RADIAL head arthroplasty: does ligaments repair influence outcomes? A minimum two years follow-up radiographic multi-center study.

PURPOSE: The current indication for comminuted radial head fractures is radial head arthroplasty (RHA). The main purpose of this study was to investigate any statistical differences in terms of prosthesis revision or removal and radiographic degenerative changes by comparing patients who underwent RHA and ligaments repair to those who underwent only RHA implant at minimum two years follow-up. The secondary aim was to delineate a trend profile of RHA implants. METHODS: All patients who underwent RHA surgery for traumatic pathology between January 2012 and December 2017 were eligible. Two researchers independently and retrospectively reviewed the patients' charts and collected the following data: type of prosthesis, associated surgical procedures and revision surgery. They also looked for any radiographic sign of prosthesis loosening, overstuffing, capitellar osteopenia, heterotopic ossification and degenerative changes. No clinical evaluation was performed. RESULTS: In 6 years, 124 RHA were implanted (74 female, 50 male, mean age 56). The main diagnoses were: terrible triad, trans-olecranon fracture and isolated radial head fracture. It was found no significant statistical difference between the 2 groups; nevertheless, the cohort of patients that underwent ligaments repair had a lower revision rate in comparison with the other. Suture of the annular ligament seems to be critical. The overall revision rate was 10.5%. CONCLUSION: This multi-center study found no evidence that ligaments repair, as an associated surgical procedure, improves RHA longevity, except for annular ligament. Nevertheless, it seems to prevent degenerative changes at midterm follow-up.

Grammont versus lateralizing reverse shoulder arthroplasty for proximal humerus fracture: functional and radiographic outcomes.

PURPOSE: The aim of this study is to retrospectively compare clinical and radiographic outcomes of patients treated with non-lateralizing reverse shoulder arthroplasty (RSA) and with humeral lateralizing RSA after proximal humerus fracture (PHF). METHODS: In total, 32 patients (8 men and 24 women), with a mean age of 77.4 (67-92), have been reevaluated (follow-up of 14.3 months) and divided into Grammont group (G-group-16 patients, 2 men and 14 women, mean age 82.3) and lateralizing group (L-group-16 patients, 4 men and 12 women, mean age 72.5). The dominant side was affected in 21 patients. Pain, Constant-Murley score (CMS), range of motion accurately measured with inertial sensors (SHoWlder, NCSLab®) and complications. Anatomic tuberosity healing, signs of loosening or mobilization of the implants and scapular notching (according to Sirveaux classification) have been measured on standard X-ray series (antero-posterior view in neutral, external and internal rotation; axillary view; outlet view). RESULTS: Similar CMS was recorded between the two groups (G-group: 61/100; L-group: 64/100). G-group had higher forward flexion (128° vs. 112°) and abduction (126° vs. 114°), L-group had higher external rotation in abduction (35° vs. 41°); similar internal rotation (sacrum) and rotation with elbow in adduction were measured (12° vs. 19°). No statistically significant differences emerged. Anatomic healing of the tuberosity was higher in G-group (87.5% vs. 50%); low-grade scapular notching was higher in L-group (18.25% grade 1-2 vs. 0). Anatomic healed tuberosity guaranteed highly statistically significant improved functional outcomes. No revisions of the implant were performed. CONCLUSIONS: RSA can be considered a valid solution for the treatment of PHF in elderly low-demanding population. Cuff conditions should be investigated before surgery for the indication of the adequate model.

Modeling and reinforcement to combat HIV: the MARCH approach to behavior change.

Theory and research suggest that behavioral interventions to prevent HIV/AIDS may be most effective when they are personalized and affectively compelling, when they provide models of desired behaviors, and when they are linked to social and cultural narratives. Effective strategies must also take into account the opportunities and obstacles present in the local environment. The Modeling and Reinforcement to Combat HIV (MARCH) projects combine key aspects of individual behavior change with efforts to change social norms. There are 2 main components to the program: entertainment as a vehicle for education (longrunning serialized dramas on radio or television portray role models evolving toward the adoption of positive behaviors) and interpersonal reinforcement at the community level (support from friends, family members, and others can help people initiate behavior changes; support through changes in social norms is necessary for behavioral effects to be sustained over time). Both media and interpersonal intervention activities should be linked to existing resources in the community and, wherever possible, provide increased access to preventive services, supplies, and other supporting elements.

Reproductive and contraceptive attitudes as predictors of condom use among women in an HIV prevention intervention.

