RISEinFAMILY project: the integration of families at neonatal intensive care units (NICUs) to empower them as primary caregivers: study protocol for a stepped wedge cluster controlled trial.

BACKGROUND: Family Integrated Care (FICare) has demonstrated positive outcomes for sick neonates and has alleviated the psychological burden faced by families. FICare involves structured training for professionals and caregivers along with the provision of resources to offer physical and psychological support to parents. However, FICare implementation has been primarily limited to developed countries. It remains crucial to assess the scalability of this model in overcoming social-cultural barriers and conduct a cost-effectiveness analysis. The RISEinFAMILY project aims to develop an adapted FICare model that can serve as the international standard for neonatal care, accommodating various cultural, architectural, and socio-economic contexts. METHODS: RISEinFAMILY is a pluri-cultural, stepped wedge cluster controlled trial conducted in Spain, Netherlands, the UK, Romania, Turkey, and Zambia. Eligible participants include infant-family dyads admitted to the Neonatal Intensive Care Unit (NICU) requiring specialised neonatal care for a minimum expected duration of 7 days, provided there are no comprehension barriers. Notably, this study will incorporate a value of implementation analysis on FICare, which can inform policy decisions regarding investment in implementation activities, even in situations with diverse data. DISCUSSION: This study aims to evaluate the scalability and adaptation of FICare across a broader range of geographical and sociocultural contexts and address its sustainability. Furthermore, it seeks to compare the RISEinFAMILY model with standard care, examining differences in short-term newborn outcomes, family mental health, and professional satisfaction.

Nasogastric enteral feeding tubes modulate preterm colonization in early life.

BACKGROUND: Preterm infants are generally fed through nasogastric enteral feeding tubes (NEFTs). The aim of this work was to evaluate the role of NEFTs in the initial colonization of the preterm gut and its evolution within the first 2 weeks after birth. METHODS: For this purpose, fecal and NEFT-derived samples from 30 preterm infants hospitalized in a neonatal intensive care unit (NICU) were collected from birth to the second week of life. Samples were cultivated in ten culture media, including three for the isolation of antibiotic-resistant microorganisms. RESULTS: Isolates (561) were identified by 16S ribosomal RNA gene sequencing. Although the first NEFTs inserted into the neonates after birth were rarely colonized, analysis of NEFTs and fecal samples over time revealed a significant increase in bacterial abundance, diversity, and detection frequency. Results showed a parallel colonization between time-matched NEFTs and fecal samples, suggesting an ongoing bidirectional transfer of bacteria from the neonatal gut to the NEFTs and vice versa. CONCLUSIONS: In short-term hospitalization, length is by far the determinant factor for the early colonization of preterm infants. As NEFT populations reflect the bacterial populations that are colonizing the preterm in a precise moment, their knowledge could be useful to prevent the dissemination of antibiotic-resistant strains. IMPACT: The hospital environment modulates preterm colonization immediately after birth. The colonization of preterm feces and NEFTs occurs in parallel. There is an ongoing bidirectional transfer of microorganisms from the neonatal gut to the NEFTs and vice versa. Bacterial communities inside NEFTs could act as reservoirs of antibiotic resistance genes. NEFT populations reflect the bacteria that are colonizing the preterm at a precise moment.

Serum adiponectin is associated with body composition and cognitive and psychological status in older adults living in long-term nursing homes.

