La biblioteca virtual especializada de los derivados de la caña de azúcar: consideraciones, experiencias y perspectivas
Relationship of the type of feeding with some infant’s growth, nutritional state and mobility variables
Antecedentes: Las recomendaciones actuales para alimentación del niño durante el primer año de vida es iniciar la lactancia
materna tan pronto como sea posible y evitar el uso de cualquier tipo de alimentos o líquidos distintos a la leche de pecho durante
los primeros cuatro a seis meses de vida.
Objetivo: Determinar si el patrón de alimentación en las etapas iniciales de la vida postnatal influyen en las características del
crecimiento y el desarrollo del lactante durante el primer año de la vida.
Pacientes y métodos: Se estudiaron 77 lactantes pertenecientes a 14 consultorios del médico de la familia del Policlínico Docente
Bejucal en la provincia de La Habana. De ellos 27 lactaron de forma exclusiva por 4 meses y 50 iniciaron la alimentación
complementaria antes del cuarto mes. A todos los lactantes se les realizó un estudio clínico y antropométrico, al mes, tres, cinco,
nueve y doce meses del nacimiento. El análisis estadístico incluyó las variaciones de los estadígrafos descriptivos (media,
desviación estándar, e intervalos de confianza a 95%) así como un análisis de observaciones repetidas para conocer si las
variaciones de la evolución dependen del tiempo de lactancia materna exclusiva.
Resultados: Se pudo apreciar que no existen variaciones en la evolución de los valores de la media del peso hasta el noveno
mes del desarrollo. Las variaciones de la talla no muestran diferencias en su patrón de ganancia entre los grupos en todas las etapas
del desarrollo estudiadas. Hay diferencias en las cifras de morbilidad sobre todo en lo referente a las enfermedades respiratorias
y diarreicas.
Conclusiones: No se evidencian diferencias importantes relacionadas con la evolución del peso y la talla durante el primer año
de vida. La morbilidad se ve influida por el tipo de alimentación que se reciba durante el primer año de vida. Background: The present dietary recommendation in infant feeding is to begin breast feeding as soon as possible and avoid
the use of other kind of foods including liquids different of breast feeding during the first four to six months of life.
Sample and methods: From 14 ambulatory clinics, in Havana Province (Bejucal Community Policlinic), 77 infants were studied;
of them 27 received exclusive breast feeding during the first four months and 50 began their complementary feeding before the fourth
month. All children were examined and measured at 1, 3, 5, 9 and 12 months. Statistic analysis included the variation of the statistical
stadigraphs (media, standard deviation, and confident intervals at 95%). Repeated measures analyses were done to evaluate the
association of variables with type of feeding.
Results: There were no differences in mean values of weight and height until the ninth month. Weight increased in group
receiving early supplementation. There are differences in the morbidity figures mainly for respiratory and diarrhoeal diseases.
Conclusions: There are no significant differences related to evolution of weight and height during the first year of life. Morbidity
is under influences of the type of feeding used during the first year of life
Calidad de vida profesional de enfermería en urgencias de un hospital de referencia
Objective: The objective of this study was to measure the quality of professional life of nurses in their workplace in the emergency unit of a Hospital, through three dimensions intrinsic motivation, support and management workloads. Most studies on quality of life worldwide are made primarily in teaching groups and health professionals. According to various studies, this group is very likely to suffer burnout. If we improve the quality of care provided, we must start knowing how nursing professionals perceive quality of life, as well as whether there are constraining factors involved.Methods: Cross-sectional study survey of nurses working in an Emergency Unit of a Spanish public hospital. It was conducted between March and May of 2014. The sample consisted on 60 subjects. Data were collected using the CVP-35 questionnaire.Results: The response rate was high. The nurses perceived low quality of professional life. The professional quality of life correlates with management support and intrinsic motivation, although no association with the workload was found. Age is the demographic variable that influences how they perceive their quality of working life emergency nurses.Conclusion: Compared to other studies, if we improve the management support, perception of the quality of working life of nurses working in emergency increase.Objetivo: El objetivo de este estudio fue medir la Calidad de Vida Profesional de los enfermeros en la unidad de urgencias de un hospital en su puesto de trabajo, a través de tres dimensiones: motivación intrínseca, apoyo directivo y cargas de trabajo. La mayoría de estudios sobre calidad de vida a nivel mundial se hacen principalmente en colectivos de enseñanza y también los profesionales de la salud, sufren desgaste profesional, según estudios diversos. Si queremos mejorar la calidad de los cuidados prestados, debemos empezar conociendo cómo percibe el profesional de Enfermería dicha calidad de vida, así como si existen o no factores que la condicionen.Métodos: Estudio descriptivo transversal con análisis correlacional. El presente estudió investigó la calidad de vida profesional de los enfermeros de una Unidad de Urgencias de un Hospital público español. Fue llevado a cabo entre Marzo y Mayo de 2014. Para ello se utilizó el “cuestionario CVP-35”.Resultados: La tasa de respuesta fue alta. Los enfermeros percibieron una baja calidad de vida profesional. La calidad de vida profesional se correlaciona con el Apoyo directivo y la Motivación intrínseca, aunque no se asocia con la Carga de Trabajo. La edad es la variable sociodemográfica que influye en cómo perciben su calidad de vida profesional los enfermeros de urgencias.Conclusión: En relación con otros estudios, si mejoramos el Apoyo directivo, la percepción de la calidad de vida profesional de los profesionales de enfermería que trabajan en urgencias aumentaría.

Establecimiento de la glycine (Neonotonia wightii) con fertilizante mineral, estiércol vacuno y cal en suelos Ferralíticos y Fersialíticos
Because of its high raw protein content, and adaptation to different agroecosystems, Glycine is one of the most extended legumes over the country; nevertheless, it needs fertile and not too acid soils. In Camagüey province, most of cattle raising areas are located on soils whose fertility and pH are medium to low; for that reason, two experiments were carried out in glass-house conditions to determine the effect of three soil fertility improvers on Glycine (Neonotonia wightii) cv. Tinaroo, behavior in fersialitic and ferralitic soils. Pots of 1,5 kg of capacity were used to study three doses of mineral fertilizer, cattle manure and lime in a randomized design with a factorial arrangement and four repetitions, evaluated by a double classification variance test (P≤ 0,05) and when there were significant differences Dunca'ns multiple range test was applied for comparison in case of significant differences (P≤ 0,05). Significant increases in Glycine yields were detected when applying the three mentioned improvers, while the highest dry matter production (8,23 and 21,54 g/pot) was registered with 50 t/ha of cattle manure combined to intermediate P-K doses (50-100 and 100-200 kg/ha for ferralitic and fersialitic soils) in addition to 2 t/ha CaCo3. Moreover, Glycine showed suitable contents of raw protein (15,69 and 18,80 %) and calcium (0,86 and 1,44 %) for animal normal growing up.Por sus altos contenidos en proteína bruta y su adaptabilidad a diferentes agroecosistemas, la Glycine es una de las leguminosas que más se ha extendido por todo el país; pero requiere de suelos fértiles y no muy ácidos. En Camagüey la mayoría de las áreas ganaderas están ubicadas en suelos de fertilidad y pH de medios a bajos, por lo que en condiciones de casa de cristal se condujeron dos experimentos para determinar el efecto de tres mejoradores de la fertilidad del suelo sobre el establecimiento de la Glycine (Neonotonia wightii) cv. Tinaroo, en suelos Ferralíticos y Fersialíticos. En macetas de 1,5 kg de capacidad se estudiaron tres dosis de fertilizante mineral, estiércol vacuno y cal (CaCO3) en cada suelo, mediante un diseño completamente aleatorizado con arreglo factorial y cuatro repeticiones, que se evaluaron por análisis de varianza de doble clasificación (P≤ 0,05) y en los casos de significación las medias se compararon por la prueba de rango múltiple de Duncan (P≤ 0,05). Se encontró que los rendimiento aumentaron significativamente con la aplicación de los tres mejoradores y que las mayores producciones de materia seca (8,23 y 21,54 g/maceta) se obtuvieron con el empleo de dosis equivalentes a 50 t/ha de estiércol vacuno combinado con la dosis intermedia de P-K (50-100 y 100-200 kg/ha para el suelo Ferralítico y Fersialítico, respectivamente) así como cuando se añadieron 2 t/ha de CaCO3. Además se encontró que esta especie muestra contenidos adecuados de proteína bruta (15,69 y 18,80 %) y calcio (0,86 y 1,44 %) para el normal desarrollo de los animales
Common genetic variation in KATNAL1 non-coding regions is involved in the susceptibility to severe phenotypes of male infertility
Free PMC article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9546047/Background: Previous studies in animal models evidenced that genetic mutations
of KATNAL1, resulting in dysfunction of its encoded protein, lead to male infertility
through disruption of microtubule remodelling and premature germ cell exfoliation.
Subsequent studies in humans also suggested a possible role of KATNAL1 single nucleotide polymorphisms in the development of male infertility as a consequence of
severe spermatogenic failure.
Objectives: The main objective of the present study is to evaluate the effect of the
common genetic variation of KATNAL1 in a large and phenotypically well-characterised
cohort of infertile men because of severe spermatogenic failure.
Materials and methods: A total of 715 infertile men because of severe spermato genic failure, including 210 severe oligospermia and 505 non-obstructive azoospermia
patients, as well as 1058 unaffected controls were genotyped for three KATNAL1
single-nucleotide polymorphism taggers (rs2077011, rs7338931 and rs2149971).
Case–control association analyses by logistic regression assuming different models
and in silico functional characterisation of risk variants were conducted.
