Intravenous iron sucrose for treatment of anemia in gynecology patients awaiting surgery

Background: Anemia refers to reduction in the total circulatory erythrocyte mass which results in decrease in the oxygen carrying capacity of the blood. Patients who require a surgical intervention as regards their complaints are many a times denied fitness because of anemia. Current anesthetic and surgical practice ideally recommend a hemoglobin level of > 10 g/dl or a hematocrit of >30 % for any surgical intervention. Surgery is postponed until cause of anemia is identified and the anemia corrected without resorting to blood transfusions. The current study evaluates other alternatives to increase the hemoglobin as early as possible without resorting to blood transfusion. The efficacy and safety of intravenous iron sucrose along with   the achievement of the desired hemoglobin values for patients posted for elective gynecological surgeries within the next menstrual cycle was evaluated.Methods: This study was an open label, single arm, and prospective study of women with iron deficiency anemia in gynecological disorders. 100 patients attending Gynecology OPD of Seth G. S. Medical College and KEM Hospital, Parel, Mumbai, Maharashtra, India requiring surgical intervention but not given fitness due to anaemia were the subjects of this study. All patients with surgically treatable conditions with hemoglobin level >7g/dL but < 10 g/dl were the inclusion criteria Selected subjects received intravenous iron sucrose. Maximum dose 200mg/weekX3 weeks initially. At the end of three weeks of starting therapy Hb estimation was done and compared with the baseline levels as regarding the hemoglobin rise. The results were statistically analyzed using the “paired t” test.Results: The requirement of iron-sucrose for the individual patient was calculated based on the weight of the patient. The analysis of iron requirement-sucrose combination showed a mean of 481.7 mg with standard deviation (SD) of 62.72 mg and a range of 378.85 mg. The minimum iron-sucrose requirement was 361.55 mg and the maximum was 740.40 mg The mean Hb (gm%) value before intervention was 8.43 with a standard deviation of 0.56, whereas, the mean Hb (gm %) value after intervention was higher, 10.41 with standard deviation (SD) of .56 the mean Hb (gm %) Increase in 2 weeks was 1.60 with standard deviation (SD) of 0.31, whereas, in 3 weeks was 2.03 with standard deviation (SD) of 0.51. The mean Hb (gm %) increase was higher in participants with 3 weeks, which was statistically significant (p<0.05).Conclusions: Parenteral iron therapy was not safe in the past but iron sucrose has made it the safest and effective therapy. Parenteral iron therapy can be used for patients with Hb level between 6-8mg/dl It is highly efficacious and reliable way to achieve the desired Hb level patient compliance is assured with intravenous iron sucrose patient can be satisfactorily posted for surgery within a period of 3 weeks i.e. within her next menstrual period by reliably and effectively correcting her anemia with intravenous iron sucrose

Conservative management options for morbidly adherent placenta

Background: Morbidly adherent placenta is still a very significant cause of obstetric hemorrhage.Methods: A retrospective, descriptive study was undertaken over a period of one and a half year in a tertiary care hospital of all diagnosed cases of morbidly adherent placenta which were managed conservatively and the maternal and perinatal outcomes were noted. Preparation for conservative management of cases of adherent placenta in the antenatal period included informing interventional radiologists and placement of internal iliac balloon catheters just before classical caesarean section. Post-operative methotrexate was used in a few patients.Results: 11 cases of morbidly adherent placenta diagnosed on Doppler ultrasound scan, and confirmed by MRI were identified. All patients underwent classical caesarean section. 9 patients had internal iliac balloon placement. 5 patients received methotrexate. 3 patients required obstetric hysterectomy. 1 maternal and 2 perinatal mortalities were noted.Conclusions: Interventional radiology and methotrexate can be used to avoid peripartum hysterectomy and to optimize maternal and perinatal outcome

An observational study to assess feto-maternal outcome in severely ill COVID-19 positive pregnant females admitted at dedicated COVID care center of southern Rajasthan

