A rare case of peritoneo-cutaneous fistula after cesarean section

Peritoneo-cutaneous fistula is usually a rare but known entity. Such a case has not been reported after cesarean sections. A 26-year female presented to our clinic in May 2019 with persistent sero-purulent discharge from sinus over abdominal skin. The patient had previously undergone a cesarean section in April 2018 for premature rupture of membranes and non-progress of labour. The surgery and puerperal period were uneventful. The patient presented with document high-grade fever in June 2018. In August 2018, a localized painful swelling was noted by the patient herself over the abdomen, contrast-enhanced computed tomography, which suggested 6.3×3.9×3 cm collection in the right adnexal region and a fistulous tract communicating with abdominal skin. For the same she underwent surgery, wide local excision of the fistulous tract around elliptical skin incision was done. The development of delayed peritoneo-cutaneous fistula has been seen as a complication of difficult cholecystectomy

Electronic Cigarette Use Prevalence, Associated Factors, and Pattern by Cigarette Smoking Status in the United States From NHANES (National Health and Nutrition Examination Survey) 2013-2014

BACKGROUND: To examine the prevalence and patterns of recent electronic cigarette (e-cigarette) use in a nationally representative sample of US adults and adolescents. METHODS AND RESULTS: Using tobacco information from NHANES (National Health and Nutrition Examination Survey) 2013-2014, 5423 adults and 895 adolescents (aged 13-17 years) were included in this analysis. Demographic, tobacco use, and drug use information were self-reported. Recent e-cigarette use (within the previous 5 days) was stratified by smoking status. Of 125 e-cigarette users, 116 participants were aged ≥18 years, corresponding to 2.6% (95% confidence interval [CI], 2.0-3.1) and 1.21% (95% CI, 0.3-2.1) prevalence of e-cigarette use among US adults and adolescents, respectively. E-cigarette adult users were current smokers (68.1%), former smokers (23.7%), and never smokers (8.2%). The highest prevalence of e-cigarette use was among current smokers (8.2%; 95% CI, 6.3-10.1), followed by former smokers (2.7%; 95% CI, 1.4-4.1), and then never smokers (0.4%; 95% CI, 0.2-0.6). After adjusting for age, sex, and ethnicity, e-cigarette users had higher odds of being exposed to secondhand smoke (odds ratio: 6.3; 95% CI, 3.6-11.1) and drinking alcohol (odds ratio: 4.2; 95% CI, 1.8-10.0) and lower odds of having at least a college education or a higher income, compared with tobacco nonusers. CONCLUSIONS: Between 2013 and 2014, e-cigarette use in the United States was more common among younger people, those with low socioeconomic status, and current and former smokers. These findings will help inform future research as well as public policy and regulatory actions

A prospective observational study to determine the utility of placental laterality for prediction of preeclampsia in pregnancy

Background: Preeclampsia is a multisystem disorder of unknown aetiology and recently its link with placental laterality has been explored. The objective of this study was to find the association of placental laterality with maternal and fetal outcomes in pregnancy. Study also determined the predictive ability of placenta laterality for the development of hypertension in pregnancy.Methods: A prospective observational cohort study was conducted on 200 pregnant women. Routine investigations and doppler analysis were done. Placenta position was categorized into central and lateral. Maternal and fetal outcomes were recorded. The data was entered in MS excel spreadsheet and analysis was done using statistical package for social sciences (SPSS) version 21.0. A p value of 0.05). Even the maternal outcomes like mode of delivery, onset of labor, indication of labor induction and caesarean deliveries were comparable among women with central or lateral placenta (p > 0.05). On applying univariate logistic regression analysis, previous history of hypertension in pregnancy was a significant risk factor for development of preeclampsia with odds ratio of 168.43 (p < 0.05).Conclusions: It can be concluded that the maternal and fetal outcomes are independent of the placenta laterality. The doppler characteristics and placenta laterality did not show any increased risk for hypertension in pregnancy. However future studies are recommended with large sample size including more women with diagnosed hypertension in the pregnancy so that a better association can be derived with placenta laterality and doppler characteristics

Study of incidence and severity of menopausal symptoms in women of sub Himalayan region, using the Greene Climacteric Scale

