Unmasking a silent killer: Prevalence of diagnosed and undiagnosed diabetes mellitus among people living with HIV in rural South Africa.

OBJECTIVES: To document the prevalence of impaired glucose tolerance (IGT) and undiagnosed diabetes mellitus (DM) and to identify factors associated with undiagnosed DM in people living with HIV (PLWH). METHODS: Cross-sectional study performed at Ndlovu Medical Center, Limpopo, South Africa including PLWH aged ≥18 years. Between August and November 2017, 356 HIV-positive participants were included. Information was collected on socio-demographics, DM symptoms and risk factors for DM. IGT and DM were diagnosed using random plasma glucose and/or HbA1c. Factors associated with undiagnosed DM were assessed by comparing participants with newly diagnosed DM to participants without DM. RESULTS: IGT was diagnosed in 172 (48.3%) participants. Twenty-nine (8.1%) participants met the definition of DM, of whom 17 (58.6%) were newly diagnosed. Compared to participants without DM, participants with DM were on average 5 years older, were more likely to have a positive family history for DM, were less physically active and had higher systolic blood pressure, body mass index and waist circumference. Factors associated with undiagnosed DM included age ≥45 years (odds ratio [OR] = 3.59) and physical inactivity (OR = 3.17). CONCLUSIONS: The prevalence of IGT and DM among PLWH is high and more than half of DM cases were undiagnosed. Regular screening for DM in PLWH is recommended, especially in an ageing population with additional cardiovascular disease risk factors.

The Turkish version of the SPPIC validated among informal caregivers with a Turkish immigrant background.

BACKGROUND: This study assesses the internal consistency and known group validity of the Turkish version of the SPPIC, a measurement instrument to assess the self perceived pressure from informal care in family caregivers of people with dementia that was originally in Dutch. METHODS: The feasibility, comprehensibility and appropriateness of the Turkish SPPIC were assessed during a pilot test. Internal consistency was examined based on data from 117 family caregivers with a Turkish immigrant background by calculating Cronbach's alpha and by conducting a single-factor Confirmatory Factor Analysis (CFA). Known group validity was determined to obtain an understanding of the validity of the translated instrument, testing differences in the self-perceived pressure from informal care, depending on frequency of caregiving, living with a person with dementia and level of education. RESULTS: The pilot test showed that the translated SPPIC was considered to be feasible, comprehensible and appropriate. The internal consistency appeared to be strong (Cronbach's alpha: 0.94). The CFA indicated that the factor 'Self-perceived Pressure from Informal Care' explained varying levels of variance in the items of the SPPIC (ranging from .52 to .87). Family caregivers who provided care at least once a week and who shared a home with a person with dementia perceived a greater pressure from informal care (p = 0.007, p = 0.001). CONCLUSIONS: The Turkish translation of the SPPIC can be used in future research and practice to obtain insight into self-perceived pressure from informal care of family caregivers with Turkish immigrant backgrounds. At the same time it is recommended to conduct more research on how the measurement of self-perceived pressure from informal care in this group can be further improved.

Cultural Identity Confusion and Psychopathology: A Mixed-Methods Study Among Refugees and Asylum Seekers in the Netherlands.

Although there is ample empirical evidence that traumatic events, postmigration stress, and acculturation problems have a great impact on the mental health of refugees, so far no studies have included cultural identity after migration in the equation. This mixed-methods study conducted among Afghan and Iraqi refugee and asylum-seeker psychiatric patients aims to fill this gap. Associations between postmigration stress, symptoms of anxiety and depression disorders, and symptoms of posttraumatic stress disorder were significant. When differentiated for the two groups, associations with postmigration stress were no longer significant for Afghan patients, who were predominantly younger and more often single, lower educated, and without resident status compared with Iraqi patients. Qualitative results indicate that, in addition to psychopathology and postmigration stress, acculturation problems contribute to confusion of cultural identity. The findings suggest that reduction of postmigration stress and acculturation problems may clarify cultural identity and as such may contribute to posttraumatic recovery.

Cultural Identity Among Afghan and Iraqi Traumatized Refugees: Towards a Conceptual Framework for Mental Health Care Professionals.

