The purpose of this study was to explore the relationship between parental authority and social anxiety. The study attempted to answer the following question: Are there significant differences in social anxiety due to parental authority factors: (support, control, psychological control, emotion and accomplishment of missions)? Data was collected from 172 students of College of Education at Sultan Qaboos University. The Parental Authority Questionnaire (FAQ), and Social Anxiety Scale (SAS) were used to assess variables. To answer the study question, re- gression analysis was used. Findings indicated that there was significant relationship between parental authority and social anxiety in several domains. The findings also revealed that there were significant differences in social anxiety due to mother authority and student's gender.

This study examined the relationships among implicit self-theories, achievement goals, and academic delay of gratification. Do achievement goals mediate the relationship between implicit self-theories and academic delay of gratification? A sample of 195 Omani high school students rated themselves on three measures tapping these constructs. A path analysis showed that entity beliefs positively predicted performance-approach and performance-avoidance goals. Incremental beliefs positively predicted a mastery-approach goal. Incremental beliefs and entity beliefs positively and negatively, respectively, predicted academic delay of gratification. A mastery-approach positively predicted academic delay of gratification. Mastery-avoidance, performance-approach, and performance-avoidance negatively predicted academic delay of gratification. (Contains 4 tables and 1 figure.)

Scapegoating and Conspiracy Theories during COVID-19 Antisemitism has unfortunately persisted throughout history, and the COVID-19 pandemic has not been an exception to this troubling trend. The conditions created by the pandemic, such as fear, uncertainty, and anxiety, have fueled the emergence and spread of conspiracy theories targeting various groups, including Jewish communities. The COVID-19 pandemic has triggered a plethora of baseless beliefs and conspiracy theories about its causes, which have contributed to the rise of antisemitism during this time. Pandemics, including the COVID-19 pandemic, inherently create anxiety and uncertainty among populations. This change has affected many areas, both political and social. Conspiracy theories that base the cause of the emergence of COVID-19 on Jewish identity are an essential factor for this study. Tendencies toward antisemitism and scapegoating have supported these conspiracy theories. In this study, how antisemitism manifested itself in media and online discourse during COVID-19 and how Jewish identity is affected by the process.

Objective: Pressure ulcers (PU) are common in patients admitted to palliative care clinics (PCC). Pregressive nutritional deficiency, incontinence, and limitation of movement increase the risk of new PU formation. Purpose: To examine the risk of PU in patients hospitalized in PCC andthe rate of wounds on admission. Materials and Methods: We retrospectively analyzed patients hospitalized between 2017 and 2019 in a PCC integrated into a tertiary health institution. Patients with demographic and clinical data, data on the region, number, and stage of PU, and Norton and Braden pressure risk scores were enrolled. Patients with scores 11 on the Norton scale and 18 on the Braden scale were considered to be at higher risk for PU. Results: The final analysis included 566 patients [mean age: 68 years, male: 328 (58%)]. On admission, PU was recorded in 181 patients (32%) (sacrum: 80%). According to the Norton scale, 269 (47.5%) of all cases were under the risk of PU and 48.7% (n=131) of them already had PU. According to the Braden scale, 475 (83.9%) patients were at risk of PU, and 37.5% (n=178) of them already had PU. Among subjects with a low Norton score (n=297), 16% (n=50) already had PUs. Among subjects with PUs, the Norton score was not high 27.6%. Only 3.3% (n=3) of 91 patients whose Braden score was not low already had a PU. The sensitivity and specificity of the Norton score in the prediction of PU were 48.9% and 83.2%, respectively. The sensitivity and specificity of the Braden score in the prediction of PU were 66.9% and 99.0%, respectively. Conclusion: Physical PU examination on admission to PCC and during follow-up can identify a significant number of cases. The utility of Norton and Braden scores to estimate the occurrence of PUs may be limited in the palliative care setting or patients.

Aims:The evaluation of swallowing in the palliative care (PC) unit (PCU) is an important indicator of care. In this study, we investigated how an on-admission swallowing test in the PCU guides the course of the feeding route.Methods:This single-center, retrospective study included PC patients who underwent bedside swallowing evaluation. The main exclusion criteria were gastrointestinal failure requiring permanent parenteral nutrition, no swallowing test upon admission, and a length of stay shorter than four days. The primary endpoint was the proportion of patients with dysphagia who transitioned to oral feeding.Results:The study included 63 patients [age, median interquartile range: 80.0 (14) years (37 to 94 years); males: 54.0%]. Thirty-six (57.1%) of 63 admissions had dysphagia, whereas 27 (42.9%) patients had no dysphagia. The route of feeding was modified in 50.8% of the samples during their PCU stay. The proportion of patients who returned to oral feeding was 30.2% (n=19), whereas 6.3% (n=4) and 12.7% (n=8) of the sample underwent nasoenteral tube and percutaneous endoscopic gastrostomy (PEG) placement, respectively. Among the 32 patients who were on tube feeding on admission, 12 (37.5%) returned to oral feeding during their PCU stay. Seven (58.4%) of these subjects who regained oral feeding were on nasoenteral tube feeding and 5 (41.6%) were on PEG feeding on admission.Conclusions:This study showed a high rate of dysphagia on admission to the PCU. On the other hand, safe and adequate oral feeding could be re-initiated in almost one-third of patients with dysphagia on admission.