Frailty is a geriatric syndrome characterized by decreasing functional reserves and increasing vulnerability to falls, injuries and declining health, leading to dependence upon caregivers. Frailty is associated not only with physical decline, but also with cognitive and psychological impairments in aging people. Higher serum adiponectin concentration has been linked to better performance on frailty measures but also to worse cognitive status. Nonetheless, several studies have proposed adiponectin as a frailty biomarker. To further delineate the relationship between adiponectin serum levels and frailty-related parameters, we studied a population of 112 long-term nursing home residents (aged 84.9 ±â€¯6.7) and analyzed their serum adiponectin levels in conjunction with frailty-related parameters including body composition, physical fitness, cognitive function, psychological parameters and quality of life. Frailty was assessed following the Fried Frailty Criteria, the Clinical Frailty Scale and the Tilburg Frailty Indicator. In women, higher serum adiponectin levels were associated with lower body weight, body mass index, body fat mass, fat mass/height2, lean mass, lean mass/height2 and smaller waist circumference and hip circumference (p < 0.05). In men, the association was positive (p < 0.05) between serum adiponectin and percentage of fat mass and negative between serum adiponectin and percentage of lean mass. Interestingly, in men, better cognitive function was inversely related to adiponectin (p < 0.05) while decreased anxiety was linked to a higher concentration of adiponectin in women (p < 0.05). According to the Tilburg Frailty Indicator, frail men had lower levels of adiponectin than those who were not frail (p < 0.05). Variables that predicted adiponectin concentration in multiple regression models were different for women and men. In women, lean mass and anxiety were independent negative predictors of blood adiponectin (ß = -0.363, p = 0.002; ß = -0.204, p = 0.067, respectively). In men, the Montreal Cognitive Assessment (MOCA) test was the only parameter to remain significant in the regression model (ß = -439, p = 0.015). The results of our study show that adiponectin is linked to body composition, cognitive function and anxiety in long-term nursing home residents with differential relationships by sex. Further studies should be conducted to determine whether adiponectin is a valid and reliable frailty biomarker.

Gold-decorated magnetic nanoparticles design for hyperthermia applications and as a potential platform for their surface-functionalization.

The integration of noble metal and magnetic nanoparticles with controlled structures that can couple various specific effects to the different nanocomposite in multifunctional nanosystems have been found interesting in the field of medicine. In this work, we show synthesis route to prepare small Au nanoparticles of sizes = 3.9 ± 0.2 nm attached to Fe3O4 nanoparticle cores ( = 49.2 ± 3.5 nm) in aqueous medium for potential application as a nano-heater. Remarkably, the resulted Au decorated PEI-Fe3O4 (Au@PEI-Fe3O4) nanoparticles are able to retain bulk magnetic moment MS = 82-84 Am2/kgFe3O4, with the Verwey transition observed at TV = 98 K. In addition, the in vitro cytotoxicity analysis of the nanosystem microglial BV2 cells showed high viability (>97.5%) to concentrate up to 100 µg/mL in comparison to the control samples. In vitro heating experiments on microglial BV2 cells under an ac magnetic field (H0 = 23.87 kA/m; f = 571 kHz) yielded specific power absorption (SPA) values of SPA = 43 ± 3 and 49 ± 1 µW/cell for PEI-Fe3O4 and Au@PEI-Fe3O4 NPs, respectively. These similar intracellular SPA values imply that functionalization of the magnetic particles with Au did not change the heating efficiency, providing at the same time a more flexible platform for multifunctional functionalization.

Obesity parameters, physical activity, and physical fitness are correlated with serum dipeptidyl peptidase IV activity in a healthy population.

OBJECTIVE: To determine whether obesity, physical fitness, and physical activity parameters are associated with the enzymatic activity of serum dipeptidyl peptidase IV (sDPPIV) in a sample of healthy women and men. DESIGN AND METHODS: We have correlated parameters of obesity, physical fitness, and physical activity with sDPPIV activity in 374 healthy subjects (age: 60.7 ± 6.9 years, body mass index: 26.1 ± 4.1 kg/m2). Enzymatic activity was analyzed using spectrofluorimetry, body composition was assessed by impedanciometry, physical fitness data were obtained using the Senior Fitness Test, and physical activity data were collected by accelerometer. Pearson's partial correlation analysis was applied to determine the relationship between DPPIV activity and the rest of parameters and significantly correlated variables were introduced into linear regression models to predict DPPIV. RESULTS: Serum DPPIV activity was negatively associated with obesity parameters such as body mass (r = -0.112), body mass index (BMI) (r = -0.147), waist circumference (r = -0.164), waist-to-hip ratio (-0.104), and percentage of fat mass (r = -0.185). Serum DPPIV activity was positively associated with cardiovascular fitness (r = 0.138), total amount of physical activity (r = 0.153), and time spent doing light exercise (r = 0.184). Regression models revealed sex differences in enzyme activity with overall activity higher in women than in men (ß = 0.437, p < 0.001). Further, percent fat mass was an independent negative predictor of DPPIV activity (ß = -0.184, p = 0.001). Serum DPPIV activity was positively predicted based on the amount of time spent doing light physical activity (ß = 0.167, p = 0.001). CONCLUSION: Our results demonstrate that sDPPIV activity is positively associated with healthier parameters regarding fatness, fitness and physical activity.

