What happens to homeless mentally ill people? Follow up of residents of Oxford hostels for the homeless.

OBJECTIVES--To follow up severely mentally ill residents of hostels for the homeless to determine their social and psychiatric outcome. DESIGN--Follow up at 18 months of hostel residents previously assessed with psychiatric and behavioural measures. SETTING--Two Oxford hostels for the homeless. SUBJECTS--48 hostel residents previously identified as disabled by mental illness. MAIN OUTCOME MEASURES--Current housing, admissions to psychiatric hospital, violent or antisocial behaviour, and score on standardised behavioural rating. RESULTS--45 of the 48 residents were traced. 27 had remained in the hostels; only 10 had been rehoused, mainly in bedsits or with their families. 16 had a poor outcome as judged by death (four subjects), lengthy hospital readmission (two), marked deterioration in behaviour (six), sleeping rough (one), or disappearance (three). CONCLUSION--More effort is needed to provide suitable housing for homeless mentally ill people.     

Reaching impaired populations with HIV prevention programs: a clinical trial for homeless mentally ill African-American men.

This study tested an intervention to reduce sexual risk behaviors in a high risk impaired population: homeless African-American, Caucasian and Hispanic men with mental illness. In a comparison group clinical trial, men were assigned to an experimental cognitive-behavioral or a control intervention and followed up over 16 months. Men were recruited from a psychiatric program in two shelters for homeless men in Nashville, Tennessee. An ethnically mixed cohort of subjects (54% African-American, 42% Caucasian and 4% Hispanic) were included in the study. Most had a chronic psychiatric disorder and a co-morbid substance abuse disorder. The 257 participants who were sexually active (130 experimental, 127 control) prior to the trial were the main target of the intervention. An experimental intervention (SexG), adapted from Susser and Associates (51), comprised 6 group sessions. The control intervention was a 6-session HIV educational program. Sexual risk behavior was the primary outcome. The experimental and control groups were compared with respect to the mean score on a sexual risk index. Complete follow-up data were obtained on 257 men (100%) for the initial six-month follow-up. These individuals have been followed for the remainder of the 16-month follow-up. This intervention, (SexG), successfully reduced sexual risk behaviors of homeless mentally ill African-American, Caucasian and Hispanic men. Similar approaches may be effective in other impaired high-risk populations.     

Prevalence of Mental Illness among Homeless People in Hong Kong

MetholodogyThis study examined the prevalence and correlates of mental illness in homeless people in Hong Kong and explored the barriers preventing their access to health care. Ninety-seven Cantonese-speaking Chinese who were homeless during the study period were selected at random from the records of the three organisations serving the homeless population. The response rate was 69%. Seventeen subjects could not give valid consent due to their poor mental state, so their responses were excluded from the data analysis. A psychiatrist administered the Structured Clinical Interview for DSM-IV Axis-I disorders (SCID-I) and the Mini -Mental State Examination. Consensus diagnoses for subjects who could not complete the SCID-I were established by three independent psychiatrists.FindingsThe point prevalence of mental illness was 56%. Seventy-one percent of the subjects had a lifetime history of mental illness, 30% had a mood disorder, 25% had an alcohol use disorder, 25% had a substance use disorder, 10% had a psychotic disorder, 10% had an anxiety disorder and 6% had dementia. Forty-one percent of the subjects with mental illness had undergone a previous psychiatric assessment. Only 13% of the subjects with mental illness were receiving psychiatric care at the time of interview. The prevalence of psychotic disorders, dementia and the rate of under treatment are hugely underestimated, as a significant proportion (18%) of the subjects initially selected were too ill to give consent to join the study.ConclusionThe low treatment rate and the presence of this severely ill and unreached group of homeless people reflect the fact that the current mode of service delivery is failing to support the most severely ill homeless individuals.     

