Use of volumetric CT scanning to predict tumor staging and survival in pancreatic cancer patients that are to be administered curative resection.

BACKGROUND: This study evaluates the achievability of CT volumetry of pancreatic cancer and its correlation with pTNM stage and survival. METHODS: Tumor volume was measured from contrast enhanced CT images of 58 patients who undergo curative resection for pancreatic cancer using the Segment Editor module implemented in 3D-Slicer-a free open source software platform. Receiver operating characteristic (ROC) analysis was used to evaluate correlation between Tvol and pTNM staging. RESULTS: The preoperative images of 58 pancreatic adenocarcinoma patients were included. The mean Tvol of pancreatic cancer is an increasing trend with T stage (The mean T1vol = 1.75 cm3 , the mean T2vol = 11.43 cm3 , the mean T3vol = 14.98 cm3 , the mean T4vol = 19.6 cm3 ). There were statistical differences between volumes (p = .000). On ROC analysis, the area under the ROC curve (Az) of Tvol to differentiate T1 stage from ≥T2 stage was 0.966 (p = .000). At a cut-off value of 3.050 cm3 , sensitivity of 92.3%, and specificity of 83.3% were achieved. Az value of Tvol to differentiate ≤T2 from ≥T3 stage was 0.750 (p = .010). At a cut-off value of 10.250 cm3 , sensitivity of 72.7% and specificity of 66% were achieved. In addition Az value of Tvol to differentiate ≤T3 from ≥T4 stage was 0.652 and was not significant (p = .380). At a cut-off value of 11.2 cm3 , sensitivity of 66.7% and specificity of 63.6% were achieved. CONCLUSION: CT volumetry in pancreatic cancer is feasible with excellent reproducibility. It is one of the prognostic factors affecting survival in operated patients with pancreatic cancer.

2D:4D Digit Ratios in Adults with Gender Dysphoria: A Comparison to Their Unaffected Same-Sex Heterosexual Siblings, Cisgender Heterosexual Men, and Cisgender Heterosexual Women.

We compared gender dysphoria (GD) patients and their same-sex siblings in terms of their 2D:4D ratios, which may reflect prenatal exposure to androgen, one of the possible etiological mechanisms underlying GD. Sixty-eight GD patients (46 Female-to-Male [FtM]; 22 Male-to-Female [MtF]), 68 siblings (46 sisters of FtMs; 22 brothers of MtFs), and 118 heterosexual controls (62 female; 56 male) were included in the study. FtMs were gynephilic and MtFs were androphilic. We found that 2D:4D ratios in the both right hand (p < .001) and the left hand (p = .003) were lower in male controls than in female controls. Regarding right hands, FtM GD patients had lower 2D:4D ratios than female controls (p < .001) but their ratios did not differ from those of their sisters or male controls. FtM GD patients had no significant difference in their left-hand 2D:4D ratios compared to their sisters or female and male controls. While there was no significant difference in right hands between FtM's sisters and male controls, left-hand 2D:4D ratios were significantly higher in FtM's sisters (p = .017). MtF GD patients had lower right-hand 2D:4D ratios than female controls (p <.001), but their right-hand ratios did not differ from those of their brothers and male controls. There was no significant difference in left-hand 2D:4D ratios between MtF GD patients, and their brothers, or female and male controls. FtM GD patients showed significantly masculinized right-hand 2D:4D ratios, while there was no evidence of feminization in MtF GD patients.

Successful treatment of refractory secondary immune thrombocytopenia (antiphospholipid antibody syndrome-associated) with the combination of rituximab and romiplostim at the cost of severe bone pain: A case report and review of literature.

INTRODUCTION: Immune thrombocytopenia is an autoimmune disorder associated with increased thrombocyte destruction and impaired production in the bone marrow. Proposed mechanisms include an antibody or autoreactive T-cell-associated autoimmunity and thrombopoietin deficiency among others. Clinical manifestations are predominantly mucocutaneous hemorrhages including petechiae, purpura, mucosal bleeding in the urinary or the gastrointestinal tracts, menorrhagia, and epistaxis. The purpose of the treatment is to prevent bleeding rather than normalizing the platelet counts. First-line treatments include corticosteroids ± intravenous immunoglobulin and Anti-D which mainly decrease antibody-mediated platelet destruction and increase the number of peripheral Tregs. Second-line and subsequent therapies include splenectomy, chimeric anti-CD20 antibody (rituximab), which eliminates B cells and act as an immunomodulatory agent, and Thrombopoietin receptor agonists (romiplostim), which promote platelet production. CASE REPORT: We describe a 40-year-old male patient diagnosed with immune thrombocytopenia that was refractory to first-line corticosteroid and intravenous immunoglobulin and second-line romiplostim monotherapy treatments.Management and outcome: The patient was given the romiplostim and rituximab combination which not only successfully treated thrombocytopenia but also resulted in grade 3 bone pains and the patient's subsequent refusal to continue therapy. DISCUSSION: Common adverse effects of rituximab are infusion reactions and prolonged immunosuppression; those of romiplostim include thrombosis, headaches, arthralgia-myalgia, and gastrointestinal symptoms. This case shows that romiplostim has not caused any discernible side effects when given alone, while combination with rituximab resulted in severe bone and joint pains. We hypothesize that this combination regimen shows a synergistic effect both in terms of efficacy and adverse-effect probability and/or severity.

