Probiotic Formulations: A Patent Landscaping Using the Text Mining Approach.

The outstanding research outcomes and registrations of myriads of probiotic strains have flooded the health market with various innovative probiotic-based products and their patents. The study of patented formulations of probiotics can give an overall insight into its existing application. A landscaping review of patents for probiotic-based preparations is presented in the current work. The patent search was performed over commercially available patent databased and analysis tool-PatSeer Pro®. Search strings containing words "Formulation" and "Composition" resulted in more than 3700 patents. Landscaping review of 400 + patents from the last 20 years (2000-2020) was performed using the Text-Mining approach. Text-Mining helped to identify 19 technological clusters which represent these patents. These clusters include the patents of probiotic preparations on animal feed, human food, cosmetics, antimicrobial, antidiabetic, arthritis, etc. A review of this massive number of patents unveiled many exciting preparations. Probiotic-based innovative products for depression, diabetes, Parkinson's, tumor, acne, and animal husbandry are reviewed comprehensively. The present work also unravels a few new-flanged products like probiotic layered condoms, products for acute alcoholism, and traditional Chinese medicine with probiotics. The patent landscape of probiotic-based preparations has presented a whole scenario of probiotic-based preparations. It has also revealed many unexplored areas where innovation can be excelled.

Painless Subacute Thyroiditis in a Patient With Acute COVID-19 Infection: A Transient Event.

Coronavirus 2019 disease (COVID-19) is a highly contagious infectious disease caused by severe acute respiratory coronavirus 2 (SARS-CoV-2). Although several articles have described the non-respiratory effects of COVID-19 in the past two years, there are few reports of COVID-19 associated with thyroiditis. We present a case of a middle-aged female patient with positive COVID-19 PCR associated with acute pulmonary embolism and thyroiditis. Three months ago, her baseline thyroid profile was normal. Thyroiditis induced elevated free thyroxine (FT4) and decreased thyroid-stimulating hormone (TSH) levels resolved with conservative management within six days.

Diabetic Ketoacidosis and COVID-19: A Case Series From an Inner-City Community Teaching Hospital in New York.

INTRODUCTION: Throughout the coronavirus disease 2019 (COVID-19) pandemic, studies have repeatedly shown that COVID-19 outcomes are more severe in the elderly and those with comorbidities, with diabetes being a significant risk factor associated with more severe infection. Here, we present the clinical characteristics of 25 patients with pre-existing type 2 diabetes mellitus who presented with diabetic ketoacidosis (DKA) and COVID-19 in a community hospital in Brooklyn, New York, and identify possible predictors of mortality. METHODS: This retrospective case series recruited patients from March 1st to April 9th, 2020, with lab-confirmed COVID-19 and met DKA criteria on admission (based on American Diabetes Association diagnostic criteria for DKA). RESULTS: Of the 25 patients who met the inclusion criteria, 22 were African American and three were Hispanic. Common comorbidities in addition to diabetes were hypertension, obesity, coronary artery disease, and dyslipidemia. Fever, cough, myalgias, and shortness of breath were common presenting symptoms. Most patients had elevated inflammatory markers erythrocyte sedimentation rate, C-reactive protein, D-dimer, and ferritin, but higher values increased the odds of mortality. The overall survival was 64%, with those recovering having more extended hospital stays but requiring less time in the intensive care unit. At the same time, those who died were more likely to require mechanical ventilation, have an acute cardiac injury, and/or be obese. Despite numerous studies on COVID and diabetes, only a few studies described DKA. CONCLUSION: This observational retrospective study illustrated that patients with diabetes are at risk of developing DKA with COVID-19 and identified some predictors of mortality. However, further studies with larger sample sizes and a control group are necessary to understand better the effects of COVID-19 on DKA and their clinical outcomes.

Acute COVID-19-Associated Cardiac Arrhythmia: A Case Series and Literature Review.

Coronavirus disease 2019 (COVID-19) is a highly contagious infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report two cases of COVID-19-associated atrial fibrillation (AF) in two elderly females and a case of atrial flutter (AFlutter) in a middle-aged male patient. We believe this case series will contribute to the literature on new-onset AF and AFlutter in patients with acute COVID-19 infection. This case series illustrates various case scenarios of patients developing cardiac arrhythmia with acute COVID-19 infection without any prior history or other explicable cause of AF/AFlutter. The exact mechanism behind COVID-19 infection leading to AF or AFlutter is still unknown. Of the three patients reported, two converted to sinus rhythm following medical management, and one did not convert to sinus rhythm despite medical treatment.

A Case of Bilateral Hemorrhagic Pleural Effusion Due to Dual Antiplatelet Therapy in a Dialysis Patient.

