Death-associated protein 3 in cancer-discrepant roles of DAP3 in tumours and molecular mechanisms

Cancer, ranks as the secondary cause of death, is a group of diseases that are characterized by uncontrolled tumor growth and distant metastasis, leading to increased mortality year-on-year. To date, targeted therapy to intercept the aberrant proliferation and invasion is crucial for clinical anticancer treatment, however, mutant expression of target genes often leads to drug resistance. Therefore, it is essential to identify more molecules that can be targeted to facilitate combined therapy. Previous studies showed that death associated protein 3 (DAP3) exerts a pivotal role in regulating apoptosis signaling of tumors, meanwhile, aberrant DAP3 expression is associated with the tumorigenesis and disease progression of various cancers. This review provides an overview of the molecule structure of DAP3 and the discrepant roles played by DAP3 in various types of tumors. Considering the molecular mechanism of DAP3-regulated cancer development, new potential treatment strategies might be developed in the future.

Early detection of self-breast examination using smartphone breast application

INTRODUCTION

Breast self-examination (BSE) is a screening method that can help empower, raise awareness, and detect breast abnormalities in women. The use of smartphone applications for breast cancer early detection is able to overcome some of these barriers. This study aimed to conduct a systematic review to assess the effectiveness of the effect of using smartphone application-based technology on breast cancer.

METHODS

Google Scholar, PubMed, Proquest, and ScienceDirect were searched for "breast self-examination" and "smartphone application" literature. This literature's study designs were quasi-experimental, prospective cohort, qualitative, and systematic review. The study contained five unique research projects with 828 varied participants.

RESULTS

The use of smartphones was seen to have advantages in terms of increased knowledge, perceived vulnerability, barriers to breast self-examination (BSE), self-efficacy, health motivation, and BSE practices.

CONCLUSIONS

The utilization of smartphone apps related to BSE is shown through the availability, accessibility, and focus of information and is in line with the Health Belief Model (HBM).

Early detection of neurodevelopmental disorders in paediatric primary care: A scoping review

BACKGROUND

Earlier detection of children at risk for neurodevelopmental disorders is critical and has longstanding repercussions if not addressed early enough.

OBJECTIVES

To explore the supporting or facilitating characteristics of paediatric primary care models of care for early detection in infants and toddlers at risk for neurodevelopmental disorders, identify practitioners involved, and describe how they align with occupational therapy's scope of practice.

METHODS

A scoping review following the Joanna Briggs Institute framework was used. PubMed Central, Cumulative Index to Nursing & Allied Health Literature, and Scopus databases were searched. The search was conducted between January and February 2022. Inclusion criteria were: children aged 0-3 years old; neurodevelopmental disorders including cerebral palsy (CP) and autism spectrum disorder (ASD); models of care used in the paediatric primary care setting and addressing concepts of timing and plasticity; peer-reviewed literature written in English; published between 2010 and 2022. Study protocol registered at https://doi.org/10.17605/OSF.IO/MD4K5.

RESULTS

We identified 1,434 publications, yielding 22 studies that met inclusion criteria. Models of care characteristics included the use of technology, education to parents and staff, funding to utilize innovative models of care, assessment variability, organizational management changes, increased visit length, earlier timeline for neurodevelopmental screening, and collaboration with current office staff or nonphysician practitioners. The top 4 providers were paediatricians, general or family practitioners, nurse/nurse practitioners, and office staff. All studies aligned with occupational therapy health promotion scope of practice and intervention approach yet did not include occupational therapy within the paediatric primary care setting.

CONCLUSIONS

No studies included occupational therapy as a healthcare provider that could be used within the paediatric primary care setting. However, all studies demonstrated models of care facilitating characteristics aligning with occupational therapy practice. Models of care facilitating characteristics identified interdisciplinary staff as a major contributor, which can include occupational therapy, to improve early detection within paediatric primary care.

Cervical Cancer Prevention on Instagram: Content and Social Interaction Analysis of Brazilian Accounts

OBJECTIVE

The aim of the present study was to analyse the content of posts on Instagram about cervical cancer.

