Heterogeneity and Spatial Distribution of Intravertebral Trabecular Bone Mineral Density in the Lumbar Spine Is Associated With Prevalent Vertebral Fracture

The spatial heterogeneity in trabecular bone density within the vertebral centrum is associated with vertebral strength and could explain why volumetric bone mineral density (vBMD) exhibits low sensitivity in identifying fracture risk. This study evaluated whether the heterogeneity and spatial distribution of trabecular vBMD are associated with prevalent vertebral fracture. We examined the volumetric quantitative computed tomography (QCT) scans of the L3 vertebra in 148 participants in the Framingham Heart Study Multidetector CT study. Of these individuals, 37 were identified as cases of prevalent fracture, and 111 were controls, matched on sex and age with three controls per case. vBMD was calculated within 5‐mm contiguous cubic regions of the centrum. Two measures of heterogeneity were calculated: (i) interquartile range (IQR); and (ii) quartile coefficient of variation (QCV). Ratios in the spatial distributions of the trabecular vBMD were also calculated: anterior/posterior, central/outer, superior/mid‐transverse, and inferior/mid‐transverse. Heterogeneity and spatial distributions were compared between cases and controls using Wilcoxon rank sum tests and t tests and tested for association with prevalent fractures with conditional logistic regressions independent of integral vBMD. Prevalent fracture cases had lower mean ± SD integral vBMD (134 ± 38 versus165 ± 42 mg/cm3, p < .001), higher QCV (0.22 ± 0.13 versus 0.17 ± 0.09, p = .003), and lower anterior/posterior rBMD (0.65 ± 0.13 versus 0.78 ± 0.16, p < .001) than controls. QCV was positively associated with increased odds of prevalent fracture (OR 1.61; 95% CI, 1.04 to 2.49; p = .034), but this association was not independent of integral vBMD (p = .598). Increased anterior/posterior trabecular vBMD ratio was associated with decreased odds of prevalent fracture independent of integral vBMD (OR 0.38; 95% CI, 0.20 to 0.71; p = .003). In conclusion, increased trabecular vBMD in the anterior versus posterior centrum, but not trabecular vBMD heterogeneity, was associated with decreased risk of prevalent fracture independent of integral vBMD. Regional measurements of trabecular vBMD could aid in determining the risk and underlying mechanisms of vertebral fracture. © 2019 American Society for Bone and Mineral Research.
Transmission potential of paromomycin-resistant Leishmania infantum and Leishmania donovani.

OBJECTIVES Former studies demonstrated quick selection of paromomycin resistance for Leishmania infantum and Leishmania donovani accompanied by increased fitness. The present study aimed to interpret these findings in an epidemiological context by comparing infection of WT and experimentally derived paromomycin-resistant strains in the sand fly vector. METHODS Depending on the Leishmania species, Lutzomyia longipalpis and Phlebotomus perniciosus or Phlebotomus argentipes sand flies were artificially infected with procyclic promastigotes of WT and paromomycin-resistant L. infantum (MHOM/FR/96/LEM3323-cl4) or L. donovani (MHOM/NP/03/BPK275/0-cl18). The infection rate and gut/stomodeal valve colonization were determined to monitor parasite phenotypic behaviour within the vector. The impact of the previously described gain of fitness in the vertebrate host on infectivity for the vector was assessed by feeding L. longipalpis on Syrian golden hamsters heavily infected with either WT or paromomycin-resistant parasites. RESULTS WT and paromomycin-resistant Leishmania of both species behaved similarly in terms of infection and parasite location within the studied sand fly species. Blood feeding on infected hamsters did not reveal differences in acquisition of WT and paromomycin-resistant parasites, despite the higher organ burdens observed for the paromomycin-resistant strain. Strains remained resistant after passage in the vector. CONCLUSIONS Although paromomycin-resistant parasites show an increased parasite fitness in vitro and in laboratory rodents, the intrinsic infection potential of paromomycin-resistant parasites remains unaltered in the sand fly. Of importance is the fact that paromomycin-resistant Leishmania are able to complete development in the natural vectors and produce stomodeal infection with metacyclic forms, which clearly suggests their potential to spread and circulate in nature.
Impact of Community Pharmacist Interventions With Managed Care to Improve Medication Adherence

