Practices in primary health care oriented toward the harmful consumption of drugs

Objective To analyze the practices of primary care focused on the harmful consumption of drugs. Method This is a qualitative study, developed with a dialectical-critical approach. Data collection was carried out through semi-structured interviews with 10 employees of a basic health unit (UBS). Results The demands are not accepted, and if they go beyond the barriers shaped by the historical absence of health care practices for drug users and moralistic and preconceived ideologies, they are not reinterpreted as health needs; practices that meet these demands and go beyond the barriers are poor; the functionalist approach, which explains drug use as a disease and considers drug users as deviants, supports the few existing practices. Conclusion primary health care is mistakenly focused on addiction; it lacks structural elements of the production process in health and internal dynamics of the working processes that would foster the development of collective practices.

Intimate partner violence against pregnant women: the environment according to Levine's nursing theory

Abstract OBJECTIVE Analyzing the elements that compose the environment of pregnant women who have experienced intimate partner violence in the light of Levine's Nursing Theory. METHOD A qualitative, descriptive study conducted from September to January 2012, with nine pregnant women in a Municipal Health Center in Rio de Janeiro. The interviews were semi-structured and individual. The theoretical framework was based on Levine's Nursing Theory. RESULTS Thematic analysis evidenced the elements that composed the external environment, such as violence perpetrated by intimate partners before and during pregnancy, violence in childhood and adolescence, alcohol consumption and drug use by the partner, unemployment, low education and economic dependency, which affected health and posed risks to the pregnancy. CONCLUSION Violence perpetrated by an intimate partner was the main external factor that influenced the internal environment with repercussions on health. This theory represents a tool in nursing care which will aid in detecting cases and the fight against violence.

The vulnerability of Brazilian female prisoners to HIV infection

The purpose of the present study was to determine the vulnerability of women in prison to HIV infection. The study was carried out from August to October 2000 in a São Paulo State Penitentiary, where 299 female prisoners were serving time. We interviewed and obtained a blood sample from 290 females who agreed to enter the study. Sera were tested for the presence of antibodies to HIV, hepatitis C virus (HCV) and syphilis and the odds ratio (OR) was calculated for variables related to HIV positivity on the basis of a questionnaire. The overall prevalence data were: 13.9% for HIV (37 of 267), 22.8% for syphilis (66 of 290), and 16.2% for HCV (47 of 290). Sexual partnership variables were significantly related to HIV infection. These included HIV-positive partners (OR = 7.36, P = 0.0001), casual partners (OR = 8.96, P = 0.009), injectable drug user partners (OR = 4.7, P = 0.0001), and history of sexually transmitted disease (OR = 2.07, P = 0.05). In addition, a relationship was detected between HIV infection and drug use (OR = 2.48, P = 0.04) and injectable drug use (OR = 4.2, P = 0.002). Even women with only one partner presented a significant OR for HIV infection (OR = 2.57, P = 0.009), reflecting their vulnerability due to their trust in their partner, who did not use a condom. Although the use of injectable substances is associated with HIV infection, our results point to sexual behavior as the most important component of HIV transmission in the female prisoner population.

Preliminary data on the prevalence of psychiatric disorders in Brazilian male and female juvenile delinquents

