Mapping ultra-processed foods (UPFs) in India: a formative research study.

BACKGROUND: Increased consumption of ultra-processed foods (UPFs) which have additives such as artificial colours, flavours and are usually high in salt, sugar, fats and specific preservatives, are associated with diet-related non-communicable diseases (NCDs). In India, there are no standard criteria for identifying UPFs using a classification system based on extent and purpose of industrial processing. Scientific literature on dietary intake of foods among Indian consumers classifies foods as unhealthy based on presence of excessive amounts of specific nutrients which makes it difficult to distinguish UPFs from other commercially available processed foods. METHODS: A literature review followed by an online grocery retailer scan for food label reading was conducted to map the types of UPFs in Indian food market and scrutinize their ingredient list for the presence of ultra-processed ingredients. All UPFs identified were randomly listed and then grouped into categories, followed by saliency analysis to understand preferred UPFs by consumers. Indian UPF categories were then finalized to inform a UPF screener. RESULTS: A lack of application of a uniform definition for UPFs in India was observed; hence descriptors such as junk-foods, fast-foods, ready-to-eat foods, instant-foods, processed-foods, packaged-foods, high-fat-sugar-and-salt foods were used for denoting UPFs. After initial scanning of such foods reported in literature based on standard definition of UPFs, an online grocery retailer scan of food labels for 375 brands (atleast 3 brands for each food item) confirmed 81 food items as UPFs. A range of packaged traditional recipes were also found to have UPF ingredients. Twenty three categories of UPFs were then developed and subjected to saliency analysis. Breads, chips and sugar-sweetened beverages (e.g. sodas and cold-drinks) were the most preferred UPFs while frozen ready-to-eat/cook foods (e.g. chicken nuggets and frozen kebabs) were least preferred. CONCLUSION: India needs to systematically apply a food classification system and define Indian food categories based on the level of industrial processing. Mapping of UPFs is the first step towards development of a quick screener that would generate UPF consumption data to inform clear policy guidelines and regulations around UPFs and address their impact on NCDs.

Celecoxib-induced acute generalized exanthematous pustulosis: uncommon and under-recognized side effect.

Celecoxib, a selective COX-2 inhibitor, and non-selective anti-inflammatory drug, is commonly prescribed as the first-line analgesic for osteoarthritis, rheumatoid arthritis, and certain acute pain cases. It is mainly preferred for its lower risk of gastrointestinal adverse effects. However, it also carries risks, including renal and liver toxicity, anaphylaxis, and Stevens-Johnson syndrome. A rare but severe cutaneous adverse reaction associated with celecoxib is Acute Generalized Exanthematous Pustulosis (AGEP), characterized by extensive nonfollicular sterile pustules on an erythematous background, fever, and neutrophilic leukocytosis. AGEP is a rare condition with an incidence rate of 1-5 cases per million per year in the general population. It is primarily triggered by drugs, with antibiotics accounting for over 90 % of cases. Here, we present the case of a 44-year-old female who presented with a sudden, rapidly progressive, painful, pruritic rash all over her body with associated leukocytosis. A skin biopsy confirmed the presence of a pustular rash. The patient reported taking Celebrex (celecoxib) for worsening arthritis two weeks prior to symptom onset. The patient was diagnosed with Celecoxib-induced AGEP based on clinical and histopathological features. Treatment involved steroid therapy and discontinuation of NSAIDs (non-steroidal anti-inflammatory drugs). Encouragingly, the patient's rash improved within three days. Our case report aims to raise awareness of AGEP as a side effect of NSAIDs. Although AGEP is not typically serious, it can be fatal in elderly patients. Therefore, prompt identification and immediate cessation of the culprit drug is crucial.

5-Fluorouracil-Related Pneumatosis Intestinalis: A Case Report and Review of the Literature.

