Abstract
BACKGROUND Influenza circulation during the 2022-2023 season in the United States largely returned to pre-coronavirus disease 2019 (COVID-19)-pandemic patterns and levels. Influenza A(H3N2) viruses were detected most frequently this season, predominately clade 3C.2a1b.2a, a close antigenic match to the vaccine strain. METHODS To understand effectiveness of the 2022-2023 influenza vaccine against influenza-associated hospitalization, organ failure, and death, a multicenter sentinel surveillance network in the United States prospectively enrolled adults hospitalized with acute respiratory illness between 1 October 2022, and 28 February 2023. Using the test-negative design, vaccine effectiveness (VE) estimates against influenza-associated hospitalization, organ failures, and death were measured by comparing the odds of current-season influenza vaccination in influenza-positive case-patients and influenza-negative, SARS-CoV-2-negative control-patients. RESULTS A total of 3707 patients, including 714 influenza cases (33% vaccinated) and 2993 influenza- and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-negative controls (49% vaccinated) were analyzed. VE against influenza-associated hospitalization was 37% (95% confidence interval [CI]: 27%-46%) and varied by age (18-64 years: 47% [30%-60%]; ≥65 years: 28% [10%-43%]), and virus (A[H3N2]: 29% [6%-46%], A[H1N1]: 47% [23%-64%]). VE against more severe influenza-associated outcomes included: 41% (29%-50%) against influenza with hypoxemia treated with supplemental oxygen; 65% (56%-72%) against influenza with respiratory, cardiovascular, or renal failure treated with organ support; and 66% (40%-81%) against influenza with respiratory failure treated with invasive mechanical ventilation. CONCLUSIONS During an early 2022-2023 influenza season with a well-matched influenza vaccine, vaccination was associated with reduced risk of influenza-associated hospitalization and organ failure.

Abstract
Importance On June 21, 2023, the Centers for Disease Control and Prevention recommended the first respiratory syncytial virus (RSV) vaccines for adults aged 60 years and older using shared clinical decision-making. Understanding the severity of RSV disease in adults can help guide this clinical decision-making. Objective To describe disease severity among adults hospitalized with RSV and compare it with the severity of COVID-19 and influenza disease by vaccination status. Design, Setting, and Participants In this cohort study, adults aged 18 years and older admitted to the hospital with acute respiratory illness and laboratory-confirmed RSV, SARS-CoV-2, or influenza infection were prospectively enrolled from 25 hospitals in 20 US states from February 1, 2022, to May 31, 2023. Clinical data during each patient's hospitalization were collected using standardized forms. Data were analyzed from August to October 2023. Exposures RSV, SARS-CoV-2, or influenza infection. Main Outcomes and Measures Using multivariable logistic regression, severity of RSV disease was compared with COVID-19 and influenza severity, by COVID-19 and influenza vaccination status, for a range of clinical outcomes, including the composite of invasive mechanical ventilation (IMV) and in-hospital death. Results Of 7998 adults (median [IQR] age, 67 [54-78] years; 4047 [50.6%] female) included, 484 (6.1%) were hospitalized with RSV, 6422 (80.3%) were hospitalized with COVID-19, and 1092 (13.7%) were hospitalized with influenza. Among patients with RSV, 58 (12.0%) experienced IMV or death, compared with 201 of 1422 unvaccinated patients with COVID-19 (14.1%) and 458 of 5000 vaccinated patients with COVID-19 (9.2%), as well as 72 of 699 unvaccinated patients with influenza (10.3%) and 20 of 393 vaccinated patients with influenza (5.1%). In adjusted analyses, the odds of IMV or in-hospital death were not significantly different among patients hospitalized with RSV and unvaccinated patients hospitalized with COVID-19 (adjusted odds ratio [aOR], 0.82; 95% CI, 0.59-1.13; P = .22) or influenza (aOR, 1.20; 95% CI, 0.82-1.76; P = .35); however, the odds of IMV or death were significantly higher among patients hospitalized with RSV compared with vaccinated patients hospitalized with COVID-19 (aOR, 1.38; 95% CI, 1.02-1.86; P = .03) or influenza disease (aOR, 2.81; 95% CI, 1.62-4.86; P < .001). Conclusions and Relevance Among adults hospitalized in this US cohort during the 16 months before the first RSV vaccine recommendations, RSV disease was less common but similar in severity compared with COVID-19 or influenza disease among unvaccinated patients and more severe than COVID-19 or influenza disease among vaccinated patients for the most serious outcomes of IMV or death.

Abstract
In this work, silver‑bismuth oxide encapsulated 1,3,5-triazine-bis(4-methylbenzenesulfonyl)-hydrazone functionalized chitosan (SBO/FCS) nanocomposite was synthesized by a simple hydrothermal method. The amine (-NH2) group was functionalized by the addition of cyanuric acid chloride followed by 4-methylbenzenesulfonol hydrazide. The SBO/FCS has been characterized by FT-IR, X-ray diffraction, XPS, HR-SEM, HR-TEM, AFM, and thermogravimetry (TGA). Under the optimum conditions, the SBO/FCS sensor showed brilliant electrochemical accomplishment for the sensing of glucose and H2O2 by a limit of detection (LOD) of 0.057 μM and 0.006 μM. It also showed linearity for glucose 0.008-4.848 mM and for H2O2 of 0.01-6.848 mM. Similarly, the sensor exhibited a low sensitivity to glucose (32 μA mM-1 cm-2) and a good sensitivity to H2O2 (295 μA mM-1 cm-2). In addition, that the prepared electrode could be used to sense the glucose and H2O2 levels in real samples such as blood serum and HeLa cell lines. The screen printed electrode (SPE) immunosensor could sense the E. coli O157:H7 concurrently and quantitatively with a linear range of 1.0 × 101-1.0 × 109 CFU mL-1 and a LOD of 4 CFU mL-1. Likewise, the immunosensor efficiently detect spiked E. coli O157:H7 in milk, chicken, and pork samples, with recoveries ranging from 89.70 to 104.72 %, demonstrating that the immunosensor was accurate and reliable.

Abstract
Cancer has emerged as a potentially lethal illness, which recently upsurged in the mortality rate. Animal-derived compounds could be promising targets with higher efficacy and low toxicity in anticancer therapy. The present study aimed to explore the presence of anticancer potential compounds in Hirudinaria manillensis methanolic extract and their anticancer potential against various cancer cell types and target identification by Auto dock method. Initially, the identification of bioactive compounds was achieved by GC-MS analysis followed by the anticancer activity by MTT assay against A549, HeLa, MDA-MB-231, MG-63, and MOLT-4. Further, the effect of a lead compound on the cancer cell target was analyzed by the Auto dock method. GC-MS analysis results revealed the presence of 25 different bioactive compounds including anticancer potential compounds, such as Lupeol, Carvacrol, and Demecolcine. Interestingly, MTT assay results demonstrated the anticancer potential of Hirudinaria manillensis extract (LE) against various cancer cell lines, such as A549 (54.60 µg/ml), HeLa (19.93 µg/ml), MDA-MB-231 (20.23 µg/ml), MG-63 (20.04 µg/ml), and MOLT-4 (171.8 µg/ml), respectively. Among these cell types, the maximum inhibition was observed against HeLa with the IC50 concentration of 19.93 µg/ml. Furthermore, Demecolcine compound was docked with the EGFR tyrosine kinase showed the binding affinity of the docked complex was predicted to be - 6.2 kcal/mol. Thus, we conclude that H. manillensis has a significant anticancer effect on human cancer cell lines and could be used as a natural target which paves the way for further studies on biomedical applications in cancer therapeutics.

