RESUMEN
OBJECTIVE: Dietary interventions are the mainstay of chronic diseases prevention in general population, but the evidence to support such therapeutic approaches in patients with chronic kidney disease (CKD) is less robust. The objective of this study is to examine the association between dietary fiber intake and adverse cardiovascular and kidney outcomes and all-cause mortality in participants with CKD enrolled in the Chronic Renal Insufficiency Cohort study. DESIGN AND METHODS: A total of 3791 Chronic Renal Insufficiency Cohort participants with self-reported dietary fiber intake were included in the analyses stratified by tertiles of dietary fiber at study baseline. Hazard ratios for occurrence of all-cause mortality, composite cardiovascular events and composite kidney events were calculated using Cox Proportional Hazards models adjusted for demographic, clinical, and laboratory characteristics, including levels of inflammatory markers, C-reactive protein and interleukin-6. RESULTS: Mean daily dietary fiber intake was 15.2 g/day. During a median (standard deviation) follow up of 14.6 (4.4) years, 1074 deaths from any cause occurred. In multivariable adjusted models, participants in the middle and low dietary fiber tertiles had a 19% (hazard ratio [95% CI]), 1.19 [1.02, 1.39]) and 11% (1.11 [0.95, 1.31]) greater risk of death respectively, compared to those in the highest fiber intake tertile. No statistically significant associations were observed between dietary fiber intake and adverse cardiovascular and kidney outcomes. Higher dietary fiber intake was not significantly associated with lower levels of C-reactive protein and interleukin-6. CONCLUSION: A lower intake of dietary fiber was not associated with all-cause mortality in participants with CKD after adjustments for kidney function and inflammatory biomarkers. There was no significant association between dietary fiber intake and adverse kidney and cardiovascular outcomes. Future randomized intervention trials are needed to identify whether a high dietary fiber intake translates into improved clinical outcomes in CKD.
RESUMEN
BACKGROUND: Celiac Disease (CD) is associated with increased susceptibility to certain bacterial and viral infections. Herpes zoster (HZ) is a viral infection that can be prevented by immunization. In the US, the vaccine is recommended for adults ≥ 50 or ≥ 19 with certain at-risk conditions, not including CD. AIMS: We aimed to determine if adult patients aged < 50 or ≥ 50 years with CD had a higher risk of developing HZ. METHODS: We designed a retrospective cohort study. CD was defined as patients with the ICD-10 code for CD and positive Celiac serology. Patients with negative serology and lacking CD ICD-10 codes served as controls. Patients who had HZ before CD diagnosis were excluded. We formed two sub-cohorts, those aged < 50 (cohort 1) and aged ≥ 50 years (cohort 2), and evaluated HZ infection at 10-year follow-up. To account for confounding variables, we performed 1:1 propensity score matching (PSM). RESULTS: Following PSM, cohort 1 had 6,826 CD patients, and cohort 2 had 5,337 CD patients and respective matched controls. After ten years of follow-up, in cohort 1, 62 CD patients developed HZ versus 57 controls, RR: 1.09 (CI: 0.76-1.56, p-value = 0.64). In cohort 2, 200 CD patients developed HZ versus 159 controls, RR: 1.2 (CI: 1.02-1.54, p-value = 0.03). CONCLUSION: There was no significant difference in the likelihood of getting HZ in CD patients < 50, although CD patients ≥ 50 had a modestly increased risk. Our findings do not support routine early vaccination for HZ in CD, and the vaccine should be offered at age 50.