Background: Identifying and measuring menopausal symptoms using Greene Climacteric Scale and calculating the mean age at menopause to find out the frequency of the menopausal symptoms so that can be used for better perimenapausal and menopausal care to females.Methods: A cross-sectional study was conducted in a tertiary care center in northern India. All menopausal women in gynaecology outpatient department were enrolled in study, over six months from May 2019 to October 2019. A total of 206 women fulfilled the inclusion criteria and were interviewed using the 21 points Greene Climateric Scale (GCS) Questionnaire. Analysis was done using SPSS 20 Windows software. Descriptive statistics included computation of percentages, means and standard deviations. Level of significance was set at P≤0.05.Results: The mean age of menopause was 47.9±3.42 years. About 90.3% of the menopausal women studied belonged to the rural population. The most frequently perceived symptoms by females were muscle joint pain (100%), vaginal dryness and pruritus vulvae (84%), lower abdominal pain (79.6%), hot flushes (50.5%).The most frequently reported symptoms as per the GCS were muscle and joint pains, loss of interest in sex, headaches, feeling tired or lacking in energy, difficulty in concentrating, attacks of anxiety, difficulty in sleeping and hot flushes. The mean total score was 17.61.Conclusions: Menopausal symptoms were common in this study group but women seeking help for the same was less. Therefore menopause clinics and care programmes need to be developed and strengthened to promote better health and higher quality of life in menopausal women

Orai1 inhibitor STIM2?? regulates myogenesis by controlling SOCE dependent transcriptional factors

Store-operated Ca2+ entry (SOCE), the fundamental Ca2+ signaling mechanism in myogenesis, is mediated by stromal interaction molecule (STIM), which senses the depletion of endoplasmic reticulum Ca2+ stores and induces Ca2+ influx by activating Orai channels in the plasma membrane. Recently, STIM2??, an eight-residue-inserted splice variant of STIM2, was found to act as an inhibitor of SOCE. Although a previous study demonstrated an increase in STIM2?? splicing during in vitro differentiation of skeletal muscle, the underlying mechanism and detailed function of STIM2?? in myogenesis remain unclear. In this study, we investigated the function of STIM2?? in myogenesis using the C2C12 cell line with RNA interference-mediated knockdown and CRISPR-Cas-mediated knockout approaches. Deletion of STIM2?? delayed myogenic differentiation through the MEF2C and NFAT4 pathway in C2C12 cells. Further, loss of STIM2?? increased cell proliferation by altering Ca2+ homeostasis and inhibited cell cycle arrest mediated by the cyclin D1-CDK4 degradation pathway. Thus, this study identified a previously unknown function of STIM2?? in myogenesis and improves the understanding of how cells effectively regulate the development process via alternative splicing

A comparative study of efficacy of oral pregabalin and clonidine for attenuation of pressor response to intubation

Background: Endotracheal intubation is associated with hemodynamic stress responses. Various drugs have been used in the past to attenuate the pressor response; however, none has been proved to be ideal. Present study was planned to evaluate the oral pregabalin 150 mg and clonidine 200 µg for attenuation of pressor response to intubation.Methods: The study was conducted on 100 adult patients of either gender scheduled to undergo elective surgeries under general anaesthesia (GA). The patients were randomly allocated into 2 groups. In group A patients received pregabalin 150mg and in group B patients received clonidine 200µg orally. The hemodynamic parameters were recorded until 10 minutes after intubation. The sedation, anxiety and side effects were also assessed.Results: In clonidine group, the mean HR remained below the baseline value at all the time intervals. In pregabalin group, the mean HR remained below the baseline value at most of the time intervals but increased above baseline just after intubation (T0i) and 1 minute after intubation (T1i) where increase was only 1.488±1.20% and 0.45±1.16% respectively from baseline. In both pregabalin and clonidine groups, the mean SBP and MAP remained below the baseline value (Tb) at all the time intervals from T0.5 to T10i. Both clonidine and pregabalin provided adequate anxiolysis and sedation with pregabalin providing more pronounced sedation and anxiolysis than clonidine.Conclusions: Both clonidine and pregabalin are effective oral premedication drugs for attenuation of the pressor response to laryngoscopy and endotracheal intubation.

Alternative splicing converts STIM2 from an activator to an inhibitor of store-operated calcium channels

Store-operated calcium entry (SOCE) regulates a wide variety of essential cellular functions. SOCE is mediated by STIM1 and STIM2, which sense depletion of ER Ca2+ stores and activate Orai channels in the plasma membrane. Although the amplitude and dynamics of SOCE are considered important determinants of Ca2+-dependent responses, the underlying modulatory mechanisms are unclear. In this paper, we identify STIM2??, a highly conserved alternatively spliced isoform of STIM2, which, in contrast to all known STIM isoforms, is a potent inhibitor of SOCE. Although STIM2?? does not by itself strongly bind Orai1, it is recruited to Orai1 channels by forming heterodimers with other STIM isoforms. Analysis of STIM2?? mutants and Orai1-STIM2?? chimeras suggested that it actively inhibits SOCE through a sequence-specific allosteric interaction with Orai1. Our results reveal a previously unrecognized functional flexibility in the STIM protein family by which alternative splicing creates negative and positive regulators of SOCE to shape the amplitude and dynamics of Ca2+ signals.open

