Quality assessment of clinical practice guidelines for chronic kidney disease: a systematic review.

BACKGROUND: Chronic kidney disease (CKD) is a worldwide public health problem. Clinical practice guidelines (CPGs) are being developed and implemented in order to improve clinical practice related to the detection and treatment of CKD. The objective of our study was to evaluate the quality of CPGs regarding the CKD and to examine whether there are factors which influence their quality. METHODS: A systematic search was conducted to identify all CPGs regarding the early diagnosis and treatment of CKD. The CPGs quality were evaluated by three reviewers using the AGREE II instrument to decide if the guidelines are recommended for their use in clinical practice. RESULTS: In total, 13 CPGs were identified: five from America, six from Europe, one from Asia, and one from Oceania. Five CPGs were recommended for their use in clinical practice; since all their domains achieved the medium or high category. Furthermore, six CPGs were recommended with modifications, as the stakeholders' involvement, applicability, and editorial independence domains were evaluated as low category. These domains, as well as the rigor of the development domain, reached the very low category in those CPGs that were not recommended for its use in clinical practice. In all CPGs, the domains with the lowest average were the stakeholder involvement and the applicability. When comparing the domains of the CPGs according to the origin, type of developer group, the checklist used during the development and the publication period, a significantly higher average in the domain stakeholder involvement was found in the CPGs from Asia and Oceania compared to the ones in Latin America. Additionally, a significantly higher average in the applicability domain was found in the CPGs developed by CPGs developer organizations compared to those developed by medical societies. CONCLUSIONS: In total, 85% of the CPGs regarding CKD were recommended or recommended with modifications. The stakeholder involvement and applicability domains are assessed in the low category, which might affect the CPGs implementation. In order to save resources in low- and middle-income countries, an adaptation of the recommended CPGs should be considered.

The effect of additional core stability exercises on improving dynamic sitting balance and trunk control for subacute stroke patients: a randomized controlled trial.

OBJECTIVE: To examine the effect of core stability exercises on trunk control, dynamic sitting and standing balance, gait, and activities of daily living in subacute stroke patients. DESIGN: A randomized controlled trial. SETTING: Inpatient rehabilitation hospital in two centres. SUBJECTS: Eighty patients (mean of 23.25 (±16.7) days post-stroke) were randomly assigned to an experimental group and a control group. INTERVENTIONS: Both groups underwent conventional therapy for five days/week for five weeks and the experimental group performed core stability exercises for 15 min/day. The patients were assessed before and after intervention. MAIN MEASURES: The Trunk Impairment Scale (Spanish-Version) and Function in Sitting Test were used to measure the primary outcome of dynamic sitting balance. Secondary outcome measures were standing balance and gait as evaluated via Berg Balance Scale, Tinetti Test, Brunel Balance Assessment, Postural Assessment Scale for Stroke (Spanish-Version), and activities of daily living using Barthel Index. RESULTS: The experimental group showed statistically significant differences for all of the total scale scores (P<0.05), except for the sitting section of the Brunel Balance Assessment. The mean (SD) difference between groups in Trunk Impairment Scale total score was 3.40 (±4.12) points, and its subscale dynamic sitting balance was 2.28 (±3.29). The Berg Balance Scale was 14.54 (±18.19) points, and the Barthel Index was 13.17 (±25.27) points. Collectively, these results were in favour of the experimental group. CONCLUSIONS: Core stability exercises in addition to conventional therapy improves trunk control, dynamic sitting balance, standing balance, gait and activities of daily living in subacute post-stroke patients.

Association Between Myocardial Injury and Cardiovascular Outcomes of Orthopaedic Surgery: A Vascular Events in Noncardiac Surgery Patients Cohort Evaluation (VISION) Substudy.

BACKGROUND: Myocardial injury after noncardiac surgery (MINS) is common and of prognostic importance. Little is known about MINS in orthopaedic surgery. The diagnostic criterion for MINS was a level of ≥0.03 ng/mL on a non-high-sensitivity troponin T (TnT) assay due to myocardial ischemia. METHODS: We undertook an international, prospective study of 15,103 patients ≥45 years of age who had inpatient noncardiac surgery; 3,092 underwent orthopaedic surgery. Non-high-sensitivity TnT assays were performed on postoperative days 0, 1, 2, and 3. Among orthopaedic patients, we determined (1) the prognostic relevance of the MINS diagnostic criteria, (2) the 30-day mortality rate for those with and without MINS, and (3) the probable proportion of MINS cases that would go undetected without troponin monitoring because of a lack of an ischemic symptom. RESULTS: Three hundred and sixty-seven orthopaedic patients (11.9%) had MINS. MINS was associated independently with 30-day mortality including among those who had had orthopaedic surgery. Orthopaedic patients without and with MINS had a 30-day mortality rate of 1.0% and 9.8%, respectively (odds ratio [OR], 11.28; 95% confidence interval [CI], 6.72 to 18.92). The 30-day mortality rate was increased for patients with MINS who had an ischemic feature (i.e., symptoms, or evidence of ischemia on electrocardiography or imaging) (OR, 18.25; 95% CI, 10.06 to 33.10) and for those who did not have an ischemic feature (OR, 7.35; 95% CI, 3.37 to 16.01). The proportion of orthopaedic patients with MINS who were asymptomatic and in whom the myocardial injury would have probably gone undetected without TnT monitoring was 81.3% (95% CI, 76.3% to 85.4%). CONCLUSIONS: One in 8 orthopaedic patients in our study had MINS, and MINS was associated with a higher mortality rate regardless of symptoms. Troponin levels should be measured after surgery in at-risk patients because most MINS cases (>80%) are asymptomatic and would go undetected without routine measurements. LEVEL OF EVIDENCE: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

Evidence mapping and quality assessment of systematic reviews on therapeutic interventions for oral cancer.

Purpose: This evidence mapping aims to describe and assess the quality of available evidence in systematic reviews (SRs) on treatments for oral cancer. Materials and methods: We followed the methodology of Global Evidence Mapping. Searches in MEDLINE, EMBASE, Epistemonikos and The Cochrane Library were conducted to identify SRs on treatments for oral cancer. The methodological quality of SRs was assessed using the Assessing the Methodological Quality of Systematic Reviews-2 tool. We organized the results according to identified Population-Intervention-Comparison-Outcome (PICO) questions and presented the evidence mapping in tables and a bubble plot. Results: Fifteen SRs met the eligibility criteria, including 118 individual reports, of which 55.1% were randomized controlled clinical trials. Ten SRs scored "Critically low" methodological quality. We extracted 30 PICOs focusing on interventions such as surgery, radiotherapy, chemotherapy, targeted therapy and immunotherapy; 18 PICOs were for resectable oral cancer, of which 8 were reported as beneficial. There were 12 PICOs for unresectable oral cancer, of which only 2 interventions were reported as beneficial. Conclusion: There is limited available evidence on treatments for oral cancer. The methodological quality of most included SRs scored "Critically low". The main beneficial treatment reported by authors for patients with resectable oral cancer is surgery alone or in combination with radiotherapy or chemotherapy. Evidence about the benefits of the treatments for unresectable oral cancer is lacking. These findings highlight the need to address future research focused on new treatments and knowledge gaps in this field, and increased efforts are required to improve the methodology quality and reporting process of SRs on treatments for oral cancer.

Variability of nutrients intake, lipid profile and cardiovascular mortality among geographical areas in Spain: The DRECE study.

