Background: According to global estimates for 2017, nearly 295,000 maternal deaths occurred worldwide. Thus, approximately 810 women die every day due to pregnancy-related complications. This burden of maternal deaths in LMICs is primarily due to poor healthcare service utilization, as indicated by relatively low rates of institutional deliveries and skilled-birth attendance (SBA). We conducted this study with an aim to assess the factors associated with home delivery and its subsequent effect on the pregnancy outcome in rural Sindh, Pakistan., Methods: Data for this study were taken from The Global Network's Maternal Newborn Health Registry (MNHR), which is a prospective, population-based observational cohort study. Registry data for 2018-2019 for District Thatta, Pakistan was retrieved for the analysis. Multivariable logistic regression models were used to determine the effect of each independent variable on the place of delivery by including all predictors and covariates. Results of the regression analyses are presented with crude odds ratios (OR) and adjusted odds ratios (aOR) with 95% confidence intervals (CIs)., Results: A total of 4649 women were included in the study, of these, 1286 (27.7%) women had delivered at home. Of those who delivered at home, a larger proportion was illiterate (90%), had a BMI of less than 18.5 kg/m 2 (26.0%), had parity of 3 or more (48.1%), and had a history of pregnancy loss as compared to women who had institutional delivery. In addition, two-thirds of women (63.4%) who had delivered at home had less than 4 ANC visits, whereas 15.6% did not receive any ANC. On multivariable logistic regression we found that home delivery was significantly associated with being illiterate (aOR = 1.60; [95% CI: 1.34, 2.04]), having high parity (aOR = 1.91; [95% CI: 1.58, 2.32]), and no ANC visit (aOR = 14.8; [95% CI: 10.2, 21.5])., Conclusions: More than a quarter of our study sample women delivered at home. These women were illiterate, multiparous, and did not receive antenatal care during pregnancy. It is essential to conduct extensive educational interventions for the women and their family members regarding the potential benefits of delivering in a safe and skilled environment. Moreover, the provision of comprehensive and quality antenatal care should be ensured as it improves the mothers' health-seeking behavior and helps them make informed decisions about their health and well-being., (© 2022.

Cadmium is a potent neurotoxin and induces adverse impact on brain function. Protective effects of monoterpenes on the CNS have been reported previously. The present study was designed to investigate the beneficial effect of thymol on cadmium-induced neurotoxicity. Rats were initially divided into 2 groups, vehicle control and thymol. Thymol (40mg/kg) was given orally for 14 days. Each group was subdivided into two groups (Vehicle control and Cadmium, Thymol and Thymol+Cadmium). Cadmium Chloride (5mg/kg) was given for last 3 days only to the groups assigned as Cadmium and Thymol+Cadmium. Behavioral parameters were assessed after 24h of last dose of cadmium. Brain sample were collected and BDNF was measured in hippocampus. The present study suggests that pre-administration of thymol provides a protective therapy against cadmium-induced intoxication by enhancing the brain BDNF levels and plasticity. Results further suggest that thymol not only ameliorates cadmium-induced learning and memory impairment but also reduced anxiety, motor incoordination and depression assessed by various behavioral tests. The study may provide a better apprehension of the neuroprotective role of thymol and highlighting its significance in the diet for human health particularly in cadmium intoxication.

Background: 40-60% of people with HIV report experiencing loneliness, and 5-29% of PWH are frail (depending on the definition used). The risk of death in individuals who are frail and lonely, or frail and socially isolated has recently been estimated to be 1·8 times that in individuals who are not frail, lonely, or socially isolated. The aim of the present study was to determine the prevalence of loneliness, and other vulnerabilities related to ageing, in frail older adults with HIV., Methods: We assessed frailty with the Clinical Frailty Scale (CFS) in a cross-sectional, convenience sample of people with HIV aged 50 years or older in Southern Alberta, Canada. All Southern Alberta Clinic patients aged 50 years or older who attended a virtual or in-person clinic visit between March and October, 2020, and who underwent frailty screening were included in the present analyses. Individuals scoring 4 or higher on the CFS then completed a structured questionnaire to provide information on additional co-factors, including loneliness (Three-item Loneliness Scale), falls, impaired gait and balance, polypharmacy, unintentional weight loss, food insecurity, and subjective cognitive concerns. Age, sex, nadir CD4 cell count, duration of known HIV infection, ethnicity, and risk category were evaluated for associations with frailty. We used t tests to compare means and Pearson χ 2 tests to compare proportions. Patients gave written informed consent for use of data. The use of data was approved by the University of Calgary Conjoint Heath Research Ethics Board., Findings: We assessed frailty in 292 older people with HIV. The mean age was 59 years (range 50-86 years) and 45 (16%) were women. On the basis of a score of 4 or greater on the CFS, 40 (14%) participants were identified as frail. Frail individuals tended to be older than those who were not frail (mean age 61·9 years, SD 8·5 versus 58·4 years, SD 6·3; t test difference 3·5, 95% CI 1·3-5·7; p=0·0011). However, there was no association between frailty status and sex, nadir CD4 cell count, duration of known HIV infection, or self-reported ethnicity. Frail individuals were more likely to report injection drug use as a component of their risk for acquisition than were non-frail individuals. Of the frail participants, 15 (42%) reported loneliness, 15 (42%) had fallen in the past year, and 18 (50%) reported impaired gait or balance. One-fifth (8) reported unintentional weight loss and 12 (33%) experienced food insecurity. Nearly 40% (14) reported subjective memory concerns., Interpretation: In this sample of ageing people with HIV, frailty and loneliness were prevalent. Given the increased risk of death when frailty and loneliness are both present, upstream and targeted interventions are urgently needed. These might include measures to address loneliness, risk of falls, weight loss, food insecurity, and memory concerns., Funding: Canadian Foundation for Healthcare Improvement, Advancing Frailty Care in the Community., (Copyright © 2022 Elsevier Ltd.

The rotenone-induced animal model of Parkinson's disease (PD) has been used to investigate the pathogenesis of PD. Oxidative stress is one of the main contributors of neurodegeneration in PD. Flavonoids have the potential to modulate neuronal function and combat various neurodegenerative diseases. The pre- and post-supplementation of quercetin (50 mg/kg, p.o) was done in rats injected with rotenone (1.5 mg/kg, s.c). After the treatment, behavioral activities were monitored for motor activity, depression-like behavior, and cognitive changes. Rats were decapitated after behavioral analysis and the brain samples were dissected out for neurochemical and biochemical estimation. Results showed that supplementation of quercetin significantly (p<0.01) restored rotenone-induced motor and non-motor deficits (depression and cognitive impairments), enhanced antioxidant enzyme activities (p<0.01), and attenuated neurotransmitter alterations (p<0.01). It is suggested that quercetin supplementation improves neurotransmitter levels by mitigating oxidative stress via increasing antioxidant enzyme activity and hence improves motor activity, cognitive functions, and reduces depressive behavior. The results of the present study showed that quercetin pre-supplementation produced more significant results as compared to post-supplementation. These findings show that quercetin can be a potential therapeutic agent to reduce the risk and progression of PD., Competing Interests: The authors have declared that no competing interests exist.

Rheumatoid arthritis (RA) is a slowly progressing inflammatory autoimmune disease. Several features are involved in the RA pathogenesis in addition to environmental and genetic factors. Previously it has been reported that acetyl cholinesterase (AChE) activity is enhanced in old age and may contribute in the progression of RA. The current experimental work was projected to assess the activity of physostigmine (a cholinesterase inhibitor) for treatment of RA. In vitro and in vivo approaches were used for such evaluation. However, enzyme linked immunosorbent assays (ELISA) was performed to determine the concentrations of Prostaglandins E2 (PGE2) and tumor necrosis factor-α in arthritic rats after treatment with physostigmine. Moreover, anti-oxidant assays were employed to calculate the level of super oxide dismutase (SOD) and catalase peroxidase (CAT) in tissue of treated animals. The results claimed the dose dependent protective and stabilizing effect of physostigmine on denaturation of albumin (egg and bovine serum) protein and human red blood cell membrane, respectively, through in vitro studies. Furthermore, the physostigmine (10 and 20 mg/kg) significantly (p < 0.001) reduced the swelling of paw after induction of arthritis with formaldehyde or complete Freund's adjuvant (CFA) as compared to arthritic control animals. Moreover, significant (p < 0.001) reduction in the levels of inflammatory markers (PGE2 and TNF-α) at doses of 10 and 20 mg/kg of physostigmine has been observed in ELISA test. Likewise, there was a prominent rise in levels of SOD and CAT in animals treated with physostigmine. These findings pharmacologically conclude the anti-arthritic effect of physostigmine., (© 2021.

