Management of diabetes from preconception to the postnatal period: summary of NICE guidance

Diabetes in pregnancy is associated with risks to the woman (for example, higher rates of miscarriage, preeclampsia, and preterm labour) and to the developing fetus and baby (for example, higher rates of congenital malformations, macrosomia, birth injury, and perinatal mortality). This article summarises the most recent guidance from the National Institute for Health and Clinical Excellence (NICE) on how to manage diabetes and its complications from preconception to the postnatal period

The associations of sedentary time and breaks in sedentary time with 24-hour glycaemic control in type 2 diabetes

The aim of this study was to investigate the associations of accelerometer-assessed sedentary time and breaks in sedentary time with 24-h events and duration of hypoglycaemia (7.8 mmol/l) and above target glucose (>9 mmol/l). Thirty-seven participants with type 2 diabetes (age, 62.8 ± 10.5 years; body mass index, 29.6 ± 6.8 kg/m2) in Glasgow, United Kingdom were enrolled between February 2016 and February 2017. Participants wore an activity monitor (activPAL3) recording the time and pattern of sedentary behaviour and a continuous glucose monitoring (CGM, Abbott FreeStyle Libre) for up to 14 days. Linear regression analyses were used to investigate the associations. Participants spent 3.7%, 64.7%, 32.1% and 19.2% of recording h/day in hypoglycaemia, euglycaemia, hyperglycaemia and above target, respectively. There was a negative association between sedentary time and time in euglycaemia (β = -0.44, 95% CI -0.86; -0.03, p = 0.04). There was a trend towards a positive association between sedentary time and time in hyperglycaemia (β = 0.36, 95% CI -0.05; 0.78, p = 0.08). Breaks in sedentary time was associated with higher time in euglycaemia (β = 0.38, 95% CI 0.00; 0.75, p = 0.04). To conclude, in individuals with type 2 diabetes, more time spent in unbroken and continuous sedentary behaviour was associated with poorer glucose control. Conversely, interrupting sedentary time with frequent breaks appears to improve glycaemic control. Therefore, this should be considered as a simple adjunct therapy to improve clinical outcomes in type 2 diabetes

Cancer Surveillance Guideline for individuals with PTEN hamartoma tumour syndrome.

PTEN hamartoma tumour syndrome is a diverse multi-system disorder predisposing to the development of hamartomatous growths, increasing risk of breast, thyroid, renal cancer, and possibly increasing risk of endometrial cancer, colorectal cancer and melanoma. There is no international consensus on cancer surveillance in PHTS and all current guidelines are based on expert opinion. A comprehensive literature review was undertaken and guidelines were developed by clinicians with expertise from clinical genetics, gynaecology, endocrinology, dermatology, radiology, gastroenterology and general surgery, together with affected individuals and their representatives. Recommendations were put forward for surveillance for breast, thyroid and renal cancers. Limited recommendations were developed for other sites including endometrial, colon and skin. The proposed cancer surveillance recommendations for PHTS require a coordinated multidisciplinary approach and significant patient commitment. The evidence base for cancer surveillance in this guideline are limited, emphasising the need for prospective evaluation of the effectiveness of surveillance in the PHTS population

Acute kidney injury: an acceptable risk of treatment with renin-angiotensin system blockade in primary care?

