Post traumatic stress and sleep disorders in long COVID: Patient management and treatment.

Post traumatic stress disorder (PTSD) and sleep disorders are prevalent among patients with long COVID. The intersection of PTSD and/or sleep disorders with long COVID is complex. Thus, use of a biopsychosocial lens for assessment and treatment along with a trauma-informed approach to clinical care is recommended. This review provides an overview of the literature on PTSD and sleep disorders among patients with long COVID, including prevalence rates, risk factors, and potential pathophysiology. Pharmacological and non-pharmacological treatment options are reviewed. Also, we provide actionable steps clinicians can integrate into their practice to help effectively assess and treat PTSD and sleep disorders, including validated symptom assessments, recommended referrals, and specific components of non-pharmacological interventions.

"Advocates for Each Other": The creation and evaluation of a pragmatic peer navigation program for black patients in primary care with uncontrolled hypertension.

BACKGROUND: Black individuals in the U.S. and in our primary care clinic experience worse control of blood pressure compared to White individuals. OBJECTIVE: To address this inequity, our objectives were to (1) elicit from patients and community members their ideas for barriers and facilitators to blood pressure control; and (2) use their input to design and pilot a navigator program for Black patients in our clinic to improve blood pressure management. PATIENT INVOLVEMENT: We conducted three focus groups with 27 individuals and identified two main areas of need that informed the peer navigator program: (1) community-based services and (2) skill development for hypertension self-management. METHODS: Peer navigators from the Black community called participants at least monthly for 6-12 months and connected them with medical and social services. Available blood pressure data was used as the primary outcome to measure change pre- to post-peer navigation program. RESULTS: Among 499 eligible patients in the clinic, 53 (10.6%) enrolled in the peer navigation program. For those with baseline and follow-up blood pressure data, mean systolic blood pressure decreased from 155.9 to 142.4 mmHg after the program (change of -13.6, 95% CI -24.7 to -2.4) for the enrolled patients (N = 17) and from 139.1 to 137.1 mmHg (change of -2.5, -4.8 to 1.9) for unenrolled, comparison patients (N = 183). DISCUSSION: This community-informed peer navigation program to support Black patients with uncontrolled hypertension led to a 11.1 mmHg greater decrease in average systolic blood pressure for enrolled patients compared to the comparison group. However, the enrolled group started with a significantly higher systolic blood pressure at baseline with more room for improvement. While this study was conducted during the pandemic years, low uptake of this program needs to be addressed in expansion efforts. PRACTICAL VALUE: Clinic-based peer navigation for hypertension improved blood pressure control and was highly regarded by the subset of enrolled patients. Increasing uptake and sustainable funding for non-billable clinic roles remain areas of need. FUNDING: Grant from the Pacific Hospital Preservation & Development Authority.

Electronic Consults for Infectious Diseases in a United States Multisite Academic Health System.

We launched Infectious Disease electronic consultations (eConsults) in 2018. During the first 15.5 months, primary care practitioners submitted 328 eConsults; the most frequent reasons were a positive culture or polymerase chain reaction (PCR) result, syphilis, and latent tuberculosis. Practitioners commonly requested advice on antimicrobial choice, clinical evaluation, and indications for treatment. Internal phone consultations decreased after eConsult implementation.

Association of mitochondrial allele 4216C with increased risk for sepsis-related organ dysfunction and shock after burn injury.

Impaired mitochondrial activity has been linked to increased risk for clinical complications after injury. Furthermore, variant mitochondrial alleles have been identified and are thought to result in decreased mitochondrial activity. These include a nonsynonymous mitochondrial polymorphism (T4216C) in the nicotinamide adenine dinucleotide dehydrogenase 1 gene (ND1), encoding a key member of complex I within the electron transport chain, which is found almost exclusively among Caucasians. We hypothesized that burn patients carrying ND1 4216C are less able to generate the cellular energy necessary for an effective immune response and are at increased risk for infectious complications. The association between 4216C and outcome after burn injury was evaluated in a cohort of 175 Caucasian patients admitted to the Parkland Hospital with burns covering greater than or equal to 15% of their total body surface area or greater than or equal to 5% full-thickness burns under an institutional review board-approved protocol. To remove confounding unrelated to burn injury, individuals were excluded if they presented with significant non-burn-related trauma (Injury Severity Score > or =16), traumatic or anoxic brain injury, spinal cord injury, were HIV/AIDS positive, had active malignancy, or survived less than 48 h postadmission. Within this cohort of patients, carriage of the 4216C allele was significantly associated by unadjusted analysis with increased risk for sepsis-related organ dysfunction or septic shock (P = 0.011). After adjustment for full-thickness burn size, inhalation injury, age, and sex, carriage of the 4216C allele was associated with complicated sepsis (adjusted odds ratio = 3.7; 95% confidence interval, 1.5-9.1; P = 0.005), relative to carriers of the T allele.

