Non-steroidal anti-inflammatory drugs and chronic kidney disease progression: a systematic review

BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are widely regarded as one risk factor, which influences chronic kidney disease (CKD) progression. However, previous literature reviews have not quantified the risk in moderate to severe CKD patients. OBJECTIVE To estimate the strength of association between chronic NSAID use and CKD progression. METHODS We conducted a systematic review and meta-analysis of observational general practice or population studies featuring patients aged 45 years and over. The electronic databases searched were MEDLINE, EMBASE, Cochrane, AMED, BNI and CINAHL until September 2011 without date or language restrictions. Searches included the reference lists of relevant identified studies, WEB of KNOWLEDGE, openSIGLE, specific journals, the British Library and expert networks. For relevant studies, random effects meta-analysis was used to estimate the association between NSAID use and accelerated CKD progression (estimated glomerular filtration rate decline ≥ 15 ml/min/1.73 m2). RESULTS From a possible 768 articles, after screening and selection, seven studies were identified (5 cohort, 1 case-control and 1 cross-sectional) and three were included in the meta-analysis. Regular-dose NSAID use did not significantly affect the risk of accelerated CKD progression; pooled odds ratio (OR) = 0.96 (95%CI: 0.86-1.07), but high-dose NSAID use significantly increased the risk of accelerated CKD progression; pooled OR = 1.26 (95%CI: 1.06-1.50). CONCLUSIONS The avoidance of NSAIDs in the medium term is unnecessary in patients with moderate to severe CKD, if not otherwise contraindicated. As the definition of high-dose of NSAID use remains unclear, the lowest effective dose of NSAIDs should be prescribed where indicated.

Children's specific fears

BACKGROUND Most children experience some degree of fear during their development. Specific fears are considered as an appropriate response provided that they are proportionate to the intensity of the perceived threat. Our aim is to present the prevalence of specific fears among children in the Great Britain, their socio-demographic correlates, in particular their association with ethnicity. METHODS Data on the childs experience of specific fears were obtained from parents of a national representative sample of 5- to 16-year-olds using the Development and Well-Being Assessment. Biographic, socio-demographic and socioeconomic characteristics of the child and the family were included in the questionnaire. RESULTS About one-third of children were assessed by their parents as having at least one of 12 specific fears. The most commonly reported fears were animals (11.6%), blood/injections (10.8%) and the dark (6.3%). Just less than 1% of all children were assessed according to International Classification of Diseases research diagnostic criteria as having a specific phobia. Biographic, socio-demographic and socioeconomic factors were independently associated with a greater likelihood of a child having particular fears. The most marked associations were fears of the dark, loud noises, imagined supernatural beings in younger children and fear of animals among girls and all non-white groups. CONCLUSIONS Although fears are only labelled as phobias when they impair functioning and interfere with life, they can cause personal distress to children and also can interfere with their daily activities. Childrens fears differ in nature across different ethnic groups. Culturally mediated beliefs, values and traditions may play a role in their expression.

Outcome measures in intervention trials for adults with autism spectrum disorders; a systematic review of assessments of core autism features and associated emotional and behavioural problems.

A systematic review was conducted of outcome measures used in treatment trials for older adolescents and adults with autism spectrum disorders (ASDs). Of 818 titles only 30 articles (19 of which involved pharmacological treatments) were identified that met inclusion criteria (sample size > 5; mean age of group > 15 years; mean IQ > 30; ASD diagnosis confirmed; use of objective ASD outcome measures; focus on symptoms core to or typically associated with ASDs). Selected studies included randomized and placebo‐controlled trials, retrospective assessment studies, case series and open label or case‐control trials. Use of outcome measures varied with frequent use of non‐standardized assessments, very little use of measures designed specifically for individuals with ASD or of instruments focusing on core ASD deficits, such as communication or social functioning. Most commonly used were the Clinical Global Impression (CGI) rating scale and the Yale–Brown Obsessive Compulsive Scale (Y‐BOCS). The strengths or deficiencies of the outcome measures used were not systematically evaluated.

Heart Failure and Chronic Obstructive Pulmonary Disease Multimorbidity at Hospital Discharge Transition: a Study of Patient and Carer Experience

Care for patients with multimorbidity represents a major challenge not only for patients and carers but to health‐care systems. Hospital discharge transition is a critical point at which challenges for multimorbidity may amplify.

