Tofacitinib in Acute Severe Ulcerative Colitis (TACOS): A Randomized Controlled Trial.

INTRODUCTION: Intravenous corticosteroids are the mainstay of treatment of patients hospitalized with acute severe ulcerative colitis (ASUC). However, 30%-40% of the patients are refractory to corticosteroids. We investigated whether addition of tofacitinib to corticosteroids improved the treatment responsiveness in patients with ASUC. METHODS: This single-center, double-blind, placebo-controlled trial randomized adult patients with ASUC (defined by the Truelove Witts severity criteria) to receive either tofacitinib (10 mg thrice daily) or a matching placebo for 7 days while continuing intravenous corticosteroids (hydrocortisone 100 mg every 6 hours). The primary end point was response to treatment (decline in the Lichtiger index by >3 points and an absolute score <10 for 2 consecutive days without the need for rescue therapy) by day 7. The key secondary outcome was the cumulative probability of requiring initiation of infliximab or undergoing colectomy within 90 days following randomization. All analyses were performed in the intention-to-treat population. RESULTS: A total of 104 patients were randomly assigned to a treatment group (53 to tofacitinib and 51 to placebo). At day 7, response to treatment was achieved in 44/53 (83.01%) patients receiving tofacitinib vs 30/51 (58.82%) patients receiving placebo (odds ratio 3.42, 95% confidence interval 1.37-8.48, P = 0.007). The need for rescue therapy by day 7 was lower in the tofacitinib arm (odds ratio 0.27, 95% confidence interval 0.09-0.78, P = 0.01). The cumulative probability of need for rescue therapy at day 90 was 0.13 in patients who received tofacitinib vs 0.38 in patients receiving placebo (log-rank P = 0.003). Most of the treatment-related adverse effects were mild. One patient, receiving tofacitinib, developed dural venous sinus thrombosis. DISCUSSION: In patients with ASUC, combination of tofacitinib and corticosteroids improved treatment responsiveness and decreased the need for rescue therapy.

Facile Layer Diffusion Technique for Synthesis of Terbium-Based Metal Organic Framework for Fluorometric Sensing of Hydroquinone.

A photoluminescent terbium (III)-based Metal Organic Framework (MOF) was synthesized at room temperature by layer diffusion method utilizing mixed carboxylate linkers (4,4'-oxybis(benzoic acid) and benzene-1,3,5 tricarboxylic acid). Synthesized MOF has crystalline nature and rod-shaped morphology and is thermally stable up to 455 °C. The fluorescence emission spectra and theoretical results revealed that carboxylate linkers functioned as sensitizers for Tb(III) photoluminescence which resulted in four distinct emission peaks at 495, 547, 584, and 621 nm corresponding to the transitions 5D4 → 7F6, 5D4 → 7F5, 5D4 → 7F4, and 5D4 → 7F3. Using synthesized MOF as fluorescent probe, hydroquinone was detected in aqueous medium with a detection limit of 0.048 µM, remarkable recovery (95.6-101.1%), and relative standard deviation less than 2.25%. The quenching phenomenon may be ascribed to electron transfer from synthesized probe to oxidized hydroquinone via carboxylic groups on the surface of MOF, which is further supported by photo-induced electron transfer mechanism. This study introduces a cheaper, faster, and more accurate method for hydroquinone detection.

