High Frequencies of Antiviral Effector Memory T Cells and Memory B Cells Mobilized into Herpes Infected Vaginal Mucosa Associated With Protection Against Genital Herpes.

Vaginal mucosa-resident anti-viral effector memory B- and T cells appeared to play a crucial role in protection against genital herpes. However, how to mobilize such protective immune cells into the vaginal tissue close to infected epithelial cells remains to be determined. In the present study, we investigate whether and how, CCL28, a major mucosal-associated chemokine, mobilizes effector memory B- and T cells in leading to protecting mucosal surfaces from herpes infection and disease.

Combination of Microfocused Ultrasound with Visualization and Dilute Calcium Hydroxylapatite Filler for Moderate to Severe Knee Skin Laxity.

Background: Microfocused ultrasound with visualization (MFU-V) and calcium hydroxylapatite (CaHA) filler are modalities for improving skin laxity. Their use in combination on body sites other than the face is expanding.

Objective: To investigate the effectiveness and safety of combination MFU-V and dilute CaHA (dCaHA) for lower anterior thigh and knee laxity over 12 and 24 weeks.

Adagrasib with or without Cetuximab in Colorectal Cancer with Mutated G12C.

Background: Adagrasib, an oral small-molecule inhibitor of mutant KRAS G12C protein, has shown clinical activity in pretreated patients with several tumor types, including colorectal cancer. Preclinical studies suggest that combining a KRAS G12C inhibitor with an epidermal growth factor receptor antibody could be an effective clinical strategy.

Methods: In this phase 1-2, open-label, nonrandomized clinical trial, we assigned heavily pretreated patients with metastatic colorectal cancer with mutant KRAS G12C to receive adagrasib monotherapy (600 mg orally twice daily) or adagrasib (at the same dose) in combination with intravenous cetuximab once a week (with an initial loading dose of 400 mg per square meter of body-surface area, followed by a dose of 250 mg per square meter) or every 2 weeks (with a dose of 500 mg per square meter).

Knowledge, Perceptions and Photoprotective Behaviors Against the Damaging Effects of Direct, Indirect, and Blue Light: There Are No "Cheat Days".

Objective: We sought to evaluate the impact of the coronavirus-19 (COVID-19) pandemic on sun-seeking and sun-safe behaviors.

Methods: We conducted an online, cross-sectional, population-based survey.

Multicenter Assessment of Cryoanalgesia Use in Minimally Invasive Repair of Pectus Excavatum: A 20-center Retrospective Cohort Study.

Objective: To assess the clinical implications of cryoanalgesia for pain management in children undergoing minimally invasive repair of pectus excavatum (MIRPE).

Background: MIRPE entails significant pain management challenges, often requiring high postoperative opioid use. Cryoanalgesia, which blocks pain signals by temporarily ablating intercostal nerves, has been recently utilized as an analgesic adjunct.

Adagrasib in Non-Small-Cell Lung Cancer Harboring a Mutation.

Background: Adagrasib, a KRAS inhibitor, irreversibly and selectively binds KRAS, locking it in its inactive state. Adagrasib showed clinical activity and had an acceptable adverse-event profile in the phase 1-1b part of the KRYSTAL-1 phase 1-2 study.

Methods: In a registrational phase 2 cohort, we evaluated adagrasib (600 mg orally twice daily) in patients with -mutated non-small-cell lung cancer (NSCLC) previously treated with platinum-based chemotherapy and anti-programmed death 1 or programmed death ligand 1 therapy.

Two Phase 3 Trials of Baricitinib for Alopecia Areata.

Background: Alopecia areata is an autoimmune condition characterized by rapid hair loss in the scalp, eyebrows, and eyelashes, for which treatments are limited. Baricitinib, an oral, selective, reversible inhibitor of Janus kinases 1 and 2, may interrupt cytokine signaling implicated in the pathogenesis of alopecia areata.

Methods: We conducted two randomized, placebo-controlled, phase 3 trials (BRAVE-AA1 and BRAVE-AA2) involving adults with severe alopecia areata with a Severity of Alopecia Tool (SALT) score of 50 or higher (range, 0 [no scalp hair loss] to 100 [complete scalp hair loss]).

