Um caso de Binswanger sob a lente de Merleau-Ponty

Pretendo, neste artigo, abordar um caso de Binswanger privilegiado por Merleau-Ponty. Nesse caso, o filósofo desenvolve a questão do estatuto do sintoma como uma forma de elaboração de vida, mas chega num impasse: como pensar essa elaboração sem que isso nos leve a negar que o sujeito se reestrutura totalmente diante de um impasse? Além do que, o que significa dizer que o sujeito elabora uma nova forma de vida? Veremos como a análise merleau-pontyana da psicanálise é peculiar, levando-o a negar um conceito chave da metapsicologia freudiana: o inconsciente.

Acid-base and biochemical stabilization and quality of recovery in male cats with urethral obstruction and anesthetized with propofol or a combination of ketamine and diazepam

This study compared acid-base and biochemical changes and quality of recovery in male cats with experimentally induced urethral obstruction and anesthetized with either propofol or a combination of ketamine and diazepam for urethral catheterization. Ten male cats with urethral obstruction were enrolled for urethral catheterization and anesthetized with either ketamine-diazepam (KD) or propofol (P). Lactated Ringer's solution was administered by intravenous (IV) beginning 15 min before and continuing for 48 h after relief of urethral obstruction. Quality of recovery and time to standing were evaluated. The urethral catheter was maintained to measure urinary output. Hematocrit (Hct), total plasma protein (TPP), albumin, total protein (TP), blood urea nitrogen (BUN), creatinine, pH, bicarbonate (HCO3-), chloride, base excess, anion gap, sodium, potassium, and partial pressure of carbon dioxide in mixed venous blood (pvCO(2)) were measured before urethral obstruction, at start of fluid therapy (0 h), and at subsequent intervals. The quality of recovery and time to standing were respectively 4 and 75 min in the KD group and 5 and 16 min in the P group. The blood urea nitrogen values were increased at 0, 2, and 8 h in both groups. Serum creatinine increased at 0 and 2 h in cats administered KD and at 0, 2, and 8 h in cats receiving P, although the values were above the reference range in both groups until 8 h. Acidosis occurred for up to 2 h in both groups. Acid-base and biochemical stabilization were similar in cats anesthetized with propofol or with ketamine-diazepam. Cats that received propofol recovered much faster, but the ketamine-diazepam combination was shown to be more advantageous when treating uncooperative cats as it can be administered by intramuscular (IM) injection.

Effect of aspherical and yellow tinted intraocular lens on blue-on-yellow perimetry

PURPOSE: To investigate the possible effect of aspherical or yellow tinted intraocular lens (IOL) on contrast sensitivity and blue-on-yellow perimetry. METHODS: This prospective randomized bilateral double-masked clinical study included 52 patients with visually significant bilateral cataracts divided in two groups; 25 patients (50 eyes) received aspherical intraocular lens in one eye and spherical intraocular lens in the fellow eye; and 27 patients (54 eyes) received ultraviolet and blue light filter (yellow tinted) IOL implantation in one eye and acrylic ultraviolet filter IOL in the fellow eye. The primary outcome measures were contrast sensitivity and blue-on-yellow perimetry values (mean deviation [MD] and pattern standard deviation [PSD]) investigated two years after surgery. The results were compared intra-individually. RESULTS: There was a statistically significant between-group (aspherical and spherical intraocular lens) difference in contrast sensitivity under photopic conditions at 12 cycles per degree and under mesopic conditions at all spatial frequencies. There were no between-group significant differences (yellow tinted and clear intraocular lens) under photopic or mesopic conditions. There was no statistically significant difference between all intraocular lens in MD or PSD. CONCLUSION: Contrast sensitivity was better under mesopic conditions with aspherical intraocular lens. Blue-on-yellow perimetry did not appear to be affected by aspherical or yellow tinted intraocular lens. Further studies with a larger sample should be carried out to confirm or not that hypotheses.

Atuação missionária jesuítica na América portuguesa: a peculiar via renascentista, sacramental e tridentina à salvação no(s) Novo(s) Mundo(s)

A Companhia de Jesus foi o emblema mais representativo da transformação e realização da nova prática da catequese na sua atuação missionária,durante a primeira Idade Moderna. A transformação vinha ocorrendo a partir da contraposição entre Reforma e Contrarreforma, no estabelecimento de analogias e diferenças da missão entre Europa, América e Ásia, e, finalmente, na esteira dos ecos das decisões conciliares de Trento em Lima. A partir dos tópicos que dividem o texto, o presente trabalho percorre - em uma síntese inevitavelmente esquemática, mas aberta à perspectiva de recentes investigações sobre o tema - essas problemáticas. Pensamos assim que elas possam ganhar clareza e coerência expositiva, mas, sobretudo, uma capacidade de inteligibilidade dos temas propostos, tendo em vista um resultado que não seja apenas uma aquisição (sempre parcial), mas, sobretudo, um novo ponto de partida para ulteriores investigações sobre as diretrizes apontadas.
