Expanded prenatal phenotype of ALG12-associated congenital disorder of glycosylation including bilateral multicystic kidneys.

Congenital disorders of glycosylation (CDG) are a group of rare autosomal recessive genetic disorders caused by pathogenic variants in genes coding for N-glycosylated glycoproteins, which play a role in folding, degrading, and transport of glycoproteins in their pathway. ALG12-CDG specifically is caused by biallelic pathogenic variants in ALG12. Currently reported features of ALG12-CDG include: developmental delay, hypotonia, failure to thrive and/or short stature, brain anomalies, recurrent infections, hypogammaglobulinemia, coagulation abnormalities, and genitourinary abnormalities. In addition, skeletal abnormalities resembling a skeletal dysplasia including shortened long bones and talipes equinovarus have been seen in more severe neonatal presentation of this disorder. We report on a case expanding the phenotype of ALG12-CDG to include bilateral, multicystic kidneys in a neonatal demise identified with homozygous pathogenic variants in the ALG12 gene at c.1001del (p.N334Tfs*15) through clinical trio exome sequencing.

Association of Age, Frailty, and Strategy for Initiation of Renal-Replacement Therapy: A Post Hoc analysis of the STARRT-Acute Kidney Injury Trial.

INTRODUCTION: This study was designed to assess the association of age and frailty with clinical outcomes in patients with severe acute kidney injury (AKI), according to accelerated and standard renal-replacement therapy (RRT) initiation strategies in the STARRT-AKI trial. METHODS: This was a secondary analysis of an international randomized trial. Older age was defined as ≥65 years. Frailty was assessed using the clinical frailty scale (CFS) score and defined as a score ≥5. The primary outcome was all-cause mortality at 90 days. Secondary outcomes included RRT dependence and RRT-free days at 90 days. We used logistic and linear regression and interaction testing to explore the impact of age and frailty on clinical outcomes. RESULTS: Of 2,927 patients randomized in the STARRT-AKI trial, 1,616 (55.2%) were aged ≥65 years (median [interquartile range] 73.9 [69.4-78.9]). Older patients had greater comorbid cardiovascular and chronic kidney disease, were more likely to be surgical admissions and to receive vasopressors at baseline. Older patients had higher 90-day mortality (50.4% vs. 35.6%, adjusted-odds ratio (OR), 1.81 [1.53-2.13], p < 0.001). There was no significant difference in RRT dependence at 90 days between older and younger patients (8.7% vs. 7.8%, adjusted-OR, 1.21 [0.82-1.79], p = 0.325). Patients with frailty had higher mortality; but no difference in RRT dependence at 90 days. There was no significant interaction between age and CFS score in relation to mortality, RRT dependence at 90 days, and other secondary outcomes. There was no significant difference in the proportion of patients who received RRT in the standard-strategy stratified by age groups (adjusted-OR, 0.85 [0.67-1.08], p = 0.180). CONCLUSION: In this secondary analysis of the STARRT-AKI trial, older and frail patients had higher mortality at 90 days; however, there was no difference in RRT dependence. Mortality and RRT dependence were not modified by RRT initiation strategy in older or frail patients.

Digital Physical Activity and Exercise Interventions for People Living with Chronic Kidney Disease: A Systematic Review of Health Outcomes and Feasibility.

