There is evidence that staffing characteristics influence quality of care in nursing homes. Federal and state surveyors conduct inspections of homes to assess their compliance with regulatory standards, including requirements related to staffing. Deficiency citations are issued when these standards are not met. This article examines the relationship between operational, facility, and market characteristics and organizational performance measured as staffing-related deficiency citations. Online Survey Certification of Automated Records (OSCAR) data from 2000 through 2007 were used with multinomial logistic regression analyses to identify factors associated with deficiency citations for staffing. Chain members and facilities with poor quality of care were more likely to receive deficiency citations for staffing. Greater bed count and competition between nursing homes were associated with a decreased likelihood of deficiency citations for staffing. Staffing-related deficiencies within nursing homes vary according to various operational, facility, and market characteristics.  相似文献

In addition to the many factors leading to parental alienation syndrome (PAS), including the narcissistic injury felt by the abandoned parent, or the custodial parent's personal difficulty, there are further factors unique to Arab society—including strong influence by the extended family on the child. Although all the components of PAS exist and are well known to the shari'a courts, no parallel concept is found in the Arab legal lexicon. This article presents 1 case of a shari'a court hearing that illustrates this phenomenon. The conclusions indicate that the shari'a court considers this a serious phenomenon and sees coping with the situation as an essential and preliminary condition to the custody hearing.  相似文献

ABSTRACT

The purpose of this study was to examine the level of suicidal ideation and comorbid disorders (major depressive disorder, generalized anxiety disorder) among adolescents and young adults with diagnosed Asperger's syndrome (AS). A cross-sectional study using a self-administrated mail questionnaire and a Web-based questionnaire were used. Two samples were selected for this study. The first sample used snowball sampling, starting with parents of adolescents and young adults with diagnosed AS who participated in a qualitative study conducted in 2002. The second sample consisted of a volunteer sample of parents who visited Web sites for parents and individuals with diagnosed autism spectrum disorder. The sample included 10 adolescents and young adults with diagnosed AS. Fifty percent of the sample had a clinically significant level of suicidal ideation, 20% met criteria for a diagnosis of major depressive disorder, and 30% met criteria for generalized anxiety disorder.  相似文献

Increasing numbers of states are in the process of passing laws requiring all new parents to receive educational materials to prevent shaken baby syndrome (SBS). These laws create powerful opportunities to reach large numbers of families with an important prevention effort. Results from the effort to raise SBS awareness described here indicate that not only is the content of SBS prevention (e.g., consequences of shaking; emotion regulation/coping skills; safety planning) an important consideration; so too is the approach any given prevention program utilizes. By incorporating social work theory on family-centered practice, social workers, home visitors, and other prevention professionals strengthen the likelihood of having a meaningful impact on caregivers' safe strategies for coping with the frustrations of caring for an infant.  相似文献

Abstract

Assessment for chronic fatigue syndrome (CFS) has depended primarily on information obtained through clinical interviews or questionnaire data. The present study used an activity log, which describes patterns of daily behavior, over the course of two days to examine whether differences existed in the pattern, intensity, and qualitative nature of activity among those with CFS, Major Depressive Disorder (MDD) and controls. On average, participants in the CFS group spent significantly more time resting than the MDD group or control group. The CFS group spent nearly 2.5 times more than the MDD group and 4 times more than the control group performing low intensity activity. Findings indicated that people with CFS feel fatigued more of the time, find activity to be fatiguing more of the time, and need more rest during activity than people with MDD or healthy controls.  相似文献

