Where do people go for treatment of sexually transmitted diseases?

CONTEXT: Major public health resources are devoted to the prevention of sexually transmitted diseases (STDs) through public STD clinics. However, little is known about where people actually receive treatment for STDs. METHODS: As part of the National Health and Social Life Survey, household interviews were performed from February to September 1992 with 3,432 persons aged 18-59. Weighted population estimates and multinomial response methods were used to describe the prevalence of self-reported STDs and patterns of treatment utilization by persons who ever had a bacterial or viral STD. RESULTS: An estimated two million STDs were self-reported in the previous year, and 22 million 18-59-year-olds self-reported lifetime STDs. Bacterial STDs (gonorrhea, chlamydia, nongonococcal urethritis, pelvic inflammatory disease and syphilis) were more common than viral STDs (genital herpes, genital warts, hepatitis and HIV). Genital warts were the most commonly reported STD in the past year, while gonorrhea was the most common ever-reported STD. Almost half of all respondents who had ever had an STD had gone to a private practice for treatment (49%); in comparison, only 5% of respondents had sought treatment at an STD clinic. Respondents with a bacterial STD were seven times more likely to report going to an STD clinic than were respondents with a viral STD--except for chlamydia, which was more likely to be treated at family planning clinics. Men were significantly more likely than women to go to an STD clinic. Young, poor or black respondents were all more likely to use a family planning clinic for STD treatment than older, relatively wealthy or white respondents. Age, sexual history and geographic location did not predict particular types of treatment-seeking. CONCLUSIONS: The health care utilization patterns for STD treatment in the United States are complex. Specific disease diagnosis, gender, race and income status all affect where people will seek treatment. These factors need to be taken into account when STD prevention strategies are being developed.     

Where do tuberculosis patients go for treatment before reporting to DOTS clinics in southern Nigeria?

Health-seeking patterns of persons with tuberculosis (TB) before reporting at the Directly Observed Treatment Short-course (DOTS) clinic for diagnosis and treatment were analysed. A total of 221 persons registered in the DOTS programme in 12 randomly selected rural and urban Local Government Areas in southern Nigeria were interviewed using a semi-structured questionnaire. Perceived causes of TB influenced first choice of treatment. Patients re-evaluated initial choices and shop for alternatives in persistent TB. Chemists were the first port of call for most patients. Those with unscientific causative theories of tuberculosis such as witchcraft engaged more in multiple health-seeking than those who indicated bacterial infection (P < 0.0001). The respondents had a median diagnostic-delay of 90 days. Delay in commencement of DOTS treatment was attributable to ignorance among patients and poor attitude of health workers. In conclusion, delay exists between recognition of symptoms and initiation of treatment in DOTS clinics partly because of ignorance among patients. Health workers' attitude to patients reporting at health clinics also discouraged the use of DOTS facilities. Consequently, it is recommended to address such delay through social mobilization of communities and through engaging Chemists in TB service delivery in this area.     

Are Australian immigrants at a risk of being physically inactive?

Background

As few longitudinal studies have examined how active transport is associated with physical activity among children and adolescents over time, and how active transport tracks through childhood and adolescence, it is important to understand whether physically active children retain their activity patterns through adolescence. This study aimed to examine (a) tracking of active transport and of moderate-to-vigorous physical activity (MVPA) across childhood and adolescence in two age cohorts; and (b) associations between active transport and MVPA at three distinct time-points, over five years.

Methods

This longitudinal study of two cohorts aged 5-6 years (n = 134) and 10-12 years (n = 201) at baseline (T1), in Melbourne, Australia, gathered follow-up data at three (T2) and five years (T3). Walking/cycling to local destinations was survey-reported; while MVPA was recorded using accelerometers and mean time spent daily in MVPA on week days and on weekends was computed. Tracking of these behaviours was examined over five years using General Estimating Equations. Linear regression analyses were performed to examine associations between active transport and MVPA at each time-point.

Results

Active transport tracked moderately among children (boys, β_s = 0.36; girls, β_s = 0.51) but not among adolescents. Physical activity tracked moderately (β_s value range: 0.33-0.55) for both cohorts. Active transport was not associated with children's MVPA at any time-point, but was associated with adolescent boys' MVPA on week days at T1 (B = 1.37 (95% CI: 0.15, 2.59)), at T2 (B = 1.27 (95% CI: 0.03, 2.51)) and at T3 (B = 0.74 (95% CI: 0.01, 1.47)), and with adolescent girls' MVPA on week days (B = 0.40 (95% CI: 0.04, 0.76)) and on weekends (B = 0.54 (95% CI: 0.16, 0.93)) at T3 only.