Benzodiazepine administration is known to be related to tolerance and a withdrawal syndrome on sudden cessation. Thymol possesses multiple biological properties especially in the pathogenesis of different brain disorders. However, to the best of our knowledge there is no study that relates the use of thymol to benzodiazepine induced withdrawal symptoms. Therefore the aim of the current study was to investigate the usefulness of thymol in the treatment of benzodiazepine withdrawal syndrome in rats. Animals were divided into four groups, thymol (40mg/kg/ml), diazepam (4 mg/kg), thymol + diazepam and vehicle control group. The treatment was given for 14 days and then suddenly ceased. After 24 h animals were tested in different behavioral paradigms such as physical signs for withdrawal, marble burying test, inverted screen test, elevated plus maze, passive avoidance test and open field activity. The results of the present study revealed that co-administration of thymol significantly reduced the withdrawal symptoms induced by diazepam. Our results further suggest that administration of thymol not only ameliorates rebound anxiety associated with diazepam withdrawal but also improves motor and memory impairment in rats.

Ephedra, natural flora has been used traditionally to treat rheumatism since decades. The scientific evidence of anti-rheumatic effect of this plant has also been reported. But the anti-rheumatic activity of major constituent of this plant (ephedrine) has not been evaluated. Based on this, the current study was aimed to assess anti-arthritic activity of ephedrine by using in vitro and in vivo approaches. Correspondingly, enzyme linked immunosorbent assay was performed for the estimation of prostaglandins E2 (PGE2) and tumor necrosis factor-α (TNF-α) in serum of formaldehyde-induced arthritic animals. The results elaborated significant reduction in albumin denaturation and remarkable progress on stabilization of red blood cells outer membrane at higher concentration during in vitro experiments. The ephedrine (40mg/kg) revealed noteworthy (p<0.001) inhibition in paw swelling in animals intoxicated with albumin as well as formaldehyde as compared to animals of control group by in vivo results. In this assay, ephedrine (20 & 40 mg/kg orally) significantly suppressed the level of these inflammatory markers (PGE2 & TNF-α). Ephedrine exhibited anti-arthritic effect by decreasing pro-inflammatory cytokines (PGE2 & TNF-α). This experimental work pharmacologically supports the use of ephedrine as anti-rheumatic drug but limited to evaluate in immunological arthritic model.

The advancements in biotechnology over time have led to an increase in the demand of pure, soluble and functionally active proteins. Recombinant protein production has thus been employed to obtain high expression of purified proteins in bulk. E. coli is considered as the most desirable host for recombinant protein production due to its inexpensive and fast cultivation, simple nutritional requirements and known genetics. Despite all these benefits, recombinant protein production often comes with drawbacks, such as, the most common being the formation of inclusion bodies due to improper protein folding. Consequently, this can lead to the loss of the structure-function relationship of a protein. Apart from various strategies, one major strategy to resolve this issue is the use of molecular chaperones that act as folding modulators for proteins. Molecular chaperones assist newly synthesized, aggregated or misfolded proteins to fold into their native conformations. Chaperones have been widely used to improve the expression of various proteins which are otherwise difficult to produce in E. coli. Here, we discuss the structure, function, and role of major E. coli molecular chaperones in recombinant technology such as trigger factor, GroEL, DnaK and ClpB.

The interpretation of observations of cooling neutron star crusts in quasipersistent x-ray transients is affected by predictions of the strength of neutrino cooling via crust Urca processes. The strength of crust Urca neutrino cooling depends sensitively on the electron-capture and β-decay ground-state-to-ground-state transition strengths of neutron-rich rare isotopes. Nuclei with a mass number of A=61 are predicted to be among the most abundant in accreted crusts, and the last remaining experimentally undetermined ground-state-to-ground-state transition strength was the β decay of ^{61}V. This Letter reports the first experimental determination of this transition strength, a ground-state branching of 8.1&#95;{-3.1}^{+4.0}%, corresponding to a log ft value of 5.5&#95;{-0.2}^{+0.2}. This result was achieved through the measurement of the β-delayed γ rays using the total absorption spectrometer SuN and the measurement of the β-delayed neutron branch using the neutron long counter system NERO at the National Superconducting Cyclotron Laboratory at Michigan State University. This method helps to mitigate the impact of the pandemonium effect in extremely neutron-rich nuclei on experimental results. The result implies that A=61 nuclei do not provide the strongest cooling in accreted neutron star crusts as expected by some predictions, but that their cooling is still larger compared to most other mass numbers. Only nuclei with mass numbers 31, 33, and 55 are predicted to be cooling more strongly. However, the theoretical predictions for the transition strengths of these nuclei are not consistently accurate enough to draw conclusions on crust cooling. With the experimental approach developed in this work, all relevant transitions are within reach to be studied in the future.

Background: To determine the gender differences in neonatal mortality, stillbirths, and perinatal mortality in south Asia using the Global Network data from the Maternal Newborn Health Registry., Methods: This study is a secondary analysis of prospectively collected data from the three south Asian sites of the Global Network. The maternal and neonatal demographic, clinical characteristics, rates of stillbirths, early neonatal mortality (1-7 days), late neonatal mortality (8-28 days), mortality between 29-42 days and the number of infants hospitalized after birth were compared between the male and female infants., Results: Between 2010 and 2018, 297,509 births [154,790 males (52.03%) and 142,719 females (47.97%)] from two Indian sites and one Pakistani site were included in the analysis [288,859 live births (97.1%) and 8,648 stillbirths (2.9%)]. The neonatal mortality rate was significantly higher in male infants (33.2/1,000 live births) compared to their female counterparts (27.4/1,000, p < 0.001). The rates of stillbirths (31.0 vs. 26.9/1000 births) and early neonatal mortality (27.1 vs 21.6/1000 live births) were also higher in males. However, there were no significant differences in late neonatal mortality (6.3 vs. 5.9/1000 live births) and mortality between 29-42 days (2.1 vs. 1.9/1000 live births) between the two groups. More male infants were hospitalized within 42 days after birth (1.8/1000 vs. 1.3/1000 live births, p < 0.001) than females., Conclusion: The risks of stillbirths, and early neonatal mortality were higher among male infants than their female counterparts. However, there was no gender difference in mortality after 7 days of age. Our results highlight the importance of stratifying neonatal mortality into early and late neonatal period to better understand the impact of gender on neonatal mortality. The information from this study will help in developing strategies and identifying measures that can reduce differences in sex-specific mortality.

Background: Few studies have shown how the move toward institutional delivery in low and middle-income countries (LMIC) impacts stillbirth and newborn mortality., Objectives: The study evaluated trends in institutional delivery in research sites in Belagavi and Nagpur India, Guatemala, Kenya, Pakistan, and Zambia from 2010 to 2018 and compared them to changes in the rates of neonatal mortality and stillbirth., Methods: We analyzed data from a nine-year interval captured in the Global Network (GN) Maternal Newborn Health Registry (MNHR). Mortality rates were estimated from generalized estimating equations controlling for within-cluster correlation. Cluster-level analyses were performed to assess the association between institutional delivery and mortality rates., Results: From 2010 to 2018, a total of 413,377 deliveries in 80 clusters across 6 sites in 5 countries were included in these analyses. An increase in the proportion of institutional deliveries occurred in all sites, with a range in 2018 from 57.7 to 99.8%. In 2010, the stillbirth rates ranged from 19.3 per 1000 births in the Kenyan site to 46.2 per 1000 births in the Pakistani site and by 2018, ranged from 9.7 per 1000 births in the Belagavi, India site to 40.8 per 1000 births in the Pakistani site. The 2010 neonatal mortality rates ranged from 19.0 per 1000 live births in the Kenyan site to 51.3 per 1000 live births in the Pakistani site with the 2018 neonatal mortality rates ranging from 9.2 per 1000 live births in the Zambian site to 50.2 per 1000 live births in the Pakistani site. In multivariate modeling, in some but not all sites, the reductions in stillbirth and neonatal death were significantly associated with an increase in the institutional deliveries., Conclusions: There was an increase in institutional delivery rates in all sites and a reduction in stillbirth and neonatal mortality rates in some of the GN sites over the past decade. The relationship between institutional delivery and a decrease in mortality was significant in some but not all sites. However, the stillbirth and neonatal mortality rates remain at high levels. Understanding the relationship between institutional delivery and stillbirth and neonatal deaths in resource-limited environments will enable development of targeted interventions for reducing the mortality burden., Trial Registration: The study is registered at clinicaltrials.gov .

