The use of cyclooxygenase-2 inhibitors in depression: a narrative review of the state of evidence

Multiple lines of evidence suggest that inflammation contribute to the pathophysiology of depression. Various studies have found that patients with major depression have higher levels of pro-inflammatory cytokines like interleukin-1, interleukin-6, tumor necrosis factor-alpha and C-reactive protein. As a consequence of above findings this narrative literature review was done to look for the role of cyclooxygenase (COX)-2 inhibitors in the patients of depression. A web based search was done using the keywords like antidepressants, anti-inflammatory treatment, celecoxib, depression, neuro inflammation in well recognized databases like PubMed, Google scholar from the year 2006 to 2019 to come out with data that matches our inclusion criteria that have been pooled and critically analyzed. Although the exact mechanism remains to become elucidated the results suggest that COX-2 have beneficial role in treatment of depression and it may be used as an adjunct to the anti-depressant treatment as it may hasten the response to current treatment without any serious side effects

An experimental study to evaluate the role of aspirin and metformin in prevention of depression in rats

Background: Depression was seen to be associated with an increased level of inflammatory biomarkers along with the disturbance in the monoamine neurotransmitter system. Current therapies are mostly focussed on the neurotransmitters imbalance but due to increasing cases of treatment failure there is a need to shift our treatment focus to other potential therapies. This study aimed to evaluate the preventive role of aspirin and metformin in stress induced model of depression in wistar rats.Methods: Fifty four wistar rats were randomly divided into nine groups as normal control, experimental control, aspirin (30 mg/kg, 60 mg/kg), metformin (50 mg/kg, 100 mg/kg), two combination groups and imipramine (15 mg/kg). Depression model was created by the induction of chronic unpredictable mild stress (CUMS) for consecutive 28 days. Behavioural assessment was done by evaluating immobility time in forced swim test (FST) and sucrose preference ratio (SPR) in sucrose preference test. The data were analysed by analysis of variance (ANOVA) test using SPSS software. P0.05).Conclusions: Aspirin and metformin might have a potential role in the prevention of depression

Cost comparison of commonly used antidepressant drugs with drug price control order in India

Background: Price of a drug is an important factor for compliance to the treatment. So, to overcome the high prices of drugs, National Pharmaceutical Pricing Authority (NPPA) under government of India has issued Drug Price Control Order (DPCO) list containing commonly used drugs. Pharmaceutical companies can be punished if they keep their prices higher than the ceiling price mentioned in the DPCO. To find out the price variations of commonly used antidepressant drugs included in DPCO list of 29th April 2019.Methods: A list of all oral antidepressant drugs included in DPCO of 29th April 2019 and available in Indian market was procured from medguide India. Analysis of number of total brands following as well as not following DPCO ceiling price was done.Results: Author found 17 formulations of four antidepressant drugs included in DPCO. Total 556 brands found out of which 84.6% were following the DPCO and 15.4% of brands prices were higher than the ceiling price of DPCO.Conclusions: Though large number of companies are following the DPCO but still strict regulation is needed to further increase the compliance of guidelines

THE CONTROL OF BACTERIAL BLIGHT OF POMEGRANATE USING THE METHANOLIC EXTRACTS OF INDIAN BAEL AND LEUCAS ASPERA

Objectives: Blight disease occurring due to Xanthomonas axonopodis (pv. Punicae) has been creating a problem in pomegranate cultivation whose symptoms appear on leaves as well as on fruits and stem and thereby causing a detrimental effect on yield by reducing it to nearly 70–75%. In recent years, the disease has been controlled by nanoparticles (silver and copper). We are looking forward to an organic and more economic method for the control of blight disease of pomegranate which is farmer and consumer friendly. Methods: In the present work, the causative agent of disease was isolated from the infected pomegranate fruit which was collected from Bellary, Karnataka on nutrient agar media using streak plating method. Secondary metabolites were extracted from Leucas aspera and Indian bael using methanol as solvent from maceration and soxhlet extraction techniques for about six hours. These methods are considered as the traditional methods for extracting phenolic compounds along with the ultrasound assisted solvent extraction (UASE) method. Since UASE degrades the phenols and certain metabolites which act as nutrients we did not go for this technique. The Phytochemical screening of extracts was conducted to check the presence of secondary metabolites having antimicrobial activity. The methanolic extracts were characterised using thin layer chromatography (TLC) and Fourier transform infra-red (FTIR) spectroscopy. The antimicrobial activity for extracts of L. aspera and Indian bael were tested by agar disc diffusion method. Results: Clear Zone of Inhibition (ZOI) were observed for methanolic extracts of L. aspera (40 mg/ml and 100mg/ml) and Indian bael (160 mg/ml) which shows that the blight disease could be controlled. Conclusion: Indian bael methanolic extract (160 mg/ml) shows better control against growth of Xanthomonas species with higher ZOI values than L. aspera extracts (100 mg/ml and 40 mg/ml)