Conclusion

Active transport was associated only with boys' MVPA during early adolescence and with boys' and girls' MVPA during late adolescence. While active transport should be encouraged among all school-aged children, it may provide an important source of habitual physical activity for adolescent girls, in particular, among whom low and declining physical activity levels have been reported world-wide.     

Who is at risk of 13-valent conjugated pneumococcal vaccine failure?

BackgroundDespite high vaccine coverage rates in children and efficacy of pneumococcal conjugate vaccines, invasive pneumococcal disease (IPD) episodes due to serotypes included in the vaccine following completion of the recommended course of immunisation (i.e. vaccine failure) have been reported.MethodsWe used data gathered from a population-based enhanced passive surveillance for IPD in children under 18 years of age in Massachusetts and an ensemble model composed of three machine-learning algorithms to predict probability of 13-valent pneumococcal conjugated vaccine (PCV13) failure and to evaluate potential associated features including age, underlying comorbidity, clinical presentation, and vaccine schedule. Vaccine failure was defined as diagnosis of IPD due to vaccine serotype (VST), in a child who received age recommended doses recommended by Advisory Committee of Immunization Practices.ResultsDuring the 7-year study period, between April 01, 2010 and March 31, 2017, we identified 296 IPD cases. There were 107 (36%) IPD cases caused by VST, mostly serotype 19A (49, 17%), 7F (21, 7%), and 3 (18, 6%). Thirty-seven (34%) were in children who were completely vaccinated representing 13% of all IPD cases. Vaccine failure was more likely among children older than 60 months (predicted probability 0.40, observed prevalence 0.37, model prediction accuracy 79%), children presenting with pneumonia (predicted probability 0.27, observed prevalence 0.31, model accuracy 77%), and children with underlying comorbidity (predicted probability 0.24, observed prevalence 0.23, model accuracy 96%). Vaccine failure probability for those >60 months of age and had an underlying risk factor was 45% (observed prevalence 0.33, model accuracy 82%). The likelihood of vaccine failure was lowest among children who had completed 3 primary doses plus one booster dose PCV13 (predicted probability 0.14, observed prevalence 0.14, model prediction accuracy 100%).ConclusionPCV13 vaccine failure is more frequent among older children with underlying comorbidity, and among those who present with pneumococcal pneumonia. Our study provides a preliminary framework to predict the patterns of vaccine failures and may contribute to decision-making processes to optimize PCV immunization schedules.     

Should years of schooling be used to guide treatment of coronary risk factors?

PURPOSE: We wanted to compare the risk of death from coronary heart disease (CHD) for patients of low socioeconomic status, measured by educational level, with established risk factors. METHODS: We undertook a prospective cohort study. Participants included a representative sample of 6,479 adults aged 25 to 74 years in the United States who were free of CHD at enrollment in the first National Health and Nutrition Examination Survey (NHANES I). RESULTS: Baseline measures included years of education, age, sex, systolic blood pressure, diabetes, total cholesterol level, and smoking. Outcome was death within 10 years from CHD. The relative risk (RR) associated with less than 12 years of education compared with more than 12 years (RR 1.5; 95% confidence interval [CI], 1.2-1.8) was comparable to being male (RR 1.4; 95% CI, 1.2-1.6), smoking (RR 1.4; 95% CI, 1.1-1.6), having a total cholesterol level of greater than 280 mg/dL (RR 1.6; 95% CI, 0.9-2.7), and systolic blood pressure of 130-139 mm Hg (RR 1.6; 95% CI, 1.0-2.4). Findings were comparable for estimates of absolute risk. CONCLUSIONS: Low educational level is associated with comparable risk as established risk factors for CHD mortality. Incorporation of educational level into risk-based guidelines for treatment could potentially reduce socioeconomic disparities in CHD by lowering thresholds for treatment.     

Which patients taking SSRIs are at greatest risk of bleeding?

For patients at high risk of abnormal bleeding, consider prescribing an antidepressant with low serotonin reuptake inhibition, which may lower risk. For patients taking high-serotonin reuptake inhibition antidepressants, recommend avoidance or minimal use of nonsteroidal anti-inflammatory drugs and aspirin.     

Why are newly qualified doctors unprepared to care for patients at the end of life?

