RESUMEN

AIMS AND OBJECTIVES: To investigate the psychological distress, sexual satisfaction, and quality of life of gynaecological cancer survivors and their spouses during cancer survivorship. BACKGROUND: The survival rate of patients with cancer is increasing owing to advances in medical treatment technology. Spouses are the closest companions of gynaecological cancer survivors. Patients with gynaecological cancer and their spouses face different situations and challenges after experiencing cancer invasion. DESIGN: Questionnaire-based cross-sectional study. METHODS: Convenience sampling was employed, and 180 participants, including patients with gynaecological cancer and their spouses, were enrolled. A structured questionnaire was used to investigate the psychological distress, sexual satisfaction, and quality of life of gynaecological cancer survivors and their spouses during acute, extended, and permanent survivorship. The STROBE checklist guided the study preparation. RESULTS: For gynaecological cancer survivors and their spouses, (1) severe psychological distress was present during acute survivorship, with anxiety extending until permanent survivorship; (2) no significant differences were observed in pre- and post-treatment sexual satisfaction, although pre-treatment sexual satisfaction was higher than post-treatment sexual satisfaction in all three cancer survivorship stages and (3) quality of life decreased during acute survivorship and gradually improved with time. CONCLUSIONS: Psychological distress, sexual satisfaction and quality of life of gynaecological cancer survivors and their spouses worsened during acute survivorship and improved over time until permanent survivorship. RELEVANCE TO CLINICAL PRACTICE: Gynaecological cancer survivors and their spouses experience anxiety and depression from diagnosis confirmation until permanent survivorship (>5 years survival). Therefore, clinical nurses' sensitivity to emotional distress in cancer survivors and their spouses can be improved and a consistent and routine evaluation method has been established for the early detection of such emotional distress. The results of this study can provide a reference for clinical healthcare professionals and contribute to a better quality of care.

RESUMEN

Objective: The primary aim of this study is to investigate the relationship between vitamin D serum level and the incidence of postpartum hemorrhage (PPH). The secondary objective is to determine the relative risk of low vitamin D associated with PPH. Methods: This was a retrospective observational study. A total of 600 women who had delivered their babies in a single tertiary teaching hospital were enrolled. Serum blood test for 25(OH)D was performed at 35 + 0 to 36 + 6 weeks of pregnancy to measure vitamin D. A 25(OH)D level < 20 ng/mL was defined as vitamin D deficient, and a level 21-29 ng/mL as insufficient. Results: Vitamin D levels were deficient in 145 (24.1%) and insufficient in 254 (42.3%) of the women tested. Women with deficient and insufficient vitamin D levels were significantly younger than those with sufficient vitamin D levels (p < 0.001). The overall rates of PPH in the deficient and insufficient groups were 6.9% (10/145) and 6.7% (17/254), respectively, and were significantly higher than the rate of the normal vitamin D group (1.5%, p = 0.009). Women with sufficient vitamin D levels had significantly higher hemoglobin levels than those with low vitamin D levels. Higher vitamin D levels were associated with a significantly low risk of PPH (AOR: 0.93, CI: 0.89-0.98, p = 0.006). Conclusion: Our results suggest that a low vitamin D level is a risk factor for PPH. Low vitamin D also related to high risk of low hemoglobin before delivery. Thus, antepartum care should include vitamin D supplements for all women if possible.

RESUMEN

This large-scale study aimed to determine the long-term influences of potential prognostic predictors and progression-free interval (PFI) criteria for grading platinum-sensitivity in ovarian clear cell carcinoma (OCCC). We retrospectively reviewed the medical records of OCCC patients presenting at nine tertiary centres (1995−2015), and evaluated patient characteristics, therapeutic factors, clinical outcomes, and hazard ratios for disease progression and death. We enrolled 536 patients (median follow-up, 36.6 months) and developed newly defined distributions of PFIs (seven and 14 months) for grading platinum sensitivity. In the multivariate model, preoperative CA125 levels and chemo-response independently predicted early-stage progression-free survival (PFS) risk. Post-progression cytoreduction correlated with reduced mortality risk. No unfavourable outcomes were observed with respect to coexisting endometriosis, fertility-sparing strategies, or platinum-based regimens. A PFI of <7 months, the strongest predictor of both post-progression mortality and second relapse risks, correlated with chemo-resistance, advanced tumour stage, and shortened post-progression survival. Chemotherapy regimens commonly used in front-line or relapse settings were limited in improving prognoses, especially in the advanced-stage cohort. Clinical trials of novel targeted agents and/or innovative biomarkers for chemoresistance should be comprehensively investigated and offered early to advanced-stage patients or those with OCCC progression occurring within seven months after receiving chemotherapy.

