Subclinical Atherosclerosis Across the Menopausal Transition in Women With and Without HIV.

The menopausal transition is a pivotal time of cardiovascular risk, but knowledge is limited in HIV. We studied longitudinal carotid artery intima-media thickness (CIMT) in the Women's Interagency HIV Study (2004-2019; 979 women/3247 person-visits; 72% with HIV). Among women with HIV only, those who transitioned had greater age-related CIMT progression compared to those remaining premenopausal (difference in slope = 1.64 µm/year, P = .002); and CIMT increased over time in the pretransition (3.47 µm/year, P = .002) and during the menopausal transition (9.41 µm/year, P < .0001), but not posttransition (2.9 µm/year, P = .19). In women with HIV, menopause may accelerate subclinical atherosclerosis as measured by CIMT.

Pre-pandemic Metabolic Correlates of COVID-19 Severity and Long COVID Incidence in People Living with HIV.

Host metabolic dysregulation, especially in tryptophan metabolism, is intricately linked to COVID-19 severity and its post-acute sequelae (Long COVID). People living with HIV (PLWH) experience similar metabolic dysregulation and face an increased risk of developing Long COVID. However, whether pre-existing HIV-associated metabolic dysregulations contribute in predisposing PLWH to severe COVID-19 outcomes remains underexplored. Analyzing pre-pandemic samples from PLWH with documented post-infection outcomes, we found specific metabolic alterations, including increased tryptophan catabolism, predicting an elevated risk of severe COVID-19 and the incidence of Long COVID. These alterations warrant further investigation for their potential prognostic and mechanistic significance in determining COVID-19 complications.

Hypertension burden, treatment, and control among people with HIV at a clinical care center in the Southeastern US, 2014-2019.

Hypertension management outcomes in people with HIV (PWH) are not well characterized, despite high hypertension burden. We assessed hypertension prevalence, incidence, treatment, and outcomes among patients with HIV at a clinical center in the southeastern US, from 2014 to 2019. To identify characteristics associated with treatment and outcomes, we estimated adjusted risk ratios (aRR) and 95% confidence intervals (CI). Among 2274 patients, 72% were cisgender men, 56% non-Hispanic Black, median age 47 years, 48% MSM, 12% had CD4 cell count <200 cells/µl, 72% HIV RNA level <400 copies/mL and 39% prevalent hypertension. Hypertension incidence rate was 6.3/100 person-years (95% CI, 5.6-7.0). Among incident hypertension cases (n = 275), 16% (95% CI, 11-20) initiated an antihypertensive within one year. Compared to non-Hispanic white patients, Hispanic (aRR, 6.68; 95% CI, 1.50-29.74) and non-Hispanic Black patients (aRR, 2.18; 95% CI, 0.91-5.24) were more likely to initiate an antihypertensive. Among patients initiating an antihypertensive (n = 178), 63% (95% CI 56-70) experienced blood pressure control within one year. Patients with HIV experienced a high burden of hypertension with notable delays in antihypertensive initiation, as well as gaps in achieving blood pressure control, highlighting opportunities for interventions designed to minimize delays in controlling hypertension in this vulnerable population.

Stable Latent HIV Infection and Low-level Viremia Despite Treatment With the Broadly Neutralizing Antibody VRC07-523LS and the Latency Reversal Agent Vorinostat.

We tested the combination of a broadly neutralizing HIV antibody with the latency reversal agent vorinostat (VOR). Eight participants received 2 month-long cycles of VRC07-523LS with VOR. Low-level viremia, resting CD4+ T-cell-associated HIV RNA (rca-RNA) was measured, and intact proviral DNA assay (IPDA) and quantitative viral outgrowth assay (QVOA) were performed at baseline and posttreatment. In 3 participants, IPDA and QVOA declines were accompanied by significant declines of rca-RNA. However, no IPDA or QVOA declines clearly exceeded assay variance or natural decay. Increased resistance to VRC07-523LS was not observed. This combination therapy did not reduce viremia or the HIV reservoir. Clinical Trials Registration. NCT03803605.

