How successful is commercial DNA testing in resolving British & Irish cases of unknown parentage?

This study is the first to characterise the type of people trying to resolve unknown parentage cases in the UK and Ireland, and how successful their efforts are, using commercial DTC (direct-to-consumer) DNA tests. A survey was conducted of individuals born in the UK or Ireland, or with a biological parent from the UK or Ireland, who had used genetic genealogy as a part of their search for one or both biological parents. Success rates were high with DNA assisting the identification of a birth parent in 48-55% of cases. In an additional 20-21% of cases, DNA identified grandparents or more distant ancestors. The majority of those identifying a biological parent did so within 6 months of receiving their DNA results (39-55% of cases), and within 2 years, 78-87%% had identified a biological parent. When they first got their results, 40% had very close matches (half-first cousin or closer), an additional 33% had close matches in the second cousin range, and the remaining 27% had more distant matches. The survey also attempted to assess the likelihood of success of the combined use of GEDmatch and FTDNA in IGG (investigative genetic genealogy) cases in Britain and Ireland and found that potentially IGG-suitable matches were present in about 60% of cases. These results complement those of earlier studies and have important implications for social policy in the UK and Ireland

The Cyclical Relationship Between Generational Poverty and Poor Education: Breaking the Barrier in Haiti

Research demonstrates that generational poverty and poor education are cyclical in nature. In Haiti, poverty diminishes the quality of education due to the fact it hampers access to education, lacks parental involvement, and has inadequate health care. Conversely, poor education traps Haitians in the cycle of generational poverty by inhibiting them from developing life skills and adequate literacy; in turn, this disables them from participating in higher paying jobs. Based on the repetitive correspondence between the two, our goals are: to educate individuals on the cyclical relationship between poor education and generational poverty, expose and examine the barriers to receiving an education, as well as suggest ways to overcome the barriers against education federally and individually

Overview of Australian Aboriginal and Torres Strait Islander health status 2016

This report provides a comprehensive overview of the most recent indicators of the health and wellbeing of Aboriginal and Torres Strait Islander people. Information focuses on: Aboriginal and Torres Strait Islander populations the context of Aboriginal and Torres Strait Islander health various measures of population health status selected health conditions health risk and protective factors. The Overview shows that the health of Aboriginal and Torres Strait Islander people continues to improve slowly and there has been a decline in the death rates for Aboriginal and Torres Strait Islander people and also a significant closing of the gap in death rates between Aboriginal and Torres Strait Islander and non-Indigenous people. The infant mortality rate has declined significantly. There have also been improvements in a number of areas contributing to health status such as the proportion of Aboriginal and Torres Strait Islander mothers who smoked during pregnancy has decreased. There has been a slight decrease in the proportion of low birth weight babies born to Aboriginal and Torres Strait Islander mothers between 2004 and 2014. Age-standardised death rates for respiratory disease in NSW, Qld, WA, SA and NT declined by 26% over the period 1998-2012 for Aboriginal and Torres Strait Islander people. Two new sections are featured in this edition of the Overview. With the 20th anniversary of the Bringing them home report, a section has been dedicated to Healing which highlights the contribution of healing workers and organisations to supporting people, families and communities impacted by the Stolen Generations. Environmental health with its important link to the social determinants of health is also included for the first time in the Overview 2016

Differential associations of cystatin C versus creatinine‐based kidney function with risks of cardiovascular event and mortality among South Asian individuals in the UK Biobank

