RESUMEN
IMPORTANCE: The Latina population is the largest growing ethnic group in the United States with high levels of health disparities in urinary incontinence (UI) treatment and complications rates, which may be due to disproportionately high barriers to UI care-seeking among Latinas. OBJECTIVES: The objectives of this study were to compare barriers to UI care-seeking among Latina, non-Latina Black, and non-Latina White patients by utilizing the Barriers to Incontinence Care Seeking Questionnaire (BICS-Q) total scores, and to compare specific barriers utilizing BICS-Q subscales. STUDY DESIGN: In this cross-sectional study, patients accessing primary care were recruited to complete the BICS-Q, International Consultation on Incontinence Questionnaire-Short Form, and Prolapse and Incontinence Knowledge Questionnaire-Urinary Incontinence. The BICS-Q total and subscale scores were compared among ethnic/racial groups. RESULTS: A total of 298 patients were included in the study with 83 Black, 144 Latina, and 71 White participants per self-identified ethnicity/race. The total BICS-Q score was highest for Latina participants, followed by White and Black participants (11.2 vs 8.2 vs 4.9, respectively, P < 0.0001). Latina participants had significantly higher BICS-Q subscale scores compared with Black participants with no significant differences between Latina and White participants. After controlling for potential confounders, Latina ethnicity/race was still associated with a higher BICS-Q score when compared to Black ethnicity/race (P = 0.0077), and lower Prolapse and Incontinence Knowledge Questionnaire-Urinary Incontinence scores remained independently associated with higher BICS-Q scores (P = 0.0078). CONCLUSIONS: In our study population, Latina patients and patients with lower UI knowledge experience higher barriers to UI care-seeking compared with Black patients and patients with higher UI knowledge. Addressing these barriers may increase care-seeking and improve health equity in the field.
RESUMEN
Objectives: Risk assessment models for cardiac surgery do not distinguish between degrees of liver dysfunction. We have previously shown that preoperative liver stiffness is associated with hospital length of stay following cardiac surgery. The authors hypothesized that a liver stiffness measurement (LSM) ≥ 9.5 kPa would rule out a short hospital length of stay (LOS < 6 days) following isolated coronary artery bypass grafting (CABG) surgery. Methods: A prospective observational study of one hundred sixty-four adult patients undergoing non-emergent isolated CABG surgery at a single university hospital center. Preoperative liver stiffness measured by ultrasound elastography was obtained for each participant. Multivariate logistic regression models were used to assess the adjusted relationship between LSM and a short hospital stay. Results: We performed multivariate logistic regression models using short hospital LOS (<6 days) as the dependent variable. Independent variables included LSM (< 9.5 kPa, ≥ 9.5 kPa), age, sex, STS predicted morbidity and mortality, and baseline hemoglobin. After adjusting for included variables, LSM ≥ 9.5 kPa was associated with lower odds of early discharge as compared to LSM < 9.5 kPa (OR: 0.22, 95% CI: 0.06-0.84, p = 0.03). The ROC curve and resulting AUC of 0.76 (95% CI: 0.68-0.83) suggest the final multivariate model provides good discriminatory performance when predicting early discharge. Conclusions: A preoperative LSM ≥ 9.5 kPa ruled out a short length of stay in nearly 80% of patients when compared to patients with a LSM < 9.5 kPa. Preoperative liver stiffness may be a useful metric to incorporate into preoperative risk stratification.
