RESUMEN

Integrative experiment design assumes that we can effectively design a space of factors that cause contextual variation. However, this is impossible to do so in a sufficiently objective way, resulting inevitably in observations laden with surrogate models. Consequently, integrative experiment design may even deepen the problem of incommensurability. In comparison, one-at-a-time approaches make much more tentative assumptions about the factors excluded from experiment design, hence still seem better suited to deal with incommensurability.

RESUMEN

OBJECTIVE: To evaluate oncologic (such as disease-free and overall survival) and obstetric outcomes in patients diagnosed with malignant ovarian germ cell tumors (MOGCTs). METHODS: Patients diagnosed with MOGCTs between March 2007 and February 2022 were evaluated and patients who underwent fertility sparing surgery were included in this retrospective study. The obstetric and oncologic outcomes were evaluated by collecting data up until the patient's last follow-up visit from the hospital records and patient files. The study was approved by Baskent University Institutional Review Board (KA23/124). RESULTS: Seventy FSS patients were included in this study. The median age of the patients was 22.5 years (range: 11-37). The median follow-up time was 92.0 months (10-189). Immature teratoma was the most common histological subtype (32.9%). Bilateral involvement was detected in only one patient with immature teratoma (1.4%). The 5-year DFS rates of immature teratoma, dysgerminoma, yolk sac, and mixed germ cell histologic types were 91.1%, 94.1%, 82.4%, and 88.9%, respectively (P: 0.716). The 5-year OS rates of the same histologic types were 95.7%, 100%, 88.2%, and 88.9%, respectively (P = 0.487). All patients (100%) had a regular menstrual cycle after the completion of adjuvant treatment. The mean time between the last chemotherapy and menstruation was 4.38 months. To date, a total of 34 patients tried to conceive after the completion of disease treatment. A total of 23 (67.6%) patients conceived, resulting in 27 live births in 22 (100%) patients. CONCLUSION: Fertility preservation should be the first treatment option in MOGCTs in young patients due to the unilateral involvement of the disease and its chemosensitive nature.

RESUMEN

PURPOSE: We aimed to evaluate the effect of extending the culture of cleavage-stage embryos to the blastocyst stage in vitrified-warmed cycles on pregnancy outcomes. METHODS: This is a retrospectively designed pilot study of a single center. All patients who applied for freeze-all cycle procedures during in vitro fertilization treatment were included in the study. Patients were classified into three subgroups. The embryos obtained were frozen at the cleavage or blastocyst stage. After a warming process, the cleavage-stage embryos were divided into two subgroups: the first group of embryos was transferred (vitrification day 3-embryo transfer (ET) day 3 (D3T3)) on the warming day; for the second group, the embryo culture was extended to the blastocyst stage (vitrification day 3-ET day 5 (after the extension of the embryo culture to the blastocyst stage), (D3T5)). Frozen blastocyst-stage embryos were transferred after warming (vitrification day 5-ET day 5 (D5T5)). Hormone replacement treatment was the only endometrial preparation regimen given during the embryo transfer cycle. The main outcome of the study was live birth rates. The clinical pregnancy rate and positive pregnancy test rate were determined as the secondary outcomes of the study. RESULTS: The study included a total of 194 patients. The positive pregnancy test rates (PPR) and clinical pregnancy rates (CPR) of the D3T3, D3T5, and D5T5 groups were 14.0% and 59.2%; 43.8% and 9.3%; and 56.3% and 39.6%, respectively (p < 0.001 and p < 0.001). The live birth rates (LBR) of patients in the D3T3, D3T5, and D5T5 groups were 7.0%, 44.7%, and 27.1%, respectively (p < 0.001). In subgroup analysis of patients with a poor number of 2PN embryos (defined as having < = 4 2PN embryos), the D3T5 group had significantly higher PPR (10.7%, 60.6%, 42.4%; p < 0.001), CPR (7.1%, 57.6%, 39.4%; p < 0.001), and LBR (3.6%, 39.4%, 21.2%; p: 0.001). CONCLUSION: Extending the culture after warming to the blastocyst stage may be a better alternative than a cleavage-stage embryo transfer.

