Hydroxytriazenes incorporating sulphonamide derivatives: evaluation of antidiabetic, antioxidant, anti-inflammatory activities, and computational study.

The existent investigation deals with synthesis, characterization, computational analysis, and biological activities of some hydroxytriazene derivatives containing sulphonamide moiety. The compounds were screened for antidiabetic, antioxidant, and anti-inflammatory activities. The antidiabetic activity was assessed using α-glucosidase and α-amylase inhibition assays with IC50 values ranging from 32.0 to 759.13 µg/mL and 157.77 to 340.47 µg/mL while standard drug acarbose showed IC50 values 12.21 and 69.74 µg/mL, respectively. The antioxidant activity was evaluated using DPPH and ABTS radical scavenging assays with IC50 value ranging from 54.01 to 912.66 µg/mL and 33.22 to 128.11 µg/mL, and standard drug ascorbic acid showed IC50 values 29.12 µg/mL and 69.13 µg/mL, respectively. Anti-inflammatory activity was investigated using the carrageenan-induced paw edema method, where percentage inhibition was up to 93.0 and 98.57 for 2 h and 4 h, respectively, and all the compounds were found to exhibit excellent anti-inflammatory activity. Moreover, prediction of activity spectra for substance and molecular docking were also performed. The PASS prediction hypothesized the potential of the compounds for anti-inflammatory activity, and docking results suggested the best binding pose for compounds 1b and 2b with the least energy value from which compounds can be considered as potent COX-2 inhibitors. Furthermore, possible interactions between hydroxytriazene analogues and the targets of antioxidant NADPH oxidase and antidiabetic human maltase-glucoamylase enzyme have been identified. The HOMO and LUMO analysis revealed charge transfer within the compounds. These findings suggested that the synthesized compounds can be potential agents for the treatment of diabetes and inflammation.

Phage therapeutics: from promises to practices and prospectives.

The rise in multi-drug resistant bacteria and the inability to develop novel antibacterial agents limits our arsenal against infectious diseases. Antibiotic resistance is a global issue requiring an immediate solution, including the development of new antibiotic molecules and other alternative modes of therapy. This article highlights the mechanism of bacteriophage treatment that makes it a real solution for multidrug-resistant infectious diseases. Several case reports identified phage therapy as a potential solution to the emerging challenge of multi-drug resistance. Bacteriophages, unlike antibiotics, have special features, such as host specificity and do not impact other commensals. A new outlook has also arisen with recent advancements in the understanding of phage immunobiology, where phages are repurposed against both bacterial and viral infections. Thus, the potential possibility of phages in COVID-19 patients with secondary bacterial infections has been briefly elucidated. However, significant obstacles that need to be addressed are to design better clinical studies that may contribute to the widespread use of bacteriophage therapy against multi-drug resistant pathogens. In conclusion, antibacterial agents can be used with bacteriophages, i.e. bacteriophage-antibiotic combination therapy, or they can be administered alone in cases when antibiotics are ineffective.Key points• AMR, a consequence of antibiotic generated menace globally, has led to the resurgence of phage therapy as an effective and sustainable solution without any side effects and high specificity against refractory MDR bacterial infections.• Bacteriophages have fewer adverse reactions and can thus be used as monotherapy as well as in conjunction with antibiotics.• In the context of the COVID-19 pandemic, phage therapy may be a viable option.

Synthesis, characterization, theoretical prediction of activities and evaluation of biological activities of some sulfacetamide based hydroxytriazenes.

Six new N [(4-aminophenyl)sulfonyl]acetamide based hydroxytriazenes have been synthesized and characterized using elemental analysis, IR, 1H NMR, 13C NMR and MASS spectral analysis. Further, their theoretical predictions for probable activities have been taken using PASS (Prediction of Activity Spectra for Substance). Although a number of activities have been predicted but specifically anti-inflammatory, antiradical, anti-diabetic activities have been experimentally validated which proves that theoretical predictions agree with the experimental results. The object of the Letter is to establish Computer Aided Drug Design (CADD) using our compounds.

