[Current understanding of the role of age-related hypogonadism in the development of cardiovascular diseases].

The literature review presents novel data on the prevalence of age-related hypogonadism and its relationship with aging, its impact on the circulatory system and cardiovascular diseases. This review summarizes the methods for diagnosing age-related hypogonadism, its association with traditional cardiovascular risk factors such as dyslipidemia, insulin resistance and diabetes mellitus, obesity, arterial hypertension. The mechanisms of the possible direct effect of testosterone on endothelium and vascular tone, the role of hormone replacement therapy as a way of preventing cardiovascular diseases are discussed.

Residential transience among US adolescents: association with depression and mental health treatment.

AIMS: Residential instability, including transience (i.e. unusually frequent mobility), is associated with higher risk for emotional and behavioural problems in children and young adults. However, most studies have not compared the effect of recent v. more distal moves on mental health or on mental health treatment. This study examined associations between recent (past year) and distal (past 2-4 years) residential transience and past year major depressive episode (MDE) and mental health treatment in a nationally representative sample of US adolescents aged 12-17. METHODS: Data are from the 2010-2014 National Surveys on Drug Use and Health (n = ~107 300 adolescents). T-tests were used to examine the prevalence of MDE by number of moves in the past 5 years among a nationally representative sample of adolescents. Additionally, multivariable logistic regression models were used to evaluate the adjusted association between recent (⩾2 moves in the past year) and distal (⩾4 moves in the past 5 years, but no recent transience) and (1) past year MDE and (2) past year mental health treatment among adolescents with MDE. RESULTS: MDE prevalence increased linearly with number of moves in the past 5 years (p < 0.001). The adjusted odds of MDE were greater among youths with distal transience (adjusted odds ratio (AOR) = 1.25, 95% confidence interval (CI) = 1.09-1.44) and among those with proximal transience (AOR = 1.31, 95% CI = 1.17-1.46), compared with those without transience in the past 5 years. The MDE prevalence did not differ between those with distal and proximal transience (p = 0.163). In youths with past year MDE, the prevalence of past year mental health treatment was greater among those with proximal transience compared with those without transience (AOR = 1.40, 95% CI = 1.15-1.70), but there was no significant difference in treatment among those with distal v. no transience. CONCLUSIONS: Distal and recent transience are associated with past year MDE among adolescents. Adolescents with MDE who had recent transience were more likely to receive past year mental health treatment compared with those without transience. However, those with only distal transience were not more likely to receive treatment. Parents, school officials and health care providers should be aware that residential mobility in the past 5 years may indicate increased odds of depression among adolescents even among adolescents whose housing stability has improved in the past year.

Renal tubular acidosis type IV as a complication of lupus nephritis.

Renal tubular acidosis (RTA) is a rare complication of renal involvement of systemic lupus erythematosus (SLE). We describe a 24-year-old male with type IV lupus nephropathy as a presenting manifestation of SLE. He presented with improvement of renal function following induction therapy with three pulses of methylprednisolone and 500 mg biweekly pulses of cyclophosphamide. However, a week after the first pulse of cyclophosphamide, the patient presented with a significant increase in legs edema and severe hyperkalemia. Type IV RTA associated with hyporeninemic hypoaldosteronism was suspected in the presence of metabolic acidosis with a normal anion gap, severe hyperkalemia without worsening renal function, and urinary pH of 5. RTA was confirmed with a transtubular potassium concentration gradient of 2 and low levels of plasma aldosterone, renin, angiotensin II, and cortisol. Intravenous bicarbonate, high-dose furosemide, and fludrocortisone were administered with normalization of potassium levels and renal function.

Assessment of off-label use of denosumab 60 mg injection during the early postmarketing period using health insurance claims data.