Microscopic colitis in Northern Ireland: an updated clinicopathological audit and assessment of compliance with European guidelines.

AIM: We previously reported the first population-based study of the epidemiology of microscopic colitis in Northern Ireland. The aim of the current study is to provide updated data on incidence, diagnostic methods and clinicopathological associations, following dissemination of the previous report. A further aim was to compare the findings against relevant recommendations from the 2020 European guidelines. METHOD: Study cases were identified via the Belfast Health and Social Care Trust pathology laboratory system for new cases of collagenous colitis or lymphocytic colitis diagnosed from 2017 to 2020 inclusive. Demographic and clinical information was collated from electronic healthcare records. RESULTS: Two hundred and seventeen new diagnoses of microscopic colitis were made between 2017 and 2020, comprising 89 (41%) collagenous colitis and 128 (59%) lymphocytic colitis. The overall incidence of microscopic colitis, expressed per 100,000 adult population, ranged from 7.6 to 11.5 (5.9 to 9.0 per 100,000 total population). The 2019 peak of 11.5 cases per 100,000 adult population represents a 71.6% increase in incidence compared with the mean incidence of 6.7 per 100,000 adult population from previous data for 2008-2016. There has also been a significant increase in number of cases diagnosed on separate sampling from the right and left colon (85% in 2019-2020 compared with 30% in 2008-2016; p < 0.001). Overall compliance with coeliac serology testing has improved, with 89% tested in 2017-2018 compared with 75% in 2008-2016. CONCLUSION: Clinicopathological communication has contributed to an increased incidence of microscopic colitis in Northern Ireland through better endoscopic diagnostic sampling and pathology coding practices. Coeliac serology testing has also improved, although continued clinical awareness is required of the need for coeliac serology testing in all patients diagnosed with microscopic colitis.

A call for unity in DEIJ efforts using a proposed framework for Education, Recruitment, Retainment, Research, and Active outreach (ERA) for genetic counselors in the United States.

Genetic counselors, like many other healthcare providers, play a vital role in genomic health care. As a profession, we, along with our colleagues and students, have recognized the need to improve and incorporate diversity, equity, inclusion, and justice (DEIJ) within our daily ways of practice to help create access to genomic technologies. In order to create systemic change and focus on unity, open communication, and transparency, we introduce a suggested framework called ERA (Education, Recruitment, Retainment, Research, and Active Outreach). This framework would benefit a genetic counselor throughout various stages of their career, from student to practicing genetic counselor, and can be broadly applied to all specialties of genomic medicine. Different iterations of DEIJ efforts have arisen in the National Society of Genetic Counselors (NSGC), from the D&I (Diversity and Inclusion) Task Force to the J.E.D.I (justice, equity, diversity, and inclusion) committee. The lack of recorded history of these previous efforts and the lack of communication between current DEIJ organizations is one of the many reasons the ERA framework demands unity and transparency to achieve sustainable positive change. Genetic counselors must unite and work collaboratively to conduct and promote DEIJ efforts, so the benefits of genomic medicine can be realized by all.

Consonant Age of Acquisition Reveals Nonlinear Effects in Nonword Repetition Performance.

Recent work has shown significant sublexical effects of long-term memory in nonword repetition (NWR) using a dichotomous consonant age of acquisition (CAoA) variable (Moore, 2018; Moore, Fiez, and Tompkins, 2017). Performance consistently decreased when stimuli comprised consonants acquired later versus earlier in speech development. To address potential confounds related to stimulus design and linearity, the purpose of this study was to test whether performance decreases as the CAoA value of stimuli increases in various linguistic tasks using a continuous CAoA variable. Thirty-one college students completed NWR and other linguistic tasks in which the stimuli varied in average CAoA values. Data were analyzed using multilevel modeling. After accounting for phonotactic probability, CAoA was a statistically significant predictor of performance across the models reported. The relationship was more complex in some of the models in which CAoA showed a statistically significant nonlinear relationship with the outcome measure. Results from this study support previous work showing that CAoA affects performance on NWR and other linguistic tasks that vary in their memory, auditory perceptual, and articulatory demands. Importantly, this line of work was extended here by demonstrating that the CAoA effect is robust across novel stimulus sets and study designs, and may be more complex than previously understood when using a dichotomous CAoA variable. Quadratic results suggest that the CAoA variable has a differential effect on performance for low to moderate CAoA values, but for higher CAoA values the effect is similarly negative. The nonlinear relationship between CAoA and measures of speed and accuracy on some of the tasks warrants further study into the complex relationship between various predictive factors that contribute to language performance.