RESUMEN

OBJECTIVE: This study aimed to assess the long-term oncologic and obstetric outcomes of women with epithelial ovarian cancer who underwent fertility-sparing surgery. METHODS: A total of 68 patients observed between March 2007 and July 2021 were included in this retrospective study. Unilateral salpingo-oophorectomy and uterine preservation with staging surgery were the main procedures for fertility-sparing surgery. Disease-free, overall survival, and obstetric outcomes were measured as primary outcomes. RESULTS: The median age of the patients was 30.5 years. The median follow-up time was 60.5 months. Disease recurrence occurred in 15 (22.1%) of the patients. Five-year disease-free survival and overall survival (OS) percentages were 75.6% and 83.3%, respectively, for all stages. The FIGO (International Federation of Gynecology & Obstetrics) stage was the only significant factor that affected OS (P = 0.001). Twenty-three patients tried to conceive, and 15 (65.2%) patients became pregnant. Twelve (80%) pregnancies reached term and resulted in 15 live births. Chemotherapy administration and surgical intervention (cystectomy or unilateral salpingo-oophorectomy) showed no difference in pregnancy results (P = 0.806 and P = 0.066, respectively). CONCLUSION: Fertility preservation is safe for invasive epithelial ovarian cancer at early stages for women in the reproductive era. Disease recurrence and OS results are similar to standard treatment at early stages with decent obstetric outcomes.

RESUMEN

The scientific-reform movement, frequently referred to as open science, has the potential to substantially reshape the nature of the scientific activity. For this reason, its sociopolitical antecedents and consequences deserve serious scholarly attention. In a recently formed literature that professes to meet this need, it has been widely argued that the movement is neoliberal. However, for two reasons it is hard to justify this widescale attribution: First, the critics mistakenly represent the movement as a monolithic structure, and second, the critics' arguments associating the movement with neoliberalism because of the movement's (a) preferential focus on methodological issues, (b) underlying philosophy of science, and (c) allegedly promarket ideological proclivities reflected in the methodology and science-policy proposals do not hold under closer scrutiny. These shortcomings show a lack of sufficient engagement with the reform literature. What is needed is more nuanced accounts of the sociopolitical underpinnings of scientific reform. To address this need, we propose a model for the analysis of reform proposals, which represents scientific methodology, axiology, science policy, and ideology as interconnected but relatively distinct domains, and thus allows for recognizing the divergent tendencies in the movement and the uniqueness of particular proposals.

RESUMEN

BACKGROUND: Altered mental status occurs in one in four older adults, and the risk increases with age. Numerous scoring systems have been improved to predict mortality, but data are limited for these scoring systems to interpret older adult patients. AIM: We aimed to compare qSOFA and National Early Warning Score-2 (NEWS2) scores in predicting the prognosis of older adults with altered mental status. METHOD: We included 500 older adults with altered mental status. We noted the qSOFA and NEWS2 scores of the patients. We compared the qSOFA and NEWS2 scores for the prediction of 30-day mortality, 48-h mortality, hospitalization clinic, outcome, and hospitalization length. RESULTS: The mean NEWS2 score was 6.4, and the mean qSOFA score was 1.3. For 30-day mortality, the sensitivity and specificity of the NEWS2 score ≥ 5 were 68.29% and 69.6%, respectively, and those of qSOFA score > 1 were 47.14% and 78.75%, respectively. AUC values for 30-day mortality prediction were 0,725 (CI: 0.683-0.763) and 0.631 (CI: 0.587-0.673). For intensive care unit hospitalization prediction, the sensitivity and specificity of the NEWS2 score ≥ 5 were 52.73% and 77.67%, respectively, and those of qSOFA score > 1 were 35.32% and 81.55%, respectively. In patients with a NEWS2 score > 10 points, the predicted 48-h mortality had a specificity of 80.6%, which was higher than the qSOFA score. CONCLUSION: NEWS2 score can be used to predict 48-h mortality, 30-day mortality, and intensive care unit hospitalization compared with qSOFA in older adults with altered mental status.

RESUMEN

We investigate varieties of dissatisfaction by examining how the similar, yet distinct emotions of regret, disappointment, and anger are related to electoral behavior. In a 2-wave longitudinal study conducted around the UK General Election of 2017 (N1 = 817, N2 = 768), we measured these emotions in response to 3 levels of electoral decision-making (individual party preference, individual electoral participation, and election results) and tested the relationship between these emotions and electoral behaviors. We find that party switching in 2017 is associated with regret about the party preference in 2015 and the regret about those election results, but not with other emotions. Similarly, we also find that the regret about party preference in 2017 is associated with future party switching intentions. Disappointment with the decision to vote in the 2015 General Election is negatively associated with voting in 2017; and the same is true for the anger about participants' party choice. These results suggest that distinct dissatisfaction-related emotions might have distinct consequences for electoral behavior. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

Falsificationist and confirmationist approaches provide two well-established ways of evaluating generalizability. Yarkoni rejects both and invents a third approach we call neo-operationalism. His proposal cannot work for the hypothetical concepts psychologists use, because the universe of operationalizations is impossible to define, and hypothetical concepts cannot be reduced to their operationalizations. We conclude that he is wrong in his generalizability-crisis diagnosis.

