Spectral lines in FUV and EUV for diagnosing coronal magnetic field

The diagnostic capabilities of spectral lines in far ultraviolet (FUV) and extreme ultraviolet (EUV) wavelength range are explored in terms of their Hanle and Zeeman sensitivity to probe vector magnetic field in the solar corona. The temperature range covered is log$_{10}(T)=5.5-6.3$. The circular polarization signal due to longitudinal Zeeman effect is estimated for spectral lines in the wavelength range of 500 to 1600 \r{A}. The Stokes $V/I$ signal for a FUV line is found to be in the order of 10$^{-4}$ for a longitudinal field strength of 10 Gauss, which further reduces to 10$^{-5}$ for wavelengths below 1200 \r{A}. Due to such low signals, the present study aims to find combination of spectral lines having different Hanle sensitivity but with identical peak formation temperature to probe coronal magnetic field vector. The combination of Hanle sensitive lines is better suited because the Hanle signals are stronger by at least an order of magnitude compared to Zeeman signals. The linear polarization signals due to Hanle effect from at least two spectral lines are required to derive information on the full vector. It is found from this study that there is always a pair of Hanle sensitive lines for a given temperature range suitable for probing coronal vector magnetic field and they are located in close proximity with each other in terms of their wavelength.Comment: 22 pages, 2 figures, 1 table.

Evaluation of outcome of mode of delivery in severe preeclampsia

Background: Preeclampsia is new onset hypertension of more than 140/90 mmHg on 2 occasions, 4 hours apart in pregnancy, which occurs after 20 weeks of gestation and frequently near term. If there are other symptoms like as headache, blurred vision from end organ damage, and thrombocytopenia, it is characterized as severe preeclampsia. Regardless of the foetal outcome, treatment for severe preeclampsia is immediate delivery. The goal of the current study is to assess how different delivery methods affect individuals with severe preeclampsia.Methods: It is a retrospective study conducted in RL Jalappa hospital, Kolar from January 2021 to February 2022. Out of 2568 deliveries at our facility throughout the study period, 150 singleton pregnancies complicated by severe preeclampsia delivered at 24-34 weeks of gestation were chosen for the study. Women who had additional obstetric, foetal, or medical difficulties were not included in the study.Results: 110 study participants had an LSCS form of delivery out of the total. Among them, non-reassuring fetal heart rate, obstructed labor, and malpresentation were the most typical indicators for LSCS. The difference between Bishop's score and the mode of delivery was statistically significant. There was no discernible difference between the newborn's APGAR score immediately following delivery and the method of delivery.Conclusions: There are strong chances of a normal vaginal birth if the Bishop score at the time of admission and induction is more than 4

Semester Zero: an innovative orientation and nurturing program

The current Coronavirus (COVID-19) pandemic has affected many universities’ orientation as well as study programs. While some are still contemplating whether to open their doors for F2F studies, others face the challenge of fewer students enrolling due to travel restrictions. The University of the South Pacific (USP) will face a different kind of challenge. USP is a regional university co-owned by twelve South Pacific countries. Campuses and sub-campuses are situated in all these countries. Usually, orientation programmes are held at all campuses, but the majority of students travel early to USP’s main campus in Fiji for the orientation program. Due to COVID-19, students’ travel will be restricted, and the orientation programme will be a very small-scale event this year. Additionally, due to delays in Year 13 external examinations for one of its member countries (Fiji), USP will be forced to begin Semester One later. This means more than 3000 provisional students will have to wait for the university to begin in late March instead of the usual mid-February start. To keep these potential students engaged for close to two months, USP initiated an online orientation programme called "Semester Zero." The aim of the programme is to introduce these potential new students to USP using a Moodle platform instead of a traditional F2F orientation program, while at the same time incorporating basic numeracy, literacy, and digital skills necessary for new students. This paper shares the planning, designing, and feedback from students about this program. Semester Zero employs technology and innovations that have a low carbon footprint