A Cross-sectional Cohort Analyses Assessing Response to Levosalbutamol Bronchodilatory Cough Formulations in Outpatient Community Settings of India: 'BUS' analyses.

INTRODUCTION: Cough is significant health problem with greater implication for impaired quality of life. Acute and chronic cough due to infective (viral/bacterial), allergic conditions or bronchial asthma including cough variant asthma are often treated with combination of mucolytics, expectorants and bronchodilators. Bronchodilators reduces cough sensitivity, promotes clearance of cough secretions while reducing protrusive inflammatory mediator release. AIMS AND OBJECTIVES: To further understand the clinical utility and safety of Bronchodilatory cough formulations (BCF) containing Levosalbutamol in real world settings. MATERIAL AND METHODS: A prospective, cross sectional, cohort analyses (Bronchodilatory coUgh formulary Survey, BUS) assessing Levosalbutamol cough formulations utilization at 40 centers involving general and consultant physicians across India. RESULTS: Consecutive prescription records (n=1367) involving Levosalbutamol were collated for analyses. Baseline demographics included adults (21%) and children (79%) with mean age 11.1 yrs, male (60%) and female(40%). Levosalbutamol BCF was commonly prescribed for LRTI (69.7%), AECB (14.8%), Bronchial asthma (8.5%), Allergic rhinitis (5%). The predominant risk factors in both adults and children included smoking and allergic rhinitis respectively. In most cases cough severity was assessed utilizing Fisman scale score (0-4). Mean cough score improved from baseline score of 3 to 0.8 with parallel improvement in associated symptoms of wheeze and sputum. Antibiotics were prescribed in most of LRTI or acute exacerbation cases with purulent sputum. Side effects noted included tremor (1%), palpitation (0.9%), vomiting (0.7%) that were mild and transient in most cases with none requiring treatment withdrawal. In two cases (0.1%), further treatment with nebulization and antibiotics were provided. CONCLUSIONS: Levosalbutamol containing Bronchodilatory Cough formulation remains as safe and effective option for adults and children while managing acute or chronic cough primarily due to allergic rhinitis, bronchial asthma or COPD.

Thyroid inferno.

The key to uncovering the etiology of hyperthyroidism lies in a careful history and physical examination. Autoimmune markers provide additive information, but should not solely be used to make a diagnosis. Concern has been raised that the overzealous use of thyroid ultrasound, following abnormal thyroid function tests, diverts attention from the workup of the biochemical abnormality to the workup of an incidentally found thyroid nodule. If further imaging is needed, the use ofathyroidscanhas been suggestedbythe Endocrine Society and the American Association of Clinical Endocrinologists. However, in certain scenarios, this may be contraindicated. We present the case of a 28-year-old female with hyperthyroidism, as aplatform to discuss an important clinical sign present on Doppler ultrasound of the thyroid. By recognizing the clinical information gained from a Doppler ultrasound, physicians can avoid additional invasive workup and apply the use of ultrasound where most appropriate.

Esophageal perforation after anterior cervical spine surgery.

Objective: To report our updated experience in the management of esophageal perforation resulting from anterior cervical spine surgery, and to compare two wound management approaches. Methods: This is a retrospective review of patients managed for esophageal perforations resulting from anterior cervical spine surgery (2007-2020). We examine outcomes based on 2 wound management approaches: closed (closed incision over a drain) versus open (left open to heal by secondary intention). We collected data on demographics, operative management, resolution (resumption of oral intake), time to resolution, number of procedures needed for resolution, microbiology, length of stay, and neck morbidity. Results: A total of 13 patients were included (10 men). Median age was 52 years (range, 24-74 years). All patients underwent surgical drainage, repair, or attempted repair of perforation, hardware removal, and establishment of enteral access. Wounds were managed closed versus open (6 closed, 7 open). There were 2 early postoperative deaths due to acute respiratory distress syndrome and aspiration (open group), and 1 patient was lost to follow-up (closed group). Among the remaining 10 patients: resolution rate was 80% versus 100%, resolution in 30 days was 20% versus 100%, median number of procedures needed for resolution was 3 versus 1, and median hospital stay was 23 versus 14 days, for the closed and open groups, respectively. Conclusions: Esophageal perforation following anterior cervical spine surgery should be managed in a multidisciplinary fashion with surgical neck drainage, primary repair when feasible, hardware removal, and establishment of enteral access. We advocate open neck wound management to decrease the time-to-resolution, number of procedures, and length of stay.