Spectral degradation influences phonological memory in typically hearing adults.

Phonological processing is a fundamental component of language, can be impaired in people with hearing loss, and involves several confounded subprocesses. The purpose of this study was to systematically examine several phonological subprocesses - i.e., the spectral quality of auditory input and phonological short-term and long-term memory - in order to better understand how they interact with one another in basic linguistic tasks. Using an experimental, within-subjects design, 30 typically-hearing adults completed nonword repetition (NWR) and auditory lexical decision (ALD) tasks varying in spectral quality (normal versus spectrally-degraded), consonant age of acquisition (CAoA; i.e. early-acquired versus late-acquired consonants), syllable length (NWR task), and lexical status (ALD task). In NWR, spectral degradation muted the word length effect, though performance differed depending on how familiar participants were with the degraded stimuli. ALD findings showed that the magnitude of the degradation effect varied between stimuli comprising early-acquired versus late-acquired consonants. The robust effect of spectral degradation on phonological short-term and long-term memory provides a model of the interactive nature of these subprocesses in typical adults. Future work with populations with hearing loss can provide a comparison to help understand how the typical and clinical phonological systems differ.

Innovations in Human Immunodeficiency Virus (HIV) Care Delivery During the Coronavirus Disease 2019 (COVID-19) Pandemic: Policies to Strengthen the Ending the Epidemic Initiative-A Policy Paper of the Infectious Diseases Society of America and the HIV Medicine Association.

The goal of the Ending the HIV Epidemic Initiative is to reduce new infections in the United States by 90% by 2030. Success will require fundamentally changing human immunodeficiency virus (HIV) prevention and care delivery to engage more persons with HIV and at risk of HIV in treatment. While the coronavirus disease 2019 (COVID-19) pandemic reduced in-person visits to care facilities and led to concern about interruptions in care, it also accelerated growth of alternative options, bolstered by additional funding support. These included the use of telehealth, medication delivery to the home, and increased flexibility facilitating access to Ryan White HIV/AIDS Program services. While the outcomes of these programs must be studied, many have improved accessibility during the pandemic. As the pandemic wanes, long-term policy changes are needed to preserve these options for those who benefit from them. These new care paradigms may provide a roadmap for progress for those with other chronic health issues as well.

Switching to Intranasal Esketamine Maintains the Antidepressant Response to Intravenous Racemic Ketamine Administration: A Case Series of 10 Patients.

PURPOSE: This study aims to assess the efficacy and safety of intranasal (IN) esketamine as maintenance antidepressant therapy in patients who have demonstrated clinical improvement with off-label intravenous (IV) racemic ketamine for treatment-resistant depression (TRD). METHODS: This is a retrospective case series of 10 consecutive outpatients with TRD who all had a clinically meaningful response when treated with IV racemic ketamine and were then switched to IN esketamine for maintenance therapy. Patient outcomes were assessed with the Montgomery-Åsberg Depression Rating Scale, Patient Health Questionnaire 9, and Clinical Global Impression of Improvement scale at each visit. Adverse effects were assessed at each treatment. FINDINGS: Results indicated that 9 patients either maintained the benefit or showed greater improvement when transitioned to IN esketamine for antidepressant maintenance therapy. One patient had worsening of depression due to an acute psychosocial stressor but still improved from baseline IV racemic ketamine treatment. Six patients returned to work or pursued employment, and 4 patients with suicidal ideation remitted during IV racemic ketamine treatment and had no recurrence of suicidality with IN esketamine. No serious adverse reactions or tolerability issues were observed. IMPLICATIONS: This case series reports the outcomes of 10 severely ill patients with TRD who had a clinically meaningful response to IV racemic ketamine and demonstrated a maintenance of effect or continued improvement when transitioned to IN esketamine. Although this finding needs to be replicated in larger, controlled studies, this report provides promising results for patients who have safely and effectively switched to Food and Drug Administration-approved IN esketamine after receiving acute or maintenance depression treatment with off-label IV racemic ketamine.

