Socioeconomic Disparities and Emergency Department Visits for Diabetic Retinopathy in California.

Purpose: To investigate the association between neighborhood-level socioeconomic factors, quantified by the Distressed Communities Index, and emergency department visits for diabetic retinopathy (DR). Methods: All patients who presented to the emergency department for DR in California were analyzed using the State Emergency Department Database (2018-2020). Patients were stratified by Distressed Communities Index score and DR severity. Logistic regression was applied to explore the independent correlation between Distressed Communities Index scores and proliferative DR (PDR). Results: Of 2 725 195 emergency department visits for diabetic patients, Distressed Communities Index data were available for 2 459 577 (90.3%); 39 693 were for DR, including 13 617 (34.3%) for PDR. Hispanics (44.2%) were the largest racial/ethnic group to present for PDR, followed by non-Hispanic Whites (19.6%) and non-Hispanic Blacks (19.3%). A significant association was observed between the Distressed Communities Index and emergency department visits for PDR, with distressed neighborhoods having the highest incidence (adjusted odds ratio [aOR], 1.63; 95% CI, 1.20-2.23; P = .001). Other predictors included Hispanic ethnicity (aOR, 2.21; 95% CI, 1.97-2.48; P < .001) and Black race (aOR, 1.46; 95% CI, 1.28-1.67; P < .001) compared with White race and having Medicaid (aOR, 1.37; 95% CI, 1.13-1.65; P = .001) compared with private insurance. Conclusions: The Distressed Communities Index identified patients residing in the most distressed neighborhoods as being at the highest risk for presenting to the emergency department for PDR based on 7 socioeconomic factors. Policymakers may consider the Distressed Communities Index as a tool for targeting DR prevention strategies and improving healthcare accessibility.

Effectiveness of Telemedicine in Controlling Hyperglycemia Among Diabetic Patients on Insulin Therapy in Primary Care: A Systematic Review and Meta-Analysis.

This study investigates the effectiveness of telemedicine in managing glucose levels in insulin-treated diabetes patients compared to standard care. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) criteria and Cochrane's risk of bias tool, an analysis of five selected studies reveals telemedicine as a potent tool in diabetes management. Fasting blood sugar (FBS) test results from two studies involving an eight-hour fast with 109 participants demonstrate a significant superiority of telemedicine over usual care (Tau2 = 1.63; Chi2 = 1.01, df = 1, P = 0.32; Z = 2.43, P = 0.02), highlighting its potential in short-term blood sugar stabilization. Postprandial plasma glucose (PPBG) test outcomes suggest comparable efficacy in managing post-meal blood glucose levels with telemedicine. Additionally, analysis of glycated hemoglobin (HbA1c) levels across all five studies indicates telemedicine's equivalence to traditional care in maintaining HbA1c levels among insulin-treated patients, affirming its efficacy in primary care. While emphasizing telemedicine's effectiveness in managing FBS levels, a critical aspect of diabetes control, among patients utilizing insulin therapy in primary care, the study underscores the need for more extensive, large-scale research to fully comprehend its impact on diabetes management.

Type 1 Diabetes Mellitus Management and Islet Cell Therapy: A New Chapter in Patient Care.

Diabetes mellitus (DM) is a complex endocrine disorder characterized by abnormally high levels of glucose, also called hyperglycemia. DM usually occurs when the body does not produce enough insulin or cannot respond to the insulin in the body. Type 1 diabetes mellitus (T1DM) or insulin-dependent diabetes is an autoimmune disease that affects around 8 million people in the world. Patients with T1DM experience an array of symptoms such as polyuria, polydipsia, and weight loss. These patients are prone to immediate life-threatening complications, including hypoglycemia and diabetic ketoacidosis. These patients are also at increased risk of ischemic heart disease, stroke, chronic kidney disease, vision loss, and even damage to nerve endings resulting in neuropathy. In this article, we will discuss type 1 diabetes mellitus and the different treatment options, focusing primarily on the Food and Drug Administration (FDA)-approved first cellular therapy for T1DM, donislecel.

From Symptomatic Treatment to Disease Modification: A Turning Point in Alzheimer's Disease Management.

