Social Factors Related to the Utilization of Health Care Among Prison Inmates

This study examines the demographic and social factors related to health care utilization in prisons using the 2004 Survey of Inmates in State Correctional Facilities. The findings show that education and employment, strong predictors of health care in the community, are not associated with health care in prisons. Although female inmates have a higher disease burden than male inmates, there are no sex differences in health care usage. The factors associated with health care, however, vary for women and men. Notably, Black men are significantly more likely to utilize health care compared to White and Latino men. The findings suggest that, given the constitutionally mandated health care for inmates, prisons can potentially minimize racial disparities in care and that prisons, in general, are an important context for health care delivery in the United States.
Evidence of human papillomavirus infection, enhanced phosphorylation of retinoblastoma protein, and decreased apoptosis in sarcomatoid squamous cell carcinoma of uterine cervix

Sarcomatoid squamous cell carcinoma (SSCC) of the uterine cervix, characterized by biphasic components of sarcomatoid and squamous neoplastic cells, is a rare entity with uncertain pathogenesis. To date, less than 20 cases have been mentioned. Although the rarity of this diagnosis makes it difficult to draw firm conclusions from limited data, it does seem that SSCC is an aggressive tumor. In this study, we present a 31-year-old patient with abnormal vaginal bleeding. The diagnosis of SSCC was confirmed through pathologic examinations from hysterectomy specimen. Its epithelial origin was demonstrated by immunohistochemical studies. The expression of p53, HER2/neu, and c-kit was not enhanced in this tumor. Importantly, it was human papillomavirus type 16, positive by polymerase chain reaction and in situ hybridization studies. Enhanced immunostaining for phospho-retinoblastoma protein and decreased apoptosis compared with the squamous cell carcinoma counterpart were observed. This report characterizes the first description of molecular features in SSCC that may account for its aggressive behavior.
A Field Trial to Assess the Effect of Vaccination against Feline Herpesvirus, Feline Calicivirus and Feline Panleucopenia Virus in 6-Week-Old Kittens

A trivalent (feline panleucopenia, feline herpesvirus, feline calicivirus), modified live, commercially available cat vaccine was used at either 6, 9 and 12 weeks of age (early schedule) or 9 and 12 weeks of age (conventional schedule), and the serological response to vaccination was assessed. The level of maternally derived antibody present at 6 weeks of age was also established. The use of early vaccination at 6 weeks of age induced an antibody response to each virus by 9 weeks of age in a significant proportion of kittens compared with unvaccinated littermates. There was no difference between the conventionally and early-vaccinated groups in terms of antibody response to any antigen by 12 and 15 weeks of age.
Transthoracic needle biopsy of small pulmonary nodules.

PURPOSE To evaluate the diagnostic accuracy, complications, and usefulness of transthoracic needle biopsy of small pulmonary nodules. MATERIALS AND METHODS Between January 1993 and January 1995, 302 patients underwent transthoracic needle biopsy of pulmonary lesions. Sixty-four lesions (in 62 patients) represented small nodules, defined as lesions of 15 mm or less maximum diameter. A total of 75 biopsies were performed in the 64 lesions. Approximately 90% of the biopsies were performed with computed tomographic guidance. RESULTS There were 21 benign lesions and 43 cancers (36 primary, seven metastatic). Transthoracic needle biopsy findings were positive for cancer in 40 cases. In all three false-negative lesions, only one biopsy was performed. There were 21 true-negative results and no false-positive results. Positive and negative predictive values were 100% and 88%, respectively. Pneumothorax occurred in 20 (27%) of 75 biopsies, but chest tube placement was necessary in only three cases (4%). Surgery or thoracoscopy was avoided in 31 patients: 17 of 20 patients with benign disease, seven patients with metastatic disease, and seven patients with inoperable lung cancer. CONCLUSION Transthoracic needle biopsy of small pulmonary nodules can produce diagnostic yields comparable with published results of transthoracic needle biopsy of larger lesions.
Effect of a 5‐week static stretching program on hardness of the gastrocnemius muscle

