Structure and expression of a polyubiquitin gene from the crustacean Artemia

We have characterized two polyubiquitin genes from the crustacean Artemia franciscana. One of them, Ubi1, has nine ubiquitin units and an intron of a minimum size of 3.5 kb that ends 7 bp before the initiator ATG. The 5' end of the transcript from this gene has been identified by anchored PCR. The existence of the other gene (Ubi2) was inferred from several cDNA clones that differ from Ubi1 in the C-terminal extension and in the 3' untranslated region as well as in the nucleotide sequence of the coding region. We find two transcripts of ubiquitin genes, of 2.7 and 3.3 kb. Hybridization of RNA blots with an oligonucleotide specific for Ubi2 gene demonstrates that this gene codes for the 3.3 kb transcript. Ubiquitin messenger RNAs are present in the dormant embryos and their steady-state levels are maximum at 8 h after resumption of development, declining thereafter. The Ubi2 gene transcripts are less abundant but its proportion in relation to the other transcript does not vary with development.

Hexavalent vaccines: characteristics of available products and practical considerations from a panel of Italian experts

Combination vaccines represent a valuable technological innovation in the field of infectious disease prevention and public health, because of their great health and economic value from the individual, societal, and healthcare system perspectives. In order to increase parents' and healthcare professionals' confidence in the vaccination programs and maintain their benefits to society, more information about the benefits of innovative vaccination tools such as combination vaccines is needed. Purpose of this work is an examination of available hexavalent vaccines, that protect against Diphtheria, Tetanus, Pertussis, Poliomyelitis, Hepatitis B and Haemophilus influenzae type b infections. From the epidemiological updates of vaccine preventable diseases to the vaccine development cycle, from the immunogenicity of antigenic components to the safety and co-administration with other vaccines, several aspects of available hexavalent vaccines are discussed and deepened. Also a number of practical considerations on schedules, age of employment, strategies for vaccination recovery, vaccination in at-risk births are issued, based on the recommendations of Italian Ministry of Health, Italian Society of Pharmacology (SIF), Italian Society for Pediatrics (SIP), Italian Federation of Family Paediatricians (FIMP) and Italian Society of Hygiene, Preventive Medicine and Public Health (SItI).

The Role of Dispositional Flow’s Dimensions in the Prediction of Intention to be Physically Active in Adolescents

Enmarcado en la teoría del flow, este estudio pretende a) comprobar las diferencias en las dimensiones del flow disposicional yen la intención futura de realizar actividad física (IF) según el nivel de AF y b) estudiar el papel predictivo de dichas dimensiones sobre la IF. La muestra estuvo compuesta por 1076 estudiantes de educación física y se segmentó según el nivel actual de AF. Los sujetos que mostraron mayores niveles de AF presentaron valores más elevados en todas las dimensiones. Los análisis de regresión por pasos indicaron que la experiencia autotélica se asoció con IF en todos los participantes. Además, en el grupo de baja actividad el equilibrio percibido entre el reto y la habilidad emergió como predictor mientras que en el grupo de alta actividad, tanto la sensación de control como la percepción de objetivos claros resultaron significativos en la explicación de la IF. Los resultados sugieren que la implementación en clases de EF de diferentes estrategias para mejorar la disposición a experimentar el flow, puede aumentar la IF.

Voluntary termination of pregnancy: An opportunity for Measles, Mumps and Rubella vaccination in an Italian healthcare local unit

In Italy, the National Plan for the Elimination of Measles and Congenital Rubella 2010-15 suggests offering Measles, Mumps and Rubella (MMR) vaccination to susceptible women who underwent voluntary termination of pregnancy (VTP) In Rome, S. Eugenio Hospital is one of the structures where VTP is practised in an Operative Unit called "Family Planning" The primary goal of this study was to estimate the prevalence of susceptibility to rubella, using IgG and IgM immunoassays, among women accessing VTP and to offering MMR vaccination to susceptible women. Secondarily, this study evaluated acceptance of the vaccination offer From 2013 to 2015, data were collected from 1513 voluntary termination of pregnancy (VTP) cases The results show a significant increase of 5 percent in susceptibility prevalence in the target group from 13.6% in 2013 and 2014 to 18.4% in 2015 The association between rubella susceptibility and age was statistically significant (p<0.01) Throughout the entire period, acceptance of the vaccine proposal was 19% (45/232) among susceptible women; 58% (135/232) refused the vaccine and 23% (52/232) took time to think about it This study shows an increase of 5 percent in the prevalence of rubella susceptibility over two years. This result is worrying, even considering the short span of the data collection The rate of acceptance of vaccination is unsatisfactory considering the possibility of future pregnancies This issue deserves continued action, which, going forward, might transform a "project" into a shared strategy as part of a wider network with the goal of aligning Italy with international recommendations.

