Platelet-Rich Plasma Injections for Shoulder Adhesive Capsulitis Are at Least Equivalent to Corticosteroid or Saline Solution Injections: A Systematic Review of Prospective Cohort Studies.

PURPOSE: To evaluate the role of platelet-rich plasma (PRP) for adhesive capsulitis (AC) as compared with other injectables. METHODS: A literature search of the PubMed and Embase online databases was performed to identify articles evaluating injection therapy for the treatment of AC. The inclusion criteria included prospective studies comparing PRP against alternative injectables with a minimum of 15 patients in each treatment arm and a minimum 12-week follow-up period. Pain scores, range of motion, and function scores were the primary outcomes assessed. RESULTS: Five articles comparing PRP with corticosteroid or saline solution injections met the inclusion criteria. A total of 157 patients were treated with PRP, with a follow-up duration ranging from 3 to 6 months. All 5 studies showed statistically significant improvements in pain scores, motion, and function scores in patients receiving PRP, corticosteroid, and saline solution injections. However, PRP was consistently superior on intergroup analyses in all but 1 study. In 4 studies, pain and function scores favored PRP over control at final follow-up (range in mean difference, -2.2 to 0.69 for visual analog scale pain score [n = 5] and -50.5 to -4.0 for Shoulder Pain and Disability Index score [n = 3]), whereas 3 studies found greater improvement in shoulder motion after PRP (range in mean difference, 0.7° to 34.3° for forward flexion and -2.3° to 20.4° for external rotation [n = 4]). One study found no significant difference between PRP and corticosteroid injections but noted that the results were comparable. CONCLUSIONS: According to a limited number of prospective studies, PRP injections for AC are at least equivalent to corticosteroid or saline solution injections and often lead to improved pain, motion, and functional outcomes at 3- to 6-month follow-up. Given the small number of studies, with design heterogeneity, there is insufficient evidence to routinely recommend PRP for AC. However, the results are promising and do support considering PRP as an adjunct treatment option for AC, especially for patients refractory and/or averse to corticosteroids or alternative treatment modalities. LEVEL OF EVIDENCE: Level II, systematic review of Level I and II studies.

Perioperative Sleep Quality Disturbances in Total Joint Arthroplasty is Multifactorial.

BACKGROUND: Sleep quality following arthroplasty procedures is important for patient recovery and satisfaction, but remains poorly understood. The purpose of this study was to report risk factors for sleep disturbances in the perioperative period in patients undergoing primary total joint arthroplasty procedures. METHODS: Sleep surveys were prospectively collected on 751 consecutive patients undergoing total joint arthroplasty at our institution between June 2019 and February 2021 at their preoperative and postoperative visits (2 and 6 weeks). Data were collected on patient demographics, opioid use (preoperatively and postoperatively) as well as tobacco and alcohol use, and specific medical diagnosis that may influence sleep patterns (ie, depression). Statistical analyses were performed using the Student's t-tests and 1-way analysis of variances. RESULTS: For both total hip and total knee patients, worse sleep patterns preoperatively were found in patients who used opioids prior to surgery (P < .001), were current smokers (P < .001), and were aged less than 65 years (P < .001). Postoperative persistent opioid use (more than 3 months) was seen in patients who had worse reported sleep quality preoperatively (P < .001). In comparison to total hip arthroplasty, patients who underwent total knee arthroplasty were more likely to report less sleep in the postoperative period. Patients who were current smokers (compared to nonsmokers or previous smokers) (P = .014) had worse sleep quality at all time points that persisted at 6 weeks, although these differences were seen more in total hip patients than in total knee patients (P = .006 versus P = .059). CONCLUSIONS: Sleep quality disturbances around the time of surgery appear to be multifactorial. LEVEL OF EVIDENCE: Therapeutic Level III.

B Cell-Activating Factor Antagonism Attenuates the Growth of Experimental Abdominal Aortic Aneurysm.