Background: COVID-19 infection is caused by corona virus SARS-COV2. the aim of the study is to assess feto-maternal outcome in severely ill covid positive pregnant females.Methods: An observational study was conducted at dedicated covid care center, RNT medical college Udaipur from Jan 2021 to May 2021 among pregnant females. In this study out of 236 total covid positive pregnant patients, 54 patients which could not maintain oxygen saturation, according to NIH criteria were included in our study.Results: Out of 54 pregnant women, 24 women delivered with 2 twin pregnancies. Out of this 67% underwent cesarean section and 33% were delivered by vaginal route. Postpartum hemorrhage seen in 29% of patients. Maternal death reported in 39% of patients. Out of 54 patients 38 patients were admitted in ICU. Invasive ventilation received by 26% of patients while oxygen received by non-invasive ventilation (15%), Bains (18%) rest by NRBM and venturi mask (41%). Remdesivir were given in 26 (48%) patients.Conclusions: Our study suggests there may be increased risk of adverse pregnancy outcome for mother and fetus. COVID-19 in pregnancy was associated with risks of pre-eclampsia, stillbirth, preterm birth, PPH. Similar to general population comorbidities do play a role in the outcome of disease in pregnancy. Further studies are needed for effective strategies to prevent adverse outcomes in pregnant females with COVID-19.

Quantitative estimation of serum 25(OH) D and associated risk factors of vitamin D deficiency among pregnant women attending a tertiary care hospital in Udaipur, Rajasthan

Introduction: Insufficiency of vitamin D is now known globally and is exceptionally common in temperate and tropical countries. Due to its several negative maternal and fetal health consequences, vitamin D insufficiency in pregnancy is a growing concern worldwide. Methods: A cross-sectional study was conducted at a tertiary medical hospital for one year. A sample of 280 pregnant women attending antenatal clinic (ANC) were enrolled using a random sampling technique. A standard questionnaire was designed to collect socio-demographic details and the sun exposure of participants. To analyse dietary habits and consumption of vitamin D-rich foods, a food frequency questionnaire (FFQ) was used. Serum samples were obtained and analyzed for and calcium levels. Results: High prevalence of maternal vitamin D insufficiency 122 (43.57%) and deficiency 92 (32.85%) observed. Most 263 (94%) participants had adequate serum calcium levels (> 8.5 mg/dL). Younger participants (< 25 yrs.) had low mean vitamin D (17.61±13.89 ng/mL), adequate calcium (9.52±0.70 mg/dL) levels. Rural residence, multigravida, advanced trimester, poor education, joint family, unemployment, and lower socioeconomic status were found associated with vitamin D insufficiency. Conclusion: In the present study a high prevalence of maternal vitamin D deficiency was observed. The burden of Vitamin D inadequacy (76.39%) reflects poor nutritional status and health risks for mothers and fetuses. Sociodemographic factors (Residence, Education, Family, and Socioeconomic status) were linked to this micronutrient deficiency. There is a need for further community-based nutritional research on sociodemographic, biological, and nutritional determinants for in-depth understanding

Molecular Sequence of Events and Signaling Pathways in Cerebral Metastases

Brain metastases are the leading cause of morbidity and mortality among cancer patients, and are reported to occur in about 40% of cancer patients with metastatic disease in the United States of America. Primary tumor cells appear to detach from the parent tumor site, migrate, survive and pass through the blood brain barrier in order to establish cerebral metastases. This complex process involves distinct molecular and genetic mechanisms that mediate metastasis from these primary organs to the brain. Furthermore, an interaction between the invading cells and cerebral milieu is shown to promote this process as well. Here, we review the mechanisms by which primary cancer cells metastasize to the brain via a mechanism called epithelial-to-mesenchymal transition, as well as the involvement of certain microRNA and genetic aberrations implicated in cerebral metastases from the lung, breast, skin, kidney and colon. While the mechanisms governing the development of brain metastases remain a major hindrance in treatment, understanding and identification of the aforementioned molecular pathways may allow for improved management and discovery of novel therapeutic targets

Modelling the impact and cost-effectiveness of the HIV intervention programme amongst commercial sex workers in Ahmedabad, Gujarat, India.

