ABSTRACT

Metastasis occurs frequently after resection of pancreatic cancer (PaC). In this study, we hypothesized that multi-parametric analysis of pre-metastatic liver biopsies would classify patients according to their metastatic risk, timing and organ site. Liver biopsies obtained during pancreatectomy from 49 patients with localized PaC and 19 control patients with non-cancerous pancreatic lesions were analyzed, combining metabolomic, tissue and single-cell transcriptomics and multiplex imaging approaches. Patients were followed prospectively (median 3 years) and classified into four recurrence groups; early (<6 months after resection) or late (>6 months after resection) liver metastasis (LiM); extrahepatic metastasis (EHM); and disease-free survivors (no evidence of disease (NED)). Overall, PaC livers exhibited signs of augmented inflammation compared to controls. Enrichment of neutrophil extracellular traps (NETs), Ki-67 upregulation and decreased liver creatine significantly distinguished those with future metastasis from NED. Patients with future LiM were characterized by scant T cell lobular infiltration, less steatosis and higher levels of citrullinated H3 compared to patients who developed EHM, who had overexpression of interferon target genes (MX1 and NR1D1) and an increase of CD11B+ natural killer (NK) cells. Upregulation of sortilin-1 and prominent NETs, together with the lack of T cells and a reduction in CD11B+ NK cells, differentiated patients with early-onset LiM from those with late-onset LiM. Liver profiles of NED closely resembled those of controls. Using the above parameters, a machine-learning-based model was developed that successfully predicted the metastatic outcome at the time of surgery with 78% accuracy. Therefore, multi-parametric profiling of liver biopsies at the time of PaC diagnosis may determine metastatic risk and organotropism and guide clinical stratification for optimal treatment selection.

ABSTRACT

During the COVID-19 pandemic, adults with chronic conditions delayed or avoided seeking preventative and general medical care, leading to adverse consequences for morbidity and mortality. In order to bring patients back into care, we, in this qualitative study, sought to understand the foremost health-related needs of our multi-morbid ambulatory patients to inform future outreach interventions. Via a telephone-based survey of our high-risk patients, defined using a validated EPIC risk model for hospitalization and ED visits, we surveyed 214 participants an open-ended question, "What is your top health concern that you would like to speak with a doctor or nurse about". We found 4 major themes: 1) primary care matters, 2) disruptions in health care, 3) COVID-19's impact on physical and mental health, and 4) amplified social vulnerabilities. Our results suggest that interventions that reduce barriers to preventative services and disruptions to healthcare delivery are needed.

ABSTRACT

STUDY DESIGN: This is a prospective observational study. OBJECTIVE: The aim was to record daily opioid use and pain levels after 1-level or 2-level anterior cervical discectomy and fusion (ACDF) or cervical disc arthroplasty (CDA). SUMMARY OF BACKGROUND DATA: Data to inform opioid prescription guidelines following ACDF or CDA is lacking. Understanding postoperative opioid consumption behaviors is critical to provide appropriate postdischarge prescriptions. METHODS: Patients undergoing 1-level or 2-level primary ACDF or CDA were consecutively enrolled at 2 participating institutions between March 2018 and March 2019. Patients with opioid dependence (defined as daily use ≥6 mo before surgery) were excluded. Starting postoperative day 1, daily opioid use and numeric pain rating scale pain levels were collected through a Health Insurance Portability and Accountability Act-compliant, automated text-messaging system. To facilitate clinical applications, opioid use was converted from oral morphine equivalents into "pills" (oxycodone 5 mg equivalents). After 6 weeks or upon patient-reported cessation of opioid use, final survey questions were asked. Refill data were verified from the state prescription registry. Risk factors for patients in top quartile of consumption were analyzed. RESULTS: Of 57 patients, 48 completed the daily queries (84.2%). Mean age of the patient sample was 50.2±10.9 years. Thirty-two patients (66.7%) underwent ACDF and 16 CDA (33.3%); 64.6% one level; 35.4% two levels. Median postdischarge use was 6.7 pills (range: 0-160). Cumulative opioid use did not vary between the 1-level and 2-level groups (median pill consumption, 10 interquartile range: 1.3-31.3 vs. 4 interquartile range: 0-18, respectively, P=0.085). Thirteen patients (27.1%) did not use any opioids after discharge. Of those patients that took opioids after discharge, half ceased opioids by postoperative day 8. Preoperative intermittent opioid use was associated with the top quartile of opioid consumption (9.1% vs. 50%, P=0.006). CONCLUSION: Given that most patients use few opioids, patients could be offered the option of a 12 oxycodone 5 mg (90 oral morphine equivalents) discharge prescription, accompanied by education on appropriate opioid use and disposal.

