Smile—It's in your blood!

Emotions and feelings are the bricks of our social life and yet we often forget that they have a significant impact on our physical wellbeing. Indeed, a growing number of studies have shown that both an imbalanced or improved emotional state can significantly influence the way our immune system responds. In this commentary, we have summarized the most recent studies on the effects of different types of emotional states on the immune system and we have also explored the effects of mood modulator approaches on the immune response. We hope this commentary will prompt scientists and clinicians to think about the therapeutic value and potential of emotions and feelings in immune-related diseases. At the same time, we think that this commentary will shed some light on the scientific truth behind the very famous expression “It's in my blood” when we talk about feelings and personality.     

Nursing profession and nurses' contribution to nursing education as seen through students' eyes: A qualitative study

The behavior of clinical instructors, as observed by students, deeply influences their professional development. When instructors behave unprofessionally, they risk undermining the professional growth students gain from their clinical placement experience. Clinical instructors need to be aware of how their behavior can affect the students' learning process and the contributions they make to clinical nursing education. A qualitative study was performed to describe the nursing profession as perceived by students who observed their clinical instructors' behaviors during the clinical experience. In‐depth interviews of nursing students were conducted until data saturation was attained. Sixteen interviews were analyzed using an inductive content analysis methodology. The nursing profession was described by the participants through five themes as follows: the helping relationship, technical role, professional growth, working group, and contradictions and conflicts. Several examples of unprofessional behaviors on the part of the clinical instructors were reported by the respondents. The nursing profession, as perceived by nursing students, does not always reflect their expectations and their ideas related to professionalism. Universities and schools of nursing should ascertain that clinical instructors are prepared to educate students. Faculty should clearly state to students what they can expect from the clinical experience, namely, preparing students to face real working environments that do not always reflect educational philosophies.     

Favorable cardiovascular risk profile and 10-year coronary heart disease incidence in women and men: results from the Progetto CUORE.

BACKGROUND: Cardiovascular risk factor research has recently broadened its focus based on new data indicating the benefits of low risk, i.e. favorable levels of all major risk factors. The aims of this study were to assess further the relation of low risk to coronary heart disease risk, and implications for prevention. DESIGN: We conducted a prospective population-based Italian study, of 7438 men and 13 009 women aged 35-69 years, with a mean follow-up of 10.4 years and validated first coronary events. METHODS: Baseline coronary heart disease risk was classified into three categories: low risk; unfavorable but not high risk; and high risk. To analyze the relation of these risk profiles to coronary heart disease incidence, age-adjusted, sex-averaged coronary heart disease incidence was calculated for persons free of coronary heart disease and stroke, stratified as baseline low risk, unfavorable but not high risk or high risk. To assess the independent relationship of individual risk factors to coronary heart disease incidence, multivariate proportional hazards models were computed for combinations of risk factors. RESULTS: Only 2.7% of participants met low risk criteria; 81.4% were high risk. Age-adjusted coronary heart disease incidence for the whole cohort was 37.1 out of 10000 person-years (men 59.0; women 15.3). No coronary heart disease events occurred in low-risk men, only two in low-risk women. For women and men who were not high risk, the age-sex standardized coronary heart disease rate was 62% lower than for high-risk participants. Blood pressure, need for antihypertensive medication, smoking, hyperglycemia, diabetes, total and high-density lipoprotein cholesterol were independently related to coronary heart disease risk. CONCLUSIONS: Favorable levels of all modifiable readily measured risk factors - rare among Italian adults - assure minimal coronary heart disease risk. Population-wide prevention is needed, especially improved lifestyles, to increase the proportion of the population at low risk.     

The additive prognostic value of restrictive pattern and dipyridamole-induced contractile reserve in idiopathic dilated cardiomyopathy