RESUMEN

To assess the clinicopathological features, prognostic factors, and survival rates associated with uterine leiomyosarcoma (uLMS). Databases from 15 participating gynecological oncology centers in Turkey were searched retrospectively for women who had been treated for stage I-IV uLMS between 1996 and 2018. Of 302 consecutive women with uLMS, there were 234 patients with Federation of Gynecology and Obstetrics (FIGO) stage I disease and 68 with FIGO stage II-IV disease. All patients underwent total hysterectomy. Lymphadenectomy was performed in 161 (54.5%) cases. A total of 195 patients received adjuvant treatment. The 5-year disease-free survival (DFS) and overall survival (OS) rates were 42% and 54%, respectively. Presence of lymphovascular space invasion (LVSI), higher degree of nuclear atypia, and absence of lymphadenectomy were negatively correlated with DFS, while LVSI, mitotic count, higher degree of nuclear atypia, FIGO stage II-IV disease, and suboptimal surgery significantly decreased OS. LVSI and higher degree of nuclear atypia appear to be prognostic indicators for uLMS. Lymphadenectomy seems to have a significant effect on DFS but not on OS.

RESUMEN

OBJECTIVE: Prognostic factors associated with high-grade endometrial stromal sarcoma (HGESS) and undifferentiated uterine sarcoma (UUS) have not been distinctly determined due to the repetitive changes in the World Health Organization (WHO) classification. We aimed to compare clinicopathologic features and outcomes of patients with HGESS with those of patients with UUS. METHODS: A multi-institutional, retrospective, cohort study was conducted including 71 patients, who underwent surgery at 13 centers from 2008 to 2017. An experienced gynecopathologist from each institution re-evaluated the slides of their own cases according to the WHO2014 classification. Factors associated with refractory/progressive disease, recurrence or death were examined using logistic regression analyses. Kaplan-Meier method and log-rank test were used for survival comparisons. RESULTS: The median disease-free survival (DFS) for HGESS and UUS was 12 months and 6 months, respectively. While the median overall survival was not reached in HGESS group, it was 22 months in the UUS group. Kaplan-Meier analyses revealed that patients with UUS had a significantly poorer DFS than those with HGESS (p = 0.016), although OS did not differ between the groups (p = 0.135). Lymphovascular-space involvement (LVSI) was the sole significant factor associated with progression, recurrence or death for HGESS (Hazard ratio: 9.353, 95% confidence interval: 2.539-34.457, p = 0.001), whereas no significant independent factor was found for UUS. CONCLUSIONS: UUS has a more aggressive behavior than HGESS. While no significant predictor of prognosis was found for UUS, LVSI is the sole independent prognostic factor for HGESS, with patients 9.3 times more likely to experience refractory/progressive disease, recurrence or death.

RESUMEN

Objective: The primary aim of this study was to evaluate the factors affecting parametrial involvement in cervical cancer patients with tumor size ≤4 cm and selection of the low-risk patient group based on long-term oncologic outcomes. Material and Methods: Cervical cancer patients operated in the gynecologic oncology division between 2007 and 2013 were retrospectively evaluated. One-hundred and sixty-eight patients with tumor size ≤4 cm were identified. Of these, 159 (86.8%) underwent radical hysterectomy plus pelvic-para-aortic lymphadenectomy and nine (13.2%) underwent fertility-sparing surgery [radical trachelectomy (n=7); large conization (n=2)]. Factors affecting parametrial invasion, including lymphovascular space invasion (LVSI), deep stromal invasion (DSI), lymph node metastases, and tumor size, were evaluated. Statistical analyses were performed using SPSS 23.0 (IBM Corp., Armonk, NY, USA). Results: Median age was 49.5 years and median tumor size was 2.5 cm (0.45-4 cm). In both univariate and multivariate analyses, the risk of parametrial involvement was increased with LVSI with a hazard ratio (HR) of 3.45 [95% confidence interval (CI): 1.1-10.8] and DSI with a HR of 4.1 (95% CI: 1.18-14.8), while tumor size of ≤2 cm was only significant in univariate analyses. Furthermore, 26 early-stage patients were identified with low-risk factors and they had no parametrial involvement, lymph node metastases, recurrence, or death from disease over 77 months. Conclusion: Parametrial involvement in low-risk cervical cancer is very rare and less radical procedures may be safe in these patients.