Abstract
Primary care is often the weakest link in health systems despite its acknowledged central importance in promoting population's health at economical cost. A key reason for the lacunae is that both scholars and practitioners working on the subject typically underestimate the enormity of the task and the range of complementary measures required to build an effective primary care system. The objective of the paper is to highlight theoretical gaps and practical limitations to strengthening primary care. The challenges and difficulties are illustrated through a case study of China where primary care continues to struggle despite the government's strong political, financial and policy support in recent years. In this paper, we review the development of primary health care in China and how it is governed, provided, and financed, highlighting the gaps and misalignments that undermine its performance. We argue that governance deficiencies coupled with flawed financing and payments arrangements are major impediments to improving performance. China's experience offers valuable lessons for other governments seeking to strengthen primary health care.

Abstract
Lignocellulosic fiber-reinforced polymer composites are the most extensively used modern-day materials with low density and better specific strength specifically developed to render better physical, mechanical, and thermal properties. Synthetic fiber-reinforced composites face some serious issues like low biodegradability, non-environmentally friendly, and low disposability. Lignocellulosic or natural fiber-reinforced composites, which are developed from various plant-based fibers and animal-based fibers are considered potential substitutes for synthetic fiber composites because they are characterized by lightweight, better biodegradability, and are available at low cost. It is very much essential to study end-of-life (EoL) conditions like biodegradability for the biocomposites which occur commonly after their service life. During biodegradation, the physicochemical arrangement of the natural fibers, the environmental conditions, and the microbial populations, to which the natural fiber composites are exposed, play the most influential factors. The current review focuses on a comprehensive discussion of the standards and assessment methods of biodegradation in aerobic and anaerobic conditions on a laboratory scale. This review is expected to serve the materialists and technologists who work on the EoL behaviour of various materials, particularly in natural fiber-reinforced polymer composites to apply these standards and test methods to various classes of biocomposites for developing sustainable materials.

Abstract
On June 21, 2023, CDC's Advisory Committee on Immunization Practices recommended respiratory syncytial virus (RSV) vaccination for adults aged ≥60 years, offered to individual adults using shared clinical decision-making. Informed use of these vaccines requires an understanding of RSV disease severity. To characterize RSV-associated severity, 5,784 adults aged ≥60 years hospitalized with acute respiratory illness and laboratory-confirmed RSV, SARS-CoV-2, or influenza infection were prospectively enrolled from 25 hospitals in 20 U.S. states during February 1, 2022-May 31, 2023. Multivariable logistic regression was used to compare RSV disease severity with COVID-19 and influenza severity on the basis of the following outcomes: 1) standard flow (<30 L/minute) oxygen therapy, 2) high-flow nasal cannula (HFNC) or noninvasive ventilation (NIV), 3) intensive care unit (ICU) admission, and 4) invasive mechanical ventilation (IMV) or death. Overall, 304 (5.3%) enrolled adults were hospitalized with RSV, 4,734 (81.8%) with COVID-19 and 746 (12.9%) with influenza. Patients hospitalized with RSV were more likely to receive standard flow oxygen, HFNC or NIV, and ICU admission than were those hospitalized with COVID-19 or influenza. Patients hospitalized with RSV were more likely to receive IMV or die compared with patients hospitalized with influenza (adjusted odds ratio = 2.08; 95% CI = 1.33-3.26). Among hospitalized older adults, RSV was less common, but was associated with more severe disease than COVID-19 or influenza. High disease severity in older adults hospitalized with RSV is important to consider in shared clinical decision-making regarding RSV vaccination.

Abstract
Lectins are non-immune glycoproteins or proteins having a unique capacity to interact with carbohydrate ligands found on the surface of their host cells. In the present investigation, the lectin was purified from the hemolymph of freshwater crab, Oziotelphusa naga and its antimicrobial, anti-inflammatory and anti-arthritic activity was analysed. The preliminary characterization of the hemagglutinin was carried out to identify the erythrocyte and sugar specificity, optimum pH and temperature and cation dependency. The agglutinin was found to be highly specific to rabbit erythrocyte and inhibited by fetuin and α-lactose. Maximum hemagglutination activity was noted at pH 7.5-8 and temperature 20-40 °C. An O-acetyl sialic acid specific 75 kDa hemolymph lectin, designated as NagLec was isolated from the freshwater crab, Oziotelphusa naga by affinity chromatography on fetuin coupled Sepharose 4 B, with a purification fold of 185. The bacteria Staphylococcus aureus, Proteus mirabilis and fungus Candida albicans had the greatest zone of inhibition when treated with NagLec. The results of the Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) assays showed that the purified lectin inhibited the growth of Staphylococcus aureus at 0.031 and 0.065 μg/ml, which proved the bactericidal property of NagLec. NagLec generated alterations on the bacterial cells and led to protein leakage, which was dosage (24 and 48 μg/ml) and time dependent (10-40 min). COX and LOX enzyme was inhibited to 49.43% and 61.81% with 100 μg/ml concentration of NagLec respectively, demonstrating NagLec's ability to reduce inflammation. Furthermore, NagLec (500 μg) suppressed protein denaturation up to 77.12% whereas diclofenac sodium (a standard drug) was inhibited by 89.36%. The results indicate that NagLec, a sialic acid specific lectin isolated from the freshwater crab O. naga could be formulated as a nano drug in future owing to its antimicrobial, anti-inflammatory and anti-arthritic potential that could be targeted to specific pathogenic microbes and treat arthritis.

Abstract
The respiratory infection tuberculosis is caused by the bacteria Mycobacterium tuberculosis and its unrelenting spread caused millions of deaths around the world. Hence, it is needed to explore potential and less toxic anti-tubercular drugs. In the present work, we report the synthesis and antitubercular activity of four different (hydrazones 7-12, O-ethynyl oximes 19-24, triazoles 25-30, and isoxazoles 31-36) hybrids. Among these hybrids 9, 10, 33, and 34, displayed high antitubercular activity at 3.12 g/mL with >90% of inhibitions. The hybrids also showed good docking energies between -6.8 and -7.8 kcal/mol. Further, most active molecules were assayed for their DNA gyrase reduction ability towards M. tuberculosis and E.coli DNA gyrase by the DNA supercoiling and ATPase gyrase assay methods. All four hybrids showed good IC50 values comparable to that of the reference drug. In addition, the targets were also predicted as a potential binder for papain-like protease (SARS CoV-2 PLpro) by molecular docking and a good interaction result was observed. Besides, all targets were predicted for their absorption, distribution, metabolism, and excretion - toxicity (ADMET) profile and found a significant amount of ADMET and bioavailability.

Abstract
In this study, silver-functionalized bismuth oxide (AgBi2O3) nanoparticles (SBO NPs) were successfully synthesized by a highly efficient hydrothermal method. The as-synthesized SBO nanoparticles were characterized using FT-IR, P-XRD, XPS, HR-SEM, and HR-TEM analytical methods. It was found that the NPs were in spherical shape and hexagonal crystal phase. The newly prepared SBO electrode was further utilized for the detection of glucose, NO2- and H2O2 by cyclic voltammetry (CV) and amperometric methods. The electrodes exhibited high sensitivity (2.153 μA mM-1 cm-2 for glucose, 22 μA mM-1 cm-2 for NO2- and 1.72 μA mM-1 cm-2 for H2O2), low LOD (0.87 μM for glucose, 2.8 μM for NO2- and 1.15 μM for H2O2) and quick response time (3 s for glucose, 2 s for both NO2- and H2O2 respectively). The sensor exhibited outstanding selectivity despite the presence of various interferences. The developed sensor exhibited good repeatability, reproducibility, and stability. In addition, the sensor was used to measure glucose, H2O2 in human serum, and NO2- in milk and river water samples, demonstrating its potential for use in the real sample.