Artificial intelligence and cardiac surgery during COVID-19 era

The coronavirus disease 2019 (COVID-19) pandemic has increased the burden on hospital staff world-wide. Through the redistribution of scarce resources to these high-priority cases, the cardiac sector has fallen behind. In efforts to reduce transmission, reduction in direct patient-physician contact has led to a backlog of cardiac cases. However, this accumulation of postponed or cancelled nonurgent cardiac care seems to be resolvable with the assistance of technology. From telemedicine to artificial intelligence (AI), technology has transformed healthcare systems nationwide. Telemedicine enables patient monitoring from a distance, while AI unveils a whole new realm of possibilities in clinical practice, examples include: traditional systems replacement with more efficient and accurate processing machines; automation of clerical process; and triage assistance through risk predictions. These possibilities are driven by deep and machine learning. The two subsets of AI are explored and limitations regarding "big data" are discussed. The aims of this review are to explore AI: the advancements in methodology; current integration in cardiac surgery or other clinical scenarios; and potential future roles, which are innately nearing as the COVID-19 era urges alternative approaches for care

Interdigitating Dendritic Cell Sarcoma of the Small Intestine Presenting as Spontaneous Hemoperitoneum – A Rare Case Report

Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare neoplasm arising from the antigen-presenting cells of the immune system. It usually involves the lymph nodes, and extranodal sites are rarely affected. Here, we report a first known case of spontaneous hemoperitoneum caused by the rupture of IDCS of the small bowel. A 61-year-old male presented with complaints of abdominal pain and fever for 3 days and breathlessness for 1 day. Ultrasound abdomen revealed a 15 cm × 7 cm heterogeneous collection with thick septations in the periumbilical region. Diagnostic peritoneal lavage revealed hemoperitoneum and gangrenous bowel. Emergency laprotomy was done and it revealed a friable mass arising from the ileum. Resection of 2 ft of the ileum and double-barrel ileostomy was done. Immunohistochemical analysis revealed a positivity of S100 and leukocyte common antigen). A diagnosis of IDCS was made. The patient had an uneventful postoperative recovery and planned for postoperative chemotherapy

Survival Outcomes and Prognostic Factors in Oral Squamous Cell Carcinoma with Locoregional Recurrence: A Retrospective Analysis

Introduction: Recurrence is known to occur in approximately 25% to 45% of patients treated for oral cancer. It is the most common cause of treatment failure in oral squamous cell carcinoma (OSCC), which adversely affects survival. Although recurrences in the oral cavity may be detected early, survival rates remain low. Aim: To identify the survival outcomes and prognostic factors in OSCC with locoregional recurrence. Materials and Methods: This retrospective study was conducted at the Malabar Cancer Centre between November 2020 to March 2021, analysing patients who were treated with curative intent between January 1997 and December 2017. It included 118 patients with OSCC who experienced recurrence-local, regional, or both-after curative treatment. Demographic variables, clinical variables, and follow-up details were analysed. Characteristics of the primary tumour, including nodal metastasis, stage, Extranodal Extension (ENE), Perineural Invasion (PNI), the extent of treatment, adjuvant therapy, and days to recurrence, were recorded. For the recurrent tumour, site, time to recurrence, and type of treatment received were noted additionally. Overall Survival (OS) was defined from the date of initial diagnosis, while the date of recurrence was determined by pathological confirmation. Statistical analysis was performed using SPSS software, version 20. All significant variables (p<0.05) were then tested in a multivariate analysis using Cox regression methods. Disease-specific survival (DSS) and OS were analysed using the Kaplan-Meier method. Results: A total of 146 patients with OSCC (15.01%) experienced a recurrence-local, regional, or both-upon analysis of 973 OSCC patients who underwent primary curative intent surgery. One hundred eighteen patients were included in the final analysis. Salvage surgery was performed on 65 (55.08%) patients. Thirty-eight patients (32.3%) who presented with early-stage disease initially developed a recurrence, whereas recurrences were more common among patients with advanced-stage disease, accounting for 80 (67.7%) cases. The median age of patients with recurrence was 60 years, with a median follow-up period of 46 months. The median OS time for patients with recurrence was 34 months ranging from 26.343 to 42.457 months. Univariate analysis revealed that nodal stage, salvage surgery, and time to recurrence were significant factors affecting OS. On multivariate analysis, salvage surgery and time to recurrence remained significant factors impacting survival. Conclusion: Salvage surgery and time to recurrence were identified as significant prognostic factors affecting survival outcomes in patients with OSCC experiencing locoregional recurrence. Salvage surgery significantly improves survival in oral cancer, where recurrence is usually detected more easily unlike other subsites. Patients with late recurrences demonstrated better survival outcomes. Tumours that recur early indicated poor oncological outcomes, suggesting an aggressive nature. Tumor biology is essential in guiding treatment options in recurrent settings
