Disparities in the experience of chronic musculoskeletal pain in the United States stem from a confluence of a broad array of factors. Organized within the National Institute on Aging Health Disparity Research Framework, a literature review was completed to evaluate what is known and what is needed to move chronic musculoskeletal pain research forward specific to disproportionately affected populations. Peer-reviewed studies published in English, on human adults, from 2000 to 2019, and conducted in the United States were extracted from PubMed and Web of Science. Articles were reviewed for key words that focused on underrepresented ethnic/race groups with chronic musculoskeletal pain applying health factor terms identified in the NIAHealth Disparity Research Framework four levels of analysis 1) environmental, 2) sociocultural, 3) behavioral, and 4) biological. A total of 52 articles met inclusion criteria. There were limited publications specific to underrepresented ethnic/race groups with chronic musculoskeletal pain across all levels with particular research gaps under sociocultural and biological categories. Current limitations in evidence may be supplemented by a foundation of findings specific to the broader topic of "chronic pain" which provides guidance for future investigations. Study designs including a focus on protective factors and multiple levels of analyses would be particularly meritorious. PERSPECTIVE Chronic musculoskeletal pain unequally burdens underrepresented ethnic/race groups. In order to move research forward and to systematically investigate the complex array of factors contributing toward health disparities, an organized approach is necessary. Applying the NIA Health Disparities Research Framework, an overview of the current state of evidence specific to chronic musculoskeletal pain and underrepresented ethnic/race groups is provided with future directions identified.Escherichia coli-based whole-cell biocatalysts are widely used for the sustainable production of value-added chemicals. However, weak acids present as substrates and/or products obstruct the growth and fermentation capability of E. coli. Here, we show that a viroporin consisting of the influenza A matrix-2 (M2) protein, is activated by low pH and has proton channel activity in E. coli. The heterologous expression of the M2 protein in E. coli resulted in a significant increase in the intracellular pH and cell viability in the presence of various weak acids with different lengths of carbon chains. In addition, the feasibility of developing a robust and efficient E. coli-based whole-cell biocatalyst via introduction of the proton-selective viroporin was explored by employing (Z)-11-(heptanolyoxy)undec-9-enoic acid (ester) and 2-fucosyllactose (2'-FL) as model products, whose production is hampered by cytosolic acidification. The engineered E. coli strains containing the proton-selective viroporin exhibited approximately 80% and 230% higher concentrations of the ester and 2'-FL, respectively, than the control strains without the M2 protein. The simple and powerful strategy developed in this study can be applied to produce other valuable chemicals whose production involves substrates and/or products that cause cytosolic acidification.
Hematoma is a complication of cardiac implantable electronic device (CIED) procedures and may lead to device infection. The TYRX antibacterial envelope reduced major CIED infection by 40% in the randomized WRAP-IT (World-wide Randomized Antibiotic Envelope Infection Prevention Trial) study, but its effectiveness in the presence of hematoma is not well understood.

The purpose of this study was to evaluate the incidence and infectious consequences of hematoma and the association between envelope use, hematomas, and major CIED infection among WRAP-IT patients.

All 6800 study patients were included in this analysis (control 3429; envelope 3371). Hematomas occurring within 30 days postprocedure (acute) were characterized and grouped by study treatment and evaluated for subsequent infection risk. Data were analyzed using Cox proportional hazard regression modeling.

Acute hematoma incidence was 2.2% at 30 days, with no significant difference between treatment groups (envelope vs control hazard ratio [HR] 1.15; 95% confidence interval [CI] 0.84-1.58; P = .39). Through all follow-up, the risk of major infection was significantly higher among control patients with hematoma vs those without (13.1% vs 1.6%; HR 11.3; 95% CI 5.5-23.2; P <.001). The risk of major infection was significantly lower in the envelope vs control patients with hematoma (2.5% vs 13.1%; HR 0.18; 95% CI 0.04-0.85; P = .03).

The risk of hematoma was 2.2% among WRAP-IT patients. Among control patients, hematoma carried a >11-fold risk of developing a major CIED infection. This risk was significantly mitigated with antibacterial envelope use, with an 82% reduction in major CIED infection among envelope patients who developed hematoma compared to control.

Data regarding uterine artery embolization (UAE) to specifically treat anticoagulant-associated iatrogenic abnormal uterine bleeding (AUB-I) are sparse. This manuscript aimed to quantify the effectiveness of UAE in treating this subset of patients.

Retrospective case series.

Academic hospital serving a large minority-majority population.

Twenty-four patients with AUB-I that was provoked or aggravated by the initiation of anticoagulation therapy.

Treatment of anticoagulant-associated AUB-I that failed medical management or was acute with UAE rather than inferior vena cava filter placement and hysterectomy.