RESUMEN
INTRODUCTION: The optimal protocol for serial amnioinfusions to maintain amniotic fluid in pregnancies with early-onset fetal renal anhydramnios before 22 weeks is not known. We compared the performance of two different approaches. METHODS: A secondary analysis was conducted of serial amnioinfusions performed by a single center during the external pilot and feasibility phases of the Renal Anhydramnios Fetal Therapy (RAFT) trial. During the external pilot, higher amnioinfusion volumes were given less frequently; in the feasibility study, smaller volume amnioinfusions were administered more frequently. Procedural details, complications, and obstetric outcomes were compared between the two groups using Pearson's χ2 or Fisher's exact tests for categorical variables and Student's t tests or Wilcoxon rank-sum tests for continuous variables. The adjusted association between procedural details and chorioamniotic separation was obtained through a multivariate repeated measure logistic regression model. RESULTS: Eleven participants underwent 159 amnioinfusions (external pilot: 3 patients, 21 amnioinfusions; feasibility: 8 patients, 138 amnioinfusions). External pilot participants had fewer amnioinfusions (7 vs. 19.5 in the feasibility group, p = 0.04), larger amnioinfusion volume (750 vs. 500 mL, p < 0.01), and longer interval between amnioinfusions (6 [4-7] vs. 4 [3-5] days, p < 0.01). In the external pilot, chorioamniotic separation was more common (28.6% vs. 5.8%, p < 0.01), preterm prelabor rupture of membranes (PPROM) occurred sooner after amnioinfusion initiation (28 ± 21.5 vs. 75.6 ± 24.1 days, p = 0.03), and duration of maintained amniotic fluid between first and last amnioinfusion was shorter (38 ± 17.3 vs. 71 ± 19 days, p = 0.03), compared to the feasibility group. While delivery gestational age was similar (35.1 ± 1.7 vs. 33.8 ± 1.5 weeks, p = 0.21), feasibility participants maintained amniotic fluid longer. CONCLUSION: Small volume serial amnioinfusions performed more frequently maintain normal amniotic fluid volume longer because of delayed occurrence of PPROM.
RESUMEN
BACKGROUND: Telehealth technologies offer efficient ways to deliver health-related social needs (HRSN) screening in cancer care, but these methods may not reach all populations. The authors examined patient characteristics associated with using an online patient portal (OPP) to complete HRSN screening as part of gynecologic cancer care. METHODS: From June 2021 to June 2023, patients in a gynecologic oncology clinic completed validated HRSN screening questions either (1) using the OPP (independently before the visit) or (2) in person (verbally administered by clinic staff). The authors examined the prevalence of HRSN according to activated OPP status and, in a restricted subgroup, used stepwise multivariate Poisson regression to identify associations between patient and visit characteristics and using the OPP. RESULTS: Of 1616 patients, 87.4% (n = 1413) had an activated OPP. Patients with inactive OPPs (vs. activated OPPs) more frequently reported two or more needs (10% vs 5%; p < .01). Of 986 patients in the restricted cohort, 52% used the OPP to complete screening. The final multivariable model indicated that patients were less likely to use the OPP if they were Black (vs. White; adjusted relative risk [aRR], 0.70; 95% confidence interval [CI], 0.59-0.83); not employed (vs. employed; aRR, 0.81; 95% CI, 0.68-0.97), or had low measures of OPP engagement (aRR, 0.80; 95% CI, 0.68-0.92). New versus established patients were 21% more likely to use the OPP (aRR, 1.21; 95% CI, 1.06-1.38). CONCLUSIONS: Differential use of the OPP suggested that over-reliance on digital technologies could limit the ability to reach those populations that have social factors already associated with cancer outcome disparities. Cancer centers should consider using multiple delivery methods for HRSN screening to maximize reach to all populations.
RESUMEN
Importance: Despite a growing population of survivors of lung cancer, there is limited understanding of the survivorship journey. Survivors of lung cancer experience unmet physical, social, emotional, and medical needs regardless of stage at diagnosis or treatment modalities. Objective: To investigate the association of unmet needs with quality of life (QOL) and financial toxicity (FT) among survivors of lung cancer. Design, Setting, and Participants: This survey study was conducted at Johns Hopkins Sidney Kimmel Comprehensive Cancer Center thoracic oncology clinics between December 1, 2020, and September 30, 2021, to assess needs (physical, social, emotional, and medical), QOL, and FT among survivors of lung cancer. Patients had non-small cell lung cancer of any stage and were alive longer than 1 year from diagnosis. A cross-sectional survey was administered, which consisted of an adapted needs survey developed by the Mayo Survey Research Center, the Comprehensive Score for Financial Toxicity measure, and the European Organization for Research and Treatment of Cancer QLQ-C30 QOL scale. Demographic and clinical information was obtained through retrospective medical record review. Data analysis was performed between May 9 and December 8, 2022. Main Outcomes and Measures: Separate multiple linear regression models, treating QOL and FT as dependent variables, were performed to assess the adjusted association of total number of unmet needs and type of unmet need (physical, emotional, social, or medical) with QOL and FT. Results: Of the 360 survivors of lung cancer approached, 232 completed the survey and were included in this study. These 232 respondents had a median age of 69 (IQR, 60.5-75.0) years. Most respondents were women (144 [62.1%]), were married (165 [71.1%]), and had stage III or IV lung cancer (140 [60.3%]). Race and ethnicity was reported as Black (33 [14.2%]), White (172 [74.1%]), or other race or ethnicity (27 [11.6%]). A higher number of total unmet needs was associated with lower QOL (ß [SE], -1.37 [0.18]; P < .001) and higher FT (ß [SE], -0.33 [0.45]; P < .001). In the context of needs domains, greater unmet physical needs (ß [SE], -1.24 [0.54]; P = .02), social needs (ß [SE], -3.60 [1.34]; P = .01), and medical needs (ß [SE], -2.66 [0.98]; P = .01) were associated with lower QOL, whereas only greater social needs was associated with higher FT (ß [SE], -3.40 [0.53]; P < .001). Conclusions and Relevance: The findings of this survey study suggest that among survivors of lung cancer, unmet needs were associated with lower QOL and higher FT. Future studies evaluating targeted interventions to address these unmet needs may improve QOL and FT among survivors of lung cancer.