B cell-activating factor (BAFF), part of a tumor necrosis factor family of cytokines, was recently identified as a regulator of atherosclerosis; however, its role in aortic aneurysm has not been determined. Here, the study examined the effect of selective BAFF antagonism using an anti-BAFF antibody (blocks binding of BAFF to receptors BAFF receptor 3, transmembrane activator and CAML interactor, and B-cell maturation antigen) and mBaffR-mFc (blocks binding of BAFF to BAFF receptor 3) on a murine model of abdominal aortic aneurysm (AAA). In a prevention strategy, the antagonists were injected before the induction of AAA, and in an intervention strategy, the antagonists were injected after the induction of AAA. Both strategies attenuated the formation of AAA. In the intervention group, BAFF antagonism depleted most of the mature B-cell subsets in spleen and circulation, leading to enhanced resolution of inflammation in AAA as indicated by decreased infiltration of B cells and proinflammatory macrophages and a reduced number of apoptotic cells. In AAA tissues, B cells and macrophages were found in close contact. In vitro, B cells, irrespective of treatment with BAFF, impaired the efferocytosis activity of macrophages, suggesting a direct innate role of B cells on macrophage function. Altogether, BAFF antagonism affects survival of the mature B cells, promotes resolution of inflammation in the aorta, and attenuates the growth of AAA in mice.

Pharmacologic inhibition of transient receptor channel vanilloid 4 attenuates abdominal aortic aneurysm formation.

Abdominal aortic aneurysm (AAA) formation is characterized by inflammation, leukocyte infiltration, and vascular remodeling. This study investigates the role of TRPV4 channels, which are transmembrane calcium channels that can regulate vascular tone, in modulating AAA formation. The elastase-treatment model of AAA in C57BL6 (WT) mice and Angiotensin II treatment model in ApoE-/- mice were used to confirm our hypotheses. The administration of a specific TRPV4 antagonist, GSK2193874, in elastase-treated WT mice and in AngII-treated ApoE-/- mice caused a significant attenuation of aortic diameter, decrease in pro-inflammatory cytokines (IL-1ß, IL-6, IL-17, MCP-1, MIP-1α, MIP-2, RANTES, and TNF-α), inflammatory cell infiltration (CD3 + T cells, macrophages, and neutrophils), elastic fiber disruption, and an increase in smooth muscle cell α-actin expression compared to untreated mice. Similarly, elastase-treated TRPV4-/- mice had a significant decrease in AAA formation, aortic inflammation, and vascular remodeling compared to elastase-treated WT mice on Day 14. In vitro studies demonstrated that the inhibition of TRPV4 channels mitigates aortic smooth muscle cell-dependent inflammatory cytokine production as well as decreases neutrophil transmigration through aortic endothelial cells. Therefore, our results suggest that TRPV4 antagonism can attenuate aortic inflammation and remodeling via decreased smooth muscle cell activation and neutrophil transendothelial migration during AAA formation.

Sex-Based Differences Among Experimental Swine Abdominal Aortic aneurysms.

BACKGROUND: Female sex protects against abdominal aortic aneurysms (AAAs); however, the mechanisms behind these sex-based differences remain unknown. The purpose of this study was to explore the role of sex and sex hormones in AAA formation among swine. MATERIALS AND METHODS: Using a previous validated model, infrarenal AAA were surgically created in uncastrated male (n = 8), female (n = 5), and castrated male (n = 4) swine. Aortic dilation was measured on postoperative day 28 during the terminal procedure and compared to initial aortic diameter measured during the index procedure. Tissue was analyzed for immunohistochemistry, cytokine array, gelatin zymography, serum 17ß-estradiol, and testosterone assay. RESULTS: Uncastrated males had significantly larger maximal aortic dilation compared to castrated males (113.5% ± 11.4% versus 38.1% ± 4.5%, P = 0.0012). Females had significantly higher mean aortic dilation compared to castrated males (96.2% ± 7.5% versus 38.1% ± 4.5%, P = 0.0004). Aortic diameters between females and uncastrated males were not significantly different on day 28. Female swine had significantly higher concentrations of 17ß-estradiol compared with uncastrated males (1590 ± 873.3 ng/mL versus 95.2 ± 2.3 ng/mL, P = 0.047), with no significant difference between females and castrated males. Uncastrated male AAA demonstrated significantly more elastin degradation compared with female and castrated males (P = 0.01 and <0 .01, respectively). No differences existed for T-cells or smooth muscle cells between groups. Multiple proinflammatory cytokines were elevated within uncastrated male aortic walls compared to females and castrated males. CONCLUSIONS: Sex hormones, specifically 17ß-estradiol and testosterone, influence experimental swine AAA formation as demonstrated by increased aneurysm size, collagen turnover, and elastolysis in uncastrated males in processes reflective of human disease.

Female Mice Exhibit Abdominal Aortic Aneurysm Protection in an Established Rupture Model.

BACKGROUND: Male gender is a well-established risk factor for abdominal aortic aneurysm (AAA), whereas estrogen is hypothesized to play a protective role. Although rupture rates are higher in women, these reasons remain unknown. In the present study, we sought to determine if female mice are protected from AAA rupture. MATERIALS AND METHODS: Apolipoprotein E-deficient male and female mice (aged 7 wk; n = 25 per group) were infused with angiotensin II (AngII; 2000 ng/kg/min) plus ß-aminopropionitrile (BAPN) in the drinking water for 28 d to test the effects of gender on AAA rupture. Separately, a second group of male apolipoprotein E-deficient mice underwent AngII infusion + BAPN while being fed high-fat phytoestrogen free or a high-fat phytoestrogen diet to assess effects of phytoestrogens on rupture. In a third group, female mice either underwent oophorectomy or sham operation 4 wk before infusion of AngII and BAPN to further test the effects of female hormones on AA rupture. Surviving mice abdominal aorta were collected for histology, cytokine array, and gelatin zymography on postoperative day 28. RESULTS: Female mice had decreased AAA rupture rates (16% versus 46%; P = 0.029). Female mice expressed fewer elastin breaks (P = 0.0079) and decreased smooth muscle cell degradation (P = 0.0057). Multiple cytokines were also decreased in the female group. Gelatin zymography demonstrated significantly decreased pro-matrix metalloproteinase 2 in female mice (P = 0.001). Male mice fed a high dose phytoestrogen diet failed to decrease AAA rupture. Female mice undergoing oophorectomy did not have accelerated aortic rupture. CONCLUSIONS: These data are the first to attempt to tease out hormonal effects on AAA rupture and the possible role of gender in rupture.

ZFP148 (Zinc-Finger Protein 148) Binds Cooperatively With NF-1 (Neurofibromin 1) to Inhibit Smooth Muscle Marker Gene Expression During Abdominal Aortic Aneurysm Formation.

Objective- The goal of this study was to determine the role of ZFP148 (zinc-finger protein 148) in aneurysm formation. Approach and Results- ZFP148 mRNA expression increased at day 3, 7, 14, 21, and 28 after during abdominal aortic aneurysm formation in C57BL/6 mice. Loss of ZFP148 conferred abdominal aortic aneurysm protection using ERTCre+ ZFP148 flx/flx mice. In a third set of experiments, smooth muscle-specific loss of ZFP148 alleles resulted in progressively greater protection using novel transgenic mice (MYH [myosin heavy chain 11] Cre+ flx/flx, flx/wt, and wt/wt). Elastin degradation, LGAL3, and neutrophil staining were significantly attenuated, while α-actin staining was increased in ZFP148 knockout mice. Results were verified in total cell ZFP148 and smooth muscle-specific knockout mice using an angiotensin II model. ZFP148 smooth muscle-specific conditional mice demonstrated increased proliferation and ZFP148 was shown to bind to the p21 promoter during abdominal aortic aneurysm formation. ZFP148 smooth muscle-specific conditional knockout mice also demonstrated decreased apoptosis as measured by decreased cleaved caspase-3 staining. ZFP148 bound smooth muscle marker genes via chromatin immunoprecipitation analysis mediated by NF-1 (neurofibromin 1) promote histone H3K4 deacetylation via histone deacetylase 5. Transient transfections and chromatin immunoprecipitation analyses demonstrated that NF-1 was required for ZFP148 protein binding to smooth muscle marker genes promoters during aneurysm formation. Elimination of NF-1 using shRNA approaches demonstrated that NF-1 is required for binding and elimination of NF-1 increased BRG1 recruitment, the ATPase subunit of the SWI/SWF complex, and increased histone acetylation. Conclusions- ZFP148 plays a critical role in multiple murine models of aneurysm formation. These results suggest that ZFP148 is important in the regulation of proliferation, smooth muscle gene downregulation, and apoptosis in aneurysm development.

"The right time is just after birth": acceptability of point-of-care birth testing in Eswatini: qualitative results from infant caregivers, health care workers, and policymakers.

BACKGROUND: Testing for HIV at birth has the potential to identify infants infected in utero, and allows for the possibility of beginning treatment immediately after birth; point of care (POC) testing allows rapid return of results and faster initiation on treatment for positive infants. Eswatini piloted birth testing in three public maternities for over 2 years. METHODS: In order to assess the acceptability of POC birth testing in the pilot sites in Eswatini, interviews were held with caregivers of HIV-exposed infants who were offered birth testing (N = 28), health care workers (N = 14), and policymakers (N = 10). Participants were purposively sampled. Interviews were held in English or SiSwati, and transcribed in English. Transcripts were coded by line, and content analysis and constant comparison were used to identify key themes for each respondent type. RESULTS: Responses were categorized into: knowledge, experience, opinions, barriers and challenges, facilitators, and suggestions to improve POC birth testing. Preliminary findings reveal that point of care birth testing has been very well received but challenges were raised. Most caregivers appreciated testing the newborns at birth and getting results quickly, since it reduced anxiety of waiting for several weeks. However, having a favorable experience with testing was linked to having supportive and informed family members and receiving a negative result. Caregivers did not fully understand the need for blood draws as opposed to tests with saliva, and expressed the fears of seeing their newborns in pain. They were specifically grateful for supportive nursing staff who respected their confidentiality. Health care workers expressed strong support for the program but commented on the high demand for testing, increased workload, difficulty with errors in the testing machine itself, and struggles to implement the program without sufficient staffing, especially on evenings and weekends when phlebotomists were not available. Policymakers noted that there have been challenges within the program of losing mothers to follow up after they leave hospital, and recommended stronger linkages to community groups. CONCLUSIONS: There is strong support for scale-up of POC birth testing, but countries should consider ways to optimize staffing and manage demand.

A novel swine model of abdominal aortic aneurysm.

OBJECTIVE: Few large-animal models exist for the study of aortic aneurysms. ß-Aminopropionitrile (BAPN) is a compound known to cause aortic aneurysms by inhibiting lysyl oxidase, a collagen cross-linking enzyme. It is hypothesized that BAPN plus aneurysm induction surgery would result in significant aneurysm formation in swine with biologic properties similar to human disease. METHODS: Initial experiments were performed in uncastrated male swine not treated with BAPN (surgery alone). Subsequently, uncastrated male swine were fed BAPN (0.15 g/kg) for 7 days before undergoing surgery; the infrarenal aorta was circumferentially dissected and measured, balloon dilated, and perfused with elastase (500 units) and type I collagenase (8000 units), with extraluminal elastase application. In the BAPN groups, daily BAPN feedings continued until swine harvest at postoperative days 7, 14, and 28. RESULTS: Swine undergoing surgery alone (n = 12) had significantly less dilation at 28 days compared with BAPN + surgery swine (51.9% ± 29.2% [0%-100%] vs 113.5% ± 30.2% [52.9%-146.2%]; P < .0003). Mean aortic dilation in animals undergoing treatment with surgery and BAPN was 86.9% ± 47.4% (range, 55.6%-157.1%), 105.4% ± 58.1% (50%-133.3%), and 113.5% ± 30.2% (52.9%-146.2%) at 7, 14, and 28 days, respectively. In the BAPN + surgery group, significant elastolysis was present at all time points, whereas aortic wall collagen content was not significantly different. Smooth muscle cells were significantly depleted at 14 and 28 days, and M1 macrophages were increased at 14 and 28 days (P < .05, all). Matrix metalloproteinase 2 was elevated at 7 days (P < .05). Multiple proinflammatory cytokines were elevated within the aortic wall of BAPN + surgery swine. CONCLUSIONS: BAPN plus surgery resulted in significantly larger aortic aneurysms than surgery alone and was critical to aneurysm formation in this novel swine model. Hallmarks of human disease, such as elastin fragmentation, smooth muscle cell depletion, macrophage infiltration, matrix metalloproteinase activation, and proinflammatory cytokine expression, were observed in BAPN-treated swine. This model better parallels many of the characteristics of human AAAs and may be suitable for prehuman drug trials.

Resolvin D1 decreases abdominal aortic aneurysm formation by inhibiting NETosis in a mouse model.

OBJECTIVE: Resolvins have been shown to attenuate inflammation, whereas NETosis, the process of neutrophils releasing neutrophil extracellular traps (NETs), produces increased inflammation. It is hypothesized that treatment of animals with resolvin D1 (RvD1) would reduce abdominal aortic aneurysm (AAA) formation by inhibiting NETosis. METHODS: Wild-type 8- to 12-week-old C57BL/6 male mice (n = 47) and apolipoprotein E-deficient (ApoE-/-) mice (n = 20) were used in two models to demonstrate the effects of RvD1 on AAA growth. In the topical elastase AAA model, wild-type mice were divided into three groups: a deactivated elastase control group, in which sham surgery was performed using deactivated elastase and mice were intravenously injected with phosphate-buffered saline (PBS) once a day until harvest; an elastase group, in which active elastase was used to induce AAA and mice were injected with PBS daily until harvest; and an RvD1-treated group, in which AAA was induced and mice were injected with RvD1 daily until harvest. In the angiotensin II (Ang II)-induced AAA model, ApoE-/- mice were fed a high-fat diet and implanted with osmotic infusion pumps containing Ang II (1000 ng/kg/min). The Ang II model was divided into two groups: an Ang II control group, in which Ang II was delivered and mice were injected with PBS daily until harvest; and an RvD1-treated group, in which Ang II was delivered and mice were injected with RvD1 daily until harvest. On postoperative day 3, day 14, or day 28, aortic and blood samples were collected for Western blot, histology, cytokine array, enzyme-linked immunosorbent assay, and gelatin zymography after aortic diameter measurement. RESULTS: The day 14 RvD1-treated group demonstrated 42% reduced AAA diameter compared with the elastase group (P < .001). On postoperative day 3, the RvD1-treated group showed decreased levels of NETosis markers citrullinated histone H3 (P = .04) and neutrophil elastase (P = .002) compared with the elastase group. Among important cytokines involved in AAA formation, interleukin (IL) 1ß was downregulated (P = .02) whereas IL-10, a protective cytokine, was upregulated (P = .01) in the RvD1-treated group. Active matrix metalloproteinase 2 also decreased in the RvD1-treated group (P = .03). The RvD1-treated group in the Ang II AAA model, a second model, demonstrated reduced AAA diameter compared with the Ang II control group on day 28 (P < .046). The RvD1-treated group showed decreased levels of citrullinated histone H3 on day 3 (P = .002). Cytokines interferon γ, IL-1ß, C-X-C motif chemokine ligand 10, monocyte chemotactic protein 1, and regulated on activation, normal T cell expressed and secreted (RANTES) were all decreased on day 28 (P < .05). CONCLUSIONS: RvD1-mediated inhibition of NETosis may represent a future medical treatment for the attenuation of AAA growth.

Alzheimer's disease severity and its association with patient and caregiver quality of life in Japan: results of a community-based survey.

BACKGROUND: Alzheimer's disease (AD) dementia, a progressive neurodegenerative disease, exerts significant burden upon patients, caregivers, and healthcare systems globally. The current study investigated the associations between AD dementia patient disease severity and health-related quality of life (HRQoL) of both patients (proxy report) and their caregivers living in Japan, as well as caregiving-related comorbidities such as depression. METHODS: This cross-sectional study used self-reported data from caregivers of people diagnosed with AD dementia by a healthcare provider in Japan. Caregivers were identified via online panels and invited to participate in an online survey between 2014 and 2015. Caregivers completed survey items for themselves, in addition to providing proxy measures for patients with AD dementia for whom they were caring. Patient and caregiver HRQoL was measured using the EuroQoL 5-Dimension (EQ-5D). Additional outcomes for caregivers of AD dementia patients included the Patient Health Questionnaire (PHQ-9) of depressive symptomology, as well as comorbidities experienced since initiating caregiving for their AD dementia patients. These outcomes were examined as a function of AD dementia severity, as measured by long-term care insurance (LTCI) categories. Bivariate analyses between LTCI and outcomes were conducted using independent t-tests and chi-square tests. Multivariable analyses, controlling for potential confounders, were conducted using generalized linear models (GLMs) specifying a normal distribution. RESULTS: Across 300 caregiver respondents, multivariable results revealed that increasing AD dementia severity was significantly associated with poorer patient and caregiver EQ-5D scores and a high proportion of caregivers (30.0%) reported PHQ-9 scores indicative of major depressive disorder (MDD). The most frequent comorbidities experienced after becoming caregivers of AD dementia patients included hypertension (12.7%) and insomnia (11.0%). Depression and other comorbidities did not differ significantly by patient severity. CONCLUSIONS: The current study provides unique insight into the specific degree of incremental burden associated with increasing AD dementia severity among patients and caregivers alike. Importantly, greater disease severity was associated with poorer quality of life among both patients and caregivers. These results suggest that earlier detection and treatment of AD dementia may provide an opportunity to reduce the burden of disease for patients, caregivers, and society at large.

Real-world Effectiveness of Antipsychotics for the Treatment of Negative Symptoms in Patients with Schizophrenia with Predominantly Negative Symptoms.

This study assessed the comparative effectiveness of antipsychotics in the treatment of patients with schizophrenia presenting with prominent negative symptoms and no-to-mild positive symptoms. Data were taken from a 3-year prospective, international, observational study (n=17 384). This post-hoc study focused on 3 712 patients who started antipsychotic monotherapy and had moderate-to-severe negative symptoms and no-to-mild positive symptoms (Clinical Global Impression-Severity Scale [GGI-SCH]). Patients were classified into 3 treatment cohorts: olanzapine, other atypicals and typicals. Multiple regression analyses were performed. All treatment groups experienced improvement in negative symptoms and social functioning during follow-up. The adjusted mean change in the CGI-SCH negative symptoms scores during follow-up was greater for olanzapine-treated patients by 0.220 (p<0.001) (vs. other atypicals) and by 0.453 (p<0.001) (vs. typicals). Olanzapine-treated patients were also most likely to achieve response of negative symptoms and improvement in social functioning, and to stay on the initial medication longer. Patients with schizophrenia treated with antipsychotics experienced improvement in negative symptoms and social functioning during follow-up. Olanzapine appeared to be more effective compared with other antipsychotics.

Factors associated with and impact of pain persistence in Asian patients with depression: a 3-month, prospective observational study.

OBJECTIVE: We investigated the depression outcomes and the factors associated with pain persistence in Asian patients treated for major depressive disorder (MDD). METHODS: This observational study enrolled 909 Asian adult inpatients and outpatients. The presence or absence of painful physical symptoms and severity of depression were assessed at baseline and after three months of treatment. Factors associated with pain persistence and outcome of depression were investigated using regression methods. RESULTS: Of the 909 patients enrolled, 684 were included in the analysis and evaluated at three months. Of them, 335 (49%) had no pain at baseline nor follow up, 198 (29%) at baseline but not at follow up and 151 (22%) in both assessments. Pain more frequently persisted in patients who were divorced/widowed/separated, with >1 comorbidity, aged <40 years, with previous MDD episodes, taking pain medications, and with greater depression severity. At three months, response/remission were 84%/73% in the no pain group, 83%/63% in the remitted pain group and 46%/25% in the persistent pain group (differences all p < .0001; all bivariate comparisons were statistically significant with p < .05 except response between no pain and remitted pain). Persistent pain was also associated with less improvement in quality of life and health state. CONCLUSIONS: Pain should be taken into account when diagnosing MDD and when tailoring therapy.

Part 2: Evidence Evaluation and Management of Conflicts of Interest: 2015 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations.

The process for evaluating the resuscitation science has evolved considerably over the past 2 decades. The current process, which incorporates the use of the GRADE methodology, culminated in the 2015 CoSTR publication, which in turn will inform the international resuscitation councils' guideline development processes. Over the next few years, the process will continue to evolve as ILCOR moves toward a more continuous evaluation of the resuscitation science.

Cardiac arrest and cardiopulmonary resuscitation outcome reports: update of the Utstein Resuscitation Registry Templates for Out-of-Hospital Cardiac Arrest: a statement for healthcare professionals from a task force of the International Liaison Committee on Resuscitation (American Heart Association, European Resuscitation Council, Australian and New Zealand Council on Resuscitation, Heart and Stroke Foundation of Canada, InterAmerican Heart Foundation, Resuscitation Council of Southern Africa, Resuscitation Council of Asia); and the American Heart Association Emergency Cardiovascular Care Committee and the Council on Cardiopulmonary, Critical Care, Perioperative and Resuscitation.

Utstein-style guidelines contribute to improved public health internationally by providing a structured framework with which to compare emergency medical services systems. Advances in resuscitation science, new insights into important predictors of outcome from out-of-hospital cardiac arrest, and lessons learned from methodological research prompted this review and update of the 2004 Utstein guidelines. Representatives of the International Liaison Committee on Resuscitation developed an updated Utstein reporting framework iteratively by meeting face to face, by teleconference, and by Web survey during 2012 through 2014. Herein are recommendations for reporting out-of-hospital cardiac arrest. Data elements were grouped by system factors, dispatch/recognition, patient variables, resuscitation/postresuscitation processes, and outcomes. Elements were classified as core or supplemental using a modified Delphi process primarily based on respondents' assessment of the evidence-based importance of capturing those elements, tempered by the challenges to collect them. New or modified elements reflected consensus on the need to account for emergency medical services system factors, increasing availability of automated external defibrillators, data collection processes, epidemiology trends, increasing use of dispatcher-assisted cardiopulmonary resuscitation, emerging field treatments, postresuscitation care, prognostication tools, and trends in organ recovery. A standard reporting template is recommended to promote standardized reporting. This template facilitates reporting of the bystander-witnessed, shockable rhythm as a measure of emergency medical services system efficacy and all emergency medical services system-treated arrests as a measure of system effectiveness. Several additional important subgroups are identified that enable an estimate of the specific contribution of rhythm and bystander actions that are key determinants of outcome.

Impact of caring for persons with Alzheimer's disease or dementia on caregivers' health outcomes: findings from a community based survey in Japan.

BACKGROUND: This study assessed how family caregivers for patients with Alzheimer's disease (AD) or dementia in Japan differed from non-caregivers in characteristics and health outcomes (i.e., comorbidities, health-related quality of life [HRQoL], productivity, and resource use). Caregivers were hypothesized to experience significantly poorer outcomes than non-caregivers. METHODS: Data were combined from the 2012 and 2013 National Health and Wellness Survey in Japan (n = 60000). Caregivers for adult relatives with AD or dementia were compared with non-caregivers on: comorbidities (including Patient Health Questionnaire (PHQ-9) cutoff scores suggesting presence/absence of major depressive disorder (MDD)), Work Productivity and Activity Impairment (WPAI), SF-36v2-based HRQoL, and healthcare resource utilization. Sociodemographic characteristics, health characteristics and behaviors, and Charlson comorbidity index (CCI) scores were compared across groups. Propensity matching, based on scores generated from a logistic regression predicting caregiving, was used to match caregivers with non-caregivers with similar likelihood of being caregivers. Bivariate comparisons across matched groups served to estimate outcomes differences due to caregiving. RESULTS: Among 55060 respondents, compared with non-caregivers (n = 53758), caregivers (n = 1302) were older (52.6 vs. 47.5 years), more frequently female (53 % vs. 49 %), married/partnered, frequent alcohol drinkers, current smokers, exercisers, and not employed, and they averaged higher CCI scores (0.37 vs. 0.14), all p < 0.05. Propensity scores incorporated sex, age, body mass index (BMI), exercise, alcohol, smoking, marital status, CCI, insured status, education, employment, income, and children in household. A greedy matching algorithm produced 1297 exact matches, excluding 5 non-matched caregivers. Health utilities scores were significantly lower among caregivers (0.724) vs. non-caregivers (0.764), as were SF-36v2 Physical and Mental Component Summary scores. Caregivers vs. non-caregivers had significantly higher absenteeism, presenteeism-related impairment, overall work impairment (25.8 % vs. 20.4 %, respectively), and activity impairment (25.4 % vs. 21.8 %), more emergency room and traditional provider visits (7.70 vs. 5.35) in the past six months, and more frequent MDD (14 % vs. 9 %), depression, insomnia, anxiety, and pain. CONCLUSIONS: Those providing care for patients with AD or dementia in Japan experienced significantly poorer HRQoL and greater comorbid risk, productivity impairment, and resource use. These findings inform the need for greater support for caregivers and their patients.

The incremental burden of pain in patients with depression: results of a Japanese survey.

BACKGROUND: Major depressive disorder (MDD) is a chronic mental illness which affects an estimated 3% of the Japanese population. Many patients with MDD report painful physical symptoms, and research outside of Japan suggests such patients may represent a subtype of depression which is more severe and difficult to treat. There is no evidence available about the characteristics or incremental burden of these patients in Japan. The objective of this study was to quantify the incremental burden of physical pain among individuals in Japan diagnosed with depression. METHODS: Data for individuals age 18 and older who reported a physician diagnosis of depression were obtained from the Japan National Health and Wellness Survey (NHWS). Respondents who also reported physical pain were matched to respondents who did not report pain using propensity scores and compared using bivariate statistics. Measures included Patient Health Questionnaire (PHQ-9) for depression severity, Medical Outcomes Study 12-Item Short Form Survey Instrument (SF-12v2) for health-related quality of life, the Work Productivity and Activity Impairment (WPAI) for work and activity impairment, and 6-month report of health care use. RESULTS: Individuals with depression who reported physical pain had higher PHQ-9 depression scores (14.3 vs. 11.1, p<0.001), lower health-related quality of life (Mental Component Summary score [MCS] 29.1 vs. 32.0, p<0.01; Physical Component Summary score [PCS] 43.0 vs. 47.2, p<0.001; health utility [SF-6D] 0.567 vs. 0.613, p<0.001), more presenteeism (46.3% vs. 36.8%, p<0.01), more overall work impairment (51.4% vs. 42.3%, p<0.01), more activity impairment (55.4% vs. 43.9%, p<0.001), and reported using more health care provider visits in the prior 6 months (17.7 vs. 12.8, p<0.01) as well as hospitalizations (1.7 vs. 0.8, p<0.05) relative to propensity-score matched controls without pain. Absenteeism (13.1% vs. 11.4%, p=0.51) and emergency room visits (0.31 vs. 0.35, p=0.76) were not significantly different between the two matched groups. CONCLUSIONS: Individuals whose depression is accompanied by physical pain have a higher burden of illness than those whose depression does not include physical pain. Clinicians should take the presence of pain into account and consider treating both the physical and emotional symptoms of these patients.