Gender Differences in patient-provider symptom agreement in reporting respiratory complaints on a questionnaire

Background: Men and women communicate differently, but it is unclear whether this influences health care outcomes.Objective: Because women patients frequently choose women health care providers, we examined whether this preference was affected by communication styles. We focused on communication of disease-specific symptoms, hypothesizing that symptom agreement between women patients and women health care providers would be greater than between other patient-provider gender combinations.Methods: Patients attending outpatient clinics were recruited as part of a study of respiratory illness at 7 university-affiliated sites during 3 consecutive influenza seasons (2000–2003). Individuals aged ≥ 19 years were offered enrollment if they sought care for cold or flu symptoms at a participating study site. Patients were eligible to participate in the study if they reported any 1 of 6 symptoms: cough, runny nose, fever (subjective), muscle aches, sore throat, and/or exhaustion. Using separate questionnaires, patients and their health care providers recorded the patients' respiratory symptoms (as present or absent). Patients recorded their symptoms before visiting their health care provider, and providers recorded patient symptoms after the visit. Symptom agreement was compared using general estimating equations across all gender combinations.Results: A total of 327 patients (220 women, 107 men) and 84 health care providers (37 women, 47 men) participated in the study. Overall symptom agreement for all patient-provider gender combinations was 81.9% (95% CI, 79.6%–84.2%). For each symptom, the observed agreement significantly exceeded the agreement expected by chance alone (P < 0.001 for all symptoms except “no energy,” which was P = 0.023). The male-male pairing of patient and provider was more likely to agree on a symptom than were the other gender combinations, although not statistically significantly more so than the female-female pairing.Conclusions: In this survey of patients with respiratory illness, there was no significant difference in symptom agreement for most symptoms between the male-male and female-female patient-provider combinations. Based on these findings, symptom agreement alone does not explain why women patients select women health care providers.     

Sex differences in the pharmacokinetics and pharmacodynamics of antidepressants: An updated review

Background: An increasing number of studies have reported differences in the pharmacokinetics and/or pharmacodynamics of antidepressants between women and men.Objectives: This article updates previously published literature describing sex differences in the pharmacokinetics and pharmacodynamics of antidepressants, and examines specific issues that face women with psychiatric illness.Methods: An English-language literature search was performed with the PubMed database (March 2003–December 2008) using combinations of the search terms sex, gender, and antidepressants. In addition, each antidepressant was identified in the 63rd edition of the Physicians' Desk Reference.Results: The current data suggest that the pharmacokinetics of antidepressants can be substantially different between women and men. Likewise, the response to antidepressants can be quite variable, including sex differences in adverse effects and time to response.Conclusions: Despite the many sex differences reported, there is still little published work systematically evaluating potential sex differences in antidepressant pharmacokinetics and pharmacodynamics. More research is needed to guide the treatment of depression and other mental illnesses.     

Health-related quality of life in Swedish men and women with early rheumatoid arthritis

Background: Rheumatoid arthritis (RA) is a chronic inflammatory joint disorder that may adversely affect health-related quality of life (HRQoL) both in established and early disease.Objectives: In patients with recent onset (<12 months) of RA, this extension of a previous study assessed HRQoL and the effect of disease activity over time.Methods: Consecutive patients with recent onset of RA between March 1996 and November 1998 were followed for 6 years at the Department of Rheumatology of the University Hospital of Umeå in Sweden. Patients were requested to complete the 36-item Short Form (SF-36) Health Survey at 0, 24, 48, and 72 months. Gender differences were examined, and correlations between the SF-36 scales (with higher scores indicating better HRQoL) and data reflecting disease activity were analyzed.Results: Fifty-one patients, 34 women and 17 men (mean age, 50.6 years; range, 20–78 years), participated in the study; in all, 41 patients completed the SF-36 at both 0 and 72 months. At inclusion (0 months), women reported significantly higher scores for physical role functioning, bodily pain, and social functioning compared with men (all, P < 0.05). At 72 months compared with 0 months, women reported significantly better mental health (P < 0.05), whereas men reported significantly better physical role functioning (P < 0.05), bodily pain (P < 0.01), mental health (P < 0.01), and vitality (P < 0.01). Additionally, at 72 months, the entire patient group rated physical role functioning and social functioning (both, P < 0.05), bodily pain and vitality (both, P < 0.01), and mental health (P < 0.001) as significantly better compared with the inclusion assessment. Overall improvement with time was significantly better for men than for women (P < 0.05). There were limited correlations between SF-36 point disease activity parameters and the SF-36 scores at 0 months (erythrocyte sedimentation rate vs physical functioning, mental health [both, P < 0.05], and bodily pain [P < 0.01]; 28-joint Disease Activity Score vs bodily pain [P < 0.05] and emotional role functioning [P < 0.01]) and at 72 months (C-reactive protein vs physical role functioning [P < 0.05]). Most of the physical subscales at inclusion correlated with the physical component summary (PCS) of the SF-36 questionnaire at 6 years.Conclusions: At disease onset, women with early RA reported better HRQoL than did their male counterparts. After 6 years, women and especially men both experienced better HRQoL, and no significant gender differences remained in any of the SF-36 scales or values for disease activity parameters. The PCS score at disease onset was the best predictor of the PCS score after 6 years.     

