The early COVID-19 pandemic period and associated gestational weight gain.

The aim of this study was to investigate if gestational weight gain was altered during the early COVID-19 pandemic period. This a retrospective cohort study evaluating gestational weight gain among individuals delivering during the early COVID-19 pandemic epoch (March 10-December 31,2020) compared to temporally matched pre-pandemic (matched months in 2018 and 2019) controls using electronic medical record data from a large tertiary care hospital. The primary outcome was gestational weight gain defined as a categorical measure representing below, meeting, or above Institute of Medicine (IOM) criteria with further adjustment for gestational age at delivery. The early-pandemic exposure group was also categorized by gestational age at the start period (<14weeks' and 14-20weeks') to assess if duration of exposure affected gestational weight gain risks with the use of multinominal logistic regression. Among 5,377 individuals 3,619 (67.3 %) and 1,758 (32.7 %) were in the pre and early pandemic epochs respectively. Overall, 934 (17.4 %) individuals gained below recommended, 1,280 (23.8 %) met recommendations, and 3,163 (58.8 %) gained above IOM recommended gestational weight gain. Compared to the pre-pandemic epoch, the early pandemic period was not associated with weight gain below (OR 1.06, 95 % Cl 0.89-1.27) or above (OR 1.03, 95 % Cl 0.89-1.19) IOM recommendations. This was also true when the early pandemic group was stratified based on gestational age at the start of the early pandemic period (<14weeks' and 14-20weeks'). This study demonstrated no significant difference in maternal weight gain between pre and early COVID-19 pandemic periods.

Comparing Pain Outcomes and Treatment Adherence Between In-Person and Virtual Interdisciplinary Pain Rehabilitation Programs at the San Francisco VA Health Care System.

This study compares clinical pain outcomes between patients in a pain treatment program that was conducted in-person, compared to a virtual program. In-Person (N=127) and Virtual (N=101) pain treatment programs were compared based on patient-reported, practitioner-collected, and medical record data. The patients were measured at baseline and post treatment (week 12 for In-Person and week 8 for Virtual patients). We employed last observation carried forward (LOCF) to handle missing data. Both the In-Person and Virtual groups were similar in regard to all baseline outcomes, except the In-Person group having significantly more co-morbidities at baseline, with particularly more cases of mental, behavioral, or neurodevelopmental diseases. Both groups demonstrated significant improvements in the pain-related measurements of pain interference and pain catastrophizing thoughts, but neither group displayed a change in average pain across treatment. Further, both groups improved significantly on emotional well-being scores, but not on physical functioning scores. No significant differences existed between groups on outcomes, except for pain catastrophizing, which was higher in the Virtual group at both time points. The Virtual group had lower rates of dropouts compared to In-Person, while the In-Person group had a larger proportion reach a clinically meaningful change in pain-related outcomes, defined as a >30% improvement. While some changes were unique to the In-Person program, overall, patients in the Virtual program achieved similar treatment outcomes, suggesting that it can successfully treat Veterans seeking pain management, with less need for in-person facilities for both patients and clinicians.

Emergency department visits, inpatient hospitalizations, and non-fatal and fatal drug overdoses during COVID-19 among Veterans with opioid use disorder.

The COVID-19 pandemic had dramatic adverse impacts on people with opioid use disorder (OUD), as evidenced by significant disruptions to care and unprecedented increases in drug overdoses. In this study, we evaluated the impacts of COVID-19 on utilization of emergency and inpatient care, and fatal and non-fatal overdoses among veterans with OUD. We used Veterans Health Administration (VHA) electronic medical record and mortality data to compare emergency department (ED) visits, inpatient hospitalizations, and fatal and non-fatal overdoses between a pandemic-exposed cohort of veterans with OUD observed both pre- and post-pandemic onset (n = 53,803; observed January 2019-March 2021) to a matched pre-pandemic control group (n = 53,803; observed October 2017-December 2019). Compared to pre-pandemic trends, there were significant decreases in the odds of ED and inpatient admissions and total number of ED and inpatient admissions during COVID-19. There was a significant decrease in the odds of having a recorded non-fatal overdose. The odds of overdose death increased during the pandemic compared to pre-pandemic trends. We observed significant decreases in the utilization of ED and inpatient care services, and fewer non-fatal overdoses, post-pandemic onset. Healthcare disruptions limiting access to emergency and inpatient care could account for the lower number of recorded non-fatal overdoses, potentially reflecting an underestimate of risk. In contrast, fatal overdoses increased during the pandemic compared to pre-pandemic trends. Lower utilization of emergency and inpatient care, and higher rates of fatal overdoses during the pandemic, suggest an exacerbation of unmet treatment need post-pandemic onset.

