AXIN2-related oligodontia-colorectal cancer syndrome with cleft palate as a possible new feature.

Pathogenic variants in AXIN2 have been associated with tooth agenesis, colon polyps, and colon cancer. Given the rare nature of this phenotype, we set out to collect additional genotypic and phenotypic information. Data were collected via a structured questionnaire. Sequencing was performed in these patients mostly due to diagnostic purpose. A little more than half of the AXIN2 variant carriers were identified by NGS; other six were family members. Here, we report 13 individuals with a heterozygous AXIN2 pathogenic/likely pathogenic variant who have a variable expression of oligodontia-colorectal cancer syndrome (OMIM 608615) or oligodontia-cancer predisposition syndrome (ORPHA 300576). Three individuals from one family also had cleft palate, which might represent a new clinical feature of AXIN2 phenotype, also given the fact that AXIN2 polymorphisms have been found in association with oral clefting in population studies. AXIN2 has already been added to multigene cancer panel tests; further research should be conducted to determine whether it should be added to cleft lip/palate multigene panels. More clarity about oligodontia-colorectal cancer syndrome, about the variable expression, and associated cancer risks is needed to improve clinical management and to establish guidelines for surveillance. We collected information about the surveillance that was advised, which might support clinical management of these patients.

Multicentre Analysis of Cost, Uptake and Safety of Canadian Multidisciplinary Pancreatic Cyst Guidelines.

Pancreatic cystic lesions (PCLs) are common, with several guidelines providing surveillance recommendations. The Canadian Association of Radiologists published surveillance guidelines (CARGs) intended to provide simplified, cost-effective and safe recommendations. This study aimed to evaluate cost savings of CARGs compared to other North American guidelines including American Gastroenterology Association guidelines (AGAG) and American College of Radiology guidelines (ACRG), and to evaluate CARG safety and uptake. This is a multicentre retrospective study evaluating adults with PCL from a single health zone. MRIs completed from September 2018-2019, one year after local CARG guideline implementation, were reviewed to identify PCLs. All imaging following 3-4 years of CARG implementation was reviewed to evaluate true costs, missed malignancy and guideline uptake. Modelling, including MRI and consultation, predicted and compared costs associated with surveillance based on CARGs, AGAGs and ACRGs. 6698 abdominal MRIs were reviewed with 1001 (14.9%) identifying PCL. Application of CARGs over 3.1 years demonstrated a >70% cost reduction compared to other guidelines. Similarly, the modelled cost of surveillance for 10-years for each guideline was $516,183, $1,908,425 and $1,924,607 for CARGs, AGAGs and ACRGs respectively. Of patients suggested to not require further surveillance per CARGs, approximately 1% develop malignancy with fewer being candidates for surgical resection. Overall, 44.8% of initial PCL reports provided CARG recommendations while 54.3% of PCLs were followed as per CARGs. CARGs are safe and offer substantial cost and opportunity savings for PCL surveillance. These findings support Canada-wide implementation with close monitoring of consultation requirements and missed diagnoses.

Cervicovaginal detection of microorganisms in patients with type 2 diabetes

The purpose of the present investigation was to report the presence of cervicovaginal microorganisms most frequently found in cervicovaginal exfoliative smears (Papanicolaou) of patients with type 2 diabetes. Cervical-vaginal exfoliative cytologist was performed on an open population to all patients who attended from March 2010 to March 2020 in the within the framework of the early cancer detection program, gynecological interrogations were applied to 1587 patients who, after taking cell samples, were processed using the Papanicolaou staining technique modified by the same for subsequent microscopic diagnosis. Of the results obtained from the 1587 patients studied, 148 (9.32%) suffer from type 2 diabetes mellitus and of these only 130 (87.83%) showed at least one microorganism under microscopic observation, being Candida spp., the most found microorganism in samples from patients with type 2 diabetes. In conclusions, type 2 diabetes is a disease that predisposes to the appearance of microorganisms and cervicovaginal infections, particularly by Candida spp., therefore, there is a need for surveillance guidelines and efforts to reverse this disease and its complications.

