RESUMEN
This study aims to assess the climate change impact on the rainfall and temperature data of the Vadodara-Chhotaudepur district of India and to focus on the environmental challenges related to the rainfall and temperature in the present state of development, land use, industrialization, and urbanization. The study utilized nine trend analysis methods, namely linear regression (LR), Sen's robust slope estimator (SS), Mann-Kendall test (MK), Spearman's rank correlation (SRC), the trend-free pre-whitening (TFPW), variance correction approach by Hamed and Rao (1998) with MK test (MK-CF1), variance correction approach by Yue and Wang (2004) with MK test (MK-CF2), block bootstrap with MK test (BBS-MK), and graphical method as innovative trend analysis (ITA), applied on monthly, annual, and seasonal scales. Additionally, the study also employed four homogeneity analysis methods, including Pettitt's test, standard normal homogeneity test (SNHT), Buishand's test, and Von Neumann Ratio test (VNRTs). The IMD (Indian meteorological department) gridded long-term rainfall data from 1901 to 2019 and temperature data from 1951 to 2019 are used in the present study to assess the homogeneity and trends of the data series. Results showed a warming trend of maximum temperature (MaxT) and minimum temperature (MinT) at the monthly, annual, and seasonal time scale and significant (at 5%) warming trend in annual MinT in the entire study area. Annual rainfall showed negative trend in the study area with significant (at 5%) negative trend in eastern deforested area western industrial and area adjacent to thermal power station. The change point is detected in annual rainfall time series in eastern forest area in 1959 and western area in 1983, i.e., after development of the industries and commissioning of thermal power station in the western study area. The trend rate of MaxT and MinT has been recognized as 0.004 °C/year and 0.019 °C/year, respectively, for the data period of 1951 to 2019. The annual rainfall trend rate has been observed as -0.743 mm/year for the data range 1901 to 2019. All trend analysis methods revealed consistent results except MK-CF2 method, which portraits greater number of significant trends in trend analysis methods.