Background: Neonatal deaths in first 28-days of life represent 47% of all deaths under the age of five years globally and are a focus of the United Nation's (UN's) Sustainable Development Goals. Pregnant women are delivering in facilities but that does not indicate quality of care during delivery and the postpartum period. The World Health Organization's Essential Newborn Care (ENC) package reduces neonatal mortality, but lacks a simple and valid composite index that measures its effectiveness., Methods: Data on 5 intra-partum and 3 post-partum practices (indicators) recommended as part of ENC, routinely collected in NICHD's Global Network's (GN) Maternal Newborn Health Registry (MNHR) between 2010 and 2013, were included. We evaluated if all 8 practices (Care around Delivery - CAD), combined as an index was associated with reduced early neonatal mortality rates (days 0-6 of life)., Results: A total of 150,848 live births were included in the analysis. The individual indicators varied across sites. All components were present in 19.9% births (range 0.4 to 31% across sites). Present indicators (8 components) were associated with reduced early neonatal mortality [adjusted RR (95% CI):0.81 (0.77, 0.85); p < 0.0001]. Despite an overall association between CAD and early neonatal mortality (RR < 1.0 for all early mortality): delivery by skilled birth attendant; presence of fetal heart and delayed bathing were associated with increased early neonatal mortality., Conclusions: Present indicators (8 practices) of CAD were associated with a 19% reduction in the risk of neonatal death in the diverse health facilities where delivery occurred within the GN MNHR. These indicators could be monitored to identify facilities that need to improve compliance with ENC practices to reduce preventable neonatal deaths. Three of the 8 indicators were associated with increased neonatal mortality, due to baby being sick at birth. Although promising, this composite index needs refinement before use to monitor facility-based quality of care in association with early neonatal mortality. Trial registration The identifier of the Maternal Newborn Health Registry at ClinicalTrials.gov is NCT01073475.

Background: Experience surveys provide an opportunity for patients to give their feedback about health care processes and services. Unfortunately, the most current surveys have been designed as "one-size fits-all" tools, and thus, do not take into account items pertaining to specific clinical groups. The objective of this study was to gain a deeper understanding of the specific aspects of care deemed important to cardiac surgery patients., Methods: Individual semistructured telephone interviews were conducted with a cohort of patients who had previously underwent cardiac surgery. Interviews were recorded and transcribed. Using a phenomenological approach, a thematic analysis was used to generate a list of themes and subthemes deemed important by participants., Results: Eight interviews were conducted in July and August 2019. Participants included 7 men and 1 woman, ranging from 55 to 84 years of age. Five key themes emerged from the data: (1) overall experience; (2) communication; (3) the physical hospital environment; (4) care needs and ongoing management; and (5) person-centred care. Our interviews revealed that participants had many overwhelmingly positive experiences with care. Through reports of their own experiences, participants highlighted important areas that might be improved., Conclusions: Our results confirm and expand upon those highlighted in quantitative research by our group. Findings and knowledge derived from this study might be used to inform quality improvement activities. These might also play a key role in the development of a patient experience survey, specifically for those who undergo cardiac surgery; thus addressing a potential limitation of surveys currently in use., (© 2020 Canadian Cardiovascular Society.

Background: Babies born weighing ≥ 2500 g account for more than 80% of the births in most resource-limited locations and for nearly 50% of the 28-day neonatal deaths. In contrast, in high-resource settings, 28-day neonatal mortality among this group represents only a small fraction of the neonatal deaths. Yet mortality risks for birth weight of ≥ 2500 g is limited. Knowledge regarding the factors associated with mortality in these babies will help in identifying interventions that can reduce mortality., Methods: The Global Network's Maternal Newborn Health Registry (MNHR) is a prospective, population-based observational study that includes all pregnant women and their pregnancy outcomes in defined geographic communities that has been conducted in research sites in six low-middle income countries (India, Pakistan, Democratic Republic of Congo, Guatemala, Kenya and Zambia). Study staff enroll all pregnant women as early as possible during pregnancy and conduct follow-up visits to ascertain delivery and 28-day neonatal outcomes. We analyzed the neonatal mortality rates (NMR) and risk factors for deaths by 28 days among all live-born babies with a birthweight ≥ 2500 g from 2010 to 2018 across the Global Network sites., Results: Babies born in the Global Network sites from 2010 to 2018 with a birthweight ≥ 2500 g accounted for 84.8% of the births and 45.4% of the 28-day neonatal deaths. Among this group, the overall NMR was 13.1/1000 live births. The overall 28-day NMR for ongoing clusters was highest in Pakistan (29.7/1000 live births) and lowest in the Zambian/Kenyan sites (9.3/1000) for ≥ 2500 g infants. ≥ 2500 g NMRs declined for Zambia/Kenya and India. For Pakistan and Guatemala, the NMR remained almost unchanged over the period. The ≥ 2500 g risks related to maternal, delivery and newborn characteristics varied by site. Maternal factors that increased risk and were common for all sites included nulliparity, hypertensive disease, previous stillbirth, maternal death, obstructed labor, severe postpartum hemorrhage, and abnormal fetal presentation. Neonatal characteristics including resuscitation, hospitalization, congenital anomalies and male sex, as well as lower gestational ages and birthweights were also associated with increased mortality., Conclusions: Nearly half of neonatal deaths in the Global Network sites occurred in infants born weighing ≥ 2500 g. The NMR for those infants was 13.1 per 1000 live births, much higher than rates usually seen in high-income countries. The changes in NMR over time varied across the sites. Even among babies born ≥ 2500 g, lower gestational age and birthweight were largely associated with increased risk of mortality. Since many of these deaths should be preventable, attention to preventing mortality in these infants should have an important impact on overall NMR., Trial Registration: https://ClinicalTrials.gov Identifier: NCT01073475.

Exposure to cadmium has been extensively increased due to its usage in modern daily life. Inside the human body it induces deteriorating effects in every vital organ including brain. Oxidative stress has been widely implicated in neurotoxicity induced by cadmium exposure. Consumption of dietary source of exogenous antioxidants is one of the recommended ways to extenuate heavy metal-induced oxidative stress. The potential of nuts against heavy-metal induced neurotoxicity has not been investigated earlier. This study was, therefore, conducted to find out the antioxidant ability of almond and walnut in the prevention of cadmium-induced oxidative stress. Rats were treated with nuts (400 mg/kg) daily for 28 days whereas, cadmium (50 mg/kg) was given once in a week. Brain function was monitored in terms of memory performance using Morris water maze and elevated plus maze. Moreover, oxidative stress status was also evaluated. Results showed that weekly exposure of cadmium significantly reduced %memory retention, increased lipid per oxidation and inhibited antioxidant enzymes activity. When nuts supplemented rats were monitored for these parameters, it was observed that almond and walnut have a great potential to reduce cadmium-induced neurotoxicity as evident by decreased oxidative stress and improved memory function in cadmium intoxicated rats.

The size of a ΔK=0 M1 excitation strength has been determined for the first time in a predominantly axially deformed even-even nucleus. It has been obtained from the observation of a rare K-mixing situation between two close-lying J^{π}=1^{+} states of the nucleus ^{164}Dy with components characterized by intrinsic projection quantum numbers K=0 and K=1. Nuclear resonance fluorescence induced by quasimonochromatic linearly polarized γ-ray beams provided evidence for K mixing of the 1^{+} states at 3159.1(3) and 3173.6(3) keV in excitation energy from their γ-decay branching ratios into the ground-state band. The ΔK=0 transition strength of B(M1;0&#95;{1}^{+}→1&#95;{K=0}^{+})=0.008(1)μ&#95;{N}^{2} was inferred from a mixing analysis of their M1 transition rates into the ground-state band. It is in agreement with predictions from the quasiparticle phonon nuclear model. This determination represents first experimental information on the M1 excitation strength of a nuclear quantum state with a negative R-symmetry quantum number.