Effectiveness of CBT for reducing depression and anxiety in people with epilepsy: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Patients with epilepsy suffer from depression and anxiety that reduces quality of life. Cognitive behavioral therapy (CBT) among various non pharmacological treatment recommended for depression and anxiety. Since there are several articles reporting CBT treatment for depression in patients with epilepsy, we conduct a meta-analysis to evaluate the effectiveness of CBT for adult patients with epilepsy. METHODS: Four electronic databases PubMed, Scopus, Embase, and the Cochrane library searched for relevant studies. A detailed "RISK of bias" assessment has been done for included studies. Funnel plot was used for assessing publication Bias. R Software- RStudio 2022 was used to calculate standard mean difference (SMD). The study has been registered in PROSPERO (CRD42023447655). RESULTS: Eventually, a Total 13 studies involving 1222 patients met the eligibility criteria. There was decline in the Patient Health Questionnaire (PHQ) [SMD = -0.42, 95 % CI = -0.63 to -0.22], Neurologic Disorder Depression Inventory-Epilepsy (NDDI-E) [SMD = -0.53, 95 % CI = -0.75 to -0.31], Beck depression Inventory (BDI) [SMD = -0.69, 95 % CI = -1.08 to -0.30], Hospital Anxiety and Depression Scale-Depression (HADS-D) [SMD = -0.73 , 95 % CI = -0.94 to -0.52] and Hospital Anxiety and Depression Scale Anxiety subscale (HADS-A) [SMD = -0.66, 95 % CI = -0.87 to -0.45] score of the CBT group than that of the control group at post-intervention. The results showed that the improvement in QOLIE-31 score of the CBT group than that of the control group [SMD = 0.67, 95 % CI = 1.33] at post-intervention. CONCLUSION: The result of our study showed that Cognitive behavioral therapy is a superior therapy for treating anxiety and depression in epilepsy patients. CBT was effective in improving Quality of life in patients with epilepsy. However, the sample size varied across the trials, additional high-quality studies are needed in the future.

Effectiveness of Tofacitinib in Ulcerative Proctitis Compared to Left Sided Colitis and Pancolitis.

BACKGROUND: Ulcerative proctitis (UP), though associated with high symptom burden and poor quality of life, is excluded from most of the randomized controlled trials in UC, including the OCTAVE trials. We aimed to analyse the effectiveness of tofacitinib in UP, and compare it to that in left sided colitis (LSC) and pancolitis (PC). METHODS: This was a prospective cohort study. Patients with either steroid-dependent or refractory ulcerative colitis, who received tofacitinib, were divided into three groups based on the disease extent [UP, LSC and PC]. The primary outcome was comparison of proportion of patients in clinical remission in the three groups, at weeks 8, 16 and 48. Safety outcomes were reported using incidence rate per patient year of exposure. RESULTS: Clinical remission was achieved in 47%(15/32), 24%(23/94), and 43%(23/54) of patients at week 8, 56%(18/32), 37%(35/94), and 56%(30/54) of patients at week 16, and 59%(19/32), 38%(36/94), and 24%(13/54) of patients at week 48 in groups UP, LSC and PC, respectively. Corticosteroid-free clinical remission rates were significantly higher in patients in groups UP at week 48. Five (15%) patients with UP were primary non-responders to tofacitinib at week 16, while three (9%) patients had secondary loss of response at week 48. The probability of sustained clinical response was highest in patients with UP. Patients with UP had the lowest incidence of adverse effects. CONCLUSION: The effectiveness of tofacitinib in inducing and maintaining clinical remission is greater in patients with UP compared to LSC and PC.

Burden of Anxiety, Depression and Perceived Stress in Patients with Inflammatory Bowel Disease: A Cohort Study from North India.

BACKGROUND: Patients with Inflammatory bowel disease (IBD) are susceptible to psychiatric co-morbidities. We aimed to ascertain the burden of anxiety, depression, and perceived stress in patients with IBD from north India. METHODS: Consenting adult patients with an established diagnosis of IBD were enrolled. The enrolled patients filled the Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS) questionnaires. The patient and disease characteristics were analyzed to determine the correlations and predictors of psychiatric comorbidities. RESULTS: A total of 318 patients (255 UC, 63 CD; mean age 40.13 ± 12.06 years, 168 [52.8%] males; mean partial Mayo score 2.10 ± 2.35; and mean HBI 2.77 ± 2.13) were enrolled. The prevalence of anxiety, depression and moderate to high perceived stress was 14%, 12%, and 41%, respectively. Females had higher mean perceived stress, anxiety and depression scores compared to males. The partial Mayo score (PMS) correlated poorly with anxiety (ρ = 0.083, p = 0.187), depression (ρ = 0.123, p = 0.49) and perceived stress (ρ = 0.169; p = 0.007). The Harvey Bradshaw index (HBI) correlated fairly with anxiety (ρ = 0.336, p = 0.007) and poorly with depression (ρ = 0.287, p = 0.022) and perceived stress (ρ = 0.20; p = 0.117). Younger age (OR 0.93, 95% CI 0.90-0.97; p = 0.001) and hand-grip strength (OR 4.63, 95% CI 1.88-11.42; p = 0.001) predicted anxiety in patients with UC while rural area of residence (OR 4.75, 95% CI 1.03-21.98; p = 0.046) and HBI (OR 1.60, 95% CI 1.12-2.29; p = 0.009) were significant predictors of anxiety in patients with CD. CONCLUSION: Psychiatric comorbidities are common in patients with IBD, with higher prevalence in females. Young adults with UC and sarcopenia; and individuals with active CD living in rural areas are at an increased risk of anxiety.

