A study on prevalence of anemia in pregnancy in South India
Background: Anemia in pregnancy is a major health problem worldwide, especially in developing countries like India. Maternal and fetal outcomes are poor in pregnant patients with anemia. The most important cause of anemia is iron deficiency anemia which can be prevented by early oral iron supplementation.Methods: This cross-sectional study was conducted in the department of obstetrics and gynecology of our tertiary care teaching institution for a period of one year. 1290 pregnant women coming to the antenatal OPD were screened for anemia and 490 women. Patients who were not anemic were excluded. 800 patients were enrolled in the study. Each patient was interviewed using a structured interview schedule and the data obtained was analyzed.Results: The percentage of anemia in pregnant women was 62% in our study of which 40% were mildly anemic, 55% were moderately anemic and 5% were severely anemic. Maximum number of anemic women -mild, moderate and severe was seen in the age group 20-24 years. Mild and severe anemia was seen more in the secondary educated women. Maximum percentage of anemia was seen in the lower socio-economic status followed by middle and was lowest in the higher socio-economic status group. Prevalence of anemia was almost equal in primigravida and multigravidas (around 50%) but 80% of severely anemic patients were multigravida. Almost 68% took iron and folic acid tablets regularly.Conclusions: Treating anemia in pregnant women will go a long way in improving maternal and fetal outcome. Hence a future healthy younger generation can be produced. Iron tablets can be distributed at school to young girls to prevent anemia in future women
Clinical pattern and presentation of abnormal uterine bleeding
Background: Abnormal uterine bleeding (AUB) is a very common debilitating gynecological condition among women of the reproductive age group. This diagnosis is given to women in whom no clear etiology is identified. It can occur in ovulatory and anovulatory cycle. It influences the physical, emotional, sexual and professional life of a woman. This study was carried out to evaluate the clinical profile of abnormal uterine bleeding.Methods: This cross-sectional study was carried out among 350 patients who were clinically diagnosed with AUB for a period of one year from April 2018 to March 2019. Patients with uterine polyp, adenomyosis, Leiomyoma, malignancies and with various coagulopathies were excluded from the study by physical examination, ultrasound, histopathology and blood test. The remaining 280 patients between the ages 20-60 years were selected for clinical classification of AUB.Results: Majority of the participants were in the age group of 41-50 years (60%). AUB is most commonly seen in multiparous women (48.92%). The prominent bleeding pattern seen was menorrhagia (52.2%).Conclusions: Menorrhagia is the most common form of AUB and there is a need to prevent the consequences of menorrhagia by way of creating awareness among the women, and by early diagnosis and clinical management of complications
MICROORGANISMS VARIANTS FOR HEALTHCARE-ASSOCIATED INFECTIONS IN A SELECTED TERTIARY CARE HOSPITAL
Objective: Microorganisms are minute and can be only in microscope and these are not visible to naked eyes. Various types of microbe include bacteria, virus, fungi, and protozoa. These microorganisms are subclassified and these are disease causing leading to mortality and morbidity. Healthcare-associated infections (HAIs) arise from different variants of microbes and knowing the category of microbes for treating the diseases with specific antibiotics is important for better patient outcome.
Methods: Using secondary data, all the patients who had HAI for 3 years were taken into consideration by considering the different variants of microorganisms.
Results: Retrospective data collected for the period of 3 years the inpatients who got admitted for more than 48 h of duration, the data collected included the parameters for various microorganisms such as Bacilli, cocci, Klebsiella, Acinetobacter, and Aures, other micro-organisms such as Escherichia coli, Citrobacter, and Pseudomonas microorganisms. Bacilli group of microorganisms was more common for urinary tract infection, blood stream infection, and ventilator-associated pneumonia. Aures was more common among surgical site infection infections.
Conclusions: Most of the patients who had an HAI had two or more different kind of microorganisms which are responsible for spreading infection. There is a need to control microbial flora in the hospital set up as the rate of HAI increases with microbial flora
Electrooptic soft mode response of compounds exhibiting the antiferroelectric phase
We report measurements on the electrooptic response of thin samples (~2-5 μm) of two antiferroelectric liquid crystals. All the phase transitions in these compounds can be very easily detected using this technique. We have been able to measure such an electrooptic effect for the first time in the antiferroelectric and smectic I∗ phases of a tolane compound. The response shows a relaxation at high frequencies (~10 KHz) and is at-tributed to a soft mode which produces an asymmetry in the molecular tilt in successive layers
Time Domain Signal Detection for MIMO OFDM
The MIMO techniques with OFDM is regarded as a promising solution for increasing data rates, for wireless access qualities of future wireless local area networks, fourth generation wireless communication systems, and for high capacity, as well as better performance. Hence as part of continued research, in this paper an attempt is made to carry out modelling, analysis, channel matrix estimation, synchronization and simulation of MIMO-OFDM system. A time domain signal detection algorithm can be based on Second Order Statistics (SOS) proposed for MIMO-OFDM system over frequency selective fading channels. In this algorithm, an equalizer is first inserted to reduce the MIMO channels to ones with channel length shorter than or equal to the Cyclic Prefix (CP) length. A system model in which the ith received OFDM block left shifted by j samples introduced. MIMO OFDM system model which uses the equalizer can be designed using SOS of the received signal vector to cancel the most of the Inter Symbol Interference (ISI). The transmitted signals are then detected from the equalizer output. In the proposed algorithm, only 2P (P transmitted antennas / users in the MIMO-OFDM system) columns of the channel matrix need to be estimated and channel length estimation is unnecessary, which is an advantage over an existing algorithms. In addition, the proposed algorithm is applicable for irrespective of whether the channel length is shorter than, equal to or longer than the CP length. Simulation results verify the effectiveness of the proposed algorithm and shows that it out performs the existing one in all cases
