RESUMEN

BACKGROUND & AIMS: Direct-acting antivirals (DAAs) are highly effective for treating HCV infection even among people who inject drugs (PWID). Yet, little is known about patients' adherence patterns and their association with sustained virologic response (SVR) rates. We aimed to summarize various adherence patterns and determine their associations with SVR. METHODS: Electronic blister packs were used to measure daily adherence to once-a-day sofosbuvir/velpatasvir during the 12-week treatment period among active PWIDs. Blister pack data were available for 496 participants who initiated DAAs for whom SVR status was known. Adherence was summarized in multiple patterns, such as total adherent days, consecutive missed days, and early discontinuations. Thresholds for adherence patterns associated with >90% SVR rates were also determined. RESULTS: The overall SVR rate was 92.7%, with a median adherence rate of 75%. All adherence patterns indicating greater adherence were significantly associated with achieving SVR. Participant groups with ≥50% (>42/84) adherent days or <26 consecutive missed days achieved an SVR rate of >90%. Greater total adherent days during 9-12 weeks and no early discontinuation were significantly associated with higher SVR rates only in those with <50% adherence. Participants with first month discontinuation and ≥2 weeks of treatment interruption had low SVR rates, 25% and 85%, respectively. However, greater adherent days were significantly associated with SVR (adjusted odds ratio 1.10; 95% CI 1.04-1.16; p <0.001) even among participants with ≥14 consecutive missed days. CONCLUSIONS: High SVR rates can be achieved in the PWID population despite suboptimal adherence. Encouraging patients to take as much medication as possible, with <2 weeks consecutive missed days and without early discontinuation, was found to be important for achieving SVR. IMPACT AND IMPLICATIONS: People who inject drugs can be cured of HCV in >90% of cases, even with relatively low adherence to direct-acting antivirals, but early discontinuations and long treatment interruptions can significantly reduce the likelihood of achieving cure. Clinicians should encourage people who inject drugs who are living with HCV to adhere daily to direct-acting antivirals as consistently as possible, but if any days are interrupted, to continue and complete treatment. These results from the HERO study are important for patients living with HCV, clinicians, experts writing clinical guidelines, and payers. CLINICAL TRIAL NUMBER: NCT02824640.

RESUMEN

BACKGROUND: Self-reported adherence to direct-acting antivirals (DAAs) to treat hepatitis C virus (HCV) among persons who inject drugs (PWID) is often an overreport of objectively measured adherence. The association of such overreporting with sustained virologic response (SVR) is understudied. This study among PWID aimed to determine a threshold of overreporting adherence that optimally predicts lower SVR rates, and to explore correlates of the optimal overreporting threshold. METHODS: This study analyzed per-protocol data of participants with adherence data (N = 493) from the HERO (Hepatitis C Real Options) study. Self-reported and objective adherence to a 12-week DAA regimen were measured using visual analogue scales and electronic blister packs, respectively. The difference (Δ) between self-reported and objectively measured adherence was calculated. We used the Youden index based on receiver operating characteristic (ROC) curve analysis to identify an optimal threshold of overreporting for predicting lower SVR rates. Factors associated with the optimal threshold of overreporting were identified by comparing baseline characteristics between participants at/above versus those below the threshold. RESULTS: The self-reported, objective, and Δ adherence averages were 95.1% (SD = 8.9), 75.9% (SD = 16.3), and 19.2% (SD = 15.2), respectively. The ≥ 25% overreporting threshold was determined to be optimal. The SVR rate was lower for ≥ 25% vs. < 25% overreporting (86.7% vs. 95.8%, p <.001). The factors associated with ≥ 25% Δ adherence were unemployment; higher number of days and times/day of injecting drugs; higher proportion of positive urine drug screening for amphetamine, methamphetamine, and oxycodone, and negative urine screening for THC (tetrahydrocannabinol)/cannabis. CONCLUSIONS: Self-reported DAA adherence was significantly greater than objectively measured adherence among PWID by 19.2%. Having ≥ 25% overreported adherence was associated with optimal prediction of lower SVR rates. PWID with risk factors for high overreporting may need to be more intensively managed to promote actual adherence.