RESUMEN

OBJECTIVE: PPH is usually unpredictable; and such fast, urgent and sudden massive life-threating hemorrhage. This study is to assess the efficacy of transarterial embolization (TAE) in treating severe PPH in a single institution over a period of 20 years. MATERIALS AND METHODS: From January 2000 to October 2019, all women with acute PPH more than 1500 cc and/or DIC were enrolled in this retrospective study. These women were divided into two groups according to whether they have received TAE as the second-line treatment. Group 1 (n = 27) included women without receiving TAE from January 1, 2000 to October 31, 2009, and group 2 (n = 30) included those who receiving TAE from November 1, 2009 to October 31, 2019. RESULTS: The overall success rate of TAE in control the PPH and preserved the uterus is 80%. The hemoglobin 12 h after PPH in group 2 is significantly lower than in group 1 (7.64 ± 1.6 vs. 8.58 ± 1.9, respectively. P = 0.05). Total unit of packed red blood cell (pRBC) transfusion is significantly higher in the group 2 than group 1 (9.8 ± 5.7 vs. 6.8 ± 3.9; p = 0.03). The rate of hysterectomy is significantly higher in group 1 than group 2 (46.7 vs. 20%; p < 0.001). CONCLUSION: In conclusion, TAE is safe and effective in control bleeding in PPH with a high success rate to preserve uterus and prevent DIC. TAE should be routinely used as a secondary line of treatment during PPH in all hospitals.

RESUMEN

Objective: Three vaccines are available to Taiwanese young girls for cervical cancer (CC) prevention. Here we evaluate the cost-effectiveness of the two-dose (2D) AS04-adjuvanted HPV-16/18 vaccine (2D-AS04-HPV- 16/18v)+screening compared with a screening programme alone, with 2D human papillomavirus 6/11/16/18 vaccine (2D-4vHPVv)+screening, and with 2D/three-dose (3D) human papillomavirus 6/11/16/18/31/33/45/52/58 vaccine (9vHPVv)+screening, for Taiwan universal mass vaccination. Methods: A static Markov cohort model simulated the natural history of human papillomavirus (HPV) infection and CC screening for a 12-year-old cohort of Taiwanese girls (N=120,000). The model ran in 1-year cycles over the cohort's lifetime. Vaccine efficacy irrespective of HPV type was considered in the analysis for each vaccine. Input data were obtained from published literature, local databases, government reports and websites, and expert opinion. The analysis incorporated direct medical costs only, with an annual discount rate of 3.0%. The threshold was determined as 1 Gross Domestic Product per capita (New Taiwan dollar [NT$] 727,818; year 2016). Results: The 2D-AS04-HPV-16/18v+screening yielded 0.0365 quality-adjusted life year (QALY) gained at an additional cost of NT$ 5,770 per person compared with the screening programme alone. This resulted in an incremental cost-effectiveness ratio well below the threshold. Compared with 2D-4vHPVv+screening and 2D/3D-9vHPVv+screening, discounted results demonstrated additional QALYs gained at lower cost for 2D-AS04-HPV- 16/18v+screening, making it dominant over both 2D-4vHPVv+screening and 2D/3D-9vHPVv+screening. Conclusions: Vaccinating Taiwanese girls with 2D-AS04-HPV-16/18v in addition to screening to prevent CC is cost-effective compared with using a screening programme alone and the dominant option compared with 2D-4vHPVv+screening and 2D/3D-9vHPVv+screening.

