Conceptualizing safer sex in a new era: Risk perception and decision-making process among highly sexually active men who have sex with men. PLOS GLOBAL PUBLIC HEALTH 2022; 2:e0000159. [PMID: 36962224 PMCID: PMC10022342 DOI: 10.1371/journal.pgph.0000159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 04/06/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND Men who have sex with men (MSM) are at the epicenter of the HIV epidemic. Efforts to prevent sexually transmitted infections (STIs) and HIV transmission have traditionally focused on condoms and abstinence from high risk sexual practices. Recently, additional methods such as pre-exposure prophylaxis (PrEP) and viral load sorting have been introduced. The aim of this study was to gain understanding about risk management and risk perception strategies for HIV among highly sexually active Swedish MSM with men in Berlin. METHODS Eighteen sexually active Swedish MSM who travelled to or lived in Berlin were recruited and interviewed in this study. The data were analyzed using content analysis. RESULTS AND DISCUSSION These men represent a group of knowledgeable MSM in terms of HIV. They acknowledged that having sex with men in Berlin was linked to high sexual risk taking due to the higher prevalence of HIV/STIs than in Sweden, but reported that they nevertheless did not alter their risk management strategies. The analysis resulted in a conceptual model of risk assessment that allows for a deeper understanding of the complexity of the risk reduction decision-making process. Three ontological perceptions of risk were identified: accepting, minimizing and rejecting risk. Seven practiced risk reduction methods were described. Some informants applied their preferred method or set of methods to all settings and partners, while others faced complex decision-making processes. CONCLUSION HIV is integrated into the core of MSM's sexuality, independently of how they ontologically related to the idea of risk. A constant navigation between pleasure, risk and safety, alongside having to relate to risk created a complex process. Efforts were made to remove HIV from their lives by rejecting the idea of risk, and thereby reject the idea of the homosexual body being a possible vessel for a virus and an epidemic.

Sex, drugs and techno - a qualitative study on finding the balance between risk, safety and pleasure among men who have sex with men engaging in recreational and sexualised drug use. BMC Public Health 2021; 21:863. [PMID: 33952247 PMCID: PMC8097859 DOI: 10.1186/s12889-021-10906-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Accepted: 04/23/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Recreational and sexual drug use among men who have sex with men may result in increased risk of poor health. The aim of this study was to better understand drug use and harm reduction techniques among Swedish men who have sex with men traveling to Berlin in order to improve the health of this population and inform public health strategies. METHODS A qualitative study based on semi-structured interviews with 15 Swedish men aged 23-44 with experience of drug use were recruited through network sampling. Interviews were conducted in Stockholm and Berlin and analysed using content analysis. The interview guide included questions on drug use, context, health and safety. RESULTS The participants engaged in drug use in both settings and in various contexts. Participants saw themselves as capable of finding a balance between pleasure, safety and risk with the aim to maximize positive effects while minimizing negative ones. The different risks of drug use were known, and participants relied on knowledge, harm reduction strategies and self-defined rules of intake to stay safe and healthy in a broad sense, both short term (i.e. during each session) and long term. Choice of drug and, frequency of intake, multi-use, risk of overdose, risk of HIV, purpose and context of use, how often, etc. were all part of the overall strategy. Knowledge of these methods was spread within the community and on-line rather than from counsellors or other health care providers. However, it did not always translate perfectly into practice and some had experienced overdoses and problematic use. CONCLUSIONS The findings of this study point to the need for increased adoption of harm reduction techniques in this population focusing on mitigating harm and prevention of risk of problematic use or starting injection drugs. Existing traditional services require adaptations to become more accessible and acceptable to sub-groups of drug users, including low-threshold services providing non-judgemental, evidence-based information. This will require funding of alternative providers such as STI/HIV clinics, among others, and health care providers to increase adoption of prevention strategies, specifically pre-exposure prophylaxis for HIV.

Abstract
PURPOSE The purpose of this study was to explore the perceptions and experiences of sex among Swedish Men who have Sex with Men (MSM) in Berlin. BACKGROUND MSM are disproportionally affected by HIV.Berlin is also a key destination when looking into where Swedish MSM sero-convert, while travelling. METHOD A qualitative study with semi-structured interviews using open-ended questions with participants recruited through network sampling. Data were analysed with content analysis. PARTICIPANTS 15 Swedish cis-men (as in non-transgender) who have sex with men aged 25-44 years, who travelled to or were living in Berlin. To be included in the study, the participants had to be cis-MSM, Swedish citizens, spending time in Berlin and having sex in both settings. RESULTS For a majority of the participants, sex was the main reason for going to Berlin but cultural aspects like art and the techno scene were also important. Berlin was perceived as a sex-oriented city providing venues where respondents did not have to care about reputation and status and where social and sexual spaces co-existed side by side. This in sharp contrast to Sweden, which represented a limiting environment both in culture and what was available culturally and sexually. CONCLUSION The men interviewed experienced multiple partners and had a broad sexual repertoire both abroad and at home. However, the behaviour was amplified in Berlin. The men did not alter their safer sex practice depending on if they had sex in Sweden or Berlin. The high mobility and vulnerability for HIV/sexually transmitted infection (STI) among these men highlights the need of increased access to antiretroviral treatment, pre-exposure prophylaxis for HIV and low-threshold HIV/STI testing services in Europe.

“Please Don’t Send Us Spam!” A Participative, Theory-Based Methodology for Developing an mHealth Intervention. JMIR Mhealth Uhealth 2016; 4:e100. [PMID: 27535589 PMCID: PMC5007380 DOI: 10.2196/mhealth.6041] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 07/17/2016] [Accepted: 07/31/2016] [Indexed: 11/24/2022] Open
Abstract
Background Mobile health solutions have the potential of reducing burdens on health systems and empowering patients with important information. However, there is a lack of theory-based mHealth interventions. Objective The purpose of our study was to develop a participative, theory-based, mobile phone, audio messaging intervention attractive to recently circumcised men at voluntary medical male circumcision (VMMC) clinics in the Cape Town area in South Africa. We aimed to shift some of the tasks related to postoperative counselling on wound management and goal setting on safe sex. We place an emphasis on describing the full method of message generation to allow for replication. Methods We developed an mHealth intervention using a staggered qualitative methodology: (1) focus group discussions with 52 recently circumcised men and their partners to develop initial voice messages they felt were relevant and appropriate, (2) thematic analysis and expert consultation to select the final messages for pilot testing, and (3) cognitive interviews with 12 recent VMMC patients to judge message comprehension and rank the messages. Message content and phasing were guided by the theory of planned behavior and the health action process approach. Results Patients and their partners came up with 245 messages they thought would help men during the wound-healing period. Thematic analysis revealed 42 different themes. Expert review and cognitive interviews with more patients resulted in 42 messages with a clear division in terms of needs and expectations between the initial wound-healing recovery phase (weeks 1–3) and the adjustment phase (weeks 4–6). Discussions with patients also revealed potential barriers to voice messaging, such as lack of technical knowledge of mobile phones and concerns about the invasive nature of the intervention. Patients’ own suggested messages confirmed Ajzen’s theory of planned behavior that if a health promotion intervention can build trust and be relevant to the recipient’s needs in the first contacts, then the same recipients will perceive subsequent motivational messages more favorably. The health action process approach was also a useful tool for guiding the phasing of the messages. Participants were more positive and salutogenic than public health experts. Conclusions The system showed how a process of consultation can work with a set of potential recipients of an mHealth service to ensure that their needs are included. Classic behavioral theories can and should be used to design modern mHealth interventions. We also believe that patients are the best source of messaging, ensuring that messages are culturally relevant and interesting to the recipient.

