Background: The maternal continuum of care (CoC) (antenatal care, facility-based delivery, postnatal care) is critical to maternal and neonatal health and reducing mortality, but completion in rural areas of low- and middle-income countries is often limited. We used repeated cross-sectional household surveys from a rural Liberian county to explore changes in rates of completion of all steps and no steps in the maternal CoC after implementation of the National Community Health Assistant Program (NCHAP), a community health worker (CHW) intervention designed to increase care uptake for families over five kilometers from a facility., Methods: We analyzed repeated cross-sectional household surveys of women aged 18-49 served by NCHAP in Rivercess County, Liberia. We measured survey-weighted, before-to-after implementation difference in completion of all steps and no steps in the maternal CoC. We used multivariable regression to explore covariates associated with completion rates before and after NCHAP implementation., Results: Data from surveys conducted at three timepoints (2015, n = 354; 2018, n = 312; 2021, n = 302) were analyzed. A significant increase in completing the full maternal CoC (2015:23.6%, 2018:53.4%, change:29.7% points (pp), 95% confidence interval (CI) [21.0,38.4]) and a decrease in completing no steps in the CoC (2015:17.6%, 2018:4.0%, change: -12.4pp [-17.6, -7.2]) after implementation of NCHAP were observed from 2015 to 2018, with rates maintained from 2018 to 2021. Living farther from a facility was consistently associated with less care across the continuum. Following implementation, living in a motorbike accessible community was associated with completing the CoC while living in a mining community was negatively associated with omitting the CoC. Household wealth was associated with differences in rates pre-NCHAP but not post-NCHAP., Conclusions: Following NCHAP implementation, completion rate of the full maternal CoC in Rivercess County more than doubled while the rate of completing no steps in the continuum fell below 5%. These rates were sustained over time including during COVID-19 with reduced differences across wealth groups, although far distances remained a risk for less care. CHW programs providing active outreach to remote communities can be important tools for improving uptake of interventions and reducing risk of no formal care during and after pregnancy., (© 2023.

Background: Recommendations for promoting mental health during the COVID-19 pandemic include maintaining social contact, through virtual rather than physical contact, moderating substance/alcohol use, and limiting news and media exposure. We seek to understand if these pandemic-related behaviors impact subsequent mental health., Methods: Daily online survey data were collected on adults during May/June 2020. Measures were of daily physical and virtual (online) contact with others; substance and media use; and indices of psychological striving, struggling and COVID-related worry. Using random-intercept cross-lagged panel analysis, dynamic within-person cross-lagged effects were separated from more static individual differences., Results: In total, 1148 participants completed daily surveys [657 (57.2%) females, 484 (42.1%) males; mean age 40.6 (s.d. 12.4) years]. Daily increases in news consumed increased COVID-related worrying the next day [cross-lagged estimate = 0.034 (95% CI 0.018-0.049), FDR-adjusted p = 0.00005] and vice versa [0.03 (0.012-0.048), FDR-adjusted p = 0.0017]. Increased media consumption also exacerbated subsequent psychological struggling [0.064 (0.03-0.098), FDR-adjusted p = 0.0005]. There were no significant cross-lagged effects of daily changes in social distancing or virtual contact on later mental health., Conclusions: We delineate a cycle wherein a daily increase in media consumption results in a subsequent increase in COVID-related worries, which in turn increases daily media consumption. Moreover, the adverse impact of news extended to broader measures of psychological struggling. A similar dynamic did not unfold between the daily amount of physical or virtual contact and subsequent mental health. Findings are consistent with current recommendations to moderate news and media consumption in order to promote mental health.

Selective attention filters irrelevant information entering our brain to allow for fine-tuning of the relevant information processing. In the visual domain, shifts of attention are most often followed by a saccadic eye movement to objects and places of high relevance. Recent studies have shown that the stimulus color can affect saccade target selection and saccade trajectories. While those saccade modulations are based on perceptual color space, the level in the visual processing hierarchy at which color selection biases saccade programming remains unclear. As color has also been shown to influence manual response inhibition which is a key function of the prefrontal cortex, we hypothesized that the effects of color on executive functions would also inherently affect saccade programming. To test this hypothesis, we measured behavioral performance and saccade metrics during a modified saccadic Stroop task which reflects competition between color words ("RED" and "GREEN") and their color at the level of the prefrontal cortex. Our results revealed that the oculomotor system can differentially process red and green colors when planning a saccade in the presence of a competing distractor., (© 2022.