The aim of the present investigation was to study the prevalence of psychiatric disorders in a sample of delinquent adolescents of both genders and to compare the prevalence between genders. A total of 116 adolescents (99 males and 17 females) aged 12 to 19 on parole in the State of Rio de Janeiro were interviewed using the screening interview based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime (KSADS-PL). Data were collected between May 2002 and January 2003. Of 373 male and 58 female adolescents present in May 2002 in the largest institution that gives assistance to adolescents on parole in the city of Rio de Janeiro, 119 subjects were assessed (three of them refused to participate). Their average age was 16.5 years with no difference between genders. The screening interview was positive for psychopathology for most of the sample, with the frequencies of the suggested more prevalent psychiatric disorders being 54% for attention-deficit/hyperactivity disorder, 77% for conduct disorder, 41% for oppositional defiant disorder, 57% for anxiety disorder 57, 60% for depressive disorder 60, 63% for illicit drug abuse, and 58% for regular alcohol use. Internalizing disorders (depressive disorders, anxiety disorders and phobias) were more prevalent in the female subsample. There was no significant difference in the prevalence of illicit drug abuse between genders. There were more male than female adolescents on parole and failure to comply with the sentence was significantly more frequent in females. The high prevalence of psychopathology suggested by this study indicates the need for psychiatric treatment as part of the prevention of juvenile delinquency or as part of the sentence. However, treatment had never been available for 93% of the sample in this study.

There is no difference in hepatic fibrosis rates of patients infected with hepatitis C virus and those co-infected with HIV

Some studies have suggested that human immunodeficiency virus (HIV) infection modifies the natural history of hepatitis C virus (HCV) infection, accelerating the progression of fibrosis and the development of cirrhosis. Our objective was to evaluate the fibrosis progression rate (FPR) in HCV/HIV-co-infected patients, and to identify factors that may influence it. HCV-mono-infected and HCV/HIV-co-infected patients with a known date of HCV infection (transfusion or injection drug use) and a liver biopsy were included. The FPR was defined as the ratio between the fibrosis stage (Metavir score) and the estimated length of infection in years and the result was reported as fibrosis units per year. The factors studied were gender, age at infection, consumption of alcohol, aminotransferase levels, histological activity grade, HCV genotype and viral load, CD4 cell count, HIV viral load, and the use of antiretroviral therapy. Sixty-five HCV-infected (group 1) and 53 HCV/HIV-co-infected (group 2) patients were evaluated over a period of 19 months. The mean FPR of groups 1 and 2 was 0.086 ± 0.074 and 0.109 ± 0.098 fibrosis units per year, respectively (P = 0.276). There was a correlation between length of HCV infection and stage of fibrosis in both groups. The age at infection, the aspartate aminotransferase level (r = 0.36) and the inflammatory activity grade were correlated with the FPR (P < 0.001). No difference in FPR was found between HCV-mono-infected and HCV/HIV-co-infected patients.

Hypomagnesemia is a risk factor for nonrecovery of renal function and mortality in AIDS patients with acute kidney injury

The objective of the present study was to determine the prevalence of electrolyte disturbances in AIDS patients developing acute kidney injury in the hospital setting, as well as to determine whether such disturbances constitute a risk factor for nephrotoxic and ischemic injury. A prospective, observational cohort study was carried out. Hospitalized AIDS patients were evaluated for age; gender; coinfection with hepatitis; diabetes mellitus; hypertension; time since HIV seroconversion; CD4 count; HIV viral load; proteinuria; serum levels of creatinine, urea, sodium, potassium and magnesium; antiretroviral use; nephrotoxic drug use; sepsis; intensive care unit (ICU) admission, and the need for dialysis. Each of these characteristics was correlated with the development of acute kidney injury, with recovery of renal function and with survival. Fifty-four patients developed acute kidney injury: 72% were males, 59% had been HIV-infected for >5 years, 72% had CD4 counts <200 cells/mm³, 87% developed electrolyte disturbances, 33% recovered renal function, and 56% survived. ICU admission, dialysis, sepsis and hypomagnesemia were all significantly associated with nonrecovery of renal function and with mortality. Nonrecovery of renal function was significantly associated with hypomagnesemia, as was mortality in the multivariate analysis. The risks for nonrecovery of renal function and for death were 6.94 and 6.92 times greater, respectively, for patients with hypomagnesemia. In hospitalized AIDS patients, hypomagnesemia is a risk factor for nonrecovery of renal function and for in-hospital mortality. To determine whether hypomagnesemia is a determinant or simply a marker of critical illness, further studies involving magnesium supplementation in AIDS patients are warranted.