RESUMEN

OBJECTIVE: To investigate factors associated with refractory disease, recurrence, or death as well as disease-free survival (DFS) and overall survival (OS) in low-grade endometrial sarcoma (LGESS). METHODS: A multi-institutional, retrospective study was conducted in a total of 124 patients, who received a curative-intent surgery. The exclusion criteria were as follows: i) history of any other invasive disease; ii) neoadjuvant therapy; iii) fertility sparing surgery; iv) a different diagnosis after review of the slides. RESULTS: All patients underwent hysterectomy, 96% had bilateral salpingo-oophorectomy, and 65% had lymphadenectomy. Twelve (14.8%) of 81 patients undergoing lymphadenectomy had lymph node (LN) metastasis. Of those, 8 (9.8%) had pelvic LN metastasis whereas 4 (5.6%) had isolated paraaortic LN metastasis. Six of 8 (75%) patients with positive pelvic LNs had concurrent paraaortic LN metastasis. Among 124 patients, 3 patients (2.4%) had refractory disease following primary therapy. During a median follow-up of 45.5 months, 27 (22.3%) of 121 patients who achieved complete remission after primary therapy developed recurrence, and 10 patients (8.1%) died of disease. The 3-year DFS and OS were 76.9% and 93.8%, respectively. Stage was the sole independent prognostic factor in the whole cohort. When analyzing factors within subgroups of stage I and stage ≥II, there was no significant prognostic factor for stage I; however, lymphadenectomy and adjuvant chemotherapy were significantly associated with disease outcomes for stage ≥II. While lymphadenectomy was related with improved DFS, chemotherapy was associated with poor DFS and OS. CONCLUSION: The risk of LN metastasis at pelvic as well as paraaortic lymphatic basins is not negligible to omit lymphadenectomy in stage ≥II LGESS. Moreover, lymphadenectomy provides significant DFS advantage in patients with extrauterine disease.

RESUMEN

OBJECTIVE: We aimed to investigate the effects of high-dose rocuronium administration on intra-abdominal pressure (IAP) and surgical conditions during anaesthesia induction and laparoscopic cholecystectomy anaesthesia induction, respectively. Further, we aimed to determine postoperative nausea and vomiting (PONV) and pain scores following the laparoscopic cholecystectomy. METHODS: Patients with American Society of Anesthesiologists (ASA) score of I-III, aged 18 to 75 years and who were scheduled for surgery under general anaesthesia were included in the study. Patients were randomised and a high-dose of 1.2 mg kg-1 rocuronium was given to Group A and 0.6 mg kg-1 rocuronium to Group B. The intraoperative train of four (TOF) ratio and post-tetanic count (PTC) were measured. Surgery was initiated with a low IAP of 7 mmHg. The surgeon evaluated surgical conditions with a 4-step surgical field scale and increased the IAP when necessary. PONV at 4, 12 and 24 hours and postoperative pain at 2 and 24 hours and 3 days were evaluated. RESULTS: There were no significant differences in the demographic and haemodynamic parameters between the groups. In high-dose rocuronium Group A, IAP values were significantly lower in the first 20 minutes compared to Group B. The duration of operations was significantly shorter in Group A (29.00±7.39 minute vs. 34.63±12.00 minute, p=0.044). PONV in the first 12 hours was significantly lower in Group A (p<0.05). CONCLUSION: High-dose rocuronium-induced deep neuromuscular block helped perform laparoscopic cholecystectomy operations with lower values of IAP compared to a normal dose rocuronium. It also shortened duration of operation and reduced PONV and pain.

RESUMEN

OBJECTIVE: The purpose of this study was to define the pregnancy and oncologic outcomes after fertility-sparing treatment of atypical hyperplasia (AH)/endometrial intraepithelial neoplasia (EIN) and early-stage endometrioid endometrial cancer (EEC). MATERIALS AND METHODS: The retrospective cohort study included patients who had applied to Baskent University's Ankara Hospital between January 2007 and October 2018 with either AH/EIN (n: 27; Group A) or EEC (n: 30; Group B), and who had the desire to preserve their fertility. The medical records of all patients included in the study were reviewed retrospectively from the hospital records. RESULTS: There were 2 (7.4%) and 5 (16.7%) recurrences, whereby one patient from Group A and two patients from Group B underwent staging surgery. In Group A, 8 patients attempted pregnancy after their treatment and 4 of them (50%) became pregnant, while 3 of them (37.5%) had a live birth. In Group B, there were 17 patients who wanted to become pregnant following treatment of the disease; 8 of them (47%) became pregnant after treatment, 5 of them (16.6%) had a live birth, 1 experienced intrauterine exitus (at 21st gestational week, 350 g), and 2 currently have ongoing pregnancies. CONCLUSION: Hysteroscopic resection of visible lesions and full endometrial curettage prior to hormonal therapy as a fertility-preserving approach for women of reproductive age with endometrial malignancies can achieve promising oncologic and obstetric responses.