Cultural identity in relation with mental health is of growing interest in the field of transcultural psychiatry. However, there is a need to clarify the concept of cultural identity in order to make it useful in clinical practice. The purpose of this study is to unravel the complexity and many layers of cultural identity, and to assess how stress and acculturation relate to (changes in) cultural identity. As part of a larger study about cultural identity, trauma, and mental health, 85 patients from Afghanistan and Iraq in treatment for trauma-related disorders were interviewed with a Brief Cultural Interview. The interviews were analysed through qualitative data analysis using the procedures of grounded theory. The analysis resulted in three domains of cultural identity: personal identity, ethnic identity and social identity. Within each domain relationships with stress and acculturation were identified. The results offer insight into the intensity of changes in cultural identity, caused by pre-and post-migration stressors and the process of acculturation. Based on the research findings recommendations are formulated to enhance the cultural competency of mental health workers.

Explanatory factors for first and second-generation non-western women's inadequate prenatal care utilisation: a prospective cohort study.

BACKGROUND: Little research into non-western women's prenatal care utilisation in industrialised western countries has taken generational differences into account. In this study we examined non-western women's prenatal care utilisation and its explanatory factors according to generational status. METHODS: Data from 3300 women participating in a prospective cohort of primary midwifery care clients (i.e. women with no complications or no increased risk for complications during pregnancy, childbirth and the puerperium who receive maternity care by autonomous midwives) in the Netherlands (the DELIVER study) was used. Gestational age at entry and the total number of prenatal visits were aggregated into an index. The extent to which potential factors explained non-western women's prenatal care utilisation was assessed by means of blockwise logistic regression analyses and percentage changes in odds ratios. RESULTS: The unadjusted odds of first and second-generation non-western women making inadequate use of prenatal care were 3.26 and 1.96 times greater than for native Dutch women. For the first generation, sociocultural factors explained 43% of inadequate prenatal care utilisation, socioeconomic factors explained 33% and demographic and pregnancy factors explained 29%. For the second generation, sociocultural factors explained 66% of inadequate prenatal care utilisation. CONCLUSION: Irrespective of generation, strategies to improve utilisation should focus on those with the following sociocultural characteristics (not speaking Dutch at home, no partner or a first-generation non-Dutch partner). For the first generation, strategies should also focus on those with the following demographic, pregnancy and socioeconomic characteristics (aged ≤ 19 or ≥ 36, unplanned pregnancies, poor obstetric histories (extra-uterine pregnancy, molar pregnancy or abortion), a low educational level, below average net household income and no supplementary insurance.

Quality of primary care for resettled refugees in the Netherlands with chronic mental and physical health problems: a cross-sectional analysis of medical records and interview data.

BACKGROUND: A high prevalence of mental and physical ill health among refugees resettled in the Netherlands has been reported. With this study we aim to assess the quality of primary healthcare for resettled refugees in the Netherlands with chronic mental and non-communicable health problems, we examined: a) general practitioners' (GP) recognition of common mental disorders (CMD) (depression and anxiety, and post-traumatic stress disorder (PTSD) symptoms); b) patients' awareness of diabetes type II (DMII) and hypertension (HT); and c) GPs' adherence to guidelines for CMD, DMII and HT. METHODS: From 172 refugees resettled in the Netherlands, interview data (2010-2011) and medical records (n = 106), were examined. Inclusion was based on medical record diagnoses for DMII and HT, and on questionnaire-based CMD measures (Hopkins Symptom Checklist for depression and anxiety; Harvard Trauma Questionnaire for PTSD). GP recognition of CMD was calculated as the number of CMD cases registered in the medical record compared with those found in interviews. Patient awareness of HT and DMII was scored as the percentage of subjects diagnosed by the GP who reported their condition during the interview. GPs' adherence to guidelines for CMD, DMII and HT was measured using established indicators. RESULTS: We identified 37 resettled refugees with CMD of which 18 (49%) had been recognised by the GP. We identified 16 refugees with DMII and 14 with HT from the medical record; 24 (80%) were aware of their condition. Thirty-five out of these 53 (66%) resettled refugees with chronic mental and non-communicable disorders received guideline-adherent treatment. CONCLUSION: This study shows that awareness in resettled refugees of GP diagnosed DMII and HT is high, whereas GP recognition of CMD and overall guideline adherence are moderate.