Background: Nonadherence to medications is a concern due to adverse outcomes and higher costs of care. The Centers for Medicare and Medicaid Services has made adherence a key measurement for Star ratings. Objective: To evaluate the impact of a collaborative pilot program between a third-party payer, local pharmacy organization, and academic institution focusing on improving medication adherence with community pharmacies. Methods: Twenty-five community pharmacies implemented adherence-based interventions in patients ≥65 years old, who were Medicare Advantage Plan members, taking targeted medications (statins, oral diabetic medications, angiotensin-converting enzyme inhibitors [ACE-Is] and angiotensin receptor blockers [ARBs]). Outcome measures were (1) pharmacy intervention completion rate, (2) type of adherence interventions, (3) change in the proportion of days covered (PDC) following pharmacist intervention based on adherence group, and (4) nonadherence barriers. Results: A total of 1263 interventions met the eligibility criteria, and common interventions included explaining the benefit of the medication (n = 453, 35.9%) and provider follow-up (n = 109, 8.6%). Among nonadherent subjects who became adherent, the mean PDC increased by 14% (74%-88%, P < .0001), with a 12% decrease in mean PDC score in the nonadherent who remained nonadherent group (71%-58%, P < .0001). Common patient barriers for nonadherence were forgetfulness (n = 451, 35.7%) and denial (n = 84, 6.7%). System and therapeutic barriers included complexity (n = 155, 12.3%) and adverse side effects (n = 42, 3.3%). Conclusion: This collaborative effort successfully implemented a community pharmacist-led adherence intervention in 25 independent pharmacies. Our findings highlight increased interactions with patients and in some cases improved adherence measures. Future research must include implementation outcomes in order to effectively implement these interventions in the community pharmacy setting.
Knowledge, attitude and practices of obstetric care providers towards maternal red‐blood‐cell immunization during pregnancy

A successful routine RBC alloantibody screening programme should not lead to unnecessary emotional burden during pregnancy due to inadequate counselling on the risk of severe haemolytic disease of the foetus and the newborn (HDFN). Rareness of this disease may result in insufficient knowledge and subsequent inadequate information transfer to women, diagnosed with RBC antibodies. We investigated the current knowledge, views and experiences of Dutch obstetric care providers regarding RBC alloimmunization during pregnancy.
Costs of Inpatient Rehabilitation for Ischemic Stroke in Patients with Dementia: A Cohort Swedish Register-Based Study

Background: Stroke and dementia are frequent comorbidities. Dementia possibly increases total costs of stroke care, especially cost of institutionalization and informal medical care. However, stroke rehabilitation costs in dementia patients are understudied. Objective: To estimate inpatient stroke rehabilitation costs for Swedish dementia patients in comparison with non-dementia patients. Methods: A longitudinal cohort study with linked data from the Swedish Dementia Register and the Swedish Stroke Register was conducted. Patients diagnosed with dementia who suffered a first ischemic stroke between 2010 and 2014 (n = 138) were compared with non-dementia patients (n = 935). Cost analyses were conducted from a Swedish health care perspective. The difference of rehabilitation costs between the two groups was examined via simple linear regression (before and after matching by propensity scores of dementia) and multiple linear regression. Results: Mean inpatient rehabilitation costs for dementia and non-dementia patients were SEK 103,693/$11,932 and SEK 130,057/$14,966, respectively (median SEK 92,183/$10,607 and SEK 106,365/$12,239) (p = 0.001). Dementia patients suffered from more comorbidities and experienced lower functioning, compared to non-dementia patients. The inpatient rehabilitation cost for patients with known dementia was 0.84 times the cost in non-dementia individuals. Conclusion: Dementia diagnosis was significantly associated with lower inpatient stroke rehabilitation costs. This might be explained by physicians’ beliefs on the limited effectiveness of rehabilitation in dementia patients. Further research on cost-effectiveness of stroke rehabilitation and patients’ satisfaction with stroke rehabilitation is necessary.
Association Between Automotive Assembly Plant Closures and Opioid Overdose Mortality in the United States

