ABSTRACT

OBJECTIVES: To evaluate grayscale US combined with contrast-enhanced ultrasound (CEUS) in the preoperative differentiation between benign and malignant ovarian masses in a pediatric population.

MATERIALS AND METHODS: This retrospective study enrolled patients who underwent grayscale US and CEUS before surgery because of ovarian masses between July 2018 and September 2023, with available histopathologic or follow-up results. Two senior radiologists summarized the grayscale US and CEUS characteristics of all ovarian masses, including percentage of solidity, ascites, vascularity, and enhanced vessel morphology. These characteristics were then independently reviewed by radiologists with different experience to assess interobserver agreement. Diagnostic performance was evaluated using the area under the receiver operating characteristic curve (AUC), while interobserver agreement was evaluated by intraclass correlation coefficient (ICC).

RESULTS: A total of 26 children (median age: 10.1 [7.5, 11.7] years; age range: 0-14 years; benign: 15 patients) were included. The main characteristics of malignant ovarian tumors were abundant blood flow and twisted blood vessels within the mass, enhanced portion of the mass over 50 percent (all p < 0.001). The grayscale US combined with CEUS showed better diagnostic performance than the grayscale US alone (AUC = 0.99 [95% CI: 0.95, 1.00] vs AUC = 0.70 [95% CI: 0.50, 0.90] p < 0.001). A statistically significant AUC before and after CEUS was also shown between two junior radiologists (0.75 vs 0.92 and 0.69 vs 0.86, respectively, both p < 0.05). ICC of CEUS was better than that of grayscale US among radiologists.

CONCLUSION: The combination of grayscale US and CEUS might improve the diagnostic accuracy in differentiating benign and malignant pediatric ovarian masses.

CLINICAL RELEVANCE STATEMENT: Grayscale ultrasound combined with contrast-enhanced ultrasound can improve the diagnostic performance in the preoperative differentiation of benign and malignant ovarian lesions in a pediatric population.

KEY POINTS: Correctly distinguishing benign from malignant ovarian masses in pediatric patients is critical for determining treatments. Grayscale combined with contrast-enhanced ultrasound (CEUS) differentiated benign and malignant pediatric ovarian masses better than grayscale US alone. Junior radiologists’ diagnostic performances could be and were significantly improved with the application of CEUS.

ABSTRACT

Virtual clinical services became the primary treatment modality in a large U.S. HMO psychiatry department during the COVID-19 pandemic. A mixed methods quality improvement project was developed to address psychosis, severe anxiety, and stressors unique to COVID-19 and sheltering in place. The purpose was to determine if a virtual 10-week pilot program combining psychoeducation, skills-based training, experiential exercises using third-wave CBT, and process questions would decrease symptoms and hospitalization rates and improve quality of life. Pre- and postmeasure scores on pandemic-related stress (the PRSF), perceived stress (PSS), and general patient health (PHQ-9) were gathered from five patients in the Department of Psychiatry at Kaiser Permanente in Oakland, California. Qualitative interviews explored patients’ perceptions of program benefits. Mean, median, and range on the pre- and postprogram assessments and paired samples t tests for means were calculated. Quantitative results were not statistically significant: p = 0.32 (Revised PRSF), p = 0.34 (PSS), p = 0.94 (PHQ-9). In interviews, most participants reported a decrease in pandemic-related stress. Half reported a decrease in general perceived stress. Half reported no change. Self-assessment reflected perceptions of benefits from this 10-week program, using words such as useful and important. The virtual program helped relieve pandemic-related stress and improved overall quality of life. The results show promise for expanding the program to other hospitals providing services for this diagnostic population.

ABSTRACT

Lymphocytes are important for protective immunity against infections and cancers, and dysregulation of the immune system may lead to systemic lupus erythematosus (SLE). Metabolic adaptation regulates the fate of lymphocytes. The immune microenvironment is vital role in both SLE and gynecological malignancies. The disruption of the immune microenvironment in SLE is one of the key factors leading to disease occurrence. Overactive autoimmunity indices the body to attack its own tissues, leading to the formation of immune complexes that further trigger tissue damage and inflammation. This imbalance in the immune microenvironment affects the progression of SLE and may also indirectly affect the occurrence of gynecological cancers. For gynecological cancers, immune cells, cytokines, and chemokines in the tumor microenvironment jointly comprise a complex network, and their interactions determine cancer growth, invasion, and metastasis. Mendelian randomization analysis revealed that SLE does not have a statistically significant causal effect on the risk of common cancers of the female reproductive system such as cervical, endometrial, and ovarian cancers in the European population. However, the odds ratio < 1 in the inverse variance weighted results suggest the potential of SLE as a protective factor for endometrial cancer.