Synthesis, molecular simulation studies, in vitro biological assessment of 2-substituted benzoxazole derivatives as promising antimicrobial agents.

The 2-substituted benzoxazole derivatives are known to exhibit a wide spectrum of biological potential. Two series of novel benzoxazole derivatives containing 2-phenyl and 2-N-phenyl groups were synthesized, by following the green chemistry approach. All the newly synthesized derivatives were screened against gram-positive bacteria (Streptococcus pyogenes, Staphylococcus aureus), gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli) and the fungus (Aspergillus clavatus and Candida albicans). Most of these compounds have demonstrated potent antibacterial activities, especially against E. coli at 25 µg/mL, along with moderate antifungal activity. Among these, two compounds, 21 and 18, showed interesting antibacterial profile. Molecular docking studies suggested that the antibacterial activity can be linked to the inhibition of DNA gyrase. Overall, the study proposes that these biologically potent compounds can be considered for developing the next generation antimicrobial agents.

A nationwide analysis of disparities in guideline-concordant care in American Indians and Alaska Natives with stage I non-small cell lung cancer.

Background: Several studies have shown racial disparities in lung cancer care in the United States in the Black and Hispanic populations but not many have included American Indian/Alaska Native (AI/AN) patients. We retrospectively evaluated the factors associated with receipt of guideline-concordant care in AI/AN and non-Hispanic White (NHW) patients with stage I non-small cell lung cancer (NSCLC) and describe the relationship between guideline-concordant care and survival outcomes in these populations. Methods: Using the National Cancer Database, we identified NHW and AI/AN patients diagnosed with stage I NSCLC between 2004 and 2017. We evaluated the utilization of anatomic resection among both NHW and AI/AN and described the variables associated with anatomic resection. We also evaluated 5-year overall survival (OS) by treatment and race. We used the chi-square test, multivariable analysis, and the Kaplan-Meier method for statistical analysis. Results: We identified 196,349 patients. Of these, 195,736 (99.69%) were NHW and 613 (0.31%) were AI/AN. Relative to NHW, AI/AN were more frequently diagnosed at a younger age (40% vs. 28% diagnosed at 18-64 years of age; P<0.001) and more commonly resided in rural areas (14% vs. 5%; P<0.001). In our multivariable analysis adjusting for all patient factors [age at diagnosis, sex, race, residence location, Charlson Comorbidity Index (CCI), tumor stage, lymph node status, and treatment facility], AI/AN patients were less likely to undergo anatomic resection than NHW patients [odds ratio (OR), 0.74; 95% confidence interval (CI): 0.62-0.89]. In our unadjusted survival analysis, AI/AN patients had lower 5-year OS than NHW (58% vs. 56%; P=0.04). When adjusted for surgery this difference was no longer significant. Conclusions: AI/AN patients with stage I NSCLC undergo anatomic resection less frequently than do NHW, with lower 5-year OS than NHW. However, this survival difference is mitigated when AI/AN undergo anatomic resection.

Surgical management of delayed-presentation diaphragm hernia: A single-institution experience.