Sex differences in the clinical and serologic presentation of early lyme disease: Results from a retrospective review

Background: Lyme disease is the most common vector-borne disease in the United States, and the number of reported cases has more than doubled between 1992 and 2008. Few studies have explicitly examined sex-based differences in the clinical presentation of or serologic response to early Lyme disease. It is unknown whether the sex-based variability observed in other infectious diseases is relevant to this clinical setting.Objective: This study retrospectively examined clinical and serologic differences by sex among a community case series of patients with a current or past episode of confirmed early Lyme disease.Methods: This was a retrospective, consecutive case series of adult patients in Maryland enrolled from August 2002 to August 2007 meeting criteria for a current or past episode of confirmed early Lyme disease. Clinical variables and patients' self-report surrounding illness onset were abstracted through chart review. All serologic tests drawn within 3 months of illness onset were interpreted using Centers for Disease Control and Prevention criteria.Results: In a total of 125 patients, there were no significant differences in clinical presentation by sex. The initial self-misdiagnosis rates for men and women were 10% and 18%, respectively (P = NS). Among the 62 patients with a serologic test as part of their clinical evaluation, 50% of men had a positive, 2-tier result compared with 32% of women (P = NS). Among the 41 patients with a positive ELISA, median ELISA values (3.4 vs 2.0; P = 0.03) and median number of immunoglobulin G (IgG) bands (4 vs 2; P = 0.03) were significantly higher among men.Conclusions: In this small, retrospective sample, we found evidence for sex-based differences in the magnitude of ELISA and IgG serologic response to early Lyme disease. Such differences could have implications for appropriate diagnosis, treatment, and disease classification. Larger, prospective studies are needed to replicate the results found in this study and to examine their relationship to sex-based immunologic variability.     

Gender differences in self-rated health,quality of life,quality of care,and metabolic control in patients with diabetes

Background: Because the projected increase in the number of diabetic patients is expected to strain the capabilities of health care providers worldwide, we are challenged to find ways of reducing the burden of diabetes. Maintaining and improving health-related quality of life (QoL) for diabetic patients may be viewed as public health goals.Objective: The aim of this cross-sectional study was to compare different aspects of health, QoL, and quality of care (QoC) between men and women with diabetes as a basis for planning and managing diabees care.Methods: All patients in 2 age groups (aged 20–30 years [younger age group] and aged 50–60 years [middle-aged group]) who were registered with the Department of Endocrinology, Metabolism, and Diabetes at Karolinska University Hospital, Stockholm, Sweden, in October 2004, were recruited for a survey. Questions were included about self-rated health (SRH), QoL, QoC, diabetes-related worries, occupational status, physical activity level, living arrangements, and educational background. Glycosylated hemoglobin (HbA_1c) values were obtained from medical records.Results: Of the 223 eligible patients (109 men, 114 women) in the younger age group, 49 men and 74 women responded to the questionnaire; of the 300 eligible patients (170 men, 130 women) in the middle-aged group, 120 men and 93 women responded. Middle-aged women rated their mental well-being and QoL as worse compared with men (P < 0.001 and P < 0.05, respectively). In both age groups, women reported more diabetes-related worries and less ability to cope (P < 0.05 for the younger age group and P < 0.001 for the middle-aged group for both variables), thus the differences were more marked for middleaged women. Although there were no gender differences in metabolic control, middle-aged women reported less satisfaction with diabetes care (P < 0.001). Higher HbA_1c was related to worse SRH in both men and women when analyzing the age groups together (P < 0.05). This association was most prominent in young women, in whom having more diabetes-related worries was also related to higher HbA_1c (P < 0.01).Conclusion: In this study, women with diabetes appeared to have worse QoL and mental well-being compared with men with diabetes. Therefore, identifying strategies to improve SRH and QoL among diabetic patients, especially among women, is of great importance.     