Objective: To evaluate for relative palpebral and orbital changes after long-term unilateral exposure to prostaglandin analogues (PGAs) in patients with childhood glaucoma., Design: Prospective cross-sectional cohort study., Participants: A total of 29 patients with history of childhood glaucoma, who were treated unilaterally with PGAs for at least 12 months., Methods: Based on 4 standardized clinical photographs (en face with eyes open, right and left side views with eyes open, and en face with eyes closed), 3 masked expert graders each independently selected the eye they perceived to have received unilateral PGA treatment by physical appearance alone and graded the following features relative to the other eye: (1) ocular (e.g., conjunctival hyperemia, iris heterochromia, and buphthalmos), (2) palpebral (e.g., eyelash trichomegaly, eyelash hypertrichosis, eyelid erythema, eyelid edema, eyelid hyperpigmentation, high upper eyelid crease, upper eyelid ptosis, upper and/or lower eyelid retraction, and eyelid skin atrophy with presence of telangiectasias), and (3) periorbital (e.g., superior sulcus hollowing, proptosis, enophthalmos, hypoglobus, and hyperglobus). An interrater reliability analysis was performed using the Fleiss kappa (κ) statistic to determine consistency among raters., Main Outcome Measures: Frequencies of each feature of prostaglandin-associated periorbitopathy (PAP); group consensus; interrater reliability of selected PGA-treatment laterality., Results: Median unilateral PGA exposure time was 31.7 months (interquartile range: 18.8-44.3 months). Eyelash trichomegaly and hypertrichosis (n = 22, 76%), high upper eyelid crease (n = 20, 69%), upper eyelid ptosis (n = 14, 52%), and superior sulcus hollowing (n = 15, 52%) were the most frequently observed features of PAP in PGA-treated eyes compared with untreated fellow eyes. Most of these changes were mild, but 20% to 30% of patients exhibited moderate eyelash and/or eyelid changes. One patient had severe PAP after long-term unilateral PGA exposure. Group consensus with correctly selected laterality was achieved in all patients. The inter-rater reliability was excellent (κ = 0.815, P < 0.001, 95% confidence interval [0.605, 1.000])., Conclusions: Mild-to-moderate changes in the ocular adnexa can develop in children and young adults with long-term PGA exposure. Patients and their families should be educated on the possibility of PAP, especially when initiating monocular PGA therapy., (Copyright © 2020 American Academy of Ophthalmology.

Purpose: Results of a small case series indicate an increased risk of dens fractures in patients with osteoarthritis. The purpose of this retrospective cohort study was to analyze the relative risks associated with degeneration of the cervical spine in the occurrence of dens fractures in older patients., Methods: We performed a retrospective CT study of 1,794 patients > 55 years of age with and without dens fractures for signs of osteoarthritis (OA)., Results: OA of the atlanto-dens interval (AdI) was present in 75.9% of fracture patients, whereas 63.5% of non-fracture patients had OA of the AdI (p = 0.04). In cases of osteoarthritis of the facet joints, we did find a significant increase (p < 0.05) in the dens fracture risk in patients with OA., Conclusions: This study indicates an association between OA of the cervical spine and the risk of sustaining a dens fracture. OA can lead to a reduction in the range of motion of the cervical spine. As a consequence, a relatively low-energy trauma can induce a forced sagittal motion, which will produce a torque at the base of the odontoid process resulting in a fracture., Competing Interests: The authors declare that they have no conflict of interest., (Georg Thieme Verlag KG Stuttgart · New York.)