In men with erectile dysfunction, venous leakage is a common condition among non-responders to medical management and is attributed to penile smooth muscle atrophy. Androgens play a role in regulating trabecular smooth muscle growth and function. Further, androgens stimulate differentiation of progenitor cells into smooth muscle cells and inhibit their differentiation into adipocytes. We postulate that androgens exert a direct effect on penile tissue to maintain erectile function, and that androgen deficiency produces metabolic and structural imbalances in the corpus cavernosum, resulting in venous leakage and erectile dysfunction. To date, research efforts on the mechanisms by which androgens regulate penile erectile physiology have mainly focused on investigating the role of the NO/cGMP pathway. However, androgen-dependent mechanisms that regulate tissue remodeling have been poorly defined. Characterization of the molecular and cellular mechanisms by which androgens regulate corpus cavernosum structural and functional integrity would provide significant gains in knowledge and understanding of an important pathogenic process. In this review, we discuss the potential role of androgen in maintaining differentiation of progenitor cells into smooth muscle lineage and inhibition of differentiation into adipocytes. Androgen deficiency promotes differentiation into adipogenic lineage, and accumulation of adipocytes in the corpus cavernosum may contribute to erectile dysfunction.  相似文献

Testosterone therapy has been used for more than 60 years in the treatment of male hypogonadism. The classical forms of hypogonadism are comprised of primary testicular failure or insufficient testicular stimulation due to the lack of pituitary gonadotropins. Typical causes of primary hypogonadism are Klinefelter's syndrome, anorchia or acquired disturbances of testicular function. Secondary hypogonadism is characterized by insufficient production of pituitary gonadotropins, due either to pituitary failure or defects at the hypothalamic level. It is unequivocally accepted in clinical practice that any male with inadequately low testosterone production for his age will require androgen therapy. In addition to the classical forms of hypogonadism, the past decade of research has clearly demonstrated that, with increasing age, many men will suffer from decreasing testosterone production. About 15-25% of men over the age of 50 years will experience serum testosterone levels well below the threshold considered normal for men between 20 and 40 years of age. Studies substituting testosterone in elderly men with low serum testosterone have shown that men with clinical symptoms identical to the symptomatology of classical hypogonadism will benefit most from such therapy. Therefore, it is the general consensus to treat men with age-related hypogonadism only when clinical symptoms are present that can be potentially corrected by testosterone administration. Until recently, intramuscular injections of esters, such as testosterone enanthate, have been the mainstay of testosterone therapy. The introduction of testosterone patches has not challenged this approach, since many users of patches suffer from moderate to severe skin reactions. Some oral testosterone formulations have proven to be problematic, as absorption can be variable, bioavailability is frequently poor, due to the first-pass effect of the liver, and frequent administration is often required<citeref rid="b1"><emph>1</emph></citeref>. Oral testosterone undecanoate avoids, at least partially, the first-pass effect of the liver. However, plasma testosterone levels generally undergo large fluctuations<citeref rid="b2"><emph>2</emph></citeref>. The large fluctuations in serum testosterone levels caused by conventional intramuscular injections result in unsatisfactory shifts in mood and sexual function in some men, which, combined with the frequency of injections, make the intramuscular mode of delivery far from ideal. Recently, a hydroalcoholic gel containing 1% testosterone has proven to be as efficient as a testosterone patch, but with fewer side-effects and a higher grade of patient satisfaction<citeref rid="b3"><emph>3</emph></citeref>-<citeref rid="b4"></citeref><citeref rid="b5"><emph>5</emph></citeref>. Doses of 50-100 mg gel applied once daily on the skin deliver sufficient amounts of testosterone to restore normal hormonal values and correct the signs and symptoms of hypogonadism. The gel has been shown to be effective and successful in patients in the United States, who have benefited from its availability for almost 3 years. In the near future, intramuscular injections of testosterone undecanoate will become commercially available. Such injections have a very favorable pharmacokinetic profile, with one injection every 3 months maintaining serum testosterone well within the normal range. In phase III studies, intramuscular testosterone undecanoate proved to be as efficient as testosterone enanthate, with only one-quarter of the number of injections required and more stable serum testosterone levels. Thus, the new application modes - hydroalcoholic gel (for example, Testogel®, Schering AG, Germany) and intramuscular testosterone undecanoate (Nebido®, Schering AG, Germany) - appear to be the methods of choice in the near future, one being very suitable for hormone therapy in elderly men, the other for long-term substitution in classical forms of hypogonadism.  相似文献

Objective. We examined age associated variation in salivary testosterone values among Japanese males as well as anthropometric measurements.