The influence of pregnant women's anxiety levels on fetal well-being and pregnancy complications: A cross-sectional study in Lombok, Indonesia

Pregnant women are a vulnerable group who are at risk of experiencing physiological changes that result in a partial decrease in immunity. Pregnancy with anxiety for pregnant women, which can affect maternal health, hinder development, cause emotional disturbances at birth, and even result in pregnancy complications. This type of research is observational-analytic with a cross-sectional design from January to June 2021. The population in this study is all third-trimester pregnant women at the Mataram City Regional Health Center and West Lombok Regency. There were 228 respondents in the study, taken using the accidental sampling technique. Data collection was carried out by accessing medical record data and filling out questionnaires for pregnant women who underwent examinations. The results of the chi square test showed that there was a relationship between anxiety and pregnancy complications with a p value of 0.0000 (p &lt; 0.05) and a relationship between anxiety and fetal heart rate with a p value of 0.007 (p &lt; 0.05). The ANOVA test results also showed that there was a simultaneous influence of fetal heart rate and pregnancy complications on anxiety in pregnant women, with a significance value of 0.0000 (p &lt; 0.05) and an effect size of 74.6%. This research shows that early detection and management of anxiety during pregnancy is very necessary to prevent and minimize the occurrence of pregnancy complications and disruption of fetal well-being, which is characterized by an abnormal fetal heart rate.

Prevalence of gingival overgrowth among patients at the periodontology clinic of Dental Hospital Universitas Airlangga

Background: The prevalence of dental and oral health problems in Indonesia, including periodontal disease and gingival overgrowth (GO), remains high and requires serious attention from health workers. This study aims to determine the prevalence of GO due to the existing data gap and public concern regarding this condition. Objectives: To determine the prevalence of gingival overgrowth among patients at the periodontology clinic of Universitas Airlangga Dental Hospital. Material and Methods: This study was conducted from August to September 2023 at the Dental and Oral Hospital (RSGM) Universitas Airlangga using a descriptive observational method with a cross-sectional design. The sample was calculated using total sampling from medical record data of patients at the Periodontics Clinic of the Dental and Oral Hospital (RSGM) Universitas Airlangga who met the inclusion criteria in 2022. The study variables included gingival overgrowth (GO), gender, age, and tooth region (sextant). Data were processed using Microsoft Excel and presented as a percentage (%). A descriptive data analysis was carried out to draw a conclusion. Conclusion: The study found that 37.11% of patients at the Dental and Oral Hospital (RSGM) of Universitas Airlangga experienced gingival overgrowth. The percentage of male patients experiencing gingival overgrowth was higher than that of women, with the highest age group being 18-24 years. The tooth area that experienced the most gingival overgrowth was sextant 5, with a total of 29 samples.

Outcomes and Risk Factors for Morbidity and Mortality of Systemic-to-Pulmonary Shunts in a Tertiary Hospital in Thailand.

A systemic-to-pulmonary shunt is the palliation of choice for many children with cyanotic congenital heart disease. However, significant morbidity and mortality related to these procedures and the postoperative course still exists. We aim to report our outcomes of systemic-to-pulmonary shunts as well as to define certain risk factors for adverse events. We retrospectively collected data from the electronic medical records of Ramathibodi hospital from January 01, 2013, to April 30, 2024. Demographic data, operative, and postoperative details were collected and reviewed. Inclusion criteria included patients whose primary operation was a systemic-to-pulmonary shunt. Exclusion criteria were patients diagnosed with hypoplastic left heart syndrome and whose medical record data were missing significant information. There were initially 56 patients eligible for our study. After exclusion, the total number of patients enrolled was 42. Overall the results were excellent, with only one operative mortality, no discharge mortality, and four reinterventions. Outcomes between different shunt types, shunt sizes, surgical approaches, and diagnoses were statistically similar. We demonstrate that systemic-to-pulmonary shunts are a safe and reliable procedure based on our results at a tertiary hospital in Thailand. We emphasize meticulous surgical techniques as well as utilization of proper and reproducible postoperative care protocols to optimize patient outcomes.