RESUMEN

BACKGROUND: Female Mexican Immigrants (FMIs) experience high rates of depression compared with other populations. For this population, depression is often exacerbated by social isolation associated with the experience of immigration. Aim 1. To measure whether a culturally situated peer group intervention will reduce depression and stress associated with the experience of immigration. Aim 2. To test whether an intervention using a "women's funds of knowledge" approach results in improved resilience, knowledge and empowerment. Aim 3. To investigate whether a culturally situated peer group intervention using a women's funds of knowledge approach can give participants a sense and experience of social and physical connection ("emplacement") that is lost in the process of immigration. METHODS: This mixed-methods study will implement "Tertulias" ("conversational gatherings" in Spanish), a peer support group intervention designed to improve health outcomes for FMI participants in Albuquerque, New Mexico. We will document results of the intervention on our primary hypotheses of a decrease in depression, and increases in resilience and social support, as well as on our secondary hypotheses of decreased stress (including testing of hair cortisol as a biomarker for chronic stress), and an increase in social connectedness and positive assessment of knowledge and empowerment. DISCUSSION: This project will address mental health disparities in an underserved population that experiences high rates of social isolation. Successful completion of this project will demonstrate that health challenges that may appear too complex and too hard to address can be using a multi-level, holistic approach. Our use of hair samples to test for the 3-month average levels of systemic cortisol will contribute to the literature on an emerging biomarker for analyzing chronic stress. TRIAL REGISTRATION: This study was registered with ClinicalTrials.gov on 2/3/20, Identifier # NCT04254198 .

RESUMEN

BACKGROUND: Few studies have evaluated the impact of Baby Friendly Hospital Initiative (BFHI) implementation on underserved populations in the United States. We undertook this study in New Mexico, a large southwestern state with a diverse population and limited health care access. METHODS: A quasi-experimental, retrospective cohort design was used to compare short-term breastfeeding duration between a pre-BFHI and a post-BFHI cohort. Among the post-BFHI cohort, logistic regression models were fitted to predict short-term breastfeeding duration from both individual and cumulative exposure to inpatient maternity care practices (Steps 4 to 9). RESULTS: Implementation of the BFHI and cumulative exposure to the Ten Steps increased short-term duration of any breastfeeding and exclusive breastfeeding at 2-6 weeks postpartum. Exposure to all six of the inpatient Ten Steps increased the odds of any breastfeeding by 34 times and exclusive breastfeeding by 24 times. Exposure to Step 9 ("Give no pacifiers or artificial nipples") uniquely increased the likelihood of any breastfeeding at 2-6 weeks postpartum by 5.7 times, whereas Step 6 ("Give infants no food or drink other than breastmilk") increased the rate of exclusive breastfeeding by 4.4 times at 2-6 weeks postpartum. CONCLUSION: These findings demonstrate that the Baby Friendly Hospital Initiative can have a positive impact on breastfeeding among underserved populations.

RESUMEN

This randomized controlled non-inferiority trial explored the effectiveness of Seeking Safety (SS) delivered by peer providers compared to its delivery by licensed behavioral health clinicians. The study enrolled 291 adults with PTSD and/or substance use disorders. Data were collected at 3 and 6-months post start of treatment. With respect to long-term outcomes, at 6 months PTSD symptoms decreased by 5.1 points [95% CI (- 9.0, - 1.1)] and by 4.9 points [95% CI (- 8.6, - 1.1)] and coping skills increased by 5.5 points [95% CI (0.4, 10.6)] and by 5.6 points [95% CI (0.8, 10.4)], in the peer- and clinician-led groups, respectively. This study demonstrated non-inferiority of peer-delivered SS compared to clinician-delivered SS for reducing PTSD symptoms and similar outcomes for both groups with respect to coping skills. A confirmatory study on the effectiveness of peer-delivered trauma-specific services is warranted, especially given the potential for increasing access to such treatment in underserved rural communities.