Background: Oligohydramnios is a condition of abnormally low amniotic fluid volume that has been associated with poor pregnancy outcomes. To date, the prevalence of this condition and its outcomes has not been well described in low and low-middle income countries (LMIC) where ultrasound use to diagnose this condition in pregnancy is limited. As part of a prospective trial of ultrasound at antenatal care in LMICs, we sought to evaluate the incidence of and the adverse maternal, fetal and neonatal outcomes associated with oligohydramnios., Methods: We included data in this report from all pregnant women in community settings in Guatemala, Pakistan, Zambia and the Democratic Republic of Congo (DRC) who received a third trimester ultrasound as part of the First Look Study, a randomized trial to assess the value of ultrasound at antenatal care. Using these data, we conducted a planned secondary analysis to compare pregnancy outcomes of women with to those without oligohydramnios. Oligohydramnios was defined as measurement of an Amniotic Fluid Index less than 5 cm in at least one ultrasound in the third trimester. The outcomes assessed included maternal morbidity and fetal and neonatal mortality, preterm birth and low-birthweight. We used pairwise site comparisons with Tukey-Kramer adjustment and multivariable logistic models using general estimating equations to account for the correlation of outcomes within cluster., Results: Of 12,940 women enrolled in the clusters in Guatemala, Pakistan, Zambia and the DRC in the First Look Study who had a third trimester ultrasound examination, 87 women were diagnosed with oligohydramnios, equivalent to 0.7% of those studied. Prevalence of detected oligohydramnios varied among study sites; from the lowest of 0.2% in Zambia and the DRC to the highest of 1.5% in Pakistan. Women diagnosed with oligohydramnios had higher rates of hemorrhage, fetal malposition, and cesarean delivery than women without oligohydramnios. We also found unfavorable fetal and neonatal outcomes associated with oligohydramnios including stillbirths (OR 5.16, 95%CI 2.07, 12.85), neonatal deaths < 28 days (OR 3.18, 95% CI 1.18, 8.57), low birth weight (OR 2.10, 95% CI 1.44, 3.07) and preterm births (OR 2.73, 95%CI 1.76, 4.23). The mean birth weight was 162 g less (95% CI -288.6, - 35.9) with oligohydramnios., Conclusions: Oligohydramnos was associated with worse neonatal, fetal and maternal outcomes in LMIC. Further research is needed to assess effective interventions to diagnose and ultimately to reduce poor outcomes in these settings., Trial Registration: NCT01990625.

Background: Pakistan reports the highest stillbirth rate in the world at 43 per thousand births with more than three-quarters occurring in rural areas. The Global Network for Women's and Children's Health maintains a Maternal and Newborn Health Registry (MNHR) in 14 study clusters of district Thatta, Sindh Pakistan. For the last 10 years, the MNHR has recorded a high stillbirths rate with a slow decline. This exploratory study was designed to understand the perspectives of women and traditional birth attendants regarding the high occurrence of stillbirth in Thatta district., Methods: We used an exploratory qualitative study design by conducting in-depth interviews (IDIs) and focus group discussions (FGDs) using semi-structured interview guide with rural women (FGDs = 4; n = 29) and traditional birth attendants (FGDs = 4; n = 14) who were permanent residents of Thatta. In addition, in-depth interviews were conducted with women who had experienced a stillbirth (IDIs = 4). This study presents perceptions and experiences of women and TBAs regarding high rate of stillbirth in Thatta district, Karachi., Results: Women showed reluctance to receive skilled/ standard care when in need due to apprehensions towards operative delivery, poor attitude of skilled health care providers, and poor quality of care as service delivery factors. High cost of care, far distance to facility, lack of transport and need of an escort from the family or village to visit a health facility were additional important factors for not seeking care resulting in stillbirth. The easy availability of unskilled provider in the form of traditional birth attendant is then preferred over a skilled health care provider. TBAs shared their husband or family members restrict them to visit or consult a doctor during pregnancy. According to TBAs after delivering a macerated fetus, women are given herbs to remove infection from woman's body and uterus. Further women are advised to conceive soon so that they get rid of infections., Conclusion: Women of this rural community carry lots of apprehension against skilled medical care and as a result follow traditional practices. Conscious efforts are required to increase the awareness of women to develop positive health seeking behavior during pregnancy, delivery and the post-partum period. Alongside, provision of respectful maternity care needs to be emphasized especially at public health facilities.

National organizations have developed guidelines and tools for antimicrobial stewardship (AMS) in post-acute and long-term care (PALTC), but there is a need to effectively translate these into actionable, measurable, and impactful programs. An electronic needs assessment survey was developed and distributed to health care providers and administrators involved with AMS activities in PALTC facilities in Maryland. The results of this survey were used to develop a statewide initiative to improve AMS in nursing facilities. The survey revealed that barriers to implementing AMS include limited access or poor utilization of experts in AMS and infectious disease, adverse event data collection tools, and locally developed protocols and guidelines. Strategies to improve AMS included the provision of free continuing education to a multidisciplinary audience and improved access to individuals with expertise in infectious disease and the development of an adverse drug event tool.

Preventing influenza infections is a national health priority, particularly among geriatric and adults with frailty who reside in post-acute and long-term care (PALTC) settings. Older adults account for more than 70% of deaths from influenza, a reflection of decreased vaccine effectiveness in that age group. Annually vaccinating health care personnel (HCP) working with these patients against influenza is critical to reducing influenza morbidity and mortality among patients. PALTC HCP have the lowest influenza vaccination rate when compared to HCP in other settings. The Advisory Committee on Immunization Practices recommends that all HCP receive an annual influenza vaccination, including those who do not have direct patient care responsibilities. Here, we discuss the importance of influenza vaccination for HCP, detail recommendations for influenza vaccination practice and procedures for PALTC settings, and offer support to PALTC settings and their staff on influenza vaccinations., (Copyright © 2019 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Background: A number of non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin, indomethacin, ibuprofen, flufenamic acid, and phenylbutazone are being clinically used to treat inflammatory disorders. These NSAIDs are associated with serious side effects such as gastric ulceration, nephrotoxicity, and bleeding. Therefore, the identification of potent and safe therapy for inflammatory disorders is still of great interest to the medicinal chemist., Methods: A series of varyingly substituted benzoyl, acetyl, alkyl ester, and sulfonate ester substituted coumarins 1-64 were screened for the inhibition of ROS, generated from zymosan activated whole blood phagocytes, using luminol-enhanced chemiluminescence technique., Results: Among all tested compounds, 8 (IC 50 = 65.0 ± 3.1 μM), 24 (IC 50 = 41.8 ± 1.5 μM), 26 (IC 50 = 10.6 ± 2.8 μM), 28 (IC 50 = 20.9 ± 1.5 μM), and 41 (IC 50 = 4.6 ± 0.3 μM) showed good anti- inflammatory potential as compared to standard antiinflammatory drug ibuprofen (IC 50 = 54.3 ± 1.9 μM). Specifically, compounds 24, 26, 28, and 41 showed superior activity than standard antiinflammatory drug. Furthermore, compounds 12 (IC 50 = 219.0 ± 1.4 μM), 14 (IC 50 = 216.5 ± 6.2 μM), 16 (IC50 = 187.4 ± 2.2 μM), and 20 (IC 50 = 196.2 ± 2.0 μM) showed moderate ROS inhibitory activity. Limited SAR study revealed that the hydroxy-substituted compound showed better ROS inhibition potential in case of 3-benzoyl and 3-ethylester coumarin derivatives. Whereas, chloro substitution was found to be important in case of 3-acetyl coumarin derivatives. Similarly, in case of sulfonate ester, chloro, and nitro groups especially at positions -4 and -3 of ring "R" played vital role in ROS inhibition. Furthermore, cytotoxicity of all active compounds was also checked on NIH-3T3 cell line. Compounds 12, 14, and 20 were found to be non-cytotoxic. Whereas, 8, 16, 24, 26, 28, and 41 were found to be very weak cytotoxic as compared to standard cycloheximide (IC 50 = 0.13 ± 0.02 μM)., Conclusion: Identified ROS inhibitors offer the possibility of additional modifications that could give rise to lead structures for further research in order to obtain more potent, and safer antiinflammatory agent., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Objective: There is an ongoing challenge of effective integration between primary and social care in the United Kingdom; current systems have led to fragmentation of services preventing holistic patient-centred care for vulnerable populations. To improve clinical outcomes and achieve financial efficiencies, the barriers to integration need to be identified and addressed. This study aims to explore the unique perspectives of frontline staff (general practitioners and practice managers) towards these barriers to integration., Design: Qualitative study using semistructured interviews and thematic analysis to obtain results., Setting: General practices within London., Participants: 18 general practitioners (GPs) and 7 practice managers (PMs) based in London with experience of working with social care., Results: The study identified three overarching themes where frontline staff believed problems exist: accessing social services, interprofessional relationships and infrastructure. Issues with contacting staff from other sectors creates delays in referrals for patient care and perpetuates existing logistical challenges. Likewise, professionals noted a hostile working culture between sectors that has resulted in silo working mentalities. In addition to staff being overworked as well as often inefficient multidisciplinary team meetings, poor relationships across sectors cause a diffusion of responsibility, impacting the speed with which patient requests are responded to. Furthermore, participants identified that a lack of interoperability between information systems, lack of pooled budgets and misaligned incentives between managerial staff compound the infrastructural divide between both sectors., Conclusion: In this study, primary care staff identify intangible barriers to integration such as poor interprofessional relationships, in addition to more well-described structural issues such as insufficient funding and difficulty accessing social care. Participants believe that educating the next generation of medical professionals may lead to the development of collaborative, instead of siloed, working cultures and that change is needed at both an interpersonal and institutional level to successfully integrate care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Recent World Health Organization (WHO) antenatal care recommendations include an ultrasound scan as a part of routine antenatal care. The First Look Study, referenced in the WHO recommendation, subsequently shows that the routine use of ultrasound during antenatal care in rural, low-income settings did not improve maternal, fetal or neonatal mortality, nor did it increase women's use of antenatal care or the rate of hospital births. This article reviews the First Look Study, reconsidering the assumptions upon which it was built in light of these results, a supplemental descriptive study of interviews with patients and sonographers that participated in the First Look study intervention, and a review of the literature. Two themes surface from this review. The first is that focused emphasis on building the pregnancy risk screening skills of rural primary health care personnel may not lead to adaptations in referral hospital processes that could benefit the patient accordingly. The second is that agency to improve the quality of patient reception at referral hospitals may need to be manufactured for obstetric ultrasound screening, or remote pregnancy risk screening more generally, to have the desired impact. Stemming from the literature, this article goes on to examine the potential for complementarity between obstetric ultrasound screening and another approach encouraged by the WHO, the maternity waiting home. Each approach may address existing shortcomings in how the other is currently understood. This paper concludes by proposing a path toward developing and testing such a hybrid approach., (Copyright © 2019 The Authors. Published by Elsevier Inc. All rights reserved.)

