Qaqish A, Abdo N, Abbas MM, Saadeh N, Alkhateeb M, Msameh R, Tarawneh S, Al-Masri M. Awareness and knowledge of physicians and residents on the non-sexual routes of human papilloma virus (HPV) infection and their perspectives on anti-HPV vaccination in Jordan. PLoS One 2023; 18:e0291643. [PMID: 37819974 PMCID: PMC10566688 DOI: 10.1371/journal.pone.0291643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Accepted: 09/04/2023] [Indexed: 10/13/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Although penetrative sex is the most common route of HPV infection, there is strong evidence of non-sexual modes of transmission. As the first of its kind, this study aimed to investigate the knowledge and awareness of Jordanian physicians on such routes. METHODS A questionnaire was conducted among a national Jordanian sample of physicians from Jordanian health sectors. The survey included questions assessing participants' knowledge on HPV, non-sexual routes of infection and HPV vaccines. Physicians' attitudes towards HPV screening and vaccination were covered. Statistical analysis was carried out using SAS 9.4, ANOVA, post-hoc Tukey-Honest test and Kruskal-Wallis test. All significant differences were set at α = 0.05. RESULTS A total of 412 participants completed the survey. Physicians showed a huge deficit in knowledge on nonsexual routes of HPV transmission. They agreed that the most and least common routes of non-sexual transmission are skin to mucosa (64%) and contaminated water (15%), respectively. Females showed significantly better knowledge in all aspects of HPV transmission and vaccination (p<0.0001) and more positive attitudes towards HPV screening and vaccination compared to males (p = 0.03). Age group ≤ 25 and academic physicians demonstrated higher knowledge on HPV vaccines compared to their counterparts in non-academic places (p = 0.002). Specialty and experience seemed to have no impact on knowledge or attitudes of participants. Higher knowledge physicians had more positive attitude towards vaccination and screening compared to lower knowledge fellows (p<0.001). CONCLUSIONS The noteworthy findings of this study is the extremely low level of knowledge on non-sexual routes of HPV infection among Jordanian physicians. Increasing the level of awareness of physicians and healthcare workers on these routes and their association with cervical and other cancers through university curricula and other reliable sources is strongly recommended.

[PMID: 37664989 PMCID: PMC10476963 DOI: 10.7554/elife.86358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 07/28/2023] [Indexed: 09/05/2023] Open
Abstract
Background The COVID-19 pandemic led to reductions in cervical cancer screening and colposcopy. Therefore, in this mixed methods study we explored perceived pandemic-related practice changes to cervical cancer screenings in federally qualified health centers (FQHCs). Methods Between October 2021 and June 2022, we conducted a national web survey of clinicians (physicians and advanced practice providers) who performed cervical cancer screening in FQHCs in the United States during the post-acute phase of the COVID-19 pandemic, along with a sub-set of qualitative interviews via video conference, to examine perceived changes in cervical cancer screening practices during the pandemic. Results A total of 148 clinicians completed surveys; a subset (n=13) completed qualitative interviews. Most (86%) reported reduced cervical cancer screening early in the pandemic, and 28% reported continued reduction in services at the time of survey completion (October 2021- July 2022). Nearly half (45%) reported staff shortages impacting their ability to screen or track patients. Compared to clinicians in Obstetrics/Gynecology/Women's health, those in family medicine and other specialties more often reported reduced screening compared to pre-pandemic. Most (92%) felt that screening using HPV self-sampling would be very or somewhat helpful to address screening backlogs. Qualitative interviews highlighted the impacts of staff shortages and strategies for improvement. Conclusions Findings highlight that in late 2021 and early 2022, many clinicians in FQHCs reported reduced cervical cancer screening and of pandemic-related staffing shortages impacting screening and follow-up. If not addressed, reduced screenings among underserved populations could worsen cervical cancer disparities in the future. Funding This study was funded by the American Cancer Society, who had no role in the study's design, conduct, or reporting.

