Abstract Background During the early COVID-19 pandemic a large number of investigational agents were utilized due to lack of therapeutic options. We evaluate the utility of commonly-used investigational agents combined with hydroxychloroquine (HCQ). Methods This multicenter observational cohort study included patients admitted with COVID-19 between March - May 2020 in Detroit, Michigan who received at least 2 doses of HCQ. Our primary outcome was the change in Sequential Organ Failure Assessment (SOFA) score from presentation to day 5 of HCQ therapy with a secondary outcome of in-hospital mortality. Data collected included demographics, Charlson Comorbidity index (CCI), daily SOFA score, laboratory data and COVID-directed therapies. Multiple linear regressions were performed to control for potential confounders between different therapies and change in SOFA score. Results Three hundred thirty-five patients receiving HCQ were included. Patients were 62 ± 14.8 years of age, male (54%) and African-American (82%) with a mean CCI of 1.7 ± 1.9. In our cohort, 32% were admitted to the intensive care unit and 35% expired. Therapies received by more than 20% of patients in addition to HCQ included azithromycin (80%), zinc (76%) and vitamin D (29%). In our unadjusted analysis, a significant improvement in SOFA score was observed with zinc (0.76) while no significant change was observed with azithromycin (-0.46) or vitamin D (0.05). However, there was no significant change in SOFA score after adjusting for confounders for azithromycin, zinc and vitamin D. No difference in mortality was observed between the groups. Conclusion Overall, no benefit in end-organ damage or mortality was observed with the addition of azithromycin, zinc or vitamin D to HCQ. Further studies are needed to confirm this observation.

Abstract Background Laboratory data and computed tomography (CT) have been used during the COVID-19 pandemic, mainly to determine patient prognosis and guide clinical management. The aim of this study was to evaluate the association between CT findings and laboratory data in a cohort of COVID-19 patients. Methods This was an observational cross-sectional study including consecutive patients presenting to the Reggio Emilia (Italy) province emergency rooms for suspected COVID-19 for one month during the outbreak peak, who underwent chest CT scan and laboratory testing at presentation and resulted positive for SARS-CoV-2. Results Included were 866 patients. Total leukocytes, neutrophils, C-reactive protein (CRP), creatinine, AST, ALT and LDH increase with worsening parenchymal involvement; an increase in platelets was appreciable with the highest burden of lung involvement. A decrease in lymphocyte counts paralleled worsening parenchymal extension, along with reduced arterial oxygen partial pressure and saturation. After correcting for parenchymal extension, ground-glass opacities were associated with reduced platelets and increased procalcitonin, consolidation with increased CRP and reduced oxygen saturation. Conclusions Pulmonary lesions induced by SARS-CoV-2 infection were associated with raised inflammatory response, impaired gas exchange and end-organ damage. These data suggest that lung lesions probably exert a central role in COVID-19 pathogenesis and clinical presentation.

Abstract Background Even after the introduction of the Sepsis-3 definition, there is still debate on the ideal antibiotic administration time in patients with sepsis. This study was performed to evaluate the association between the timing of antibiotic administration and mortality in sepsis patients who visited the emergency room. Methods A prospective cohort study was conducted on patients who were diagnosed as sepsis with Sepsis-3 definition among patients who visited the emergency department (ED) of Korea University Ansan Hospital from September 2017 to January 2019. The timing of antibiotic administration was defined as the time in hours from ED arrival until the first antibiotic administration. Cox logistic regression analysis was used to estimate the association between time to antibiotics and 7-, 14-, and 28-day mortality. Results During the study period, a total of 251 patients were enrolled with a 7-, 14-, and 28-day mortality of 16.7%, 36.3%, and 57.4%, respectively. The median time to antibiotic administration was 247 minutes (interquartile range 72 – 202 minutes). The mean age was 72 ± 15 years old and 122 patients (48.6%) were female. The most common site of infection was respiratory infection. The timing of antibiotic administration were not associated with 7-, 14-, and 28-day mortality. Female (adjusted hazard ratio [HR] 2.06 [95% confidence interval (CI) 1.21 – 3.53]; P value = 0.008), SOFA score (aHR 1.17 [95% CI 1.05 - 1.31]; P = 0.005), and initial lactate level (aHR 1.13 [95% CI 1.05 - 1.22]; P = 0.001) increased the risk of 7-day mortality. Female (aHR 2.07 [95% CI 1.48 – 2.89]; P ≤ 0.001), Charlson comorbidity index (aHR 1.12 [95% CI 1.02 - 1.24]; P = 0.025), and initial lactate level (aHR 1.19 [95% CI 1.02 - 1.16]; P = 0.011) increased the risk of 14-day mortality. Female (aHR 1.95 [95% CI 1.50 – 2.54]; P = 0.001) increased the risk of 28-day mortality in patients with sepsis. Conclusion The timing of antibiotic administration did not increase the risk of mortality in the treatment of sepsis patients who visited ED. Rather, the SOFA score, lactate, female, and comorbidity increased the mortality associated with sepsis. Disclosures All authors: No reported disclosures.

