomes have been reported following FET. Compared to fresh embryo transfer, fewer preterm deliveries, and reduced incidence of ovarian hyperstimulation syndrome were found after FETs, yet there is a trend of increased pregnancy-related hypertensive diseases in women receiving FET. Despite the increased application of FET, the search for the most optimal priming protocol for the endometrium is still undergoing. Three available FET protocols have been proposed to prepare the endometrium: i) natural cycle (true natural cycle and modified natural cycle) ii) artificial cycle (AC) or hormone replacement treatment cycle iii) mild ovarian stimulation (mild-OS) cycle. Emerging evidence suggests that the optimal timing for FET using warmed blastocyst transfer is the LH surge+6 day, hCG administration+7 day, and the progesterone administration+6 day in the true natural cycle, modified natural cycle, and AC protocol, respectively. Although still controversial, better clinical pregnancy rates and live birth rates have been reported using the natural cycle (true natural cycle/modified natural cycle) compared with the AC protocol. Additionally, a higher early pregnancy loss rate and an increased incidence of gestational hypertension have been found in FETs using the AC protocol because of the lack of a corpus luteum. Although the common clinical practice is to employ luteal phase support (LPS) in natural cycles and mild-OS cycles for FET, the requirement for LPS in these protocols remains equivocal. Recent findings obtained from RCTs do not support the routine application of endometrial receptivity testing to optimize the timing of FET. More RCTs with rigorous methodology are needed to compare different protocols to prime the endometrium for FET, focusing not only on live birth rate, but also on maternal, obstetrical, and neonatal outcomes.

Early pregnancy is a complex and well-orchestrated differentiation process that involves all the cellular elements of the fetal-maternal interface. Aberrant trophoblast-decidual interactions can lead to miscarriage and disorders that occur later in pregnancy, including preeclampsia, intrauterine fetal growth restriction, and preterm labor. A great deal of research on the regulation of implantation and placentation has been performed in a wide range of species. However, there is significant species variation regarding trophoblast differentiation as well as decidual-specific gene expression and regulation. Most of the relevant information has been obtained from studies using mouse models. A comprehensive understanding of the physiology and pathology of human implantation and placentation has only recently been obtained because of emerging advanced technologies. With the derivation of human trophoblast stem cells, 3D-organoid cultures, and single-cell analyses of differentiated cells, cell type-specific transcript profiles and functions were generated, and each exhibited a unique signature. Additionally, through integrative transcriptomic information, researchers can uncover the cellular dysfunction of embryonic and placental cells in peri-implantation embryos and the early pathological placenta. In fact, the clinical utility of fetal-maternal cellular trafficking has been applied for the noninvasive prenatal diagnosis of aneuploidies and the prediction of pregnancy complications. Furthermore, recent studies have proposed a viable path toward the development of therapeutic strategies targeting placenta-enriched molecules for placental dysfunction and diseases.
RESUMEN
Cannabidiol (CBD) is an active natural compound that is extracted from Cannabis sativa. Previous studies show that CBD is a nonpsychotropic compound with significant anticancer effects. This study determines its cytotoxic effect on oral cancer cells and OEC-M1 cells and compares the outcomes with a chemotherapeutic drug, cisplatin. This study has investigated the effect of CBD on the viability, apoptosis, morphology, and migration of OEC-M1 cells. Electric cell-substrate impedance sensing (ECIS) is used to measure the change in cell impedance for cells that are treated with a series concentration of CBD for 24 h. AlamarBlue and annexin V/7-AAD staining assays show that CBD has a cytotoxic effect on cell viability and induces cell apoptosis. ECIS analysis shows that CBD decreases the overall resistance and morphological parameters at 4 kHz in a concentration-dependent manner. There is a significant reduction in the wound-healing recovery rate for cells that are treated with 30 µM CBD. This study demonstrates that ECIS can be used for in vitro screening of new chemotherapy and is more sensitive, functional, and comprehensive than traditional biochemical assays. CBD also increases cytotoxicity on cell survival and the migration of oral cancer cells, so it may be a therapeutic drug for oral cancer.