Methods. Salivary samples were collected in pretreated sodium azide treated tubes. The first series: 15–79-year-old males (n = 99); two morning and two evening samples were collected at home for two days. The second series: 90-year-old males (n = 29); one morning sample was collected. Testosterone values were determined using an iodine125-based radioimmunoassay kit modified for saliva.

Results. Results show 1) a significant decrease in salivary testosterone values from 20s to 40s and older, 2) no significant decline after 40 through 90 years old, 3) no significant age-related differences in the degree of intraindividual diurnal fluctuation across age groups of 40–70s, and 4) higher BMI is associated with the lower salivary testosterone among 40–70s.

Conclusions. These results suggest that neither a constant decrease of salivary testosterone values or markedly reduced intraindividual fluctations are universal aspects of aging. Older males may maintain relatively high testosterone levels compared to younger men and a relatively ‘robust’ neuroendocrinological system.  相似文献

The study of the health status of the aging male takes presently a more integrative approach and it appears that ailments typical of male aging, such as lower urinary tract symptoms (LUTS), (visceral) obesity, metabolic syndrome and erectile failure are significantly interrelated. A common denominator of the above ailments is lower-than-normal testosterone levels occurring in a significant proportion of elderly men. This review addresses the potential connections between LUTS and late-onset hypogonadism. In animal studies there appear to be androgen and estrogen receptors in the urothelium and smooth muscle cells of the urethra and bladder of the rat and rabbit, as well as in the neurons in the autonomic ganglia of the prostatic plexus of the male rat. Upon castration electrically evoked relaxations of the smooth muscle of the prostatic urethra were decreased. There is a Rho-kinase activation/endothelin pathway; possibly involved in the increased smooth muscle activity found in both LUTS/benign prostate hyperplasia. Nitric oxide (NO) appears to have a smooth muscle relaxing effect in the urogenital organs. Studies in humans have convincingly shown that phosphodiestererase inhibitors have a beneficial effect on LUTS. More intervention studies should be undertaken to test the clinical validity of the theoretically plausible interrelationship between LUTS and late-onset hypogonadism.  相似文献

Recent work shows a high prevalence of low testosterone and inappropriately low luteinizing hormone (LH) and follicle stimulating hormone (FSH) concentrations in type 2 diabetes. This syndrome of hypogonadotrophic hypogonadism (HH) is associated with obesity in patients with type 2 diabetes. However, the duration of diabetes or HbA1c are not related to HH. Furthermore, recent data show that HH is not associated with type 1 diabetes. C-reactive protein concentrations have been shown to be elevated in patients with HH and are inversely related to plasma testosterone concentrations. This inverse relationship between plasma free testosterone and C- reactive protein concentrations in patients with type 2 diabetes suggests that inflammation may play an important role in the pathogenesis of this syndrome. This is of interest since inflammatory mechanisms may have a cardinal role in the pathogenesis of insulin resistance. It is also relevant that in the mouse, deletion of the insulin receptor in neurons leads to HH in addition to a state of systemic insulin resistance. It has also been shown that insulin facilitates the secretion of gonadotrophin releasing hormone (GnRH) from neuronal cell cultures. Thus, HH may be the result of insulin resistance at the level of the GnRH secreting neuron. Low testosterone concentrations are also related to an increase in total and regional adiposity. This review discusses these issues and attempts to make the syndrome relevant as a clinical entity. Clinical trials are required to determine whether testosterone replacement alleviates insulin resistance and inflammation. In addition, low testosterone levels are associated with an increase in cardiovascular events. Testosterone therapy may therefore, reduce cardiovascular risk. This important aspect requires further investigation.  相似文献