Medical Education 2011: 45 : 389–399 Context Death and dying occur in almost all areas of medicine; it is essential to equip doctors with the knowledge, skills and attitudes they need to care for patients at the end of life. Little is known about what doctors learn about end‐of‐life care while at medical school and how they learn to care for dying patients in their first year as doctors. Methods We carried out a qualitative study using face‐to‐face interviews with a purposive sample of 21 newly qualified doctors who trained in different medical schools. Results Data were analysed using a constant comparative approach. Two main groups of themes emerged. The first pertained to medical school experiences of end‐of‐life care, including: lack of exposure; a culture of ‘clerking and signs’; being kept and keeping away from dying patients; lack of examinations; variable experiences, and theoretical awareness. The second group of themes pertained to the experiences of recently qualified doctors and included: realising that patients really do die; learning by doing; the role of seniors; death and dying within the hospital culture; the role of nursing staff, and the role of the palliative care team. Conclusions Undergraduate medical education is currently failing to prepare junior doctors for their role in caring for dying patients by omitting to provide meaningful contact with these patients during medical school. This lack of exposure prevents trainee doctors from realising their own learning needs, which only become evident when they step onto the wards as doctors and are expected to care for these patients. Newly qualified doctors perceive that they receive little formal teaching about palliative or end‐of‐life care in their new role and the culture within the hospital setting does not encourage learning about this subject. They also report that they learn from ‘trial and error’ while ‘doing the job’, but that their skills and knowledge are limited and they therefore seek advice from those outside their usual medical team, mainly from nursing staff and members of palliative care teams.     

What do negative associations between potential risk factors and illness in analytical epidemiological studies of infectious disease really mean?

In epidemiological studies of infectious diseases it is not unusual to find that some potential risk factors are negatively associated with risk of illness. The mechanisms generating these associations are unclear in many cases, though one explanation is immunity due to prior exposure. We derive mathematical models for the proportion of a population who are infected with a disease and the proportion who are susceptible in any year of life when individuals are at risk of exposure through more than one route. It is shown that risk of illness declines with increasing age and that this risk declines most rapidly in those groups at increased exposure. In high exposure groups, the relative risk of illness, compared to a group with lower exposure, also declines with age, eventually becoming less than one. The threshold age at which the relative risk is less than 1, i.e., factor B becomes protective decreases with higher exposure rates. Epidemiological studies may substantially underestimate the importance of risk factors where exposure is consistent over many years.     

Why do women complain of vaginal discharge? A population survey of infectious and pyschosocial risk factors in a South Asian community

BACKGROUND: Vaginal discharge is a common complaint, particularly among women in Asia. Although presumed to be caused by reproductive tract infections (RTIs), the association between the complaint and the presence of RTIs is weak. This study aimed to investigate the risk factors of the complaint of vaginal discharge. METHODS: We conducted a community-based survey of 3000 women aged 18-50 years, randomly sampled from a population in Goa, India. Women who gave informed consent were invited to participate in a structured interview, which elicited data on the primary outcome (the experience of current abnormal vaginal discharge) and psychosocial exposures: gender adversity; symptoms of somatoform disorders; and common mental disorders (CMD). All women were required to provide vaginal and/or urine samples for diagnosis of RTIs using gold standard laboratory tests. Risk factors were analysed using logistic regression with the binary outcome of the complaint of vaginal discharge. RESULTS: Of the 2494 women (83%) who agreed to participate, 14.5% complained of having an abnormal vaginal discharge. Stress was the most common causal attribution for the complaint. The final multivariate model found that high scores for CMD (OR 2.16, 1.4-3.2) and somatoform disorders (6.23, 4.0-9.7) and the use of an intrauterine contraceptive device (1.86, 1.0-3.4) were independently associated with the complaint. Low literacy (0.54, 0.4-0.8) and age >40 years (0.29, 0.2-0.4) were associated with a reduced risk. RTI were not associated with the complaint (1.24, 0.9-1.6). CONCLUSIONS: Psychosocial factors have the strongest association with the complaint of vaginal discharge. Syndromic management algorithms need refinement so that women with complaints that are non-infectious in aetiology are offered psychosocial interventions.     