Pneumatosis intestinalis (PI) refers to the presence of air within the bowel wall. It can be associated with many causes including chemotherapy. We report a case of a 70-year-old male with metastatic tongue squamous cell carcinoma (SCC), whose hospital course was complicated by diarrhea and the development of PI, which was attributed to 5-fluorouracil (5-FU) chemotherapy after a comprehensive diagnostic workup and reassuring physical examination. The patient was treated conservatively with antibiotics and a bowel rest. A repeat imaging done before discharge showed stable findings. The patient was discharged afterward without complications. We highlight the importance of recognizing 5-FU as a cause for PI among patients with reassuring physical examination and diagnostic workup. Furthermore, we highlight that it may still be successfully managed with conservative measures.

Economic Burden of Otitis Media Globally and an Overview of the Current Scenario to Alleviate the Disease Burden: A Systematic Review.

Introduction The prevalence of otitis media (OM) is substantial all over the world. Epidemiological data related to the economic burden of OM globally is minimal. The present systematic review was undertaken to estimate the economic burden of this disease in various parts of the world. Objectives An extensive literature search was done using PRISMA guidelines to identify relevant studies that estimated the economic burden of OM in monetary terms. The databases searched were PubMed Central, Ovid, and Embase. The cost estimation was done for one specific year and then compared considering the inflation rate. Data Synthesis The literature search led to the inclusion of 10 studies. The studies evaluated direct and indirect costs in monetary terms. Direct costs (health system and patient perspective) ranged from USD (United States Dollar) 122.64 (Netherlands) to USD 633.6 (USA) per episode of OM. Looking at only the patient perspective, the costs ranged from USD 19.32 (Oman) to USD 80.5 (Saudi Arabia). The total costs (direct and indirect) ranged from USD 232.7 to USD 977 (UK) per episode of OM. The economic burden per year was highest in the USA (USD 5 billion). The incidence of OM episodes was found more in children < 5 years old. Introduction of pneumococcal conjugate vaccines decreased the incidence in children and now the prevalence in adults is of concern. Conclusion The economic burden of OM is relatively high globally and addressing this public health burden is important. Approaches for the prevention, diagnosis, and treatment should be undertaken by the health system to alleviate this disease burden.

Preventive hepatology at AIIMS Rishikesh: Delivering comprehensive and integrated care for liver diseases in Northern state of India.

Globally, liver diseases accounts for 4% of all deaths. Annually, over 2 million deaths occur due to preventable causes of chronic liver diseases and liver cancer like fatty liver diseases (alcoholic or non alcoholic) and viral hepatitis B and C. The burden of chronic liver diseases are increasing, and the epidemiology and demographics of people affected by these diseases are changing. Policy changes, vaccination, screening, lifestyle changes and public health awareness is the key to curb down liver disaeses. To achieve the ultimate goal of reducing mortality and linkage to care for those who need specialized care for liver disease, it is vital to have dedicated preventive hepatology clinics in sync with existing liver or gastroenterology clinics at tertary care level.

Effect of Hydroxychloroquine and Azithromycin Combination Use in COVID-19 Patients - An Umbrella Review.

Background: Hydroxychloroquine and Azithromycin combination was used rampantly in management of COVID-19 patients in different countries. Present review was conducted to evaluate the efficacy of Hydroxychloroquine and Azithromycin combination compared to the control (standard care) and any adverse effect following this combination use in COVID-19 patients if any. Material and Methods: We included all the systematic review with or without meta-analysis reporting the effect of Hydroxychloroquine (HCQ) and Azithromycin (AZM) combination use in COVID-19 patient using three databases namely PubMed, medline, CINHAL, Web of Science from July 2020 till Jan 2022. Results: The systematic search strategy has identified 104 studies in total, after removal of duplicates only 4 systematic reviews were included in the qualitative synthesis. The various tools for assessing and reporting the data in the reviews were PRISMA, ROBINS-I, Robs2, AMSTAR, MASTER checklists. Mortality among the hydroxychloroquine with azithromycin combination group was significantly higher than among the Standard Care group. The duration of hospital stay in days was shorter in the Standard Care group in comparison with the hydroxychloroquine group or the hydroxychloroquine and azithromycin combination group. Of the 4 systematic reviews included, 3 had low risk of bias and one had unclear risk of bias using the ROBIS tool. Chloroquine or Hydroxychloroquine combination did not shorten the duration of hospital stay. Conclusion: Rampant use of Chloroquine or Hydroxychloroquine alone or with Azithromycin combination caused adverse effects like QT prolongation. Finally, there is no evidence to support use of either Hydroxychloroquine with or without Azithromycin, for the treatment of COVID-19.