ABSTRACT

STUDY DESIGN: Prospective observational study OBJECTIVE.: The aim of this study was to record daily opioid use and pain levels after 1-level lumbar decompression or microdiscectomy. SUMMARY OF BACKGROUND DATA: The standardization of opioid-prescribing practices through guidelines can decrease the risk of misuse and lower the number of pills available for diversion in this high-risk patient population. However, there is a paucity of quantitative data on the "minimum necessary amount" of opioid appropriate for post-discharge prescriptions. METHODS: At two institutions between September 2017 and 2018, we prospectively enrolled 85 consecutive adult patients who underwent one-level lumbar decompression or microdiscectomy. Patients with a history of opioid dependence were excluded. Daily opioid consumption and pain scores were collected using an automated text-messaging-based platform for 6 weeks or until consumption ceased. Refills during the study period were monitored. Patients were asked for the number of pills left over and the method of disposal. Opioid use was converted to oral morphine equivalents (OMEs). Results are also reported in terms of "pills" (oxycodone 5 mg equivalents) to facilitate clinical applications. Risk factors were compared between patients in the top and bottom half of opioid consumption. RESULTS: Total opioid consumption ranged from 0 to 118 pills, with a median consumption of 32 pills (236.3 OME). Seventy-five percent of patients consumed ≤57 pills (431.3 OME). Mean Numeric Rating Scale pain scores declined steadily over the first 2 weeks. By postoperative day 7 half of the study population had ceased taking opioids altogether. Only 22.4% of patients finished their initial prescription, and only 9.4% of patients obtained a refill. CONCLUSION: These data may be used to formulate evidence-based opioid prescription guidelines, establish benchmarks, and identify patients at the higher end of the opioid use spectrum. LEVEL OF EVIDENCE: 2.

ABSTRACT

In the United States, 15% of HIV-positive individuals do not know their HIV serostatus. While CDC guidelines recommend HIV testing for individuals age 13-64 years, racial and ethnic minorities continue to experience delays in HIV diagnosis. We assessed providers' perspectives on HIV testing at an urban community health center serving racial/ethnic minority populations of low socioeconomic status. We conducted five focus groups from January 2017 to November 2017 with 74 health center staff: 20 adult medicine/primary care providers, 34 community health workers (CHWs) and community health administrators, six urgent care physicians, and fourteen behavioral health providers. Study staff analyzed transcripts using a grounded theory approach and used open coding to develop themes. We identified five themes affecting HIV testing: 1) provider perception of patients' preferences for HIV testing; 2) competing medical and social issues; 3) inter-professional communication; 4) knowledge of clinical indicators for HIV testing; and 5) knowledge of frequency of HIV testing. Primary care physicians desired mechanisms to easily identify patients for HIV testing and assistance with testing for non-English speakers. Training to improve comfort with HIV testing, integrating CHWs into routine practice, and focusing on patients' cultural beliefs may increase HIV testing in diverse community health centers..

ABSTRACT

Latino immigrants with substance use and mental health problems are at risk for undiagnosed HIV and sexually transmitted infections (STIs). Participants in a randomized control trial were recruited in Boston, USA and Madrid and Barcelona, Spain. Eligibility criteria were Latino self-identification, age 18-70, elevated substance use and mental health symptoms, and not currently in substance or mental health care. A multinomial logistic regression examined predictors of HIV/STI testing decline and lost to follow-up (LTFU) prior to testing compared with acceptance. Of 341 participants, 74% accepted testing, 4% declined, and 22% were LTFU. The odds of LTFU were higher in those with high concern for HIV and those whose main partner had done HIV testing. Age ≥ 35 years, females, higher education, and higher report of discrimination lowered the odds of LTFU. Delivery of HIV/STI testing through community agencies and outreach could overcome barriers to HIV/STI diagnosis in this population of Latinos.Clinical Trial Number: NCT02038855.

ABSTRACT

Latino immigrants in the United States are disproportionately affected by HIV. Barriers to consistent attendance (retention) in HIV primary care constrain opportunities for HIV treatment success, but have not been specifically assessed in this population. We conducted semistructured interviews with 37 HIV-infected Latinos (aged ≥18 years and born in Puerto Rico or a Latin American Spanish-speaking country) and 14 HIV providers in metropolitan Boston (total n = 51). The Andersen Model of Healthcare Utilization informed a semistructured interview guide, which bilingual research staff used to explore barriers to HIV care. We used thematic analysis to explore the processes of retention in care. Six ubiquitous themes were perceived to influence HIV clinic attendance: (1) stigma as a barrier to HIV serostatus disclosure; (2) social support as a safety net during negative life circumstances; (3) unaddressed trauma and substance use leading to interruption in care; (4) a trusting relationship between patient and provider motivating HIV clinic attendance; (5) basic unmet needs competing with the perceived value of HIV care; and (6) religion providing a source of hope and optimism. Cultural subthemes were the centrality of family (familismo), masculinity (machismo), and trusting relationships (confianza). The timing of barriers was acute (e.g., eviction) and chronic (e.g., family conflict). These co-occurring and dynamic constellation of factors affected HIV primary care attendance over time. HIV-infected Latino immigrants and migrants experienced significant challenges that led to interruptions in HIV care. Anticipatory guidance to prepare for these setbacks may improve retention in HIV care in this population.
