RESUMEN
OBJECTIVES: To assess all-cause mortality and suicides after pediatric traumatic brain injury (pTBI). STUDY DESIGN: We conducted population-based historical cohort study using three nationwide registers from 1998 to 2018 in Finland. All patients that were the age of 0-17 at the time of the pTBI were included. The reference group consisted of children with ankle or wrist fractures. We used Kaplan-Meier and restricted mean survival time (RMST) analysis with 95% confidence intervals (CI) to compare all-cause mortality and suicides between groups. RESULTS: After 20 years of follow-up, there were 479 deaths in the pTBI group (0.67% of 71,963) and 306 deaths in the reference group (0.47% of 64,848). In the pTBI group, 28.6% of the deaths occurred after the first follow-up year, compared to 2.6% in the reference group. In all-cause mortality, survival time was slightly less in the pTBI group with age and gender adjustment throughout the follow-up period [20-year RMST ratio: 0.995; CI (0.994-0.996)]. The leading manners of death were suicides (pTBI group = 28.4%; reference group = 45.5%) and traffic collisions (pTBI group = 37.4%; reference group = 20.8%). Age and gender-adjusted survival time was slightly less for those with suicide as a manner of death in the pTBI group [10-year RMST ratio: 0.999; CI (0.999-0.999); 20-year RMST ratio: 0.999; CI (0.998-0.999)]. CONCLUSIONS: Children and adolescents who sustained a TBI have slightly lower long-term survival time for all-cause mortality, most of which occurs during the first year following injury. There is no clinically meaningful difference in deaths by suicide between the two injury groups.
RESUMEN
PURPOSE: Labor pain can be treated by medical and non-medical analgesia. Smoking during pregnancy has been shown to increase the incidence of several complications and may influence analgesic effectiveness. Previous studies have linked socioeconomic status to the use of epidurals for labor analgesia. We aimed to determine whether smoking and socioeconomic status influence the use of labor analgesia in Finland. METHODS: From January 1, 2004 to December 31, 2018, we collected data from the national Finnish Medical Birth Register on smoking status, labor analgesia, and socioeconomic status during pregnancy. These categorized variables were presented as absolute numbers and percentages. We included data on singleton pregnancies and excluded any data on pregnancies that missed smoking or socioeconomic status. RESULTS: 71,603 women smoked during the first trimester, 42,079 women continued to smoke after the first trimester, and 641,449 were non-smokers. The four most used labor analgesia were nitrous oxide, epidural, other medical analgesia, and non-medical analgesia. The most frequently used analgesia was nitrous oxide, which was used by 60.8% of the group of smokers after the first trimester, 58.8% of smokers during the first trimester, and 54.5% of non-smokers. There were no substantial differences between socioeconomic status classes and labor analgesia used. CONCLUSION: Women who continued smoking after the first trimester used labor analgesia more often than non-smokers. There were no clear differences between socioeconomic status classes and labor analgesia used. These findings highlight the need to reduce maternal smoking during pregnancy, and universal social healthcare systems should promote equality in labor analgesia.

BACKGROUND: The aim of this study was to assess the association between epidural labor analgesia and the mode of delivery for the second twin and to analyze the health outcomes of the second twin. METHODS: In this nationwide, retrospective, register-based cohort study, data from the National Medical Birth Register (MBR) of Finland (2004-2018) were used to analyze the association between epidural analgesia and delivery mode (emergency and urgent cesarean section, and assisted vaginal delivery) and fetal outcomes (neonatal mortality and need for intensive care unit admission) for the second twin. Multivariable logistic regression was used to assess the delivery mode and fetal outcomes of the second twin. RESULTS: A total of 3242 twin pregnancies with epidural analgesia were compared with a control group consisting of 2780 twin pregnancies without epidural analgesia. Epidural analgesia was associated with lower odds for all cesarean delivery (aOR 0.64, 95% CI 0.44 to 0.92) for the second twin and for emergency cesarean delivery (aOR 0.52, 95% CI 0.33 to 0.79) when compared with the odds for the second twin in the control group. Epidural analgesia was associated with lower odds of neonatal mortality for the second twin (aOR 0.61, 95% CI 0.73 to 0.90). CONCLUSION: This study found epidural labor analgesia was associated with a lower rate of emergency cesarean delivery and neonatal mortality for the second twin. These results should be acknowledged by obstetricians and anesthesiologists when planning optimal peripartum management for mothers with twin pregnancies.

OBJECTIVES: The aim of this study was to evaluate the methods used for including or excluding covariates in a multivariable model and to find out how common is the Table 2 Fallacy in studies recently published in high-quality orthopaedic journals. METHODS: A systematic review was conducted in the MEDLINE database. We included all studies that presented the results of a multivariable model in a table and published in seven orthopaedic journals with the highest ranked impact factors in 2019. RESULTS: Table 2 Fallacy was found in 67% (129/193) of the evaluated studies in which a multivariable model was used. Only 16% (31/193) of all studies had included the variables based on causal inference. Furthermore, only three of these studies used causal diagrams to illustrate the causal inference. Altogether, 35% (67/193) of the studies included variables based on statistical methods. CONCLUSIONS: Confounder selection and the interpretation of the results of the multivariable model showed notable challenges in orthopaedic studies recently published in the top orthopaedic journals. Based on the results of our review, it seems that more education in statistics and increased knowledge is required to decrease the occurrence of these statistical issues in orthopaedic research.

BACKGROUND AND AIMS: No previous studies have analyzed the connection between total hip replacement and induced abortion. We evaluated the nationwide induced abortion rates among women with and without total hip replacement. MATERIALS AND METHODS: Data for this cohort study were gathered from national registers from 1987 to 2007. All fertile-aged (15-44 years old) females who had undergone primary total hip replacement in Finland were selected. The total hip replacement patient group comprised 1713 women and the reference group 5148 women. Information on all pregnancies for both groups before and after total hip replacement/index date was gathered from the medical birth register and the register of induced abortion. Logistic regression model was used to analyze the adjusted odds ratio for induced abortion. Adjustment was made for age at induced abortion, parity, previous induced abortions, previous deliveries, and marital status. RESULTS: Women had higher induced abortion proportions after total hip replacement (17.9%) compared with women before total hip replacement (14.1%) and the referents (13.9%), but the differences were not statistically significant. Women in the total hip replacement patient group had significantly more induced abortions after total hip replacement due to maternal health issues (14.7%) compared with the referents (2.7%), p = 0.003. Patients in the total hip replacement group were not more likely to have their pregnancy ending in induced abortion than the women in the reference group (odds ratio 1.32, 95% confidence interval 0.89-1.96, p = 0.17). However, in the adjusted analysis, there was a trend for higher risk for pregnancy to end in induced abortion in the total hip replacement group in relation to the reference group (adjusted odds ratio 1.50 (confidence interval 0.99-2.28, p = 0.05). CONCLUSION: The total hip replacement patient group had higher, but statistically insignificant, induced abortion proportions compared with the reference group before and after the operation. After total hip replacement, the patients were not more likely to have a pregnancy ending in induced abortion. This finding remained statistically insignificant after adjusting with possible confounders.