This study investigated the effects of a static stretching (SS) program on muscle hardnesses of the gastrocnemius medialis (MG) and gastrocnemius lateralis (LG). Nineteen young men participated in this study. Either the right or left leg was randomly selected to conduct three bouts of 2‐min SS of the plantar flexors 6 days a week for 5 weeks in each subject (the SS group), and the other leg was assigned to a control group. Before (pretest) and after (posttest) conducting the SS program, MG and LG hardnesses were measured using shear wave ultrasound elastography. The SS program was found to decrease muscle hardnesses, but not to change the ratio of MG hardness to LG hardness. There were no significant differences between the relative changes in the MG and LG hardnesses from pretest to posttest in both the SS and control groups. Significant correlations between the muscle hardness ratios at pretest and posttest were found in both groups. The results of this study suggest that the current SS program is useful for improving muscle condition in the plantar flexors, and that its long‐term effects on the MG and LG hardnesses are of the same degree.
Visual Activation in Functional Magnetic Resonance Imaging at Very High Field (4 Tesla)

Objectives Functional magnetic resonance imaging (fMRI) at very high field strengths provides functional brain mapping with the enhanced signal to noise ratio and the larger blood oxygenation level–dependent (BOLD) effect. We report activated areas in the standard space detected by fMRI at 4 Tesla (T) during simple visual stimulation. Materials and Methods Twelve healthy young subjects were scanned using a 4 T scanner during binocular flashing visual stimulation. Functional images were realigned to the first scan and then spatially normalized. Individual and group data analyses were performed to identify areas of visual activation. Results Activation of the bilateral primary visual cortex (V1/V2) was observed along the entire calcarine fissure in all subjects. The activated area extended to the extrastriate cortex in all subjects. Activation of the bilateral lateral geniculate nucleus (LGN) was detected in all subjects. The group data showed activation of the bilateral primary visual cortex and the bilateral lateral geniculate nucleus. Conclusions Robust activation of the vision-related areas was successfully obtained in all subjects using a 4 T magnetic resonance scanner. These results suggest that fMRI at very high field strengths may be effective in showing visual system physiology, and that it can be a promising method to assess visual function of human subjects.
Agoraphobia: The Long-Term Follow-up of Behavioural Treatment

Summary Sixty-six agoraphobic patients were followed up five to nine years after their treatment in three clinical trials of behaviour therapy. The main outcome measures used in the original trials were repeated by an assessor who interviewed the patients. Ninety-five per cent of patients were interviewed and partial information was obtained on a further two patients. The measures taken at follow-up were compared with those obtained prior to treatment and six months after treatment ended. On most measures of agoraphobia the patients were much better at follow-up than they had been before treatment. The assessor's ratings suggested that there had been little change in the patients' agoraphobia since six months after treatment. Some of the patients' self-ratings showed evidence of a slight improvement over this period. No evidence of symptom substitution was found.
Paradox of Bcl-2 (and p53): why may apoptosis-regulating proteins be irrelevant to cell death?

Although the Bcl-2 family members and p53 are involved in the regulation of apoptosis, the status of apoptotic machinery (eg caspases) plays a major role in determining the mode and timing of cell death. If the apoptotic machinery is lost, inhibited, or intrinsically inactivated, the "death stars", Bcl-2 and p53, may become irrelevant to cell death. In this light, high levels of Bcl-2 may indicate that downstream apoptotic pathways are still functional. This explains why Bcl-2 overexpression can be a marker of chemosensitivity and favorable prognosis in certain cancers and why retention of wild-type p53 may manifest inactivation of caspases in aggressive cancers.
Stromal Cells Provide the Matrix for Migration of Early Lymphoid Progenitors Through the Thymic Cortex1