Alzheimer's disease (AD) is a neurodegenerative disease primarily affecting individuals aged 65 or above. AD leads to progressive cognitive and functional decline, affecting daily life activities. Amyloid plaques are the pathological hallmark of AD, resulting in the loss of neurons and their connections in the brain. For years, patients with AD were treated with pharmacotherapies having only symptomatic effects. Till 2023, no drug was approved for disease-modifying potential. The Food and Drug Administration approved Lecanemab and aducanumab as the first therapy with disease-modifying effects in 2023. Lecanemab has shown efficacy in several trials, with the potential to improve cognition in AD patients. In this article, we will discuss the treatment options for AD, emphasizing the newly approved monoclonal antibodies and their prospects.

Co-Aggregative Effect of Probiotics Bacteria against Diarrheal Causative Bacteria.

Probiotics have been used for over a century to prevent and treat diseases. They can reduce the effects of gastroenteritis and are now used to treat acute diarrhea. This study aimed to evaluate the co-aggregative effects of probiotics bacteria against diarrheal causative bacteria. For this purpose, 11 isolates of probiotic bacteria were used in the current study, including three Lactobacillus plantarum, one Lactobacillus gasseri, two Lactobacillus fermentum, three Lactobacillus acidophilus, and two Lactococcus garvieae isolates. All isolates were tested for antibiotic susceptibility, autoaggregation ability, adhesion ability, antibacterial activity, acid tolerance, and bile salts tolerance. The results showed that most of them had the ability to autoaggregate after 4 h, with the highest percentage of 57.14% for L. fermentum. For the antibiotic susceptibility test, all the isolates showed resistance against trimethoprim/sulfamethoxazole, except one isolate. Moreover, all the isolates, except one, were susceptible to both vancomycin and tetracycline. All tested isolates had adhesion ability with different survival rates, which reached 34.57% for L. plantarum in acidic conditions. Besides, the highest survival rate was 85.17%, which belonged to L. garvieae, for bile salt tolerance. Probiotic isolates had an antibacterial effect against diarrhea-causative bacteria with an inhibition diameter of 17-49 mm for different Lactobacillus spp. and Lactococcus spp. isolates. Furthermore, the co-aggregation ability of probiotic isolates against diarrhea-causative bacteria was studied, and results showed that probiotic isolates had a co-aggregative effect against diarrhea-causative bacteria, Escherichia coli, Shigella sonnei, and Providencia alcalifaciens, after 24 h of incubation. The highest co-aggregative effect of probiotics isolates belonged to L. fermentum and L. acidophilus against P. alcalifaciens with a co-aggregation percentage of 100%, while the lowest co-aggregation rate was 14.29% against E. coli. The findings revealed the probiotic properties and co-aggregative effects of probiotic bacteria against diarrhea-causative bacteria.

Neovascular Age-Related Macular Degeneration in a Predominantly Black Population.

BACKGROUND AND OBJECTIVE: We intend to study the characteristics and outcomes of an understudied patient population with neovascular age-related macular degeneration (nAMD). PATIENTS AND METHODS: This retrospective study evaluated presenting features and outcomes in a predominantly Black patient population with nAMD. A multivariate regression explored baseline characteristics predictive of 1-year vision. RESULTS: Sixty-three eyes were included. The median (interquartile range) baseline vision was 20/300 (20/80 to counting fingers). Patients' baseline optical coherence tomography findings showed a mean central subfield thickness of 336 µm; 80% (n = 35) and 41% (n = 18) had fluid and central scarring, respectively. The primary predictor for vision at year-one was baseline vision (P = 0.03, 95% CI: 0.04 to 0.91). All of those who gained ≥ 3 lines of vision lacked central scarring at baseline. CONCLUSION: Further studies are needed to investigate how to improve earlier detection and treatment of nAMD in this patient population. [Ophthalmic Surg Lasers Imaging Retina 2023;54:580-584.].

The Role of Anticoagulants and Antiplatelets in Reducing Mortality in COVID-19 Patients: A Systematic Review and Meta-Analysis of Studies Reporting Adjusted Data.

