Antenatal anxiety symptoms are not only a health problem for the expectant mother. Research has found that maternal anxiety may also have an impact on the developing baby. Therefore, it is important to estimate the prevalence of maternal anxiety and associated factors. The current study aims to estimate the prevalence of anxiety symptoms during the first trimester of pregnancy and to identify associated risk factors. Secondly, to investigate other factors associated with anxiety during early pregnancy including fear of childbirth and a preference for cesarean section. In a population-based community sample of 1,175 pregnant women, 916 women (78%) were investigated in the first trimester (gestation week 8-12). The Hospital Anxiety Depression Scale (HADS-A) was used to measure anxiety symptoms. The prevalence of anxiety symptoms (HADS-A scores≥8 during pregnancy) was 15.6% in early pregnancy. Women under 25 years of age were at an increased risk of anxiety symptoms during early pregnancy (OR 2.6, CI 1.7-4.0). Women who reported a language other than Swedish as their native language (OR 4.2, CI 2.7-7.0), reported high school as their highest level of education (OR 1.6, CI 1.1-2.3), were unemployed (OR 3.5, CI 2.1-5.8), used nicotine before pregnancy (OR 1.7, CI 1.1-2.5), and had a self-reported psychiatric history of either depression (OR 3.8, CI 2.6-5.6) or anxiety (OR 5.2, CI 3.5-7.9) before their current pregnancy were all at an increased risk of anxiety symptoms during early pregnancy. Anxiety symptoms during pregnancy increased the rate of fear of birth (OR 3.0, CI 1.9-4.7) and a preference for cesarean section (OR 1.7, CI 1.0-2.8). Caregivers should pay careful attention to history of mental illness to be able to identify women with symptoms of anxiety during early pregnancy. When presenting with symptoms of anxiety, the women might need counseling and or treatment in order to decrease her anxiety.
Apparent regeneration of the tendons of the semitendinosus and gracilis muscles after their use for anterior cruciate ligament reconstruction was noted during routine follow-up of 225 patients. From this group, four patients were selected for thorough examination, including magnetic resonance imaging, electromyographic studies, strength testing, and clinical examination. The results demonstrate that these tendons appear to regrow and are probably functional.
Return to regular sports activity was evaluated in a retrospective review of 160 patients who had undergone total knee replacement surgery by a single surgeon (208 knee replacements). Mean age of the patients was 68 years (range, 27 to 87) at surgery and 73 years (range, 33 to 91) at review at a mean follow-up of 5 years (range, 3 to 7). Seventy-nine patients regularly participated in sports, at least once per week, before surgery, and 51 patients regularly participated in sports after surgery. Only eight patients took up sports after surgery who were not regularly involved in sports in the year before surgery. Patients were more likely to return to low-impact activities such as bowls (29 of 32, or 91%) than to high-impact activities such as tennis (6 of 30, or 20% returned). Forty-three of 56 patients (77%) who had participated in regular exercise in the year before surgery returned to sports. Eighty patients did not participate in sports before surgery and 54 of these had coexisting disease that prevented sports. None of these patients returned to sports.
The functional anatomy of tha anterior cruciate ligament was studied in 18 freshly amputated specimens. The cruciates were observed in the extremes of flexion and extension, and in midposition in simulated weight-bearing and nonweight-bearing conditions. Five femoral shafts were split longitudinally so that the femoral and tibial attachments of the ligament could be inspected. The findings indicated that (1) the anterior cruciate ligament is a secondary static stabilizer against rotatory instabilities of the knee; (2) the anteromedial bundle contributes to anterolateral stability; (3) the intermediate bundle adds to straight and anteromedial stability; and (4) the posterolateral bundle assists in posterolateral stability. Specific bundles and functions of bundles must be considered in reconstruction, substitution, or replacement of the anterior cruciate ligament.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