RESUMEN

OBJECTIVE: Epithelial ovarian cancer (EOC) requires an aggressive surgical approach. The important part of literature on ovarian cancer surgery emphasize residual tumor and survival analyses. Morbidity issue keeps in background. Therefore, we aimed to report on morbidity of cytoreductive surgery for EOC in this study. METHODS: EOC patients who underwent primary debulking were evaluated. Intraoperative and postoperative complications that occurred within 30 days after the surgery and factors that affect morbidity were considered. RESULTS: The study involved 359 patients. Forty-six intraoperative complications occurred in 42 (11.6%) patients. Advanced stage and cancer antigen level of 125 were independently and significantly associated with operative complications (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.01-2,73; P=0.044, and HR, 1.47; 95% CI, 1.05-2.06; P=0.025, respectively). The need for intensive care unit admission was significantly higher in patients with intraoperative complications (28.6% vs. 8.8%, P=0.001). Intraoperative and postoperative complication rates were significantly higher in extended surgery than in standard surgery (18.9%vs. 8.5%, P=0.005 and 38.7% vs. 10.9%, P<0.001, respectively). Intraoperative and postoperative transfusion need, hospital stay duration, and chemotherapy start day were also significantly higher in extended surgery than in standard surgery. Hundred postoperative complications occurred in 70 patients. Age, extended surgery, presence of ascites, and presence of operative complications were independently and significantly associated with postoperative complications. CONCLUSION: Morbidity of extensive surgical approach should be kept in mind in ovarian cancer surgery aimed at leaving no residual tumor. Patient-based management with an appropriate preoperative evaluation may avoid morbidity of extended/extensive surgical approaches.

RESUMEN

The aim of this study is to present our clinical experience about fertility-sparing procedures in early stage cervical cancer and its obstetrical and oncological outcomes. Between the years 2006 and 2016, a total of 22 early stage cervical cancer patients who underwent a fertility-sparing radical abdominal trachelectomy in our clinic were retrospectively analysed. The median age was 33 (range: 28-39) years. The median follow-up was 47 (range: 22-125) months. Five patients (22.7%) had Stage IA1, three patients had (13.6%) Stage IA2, and 14 patients (63.6%) had Stage IB1 disease. Only one patient had a recurrence. A pregnancy was obtained in five patients (22.7%) and one of them (20%) had a live birth. A pregnancy was obtained spontaneously in two patients (40%), whereas assisted reproductive techniques were used in three of the patients (60%). A miscarriage occurred in two patients (40%), and one of them was within the first trimester and the other was within the second trimester. Impact statement What is already known on the subject? Currently, the first-line treatment of early stage cervical cancer is surgery. However, a fertility-sparing trachelectomy is the most widely adopted approach in the reproductive aged patients who have a desire to be pregnant later. What does this study add? In the literature, there is a growing number of studies on this subject. However, it would take time to obtain adequate knowledge. We believe that our study would contribute to the existing data. What are the implication of these findings for clinical practice? This study is important as it indicates that a multidisciplinary approach is required to preserve fertility among gynaecologic oncologists and the outcomes would be reflected into the clinical practice. In addition, we believe that our study would pave the way for further studies regarding this subject among oncologists.

RESUMEN

The enzymatic hydrolysis of hardwood and softwood harvest residues treated by SO2-ethanol-water (SEW) fractionation was studied. The target was to convert these fibers with high yield into glucose monomers which could be further converted into biofuel by a subsequent fermentation stage. Hardwood biomass residues were efficiently digested at low enzyme dosage (5 FPU/g cellulose) whereas the softwood residues required notably higher enzyme dosage (20 FPU) for sufficient conversion. However, cellulase dosage of softwood could be reduced mannanase supplementation. Especially the high lignin content of softwood biomass pulps impairs the digestibility and thereby, improved delignification could notably enhance the hydrolysis yields. It was shown that inferior delignification of SW biomass is due to persistent polyphenolic acids present in coniferous bark, whereas no evidence of the negative effect of inorganics and acetone extractives was observed.