Uniformization and bounded Taylor series in Newton-Raphsonmethod improves computational performance for a multistate transition model estimation and inference.

Multistate transition models (MSTMs) are valuable tools depicting disease progression. However, due to the complexity of MSTMs, larger sample size and longer follow-up time in real-world data, the computation of statistical estimation and inference for MSTMs becomes challenging. A bounded Taylor series in Newton-Raphson procedure is proposed which leverages the uniformization technique to derive maximum likelihood estimates and corresponding covariance matrix. The proposed method, namely uniformization Taylor-bounded Newton-Raphson, is validated in three simulation studies, which demonstrate the accuracy in parameter estimation, the efficiency in computation time and robustness in terms of different situations. This method is also illustrated using a large electronic medical record data related to statin-induced side effects and discontinuation.

23 Probing bias: Understanding the experiences of Black, Indigenous and People of Colour (BIPOC) caregivers for children with developmental disabilities and their involvement with child protection

Abstract Background In Canada and abroad, a disproportionate number of Black Indigenous and Persons of Colour (BIPOC) experience referral to child protective services (CPS). Children with developmental disabilities, including Autism Spectrum Disorders (ASD) and intellectual disabilities (IDD), are also disproportionately CPS-involved. Recent Canadian research has suggested that almost a quarter of children from a complex care paediatric program are CPS-involved, however there is no known research for ASD/IDD populations seen in a general paediatric clinic. Further, intersections of race/ethnicity and ASD/IDD and CPS involvement have not been examined. Objectives We are conducting a mixed methods study to explore the intersections of race, developmental disabilities and involvement with CPS for our paediatric population. Design/Methods Phase 1: We completed a retrospective cohort study of 349 patients (0-18 years of age) who were seen by a paediatrician and social worker at a large, hospital-based paediatric clinic in Toronto, Canada in 2019. Electronic medical record data was reviewed and the following binary variables (yes/no) coded CPS-involved or referral made, 1+ caregiver identify as BIPOC, and primary language of caregiver(s) not English. Results Preliminary analyses indicate that 11.7% of our sample is CPS-involved. Contrary to over-representation of BIPOC families in the general CPS population, we found that the proportion of families involved with CPS was lower for BIPOC than non-BIPOC families. A similar pattern was observed for primary language, with a trend towards caregivers who reported English as a second language being less likely to be CPS-involved. In our presentation, we will present analyses regarding the type and intensity of CPS involvement and include other demographic characteristics of the family. These findings will be interpreted with findings from Phase 2 (currently underway), which explores lived experiences of 40 caregivers involved with CPS drawn from Phase 1. Conclusion Within an ASD/IDD patient sample, BIPOC families were less likely to be involved with CPS than non-BIPOC families. This finding is in stark contrast to provincial rates that suggest a 2.2 times greater likelihood of CPS-involvement for Black youth. While these results on the surface suggest equity, they may still reflect bias. It is possible that the concerns of BIPOC families are being downplayed in comparison to non-BIPOC families, reducing their access to supportive services.

Role of Intraoperative Neurophysiological Monitoring in Predicting Postoperative Delirium in Patients Undergoing Carotid Endarterectomy Surgeries.