RESUMEN

LESSONS LEARNED: Colorectal cancers exhibit a high level of cyclooxygenase-2 (COX-2) expression with strong preclinical rationale for improved clinical outcomes with COX-2 inhibition. Celecoxib is a COX-2 inhibitor and we have shown that it can be safely combined with capecitabine and oxaliplatin as part of neoadjuvant treatment with radiation therapy (RT) in rectal cancer.There was a significant improvement in skin toxicity with this combination as compared with historical data. Considering the field has moved on to single-agent capecitabine, we believe future trials with capecitabine and celecoxib hold potential. BACKGROUND: Improved survival is seen among patients with rectal cancer who achieve pathologic complete response (pCR) after neoadjuvant therapy. Cyclooxygenase-2 (COX-2) expression is increased in gastrointestinal malignancies and it may serve as a target to enhance pathologic response. A trial combining chemoradiation and COX-2 inhibition was conducted to evaluate the pCR rate, surgical outcomes, survival, and treatment toxicity. METHODS: Patients with resectable (T3-4, N1-2) rectal cancer within 12 cm of the anal verge were included in this phase II clinical trial. The neoadjuvant treatment consisted of capecitabine 850 mg/m2 b.i.d. Monday through Friday for 5 weeks, weekly oxaliplatin 50 mg/m2 intravenous (IV), celecoxib 200 mg b.i.d. daily, along with concurrent 45 gray radiation therapy in 25 fractions. RESULTS: Thirty-two patients were included in the final analysis. The primary endpoint was pCR: 31% (95% confidence interval [CI]: 16%-50%). Secondary endpoints were surgical downstaging (SD): 75% (95% CI: 57%-89%) and sphincter-sparing surgery (SSS): 56% (95% CI: 38%-74%). Common grade >3 toxicities were diarrhea and abnormal liver function tests (9% each). Grade 0 and 1 toxicities included radiation dermatitis (59% and 34%, respectively) and proctitis (63% and 28%, respectively). At 3 years, disease-free survival and overall survival (OS) were 84% (95% CI: 65%-93%) and 94% (95% CI: 77%-98%), respectively. CONCLUSION: Chemoradiation with celecoxib in rectal cancer was well tolerated and demonstrated high rates of pCR, SD, and SSS. Improvement in skin toxicity (34% grade 1 and no grade 3/4) as compared with historical results (43%-78% grade 3/4) seems to be a significant improvement with addition of celecoxib to neoadjuvant chemotherapy.

RESUMEN

BACKGROUND: Nonsteroidal antiinflammatory drug use has been shown to increase blood pressure in nonpregnant adults. Because of this, the American College of Obstetricians and Gynecologists suggests avoiding their use in women with postpartum hypertension; however, evidence to support this recommendation is lacking. OBJECTIVE: Our goal was to test the hypothesis that nonsteroidal antiinflammatory drugs, such as ibuprofen, adversely affect postpartum blood pressure control in women with preeclampsia with severe features. STUDY DESIGN: At delivery, we randomized women with preeclampsia with severe features to receive around-the-clock oral dosing with either 600 mg of ibuprofen or 650 mg of acetaminophen every 6 hours. Dosing began within 6 hours after delivery and continued until discharge, with opioid analgesics available as needed for breakthrough pain. Study drugs were encapsulated in identical capsules such that patients, nurses, and physicians were masked to study allocation. Exclusion criteria were serum aspartate aminotransferase or alanine aminotransferase >200 mg/dL, serum creatinine >1.0 mg/dL, infectious hepatitis, gastroesophageal reflux disease, age <18 years, or current incarceration. Our primary outcome was the duration of severe-range hypertension, defined as the time (in hours) from delivery to the last blood pressure ≥160/110 mm Hg. Secondary outcomes were time from delivery to last blood pressure ≥150/100 mm Hg, mean arterial pressure, need for antihypertensive medication at discharge, prolongation of hospital stay for blood pressure control, postpartum use of short-acting antihypertensives for acute blood pressure control, and opioid use for breakthrough pain. We analyzed all outcome data according to intention-to-treat principles. RESULTS: We assessed 154 women for eligibility, of whom 100 met entry criteria, agreed to participate, and were randomized to receive postpartum ibuprofen or acetaminophen for first-line pain control. Seven patients crossed over or did not receive their allocated study drug, and 93 completed the study protocol in their assigned groups. We found no differences in baseline characteristics between groups, including mode of delivery, body mass index, parity, race, chronic hypertension, and maximum blood pressure prior to delivery. We did not find a difference in the duration of severe-range hypertension in the ibuprofen vs acetaminophen groups (35.3 vs 38.0 hours, P = .30). There were no differences between groups in the secondary outcome measures of time from delivery to last blood pressure ≥150/100 mm Hg, postpartum mean arterial pressure, maximum postpartum systolic or diastolic blood pressures, any postpartum blood pressure ≥160/110 mm Hg, short-acting antihypertensive use for acute blood pressure control, length of postpartum stay, need to extend postpartum stay for blood pressure control, antihypertensive use at discharge, or opioid use for inadequate pain control. In a subgroup analysis of patients who experienced severe-range hypertension, the mean time to blood pressure control in the acetaminophen group was 68.4 hours and ibuprofen group was 56.7 hours (P = .26). At 6 weeks postpartum, there were no differences between groups in the rates of obstetric triage visits, hospital readmissions, continued opioid use, or continued antihypertensive use. CONCLUSION: The first-line use of ibuprofen rather than acetaminophen for postpartum pain did not lengthen the duration of severe-range hypertension in women with preeclampsia with severe features.

