Background The incidence of cervical cancer has decreased by 70% since the 1950s. Preventative measures include vaccination against HPV strains and Papanicolaou tests. Early identification of cervical cancer through routine screening can significantly improve patient outcomes. Materials and methods At our academic institution, Community Internal Medicine (CIM) Clinic, 63% of female patients aged 21–65 were compliant with cervical cancer screening. The opening of the ‘Saturday Pap Smear Clinic’ sought to address barriers by offering non-traditional appointment times on Saturday mornings with an all female staff. Our aim was to increase the cervical cancer screening rate by 1% within 12 weeks. Our team compared CIM (intervention) and family medicine (FM) (control) compliance rates from September 2021 to January 2022. Messages were sent to the patient indicating non-compliance and offering options to complete screening. Results At the start of this study, 5239 CIM patients were cervical cancer screening non-compliant. Postintervention, cervical screening rates among non-compliant women within CIM improved by 1.2%. The intervention cohort, CIM patients, had a significant improvement in compliance compared with the control group, FM patients. White women between the ages of 50 and 65 comprised the majority of patients who used the ‘Saturday Pap Smear Clinic’. Conclusions The availability of Saturday appointments for cervical cancer screening completion can enhance cervical cancer screening compliance among eligible women. Eliminating barriers for women can improve health outcomes.

ABSTRACT Estrogen regulates bone mass in women and men, but the underlying cellular mechanisms of estrogen action on bone remain unclear. Although both estrogen receptor (ER)α and ERβ are expressed in bone cells, ERα is the dominant receptor for skeletal estrogen action. Previous studies using either global or cell‐specific ERα deletion provided important insights, but each of these approaches had limitations. Specifically, either high circulating sex steroid levels in global ERα knockout mice or the effects of deletion of ERα during growth and development in constitutive cell‐specific knockout mice have made it difficult to clearly define the role of ERα in specific cell types in the adult skeleton. We recently generated and characterized mice with tamoxifen‐inducible ERα deletion in osteocytes driven by the 8‐kb Dmp1 promoter (ERαΔOcy mice), revealing detrimental effects of osteocyte‐specific ERα deletion on trabecular bone volume (−20.1%) and bone formation rate (−18.9%) in female, but not male, mice. Here, we developed and characterized analogous mice with inducible ERα deletion in osteoclasts using the Cathepsin K promoter (ERαΔOcl mice). In a study design identical to that with the previously described ERαΔOcy mice, adult female, but not male, ERαΔOcl mice showed a borderline (−10.2%, p = 0.084) reduction in trabecular bone volume, no change in osteoclast numbers, but a significant increase in serum CTx levels, consistent with increased osteoclast activity. These findings in ERαΔOcl mice differ from previous studies of constitutive osteoclast‐specific ERα deletion, which led to clear deficits in trabecular bone and increased osteoclast numbers. Collectively, these data indicate that in adult mice, estrogen action in the osteocyte is likely more important than via the osteoclast and that ERα deletion in osteoclasts from conception onward has more dramatic skeletal effects than inducible osteoclastic ERα deletion in adult mice. © 2023 The Authors.

ObjectiveMicrotubule‐associated protein tau (MAPT) mutations cause frontotemporal lobar degeneration, and novel biomarkers are urgently needed for early disease detection. We used task‐free functional magnetic resonance imaging (fMRI) mapping, a promising biomarker, to analyze network connectivity in symptomatic and presymptomatic MAPT mutation carriers.MethodsWe compared cross‐sectional fMRI data between 17 symptomatic and 39 presymptomatic carriers and 81 controls with (1) seed‐based analyses to examine connectivity within networks associated with the 4 most common MAPT‐associated clinical syndromes (ie, salience, corticobasal syndrome, progressive supranuclear palsy syndrome, and default mode networks) and (2) whole‐brain connectivity analyses. We applied K‐means clustering to explore connectivity heterogeneity in presymptomatic carriers at baseline. Neuropsychological measures, plasma neurofilament light chain, and gray matter volume were compared at baseline and longitudinally between the presymptomatic subgroups defined by their baseline whole‐brain connectivity profiles.ResultsSymptomatic and presymptomatic carriers had connectivity disruptions within MAPT‐syndromic networks. Compared to controls, presymptomatic carriers showed regions of connectivity alterations with age. Two presymptomatic subgroups were identified by clustering analysis, exhibiting predominantly either whole‐brain hypoconnectivity or hyperconnectivity at baseline. At baseline, these two presymptomatic subgroups did not differ in neuropsychological measures, although the hypoconnectivity subgroup had greater plasma neurofilament light chain levels than controls. Longitudinally, both subgroups showed visual memory decline (vs controls), yet the subgroup with baseline hypoconnectivity also had worsening verbal memory and neuropsychiatric symptoms, and extensive bilateral mesial temporal gray matter decline.InterpretationNetwork connectivity alterations arise as early as the presymptomatic phase. Future studies will determine whether presymptomatic carriers' baseline connectivity profiles predict symptomatic conversion. ANN NEUROL 2023;94:632–646