Adherence to Post-polypectomy Surveillance Guidelines at a Large District General Hospital.

Introduction In 2020, the British Society of Gastroenterologists(BSG), the Association of Coloproctology of Great Britain and Ireland (ACPGBI), and Public Health England (PHE) published joint guidelines regardingpost-polypectomy surveillance. This study aimed to establish clinician adherence at the Royal Devon University Healthcare NHS Foundation Trust to the 2020 guidelines compared to the now-retired 2010 guidelines. Materials and Methods Data on 152 patients treated under the 2010 guidelines and 133 patients treated under the 2020 guidelines were collected retrospectively from the hospital's colonoscopy database. Data were analysed to determine whether patients who had a colonoscopy fulfilled BSG/ACPGBI/PHE guidelines for follow-up. Costs were estimated using the price of colonoscopy in the NHS National Schedule. Results Approximately 41.4% (63/152) of patients were adherent to the 2010 guidelines while 66.2% (88/133) of patients were adherent to the 2020 guidelines. The difference in adherence rate was 24.7% (95% confidence interval 13.5% - 35.9%, p<0.0001). Nearly 37% (35/95) of patients who would have been followed up under the 2010 guidelines did not receive any follow-up as a result of the 2020 guidelines. This represents a cost saving of £36,892.28 per year in our hospital. Approximately 47% (28/60) of patients treated under the 2020 guidelines had surveillance colonoscopy planned when the guidelines recommended no follow-up. If every clinician were fully adherent to the 2020 guidelines, then a further £29,513.82 per year would have been saved. Discussion and Conclusion Following the introduction of the 2020 guidelines, adherence to polyp surveillance guidelines increased in our hospital. However, nearly half of the colonoscopies were performed unnecessarily due to non-adherence. Furthermore, our results demonstrate that the 2020 guidelines have decreased the need for follow-up.

Piloting a hospital-based road traffic injury surveillance system in Nairobi County, Kenya, 2018–2019

BackgroundKenya's estimated road traffic injury (RTI) death rate is 27.8/100,000 population, which is 1.5 times the global rate. Some RTI data are collected in Kenya; however, a systematic and integrated surveillance system does not exist. Therefore, we adopted and modified the World Health Organization's injury surveillance guidelines to pilot a hospital-based RTI surveillance system in Nairobi County, Kenya. MethodsWe prospectively documented all RTI cases presenting at two public trauma hospitals in Nairobi County from October 2018–April 2019. RTI cases were defined as injuries involving ≥1 moving vehicles on public roads. Demographics, injury circumstances, and outcome information were collected using standardized case report forms. The Kampala Trauma Score (KTS) was used to assess injury severity. RTI cases were characterized with descriptive statistics. ResultsOf the 1,840 RTI cases reported during the seven-month period, 73.2% were male. The median age was 29.8 years (range 1–89 years). Forty percent (n = 740) were taken to the hospital by bystanders. Median time for hospital arrival was 77 min. Pedestrians constituted 54.1% (n = 995) of cases. Of 400 motorcyclists, 48.0% lacked helmets. Similarly, 65.7% of bicyclists (23/35) lacked helmets. Among 386 motor vehicle occupants, 59.6% were not using seat belts (19.9% unknown). Seven percent of cases (n = 129) reported alcohol use (49.0% unknown), and 8.8% (n = 161) reported mobile phone use (59.7% unknown). Eleven percent of cases (n = 199) were severely injured (KTS <11), and 220 died. ConclusionWe demonstrated feasibility of a hospital-based RTI surveillance system in Nairobi County. Integrating information from crash scenes and hospitals can guide prevention.