Genome-Wide Distribution and Organization of Microsatellites in Plants: An Insight into Marker Development in Brachypodium

Plant genomes are complex and contain large amounts of repetitive DNA including microsatellites that are distributed across entire genomes. Whole genome sequences of several monocot and dicot plants that are available in the public domain provide an opportunity to study the origin, distribution and evolution of microsatellites, and also facilitate the development of new molecular markers. In the present investigation, a genome-wide analysis of microsatellite distribution in monocots (Brachypodium, sorghum and rice) and dicots (Arabidopsis, Medicago and Populus) was performed. A total of 797,863 simple sequence repeats (SSRs) were identified in the whole genome sequences of six plant species. Characterization of these SSRs revealed that mono-nucleotide repeats were the most abundant repeats, and that the frequency of repeats decreased with increase in motif length both in monocots and dicots. However, the frequency of SSRs was higher in dicots than in monocots both for nuclear and chloroplast genomes. Interestingly, GC-rich repeats were the dominant repeats only in monocots, with the majority of them being present in the coding region. These coding GC-rich repeats were found to be involved in different biological processes, predominantly binding activities. In addition, a set of 22,879 SSR markers that were validated by e-PCR were developed and mapped on different chromosomes in Brachypodium for the first time, with a frequency of 101 SSR markers per Mb. Experimental validation of 55 markers showed successful amplification of 80% SSR markers in 16 Brachypodium accessions. An online database ‘BraMi’ (Brachypodium microsatellite markers) of these genome-wide SSR markers was developed and made available in the public domain. The observed differential patterns of SSR marker distribution would be useful for studying microsatellite evolution in a monocot–dicot system. SSR markers developed in this study would be helpful for genomic studies in Brachypodium and related grass species, especially for the map based cloning of the candidate gene(s)

Global, regional, and national under-5 mortality, adult mortality, age-specific mortality, and life expectancy, 1970–2016: a systematic analysis for the Global Burden of Disease Study 2016

BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and sex-specific all-cause mortality between 1970 and 2016 for 195 countries and territories and at the subnational level for the five countries with a population greater than 200 million in 2016. METHODS: We have evaluated how well civil registration systems captured deaths using a set of demographic methods called death distribution methods for adults and from consideration of survey and census data for children younger than 5 years. We generated an overall assessment of completeness of registration of deaths by dividing registered deaths in each location-year by our estimate of all-age deaths generated from our overall estimation process. For 163 locations, including subnational units in countries with a population greater than 200 million with complete vital registration (VR) systems, our estimates were largely driven by the observed data, with corrections for small fluctuations in numbers and estimation for recent years where there were lags in data reporting (lags were variable by location, generally between 1 year and 6 years). For other locations, we took advantage of different data sources available to measure under-5 mortality rates (U5MR) using complete birth histories, summary birth histories, and incomplete VR with adjustments; we measured adult mortality rate (the probability of death in individuals aged 15-60 years) using adjusted incomplete VR, sibling histories, and household death recall. We used the U5MR and adult mortality rate, together with crude death rate due to HIV in the GBD model life table system, to estimate age-specific and sex-specific death rates for each location-year. Using various international databases, we identified fatal discontinuities, which we defined as increases in the death rate of more than one death per million, resulting from conflict and terrorism, natural disasters, major transport or technological accidents, and a subset of epidemic infectious diseases; these were added to estimates in the relevant years. In 47 countries with an identified peak adult prevalence for HIV/AIDS of more than 0·5% and where VR systems were less than 65% complete, we informed our estimates of age-sex-specific mortality using the Estimation and Projection Package (EPP)-Spectrum model fitted to national HIV/AIDS prevalence surveys and antenatal clinic serosurveillance systems. We estimated stillbirths, early neonatal, late neonatal, and childhood mortality using both survey and VR data in spatiotemporal Gaussian process regression models. We estimated abridged life tables for all location-years using age-specific death rates. We grouped locations into development quintiles based on the Socio-demographic Index (SDI) and analysed mortality trends by quintile. Using spline regression, we estimated the expected mortality rate for each age-sex group as a function of SDI. We identified countries with higher life expectancy than expected by comparing observed life expectancy to anticipated life expectancy on the basis of development status alone. FINDINGS: Completeness in the registration of deaths increased from 28% in 1970 to a peak of 45% in 2013; completeness was lower after 2013 because of lags in reporting. Total deaths in children younger than 5 years decreased from 1970 to 2016, and slower decreases occurred at ages 5-24 years. By contrast, numbers of adult deaths increased in each 5-year age bracket above the age of 25 years. The distribution of annualised rates of change in age-specific mortality rate differed over the period 2000 to 2016 compared with earlier decades: increasing annualised rates of change were less frequent, although rising annualised rates of change still occurred in some locations, particularly for adolescent and younger adult age groups. Rates of stillbirths and under-5 mortality both decreased globally from 1970. Evidence for global convergence of death rates was mixed; although the absolute difference between age-standardised death rates narrowed between countries at the lowest and highest levels of SDI, the ratio of these death rates-a measure of relative inequality-increased slightly. There was a strong shift between 1970 and 2016 toward higher life expectancy, most noticeably at higher levels of SDI. Among countries with populations greater than 1 million in 2016, life expectancy at birth was highest for women in Japan, at 86·9 years (95% UI 86·7-87·2), and for men in Singapore, at 81·3 years (78·8-83·7) in 2016. Male life expectancy was generally lower than female life expectancy between 1970 and 2016, an