Objectives: Delayed-presentation diaphragm hernias are uncommon, and surgical management varies widely across practices. We describe our surgical experience with delayed-presentation diaphragm hernias as a case series of 14 patients, 9 of whom underwent minimally invasive repair. Methods: We performed a retrospective chart review of our prospective database of all patients treated surgically for delayed-presentation diaphragm hernia at our institution from January 1, 2005, to April 30, 2021. We excluded patients with poststernotomy, post-left ventricular assist device, and previously diagnosed congenital hernias. We recorded patient demographics, etiology, laterality, chronicity, operative details, postoperative complications, and long-term results. Results: We performed surgical repair of delayed-presentation diaphragm hernia in 14 patients. Eleven patients (79%) were male, the median age was 61 (18-83) years, the median body mass index was 29.2 (14.5-33.7), and 8 (57%) hernias were left-sided. Etiology was trauma (n = 7, 50%), iatrogenic (n = 5, 36%), and unknown (n = 2, 14%). Median time to presentation in patients with traumatic and iatrogenic hernias was 7.5 years (6 weeks to 38 years). Nine patients (64%) underwent minimally invasive repair, and 5 patients (36%) underwent open repair. We used a synthetic patch in all but 2 patients (86%). Median length of stay was 5 (3-27) days. Two patients (14%) had major complications. There were no deaths. Twelve patients (86%) had follow-up imaging at a median follow-up of 17 months (1-192) with zero recurrences. Conclusions: Our experience suggests that a minimally invasive or an open approach to patients with a delayed-presentation diaphragm hernia is safe and effective. We recommend tailoring the surgical approach based on patient characteristics, anatomic considerations, and surgeons' experience.

Bacterial profile and antibiotic susceptibility pattern of uropathogens causing urinary tract infection in the eastern part of Northern India.

Urinary tract infection (UTI) is a common infectious disease that affects men and women. It is a significant health concern due to multidrug-resistant (MDR) organisms. Therefore, it is necessary to have a current understanding of the antibiotic susceptibility (AS) pattern of uropathogens to manage UTI effectively. Since the bacterial pathogen causing UTI and its AS vary with time and place, the prevailing AS pattern of the causative agents are essential for empirical antibiotic therapy. This study aims to determine the prevalence and AS of uropathogens isolated from UTI patients in the eastern part of Northern India. The study was carried out between November 2018 and December 2019. Clean catch midstream urine samples were collected and processed using standard guidelines for microbiological procedures. Positive microbiological cultures were found in 333 of the 427 patients, where 287 were gram-negative bacteria (GNB), and 46 were gram-positive bacteria (GPB). Females had a higher prevalence of UTI (60.7%) than males (39.3%) (p = 0.00024). The most susceptible age group in females was 18-50 years as compared to males, whereas at the age of 51-80 years and >80 years males were more susceptible than females (p = 0.053). The most prevalent pathogen identified were Escherichia coli (55.0%), followed by Proteus sp. (6.9%), Klebsiella pneumoniae (6.6%), Pseudomonas aeruginosa (6.3%), of which 96.0% were MDR bacteria. The susceptibility pattern of our study also revealed that amikacin, gentamycin and imipenem were the most effective drugs against GNB. In contrast, nitrofurantoin, vancomycin, and chloramphenicol were the most effective drugs against GPB. According tothe findings, MDR pathogens are very much prevalent. Since UTI is one of the most frequent bacterial diseases, proper management necessitates extensive investigation and implementation of antibiotic policy based on AS patterns for a particular region.

Nonsupercharged Retrosternal Roux-en-Y Esophagojejunostomy for Distal Esophageal Reconstruction.

BACKGROUND: Delayed distal esophageal reconstruction with nonsupercharged jejunum is an option when gastric conduit is not available. This study aimed to describe a single-center experience with distal esophageal reconstruction with retrosternal Roux-en-Y esophagojejunostomy (RYEJ) and compare perioperative outcomes with retrosternal gastric pull-up (GP). METHODS: An Institutional Review Board-exempt retrospective chart review was conducted of patients who underwent esophagostomy closure by the retrosternal route at the University of Minnesota Medical Center (Minneapolis, MN) from January 2009 to July 2019. Patients with colonic conduits were excluded. The study compared patients with RYEJ with a contemporary cohort of patients who underwent GP. The anatomic criteria for RYEJ were the absence of a gastric conduit and an esophageal remnant that reached the sternomanubrial joint. Patient characteristics, anastomotic leak and stricture rate, postoperative complications, hospital length of stay, 30-day readmission, and 90-day mortality were recorded. Statistical analysis was performed using the Fisher exact test and the Wilcoxon rank-sum test with a significance level at P ≤.05. RESULTS: A total of 9 patients underwent RYEJ, and 10 patients had GP. Previous esophageal adenocarcinoma was more common in the RYEJ group (n = 5) compared with the GP group (n = 0) (P = .01). Patient demographics and comorbidities were comparable between the groups. No differences were found in all end points, including operating time, estimated blood loss, anastomotic leak or stricture rate, Clavien-Dindo class III to IV complications, hospital length of stay, or mortality. CONCLUSIONS: Retrosternal RYEJ without microvascular augmentation is a safe alternative for esophagostomy closure in patients with adequate esophageal length when the stomach is not available. The nonsupercharged jejunum can safely reach the level of the sternomanubrial joint.