Effects of gender and depression on oral medication adherence in persons with type 2 diabetes mellitus

Background: In a range of chronic conditions including diabetes, it has been observed that depressive symptoms may be associated with nonadherence to medications.Objective: The objective of the study was to determine the main effects, and interactive effect, of depression and gender on patients adherence to oral diabetes medications.Methods: A cross-sectional design was employed, in which persons with type 2 diabetes mellitus completed a questionnaire regarding medication use behaviors, depressive symptoms (measured by the 8-item Patient Health Questionnaire [PHQ-8]), health beliefs, and demographics. A 2 x 2 factorial analysis of variance was used to determine the effects of gender and depression on medication adherence after adjusting for age, education, self efficacy, social support, and number of doses of diabetes medications.Results: Of the 391 respondents who completed the questionnaire, 73 (18.7%) were categorized as having depression (ie, PHQ-8 score >10). Overall, women (n = 196) had a mean (SD) score of 6.10 (6.19) on the PHQ-8, and men (n = 195) had a lower score of 4.62 (5.28) (t = 2.75; P < 0.01). There was a significant main effect of depression, but not gender, on patients' adherence to diabetes medications in that those who were categorized as depressed had significantly worse adherence to diabetes medications (F = 4.82; P = 0.03).Additionally, there was a significant “gender x depression” interaction effect on adherence (F = 5.93; P = 0.01). Men with depression had mean adherence scores that indicated more nonadherence than did men without depression (9.44 [3.45] vs 7.47 [2.50], respectively), but adherence varied little between women with depression and women without depression (7.83 [2.69] vs 7.55 [2.58], respectively).Conclusions: The association between depression and medication adherence appears to be stronger in men than in women. Clinicians should be cognizant of the potential effect of depression on self-care for diabetes, particularly in men with depressive symptoms.     

Estimating numbers of homeless and homeless mentally ill people in north east Westminster by using capture-recapture analysis.

OBJECTIVES--To use routinely collected data to provide a reliable estimate of the size and psychiatric morbidity of the homeless population of a given geographical area by using capture-recapture analysis. DESIGN--A multiple sample, log-linear capture-recapture method was applied to a defined area of central London during 6 months. The method calculates the total homeless population from the sum of the population actually observed and an estimate of the unobserved population. Data were collected from local agencies used by homeless people. SUBJECTS--Homeless people in north east Westminster residing in bed and breakfast accommodation and hotels or sleeping rough who had contacted statutory or voluntary agencies in the area. RESULTS--2150 contacts by 1640 homeless people were recorded. The estimated unobserved population was 3293, giving a total homeless population for the period of around 5000 (SD 1250). Mental health problems were significantly less prominent in the unobserved compared with the observed population (23% (754) v 40% (627), P < 0.0001). For both groups the prevalence varied greatly with age and sex. CONCLUSIONS--Capture-recapture techniques can overcome problems of ascertainment in estimating populations of homeless and homeless mentally ill people. Prevalences of mental illness derived from surveys that do not correct for ascertainment are likely to be falsely inflated while at the same time underestimating the total size of the homeless mentally ill population. Population estimates derived from capture-recapture techniques may usefully provide a good basis for including homeless populations in capitation calculations for allocating funds within health services.     

Community Attitude and Associated Factors towards People with Mental Illness among Residents of Worabe Town,Silte Zone,Southern Nation’s Nationalities and People’s Region,Ethiopia

Background

Mental illnesses worldwide are accompanied by another pandemic, that of stigma and discrimination. Public understanding about mental illnesses and attitudes towards people with mental illness play a paramount role in the prevention and treatment of mental illness and the rehabilitation of people with mental illness.

Objective

To assess community attitude and associated factors towards people with mental illness.

Methods

Community based cross-sectional study was conducted from April 28 to May 28, 2014. Quantitative data were collected through interview from 435 adults selected using simple random sampling. Data were collected using community attitude towards mentally ill (CAMI) tool to assess community attitude towards people with mental illness and associated factors. Multiple linear regression analysis was performed to identify predictors of community attitude towards people with mental illness and the level of significance association was determined by beta with 95% confidence interval and P less than 0.05.

