Diverse Community Data for Benchmarking Data Privacy Algorithms

The Diverse Communities Data Excerpts are the core of a National Institute of Standards and Technology (NIST) program to strengthen understanding of tabular data deidentification technologies such as synthetic data. Synthetic data is an ambitious attempt to democratize the benefits of big data; it uses generative models to recreate sensitive personal data with new records for public release. However, it is vulnerable to the same bias and privacy issues that impact other machine learning applications, and can even amplify those issues. When deidentified data distributions introduce bias or artifacts, or leak sensitive information, they propagate these problems to downstream applications. Furthermore, real-world survey conditions such as diverse subpopulations, heterogeneous non-ordinal data spaces, and complex dependencies between features pose specific challenges for synthetic data algorithms. These observations motivate the need for real, diverse, and complex benchmark data to support a robust understanding of algorithm behavior. This paper introduces four contributions: new theoretical work on the relationship between diverse populations and challenges for equitable deidentification; public benchmark data focused on diverse populations and challenging features curated from the American Community Survey; an open source suite of evaluation metrology for deidentified datasets; and an archive of evaluation results on a broad collection of deidentification techniques. The initial set of evaluation results demonstrate the suitability of these tools for investigations in this field

Serum Vitamin D level in sepsis patients and its correlation with clinical outcome

Background: Serum Vitamin D plays an important role in sepsis; lack of Vitamin D has been linked to a higher risk for the progression of infections, as it signifies an immune system mediator. Aims and Objectives: In this study, our aim is to evaluate the correlation between serum levels of Vitamin D and clinical outcome in sepsis patients. Materials and Methods: The present prospective cohort study was performed on patients over 18 years of age suspected of sepsis presenting to an emergency department during 1 year. For all eligible patients, the blood sample was drawn for the measurement of serum level of Vitamin D3, and its correlation with outcomes such as mortality, renal failure, and liver failure was assessed. Results: One hundred and sixty patients with a mean age of 48.5±20.587 years were studied (60.0% males). The mean serum level of Vitamin D3 in the studied patients was 32.0±12.54 ng/mL. By considering 30–100 ng/mL as the normal range of Vitamin D, 70% of the patients had Vitamin D deficiency. Only age (r=−0.261, P=0.037) and mortality (r=−0.426, P=0.025) showed a significant correlation with mean Vitamin D. Conclusion: Based on the result of this study, out of 160 patients, 61.25% of patients with sepsis are Vitamin D deficient. There is a significant and inverse relationship between mortality and advanced age which were associated with serum Vitamin D3 levels. Hence, supplementing with Vitamin D appears to have potential benefits in reducing infection rates, sepsis-related deaths, and infection prevalence, particularly in the elderly

NAFLD is a risk factor for the development of diabetic nephropathy in patients with T2DM

Background: Non-alcoholic fatty liver disease (NAFLD) and diabetes are two common health problems of global concern. Diabetic nephropathy (DN) is also a microvascular complication of diabetes. However, there is little knowledge about the relationship between NAFLD and DN. Aims and Objectives: The aim of this study was to know the association between NAFLD and DN in type 2 diabetes mellitus (T2DM) patients. Materials and Methods: A cross-sectional study was conducted on 136 patients of T2DM admitted to Sanjay Gandhi memorial Hospital, Rewa. Using abdominal ultrasonography, patients were grouped as patients, with NAFLD and patients without NAFLD. Then, patients were screened for DN (microalbuminuria) using the dipstick method. Liver and kidney function tests and complete blood count were performed along with FBS, PPBS, and HbA1c. Data were analyzed by appropriate statistical tests by Wizard 2® (Version 2.0.12 (259)) software. P<0.05 was considered significant. Results: In this study, 61 (44.85%) patients were found to have NAFLD, and 30 (49.81%) also had DN. Out of 75 (55.14%) non-NAFLD patients, 21 (28%) had DN. The data were statistically significant (OR: 2.4885, 95%, P=0.0120). The mean estimated glomerular filtration rate (eGFR) (mL/min/1.73 m2) among subjects with FIB4 score ≥2.67 was 77.33±9.54 and was less as compared to the mean eGFR among subjects with FIB4 score <2.67 (104.12±5.23) (student t-test, t (134)=2.247, P=0.026). Conclusion: NAFLD might be a risk factor for the development of DN in T2DM patients

Rehabilitation versus surgical reconstruction for non-acute anterior cruciate ligament injury (ACL SNNAP): a pragmatic randomised controlled trial

