HMGB1 mediates microbiome-immune axis dysregulation underlying reduced neutralization capacity in obesity-related post-acute sequelae of SARS-CoV-2.

While obesity is a risk factor for post-acute sequelae of SARS-CoV-2 infection (PASC, "long-COVID"), the mechanism(s) underlying this phenomenon remains poorly understood. To address this gap in knowledge, we performed a 6-week longitudinal study to examine immune activity and gut microbiome dysbiosis in post-acute stage patients recovering from SARS-CoV-2 infection. Self-reported symptom frequencies and blood samples were collected weekly, with plasma assessed by ELISA and Luminex for multiple biomarkers and immune cell profiling. DNA from stool samples were collected at the early stage of recovery for baseline assessments of gut microbial composition and diversity using 16S-based metagenomic sequencing. Multiple regression analyses revealed obesity-related PASC linked to a sustained proinflammatory immune profile and reduced adaptive immunity, corresponding with reduced gut microbial diversity. In particular, enhanced signaling of the high mobility group box 1 (HMGB1) protein was found to associate with this dysregulation, with its upregulated levels in plasma associated with significantly impaired viral neutralization that was exacerbated with obesity. These findings implicate HMGB1 as a candidate biomarker of PASC, with potential applications for risk assessment and targeted therapies.

Knowledge on cause, clinical manifestation and treatment for fibromyalgia among medical doctors: A worldwide survey.

OBJECTIVES: Hench introduced the fibromyalgia syndrome almost 50 years ago. In the meantime, the prevalence has increased, the clinical criteria have changed and the way we explain (chronic) pain has altered. DESIGN: In the current study, we conducted a worldwide survey in which we investigate whether medical doctors are familiar with the American College of Rheumatology (ACR) criteria for fibromyalgia and, if so, whether these medical doctors adhere to the clinical guidelines following evidence-based treatments. RESULTS: In total, 286 medical doctors from 43 countries spread over 6 continents filled out the survey. In most of the countries, the diagnosis fibromyalgia was used. Only 10% adhere to the ACR criteria, widespread pain (44%), unrefreshed sleep (24%), fatigue (20%) and cognitive problems (8%) were most used diagnostic criteria. Of the respondents, 94 (32%) mentioned that the cause is unknown or idiopathic, but also a wide variety of other causes was mentioned. More than 70 different treatment options were provided, of which 24% of the responses were classified as according to the clinical guidelines. From this study, we conclude that many medical doctors do not follow the ACR criteria; the majority has an inappropriate knowledge of causes for fibromyalgia and that a minority of treatment advice adhere to the guidelines.

Reappraising personal values in cancer: Meaning-in-life adaptation, meaningfulness, and quality of life.

OBJECTIVE: This study explores the reappraisal of personal values among people with cancer post-diagnosis and its connections to meaningfulness, encompassing personal meaning and sense of meaning, and various dimensions of quality of life. METHODS: A total of 144 patients with diverse cancer types and a control group comprising 158 healthy adults with similar demographic characteristics completed the Valued Living Questionnaire-Perceived Change, the Personal Meaning Profile-Brief, the Portrait Values Questionnaire, and the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being. RESULTS: Cancer patients displayed a substantial values reappraisal compared to healthy adults. They reported an increased significance of social areas and self-transcendental values, including close relationships (family, partner, and friends), spirituality, citizenship, and universalism, as well as an increased importance of self-care and self in general. Conversely, cancer patients assigned less importance to work and self-enhancement values such as stimulation, power, and achievement. Cluster analysis revealed that patients who reappraised their values exhibited higher meaningfulness and better indicators of quality of life, including spiritual and physical well-being, compared to patients who did not modify their value system. CONCLUSIONS: These findings underscore the importance of assessing and promoting meaning-in-life adaptability among people with cancer, with potential applications in meaning-centered therapies and interventions aimed at enhancing psychological flexibility.

The Mauli Ola Study: A Unique Academic-Community Partnership With MA'O Organic Farms to Understand and Address Health Inequities Among Native Hawaiians and Other Pacific Islanders in Hawai'i.