Unpredictable chronic mild stress (UCMS) model is the most established method to study neurobiological mechanisms of depression. This work was intended to explore the efficacy of curcumin to revert the UCMS-induced oxidative burden and associated depression as well as potential of curcumin as an acetyl cholinesterase (AchE) inhibitor. Animals were initially grouped into control and curcumin (200mg/kg, p.o) and further subdivided into unstressed and stressed groups. Depression and anxiety were evaluated by forced swim test (FST) and light/dark transition (LDT) while memory function was assessed by passive avoidance test (PAT). Effect of curcumin on oxidative stress following UCMS was determined by measuring peroxidation of lipid (LPO) and antioxidant enzyme activities. AchE activity was also determined. Findings showed that curcumin supplementation significantly attenuated the UCMS-induced depression and anxiety like symptoms, decreased the load of UCMS propagated oxidative stress by improving antioxidant enzymes activities. Curcumin also improved the memory function and exhibited inhibitory effect on AchE activity. In conclusion it can be suggested that supplementation of curcumin in daily life can help in combating the stress-induced depression and ever increasing load of oxidative stress. Study also highlights the anti-acetylcholinesterase potential of curcumin which may be responsible for improved memory function following UCMS.

The β-delayed γ-ray spectroscopy of neutron-rich ^{123,125}Ag isotopes is investigated at the Radioactive Isotope Beam Factory of RIKEN, and the long-predicted 1/2^{-} β-emitting isomers in ^{123,125}Ag are identified for the first time. With the new experimental results, the systematic trend of energy spacing between the lowest 9/2^{+} and 1/2^{-} levels is extended in Ag isotopes up to N=78, providing a clear signal for the reduction of the Z=40 subshell gap in Ag towards N=82. Shell-model calculations with the state-of-the-art V&#95;{MU} plus M3Y spin-orbit interaction give a satisfactory description of the low-lying states in ^{123,125}Ag. The tensor force is found to play a crucial role in the evolution of the size of the Z=40 subshell gap. The observed inversion of the single-particle levels around ^{123}Ag can be well interpreted in terms of the monopole shift of the π1g&#95;{9/2} orbitals mainly caused by the increasing occupation of ν1h&#95;{11/2} orbitals.

Background: A pilot study to identify if the delivery of teaching session to medical students would have the potential to enhance communication and a culture of integration between primary and social care, ultimately improving interprofessional relationships between primary and social care. Health and social care integration is a topic of great debate in the developed world and the focus of the upcoming Green Paper by the Secretary of State for Health and Social Care in the NHS. There is much uncertainty to how this should be done and is hindered by the various current barriers. The literature identifies that collaborative cultures encourage effective interprofessional relationships and that communication is vital to integration of primary and social care and should be established early in medical training. Materials and Method: The General Medical Council's Outcomes for Graduates and Imperial College School of Medicine curriculum were reviewed out to identify outcomes relating to inter-professional relationships between primary and social care. The relevant year group was surveyed to identify if the learning objective was delivered. In order to determine if delivery of a teaching session on nurturing interprofessional relationships between primary and social care would be effective, it was delivered to early clinical years to measure benefits as a pilot study. This was devised of case-based scenarios derived from learning objectives developed with experienced health care professionals. A survey was administered before and after the teaching session to determine if the students felt they had improved with respect to the learning objectives. Results: The initial survey identified the majority of students found the learning objectives were not delivered. The teaching session found a statistically significant improvement in confidence to nurture interprofessional relationships between primary and social care. Conclusion: Effective interprofessional relationships between primary and social care, improving communication and collaborative cultures, can be effectively taught in medical school, to improve integration of primary and social care., Competing Interests: The authors report no conflicts of interest in this work.

Texas Tech Pediatrics at Northwest Texas Hospital System in Amarillo, Texas, currently practices giving "Mom/Dad of the Day" cards to all new parents, offering the opportunity for fathers to auscultate the newborn heart sound, and encouraging maternal and paternal skin-to-skin contact. New parents were asked to fill out 2 anonymous surveys regarding these practices. Survey results showed statistically significant positive responses by the parents for subjective improvement in fetal sleep and feeding as well as parental confidence and preparedness for taking care of their newborn. Additionally, these practices are desired by parents, with 96% fathers recommending that the hospital routinely offering opportunities for heart auscultation and 94% parents recommending "Mom/Dad of the Day" cards for all future parents in the hospital. Small, nonmedical initiatives such as these are well received and can be feasibly adopted in more hospitals to improve patient quality of care.

Curcumin possesses wide spectrum of biological actions, on that account the current study was aimed to investigate the beneficial effectiveness of curcumin on memory and oxidative stress if any, over synthetic drug donepezil approved for the treatment of memory disorders. Eighteen Albino wistar (male) rats were divided into 3 groups namely vehicle control which received neutral oil orally and 0.9% saline intraperitoneally, curcumin which received curcumin orally dissolved in neutral oil at the dose of 100mg/ml/kg for seven days, donepezil which received donepezil intraperitoneally at the dose of 1mg/ml/kg for seven days. To assess memory and cognition Elevated Plus Maze and Morris Water Maze tests were performed. Rats were sacrificed after behavioral analysis and their brains were removed for biochemical assays including lipid peroxidation and antioxidant enzymes such as catalase, superoxide dismutase, glutathione peroxidase. Acetylcholine esterase activity and acetylcholine levels were also determined. Our results showed that both curcumin and donepezil improved memory and inhibited acetylcholinesterase, however curcumin inhibited AchE with more potency than donepezil when compared to vehicle control rats. Moreover curcumin exhibited greater antioxidant potential to decrease the load of oxidative stress in brain cells than donepezil as compared to vehicle control rats. In conclusion present study proposed that increased antioxidant potential of curcumin may be responsible for its increased acetylcholine levels and associated enhanced memory performance.