This study aims to evaluate the diagnostic utility of Electroencephalography (EEG) and Somatosensory Evoked Potentials (SSEP) as modalities of Intraoperative neurophysiological monitoring (IONM) in predicting Postoperative Delirium (POD) in patients who underwent Carotid Endarterectomy (CEA) surgery. A total cohort of 425 patients were included in this study. Medical record data was reviewed retrospectively and their documented significant IONM data were analyzed and integrated into the study for each patient. The study cohort was assessed for POD with Intensive Care Delirium Screening Checklist (ICDSC) and a score of &gt;4 was positive for delirium. Of the 425 patients that underwent CEA for carotid stenosis, 65/425 (15.29%) had documented significant IONM changes. Of those 65 patients with significant changes, 16 (24.61%) had POD. On the other hand, of the 360 patients without changes, 31 (8.61%) had POD. On performing multivariable analysis and adjusting for possible confounders, IONM changes were still significantly associated with POD (p value: &lt;0.001; 95% C.I. 1.91-7.98; OR: 3.94). Specifically, SSEP changes alone were significantly associated with POD (p value: &lt;0.001; 95% C.I. 2.36-11.08; OR: 5.15). Significant IONM changes increase the risk of developing POD in patients undergoing CEA. Despite the low overall risk of POD after CEA in our study, it is imperative to conclude that patients with POD are twice likely to exhibit changes.

Implications of Personal Data Protection Law in Consumer Health Data Management to Improve Secure and Confidential Handling in Indonesia

The purpose of this study is to understand the impact of the implementation of the Personal Data Protection Law (PDP Law) on the management of consumer health data in Indonesia, with a focus on enhancing secure and confidential handling. In the midst of the rapidly evolving digitalisation era, the management of personal data, especially those related to health information, requires strict and effective legal regulation. This is becoming increasingly urgent given the increasing incidents of data leaks and privacy violations, one of which occurred in the leak of the Indonesian Ministry of Health's server which collected 6 million patient medical record data. The research method used is normative juridical with a conceptual approach and a statutory approach, where secondary data is broken down into three different types of legal materials, namely primary, secondary, and tertiary legal materials. The PDP Law and Consumer Protection Law are the primary legal sources, accompanied by the use of relevant literature as secondary legal sources as well as dictionaries and encyclopedias as tertiary legal materials to further explain. The novelty of this research lies in the comprehensive analysis of the existing regulations and their applicability in the health context, as well as considering the increasing public awareness of their rights to personal data. The results show that although challenges such as uneven technological infrastructure and lack of awareness among health staff still exist, the measures taken through the PDP Law have created a strong foundation for better health data protection in the future, improving security and confidentiality in health data management.

Spatial and Racial/Ethnic Variation in the Prevalence of Cesarean Delivery in a South Carolina Medical Center.

While racial/ethnic disparities in cesarean delivery have been noted in the literature, less is known about the intersection between individual-level race/ethnicity and community-level social vulnerability as factors in cesarean delivery. The goal was to use medical record data from a large medical center combined with census tract-level data to examine patterns of social vulnerability, racial population distribution, and prevalence of cesarean delivery. Data were obtained from electronic medical records of patients from a large medical center in South Carolina from 2019 to 2020. The outcome variable was cesarean delivery (yes/no), and covariates included the year of delivery; age of patient; race/ethnicity; spoken language; BMI categories; clinical indications of anemia, hypertension, preeclampsia, and diabetes; and census tract Social Vulnerability Index (SVI). Generalized linear mixed models for multilevel binary logistic regression were used to test the main hypothesis that the census tract level Social Vulnerability Index is positively associated with cesarean delivery. Among a total of 5011 patients, we found that non-Hispanic Black mothers were more likely to have cesarean deliveries compared with non-Hispanic White mothers. After controlling for census tract-level SVI, the individual-level race/ethnicity association was no longer significant. Significant spatial autocorrelation across census tracts was evident for cesarean delivery prevalence, non-Hispanic Black population, and SVI. A high prevalence of cesarean delivery tended to cluster with high SVI and a high non-Hispanic Black population. We found that non-Hispanic Black mothers were more likely to have cesarean deliveries, which was explained by census tract differences in the SVI.

Combined detection of serum adiponectin and pregnancy-associated plasma protein A for early prediction of gestational diabetes mellitus.

