Updating the Evidence on Functional Capacity Evaluation Methods: A Systematic Review

Objectives To synthesize the evidence on the psychometrics functional capacity evaluation (FCE) methods. Methods A systematic literature search in nine databases. The resulting articles were screened based on predefined in- and exclusion criteria. Two reviewers independently performed this screening. Included studies were appraised based on their methodological quality. Results The search resulted in 20 eligible studies about nine different FCE methods. The Baltimore Therapeutic Equipment work simulator showed a moderate predictive validity. The Ergo-Kit (EK) showed moderate variability and high inter- and intra-rater reliability. Low discriminative abilities and high convergent validity were found for the EK. Concurrent validity of the EK and the ERGOS Work Simulator was low to moderate. Moderate to high test–retest, inter- and intra-reliability was found in the Isernhagen Work-Systems (IWS) FCE. The predictive validity of the IWS was low. The physical work performance evaluation (PWPE) showed moderate test–retest reliability and moderate to high inter-rater reliability. Low internal and external responsiveness were found for the PWPE, predictive validity was high. The predictive validity of the short-form FCE was also high but need to be further examined on several psychometric properties. Low discriminative and convergent validity were found for the work disability functional assessment battery. The WorkHab showed moderate to high test–retest, inter- and intra-rater reliability. Conclusion Well-known FCE methods have been rigorously studied, but some of the research indicates weaknesses in their reliability and validity. Future research should address how these weaknesses can be overcome.     

The effectiveness of medical and vocational interventions for reducing sick leave of self‐employed workers

We investigate whether interventions by (a) medical doctors and (b) occupational specialists are effective in reducing sick leave durations among self‐employed workers. Therefore, we exploit unique administrative data comprising all sick leave claims by self‐employed workers insured with a major Dutch private insurer between January 2009 and March 2014. We estimate a multivariate duration model dealing with nonrandom selection into the two intervention types by controlling for observable and unobservable claimant characteristics. We find adverse treatment effects for both interventions, irrespective of whether they are started early or (middle) late in the sickness spell.

Hydraulic Bench Testing of the TruCATHTM/TruCCOMTM Continuous Cardiac Output Monitor

The aim of this study was to test the truCATH^TM/ truCOMMS^TM continuous cardiac output catheter/monitor in a computer-controlled pulsatile mock loop system. The pulmonary artery catheter is equipped with two thermistors and a heating coil which maintains a 2°C temperature difference between the thermistors. The required electrical power is assumed to be an indicator of cardiac output. The catheter was tested under a variety of loading conditions including changes in heart rate (60, 75, 90, 120 beats/mm), filling pressures (0–15 mmHg), ventricular driving pressures (22–135 mmHg), and pulmonary resistance (0.08–1.47 mmHgs/mL) in random combinations, generating flows of 1.5–10 L/min. Fluid temperature was varied between 32 and 42°C. Our data demonstrate a good linear relation between the electrical power output of the TruCATH^TM/TruCOMMS^TM catheter and the actual flow as measured volumetrically. The system appeared to be sensitive to fluid temperature changes, but dimensionless analysis with Womersley and Reynolds numbers revealed that it is a direct consequence of the temperature-dependent water viscosity. We conclude that the TruCATH^TM/TruCOMMS^TM is a potentially useful clinical tool but the absolute correspondence between the catheter output and the patient's actual cardiac output remains to be assessed.     

Age-related differences in vastus lateralis fascicle behavior during fast accelerative leg-extension movements