We demonstrate an effective reduction in postmenstrual spotting after our novel hysteroscopic isthmoplasty. This study included 66 patients with isthmocele-related postmenstrual spotting confirmed by sonography and diagnostic hysteroscopy between 2000 and 2017. Our new interventions included the following four steps: (1) make a resection gradient of the distal edge of the isthmocele from the ape of the isthmocele down to the cervical outer orifice; (2) resect the distal and proximal niches of the isthmocele; (3) electrocauterize the distal and proximal sides (not only the niche bottom) of the small cave on the scar side of the isthmocele; (4) manage the isthmocele until it is largely connected to the cavity. In our results, all patients underwent extensive hysteroscopic repair of newly hysteroscopic isthmoplasty without any intra- or postoperative complications. After final hysteroscopic repair modification, prolonged menstrual spotting was significantly decreased in 98.2% (53/54) of the patients, and the total number of bleeding days per menstrual cycle significantly decreased from a mean of 15.38 ± 3.3 days to 6.4 ± 1.9 days postoperatively (p < 0.001). Our four-step hysteroscopic technique successfully resolved prolonged menstrual spotting in over 90% of the patients, exceeding the resolution rates of 60−85% achieved with other hysteroscopic techniques used to treat symptomatic isthmocele. No patients experience recurrence after long-term follow up. Four simple steps led to a significant improvement in bleeding status.
RESUMEN
OBJECTIVE: Cervical pregnancy is a rare type of ectopic pregnancy. When the pregnancy is terminated, it will sometimes lead to persistent bleeding. In some cases, hysterectomy is inevitable and the patient loses fertility. Therefore, early diagnosis and targeted management with systemic or local injection of methotrexate is the first-line treatment. Multiple interventions of cervical pregnancy were used to prevent massive hemorrhage, including dilatation and curettage, laparoscopic resection, hysteroscopic resection combined with uterine artery embolization, or uterine artery clip. CASE REPORT: We report a case of cervical pregnancy with a high beta-hCG level accompanied by a visible fetal heartbeat that was successfully treated with hysteroscopic cervical tissue resection and balloon compression combined with systemic administration of methotrexate. CONCLUSION: Efficacy and safety with preserved fertility were important issues in the management of cervical pregnancy. We provide a safe, simple and effective treatment of cervical pregnancy.

PURPOSE: Some evidence suggests that male infertility increases the risk of cardiovascular diseases (CVDs). However, the evidence in Asian populations is relatively scarce. The aim of this study is to determine whether male infertility increases the risk of CVDs. MATERIALS AND METHODS: We used inpatient and outpatient data for the years 2000 to 2015 from the Taiwanese Longitudinal Health Insurance Database. We enrolled 7,016 males over 18 years old and diagnosed with male infertility. Of these, 2,326 matched our inclusion criteria and were assigned to the study group. For each infertility patient, four comparison patients were frequency-matched by age and index date to form a control cohort comprising 9,304 patients. Cox proportional hazards analysis was used to estimate the association between male infertility and CVDs. RESULTS: After a 15-year follow-up, the incidence rate of CVDs was higher in the infertility group than the control group (1,460.23 and 1,073.70 per 100,000 person-years, respectively). The Cox proportional hazards regression analysis revealed that the adjusted HR for CVDs was 1.472 for the infertility group (95% CI, 1.288-1.683; p<0.001) relative to the control group. The Kaplan-Meier analysis of the cumulative incidence of CVDs in the two groups showed that the cumulative risk curve for CVDs was significantly higher for the infertility group than the control group. CONCLUSIONS: This study shows that men with infertility have a higher risk of developing incident CVDs. In the future, healthcare providers should pay attention to these patients because of their higher health risks.
RESUMEN
OBJECTIVES: To determine the risk of having OSA in a cohort of female subjects who are infertile and the odds of being infertile in women with OSA. PATIENTS AND METHODS: A nationwide, case-control study of female patients 20 years or older diagnosed with female infertility living in Taiwan, from January 1, 2000, through December 31, 2013 (N = 4,078). We identified women who were infertile and created a 2:1 matched control group with women who were not infertile. We used multivariable logistic regression analysis to further estimate the effects of OSA on female infertility. RESULTS: In this 14- year retrospective study, we included 4,078 patients having an initial diagnosis of female infertility. Of those women with infertility, 1.38% had a history of OSA compared with 0.63% of fertile controls (p = 0.002). The mean ages in the study groups were 32.19 ± 6.20 years, whereas the mean ages in the control groups were 32.24 ± 6.37years. Women with OSA had 2.101- times the risk of female infertility compared to women without OSA (p<0.001). CONCLUSION: Our study showed that OSA is more commonly seen in infertile women and increases the odds that a woman will be infertile. More studies need to be done on the whether or not diagnosing and treating OSA can decrease the rate of infertility.