Many pregnant people learn of fetal anomalies in the second trimester and subsequently present to prenatal genetic counselors (PGCs) for counseling, including but not limited to a nuanced discussion about whether to continue or terminate pregnancy. In those who choose to terminate, the decision between dilation and evacuation (D&E) or induction is often one of patient preference and as such, is heavily influenced by the quality of counseling received. PGCs are expertly trained to provide values-based counseling, yet little is known about their termination counseling practices, referral practice patterns, and perceived responsibilities in caring for this group of pregnant people. To gain this knowledge, we surveyed a national sample of PGCs in early 2022 and received 70 completed responses. The survey contained open- and closed-ended questions. Data were analyzed using descriptive statistics, and free response data were analyzed using inductive content analysis. Eighty percent (n = 56) of respondents reported that <50% of their patients had previously received termination options counseling. Most strikingly, 15% of respondents provided termination counseling that was beyond their self-identified comfort level. Scenario-based questions assessed respondents' counseling practice patterns in seven real-world situations, presented in order of decreasing severity for the fetus. Respondents were 50% less likely to provide termination options counseling to patients between the most lethal to the least lethal proposed fetal anomaly. The scenario-based analysis revealed two distinct termination counseling approaches: (1) all options counseling with an explicit discussion of options to continue or terminate and (2) discretionary options counseling focused on identifying patient preferences to guide counseling and not explicitly stating all available options. This study highlights the need to ensure PGCs feel well-trained to discuss the general features of second trimester pregnancy termination and, if unable to do so, to practice in systems with timely referral to providers well-versed in the counseling about all methods of termination.
RESUMEN
Wildlife trafficking creates favorable scenarios for intra- and inter-specific interactions that can lead to parasite spread and disease emergence. Among the fauna affected by this activity, primates are relevant due to their potential to acquire and share zoonoses - infections caused by parasites that can spread between humans and other animals. Though it is known that most primate parasites can affect multiple hosts and that many are zoonotic, comparative studies across different contexts for animal-human interactions are scarce. We conducted a multi-parasite screening targeting the detection of zoonotic infections in wild-caught monkeys in nine Peruvian cities across three contexts: captivity (zoos and rescue centers, n = 187); pet (households, n = 69); and trade (trafficked or recently confiscated, n = 132). We detected 32 parasite taxa including mycobacteria, simian foamyvirus, bacteria, helminths, and protozoa. Monkeys in the trade context had the highest prevalence of hemoparasites (including Plasmodium malariae/brasilianum, Trypanosoma cruzi, and microfilaria) and enteric helminths and protozoa were less common in pet monkeys. However, parasite communities showed overall low variation between the three contexts. Parasite richness (PR) was best explained by host genus and the city where the animal was sampled. Squirrel (genus Saimiri) and wooly (genus Lagothrix) monkeys had the highest PR, which was ~2.2 times the PR found in tufted capuchins (genus Sapajus) and tamarins (genus Saguinus/Leontocebus) in a multivariable model adjusted for context, sex, and age. Our findings illustrate that the threats of wildlife trafficking to One Health encompass exposure to multiple zoonotic parasites well-known to cause disease in humans, monkeys, and other species. We demonstrate these threats continue beyond the markets where wildlife is initially sold; monkeys trafficked for the pet market remain a reservoir for and contribute to the translocation of zoonotic parasites to households and other captive facilities where contact with humans is frequent. Our results have practical applications for the healthcare of rescued monkeys and call for urgent action against wildlife trafficking and ownership of monkeys as pets.

