Improve the cervical cancer prevention behaviors through mobile-based educational intervention based on I-CHANGE model: study protocol for a randomized controlled trial
Get PDFBackground:
Applications of mobile technologies (mHealth) have the potential to reduce health inequalities, give patients more control over their health, and improve health care’s cost-effectiveness. The widespread use of mobile phones offers us a new way to prevent cervical cancer. The objective of the study was to design and develop a mobile phone application (app) that aims to conduct a behavioral intervention for women and to evaluate the efficacy of the app-based intervention.
Methods:
This study involves 5 phases. In the first phase, understanding women’s perspectives will be identified using a qualitative approach based on the I-Change model. In phase 2, the results from the qualitative approach and requirement prioritization through providing experts’ perspectives will be done. The main outputs of this phase will be resulted in prioritizing the main measurable effective variables of the I-Change model. Phase 3 will be processed for the development and psychometric of an assessment tool regarding selected constructs. In phase 4, the App framework and content development will be performed. In phase 5, a three-armed, parallel-design randomized controlled trial will be conducted on women. Two hundred ten women will be randomly assigned to three groups including two intervention groups and one control group. The intervention groups included the following: (1) a mobile application and (2) a digital book. The data will be evaluated using tools designed and constructed in phase 3 of the study at baseline in 3-month follow-up assessments. The impact of the two interventions on cervical cancer prevention behaviors through mobile-based educational intervention will then be evaluated.
Discussion:
A theory-based health education program using a mobile app to improve cervical cancer-preventive behaviors will be implemented for the first time in Iran. With an effective health mobile-based educational design, it is very important to determine whether Iranian women will be motivated to adhere to preventive behavior related to CC
Prevalence of blood-borne viral and sexually transmitted infections among homeless people in Berlin
Get PDFBackground:
Risk factors associated with precarious living conditions make people experiencing homelessness (PEH) also highly vulnerable for blood-borne viral and sexually transmitted infections (BBVSTI) and tuberculosis (TB). The number of PEH in Germany is rising, yet little data is available on the infectious burden among this population. A pilot study assessed the prevalence of BBVSTI, TB, behaviours and access to medical services among PEH.
Methods:
We recruited PEH from April-June 2021 in five low-threshold medical services in Berlin. Behavioural data was collected via questionnaire-based interviews. Serological/molecular testing from venous blood samples was performed for Hepatitis B (HBV), Hepatitis C (HCV), HIV, syphilis and TB and from urine for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT).
Results:
Of 216 participants, 88% (191/216) were male and 73% (158/215) were born abroad. Mean age was 41 years (range 19-68). No health insurance was reported by 57% (123/216) and previous incarceration by 71% (153/214). Of all, 53% (114/216) injected drugs in the last 30 days, and 41% (89/216) reported unprotected sex in the last 12 months. Prevalence of active HBV was 1.9% (4/212), of active HCV 15.9% (34/213), and of HIV 2.8% (6/213). No active TB was diagnosed, while 14.4% (31/216) tested positive for latent TB infection. Active syphilis was found in 1.4% (3/212), NG in 2.0% (4/197), CT in 3.0% (6/197), and serological evidence of HBV vaccination in 26% (56/212). While 44% (96/216) of participants were ever tested for HCV, 71% (36/51) of those with HCV antibodies knew about their infection, 36% (13/36) of them reported previous/current treatment.
Conclusions:
Burden of HCV and HIV was high among PEH in Berlin, and risk behaviours were frequently reported. There is a need to improve access to regular health care, accompanied by low-threshold prevention offers in cooperation with drug and homeless services. A nationwide expansion of the study is planned
RefineNet‐based 2D and 3D automatic segmentations for clinical target volume and organs at risks for patients with cervical cancer in postoperative radiotherapy
Get PDFPurpose:
An accurate and reliable target volume delineation is critical for the safe and successful radiotherapy. The purpose of this study is to develop new 2D and 3D automatic segmentation models based on RefineNet for clinical target volume (CTV) and organs at risk (OARs) for postoperative cervical cancer based on computed tomography (CT) images.
Methods:
A 2D RefineNet and 3D RefineNetPlus3D were adapted and built to automatically segment CTVs and OARs on a total of 44 222 CT slices of 313 patients with stage I–III cervical cancer. Fully convolutional networks (FCNs), U‐Net, context encoder network (CE‐Net), UNet3D, and ResUNet3D were also trained and tested with randomly divided training and validation sets, respectively. The performances of these automatic segmentation models were evaluated by Dice similarity coefficient (DSC), Jaccard similarity coefficient, and average symmetric surface distance when comparing them with manual segmentations with the test data.
Results:
The DSC for RefineNet, FCN, U‐Net, CE‐Net, UNet3D, ResUNet3D, and RefineNet3D were 0.82, 0.80, 0.82, 0.81, 0.80, 0.81, and 0.82 with a mean contouring time of 3.2, 3.4, 8.2, 3.9, 9.8, 11.4, and 6.4 s, respectively. The generated RefineNetPlus3D demonstrated a good performance in the automatic segmentation of bladder, small intestine, rectum, right and left femoral heads with a DSC of 0.97, 0.95, 091, 0.98, and 0.98, respectively, with a mean computation time of 6.6 s.