Orthosiphon stamineus is a popular folk herb used to treat diabetes and some other disorders. Previous studies have shown that O. stamineus extracts were able to balance blood glucose levels in diabetic rat animal models. However, the antidiabetic mechanism of O. stamineus is not fully known. This study was carried out to test the chemical composition, cytotoxicity, and antidiabetic activity of O. stamineus (aerial) methanol and water extracts. GC/MS phytochemical analysis of O. stamineus methanol and water extracts revealed 52 and 41 compounds, respectively. Ten active compounds are strong antidiabetic candidates. Oral treatment of diabetic mice with O. stamineus extracts for 3 weeks resulted significant reductions in blood glucose levels from 359 ± 7 mg/dL in diabetic non-treated mice to 164 ± 2 mg/dL and 174 ± 3 mg/dL in water- and methanol-based-extract-treated mice, respectively. The efficacy of O. stamineus extracts in augmenting glucose transporter-4 (GLUT4) translocation to the plasma membrane (PM) was tested in a rat muscle cell line stably expressing myc-tagged GLUT4 (L6-GLUT4myc) using enzyme-linked immunosorbent assay. The methanol extract was more efficient in enhancing GLUT4 translocation to the PM. It increased GLUT4 translocation at 250 µg/mL to 279 ± 15% and 351 ± 20% in the absence and presence of insulin, respectively. The same concentration of water extract enhanced GLUT4 translocation to 142 ± 2.5% and 165 ± 5% in the absence and presence of insulin, respectively. The methanol and water extracts were safe up to 250 µg/mL as measured with a Methylthiazol Tetrazolium (MTT) cytotoxic assay. The extracts exhibited antioxidant activity as measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. O. stamineus methanol extract reached the maximal inhibition of 77 ± 10% at 500 µg/mL, and O. stamineus water extract led to 59 ± 3% inhibition at the same concentration. These findings indicate that O. stamineus possesses antidiabetic activity in part by scavenging the oxidants and enhancing GLUT4 translocation to the PM in skeletal muscle.

The stem of Tinospora cordifolia has been traditionally used in traditional Indian systems of medicine for blood sugar control, without the knowledge of the underlying mechanism and chemical constitution responsible for the observed anti-diabetic effect. In the present study, Tinosporaside, a diterpenoid isolated from the stem of T. cordifolia, was investigated for its effects on glucose utilization in skeletal muscle cells, which was followed by determining the anti-hyperglycemic efficacy in our diabetic db/db mice model. We found that tinosporaside augmented glucose uptake by increasing the translocation of GLUT4 to the plasma membrane in L6 myotubes, upon prolonged exposure for 16 h. Moreover, tinosporaside treatment significantly increased the phosphorylation of protein kinase B/AKT (Ser-473) and 5′ AMP-activated protein kinase (AMPK, Thr-172). These effects were abolished in the presence of the wortmannin and compound C. Administration of tinosporaside to db/db mice improved glucose tolerance and peripheral insulin sensitivity associated with increased gene expression and phosphorylation of the markers of phosphoinositide 3-kinases (PI3Ks) and AMPK signaling in skeletal muscle tissue. The findings revealed that tinosporaside exerted its antidiabetic efficacy by enhancing the rate of glucose utilization in skeletal muscle, mediated by PI3K- and AMPK-dependent signaling mechanisms.

Since ancient times, Mandragora autumnalis has been used as a traditional medicinal plant for the treatment of numerous ailments. In light of this, the current study was designed to isolate and identify the chemical constituents of the flavonoids fraction from M. autumnalis ripe fruit (FFM), and evaluate its DPPH scavenging, anti-lipase, cytotoxicity, antimicrobial and antidiabetic effects. An ethyl acetate extract of M. autumnalis was subjected to a sequence of silica gel column chromatography using different eluents with various polarities. The chemical structures of the isolated compounds were identified using different spectral techniques, including 1H NMR and 13C NMR. FFM’s anti-diabetic activity was assessed using a glucose transporter-4 (GLUT4) translocation assay, as well as an inhibition against α-amylase and α-glucosidase using standard biochemical assays. The FFM anti-lipase effect against porcine pancreatic lipase was also evaluated. Moreover, FFM free radical scavenging activity using the DPPH test and antimicrobial properties against eight microbial strains using the micro-dilution method were also assessed. Four flavonoid aglycones were separated from FFM and their chemical structures were identified. The structures of the isolated compounds were established as kaempferol 1, luteolin 2, myricetin 3 and (+)-taxifolin 4, based on NMR spectroscopic analyses. The cytotoxicity test results showed high cell viability (at least 90%) for up to 1 mg/mL concentration of FFM, which is considered to be safe. A dose-dependent increase in GLUT4 translocation was significantly shown (p < 0.05) when the muscle cells were treated with FFM up to 0.5 mg/mL. Moreover, FFM revealed potent α-amylase, α-glucosidase, DPPH scavenging and porcine pancreatic lipase inhibitory activities compared with the positive controls, with IC50 values of 72.44 ± 0.89, 39.81 ± 0.74, 5.37 ± 0.41 and 39.81 ± 1.23 µg/mL, respectively. In addition, FFM inhibited the growth of all of the tested bacterial and fungal strains and showed the greatest antibacterial activity against the K. pneumoniae strain with a MIC value of 0.135 µg/mL. The four flavonoid molecules that constitute the FFM have been shown to have medicinal promise. Further in vivo testing and formulation design are needed to corroborate these findings, which are integral to the pharmaceutical and food supplement industries.

The results of many scientific studies indicate the importance of emotional intelligence in different aspects of life (professional and educational life). Therefore, educational institutions paid attention to it and this interest is represented in the development of its programs to include the emotional and social aspects. The aim of the research is to identify the relationship between emotional intelligence skills and the trend toward life, and to indicate whether the trend towards life can be predicted through emotional intelligence skills, and which of these skills are more significant in influencing the direction of life. The measurement tools were (Emotional Intelligence Skills Scale - A measure of the direction towards life). The research sample consisted of (210) students from the College of Education at Sultan Qaboos University in the academic year 2016-2017. The results of the study indicated that there is a statistically significant relationship between emotional intelligence skills and life orientation. The value of (P) was 15.343. which is a statistical function at the level of (0.01), indicating the effectiveness of predicting the impact of emotional intelligence skills, which is the subject of research on the trend towards life. The results also show that the skill (understanding others’ emotions interacting with others) was the most influential factor in the direction of life.

The data presented in this article are related to the research article entitled “Regulation of GLUT4 activity in myotubes by 3-O-methyl-D-glucose” (Shamni et al., 2017) [1]. These data show that the experimental procedures used to analyze the effects of 3-O-methyl-D-glucose (MeGlc) on the rate of hexose transport into myotubes were valid and controlled. The stimulatory effect of MeGlc was limited to glucose transporter 4 (GLUT4) and was independent of ambient glucose and protein synthesis. Cornish-Bowden kinetic analysis of uptake data revealed that MeGlc attenuated indinavir-induced inhibition of hexose transport in a competitive manner.