BACKGROUND: Newer therapies prolong survival for patients with lung cancer. Beyond extending survival, the needs of lung cancer (LC) survivors are poorly described. METHODS: We conducted a single-institution needs assessment survey of LC survivors alive ≥1 year from diagnosis. Needs were rated on a 5-point Likert scale for 4 domains (physical, social, emotional, and medical). Multiple regression models identified demographic or treatment characteristics associated with more needs in each category. A subset analysis of survivors with metastatic LC was performed. RESULTS: Of 360 patients approached, 235 surveys were completed. Among completed survey respondents, the median age was 69 years; most were female (62%), married (71%), and White (74%); and 41% had stage IV cancer. Finding support resources (34%) was the most common medical need. Fatigue (70%), sleep disturbance (60%), memory and concentration (57.5%), weakness (54%), and trouble breathing (51%) were physical needs affecting more than half of respondents. The most common social need was managing daily activities (42%). Emotional needs were highly prevalent, with 79% of respondents reporting a fear of recurrence and 74.5% reporting living with uncertainty. Multiple regression analysis identified that receipt of multiple lines of systemic therapy and lower household income were associated with higher physical and social needs. Younger age was associated with having a greater number of social and emotional needs. Similar results were found in the subset of survivors with metastatic disease at diagnosis. CONCLUSIONS: The needs of LC survivors are diverse across multiple domains. Several clinical and demographic factors are independently associated with higher numbers of patient-reported needs. Our study identifies critical gaps in survivorship care for LC survivors with all stages of disease and highlights areas of future intervention.

OBJECTIVES: To investigate the impact of adding 68Ga-DOTATATE PET/MRI to standard MRI for target volume delineation in Gamma Knife® stereotactic radiosurgery (GKSRS) for meningioma. METHODS: Seventeen patients with 18 lesions undergoing GKSRS for WHO grade 1 meningioma were enrolled in a prospective study. All patients underwent pre-treatment 68Ga-DOTATATE PET/MRI examination in addition to standard procedures. Five clinicians independently contoured the gross tumour volume (GTV) based on standard MRI (GTVMRI) and PET/MRI (GTVPET/MRI) on separate occasions. Interobserver agreement was evaluated using Cohen's Kappa statistic (CKS), Dice similarity coefficient (DC), and Hausdorff distance (HD). Statistical analysis was performed with paired t-test and Wilcoxon signed rank test. RESULTS: The addition of PET/MRI significantly increased GTV contour volume (mean GTVPET/MRI 3.59 cm3 versus mean GTVMRI 3.18 cm3, P = .008). Using the treating clinician's pre-treatment GTVMRI as the reference, median CKS (87.2 vs 77.5, P = .006) and DC (87.2 vs 77.4, P = .006) were significantly lower, and median HD (25.2 vs 31.0, P = .001) was significantly higher with the addition of PET/MRI. No significant difference was observed in interobserver contouring reproducibility between GTVMRI and GTVPET/MRI. CONCLUSION: The addition of 68Ga-DOTATATE PET/MRI for target volume delineation in GKSRS for meningioma is associated with an increase in GTV volume and greater interobserver variation. PET/MRI did not affect interobserver contouring reproducibility. ADVANCES IN KNOWLEDGE: This study provides novel insights into the impact of 68Ga-DOTATATE PET/MRI on GTV delineation and interobserver agreement in meningioma GKSRS, highlighting its potential for improving GKSRS treatment accuracy.