Subxiphoid-subcostal versus transthoracic thoracoscopic thymectomy: A safe and feasible approach.

Objective: Subxiphoid-subcostal thoracoscopic thymectomy (ST) is an emerging alternative to transthoracic thoracoscopic thymectomy. Potential advantages of ST are the avoidance of intercostal incisions and visualization of both phrenic nerves in their entirety. We describe our experience with ST and compare our results to our previous experience with transthoracic thoracoscopic thymectomy. Methods: We conducted an institutional review board-exempt retrospective review of all patients who had a minimally invasive thymectomy from August 2008 to October 2021. We excluded patients with a previous sternotomy or radiological evidence of invasion into major vasculature. The ST approach involved 1 subxiphoid port for initial access, 2 subcostal ports on each side, and carbon dioxide insufflation. We used descriptive and comparative statistics on demographic, operative, and postoperative data. Results: We performed ST in 40 patients and transthoracic thoracoscopic thymectomy in 16 patients. The median age was higher in the ST group (58 years vs 34 years; P = .02). Operative data showed no significant differences in operative times, blood loss, or tumor characteristics. In the ST group, we had 2 emergency conversions for bleeding; 1 ministernotomy, and 1 sternotomy. Postoperative data showed that the ST group had fewer days with a chest tube (1 day vs 2.5 days; P = .02). There were no differences in median length of stay, tumor characteristics, final margins, major complication rate, and opioid requirements between the groups. There has been no incidence of diaphragmatic hernia and no phrenic nerve injuries or mortality in either group. Conclusions: ST is safe and has similar outcomes compared with transthoracic thoracoscopic thymectomy.

Long-Term Results of Diaphragmatic Hernia Repair After Left Ventricular Assist Device Explantation.

BACKGROUND: Diaphragmatic hernias after explantation of a left ventricular assist device (LVAD) at the time of heart transplantation are uncommon, but they can cause morbidity. This study presents midterm to long-term results of diaphragmatic hernia repair in these patients. METHODS: A retrospective chart review was performed on a prospectively collected database of all patients who underwent sequential LVAD explantation and heart transplantation at the University of Minnesota (Minneapolis, MN) since 1995. All patients who had a diaphragmatic hernia were included in the study. Patients' demographics, perioperative morbidity, and long-term results were recorded. RESULTS: From January 1995 to June 2018, 712 LVADs were placed, and subsequently 293 hearts were transplanted. The incidence of diaphragmatic hernia after heart transplantation was 7.1% (n = 21), with a median time from transplantation to diagnosis of 23 months (interquartile range [IQR], 9 to 39 months). Four patients did not undergo operative repair, and 1 patient was excluded for insufficient data. Sixteen patients underwent diaphragmatic hernia repair (male, 13; female, 3). Thirteen patients underwent laparoscopic repair with mesh, and 3 patients had open repair. Two patients presented with strangulated hernias requiring laparotomy and bowel resection. Median follow-up time was 53 months (IQR, 12 to 141 months) for the entire cohort. One recurrence was noted (6.2%), in a patient with laparoscopic repair. CONCLUSIONS: Diaphragmatic hernia repair after sequential LVAD explantation and orthotopic heart transplantation is feasible and appears to be safe. When this hernia is diagnosed, patients should be referred for surgical evaluation.