Pituitary Dysfunction in Idiopathic Intracranial Hypertension: An Analysis of 80 Patients.

BACKGROUND: Empty sella is a commonly described imaging entity in patients with idiopathic intracranial hypertension (IIH). Though menstrual and hormonal disturbances have been associated with IIH, available literature lacks systematic analysis of pituitary hormonal disturbances in IIH. More so, the contribution of empty sella in causing pituitary hormonal abnormalities in patients of IIH has not been described. We carried out this study to systematically assess the pituitary hormonal abnormalities in patients with IIH and its relation to empty sella. METHODS: Eighty treatment naïve patients of IIH were recruited as per a predefined criterion. Magnetic resonance imaging (MRI) brain with detailed sella imaging and pituitary hormonal profile were done in all patients. RESULTS: Partial empty sella was seen in 55 patients (68.8%). Hormonal abnormalities were detected in 30 patients (37.5%), reduced cortisol levels in 20%, raised prolactin levels in 13.8%, low thyroid-stimulating hormone (TSH) levels in 3.8%, hypogonadism in 1.25%, and elevated levels of gonadotropins were found in 6.25% of participants. Hormonal disturbances were independent and were not associated with the presence of empty sella (p = 0.493). CONCLUSION: Hormonal abnormalities were observed in 37.5% patients with IIH. These abnormalities did not correlate with the presence or absence of empty sella. Pituitary dysfunction appears to be subclinical in IIH and responds to intracranial pressure reduction, not requiring specific hormonal therapies.

In silico molecular modelling studies and antibiofilm efficacy of shikonin against Candida albicans: mechanistic insight.

In the recent past, the occurrence of fungal infections has increased drastically and candidiasis, caused prominently by Candida albicans, is foremost among them which has caused significant mortality and morbidity majorly in immune-compromised patients. Shikonin is a well-known natural naphthazarin derivative with promising antifungal efficacy, but it's mechanism of action is still unclear. Keeping this in view, present work was designed to get a mechanistic insight of anti-candida efficacy of shikonin via in vitro experiments and in situ molecular modelling studies. The current exploratory study is based on research that uses both qualitative and quantitative techniques, including minimum inhibitory concentration, minimum biofilm inhibitory concentration, time kill assay, cell cycle analysis and apoptotic assays, static biofilm formation assays, microscopic biofilm assessment assays, ergosterol content estimation and molecular docking/simulation studies. The study revealed a notable effect of shikonin against Candida albicans, including retardation of biofilms. Shikonin, with its increasing concentration leads to candidal cell apoptosis and necrosis establishing its dose-dependent effect. Additionally, it exhibited fungicidal activity via a mechanism of action likely related to ergosterol complexation which was further corroborated by molecular docking and simulation studies.

Apart from that, relapsing of cases and resistance among available anticancer drugs along with associated side effects making the situation even worse. Therefore, it is a global emergency to develop potent and safer antibreast cancer agents. Isatin is most versatile and flying one nucleus which is an integral competent and various anticancer agent in clinical practice and widely used by various research groups around the globe for development of novel, potent, and safer antibreast cancer agents. This review will shed light on the structural insights and antiproliferative potential of various isatin-based derivatives developed for targeting breast cancer in last three decades that will help researchers in design and development of novel, potent, and safer isatin-based antibreast cancer agents.

