Background. Cardiogenic shock (CS) remains a major challenge in contemporary cardiology. Data regarding CS etiologies and their prognosis are limited and mainly derived from tertiary referral centers. Aims. To investigate the current etiologies of cardiogenic shock and their associated short- and long-term outcomes in a secondary center without surgical back-up. Methods. We performed an observational prospective monocenter study. All patients admitted for a first episode of CS related to left ventricular dysfunction were enrolled. The definition of CS was consistent with the European Society of Cardiology guidelines. Patients were followed for 6 months. Etiologies were analyzed, and survival rates derived from Kaplan-Meier estimates were compared with the log-rank test. Results. Between January 2015 and January 2016, 152 patients were included. The first most common cause of CS was acute decompensation of chronic heart failure (CHF). Acute coronary syndromes (ACS) were the second most common cause of CS (35.4%). At one month, the all-cause mortality rate was 39.5% and was similar between ACS and CHF (43% vs 35%, respectively; p=0.7). In a landmark analysis between 1 and 6 months, we observed a significantly higher mortality in patients with CHF than in patients with ACS (18% vs. 0%; p=0.01). Conclusions. In the present registry, acute decompensation of chronic heart failure was the most common cause of CS, while ACS complicated by CS was the second most common cause. Of importance, acute decompensation of CHF was associated with a significantly worse outcome than ACS in the long term.

Advanced phylogenetic analyses of the orchid subtribe Aeridinae has been conducted using DNA sequences of ITS region of nrDNA andmatK of cpDNA. In the preliminary work, we only involved the most representative Asian genera of the subtribe. Further, to establish more robust relationships in the Aeridinae, in this study we have extended the sampling to include Australasian specimens. Our analyses revealed that: (1) the subtribe is reorganised by four major groups with 11 subgroups (This is inconsistent with previous classification systems of the subtribe); (2) the Australasian region is a secondary center of diversification of the subtribe; (3) vegetative features have shown to have greater value than reproductive one in determining major groups in the subtribe; and (4) at genus level, some genera, i.e. Phalaenopsis,Cleisostoma, Sarcochilus, and Aerides are shown to be non-monophyletic. This study also resolved the taxonomic status ofAerides flabellata Rolve ex Downie, a species with a debatable generic position.

The human ilium is significantly shorter and broader than those of all other primates. In addition, it exhibits an anterior inferior iliac spine (AIIS) that emerges via a secondary center of ossification, which is unique to hominids (i.e., all taxa related to the human clade following their phyletic separation from the African apes). Here, we track the ontogeny of human and other primate ossa coxae. The human pattern is unique, from anlage to adulthood, and fusion of its AIIS is the capstone event in a repositioning of the anterior gluteals that maximizes control of pelvic drop during upright walking. It is therefore a hominid synapomorphy that can be used to assess the presence and age of bipedal locomotion in extinct taxa.

AbstractArroyo de Piedra occupies a strategic position between the sites of Dos Pilas and Tamarindito, the dominant polities in the Petexbatun region. Temples, palaces, sculptured monuments, quarries, and a defensive wall reflect the importance of this small site. Archaeological and epigraphic investigations conducted by Vanderbilt University from 1990 to 1994 demonstrate that Arroyo de Piedra was founded and ruled by members of the royal family of Tamarindito during the Early Classic. In the Late Classic, Arroyo de Piedra was absorbed by the expansionistic Dos Pilas dynasty through a matrimonial alliance. The marriage was apparently imposed by means of coercion as suggested by evidence of intentional destruction of local sculpture. The center was abandoned during the Terminal Classic, after the fall of Dos Pilas.
