Opioid Use Patterns in a Statewide Adult Medicaid Population Undergoing Elective Lumbar Spine Surgery.

STUDY DESIGN: Retrospective administrative database review. OBJECTIVE: Analyze patterns of opioid use in patients undergoing lumbar surgery and determine associated risk factors in a Medicaid population. SUMMARY OF BACKGROUND DATA: Opioid use in patients undergoing surgery for degenerative lumbar spine conditions is prevalent and impacts outcomes. There is limited information defining the scope of this problem in Medicaid patients. MATERIALS AND METHODS: Longitudinal cohort study of adult South Carolina (SC) Medicaid patients undergoing lumbar surgery from 2014 to 2017. All patients had continuous SC Medicaid coverage for 15 consecutive months, including six months before and nine months following surgery. The primary outcome was a longitudinal assessment of postoperative opioid use to determine trajectories and group-based membership using latent modeling. Univariate and multivariable modeling was conducted to assess risk factors for group-based trajectory modeling and chronic opioid use (COU). RESULTS: A total of 1455 surgeries met inclusion criteria. Group-based trajectory model demonstrated patients fit into five groups; very low use (23.4%), rapid wean following surgery (18.8%), increasing use following surgery (12.9%), slow wean following surgery (12.6%) and sustained high use (32.2%). Variables predicting membership in high opioid use included preoperative opioid use, younger age, longer length of stay, concomitant medications, and readmissions. More than three quarter of patients were deemed COUs (76.4%). On bivariate analysis, patients with degenerative disk disease were more likely to be COUs (24.8% vs. 18.6%; P =0.0168), more likely to take opioids before surgery (88.5% vs. 61.9%; P <0.001) and received higher amounts of opioids during the 30 days following surgery (mean morphine milligram equivalents 59.6 vs. 25.1; P <0.001). CONCLUSIONS: Most SC Medicaid patients undergoing lumbar elective lumbar spine surgery were using opioids preoperatively and continued long-term use postoperatively at a higher rate than previously reported databases. Preoperative and perioperative intake, degenerative disk disease, multiple prescribers, depression, and concomitant medications were significant risk factors.

Surgical prescription opioid trajectories among state Medicaid enrollees.

OBJECTIVE: The objective of this study was to evaluate opioid use trajectories among a sample of 10,138 Medicaid patients receiving one of six index surgeries: lumbar spine, total knee arthroplasty, cholecystectomy, appendectomy, colon resection, and tonsillectomy. DESIGN: Retrospective cohort. SETTING: Administrative claims data. PATIENTS AND PARTICIPANTS: Patients, aged 13 years and older, with 15-month continuous Medicaid eligibility surrounding index surgery, were selected from single-state Medicaid medical and pharmacy claims data for surgeries performed between 2014 and 2017. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Baseline comorbidities and presurgery opioid use were assessed in the 6 months prior to admission, and patients' opioid use was followed for 9 months post-discharge. Generalized linear model with log link and Poisson distribution was used to determine risk of chronic opioid use for all risk factors. Group-based trajectory models identified groups of patients with similar opioid use trajectories over the 15-month study period. RESULTS: More than one in three (37.7 percent) patients were post-surgery chronic opioid users, defined as the dichotomous outcome of filling an opioid prescription 90 or more days after surgery. Key variables associated with chronic post-surgery opioid use include presurgery opioid use, 30-day post-surgery opioid use, and comorbidities. Latent trajectory modeling grouped patients into six distinct opioid use trajectories. Associates of trajectory group membership are reported. CONCLUSIONS: Findings support the importance of surgeons setting realistic patient expectations for post-surgical opioid use, as well as the importance of coordination of post-surgical care among patients failing to fully taper off opioids within 1-3 months of surgery.

Towards cataloguing and characterising advance care planning and end-of-life care resources.