BACKGROUND: Diastolic dysfunction and lack of contractile reserve are unfavorable prognostic predictors in patients with dilated cardiomyopathy (DCM). AIMS: This study aims to assess whether diastolic dysfunction and lack of dipyridamole-induced contractile reserve were additive predictors of poor outcome in patients with DCM. METHODS: A total of 116 patients with DCM and ejection fraction (EF<35%) were studied by dipyridamole echo (0.84 mg/kg over 10 min). At rest, a restrictive filling pattern was defined as: E/A ratio >2 and an E-wave deceleration time of <140 ms on transmitral flow velocity profile. RESULTS: Rest wall motion score index (WMSI) was 2.2+/-0.3 and decreased to 1.9+/-0.41 after dipyridamole (p<0.001). During follow-up (median 26.5 months), 22 cardiac deaths occurred. At multivariate analysis, dipyridamole-induced contractile reserve yielded significant incremental prognostic value (RR=0.275, p<0.006) over NYHA class (RR=1.971, p<0.03), angiotensin-converting enzyme inhibitor therapy (RR=0.173, p<0.001), and left ventricular end-diastolic diameter (RR=1.131, p<0.001). The worst prognostic combination was the presence of restrictive pattern at rest and the absence of contractile reserve (deltaWMSI<0.15). CONCLUSION: In patients with DCM, the ominous combination of restrictive transmitral flow pattern and lack of contractile reserve during dipyridamole stress predicts an unfavourable outcome.     

Correlates of hepatitis B among patients with mental illness in Brazil

Objective

To assess correlates of hepatitis B among adults with mental illness under care in Brazil.

Method

Cross-sectional national multicenter study of 2206 patients with mental illnesses randomly selected from 26 public mental health services. Sociodemographic and behavioral data were obtained from face-to-face interviews and psychiatric diagnoses from medical charts. Serology testing was conducted, and prevalence rate ratios were estimated by log-binomial regression.

Results

The weighted prevalence rates of current hepatitis B virus (HBV) infection (HBsAg +) and previous HBV exposure (anti-HBc +) were 2.0% [95% confidence interval (CI): 1.5%–2.7%] and 17.1% (95% CI: 16.0%–19.0%), respectively. Correlates of HBsAg + included male gender, younger age (18–29 years), unstable place of residence, intellectual disability, main psychiatric diagnosis of dementia, presence of other medical comorbitidy, use of alcohol/drugs during sex, more than one sexual partner and use of cocaine. Correlates of anti-HBc + included male gender, older age (≥ 30 years), black skin color, lower education, unstable place of residence, currently hospitalized, intellectual disability, history of any sexually transmitted disease or syphilis, poor HIV knowledge, history of imprisonment and sexual violence.

Conclusions

Hepatitis B is an important comorbidity among psychiatric patients in Brazil. Screening for HBV, effective prevention and intervention strategies, including universal HBV immunization, should be routine practices in these mental health services.     

“I have got something positive out of this situation”: psychological benefits of caregiving in relatives of young people with muscular dystrophy

This paper focuses on the psychological benefits of caregiving in key relatives of patients with muscular dystrophies (MD), a group of rare diseases characterized by progressive weakness and restriction of the patient’s functional abilities. We describe whether relatives perceived caregiving to be a positive experience and test whether relatives’ perceptions vary in relation to their view of the patient as a valued person, the degree of involvement in care, and the level of support provided by social network and professionals. The study sample included 502 key relatives of patients aged 4–25 years, suffering from Duchenne, Becker, or limb-girdle MD, in treatment for at least 6 months to one of the eight participating centers, living with at least one relative aged 18–80 years. Of key relatives, 88 % stated that they had gotten something positive out of the situation, 96 % considered their patients to be sensitive, and 94 % viewed their patients as talented. Positive aspects of caregiving were more recognized by key relatives who were more convinced that the patient was sensitive and who perceived that they received higher level of professional help and psychological social support. These results suggest that most key relatives consider that their caregiving experience has had a positive impact on their lives, despite the practical difficulties of caring for patients with MD. Professionals should help relatives to identify the benefits of caregiving without denying its difficulties. Clinicians themselves should develop positive attitudes towards family involvement in the care of patients with long-term diseases.     

Current management of late onset neonatal bacterial sepsis in five European countries