RESUMEN

BACKGROUND: Diabetes risk is extremely high for Latinos from low-income households. Health guidelines recommend that individuals learn strategies to self-manage their diabetes, but getting people to adopt required lifestyle changes is challenging and many people are not able to prevent their pre-diabetes from escalating or effectively control their diabetes. Systematic reviews show that culturally competent self-management programs can significantly improve diabetes outcomes and different models for culturally competent programming have been developed. METHODS: This patient-engaged study will compare the effectiveness of two distinct evidence-based models for culturally competent diabetes health promotion at two sites that serve a large Latino patient population from low-income households: 1) The Diabetes Self-Management Support Empowerment Model, an educational session approach, and 2) The Chronic Care Model, a holistic community-based program. Data collection will involve interviews, focus groups, surveys and assessments of each program; and testing of patient participants for A1c, depression, Body Mass Index (BMI), and chronic stress with hair cortisol levels. We will recruit a total of 240 patient-social support pairs: Patients will be adults (men and women over the age of 18) who: 1.) Enter one of the two diabetes programs during the study; 2.) Self-identify as "Latino;" 3.) Are able to identify a social support person or key member of their social network who also agrees to participate with them; 4.) Are not pregnant (participants who become pregnant during the study will be excluded); and 5.) Have household income 250% of the Federal Poverty Level (FPL) or below. Social supports will be adults who are identified by the patient participants. PRIMARY OUTCOME: Improved capacity for diabetes self-management measured through improvements in diabetes knowledge and diabetes-related patient activation. SECONDARY OUTCOME: Successful diabetes self-management as measured by improvements in A1c, depression scale scores, BMI, and circulating levels of cortisol to determine chronic stress. DISCUSSION: Our hypothesis is that the program model that interfaces most synergistically with patients' culture and everyday life circumstances will have the best diabetes health outcomes. TRIAL REGISTRATION: This study was registered with ClinicalTrials.gov on December 16, 2016 (Registration # NCT03004664 ).

RESUMEN

BACKGROUND: The role of aggressive surgical manipulation with clot evacuation, arachnoid dissection, and papaverine-guided adventitial dissection of large vessels during ruptured aneurysm surgery in reducing vasospasm is controversial. Here we describe a single-institution experience in aneurysm surgery outcomes with and without aggressive surgery. METHODS: We performed retrospective analysis of all patients >18 years of age with subarachnoid hemorrhage (SAH) from anterior circulation aneurysms between 2008 and 2013 at the University of New Mexico Hospital. Vasospasm was characterized on days 3 through 14 after SAH based on: (1) angiography, (2) vasospasm requiring angiographic intervention, (3) development of delayed ischemic neurologic deficit (DIND), and (4) radiological appearance of new strokes. RESULTS: Of 159 patients, 114 (71.6%) had "aggressive" and 45 (28.3%) had standard microsurgery. More than 60% of patients presented with a Hunt and Hess score of ≥3 and a Fisher grade (FG) of 4. Compared with standard surgery, there was a statistically significant decrease in the incidence of DIND in patients undergoing aggressive surgery (18.4% vs 37.8%, p=0.01). Moreover, there was a reduction in the number of new strokes by 30% in the aggressive surgery group with moderate or higher degrees of vasospasm (46.0% vs 76.5%, p=0.06). In the same group with FG 4 SAH, however, this difference was more than 50% (30% vs 64.7%, p=0.02). CONCLUSIONS: We conclude that aggressive surgical manipulation during aneurysm surgery results in lower incidence of DIND and new strokes. This effect is most pronounced in patients with FG 4 SAH.