The coronavirus disease 2019 (COVID-19) is associated with prolonged prothrombin time (PT), active partial thromboplastin time (aPTT), and increased D-dimer levels. Therefore, we aim to investigate if anticoagulants (AC) and antiplatelet (AP) therapy play a role in mitigating COVID-19 and its associated thrombosis along with its effect on the mortality rate, the need for mechanical ventilation, and the risk of hospital admission. Electronic databases were searched from their inception to July 19, 2022. The studies were divided into two groups: Group A (any dose of AC/AP versus no AC/AP) and Group B (therapeutic dose of AC (tAC)/AP versus prophylactic dose of AC (pAC)/AP). Review Manager (RevMan) version 5.4.1 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark) was used for all statistical analyses. Adjusted data ratios were extracted from all included studies and pooled using the random effects model. A total of 33 studies were taken for the analysis of two groups (Group A: 285,065 COVID-19-positive patients, Group B: 2,421 COVID-19-positive patients). Overall analysis in Group A showed that the AC/AP group had a low risk of mortality in COVID-19 patients compared to the control group (risk ratio (RR): 0.77, 95% confidence interval (CI): 0.69-0.86). There was no significant difference in the need for mechanical ventilation (RR: 0.80, 95% CI: 0.60-1.08) and hospital admission (RR: 1.12, 95% CI: 0.78-1.59) between the AC/AP and no AC/AP group. Alongside, in Group B, tAC/AP did not demonstrate a significant decrease in mortality as compared to pAC/AP (RR: 0.62, 95% CI: 0.37-1.06). Treatment with AC and AP drugs can significantly decrease the mortality rate in COVID-19-infected patients, while AC also significantly reduces the need for mechanical ventilation.

A Rare Presentation of Colon Carcinoma Metastasis Within a Meningioma: A Case Report and Literature Review.

Colon carcinoma with brain metastasis is a rare presentation. This presentation is more unusual and unique when the single brain metastatic lesion has two different types of tumors. This rare phenomenon is known as a tumor-to-tumor metastasis. A meningioma usually hosts lung and breast cancers within it. However, colon carcinoma metastasis into meningiomas has rarely been reported. An 86-year-old man presented with neurological symptoms and was found to have a brain mass. The search for primary lesions was negative as the chest, abdomen, and pelvis CT scan was insignificant. When the brain lesion's pathology revealed a composite mass of adenocarcinoma and a meningioma, further investigation with a colonoscopy revealed a colonic mass as the primary metastasis lesion. This unique presentation and pathology emphasize the importance of a comprehensive investigative approach to finding the primary lesions and consideration of such a phenomenon in these lesions.

Pakistan's Healthcare System: A Review of Major Challenges and the First Comprehensive Universal Health Coverage Initiative.

Each country's healthcare system has a different structure and functioning designed to meet the needs of its people utilizing the available resources. Due to ever-growing population needs and constantly emerging public health problems, it is vital for any healthcare system to be ready to adapt, recognize its limitations, and improve its flaws by learning from other healthcare models across the globe. In this article, we analyzed the significant challenges faced by Pakistan's healthcare system (PHS) and the first comprehensive initiative taken for universal health coverage in Pakistan. Inequitable distribution of resources, inadequate healthcare spending, non-adherence to preventative healthcare and brain drain are the major problems in the PHS. On the other hand, the recently introduced universal health coverage initiative, the Sehat Sahulat Program (SSP), can be considered one of the biggest achievements of the country's healthcare system.

Respiratory Syncytial Virus Prevention: A New Era of Vaccines.

Respiratory syncytial virus (RSV) is a pathogen that primarily affects the respiratory system, leading to upper and lower respiratory tract infections. Children, individuals aged 60 and above, and individuals with impaired immune systems are more susceptible to developing RSV lower respiratory tract infections (LRTIs), which can result in fatalities in some instances. Symptoms of LRTI include shortness of breath, wheezing, pneumonia, and bronchiolitis. Current management of RSV-LRTI includes conservative and symptomatic treatment. The Food and Drug Administration (FDA) recently approved two vaccines that effectively prevent acute and severe RSV-LRTI requiring hospitalizations. Nirsevimab (Beyfortus) is approved for infants born at 35 weeks of gestation and above. At the same time, RSVPreF3 OA (Arexvy) is recommended for adults aged 60 and older. Both vaccines are effective against the two major strains of RSV and require single doses to induce immunity. In this article, we will discuss the mechanism of action, effectiveness, and side effects of these novel vaccines and their possible impact.