An imaging database search was performed to identify patients who underwent UAE for anticoagulant-associated AUB-I from May 2011 to July 2020. Medical and radiologic records were reviewed. Short- and long-term outcomes were obtained to date, ranging from 10 months to 10 years after the procedure. In total, 24 patients were identified, ranging in age from 35 to 54 (mean 44.9) years. Venous thrombong while allowing the continuation of anticoagulation therapy, with high rates of uterine preservation and preserved menses.
To assess the accuracy of C-reactive protein (CRP) in predicting early postoperative complications in patients undergoing elective laparoscopic shaving for rectosigmoid deep infiltrating endometriosis (DIE).

A single-center observational retrospective cohort study.

Third-level referral center for endometriosis.

A total of 294 patients were included in the study. All of them underwent elective laparoscopic shaving for rectosigmoid DIE.

Postoperative CRP levels (assessed from day 3 onward, every 48 hours, until hospital discharge) and early postoperative complications were reviewed to assess CRP as a predictive marker of postoperative complications.

The study outcomes were the association between early postoperative complications and CRP levels, the optimal CRP cutoff, and its predictive accuracy. Twenty-five patients (8.5%) experienced early postoperative complications. Five patients with postoperative complications within 2 days of surgery were excluded from the analysis. selleck kinase inhibitor On postoperative day 3 th (95% CI, 90.1-99.7), and an area under the receiver operating characteristic curve of 75.0% (95% CI, 61.9-80.1) and 85.6% (95% CI, 74.1-96.5), respectively.

CRP on postoperative day 5 seemed to be a moderately accurate predictive marker of early postoperative complications in the patients who had undergone elective laparoscopic shaving for rectosigmoid DIE.

To present a series of patients diagnosed with oculocutaneous albinism (OCA) based on clinical presentation who were later proven to have a different diagnosis.

The medical records of patients seen at the Pediatric Inherited Eye Disease Clinic of the University of Iowa from 1980 to 2018 who were eventually discovered to have an incorrect diagnosis of OCA were reviewed retrospectively.

Eight pediatric patients presenting with clinical features suggestive of OCA which changed to a different diagnosis over time were identified. Presenting clinical features included fair pigmentation of the skin and adnexa (8/8), congenital nystagmus (6/8), decreased visual acuity (8/8), iris transillumination defects (8/8), and foveal hypoplasia (7/8). Of the 8 patients, 4 manifested progressive, preschool-age-onset myopia. Other associated clinical features included hearing loss (3), seizures (1), abnormal chest x-ray (1) and easy bruising (2). During follow-up, additional clinical features and genetic testing proved that they have different clinical entities, namely, Knobloch syndrome, Jeune syndrome, Donnai-Barrow syndrome, Waardenburg syndrome, Aniridia syndrome, Stickler syndrome, and Hermansky-Pudlak syndrome, one of the syndromic types of OCA.

Clinical features used to diagnose OCA also occur in other disorders. For a definitive diagnosis of OCA, ancillary/genetic testing must be performed. Clinical features not typically found in association with albinism, such as hearing loss, or early onset, or progressive myopia, may indicate the need for more extensive investigation.

Complete and accurate pathology reports are vital to postoperative prognostication and management. We evaluated the impact of three interventions across a diverse group of hospitals on pathology reports of postresection NSCLC.

We evaluated pathology reports for patients who underwent curative-intent surgical resection for NSCLC, at 11 institutions within four contiguous Dartmouth Hospital Referral Regions in Arkansas, Mississippi, and Tennessee from 2004 to 2020, for completeness and accuracy, before and after the following three quality improvement interventions education (feedback to heighten awareness); synoptic reporting; and a lymph node specimen collection kit. We compared the proportion of pathology reports with the six most important items for postoperative management (specimen type, tumor size, histologic type, pathologic [p] T-category, pN-category, margin status) across the following six patient cohorts preintervention control, postintervention with four different combinations of interventions, and a contemporaneous nonintervention external control.

In the postintervention era, the odds of reporting all key items were eight times higher than those in the preintervention era (OR= 8.3, 95% confidence interval [CI] 6.7-10.2, p < 0.0001). There were sixfold and eightfold increases in the odds of accurate pT- and pN-category reporting in the postintervention era compared with the preintervention era (pT OR= 5.7, 95% CI 4.7-6.9; pN OR= 8.0, 95% CI 6.5-10.0, both p < 0.0001). Within the intervention groups, the odds of reporting all six key items, accurate pT category, and accurate pN-category were highest in patients who received all three interventions.

Gaps in the quality of NSCLC pathologic reportage can be identified, quantified, and corrected by rationally designed interventions.
