Race–Gender Differences in the Impact of History of Heavy Drinking on Current Alcohol Consumption during the Transition to Adulthood
American youth transitioning to adulthood consume more alcohol than in any other period of the life course. This high level of consumption can result in serious consequences, including lost productivity, death and disability, sexual assault, and addiction. Nevertheless, relatively little is known, especially by race and gender, about how prior history of heavy drinking (e.g., in late adolescence) impacts drinking in young adulthood. Utilizing data from the National Longitudinal Survey of Youth (1994-2004) for African Americans, Latinos, and Whites (N = 2,300), we found that Whites and Latinos drink more than African Americans, and men report drinking more than women. However, accounting for a history of heavy drinking introduces considerable variation in current drinking patterns by race–gender status. A history of heavy drinking more than doubles the number of drinks consumed by African American women, putting their drinking levels on par with African American men and White women and raising their level of drinking above Latinas. Further, African American women\u27s probability of heavy drinking becomes indistinguishable from that of African American men and White women, once accounting for a prior history of binge drinking. For Latinas with a history of heavy drinking, the probability of being a current binge drinker is equal to Latinos and White men and higher than African Americans and White women
Bone Fractures With and Without Sickle Cell Disease in the Pediatric Population
Background: Individuals with sickle cell disease are restricted from certain physical activities due to the increased risk of complications including fractures secondary to osteopenia. However the exact incidence and outcomes of fractures amongst these patients is unknown.
Objectives: (1) describe the incidence, epidemiology, and outcomes of fractures in patients with SCD. (2) to compare fracture patterns and outcomes in patients with and without SCD.
Methods: This is a retrospective, cohort study of patients aged 0-25 years old with HbSS, HbSC, or HbS-β-thalassemia with a fracture evaluated at a pediatric emergency department from April 2009-April 2022. Eligible patients were identified using a combination of ICD billing codes and a preexisting hematology clinic database. Patients were age/gender matched with non-SCD patients with fractures. Data on demographics, number and types of fractures and outcomes were collected.
Results: 753 patients with SCD were identified during the study period. SCD patients with fractures were more likely to have multiple comorbidities, lower mean vitamin D levels and were less likely to be on vitamin D supplementation compared to those without fractures. The most common etiology was fall and carpal bones were most commonly fractured. Non-SCD patients with fractures were more likely to be obese and require surgical repair compared to their SCD peers.
Conclusions: Fracture incidence among SCD patients is low. Male gender, multiple comorbidities, and lack of vitamin D supplementation are associated with increased risk of fracture. SCD patients with a fracture were less likely to require surgical treatment compared to their non-SCD counterparts
Infraspinatus scapular retraction test: a reliable and practical method to assess infraspinatus strength in overhead athletes with scapular dyskinesis
Background Alteration of normal scapulohumeral rhythm due to the fatigue of scapular-stabilizing muscles induces decrease of rotator cuff strength. In this study we analyzed the interobserver and intraobserver realibility of the infraspinatus strength test (IST) and infraspinatus scapular retraction test (ISRT) in 29 overhead athletes with scapular dykinesis, before and after 6 months of scapular musculature rehabilitation. Materials and methods Subjects with magnetic resonance imaging (MRI) findings of labral injuries (2 cases, 5%) and cuff tears (4 cases, 11%) were excluded. Scapular dyskinesis patterns were evaluated according to Kibler et al. (J Shoulder Elbow Surg 11:550-556, 2002). We found a type I dyskinesis in 24 cases (83%) and a type II in 5 cases (17%). Patients were tested by using IST and ISRT and the maximum infraspinatus strength (kg) was registered by a handheld dynamometer. Changes in shoulder IR were measured by using a standard goniometry. Rehabilitation continued for 6 months and was focused on the restoration of scapular muscular control and balance. We used a paired Student t test for the significance of the force values (alpha = 0.01). Intraclass correlation coefficient (ICC) and standard error (SE) were applied to determine the realibility of repeated values collected within testers and between testers. Results Values of ICC close to 1 at baseline and at 6 months indicated a higher interexaminer and intraexaminer realibility. IST force values registered a significant increase at 6 months for both examiners (P<0.01). The mean difference between IST and ISRT values were not significant at 6 months (P>0.01). The increase of glenohumeral internal rotation was significant at 6 months (P<0.01). Conclusion The good realibility and the easy reproducibility make the ISRT an excellent test to assess patients with infraspinatus weakness due to scapular dyskinesis and address them toward an appropriate program of rehabilitation aimed to restore scapular musculature balance and control. \ua9 The Author(s) 2010