Rationale & Objective: The clinical significance of isolated diastolic hypertension in patients with chronic kidney disease (CKD) is unclear. We assessed the prevalence of isolated diastolic hypertension and its association with adverse kidney and cardiovascular outcomes in participants in the Chronic Renal Insufficiency Cohort (CRIC) study. Study Design: Prospective cohort study. Setting & Population: CRIC study participants with complete baseline data on systolic blood pressure (SBP) and diastolic BP (DBP) (N=5,621). Exposure: Isolated diastolic hypertension defined as SBP ≤ 130 mm Hg and DBP >80 mm Hg. Reference Group: Normotension, defined as SBP ≤ 130 mm Hg and DBP ≤ 80 mm Hg. Outcomes: Composite kidney events (50% decline in estimated glomerular filtration rate or onset of kidney failure), composite cardiovascular events (myocardial infarction, heart failure, stroke, or peripheral arterial disease), and all-cause mortality. Analytical Approach: Cox proportional hazards models adjusted for demographic, health behavior, and clinical covariates. Results: Of the 5,621 participants, 347 (6.2%) had isolated diastolic hypertension. Among the 347 participants with isolated diastolic hypertension, there was no association between isolated diastolic hypertension and the composite kidney outcome (HR, 1.17; 95% CI, 0.93-1.47; P = 0.18), composite cardiovascular events (HR, 0.91; 95% CI, 0.65-1.27; P = 0.58), or all-cause mortality (HR, 0.82; 95% CI, 0.57-1.19; P = 0.30). Limitations: Older age of cohort and low number of participants of Asian ethnicity limit generalizability of findings. A relatively small sample size is inadequate to detect modest associations with outcomes. Conclusions: Isolated diastolic hypertension was not associated with the risk of adverse kidney and cardiovascular events in participants with CKD. Plain Language Summary: Clinicians frequently encounter patients with kidney disease who have controlled systolic blood pressure (BP) but high diastolic BP and do not know whether they should intensify BP treatment in an attempt to control the diastolic BP. We examined whether having controlled systolic BP but uncontrolled diastolic BP leads to worse heart and kidney outcomes in patients with chronic kidney disease. We did not find any such association. However, our study was relatively small and had a number of limitations. Till larger studies confirm or refute this finding, we recommend not increasing blood pressure medications to improve the diastolic BP control if the systolic BP is already well controlled in patients with chronic kidney disease.
RESUMEN
Population-scale biobanks linked to electronic health record data provide vast opportunities to extend our knowledge of human genetics and discover new phenotype-genotype associations. Given their dense phenotype data, biobanks can also facilitate replication studies on a phenome-wide scale. Here, we introduce the phenotype-genotype reference map (PGRM), a set of 5,879 genetic associations from 523 GWAS publications that can be used for high-throughput replication experiments. PGRM phenotypes are standardized as phecodes, ensuring interoperability between biobanks. We applied the PGRM to five ancestry-specific cohorts from four independent biobanks and found evidence of robust replications across a wide array of phenotypes. We show how the PGRM can be used to detect data corruption and to empirically assess parameters for phenome-wide studies. Finally, we use the PGRM to explore factors associated with replicability of GWAS results.

INTRODUCTION: Peripheral artery disease (PAD) disproportionately burdens Black Americans, particularly Black men. Despite the significant prevalence and high rate of associated morbidity and mortality, awareness of and treatment initiation for PAD remains low in this demographic group. Given the well-established social cohesion among barbershops frequently attended by Black men, barbershops may be ideal settings for health screening and education to improve awareness, early detection, and treatment initiation of PAD among Black men. METHODS: A qualitative study involving 1:1 participant interviews in Cleveland, Ohio assessed perspectives of Black men about barbershop-based screening and education about PAD. Inductive thematic analysis was performed to derive themes directly from the data to reflect perceived PAD awareness and acceptability of screening in a barbershop setting. RESULTS: Twenty-eight African American/Black, non-Hispanic men completed a qualitative interview for this analysis. Mean age was 59.3 ± 11.2 years and 93% of participants resided in socioeconomically disadvantaged zip codes. Several themes emerged indicating increased awareness of PAD and acceptability of barbershop-based screenings for PAD, advocacy for systemic changes to improve the health of the community, and a desire among participants to increase knowledge about cardiovascular disease. CONCLUSIONS: Participants were overwhelmingly accepting of PAD screenings and reported increased awareness of PAD and propensity to seek healthcare due to engagement in the study. Participants provided insight into barriers and facilitators of health and healthcare-seeking behavior, as well as into the community and the barbershop as an institution. Additional research is needed to explore the perspectives of additional stakeholders and to translate community-based screenings into treatment initiation.

