Background: Orthopedics is not a popular field of specialization among female medical students. Therefore, the purpose of the study was to examine factors related to women's choice of orthopedics as their field of specialty, compared to those who chose other fields. Methods: In this cross-sectional survey, 149 female medical residents from Israel—33 specializing in orthopedics and 116 in other fields—completed a questionnaire. A comparison was held between the two groups. Results: Orthopedic residents were more likely to have received clinical training in this field during their medical studies and were more likely to have expressed a desire to specialize in orthopedics before and at the completion of their studies. In addition, orthopedic residents ascribed greater importance to job security when choosing a field of specialty and, in contrast, ascribed no importance at all to lifestyle. No difference was found between the two groups in their level of dissatisfaction as a result of their residency. However, orthopedic residents were more inclined to perceive gender discrimination in the field of orthopedics but, despite this, had a greater intention to recommend a residency in orthopedics. A negative association was found between the level of dissatisfaction as a result of the residency and intention to recommend a residency in orthopedics. Conclusions: Differences between the two groups point to potential factors that might have been related to women's choice of orthopedics as their field of specialty. The findings may help form strategies for attracting women to specialize in orthopedics. [ABSTRACT FROM AUTHOR]

Background: It is unclear whether climate may play a role in the association between hyponatremia on admission and increased mortality risk among hip fracture patients following a hip fracture repair surgery. We aimed (1) to explore if there is any combined effect of seasonality and hyponatremia on the occurrence of hip fractures among older adults and (2) to explore the effect of hyponatremia on admission on mortality rate at latest follow-up among hip fracture patients following a hip fracture repair surgery in the context of the subtropical climate of Israel. Methods: We conducted a retrospective cohort study of older patients who underwent a surgery for hip fracture repair in a major 495-bed hospital located in northern-central Israel in 2017–2020. Patients were divided into two groups: hyponatremic (n = 107) and normonatremic (n = 757) patients. Characteristics of the two groups were compared, as well as their survival probability. Results: Hyponatremic patients were most frequently hospitalized during winter season. Such seasonal variation was observed only among hyponatremic patients. Moreover, patients who were hospitalized during winter season were more likely to be hyponatremic on admission. Hyponatremia on admission was found as a significant independent predictor of mortality rate at latest follow-up (adjusted hazard ratio = 0.377 [0.26–0.52]), when compared to normonatremia. Conclusion: There is a combined effect of seasonality and hyponatremia on the occurrence of hip fractures among older adults, with hyponatremic patients being at a higher risk of sustaining a hip fracture during winter season than during other seasons. In addition, the association between hyponatremia on admission and mortality rate at latest follow-up among hip fracture patients has been confirmed. [ABSTRACT FROM AUTHOR]

Background/Aims: In our previous study, impaired visually evoked flow velocity response was demonstrated in young chronic smokers. Our aim was to study whether impaired cerebrovascular reactivity is reversible 6–18 months after smoking cessation. Methods: Flow velocity changes, evoked by visual stimulus, were recorded in the posterior cerebral arteries in 15 smokers, 15 former smokers and 15 nonsmokers. The stimulation protocol consisted of 10 cycles with a resting phase of 20 s (baseline) and a stimulating phase of 40 s for each cycle. Relative changes of flow velocity were expressed in relation to baseline. Breath holding index, visual evoked potential and intima-media thickness were also examined. Results: Repeated measures ANOVA revealed marked difference in the flow velocity time courses between the 3 groups (p < 0.01). The flow response was significantly worse in former smokers than in nonsmokers (p < 0.002), however, no significant difference was found between former and current smokers (p = 0.0556). Conclusion: This is the first transcranial Doppler study demonstrating long-term impairment of visually evoked cerebrovascular response after smoking cessation. These findings indicate that the impairment of neurovascular coupling caused by smoking is due to structural changes of the vessels, rather than acute effect of smoking. Copyright © 2009 S.

Different methods are used to assess the vasodilator ability of cerebral blood vessels; however, the exact mechanism of cerebral vasodilation, induced by different stimuli, is not entirely known. Our aim was to investigate whether the potent vasodilator agent, acetazolamide (AZ), inhibits the neurovascular coupling, which also requires vasodilation. Therefore, visually evoked flow parameters were examined by transcranial Doppler in ten healthy subjects before and after AZ administration. Pulsatility index and peak systolic flow velocity changes, evoked by visual stimulus, were recorded in the posterior cerebral arteries before and after intravenous administration of 15 mg/kg AZ. Repeated-measures ANOVA did not show significant group main effect between the visually evoked relative flow velocity time courses before and after AZ provocation (P=0.43). Visual stimulation induced significant increase of relative flow velocity and decrease of pulsatility index not only before but also at the maximal effect of AZ. These results suggest that maximal cerebral vasodilation cannot be determined by the clinically accepted dose of AZ (15 mg/kg) and prove that neurovascular coupling remains preserved despite AZ-induced vasodilation. Our observation indicates independent regulation of vasodilation during neurovascular coupling, allowing the adaptation of cerebral blood flow according to neuronal activity even if other processes require significant vasodilation.

This study examines factors associated with screening of female patients for intimate partner violence (IPV) by orthosurgeons in a sample of 100 Israeli orthosurgeons. Findings reveal positive attitudes toward screening female patients but a significant lack of knowledge. Arab orthosurgeons held slightly more negative attitudes toward screening for IPV and had a more prominent lack of knowledge regarding screening for IPV, compared to their Jewish counterparts. Nationality and feeling uncomfortable asking female patients about IPV predicted screening for IPV. The importance of training orthosurgeons on the assessment and treatment of IPV cannot be overemphasized, especially among Arab orthosurgeons. [ABSTRACT FROM AUTHOR]

Searching for clinical manifestations of elder abuse may help healthcare professionals identify cases of elder abuse. The aim of the present study was to explore characteristics of older patients with fractures that increase the likelihood that the fracture was associated with abuse. This is a retrospective chart review study of 1,000 patients aged 65 and older who presented to an emergency department in northern-central Israel with a fracture during 2019. The chart review included participant characteristics – sociodemographic data, medical data, data regarding the fracture, and data on the presence of forensic markers of elder abuse in individual patients. Descriptive statistics and regression models were used for the analyses. Older age, presence of dementia, and hand and facial fractures were associated with the presence of forensic markers, and were also found to predict having at least one forensic factor. This study provides further support for the creation of clinical guidelines for identification of elder abuse. [ABSTRACT FROM AUTHOR]
