Factors Associated with the Cessation of Intimate Partner Violence in Women Attending Primary Care in Spain

This study aimed to identify factors associated with the likelihood of IPV cessation among women attending Spanish primary healthcare. Of the 2465 women who reported lifetime IPV, 36.1 % stated that violence had ceased. Those women not currently abused had higher levels of education and social support, were workers or students, and had no dependent children. When IPV duration was less than 5 years, the likelihood of cessation was two times higher than when IPV continued beyond 5 years. For women who have experienced physical IPV, the probability of ending the violent relationship was 10 times higher than for those suffering from psychological IPV. The implications of the findings regarding clinical significance and future research are discussed.

Factors Associated With Women’s Reporting of Intimate Partner Violence in Spain

In Spain, in 2013, the 20% of women who were murdered by their partner had reported him previously. We analyze the 2011 Spanish-Macrosurvey on Gender Violence to identify and analyze the prevalence of and the principal factors associated with reporting a situation of intimate partner violence (IPV) and the main reasons women cite for not filing such reports, or for subsequently deciding to withdraw their complaint. Overall, 72.8% of women exposed to IPV did not report their aggressor. The most frequent reasons for not reporting were not giving importance to the situation (33.9%), and fear and lack of trust in the reporting process (21.3%). The main reasons for withdrawing the complaint were cessation of the violence (20.0%), and fear and threats (18.2%). The probability of reporting increased among women with young children who were abused, prevalence ratio (95% confidence interval [CI]): 2.14 [1.54, 2.98], and those whose mother was abused, prevalence ratio (95% CI): 2.25 [1.42, 3.57]. Always focusing on the need to protect women who report abuse, it is necessary to promote the availability of and access to legal resources especially among women who use them less: women who do not have children and women who do not have previous family exposure to violence.

Errors Associated to Keratoconus Grading using Systems based on Corneal Power

Purpose: To analyze and define the possible errors that may be introduced in keratoconus classification when the keratometric corneal power is used in such classification. Materials and methods: Retrospective study including a total of 44 keratoconus eyes. A comprehensive ophthalmologic examination was performed in all cases, which included a corneal analysis with the Pentacam system (Oculus). Classical keratometric corneal power (Pk), Gaussian corneal power (Pc Gauss), True Net Power (TNP) (Gaussian power neglecting the corneal thickness effect), and an adjusted keratometric corneal power (Pkadj) (keratometric power considering a variable keratometric index) were calculated. All cases included in the study were classified according to five different classification systems: Alió-Shabayek, Amsler-Krumeich, Rabinowitz-McDonnell, collaborative longitudinal evaluation of keratoconus (CLEK), and McMahon. Results: When Pk and Pkadj were compared, differences in the type of grading of keratoconus cases was found in 13.6% of eyes when the Alió-Shabayek or the Amsler-Krumeich systems were used. Likewise, grading differences were observed in 22.7% of eyes with the Rabinowitz-McDonnell and McMahon classification systems and in 31.8% of eyes with the CLEK classification system. All reclassified cases using Pkadj were done in a less severe stage, indicating that the use of Pk may lead to the classification of a cornea as keratoconus, being normal. In general, the results obtained using Pkadj, Pc Gauss or the TNP were equivalent. Differences between Pkadj and Pc Gauss were within ± 0.7D. Conclusion: The use of classical keratometric corneal power may lead to incorrect grading of the severity of keratoconus, with a trend to a more severe grading.

Fatores associados ao abandono do aleitamento materno durante os primeiros seis meses de vida

O objetivo da pesquisa foi identificar os fatores associados ao abandono do aleitamento materno (AM) e do aleitamento materno completo (AMC). Foram acompanhadas 248 mães que fizeram visita pós-parto. Os dados foram coletados mediante entrevista pessoal durante o primeiro mês pós-parto e, pelo telefone, aos quatro e seis meses seguintes. A análise se realizou mediante a Regressão de Cox. Os resultados mostram associação entre o abandono da AMC e do AM com o fato de não se ter amamentado anteriormente, com AM anterior ≤4 meses, e, com pior avaliação da experiência anterior. O menor nível de estudos se relaciona com maior abandono do AM e das chupetas, ou suplementos no hospital com o abandono da AMC. A educação pré-natal é fator protetor para o AMC e o AM. Conclui-se que o apoio ao AM deveria intensificar-se nas mães: sem experiência anterior, com experiência negativa, e, com pior acesso à informação; também deveria ser controlado o uso da chupeta e dos suplementos de leite artificial (LA) não indicados.

Análisis numérico del comportamiento vibratorio del conjunto móvil de un altavoz dinámico

En este trabajo se describe el proceso llevado a cabo para analizar numéricamente mediante el método de los elementos finitos (MEF) el comportamiento vibratorio del conjunto móvil de un altavoz dinámico de bobina con doble suspensión inferior y en ausencia de la superior. El estudio se centra en el rango de baja frecuencia. El calibrado del modelo se realiza en base a medidas experimentales de la frecuencia de resonancia y desplazamiento del diafragma. Se hace énfasis en la importancia de los factores de participación asociados a la fuerza de excitación y en los cambios que se producen en estos al introducir fuerzas no equilibradas. Así mismo, el análisis proporciona datos para decidir sobre la distancia entre suspensiones, su número óptimo de pliegues y la ubicación de las trencillas, siendo estos parámetros de gran interés en el diseño de este tipo de altavoces.