Physical activity is essential to interrupt the cycle of deconditioning associated with chronic kidney disease (CKD). However, access to targeted physical activity interventions remain under-supported due to limited funding and specialised staff. Digital interventions may address some of these factors. This systematic review sought to examine the evidence base of digital interventions focused on promoting physical activity or exercise and their effect on health outcomes for people living with CKD. Electronic databases (PubMed, CINAHL, Embase, Cochrane) were searched from 1 January 2000 to 1 December 2023. Interventions (smartphone applications, activity trackers, websites) for adults with CKD (any stage, including transplant) which promoted physical activity or exercise were included. Study quality was assessed, and a narrative synthesis was conducted. Of the 4057 records identified, eight studies (five randomised controlled trials, three single-arm studies) were included, comprising 550 participants. Duration ranged from 12-weeks to 1-year. The findings indicated acceptability and feasibility were high, with small cohort numbers and high risk of bias. There were inconsistent measures of physical activity levels, self-efficacy, body composition, physical function, and psychological outcomes which resulted in no apparent effects of digital interventions on these domains. Data were insufficient for meta-analysis. The evidence for digital interventions to promote physical activity and exercise for people living with CKD is limited. Despite popularity, there is little evidence that current digital interventions yield the effects expected from traditional face-to-face interventions. However, 14 registered trials were identified which may strengthen the evidence-base.

Timing of Initiation of Renal-Replacement Therapy in Acute Kidney Injury.

BACKGROUND: Acute kidney injury is common in critically ill patients, many of whom receive renal-replacement therapy. However, the most effective timing for the initiation of such therapy remains uncertain. METHODS: We conducted a multinational, randomized, controlled trial involving critically ill patients with severe acute kidney injury. Patients were randomly assigned to receive an accelerated strategy of renal-replacement therapy (in which therapy was initiated within 12 hours after the patient had met eligibility criteria) or a standard strategy (in which renal-replacement therapy was discouraged unless conventional indications developed or acute kidney injury persisted for >72 hours). The primary outcome was death from any cause at 90 days. RESULTS: Of the 3019 patients who had undergone randomization, 2927 (97.0%) were included in the modified intention-to-treat analysis (1465 in the accelerated-strategy group and 1462 in the standard-strategy group). Of these patients, renal-replacement therapy was performed in 1418 (96.8%) in the accelerated-strategy group and in 903 (61.8%) in the standard-strategy group. At 90 days, death had occurred in 643 patients (43.9%) in the accelerated-strategy group and in 639 (43.7%) in the standard-strategy group (relative risk, 1.00; 95% confidence interval [CI], 0.93 to 1.09; P = 0.92). Among survivors at 90 days, continued dependence on renal-replacement therapy was confirmed in 85 of 814 patients (10.4%) in the accelerated-strategy group and in 49 of 815 patients (6.0%) in the standard-strategy group (relative risk, 1.74; 95% CI, 1.24 to 2.43). Adverse events occurred in 346 of 1503 patients (23.0%) in the accelerated-strategy group and in 245 of 1489 patients (16.5%) in the standard-strategy group (P<0.001). CONCLUSIONS: Among critically ill patients with acute kidney injury, an accelerated renal-replacement strategy was not associated with a lower risk of death at 90 days than a standard strategy.

Hemorrhagic Stroke in Pregnancy.

Hemorrhagic stroke carries a high risk of disability and mortality. The obstetrical population is at increased risk. Prompt diagnosis and maternal stabilization with a multidisciplinary approach are the mainstays in management. Computed tomography head is the diagnostic imaging of choice and is considered safe in pregnancy. Fetal status optimization before neurosurgery and delivery should be considered if the fetus is viable or if worsening maternal condition. Obstetric indications guide the mode of delivery. Cesarean delivery may be indicated to reduce increasing intracranial pressure. Neuraxial anesthesia should be considered to minimize catecholamine surges, reduce sedation, and control blood pressures.

Folate regulates RNA m5C modification and translation in neural stem cells.