RESUMEN

BACKGROUND: We undertook this prospective, randomized, surgeon-blinded study to compare the accuracy of using of a magnification marker on preoperative radiographs for templating vs using a standard 21% magnification. METHODS: One hundred consecutive total hip arthroplasties were randomized to preoperative templating using a 25-mm magnification marker (50 patients) or a standard 21% magnification (50 patients). Intraoperative data were collected regarding the actual and predicted size of the femoral and acetabular components. RESULTS: The 2 groups were found to be comparable with respect to body mass index (28.9 vs 27.9, P = .26) and gender (P = .69). In the magnification marker group, we predicted the femoral size within 1 size in 80% of the cases and the acetabular component in 94%. In the group of a standard 21% magnification, we predicted the femoral size within 1 size in 90% of the cases and the acetabular component in 96%. These proportions did not statistically differ (femur: χ2P = .16, odds ratio = 2.3, 95% confidence interval = 0.7-7.1; acetabulum: χ2P = .65, odds ratio = 1.5, 95% confidence interval = 0.3-9.6). CONCLUSION: We did not detect a statistically significant difference in accuracy by using one method over the other when comparing the accuracy of component size selection. As the use of the magnification marker adds to the time and expense of preoperative radiographic acquisition, we feel using a standard 21% magnification is an equally accurate technique.

RESUMEN

BACKGROUND: With the ubiquity of digital radiographs, the use of digital templating for arthroplasty has become commonplace. Although improved accuracy with digital radiographs and magnification markers is assumed, it has not been shown. QUESTIONS/PURPOSES: We wanted to (1) evaluate the accuracy of magnification markers in estimating the magnification of the true hip and (2) determine if the use of magnification markers improves on older techniques of assuming a magnification of 20% for all patients. METHODS: Between April 2013 and September 2013 we collected 100 AP pelvis radiographs of patients who had a THA prosthesis in situ and a magnification marker placed per the manufacturer's instructions. Radiographs seen during our standard radiographic review process, which met our inclusion criteria (AP pelvic view that included a well-positioned and observed magnification marker, and a prior total hip replacement with a known femoral head size), were included in the analysis. We then used OrthoView(TM) software program to calculate magnification of the radiograph using the magnification marker (measured magnification) and the femoral head of known size (true magnification). RESULTS: The mean true magnification using the femoral head was 21% (SD, 2%). The mean magnification using the marker was 15% (SD, 5%). The 95% CI for the mean difference between the two measurements was 6% to 7% (p < 0.001). The use of a magnification marker to estimate magnification at the level of the hip using standard radiographic techniques was shown in this study to routinely underestimate the magnification of the radiograph using an arthroplasty femoral head of known diameter as the reference. If we assume a magnification of 20%, this more closely approximated the true magnification routinely. With this assumption, we were within 2% magnification in 64 of the 100 hips and off by 4% or more in only four hips. In contrast, using the magnification marker we were within 2% of true magnification in only 20 hips and were off by 4% or more in 59 hips. CONCLUSION: We found the use of a magnification marker with digital radiographs for preoperative templating to be generally inaccurate, with a mean error of 6% and range from -5% to 15%. Additionally, these data suggest that the use of a magnification marker while taking preoperative radiographs of the hip may be unnecessary, as simply setting the software to assume a 20% magnification actually was more accurate. LEVEL OF EVIDENCE: Level III, diagnostic study.

RESUMEN

The reported incidence of post-allogeneic HSCT AIHA was between 4.4% and 6% following a single transplant. Cord blood transplantation, T-cell depletion, and chronic GvHD are significantly associated with post-transplant AIHA. During an 11-yr period, data for 500 pediatric HSCT recipients were eligible for evaluation of the incidence of AIHA post-first and post-second transplants. Demographic, transplant, and post-transplant-related variables were analyzed. Twelve of 500 (2.4%) recipients at a median of 273 days and seven of 72 (9.7%) recipients at a median of 157 days developed AIHA post-first and post-second HSCT, respectively. Post-first HSCT, none of the MRD recipients developed AIHA (0/175 MRD vs. 12/325 other donors, p = 0.04). Four of 12 required a second HSCT to control the AIHA. After the second HSCT, MUD was significantly associated with the development of AIHA. No other variables were associated with the post-second transplant AIHA. The incidence of AIHA post-first and post-second HSCT was less than the reported. The increased incidence of AIHA among recipients of second HSCT is most likely due to the profound immune dysregulation. A much larger, prospective study would be needed to evaluate the incidence, complications, and management of post-transplant AIHA.