Background: Ultrasound during antenatal care (ANC) is proposed as a strategy for increasing hospital deliveries for complicated pregnancies and improving maternal, fetal, and neonatal outcomes. The First Look study was a cluster-randomized trial conducted in the Democratic Republic of Congo, Guatemala, Kenya, Pakistan and Zambia to evaluate the impact of ANC-ultrasound on these outcomes. An additional survey was conducted to identify factors influencing women with complicated pregnancies to attend referrals for additional care., Methods: Women who received referral due to ANC ultrasound findings participated in structured interviews to characterize their experiences. Cochran-Mantel-Haenszel statistics were used to examine differences between women who attended the referral and women who did not. Sonographers' exam findings were compared to referred women's recall., Results: Among 700 referred women, 510 (71%) attended the referral. Among referred women, 97% received a referral card to present at the hospital, 91% were told where to go in the hospital, and 64% were told that the hospital was expecting them. The referred women who were told who to see at the hospital (88% vs 66%), where to go (94% vs 82%), or what should happen, were more likely to attend their referral (68% vs 56%). Barriers to attending referrals were cost, transportation, and distance. Barriers after reaching the hospital were substantial. These included not connecting with an appropriate provider, not knowing where to go, and being told to return later. These barriers at the hospital often led to an unsuccessful referral., Conclusions: Our study found that ultrasound screening at ANC alone does not adequately address barriers to referrals. Better communication between the sonographer and the patient increases the likelihood of a completed referral. These types of communication include describing the ultrasound findings, including the reason for the referral, to the mother and staff; providing a referral card; describing where to go in the hospital; and explaining the procedures at the hospital. Thus, there are three levels of communication that need to be addressed to increase completion of appropriate referrals-communication between the sonographer and the woman, the sonographer and the clinic staff, and the sonographer and the hospital., Trial Registration: NCT01990625 .

Objective: Ultrasound is widely regarded as an important adjunct to antenatal care (ANC) to guide practice and reduce perinatal mortality. We assessed the impact of ANC ultrasound use at health centres in resource-limited countries., Design: Cluster randomised trial., Setting: Clusters within five countries (Democratic Republic of Congo, Guatemala, Kenya, Pakistan, and Zambia) METHODS: Clusters were randomised to standard ANC or standard care plus two ultrasounds and referral for complications. The study trained providers in intervention clusters to perform basic obstetric ultrasounds., Main Outcome Measures: The primary outcome was a composite of maternal mortality, maternal near-miss mortality, stillbirth, and neonatal mortality., Results: During the 24-month trial, 28 intervention and 28 control clusters had 24 263 and 23 160 births, respectively; 78% in the intervention clusters received at least one study ultrasound; 60% received two. The prevalence of conditions noted including twins, placenta previa, and abnormal lie was within expected ranges. 9% were referred for an ultrasound-diagnosed condition, and 71% attended the referral. The ANC (RR 1.0 95% CI 1.00, 1.01) and hospital delivery rates for complicated pregnancies (RR 1.03 95% CI 0.89, 1.20) did not differ between intervention and control clusters nor did the composite outcome (RR 1.09 95% CI 0.97, 1.23) or its individual components., Conclusions: Despite availability of ultrasound at ANC in the intervention clusters, neither ANC nor hospital delivery for complicated pregnancies increased. The composite outcome and the individual components were not reduced., Tweetable Abstract: Antenatal care ultrasound did not improve a composite outcome that included maternal, fetal, and neonatal mortality., (© 2018 Royal College of Obstetricians and Gynaecologists.)

Objective: The objective of this study was to describe the relationship between early pregnancy body mass index (BMI) and maternal, perinatal, and neonatal outcomes in rural India and Pakistan., Study Design: In a prospective, population-based pregnancy registry implemented in communities in Thatta, Pakistan and Nagpur and Belagavi, India, we obtained women's BMI prior to 12 weeks' gestation (categorized as underweight, normal, overweight, and obese following World Health Organization criteria). Outcomes were assessed 42 days postpartum., Results: The proportion of women with an adverse maternal outcome increased with increasing maternal BMI. Less than one-third of nonoverweight/nonobese women, 47.2% of overweight women, and 56.0% of obese women experienced an adverse maternal outcome. After controlling for site, maternal age and parity, risks of hypertensive disease/severe preeclampsia/eclampsia, cesarean/assisted delivery, and antibiotic use were higher among women with higher BMIs. Overweight women also had significantly higher risk of perinatal and early neonatal mortality compared with underweight/normal BMI women. Overweight women had a significantly higher perinatal mortality rate., Conclusion: High BMI in early pregnancy was associated with increased risk of adverse maternal, perinatal, and neonatal outcomes in rural India and Pakistan. These findings present an opportunity to inform efforts for women to optimize weight prior to conception to improve pregnancy outcomes., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Background: Stillbirth rates remain high, especially in low and middle-income countries, where rates are 25 per 1000, ten-fold higher than in high-income countries. The United Nations' Every Newborn Action Plan has set a goal of 12 stillbirths per 1000 births by 2030 for all countries., Methods: From a population-based pregnancy outcome registry, including data from 2010 to 2016 from two sites each in Africa (Zambia and Kenya) and India (Nagpur and Belagavi), as well as sites in Pakistan and Guatemala, we evaluated the stillbirth rates and rates of annual decline as well as risk factors for 427,111 births of which 12,181 were stillbirths., Results: The mean stillbirth rates for the sites were 21.3 per 1000 births for Africa, 25.3 per 1000 births for India, 56.9 per 1000 births for Pakistan and 19.9 per 1000 births for Guatemala. From 2010 to 2016, across all sites, the mean stillbirth rate declined from 31.7 per 1000 births to 26.4 per 1000 births for an average annual decline of 3.0%. Risk factors for stillbirth were similar across the sites and included maternal age < 20 years and age > 35 years. Compared to parity 1-2, zero parity and parity > 3 were both associated with increased stillbirth risk and compared to women with any prenatal care, women with no prenatal care had significantly increased risk of stillbirth in all sites., Conclusions: At the current rates of decline, stillbirth rates in these sites will not reach the Every Newborn Action Plan goal of 12 per 1000 births by 2030. More attention to the risk factors and treating the causes of stillbirths will be required to reach the Every Newborn Action Plan goal of stillbirth reduction., Trial Registration: NCT01073475 .

Post-traumatic stress disorder (PTSD) is a condition which is triggered shortly after experiencing traumatic events. PTSD is complicated by the fact that people with PTSD often develop additional disorders such as phobias, addiction, depression, panic disorder and obsessive-compulsive disorder. Beta-adrenergic and cholinergic system both are involved in memory formation as well as in emotional response associated with memory. It is reported that the administration of beta-adrenergic and cholinergic antagonist results in the impairment in memory formation. Here, we examined the potential of beta-adrenergic antagonist propranolol and muscarinic cholinergic antagonist atropine for impairing the recently formed fear memory associated with PTSD. Reconsolidation is the memory process during which labile memory converts into permanent memory. In this study it is hypothesized that if recently formed fear memory is disturbed during reconsolidation phase by pharmacological intervention then it could be possible to impair well-consolidated fear memory. Atropine and propranolol were injected in separate set of rats (n=6) just after the reactivation of fear memory. Short term memory and long term memory were monitored after 2 h and 24 h of reactivation respectively. Results of current study demonstrated that only atropine showed significant impairment of reconsolidation of newly formed fear memory whereas propranolol did not show fear memory disrupting effects. The results emphasize the significance of pharmacological intervention to impair reconsolidation of newly formed fear memory.

This study was designed to investigate the role of enriched environment in preventing and/or reducing the neurobehavioral deficits produced after nicotine administration in albino Wistar rats. Equal numbers of rat in two groups were either placed in social environment (control group) or social along with physically enriched environment for four weeks before the administration of nicotine. Exposure to different environmental conditions was followed by the intraperitoneal injection of nicotine at the dose of 0.6 mg/kg for seven consecutive days during which addictive behavior was monitored using conditioned placed preference paradigm. Behavioral responses to locomotor activity, anxiety and retention of short term memory were investigated in control and nicotine injected groups exposed to different environments. Results of this study showed that the rats pre-exposed to physical along with social enrichment exhibited a decrease in drug seeking behavior, hyper locomotion, anxiogenic effects along with improvement of working memory as compared to control and nicotine injected groups that were kept in social environment alone. This behavioral study suggests that the exposure to physical enrichment along with socialization in young age can later reduce the chances of compulsive dependence on nicotine and related neurobehavioral deficits.

The level structure of the neutron-rich ^{77}Cu nucleus is investigated through β-delayed γ-ray spectroscopy at the Radioactive Isotope Beam Factory of the RIKEN Nishina Center. Ions of ^{77}Ni are produced by in-flight fission, separated and identified in the BigRIPS fragment separator, and implanted in the WAS3ABi silicon detector array, surrounded by Ge cluster detectors of the EURICA array. A large number of excited states in ^{77}Cu are identified for the first time by correlating γ rays with the β decay of ^{77}Ni, and a level scheme is constructed by utilizing their coincidence relationships. The good agreement between large-scale Monte Carlo shell model calculations and experimental results allows for the evaluation of the single-particle structure near ^{78}Ni and suggests a single-particle nature for both the 5/2&#95;{1}^{-} and 3/2&#95;{1}^{-} states in ^{77}Cu, leading to doubly magic ^{78}Ni.