Validación de la versión española del cuestionario “Actitudes de los alumnos hacia la integración en educación física (CAIPE-R)”

La Educación Física (EF) se muestra, a priori, como un área idónea para trabajar intervenciones educativas para facilitar la inclusión de alumnos con discapacidad, siendo las actitudes de los compañeros sin discapacidad determinantes en este proceso. Este estudio presenta el análisis de validez y fiabilidad de la versión española del cuestionario Children Attitude Integrated Physical Education- Revised (CAIPE-R; Block, 1995). Para ello se utilizó una muestra de 222 alumnos de EF en Educación Secundaria Obligatoria de centros educativos de Madrid, compuesta por 117 varones y 105 mujeres, con edades comprendidas entre los 12 y los 18 años (M=14.07; SD=1.31). Los resultados muestran la adecuada fiabilidad del cuestionario y la validez del constructo, con un buen ajuste al modelo. La escala adaptada arrojó una reducción a 10 ítems, obteniendo una consistencia interna general por encima de 0.70, salvo en los ítems 2 y 8 de la escala general y el ítem 9 de la escala específica. El estudio concluye que la versión muestra una validez y fiabilidad adecuadas para detectar las actitudes hacia la inclusion de compañeros con discapacidad en EF en el contexto español.

The Effects of a Physical Education Intervention to Support the Satisfaction of Basic Psychological Needs on the Motivation and Intentions to be Physically Active

The aim of the study was to investigate the effects of an intervention to support the basic psychological needs on the satisfaction of these needs, intrinsic motivation, intention to be physically active and some enjoyment-related outcomes in Physical Education. The present study incorporated strategies presented by Standage and Ryan (2012) in a previous study. A quasi-experimental study was conducted with two groups (n_experimental = 30; n_control = 23) of 2nd year Secondary Education students aged between 13 and 15 (M = 13.35, SD = .62) by delivering 24 physical education classes. The teacher in the experimental group underwent prior and continual training. The results revealed that the students from the experimental group showed a significant increase in the perception of autonomy and competence. Furthermore, the experimental group showed a greater perception than the control group in the enjoyment related to learning and contents. These results provide information about the efficacy of an intervention programme based on the strategies presented by Standage and Ryan (2012) to foster satisfaction of basic psychological needs and facilitate support for basic psychological needs to promote the development of positive learning-related outcomes.

Effects of extremely low frequency electromagnetic fields on in-vitro cellular cultures HeLa and CHO

This paper presents the cellular proliferation effects of the exposure to extremely low frequency electromagnetic fields (ELF-EMF) on in-vitro cellular cultures HeLa and CHO. Through the magnetic stimulation system (MSS) the cells were exposed to magnetic fields with sinusoidal waveform at 50 Hz; initially for 40 minutes at intensities of 0.4 mT, 1.4 mT, 2.13 mT, 2.49 mT and 2.53 mT in parallel and perpendicular directions to the culture plates. Subsequently, the repetitive electromagnetic field (rEMF) was applied to 2.49 mT in parallel direction (for 40 minutes every twelve hours during 4 days) with which the highest cellular proliferation rate was obtained at 66.6 %. The results show a greater effect on proliferation in radiated cell lines, particularly in the application of rEMF a greater effect of ELF-EMF was observed in the proliferation rate of HeLa cells than in CHO cells, in contrast to the respective control cells. These results supported by other studies serve as a reference in the search for alternatives for the treatment of cervical cancer and the maintenance and preservation of cell lines.

