« Laudato si’, mi' Signore » — « Alabado seas, mi Señor », cantaba san Francisco de Asís. En ese hermoso cántico nos recordaba que nuestra casa común es también como una hermana, con la cual compartimos la existencia, y como una madre bella que nos acoge entre sus brazos: « Alabado seas, mi Señor, por la hermana nuestra madre tierra, la cual nos sustenta, y gobierna y produce diversos frutos con coloridas flores y hierba ». Esta hermana clama por el daño que le provocamos a causa del uso irresponsable y del abuso de los bienes que Dios ha puesto en ella. Hemos crecido pensando que éramos sus propietarios y dominadores, autorizados a expoliarla. La violencia que hay en el corazón humano, herido por el pecado, también se manifiesta en los síntomas de enfermedad que advertimos en el suelo, en el agua, en el aire y en los seres vivientes. Por eso, entre los pobres más a...

The expansion of the english textile industry after the second industrial revolution created a great demand of raw materials, which allowed Peru's southern andean region to connect itself with the international market trough alpaca wool exports. This article analyzes how two inmigrants, who arrived to Peru seeking to participate in the alpaca fiber trade, wereable to consolidate themselves in the trade field, and to create later two important economic groups which have built vertically integrated textile industries employing different growth strategies.

The credit market is a typical one where the problem of asymmetric information exists. This raise two problems: one drawn by the impossibility to control all the borrowers' actions that could affect their capacity (insolvency default) and willingness (strategic default) to repay the loans granted, which constitutes hidden actions for lenders (moral hazard). The other problem is related to the inability of the lender to know all the credit applicant's relevant aspects in his lending decision (adverse selection or hidden information). This article focus on three non-conventional arrangements to ensure loan repayment established by formal and informal lenders to resolve the informational problem, the first established by the Cajas Municipales, the second by the NGOs, and the third is an interesting experience of vertical integration between formal (bank) and informal (NGO) lenders. All thes...

This article looks at the determinants of the choice of productive projects involving intertemporal contracts in rural Peru. In a setting where the formal education is limited, the successful launching of new financial instruments may be affected by the lack of proper understanding of their main features,  as well as judgment biases. We find that education, a source of judgement bias, and (weakly) risk aversion, affect such a project choice. In contrast, wealth does not appear to play a role in explaining project choice.

Objective: To determine the epidemiological characteristics, location of the infarction, type and times of reperfusion, as well as in-hospital adverse events, distributed by sex in patients with ST-segment elevation myocardial infarction (STEMI) in Peru. Methods: It is a sub-analysis of the PEruvian Registry of ST-segment Elevation Myocardial Infarction (PERSTEMI), which was an observational, prospective and multicenter study about patients over 18years-old, who were hospitalized for ST-segment elevation myocardial infarction. Epidemiological and clinical characteristics, management and in-hospital adverse events were compared according to sex. Results: 396 patients were studied, 20.9% were female, with a predominance of octogenarian populationover men. High blood pressure was the most frequent risk factor in women (74.7 Vs. 50%, p =0.001); as well as atypical clinical manifestations suc...

We present the case of a 38-year-old male with a diagnosis of Stanford A aortic dissection and associated coarctation of the thoracic aorta. Acute dissection associated with coarctation of the aorta is a rare problem and difficult to manage surgically. Establishing a cardiopulmonary bypass (CPB) with adequate flows is the main objective of the procedure; optimal cannulation ensures the protection of cerebral and visceral organs. We successfully performed aortic valve re-implantation surgery (T. David Surgery), replacement of the ascending aorta and aortic arch, as well as debranching of the supra-aortic trunks. The cannulation technique was axillary and femoral to guarantee flows through the coarctation area.

El presente trabajo se realizó en Sao Paulo, Brasil con la finalidad de establecer la frecuencia de infección toxoplásmica en cerdos destinados al consumo humano. Mediante la prueba de ELISA, se analizaron 303 sueros de suinos beneficiados en un camal de la ciudad. Los resultados dieron 9.57% de sueros reactores al Toxoplasma gondii (cutoff de 0.270) con un intervalo de confianza de 95% entre 6.26% y 12.88%. Al analizarse la variable sexo, se encontró un 10.31 % de infectadas entre las hembras y 9.22% entre los machos (P> 0,05). Estos hallazgos confirman la importancia que tiene la carne de cerdo como fuente de infección de la toxoplasmosis para el hombre.
