Evaluation of the Association between Pelvic Diameters and Pelvic Types on Computed Tomography Images in Healthy Turkish Females / Evaluación de la Asociación entre Diámetros Pélvicos y Tipos de Pelvis en Imágenes de Tomografías Computarizadas en Mujeres Turcas Sanas

SUMMARY: Pelvis contributes to both human locomotion and obstetrics, and normal vaginal delivery is associated with a spacious inlet, a large interspinosus diameter. This paper aimed to measure crucial diameters of pelvic ring, and to determine both the prevalence of pelvic types, and labor types including normal vaginal delivery or caesarean section in Turkish healthy females. Additionally, it was aimed to evaluate presence of relationship between pelvic types and pelvic diameters. Labor shape of subjects was obtained from hospital records. This retrospective study was carried out on 165 healthy subjects aged between 18 and 45 years. Anteroposterior diameter of the pelvic inlet (APDI), anteroposterior diameter of the pelvic outlet, sacrum length (SL), sacrum depth, conjugata vera, obstetrical conjugate, the diagonal conjugate, diameter transversa, diameter bispinous, intertuberous diameter were measured. From these measurements, brim index was calculated and decided to gynecoid, anthropoid and platypelloid type. Also, the andoid type was calculated to the ratio of posterior sagittal diameter of the inlet to conjugata obstetrica. 50.91 % of participants has gynecoid type pelvis, followed by 24.85 % anthropoid type, 14.55 % platypelloid, and 9.70 % android type pelvis. There was a significant difference in APDI, SL, SD, Conjugata vera, Conjugata obstetrica, Conjugata diagonalis, Conjugata transversa, diameter bispinous, diameter intertubercularis and Brim index measurements according to pelvic types. the first degree of narrowing (conjugata vera from 11 to 9) was found in 18 pelvises and 12 pelvises with the pathological degree of narrowing bellonged to the platypelloid type followed by android type pelvis with 6 pelvices. The android type pelvis is not appropriate for natural labor and a good assessment of birth canal can reduce the labor risks. Also, only 7 females who delivered with cesarean have gynecoid type pelvic type. The APDI and SL were significantly lower in subjects having pathological narrowing according to conjugata obstetrica values.

La pelvis contribuye tanto a la locomoción humana como a la obstetricia. El parto vaginal normal se asocia con una entrada espaciosa y un diámetro interespinoso grande. Este artículo tuvo como objetivo medir diámetros cruciales del anillo pélvico y determinar tanto la prevalencia de los tipos pélvicos como los tipos de parto, incluido el parto vaginal normal o la cesárea en mujeres turcas sanas. Además, se buscó evaluar la presencia de relación entre los tipos de pelvis y los diámetros de la pelvis. La forma laboral de los sujetos se obtuvo de los registros hospitalarios. Este estudio retrospectivo se llevó a cabo en 165 mujeres sanas con edades comprendidas entre 18 y 45 años. Se midieron el diámetro anteroposterior de la entrada pélvica (APDPI), el diámetro anteroposterior de la salida pélvica, la longitud del sacro (SL), la profundidad del sacro, la conjugada vera, el conjugado obstétrico, el conjugado diagonal, el diámetro transverso, el diámetro biespinoso y el diámetro intertuberoso. A partir de estas mediciones se calculó el índice del ala y se decidió tipo ginecoide, antropoide y platipoide. Además, el tipo androide se calculó en función de la relación entre el diámetro sagital posterior de la entrada y la conjugada obstétrica. El 50,91 % de los participantes tenía pelvis de tipo ginecoide, seguida del 24,85 % de pelvis de tipo antropoide, el 14,55 % de tipo platipeloide y el 9,70 % de tipo androide. Hubo una diferencia significativa en las mediciones de APDPI, SL, SD, Conjugada vera, Conjugada obstétrica, Conjugada diagonal, Conjugata transversa, diámetro biespinoso, diámetro intertubercular e índice de ala según los tipos de pelvis. El primer grado de estrechamiento (conjugada vera del 11 al 9) se encontró en 18 pelvis y 12 pelvis, siendo el grado patológico de estrechamiento del tipo platipeloide seguido de pelvis tipo androide con 6 pelvis. La pelvis tipo androide no es apropiada para el parto natural y una buena evaluación del canal del parto puede reducir los riesgos. Además, solo 7 mujeres que dieron a luz por cesárea tenían un tipo pélvico de tipo ginecoides. El APDPI y SL fueron significativamente más bajos en mujeres que tenían estrechamiento patológico según los valores obstétricos conjugados.

