Women's experience of childbirth care in health facilities:a qualitative assessment of respectful maternity care in Afghanistan
BACKGROUND: Respectful maternity care (RMC) remains a key challenge in Afghanistan, despite progress on improving maternal and newborn health during 2001-2021. A qualitative study was conducted in 2018 to provide evidence on the situation of RMC in health facilities in Afghanistan. The results are useful to inform strategies to provide RMC in Afghanistan in spite of the humanitarian crisis due to Taliban's takeover in 2021.METHODS: Focus group discussions were conducted with women (4 groups, 43 women) who had used health facilities for giving birth and with providers (4 groups, 21 providers) who worked in these health facilities. Twenty key informant interviews were conducted with health managers and health policy makers. Motivators for, deterrents from using, awareness about and experiences of maternity care in health facilities were explored.RESULTS: Women gave birth in facilities for availability of maternity care and skilled providers, while various verbal and physical forms of mistreatment were identified as deterrents from facility use by women, providers and key informants. Low awareness, lack of resources and excessive workload were identified among the reasons for violation of RMC.CONCLUSION: Violation of RMC is unacceptable. Awareness of women and providers about the rights of women to respectful maternity care, training of providers on the subject, monitoring of care to prevent mistreatment, and conditioning any future technical and financial assistance to commitments to RMC is recommended.</p
Quality of caesarean delivery services and documentation in first-line referral facilities in Afghanistan: a chart review
<p>Abstract</p> <p>Background</p> <p>Increasing appropriate use and documentation of caesarean section (CS) has the potential to decrease maternal and perinatal mortality in settings with low CS rates. We analyzed data collected as part of a comprehensive needs assessment of emergency obstetric and newborn care (EmONC) facilities in Afghanistan to gain a greater understanding of the clinical indications, timeliness, and outcomes of CS deliveries.</p> <p>Methods</p> <p>Records were reviewed at 78 government health facilities expected to function as EmONC providers that were located in secure areas of the country. Information was collected on the three most recent CS deliveries in the preceding 12 months at facilities with at least one CS delivery in the preceding three months. After excluding 16 facilities with no recent CS deliveries, the sample includes 173 CS deliveries at 62 facilities.</p> <p>Results</p> <p>No CS deliveries were performed in the previous three months at 21% of facilities surveyed; all of these were lower-level facilities. Most CS deliveries (88%) were classified as emergencies, and only 12% were referrals from another facility. General anesthesia was used in 62% of cases, and spinal or epidural anesthesia in 34%. Only 28% of cases were managed with a partograph. Surgery began less than one hour after the decision for a CS delivery in just 30% of emergency cases. Among the 173 cases, 27 maternal deaths, 28 stillbirths, and 3 early neonatal deaths were documented. In cases of maternal and fetal death, the most common indications for CS delivery were placenta praevia or abruption and malpresentation. In 62% of maternal deaths, the fetus was stillborn or died shortly after birth. In 48% of stillbirths, the fetus had a normal heart rate at the last check. Information on partograph use was missing in 38% of cases, information on parity missing in 23% of cases and indications for cesareans missing in 9%.</p> <p>Conclusions</p> <p>Timely referral within and to EmONC facilities would decrease the proportion of CS deliveries that develop to emergency status. While the substantial mortality associated with CS in Afghanistan may be partly due to women coming late for obstetric care, efforts to increase the availability and utilization of CS must also focus on improving the quality of care to reduce mortality. Key goals should be encouraging use of partographs and improving decision-making and documentation around CS deliveries.</p
Readiness of emergency obstetric and newborn care in public health facilities in Afghanistan between 2010 and 2016
