Massive hemoperitoneum in case of large subserosal fibroid- a rare case report

Rupture of veins on the surface of uterine leiomyoma is an extremely uncommon gynaecological cause of haemoperitoneum. It is a life-threating emergency. In most cases, bleeding is a result of trauma or torsion. Here we report a case of massive intraperitoneal haemorrhage due to rupture of vessels on the surface of large sub-serous leiomyoma to stress on the fact that a differential diagnosis of rupture of surface vessels in a fibroid should be considered while dealing with a case of haemoperitoneum with pelvic masse

Tobacco use among 1,310,716 women of reproductive age (15-49 years) in 42 low- and middle-income countries : secondary data analysis from the 2010-2016 Demographic and Health Surveys

INTRODUCTION: Tobacco use among women, especially during pregnancy is a public health concern. There is a need to understand the diverse nature of their tobacco consumption across the globe. METHODS: We used Demographic and Health Surveys (DHS) data collected between 2010 and 2016 from 42 low- and middle-income countries (LMICs) to estimate the prevalence of smoking, smokeless tobacco, and dual use among pregnant and non-pregnant women of reproductive age (15–49 y). We compared tobacco use between both groups adjusted for age, type of residence, education and combined wealth index, and a subgroup analysis for the South-East Asia Region (SEAR) as the tobacco use in SEAR among women is far more diverse than in other regions primarily due to the popularity of smokeless tobacco use in this region. RESULTS: Based on the data of 1 310 716 women in 42 LMICs, the prevalence of smoking was 0.69%(95%CI: 0.51–0.90) among pregnant women and 1.09%(95%CI: 0.81–1.42) among non-pregnant women. The prevalence of smokeless tobacco use was 0.56%(95%CI: 0.33–0.84) among pregnant women and 0.78%(95%CI: 0.35–1.37) among non-pregnant women. The relative risk ratios(RRR) for smoking (0.85; 95%CI: 0.67–1.09) and smokeless tobacco use (0.81; 95%CI:0.67–1.00) were not-significantly lower among pregnant women than non-pregnant women and education and wealth index had an inverse relationship with both forms of tobacco. In SEAR, among pregnant women, the prevalence of smoking and smokeless tobacco use was 1.81% and 0.45%, respectively. However, pregnant women were 7%(RRR 1.07; 95%CI:1.02–1.12) more likely to use smokeless tobacco than non-pregnant women. CONCLUSION: Despite the added risk of foetal harm during pregnancy, there is no evidence that the tobacco consumption between pregnant and non-pregnant women differ in 42 LMICs. A significantly higher use of smokeless tobacco among pregnant women in SEAR is of particular concern and warrants further investigation. IMPLICATIONS: Tobacco use among women in low- and middle-income countries (LMICs) is lower than high-income countries (HICs), but this may be because LMICs are earlier in the epidemiological transition of tobacco use. If ignored as a public health issue and the tobacco industry continues to market its products to women, the level of tobacco use may rise as it did in HICs. Also, despite low prevalence rates and with no evidence that these differ among pregnant and non-pregnant women, is concerning as tobacco consumption in any form during pregnancy is associated with poor birth outcomes. This suggests a need for raising awareness about the harms of tobacco use among women in LMICs, especially during pregnancy. There is a need to develop preventive and cessation interventions to decrease tobacco use (smoking and smokeless) among women who are from low socio-economic status and less educated, as they bear the greatest burden of tobacco use

Hypothermia for moderate or severe neonatal encephalopathy in low-income and middle-income countries (HELIX): a randomised controlled trial in India, Sri Lanka, and Bangladesh

Background: Although therapeutic hypothermia reduces death or disability after neonatal encephalopathy in high-income countries, its safety and efficacy in low-income and middle-income countries is unclear. We aimed to examine whether therapeutic hypothermia alongside optimal supportive intensive care reduces death or moderate or severe disability after neonatal encephalopathy in south Asia. Methods: We did a multicountry open-label, randomised controlled trial in seven tertiary neonatal intensive care units in India, Sri Lanka, and Bangladesh. We enrolled infants born at or after 36 weeks of gestation with moderate or severe neonatal encephalopathy and a need for continued resuscitation at 5 min of age or an Apgar score of less than 6 at 5 min of age (for babies born in a hospital), or both, or an absence of crying by 5 min of age (for babies born at home). Using a web-based randomisation system, we allocated infants into a group receiving whole body hypothermia (33·5°C) for 72 h using a servo-controlled cooling device, or to usual care (control group), within 6 h of birth. All recruiting sites had facilities for invasive ventilation, cardiovascular support, and access to 3 Tesla MRI scanners and spectroscopy. Masking of the intervention was not possible, but those involved in the magnetic resonance biomarker analysis and neurodevelopmental outcome assessments were masked to the allocation. The primary outcome was a combined endpoint of death or moderate or severe disability at 18–22 months, assessed by the Bayley Scales of Infant and Toddler Development (third edition) and a detailed neurological examination. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT02387385. Findings: We screened 2296 infants between Aug 15, 2015, and Feb 15, 2019, of whom 576 infants were eligible for inclusion. After exclusions, we recruited 408 eligible infants and we assigned 202 to the hypothermia group and 206 to the control group. Primary outcome data were available for 195 (97%) of the 202 infants in the hypothermia group and 199 (97%) of the 206 control group infants. 98 (50%) infants in the hypothermia group and 94 (47%) infants in the control group died or had a moderate or severe disability (risk ratio 1·06; 95% CI 0·87–1·30; p=0·55). 84 infants (42%) in the hypothermia group and 63 (31%; p=0·022) infants in the control group died, of whom 72 (36%) and 49 (24%; p=0·0087) died during neonatal hospitalisation. Five serious adverse events were reported: three in the hypothermia group (one hospital readmission relating to pneumonia, one septic arthritis, and one suspected venous thrombosis), and two in the control group (one related to desaturations during MRI and other because of endotracheal tube displacement during transport for MRI). No adverse events were considered causally related to the study intervention. Interpretation: Therapeutic hypothermia did not reduce the combined outcome of death or disability at 18 months after neonatal encephalopathy in low-income and middle-income countries, but significantly increased death alone. Therapeutic hypothermia should not be offered as treatment for neonatal encephalopathy in low-income and middle-income countries, even when tertiary neonatal intensive care facilities are available.