Evaluation of the Association Between Carrying Angle, Hand Grip Strength, Lateral Pinch Strength, and Hand Functional Index in Nursing Students / Evaluación de la Asociación entre el Ángulo de Carga, la Fuerza de Agarre de la Mano, la Fuerza de Pellizco Lateral y el Índice Funcional de la Mano en Estudiantes de Enfermería

SUMMARY: Health professionals especially nurses have ongoing contact with patients and they may have a high incidence of musculoskeletal problems. For this reason, grip strength and carrying angle are important parameters for all health professionals to succeed in their job and avoid injuries. It was aimed to determine the effects of the hand grip, and pinch strength, carrying angle of dominant, and non-dominant hands as well as the association of the hand functional index with morphometric measurements in 193 nursing students. The means of the carrying angle of dominant and non-dominant sides were 169.11±4.21° and 168.16±4.30°, respectively. The means of the dominant and, non-dominant sides of hand grip strength were 45.99±11.24 kg and 45.89±11.34 kg, respectively. The lateral pinch strength means were measured as 19.55±3.75 kg and 19.31±3.45 kg, respectively. This paper's findings may be important for some experts such as anatomists, clinicians, surgeons, forensic scientists, anthropologists, and nurses- healthcare professionals keep in touch with patients. Also, we believe that appropriate and effective knowledge of carrying angle, hand grip and lateral pinch strength has created an opportunity to research in terms of reducing work-related risk factors.

Los profesionales de la salud, especialmente las enfermeras, se mantienen en contacto con los pacientes y pueden tener una alta incidencia de problemas musculo-esqueléticos. En consecuencia, la fuerza de agarre y el ángulo de carga son parámetros importantes para que todos los profesionales de la salud tengan éxito en su trabajo y eviten las lesiones. El objetivo de este estudio fue determinar los efectos de la fuerza de prensión y pinzamiento de la mano, el ángulo de carga de las manos dominantes y no dominantes, así como la asociación del índice funcional de la mano con medidas morfométricas en 193 estudiantes de enfermería. Las medias del ángulo de carga de los lados dominante y no dominante fueron 169,11±4,21° y 168,16±4,30°, respectivamente. Las medias de los lados dominante y no dominante de la fuerza de prensión manual fueron 45,99 ± 11,24 kg y 45,89 ± 11,34 kg, respectivamente. La media de la fuerza de pellizco lateral se midió como 19,55 ± 3,75 kg y 19,31 ± 3,45 kg, respectivamente. Los hallazgos de este artículo pueden ser importantes para algunos expertos, como anatomistas, médicos clínicos, cirujanos, científicos forenses, antropólogos y enfermeras y profesionales de la salud que se mantienen en contacto con los pacientes. Además, creemos que el conocimiento apropiado y efectivo del ángulo de carga, el agarre de la mano y la fuerza de pellizco lateral ha creado una oportunidad para investigar en términos de reducción de los factores de riesgo relacionados con el trabajo.

Crista Galli Morphometry and Morphology: An Anatomical, Radiological, and Machine Learning Application Study / Crista Galli Morfometría y Morfología: Un Estudio de Aplicación Anatómica, Radiológica y de Aprendizaje Automático

SUMMARY: The study purposed to examine the morphometry and morphology of crista galli in cone beam computed tomography (CBCT) and apply a new analysis, supervised Machine Learning techniques to find the answers to research questions "Can sex be determined with crista galli morphometric measurements?" or "How effective are the crista galli morphometric measurements in determining sex?". Crista galli dimensions including anteroposterior, superoinferior, and laterolateral were measured and carried out on 200 healthy adult subjects (98 females; 102 males) aged between 18-79 years. Also, crista galli was classified with two methods called morphological types and Keros classification. In this study, the Chi-square test, Student's t-test, and Oneway ANOVA were performed. Additionally, Machine Learning techniques were applied. The means of the CGH, CGW, and CGL were found as 14.96 mm; 3.96 mm, and 12.76 mm in males, respectively. The same values were as 13.54 mm; 3.51 mm and 11.59±1.61 mm in females, respectively. The CG morphometric measurements of males were higher than those of females. There was a significant difference between sexes in terms of morphological classification type. Also, when the sex assignment of JRip was analyzed, out of 102 male instances 62 of them were correctly predicted, and for 98 female instances, 70 of them were correctly predicted according to their CG measurements. The JRip found the following classification rule for the given dataset: "if CGH<=14.4 then sex is female, otherwise sex is male". The accuracy of this rule is not high, but it gives an idea about the relationship between CG measurements and sex. Although the issue that CG morphometric measurements can be used in sex determination is still controversial, it was concluded in the analysis that CG morphometric measurements can be used in sex determination. Also, Machine Learning Techniques give an idea about the relationship between CG measurements and sex.