Results

The highest mean score was on social restrictiveness subscale (31.55±5.62). Farmers had more socially restrictive view (β = 0.291, CI [0.09, 0.49]) and have less humanistic view towards mentally ill (β = 0.193, CI [-0.36, -0.03]). Having mental health information had significantly less socially restrictive (β = -0.59, CI [-1.13, -0.05]) and less authoritarian (β = -0.10, CI [-1.11, -0.06]) view towards mentally ill but respondents who are at university or college level reported to be more socially restrictive (β = 0.298, CI [0.059, 0.54]). Respondents whose age is above 48 years old had significantly less view of community mental health ideology (β = -0.59, CI [-1.09, -0.08]).

Conclusion and Recommendation

Residents of Worabe town were highly socially restrictive but less authoritarian. There was high level of negative attitude towards people with mental illness along all the subscales with relative variation indicating a need to develop strategies to change negative attitude attached to mental illness in Worabe town at community level.     

Si Dios Quiere: Hispanic families' experiences of caring for a seriously mentally ill family member

Among Hispanics, the family is viewed as the primary care giver for seriously mentally ill family members. This paper reports on a study of minority families' conceptions of serious mental illness, of their interaction with mental health resources, and on the burdens experienced by families in caring for a seriously mentally ill family member. The focus of this paper is on Hispanic families in New Jersey, with some comparative data from other ethnic group families. Families' conceptions of serious mental illness are explored and analyzed to demonstrate the importance of concepts of nervios and fallo mental in shaping families' responses to their ill family member. Social support systems for families are also explored with particular attention to the role of religious institutions and religious healing as a major source of solace.     

Gender distribution in irritable bowel syndrome is proportional to the severity of constipation relative to diarrhea

Background: A significant gender disparity has been observed in individuals with irritable bowel syndrome (IBS), with females outnumbering males, especially in constipation-predominant IBS (C-IBS). However, this observation is based on Rome criteria categorization and does not take into account the severity of constipation or diarrhea.Objective: In a large prospective data set, gender differences across the severity of constipation and diarrhea were examined in patients with IBS.Methods: Consecutive adult patients with Rome I positive IBS who were referred to a tertiary care medical center (Cedars-Sinai Medical Center, Los Angeles, California) in 1999–2003 were given a questionnaire. The questionnaire asked subjects to rate their constipation and diarrhea according to perceived severity using a scale from 0 (none) to 5 (very severe). C-IBS was determined to be present if the severity of constipation was greater than the severity of diarrhea (sevC > sevD). If sevD > sevC, subjects were considered to have diarrhea-predominant IBS (D-IBS). To further categorize their symptoms, subjects were then grouped by the difference between the severity of constipation and diarrhea, creating a range of values from ?5 to +5. For each of these 11 constipation/diarrhea severity values, the female:male ratio was determined. The severity of constipation to diarrhea was compared by Spearman rank correlation.Results: A total of 429 subjects with IBS (325 women: mean [SD] age, 42.5 [0.8] years; 104 men: mean age, 42.2 [1.7] years) completed the questionnaire. Constipation occurred more frequently in women (79.7%) compared with men (61.5%) (odds ratio [OR] = 2.49; 95% CI, 1.55–4.02). The prevalence of diarrhea was similar between the sexes. Whereas C-IBS was more common in women (31.8%) than in men (26.0%) (OR = 2.03; 95% CI, 1.24–3.30), D-IBS was more prevalent in men (62.5%) than in women (36.3%) (OR = 2.39; 95% CI, 1.53–3.75). When the female:male ratio was evaluated across the 11 severity score categories of constipation and diarrhea, the greater the sevC — sevD score, the higher the proportion of women (R = 0.80; P = 0.003).Conclusion: In this study of patients with IBS, the observation of the association of constipation and gender in IBS is extended to indicate that the female:male ratio significantly increases according to the severity of constipation relative to the severity of diarrhea.     