Indigenous peoples, including Native Hawaiians and Pacific Islanders (NHPIs), experience significant cardiometabolic health disparities arising in large part from rapid changes to their diets and food systems. Innovative food sovereignty initiatives led by NHPIs are needed to address these disparities. This article describes a community-based participatory research study that incorporates social and biological measures to examine the impact of an Indigenous-led land-based food sovereignty youth leadership program on health disparities among NHPI youth in Hawai'i. Grounded in the Indigenous knowledge that holistic health and wellbeing of people is inseparable from that of the environment and to counter rampant food insecurity in their community of Wai'anae, O'ahu, MA'O Organic Farms developed a Youth Leadership Training (YLT) program that offers education, nutrition, physical activity, and access to health care. The program also engages YLT interns and their social networks in health education and research in the ongoing Mauli Ola study. Preliminary data from this study affirm the need to address the disproportionately high rates of obesity, type 2 diabetes mellitus (T2D), and poor mental health conditions among young NHPIs in the Wai'anae community, and how the YLT program may provide an effective approach to address this need. Our unique academic-community partnership underscores the importance of social and biomedical research to understand health disparities in the NHPI population, which present novel avenues to enable disease prevention. The outcomes of the Mauli Ola study may serve as a valuable model for health disparities research while leveraging ongoing social programs that support Indigenous food sovereignty.

NeoStarling: An Efficient and Scalable Collaborative Blockchain-Enabled Obstacle Mapping Solution for Vehicular Environments.

The Vehicular Self-Organizing Network (VANET) is a burgeoning research topic within Intelligent Transportation Systems, holding promise in enhancing safety and convenience for drivers. In general, VANETs require large amounts of data to be shared among vehicles within the network. But then two challenges arise. First, data security, privacy, and reliability need to be ensured. Second, data management and security solutions must be very scalable, because current and future transportation systems are very dense. However, existing Vehicle-to-Vehicle solutions fall short of guaranteeing the veracity of crucial traffic and vehicle safety data and identifying and excluding malicious vehicles. The introduction of blockchain technology in VANETs seeks to address these issues. But blockchain-enabled solutions, such as the Starling system, are too computationally heavy to be scalable enough. Our proposed NeoStarling system focuses on proving a scalable and efficient secure and reliable obstacle mapping using blockchain. An opportunistic mutual authentication protocol, based on hash functions, is only triggered when vehicles travel a certain distance. Lightweight cryptography and an optimized message exchange enable an improved scalability. The evaluation results show that our collaborative approach reduces the frequency of authentications and increases system efficiency by 35%. In addition, scalability is improved by 50% compared to previous mechanisms.

Sequencing the SARS-CoV-2 Genome from Stool Samples of Post-acute Cases Implicates a Novel Mutation Associated with Reduced Antibody Neutralization.

Whole-genome SARS-CoV-2 sequencing tools are crucial for tracking the COVID-19 pandemic. However, current techniques require sampling of actively infectious patients following COVID-19 testing to recover enough SARS-CoV-2 RNA from the nasopharyngeal passage, which rapidly clears during the first few weeks of infection. A prospective assessment of the viral genome sourced from recovered non-infectious patients would greatly facilitate epidemiological tracking. Thus, we developed a protocol to isolate and sequence the genome of SARS-CoV-2 from stool samples of post-acute SARS-CoV-2 patients, at timepoints ranging from 10-120 days after onset of symptoms. Stool samples were collected from patients at varying timepoints post-convalescence, and viral DNA was isolated and sequenced using the QIAamp Viral RNA Mini Kit (Qiagen Inc.) and Ion Ampliseq™ Library Kit Plus (Life Technologies Corporation). Capacity of neutralizing antibodies in patient plasma was tested using a Luminex panel (Coronavirus Ig Total Human 11-Plex ProcartaPlex™ Panel, ThermoFisher). Of 64 samples obtained from post-acute patients, 21 (32.8%) yielded sufficient material for whole-genome sequencing. This allowed us to identify widely divergent phylogenetic relativity of the SARS-CoV-2 genome from post-acute patients living in the same households and infected around the same time. Additionally, we observed that individuals who recovered from infection expressed varying degrees of antibodies against SARS-CoV-2 structural proteins that corresponded to distinct variants. Interestingly, we identified a novel point mutation in the viral genome where infected patients expressed antibodies with a significantly reduced capacity to neutralize the virus in vitro relative to that of those infected with the wild-type strain. Altogether, we demonstrate a protocol to successfully sequence the SARS-CoV-2 genome from stool samples from patients up to 4 months post-infection, which can be applied to studies that assess the relationship between variants and immune response post-hoc and safe monitoring of the SARS-CoV-2 genome during the pandemic.

Long COVID and Unemployment in Hawaii.

