Abstract
Equisetum (Equisetaceae) has long been a focus of attention for botanists and palaeontologists because, given its extensive and well-documented fossil record, it is considered the oldest extant vascular plant and a key element in understanding vascular plant evolution. However, to date, no authentic fossil evidence of Equisetum has been found from the Indian Cenozoic. Here, we describe a new fossil species, namely, E. siwalikum sp. nov., recovered from the middle Siwalik (Late Miocene) sediments of Himachal Pradesh, western Himalaya. We identified fossil specimens based on morphological and epidermal characters. In addition, X-Ray diffraction (XRD) analysis was used to determine the mineral composition of compressed stems of Equisetum. The close affinity of our recovered Siwalik fossils to Equisetum is supported by the presence of both macromorphological and epidermal characters. Because Equisetum generally grows in wet conditions around water reservoirs, our findings indicate that the fossil locality was humid and surrounded by swamp and lowland regions during deposition. Ample fossil evidence indicates that this sphenopsid once existed in the western Himalaya during the Siwalik period. However, at present Equisetum is confined to a particular area of our fossil locality, probably a consequence of severe environmental changes coupled with competition from opportunistic angiosperms. Our discovery of Equisetum fossils in appreciable numbers from the Siwalik sediments of the Himachal Himalayas is unique and constitutes the first reliable recognition of Equisetum from the Indian Cenozoic.

Abstract
Purpose To determine the pattern of pediatric ocular morbidities in western India. Methods This was a retrospective longitudinal study that included all consecutive children aged ≤15 years who presented to the outpatient department of a tertiary eye center for the first time. Patient demographics, best-corrected visual acuity (BCVA), and ocular examination data were compiled. Subgroup analysis was also performed based on age group (years): ≤5, 5-10, and >10-15. Results A total of 11,126 eyes of 5563 children were included in the study. The mean age of the study population was 5.15 (±3.32) years with males (57.07%) being predominant. Approximately half of the patients (50.19%) were under the age of 5 years, followed by those aged 5-10 years (45.1%) and >10-15 years (4.71%). Among the study eyes, the BCVA was ≥20/60 in 58.57%, indeterminable in 35.16%, and <20/60 in 6.71%. The commonest ocular morbidity noted was refractive error (28.97%) followed by allergic conjunctivitis (7.64%) and strabismus (4.95%) in the total study cohort and also after age stratification. Conclusion Refractive error, allergic conjunctivitis, and strabismus are the major causes of ocular morbidity in pediatric eyes at a tertiary care center. Planning screening programs at the regional and national levels is crucial to decreasing the burden of eye disorders. These programs also need to have a suitable referral mechanism established and be smoothly connected to primary and secondary health-care centers. This will help to assure quality eye care delivery, while also reducing the strain of overworked tertiary centers.

Abstract
The tropical cyclones impact both the eastern and western coasts of India, causing severe socio-environmental problems. This study analyzed shoreline changes and vegetation degradation caused by cyclone Nisarga and monsoon events in Maharashtra coastal zone and Mumbai region, India. In this study, the shoreline change was studied using the Net Shoreline Movement (NSM) statistical technique embedded in the digital shoreline analysis system (DSAS) tool. The effects of the cyclone on the vegetation were mapped using the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and the rainfall distribution from Global Precipitation Measurement (GPM) data. The correlation between rainfall data and vegetation loss was analyzed using geographically weighted regression. The results also show that 90% of the events were concentrated in the 80-300 mm classes, being classified as sudden increases. This cyclone caused erosion in 56.32% of the shoreline; the highest erosion level was observed along the coastal zone of Maharashtra (near Mumbai city). Cyclone Nisarga has also impacted the vegetation loss most prominently in the region, with mean EVI in pre-cyclone equal to 0.4 and post-cyclone equal to 0.2. These eco-physical studies using geospatial technology are needed to understand the behavior of changes in shoreline and vegetation and can also help coastal managers plan for resilient coastal systems after the passage of tropical cyclones.