BackgroundAnterior cruciate ligament (ACL) rupture is a common debilitating injury that can cause instability of the knee. We aimed to investigate the best management strategy between reconstructive surgery and non-surgical treatment for patients with a non-acute ACL injury and persistent symptoms of instability.MethodsWe did a pragmatic, multicentre, superiority, randomised controlled trial in 29 secondary care National Health Service orthopaedic units in the UK. Patients with symptomatic knee problems (instability) consistent with an ACL injury were eligible. We excluded patients with meniscal pathology with characteristics that indicate immediate surgery. Patients were randomly assigned (1:1) by computer to either surgery (reconstruction) or rehabilitation (physiotherapy but with subsequent reconstruction permitted if instability persisted after treatment), stratified by site and baseline Knee Injury and Osteoarthritis Outcome Score—4 domain version (KOOS4). This management design represented normal practice. The primary outcome was KOOS4 at 18 months after randomisation. The principal analyses were intention-to-treat based, with KOOS4 results analysed using linear regression. This trial is registered with ISRCTN, ISRCTN10110685, and ClinicalTrials.gov, NCT02980367.FindingsBetween Feb 1, 2017, and April 12, 2020, we recruited 316 patients. 156 (49%) participants were randomly assigned to the surgical reconstruction group and 160 (51%) to the rehabilitation group. Mean KOOS4 at 18 months was 73·0 (SD 18·3) in the surgical group and 64·6 (21·6) in the rehabilitation group. The adjusted mean difference was 7·9 (95% CI 2·5–13·2; p=0·0053) in favour of surgical management. 65 (41%) of 160 patients allocated to rehabilitation underwent subsequent surgery according to protocol within 18 months. 43 (28%) of 156 patients allocated to surgery did not receive their allocated treatment. We found no differences between groups in the proportion of intervention-related complications.InterpretationSurgical reconstruction as a management strategy for patients with non-acute ACL injury with persistent symptoms of instability was clinically superior and more cost-effective in comparison with rehabilitation management

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Assessment of Macrovascular Compilations in Type 2 Diabetes Mellitus Patients with Special Reference to Platelet Indices

Introduction:Diabetes mellitus (DM) is not a single disease entity but rather a group of metabolic disorders sharing the common underlying features of hyperglycemia. Larger and younger size of the platelets are suggestive of increased risk of thrombosis and also associated with increased risk for hyperglycemic complication.Objective:To assess correlation of macrovascular complications in T2DM patients with special reference toplatelet indices(MPV).Material and method: Acrosssectional analytical study was carried out in our institution for Total of 500 subjects was enrolled in the study and presence of macrovascular complications was noted. Result:MPV is significantly higher in patients with poor glycemic control(HbA1c&gt;7)and presence of macrovascular complications compared to patients with good glycemic control (HbA1c≤7) and absence of macrovascular complications(pvalue is&lt;0.05which is highly significant).Conclusion:Our study showed that changes in platelet indices were found to be associated with T 2 diabetes mellitus and its macrovascular complication.Hence MPVcan be used as a simple and cost effective indicator to find the association between T2 diabetes mellitus and its macrovascular complication

Antecolic Laparoscopic Roux-en-Y Gastric Bypass is not Associated with Higher Complication Rates

Since its introduction in 1994, laparoscopic Roux- en-Y gastric bypass (LRYGB) has rapidly gained popularity for the treatment of morbid obesity. Historically, the operation is performed in a retrocolic fashion; however antecolic LRYGB has been advocated as a safe alternative. We reviewed our experience with both techniques. From January 2003 to November 2004, the new UCLA Laparoscopic Bariatric Surgery Program performed 341 LRYGBs. In March 2004, our program transitioned from a retrocolic to an antecolic approach for all gastric bypass procedures. Institutional review board approval was obtained, and the data for all patients was collected into a prospective database. The patient characteristics for the two groups were similar. The significant differences between the two groups were average body mass index and the percentage of patients with diabetes and sleep apnea. The complication profiles for the two groups were also similar. There were significant differences between the two groups in the reoperation rate, antecolic 2.0 per cent versus retrocolic 7.8 per cent, and length of stay, antecolic 2.57 versus retrocolic 2.89 days. There were no anastomotic leaks or deaths in either group. Antecolic LRYGB is safe and may be associated with fewer complications. Only long-term weight loss results and complication rates will provide a definitive answer. </jats:p