INTRODUCTION: Myiasis, tissue infestation by housefly larvae, is commonly found in malignant fungating wounds of cancer patients from climatic condition and lower socio-economic strata. AIM OF STUDY: It was aimed to study the effectiveness of systemic Ivermectin, Albendazole& Clindamycin (Triple Therapy) in reducing signs & symptoms associated with maggots in malignant head and neck wounds. METHOD: 25 adult, advanced head and neck cancer patients presenting with maggots either from wound, oral cavity or nostril, with ECOG score 3 or less were enrolled in this study. Symptoms were assessed using Edmonton Symptom Assessment Scale (ESAS) and wound by Wound Assessment Tool - Hospice, at baseline and then Days 1, 3, 5, and 7. All patients received 3 days course of oral Ivermectin 12 mg per day, Albendazole 400 mg twice per day and Clindamycin 300 mg three times per day for 5 days along with Terpentine oil dressing. All patients received oral Morphine as per their pain score. RESULTS: Mean age (yrs) and weight (Kg) were 42.15 ± 8.23 and 52.31 ± 5.18 respectively. 84% patients were male. Mean oral morphine dose was 100.38 mg. There was significant decrease in number of maggots from day 0 (77.28 ± 13.465) to day 1 (20.60 ± 7.263; 73.34% reduction) to day 3 (1.52 ± 2.104; 92.62% reduction). We found statistically significant improvement (P = <0.05) in scores of wound and all other related symptoms on days 1, 3, 5 & 7, except bleeding, edema, nausea, anxiety, appetite loss and feeling of wellbeing, which remained same on Day 1, but improved afterward. Side effects were self-limiting. CONCLUSION: Systemic treatment with Ivermectin, Albendazole and Clindamycin (Triple Therapy) enhances the removal of maggots, early recovery and relief from distress and associated symptoms.
RESUMEN
BACKGROUND: Head and neck cancer pain is intractable and difficult to manage. Many a times it is difficult to treat with oral opioids and adjuvants. AIM: This study aims to study the effects of transnasal sphenopalatine ganglion block (SPGB), administered using cotton swab/ear bud by patients' caretaker, at home, for pain management. STUDY DESIGN: This is a prospective, single-arm observational study conducted on 100 head and neck cancer patients, from January 2014 to December 2015. Patients and caretaker were given a demonstration of the procedure using sterile cotton swab/ear buds. They were advised to repeat the procedure when their visual analog score (VAS) was more than 5. They continued with the oral analgesics. They kept the records of pre- and post-procedure pain score (VAS), the frequency of repetition, ease of performance of procedure, and morphine requirement. A paired t-test (SPSS software) was used for statistical analysis. RESULTS: A significant reduction in pain was noted by a decrease in mean VAS from 8.57 ± 1.31 to 2.46 ± 1.23 (P < 0.0001), immediately on first administration. The mean duration of analgesia was 4.95 ± 3.43 days. Pre- and post-procedure mean morphine requirement were 128.2 ± 84.64 and 133.8 ± 81.93 (P > 0.05) mg per day, at the end of 2 months. Ease of performance was observed in 88 patients. CONCLUSION: The home-based application of SPGB is an easy, safe, and cost-effective method to manage cancer pain. It provides excellent immediate pain relief with a minimum side effect. It can be performed bilaterally, repeatedly and even with a feeding tube in place.
RESUMEN
BACKGROUND: An increase in worldwide HPV vaccination could be facilitated if fewer than three doses of vaccine are as effective as three doses. We originally aimed to compare the immunogenicity and frequency of persistent infection and cervical precancerous lesions caused by vaccine-targeted HPV after vaccination with two doses of quadrivalent vaccine on days 1 and 180 or later, with three doses on days 1, 60, and 180 or later, in a cluster-randomised trial. Suspension of the recruitment and vaccination due to events unrelated to our study meant that some enrolled girls could not be vaccinated and some vaccinated girls received fewer than the planned number of vaccinations by default. As a result, we re-analysed our data as an observational cohort study. METHODS: Our study was designed to be done in nine locations (188 clusters) in India. Participants were unmarried girls aged 10-18 years vaccinated in four cohorts: girls who received three doses of vaccine on days 1, 60, and 180 or later, two doses on days 1 and 180 or later, two doses on days 1 and 60 by default, and one dose by default. The primary outcomes were immunogenicity in terms of L1 genotype-specific binding antibody titres, neutralising antibody titres, and antibody avidity after vaccination for the vaccine-targeted HPV types 16, 18, 6, and 11 and incident and persistent infections with these HPVs. Analysis was per actual number of vaccine doses received. This study is registered with ISRCTN, number ISRCTN98283094; and with ClinicalTrials.gov, number NCT00923702. FINDINGS: Vaccination of eligible girls was initiated on Sept 1, 2009, and continued until April 8, 2010. Of 21â258 eligible girls identified at 188 clusters, 17â729 girls were recruited from 178 clusters before suspension. 4348 (25%) girls received three doses, 4979 (28%) received two doses on days 1 and 180 or later, 3452 (19%) received two doses at days 1 and 60, and 4950 (28%) received one dose. Immune response in the two-dose HPV vaccine group was non-inferior to the three-dose group (median fluorescence intensity ratio for HPV 16 1·12 [95% CI 1·02-1·23] and for HPV 18 1·04 [0·92-1·19]) at 7 months, but was inferior in the two-dose default (0·33 [0·29-0·38] for HPV 16 and 0·51 [0·43-0·59] for HPV 18) and one-dose default (0·09 [0·08-0·11] for HPV 16 and 0·12 [0·10-0·14] for HPV 18) groups at 18 months. The geometric mean avidity indices after fewer than three doses by design or default were non-inferior to those after three doses of vaccine. Fewer than three doses by design and default induced detectable concentrations of neutralising antibodies to all four vaccine-targeted HPV types, but at much lower concentration after one dose. Cervical samples from 2649 participants were tested and the frequency of incident HPV 16, 18, 6, and 11 infections was similar irrespective of the number of vaccine doses received. The testing of at least two samples from 838 participants showed that there was no persistent HPV 16 or 18 infections in any study group at a median follow-up of 4·7 years (IQR 4·2-5·1). INTERPRETATION: Despite the limitations imposed by the suspension of the HPV vaccination, our findings lend support to the WHO recommendation of two doses, at least 6 months apart, for routine vaccination of young girls. The short-term protection afforded by one dose of HPV vaccine against persistent infection with HPV 16, 18, 6, and 11 is similar to that afforded by two or three doses of vaccine and merits further assessment.

