FADIGA E DEPRESSÃO NO IDOSO

A fadiga é um sintoma inespecífico, encontrado com freqüência na população. Ela é definida como sensação de cansaço físico profundo, perda de energia ou mesmo sensação de exaustão, e é importante a sua diferenciação com depressão ou fraqueza. Os transtornos depressivos e ansiosos constituem os transtornos psiquiátricos mais freqüentes no idoso, e quase sempre dão lugar a conseqüências graves neste grupo etário. Este estudo visa avaliar a influência da ansiedade e depressão sobre o desencadeamento de fadiga e evolução de problemas de saúde e de comportamentos peculiares ao processo de envelhecimento. Trata-se de um estudo, do tipo caso-controle investigando ansiedade, depressão e fadiga. Foram avaliados 61 indivíduos com 60 anos de idade ou mais. Um grupo controle constituído por 60 indivíduos jovens (idade até 35 anos), foram selecionados entre estudantes do Centro Universitário de Santo André que responderam um Questionário de Características Gerais, um Inventário de Ansiedade traço-estado, um Inventário de Depressão de Beck e uma Escala de Severidade de Fadiga. O grupo de idosos apresentou um escore significativamente maior em relação ao grupo controle na escala de severidade de fadiga. O grupo de idosos apresentou escore médio de 36,87 ± 14,61 enquanto o grupo controle apresentou escore médio de 31,47 ± 12,74 (t = 2,167; df = 119; p = 0,032). No entanto, o grupo de idosos apresentou escores significativamente maiores na escala de Beck (10,54 ± 8,63) em relação aos controles (6,83 ± 7,95); t = 2,455; df = 119; p = 0,016). Analisando-se apenas o grupo de indivíduos idosos, observou-se uma correlação significativa entre os escore da escala de severidade de fadiga e a escala de depressão de Beck (correlação de Pearson = 0,332; p = 0,009). Ainda trabalhando apenas com o grupo de indivíduos idosos, observou-se um escore significativamente maior da escala de severidade de fadiga naqueles indivíduos que praticavam atividade física regular, sendo, escore médio de 31,55 ± 13,36; (t = 2,203; df = 58; p = 0,032). A partir da análise dos resultados deste estudo pôde-se concluir que o grupo de indivíduos idosos apresentam estatisticamente significante escore maior, quando comparado com o grupo controle, apresentando mais sintomas de fadiga e depressão. Estes sintomas de fadiga ocorreram em conjunto com sintomas depressivos sugerindo uma possível correlação entre estes. Quando se observou apenas os idosos, esta correlação foi confirmada. Analisado-se ainda somente o grupo de indivíduos idosos observa-se que o grupo de idosos que praticam atividade física regularmente apresentam menos sintomas fadiga que o grupo que não pratica atividade física.(AU)