Anxiety levels and obsessive compulsion symptoms of pregnant women during the COVID-19 pandemic.

OBJECTIVE: Reliable data regarding maternal mental well-being during the Severe Acute Respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic are scarce. This study aimed to assess the state/trait anxiety and obsessive-compulsive symptoms of pregnant women and compare those with the non-pregnant population using patient-reported validated outcome measures. MATERIALS AND METHODS: This prospective case-control study was conducted at a tertiary 'Coronavirus Pandemic Hospital' in Istanbul, Turkey in April, 2020. Pregnant and non-pregnant women were consecutively allocated to two groups regardless of gestational age. The primary outcome was to identify the anxiety levels and obsessive-compulsive symptoms of pregnant women during the SARS-CoV-2 pandemic using the State-Trait Anxiety inventory (STAI) and Maudsley Obsessive-Compulsive inventory (MOCI), respectively. RESULTS: Two hundred three pregnant women and 101 non-pregnant women were included. The mean STAI-S questionnaire score of pregnant and nonpregnant women was 41.96±9.15 and 46.62±12, respectively (p=0.001). The overall incidence of STAI >40 in pregnant and non-pregnant women was 62.6% and 73.3%, respectively. The mean total score of MOCI was 17.9±6.7 and 15±6.6 in pregnant and non-pregnant women, respectively. The overall incidence of 30-item-MOCI ≥13.1 in pregnant and non-pregnant women was 61.6% (125/203) and 30.7% (31/103), respectively (p<0.001). CONCLUSION: State anxiety and obsessive-compulsive symptoms in pregnant women were found increased during the current SARS-CoV-2 pandemic. Pregnant women showed more favourable anxiety levels compared with non-pregnant women. These findings can be used to improve the coping skills of pregnant women during the pandemic, to prepare for the post-pandemic period, and to deal with the long-term mental health impact of COVID-19.

Near-term pregnant women's attitude toward, concern about and knowledge of the COVID-19 pandemic.

Background: COVID-19 is a novel type of the coronavirus family with an incompletely described clinical course. Little is known about the psychological aspects, particularly for vulnerable populations including pregnant women.Objectives: To understand the attitude, concerns, and knowledge of the non-infected pregnant women toward the COVID-19 outbreak in order to constitute base data for detailed counseling and to develop targeted messages.Patients and methods: This cross-sectional survey research presented analysis of prospectively collected data yielded at a single tertiary "Coronavirus Pandemic Hospital" referral center for a ten days period following the first confirmed death due to the COVID-19 pandemic in Turkey. Non-infected women with a confirmed pregnancy over 30th gestational week were consecutively included. A patient-reported non-validated questionnaire formed by the expert committee that includes 15 specific questions was used. Non-infected, pregnant women over 30th gestational week who applied to the outpatient clinic were consecutively included. A total of 213 women were enrolled, 37 were excluded: 7 for being in the first trimester, 3 were illiterate, and 27 were Syrian refugees having difficulties in translation.Results: A total of 172 pregnant women were included. Overall, four women refused to participate to the survey (1.9%). The mean age was 27.5 ± 5.3 years. Median gestational week and parity were 35 ± 11 weeks and 1 ± 2, respectively. Pregnant women were observed to trust the authorities (65%) and the healthcare staff (92.4%), and their respect was increased (82.5%) during the outbreak. Majority of the women (87.2%) comply with the self-quarantine rules. Half of the women (52%) reported that they felt vulnerable and predominantly were concerned (80%). Approximately one-third of the women constantly keep thinking that they may get infected (35.5%) or they might get infected during/following the delivery or their baby might get infected after being born (42%). Half of the women (50%) were reported that they either had no idea about or think the breastfeeding is not safe during the outbreak. About 45% of the women were confused or had doubts about if the mode of delivery may be affected by the pandemic. Greater part of the participants does not know if COVID-19 might cause birth defects (76%) or preterm birth (64.5%). Counseling flow keys helping pregnant women to overcome misleads, regarding the COVID-19 outbreak is proposed.Conclusions: Non-infected pregnant women with a viable pregnancy at near term were observed to have positive attitude and compliance toward the COVID-19 outbreak and frontline healthcare staff; increased concern and vulnerability; and restricted knowledge about the pregnancy-related outcomes. While the clinical evidence was growing rapidly, this data may guide obstetricians and midwives to perceive what accurate information should be provided to the pregnant women.

Patients with NSCLCs Harboring Internal Inversions or Deletion Rearrangements of the ALK Gene Have Durable Responses to ALK Kinase Inhibitors.