Factors affecting the use of prenatal care by non-western women in industrialized western countries: a systematic review.

BACKGROUND: Despite the potential of prenatal care for addressing many pregnancy complications and concurrent health problems, non-western women in industrialized western countries more often make inadequate use of prenatal care than women from the majority population do. This study aimed to give a systematic review of factors affecting non-western women's use of prenatal care (both medical care and prenatal classes) in industrialized western countries. METHODS: Eleven databases (PubMed, Embase, PsycINFO, Cochrane, Sociological Abstracts, Web of Science, Women's Studies International, MIDIRS, CINAHL, Scopus and the NIVEL catalogue) were searched for relevant peer-reviewed articles from between 1995 and July 2012. Qualitative as well as quantitative studies were included. Quality was assessed using the Mixed Methods Appraisal Tool. Factors identified were classified as impeding or facilitating, and categorized according to a conceptual framework, an elaborated version of Andersen's healthcare utilization model. RESULTS: Sixteen articles provided relevant factors that were all categorized. A number of factors (migration, culture, position in host country, social network, expertise of the care provider and personal treatment and communication) were found to include both facilitating and impeding factors for non-western women's utilization of prenatal care. The category demographic, genetic and pregnancy characteristics and the category accessibility of care only included impeding factors.Lack of knowledge of the western healthcare system and poor language proficiency were the most frequently reported impeding factors. Provision of information and care in women's native languages was the most frequently reported facilitating factor. CONCLUSION: The factors found in this review provide specific indications for identifying non-western women who are at risk of not using prenatal care adequately and for developing interventions and appropriate policy aimed at improving their prenatal care utilization.

Health literacy and pain neuroscience education in an interdisciplinary pain management programme: a qualitative study of patient perspectives.

Introduction: Pain neuroscience education is part of interdisciplinary pain management programs (IPMPs). To date, the role of health literacy on patients' understanding of pain neuroscience education has not sufficiently been examined. Objectives: Drawing on interviews with patients with diverse levels of health literacy, this article explores patient perspectives on pain neuroscience education. Methods: Purposively sampled patients from an IPMP were interviewed twice (waiting list and after 4 weeks). A directed qualitative content analysis was performed with the Integrated Conceptual Model of Health Literacy as an analytic framework. Results: Thirteen patients with chronic musculoskeletal pain were interviewed: 4 men and 9 women aged from 21 to 77 years with diverse educational and mostly low health literacy. One participant dropped out after baseline. Some participants gained access to health information actively; others relied on the expertise of their healthcare providers. Most participants did not seem to receive the information in the pain neuroscience education as intended, experienced difficulties with understanding the message, negatively appraised the information, and were not able to apply this in their daily lives. Health literacy levels likely played a role in this. Conclusions: Pain neuroscience education tailored to patients' health literacy levels, information needs, and learning strategies is needed.

Knowledge About Dementia Among Family Caregivers With a Turkish or Moroccan Immigrant Background: Development and Validation of a Dementia Knowledge Scale.

OBJECTIVE: To describe the development and validation of the Dementia Knowledge Scale (DKS) among family caregivers with a Turkish or Moroccan immigrant background. METHODS: The 11 items of the DKS, selected by professionals and people with a Turkish or Moroccan background, were translated and adapted in Turkish and Dutch. The feasibility, comprehensibility and appropriateness of the 2 language versions were examined. Subsequently, both languages were assessed among caregivers from these groups. The internal consistency of both language versions was determined by calculating Cronbach's α. The known group validity was determined by comparing mean scores between subgroups. RESULTS: Both language versions of the DKS were considered feasible, comprehensible, and appropriate. A total of 117 caregivers with a Turkish background completed the Turkish version of the DKS and 110 with a Moroccan background the Dutch version. The Turkish version showed adequate internal consistency but the Dutch version did not. No differences were found in mean scores between those with a low level of education versus those with a higher level; those who frequently provided care versus those who did so less frequently; and those who lived together with a person with dementia versus those who did not. CONCLUSIONS: The DKS is feasible, comprehensible and reliable and can be used among groups with an immigrant background. PRACTICE IMPLICATIONS: The DKS provides insight into various aspects of dementia knowledge, including knowledge about risk factors and symptoms, among caregivers with a Turkish or Moroccan background, and thereby supports the development of tailored education for these groups.

