Fathers' involvement in pregnancy and childbirth in Africa: an integrative systematic review.

BACKGROUND: As notions of masculinity evolve globally, it is important to understand their dimensions within geographic regions and life contexts. African men's involvement in their partners'pregnancy and childbirth has been explored to a limited extent in the peer-reviewed literature. This analysis provides a comprehensive examination of the existing literature on the diverse experiences of fathers across the African continent. AIM: This study aims to provide an overview of fathers' experience of involvement in their partners' pregnancies andchildbirth in Africa. METHODS: A systematic integrative literature review guided the process. The review comprised problem identification, literature search, data evaluation, data analysis and presentation of results. Systematic searches were conducted in the Cinahl, PubMed and Scopus databases. RESULTS: The search identified 70 articles of which 31, relating to 11 African countries, were used. Of these, 20 were qualitative, 9 were quantitative and 2 were mixed-methods studies. Men's alienation from health services, and traditional gender norms that discourage fathers' supportive role during pregnancy were prevalent themes. Financial pressures also dominated fathers'experiences. At the same time, in 18 studies fathers expressed motivation to be involved partners and supportive fathers, despite stigma and exclusion from maternity services. CONCLUSION: This integrative review shows that fathers' experiences of their involvement in their partners' pregnancy and childbirth across African countries are influenced by multiple factors. While unwelcoming health services, traditional gender norms, and low income are barriers to male involvement, education, younger age, and modern gender norms are associated with greater male involvement.

Main findings: There is a diversity of experiences among fathers across the African continent, with healthcare system alienation, influential gender norms, and financial pressure being common themes.Added knowledge: Unwelcoming health services, traditional gender norms, and low income were found to be impediments to male involvement in their partners' pregnancy and childbirth, while education, younger age, and modern gender norms were associated with greater male involvement.Global health impact for policy and action: Information and education for men and conducive healthcare environments would enable more positive experiences for men and encourage their greater involvement.

Increasing Pitch Count is Associated with Increasing Elbow Flexion Angle at Ball Release in Youth Baseball Pitchers.

BACKGROUND: Baseball is one of the most popular sports among youth athletes in the United States, and among these players, pitchers are at a particularly high risk of sustaining an injury. Overuse of the arm from repetitive pitching is a common mechanism for injury. Despite the attention that overuse injury has received, little is known regarding the mechanism that leads to elbow injury. This study aims to determine the effect of increasing pitch count on elbow flexion at ball release in a youth pitching cohort. The authors hypothesize that elbow flexion will increase as pitch count increases. METHODS: Study subjects included volunteers from youth baseball players from local teams and public advertisements. Retro-reflective markers attached to bony landmarks were placed on the players according to ISG recommendations. Pitchers threw an indoor simulated game. Three-dimensional marker trajectories were collected using a 12-camera optical motion capture system, and ball velocity was captured using a radar gun. Voluntary maximal isometric strength of the internal and external rotators was evaluated before and after pitching. Paired two-tailed t-tests were performed to determine if a significant change occurred between the fresh and fatigued sets. RESULTS: Twelve adolescent male pitchers were recruited. Eleven of 12 pitchers completed the prescribed 6 sets of 15 pitches, culminating in a 90-pitch simulated game. The ball speed in the second set was found to be the highest in all pitchers and was considered the "peak set" (p = .021) while ball speed was the slowest in the sixth set of pitches and was therefore considered the "fatigue set" (p = .001). There was a moderate but statistically significant inverse correlation between elbow flexion at ball release and maximum internal rotation velocity (p = .005). Elbow flexion at ball release was also significantly positively correlated with shoulder abduction at ball release (p = 0.004). Elbow flexion at ball release was not significantly correlated with ball velocity (p=.108). DISCUSSION: In a simulated game laboratory setting, increasing pitch count was associated with increasing elbow flexion angle at ball release in youth baseball pitchers. These findings demonstrate that pitching with fatigue may cause biomechanical changes that have been associated with increased rates of elbow injury in the adult throwing population. Further investigation on the association between elbow flexion angle and elbow injury in the youth baseball population is needed.

Diet-microbiome interactions promote enteric nervous system resilience following spinal cord injury.

