Determinants of Recurrent Diarrhoea among Children

BackgroundAbout 2 million episodes of diarrhoea occur each year in India. Of the 6.6 million deaths among children aged 28 days to 5 year; deaths from diarrhoea are estimated to account for 1.87 million. An average Indian child less than 5 years of age can have 2-3 episodes of diarrhoea.  Mother's literacy, family income, feeding practices, environmental conditions are important determinants of the common childhood infection like diarrhoea. The present study was undertaken to study these important determinants of recurrent diarrhoea among children under five in a rural area of western Maharashtra, India.Method  A cross-sectional study was conducted in six randomly selected villages of Ahmednagar district in western Maharashtra, India. Three villages from two primary health centres and 652 children under five from these villages were chosen by a simple random sampling technique (every fifth child enrolled in Anganwadi). House-to-house survey was done and data was collected by interviewing the mothers of these children. Nutritional status was assessed by measuring the weight and mid-arm circumference of the child. Statistical analysis was done with Microsoft Excel and StatistiXL 1.8 using percentage, proportions and chi-square test wherever applicable.ResultsThe prevalence of recurrent diarrhoea was 9.81%. Recurrent diarrhoea was more common in the age group of 13 - 24 months (29.6%) and 25 – 36 months (23.4%) and children belonging to lower socioeconomic class (64%). Malnutrition was significantly associated with recurrent diarrhoea and 21% of malnourished children had the same. Recurrent diarrhoea was significantly more common (39.1%) among children with introduction of top-up feeds before four to six months.ConclusionLow socioeconomic status, bad sanitary practices, nutritional status and weaning practices significantly influence the prevalence of recurrent diarrhoea

Organic Tracers from Asphalt in Propolis Produced by Urban Honey Bees, Apis mellifera Linn.

Propolis is a gummy material produced by honey bees to protect their hives and currently has drawn the attention of researchers due to its broad clinical use. It has been reported, based only on observations, that honey bees also collect other non-vegetation substances such as paint or asphalt/tar to make propolis. Therefore, propolis samples were collected from bee hives in Riyadh and Al-Bahah, a natural area, Saudi Arabia to determine their compositional characteristics and possible sources of the neutral organic compounds. The samples were extracted with hexane and analyzed by gas chromatography-mass spectrometry. The results showed that the major compounds were n-alkanes, n-alkenes, methyl n-alkanoates, long chain wax esters, triterpenoids and hopanes. The n-alkanes (ranging from C17 to C40) were significant with relative concentrations varying from 23.8 to 56.8% (mean = 44.9±9.4%) of the total extracts. Their odd carbon preference index (CPI) ranged from 3.6 to 7.7, with a maximum concentration at heptacosane indicating inputs from higher plant vegetation wax. The relative concentrations of the n-alkenes varied from 23.8 to 41.19% (mean = 35.6±5.1%), with CPI = 12.4-31.4, range from C25 to C35 and maximum at tritriacontane. Methyl n-alkanoates, ranged from C12 to C26 as acids, with concentrations from 3.11 to 33.2%(mean = 9.6±9.5%). Long chain wax esters and triterpenoids were minor. The main triterpenoids were α- and β-amyrins, amyrones and amyryl acetates. The presence of hopanes in some total extracts (up to 12.5%) indicated that the bees also collected petroleum derivatives from vicinal asphalt and used that as an additional ingredient to make propolis. Therefore, caution should be taken when considering the chemical compositions of propolis as potential sources of natural products for biological and pharmacological applications. Moreover, beekeepers should be aware of the proper source of propolis in the flight range of their bee colonies

Smooth muscle hyperplasia due to loss of smooth muscle α-actin is driven by activation of focal adhesion kinase, altered p53 localization and increased levels of platelet-derived growth factor receptor-β

Mutations in ACTA2, encoding the smooth muscle cell (SMC)-specific isoform of α-actin (α-SMA), cause thoracic aortic aneurysms and dissections and occlusive vascular diseases, including early onset coronary artery disease and stroke. We have shown that occlusive arterial lesions in patients with heterozygous ACTA2 missense mutations show increased numbers of medial or neointimal SMCs. The contribution of SMC hyperplasia to these vascular diseases and the pathways responsible for linking disruption of α-SMA filaments to hyperplasia are unknown. Here, we show that the loss of Acta2 in mice recapitulates the SMC hyperplasia observed in ACTA2 mutant SMCs and determine the cellular pathways responsible for SMC hyperplasia. Acta2−/− mice showed increased neointimal formation following vascular injury in vivo, and SMCs explanted from these mice demonstrated increased proliferation and migration. Loss of α-SMA induced hyperplasia through focal adhesion (FA) rearrangement, FA kinase activation, re-localization of p53 from the nucleus to the cytoplasm and increased expression and ligand-independent activation of platelet-derived growth factor receptor beta (Pdgfr-β). Disruption of α-SMA in wild-type SMCs also induced similar cellular changes. Imatinib mesylate inhibited Pdgfr-β activation and Acta2−/− SMC proliferation in vitro and neointimal formation with vascular injury in vivo. Loss of α-SMA leads to SMC hyperplasia in vivo and in vitro through a mechanism involving FAK, p53 and Pdgfr-β, supporting the hypothesis that SMC hyperplasia contributes to occlusive lesions in patients with ACTA2 missense mutation

