Functional connectivity MRI (fcMRI) studies of individuals currently diagnosed with major depressive disorder (MDD) document hyperconnectivities within the default mode network (DMN) and between the DMN and salience networks (SN) with regions of the cognitive control network (CCN). Studies of individuals in the remitted state are needed to address whether effects derive from trait, and not state or chronic burden features of MDD. fcMRI data from two 3.0 Tesla GE scanners were collected from 30 unmedicated (47% medication naïve) youth (aged 18-23, modal depressive episodes = 1, mean age of onset = 16.2, SD = 2.6) with remitted MDD (rMDD; modal years well = 4) and compared with data from 23 healthy controls (HCs) using four bilateral seeds in the DMN and SN (posterior cingulate cortex (PCC), subgenual anterior cingulate (sgACC), and amygdala), followed by voxel-based comparisons of the whole brain. Compared to HCs, rMDD youth exhibited hyperconnectivities from both PCC and sgACC seeds with lateral, parietal, and frontal regions of the CCN, extending to the dorsal medial wall. A factor analysis reduced extracted data and a PCC factor was inversely correlated with rumination among rMDD youth. Two factors from the sgACC hyperconnectivity clusters were related to performance in cognitive control on a Go/NoGo task, one positively and one inversely. Findings document hyperconnectivities of the DMN and SN with the CCN (BA 8/10), which were related to rumination and sustained attention. Given these cognitive markers are known predictors of response and relapse, hyperconnectivities may increase relapse risk or represent compensatory mechanisms.

Background Globally, disrespectful, and abusive childbirth practices negatively impact women’s health, create barriers to accessing health facilities, and contribute to poor birth experiences and adverse outcomes for both mothers and newborns. However, the degree to which disrespectful maternity care is associated with complications during childbirth is poorly understood, particularly in Ethiopia. Aim To determine the extent to which disrespectful maternity care is associated with maternal and neonatal-related complications in central Ethiopia. Methods A multicentre cross-sectional study was conducted in the West Shewa Zone of Oromia, Ethiopia. The sample size was determined using the single population proportion formula. Participants ( n  = 440) were selected with a simple random sampling technique using computer-generated random numbers. Data were collected through face-to-face interviews with a pretested questionnaire and were entered into Epidata and subsequently exported to STATA version 17 for the final analysis. Analyses included descriptive statistics and binary logistic regression, with a 95% confidence interval (CI) and an odds ratio (OR) of 0.05. Co-founders were controlled by adjusting for maternal sociodemographic characteristics. The primary exposure was disrespectful maternity care; the main outcomes were maternal and neonatal-related complications. Results Disrespectful maternity care was reported by 344 women (78.2%) [95% CI: 74–82]. Complications were recorded in one-third of mothers (33.4%) and neonates (30%). Disrespectful maternity care was significantly associated with maternal (AOR = 2.22, 95% CI: 1.29, 3.8) and neonatal-related complications (AOR = 2.78, 95% CI: 1.54, 5.04). Conclusion The World Health Organization advocates respectful maternal care during facility-based childbirth to improve the quality of care and outcomes. However, the findings of this study indicated high mistreatment and abuse during childbirth in central Ethiopia and a significant association between such mistreatment and the occurrence of both maternal and neonatal complications during childbirth. Therefore, healthcare professionals ought to prioritise respectful maternity care to achieve improved birth outcomes and alleviate mistreatment and abuse within the healthcare sector.

Background The core principles and key indicators of Respectful Maternity Care (RMC), particularly in low-income settings, are under-researched. Validated core principles and indicators are crucial for measuring RMC, especially in contexts where workforce shortages, infrastructure gaps, and sociocultural factors impact the care. Thus, this study aimed to identify and validate the core principles and indicators of RMC in resource-limited settings. Methods A three-round Delphi study was conducted. Maternity care professionals (midwives, educators, researchers, and obstetricians) based in Ethiopia ( n  = 33) were recruited via email through professional networks. Original peer-reviewed research published in English-language journals between 2010 and 2024 was reviewed and used to generate 75 initial indicators, which were securely uploaded to Qualtrics ® for digital distribution. The indicators were evaluated on a four-point Likert scale for importance, relevance, and clarity. Responses were analysed and reported back to the participants for round two. After analysing the second-round results, the final version was shared with the participants for the third round. The third round did not generate any new information or ideas. Participants were also invited to provide feedback and suggest additional core principles and indicators that they considered missing. Results In the first round, 75 indicators were assessed. The Item-level Content Validity Indexes ranged from 0.66 to 1.00 for importance and relevance, and 0.90 to 1.00 for clarity. The Scale-level Content Validity Index was 0.94 for importance and relevance and 0.98 for clarity. Three indicators were eliminated in round one; 12 were merged, and three remained unchanged. Two new indicators were added to the items. Thirteen core principles of RMC were proposed, and ten were accepted. Sixty indicators aligned with the ten core principles of RMC were finalised for round two. After round two, 11 indicators were removed, leading to a final list of 49 indicators. The third round generated no further revisions to the questionnaire. Conclusion The ten core principles and forty-nine indicators validated in this study provide a robust blueprint for the consistent implementation and monitoring of RMC. This validated framework also provides a timely, evidence-based response to the WHO’s call for the most valid and responsive RMC indicators in clinical settings. Future research should assess the core principles and indicators’ validity and reliability across diverse contexts.