INTRODUCTION: Major traumatic injury is associated with early hemorrhage-related and late-stage deaths due to multiple organ failure (MOF). While improvements to hemostatic resuscitation have significantly reduced hemorrhage-related deaths, the incidence of MOF among trauma patients remains high. Dysregulation of vascular endothelial cell (EC) barrier function is a central mechanism in the development of MOF; however, the mechanistic triggers remain unknown. Accelerated fibrinolysis occurs in a majority of trauma patients, resulting in high circulating levels of fibrin(ogen) degradation products, such as fragment X. To date, the relationship between fragment X and EC dysregulation and barrier disruption is unknown. The goal of this study was to determine the effects of fragment X on EC barrier integrity and expression of paracellular junctional proteins that regulate barrier function. METHODS: Human lung microvascular endothelial cells (HLMVECs) were treated with increasing concentrations of fragment X (1, 10, and 100 µg/mL), and barrier function was monitored using the xCELLigence live-cell monitoring system. Quantitative PCR (qPCR) was performed to measure changes in EC expression of 84 genes. Immunofluorescent (IF) cytostaining was performed to validate qPCR findings. RESULTS: Fragment X treatment significantly increased endothelial permeability over time (P < 0.05). There was also a significant reduction in VE-cadherin mRNA expression in fragment X-treated HLMVECs compared to control (P = 0.01), which was confirmed by IF staining. CONCLUSIONS: Fragment X may induce EC hyperpermeability by reducing VE-cadherin expression. This suggests that a targeted approach to disrupting EC-fragment X interactions could mitigate EC barrier disruption, organ edema, and MOF associated with major trauma.

BACKGROUND: The majority of maternal deaths occur in the postpartum period. We sought to compare postpartum readmission by race and ethnicity to better understand whether there are disparities in maternal health in the postpartum period as indicated by readmission to the hospital. OBJECTIVE: This study aimed to use state-wide Maryland data to identify postpartum readmission rates by race and ethnicity, as well as the major risk factors, indications, and timing of readmission. STUDY DESIGN: In this retrospective study (2016-2019), childbirth hospitalizations for patients of childbearing age were identified from the Maryland State Inpatient Database, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality. Indication for readmission was described. Multivariable logistic regression models were employed to determine racial and ethnic differences in postpartum readmissions, adjusting for maternal and obstetrical characteristics. RESULTS: Among total deliveries (n=260,778), 3914 patients (1.5%) were readmitted within 60 days of delivery. The most common primary diagnoses at readmission were hypertension and infection. The prevalence of readmission was 1.2% (1306/111,325) for White patients, 2.3% (1786/79,412) for Black patients, 1.2% (485/40,862) for Hispanic patients and 1.2% (337/29,179) for patients of Other race or ethnicity (P<.0001). Black patients had the highest rates of readmission for hypertensive disorders as compared with all other races (37%, P<.0001). In adjusted models, Black patients were more likely to be readmitted than White patients (odds ratio, 1.64; confidence interval, 1.52-1.77). The majority of all readmissions occurred in the first week after delivery with Black patients having higher rates of readmission in the second week relative to all other groups (P<.0001). CONCLUSION: Hypertension is a leading cause of postpartum readmission in Maryland. Black patients were more likely to be readmitted for hypertensive disorders of pregnancy and to have delayed readmission relative to other race or ethnic groups. Maryland public health officials should address disparities with interventions targeting racial and ethnic minorities, patients at risk for hypertensive disorders, and barriers to timely care.
RESUMEN
BACKGROUND: Since 2005, highly pathogenic avian influenza A H5N1 viruses have spread from Asia worldwide, infecting poultry, humans and wild birds. Subsequently, global interest in avian influenza (AI) surveillance increased. OBJECTIVES: Mongolia presents an opportunity to study viruses in wild birds because the country has very low densities of domestic poultry and supports large concentrations of migratory water birds. METHODS: We conducted AI surveillance in Mongolia over two time periods, 2009-2013 and 2016-2018, utilizing environmental fecal sampling. Fresh fecal samples were collected from water bird congregation sites. Hemagglutinin (HA) and neuraminidase (NA) subtypes of positive samples were identified through viral isolation or molecular assays, with pathogenicity determined by HA subtype or sequencing the HA cleavage site. RESULTS: A total of 10,222 samples were collected. Of these, 7,025 fecal samples were collected from 2009 to 2013, and 3,197 fecal samples were collected from 2016 to 2018. Testing revealed 175 (1.7%) positive samples for low-pathogenicity influenza A, including 118 samples from 2009 to 2013 (1.7%) and 57 samples from 2016 to 2018 (1.8%). HA and NA subtyping of all positives identified 11 subtypes of HA and nine subtypes of NA in 29 different combinations. Within periods, viruses were detected more frequently during the fall season than in the early summer. CONCLUSION: Mongolia's critical wild bird habitat is positioned as a crossroad of multiple migratory flyways. Our work demonstrates the feasibility of using an affordable environmental fecal sampling approach for AI surveillance and contributes to understanding the prevalence and ecology of low-pathogenicity avian influenza viruses in this important location, where birds from multiple flyways mix.