Spinal cord injury (SCI) results in a plethora of physiological dysfunctions across all body systems, including intestinal dysmotility and atrophy of the enteric nervous system (ENS). Typically, the ENS has capacity to recover from perturbation, so it is unclear why intestinal pathophysiologies persist after traumatic spinal injury. With emerging evidence demonstrating SCI-induced alterations to the gut microbiome composition, we hypothesized that modulation of the gut microbiome could contribute to enteric nervous system recovery after injury. Here, we show that intervention with the dietary fiber, inulin prevents ENS atrophy and limits SCI-induced intestinal dysmotility in mice. However, SCI-associated microbiomes and exposure to specific SCI-sensitive gut microbes are not sufficient to modulate injury-induced intestinal dysmotility. Intervention with microbially-derived short-chain fatty acid (SCFA) metabolites prevents ENS dysfunctions and phenocopies inulin treatment in injured mice, implicating these microbiome metabolites in protection of the ENS. Notably, inulin-mediated resilience is dependent on signaling by the cytokine IL-10, highlighting a critical diet-microbiome-immune axis that promotes ENS resilience following SCI. Overall, we demonstrate that diet and microbially-derived signals distinctly impact recovery of the ENS after traumatic spinal injury. This protective diet-microbiome-immune axis may represent a foundation to uncover etiological mechanisms and future therapeutics for SCI-induced neurogenic bowel.

Microglia protect against age-associated brain pathologies.

Microglia are brain-resident macrophages that contribute to central nervous system (CNS) development, maturation, and preservation. Here, we examine the consequences of permanent microglial deficiencies on brain aging using the Csf1rΔFIRE/ΔFIRE mouse model. In juvenile Csf1rΔFIRE/ΔFIRE mice, we show that microglia are dispensable for the transcriptomic maturation of other brain cell types. By contrast, with advancing age, pathologies accumulate in Csf1rΔFIRE/ΔFIRE brains, macroglia become increasingly dysregulated, and white matter integrity declines, mimicking many pathological features of human CSF1R-related leukoencephalopathy. The thalamus is particularly vulnerable to neuropathological changes in the absence of microglia, with atrophy, neuron loss, vascular alterations, macroglial dysregulation, and severe tissue calcification. We show that populating Csf1rΔFIRE/ΔFIRE brains with wild-type microglia protects against many of these pathological changes. Together with the accompanying study by Chadarevian and colleagues1, our results indicate that the lifelong absence of microglia results in an age-related neurodegenerative condition that can be counteracted via transplantation of healthy microglia.

Challenges and opportunities of English as the medium of instruction in diploma midwifery programs in Bangladesh: a mixed-methods study.

BACKGROUND: English is generally recognized as the international language of science and most research on evidence-based medicine is produced in English. While Bangla is the dominant language in Bangladesh, public midwifery degree programs use English as the medium of instruction (EMI). This enables faculty and student access to the latest evidence-based midwifery content, which is essential for provision of quality care later. Yet, it also poses a barrier, as limited English mastery among students and faculty limits both teaching and learning. METHODS: This mixed-methods study investigates the challenges and opportunities associated with the implementation of EMI in the context of diploma midwifery education in Bangladesh. Surveys were sent to principals at 38 public midwifery education institutions, and 14 English instructors at those schools. Additionally, ten key informant interviews were held with select knowledgeable stakeholders with key themes identified. RESULTS: Surveys found that English instructors are primarily guest lecturers, trained in general or business English, without a standardized curriculum or functional English language laboratories. Three themes were identified in the key informant interviews. First, in addition to students' challenges with English, faculty mastery of English presented challenges as well. Second, language labs were poorly maintained, often non-functional, and lacked faculty. Third, an alternative education model, such as the English for Specific Purposes (ESP) curriculum,  has potential to strengthen English competencies within midwifery schools. CONCLUSIONS: ESP, which teaches English for application in a specific discipline, is one option available in Bangladesh for midwifery education. Native language instruction and the middle ground of multilingualism are also useful options. Although a major undertaking, investing in an ESP model and translation of technical midwifery content into relevant mother tongues may provide faster and more complete learning. In addition, a tiered system of requirements for English competencies tied to higher levels of midwifery education could build bridges to students to help them access global evidence-based care resources. Higher levels might emphasize English more heavily, while the diploma level would follow a multilingualism approach, teach using an ESP curriculum, and have complementary emphasis on the mother tongue.