BACKGROUND: Resources for healthcare professionals, patients and those important to them relating to planning and coordinating treatment and care at the end of life are abundant, and can be difficult to navigate. However, they have not been systematically collated or catalogued in terms of their purpose, scope or intended audience. AIM: To collate, categorise and characterise advance care planning and end-of-life treatment and care (EoLT + C) resources directed towards healthcare professionals, patients and their families. METHODS: Rapid review and thematic synthesis of resources available in the United Kingdom. Google searches and reviews of websites belonging to selected organisations that develop and publish materials relating to EoLT + C, and advance care planning were used. Materials were included if they were intended for those over 18 living in the UK and pertained to five domains of EoLT + C: identifying those approaching end of life; accessing EoLT + C services; conducting important conversations about EoLT + C and preferences; advance care planning, including recording of preferences and plans; and ensuring that plans and preferences are accessed and used by health and social care services. RESULTS: 246 resources directed at healthcare professionals, patients and their families were identified, collated, catalogued and made internationally available for clinicians, researchers, patients and the public. 61 were classified as interactive, providing decision support in EoLT + C that went beyond simply providing information. Of these, there was notable content overlap among tools for identifying patients in their last year of life. There was variation in the development of tools across all domains of end-of-life care by geography and patient group. Few interactive resources integrated seamlessly with a digital interface or healthcare provider workflows. Incentives for the adoption of best-practice appeared rare. CONCLUSIONS: We present a repeatable and scalable approach to the cataloguing and characterisation of palliative care resources. The identified resources will be of benefit not only to those in the UK but to those in other countries, developing or evaluating their own resources for aiding professionals and patients to plan and deliver excellent treatment and care at the end of life.

Incidence and patterns of persistent opioid use in children following appendectomy.

BACKGROUND: The past 5 years have witnessed a concerted national effort to assuage the rising tide of the opioid misuse in our country. Surgical procedures often serve as the initial exposure of children to opioids, however the trajectory of use following these exposures remains unclear. We hypothesized that opioid exposure following appendectomy would increase the risk of persistent opioid use among publicly insured children. STUDY DESIGN: A retrospective longitudinal cohort study was conducted on South Carolina Medicaid enrollees who underwent appendectomy between January 2014 and December 2017 using administrative claims data. The primary outcome was chronic opioid use. Generalized linear models and finite mixture models were employed in analysis. RESULTS: 1789 Medicaid pediatric patients underwent appendectomy and met inclusion criteria. The mean age was 11.1 years and 40.6% were female. Most patients (94.6%) did not receive opioids prior to surgery. Opioid prescribing ≥90 days after surgery (chronic opioid use) occurred in 127 (7.1%) patients, of which 102 (80.3%) had no opioid use in the preexposure period. Risk factors for chronic opioid use included non-naïve opioid status, re-hospitalization more than 30 days following surgery, multiple opioid prescribers, age, and multiple antidepressants/antipsychotic prescriptions. Group-based trajectory analysis demonstrated four distinct post-surgical opioid use patterns: no opioid use (91.3%), later use (6.7%), slow wean (1.9%), and higher use throughout (0.4%). CONCLUSION: Opioid exposure after appendectomy may serve as a priming event for persistent opioid use in some children. Eighty percent of children who developed post-surgical persistent opioid use had not received opioids in the 90 days leading up to surgery. Several mutable and immutable factors were identified to target future efforts toward opioid minimization in this at-risk patient population. LEVEL OF EVIDENCE: III.

New chronic opioid use in Medicaid patients following cholecystectomy.

Background: Commercial insurance data show that chronic opioid use in opioid-naive patients occurs in 1.5% to 8% of patients undergoing surgical procedures, but little is known about patients with Medicaid. Methods: Opioid prescription data and medical coding data from 4,788 Medicaid patients who underwent cholecystectomy were analyzed to determine opioid use patterns. Results: A total of 54.4% of patients received opioids prior to surgery, and 38.8% continued to fill opioid prescriptions chronically; 27.1% of opioid-naive patients continued to get opioids chronically. Patients who received ≥ 50 MME/d had nearly 8 times the odds of chronic opioid use. Each additional opioid prescription filled within 30 days was associated with increased odds of chronic use (odds ratio: 1.71). Conclusion: Opioid prescriptions are common prior to cholecystectomy in Medicaid patients, and 38.8% of patients continue to receive opioid prescriptions well after surgical recovery. Even 27.1% of opioid-naive patients continued to receive opioid prescriptions chronically.