Could Beta blockade improve outcome after injury by modulating inflammatory profiles?

BACKGROUND: Cardioprotection with beta-receptor antagonists improves outcome in high risk patients undergoing elective surgery. Recent trials have demonstrated an association between beta blocker (BB) use and improved outcomes after injury. The mechanisms through which BB result in improved outcomes remain poorly elucidated. In vitro evidence supports that BB modulates the postinjury inflammatory response. The purpose of this study was to examine the effects of BB on inflammatory profiles in injured patients at increased risk for heart disease. METHODS: A pseudo-randomized, controlled trial of injured patients over 55 admitted to the intensive care unit was conducted. Patients were randomized to receive continuous BB or standard of care. Patients with a reported history of prehospital BB use were enrolled into an observational arm of the trial, continued on BB, and analyzed with the continuous BB group. Plasma interleukin (IL)-6 and IL-1beta levels were measured by enzyme-linked immunosorbent assay at baseline and day 1, 2, and 4 after BB initiation. Cytokine data were log transformed for normality assumptions. Repeated measures analysis of variance was used to test for within-group differences in cytokine levels over time. RESULTS: Forty-two patients were enrolled. Seventeen patients were randomized to the control group and 25 patients received continuous BB (10 randomized/15 observational). There was no difference in gender, age, prior history of heart disease, or admission heart rate, systolic blood pressure or initial base deficit between groups. Baseline levels of IL-6 and IL-1beta did not differ between groups. Levels of IL-6, but not IL-1beta, decreased over time in patients receiving BB (p = 0.04), whereas levels in controls remained unchanged (p = 0.27). There were no BB related complications. CONCLUSIONS: Use of BB decreases serum IL-6 levels over time in injured patients at risk for heart disease. This may contribute to improved outcomes noted in trauma patients receiving BB. Additionally, BB use in this population of patients is safe after endpoints of resuscitation have been met.

Site-isolated luminescent europium complexes with polyester macroligands: metal-centered heteroarm stars and nanoscale assemblies with labile block junctions.

The synthesis of a series of polymeric Eu(III) complexes with polyester ligands, along with supporting emission spectra, luminescence lifetimes, and, for a Eu block copolymer film, atomic force microscopy (AFM) data, is presented. Dibenzoylmethane was derivatized with a hydroxyl initiator site (dbmOH, 1) for tin octoate catalyzed ring opening polymerization of dl-lactide. The resulting poly(lactic acid) macroligand, dbmPLA (2), was combined with EuCl3 to generate Eu(dbmPLA)3 (3). Chelation of both dbmPLA and a polycaprolactone-functionalized bipyridine ligand (bpyPCL2) led to the Eu(III)-centered heteroarm star Eu(dbmPLA)3(bpyPCL2) (4). Unpolarized emission spectra and luminescence lifetimes were recorded for the Eu polymers in CH2Cl2 and for Eu(dbmPLA)3, as a film. Solution data for Eu(dbm)3 and Eu(dbm)3(bpy) were collected for comparison. For Eu tris(dbm) complexes, data were fit to a double exponential decay, indicating the presence of multiple species. Relative amounts of the longer lifetime component increase in the series Eu(dbm)3 solutions to Eu(dbmPLA)3 solutions to Eu(dbmPLA)3 films, perhaps suggesting benefits of the "polymer shell effect" and the diminishment of aquo adducts known to shorten lifetimes. As with the nonpolymeric analogue, data for Eu(dbmPLA)3(bpyPCL2) fit to a single-exponential decay. The sharpness of the feature at 579.7 nm, attributable to the 5D0 --> 7F0 transition in the emission spectrum of 4, lends further support for a homogeneous sample. AFM studies of "as cast" thin films of 4 reveal a lamellar structure with a 17.5 nm repeat. These microstructures, inferred to contain Eu luminophores at the glassy PLA-crystalline PCL domain interfaces, are modified by thermal treatment.