RESUMEN

OBJECTIVE: Acquired uterine arteriovenous malformation (UAVM) is a rare, life-threatening disease. Angiography with uterine arterial embolization (UAE) is the diagnostic tool and a choice of fertility-sparing treatment. Here, we present a series of five successful pregnancies after embolization of UAVM. CASE REPORTS: Three reproductive aged women were treated for UAVM, resulting in five successful pregnancies. Their past history suggested that three cases had had previous uterine procedures, including second trimester abortion and elective dilatation and curettage. Intermittent heavy vaginal bleeding was the primary symptom of UAVM. One patient with anemia had two ineffective embolizations and achieved a singleton pregnancy after the third embolization. However, intrauterine fetal demise with severe fetal growth retardation was noted on the 28th gestation week. The other two women had temporary ovulation disorder after UAE. After Clomiphene Citrate (CC) treatment, successful pregnancies were achieved and carried to term uneventfully. CONCLUSION: UAE is an acceptable method for preserving fertility and treatment in women with symptomatic UAVMs.

RESUMEN

BACKGROUND: The Papanicolaou (Pap) test is one screening strategy used to prevent cervical cancer in developed countries. The p16/Ki-67 immunocytochemistry is a triage test performed on Pap smears in women with atypical squamous cells of undetermined significance (ASCUS) or low grade squamous intraepithelial lesion. OBJECTIVE: Our objective was to review studies investigating the diagnostic performance of p16/Ki-67 dual stain for triage of women with abnormal Pap tests. DESIGN: We conducted a systematic review and meta-analysis of diagnostic test accuracy studies. SETTINGS: We followed the protocol of systematic review of diagnostic accuracy studies. PATIENTS AND METHODS: We searched PubMed, The Cochrane Library, BioMed Central, and ClinicalTrials.gov for relevant studies. We included research that assessed the accuracy of p16/Ki-67 dual stain and high risk human papillomavirus testing for triage of abnormal Pap smears. Review articles and studies that provided insufficient data to construct 2.2 tables were excluded. Data synthesis was conducted using a random-effects model. MAIN OUTCOME MEASURES: Sensitivity and specificity. RESULTS: In seven studies encompassing 2628 patients, the pooled sensitivity and specificity of p16/Ki-67 for triage of abnormal Pap smear results were 0.91 (95% CI, 0.89 to 0.93) and 0.64 (95% CI, 0.62 to 0.66), respectively. No study used a case-control design. A subgroup analysis involving liquid-based cytology showed a sensitivity of 0.91 (95%CI, 0.89 to 0.93) and specificity of 0.64 (95%CI, 0.61 to 0.66). CONCLUSIONS: Our meta-analysis of p16/Ki-67 dual stain studies showed that the test achieved high sensitivity and moderate specificity for p16/Ki-67 immunocytochemistry for high-grade squamous intraepi.thelial lesion and cervical cancer. We suggest that p16/Ki-67 dual stain might be a reliable ancillary method identifying high-grade squamous intraepithelial lesions in women with abnormal Pap tests. LIMITATIONS: No study in the meta-analysis examined the accuracy of the p16/Ki-67 dual stain for inter.pretation of glandular neoplasms.

RESUMEN

OBJECTIVE: The standard dose of depot gonadotropin releasing hormone agonist (GnRHa) may be too much to prevent premature luteinizing hormone (LH) surge in controlled ovarian stimulation (COS). The purpose of this study was to find out the minimal effective dose of Leuplin depot to prevent premature LH surge in patients undergoing intrauterine insemination (IUI). MATERIALS AND METHODS: From January 2006 to December 2007, unexplained infertile patients who were going to undergo IUI were recruited into the study. They were assigned sequentially to one of the following treatment groups. The first 50 patients received the 1/3-dose of Leuplin depot in the midluteal phase of the cycle preceding COS. If no premature LH surge occurred in the 50 patients, the study was continued with 1/4-dose of Leuplin depot in the subsequent 50 patients. Similarly, if no premature LH surge occurred with 1/4 dose, the study was continued with 1/5-dose of Leuplin depot in the following 50 patients. Ovarian stimulation was started with human menopausal gonadotropin (hMG) at 112.5 IU/d after downregulation, then IUI was performed 36 hours after human chorionic gonadotropin (hCG) injection. RESULTS: Premature LH surge was effectively prevented with 1/3-dose and 1/4-dose of Leuplin depot. Premature LH surge occurred in three of the 50 patients (6%) in the 1/5-dose group. The patients in the 1/4-dose group received a significantly lower amount of hMG and fewer days of COS, compared with the 1/3-dose group. CONCLUSION: The 1/4 dose of Leuplin depot is the minimal effective dose to prevent premature LH surge. Further trial is worthwhile to compare the reducing dose Leuplin depot and daily low-dose leuprolide in in vitro fertilization (IVF) programs.