UNLABELLED: Off-label use of denosumab 60 milligram (mg) injection was assessed within an administrative claims database. The completeness of claims to assess off-label use was investigated with medical record review. Potential denosumab 60 mg off-label use was observed based on claims, but many had evidence of on-label indications based on medical record review. INTRODUCTION: Denosumab 60 mg injection is approved in the USA to treat patients at high fracture risk due to postmenopausal osteoporosis, male osteoporosis, and hormone therapy for the treatment of prostate and breast cancers. Its RANK ligand-inhibiting effect makes it a candidate for the off-label treatment of other conditions mediated by the rate of bone resorption by osteoclasts. To better understand its utilization patterns, we assessed off-label use of denosumab 60 mg within an administrative claims database. METHODS: Definite, probable, and possible denosumab 60 mg users were identified during the early postmarketing period within a claims database of a US healthcare insurer. Medical record review confirmed a sample of these users. Off-label use among definite and probable users and all chart-confirmed users was classified using claims-derived age, dose interval, and diagnosis and treatment received relative to the administration date. Among chart-confirmed users classified as off-label, patient characteristics related to treatment indication were abstracted from medical records to investigate the completeness of claims to study off-label medication use. RESULTS: Off-label use was identified based on claims in approximately 25 % of definite and probable denosumab 60 mg users and 35 % of chart-confirmed users. Medical record review identified evidence of on-label indications in 81 % of chart-confirmed users classified as off-label in claims. CONCLUSIONS: Many of the off-label denosumab 60 mg users had diagnoses or treatment consistent with on-label indications based on medical record review, suggesting these are under-recorded in claims data. It is warranted to be cautious when using administrative databases to assess off-label medication use.

A pilot study of personality pathology in patients with anorexia nervosa: modifiable factors related to outcome after hospitalization.

OBJECTIVE: To assess improvement in aspects of personality in patients hospitalized with anorexia nervosa (AN) and its relationship to improved depression, body mass index (BMI), and eating disorder outcome after treatment. METHOD: Twenty females hospitalized with AN completed intake and discharge assessments of BMI, depression and eating disorder severity, as well as personality pathology with the Minnesota Multiphasic Personality Inventory (MMPI-2) and the Revised NEO Personality Inventory (NEO PI-R). Clinical outcome for a subset of patients at 1-year post-hospitalization was determined. RESULTS: The only factor that predicted better versus worse outcome at 1-year post-hospitalization was change in Low Self-Esteem (LSE) from the MMPI-2. Improved LSE from admission to discharge predicted remission at 1-year post-hospitalization, while worsening LSE predicted relapse. Regardless of outcome, NEO PI-R Neuroticism remained pathologically elevated in AN patients during hospitalization. DISCUSSION: Pathological levels of neuroticism may represent a vulnerability factor for AN. In contrast, self-esteem appears to be a modifiable factor that predicts outcome following hospitalization, and may be an important target for treatment.

Code status discussions and goals of care among hospitalised adults.

BACKGROUND AND OBJECTIVE: Code status discussions may fail to address patients' treatment-related goals and their knowledge of cardiopulmonary resuscitation (CPR). This study aimed to investigate patients' resuscitation preferences, knowledge of CPR and goals of care. Design, setting, patients and measurements: 135 adults were interviewed within 48 h of admission to a general medical service in an academic medical centre, querying code status preferences, knowledge about CPR and its outcome probabilities and goals of care. Medical records were reviewed for clinical information and code status documentation. RESULTS: 41 (30.4%) patients had discussed CPR with their doctor, 116 (85.9%) patients preferred full code status and 11 (8.1%) patients expressed code status preferences different from the code status documented in their medical record. When queried about seven possible goals of care, patients affirmed an average of 4.9 goals; their single most important goals were broadly distributed, ranging from being cured (n = 36; 26.7%) to being comfortable (n = 8; 5.9%). Patients' mean estimate of survival to discharge after CPR was 60.4%. Most patients believed it was helpful to discuss goals of care (n = 95; 70.4%) and the chances of surviving in hospital CPR (n = 112; 83.0%). Some patients expressed a desire to change their code status after receiving information about survival following in hospital CPR (n = 11; 8.1%) or after discussing goals of care (n = 2; 1.5%). CONCLUSIONS: Doctors need to address patients' knowledge about CPR and take steps to avoid discrepancies between treatment orders and patients' preferences. Addressing CPR outcome probabilities and goals of care during code status discussions may improve patients' knowledge and influence their preferences.

