Adding Patient-reported Outcomes to the American College of Surgeons National Surgical Quality Improvement Program: Results of the First 33,842 Patients From 65 Hospitals.

OBJECTIVE: To investigate the initial set of patient-reported outcomes (PROs) in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) and their associations with 30-day surgical outcomes. BACKGROUND: PROs provide important information that can be used to improve routine care and facilitate quality improvement. The American College of Surgeons conducted a demonstration project to capture PROs into the NSQIP to complement clinical data. METHODS: From February 2020 to March 2023, 65 hospitals collected Patient-Reported Outcomes Measurement Information System measures assessing global health, pain interference, fatigue, and physical function from patients accrued into the NSQIP. Using multivariable mixed regression, we compared the scores of patients with and without 30-day complications and further analyzed scores exceeding 1-SD worse than national benchmarks. RESULTS: Overall, 33842 patients completed the Patient-Reported Outcomes Measurement Information System measures with a median of 58 days (IQR: 47-72) postoperatively. Among patients without complications (n = 31210), 33.9% had PRO scores 1-SD worse than national benchmarks. Patients with complications were 1.7 times more likely to report worse PROs (95% CI: 1.6-1.8). Patients with complications had lower scores for global physical health [adjusted mean difference (AMD): 2.6, 95% CI: 2.2-3.0], lower for global mental health (AMD: 1.8, 95% CI: 1.4-2.2), higher for pain interference (AMD: 2.4, 95% CI: 2.0-2.8), higher fatigue (AMD: 2.7, 95% CI: 2.3-3.1), and lower physical function (AMD: 3.2, 95% CI: 2.8-3.5). CONCLUSIONS: Postoperative complications negatively affect multiple key dimensions of patients' health-related quality of life. PROs were well below national benchmarks for many patients, even among those without complications. Identifying solutions to improve PROs after surgery remains a tremendous quality improvement opportunity.

New Onset Geriatric Syndromes and One-year Outcomes Following Elective Gastrointestinal Cancer Surgery.

OBJECTIVE: To assess whether older adults who develop geriatric syndromes following elective gastrointestinal surgery have poorer 1-year outcomes. BACKGROUND: Within 10 years, 70% of all cancers will occur in older adults ≥65 years old. The rise in older adults requiring major surgery has brought attention to age-related complications termed geriatric syndromes. However, whether postoperative geriatric syndromes are associated with long-term outcomes is unclear. METHODS: A population-based retrospective cohort study using the New York State Cancer Registry and the Statewide Planning and Research Cooperative System was performed including patients >55 years with pathologic stage I-III esophageal, gastric, pancreatic, colon, or rectal cancer who underwent elective resection between 2004 and 2018. Those aged 55 to 64 served as the reference group. The exposure of interest was a geriatric syndrome [fracture, fall, delirium, pressure ulcer, depression, malnutrition, failure to thrive, dehydration, or incontinence (urinary/fecal)] during the surgical admission. Patients with any geriatric syndrome within 1 year of surgery were excluded. Outcomes included incident geriatric syndrome, 1-year days alive and out of the hospital, and 1-year all-cause mortality. RESULTS: In this study, 37,998 patients with a median age of 71 years without a prior geriatric syndrome were included. Of those 65 years or more, 6.4% developed a geriatric syndrome. Factors associated with an incident geriatric syndrome were age, alcohol/tobacco use, comorbidities, neoadjuvant therapy, ostomies, open surgery, and upper gastrointestinal cancers. An incident geriatric syndrome was associated with a 43% higher risk of 1-year mortality (hazard ratio, 1.43; 95% confidence interval, 1.27-1.60). For those aged 65+ discharged alive and not to hospice, a geriatric syndrome was associated with significantly fewer days alive and out of hospital (322 vs 346 days, P < 0.0001). There was an indirect relationship between the number of geriatric syndromes and 1-year mortality and days alive and out of the hospital after adjusting for surgical complications. CONCLUSIONS: Given the increase in older adults requiring major surgical intervention, and the establishment of geriatric surgery accreditation programs, these data suggest that morbidity and mortality metrics should be adjusted to accommodate the independent relationship between geriatric syndromes and long-term outcomes.