Australian native fruits and vegetables: Chemical composition, nutritional profile, bioactivity and potential valorization by industries.

Australian native plants have adapted themselves to harsh climatic conditions enabling them to produce unique and high levels of secondary metabolites. Native fruits and vegetables have been an integral part of the Indigenous Australian diet and Bush medicine for centuries. They have recently gained popularity owing to their rich dietary fiber, minerals, polyphenolic and antioxidant contents. This review presents a comprehensive summary and critical assessment of the studies performed in the last few decades to understand the phytochemical and nutritional profiles and therapeutic properties of Australian native fruits and vegetables. Furthermore, the potential of these fruits and vegetables as functional food ingredients and in the prevention and treatment of different diseases is discussed. Research on the nutritional and phytochemical profiles and therapeutic activity of Australian vegetables is limited with most studies focused on native fruits. These fruits have demonstrated promising antioxidant, anticancer, anti-inflammatory and antimicrobial activities mostly in in vitro models. More research to a) identify novel bioactive compounds, b) define optimal post-harvest and extraction methods, and c) understand molecular mechanisms of pharmacological activity through preclinical and clinical studies is prudent for the prospective and wider use of Australian native fruits and vegetables by the food, pharmaceutical, and nutraceutical industries.

Antimicrobial and antibiofilm effects of shikonin with tea tree oil nanoemulsion against Candida albicans and Staphylococcus aureus.

The current work aims to develop a shikonin and tea tree oil loaded nanoemulsion system stabilized by a mixture of GRAS grade surfactants (Tween 20 and monoolein) and a cosurfactant (Transcutol P). This system was designed to address the poor aqueous solubility and photostability issues of shikonin. The authenticity of shikonin employed in this study was confirmed using nuclear magnetic resonance (NMR) spectroscopy. The optimized nanoemulsion exhibited highly favorable characteristics in terms of zeta potential (-23.8 mV), polydispersity index (0.216) and particle size (22.97 nm). These findings were corroborated by transmission electron microscopy (TEM) micrographs which confirmed the spherical and uniform nature of the nanoemulsion globules. Moreover, attenuated total reflectance (ATR) and X-ray diffraction analysis (XRD) analysis affirmed improved chemical stability and amorphization, respectively. Photodegradation studies were performed by exposing pure shikonin and the developed nanoemulsion to ultraviolet light for 1 h using a UV lamp, followed by high performance liquid chromatography (HPLC) analysis. The results confirmed that the developed nanoemulsion system imparts photoprotection to pure shikonin in the encapsulated system. Furthermore, the research investigated the effect of the nanoemulsion on biofilms formed by Candida albicans and methicillin resistant Staphylococcus aureus (MRSA). Scanning electron microscopy, florescence microscopy and phase contrast microscopy unveiled a remarkable reduction in biofilm area, accompanied by disruptions in the cell wall and abnormalities on the cell surface of the tested microorganisms. In conclusion, the nanoencapsulation of shikonin with tea tree oil as the lipid phase showcased significantly enhanced antimicrobial and antibiofilm potential compared to pure shikonin against resistant strains of Candida albicans and Staphylococcus aureus.

1,2,3-Triazole Derivatives as an Emerging Scaffold for Antifungal Drug Development against Candida albicans: A Comprehensive Review.

