Most patients undergoing limb amputations suffer significant emotional changes. The aim of this study was to estimate the prevalence of suicide attempts and depression in a sample of Mexican patients with limb amputations and, second, to determine whether the patients' functionality correlates with the presence of depression. We studied 40 patients who had undergone a limb amputation. The suicide attempt was evaluated using the Suicide Intent Scale. The depression was assessed using the Hamilton Depression Rating Scale, whereas the functionality of the patients was measured using the Functional Independence Measure. In this sample, 90% were men, whereas only 10% were women. In terms of the suicide behavior, we identified suicide attempts in 27.5% of the patients. The rate of depression was 92.5%. In the Functional Independence Measure, we observed that 57.5% of the patients showed complete dependence. Finally, a significant correlation was found between depression and functionality (r=-0.75, P<0.001). The findings of the present study highlight the high incidence of suicide attempts and depression in Mexican patients with limb amputations. Also, we identified a correlation between the lack of functional independence and depression. Therefore, holistic interventions are necessary in these patients: rehabilitation therapy to increase their functionality, and psychological and pharmacology therapy to decrease suicidal behavior and depression. Finally, more studies using larger samples are necessary to obtain conclusive results.

The irrigation methods offer a good alternative for increasing water use efficiency. The main purpose of this study was to identify the best irrigation level for Habanero pepper (Capsicum chinense Jacq.) plants based on available water capacity (AWC) of substrate. An experiment carried out with three irrigation levels (20, 40 and 60% of AWC) and five genotypes (H225, H241, H244, H226 and Jaguar). The irrigation level of 20% decreased the soil water potential to cause water stress in plants. At an irrigation level of 40%, average jaguar plant height (92 cm) and H241 (79 cm), genotypes were greater than under the other treatments. Average leaf area of H225, H241 and H244 plants was at least 48% greater than Jaguar plants. Average total dry matter of H241 and Jaguar plants, were 30 and 28% greater than H226 plants; and values of maximum photochemical quantum yield (Fv/Fm), relative electron transport rate and effective photochemical quantum yield of photosystem II were higher in H241, H244 and H226 plants; i.e. they are less probably due to photo inhibition damage. However, flowering time was earlier in plants with an irrigation level (IL) of 20% than plants with an IL of 40%, this was a consequence of stress due to water deficit. The 60% irrigation treatment caused flooding and all genotypes died before the inflorescence stage. These results suggest the enforcement of a suitable irrigation level based in available water capacity of substrate coupled with a vigorous genotype can encourage healthy plants and high water use efficiency.

RESUMENEl objetivo de esta revisión fue establecer una asociación entre el nivel de actividad física realizada y la reducción del riesgo de muerte en pacientes hipertensos. Para la identificación de los documentos de esta revisión se realizó una búsqueda que abarcó estudios epidemiológicos tipo cohorte; las publicaciones relevantes fueron identificadas en las bases de datos biomédicas PubMed y Cochrane Collaboration, la estrategia de búsqueda siguió las recomendaciones de PRISMA. Los resultados mostraron que existe una asociación entre el nivel de actividad física y el riesgo de muerte en pacientes hipertensos. Se encontró una disminución del riesgo de muerte que oscila entre el 17-67% en los hipertensos que realizan altos niveles de actividad física. Los resultados apoyan la teoría de que la actividad física regular se asocia con la reducción del riesgo de muerte en pacientes hipertensos y se sugiere que este efecto protector puede ser para muerte por enfermedad cardiovascular y para muerte por cualquier causa, además se observó que en los estudios que consideraron edades de 40 a 80 años, la reducción del riesgo relativo fue del 28-67%. Por lo que se sugiere que probablemente la actividad física genere mayores beneficios en los grupos etarios de mayor edad. Palabras clave: Actividad física; Hipertensión; Mortalidad ABSTRACTThe objective or aim of this review was to determine a relation between the level of realized physical activity and the reduction of the risk of death in hypertensive patients. A search was conducted for the identification of the documents from this review that included epidemiological cohort studies, relevant publications were identified in the biomedical databases PubMed and Cochrane Collaboration, the search strategy follows the recommendations of PRISMA. The results showed that an association exists between the level of physical activity and the risk of death in patients with hypertension.

The establishment and distribution of exotic biological control agents for the silverleaf whitefly in Puerto Rico was evaluated. Five hundred thirty parasitoids were recovered from 99 sample sites. Encarsia spp. represented over 90% of the total samples profiled, whereas Eretmocerus spp. represented only 9.5%. Eretmocerus hayati, from Pakistan, represented 56% of the total of that genus, followed by Er. mundus from Spain (38%). An Encarsia sophia species from Pakistan was the most abundant, representing 29.6% of the total number of specimens from that group and 26.8% of the total number of specimens recovered during the study. Five unidentified, and possibly undescribed, species from Puerto Rico were detected during the study. Two of the local species represent about 23% of the total number of specimens collected.