Abstract
As of April 2023, the COVID-19 pandemic has resulted in 1.1 million deaths in the United States, with approximately 75% of deaths occurring among adults aged ≥65 years (1). Data on the durability of protection provided by monovalent mRNA COVID-19 vaccination against critical outcomes of COVID-19 are limited beyond the Omicron BA.1 lineage period (December 26, 2021-March 26, 2022). In this case-control analysis, the effectiveness of 2-4 monovalent mRNA COVID-19 vaccine doses was evaluated against COVID-19-associated invasive mechanical ventilation (IMV) and in-hospital death among immunocompetent adults aged ≥18 years during February 1, 2022-January 31, 2023. Vaccine effectiveness (VE) against IMV and in-hospital death was 62% among adults aged ≥18 years and 69% among those aged ≥65 years. When stratified by time since last dose, VE was 76% at 7-179 days, 54% at 180-364 days, and 56% at ≥365 days. Monovalent mRNA COVID-19 vaccination provided substantial, durable protection against IMV and in-hospital death among adults during the Omicron variant period. All adults should remain up to date with recommended COVID-19 vaccination to prevent critical COVID-19-associated outcomes.

Abstract
Leishmaniasis is a protozoal disease declared as an endemic in areas suffering from severe malnutrition and poverty. The factors associated with poverty like low income, ecological factors, and malnutrition cause disruption in immunity and host defense increasing risk of infection. Altered resistance to infection and host susceptibility are associated with low micronutrient levels in undernourished patients. Malnutrition has been recognized as a poor predictive marker for leishmaniasis, in particular the deficiency of trace elements like zinc, iron, and vitamin A, B, C, D which has a prominent function in the regulation of innate and adaptive immunity, cell proliferation, human physiology, etc. Malnourishment can exacerbate host sensitivity and pathophysiologic intensity to infection in variety of ways, whereas infection can enhance underlying poor nutrition or enhance host vulnerability and sandfly's urge to attack specific hosts. The intensity of leishmaniasis can be influenced by body mass and micronutrient availability in the blood. Vitamin D, C, zinc, and iron are proved effective in inhibiting the growth of leishmaniasis in both amastigote or promastigote forms, either directly or by acting as precursor for a pathway which inhibits the parasite growth. This article elucidates a new perception to the crucial role of micronutrients and their probable role in the therapeutic outcomes of leishmaniasis. Since there is requirement of novel drugs to fight drug resistance and relapse of leishmaniasis, this article may pave way to understand the importance of micronutrients and their role in therapeutic outcomes of leishmaniasis.

Abstract
IMPORTANCE A safe and effective treatment for recurrent Clostridioides difficile infection (CDI) is urgently needed. Antibiotics kill toxin-producing bacteria but do not repair the disrupted microbiome, which promotes spore germination and infection recurrence. OBJECTIVES To evaluate the safety and rate of CDI recurrence after administration of investigational microbiome therapeutic SER-109 through 24 weeks. DESIGN, SETTING, AND PARTICIPANTS This phase 3, single-arm, open-label trial (ECOSPOR IV) was conducted at 72 US and Canadian outpatient sites from October 2017 to April 2022. Adults aged 18 years or older with recurrent CDI were enrolled in 2 cohorts: (1) rollover patients from the ECOSPOR III trial who had CDI recurrence diagnosed by toxin enzyme immunoassay (EIA) and (2) patients with at least 1 CDI recurrence (diagnosed by polymerase chain reaction [PCR] or toxin EIA), inclusive of their acute infection at study entry. INTERVENTIONS SER-109 given orally as 4 capsules daily for 3 days following symptom resolution after antibiotic treatment for CDI. MAIN OUTCOMES AND MEASURES The main outcomes were safety, measured as the rate of treatment-emergent adverse events (TEAEs) in all patients receiving any amount of SER-109, and cumulative rates of recurrent CDI (toxin-positive diarrhea requiring treatment) through week 24 in the intent-to-treat population. RESULTS Of 351 patients screened, 263 were enrolled (180 [68.4%] female; mean [SD] age, 64.0 [15.7] years); 29 were in cohort 1 and 234 in cohort 2. Seventy-seven patients (29.3%) were enrolled with their first CDI recurrence. Overall, 141 patients (53.6%) had TEAEs, which were mostly mild to moderate and gastrointestinal. There were 8 deaths (3.0%) and 33 patients (12.5%) with serious TEAEs; none were considered treatment related by the investigators. Overall, 23 patients (8.7%; 95% CI, 5.6%-12.8%) had recurrent CDI at week 8 (4 of 29 [13.8%; 95% CI, 3.9%-31.7%] in cohort 1 and 19 of 234 [8.1%; 95% CI, 5.0%-12.4%] in cohort 2), and recurrent CDI rates remained low through 24 weeks (36 patients [13.7%; 95% CI, 9.8%-18.4%]). At week 8, recurrent CDI rates in patients with a first recurrence were similarly low (5 of 77 [6.5%; 95% CI, 2.1%-14.5%]) as in patients with 2 or more recurrences (18 of 186 [9.7%; 95% CI, 5.8%-14.9%]). Analyses by select baseline characteristics showed consistently low recurrent CDI rates in patients younger than 65 years vs 65 years or older (5 of 126 [4.0%; 95% CI, 1.3%-9.0%] vs 18 of 137 [13.1%; 95% CI, 8.0%-20.0%]) and patients enrolled based on positive PCR results (3 of 69 [4.3%; 95% CI, 0.9%-12.2%]) vs those with positive toxin EIA results (20 of 192 [10.4%; 95% CI, 6.5%-15.6%]). CONCLUSIONS AND RELEVANCE In this trial, oral SER-109 was well tolerated in a patient population with recurrent CDI and prevalent comorbidities. The rate of recurrent CDI was low regardless of the number of prior recurrences, demographics, or diagnostic approach, supporting the beneficial impact of SER-109 for patients with CDI.

Abstract
In this work, pure ZnZrO2 and chitosan supported (ZnZrO2/CS) nanocomposite have been synthesized at low coast by hydrothermal method. FT-IR, Micro Raman, PXRD, HR-SEM-EDAX, HR-TEM, AFM, BET and XPS were used to analyze the structural and morphological properties of the fabricated nanocomposites. The fabricated ZnZrO2 and ZnZrO2/CS nanocomposites were measured for their electrocatalytic activity towards glucose and hydrogen peroxide determinations. The ZnZrO2/CS sensor exhibited wide detection range (5 μM to 5.85 mM), high sensitivity (6.78 μA mM-1 cm-2), LOD (2.31 μM), and long-term stability for glucose detection in alkaline solution. Also, as a multifunctional electrochemical sensor, ZnZrO2/CS sensor exhibits excellent sensing ability towards hydrogen peroxide, with a wide dynamic range (20 μM to 6.85 mM), a high sensitivity (2.22 μA mM-1 cm-2), and a LOD (2.08 μM) (S/N = 3). The electrochemical measurement shows that the ZnZrO2/CS sensor has excellent catalytic activity and a much LOD than ZnZrO2. The modified electrode showed excellent anti interference nature. Furthermore, this ZnZrO2/CS electrode was used to detection of glucose and H2O2 in human blood serum and HeLa cells respectively.

