RESUMEN
BACKGROUND@#Muscular imbalance in the core and hip is one of the major risk factors associated with PFPS. There is evidence that decreased strength of the hip musculature is present in individuals with PFPS. This decrease in hip strength can also affect the stability of the core and further predisposes an athlete to injury.@*OBJECTIVES@#This is a cross-sectional study that compares the hip muscle strength and core stability of collegiate football players with and without PFPS.@*METHODS@#25 participants (10 with PFPS and 15 without PFPS) participated in the study. Hip strength was measured using a digital handheld dynamometer. Core stability was assessed through the McGill Core Strength test and the 8-stage stability test.@*RESULTS@#The hip adductors showed to be significantly weaker in those with PFPS as compared to those without PFPS ( p=0.040). No differences were found in the hip flexor (p=0.812), hip extensor (p=0.460) and abductors (p=0.126) strength while the core musculature showed that there is a statistically significant difference on the endurance of the lateral core musculature (p<0.001) and trunk flexors (p=0.027) between the two groups.@*CONCLUSION@#Football athletes without PFPS in this study demonstrated greater core stability and hip adductor muscle strength compared to those without PFPS.

Background:The brown widow spider (Latrodectus geometricus Koch, 1841) has colonised many parts of the world from its continent of origin, Africa. By at least 1841, the species had successfully established populations in South America and has more recently expanded its range to the southern states of North America. This highly adaptable spider has been far more successful in finding its niche around the world than its famous cousins, the black widow, Latrodectus mactans, found in the south-eastern states of North America, and the red-back, Latrodectus hasselti, found mostly in Australia, New Zealand and Japan.Methods:We performed an extensive web search of brown widow sightings and mapped the location of each sighting using ArcGIS. Specimens reputedly of the species L. geometricus were collected at three localities in Peninsular Malaysia. The spiders were identified and documented based on an examination of morphological characteristics and DNA barcoding.Results:The spiders found in Peninsular Malaysia were confirmed to be Latrodectus geometricus based on their morphological characteristics and DNA barcodes. We recorded 354 sightings of the brown widow in 58 countries, including Peninsular Malaysia.Conclusion:Reports from the Americas and the Far East suggest a global-wide invasion of the brown widow spider. Herein we report the arrival of the brown widow spider in Peninsular Malaysia and provide notes on the identification of the species and its recently expanded range.(AU)

Se describen los hechos más destácados en cuatro casos de DBP grave, en recién nacidos de 24 a 28 semanas de gestación y de 700 a 1.170 gr. al nacer. Todos fueron tratados con IPPV por períodos entre 41 y 216 días. Entre los trastornos asociados destaca la persistencia del Ductus Citomegalovirus en uno. Dos casos se complicaron con obstrucción laríngea severa . La oxigenoterapia fue necesaria entre 98-315 días, dos pacientes fueron tratados en el domicilio después del alta, por plazos de 27 y 117 días. El total de días de hospitalizados varió entre 100 y 275 días. El seguimiento, hasta edades corregidas entre 8 y 24 meses, muestra desarrollo psicomotor normal en todos los casos y retardo pondo-estatural severo en uno. El pronóstico de la DBP, comparable al de otros recién nacidos de muy bajo peso, justifica el esfuerzo y el costo del tratamiento

Se efectuó una auditoría de las muertes ocurridas en la Unidad de Neonatolog'iade la Maternidad del Hospital del Salvador, entre el 1o de Julio de 1981 y el 30de Junio de 1983. En este período nacieron 22.200 niños y fallecieron 262. Se analizan las tasas de mortalidad, siendo el promedio de 11,80%. Se estudian los fallecidos de acuerdo a peso de nacimiento. En el grupo de niños de menos de 1.500g. de peso al nacer, hubo 135 fallecidos. Destacan como causa inmediata de muerte: la hemorragia intracraneana, la inmadurez extrema, el SDRI, sepsis y otras infecciones y las anomalías congénitas. En el grupo de 1.501 a 2.500 g. fallecieron 76 niños. Las causas inmediatas de muerte más frecuentes fueron: sepsis y otras infecciones, anomalías congénitas y hemorragia intracraneana. En el grupo de más de 2.500 g. fallecieron 51 niños y en ellos destaca como causa inmediata de muerte las anomalías congénitas