Gender differences in psychosocial responses to lung cancer

Background: Although biologically based sex differences in the smoking patterns, epidemiology, biomedical markers, and survival rates associated with lung cancer are well documented, examinations of psychosocial gender differences are scarce.Objective: This cross-sectional study examined gender differences in psychosocial factors that are important in the medical management of lung cancer.Methods: A convenience sample of patients who were attending a multidisciplinary lung cancer treatment center (Markey Cancer Center, Lexington, Kentucky) were invited to complete a psychosocial needs assessment. Eligibility criteria included primary diagnosis of lung cancer, age ≥18 years, and being cognitively intact. Measures focused on psychosocial resources, treatment decision-making, social consequences of treatments, and treatment outcomes. Data were collected between the fall of 2005 and the summer of 2006.Results: A total of 47 women and 53 men (mean [SD] age, 62.81 [12.01] years; 95% white) completed the needs assessment. Gender was not found to be associated with demographic characteristics, time until diagnosis, treatment, or survival rate. Smoking histories differed significantly in the proportion of women and men who smoked or were former smokers (P = 0.01) as well as the age when they began to smoke (P = 0.02). There were no significant gender differences in social support networks, general coping, information needs, treatment decision satisfaction, functional health, life satisfaction, financial impact, or service needs. However, significant gender differences did indicate that women favored spiritual practices (P = 0.02) and religious coping (P = 0.04), and were more likely to endorse having a life mission (P = 0.03) and being part of a divine plan (P = 0.01).Conclusions: Previous research has found that religiousness and spirituality improved depressive symptoms and may ease end-of-life despair. In the present study of patients with lung cancer, gender differences in religiousness and spirituality suggest that this may be especially true for women, and that interventions should be directed toward their religious practices and coping.     

Gender as a determinant of responses to a self-screening questionnaire on anxiety and depression by patients with coronary artery disease

Background: Because patients with coronary artery disease (CAD) could benefit from interventions to decrease psychological distress, it is important to identify these individuals. Both salivary cortisol level and the Hospital Anxiety and Depression Scale (HADS) are recognized measures of stress/anxiety and depression.Objectives: This study was designed to determine whether there is an association between anxiety and depression, as measured by the HADS, and salivary cortisol levels among patients with CAD, and whether this association is affected by gender.Methods: All adult residents of Alberta, Canada, undergoing their first cardiac catheterization for CAD (≥50% occlusion of ≥2 coronary arteries) were eligible for participation in this study. A 14-question survey (the HADS) and 3 saliva-collection devices (a 1-day supply) were sent to the participants' home within 1 week of their initial cardiac catheterization. Participants were asked to take saliva samples for determination of cortisol levels on waking and at 30 and 60 minutes after waking, and then return the completed questionnaire and saliva samples using a prepaid express mailing envelope.Results: Seventy-one adults (52 men and 19 women) participated in the study. Mean (SD) ages were 68.4 (4.6) years for men and 69.1 (4.4) years for women. Among the women, significant negative correlations were found between the HADS anxiety score and the wake-up and 30-minute cortisol levels (higher HADS scores were associated with lower cortisol levels) (all, P < 0.05). Also among women, negative correlations were found between the HADS depression score and the salivary cortisol values, but the differences were not statistically significant. Conversely, among the men, nonsignificant positive correlations were found between the HADS anxiety scores and the salivary cortisol levels (higher HADS scores were associated with higher cortisol levels), and statistically significant positive correlations were observed between the HADS depression scores and all 3 salivary cortisol values (all, P < 0.05).Conclusions: Our findings suggest that the HADS is an appropriate screening instrument for anxiety and depression in patients with CAD. In particular, the scale appears to be sensitive for measuring anxiety in women and depression in men. When the HADS is used clinically as a screening tool, it should be examined through a “gender-based lens.”.     

Relationship between serum progesterone concentrations and cardiovascular disease,diabetes, and mortality in elderly Swedish men and women: An 8-Year prospective study