Esophageal Surveillance Practices in Esophageal Atresia Patients: A Survey by the Eastern Pediatric Surgery Network

IntroductionEndoscopic surveillance guidelines for patients with repaired esophageal atresia (EA) rely primarily on expert opinion. Prior to embarking on a prospective EA surveillance registry, we sought to understand EA surveillance practices within the Eastern Pediatric Surgery Network (EPSN). MethodsAn anonymous, 23-question Qualtrics survey was emailed to 181 physicians (surgeons and gastroenterologists) at 19 member institutions. Likert scale questions gauged agreement with international EA surveillance guideline-derived statements. Multiple-choice questions assessed individual and institutional practices. ResultsThe response rate was 77%. Most respondents (80%) strongly agree or agree that EA surveillance endoscopy should follow a set schedule, while only 36% claimed to perform routine upper GI endoscopy regardless of symptoms. Many institutions (77%) have an aerodigestive clinic, even if some lack a multi-disciplinary EA team. Most physicians (72%) expressed strong interest in helping develop evidence-based guidelines. ConclusionsOur survey reveals physician agreement with current guidelines but weak adherence. Surveillance methods vary greatly, underscoring the lack of evidence-based data to guide EA care. Aerodigestive clinics may help implement surveillance schedules. Respondents support evidence-based protocols, which bodes well for care standardization. Results will inform the first multi-institutional EA databases in the United States (US), which will be essential for evidence-based care. Level of EvidenceThis is a prognosis study with level 4 evidence.

Putting non-communicable disease data to work in Vietnam: an investigation of community health surveillance capacity

IntroductionDespite the public health system’s critical role in non-communicable disease (NCD) surveillance in Vietnam, limited evidence exists on the implementation of NCD surveillance activities within these systems and the need for capacity building across different system levels to meet expected NCD surveillance goals. This study aimed to evaluate the status of and describe factors affecting the implementation of NCD surveillance activities and to identify the NCD surveillance capacity building needs of the public health system in Vietnam.MethodsWe used a mixed-methods approach in four provinces, conducting self-completed surveys of staff from six Preventive Medicine Institutes (PHI), 53 Centres for Disease Control (CDC) and 148 commune health stations (CHS), as well as 14 in-depth interviews and 22 focus group discussions at four PHI, four CDC, and eight district health centres and CHS.ResultsStudy findings highlighted that although Vietnam has a well-functioning NCD surveillance system, a number of quality issues related to NCD surveillance data were salient. Multifactorial reasons were identified for incomplete, unconfirmed, and inaccurate mortality data and current disease surveillance data. Data on NCD management and treatment were reported to be of better quality than data for screening, targeted treatment, and counselling communication. Main factors affected the effective implementation of NCD surveillance, namely lack of complete and specific guidelines for NCD surveillance, limitations in human resource capacity within NCD departments, and shortage of funding for NCD surveillance activities.ConclusionStudy findings provide practical strategies for strengthening health system capacity for NCD surveillance through developing policies, guidelines, and standardised tools to guide NCD surveillance and a road map for integrated NCD surveillance, developing training packages and manuals for all levels of the health system, and conducting utilisation-focused surveillance training programs.

Evaluation of Implementation of Dengue Hemorrhagic Fever Surveillance

Background: Dengue fever is still endemic in Indonesia. The government launched a DHF surveillance program. There was found some problems in the surveillance system, and the trend of dengue fever in 2016-2020 which had increased at the Pusat Kesehatan Masyarakat (Puskesmas) of Bantul II. This study aims to evaluate the implementation of DHF surveillance at the Puskesmas Bantul II. Method: This research is an evaluation of the CIPP model (Context, Input, Process, Product) with a qualitative-descriptive approach. This research was conducted in June-July 2021 at the Puskesmas Bantul II. Data was collected by interviewing 5 (five) informants. Results: The implementation of DHF surveillance at the Puskesmas Bantul II is based on input, human resources aren’t skilled epidemiologists, officers still hold concurrent positions, and haven’t received epidemiology/surveillance training. The infrastructure was complete, sufficient, and functioning properly. There is no specific allocation of funds for DHF surveillance. There are SOPs and surveillance guidelines, and DHF activities. Based on the process, the collection, processing, presentation, data analysis, and information dissemination have been carried out. The recommendations haven’t been implemented. The Health Office provides regular feedback, monitoring, and evaluation. Based on the output, reporting once a month on time. But its aren’t complete, some files are missing and damaged. Conclusion: The implementation of DHF surveillance at the Puskesmas Bantul II has been carried out, but several aspects of the input, process, and output do not match the indicators, so it affects the outcomes that are not in accordance with national standards.