Pattern of injury in fatal road traffic accidents in a rural area of western Maharashtra, India

BackgroundFatal road traffic accidents (RTA) are a major cause of concern all over the world. The outcome of injuries sustained in an RTA depends on various factors including but not limited to: the location of the event, type of vehicle involved, nature of the roads, the time of accident, etc. AimsThis study aims to investigate and evaluate prospectively the socio-demographic profile and pattern of injuries in victims of  RTA in the rural area of district Ahmedanagar of Maharashtra state. MethodThis prospective study included all victims of road traffic accidents that presented to our emergency room from 1st June 2007 through 31st May 2009 and were either found dead on arrival or died during the treatment. All the included victims were autopsied at the post-mortem centre of Rural Medical College, Loni. ResultsNinety-eight victims of RTA were studied during the period. The most commonly affected age group was 20-39 years. Men died in RTA more than women. Fatal RTAs were more prevalent on the secondary road system (47.97 per cent) and especially involved pedestrian and two wheeler vehicle users. Large numbers (n=63, 64.28%) of victims either died on the scene or during transportation. Numbers of skeletal injuries (199) and internal organ injuries (202) exceeded the total number of victims (98) clearly indicating the multiplicity of injuries. The majority of RTA victims (n=46, 46.93%) died due to head injury. The study showed that most of the deaths in road traffic accidents, brought to a tertiary care rural hospital, took place either on the spot or within 24 hours of injury which is very alarming and highlights the need for taking urgent steps for establishing good pre-hospital care and provision of trauma services at site.ConclusionThere is an urgent nationwide need of computerized trauma registry to bring out the risk factors, circumstances, chain of events leading to the accidents and will be extremely helpful in policy making and health management at the national level in India

Metabolomic profiles delineate potential role for sarcosine in prostate cancer progression

Multiple, complex molecular events characterize cancer development and progression(1,2). Deciphering the molecular networks that distinguish organ- confined disease from metastatic disease may lead to the identification of critical biomarkers for cancer invasion and disease aggressiveness. Although gene and protein expression have been extensively profiled in human tumours, little is known about the global metabolomic alterations that characterize neoplastic progression. Using a combination of high- throughput liquid- and- gas- chromatography- based mass spectrometry, we profiled more than 1,126 metabolites across 262 clinical samples related to prostate cancer ( 42 tissues and 110 each of urine and plasma). These unbiased metabolomic profiles were able to distinguish benign prostate, clinically localized prostate cancer and metastatic disease. Sarcosine, an N- methyl derivative of the amino acid glycine, was identified as a differential metabolite that was highly increased during prostate cancer progression to metastasis and can be detected non- invasively in urine. Sarcosine levels were also increased in invasive prostate cancer cell lines relative to benign prostate epithelial cells. Knockdown of glycine- N- methyl transferase, the enzyme that generates sarcosine from glycine, attenuated prostate cancer invasion. Addition of exogenous sarcosine or knockdown of the enzyme that leads to sarcosine degradation, sarcosine dehydrogenase, induced an invasive phenotype in benign prostate epithelial cells. Androgen receptor and the ERG gene fusion product coordinately regulate components of the sarcosine pathway. Here, by profiling the metabolomic alterations of prostate cancer progression, we reveal sarcosine as a potentially important metabolic intermediary of cancer cell invasion and aggressivity.Early Detection Research Network ; National Institutes of Health ; MTTC ; Clinical Translational Science Award ; Fund for Discovery of the University of Michigan Comprehensive Cancer Center ; University of Michigan Cancer Biostatistics Training Grant ; Doris Duke Charitable FoundationWe thank J.