A flow cytometric assay to detect viability and persistence of Salmonella enterica subsp. enterica serotypes in nuclease-free water at 4 and 25°C.

Salmonella spp. is one of the most isolated microorganisms reported to be responsible for human foodborne diseases and death. Water constitutes a major reservoir where the Salmonella spp. can persist and go undetected when present in low numbers. In this study, we assessed the viability of 12 serotypes of Salmonella enterica subsp. enterica for 160 days in nuclease-free water at 4 and 25°C using flow cytometry and Tryptic Soy Agar (TSA) plate counts. The results show that all 12 serotypes remain viable after 160 days in distilled water using flow cytometry, whereas traditional plate counts failed to detect ten serotypes incubated at 25°C. Moreover, the findings demonstrate that 4°C constitutes a more favorable environment where Salmonella can remain viable for prolonged periods without nutrients. Under such conditions, however, Salmonella exhibits a higher susceptibility to all tested antibiotics and benzalkonium chloride (BZK). The pre-enrichment with Universal Pre-enrichment Broth (UP) and 1/10 × Tryptic Soy broth (1/10 × TSB) resuscitated all tested serotypes on TSA plates, nevertheless cell size decreased after 160 days. Furthermore, phenotype microarray (PM) analysis of S. Inverness and S. Enteritidis combined with principal component analysis (PCA) revealed an inter-individual variability in serotypes with their phenotype characteristics, and the impact of long-term storage at 4 and 25°C for 160 days in nuclease-free water. This study provides an insight to Salmonella spp. long-term survivability at different temperatures and highlights the need for powerful tools to detect this microorganism to reduce the risk of disease transmission of foodborne pathogens via nuclease-free water.

AAV-BR1 does not target endothelial cells in Sprague Dawley rats unlike in mice.

Adeno-associated viruses (AAVs) are a popular tool in gene therapy approaches and have been engineered to specifically target different cells. There is interest in targeting endothelial cells (ECs) of the blood brain barrier and the AAV2 capsid variant BR1 has been found to transduce ECs with high selectivity in various mice models. However, this has not been tested in rat models. Here, we show that there is no EC transduction with systemic injection of the AAV-BR1-CAG-GFP virus in Sprague-Dawley rats (n=3), but instead transduction of brain parenchymal cells with neuronal morphology. These findings emphasize the importance of species-differences in use of AAVs.

Improving Healthcare Quality and Clinical Outcomes for Persons with Dementia in the Sub-Acute Hospital Through Person-Centered Care Practice.

Background: Person-centered care is considered beneficial for persons with dementia. Objective: To evaluate the impact of a person-centered knowledge translation intervention on the quality of healthcare and outcomes for persons with dementia. Methods: Over nine months, sub-acute hospital nursing, allied health, and medical staff (n = 90) participated in online and/or face-to-face person-centered education and were supported by senior nursing, allied health, and medical staff champions (n = 8) to implement person-centered healthcare. The quality of healthcare service, ward climate and care delivery were evaluated pre/post study intervention. In the week following hospital admission (Time 1) and week of discharge (Time 3), agitation incidence (co-primary outcome) was assessed in participants with dementia (n = 80). Participant delirium (co-primary outcome), accidents/injuries, psychotropic medicines, length of stay, readmission and discharge destination (secondary outcomes) were compared with a retrospective group (n = 77) matched on demographics, cognition and function in activities of daily living. Results: Improvements occurred post-intervention in service quality by 17.5% (p = 0.369, phi = 0.08), ward climate by 18.1% (p = 0.291, phi = 0.08), and care quality by 50% (p = 0.000, phi = 0.37). Participant agitation did not change from Time 1 to Time 3 (p = 0.223). Relative to the retrospective group, significant reductions occurred in participant delirium (p = 0.000, phi = 0.73), incidents/injuries (p = 0.000, phi = 0.99), psychotropic medicine use (p = 0.030, phi = 0.09), and hospital readmissions within 30 days (p = 0.002, phi = 0.25), but not in discharge to home (p = 0.171). Conclusions: When person-centered healthcare knowledge is translated through staff education and practice support, persons with dementia can experience improved healthcare services and clinical outcomes, while healthcare services can benefit through reductions in unplanned service use.

