Situational risk factors for fall-related vertebral fractures in older men and women.

Situational factors might help explain why most vertebral fractures occur in older people without a previous osteoporosis diagnosis. After adjusting for predisposing risk factors, the activity before the fall, type of fall, and falling direction remained as strong determinants of fall-related vertebral fractures in older men and women. INTRODUCTION: A matched case-control study was conducted to investigate the effects of situational factors, in addition to predisposing factors, on clinical vertebral fractures in older men and women in Taiwan. METHODS: Cases were community-dwelling individuals aged ≥ 65 years who visited emergency departments (EDs) of two university-affiliated hospitals due to a fall and had a primary diagnosis of a vertebral fracture during a 1-year period in 2017. Five control patients per case, matched by the time of falling, gender, and age, who sought care in the same ED due to a fall resulting in a soft tissue injury were selected. A total of 64 men (age range: 65 ~ 99 years) and 194 women (age range: 65 ~ 100 years), diagnosed with a vertebral fracture, participated in the study. RESULTS: Multivariable logistic models were conducted separately for men and women. Results suggested that the following factors were significantly associated with an increased risk of vertebral fractures in men: a low educational level (adjusted odds ratio [OR] = 1.95; 95% confidence interval (CI), 1.02 ~ 3.71), asthma (OR = 2.96; 95% CI, 1.35 ~ 6.92), depression (OR = 4.31; 95% CI, 1.03 ~ 17.5), toileting (OR = 2.30; 95% CI, 1.04 ~ 4.94), slipping (OR = 5.27; 95% CI, 1.80 ~ 15.4), stepping down (OR = 3.99; 95% CI, 1.40 ~ 11.4), sudden leg weakness (OR = 3.73; 95% CI, 1.13 ~ 12.4), and falling backwards (OR = 3.78; 95% CI, 1.83 ~ 7.80); and in women: a fracture history (OR = 2.00; 95% CI, 1.07 ~ 3.76), osteoporosis (OR = 1.94; 95% CI, 1.15 ~ 3.49), getting in/out of the bed/chair (OR = 1.90; 95% CI, 1.07 ~ 3.39), stepping down (OR = 2.10; 95% CI, 1.17 ~ 3.77), and falling backwards (OR = 4.00; 95% CI, 2.39 ~ 6.68) and sideways (OR = 2.61; 95% CI, 1.38 ~ 4.96). CONCLUSIONS: The combination of predisposing and situational risk factors may display a more comprehensive risk profile for the occurrence of VFs, and thus, interventions that add both types of risk factors may result in greater risk reduction of VFs, although those specifically targeted at situational risk factors during falls are limited and their effectiveness and efficiency remained to be explored.

Relations of osteoporosis and follow-up duration to recurrent falls in older men and women.

SUMMARY: There were differences in risk factors between men and women and between two follow-up time lengths. Osteoporosis was significantly associated with recurrent falls for women but not for men. The relationship of osteoporosis with falls in the past year decreased during follow-up, while those of sedatives and hypnotics remained. INTRODUCTION: A prospective study to investigate relationships between osteoporosis and recurrent falls at two follow-up lengths of 6 and 12 months in older men and women. METHODS: In total, 204 men and 447 women who visited an emergency department due to a fall were recruited. RESULTS: For men, the risk of falling was not significantly associated with osteoporosis at 6 or 12 months. Men with a fall history were 127 and 100 %, respectively, more likely to have a fall at 6 and 12 months than those without. Men who did not use walking aids were 97 % more likely to have a fall at 12 months than those who did. Women with osteoporosis were 246 and 104 %, respectively, more likely to have a fall at 6 and 12 months than those without. Women with a fall history were 129 and 66 %, respectively, more likely to have a fall at 6 and 12 months than those without. Women taking sedatives and hypnotics were 75 and 102 %, respectively, more likely to have a fall at 6 and 12 months than their counterparts. Women with depression were 138 % more likely to have a fall at 6 months and those using walking aids were 59 % more likely to have a fall at 12 months, compared to their counterparts. CONCLUSIONS: Osteoporosis is association with falls for older women but not for older men. Identifying risk factors for recurrent falls in older people may be affected by the follow-up length, as their associations are reduced over time.

Fall mechanisms, bone strength, and hip fractures in elderly men and women in Taiwan.

UNLABELLED: Three modifiable factors of fall direction, poor bone strength, and depression were associated with an increased risk of hip fractures for elderly men and women; fall direction was a much stronger predictor than the other two. When a fall occurs, changing fall direction may be most effective to prevent hip fractures. INTRODUCTION: A matched case-control study was conducted to identify risk factors for hip fractures in elderly men and women in Taiwan. METHODS: Cases were defined as persons who visited the emergency room due to a fall and were diagnosed with a first hip fracture. For each case, a control was matched by gender and time of falling, selected from persons who sought care at the same emergency room due to a fall resulting in injury other than a hip fracture. In total, 85 paired men and 221 paired women were included. RESULTS: For men, backward, straight-down, and sideways falls were associated with 10.8-, 13.6-, and 15.2-fold increased risks of hip fractures, respectively, compared with forward falls. Poor bone strength and depression were associated with 2.27- and 2.85-fold increased risks of hip fractures, respectively, while dependence in ≥3 activities of daily living was associated with a fivefold lower risk. For women, compared with forward falls, backward, straight-down, and sideways falls were associated with 10.2-, 9.86-, and 12.8-fold increased risks of hip fractures, respectively. Living in a rented house, poor bone strength, depression, and use of antidiabetics were associated with 1.65-, 2.78-, 1.89-, and 1.92-fold increased risks of hip fractures, respectively. Hormone replacement therapy was associated with a fivefold lower risk of hip fractures. CONCLUSIONS: While bone strength and depression can be risk factors for hip fractures in elderly people, the direction of the fall was the strongest predictor. Some risk factors differed between elderly men and women.

Crash severity, injury patterns, and helmet use in adolescent motorcycle riders.

BACKGROUND: This study examined crash severity and injury patterns between helmeted and unhelmeted adolescent motorcycle riders. METHODS: Among an initial population of 4,721 junior college students, 1,284 students were involved in 1,889 motorcycle crashes during a 20-month follow-up period. Crash severity was measured by both the type of collision object and the repair cost of motorcycle damage. RESULTS: The incidence rates of crash, injury, hospitalization, and deaths per 1,000 person-years in the cohort were 358, 104, 14, and 1.3, respectively. Compared with helmeted riders, unhelmeted riders had more noncollisions and fewer collisions with a moving car but there was no significant difference in repair cost of motorcycle damage between these groups. More injuries to the external skin, face, and head and more severe injuries occurred in unhelmeted than in helmeted riders. Among crashes resulting in hospitalization/death, more injuries to the face and head occurred in unhelmeted riders than in helmeted riders. CONCLUSION: Crashes involving unhelmeted riders were not more severe but more frequently involved face and head injuries than crashes involving helmeted riders.

Patient and family adjustment to heart transplantation.

Heart transplantation is an effective treatment for end-stage cardiac disease and a major stressor to patients and their families. The purpose of this paper is to review the literature on patient and family adjustment to heart transplantation during the stages from pre-transplantation to post-transplantation. Most authors indicate that patients and families adjust well to heart transplantation. Support groups are a positive resource for heart transplant patients and their families.
