A rare case report of conjoined twins: Thoraco-omphalopagus with anterior abdominal wall defect
Conjoined twins are a rare deviation of monozygotic monoamniotic twins which results from fusion of the two at any part of their body. The prognosis is not good and associated with high mortality. Here we report a case of conjoined twin which was referred to our tertiary care hospital as twin pregnancy with impacted breech in obstructed labour. Taking mothers condition into account, she was taken for emergency caesarean section, performing which we realised that it was a conjoined twin. The baby were still born and conjoined at thorax and abdomen (thoraco-omphalopagus) with anterior abdominal wall defect in one and unrevealed sex in other. Current report emphasizes on making an early diagnosis of conjoined twin pregnancy, so that it can be managed at the earliest according to the gestational age
Effect of antenatal retroviral therapy on feto-maternal outcome in human immunodeficiency virus seropositive patients
Background: To study the effect of HIV and duration of ART on term of delivery, newborn birth weight and adverse fetal outcomes.Methods: Prospective comparative study of 40 HIV seropositive pregnant females with varying duration of ART (tenofovir 300 mg + lamivudine 300 mg + efavirenz 600 mg) and HIV seronegative pregnant females attending ANC and delivering in department of obstetrics and gynecology at S. M. S. Medical College, Jaipur, Rajasthan, India.Results: Most HIV seropositive patients were in age group 25 to 30 years and more number were booked in comparison to unbooked. Adverse fetal outcomes were seen more in HIV seropositive patients and they were found to be statistically significant (p=0.029). No relationship could be derived of duration of ART on either the birth weight or term of delivery or adverse fetal outcomes.Conclusions: Maternal HIV infection was significantly found associated with adverse fetal outcome and this was not affected by the use of ART
GR-100 - Non-Invasive Monitoring of Human Hygiene using Vibration Sensor and Classifiers
Abstract: Personal hygiene is how people take care of their bodies. Maintaining hygiene practice reduces the spread of illness and the risk of medical conditions. With the current pandemic situation, practices like washing hands and taking regular showers have taken major importance among people, especially for senior populations that live alone at home. Having an understanding of the human hygiene habits of our seniors is fundamental to monitoring health conditions.This research work presents the concept and idea of a noninvasive monitoring system for human hygiene using only vibration sensors. The approach is based on a geophone, a digitizer, and a cost-efficient computer board (raspberry pi). We capture the vibration of the water flow while people perform activities in the bathroom (open faucet, flush toilets) and kitchen (open kitchen sink). Results show that our approach can distinguish from these different activities with an accuracy higher than 90%. With this approach, we hope to start a new tendency of monitoring people activities without using cameras or other privacy-invasive methods.Department: Information TechnologySupervisor: Dr. Maria ValeroTopics: IoT/Cloud/Networkin
A case report of sirenomelia with two umbilical arteries: an unusual finding in a rare case
Sirenomelia also known as Mermaid syndrome is a rarely encountered fusion anomaly of the caudal region of body often associated with Potter’s facies, single umbilical artery and various visceral abnormalities which make it irreconcilable with life. Here we report a case of sirenomelia delivered in our tertiary care hospital by lower segment cesarean section to a 24 year old third gravida with no previous live issues. No high risk factors could be identified with the mother including diabetes mellitus. Baby was born alive with Potter’s facies. Both the lower limbs were merging into each other like a mermaid’s tail (hence called mermaid syndrome). Sex of the baby could not be identified and the urogenital and anal orifices were absent. Umbilical cord stump had two umbilical arteries. The baby died after 20 hours of life. There appears to be no definitive modality for diagnosing sirenomelia in the antenatal period. However, if a patient has consistently low AFI without any history of leaking per vaginum, high resolution USG or colour Doppler should be done at the earliest to look for the cause
Non-Invasive Monitoring of Human Hygiene using Vibration Sensor and Classifier
This paper presents a concept and an idea of a non-invasive monitoring system for human hygiene using vibration sensors. The approach is based on a combination of geophone sensor, a digitizer, and a cost-efficient computer board in a Raspberry Shake enclosure. People’s personal hygiene habits speak volume about how they take care of their bodies and health. Maintaining good hygiene practices not only reduce your chances of contracting a disease, but it could also reduce the risk of spreading illness within your community. Given the current pandemic, daily habits such as washing hands or taking regular showers have taken major importance among people, especially for our elderly population living alone at home or in an assisted living facility. Monitoring daily hygiene routine could truly help our healthcare professionals be proactive rather than reactive in identifying and controlling the spread of potential outbreaks within our community
The Influence of Natural Barriers in Shaping the Genetic Structure of Maharashtra Populations
BACKGROUND: The geographical position of Maharashtra state makes it rather essential to study the dispersal of modern humans in South Asia. Several hypotheses have been proposed to explain the cultural, linguistic and geographical affinity of the populations living in Maharashtra state with other South Asian populations. The genetic origin of populations living in this state is poorly understood and hitherto been described at low molecular resolution level. METHODOLOGY/PRINCIPAL FINDINGS: To address this issue, we have analyzed the mitochondrial DNA (mtDNA) of 185 individuals and NRY (non-recombining region of Y chromosome) of 98 individuals belonging to two major tribal populations of Maharashtra, and compared their molecular variations with that of 54 South Asian contemporary populations of adjacent states. Inter and intra population comparisons reveal that the maternal gene pool of Maharashtra state populations is composed of mainly South Asian haplogroups with traces of east and west Eurasian haplogroups, while the paternal haplogroups comprise the South Asian as well as signature of near eastern specific haplogroup J2a. CONCLUSIONS/SIGNIFICANCE: Our analysis suggests that Indian populations, including Maharashtra state, are largely derived from Paleolithic ancient settlers; however, a more recent (∼10 Ky older) detectable paternal gene flow from west Asia is well reflected in the present study. These findings reveal movement of populations to Maharashtra through the western coast rather than mainland where Western Ghats-Vindhya Mountains and Narmada-Tapti rivers might have acted as a natural barrier. Comparing the Maharastrian populations with other South Asian populations reveals that they have a closer affinity with the South Indian than with the Central Indian populations
Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world
Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.
Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.
Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.
Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.
Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two
Background
The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd.
Methods
We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background.
Results
First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001).
Conclusions
In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