What matters to people and families affected by cerebral small vessel disease (SVD)? A qualitative grounded theory investigation.

Background: Cerebral small vessel disease (SVD) is a common neurological disorder contributing to stroke, dementia, and disability. No treatment options exist although clinical trials are ongoing. We aimed to understand what matters to people and families affected by SVD to inform future research. Methods: We thematically analysed unsolicited correspondences from members of the public addressed to members of the Edinburgh SVD Research Group on a variety of subjects related to SVD. We used inductive thematic codes, categorised under concerns, requests, emotions, and contributions, to form a grounded theory that categorised and ranked concerns raised. Results: 101 correspondents expressed 346 concerns between August 2015 and February 2021, mostly via email. 60 correspondents (59.4 %) disclosed a SVD diagnosis, 39 (38.6 %) disclosed a previous stroke or TIA, and 40 (39.6 %) were family of people living with SVD. Primary concerns related to cognitive problems (number of correspondents (n)=43 (42.6 %)), lack of support or information from healthcare services (n = 41 (40.6 %)), prognosis (n = 37 (36.6 %)), sensory disturbances (n = 27 (26.7 %)), functional problems (n = 24, (23.8 %)), impact on daily life (n = 24 (23.8 %)), and causes of SVD (n = 19 (18.8 %)). 57 correspondents (56.4 %) expressed support for research, 43 (42.6 %) expressed an eagerness to understand SVD, 35 (34.7 %) expressed helplessness, and 19 (18.8 %) expressed frustration. Conclusions: Cognitive decline was the main concern for people and families living with SVD who corresponded with the Edinburgh SVD research group. These findings also indicate a need for more accessible services and better information about SVD for patients and families.

Lessons from Peru to reduce under-5 mortality: understanding program implementation and context.

BACKGROUND: Health policymakers aiming to reduce under-5 mortality (U5M) often lack data regarding how successful interventions in other countries were implemented. The Exemplars in U5M Study identified countries that achieved significant reductions in amenable U5M. This case study in Peru used implementation research to explore the contextual factors and strategies that contributed to the successful implementation of key evidence-based interventions (EBIs). METHODS: This research utilized a hybrid implementation research framework and a mixed-methods approach to understand the factors associated with EBI implementation and the successful reduction of U5M between 2000-2015. A desk review of existing literature on EBIs and U5M in Peru was completed, and in-depth interviews were performed with key Peruvian informants to understand the implementation strategies employed and the contextual factors that facilitated or were barriers to success. For the purposes of this analysis, three EBIs were selected and evaluated: antenatal care visits (ANC), facility-based deliveries, and infant vaccination. RESULTS: Between 2000-2015, the percent of mothers attending at least four antenatal care visits rose from 69% to 96.9%, and the percent of facility-based deliveries increased from 56 to 91%. Three doses of the tetanus/diphtheria/pertussis vaccine, widely acknowledged as a key global health indicator, reached 90% by 2015. Key informants noted that economic growth, financial reforms, strong national commitment to reduce poverty in Peru, and national prioritization of maternal and child health, were important contextual factors that contributed to the successful reduction of U5M. They noted key strategies that helped achieve success during the implementation of EBIs, including utilization of data for decision-making, adaptation driven by cultural sensitivity to address gaps in coverage, and a focus on equity and anti-poverty initiatives with the participation of government, civil society, and political parties to assure continuity of policies. CONCLUSION: Several EBIs contributed to the successful reduction of U5M in Peru between 2000-2015. Strategies such as the focus on equity throughout the study period contributed to an increase in coverage of EBIs like ANC visits, facility-based deliveries and infant vaccination which worked to reduce U5M. Understanding how Peru successfully implemented programs that reduced preventable infant and child deaths could be useful to replicating this substantial public health success in other low- and middle-income countries.