Ecological divergence of wild birds drives avian influenza spillover and global spread.

The diversity of influenza A viruses (IAV) is primarily hosted by two highly divergent avian orders: Anseriformes (ducks, swans and geese) and Charadriiformes (gulls, terns and shorebirds). Studies of IAV have historically focused on Anseriformes, specifically dabbling ducks, overlooking the diversity of hosts in nature, including gull and goose species that have successfully adapted to human habitats. This study sought to address this imbalance by characterizing spillover dynamics and global transmission patterns of IAV over 10 years at greater taxonomic resolution than previously considered. Furthermore, the circulation of viral subtypes in birds that are either host-adapted (low pathogenic H13, H16) or host-generalist (highly pathogenic avian influenza-HPAI H5) provided a unique opportunity to test and extend models of viral evolution. Using Bayesian phylodynamic modelling we uncovered a complex transmission network that relied on ecologically divergent bird hosts. The generalist subtype, HPAI H5 was driven largely by wild geese and swans that acted as a source for wild ducks, gulls, land birds, and domestic geese. Gulls were responsible for moving HPAI H5 more rapidly than any other host, a finding that may reflect their long-distance, pelagic movements and their immuno-naïve status against this subtype. Wild ducks, long viewed as primary hosts for spillover, occupied an optimal space for viral transmission, contributing to geographic expansion and rapid dispersal of HPAI H5. Evidence of inter-hemispheric dispersal via both the Pacific and Atlantic Rims was detected, supporting surveillance at high latitudes along continental margins to achieve early detection. Both neutral (geographic expansion) and non-neutral (antigenic selection) evolutionary processes were found to shape subtype evolution which manifested as unique geographic hotspots for each subtype at the global scale. This study reveals how a diversity of avian hosts contribute to viral spread and spillover with the potential to improve surveillance in an era of rapid global change.

Host barriers to SARS-CoV-2 demonstrated by ferrets in a high-exposure domestic setting.

Ferrets (Mustela putorius furo) are mustelids of special relevance to laboratory studies of respiratory viruses and have been shown to be susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and onward transmission. Here, we report the results of a natural experiment where 29 ferrets in one home had prolonged, direct contact and constant environmental exposure to two humans with symptomatic disease, one of whom was confirmed positive for SARS-CoV-2. We observed no evidence of SARS-CoV-2 transmission from humans to ferrets based on viral and antibody assays. To better understand this discrepancy in experimental and natural infection in ferrets, we compared SARS-CoV-2 sequences from natural and experimental mustelid infections and identified two surface glycoprotein Spike (S) mutations associated with mustelids. While we found evidence that angiotensin-converting enzyme II provides a weak host barrier, one mutation only seen in ferrets is located in the novel S1/S2 cleavage site and is computationally predicted to decrease furin cleavage efficiency. These data support the idea that host factors interacting with the novel S1/S2 cleavage site may be a barrier in ferret SARS-CoV-2 susceptibility and that domestic ferrets are at low risk of natural infection from currently circulating SARS-CoV-2. We propose two mechanistically grounded hypotheses for mustelid host adaptation of SARS-CoV-2, with possible effects that require additional investigation.

Low Preoperative Serum Creatinine is Common and Associated With Poor Outcomes After Nonemergent Inpatient Surgery.