Early diagnosis of gestational diabetes mellitus (GDM) reduces the risk of adverse perinatal and maternal outcomes. At present, the value of serum adiponectin (ADP) and pregnancy-associated plasma protein A (PAPP-A) in clinical practice for the diagnosis of GDM in early pregnancy is unclear. To investigate the predictive value of serum ADP and PAPP-A in GDM. The electronic medical record data of all pregnant women from Zhongshan People's Hospital from 2018 to 2021 were retrospectively collected and divided into GDM group and control group according to whether GDM occurred. ADP and PAPP-A levels of the 2 groups were detected in early pregnancy, and the related factors of GDM were analyzed by binary logistic regression analysis. Receiver operating characteristic (ROC) curves of ADP and PAPP-A in predicting GDM in the early pregnancy were plotted and their clinical predictive value was analyzed. The significance level for all statistical tests is 0.05. Compared with the non-GDM group, the ADP of the GDM group was significantly lower than that of the non-GDM group [(8.19 ± 2.24) vs. (10.04 ± 2.73)]mg/L, the difference between groups was statistically significant (P < .05), and the multiple of median (MoM) of PAPP-A was significantly lower than that of the non-GDM group (1.13 ± 0.52) versus (1.45 ± 0.61) (P < .05). Binary logistic regression analysis showed that elevated serum ADP and PAPP-A levels were negatively correlated with the subsequent development of GDM [odds ratio (OR) 95% confidence interval (95% CI)] was 0.626 (0.536, 0.816), 0.934 (0.908, 0.961), respectively, P < .05.ROC curve analysis showed that the sensitivity and specificity of ADP and PAPP-A in predicting gestational diabetes were79.1% and 58.6%, respectively, 92.7% and 73.1%, and respectively. The area under curve (AUC) is 0.755 for ADP and 0.770 for PAPP-A. The AUC of the combined detection was 0.867, both of which were higher than that of single index diagnosis, and the sensitivity and specificity of the combined detection were 0.958 and 0.853, respectively. In summary, PAPP-A and ADP levels are independent related factors affecting the occurrence of GDM. The combined detection of PAPP-A and ADP should be utilized in diagnosing GDM to improve pregnancy outcomes for pregnant women.

Plan of Care Visits: Implementation During Hospitalization and Association With 30-Day Readmissions in a Large, Integrated Health Care System.

Plan of Care of Visits (POCV), including the patient, nurse, and hospital provider were implemented across an integrated health system to improve provider-patient communication during hospitalization and patient outcomes. To assess POCV adoption after implementation, patient characteristics assosites were classified as teachsites were classified as teachsites were classified as teachsites were classified as ciated with POCV completion, and association of POCV with 30-day readmissions. This retrospective cohort study utilized electronic medical record (EMR) data of 237,430 adult patients discharged to home from 11 hospitals from January 2020 to December 2022. POCV completion was a discrete EMR variable. POCV adoption was estimated monthly by hospital as proportion of patients with at least 1 POCV during hospitalization, with variation among hospitals measured using the Variance Partition Coefficient (VPC). Multivariable logistic regressions assessed factors associated with POCV completion and POCV association with 30-day readmission. POCV adoption increased from 69% to 94% (2020-2022) and varied by 50% across hospitals (VPC 0.50, 95% CI: 0.29-0.70). Odds of a discharge-day POCV were lower among older patients (≥65 vs. 18-34y, OR 0.81, CI: 0.79-0.83), and higher among female (OR 1.06; CI: 1.04-1.07), Asian (vs. White, OR 1.13; CI: 1.06-1.21), Hispanic (OR 1.09; CI: 1.05-1.13), and surgical patients (vs. medical, OR 1.33; CI: 1.30-1.35). Patients completing discharge-day POCV had lower 30-day readmission odds (2022 OR 0.76, CI: 0.73-0.79). Patients with POCV on ≥75% of hospital days had similar readmission odds trends. POCV implementation was successful, and POCV completion was associated with fewer 30-day readmissions. Future work should focus on increasing POCV adoption while reducing hospital variation.

Enhancing Thoracic Surgery with AI: A Review of Current Practices and Emerging Trends.

Artificial intelligence (AI) is increasingly becoming integral to medical practice, potentially enhancing outcomes in thoracic surgery. AI-driven models have shown significant accuracy in diagnosing non-small-cell lung cancer (NSCLC), predicting lymph node metastasis, and aiding in the efficient extraction of electronic medical record (EMR) data. Moreover, AI applications in robotic-assisted thoracic surgery (RATS) and perioperative management reveal the potential to improve surgical precision, patient safety, and overall care efficiency. Despite these advancements, challenges such as data privacy, biases, and ethical concerns remain. This manuscript explores AI applications, particularly machine learning (ML) and natural language processing (NLP), in thoracic surgery, emphasizing their role in diagnosis and perioperative management. It also provides a comprehensive overview of the current state, benefits, and limitations of AI in thoracic surgery, highlighting future directions in the field.

