Determinants of pediatric cataract program outcomes and follow-up in a large series in Mexico.

PURPOSE:

To report determinants of outcomes and follow-up in a large Mexican pediatric cataract project.

SETTING:

Hospital Luis Sanchez Bulnes, Mexico City, Mexico.

METHODS:

Data were collected prospectively from a pediatric cataract surgery program at the Hospital Luis Sanchez Bulnes, implemented by Helen Keller International. Preoperative data included age, sex, baseline visual acuity, type of cataract, laterality, and presence of conditions such as amblyopia. Surgical data included vitrectomy, capsulotomy, complications, and use of intraocular lenses (IOLs). Postoperative data included final visual acuity, refraction, number of follow-up visits, and program support for follow-up.

RESULTS:

Of 574 eyes of 415 children (mean age 7.1 years +/- 4.7 [SD]), IOLs were placed in 416 (87%). At least 1 follow-up was attended by 408 patients (98.3%) (mean total follow-up 3.5 +/- 1.8 months); 40% of eyes achieved a final visual acuity of 6/18 or better. Children living farther from the hospital had fewer postoperative visits (P = .04), while children receiving program support had more visits (P = .001). Factors predictive of better acuity included receiving an IOL during surgery (P = .04) and provision of postoperative spectacles (P = .001). Predictive of worse acuity were amblyopia (P = .003), postoperative complications (P = .0001), unilateral surgery (P = .0075), and female sex (P = .045).

CONCLUSIONS:

The results underscore the importance of surgical training in reducing complications, early intervention before amblyopia (observed in 40% of patients) can develop, and vigorous treatment if amblyopia is present. The positive impact of program support on follow-up is encouraging, although direct financial support may pose a problem for sustainability. More work is needed to understand reasons for worse outcomes in girls.

Inflation targeting and the consistency of monetary policy decisions in Mexico: an empirical analysis with discrete choice models

This paper examines the nature of monetary policy decisions in Mexico using discrete choice models applied to the Central Bank's explicit monetary policy instrument. We find that monetary policy adjustments in Mexico have been strongly consistent with the CB's inflation targeting strategy. We also find evidence that monetary policy responds in a forward-looking manner to deviations of inflation from the target and that observed policy adjustments exhibit asymmetric features, with stronger responses to positive than to negative deviations of inflation from the target and a greater likelihood of policy persistence during periods when monetary policy is tightened, compared with periods when policy is loosened.

Luta Armada em Portugal (1970-1974)

A problemática do recurso à luta armada para derrubar a ditadura em Portugal gerou discussões, debates e rupturas no seio da oposição portuguesa muito antes de terem surgido as primeiras organizações que realizaram acções armadas. Foi no rescaldo da campanha para as eleições presidenciais de 1958, perante o apoio popular à campanha de Humberto Delgado, candidato da oposição, e a constatação da dimensão da fraude eleitoral, que ocorreram as primeiras discussões acerca da inevitabilidade recorrer à violência armada para derrubar a ditadura. Porém, apenas na década de 70 as circunstâncias políticas, económicas e sociais no país favorecem o aparecimento de outras organizações armadas. Os quase dez anos de guerra colonial tinham desgastado o regime e as manifestações contra a guerra eram cada vez maiores, com o numero de desertores e refractários a crescer de ano para ano. Ao mesmo tempo, o pais ia-se industrializando e terciarizando; assistia-se ao crescimento da classe média, da escolarização, da emigração e a uma mudança de mentalidade, trazida pelo acesso cada vez maior ao que se passava no mundo. Seria neste contexto que as formas tradicionais de oposição, baseadas em manifestações pacíficas e abaixo-assinados, são sentidas como ultrapassadas e ineficazes e começam a proliferar as organizações marxistas-leninistas que teorizavam sobre a luta armada e concebiam planos de acções armadas contra o regime, aumentando o número daqueles que defendiam que o regime só cairia com o recurso à violência. Em 1967, a LUAR, levava a cabo a primeira acção armada contra o regime, o assalto à agência do Banco de Portugal na Figueira da Foz, para obter dinheiro que seria utilizado no financiamento de futuras acções armadas. Em 1970, o Partido Comunista Português, depois de um prolongadíssimo período de maturação, avançava com a ARA que levou a cabo a primeira acção em Outubro desse ano, a sabotagem ao navio Cunene que participa da logística de apoio à guerra colonial. Em 1971, foram as Brigadas Revolucionárias que desencadearam a primeira acção, um atentado bombista contra o Quartel da Nato na Fonte da Telha. Até ao 25 de Abril de 1974, várias acções armadas seriam cometidas por estas organizações, com a particularidade de apenas atingirem o aparelho repressivo e militar do regime, e de seguirem o princípio irredutível de não fazer vítimas mortais entre os civis. O 25 de Abril de 1974, corresponderia ao epílogo de um processo de contestação armada ao Estado Novo que foi acelerando nos seus derradeiros anos.

Diagenesis and geochemical stratigraphy of Upper Pennsylvanian madera brachiopods, New Mexico

Owing to the fact that low-Mg calcite fossil shells are so important in paleoceanographic research, 249 brachiopod, cement and matrix specimens from two neighboring localities (Jemez Springs and Battleship Rock), of the Upper Pennsylvanian Madera Formation were analyzed. Of which, about 86% of the Madera brachiopods are preserved in their pristine mineralogy, microstructure and geochemistry. Cement and matrix samples, in contrast, have been subjected to complete but variable post-deposition~1 alteration. It is confirmed that the stable isotope data of brachiopods are much better than that of matrix material in defining depositional parameters. Because there is no uniform or constant relationship between the two data bases (e.g., from 0.1 to 3.0%0 for 0180 and from 0.2 to 6.7%0 for 013C in this study), it is not possible to make corrections for the matrix data. Regarding the two stratigraphic sections, elemental and petrographic analyses suggest that Jemez Springs is closer to Penasco Uplift than Battleship Rock. Seawater at Jemez Springs is more aerobic, and the water chemistry is more influenced by continental sources than that at Battleship Rock. In addition, there is a relatively stronger dolomitization in the mid-section of the Battleship Rock. Results further suggest that no significant biogenic fractionation or vital effects occurred during their shell secretion, suggesting that the Madera brachiopods incorporated oxygen and carbon isotopes in equilibrium with the ambient seawater. This conclusion is not only drawn from the temporal and spatial analyses, but also supported by brachiopod inter-generic comparison (Composita and Neospirifer) and statistical analysis ( t-test).