Recognition of the Presence of Bone Fractures Through Physicochemical Changes in Diagenetic Bone.

Much research has focused on attempting to understand the drivers of bone diagenesis. However, this sensitive process is easily influenced by various factors, particularly the condition of the remains (i.e., whether they have been subjected to trauma). Previous research demonstrates that trauma can influence soft tissue decomposition, yet to date, no studies have looked at how bone fractures could affect bone diagenesis. To address this gap, two short timescale studies were conducted to investigate the influence of bone fractures on the physicochemical composition of disarticulated, partially fleshed animal remains. Disarticulated porcine bones were either fractured using blunt force or sharp force whilst fresh (producing perimortem damage), at 60 days producing postmortem damage (postmortem interval (PMI)), or left intact and left outside for up to 180 days post-fracture/240 days PMI. Retrieved bone sections were then analyzed for physicochemical differences using non-destructive methods, i.e., scanning electron microscopy energy dispersive spectroscopy and Fourier transform infrared spectroscopy with attenuated total reflectance. It was hypothesized that differences would be found in the physicochemical composition between the bones with fractures and those without after undergoing diagenetic change. The bone fractures significantly affected the elemental composition of bone over time, but structural composition initially remained stable. It was also possible to distinguish between perimortem and postmortem fractures using these two analytical techniques due to physicochemical differences. This research shows bone fractures can significantly alter the physicochemical composition of the bone during the postmortem period and have the potential to facilitate more accurate PMI estimations in forensic contexts.

AimSeg: A machine-learning-aided tool for axon, inner tongue and myelin segmentation.

Electron microscopy (EM) images of axons and their ensheathing myelin from both the central and peripheral nervous system are used for assessing myelin formation, degeneration (demyelination) and regeneration (remyelination). The g-ratio is the gold standard measure of assessing myelin thickness and quality, and traditionally is determined from measurements made manually from EM images-a time-consuming endeavour with limited reproducibility. These measurements have also historically neglected the innermost uncompacted myelin sheath, known as the inner tongue. Nonetheless, the inner tongue has been shown to be important for myelin growth and some studies have reported that certain conditions can elicit its enlargement. Ignoring this fact may bias the standard g-ratio analysis, whereas quantifying the uncompacted myelin has the potential to provide novel insights in the myelin field. In this regard, we have developed AimSeg, a bioimage analysis tool for axon, inner tongue and myelin segmentation. Aided by machine learning classifiers trained on transmission EM (TEM) images of tissue undergoing remyelination, AimSeg can be used either as an automated workflow or as a user-assisted segmentation tool. Validation results on TEM data from both healthy and remyelinating samples show good performance in segmenting all three fibre components, with the assisted segmentation showing the potential for further improvement with minimal user intervention. This results in a considerable reduction in time for analysis compared with manual annotation. AimSeg could also be used to build larger, high quality ground truth datasets to train novel deep learning models. Implemented in Fiji, AimSeg can use machine learning classifiers trained in ilastik. This, combined with a user-friendly interface and the ability to quantify uncompacted myelin, makes AimSeg a unique tool to assess myelin growth.

Exploring the Use of Living Shorelines for Stabilization and Nutrient Mitigation in New England.

As salt marsh habitats face challenges due to sea level rise, storm events, and coastal development, there is an effort to use nature-based approaches such as living shorelines to enhance salt marshes and provide coastal protection. A living shoreline restoration and seasonal monitoring was conducted between July 2016 and October 2018 at an eroding salt marsh on Martha's Vineyard, Massachusetts, Northeastern USA to assess changes in two essential ecosystem services: shoreline stabilization and nitrogen removal. Neither the living shoreline nor unaltered sites demonstrated significant sediment deposition at the marsh edge or on the marsh platform between 2017 and 2018. While we expected nitrogen removal via denitrification to improve at the living shoreline sites over time as abiotic and biotic conditions became more favorable, we found limited support for this hypothesis. We found higher rates of denitrification enzyme activity (DEA) at the living shoreline sites when compared to unaltered sites, but these rates did not increase over time. This study also provides a qualitative assessment of our living shoreline structural integrity through the years, particularly following storm events that greatly challenged our restoration efforts. We demonstrate that living shorelines fortified solely with natural materials may not be the most effective approach to maintain these ecosystem services for Northeastern USA salt marshes exposed to intense northeasterly storms. We suggest the restoration of salt marshes to improve major functions be a priority among managers and restoration practitioners. Initiatives promoting the use of nature-based restoration solution where environmental conditions permit should be encouraged.