Abstract Each year, 2.8 million older adults are treated for falls, with over 800,000 hospitalized. Evidence suggests vitamin D supplementation might reduce the risk of falls, potentially through improvements in skeletal muscle function; however, results are inconsistent. In 2013 the NIA issued a request for applications to assess the efficacy and dose-response of vitamin D supplementation for fall prevention across a range of doses and serum 25(OH)D concentrations, resulting in the funding of STURDY (Study To Understand Fall Reduction and Vitamin D in You). STURDY was a seamless dose-finding and confirmatory, double-masked, response adaptive Bayesian randomized trial designed to find the best dose of vitamin D supplementation for fall prevention. Participants (n=688, ≥70 years with serum 25(OH)D of 10-29 ng/mL) were randomized to 200 (control), 1000 , 2000, or 4000 IU/day of vitamin D3.The first participant was randomized on 10/30/2015 and data collection ended on 5/31/2019. The primary outcome was time to first fall or death, and the secondary outcome was gait speed. Dr. Appel will present the main findings of the effect of vitamin D supplementation on time to first fall. Dr. Wanigatunga will present a more detailed analysis of the effect of vitamin D supplementation on fall characteristics, including indoor vs. outdoor falls, consequential falls, and repeat fall risk. Dr. Guralnik will present the effect of vitamin D supplementation on physical functioning, including gait speed, SPPB, 6-minute walk, and TUG performance. Dr. Schrack will present the effect of vitamin D supplementation on objectively measured physical activity.

Background: Necrotizing soft tissue infections (NSTIs) are typically characterized by extensive soft tissue destruction with systemic signs of toxicity, ranging from sepsis to septic shock. Our aim was to analyze the clinical characteristics, microbiological results, laboratory data, therapies, and outcome of patients with NSTIs admitted to an intensive care unit (ICU). Methods: A monocentric observational study of patients admitted to the ICU of a university hospital between January 2009 and December 2017. The demographic characteristics, comorbidities, clinical features, microbiology and laboratory results, organ dysfunctions, therapies, and outcome were retrospectively analyzed. Results: There were 59 patients and 70% males. The mean age (± SD) was 55 ± 18; type II (monomicrobial) NSTI was present in 36 patients (61%); the most common isolated pathogen was Streptococcus pyogenes in 28 patients (48%). Septic shock was diagnosed in 41 patients (70%). The most common organ dysfunctions were circulatory and renal in 42 (71%) and 38 patients (64%). The mean value (± SD) of serum lactate at admission to the ICU was 4.22 ± 5.42 mmol/l, the median SOFA score and SAPS II were 7 (IQR 4 - 10) and 46 (IQR 30.5 - 53). ICU mortality rate was 25%. Both SOFA score and serum lactate demonstrated a good prognostic value regarding ICU outcome (OR 1.29, 95%CI 1.07-1.57, P < 0.007 and OR 1.53, 95%CI 1.19-1.98, P < 0.001). A cut-off value for serum lactate of 6.55 mmol/L positively predicted mortality with 67% sensitivity and 97% specificity. Conclusion: NSTIs carry a high risk of septic shock and multiple organ dysfunction syndrome and thus are still associated with high mortality. In our study, the value of serum lactate at admission to the ICU correlated well with mortality. This easy-to-measure parameter could play a role in the decision-making process regarding prognosis and continuation of care.

The authors used the proposed method of mathematical and statistical processing of laboratory data (indicators of electrolyte metabolism and osteomarkers) of archived data of 82 patients with various bone diseases aged 9.90 ± 0.55 years compared the structural changes in the panel of ratios of individual electrolytes and the influence of individual indicators on them in personalized data, on the basis of which a conclusion was made about a single mechanism of coinciding influences in the exchange of bone tissue. At the same time, it was found that the complex of associated links detected by the vitamin influence on the panel of electrolyte ratios may differ signifcantly in some cases from each other. These differences consisted in highly pronounced differences in the activity of vitamin D in relation to various components of osteosynthesis and osteolysis, which are described in the modern literature. On this basis, the authors conclude that the used method (analytical system) allows to identify the functional connections of the dynamics of the indicator of vitamin D in individual cases with the dynamics of other indicators of bone, which signifcantly expands the informativeness of the results of laboratory examination of the patient in determining the leading systems the implementation of functional activity of the vitamin. The presented results justify the possibility of creating and describing different images of vitamin D-related changes in the plasma electrolyte composition, followed by their use in the identifcation of certain disorders of calcium metabolism and/or evaluating the effectiveness of the therapy used in each individual case.

