RESUMEN

This study investigates the impact of gender discrimination in the labor market on suicidal ideation among Korean women, taking into consideration women's multiple social locations and their discriminatory experiences across various aspects of employment. Analysis using waves 4 to 8 data of the Korean Longitudinal Survey of Women and Family, with response rates ranging from 68.3% to 78.2%, indicates that gender discrimination in hiring, dismissal, promotion, job allocation, training, wage, and sexual harassment is strongly associated with suicidal thoughts among women. This relationship remains significant even after controlling for stress, depression, and other forms of discrimination. Subgroup analysis further highlights that women with lower income levels are particularly susceptible to the adverse effects of gender discrimination. The findings underscore the importance of policy intervention to mitigate labor market discrimination against women as a crucial step in preventing suicides among Korean women.

RESUMEN

BACKGROUND. In 2022, a five-tiered CT algorithm was proposed for predicting whether a small (cT1a) solid renal mass represents clear cell renal cell carcinoma (ccRCC). OBJECTIVE. The purpose of this external validation study was to evaluate the proposed CT algorithm for diagnosis of ccRCC among small solid renal masses. METHODS. This retrospective study included 93 patients (median age, 62 years; 42 women, 51 men) with 97 small solid renal masses that were seen on corticomedullary phase contrast-enhanced CT performed between January 2012 and July 2022 and subsequently underwent surgical resection. Five readers (three attending radiologists, two clinical fellows) independently evaluated masses for the mass-to-cortex corticomedullary attenuation ratio and heterogeneity score; these scores were used to derive the CT score by use of the previously proposed CT algorithm. The CT score's sensitivity, specificity, and PPV for ccRCC were calculated at threshold of 4 or greater, and the NPV for ccRCC was calculated at a threshold of 3 or greater (consistent with thresholds in studies of the MRI-based clear cell likelihood score and the CT algorithm's initial study). The CT score's sensitivity and specificity for papillary RCC were calculated at a threshold of 2 or less. Interreader agreement was assessed using the Gwet agreement coefficient (AC1). RESULTS. Overall, 61 of 97 masses (63%) were malignant and 43 of 97 (44%) were ccRCC. Across readers, CT score had sensitivity ranging from 47% to 95% (pooled sensitivity, 74% [95% CI, 68-80%]), specificity ranging from 19% to 83% (pooled specificity, 59% [95% CI, 52-67%]), PPV ranging from 48% to 76% (pooled PPV, 59% [95% CI, 49-71%]), and NPV ranging from 83% to 100% (pooled NPV, 90% [95% CI, 84-95%]), for ccRCC. A CT score of 2 or less had sensitivity ranging from 44% to 100% and specificity ranging from 77% to 98% for papillary RCC (representing nine of 97 masses). Interreader agreement was substantial for attenuation score (AC1 = 0.70), poor for heterogeneity score (AC1 = 0.17), fair for five-tiered CT score (AC1 = 0.32), and fair for dichotomous CT score at a threshold of 4 or greater (AC1 = 0.24 [95% CI, 0.14-0.33]). CONCLUSION. The five-tiered CT algorithm for evaluation of small solid renal masses was tested in an external sample and showed high NPV for ccRCC. CLINICAL IMPACT. The CT algorithm may be used for risk stratification and patient selection for active surveillance by identifying patients unlikely to have ccRCC.

RESUMEN

The purpose of this report is to investigate the clinical importance of increased or decreased gallbladder ejection fraction (GBEF) and ultrasound findings for biliary dyskinesia by evaluating postsurgical symptom relief and surgical pathology. Single institution electronic medical record review was prepared for patients who underwent hepatobiliary iminodiacetic acid (HIDA) scan with GBEF and cholecystectomy between January 2013 and March 2020. Relevant data included patient demographics, ultrasound results, surgical pathology, HIDA with GBEF results, and postoperative symptom relief at the time of follow-up. Student's t-test was also utilized for additional statistical analysis. A total of 67 patients underwent cholecystectomy within a 1-month period of time after HIDA with GBEF. Of these patients, 97% had findings consistent with chronic cholecystitis and 3% of the patients demonstrated both acute and chronic cholecystitis surgical pathology. Fifty-seven percent of the patients demonstrated a GBEF <38%, 30% had a GBEF >80%, and 13% had a GBEF 38%-80% with a postoperative symptom resolution around 82%, 77%, and 100%, respectively. GBEF alone may not be determinative regarding gallbladder pathology or postoperative symptom relief in patients that present with typical symptoms. Regarding dyskinetic gallbladders, elevated and decreased GBEF groups were not significantly different in terms of surgical pathology or symptom relief. These patients may benefit from being treated as a single group rather than as separate entities. Elevated and decreased GBEF groups demonstrated mostly normal ultrasound results that raised concern for the utility of ultrasound as a rule out test for gallbladder inflammation.

