Variations in Practice and Geographic Disparities Between Dedicated Multidisciplinary Clinics for BRCA1/BRCA2 Mutation Carriers in Israel.

BACKGROUND: Population screening for the BRCA mutations in Ashkenazi Jewish women was recently implemented in Israel and is expected to lead to a 10-fold increase in the diagnosis of asymptomatic carriers. Performing the screening follow-up within multidisciplinary dedicated clinics for carriers is recommended for early detection and risk reduction. OBJECTIVES: : To determine the availability, capacity, and practices of dedicated screening clinic for BRCA carriers in Israel. METHODS: A telephone-based survey of all public hospitals in Israel was conducted October 2020 to August 2021 to determine whether they had a dedicated clinic. Dedicated clinics were defined as multidisciplinary screening clinics offering at least breast and gynecological screening and risk reducing services on site. The clinic director or nurse navigator answered a questionnaire about screening practices followed by a semi-structured interview. RESULTS: Of the ten dedicated BRCA clinics found in Israel, nine participated. Approximately 4500 BRCA carriers are currently being followed. No specialized clinics are available in the southern district or in the northernmost half of the northern district of Israel, leading to a disparity between periphery and center. Screening recommendations, although asserted as adhering to international guidelines, vary among clinics including age at initiating of clinical exam, use of adjunct imaging modalities, and follow-up during lactation and after risk reducing surgery. CONCLUSIONS: There is a suboptimal distribution of dedicated clinics for BRCA carriers in Israel. Nationally centralized attempt to create guidelines that will unify screening practices is warranted, especially considering the expected increase in demand.

Correlation between cumulative mammographic density and age-specific incidence of breast cancer: A biethnic study in Israel.

Women with the most extensive breast density, have a 4- to 6-fold higher cancer risk than women with the lowest density. This cross-sectional study evaluated associations of cumulative mammographic density in two distinct ethnic groups with the respective age-specific breast cancer incidences in the population. The study compared four cohorts of 200 women each aged 35 to 49 and 50 to 74, representing Jewish and Arab ethnicity. Breast density measures were calculated from screening mammograms, using a thresholding software (Cumulus). Breast cancer specific incidence values were obtained from the National Cancer Registry. The percent mammographic density was lower for women aged 50 to 74 than 35 to 49 years, both for Jews: 11.7 vs 23.1 and for Arabs: 11.6 vs 18.3. In contrast, the cumulative density increased with age, from 37.30 to 181.24 in Jews, compared to 21.26 to 108.03 in Arabs. Similar trends in breast cancer incidence rates per 100 000 in the Israeli population were apparent, with an increase from 92.95 to 381.91 in Jews, compared to 48.6 to 244.44 in Arabs. Comparing cumulative density of the cohort with respective age-specific breast cancer incidence in the population yielded a highly significant correlation: Jews; r = .97, P < .0001 and Arabs: r = .86, P = .007. A strong association was found between the log of cumulative density and the log of cancer incidence, as well. Our study identified correlations between cumulative mammographic density and breast cancer incidence in two distinct populations. The findings should prompt research to enhance our understanding of the pathogenesis of breast cancer, and lead to novel insights into measures of prevention.

Group Mentoring for Junior Medical Students-the Mentor in the Reflection Cycle.

PURPOSE: To describe the experience and perceptions of physicians involved in group mentoring of undergraduate pre-clinical medical students. METHOD: We conducted a cross-sectional questionnaire-based survey on perceptions of mentors regarding their motivation, personal development, reflective experience, and burnout. All the participants were mentors to undergraduate pre-clinical medical students in the course "Becoming a Physician." This unique course focuses on various aspects of medical professionalism and aims to increase awareness and sensitivity to patients, especially of disadvantaged populations, and to promote sensitive effective communication skills. Mentors in the course are expected to serve as role models to their students. RESULTS: Of 36 mentors, 33 (91.7%) responded. The most frequent motivations to join the course were to contribute to students' personal, social, and professional development and to contribute to educating more compassionate physicians. The topics discussed most in the groups were the meaning of being a physician and ethical dilemmas. Mentors expressed that they gained professional growth and opportunities to reflect on the complexity of physicians' training and work. They perceived their highest success as being able to serve as role models for their students and provide them broad perspectives. Mentors stated that they failed in trying to facilitate content learning, and were disturbed by students' lack of punctuality. Group mentors scored relatively low on the Maslach Burnout Inventory for Physicians. DISCUSSION: This study provides insights on the experience of mentorship of medical school students, and on mentors' perceptions regarding their teaching experience and personal and professional development.

Early assessment of the first wave of the COVID-19 pandemic on cancer screening services: The International Cancer Screening Network COVID-19 survey.

Screening can decrease the burden of breast, cervical, and colorectal cancers. The COVID-19 pandemic led many countries to suspend cancer screening services as part of their response to the pandemic. The International Cancer Screening Network (ICSN) carried out an online survey to assess the effects of the first wave of the COVID-19 pandemic on cancer screening. A 33-item survey was distributed to 834 email addresses to gather information about settings and assess decision-making processes that led to cancer screening suspension. Information about communication, impact on resources, and patient follow-up was collected. Quantitative data was analyzed as frequencies overall and by setting, while a comment section under each survey item captured nuanced details. Responses were recategorized into 66 settings, representing 35 countries. Most settings suspended cancer screening services (n = 60, 90.9%) in March 2020 (n = 45, 68.2%), guided by a government decision (n = 51, 77.3%). Few settings made the decision whether to suspend services based on a preparedness plan (n = 17, 25.8%). In most settings, professionals were reassigned (n = 41, 62.1%) and infrastructure repurposed (n = 35, 53.0%). The first wave of the COVID-19 pandemic has had profound effects on cancer screening worldwide, including the suspension of services in almost all settings. Most settings were unprepared to deal with the scale of the pandemic but demonstrated flexibility in the response. These results contribute to inform, through experiences and lessons learned, the next steps for the global cancer screening community to further evaluate the impact of COVID-19 and prepare for future disruptions.