Good practices in perinatal bereavement care in public maternity hospitals in Southern Spain. Midwifery 2023; 124:103749. [PMID: 37271065 DOI: 10.1016/j.midw.2023.103749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 04/23/2023] [Accepted: 05/29/2023] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To assess the attitudes and care practices of midwives and nurses in the province of Granada in relation to death care and perinatal bereavement, to determine their degree of adaptation to international standards and to identify possible differences in personal factors among those who best adapt to international recommendations. DESIGN A local survey of 117 nurses and midwives from the five maternity hospitals in the province was conducted using the Lucina questionnaire developed to explore professionals' emotions, opinions, and knowledge during perinatal bereavement care. Adaptation of practices to international recommendations was assessed using the CiaoLapo Stillbirth Support (CLASS) checklist. Socio-demographic data were collected to establish their association with increased compliance with recommendations. FINDINGS The response rate was 75.4%, the majority were women (88.9%), with a mean age of 40.9 (SD=1.4) and 17.4 (SD= 10.58) years of work experience. Midwives were the most represented (67.5%) and reported having attended more cases of perinatal death (p = 0.010) and having more specific training (p<0.001.) Of these, 57.3% would recommend immediate delivery, 26.5% would recommend the use of pharmacological sedation during delivery and 47% would take the baby immediately if the parents expressed their wish not to watch them. On the other hand, only 58% would be in favour of taking photos for the creation of memories, 47% would bathe and dress the baby in all cases, and 33.3% would allow the company of other family members. The percentage that matched each recommendation on memory-making was 58%, 41.9% matched the recommendations on respect for the baby and parents, and 23% and 10.3% matched the appropriate delivery and follow-up options, respectively. The factors associated with 100% of the recommendations, according to the care sector, were being a woman, a midwife, having specific training and having personally experienced the situation. KEY CONCLUSIONS Although the levels of adaptation observed are more favourable than in other nearby contexts, serious deficiencies are identified in the province of Granada with respect to internationally agreed recommendations on perinatal bereavement care. More training and awareness-raising of midwives and nurses is needed, which also considers factors related to better compliance. IMPLICATION FOR PRACTICE This is the first study to quantify the degree of adaptation to international recommendations in Spain reported by midwives and nurses, as well as the individual factors associated with a higher level of compliance. Areas for improvement and explanatory variables of adaptation are identified, which allow support for possible training and awareness-raising programmes aimed at improving the quality of care provided to bereaved families.

Abstract
Breast cancer is prevalent and fatal in Korean American women (KAW) and KAW report low screening rates. This study examined the impact of patient-physician relationships on mammography use in KAW, focusing on patient-physician ethnic and gender concordance, distrust in health professionals, and accessibility to health care. Cross-sectional survey data were collected from 340 KAW in North Carolina, and logistic regression was conducted to identify factors associated with mammography use. Having a non-Korean physician, regular check-ups, and physician recommendations were positively associated with getting mammography. Neither gender concordance nor distrust in health professionals predicted adherence to breast cancer screening guidelines. The findings highlight the critical roles of routine health care practice and usual source of care in compliance with the screening guidelines in KAW. Additional research is warranted to explore breast cancer screening recommendation behaviors and patterns of Korean American physicians compared to non-Korean counterparts.