RESUMEN

OBJECTIVE: To assess bacterial colonization following balloon uterine stent placement in the uterus for 30 days. DESIGN: Prospective randomized controlled study. SETTING: Tertiary medical center. PATIENT(S): Sixty-eight women scheduled for hysteroscopy. INTERVENTION(S): Women who were undergoing hysteroscopic surgery were randomly assigned to receive a balloon uterine stent or not. Before starting surgery, the uterine cavity was swabbed for bacterial culture. The device was placed in the uterus after surgery in the stent group. After 30 days, the stent was removed and sent for culture and the uterine cavity also swabbed and cultured. The uterine cavities of the control patients were swabbed before and 30 days after surgery. MAIN OUTCOME MEASURE(S): The primary outcome was the incidence of bacterial colonization of the uterus. Secondary outcomes were pain intensity and species of colonizing bacteria. RESULT(S): Excluding eight women, 30 women in each group were included in this analysis. In the stent group, three women (10.0%) demonstrated bacterial colonization before surgery compared with nine women (30.0%) after 30 days. In the control group, four (13.3%) and ten (33.3%) women had microorganisms detected in the uterus before and after 30 days after surgery, respectively. In neither group did the percentage of women with uterine microorganisms increase significantly after 30 days. The percentages of women with uterine bacterial colonization before and 30 days after surgery were similar between both groups. CONCLUSION(S): Balloon uterine stents may be placed after surgery for up to 30 days without increasing bacterial colonization. CLINICAL TRIAL REGISTRATION NUMBER: ClinicalTrials.gov (www.clinicaltrials.gov) NCT01167296.

RESUMEN

PURPOSE: The outcomes of in-vitro maturation (IVM) are inferior compared to those of IVF. The purpose of the study was to compare the implantation rates of IVM- and in-vivo maturation (IVO)- derived embryos, and to evaluate their effects on uterine receptivity. METHODS: The IVM- and IVO- oocytes were obtained from female mice, fertilized and transferred to separate oviducts of the same pseudo-pregnant mice. After 5 days, the implanted blastocysts were dissected out of the uterine horns, and the uterine horns were analyzed for the expression of mRNAs encoding leukemia inhibitory factor, heparin-binding epidermal growth factor, insulin-like growth factor binding protein-4, progesterone receptor, and Hoxa-10. RESULTS: The maturation rate of the IVM- oocytes was 81.2%. The fertilization rate of the IVM oocytes was lower than that of the IVO oocytes (50.5% vs. 78.0%, p = 0.038), as was their implantation rate (14.5% vs. 74.7%, p < 0.001). All 5 mRNAs examined were expressed at significantly lower levels in the uterine horns that received the IVM-derived embryos than in those that received the IVO-derived embryos. CONCLUSIONS: The IVM-derived embryos are less competent in inducing expression of implantation-related mRNAs in the uterine horn.

RESUMEN

The aim of this study was to assess the effectiveness and safety profile of a new technique for ultrasonographically assisted percutaneous carpal tunnel release. Experiments were performed on 40 hands in 20 cadavers. We first performed a detailed ultrasonographic examination and correlation study that included surgical dissection of the transverse carpal ligament, the related neurovascular structures and the bony landmarks of the radiocarpal, midcarpal and carpometacarpal joints of the right hand. We then used the measurements we made for percutaneous carpal tunnel release of the transverse carpal ligament using intra-operative ultrasonography for guidance and a hook knife on the left-hand side. The completeness of the release and the potential risks of injury to the flexor tendon and neurovascular bundles were examined. Using real-time intra-operative ultrasonographic monitoring to clearly delineate these targets, we were able to percutaneously release the transverse carpal ligament completely in 18 (90%) of the 20 hands and partially release it in 2 without injuring any neurovascular bundles. We then performed the procedure on 91 consecutive cases of carpal tunnel syndrome and found that the sensory disturbances disappeared in 100% patients 12 mo post-operatively; only 2 hands were graded as unsatisfactory. There were no intra- or post-operative complications. Based on the results from the cadaveric studies and our successful preliminary clinical outcomes, we conclude that this method is tolerable and that its clinical application can be encouraged.