What interventions are effective on reducing inequalities in maternal and child health in low- and middle-income settings? A systematic review. BMC Public Health 2014; 14:634. [PMID: 24952656 PMCID: PMC4083351 DOI: 10.1186/1471-2458-14-634] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2013] [Accepted: 06/13/2014] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND The deadline for achieving Millennium Development Goals 4 and 5 is approaching, but inequalities between disadvantaged and other populations is a significant barrier for progress towards achieving these goals. This systematic review aims to collect evidence about the differential effects of interventions on different sociodemographic groups in order to identify interventions that were effective in reducing maternal or child health inequalities. METHODS We searched the PubMed, EMBASE and other relevant databases. The reference lists of included reviews were also screened to find more eligible studies. We included experimental or observational studies that assessed the effects of interventions on maternal and child health, but only studies that report quantitative inequality outcomes were finally included for analysis. RESULTS 22 articles about the effectiveness of interventions on equity in maternal and child health were finally included. These studies covered five kinds of interventions: immunization campaigns, nutrition supplement programs, health care provision improvement interventions, demand side interventions, and mixed interventions. The outcome indicators covered all MDG 4 and three MDG 5 outcomes. None of the included studies looked at equity in maternal mortality, adolescent birth rate and unmet need for family planning. The included studies reported inequalities based on gender, income, education level or comprehensive socioeconomic status. Stronger or moderate evidence showed that all kinds of the included interventions may be more effective in improving maternal or child health for those from disadvantaged groups. CONCLUSION Studies about the effectiveness of interventions on equity in maternal or child health are limited. The limited evidence showed that the interventions that were effective in reducing inequity included the improvement of health care delivery by outreach methods, using human resources in local areas or provided at the community level nearest to residents and the provision of financial or knowledge support to demand side.

Risk perceptions of STIs/HIV and sexual risk behaviours among sexually experienced adolescents in the northern part of Lao PDR. BMC Public Health 2013; 13:1126. [PMID: 24304698 PMCID: PMC3890592 DOI: 10.1186/1471-2458-13-1126] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2013] [Accepted: 11/26/2013] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Young people in Laos are more vulnerable to STIs/HIV due to their sexual risk behaviours, low perceptions of risk and their socio-cultural environments. Perceived risk of contracting STIs/HIV is crucial for the assessment of their risk regarding their actual sexual risk behaviors. Thus, the objective of this paper is to explore perceptions of risk related to STIs/HIV and identify factors associated with this perceived risk among adolescents. METHODS This was a cross sectional study of sexually experienced adolescents aged 14 to 19 years old in the Luangnamtha province. The multistage sampling techniques were used for selecting 1008 adolescents aged 14-19 years old. Of these, 483 respondents reported having had sexual experience was selected for analysis. Univariate and Logistic regression were performed. RESULT Six per cent of respondents reported ever having had anal sex. Slightly less than two thirds initiated their first sexual intercourse before age 15. Two thirds of the sexually experienced males reported two or more sexual partners during their lifetime with the mean 3.1+3.65 while only twelve per cent of girls reported this cumulative number of partners. Slightly more than half (57.6%) regarded themselves to have no risk at all with 17.2 per cent considered themselves to have low risk. Respondents had poor knowledge on STIs/HIV. Factors associated with risk perception of getting STIs were: being male, high level of knowledge about STIs and having had symptoms of STIs in last six months. Perceived risk of getting HIV was significantly associated with being male, having more knowledge about STIs and HIV. CONCLUSION Adolescents in this study engaged in sexual risk behaviours, but they have low perception of risk getting STI/HIV. Socio-demographic factors, knowledge of STIs/HIV, and the level of exposure to STIs were the main determinants of the risk perception of STIs/HIV. Our finding supports the need to target adolescents in Luangnamtha province for HIV prevention intervention by addressing inaccurate perception of risk and increasing their knowledge on STIs/HIV.

Targeted interventions for improved equity in maternal and child health in low- and middle-income settings: a systematic review and meta-analysis. PLoS One 2013; 8:e66453. [PMID: 23840474 PMCID: PMC3688766 DOI: 10.1371/journal.pone.0066453] [Citation(s) in RCA: 42] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2012] [Accepted: 05/04/2013] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Targeted interventions to improve maternal and child health is suggested as a feasible and sometimes even necessary strategy to reduce inequity. The objective of this systematic review was to gather the evidence of the effectiveness of targeted interventions to improve equity in MDG 4 and 5 outcomes. METHODS AND FINDINGS We identified primary studies in all languages by searching nine health and social databases, including grey literature and dissertations. Studies evaluating the effect of an intervention tailored to address a structural determinant of inequity in maternal and child health were included. Thus general interventions targeting disadvantaged populations were excluded. Outcome measures were limited to indicators proposed for Millennium Development Goals 4 and 5. We identified 18 articles, whereof 15 evaluated various incentive programs, two evaluated a targeted policy intervention, and only one study evaluated an intervention addressing a cultural custom. Meta-analyses of the effectiveness of incentives programs showed a pooled effect size of RR 1.66 (95% CI 1.43-1.93) for antenatal care attendance (four studies with 2,476 participants) and RR 2.37 (95% CI 1.38-4.07) for health facility delivery (five studies with 25,625 participants). Meta-analyses were not performed for any of the other outcomes due to scarcity of studies. CONCLUSIONS The targeted interventions aiming to improve maternal and child health are mainly limited to addressing economic disparities through various incentive schemes like conditional cash transfers and voucher schemes. This is a feasible strategy to reduce inequity based on income. More innovative action-oriented research is needed to speed up progress in maternal and child survival among the most disadvantaged populations through interventions targeting the underlying structural determinants of inequity.

Disadvantaged populations in maternal health in China who and why? Glob Health Action 2013; 6:19542. [PMID: 23561030 PMCID: PMC3617641 DOI: 10.3402/gha.v6i0.19542] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2012] [Revised: 01/24/2013] [Accepted: 02/12/2013] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND China has made impressive progress towards the Millennium Development Goal (MDG) for maternal and reproductive health, but ensuring that progress reaches all segments of the population remains a challenge for policy makers. The aim of this review is to map disadvantaged populations in terms of maternal health in China, and to explain the causes of these inequities to promote policy action. METHODS We searched PUBMED, Popline, Proquest and WanFang and included primary studies conducted in mainland China. Experts were also contacted to identify additional studies. Disadvantaged populations in terms of MDG 5 and the reasons for this disadvantage explored by authors were identified and coded based on the conceptual framework developed by the WHO Commission on the Social Determinants of Health. RESULTS In China, differences in maternal health service utilization and the maternal mortality ratio among different income groups, and among regions with different socio-economic development still exist, although these differences are narrowing. Groups with low levels of education and ethnic minorities utilize maternal health care less frequently and experience higher maternal mortality, although we could not determine whether these differences have changed in the last decade. Rural-to-urban migrants use maternal health care and contraception to a lower extent than permanent residents of cities, and differential maternal mortality shows a widening trend among these groups. Gender inequity also contributes to the disadvantaged position of women. Intermediary factors that explain these inequities include material circumstances such as long distances to health facilities for women living in remote areas, behavioral factors such as traditional beliefs that result in reduced care seeking among ethnic minorities, and health system determinants such as out-of-pocket payments posing financial barriers for the poor. CONCLUSIONS Inequity in maternal health continues to be an issue worthy of greater programmatic and monitoring efforts in China.

Inequity in India: the case of maternal and reproductive health. Glob Health Action 2013; 6:19145. [PMID: 23561028 PMCID: PMC3617912 DOI: 10.3402/gha.v6i0.19145] [Citation(s) in RCA: 67] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2012] [Revised: 01/15/2013] [Accepted: 01/15/2013] [Indexed: 11/18/2022] Open
Abstract
Background Millennium Development Goal (MDG) 5 is focused on reducing maternal mortality and achieving universal access to reproductive health care. India has made extensive efforts to achieve MDG 5 and in some regions much progress has been achieved. Progress has been uneven and inequitable however, and many women still lack access to maternal and reproductive health care. Objective In this review, a framework developed by the Commission on Social Determinants of Health (CSDH) is used to categorize and explain determinants of inequity in maternal and reproductive health in India. Design A review of peer-reviewed, published literature was conducted using the electronic databases PubMed and Popline. The search was performed using a carefully developed list of search terms designed to capture published papers from India on: 1) maternal and reproductive health, and 2) equity, including disadvantaged populations. A matrix was developed to sort the relevant information, which was extracted and categorized based on the CSDH framework. In this way, the main sources of inequity in maternal and reproductive health in India and their inter-relationships were determined. Results Five main structural determinants emerged from the analysis as important in understanding equity in India: economic status, gender, education, social status (registered caste or tribe), and age (adolescents). These five determinants were found to be closely interrelated, a feature which was reflected in the literature. Conclusion In India, economic status, gender, and social status are all closely interrelated when influencing use of and access to maternal and reproductive health care. Appropriate attention should be given to how these social determinants interplay in generating and sustaining inequity when designing policies and programs to reach equitable progress toward improved maternal and reproductive health.

Bringing evidence to policy to achieve health-related MDGs for all: justification and design of the EPI-4 project in China, India, Indonesia, and Vietnam. Glob Health Action 2013; 6:19650. [PMID: 23490302 PMCID: PMC3597775 DOI: 10.3402/gha.v6i0.19650] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2012] [Accepted: 02/10/2013] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND The Millennium Development Goals (MDGs) are monitored using national-level statistics, which have shown substantial improvements in many countries. These statistics may be misleading, however, and may divert resources from disadvantaged populations within the same countries that are showing progress. The purpose of this article is to set out the relevance and design of the "Evidence for Policy and Implementation project (EPI-4)". EPI-4 aims to contribute to the reduction of inequities in the achievement of health-related MDGs in China, India, Indonesia and Vietnam through the promotion of research-informed policymaking. METHODS Using a framework provided by the Commission on the Social Determinants of Health (CSDH), we compare national-level MDG targets and results, as well as their social and structural determinants, in China, India, Indonesia and Vietnam. RESULTS To understand country-level MDG achievements it is useful to analyze their social and structural determinants. This analysis is not sufficient, however, to understand within-country inequities. Specialized analyses are required for this purpose, as is discussion and debate of the results with policymakers, which is the aim of the EPI-4 project. CONCLUSION Reducing health inequities requires sophisticated analyses to identify disadvantaged populations within and between countries, and to determine evidence-based solutions that will make a difference. The EPI-4 project hopes to contribute to this goal.

Inequity in maternal health care service utilization in Gujarat: analyses of district-level health survey data. Glob Health Action 2013; 6:1-9. [PMID: 23469890 PMCID: PMC3591509 DOI: 10.3402/gha.v6i0.19652] [Citation(s) in RCA: 47] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2012] [Revised: 02/04/2013] [Accepted: 02/10/2013] [Indexed: 11/14/2022] Open
Abstract
Background Two decades after the launch of the Safe Motherhood campaign, India still accounts for at least a quarter of maternal death globally. Gujarat is one of the most economically developed states of India, but progress in the social sector has not been commensurate with economic growth. The purpose of this study was to use district-level data to gain a better understanding of equity in access to maternal health care and to draw the attention of the policy planers to monitor equity in maternal care. Methods Secondary data analyses were performed among 7,534 ever-married women who delivered since January 2004 in the District Level Household and Facility Survey (DLHS-3) carried out during 2007–2008 in Gujarat, India. Based on the conceptual framework designed by the Commission on the Social Determinants of Health, associations were assessed between three outcomes – Institutional delivery, antenatal care (ANC), and use of modern contraception – and selected intermediary and structural determinants of health using multiple logistic regression. Results Inequities in maternal health care utilization persist in Gujarat. Structural determinants like caste group, wealth, and education were all significantly associated with access to the minimum three antenatal care visits, institutional deliveries, and use of any modern method of contraceptive. There is a significant relationship between being poor and access to less utilization of ANC services independent of caste category or residence. Discussion and conclusions Poverty is the most important determinant of non-use of maternal health services in Gujarat. In addition, social position (i.e. caste) has a strong independent effect on maternal health service use. More focused and targeted efforts towards these disadvantaged groups needs to be taken at policy level in order to achieve targets and goals laid out as per the MDGs. In particular, the Government of Gujarat should invest more in basic education and infrastructural development to begin to remove the structural causes of non-use of maternal health services.

Ethnic minority health in Vietnam: a review exposing horizontal inequity. Glob Health Action 2013; 6:1-19.

Abstract
BACKGROUND Equity in health is a pressing concern and reaching disadvantaged populations is necessary to close the inequity gap. To date, the discourse has predominately focussed on reaching the poor. At the same time and in addition to wealth, other structural determinants that influence health outcomes exist, one of which is ethnicity. Inequities based on group belongings are recognised as 'horizontal', as opposed to the more commonly used notion of 'vertical' inequity based on individual characteristics. OBJECTIVE The aim of the present review is to highlight ethnicity as a source of horizontal inequity in health and to expose mechanisms that cause and maintain this inequity in Vietnam. DESIGN Through a systematic search of available academic and grey literature, 49 publications were selected for review. Information was extracted on: a) quantitative measures of health inequities based on ethnicity and b) qualitative descriptions explaining potential reasons for ethnicity-based health inequities. RESULTS Five main areas were identified: health-care-seeking and utilization, maternal and child health, nutrition, infectious diseases, and oral health and hygiene. Evidence suggests the presence of severe health inequity in health along ethnic lines in all these areas. Research evidence also offers explanations derived from both external and internal group dynamics to this inequity. It is reported that government policies and programs appear to be lacking in culturally adaptation and sensitivity, and examples of bad attitudes and discrimination from health staff toward minority persons were identified. In addition, traditions and patriarchal structures within ethnic minority groups were seen to contribute to the maintenance of harmful health behaviors within these groups. CONCLUSION Better understandings of the scope and pathways of horizontal inequities are required to address ethnic inequities in health. Awareness of ethnicity as a determinant of health, not only as a covariate of poverty or living area, needs to be improved, and research needs to be designed with this in mind.

'Health is wealth and wealth is health'--perceptions of health and ill-health among female sex workers in Savannakhet, Laos. Glob Health Action 2013; 6:1-8. [PMID: 23336614 PMCID: PMC3536938 DOI: 10.3402/gha.v6i0.19080] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2012] [Revised: 11/09/2012] [Accepted: 12/05/2012] [Indexed: 12/05/2022] Open
Abstract
Background Female sex workers (FSWs) are vulnerable to sexually transmitted infections (STIs) and other types of health problems and they also encounter socio-economic difficulties. Efforts to develop effective health intervention programs for FSWs have been hampered by a lack of information on why FSWs do not seek or delay seeking treatment for STIs. To further understand their reasons, our study applied a qualitative approach to explore perceptions of health and ill-health among FSWs in Savannakhet province in Laos. Methods Fifteen in-depth interviews were conducted with FSWs in Savannakhet province. Latent content analysis was used for analysis. Results Sex workers’ definitions of health and wealth are intertwined. Thus, good health was described as strongly related to wealth, and wealth was needed in order to be healthy. This is explained in two sub-themes: health is necessary for work and income and ill-health creates social and economic vulnerability. Conclusions Female sex workers’ beliefs and perceptions about health and ill-health were dominated by their economic need, which in turn was influenced by expectations and demands from their families.

Abstract
Background Female sex workers (FSWs) are vulnerable to sexually transmitted infections (STIs) and encounter socio-economic and health problems, including STIs/HIV, unintended pregnancy and complications from unsafe abortion, stigma, violence, and drug addiction. Reducing risks associated with sex work requires an understanding of the social and cultural context in which sex workers live and work. This study aimed to explore the working environment and perceived risks among FSWs in Savannakhet province in Laos. Methods Five focus group discussions (FGDs) and seven interviews were conducted with FSWs in Kaysone Phomvihan district in Laos. Latent content analysis was used to analyze the transcribed text. Results The results revealed that the FSWs were aware of risks but they also talked about benefits related to their work. The risks were grouped into six categories: STIs/HIV, unintended pregnancy, stigma, violence, being cheated, and social and economic insecurity. The reported benefits were financial security, fulfilling social obligations, and sexual pleasure. The FSWs reported using a number of strategies to reduce risks and increase benefits. Conclusions The desire to be self-sufficient and earn as much money as possible put the FSWs in disadvantaged and vulnerable situations. Fear of financial insecurity, obligations to support one’s family and the need to secure the future influenced FSWs’ decisions to have safe or unsafe sex. The FSWs were, however, not only victims. They also had some control over their lives and working environment, with most viewing their work as an easy and good way of earning money.

Causes and determinants of inequity in maternal and child health in Vietnam. BMC Public Health 2012; 12:641. [PMID: 22883138 PMCID: PMC3534083 DOI: 10.1186/1471-2458-12-641] [Citation(s) in RCA: 45] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2012] [Accepted: 08/01/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Inequities in health are a major challenge for health care planners and policymakers globally. In Vietnam, rapid societal development presents a considerable risk for disadvantaged populations to be left behind. The aim of this review is to map the known causes and determinants of inequity in maternal and child health in Vietnam in order to promote policy action. METHODS A review was performed through systematic searches of Pubmed and Proquest and manual searches of "grey literature." A thematic content analysis guided by the conceptual framework suggested by the Commission on Social Determinants of Health was performed. RESULTS More than thirty different causes and determinants of inequity in maternal and child health were identified. Some determinants worth highlighting were the influence of informal fees and the many testimonies of discrimination and negative attitudes from health staff towards women in general and ethnic minorities in particular. Research gaps were identified, such as a lack of studies investigating the influence of education on health care utilization, informal costs of care, and how psychosocial factors mediate inequity. CONCLUSIONS The evidence of corruption and discrimination as mediators of health inequity in Vietnam calls for attention and indicates a need for more structural interventions such as better governance and anti-discriminatory laws. More research is needed in order to fully understand the pathways of inequities in health in Vietnam and suggest areas for intervention for policy action to reach disadvantaged populations.

Abstract
Maternal and child mortality rates, the targets for two of the eight Millennium Development Goals, remain unacceptably high in many countries. Some countries have made significant advances in reducing deaths in pregnancy, childbirth, and childhood at the national level. However, on a sub-national basis most countries show wide disparities in health indices which are not necessarily reflected in national figures. This is a sign of inequitable access to and provision of health services. Yet there has been little attention to health equity in relation to the Millennium Development Goals. Instead, countries have focused on achieving national targets. This has led to an emphasis on utilitarian, as opposed to universalist, approaches to public health, which we discuss here. We recommend a policy of "proportionate universalism". In this approach, universal health care and a universal social policy are the ultimate goal, but in the interim actions are carried out with intensities proportionate to disadvantage. We also briefly describe an initiative that aims to promote evidence-based policy and interventions that will reduce inequity in access to maternal and child health care in China, India, Indonesia and Viet Nam.

Care seeking behaviour and barriers to accessing services for sexually transmitted infections among female sex workers in Laos: a cross-sectional study. BMC Health Serv Res 2012; 12:37. [PMID: 22333560 PMCID: PMC3347996 DOI: 10.1186/1472-6963-12-37] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2011] [Accepted: 02/14/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Prompt, correct diagnosis and treatment with health information are essential components of reproductive tract infection (RTI) and sexually transmitted infection (STI) services. This study aims to describe care seeking behaviour and barriers to accessing RTI/STI services among female sex workers (FSWs) in Laos. METHODS A cross-sectional survey using closed and open-ended questions was performed in six districts along Road 9, traversing Savannakhet province from Thailand to Vietnam. In total, 407 FSWs were interviewed. The data were analyzed and presented descriptively. Multiple logistic regression analysis was applied to assess associations between respondents' background characteristics and care seeking behaviour. RESULTS About half of the respondents (49%) were less than or equal to 19 years of age, and 50% had started or completed secondary school. Fifty-eight percent had been engaged in sex work for less than 1 year. Eighty-six percent of the respondents reported RTI/STI signs or symptoms currently or in the last 3 months but only two-thirds of those with symptoms sought treatment. Source of treatment for the last RTI/STI episode was the drop-in centre (53%) followed by a public hospital (23%), private clinic (12%), private pharmacy (9%), and herbalist (2%). The main barriers to service use were long waiting time, inconvenient location of the clinic, not knowing where to get the services needed, and negative attitudes among healthcare providers. Care seeking behaviour was associated with longer duration of sex work (OR = 2.6, 95%CI 1.52-5.36). Forty-four percent received health information from peer educators, 34% from fellow friends, 26% from a pimp, and 26% had received information from a healthcare provider during the visit. CONCLUSION There were several barriers to accessing RTI/STI services and they were related to both structural and individual factors. Innovative STI service strategies to inform FSWs about the importance of early diagnosis and treatment should be established. Continuous training for STI service providers focusing on counseling skills and awareness of the sexual health care needs for FSWs is recommended in order to minimize the barriers experienced by FSWs in this particular setting.

Abstract
Based on interviews and focus group discussions conducted in northern Laos, this study explores Akha understandings of customary first pre-pubertal sex acts, a thonh thong ('break through vagina' [BV]) for girls and yaha heu ('open foreskin' [OF]) for boys, which are thought to enable the maturing of bodies into adulthood. The study also examines the practice of a thor ta yang ('Welcome Guest') in which sexually initiated girls have sex with male visitors to Akha villages. The study found that many young women experience BV as painful and traumatic. However, since all Akha in the study 'knew' that young bodies will not mature into attractive, healthy adults if they do not perform BV and OF, attitudes were largely positive. Both men and women are at increasing risk of STIs, including HIV, since resettlement and an influx of non-Akha into the area. We conclude that Akha villagers should be included in the planning of future public health strategies that do not violate their cultural commitments and dignity but that help them resist potential exploitation and threats to their health. Such strategies might include sexual education programs and encouraging the delay of BV and OF.