Heart's eyes to see color: Cardiac vagal tone modulates the impact of ethnicity on selected attention under high load.

The present study tested whether cardiac vagal activity-which is known to play a vital role in social cognition and engagement-predicted the impact of faces of other ethnicity on selective attention under load. Based on the neurovisceral integration theory, we hypothesized that participants with higher resting heart rate variability (HRV) would exhibit better task performance of a target detection task in trials with face distractors of other ethnicity than participants with lower resting HRV, when cognitive resources were scarce under high load. Caucasian participants were instructed to detect a target letter among letter strings superimposed on Black or White male distractor faces under high and low perceptual load.

Twelve-month clinical outcomes after implantation of a new, modular, anterior shape-changing fluid optic intraocular lens.

Purpose: To report the initial safety and effectiveness profile for an anterior shape-changing, modular IOL, Juvene IOL (JIOL), for the treatment of aphakia and presbyopia after removal of the natural crystalline lens due to cataract.

Setting: 2 private practices in Monterrey and Tijuana, Mexico.

Design: Exploratory prospective multicenter open-label noncomparative clinical trial.

Maximizing clinical rotation placements for US medical students: exploring an optimization model.

Background: For years, US medical schools have relied on community-based, private clinicians to educate medical students. There has been a steady decline in the number of physicians willing to take on medical students in their clinical practices. Recent issues related to the pandemic raise questions about how many patients students should see to have a meaningful clinical experience.

Pathways of Microcirculatory Endothelial Dysfunction in Obstructive Sleep Apnea: A Comprehensive Ex Vivo Evaluation in Human Tissue.

Background: The mechanism and markers of cardiovascular disease (CVD) in obstructive sleep apnea (OSA) remain unknown. The microcirculation is the site of early changes in OSA patients who are free of CVD risk.

Methods: Patients with newly diagnosed moderate to severe OSA (n = 7) were studied before and 12 weeks after intensive treatment with continuous positive airway pressure (CPAP), along with weight and age matched controls (n = 7).

Data automated bag breathing unit for COVID-19 ventilator shortages.

Background: The COVID-19 pandemic has caused a global mechanical ventilator shortage for treatment of severe acute respiratory failure. Development of novel breathing devices has been proposed as a low cost, rapid solution when full-featured ventilators are unavailable. Here we report the design, bench testing and preclinical results for an 'Automated Bag Breathing Unit' (ABBU).

The Modulation of Cardiac Vagal Tone on Attentional Orienting of Fair-Related Faces: Low HRV is Associated with Faster Attentional Engagement to Fair-Relevant Stimuli.

The current experiment examined the effect of fair-related stimuli on attentional orienting and the role of cardiac vagal tone indexed by heart rate variability (HRV). Neutral faces were associated with fair and unfair offers in the Ultimatum Game (UG). After the UG, participants performed the spatial cueing task in which targets were preceded by face cues that made fair or unfair offers in the UG.

Treatment of allosensitized patients receiving allogeneic transplantation.

Donor-specific anti-HLA antibodies (DSAs) are a major cause of engraftment failure in patients receiving haploidentical stem cell transplantation (HaploSCT). Effective treatments are needed for these patients, who often have no other donor options and/or are in need to proceed urgently to transplantation. We studied a multimodality treatment with alternate-day plasma exchange (PE), rituximab, intravenous γ globulin (IVIg) and an irradiated donor buffy coat for patients with DSAs at 2 institutions.

The Critical Role of Growth Factors in Gastric Ulcer Healing: The Cellular and Molecular Mechanisms and Potential Clinical Implications.

In this article we review the cellular and molecular mechanisms of gastric ulcer healing. A gastric ulcer (GU) is a deep defect in the gastric wall penetrating through the entire mucosa and the muscularis mucosae. GU healing is a regeneration process that encompasses cell dedifferentiation, proliferation, migration, re-epithelialization, formation of granulation tissue, angiogenesis, vasculogenesis, interactions between various cells and the matrix, and tissue remodeling, all resulting in scar formation.

Cutting Through the Noise: Predictors of Successful Online Message Retransmission in the First 8 Months of the COVID-19 Pandemic.