Integrated interventions and supporting activities to increase uptake of multiple cancer screenings: conceptual framework, determinants of implementation success, measurement challenges, and research priorities. Implement Sci Commun 2022; 3:105. [PMID: 36199098 PMCID: PMC9532830 DOI: 10.1186/s43058-022-00353-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 09/19/2022] [Indexed: 10/25/2022] Open
Abstract
BACKGROUND Screening for colorectal, breast, and cervical cancer has been shown to reduce mortality; however, not all men and women are screened in the USA. Further, there are disparities in screening uptake by people from racial and ethnic minority groups, people with low income, people who lack health insurance, and those who lack access to care. The Centers for Disease Control and Prevention funds two programs-the Colorectal Cancer Control Program and the National Breast and Cervical Cancer Early Detection Program-to help increase cancer screenings among groups that have been economically and socially marginalized. The goal of this manuscript is to describe how programs and their partners integrate evidence-based interventions (e.g., patient reminders) and supporting activities (e.g., practice facilitation to optimize electronic medical records) across colorectal, breast, and cervical cancer screenings, and we suggest research areas based on implementation science. METHODS We conducted an exploratory assessment using qualitative and quantitative data to describe implementation of integrated interventions and supporting activities for cancer screening. We conducted 10 site visits and follow-up telephone interviews with health systems and their partners to inform the integration processes. We developed a conceptual model to describe the integration processes and reviewed screening recommendations of the United States Preventive Services Task Force to illustrate challenges in integration. To identify factors important in program implementation, we asked program implementers to rank domains and constructs of the Consolidated Framework for Implementation Research. RESULTS Health systems integrated interventions for all screenings across single and multiple levels. Although potentially efficient, there were challenges due to differing eligibility of screenings by age, gender, frequency, and location of services. Program implementers ranked complexity, cost, implementation climate, and engagement of appropriate staff in implementation among the most important factors to success. CONCLUSION Integrating interventions and supporting activities to increase uptake of cancer screenings could be an effective and efficient approach, but we currently do not have the evidence to recommend widescale adoption. Detailed multilevel measures related to process, screening, and implementation outcomes, and cost are required to evaluate integrated programs. Systematic studies can help to ascertain the benefits of integrating interventions and supporting activities for multiple cancer screenings, and we suggest research areas that might address current gaps in the literature.

Abstract
OBJECTIVES To evaluate the association between cancer screening counselling provided by medical doctors to their patients and each doctor's own anthropometrics, lifestyle, cancer screening practices, and personal and family history of cancer. DESIGN Prospective cohort study. SETTING Substudy including physicians participating in a Spanish cohort study with open enrolment. PARTICIPANTS Among 22 800 participants in the cohort as of May 2018, there were 2371 physicians who had replied to the cohort baseline questionnaire, had an email account and were younger than 65 years (retirement age in Spain). From this subsample, 890 replied to an online questionnaire focused on their clinical practices related to the counselling provided to their patients and to their prescription practices of preventive medications. Their mean age was 51.7 (SD 9.4) years and 48% were women. OUTCOME MEASURES Frequency of counselling given to their patients on specific practices of breast, colorectal and prostate cancer screenings. RESULTS Counselling on cancer screening to their patients was provided by 65% of physicians in a scenario of colorectal cancer, 59% for prostate cancer and 58% for breast cancer. More frequent cancer screening counselling was associated with the specialties of family medicine (OR=9.4, 95% CI 5.1 to 17.1) and internal medicine (OR=2.9, 95% CI 1.5 to 5.7) as compared with other specialties. Recommending cancer screening was associated with more frequent counselling on smoking cessation (OR=3.7, 95% CI 2.6 to 5.4), having personally attended colorectal cancer screening (OR=2.2, 95% CI 1.1 to 4.7) and prescribing blood pressure medication more often than their colleagues (OR=2.1, 95% CI 1.2 to 3.7). CONCLUSIONS Among medical doctors, cancer screening counselling was provided to their patients more frequently for doctors with family medicine or internal medicine specialties and for physicians who regularly offered counselling on certain lifestyle behaviours, and those having personally attended colorectal cancer screening. Doctors' own personal practices and knowledge of healthy lifestyles may help doctors to more frequently provide counselling on cancer screening to their patients.