Background: South Asian individuals have increased cardiovascular disease and mortality risks. Reliance on creatinine‐ rather than cystatin C–based estimated glomerular filtration rate (eGFRcys) may underestimate the cardiovascular disease risk associated with chronic kidney disease. Methods and Results: Among 7738 South Asian UK BioBank participants without prevalent heart failure (HF) or atherosclerotic cardiovascular disease, we investigated associations of 4 eGFRcys and creatinine‐based estimated glomerular filtration rate categories (<45, 45–59, 60–89, and ≥90 mL/min per 1.73 m2) with risks of all‐cause mortality, incident HF, and incident atherosclerotic cardiovascular disease. The mean age was 53±8 years; 4085 (53%) were women. Compared with creatinine, cystatin C identified triple the number of participants with estimated glomerular filtration <45 (n=35 versus n=113) and 6 times the number with estimated glomerular filtration 45 to 59 (n=80 versus n=481). After multivariable adjustment, the eGFRcys 45 to 59 category was associated with higher risks of mortality (hazard ratio [HR], 2.38 [95% CI, 1.55–3.65]) and incident HF (sub‐HR [sHR], 1.87 [95% CI, 1.09–3.22]) versus the eGFRcys ≥90 category; the creatinine‐based estimated glomerular filtration rate 45 to 59 category had no significant associations with outcomes. Of the 7623 participants with creatinine‐based estimated glomerular filtration rate ≥60, 498 (6.5%) were reclassified into eGFRcys <60 categories. Participants who were reclassified as having eGFRcys <45 had higher risks of mortality (HR, 4.88 [95% CI, 2.56–9.31]), incident HF (sHR, 4.96 [95% CI, 2.21–11.16]), and incident atherosclerotic cardiovascular disease (sHR, 2.29 [95% CI, 1.14–4.61]) versus those with eGFRcys ≥90; those reclassified as having eGFRcys 45 to 59 had double the mortality risk (HR, 2.25 [95% CI, 1.45–3.51]). Conclusions: Among South Asian individuals, cystatin C identified a high‐risk chronic kidney disease population that was not detected by creatinine and enhanced estimated glomerular filtration rate–based risk stratification for mortality, incident HF, and incident atherosclerotic cardiovascular disease

Assessment of Cystatin C level for risk stratification in adults with chronic kidney disease

Importance: Kidney function is usually estimated from serum creatinine level, whereas an alternative glomerular filtration marker (cystatin C level) associates more closely with future risk of cardiovascular disease (CVD) and mortality. Objectives: To evaluate whether testing concordance between estimated glomerular filtration rates based on cystatin C (eGFRcys) and creatinine (eGFRcr) levels would improve risk stratification for future outcomes and whether estimations differ by age. Design, Setting, and Participants: A prospective population-based cohort study (UK Biobank), with participants recruited between 2006-2010 with median follow-up of 11.5 (IQR, 10.8-12.2) years; data were collected until August 31, 2020. Participants had eGFRcr greater than or equal to 45 mL/min/1.73 m2, albuminuria (albumin <30 mg/g), and no preexisting CVD or kidney failure. Exposures: Chronic kidney disease status was categorized by concordance between eGFRcr and eGFRcys across the threshold for hronic kidney disease (CKD) diagnosis (60 mL/min/1.73 m2). Main Outcomes and Measures: Ten-year probabilities of CVD, mortality, and kidney failure were assessed according to CKD status. Multivariable-adjusted Cox proportional hazards models tested associations between CVD and mortality. Area under the receiving operating curve tested discrimination of eGFRcr and eGFRcys for CVD and mortality. The Net Reclassification Index assessed the usefulness of eGFRcr and eGFRcys for CVD risk stratification. Analyses were stratified by older (age 65-73 years) and younger (age <65 years) age. Results: There were 428 402 participants: median age was 57 (IQR, 50-63) years and 237 173 (55.4%) were women. Among 76 629 older participants, there were 9335 deaths and 5205 CVD events. Among 351 773 younger participants, there were 14 776 deaths and 9328 CVD events. The 10-year probability of kidney failure was less than 0.1%. Regardless of the eGFRcr, the 10-year probabilities of CVD and mortality were low when eGFRcys was greater than or equal to 60 mL/min/1.73 m2; conversely, with eGFRcys less than 60 mL/min/1.73 m2, 10-year risks were nearly doubled in older adults and more than doubled in younger adults. Use of eGFRcys better discriminated CVD and mortality risk than eGFRcr. Across a 7.5% 10-year risk threshold for CVD, eGFRcys improved case Net Reclassification Index by 0.7% (95% CI, 0.6%-0.8%) in older people and 0.7% (95% CI, 0.7%-0.8%) in younger people; eGFRcr did not add to CVD risk estimation. Conclusions and Relevance: The findings of this study suggest that eGFRcr 45 to 59 mL/min/1.73 m2 includes a proportion of individuals at low risk and fails to capture a substantial proportion of individuals at high-risk for CVD and mortality. The eGFRcys appears to be more sensitive and specific for CVD and mortality risks in mild CKD

Cystatin C- and creatinine-based estimated GFR differences: prevalence and predictors in the UK Biobank