Conclusions:
The newly adapted RefineNet and developed RefineNetPlus3D were promising automatic segmentation models with accurate and clinically acceptable CTV and OARs for cervical cancer patients in postoperative radiotherapy
STAT3 exerts pro-tumor and anti-autophagy roles in cervical cancer
No full textBackground:
STAT3 plays an important role in cervical cancer. LC3B, the most potential molecular biomarker of autophagy that may promote or inhibit cancer progression, can be downregulated by STAT3. However the role of STAT3 in the autophagy of cervical cancer remains unclear.
Purpose:
This study aimed to evaluate the relationship between STAT3 and LC3B in protein level, and verify whether STAT3 promotes proliferation, migration and plate colony formation by inhibiting autophagy of cervical cancer cells through bcl2-beclin1 axis.
Results:
STAT3 was overexpressed in cervical cancer tissues, and negatively correlated with the expression level of LC3B. STAT3 knockout or knockdown significantly increased the autophagy level and decreased proliferation, migration, plate colony formation and subcutaneous tumorigenesis of cervical cancer cells in vitro and in vivo. STAT3 is known to mediate autophagy through Bcl2-Beclin1 complex. Bcl2 was positively whereas Beclin1 negatively correlated with STAT3 expression, indicating that Bcl2-Beclin1 complex involved in this transition.
Conclusion:
STAT3 may upregulate the autophagy level of cervical cancer cells through the Bcl2-Beclin1 axis. This indicates that STAT3 may be an important prognostic and therapeutic target for cervical cancer
A qualitative inquiry into pregnant women’s perceptions of respectful maternity care during childbirth in Ibadan Metropolis, Nigeria
Get PDFWomen’s perceptions of respectful maternity care (RMC) are critical to its definition and measurement globally. We evaluated these in relation to globally defined RMC norms. We conducted a descriptive study involving eight focus group discussions with 50 pregnant women attending antenatal clinic at one primary and one secondary health facility each in the North-west and South-west local government areas of Ibadan Metropolis, Nigeria. One focus group each with primigravidae and multiparas were held per facility between 21 and 25 October 2019. Shakibazadeh et al’s 12 domains of RMC served as the thematic framework for data analysis. The women’s perceptions of RMC resonated well with seven of its domains, emphasising provider-client inter-personal relationships, preserving their dignity, effective communication, and non-abandonment of care, but with mixed perceptions for two domains. However, their perceptions deviated for four domains, namely maintaining privacy and confidentiality; ensuring continuous access to family support such as birth companions; obtaining informed consent; and respecting women’s choices about mobility during labour, food and fluid intake, and birth position. The physical environment was not mentioned as contributing to an experience of RMC. Whilst the perceptions of the Nigerian women studied about RMC were similar to those accepted internationally, there were significant deviations which may be related to cultural differences and societal disparities. Different interpretations of RMC may influence women’s demand for such care in different settings and challenge strategies for promoting a universal standard of care
Prognostic factors for post-recurrence survival among patients with locally advanced cervical cancer who underwent definitive concurrent chemoradiation
Get PDFBackground:
The prognostic factors affecting post-recurrence survival (PRS) in patients with locally advanced cervical cancer (LACC) who receive concurrent chemoradiation (CCRT) are not well established. This study aimed to assess the prognostic factors for PRS in patients with recurrent LACC who underwent CCRT as the primary treatment.
Materials and methods:
We retrospectively reviewed the medical records of patients with a first recurrence of cervical cancer (stage IB2–IVA), who were initially treated with CCRT and completed the planned radiotherapy from 2002 to 2018. Multivariate analysis of independent factors for PRS was performed with the Cox proportional-hazards model.
Results:
Of 1,658 patients with LACC primarily treated with CCRT, 424 (25.6%) had recurrence, with 142, 125, and 157 patients having locoregional, distant, and combined recurrence, respectively. Approximately 75% of recurrence cases were detected within 2 years after completed treatment, and 81.8% of cases demonstrated symptoms at recurrence diagnosis. The median PRS was 8.4 months, and the 1- and 5-year PRS rates were 36.0% and 5.3%, respectively. Multivariate analysis found that the recurrence-free interval (RFI) (p < 0.001), recurrence pattern (p < 0.001), white blood cell count (p < 0.001), and treatment at recurrence (p < 0.001) were independent prognostic factors for PRS.