Importance: An estimated 1.5% to nearly 5% of medications are dispensed after discontinuation in the electronic health record (EHR), with 34% meeting criteria for high risk of potential harm. Objective: To evaluate the association of the implementation of e-prescription cancellation messaging (CancelRx) with medication dispensing after discontinuation of e-prescriptions in the EHR. Design, Setting, and Participants: This case series with interrupted time series analysis included patients who had at least 1 medication e-prescribed in ambulatory care to a health system pharmacy and discontinued in the 2-year study period from 1 year prior to approximately 1 year after CancelRx implementation (January 15, 2018, to December 7, 2019). Prior to CancelRx implementation, changes to e-prescribed medications within the EHR were not electronically communicated to health system pharmacies, which used separate pharmacy management software. Statistical analysis was performed from November 2020 to June 2023 (primary analysis from March 2021 to May 2022). Exposure: Implementation of CancelRx. Main Outcomes and Measures: The primary outcome was the proportion of e-prescribed medications dispensed and sold to patients by pharmacies within 6 months after discontinuation in the EHR. A medication was defined as dispensed after discontinuation if the timestamp of dispensing was at least 1 minute and less than 6 months after the timestamp of discontinuation in the EHR. A secondary outcome was the proportion of discontinued medications that was reordered within 120 days. Results: A total of 53â¯298 qualifying e-prescriptions that were discontinued were identified for 17â¯451 unique patients (mean [SD] age, 50.6 [18.2] years; 9332 women [53.5%]). After CancelRx implementation, 22â¯443 (85.9%) of the 26â¯127 discontinued e-prescriptions resulted in a CancelRx transaction. In interrupted time series analysis, the proportion of prescriptions dispensed after discontinuation decreased from a baseline of 8.0% (2162 of 27â¯171) to 1.4% (369 of 26â¯127; P < .001), without a significant week-to-week trend (ß = 0.000158; P = .37). Conclusions and Relevance: In this case series with interrupted time series analysis, findings suggest that CancelRx implementation was associated with an immediate and persistent reduction in the proportion of e-prescriptions sold after discontinuation in the EHR. Widespread implementation of CancelRx may significantly improve medication safety through the reduction of medication dispensing after discontinuation by prescribers.

We describe a case of lumpy skin disease in an endangered banteng in Cambodia and the subsequent initiation of a vaccination campaign in domestic cattle to protect wild bovids from disease transmission at the wildlife-livestock interface. Lumpy skin disease virus (LSDV) was first detected in domestic cattle in Cambodia in June of 2021 and rapidly spread throughout the country. In September 2021, a banteng was seen in Phnom Tnout Phnom Pok wildlife sanctuary with signs of lumpy skin disease. Scab samples were collected and tested positive for LSDV. Monitoring using line transect surveys and camera traps in protected areas with critical banteng and gaur populations was initiated from December 2021-October 2022. A collaborative multisector vaccination campaign to vaccinate domestic livestock in and around priority protected areas with banteng and gaur was launched July 2022 and a total of 20,089 domestic cattle and water buffalo were vaccinated with LumpyvaxTM. No signs of LSDV in banteng or gaur in Cambodia have been observed since this initial case. This report documents the first case of lumpy skin disease in wildlife in Cambodia and proposes a potential intervention to mitigate the challenge of pathogen transmission at the domestic-wildlife interface. While vaccination can support local livestock-based economies and promote biodiversity conservation, it is only a component of an integrated solution and One Health approach to protect endangered species from threats at the wildlife-livestock interface.
