Imaging in Carcinoma Cervix and Revised 2018 FIGO Staging System: Implications in Radiology Reporting.

Indian J Radiol Imaging 2021 Jul 7;31(3):623-634. Epub 2021 Sep 7.

Department of Obstetrics & Gynaecology, All India Institute of Medical Sciences, New Delhi, India.

The International Federation of Gynecology and Obstetrics (FIGO) staging system of carcinoma cervix saw a radical change in 2018 with the inclusion of cross-sectional imaging tools for the assessment of disease extent and staging. One of the major revisions is the inclusion of lymph node status, detected either on imaging or pathological evaluation, in the staging system. The changes were based on long-term patient follow-up and survival rates reported in literature. Thus, it becomes imperative for a radiologist to be well versed with the recent staging system, its limitations, and implications on the patient management.

Objectives: To summarize the evidence on prevention of early childhood caries (ECC) by professionally or self-applied topical fluorides using network meta-analysis.

Data: Randomized-controlled trials with minimum 1-year follow-up assessing caries-preventive effect among children younger than six years.

Sources: Eight electronic databases and grey literature.

Study Selection: After screening and data extraction, risk of bias assessment using Cochrane risk of bias tool 2.0 was done. Twenty-four trials were included, among which 17 were assessed as "high risk" and remaining as "low risk". Fifteen studies evaluated professionally-applied, and the other nine used self-applied topical fluorides. Ten studies on professionally-applied fluorides reporting the net caries increment (dmfs increment) at 2-years follow-up were included in Network meta-analysis (NMA). NMA and ranking the interventions were conducted using a frequentist random-effects approach and surface under the cumulative ranking command, followed by assessing the certainty of evidence using an extension of GRADE approach with CINeMA framework. Among the eight included interventions of professionally-applied fluorides, only two, i.e., 3-monthly 0.9% difluorosilane (DFS) and 6-monthly 5% sodium fluoride varnish were effective in preventing ECC compared to control with 3-monthly DFS application ranking higher than 6-monthly sodium fluoride varnish application.

Conclusion: Among all the professionally-applied topical fluoride interventions reviewed, very low to moderate evidence was found with 0.9% DFS application at 3-monthly intervals, which was ranked highest in prevention of ECC. Among the included studies on self-applied topical fluorides, the evidence was inconclusive due to heterogeneity among studies.

Clinical Significance: The 0.9% DFS varnish applied every 3 months is most effective for preventing early childhood caries. The review recommends that good quality studies be conducted in future, comparing two or more interventions for both self- as well as professionally-applied topical fluoride agents with adequate follow-up.

Educators' online teaching self-efficacy and compassion fatigue during the COVID-19 pandemic: The dual roles of "connect".

Sch Psychol 2021 Nov;36(6):504-515

Graduate School of Education, University of California, Berkeley.

Guided by the job demands-resources model and social-cognitive theory, we examined how educator perceived school connectedness and their attempts to connect with school members (i.e., administrators, staff, students, and families) concurrently and interactively influenced educators' compassion fatigue and online teaching self-efficacy during distance learning in the Coronavirus disease (COVID-19) pandemic. Participants were 321 educators in a large, urban school district in northern California. Results of linear regression modeling suggested that educators with longer years of working in education and White educators reported higher levels of compassion fatigue than their counterparts. White educators also reported a lower level of online teaching self-efficacy than their counterparts. With the control of educators' gender, race/ethnicity, and years of teaching in education, educators' self-reported school connectedness is negatively associated with compassion fatigue. Educators' attempts to connect with students not only positively associated with compassion fatigue but also intensified the negative association between school connectedness and compassion fatigue. Moreover, educators' school connectedness and attempts to connect with administrators and staff both positively associated with online teaching self-efficacy. Also, educators' attempts to connect with families mitigated the positive association between school connectedness and online teaching self-efficacy. The findings highlight the importance of promoting educators' school connectedness in improving educators' occupational wellbeing. It also highlights that educators' school connectedness and their attempts to connect with certain group of school members mutually and interactively influence educators' compassion fatigue and online teaching self-efficacy.

Evaluation of Non-infectious Pulmonary Complications in Hematological Malignancies on MDCT: Decoding Imaging Markers.

Indian J Hematol Blood Transfus 2021 Oct 5;37(4):669-674. Epub 2021 Apr 5.

Department of Hematology, All India Institute of Medical Sciences, New Delhi, India.

Patients with hematological malignancies are at risk of developing of various infectious and non-infectious pulmonary complications. Common non-infectious pulmonary complications include pulmonary edema, leukostasis, diffuse alveolar haemorrhage (DAH) and differentiation syndrome. The overlapping imaging features pose diagnostic dilemma. We retrospectively analysed the CT findings in identifying differentiating imaging markers and developing an algorithm. 46 diagnosed patients of non-infectious pulmonary complications who underwent CT chest between February 2017 to March 2020 were included. The CT findings were recorded as parenchymal (GGO, consolidation, septal thickening, peribronchovascular interstitial thickening, and nodules), pleural effusion, and mediastinal lymphadenopathy. We categorized non-infectious pulmonary complications as: differentiation syndrome (Group1, n = 6), DAH (Group 2, n = 8), leukostasis (Group 3, n = 14),leukemic infiltrate (Group 4, n = 5), and pulmonary edema(Group 5, n = 13). Chi-square or Fisher exact test were used with value 0.05 as statistically significant.Absence of diffuse GGO in Group 4, interlobular septal thickening in Group 2 and Group 3, nodules in Group 5, and peribronchovascular interstitial thickening in Group 2 were statistically significant. Presence of interlobular septal thickening in Group 5, nodules in Group 4, and peribronchovascular interstitial thickening in Group 5 were statistically significant. Based on the results, an algorithm was developed which may suggest a possible diagnosis in an appropriate clinical scenario.