Fostering collaborative learning and leadership through near-peer mentorship among undergraduate nursing students.

BACKGROUND: Innovative teaching strategies in nursing education are essential with increasing enrollment. Collaborative learning and leadership (CLL) activities encourage near-peer learning through mentorship between senior-level and novice students while supporting teaching ratios in lab and clinical. In this study, senior nursing students' perceptions and performance during CLL activities were explored. METHODS: Final-semester senior students participated in CLL activities and were evaluated on their leadership and engagement. Grading rubric results were summarized using descriptive statistics. Thematic analysis of students' post-CLL reflections supported common themes. RESULTS: Students' average scores (97.53%) confirm students were prepared and engaged in CLL activities. Senior students enjoyed "building confidence" through these activities, with a consistent theme of "becoming a leader," noted in reflections. CONCLUSION: Near-peer learning activities assisted senior students in development of leadership and communication skills, preparing them for nursing practice. Recommendations include developing instructions for varied CLL activities and exploring faculty perspectives regarding this experience.

Risk factors and trajectories of opioid use following total knee replacement.

BACKGROUND: Opioids are commonly used to manage orthopedic pain in those undergoing total knee arthroplasty (TKA). There are limited studies assessing patterns of perioperative opioid use and risk factors for chronic use in patients undergoing TKA. METHODS: This is a retrospective longitudinal cohort study of Medicaid enrollees undergoing TKA between 2014 and 2017 using de-identified medical and pharmacy claims. The primary outcome was chronic opioid use (opioid prescription filled 90-270 days following TKA). Trajectory group membership was determined by identifying distinct groups of patients with similar patterns of daily morphine milligram equivalent (MME) values during the postsurgery follow-up period. RESULTS: In total, 1666 TKA surgeries performed in 1507 patients were included; 69% of patients were classified as chronic opioid users. Multivariable analyses identified prior opioid use, high opioid doses during the month after TKA, concomitant mood therapies and benzodiazepines, and comorbid conditions as important risk factors. Group-based trajectory analysis identified five distinct post-TKA surgery opioid use phenotypes with several key characteristics predicting group membership. CONCLUSIONS: This large-scale analysis demonstrated that chronic opioid use was common after TKA surgery and established several important risk factors for chronic use following TKA. Novel analysis revealed five distinct opioid use trajectories and identified key characteristics to help guide clinicians when determining perioperative opioid use. Results demonstrate that interventional studies attempting to reduce opioids after TKA are needed if reductions in long-term use are to be realized in this high-risk patient population.

Effectiveness of Homologous and Heterologous COVID-19 Booster Doses Following 1 Ad.26.COV2.S (Janssen [Johnson & Johnson]) Vaccine Dose Against COVID-19-Associated Emergency Department and Urgent Care Encounters and Hospitalizations Among Adults - VISION Network, 10 States, December 2021-March 2022.