BACKGROUND: Folate is an essential B-group vitamin and a key methyl donor with important biological functions including DNA methylation regulation. Normal neurodevelopment and physiology are sensitive to the cellular folate levels. Either deficiency or excess of folate may lead to neurological disorders. Recently, folate has been linked to tRNA cytosine-5 methylation (m5C) and translation in mammalian mitochondria. However, the influence of folate intake on neuronal mRNA m5C modification and translation remains largely unknown. Here, we provide transcriptome-wide landscapes of m5C modification in poly(A)-enriched RNAs together with mRNA transcription and translation profiles for mouse neural stem cells (NSCs) cultured in three different concentrations of folate. RESULTS: NSCs cultured in three different concentrations of folate showed distinct mRNA methylation profiles. Despite uncovering only a few differentially expressed genes, hundreds of differentially translated genes were identified in NSCs with folate deficiency or supplementation. The differentially translated genes induced by low folate are associated with cytoplasmic translation and mitochondrial function, while the differentially translated genes induced by high folate are associated with increased neural stem cell proliferation. Interestingly, compared to total mRNAs, polysome mRNAs contained high levels of m5C. Furthermore, an integrative analysis indicated a transcript-specific relationship between RNA m5C methylation and mRNA translation efficiency. CONCLUSIONS: Altogether, our study reports a transcriptome-wide influence of folate on mRNA m5C methylation and translation in NSCs and reveals a potential link between mRNA m5C methylation and mRNA translation.

Effect of kidney disease on all-cause and cardiovascular mortality in patients undergoing coronary angiography.

Acute kidney injury (AKI) occurred in 12.8% of patients undergoing surgery and is associated with increased mortality. Chronic kidney disease (CKD) is a well-known risk for death and cardiovascular disease (CVD). Effects of AKI and CKD on patients undergoing coronary angiography (CAG) remain incompletely defined. The aim of our study was to investigate the relationship between acute and CKD and mortality in patients undergoing CAG. The cohort study included 49,194 patients in the multicenter cohort from January 2007 to December 2018. Cox regression analyses and Fine-Gray proportional subdistribution risk regression analysis are used to examine the association between kidney disease and all-cause and cardiovascular mortality. In the present study, 13,989 (28.4%) patients had kidney disease. During follow-up, 6144 patients died, of which 4508 (73.4%) were due to CVD. AKI without CKD (HR: 1.54, 95% CI: 1.36-1.74), CKD without AKI (HR: 2.02, 95% CI: 1.88-2.17), AKI with CKD (HR: 3.26, 95% CI: 2.90-3.66), and end-stage kidney disease (ESKD; HR: 5.63, 95% CI: 4.40-7.20) were significantly associated with all-cause mortality. Adjusted HR (95% CIs) for cardiovascular mortality was significantly elevated among patients with AKI without CKD (1.78 [1.54-2.06]), CKD without AKI (2.28 [2.09-2.49]), AKI with CKD (3.99 [3.47-4.59]), and ESKD (6.46 [4.93-8.46]). In conclusion, this study shows that acute or CKD is present in up to one-third of patients undergoing CAG and is associated with a substantially increased mortality. These findings highlight the importance of perioperative management of kidney function, especially in patients with CKD.Impact StatementWhat is already known on this subject? Acute kidney injury (AKI) occurred in 12.8% of patients undergoing surgery and is linked to a 22.2% increase in mortality. Chronic kidney disease (CKD) is a well-known risk for death and cardiovascular events. Effects of AKI and CKD on patients undergoing coronary angiography (CAG) remain incompletely defined.What do the results of this study add? This study shows that kidney disease is present in up to one-third of patients undergoing CAG and is associated with a substantially increased mortality. AKI and CKD are independent predicators for mortality in patients undergoing CAG.What are the implications of these findings for clinical practice and/or further research? These findings highlight the importance of perioperative management of kidney function, especially in patients with CKD.

Clinical assessment of blood pressure in 60 girls with Turner syndrome compared to 1888 healthy Danish girls.

OBJECTIVE: Hypertension contributes to increased risk of cardiovascular disease in patients with Turner syndrome (TS). Our objective was to evaluate blood pressure (BP) in girls with TS followed longitudinally through childhood and adolescence compared to a newly established BP reference material. DESIGN: Cohort study with data collected from 1991 to 2019 consisting of a population-based reference cohort and a group of girls with TS followed at a single tertiary centre. PATIENTS/PARTICIPANTS: Reference population of 1888 healthy girls with 4890 BP recordings and 60 girls with TS with 365 BP recordings. MEASUREMENTS: Difference in diastolic BP (DBP) and systolic BP (SBP), expressed in standard deviation scores (SDS), between girls with TS and the reference population, unadjusted and adjusted for BMI. Difference in BP (SDS) between TS subgroups (karyotype, oestrogen treatment, cardiac diagnosis). RESULTS: The girls with TS had significantly higher DBP (mean ± SD, 0.72 SDS ± 0.95; p < .001) and SBP (0.53 SDS ± 1.11; p = .001) than the reference population. Adjusted for BMI, girls with TS had significantly higher DBP (mean ± SE, 0.71 SDS ± 0.12; p < .001) but not SBP (0.17 SDS ± 0.16; p = .29). There was no significant difference in DBP (median, IQR: 0.97 SDS, 0.30-1.58 vs. 0.76 SDS, 0.10-1.20; p = .31) or SBP (0.51 SDS, 0.15-1.30 vs. 0.57 SDS, -0.30 to 1.05; p = .67) between individuals with or without a cardiac diagnosis. In the TS population, 55% (31/56) had at least one BP recording above the hypertension threshold. CONCLUSIONS: Our findings indicate that standardised longitudinal routine monitoring of BP in girls with TS already in childhood is of utmost importance.

Renal outcomes according to renal replacement therapy modality and treatment protocol in the ATN and RENAL trials.

BACKGROUND: In critically ill patients with acute kidney injury, renal replacement therapy (RRT) modality and treatment protocols may affect kidney recovery. This study explored whether RRT modality and treatment protocol affected RRT dependence in the 'Randomized Evaluation of Normal versus Augmented Level of RRT' and the 'Acute Renal Failure Trial Network' (ATN) trials. METHODS: Primary outcome was 28-day RRT dependence. Secondary outcomes included RRT dependence among survivors and in different SOFA-based treatment protocol groups. We used the Fine-Gray competing-risk model sub-distribution hazard ratio (SHR) to assess the primary outcome. Analyses were adjusted for confounders. RESULTS: Of 2542 patients, 2175 (85.5%) received continuous RRT (CRRT) and 367 (14.4%) received intermittent hemodialysis (IHD) as first RRT modality. CRRT-first patients had greater illness severity. After adjustment, there was no between-group difference in 28-day RRT dependence (SHR, 0.96 [95% CI 0.84-1.10]; p = 0.570) or hospital mortality (odds ratio [OR], 1.14 [95% CI 0.86-1.52]; p = 0.361) However, among survivors, CRRT-first was associated with decreased 28-day RRT dependence (OR, 0.54 [95% CI 0.37-0.80]; p = 0.002) and more RRT-free days (common OR: 1.38 [95% CI 1.11-1.71]). Moreover, among CRRT-first patient, the ATN treatment protocol was associated with fewer RRT-free days, greater mortality, and a fourfold increase in RRT dependence at day 28. CONCLUSIONS: There was no difference in RRT dependence at day 28 between IHD and CRRT. However, among survivors and after adjustment, both IHD-first and the ATN treatment protocol were strongly associated with greater risk of RRT dependence at 28 days after randomization. Trial registration NCT00221013 registered September 22, 2005, and NCT00076219 registered January 19, 2004.

Artificial intelligence for the prediction of acute kidney injury during the perioperative period: systematic review and Meta-analysis of diagnostic test accuracy.

