Enhancing children's awareness of sexual abuse in Pakistan with video literacy interventional cartoons.

In presence of violent extremism, children in Pakistan are at high risk for child sexual abuse (CSA), especially after the COVID-19 pandemic. Effective approaches for preventing CSA include enhancing resilience resources in violence-affected societies. Previous research suggests that video-based curricula effectively enhances learning in primary schoolchildren. We pilot tested a video literacy program to build awareness in children, creating a 'personal safety and space bubble' as an educational approach for prevention of sexual abuse with an experimental 6 weeks long pre- and post-test design. We conducted qualitative interviews with students, teachers, and parents and identified themes using frequency analyses. Results showed a 96.7% increase in awareness about 'personal safety and space bubble'. The pilot study is valuable for public health researchers and policy makers seeking to curtail sexual abuse in extreme violence affected Pakistan. Primary schools can use such interventional cartoons to enhance awareness about child sexual abuse.

Efficacy of an anti-bullying video literacy program in Pakistani primary school children.

With a scarcity of research looking at violent and extremist tendencies in primary school children in Pakistan, this study aimed to look at the effects of emotional resilience education through the means of cartoon-based learning. Children have a limited attention span and research on video/cartoon-based literacy projects has indicated greater efficacy with more retention and engagement. The cartoon based on the theme of anti-bullying was used in a 6-week intervention program in an experimental design setup with 120 experimental and 40 control group students recruited from the Islamabad/Rawalpindi area (ages 9-11). The behaviours and awareness about the concepts of physical and verbal bullying, coercion and damaging others' property, as well as qualitative information about the cartoon themes were assessed before and after the program for pre- and post-test comparison. The cartoon was accompanied with teaching aids, worksheets and activity-based learning. The results indicated that only 3.3% students were aware about bullying and its various types to begin with and after intervention 98.7% understood the concept clearly. Before the intervention, 65.8% students didn't understand that they were bullies - after the intervention it reduced to 22.5% who thought they were not bullies. Effectiveness of the results from this video literacy program will enable development of more emotional resilience education courses in the curriculum to create a more resilient society in the long run and curb bullying in schools.

Prognostic Impact of Red Cell Distribution Width on the Development of Contrast-Induced Nephropathy, Major Adverse Cardiac Events, and Mortality in Coronary Artery Disease Patients Undergoing Percutaneous Coronary Intervention.

Red cell distribution width (RDW) serves as an independent predictor towards the prognosis of coronary artery disease (CAD) in patients undergoing percutaneous coronary intervention (PCI). A systematic search of databases such as PubMed, Embase, Web of Science, and Cochrane library was performed on October 10th, 2019, to elaborate the relationship between RDW and in hospital and long term follow up, all-cause and cardiovascular mortality, major adverse cardiac events (MACE) and development of contrast-induced nephropathy (CIN) in patients with CAD undergoing PCI. Twenty-one studies qualified this strict selection criterion (number of patients = 56,425): one study was prospective, and the rest were retrospective cohorts. Our analysis showed that patients undergoing PCI with high RDW had a significantly higher risk of in-hospital all-cause mortality (OR 2.41), long-term all-cause mortality (OR 2.44), cardiac mortality (OR 2.65), MACE (OR: 2.16), and odds of developing CIN (OR: 1.42) when compared to the patients with low RDW. Therefore, incorporating RDW in the predictive models for the development of CIN, MACE, and mortality can help in triage to improve the outcomes in coronary artery disease patients who undergo PCI.

Pheochromocytoma: An Incidental Finding in an Asymptomatic Older Adult With Renal Oncocytoma.

A high index of suspicion for pheochromocytoma is necessary during the workup of secondary hypertension as untreated pheochromocytoma may lead to significant morbidity and mortality, especially in patients who require any surgical treatment.

Role and mechanism of autophagy-regulating factors in tumorigenesis and drug resistance.

A hallmark feature of tumorigenesis is uncontrolled cell division. Autophagy is regulated by more than 30 genes and it is one of several mechanisms by which cells maintain homeostasis. Autophagy promotes cancer progression and drug resistance. Several genes play important roles in autophagy-induced tumorigenesis and drug resistance including Beclin-1, MIF, HMGB1, p53, PTEN, p62, RAC3, SRC3, NF-2, MEG3, LAPTM4B, mTOR, BRAF and c-MYC. These genes alter cell growth, cellular microenvironment and cell division. Mechanisms involved in tumorigenesis and drug resistance include microdeletions, genetic mutations, loss of heterozygosity, hypermethylation, microsatellite instability and translational modifications at a molecular level. Disrupted or altered autophagy has been reported in hematological malignancies like lymphoma, leukemia and myeloma as well as multiple solid organ tumors like colorectal, hepatocellular, gall bladder, pancreatic, gastric and cholangiocarcinoma among many other malignancies. In addition, defects in autophagy also play a role in drug resistance in cancers like osteosarcoma, ovarian and lung carcinomas following treatment with drugs such as doxorubicin, paclitaxel, cisplatin, gemcitabine and etoposide. Therapeutic approaches that modulate autophagy are a novel future direction for cancer drug development that may help to prevent issues with disease progression and overcome drug resistance.

Fundamentals of Light Chain Cardiac Amyloidosis: A Focused Review.