Background: Heart failure (HF) is highly prevalent in the Veterans Affairs (VA) health care system and the leading cause of hospital discharges in the VA. Despite guideline-specific recommendations of drug therapy, many patients are not on optimal medication regimens. Objective: To examine and quantify pharmacist impact in an interdisciplinary HF consult (IC) service on increasing use of guideline-directed medical therapy (GDMT). The 30-day readmission rates before and after the implementation of an IC service are reported. Methods: This was a single-center retrospective analysis of veterans admitted with a HF diagnosis between August 2008 and August 2015 in 2 distinctive cohorts: pre-IC (August 2008 to November 2011) and IC (November 2011 to August 2015). Results: Four-hundred patients were included, with 200 in each cohort. All-cause readmissions at 30 days were not different between pre-IC and IC groups: 33.5% versus 28.5%, respectively. Secondary outcomes of HF readmission and 1-year mortality were not different between groups. Significant increases in medication use rates were observed from admission to discharge in both cohorts; however, greater increases were observed in the IC group in which the pharmacist role was clearly defined in recommending GDMT optimization, especially in patients with HF with reduced ejection fraction. Conclusion and Relevance: Although the implementation of an IC service did not significantly change 30-day readmission rates, increases in GDMT use are evident with increased pharmacist involvement. Longer-term outcomes associated with this intervention warrant future investigation.

Actions are informed by the complex interactions of response execution and inhibition networks. These networks integrate sensory information with internal states and behavioral goals to produce an appropriate action or to update an ongoing action. Recent investigations have shown that, behaviorally, attention is captured through a hierarchy of colors. These studies showed how the color hierarchy affected visual processing. To determine whether the color hierarchy can be extended to higher level executive functions such as response execution and inhibition, we conducted several experiments using the stop-signal task (SST). In the first experiment, we modified the classic paradigm so that the go signals could vary in task-irrelevant color, with an auditory stop signal. We found that the task-irrelevant color of the go signals did not differentially affect response times. In the second experiment we determined that making the color of the go signal relevant for response selection still did not affect reaction times(RTs) and, thus, execution. In the third experiment, we modified the paradigm so that the stop signal was a task relevant change in color of the go signal. The mean RT to the red stop signal was approximately 25 ms faster than to the green stop signal. In other words, red stop signals facilitated response inhibition more than green stop signals, however, there was no comparative facilitation of response execution. These findings suggest that response inhibition, but not execution, networks are sensitive to differences in color salience. They also suggest that the color hierarchy is based on attentional networks and not simply on early sensory processing.

Purpose: To explore sleep position in asymmetric primary open-angle glaucoma (POAG) with a focus on low pressure glaucoma (LPG)., Methods: Sleep laboratory videos of 54 POAG patients were examined for lateral sleep. Then, 29 LPG patients (intraocular pressure [IOP] < 22 mm Hg) with an intereye visual field index (VFI) asymmetry of more than 5% continuously recorded their sleep position at home for 2 nights by using a portable device. Correlations were sought between sleep position, visual field (VF), and retinal nerve fiber layer (RNFL) symmetry as well as ocular biometric data and positional IOP changes. Finally, an expanded data set of 178 POAG patients (63 LPG and 115 high pressure glaucoma [HPG; IOP ≥ 22 mm Hg]) was used to correlate VF and the RNFL symmetry to the self-assessed sleep position collected in a survey., Results: In the video analysis, patients spent 19% ± 2% (mean ± SEM) more time sleeping on one side than on the other. Right-sided sleep was preferred. Right-sided sleep was 1.6 times more common in continuously recorded home data and correlated to an asymmetric VF that was worse in the left eye (b = -0.422, P = 0.002). Pulse amplitude of left eyes was lower in the right decubitus position (P = 0.02). In the expanded survey, 73% of LPG and 58% of HPG patients slept asymmetrically. Right-sided sleepers had a worse RNFL symmetry score., Conclusions: Asymmetric sleep behavior is common. Right-sided sleep was preferred and correlated with a lower VFI on the left.

Background and Aims: Icodextrin is a starch-derived glucose polymer that causes sustained ultrafiltration in long dwells in peritoneal dialysis. The aim of this study was to assess factors that were predictive of an increment in ultrafiltration following the introduction of icodextrin in patients with refractory fluid overload., Methods: Thirty-nine patients (20 male/19 female, mean age 57.7 +/- 2.4 years) on peritoneal dialysis were enrolled in a prospective pretest/post-test, open-label study. All patients had symptomatic fluid overload refractory to fluid restriction (<800 mL/day), frusemide doses of 250 mg or more daily, optimization of dwell time and use of hypertonic dextrose. An icodextrin exchange was substituted for a 4.25% dextrose exchange for the long-dwell period., Results: After 1 month, median (interquartile range) 24 h ultrafiltration volume increased by 500 mL (interquartile range: 50-1000). An increase in ultrafiltration volume correlated positively with the dialyate : plasma creatinine ratio at 4 h (r = 0.498, P = 0.001) and negatively with the ratio of dialysate glucose concentrations at 4 and 0 h (r = -0.464, P = 0.003). On multivariate regression analysis, high transporter status was predictive of a greater ultrafiltration response to icodextrin relative to dextrose peritoneal dialysis exchanges. Age, sex, race, peritoneal dialysis duration, peritoneal dialysis modality, diabetes mellitus, baseline albumin, and baseline ultrafiltration volume were not significantly correlated with the change in ultrafiltration volume., Conclusion: Icodextrin significantly augments ultrafiltration volumes in patients with refractory fluid overload. A high peritoneal membrane transporter status is the best predictor of a favourable ultrafiltration response to icodextrin.

Background: Peritoneal transport of small solutes generally increases during the first month of peritoneal dialysis (PD). The aim of this study was to prospectively evaluate the ability of the peritoneal equilibration test (PET), carried out 1 and 4 weeks after the commencement of PD, to predict subsequent technique survival., Methods: Fifty consecutive patients commencing PD at the Princess Alexandra Hospital between 1 February 2001 and 31 May 2003 participated in the study. Paired 1 week and 1 month PET data were collated and correlated with subsequent technique survival., Results: A significant increase was observed in the dialysate : plasma creatinine ratio at 4 h (D/P Cr) between 1 and 4 weeks after the onset of PD (0.55 +/- 0.12 vs 0.66 +/- 0.11, P <0.001). Mean death-censored technique survival was superior in patients who experienced > or =20% rise in D/P Cr during the first month of PD compared with those who did not (2.3 +/- 0.2 vs 1.6 +/- 0.2 years, P <0.05). Using a multivariate Cox proportional hazards model analysis, the significant independent predictors of death-censored technique survival were an increase in D/P Cr of greater than 20% during the first month (adjusted hazard ratio [HR] 0.20, 95% CI 0.05-0.75), the absence of diabetes mellitus, the absence of ischaemic heart disease, body mass index and baseline peritoneal creatinine clearance., Conclusions: A 20% or greater rise in D/P Cr during the first month of commencing PD is independently predictive of PD technique survival. Further investigations of the mechanisms underlying this phenomenon are warranted.

Objective: The aim of this study was to prospectively evaluate the ability of a peritoneal equilibration test (PET) performed in the first week of peritoneal dialysis (PD) to predict subsequent transport status, as determined by a PET at 4 weeks and >1 year after PD commencement., Design: Prospective observational study of an incident PD cohort at a single center., Setting: Tertiary-care institutional dialysis center., Participants: The study included 50 consecutive patients commencing PD at the Princess Alexandra Hospital between 25/2/2001 and 14/5/2003 (mean age 60.9 +/- 12.2 years, 54% male, 92% Caucasian, 38% diabetic). All patients were initially prescribed continuous ambulatory PD., Main Measurements: Measurements performed during paired PETs included dialysate-to-plasma ratios of urea (D/P urea) and creatinine (D/P creatinine) at 4 hours, the ratio of dialysate glucose concentrations at 0 and 4 hours (D/D0 glucose), and drain volumes at 4 hours., Results: When paired 1-week and 1-month PET data were analyzed, significant changes were observed in measured D/P urea (0.91 +/- 0.07 vs 0.94 +/- 0.07 respectively; p < 0.05), D/P creatinine (0.55 +/- 0.12 vs 0.66 +/- 0.11, p < 0.001), and D/D0 glucose (0.38 +/- 0.08 vs 0.36 +/- 0.10, p < 0.05). Using Bland-Altman analysis, the repeatability coefficients were 0.17, 0.20, and 0.13, respectively. Agreement between 1-week and 1-month PET measurements with respect to peritoneal transport category was moderate for D/D0 glucose (weighted kappa 0.52), but poor for D/P urea (0.30), D/P creatinine (0.35), and drain volumes (0.20). The PET measurements performed more than 1 year following PD commencement (n = 28) generally agreed closely with 1-month measurements, and poorly with 1-week measurements., Conclusions: Peritoneal transport characteristics change significantly within the first month of PD. PETs carried out during this time should be considered preliminary and should be confirmed by a PET 4 weeks later. Nevertheless, performing an early D/D0 glucose measurement at 1 week predicted ultimate transport status sufficiently well to facilitate early clinical decision-making about optimal PD modality while patients were still receiving PD training. On the other hand, the widespread practice of using measured drain volumes in the first week to predict ultimate transport category is highly inaccurate and not recommended.