Abstract
BACKGROUND CYP3A5 enzymes belong to the phase I Group of drug-metabolizing enzymes, which are involved in the metabolism of 50% of the drugs. Participants with CYP3A5 genotype: CYP3A5 *1/*1 are fast metabolizers of drugs and hence will require higher dosing. Whereas those with CYP3A5 * 3/*3 are poor metabolizers of drugs and will require a lower dose to achieve target drug concentration in the blood and those with CYP3A5 * 1/*3 have intermediate drug metabolizing activity. Pharmacogenetic evaluation may improve disease outcomes by maximizing the efficacy and minimizing the toxicity of drugs in patients. MATERIALS AND METHODS This is a single-center cross-sectional study conducted in the year 2018-2019 to study the population prevalence of genetic polymorphisms of CYP3A5 in healthy participants from western India. Eligible participants willing to give written, informed consent were enrolled in the study. Subsequently, 2 ml venous blood was collected the deoxyribonucleic acid was extracted and then stored at ‒20°C. Genotyping was done by a polymerase chain reaction and restriction fragment length polymorphism. RESULTS A total of 400 participants with a median age of 22 years (range: 18-58 years) were included. Among them, the genotype prevalence for CYP3A5 * 1/*1 was 17% (n = 67/400); CYP3A5 * 1/*3 was 37% (n = 149/400) and that of CYP3A5 * 3/*3 was 46% (184/400). Out of the total 400 healthy participants analyzed, the allele frequency for CYP3A5 * 1 was 35% (142/400) and that of CYP3A5*3 was 65% (259/400). CONCLUSION The genotype prevalence for CYP3A5 * 3*3 (46%) and the allele frequency for CYP3A5 * 3 (65%) respectively were the highest among the western Indian population.

Abstract
Background: While the past decades have seen a rise in the number of cases diagnosed with cancer, breast cancer in particular has become the most frequently diagnosed cancer in women over the past decade. The figures for associated mortality are on a decline in most Western and developed nations, but in contrast they continue to remain high in transitional nations like India. Materials and Methods: After receiving approval by IEC and IRB, we set-up a prospective 2-year long screening programme combined with outreach camps to ensure representation of the larger population and include urban, rural and tribal population. Strict screening criteria were enforced and trained female paramedical staff were assigned to the camp for patient counselling and breast cancer awareness. Investigation was performed at the tertiary care institute utilising both full-field digital breast mammography and tomosynthesis. Biopsy was advised for highly suspicious lesions. Results: The study encompassed n=1017 Indian women and revealed that 39% (n=397) of them belonged to 41-50 years age group. BIRADS categorisation of the lesions revealed that while majority (57%; n=580) women had no detectable abnormality, nearly 22% (n=224) had lesions suspected to be benign while 10% (n=99) of them had lesions with a suspicion of high index of malignancy. 43% (n=437) of the populace had dense breasts (type-C). Most of the BIRADS-5 lesions (36/38) were confirmed as malignant on histopathology. Conclusion: We propose a model for screening mammography and also presents the results of this programme which we implemented to screen populace from a large and densely populated geographic region. The model was successful in being self-sustainable and received a good turnout on the back of community outreach breast awareness camps and by incentivizing the women by performing mammograms completely free of cost and also providing them reports.

Abstract
Sustainable management of groundwater resources requires detailed basin-wide water assessments. Semi-urbanized areas surrounding metropolitan cities in the western part of India were assessed for their suitability for domestic, irrigation, and industrial purposes. These study areas reflect rapid urban growth with residential complexes, combined with agricultural, horticultural, and industrial uses. Therefore, 68 representative groundwater samples were collected during the pre-monsoon (PRM) and post-monsoon (POM) seasons of 2015 and analyzed for major ions. According to the World Health Organization (WHO) drinking standards, parameters like EC, TDS, TH, HCO3, Ca, and Mg were found to exceed the desirable maximum limits, and the B and F content exceeded the permissible limits. The drinking suitability was studied using the modified water quality index (MWQI). The irrigation suitability was assessed using indices such as sodium adsorption ratio (SAR), percent sodium (%Na), and permeability index (PI). The industrial suitability was evaluated based on Langelier saturation index (LSI), saturation index (SI), Ryznar stability index (RSI), etc. MWQI results corroborate that 52.94 and 70% samples fall in no pollution category, and 47% and 30% samples were identified to be in the moderate category of pollution in the PRM season and POM season, respectively. The spatial variation maps of LSI, SI, RSI, Puckorius scaling index (PSI) and Larson-Skold index (LaI) show that the majority of the samples in the PRM season have low to insignificant scaling and corrosive potentials as compared to POM samples. The study results provide reliable information for water reserve managers to prepare the sustainable and more accurate basin management plans.