Health System Strengthening Through Professional Midwives in Bangladesh: Best Practices, Challenges, and Successes.

In 2008, a cadre of professional midwives was introduced in Bangladesh. Since then, 120 midwifery educational programs have been established. There are 2,556 midwives serving at 667 government health facilities, and there are more midwives working in nongovernmental organizations and the private sector. This case study documents the process of establishing a midwifery profession with distinct midwifery expertise in Bangladesh and aims to guide other low- and middle-income countries in best practices and challenges. We describe the national administrative groundwork for the profession's launch, roll-out of an education program aligned with the International Confederation of Midwives, national deployment, enabling environments in deployment, and the professional association. Bangladesh's professional midwives' roles in humanitarian response and the COVID-19 pandemic are also discussed. The first and final authors were closely involved in supporting the government's establishment of the profession, and their direct experience is drawn upon to contextualize the topics. In addition, the authors conducted a desk review of documents that supported the profession's integration into the health system and documented its results. Both routine program data and existing research studies were reviewed. Outcomes show that midwives are deployed to 95% of government subdistrict hospitals. About 50% of these hospitals are fully staffed with 4 midwives, and within the hospitals, midwives are in charge of 90% of the maternity wards and attend 75%-85% of the births. Since the midwives' deployment, significant quality improvement for most World Health Organization indicators has been found, along with increases in service utilization. The experience of establishing a new midwifery profession in Bangladesh shows that it is possible for a lower middle-income country to introduce a globally standard midwifery profession, distinct from nursing, to improve quality sexual, reproductive, maternal, newborn, and adolescent health services in both humanitarian and development settings.

Midwife-led pandemic telemedicine services for maternal health and gender-based violence screening in Bangladesh: an implementation research case study.

BACKGROUND: The COVID-19 pandemic disrupted maternal and newborn health services in Bangladesh, exacerbating the large gaps in service utilization that existed prior to the pandemic. As part of its response, Bangladesh initiated remote antenatal and postnatal care telemedicine services led by midwives in 36 sub-district hospitals across five of Bangladesh's 64 districts. Gender-based violence screening and referral were integrated into the service to address a reported rise in violence following the country's pandemic lockdown. METHODS: Mixed-methods implementation research was used to develop an intrinsic case study describing the design and implementation of the telemedicine program. Qualitative analysis comprised document review, key informant interviews, and focus group discussions. Quantitative analysis employed an interrupted time series analysis with segmented multi-variate regression to compare maternity care service use trends before and after implementation. Poisson regression analysis was used to examine the trend in number of gender-based violence remote screenings, sessions held, and cases identified. RESULTS: A statistically significant change in trend for onsite antenatal and postpartum care as well as women seeking care at the hospital as a result of postpartum hemorrhage arising in the community was observed following the introduction of telemedicine. Facility births and cases of eclampsia appropriately identified and managed also had significant increases. In addition, over 6917 women were screened for GBV, 223 received counseling and 34 referrals were made, showing a statistically significant increase in frequency over time following the implementation of the telemedicine program. Challenges included that not all midwives adopted GBV screening, some women were reluctant to discuss GBV, there was an unanticipated need to introduce a patient visit scheduling system in all intervention hospitals, and many women were not reachable by phone due to lack of access or network coverage. CONCLUSIONS: Maternal health and gender-based violence telemedicine led by midwives was an effective, low-cost intervention in Bangladesh for addressing pandemic and pre-pandemic gaps in service use. Other low and middle-income countries planning to implement remote maternal health interventions via midwives should consider whether a patient visit scheduling system needs to be introduced, as well as limitations around mobile phone access and connectivity. Future research should include care quality oversight and improvement, and a more well-informed strategy for facilitating effective GBV screening.