Candida infections are most prominent among fungal infections majorly target immunocompromised and hospitalized patients and cause significant morbidity and mortality. Candida albicans is the notorious and most prevalent among all pathogenic Candida strains. Its emerging resistance toward available antifungal agents making it hard to tackle and emerging as global healthcare emergency. Simultaneously, 1,2,3-triazole nucleus is a privileged scaffold that is gaining importance in antifungal drug development due to being a prominent bioactive linker and isostere of triazole based antifungal class core 1,2,4-triazole. Numerous reports have been updated in scientific literature in last few decades related to utilization of 1,2,3-triazole nucleus in antifungal drug development against Candida albicans. Present review will shed light on various preclinical studies focused on development of 1,2,3-triazole derivatives targeting Candida albicans along with brief highlight on clinical trials and newly approved drugs. Structure-activity relationship has been precisely discussed for each architect along with future perspective that will help medicinal chemists in design and development of potent antifungal agents for tackling infections derived from Candida albicans.

Design, synthesis, and biological evaluation of isatin-indole-3-carboxaldehyde hybrids as a new class of xanthine oxidase inhibitors.

A novel series of triazole-linked isatin-indole-3-carboxaldehyde hybrids based on the febuxostat skeleton and its binding site interactions were rationally designed and synthesized as potential xanthine oxidase inhibitors. Among the synthesized hybrids, A19 showed the most potent xanthine oxidase inhibition (IC50 = 0.37 µM) with the mixed-type inhibitory scenario. Structure-activity relationship studies revealed that methoxy (OCH3 ) substitution on position 5 of the isatin nucleus and a two-carbon distance between isatin and the triazole moiety is most tolerable for the inhibitory potential. Various binding interactions of A19 with the binding site of xanthine oxidase are also streamlined by molecular docking studies, which showcase the favorable binding pattern for xanthine oxidase inhibition by the hybrid. Furthermore, molecular dynamic studies were performed that suggest the stability of the enzyme-hybrid complex. Overall, the study suggests that hybrid A19 can act as an effective hit lead for further development of potent xanthine oxidase inhibitors.

Relationship between spirituality and depression among patients with malignant cancer at a selected tertiary care Institute - A study from North India.

Purpose: Depression is a major mental disorder and has drastic effects on people suffering from other terminal illnesses like cancer. Many patients struggling with chronic or fatal illnesses rely on spirituality to cope. Spirituality in Indian culture has always been a vital component in indigenous health systems.Objective: To determine the relationship between spirituality and depression among patients with cancer visiting a tertiary care institute of Uttarakhand State in northern India. Design: A descriptive cross-sectional survey.Sample: A total of 103 cancer patients visiting inpatient and outpatient departments of a selected tertiary care institute of Uttarakhand state of northern India.

Findings: The mean score of depression among cancer patients was 9.12±6.537 (CI, 7.84-10.39). Patients with high spirituality have minimal or no depression. We found a statistically significant negative correlation between depression and spirituality (r=-0.209, p=0.05).Conclusions: Health care professionals can incorporate spirituality in caring for cancer patients to develop a positive outlook on living despite the illness. Implications for Psychosocial Providers Or Policy: Establishing a spiritual support program as an integral part of a multidisciplinary approach can better cancer treatment in the Indian setting.

The Genetics of Ethambutol-Induced Optic Neuropathy: A Narrative Review.

Tuberculosis (TB) is a global health problem with the major brunt of disease occurring in developing countries. The cornerstone of treatment of TB is anti-tubercular therapy (ATT), which includes rifampicin, isoniazid, pyrazinamide and ethambutol. Because of emerging drug resistance, treatment failures, defaulters and increasing incidence of disseminated and extrapulmonary TB, the guidelines have been modified in some countries. Ethambutol is prescribed for longer times (in some cases >8 months) and hence the incidence of ethambutol-induced optic neuropathy (EtON) is expected to rise. The fundamental question which needs explanation is why only a small subset of patients on ethambutol are prone to develop loss of vision. This review focuses on available genetic studies which provide evidence that mitochondria are the likely substrates involved in the final pathway of reactive oxidative damage of the papillo-macular bundle. Genetic analysis of mitochondrial mutations encoding genes involved in oxidative phosphorylation pathways may help in isolating the subset of patients who are genetically susceptible. If the groups having high risk of developing EtON are recognised then prolonged duration of ethambutol treatment can be avoided in these susceptible individuals. A better understanding of the pathophysiology will also pave the way for the development of management strategies in this condition.