The state of Hawaii has seen 390,000 COVID-19 cases and nearly 1900 deaths since the start of the pandemic. Although the negative impact of the pandemic on employment has been widely documented, this paper demonstrates that those who were infected and suffer from lingering symptoms (i.e., long COVID) had different employment outcomes than those who did not experience such symptoms. Using data from our longitudinal cohort in the state of Hawaii, we found that those who reported long COVID in May 2022 were 6.43% more likely to be unemployed at the time of the May survey and 7.07% more likely in November 2022. In addition, we showed that vaccination is associated with higher rates of employment; each additional vaccine an individual received by May decreased the likelihood of unemployment by 6.9% in May and 3.9% in November. Further, individuals who reported more severe symptoms of long COVID were 6.36% less likely to be employed in May and 5.75% less likely to be employed in November. Our results suggest that vaccination policies and policies aimed at preventing contraction and accommodating individuals with long COVID may be effective measures for mitigating the adverse effects of the pandemic on employment.

Examining the immunoepigenetic-gut microbiome axis in the context of self-esteem among Native Hawaiians and other Pacific Islanders.

Introduction: Native Hawaiian and other Pacific Islander (NHPI) populations experience higher rates of immunometabolic diseases compared to other racial-ethnic groups in Hawaii. As annual NHPI mortality rates for suicide and type 2 diabetes mellitus (T2DM) exceed those of the state as a whole, understanding the social and biological mechanisms underlying these disparities are urgently needed to enable preventive strategies. Methods: A community-based approach was used to investigate the immunoepigenetic-gut microbiome axis in an NHPI-enriched cohort of Oahu residents (N = 68). Self-esteem (SE) data was collected using a modified Rosenberg self-esteem (SE) assessment as a proxy measure for mental wellbeing in consideration for cultural competency. T2DM status was evaluated using point-of-care A1c (%) tests. Stool samples were collected for 16s-based metagenomic sequencing analyses. Plasma from blood samples were isolated by density-gradient centrifugation. Peripheral blood mononuclear cells (PBMCs) were collected from the same samples and enriched for monocytes using negative selection techniques. Flow-cytometry was used for immunoprofiling assays. Monocyte DNA was extracted for Illumina EPIC array-based methylation analysis. Results: Compared to individuals with normal SE (NSE), those with low SE (LSE) exhibited significantly higher plasma concentrations (pg/ml) of proinflammatory cytokines IL-8 (p = 0.051) and TNF-α (p = 0.011). Metagenomic analysis revealed that the relative abundance (%) of specific gut bacteria significantly differed between SE groups - some of which directly correlated with SE scores. Gene ontology analysis revealed that 104 significantly differentially methylated loci (DML) between SE groups were preferentially located at genes involved in immunometabolic processes. Horvath clock analyses indicated epigenetic age (Epi-Age) deceleration in individuals with LSE and acceleration in individuals with NSE (p = 0.042), yet was not reproduced by other clocks. Discussion: These data reveal novel differences in the immunoepigenetic-gut microbiome axis with respect to SE, warranting further investigation into its relationship to brain activity and mental health in NHPI. Unexpected results from Epi-Age analyses warrant further investigation into the relationship between biological age and disparate health outcomes among the NHPI population. The modifiable component of epigenetic processes and the gut microbiome makes this axis an attractive target for potential therapeutics, biomarker discovery, and novel prevention strategies.

Vaccine-Associated Shifts in SARS-CoV-2 Infectivity Among the Native Hawaiian and Other Pacific Islander Population in Hawaii.

Native Hawaiians and other Pacific Islanders (NHPIs) across the country have experienced significant disparities because of the COVID-19 pandemic. The Pacific Alliance Against COVID-19 used a community-based participatory approach involving academic and community partners to expand sustainable COVID-19 testing capacity and mitigate the severe consequences among NHPI communities in Hawaii. We describe the approach of this one-year study, some of the results, and how the data are being used to inform next steps for the communities. Clinical Trials.gov identifier: NCT04766333. (Am J Public Health. 2022;112(S9):S896-S899. https://doi.org/10.2105/AJPH.2022.306973).

Dynamics of Trust and Consumption of COVID-19 Information Implicate a Mechanism for COVID-19 Vaccine and Booster Uptake.

Vaccine hesitancy remains a significant barrier to achieving herd immunity and preventing the further spread of COVID-19. Understanding contributors to vaccine hesitancy and how they change over time may improve COVID-19 mitigation strategies and public health policies. To date, no mechanism explains how trust in and consumption of different sources of information affect vaccine uptake. A total of 1594 adults enrolled in our COVID-19 testing program completed standardized surveys on demographics, vaccination status, use, reliance, and trust in sources of COVID-19 information, from September to October 2021, during the COVID-19 Delta wave. Of those, 802 individuals (50.3%) completed a follow-up survey, from January to February 2022, during the Omicron-wave. Regression analyses were performed to understand contributors to vaccine and booster uptake over time. Individuals vaccinated within two months of eligibility (early vaccinees) tended to have more years of schooling, with greater trust in and consumption of official sources of COVID-19 information, compared to those who waited 3-6 months (late vaccinees), or those who remained unvaccinated at 6 months post-eligibility (non-vaccinees). Most (70.1%) early vaccinees took the booster shot, compared to only 30.5% of late vaccinees, with the latter group gaining trust and consumption of official information after four months. These data provide the foundation for a mechanism based on the level of trust in and consumption of official information sources, where those who increased their level of trust in and consumption of official information sources were more likely to receive a booster. This study shows that social factors, including education and individual-level degree of trust in (and consumption of) sources of COVID-19 information, interact and change over time to be associated with vaccine and booster uptakes. These results are critical for the development of effective public health policies and offer insights into hesitancy over the course of the COVID-19 vaccine and booster rollout.

Opposing Role of Trust as a Modifier of COVID-19 Vaccine Uptake in an Indigenous Population.

Native Hawaiians and other Pacific Islanders (NHPIs) were disproportionately impacted by COVID-19 and remain significantly under-vaccinated against SARS-CoV-2. To understand vaccine hesitancy, we surveyed 1124 adults residing in a region with one of the lowest vaccination rates in Hawaii during our COVID-19 testing program. Probit regression analysis revealed that race/ethnicity was not directly associated with the probability of vaccine uptake. Instead, a higher degree of trust in official sources of COVID-19 information increased the probability of vaccination by 20.68%, whereas a higher trust in unofficial sources decreased the probability of vaccination by 12.49% per unit of trust. These results revealed a dual and opposing role of trust on vaccine uptake. Interestingly, NHPIs were the only racial/ethnic group to exhibit a significant positive association between trust in and consumption of unofficial sources of COVID-19 information, which explained the vaccine hesitancy observed in this indigenous population. These results offer novel insight relevant to COVID-19 mitigation efforts in minority populations.

Ozonation of 14C-labeled micropollutants - mineralization of labeled moieties and adsorption of transformation products to activated carbon.

Ozonation transformation products (OTPs) are largely unknown compounds that are formed during the ozonation of micropollutants, and it is uncertain to which extent these compounds can be removed by subsequent adsorption to activated carbon. Thus, 14C-labeled micropollutants were ozonated to generate 14C-labeled OTPs, for which the adsorption of the sum of all 14C-labeled OTPs to activated carbon could be determined, based on the adsorption of the labeled carbon. Further, 14CO2 traps were used to examine the mineralization of 14C-labeled moieties during ozonation. 14CO2-formation revealed a partial mineralization of the 14C-labeled moieties in all compounds except for propyl-labeled bisphenol A and O-methyl-labeled naproxen. A similar degree of mineralization was noted for different compounds labeled at the same moiety, including the carboxylic carbon in diclofenac and ibuprofen (∼40% at 1 g O3/g DOC) and the aniline ring in sulfamethoxazole and sulfadiazine (∼30% at 1 g O3/g DOC). Aromatic ring cleavage was also confirmed for bisphenol A, sulfamethoxazole, and sulfadiazine through the formation of 14CO2. The adsorption experiments demonstrated increased adsorption of micropollutants to powdered activated carbon after ozonation, which was connected to a decreased adsorption of dissolved organic matter (DOM). Conversely, the OTPs showed a substantial and successive decline in adsorption at increased ozone doses for all compounds, likely due to decreased hydrophobicity and aromaticity of the OTPs. These findings indicate that adsorption to activated carbon alone is not a viable removal method for a wide range of ozonation transformation products.

Microbial bromate reduction following ozonation of bromide-rich wastewater in coastal areas.