OBJECTIVE: To assess the association between low preoperative serum creatinine and postoperative outcomes. BACKGROUND: The association between low creatinine and poor surgical outcomes is not well understood. METHODS: We identified patients with creatinine in the 7 days preceding nonemergent inpatient surgery in the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2020. Multivariable logistic regression was used to examine the association between creatinine and 30-day mortality and major complications. RESULTS: Of 1,809,576 patients, 27.8% of males and 23.5% of females had low preoperative serum creatinine, 14.6% experienced complications, and 1.2% died. For males, compared with the reference creatinine of 0.85 to 1.04, those with serum creatinine ≤0.44 had 55% increased odds of mortality [ adjusted odds ratio (aOR), 1.55; 95% CI, 1.29-1.86] and 82% increased odds of major complications (aOR, 1.82; 95% CI, 1.69-1.97). Similarly, for females, compared with the reference range of 0.65 to 0.84, those with serum creatinine ≤0.44 had 49% increased odds of mortality (aOR, 1.49; 95% CI, 1.32-1.67) and 76% increased odds of major complications (aOR, 1.76; 95% CI, 1.70-1.83). These associations persisted for the total cohort, among those with mildly low albumin, and for those with creatinine values measured 8 to 30 days preoperatively. CONCLUSIONS: A low preoperative creatinine is common and associated with poor outcomes after nonemergent inpatient surgery. A low creatinine may help identify high-risk patients who may benefit from further evaluation and optimization.

Analysis of Specimen Mammography with Artificial Intelligence to Predict Margin Status.

BACKGROUND: Intraoperative specimen mammography is a valuable tool in breast cancer surgery, providing immediate assessment of margins for a resected tumor. However, the accuracy of specimen mammography in detecting microscopic margin positivity is low. We sought to develop an artificial intelligence model to predict the pathologic margin status of resected breast tumors using specimen mammography. METHODS: A dataset of specimen mammography images matched with pathologic margin status was collected from our institution from 2017 to 2020. The dataset was randomly split into training, validation, and test sets. Specimen mammography models pretrained on radiologic images were developed and compared with models pretrained on nonmedical images. Model performance was assessed using sensitivity, specificity, and area under the receiver operating characteristic curve (AUROC). RESULTS: The dataset included 821 images, and 53% had positive margins. For three out of four model architectures tested, models pretrained on radiologic images outperformed nonmedical models. The highest performing model, InceptionV3, showed sensitivity of 84%, specificity of 42%, and AUROC of 0.71. Model performance was better among patients with invasive cancers, less dense breasts, and non-white race. CONCLUSIONS: This study developed and internally validated artificial intelligence models that predict pathologic margins status for partial mastectomy from specimen mammograms. The models' accuracy compares favorably with published literature on surgeon and radiologist interpretation of specimen mammography. With further development, these models could more precisely guide the extent of resection, potentially improving cosmesis and reducing reoperations.

A Novel Use for Pelvic MRI Scans to Estimate Lean Body Mass and Screen for Sarcopenia in Patients With Rectal Cancer.