BACKGROUND: ALK fusions are targetable drivers in non-small-cell lung cancer (NSCLC). However, patients with NSCLC harboring ALK rearrangements without a fusion partner identified in DNA have also been shown to respond to ALK inhibitors. We aimed to characterize complex ALK variants that may predict sensitivity to multiple approved ALK inhibitors. METHODS: Comprehensive genomic profiling (CGP) of DNA isolated from formalin-fixed paraffin-embedded (FFPE) tumor tissue or blood-based circulating tumor DNA was performed for 39,159 NSCLC patients during routine clinical care. For a subset of cases, RNA sequencing was performed, and prior ALK test results and clinical treatment information were collected from treating physicians. RESULTS: We queried the Foundation Medicine NSCLC database and identified ALK internal inversions, as well as internal deletions, as the sole ALK rearrangements in 6 (0.02%) and 3 (0.01%) of cases, respectively. In cases with ALK internal inversions, RNA testing identified an EML4-ALK fusion in 2/2 cases evaluated, and 3/3 patients treated with ALK inhibitors had durable responses. A single patient with an ALK internal deletion and clinical data available responded to multiple ALK inhibitors. RNA data available for a subset of non-NSCLC cases suggest that ALK internal deletions removing a portion of the N-terminus are drivers themselves and do not result in ALK fusions. Fluorescence in situ hybridization (FISH) results were inconsistent for both classes of DNA events. CONCLUSION: Rare internal inversions of ALK appear to be indicative of ALK fusions, which can be detected in RNA, and response to ALK inhibitors in patients with NSCLC. In contrast, ALK internal deletions are not associated with ALK fusions in RNA but likely represent targetable drivers themselves. These data suggest that CGP of DNA should be supplemented with immunohistochemistry or RNA-based testing to further resolve these events and match patients to effective therapies.

The Influences of Whole Brain Radiotherapy on Social Cognition and Association with Hippocampal and Frontal Dosimetry.

The influence of brain radiotherapy on neurocognition is a major concern. Social cognition is a mental process in the meaning of social interaction and the recognition of facial emotion is a domain of social cognition. Thus, we aimed to investigate the early effect of whole brain radiotherapy on facial emotion recognition ability. Thirteen patients with various brain tumors in the study. Beck depression and anxiety inventory and the facial emotion recognition test by using a set of photographs were performed at the beginning and post radiotherapy. The severity of depression (16.40 ± 12.16 vs 04.00 ± 02.38 points) and anxiety (14.47 ± 11.96 vs 04.54 ± 03.30 points) were significantly higher in patients. The only significance according to facial emotion recognition rate between initial phase of patients and healthy controls was identifying neutral facial em otion (p = 0.002). The patients after brain radiotherapy had significantly better rate of recognizing fear facial emotions (p = 0.039). This study is the first that investigated the effects of cranial irradiation on facial emotion recognition ability and compares this ability with healthy controls. Interestingly, in the early phase the patients seem to be improved in fear facial emotion after brain radiotherapy without sparing cognition specific regions as hippocampus and frontal regions.

Factors associated with the duration of untreated illness among patients with obsessive compulsive disorder.

BACKGROUND: Patients suffering from obsessive compulsive disorder (OCD), despite heightened levels of functional impairment and disability, often wait several years before starting pharmacological treatment. The interval between the onset of a specific psychiatric disorder and administration of the first pharmacological treatment has been conceptualized as the duration of untreated illness (DUI). The DUI has been increasingly investigated as a predictor of long-term outcomes for OCD and other anxiety disorders. The present study investigated DUI, and demographic-clinical factors associated with DUI, among a sample of patients with OCD. The relationships between DUI, insight, and treatment outcomes were also assessed. METHODS: We evaluated 96 subjects with a DSM-IV diagnosis of OCD using the Structured Clinical Interview for DSM-IV Axis I disorders, a semistructured interview for sociodemographic and clinical features, the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and a questionnaire designed by our group to identify reasons for delaying psychiatric admission. Patients with OCD showed a mean DUI of 84 months. However, DUI was not predictive of remission defined by a Y-BOCS total score of 10. Using the median value, a categorical cut-off for DUI of 4 years was calculated. RESULTS: For patients with a shorter DUI (≤4 years), the age of OCD onset was significantly older than patients with a longer DUI (>4 years) (p<.001). The following four items related to reasons for delaying treatment were significantly endorsed by patients: the fact that symptoms were spontaneously fluctuating over time (61.5%), believing that OCD symptoms were not associated with an illness (60.4%), believing that one can overcome symptoms by him/herself (55.2%), and not being significantly disturbed by OCD symptoms (33.3%). Delaying treatment because of perceived social stigma was only endorsed by 12.5% of patients. Believing that OCD symptoms were not associated with an illness was significantly associated with a longer DUI (p=.039). CONCLUSIONS: Results from the present study suggest that patients with OCD show a significant inclination toward delaying treatment admission. However, DUI was not predictive of remission in terms of symptomatology. Believing that OCD symptoms are not associated with an illness might indicate impairment in insight, a denial of the problem or could be associated with awareness of OCD as a mental illness. Factors related to the nature and course of OCD appear to be important determinants in delaying treatment among patients with OCD.