Do faculty and resident physicians discuss their medical errors?

BACKGROUND: Discussions about medical errors facilitate professional learning for physicians and may provide emotional support after an error, but little is known about physicians' attitudes and practices regarding error discussions with colleagues. METHODS: Survey of faculty and resident physicians in generalist specialties in Midwest, Mid-Atlantic and Northeast regions of the US to investigate attitudes and practices regarding error discussions, likelihood of discussing hypothetical errors, experience role-modelling error discussions and demographic variables. RESULTS: Responses were received from 338 participants (response rate = 74%). In all, 73% of respondents indicated they usually discuss their mistakes with colleagues, 70% believed discussing mistakes strengthens professional relationships and 89% knew at least one colleague who would be a supportive listener. Motivations for error discussions included wanting to learn whether a colleague would have made the same decision (91%), wanting colleagues to learn from the mistake (80%) and wanting to receive support (79%). Given hypothetical scenarios, most respondents indicated they would likely discuss an error resulting in no harm (77%), minor harm (87%) or major harm (94%). Fifty-seven percent of physicians had tried to serve as a role model by discussing an error and role-modelling was more likely among those who had previously observed an error discussion (OR 4.17, CI 2.34 to 7.42). CONCLUSIONS: Most generalist physicians in teaching hospitals report that they usually discuss their errors with colleagues, and more than half have tried to role-model discussions. However, a significant number of these physicians report that they do not usually discuss their errors and some do not know colleagues who would be supportive listeners.

Eating disorder age of onset in males: distribution and associated characteristics.

The objective of this study was to determine the distribution of age of onset of eating disorders in males as well as the relationship between age of onset and various clinical and demographic characteristics. The medical records of 70 males consecutively admitted to an inpatient eating disorders unit between June of 1992 and June of 2002 were retrospectively reviewed. Age of onset did not significantly differ by admission diagnosis and appeared to have a single peak at about age 14. Inpatients with older ages of onset reported lower percentage of mean matched population weight (r=-0.35, p=0.005) and longer duration of illness (r=0.26, p=0.03) than inpatients with younger ages of onset. This study confirms the findings of previous investigations performed on female samples and also finds some unique aspects of males with eating disorders important to consider in prevention and treatment programs targeting male populations.

Lower TSH and higher T4 levels are associated with current depressive syndrome in young adults.

OBJECTIVE: The relationship of individual thyroid function indices to depression in those without a history of prior thyroid dysfunction is uncertain. METHOD: We examined the relationship between thyroid-stimulating hormone (TSH) and thyroxine (T4) levels and current or lifetime history of depressive symptoms using information from 6869 participants, aged 17-39 years, in the Third National Health and Nutrition Examination Survey without history of thyroid-related illness. RESULTS: We found that lower TSH and higher T4 levels were associated with current depressive syndrome in men, but only higher T4 levels correlated with current depressive syndrome in women. Lifetime depressive syndrome was associated with neither TSH level nor T4 levels in men or women. CONCLUSION: These findings suggest that transient or 'state dependent' changes are associated with depression in those without a history of thyroid illness. Further studies to discern whether these depression-associated changes represent distinct endophenotypes of depression should be encouraged.

Associations between medical service use and HIV risk among HIV-positive drug users in Baltimore, MD.