A herpes oncolytic virus can be delivered via the vasculature to produce biologic changes in human colorectal cancer.

Genetically engineered herpes simplex viruses (HSVs) can selectively infect and replicate in cancer cells, and are candidates for use as oncolytic therapy. This long-term report of a phase I trial examines vascular administration of HSV as therapy for cancer. Twelve subjects with metastatic colorectal cancer within the liver failing first-line chemotherapy were treated in four cohorts with a single dose (3 x 10(6) to 1 x 10(8) particles) of NV1020, a multimutated, replication-competent HSV. After hepatic arterial administration, subjects were observed for 4 weeks before starting intra-arterial chemotherapy. All patients exhibited progression of disease before HSV injection. During observation, levels of the tumor marker carcinoembryonic antigen (CEA) decreased (median % drop = 24%; range 13-74%; P < 0.02). One of three individuals at the 10(8) level showed a 39% radiologic decrease in tumor size by cross-section and 75% by volume. HSV infection was documented from liver tumor biopsies. After beginning regional chemotherapy, all patients demonstrated a further decrease in CEA (median 96%; range 50-98%; P < 0.008) and a radiologic partial response. Median survival for this group was 25 months. During follow-up, no signs of virus reactivation were found. Multimutated HSV can be delivered safely into the human bloodstream to produce selective infection of tumor tissues and biologic effects.

Dysphagia prevalence and associated survival differences in older patients with lung cancer: A SEER-Medicare population-based study.

INTRODUCTION: The impact of dysphagia in persons with lung cancer is unknown. The objective of this study is to measure the prevalence and survival differences associated with dysphagia in older adults with lung cancer. MATERIALS AND METHODS: Linked SEER cancer registries - Medicare data, 1991-2009 was utilized to identify 201,674 persons with lung cancer. Most were male (53%), had regional or distant disease (74%), and were aged <80 years (82%). The pre-existing prevalence of dysphagia was identified using claims codes before the lung cancer diagnosis. Survival was analyzed using Kaplan Meier curves and Cox proportional hazard models. RESULTS: 8517 (4%) had dysphagia prior to their lung cancer diagnoses. Younger age, worse disease stage, more comorbidities, and hospital rurality were associated with higher likelihood of dysphagia. Patients with dysphagia had worse survival (median survival 8 months [95%CI 7,9]) than those without dysphagia (median survival 12 months [95%CI 11,13]). After adjusting for sociodemographic, clinical, and disease characteristics, dysphagia was still associated with worse survival (Hazard ratio of death 1.34, [95%CI 1.28-1.35], p ≤ .0001). DISCUSSION AND CONCLUSIONS: This is the first Medicare claims-based study of older adults with lung cancer and dysphagia. Pre-existing dysphagia occurred in approximately 1 in 25 patients with lung cancer and was associated with worse survival. Determining the best methods to evaluate and treat dysphagia in patients with lung cancer is an important avenue for future studies.

Synthesis of Some New Hydroxytriazenes and their Antimicrobial and Anti-inflammatory Activities.

BACKGROUND: Hydroxytriazenes and their derivatives have been studied for the biological and pharmacological applications in the past few years. These compounds possess antibacterial, antifungal, anti-inflammatory, analgesic and wound healing activities. In this study, we report the synthesis of ten hydroxytriazenes in two series derived from disubstituted aniline and studied for antimicrobial and anti-inflammatory activities. METHODS: For this purpose, 2-methyl-5-chloroaniline and 2-trifluoromethyl-5-chloroaniline were used to synthesize compounds A1-5 and B1-5 series, respectively. All compounds were synthesized by the reported method which involves three steps of the method (i) Reduction, (ii) Diazotization, (iii) Coupling. All synthesized compounds were characterized by various techniques CHN elemental analysis, FTIR, 1H NMR, and MASS spectral analysis. The antibacterial activities of the compounds were screened against S. aureus, S. pyogenes, E. coli, P. aeruginosa, and antifungal activities were against C. albicans, A. clavatus by the zone of inhibition method. In addition, anti-inflammatory activity was also evaluated by carrageenan-induced paw edema method and results were reported as % inhibition. RESULTS: All the synthesized compounds were obtained in pure form and their spectral data are in good agreement with their structure. The synthesized compounds have shown good antimicrobial activity and zone of inhibition was ranging 21 to 24 mm. Further antiinflammatory effect of the compounds was 96.58 to 98.71 % inhibition. CONCLUSION: The results of the present study indicate that chloro and trifluoromethyl substitution at hydroxytriazenes skeleton could improve anti-inflammatory and antimicrobial activities.