Type 2 diabetes (T2D) is a chronic metabolic disease, which could affect the daily life of patients and increase their risk of developing other diseases. Synthetic anti-diabetic drugs usually show severe side effects. In the last few decades, plant-derived drugs have been intensively studied, particularly because of a rapid development of the instruments used in analytical chemistry. We tested the efficacy of Gundelia tournefortii L. (GT) in increasing the translocation of glucose transporter-4 (GLUT4) to the myocyte plasma membrane (PM), as a main strategy to manage T2D. In this study, GT methanol extract was sub-fractionated into 10 samples using flash chromatography. The toxicity of the fractions on L6 muscle cells, stably expressing GLUTmyc, was evaluated using the MTT assay. The efficacy with which GLUT4 was attached to the L6 PM was evaluated at non-toxic concentrations. Fraction 6 was the most effective, as it stimulated GLUT4 translocation in the absence and presence of insulin, 3.5 and 5.2 times (at 250 μg/mL), respectively. Fraction 1 and 3 showed no significant effects on GLUT4 translocation, while other fractions increased GLUT4 translocation up to 2.0 times. Gas chromatography–mass spectrometry of silylated fractions revealed 98 distinct compounds. Among those compounds, 25 were considered anti-diabetic and glucose disposal agents. These findings suggest that GT methanol sub-fractions exert an anti-diabetic effect by modulating GLUT4 translocation in L6 muscle cells, and indicate the potential of GT extracts as novel therapeutic agents for T2D.

Estrogenic molecules have been reported to regulate glucose homeostasis and may be beneficial for diabetes management. Here, we investigated the estrogenic effect of β-sitosterol-3-O-D-glucopyranoside (BSD), isolated from the fruits of Cupressus sempervirens and monitored its ability to regulate glucose utilization in skeletal muscle cells. BSD stimulated ERE-mediated luciferase activity in both ERα and ERβ-ERE luc expression system with greater response through ERβ in HEK-293T cells, and induced the expression of estrogen-regulated genes in estrogen responsive MCF-7 cells. In silico docking and molecular interaction studies revealed the affinity and interaction of BSD with ERβ through hydrophobic interaction and hydrogen bond pairing. Furthermore, prolonged exposure of L6-GLUT4myc myotubes to BSD raised the glucose uptake under basal conditions without affecting the insulin-stimulated glucose uptake, the effect associated with enhanced translocation of GLUT4 to the cell periphery. The BSD-mediated biological response to increase GLUT4 translocation was obliterated by PI-3-K inhibitor wortmannin, and BSD significantly increased the phosphorylation of AKT (Ser-473). Moreover, BSD-induced GLUT4 translocation was prevented in the presence of fulvestrant. Our findings reveal the estrogenic activity of BSD to stimulate glucose utilization in skeletal muscle cells via PI-3K/AKT-dependent mechanism.

The importance of “study skills” has been increasingly emphasized by several researchers particularly at the university level where the student is independent and bears the responsibility of his/her own learning. Relevant research findings have indicated that positive changes in academic achievement are attributable to the various study skills possessed by the learners as relevant to the learning process. This study aims to investigate differences in “study skills” among a sample of SQU students in light of some variables. The measurement tool for the present research is a study skills measure that has been prepared and validated through factorial validity, and its reliability established through the Alpha Chronbach’s equation. Results show that there are no significant differences attributable to gender or the specialty area in the dimensions of the study skills investigated (study competencies, concentration during study, academic persistence, and readiness for exams). Further, the results also show no significant differences between the students of low and high GPA in the dimension of academic persistence. However, the results reveal significant differences between the students of low and high GPA in the dimensions of study competencies, concentration during study, and readiness for exams. These significant differences were in favor of the students of high GPA.

Naturally derived drugs and plant-based products are attractive commodities that are being explored for cancer treatment. This in vitro study aimed to investigate the role of Hypericum triquetrifolium (50% ethanol: 50% water) extract (HTE) treatment on apoptosis, cell cycle modulation, and cell cycle arrest in human colon cancer cell line (HCT-116). HTE induced cell death via an apoptotic process, as assayed by an Annexin V-Cy3 assay. Exposing HCT-116 cells to 0.064, 0.125, 0.25, and 0.5 mg/mL of HTE for 24 h led to 50 ± 9%, 71.6 ± 8%, 85 ± 5%, and 96 ± 1.5% apoptotic cells, respectively. HCT-116 cells treated with 0.25 and 0.5 mg/mL HTE for 3 h resulted in 38.9 ± 1.5% and 57.2 ± 3% cleavage of caspase-3-specific substrate, respectively. RT-PCR analysis revealed that the HTE extract had no effect on mRNA levels of Apaf-1 and NOXA. Moreover, the addition of 0.125 mg/mL and 0.25 mg/mL HTE for 24 h was clearly shown to attenuate the cell cycle progression machinery in HCT-116 cells. GC/MS analysis of the extract identified 21 phytochemicals that are known as apoptosis inducers and cell cycle arrest agents. All the compounds detected are novel in H. triquetrifolium. These results suggest that HTE-induced apoptosis of human colon cells is mediated primarily through the caspase-dependent pathway. Thus, HTE appears to be a potent therapeutic agent for colon cancer treatment.