In this paper, we investigate how message construction, style, content, and the textual content of embedded images impacted message retransmission over the course of the first 8 months of the coronavirus disease 2019 (COVID-19) pandemic in the United States. We analyzed a census of public communications (n = 372,466) from 704 public health agencies, state and local emergency management agencies, and elected officials posted on Twitter between January 1 and August 31, 2020, measuring message retransmission via the number of retweets (ie, a message passed on by others), an important indicator of engagement and reach. To assess content, we extended a lexicon developed from the early months of the pandemic to identify key concepts within messages, employing it to analyze both the textual content of messages themselves as well as text included within embedded images (n = 233,877), which was extracted via optical character recognition.

Combination Therapy Using Radiofrequency Microneedling and Corticosteroids for Hypertrophic Scars: A Case Report.

Dysregulated scar formation can cause hypertrophic scarring, a difficult entity to treat. Although fractionated lasers are a popular therapy for hypertrophic scars, laser-induced epidermal damage might cause pigmentary changes in individuals with darker skin tones. Radiofrequency microneedling delivers ablative energy directly to the dermis and is safe for use in such patients.

Psychophysiological concomitants of personality pathology in development.

Psychophysiological research methods allow important insights into normative and pathological functioning of the human organism. This position paper briefly reviews existing studies, investigating the psychophysiological concomitants of personality pathology, with an emphasis on developmental aspects. Focussing on measures, indexing autonomic nervous system (ANS) activity at rest, and its reactivity to experimental challenge, the narrative synthesis of the literature highlights current challenges in the field.

A Double-Filter Provision for Expanded Red Flag Laws: A Proposal for Balancing Rights and Risks in Preventing Gun Violence.

In response to the continued expansion of "red flag" laws allowing broader classes of people to petition a court for the removal of firearms from individuals who exhibit dangerous conduct, this paper argues that state laws should adopt a double-filter provision that balances individual rights and government public safety interests. The main component of such a provision is a special statutory category - "reporting party" - that enables a broader social network, such as co-workers or school administrators, to request that a law enforcement officer file a petition for an Extreme Risk Protection Order (ERPO). A double-filter provision would not give reporting parties a right to file a court petition directly.

A Model for Exploring Compatibility Between Applicants and Residency Programs: Right Resident, Right Program.

Holistic review of residency applications is touted as the gold standard for selection, yet vast application numbers leave programs reliant on screening using filters such as United States Medical Licensing Examination scores that do not reliably predict resident performance and may threaten diversity. Applicants struggle to identify which programs to apply to, and devote attention to these processes throughout most of the fourth year, distracting from their clinical education. In this perspective, educators across the undergraduate and graduate medical education continuum propose new models for student-program compatibility based on design thinking sessions with stakeholders in obstetrics and gynecology education from a broad range of training environments.

Impaired vasodilation in pregnant African Americans: Preliminary evidence of potential antecedents and consequences.

Significant health disparities exist between African Americans (AA) and European Americans (EA) in hypertension and hypertension-related disorders. Evidence suggests that this is due to impaired vasodilation in AAs. Pregnancy is a potent systemic vasodilatory state.

Principles And Policies To Strengthen Child And Adolescent Health And Well-Being.

Four recent reports from the National Academies of Sciences, Engineering, and Medicine framed around the issues of poverty; mental, emotional, and behavioral health; adolescence; and young family health and education build on extensive recent evidence of what can be done to improve the health and well-being of children, youth, and families. We describe the process of generating the reports, briefly summarize each report's content, and identify crosscutting themes and recommendations. We also note how the coronavirus disease 2019 (COVID-19) pandemic highlights major disparities and systemic problems addressed in the reports and heightens the relevance of their policy recommendations.

Después de la tormenta: Collective trauma following Hurricane Maria in a northeastern Puerto Rican community in the United States.

Hurricane Maria was the largest disaster in Puerto Rico's history, affecting Puerto Rican communities throughout the United States. We conducted focus groups using a grounded theory approach with adults displaced from Puerto Rico to a northeastern community 12 (n = 5) and 17 months (n = 7) postdisaster. Key informant interviews were also conducted with nine community advocates working with displaced hurricane survivors.