Abstract
Renal cell carcinoma (RCC) accounts for 3% of all adult cancers and 85% of all kidney tumours. Incidence of RCC is lower in Asian region, particularly in India, probably due to lack of reporting. Most of the data about RCC are from Western countries; and data from India are scarce, especially regarding para-neoplastic syndromes. We sought to determine the epidemiology, clinicopathological profile and management of RCC in a tertiary care centre in Western India. This was a retrospective study that involved data analysis of records of RCC patients who presented to our institution from April 2016 to February 2020. Laboratory investigations, including tests for paraneoplastic syndrome (PNS), and relevant radiologic investigations were performed and treatment was offered according to the stage, patient factors and available modalities. A total 142 RCC patients were included in the study. The median age of presentation was 58 years. Most of the patients (67%) were symptomatic, and 33% of the patients were asymptomatic, and the RCC was diagnosed incidentally. A large number of patients (56.3%) had PNS. The most common histopathologic type of RCC was clear cell carcinoma (68.8%), followed by papillary (20%) and chromophobe (8%) carcinoma. 40% of carcinomas with sarcomatoid differentiation were seen in patients under 50 years of age. Two cases of multicystic RCC were both seen in patients less than 50 years of age. 65.5% of the patients presented at Stage 1 and 2. Most surgeries (71.2%) were done in a minimally invasive manner. A significant number of patients were asymptomatic, in which RCC was detected incidentally. The age of presentation was earlier, yet the patients had a higher tumour stage. More than half of the patients had PNSs. Despite growing trend towards Western data, the significantly higher number of patients with PNSs and early age of presentation suggest inherent differences in tumour biology, possibly related to differences in genetic and environmental factors.

Abstract
Reduction in seroprevalence of Hepatitis A virus (HAV) is known to be associated with improvements in socioeconomic conditions of the community. National Institute of Virology, Pune has been studying seroprevalence of hepatitis viruses in Pune region over the past four decades. In total, 1438 samples were collected from urban general (UGEN), urban lower socioeconomic stratum (ULSES) and rural (RURAL) populations of the Pune district. Based on estimates in previous studies, subjects were enrolled from age groups ‘6–10’, ‘15–25’ and ‘40 + ’ years. HAV seroprevalence in younger population showed a significant decline. A significant decline in HAV seroprevalence in ‘15–25’ years age group in UGEN (from 85.9% to 73.9%; OR = 0.46, 95% CI: 0.25–0.86) and RURAL (from 98.6% to 91.4%; OR = 0.15, 95% CI: 0.05–0.45) populations suggested that the trend probably started more than a decade ago. Seroprevalence of HAV among ULSES ‘6–10’ children was found to be significantly higher (70.4%) than that among the RURAL children (44.2%; OR = 3.0, 95%CI: 1.7–5.2) and UGEN children (40.4%; OR = 3.5, 95%CI: 1.8–6.7). In view of increasing rates of urbanisation in India, ULSES population needs special consideration while designing future studies and viral hepatitis vaccination/elimination strategies. Our findings call for robust population-based studies that consider heterogeneity within populations and dynamics of socio-economic parameters in various regions of a country.

Abstract
Cervical Cancer is the second most leading cause of death among Indian women. Infection by human papillomavirus (HPV) is one of the major causes of cervical cancer. Two prophylactic HPV vaccines approved and recommended for adolescents and young women in India. However, due to lack of appropriate knowledge, education, resources, and proper communication, these tools have little impact on disease burden. It is important to understand attitude, knowledge, and beliefs of females about HPV, cervical cancer, and HPV vaccine. Hence, the present study aimed to check awareness, educate females about cervical cancer and HPV vaccine, and evaluate the major hurdles in acceptability of HPV vaccine. Total 693 females of age 16 to 40 years of diverse background were enrolled in the study. Questionnaires were prepared to assess knowledge about cervical cancer and HPV vaccine before and after education and impact of knowledge on willingness to administer the vaccine. Education was given with the help of concern physicians. Final follow-up was done after 1 month to assess the attitude towards vaccination. The overall awareness before education was found to be 20.63%; maximum in females of medical (51.37%), and paramedical background (33.33%). Improvement after education was observed in terms of improved information about etiology, symptoms, precautions, and vaccination for cervical cancer. Acceptability of HPV vaccine was found to be poor (40.11% refused to undergo vaccination and 32.17% were in dilemma/unable to decide). Besides religious beliefs, high cost of the vaccine and unavailability of proper and convincing information about the vaccine would be the chief reasons for poor acceptability of HPV vaccine.