Ozonation of wastewater can reduce the release of organic micropollutants, but may result in the formation of undesirable by-products, such as bromate from bromide. Bromide is one of the most abundant ions in seawater, the primary precursor of bromate during ozonation, and the end product in microbial bromate reduction. Investigations were carried out to compare the concentration of bromide in wastewater in coastal and non-coastal catchment areas, to monitor bromate formation during ozonation, and to assess the potential for subsequent bromate reduction with denitrifying carriers. Higher bromide concentrations were systematically observed in wastewater from coastal catchment areas (0.2-2 mg Br-/L) than in wastewater from non-coastal areas (0.06-0.2 mg Br-/L), resulting in elevated formation of bromate during ozonation. Subsequent investigations of bromate reduction in contact with denitrifying carriers from two full-scale moving bed biofilm reactors (MBBRs) showed that 80 % of the bromate formed during ozonation could be reduced to bromide in 60 min with first-order rate constants of 0.3-0.8 L/(gbiomass·h). Flow-through experiments with denitrifying carriers also showed that combined reduction of bromate and nitrate could be achieved below a concentration of 2 mg NOx--N/L. These findings indicate that bromide-rich wastewater is more likely to be of concern when using ozonation in coastal than in non-coastal areas, and that bromate and nitrate reduction can be combined in a single biofilm reactor.

The Effects of COVID-19 Vaccine Mandates in Hawaii.

Having been affected by the highest increase in COVID-19 cases since the start of the pandemic, Honolulu and Maui counties in Hawaii implemented vaccine passport mandates for select industries in September 2021. However, the degree to which such mandates impacted COVID-19 mitigation efforts and economics remains poorly understood. Herein, we describe the effects of these mandates on changes in three areas using difference-in-difference regression models: (1) business foot traffic; (2) number of COVID-19 cases per 100,000 individuals, and (3) COVID-19 vaccination rates across counties affected or unaffected by the mandates. We observed that although businesses affected by mandates experienced a 6.7% decrease in foot traffic over the 14 weeks after the mandates were implemented, the number of COVID-19 cases decreased by 19.0%. Notably, the vaccination rate increased by 1.41% in counties that implemented mandates. In addition, towards the end of the studied period, the level of foot traffic at impacted businesses converged towards the level of that of non-impacted businesses. As such, the trade-off in temporary losses at businesses was met with significant gains in public health and safety.

Practices and Perceptions of Local Health Officers/Commissioners Regarding Tobacco 21 Policy Advocacy.

Progress has been made in reducing adolescent cigarette smoking. However, the popularity of vaping products has increased concerns regarding tobacco use. One policy recently passed at the national level is Tobacco 21 (T21), which aims to reduce adolescent's access to tobacco products. Since local health officers/commissioners play a crucial role in the development of policies that protect their respective communities from the harms of tobacco, it is important to characterize their views on the T21 legislation and advocacy activities among them. This was a cross-sectional pilot study of three Midwestern states taken prior to a number of key tobacco-related events in 2019. Results show almost 70% of respondents had high interest in influencing public policy, more than 80% thought the public policy makers' actions regarding T21 were highly important to the health and well-being of the public, and 89% had in some capacity acted to support a T21 initiative. Involvement with legislative efforts was not high, despite evidence showing high popularity of the measure among the public. The top perceived benefits included a decrease in tobacco use among adolescents, improvements to community or state health, and delay in tobacco use initiation. Top barriers listed were issues with enforcement, lack of money or resources, competing health priorities, and policy makers' attitudes and values. Respondents overall had significantly lower confidence in performing activities at the state versus local level. Findings suggest there may be a need for more advocacy training on effective advocacy strategies in changing health policy.

Gut microbial indicators of metabolic health underlie age-related differences in obesity and diabetes risk among Native Hawaiians and Pacific Islanders.

Native Hawaiians and Pacific Islanders (NHPIs) suffer from higher prevalence of and mortality to type 2 diabetes mellitus (T2DM) than any other major race/ethnic group in Hawaii. Health inequities in this indigenous population was further exacerbated by the SARS-CoV-2 pandemic. T2DM progression and medical complications exacerbated by COVID-19 are partially regulated by the gut microbiome. However, there is limited understanding of the role of gut bacteria in the context of inflammation-related diseases of health disparities including T2DM and obesity. To address these gaps, we used a community-based research approach from a cohort enriched with NHPI residents on the island of Oahu, Hawaii (N=138). Gut microbiome profiling was achieved via 16s rDNA metagenomic sequencing analysis from stool DNA. Gut bacterial capacity for butyrate-kinase (BUK)-mediated fiber metabolism was assessed using quantitative PCR to measure the abundance of BUK DNA and RNA relative to total bacterial load per stool sample. In our cohort, age positively correlated with hemoglobin A1c (%; R=0.39; P<0.001) and body mass index (BMI; R=0.28; P<0.001). The relative abundance of major gut bacterial phyla significantly varied across age groups, including Bacteroidetes (P<0.001), Actinobacteria (P=0.007), and Proteobacteria (P=0.008). A1c was negatively correlated with the relative levels of BUK DNA copy number (R=-0.17; P=0.071) and gene expression (R=-0.33; P=0.003). Interestingly, we identified specific genera of gut bacteria potentially mediating the effects of diet on metabolic health in this cohort. Additionally, α-diversity among gut bacterial genera significantly varied across T2DM and BMI categories. Together, these results provide insight into age-related differences in gut bacteria that may influence T2DM and obesity in NHPIs. Furthermore, we observed overlapping patterns between gut bacteria and T2DM risk factors, indicating more nuanced, interdependent interactions among these factors as partial determinants of health outcomes. This study adds to the paucity of NHPI-specific data to further elucidate the biological characteristics associated with pre-existing health inequities in this racial/ethnic group that is significantly underrepresented in biomedical research.

