Facilitators of and barriers to perinatal telepsychiatry care: a qualitative study.

OBJECTIVES: Perinatal mental health disorders such as anxiety, depression and bipolar disorder can negatively impact the health of women and their children without appropriate detection and treatment. Due to increases in mental health symptoms and transmission risks associated with in-person appointments, many clinics transitioned to providing telepsychiatry care during the COVID-19 pandemic. This study sought to identify the facilitators and barriers to receiving perinatal telepsychiatry care from the perspective of patients, clinic staff and psychiatrists. DESIGN: Qualitative study based on analysis of in depth semistructured interviews. SETTING: The study was conducted in a virtual specialty mental health clinic in an academic setting. PARTICIPANTS: Eight patients who had been scheduled for an appointment with the perinatal telepsychiatry clinic between 14 May 2021 and 1 August 2021, seven of whom had attended their scheduled appointment with the clinic and one of whom had not, and five staff members including psychiatrists, navigators and clinic managers, participated in in-depth interviews. RESULTS: Telepsychiatry was perceived by most as preferable to in-person care and easy to attend and navigate. Alternatively, technological difficulties, personal preference for in-person care and scheduling conflicts related to the perinatal period were identified as barriers by some. Participants identified communication between care staff and patients, online patient portals, and appointment reminders as important for facilitating appointment preparedness and attendance. CONCLUSIONS: The findings from this study suggest that telepsychiatry services are perceived positively by patients and care staff and have the potential to improve access to mental healthcare for perinatal patients.

Ordering and Interpreting Precision Oncology Studies for Adults With Advanced Solid Tumors: A Primer.

Background: The promise of precision oncology can only be realized when genetic alterations are identified that can be leveraged to improve response and minimize toxicity. Identifying those alterations requires the knowledge to order the right test and to interpret the results correctly. This primer is designed to help clinicians order the appropriate testing for patients with specific malignancies and to give them an informed approach to interpretation. Observations: Germline DNA is usually acquired from peripheral blood, buccal swab, or saliva collection in patients with a metastatic malignancy and can provide treatment options otherwise not available. However, germline testing does not indicate alterations that arise solely in tumor tissue. Somatic testing may be performed on primary tumor, metastatic biopsy, or circulating tumor DNA when the alteration is present at the time that the tumor developed and expected to be carried through the evolution of the tumor. Conclusions: The rapid growth in technology and ability to enhance understanding of relevant tumor biology continues to improve the therapeutic landscape for individuals dealing with malignancy as does our ability to find targetable genetic alterations with the potential for meaningful clinical benefit.

Association of Mental Health Treatment With Outcomes for US Veterans Diagnosed With Non-Small Cell Lung Cancer.

Importance: Preexisting mental health disorders (MHDs) are associated with increased mortality in people diagnosed with cancer, yet few data exist on the efficacy of interventions to mitigate this disparity. Objective: To evaluate the association of participation in mental health treatment programs (MHTPs), housing support programs, or employment support programs with stage at cancer diagnosis, receipt of stage-appropriate treatment, and mortality among patients with a preexisting MHD. Design, Setting, and Participants: This retrospective, population-based cohort study included 55 315 veterans in the Veterans Affairs Central Cancer Registry (VACCR) who had newly diagnosed non-small cell lung cancer (NSCLC) from September 30, 2000, to December 31, 2011. Data were analyzed from January 15, 2017, to March 17, 2020. Exposures: Mental health disorders, including schizophrenia, bipolar disorder, depressive disorder, posttraumatic stress disorder, and substance use disorder. Main Outcomes and Measures: Stage at cancer diagnosis, receipt of stage-appropriate cancer treatment, all-cause mortality, and lung cancer-specific mortality. Results: Of 55 315 veterans with a new diagnosis of NSCLC included in the analysis (98.1% men; mean [SD] age, 68.1 [9.8] years), 18 229 had a preexisting MHD, among whom participation in MHTPs was associated with a lower likelihood of being diagnosed in a late stage (odds ratio [OR], 0.62; 95% CI, 0.58-0.66; P < .001), a higher likelihood of receiving stage-appropriate treatment (OR, 1.55; 95% CI, 1.26-1.89; P < .001), lower all-cause mortality (adjusted hazard ratio [AHR], 0.74; 95% CI, 0.72-0.77; P < .001), and lower lung cancer-specific mortality (AHR, 0.77; 95% CI, 0.74-0.80; P < .001). Likewise, participation in housing and employment support programs was associated with similar improvements in all outcomes described above. Conclusions and Relevance: In veterans with preexisting MHDs diagnosed with NSCLC, participation in MHTPs and housing and employment support programs was associated with improved lung cancer-related outcomes. This study might be the first to demonstrate significant improvement in cancer mortality for patients with MHDs who participate in MHTPs, housing support programs, or employment support programs. This work supports substantial literature that investment in mental health and social needs can improve health outcomes and highlights the importance of further research to identify, evaluate, and implement interventions to improve outcomes for patients with MHDs who are diagnosed with cancer.