Conclusion:
The prognosis of recurrent LACC initially treated with CCRT was notably poor. RFI, recurrence pattern, white blood cell count, and treatment at recurrence were independent prognostic factors for PRS
A Ugandan parenting programme to prevent gender-based violence: description and formative evaluation
Get PDFPurpose: To develop a culturally-sensitive intervention for the early prevention of gender-based violence (GBV) in Uganda. Methods: Programme design followed the 6SQuID model of intervention development and multi-sectorial advice. A formative evaluation was conducted in two communities with six groups and 138 participants. Findings: Four familial predictors of GBV were identified as potentially malleable: poor parent–child attachment, harsh parenting, inequitable gendered socialization and parental conflict. A community-based parenting programme was developed to address them. Its programme theory incorporates Attachment Theory, the concept that positive behavioural control develops emotional control, and Social Learning Theory. Its rationale, structure and content are presented using the TIDieR checklist. A formative evaluation showed the programme to be widely acceptable, culturally appropriate, and perceived to be effective, but also identified challenges. Conclusion: The careful development of this community-based parenting programme shows promise for the early prevention of GBV
Improving menstrual health literacy through life-skills programming in rural Ethiopia
Get PDFDespite its cultural and biological importance, limited knowledge about menstruation and cultural taboos in many contexts mean that menarche often brings fear and stigma. In Ethiopia, the context of this paper, lack of knowledge and the stigma around menstruation create challenges for adolescent girls related to menstrual hygiene management and their reproductive health more broadly. This paper uses a cluster-randomized controlled trial (cRCT), with 97 communities (kebeles) randomly assigned to treatment or control, to assess the impact of a gender-transformative life-skills intervention [Act With Her-Ethiopia (AWH-E)] on the menstrual health literacy of very young adolescent girls and boys (10–14) in two diverse regions of Ethiopia (South Gondar, Amhara and East Hararghe, Oromia). The evaluation employs a longitudinal mixed-methods design, with baseline data collected in late 2017/early 2018 and follow-up data collected in late 2019/early 2020. Quantitative surveys were undertaken with 2,492 very young adolescents and their primary caregivers, and complemented by qualitative interviews with 291 adolescents and their caregivers, as well as 96 key informants at community and district levels. Our quantitative findings highlight large and statistically significant improvements on norms around menstruation, knowledge about menstruation and biological function, and knowledge and behavior related to menstrual hygiene management, but with important differences by location and gender. Qualitative findings further unpack these gender and regional differences, highlighting the importance of adapting programming to the local context and, where possible, connecting to other health and gender initiatives. This analysis helps fill the evidence gap on “what works” to improve menstrual health literacy in rural low- and middle-income contexts
Phytochemical constituents and antiproliferative activities of essential oils from four varieties of malaysian zingiber officinale roscoe against human cervical cancer cell line
Get PDFThis study evaluates the volatile metabolic constituents and anticancer potential of essential oils distilled from the rhizomes of four Malaysian Zingiber officinale Roscoe (Zingiberaceae family) varieties (Bentong (BE), Cameron Highlands (CH), Sabah (SA), and Bara (BA)). The ginger essential oils were analyzed by gas chromatography coupled with quadrupole mass spectrometry (GC qMS). A total of 58 secondary compounds were tentatively identified, representing 82.6–87.4% of the total ion count. These metabolites comprise mainly of monoterpene hydrocarbons (19.7–25.5%), oxygenated monoterpenes (23.6–33.7%), sesquiterpene hydrocarbons (21.3–35.6%), oxygenated sesquiterpenes (1.5–3.9%), and other minor classes of compounds (0.7–2.7%). Principal component analysis (PCA) enabled differentiation of the analyzed ginger essential oils according to their varieties, with respect to their metabolites and relative quantities. The antiproliferative activity against the HeLa cervical cancer cell line was investigated via the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The oils were found to exhibit strong antiproliferative activities with IC50 values of 23.8, 35.3, 41.3, and 42.5 μg/mL for BA, BE, SA, and CH, respectively. These findings suggest that the differences among the secondary metabolites and their abundance in different varieties of Z. officinale essential oils appear to be related to their antiproliferative potential. The strong antiproliferative effects of these oils signified their potential in the prevention and chemotherapy of cervical carcinoma treatment
Development and validation of a nomogram for predicting pelvic lymph node metastasis and prognosis in patients with cervical cancer
Get PDFObjective:
Cervical cancer (CC) is one of the main causes of death among gynecological malignancies. Patients with CC with lymph node metastasis (LNM) have poor prognoses. We investigated the risk factors and prognosis of LNM in patients with CC patients using data from the SEER database.
Methods:
We collected the information of cervical cancer patients registered in SEER database from 2010 to 2015. The dataset was divided into a training set and a validation set at a 7:3 ratio. LASSO regression analysis was used to evaluate risk factors for LNM in patients with CC. Using the results, we established a nomogram prediction model. C-index, ROC curves, calibration curves, decision curve analysis, and clinical impact curves were used to evaluate the prediction performance of the model.
Results:
We included 14,356 patients with CC in the analysis. Among these, 3997 patients were diagnosed with LNM. A training set (10,050 cases) and a validation set (4306 cases) were used for the following analysis. We established nomogram LNM prediction models for the patients with T1-2-stage CC. The C-indices for the internal and external validations of the prediction models were 0.758 and 0.744, respectively. In addition, we established a prognostic nomogram for all CC patients with LNM, and the internal and external validation C-indices were 0.763 and 0.737.
Conclusion:
We constructed a quantitative and visual predictive nomogram that predicted prognosis of patients with LNM in CC to provide clinicians with a reference for diagnosis and treatment