Abstract
Canine parvovirus (CPV) has emerged as an acute pathogen of young canine causing haemorrhagic enteritis and myocarditis. It is widely distributed and underreported in India. Therefore the study was conducted to type the CPV circulating in western Maharashtra. The faecal samples (n = 150) from clinically ill dogs showing diarrhoea and vomition were collected and subjected to haemagglutination (HA) with porcine RBC's. The DNA was extracted from the samples showing HA titres above 64 and subjected for amplification of VP2 gene fragment by PCR. The amplicons were subjected for restriction fragment length polymorphism (RFLP), sequencing and BEAST phylogenetic analysis. The results revealed 6% positivity by PCR. The RFLP results indicated single cleavage site for ApaLI and HinfI with an exception of two sites for HinfI. The nucleotide sequences showed nonfunctional nucleotide changes at different locations. The sequence analysis indicated that the nucleotide divergence within isolates under study was 0.00-0.42%, while the nucleotide homology was 99.58-100%. The most recent common ancestor was determined by molecular clock analysis using Bayesian methods. The sequence and phylogenetic analysis suggested the isolates as CPV-2a and KATN1 (KU866391, 2014) isolate from Tamilnadu, India as time to most recent common ancestor (TMRCA). The results revealed the circulating CPV in canines from western India as CPV2a genotype.

Abstract
Janani-Shishu Suraksha Karyakram (JSSK) and Janani Suraksha Yojana (JSY) were launched with the objective of increasing institutional deliveries. But, its knowledge among the post-natal mothers is not known. This research evaluated the knowledge of two national health programs among post-natal mothers and found out the predictors of good knowledge about the entitlements of these programs. A cross-sectional study was conducted on a sample of consecutively recruited 339 post-natal mothers who had delivered in a tertiary care hospital of western India. Data were collected from November 2016 to February 2017 by interview method using a questionnaire with questions about knowledge regarding the entitlements of JSSK and JSY. Multivariable analysis was carried out for predictors of good knowledge. Among the 339 post-natal mothers, 30% had a good knowledge regarding JSSK. Only 24% had heard about JSSK; 54% knew regarding free transport to the place of delivery; only 22% and 13%, respectively knew about free inter-facility transport in case of complications for pregnant women and sick infants, while 96% knew regarding free drop-back facility. Only one-fourth of the mothers knew regarding monetary benefit under JSY, while 28% of them had actually received the benefit. The number of antenatal care visits, having an occupation and belonging to Hindu religion significantly predicts good knowledge among postnatal mothers regarding JSSK. Knowledge among the post-natal mothers regarding the entitlements of JSSK and JSY is less while comparing with published literature and needs improvement. Regular ante-natal care (ANC) visits might improve their knowledge of these programs. There is a need to create awareness among hospital staff for the provision of reimbursement of costs incurred by post-natal mothers. There is also a need to carry out demand generation activities among mothers regarding the entitlements of JSSK and JSY.