The Problem of Underrepresentation: Black Participants in Lifestyle Trials Among Patients with Prostate Cancer.

INTRODUCTION: Healthy lifestyle behaviors are an essential component of prostate cancer survivorship; however, it is unknown whether Black participants are adequately represented in randomized controlled trials (RCTs) on lifestyle interventions. The goal of this study was to identify types of lifestyle RCTs that may require improved recruitment resources to enhance generalizability of lifestyle recommendations to Black patients. MATERIALS AND METHODS: ClinicalTrials.gov was used to identify lifestyle RCTs among patients with prostate cancer. Using racial distribution data from the Surveillance, Epidemiology, and End Results (SEER) program as a reference, one-sample proportion tests were performed to assess adequate recruitment of Black participants. RESULTS: Of 31 lifestyle trials, one trial reported race-specific results. Proportion of Black participants was acquired from 26 trials. Compared to the US population, Black participants were overrepresented in the overall study population (17% versus 15%, p = 0.019). Black participants were underrepresented in trials exploring exercise interventions (9% versus 15%, p = 0.041), trials among patients with advanced disease (9% versus 16%, p < 0.001), and in university-funded trials (12% versus 15%, p = 0.026). CONCLUSIONS: The reporting of race data, and race-specific results when feasible, is essential for clinicians to accurately generalize findings from lifestyle trials. Additional resources may be necessary to aid in strategic recruitment of Black participants for trials on exercise interventions, trials among patients with advanced disease, and in university-funded trials.

Association of Receipt of Positron Emission Tomography-Computed Tomography With Non-Small Cell Lung Cancer Mortality in the Veterans Affairs Health Care System.

