Obstetrician-Gynecologists’ Knowledge of Health Disparities and Barriers among American Indian/Alaska Native Women in Washington State

Background: Health disparities between American Indian/Alaska Native (AI/AN) women and other races/ethnicities have long been noted. Obstetricians-Gynecologists (Ob-Gyn) play a significant role in well-woman care and are often the first and most frequent point of medical contact for women, particularly among minority and low-income women. Objective: This study aimed to assess Ob-Gyns’ knowledge, beliefs, and practices related to health disparities among AI/AN women. Method: A self-administered questionnaire, consisting of questions about knowledge, beliefs, and practices of health disparities among AI/AN women, was mailed to 722 members of The American College of Obstetricians and Gynecologists (ACOG) practicing in the state of Washington in September 2013-February 2014. Results: The majority of respondents were knowledgeable about numerous health care disparities among non-pregnant AI/AN women, while slightly fewer were aware of disparities among pregnant AI/AN patients. Ob-Gyns reported low confidence in their training and knowledge of AI/AN culture and health disparities, but high confidence in their ability to treat AI/AN patients. Participants reported dissatisfaction with their AI/AN patients’ breastfeeding rates. Conclusion: Ob-Gyn knowledge of health disparities among AI/AN women is adequate. In spite of this, barriers to quality care are still present and increased identification and implementation of effective resources is needed

Total ankle replacement: comparison of the outcomes of STAR and Mobility

Total Ankle Replacement is a recognised treatment for end-stage ankle arthritis and an alternative to arthrodesis. This study reviews a single centre series of prospectively collected outcome measures to determine whether the Mobility performs better than the Scandinavian ankle replacement. The primary outcome measure was the survivorship. Secondary outcome measures consisted of complications and international scoring systems. 147 Scandinavian and 162 Mobility ankle replacements were reviewed at a mean follow up of 12.4 and 7.7 years respectively. The revision rate, which included liner exchange, component exchange or removal of implant was at 7 years 12.3% (18) for Scandinavian and 5.2% (8) for Mobility. The complication rate was 16.5% (22) for Scandinavian compared to 9.9 % (15) for Mobility. The results of our unit compare favourably with previous published studies. In this study the Mobility has been shown to have more favourable results at 7 years compared to the Scandinavian

Detecting Endometrial Cancer by Blood Spectroscopy: A Diagnostic Cross-Sectional Study

Endometrial cancer is the sixth most common cancer in women, with a rising incidence worldwide. Current approaches for the diagnosis and screening of endometrial cancer are invasive, expensive or of moderate diagnostic accuracy, limiting their clinical utility. There is a need for cost-effective and minimally invasive approaches to facilitate the early detection and timely management of endometrial cancer. We analysed blood plasma samples in a cross-sectional diagnostic accuracy study of women with endometrial cancer (n = 342), its precursor lesion atypical hyperplasia (n = 68) and healthy controls (n = 242, total n = 652) using attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy and machine learning algorithms. We show that blood-based infrared spectroscopy has the potential to detect endometrial cancer with 87% sensitivity and 78% specificity. Its accuracy is highest for Type I endometrial cancer, the most common subtype, and for atypical hyperplasia, with sensitivities of 91% and 100%, and specificities of 81% and 88%, respectively. Our large-cohort study shows that a simple blood test could enable the early detection of endometrial cancer of all stages in symptomatic women and provide the basis of a screening tool in high-risk groups. Such a test has the potential not only to differentially diagnose endometrial cancer but also to detect its precursor lesion atypical hyperplasia—the early recognition of which may allow fertility sparing management and cancer prevention

Effective knowledge translation approaches and practices in Indigenous health research: A systematic review protocol

Background: Effective knowledge translation (KT) is critical to implementing program and policy changes that require shared understandings of knowledge systems, assumptions, and practices. Within mainstream research institutions and funding agencies, systemic and insidious inequities, privileges, and power relationships inhibit Indigenous peoples' control, input, and benefits over research. This systematic review will examine literature on KT initiatives in Indigenous health research to help identify wise and promising Indigenous KT practices and language in Canada and abroad. Methods: Indexed databases including Aboriginal Health Abstract Database, Bibliography of Native North Americans, CINAHL, Circumpolar Health Bibliographic Database, Dissertation Abstracts, First Nations Periodical Index, Medline, National Indigenous Studies Portal, ProQuest Conference Papers Index, PsycInfo, Social Services Abstracts, Social Work Abstracts, and Web of Science will be searched. A comprehensive list of non-indexed and grey literature sources will also be searched. For inclusion, documents must be published in English; linked to Indigenous health and wellbeing; focused on Indigenous people; document KT goals, activities, and rationale; an

The UK INFINITY study - early experience and complications of a multicenter series of 504 total ankle arthroplasties.