Diagnostic added value of interictal magnetic source imaging in presurgical evaluation of persons with epilepsy: A prospective blinded study.

BACKGROUND AND PURPOSE: In presurgical evaluation for epilepsy surgery, information is sourced from various imaging modalities to accurately localize the epileptogenic zone. Magnetoencephalography (MEG) is a newer noninvasive technique for localization. However, there is limited literature to evaluate if MEG provides additional advantage over the conventional imaging modalities in clinical decision making. The objective of this study was to assess the diagnostic added value of MEG in decision making before epilepsy surgery. METHOD: This was a prospective observational study. Patients underwent 3 h of recording in a MEG scanner, and the resulting localizations were compared with other complimentary investigations. Added value of MEG (considered separately from high-density electroencephalography) was defined as the frequency of cases in which (i) the information provided by magnetic source imaging (MSI) avoided implantation of intracranial electrodes and the patient was directly cleared for surgery, and (ii) MSI indicated additional substrates for implantation of intracranial electrodes. Postoperative seizure freedom was used as the diagnostic reference by which to measure the localizing accuracy of MSI. RESULTS: A total of 102 patients underwent epilepsy surgery. MEG provided nonredundant information, which contributed to deciding the course of surgery in 33% of the patients, and prevented intracranial recordings in 19%. A total of 76% of the patients underwent surgical resection in sublobes concordant with MSI localization, and the diagnostic odds ratio for good (Engel I) outcome in these patients was 2.3 (95% confidence interval 0.68, 7.86; p = 0.183) after long-term follow-up of 36 months. CONCLUSION: Magnetic source imaging yields additional useful information which can significantly alter as well as improve the surgical strategy for persons with epilepsy.

The development and efficacy of a mobile phone application to improve medication adherence for persons with epilepsy in limited resource settings: A preliminary study.

OBJECTIVE: Persons with epilepsy (PWE), especially those with limited education backgrounds from developing countries, are challenged by complicated medication regimens, debilitating seizures, and stigmatization in their daily life. Consequently, it is difficult for physicians to ensure medication adherence. This study validates a novel mobile application which was hypothesized to increase medication adherence and self-management skills in PWE. Created by medical professionals, the application included behavioral and educational components and was built to be easy-to-understand for those of socio-economically disadvantaged backgrounds. METHODS: This was a parallel, two-armed randomized controlled trial in which a total of 96 participants were enrolled from a Neurology Outpatient Department into a control standard care group and a mobile application group that used the smartphone application (app) in addition to the standard medical treatment. The app was intuitive and easy to understand for those coming from a socio-economically disadvantaged background. Medication adherence and self-efficacy were assessed with the Morisky Green and Levine Scale (MGLS) and the Epilepsy Self Efficacy Scale (ESES). Patients were reassessed 12 weeks later. Change in seizure frequency following administration of the application was a secondary outcome. RESULTS: In an intent-to-treat analysis, the mobile application interventional group showed over a 60% increase in the proportion of medication adherence (P < 0.0001). The mean self-efficacy score for the mobile application group was increased from 269.5 to 289.75 (P < 0.0001). The control group showed no statistically significant increases in either the proportion adherent or mean self-efficacy scores. SIGNIFICANCE: This study demonstrated the statistically significant performance of a mobile application in improving medication adherence and self-management skills in Indian persons with epilepsy.

Halides as versatile anions in asymmetric anion-binding organocatalysis.

This review intends to provide an overview on the role of halide anions in the development of the research area of asymmetric anion-binding organocatalysis. Key early elucidation studies with chloride as counter-anion confirmed this type of alternative activation, which was then exploited in several processes and contributed to the advance and consolidation of anion-binding catalysis as a field. Thus, the use of the halide in the catalyst-anion complex as both a mere counter-anion spectator or an active nucleophile has been depicted, along with the new trends toward additional noncovalent contacts within the HB-donor catalyst and supramolecular interactions to both the anion and the cationic reactive species.