Comprehensive Analysis to Uncover Determinants of Patient Appointment Compliance in Ophthalmology at the Kresge Eye Institute

Introduction: Appointment compliance (AC) has a significant impact on physician-patient relationship and overall patient care. However, determinants of AC in Ophthalmology and its subspecialties remains elusive. Methods: We performed a five-year retrospective analysis across Kresge Eye Institute (KEI) and its affiliated Michigan locations. A total of 597,364 appointments across \u3e13 subspecialties were included. AC was the primary outcome of interest. Compliant (CO) and non-compliant (NC) groups were compared to the following variables: patient characteristics (gender, race, age, insurance), appointment rank (relative to patient history), scheduling location, month, and ophthalmic specialty, in regard to arrival and no-show. Results: Among all appointments, 59.77% were associated with a female patient and 79.16% of the total number of appointments were compliant. AC differed concerning specialty, with retina representing the highest compliance across all appointments. Among 200+ insurance providers, Medicare was most frequently used and represented the highest share of CO appointments. African Americans were the primary ethnicity served by KEI and had the highest number of NC appointments. Conclusion: Our study demonstrates the impact of patient demographics, appointment characteristics, and ophthalmic subspecialty on AC. A better understanding of these determinants could allow for an increased CO for Ophthalmology practices

Fe–TiO2_2 composite beads driven hybrid process of photocatalysis and photo-Fenton for the degradation of isoproturon

The concept of hybrid process of photo-Fenton and photocatalysis, particularly in the fixed mode, has been presented in this study for the degradation of the pesticide isoproturon with reduction at the time of treatment. For fixed-bed studies, spherical beads were prepared by combining definite proportions of clay, foundry sand, and fly ash, which were utilized as iron sources for titanium dioxide (TiO2) immobilization. The optimization of various parameters was performed by utilizing the Box–Behnken design model under response surface methodology. The process of degradation followed first-order kinetics under an optimized condition for the integrated degradation of isoproturon with a 700 mg${\cdot }$L-1 dose of H2O2, 42 spherical beads, and 190 mL of solution for a duration of 176 min at pH 3.7. Approximately 80.96% degradation of isoproturon was observed after inducing the optimized conditions. The integrated treatment was also carried out in a solar batch reactor under optimized conditions to expand its application to industries for treating bio-recalcitrant compounds. The mineralization of isoproturon was confirmed through the generation of nitrate, nitrite, and ammonical nitrogen with a definite chemical oxygen demand reduction. The recyclability of the catalyst was confirmed by recycling the spherical beads characterized by scanning electron microscopy–energy dispersive X-Ray analysis. For confirming the dual effect, that is, the presence of TiO2 along with Fe on the bead’s surface, various analyses including UV–diffuse reflectance spectroscopy, scanning electron microscopy–energy-dispersive spectroscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy were carried out. A tentative pathway for isoproturon removal was also predicted based on intermediate analysis through gas chromatography–mass spectroscopy

Phonophoresis in Physiotherapy: Mechanisms, Applications, and Emerging Trends for Enhanced Drug Delivery and Therapeutic Efficacy

Phonophoresis, a widely utilized treatment in physiotherapy, combines topically applied gel or cream-based medications with ultrasonic therapy to enhance percutaneous absorption of pharmacological agents. The procedure employs ultrasound frequencies of 0.7 to 1.1 MHz with intensities ranging from 0.0 to 3.0 Watts per cm². Indications for phonophoresis span various inflammatory, deformative, dermatological, and rheumatic/neurological conditions. Recent studies suggest its clinical efficacy in pain relief and improved function, especially in conditions like lateral epicondylitis and osteoarthritis. The mechanism of action involves both thermal and non-thermal effects, with cavitation playing a key role in enhancing transdermal transport. Phonophoresis offers a non-invasive alternative for drug delivery, bypassing hepatic metabolism and minimizing systemic side effects. Various medicinal gels, particularly diclofenac, are used for transdermal drug delivery through phonophoresis. Low frequency phonophoresis has gained attention for enhancing transdermal transport, especially for macromolecules. Its applications extend beyond physiotherapy to include ocular drug delivery, nail therapy, gene therapy, and sports sciences. Clinical studies demonstrate the effectiveness of phonophoresis in conditions like anterior knee pain, tuberculous lymphadenitis, acute low back pain, and latent myofascial trigger points. Dosage considerations emphasize optimizing thermal effects without causing tissue damage. Studies highlight the potential of phonophoresis in relieving pain and improving function, particularly in knee osteoarthritis. Additionally, phonophoresis with Phyllanthus amarus nanoparticle gel shows promise in reducing pain and enhancing functional capacity in symptomatic knee osteoarthritis. In summary, phonophoresis stands as a valuable modality in physiotherapy, showcasing diverse applications and demonstrating clinical efficacy in various musculoskeletal and inflammatory conditions. Further research is warranted to explore its full potential and optimize treatment protocols

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018 population-based measurement studies with 88.6 million participants

© The Author(s) 2018. Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups
