Breastfeeding and ovarian cancer risk: a systematic review and meta-analysis of 40 epidemiological studies
jekas [21]

Breastfeeding and ovarian cancer risk: a systematic review and meta-analysis of 40 epidemiological study shows that:

The present systematic review and meta-analysis was conducted to assess any association between breastfeeding and the risk of ovarian cancer.

A systematic search of published studies was performed in PUBMED and EMBASE and by reviewing reference lists from retrieved articles through March 2013.

Data extraction was conducted independently by two authors. Pooled relative risk ratios were calculated using random-effect models.

Total of 5 cohort studies and 35 case-control studies including 17,139 women with ovarian cancer showed a 30% reduced risk of ovarian cancer when comparing the women who had breastfed with those who had never breastfed (pooled RR = 0.70, 95% CI: 0.64-0.76; p = 0.00), with significant heterogeneity in the studies (p = 0.00; I2 = 76.29%).

A significant decreasd in risk of epithelial ovarian cancer was also observed (pooled RR = 0.68, 95% CI: 0.61-0.76).

When the participants were restricted to only parous women, there was a slightly attenuated but still significant risk reduction of ovarian cancer (pooled RR = 0.76, 95% CI: 0.69-0.83).

For total breastfeeding duration, the pooled RRs in the < 6 months, 6-12 months and > 12 months of breastfeeding subgroups were 0.85 (95% CI: 0.77-0.93), 0.73 (95% CI: 0.65-0.82) and 0.64 (95%CI: 0.56-0.73), respectively.

Meta-regression of total breastfeeding duration indicated an increasing linear trend of risk reduction of ovarian cancer with the increasing total breastfeeding duration (p = 0.00).

Breastfeeding was inversely associated with the risk of ovarian cancer, especially long-term breastfeeding duration that demonstrated a stronger protective effect.

Answer:

D )

Explanation:

¿Cuál es el propósito y el objetivo de las iniciativas de acreditación de

JCI?

La acreditación de JCI es una variedad de iniciativas elaboradas para responder a la creciente demanda

existente en todo el mundo de una evaluación de la atención sanitaria basada en estándares. El propósito es

ofrecer a la comunidad internacional procesos objetivos basados en estándares para la evaluación de las

organizaciones sanitarias. El objetivo del programa es estimular la demostración de mejoras constantes y

sostenidas en las organizaciones sanitarias, mediante la aplicación de estándares internacionales

generalizados, Objetivos Internacionales para la Seguridad del Paciente y el respaldo de medidas de

indicadores. Además de los estándares contenidos en esta cuarta edición para hospitales de atención aguda,

JCI ha elaborado estándares y programas de acreditación para:

• Laboratorios de análisis clínicos

• La atención continuada (atención domiciliaria, asilos, cuidados a largo plazo, cuidados paliativos)

• Organizaciones de transporte médico

• Atención Ambulatoria

JCI también ofrece certificación de programas que proporcionan atención específica para una enfermedad o

trastorno, como programas de atención de accidentes cerebrovasculares o atención cardíaca.

Los programas de acreditación de JCI están basados en un marco internacional de estándares adaptables a las

necesidades locales. Los programas se caracterizan por:

• Los estándares internacionales generalizados, elaborados y mantenidos por un grupo de trabajo

internacional y aprobados por un Consejo Internacional, siendo la base del programa de acreditación.

• La filosofía subyacente de los estándares está basada en los principios de gestión de la calidad y de

mejora continua de la calidad.

• El proceso de acreditación está diseñado para dar cabida a los factores jurídicos, religiosos y/o culturales

dentro de un país. Si bien los estándares establecen expectativas altas y uniformes para la seguridad y la

calidad de la atención al paciente, las consideraciones específicas de cada país relacionadas con el

cumplimiento de dichas expectativas forman parte del proceso de acreditación.

• Los miembros del equipo evaluador y la agenda pueden variar, dependiendo del tamaño de la

organización y del tipo de servicios que preste. Por ejemplo, un hospital escuela grande requerirá una

evaluación de cuatro días realizado por un médico, una enfermera y un administrador, mientras que un

hospital regional o comunitario más pequeño quizá requiera una evaluación de dos o tres días. En forma

similar, un laboratorio clínico requerirá de una sola persona, durante tan solo dos días, dependiendo de

la cantidad de análisis especializados que se ofrezcan y realicen.

• La acreditación de JCI está diseñada para ser válida, confiable y objetiva. Según el análisis de las

conclusiones del estudio, un comité internacional de acreditación tomará las decisiones definitivas sobre

la acreditación.

How do the oomycetes differ from other stramenopiles, and what are some important plant diseases caused by oomycetes
AlladinOne [14]

Answer:

OBJECTIVES:

To observe symptoms and signs of representative diseases caused by the Oomycete pathogens.

To become familiar with vegetative and reproductive structures of the Oomycetes, and their role in disease development.

INTRODUCTION:

The Oomycetes, also known as water molds, are a large group of terrestrial and aquatic eukaryotic organisms. Although they superficially resemble fungi in mycelial growth and mode of nutrition, molecular studies and distinct morphological characteristics place them in the kingdom Chromalveolata (phylum Heterokontophyta, the 'stramenopiles') with brown and golden algae and diatoms.

The nurse administers cimetidine to a 75-year-old client diagnosed with a gastric ulcer. the nurse should monitor the client for
Finger [1]

The nurse administers cimetidine to a 75-year-old client diagnosed with a Gastric ulcer the nurse should monitor the client for the following adverse reactions Headache, Sleepiness, Confusion, Dizziness, Nausea which contribute for the change in Metal status.

  • Cimetidine is a H2\\ Receptor Antagonist.
  • Gastric partial cells contains receptors for Histamine.
  • Histamine is released from the Enterochromaffin cells upon the stimulation from food intake or from Vagus nerve stimulation.
  • Thus Histamine released from Enterochromaffin cells binds to H2\\ receptors on the parietal cells and increases the secretion of HCl.
  • Cimetidine has totally opposite effect and decreases the secretion of HCl from the parietal cells.
  • Not only on gastric cells H2\\ receptors are also present in CNS where they stimulate brain cells.
  • The above point justifies the adverse effects of Cimetidine.
  • Patients over the age of 50 or those who are severely ill may experience transient confusion while taking H2 blockers, particularly cimetidine.

Hence from these points we can conclude that patients who are above 50 years and receiving Cimetidine medication for gastric ulcer should be monitored for the above mentioned adverse reactions.