Background: Loop electrosurgical excision procedure may be performed under local anesthesia or general anesthesia, and practice patterns differ worldwide. No randomized head-to-head comparison has been published to confirm or refute either practice., Objective: This study aimed to compare loop electrosurgical excision procedure under local anesthesia vs general anesthesia regarding patient satisfaction and procedure-related outcomes such as rates of involved margins, complications, pain, and blood loss., Study Design: Consecutive women referred to our colposcopy unit were recruited. Loop electrosurgical excision procedure was performed under local anesthesia with 4 intracervical injections of bupivacaine hydrochloride 0.5% or under general anesthesia with fentanyl, propofol, and a laryngeal mask with sevoflurane maintenance. The primary endpoint was patient satisfaction assessed on the day of surgery and 14 days thereafter using a Likert scale (score 0-100) and a questionnaire. Secondary endpoints included rates of involved margins, procedure-related complications, pain, blood loss, and surgeon preference. Results were compared using nonparametric and chi-square tests., Results: Between July 2018 and February 2020, we randomized 208 women, 108 in the local anesthesia arm and 100 in the general anesthesia arm. In the intention-to-treat analysis, patient satisfaction did not differ between the study groups directly after surgery (Likert scale 100 [90-100] vs 100 [90-100]; P=.077) and 14 days thereafter (Likert scale 100 [80-100] vs 100 [90-100]; P=.079). In the per-protocol analysis, women in the local anesthesia arm had significantly smaller cone volumes (1.11 cm 3 [0.70-1.83] vs 1.58 cm 3 [1.08-2.69], respectively; P<.001), less intraoperative blood loss (Δhemoglobin, 0.2 g/dL [-0.1 to 0.4] vs 0.5 g/dL [0.2-0.9]; P<.001), and higher satisfaction after 14 days (100 [90-100] vs 100 [80-100]; P=.026), whereas surgeon preference favored general anesthesia (90 [79-100] vs 100 [90-100], respectively; P=.001). All other secondary outcomes did not differ between groups (resection margin status R1, 6.6% vs 2.1% [P=.26]; cone fragmentation, 12.1% vs 6.3% [P=.27]; procedure duration, 151.5 seconds [120-219.5] vs 180 seconds [117-241.5] [P=.34]; time to complete hemostasis, 60 seconds [34-97] vs 70 seconds [48.25-122.25] [P=.08]; complication rate, 3.3% vs 1.1% [P=.59]). In a multivariate analysis, parity (P=.03), type of transformation zone (P=.03), and cone volume (P=.02) and not study group assignment, age, body mass index, and degree of dysplasia independently influenced the primary endpoint., Conclusion: Loop electrosurgical excision procedure under local anesthesia is equally well tolerated and offers patient-reported and procedure-related benefits over general anesthesia, supporting the preferred practice in some institutions and refuting the preferred practice in others., (Copyright © 2020 Elsevier Inc.

Background: Menopausal hormone therapy (MHT) is an appropriate treatment for women with the climacteric syndrome. The estrogen component of MHT effectively alleviates climacteric symptoms but also stimulates the endometrium and thus may increase the risk of endometrial cancer (EC)., Materials and Methods: We performed a systematic literature search of the databases PubMed and Cochrane Central Register of Controlled Trials to identify controlled and uncontrolled clinical trials reporting on the prevalence and/or incidence of EC among women using MHT., Results: 31 publications reporting on 21,306 women with EC diagnosed during or after MHT were identified. A significantly reduced risk of EC among continuous-combined (cc)MHT users with synthetic progestins (SPs) was demonstrated in 10/19 studies with odds ratios (ORs)/hazard ratios (HRs) between 0.24 and 0.71. Only one study documented an increased risk of EC among long-term users (≥10 years), not confirmed in three other sub-group analyses of women with ≥6, ≥5, and >10 years of ccMHT use. A significantly increased risk of EC among users of sequential-combined (sc)MHT with SPs was demonstrated in 6/12 studies with ORs/HRs between 1.38 and 4.35. Number of days of progestin per month was a significant modulator of EC risk. A decreased risk of EC was seen in obese women. Two studies documented an increased risk of EC among users of cc/scMHT with micronized progesterone. A significantly increased risk of EC among estrogen-only MHT users was demonstrated in 9/12 studies with ORs/HRs between 1.45 and 4.46. The adverse effect of estrogen-only MHT was greatest among obese women., Conclusion: ccMHT with SPs reduces the risk of EC, whereas estrogen-only MHT increases the risk. scMHT with SPs and cc/scMHT with micronized progesterone increase the risk of EC depending on type of progestin, progestin dosage, and duration of MHT use.

Background: Application of acetic acid to the cervix followed by colposcopic assessment with or without colposcopically directed biopsy is the standard test used to detect dysplastic lesions of the cervix. However, there is no evidence-based common standard defining how exactly to perform this test., Objective: To prospectively define the optimal timing for the colposcopic assessment of acetowhite lesions., Materials and Methods: Consecutive women referred to our colposcopy unit were recruited. Using a standardized colposcopy protocol, we recorded the most severe colposcopic lesion 1, 3, and 5 minutes after application of acetic acid (primary study end point). The time to first appearance of the most severe colposcopic lesion, highest staining intensity, and fading of the most severe colposcopic lesion were video documented (secondary study end points, assessed independently by 3 raters). Results were compared using parametric and nonparametric tests., Results: A total of 300 women were included. After 1 minute, 290 of 300 patients (96.7%) were diagnosed with the most severe colposcopic lesion. This proportion did not improve after 3 minutes (290/300 [96.7%]) or after 5 minutes (233/264 [88.3%]). The proportion of minor and major changes continuously declined over time from 142 in 300 (47.3%; 1 minute) to 107 in 264 (40.5%; 5 minutes) and from 110 in 300 (36.7%) to 91 in 264 (34.5%), respectively. The median time until the first appearance of the most severe colposcopic lesion was 13.5 (interquartile range, 3-27.25) seconds and was significantly lower in high-grade squamous intraepithelial lesion (7 [interquartile range, 1-20] seconds) compared to low-grade squamous intraepithelial lesion (19 [interquartile range, 9-39.5] seconds; P < .001). We observed fading of acetowhite lesions in 78% of cases, occurring at a median of 191 (interquartile range, 120-295) seconds after application of acetic acid. Fading started earlier in high-grade squamous intraepithelial lesion compared to low-grade squamous intraepithelial lesion (179.5 [interquartile range, 110- 253.25] versus 212.5 [interquartile range, 146.5-300]; P = .044). Overall, the net difference between colposcopic assessments at 3 minutes versus at 1 minute was 1 more high-grade squamous intraepithelial lesion and 1 less low-grade squamous intraepithelial lesion., Conclusion: It is reasonable to conclude that the best time to identify lesions is 1 minute after the application of acetic acid. Continued evaluation for up to 3 minutes may be considered reasonable for an optimal high-grade squamous intraepithelial lesion yield. However, fading of acetowhite lesions is common, especially in high-grade squamous intraepithelial lesions, and supports a recommendation of not prolonging colposcopy beyond 3 minutes., (Copyright © 2020 Elsevier Inc.