RESUMEN
Left-hemisphere intraparenchymal primary brain tumor patients are at risk of developing reading difficulties that may be stable, improve or deteriorate after surgery. Previous studies examining language organization in brain tumor patients have provided insights into neural plasticity supporting recovery. Only a single study, however, has examined the role of white matter tracts in preserving reading ability post-surgery and none have examined the functional reading network. The current study aimed to investigate the regional spontaneous brain activity associated with reading performance in a group of 36 adult patients 6-24 months following left-hemisphere tumor resection. Spontaneous brain activity was assessed using resting-state fMRI (rs-fMRI) regional homogeneity (ReHo) and fractional amplitude low frequency fluctuation (fALFF) metrics, which measure local functional connectivity and activity, respectively. ReHo in the left occipito-temporal and right superior parietal regions was negatively correlated with reading performance. fALFF in the putamen bilaterally and the left cerebellum was negatively correlated with reading performance, and positively correlated in the right superior parietal gyrus. These findings are broadly consistent with reading networks reported in healthy participants, indicating that reading ability following brain tumor surgery might not involve substantial functional re-organization.

During cell division, the microtubule nucleating and organizing organelle, known as the centrosome, is a critical component of the mitotic spindle. In cells with two centrosomes, each centrosome functions as an anchor point for microtubules, leading to the formation of a bipolar spindle and progression through a bipolar cell division. When extra centrosomes are present, multipolar spindles form and the parent cell may divide into more than two daughter cells. Cells that are born from multipolar divisions are not viable, and hence clustering of extra centrosomes and progression to a bipolar division are critical determinants of viability in cells with extra centrosomes. We combine experimental approaches with computational modeling to define a role for cortical dynein in centrosome clustering. We show that centrosome clustering fails and multipolar spindles dominate when cortical dynein distribution or activity is experimentally perturbed. Our simulations further reveal that centrosome clustering is sensitive to the distribution of dynein on the cortex. Together, these results indicate that dynein's cortical localization alone is insufficient for effective centrosome clustering and, instead, dynamic relocalization of dynein from one side of the cell to the other throughout mitosis promotes timely clustering and bipolar cell division in cells with extra centrosomes.

Surgical resection of brain tumours is associated with an increased risk of aphasia. However, relatively little is known about outcomes in the chronic phase (i.e., >6 months). Using voxel-based lesion symptom mapping (VLSM) in 46 patients, we investigated whether chronic language impairments are related to the location of surgical resection, residual tumour characteristics (e.g., peri-resection treatment effects, progressive infiltration, oedema) or both. Approximately 72% of patients scored below the cut-off for aphasia. Action naming and spoken sentence comprehension deficits were associated with lesions in the left anterior temporal and inferior parietal lobes, respectively. Voxel-wise analyses revealed significant associations between ventral language pathways and action naming deficits. Reading impairments were also associated with increasing disconnection of cerebellar pathways. The results indicate chronic post-surgical aphasias reflect a combination of resected tissue and tumour infiltration of language-related white matter tracts, implicating progressive disconnection as the critical mechanism of impairment.

A One Health cross-sectoral surveillance approach was implemented to screen biological samples from bats, pigs, and humans at high-risk interfaces for zoonotic viral spillover for five viral families with zoonotic potential in Viet Nam. Over 1600 animal and human samples from bat guano harvesting sites, natural bat roosts, and pig farming operations were tested for coronaviruses (CoVs), paramyxoviruses, influenza viruses, filoviruses and flaviviruses using consensus PCR assays. Human samples were also tested using immunoassays to detect antibodies against eight virus groups. Significant viral diversity, including CoVs closely related to ancestors of pig pathogens, was detected in bats roosting at the human-animal interfaces, illustrating the high risk for CoV spillover from bats to pigs in Viet Nam, where pig density is very high. Season and reproductive period were significantly associated with the detection of bat CoVs, with site-specific effects. Phylogeographic analysis indicated localized viral transmission among pig farms. Our limited human sampling did not detect any known zoonotic bat viruses in human communities living close to the bat cave and harvesting bat guano, but our serological assays showed possible previous exposure to Marburg virus-like (Filoviridae), Crimean-Congo hemorrhagic fever virus-like (Bunyaviridae) viruses and flaviviruses. Targeted and coordinated One Health surveillance helped uncover this viral pathogen emergence hotspot.