Angiogenesis plays an important role in tumor growth and prognostication. A key angiogenesis stimulator is vascular endothelial growth factor (VEGF). The present investigation aimed to study contribution of VEGFA isoforms in oral cancer progression. Reverse transcription polymerase chain reaction and ELISA were employed to analyze tissue VEGFA isoforms and serum VEGF levels, respectively, in 109 oral cancer cases and 50 controls. VEGF183 and VEGF165 were significantly downregulated in malignant tissues as compared to adjacent normal tissues. VEGF183 and VEGF189 were significantly associated with tumor differentiation and tumor size. VEGF165 was significantly higher in recurrent early stage tumors. Serum VEGF levels were significantly higher in cases as compared to the controls and were associated with tumor differentiation. Serum VEGF levels were significantly higher in patients with recurrent advanced stage tumors. Further, patients with high levels of VEGF165 and serum VEGF levels had the worst prognosis. VEGFA isoform status and serum VEGF levels play a significant role in the progression as well as prognosis of oral cancer.

Alterations in cell membrane glycosylation play important role in oral carcinogenesis. The present study evaluated salivary sialylation changes i.e. total sialic acid (TSA), sialidase activity, linkage specific (α2-3 and α2-6) sialoproteins and sialyl transferase (ST) activity in controls, patients with oral precancerous conditions (OPC) and oral cancer. Subjects enrolled included 100 controls, 50 patients with OPC, 100 oral cancer patients, and 30 post treatment follow-ups. TSA was estimated by spectrophotometric method, sialidase activity by spectrofluorometric assay and linkage specific biotinylated lectins (α2-3: sambucus nigra agglutinin and α2-6: maackia amurensis agglutinin) were used to detect α-2,3 and α-2,6 STs and sialoproteins by ELISA and dot blot respectively. An increasing trend of salivary TSA/TP ratio, sialidase activity, α2-3 sialoproteins, α-2,3 and α-2,6 ST activities was observed from controls to patients with OPC to oral cancer patients and levels were significantly elevated in oral cancer patients as compared to the controls. Sialidase activity exhibited significant association with metastasis and infiltration. Sialidase activity, TSA/TP ratio, α-2,3 and α-2,6 ST activities were found to be higher in patients with metastasis as compared to patients without metastasis. A progressive increase in TSA/TP ratio, sialidase activity, α2-3 and α2-6 sialoproteins was observed from controls to early to advanced stage of the disease. Sialidase activity, α2-3 and α2-6 sialoproteins and ST activities were found to be decreased in complete responders; while levels were elevated in non-responders. The results documented utility of salivary sialylation endpoints, a non invasive tool in monitoring of oral carcinogenesis.

The SARS-CoV-2 pandemic has caused unprecedented worldwide infections from persistent mutant variants with various degrees of infectivity and virulence. The elusiveness of a highly penetrant, worldwide vaccination strategy suggests that the complete eradication of SARS-CoV-2 is unlikely. Even with the advent of new antiviral agents, the disease burden worldwide continues to exceed current preventative and therapeutic strategies. Greater interest has been placed towards the development of affordable,broadly effective antiviral therapeutics. Here, we report that the small branched-chain fatty acid Valproic acid (VPA), approved for maintenance of seizure and bipolar disorder, has a novel anti- coronavirus activity that can be augmented with the addition of a long-chain, polyunsaturated omega-3 fatty acid, Docosahexaenoic acid (DHA). An EMR-based epidemiological study of patients tested for COVID-19 demonstrated a correlation exists between a reduced infection rate in patients treated withVPA of up to 25%, as well as a decreased risk of emergency room visits, hospitalization, ICU admission,and use of mechanical ventilation. In vitro studies have demonstrated that VPA modifies gene expression in MRC5 cells. Interestingly, VPA correlates with the inhibition of several SARS-CoV2 interacting genes and the greater inhibition of alpha-coronavirus HCoV-229E (a "common cold" virus) and SARS-CoV2. The VPA-DHA combination activates pre-existing intracellular antiviral mechanisms normally repressed by coronaviruses. Gene expression profiles demonstrate subtle differences in overall gene expression between VPA-treated and VPA-DHA-treated cells. HCoV-229E infection caused an intensely different response with a marked induction of multiple intracellular inflammatory genes. Changes in gene expression took at least 24 hours to manifest and most likely why prior drug screens failed to identify any antiviral VPA activity despite in silico predictions. This report demonstrates an interaction between HDAC inhibition and the potent activation of cellular antiviral responses. A foundation now exists for a low-cost, highly effective antiviral strategy when supplemented with DHA.