This study prospectively evaluates the effect of childbearing motivation and contraceptive attitudes on consistency of condom use among at-risk women enrolled in an HIV prevention intervention. Women (age 15-40, 85% African-American) were recruited from homeless shelters, drug treatment facilities, and public housing developments and assigned to standard or enhanced intervention conditions. Among the eligible study group of nonsterilized women with a main partner (n = 312), 24.4% wanted to have a baby at baseline; 43.5% believed their partner wanted them to have a baby. Women who reported a desire for a baby, compared to all others, were less likely to be at a higher level of condom consistency six months later (OR = 0.66; .48-.90). Women who perceived partner support for contraceptive use showed a higher level of condom consistency (OR = 1.20; 1.03-1.41) at 6-month follow-up. Many women in this study wanted to have a baby and this desire interfered with subsequent consistency of condom use. We also found that condom use increased toward consistency of use among women whose partner supported contraceptive use. HIV prevention interventions should include screening for reproductive motivation, so that prevention messages can be tailored to the realities of women's lives. Women who want a baby can be educated about disease prevention in the context of pregnancy planning and linked with appropriate services. Women who want to avoid childbearing can be given messages that emphasize the contraceptive benefits of condom use and that help strengthen partner support.

Long-term effectiveness of a peer-based intervention to promote condom and contraceptive use among HIV-positive and at-risk women.

OBJECTIVE: The authors used data from a larger study to evaluate the long-term effects of a peer advocate intervention on condom and contraceptive use among HIV-infected women and women at high risk for HIV infection. METHODS: HIV-infected women in one study and women at high risk for HIV infection in a second study were selected from the Women and Infants Demonstration Project and assigned to a standard or an enhanced HIV prevention treatment group. The enhanced intervention included support groups and one-on-one contacts with peer advocates tailored to clients' needs. The authors interviewed women at baseline and at 6-, 12- and 18-months, and measured changes in consistency of condom and contraceptive use and in self-efficacy and perceived advantages and disadvantages of condom and contraceptive use. RESULTS: Of HIV-infected women, the enhanced group had improved consistency in condom use, increased perceived advantages of condom use, and increased level of self-efficacy compared with the standard group. Of women at risk, the enhanced intervention group at six months maintained consistent condom use with a main partner and perceived more benefit of condom use compared with the standard group. These differences diminished at 12 months. CONCLUSIONS: The enhanced intervention was generally effective in the HIV+ study. In the at-risk study, however, intervention effects were minimal and short-lived. Factors related to the theory, intervention design, and sample characteristics help explain these differences.

Talking about hysterectomy: the experiences of women from four cultural groups.

As part of the Ethnicity, Needs, and Decisions of Women (ENDOW) project, in-depth qualitative interviews and focus groups were conducted at four sites, Alabama, New Mexico, South Carolina, and Texas. In South Carolina and Alabama, African American and white women were interviewed. In Texas, African American, Caucasian, and Hispanic women were interviewed, and in New Mexico, focus groups with Caucasian, Hispanic, and Navajo women were conducted. The Texas site also conducted focus groups with lesbian women. Data were collected on women's experiences with and attitude toward menopause, hysterectomy, and hormone replacement therapy (HRT). Information also was gathered on women's concerns and what experiences they have had or expect to have with healthcare providers and what they perceive their friends', families', and sexual partners' attitudes are toward hysterectomy. Numerous commonalties of experience existed across racial and ethnic groups. Overall, the women who participated believed that doctors do not take the time to explain issues related to menopause, hysterectomy, and HRT. Most of the women who have had a hysterectomy were satisfied with the outcome of surgery, as painful symptoms were relieved. There are also several interesting differences among the groups. Decision-making patterns differed among the ethnic groups, as did experience with healthcare providers. Many women in the focus groups expressed mistrust of or negative opinions of healthcare providers. African Americans expressed mistrust of their motives for recommending surgery, as did several of the Caucasian, non-Hispanic women. Most of the Hispanic participants respected and trusted their providers. All groups said they would seek additional medical opinions if they could afford to do so.

Distribution along a stages-of-behavioral-change continuum for condom and contraceptive use among women accessed in different settings. Prevention of HIV in Women and Infants Demonstration Projects.