Acceptability, tolerability, and safety of fecal microbiota transplantation in patients with active ulcerative colitis (AT&S Study).

BACKGROUND AND AIM: Fecal microbiota transplantation (FMT) targets gut microbiome dysbiosis and is an emerging therapy for ulcerative colitis (UC). Although initial results with FMT in patients with active UC are encouraging, data regarding its acceptability, tolerability, and safety are scant. METHODS: A retrospective analysis of patients with active UC (Mayo clinic score ≥ 4), who received multisession FMT (at weeks 0, 2, 6, 10, 14, 18, and 22) via colonoscopy between June 2016 and June 2018, was performed. Patient acceptability, tolerability, and immediate and long-term safety of the therapy were assessed. RESULTS: Of the 129 patients with active UC who were offered FMT, 101 patients consented, giving acceptability of 78.3%. Fecal slurry retention time improved with each session (3.27 ± 1.06 h for the first session vs 5.12 ± 0.5 h for the seventh session). Abdominal discomfort, flatulence, abdominal distension, borborygmi, and low-grade fever (30.8%, 15.9%, 9.8%, 7.9%, and 7.6%, respectively) were the most common post-procedural short-term adverse events. Long-term adverse events included new-onset urticaria (n = 2, 4.3%), arthritis/arthralgia (n = 3, 6.5%), depression (n = 1, 2.2%), partial sensorineural hearing loss (n = 1, 2.2%), and allergic bronchitis (n = 1, 2.2%). Thirteen (12.9%) patients dropped out because of adverse events. CONCLUSION: Fecal microbiota transplantation appears to be a safe and well-tolerated procedure, with good acceptability in patients with active UC.

Pre-harvest application of hexanal formulations for improving post-harvest life and quality of mango (Mangifera indica L.) cv. Dashehari.

The highly perishable nature of the mango fruit which leads to quick deterioration in quality is the major limiting factor for mango growers of north India. Studies were, therefore, planned to determine the role of 'enhanced freshness formulation' (EFF) having hexanal as the main component in extending the storage life and quality of mango fruits of cultivar Dashehari. Aqueous formulations of hexanal are known to retard the activity of phospholipase-D thereby increasing the shelf-life and quality of stored fruits. Mango trees were given pre-harvest sprays of hexanal @800 µM, 1200 µM, 1600 µM and 2000 µM at 30 and 15 days before harvesting of the fruit. After harvest at physiologically mature stage, fruits were stored in walk-in-cool chambers at a temperature of 12 ± 2 °C and 85-90% relative humidity. These fruits were analysed for different physiological and biochemical parameters at weekly intervals till the stipulated storage period of 35 days. The results of the research revealed that the hexanal treatments widened the storage period of fruits while maintaining their freshness in comparison to the untreated mango fruits. Hexanal formulation @1600 µM significantly reduced the decay incidence, pectin methyl esterase activity and respiratory rate of mango fruits. These fruits also exhibited increased firmness, total soluble solids, acidity and maintained acceptable palatability up to 28 days of storage. The lower doses of EFF did not showed significant effect in expanding the storage span of fruits beyond 21 days while the higher dose of hexanal @2000 µM did not showed a significant enhancement in quality and storage life of mango fruits in comparison to hexanal @1600 µM.

Therapeutic status of hydroxychloroquine in COVID-19: A review.

Hydroxychloroquine (HCQ), a 4-aminoquinoline, is used worldwide mainly for its role in management of malaria and rheumatoid arthritis. In the present pandemic of coronavirus disease (COVID)-2019, the drug is being repurposed, based on its in vitro evidence of efficacy against coronavirus. There has been a lot of information, for and against the drug, and this review is an effort to bring forth the evidence and current understanding regarding role of HCQ in COVID-19. Clinical studies, case reports, and in vitro studies have generated conflicting results. There are concerns for use of HCQ because of the variable results and the known adverse effects like QT prolongation and hypoglycemia. In the current scenario, recommendations from Indian Council of Medical Research for use of HCQ in the prophylaxis of COVID-19 are being followed.