RESUMEN

OBJECTIVE: The purpose of the study was to compare the Quinn's Advantage fertilization medium (Q1) and the tissue culture medium 199 (TCM199) for in vitro maturation (IVM) of oocytes and ammonium production during IVM. MATERIALS AND METHODS: The immature murine oocytes were randomly added into Q1 and TCM199. Ammonium concentrations were measured at the start and after 18 hours of IVM, and the mature oocytes were fertilized and cultured into blastocysts. The blastocysts were then stained for inner cell mass (ICM) and trophectoderm. RESULTS: The maturation rate was higher in Q1 than in TCM199 (85.7% vs. 76.6%, p = 0.024). The fertilization and blastocyst rates were slightly higher in Q1, but not significant. Differential staining of the blastocysts showed slightly higher ICM ratio in the blastocysts derived from Q1. Mean ammonium concentrations in Q1 and TCM199 at Time 0 were 184.9 and 339.2 µg/dL, respectively (p = 0.05), and after 18 hours of IVM were 268.7 and 443.6 µg/dL, respectively (p = 0.045). Addition of ammonium chloride into Q1 adversely affects IVM. CONCLUSION: Q1 is superior to TCM199 in terms of oocyte maturation, which may be due to lower ammonium concentration.

RESUMEN

STUDY OBJECTIVE: Cervical stenosis can be an impediment to embryo transfer (ET) and intrauterine insemination (IUI). We propose a technique of hysteroscopic cervical resection to overcome cervical stenosis. DESIGN: Prospective clinical study (Canadian Task Force classification III). SETTING: Private general hospital. PATIENTS: Forty-three infertile women in whom trial ET or IUI had failed with 3 available catheters. INTERVENTIONS: The procedure was performed with a hysteroscope under ultrasound guidance. Starting from the external os, the loop electrode gradually resected protrusions and cervical tissue until the hysteroscope could enter the uterine cavity. Repeat trial ET/IUI was performed 1 month later. The women who became pregnant underwent sonographic measurement of the cervical length and dilatation in the second and third trimesters. MEASUREMENTS AND MAIN RESULTS: Excluding 13 patients in whom the sound could pass through the cervical canal after anesthesia, 30 patients were included for analysis. The procedure failed in 1 patient (3.3%). The mean operation time was 18.0 (±7.4) minutes. Repeat trial ET/IUI was successful in all patients. There were 5 twin pregnancies and 9 singleton pregnancies after IUI or ET. From the 5 women with twin pregnancies; 2 underwent premature delivery at 34 weeks; and 3 underwent elective cesarean delivery at 35, 36, and 37 weeks, respectively. From the 9 women with singleton pregnancies, 1 underwent cesarean section at 36 weeks because of preeclampsia, and the other 8 delivered at term. CONCLUSION: Hysteroscopic cervical resection is a safe and effective treatment for cervical stenosis.

RESUMEN

PURPOSE: Embryo cryopreservation after triggering oocyte maturation with GnRH agonist (GnRHa) in GnRH antagonist protocols has been proposed to prevent ovarian hyperstimulation syndrome (OHSS). However, a small percentage of patients still developed severe OHSS. The purpose of the study was to investigate the efficacy of preventing OHSS in patients at very high risk when cabergoline was given in addition to elective cryopreservation after GnRHa triggering. METHODS: This is a retrospective observational study. The patients were stimulated with GnRH antagonist protocol. When serum E2 concentration was >6,000 pg/ml and there were more than 20 follicles ≥11 mm on the day of final oocyte maturation, GnRHa was used to trigger oocyte maturation. Cabergoline was given to augment the effect of preventing OHSS. The embryos were electively cryopreserved by vitrification and thawed in subsequent cycles. The primary outcome measure was the incidence of severe OHSS. The secondary outcome measure was the clinical pregnancy rate in the first frozen-thawed embryo transfer cycle. RESULTS: One hundred and ten patients underwent 110 stimulated cycles were included for analysis. No patients developed moderate/severe OHSS. Mean E2 concentration on the day of final oocyte maturation was 7,873 pg/ml, and an average of 22.7 oocytes was obtained from each patient. One hundred and ten thawing cycles were performed, resulting in 69 clinical pregnancies (62.7 %). CONCLUSIONS: Combining cabergoline and embryo cryopreservation after GnRHa triggering in GnRH antagonist protocol could prevent OHSS in patients at very high risk.