Assessing Long-Term Adverse Outcomes in Older Kidney Transplant Recipients: A Propensity Score-Matched Comparison of Early Steroid Withdrawal Versus Continuous Steroid Immunosuppression Using a Large Real-World Database.

Steroids are widely used in maintenance immunosuppression treatment in kidney transplant recipients. Older individuals undergo age-related immunosenescence that consequently decreases their ability to process and evoke a response to foreign antigens. Thus, steroids may not be necessary in preventing allograft rejection and may consequently increase older recipients' risk of long-term steroid-related adverse effects. The objective of this study was to analyze the adverse outcomes of long-term steroid immunosuppression in older kidney transplant recipients using real-world electronic medical record data. The TriNetX database "US Collaborative Network" was utilized to perform a propensity score-matched case-control study comparing 1-year, 3-year, and 5-year adverse effects of steroid immunosuppression in older adults (aged ≥65 years) kidney transplant recipients who underwent either an early-steroid withdrawal (ESW) maintenance regimen or a steroid continuous immunosuppression (SCI) regimen between 31 December, 2010 and 31 December, 2020. Early-steroid withdrawal was defined as tacrolimus plus mycophenolate mofetil maintenance with no prednisone after the seventh day post-transplant. Steroid continuous immunosuppression was defined as tacrolimus plus mycophenolate mofetil plus prednisone maintenance. Cohorts were matched on age, race/ethnicity, and risk factors for adverse steroid-related outcomes and rejection. Outcomes included post-transplant diabetes mellitus, dyslipidemia osteoporosis/fractures, myocardial infarction, glaucoma/cataract, stroke, pulmonary embolism, and malignancy. Secondary outcomes analyzed incidences of infection-related outcomes, graft-related outcomes, and recipient mortality. After matching, there were 304 recipients in each group (ESW, SCI). Mean age at the time of transplant was 69.2±3.7 years (ESW) and 69.2±3.4 years (SCI, p=0.96). The Kaplan-Meier analysis showed recipients who underwent SCI had increased incidences of post-transplant diabetes mellitus at 1 year (22.36% vs 30.37%, p=0.01) and 3 years (34.89% vs 44.29%, p=0.01), but this became non-significant at 5 years post-transplant (41.97% vs 42.6%, p=0.34). Incidences of acute pancreatitis were higher for the SCI cohort at 3 years (p=0.02) as well as incidences of acute myocardial infarction at 5 years post-kidney transplant (6.75% vs 14.39%, p<0.01). No difference was found for other adverse outcomes. Early-steroid withdrawal recipients experienced significantly fewer infection-related outcomes, such as cytomegalovirus, BK virus, sepsis/bacteremia, and fungal infections, compared with SCI recipients. Last, recipients who underwent ESW experienced fewer incidences of rejection and death-censored graft failure at 5 years post-transplant. There is currently no standard maintenance immunosuppression protocol for older kidney transplant recipients. Death-censored graft survival, rejection, and patient survival were improved with ESW. Steroid minimization may be beneficial in this population given that it lowers the risk of drug-induced adverse effects.

Correlation Crossmatching Test with Effectiveness of Transfusion in Hemolytic Anemia Patients