Crptography based Lifi for Patient Privacy and Emergency Health Service Using IOT
Medical care is one such region, where WIFI is as yet not utilized as the electromagnetic waves influences patients with sicknesses like neurological problems, diseases and so forth. Accordingly, LIFI can be respected the following large thing, as it represents no gamble to patients and offers more advantages than WIFI, such as faster speeds and a larger spectrum. The only issue that hospitals have while exchanging data through it is ensuring confidentiality. The methodology proposed here leverages Secure Hash Algorithms to give maximum security as a solution to this challenge. The Secure Hash Algorithm is a bonus feature that is mostly utilised for authentication. IoT connects physical devices such as sensors and actuators to networks. The programming routines can be visualised from any location thanks to cloud storage. These algorithms can be employed in a variety of applications, including smart homes, digital technologies, and banking systems. This research presents a model that takes into account a human's heart rate, glucose level, and temperature. In the even to fan emergency, adjacent hospitals are alerted to the patient's condition, allowing them to provide timely and correct care. This will save you from having to go to the hospital. Temperature, blood pressure, heart rate, gas sensor, and fall detection are among the vital signs monitored by the system. An Arduino controller and a GSM900Amodule make up the system design. The monitored values can be supplied via mobile phones, and if an abnormal state is detected, the buzzer is activated, and the information is communicated to the concerned members via the mobile app
Integrating systems biology models and biomedical ontologies
BACKGROUND: Systems biology is an approach to biology that emphasizes the structure and dynamic behavior of biological systems and the interactions that occur within them. To succeed, systems biology crucially depends on the accessibility and integration of data across domains and levels of granularity. Biomedical ontologies were developed to facilitate such an integration of data and are often used to annotate biosimulation models in systems biology. RESULTS: We provide a framework to integrate representations of in silico systems biology with those of in vivo biology as described by biomedical ontologies and demonstrate this framework using the Systems Biology Markup Language. We developed the SBML Harvester software that automatically converts annotated SBML models into OWL and we apply our software to those biosimulation models that are contained in the BioModels Database. We utilize the resulting knowledge base for complex biological queries that can bridge levels of granularity, verify models based on the biological phenomenon they represent and provide a means to establish a basic qualitative layer on which to express the semantics of biosimulation models. CONCLUSIONS: We establish an information flow between biomedical ontologies and biosimulation models and we demonstrate that the integration of annotated biosimulation models and biomedical ontologies enables the verification of models as well as expressive queries. Establishing a bi-directional information flow between systems biology and biomedical ontologies has the potential to enable large-scale analyses of biological systems that span levels of granularity from molecules to organisms
Urine levels of rifampicin & isoniazid in asymptomatic HIV-positive individuals
Background & objectives: AIDS and its associated gastrointestinal complications may impair the absorption
of anti-tuberculosis (TB) drugs. Impaired absorption of anti-TB drugs could lead to low drug exposure,
which might contribute to acquired drug resistance and reduced effectiveness of anti-TB treatment. The
aim of this study was to obtain information on the status of absorption of rifampicin (RMP) and isoniazid
(INH) in asymptomatic HIV- positive individuals, who are less immunocompromised. The D-xylose
absorption test was also carried out to assess the absorptive capacity of intestive.
Methods: The absorption of RMP, INH and D-xylose was studied in 15 asymptomatic HIV- positive
individuals with CD4 cell counts > 350 cells/mm3 and 16 healthy volunteers, after oral administration of
single doses of RMP (450 mg), INH (300 mg) and D-xylose (5 g). Urine was collected up to 8 h after drug
administration. Percentage dose of the drugs and their metabolites and D-xylose excreted in urine were
calculated.
Results: A significant reduction in the urinary excretion of INH and D-xylose in HIV-positive persons
compared to healthy volunteers was observed. The per cent dose of RMP and its metabolite, desacetyl
RMP was also lower in HIV-positive persons compared to healthy volunteers, but this difference was not
statistically significant.
Interpretation & conclusion: Decreased urinary excretion of D-xylose and INH are suggestive of intestinal
malabsorption in HIV-positive individuals. HIV infection could cause malabsorption of anti-TB drugs
even at an early stage of the disease. The clinical implications of these findings need to be confirmed in
larger studies
Opposite ends of the same stick? Multi-method test of the dimensionality of individualism and collectivism
Cataloged from PDF version of article.The construct of individualism–collectivism (IND-COL) has become the definitive standard in
cross-cultural psychology, management, and related fields. It is also among the most controversial,
in particular, with regard to the ambiguity of its dimensionality: Some view IND and COL as the opposites of a single continuum, whereas others argue that the two are independent constructs.
We explored the issue through seven different tests using original individual-level data from 50
studies and meta-analytic data from 149 empirical publications yielding a total of 295 samplelevel
observations that were collected using six established instruments for assessing IND and
COL as separate constructs. Results indicated that the dimensionality of IND-COL may depend
on (a) the specific instrument used to collect the data, (b) the sample characteristics and the
cultural region from which the data were collected, and (c) the level of analysis. We also review
inconsistencies, deficiencies, and challenges of conceptualizing IND-COL and provide guidelines
for developing and selecting instruments for measuring the construct, and for reporting and
meta-analyzing results from this line of research