Background Previous research examining the birth of the placenta has focussed on quantitative outcomes comparing active and expectant (physiological) management. However, it is also important to understand women’s experiences of birthing the placenta. Methods The participant group consisted of 11 women who had expectant management, eight who had active management and one who was unsure. Participants were interviewed in-depth and the data analysed using thematic analysis. Results Seven themes were identified in the data relating to before, during and after the birth of the placenta. Before birth themes focused on making decisions and included ‘doing the research’ and ‘natural birth’. During the birth of the placenta themes were ‘boundaries of time’, ‘focusing on baby’ and ‘sensations’. After the birth themes consisted of ‘looking’ and ‘keeping’. Conclusion Most of the women considered a physiological birth of the placenta to be an intrinsic element of natural birth. Active management was considered to be an intervention used if complications occurred. In contrast, women who chose active management did not consider the placenta to be an important element of natural birth, and chose active management in order to prevent complications. Decisions about birthing the placenta were informed by Internet sources and previous personal experiences rather than care providers. During the birth of the placenta care providers managed the boundaries of time whilst women focused on their baby. The sensations women described were consistent across both types of management. Women valued seeing their placenta and having the opportunity to keep it, and placenta encapsulation was popular. The findings of this study contribute the experiences of women to the body of knowledge informing practice during the birth of the placenta.

Here, we analyzed the fast-twitch muscle of juvenile Piaractus mesopotamicus (pacu) submitted to prolonged fasting (30d) and refeeding (6h, 24h, 48h and 30d). We measured the relative rate of weight and length increase (RRIlength and RRIweight), performed shotgun proteomic analysis and did Western blotting for PVALB after 30d of fasting and 30d of refeeding. We assessed the gene expression of igf-1, mafbx and pvalb after 30d of fasting and after 6h, 24h, 48h and 30d of refeeding. We performed a bioinformatic analysis to predict miRNAs that possibly control parvalbumin expression. After fasting, RRIlength, RRIweight and igf-1 expression decreased, while the mafbx expression increased, which suggest that prolonged fasting caused muscle atrophy. After 6h and 24h of refeeding, mafbx was not changed and igf-1 was downregulated, while after 48h of refeeding mafbx was downregulated and igf-1 was not changed. After 30d of refeeding, RRIlength and RRIweight were increased and igf-1 and mafbx expression were not changed. Proteomic analysis identified 99 proteins after 30d of fasting and 71 proteins after 30d of refeeding, of which 23 and 17, respectively, were differentially expressed. Most of these differentially expressed proteins were related to cytoskeleton, muscle contraction, and metabolism. Among these, parvalbumin (PVALB) was selected for further validation. The analysis showed that pvalb mRNA was downregulated after 6h and 24h of refeeding, but was not changed after 30d of fasting or 48h and 30d of refeeding. The Western blotting confirmed that PVALB protein was downregulated after 30d of fasting and 30d of refeeding. The downregulation of the protein and the unchanged expression of the mRNA after 30d of fasting and 30d of refeeding suggest a post-transcriptional regulation of PVALB. Our miRNA analysis predicted 444 unique miRNAs that may target pvalb. In conclusion, muscle atrophy and partial compensatory growth caused by prolonged fasting followed by refeeding affected the muscle proteome and PVALB expression.

Background Major Depressive Disorder (MDD) and anxiety disorders often co‐occur, with poorer treatment response and long‐term outcomes. However, little is known about the shared and distinct neural mechanisms of comorbid MDD and anxiety (MDD+Anx). This study examined how MDD and MDD+Anx differentially impact cognitive control. Methods Eighteen MDD, 29 MDD+Anx, and 54 healthy controls (HC) completed the Parametric Go/No‐Go (PGNG) during fMRI, including Target, Commission, and Rejection trials. Results MDD+Anx had more activation in the anterior dorsolateral prefrontal cortex, hippocampus, and caudate during Rejections, and inferior parietal lobule during correct Targets than MDD and HC. During Rejections HC had greater activation in a number of cognitive control regions compared to MDD; in the posterior cingulate compared to MDD+Anx; and in the fusiform gyrus compared to all MDD. During Commissions HC had greater activation in the right inferior frontal gyrus than all MDD. MDD had more activation in the mid‐cingulate, inferior parietal lobule, and superior temporal gyrus than MDD+Anx during Commissions. Conclusions Despite similar performance, MDD and MDD+Anx showed distinct differences in neural mechanisms of cognitive control in relation to each other, as well as some shared differences in relation to HC. The results were consistent with our hypothesis of hypervigilance in MDD+Anx within the cognitive control network, but inconsistent with our hypothesis that there would be greater engagement of salience and emotion network regions. Comorbidity of depression and anxiety may cause increased heterogeneity in study samples, requiring further specificity in detection and measurement of intermediate phenotypes and treatment Targets.