Chronic musculoskeletal pain in European older adults: Cross-national and gender differences.

BACKGROUND: In an ageing Europe, chronic pain is a major public health problem, but robust epidemiological data are scarce. This study aimed to analyse the prevalence of and factors associated with chronic musculoskeletal pain by gender in older adults of 14 European countries. METHODS: A cross-sectional study was performed from wave 5 of the Survey of Health, Ageing and Retirement in Europe (SHARE). The study included people ≥50 years residing in Austria, Belgium, Czech Republic, Denmark, Estonia, France, Germany, Italy, Luxembourg, the Netherlands, Slovenia, Spain, Sweden and Switzerland. Chronic pain was defined as being bothered by joint and/or back pain for the previous 6 months. Multivariable Poisson regression models with robust variance were performed to analyse prevalence ratio by covariates, stratified by sex. RESULTS: A total of 61,157 participants were included. Overall prevalence of chronic musculoskeletal pain was 35.7% (28.8-31.7), ranging from 18.6% (17.1-20.1) for Switzerland to 45.6% (43.3-47.8) for France. Prevalence was higher in women than in men: 41.3% (40.2-42.4) versus 29.1% (28.0-30.3). Chronic musculoskeletal pain was lower in men aged >75 years (PR = 0.82; 0.72-0.92) than the younger (50-59) group. Separated/divorced status presented opposite effects among men (PR = 0.85; 0.76-0.96) and women (PR = 1.12; 1.03-1.21) compared with married, and unemployment was a significant factor in men (PR = 1.21; 95% CI 1.02-1.43) compared with employed. CONCLUSIONS: Musculoskeletal pain in older European adults is very frequent, especially in women, with large differences depending on the country of residence. Health policy makers should prioritize strategies aimed at improving the prevention and management of chronic musculoskeletal pain in Europe. SIGNIFICANCE: This study provides epidemiological data of chronic musculoskeletal pain in older adults. Reported differences contribute to highlight the relevance of considering a gender perspective in chronic musculoskeletal pain research. Cross-national comparison also offers a map of differences that improves the knowledge of this chronic condition in Europe.

Magnetically responsive biopolymeric multilayer films for local hyperthermia.

We present a proof of concept on the use of thermomagnetic polymer films (TMFs) as heating devices for magnetic hyperthermia in vitro. The TMFs were prepared through spray assisted layer-by-layer assembly of polysaccharides and magnetic iron oxide nanoparticles, yielding an alternate magnetic-polymer multilayer structure. By applying a remote alternating magnetic field (AMF) (f = 180 kHz; H = 35 kA m-1) we increased the temperature of the TMFs in a thickness-dependent way, up to 12 °C within the first 5 minutes. To test our films as heating substrates for magnetic hyperthermia, a series of in vitro experiments were designed using human neuroblastoma SH-SY5Y cells, known by their tolerance to thermal stress. The application of two AMF cycles (30 minutes each) showed that the exogenous magnetic hyperthermia resulted in an 85% reduction of cell viability. This capacity of the TMFs of hyperthermia-mediated cell killing using a remote AMF opens new options for the treatment of small and superficial tumor lesions by means of remotely-triggered magnetic hyperthermia.

[Dental caries and early childhood development: a pilot study]. / Caries dental y desarrollo infantil temprano. Estudio piloto.