Antimicrobial Resistance and Pathogenicity of Aliarcobacter butzleri Isolated from Poultry Meat

Aliarcobacter butzleri (A. butzleri) is an emergent zoonotic food-related pathogen that can be transmitted through the consumption of poultry meat. Data regarding the pathogenicity and resistance of A. butzleri are still scarce, and the presence of virulent MDR strains of this zoonotic pathogen in poultry meat is an issue of particular concern to public health. This study aimed to characterize the pathogenicity and antimicrobial resistance profiles of A. butzleri strains isolated from poultry meat sold at retail markets in São Paulo, Brazil. The minimum inhibitory concentrations of 27 strains were determined using the broth microdilution method. The results showed that 77.7% of the isolates were resistant to clindamycin, 62.9% to florfenicol, 59.2% to nalidixic acid, 11.1% to azithromycin, 7.4% to ciprofloxacin and telithromycin, and 3.7% to erythromycin and tetracycline, although all were susceptible to gentamicin. Moreover, 55.5% of the virulent isolates were also multidrug-resistant (MDR). Three strains were selected for pathogenicity tests in vitro and in vivo. The tested strains expressed weak/moderate biofilm production and showed a diffuse adhesion pattern (3 h) in HeLa cells and toxicity in Vero cells (24 h). Experimental inoculation in 11-week-old chicks induced a transitory inflammatory enteritis. Intestinal hemorrhage and destruction of the intestinal crypts were observed in the rabbit ileal loop test. Considering the fact that Brazil is a major exporter of poultry meat, the data from this study point to the need of improvement of the diagnostic tools, as well as of the adoption of surveillance guidelines and more specific control strategies to ensure food safety, reducing the presence of pathogenic MDR strains in broilers.

Korean Guidelines for Postpolypectomy Colonoscopic Surveillance: 2022 revised edition.

Colonoscopic polypectomy is effective in decreasing the incidence and mortality of colorectal cancer (CRC). Premalignant polyps discovered during colonoscopy are associated with the risk of metachronous advanced neoplasia. Postpolypectomy surveillance is the most important method for managing advanced metachronous neoplasia. A more efficient and evidence-based guideline for postpolypectomy surveillance is required because of the limited medical resources and concerns regarding colonoscopy complications. In these consensus guidelines, an analytic approach was used to address all reliable evidence to interpret the predictors of CRC or advanced neoplasia during surveillance colonoscopy. The key recommendations state that the high-risk findings for metachronous CRC following polypectomy are as follows: adenoma ≥10 mm in size; 3 to 5 (or more) adenomas; tubulovillous or villous adenoma; adenoma containing high-grade dysplasia; traditional serrated adenoma; sessile serrated lesion containing any grade of dysplasia; serrated polyp of at least 10 mm in size; and 3 to 5 (or more) sessile serrated lesions. More studies are needed to fully comprehend the patients who are most likely to benefit from surveillance colonoscopy and the ideal surveillance interval to prevent metachronous CRC.

P301 Outcomes following colectomy for patients with Ulcerative Colitis, ten years of data from a tertiary referral centre