Introduction/Purpose: This is the first report from the UK INFINITY study. This is a multicentre, non-inventor, prospective observational study of 504 INFINITY fixed bearing total ankle arthroplasties. We report our early experience, complications, radiographic and functional outcomes of this prosthesis. Methods: Patients were recruited from 11 specialist centres between June 2016 and November 2019. Demographic, radiographic, and functional outcome data (Ankle Osteoarthritis Scale, Manchester Oxford Questionnaire and Euroquol 5D-5L) were collected preoperatively, at 6 months (454 patients), 1 year (328 patients) and 2 years (104 patients). The average age was 67.8 (range 23.9 to 88.5) and average BMI 29.9 (18.9 to 48.0). The COFAS grading system was used to stratify deformity. There were 259 (51.4%) COFAS Type 1, 122 (24.2%) COFAS Type 2, 32 (6.3%) COFAS 3 and 87 (17.3%) COFAS type 4. 38 patients (7.54%) presented with inflammatory arthritis. 101 (20.0%) of implantations utilised patient specific instrumentation (Prophecy). 169 (33.5%) of patients underwent an additional procedure at the time of surgery. Early and late complications and reoperations were recorded as adverse events. Radiographs were assessed for lucencies, cysts and/or subsidence. Results: There was a significant (p<0.01) improvement across all functional outcome scores at 6 months, which was sustained at one and two years. There was no significant difference with the use of patient specific instrumentation. 167 (33.1%) underwent additional procedures at index surgery. At the latest follow up 3 implants (0.6%) have been revised. One patient at 6 weeks for deep infection, one patient at 6 months for subsidence and one patient at 18 months for loosening. There were an additional 13 reoperations (2.6%) at the latest follow up. Conclusion: The UK INFINITY study is the largest reported multicentre study of a Total Ankle Arthroplasty to date. This study has shown a low early revision rate and high functional outcomes of the INFINITY prosthesis

Visually induced dizziness in children and validation of the Pediatric Visually Induced Dizziness Questionnaire

AIMS: To develop and validate the Pediatric Visually Induced Dizziness Questionnaire (PVID) and quantify the presence and severity of visually induced dizziness (ViD), i.e., symptoms induced by visual motion stimuli including crowds and scrolling computer screens in children. METHODS: 169 healthy (female n = 89; recruited from mainstream schools, London, UK) and 114 children with a primary migraine, concussion, or vestibular disorder diagnosis (female n = 62), aged 6–17 years, were included. Children with primary migraine were recruited from mainstream schools while children with concussion or vestibular disorder were recruited from tertiary balance centers in London, UK, and Pittsburgh, PA, USA. Children completed the PVID, which assesses the frequency of dizziness and unsteadiness experienced in specific environmental situations, and Strength and Difficulties Questionnaire (SDQ), a brief behavioral screening instrument. RESULTS: The PVID showed high internal consistency (11 items; α = 0.90). A significant between-group difference was noted with higher (i.e., worse) PVID scores for patients vs. healthy participants (U = 2,436.5, z = −10.719, p < 0.001); a significant difference was noted between individual patient groups [χ2(2) = 11.014, p = 0.004] but post hoc analysis showed no significant pairwise comparisons. The optimal cut-off score for discriminating between individuals with and without abnormal ViD levels was 0.45 out of 3 (sensitivity 83%, specificity 75%). Self-rated emotional (U = 2,730.0, z = −6.169) and hyperactivity (U = 3,445.0, z = −4.506) SDQ subscale as well as informant (U = 188.5, z = −3.916) and self-rated (U = 3,178.5, z = −5.083) total scores were significantly worse for patients compared to healthy participants (p < 0.001). CONCLUSION: ViD is common in children with a primary concussion, migraine, or vestibular diagnosis. The PVID is a valid measure for identifying the presence of ViD in children and should be used to identify and quantify these symptoms, which require specific management incorporating exposure to optokinetic stimuli

Proteomic analysis of malignant and benign endometrium according to obesity and insulin resistance status using Reverse Phase Protein Array

