Effects of Gender and Comorbidity on Problem Drinking in a Community Sample

We investigated the influence of gender, comorbidity, drinking history, and age on the clinical manifestations of DSM-III alcohol abuse and/or dependence in men and women. The sample was drawn from the National Institute of Mental Health Epidemiologic Catchment Area study, a large-scale, multicenter survey to investigate psychiatric disorders in the community. The results showed that gender and comorbidity had independent effects on problem drinking after drinking history and age had been taken into account. Gender contributed to the age of onset of problem drinking and the rate of its development. Comorbidity, drinking history, and age contributed independently to its severity. The effects of these variables in this community sample paralleled those reported in treatment samples.     

Neurophysiological Correlates of Fatigue in Multiple Sclerosis

Examining fatigue may be beneficial for nurse practitioners to intervene in the care of patients with multiple sclerosis (MS). We measured the relationship of fatigue severity with event-related potentials during electroencephalogram and diffusion basis spectrum imaging/magnetic resonance imaging in 11 participants with relapsing-remitting MS and 5 healthy controls. Data were analyzed to measure brain activity during event-related potentials to responses to cue (correct response) and distractor (incorrect response) using a cognitive performance task. Nurse practitioners caring for patients with MS have an important role in monitoring fatigue severity.     

A New MRI Grading System for Cervical Foraminal Stenosis Based on Axial T2-Weighted Images

ObjectiveThe purpose of this study was to evaluate the reliability of a new magnetic resonance imaging (MRI) grading system for cervical neural foraminal stenosis (NFS).ResultsFor the distinction among the three individual grades at all six neural foramina, the ICC ranged from 0.68 to 0.73, indicating fair to good reproducibility. The percentage agreement ranged from 60.2% to 70.6%, and the kappa values (κ = 0.50-0.58) indicated fair to moderate agreement. The percentages of intraobserver agreement ranged from 85.4% to 93.8% (κ = 0.80-0.92), indicating near perfect agreement.ConclusionThe new MRI grading system shows sufficient interobserver and intraobserver agreement to reliably assess cervical NFS.     

血清chemerin含量与膝骨关节炎严重程度的相关性

目的通过测定不同严重程度的骨关节炎患者血清中chemerin水平,探讨chemerin水平与骨关节炎严重程度的相关性。方法收集临床收治的膝骨关节炎患者血清80例作为研究组,20名正常人血清作为对照组,采用酶联免疫吸附试验法(ELISA)对其血清中的chemerin水平进行检测,膝骨关节炎影像学严重程度评分采用国际公认的Kellgren-Lawrence(K-L)评分系统。结果骨关节炎组血清中chemerin水平显著高于对照组,差异有统计学意义(t=4.983,P<0.01)。骨关节炎组血清chemerin水平与K-L分级有显著相关性(r=0.901,P<0.001)。结论血清chemerin水平在骨关节炎患者中显著升高,且与影像学K-L分级严重程度正相关,血清chemerin水平可作为骨关节炎诊断及判断严重程度的参考指标。     

Chronic obstructive pulmonary disease in heart failure: accurate diagnosis and treatment

Coincidence of COPD and heart failure (HF) is challenging as both diseases interact on multiple levels with each other, and thus impact significantly on diagnosis, disease severity classification, and choice of medical therapy. The current overview aims to educate caregivers involved in the daily management of patients with HF and (possibly) concurrent COPD in how to deal with clinically relevant issues such as interpreting spirometry, the potential role of extensive pulmonary function testing, and finally, the potential beneficial, but also detrimental effects of medication used for HF and COPD on either disease.     

Genetics of asthma susceptibility and severity

This article summarizes major findings in genome-wide studies of asthma susceptibility and severity. Two large meta-analyses identified four chromosomal regions which were consistently associated with development of asthma. Genes that are associated with asthma subphenotypes such as lung function, biomarker levels, and asthma therapeutic responses can provide insight into mechanisms of asthma severity and disease progression. Future genetic studies will incorporate sequencing in comprehensively phenotyped asthmatics to lead to the development of personalized therapy.     

Effects of severity and location of nonsyndromic hypodontia on craniofacial morphology

Objective:To evaluate the effects of severity and location of nonsyndromic hypodontia on craniofacial morphology.Materials and Methods:A total of 154 patients with at least two or more congenitally missing teeth were selected and divided into two groups (group I [mild]: patients with two to five missing teeth; group II [severe]: patients with six or more missing teeth). The patients with hypodontia were divided into three groups according to the location of missing teeth in the dental arches (anterior, posterior, and both anterior and posterior) and location of missing teeth between the jaws (maxilla, mandible, and both maxilla and mandible). Fifty Class I patients without any missing teeth served as the control group. Twenty-one measurements were performed on lateral cephalograms. Intergroup differences for the severity and location of hypodontia were analyzed using analysis of variance (ANOVA) and post-hoc Tukey tests.Results:Significant decreases were found in mandibular plane angles (P < .05), upper and lower incisor measurements (P < .05), anterior (P < .001) and posterior (P < .05) face heights, and ramus height (P < .01), as well as a significant increase in the soft tissue convexity angle (P < .05) among the hypodontia groups and control group. These differences were more excessive in the severe hypodontia group. Upper lip-E plane measurements were significantly longer in the mandible group than in the maxilla group (P < .01).Conclusions:Patients with congenitally missing teeth have different craniofacial morphologies. The severity and location of missing teeth have a significant effect.     

Cold hypersensitivity after hand injuries. A prospective 7-year follow-up

Abstract

We studied changes in cold hypersensitivity from 3 to 7 years following severe hand injuries. Data was collected using postal questionnaires 7 years after injury in 71 patients who had participated in a 3-year follow-up from the time of injury. There was no change in cold sensitivity measured using the McCabe Cold Sensitivity Severity scale (CSS) from 3 to 7 years after injury. However, there was a trend toward decreased severity measured using a five-level scale of self-reported cold hypersensitivity. Compared to the 3-year follow-up, fewer respondents rated their condition as severe and two patients had recovered from their cold hypersensitivity at the 7-year follow-up. Furthermore, 21 (30%) of the respondents stated a decrease in cold hypersensitivity during the last 2 years. Limitations in cold associated activities and the importance of being less limited in leisure activities (NRS 0-10) did not change between the two follow-ups. In conclusion, the CSS-scores did not change from 3 to 7 years after injury. Several patients experienced improvements in cold hypersensitivity, but few recovered completely from the condition.