The estimated prevalence of AL CA in the US is approximately 8-12 cases per million. Almost 30-50% diagnosed cases of AL amyloid in the US have multisystem involvement, including cardiac involvement. Even with the availability of advanced diagnostic testing and novel therapies, prognosis remains poor. It is overlooked as a cause of heart failure with preserved ejection fraction leading to a delay in diagnosis when management options are limited and associated with poor survival outcomes. Therefore, the education of physicians is needed to ensure that it would be highly considered as a differential diagnosis. The purpose of this manuscript is to review the advances in the diagnosis and management of cardiac amyloidosis with the aim of educating colleagues who provide care in the primary care setting. We have summarized the pathogenesis of amyloidosis, its association with plasma cell dyscrasias, novel diagnostic and surveillance approaches including echocardiography, cardiovascular magnetic resonance imaging, histopathologic techniques, systemic biomarkers, and advanced treatment approaches including supportive symptomatic management and standard of care chemotherapy targeting the amyloid deposits. Given the overall poor prognosis of amyloidosis, we have also discussed the role of palliative and hospice care.

Investigational Monoclonal Antibodies in the Treatment of Multiple Myeloma: A Systematic Review of Agents under Clinical Development.

BACKGROUND: Immunotherapy for multiple myeloma (MM) has been the focus in recent years due to its myeloma-specific immune responses. We reviewed the literature on non-Food and Drug Administration (FDA) approved monoclonal antibodies (mAbs) to highlight future perspectives. We searched PubMed, EMBASE, Web of Science, Cochrane Library and ClinicalTrials.gov to include phase I/II clinical trials. Data from 39 studies (1906 patients) were included. Of all the agents, Isatuximab (Isa, anti-CD38) and F50067 (anti-CXCR4) were the only mAbs to produce encouraging results as monotherapy with overall response rates (ORRs) of 66.7% and 32% respectively. Isa showed activity when used in combination with lenalidomide (Len) and dexamethasone (Dex), producing a clinical benefit rate (CBR) of 83%. Additionally, Isa used in combination with pomalidomide (Pom) and Dex resulted in a CBR of 73%. Indatuximab Ravtansine (anti-CD138 antibody-drug conjugate) produced an ORR of 78% and 79% when used in combination with Len-Dex and Pom-Dex, respectively. CONCLUSIONS: Combination therapy using mAbs such as indatuximab, pembrolizumab, lorvotuzumab, siltuximab or dacetuzumab with chemotherapy agents produced better outcomes as compared to monotherapies. Further clinical trials investigating mAbs targeting CD38 used in combination therapy are warranted.

Future of Personalized Therapy Targeting Aberrant Signaling Pathways in Multiple Myeloma.

Multiple myeloma (MM) is a genetically complex disease. Identification of mutations and aberrant signaling pathways that contribute to the progression of MM and drug resistance has potential to lead to specific targets and personalized treatment. Aberrant signal pathways include RAS pathway activation due to RAS or BRAF mutations (targeted by vemurafenib alone or combined with cobimetinib), BCL-2 overexpression in t(11:14) (targeted by venetoclax), JAK2 pathway activation (targeted by ruxolitinib), NF-κB pathway activation (treated with DANFIN combined with bortezomib), MDM2 overexpression, and PI3K/mTOR pathway activation (targeted by BEZ235). Cyclin D1 (CCND1) and MYC are also emerging as key potential targets. In addition, histone deacetylase inhibitors are already in use for the treatment of MM in combination therapy, and targeted inhibition of FGFR3 (AZD4547) is effective in myeloma cells with t(4;14) translocation. Bromodomain and extra terminal (BET) protein antagonists decrease the expression of MYC and have displayed promising antimyeloma activity. A better understanding of the alterations in signaling pathways that promote MM progression will further inform the development of precision therapy for patients.

Pomalidomide-Based Regimens for Treatment of Relapsed and Relapsed/Refractory Multiple Myeloma: Systematic Review and Meta-analysis of Phase 2 and 3 Clinical Trials.

INTRODUCTION: Pomalidomide (Pom) has demonstrated synergistic antiproliferative activity in combination regimens as a result of its distinct anticancer, antiangiogenic, and immunomodulatory effects. This review aimed to compare outcome measures of different Pom regimens for relapsed/refractory multiple myeloma. METHODS: A comprehensive literature search identified a total of 1374 studies. Thirty-five studies assessing 4623 subjects met the inclusion criteria: phase 2/3 trial, ≥ 2 prior lines of therapy, and clearly documented efficacy outcomes like overall response rate (ORR), overall survival, and progression-free survival. Statistical analyses for meta-analysis was performed by CMA version 3 and Cochrane Q statistics (P < .05 considered significant, I2 index for heterogeneity). A random effects model was used if there was significant heterogeneity (P ≥ .05 over I2 ≥ 50%). RESULTS: Pooled analysis showed ORR 47.1% across all Pom-based (2- and 3-drug) regimens. Stratified analysis for efficacy outcomes (pooled ORR [%] and mean progression-free survival [months]) are reported. With doublet regimen, Pom with low-dose dexamethasone (LoDex) was the most common regimen (35.7%, 6.1 months), and overall survival was 14.37 months. With triplet regimens, pooled ORR was 61.9% (I2 = 87.3%). These included bortezomib + Pom + LoDex (83.5%, 15.7 months), carfilzomib-Pom + LoDex (77.1%, 15.3 months), Pom + LoDex-bendamustine (74.2%), Pom-dexamethasone-daratumumab (64.5%), Pom + LoDex-cyclophosphamide (59.4%, 9.5 months), and Pom + LoDex-doxorubicin (32%). Leading adverse events were myelosuppression, with mean incidences of grade 3 or higher neutropenia, anemia, and thrombocytopenia of 47.6%, 26.5%, and 20.8%, respectively. Mean incidence of grade 3 or higher nonhematologic adverse events were infections 29.1%, pneumonia 13.8%, and fatigue 10%. CONCLUSION: Three-drug Pom regimens yielded double the response rates compared to Pom + LoDex (pooled ORR, 61.9% vs. 35.7%), with bortezomib + Pom + LoDex and carfilzomib-Pom + LoDex demonstrating better outcomes than other regimens.
