Background:
The early clinical predictors of respiratory failure in Latin Americans with Guillain–Barré syndrome (GBS) have scarcely been studied. This is of particular importance since Latin America has a high frequency of axonal GBS variants that may imply a worse prognosis.
Methods:We studied 86 Mexican patients with GBS admitted to the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, a referral center of Mexico City, to describe predictors of invasive mechanical ventilation (IMV).
Results:The median age was 40 years (interquartile range: 26–53.5), with 60.5% men (male-to-female ratio: 1.53). Most patients (65%) had an infectious antecedent (40.6% gastrointestinal). At admission, 38% of patients had a Medical Research Council (MRC) sum score <30. Axonal subtypes predominated (60.5%), with acute motor axonal neuropathy being the most prevalent (34.9%), followed by acute inflammatory demyelinating polyneuropathy (32.6%), acute motor sensory axonal neuropathy (AMSAN) (25.6%), and Fisher syndrome (7%). Notably, 15.1% had onset in upper limbs, 75.6% dysautonomia, and 73.3% pain. In all, 86% received either IVIg (9.3%) or plasma exchange (74.4%). IMV was required in 39.5% patients (72.7% in AMSAN). A multivariate model without including published prognostic scores yielded the time since onset to admission <15 days, axonal variants, MRC sum score <30, and bulbar weakness as independent predictors of IMV. The model including grading scales yielded lower limbs onset, Erasmus GBS respiratory insufficiency score (EGRIS) >4, and dysautonomia as predictors.
Conclusion:These results suggest that EGRIS is a good prognosticator of IMV in GBS patients with a predominance of axonal electrophysiological subtypes, but other early clinical data should also be considered.

The preservation of Military Macaw Ara militaris in Mexico required the implementation of a nationwide assessment evaluating its vulnerability using IUCN criteria. With the combined effort of several institutions, the abundance, location, dispersion, habitat availability, and climatic conditions of areas occupied by the species were determined. Although the species’ extent of occurrence is extensive (263,919 km2) only 29% of this constitutes area of occupancy. Published estimates indicate a series of isolated populations containing from four macaws to 215. Macaws occurred in 35 populations in four regions of 16 states containing an estimated 1,563–3,263 macaws; lower than required for long-term viability. Within regions, neighbouring populations were separated by an average of 68 km. The extent of occurrence is heterogeneous, and macaws inhabit areas that differ in elevation, precipitation, temperature, and forest cover. Higher local abundances occur in landscapes where annual precipitation is ≥1,100 mm, and primary forest availability ≥1,800 km2. Although the existence of undetected macaw groups in Mexico is possible, these are likely to contain only small numbers of individuals, as most detected areas with macaws contain less than 40 individuals, and larger concentrations are more likely to be noticed due to their conspicuous behaviour. The species is threatened primarily by its low overall abundance, fragmented distribution, and forest loss around populations with the highest abundance. With the information generated, it is possible to design and implement specific management and conservation strategies at different geographic scales for the recovery and maintenance of the species in Mexico. It is necessary to strengthen collaborative programmes among conservation organizations, government agencies, and local communities in each region of the country to organize and finance community-based actions such as monitoring, habitat restoration, protection from poaching and the creation of a network of conservation corridors and macaw reserves focused on conservation.

Infection by larval Echinococcus granulosus is usually characterized by tight inflammatory control. However, various degrees of chronic granulomatous inflammation are also observed, reaching a high point in infection of cattle by the most prevalent parasite strain worldwide, which is not well adapted to this host species. In this context, epithelioid and multinucleated giant macrophages surround the parasite, and the secreted products of these cells often associate with the larval wall. The phagocyte-specific S100 proteins, S100A8, S100A9 and S100A12, are important non-conventionally secreted amplifiers of inflammatory responses. We have analysed by proteomics and immunohistochemistry the presence of these proteins at the E. granulosus larva-host interface. We found that, in the context of inflammatory control as observed in human infections, the S100 proteins are not abundant, but S100A9 and S100A8 can be expressed by eosinophils distal to the parasite. In the granulomatous inflammation context as observed in cattle infections, we found that S100A12 is one of the most abundant host-derived, parasite-associated proteins, while S100A9 and S100A8 are not present at similarly high levels. As expected, S100A12 derives mostly from the epithelioid and multinucleated giant cells. S100A12, as well as cathepsin K and matrix metalloproteinase-9, also expressed by E. granulosus-elicited epithelioid cells, are connected to the Th17 arm of immunity, which may therefore be involved in this granulomatous response.

The rocky shore of central Chile is heavily harvested by mariscadores de orilla and skin-divers, but their catches are not considered in the fishery statistics. The aim of the present paper is to estimate the intensity of human predation and annual catch of each of the species taken at Las Cruces, Central Chile. The activity pattern of both categories of collectors demonstrate a temporal grouping. The observation of mariscadores de orilla and skin-divers in 3 sectors of fringe totalling 1,500 m of rocky shore during 12 months allowed us to estimate the annual catch per species caught (kg per year).

In 38 children with aortic coarctation between the age of three weeks and 16 years, 44 balloon dilation procedures were attempted. At initial catheterization (n=38), the mean gradient dropped from 49.6±21.2 mm Hg prior to dilation, to 15.3±15.8 mm Hg after the procedure (p>0.05). Twenty-six patients were recatheterized 3–24 months after the initial procedure. The mean gradient remained low at 12.7±15.2 mm Hg (range 0–64). Six of the 26 (23%) patients required a second dilation because of significant recoarctation. This proved successful in four, but in two patients, the second dilation failed, and they were referred for elective surgery. Thus, good overall results were obtained in 24 of the 26 (92.3%) patients undergoing reinvestigation following balloon dilation. Complications included requirements for blood transfusion in 9/44 (20%), chest pain during balloon inflation in 3/44 (6.8%), rupture of the balloon in 3/44 (6.8%), and femoral arterial thrombectomy in 3/44 (6.8%). At a mean clinical follow-up of 21 months, 21% of the patients had a weaker femoral pulse on the side used for balloon dilation, while 21% had mild hypertension measured in the arms despite the absence of a significant gradient. One patient (2.6%) developed an aortic aneurysm as a complication of the procedure. We conclude that balloon dilation is a safe and effective procedure in the majority of the patients with native aortic coarctation.

Non-surgical occlusion of the arterial duct (ductus arteriosus) has been shown to be effective. Its limitations are yet to be fully defined. We have attempted to elucidate this issue in the setting of our early experience with the procedure, utilizing the Rashkind double disc occluder. After clinical and echocardiographic evaluation, 56 consecutive patients were studied invasively. In two patients, the patent duct was considered too large for occlusion and in one patient it could not be crossed with the diagnostic catheter. In the remaining 53 patients (95%), an attempt to implant the double disc occluder was made. The mean age of all patients was 7.9 years (range 0.16 year to 29 years). There were 35 females (63%) and 21 males. The mean weight was 24.2 kg (range 6.7 kg–85 kg). In five patients (9.5%), the procedure failed. This was due to pull through of the 17 mm device in three patients. In another patient, because of a very small duct (post surgical ligation), it was not possible to deliver the distal legs of the 12mm device. In the last patient, the device embolized to the left pulmonary artery and was retrieved to the groin. Subsequent replacement was not attempted. In 48/53 patients (90.5%) the device was successfully implanted. Nine cases of the 48 in whom the device was implanted (18.8%) showed complete occlusion at 10 minutes and 22 more (45.8%) five to 24 hours after the procedure. A total of3 1/48 patients (64.5%) were discharged home the day following the procedure with no residual shunt, as judged by color flow Doppler studies. The mean duration of the procedure in all patients was 94 minutes (range 47 to 244). The fluoroscopy time ranged from 3 to 81 minutes with a mean of 17 minutes. Follow-up data (between five days and 18 months) are available in 20/48 patients. Three patients had a clinically detectable residual shunt, with an audible continuous murmur six months after the procedure. All three have undergone complete occlusion using a second device. One more patient showed spontaneous occlusion on follow-up. So far, a total of 35/48 patients (72.9%) have had complete occlusion of the patent duct. We conclude that not all patients with an arterial duct are amenable to occlusion using the Rashkind device. The procedure appears to be safe when performed by a suitably trained novice, nonetheless, and successful implantation can be achieved in over 90% of patients.

Background and purpose. Depressive symptoms are frequently associated with heart failure (HF), but the brain mechanisms underlying such association are unclear. We hypothesized that the presence of major depressive disorder (MDD) emerging after the onset of HF would be associated with regional cerebral blood flow (rCBF) abnormalities in medial temporal regions previously implicated in primary MDD, namely the hippocampus and parahippocampal gyrus.
Method. Using 99mTc-SPECT, we measured rCBF in 17 elderly MDD-HF patients, 17 non-depressed HF patients, and 18 healthy controls, matched for demographic variables. Group differences were investigated with Statistical Parametric Mapping.
Results. Significant rCBF reductions in MDD-HF patients relative to both non-depressed HF patients and healthy controls were detected in the left anterior parahippocampal gyrus and hippocampus (ANOVA, p=0·008 corrected for multiple comparisons) and the right posterior hippocampus and parahippocampal gyrus (p=0·005 corrected). In the overall HF group, there was a negative correlation between the severity of depressive symptoms and rCBF in the right posterior hippocampal/parahippocampal region (p=0·045 corrected).
Conclusions. These findings are consistent with the notion that the medial temporal region is vulnerable to brain perfusion deficits associated with HF, and provide evidence that such functional deficits may be specifically implicated in the pathophysiology of MDD associated with HF.

We show that the geodesic flow of a metric all of whose geodesics are closed is completely integrable, with tame integrals of motion. Applications to classical examples are given; in particular, it is shown that the geodesic flow of any quotient $M/\Gamma$ of a compact, rank one symmetric space $M$ by a finite group acting freely by isometries is completely integrable by tame integrals.

En el curso de estos últimos años, los países hispanoamericanos han venido celebrando con singular júbilo el sesquicentenario de sus independencias nacionales. El pensamiento de sus más altos valores humanos ha enriquecido la historiografía de nuestra América, y ha venido a confirmar en sentido crociano, que toda nuestra Historia es también hazaña de libertad. Nuestra lucha se agita contemporáneamente, pues cada día conquistamos y reconquistamos nuestra libertad. El hombre de nuestras naciones todavía se debate en servidumbres y esclavitudes, mas su libertad y dignidad son valores permanentes.