Objective: Palliative care services in India were established in the 1980s but there is no detailed up-to-date knowledge about the quality-of-service provision nationally. We aim to describe the current quality of palliative care provision in India, as measured against nationally adopted standards. Method: A digital survey adapted from the Indian Association of Palliative Care Standards Audit Tool was administered to 250 palliative care centres. Results: Two hundred and twenty-three (89%) palliative care centres participated - 26.4% were government-run, while the rest include non-governmental organisations, private hospitals, community-led initiatives and hospices. About 200 centres 'often' or 'always' fulfilled 16/21 desirable criteria; however, only 2/15 essential criteria were 'often' or 'always' fulfilled. Only 5.8% provide uninterrupted access to oral morphine. Significance of the results: Palliative care centres in India are falling short of meeting the essential quality standards, indicating the urgent need for new initiatives to drive national change.
RESUMEN
Melia dubia Cav. (Meliaceae), a fast-growing tropical tree finds use in plywood, pulp and high-value solid wood products. To increase its productivity, we must essentially capture genetic diversity and identify genotypes with superior wood properties. This study aimed to develop novel microsatellite markers from genomic data and validate the markers in M. dubia. Direct Seq-to-SSR approach was adopted and using an in-house Perl script, 426,390 SSR markers identified. For validation, selected 151 markers, of which 50 were genomic markers chosen randomly, and 101 were genic markers identified through BLAST2GO. Amplification was observed in all loci, and 81.4% generated high-quality, reproducible amplicons of the expected size. Out of 50 genomic markers, we used ten highly polymorphic markers to assess genetic diversity among 75 genotypes from three populations. One hundred fourteen alleles were recorded, with a moderate level of diversity and a positive fixation index. Twenty-nine genic markers representing 13 enzymes showing polymorphism for wood stiffness were selected for diversity assessment of 24 genotypes (12 genotypes each with high and low-stress wave velocity). The product size ranged from 87 to 279, covering the majority of the genome. Cluster and structure analysis segregated ~ 80% of the genotypes based on the trait. This is the first report of the development of genic markers from a genomic survey and has proved efficient in differentiating genotypes based on the trait. The markers developed in this study will be useful for genetic mapping, diversity estimation, marker-assisted selection for desired traits and breeding for wood traits in M. dubia.

RESUMEN
Earlier publication from the ongoing multi-centric study of the International Agency for Research on Cancer to evaluate less than three doses of the quadrivalent Human Papillomavirus (HPV) vaccine in India amongst unmarried girls demonstrated non-inferior total antibody titres, neutralizing antibody titres and antibody avidity in 2-dose recipients compared to 3-dose recipients at 15-18 years of age (Bhatla et al., 2018) [7]. The number of participants recruited at 15-18 years of age was 1515 and 1795 in the 3-dose and the 2-dose groups respectively. At a median follow-up of 7 years, incident HPV 16/18 infections were detected in 1.6% women receiving two doses and 0.8% women receiving three doses at 15-18 years. Frequency of incident infection was 7.0% in the age- and site-matched unvaccinated women (Nâ¯=â¯1484). No persistent infection from HPV 16 was observed in the 2- or 3-dose recipients and one (0.2%) persistent HPV 18 infection was documented, each in the 3-dose and 2-dose cohorts. Among the unvaccinated women, the frequency of HPV 16/18 persistent infection was 1.7%. The protection offered by two doses of quadrivalent HPV vaccine against incident and persistent infections in recipients at 15-18 years is comparable to that seen in 3-dose recipients at 15-18 years.

PURPOSE: More than 1 million new occurrences of cancer are diagnosed in India annually. Among patients with cancer, pain is a common and persistent symptom of the disease and its treatment. However, few studies to date have evaluated the prevalence of pain and the adequacy of pain management in Indian hospitals. This cross-sectional study aimed to assess the prevalence and sociodemographic patterns of cancer pain and pain management among a sample of inpatients and newly registered outpatients at four large regional cancer centers in India. METHODS: A sample of 1,600 patients with cancer who were current inpatients or newly registered outpatients were recruited and administered a questionnaire that was based on the Brief Pain Inventory. The survey tool included questions on demographics, medical history, and extent of clinical pain experienced. In addition, a pain management index score was created to link the severity of cancer pain with medication prescribed to treat it. RESULTS: A total of 88% of patients reported pain in the past 7 days, and approximately 60% reported that their worst pain was severe. Several demographic and medical characteristics of the study population predicted severe pain, including the following: lower educational level, outpatient status, and debt incurred as a result of illness. A total of 67% of patients were inadequately treated with analgesics. Inadequate pain management was associated with both treatment hospital and patient type, and patients who reported debt as a result of their illness were more likely to have inadequate pain management. CONCLUSION: A majority of Indian patients with cancer experience significant pain and receive inadequate pain management. Improvement of pain management for Indian patients with cancer is needed urgently.