Importance: Positron emission tomography-computed tomography (PET-CT) has been increasingly used in the management of lung cancer, but its association with survival has not been convincingly documented. Objective: To examine the association of the use of PET-CT with non-small cell lung cancer (NSCLC) mortality in the US Department of Veterans Affairs (VA) health care system from 2000 to 2013. Design, Setting, and Participants: This cohort study included 64 103 veterans receiving care in the VA health care system who were diagnosed with incident NSCLC between September 2000 and December 2013. Data analysis took place in October 2018. Exposure: Use of PET-CT before and/or after diagnosis. Main Outcomes and Measures: All-cause and NSCLC-specific 5-year mortality; secondary outcome was receipt of stage-appropriate treatment. Results: A total of 64 103 veterans with the diagnosis of NSCLC were evaluated; 62 838 (98.0%) were men, and 50 584 (78.9%) were white individuals. Among these, 51 844 (80.9%) had a PET-CT performed: 25 735 (40.1%) in the 12 months before diagnosis and 41 242 (64.3%) in the 5 years after diagnosis. Increased PET-CT use (597 of 978 veterans [59.2%] in 2000 vs 3649 of 3915 [93.2%] in 2013) and decreased NSCLC-specific 5-year mortality (879 of 978 veterans [89.9%] in 2000 vs 3226 of 3915 veterans [82.4%] in 2013) were found over time. Increased use of stage-appropriate therapy was also seen over time, from 346 of 978 veterans (35.4%) in 2000 to 2062 of 3915 (52.7%) in 2013 (P < .001). Increased PET-CT use was associated with higher-complexity level VA facilities (26 127 veterans [82.3%] at level 1a vs 1289 [75.2%] at level 3 facilities; P < .001) and facilities with on-site PET-CT compared with facilities without on-site PET-CT (33 081 [82.2%] vs 17 443 [80.3%]; P < .001). Use of PET-CT before diagnosis was associated with increased likelihood of stage-appropriate treatment for all stages of NSCLC (eg, veterans with stage 1 disease: 4837 of 7870 veterans [61.5%] who received PET-CT underwent surgical resection vs 4042 of 7938 veterans [50.9%] who did not receive PET-CT; P < .001) and decreased mortality in a risk-adjusted model among all participants and among veterans undergoing stage-appropriate treatment (all-cause mortality: hazard ratio [HR], 0.78; 95% CI, 0.77-0.79; NSCLC-specific mortality: HR, 0.78; 95% CI, 0.76-0.80). Facilities with on-site PET-CT and higher-complexity level facilities were associated with a mortality benefit, with 16% decreased mortality at level 1a vs level 3 facilities (HR, 0.84; 95% CI, 0.80-0.89) and a 3% decrease in all-cause mortality in facilities with on-site PET-CT (HR, 0.97; 95% CI, 0.96-0.99). Conclusions: In this study, the use of PET-CT among veterans with NSCLC significantly increased from 2000 to 2013, coinciding with decreased 5-year mortality and an increase in stage-appropriate treatment. Variation in use of PET-CT was found, with the highest use at higher-complexity level facilities and those with PET-CT on-site. These facilities were associated with reduced all-cause and NSCLC-specific mortality.

Real-world lung cancer screening decision-making: Barriers and facilitators.

OBJECTIVE: To explore 1) attitudes and priorities among physicians and patients that inform shared decision-making about lung cancer screening in real-world settings and 2) physician and patient perceptions of shared decision-making in real-world lung cancer screening (LCS) practice. MATERIALS AND METHODS: We conducted a qualitative study of 12 physicians and 30 patients meeting LCS screening criteria established by the US Preventative Services Task Force (USPSTF) from two academic primary care practices; one university clinic and one safety net clinic. Interview guides focused on knowledge and attitudes about LCS and experiences with patient-physician communication. RESULTS: Physicians offered LCS inconsistently and were ambivalent about screening because of potential harms, including false positive results, incidental findings, and radiation exposure. Physicians felt that they were incorporating shared decision-making into screening, although they acknowledged that challenges with screening communication posed barriers to shared decision-making. Patients were generally accepting of lung cancer screening. They expressed fewer concerns about screening-related harms but more personal or emotional concerns related to lung cancer. Patients perceived limited shared decision-making in their encounters, but were generally satisfied with the more physician-directed decision-making process. CONCLUSION: Physicians and patients expressed different concerns about LCS and different perceptions about the use of shared decision-making. Findings from this real-world population of screening-eligible patients can be used to inform the design of future interventions to facilitate communication and decision-making tailored to perspectives of both physicians and patients.

Identification of gammaherpesvirus infection in free-ranging black bears (Ursus americanus).