Abstract Background: While cigarette smoking has declined among the U.S. general population, sale and use of non-cigarette alternative tobacco products (ATP; e.g., e-cigarettes, cigars) and dual use of cigarettes/ATPs are rising. Little is known about ATP use patterns in cancer survivors enrolled in clinical trials. We investigated prevalence of tobacco product use, and factors associated with past 30-day use, among patients with cancer in national trials. Methods: Cancer survivors (N = 756) enrolled in 9 ECOG-ACRIN clinical trials (2017–2021) completed a modified Cancer Patient Tobacco Use Questionnaire (C-TUQ) which assessed baseline cigarette and ATP use since cancer diagnosis and in the past 30 days. Results: Patients were on average 59 years old, 70% male, and the mean time since cancer diagnosis was 26 months. Since diagnosis, cigarettes (21%) were the most common tobacco product used, followed by smokeless tobacco use (5%), cigars (4%), and e-cigarettes (2%). In the past 30 days, 12% of patients reported smoking cigarettes, 4% cigars, 4% using smokeless tobacco, and 2% e-cigarettes. Since cancer diagnosis, 5.5% of the sample reported multiple tobacco product use, and 3.0% reported multiple product use in the past 30 days. Males (vs. females; OR 4.33; P = 0 < 0.01) and individuals not living with another person who smokes (vs. living with; OR, 8.07; P = 0 < 0.01) were more likely to use ATPs only versus cigarettes only in the past 30 days. Conclusions: Among patients with cancer, cigarettes were the most prevalent tobacco product reported. Impact: Regardless, ATPs and multiple tobacco product use should be routinely assessed in cancer care settings.

ObjectivesTo 1) determine the types and frequency of complications within 3 months following ultrasound‐guided surgical procedures, and 2) identify any patient demographics, co‐morbidities, or procedural characteristics that were associated with an increased risk of complications.MethodsA retrospective chart review was performed at six Sports Medicine clinics across the United States. The Clavien‐Dindo classification was used to categorize procedural complications on a 5‐point scale from 1, representing any deviation in post‐procedure care without requiring pharmacological or invasive treatment to 5, representing death. Generalized Estimating Equations for binomial outcomes with a logit link were used to estimate the overall and procedure‐specific 3‐month complication rates.ResultsAmong 1902 patients, 8.1% (n = 154) had diabetes and 6.3% (n = 119) were current smokers. The analysis included 2,369 procedures, which were performed in either the upper extremity (44.1%, n = 1045) or lower extremity (55.2%, n = 1308) regions. The most common procedure was ultrasound‐guided tenotomy (69.9%, n = 1655). Additional procedures included, trigger finger release (13.1%, n = 310), tendon scraping (8.0%, n = 189), carpal tunnel release (5.4%, n = 128), soft tissue release (2.1%, n = 50), and compartment fasciotomy (1.6%, n = 37). Overall, there was a complication rate of 1.2% (n = 29 complications; 95% CI: 0.8–1.7%). Individual procedures had complication rates that ranged from 0 to 2.7%. There were 13 Grade I complications in 13 patients, 12 Grade II complications in 10 patients, 4 Grade III complications in 4 patients, and 0 Grade IV or V complications. No associations between complication risk and any patient demographics (age, sex, BMI), co‐morbidities (diabetes, smoker), or procedure characteristics (type, region) were identified.ConclusionThis retrospective review provides an evidence‐based estimate supporting the low level of risk associated with ultrasound‐guided surgical procedures for patients from a variety of geographical settings who are seeking care at private and academic‐affiliated clinics.