Background: Use of renin-angiotensin system (RAS) blockade has become increasingly widespread driven by evidence-based guidance. There is concern about the role of these agents in the genesis of avoidable acute kidney injury (AKI). Objectives: To investigate the association between AKI and use of RAS blockade. Design: Multilevel hierarchical analysis of a large cohort of patients registered with UK general practitioners. Setting: Primary care practices in East and West Kent, United Kingdom. Patients: 244,715 patients from 27 practices. Measurements: Demographic, clinical, biochemical and prescription data. Methods: Analyses of data acquired between 02/3/2004 and 17/04/2012 using multilevel logistic regression to determine the relationship between AKI and use of RAS blockade; further analysed by indication for treatment with RAS blockade. Results: Sufficient serum creatinine data were available to define AKI in 63,735 patients with 208,275 blood test instances. In 95,569 instances the patient was prescribed a RAS antagonist of which 5.4% fulfilled criteria for AKI. The unadjusted odds ratio (OR) for AKI in those prescribed RAS blockade was 1.93 (1.81-2.06, 95%CI) falling to 1.11 (1.02-1.20, 95%CI) when adjusted for age, gender, co-morbidity, GFR category, proteinuria, systolic blood pressure and diuretic therapy. In patients with an evidence-based indication there was no difference in absolute risk of AKI. However, prescription of RAS blockade in the absence of indication appeared to be associated with greater risk of AKI. When analysis was repeated with AKIN2/AKIN3 as the outcome, although risk of AKI remained significant when unadjusted (OR 1.73, 95%CI 1.42-2.11, p<0.001), after full adjustment there was no increased risk (OR 0.83, 95%CI 0.63-1.09) in those taking RAS antagonists. However, when analysed by indication AKIN2/AKIN3 was significantly more likely in those prescribed RAS antagonists without indication (OR 2.04, 95%CI 1.41-2.94, p<0.001). Limitations: Observational database study. No information concerning hospitalisation. Prescribing assumptions and potential inaccurate coding. Potential survival bias; patients surviving longer will contribute more data. Conclusions: Use of RAS antagonists increased the risk of AKI, independent of common confounding variables. After correction for confounders the risk fell away and became non-significant for moderate and severe AKI. However, where there was no evidence-based indication for RAS antagonists the risk of AKI, whether mild, moderate or severe, remained greater

Guía de práctica clínica sobre el diagnóstico y tratamiento de la hiponatremia

La hiponatremia se define como una concentración sérica de sodio <135 mmol/L y es el trastorno hidroelectrolítico más frecuente en la práctica clínica. La hiponatremia puede causar un amplio espectro de síntomas clínicos, desde sutiles hasta graves o incluso mortales, y se asocia con aumento de la morbimortalidad y prolongación de la estancia hospitalaria. A pesar de ello, el manejo de los pacientes con hiponatremia sigue siendo problemático. La prevalencia de hiponatremia en enfermedades muy diferentes y su manejo por muy diversos especialistas han fomentado la existencia de protocolos de diagnóstico y tratamiento muy diversos, que varían con la especialidad y la institución. La Sociedad Europea de Medicina Intensiva (ESICM), la Sociedad Europea de Endocrinología (ESE) y la Asociación Renal Europea-Asociación Europea de Diálisis y Trasplante (ERA-EDTA), representada por la European Renal Best Practices (ERBP), han desarrollado la guía de práctica clínica sobre el enfoque diagnóstico y tratamiento de la hiponatremia como una empresa conjunta de las 3 sociedades que representan a los especialistas con un interés natural en la hiponatremia, a fin de ofrecer una visión común y holística del abordaje del problema. Además de ofrecer un enfoque riguroso en la metodología y la evaluación de la evidencia, el documento está centrado en resultados importantes para el paciente y en facilitar una herramienta útil para los médicos en la práctica clínica cotidiana. Presentamos ahora una versión abreviada de las recomendaciones y sugerencias sobre el diagnóstico y el tratamiento de la hiponatremia recogidas en la guía completa

Guideline summary: assessment, diagnosis, care and support for people with dementia and their carers [Scottish Intercollegiate Guidelines Network SIGN Guideline 168].

The Scottish Intercollegiate Guidelines Network (SIGN) have recently published their guideline SIGN168 on 'Assessment, Diagnosis, Care, and Support for People with Dementia and their Carers'. The guideline makes evidence-based recommendations for best practice in the assessment, care and support of adults living with dementia. Topics featured in this guideline are limited to those prioritised by stakeholders, especially people with lived and living experience, and those not well covered under pre-existing guidance. We summarise the guideline recommendations related to identification and diagnosis of dementia, investigative procedures, postdiagnostic support living with dementia, including non-pharmacological approaches for distressed behaviours, using technology to support people with dementia, grief and dementia and changing needs of people with dementia. The guideline content is summarised as officially published, with additional commentary in the final section