Abstract
Background Universal PCR and Next Generation Sequencing (uPCR/NGS) is a major advancement in microbiology. It is a highly sensitive and specific test that amplifies ribosomal RNA in samples to detect bacterial and fungal pathogens. We investigated the uPCR/NGS tests sent from Henry Ford Health (HFH) and the effect obtaining this test had on patient care. Methods We completed a retrospective, observational study assessing all consecutive uPCR/NGS tests obtained from at HFH from 2016-2021. This included uPCR/NGS for detection of bacterial, fungal, mycobacterium tuberculosis (MTB), and non-tuberculosis mycobacterium (NTM). All samples were of non-blood fluids and tissue samples. Patients concurrent tissue cultures and blood cultures from day of uPCR/NGS, and within 6 months of obtaining the uPCR/NGS sample were evaluated. Primary outcomes included if uPCR/NGS testing resulted in a change of choice or duration of antibiotic therapy. Results At HFH, 226 uPCR/NGS tests from 111 samples were analyzed. This included 83 bacterial, 51 MTB, 51 NTM, and 41 fungal uPCR/NGS tests. Of the 226 uPCR/NGS tests, 31 tests (13.7%) resulted with positive result on uPCR/NGS. A total of 31 tests (13.7%) were ordered on a known culture positive sample, and 195 (86.3%) were ordered on a culture negative sample. Of samples sent from a culture positive sample, 7 (22.6%) resulted with positive uPCR/NGS results. 3 (42.9%) matched the tissue cultures, and 2 (28.6%) matched the patients’ blood cultures. None of the patients had any change in choice or duration of antibiotics based on uPCR/NGS results. Of the samples sent from a culture negative sample, 24 (12.3%) samples resulted with positive uPCR/NGS results. 2 (8.3%) matched a patient’s tissue cultures and none matched blood cultures. Change in antibiotic choice or duration occurred in 16 (17.6%) patients. The samples with the highest rates of change in management included cerebrospinal fluid (42.9%), brain tissue (36.4%), cardiac valvular tissue (27.3%), lymph nodes (25%), synovial fluid (20%).
Flowchart of Results and Impact on Management ![]() Conclusion Our results show that uPCR/NGS has an overall low percent of impact in clinical outcomes, but it is a useful test in when used on a culture negative sample in certain sample types, along with a high index of suspicion for infection.

Abstract
Background Prior studies evaluating the sensitivity blood cultures utilizing the Virtuo blood culture system versus the VersaTREK blood culture system have suggested increased sensitivity with the Virtuo system. Studies evaluating if this increased sensitivity effects patient outcomes are lacking. This study evaluates the effect of replacing the VersaTREK system with the Virtuo system on morbidity and mortality in patients with Staphylococcus aureus bacteremia. Methods This quasi-experimental study was performed at Henry Ford Health System in Southeast Michigan. We analyzed all patients with positive blood cultures for Staphylococcus aureus between 3/1/18 and 9/30/18 (VersaTREK system) and 3/1/19 and 9/30/19 (Virtuo system). The VersaTREK arm had 267 patients and the Virtuo arm 404. Patients transferred to or from outside facilities with ongoing bacteremia were excluded. Primary outcomes were differences in length of stay, mortality at 14, 30, and 90 days from completion of therapy, and hospitalization for recurrence of bacteremia within 30 days. Secondary outcomes were differences in length of therapy, rates of diagnostic imaging tests to assess for persistent foci of infection or an unknown source of persistent bacteremia, and length of bacteremia. Data were analyzed using SPSS for Macintosh using Pearson’s chi-square test and Student’s t-test. A p < 0.05 was considered statistically significant. Results Demographics of the study populations were equal however, the Charlson Comorbidity Index for VersaTREK arm compared to Virtuo (3.5 to 3.1) trended toward significance (p=0.05) (Table 1). There was no difference in length of bacteremia, lengths of antibiotic therapy, CT scans, or echocardiograms performed. More MRIs were performed in the Virtuo arm (p=< 0.001) (Table 2). There was no difference in recurrence of bacteremia, patient death due to bacteremia, length of hospital stay, or 30 day readmission for recurrence of bacteremia (Table 3).
![]() ![]() ![]() Conclusion This is the first study to evaluate how increased sensitivity of a blood culture system effects patient outcomes. Our results suggest that Staphylococcus aureus bacteremia may be over treated in blood cultures systems that are highly sensitive. Further prospective studies are needed to explore this further.

Abstract
Abstract
Background
Vancomycin (VAN) therapy for C. difficile infection (CDI) is effective with > 80% clinical response (CR) but is associated with 20–30% recurrence rate (rCDI). Secondary bile acids (2° BAs) inhibit C. difficile germination and help prevent rCDI. VAN depletes the gut microbiome decreasing the conversion of primary bile acids to 2° BAs. Ridinilazole (RDZ) is a highly selective anti-CDI, DNA-binding antibiotic in development for the treatment of CDI and prevention of rCDI.
Methods
A global, double-blinded, randomized Phase 3 trial assessed a 10-day treatment with RDZ 200 mg BID vs VAN 125 mg QID for CDI. The primary endpoint was sustained clinical response (SCR) defined as CR and no rCDI through 30 days post-end of treatment (EOT). Other endpoints included rCDI, microbiome diversity and composition, and microbiome-derived 2° BAs concentration. rCDI was defined as a new episode of diarrhea with confirmed positive free toxin test (FTT), requiring additional CDI therapy. All participants were monitored for treatment emergent adverse events (TEAE).
Results
Of the 759 patients (pts) enrolled, 745 were included in the mITT population (RDZ n=370, VAN n=375). RDZ achieved a numerically higher SCR rate than VAN (73.0% vs 70.7%) p=0.4672. RDZ resulted in a significant reduction in rCDI rate (8.1% vs 17.3%, p=0.0002) (Fig 1). In a pre-specified subpopulation, this was most notable in pts not receiving other antibiotics (rCDI 6.7% in RDZ vs 16.5% in VAN, p=0.0005). Microbiome alpha diversity was higher for RDZ vs VAN at EOT and EOT+30d (p< 0.0001 and p≤ 0.0007 respectively, Fig 2) as were relative abundance (p< 0.0001 and p=0.0203 respectively), and concentrations of 2° BAs (Fig 3). Higher microbiome diversity and concentrations of 2° BAs at EOT were associated with both lower rCDI and higher SCR rates. RDZ was well tolerated (pts with ≥ 1 TEAE: RDZ 36.4% vs VAN 35.5%, treatment discontinuation due to TEAE: RDZ 0.8% vs. VAN 2.9%).
Conclusion
RDZ was effective for sustained clinical response and safe for the treatment of patients with CDI. This was most notable in pts not receiving antibiotics. Compared to VAN, RDZ patients had faster recovery of fecal 2° BA, consistent with the preservation of microbiome diversity, resulting in a significantly lower rate of rCDI.