Abstract Importance and Objective Gastroesophageal reflux disease (GERD) is a chronic condition associated with several risk factors, but little is known about the association between hormone therapy (HT) and GERD in postmenopausal women. Evidence Review We investigated the association between ever or current menopausal HT use and GERD using a systematic review and meta-analysis. Studies published between 2008 and August 31, 2022, were pooled using a DerSimonian and Laird random-effects model, and outcomes were reported as adjusted odds ratios (aOR) with a corresponding 95% CI. Findings The pooled analysis of five studies found a significant direct association between estrogen use and GERD (aOR, 1.41; 95% CI, 1.16-1.66; I 2 = 97.6%), and progestogen use and GERD (two studies: aOR, 1.39; 95% CI, 1.15-1.64; I 2 = 0.0%). The use of combined HT was also associated with GERD (1.16; 95% CI, 1.00-1.33; I 2 = 87.9%). Overall, HT use was associated with 29% higher odds for GERD (aOR, 1.29; 95% CI, 1.17-1.42; I 2 = 94.8%). The large number of pooled participants, differences in study design, geography, patient characteristics, and outcome assessment resulted in significant high heterogeneity. Conclusions and Relevance There is a significant association between ever or current HT use and GERD. However, the results should be interpreted with caution, given the small number of included studies and high heterogeneity. This warrants careful evaluation of GERD risk factors when prescribing HT to reduce the risk of potential GERD complications.

Total joint arthroplasty (TJA) implants are composed of metals, ceramics, and/or polyethylene. Studies suggest that the debris released from metal implants may possess neurotoxic properties with reports of neuropsychiatric symptoms and memory deficits, which could be relevant to Alzheimer’s disease and related dementias. This exploratory study examined the cross-sectional correlation of blood metal concentrations with cognitive performance and neuroimaging findings in a convenience sample of 113 TJA patients with history of elevated blood metal concentrations of either titanium, cobalt and/or chromium. Associations with neuroimaging measures were observed but not with cognitive scores. Larger studies with longitudinal follow-up are warranted.

Abstract The link between bipolar disorder (BP) and immune dysfunction remains controversial. While epidemiological studies have long suggested an association, recent research has found only limited evidence of such a relationship. To clarify this, we investigated the contributions of immune-relevant genetic factors to the response to lithium (Li) treatment and the clinical presentation of BP. First, we assessed the association of a large collection of immune-related genes (4,925) with Li response, defined by the Retrospective Assessment of the Lithium Response Phenotype Scale (Alda scale), and clinical characteristics in patients with BP from the International Consortium on Lithium Genetics (ConLi+Gen, N = 2,374). Second, we calculated here previously published polygenic scores (PGSs) for immune-related traits and evaluated their associations with Li response and clinical features. We found several genes associated with Li response at p < 1x10− 4 values, including HAS3, CNTNAP5 and NFIB. Network and functional enrichment analyses uncovered an overrepresentation of pathways involved in cell adhesion and intercellular communication, which appear to converge on the well-known Li-induced inhibition of GSK-3β. We also found various genes associated with BP’s age-at-onset, number of mood episodes, and presence of psychosis, substance abuse and/or suicidal ideation at the exploratory threshold. These included RTN4, XKR4, NRXN1, NRG1/3 and GRK5. Additionally, PGS analyses suggested serum FAS, ECP, TRANCE and cytokine ligands, amongst others, might represent potential circulating biomarkers of Li response and clinical presentation. Taken together, our results support the notion of a relatively weak association between immunity and clinically relevant features of BP at the genetic level.

PURPOSEThere are numerous barriers to enrollment in oncology biomarker-driven studies.METHODSThe ELAINE 2 study (ClinicalTrials.gov identifier: NCT04432454 ) is an open-label phase 2 study of lasofoxifene combined with abemaciclib in patients with advanced or metastatic estrogen receptor–positive/human epidermal growth factor receptor 2–negative breast cancer with an ESR1 mutation. ELAINE 2 opened clinical sites by using a Traditional approach, which activated a site before patient identification, and the Tempus TIME Trial network, which opened a site only after identifying an eligible patient. This manuscript presents the operational metrics comparing the Traditional and TIME Trial site data.RESULTSThe study enrolled patients over 34 weeks and 16 sites (six Traditional and 10 TIME Trial) participated. Duration for full clinical trial agreement execution for Traditional sites and TIME Trial sites averaged 200.5 (range, 142-257) and 7.6 days (range, 2-14), respectively. Institutional review board approval time for Traditional sites and TIME Trial sites was 27.5 (range, 12-71) and 3.0 days (range, 1-12), respectively. Duration from study activation to first consent was 33.3 (range, 18-58) and 8.8 days (range, 1-35) for Traditional and TIME Trial sites, respectively. The first patient on study was at a TIME Trial site 115 days before a Traditional site and the first seven patients enrolled were at TIME Trial sites. Traditional sites consented 23 and enrolled 16 patients, while TIME Trial sites consented 16 and enrolled 13. The trial enrolled 29 patients in 8.5 months with the anticipated enrollment duration being 12-18 months.CONCLUSIONThe TIME Trial network opened earlier and enrolled the first study patients. These results demonstrate that the Just-in-TIME model, along with a Traditional model, can improve enrollment in biomarker-driven studies.