The numbers of women of childbearing age in the US with HIV and AIDS from heterosexual transmission continues to rise. Behavioral interventions remain the best means of preventing transmission of HIV. Program planners often implement interventions to promote behavioral change in a wide range of settings such as family planning or sexually transmitted disease clinics, drug treatment facilities, or medical facilities that serve high risk and HIV positive women. Women recruited in different types of settings, however, may differ with respect to their experience with, attitudes toward, and willingness to use condoms and contraception. Such differences should be considered when tailoring interventions to the populations being served. We examined the readiness to use condoms and contraception among 3784 women in four cities recruited in three different types of settings: community, facilities not targeted to HIV positive women and medical facilities for HIV positive populations. Readiness to use condoms or contraception was measured using The Transtheoretical Model of Change. Women reported being in different stages along the continuum of condom and contraceptive use in the three settings. A greater proportion of women in the HIV-facility, 45%, had used condoms consistently for the previous 6 months compared to women in the other two settings (12% and 11%). Similarly, variation across settings was seen for contemplation of consistent contraceptive use to prevent unintended pregnancies. The variability in the distribution of condom and contraceptive use across settings underscores the importance of assessing the readiness for the behavior change and designing interventions that meet the specific needs of the populations being served.

Psychosocial factors associated with the stages of change for condom use among women at risk for HIV and STDs: implications for intervention development.

This study examined the prevalence of consistent condom use among inner-city women at risk for HIV, measured the distribution of these women across the stages of change for condom use, determined psychosocial factors associated with the stages, and suggested intervention strategies based on the results. The 5-city sample of women aged 15-34 years consisted predominantly of African Americans. Only 18% reported consistent condom use with main partners and 45% with other partners. Logistic regressions compared women in each stage of change with those in higher stages for each partner type. Results indicated that women who practice or intend to practice consistent condom use were more likely to talk with others about condoms, acknowledge the advantages of condoms, have higher self-efficacy for condom use, and indicate that people important to them favored condom use. Intervention approaches are suggested for women in different stages of change for condom use.

PIP: This cross-sectional study examines the prevalence of consistent condom use among inner-city women at risk for HIV and measured the distribution of these women across the stages of change for condom use. It further determined the psychosocial factors that could be used by program planners to design interventions for these women in different stages of change. The study sample was composed of women aged 15-34 years who were mostly African-Americans (79%). In the results, only 18% reported consistent condom use with main partners and 45% with other partners. The results further indicated that women who practice or intend to practice consistent condom use were more likely to talk with others about condoms, acknowledge the advantages of condoms, have higher self-efficacy for condom use, and state that people important to them favored condom use.

Behavioral science activities at the Centers for Disease Control and Prevention. A selected overview of exemplary programs.

Behavioral research and surveillance activities are conducted across the Centers for Disease Control and Prevention (CDC). This article highlights activities in 4 program areas: violence against women, tuberculosis elimination, HIV prevention, and occupational health. The unique constraints and opportunities of each organization and program focus have shaped the way research has developed in each of these areas. Behavioral scientists also face many common challenges at CDC. Despite the difficulties of integrating behavioral research into an institution that historically has focused on biomedical and epidemiological research, behavioral scientists have made important contributions to public health. Many opportunities remain for psychologists to translate theory and operationalize constructs for use in solving important public health problems.

Sources of AIDS information among low-risk and at-risk populations in five U.S. cities. AIDS Community Demonstration Projects.

Sources of HIV information were examined for 4,329 residents in five inner-city neighborhoods. Half of the respondents were female; 58% were African American, 21% Hispanic, and 21% White. Forty-nine percent of participants reported one or more practices contributing to HIV risk: injection drug use (35%), sexual contact with an injection drug user (31%), prostitution (27%), or for men, anal sex with a male partner (5% of males). Most had received HIV information in the prior three months through mass or small media sources (78%), and 47% had spoken with someone about HIV. Television was the most frequently mentioned media source (48% of all respondents), while friends and family were the most frequently cited interpersonal source (20%). Exposure to specific mass and small media sources was related to gender, ethnicity, and risk status. Women and individuals at-risk of HIV infection were most likely to have talked with someone about HIV in the past three months. African Americans, however, were less likely to have discussed HIV. Differences associated with gender, ethnicity, and risk status were also observed for interpersonal information sources. Implications for future HIV education efforts are discussed.

Using formative research to lay the foundation for community level HIV prevention efforts: an example from the AIDS Community Demonstration Projects.