Late onset neonatal sepsis (LOS) has a high mortality and the optimal management is poorly defined. We aimed to evaluate new expert panel-derived criteria to define LOS and characterize the current management and antibiotic susceptibility of LOS-causing organisms in Europe. A prospective observational study enrolled infants aged 4 to 90 days in five European countries. Clinical and laboratory findings as well as empiric treatment were recorded and patients were followed until the end of antibiotic therapy. Failure was defined as a change of primary antibiotic, no resolution of clinical signs, appearance of new signs/pathogens or death. Antibiotic therapy was considered appropriate if the organism was susceptible to at least one empiric antibiotic. 113 infants (median age 14 days, 62 % ≤1500 g) were recruited; 61 % were culture proven cases (28 CoNS, 24 Enterobacteriaceae, 11 other Gram-positives and 6 Gram-negative non-fermentative organisms). The predictive value of the expert-panel criteria to identify patients with a culture proven LOS was 61 % (95 % CI 52 % to 70 %). Around one third of Enterobacteriaceae were resistant to ampicillin + or cefotaxime + gentamicin but only 10 % to meropenem. Empiric treatment contained a total of 43 different antibiotic regimens. All-cause mortality was 8 % with an additional 45 % classified as failure of empiric therapy, mainly due to change of primary antibiotics (42/60). Conclusions: The expert panel—derived diagnostic criteria performed well identifying a high rate of culture proven sepsis. Current management of LOS in Europe is extremely variable suggesting an urgent need of evidence-based guidelines.     

Relapse in medulloblastoma: what can be done after abandoning high-dose chemotherapy? A mono-institutional experience

Purpose

We retrospectively report strategies used for medulloblastoma patients progressing after craniospinal irradiation where we aimed for: symptom control, a satisfactory quality of life, accrual in phase 1–2 trials, when available, and the first two conditions could no longer be satisfied by already experienced second-line strategies.

Methods

Surgery was used in cases of doubtful relapse or when only one site was affected. Radiotherapy was given whenever possible, especially to relieve symptoms. The main chemotherapy regimens were oral temozolomide/etoposide, intravenous (iv.) cisplatin/etoposide, iv. gemcitabine/oxaliplatin, an oral sonic hedgehog pathway inhibitor and oral melphalan.

Results

Between 1998 and 2011, we treated 18 patients relapsed after median 20 months. Nine had relapsed locally, four had dissemination, three single metastases, and two had one synchronous local and metastatic recurrence. Responses to chemotherapy were seen in 32 % of cases. The median hospital stay for treatments/complications was 19 days. The 1- and 3-year progression-free survival (PFS) rates were 28?±?10 % and 0 %, respectively, for OS, they were 44?±?12 % and 22?±?10 % but no patient was cured. The median PFS after a first relapse was 7 months (range 1–29); the median OS was 7 months (range 4–44). No patients died due to treatment toxicity. Late recurrence (more than 1–2 years after diagnosis) and involvement of single sites were favorable prognostic factors.

Conclusions

Without succeeding in patients cure, we ensured them further treatment with short hospital stay thus affording low personal and social costs. The chances of cure may emerge from tailored therapies according to genetic stratification.     

Multiple mechanisms of telomere maintenance exist and differentially affect clinical outcome in diffuse malignant peritoneal mesothelioma

PURPOSE: This study aims to investigate the prevalence of the two known telomere maintenance mechanisms, telomerase activity (TA) and alternative lengthening of telomeres (ALT), and to assess their prognostic relevance in diffuse malignant peritoneal mesothelioma (DMPM). EXPERIMENTAL DESIGN: In 44 DMPM specimens obtained from 38 patients, TA was determined using the telomeric repeat amplification protocol and ALT was detected by assaying ALT-associated promyelocytic leukemia nuclear bodies. The prognostic significance of telomere maintenance mechanisms was analyzed by Cox regression in the overall series and in a subset of 29 patients who underwent a uniform treatment regimen consisting of cytoreductive surgery and hyperthermic i.p. chemotherapy. RESULTS: Telomere maintenance mechanisms were detectable in 86.4% of DMPM: ALT or TA alone was found in 18.2% or 63.6% of lesions, respectively, whereas two cases (4.6%) were ALT+/TA+. TA and ALT proved to be inversely associated (P = 0.002). In the overall series, TA was prognostic for 4-year relapse (TA+ versus TA-, hazard ratio, 3.30; 95% confidence interval, 1.23-8.86; P = 0.018) and cancer-related death (TA+ versus TA-, hazard ratio, 3.56; 95% confidence interval, 1.03-12.51; P = 0.045), whereas ALT failed to significantly affect clinical outcome. These results held true also in the subset of patients submitted to uniform treatment with cytoreductive surgery and hyperthermic i.p. chemotherapy. CONCLUSIONS: Our results indicate that both known telomere maintenance mechanisms, TA and ALT, are present in DMPM and differentially affect patient prognosis.