CDC recommends that all persons aged ≥18 years receive a single COVID-19 vaccine booster dose ≥2 months after receipt of an Ad.26.COV2.S (Janssen [Johnson & Johnson]) adenovirus vector-based primary series vaccine; a heterologous COVID-19 mRNA vaccine is preferred over a homologous (matching) Janssen vaccine for booster vaccination. This recommendation was made in light of the risks for rare but serious adverse events following receipt of a Janssen vaccine, including thrombosis with thrombocytopenia syndrome and Guillain-Barré syndrome† (1), and clinical trial data indicating similar or higher neutralizing antibody response following heterologous boosting compared with homologous boosting (2). Data on real-world vaccine effectiveness (VE) of different booster strategies following a primary Janssen vaccine dose are limited, particularly during the period of Omicron variant predominance. The VISION Network§ determined real-world VE of 1 Janssen vaccine dose and 2 alternative booster dose strategies: 1) a homologous booster (i.e., 2 Janssen doses) and 2) a heterologous mRNA booster (i.e., 1 Janssen dose/1 mRNA dose). In addition, VE of these booster strategies was compared with VE of a homologous booster following mRNA primary series vaccination (i.e., 3 mRNA doses). The study examined 80,287 emergency department/urgent care (ED/UC) visits¶ and 25,244 hospitalizations across 10 states during December 16, 2021-March 7, 2022, when Omicron was the predominant circulating variant.** VE against laboratory-confirmed COVID-19-associated ED/UC encounters was 24% after 1 Janssen dose, 54% after 2 Janssen doses, 79% after 1 Janssen/1 mRNA dose, and 83% after 3 mRNA doses. VE for the same vaccination strategies against laboratory-confirmed COVID-19-associated hospitalizations were 31%, 67%, 78%, and 90%, respectively. All booster strategies provided higher protection than a single Janssen dose against ED/UC visits and hospitalizations during Omicron variant predominance. Vaccination with 1 Janssen/1 mRNA dose provided higher protection than did 2 Janssen doses against COVID-19-associated ED/UC visits and was comparable to protection provided by 3 mRNA doses during the first 120 days after a booster dose. However, 3 mRNA doses provided higher protection against COVID-19-associated hospitalizations than did other booster strategies during the same time interval since booster dose. All adults who have received mRNA vaccines for their COVID-19 primary series vaccination should receive an mRNA booster dose when eligible. Adults who received a primary Janssen vaccine dose should preferentially receive a heterologous mRNA vaccine booster dose ≥2 months later, or a homologous Janssen vaccine booster dose if mRNA vaccine is contraindicated or unavailable. Further investigation of the durability of protection afforded by different booster strategies is warranted.

Dietary Intakes of Children Enrolled in US Early Child-Care Programs During Child-Care and Non-Child-Care Days.

BACKGROUND: Early-child-care (ECE) programs may substantially influence child diet quality. OBJECTIVE: The Study of Nutrition and Activity in Child Care Settings describes the usual food group intake of preschool-aged children attending ECE programs relative to Dietary Guidelines for Americans (DGA) recommendations, comparing intakes during child-care and non-child-care days. DESIGN: Meal observations and parent-completed food diaries in a cross-sectional nationally representative multistage cluster sample of Child and Adult Care Food Program-participating ECE programs. PARTICIPANTS/SETTING: One thousand four hundred sixty-eight children aged 3 to 5 years attending 217 Child and Adult Care Food Program-participating ECE programs (eg, child-care centers and Head Start) during 2017. MAIN OUTCOME MEASURES: Daily energy intake, daily US Department of Agriculture Food Pattern Food Group intakes, and percentage of daily intakes meeting 2015-2020 DGA Food Pattern recommendations. STATISTICAL ANALYSES PERFORMED: Regression-adjusted usual intakes and percentage of children meeting recommendations were estimated using the National Cancer Institute method. Single-day mean intakes were used to test for statistical differences between child-care and non-child-care days. RESULTS: Mean usual energy intake was 1,524 ± 19.3 kcal during child-care days and exceeded the recommended range at 1,702 ± 30.2 kcal during non-child-care days; single-day means indicated significantly lower energy intake on child-care days (P < 0.001). The percent of children meeting DGA recommendations on a child-care day varied by DGA food group: fruits (51.4%), grains (50.1%), dairy (42.5%), vegetables (6.5%), whole grains (4.6%), and protein foods (0.1%). Recommended limits on calories from added sugar and solid fats were met by 28.2% and 14.6% of children, respectively. Compared with mean food group intakes during a single child-care day, non-child-care day intakes were similar for fruits and vegetables, lower for dairy and whole grains, and higher for total grains, protein foods, and calories from added sugars and solid fats. CONCLUSIONS: Although there is room to increase nutrient density inside and outside of child care, intakes on child-care days more closely align to DGAs.