Breastfeeding is the optimal nutrition for infants given the numerous health benefits that are conferred on mothers, infants, and society in a dose-dependent manner. However, low breastfeeding rates and racial breastfeeding inequities persist for the African American (AA) community due to historic structural racism. The issue is especially salient at the Rainbow Center for Women and Children, an urban health center in Cleveland, Ohio where approximately 90% of their mothers are AA, WIC-eligible, and publicly insured. Our study aims to elucidate factors contributing to breastfeeding practices and identify supports that could be added for women served at RCWC. The study was conducted within 2 cohorts both of exclusively AA women. Wave 1 of the study included AA mothers who exclusively breastfed, did mixed feeding, or exclusively formula fed. Wave 2 included expectant women at least considering breastfeeding. Breastfeeding attitudes of those who had exclusively breastfed or practiced mixed feeding were not significantly different than those of expectant participants planning to breastfeed; mean attitude scores, however, were in the "neutral" range. Participants endorsed many sources of support for their feeding choices, including the infant's father, their own parents, and family. However, the data show that even when women feel personally supported in their feeding choices by their partner and family, if additional breastfeeding help is needed, they will benefit from help accessing available resources. Thus, lactation support that helps women achieve their own breastfeeding goals is optimal; customized care ultimately can move the needle on racial inequities in breastfeeding for our society.

Intrathecal trialing is used as a screening prognostic measure prior to intrathecal drug delivery system implant. The purpose of this study was to determine the efficacy of a continuous intrathecal infusion of an admixture of bupivacaine and fentanyl in patients with chronic low back pain. Patients with refractory chronic low back pain in the setting of previous lumbar spine surgery and/or chronic vertebral compression fracture(s) were enrolled in a randomized double blind cross-over study comparing saline infusion to infusion of a solution containing bupivacaine combined with low-dose fentanyl over a 14-18 hour period. The primary outcome measure was the change in pain intensity at the end of the screening trial. Patients who experienced significant pain reduction from either infusion relative to baseline pain were offered a permanent implant. In total, 36 patients were enrolled, with 31 patients trialed and 25 implanted. At the end of the screening trial, pain scores, at rest or with activity, decreased appreciably in both groups; however, significantly better improvements occurred in the fentanyl/bupivacaine group compared to saline both with activity and at rest (P = .016 and .006, respectively). Treatment order appeared to affect outcome with saline demonstrating a placebo response. At 12 months following implant, primary and secondary outcome measures continued to be significantly reduced from baseline. Continuous intrathecal delivery of a combination of zlow-dose fentanyl with bupivacaine is superior to saline in screening intrathecal trialing for back pain reduction. With longer term delivery, a sustained reduction of chronic low back pain was also observed.

OBJECTIVE: Recent studies have emphasized the early use of infliximab (IFX) in pediatric patients with inflammatory bowel disease. Standard dosing of 5 mg/kg/dose may not be sufficient to achieve optimal clinical outcomes. The aim of our study was to compare short-term outcomes with standard dosing of IFX to higher, nonstandard dosing of IFX for induction therapy. METHODS: Retrospective study of 162 pediatric patients receiving either standard (5-6 mg/kg, n = 90) or nonstandard (>6 mg/kg, n = 72) dosing of IFX during induction was performed. Patient demographics, clinical outcomes, and laboratory data were collected. Need for dose escalation during the first 6 months, combination therapy with immunomodulators, and steroid-free progression were investigated. RESULTS: Clinical remission rates between the 2 groups were significantly different, with patients receiving nonstandard dosing demonstrating higher rates (58% vs 78%; p = 0.012). Use of combination therapy with immunomodulators was significantly different between standard and nonstandard groups (80% vs 48%; p < 0.001). Numeric trend in need for IFX dose escalation in the first 6 months was seen between standard and nonstandard groups (54% vs 39%, respectively; p = 0.087). Post-induction IFX trough concentrations, rates of antibody development, drug discontinuation, and infusion reaction were similar. CONCLUSIONS: Nonstandard induction dosing of IFX was associated with higher rates of clinical remission, despite similar rates of serum IFX trough concentrations. There was a numeric trend towards the standard group requiring dose escalation within the first 6 months of therapy. Patients given nonstandard dosing may achieve superior clinical outcomes compared with those on standard dosing.