Mechanisms involved in the formation of professional identity by medical students.

BACKGROUND: Despite in-depth discussions regarding professional identity of doctors, there is still a gap in our understanding of how this professional identity actually evolves. OBJECTIVE: To outline some major mechanisms involved in formation of medical students' professional identity. METHODS: A qualitative study based on thematic analysis. 296 diary entries, written by eight medical students as part of the three-year course 'Becoming a Physician,' were reviewed. The course, conducted in small groups, gradually exposes students to the clinical field, and emphasizes awareness to marginalized populations, and interpersonal communication skills. RESULTS: Following the social constructivist learning theory, where learners individually and socially construct meaning attributed to their experiences, we identified three major mechanisms based on students' written reflections. These include linking current experiences to past; comparing different types or aspects of knowledge, doctors or medicine; and future perspective taking. CONCLUSIONS: This study sheds light on the possible mechanisms used by medical students in forming their professional identity prior to their clinical training. Knowing these mechanisms can help medical educators better understand and support their students in formation of their professional identities. Conducting reflective writing could serve as an effective tool for learners to comprehend the meanings of their experiences.

Epidemiologic Surveillance in Israel of Cryptosporidium, a Unique Waterborne Notifiable Pathogen, and Public Health Policy.

BACKGROUND: Cryptosporidium is a major threat to water supplies worldwide. Various biases and obstacles in case identification are recognized. In Israel, Cryptosporidiosis was included among notifiable diseases in 2001 in order to determine the burden of parasite-inflicted morbidity and to justify budgeting a central drinking water filtration plant. OBJECTIVES: To summarize the epidemiologic features of 14 years of Cryptosporidium surveillance and to assess the effects of advanced water purification treatment on the burden of disease. METHODS: From 2001 to 2014, a passive surveillance system was used. Cases were identified based on microscopic detection in stool samples. Confirmed cases were reported electronically to the Israeli Ministry of Health. Overall rates as well as age, gender, ethnicity and specific annual incidence were calculated per 100,000 population in five age groups: 0-4, 5-14, 15-44, 45-64, > 65 years. RESULTS: A total of 522 Cryptosporidium cases were reported in all six public health districts. More cases were detected among Jews and among males, and mainly in young children, with a seasonal peak during summer. The Haifa sub-district reported 69% of the cases. Most were linked to an outbreak from the summer of 2008, which was attributed to recreational swimming pool activity. Cases decreased after installation of a central filtration plant in 2007. CONCLUSIONS: As drinking water in Israel is treated to maximal international standards, the rationale for further inclusion of Cryptosporidium among mandatory notifiable diseases should be reconsidered. Future surveillance efforts should focus on timely detection of outbreaks using molecular high-throughput testing.

Delayed Colonoscopy Following a Positive Fecal Test Result and Cancer Mortality.

BACKGROUND: A fecal test followed by diagnostic colonoscopy for a positive result is a widely endorsed screening strategy for colorectal cancer (CRC). However, the relationship between the time delay from the positive test to the follow-up colonoscopy and CRC mortality has not been established. METHODS: From a population-based screening program, we identified CRC patients newly diagnosed from 2005 through 2015 by a positive fecal occult test followed by a colonoscopy. The primary outcome measure was CRC-specific mortality according to four categories for the time elapsed between the positive result and the subsequent colonoscopy. RESULTS: The 1749 patients underwent colonoscopies within 0-3 months (n = 981, 56.1%), 4-6 months (n = 307, 17.5%), 7-12 months (n = 157, 9.0%), and later than 12 months (n = 304, 17.4%). CRC-specific deaths according to exposure groups were: 13.8% (135 of 981) for 0-3 months, 10.7% (33 of 307) for 4-6 months (crude hazards ratio [HR] = 0.74, 95% confidence interval [CI] = 0.51 to 1.14), 11.5% (18 of 157) for 7-12 months (crude HR = 0.83, 95% CI = 0.51 to 1.42), and 22.7% (69 of 304) for longer than 12 months (crude HR = 1.40, 95% CI = 1.04 to 1.90). The only variable that was associated with mortality risk was the number of positive slides (P = .003). High positivity was twice the value in the 0-3 as the longer-than-12 months group: 51.9% vs 25.0% and similar for the 4-6 and 7-12 months groups (38.1% and 36.5%), respectively. The adjusted HRs for CRC mortality were 0.81 (95% CI = 0.55 to 1.19); 0.83 (95% CI = 0.50 to 1.41), and 1.53 (95% CI = 1.13 to 2.12, P = .006) for the 4-12, 7-12, and longer-than-12-months groups, respectively, compared with the shortest delay group. CONCLUSIONS: Among screen-diagnosed CRC patients, performance of colonoscopy more than 12 months after the initial positive fecal occult blood test was associated with more advanced disease and higher mortality due to CRC.