The objectives of this study were first, to identify psychosocial and medical service utilization factors associated with unprotected sex with HIV-negative or unknown serostatus partners among persons living with HIV/AIDS, and second, to identify risk behaviours associated with HIV medical service use. We assessed 244 HIV-positive participants in an HIV intervention targeting drug users (1997-99). Fifty-seven per cent of HIV-positive participants reported unprotected sex within the past 90 days, 16.4% with serodiscordant partners. Odds of risky sex were lower among those currently receiving HIV medical care (odds ratio (OR)=0.36), and were greater among females (OR=2.6), those having friends with lower norms of condom use (OR=3.3), and those having a main sexual partner (OR=6.2). Lower odds of receiving HIV medical care were associated with current drug use (OR=0.33), sharing drugs with a sex partner (OR=0.27), and exchanging sex for drugs or money (OR=0.24). Findings suggest the importance of community-based HIV prevention intervention targeting HIV-positive drug users not recovery HIV medical care.

First report of the giant kidney worm (Dioctophyme renale) in a harbor seal (Phoca vitulina).

A male harbor seal (Phoca vitulina) was found moribund on the coast of New Jersey in January of 2003 and died a few hours later in the Marine Mammal Stranding Center. On necropsy, a single female Dioctophyme renale was recovered from the peritoneal cavity, and a tissue mass was found adjacent to the pelvic urethra and urinary bladder. Within this tissue mass were found D. renale ova. This is the first report of this nematode in the harbor seal and in a North American marine mammal.

A 33-year follow-up of narcotics addicts.

BACKGROUND: This study examined longitudinal patterns of heroin use, other substance use, health, mental health, employment, criminal involvement, and mortality among heroin addicts. METHODS: The sample was composed of 581 male heroin addicts admitted to the California Civil Addict Program (CAP) during the years 1962 through 1964; CAP was a compulsory drug treatment program for heroin-dependent criminal offenders. This 33-year follow-up study updates information previously obtained from admission records and 2 face-to-face interviews conducted in 1974-1975 and 1985-1986; in 1996-1997, at the latest follow-up, 284 were dead and 242 were interviewed. RESULTS: In 1996-1997, the mean age of the 242 interviewed subjects was 57.4 years. Age, disability, years since first heroin use, and heavy alcohol use were significant correlates of mortality. Of the 242 interviewed subjects, 20.7% tested positive for heroin (with additional 9.5% urine refusal and 14.0% incarceration, for whom urinalyses were unavailable), 66.9% reported tobacco use, 22.1% were daily alcohol drinkers, and many reported illicit drug use (eg, past-year heroin use was 40.5%; marijuana, 35.5%; cocaine, 19.4%; crack, 10.3%; amphetamine, 11.6%). The group also reported high rates of health problems, mental health problems, and criminal justice system involvement. Long-term heroin abstinence was associated with less criminality, morbidity, psychological distress, and higher employment. CONCLUSIONS: While the number of deaths increased steadily over time, heroin use patterns were remarkably stable for the group as a whole. For some, heroin addiction has been a lifelong condition associated with severe health and social consequences.

Therapeutic developments in cytomegalovirus retinitis.

The incidence of cytomegalovirus (CMV) retinitis in AIDS has declined significantly due to the use of highly active antiretroviral therapy (HAART). However, patients with HIV, especially those failing HAART, may still suffer with CMV retinitis, which can lead to significant loss of vision and blindness. Ganciclovir has traditionally been considered the recommended treatment for CMV retinitis; however, due to side effects and the possibility of developing viral resistance, other agents may be preferred in certain situations. Foscarnet, which has similar efficacy to ganciclovir but a different side effect profile, is more difficult to administer and is less well-tolerated. Intravenous cidofovir, which may be more effective than either iv. ganciclovir or foscarnet, can also be used as a first line agent; however, it is associated with toxicity (renal and ocular) and thus needs careful use. Local therapy for CMV retinitis has been a significant advance. The intraocular ganciclovir implant has the highest efficacy of the approved agents and is well-tolerated. Fomivirsen, an oligonucleotide injected intravitreally, is a newly approved agent which offers alternative treatment. Intravitreal ganciclovir or foscarnet, although not approved, have been used successfully in some patients especially those with recurrent or refractory disease. The development of new anti-CMV agents has been stalled by the decreased incidence of the disease. Valganciclovir, a prodrug of ganciclovir, offers excellent oral bioavailability and is the closest to approval of all the new anti-CMV drugs. High ganciclovir blood levels are achieved without the complications associated with the requirement for long-term iv. access. The monoclonal antibody (mAb) MSL-109, did not offer a significant advantage when added to traditional anti-CMV therapy. Development plans of other agents such as cyclic HPMPC and lobucavir have been put on hold by their respective manufacturers. Adefovir is a nucleotide analogue that possesses anti-CMV activity, but is currently only being pursued for the treatment of hepatitis B virus. Other compounds possessing significant anti-CMV activity, including BAY 38-4766 and GW1263W94 are still in the early stages of development.