Cervical cancer is the fourth most common cancer in women worldwide, and early detection of its precancerous lesions can decrease mortality. Cytopathology, HPV testing, and histopathology are the most commonly used tools in clinical practice. However, these methods suffer from many limitations such as subjectivity, cost, and time. Therefore, there is an unmet clinical need to develop new noninvasive methods for the early detection of cervical cancer. Here, a novel noninvasive, fast, and label-free approach with high accuracy is presented using liquid-based cytology Pap smears. CARS and SHG/TPF imaging was performed at one wavenumber on the Pap smears from patients with specimens negative for intraepithelial lesions or malignancy (NILM), and low-grade (LSIL) and high-grade (HSIL) squamous intraepithelial lesions. The normal, LSIL, and HSIL cells were selected on the basis of the ratio of the nucleus to the cytoplasm and cell morphology. Raman spectral imaging of single cells from the same smears was also performed to provide integral biochemical information of cells. Deep convolutional neural networks (DCNNs) were trained independently with CARS, SHG/TPF, and Raman images, taking into account both morphotextural and spectral information. DCNNs based on CARS, SHG/TPF, or Raman images have discriminated between normal and cancerous Pap smears with 100% accuracy. These results demonstrate that CARS/SHG/TPF microscopy has a prospective use as a label-free imaging technique for the fast screening of a large number of cells in cytopathological samples.

Background: Chronic ectopic pregnancy (CEP) is a variant of ectopic pregnancy (EP) characterized by low or absent serum human chorionic gonadotropin (hCG) levels, resistance to methotrexate (MTX), and an adnexal mass with fibrosis, necrosis, and blood clots due to repeated and gradual fallopian tube wall disintegration. CEP may complicate the course of patients with EP and is difficult to diagnose., Case Presentation: The case of a 36-year-old woman with EP, low serum hCG levels, a small echogenic adnexal mass, and resistance to MTX is presented. Salpingectomy was performed and histology demonstrated CEP with fibrosis, necrosis, and a hematocele within degenerated chorionic villi., Systematic Literature Review: In a database search, 19 case reports, 3 case-control studies, and 3 case series describing 399 patients with CEP were identified. Serum hCG was negative in 40/124 cases (32%) with reported levels of serum hCG. The most common presenting symptom was abdominal pain (284/399 [71%]), followed by irregular vaginal bleeding (219/399 [55%]), and fever (20/399 [5%]). 73/399 (18%) women were asymptomatic. An adnexal mass was seen in 144/298 (48%) cases with perioperative ultrasound examination and with a mean largest diameter of 6.8 cm. Data on treatment modalities and outcomes were available for 297 women. Of these, 89% underwent surgery as first-line therapy. Laparoscopy was performed in most cases. MTX was the first-line therapy in a minority of cases. Complete resolution was achieved by first-line therapy in 287/297 (97%) cases. Adverse events were reported in 218 patients with CEP. Among those, adverse events ≥ grade 3 were seen in 186/218 (85%) cases. There was no case of treatment-related mortality., Conclusion: CEP is a variant of EP with low or absent trophoblast activity. A prolonged clinical course is typical and surgery is the mainstay of treatment.

Cytoreductive surgery (CRS) is an appropriate treatment for selected patients with endometrial cancer (EC)-derived peritoneal metastases (PM). Hyperthermic intraperitoneal chemotherapy (HIPEC) may enhance the therapeutic efficacy of CRS in these patients. We performed a systematic literature search of the databases PubMed and Cochrane Central Register of Controlled Trials to identify clinical trials and case reports reporting on the safety and efficacy of CRS and HIPEC in patients with EC-derived PM. Eight publications reporting on 68 patients were identified. The mean patient age was 57.1 years and the mean time from initial treatment of EC to CRS and HIPEC was 22.3 months. 41/64 patients had adenocarcinomas, type II cancers were present in 23/64 patients. The mean peritoneal carcinomatosis index (PCI) was 16.7. A complete surgical resection CC-0 was achieved in 44/63 (70%) patients. The chemotherapy regimens used for HIPEC were variable, but all included cisplatin, administered either alone (39/68 patients) or combined with doxorubicin or paclitaxel or mitomycin (29/68 patients). The duration of HIPEC was 60 min in 51/68 patients and 90 min in 17/68 patients. Mostly, the closed technique was used (55/68 patients). Adverse events grades 1/2, 3, and 4 were observed in 23/63, 12/63, and 6/63 patients, respectively. Treatment-associated mortality was 1% (1/63). After CRS and HIPEC, most patients received systemic chemotherapy (46/63 patients). Median disease-free and overall survival ranged from 7 to 18 and 12 to 33 months, respectively. In conclusion, CRS and HIPEC in EC with PM is safe and feasible. An additional therapeutic value of HIPEC is suggested, but prospective comparative trials are warranted.

Background: Acute colonic pseudo-obstruction or Ogilvie's syndrome (OS) is a rare form of postsurgical or posttraumatic complication. OS rarely occurs in the postoperative course of gynecologic and obstetric patients and is difficult to diagnose., Case Presentation: We present the case of an 83-years-old patient with carcinosarcoma of the uterus who developed OS with non-obstructive dilation of the right hemicolon and intraabdominal compression after total abdominal hysterectomy, omentectomy, and lymphadenectomy. Laparotomy with colonic decompression and abdominal dressing was performed. Subsequently, the patient developed pneumonia and peritonitis and died due to septic shock., Systematic Literature Review: We identified 49 case reports and 10 case series describing 17 gynecologic (cervical cancer, n = 2; carcinosarcoma of the uterus, n = 1; benign gynecologic condition, n = 14) and 76 obstetric patients (cesarean section, n = 66; OS during pregnancy or after vaginal delivery, n = 10). Outcome data were available for 59 patients. First-line treatment was conservative in 22/59 (37%) cases, laparotomy with decompression or colon resection was performed in 20/59 (34%) cases, endoscopic decompression in 12/59 (20%) cases, and i.v. neostigmine in 4/59 (7%) cases. Resolution was achieved in 22/59 (37%) of patients. The most common second-line treatment was right hemicolectomy. Adverse events grade 3 and 4 were observed in 8/59 and 31/59 patients (together 66%), respectively, mortality was 3/59 (5%)., Conclusion: OS is a rare postoperative complication of gynecologic and obstetric patients with a good prognosis, but a high morbidity. Pregnancy seems to be a predisposing factor for OS. Conservative treatment is a successful first-line approach.