BACKGROUND: Sarcopenia, the combination of low lean body mass and decreased muscle strength, is associated with significant morbidity and mortality among patients with colorectal cancer. Standard methods for assessing lean body mass and muscle strength, such as bioelectric impedance analysis and handgrip dynamometry, are rarely obtained clinically. Per National Cancer Center Network recommendations, pelvic MRI is routinely collected for staging and surveillance among patients with rectal cancer. However, there are no data assessing the relationship of pelvic MRI lean body mass measurements at the fifth lumbar vertebrae with bioelectric impedance analysis, handgrip strength, or abdominal CT in patients with rectal cancer. Therefore, we aimed to assess whether pelvic MRI lean body mass correlates with a standard for lean body mass measurement (bioelectric impedance analysis), muscle function (handgrip strength), and an imaging modality frequently used in the literature to identify sarcopenia (abdominal CT at the third lumbar vertebrae). IMPACT OF INNOVATION: Lean body mass measurements from routinely collected pelvic MRI at the fifth lumbar vertebrae accurately and reproducibly estimate lean body mass and modestly correlate with handgrip strength. Rectal cancer pelvic MRI may be repurposed for identifying sarcopenia without increasing inconvenience, ionizing radiation exposure, or expenditure to patients with rectal cancer. TECHNOLOGY, MATERIALS, AND METHODS: Patients with locally advanced rectal cancer with pretreatment bioelectric impedance analysis and handgrip strength measurements within 3 months of their staging pelvic MRI were eligible. Axial skeletal muscle areas were segmented using T1-weighted series pelvic MRI at the fifth lumbar vertebrae and abdominal CT at the third lumbar vertebrae using Slice-O-Matic (Tomovision, Montreal, Canada). Lean body mass (kilograms) was derived from skeletal muscle area with standard equations. Handgrip strength (kilograms) was the maximum of 3 dominant hand attempts in the standing anatomical position. The primary outcome was the agreement between lean body mass measured by pelvic MRI (at the fifth lumbar vertebrae) and bioelectric impedance analysis. Secondary outcomes included the concordance of pelvic MRI lean body mass (at the fifth lumbar vertebrae) with abdominal CT (at the third lumbar vertebrae) and handgrip strength. Additionally, the intra- and interobserver validity, internal consistency, and the mean difference (bias) between lean body mass measurements by pelvic MRI and bioelectric impedance analysis were evaluated. PRELIMINARY RESULTS: Sixteen patients were eligible. The average lean body mass was similar and consistent across 2 observers between bioelectric impedance analysis and pelvic MRI. There was a strong correlation between lean body mass measured on pelvic MRI, bioelectric impedance analysis, and abdominal CT. The reliability of 2 pelvic MRI lean body mass measurements (2 weeks apart by blinded observers) and the correlation of lean body mass between pelvic MRI and bioelectric impedance analysis was strong. Inter- and intraobserver correlation, reliability, and internal consistency were strong for the entire cohort. There was a moderate correlation between pelvic MRI lean body mass and handgrip strength. CONCLUSIONS: Lean body mass measured at the fifth lumbar vertebrae on pelvic MRI is reproducible and correlates strongly with measurements from bioelectric impedance analysis (standard) and abdominal CT at the third lumbar vertebrae and modestly with handgrip strength. These data suggest that MRI lean body mass measurements may be a method to screen patients with rectal cancer for sarcopenia. FUTURE DIRECTIONS: Future studies may evaluate changes in lean body mass on serial pelvic MRI studies among patients with rectal cancer.

Is there an outcome benefit? Patient engagement technology in addition to the electronic medical record patient portal following elective colorectal surgery.

BACKGROUND: Patient engagement technologies (PET) are an area of growing innovation and investment, but whether PET use in the setting of electronic medical record (EMR) supported patient portals are associated with improved outcomes is unknown. Therefore, we assessed PET and EMR activation among patients undergoing elective colorectal surgery on an enhanced recovery pathway. METHODS: We identified adults undergoing elective colorectal surgery between 1/2017 and 7/2021. EMR activations were assessed and patients were considered PET users if they used a proprietary PET application. Multivariable logistic regression was used to identify factors associated with PET use and determine whether the level of engagement (percentage of messages read by the patient) was associated with 30-day outcomes. RESULTS: 484 patients (53.5% PET users, 81.6% with an activated EMR patient portal, 30.8% ≥ 70 years of age) were included. PET users were younger, more likely to have their EMR portal activated and had decreased odds of prolonged length of stay [odds ratio (OR) 0.5, 95% confidence interval (CI) 0.4-0.8]. Among patients ≥ 70 years, PET users had reduced odds of readmissions (OR 0.2, 95% CI 0.1-0.9) compared to PET non-users. The most engaged PET users had decreased morbidity (OR 0.2, 95% CI 0.1-0.8) and readmissions (OR 0.3, 95% CI 0.1-0.8) compared to the least engaged PET users. CONCLUSION: When controlling for EMR activation, patients who use PET, specifically those with higher levels of engagement or aged ≥ 70, have improved outcomes following elective colorectal surgery. Interventions aimed at increasing the adoption of PET among older adults may be warranted.

Epidemiology and healthcare utilization for rectal foreign bodies in United States adults, 2012-2021.