BACKGROUND: Pelvic inflammatory disease (PID) is an important health issue for women. Infection and inflammation play an important role in carcinogenesis and PID has been reported to be associated with ovarian cancer in some small scale studies. AIM: We sought to determine whether PID is associated with an elevated risk of ovarian cancer in Asian women. METHODS: Using data from Taiwan's National Health Insurance Research Database (NHIRD), our retrospective cohort study included women diagnosed with PID (cases) between the years of 2000 till 2012. Each case was matched with two women without PID (controls) by age and the year of first entry into the database. Both study cohorts were followed-up until the first event of ovarian cancer, withdrawal from the NHI program, death, or the end of the study period (December 31, 2012). Cox proportional hazards regression models were used to estimate crude and adjusted hazard ratios (HRs and aHRs) with their corresponding 95% confidence intervals (95% CIs) for the association of PID and ovarian cancer risk, with and without adjusting for potential confounders. RESULTS: During an approximate 10 years of follow-up, cases were significantly more likely than controls to develop ovarian cancer (incidence rates of 0.27 and 0.16 per 1,000 person-years, respectively; P < 0.001). Women with a history of PID had a 1.49-fold elevated risk for ovarian cancer (aHR, 1.49; 95% CI, 1.21-1.84; P < 0.001). CONCLUSION: Our study evidence supports the contention that PID increases the risk of developing ovarian cancer among Taiwanese women. Gynecologists should undertake careful assessments and closely follow patients with PID, who are at long-term risk of developing ovarian cancer. Our findings need further verification in other international cohorts.

OBJECTIVE: Twin-Reversed Arterial Perfusion (TRAP) sequence is a rare complication of monochorionic multiple gestation. Conservative management should be considered if there is no poor prognostic factor. CASE REPORT: This is a 35 year-old female with twin pregnancy with acardiac monster. Under the request of the patient, there was no intervention during the whole pregnancy. We keep regular and close sonography weekly follow up. There was no maternal complication and there was also no heart failure sign or polyhydramnios of the donor twin. Minimal blood flow was noted at the anastomotic vessels under the sonography at late gestational age. Due to breech presentation, cesarean section was performed at gestational age 37 + 1/7 weeks. She delivers a healthy baby smoothly. CONCLUSION: Antenatal sonography is an important tool to evaluate the fetus status. Under special condition, term pregnancy is still possible without any treatment. CASE REPORT: Twin reversed arterial perfusion syndrome in a monochorionic monoamniotic twin pregnancy.

The most common oral cancer is squamous cell carcinoma (SCC) and its highest occurrence is in the tongue. Almost 30% of patients with one primary head and neck tumor will have a second primary malignancy. In recent studies, two novel plant extracts, andrographolide and cannabidiol (CBD), have been exploited for their anticancer effects. Here, we investigated the cytotoxic effects of these two compounds on SCC-25 cells, a human tongue squamous carcinoma cell line, and compared the outcomes with two chemotherapeutic drugs, cisplatin and fluorouracil. Electric cell substrate impedance sensing (ECIS) system was applied to measure frequency- and time-dependent impedance of SCC-25 cell-covered electrodes and to further assess subtle changes in cell morphology and micromotion in response to different concentrations (0, 10, 30, 100, and 300 µM) of these compounds. AlamarBlue and Annexin V/7-AAD binding assays were used to measure the concentration dependent changes in viability and apoptosis of SCC-25 cells. Our results demonstrate that 24 hours after exposure to 30 µM CBD can significantly decrease the micromotion rate, damage the integrity of cell morphology, reduce cell viability, and induce higher apoptosis in treated SCC-25 cells, while the other three drugs attain similar effects at the concentration of 100 µM or higher. The apoptosis-induced changes in cell morphology and micromotion monitored by ECIS correlate well with biochemical assays. Thus, both frequency- and time-dependent impedance measurements using ECIS can be used to real-time follow cancer cell activities in response to anticancer drugs with different temporal cytotoxicity profiles.

BACKGROUND: The incidence of female stroke has increased gradually and has begun occurring at a younger age in recent years. Given that women live longer than men, stroke would cause more negative and longer-term impacts on the rest of the lives of women. There are few related studies on Asian women. We aimed to evaluate stroke risk in Asian women following hypertensive pregnancy disorders. METHODS: Using the Taiwan National Health Insurance database, we designed a retrospective study that included pregnant women between 2000 and 2013. We selected an age-matched control group of women without hypertensive pregnancy disorders at a 1:3 ratio. The endpoint was any episode of stroke; otherwise, the patients were tracked until December 31, 2013. After the index date until the end of 2013, Cox proportional hazards analysis was used to compare the risk of incident stroke. The risk factors for stroke were determined using Cox proportional regression to calculate the hazard ratio (HR) compared with the control group. RESULTS: During the follow-up period, the Kaplan-Meier analysis indicated that patients with hypertensive pregnancy disorders had a significantly higher risk of developing stroke than did patients without hypertensive pregnancy disorders (log-rank test P < 0.001). Multivariate Cox regression analysis demonstrated that the case group had a 2.134-fold increased risk of stroke (HR = 2.134; 95% CI = 1.817-2.505; P < 0.001). CONCLUSION: Our study provided evidence of an increased risk of stroke in patients with hypertensive pregnancy disorders. Compared with those without such disorders, the patients who had experienced the disorders had a 2.134-fold (P < 0.001) higher risk of developing stroke in the future.