Previous retrospective studies have reported that icodextrin may prolong peritoneal dialysis (PD) treatment time in patients with refractory fluid overload (RFO). Because the annual cost of PD therapy is lower than that of hemodialysis (HD) therapy in Australia, we prospectively investigated the ability of icodextrin to prolong PD technique survival in patients with RFO. We used a computer model to estimate the savings associated with that therapeutic strategy, based on annual therapy costs determined in a regional PD and HD costing exercise. Patients who met standard criteria for RFO and who were otherwise to be converted immediately to HD, were asked to consent to an open-label assessment of the ability of icodextrin to delay the need to start HD. Time to conversion to HD was measured. The study enrolled 39 patients who were followed for a mean period of 1.1 years. Icodextrin significantly increased peritoneal ultrafiltration by a median value of 368 mL daily. It prolonged technique survival by a mean period of 1.21 years [95% confidence interval (CI): 0.80-1.62 years]. Extension of PD treatment time by icodextrin was particularly marked for patients who had ultrafiltration failure (UFF, n = 20), defined as net daily peritoneal ultrafiltration < 1 L daily (mean extension time: 1.70 years; 95% CI: 1.16-2.25 years). Overall, annualized savings were US$3,683 per patient per year. If just the patients with UFF were considered, the savings increased to US$4,893 per year. Icodextrin prolongs PD technique survival in patients with RFO, permitting them to continue on their preferred therapy. In Australia, that practice is highly cost-effective, particularly in individuals with UFF.

The role of strontium chloride Sr 89 in the palliative treatment of pain associated with metastatic bone disease is reviewed. Conventional therapies to relieve metastatic bone pain include nonopioid and opioid analgesics, hormonal therapy, external-beam irradiation, and chemotherapy. Limitations in the long-term safety and effectiveness of these treatments have increased interest in using systemic radioactive isotopes for palliation of pain. Strontium chloride Sr 89 is a relatively new bone-seeking radiopharmaceutical that has FDA-approved labeling for use in relieving pain associated with skeletal metastases. An analogue of calcium, strontium chloride Sr 89 is rapidly cleared from the blood after i.v. injection. The agent selectively irradiates metastatic sites while generally sparing normal soft-bone tissue. In clinical studies, a majority of patients with prostate or breast cancer obtained substantial relief from bone pain after receiving strontium chloride Sr 89 alone or in combination with external-beam irradiation. Adverse effects tend to be mild, but patients should be monitored for possible hematologic toxicity. Patients should discontinue any calcium-containing products before receiving the agent. The typical dose is 4 mCi (148 MBq) administered by slow i.v. push over one to two minutes; doses can be repeated at three-month intervals. Pain relief usually begins in 10-20 days and lasts up to six months. Radiation safety measures are necessary in handling strontium chloride Sr 89 and the wastes of patients. Strontium chloride Sr 89 is costly, but preliminary analysis indicates that it may reduce management expenditures overall.(ABSTRACT TRUNCATED AT 250 WORDS)