En el estudio se propuso examinar la morfometría y la morfología de la crista galli del hueso etmoides usando tomografía computarizada de haz cónico (CBCT) y aplicar un nuevo análisis, técnicas de aprendizaje automático supervisado para encontrar las respuestas a las preguntas de investigación "¿Se puede determinar el sexo con mediciones morfométricas de la crista galli?" o "¿Qué tan efectivas son las medidas morfométricas de la crista galli para determinar el sexo?". Las dimensiones de la crista galli, incluidas los diámetros anteroposterior, superoinferior y laterolateral, se midieron y realizaron en 200 sujetos adultos sanos (98 mujeres; 102 hombres) con edades comprendidas entre los 18 y los 79 años. La crista galli se clasificó con dos métodos llamados tipos morfológicos y clasificación de Keros. En este estudio, se realizaron la prueba de Chicuadrado, la prueba t de Student y ANOVA de una vía. Adicionalmente, se aplicaron técnicas de Machine Learning. Las medias de CGH, CGW y CGL se encontraron en 14,96 mm; 3,96 mm y 12,76 mm en hombres, respectivamente. Los mismos valores fueron 13,54 mm; 3,51 mm y 11,59 ± 1,61 mm en mujeres, respectivamente. Las medidas morfométricas del CG de los hombress fueron más altas que las de las mujeres. Hubo una diferencia significativa entre sexos en cuanto al tipo de clasificación morfológica. Además, cuando se analizó la asignación de sexo de JRip, de 102 instancias masculinas, 62 de ellas se predijeron correctamente, y de 98 instancias femeninas, 70 de ellas se predijeron correctamente de acuerdo con las mediciones de CG. El JRip encontró la siguiente regla de clasificación para el conjunto de datos dado: "si CGH<=14.4, por tanto el sexo es femenino, de lo contrario, el sexo es masculino". La precisión de esta regla no es alta, pero da una idea de la relación entre las medidas del CG y el sexo. Aunque la pregunta si las medidas morfométricas CG se pueden usar en la determinación del sexo sigue aún siendo controvertida. Se concluyó en el análisis que las medidas morfométricas CG se pueden usar en la determinación del sexo. Además, las técnicas de aprendizaje automático dan una idea de la relación entre las medidas de CG y el sexo.

It included 103 patients with spinal cord injuries.Outcome Measures: The data were collected using an introductory information form, the American Spinal Injury Association Impairment Scale and the Golombok Rust Inventory of Sexual Satisfaction. Data were evaluated using the chi-square test, the Mann-Whitney U test, the Kruskal-Wallis test and linear regression.Results: The total mean scores on the Golombok Rust Inventory of Sexual Satisfaction were 40.2 ± 21.6 for males and 44.9 ± 18.1 for females. According to the linear regression analysis, model VII presented the best results of the relationship between physiological and psychological determinants that affect the sexual satisfaction of patients with spinal cord injuries. Model VII consisted of the variables of ASIA A and B scores, age, injury due to falling from height, being a housewife, and thinking of being unable to reach future goals. These explained 75.4% of the variation in sexual satisfaction scores.Conclusion: The participants' mean scores on the Golombok Rust Inventory of Sexual Satisfaction were found to be affected by various variables. A significant relationship between their mean scores on the American Spinal Injury Association (ASIA) Impairment Scale and the Golombok Rust Inventory of Sexual Satisfaction was determined.

Adaptation of the Lawton Instrumental Activities of Daily Living Scale to Turkish: Validity and Reliability Study.

BACKGROUND: The Lawton Instrumental Activities of Daily Living (IADL) scale is the most widely used scale for the assessment of IADL in the elderly population. The aim of this study was to adapt the Lawton IADL Scale in Turkish and to investigate the validity and the reliability of the scale in older adults. METHODS: A total of 80 participants with a mean age of 71.6±5.8 years were included in the study. The independent living skills of the older adults were measured using Lawton IADL, Hodkinson Mental Test, Functional Independence Scale, Barthel Index, Katz Index, and visual analog scale. Lawton IADL was translated into Turkish, validated by professional reviewers, translated back into English, and then tested. Cronbach's alpha was used to measure reliability in a group of 34 participants and test-retest was performed 1 week after the first test. Pearson correlation analysis was used to show the relationship between Lawton IADL and other scales and indexes. RESULTS: Internal consistency (Cronbach's alpha) value was 0.843 for the whole scale. The intraclass correlation coefficient value of the scale was 0.915. CONCLUSION: These results confirm that the Turkish version of the Lawton IADL scale has excellent reliability and validity.