Host-HIV-1 Interactome: A Quest for Novel Therapeutic Intervention

The complex nature and structure of the human immunodeficiency virus has rendered the cure for HIV infections elusive. The advances in antiretroviral treatment regimes and the development of highly advanced anti-retroviral therapy, which primarily targets the HIV enzymes, have dramatically changed the face of the HIV epidemic worldwide. Despite this remarkable progress, patients treated with these drugs often witness inadequate efficacy, compound toxicity and non-HIV complications. Considering the limited inventory of druggable HIV proteins and their susceptibility to develop drug resistance, recent attempts are focussed on targeting HIV-host interactomes that are essential for viral reproduction. Noticeably, unlike other viruses, HIV subverts the host nuclear pore complex to enter into and exit through the nucleus. Emerging evidence suggests a crucial role of interactions between HIV-1 proteins and host nucleoporins that underlie the import of the pre-integration complex into the nucleus and export of viral RNAs into the cytoplasm during viral replication. Nevertheless, the interaction of HIV-1 with nucleoporins has been poorly described and the role of nucleoporins during nucleocytoplasmic transport of HIV-1 still remains unclear. In this review, we highlight the advances and challenges in developing a more effective antiviral arsenal by exploring critical host-HIV interactions with a special focus on nuclear pore complex (NPC) and nucleoporins

Disparity Dependent Segmentation Based Stereo Image Coding

In this paper, we propose a novel rate-distortion (R-D) optimized disparity based coding scheme for stereo images. This new scheme efficiently integrates the coding of the disparity field with the residual image obtained via disparity estimation/compensation (DE/DC) in an R-D framework. The scheme first performs a quadtree decomposition of the target image and computes the disparity information along with the residual image for each node in the tree. An R-D based algorithm is then used for optimum bit allocation among the different quadtree nodes. The proposed scheme further jointly encodes the neighboring nodes with similar disparity information to attain higher coding gains. We present simulation results for the proposed scheme and compare these results with the performance of a fixed block size DE/DC based JPEG2000 stereo image coder. Our simulations show that the proposed scheme outperforms the fixed block size based disparity compensated JPEG2000 coder by more than 0.5 dB

Prevalence of Postmenopausal Symptoms, Its Effect on Quality of Life and Coping in Rural Couple

Aim: Menopause is a physiological process, with potential to lead to various pathological/psychological complications, leading to change in quality of life (QOL). Although literature suggests the effect of menopause on various aspects of life, there is scarcity of studies from rural setup in this regard. Thus, it is essential to assess extent of menopause-related changes, its awareness, and coping mechanisms in rural couple. This study aimed to find the prevalence of postmenopausal symptoms, its severity, and effect on QOL of rural women and the couples' coping mechanisms. Materials and Methodology: A cross-sectional survey was conducted by approaching 250 families from two villages of Gujarat, India. Inclusion criteria were any woman having attained menopause naturally within last 10 years and having her husband available for data collection. Hundred such couples consenting for participation were included in the study. Data on demographic variables, menopause-specific QOL, personal health of women, and coping of the couple were collected. Results: The prevalence of menopausal symptoms was found to be 47%. Mean (standard deviation) age at menopause was 44.9 (4.9) years. The prevalence of at least one symptom related to vasomotor was 21.3%, physical 91.5%, psychosocial 44.7%, and sexual was 0%. “QOL and Bother” analysis revealed that all those with menopausal symptoms also had their QOL affected from mild-to-moderate extent. The husbands of women with menopausal symptoms were aware of their condition; however, neither of them exhibited use of the active coping mechanism. The avoidant emotional coping strategy appeared to be followed by most. Conclusion: Couples were found to be aware of menopause; however, the symptoms arising as consequence of it seem to be accepted as natural age-related changes. This could possibly account for not taking any active coping strategy despite reporting of mild-to-moderate botheration by women and awareness in both. Rigorous health education and awareness about menopausal changes might be beneficial