Clinical and molecular relevance of genetic variants in the non-coding transcriptome of patients with cytogenetically normal acute myeloid leukemia

Expression levels of long non-coding RNA (lncRNA) have been shown to associate with clinical outcome of patients with cytogenetically normal acute myeloid leukemia (CN-AML). However, the frequency and clinical significance of genetic variants in the nucleotide sequences of lncRNA in AML patients is unknown. Herein, we analyzed total RNA sequencing data of 377 younger adults (aged <60 years) with CN-AML, who were comprehensively characterized with regard to clinical outcome. We used available genomic databases and stringent filters to annotate genetic variants unequivocally located in the non-coding transcriptome of AML patients. We detected 981 variants, which are recurrently present in lncRNA that are expressed in leukemic blasts. Among these variants, we identified a cytosine-to-thymidine variant in the lncRNA RP5-1074L1.4 and a cytosine-to-thymidine variant in the lncRNA SNHG15, which independently associated with longer survival of CN-AML patients. The presence of the SNHG15 cytosine-to-thymidine variant was also found to associate with better outcome in an independent dataset of CN-AML patients, despite differences in treatment protocols and RNA sequencing techniques. In order to gain biological insights, we cloned and overexpressed both wild-type and variant versions of the SNHG15 lncRNA. In keeping with its negative prognostic impact, overexpression of the wild-type SNHG15 associated with higher proliferation rate of leukemic blasts when compared with the cytosine-to-thymidine variant. We conclude that recurrent genetic variants of lncRNA that are expressed in the leukemic blasts of CN-AML patients have prognostic and potential biological significance

Unusual Vascular Anatomy in a Human Cadaver

During the routine dissection in the Department of Anatomy of Rural Medical College, Loni, we found a rare variation in branching pattern of common carotid artery (CCA) and external carotid artery (ECA) bilaterally. The knowledge of possible anatomical variations of CCA and ECA are especially important in surgery of head, neck and face; and also for radiologist to understand and interpret cerebral angiography. The case is reported here and the clinical significance of this variation is emphasized

Traditional fishing activities enhance the abundance of selected waterbird species in a wetland in India

Abstract Background Waterbirds are globally declining as a result of habitat loss, alteration or degradation. Fishing activities may affect waterbird distribution, abundance and diversity, and traditional fishing activities often enhance waterbird abundance. We tested this hypothesis by studying the abundance and diversity of selected common waterbird species in the Kadalundi–Vallikkunnu Community Reserve, a globally significant wetland in southwestern India in relation to fishing activities. Methods We monitored waterbird abundance four times a month from 2012 to 2015 using direct observation method during low tide. Traditional bamboo fish traps were deployed during the first and third weeks of each month. ANOVAs (one-way and multi-way) were used to examine how waterbird counts diversity varied in relation to years, seasons and period of fishing traps. Additionally we conducted a linear regression to examine the relationship between fish occurrence and waterbird counts and diversity. Results Waterbird counts varied with years and seasons, with the maximum counts being recorded during the post-monsoon (winter). Individual species varied in their responses to trap deployment. Small waterbird species usually forage in shallow shorelines, increased during trap deployment whereas the larger waterbirds were not affected by trap deployment because they tend to hunt in deeper waters. The total fish captured was an important predictor of both waterbird abundance and diversity. Conclusion In this study we documented a positive association between traditional fish trap deployment and waterbird counts and diversity. Providing high quality habitats for waterbirds as well as effective sustainable livelihoods through traditional fisheries is a critical management issue

ENT Disorders- a Study from Rural India

BackgroundThere is a lack of data on paediatric otorhinolaryngology from various Indian populations. This study was undertaken to determine the hospital prevalence of ENT disorders in paediatric population and their relationship with sociodemographic factors in a rural tertiary care hospital in India. Method  A record based, retrospective study conducted at Rural Medical College and Pravara Rural Hospital, Loni which provides tertiary level health care facilities in western Maharashtra, India. The entire paediatric patients reporting to the Outpatient Department of ENT (Ear Nose Throat) during the calendar year 2009 was eligible for inclusion.ResultsENT diseases in our study population were found to be more common among male children (53.2%). Majority of the paediatric patients belonged to age group 5-14 years (66.3%), were from lower socioeconomic status (61.2%), living in nuclear family (71.3%) and had illiterate mothers (70.8%). Diseases of auditory system (57.3%) were the most common group of ENT problems among the paediatric population, followed by pharyngoesophageal (27.4%) and nasal (15.3%) disorders. The most common ear, nose and throat disorders were otitis media (18.25%), rhinitis (5.8%) and tonsillitis (11.7%) respectively.ConclusionThe study suggests that otitis media, tonsillitis and rhinitis are the most common otorhinolaryngological problems in paediatric population visiting the ENT department of this hospital and contribute significantly to paediatric morbidity. The results from this study cannot be applied to the community as prevalence of these morbidities is likely to be even higher in the general population.