RESUMEN

CONTEXT: Coronary heart disease is the leading cause of death worldwide, and its incidence is rapidly accelerating in developing nations. Patients often search for therapies that are alternatives to traditional treatments, such as heart medicines, coronary bypass surgery, or coronary stenting. Ayurveda is an ancient, East Indian, holistic approach to health care, and its use has never been formally evaluated for patients with coronary heart disease. OBJECTIVES: The study intended to examine the feasibility and effectiveness of comprehensive ayurvedic therapy-incorporating diet, meditation, breathing exercises, yoga, and herbs-for patients with established coronary heart disease. DESIGN: The study was a prospective, single-group, pilot study. SETTING: The study took place at the University of New Mexico Cardiology Clinic and at the Ayurvedic Institute in Albuquerque, NM, USA. PARTICIPANTS: The participants were adults with a history of a prior heart attack, coronary bypass surgery, or a coronary intervention (ie, a coronary angioplasty and/or stent). INTERVENTION: All enrolled patients were evaluated by a single ayurvedic physician with >40 y of experience, and each received therapy consisting of a calorically unrestricted ayurvedic diet; instruction in yoga, meditation, and breathing; and use of ayurvedic herbs. OUTCOME MEASURES: The primary endpoint was arterial pulse wave velocity, a marker of arterial function and vascular health. Secondary endpoints included the following measurements: (1) body mass index (BMI); (2) blood pressure (BP) and amount of reduction in BP medications; and (3) levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides. All parameters were measured at baseline and after 90 d of therapy. RESULTS: Twenty-two patients were enrolled in the study, and 19 patients completed it. The research team observed significant improvements in arterial pulse wave velocity (P = .015), and favorable reductions in BMI (P < .0001), total cholesterol (P = .028), LDL cholesterol (P = .024), and triglycerides (P = .046). HDL cholesterol did not change significantly (P = .90). A majority of hypertensive patients were able to reduce or eliminate their antihypertensive medications (P = .0058). CONCLUSIONS: The study's results suggest a favorable effect for ayurveda on arterial function and multiple risk factors in patients with established coronary heart disease.

RESUMEN

OBJECTIVE: The research tested the accuracy of the VIVO Harvester software in identifying publications authored by faculty members affiliated with a National Institutes of Health Clinical and Translational Sciences Award (CTSA) site. METHODS: Health sciences librarians created "gold standard" lists of references for the years 2001 to 2011 from PubMed for twenty-five randomly selected investigators from one CTSA site. These gold standard lists were compared to the same twenty-five investigators' reference lists produced by VIVO Harvester. The authors subjected the discrepancies between the lists to sensitivity and specificity analyses. RESULTS: The VIVO Harvester correctly identified only about 65% of the total eligible PubMed references for the years 2001-2011 for the CTSA-affiliated investigators. The identified references produced by VIVO Harvester were precise yet incomplete. The sensitivity rate was 0.65, and the specificity rate was 1.00. CONCLUSION: While the references produced by VIVO Harvester could be confirmed in PubMed, the VIVO Harvester retrieved only two-thirds of the required references from PubMed. National Institutes of Health CTSA sites will need to supplement VIVO Harvester-produced references with the expert searching skills of health sciences librarians. IMPLICATIONS: Health sciences librarians with searching skills need to alert their CTSA sites about these deficiencies and offer their skills to advance their sites' missions.

RESUMEN

This parallel-group, randomized controlled pilot study examined daily meditation in a diverse sample of older adults with postherpetic neuralgia. Block randomization was used to allocate participants to a treatment group (n = 13) or control group (n = 14). In addition to usual care, the treatment group practiced daily meditation for six weeks. All participants completed questionnaires at enrollment in the study, two weeks later, and six weeks after that, at the study's end. Participants recorded daily pain and fatigue levels in a diary, and treatment participants also noted meditation practice. Results at the 0.10 level indicated improvement in neuropathic, affective, and total pain scores for the treatment group, whereas affective pain worsened for the control group. Participants were able to adhere to the daily diary and meditation requirements in this feasibility pilot study.