BACKGROUND: Acute kidney injury (AKI) is independently associated with morbidity and mortality in a wide range of surgical settings. Nowadays, with the increasing use of electronic health records (EHR), advances in patient information retrieval, and cost reduction in clinical informatics, artificial intelligence is increasingly being used to improve early recognition and management for perioperative AKI. However, there is no quantitative synthesis of the performance of these methods. We conducted this systematic review and meta-analysis to estimate the sensitivity and specificity of artificial intelligence for the prediction of acute kidney injury during the perioperative period. METHODS: Pubmed, Embase, and Cochrane Library were searched to 2nd October 2021. Studies presenting diagnostic performance of artificial intelligence in the early detection of perioperative acute kidney injury were included. True positives, false positives, true negatives and false negatives were pooled to collate specificity and sensitivity with 95% CIs and results were portrayed in forest plots. The risk of bias of eligible studies was assessed using the PROBAST tool. RESULTS: Nineteen studies involving 304,076 patients were included. Quantitative random-effects meta-analysis using the Rutter and Gatsonis hierarchical summary receiver operating characteristics (HSROC) model revealed pooled sensitivity, specificity, and diagnostic odds ratio of 0.77 (95% CI: 0.73 to 0.81),0.75 (95% CI: 0.71 to 0.80), and 10.7 (95% CI 8.5 to 13.5), respectively. Threshold effect was found to be the only source of heterogeneity, and there was no evidence of publication bias. CONCLUSIONS: Our review demonstrates the promising performance of artificial intelligence for early prediction of perioperative AKI. The limitations of lacking external validation performance and being conducted only at a single center should be overcome. TRIAL REGISTRATION: This study was not registered with PROSPERO.

An investigation of glutamate quantification with PRESS and MEGA-PRESS.

Glutamate is an important neurotransmitter. Although many studies have measured glutamate concentration in vivo using magnetic resonance spectroscopy (MRS), researchers have not reached a consensus on the accuracy of glutamate quantification at the field strength of 3 T. Besides, there is not an optimal MRS protocol for glutamate measurement. In this work, both simulation and phantom scans indicate that glutamate can be estimated with reasonable accuracy (<10% error on average) using the standard Point-RESolved Spectroscopy (PRESS) technique with TE 30 ms; glutamine, however, is likely underestimated, which is also suggested by results from human scans using the same protocol. The phantom results show an underestimation of glutamate and glutamine for PRESS with long TE and MEGA-PRESS off-resonance spectra. Despite the underestimation, there is a high correlation between the measured values and the true values (r > 0.8). Our results suggest that the quantification of glutamate and glutamine is reliable but can be off by a scaling factor, depending on the imaging technique. The outputs from all three PRESS sequences (TE = 30, 68 and 80 ms) are also highly correlated with each other (r > 0.7) and moderately correlated (r > 0.5) with the results from the MEGA-PRESS difference spectra with moderate to good shimming (linewidth < 16 Hz).

Acute interstitial nephritis and nephrogenic diabetes insipidus following treatment with sulfamethoxazole-trimethoprim and temozolomide.

We report a case of acute interstitial nephritis with associated nephrogenic diabetes insipidus in a patient treated with temozolomide and sulfamethoxazole-trimethoprim for glioblastoma multiforme. Kidney biopsy demonstrated focal tubulointerstitial change with tubular dilatation, epithelial change and interstitial inflammation. The patient's kidney function improved with cessation of sulfamethoxazole-trimethoprim and treatment with hydrochlorothiazide for nephrogenic diabetes insipidus. Recommencement of temozolomide did not result in further deterioration in kidney function. In this case report, we discuss the novel association between sulfamethoxazole-trimethoprim-induced acute interstitial nephritis and nephrogenic diabetes insipidus, and suggest possible mechanisms involved.

Roxadustat in treating anemia in dialysis patients (ROAD): protocol and rationale of a multicenter prospective observational cohort study.