Tratamiento laparoscópico de una paciente con un leiomioma uterino gigante cavitado, con cambio degenerativo mucomixoide / Laparoscopic treatment of a patient with a cavitated giant uterine leiomyoma with mucomyxoid degenerative change

Resumen INTRODUCCIÓN: Un leiomioma con cambios degenerativos poco frecuentes es un desafío diagnóstico difícil de diferenciar de sus homólogos malignos, si se pretende fundamentarlo solo en lo advertido en las imágenes. CASO CLÍNICO: Paciente de 40 años de edad, enviada al servicio de Cirugía de mínima invasión en marzo del 2021 debido al aumento del perímetro abdominal, disminución del apetito y disnea de medianos esfuerzos. El ultrasonido abdomino-pélvico reportó que el útero estaba aumentado de tamaño, con miomas intramurales de medianos elementos. El endometrio heterogéneo. El ovario derecho tenía un quiste complejo, gigante, de 276 mm x 250 mm x 276 mm, con volumen de 10 000 cc. Además, esplenomegalia, hidronefrosis derecha y litiasis renal izquierda. Los marcadores tumorales se reportaron normales. En la cirugía por laparoscopia se observó un tumor que ocupaba toda la cavidad abdominal de 40 x 30 cm, adherido a la pared posterior del útero, con ambos ovarios sin alteraciones, sin líquido libre; se procedió a la histerectomía total. CONCLUSIONES: Los cambios degenerativos en los leiomiomas uterinos pueden distorsionar la estructura habitual del tumor y reflejarla en imágenes típicas de una tumoración quística de ovario; en el estudio inicial esto representa un desafío para el cirujano y debe considerarse parte del diagnóstico diferencial de las masas anexiales. En la paciente del caso, con cirugía de mínima invasión, se consiguió la resección completa de la pieza, a pesar del tamaño aumentado, con menores riesgos de complicaciones en la herida y menos dolor posoperatorio; las incisiones son pequeñas y con desenlaces estéticos favorables y menos días de estancia intrahospitalaria.

Abstract INTRODUCTION: A leiomyoma with rare degenerative changes is a diagnostic challenge difficult to differentiate from its malignant counterparts, if it is intended to be based only on imaging findings. CLINICAL CASE: 40-year-old female patient referred to the Minimally Invasive Surgery service in March 2021 due to increased abdominal perimeter, decreased appetite and dyspnea on medium exertion. Abdomino-pelvic ultrasound reported that the uterus was enlarged, with medium-element intramural fibroids. The endometrium was heterogeneous. The right ovary had a complex, giant cyst, 276 mm x 250 mm x 276 mm, with a volume of 10,000 cc. In addition, splenomegaly, right hydronephrosis and left renal lithiasis. Tumor markers were reported normal. Laparoscopic surgery showed a tumor occupying the entire abdominal cavity measuring 40 x 30 cm and attached to the posterior wall of the uterus, with both ovaries unaltered, with no free fluid; total hysterectomy was performed. CONCLUSIONS: Degenerative changes in uterine leiomyomas can distort the usual tumor structure and reflect it in images typical of an ovarian cystic tumor; in the initial study this represents a challenge for the surgeon and should be considered part of the differential diagnosis of adnexal masses. In the case patient, with minimally invasive surgery, complete resection of the specimen was achieved, despite the increased size, with less risk of wound complications and less postoperative pain; the incisions are small and with favorable esthetic outcomes and fewer days of in-hospital stay.
