Ubiquinone deficiency drives reverse electron transport to disrupt hepatic metabolic homeostasis in obesity.

Mitochondrial reactive oxygen species (mROS) are central to physiology. While excess mROS production has been associated with several disease states, its precise sources, regulation, and mechanism of generation in vivo remain unknown, limiting translational efforts. Here we show that in obesity, hepatic ubiquinone (Q) synthesis is impaired, which raises the QH 2 /Q ratio, driving excessive mROS production via reverse electron transport (RET) from site I Q in complex I. Using multiple complementary genetic and pharmacological models in vivo we demonstrated that RET is critical for metabolic health. In patients with steatosis, the hepatic Q biosynthetic program is also suppressed, and the QH 2 /Q ratio positively correlates with disease severity. Our data identify a highly selective mechanism for pathological mROS production in obesity, which can be targeted to protect metabolic homeostasis.

Biosynthesis of 6- and 7-Mono-Demethylated Nobiletins by a Newly Isolated Strain of Yeast.

Demethylated nobiletins (DMNs), which are generally recognized as the metabolites of orally administered nobiletin, are widely investigated. However, studies related to 8-demethylated-nobiletin, 7-demethylated-nobiletin (7DMN), and 6-demethylated-nobiletin (6DMN) are limited due to the lack of a synthesis method. In this study, a strain of microbe able to metabolize nobiletin was isolated from aged orange peel. Internal transcribed spacers (ITS) rRNA sequencing analysis showed it belonged to the yeast family, Filobasidium magnum specie. High-performance liquid chromatography (HPLC), HPLC-MS, and 13C NMR results proved that the metabolites were 7DMN and 6DMN. Growth curves of the isolated yeast were studied at different temperatures, media pH, NaCl, and glucose concentrations. Meanwhile, factors that influence the demethylation efficiencies were also investigated. This study lays the groundwork for the investigation of the biological functions of these two compounds and opens a new window for further research of the metabolic fate of nobiletin in the human body.

Anterior Insular-nucleus Accumbens Pathway Controls Refeeding-induced Analgesia under Chronic Inflammatory Pain Condition.

Feeding behaviors are closely associated with chronic pain in adult rodents. Our recent study revealed that 2 h refeeding after 24 h fasting (i.e., refeeding) attenuates pain behavior under chronic inflammatory pain conditions. However, while brain circuits mediating fasting-induced analgesia have been identified, the underlying mechanism of refeeding-induced analgesia is still elusive. Herein, we demonstrate that the neural activities in the nucleus accumbens shell (NAcS) and anterior insular cortex (aIC) were increased in a modified Complete Freund's Adjuvant (CFA)-induced chronic inflammatory pain condition, which was reversed by refeeding. We also found that refeeding reduced the enhanced excitability of aICCaMKII-NAcSD2R projecting neurons in this CFA model. Besides, chemogenetic inhibition of aICCaMKII-NAcSD2R neural circuit suppressed chronic pain behavior while activation of this circuit reversed refeeding-induced analgesia. Thus, the present study suggests that aICCaMKII-NAcSD2R neural circuit mediates refeeding-induced analgesia, thereby serving as a potential therapeutic target to manage chronic pain.

Effects of traditional Cantonese opera songs on Cantonese-speaking, community-dwelling older adults' cognitive and psychological function, well-being, and health.

Objectives: Experiencing multi-sensory cognitive stimulation through the enjoyment of Cantonese opera songs, with their lively rhythms, familiar folk tales, meaningful lyrics and pleasant scenarios, has the potential to increase neuroplasticity and prevent cognitive decline.Methods: This prospective pre- and post-test quasi-experimental randomised controlled trial design study aimed to explore the social benefits of older adults' active participation in practising Cantonese opera songs as compared with passive participation (as an audience) and a non-interventional control group on cognitive function psychological function, functional independence, well-being and health.Results: By recruiting a group of older adults who were receiving day activities social service in Hong Kong. Thirty participants were randomly allocated to active participation in Cantonese opera (ACO). They participated in practising Cantonese opera songs. Thirty-four participants were assigned to passive participation in Cantonese opera (PCO). They received passive intervention by listening to and appreciating the opera songs as a social event. Thirty-one participants were used as a control group and received no similar training. (Results) ACO caused a positive change in cognitive function as compared to PCO and to no intervention, which implies that active learning and practise of opera songs benefits global cognitive function. The psychological function of the participants in the PCO group showed an elevated positive affect and a reduced negative affect. A statistically significant difference was noted in the time effect among the physical domains of health status, functional independence and well-being of participants who underwent Cantonese opera intervention.

Patterns of brain c-Fos expression in response to feeding behavior in acute and chronic inflammatory pain condition.

OBJECTIVES: Feeding behavior is known to have potential to alleviate pain. We recently demonstrated that both 24 h fasting and 2 h refeeding (food intake after 24 h fasting) induce analgesia in inflammatory pain conditions via different brain mechanisms. However, brain structures that distinctly involved fasting- and refeeding-induced analgesia is still unknown. Hence, this study is aimed to reveal brain structures mediating fasting- and refeeding-induced analgesia. METHODS: Mice were given intraplantar (i.pl.) injection of formalin and complete Freund's adjuvant into the left hind paw to induce acute and chronic inflammatory pain, respectively. We examined changes in c-Fos expression with 24 h fasting and 2 h refeeding under acute and chronic inflammatory pain conditions in the contralateral brain. RESULTS: Under acute pain condition, c-Fos expression changed with fasting in the anterior cingulate cortex (ACC), central amygdala (CeA), lateral hypothalamus (LH) and nucleus accumbens core (NAcC). Refeeding changed c-Fos expression in the CeA, LH and lateral parabrachial nucleus (lPBN). On the other hand, under chronic inflammatory pain condition, c-Fos expression changed with fasting in the lPBN, medial prefrontal cortex (mPFC) and nucleus accumbens shell (NAcS) while refeeding changed c-Fos expression in the anterior insular cortex, lPBN, mPFC and NAcS. CONCLUSION: The present results show that brain regions that participated in the fasting- and refeeding-induced analgesia were completely different in acute and chronic inflammatory pain conditions. Also, refeeding recruits more brain regions under chronic inflammatory pain conditions compared to the acute inflammatory pain condition. Collectively, our findings provide novel insights into brain regions involved in fasting- and refeeding-induced analgesia, which can be potential neural circuit-based targets for the development of novel therapeutics.

Testimony and meaning: A qualitative study of Black women with cancer diagnoses.

OBJECTIVE: Research has established religion and spirituality as important resources for Black people in the U.S. coping with adversity. Most research has been from an etic perspective, examining religious variables that are valid across multiple religions. In the present study, we asked what emic aspects of the Black church's practices and theological emphases women with cancer drew on in constructing meaning-making narratives from their cancer experience. METHOD: In this consensual qualitative research study, we interviewed 30 Black women with cancer histories with an average age of 64.5. RESULTS: The religious practice of testimony emerged as the predominant theme. Testimony (a) provided a meaningful purpose to the cancer experience; (b) had a specific content of describing what God had done in their lives as well as some common theological emphases; (c) had dual desired outcomes of helping others and bringing glory to God; and (d) had an associated practice of giving testimony. CONCLUSION: We discuss testimony as a narrative structure and highlight its importance in informing culturally sensitive interventions aimed at supporting Black women with cancer.

Implementing a digital health model of care in Australian youth mental health services: protocol for impact evaluation.

BACKGROUND: The World Economic Forum has recently highlighted substantial problems in mental health service provision and called for the rapid deployment of smarter, digitally-enhanced health services as a means to facilitate effective care coordination and address issues of demand. In mental health, the biggest enabler of digital solutions is the implementation of an effective model of care that is facilitated by integrated health information technologies (HITs); the latter ensuring the solution is easily accessible, scalable and sustainable. The University of Sydney's Brain and Mind Centre (BMC) has developed an innovative digital health solution - delivered through the Youth Mental Health and Technology Program - which incorporates two components: 1) a highly personalised and measurement-based (data-driven) model of youth mental health care; and 2) an industrial grade HIT registered on the Australian Register of Therapeutic Goods. This paper describes a research protocol to evaluate the impact of implementing the BMC's digital health solution into youth mental health services (i.e. headspace - a highly accessible, youth-friendly integrated service that responds to the mental health, physical health, alcohol or other substance use, and vocational concerns of young people aged 12 to 25 years) within urban and regional areas of Australia. METHODS: The digital health solution will be implemented into participating headspace centres using a naturalistic research design. Quantitative and qualitative data will be collected from headspace health professionals, service managers and administrators, as well as from lead agency and local Primary Health Network (PHN) staff, via service audits, Implementation Officer logs, online surveys, and semi-structured interviews, at baseline and then three-monthly intervals over the course of 12 months. DISCUSSION: At the time of publication, six headspace centres had been recruited to this study and had commenced implementation and impact evaluation. The first results are expected to be submitted for publication in 2021. This study will focus on the impact of implementing a digital health solution at both a service and staff level, and will evaluate digital readiness of service and staff adoption; quality, usability and acceptability of the solution by staff; staff self-reported clinical competency; overall impact on headspace centres as well as their lead agencies and local PHNs; and social return on investment.

Childhood Trauma Predicts Cancer Treatment-Related Pain in Breast Cancer Survivors.

BACKGROUND: Childhood trauma has been linked to neuropathic pain in noncancer populations, but its relationship with cancer treatment-related neuropathic pain is unknown. OBJECTIVE: This secondary data analysis of a prospective, longitudinal, observational study aimed to explore the relationship of childhood trauma experience with pain severity, pain interference, and neuropathic symptom severity (NSS) 12 months after surgery in women receiving treatment for stage 0 to III breast cancer. METHODS: Women (N = 44) recruited from a comprehensive cancer center self-reported childhood trauma experience, pain severity, pain interference, NSS, co-occurring symptoms, and pain beliefs via questionnaires. Descriptive statistics were used to describe childhood trauma experience. Linear regression was used to model childhood trauma and other predictors on pain variables 12 months after surgery. RESULTS: Childhood trauma predicted pain severity and pain interference 12 months after surgery (P < .05), as did baseline pain severities and helplessness-pain catastrophizing. Age predicted only NSS. Together, the best models predicted 31.6% to 40.9% of the variance in pain severities at 12 months (P < .001). CONCLUSIONS: Childhood trauma exposure was a significant predictor of pain 12 months after breast cancer surgery and adjuvant treatment. Younger and helplessness-pain catastrophizing women are also at risk. Research is needed to identify preventive neuropathic pain interventions for high-risk women. IMPLICATIONS FOR PRACTICE: Women receiving breast cancer treatment should proactively be assessed for childhood trauma history, possibly by using discreet previsit questionnaires. Childhood trauma survivors may be at high risk for poor pain outcomes and may benefit from tailored pain interventions.

The analgesic effect of refeeding on acute and chronic inflammatory pain.

Pain is susceptible to various cognitive factors. Suppression of pain by hunger is well known, but the effect of food intake after fasting (i.e. refeeding) on pain remains unknown. In the present study, we examined whether inflammatory pain behavior is affected by 24 h fasting and 2 h refeeding. In formalin-induced acute inflammatory pain model, fasting suppressed pain behavior only in the second phase and the analgesic effect was also observed after refeeding. Furthermore, in Complete Freund's adjuvant-induced chronic inflammatory pain model, both fasting and refeeding reduced spontaneous pain response. Refeeding with non-calorie agar produced an analgesic effect. Besides, intraperitoneal (i.p.) administration of glucose after fasting, which mimics calorie recovery following refeeding, induced analgesic effect. Administration of opioid receptor antagonist (naloxone, i.p.) and cannabinoid receptor antagonist (SR 141716, i.p.) reversed fasting-induced analgesia, but did not affect refeeding-induced analgesia in acute inflammatory pain model. Taken together, our results show that refeeding produce analgesia in inflammatory pain condition, which is associated with eating behavior and calorie recovery effect.

Plant-Based Dietary Patterns, Plant Foods, and Age-Related Cognitive Decline.

The aging population is expanding, as is the prevalence of age-related cognitive decline (ARCD). Of the several risk factors that predict the onset and progression of ARCD, 2 important modifiable risk factors are diet and physical activity. Dietary patterns that emphasize plant foods can exert neuroprotective effects. In this comprehensive review, we examine studies in humans of plant-based dietary patterns and polyphenol-rich plant foods and their role in either preventing ARCD and/or improving cognitive function. As yet, there is no direct evidence to support the benefits of a vegetarian diet in preventing cognitive decline. However, there is emerging evidence for brain-health-promoting effects of several plant foods rich in polyphenols, anti-inflammatory dietary patterns, and plant-based dietary patterns such as the Mediterranean diet that include a variety of fruits, vegetables, legumes, nuts, and whole grains. The bioactive compounds present in these dietary patterns include antioxidant vitamins, polyphenols, other phytochemicals, and unsaturated fatty acids. In animal models these nutrients and non-nutrients have been shown to enhance neurogenesis, synaptic plasticity, and neuronal survival by reducing oxidative stress and neuroinflammation. In this review, we summarize the mounting evidence in favor of plant-centered dietary patterns, inclusive of polyphenol-rich foods for cognitive well-being. Randomized clinical trials support the role of plant foods (citrus fruits, grapes, berries, cocoa, nuts, green tea, and coffee) in improving specific domains of cognition, most notably frontal executive function. We also identify knowledge gaps and recommend future studies to identify whether plant-exclusive diets have an added cognitive advantage compared with plant-centered diets with fish and/or small amounts of animal foods.

Expectancy Effects on Self-Reported Attention-Deficit/Hyperactivity Disorder Symptoms in Simulated Neurofeedback: A Pilot Study.

OBJECTIVE: Expectancy is a psychological factor that can impact treatment effectiveness. Research on neurofeedback for attention-deficit/hyperactivity disorder (ADHD) suggests expectancy may contribute to treatment outcomes, though evidence for expectancy as an explanatory factor is sparse. This pilot study investigated the effects of expectancies on self-reported ADHD symptoms in simulated neurofeedback. METHOD: Forty-six adults who were concerned that they had ADHD expected to receive active neurofeedback, but were randomly assigned to receive a placebo with false feedback indicating attentive (positive false feedback) or inattentive (negative false feedback) states. Effects of the expectancy manipulation were measured on an ADHD self-report scale. RESULTS: Large expectancy effects were found, such that individuals who received positive false feedback reported significant decreases in ADHD symptoms, whereas individuals who received negative false feedback reported significant increases in ADHD symptoms. CONCLUSIONS: Findings suggest that expectancy should be considered as an explanatory mechanism for ADHD symptom change in response to neurofeedback.

Pressure Pain Phenotypes in Women Before Breast Cancer Treatment.

OBJECTIVES: To explore associations between quantitative sensory testing (QST) and pretreatment pain, physical, and psychological characteristics in women with breast cancer. SAMPLE & SETTING: 41 women with treatment-naive stage 0-III breast cancer at the University of Michigan Comprehensive Cancer Center in Ann Arbor. METHODS & VARIABLES: Participants completed self-report surveys and QST within the month before breast surgery. Pressure pain thresholds (PPTs) were measured bilaterally at each trapezius with a manual QST algometer. PPT values were split, yielding low, moderate, and high pain sensitivity subgroups. Subgroup self-reported characteristics were compared using Spearman's correlation, chi-square, and one-way analysis of variance. RESULTS: Lower PPT (higher sensitivity) was associated with higher levels of pain interference and maladaptive pain cognitions. The high-sensitivity group reported higher pain severities, interference, and catastrophizing and lower belief in internal locus of pain control than the low-sensitivity group. IMPLICATIONS FOR NURSING: Individualized interventions for maladaptive pain cognitions before surgery may reduce pain sensitivity and the severity of chronic pain developed after surgery.

Examining the Impact of a Web-Based Intervention to Promote Patient Activation in Chemotherapy-Induced Peripheral Neuropathy Assessment and Management.

Lack of activation in self-care can compromise a patient's ability to monitor and manage cancer treatment-related side effects, such as chemotherapy-induced peripheral neuropathy (CIPN). The web-based Carevive® Care Planning System (CPS) was developed to promote evidence-based symptom assessment and treatment by enhancing patients' involvement in their own care. The purpose of this single-arm, pre-test/post-test, prospective study was to examine whether the CPS can promote patient activation in CIPN symptom assessment and management. Seventy-five women with breast cancer receiving neurotoxic chemotherapy were recruited from a Comprehensive Cancer Center. Using standardized neuropathy measures embedded within the CPS, patients reported their CIPN symptoms over three consecutive clinical visits and completed the Patient Activation Measure (PAM) at the first and third visits. Mean changes in PAM scores between visits were compared using repeated measure analysis of covariance, adjusting for age. At baseline, patients were diagnosed with cancer within the past year (94.7%), highly activated (85% Level III/IV), and had a mean age of 51.3. PAM scores improved significantly from 67.15 (SD = 13.5; range = 47-100) at visit one to 69.29 (SD = 16.18; range = 47-100) (p = 0.02) (n = 62) at visit three. However, patients perceived the CPS to be of minimal value because it solely focused on CIPN and, for many, CIPN was not severe enough to motivate them to seek out symptom management information. Further research is needed to assess the utility of the CPS in promoting activation in the assessment and management of varying cancer treatment-related symptoms.

The safety of live attenuated influenza vaccine in children and adolescents 2 through 17 years of age: A Vaccine Safety Datalink study.

PURPOSE: To evaluate the safety of live attenuated influenza vaccine (LAIV) in children 2 through 17 years of age. METHODS: The study was conducted in 6 large integrated health care organizations participating in the Vaccine Safety Datalink (VSD). Trivalent LAIV safety was assessed in children who received LAIV between September 1, 2003 and March 31, 2013. Eighteen pre-specified adverse event groups were studied, including allergic, autoimmune, neurologic, respiratory, and infectious conditions. Incident rate ratios (IRRs) were calculated for each adverse event, using self-controlled case series analyses. For adverse events with a statistically significant increase in risk, or an IRR > 2.0 regardless of statistical significance, manual medical record review was performed to confirm case status. RESULTS: During the study period, 396 173 children received 590 018 doses of LAIV. For 13 adverse event groups, there was no significant increased risk of adverse events following LAIV. Five adverse event groups (anaphylaxis, syncope, Stevens-Johnson syndrome, adverse effect of drug, and respiratory failure) met criteria for manual medical record review. After review to confirm cases, 2 adverse event groups remained significantly associated with LAIV: anaphylaxis and syncope. One confirmed case of anaphylaxis was observed following LAIV, a rate of 1.7 per million LAIV doses. Five confirmed cases of syncope were observed, a rate of 8.5 per million doses. CONCLUSIONS: In a study of trivalent LAIV safety in a large cohort of children, few serious adverse events were detected. Anaphylaxis and syncope occurred following LAIV, although rarely. These data provide reassurance regarding continued LAIV use.

The Content Validity of a Chemotherapy-Induced Peripheral Neuropathy Patient-Reported Outcome Measure.

PURPOSE/OBJECTIVES: To test the content validity of a 16-item version of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy (QLQ-CIPN20). 
. RESEARCH APPROACH: Cross-sectional, prospective, qualitative design. 
. SETTING: Six outpatient oncology clinics within the University of Michigan Health System's comprehensive cancer center in Ann Arbor. 
. PARTICIPANTS: 25 adults with multiple myeloma or breast, gynecologic, gastrointestinal, or head and neck malignancies experiencing peripheral neuropathy caused by neurotoxic chemotherapy. 
. METHODOLOGIC APPROACH: Cognitive interviewing methodology was used to evaluate the content validity of a 16-item version of the QLQ-CIPN20 instrument.
. FINDINGS: Minor changes were made to three questions to enhance readability. Twelve questions were revised to define unfamiliar terminology, clarify the location of neuropathy, and emphasize important aspects. One question was deleted because of clinical and conceptual redundancy with other items, as well as concerns regarding generalizability and social desirability. 
. INTERPRETATION: Cognitive interviewing methodology revealed inconsistencies between patients' understanding and researchers' intent, along with points that required clarification to avoid misunderstanding. 
. IMPLICATIONS FOR NURSING: Patients' interpretations of the instrument's items were inconsistent with the intended meanings of the questions. One item was dropped and others were revised, resulting in greater consistency in how patients, clinicians, and researchers interpreted the items' meanings and improving the instrument's content validity. Following additional revision and psychometric testing, the QLQ-CIPN20 could evolve into a gold-standard CIPN patient-reported outcome measure.

Caffeine Concentrations in Coffee, Tea, Chocolate, and Energy Drink Flavored E-liquids.

INTRODUCTION: Most electronic cigarettes (e-cigarettes) contain a solution of propylene glycol/glycerin and nicotine, as well as flavors. E-cigarettes and their associated e-liquids are available in numerous flavor varieties. A subset of the flavor varieties include coffee, tea, chocolate, and energy drink, which, in beverage form, are commonly recognized sources of caffeine. Recently, some manufacturers have begun marketing e-liquid products as energy enhancers that contain caffeine as an additive. METHODS: A Gas Chromatography-Mass Spectrometry (GC-MS) method for the quantitation of caffeine in e-liquids was developed, optimized and validated. The method was then applied to assess caffeine concentrations in 44 flavored e-liquids from cartridges, disposables, and refill solutions. Products chosen were flavors traditionally associated with caffeine (ie, coffee, tea, chocolate, and energy drink), marketed as energy boosters, or labeled as caffeine-containing by the manufacturer. RESULTS: Caffeine was detected in 42% of coffee-flavored products, 66% of tea-flavored products, and 50% of chocolate-flavored e-liquids (limit of detection [LOD] - 0.04 µg/g). Detectable caffeine concentrations ranged from 3.3 µg/g to 703 µg/g. Energy drink-flavored products did not contain detectable concentrations of caffeine. Eleven of 12 products marketed as energy enhancers contained caffeine, though in widely varying concentrations (31.7 µg/g to 9290 µg/g). CONCLUSIONS: E-liquid flavors commonly associated with caffeine content like coffee, tea, chocolate, and energy drink often contained caffeine, but at concentrations significantly lower than their dietary counterparts. Estimated daily exposures from all e-cigarette products containing caffeine were much less than ingestion of traditional caffeinated beverages like coffee. IMPLICATIONS: This study presents an optimized and validated method for the measurement of caffeine in e-liquids. The method is applicable to all e-liquid matrices and could potentially be used to ensure regulatory compliance for those geographic regions that forbid caffeine in e-cigarette products. The application of the method shows that caffeine concentrations and estimated total caffeine exposure from e-cigarette products is significantly lower than oral intake from beverages. However, because very little is known about the effects of caffeine inhalation, e-cigarette users should proceed with caution when using caffeine containing e-cigarette products. Further research is necessary to determine associated effects from inhaling caffeine.

Discordance Between Perioperative Antibiotic Prophylaxis and Wound Infection Cultures in Patients Undergoing Pancreaticoduodenectomy.

IMPORTANCE: Wound infections after pancreaticoduodenectomy (PD) are common. The standard antibiotic prophylaxis given to prevent the infections is often a cephalosporin. However, this decision is rarely guided by microbiology data pertinent to PD, particularly in patients with biliary stents. OBJECTIVE: To analyze the microbiology of post-PD wound infection cultures and the effectiveness of institution-based perioperative antibiotic protocols. DESIGN, SETTING, AND PARTICIPANTS: The pancreatic resection databases of 3 institutions (designated as institutions A, B, or C) were queried on patients undergoing PD from June 1, 2008, to June 1, 2013, and a total of 1623 patients were identified. Perioperative variables as well as microbiology data for intraoperative bile and postoperative wound cultures were analyzed from June 1, 2008, to June 1, 2013. INTERVENTIONS: Perioperative antibiotic administration. MAIN OUTCOMES AND MEASURES: Wound infection microbiology analysis and resistance patterns. RESULTS: Of the 1623 patients who underwent PD, 133 with wound infections (8.2%) were identified. The wound infection rate did not differ significantly across the 3 institutions. The predominant perioperative antibiotics used at institutions A, B, and C were cefoxitin sodium, cefazolin sodium with metronidazole, and ampicillin sodium-sulbactam sodium, respectively. Of the 133 wound infections, 89 (67.1%) were deep-tissue infection, occurring at a median of 8 (range, 1-57) days after PD. A total of 53 (40.0%) of the wound infections required home visiting nurse services on discharge, and 73 (29.1%) of all PD readmissions were attributed to wound infection. Preoperative biliary stenting was the strongest predictor of postoperative wound infection (odds ratio, 2.5; 95% CI, 1.58-3.88; P = .03). There was marked institutional variation in the type of microorganisms cultured from both the intraoperative bile and wound infection cultures (Streptococcus pneumoniae, 114 cultures [47.9%] in institution A vs 3 [4.5%] in institution B; P = .001) and wound infection cultures (predominant microorganism in institution A: Enterococcus faecalis, 18 cultures [51.4%]; institution B: Staphylococcus aureus, 8 [43.9%]; and institution C: Escherichia coli, 17 [36.2%], P = .001). Similarly, antibiotic resistance patterns varied (resistance pattern in institution A: cefoxitin, 29 cultures [53.1%]; institution B: ampicillin-sulbactam, 9 [69.2%]; and institution C: penicillin, 32 [72.7%], P < .001). Microorganisms isolated in intraoperative bile cultures were similar to those identified in wound cultures in patients with post-PD wound infections. CONCLUSIONS AND RELEVANCE: The findings of this large-scale, multi-institutional study indicate that intraoperative bile cultures should be routinely obtained in patients who underwent preoperative endoscopic retrograde cholangiopancreatography since the isolated microorganisms closely correlate with those identified on postoperative wound cultures. Institution-specific internal reviews should amend current protocols for antibiotic prophylaxis to reduce the incidence of wound infections following PD.

Granulomatous Rosacea and Periorificial Dermatitis: Controversies and Review of Management and Treatment.

Granulomatous rosacea and periorificial dermatitis are common skin conditions affecting the face. This article examines the historical origin, causes, clinical presentation, and management strategies for these entities.

Improved blood pressure control associated with a large-scale hypertension program.

IMPORTANCE: Hypertension control for large populations remains a major challenge. OBJECTIVE: To describe a large-scale hypertension program in Northern California and to compare rates of hypertension control in that program with statewide and national estimates. DESIGN, SETTING, AND PATIENTS: The Kaiser Permanente Northern California (KPNC) hypertension program included a multifaceted approach to blood pressure control. Patients identified as having hypertension within an integrated health care delivery system in Northern California from 2001-2009 were included. The comparison group comprised insured patients in California between 2006-2009 who were included in the Healthcare Effectiveness Data and Information Set (HEDIS) commercial measurement by California health insurance plans participating in the National Committee for Quality Assurance (NCQA) quality measure reporting process. A secondary comparison group was included to obtain the reported national mean NCQA HEDIS commercial rates of hypertension control between 2001-2009 from health plans that participated in the NCQA HEDIS quality measure reporting process. MAIN OUTCOMES AND MEASURES: Hypertension control as defined by NCQA HEDIS. RESULTS: The KPNC hypertension registry included 349,937 patients when established in 2001 and increased to 652,763 by 2009. The NCQA HEDIS commercial measurement for hypertension control within KPNC increased from 43.6% (95% CI, 39.4%-48.6%) to 80.4% (95% CI, 75.6%-84.4%) during the study period (P < .001 for trend). In contrast, the national mean NCQA HEDIS commercial measurement increased from 55.4% to 64.1%. California mean NCQA HEDIS commercial rates of hypertension were similar to those reported nationally from 2006-2009 (63.4% to 69.4%). CONCLUSIONS AND RELEVANCE: Among adults diagnosed with hypertension, implementation of a large-scale hypertension program was associated with a significant increase in hypertension control compared with state and national control rates. Key elements of the program included a comprehensive hypertension registry, development and sharing of performance metrics, evidence-based guidelines, medical assistant visits for blood pressure measurement, and single-pill combination pharmacotherapy.