Impact on colorectal cancer pathology reporting practice of migration from TNM 5 to TNM 8.

AIMS: The introduction of TNM 8 into UK pathology practice in January 2018 considers tumour deposits in colorectal cancer staging for the first time. The impact of this new classification on pathology reporting practices has yet to be evaluated. METHODS AND RESULTS: A clinical audit was conducted, comparing consecutive colorectal cancer resection specimens reported under TNM 5 classification guidelines in 2017 (n = 177) and TNM 8 guidelines in 2018 (n = 234). Tumour features (venous invasion, perineural invasion, lymph node metastatic disease, tumour deposits) and changes in reporting practices were evaluated among four specialist gastrointestinal pathologists working within a large pathology department. Adoption of TNM 8 practice led to an approximate doubling in the use of ancillary stains (41.0% of TNM 8 versus 22.0% of TNM 5 cases, P < 0.001) to help evaluate tumours. A narrowing of the range between pathologists was observed in reporting cases as having one or more form of regional, extramural, discontinuous tumour (TNM 5 range = 50.0-79.0%, TNM 8 range = 57.8-65.7%), with no change in the overall proportion of cases reported as such (62.7% versus 62.4%, P = 0.95). However, significant interobserver variation in reporting rates for individual parameters remained. CONCLUSION: TNM 8 colorectal cancer staging offers potentially greater reproducibility in pathology reporting of regional, extramural, discontinuous disease with similar proportions of patients reported as having one or more of these forms of tumour spread compared with TNM 5. Further guidance in defining individual features is required to reduce interobserver variation in pathology assessments and to help elucidate the clinical significance of each parameter.

Uterine Endometrial Stromal Tumors With Limited Infiltration: First Report of a Case Series Indicating Potential for Malignant Behavior.

The distinction between a uterine endometrial stromal nodule (ESN) and low-grade endometrial stromal sarcoma (LGESS) is based on the nature of the interface between the lesion and the surrounding myometrium and the presence or absence of vascular invasion. Most LGESS exhibit widespread irregular myometrial invasion with or without vascular invasion, whereas ESNs are well-circumscribed without vascular invasion. Tavassoli and Norris proposed that minor marginal irregularity (up to 3 protrusions, each <3 mm beyond the main mass) is allowable in an ESN and these criteria have been incorporated into the World Health Organization Classification. There is a small group of neoplasms with marginal irregularity greater than that allowable in ESN but without the widespread myometrial infiltration typical of most LGESS. Such neoplasms have been categorized as endometrial stromal tumor with limited infiltration but there have been no studies which have provided follow-up in this group of neoplasms. We aimed to determine the clinical behavior of this uncommon group of neoplasms. From a series of 19 endometrial stromal tumors with limited infiltration, mainly from consultation practice, we obtained follow-up information in 16 cases by contacting referring pathologists and clinicians. The patient age ranged from 32 to 84 yr (median: 54 yr) and follow-up ranged from 16 to 187 mo (median: 52 mo). Two of 16 patients (12.5%) developed metastatic disease to the small intestine and peritoneum (1 case-metastasis at 23 mo) and bone and lung (1 case-humeral metastasis at 135 mo; lung and sacral metastases subsequently). No patient died from disease during the follow-up period. A small percentage of endometrial stromal tumors with limited infiltration exhibit malignant behavior with distant metastasis. Such neoplasms should be regarded as potentially malignant and the term LGESS with limited infiltration is an appropriate designation.