The AIDS Community Demonstration Projects provided community-level HIV prevention interventions to historically hard-to-reach groups at high risk for HIV infection. The projects operated under a common research protocol which encompassed formative research, intervention delivery, process evaluation, and outcome evaluation. A formative research process specifically focusing on intervention development was devised to assist project staff in identifying, prioritizing, accessing, and understanding the intervention target groups. This process was central to the creation of interventions that were acceptable and unique to the target populations. Intended to be rapid, the process took 6 months to complete. Drawn from the disciplines of anthropology, community psychology, sociology, and public health, the formative research process followed distinct steps which included (a) defining the populations at high-risk for HIV; (b) gathering information about these populations through interviews with persons who were outside of, but who had contact with, the target groups (such as staff from the health department and alcohol and drug treatment facilities, as well as persons who interacted in an informal manner with the target groups, such as clerks in neighborhood grocery stores and bartenders); (c) interviewing people with access to the target populations (gatekeepers), and conducting observations in areas where these high-risk groups were reported to gather (from previous interviews); (d) interviewing members of these groups at high risk for HIV infection or transmission; and (e) systematically integrating information throughout the process. Semistructured interview schedules were used for all data collection in this process. This standardized systematic method yielded valuable information about the focal groups in each demonstration project site. The method, if adopted by others, would assist community intervention specialists in developing interventions that are culturally appropriate and meaningful to their respective target populations.

Measuring the adoption of consistent use of condoms using the stages of change model. AIDS Community Demonstration Projects.

The stages of behavior change model has been used to understand a variety of health behaviors. Since consistent condom use has been promoted as a risk-reduction behavior for prevention of human immunodeficiency virus (HIV) infection, an algorithm for staging the adoption of consistent condom use during vaginal sex was empirically developed using three considerations: HIV prevention efficacy, analogy with work on staging other health-related behaviors, and condom use data from groups at high risk for HIV infection. This algorithm suggests that the adoption of consistent condom use among persons at high risk can be meaningfully measured with the model. However, variations in the algorithm details affect both the interpretation of stages and apportionment of persons across stages.

Paraprofessional delivery of a theory based HIV prevention counseling intervention for women.

This report describes a mid-course process evaluation of an HIV risk-reduction counseling intervention delivered by specially trained peer paraprofessionals. One of the key questions addressed is whether paraprofessionals can successfully implement a theory-based counseling intervention. The project, known as Project CARES, is a 5-year demonstration research project to prevent HIV infection and unplanned pregnancies in women at risk for HIV infection and transmission who were recruited from homeless shelters, drug treatment facilities, and hospital-based service settings for HIV-infected women. Project CARES uses an enhanced counseling intervention based on the Transtheoretical Model, also known as the Stages of Change model, to promote condom and other contraceptive use for women who wish to avoid pregnancy, condom use for disease prevention, and reproductive health service use. Peer paraprofessionals, called advocates, provide stage-tailored counseling using a structured manual which guides them in the selection of specific counseling activities appropriate to a woman's level of readiness to change her behavior. Data from process evaluation forms completed by advocates in Philadelphia and Baltimore document that the delivery of the intervention is consistent with the theoretical model upon which it was based. Paraprofessionals can become skilled in the delivery of a stage-based counseling intervention in health and social service settings. The use of paraprofessionals in HIV prevention service delivery may be a cost-effective way to enhance and extend services for women.

Validation of measures of condom and other contraceptive use among women at high risk for HIV infection and unintended pregnancy.

This study assessed the applicability of the transtheoretical model of behavior change (J.O. Prochaska & C.C. DiClemente, 1983, 1984) to the measurement of contraceptive use among 296 women at high risk for HIV infection and transmission. Structural equation modeling suggested that a measure of general contraceptive use could be used to assess use of oral contraceptives and hormonal implants but that measurement of condom use required separate assessments for main and other partners. Self-efficacy (SE) and decisional balance scales were internally consistent for general contraceptive use, for condom use with main partners, and for condom use with other partners. Consistent with research on other health behaviors, SE scores rose significantly across stages, from precontemplation to maintenance, and a shift in decisional balance was observed for 2 of 3 behaviors. This measurement strategy may enhance the ability to evaluate prevention programs for women at risk.

PIP: The authors assessed the applicability of the transtheoretical model of behavior change to the measurement of contraceptive use among 296 women at high risk for HIV infection and transmission. Data were collected in 1992 from the US Centers for Disease Control's multisite Prevention of HIV in Women and Infants Demonstration Project. In the transtheoretical model, which originated from smoking cessation and psychotherapy research, behavior change is a gradual, continuous, dynamic process in which people move through a sequence of five stages. Structural equation modeling suggested that a measure of general contraceptive use could be used to assess the use of oral contraceptives and hormonal implants, but that measurement of condom use requires separate assessments for main and other partners. Self-efficacy (SE) and decisional balance scales were internally consistent for general contraceptive use, for condom use with main partners, and for condom use with other partners. SE scores rose significantly across stages, from recontemplation to maintenance, and a shift in decisional balance was observed for two of three behaviors. This measurement strategy may enhance the ability to evaluate prevention programs for women at risk.

Relationship between contraceptive method choice and beliefs about HIV and pregnancy prevention.

BACKGROUND AND OBJECTIVES: The goal of this study was to examine the relationship between contraceptive method choice and perceptions of HIV and pregnancy risk among women at risk of HIV infection and transmission. STUDY DESIGN: Women who were infected with HIV or who were at high risk of infection were administered a questionnaire assessing sexual and drug-related HIV risk behaviors and beliefs, STD and pregnancy history, and intentions, beliefs and behaviors regarding pregnancy, childbearing and contraception. RESULTS: Among women who reported using a contraceptive method every time they had intercourse, 43% used condoms only, 22% used birth control pills only, and 11% used both. Only 58% of consistent condom users believed they were very unlikely to become infected with HIV in the next year. Controlling for risk factor differences, pill-only users were less likely to believe themselves at risk of HIV infection, and more confident in their ability to prevent HIV infection, compared with condom-only users. CONCLUSION: Results suggest that women's beliefs about the effectiveness of a method for pregnancy prevention may generalize to beliefs about the efficacy of the method for disease prevention.

PIP: This study was conducted to explore the relationship between contraceptive method choice and perceptions of HIV and pregnancy risk among women at risk of HIV infection and transmission. To that end, questionnaires on sexual and drug-related HIV risk behaviors and beliefs, sexually transmitted disease (STD) and pregnancy history, and intentions, beliefs, and behaviors on pregnancy, childbearing, and contraception were given to 924 women with HIV or at high risk of infection from 4 cities. Of women who reported using a contraceptive method during every episode of sexual intercourse, 43% used condoms only, 22% used birth control pills only, and 11% used both. Only 58% of consistent condom users, however, believed that they were very unlikely to become infected with HIV in the next year. Moreover, compared to condom-only users, pill-only users were less likely to believe themselves at risk of HIV infection and were more confident in their ability to prevent HIV infection. These findings suggest that when women believe that a contraceptive method will effectively prevent pregnancy, they may also generalize that the method will effectively prevent the sexual transmission of disease. For women who believe thus and rely upon the contraceptive pill to protect themselves against both unwanted pregnancy and STDs, urgent sex and health educational interventions are called for. It should be made clear to women what the contraceptive pill does to protect against STDs and that condoms, when used properly and consistently, reduce the risk of both unwanted pregnancy and STD transmission.

An evaluation of sexual behaviour change using statistical and cognitive models. The AIDS Community Demonstration Projects.

We evaluate sexual behaviour change among homosexual men enrolled in the cohorts in four AIDS Community Demonstration Projects. Behaviour change is classified following the stages of behaviour change model and described using a Markov model. Predictors of behaviour change are identified and evaluated using logit models for correlated data. Sexual behaviour change within the cohort could be modelled as a first-order Markov process. In addition, predictors suggested by models of health behaviour were correlated with particular patterns of sexual behaviour change. Our evaluation revealed a variety of patterns of sexual behaviour change in the cohorts and suggests multi-faceted interventions for promotion of behaviour change.

Evidence for the effects of HIV antibody counseling and testing on risk behaviors.

OBJECTIVE: To review published abstracts, journal articles, and presentations for evidence of the effects of human immunodeficiency virus (HIV) antibody counseling and testing on risk behaviors. Studies reviewed focused on homosexual men, intravenous drug users in treatment programs, pregnant women, and other heterosexuals. DATA SOURCES: Peer-reviewed journals (January 1986 through July 1990) and published abstracts and oral presentations from the second (1986) through the sixth (1990) International Conferences on AIDS. STUDY SELECTION: We identified 66 studies that included data on the behavioral effects of HIV antibody counseling and testing. By consensus of the authors, 16 of these were excluded because of small sample size or inadequate study design. DATA EXTRACTION: Studies were assessed by the authors according to methodological strength (sample selection, inclusion of appropriate comparison groups, and inclusion of statistical tests of significance). DATA SYNTHESIS: All longitudinal studies of homosexual men reported reductions in risky behavior among both tested and untested men, and a few reported greater decreases among seropositive men than among seronegative men and those untested or unaware of their serostatus. For intravenous drug users in treatment, we found reductions in intravenous drug use and sexual risk behaviors regardless of counseling and testing experience. We found little evidence for the impact of counseling and testing on pregnancy and/or pregnancy termination rates for either seropositive or seronegative high-risk women. We noted substantial risk reduction among heterosexual couples with one infected partner. Findings among other heterosexuals at increased risk were scanty and mixed. CONCLUSIONS: Further studies should specifically address the behavioral consequences of counseling and testing in various settings.