Incorporation and release of macromolecules from biodegradable polymer vehicles

The initial objective of this work was to evaluate and introduce fabrication techniques based on W/0/W double emulsion and 0/W single emulsion systems with solvent evaporation for the incorporation of a surrogate macromolecule (BSA) into microspheres and microcapsules fabricated using P(HB-HV}, PEA and their blends. Biodegradation, expressed as changes in the gross and ultrastructural morphology of BSA loaded microparticulates with time was monitored using SEM concomitant with BSA release. Spherical microparticulates were successfully fabricated using both the W/0/W and 0/W emulsion systems. Both microspheres and microcapsules released BSA over a period of 24 to 26 days. BSA release from P(HB-HV)20% PCL 11 microcapsules increased steadily with time, while BSA release from all other microparticulates was characterised by an initial lag phase followed by exponential release lasting 6-11 days. Microcapsules were found to biodegrade more rapidly than microspheres fabricated from the same polymer. The incubation of microparticulates in newborn calf serum; synthetic gastric juice and pancreatin solution showed that microspheres and microcapsules were susceptible to enzymatic biodegradation. The in vitro incubation of microparticulates in Hank's buffer demonstrated limited biodegradation of microspheres and microcapsules by simple chemical hydrolysis. BSA release was thought to ocurr as a result of the macromolecule diffusing through either inherent micropores or via pores and channels generated in situ by previously dissolved BSA. However, in all cases, irrespective of percentage loading or fabrication polymer, low encapsulation efficiencies were obtained with W/0/W and 0/W techniques (4.2±0.9%- 15.5±0.5%,n=3), thus restricting the use of these techniques for the generation of microparticulate sustained drug delivery devices. In order to overcome this low encapsulation efficiency, a W/0 single emulsion technique was developed and evaluated in an attempt to minimise the loss of the macromolecule into the continuous aqueous phase and increase encapsulation efficiency. Poly(lactide-co-glycolide) [PLCG] 75:25 and 50:50, PEA alone and PEA blended with PLCG 50:50 to accelerate biodegradation, were used to microencapsulate the water soluble antibiotic vancomycin, a putative replacement for gentamicin in the control of bacterial infection in orthopaedic surgery especially during total hip replacement. Spherical microspheres (17.39±6.89~m,n=74-56.5±13.8~m,n=70) were successfully fabricated with vancomycin loadings of 10, 25 and 50%, regardless of the polymer blend used. All microspheres remained structurally intact over the period of vancomycin release and exhibited high percentage yields( 40. 75±2 .86%- 97.16±4.3%,n=3)and encapsulation efficiencies (47.75±9.0%- 96.74±13.2%,n=12). PLCG 75:25 microspheres with a vancomycin loading of 50% were judged to be the most useful since they had an encapsulation efficiency of 96.74+13.2%, n=12 and sustained therapeutically significant vancomycin release (15-25μg/ml) for up to 26 days. This work has provided the means for the fabrication of a spectrum of prototype biodegradable microparticulates, whose biodegradation has been characterised in physiological media and which have the potential for the sustained delivery of therapeutically useful macromolecules including water soluble antibiotics for orthopaedic applications.

Distributed temperature sensor based on Brillouin loss in an optical fibre for transient threshold monitoring

A distributed temperature sensor for transient threshold monitoring with a 22 km sensing length, based on the Brillouin loss in standard communications fibre, is demonstrated. The system can be used for real-time monitoring of a preset temperature threshold. Good S/N ratios were achieved with only 8–16 sample averages giving a response time of 2 to 4 s with a temperature uncertainty of ±1 °C.

Seroepidemiology of Herpes Simplex virus type 1 and 2 in Western and Southern Switzerland in adults aged 25-74 in 1992-93: a population-based study.

BACKGROUND: Genital herpes is one of the most prevalent sexually-transmitted diseases, and accounts for a substantial morbidity. Genital herpes puts newborns at risk for very severe disease and also increases the risk of horizontal HIV transmission. It thus stands as an important public health problem. The recent availability of type-specific gG-based assays detecting IgG against HSV-1 and HSV-2 allows to establish the prevalence of each subtype. Worldwide, few data have been published regarding the seroprevalence in general populations of HSV-2, the major causative agent for genital herpes, while no data exist regarding the Swiss population. METHODS: To evaluate the prevalence of IgG antibodies against HSV-1 and HSV-2 in Switzerland, we used a population-based serum repository from a health examination survey conducted in the Western and Southern area of Switzerland in 1992-93. A total of 3,120 sera were analysed by type-specific gG-based ELISA and seroprevalence was correlated with available volunteers characteristics by logistic regression. RESULTS: Overall, seroprevalence rates were 80.0 +/- 0.9% (SE, 95% CI: 78.1-81.8) for HSV-1 and 19.3 +/- 0.9% (SE, 95% CI: 17.6-21.1) for HSV-2 in adults 35-64 year old. HSV-1 and HSV-2 seroprevalence increased with age, with a peak HSV-2 seroprevalence in elderly gentlemen, possibly a seroarcheological evidence of sexually transmitted disease epidemics during World War II. Risk factors for HSV-2 infection included female sex, marital status other than married, and size of town of residence larger than 1500 inhabitants. Unexpectedly and conversely to HSV-1, HSV-2 seroprevalence increased with educational level. HSV-2 infection was less prevalent among HSV-1 infected individuals when compared to HSV-1 uninfected individuals. This effect was most apparent among women at high risk for HSV-2 infection. CONCLUSIONS: Our data demonstrate that by the early nineties, HSV-2 had spread quite largely in the Swiss population. However, the epidemiology of HSV-2 in Switzerland presents paradoxical characteristics, e.g. positive correlation with education level, that have not been observed elsewhere.