Frequently asked questions on seven rare adverse events following immunization

Routine mass immunization programs have contributed greatly to the control of infectious diseases and to the improvement of the health of populations. Over the last decades, the rise of antivaccination movements has threatened the advances made in this field to the point that vaccination coverage rates have decreased and outbreaks of vaccine-preventable diseases have resurfaced. One of the critical points of the immunization debate revolves around the level of risk attributable to vaccination, namely the possibility of experiencing serious and possibly irreversible adverse events. Unfortunately, the knowledge about adverse events, especially rare ones, is usually incomplete at best and the attribution of a causal relationship with vaccinations is subject to significant uncertainties. The aim of this paper is to provide a narrative review of seven rare or very rare adverse events: hypotonic hyporesponsive episode, multiple sclerosis, apnea in preterm newborns, Guillain-Barré syndrome, vasculitides, arthritis/ arthralgia, immune thrombocytopenic purpura. We have selected these adverse events based on our experience of questions asked by health care workers involved in vaccination services. Information on the chosen adverse events was retrieved from Medline using appropriate search terms. The review is in the form of questions and answers for each adverse event, with a view to providing useful and actionable concepts while not ignoring the uncertainties that remain. We also highlight in the conclusion possible future improvements to adverse event detection and assessment that could help identify individuals at higher risk against the probable future backdrop of ever-greater abandonment of compulsory vaccination policies.

Incidence and predictors of stroke during the index event in an ethnically diverse Takotsubo cardiomyopathy population

Takotsubo cardiomyopathy (TTS) is a peculiar clinical condition often affecting postmenopausal women after a stressful trigger. The underlying mechanisms have not been completely elucidated but several hypotheses have been advanced, with catecholamine cardiotoxicity, microvascular dysfunction and coronary artery spasm each suggested to play a role. The incidence of stroke after TTS appears to range from 0% to 7.7%, and interestingly TTS has been described as both a cause and a complication of stroke. We sought to assess the incidence and predictors of stroke during the index event (peri-index event stroke) in a heterogeneous TTS population. We conducted a retrospective descriptive study reviewing patients who were discharged with a diagnosis of TTS from the Einstein Medical Center, Philadelphia, PA and Danbury Hospital, Danbury, CT in the period between 2003 and 2014. A total of Incidence and predictors of stroke during the index event in an ethnically diverse Takotsubo cardiomyopathy population 206 patients met the modified Mayo Clinic criteria and were included in the study. The patients' overall mean age was 67.8 years; 87% (n=179) were females and 25% (n=53) were African Americans. The following incidence rates were found: stroke 7%, in-hospital heart failure 26.7%, and in-hospital death 7%. On multivariate analysis independent predictors (expressed as odds ratios with 95% confidence intervals) of periindex event stroke were: i) African American race (OR 3.2, 95% CI 1.2-10.2, p=0.048); ii) hypertension (OR 10.5, 95% CI 1.3-88, p=0.03). ACE inhibitor use was a protective factor for developing peri-index event stroke (OR 0.15, 95% CI 0.04-0.5, p=0.001). There was a trend towards dual antiplatelet therapy (DAPT) being protective for stroke (OR 0.3, 95% CI 0.05-1.1, p=0.08). The incidence of peri-index event stroke was 7%. African American race and hypertension were found to be independent predictors of peri-index event stroke. Prospective clinical trials are needed to confirm these findings and to better determine the impact of hypertension as a risk factor for stroke and to assess the role of DAPT in preventing it.

Disability, support and long-term social care of an elderly Spanish population, 2008-2009: an epidemiologic analysis

BACKGROUND

Though poorly known, relationships between disability, need of help (dependency) and use of social services are crucial aspects of public health. The objective of this study was to describe the links between disability, officially assessed dependency, and social service use by an industrial population, and identify areas of inequity.

METHODS

We took advantage of a door-to-door survey conducted in the Cinco Villas district, Spain, in 2008-2009, which provided data on disability, morbidity, and service use among 1216 residents aged ≥50 years, and officially assessed dependency under the 2006 Dependency Act (OAD). Using logistic regression, we combined data collected at homes/residences on 625 disability screened-positive participants, and administrative information on degree of OAD and benefits at date of visit.

RESULTS

Based on 163 disabled persons, the prevalence of residential/community-care users was 13.4% overall, with 6.0% being market-provided, 2.5% supported by the 2006 Act, and 4.9% supported by other public funds. Of 111 OAD applicants, 30 had been assigned an OAD degree; in 29 cases this was the highest OAD degree, with 12 receiving direct support for residential care and 17 receiving home care. Compared to unassessed dependency, the highest OAD degree was linked to residential care (OR and 95% CI) 12.13 (3.86-38.16), declared non-professional care 10.99 (1.28-94.53), and publicly-funded, non-professional care 26.30 (3.36-205.88). In contrast, 43 persons, 58% of the severely/extremely disabled, community-dwelling sample population, 81% of whom were homebound, including 10 persons with OAD but no implemented service plan, made no use of any service, and of these, 40% lacked a non-professional carer.