Cost-effectiveness analysis of surgical masks, N95 masks compared to wearing no mask for the prevention of COVID-19 among health care workers: Evidence from the public health care setting in India.

BACKGROUND: Nonpharmacological interventions, such as personal protective equipment for example, surgical masks and respirators, and maintenance of hand hygiene along with COVID-19 vaccines have been recommended to reduce viral transmission in the community and health care settings. There is evidence from the literature that surgical and N95 masks may reduce the initial degree of exposure to the virus. A limited research that has studied the cost-effective analysis of surgical masks and N95 masks among health care workers in the prevention of COVID-19 in India. The objective of this study was to estimate the cost-effectiveness of N95 and surgical mask compared to wearing no mask in public hospital settings for preventing COVID-19 infection among Health care workers (HCWs) from the health care provider's perspective. METHODS: A deterministic baseline model, without any mask use, based on Eikenberry et al was used to form the foundation for parameter estimation and to estimate transmission rates among HCWs. Information on mask efficacy, including the overall filtering efficiency of a mask and clinical efficiency, in terms of either inward efficiency(ei) or outward efficiency(e0), was obtained from published literature. Hospitalized HCWs were assumed to be in one of the disease states i.e., mild, moderate, severe, or critical. A total of 10,000 HCWs was considered as representative of the size of a tertiary care institution HCW population. The utility values for the mild, moderate and severe model health states were sourced from the primary data collection on quality-of-life of HCWs COVID-19 survivors. The utility scores for mild, moderate, and severe COVID-19 conditions were 0.88, 0.738 and 0.58, respectively. The cost of treatment for mild sickness (6,500 INR per day), moderate sickness (10,000 INR per day), severe (require ICU facility without ventilation, 15,000 INR per day), and critical (require ICU facility with ventilation per day, 18,000 INR) per day as per government and private COVID-19 treatment costs and capping were considered. One way sensitivity analyses were performed to identify the model inputs which had the largest impact on model results. RESULTS: The use of N95 masks compared to using no mask is cost-saving of $1,454,632 (INR 0.106 billion) per 10,000 HCWs in a year. The use of N95 masks compared to using surgical masks is cost-saving of $63,919 (INR 0.005 billion) per 10,000 HCWs in a year. the use of surgical masks compared to using no mask is cost-saving of $1,390,713 (INR 0.102 billion) per 10,000 HCWs in a year. The uncertainty analysis showed that considering fixed transmission rate (1.7), adoption of mask efficiency as 20%, 50% and 80% reduces the cumulative relative mortality to 41%, 79% and 94% respectively. On considering ei = e0 (99%) for N95 and surgical mask with ei = e0 (90%) the cumulative relative mortality was reduced by 97% and the use of N95 masks compared to using surgical masks is cost-saving of $24,361 (INR 0.002 billion) per 10,000 HCWs in a year. DISCUSSION: Both considered interventions were dominant compared to no mask based on the model estimates. N95 masks were also dominant compared to surgical masks.

Additive effects of TPMT and NUDT15 on thiopurine toxicity in children with acute lymphoblastic leukemia across multiethnic populations.