Abstract Background Patients who undergo subtotal colectomy for Ulcerative Colitis (UC) have a persistent risk of colorectal cancer (CRC) in the retained rectum and this increases overtime. There are currently no guidelines for rectal surveillance in this group. We aimed to assess the outcome following colectomy for patients with UC over a ten year period. Methods We conducted a retrospective analysis of patients with UC who underwent colorectal surgery in a tertiary referral centre. The Hospital In-Patient Enquiry system and the St Vincent's Hospital IBD Database were used to identify patients. Patients with colorectal cancer were excluded. Results In a six year period one-hundred and seventy six bowel surgeries were carried out for patients with Inflammatory Bowel Disease. Sixty five of these procedures were performed on patients with UC, eight of which would subsequently be re-diagnosed with Crohn’s Disease. 73.6% (n=42) had a completion proctectomy within ten years, 12% (n=7) were lost to follow up and 5% (n=3) died from non-gastrointestinal disorders. 8.7% (n=5) retained their rectum after ten years. For patients who had a completion proctectomy the median time to surgery was two years. Most of these patients did not have surveillance within the twenty four month time frame. Patients who had a completion proctectomy between three and ten years underwent surveillance endoscopy on average two occasions. All patients in the retained rectum group had surveillance proctoscopy with a median frequency of 2.4 years. The risk of further surgery was a factor for two patients due to obesity and decompensated liver disease. A third patient had an ileorectal anastamosis abroad and continues to have active rectal disease. Dysplasia was found in the rectum of the fourth patient thirteen years post colectomy. The final patient refused surgery but agreed to endoscopic surveillance. A rectal adenocarcinoma was diagnosed ten years post-operation. Conclusion Despite the absence of guidelines for completion proctectomy and/or surveillance of the retained rectal stump, three quarters of our UC patients had undergone completion proctectomy within ten years. A small but significant number of patients have a residual rectal stump after ten years, they require CRC surveillance and clear guidelines on this are needed.

Risk of Renal or Urinary Related Hospitalization in Survivors of Childhood Cancer: Results from the French Childhood Cancer Survivor Study.

Hospitalization rates can be used as an indirect indicator of the burden and severity of adverse health outcomes in childhood cancer survivors (CCS). We aimed to determine the long-term risks of hospitalization related to renal and urinary diseases among 5-year CCS. The French Childhood Cancer Survivor Study cohort was linked with data from the French National Healthcare System database, which enabled the identification of hospitalizations related to renal or urinary diseases. Clinical and detailed treatment data were collected from medical records. Dose-volume histograms were estimated for all patients treated with radiotherapy. Standardized Hospitalization Ratios and absolute excess risks (AER) were calculated. Relative risks were estimated using Poisson regression. A total of 5,498 survivors were followed for 42,118 person-years (PY). Survivors experience 2.9 times more renal hospitalizations than expected in the general population, with an AER of 21.2/10,000 PY. Exposing more than 10% of the kidneys' volume to at least 20 Gray increases the risk of being hospitalized for renal causes by 2.2 (95% confidence interval, 1.3-3.6). Nephrectomized survivors treated with high doses of ifosfamide (>60 g/m²) have an extremely high risk of hospitalization for renal causes. Patients with comorbidities have about a 3-fold higher risk, and nephrectomized patients a 2-fold higher risk of being hospitalized for renal causes compared with other subjects. In the case of hospitalization for urinary causes, treatment by anthracycline administration was found to be associated with an almost 2-fold higher risk of hospitalization compared with the general population. These results support the need for careful monitoring of long-term renal diseases in survivors who have undergone nephrectomy, those treated with high doses of radiation (≥20 Gy) even to small volumes of the kidneys, and those with predisposing risk factors. This study provides new evidence with potential impact on surveillance guidelines related to dose-volume indicators associated with renal toxicity.

Sex-differences in socioeconomic status and health-seeking behaviour among tuberculosis patients in transitional Albania in 2012-2013

Aim: There is little scientific evidence about the main determinants of sex discrepancies in tuberculosis rates in Albania. The aim of this study was to assess the sex-differences in socioeconomic characteristics, knowledge and attitudes about tuberculosis and access to health care among tuberculosis patients in Albania, a transitional country in the Western Balkans. Methods: Our analysis involved all the new cases of pulmonary tuberculosis diagnosed in Albania during the period June 2012 – June 2013 (N=197; 69% males; overall mean age: 44±19 years). The recording and reporting system of tuberculosis cases was performed according to the WHO and EuroTB Surveillance guidelines. Information on socioeconomic characteristics of the patients, knowledge and attitudes about tuberculosis and access to health care was also collected. Logistic regression was used to assess the correlates of sex-differences among tuberculosis patients. Results: In multivariable-adjusted models, female sex was positively related to unemployment (OR=3.7, 95%CI=1.8-7.7), bad living conditions (OR=3.0, 95%CI=1.4-6.5), a longer distance to health care facility (OR=3.0, 95%CI=1.4-6.3), a lower level of knowledge about tuberculosis (OR=3.1, 95%CI=1.3-7.1) and a higher level of stigma against tuberculosis (OR=3.6, 95%CI=1.6-7.9). Conclusion: Our study informs about selected correlates of sex-differences in tuberculosis rates in post-communist Albania. Future studies should more vigorously explore determinants of sex-differences in tuberculosis rates in countries of the Western Balkans.