Multi-drug therapy in chronic condition multimorbidity: a systematic review

BACKGROUND Older populations often suffer from multimorbidity and guidelines for each condition are often associated with recommended drug therapy management. Yet, how different and specific multimorbidity is associated with number and type of multi-drug therapies in general populations is unknown. AIM The aim of this systematic review was to synthesize the current evidence on patterns of multi-drug prescribing in family practice. METHODS A systematic review on six common chronic conditions: diabetes mellitus, cardiovascular disease, cerebrovascular disease, chronic obstructive pulmonary disease (COPD), osteoarthritis and depression was conducted, with a focus on studies which looked at any potential combination of two or more multimorbidity. Studies were identified from searches of MEDLINE, EMBASE, PsychINFO, the Allied and Complementary Medicine Database (AMED) and the Health Management Information Consortium (HMIC) databases from 1960 to 2013. RESULTS A total of eleven articles were selected based on study criteria. Our review identified very few specific studies which had explicitly investigated the association between multimorbidity and multi-drug therapy. Relevant chronic conditions literature showed nine observational studies and two reviews of comorbid depression drug treatment. Most (seven) of the articles had focused on the chronic condition and comorbid depression and whether antidepressant management had been optimal or not, while four studies focused on other multimorbidities mainly heart failure, COPD and diabetes. CONCLUSIONS Very few studies have investigated associations between specific multimorbidity and multi-drug therapy, and most currently focus on chronic disease comorbid depression outcomes. Further research needs to identify this area as key priority for older populations who are prescribed high levels of multiple drug therapy.

Evaluating the functional results and complications of autograft vs allograft use for reconstruction of the anterior cruciate ligament: a systematic review

The aim of our review is to identify the reconstruction technique that has a superior functional outcome and decreased number of complications for the anterior cruciate ligament (ACL). We have divided our review into 2 sections. Our primary question evaluates the functional results and complications of autografts compared to allografts for ACL reconstruction. Our subsidiary question evaluates the functional results and complications of bone-patellar tendon-bone (BPTB) autografts compared to hamstring tendon autografts. We conducted a systematic review (SR) based on high quality evidence provided by Cochrane, PubMed and National Health Service evidence searches for papers comparing different ACL reconstruction techniques. Results from 2 primary studies, 1 SR and 1 meta-analysis showed no significant statistical difference when comparing clinical outcomes such as pain, range of motion, laxity, International Knee Documentation Committee score, single assessment numerical evaluation score, Tegner activity score and patient reported satisfaction with regards to autografts vs allografts. Allografts had worse outcomes for postoperative tibial tunnelling and graft failure. Results of 3 SRs showed statistically significant differences in incidence of anterior knee pain, kneeling pain and knee stability, which were all found to be greater amongst those who had received a BPTB autograft. Knee extension was significantly reduced in patients with BPTB grafts when compared to patients with Hamstring tendon autografts. However, with regards to return to prior levels of activity, there was no statistically significant difference between those that received BPTB autografts and those that received Hamstring tendon autografts. Autograft reconstruction of the ACL was shown to provide better postoperative outcomes when compared to allograft reconstruction, although the difference was not statistically significant. When researching different autograft options BPTB autografts were associated with greater pain but also greater stability of the knee joint postoperatively when compared to hamstring tendon autografts.

Past speculations of the future: a review of the methods used for forecasting emerging health technologies

Objectives Forecasting can support rational decision-making around the introduction and use of emerging health technologies and prevent investment in technologies that have limited long-term potential. However, forecasting methods need to be credible. We performed a systematic search to identify the methods used in forecasting studies to predict future health technologies within a 3–20-year timeframe. Identification and retrospective assessment of such methods potentially offer a route to more reliable prediction. Design Systematic search of the literature to identify studies reported on methods of forecasting in healthcare. Participants People are not needed in this study. Data sources The authors searched MEDLINE, EMBASE, PsychINFO and grey literature sources, and included articles published in English that reported their methods and a list of identified technologies. Main outcome measure Studies reporting methods used to predict future health technologies within a 3–20-year timeframe with an identified list of individual healthcare technologies. Commercially sponsored reviews, long-term futurology studies (with over 20-year timeframes) and speculative editorials were excluded. Results 15 studies met our inclusion criteria. Our results showed that the majority of studies (13/15) consulted experts either alone or in combination with other methods such as literature searching. Only 2 studies used more complex forecasting tools such as scenario building. Conclusions The methodological fundamentals of formal 3–20-year prediction are consistent but vary in details. Further research needs to be conducted to ascertain if the predictions made were accurate and whether accuracy varies by the methods used or by the types of technologies identified.

Analgesia dose prescribing and estimated glomerular filtration rate decline: a general practice database linkage cohort study.