Abstract
This study aimed to assess the knowledge and attitudes among health care providers (HCPs) providing sexually transmitted infection (STI) service to female sex workers (FSWs). A cross-sectional survey was performed in 6 districts along Road 9, traversing Savannakhet province from Thailand to Vietnam. In total, 244 HCPs providing STI services were interviewed. In all, 54% of respondents had no STI training despite providing STI treatment. Misperceptions of STI causes, transmission routes, and symptoms were common among respondents. Attitudes differed neither between male and female respondents nor between those who had or had not received STI training. A higher proportion of pharmacists/drug sellers (68%) had negative attitudes followed by medical doctors (59%) and nurse/midwives (55%). The proportion of herbalists with negative attitudes (53%) was less in comparison with the other professionals. To improve the quality of STI services and to enhance FSWs' access to health care services, educational improvements of HCPs' knowledge about STIs and their attitudes are needed.

Abstract
In the last decade, three randomized controlled trials in Kenya, South Africa, and Uganda have shown that medical male circumcision (MMC) reduces the sexual transmission of HIV from women to men. Objectives of this assessment were to measure acceptability of adult MMC and circumcision of children to inform policies regarding whether and how to promote MMC as an HIV prevention strategy. This mixed-method study, conducted across four Ugandan districts, included a two-stage household survey of 833 adult males and 842 adult females, focus group discussions, and a health provider survey. Respondents' acceptability of MMC was positive and substantial after being informed about the results of recent randomized trials. In uncircumcised men, between 40% and 62% across the districts would consider getting circumcised. Across the four districts between 60% and 86% of fathers and 49% and 95% of mothers were supportive of MMC for sons. Widespread support exists among men and women in this study for promoting MMC as part of Uganda's current 'ABC + ' HIV prevention strategy.

Abstract
Background Multiple health risk behaviors (HRBs) among adolescents pose a threat to their health, including HIV/AIDS. Health risk behaviors such as alcohol use, smoking, substance use, and sexual risk behaviors among youth have been shown to co-occur with each others. The objectives of this study was to estimate the prevalence of single and concurrent health risk behaviors and to explore how health risk behavior is associated with socio-demographic factors and peers' behaviors. Methods A cross sectional design was used to examine health risk behaviors of adolescents between the age 14 and 19 years living in the Luangnamtha province, Lao PDR. The study was conducted between June and August, 2008. An ordinal logistic regression model that simultaneously explored demographic factors and the influence of the behavior of peers on three categories of multiple HRBs (no risk, one risk, and two or more health risk behaviors) was performed. Results A total of 1360 respondents, 669 (49.1%) boys with mean age 16.7 ± 1.6 and 699 (50.9%) girls aged 16.1 ± 1.5 were recruited into the study. The majority reported two or fewer risk behaviors. However, multiple risk behaviors increased with age for both sexes. About 46.8% (n = 637) reported no risk, 39.3 percent (n = 535) reported one risk, 8.1 percent (n = 110) reported two risks, and 5.8 percent reported more than two health risk behaviors. The protective factors among boys were school attendance (OR = .53, CI = .33-.86), being Hmong and Yao ethnicity (OR = .48, CI-.26-.90), while being above the age of 15 (OR = 2.20, 95% CI = 1.33-3.60), Akha ethnicity (OR = 2.20, 95% CI = 1.04-4.61), peer's smoking (OR = 3.11, 95% CI = 2.1-4.6), and peer's drinking alcohol (OR = 1.88, 95% CI = 1.1-3.21) were significantly associated with the presence of multiple risk behaviors among boys. Having some education (OR = 0.17, 95% CI = 0.06-0.45), and being of Hmong and Yao ethnicity (OR = 0.38, 95% CI = 0.18-0.80) were factors that protected girls from multiple risk behaviors; while peer's drinking alcohol (OR = 2.55, 95% CI = 1.59-4.09) and peer's being sexually active (OR = 2.82, 95% CI = 1.65-4.8) were significantly associated with the presence of multiple risk behaviors among girls. Conclusion There are sex, age and ethnic differences in the concurrent health risk behaviors. The influencing factors are adolescent's education and peer influence. Interventions should focus to encourage adolescents to complete the compulsory primary education as well as help them to establish friendships and follow peers with good behavior. Risk reduction messages need to take account of diverse multiple HRBs within the specific socio-cultural and gender specific context and target vulnerable adolescents such as ethnic minorities and less educated adolescents.

Abstract
Neurotransmitter release at chemical synapses occurs when synaptic vesicles fuse to the presynaptic membrane at a specialized site termed the active zone. The depolarization-induced fusion is highly dependent on calcium ions, and, correspondingly, the transmission characteristics of synapses are thought to be influenced by the spatial arrangement of voltage-gated calcium channels with respect to vesicle release sites. Here, we review the involvement of the Drosophila Bruchpilot (BRP) protein in active zone assembly, a process that is required for the clustering of presynaptic calcium channels to ensure efficient vesicle release.

Histological evidence for the role of mechanical stress in modulating thermal denaturation of collagen. Biomech Model Mechanobiol 2005; 4:201-10.

Abstract
The hyperthermia and thermal denaturation literatures reveal a time-temperature equivalency when heating cells or connective tissues: thermal damage increases with increasing temperature (for the same duration) and increases with increasing duration (for the same temperature). Recent findings conversely suggest that increasing the mechanical loading on a tissue during heating decreases the thermal damage (for a given temperature and duration of heating). Surprisingly, however, there are few histological correlates of such damage. In this paper, we show that progressive light microscopic changes - swelling of collagen bands, thickening of collagen-rich layers, hyalinization, and loss of birefringence approximately - correlate very well with both increased heating times and decreased mechanical loading. Increased mechanical stress is thus thermally protective and should be considered in the design of clinical procedures that use heating to treat diseases or injuries.

Control of foot differentiation in Hydra: Phylogenetic footprinting indicates interaction of head, bud and foot patterning systems. Mech Dev 2005; 122:998-1007.

Abstract
Homeodomain transcription factor CnNK-2 seems to play a major role in foot formation in Hydra. Recently, we reported in vitro evidence indicating that CnNK-2 has autoregulatory features and regulates expression of the morphogenetic peptide pedibin. We proposed that CnNK-2 and pedibin synergistically orchestrate foot differentiation processes. Here, we further analyzed the regulatory network controlling foot formation in Hydra. By phylogenetic footprinting we compared the CnNK-2 5'-flanking sequence from two closely related species, Hydra vulgaris and Hydra oligactis. Unexpectedly, we detected a highly conserved binding site for HNF-3beta, a vertebrate Forkhead transcription factor, in the CnNK-2 5'-flanking region. The Hydra HNF-3beta homolog budhead is predominantly expressed in the apical region of the body column and early during budding. Budhead is absent from tissue expressing CnNK-2 and thought to be involved in determining tissue for head differentiation. By electrophoretic mobility shift assays we demonstrate an in vitro interaction between recombinant budhead protein and the interspecific conserved HNF-3beta binding motif in the CnNK-2 5'-flanking region. Our results strengthen the view of CnNK-2 as an important regulator during foot patterning processes. Furtheron, they point to budhead as a candidate for a transcriptional regulator of CnNK-2 and to an interaction of foot and head patterning processes in Hydra on the molecular level.