Patterns of dispensed opioids after tonsillectomy in children and adolescents in South Carolina, United States, 2010-2017.

OBJECTIVES: Tonsillectomy (with or without adenoidectomy) is a common pediatric surgical procedure requiring post-operative analgesia. Because of the respiratory depression effects of opioids, clinicians strive to limit the use of these drugs for analgesia post-tonsillectomy. The objective of this study was to identify demographic and medication use patterns predictive of persistent opioid dispensing (as a proxy for opioid use) to pediatric patients post-tonsillectomy. PATIENTS AND METHODS: Retrospective cohort of South Carolina (USA) Medicaid-insured children and adolescents 0-18 years old without malignancy who had tonsillectomy in 2014-2017. We evaluated opioid dispensing pre-surgery and in the 30 days exposure period after hospital discharge. The main outcome, persistent opioid dispensing, was defined as any subject dispensed ≥1 opioid prescription 90-270 days after discharge. Group-based trajectory analyses described post-procedure opioid dispensing trajectories. RESULTS: There were 11,578 subjects representing 12,063 tonsillectomy procedures. Few (3.5%) procedures were followed by persistent opioid dispensing. Any opioid dispensing during the exposure period was associated with an increased odds of persistent opioid dispensing status during the follow up period (OR 1.51 for 1-6 days of exposure and OR 1.65 for 7-30 days of opioid exposure), as was pre-procedure opioid dispensing, having >1 tonsillectomy procedure, and having complex chronic medical conditions. Group-based trajectory analyses identified 4 distinct patterns of post-discharge opioid dispensing. CONCLUSIONS: Any opioid dispensing during the 30 days after tonsillectomy increased the odds of persistent opioid dispensing by > 50%. Multivariable and group-based trajectory analyses identified patient and procedure variables that correlate with persistent opioid dispensing, primarily driven by groups receiving pre-tonsillectomy opioids and a second group who experienced multiple episodes of tonsillectomy.

Hydrophobin Rodlets on the Fungal Cell Wall.

The conidia of airborne fungi are protected by a hydrophobic protein layer that coats the cell wall polysaccharides and renders the spores resistant to wetting and desiccation. A similar layer is presented on the outer surface of the aerial hyphae of some fungi. This layer serves multiple purposes, including facilitating spore dispersal, mediating the growth of hyphae into the air from moist environments, aiding host interactions in symbiotic relationships and increasing infectivity in pathogenic fungi. The layer consists of tightly packed, fibrillar structures termed "rodlets", which are approximately 10 nm in diameter, hundreds of nanometres long and grouped in fascicles. Rodlets are an extremely stable protein structure, being resistant to detergents, denaturants and alcohols and requiring strong acids for depolymerisation. They are produced through the self-assembly of small, surface-active proteins that belong to the hydrophobin protein family. These small proteins are expressed by all filamentous fungi and are characterised by a high proportion of hydrophobic residues and the presence of eight cysteine residues. Rodlets are a form of the functional amyloid fibril, where the hydrophobin monomers are held together in the rodlets by intermolecular hydrogen bonds that contribute to a stable ß-sheet core.

Clinicians' and Pharmacists' Reported Implementation of Vaccination Practices for Adults.