Advancements in Sickle Cell Disease (SCD) Treatment: A Review of Novel Pharmacotherapies and Their Impact on Patient Outcomes.

Sickle cell disease (SCD) is a genetic hereditary blood disease that disrupts normal beta-globin production. Patients with SCD experience a broad range of symptoms ranging from anemia, pain crises, and jaundice to acute coronary syndrome and stroke. SCD has been treated with hydroxyurea since 1998. Three important pharmacotherapies have been approved by the Food and Drug Administration (FDA) in the past few years. L-Glutamine has shown efficacy in reducing vaso-occlusive pain crises and hospitalization. Crizanlizumab has also shown positive outcomes in patients with SCD. Voxelotor has been studied to be effective in improving hemolytic anemia and the quality of life in SCD patients. These drugs can be used alone or in conjunction with hydroxyurea. Trials have shown that these therapies have significant efficacy. The events of pain, hemolytic anemia, vaso-occlusive crises, and hospitalizations have been reduced by using these agents. In this editorial, we will discuss these advanced treatment options for patients with SCD.

Detection of Virulence Factors from Candida spp. Isolated from Oral and Vaginal Candidiasis in Iraqi Patients.

Yeast-like fungi (YLF) of the genus Candida are unicellular microorganisms of relatively large size and rounded shape, aerobes, and belong to conditionally pathogenic microorganisms. The genus Candida includes approximately 150 species, which are classified as Deuteromycetes due to the absence of a sexual stage of development. This study aimed to identify virulence factors from Candida spp. isolated from oral and vaginal candidiasis. Fifty-eight oral and vaginal swab specimens were collected from patients, including (28) oral swabs from children and (30) vaginal swabs from different infected women. All isolates were subjected to direct examination, Morphological tests, Germ tube formation, growth at 45ºC, CHROM agar Candida culture, and VITEK 2 Compact system to ensure this diagnosis. (31) isolates were identified as Candida spp., including (21) (C. albicans (14), C. glabrata (1), C. guilliermondii (2), C. dubliniensis (3), C. parapsilosis (1)) were isolated from oral swabs and (10) isolates includedC. parapsilosis (4), C. albicans (6) were isolated from vaginal swabs. Moreover, these isolates had been detected to have some virulence factors, including phospholipase, esterase, proteinase, coagulase, hemolysin, and biofilm formation. Different species of Candida were isolated and identified from oral and vaginal. Phospholipase (Pz), Esterase (Ez), and Proteinase (Prz) were produced by 19 (61.29%), 16 (51.61%), and 26(83.87%), respectively, out of 31 isolates, whereas. All isolates produce coagulase enzyme except C. dubliniensis, which did not produce coagulase enzyme. All Candida spp. isolates produce hemolysin and biofilm formation in different percentages.

TEMPORAL EFFICACY AND STERILITY TESTING OF POVIDONE-IODINE FROM AN OPEN BOTTLE.

PURPOSE: To investigate the temporal efficacy and sterility of povidone-iodine (PI) against bacteria associated with postinjection endophthalmitis in an in vitro study. METHODS: A single PI bottle was opened and tested for sterility and antibacterial efficacy. Povidone-iodine from the open bottle was inoculated onto a blood agar plate and evaluated for growth 24 hours later to test sterility; this was repeated for five consecutive days. To test for antibacterial efficacy, PI was instilled onto the surface of plates of Staphylococcus , Streptococcus , Enterococcus , Pseudomonas , and Haemophilus species. The plates were then evaluated 24 hours later for a clear zone of inhibition (i.e., no growth) where the PI was placed. This process was repeated for five consecutive days. RESULTS: Sterility testing showed no growth of organisms on the blood agar plates for each of the five days of testing. For antibacterial efficacy testing, zones of inhibition of growth were seen on each plate of bacterial colonies only where PI was placed, for each of the five days of testing. CONCLUSION: In this study, PI from an open bottle maintained its sterility and antibacterial efficacy for five days. These data could help support repeated use of the same bottle, reducing waste and costs for retina practices.