A randomized study of intensified antiretroviral treatment monitoring versus standard-of-care for prevention of drug resistance and antiretroviral treatment switch.

INTRODUCTION: Standard-of-care antiretroviral treatment (ART) monitoring in low and middle-income countries consists of annual determination of HIV-RNA viral load with confirmatory viral load testing in case of viral rebound. We evaluated an intensified monitoring strategy of three-monthly viral load testing with additional drug exposure and drug resistance testing in case of viral rebound. METHODS: We performed an open-label randomized controlled trial (RCT) at a rural South African healthcare clinic, enrolling adults already receiving or newly initiating first-line ART. During 96 weeks follow-up, intervention participants received three-monthly viral load testing and sequential point-of-care drug exposure testing and DBS-based drug resistance testing in case of rebound above 1000 copies/ml. Control participants received standard-of-care monitoring according to the WHO guidelines. RESULTS: Five hundred one participants were included, of whom 416 (83.0%) were randomized at 24 weeks. Four hundred one participants were available for intention-to-treat analysis. Viral rebound occurred in 9.0% (18/199) of intervention participants and in 11.9% (24/202) of controls ( P  = 0.445). Time to detection of rebound was 375 days [interquartile range (IQR): 348-515] in intervention participants and 360 days [IQR: 338-464] in controls [hazard ratio: 0.88 (95% confidence interval (95% CI): 0.46-1.66]; P  = 0.683]. Duration of viral rebound was 87 days [IQR: 70-110] in intervention participants and 101 days [IQR: 78-213] in controls ( P  = 0.423). In the control arm, three patients with confirmed failure were switched to second-line ART. In the intervention arm, of three patients with confirmed failure, switch could initially be avoided in two cases. CONCLUSION: Three-monthly viral load testing did not significantly reduce the duration of viraemia when compared with standard-of-care annual viral load testing, providing randomized trial evidence in support of annual viral load monitoring.

Effects of an educational intervention on health-related quality of life among family caregivers of people with dementia with a Turkish or Moroccan immigrant background: Insights from a cluster randomised controlled trial.

OBJECTIVE: Gaining understanding of the health-related quality of life (HRQL) of family caregivers of people with dementia with Turkish or Moroccan immigrant backgrounds and to examine whether an educational peer group intervention can improve HRQL. METHODS: Understanding of HRQL and associated variables was obtained by multiple linear regression analyses. The effects of the intervention on HRQL were assessed in multilevel analyses using data collected before the start (baseline), directly after the intervention (one to two weeks after baseline) and three months after the start of the intervention. The intervention (two interactive group sessions) entailed providing information about dementia and care/support options. RESULTS: At baseline (n = 319), HRQL was moderately and significantly associated with migration background, gender, self-perceived pressure from informal care and the formal and informal support received (p < .05). The intervention had a small effect on emotional wellbeing directly after the intervention (p < .05) and on perceived general health status three months after (p < .05). CONCLUSION: Culturally sensitive peer group education on dementia and care/support options can to some extent enhance HRQL among family caregivers in the short term. PRACTICE IMPLICATIONS: The intervention as described in this study is recommended for supporting family caregivers of people with dementia with Turkish or Moroccan backgrounds.

Risk factors for loss to follow-up from antiretroviral therapy programmes in low-income and middle-income countries.