Leg-extensor rate of power development (RPD) decreases during aging. This study aimed to identify the underlying mechanism of the age-related decline in RPD during a fast acceleration in terms of in vivo vastus lateralis (VL) fascicle shortening behavior. Thirty-nine men aged between 25 and 69 years performed three maximal isokinetic leg-extensor tests with a fixed initial acceleration of 45° knee extension in 150 ms until 340°/s knee angular velocity. RPD, VL activity, and ultrasound images were recorded to assess (relative) fascicle shortening and mean shortening velocity for the phases of electromechanical delay, pretension, and acceleration. Our findings show that fascicle shortening and mean shortening velocity during a fast action increase with aging (0.002 per year, P = .035 and 0.005 s⁻¹ per year, P = .097, respectively), mainly due to a higher amount of shortening in the phase of electromechanical delay. The ratio of VL fascicle length over upper leg length at rest showed a negative correlation (r = −.46, P = .004) with RPD/body mass, while pennation angle at rest showed a trend toward a positive correlation (r = .28, P = .089). To conclude, our findings indicate that the ability to reach high VL fascicle shortening velocities in vivo is not reduced in older men while performing preprogrammed fast accelerations. The greater amount of fascicle shortening in old age is probably the result of age-related differences in the tendinous properties of the muscle-tendon complex, forcing the fascicles to shorten more in order to transmit the muscle force to the segment.     

Could you have said no? A mixed‐methods investigation of consent to HIV tests in four African countries

Introduction

Although most studies report high frequencies of consent to HIV tests, critics argue that clients are subject to pressure, that acceptors later indicate they could not have refused, and that provider-initiated HIV testing raises serious ethical issues. We examine the meaning of consent and why clients think they could not have refused.

Methods

Clients in Burkina Faso, Kenya, Malawi and Uganda were asked about consenting to HIV tests, whether they thought they could have refused and why. Textual responses were analyzed using qualitative and statistical methods.

Results

Among 926 respondents, 77% reported they could not have said no, but in fact, 60% actively consented to test, 24% had no objection and only 7% tested without consent. There were few significant associations between categories of consent and their covariates.

Conclusions

Retrospectively asking clients if they could have refused to test for HIV overestimates coercion. Triangulating qualitative and quantitative data suggests a considerable degree of agency.     

Maternal use of antidepressant or anxiolytic medication during pregnancy and childhood neurodevelopmental outcomes: a systematic review

Antidepressant and anxiolytic medications are widely prescribed and used by pregnant women for acute and maintenance therapy. These drugs are able to pass the placental barrier, and may potentially influence fetal and brain development. It is possible that exposure to prenatal antidepressants or anxiolytic medication may disturb neurotransmitter systems in the brain and have long-lasting consequences on neurodevelopment in the offspring. As all medication during pregnancy may pose a certain risk to the developing fetus, the potential benefits of the medication must be weighed against the risks for both mother and her unborn child. Therefore, information to guide patients and physicians to make a well-balanced decision for the appropriate treatment during pregnancy is needed. In this systematic review, an overview of maternal use of antidepressant or anxiolytic medication during pregnancy and childhood neurodevelopmental outcomes is provided. Some studies indicate a relation between prenatal exposure to antidepressants and adverse neurodevelopmental outcomes such as delayed motor development/motor control, social difficulties, internalizing problems and autism, but cannot rule out confounding by indication. Overall, the results of the observational studies have been inconsistent, which makes translation of the findings into clinical recommendations difficult. More well-designed observational studies and also randomized controlled trials (e.g., maintenance treatment vs. cessation) are needed to move forward and provide a comprehensive evaluation of the risks and benefits of antidepressant and anxiolytic use during pregnancy.     

Educational paper: Parenting a child with a disfiguring condition—how (well) do parents adapt?

Studies indicate serious levels of stress among parents of children with a medical condition. Moreover, adaptation seems to be a specific challenge for parents of children with a disfiguring condition because of the visible nature of the condition. In the present overview, we performed a literature search in PubMed, Embase, and PsycINFO to identify both qualitative and quantitative studies concerning psychological distress among parents of children with a disfiguring condition. Two of the authors critically appraised the retrieved citations. A total of 1,459 publications were identified, of which 21 qualitative and 22 quantitative studies met our inclusion criteria. Most qualitative studies infer that the birth of a child with a disfiguring condition starts an adaptation process in which parents experience a range of negative emotions and have concerns related to the visible nature of the condition. The results of quantitative studies are mixed and contradictory, and together suggest that some, but not all parents of a child with a disfiguring condition experience stress. Methodological limitations of the quantitative studies and potential stressors are discussed, and recommendations for future research are made. Conclusion The present overview neither shows that the existing literature is conclusive about the perceived strain among the parents of children with a disfiguring condition nor does it provide evidence for a relationship between visibility and parental strain.