Obesity and hyperinsulinemia are known risk factors for endometrial cancer, yet thebiological pathways underlying this relationship are incompletely understood. Thisstudy investigated protein expression in endometrial cancer and benign tissue andits correlation with obesity and insulin resistance.One hundred and seven women undergoing hysterectomy for endometrial canceror benign conditions provided a fasting blood sample and endometrial tissue. Weperformed proteomic expression according to body mass index, insulin resistance,and serum marker levels. We used linear regression and independentttest for statis-tical analysis. Proteomic data from 560 endometrial cancer cases from The CancerGenome Atlas (TCGA) databank were used to assess reproducibility of results.One hundred and twenty seven proteins were significantly differentially expressedbetween 66 cancer and 26 benign patients. Protein expression involved in cellcycle progression, impacting cytoskeletal dynamics (PAK1) and cell survival (Rab25), were most significantly altered. Obese women with cancer had increasedPRAS40_pT246; a downstream marker of increased PI3K-AKT signaling. Obesewomen without cancer had increased mitogenic and antiapoptotic signaling byway of upregulation of Mcl-1, DUSP4, and Insulin Receptor-b.This exploratory study identified a number of candidate proteins specific to endo-metrioid endometrial cancer and benign endometrial tissues. Obesity and insulinresistance in women with benign endometrium leads to specific upregulation ofproteins involved in insulin and driver oncogenic signaling pathways such as thePI3K-AKT-mTOR and growth factor signaling pathways which are mitogenic andalso disruptive to metabolism.

Immediate referral to colposcopy vs. cytological surveillance for low-grade cervical cytological abnormalities in the absence of HPV test: A systematic review and a meta-analysis of the literature

We performed a systematic review and meta-analysis to explore the optimum management strategy for women with atypical squamous cells of undetermined significance (ASCUS/borderline) or low-grade squamous intra-epithelial lesions (LSIL/mild dyskaryosis) cytological abnormalities at primary screening in the absence of HPV DNA test. We searched MEDLINE, EMBASE and CENTRAL and included randomised controlled trials comparing immediate colposcopy to cytological surveillance in women with ASCUS/LSIL. The outcomes of interest were occurrence of different histological grades of cervical intra-epithelial neoplasia (CIN) and default rates during follow-up. Pooled risk ratios (RR) and 95% confidence intervals (CI) were calculated using a random-effect model and with inverse variance weighting. Interstudy heterogeneity was assessed using I2 statistics. Six RCTs were included. Immediate colposcopy significantly increased detection of unimportant abnormalities as opposed to repeat cytology (koilocytosis:32% vs.21%, RR:1.49, 95%CI=1.17-1.90); CIN1:21% vs.8%, RR:2.58, 95%CI=1.69-3.94). Although immediate colposcopy detected CIN2, CIN2+ and CIN3+ earlier than cytology, the differences were no longer observed at 24 months (CIN3+:10.3 vs.11.9%, RR:1.02, 95%CI=0.53-1.97), with significant inters-study heterogeneity (p<0.001,I2=93%). Default risk was significantly higher for repeat cytology (6months: 6.3 vs.13.3%, RR:3.85, 95%CI=1.27-11.63; 12months: 6.3 vs.14.8%, RR:6.39, 95%CI=1.24-32.95; 24 months: 0.9 vs.16.1%, RR:19.1,95%CI=9.02-40.4). Detection of CIN2+ for cytological surveillance over two years is similar to that of immediate colposcopy, although patients may default. Colposcopy may be first choice when good compliance is not assured, but may increase detection of insignificant lesions. This emphasizes the need for a reflex triage test to distinguish women who need diagnostic work-up from those who can return to routine recall

Tobacco Related Attitudes and Behaviours in Relation to Exposure to the Tackling Indigenous Smoking Program: Evidence from the Mayi Kuwayu Study

Smoking is the leading contributor to the burden of disease and mortality for Aboriginal and Torres Strait Islander peoples, with an estimated 37% of all Aboriginal and Torres Strait Islander deaths attributed to smoking. The Tackling Indigenous Smoking (TIS) program was implemented to support people to quit smoking, prevent initiation, and reduce exposure to second-hand smoke. Analysis of baseline (2018–2020) data from a large-scale cohort study was conducted to quantify smoking-related attitudes and behaviours among Aboriginal and Torres Strait Islander adults, overall and in relation to exposure to the TIS program. Most results were similar for TIS and non-TIS, but there was a significantly lower prevalence of smoking inside households (PR0.85; 95% CI: 0.74, 0.97), smoking ≥21 cigarettes per day (PR0.79; 95% CI: 0.62, &lt;1.00), and smoking a first cigarette within 5 min of waking (PR0.87; 95% CI: 0.76, &lt;1.00) in TIS-funded compared to non-TIS-funded areas. Findings from the analysis highlight encouraging anti-smoking attitudes and behaviours across TIS-funded and non-TIS-funded areas, and serve as a basis for future analysis of change in outcomes over time associated with exposure to a large multi-mode population health program (TIS)