INTRODUCTION: Presentations to the emergency department for rectal foreign bodies are common, but there is little epidemiologic information on this condition. This limits the ability to provide evidence-based education to trainees regarding the populations affected, the types and frequency of foreign bodies, and factors associated with hospitalization. To address this, we analyzed national estimates of emergency department presentations for rectal foreign bodies from 2012 to 2021 in the US. METHODS: We queried the National Electronic Injury Surveillance System for any injury to the 'pubic region' or 'lower trunk' with an accompanying diagnosis of foreign body, puncture, or laceration. Two authors manually reviewed all clinical narratives to identify cases of rectal foreign bodies. National estimates were determined using weighting and strata variables, incidence rates calculated using census data, trends assessed by linear regression, and factors associated with hospitalization identified by multivariable logistic regression. RESULTS: From 885 cases, there were an estimated 38,948 (95% CI, 32,040-45,856) emergency department visits for rectal foreign bodies among individuals ≥15 years from 2012 to 2021. The average age was 43, 77.8% were male, 55.4% of foreign bodies were sexual devices, and 40.8% required hospitalization. The annual incidence of presentations for rectal foreign bodies increased from 1.2 in 2012 to 1.9 per 100,000 persons in 2021 (R2 = 0.84, p < 0.01). Males have a bimodal age distribution peaking in the fifth decade, while females have a right-skewed age distribution peaking in the second decade. Female sex (odds ratio [OR] 0.4; 95% confidence interval [CI], 0.2-0.6) and, compared to sexual devices, balls/marbles (OR 0.2; 95% CI, 0.05-0.6) or drugs/paraphernalia (OR 0.1; 95% CI, 0.05-0.4) are associated with a reduced odds of hospitalization. CONCLUSIONS: Presentations to the emergency department for rectal foreign bodies increased for males and females from 2012 to 2021 in the United States. These epidemiologic estimates for a complex form of anorectal trauma provide preclinical information for emergency medicine, surgery, and radiology trainees.

The lived experiences of young adults grieving an intimate partner or spouse: A phenomenological pilot study.

This pilot study explored the lived experiences of six young adults between the ages of 18-32 years grieving an intimate partner or spouse. Through Moustakas's (1994) steps of transcendental phenomenological analysis, four key themes revealed a traumatic initial period after the death, the importance of helpful vs dismissive community support, a continuation of meaningful activities and ritual to honor the deceased, and significant shifts in participants' life plans and worldviews. These themes suggest that clinicians may consider facilitating identity-restructuring exercises (e.g., journaling) and inclusive community spaces to support this unique population of grievers. Implications for future research are discussed, including the suggestion to create more targeted inclusion criteria to improve the clinical relevance of results in future studies.

Ionic Conductivity of K-ion Glassy Solid Electrolytes of K2S-P2S5-KOTf System.

Ternary glassy electrolytes containing K2S as a glass modifier and P2S5 as a network former are synthesized by introducing a new type of complex and asymmetric salt, potassium triflate (KOTf), to obtain unprecedented K+ ion conductivity at ambient temperature. The glasses are synthesized using a conventional quenching technique at a low temperature. In general, alkali ionic glassy electrolytes of ternary systems, specifically for Li+ and Na+ ion conductivity, have been studied with the addition of halide salts or oxysalts such as M2SO4, M2SiO4, M3PO4 (M = Li or Na), etc. We introduce a distinct and complex salt, potassium triflate (KOTf) with asymmetric anion, to the conventional glass modifier and former to synthesize K+-ion-conducting glassy electrolytes. Two series of glassy electrolytes with a ternary system of (0.9-x)K2S-xP2S5-0.1KOTf (x = 0.15, 0.30, 0.45, 0.60, and 0.75) and z(K2S-2P2S5)-yKOTf (y = 0.05, 0.10, 0.15, 0.20, and 0.25) on a straight line of z(K2S-2P2S5) are studied for their K+ ionic conductivities by using electrochemical impedance spectroscopy (EIS). The composition 0.3K2S-0.6P2S5-0.1KOTf is found to have the highest conductivity among the studied glassy electrolytes at ambient temperature with the value of 1.06 × 10-7 S cm-1, which is the highest of all pure K+-ion-conducting glasses reported to date. Since the glass transition temperatures of the glasses are near 100 °C, as demonstrated by DSC, temperature-dependent conductivities are studied within the range of 25 to 100 °C to determine the activation energies. A Raman spectroscopic study shows the variation in the structural units PS43-, P2S74-, and P2S64- of the network former for different glassy electrolytes. It seems that there is a role of P2S74- and P2S64- in K+-ion conductivity in the glassy electrolytes because the spectroscopic results are compatible with the composition-dependent, room-temperature conductivity trend.