Why do men go to the doctor? Socio-demographic and lifestyle factors associated with healthcare utilisation among a cohort of Australian men

Background

Men use health services less often than women and frequently delay seeking help even if experiencing serious health problems. This may put men at higher risk for developing serious health problems which, in part, may explain men’s higher rates of some serious illnesses and shorter life span relative to women. This paper identifies factors that contribute to health care utilisation in a cohort of Australian men by exploring associations between socio-economic, health and lifestyle factors and the use of general practitioner (GP) services.

Methods

We used data from Ten to Men, the Australian Longitudinal Study on Male Health. Health care utilisation was defined in two ways: at least one GP visit in the past 12 months and having at least yearly health check-ups with a doctor. Associations between these two measures and a range of contextual socio demographic factors (education, location, marital status, country of birth, employment, financial problems etc.) as well as individual health and lifestyle factors (self-rated health, smoking, drinking, healthy weight, pain medication) were examined using logistic regression analysis. The sample included 13,763 adult men aged 18 to 55 years. Analysis was stratified by age (18 to 34 year versus 35 to 55 years).

Results

Overall, 81 % (95 % CI: 80.3–81.6) of men saw a GP for consultation in the 12 months prior to the study. The odds of visiting a GP increased with increasing age (p?<?0.01), but decreased with increasing remoteness of residence (p?<?0.01). Older men, smokers and those who rate their health as excellent were less likely to visit a GP in the last 12 months, but those on daily pain medication or with co-morbidities were more likely to have visited a GP. However, these factors were not associated with consulting a GP in the last 12 months among young men.Overall, 39 % (95 % CI: 38.3–39.9) reported having an annual health check. The odds of having an annual health check increased with increasing age (p?<?0.01), but showed no association with area of residence (p?=?0.60). Across both age groups, the odds of a regular health check increased with obesity and daily pain medication, but decreased with harmful levels of alcohol consumption.

Conclusion

The majority of men (61 %) did not engage in regular health check-up visits, representing a missed opportunity for preventative health care discussions. Lower consultation rates may translate into lost opportunities to detect and intervene with problems early and this is where men may be missing out compared to women.

     

Are patients with asthma at increased risk of coronary heart disease?

BACKGROUND: Inflammation plays a role in the pathogenesis of athero-thrombosis. Because of the chronic, inflammatory nature of asthma, we hypothesized a possible link asthma and prospective risk of coronary heart disease (CHD). METHODS: We performed a cohort study among 70 047 men and 81 573 women, 18-85 years old, enrolled in a large managed care organization in Northern California. Asthma was ascertained by self-report at baseline in 1964-1973 and/or interim hospitalization for asthma during follow-up. The primary endpoint was combined non-fatal or fatal CHD. RESULTS: After a median follow-up time of 27 years, and adjusting for age, race/ethnicity, education level, smoking status, alcohol consumption, body mass index, serum total cholesterol, white blood cell count, hypertension, diabetes, and history of occupational exposures, asthma was associated with a 1.22-fold (95% CI: 1.14, 1.31) increased hazard of CHD among women. This association was seen both in never and in ever smoking women, and in younger and older women. By contrast, asthma was not associated with CHD among men (multivariate-adjusted hazard ratio = 0.99; 95% CI: 0.93, 1.05). CONCLUSIONS: Asthma was independently associated with a modest but statistically significant increased hazard of CHD among women. Further studies are warranted to confirm or refute these preliminary epidemiological findings.     

Family communication regarding inherited high cholesterol: Why and how do patients disclose genetic risk?

Inadequate family communication concerning hereditary lipid disorders by index patients (IPs) may prevent their biological relatives from seeking testing and treatment. This lack of disclosure places the relatives at increased risk for cardiovascular disease. The present study, undertaken in the Netherlands, explored the reasons for family disclosure, and how disclosure was approached. Semi-structured interviews with 20 purposely sampled IPs revealed that they generally alerted their first-degree relatives of the genetic risk because they felt morally obliged to do so or because they were advised to do so by a health professional. However, IPs rarely alerted their more distant relatives due to insufficient risk knowledge or fear of being perceived as interfering in their relative's affairs. Furthermore, many IPs stated that they would not seek to persuade a relative to undergo testing out of respect for their autonomy. However, the findings did suggest that less direct methods were used for persuasion. An example would be stressing the severity of the condition. Consequently, the self-reported disclosures were incomplete and unbalanced. Typically, IPs provided information regarding the threat of inherited high cholesterol without furnishing information on means of coping with the risk. As IPs want and need professional support to help them disclose this information to their relatives, we suggest additional research about the ethical, practical and economic possibilities for this support.