Cocaine use and high-risk sexual behavior among STD clinic patients.

BACKGROUND AND OBJECTIVES: Crack-smoking sexually transmitted disease (STD) patients are at high-risk for contracting HIV. GOAL OF THE STUDY: To examine the effects of cocaine use and other correlates on high-risk sexual behavior among STD clinic patients. STUDY DESIGN: This was a cross-sectional study of 1,490 consecutive patients attending three Los Angeles County STD clinics between 1992 and 1994. RESULTS: Logistic regression analysis found high-risk sexual activity was associated with being a male and being of younger age. Among women, high-risk sexual behavior was associated with crack cocaine use and a perceived need for help. Among the men in the study, ethnicity (being black) and having an arrest history were associated with high-risk behavior. CONCLUSIONS: Effective intervention strategies should address cocaine use among STD patients and provide them with referrals to drug treatment.

A night with Venus: partner assessments and high-risk sexual encounters.

This study examined partner assessments and high-risk sexual encounters among STD clinic patients. Participants were 42 English-speaking attendees of a public STD clinic in Southern California with ages ranging between 18 and 60. Twelve focus groups were conducted. Qualitative data from the focus groups were analyzed using grounded theory. The analysis resulted in delineating five temporally-ordered stages of causal sexual encounters. Participants reported that they did not use condoms when they perceived new sexual partners as being safe. Instead of directly addressing their partner's sexual history, they relied heavily on both visual and verbal cues to judge if their partner was clean, or disease-free. This assessment process reflects an error in judgement, particularly because most of the participants had already contracted a STD. Suggestions are provided for incorporating the information about the partner assessment process into AIDS educational programmes.

The gamesmanship of sex: a model based on African American adolescent accounts.

This article examines adolescent understanding of the social context of sexual behavior. Using grounded theory to interpret interviews with 39 African American male and female adolescents, the article builds a model of sex-related behavior as a set of interrelated games. A courtship game involves communication of sexual or romantic interest and, over time, formation of a romantic relationship. A duplicity game draws on conventions of a courtship game to trick a partner into having sex. A disclosure game spreads stories about one's own and other's sex-related activities to peers in a gossip network. Finally, a prestige game builds social reputation in the eyes of peers, typically based on gender-specific standards. The article concludes by examining the meanings that sex-related behavior may have for adolescents and the potential use of social knowledge for facilitating adolescent health.

Fidelity Management: African-American Adolescents' Attempts to Control the Sexual Behavior of their Partners.

This qualitative study examined how adolescents conceptualize sexual behavior. Open-ended interviews about sex were conducted with a sample of 21 male and 18 female African- American adolescents. Topics related to health risk virtually never emerged in their responses. The topic of partner infidelity and concerns about control of infidelity, on the other hand, were mentioned extensively. Informants described a cycle in which commitment to a partner often leads to suspicion of infidelity and jealousy. The jealous partner then performs acts of surveillance which can lead either to reassurance or to discovery of infidelity. The article concludes by discussing the degree of uniqueness of fidelity management to African- American adolescents and possible relevance to design of AIDS risk-reduction interventions.