Herpesvirus infection was investigated in black bears (Ursus americanus) with neurological signs and brain lesions of nonsuppurative encephalitis of unknown cause. Visible cytopathic effects (CPE) could only be observed on days 3-5 post-infection in HrT-18G cell line inoculated with bear tissue extracts. The observed CPE in HrT-18G cells included syncytia, intranuclear inclusions, and cell detachments seen in herpesvirus infection in vitro. Herpesvirus-like particles were observed in viral culture supernatant under the electron microscope, however, capsids ranging from 60 nm to 100 nm in size were often observed in viral cultures within the first two passages of propagation. Herpesvirus infection in the bear tissues and tissue cultures were detected by PCR using degenerate primers specific to the DNA polymerase gene (DPOL) and glycoprotein B gene (gB). DNA sequencing of the amplicon revealed that the detected herpesvirus has 94-95% identity to Ursid gammaherpesvirus 1 (UrHV-1) DNA sequences of DPOL. Phylogenetic analysis of DPOL sequences indicates that black bear herpesviruses and UrHV-1 are closely related and have small distances to members of Rhadinovirus. Interestingly, black bear herpesvirus infections were also found in bears without neurological signs. The DPOL DNA sequence of black bear herpesviruses detected in neurological bears were similar to the those detected in the non-neurological bears. However, the gB DNA sequence detected from the neurological bear is different from non-neurological bear and has only 64.5%-70% identity to each other. It is possible that at least two different types of gammaherpesviruses are present in the U. americanus population or several gammaherpesviruses exist in ursine species.

Electrochemical Modification of Negative Thermal Expansion Materials in the Ta xNb1- xVO5 Series.

Electrochemical processes transfer charge carriers to and from electrodes, e.g., Li+ ions are inserted into anodes during discharge and extracted during charge in a Li half-cell. Using an electrode that features negative thermal expansion (NTE) properties in an electrochemical cell allows a means to study the interaction of the charge carrier with an NTE material and potentially modify or tune its NTE properties. This work examines the NTE properties of Ta xNb1- xVO5 ( x = 1, 0.9, 0.75, 0.5, 0.25) and the effect of Li+/Na+/K+ electrochemical discharge of TaVO5-based electrodes. Sodium discharge was found to drastically alter NTE properties with 25% Na+ discharged electrodes exhibiting a linear volumetric coefficient of thermal expansion of -5.75 ± 0.20 × 10-5 Å3/°C between 350 and 500 °C, one of the largest reported for any NTE system. Furthermore, at higher temperatures, the Na+- and K+-discharged and heated electrodes generate new phases, suggesting that a combination of electrochemical discharge and thermal treatment can be used to synthesize new compounds. This work lays the foundation for the concept of using electrochemical discharge followed by subsequent thermal treatments to modify the physical properties of a compound.

A Large Lateral Craniotomy Procedure for Mesoscale Wide-field Optical Imaging of Brain Activity.

The craniotomy is a commonly performed procedure to expose the brain for in vivo experiments. In mouse research, most labs utilize a small craniotomy, typically 3 mm x 3 mm. This protocol introduces a method for creating a substantially larger 7 mm x 6 mm cranial window exposing most of a cerebral hemisphere over the mouse temporal and parietal cortices (e.g., bregma 2.5 - 4.5 mm, lateral 0 - 6 mm). To perform this surgery, the head must be tilted approximately 30° and much of the temporal muscle must be retracted. Due to the large amount of bone removal, this procedure is intended only for acute experiments with the animal anesthetized throughout the surgery and experiment. The main advantage of this innovative large lateral cranial window is to provide simultaneous access to both medial and lateral areas of the cortex. This large unilateral cranial window can be used to study the neural dynamics between cells, as well as between different cortical areas by combining multi-electrode electrophysiological recordings, imaging of neuronal activity (e.g., intrinsic or extrinsic imaging), and optogenetic stimulation. Additionally, this large craniotomy also exposes a large area of cortical blood vessels, allowing for direct manipulation of the lateral cortical vasculature.

Incidence of non-small-cell lung cancer among California Hispanics according to neighborhood socioeconomic status.