RESUMEN
Background Peripheral artery disease (PAD) increases the risk of cardiovascular events and limb events including amputations. PAD is twice as prevalent in Black compared with non-Hispanic White individuals, especially among men. Screening for PAD using the ankle-brachial index in community settings, such as the barbershop, could lead to earlier diagnosis and treatment. Methods and Results A pilot study was conducted at 2 barbershops in Cleveland, OH from June to December 2020 to assess the feasibility of screening for PAD in the barbershop setting and the effect of an educational intervention on PAD awareness. After screening with both automated and Doppler ankle-brachial index, PAD was identified in 5/31 (16.1%) of participants. Baseline systolic blood pressure, low-density lipoprotein cholesterol, and random blood glucose were higher in participants who screened positive for PAD (P<0.001). PAD awareness was low overall. There was a significant improvement in PAD awareness assessment scores obtained at the initial and exit visits (9.93±4.23 to 12.50±4.41, P=0.004). An association was found between PAD awareness at baseline and highest education level achieved: compared with those with some college/associate's degree or higher, non-high school graduates scored lower on PAD awareness (P=0.022), as did those who only had a high school diploma or tests of General Educational Development (P=0.049). Conclusions In a pilot study, barbershop-based screening for PAD among Black men revealed a higher than expected PAD prevalence and low PAD awareness. An educational video was effective at increasing PAD awareness. Ankle-brachial index screening and educational outreach in the barbershop may be a feasible and effective tool to diagnose PAD and reduce PAD disparities among Black men at highest risk.

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of advanced liver disease in the USA. Liver biopsy, the gold standard diagnostic test for evaluating liver fibrosis, is associated with significant risk and expense. The accuracy of ultrasound elastography and Fibrosis-4 index (FIB-4) in the obese NAFLD population is unknown. We aimed to compare the accuracy of ultrasound elastography and FIB-4 to liver biopsy in ruling out cirrhosis in NAFLD patients at a tertiary, transplant referral center in the US. METHODS: We retrospectively evaluated 93 patients with a mean age of 53 years (SD: 13 years) who underwent liver ultrasound elastography and liver biopsy, and additionally calculated their FIB-4 at the time of biopsy. We compared the liver stiffness measurement (LSM) obtained from ultrasound elastography and FIB-4 with the pathology results for ruling out cirrhosis. RESULTS: 85% of the patients were white, 53% were female, average BMI was 34.7 (SD: 6.7), 52% had diabetes, and 53% had hypertension. For biopsy-proven cirrhosis (prevalence 15%), a cut-off value of 12.5 kilopascals (kPa) for F4 had a sensitivity of 92% and a specificity of 54%. Values below this threshold excluded cirrhosis with 98% certainty. Compared to FIB-4, ultrasound elastography showed higher accuracy in ruling out cirrhosis (92% vs. 80% sensitivity, 98% vs. 95% negative predictive value (NPV), respectively). CONCLUSION: To our knowledge, this is the first study in a tertiary transplant referral center in the USA to show that ultrasound elastography was superior to FIB-4 and can be used as a reliable screening test to rule out cirrhosis in obese NAFLD patients at a 12.5 kPa cut-off. Therefore, helping to avoid the risk and expense associated with liver biopsy.