BACKGROUND: Pelvic inflammatory disease (PID) is an infectious disease that causes tubal occlusion and other pelvic and abdominal adhesions. The incidence of pelvic inflammatory disease (PID) has increased due to the sexually active status of the young population. This leads to a more serious problem and a larger effect than previously observed. However, there have been few studies on this topic in Asian populations. AIM: We aimed to evaluate the risk of preterm labor and/or ectopic pregnancy in Taiwanese women following PID. DESIGN: Using the Taiwan National Health Insurance Database, we designed a retrospective cohort study that included 12- to 55-year-old pregnant women between 2000 and 2010. We selected a 1:3 age-matched control group of non-PID women. The endpoint was any episode of preterm labor or ectopic pregnancy; otherwise, the patients were tracked until 31 December 2010. METHODS: The risk factors for preterm labor or ectopic pregnancy were explored. For cases included from the index date until the end of 2010, we analyzed the risk of incident preterm labor or ectopic pregnancy. With the use of a multivariate Cox proportional hazard regression analysis, we calculated the hazard ratio (HR) with a 95% CI and compared it with that of the control group. RESULTS: This study examined 30,450 patients with PID and 91,350 controls. During the follow-up period, patients in the PID group were more likely to develop preterm labor or ectopic pregnancy than patients in the control group. The cumulative incidence rates for developing preterm labor were 1.84% (561/30,450 individuals) in patients with PID and 1.63% (1492/91,350 individuals) in patients without PID. On the other hand, the cumulative incidence rate for developing ectopic pregnancy in patients with PID was 0.05% (14/30,450 individuals) but was only 0.04% (33/91,350 individuals) in patients without PID. Compared with those without PID, the patients with PID had a 1.864 times (P<0.001) higher risk of developing preterm labor and a 2.121 times (P = 0.003) higher risk of developing ectopic pregnancy. CONCLUSION: Our study provided evidence of an increased risk of preterm labor or ectopic pregnancy in PID patients.

Silver nanoparticles (AgNPs) enter the central nervous system through the blood-brain barrier (BBB). AgNP exposure can increase amyloid beta (Aß) deposition in neuronal cells to potentially induce Alzheimer's disease (AD) progression. However, the mechanism through which AgNPs alter BBB permeability in endothelial cells and subsequently lead to AD progression remains unclear. This study investigated whether AgNPs disrupt the tight junction proteins of brain endothelial cells, and alter the proteomic metabolism of neuronal cells underlying AD progression in a triple cell coculture model constructed using mouse brain endothelial (bEnd.3) cells, mouse brain astrocytes (ALT), and mouse neuroblastoma neuro-2a (N2a) cells. The results showed that AgNPs accumulated in ALT and N2a cells because of the disruption of tight junction proteins, claudin-5 and ZO-1, in bEnd.3 cells. The proteomic profiling of N2a cells after AgNP exposure identified 298 differentially expressed proteins related to fatty acid metabolism. Particularly, AgNP-induced palmitic acid production was observed in N2a cells, which might promote Aß generation. Moreover, AgNP exposure increased the protein expression of amyloid precursor protein (APP) and Aß generation-related secretases, PSEN1, PSEN2, and ß-site APP cleaving enzyme for APP cleavage in ALT and N2a cells, stimulated Aß40 and Aß42 secretion in the culture medium, and attenuated the gene expression of Aß clearance-related receptors, P-gp and LRP-1, in bEnd.3 cells. Increased Aß might further aggregate on the neuronal cell surface to enhance the secretion of inflammatory cytokines, MCP-1 and IL-6, thus inducing apoptosis in N2a cells. This study suggested that AgNP exposure might cause Aß deposition and inflammation for subsequent neuronal cell apoptosis to potentially induce AD progression.

Acute lung injury (ALI) occurs frequently in patients with severe traumatic brain injury (TBI) and is associated with a poor clinical outcome. Aquaporins (AQPs), particularly AQP1 and AQP4, maintain water balances between the epithelial and microvascular domains of the lung. Since pulmonary edema (PE) usually occurs in the TBI-induced ALI patients, we investigated the effects of a thaliporphine derivative, TM-1, on the expression of AQPs and histological outcomes in the lung following TBI in rats. TM-1 administered (10 mg/kg, intraperitoneal injection) at 3 or 4 h after TBI significantly reduced the elevated mRNA expression and protein levels of AQP1 and AQP4 and diminished the wet/dry weight ratio, which reflects PE, in the lung at 8 and 24 h after TBI. Postinjury TM-1 administration also improved histopathological changes at 8 and 24 h after TBI. PE was accompanied with tissue pathological changes because a positive correlation between the lung injury score and the wet/dry weight ratio in the same animal was observed. Postinjury administration of TM-1 improved ALI and reduced PE at 8 and 24 h following TBI. The pulmonary-protective effect of TM-1 may be attributed to, at least in part, downregulation of AQP1 and AQP4 expression after TBI.