During steady state lymphopoiesis in the postnatal thymus, migration of precursors outward from the deep cortex toward the capsule is required for normal differentiation. Such migration requires, at a minimum, expression of adhesive receptors on the migrating lymphoid cells, as well as a stable matrix of their ligands persisting throughout the region of migration. In this study, we address the nature of this adhesive matrix. Although some precursor stages bound efficiently to extracellular matrix ligands, a specific requirement for the cell surface ligand VCAM-1 was also found. In situ analysis revealed that early precursors are found in intimate contact with a matrix formed by stromal cells in the cortex, a proportion of which expresses VCAM-1. In vivo administration of an anti-VCAM-1 Ab resulted in decreased thymic size and altered distribution of early precursors within the cortex. These results indicate that precursors migrating outward through the cortex may use a cellular, rather than extracellular, matrix for adhesion, and suggest that the VCAM-1+ subset of cortical stroma may play a crucial role in supporting the migration of early precursors in the steady state thymus.
The utility of apolipoprotein E genotyping in the diagnosis of Alzheimer disease in a community-based case series.

CONTEXT A recent collaborative study found that apolipoprotein E (APOE) genotype, in conjunction with the clinical diagnosis of Alzheimer disease (AD), was useful in improving diagnostic specificity (correctly not diagnosing AD) relative to the clinical diagnosis alone. Since these samples are particularly enriched with patients with AD and the APOE epsilon4 allele, results may not be generalizable to patients seen in the general medical community. OBJECTIVE To evaluate the diagnostic utility of the APOE genotype in diagnosing AD in a community-based case series from the largest health maintenance organization in an urban area. DESIGN We examined the effect of including APOE genotype on the diagnosis of AD in a community-based case series of patients presenting with memory complaints. PATIENTS Clinical and neuropathologic diagnoses and APOE genotype were obtained from 132 patients who underwent evaluation for dementia and subsequent autopsy. MAIN OUTCOME MEASURES Sensitivity, specificity, and positive and negative predictive values given various combinations of clinical diagnoses and the presence of an APOE epsilon4 allele. RESULTS Of the 132 patients, 94 had neuropathologically confirmed AD, yielding a prevalence of 71%. The clinical diagnosis alone yielded a sensitivity of 84%, an estimated specificity of 50%, and positive and negative predictive values of 81% and 56%, respectively. The presence of an epsilon4 allele alone was associated with an estimated sensitivity of 59%, specificity of 71%, and positive and negative predictive values of 83% and 41%, respectively. Using the presence of clinical AD and an epsilon4 allele decreased the sensitivity to 49% and increased the specificity to 84%. The positive and negative predictive values were 88% and 40%, respectively. Alternatively, the clinical diagnosis of AD or the presence of an epsilon4 allele in individuals not meeting clinical criteria for AD increases the estimated sensitivity to 94% but decreases the specificity to 37%. The positive and negative predictive values were 79% and 70%, respectively. The changes in the sensitivity and specificity for the combined tests relative to clinical diagnosis alone offset each other. For lower prevalence communities, the positive predictive value will be much lower than those observed herein. CONCLUSIONS Our findings do not support the use of APOE genotyping alone in the diagnosis of AD in the general medical community. Although the presence of an epsilon4 allele in older persons with clinical AD increased the probability of having AD and the absence of an epsilon4 allele in this group decreased the probability of having AD, the association is not strong enough in the differential diagnosis of non-Alzheimer dementia and AD.
Opioid receptors and cardioprotection – ‘opioidergic conditioning’ of the heart

Ischaemic heart disease (IHD) remains a major cause of morbidity/mortality globally, firmly established in Westernized or ‘developed’ countries and rising in prevalence in developing nations. Thus, cardioprotective therapies to limit myocardial damage with associated ischaemia–reperfusion (I–R), during infarction or surgical ischaemia, is a very important, although still elusive, clinical goal. The opioid receptor system, encompassing the δ (vas deferens), κ (ketocyclazocine) and μ (morphine) opioid receptors and their endogenous opioid ligands (endorphins, dynorphins, enkephalins), appears as a logical candidate for such exploitation. This regulatory system may orchestrate organism and organ responses to stress, induces mammalian hibernation and associated metabolic protection, triggers powerful adaptive stress resistance in response to ischaemia/hypoxia (preconditioning), and mediates cardiac benefit stemming from physical activity. In addition to direct myocardial actions, central opioid receptor signalling may also enhance the ability of the heart to withstand I–R injury. The δ‐ and κ‐opioid receptors are strongly implicated in cardioprotection across models and species (including anti‐infarct and anti‐arrhythmic actions), with mixed evidence for μ opioid receptor‐dependent protection in animal and human tissues. A small number of clinical trials have provided evidence of cardiac benefit from morphine or remifentanil in cardiopulmonary bypass or coronary angioplasty patients, although further trials of subtype‐specific opioid receptor agonists are needed. The precise roles and utility of this GPCR family in healthy and diseased human myocardium, and in mediating central and peripheral survival responses, warrant further investigation, as do the putative negative influences of ageing, IHD co‐morbidities, and relevant drugs on opioid receptor signalling and protective responses.
Quantitative Ultrasound Imaging of Healthy and Reconstructed Cleft Lip: A Feasibility Study

Objective: To investigate the feasibility of echographic imaging of healthy and reconstructed cleft lip and to estimate tissue dimensions and normalized echo level. Methods: Echographic images of the upper lip were made on three healthy subjects and two patients using a linear array transducer (7 to 11 MHz bandwidth) and a noncontact gel coupling. Tissue dimensions were measured using calipers. Echo levels were calibrated and were corrected for beam characteristics, gel path, and tissue attenuation using a tissue-mimicking phantom. Results: At the central position of the philtrum, mean thickness (SD) of lip loose connective tissue layer, orbicularis oris muscle, and dense connective layer was 4.0 (0.1) mm, 2.3 (0.7) mm, and 2.2 (0.7) mm, respectively, in healthy lip at rest; and 4.1 (0.9) mm, 3.8 (1.7) mm, and 2.6 (0.6) mm, respectively, in contracted lip. Mean (SD) echo level of muscle and dense connective tissue layer with respect to echo level of lip loose connective tissue layer was −19.3 (0.6) dB and −10.7 (4.0) dB, respectively, in relaxed condition and −20.7 (1.5) dB and −7.7 (2.3) dB, respectively, in contracted state. Color mode echo images were calculated, showing lip tissues in separate colors and highlighting details like discontinuity of the orbicularis oris muscle and presence of scar tissue. Conclusions: Quantitative assessment of thickness and echo level of various lip tissues is feasible after proper echographic equipment calibration. Diagnostic potentials of this method for noninvasive evaluation of cleft lip reconstruction outcome are promising.
Comparison of Clinical Outcomes and Radiographic Measurements in 4 Different Treatment Modalities for Osteoporotic Compression Fractures: Retrospective Analysis

Study Design: We conducted a retrospective analysis of a prospectively collected database in a tertiary hospital over 10 years. Objective: Treatment for vertebral compression fractures remains an area of controversy with respect to timing and type of surgical management. We analyzed the clinical outcomes and radiographic measurements of 4 different modalities of treatment for these fractures. Summary of Background Data: From 2001 to 2011, we analyzed a total of 363 patients after failure of 30 days of conservative management. These patients were then further managed either conservatively or with vertebroplasty, balloon kyphoplasty, or sky bone expander. Outcomes were assessed by using self-report measures: Visual Analog Score; functional measures: Oswestry Disability Index and Short-Form 36; and physiological measures: preoperative and postoperative radiographs. Methods: The outcome measures were assessed for 6 months for those treated conservatively and up till 2 years for those treated surgically. Radiographic measurements of the spine were correlated with the clinical outcomes. Results: A total of 62 patients (12.1%) were treated conservatively, 148 (40.8%) with vertebroplasty, 97 (26.7%) with balloon kyphoplasty, and 56 (15.4%) with sky bone expander. We found significant improvements in Visual Analog Score, Oswestry Disability Index, and Short-Form-36 scores for all groups after 1-month follow-up (P<0.05), with the surgical groups demonstrating a greater improvement in pain scores after the first postoperative day (P<0.0001) when compared with the conservative group. The improvements in outcomes in those treated surgically were sustained for up to 2 years with no significant difference (P>0.05) among the surgical groups. We also found significant improvement (P<0.005) in anterior vertebral and kyphotic wedge angle after surgical intervention. Conclusions: We have shown that early surgical intervention allows for quicker pain relief compared with conservative treatment, with similar improvements in anterior vertebral height and kyphotic wedge angle between all 3 groups of surgical management.
Lithium-Induced Parathyroid Dysfunction: A Case Report and Review of the Literature