Rationale & objective: Large differences between estimated glomerular filtration rate (eGFR) based on cystatin C (eGFRcys) and creatinine (eGFRcr) occur commonly. A comprehensive evaluation of factors that contribute to these differences is needed to guide the interpretation of discrepant eGFR values. Study design: Cohort study. Setting & participants: 468,969 participants in the UK Biobank. Exposures: Candidate sociodemographic, lifestyle factors, comorbidities, medication usage, and physical and laboratory predictors. Outcomes: eGFRdiff, defined as eGFRcys minus eGFRcr, categorized into 3 levels: lower eGFRcys (eGFRdiff, less than -15 mL/min/1.73 m2), concordant eGFRcys and eGFRcr (eGFRdiff, -15 to < 15 mL/min/1.73 m2), and lower eGFRcr (eGFRdiff, ≥15 mL/min/1.73 m2). Analytical approach: Multinomial logistic regression models were constructed to identify predictors of lower eGFRcys or lower eGFRcr. We developed 2 prediction models comprising 375,175 participants: (1) a clinical model using clinically available variables and (2) an enriched model additionally including lifestyle variables. The models were internally validated in an additional 93,794 participants. Results: Mean ± standard deviation of eGFRcys was 88 ± 16 mL/min/1.73 m2, and eGFRcr was 95 ± 13 mL/min/1.73 m2; 25% and 5% of participants were in the lower eGFRcys and lower eGFRcr groups, respectively. In the multivariable enriched model, strong predictors of lower eGFRcys were older age, male sex, South Asian ethnicity, current smoker (vs never smoker), history of thyroid dysfunction, chronic inflammatory disease, steroid use, higher waist circumference and body fat, and urinary albumin-creatinine ratio >300 mg/g. Odds ratio estimates for these predictors were largely inverse of those in the lower eGFRcr group. The model's area under the curve was 0.75 in the validation set, with good calibration (1.00). Limitations: Limited generalizability. Conclusions: This study highlights the multitude of demographic, lifestyle, and health characteristics that are associated with large eGFRdiff. The clinical model may identify individuals who are likely to have discrepant eGFR values and thus should be prioritized for cystatin C testing

Feasibility and safety of planned early discharge following laparotomy in gynecologic oncology with enhanced recovery protocol including opioid-sparing anesthesia

ObjectiveThis study aims to evaluate the feasibility and safety of planned postoperative day 1 discharge (PPOD1) among patients who undergo laparotomy (XL) in the department of gynecology oncology utilizing a modified enhanced recovery after surgery (ERAS) protocol including opioid-sparing anesthesia (OSA) and defined discharge criteria.MethodsPatients undergoing XL and minimally invasive surgery (MIS) were enrolled in this prospective, observational cohort study after the departmental implementation of a modified ERAS protocol. The primary outcome was quality of life (QoL) using SF36, PROMIS GI, and ICIQ-FLUTS at baseline and 2- and 6-week postoperative visits. Statistical significance was assessed using the two-tailed Student's t-test and non-parametric Mann–Whitney two-sample test.ResultsOf the 141 subjects, no significant demographic differences were observed between the XL group and the MIS group. The majority of subjects, 84.7% (61), in the XL group had gynecologic malignancy [vs. MIS group; 21 (29.2%), p < 0.001]. All patients tolerated OSA. The XL group required higher intraoperative opioids [7.1 ± 9.2 morphine milligram equivalents (MME) vs. 3.9 ± 6.9 MME, p = 0.02] and longer surgical time (114.2 ± 41 min vs. 96.8 ± 32.1 min, p = 0.006). No significant difference was noted in the opioid requirements at the immediate postoperative phase and the rest of the postoperative day (POD) 0 or POD 1. In the XL group, 69 patients (73.6%) were successfully discharged home on POD1. There was no increase in the PROMIS score at 2 and 6 weeks compared to the preoperative phase. The readmission rates within 30 days after surgery (XL 4.2% vs. MIS 1.4%, p = 0.62), rates of surgical site infection (XL 0% vs. MIS 2.8%, p = 0.24), and mean number of post-discharge phone calls (0 vs. 0, p = 0.41) were comparable between the two groups. Although QoL scores were significantly lower than baseline in four of the nine QoL domains at 2 weeks post-laparotomy, all except physical health recovered by the 6-week time point.ConclusionsPPOD1 is a safe and feasible strategy for XL performed in the gynecologic oncology department. PPOD1 did not increase opioid requirements, readmission rates compared to MIS, and patient-reported constipation and nausea/vomiting compared to the preoperative phase