OBJECTIVE: To assess changes in readiness to provide emergency obstetric and newborn care (EmONC) in health facilities in Afghanistan between 2010 and 2016. METHODS: A secondary analysis was performed of a subset of data from cross-sectional health facility assessments conducted in December 2009 to February 2010 and May 2016 to January 2017. Interviews with health providers, facility inventory, and record review were conducted in both assessments. Descriptive statistics and Ï2 tests were used to compare readiness of EmONC at 59 public health facilities expected to provide comprehensive EmONC. RESULTS: The proportion of facilities reporting provision of uterotonic drugs, anticonvulsants, parenteral antibiotics, newborn resuscitation, and cesarean delivery did not change significantly between 2010 and 2016. Provision of assisted vaginal deliveries increased from 78% in 2010 to 98% in 2016 (P<0.001). Fewer health facilities had amoxicillin (61% in 2016 vs 90% in 2010; P<0.001) and gentamicin (74% in 2016 vs 95% in 2010; P<0.002). The number of facilities with at least one midwife on duty 24 hours a day/7 days a week significantly declined (88% in 2016 vs 98% in 2010; P=0.028). CONCLUSION: Despite a few positive changes, readiness of EmONC services in Afghanistan in 2016 had declined from 2010 levels
Mean first-passage time of quantum transition processes
In this paper, we consider the problem of mean first-passage time (MFPT) in
quantum mechanics; the MFPT is the average time of the transition from a given
initial state, passing through some intermediate states, to a given final state
for the first time. We apply the method developed in statistical mechanics for
calculating the MFPT of random walks to calculate the MFPT of a transition
process. As applications, we (1) calculate the MFPT for multiple-state systems,
(2) discuss transition processes occurring in an environment background, (3)
consider a roundabout transition in a hydrogen atom, and (4) apply the approach
to laser theory.Comment: 11 pages, no figur
Factors regulating the relationship between total and size-fractionated chlorophyll-a in coastal waters of the Red Sea
This is the final version. Available from the publisher via the DOI in this record.Phytoplankton biomass and size structure are recognized as key ecological indicators.
With the aim to quantify the relationship between these two ecological indicators in
tropical waters and understand controlling factors, we analyzed the total chlorophyll-a
concentration, a measure of phytoplankton biomass, and its partitioning into three
size classes of phytoplankton, using a series of observations collected at coastal
sites in the central Red Sea. Over a period of 4 years, measurements of flow
cytometry, size-fractionated chlorophyll-a concentration, and physical-chemical variables
were collected near Thuwal in Saudi Arabia. We fitted a three-component model
to the size-fractionated chlorophyll-a data to quantify the relationship between
total chlorophyll and that in three size classes of phytoplankton [pico- (<2”m),
nano- (2â20”m) and micro-phytoplankton (>20”m)]. The model has an advantage over
other more empirical methods in that its parameters are interpretable, expressed as
the maximum chlorophyll-a concentration of small phytoplankton (pico- and combined
pico-nanophytoplankton, C
m
p
and C
m
p,n
, respectively) and the fractional contribution of
these two size classes to total chlorophyll-a as it tends to zero (Dp and Dp,n). Residuals
between the model and the data (model minus data) were compared with a range of
other environmental variables available in the dataset. Residuals in pico- and combined
pico-nanophytoplankton fractions of total chlorophyll-a were significantly correlated with
water temperature (positively) and picoeukaryote cell number (negatively). We conducted
a running fit of the model with increasing temperature and found a negative relationship
between temperature and parameters C
m
p
and C
m
p,n
and a positive relationship between
temperature and parameters Dp and Dp,n. By harnessing the relative red fluorescence
of the flow cytometric data, we show that picoeukaryotes, which are higher in cell
number in winter (cold) than summer (warm), contain higher chlorophyll per cell than other
picophytoplankton and are slightly larger in size, possibly explaining the temperature
shift in model parameters, though further evidence is needed to substantiate this

finding. Our results emphasize the importance of knowing the water temperature and
taxonomic composition of phytoplankton within each size class when understanding their
relative contribution to total chlorophyll. Furthermore, our results have implications for the
development of algorithms for inferring size-fractionated chlorophyll from satellite data,
and for how the partitioning of total chlorophyll into the three size classes may change in