Key Points Question Are closures of US automobile assembly plants associated with increases in opioid overdose mortality rates among working-age adults? Findings In this difference-in-differences study, US manufacturing counties that experienced an automotive assembly plant closure were compared with counties in which automotive plants remained open from 1999 to 2016. Automotive assembly plant closures were associated with a statistically significant increase in county-level opioid overdose mortality rates among adults aged 18 to 65 years. Meaning Automotive assembly plant closures were associated with increases in opioid overdose mortality, highlighting the potential importance of the role of declining economic opportunity in the US opioid overdose crisis.
New Endovascular Approach for Hypothermia With Intrajugular Cooling and Neuroprotective Effect in Ischemic Stroke

Supplemental Digital Content is available in the text. Background and Purpose— Induction of hypothermia as a stroke therapy has been limited by logistical challenges. This study was designed to determine the hypothermic and neuroprotective efficacy of infusing cold saline directly into the internal jugular (IJ) vein and compare the effects of IJ hypothermia to those achieved by intracarotid artery hypothermia in an ischemic stroke model. Methods— The right middle cerebral artery was occluded in rats using an intraluminal filament. Immediately following reperfusion, hypothermia was achieved by infusing isotonic saline through microcatheter into the right IJ or right intracarotid over 30 minutes. Infarct sizes, neurological deficits, blood-brain barrier damage, edema volume, blood-brain barrier associated molecules (MMP-9 [matrix metallopeptidase 9] and AQP-4 [aquaporin 4]), and apoptosis-associated proteins (Bcl-2 and cleaved Caspase-3) were measured. Results— We found that both IJ- and intracarotid-based infusion cooled the brain robustly with a minimal effect on rectal temperatures. This brain cooling led to significantly reduced infarct volumes at 24 hours after reperfusion, as well as decreased expression of the proapoptotic protein cleaved Caspase-3 and increased expression of the antiapoptotic protein Bcl-2. Intracarotid and IJ cooling also aided in blood-brain barrier maintenance, as shown by decreased edema volumes, reduced Evans Blue leakage, and decreased expression of edema-facilitating proteins (MMP-9 and AQP-4). Both cooling methods then translated to preserved neurological function as determined by multiple functional tests over a 28-day observation period. Most importantly, the cooling and neuroprotective efficacy of IJ cooling was comparable to intracarotid cooling by almost every metric evaluated. Conclusions— Compared with intracarotid infusion, IJ infusion conferred a similar degree of hypothermia and neuroprotection following ischemic stroke. Given the ease of establishing vascular access via the internal jugular vein and the powerful neuroprotection that hypothermia provides, IJ brain cooling could be used as a promising hypothermia-induction modality going forward.
Transvaginal Bilateral Uterine Artery Occlusion for Treatment of Symptomatic Uterine Myomas: An Effective Modality in Low Resource Settings

Objective: To study the effectiveness and safety of bilateral uterine artery occlusion through the vaginal approach as an alternative treatment modality for symptomatic uterine myomas. Methods: Sixty-nine premenopausal women with symptomatic uterine leiomyomata were studied. None of them desired further pregnancy underwent bilateral vaginal uterine arteries occlusion. The primary outcome measures were patient satisfaction as regards menstrual blood loss compared with pre treatment loss and operative duration. Secondary outcome measures included postoperative pain, complications, secondary interventions, and failures. Results: Sixty-three women were completed follow up till 24 months after the procedure. The primary outcomes were encouraging as regards patient satisfaction for post treatment blood loss (90.7 %) and mean operative duration ( 35 ±9.5 minutes). After 6 months of follow-up, 6 patients resumed heavy periods and interventions needs secondary. Conclusion: Trans-vaginal occlusion of uterine arteries improved clinical symptoms in the majority of patients.
Human papillomavirus and survival of patients with sinonasal squamous cell carcinoma

To the authors' knowledge, the question of whether human papillomavirus (HPV) infection is associated with outcomes in patients with sinonasal squamous cell carcinoma (SNSCC) is not well studied at this time. In the current study, the authors investigated patterns of HPV testing and its association with survival in patients with SNSCC using the National Cancer Data Base.
Antipsychotic Overdosing and Polypharmacy in Schizophrenic Delinquents Explored