Abstract Background Polycystic ovary syndrome (PCOS) is considered one of the most common endocrine disorders affecting females in their reproductive age. In PCOS, an imbalance between androgens, anti-Müllerian hormone (AMH) and follicle stimulating hormone (FSH), cause a halt of follicular growth. Insulin resistance (IR) is another important component of PCOS. There is increasing evidence that vitamin D affects insulin and glucose metabolism, Vitamin D plays a vital role in the regulation of glucose-insulin homeostasis. Objectives to assess the efficacy of vitamin D supplementation in improving ovulation induction in PCOS women (1ry outcome) and increasing pregnancy rate (secondary outcome). Patients and Methods 120 women diagnosed PCOS according to Rotterdam criteria and were resistant to CC treatment were randomly allocated into equal two groups: Group V: number of 60 patients received cholecalciferol + Metformin for 2 months. Group C: 60 patients received Metformin 2 months. After two months from the start:Both study groups started induction with Clomiphene Citrate added every month starting from the 3rd month to the 5th month (3 cycles of ovulation induction) in addition to previous drugs mentioned. Results In our study results, regulation of menstrual cycle occured in 63.6% of women who recieved vitamin D + metformin (group V) and ovulation was confirmed in 34.5% of the total number (55 women). Later, 18% of them got pregnant after 3 months of treatment. Added to that 16 women out of 39 (41%) got pregnant by the end of the follow up period with cumulative pregnancy rate (53%). On the other hand menstrual regularity in (group C: metformin) recorded 61% with ovulation percentage of 26.9% (n = 54). Followed by 14.8% pregnancy rate at the 3rd month., which increased to 27.5% by the end of the study out of 47.5% ovulated women (n = 40). Cumulative pregnancy rate 40%. Conclusion From the current study we can conclude that there is no significant difference of adding vitamin D to CC resistant PCOS regarding ovulation and pregnancy rates. However, it can augment metformin action and improves its outcome.

ObjectiveThe aim of this study was to evaluate the incidence and risk factors of gestational trophoblastic neoplasia (GTN) from hydatidiform moles (HMs) cytogenetically diagnosed in a prospective cohort setting.MethodsThe prospective observational cohort study included cases of cytogenetically defined molar pregnancies, which were diagnosed by a multiplex short tandem repeat polymorphism analysis. Cases were classified as androgenetic complete HMs (CHMs), diandric monogynic triploid partial HMs (PHMs), or biparental abortion. Gestational trophoblastic neoplasia was diagnosed according to the International Federation of Gynecology and Obstetrics 2000 criteria. Incidences for each category, that is, CHM, PHMs, and biparental abortion, were calculated. Clinical variables (age, partner age, gravidity, parity, height, weight, BMI, and gestational age) and laboratory data (serum human chorionic gonadotropin [hCG], white blood cell count, hemoglobin, and platelet count) were compared between spontaneous remission cases and GTN cases in androgenetic CHMs.ResultsAmong 401 cases, 380 were classified as follows: 232 androgenetic CHMs, 60 diandric monogynic PHMs, and 88 biparental abortions. A total of 35 cases (15.1%) of CHMs, but only 1 case of PHM (1.7%) and no biparental abortions, exhibited progression to GTN. The hCG value before evacuation was significantly higher in GTN cases than in spontaneous remission cases (P = 0.001, Kruskal-Wallis test). Patient age was also significantly higher in GTN cases than in spontaneous remission cases (P = 0.002, Student t test).ConclusionsUnder the cohort cytogenetic diagnosis setting, the traditional risk factors for GTN after molar pregnancy, hCG value before evacuation and age, were confirmed in androgenetic CHMs. The risk of GTN was lower for PHMs than for CHMs. However, 1 patient with cytogenetic PHMs developed into GTN.

Introduction: This study aims to assess the correlation of the age-adjusted Charlson comorbidity index (ACCI) with 5-year mortality in a surgically treated hip fracture population. Materials and Methods: A retrospective analysis was performed on 1057 patients aged 60 years and above who underwent surgery for hip fracture with a minimum of 5-year follow-up (92.2% 5-year follow-up rate) in a tertiary hospital. Manual review of patients’ electronic hospital records was performed to record demographic data, comorbidities, and length of stay. Mortality data were extracted from the hospital’s electronic medical records and corroborated with the National Electronic Health Record. Results: Of the 1057 patients, 283 (26.8%) were male. The majority of patients were 80 years of age and above (42.5%), with the oldest patient operated on age 102 with a mean age of 77.8 (8.6) years. Four hundred eighteen (39.5%) patients sustained extracapsular intertrochanteric fractures. The mean follow-up duration was 8 years and 3 days with an overall survivorship of 37.2%. A multiple regression model constructed with ACCI, age, gender, and fracture pattern demonstrated satisfactory predictive ability with a concordance statistic of 0.68. Patients with a higher ACCI category (≥6) had an increased 5-year mortality rate (41.8%) with an odds ratio of 13.6 (6.7-31.8, P < .001) compared to those with an ACCI category of 3 and below (89.3%). Discussion: The study demonstrates that ACCI correlated with 5-year mortality after surgical treatment of hip fracture. This information is pertinent in the counseling of patients with regard to their midterm survival following hip fracture surgery and may inform policy makers of the varied midterm survival rates in patients with differing ACCI scores and educate the allocation of health-care resources. Conclusion: The ACCI correlates with 5-year mortality after surgical treatment of hip fracture.