BACKGROUND: Ahmedabad is an industrial city in Gujarat, India. In 2003, the HIV prevalence among commercial sex workers (CSWs) in Ahmedabad reached 13.0%. In response, the Jyoti Sangh HIV prevention programme for CSWs was initiated, which involves outreach, peer education, condom distribution, and free STD clinics. Two surveys were performed among CSWs in 1999 and 2003. This study estimates the cost-effectiveness of the Jyoti Sangh HIV prevention programme. METHODS: A dynamic mathematical model was used with survey and intervention-specific data from Ahmedabad to estimate the HIV impact of the Jyoti Sangh project for the 51 months between the two CSW surveys. Uncertainty analysis was used to obtain different model fits to the HIV/STI epidemiological data, producing a range for the HIV impact of the project. Financial and economic costs of the intervention were estimated from the providers perspective for the same time period. The cost per HIV-infection averted was estimated. RESULTS: Over 51 months, projections suggest that the intervention averted 624 and 5,131 HIV cases among the CSWs and their clients, respectively. This equates to a 54% and 51% decrease in the HIV infections that would have occurred among the CSWs and clients without the intervention. In the absence of intervention, the model predicts that the HIV prevalence amongst the CSWs in 2003 would have been 26%, almost twice that with the intervention. Cost per HIV infection averted, excluding and including peer educator economic costs, was USD 59 and USD 98 respectively. CONCLUSION: This study demonstrated that targeted CSW interventions in India can be cost-effective, and highlights the importance of replicating this effort in other similar settings.Published versio

Global, regional, and national burden of disorders affecting the nervous system, 1990–2021: a systematic analysis for the Global Burden of Disease Study 2021

Background Disorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not include neurodevelopmental disorders, as defined by the International Classification of Diseases (ICD)-11, or a subset of cases of congenital, neonatal, and infectious conditions that cause neurological damage. Here, we estimate nervous system health loss caused by 37 unique conditions and their associated risk factors globally, regionally, and nationally from 1990 to 2021. Methods We estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs), with corresponding 95% uncertainty intervals (UIs), by age and sex in 204 countries and territories, from 1990 to 2021. We included morbidity and deaths due to neurological conditions, for which health loss is directly due to damage to the CNS or peripheral nervous system. We also isolated neurological health loss from conditions for which nervous system morbidity is a consequence, but not the primary feature, including a subset of congenital conditions (ie, chromosomal anomalies and congenital birth defects), neonatal conditions (ie, jaundice, preterm birth, and sepsis), infectious diseases (ie, COVID-19, cystic echinococcosis, malaria, syphilis, and Zika virus disease), and diabetic neuropathy. By conducting a sequela-level analysis of the health outcomes for these conditions, only cases where nervous system damage occurred were included, and YLDs were recalculated to isolate the non-fatal burden directly attributable to nervous system health loss. A comorbidity correction was used to calculate total prevalence of all conditions that affect the nervous system combined. Findings Globally, the 37 conditions affecting the nervous system were collectively ranked as the leading group cause of DALYs in 2021 (443 million, 95% UI 378–521), affecting 3·40 billion (3·20–3·62) individuals (43·1%, 40·5–45·9 of the global population); global DALY counts attributed to these conditions increased by 18·2% (8·7–26·7) between 1990 and 2021. Age-standardised rates of deaths per 100 000 people attributed to these conditions decreased from 1990 to 2021 by 33·6% (27·6–38·8), and age-standardised rates of DALYs attributed to these conditions decreased by 27·0% (21·5–32·4). Age-standardised prevalence was almost stable, with a change of 1·5% (0·7–2·4). The ten conditions with the highest age-standardised DALYs in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer's disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications due to preterm birth, autism spectrum disorder, and nervous system cancer. Interpretation As the leading cause of overall disease burden in the world, with increasing global DALY counts, effective prevention, treatment, and rehabilitation strategies for disorders affecting the nervous system are needed.

Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950–2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021

Background Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020–21 COVID-19 pandemic period. Methods 22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. Findings Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5–65·1] decline), and increased during the COVID-19 pandemic period (2020–21; 5·1% [0·9–9·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4·66 million (3·98–5·50) global deaths in children younger than 5 years in 2021 compared with 5·21 million (4·50–6·01) in 2019. An estimated 131 million (126–137) people died globally from all causes in 2020 and 2021 combined, of which 15·9 million (14·7–17·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22·7 years (20·8–24·8), from 49·0 years (46·7–51·3) to 71·7 years (70·9–72·5). Global life expectancy at birth declined by 1·6 years (1·0–2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7·89 billion (7·67–8·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39·5% [28·4–52·7]) and south Asia (26·3% [9·0–44·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92·2%) of 204 nations. Interpretation Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic
