RESUMO

Individuals with established cardiovascular disease or a high burden of cardiovascular risk factors may be particularly vulnerable to develop complications from coronavirus disease 2019 (COVID-19). We conducted a prospective cohort study at a tertiary care center to identify risk factors for in-hospital mortality and major adverse cardiovascular events (MACE; a composite of myocardial infarction, stroke, new acute decompensated heart failure, venous thromboembolism, ventricular or atrial arrhythmia, pericardial effusion, or aborted cardiac arrest) among consecutively hospitalized adults with COVID-19, using multivariable binary logistic regression analysis. The study population comprised 586 COVID-19 positive patients. Median age was 67 (IQR: 55 to 80) years, 47.4% were female, and 36.7% had cardiovascular disease. Considering risk factors, 60.2% had hypertension, 39.8% diabetes, and 38.6% hyperlipidemia. Eighty-two individuals (14.0%) died in-hospital, and 135 (23.0%) experienced MACE. In a model adjusted for demographic characteristics, clinical presentation, and laboratory findings, age (odds ratio [OR], 1.28 per 5 years; 95% confidence interval [CI], 1.13 to 1.45), previous ventricular arrhythmia (OR, 18.97; 95% CI, 3.68 to 97.88), use of P2Y12-inhibitors (OR, 7.91; 95% CI, 1.64 to 38.17), higher C-reactive protein (OR, 1.81: 95% CI, 1.18 to 2.78), lower albumin (OR, 0.64: 95% CI, 0.47 to 0.86), and higher troponin T (OR, 1.84; 95% CI, 1.39 to 2.46) were associated with mortality (p <0.05). After adjustment for demographics, presentation, and laboratory findings, predictors of MACE were higher respiratory rates, altered mental status, and laboratory abnormalities, including higher troponin T (p <0.05). In conclusion, poor prognostic markers among hospitalized patients with COVID-19 included older age, pre-existing cardiovascular disease, respiratory failure, altered mental status, and higher troponin T concentrations.

RESUMO

OBJECTIVE: Hematologic cancer patients with Coronavirus Disease 2019 (COVID-19) tend to have a more serious disease course than observed in the general population. Herein, we comprehensively reviewed existing literature and analyzed clinical characteristics and mortality of patients with hematologic malignancies and COVID-19. MATERIALS AND METHODS: Through searching PubMed until June 03, 2020, we identified 16 relevant case studies (33 cases) from a total of 45 studies that have reported on patients with COVID-19 and hematologic malignancies. We investigated the clinical and laboratory characteristics including type of hematologic malignancies, initial symptoms, laboratory findings, and clinical outcomes. Then, we compared those characteristics and outcomes of patients with hematologic malignancies and COVID-19 to the general population infected with COVID-19. RESULTS: The median age was 66-year-old. Chronic lymphocytic leukemia was the most common type of hematologic malignancy (39.4%). Fever was the most common symptom (75.9%). Most patients had normal leukocyte counts (55.6%), lymphocytosis (45.4%), and normal platelet counts (68.8%). In comparison to patients with COVID-19 without underlying hematologic malignancies, dyspnea was more prevalent (45.0 vs. 24.9%, p=0.025). Leukocytosis (38.9 vs. 9.8%, p=0.001), lymphocytosis (45.4 vs. 8.2%, p=0.001), and thrombocytopenia (31.3 vs. 11.4%, p=0.036) were significantly more prevalent and lymphopenia (18.2 vs. 57.4%, p=0.012) less prevalent in patients with hematologic malignancies. There were no clinical and laboratory characteristics predicting mortality in patients with hematologic malignancies. Mortality was much higher in patients with hematologic malignancies compared to those without this condition (40.0 vs. 3.6%, p<0.001). CONCLUSIONS: Co-occurrence of hematologic malignancies and COVID-19 is rare. However, due to the high mortality rate from COVID-19 in this vulnerable population, further investigation on tailored treatment and management is required.

RESUMO

BACKGROUND: In Denmark and other countries, there has been a shift in the management of patients with an implantable cardioverter defibrillator (ICD) with remote device monitoring largely replacing in-hospital visits. Less patient-nurse and patient-physician interaction may lead to gaps in patients' quality of care and impede patients' adaptation to living successfully with the ICD. A comprehensive eHealth intervention that include goal-setting, monitoring of symptoms of depression, anxiety, and quality of life, psychological treatment, information provision, supportive tools, online dialogues with nursing staff and access to an online community network, may help fill these gaps and be particularly beneficial to patients who suffer from anxiety and depression. This study will evaluate the effectiveness of the ACQUIRE-ICD care innovation, a comprehensive and interactive eHealth intervention, on patient-reported and clinical outcomes. METHODS: The ACQUIRE-ICD study is a multicenter, prospective, two-arm, unblinded randomised controlled superiority trial that will enroll 478 patients implanted with a first-time ICD or ICD with cardiac synchronisation therapy (CRT-D) from the six implanting centers in Denmark. The trial will evaluate the clinical effectiveness and cost-effectiveness of the ACQUIRE-ICD care innovation, as add-on to usual care compared with usual care alone. The primary endpoint, device acceptance, assessed with the Florida Patient Acceptance Survey, is evaluated at 12 months' post implant. Secondary endpoints, evaluated at 12 and 24 months' post implant, include patient-reported outcomes, return to work, time to first ICD therapy and first hospitalisation, mortality and cost-effectiveness. DISCUSSION: The effectiveness of a comprehensive and interactive eHealth intervention that relies on patient-centred and personalised tools offered via a web-based platform targeted to patients with an ICD has not been assessed so far. The ACQUIRE-ICD care innovation promotes and facilitates that patients become active participants in the management of their disease, and as such addresses the need for a more patient-centered disease-management approach. If the care innovation proves to be beneficial to patients, it may not only increase patient empowerment and quality of life but also free up time for clinicians to care for more patients. TRIAL REGISTRATION: The trial has been registered on https://clinicaltrials.gov/ct2/show/NCT02976961 on November 30, 2016 with registration number [ NCT02976961 ].

RESUMO

Secondary caries at the tooth-resin interface is the primary reason for replacement of resin composite restorations. The tooth-resin interface is formed by the interlocking of resin material with hydroxyapatite crystals in enamel and collagen mesh structure in dentin. Efforts to strengthen the tooth-resin interface have identified chemical agents with dentin collagen cross-linking potential and antimicrobial activities. The purpose of the present study was to assess protective effects of bioactive primer against secondary caries development around enamel and dentin margins of class V restorations, using an in vitro bacterial caries model. Class V composite restorations were prepared on 60 bovine teeth (n=15) with pretreatment of the cavity walls with control buffer solution, an enriched fraction of grape seed extract (e-GSE), 1-ethyl-3-(3-dimethyl aminopropyl)-carbodiimide/N-hydroxysuccinimide, or chlorhexidine digluconate. After incubating specimens in a bacterial model with Streptococcus mutans for four days, dentin and enamel were assessed by fluorescence microscopy. Results revealed that only the naturally occurring product, e-GSE, significantly inhibited the development of secondary caries immediately adjacent to the dentin-resin interface, as indicated by the caries inhibition zone. No inhibitory effects were observed in enamel margins. The results suggest that the incorporation of e-GSE into components of the adhesive system may inhibit secondary caries and potentially contribute to the protection of highly vulnerable dentin-resin margins.

RESUMO

BACKGROUND: To evaluate response to radiation and clinical outcome of uterine cervical cancer patients with tumor-related leukocytosis (TRL) at initial diagnosis and during definitive radiotherapy. PATIENTS AND METHODS: We retrospectively analyzed 2456 patients with stage IA-IVA uterine cervical cancer who received definitive radiotherapy with (37.4%) or without (62.6%) platinum-based chemotherapy between 1986 and 2012. TRL was defined as two or more occurrences of leukocytosis over 9000/µl at the time of diagnosis and during the course of treatment. Locoregional failure-free survival (LFFS) and overall survival (OS) were compared between patients with or without TRL. RESULTS: The median age of all patients was 55 years, and the median follow-up time was 65.1 months. TRL was observed in 398 patients (16%) at initial diagnosis; TRL (+) patients were younger and had larger tumors, advanced stage, and more frequent lymph node metastases (all P < 0.05). TRL (+) patients showed a significantly lower rate of complete remission than TRL (-) patients (89.9% versus 96.3%, respectively, P = 0.042). Ten-year LFFS and OS for all patients were 84% and 78%, respectively. LFFS and OS were significantly lower in TRL (+) patients than TRL (-) patients (10-year LFFS: 69% versus 87% respectively, P < 0.001; 10-year OS: 63% versus 81% respectively P < 0.001). After propensity score matching, LFFS and OS rates in TRL (+) patients remained significantly lower than for TRL (-) patients; this significant difference was also observed on multivariate analysis. Twenty-six percent of patients with locoregional failure (n = 345) were TRL (+) and had significantly poorer median OS (6 versus 12 months, P = 0.001). CONCLUSION: This study reveals the aggressive nature of cervical cancer with TRL and its poor response to radiation therapy. Given the unfavorable prognosis and higher probability of treatment failure, optimal diagnostic and therapeutic approaches and careful monitoring for early detection of recurrence should be considered for these patients.

RESUMO

BACKGROUND AND PURPOSE: A major concern after emergent intracranial angioplasty in cases of acute stroke with underlying intracranial stenosis is the acute reocclusion of the treated arteries. This study reports the incidence and clinical outcomes of acute reocclusion of arteries following emergent intracranial angioplasty with or without stent placement for the management of patients with acute stroke with underlying intracranial atherosclerotic stenosis. MATERIALS AND METHODS: Forty-six patients with acute stroke received emergent intracranial angioplasty with or without stent placement for intracranial atherosclerotic stenosis and underwent follow-up head CTA. Acute reocclusion was defined as "hypoattenuation" within an arterial segment with discrete discontinuation of the arterial contrast column, both proximal and distal to the hypoattenuated lesion, on CTA performed before discharge. Angioplasty was defined as "suboptimal" if a residual stenosis of ≥50% was detected on the postprocedural angiography. Clinical and radiologic data of patients with and without reocclusion were compared. RESULTS: Of the 46 patients, 29 and 17 underwent angioplasty with and without stent placement, respectively. Acute reocclusion was observed in 6 patients (13%) and was more frequent among those with suboptimal angioplasty than among those without it (71.4% versus 2.6%, P < .001). The relative risk of acute reocclusion in patients with suboptimal angioplasty was 27.857 (95% confidence interval, 3.806-203.911). Furthermore, a good outcome was significantly less frequent in patients with acute reocclusion than in those without it (16.7% versus 67.5%, P = .028). CONCLUSIONS: Acute reocclusion of treated arteries was common after emergent intracranial angioplasty with or without stent placement in patients with acute stroke with intracranial atherosclerotic stenosis and was associated with a poor outcome. Suboptimal results of angioplasty appear to be associated with acute reocclusion, irrespective of whether stent placement was performed.

RESUMO

BACKGROUND: Psoriasis is a chronic skin disorder that detracts from quality of life, including elements of physical, psychological and social functioning. OBJECTIVE: This study investigated whether retrospective questions about chronic quality of life (CQoL) were better predictors of poor socioeconomic and medical outcomes than the current Dermatology Life Quality Index (DLQI). METHODS: One hundred fourteen participants answered the 10 questions used in the standard DLQI for 'over the last week', 'over the last year' and 'over your lifetime with psoriasis'. Subjects were examined and completed a self-administered questionnaire regarding disabilities, relationships, education and medical and economic outcomes (a smaller subset of 58 subjects also answered questions regarding religion and discrimination). RESULTS: Greater lifetime DLQI (LT DLQI) correlated with lower satisfaction with treatment (P = 0.007), greater concern that psoriasis will worsen (P = 0.012), worse perceived general health (P = 0.003), younger age at which weight became problematic (P = 0.002), greater likelihood of believing psoriasis had caused weight gain (P < 0.001), shorter retention of current job (P = 0.001), more experiences of discrimination at work (P = 0.002) and in social settings (P < 0.001) over one's lifetime and more severe discrimination in social settings over one's lifetime (P = 0.002). Greater LT DLQI predicted more packs smoked per day (P = 0.005), greater likelihood of believing psoriasis caused smoking (P = 0.012), greater likelihood of recreational drug use (P = 0.004), greater likelihood of a depression diagnosis (P < 0.001), greater likelihood of having felt depressed (P = 0.011) and greater likelihood of believing psoriasis caused depression (P < 0.001). CONCLUSION: Compared to the standard LW DLQI, LT DLQI was a better predictor of patient outcomes related to weight, discrimination and depression.

RESUMO

BACKGROUND: Electronic claims and medical record databases are important sources of information for medical research. However, potential sources of error and bias, including inaccurate diagnoses, incomplete data, incorrect data entry and misclassification bias, necessitate studies that assess the validity of these databases. OBJECTIVES: To assess the validity of the diagnostic code for hidradenitis suppurativa (HS), which is an increasingly studied disease. METHODS: In this retrospective study, the medical records of 1168 patients in the Massachusetts General Hospital database who had received at least two International Classification of Diseases, Ninth Revision 705·83 codes were manually screened. RESULTS: Of the screened patients, 1046 (89·6%) were confirmed as having HS. The mean age ± SD was 44·0 ± 15·7 years, the median age was 43·0 years and 748 (71·5%) were female. The majority were white (66·7%), while a significant minority were black (13·9%) or Hispanic (13·4%). An increasing number of codes and specific terms used to describe HS in the medical record, including 'hydradenitis', 'boil', 'draining', 'abscess', 'fistula', 'cyst' and 'nodule', could be used to improve the positive predictive value of the search. CONCLUSION: Our results highlight the importance of establishing the validity of diagnostic codes in electronic databases, and allow for refinements of appropriate ways to design future searches. Given the potential for misclassification of patients with HS, establishing the validity of diagnostic codes and search strategies in electronic databases represents a crucial step for subsequent studies utilizing these databases.

RESUMO

Gas phase acidity and basicity estimation models have been developed for acidic and basic functional groups of amino acid side-chains and also for a number of small organic molecules. The acidic functional groups include aliphatic and aromatic alcohol, and aliphatic and aromatic carboxylic acid, and the basic functional groups include aliphatic, aromatic and hetero-aromatic amines, and also pyridino-, pyrazolo- and imidazolo-groupings. The models are described in terms of a linear combination of descriptors that highly influence reactivity at the reaction centres of the functional groups. In order to describe the chemical environments of the deprotonating and protonating sites, atomic descriptors such as the effective atomic electronegativity and effective atomic polarizability of the atoms in the reaction field and the electrostatic potentials at the reaction sites have been introduced. The coefficient of determination (r(2)) of each model is above 0.8, apart from the imidazole model. The models are readily applicable, ranging from simple organic molecules to proteins.

RESUMO

BACKGROUND: Psoriasis is a chronic, inflammatory skin disorder that is associated with obesity. Independently, both psoriasis and obesity likely impose impressive physical and psychosocial burdens on affected patients. OBJECTIVE: The purpose of this study was to evaluate the relative impact of body mass index (BMI) on the socioeconomic status, medical co-morbidities, and current and chronic quality of life of psoriasis patients. METHODS: Overall, 114 subjects were examined and asked to complete a self-administered questionnaire regarding disabilities, relationships, education, as well as medical and economic outcomes. Participants also answered the ten questions used in the Dermatology Life Quality Index modified to ask 'over the last week', 'over the last year' and 'over your lifetime with psoriasis'. Survey responses were compared amongst the three patient groups based on BMI (normal, overweight, obese). RESULTS: Patients with elevated BMI were more likely to rate their general health lower (P < 0.001), believe that psoriasis caused their weight gain (P = 0.014), experience sleep problems over their lifetime (P = 0.016), hide their psoriasis over their lifetime (P = 0.010), have their self-confidence affected by their psoriasis over their lifetime (P = 0.011) and avoid common activities over their lifetime (P = 0.012). CONCLUSION: There are long-term negative effects of elevated BMI that impose additional burdens on psoriasis patients, including impairments in sleep quality and increased social anxiety.

RESUMO

OBJECTIVES: Heme oxygenase-1 (HO-1) is contributed to odontoblast differentiation in human dental pulp cells (HDPCs). In this study, pachymic acid from mushroom Formitopsis niagra is examined to determine whether it affects pulpal inflammation and promotes odontogenesis via HO-1 gene expression. MATERIALS AND METHODS: The HDPCs were given H2O2 for inflammation. The anti-inflammatory character and odontoblast differentiation by pachymic acid were analyzed by Western blotting, alkaline phosphatase activity, and alizarin red S staining. To understand the mechanism of pachymic acid via HO-1 induction, the cells were treated with zinc protoporphyrin IX (ZnPP: HO-1 inhibitor). RESULTS: H2O2 induced pulp inflammation and disturbed odontoblast differentiation. However, the HDPCs treated with pachymic acid affected anti-inflammatory effect and induction of odontoblast differentiation through increasing HO-1 expression. In addition, pachymic acid has potent cytoprotection and mineralization under H2O2 treatment. Furthermore, pachymic acid significantly suppressed nuclear factor-kappa B (NF-κB) translocation into nucleus and induced NE-E2-related factor-2 (Nrf2) translocation into nucleus. Overall, NF-κB and Nrf2 translocation were regulated by the HO-1 pathway. CONCLUSIONS: The pachymic acid showed anti-inflammatory function and odontoblast differentiation via HO-1 pathway. These results suggested that pachymic acid may be applicable for prevention of oral inflammation or to improve dentin mineralization against several stresses.

RESUMO

BACKGROUND AND PURPOSE: Some patients develop major neurological complications after carotid revascularization procedures, despite the lack of new infarcts or classical hyperperfusion syndrome. METHODS: In four patients who developed major neurological deficits after carotid revascularization procedures, but without evidence of new ischemic infarcts or hyperperfusion, we performed post-procedural MRI [diffusion-weighted image (DWI), perfusion-weighted image (PWI), pre-and post-contrast fluid-attenuated inversion recovery (FLAIR) image] immediately after and 1 day after the procedure. RESULTS: Post-gadolinium FLAIR images on 1 day after the procedures showed prominent leptomeningeal enhancements in the revascularized hemispheres. These radiological findings disappeared on follow-up FLAIR images accompanied by the clinical improvement over the following several days after the procedures. CONCLUSION: Reperfusion syndrome may be associated with transient severe neurological deficits after carotid revascularization in patients without new ischemic events or classical hyperperfusion syndrome.

RESUMO

The treatment of oropharyngeal squamous cell carcinoma (OSCC) remains controversial. This study reviews the authors' experience of treating OSCC, evaluates the oncologic outcome and assesses the factors affecting local/regional recurrence. A retrospective analysis of 110 consecutive OSCC patients treated primarily by surgery and/or postoperative radiotherapy was carried out. 82% of patients had advanced disease (stage III or IV). The 5-year overall survival and disease specific survival rates (DSSR) were 58% and 65%, respectively. The DSSR of the soft palate or posterior pharyngeal wall, tonsillar area, and base of tongue were 80%, 62%, and 51%, respectively (P<0.05). The 5-year DSSR according to the American Joint Committee on Cancer stages was 94% for early stage and 56% for advanced stage (P<0.05). The overall recurrence rate was 38% (42 patients). The most frequent site of recurrence was the neck (46%). Only 14% of patients with recurrences were treated successfully. Positive resection margins and the presence of pathologic lymph nodes influenced the recurrence at the primary lesion and in the neck, respectively, in a statistically significant manner. Surgery and postoperative radiotherapy provided a superior outcome in patients with advanced OSCC. A randomized study is required to assess the oncologic and functional superiority of surgery or chemoradiation.

RESUMO

BACKGROUND: Depressive symptoms are associated with poor prognosis in coronary artery disease, but there is a paucity of research on these symptoms in peripheral arterial disease (PAD). We examined the clinical correlates and 18-month course of depressive symptoms in PAD patients. METHODS: 166 patients with symptomatic lower-extremity PAD (39% women; M age=64.9 +/- 10 years) completed the 10-item Center for Epidemiological Studies Depression scale. A score > or =4 indicates clinically relevant depressive symptoms. Depressive symptoms were re-assessed at 6, 12, and 18 months follow-up. Ankle-brachial index (ABI) and treadmill walking distance were used to assess PAD severity. RESULTS: At baseline, depressive symptoms (CES-D > or =4) were present in 16% of the patients. Depressed patients performed worse regarding pain free (p=0.003) and maximum (p=0.005) walking distance. After adjusting for age, sex, education, ABI, psychotropic medication use, cardiovascular risk factors, and comorbidity, depressive symptoms remained stable in initially depressed patients. Using mixed modelling, three subgroups were identified in the total sample. The majority of PAD patients did not have depressive symptoms (58%), but there were two groups who persistently experienced either subclinical (27%) or clinically manifest (15%) depressive symptoms. LIMITATIONS: Only baseline data of ABI and treadmill walking performance were available. CONCLUSIONS: Depressive symptomatology was present in a substantial number of PAD patients, tended to be stable, and was associated with reduced walking distance. These apparently evident results are overlooked thus far in this patient group and deserve further attention in research and clinical care.

RESUMO

OBJECTIVE: We report our surgical treatment results of abdominal aortic aneurysm (AAA) in Behçet's disease patient. MATERIALS AND METHODS: Between September 1998 and June 2006, the authors have performed 21 procedures for AAA in 12 patients with Behçet's disease. Male to female sex ratio was 3:1 and mean age was 34 years old. Behçet's disease was diagnosed clinically using criteria of International Study Group for Behçet's Disease (1990). Retrospective analysis was made. RESULTS: There were six infrarenal, five suprarenal, and one double (suprarenal and infrarenal)AAA. Six graft interposition, six patch closure, and one stent-graft insertion were performed (one graft interposition and one patch closure were simultaneously performed for double AAA). Eight recurrent aneurysms were noted in six (50%) patients. Four stent-graft insertion, two patch closures, one graft interposition and one explothoracotomy only were performed for recurrent aneurysms. Overall recurrence rate of 21 procedures was 38.1%; 14.3% for graft interposition, 62.5% for patch closure, and 40% for stent-graft insertion. CONCLUSION: Though the resection and graft interposition is technically difficult in many occasions, it should be considered as the procedure of choice for abdominal aortic aneurysm in Behçet's disease. Endovascular interventions may be one of the treatment modality but the result needs further long-term follow-up.

RESUMO

BACKGROUND: Psychological stress and negative mood have been related to increased vulnerability to influenza-like illness (ILI). This prospective study re-evaluated the predictive value of perceived stress for self-reported ILI. We additionally explored the role of the negative affectivity and social inhibition traits. METHODS: In this study, 5,404 respondents from the general population were assessed in terms of perceived stress, personality, and control variables (vaccination, vitamin use, exercise, etc.). ILI were registered weekly using self-report measures during a follow-up period of four weeks. RESULTS: Multivariable logistic regression analysis on ILI was performed to test the predictive power of stress and personality. In this model, negative affectivity (OR = 1.05, p = 0.009), social inhibition (OR = 0.97, p = 0.011), and perceived stress (OR = 1.03, p = 0.048) predicted ILI reporting. Having a history of asthma (OR = 2.33, p = < 0.0001) was also associated with ILI reporting. Older age was associated with less self-reported ILI (OR = 0.98, P = 0.017). CONCLUSION: Elderly and socially inhibited persons tend to report less ILI as compared to their younger and less socially inhibited counterparts. In contrast, asthma, trait negative affectivity, and perceived stress were associated with higher self-report of ILI. Our results demonstrate the importance of including trait markers in future studies examining the relation between stress and self-report symptom measures.

RESUMO

BACKGROUND: Dysfunctional parenting styles are associated with poor mental and physical health. The 10-item Remembered Relationship with Parents (RRP(10)) scale retrospectively assesses Alienation (dysfunctional communication and intimacy) and Control (overprotection by parents), with an emphasis on deficiencies in empathic parenting. We examined the 2-factor structure of the RRP(10) and its relationship with adult depression. METHODS: 664 respondents from the general population (48% men, mean age 54.6+/-14.2 years) completed the RRP(10), Parental Bonding Instrument (PBI), and Beck Depression Inventory. RESULTS: The Alienation and Control dimensions of the RRP(10) displayed a sound factor structure, good internal consistency (Cronbach's alpha=0.83-0.86), and convergent validity against the PBI scales. No significant gender differences were found on the RRP(10) scales. Stratifying by RRP(10) dimensions showed that respondents high in Alienation and Control, for both father (33.3% vs. 14.5%, p<0.0001) and mother (42% vs. 12.9%, p<0.0001) items, experienced the highest levels of depressive symptoms compared with respondents low in Alienation and Control. While scoring high on Alienation or Control alone was also significantly and independently associated with depressive symptoms, scoring high on both Alienation and Control was most strongly connected with depressive symptoms for both father (OR=2.48, p<0.004) and mother (OR=5.34, p<0.0001) items. LIMITATIONS: Cross-sectional study design. CONCLUSIONS: The RRP(10) is a reliable and valid measure of remembered parental Alienation and Control. High Alienation and Control were independently related to increased risk of depressive symptoms. Given the brevity of the RRP(10), it can easily be used in epidemiological/clinical research on the link between the remembered relationship with parents and mental/physical health.

RESUMO

Oncolytic adenoviral vectors are currently being developed as biologic anticancer agents. Coupling the lytic function of an oncolytic adenovirus (Ad) with its ability as a transgene delivery system represents a powerful extension of this methodology. A clear advantage is the amplification of a therapeutic gene, as replicating vectors would be able to infect and deliver the gene of interest to neighboring cells. Granulocyte-macrophage colony-stimulating factor (GM-CSF) is one of the most potent stimulators of a specific and long-lasting antitumor immunity and its important role in the maturation of antigen-presenting cells to induce T-cell activation has been well documented. Similarly, the B7 family has also been shown to play an integral role in mediating an antitumor response. Most tumor cells, however, lack the expression of these costimulatory molecules on their surface, thus escaping immune system recognition. To increase the antitumor effect of an oncolytic Ad, we have generated an E1B 55 kDa-deleted oncolytic adenoviral vector, YKL-GB, that expresses both GM-CSF and B7-1. The therapeutic efficacy of YKL-GB Ad was evaluated in immunocompetent mice bearing murine melanoma B16-F10 tumors. Significant inhibition of tumor growth was seen in mice treated with YKL-GB compared to those treated with the analogous vector, YKL-1. Moreover, YKL-GB oncolytic Ad demonstrated enhanced antitumor activity and higher incidences of tumor regression compared to a replication-incompetent Ad, dl-GB, which coexpresses GM-CSF and B7-1. Localized GM-CSF and B7-1 gene transfer also conferred long-lasting immunity against a tumor re-challenge. To establish that the observed antitumor effect is associated with the generation of a tumor-specific immune response, we carried out interferon-gamma enzyme-linked immune spot assay. We observed that YKL-GB induced significantly higher immune cell activation than YKL-1. Furthermore, immunohistochemical studies demonstrated robust dendritic cells and CD4(+)/CD8(+) T-cell infiltration in these mice compared to the YKL-1-treated groups. In agreement with these results, splenocytes from tumor-bearing mice treated with YKL-GB expressed high levels of the costimulatory and activation molecules. These findings demonstrate the effectiveness of enhancing the immune response against tumors with an oncolytic Ad expressing both GM-CSF and B7-1 and provide a potential therapeutic strategy for the management of neoplasia.