INTRODUCTION: Lung cancer incidence is associated with markers of lower socioeconomic status (SES) in whites, blacks, and Asians but with markers of higher SES in Hispanics. The magnitude and etiology of this positive gradient in Hispanics remain undefined. We examined non-small-cell lung cancer (NSCLC) incidence and ever-smoking rates among California Hispanics according to measures of SES. METHODS: We computed neighborhood (n)SES-specific incidence rates by sex and race or ethnicity for 74,179 NSCLC cases in the California Cancer Registry, 1998-2002. Associations between nSES and NSCLC incidence were examined, using incidence rate ratios and linear trend tests, and stratified by age, stage, and histology. Ever-smoking rates among Hispanics were obtained from California Health Interview Survey 2001 data, and odds ratios for ever-smoking were calculated for measures of SES and acculturation. RESULTS: Compared with the lowest nSES quintile, the NSCLC incidence in the highest quintile was 1.86 and 1.18 times higher for Hispanic women and men, respectively. The positive nSES gradients remained significant for all ages, stages, and nonsquamous histologies in women, and only for older age, local or regional stages, and adenocarcinoma histology in men. Ever-smoking rates were associated with English-speaking households and U.S.-born status for Hispanic women and low education and U.S.-born status for Hispanic men. CONCLUSIONS: For California Hispanics, higher nSES was strongly associated with increased NSCLC incidence in women, but weakly associated in men, and ever-smoking rates were strongly correlated with increased acculturation. This finding may portend an increasing burden of NSCLC in Hispanic women, given future trends in acculturation and SES.

Impact of age and comorbidity on non-small-cell lung cancer treatment in older veterans.

PURPOSE: Because comorbidity affects cancer treatment outcomes, guidelines recommend considering comorbidity when making treatment decisions in older patients with lung cancer. Yet, it is unclear whether treatment is targeted to healthier older adults who might reasonably benefit. PATIENTS AND METHODS: Receipt of first-line guideline-recommended treatment was assessed for 20,511 veterans age ≥ 65 years with non-small-cell lung cancer (NSCLC) in the Veterans Affairs (VA) Central Cancer Registry from 2003 to 2008. Patients were stratified by age (65 to 74, 75 to 84, ≥ 85 years), Charlson comorbidity index score (0, 1 to 3, ≥ 4), and American Joint Committee on Cancer stage (I to II, IIIA to IIIB, IIIB with malignant effusion to IV). Comorbidity and patient characteristics were obtained from VA claims and registry data. Multivariate analysis identified predictors of receipt of guideline-recommended treatment. RESULTS: In all, 51% of patients with local, 35% with regional, and 27% with metastatic disease received guideline-recommended treatment. Treatment rates decreased more with advancing age than with worsening comorbidity for all stages, such that older patients with no comorbidity had lower rates than younger patients with severe comorbidity. For example, 50% of patients with local disease age 75 to 84 years with no comorbidity received surgery compared with 57% of patients age 65 to 74 years with severe comorbidity (P < .001). In multivariate analysis, age and histology remained strong negative predictors of treatment for all stages, whereas comorbidity and nonclinical factors had a minor effect. CONCLUSION: Advancing age is a much stronger negative predictor of treatment receipt among older veterans with NSCLC than comorbidity. Individualized decisions that go beyond age and include comorbidity are needed to better target NSCLC treatments to older patients who may reasonably benefit.

Factor analysis of the clinical characteristics of primary Sjogren syndrome.

PURPOSE: The purpose of this study was to use factor analysis to analyze 90 clinical characteristics of a cohort of 231 patients with primary Sjogren syndrome (pSS). METHODS: The records of all patients seen at the University Health Network Sjogren Syndrome Clinic from October 1992 to July 2006 were reviewed and documented. Those diagnosed as pSS by the American European Consensus Criteria of 2002 were included. The 90 clinical variables, including health history, blood analysis, symptoms of dry eye and dry mouth, salivary flow and biopsy, tear flow and staining, were analyzed by factor analysis. RESULTS: Two hundred thirty-one patients with pSS charts were reviewed, and 90 variables were recorded. Factor analysis resulted in three factors: factor 1: ocular surface staining, factor 2: antimicrosomal antibodies and antithyroid antibodies, and factor 3: serum anti-Ro and anti-La. CONCLUSIONS: Ocular surface staining accounted for the greatest variance in this population of patients with pSS.