Purpose: Calprotectin, a marker of acute and chronic inflammation, may play a role in pregnancy-associated disorders. We aimed to summarize available clinical data on calprotectin in pregnancy and to establish normal values of calprotectin during the course of pregnancy., Methods: We performed a systematic review of the databases PubMed and Cochrane Central Register of Controlled Trials to identify experimental and clinical evidence assessing the role of calprotectin in pregnancy. In addition, we performed a prospective cohort study assessing serum and urine calprotectin throughout pregnancy., Results: We identified 17 studies investigating 1638 pregnant women, 151 newborns, and 99 non-pregnant controls, measuring calprotectin in different compartments. Calprotectin was present in meconium and elevated in fecal samples of pregnant women with active inflammatory bowel disease. In women with pregnancy-induced hypertension, mild and severe preeclampsia (PE), calprotectin was significantly elevated in maternal plasma and serum, but not in fetal serum, amniotic fluid, and umbilical cord blood. For the cohort study, we recruited 196 pregnant women. PE and concomitant renal disease were present in 6/196 (3%) and 11/196 (5.6%) of women, respectively. Throughout pregnancy, median serum and urine levels of calprotectin largely exceed reported concentrations of the healthy non-pregnant population, but showed no significant variations between trimesters 1-3 and post-partum. Calprotectin in serum was correlated with systolic blood pressure and in urine with leukocytes and total protein. No significant differences were found in subgroup analyses of smokers vs. non-smokers, PE vs. none, and renal disease (kidney stones, reflux) vs. none., Conclusion: Calprotectin concentrations in amnion fluid and stools serve as potential indicators of inflammatory states during pregnancy. Urinary calprotectin concentrations are continuously high during pregnancy and show no significant variations between trimesters 1-3 and post-partum.

Purpose: The aim of the present study was to assess the value of the Glasgow Prognostic Score (GPS) as a prognostic tool for predicting post-relapse survival (PRS) in patients with recurrent cervical cancer., Methods: We retrospectively evaluated the data of 116 patients with recurrent cervical cancer in whom serologic biomarkers had been assessed at the time of relapse. The GPS was calculated as follows: patients with elevated serum C-reactive protein levels and hypoalbuminemia were allocated a score of 2, and those with 1 or no abnormal value were allocated a score of 1 and 0, respectively. To assess the association between factors including the GPS and PRS, we performed uni- and multivariate survival analyzes., Results: After a median follow-up of 20.9 months from recurrence, a 5-year PRS rate of 25% (SE 4.7%) was observed. Only in 29.8% of the patients, recurrence was limited to the pelvis. In uni- and multivariate survival analyzes, the GPS [HR 1.6 (95% CI 0.9-2.4), p = 0.01], a history of radiation therapy as part of initial treatment [HR 2.7 (95% CI 1.1-6.9), p = 0.03], and the presence of peritoneal carcinomatosis or multiple sites of relapse [HR 4.2 (95% CI 1.9-9.3), p < 0.001] were associated with shorter PRS. The GPS correlated with higher squamous cell carcinoma antigen levels (p = 0.001), shorter median PRS (p = 0.009), and less intensive treatment for relapse (p = 0.02)., Conclusions: A higher GPS at the time of relapse, a history of radiation therapy, and the presence of peritoneal carcinomatosis or multiple sites of relapse are independently associated with shorter PRS in patients with recurrent cervical cancer.

Background: The members of the slit homolog (SLIT) and roundabout homolog (ROBO) families have emerged as important signaling molecules in tumor metastasis. This study analyzed their role in regulating breast cancer (BC) cell motility and chemotaxis and assessed expression of ROBO1 in brain metastases (BMs) of breast, lung, and colon cancer, and in peritoneal metastases (PMs) of ovarian cancer., Materials and Methods: The BC cell line MDA-MB231 was subjected to scratch, motility, and chemotaxis assays using heparin and a purified recombinant N-terminal SLIT2 fragment. Protein expression was assessed in primary tumors and metastases by immunohistochemistry., Results: Exposure to SLIT2 induced MDA-MB231 cell motility, but no significant chemotaxis without the presence of heparin. ROBO1 was expressed in 4/5 primary BC and in 18/21 BC-derived BM samples; 7/9 BM primary lung cancer samples also stained positive. In contrast, BMs from colorectal cancer were negative for ROBO1. Primary ovarian cancer and ovarian PM showed ROBO1 expression in 0/6 and in only 2/6 samples, respectively, whereas SLIT2 was observed in 1/6 primary cancer and in 6/6 PMs samples., Conclusion: SLIT2 can induce BC cell motility and chemotaxis, but the latter requires the presence of heparin. BM expression of ROBO1 is a common feature of some, but not all cancer types. SLIT2 expression appears to be a general feature of ovarian cancer-derived PMs., (Copyright© 2019, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