Abstract
OBJECTIVE To explore the reasons why men who have sex with sex workers in Kenya refuse to use condoms in order to develop potential interventions that might help to overcome these barriers. METHODS We conducted participant observations over a period of 2 months in the bars, discos, shebeens, and guesthouses of Mombasa, Kenya, where many of the sexual transactions are initiated. RESULTS Analysis of the participant observations revealed at least 50 reasons for not using a condom, which we grouped into six categories: condoms are not pleasurable, condoms are defective, condoms are harmful, condoms are unnecessary, condoms are too hard to use, and external forces prohibit using condoms. CONCLUSIONS Some of the reasons men say they do not use condoms would be difficult to affect directly. Others are the result of gaps in knowledge and have not been impacted through better communication strategies. Finally, some of the reasons for not using condoms, such as men's weaknesses, and the loss of pleasure, could possibly be addressed through the introduction of female controlled devices. However, the most important conclusion of this paper is that men who pay for sex do so because it is pleasurable and many men do not find the male condom pleasurable. Therefore, messages targeted at men who have sex with sex workers may not be 100% successful if they only emphasise the benefits of condom use as disease control.

Control of foot differentiation in Hydra: in vitro evidence that the NK-2 homeobox factor CnNK-2 autoregulates its own expression and uses pedibin as target gene. Mech Dev 2004; 121:195-204.

Abstract
The foot of the simple metazoan Hydra is a highly dynamic body region of constant tissue movement, cell proliferation, determination and differentiation. Previously, two genes have been shown to participate in the development and differentiation of this body region: homeodomain factor CnNK-2 and signal peptide pedibin [Dev. Biol. 180 (1996) 473; Development 126 (1999) 517; Development 122 (1996) 1941; Mech. Dev. 106 (2001) 37]. CnNk-2 functions as transcriptional regulator and is responsive to changes in the positional value while the secreted peptide pedibin serves as "extrinsic" positional signal. Exposure of polyps to pedibin increases the spatial domain of CnNK-2 expression towards the gastric region, indicating that positional signals are integrated at the cis-regulatory region of CnNK-2. In the present study, to elucidate the molecular basis of the interaction of CnNK-2 and pedibin, we characterized the 5' regulatory regions of both genes. Within the CnNK-2 5' upstream region, electrophoretic mobility shift assays showed that putative NK-2 binding motifs are specifically bound by both nuclear protein from Hydra foot and by recombinant CnNK-2, suggesting that CnNK-2 might autoregulate its own expression. This is the first indication for an autoregulatory circuit in Hydra. In addition, we also identified NK-2 binding sites in the cis-regulatory region of the pedibin gene, indicating that this gene is one of the targets of the transcription factor CnNK-2. On the basis of these results, we present a model for the regulatory interactions required for patterning the basal end of the single axis in Hydra which postulates that CnNK-2 together with pedibin orchestrates foot specific differentiation.

Abstract
Recent studies suggest that violence in health care environments, especially mental health care, appears to be increasing. Although there is a lack of cross-cultural studies to prove it, this increase in violence would seem to be an international phenomenon. The present study sought to compare the extent and nature of violence encountered by mental health nurses in Sweden and England. Systematic studies of violence have previously been carried out independently in both countries but this was the first attempt to compare levels of violence. Clearly defined study protocols were put in place, an operational definition of 'violence' adhered to, and random samples recruited. A specially designed questionnaire was sent to every subject (Swedish nurses n=720; English nurses n=296) enquiring about the extent of nurses' exposure to violence, the nature and severity of the violence experienced, and the effect of violence on self-esteem and job satisfaction. Significant differences were found with English nurses experiencing more violence than their Swedish counterparts. Yet support for English nurses appeared to be less good than for Swedish nurses. Reasons for the differences are discussed along with possible measures to minimise the frequency of violence against nurses and the negative effects on their work.

Abstract
We characterized the fluorescence intensity distribution within the epithelia and stroma of frozen human cervical tissues at the following excitation-emission wavelength pairs: 440, 525 nm and 365, 460 nm. The intensities at both excitation-emission wavelength pairs are significantly lower in the epithelia of severely dysplastic tissues, relative to that in normal and inflammatory tissues. Furthermore, there are small differences in (1) the epithelial intensity of severe dysplasia and mild dysplasia at 440, 525 nm and (2) the stromal intensity of inflammatory and severely dysplastic tissues at 365, 460 nm. A comparison of the ratio of intensities at 440, 525 nm and 365, 460 nm between the epithelia of each tissue type indicates that this ratio is lowest in severely dysplastic tissues. It is interesting to note that the epithelial and stromal intensities are comparable at 365, 460 nm; however, at 440, 525 nm, the epithelial intensity is more than a factor of two less that that of the stroma for all tissue types.

Abstract
BACKGROUND Tinea capitis is the most common dermatophytosis of childhood with increasing incidence. Whereas griseofulvin is considered by many as the mainstay of treatment, newer oral antifungal agents, including fluconazole, itraconazole and terbinafine have demonstrated higher efficacy, resulting in shorter treatment durations. OBJECTIVES We aimed to determine the optimum regimen for the treatment of childhood tinea capitis with itraconazole. METHODS A mycological culture outcome-dependent combination of a 28-day continuous and facultative additional 14-day courses with itraconazole was used in 42 children (20 girls; 22 boys) aged 12-140 months (mean 66) with tinea capitis due to Microsporum canis (n = 26) and Trichophyton violaceum (n = 16). The drug was given orally according to the patients' body weight (50 mg daily for < 20 kg; 100 mg daily for > or = 20 kg) over 4 weeks. Direct microscopy and fungal culture as a parameter for efficacy were repeated 2 weeks after termination of treatment. Assessment of efficacy was based on the evaluation of results from light microscopy and culture at 8 weeks after initiation of treatment, and in the case of a further positive mycological culture at 14 and 20 weeks, respectively. A positive fungal culture at these times resulted in an additional course for 2 weeks with the initially chosen itraconazole dosage. RESULTS In 34 of 42 patients a single 4-week course of itraconazole resulted in a complete mycological cure of lesions as demonstrated by light microscopy and mycological culture. Four of 42 patients had to be treated by a second itraconazole course for 2 weeks, and four children received a third course of itraconazole for 2 weeks until all lesions showed negative direct microscopy and mycological culture. No abnormal haematological or biochemical results occurred. Apart from transient, completely reversible indigestion in two children, no side-effects were observed. CONCLUSIONS A culture-based 28-day continuous therapeutic regimen plus facultative cultural outcome-dependent additional 14-day courses of a body weight-adapted dosage of itraconazole in tinea capitis due to M. canis and T. violaceum is discussed; this offers the advantage of an effective therapy with complete negative direct microscopy as well as negative cultural results, within a shorter active treatment period (cf. previous studies with continuous administration of itraconazole).