To support the continuation of sexual and reproductive health services following pandemic lockdowns, Bangladesh introduced a midwife-led telemedicine program. Through the program, midwives who were already employed within the health system delivered remote antenatal and postnatal care, including gender-based violence screening and referral. The program operated in 36 sub-district hospitals across five of Bangladesh's 64 districts. Intrinsic implementation research was used to develop a case study describing the design and implementation of the telemedicine program. Qualitative and quantitative methods comprised document review, key informant interviews, focus group discussions, and service use trends. Analysis of the data identified a statistically significant trend increase for most maternity care services. Although they did increase significantly over time, referrals for GBV were less than expected, which may have been related to some midwives not screening for GBV, and/or that many women were reluctant to discuss GBV. In addition, there was an unanticipated need to introduce a patient visit scheduling system in all intervention hospitals, and many women were not reachable by phone due to lack of access or network coverage. In spite of this, 6197 women were screened for GBV. Of those, 223 received counseling and 34 received referrals. Overall, telemedicine led by midwives was an effective, low-cost intervention for maternal health, and a step toward stronger GBV response in Bangladesh. Other low and middle-income countries planning to implement remote maternal health interventions via midwives should consider what is needed to facilitate comfort for both providers and women as related to GBV screening, as well as practical issues regarding introducing scheduling systems and limitations of mobile phone access and connectivity.

Astrocyte-oligodendrocyte interaction regulates central nervous system regeneration.

Failed regeneration of myelin around neuronal axons following central nervous system damage contributes to nerve dysfunction and clinical decline in various neurological conditions, for which there is an unmet therapeutic demand. Here, we show that interaction between glial cells - astrocytes and mature myelin-forming oligodendrocytes - is a determinant of remyelination. Using in vivo/ ex vivo/ in vitro rodent models, unbiased RNA sequencing, functional manipulation, and human brain lesion analyses, we discover that astrocytes support the survival of regenerating oligodendrocytes, via downregulation of the Nrf2 pathway associated with increased astrocytic cholesterol biosynthesis pathway activation. Remyelination fails following sustained astrocytic Nrf2 activation in focally-lesioned male mice yet is restored by either cholesterol biosynthesis/efflux stimulation, or Nrf2 inhibition using the existing therapeutic Luteolin. We identify that astrocyte-oligodendrocyte interaction regulates remyelination, and reveal a drug strategy for central nervous system regeneration centred on targeting this interaction.

First in Human Subjects Testing of the UroMonitor: A Catheter-free Wireless Ambulatory Bladder Pressure Monitor.

PURPOSE: Urodynamics is the standard method of diagnosing bladder dysfunction, but involves catheters and retrograde bladder filling. With these artificial conditions, urodynamics cannot always reproduce patient complaints. We have developed a wireless, catheter-free intravesical pressure sensor, the UroMonitor, which enables catheter-free telemetric ambulatory bladder monitoring. The purpose of this study was twofold: to evaluate accuracy of UroMonitor pressure data, and assess safety and feasibility of use in humans. MATERIALS AND METHODS: Eleven adult female patients undergoing urodynamics for overactive bladder symptoms were enrolled. After baseline urodynamics, the UroMonitor was transurethrally inserted into the bladder and position was confirmed cystoscopically. A second urodynamics was then performed with the UroMonitor simultaneously transmitting bladder pressure. Following removal of urodynamics catheters, the UroMonitor transmitted bladder pressure during ambulation and voiding in private. Visual analogue pain scales (0-5) were used to assess patient discomfort. RESULTS: The UroMonitor did not significantly alter capacity, sensation, or flow during urodynamics. The UroMonitor was also easily inserted and removed in all subjects. The UroMonitor reproduced bladder pressure, capturing 98% (85/87) of voiding and nonvoiding urodynamic events. All subjects voided with only the UroMonitor in place with low post-void residual volume. Median ambulatory pain score with the UroMonitor was rated 0 (0-2). There were no post-procedural infections or changes to voiding behavior. CONCLUSIONS: The UroMonitor is the first device to enable catheter-free telemetric ambulatory bladder pressure monitoring in humans. The UroMonitor appears safe and well tolerated, does not impede lower urinary tract function, and can reliably identify bladder events compared to urodynamics.