RESUMEN

RATIONALE AND OBJECTIVES: The impact of emergent whole spine magnetic resonance imaging (WS-MRI) on patient management has not been extensively studied to date. Here, we explore indications, results, and outcomes associated with WS-MRI performed through the emergency departments (EDs) of 2 large tertiary care, academic medical centers in the Northeastern United States. We hypothesize that given a relatively low barrier to entry, coupled with lack of appropriateness guidelines, a sizeable proportion of WS-MRI studies performed emergently do not result in spine findings necessitating inpatient admission for immediate treatment. MATERIALS AND METHODS: We retrospectively studied 335 adult patients (≥18 years) who underwent WS-MRI through the ED between 2016 and 2019. The demographic data collected included, age, sex, chief complaint, history of spine disease, and date and type of last spine imaging prior to ED presentation. Data compiled from the time of ED visit included WS-MRI result and patient disposition, including reason for hospital admission, by which patients were categorized into groups to allow for ease of comparisons. Hypergeometric tests were used to determine statistically significant associations between random discrete variables. RESULTS: Trauma was the most frequent chief complaint, comprising 35% (n = 117) of all presentations, followed by pain (25%, n = 84), motor deficit (16%, n = 55), sensory disturbance (12%, n = 41), bowel, and/or bladder dysfunction (9%, n = 30), and subjective or objective fevers with suspicion for spine infection (2%, n = 8). The largest proportion of WS-MRI studies revealed degenerative disc disease (DDD) as the principal result (41%, n = 139). 52% of all patients were either discharged directly from the ED (41%) or admitted for a non-spine issue after WS-MRI (11%); of these numbers, 61% underwent WS-MRI and no other imaging study in the ED. In patients who presented with a chief complaint of pain, DDD was often the principal WS-MRI finding (54%), albeit this association was not statistically significant. DDD, nonetheless, was positively associated with a discharge from the ED (P <0.001). Trauma was positively associated with fracture or ligamentous/soft tissue injury (P <0.001) on WS-MRI and hospital admission for a spine issue (P <0.01). CONCLUSION: That just under half of patients in our study were admitted for spine-related pathology suggests that WS-MRI is valuable in the emergent setting. At the same time, however, that over half of patients were not subsequently admitted for a spine-related issue points to the possibility of further refining which patients would benefit most from WS-MRI. WS-MRI may be less helpful in patients presenting with pain, though may be higher-yield in those with trauma, motor deficits, and bowel/bladder complaints. Although MRI is highly sensitive in ruling out emergent central nervous system pathology, given the resource-intensive nature of the test, it is prudent to carefully select which patients should undergo emergent WS-MRI, especially in instances when more cost-effective, alternative diagnostic approaches, including detailed neurological exam, computed tomography, or localized/targeted MRI, are possible.

RESUMEN

Cat scratch disease is an infection caused by Bartonella Henselae with characteristic presentation of lymphadenopathy. Despite self-limited nature of the disease in most cases, it accounts for many lymph node biopsies performed since its imaging features can mimic lymphoma in appearance, thus requiring additional invasive procedures. Lack of restricted diffusion may be helpful in distinguishing imaging feature of reactive lymph nodes with caseating necrosis seen in cat scratch disease from lymphoma or abscess. We present a case of 12-year-old female, who presented with an arm swelling, MRI of which demonstrated absence of restricted diffusion in the subcutaneous enlarged lymph nodes. She then underwent excisional biopsy with final diagnosis of reactive lymph node and cat scratch disease based on biopsy results and immunoglobulin titer.

RESUMEN

Non-immune hydrops fetalis (NIHF) has a high mortality rate [1]. Many etiologies of NIHF have been identified, including cardiovascular abnormalities, severe anemia, and genetic defects. In patients with cardiovascular etiology, structural malformations lead to fluid accumulation resulting in increased intravascular hydrostatic pressure. We report a fatal case of NIHF in a 31 week gestational age, Caucasian neonate with heart remodeling associated with a stenotic vasculopathy of the right pulmonary artery. The artery revealed partial occlusion with vascular wall abnormalities, including disarrayed smooth muscle fibers, hyperplasia within the tunica media, and myxoid change within the media and intima. Identical vasculopathy was also identified within a mesenteric artery, and this contributed to hemorrhage and early ischemic necrosis of the small intestine, discovered on postmortem examination.

RESUMEN

BACKGROUND: Despite advances in endovascular surgery, lower extremity arterial bypass remains the gold standard treatment for severe, symptomatic peripheral arterial disease (PAD). Patients who are transferred to other hospitals have generally complex medical problems compared to those patients who are directly admitted from home. The purpose of this study is to identify factors associated with an interfacility transfer in patients with PAD and compare the postoperative outcomes of these patients to those who are directly admitted to the hospital. METHODS: The 2013 lower extremity revascularization-targeted American College of Surgeons (ACS-National Surgical Quality Improvement Program [NSQIP]) database and generalized 2013 general and vascular surgery ACS-NSQIP Participant Use File were used for this study. Patient, diagnosis, and procedure characteristics of patients undergoing lower extremity bypass surgery were assessed. Multivariate logistic regression analysis was used to determine independent risk factors for transfer to another hospital. RESULTS: A total of 2,646 patients (65% male, 35% female) were identified in the NSQIP database that underwent lower extremity open revascularization during the year 2013. A total of 287 patients (11%) were transferred from other institutions: acute care hospital inpatient (4%), nursing home/chronic care/intermediate care (3%), outside emergency department (3%), and other (1%). Factors associated with increased risk of interfacility transfer included need for emergency surgery (odds ratio [OR]: 5.51, P < 0.05), infected wounds (OR: 2.77, P < 0.05), and age >85 years (OR: 2.24, P < 0.05). Postoperative outcome associated with transfer was mortality <30 days postop (OR: 1.96) and length of stay >30 days (OR: 2.04; P < 0.05). CONCLUSIONS: Multiple factors affect an interfacility transfer of patients including advanced age, need for emergency procedure, contaminated wounds. Patients who are transferred from another institution for a lower extremity bypass surgery are at a substantially higher risk for postoperative morbidity and mortality.