Extending two-dose recommendations of HPV vaccine to girls between 15 and 18 years will reduce program cost and improve compliance. Immunogenicity and vaccine targeted HPV infection outcomes were compared between 1795 girls aged 15-18 years receiving two (1-180 days) and 1515 girls of same age receiving three (1-60-180 days) doses. Immunogenicity outcomes in 15-18 year old two-dose recipients were also compared with the 10-14 year old three-dose (Nâ¯=â¯2833) and two-dose (Nâ¯=â¯3184) recipients. The 15-18 year old two-dose recipients had non-inferior L1-binding antibody titres at seven months against vaccine-targeted HPV types compared to three-dose recipients at 15-18 years and three-dose recipients at 10-14 years of age. Neutralizing antibody titres at 18 months in 15-18 year old two-dose recipients were non-inferior to same age three-dose recipients for all except HPV 18. The titres were inferior to those in the 10-14 year old three-dose recipients for all targeted types. Frequency of incident infections from vaccine-targeted HPV types in the 15-18 year old two-dose recipients was similar to the three dose recipients. None of the girls receiving two or three doses had persistent infection from vaccine-targeted types. These findings support that two doses of HPV vaccine can be extended to girls aged 15-18 years.

Oral cancer has become a grave problem in many parts of the globe with two.thirds of the cases occurring in developing countries. Chronic inflammation plays a prominent role in the development of oral cancer. The rationale for molecular targeted prevention of oral cancer is promising. Therefore, there are continued improvements to our understanding of the molecular connections between inflammation and oral cancer. The inflammatory mediators including nuclear factor kappa B, vascular endothelial growth factor, inflammatory cytokines, prostaglandin pathways, p53, reactive oxygen and nitrogen species, and microRNAs are major key players in the pathogenesis of oral cancer. Currently, visual cytology.based techniques and biopsy are used to detect dysplasia and early stage of oral squamous cell carcinoma. These approaches are limited in their ability to judge the severities of oral lesions and are useful only after the appearance of visual changes. Thus, traditional cytological and biopsy assays combined with testing of inflammatory biomarkers would be beneficial for the efficient early detection of oral dysplastic lesions and early stages of oral squamous cell carcinoma.

Hair has psychological and sociological importance throughout the ages in framing the personality and general appearance of an individual. Significant progress is being made on discovering an effective and safe drug for hair growth. Angiogenesis, androgen antagonism, vasodilation, potassium channel opening and 5-alpha reductase inhibition are the major non-surgical therapeutic strategies of hair growth promotion. In spite of a flood of drugs claiming to be useful as hair growth promoters, more rational strategies, which can target the problem areas or stages of the hair growth cycle effectively, are still awaited. This article highlights the developments in hair rejuvenation strategies and reviews the potential of herbal drugs as safer and effective alternatives.

INTRODUCTION: Hair care, color and style play an important role in physical appearance and self-perception. Hair loss or alopecia is a common dermatological and affective disorder. Factors contributing to alopecia include genetic predisposition, hormonal factors, disease status, side effects of chemotherapeutic agents and stress. To keep pace with the demand for drugs for alopecia, attempts are being made to explore drugs with hair-growth-promotion activity. To explore and evaluate these, it is necessary to be familiar with the basics and the availability and suitability of techniques and experimental models of hair growth activity assessment. AREAS COVERED: Basic and advanced techniques and models for assessing hair growth activity. A variety of pharmacological models of hair growth are reviewed. This review will help in selecting a suitable, relevant, inexpensive, easy and reliable model for hair growth assessment. EXPERT OPINION: There is a need to identify the genes involved in hair follicle growth for the production of more effective animal models of the disorder. Standardization of pharmacological models will also be essential for better comparison and validation of results. Recently developed hair follicle organ culture models are a suitable, relevant and inexpensive alternative to traditional whole-animal pharmacological models and will, largely, replace whole-animal systems in the future.