CONCLUSIONS

Formal service use in the Cinco Villas district attained ratios observed for established welfare systems but the publicly-funded proportion was lower. The 2006 Act had a modest, albeit significant, impact on support for non-professional carers and residential care, coexisting with a high prevalence of non-use of social services by severely disabled persons.

Nosocomial rotavirus infection: An up to date evaluation of European studies

Rotavirus (RV) is worldwide considered as the most important viral agent of acute gastroenteritis in children less than 5 y. Since 2006, the availability of anti-RV vaccines has deeply modified the incidence and economic burden of RV infection. In Europe, some countries have introduced an anti-RV vaccination program in the last 10 y. Although community acquired RV (CARV) disease is the most studied condition of RV infection, recently some authors have highlighted the importance of nosocomial RV (nRV) disease as an emerging public health issue. The aim of this review is to summarize the epidemiology of both CARV and nRV, in order to discuss the difficulty of a clear evaluation of the burden of the disease in absence of comparable data. In particular, we focused our attention to European studies regarding nRV in terms of divergences related to definition, report of incidence rate and methodological issues.

Measuring and benchmarking the quality of two different organizational ways in delivering infant vaccination

The aim of this study was the quality of service evaluation of two different organizational ways in delivering infant vaccination according to a Regional Vaccination Plan. Eleven vaccination centres were selected in two Local Health Units (ASLs) belonging to the Regional Health Service of the Lazio Region, Italy. The services offering paediatric vaccinations for children under three years of age, delivered without an appointment (VACP) or with the need for an appointment (VACL), were investigated. The quality aspects under evaluation were communicational efficiency, organisational efficiency and comfort. Subjective data were collected from different stakeholders and involve the elicitation of best and worst feasible performance conditions for the ASLs when delivering VACP/VACL services. Objective data consists in the observation of current performances of the selected vaccination centres. Quality scorecards were obtained from the combination of all data. Benchmarking between VACP and VACL, i.e., two different organisational ways in delivering infant vaccination, can be performed as a result of the probabilistic meaning of the evaluated scores. An expert of vaccination services, i.e., a virtual combination of patients, doctors and nurses, claims the quality of service delivery of the ASLs under investigation with probability 78.03% and 69.67% for VACP and VACL, respectively. In other words, for short, the quality scores of the ASLs were 78.03% for VACP and 69.67% for VACL. Furthermore our results show how to practically improve the current service delivery. The QuaVaTAR approach can result in improvements of the quality of the ASLs for the two different ways of delivering paediatric vaccinations in a simple and intuitive way.

Regular Exercise Throughout Pregnancy is Associated with a Shorter First Stage of Labor

Purpose.

The aim of the present study was to examine the influence of moderate physical exercise throughout pregnancy on the duration of labor stages.

Design.

Study was a randomized controlled trial.

Setting.

The study took place at Hospital Puerta de Hierro and Hospital Severo Ochoa in Madrid, Spain.

Subjects.

We examined 166 pregnant women (31.6 ± 3.8 years), and all had uncomplicated and singleton gestation. Of these 83 were allocated to the exercise group (EG) and 83 to the control group (CG).

Intervention.

Women from the EG participated in a physical conditioning program throughout pregnancy, which included 55- to 60-minute sessions, 3 days per week.

Measures.

Pregnancy outcomes were measured: duration of labor stages, gestational age, weight gain, type of delivery, birth weight, birth size, head circumference, Apgar score, pH of umbilical cord.

Analysis.

Student's unpaired t-tests and χ2 tests were used; p values of < .05 indicated statistical significance. Cohen's d was used to determine the effect size.

Results.

Significant differences were found in the duration of the first stage of labor (EG = 389.6 ± 347.64 minutes vs. CG = 515.72 ± 353.36 minutes; p = .02, effect size Cohen's d = .36). The second and third stages did not differ between the study groups.

Conclusion.

A physical exercise program during pregnancy is associated with a shorter first stage of labor. These results may have important relevance to public health.