Objective We aimed to quantify the short-term effect of non-steroidal anti-inflammatory drugs (NSAIDs), aspirin and paracetamol analgesia dose prescribing on estimated glomerular filtration rate (eGFR) decline in the general practice population. Design A population-based longitudinal clinical data linkage cohort study. Setting Two large general practices in North Staffordshire, UK. Participants Patients aged 40 years and over with ≥2 eGFR measurements spaced ≥90 days apart between 1 January 2009 and 31 December 2010 were selected. Exposure Using WHO Defined Daily Dose standardised cumulative analgesia prescribing, patients were categorised into non-user, normal and high-dose groups. Outcome measure The primary outcome was defined as a >5 mL/min/1.73 m2/year eGFR decrease between the first and last eGFR. Logistic regression analyses were used to estimate risk, adjusting for sociodemographics, comorbidity, baseline chronic kidney disease (CKD) status, renin-angiotensin-system inhibitors and other analgesia prescribing. Results There were 4145 patients (mean age 66 years, 55% female) with an analgesia prescribing prevalence of 17.2% for NSAIDs, 39% for aspirin and 22% for paracetamol and stage 3–5 CKD prevalence was 16.1% (n=667). Normal or high-dose NSAID and paracetamol prescribing was not significantly associated with eGFR decline. High-dose aspirin prescribing was associated with a reduced risk of eGFR decline in patients with a baseline (first) eGFR ≥60 mL/min/1.73 m2; OR=0.52 (95% CI 0.35 to 0.77). Conclusions NSAID, aspirin and paracetamol prescribing over 2 years did not significantly affect eGFR decline with a reduced risk of eGFR decline in high-dose aspirin users with well-preserved renal function. However, the long-term effects of analgesia use on eGFR decline remain to be determined.

Barriers and facilitators to preventive interventions for the development of obstetric fistulas among women in sub-Saharan Africa: a systematic review

BackgroundObstetric fistula is a debilitating childbearing injury that results from poorly managed obstructed labour, leading to the development of holes between the vagina and bladder and/or rectum. Effects of this injury are long-lasting, as women become incontinent and are often marginalised from their communities. Despite continuous occurrence of this injury in lower-income countries, it is preventable, as evidenced in high-income countries. This systematic review aims to identify and understand barriers and facilitators to interventions aimed at the prevention of obstetric fistulas in sub-Saharan African women.MethodsElectronic databases and grey literature were searched. We included studies written in English that discussed interventions to prevent obstetric fistulas implemented in sub-Saharan Africa, and their associated barriers and facilitators. Quality of the studies was assessed, and data including: country of implementation, preventive interventions, and barriers and facilitators to the interventions were extracted. They were then categorised based on the Three Phase Delay Model.ResultsOur search yielded 537 studies, of which 18 were included from sub-Saharan countries including Ethiopia, Nigeria, and Zambia. The most noted barrier to prevention addressed the first phase of delay: the decision to seek care, particularly lack of awareness of the dangers of unsupervised labours. The most noted facilitator addressed the decision to seek care and the quality of care received at a facility, through partnerships between health facilities and governments, and other organisations that provided both financial and resource support.ConclusionDespite being categorised by the three phases of the delay model, barriers and facilitators were found to play a role in multiple phases. The topic of obstetric fistula needs to be researched more extensively, particularly the effectiveness of preventive interventions.

Effectiveness of health education as an intervention designed to prevent female genital mutilation/cutting (FGM/C): a systematic review

BackgroundFemale Genital Mutilation/Cutting (FGM/C) is a harmful practice that violates the human rights of women and girls. Despite global efforts to restrict the practice, there have been few reports on major positive changes to the problem. Health education interventions have been successful in preventing various health conditions and promoting service use. They have also been regarded as promising interventions for preventing FGM/C. The objective of this systematic review is to synthesise findings of studies about effectiveness of health education as an intervention to prevent FGM/C.MethodsThe electronic databases searched were MEDLINE, EMBASE, Cochrane library, Web of Science, Psych INFO, CINAHL and ASSIA. Our search included papers published in the English language without date limits. Study quality was assessed using the Mixed Methods Appraisal Tool (MMAT). A predesigned data recording form was used to extract data from the included studies which were summarised by comparing similar themes.ResultsTwelve out of 359 individual studies met our inclusion criteria. Seven studies were quantitative, three were qualitative and two used mixed methods. Six studies tested before and after the interventions, four studies assessed the effectiveness of previous interventions used by different research teams and two studies endorsed the intervention. Four main factors emerged and were associated with facilitating or hindering the effectiveness of health education interventions: sociodemographic factors; socioeconomic factors; traditions and beliefs; and intervention strategy, structure and delivery.ConclusionsIt is vital to target factors associated with facilitating or hindering the effectiveness of health education for FGM/C. This increases the possibility of effective, collective change in behaviour and attitude which leads to the sustainable prevention of FGM/C and ultimately the improved reproductive health and well-being of individuals and communities.