Hemolytic anemia is anemia caused by the premature destruction of red blood cells. Transfusion with hemolytic anemia is a dilemmatic indication and is still based on clinical decisions. Several studies assessed the effectiveness of transfusions in hemolytic anemia patients with incompatible crossmatching showed effectiveness. This study aimed to analyze crossmatching with transfusion effectiveness in hemolytic anemia patients. Retrospective cohort observational study with medical record data from January 2019 to May 2022 of hemolytic anemia patients who got transfusion therapy. The variables included age, gender, hemoglobin levels before and after transfusion, crossmatching test, and transfusion effectiveness based on increased hemoglobin after transfusion 1 g/dL of 1 Pack Red Cell (PRC) unit. One hundred three (103) patients with hemolytic anemia 45 received PRC, 12 males (26.7%) and 33 females (73.3%). Ages 19 - &lt; 45 years subjects had the most transfusions. Hemoglobin levels before and after transfusion showed significant differences (p-value =0.000) in the patients with a diagnosis of hereditary, unspecified, and autoimmune hemolytic anemias. The correlation between the effectiveness of transfusions with gender and age was not found (p=0.521, p=0.240). The correlation between crossmatching with the effectiveness of transfusion was not found (p=0.089). Hemolytic anemia patients with transfusion showed an increase in hemoglobin levels between before and after transfusion even with incompatible crossmatching. The correlation between the results of crossmatching with transfusion effectiveness in patients with hemolytic anemia was not found. Good premedication treatment can provide effective transfusion.

Antibiotic Susceptibility among Infective Endocarditis Population: Syndromic Antibiogram Evaluation at Indonesian National Cardiovascular Center

Infective Endocarditis (IE) is a life-threatening disease with a high mortality rate (25%). Laboratory approaches to support the diagnosis of IE especially blood and/or cardiac vegetation culture, are crucial for providing definitive therapy. However, negative culture is frequently observed, therefore empirical use of antibiotics seems unavoidable and may lead to increasing antimicrobial resistance. This study aims to observe the prevalence of antibiotic susceptibility among the IE population using the WISCA approach. This retrospective study observed medical record data of all inpatients diagnosed with IE according to ICD-10 at Cardiovascular Center Harapan Kita Hospital (NCCHK) between January 2018 and December 2022. Patient data were combined with bacterial identification and antibiotic susceptibility test data from the laboratory information system, and evaluated based on period (year). A total of 67,858 inpatients and 1.1% (n=772) were diagnosed with IE. Successful culture growth (blood and/or cardiac vegetation specimen) was between 36.8% and 70% annually. Streptococcus viridans group (82/237, 34.6%) and Coagulase-negative Staphylococci (57/237, 24.1%) were dominantly observed among the IE population. Low susceptibility among Penicillin (34.3%) towards Gram-positive bacteria, as first-line treatment option in IE. Meanwhile, high susceptibility range was observed in Ceftriaxone (95.7%), Gentamicin (80.4%), Rifampicin (84.4%), and Vancomycin (98.7%) as second-line treatment in IE. Despite the low prevalence, the occurrence of antimicrobial resistance in IE has become a priority concern. Continuing the syndromic antibiogram is mandatory to assist the trend of empirical antibiotic usage and refine the established local treatment guidelines.

NPM1 Minimal Residual Disease Detection at Any Time by Clinical Next Generation Sequencing Predicts Poor Survival in Acute Myeloid Leukemia

Abstract Introduction/Objective Acute Myeloid Leukemia (AML) is a deadly disease that accounts for 80% of adult leukemia cases and carries a 5-year survival rate of only 31.7%. Historically, prognosis hinged heavily on cytogenetic stratification, but more recently minimal residual disease (MRD) has emerged as a crucial prognostic marker. Flow cytometry, PCR, and NGS can all be employed for MRD detection, but each carries its own limitations. Though technically challenging, NGS has the advantage being able to simultaneously assay multiple mutations, thus providing for broader applicability. NPM1 is the most prevalently mutated gene in AML (25-35%). In this study, one of the largest of its kind, we investigate the feasibility and impact of NPM1 MRD detection by clinical NGS. Methods/Case Report IRB approval was obtained. We reviewed the medical record and clinical laboratory data sets from AML patients treated at Moffitt Cancer Center who had NPM1 status assessed by clinical NGS, Testing was performed at LabPMM (San Diego, CA). DNA was extracted, and NPM1 exon 12 was amplified. PCR products were sequenced on an Illumina MiSeq. The clinically reportable assay sensitivity was 5 x 10-5 though lower levels were detected on review of raw data. Kaplan-Meier analysis was conducted for overall survival assessment. Since patients often had multiple tests, we divide patients into those with NPM1+ at any time and NPM1 always negative. Results (if a Case Study enter NA) There was a total of 140 patients. Overall, 346 tests were conducted, with an average of 2.5 tests/patient. There were 85 patients (60%) who underwent serial testing. MRD+ patients (n=80) had a mean age of 66 years, while MRD- patients (n=60) had a mean age of 58 years. MRD+ patients exhibited a mean overall survival of 29.3 months versus 43.6 months for MRD- patients (p=0.005.) Conclusion Through our study encompassing a large patient cohort of 140 patients and nearly 350 testing data points, we confirm the feasibility and clinical utility of NPM1 MRD evaluation by NGS. The significantly poorer survival in patients who were MRD+ at any time during their disease provides a scientific rationale for serial NGS testing to enable risk stratification of NPM1+ AML patients.