BACKGROUND: Roxadustat has been shown effective in treating patients with anemia due to chronic kidney disease. However, its long-term effect on clinical outcomes and socioeconomic burden and safety remains unclear. METHODS/DESIGN: This is a multicenter, prospective, longitudinal observational cohort study assessing if Roxadustat improves prognosis in dialysis patients. Primary outcomes will be major adverse cardiovascular events (MACE), defined as composites of cardiovascular death, myocardial infarction, cerebral infarction, hospitalization because of heart failure; all-cause mortality, and annual economic costs in two years. The data will be collected via Research electronic data capture (REDCap) based database as well as software-based dialysis registry of Sichuan province. The primary outcomes for the ROAD study participants will be compared with those in the dialysis registry cohort. Data at baseline and study follow up will also be compared to assess the association between Roxadustat and long-term clinical outcomes. DISCUSSION: The main objective of this study is to the assess long-term association of Roxadustat on MACE, all-cause mortality, socio-economic burden, safety in dialysis patients, which will provide guidance for designing further large randomized controlled trials to investigate this clinic question. STUDY REGISTRATION: The study has been registered in Chinese Clinical Trials Registry (ROAD, ROxadustat in treating Anemia in Dialysis patients, registration number ChiCTR1900025765) and provincial observational cohort database (Renal disEAse observational CoHort database, REACH, ChiCTR1900024926), registered 07 September 2019, http://www.chictr.org.cn .

Clinical Stratification of Pregnant COVID-19 Patients based on Severity: A Single Academic Center Experience.

OBJECTIVE: This study aimed to describe baseline characteristics of a cohort of pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and determine if these correlate with disease severity and perinatal outcomes. STUDY DESIGN: This was a retrospective cohort trial conducted at the University of Texas Medical Branch Galveston, Texas. All pregnant women presented to our medical center, who were screened and tested positive for SARS-CoV-2 virus, were included. We stratified our study population in three groups: asymptomatic, symptomatic not requiring oxygen therapy, and patients requiring oxygen support to maintain oxygen saturation >94%. Relevant population characteristics, laboratory data, and maternal and neonatal outcomes were abstracted. A p-value <0.05 was considered statistically significant. RESULTS: Between March and July 2020, 91 women tested positive for SARS-CoV-2 upon admission to our labor and delivery unit. Among these, 61.5% were asymptomatic, 34.1% were symptomatic, and 4.4% required oxygen support. Our population was mainly Hispanic (80.2%), multiparous (76.9%), obese (70.3%), and with a median age of 27 years. Median gestational age at symptom onset or diagnosis was 36 weeks. Significant differences were found between gestational age and disease severity. Maternal characteristics including age, body mass index (BMI), and presence of comorbid conditions did not appear to influence severity of SARS-CoV-2 infection. Significant laboratory findings associated with increasing disease severity included decreasing hemoglobin and white blood cell count, lymphopenia, and increasing levels of inflammatory markers including CRP, ferritin, and procalcitonin. Maternal and neonatal outcomes did not differ among groups. No SARS-CoV-2 was detected by polymerase chain reaction testing in neonates of mothers with COVID-19. CONCLUSION: Pregnant patients with COVID-19 infection are predominantly asymptomatic. Patients appear to be at increased risk for more severe infection requiring oxygen support later in pregnancy. KEY POINTS: · The majority of pregnant patients with COVID-19 are asymptomatic and <1 in 20 require oxygen support.. · Women in the later stages of pregnancy may be at increased risk for severe infection.. · Anemia, leukopenia, CRP, ferritin, and procalcitonin are associated with increasing severity..

Development of Pelvic Inflammatory Disease after Ectopic Removal.

Although ectopic pregnancy and pelvic inflammatory disease (PID) are separately commonly seen in practice, development of PID after surgical removal is rare. Here, we present the case of a 41-year-old female who was admitted for pelvic inflammatory disease diagnosed after laparoscopic salpingectomy for a ruptured ectopic pregnancy. Treatment required drainage of TOAs with interventional radiology and antibiotic treatment. This case report demonstrates how treatment of PID following ectopic pregnancy is complex and may require surgical- or radiology-guided drainage of infection in addition to common antibiotic treatment. Follow-up and duration of treatment are highlighted.

Effect of nephrology follow-up on long-term outcomes in patients with acute kidney injury: A systematic review and meta-analysis.