Background: The use of synthetic progesterone-like substances in hormone replacement therapy and birth control pills has been associated with increases in cardiovascular morbidity and the prevalence of diabetes.Objectives: The primary aims of this study were to investigate whether physiologic concentrations of progesterone might also be associated with cardiovascular disease and diabetes, and to explore potential gender differences in these associations in elderly Swedish men and women.Methods: This prospective, longitudinal study was performed in a Swedish population-based sample of opposite-sex twins aged between 71 and 80 years who were not receiving sex hormone therapy. Serum concentrations of progesterone, estradiol, C-reactive protein (CRP), and urea were measured at baseline (1996) and at 8-year follow-up (2004), and serum concentrations of cystatin and insulin were measured only at follow-up. The outcomes of interest were cardiovascular morbidity (myocardial infarction, angina pectoris, peripheral arterial disease, stroke, congestive heart failure [CHF], cardiac arrhythmia, hypertension, and thromboembolism), diabetes, and mortality throughout the observation period.Results: At baseline, the study sample included 230 men and 195 women (mean [SD] age, 74.6 [2.6] years). At follow-up, 132 men and 145 women (mean age, 82.4 [2.5] years) met the inclusion criteria, of whom 128 men and 112 women did so at both baseline and follow-up. Serum progesterone concentrations, which did not differ significantly from reported concentrations for the age group, were significantly associated with mortality across the observation period (P < 0.001). At follow-up, higher serum progesterone was significantly associated with the occurrence of CHF (P < 0.01); this association remained robust after adjustment for CRP, cystatin, and insulin levels.Conclusion: In these elderly Swedish men and women, increased physiologic concentrations of progesterone were found to be associated with an increased prevalence of CHF, independent of inflammatory factors, markers of renal function, and insulin metabolism.     

Sex differences in prefrontal hemodynamic response to mental arithmetic as assessed by near-infrared spectroscopy

Background: Sex differences in cognitive tasks have been widely investigated. With brain-imaging techniques, the functions of the brain during the performance of tasks can be examined.Objective: Mental arithmetic and near-infrared spectroscopy (NIRS) were used to assess sex differences in prefrontal area activation in a functional brain study.Methods: Healthy college students were recruited to perform 2 mental arithmetic tasks. In the first (easy) task, students had to subtract a 1-digit number from a 3-digit number. In the second (difficult) task, they had to subtract a 2-digit number from a 3-digit number. Changes in the concentration of oxygenated hemoglobin (oxy-Hgb) in the prefrontal area during the tasks were measured with NIRS.Results: Thirty students (15 men, 15 women; mean [SD] age: 24.9 [2.2] and 24.3 [2.6] years, respectively) were recruited from Southeast University, Nanjing, China, to participate in the study. The concentration of oxy-Hgb increased during both mental arithmetic tasks (difficult task vs easy task, mean [SD] % arbitrary units: 4.36 [4.38] vs 2.26 [2.82]; F_1,28 = 222.80; P < 0.01). Significant interactions of task x sex (F_1,28 = 82.95), time × sex (F_1,28 = 34.48), task × time (F_1,28 = 222.57), and task × time × sex (F_1,28 = 83.09) were obtained (all, P < 0.01). However, for the 2 tasks, no significant differences between men and women were observed in the mean (SD) response time (men vs women, sec: 3.60 [0.74] vs 3.56 [0.49] for the easy task, 6.55 [0.77] vs 6.44 [0.75] for the difficult task; F_1,28 = 0.67; P = NS) or accuracy rate (men vs women, %: 95.33 [7.40] vs 92.77 [8.80] for the easy task, 62.67 [28.56] vs 54.67 [18.75] for the difficult task; F_1,28 = 0.54; P = NS). Male students showed neural efficiency (less prefrontal activation in subjects with better performance) during the difficult task.Conclusions: In these subjects, sex differences in prefrontal response when performing mental arithmetic were associated with the intensity of the task. Compared with men, women had greater efficiency in task performance (ie, less activation or oxygen consumption for equal performance).     

<Emphasis Type="Italic">Guan</Emphasis> (Care/Control): An Ethnographic Understanding of Care for People with Severe Mental Illness from Shanghai’s Urban Communities

This article investigates how the political culture of Guan (care/control) in China is played out across the platforms of the state, the community and the family through the lens of caring for people with severe mental illness in urban Shanghai. Based on ethnographic data collected from six communities in a district of Shanghai, we provide a nuanced understanding of the roles of family members, street committees and other governmental organizations in their daily practices of caring for people with severe mental illness. We show the complicated and intertwined relationships between local governmental agents and the family. We argue that the political culture of Guan, which permeates the everyday life of Chinese people, tends to objectify its subjects and reflects a long history of patriarchy in Chinese society. Without further changing such political cultural arrangements, respect for the agency of mentally ill patients, the effort of bringing humanistic psychiatric reforms to China, will be in vain.