RESUMEN

BACKGROUND: There is debate in the trauma literature regarding the effect of prolonged prehospital transport on morbidity and mortality. This study analyzes the management of hepatic trauma patients requiring surgery and compares the outcomes of the group that was transferred to the University of New Mexico Hospital (UNMH) from outside institutions, to the directly admitted group. MATERIALS AND METHODS: The UNMH Trauma Database was queried from 2005-2012. Of 674 patients who sustained liver injuries, 163 required surgery: 46 patients (28.2%) underwent interhospital transfer, and 117 (71.8%) were directly admitted. Variables examined included transfer status, trauma mechanism, transport type, injury severity score (ISS), liver injury grade, and associated injuries. Outcome variables included length of stay (LOS) and 30-day mortality. Outcomes of the transfer group (TG) and direct admit group (DAG) were compared. RESULTS: Both TG and DAG had the same median age (31 y, P = 0.33). The blunt-to-penetrating ratio was the same for each group (48% blunt: 52% penetrating, P = 1.0). Median ISS was 25 for the TG and 26 for the DAG. Grade III or higher injury occurred in 29 (63%) of the TG and in 68 (58%) of the DAG (P = 0.56). Median hospital LOS was 14 d for TG and 9 d for DAG (P = 0.15). Median intensive care unit LOS was 4 d for both groups (P = 0.71). Thirty-day mortality was 20% in each group (P = 0.27). Using a multiple logistic regression model for the outcome of mortality, only age, ISS, and liver injury grade, not transfer status or transport type, had a significant effect on mortality. CONCLUSIONS: There was no significant difference in liver injury grade, ISS, LOS, and mortality between TG and DAG. In the patient population of our study, transfer status did not affect outcome.

RESUMEN

OBJECTIVE: Programs for early detection of psychosis help identify individuals experiencing emerging psychosis and link them with appropriate services, thereby reducing the duration of untreated psychosis (DUP). The authors used the cascade-of-care framework to identify various care stages between screening and enrollment in coordinated specialty care (CSC) and to determine attrition at each stage, with the goal of identifying points in the referral process that may affect DUP. METHODS: Project partners included a college counseling center and CSC program. All college students seeking mental health services at a counseling center between 2020 and 2022 (N=1,945) completed the Prodromal Questionnaire-Brief (PQ-B) at intake. Students who met the distress cutoff score were referred for a phone screening. Those who met criteria on the basis of this screening were referred for assessment and possible enrollment into CSC. RESULTS: Six stages in the cascade of care for early detection were identified. Of the students who completed the PQ-B as part of intake (stage 1), 547 (28%) met the PQ-B cutoff score (stage 2). Counselors referred 428 (78%) students who met the PQ-B cutoff score (stage 3), and 212 (50%) of these students completed the phone screening (stage 4). Seventy-two (34%) students completed a CSC eligibility assessment (stage 5), 21 (29%) of whom were enrolled in CSC (stage 6). CONCLUSIONS: The cascade-of-care framework helped conceptualize the flow within a program for early psychosis detection in order to identify stages that may contribute to lengthier DUP. Future research is warranted to better understand the factors that contribute to DUP at these stages.

RESUMEN

This article demonstrates how digital information and communication technologies (ICTs) (Zoom/WhatsApp) unexpectedly and counterintuitively proved to be valuable tools for community-engaged health research when, in the context of the COVID-19 pandemic, they were integrated into a research study testing a peer support group intervention with female immigrants from Mexico. Because of pandemic restrictions, we changed the study protocol to hold meetings remotely via Zoom rather than in person as originally planned. Because we recognized that this would lack some opportunities for participants to interact and develop relationships, we created a WhatsApp chat for each group. Despite challenges for participants to use ICTs and participant-stated preference for in-person meetings, the results demonstrated that participants overwhelmingly endorsed these technologies as promoting access, participation, engagement, and satisfaction. Zoom/WhatsApp created a valuable environment both as a method for conducting research with this population, but also as part of the intervention for immigrant women to support and learn from each other. ICT adaptations have now permanently changed the way we conduct community-engaged health research.