AIM: Acute kidney injury (AKI) is associated with poor short-term and long-term clinical outcomes. The role of nephrology follow-up in post-AKI management remains uncertain. METHODS: A systematic review and meta-analysis were performed examining all randomized controlled trials and observational studies assessing the effect of nephrology follow-up on patients' clinical outcomes. The primary outcome was all-cause mortality. The secondary outcomes were renal outcomes, which were defined as a composite of requirement of permanent dialysis and recurrent AKI. Pooled analysis was performed using a random-effect model. RESULTS: We identified six studies (8972 patients, mean follow-up of 49 months). Five were retrospective cohort studies and one was a prospective cohort study. Risk of bias was a concern with all studied. Only four studies reported primary and/or secondary outcomes and were included. Compared with patients without nephrology follow-up, patients with nephrology follow-up had significantly reduced mortality by 22% (three studies, 3240 patients, relative risk [RR] = 0.78, 95% confidence interval [CI] = 0.70-0.88, I2 = 0.0%). Nephrology follow-up did not improve composite renal outcomes with high heterogeneity due to significant differences in reported renal outcomes and follow-up period (two studies, 2537 patients, RR = 1.72, 95% CI = 0.49-6.05, I2 = 90.1%). CONCLUSION: Current evidence from observational studies is biased. It suggests long-term survival benefits with post-discharge nephrology follow-up in AKI patients. However, due to its low quality, such evidence is only hypothesis-generating. Nonetheless, it provides a rationale for future randomized controlled trials of nephrology follow-up in AKI patients. SUMMARY AT A GLANCE The present meta-analysis assessed the effect of nephrology follow-up on patients' clinical outcomes, and suggested long-term survival benefits in acute kidney injury (AKI) survivors. Although the study inherently comprises potential risks of bias due to paucity of available data, the results provide a rationale for future randomized controlled trials.

Transforming Psychiatry from the Classroom to the Clinic: Lessons from the National Neuroscience Curriculum Initiative.

OBJECTIVE: Individual residency programs often struggle to keep pace with scientific advances and new training requirements. Integrating a modern neuroscience perspective into the clinical practice of psychiatry is particularly emblematic of these challenges. The National Neuroscience Curriculum Initiative (NNCI) was established in 2013 to develop a comprehensive set of shared, open-access resources for teaching neuroscience in psychiatry. METHODS: The NNCI developed a collaborative, team-based approach with a peer-review process for generating and reviewing content. Teaching resources have included interactive sessions for the classroom paired with a comprehensive facilitator's guide. Brief accessible reviews and short videos have been developed for self-study and teaching in clinical settings. Dissemination efforts have included hands-on training for educators through national workshops. All resources are freely available on the NNCI website. Outcome measures have included the number of educational resources developed, feedback from workshop attendees, the number of US psychiatry residency programs who have adopted NNCI resources, as well as analytics from the NNCI website. RESULTS: To date, the NNCI has developed over 150 teaching sessions, reflecting the work of 129 authors from 49 institutions. The NNCI has run over 50 faculty development workshops in collaboration with numerous national and international organizations. Between March 2015 and June 2019, the website (www.NNCIonline.org) has hosted 48,640 unique users from 161 countries with 500,953 page views. More than 200 psychiatry training programs have reported implementing NNCI teaching materials. CONCLUSIONS: This multisite collaborative provides a model for integrating cutting-edge science into medical education and the practice of medicine more broadly.

Understanding and managing intimate partner violence in the pediatric primary care setting: a review.

PURPOSE OF REVIEW: To highlight the impact of intimate partner violence (IPV), also known as domestic violence, on children and families and to provide a framework for pediatricians in managing IPV-affected families. RECENT FINDINGS: Children living with a victim of IPV are at a much higher risk of being physically abused themselves. Exposure to IPV places children at high risk for multiple adverse childhood experiences, long-term health morbidity, and increased chance of intergenerational transmission of child abuse and future IPV. Exposure to a violent home environment alone is considered a form of child maltreatment. Furthermore, recent studies have proposed that maternal posttraumatic stress disorder and ineffective parenting styles by a victim of IPV mediate children's negative developmental outcomes, such as aggressive or internalizing behavior, mental health issues, and developmental delays. Trauma-informed care and a better understanding of the child abuse reporting process allow pediatricians to address specific needs of children and families exposed to IPV, to serve as mandated reporters with sensitivity and empathy, and to promote resiliency in families. SUMMARY: IPV is a public health issue that affects children in a variety of ways. Pediatricians can better manage this very serious and personal issue in their offices through an understanding of the unique healthcare needs of children and families impacted by IPV.