A logistic regression model for 289 cases of schizophrenic offenders in a Swiss forensic hospital between 1995 and 2016 revealed the following factors for above average levels of antipsychotic overdosing and polypharmacy: Odds for overdosing increased in absence of a personality disorder (237%), for each point increase in emotional withdrawal (63.5%) and motor retardation (71.7%), and decreased for poor rapport (42.3%) recorded at admission. Odds for polypharmacy increased with complaints about physicians (157%), for each point increase in IQ (3.6%; range = 65–131, M = 92, SD = 14), reduction of the security level of the ward (36.8%; four levels), and for each point increase in poor attention (27.6%) at admission. It decreased with each previous conviction (10.9%; range = 1–21, M = 3, SD = 2), breaking of rules (46.4%) and the administration of compulsory measures (55.7%) on the ward, a poor legal prognosis (29.4%, four levels), and each point increase in grandiosity (40.3%), passive social withdrawal (42.3%), and depressive symptoms (38.7%) at admission.
Glucose Time-In-Range, Time-Above-Range, and Time-Below-Range Depend on Mean or Median Glucose or HbA1c, Glucose Coefficient of Variation (%CV), and Shape of the Glucose Distribution.

BACKGROUND Examine the expected relationships between Time In Range %TIR, Time Above Range (%TAR), and Time Below Range (%TBR) with Median Glucose (or %HbA1c) and %Coefficient of Variation (%CV) of glucose for various shapes of the glucose distribution. METHODS We considered several thresholds defining hypoglycemia and hyperglycemia and examined wide ranges of Median Glucose and %Coefficient of Variation (%CV) using three models for the glucose distribution: gaussian, log-gaussian, and a modified log-gaussian distribution. RESULTS There is a linear relationship between %TIR and Median Glucose for any specified %CV when Median Glucose is well removed from the threshold for hypoglycemia. %TIR reaches a peak when Median Glucose is close to 120 mg/dL and declines both at higher and lower Median Glucose values. There is a nearly linear relationship for %TAR and Median Glucose for a wider range of glucose (80-220 mg/dL). Risk of hypoglycemia is minimal when %CV is below 20% but rises exponentially as %CV increases or as Median Glucose decreases. Similar results were obtained for a wide range of possible shapes of the glucose distribution. These simulations are consistent with results from clinical studies. CONCLUSION Both %TIR and %TAR are approximately linearly related to mean and Median Glucose (or %HbA1c). %TAR provides linearity over a wider range than %TIR. Risk of hypoglycemia (%TBR) is critically dependent on both glycemic variability (%CV) and mean or Median Glucose. These relationships support the use of %TIR, %TAR, and %TBR as metrics of quality of glycemic control for clinical, research, and regulatory purposes.
Effectiveness of a locally produced ready‐to‐use supplementary food in preventing growth faltering for children under 2 years in Cambodia: a cluster randomised controlled trial

Abstract This cluster randomised controlled trial tested the effectiveness of a locally produced, fish‐based, ready‐to‐use supplementary food (RUSF) to prevent growth faltering (decline in z‐scores). Cambodian infants (n= 485), aged 6 to 11 months, were randomised by site to receive the RUSF, Corn‐Soy Blend++ (CSB++), micronutrient powders (MNP), or no supplement (control). The intervention was for 6 months. In unadjusted analysis, the control group had statistically significantly decreased weight‐for‐age z‐scores (WAZ; ‐0.02, 95%CI = ‐0.03 ‐ ‐0.01, P= 0.001) and height‐for‐age z‐scores (HAZ; ‐0.07, 95%CI = ‐0.09 ‐ ‐0.05, P < 0.001), and increased mid‐upper arm‐circumference (MUAC; 0.02cm, 95%CI = 0.01 ‐ 0.04, P = 0.010), but no statistically significant change in weight‐for‐height z‐scores (WHZ). The RUSF group did not differ significantly from the control for WAZ, HAZ or WHZ (in other words, WAZ and HAZ decreased and WHZ did not change), but had increased MUAC in comparison to the control (0.04cm, 95%CI = 0.01 ‐ 0.06, P = 0.008). There were no statistically significant differences between the RUSF group and the CSB++ or MNP groups with respect to WAZ, HAZ, WHZ or MUAC. Interestingly, in adjusted analysis, low consumers of RUSF had increased WAZ, WHZ and MUAC (0.03, 95%CI = 0.01‐0.06, P = 0.006; 0.04, 95%CI = 0.01‐0.08, P = 0.026; and 0.05cm, 95%CI = 0.02‐0.09, P = 0.004, respectively) compared with the control. The novel RUSF, particularly in small quantities, protected against ponderal growth faltering, but the improvements were of limited clinical significance.
Improving sensory representations using episodic memory