INTRODUCTION: Despite the proven effectiveness of immunization in preventing morbidity and mortality, adult vaccines remain underutilized. The objective of this study was to describe clinicians' and pharmacists' self-reported implementation of the Standards for Adult Immunization Practice ("the Standards"; i.e., routine assessment, recommendation, and administration/referral for needed vaccines, and documentation of administered vaccines, including in immunization information systems). METHODS: Two Internet panel surveys (one among clinicians and one among pharmacists) were conducted during February-March 2017 and asked respondents about their practice's implementation of the Standards. T-tests assessed associations between clinician medical specialty, vaccine type, and each component of the Standards (March-August 2017). RESULTS: Implementation of the Standards varied substantially by vaccine and provider type. For example, >80.0% of providers, including obstetrician/gynecologists and subspecialists, assessed for and recommended influenza vaccine. However, 24.3% of obstetrician/gynecologists and 48.9% of subspecialists did not stock influenza vaccine for administration. Although zoster vaccine was recommended by >89.0% of primary care providers, <58.0% stocked the vaccine; by contrast, 91.6% of pharmacists stocked zoster vaccine. Vaccine needs assessments, recommendations, and stocking/referrals also varied by provider type for pneumococcal; tetanus, diphtheria, acellular pertussis; tetanus diphtheria; human papillomavirus; and hepatitis B vaccines. CONCLUSIONS: This report highlights gaps in access to vaccines recommended for adults across the spectrum of provider specialties. Greater implementation of the Standards by all providers could improve adult vaccination rates in the U.S. by reducing missed opportunities to recommend vaccinations and either vaccinate or refer patients to vaccine providers.

Qualitative study of patient views on a 'telephone-first' approach in general practice in England: speaking to the GP by telephone before making face-to-face appointments.

OBJECTIVE: To understand patients' views on a 'telephone-first' approach, in which all appointment requests in general practice are followed by a telephone call from the general practitioner (GP). DESIGN: Qualitative interviews with patients and carers. SETTING: Twelve general practices in England. PARTICIPANTS: 43 patients, including 30 women, nine aged over 75 years, four parents of young children, five carers, five patients with hearing impairment and two whose first language was not English. RESULTS: Patients expressed varied views, often strongly held, ranging from enthusiasm for to hostility towards the 'telephone-first' approach. The new system suited some patients, avoiding the need to come into the surgery but was problematic for others, for example, when it was difficult for someone working in an open plan office to take a call-back. A substantial proportion of negative comments were about the operation of the scheme itself rather than the principles behind it, for example, difficulty getting through on the phone or being unable to schedule when the GP would phone back. Some practices were able to operate the scheme in a way that met their patients' needs better than others and practices varied significantly in how they had implemented the approach. CONCLUSIONS: The 'telephone-first' approach appears to work well for some patients, but others find it much less acceptable. Some of the reported problems related to how the approach had been implemented rather than the 'telephone-first' approach in principle and suggests there may be potential for some of the challenges experienced by patients to be overcome.

Opioid Prescription Drug Use and Expenditures in US Outpatient Physician Offices: Evidence from Two Nationally Representative Surveys.

BACKGROUND: Opioids are widely prescribed for their analgesic properties. Chronic opioid use is a persistent problem in the US. Nevertheless, little is known about its prescribing and utilization patterns and overall expenditures. OBJECTIVE: This study examined secular trends in opioid prescription drug utilization and expenditures, along with factors associated with opioid prescription drug use in US physician offices. METHODS: National Ambulatory Medical Care Survey (NAMCS) and Medical Expenditure Panel Survey (MEPS) data (2006-2010), both nationally representative surveys, were used to assess the trend, predictors of opioid prescription among US adults (more than 18 years) and the opioid-associated expenditures as a whole and borne by the patients in outpatient settings. RESULTS: Opioid prescription drugs use among US adults in outpatient settings, as a percentage of all prescription drugs, showed a gradual increase since 2006, leveling off in 2010. Opioid prescription drug expenditures showed an upward trend from 2009 after declining over three years. Mean out-of-pocket payments per prescription steadily declined over study period. LIMITATIONS: Cross-sectional nature and visit based information of NAMCS do not provide the actual prevalence and the reason for opioid prescription. CONCLUSIONS: Given the upward trend in opioid prescription drug utilization and associated expenditures, clinicians may benefit from evidence-based methods of monitoring prescription opioid use to prevent misuse, abuse, and other adverse patient outcomes. FUNDING: Drs. Qureshi, Haider, Ball, Horner and Bennett's efforts are partially supported by the University of South Carolina's ASPIRE I. Dr. Wooten's effort is funded by the National Institute on Drug Abuse (K01DA037412).

The use and impact of quality of life assessment tools in clinical care settings for cancer patients, with a particular emphasis on brain cancer: insights from a systematic review and stakeholder consultations.