BACKGROUND: Thiopurines such as mercaptopurine (MP) are widely used to treat acute lymphoblastic leukemia (ALL). Thiopurine-S-methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) inactivate thiopurines, and no-function variants are associated with drug-induced myelosuppression. Dose adjustment of MP is strongly recommended in patients with intermediate or complete loss of activity of TPMT and NUDT15. However, the extent of dosage reduction recommended for patients with intermediate activity in both enzymes is currently not clear. METHODS: MP dosages during maintenance were collected from 1768 patients with ALL in Singapore, Guatemala, India, and North America. Patients were genotyped for TPMT and NUDT15, and actionable variants defined by the Clinical Pharmacogenetics Implementation Consortium were used to classify patients as TPMT and NUDT15 normal metabolizers (TPMT/NUDT15 NM), TPMT or NUDT15 intermediate metabolizers (TPMT IM or NUDT15 IM), or TPMT and NUDT15 compound intermediate metabolizers (TPMT/NUDT15 IM/IM). In parallel, we evaluated MP toxicity, metabolism, and dose adjustment using a Tpmt/Nudt15 combined heterozygous mouse model (Tpmt+/-/Nudt15+/-). RESULTS: Twenty-two patients (1.2%) were TPMT/NUDT15 IM/IM in the cohort, with the majority self-reported as Hispanics (68.2%, 15/22). TPMT/NUDT15 IM/IM patients tolerated a median daily MP dose of 25.7 mg/m2 (interquartile range = 19.0-31.1 mg/m2), significantly lower than TPMT IM and NUDT15 IM dosage (P < .001). Similarly, Tpmt+/-/Nudt15+/- mice displayed excessive hematopoietic toxicity and accumulated more metabolite (DNA-TG) than wild-type or single heterozygous mice, which was effectively mitigated by a genotype-guided dose titration of MP. CONCLUSION: We recommend more substantial dose reductions to individualize MP therapy and mitigate toxicity in TPMT/NUDT15 IM/IM patients.

A Versatile Protocol for Efficient Transformation and Regeneration in Mega Indica Rice Cultivar MTU1010: Optimization through Hormonal Variables.

Rice is one of the apex food crops in terms of meeting the daily calorific and dietary requirement of the majority of the world population. However, rice productivity is severely limited by various biotic and abiotic attributes, causing a severe threat to global food security. In the use of functional genomics and genome editing for the generation of trait-enhanced genotypes, it is necessary to have an efficient genetic transformation and regeneration protocol. The recalcitrant nature and paucity of efficient and versatile genetic transformation and regeneration protocols for indica cultivars remains a constraint. In the present study, we have optimized a tissue culture method for MTU1010, a mega indica rice variety. We conducted a combinatorial analysis of different plant growth regulators on embryogenic callus induction efficiency, and it was observed that MSB5 medium supplemented with 2.5 mg/L 2-4D and 0.25 mg/L 6-BAP results in maximum embryogenic callus induction, i.e., 92%. The regeneration efficiency of a transformed callus can be enhanced by up to 50% with the supplementation of 1 mg/L kinetin alongside 2.5 mg/L BAP and 0.5 mg/L NAA in the shooting medium. Furthermore, our results unveiled that the pre-activation of Agrobacterium culture for 30 min with 150 µM acetosyringone significantly increased the transformation efficiency of calli. Additionally, descaling the salt concentration to half strength in resuspension and co-cultivation increased the efficiency of transformation up to 33%. Thus, the protocol developed in this study will be instrumental for the genome editing and genetic engineering of indica rice cultivars for functional genomics studies and crop improvement.

Expert group recommendation on inhaled mucoactive drugs in pediatric respiratory diseases: an Indian perspective.