ABSTRACT

INTRODUCTION: The impact of chemoimmunotherapy (CIT) on immunoglobulin (Ig) quantities in patients with chronic lymphocytic leukemia (CLL) has not been extensively studied.

METHODS: We analyzed Ig levels in 45 stable patients with indolent CLL (without indication for treatment) and 87 patients with progressive disease before first-line treatment. Fifty-five patients were evaluated again after the treatment with CIT.

RESULTS: We observed significantly lower levels of all Ig classes and subclasses in patients with progressive disease compared to patients with indolent disease. After treatment, median IgA increased from 0.59 g/L to 0.74 g/L (p = 0.0031). In stable patients, lower IgA2 was associated with shorter time to first treatment, although it did not reach statistical significance (p = 0.056). Shorter overall survival was observed in patients with progressive disease and lower IgG2 (p = 0.043). Surprisingly, among the patients with progressive CLL, unmutated IGHV genes were associated with higher levels of IgG, IgG1 and IgM, while TP53 mutation and/or 17p deletion were associated with higher levels of IgA and IgA1.

CONCLUSIONS: CIT may lead to increase in IgA levels. Hypogammaglobulinemia is more common in patients with progressive CLL and unmutated IGHV or TP53 dysfunction.

ABSTRACT

BACKGROUND: Early studies during the COVID-19 pandemic suggested dental occupations were among the highest risk for exposure to SARs-CoV-2 because of multiple factors increasing exposure, including close proximity to unmasked patients and performance of aerosol-generating procedures. However, to date, few studies have investigated COVID-19 deaths in United States dental occupations, and compared COVID-19 deaths among healthcare occupations.

METHODS: We analyzed 2020 mortality data collected by the National Center for Health Statistics’ National Vital Statistics System. Multivariable logistic regression was used to generate odds ratios (ORs) and 95% confidence intervals for COVID-19 as the underlying cause of death in relation to occupation in working-age decedents (≤65 years), after adjusting for age, sex, race/ethnicity, education, and medical conditions associated with severe COVID-19.

RESULTS: Dental occupations did not have significantly higher risk for COVID-19 death when compared to all other occupations combined. Among healthcare occupations with frequent, direct patient- or client interactions, LPNs and LVNs, and speech and language pathologists had significantly elevated adjusted ORs for COVID-19 death when compared to dentists, dental hygienists, or dental assistants. Similarly, nurse practitioners had significantly higher ORs for COVID-19 mortality than dentists or dental hygienists, and approached significance when compared to dental assistants. Conversely, massage therapists and other health diagnosing and treating practitioners had significantly lower adjusted ORs for COVID-19 death compared with dental occupations.

CONCLUSION: Our study highlights potential differences in work-related transmission of SARs-CoV-2 and subsequent COVID-19 deaths in healthcare occupations, and furthers a previously limited understanding of COVID-19 deaths in healthcare occupations in 2020, before COVID-19 vaccine availability. Our results indicate that dental occupations were not among the highest, nor lowest risk, healthcare occupations for COVID-19 deaths in 2020, despite their known risks of direct exposure.

ABSTRACT

Austerity measures have become a contentious topic, shaping the landscape of health care systems around the world. As governments grapple with economic challenges, the impact of austerity on health care has emerged as a critical concern. This study focuses on the consequences of austerity actions adopted by the Zimbabwean government under the Transitional Stabilization Program (TSP) from August 2018 to December 2025. This research examines the impact of austerity measures on Zimbabwe’s health care sector, exploring its connections with health infrastructure and resources, accessibility and affordability of health care, health funding, health care inequalities, and the health care workforce. Using a quantitative approach and data from 970 participants, including the general populace, health care providers, and government officials, significant positive correlations between austerity measures and these health care variables were identified. The findings indicated a noteworthy positive correlation between the independent variable “austerity measures” and five dependent variables: health care accessibility and affordability, health care inequalities, infrastructure and resources, health care funding, and health care workforce. The t-statistics values exceeded the threshold of 1.96, with values of 5.085, 3.120, 6.459, 8.517, and 3.830, respectively. These findings highlight the importance of considering the effects of austerity on health care access, health funding, health care inequalities, health workforce, health infrastructure and resources development. Policymakers should prioritize equitable resource allocation and targeted investments to strengthen the resilience of the health care system during economic challenges. Understanding these associations is crucial for evidence-based policy decisions and fostering a more equitable and resilient health care system in Zimbabwe.

ABSTRACT

BACKGROUND: Person-centred care (PCC) is associated with improved patient well-being and higher levels of satisfaction with care but its impact on individuals living with obesity is not well-established. The main aim of this study was to assess the relationship between PCC and the physical and social well-being of patients living with obesity, as well as their satisfaction with care.