Effects of intravenous hydration on risk of contrast induced nephropathy and in-hospital mortality in STEMI patients undergoing primary percutaneous coronary intervention: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The role of intravenous hydration at the time of primary percutaneous intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) remains unclear. Guidelines are vague, supported by low level evidence, and hydration is used less often than other clinical settings.To perform a systematic review and meta-analysis of all randomized controlled trials assessing intravenous hydration compared with non-hydration for prevention of contrast induced nephropathy (CIN) and In-hospital mortality in patients with STEMI undergoing primary PCI. METHODS: Medline, EMBASE and the Cochrane Register were searched to September 2018. Included studies reported the incidence of CIN, In-hospital mortality, requirement for dialysis and heart failure. Relative risks with 95% confidence intervals (CIs) for individual trials were pooled using a random effects model. RESULTS: Three moderate quality trials were identified including 1074 patients. Overall, compared with no hydration, intravenous hydration significantly reduced the incidence of CIN by 42% (RR 0.58; 95% CI: 0.45 to 0.74, p < 0.001). The estimated effects upon all-cause mortality (RR 0.56; 95% CI: 0.30 to 1.02, p = 0.057) and the requirement for dialysis (RR 0.52, 95% CI 0.14-1.88, p = 0.462) were not statistically significant. The outcome of heart failure was not consistently reported. CONCLUSIONS: Intravenous hydration likely reduces the incidence of CIN in patients with STEMI undergoing primary PCI. However, for key clinical outcomes such as mortality, heart failure and dialysis the effect estimates were imprecise. Further high quality studies are needed to clarify the appropriate volume of fluid and effects on outcomes.

SOFA coagulation score and changes in platelet counts in severe acute kidney injury: Analysis from the randomized evaluation of normal versus augmented level (RENAL) study.

AIM: To evaluate the prognostic value of baseline SOFA coagulation score (SOFA-CS) and change in platelet counts in patients with severe acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT). METHODS: We performed a secondary analysis from the Randomized Evaluation of Normal versus Augmented Level of RRT (RENAL) study. The primary endpoint was all-cause mortality at 90 days after randomization. The association between baseline SOFA-CS, changes in platelet counts, process of care, and clinical outcomes were analyzed using multivariate Cox model adjusted for baseline variables. RESULTS: The complete SOFA-CS data were available in 1454 out of 1508 patients from the RENAL study. Among them, 708 patients had an abnormal SOFA-CS (defined as SOFA-CS ≥ 1), while 746 patients had normal SOFA-CS at baseline (SOFA-CS = 0). An abnormal SOFA-CS was independently associated with an increased risk of death at 90 days (HR = 1.27, 95% CI = 1.05-1.53, P = 0.015). An abnormal SOFA-CS was associated with prolonged length of ICU stay and duration of mechanical ventilation as well. Furthermore, there was no significant association between changes in platelet counts in patients who survived beyond 4 days and 90 day mortality (HR = 1.26, 95% CI = 0.29-5.56, P = 0.76). However, on multivariable analysis a decline of ≥60% (HR = 1.93, 95% CI = 1.23-3.05, P = 0.004) was associated with 90 day mortality in patients who survived beyond the first 4 days. CONCLUSIONS: In the RENAL study, thrombocytopaenia is a common phenomenon in patients with severe AKI receiving CRRT. An abnormal baseline SOFA-CS and reductions in platelet counts were associated with increased mortality at 90 days.