Purpose: The Internet has become a widely used source of healthcare information. Many Departments of Obstetrics and Gynecology use their websites for public relations purposes. It is, however, unclear, what relevant stakeholders such as patients, relatives of patients, physicians, and medical students expect of an Obstetrics and Gynecology Department's website. Therefore, we evaluated the opinions and expectations of the various stakeholders using a structured questionnaire., Methods: We asked gynecologic patients, obstetric patients, relatives of patients, medical students, and physicians to fill in an anonymous questionnaire consisting of general facts about the informant, one open-ended question on expectations and wishes regarding the website, and 28 rating scale questions (7-step visual analog scale ranging from, not important' to, very important') covering the topics "website navigation" (4 questions), "first contact" (3 questions), "clinic processes" (7 questions), "facts and figures about the Department" (4 questions), "visual impressions" (5 questions), and "obstetrics-specific items" (5 questions). Questionnaires for physicians included four additional questions about the value of Department websites as an information tool for themselves and their patients. We used descriptive statistics to analyze the data., Results: 1458 questionnaires were analyzed (gynecologic patients, n = 615 [42%]; obstetric patients, n = 479 [33%]; relatives of patients, n = 77 [5%]; medical students n = 238 [16%]; physicians, n = 41 [3%]). The number of circulated questionnaires was not recorded and thus, the response rate is unknown. 1304 (89%) respondents used the Internet as a regular source of health care information, 642 (44%) had previously searched an Obstetrics and Gynecology Department website. All respondents rated contact data and information about processes in the clinic highest; whereas, other issues such as medical facts, visual impressions, and website design issues were significantly less important. Pregnant women rated contact information and obstetric facts highest. 90% of physicians regularly used Department websites for patient referrals and rated contact information and medical team details most important., Conclusions: When designing a website of an Obstetrics and Gynecology Department, contact information and information about processes in the clinic should be displayed most prominently and be easily accessible. Subsections specifically targeted at obstetric patients and physicians should be provided.

Introduction In connection with the reorganisation of cervical carcinoma screening, the importance of colposcopy as an integral part of the planned series of clarification testing will greatly increase. Quality standards for performing the colposcopic examination should therefore be defined in detail. A precondition for this is surveying the current standard in clinical practice. The objective of this study was to evaluate the current practice of colposcopy and conisation in Germany by means of a questionnaire aimed at gynaecologists who perform colposcopies in order to document the actual therapeutic standard of treatment of cervical dysplasia. Materials and Methods Gynaecologists were invited via e-mail or during events to participate in a web-based survey. The questionnaire contained 38 questions on management before, during and after the examination as well as questions on the technical implementation of colposcopy and conisation. Results From February 2018 to April 2018, 961 e-mails were sent. A response was received in 197 cases (response rate 20.5%). Responses were received for another 40 questionnaires during events (response rate approx. 80%). After taking the inclusion criteria into account, 160 questionnaires were evaluated. The majority of those surveyed take an average of 2 cervical biopsies (67.3%) and nearly all of those surveyed (94.5%) do not use any local anaesthetic. As a standard method for removing cervical precancerous cells, most of the physicians surveyed perform a loop excision with the electrosurgical loop (91.2%) under colposcopic visualisation (61.2%) under general anaesthesia (92.5%). Postoperative bleeding prophylaxis by means of tamponade is performed only in 27.6% of all cases. Conclusion A differential colposcopy with two colposcopically targeted biopsies and treatment with the electrosurgical loop are the methods most frequently used by clinicians who perform colposcopy in Germany. A uniform procedure should be defined in detail within the scope of directives or guidelines.

Background: A change of cervical cancer screening algorithms to an HPV-based screening setting is discussed in many countries, due to higher sensitivity of HPV testing compared to cytology. Reliable triage methods are, however, an essential prerequisite in such a setting to avoid overtreatment and higher screening costs., Results: In this study, a series of cervical scrapes collected in PreservCyt liquid-based cytology (LBC) medium from women with cervical cancer (n = 5), cervical intraepithelial neoplasia grade 1-3 (n = 74), and normal cytology (n = 201; further n = 352 collected in SureThin®) were assessed for methylation of the marker regions ASTN1, DLX1, ITGA4, RXFP3, SOX17, and ZNF671 using the GynTect assay and compared to cobas® HPV and CINtec Plus® biomarker results. All samples from women with cervical cancer, 61.2% of CIN3, 44.4% of CIN2 and 20.0% of CIN1 cases were scored positive for the GynTect methylation assay. In contrast, all CIN, irrespective of severity grade, and carcinomas were positive by both, CINtec Plus and cobas HPV. The specificity of GynTect for CIN3+ was 94.6% compared to 69.9% for CINtec Plus and 82.6% for cobas HPV (all HPV types) and 90.6% for cobas HPV 16/18. DNA methylation analysis of this methylation marker panel (GynTect assay) in cervical scrapes consistently detects cervical cancer and the majority of CIN3 as well as a subset of CIN1/2 lesions. The detection rate among cytologically normal samples is extraordinarily low (1.5%)., Conclusion: GynTect shows excellent performance when using cervical scrape material collected in liquid-based cytology media, a prerequisite for employing such a test as a triage in screening programs. Compared to the other test systems used in this work, GynTect showed higher specificity while still detecting all cancer cases.

Objective: To test whether music by Mozart reduces anxiety among patients undergoing colposcopy., Methods: In a randomized multicenter trial, we measured the reduction of the situation-specific anxiety of women hearing Mozart's Symphony No. 40 during colposcopy compared with women not hearing music using the State-Trait Anxiety Inventory. Secondary endpoints were reduction of heart rate (beats per minute), pain during and 10 minutes after colposcopy, general unpleasantness, anxiety during colposcopy, and overall satisfaction (11-item visual analog scales). Analysis was by intention to treat. A sample size of 104 per group (N=208) was calculated to achieve 80% power to detect a difference of 4.8 with a SD of 12.3 in anxiety scores., Results: Between February 2017 and May 2018, 212 women were randomized. The mean anxiety reduction was -9.4±10.8 SD in 103 women in the music group and -9.0±10.6 in 102 women in the control group (P=.40). The secondary endpoints reduction of heart rate (-16.3±16.9 vs -15.4±17.1; P=.37), pain during procedure (median 2 [interquartile range 1-4] vs 2 [1-3.5]; P=.80), pain 10 minutes after examination (1 [0-1.75] vs 1 [0-2]; P=.42), general unpleasantness (3 [1-5.75] vs 4 [1-5.5]; P=.35), anxiety during examination (2 [1-5] vs 2 [1-6]; P=.28), and overall satisfaction (10 [9-10] vs 10 [9-10]; P=.81) were also not different between the two study groups., Conclusion: Mozart's Symphony No. 40 does not reduce anxiety in women undergoing colposcopy., Clinical Trial Registration: ClinicalTrials.gov, NCT03005795.