PURPOSE: Patient-reported data are playing an increasing role in health care. In oncology, data from quality of life (QoL) assessment tools may be particularly important for those with limited survival prospects, where treatments aim to prolong survival while maintaining or improving QoL. This paper examines the use and impact of using QoL measures on health care of cancer patients within a clinical setting, particularly those with brain cancer. It also examines facilitators and challenges, and provides implications for policy and practice. DESIGN: We conducted a systematic literature review, 15 expert interviews and a consultation at an international summit. RESULTS: The systematic review found no relevant intervention studies specifically in brain cancer patients, and after expanding our search to include other cancers, 15 relevant studies were identified. The evidence on the effectiveness of using QoL tools was inconsistent for patient management, but somewhat more consistent in favour of improving patient-physician communication. Interviews identified unharnessed potential and growing interest in QoL tool use and associated challenges to address. CONCLUSION: Our findings suggest that the use of QoL tools in cancer patients may improve patient-physician communication and have the potential to improve care, but the tools are not currently widely used in clinical practice (in brain cancer nor some other cancer contexts) although they are in clinical trials. There is a need for further research and stakeholder engagement on how QoL tools can achieve most impact across cancer and patient contexts. There is also a need for policy, health professional, research and patient communities to strengthen information exchange and debate, support awareness raising and provide training on tool design, use and interpretation.

The association between influenza vaccination and other preventative health behaviors in a cohort of pregnant women.

OBJECTIVES: Although pregnant women are a high-priority group for seasonal influenza vaccination, vaccination rates in this population remain below target levels. Previous studies have identified sociodemographic predictors of vaccine choice, but relationships between preconception heath behaviors and seasonal influenza vaccination are poorly understood. This prospective cohort study followed pregnant women during the 2010-2011 influenza season to determine if certain health behaviors were associated with vaccination status. METHOD: Participants were pregnant women receiving prenatal care from Kaiser Permanente Northwest and Kaiser Permanente Northern California. Women were surveyed about preconception smoking, alcohol consumption, and vitamin/supplement use. Vaccination data were obtained from health plan databases and state immunization records. RESULTS: Data from 1,204 women were included in this analysis. Most participants (1,204; 66.4%) received a seasonal influenza vaccine during the study period. Women vaccinated prior to pregnancy were more likely to use a supplement containing folic acid (80%) or vitamin D (30%) compared with women who were vaccinated during pregnancy (72% and 15%, respectively) or unvaccinated women (62% and 12%, respectively, p < .001). Women vaccinated prior to or during pregnancy were more likely (75%) to have never smoked compared with women who were not vaccinated (70%, p = .005). There were no significant differences in alcohol use or household cigarette smoke exposure by vaccination group. CONCLUSIONS: Women who engaged in specific preconception health behaviors were more likely to receive seasonal influenza vaccination. Failure to participate in these health behaviors could alert health care practitioners to patients' increased risk of remaining unvaccinated during pregnancy.

Subjective social status predicts wintertime febrile acute respiratory illness among women healthcare personnel.

OBJECTIVE: We ask whether subjective social status (SSS) predicts rates of wintertime febrile acute respiratory illness (ARI). METHODS: 1,373 women and 346 men were enrolled from September 1 through November 30, 2010 as part of a prospective cohort study of health care personnel (HCP) at two medical centers. A questionnaire was completed at enrollment followed by 20 weeks of surveillance. ARI was an illness with fever and cough self-reported via weekly telephone or Internet-based surveillance. RESULTS: For both sexes, lower SSS was associated with younger age, less education, lower neighborhood household income, being unmarried, lower occupational status, working in outpatient settings, and poorer self-rated health status. Demographic and occupational covariates explained 23% and 42% of the variance (R²) in SSS among women and men, respectively. Smoking, exercise frequency, and sleep quality were also associated with SSS, but these factors explained little additional variance (3-4%). Among women HCP, lower SSS at enrollment was associated with higher rates of subsequent ARI (unadjusted ß = -.21 [±.05], p < .001 for ordinal data). Adjusting for all covariates reduced the effect size of the SSS minimally (adjusted ß = -.19 [±.06], p < .001). Among men HCP, there was no univariate SSS-ARI association and after adjusting for all covariates the effect was opposite of our hypothesis (adjusted ß = .33 [±.17], p < .05). CONCLUSIONS: Women (but not men) with lower SSS were more likely to report an ARI during surveillance, and the SSS-ARI association was independent of demographics, occupational status, health, and health behaviors.