RESUMEN
SIGNIFICANCE: Eosinophilic esophagitis (EoE) is an inflammatory condition characterized by T helper-2 (T H 2) cytokines. Ulcerative colitis (UC) and Crohn disease (CD) are inflammatory conditions with different clinical presentations and immune profiles. UC is associated with T H 2 cytokines and CD with T H 1 cytokines. We investigated potential differences in the association of EoE with UC and CD because of these different immune profiles. METHODS: We utilized ICD-9 and ICD-10 codes to find patients with inflammatory bowel disease (IBD) and EoE. We defined EoE as any esophageal biopsy with >15 eosinophils. We collected demographic, clinical, laboratory, endoscopic, and histological data. RESULTS: Thirty patients had both EoE and IBD. 14.9% of UC patients had EoE and 5.7% of CD patients had EoE. 64.7% of UC patients presented with UC and EoE at the same time, whereas 76.9% of CD patients presented with EoE at follow up. Ten of 13 CD patients were on anti-tumor necrosis factor (TNF) at EoE diagnosis. No UC patients were on anti-TNF at EoE diagnosis. Eighty-three percent of CD patients had mild disease or were in remission, whereas 50% of UC patients had moderate to severe disease at the time of EoE diagnosis. CONCLUSION: A higher percentage of UC than CD patients had EoE. EoE was more likely to be present at the initial diagnosis of UC than CD. EoE was more likely after diagnosis and treatment of CD with anti-TNF, when CD activity was mild or in remission. The difference in presentation suggests that anti-TNF or it's impact on inflammation may differentially impact the association of EoE with CD and UC.

BACKGROUND: The funduscopic examination is an essential component of the neurologic examination. However, examination of the ocular fundus with a direct ophthalmoscope is often difficult. Nonmydriatic ocular fundus photography allows direct visualization of the ocular fundus with high-quality photographs. We used nonmydriatic ocular fundus photography to improve patient care and funduscopy skills of residents in the Neurology Resident Clinic. METHODS: At the time of triage, funduscopic photographs of all new neurology resident clinic patients were taken. The images were imported into the hospital's imaging software. The residents completed a full neurologic examination, including a funduscopic examination with a handheld ophthalmoscope. At the time of staffing the patients with the attendings, the residents received immediate feedback and teaching on retina photograph evaluation. RESULTS: A total of 255 patients were enrolled. Of those, 230 (90%) had at least one high-quality funduscopic photograph. Retinal photographs were normal in 161 (70%). Out of the 69 abnormal photographs, only 7% of abnormalities were detected by the residents. Ninety-three percent of residents found the retinal photographs useful. CONCLUSIONS: Nonmydriatic ocular fundus photography improved the care in patients presenting to a Neurology resident clinic and facilitated residents in recognizing funduscopic findings. Its benefits are clear when one considers (1) the high risk of negative patient outcomes and possible medicolegal consequences due to missed findings, (2) the ease of incorporating retinal photographs into the patients' medical records, and (3) the benefit of improving resident education in regard to the ophthalmologic examination.

OBJECTIVES: Calcaneal fractures often require contralateral, uninjured calcaneus radiographs as a template. The purpose of this study was to establish mean values for calcaneal radiographic parameters in an uninjured urban American population and perform side-by-side comparison with respect to age, sex, laterality, and radiograph obliquity (XRO). DESIGN: Retrospective analysis of consecutive patients. SETTING: Fourteen hospitals including Level 1 trauma center. PATIENTS/PARTICIPANTS: Retrospective review of >800 uninjured patients with bilateral foot and calcaneus radiographs obtained between June and December 2019 was performed. Inclusion criteria were the following: age 18-89 years without fracture; previous foot surgical procedures; radiographic evidence of arthrosis in ankle, hindfoot, or midfoot; osteomyelitis; tumor; or foot deformities. INTERVENTION: The lateral radiographs were independently reviewed by 3 observers, measuring Böhler angle (BA), crucial angle of Gissane (CAG), calcaneal length (CL), calcaneal height (CH), calcaneotalar ratio (CTR), and XRO. MAIN OUTCOME MEASUREMENTS: The mean values of BA, CAG, CL, CH, and CTR were established. Side-by-side comparisons were completed with respect to age, sex, laterality, and XRO. RESULTS: There were no statistically significant differences in side-by-side measurements of the BA, CAG, CL, or CH. XRO had significant effects on the measurements of BA, CAG, CH, and CTR. Side-by-side comparisons showed greater intersubject variability than within-subject differences. CONCLUSIONS: We did not observe any differences in commonly measured calcaneal radiographic parameters. CAG is not a reliable parameter for diagnostic and operative planning purposes. We conclude that the use of contralateral calcaneus radiographs as templates for calcaneus fractures is a valid technique.