Results: Genetic associations were observed between the three analysed taggers and
different severe spermatogenic failure groups. However, in all cases, the haplotype
model (rs2077011*C | rs7338931*T | rs2149971*A) better explained the observed
associations than the three risk alleles independently. This haplotype was associated
with non-obstructive azoospermia (adjusted p = 4.96E-02, odds ratio = 2.97), Sertoli cell only syndrome (adjusted p = 2.83E-02, odds ratio = 5.16) and testicular sperm
extraction unsuccessful outcomes (adjusted p = 8.99E-04, odds ratio = 6.13). The in
silico analyses indicated that the effect on severe spermatogenic failure predisposition
could be because of an alteration of the KATNAL1 splicing pattern.
Conclusions: Specific allelic combinations of KATNAL1 genetic polymorphisms may
confer a risk of developing severe male infertility phenotypes by favouring the
overrepresentation of a short non-functional transcript isoform in the testis.This work was supported by the Spanish Ministry of Economy and

Evaluación de las causas de anestro en rebaños bovinos lecheros en Camagüey
To determine the reproductive, metabolic, health and food status and evaluate the physical-productive status of the farms of two dairy cattle herds with a high incidence of anestric females belonging to a livestock company in the province of Camagüey, Cuba was performed on all animals the clinical-gynecological examination, the evaluation of the body condition, the determination of the live weight, a parasitological analysis and the evaluation of the metabolic state were used four groups of females: pregnant women in the last third (> 7½ months), recentins, between 15 and 20 days and 60 days of births and females with more than 60 days postpartum without being inseminated (empty), finally the evaluation of the availability of pastures and the consumption of dry matter in each of the herds was carried out . The data obtained were processed using the generalized linear model. The clinical-gynecological diagnosis showed problems with estrous cyclicity related to deficiencies in the detection of heat, high parasitic infestation (Fasciola hepatica), food problems and metabolic disorders (energy metabolism, protein, immune deficit, hypocalcemia and hypophosphoremia). The reproductive behavior of the herds and their state of health were related to the physical-productive state of the farms. It is recommended to improve the productive physical state of the farms to ensure an adequate forage balance and reproductive management in the herds based on the body condition and other health indicators of the female.Para determinar el estado reproductivo, metabólico, de salud y alimentario y evaluar el estado físico-productivo de las fincas de dos rebaños bovinos lecheros con elevada incidencia de hembras anéstricas pertenecientes a una empresa pecuaria de la provincia Camagüey, Cuba se realizó a todos los animales el examen clínico-ginecológico, la evaluación de la condición corporal, la determinación del peso vivo, un análisis parasitológico y la evaluación del estado metabólico fueron utilizados cuatro grupos de hembras: gestantes en el último tercio (> 7 ½ meses), recentinas, entre 15 y 20 días y de 60 días de paridas y hembras con mas de 60 días post parto sin ser inseminadas (vacías), por último se realizó la evaluación de la disponibilidad de los pastos y del consumo de materia seca en cada uno de los rebaños. Los datos obtenidos se procesaron mediante el modelo lineal generalizado. El diagnóstico clínico-ginecológico evidenció problemas con la ciclicidad estral relacionados con deficiencias en la detección del celo, alta infestación parasitaria (Fasciola hepatica), problemas alimentarios y desórdenes metabólicos (metabolismo energético, protéico, déficit inmunitario, hipocalcemia e hipofosforemia). El comportamiento reproductivo de los rebaños y su estado de salud estuvieron relacionados con el estado físico-productivo de las fincas. Se recomienda mejorar el estado físico productivo de las fincas para garantizar un balance forrajero adecuado y el manejo reproductivo en los rebaños sobre la base de la condición corporal y otros indicadores de salud de la hembra

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.We aimed to analyze the role of the common genetic variants located in the PIN1 locus, a relevant prolyl isomerase required to control the proliferation of spermatogonial stem cells and the integrity of the blood–testis barrier, in the genetic risk of developing male infertility due to a severe spermatogenic failure (SPGF). Genotyping was performed using TaqMan genotyping assays for three PIN1 taggers (rs2287839, rs2233678 and rs62105751). The study cohort included 715 males diagnosed with SPGF and classified as suffering from non-obstructive azoospermia (NOA, n = 505) or severe oligospermia (SO, n = 210), and 1058 controls from the Iberian Peninsula. The allelic frequency differences between cases and controls were analyzed by the means of logistic regression models. A subtype specific genetic association with the subset of NOA patients classified as suffering from the Sertoli cell-only (SCO) syndrome was observed with the minor alleles showing strong risk effects for this subset (ORaddrs2287839 = 1.85 (1.17–2.93), ORaddrs2233678 = 1.62 (1.11–2.36), ORaddrs62105751 = 1.43 (1.06–1.93)). The causal variants were predicted to affect the binding of key transcription factors and to produce an altered PIN1 gene expression and isoform balance. In conclusion, common non-coding single-nucleotide polymorphisms located in PIN1 increase the genetic risk to develop SCO.publishersversionpublishe