Jails, HIV testing, and linkage to care services: an overview of the EnhanceLink initiative.

Over 9 million persons in the United States (US) are admitted each year to jails. HIV prevalence among detainees is higher than the general population, which creates a public health need for linking HIV-infected detainees to services during jail and after release. The EnhanceLink initiative was funded as demonstration projects in 10 communities at 20 separate jails across the US. Grantees implemented and evaluated innovative models of HIV testing in jails and linkage of HIV-infected individuals to community services post release. In this paper, we describe services delivered with the EnhanceLink initiative. During 877,119 admission events, 210,267 inmates agreed to HIV testing and 822 new diagnoses of HIV were made. The majority of persons served with transitional services were previously diagnosed before the current incarceration. Cumulatively, 9,837 HIV+ persons were offered linkage and transitional services and 8,056 (82 %) accepted the offer. EnhanceLink demonstrated the feasibility of HIV testing in jail settings and provision of linkage services to enhance continuity of HIV care post-release.

Early identification of HIV: empirical support for jail-based screening.

BACKGROUND: Although routine HIV testing is recommended for jails, little empirical data exist describing newly diagnosed individuals in this setting. METHODS: Client-level data (CLD) are available on a subset of individuals served in EnhanceLink, for the nine of the 10 sites who enrolled newly diagnosed persons in the client level evaluation. In addition to information about time of diagnosis, we analyzed data on initial CD4 count, use of antiretroviral therapy (ART), and linkage to care post discharge. Baseline data from newly diagnosed persons were compared to data from persons whose diagnoses predated jail admission. RESULTS: CLD were available for 58 newly diagnosed and 708 previously diagnosed individuals enrolled between 9/08 and 3/11. Those newly diagnosed had a significantly younger median age (34 years) when compared to those previously diagnosed (41 years). In the 30 days prior to incarceration, 11% of those newly diagnosed reported injection drug use and 29% reported unprotected anal intercourse. Median CD4 count at diagnosis was 432 cells/mL (range: 22-1,453 cells/mL). A minority (21%, N = 12) of new diagnoses started antiretroviral treatment (ART) before release; 74% have evidence of linkage to community services. CONCLUSION: Preliminary results from a cross-sectional analysis of this cohort suggest testing in jails finds individuals early on in disease progression. Most HIV(+) detainees did not start ART in jail; therefore screening may not increase pharmacy costs for jails. Detainees newly diagnosed with HIV in jails can be effectively linked to community resources. Jail-based HIV testing should be a cornerstone of "test and treat" strategies.

Diamond Blackfan anemia.

Mutations affecting genes encoding ribosomal proteins cause Diamond Blackfan anemia (DBA), a rare congenital syndrome associated with physical anomalies, short stature, red cell aplasia, and an increased risk of malignancy. p53 activation has been identified as a key component in the pathophysiology of DBA after cellular and molecular studies of knockdown cellular and animal models of DBA and other disorders affecting ribosomal assembly or function. Other potential mechanisms that warrant further investigation include impaired translation as the result of ribosomal insufficiency, which may be ameliorated by leucine supplementation, and alternative splicing leading to reduced expression of a cytoplasmic heme exporter, the human homolog of the receptor for feline leukemia virus C (FVLCR). However, the molecular basis for the characteristic steroid responsiveness of the erythroid failure in DBA remains unknown. This review explores the clinical and therapeutic implications of the current state of knowledge and delineates important but as-yet-unanswered questions.