RATIONALE: Posttraumatic epilepsy (PTE) is a common cause of morbidity in children after a traumatic brain injury (TBI), occurring in 10-20% of children following severe TBI. PTE is diagnosed after two or more unprovoked seizures occurring 1-week post TBI. More often, studies have focused on children with epilepsy due to severe TBI. We aim to understand the utility of head computed tomography (HCT), EEG, and the risk of developing drug-resistant epilepsy in children after mild TBI. METHOD: We retrospectively studied 321 children with TBI at a tertiary pediatric referral center during a 10-year period. Mild TBI was defined as loss of consciousness (LOC) or amnesia < 30 min, moderate TBI as LOC or amnesia between 30 min and 1 day, and severe TBI as LOC or amnesia > 1 day, subdural hemorrhage, or contusion. Multiple clinical variables were reviewed, including past and present antiepileptic drug(s), seizure control, and mode of injury. First and subsequent post-TBI EEGs/prolonged video-EEGs were obtained acutely, subacutely, and/or chronically (range, day 1-3 years, median 1 month). Descriptive analyses were conducted using medians and ranges for continuous data. Categorical data were reported using frequencies and percentages, while comparisons between groups were made using Fisher's exact test for small sample sizes. RESULTS: Forty-seven children were diagnosed with posttraumatic epilepsy: eight children (17%) due to mild TBI, 39 children (83%) due to severe TBI. For the eight children with mild TBI whom all had an accidental trauma (non-inflicted), the median follow-up time was 25 months (range 1.5 months-84 months). The median age was 10 years (range 4-18 years), and the median age at the time of injury was seven years (range: 23 months-13 years). No relevant previous medical history was present for six patients (80%), and two patients' (20%) relevant previous medical histories were unknown. Seven patients (88%) had no history of seizures, and patient #6 (12%) had unknown seizure history. Six patients (75%) had normal routine EEG(s). Patient #6 (13%) had an abnormal VEEG 3 months after the initial normal routine EEG, while patient #1 (13%) had an initial prolonged EEG 8 months after TBI. Compared to the 39 patients with severe TBI, 31 (79%) of whom had abnormal EEGs (routine and/or prolonged with video), mild TBI patients were more likely to have normal EEGs, p = 0.005. Head CT scans were obtained acutely for seven patients (90%), all of which were normal. One patient only had brain magnetic resonance imaging (MRI) 8 months after the injury. Compared to the 39 patients with severe TBI, all of whom had abnormal HCTs, mild TBI patients were less likely to have abnormal HCTs, p < 0.0001. In patients with mild TBI, no patient had both abnormal EEG/VEEG and HCT, and no one was on more than one Antiepileptic drug (AED), p < 0.005. Six patients (75%) had MRIs, of which five (63%) were normal. Two patients (#1, 7) did not have MRIs, while one patient's (#4) MRI was unavailable. Five patients (63%) had a seizure <24 h post TBI, while the rest had seizures after the first week of injury. CONCLUSION: Children with epilepsy due to mild TBI, loss of consciousness, or amnesia < 30 min are more likely to have normal HCT and EEG and to be on 0-1 AED. Limitations of our study include the small sample size and retrospective design. The current findings add to the paucity of data in children who suffer from epilepsy due to mild TBI.
RESUMEN
OBJECTIVES: To compare the number of patients with gunshot wounds presenting to our level 1 trauma center before and during the COVID-19 pandemic with a focus on volume trends after the lifting of stay-at-home directives through August 2020. DESIGN: Retrospective. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Seven hundred six gunshot wound patients between 2016 and 2020 (months March to September only). INTERVENTION: COVID-19 pandemic and resultant stay at home directives. MAIN OUTCOME MEASUREMENTS: Number of patients presenting with gunshot wounds per time period. RESULTS: The number of patients with gunshot wounds presenting to our institution increased by 11.7% in March-April 2020 and by 67% in May-August 2020 when compared to previous years. Length of stay significantly decreased in 2020 compared to 2018 and 2019. In 2020, significantly fewer patients had orthopaedic procedures than in 2018. CONCLUSIONS: Patients presenting with gunshot wounds increased during the initial "stay-at-home" portion of the pandemic in March to April and increased significantly more after the restrictions were relaxed during May to August.Level of Evidence: Therapeutic Level III.