OBJECTIVE: To investigate the association between dental caries and early childhood development in 3-year-olds from Talca, Chile. METHOD: A pilot study with a convenience sample of 3-year-olds from Talca (n = 39) who attend public healthcare centers. Child development was measured by the Psychomotor Development Index (PDI), a screening tool used nationally among pre-school children to assess language development, fine motor skills and coordination areas. Dental caries prevalence was evaluated by decayed, missing, filled teeth (DFMT) and decayed, missing, filled tooth surfaces (DFMS) ceo-d and ceo-s indexes. The children were divided into two groups according to the PDIscore: those with a score of 40 or more were considered developmentally normal (n = 32), and those with a score below 40 were considered as having impaired development (n = 7). RESULTS: The severity of caries (DMFT) was negatively correlated with PDI (r = -0.82), and children with the lowest TEPSI score had the highest DFMT values. The average DMFT in children with normal development was 1.31, and 3.57 for those with impaired development. CONCLUSION: This pilot study indicates that the severity of dental caries is correlated with early childhood development.

Magnetic heating properties and neutron activation of tungsten-oxide coated biocompatible FePt core-shell nanoparticles.

Magnetic nanoparticles are highly desirable for biomedical research and treatment of cancer especially when combined with hyperthermia. The efficacy of nanoparticle-based therapies could be improved by generating radioactive nanoparticles with a convenient decay time and which simultaneously have the capability to be used for locally confined heating. The core-shell morphology of such novel nanoparticles presented in this work involves a polysilico-tungstate molecule of the polyoxometalate family as a precursor coating material, which transforms into an amorphous tungsten oxide coating upon annealing of the FePt core-shell nanoparticles. The content of tungsten atoms in the nanoparticle shell is neutron activated using cold neutrons at the Heinz Maier-Leibnitz (FRMII) neutron facility and thereby transformed into the radioisotope W-187. The sizeable natural abundance of 28% for the W-186 precursor isotope, a radiopharmaceutically advantageous gamma-beta ratio of γß≈30% and a range of approximately 1mm in biological tissue for the 1.3MeV ß-radiation are promising features of the nanoparticles' potential for cancer therapy. Moreover, a high temperature annealing treatment enhances the magnetic moment of nanoparticles in such a way that a magnetic heating effect of several degrees Celsius in liquid suspension - a prerequisite for hyperthermia treatment of cancer - was observed. A rise in temperature of approximately 3°C in aqueous suspension is shown for a moderate nanoparticle concentration of 0.5mg/ml after 15min in an 831kHz high-frequency alternating magnetic field of 250Gauss field strength (25mT). The biocompatibility based on a low cytotoxicity in the non-neutron-activated state in combination with the hydrophilic nature of the tungsten oxide shell makes the coated magnetic FePt nanoparticles ideal candidates for advanced radiopharmaceutical applications.

[Can vesicoureteral reflux be predicted in infants with urinary infection?]. / ?Se puede precedir el reflujo vesicoureteral en lactantes con infección urinaria?

AIMS: To look forward for a formulae able to predict the presence of vesicoureteral reflux (VUR) in the first urinary tract infection (UTI) in infants. SUBJECTS AND METHODS: We had studied all the diagnosticated first UTI in breast-fed babies in our hospital along 21/2 years. All had been subjects of a renal ultrasound scan, VCUG and CRP test. We have analyzed the result by diagnosis test and logistic regression. RESULTS: We have studied 267 infants aged between 2 days and 24 months old.17,33% manifested UTI caused by germs different than E Coli, 40 subjects presented anomalies in the ultrasound scan and 108 manifested VUR. Oostenbruck s score had been useless in detecting VUR subjects. In the multivariable analysis the two variables of anomalies in the ultrasonographic scan and non E Coli caused UIT were the only ones to presented statistical significance to sign the presence of VUR and of the likeness of VUR of grade > or = 3. The negative probability coefficients for infants with ultrasonographics anomalies and/or UTI non E Coli produced were of 0,78 (IC 0,67-0,90) for all degrees of VUR, 0,25 (IC 0,10-0,52) for VUR with degree > or = 3 and 0 (IC 0-0,67) for VUR with degree > or = 4. CONCLUSIONS: We deduced that in children younger of 24 months old that suffer their first UTI the indication to proceeded with a VCUG could be limited to the subjects with present anomalies in the renal ultrasound scan and/or UTI non E Coli, thought there will precised more studies to confirm this findings.