FBXW7 and USP7 regulate CCDC6 turnover during the cell cycle and affect cancer drugs susceptibility in NSCLC
CCDC6 gene product is a pro-apoptotic protein substrate of ATM, whose loss or inactivation enhances tumour progression. In primary tumours, the impaired function of CCDC6 protein has been ascribed to CCDC6 rearrangements and to somatic mutations in several neoplasia. Recently, low levels of CCDC6 protein, in NSCLC, have been correlated with tumor prognosis. However, the mechanisms responsible for the variable levels of CCDC6 in primary tumors have not been described yet. We show that CCDC6 turnover is regulated in a cell cycle dependent manner. CCDC6 undergoes a cyclic variation in the phosphorylated status and in protein levels that peak at G2 and decrease in mitosis. The reduced stability of CCDC6 in the M phase is dependent on mitotic kinases and on degron motifs that are present in CCDC6 and direct the recruitment of CCDC6 to the FBXW7 E3 Ubl. The de-ubiquitinase enzyme USP7 appears responsible of the fine tuning of the CCDC6 stability, affecting cells behaviour and drug response. Thus, we propose that the amount of CCDC6 protein in primary tumors, as reported in lung, may depend on the impairment of the CCDC6 turnover due to altered protein-protein interaction and post-translational modifications and may be critical in optimizing personalized therapy
Can clinical assessment differentiate partial thickness rotator cuff tears from full thickness rotator cuff tears? A secondary analysis
Quantitative risk assessment of skin sensitising pesticides: Clinical and toxicological considerations.
Like many other consumer and occupational products, pesticide formulations may contain active ingredients or co-formulants which have the potential to cause skin sensitisation. Currently, there is little evidence they do, but that could just reflect lack of clinical investigation. Consequently, it is necessary to carry out a safety evaluation process, quantifying risks so that they can be properly managed. A workshop on this topic in 2022 discussed how best to undertake quantitative risk assessment (QRA) for pesticide products, including learning from the experience of industries, notably cosmetics, that already undertake such a process routinely. It also addressed ways to remedy the matter of clinical investigation, even if only to demonstrate the absence of a problem. Workshop participants concluded that QRA for skin sensitisers in pesticide formulations was possible, but required careful justification of any safety factors applied, as well as improvements to the estimation of skin exposure. The need for regulations to stay abreast of the science was also noted. Ultimately, the success of any risk assessment/management for skin sensitisers must be judged by the clinical picture. Accordingly, the workshop participants encouraged the development of more active skin health monitoring amongst groups most exposed to the products
Oral Literature in the Digital Age
Thanks to ever-greater digital connectivity, interest in oral traditions has grown beyond that of researcher and research subject to include a widening pool of global users. When new publics consume, manipulate and connect with field recordings and digital cultural archives, their involvement raises important practical and ethical questions. This volume explores the political repercussions of studying marginalised languages; the role of online tools in ensuring responsible access to sensitive cultural materials; and ways of ensuring that when digital documents are created, they are not fossilised as a consequence of being archived. Fieldwork reports by linguists and anthropologists in three continents provide concrete examples of overcoming barriers-ethical, practical and conceptual-in digital documentation projects. Oral literature In The Digital Age is an essential guide and handbook for ethnographers, field linguists, community activists, curators, archivists, librarians, and all who connect with indigenous communities in order to document and preserve oral traditions. This book is part of the World Oral Literature Series, developed in conjunction with the World Oral Literature Protect