Background: Disseminated intravascular coagulation (DIC)-positive kidneys have historically been turned down for fear of poor outcomes. Higher severity injuries, which are prone to DIC, are typically seen in younger, otherwise healthy potential donors. The continued kidney allograft shortage has generated interest in the use of these DIC-positive grafts. There have been some reports of acceptable outcomes of renal transplantation using kidneys from donors with DIC. There are multiple clinical series demonstrating good outcomes from DIC-positive kidneys when the extent of glomeruli containing fibrin thrombi is less than 50% and donor renal function is preserved. These grafts are frequently associated with a period of delayed graft function., Methods: We report 2 transplants with kidneys from brain dead donors with known DIC., Results: Both donors had renal failure and pretransplant renal biopsies showing 100% of the glomeruli containing fibrin thrombi. The recipients experienced delayed graft function requiring hemodialysis which was discontinued on postoperative days 18 and 39 for cases 1 and 2, respectively. Both patients are now over 14 months posttransplant with stable allograft function., Conclusions: Until clearer organ selection criteria are established, caution should be exercised when considering the use of kidneys with a similar phenotype and allocation decisions made by a multidisciplinary transplant team on a case-by-case basis.

Prior studies have suggested that obstetrical (OB) ultrasound in low- and middle-income countries has aided in detection of high-risk conditions, which in turn could improve OB management. We are participating in a cluster-randomized clinical trial of OB ultrasound, which is designed to assess the effect of basic OB ultrasound on maternal mortality, fetal mortality, neonatal mortality, and maternal near-miss in 5 low-income countries. We designed a 2-week course in basic OB ultrasound, followed by 12 weeks of oversight, to train health care professionals with no prior ultrasound experience to perform basic OB ultrasound to screen for high-risk pregnancies. All patients with high-risk pregnancies identified by the trainees were referred to higher-level health facilities where fully trained sonographers confirmed the diagnoses before any actions were taken. Although there have been several published studies on basic OB ultrasound training courses for health care workers in low- and middle-income countries, quality control reporting has been limited. The purpose of this study is to report on quality control results of these trainees. Health care workers trained in similar courses could have an adjunctive role in ultrasound screening for high-risk OB conditions where access to care is limited. After completion of the ultrasound course, 41 trainees in 5 countries performed 3801 ultrasound examinations during a 12-week pilot period. Each examination was reviewed by ultrasound trainers for errors in scanning parameters and errors in diagnosis, using predetermined criteria. Of the 32,480 images comprising the 3801 examinations, 94.8% were rated as satisfactory by the reviewers. There was 99.4% concordance between trainee and reviewer ultrasound diagnosis. The results suggest that trained health care workers could play a role in ultrasound screening for high-risk OB conditions., (Copyright © 2017 The Authors. Published by Elsevier Inc.

High quality is important in medical imaging, yet in many geographic areas, highly skilled sonographers are in short supply. Advances in Internet capacity along with the development of reliable portable ultrasounds have created an opportunity to provide centralized remote quality assurance (QA) for ultrasound exams performed at rural sites worldwide. We sought to harness these advances by developing a web-based tool to facilitate QA activities for newly trained sonographers who were taking part in a cluster randomized trial investigating the role of limited obstetric ultrasound to improve pregnancy outcomes in 5 low- and middle-income countries. We were challenged by connectivity issues, by country-specific needs for website usability, and by the overall need for a high-throughput system. After systematically addressing these needs, the resulting QA website helped drive ultrasound quality improvement across all 5 countries. It now offers the potential for adoption by future ultrasound- or imaging-based global health initiatives., (© Swanson et al.)

The β-decay intensity of ^{70}Co was measured for the first time using the technique of total absorption spectroscopy. The large β-decay Q value [12.3(3) MeV] offers a rare opportunity to study β-decay properties in a broad energy range. Two surprising features were observed in the experimental results, namely, the large fragmentation of the β intensity at high energies, as well as the strong competition between γ rays and neutrons, up to more than 2 MeV above the neutron-separation energy. The data are compared to two theoretical calculations: the shell model and the quasiparticle random phase approximation (QRPA). Both models seem to be missing a significant strength at high excitation energies. Possible interpretations of this discrepancy are discussed. The shell model is used for a detailed nuclear structure interpretation and helps to explain the observed γ-neutron competition. The comparison to the QRPA calculations is done as a means to test a model that provides global β-decay properties for astrophysical calculations. Our work demonstrates the importance of performing detailed comparisons to experimental results, beyond the simple half-life comparisons. A realistic and robust description of the β-decay intensity is crucial for our understanding of nuclear structure as well as of r-process nucleosynthesis.

Magnesium (Mg) is the fourth most abundant biological mineral essential for good health. Neuroprotective, anxiolytic and antidepressant effects of magnesium following stress and brain injuries are well established. In present study, we analyzed the protective effects of magnesium in rats exposed to sub-chronic noise stress. Magnesium Chloride (MgCl2, 100 mg/kg) was administered intraperitoneally once daily for 15 days prior exposure to noise stress. Rats were exposed to noise stress for 4 h after administration of magnesium for 15 days. At the end of treatment behavioral alterations were assessed. Animals were decapitated following behavioral testing and the brains were dissected out for neurochemical estimations by HPLC-EC. Improvement in noise-induced memory deficits as assessed by novel object recognition (NOR) test and elevated plus maze (EPM) test was found in magnesium treated rats. This improvement in noise-induced behavioral deficits following treatment with magnesium may be attributed to a significant decrease (p < 0.01) in dopamine (DA) and serotonin (5-hydroxytryptamine; 5-HT) turnover as compared to control rats observed in present work. These results suggest that treatment with magnesium can attenuate the noise-induced deficits and may be used as a therapy against noise-induced neurodegeneration. Moreover an adequate amount of magnesium in daily diet may help to develop the ability to resist against or cope up with stressful conditions encountered in daily life.

Nuclear reactions where an exotic nucleus captures a neutron are critical for a wide variety of applications, from energy production and national security, to astrophysical processes, and nucleosynthesis. Neutron capture rates are well constrained near stable isotopes where experimental data are available; however, moving far from the valley of stability, uncertainties grow by orders of magnitude. This is due to the complete lack of experimental constraints, as the direct measurement of a neutron-capture reaction on a short-lived nucleus is extremely challenging. Here, we report on the first experimental extraction of a neutron capture reaction rate on ^{69}Ni, a nucleus that is five neutrons away from the last stable isotope of Ni. The implications of this measurement on nucleosynthesis around mass 70 are discussed, and the impact of similar future measurements on the understanding of the origin of the heavy elements in the cosmos is presented.

Dietary nutrients may play a vital role in protecting the brain from age-related memory dysfunction and neurodegenerative diseases. Tree nuts including almonds have shown potential to combat age-associated brain dysfunction. These nuts are an important source of essential nutrients, such as tocopherol, folate, mono- and poly-unsaturated fatty acids, and polyphenols. These components have shown promise as possible dietary supplements to prevent or delay the onset of age-associated cognitive dysfunction. This study investigated possible protective potential of almond against scopolamine induced amnesia in rats. The present study also investigated a role of acetylcholine in almond induced memory enhancement. Rats in test group were orally administrated with almond suspension (400 mg/kg/day) for four weeks. Both control and almond-treated rats were then divided into saline and scopolamine injected groups. Rats in the scopolamine group were injected with scopolamine (0.5 mg/kg) five minutes before the start of each memory test. Memory was assessed by elevated plus maze (EPM), Morris water maze (MWM) and novel object recognition (NOR) task. Cholinergic function was determined in terms of hippocampal and frontal cortical acetylcholine content and acetylcholinesterase activity. Results of the present study suggest that almond administration for 28 days significantly improved memory retention. This memory enhancing effect of almond was also observed in scopolamine induced amnesia model. Present study also suggests a role of acetylcholine in the attenuation of scopolamine induced amnesia by almond., (Copyright © 2015 Elsevier Inc. All rights reserved.)