Variables associated with diagnostic delay in immigrant groups with tuberculosis in Madrid.

OBJECTIVE: To identify variables associated with total diagnostic delay (TDD), patient delay (PD) and health service delay (HSD), among the tuberculous immigrant population in the Autonomous Community of Madrid (ACT). METHODOLOGY: Tuberculosis cases diagnosed in 15 hospitals in the ACT in 2003 were interviewed face-to-face and medical records were reviewed. A descriptive study was conducted, followed by univariate and multivariate analysis using non-conditional logistic regressions. 50th (p50) and 75th (p75) percentiles of the different diagnostic delay components were analysed as dependent variables. RESULTS: For the 296 cases included, the mean TDD was 40.5 days (IQR 16.0-90.0), the PD was 15 days (IQR 6.5-30.0), and the HSD was 5 days (IQR 0.0-30.0). TDD-p75 is associated with seeking primary health care (OR 2.87, 95%CI 1.47-5.58). PD-p75 is associated with identification of fever (OR 0.49, 95%CI 0.25-0.92) and non-identification of cough (OR 1.87, 95%CI 1.05-3.36) as symptoms resulting in health care being sought. The HSD-p75 is associated with primary health care being sought (OR 3.81, 95%CI 1.87-7.78), health cover (OR 15.07, 95%CI 1.96-115.68) and negative smear results at the time of diagnosis (OR 1.98, 95%CI 1.01-3.91). CONCLUSIONS: The HSD needs to be reduced, mainly when health care is sought through the primary care services and among patients with negative smear results.

Sexually transmitted Chlamydia trachomatis, Neisseria gonorrhoeae, and HIV-1 infections in two at-risk populations in Barcelona: female street prostitutes and STI clinic attendees.

OBJECTIVE: To determine the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and HIV-1 infections in female street prostitutes and STI clinic attendees in Barcelona. DESIGN: This was a prospective study carried out in two four-month periods over two years. Urine specimens were tested for CT and NG using a PCR pooling algorithm. Among street prostitutes HIV-1 testing in urine was also carried out. RESULTS: The prevalences of CT, NG, and HIV-1 in female street prostitutes (n=301) were 4.7%, 3.7%, and 1.0%, respectively. Women from Eastern Europe had the highest prevalence of CT (p=0.01). Prevalences of CT, NG, and HIV-1 among all clinic attendees (n=536) were 4.3%, 4.5%, and 4.4%, respectively. Prevalence of HIV-1 infection among homosexual men was higher compared with heterosexual men and women (p<0.001). CONCLUSIONS: Overall CT prevalence is currently lower than in other European countries, although it could increase as a result of immigration. Rates of HIV-1 and of NG are higher among homosexual than among heterosexual men.

[Thrombolytic treatment in acute ischemic stroke in a center without previous experience. Development of internal organization and first results]. / Tratamiento trombolítico del ictus isquémico agudo en un centro sin experiencia previa. Desarrollo de la organización interna y primeros resultados.

BACKGROUND AND OBJECTIVE: Treatment of acute ischemic stroke within three hours with intravenous tissue-type plasminogen activator (t-PA) has been recently approved by the European Drug Agency. We present the development of an internal organization system that has permitted thrombolytic treatment in our center without previous experience as well as the results of the first year. PATIENTS AND METHOD: Development of the thrombolysis educational program for the staff informed, of the internal organization system, and combined care protocols among the participating services. Prospective registry of patients treated with t-PA within the period 1/2004-2/2006. We collected demographic data, stroke assessment scales score (NIHSS), time to treatment, seven day and three months mortality, symptomatic hemorrhagic transformation, systemic bleedings, functional independency at three months, early significant improvement and significant deterioration. RESULTS: Fifty-three patients were treated. Mean age: 65 +/- 13 years; 56% women. Mean NIHSS pre-treatment: 14 +/- 4.7. Mean time to hospital arrival: 62 +/- 40 minutes; door-to-treatment: 68 +/- 22 minutes, and mean time from stroke onset to treatment: 130 +/- 31 minutes. Symptomatic hemorrhagic transformation: 5.8%. Systemic bleeding: 3.8%. Seven day mortality: 5.6%; three months mortality: 15.1%. Early significant improvement: 51%. Significant neurological deterioration: 7.5%. Functional independency at three months: 51%. CONCLUSIONS: Treatment of acute ischemic stroke within three hours with intravenous t-PA is safe and is associated with a favourable outcome when it is applied by neurologists specifically trained in acute stroke management.