INTRODUCTION: Loss to follow-up (LTFU) rates from antiretroviral treatment (ART) programmes in low- and middle-income countries (LMIC) are high, leading to poor treatment outcomes and onward transmission of HIV. Knowledge of risk factors is required to address LTFU. In this systematic review, risk factors for LTFU are identified and meta-analyses performed. METHODS: PubMed, Embase, Psycinfo and Cochrane were searched for studies that report on potential risk factors for LTFU in adults who initiated ART in LMICs. Meta-analysis was performed for risk factors evaluated by at least five studies. Pooled effect estimates and their 95% confidence intervals (95% CI) were calculated using random effect models with inverse variance weights. Risk of bias was assessed and sensitivity analyses performed. RESULTS: Eighty studies were included describing a total of 1 605 320 patients of which 87.4% from sub-Saharan Africa. The following determinants were significantly associated with an increased risk of LTFU in meta-analysis: male sex, older age, being single, unemployment, lower educational status, advanced WHO stage, low weight, worse functional status, poor adherence, nondisclosure, not receiving cotrimoxazole prophylactic therapy when indicated, receiving care at secondary level and more recent year of initiation. No association was seen for CD4 cell count, tuberculosis at baseline, regimen, and geographical setting. CONCLUSION: There are several sociodemographic, clinical, patient behaviour, treatment-related and system level risk factors for LTFU from ART programs. Knowledge of risk factors should be used to better target retention interventions and develop tools to identify high-risk patients.

A Mobile Patient-Reported Outcome Measure App With Talking Touchscreen: Usability Assessment.

BACKGROUND: In the past years, a mobile health (mHealth) app called the Dutch Talking Touch Screen Questionnaire (DTTSQ) was developed in The Netherlands. The aim of development was to enable Dutch physical therapy patients to autonomously complete a health-related questionnaire regardless of their level of literacy and digital skills. OBJECTIVE: The aim of this study was to evaluate the usability (defined as the effectiveness, efficiency, and satisfaction) of the prototype of the DTTSQ for Dutch physical therapy patients with diverse levels of experience in using mobile technology. METHODS: The qualitative Three-Step Test-Interview method, including both think-aloud and retrospective probing techniques, was used to gain insight into the usability of the DTTSQ. A total of 24 physical therapy patients were included. The interview data were analyzed using a thematic content analysis approach aimed at analyzing the accuracy and completeness with which participants completed the questionnaire (effectiveness), the time it took the participants to complete the questionnaire (efficiency), and the extent to which the participants were satisfied with the ease of use of the questionnaire (satisfaction). The problems encountered by the participants in this study were given a severity rating that was used to provide a rough estimate of the need for additional usability efforts. RESULTS: All participants within this study were very satisfied with the ease of use of the DTTSQ. Overall, 9 participants stated that the usability of the app exceeded their expectations. The group of 4 average-/high-experienced participants encountered only 1 problem in total, whereas the 11 little-experienced participants encountered an average of 2 problems per person and the 9 inexperienced participants an average of 3 problems per person. A total of 13 different kind of problems were found during this study. Of these problems, 4 need to be addressed before the DTTSQ will be released because they have the potential to negatively influence future usage of the tool. The other 9 problems were less likely to influence future usage of the tool substantially. CONCLUSIONS: The usability of the DTTSQ needs to be improved before it can be released. No problems were found with satisfaction or efficiency during the usability test. The effectiveness needs to be improved by (1) making it easier to navigate through screens without the possibility of accidentally skipping one, (2) enabling the possibility to insert an answer by tapping on the text underneath a photograph instead of just touching the photograph itself, and (3) making it easier to correct wrong answers. This study shows the importance of including less skilled participants in a usability study when striving for inclusive design and the importance of measuring not just satisfaction but also efficiency and effectiveness during such studies.

Fatty fish and supplements are the greatest modifiable contributors to the serum 25-hydroxyvitamin D concentration in a multiethnic population.

OBJECTIVE: Because vitamin D synthesis is lower in a heavily pigmented skin than in a lighter skin, the relative contribution of determinants to the vitamin D concentration might differ between ethnic groups. The aim of this study was to assess the prevalence of vitamin D deficiency and the relative contribution of vitamin D consumption and exposure to sunlight to the vitamin D concentration in a multiethnic population. DESIGN: Cross-sectional study. PATIENTS: A total of 613 adults aged 18-65 years from a random sample from general practices in the Netherlands (52 degrees N, 2003-05), stratified according to gender and ethnic group. MEASUREMENTS: Serum 25-hydroxyvitamin D [25(OH)D], PTH, ethnic group, sunlight exposure, consumption of foods and supplements rich in vitamin D. RESULTS: The prevalence (95% confidence interval) of vitamin D deficiency [serum 25(OH)D < 25 nmol/l] was higher in Turkish (41.3%; 32.5-50.1), Moroccan (36.5%; 26.9-46.1), Surinam South Asian (51.4%; 41.9-60.9), Surinam Creole (45.3%; 34.0-56.6), sub-Saharan African (19.3%; 9.1-29.5) and other adults (29.1%; 17.1-41.1) compared to the indigenous Dutch (5.9%; 1.3-10.5). Modifiable, significant determinants (standardized regression coefficients) for serum 25(OH)D concentration were: consumption of fatty fish (0.160), use of vitamin D supplements (0.142), area of uncovered skin (highest category 0.136; middle category 0.028), use of tanning bed (0.103), consumption of margarine (0.093) and preference for sun (0.089). We found no significant modification of ethnic group on the effect of sunlight determinants. CONCLUSION: Of the modifiable determinants, fatty fish and supplements are the greatest contributors to the serum 25(OH)D concentration in a multiethnic population.