Abstract
Macrothrombocytopenia is being increasingly described across the globe. There is paucity of data on the prevalence of this condition from different parts of India. 10,047 healthy college students from the city of Surat in western India were investigated for macrothrombocytopenia i.e. those with Mean platelet Volume of > 11 fL and platelet count of less than 150 × 109/L. ABO blood groups, complete blood counts, peripheral smear examination and haemoglobinopathy work up was also done. Siblings and parents of the macrothrombocytopenic individuals were also studied when available. Bleeding assessment tool of International society of thrombosis and haemostasis were applied to see if there were excessive bleeding in macrothrombocytropenia patients. One hundred and ninety-six students (1.95%) had asymptomatic macrothrombocytopenia. More female students (P < 0.0001) had this condition and blood group A was under represented (P = 0.019) with this condition. Prevalence of macrothrombocytopenia was not related to ethnic subgroups to which the students belonged to, nor was it linked to presence of any haemoglobinopathy gene. In 38 of the 52, 1st degree relatives studied macrothrombocytopenia was confirmed at least in one of them. Excessive bleeding in none of the individuals with macrothrombocytopenia was noted. Asymptomatic macrothrombocytopenia is rare in western parts of India and affects 1.95% of the healthy population. Females were over represented with this condition raising a suspicion of X linked dominant inheritance. Underrepresentation of blood group A in this condition requires further study.

Abstract
Since 2003, India has had a well-established influenza surveillance network, though Influenza C virus was not the focus of study. We therefore retrospectively analyzed clinical samples from Pune, western India collected during January 2009 to August 2015, by real-time RT-PCR. Three of 2530 samples of patients with influenza-like illness (ILI) or severe acute respiratory illness (SARI) showed positivity for Influenza C virus infection, while 105 and 31 samples were positive for Influenza A and B viruses respectively. Influenza C viruses were successfully isolated using the embryonated egg system and whole genomes were sequenced and analyzed phylogenetically. HE gene-based phylogeny showed that two viruses C/India/P119564/2011 and C/India P121719/2012 clustered with the C/Sao Paulo/378/82 (SP82) lineage, whereas C/India/P135047/2013 clustered with the C/Kanagawa/1/76 (KA76) lineage. The internal gene of these viruses grouped in two lineages. The PB1, PB2, M and NS genes of the study viruses grouped with C/Yamagata/26/81 (YA81), while the P3 (PA) and NP genes grouped with C/Mississippi/80 (MS80). Bayesian clock studies conclude that the Indian strains may have emerged through multiple reassortment events.

Abstract
Aerosol optical properties are analyzed for the first time over Desalpar (23.74°N, 70.69°E, 30m above mean sea level) a remote site in western India during October 2014 to August 2015. Spectral aerosol optical depth (AOD) measurements were performed using the CIMEL CE-318 automatic Sun/sky radiometer. The annual-averaged AOD500 and Ångström exponent (α440-870) values are found to be 0.43±0.26 and 0.69±0.39, respectively. On the seasonal basis, high AOD500 of 0.45±0.30 and 0.61±0.34 along with low α440-870 of 0.41±0.27 and 0.41±0.35 during spring (March-May) and summer (June-August), respectively, suggest the dominance of coarse-mode aerosols, while significant contribution from anthropogenic sources is observed in autumn (AOD500=0.47±0.26, α440-870=1.02±0.27). The volume size distribution and the spectral single-scattering albedo also confirm the presence of coarse-mode aerosols during March-August. An overall dominance of a mixed type of aerosols (~56%) mostly from October to February is found via the AOD500 vs α440-870 relationship, while marine aerosols contribute to ~18%. Spectral dependence of α and its second derivative (α') are also used for studying the aerosol modification processes. The average direct aerosol radiative forcing (DARF) computed via the SBDART model is estimated to range from -27.08Wm-2 to -10.74Wm-2 at the top of the atmosphere, from -52.21Wm-2 to -21.71Wm-2 at the surface and from 10.97Wm-2 to 26.54Wm-2 within the atmosphere. This atmospheric forcing translates into heating rates of 0.31-0.75Kday-1. The aerosol properties and DARF are also examined for different trajectory clusters in order to identify the sources and to assess the influence of long-range transported aerosols over Desalpar.