Evaluation of a commercial enzyme immunoassay for HIV screening in urine.

A cross-sectional study was conducted to evaluate the utility of a commercial enzyme immunoassay (EIA) as a screening test for detecting HIV-1 antibody in urine in a population at risk for HIV infection in Catalonia, Spain. Paired urine and serum samples were collected consecutively from 99 patients who attended two drug-dependency treatment centres and 151 patients who attended a sexually transmitted diseases (STD) clinic in Barcelona. Antibodies against HIV in urine samples were detected using the Calypte HIV-1 Urine EIA (Calypte Biomedical Corporation, Berkeley, CA, USA) and confirmed by urine-based Western blot (WB) analysis. Sera were analysed using Bioelisa HIV-1+2 EIA (Biokit Laboratories, Barcelona, Spain), and the results were verified using serum-based WB analysis. Results of both urine and serum testing were available for 246 of 250 participants. For 52 individuals the results of both urine and serum testing were positive and for five the results were discordant (2 with urine-negative/serum-positive results and 3 with urine-positive/serum-negative results). The respective sensitivity and specificity values obtained for the urine EIA were 100% and 96.2% for intravenous drug users (IDUs) and 80% and 99.3% for persons attending the STD clinic. According to the 1997 UNAIDS/WHO strategy I recommendations, these values are acceptable for surveillance purposes, particularly in populations with a high prevalence of HIV infection.

[HIV infection and other sexually-transmitted infections among immigrants in Barcelona]. / Infección por el virus de la inmunodeficiencia humana y otras infecciones de transmisión sexual en inmigrantes de Barcelona*

BACKGROUND: Immigration is a recent phenomenon in Spain. Certain subgroups of the immigrant population may be vulnerable to acquiring sexually transmitted infections (STI). MATERIAL AND METHODS: Descriptive study of the seroprevalenceof certain STI (HIV, hepatitis B and syphilis) and the general characteristicsn of persons tested for HIV infection in a specialized clinic in Barcelona during the year 2000. RESULTS: Seroprevalence of HIV was similar in immigrants and native residents(1.8% vs. 1.7% respectively). However, the seroprevalences of hepatitis B virus (anti-HBc) (19.5% vs. 8.3%) and syphilis (RPR 1 TPHA) (3.2% vs. 1.1%), as well as other STI and the practice of prostitution, were higher in immigrants. CONCLUSIONS: Several STI, including hepatitis B and syphilis, were found more frequently in immigrants than in the native population, whereas HIV seroprevalence was similar in the two groups.

Prick-prick with fresh foods in patients with latex allergy.

The quick spread of AIDS and other contagious infectious diseases has resulted in what was first voluntary, and subsequently recommended and compulsory, use of protection from contact with blood or bodily fluids. This protection has been especially widespread in the healthcare field. In the in vivo diagnosis of food allergy, it has been proven that the skin prick-prick test is sometimes more sensitive than skin prick test with commercial extracts. The aim of our study was to prove that handling fresh foods prepared for the prick-prick test with latex gloves can tamper with the results in patients with latex allergy. Statistically significant differences were found (p <0.001) between patients and controls in the prick-prick tests against the different foods after handling with latex gloves. No significant differences were found in controls for each prick-prick test for food with or without manipulation with latex gloves. Significant differences were found in the group of patients when performing prick-prick with the different foods before and after manipulation with latex gloves. We also observed that there were significant differences in prick-prick test between patients with latex sensitization and nonsensitized controls, and that the results of prick-prick test varied for each patient depending on whether or not foods had been handled with latex gloves.