Implementation of the Cultural Formulation through a newly developed Brief Cultural Interview: Pilot data from the Netherlands.

The Outline for a Cultural Formulation (OCF) has remained underutilized in clinical practice since its publication in the DSM-IV in 1994. In the Netherlands, a Cultural Interview (CI) was developed in 2002 as a tool to facilitate use of the OCF in clinical practice. The time needed to conduct the interview, however, prevented its systematic implementation within mental health institutions. This article presents the development of a shortened and adapted version, the Brief Cultural Interview (BCI), and a pilot study on the feasibility, acceptability, and utility of its implementation with refugee and asylum seeking patients in a Dutch centre for transcultural psychiatry. Results show that the brief version scores better on feasibility and acceptability, while utility for clinical practice remains similar to that of the original CI. These results support the systematic use of the OCF in psychiatric care for a culturally diverse patient population through the application of a relatively brief cultural interview. A secondary finding of the study is that patients' cultural identity was considered by clinicians to be more relevant in the treatment planning sessions than their illness explanations.

Manual therapy, physical therapy, or continued care by the general practitioner for patients with neck pain: long-term results from a pragmatic randomized clinical trial.

OBJECTIVES: The authors' goals were to compare the effectiveness of manual therapy (MT; mainly spinal mobilization), physical therapy (PT; mainly exercise therapy), and continued care by the general practitioner (GP; analgesics, counseling and education) over a period of 1 year. METHODS: One hundred eighty-three patients suffering for at least 2 weeks from nonspecific neck pain were randomized to receive a 6-week treatment strategy of MT once a week, PT twice a week, or GP care once every 2 weeks. The primary outcome measures were perceived recovery, severity of physical dysfunctioning, pain intensity, and functional disability. RESULTS: The differences between groups considered over 1 year were statistically significant (repeated measurements analyses P<0.001 to P=0.02) for all outcomes but borderline for the Neck Disability Index (P=0.06). Higher improvement scores were observed for MT for all outcomes, followed by PT and GP care. The success rate, based on perceived recovery after 13 weeks, was 72% for MT, which was significantly higher than the success rate for continued GP care (42%, P=0.001) but not significantly higher compared with PT treatment (59%, P=0.16). The difference between PT and GP approached statistical significance (P=0.06). After 1 year the success rates were 75%, 63%, and 56%, respectively, and no longer significantly different. CONCLUSIONS: Short-term results (at 7 weeks) have shown that MT speeded recovery compared with GP care and, to a lesser extent, also compared with PT. In the long-term, GP treatment and PT caught up with MT, and differences between the three treatment groups decreased and lost statistical significance at the 13-week and 52-week follow-up.

Manual therapy, physical therapy, or continued care by a general practitioner for patients with neck pain. A randomized, controlled trial.