Etiologies of hemorrhagic pleural effusions (hemithoraces) are multifactorial. They can be traumatic, non-traumatic, or idiopathic in nature. In this report, we present a rare case of a 64-year-old male with end-stage renal disease (ESRD) on chronic hemodialysis and dual antiplatelet therapy (DAPT), due to a recent history of coronary arterial stent placement, who presented with progressive shortness of breath for one month. The CT of the chest revealed bilateral large pleural effusions (left > right) with a complete collapse of the left lung and partial collapse of the right lung. Ultrasound-guided left-sided thoracentesis revealed hemorrhagic pleural effusions. After the discontinuation of DAPT, drainage from the right-sided pleural effusion via a pigtail catheter showed continued drainage of pleural fluid without hemorrhage. The effusion on the left side was also noted to have resolved on the repeat chest X-ray. Prompt recognition of this rare cause of any hemorrhagic pleural effusion is essential for patients on dialysis to avoid complications. This report focuses on the possible etiology and potential complications of a hemorrhagic pleural effusion, followed by a brief discussion on the rare but significant association involving the incidence of a hemorrhagic pleural effusion in a dialysis patient receiving DAPT.

Augmented Renal Clearance in a Case of Sepsis Leading to Vancomycin Failure Despite Increasing Dose As per the Estimated Glomerular Filtration Rate.

Augmented renal clearance (ARC) is a unique clinical scenario observed in critically ill patients. We present a case of a 30-year-old male with sepsis secondary to methicillin-resistant Staphylococcus aureus (MRSA) bacteremia treated with vancomycin. ARC was observed in the patient with a maximum estimated glomerular filtration rate (eGFR) of 161.9 ml/min/1.73 m2, and therapeutic drug monitoring was used to adjust the vancomycin dosage. Despite the maximal recommended dose of vancomycin, the therapeutic vancomycin level was not achieved, leading to treatment failure and subsequent mortality. Our case report suggests the necessity of other strategies, such as early dose adjustment of vancomycin based on vancomycin clearance and continuous vancomycin infusion, not merely conventional adjustment based on eGFR and vancomycin levels.

COVID-19 Coronavirus-Induced Atypical Pneumonia: Efficacy of the Monoclonal Antibody Bevacizumab in Moderate to Severe Cases.

COVID-19 novel coronavirus has created a global pandemic. Affected patients may develop acute lung injury and its more severe form - acute respiratory distress syndrome. Hypoxia and severe inflammation increase the production of vascular endothelial growth factor (VEGF), which induces vascular endothelial proliferation. Administration of the anti-VEGF monoclonal antibody bevacizumab is proposed for usage in moderate to severe pneumonia. We aim to present two cases of COVID-19 induced atypical pneumonia, which were treated with the anti-VEGF monoclonal antibody bevacizumab.

Clinical and Radiological Dissociation in Massive Barium Aspiration.

Barium studies are commonly used to rule out gastrointestinal (GI) pathologies and sometimes they are associated with complications such as barium aspiration with heterogeneity in clinical features ranging from mild to severe symptoms. We present a case of large volume barium aspiration in a 73-year-old male with past medical history of dysphagia diagnosed with diffuse esophageal spasm. Barium is an inert material commonly used for GI tract study. Although complications associated with barium studies are rare, aspiration of barium can have dramatic findings resulting in mild to severe symptoms. Clinically patient had very minimal symptoms but radiographic studies appeared dramatic. Therefore, a clinical and radiographic paradox must be kept in mind when evaluating patients and reviewing large volume barium aspiration imaging. Our case remained asymptomatic and had no respiratory complaints, nor did he develop any respiratory distress post barium aspiration.

Ketamine infusion as a sedative-analgesic in severe ARDS (KISS).

RATIONALE: Ketamine has been used as a sedative analgesic in trauma setting, but data regarding its efficacy and safety is lacking in severe ARDS. This retrospective study aims to determine if Ketamine is safer as a sedative agent in mechanically ventilated patients. During the COVID pandemic, as there was a shortage of sedative agents, Ketamine was used. OBJECTIVES: The primary objective was to compare the safety of ketamine to other sedatives. The secondary objective was to compare the effect of ketamine to other sedatives regarding the need for vasopressor, incidence of delirium, infectious complications, acute kidney injury, hospital length of stay, and length of ventilator days. METHODS: A retrospective, observational cohort study was conducted. MEASUREMENTS AND MAIN RESULTS: One hundred and twenty-four patients (63 men and 61 women) were included. Thirty-four patients received ketamine, while 90 patients received other traditionally used sedatives such as propofol and midazolam. The patients' median age was 64 years in the ketamine group and 68 years in the non-ketamine group. Seventeen patients in the ketamine group (50%) and 65 patients (72%) in the non-ketamine group had mortality (p < 0.02). The hospital length of stay was 22.85 days (± 16.36) in the ketamine group and 15.62 days (± 14.63) in the non-ketamine group (p < 0.02). There was no statistically significant difference among the outcomes of the need for vasopressor, the incidence of delirium, infectious complications, and acute kidney injury. CONCLUSIONS: Ketamine as a sedative-analgesic agent in COVID-19 patients with severe acute respiratory distress syndrome demonstrated safety with reduced mortality. The ketamine group had a higher hospital length of stay, but a similar complication profile compared to the non-ketamine group. Further prospective randomized controlled trials are warranted to confirm these findings.
