Implementing Precision Psychiatry: A Systematic Review of Individualized Prediction Models for Clinical Practice.

Abstract: BACKGROUND The impact of precision psychiatry for clinical practice has not been systematically appraised. This study aims to provide a comprehensive review of validated prediction models to estimate the individual risk of being affected with a condition (diagnostic), developing outcomes (prognostic), or responding to treatments (predictive) in mental disorders. METHODS PRISMA/RIGHT/CHARMS-compliant systematic review of the Web of Science, Cochrane Central Register of Reviews, and Ovid/PsycINFO databases from inception until July 21, 2019 (PROSPERO CRD42019155713) to identify diagnostic/prognostic/predictive prediction studies that reported individualized estimates in psychiatry and that were internally or externally validated or implemented. Random effect meta-regression analyses addressed the impact of several factors on the accuracy of prediction models. FINDINGS Literature search identified 584 prediction modeling studies, of which 89 were included. 10.4% of the total studies included prediction models internally validated (n = 61), 4.6% models externally validated (n = 27), and 0.2% (n = 1) models considered for implementation. Across validated prediction modeling studies (n = 88), 18.2% were diagnostic, 68.2% prognostic, and 13.6% predictive. The most frequently investigated condition was psychosis (36.4%), and the most frequently employed predictors clinical (69.5%). Unimodal compared to multimodal models (β = .29, P = .03) and diagnostic compared to prognostic (β = .84, p < .0001) and predictive (β = .87, P = .002) models were associated with increased accuracy. INTERPRETATION To date, several validated prediction models are available to support the diagnosis and prognosis of psychiatric conditions, in particular, psychosis, or to predict treatment response. Advancements of knowledge are limited by the lack of implementation research in real-world clinical practice. A new generation of implementation research is required to address this translational gap.

Use of Ecological Momentary Assessment (EMA) in Non-Suicidal Self-Injury (NSSI): A systematic review.

Abstract: Conceptualization and assessment of non-suicidal self-injury (NSSI) has evolved substantially in recent years. In both cross-sectional and longitudinal studies, NSSI and its related variables have traditionally been assessed retrospectively, leading to less precise studies of the mechanisms involved in the maintenance, cessation, or aggravation of this behavior. Ecological momentary assessment (EMA) enables real-time collection of patient states, which can be very useful in the study of the mechanisms implied in this behavior. This systematic review aims to elucidate the current status of EMA use in NSSI investigation. An exhaustive search in PubMed and PsycINFO was conducted up to September 2017. All papers included were focused on the study of NSSI using EMA. Studies with methodological diversity were included, which were afterwards organized according to main topic of studies. There were no ineligibility criteria based on age or diagnosis. Twenty-three papers were studied, the majority of which are short-term studies focused on the study of affect dynamics and the emotion-regulation function of NSSI. Implications of these results and recommendations for future research are discussed.

Ultrasound joint inflammation in rheumatoid arthritis in clinical remission: how many and which joints should be assessed?

Abstract: Objective To investigate the sensitivity for detecting subclinical synovitis of different reduced joint ultrasound (US) assessment models as compared with a comprehensive US assessment in rheumatoid arthritis (RA) patients in clinical remission. Methods Sixty-seven RA patients (50 women, 17 men) in clinical remission as judged by their consultant rheumatologist and treated with methotrexate were prospectively recruited. Patients were evaluated for disease activity according to the Disease Activity Score in 28 joints (DAS28) and the Simplified Disease Activity Index (SDAI) by the same investigator. Each patient underwent a 44-joint B-mode and power Doppler (PD) assessment by a rheumatologist blinded to the clinical and laboratory data. B-mode synovial hypertrophy (SH) and synovial PD signal were scored from 0–3 at each joint. Global indices for SH and PD signal were calculated for the 44-joint and different joint combination models for each patient. Results SH was detected in 87.8% of patients with a DAS28 <2.6 and in 81.8% of patients with an SDAI <3.3. Synovial PD signal was detected in 46.3% of patients with a DAS28 <2.6 and in 36.4% of patients with an SDAI <3.3. Wrist, second through fifth metacarpophalangeal (MCP), ankle, and second through fifth metatarsophalangeal (MTP) joint and 12-joint US assessments showed the highest correlations with the comprehensive US assessment. The wrist, MCP, ankle, and MTP joint US assessment showed the highest sensitivity for detecting SH and synovial PD signal in patients in remission according to the DAS28 and SDAI as compared to the comprehensive US assessment. Conclusion US assessment of the wrist, MCP, ankle, and MTP joints can be highly sensitive for detecting residual B-mode and Doppler joint inflammation in RA patients.

Prevalence of hypertension in renal disease

Abstract: Background. Hypertension (HTN) is very frequent in patients with renal disease and its prevalence increases as renal failure progresses. Methods. We studied the prevalence of HTN in 1921 patients with different nephropathies. Patients on dialysis and renal transplant patients were not included in the study. HTN was defined as SBP > 140 and/ or DBP > 90 mmHg, or requiring antihypertensive therapy. Results. The prevalence of HTN in the total group of patients with renal diseases was 60.5%, but this prevalence varied widely depending upon the type of underlying nephropathy. The prevalence of HTN was practically universal in patients with renal vascular disease (93%) and in patients with established diabetic nephropathy (87%), and 74% of the patients with polycystic kidney disease, 63% of the patients with chronic pyelonephritis and 54% of the patients diagnosed with glomerulonephritis were hypertensive. The prevalence of HTN in patients with renal insufficiency (80%) is significantly higher than that in patients without renal insufficiency (43% P < 0.001). In a multiple logistic regression analysis, the independent risk factors defining HTN in renal patients were: renal failure, age, the presence of diabetes, hypertriglyceridaemia and proteinuria. Antihypertensive treatment consisted of diet alone in 4% of the patients, one drug in 45%, two drugs in 36%, three medications in 13% and more than three drugs in 2.5%. The angiotensin-converting enzyme (ACE) inhibitors were the most frequently prescribed drug (39% of the patients treated in monotherapy) followed by calcium channel blockers (27%), diuretics (18%) and β-blockers (9%). The most common combined therapy was a diuretic plus an ACE inhibitor. The percentage of patients with BP controlled according to current recommendations for renal patients (BP < 130/85) was very low; SBP in only 49% and DBP in 24%. Control of both was only achieved in 10% of the patients. Conclusions. There is a high prevalence of HTN in renal patients, which depends on the type of nephropathy and the degree of renal failure. Other independent risk factors for HTN in patients with renal disease are: advanced age, the presence of diabetes, hypertriglyceridaemia and the severity of proteinuria. BP control in renal patients is quite poor and should be improved to reduce progression of the renal disease.