Clinical evaluation of late outcomes in Dutch childhood cancer survivors: Methodology of the DCCSS LATER 2 study.

Childhood cancer survivors face late health problems; despite advances in research, details on risk remain unclear. We describe the methodological aspects of the Dutch Childhood Cancer Survivor Study (DCCSS) cross-sectional clinical study (LATER 2 study). From the multi-center DCCSS LATER cohort of 6165 five-year survivors diagnosed during 1963-2001, we invited 4735 eligible survivors in 2016, as well as siblings and parents of survivors. Gaps in evidence identified during development of surveillance guidelines were translated into clinical research questions for 16 outcome-specific subprojects. The regular care visit to the LATER outpatient clinic forms the backbone of outcome assessment complemented with research-defined measurements (physical examination, clinical tests, questionnaires). Furthermore, blood/saliva samples were taken for deoxyribonucleic acid (DNA) extraction. In total, 2519 (53.2%) survivors participated in the LATER 2 study. When comparing participants with nonparticipants, we observed that males, CNS survivors, and those treated with surgery only were less likely to participate. Of the participating survivors, 49.3% were female. Median time since childhood cancer diagnosis was 26.9years (range 14.8-54.7years) and median attained age was 34.4years (range 15.4-66.6years). The high-quality data generated in the LATER 2 study will provide valuable insights into risks of and risk factors for clinical and physical and psychosocial health outcomes and factors for early recognition of those health outcomes in long-term childhood cancer survivors. This will contribute to fill in important gaps in knowledge and improve the quality of life and care for childhood cancer survivors.

Using New Hampshire Colonoscopy Registry data to assess United States and European post-polypectomy surveillance guidelines.

Our goal was to compare the updated European Society of Gastrointestinal Endoscopy (ESGE) and United States Multi-Society Task Force on Colorectal Cancer (USMSTF) high risk groups in predicting metachronous advanced neoplasia on first follow-up colonoscopy and long-term colorectal cancer (CRC). We compared advanced metachronous neoplasia risk (serrated polyps ≥ 1 cm or with dysplasia, advanced adenomas [≥ 1 cm, villous, high grade dysplasia], CRC) on first surveillance colonoscopy in patients with high risk findings according to ESGE versus USMSTF guidelines. We also compared the positive and negative predictive values (PPV, NPV) of both guidelines for metachronous neoplasia. The risk for metachronous neoplasia in our sample (n = 20 458) was higher in the high risk USMSTF (3 year) (13.6 %; 95 %CI 12.3-14.9) and ESGE groups (13.6 %; 95 %CI 12.3-15.0) compared with the lowest risk USMSTF (5.1 %; 95 %CI 4.7-5.5; P < 0.001) and ESGE categories (6.3 %; 95 %CI 6.0-6.7; P < 0.001), respectively. Adding other groups such as USMSTF 5-10-year and 3-5-year groups to the 3-year category resulted in minimal change in the PPV and NPV for metachronous advanced neoplasia. High risk ESGE (hazard ratio [HR] 3.03, 95 %CI 1.97-4.65) and USMSTF (HR 3.07, 95 %CI 2.03-4.66) designations were associated with similar long-term CRC risk (CRC per 100 000 person-years: USMSTF 3-year group 3.54, 95 %CI 2.68-4.68; ESGE high risk group: 3.43, 95 %CI 2.57-4.59). Performance characteristics for the ESGE and USMSTF recommendations are similar in predicting metachronous advanced neoplasia and long-term CRC. The addition of risk groups, such as the USMSTF 5-10-year and 3-5-year groups to the USMSTF 3-year category did not alter the PPV or NPV significantly.