The Impact of Carbohydrate Antigen 19-9 on Survival in Patients with Clinical Stage I and II Pancreatic Cancer.

BACKGROUND: Carbohydrate antigen (CA) 19-9 is a biomarker to monitor treatment effect. A threshold to predict prognostic significance remains undefined. We evaluated the impact of CA19-9 on overall survival (OS) in patients with early-stage pancreatic cancer (PC) utilizing the National Cancer Database (NCDB). METHODS: The NCDB was queried from 2010 to 2014 to identify patients with clinical stage I-II PC. Patients who had undocumented pretreatment CA19-9 were excluded. Patients were stratified into two cohorts: CA19-9 < 98 U/mL and CA19-9 ≥ 98 U/mL, and further categorized into surgery versus no surgery. Twelve- and 24-month OS rates are reported. RESULTS: Overall, 32,382 patients (stage I: 12,173; stage II: 20,209) were included. The majority of stage I (52.1%) and II (60%) patients had CA19-9 ≥ 98 U/mL. Stage I-II patients with CA19-9 < 98 U/mL had improved OS rates (stage I: 67.5%, 42.6%; stage II: 59.8%, 32.8%) compared with stage I and II patients with CA19-9 ≥ 98 U/mL (stage I: 50.7%, 26.9%; stage II: 48.1%, 22%). Among resected stage I patients, CA19-9 <98 U/mL was associated with improved OS (< 98: 80.5%, 56%; ≥ 98: 70.2%, 42.8%), and a similar trend was seen in resected stage II patients (< 98: 77.6%, 49.9%; ≥ 98: 71%, 39.2%). Unresected stage I patients with lower CA19-9 had improved OS (< 98: 42.1%, 17.5; ≥ 98: 29.9%, 10%), with similar findings in unresected stage II patients (< 98: 41.1%, 15.3%; ≥ 98: 33.4%, 10.6%). CONCLUSIONS: Our study demonstrated the prognostic value of CA19-9 in patients with clinical stage I-II PC, with a value < 98 U/mL demonstrating improved survival. Surgery significantly improved survival at 12 and 24 months irrespective of CA19-9.

A review of hepatic epithelioid hemangioendothelioma-Analyzing patient characteristics and treatment strategies.

BACKGROUND: Hepatic epithelioid hemangioendothelioma (HEH) is a rare vascular tumor of unknown etiology and unpredictable natural history. To date, no large-scale studies have been published evaluating this disease due to its rare occurrence. METHODS: The National Cancer Database was reviewed between 2004 and 2016 to identify patients with HEH. Univariate analysis with overall survival (OS) was performed by Cox proportional hazards model. Kaplan-Meier method was used to create OS curves and compared using the log-rank test. RESULTS: We identified 229 patients with HEH. The majority of patients were female (61.1%), white (84.3%), and had a Charlson-Deyo score of 0 (75%). Chemotherapeutic intervention was seen in 26% of the patients while 33% received surgical intervention in the form of wedge/segmental liver resection (n = 27), hepatectomy lobectomy/extended lobectomy (n = 18), and liver transplant (n = 22). Five-year survival in surgical patients was 90.5%, 66.5% and 81%, respectively (p = 0.485). Age greater than 55 years (hazard ratio [HR], 2.78; p < 0.001), Asian ethnicity compared to white (HR, 2.84; p = 0.012), and a higher Charlson-Deyo score (score 1: HR, 2.28; p < 0.001 and score ≥2: HR, 2.76; p = 0.011) were associated with worse OS. CONCLUSION: Treatment for HEH remains variable with only a third of the patients undergoing surgery. International collaboration is necessary to determine the optimal treatment for this rare disease.