Abstract
Background Eravacycline (ERV) is a fluorocycline with in vitro activity against Clostridioides difficile infection (CDI). The purpose of this study was to evaluate the usage of ERV in the management of CDI. Methods IRB-approved, retrospective case series in a health system that added ERV to formulary in 9/2019. All patients between 9/2019 and 2/2020 treated with adjunctive ERV for > 24 hours for severe, recurrent, or fulminant CDI were included. Exclusion criteria: pregnant, age < 18 years. Primary outcome: all-cause mortality at 30 days (d) from start of ERV. Secondary outcomes: clinical cure, colectomy, and recurrence within 30 d. Data was reported using descriptive statistics and measures of central tendency. Results 14 patients included: severe (4, 29%), recurrent (4, 29%), and fulminant CDI (6, 43%) (table 1). Infectious diseases consult: 14/14, median time to consult 1 (1, 2) d. Surgery consult: 1 severe and 5 fulminant CDI cases, median time to consult 1 (1, 3) d. Prior to ERV initiation, 10 patients were on oral vancomycin (PO VAN) and intravenous metronidazole (IV MTZ), one was on PO VAN, two were on IV MTZ, and one was on no CDI therapy. After ERV was initiated, six patients were on ERV, PO VAN, and IV MTZ combination and eight patients were on ERV and PO VAN concurrently. The reason for using ERV was fulminant CDI (6, 42.8%), severe CDI (4, 29%), unable to tolerate other CDI medications (3, 21%), refractory CDI (3, 21%), and recurrent CDI (1, 7%). Time to eravacycline initiation 1.5 d (1, 3.75) with median duration of 6 d (4.5, 7.75). 30-day all-cause mortality 2 (14%), all were in-hospital; 1 (7%) hospice. Clinical cure occurred in 12 (86%). Two (14%) required colectomy; one received surgery on the same day of CDI diagnosis and ERV initiation and the other had surgery 4 days before ERV initiation. Two patients with recurrent CDI received fecal microbiota transplant outpatient, one of which also received bezlotoxumab. Zero recurrences and one readmission within 30 d.
Patient demographics, severity, and clinical outcomes ![]() Conclusion ERV appears to be a potential adjunctive therapy for severe, recurrent, or fulminant CDI. Prospective studies are needed to further investigate the safety and efficacy of ERV in serious CDI. Disclosures All Authors: No reported disclosures.

Abstract
BACKGROUND The utility of surveillance bronchoscopy (SB) for the clinical management of lung transplant recipients (LTRs) is undefined. This study evaluates the role of SB in the monitoring and care of LTRs. METHODS We retrospectively analyzed all LTRs who had SB at Henry Ford Hospital in Detroit, Michigan between August 2014 and August 2019. Bronchoscopies performed for clinical symptoms, new radiographic abnormalities, and to assess stents or acute rejection were excluded. A total of 107 LTRs and 449 bronchoscopies were analyzed. The primary outcome was the rate of change in clinical care based on microbiologic and pathologic test results. Secondary outcomes were rates of microbiologic and pathologic test positivity and rates of adverse effects. RESULTS The most common microbiologic tests performed on bronchoalveolar lavage were bacterial (96.9%), fungal (95.3%), and acid-fast bacillus (95.1%) stains and cultures. Of 2560 microbiologic tests, 22.0% were positive and resulted in therapy changes for 2.9%. Positive galactomannan, acid-fast bacillus tests, and Pneumocystis jirovecii antigen/polymerase chain reaction did not result in therapy changes. Of the 370 transbronchial biopsies performed, 82.2% were negative for acute rejection and 13% were positive for A1/A2 rejection. Immunosuppressive therapy changes occurred after 15.8% with reduction in immunosuppression due to positive microbiologic tests in 16.9%. Adverse events occurred in 8.0% of patients. CONCLUSION Diagnostic stewardship is warranted when performing SB in LTRs.

Abstract
BACKGROUND:
Nano-materials derived from sustainable and biodegradable polymers, are the most attractive materials among the researchers. Polymeric nano-biocomposites (PNBCs) are a specific class of materials derived by combining nanosized fillers with polymer materials and the most commonly used nano-fillers were hydroxyapatite, organic or inorganic metal nanoparticles, clays and so on.
METHODS:
Many of the recent researches rendered its focus towards the utilization of biopolymer based hydrogel materials for the fabrication of analyte sensors and electrode modifiers owing to their high permeability nature and faster, mobilization of electrons. Such biopolymer hydrogelutilize newer printing methods in electrode prototyping, which renders portable, flexible, and advanced bioelectronics sensor with high performance characteristics. Few researchers have also stated the use of polyaniline reinforced biocomposites for the fabrication of electro-chemical sensors and actuators because of their advantageous properties, which makes them a potential material choice for electronics applications.
RESULTS:
Nano-particles of polyaniline were proved to improve the detection limit and sensitivity of the sensor even when used for recognizing a single molecules. Bionanocomposites possess excellent thermo-mechanical properties in the designed nanocomposite, even at low nanoparticle concentrations. In fact, these materials have high hardness and stability, giving rise to excellent mechanical characteristics. Furthermore, the incorporation of nanoparticles into a biopolymeric matrix enhanced its electrical conductivity, barrier properties, and consistency. Also, the powerful interaction between biopolymers and functional groups of nanoparticles increased the strength of bio-nanocomposites.
CONCLUSION:
Nanobiocomposites based biosensors were found to possess high specificity, sensitivity, and wider target spectrum. Current review deals with the use of sustainable and renewable biocomposites for the preparation of biosensors and actuators, their properties like sensitivity, limit of detection, advantages over the synthetic material and environmental hazards.

Abstract
Background Characterization of disease progression and outcomes after coronavirus disease 2019 (COVID-19)–related hospitalization in vaccinated compared with unvaccinated individuals is limited. Methods This was a retrospective case–control study of symptomatic vaccinated (cases) and unvaccinated (controls) participants hospitalized for COVID-19 between December 30, 2020, and September 30, 2021, in Southeast Michigan. Hospitalized adult patients with lab-confirmed COVID-19 were identified through daily census report. Breakthrough infection was defined as detection of severe acute respiratory syndrome coronavirus 2 ≥14 days after completion of the primary vaccination series. The association between prior vaccination and critical COVID-19 illness (composite of intensive care unit [ICU] admission, invasive mechanical ventilation [IMV], 28-day mortality) was examined. Results Two hundred ten (39%) fully vaccinated and 325 (61%) unvaccinated patients were evaluated. Compared with controls, cases were older, had more comorbidities (4 [3–7] vs 2 [1–4]; P < .001), and were more likely to be immunocompromised. Cases had less severe symptoms compared with controls (2 [1–2] vs 2 [2–3]; P < .001) and were less likely to progress to critical COVID-19 illness (33.3% vs 45.5%; P < .001); 28-day mortality was significantly lower in cases (11.0% vs 24.9%; P < .001). Symptom severity (odds ratio [OR], 2.59; 95% CI, 1.61–4.16; P < .001) and modified Sequential Organ Failure Assessment score on presentation (OR, 1.74; 95% CI, 1.48–2.06; P < .001) were independently associated with development of critical COVID-19 illness. Prior vaccination (OR, 0.528; 95% CI, 0.307–0.910; P = .020) was protective. Conclusions COVID-19-vaccinated patients were less likely to develop critical COVID-19 illness and more likely to survive. Disease severity at presentation was a predictor of adverse outcomes regardless of vaccination status.

Abstract
Background Characterizations of coronavirus disease 2019 (COVID-19) vaccine breakthrough infections are limited. We aim to characterize breakthrough infections and identify risk factors associated with outcomes. Methods This was a retrospective case series of consecutive fully vaccinated patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a multicenter academic center in Southeast Michigan, between December 30, 2020, and September 15, 2021. Results A total of 982 patients were identified; the mean age was 57.9 years, 565 (59%) were female, 774 (79%) were White, and 255 (26%) were health care workers (HCWs). The median number of comorbidities was 2; 225 (23%) were immunocompromised. BNT162b2 was administered to 737 (75%) individuals. The mean time to SARS-CoV-2 detection was 135 days. The majority were asymptomatic or exhibited mild to moderate disease, 154 (16%) required hospitalization, 127 (13%) had severe–critical illness, and 19 (2%) died. Age (odds ratio [OR], 1.14; 95% CI, 1.04–1.07; P < .001), cardiovascular disease (OR, 3.02; 95% CI, 1.55–5.89; P = .001), and immunocompromised status (OR, 2.57; 95% CI, 1.70–3.90; P < .001) were independent risk factors for hospitalization. Additionally, age (OR, 1.06; 95% CI, 1.02–1.11; P = .006) was significantly associated with mortality. HCWs (OR, 0.15; 95% CI, 0.05–0.50; P = .002) were less likely to be hospitalized, and prior receipt of BNT162b2 was associated with lower odds of hospitalization (OR, 0.436; 95% CI, 0.303–0.626; P < .001) and/or death (OR, 0.360; 95% CI, 0.145–0.898; P = .029). Conclusions COVID-19 vaccines remain effective at attenuating disease severity. However, patients with breakthrough infections necessitating hospitalization may benefit from early treatment modalities and COVID-19-mitigating strategies, especially in areas with substantial or high transmission rates.