A Randomized, Double-blinded, Placebo-controlled Trial of Sitagliptin for Reducing Inflammation and Immune Activation in Treated and Suppressed Human Immunodeficiency Virus Infection.

BACKGROUND: Dipeptidyl peptidase-4 (DPP-4) inhibitors have pleotropic anti-inflammatory and immune regulatory effects in addition to glucoregulation. We evaluated inflammation and immune markers in suppressed human immunodeficiency virus (HIV) infection during treatment with the DPP-4 inhibitor sitagliptin. METHODS: Virologically suppressed adults with HIV without diabetes on stable antiretroviral therapy (ART) with ≥100/µL CD4 cells were randomized to 16 weeks of sitagliptin 100 mg/day vs placebo in a multicenter trial. The primary endpoint was the change in plasma soluble CD14 (sCD14) from baseline to week 15-16. RESULTS: Ninety participants were randomized, and 42 from each arm were included in per-protocol analyses. Participants were 45% non-Hispanic white, 38% non-Hispanic black, and 15% Hispanic, with a median age of 51 years; 83% were male; and the median CD4 count was 602 cells/µL. At week 15-16, there was no difference in sCD14 change between the 2 arms (P = .69). Relative to placebo, the sitagliptin arm had 47% greater decline in CXCL10 (95% confidence interval, -57% to -35%) at week 15 (P < .001). There were no significant between-arm differences in other soluble biomarkers, total CD4 and CD8 counts, or markers of lymphocyte or monocyte activation. Sitagliptin was well tolerated. CONCLUSIONS: Sixteen weeks of sitagliptin had no effect on sCD14 levels in virologically suppressed participants with HIV. CXCL10, a chemokine involved in atherogenesis that predicts non-AIDS events during ART, declined markedly with sitagliptin. This suggests that DPP-4 inhibition has the potential to reduce cardiovascular morbidity in treated HIV infection. CLINICAL TRIALS REGISTRATION: NCT01426438.

Fibroadenoma-like Lesion of the Vagina: A Description of 2 Cases of a Previously Unreported Entity.

We report 2 cases of a previously undescribed vaginal lesion, which we term "fibroadenoma-like lesion of the vagina" because of the close morphologic resemblance to breast fibroadenoma. Both lesions arose in the upper vagina and exhibited a biphasic appearance with benign epithelial and stromal elements. The glandular epithelium comprised a double layer of luminal and basal cells with focal squamous differentiation in 1 case. The stromal component was fibroblastic and morphologically bland for the most part, although occasional atypical symplastic-like cells were present in 1 case. Both lesions exhibited a similar immunophenotype with the luminal and basal glandular epithelium expressing PAX8 and GATA3 while estrogen receptor and progesterone receptor were largely negative. The basal cell layer was p63 and CK5/6 positive. We discuss the possible origin and histogenesis of this rare lesion which we believe to be benign based on the morphologic features and uneventful 5 years follow-up in 1 case.

Uterine tumour resembling ovarian sex cord tumour: first report of a large series with follow-up.

AIMS: Uterine tumour resembling ovarian sex cord tumour (UTROSCT) is an uncommon mesenchymal neoplasm of uncertain histogenesis. While it is considered a neoplasm of uncertain but low malignant potential, there is limited evidence for this as there are no large studies with follow-up. We aimed to determine the clinical behaviour of this uncommon neoplasm and investigate clinicopathological parameters which predict behaviour. METHODS AND RESULTS: From a series of 34 cases of UTROSCT, mainly from consultation practice, we obtained follow-up information which was obtained by contacting referring pathologists and clinicians. The follow-up periods ranged from 6 to 135 months (mean 39 months). Eight of 34 patients (23.5%) developed extrauterine metastasis to a variety of sites, including pelvic and abdominal peritoneum, ovary, lymph nodes, bone, liver and lung, and three patients (8.8%) died of tumour. Those neoplasms which exhibited malignant behaviour occurred on average in older patients, and were larger and more likely to exhibit necrosis, lymphovascular invasion, cervical involvement, significant nuclear atypia and significant mitotic activity. However, only the presence of necrosis and significant mitotic activity was statistically significant. CONCLUSIONS: While our figure of 23.5% of cases exhibiting malignant behaviour may reflect some bias related to consultation practice our results show that, not uncommonly, these neoplasms have an aggressive clinical course with extrauterine metastasis. Given the overlap in pathological parameters between clinically benign and malignant neoplasms, UTROSCTs are all best regarded as potentially malignant.