Temperature Responses of Heterotrophic Bacteria in Co-culture With a Red Sea Synechococcus Strain
Interactions between autotrophic and heterotrophic bacteria are fundamental for marine biogeochemical cycling. How global warming will affect the dynamics of these essential microbial players is not fully understood. The aims of this study were to identify the major groups of heterotrophic bacteria present in a Synechococcus culture originally isolated from the Red Sea and assess their joint responses to experimental warming within the metabolic ecology framework. A co-culture of Synechococcus sp. RS9907 and their associated heterotrophic bacteria, after determining their taxonomic affiliation by 16S rRNA gene sequencing, was acclimated and maintained in the lab at different temperatures (24â34°C). The abundance and cellular properties of Synechococcus and the three dominant heterotrophic bacterial groups (pertaining to the genera Paracoccus, Marinobacter, and Muricauda) were monitored by flow cytometry. The activation energy of Synechococcus, which grew at 0.94â1.38 dâ1, was very similar (0.34 ± 0.02 eV) to the value hypothesized by the metabolic theory of ecology (MTE) for autotrophs (0.32 eV), while the values of the three heterotrophic bacteria ranged from 0.16 to 1.15 eV and were negatively correlated with their corresponding specific growth rates (2.38â24.4 dâ1). The corresponding carrying capacities did not always follow the inverse relationship with temperature predicted by MTE, nor did we observe a consistent response of bacterial cell size and temperature. Our results show that the responses to future ocean warming of autotrophic and heterotrophic bacteria in microbial consortia might not be well described by theoretical universal rules
Quality of care in prevention, detection and management of postpartum hemorrhage in hospitals in Afghanistan:an observational assessment
Background: Hemorrhage is the leading cause of maternal mortality worldwide and accounts for 56% of maternal deaths in Afghanistan. Postpartum hemorrhage (PPH) is commonly caused by uterine atony, genital tract trauma, retained placenta, and coagulation disorders. The purpose of this study is to examine the quality of prevention, detection and management of PPH in both public and private hospitals in Afghanistan in 2016, and compare the quality of care in district hospitals with care in provincial, regional, and specialty hospitals. Methods: This study uses a subset of data from the 2016 Afghanistan National Maternal and Newborn Health Quality of Care Assessment. It covers a census of all accessible public hospitals, including 40 district hospitals, 27 provincial hospitals, five regional hospitals, and five specialty hospitals, as well as 10 purposively selected private hospitals. Results: All public and private hospitals reported 24 h/7 days a week service provision. Oxytocin was available in 90.0% of district hospitals, 89.2% of provincial, regional and specialty hospitals and all 10 private hospitals; misoprostol was available in 52.5% of district hospitals, 56.8% of provincial, regional and specialty hospitals and in all 10 private hospitals. For prevention of PPH, 73.3% women in district hospitals, 71.2% women at provincial, regional and specialty hospitals and 72.7% women at private hospital received uterotonics. Placenta and membranes were checked for completeness in almost half of women in all hospitals. Manual removal of placenta was performed in 97.8% women with retained placenta. Monitoring blood loss during the immediate postpartum period was performed in 48.4% of women in district hospitals, 36.9% of women in provincial, regional and specialty hospitals, and 43.3% in private hospitals. The most commonly observed cause of PPH was retained placenta followed by genital tract trauma and uterine atony. Conclusion: Gaps in performance of skilled birth attendants are substantial across public and private hospitals. Improving and retaining skills of health workers through on-site, continuous capacity development approaches and encouraging a culture of audit, learning and quality improvement may address clinical gaps and improve quality of PPH prevention, detection and management
Metastatic collecting duct carcinoma of the kidney treated with sunitinib