Abstract
Hematopoietic stem cells (HSC) are an important target for retroviral gene transfer. However, transduction efficiency in these HSC is extremely low compared to fibroblasts or more mature hematopoietic cells. This infection block was analyzed in the HSC line FDC-Pmix. The infection frequency with the amphotropic murine leukemia virus (MLV-A) is more than 100-fold lower in FDC-Pmix cells as compared to fibroblasts. Pseudotyping with the env of the 10A1 strain (MLV-10A1), which uses both the amphotropic receptor (Pit-2) and the receptor for gibbon ape leukemia virus (Pit-1), did not improve the infection efficiency. Vectors pseudotyped with VSV G protein were found to overcome the infection block in FDC-Pmix, confirming that the block is at the level of virus binding and possibly penetration. Accordingly, we could not detect virus binding of MLV-A or MLV-10A1 to FDC-Pmix cell lines. Northern blot analysis was performed to detect whether the defect is at the level of transcription. Surprisingly, similar levels of Pit-2 receptor transcripts were detected in all cell types. The overexpression of rat Pit-2 DNA in CHO but not in FDC-Pmix cells improved amphotropic infection frequency after introducing rat Pit-2 DNA into the cells. Taken together these results show that the inefficient infection of FDC-Pmix is due to a lack of functional receptors. Either the receptor protein is incorrectly processed in these cells or a cofactor is missing in FDC-Pmix cells that is necessary for efficient binding and/or penetration.

Abstract
BACKGROUND Mental health personnel are at high risk for mental illness, burnout and suicide. Previous studies of this group of professionals have indicated the importance of organisational factors in explaining burnout, or exhaustion, and work satisfaction. This study looks more systematically at the contribution of organisational and individual factors to work-related exhaustion and to professional fulfillment, an expanded version of job satisfaction. METHODS A cross-sectional study of 1, 051 psychiatrists and mental health nurses in the city of Stockholm was carried out by postal questionnaire with a previously validated instrument. Multiple and logistic regressions were used to identify predictors of exhaustion and professional fulfillment. RESULTS Organisational characteristics were found to be more important than individual characteristics in predicting exhaustion and professional fulfillment in mental health professionals. CONCLUSIONS The results indicate that the psychosocial work environment and well-being of mental health professionals can be improved by concentrating on organisational factors such as efficiency, personal development and goal quality.

Abstract
BACKGROUND AND OBJECTIVE Thermal denaturation of proteins is recognized as a rate process governed by the local temperature-time response. Since rate processes are exponential with temperature, laser-assisted tissue welding was performed with and without temperature feedback control (TFC) to investigate the efficacy of temperature feedback in enhancing the photothermal welding process in vivo. STUDY DESIGN/MATERIALS AND METHODS An automated system was developed for temperature feedback controlled laser irradiation. An experimental device incorporating co-aligned laser delivery and temperature detection was used to perform argon laser welded (with and without TFC) enterotomies. The weld strength and histology of laser welded and control sutured enterotomies were compared in an in vivo rat model. Animals (n = 41) were sacrificed at 1, 3, 7, and 21 days postoperatively, and the anastomotic site was removed for bursting/leaking pressure measurements and histological examination. RESULTS Laser-welded (with and without TFC) and control sutured anastomoses in surviving animals healed comparably. Some laser-welded anastomoses without TFC ruptured spontaneously (4 out of 15) leading to the animals' death within the first 24-36 hours postoperatively. None of the animals in the other groups had this problem (control suture 0/6; laser with TFC 1 leak/8). The bursting/leaking pressures of the laser welded anastomoses were not significantly different than those of the sutured controls. CONCLUSION TFC improves the quality of laser-welded rat intestinal anastomoses in vivo in the critical first postoperative 36 hours.

Abstract
BACKGROUND AND OBJECTIVE Temperature feedback control (TFC) during laser-assisted tissue welding was implemented to eliminate exponential increases in the rate of denaturation associated with rapidly increasing temperatures. This study was undertaken to investigate and compare the weld strengths and healing responses of laser welded enterotomies with and without TFC using a cw Ho:YAG laser and to examine the effects of wavelength on weld strength and histology. The Ho:YAG experimental results were compared with a similar study using cw argon ion laser irradiation. STUDY DESIGN/MATERIALS AND METHODS An automated system was developed for temperature feedback controlled laser irradiation. An experimental device incorporating co-aligned laser delivery and temperature detection was used to perform cw Ho:YAG laser-welded enterotomies (with and without TFC). The weld strength and histology of laser welded and control sutured enterotomies were compared in an in vivo rat model (Ho:YAG, n = 42; argon, n = 41). Animals were sacrificed at 1, 3, 7, and 21 days postoperatively and the anastomotic site was removed for bursting/leaking pressure measurements and histological examination. RESULTS Argon and Ho:YAG laser-welds with and without TFC and the control sutured anastomoses healed comparably, although wound abscesses were more prevalent in the Ho:YAG group leading to delay in mucosal healing. Laser-welded anastomoses without TFC were associated with more spontaneous ruptures and leaks (argon: 4/6 ruptures; Ho:YAG: 1/4 leak, 2/4 ruptures, & 1/3 stenosis) during the survival period than those with TFC (argon: 1/3 leak; Ho:YAG: 1/5 rupture). Bursting pressures of the Ho:YAG welds were weaker at 1 week than the argon welds, but by 3 weeks, laser welds and suture anastomoses were equally strong. CONCLUSION From the spontaneous failure rates encountered, it is believed that TFC improves the quality and stability of laser-assisted enterotomy closures in surviving animals. However, TFC does not provide a satisfactory method to identify completion of a weld.

Abstract
Fluorescence spectroscopy has potential to improve cervical precancer detection. The relationship between tissue biochemistry and fluorescence is poorly understood. The goal of this study was to characterize normal cervical autofluorescence, using fresh tissue short-term tissue cultures and epithelial cell suspensions. Transverse, short-term tissue cultures were prepared from 31 cervical biopsies; autofluorescence images were obtained at 380 and 460 nm excitation. Fluorescence excitation-emission matrices were measured from normal, precancerous and cancerous cervical cell suspensions. Observed fluorescence patterns contrast those reported for frozen-thawed tissue, and were placed into groups with (1) bright epithelial and weak stromal fluorescence; (2) similar epithelial and stromal fluorescence; and (3) weak epithelial and bright stromal fluorescence. The average ages of women in the groups were 30.9, 38.0 and 49.2 years. Epithelial fluorescence intensity was similar in Groups 1 and 2, but weaker in Group 3. Stromal intensity was similar in Groups 2 and 3, but weaker in Group 1. The ratio of epithelial to stromal fluorescence intensity was significantly different for all groups. EEMs of cell suspensions showed peaks consistent with tryptophan, reduced form of nicotinamide adenine dinucleotide (phosphate) and flavin adenine dinucleotide. Short-term tissue cultures represent a novel, biologically appropriate model to understand cervical autofluorescence. Our results suggest a biological basis for the increased fluorescence seen in older, postmenopausal women.

Abstract
Fourteen patients suffering from acute, exacerbated atopic eczema were screened for changes in collagen I and collagen III metabolism in serum (n = 11), urine (n = 11) and skin biopsies (n = 9) before and after medium-dose ultraviolet (UV) A1 phototherapy (15 exposures of 50 J/cm2 over a 3-week period, total dose 750 J/cm2). Mature collagen I and, to a lesser extent, mature collagen III were found to be decreased after the therapy in skin samples from the irradiated patients. As markers of collagen I degradation, the cross-links pyridoline and deoxypyridoline were analysed in urine using high-performance liquid chromatography. Both cross-links were found to be mildly increased after UVA1 phototherapy, without reaching statistical significance. As markers of de novo collagen synthesis we screened for the procollagen I-carboxyterminal peptide (PICP) and procollagen III-aminoterminal peptide (PIIINP) levels in serum and skin. The ratio of PICP to PIIINP in serum dropped significantly after the UVA1 phototherapy, suggesting a different impact of UVA1 on the two collagens. These findings were paralleled by a diminished ratio of PICP to PIIINP in tissue samples. Staining for matrix metalloproteinase 1 (MMP-1) and its specific counterpart, tissue inhibitor of MMP-1 (TIMP-1), showed slight increases for both proteins by therapeutic UVA1; this was also seen in serum for TIMP-1 but not MMP-1. In our study, high-energy UVA1 doses induced changes of the skin collagens in patients with atopic eczema which are measurable by their metabolites in serum and urine.