Fusiform Gyrus Laterality in Writing Systems with Different Mapping Principles: An Artificial Orthography Training Study.

Writing systems vary in many ways, making it difficult to account for cross-linguistic neural differences. For example, orthographic processing of Chinese characters activates the mid-fusiform gyri (mFG) bilaterally, whereas the processing of English words predominantly activates the left mFG. Because Chinese and English vary in visual processing (holistic vs. analytical) and linguistic mapping principle (morphosyllabic vs. alphabetic), either factor could account for mFG laterality differences. We used artificial orthographies representing English to investigate the effect of mapping principle on mFG lateralization. The fMRI data were compared for two groups that acquired foundational proficiency: one for an alphabetic and one for an alphasyllabic artificial orthography. Greater bilateral mFG activation was observed in the alphasyllabic versus alphabetic group. The degree of bilaterality correlated with reading fluency for the learned orthography in the alphasyllabic but not alphabetic group. The results suggest that writing systems with a syllable-based mapping principle recruit bilateral mFG to support orthographic processing. Implications for individuals with left mFG dysfunction will be discussed.

Modeling Psychological Functioning in Refugees.

BACKGROUND: Refugee trauma survivors often experience posttraumatic stress disorder, other anxiety disorders, depression, and somatization. As a result, many suffer a disproportionate vulnerability to a variety of interpersonal, health, and social problems. OBJECTIVE: The study purpose was to develop a preliminary predictive model identifying high-risk refugee trauma survivors based on levels of trauma and psychological functioning. METHOD: A subset of 449 Somali and Oromo refugee trauma survivors was randomly selected from a larger study for secondary data analysis. Data from the PTSD Checklist-Civilian version, the Revised Hopkins Symptom Checklist, and the Sheehan Disability Inventory contributed to a psychological functioning score. A researcher-developed survey contributed to a composite trauma score. RESULTS: Predictors associated with functioning level differed by gender. Of interest, caring for children and increasing coping strategies were related to lower functioning in women. The regression relationship between trauma and functioning was linear in men but quadratic in women. CONCLUSION: Understanding the mechanisms linking trauma and function is implicated in the assessment of risk among trauma survivors. Predictive models inform the effective psychosocial interventions targeting those at greatest risk.

Validation of Medicaid Claims-based Diagnosis of Myocardial Infarction Using an HIV Clinical Cohort.

BACKGROUND: In nonexperimental comparative effectiveness research using health care databases, outcome measurements must be validated to evaluate and potentially adjust for misclassification bias. We aimed to validate claims-based myocardial infarction (MI) algorithms in a Medicaid population using an HIV clinical cohort as the gold standard. METHODS: Medicaid administrative data were obtained for the years 2002-2008 and linked to the UNC CFAR HIV Clinical Cohort based on social security number, first name, and last name and MI were adjudicated. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS: There were 1063 individuals included in the study. Over a median observed time of 2.5 years, 17 had an MI. Specificity ranged from 0.979 to 0.993 with the highest specificity obtained using the ICD-9 code 410.xx in the primary or secondary position and a length of stay >3 days. Sensitivity of MI ascertainment varied from 0.588 to 0.824 depending on algorithm. CONCLUSIONS: Specificities of varying claims-based MI ascertainment criteria are high but small changes impact positive predictive value in a cohort with low incidence. Sensitivities vary based on ascertainment criteria. Type of algorithm used should be prioritized based on study question and maximization of specific validation parameters that will minimize bias while also considering precision.