Background: Loop electrosurgical excision procedure is the standard surgical treatment for cervical dysplasia. Loop electrosurgical excision procedure is advised to be performed under colposcopic guidance to minimize adverse pregnancy outcomes. To date, there is no evidence from randomized trials for this recommendation., Objective: We sought to assess the benefits of performing loop electrosurgical excision procedure under colposcopic guidance in women with cervical dysplasia., Study Design: In a prospective, randomized trial, we compared loop electrosurgical excision procedure with loop electrosurgical excision procedure performed under direct colposcopic vision in a 1:1 ratio. The primary endpoint was resected cone mass; the secondary endpoints were margin status, fragmentation of the surgical specimen, procedure time, time to complete hemostasis, blood loss, and intraoperative and postoperative complications. A sample size of 87 per group (n = 174) was planned (with an assumed type I error of 0.05 and drop-out rate of 5%) to achieve 90% power to detect a 25% reduction in cone mass (with an assumed cone mass of 2.5 ± 1.6 g in the control group) using a nonparametric test (Mann-Whitney U)., Results: From October 2016 through December 2017, we randomized 182 women: 93 in the loop electrosurgical excision procedure group and 89 in the loop electrosurgical excision procedure-direct colposcopic vision group. Women undergoing loop electrosurgical excision procedure-direct colposcopic vision had significantly smaller cone specimens than those undergoing loop electrosurgical excision procedure (weight: median 1.86 [interquartile range 1.20-2.72] vs median 2.37 [interquartile range 1.63-3.31] g, respectively, P = .006). Secondary outcome measures did not differ significantly between groups: resection margin status involved vs free margin: 12 (13%) vs 75 (82%) and 11 (12.4%) vs 75 (84.3%); fragmentation no vs yes: 85 (92.4%) vs 7 (7.6%) and 84 (94.4%) vs 5 (5.6%); procedure time: 190 (interquartile range 138-294) and 171 (interquartile range 133-290) seconds; time to complete hemostasis: 61 (interquartile range 31-108) and 51 (interquartile range 30-81) seconds; intraoperative blood loss (Δhemoglobin): 0.4 (interquartile range 0.2-1.0) and 0.5 (interquartile range 0.1-0.9); complication rate: 6 (6.5%) and 2 (2.2%). In a multivariate analysis, study group allocation (P = .021) and parity (P = .028), but not age, body mass index, type of transformation zone, and dysplasia degree independently influenced the amount of resected cone mass., Conclusion: Loop electrosurgical excision procedure with intraoperative colposcopy leads to significantly smaller cone specimens without compromising margin status., (Copyright © 2018 Elsevier Inc.

Background: Systemic chemotherapy is not effective in patients with peritoneal carcinomatosis (PC) and only a minority of affected patients is eligible for cytoreductive surgery. Intraperitoneal chemotherapy may provide a therapy alternative for these patients., Methods: We performed a systematic review of clinical and experimental evidence on the safety and efficacy of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in patients with PC and provide clinical recommendations based on the available evidence., Results: Fifty-eight reports were identified, categorized as experimental (18 reports), clinical (28 reports), and other articles (14 reports). Experimental studies demonstrated improved tissue penetration and peritoneal coverage. The 28 clinical studies reported on 3515 procedures in 1547 patients with PC of various primary tumors with 16 of these studies reporting on patients with ovarian cancer. Toxicity was manageable. Based on 1197 patients in 22 studies, adverse events CTCAE grades 1, 2, 3, 4, and 5 were observed in 537 (45%), 167 (14%), 83 (7%), 10 (0.8%), and 19 (1.6%) cases, respectively. In a pooled analysis, the objective tumor response rate was 69% and the mean overall survival duration was 13.7 months. No significant hepatic, renal, or hematologic toxicity was described. PIPAC maintained and/or improved quality of life, as reported in 10 studies with 396 patients., Conclusions: Available evidence from controlled trials (phase I and phase II) and retrospective cohort studies in > 1500 patients unequivocally demonstrates that PIPAC is feasible, safe, and effective. PIPAC maintains quality of life in patients with recurrent cancer and PC. PIPAC is as evidence-based as any other treatment in women with ovarian cancer and PC beyond the third line of systemic chemotherapy and can be recommended in this indication.

Introduction: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new means of delivering chemotherapy into the abdomen of patients with peritoneal carcinomatosis (PC). The amount of drug uptake in ascites and peritoneum after PIPAC is unknown., Methods: Retrospective cohort study of women with PC from gynecological tumors comparing the concentrations of cisplatin and doxorubicin in ascites and peritoneum before and after PIPAC. Concentrations were measured using gas chromatography. Peritoneal tumor samples were assessed for histological tumor regression., Results: 59 PIPAC procedures were performed in 32 women with PC. The concentrations of doxorubicin and cisplatin in ascites significantly increased after PIPAC (140.2 ± 671.5 vs 9035.7 ± 5328.6 ng/ml; p < 0.0001 and 95.2 ± 106.4 vs 24,770.8 ± 11,710.8 ng/ml; p < 0.0001, respectively). Concentrations of doxorubicin and cisplatin in peritoneal tissue also significantly increased after PIPAC (5.1 ± 0.7 vs 19.2 ± 38.6 ng/g; p = 0.007, and 81.9 ± 7.8 vs 131.5 ± 134.4 ng/g; p = 0.005, respectively). On an individual patient level, a significant uptake (>2-fold) of doxorubicin and cisplatin was observed in 57/59 (97%) and 58/59 (98%) of cases in ascites and in 23/59 (39%) and 13/59 (22%) of cases in the peritoneum. Uptake of cisplatin and doxorubicin were significantly correlated (Spearman correlation coefficient: 0.33; p = 0.011). After repeated PIPACs, doxorubicin uptake increased in peritoneal tumor tissue (p = 0.008)., Conclusions: PIPAC leads to a significant chemotherapy uptake in both ascites and peritoneum, suggesting a bimodal cytotoxic effect of PIPAC via direct tissue uptake into peritoneal tumor nodules and via ascites. Consecutive PIPAC applications lead to peritoneal accumulation of doxorubicin, suggesting a cumulative cytotoxic effect of doxorubicin after repeated PIPACs., (Copyright © 2018 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.