Health-related quality of life is reduced in pediatric multiple sclerosis.

The health-related quality of life of children with multiple sclerosis was compared with that of healthy children and of those with other neurologic diseases. The Pediatric Quality of Life Inventory Version 4.0 was administered to children with multiple sclerosis and clinically isolated syndrome and their parents (proxy reporters) at the University of California, San Francisco (UCSF), Regional Pediatric Multiple Sclerosis Center. Scores were compared with those of siblings and to those of children seen at the UCSF Pediatric Muscular Dystrophy Association Center. After adjustment for age and sex, children with multiple sclerosis or clinically isolated syndrome (P = 0.003) and their parents (P = 0.001) reported worse overall health-related quality of life than their siblings. Although overall scores for those with early multiple sclerosis or clinically isolated syndrome were better than for children with neuromuscular disease, their self-reported psychosocial scores were similar. The main predictor of reduced self-reported health-related quality of life among children with multiple sclerosis or clinically isolated syndrome was greater neurologic disability, whereas parents reported worse scores for girls, older children, and those with longer disease duration. Although it is better than for children with chronic neuromuscular diseases, children with multiple sclerosis or clinically isolated syndrome have substantial reductions in health-related quality of life.

Rose bengal staining of the temporal conjunctiva differentiates Sjögren's syndrome from keratoconjunctivitis sicca.

PURPOSE: To compare the clinical presentation of 231 patients with primary Sjögren's syndrome (pSS) with 89 patients with aqueous-deficient dry eye (keratoconjunctivitis sicca; KCS), to determine those procedures that best differentiate these groups in the eye care clinic. METHODS: The records of all patients seen at the University Health Network Sjögren's Syndrome Clinic from October 1992 to July 2006 were reviewed and documented. The diagnosis of pSS was based on the AECC (American European Consensus Criteria) of 2002. KCS control subjects were non-SS patients with symptoms of dry eye and Schirmer scores of

STIM1 signalling controls store-operated calcium entry required for development and contractile function in skeletal muscle.

It is now well established that stromal interaction molecule 1 (STIM1) is the calcium sensor of endoplasmic reticulum stores required to activate store-operated calcium entry (SOC) channels at the surface of non-excitable cells. However, little is known about STIM1 in excitable cells, such as striated muscle, where the complement of calcium regulatory molecules is rather disparate from that of non-excitable cells. Here, we show that STIM1 is expressed in both myotubes and adult skeletal muscle. Myotubes lacking functional STIM1 fail to show SOC and fatigue rapidly. Moreover, mice lacking functional STIM1 die perinatally from a skeletal myopathy. In addition, STIM1 haploinsufficiency confers a contractile defect only under conditions where rapid refilling of stores would be needed. These findings provide insight into the role of STIM1 in skeletal muscle and suggest that STIM1 has a universal role as an ER/SR calcium sensor in both excitable and non-excitable cells.

Direct observation of microbial adhesion to membranes.

Direct microscopic observation and an interfacial force model were used to better understand and control microbial adhesion to polymeric ultrafiltration membranes. The model was used to predict a "critical flux", below which cells deposited reversibly, and direct observation was used to visually quantify cell deposition and removal. In preliminary direct observation experiments, permeate reversal (backpulsing) was more effective than cross-flow hydrodynamics at removing deposited cells. In experiments conducted below the critical flux, no cell accumulation was observed over repeated forward-reverse filtration cycles; however, a small fraction of cells deposited irreversibly regardless of the flux, membrane, or solution chemistry. The fraction of irreversibly deposited cells was consistent with the equilibrium surface coverage attained without permeation (i.e., due to heterogeneous adsorption). Although steric forces were not invoked to establish a critical flux, when operating above the critical flux, a balance between permeation drag and steric repulsion appeared to determine the strength of adhesion of cells to membranes. Direct observation also confirmed that above the critical flux fouling occurred and pressure losses accumulated over several backpulse cycles, whereas below the critical flux there were no observable pressure losses or fouling.