Collecting duct carcinoma (CDC) of the kidney is a rare and aggressive malignant tumor arising from the distal collecting tubules which has been shown to have a poor response to several kinds of systemic therapy. We present a case of metastatic CDC that responded favorably to a multiple tyrosine kinase inhibitor, sunitinib, achieving a partial response in both lung and skeletal metastases. To our knowledge, this is the first report showing therapeutic activity of sunitinib against CDC. Considering these findings, it would be worthwhile prospectively investigating the role of multiple tyrosine kinase inhibitors, particularly sunitinib, in the management of metastatic CDC
Quality of care in early detection and management of pre-eclampsia/eclampsia in health facilities in Afghanistan
BackgroundAfghanistan faces a high burden of maternal and neonatal morbidity and mortality. Hypertensive disorders of pregnancy, including pre-eclampsia and eclampsia (PE/E), are among the most common causes of maternal and neonatal complications. Hypertensive disorders of pregnancy can lead to fatal complications for both the mother and fetus. The 2016 Afghanistan National Maternal and Newborn Health Quality of Care Assessment assessed quality of early detection and management of PE/E in health facilities and skilled birth attendants' (SBAs) perceptions of their working environment.MethodsAll accessible public health facilities with an average of at least five births per day (n=77), a nationally representative sample of public health facilities with less than five births per day (n=149), and 20 purposively selected private health facilities were assessed. Methods included a facility inventory and record review, interviews with SBAs, and direct clinical observation of antenatal care (ANC), intrapartum care and immediate postnatal care (PNC), as well as severe PE/E case management.ResultsMost facilities had supplies and medicines for early detection and management of PE/E.At public health facilities, 357 of 414 (86.2%) clients observed during ANC consultations had their blood pressure checked and 159 (38.4%) were asked if they had experienced symptoms of PE/E. Only 553 of 734 (72.6%) SBAs interviewed were able to correctly identify severe pre-eclampsia described in a case scenario. Of 29 PE/E cases observed, 17 women (59%) received the correct loading dose of magnesium sulfate (MgSO4) and 12 women (41%) received the correct maintenance dose of MgSO4.At private health facilities, 39 of 45 ANC clients had their blood pressure checked and 9 of 45 (20%) were asked about symptoms of PE/E. Fifty-four of 64(84.4%) SBAs in private facilities correctly identified severe pre-eclampsia described in a case scenario.ConclusionNotable gaps in SBAs' knowledge and clinical practices in detection and management of PE/E in various health facilities increase the risk of maternal and perinatal mortality. Continuing education of health care providers and increased investment in focused quality improvement initiatives will be critical to improve the quality of health care services in Afghanistan
Brain mapping in cognitive disorders: a multidisciplinary approach to learning the tools and applications of functional neuroimaging
<p>Abstract</p> <p>Background</p> <p>With rapid advances in functional imaging methods, human studies that feature functional neuroimaging techniques are increasing exponentially and have opened a vast arena of new possibilities for understanding brain function and improving the care of patients with cognitive disorders in the clinical setting. There is a growing need for medical centers to offer clinically relevant functional neuroimaging courses that emphasize the multifaceted and multidisciplinary nature of this field. In this paper, we describe the implementation of a functional neuroimaging course focusing on cognitive disorders that might serve as a model for other medical centers. We identify key components of an active learning course design that impact student learning gains in methods and issues pertaining to functional neuroimaging that deserve consideration when optimizing the medical neuroimaging curriculum.</p> <p>Methods</p> <p>Learning gains associated with the course were assessed using polychoric correlation analysis of responses to the SALG (Student Assessment of Learning Gains) instrument.</p> <p>Results</p> <p>Student gains in the functional neuroimaging of cognition as assessed by the SALG instrument were strongly associated with several aspects of the course design.</p> <p>Conclusion</p> <p>Our implementation of a multidisciplinary and active learning functional neuroimaging course produced positive learning outcomes. Inquiry-based learning activities and an online learning environment contributed positively to reported gains. This functional neuroimaging course design may serve as a useful model for other medical centers.</p
