Abstract Background: Anterior knee pain (AKP) is a common limitation to children’s participation in social and physical activities. Therefore, to prevent the occurrence and protraction of AKP, it is crucial to identify risk factors. The purpose of this study was to clarify the factors associated with the occurrence and protraction of AKP in children and adolescents. Method: A three-year prospective cohort study was conducted with children and adolescents aged 8–14 in Japan. We recorded the occurrence of AKP, heel buttock distance, straight leg raising angle (SLRA), dorsiflexion angle of the ankle joint, and the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS). Logistic regression analysis was performed to calculate the odds ratio (OR) for each predicted risk factor for the occurrence and protraction of AKP among subjects without AKP at baseline. Results: We recruited 1,254 children and adolescents for the present study, and 1,133 children and adolescents who did not have AKP at baseline were included in the analysis. Six to nine percent of the subjects developed AKP annually. A high HSS Pedi-FABS score significantly predicted AKP occurrence (in 2017, OR 1.07, 95% CI 1.02−1.12, p = 0.003; in 2018, OR 1.05, 95% CI 1.01−1.10, p = 0.025). Of the participants, 32.9% developed chronic AKP during the follow-up period. When 8-year-old was used as a reference age, 13-year-old subjects (right side, OR 2.37, 95% CI, 1.00−5.61, p = 0.05) and 14-year-old subjects (right side, OR 2.57, 95% CI, 1.00−6.60, p = 0.049; left side, OR 6.32; 95% CI 1.33−30.00, p = 0.020) were at a significantly higher risk of AKP protraction. Conclusions: This study showed that a greater physical activity level was a risk factor for the onset of anterior knee pain in childhood. In addition, one-third of the children and adolescents developed chronic knee pain, and elderly adolescents were at a higher risk of protraction.

Abstract Background Every year an estimated 7.9 million babies are born with birth defect. Of these babies, more than 3 million die and 3.2 million have disability. Improving nationwide information on prevalence of birth defect, risk factor and consequence is required for better resource allocation for prevention, management and rehabilitation. In this study, we assess the prevalence of birth defect, associated risk factors and consequences in Nepal. Method This is a prospective cohort study conducted in 12 hospitals of Nepal for 18 months. All the women who delivered in the hospitals during the study period was enrolled. Independent researchers collected data on the social and demographic information using semi-structured questionnaire at the time of discharge and clinical events and birth outcome information from the clinical case note. Data were analyzed on the prevalence and type of birth defect. Logistic regression was done to assess the risk factor and consequences for birth defect. Results Among the total 87,242 livebirths, the prevalence of birth defects was found to be 5.8 per 1000 live births. The commonly occurring birth defects were anencephaly (3.95%), cleft lip (2.77%), cleft lip and palate (6.13%), clubfeet (3.95%), eye abnormalities (3.95%) and meningomyelocele (3.36%). The odds of birth defect was higher among mothers with age < 20 years (adjusted Odds ratio (aOR) 1.64; 95% CI, 1.18–2.28) and disadvantaged ethnicity (aOR 1.78; 95% CI, 1.46–2.18). The odds of birth asphyxia was twice fold higher among babies with birth defect (aOR 1.88; 95% CI, 1.41–2.51) in reference with babies without birth defect. The odds of neonatal infection was twice fold higher among babies with birth defect (aOR 1.82; 95% CI, 1.12–2.96) in reference with babies without birth defect. Babies with birth defect had three-fold risk of pre-discharge mortality (aOR 3.00; 95% CI, 1.93–4.69). Conclusion Maternal age younger than 20 years and advantaged ethnicity were risk factors of birth defects. Babies with birth defect have high risk for birth asphyxia, neonatal infection and pre-discharge mortality at birth. Further evaluation on the care provided to babies who have birth defect is warranted. Funding Swedish Research Council (VR).

Prenatal Risk Factors

Identifying risk factors from pregnancy is essential for preventing child maltreatment. However, few studies have explored prenatal risk factors assessed at pregnancy registration. This study aimed to identify prenatal risk factors for child maltreatment during the first three years of life using population-level survey data from pregnancy notification forms. This prospective cohort study targeted all mothers and their infants enrolled for a 3- to 4-month-old health check between October 2013 and February 2014 in five municipalities in Aichi Prefecture, Japan, and followed them until the child turned 3 years old. Administrative records of registration with Regional Councils for Children Requiring Care (RCCRC), which is suggestive of child maltreatment cases, were linked with survey data from pregnancy notification forms registered at municipalities (n = 893). Exact logistic regression was used for analysis. A total of 11 children (1.2%) were registered with RCCRC by 3 years of age. Unmarried marital status, history of artificial abortion, and smoking during pregnancy were significantly associated with child maltreatment. Prenatal risk scores calculated as the sum of these prenatal risk factors, ranging from 0 to 7, showed high predictive power (area under receiver operating characteristic curve 0.805; 95% confidence interval (CI), 0.660–0.950) at a cut-off score of 2 (sensitivity = 72.7%, specificity = 83.2%). These findings suggest that variables from pregnancy notification forms may be predictors of the risk for child maltreatment by the age of three.

Objectives To analyze the inter-observer reliability of risk for venous thromboembolism (VTE) in a population of adult acutely-ill medical patients. Methods In this prospective cohort study, we collected risk factors and risk classification for VTE using RAM IMPROVE7. Kappa statistics was used to evaluate inter-observer reliability between lead clinicians and trained researchers. We evaluated occurrence of VTE in patients with mismatched classification. Results We included 2,380 patients, median age 70 years (interquartile range [IQR], 58-79), 56.2% female. Adjusted Kappa for VTE risk factors ranged from substantial (0.64, 95% confidence interval [CI], 0.61-0.67) for “immobilization”, to almost perfect (0.98; 95% CI 0.97-0.99) for “thrombophilia”; risk classification was 0.64 (95% CI 0.60-0.67). Divergent risk classification occurred in 434 patients (18.2%) of whom seven (1.6%) developed VTE. Conclusion Despite substantial to almost perfect reliability between observers for risk factors and risk classification, lead clinicians tended to underestimate the risk for VTE.