METHODS

It was conducted a qualitative analysis using the 50 most popular publicly available Portuguese-language Instagram posts, containing the hashtags #cervicalcancer, #papsmear, #hpv, #papillomavirus, and #hpvvac-cine, during the Brazilian national cervical cancer prevention campaign in March 2018.

RESULTS

Posts recruited using #cervicalcancer provided 60% of posts with contents related to secondary prevention; the #papsmear provided 46% of posts with irrelevant contents; the #hpv and #papillomavirus provided 50% and 64% of posts with informative content, respectively; and the #hpvvaccine provided 58% of posts with content related to primary prevention. The posts that received the highest number of likes were those from the hashtags #hpv and #papillomavirus with 151.33 and 78.00 likes/post, respectively. The majority of posts presented less than 05 comments/post, except for the #hpv, which had 64.76 comments/post. According to the users' profiles, the majority of the posts, regardless of the hashtag used, were made by health professionals.

CONCLUSION

The focus of Instagram posts about cervical cancer is on secondary prevention, which can contribute to the promotion of health behaviours not directed to aspects of primary prevention of the disease.

Human papillomavirus prevalence and risk factors among HIV-negative and HIV-positive women residing in rural Eastern Cape, South Africa

OBJECTIVES

To investigate the prevalence of high-risk (HR) human papillomavirus (HPV) and factors associated with HR-HPV infection among women from rural Eastern Cape, South Africa.

METHODS

HPV prevalence was determined by Hybrid Capture 2 assay in cervical specimens from 417 women aged ≥30 years (median 46 years) recruited from the community health clinic in the Eastern Cape.

RESULTS

HR-HPV prevalence was 28.5% (119/417), and HIV-positive women had significantly higher HR-HPV prevalence than HIV-negative women (40.6%, 63/155 vs 21.4%, 56/262, respectively; p = 0.001). HIV-positive status (odds ratio (OR) 2.52, 95% confidence interval (CI) 1.63-3.90), having ≥3 lifetime sexual partners (OR 2.12, 95% CI 1.16-3.89), having ≥1 sexual partner in the last month (OR 1.89, 95% CI 1.21-2.92), ≥4 times frequency of vaginal sex in the past 1 month (OR 2.40, 95% CI 1.32-4.35), and having a vaginal discharge currently/in the previous week (OR 2.13, 95% CI 1.18-3.85) increased the risk of HR-HPV infection. In the multivariate analysis, HIV positivity remained strongly associated with HR-HPV infection (OR 1.94, 95% CI 1.17-3.22).

CONCLUSIONS

Risk factors related to sexual behaviors play a significant role in HR-HPV infection in this population. This report will inform health policymakers on HPV prevalence and contribute to discussions on the use of HPV testing as the primary cervical cancer screening test in South Africa.

Must pilots permanently quit flying career after treatment for colorectal cancer? - Medical waiver for Air Force pilots with colorectal cancer: Three case reports

BACKGROUND

Colorectal cancer (CRC) could seriously threaten the physical and mental health of pilots. Shall they end their flying after treatment of CRC? With this study, we investigated the possibility of a gradual medical waiver for such pilots to fly aircrafts again after treatment of CRC.

CASE SUMMARY

We analyzed the medical waiver and clinical data of 3 pilots with CRC, who had accepted the treatment at the Department of General Surgery, Air Force Medical Center (formerly, Air Force General Hospital) between 2013 and 2018. All 3 cases underwent a series of comprehensive treatment courses, including radical resection of CRC, sequential radiotherapy, and chemotherapy. The follow-up results were satisfactory. After passing through the high-risk period of recurrence and metastasis of CRC, they all were given a medical waiver for flying again. Medical observation showed that their flying operations were safe.

CONCLUSION

The CRC treatment shall follow the guidelines for diagnosis and treatment and should simultaneously protect the combating capabilities of pilots as much as possible. It is safe for pilots with CRC, who are continuously monitored under medical observation after passing through the high-risk period of recurrence and metastasis, to undertake military flight missions again.