METHODS: This study is based on a cross-sectional, web-based survey administered among a representative panel of Dutch individuals living with obesity. The primary outcomes were physical and social well-being and satisfaction with care. The primary exposure was a rating of overall PCC, encompassing its eight dimensions. In addition, covariates considered in the analyses included sex, age, marital status, education level, BMI, and chronic illness. The data from a total of 590 participants were analysed using descriptive statistics, correlation analyses, and multiple regression analyses.

RESULTS: Among PCC dimensions, participants rated ‘access to care’ the highest (M 4.1, SD 0.6), while ‘coordination of care’ (M 3.5, SD 0.8) was rated lower than all other dimensions. Participants’ overall PCC ratings were positively correlated with their physical (r = 0.255, P<0.001) and social well-being (r = 0.289, P<0.001) and their satisfaction with care (r = 0.788, P<0.001), as were the separate dimension scores. After controlling for sex, age, marital status, education level, BMI, and chronic illness in the regression analyses, participants’ overall PCC ratings were positively related to their physical (β = 0.24, P<0.001) and social well-being (β = 0.26, P<0.001), and satisfaction with care (β = 0.79, P<0.001).

CONCLUSION: PCC holds promise for improved outcomes among patients living with obesity, both in terms of physical and social well-being, as well as satisfaction with care. This is an important finding, particularly when considering the profound physical, social, and psychological consequences associated with obesity. In addition to highlighting the potential benefits of PCC in the healthcare of individuals living with obesity, the findings offer valuable insights into strategies for further refining the provision of PCC to meet the specific needs of these patients.

ABSTRACT

Since November 2023, the absolute number of attendances at emergency departments for pneumonia among children aged 5-14 years in England have been above expected levels for the time of year. This increased signal peaked during March 2024 but then persisted into early summer 2024 despite decreases in prevalence of seasonal respiratory pathogens. Record linkage between emergency department and laboratory databases points to this unusual activity being driven largely by Mycoplasma pneumoniae.

ABSTRACT

BackgroundThe Vibrio genus comprises several bacterial species present in the Baltic Sea region (BSR), which are known to cause human infections.AimTo provide a comprehensive retrospective analysis of Vibrio-induced infections in the BSR from 1994 to 2021, focusing on the ‘big four’ Vibrio species – V. alginolyticus, V. cholerae non-O1/O139, V. parahaemolyticus and V. vulnificus – in eight European countries (Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland and Sweden) bordering the Baltic Sea.MethodsOur analysis includes data on infections, Vibrio species distribution in coastal waters and environmental data received from national health agencies or extracted from scientific literature and online databases. A redundancy analysis was performed to determine the potential impact of several independent variables, such as sea surface temperature, salinity, the number of designated coastal beaches and year, on the Vibrio infection rate.ResultsFor BSR countries conducting surveillance, we observed an exponential increase in total Vibrio infections (n = 1,553) across the region over time. In Sweden and Germany, total numbers of Vibrio spp. and infections caused by V. alginolyticus and V. parahaemolyticus positively correlate with increasing sea surface temperature. Salinity emerged as a critical driver of Vibrio spp. distribution and abundance. Furthermore, our proposed statistical model reveals 12 to 20 unreported cases in Lithuania and Poland, respectively, countries with no surveillance.ConclusionsThere are discrepancies in Vibrio surveillance and monitoring among countries, emphasising the need for comprehensive monitoring programmes of these pathogens to protect human health, particularly in the context of climate change.

ABSTRACT

BackgroundSyphilis in blood donors (BD) has increased in many countries.AimWe aimed to describe trends in syphilis seroposivity in BD in France, to identify risk factors and assess if a non-treponemic test (NTT) could define BD having recovered from syphilis for more than 1 year.MethodsThe analysis covered the period 2007 to 2022 and 45,875,939 donations. Of the 474 BD syphilis-positive in 2022, 429 underwent additional investigations with an NTT. History of syphilis was obtained at the post-donation interview or based on serology results for repeat donors.ResultsUntil 2021, positivity rates remained stable (mean: 1.18/10,000 donations, range: 1.01-1.38). An increased rate was observed in 2022 (1.74/10,000; p = 0.02). Over the whole study period, prevalence was 2.2 times higher in male than in female BD (4.1 times higher in 2022). The proportion of males with an identified risk factor who have sex with men increased from 16.7% in 2007 to 64.9% in 2022. Based on NTT, 79 (18%) of the donors who were seropositive in 2022 were classified as having been infected in the previous year. History of syphilis was available for 30 of them. All had an infection within the previous 3 years. Among seven donors with a syphilis < 12 months before testing, one had an NTT titre ≥ 8, three a titre between 1 and 4, three were negative.ConclusionSyphilis seropositivity increased considerably in BDs in 2022, mostly in males, notably MSM. Available data did not allow appropriate evaluation of the NTT to distinguish recent from past infection.