Abstract
Nonresponse to surveys, which seems to plague work environment studies and studies of health care personnel in particular, may pose problems of generalizability and validity. The aim of this study was to provide an estimate of nonresponse error in a self-administered survey concerning the work environment of psychiatric health care personnel. A random sample of 10% of the original survey population (N = 693) was selected to participate in a telephone follow-up of a postal survey that had a response rate of 51%. There were no differences between the responders and nonresponders to the postal survey on the exposure or outcome variables. There was no evidence of nonresponse bias in this study, although recall bias may have been a problem. In those cases in which generalizability is deemed important, it is recommended that nonresponse studies be regularly carried out when response rates are less than 100%.

Abstract
Violence against mental health service personnel is a serious workplace problem and one that appears to be increasing. This study aimed to ascertain the extent and nature of violence against mental health nurses and psychiatrists, and to identify what support, if any, they received following exposure to violence. Mental health staff working within five West Midlands Trusts in the United Kingdom were surveyed using a postal questionnaire to investigate the extent and nature of violence they encountered in their daily work. There was an overall response rate of 47%, which included a response rate for psychiatrists of 60% (n=74) and for mental health nurses of 45% (n=301). Though both groups experienced violence at work, nurses were found: to have been exposed to violence significantly more during their career; to have been a victim of violence within the previous 12 months of the survey; and to have suffered a violent incident involving physical contact. Whilst a higher proportion of nurses than psychiatrists received some support following a violent incident, a large proportion of both groups did not receive any, although most felt in need of it. The implications of this study for training and management are discussed.

Abstract
Although health care systems around the world are undergoing rapid changes, there is an absence of comparative studies of how these changes affect nurses' well-being and work life. The purpose of this study was (i) to identify and describe possible differences between the psycho-social work environments of English and Swedish mental health nurses, and (ii) to attempt to explain these differences. 1016 psychiatric nurses from Stockholm (Sweden) and Birmingham (England) responded to a postal questionnaire on their psycho-social work environment and feelings of professional fulfillment, mental energy and work-related exhaustion. The study was given ethical clearance in Stockholm and Birmingham. Results indicated that while the English nurses rated their organizational well-being more favourably, Swedish psychiatric nurses reported greater individual well-being than their counterparts. Multiple regression analyses indicated that self-esteem was important for explaining mental energy and work-related exhaustion, but less so for explaining professional fulfillment, which was predicted primarily by organizational factors. When controlling for self-esteem, which was higher amongst the Swedish nurses, the differences in professional fulfillment and mental health were no longer significant. Reasons for the differences in self-esteem and experiences of the workplace are discussed. Low response rate may have contributed to a selection bias.

Abstract
Recently, we have shown that inhibition of caspase-3-like caspases is the most effective treatment strategy to protect adult rat retinal ganglion cells from secondary death following optic nerve transection. In the present study, we localized active caspase-3 in axotomized retinal ganglion cells in vivo and demonstrated a co-localization of the active p20 fragment and TUNEL-staining in some of these cells. In line with this, we detected an enhanced cleavage and activity of caspase-3 protein in retinal tissue after lesion, while caspase-3 mRNA expression remained unchanged. These data suggest caspase-3 as an important mediator of secondary retinal ganglion cell death following axotomy in vivo.

Abstract
OBJECTIVE To determine the efficacy of a computer-controlled bipolar endotubal catheter system designed to accomplish safe, effective, and inexpensive female sterilization in preventing pregnancy in a rabbit model. DESIGN Prospective controlled study. SETTING University animal care facility. ANIMAL(S) Sixty healthy virginal female New Zealand white rabbits. INTERVENTION(S) Rabbits were assigned to the following groups: [1] endotubal radiofrequency minimal energy (95 degrees C) treatment; [2] endotubal radiofrequency maximal energy (105 degrees C) treatment; [3] endouterine radiofrequency (105 degrees C) treatment; [4] nonsurgical control; [5] laparotomy-only control; [6] endotubal radio-frequency sham control; and [7] external Kleppinger forceps bipolar cautery control. Rabbits were mated at 4 or 12 weeks after treatment. MAIN OUTCOME MEASURE(S) Pregnancy outcomes in treated animals and nontreated controls. RESULT(S) No pregnancies were observed in any of the uterine horns in which minimal or maximal energy was delivered to the fallopian tubes or uterus, although pregnancy occurred in one horn as a result of the delivery of energy below the radiofrequency minimum of 95 degrees C. The outcomes of the treatment groups were significantly different from those of the nonsurgical and sham surgical control groups. CONCLUSION(S) With adequate tissue heating, 100% sterilization efficacy was achieved with a new, computer-controlled bipolar catheter, whereas pregnancies occurred in all untreated control groups. If human studies support these results, the goal of a safe, effective means of transcervical sterilization may be realized.

Abstract
This comparative study of the perceptions of mental health nurses and psychiatrists about aspects of their work environment was undertaken in the West Midlands in England. The aim of the study was to ascertain the extent to which the environment in which mental health professionals' work impacts on their own mental and physical well-being. Seventy-four psychiatrists and 301 mental health nurses responded to a postal questionnaire. Analysis of data indicated that significant differences exist between nurses and psychiatrists in their working conditions, their physical working environment, their sources of support with a work-related problem, and the effects of their work on their own mental and physical health. The main recommendation derived from this study was to improve communication between mental health professionals and their managers by giving more structured feedback and guidance about one's work performance. This may help to alleviate the mental strain many mental health professionals experience in their work.

Abstract
Amphotropic Moloney-murine leukemia virus recombinants (Mo-AmphoV) induce a severe spongiform encephalomyelopathy in newborn mice. We show here that a coisogenic recombinant with a 10A1-MuLV host range (Mo-10A1V) also induces a neurodegenerative disease, clinically characterized by mild tremor and ataxia. Spongiform lesions are most severe in the metencephalon and mesencephalon but extend into the prosencephalon and spinal cord. Significantly, the quality of histopathology was indistinguishable between Mo-AmphoV and Mo-10A1V, probably reflecting a final common pathogenic pathway. Common receptor use thus may be an important determinant in the pathogenicity of these viruses. These results have implications for the clinical use of retroviral pseudotypes that use phosphate transporters for cell entry.

Abstract
BACKGROUND Few studies have attempted to analyse the organisational aspects of the workplace that may affect the well-being of psychiatrists and even fewer have offered insights into what a positive workplace might look like. This study provides an outline of such a workplace, with reference to individual and organisational factors. In addition, a comparison is made between two European cities to check for cultural differences. METHOD Three hundred and eighty psychiatrists from Stockholm and Birmingham responded to a previously tested questionnaire on their work environment. RESULTS Predictors of a positive workplace for psychiatrists were: high self-esteem, satisfactory support with work-related problems, lower perceived workload, positive view of leadership, low work-related exhaustion and having a sense of participation in the organisation. There were few cultural differences. CONCLUSIONS Measures should be taken to improve leadership skills for managers, to offer more support for work-related problems, and to allow psychiatrists to participate more in the organisation.