Abstract
Acute gastroenteritis is a leading cause of mortality in children from developing countries. Recently, Salivirus has been frequently detected in acute gastroenteritis patients, suggesting its possible aetiological role. Conflicting reports available on disease association of Salivirus have made it difficult to ascertain their causative role. The overall epidemiology and clinical features of Salivirus infections are poorly understood. The present five year study was undertaken to investigate the presence and genetic diversity of Salivirus in acute gastroenteritis cases from Pune, Western India and to determine the clinico-epidemiological features of Salivirus infections. A total of 985 faecal samples (778 acute gastroenteritis and 207 asymptomatic controls), collected from three local hospitals (Jan2007-Dec2011) were examined for the presence of Salivirus by RT-PCR. Molecular characterization was performed by PCR amplification of the 3D and VP regions. Frequency of Salivirus detection in cases (2.6%) and controls (1.93%) was not significantly different (p = 0.57). Co-infection with other enteric viruses was seen in 50% of the cases. Comparison of clinical features between Salivirus mono and mixed infections revealed that Salivirus alone did not exacerbate gastroenteritis. The frequency of diarrhoea and overall clinical severity of mixed infections was significantly greater than mono infections (p = 0.02). Based on clinical findings, our study suggests that Salivirus does not cause severe gastroenteritis. Phylogenetic analysis indicated that study strains belonged to Salivirus A1 and formed 2 distinct clusters which shared nucleotide identities of 94.1-96.2% and 88.9-93.8% between themselves in 3D and VP regions, respectively. Interestingly, the more divergent Cluster2 strains shared a low nucleotide identity with the closest reference strain in both regions (~95% in 3D and ~92% in VP) suggesting that they could represent a variant type of Salivirus A1. The genetic diversity in strains detected from study region, emphasizes the need for Salivirus surveillance from other regions of India.

Abstract
BACKGROUND Obesity among adolescents is escalating as a global epidemic which is associated with various lifestyle disorders in later life. OBJECTIVE To assess the factors influencing overweight and obesity among school going adolescents of Vadodara city in Western India. METHODS The study was carried out among 1050 school going adolescents from 15 schools selected by systematic random sampling after taking written informed consent from the participants. A predefined pretested semi-structured questionnaire was used to collect dietary information and physical activity. Anthropometric measurements such as height, weight, triceps skin fold thickness, waist and hip circumferences was measured using standard techniques. Adolescents were classified as overweight (>+1SD) and obese (>+2SD) with respect to their age and sex by using WHO reference charts. Factors found to be statistically significant in bivariate analysis were considered in the multiple logistic regression model. RESULTS Among 1050 school going adolescents, 7.8% were overweight and 2.7% were obese, making the combined prevalence of overweight and obesity as 10.5%. Among socio-demographic predictors: early and mid adolescence, male gender, English medium of instruction, positive family history of obesity were found to be the significantly associated with overweight/obesity among the study population. Whereas consumption of outside food, meal skipping habit, infrequent consumption of staple healthy food items were found to be significant diet related predictor variables for overweight/obesity. Among the physical activity predictors: sedentary activities, less outdoor games and sleep deprivation were also found to be significant predictors of overweight/obesity. CONCLUSION Adolescents should be motivated to take adequate amount of healthy staple food like dal-rice at home and to engage in outdoor sports related activity to prevent overweight and obesity.

Abstract
BACKGROUND Psoriasis, a common autoimmune disorder characterized by T cell-mediated keratinocyte hyperproliferation, is known to be associated with the presence of certain specific Human Leukocyte Antigen (HLA) alleles. AIM To evaluate distribution of HLA-A and HLA-B alleles and hence identify the susceptible allele of psoriasis from patients in Western India. MATERIALS AND METHODS The study design included 84 psoriasis patients and 291 normal individuals as controls from same geographical region. HLA-A and HLA-B typing was done using Serology typing. Standard statistical analysis was followed to identify the odds ratio (OR), allele frequencies, and significant P value using Graphpad software. RESULTS The study revealed significant increase in frequencies of HLA-A2 (OR-3.976, P<0.0001), B8 (OR-5.647, P<0.0001), B17 (OR-5.452, P<0.0001), and B44 (OR-50.460, P<0.0001), when compared with controls. Furthermore, the frequencies of HLA-A28 (OR-0.074, P=0.0024), B5 (OR-0.059, P<0.0001), B12 (OR-0.051, P=0.0002), and B15 (OR-0.237, P=0.0230) were significantly decreased in psoriasis patients. CONCLUSION This study shows the strong association of HLA-A2, B8, and B17 antigens with psoriasis conferring susceptibility to psoriasis patients from Western India, while the antigens HLA-A28, B5, and B12 show strong negative association with the disease.