The medial temporal lobe (MTL) is well known to be essential for declarative memory. However, a growing body of research suggests that MTL structures might be involved in perceptual processes as well. Our previous modeling work suggests that sensory representations in cortex influence the accuracy of episodic memory retrieved from the MTL. We adopt that model here to show that, conversely, episodic memory can also influence the quality of sensory representations. We model the effect of episodic memory as (a) repeatedly replaying episodes from memory and (b) recombining episode fragments to form novel sequences that are more informative for learning sensory representations than the original episodes. We demonstrate that the performance in visual discrimination tasks is superior when episodic memory is present and that this difference is due to episodic memory driving the learning of a more optimized sensory representation. We conclude that the MTL can, even if it has only a purely mnemonic function, influence perceptual discrimination indirectly.
The Prevalence of Dementia: A Systematic Review and Meta-Analysis.

Dementia is a severe neurodegenerative disorder and it can be categorized into several subtypes by different pathogenic causes. We sought to comprehensively analyzed the prevalence of dementia from perspectives of geographic region (Asia, Africa, South America, and Europe/North America), age, and gender. We searched PubMed and EMBASE for relevant articles on dementia published from January 1985 to August 2019. In these studies, analyses were stratified by geographic region, age, and gender. Meta-regression was conducted to identify if there were significant differences between groups. We included forty-seven studies. Among the individuals aged 50 and over in the community, the pooled prevalence for all-cause dementia, Alzheimer's disease, and vascular dementia were 697 (CI95% : 546-864) per 10,000 persons, 324 (CI95% : 228-460) per 10,000 persons, and 116 (CI95% : 86-157) per 10,000 persons, respectively. In our study, the prevalence of all-type dementia in individuals aged 100 years and older (6,592 per 10,000 cases) is 2.415 times higher than in those aged 50-59 (27 per 10,000 cases). The number of people living with dementia approximately doubles every five years. The prevalence was greater in women than in men (788 cases versus 561 cases per 10,000 persons) in overall analysis. In individuals aged 60 to 69 years, AD prevalence in females was 1.9 times greater than that in males (108 cases versus 56 cases per 10,000 persons), while the prevalence of VaD was 1.8 times greater in males than in females (56 cases versus 32 cases per 10,000 persons). Prevalence rate was higher in Europe and North America than in Asia, Africa, and South America.
Antiepileptic Drugs and Suicidality in Veterans with Seizures.

Objectives Veterans and patients with epilepsy are at higher risk of suicide than the general population. Some studies suggest that antiepileptic drugs (AEDs) further increase the risk of suicide. The nature of the relationship between suicidality and epilepsy treatment needs clarification. We examined this relationship in a cohort of veterans with seizures. Methods We performed a retrospective chart analysis of patients at the Philadelphia VA Medical Center with a diagnosis of seizure disorder between January 2000 and April 2007. Patients with suicidal ideation and/or suicidal behaviors were analyzed with respect to the following risk factors: age, history of traumatic brain injury (TBI), substance abuse and AED prescription. Results 526 charts were reviewed, 385 of which met inclusion criteria. Patients with substance abuse were more likely to have suicidal ideation (adjusted odds ratio 3.37, 95% CI 1.84 -6.18). Risk decreased with age (adjusted odds ratio 0.94, 95% CI 0.92 - 0.97 for each year). There was no statistically significant relationship between suicidality and AED use or history of TBI. Conclusion In our population, AEDs were not associated with increased risk of suicidality, whereas substance abuse was associated with a substantial risk increase. The interactions among seizures, suicidality, substance abuse and other neuropsychiatric diseases are complex. Large-scale studies in patients with seizures are needed to understand the impact of individual drugs and other contributing factors. Providers should be cautious not to withhold potentially beneficial treatment, however patients with risk factors such as history of substance abuse should be followed closely after AED initiation or adjustment.