BACKGROUND: Neck pain is a common problem, but the effectiveness of frequently applied conservative therapies has never been directly compared. OBJECTIVE: To determine the effectiveness of manual therapy, physical therapy, and continued care by a general practitioner. DESIGN: Randomized, controlled trial. SETTING: Outpatient care setting in the Netherlands. PATIENTS: 183 patients, 18 to 70 years of age, who had had nonspecific neck pain for at least 2 weeks. INTERVENTION: 6 weeks of manual therapy (specific mobilization techniques) once per week, physical therapy (exercise therapy) twice per week, or continued care by a general practitioner (analgesics, counseling, and education). MEASUREMENTS: Treatment was considered successful if the patient reported being "completely recovered" or "much improved" on an ordinal six-point scale. Physical dysfunction, pain intensity, and disability were also measured. RESULTS: At 7 weeks, the success rates were 68.3% for manual therapy, 50.8% for physical therapy, and 35.9% for continued care. Statistically significant differences in pain intensity with manual therapy compared with continued care or physical therapy ranged from 0.9 to 1.5 on a scale of 0 to 10. Disability scores also favored manual therapy, but the differences among groups were small. Manual therapy scored consistently better than the other two interventions on most outcome measures. Physical therapy scored better than continued care on some outcome measures, but the differences were not statistically significant. CONCLUSION: In daily practice, manual therapy is a favorable treatment option for patients with neck pain compared with physical therapy or continued care by a general practitioner.

Prognostic factors for neck pain in general practice.

Prognostic studies on neck pain are scarce and are typically restricted to short-term follow-up only. In this prospective cohort study, indicators of short- and long-term outcomes of neck pain were identified that can easily be measured in general practice. Patients between 18 and 70 years of age, suffering for at least 2 weeks from neck pain were recruited by 42 general practitioners (GPs). Perceived recovery, pain intensity and neck dysfunction after 7 and 52 weeks were considered as outcome measures. Indicators of prognosis were identified by means of logistic regression analyses (perceived recovery) and linear regression analyses (pain intensity and neck dysfunction). In total, 183 patients were included. After 1 year, 63% had recovered. The prognostic models showed differences between short- and long-term indicators. At the short term, besides the baseline values of the respective outcome measurements, only older age (> or =40) and concomitant low back pain and headache were associated with poor outcome. At the long term, in addition to age and concomitant low back pain, previous trauma, a long duration of neck pain, stable neck pain during the 2 weeks prior to baseline measurement, and previous neck pain predicted poor prognosis. The predictive power of the models was weak: the explained variance (R(2)) varied from 24 to 36%. Patient history and physical examination give GPs little handholds to predict the prognosis for patients with sub-acute and chronic neck pain. A few indicators of a less favourable prognosis of neck pain were identified, of which older age and concomitant low back pain was the most consistent.

The urine dipstick test useful to rule out infections. A meta-analysis of the accuracy.

BACKGROUND: Many studies have evaluated the accuracy of dipstick tests as rapid detectors of bacteriuria and urinary tract infections (UTI). The lack of an adequate explanation for the heterogeneity of the dipstick accuracy stimulates an ongoing debate. The objective of the present meta-analysis was to summarise the available evidence on the diagnostic accuracy of the urine dipstick test, taking into account various pre-defined potential sources of heterogeneity. METHODS: Literature from 1990 through 1999 was searched in Medline and Embase, and by reference tracking. Selected publications should be concerned with the diagnosis of bacteriuria or urinary tract infections, investigate the use of dipstick tests for nitrites and/or leukocyte esterase, and present empirical data. A checklist was used to assess methodological quality. RESULTS: 70 publications were included. Accuracy of nitrites was high in pregnant women (Diagnostic Odds Ratio = 165) and elderly people (DOR = 108). Positive predictive values were >/=80% in elderly and in family medicine. Accuracy of leukocyte-esterase was high in studies in urology patients (DOR = 276). Sensitivities were highest in family medicine (86%). Negative predictive values were high in both tests in all patient groups and settings, except for in family medicine. The combination of both test results showed an important increase in sensitivity. Accuracy was high in studies in urology patients (DOR = 52), in children (DOR = 46), and if clinical information was present (DOR = 28). Sensitivity was highest in studies carried out in family medicine (90%). Predictive values of combinations of positive test results were low in all other situations. CONCLUSIONS: Overall, this review demonstrates that the urine dipstick test alone seems to be useful in all populations to exclude the presence of infection if the results of both nitrites and leukocyte-esterase are negative. Sensitivities of the combination of both tests vary between 68 and 88% in different patient groups, but positive test results have to be confirmed. Although the combination of positive test results is very sensitive in family practice, the usefulness of the dipstick test alone to rule in infection remains doubtful, even with high pre-test probabilities.