RESUMEN
Background: Bipolar and depressive disorders (bipolar disorder [BD], major depressive disorder [MDD]), as well as menopause affect millions of women. Although there are three known cognitive behavioral group treatment (CBGT) protocols to help women with problematic menopause symptoms, they do not target women on the BD or MDD spectrum. The purpose of this qualitative study was to learn more about the treatment needs and group experiences of women with problematic menopause symptoms and diagnosed on the BD and MDD spectrum, who participated in a CBGT intervention for menopausal symptoms. Methods: Narrative data recorded by clinicians (Interventionists' notes) and participants (Evaluation of Groups Survey) were analyzed using content analyses. Results: Several themes emerged from (n = 11 BD; n = 48 MDD) what women wanted help with (specific symptoms and general aspects of menopause), what women liked about CBGT (specific and general aspects of the program), and changes needed in the CBGT intervention (things wished for and barriers that interfered with the program). The two diagnostic groups differed in their responses, although both groups identified content and delivery gaps they wished would be addressed. Specifically related to their diagnosis, women most commonly talked about problems with worsening mood and mood instability and multiple stressors interfering with their ability to follow through with the intervention. Conclusions: These findings can help refine existing CBGT protocols for women diagnosed on the BD and MDD spectrum seeking help for menopause symptoms. Trial Registry: Parent study ClinicalTrials.gov [identifier: NCT02860910].
RESUMEN
BACKGROUND: Recently, a skeletal maturity system using knee radiographs, named the modified Roche-Wainer-Thissen (RWT) system, has been developed using 7 discrete radiographic parameters. While the system has been shown to significantly outperform the Greulich and Pyle atlas, the effect of rotational variation of the knee radiograph on skeletal maturity determinations has not been studied. METHODS: Normal knee computed tomography scans of 12 male children ages 10 to 16 years and 8 female children ages 8 to 14 years were obtained retrospectively, converted into 3-dimensional reconstructions, and then used to simulate knee radiographs in 5 different rotational positions. Images were graded using the modified RWT system, and 1-way repeated measures analysis of variance was used to compare skeletal age in the patella centered view versus the other positions. We next retrospectively found 85 pediatric patients with both bilateral standing anteroposterior hip to ankles and separate knee radiograph within 6 months of each other. The skeletal maturity values from the 2 different radiographs were compared in 39 males between the ages of 10 and 16 years and 46 females between 8 and 14 years of age using paired t test and Wilcoxon-signed rank test. RESULTS: On the computed tomography scan-based images, there was no statistically significant effect of rotational position on the modified RWT score using repeat measures analysis of variance (P=0.210). Only the width ratio of the tibial epiphysis and metaphysis and the width ratio of the fibular epiphysis and metaphysis were statistically different between rotational positions (P<0.05). Comparing clinical full length versus knee radiographs, we found a small difference of 0.069 years which trended towards a statistically significant difference (P=0.009). CONCLUSIONS: This retrospective study supports the resilience of the RWT model to rotational variation, reassuring clinicians that bone age estimation can be performed in a slightly rotated knee x-ray within a reasonable margin of error. These results can minimize the number of radiographs needed to assess skeletal maturity limiting radiation exposure and expedite clinical flow. LEVEL OF EVIDENCE: Level-III-diagnostic study.