Healthcare Access and Quality Index based on mortality from causes amenable to personal health care in 195 countries and territories, 1990-2015 : a novel analysis from the Global Burden of Disease Study 2015

Background National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor estimates generated through the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to improve and expand the quantification of personal health-care access and quality for 195 countries and territories from 1990 to 2015. Methods We mapped the most widely used list of causes amenable to personal health care developed by Nolte and McKee to 32 GBD causes. We accounted for variations in cause of death certification and misclassifications through the extensive data standardisation processes and redistribution algorithms developed for GBD. To isolate the effects of personal health-care access and quality, we risk-standardised cause-specific mortality rates for each geography-year by removing the joint effects of local environmental and behavioural risks, and adding back the global levels of risk exposure as estimated for GBD 2015. We employed principal component analysis to create a single, interpretable summary measure-the Healthcare Quality and Access (HAQ) Index-on a scale of 0 to 100. The HAQ Index showed strong convergence validity as compared with other health-system indicators, including health expenditure per capita (r= 0.88), an index of 11 universal health coverage interventions (r= 0.83), and human resources for health per 1000 (r= 0.77). We used free disposal hull analysis with bootstrapping to produce a frontier based on the relationship between the HAQ Index and the Socio-demographic Index (SDI), a measure of overall development consisting of income per capita, average years of education, and total fertility rates. This frontier allowed us to better quantify the maximum levels of personal health-care access and quality achieved across the development spectrum, and pinpoint geographies where gaps between observed and potential levels have narrowed or widened over time. Findings Between 1990 and 2015, nearly all countries and territories saw their HAQ Index values improve; nonetheless, the difference between the highest and lowest observed HAQ Index was larger in 2015 than in 1990, ranging from 28.6 to 94.6. Of 195 geographies, 167 had statistically significant increases in HAQ Index levels since 1990, with South Korea, Turkey, Peru, China, and the Maldives recording among the largest gains by 2015. Performance on the HAQ Index and individual causes showed distinct patterns by region and level of development, yet substantial heterogeneities emerged for several causes, including cancers in highest-SDI countries; chronic kidney disease, diabetes, diarrhoeal diseases, and lower respiratory infections among middle-SDI countries; and measles and tetanus among lowest-SDI countries. While the global HAQ Index average rose from 40.7 (95% uncertainty interval, 39.0-42.8) in 1990 to 53.7 (52.2-55.4) in 2015, far less progress occurred in narrowing the gap between observed HAQ Index values and maximum levels achieved; at the global level, the difference between the observed and frontier HAQ Index only decreased from 21.2 in 1990 to 20.1 in 2015. If every country and territory had achieved the highest observed HAQ Index by their corresponding level of SDI, the global average would have been 73.8 in 2015. Several countries, particularly in eastern and western sub-Saharan Africa, reached HAQ Index values similar to or beyond their development levels, whereas others, namely in southern sub-Saharan Africa, the Middle East, and south Asia, lagged behind what geographies of similar development attained between 1990 and 2015. Interpretation This novel extension of the GBD Study shows the untapped potential for personal health-care access and quality improvement across the development spectrum. Amid substantive advances in personal health care at the national level, heterogeneous patterns for individual causes in given countries or territories suggest that few places have consistently achieved optimal health-care access and quality across health-system functions and therapeutic areas. This is especially evident in middle-SDI countries, many of which have recently undergone or are currently experiencing epidemiological transitions. The HAQ Index, if paired with other measures of health-systemcharacteristics such as intervention coverage, could provide a robust avenue for tracking progress on universal health coverage and identifying local priorities for strengthening personal health-care quality and access throughout the world.