It has often been suggested that cardiovascular mortality and their geographical heterogeneity are associated with nutrients intake patterns and also lipid profile. The large Spanish study Dieta y Riesgo de Enfermedades Cardiovasculares en España (DRECE) investigated this theory from 1991 to 2010. Out of the 4,783 Spanish individuals making up the DRECE cohort, 220 subjects (148 men and 72 women) died (4.62%) during the course of the study. The mean age of patients who died from cardiovascular causes (32 in all) was 61.08 years 95% CI (57.47-64.69) and 70.91% of them were males. The consumption of nutrients and the lipid profile by geographical area, studied by geospatial models, showed that the east and southern area of the country had the highest fat intake coupled to a high rate of unhealthy lipid profile. It was concluded that the spatial geographical analysis showed a relationship between high fat intake, unhealthy lipid profile and cardiovascular mortality in the different geographical areas, with a high variability within the country.

[Interventions based on exercise and physical environment for preventing falls in cognitively impaired older people living in long-term care facilities: A systematic review and meta-analysis]. / Intervenciones basadas en el ejercicio y el entorno para la prevención de caídas en personas con deterioro cognitivo que viven en centros de cuidado: revisión sistemática y metaanálisis.

This systematic review aims to report the effectiveness of interventions based on exercise and/or physical environment for reducing falls in cognitively impaired older adults living in long-term care facilities. In July 2014, a literature search was conducted using main databases and specialised sources. Randomised controlled trials assessing the effectiveness of fall prevention interventions, which used exercise or physical environment among elderly people with cognitive impairment living in long-term care facilities, were selected. Two independent reviewers checked the eligibility of the studies, and evaluated their methodological quality. If it was adequate, data were gathered. Fourteen studies with 3,539 participants using exercise and/or physical environment by a single or combined approach were included. The data gathered from studies that used both interventions showed a significant reduction in fall rate. Further research is needed to demonstrate the effectiveness of those interventions for preventing falls in the elderly with cognitive impairment living in long-term care establishments.

Systematic review of megestrol acetate in the treatment of anorexia-cachexia syndrome.

This study aimed to assess the efficacy and safety of megestrol acetate (MA) in anorexia-cachexia syndrome (ACS). Literature and relevant databases were searched for randomized controlled trials of MA to treat ACS in patients with cancer, AIDS, or other pathologies. Data were extracted by two independent reviewers, and meta-analyses were performed where possible. Twenty-six studies were included (n=3,887). Compared to placebo, MA increased appetite in oncology patients [RR=2.31 (95% CI 1.52-3.59)], led to weight gain [RR=1.88 (95% CI 1.43-2.47)] and improved HRQOL [RR=1.52 (95% CI 1.00-2.30)]. In AIDS patients, it increased weight [RR=2.16 (95% CI 1.45-3.21)]. MA showed significant benefits over dronabinol in improving appetite, but no statistically significant advantages over other drugs for treating ACS were observed. There were no appreciable differences between lower (<800 mg/day) and higher (>800 mg/day) doses of MA. Few serious adverse events were recorded. MA is an effective and safe treatment for ACS in cancer and AIDS patients, particularly in terms of improvement in appetite and weight gain.

Esta revisión evalúa la efectividad de las intervenciones que utilizan el ejercicio y/o la modificación ambiental para la prevención de caídas en ancianos institucionalizados con deterioro cognitivo. Durante julio de 2014 se consultaron las principales bases bibliográficas y recursos especializados sobre el tema. Se seleccionaron ensayos controlados aleatorizados sobre intervenciones destinadas a prevenir caídas, que incluían el ejercicio físico y/o modificaciones del entorno, aplicadas en esta población. Dos revisores valoraron independientemente la elegibilidad y la calidad metodológica de los estudios. Se agruparon los datos cuando fue adecuado. Se identificaron 14 estudios con 3.539 participantes que utilizaban el ejercicio y/o la modificación ambiental de forma única o combinada con otras intervenciones. Ambas intervenciones demostraron efectividad en la reducción del número de caídas, desde un enfoque combinado. No obstante, hacen falta más estudios para asegurar la efectividad del uso del ejercicio y del entorno para la prevención de caídas en esta población (AU)