BACKGROUND: Occasionally specimen containers are received in the dermatopathology laboratory without an accompanying specimen. The consequences in this scenario can range from delay in care and inconvenience to patients to increased morbidity and even mortality. Data regarding incidence and associated characteristics of missing specimens are scant. METHODS: Over a 10-year period (7 January 2010 to 7 January 2020) all cases with a missing specimen in a single academic dermatopathology laboratory and a single dermatopathology practice embedded within a dermatology practice were reviewed. RESULTS: Out of 270,754 specimens received, 83 empty specimen containers were identified for an incidence of 0.031%. There were 14 (0.005%) cases in which patients had a separate procedure and a second container with both specimens in it accompanying the empty container. The most common missing specimen-generating procedures were shave biopsies (51%) with most common clinical diagnosis being unspecified (30%). The most common specimen location from the 97 total specimen bottles containing either zero or two specimens was head/neck (53%). Although no further procedures were performed after the specimen was lost for 48% of cases, re-biopsy occurred for 28%. CONCLUSIONS: Failure to insert specimens into the correct container is rare, but represents a potential significant negative event where vigilance and improvement is required.

From the start of the coronavirus disease 2019 (COVID-19) pandemic, researchers have looked to electronic health record (EHR) data as a way to study possible risk factors and outcomes. To ensure the validity and accuracy of research using these data, investigators need to be confident that the phenotypes they construct are reliable and accurate, reflecting the healthcare settings from which they are ascertained. We developed a COVID-19 registry at a single academic medical center and used data from March 1 to June 5, 2020 to assess differences in population-level characteristics in pandemic and non-pandemic years respectively. Median EHR length, previously shown to impact phenotype performance in type 2 diabetes, was significantly shorter in the SARS-CoV-2 positive group relative to a 2019 influenza tested group (median 3.1 years vs 8.7; Wilcoxon rank sum P = 1.3e-52). Using three phenotyping methods of increasing complexity (billing codes alone and domain-specific algorithms provided by an EHR vendor and clinical experts), common medical comorbidities were abstracted from COVID-19 EHRs, defined by the presence of a positive laboratory test (positive predictive value 100%, recall 93%). After combining performance data across phenotyping methods, we observed significantly lower false negative rates for those records billed for a comprehensive care visit (p = 4e-11) and those with complete demographics data recorded (p = 7e-5). In an early COVID-19 cohort, we found that phenotyping performance of nine common comorbidities was influenced by median EHR length, consistent with previous studies, as well as by data density, which can be measured using portable metrics including CPT codes. Here we present those challenges and potential solutions to creating deeply phenotyped, acute COVID-19 cohorts.

RATIONALE & OBJECTIVE: Low serum magnesium level has been shown to be associated with increased mortality, but its role as a predictor of cardiovascular disease is unclear. This study evaluates the association between serum magnesium level and cardiovascular events and all-cause mortality in a large cohort of individuals with chronic kidney disease (CKD). STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: 3,867 participants with CKD, enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study. EXPOSURES: Serum magnesium measured at study baseline. OUTCOMES: Composite cardiovascular events (myocardial infarction, cerebrovascular accident, heart failure, and peripheral arterial disease) and all-cause mortality. ANALYTICAL APPROACH: Cox proportional hazards models adjusted for demographic, clinical, and laboratory characteristics. RESULTS: During the 14.6 (4.4) years (standard deviation) of follow-up, 1,384 participants died (36/1,000 person-years), and 1,227 (40/1,000 person-years) had a composite cardiovascular event. There was a nonlinear association between serum magnesium level and all-cause mortality. Low and high magnesium levels were associated with greater rates of all-cause mortality after adjusting for demographics, comorbid conditions, medications including diuretics, estimated glomerular filtration rate, and proteinuria (P < 0.001). No significant associations were observed between serum magnesium levels and the composite cardiovascular events. Low serum magnesium level was associated with incident atrial fibrillation (HR, 1.36; 95% CI, 1.01-1.82; P = 0.04). LIMITATIONS: Single measurement of serum magnesium. CONCLUSIONS: In this large CKD cohort, serum magnesium level < 1.9 mg/dL and >2.1 mg/dL was associated with increased risk for all-cause mortality. Low magnesium level was associated with incident atrial fibrillation but not with composite cardiovascular disease events. Further studies are needed to determine the optimal range of serum magnesium in CKD to prevent adverse clinical outcomes.