Abstract
OBJECTIVES Approximately 25% of patients with Clostridioides difficile infection (CDI) will experience recurrence, which is greater in immunocompromised patients. We report experience with an institutional guideline targeting high-risk immunocompromised patients. METHODS This was a retrospective cohort of consecutive patients with CDI who met institutional criteria for bezlotoxumab due to high risk for recurrent CDI between June 1, 2017, and November 30, 2018. The primary endpoint of recurrent CDI within 12 weeks was compared between patients who received the standard of care (SoC) plus or minus bezlotoxumab. RESULTS Twenty-three patients received bezlotoxumab infusion plus SoC and were compared to 30 SoC patients. 84% of patients were immunocompromised and 54.7% were transplant recipients. The primary endpoint occurred in 13% of bezlotoxumab patients compared to 23.3% of SoC patients. No serious adverse effects were identified. CONCLUSION Bezlotoxumab was associated with a meaningful reduction in recurrent CDI in this cohort largely comprising immunocompromised and transplant patients. Larger studies are warranted to evaluate bezlotoxumab in this population.

Abstract
Background Corticosteroids use in severe coronavirus disease 2019 (COVID-19) improves survival; however, the optimal dose is not established. We aim to evaluate clinical outcomes in patients with severe COVID-19 receiving high-dose corticosteroids (HDC) versus low-dose corticosteroids (LDC). Methods This was a quasi-experimental study conducted at a large, quaternary care center in Michigan. A corticosteroid dose change was implemented in the standardized institutional treatment protocol on November 17, 2020. All patients admitted with severe COVID-19 that received corticosteroids were included. Consecutive patients in the HDC group (September 1 to November 15, 2020) were compared to the LDC group (November 30, 2020 to January 20, 2021). High-dose corticosteroids was defined as 80 mg of methylprednisolone daily in 2 divided doses, and LDC was defined as 32–40 mg of methylprednisolone daily in 2 divided doses. The primary outcome was all-cause 28-day mortality. Secondary outcomes included progression to mechanical ventilation, hospital length of stay (LOS), discharge on supplemental oxygen, and corticosteroid-associated adverse events. Results Four-hundred seventy patients were included: 218 (46%) and 252 (54%) in the HDC and LDC groups, respectively. No difference was observed in 28-day mortality (14.5% vs 13.5%, P = .712). This finding remained intact when controlling for additional variables (odds ratio, 0.947; confidence interval, 0.515–1.742; P = .861). Median hospital LOS was 6 and 5 days in the HDC and LDC groups, respectively (P < .001). No differences were noted in any of the other secondary outcomes. Conclusions Low-dose methylprednisolone had comparable outcomes including mortality to high-dose methylprednisolone for the treatment of severe COVID-19.

Abstract
BACKGROUND Geriatric psychiatry has yet to receive its due recognition in India. There is increasing evidence of a rise in morbidity, mortality, hospitalization, and loss of functional status related to common mental disorders in the elderly patients. Collaborative care approach, including a clinical pharmacist, is one of the possible approaches to cope with geriatric patients with psychiatric patients. OBJECTIVE The study aimed to assess the impact of pharmacotherapy management of geriatric patients in collaboration with pharmacist and psychiatrist. MATERIALS AND METHODS A prospective interventional study was conducted in the psychiatry outpatient department of a tertiary care hospital in Mysore over 6 months. Geriatric patients who were newly diagnosed with depression, bipolar affective disorder (BPAD) and alcohol dependency syndrome (ADS) were included in this study. The clinical pharmacist scrutinized the patients for their participation in the study. Included patients were followed up on monthly basis for up to 4 months. Pharmacotherapy management was provided to the enrolled patients. Interventions provided were discussed with the psychiatrist. Descriptive analysis was performed for categorical variables. RESULTS A total of 84 geriatric patients were enrolled in the study. Majority of the enrolled patients were female (n = 46, 54.7%). Nearly half of the patients were illiterate (n = 40, 47.6%) and unemployed (n = 38, 45.2%). Among the enrolled patients, half of the study participants were diagnosed with depression (63.09%) followed by BPAD (27.38%), Schizophrenia (7.14%), and ADS (2.38%). A total of 155 medication information services were provided to 84 patients including patient counseling (n = 84, 100%), pharmacist interventions (n = 48, 30.96%) and medication information (n = 23, 14.83%). Most of the interventions were adverse drug reactions followed by drug-drug interactions, failure to receive drugs, untreated indication, subtherapeutic dose, drug use without indication, and overdose. Majority of the interventions (n = 46, 95.8%) provided were accepted by the psychiatrist. CONCLUSION The study findings indicate that pharmacotherapy management services provided by the clinical pharmacist in collaboration with the psychiatrist benefited the geriatric psychiatric patients.

Abstract
BACKGROUND Convalescent plasma has been widely used to treat COVID-19 and is under investigation in numerous randomized clinical trials, but results are publicly available only for a small number of trials. The objective of this study was to assess the benefits of convalescent plasma treatment compared to placebo or no treatment and all-cause mortality in patients with COVID-19, using data from all available randomized clinical trials, including unpublished and ongoing trials (Open Science Framework, https://doi.org/10.17605/OSF.IO/GEHFX ). METHODS In this collaborative systematic review and meta-analysis, clinical trial registries (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform), the Cochrane COVID-19 register, the LOVE database, and PubMed were searched until April 8, 2021. Investigators of trials registered by March 1, 2021, without published results were contacted via email. Eligible were ongoing, discontinued and completed randomized clinical trials that compared convalescent plasma with placebo or no treatment in COVID-19 patients, regardless of setting or treatment schedule. Aggregated mortality data were extracted from publications or provided by investigators of unpublished trials and combined using the Hartung-Knapp-Sidik-Jonkman random effects model. We investigated the contribution of unpublished trials to the overall evidence. RESULTS A total of 16,477 patients were included in 33 trials (20 unpublished with 3190 patients, 13 published with 13,287 patients). 32 trials enrolled only hospitalized patients (including 3 with only intensive care unit patients). Risk of bias was low for 29/33 trials. Of 8495 patients who received convalescent plasma, 1997 died (23%), and of 7982 control patients, 1952 died (24%). The combined risk ratio for all-cause mortality was 0.97 (95% confidence interval: 0.92; 1.02) with between-study heterogeneity not beyond chance (I2 = 0%). The RECOVERY trial had 69.8% and the unpublished evidence 25.3% of the weight in the meta-analysis. CONCLUSIONS Convalescent plasma treatment of patients with COVID-19 did not reduce all-cause mortality. These results provide strong evidence that convalescent plasma treatment for patients with COVID-19 should not be used outside of randomized trials. Evidence synthesis from collaborations among trial investigators can inform both evidence generation and evidence application in patient care.