Virtual Ophthalmology Rotation for Visiting Medical Students: An Opportunity to Enhance Diversity in the Workforce.

Introduction We created a virtual rotation to facilitate the exposure of ophthalmology to medical students and serve as a pilot program to help attract students from under-represented in medicine (URM) backgrounds. In addition to the rotation eliminating the financial burdens associated with in-person away rotations, we offered a not-for-credit (i.e., drop-in) option that included sessions outside the typical clinic hours. This option reduced scheduling conflicts as a barrier to enrollment and allowed junior medical students and postgraduates to participate and hopefully further develop an interest in ophthalmology. Methods Before the rotation, participants completed a pre-test and a survey to collect data on learners' backgrounds and interest in applying for ophthalmology residency. The rotation included live lectures, case-based discussions, chart reviews, and guided self-study. Following the rotation, participants completed a post-test and a survey to query applicants on the online rotation's utility and delivery. Results Eleven learners enrolled in the course and completed the prerotation survey and test. Approximately one-third (4/11; 36%) were URM students and two-thirds (7/11; 64%) were female. All responded they were planning to apply for ophthalmology residency. All responded they strongly agreed that the rotation increased their general knowledge in ophthalmology, and 89% (9/11) strongly agreed that it improved their ability to diagnose and manage actual patients. Nearly all (7/8; 87.5%) strongly agreed the rotation provided the opportunity to seek support for the residency application process, and all found the online platform reliable and easy to access. Exam scores improved significantly from pre- to post-tests (60 vs. 79%; p < 0.01). Conclusions The rotation attracted a substantial proportion of URM students. Learners reported that the virtual rotation effectively taught and supported their endeavors to become ophthalmologists. Virtual rotations for visiting students can reduce barriers such as travel, financial costs, and time constraints that might otherwise hinder exposure to specialty training that is not offered or is underrepresented at students' home institutions. Increasing exposure and offering mentorship through this novel platform deserves further study to enhance diversity and inclusion in medicine.

Emergency Department Presentation of Retinal Artery Occlusion.

PURPOSE: To determine how frequently patients who present to an emergency department (ED) with a retinal artery occlusion (RAO) undergo brain imaging and cardiovascular testing and are hospitalized. DESIGN: Retrospective cross-sectional study. PARTICIPANTS: Patients who presented to an ED with an RAO in the National Emergency Department Sample (NEDS), a nationally representative United States database. METHODS: The NEDS was queried to identify patients who presented to an ED with the primary diagnosis of RAO between 2006 and 2014. Patient and hospital characteristics were evaluated, and a multivariable regression was performed to determine predictors of hospitalization. Testing was categorized into 3 groups: (1) brain imaging performed using computed tomography or magnetic resonance; (2) carotid imaging performed using ultrasound, computed tomography, or magnetic resonance; and (3) cardiac testing performed using electrocardiogram or echocardiogram. The number of tests performed for each category was recorded. MAIN OUTCOME MEASURES: Proportions of patients undergoing brain imaging, carotid imaging, or cardiac testing. Rate and predictors of hospitalization. RESULTS: Among 259 343 582 ED visits, 2802 had a primary diagnosis of RAO. Patients were mostly aged ≥65 years (59%) and male (54%). Hypertension (59%), dyslipidemia (36%), and diabetes (20%) were the most common preexisting cardiovascular diseases. Brain imaging, carotid imaging, and cardiac testing were performed in 20.3%, 7.1%, and 23.8% of the patients, respectively; at least 1 test from each of these 3 categories was performed in 4.1% of the patients. Half of the patients were hospitalized. Factors that increased the chances of hospitalization included the following (P < 0.05): age of <45 years; female sex; a history of smoking; presenting to a metropolitan hospital and having giant cell arteritis, carotid artery disease, atrial fibrillation, cardiac valve disease, obesity, dyslipidemia, hypertension, diabetes, and chronic ischemic heart disease. CONCLUSIONS: Most patients who presented to an ED with an RAO did not receive emergency brain imaging, carotid imaging, or basic cardiac testing. A multidisciplinary approach is needed to raise awareness that RAOs should be treated as a precursor of stroke or a stroke equivalent.