Surveillance Imaging after Primary Diagnosis of Ductal Carcinoma in Situ.

Background Guidelines recommend annual surveillance imaging after diagnosis of ductal carcinoma in situ (DCIS). Guideline adherence has not been characterized in a contemporary cohort. Purpose To identify uptake and determinants of surveillance imaging in women who underwent treatment for DCIS. Materials and Methods A stratified random sample of women who underwent breast-conserving surgery for primary DCIS between 2008 and 2014 was retrospectively selected from 1330 facilities in the United States. Imaging examinations were recorded from date of diagnosis until first distant recurrence, death, loss to follow-up, or end of study (November 2018). Imaging after treatment was categorized into 10 12-month periods starting 6 months after diagnosis. Primary outcome was per-period receipt of asymptomatic surveillance imaging (mammography, MRI, or US). Secondary outcome was diagnosis of ipsilateral invasive breast cancer. Multivariable logistic regression with repeated measures and generalized estimating equations was used to model receipt of imaging. Rates of diagnosis with ipsilateral invasive breast cancer were compared between women who did and those who did not undergo imaging in the 6-18-month period after diagnosis using inverse probability-weighted Kaplan-Meier estimators. Results A total of 12 559 women (median age, 60 years; IQR, 52-69 years) were evaluated. Uptake of surveillance imaging was 75% in the first period and decreased over time (P < .001). Across the first 5 years after treatment, 52% of women participated in consistent annual surveillance. Surveillance was lower in Black (adjusted odds ratio [OR], 0.80; 95% CI: 0.74, 0.88; P < .001) and Hispanic (OR, 0.82; 95% CI: 0.72, 0.94; P = .004) women than in White women. Women who underwent surveillance in the first period had a higher 6-year rate of diagnosis of invasive cancer (1.6%; 95% CI: 1.3, 1.9) than those who did not (1.1%; 95% CI: 0.7, 1.4; difference: 0.5%; 95% CI: 0.1, 1.0; P = .03). Conclusion Half of women did not consistently adhere to imaging surveillance guidelines across the first 5 years after treatment, with racial disparities in adherence rates. © RSNA, 2023 Supplemental material is available for this article.

Seizures in trisomy 18: Prevalence, description, and treatment.

Changes in medical intervention over the last decade have improved outcomes for individuals with trisomy 18, the second most common human aneuploidy syndrome at birth. As children with trisomy 18 live longer, a shared concern of medical experts and parents is the occurrence and treatment of seizures. Previously published surveillance guidelines for this condition have not addressed seizure management. Using parent-reported data collected as part of the Tracking Rare Incidence Syndromes project, we report on the prevalence, course, and management of seizures in individuals with trisomy 18. Twenty-eight percent (52/186) of individuals diagnosed with trisomy 18 in our retrospective cohort experienced generalized, focal, or mixed seizures at some point in their lifetime. For many individuals, seizures were effectively managed by broad-spectrum anti-seizure medications. Correlation analysis showed that focal and generalized seizures were more likely to occur in individuals who had previously experienced infantile spasms or central apnea. Electroencephalogram testing should be considered as part of a standard screening approach in individuals with trisomy 18 to enable early diagnosis and treatment of seizures. An international registry that incorporates parent-reported and clinical data for patients with trisomy 18 may facilitate ongoing research and recruitment into clinical trials for seizure management.

Adherence to Recommendations for Repeat Surveillance After Publication of New Postpolypectomy Guidelines.