RESUMEN

Cabergoline, a dopamine receptor-2 agonist, is suggested to prevent ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation. The aim of this study was to evaluate the influence of different timing of cabergoline administration on clinical outcome among patients at risk of developing OHSS. Among infertile women undergoing IVF treatment at risk of developing OHSS, 206 were enrolled in this study. The subjects were randomly allocated into two groups, i.e. the study group (n=100) receiving cabergoline beginning on the day of human chorionic gonadotrophin (HCG) injection and the control group (n=100) receiving cabergoline starting on the day of oocyte retrieval. Oocyte metaphase-II rate, fertilization rate, clinical outcome and incidence of severe OHSS were compared between the two groups. There were no significant differences in oocyte metaphase-II rate (0.86 ± 0.16 versus 0.85 ± 0.15) or fertilization rate (0.79 ± 0.22 versus 0.76 ± 0.20) or in the incidence of OHSS between two groups. Similarly, there were no significant differences in implantation or clinical pregnancy rate between the two groups. Cabergoline can be administered as soon as HCG injection to prevent early OHSS, without adverse effects on oocyte maturation, fertilization rate and clinical outcome.

RESUMEN

PURPOSE: Cesarean scar pregnancy (CSP) is one of the rarest forms of ectopic pregnancy. A delay in treatment can lead to massive bleeding, uterine rupture, and life-threatening maternal morbidity. We present a conservative method for the management of CSP at a single tertiary centre over a 6-year period. METHODS: Eleven patients with unruptured CSPs who were treated by transvaginal aspiration of the gestational sac followed by a local methotrexate injection were evaluated. RESULTS: Gestational age at diagnosis ranged from 5 + 2 weeks to 7 + 4 weeks. Seven of the patients had undergone two prior Caesarean sections (63.6 %). The levels of ß-hCG at the time of diagnosis ranged from 1,290 to 81,586 mIu/ml. The mean time of the procedure was 8.2 ± 1.6 min. During follow up, 54.5 % of the patients may need an additional systemic MTX injection due to an elevation of ß-hCG. Estimated blood loss of the procedure was <50 ml and no blood transfusion is needed. This method has a shorter operative time, less blood loss and no hospitalization is needed for CSPs. All patients had their uterus successfully preserved without maternal morbidity or mortality. CONCLUSIONS: Transvaginal sono-guided sac aspiration concurrent with a local MTX injection is an effective management option for preserving the fertility of women with an unruptured CSP. However, additional systemic MTX injection may be needed if ß-hCG levels >20,000 mIU/ml at diagnosis.

RESUMEN

OBJECTIVE: Gastric type of adenocarcinoma (GAC) is a newly reported, morphologically distinct, mucinous subtype of cervical adenocarcinoma and is distinguished by aggressiveness and fatal outcomes. The association between human papillomavirus (HPV) and cervical carcinoma is well known; however, GAC is almost always HPV negative. MATERIALS AND METHODS: We report an unusual case of cervical GAC in a 41-year-old woman with a metastatic ovarian mass. The histological morphology of both tumors consisted of irregular glands lined by mucous cells with mild to moderate nuclear atypia and containing abundant cytoplasmic mucin. RESULTS: Immunohistochemical studies of the tumor cells revealed positive reactivity for CK7 and carcinoembryonic antigen but negative reactivity for p16 and HPV DNA usually expressed in cervical adenocarcinoma. Further staining for mucin with monoclonal antibody HIK1083 showed positive reactivity in both cervical and ovarian tumors. A gastric type of cervical carcinoma is considered. The patient is free of detectable disease at a 12-month follow-up. CONCLUSIONS: P16 staining and HPV DNA test result are usually positive in usual mucinous type of cervical adenocarcinoma, but they are negative in GAC. HIK1083 is becoming more commonly used for the diagnosis of GAC. Differentiation of GAC from usual mucinous type of cervical adenocarcinoma is important because GAC was related to a significant risk of recurrence and decreased 5-year disease-specific survival. We suggest applying HIK1083 in the diagnosis of cervical adenocarcinoma, especially in a small biopsy specimen.