Abstract
OBJECTIVE To understand changes in physician screening practices in response to the 2009 U.S. Preventive Services Task Force recommendation supporting shared decision making (SDM) for mammography in women aged 40-49 years. METHODS We assessed screening completion rates for physicians in the Cleveland Clinic Health System pre-2009 (2006-2008) and post-2009 (2010-2015), and rates for physicians new to the system post-2009. We used mixed effects logistic regression to estimate the odds of a woman receiving screening post-2009. If physicians practiced SDM, we hypothesized their screening rates would change after 2009. To test this, we included each physician's pre-2009 screening rate as a predictor in the model. RESULTS Among 125 physicians, the screening rate increased from 40% to 45% from pre-2009 to post-2009. For physicians new to the health system post-2009 the rate was 32%. In the mixed effects model (N = 17,007), the strongest predictor of mammography receipt among patients post-2009 was their physician's pre-2009 screening rate (aOR:3.57 per 10% increase in pre-2009 rate; 95%CI:1.69-7.50). CONCLUSIONS Whether a woman received a mammogram post-2009 was highly associated with her physicians' pre-2009 screening rate, suggesting physicians are not individualizing screening decisions via SDM. PRACTICE IMPLICATIONS Physicians may need support to effectively practice SDM.

Abstract
BACKGROUND Healthcare systems have adopted different strategies to reduce the burden of cervical cancer. In Poland, a population-based screening program was implemented in 2006, leading to a downward trend in cervical cancer burden. However, screening rates are still low in relation to other EU member states. In Poland, Pap smears are mainly performed by gynecologists rather than Primary Health Care (PHC) physicians. Little is known about the experiences and attitudes of the latter regarding cervical cancer screening in a PHC setting. METHODS A cross-sectional questionnaire-based survey was carried out among 43 PHC physicians from the Malopolska region in Poland. Barriers and attitudes towards cytology in a PHC setting were evaluated. RESULTS Approximately 35% of surveyed physicians reported having experience in performing cytology. Almost 75% of PHC physicians lacked the necessary equipment in their office to perform the screening. None of the studied physicians performed Pap smears in their office at the time. The reasons included: shortage of competence (78.57%) and time (69.05%), the perception of Pap smears as a task for gynecologists (69.05%), the lack of financial incentives (61.90%), and the belief that their patients would be unwilling to undergo the test in their PHC physician's office (33.33%). More than three quarters (76.74%) declared they would be ready to perform Pap smears if the tests were additionally paid. No significant associations between PHC physicians' characteristics and their willingness to perform cytology screening were found. CONCLUSION The primary barrier to perform Pap smears by PHC physicians does not lie in their personal reluctance but in the organization of the healthcare system. Provision of required training and proper funding allocation can likely improve the screening rate of cervical cancer in Poland.

Abstract
Over the past few decades, increasing efforts have been made to improve the understanding of, and treatment options for, lung adenocarcinoma (LUAD). However, considering the heterogeneity of LUAD, precise proteomics-based characterization at the molecular level is an urgent clinical requirement for effective treatment. Formalin-fixed, paraffin-embedded (FFPE) tissue is a good option as the working tool for proteomics studies. The present study aimed to obtain a global protein profile using LUAD FFPE tissue samples. Using a quantitative proteomics approach, the study revealed that 360 proteins were significantly more highly expressed in LUAD than in adjacent nontumor lung tissues. Also, 19 differentially expressed membrane proteins were found to be primarily responsible for immune processes. Epidermal growth factor (EGF)-like domain and laminin EGF domain showed markedly different expression levels between cancer tissues and tumor-adjacent normal tissues. Furthermore, Gene Ontology functional enrichment analysis showed that significantly upregulated proteins were associated with the endoplasmic reticulum lumen, protein disulfide isomerase activity, vitamin binding, cell cycle G1/S phase transition, to name but a few. Also, numerous kinases and post-translational modification enzymes were significantly upregulated across all eight LUAD samples compared with paracarcinoma tissues. Proteomics analysis revealed that AAA domain containing 3A (ATAD3a), a member of the ATPase family, was highly expressed in LUAD tissues, which was supported by immunohistochemical analysis. Furthermore, the study confirmed that ATAD3a enhanced the cisplatin sensitivity of LUAD cells. Collectively, the findings of the present study provide new potential candidate targets in patients with LUAD, and may aid auxiliary LUAD diagnosis and surveillance in a noninvasive manner.