Synthesis, antidiabetic, antioxidant and anti-inflammatory activities of novel hydroxytriazenes based on sulpha drugs.

The present study is aimed to investigate the anti-inflammatory, antioxidant and antidiabetic activities of three series of hydroxytriazenes based on sulfa drugs viz; Sulphathiazole (ST), Sulfisoxazole (SF) and Sulphamethoxazole (SM). Antidiabetic activities of the synthesized hydroxytriazenes were investigated by α-glucosidase and α-amylase inhibition method and IC50 values were recorded. The compounds presented significant α-glucosidase and α-amylase inhibition effect with IC50 values ranging from 122 to 341 µg/mL. Anti-inflammatory activity was also investigated by carrageenan-induced paw edema (CPE) method, where % inhibition was up to 89% after 4 h of treatment and antioxidant properties of the similar compounds were assessed by DPPH and ABTS radical scavenging assays. Antioxidant capacity of all the hydroxytriazenes detected by ABTS assay, was significantly higher as compared to DPPH assay. The hydroxytriazenes having highest antioxidant capacity presented IC50 values for compound ST-1 and ST-6 are 488 µg/mL for DPPH, 54.12 µg/mL for ABTS and 858.5 µg/mL for DPPH, 48.0 µg/mL for ABTS, respectively. These results suggested that ABTS assay may be more useful than DPPH assay for synthetic antioxidants. The findings from the molecular docking experiments may also expand the formation of new potent sulpha drugs based hydroxytriazenes targeting towards the subunit of C-terminal of human maltase-glucoamylase for the treatment of diabetes metabolic disorder. Overall, highlight the multifunctional role of hydroxytriazenes as antidiabetic, antioxidant and anti-inflammatory agents.

An unusual case of ulnar collateral ligament avulsion in association with carpometacarpal dislocation of thumb is described. Symptoms and deformity caused by dislocation can mask the presence of injuries such as damage to the ulnar collateral ligament of thumb. This may lead to long term disability. A high index of suspicion and good clinical examination allows correct diagnosis and management of these uncommon injuries leading to a good clinical outcome.

A Review on Cardiovascular Outcome Studies of Dipeptidyl Peptidase-4 Inhibitors.

The U.S. Food and Drug Administration issued a guidance for pharmaceutical industry defining preapproval and postapproval requirements for the demonstration of cardiovascular (CV) safety for all new medications developed for glycemic management in type 2 diabetes. However, results published from the studies of dipeptidyl peptidase-4 (DPP-4) inhibitors are conflicting with regard to different CV endpoints. Upcoming CV outcome studies perhaps will be able to provide additional insights related to diabetes management and help to provide the answers to some of these concerns. This article provides a brief overview regarding how various CV safety evidence of DPP-4 inhibitor evolved over time that highlights possible implication in clinical practice and translates them into effective diabetes management.

Acute Trans-Diaphragmatic Herniation of the Caudate Lobe of the Liver.

Diaphragmatic liver herniation is often associated with thoracoabdominal trauma. Spontaneous diaphragmatic rupture is a thoracoabdominal emergency and requires a high index of suspicion combined with high-resolution imaging studies for establishing an accurate and timely diagnosis. We present a case report of a patient who was admitted to the emergency department with severe substernal chest pain and shortness of breath who was diagnosed with spontaneous diaphragmatic rupture and caudate liver herniation. The caudate lobe was incarcerated, contributing to the patient's symptoms. A celiotomy was performed and the defect was repaired primarily.