Thinking Small: Small Molecules as Potential Synergistic Adjuncts to Checkpoint Inhibition in Melanoma.

Metastatic melanoma remains the deadliest form of skin cancer. Immune checkpoint inhibition (ICI) immunotherapy has defined a new age in melanoma treatment, but responses remain inconsistent and some patients develop treatment resistance. The myriad of newly developed small molecular (SM) inhibitors of specific effector targets now affords a plethora of opportunities to increase therapeutic responses, even in resistant melanoma. In this review, we will discuss the multitude of SM classes currently under investigation, current and prospective clinical combinations of ICI and SM therapies, and their potential for synergism in melanoma eradication based on established mechanisms of immunotherapy resistance.

c-JUN Dimerization Protein 2 (JDP2) Is a Transcriptional Repressor of Follicle-stimulating Hormone ß (FSHß) and Is Required for Preventing Premature Reproductive Senescence in Female Mice.

Follicle-stimulating hormone (FSH) regulates follicular growth and stimulates estrogen synthesis in the ovaries. FSH is a heterodimer consisting of an α subunit, also present in luteinizing hormone, and a unique ß subunit, which is transcriptionally regulated by gonadotropin-releasing hormone 1 (GNRH). Because most FSH is constitutively secreted, tight transcriptional regulation is critical for maintaining FSH levels within a narrow physiological range. Previously, we reported that GNRH induces FSHß (Fshb) transcription via induction of the AP-1 transcription factor, a heterodimer of c-FOS and c-JUN. Herein, we identify c-JUN-dimerization protein 2 (JDP2) as a novel repressor of GNRH-mediated Fshb induction. JDP2 exhibited high basal expression and bound the Fshb promoter at an AP-1-binding site in a complex with c-JUN. GNRH treatment induced c-FOS to replace JDP2 as a c-JUN binding partner, forming transcriptionally active AP-1. Subsequently, rapid c-FOS degradation enabled reformation of the JDP2 complex. In vivo studies revealed that JDP2 null male mice have normal reproductive function, as expected from a negative regulator of the FSH hormone. Female JDP2 null mice, however, exhibited early puberty, observed as early vaginal opening, larger litters, and early reproductive senescence. JDP2 null females had increased levels of circulating FSH and higher expression of the Fshb subunit in the pituitary, resulting in elevated serum estrogen and higher numbers of large ovarian follicles. Disruption of JDP2 function therefore appears to cause early cessation of reproductive function, a condition that has been associated with elevated FSH in women.

Concurrent and lasting effects of emotion regulation on amygdala response in adolescence and young adulthood.

This study used functional MRI (fMRI) to examine a novel aspect of emotion regulation in adolescent development: whether age predicts differences in both the concurrent and lasting effects of emotion regulation on amygdala response. In the first, active regulation, phase of the testing session, fMRI data were collected while 56 healthy individuals (age range: 10.50-22.92 years) reappraised aversive stimuli so as to diminish negative responses to them. After a short delay, the second, re-presentation, phase involved passively viewing the aversive images from the reappraisal task. During active regulation, older individuals showed greater drops in negative affect and inverse rostrolateral prefrontal-amygdala connectivity. During re-presentation, older individuals continued to show lasting reductions in the amygdala response to aversive stimuli they had previously reappraised, an effect mediated by rostrolateral PFC. These data suggest that one source of heightened emotionality in adolescence is a diminished ability to cognitively down-regulate aversive reactions.

Adolescent Self-Consent for the HPV Vaccine and the Effects on Vaccine Rates.

The adolescent development age is the period between 10 and 19 years when a child becomes a young adult and learns to make important health decisions independently. Adolescents consenting to receive a vaccine without parental or legal guardian consent is adolescent self-consent. Adolescent self-consent for the human papillomavirus (HPV) vaccine is a health policy issue that could increase vaccine uptake rates. Adolescent self-consent for the vaccine may increase adolescents' autonomy with their healthcare decisions. Pediatric advanced practice nurses and other healthcare providers should advocate for adolescents and encourage parents to allow adolescents to be more active regarding the HPV vaccine.