Background: Currently, there are no guidelines or consensus statements about the usage of inhaled mucoactive drugs in pediatric respiratory disease conditions from an Indian perspective. Objective: To develop a practical consensus document to help pediatricians in clinical decision-making when choosing an appropriate mucoactive drug for the management of specific respiratory disease conditions. Methods: A committee of nine experts with significant experience in pediatric respiratory disease conditions and a microbiological expert constituted the panel. An electronic search of the PubMed/MEDLINE, Cochrane Library, Scopus, and Embase databases was undertaken to identify relevant articles. Various combinations of keywords such as inhaled, nebulized, mucoactive, mucolytic, mucokinetic, expectorants, mucoregulators, mucociliary clearance, respiratory disorders, pediatric, cystic fibrosis (CF), non-CF bronchiectasis, acute wheezing, asthma, primary ciliary dyskinesia (PCD), critically ill, mechanical ventilation, tracheomalacia, tracheobronchomalacia, esophageal atresia (EA), tracheoesophageal fistula (TEF), acute bronchiolitis, sputum induction, guideline, and management were used. Twelve questions were drafted for discussion. A roundtable meeting of experts was conducted to arrive at a consensus. The level of evidence and class of recommendation were weighed and graded. Conclusions: Inhaled mucoactive drugs (hypertonic saline, dry powder mannitol, and dornase alfa) can enhance mucociliary clearance in children with CF. Experts opined that hypertonic saline could be beneficial in non-CF bronchiectasis, acute bronchiolitis, and PCD. The current state of evidence is inadequate to support the use of inhaled mucoactive drugs in asthma, acute wheezing, tracheomalacia, tracheobronchomalacia, and EA with TEF.

A rapid and cost-effective method based on dispersive liquid-liquid microextraction coupled to injection port silylation-gas chromatography-mass spectrometry for determination of morphine in illicit opium.

A simple, rapid, cost-effective and environment friendly analytical method based on dispersive liquid-liquid microextraction (DLLME) coupled to injection port silylation (IPS)-gas chromatography-mass spectrometry is described for the determination of morphine in illicit opium samples. Raw opium was dispersed in ultrapure water and 5 mL of aqueous sample was subjected to DLLME by rapidly injecting a mixture of chloroform and acetone (extraction and disperser solvent, respectively) followed by ultrasonication for 1 min and subsequent centrifugation for 3 min at 5000 rpm. The sedimented phase thus obtained was reconstituted in acetonitrile and 1 µL along with 1 µL of N,O-Bis(trimethylsilyl)acetamide (BSA) was injected manually into GC-MS injection port at a temperature of 250°C. The derivatization reaction was completed instantaneously inside the heated GC-MS injection port without any side product. Various parameters associated with IPS and DLLME have been thoroughly optimized. Under the optimized conditions, the method has been found linear in the range of 5-50 µg/mL with a correlation coefficient (R 2) of 0.997. The limit of detection (LOD) and limit of quantification (LOQ) for morphine-diTMS were found to be 1.6 and 4.8 µg/mL. The method has been successfully applied for the quantitative analysis of morphine in illicit opium samples. In conclusion, the proposed method has completely eliminated the time consuming and laborious steps of LLE and in-vial silylation and can be routinely used for analysis of opium and other polar analytes in forensic science laboratories.

Butea frondosa as a gastro protective against induced gastric lesions

The study was undertaken to evaluate the potential of alcoholic extract of Butea frondosa Koen. ex Roxb against gastric lesions induced in rats using acetic acid plus pyloric ligation. The impact of alcoholic extract of Butea frondosa in doses of 100, 200 and 400 mg/kg as single dose schedules and 200 mg/kg for 7, 14, 21 and 28 days was determined. Parameters assessed were ulcer index, total acidity, acid volume, total protein and pH, non protein sulfhydryls and gastric wall mucus. Extract in dose of 400 mg/kg as a single schedule signifi cantly reduced ulcer severity, total protein and pH as against the control (p<0.05). Concurrent fi ndings were also observed with 200 mg/kg administered for 21 and 28 days. Treatment with 400 mg/kg of the extract as a single dose and 200 mg/kg for 28 days produced an elevation in the content on non protein sulfhydryls. Gastric wall mucus was enhanced with 200 mg/kg of the extract administered for 28 days with a value of 186±2.74 ìg Alcian blue/g wet weight compared with the control (p<0.05). A palpable decline in incidence of ulcers was observed with the extract which might be largely due to the presence of fl avonoids.