OBJECTIVE: Twenty-six cases of lithium-induced hyperparathyroidism have been reported in the literature. This article describes an additional case that illustrates current management recommendations. DESIGN: Case report. Clinical presentation and proposed mechanisms of the suspected drug-induced effect are discussed. CONCLUSIONS: Serum calcium concentrations should be determined before and periodically during long-term lithium carbonate therapy. Discontinuation of therapy in patients who develop lithium-induced parathyroid dysfunction generally corrects calcium and parathyroid hormone concentrations. Surgery is indicated in patients with complications of hyperparathyroidism.
The safety and efficacy of laparoscopic live donor nephrectomy: a systematic review.

BACKGROUND The aim of this systematic review was to compare the safety and efficacy of laparoscopic live donor nephrectomy with the "gold" standard of open live donor nephrectomy. METHODS SEARCH STRATEGY Three search strategies were devised to enable literature retrieval from the Medline, Current Contents, Embase, and Cochrane Library databases up until, and including, February 2000. STUDY SELECTION Inclusion of a report was determined on the basis of a predetermined protocol, independent assessment by two reviewers, and a final consensus decision. English language reports were selected and acceptable study designs included randomized-controlled trials, controlled clinical trials, case series, or case reports. Each report was required to provide information on at least one of several safety and efficacy outcomes as detailed in the protocol. DATA COLLECTION AND ANALYSIS Twenty-five reports met the inclusion criteria. They were tabulated and critically appraised in terms of the methodology and design, sample size, outcomes, and the possible influence of bias, confounding, and chance. RESULTS High level evidence comparing the safety and efficacy of laparoscopic live donor nephrectomy with open donor nephrectomy was not available at the time of this review. Limited low level evidence suggested that the laparoscopic approach might be advantageous regarding the donor's hospital stay, convalescence, pain, and resumption of employment. CONCLUSIONS The ASERNIP-S Review Group concluded that the evidence-base for laparoscopic live donor nephrectomy was inadequate to make a safety and efficacy recommendation. Clinical and research recommendations were developed regarding the introduction and current practice of this procedure in Australia.
Usefulness of the CRAFFT to Diagnose Alcohol or Cannabis Use Disorders in a Sample of Emerging Adults with Past-Month Alcohol or Cannabis Use

ABSTRACT Background: Emerging adults between the ages of 18 and 25 have the highest rates of illicit drug use and heavy alcohol use. The purpose of this study was to determine the performance of the Relax, Alone, Forget, Family/Friends, Trouble (CRAFFT) screening to identify alcohol and cannabis use disorders using Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria in a sample of emerging adults who use alcohol or cannabis or both. Methods: Study participants were recruited as part of a larger intervention study of health behaviors among emerging adults between the ages of 18 and 25 reporting alcohol and/or cannabis use. As part of baseline data collection, responses to the CRAFFT (score range: 0–6) and the Structured Clinical Interview for DSM-IV (SCID) were recorded. Additional questions about craving permitted approximation with DSM-5 diagnoses of alcohol and cannabis use disorders. Results: Participants (N = 382) averaged 21 (±2.1) years of age, 47% were male, 65% were non-Latino Caucasian, and using the SCID 42% met criteria for an alcohol use disorder and 45% met criteria for cannabis use disorder. When evaluating for any alcohol use disorder alone, using a cutoff score of 4, the sensitivity was 81.4% but the specificity was only 45.3%. At a cutoff score of 4, sensitivity for identifying any cannabis use disorder alone was 83.7% and specificity was 48.6%. Conclusions: In emerging adults who report using alcohol or cannabis, the CRAFFT had low specificity for predicting alcohol or cannabis use disorder, despite using higher cut scores than previously published. The CRAFFT's utility in determining clinical substance use disorders in this population may be limited.