Background Vector-borne diseases are important public health issues and, consequently, in silico models that simulate them can be useful. The susceptible-infected-recovered (SIR) model simulates the population dynamics of an epidemic and can be easily adapted to vector-borne diseases, whereas the Hardy-Weinberg model simulates allele frequencies and can be used to study insecticide resistance evolution. The aim of the present study is to develop a coupled system that unifies both models, therefore enabling the analysis of the effects of vector population genetics on the population dynamics of an epidemic. Methods Our model consists of an ordinary differential equation system. We considered the populations of susceptible, infected and recovered humans, as well as susceptible and infected vectors. Concerning these vectors, we considered a pair of alleles, with complete dominance interaction that determined the rate of mortality induced by insecticides. Thus, we were able to separate the vectors according to the genotype. We performed three numerical simulations of the model. In simulation one, both alleles conferred the same mortality rate values, therefore there was no resistant strain. In simulations two and three, the recessive and dominant alleles, respectively, conferred a lower mortality. Results Our numerical results show that the genetic composition of the vector population affects the dynamics of human diseases. We found that the absolute number of vectors and the proportion of infected vectors are smaller when there is no resistant strain, whilst the ratio of infected people is larger in the presence of insecticide-resistant vectors. The dynamics observed for infected humans in all simulations has a very similar shape to real epidemiological data. Conclusion The population genetics of vectors can affect epidemiological dynamics, and the presence of insecticide-resistant strains can increase the number of infected people. Based on the present results, the model is a basis for development of other models and for investigating population dynamics.

We present neuroimaging markers of the remitted state of major depressive disorder (rMDD) during facial emotion perception in 84 individuals during fMRI. Participants comprised 47 individuals (aged 18–23) diagnosed with rMDD and 37 healthy controls (HCs). Participants classified emotional faces or animals (control condition) in the Facial Emotion Perception Test (FEPT) during fMRI. Behavioural performance on the FEPT did not differ significantly between groups. During fMRI, both groups demonstrated significant blood oxygen level-dependent (BOLD) activity in bilateral inferior frontal gyri for the faces minus animals (F−A) contrast. The rMDD group additionally showed BOLD activity during F−A in numerous regions, including the bilateral paracingulate gyri, middle temporal gyri and right amygdala. The rMDD group exhibited significantly greater activity than the HC group in regions including the bilateral middle temporal gyri and left superior frontal gyrus. Although the rMDD group did not manifest the behavioural performance deficits on facial emotion recognition tasks that have been observed in actively depressed individuals, the rMDD group nevertheless showed increased BOLD activity compared with never-depressed controls during F-A in multiple posterior brain regions, suggesting that persistent effects of illness or possible trait vulnerabilities may distinguish individuals with rMDD from never-depressed controls.

Objectives: Individuals with major depressive disorder (MDD) demonstrate poorer learning and memory skills relative to never-depressed comparisons (NDC). Previous studies report decreased volume and disrupted function of frontal lobes and hippocampi in MDD during memory challenge. However, it has been difficult to dissociate contributions of short-term memory and executive functioning to memory difficulties from those that might be attributable to long-term memory deficits. Methods: Adult males (MDD, n=19; NDC, n=22) and females (MDD, n=23; NDC, n=19) performed the Semantic List Learning Task (SLLT) during functional magnetic resonance imaging. The SLLT Encoding condition consists of 15 lists, each containing 14 words. After each list, a Distractor condition occurs, followed by cued Silent Rehearsal instructions. Post-scan recall and recognition were collected. Groups were compared using block (Encoding-Silent Rehearsal) and event-related (Words Recalled) models. Results: MDD displayed lower recall relative to NDC. NDC displayed greater activation in several temporal, frontal, and parietal regions, for both Encoding-Silent Rehearsal and the Words Recalled analyses. Groups also differed in activation patterns in regions of the Papez circuit in planned analyses. The majority of activation differences were not related to performance, presence of medications, presence of comorbid anxiety disorder, or decreased gray matter volume in MDD. Conclusions: Adults with MDD exhibit memory difficulties during a task designed to reduce the contribution of individual variability from short-term memory and executive functioning processes, parallel with decreased activation in memory and executive functioning circuits. Ecologically valid long-term memory tasks are imperative for uncovering neural correlates of memory performance deficits in adults with MDD. (JINS, 2016, 22, 412–425)