The updated Banff classification allows for the diagnosis of antibody-mediated rejection (AMR) in the absence of peritubular capillary C4d staining. Our objective was to quantify allograft loss risk in patients with consistently C4d-negative AMR (n = 51) compared with C4d-positive AMR patients (n = 156) and matched control subjects without AMR. All first-year posttransplant biopsy results from January 2004 through June 2014 were reviewed and correlated with the presence of donor-specific antibody (DSA). C4d-negative AMR patients were not different from C4d-positive AMR patients on any baseline characteristics, including immunologic risk factors (panel reactive antibody, prior transplant, HLA mismatch, donor type, DSA class, and anti-HLA/ABO-incompatibility). C4d-positive AMR patients were significantly more likely to have a clinical presentation (85.3% vs. 54.9%, p < 0.001), and those patients presented substantially earlier posttransplantation (median 14 [interquartile range 8-32] days vs. 46 [interquartile range 20-191], p < 0.001) and were three times more common (7.8% vs 2.5%). One- and 2-year post-AMR-defining biopsy graft survival in C4d-negative AMR patients was 93.4% and 90.2% versus 86.8% and 82.6% in C4d-positive AMR patients, respectively (p = 0.4). C4d-negative AMR was associated with a 2.56-fold (95% confidence interval, 1.08-6.05, p = 0.033) increased risk of graft loss compared with AMR-free matched controls. No clinical characteristics were identified that reliably distinguished C4d-negative from C4d-positive AMR. However, both phenotypes are associated with increased graft loss and thus warrant consideration for intervention., (© Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.)

It is observed that memories are more strengthened in a stressful condition. Studies have also demonstrated an association between stressful events and the onset of depression and anxiety. Considering the nootropic, anxiolytic and antidepressant-like properties of curcumin in various experimental approaches, we appraised the beneficial effects of this herb on acute immobilization stress-induced behavioral and neurochemical alterations. Rats in test group were administrated with curcumin (200mg/kg/day), dissolved in neutral oil, for 1 week. Both control and curcumin-treated rats were divided into unstressed and stressed groups. Rats in the stressed group were subjected to immobilization stress for 2h. After stress, the animals were subjected to behavioral tests. Immobilization stress induced an anxiogenic behavior in rats subjected to elevated plus maze test (EPM). Locomotor activity was also significantly increased following the acute immobilization stress. Pre-administration of curcumin prevented the stress-induced behavioral deficits. Highest memory performance was observed in stressed rats that were pre-treated with curcumin in Morris water maze (MWM). Brain malondialdehyde (MDA) levels, catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), and acetylcholinesterase (AChE) activities were also estimated. Present study suggests a role of antioxidant enzymes in the attenuation of acute stress induced anxiety by curcumin. The findings therefore suggest that supplementation of curcumin may be beneficial in the treatment of acute stress induced anxiety and enhancement of memory function., (Copyright © 2015 Elsevier Inc.

The β-decay half-lives of 110 neutron-rich isotopes of the elements from &#95;{37}Rb to &#95;{50}Sn were measured at the Radioactive Isotope Beam Factory. The 40 new half-lives follow robust systematics and highlight the persistence of shell effects. The new data have direct implications for r-process calculations and reinforce the notion that the second (A≈130) and the rare-earth-element (A≈160) abundance peaks may result from the freeze-out of an (n,γ)⇄(γ,n) equilibrium. In such an equilibrium, the new half-lives are important factors determining the abundance of rare-earth elements, and allow for a more reliable discussion of the r process universality. It is anticipated that universality may not extend to the elements Sn, Sb, I, and Cs, making the detection of these elements in metal-poor stars of the utmost importance to determine the exact conditions of individual r-process events.

Aims: D-Galactose (D-gal) induced accelerated senescence has been used to develop an aging model for brain. Previously, long term administration of a wide range of doses has been used for this purpose. In the present study we investigate whether short term administration of a high dose of D-gal in rats induces significant signs and symptoms similar to natural aging., Main Methods: Young rats were injected intraperitoneally with D-gal at a dose of 300 mg/ml/kg for one week. Behavioral analysis for depression and anxiety like symptoms were monitored by forced swim test (FST) and light/dark transition (LDT) test. Assessment of memory was done using the Morris water maze (MWM), passive avoidance test (PAT) and elevated plus maze (EPM) test. Biochemical analysis was done for estimation of antioxidant enzymes and acetylcholinesterase. Determination of brain biogenic amines was performed by HPLC-EC., Key Findings: Short term administration of D-gal significantly altered behavioral, biochemical and neurochemical responses in rats. D-Gal injected rats exhibited depressogenic and anxiogenic behaviors while memory was also significantly impaired in these rats. Brain lipid peroxidation and superoxide dismutase activity were significantly increased while catalase and glutathione peroxidase decreased. Increased activity of acetylcholinesterase was also exhibited by D-gal injected rats while brain biogenic amines were significantly decreased. Food intake and growth rate were however comparable in both groups., Significance: Together the behavioral, biochemical and neurochemical impairments following the high dose of D-gal suggest that symptoms similar to natural aging may be developed in rats in as early as one week., (Copyright © 2015 Elsevier Inc.

Cadmium is a toxic environmental and industrial pollutant. Cadmium toxicity has been reported to produce biochemical and behavioral dysfunction that may cause adverse effects on several organs including the central nervous system. The present study was designed to investigate the neurotoxic effects of Cadmium Chloride (CdCl2) at three different doses by using different behavioral models. Lipid peroxidation (LPO), superoxide dismutase (SOD) and acetylcholinesterase (AChE) activities were also monitored following acute intraperitoneal injection of cadmium. Twenty four adult locally bred Albino Wistar rats were divided into control and 3 test groups (n = 6). Control rats were injected intraperitoneally with saline (0.9% NaCl) and test groups were injected with CdCl2 (1 mg/kg, 2 mg/kg and 3 mg/kg) dissolved in physiological solution. Behavioral activities of rats were monitored after 1 h of cadmium injection. Locomotor activity and depression-like symptoms were measured by Open Field Test (OFT) and Forced Swimming Test (FST) respectively. Anxiety like behavior was monitored using Light-dark Transition (LDT) test and memory functions of rats were assessed by Morris Water Maze test (MWM). In the present study acute cadmium administration dose dependently increased anxiety in rats as compared to control rats. A significant increase in depression-like symptoms was also exhibited by cadmium treated rats. These behavioral dysfunctions may be attributed to the decreased superoxide dismutase (SOD) activity and simultaneously increased brain lipid peroxidation (LPO). Moreover learning and memory assessed by MWM showed dose dependent impairment in memory function in cadmium treated rats as compared to control rats. Acetylcholinesterase (AChE) activity was also decreased in brains of cadmium administered rats. It is suggested in this study that behavioral, biochemical and neurochemical dysfunctions caused by acute cadmium administration occur in a dose dependent manner.

Background: Atypical hemolytic uremic syndrome (aHUS) is a rare disease with a high recurrence rate after kidney transplantation. In most cases, aHUS are caused by genetic mutations of components of the complement alternative pathway. In this single-center series, we present our data of 12 consecutive patients with aHUS and the outcome after kidney transplantation., Methods: In this 10-year retrospective study, we identified 12 patients with aHUS who were managed in our center since 2003. We reviewed clinical data, including genetic testing, posttransplant course and response to therapy including the prophylactic use of eculizumab., Results: Overall, eight patients are women. Six of our patients have at least one genetic mutation causing aHUS, including 4 with complement factor H mutations. Nine patients had at least one previous kidney transplant that failed secondary to recurrent aHUS (75% of our patients). Three patients were treated with eculizumab and plasmapheresis for recurrent aHUS after kidney transplantation; two of them responded to the therapy. Four patients received prophylactic eculizumab; three of them received 6 months and one has been on life long therapy. No signs of recurrence have been observed in these 4 patients so far., Conclusion: Genetic mutations of the complement alternative pathway were confirmed in half of our patients, most of those mutations are in CHF. We demonstrate that treatment or prophylaxis with eculizumab was effective in reversing or preventing aHUS whether or not genetic complement mutations were identified.

A novel technique has been developed, which will open exciting new opportunities for studying the very neutron-rich nuclei involved in the r process. As a proof of principle, the γ spectra from the β decay of ^{76}Ga have been measured with the SuN detector at the National Superconducting Cyclotron Laboratory. The nuclear level density and γ-ray strength function are extracted and used as input to Hauser-Feshbach calculations. The present technique is shown to strongly constrain the ^{75}Ge(n,γ)^{76}Ge cross section and reaction rate.