The 2012 and 2020 US Multi-Society Task Force postpolypectomy guidelines have recommended progressively longer surveillance intervals for patients with low-risk adenomas (LRAs). These guidelines require data from past colonoscopies. We examined the impact of the 2012 guidelines for second surveillance on clinical practice, including the availability of prior colonoscopy data, with the aim of informing the implementation of the 2020 guidelines. We identified surveillance colonoscopies at Stanford Health Care and the Palo Alto Veterans Affairs Health Care System in 3 periods: preguideline (March-August 2012), postguideline (January-June 2013), and delayed postguideline (July-September 2017). We collected data on the most recent previous colonoscopy, findings at the study entry surveillance colonoscopy, and recommendations for subsequent surveillance. Among 977 patients, the most recent prior colonoscopy data were available in 78% of preguideline, 78% of postguideline, and 61% of delayed postguideline cases (P < .001). The fraction of surveillance colonoscopy reports that deferred recommendations awaiting pathology increased from 6% to 11% in preguideline and postguideline to 59% in delayed postguideline cases (P < .001). Overall adherence to guidelines for subsequent surveillance was similar in all 3 periods (54%-67%; P= .089). In the postguideline and delayed postguideline periods combined, a 10-year subsequent surveillance interval was recommended in 0 of 29 cases with LRA followed by normal surveillance colonoscopy. In patients undergoing surveillance, prior colonoscopy data were not always available and recommendations were often deferred awaiting pathology. Adherence to subsequent surveillance guidelines was suboptimal, especially for LRA followed by normal colonoscopy. Strategies addressing these gaps are needed to optimize implementation of the updated 2020 postpolypectomy guidelines.

MRI for screening and surveillance for hepatocellular cancer in NAFLD and NASH

Chronic liver disease is an important risk factor for the development of hepatocellular carcinoma (HCC), with 80%-90% developing in the background of cirrhosis, primarily due to alcohol abuse and chronic viral infection with hepatitis B and C. Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) related HCC is rising due to the global epidemic of obesity and diabetes. NAFLD also potentiates other risk factors of HCC, such as chronic hepatitis C and alcoholic liver injury. Furthermore, HCC may complicate non-cirrhotic NAFLD, greatly expanding the population potentially at risk. Screening and surveillance for HCC with ultrasonography (US) in this patient population pose challenges related to body habitus, liver morphology, and co-morbidities. Magnetic resonance imaging (MRI) applying various image sequence protocols and contrast agents could aid in early detection and improved prognosis of HCC. It is of utmost importance to define the most cost-effective dynamic imaging protocol for use in patients where high-quality ultrasonography images cannot be obtained and for patients undergoing surveillance for lesions identified with US. Furthermore, standardization of MRI protocols will help to define potential unique HCC features in this population. A scoring system including patient-derived factors may help to identify high-risk patients. Standardized protocols as part of prospective cohort studies and randomized clinical trials will help to stratify high-risk patients and to aid the development of professional guidelines for screening and surveillance of HCC in patients with NAFLD and NASH using dynamic imagining techniques.

Barriers to surveillance for hepatocellular cancer among patients with chronic liver disease -providers' perspectives

Aims: Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. While patients who are known to be at high risk for HCC should be under surveillance, only 20% of eligible patients in the United States are surveilled. The aim of this study was to identify providers’ perspectives about patient-, provider- and system-level barriers to surveillance for HCC among high-risk patients and to examine provider knowledge and attitudes related to HCC surveillance. We also explored interventions providers suggested as ways to improve HCC surveillance. Methods: Purposive sampling was used to recruit physicians and nurse practitioners in hepatology, gastroenterology, and primary care (internal and family medicine) from one academic medical center to participate in semi-structured interviews. Interviews were transcribed verbatim, and analyzed deductively and inductively to reveal emergent themes. Results: 22 informants were interviewed. During these interviews, several important themes emerged, including: (1) Provider comfort with managing chronic liver disease and the relationships between hepatology, gastroenterology, infectious disease, and primary care providers; (2) Provider knowledge of guidelines for HCC surveillance in high-risk patients and their knowledge about the impact that HCC surveillance can have; (3) How providers discuss HCC surveillance with their high-risk patients; (4) Provider-Level barriers to surveillance; (5) System-level barriers to surveillance; (6) COVID-19; (7) Patient-level barriers to surveillance, and (8) Suggested interventions to improve HCC surveillance rates. Conclusions: In designing interventions to improve HCC surveillance rates of high-risk patients in the United States, there are important targets at the patient, provider and system levels.