Abstract
A rapid and increasing spread of COVID-19 pandemic disease has been perceived worldwide in 2020. The current COVID-19 disease outbreak is due to the spread of SARS-CoV-2. SARS-CoV-2 is a new strain of coronavirus that has spike protein on the envelope. The spike protein of the virus binds with the ACE-2 receptor of the human lungs surface for entering into the host. Therefore, the blocking of viral entry into the host by targeting the spike protein has been suggested to be a valid strategy to treat COVID-19. The patients of COVID-19 were found to be asymptomatic, cold, mild to severe respiratory illness, and leading to death. The severe illness has been noted mainly in old age people, cardiovascular disease patients, and respiratory disease patients. However, the long-term health effects due to COVID-19 are not yet known. Recently, the vaccines were authorized to protect from COVID-19. However, the researchers have put an effort to discover suitable targets and newer medications in the form of small molecules or peptides, based on in-silico methods and synthetic approaches. This manuscript describes the current perspectives of the causative agent, diagnostic procedure, therapeutic targets, treatment, clinical trials, and development of potential clinical candidates of COVID-19. The study will be useful to identify the potential newer medications for the treatment of COVID-19.

Abstract
The surge of coronavirus disease 2019 (COVID-19) hospitalizations at our 877-bed quaternary care hospital in Detroit led to an emergent demand for Infectious Diseases (ID) consultations. The traditional one-on-one consultation model was untenable. Therefore, we rapidly restructured our ID division to provide effective consultative services. We implemented a novel unit-based group rounds model that focused on delivering key updates to teams and providing unit-wide consultations simultaneously to all team members. Effectiveness of the program was studied using Likert-scale survey data. The survey captured data from the first month of the Detroit COVID-19 pandemic. During this period there were approximately 950 patients hospitalized for treatment of COVID-19. The survey of trainees and faculty reported an overall 95% positive response to delivery of information, new knowledge acquisition, and provider confidence in the care of COVID-19 patients. This showed that the unit-based consult model is a sustainable effort to provide care during epidemics.

Motivation COVID-19 has several distinct clinical phases: a viral replication phase, an inflammatory phase, and in some patients, a hyper-inflammatory phase. High mortality is associated with patients developing cytokine storm syndrome. Treatment of hyper-inflammation in these patients using existing, approved therapies with proven safety profiles could address the immediate need to reduce mortality. Results We analyzed the changes in the gene expression, pathways and putative mechanisms induced by SARS-CoV2 in NHBE, and A549 cells, as well as COVID-19 lung vs. their respective controls. We used these changes to identify FDA approved drugs that could be repurposed to help COVID-19 patients with severe symptoms related to hyper-inflammation. We identified methylprednisolone (MP) as a potential leading therapy. The results were then confirmed in five independent validation data sets including Vero E6 cells, lung and intestinal organoids, as well as additional patient lung sample vs. their respective controls. Finally, the efficacy of MP was validated in an independent clinical study. Thirty-day all-cause mortality occurred at a significantly lower rate in the MP-treated group compared to control group (29.6% vs. 16.6%, p = 0.027). Clinical results confirmed the in silico prediction that MP could improve outcomes in severe cases of COVID-19. A low number needed to treat (NNT = 5) suggests MP may be more efficacious than dexamethasone or hydrocortisone.

Abstract
Treatment options for severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) are limited with no clarity on efficacy and safety profiles. We performed a systematic review and meta-analysis of studies on patients ≥18 years reporting data on therapeutic interventions in SARS-CoV-2. Primary outcome was all-cause mortality and secondary outcomes were rates of mechanical ventilation, viral clearance, adverse events, discharge, and progression to severe disease. Pooled rates and odds ratios (OR) were calculated. Twenty-nine studies with 5207 patients were included. Pooled all-cause mortality in intervention arm was 12.8% (95% confidence interval [CI]: 8.1%-17.4%). Mortality was significantly higher for studies using hydroxychloroquine (HCQ) for intervention (OR: 1.36; 95% CI: 0.97-1.89). Adverse events were also higher in HCQ subgroup (OR: 3.88; 95% CI: 1.60-9.45). There was no difference in other secondary outcomes. There is a need for well-designed randomized clinical trials for further investigation of every therapeutic intervention for further insight into different therapeutic options.

Abstract
Introduction: Hyperpigmentary disorders, a common skin disorder affecting individuals with darker skin especially Asians, Blacks, Hispanics and American Indians, has a great impact on patient’s Quality of Life (QOL) with physical distress and psychological impact, and studies have shown that there is an improvement in QOL after treatment. The topical medications include sunscreens, demelanising agents, immunomodulators like tacrolimus, retinoids and Glucocorticoids (GCs). Systemic therapy includes GCs and antioxidants. Physical therapy includes chemical peels, microderma abrasion, Laser and light therapies and mesotherapy. Aim: To determine the pattern of drug use in hyperpigmentary disorders, to assess the tolerability of therapy and to analyse the effect of hyperpigmentary disorders of skin to the prescribed medications on the QOL before and after treatment. Materials and Methods: This was a prospective, observational study conducted on 102 newly diagnosed and untreated participants with hyperpigmentary disorders, who attended Dermatology Outpatient Department of a tertiary care hospital, Bangalore, India. The pattern of drug therapy, route of administration and Adverse Events (AEs) to the therapy was documented and analysed using descriptive statistics. The QOL using Dermatology Life Quality Index (DLQI) was assessed before and after treatment using Analysis of Variance (ANOVA). The patients were monitored every 30 days for three months to study the appropriateness, changing trends in prescription pattern, tolerability and QOL. Results: A total of 102 participants were enrolled for the study. The mean age was 33.71±10.68 years in males and 34.07±10.27 years in females. The different classes of drugs used were demelanising agents, sunscreens, antifibrinolytics, calcineurin inhibitors, keratolytics, glucocorticoids. The number ranged from 2-4 drugs per participant with a mean of 3.01±1.01. A significant improvement in the QOL was observed after treatment (p-value <0.01). Most of the AEs were self limiting except a few (acneiform eruption, rosacea) which were topical GCs induced. Conclusion: The individualised prescription pattern by treating physician was in concurrence with the standard line of therapy as they fulfilled the desired objectives. Hydroquinone (HQ), tranexamic acid and triple formula were the mainstay of treatment. The QOL improved after treatment.

Abstract
Background Convalescent plasma (CP) has been described as a potential therapy for coronavirus disease 2019 (COVID-19). Given paucity of data, we sought to describe characteristics of CP recipients in survivors and non-survivors. Methods We conducted retrospective review of electronic medical records which included any patient with a positive SARS-CoV-2 PCR test who received CP at an 890-bed quaternary care hospital in Southeast Michigan between March-May 2020. Data collected included: demographics, co-morbidities, mSOFA score on admission, laboratory values, and treatment. Outcomes assessed included inflammatory markers and clinical status based on an 8-point ordinal scalea. These values were recorded on admission, the date of CP (day 1), day 3, 7, and day 30 post-CP. Patient outcomes were stratified by ordinal scale score and compared using Mann-Whitney U tests to examine differences in clinical characteristics: scale of 1–4 (“meaningful survivor”), 5–7 (“survivor”), and 8 (“non-survivor”). Results Results of our study are summarized in Table 1 and 2. Non-survivors were older than survivors (62 vs 71 years; p=0.026). There was no statistically significant difference between patient gender, race, number of days from positive PCR test to CP, treatments, and co-morbidities. There was a trend toward higher mSOFA score on admission in non-survivors (p=0.056). A lower ordinal scale score on the date of receiving CP was significantly associated with meaningful survivorship (6 vs 7, p=0.005).