Evaluation of autoimmune neurology testing clinical utility and stewardship initiatives

Abstract Testing for neural autoantibodies associated with autoimmune neurological diseases has an important role in clinical care. However, as they are niche tests for relatively rare diseases, they often have longer turn-around-times and more expensive costs than many other laboratory tests. In addition, due to the low yield of positive results, they often appear as attractive stewardship targets. Our objective was to review current utilization and ordering patterns and evaluate the impact of ongoing stewardship efforts to inform next steps regarding stewardship of these tests. Methods: Data on utilization and ordering patterns of autoimmune and paraneoplastic neural autoantibody panels from January 1 to December 31, 2023, was obtained from reference laboratory and electronic medical record (EMR) data. Additional data on best practice advisories from the most recent six months was obtained from the EMR. Results: Overall, we observed that providers tested 2270 patients both from our defined test menu (five total tests, ~89% of total orders) and through the miscellaneous route (12 total tests, ~11% of total orders), which allows providers to place orders for tests not currently on our menu. Just under one third of the orders were in cerebrospinal fluid (CSF) (n=725), while the remaining were for serum (n=1545). The percent positivity was generally higher in serum specimens, ranging from 0 to 50% per test (n=227 total positive specimens). The percent positivity in CSF specimens ranged from 0 to 40% per test (n=29 total positive specimens), which is generally consistent with previously published literature. Most of the orders were placed by neurology providers (56%). The best practice advisories (BPAs) currently in use are soft stops that target repeat tests in the same specimen type within thirty days of a previous order. Of note, these BPAs can only catch orders placed through the defined process. In six months, the BPA for repeat serum orders fired 104 times for 42 unique patients; the BPA for repeat CSF orders fired 96 times for 38 unique patients. The serum BPA resulted in elimination of the repeat order for 43% of patients (n=18), while the CSF BPA resulted in elimination of the repeat order for 24% of patients (n=9). We observed some situations in which the BPA appeared to be firing when previous orders were incorrectly collected and so not able to be sent out. Conclusion: Based on these data, we plan three main steps to continue to refine autoimmune neurology testing: 1) update our test menu to offer the most clinically useful orders through the defined route, 2) pilot review of tests ordered through the miscellaneous route, and 3) optimize BPAs to target situations with inappropriate utilization rather than technical issues.

Associations between Systemic and Dental Diseases in Elderly Korean Population

Background and Objectives: Modernization and population aging have increased the prevalence of systemic diseases, such as diabetes and hypertension, which are often accompanied by various dental diseases. Our aim was to investigate associations between common dental conditions and major systemic diseases in an elderly Korean population. Materials and Methods: Utilizing electronic medical record data from 43,525 elderly patients, we examined the prevalence of systemic diseases (diabetes, hypertension, rheumatoid arthritis, osteoporosis, dementia) and dental conditions (caries, periodontal disease, pulp necrosis, tooth loss). The analysis focused on the correlations between these diseases. Results: Significant associations were found between systemic diseases and an increased prevalence of dental conditions. Patients with systemic diseases, especially those with multiple conditions, had higher incidences of periodontal disease and tooth loss. The correlation was particularly strong in patients with diabetes and rheumatoid arthritis. Interestingly, temporomandibular joint disorder was less frequent in this cohort. Conclusions: The findings highlight the importance of integrated dental care in managing systemic diseases in elderly populations. Enhanced dental monitoring and proactive treatment are essential due to the strong association between systemic diseases and dental conditions. Collaboration between dental and medical professionals is crucial for comprehensive care that improves health outcomes and quality of life for elderly patients.