Comparisons of Outcomes Based on Ordinal Scale at Day 30 ![]()
Conclusion Patients who have a lower ordinal scale score on the date of CP administration are most likely to have meaningful survivorship at day 30. Future studies should evaluate optimal timing and outcomes for CP therapy in COVID-19. Disclosures All Authors: No reported disclosures

Abstract
Background The surge of COVID-19 cases overwhelms hospital systems necessitating rapid learning of the disease process and management. During the course of a novel pandemic, multiple interventions are rapidly implemented to improve patient outcomes. When evaluating efficacy of individual interventions, one should account for the simultaneous improvements in knowledge and experience of healthcare providers (HCP), known as the maturation effect. We hypothesized that multiple processes rapidly implemented, along with the maturation effect would result in improved survival of COVID-19 patients hospitalized over the course of the pandemic. Methods This retrospective study was done at Henry Ford Hospital (HFH), a 900-bed tertiary care facility in Detroit, Michigan. The first COVID-19 patient was hospitalized on March 10, 2020 followed by a rapid surge of cases. We evaluated the trends of in-hospital case fatality rate of COVID-19 PCR positive patients through April 28, 2020. Time-points of sequential implementation of key measures for the management of COVID-19 patients were recorded. Results A total of 1023 COVID-19 patients were hospitalized during the study period with 165 deaths (16 %). Case fatality rate during week one was 42% and down trended over time (Figure 1). Key measures were sequentially implemented over the course of the study period as shown in Figure 1. These included development and implementation of in-house PCR testing, dedicated infectious diseases COVID-19 rounding teams, treatment guidelines and algorithms, and early steroid use in hypoxic patients. Figure 2 demonstrates that despite the surge of COVID-19 admissions, mortality continued to improve over time. Figure 1. Trend line of all-cause in-house morality over time ![]()
Figure 2. Mortality by admission date over time ![]()
Conclusion Maturation effect takes into consideration that regardless of individual interventions, HCP improve their knowledge of the disease process and treatment over time leading to better outcomes. Our study shows the possibility of the maturation effect leading to improved survival in hospitalized COVID-19 patients. The maturation effect should be accounted for when evaluating the effect of specific interventions for COVID-19. Disclosures Marcus Zervos, MD, Melinta Therapeutics (Grant/Research Support)

Abstract
Abstract
Background
The clinical spectrum of the novel corona virus disease 2019 (COVID-19) ranges from mild to severe disease and death. We aim to construct a simple and novel scoring model that will predict mortality events in hospitalized COVID-19 patients.
Methods
We established a retrospective cohort of 2541 patients admitted with COVID-19 from February 19, 2020 to April 28, 2020 to Henry Ford Health System, MI. Sociodemographic data, comorbidities, and clinical data were collected. Our novel SAS score was constructed using 3 easily available parameters, namely Sex, Age, and Oxygen Saturation at presentation (Table 1 and 2). Primary endpoint was mortality. Multivariate analysis with logistic regression was done and the model was assessed using receiver operating characteristic (ROC) with area under ROC (AUROC) to determine the optimal cutoff for sensitivity, specificity, and positive and negative predictive values.
Results
The mean age of survivors was 61 compared to 75 years for non-survivors (standard deviation 16 vs 13.8, p< 0.0001), and 1298 (51.1%) were men. Multivariate analysis of the SAS score adjusted for modified SOFA [Sequential organ failure assessment] score (mSOFA) showed that age (odds ratio [OR] 2.4, 95% confidence interval {CI} 2.04–2.72, p< 0.0001) and oxygen saturation (OR 1.6, 95% CI 1.27–1.98) were the most significant predictors of mortality in the model. The SAS score had an AUROC of 0.78 (95% CI 0.77–0.81) (Figure 1). A cutoff score of 3 offered the most sensitivity for predicting mortality while maintaining a negative predictive value of 95% (Table 3). Comparison of AUROC shows that SAS score adjusted to mSOFA has better diagnostic information compared to either SAS score or mSOFA alone (Figure 2).
Conclusion
The easy to use SAS score at time of presentation identified hospitalized COVID-19 patients at high risk for mortality. Application of the SAS score in the emergency department may help triage patients to inpatient versus outpatient care.

Abstract
Background Pneumothorax has been reported with the use of positive pressure ventilation in COVID-19 pneumonia. Literature on spontaneous pneumothorax (PTX) in COVID-19 patients is scant. We present a case series of 7 patients with COVID-19 pneumonia, who developed spontaneous pneumothorax without prior mechanical ventilation. Methods A retrospective chart review of 7 cases was performed from two different hospitals in the US between 4/6/2020–5/15/2020. Hospitalized patients with confirmed COVID-19 by nasopharyngeal RT-PCR who developed spontaneous pneumothorax were included. Collected data included demographics, co-morbidities, inflammatory biomarkers, chest imaging and management strategies. Length of stay, transfer to intensive care unit and death were the assessed outcomes. A descriptive analysis was done. Results There were 3 patients from Henry Ford Health System, Michigan and 4 patients from Silver Cross Hospital, Illinois. Median age was 75 years and 6 out of 7 (85.7%) were males (Table 1). There were no co-morbidities associated with spontaneous pneumothorax except for one patient with COPD. None of the patients’ imaging prior to diagnosis of pneumothorax revealed any underlying blebs. Median time from symptom onset to diagnosis of pneumothorax was 17 days. One of the patients had tension pneumothorax, two had bilateral pneumothorax and three had pneumomediastinum (Figure 1). Four patients required chest tube placement, three required escalation to ICU, of which two died. Table 1. Demographics and Clinical Characteristics of Patients with Spontaneous Pneumothorax ![]()
Figure 1. CT imaging before (left) and after (right) Spontaneous Pneumothorax ![]()
Conclusion Spontaneous pneumothorax may be an unrecognized late complication of COVID-19 pneumonia. In hospitalized patients with acute respiratory decompensation, spontaneous pneumothorax should be considered as part of the differential diagnosis. Repeat chest imaging should be considered in these cases. Disclosures All Authors: No reported disclosures

Abstract
Self-medication practices of type 2 diabetes in India include the use of both traditional and western medications. It is important to understand the factors influencing self-medication. A total of 3257 studies were screened and nine studies (six quantitative and three qualitative) were included. The Hawker tool and Joanna Briggs Institute Critical Appraisal tool were used to assess the quality of studies. The findings of the quantitative studies were descriptively analysed while thematic analysis was performed to identify key themes from the qualitative studies. The analysis indicated that participants had greater trust in traditional medications regardless of their socioeconomic and/or educational backgrounds as these were often recommended by friends and family members. Low cost, ease of availability and perceived lower side effects of traditional medications were some of the factors contributing to greater trust. It is suggested that ongoing management of type 2 diabetes requires stringent policies and regulations in the dispensing of traditional and western medications. Continual education to inform people on the use of self-medications and its possible adverse effects is also required.

Abstract
Pathogenic novel coronavirus SARS-CoV-2 is a recently rising infection that causes a high death rate in contaminated individuals. Many of the individuals who are infected are unaware of the infection because they may be asymptomatic carriers of the virus.To early analyze the viral disease, we proposed advancement of SARS-CoV-2 spike (S) proteins-explicit polyclonal antibodies-based kit described in this specific circumstance. The tests, if made accessible from variety of makers, can help smooth out early immunodetection of the crown viral infection. The survey Safe and Patient Friendly Healthcare suggests early diagnosis as the key to patients recovering from this deadly ailment.
