Dr Mark Porter unpicks the science behind the so called 'weekend effect'. Politicians have quoted research claiming that people are 20% more likely to die of a stroke at the weekend, while another much cited study finds 11,000 more deaths in people admitted at the weekend. But how valid are these figures and the research that generated them? Dr Margaret McCartney reviews the stroke data that has been criticised by experts as being out of date. While Mark Porter talks to Editor of the BMJ, Fiona Godlee, who published the 11,000 figure but is concerned about the political use of the findings. And discusses the study with lead author Nick Freemantle, plus Consultant Surgeon Sam Nashef who is sceptical about the results.

Inside Health listener and keep fit enthusiast, David Heathcote, wanted advice on how far he should safely push himself when he's training in the gym.In this special programme about the health benefits of keeping active, Dr Mark Porter helps David to find the answer to his question about the exercise "sweet spot". If you struggle to screw the top off a jar, or use your arms to push yourself out of your chair, that's a sure fire sign, according to Dr Philip Conaghan, consultant rheumatologist and Professor of Musculoskeletal Medicine at the University of Leeds, that your muscles are weak. And the good news is that building muscle strength will protect your joints, not damage them. Dr Conaghan tells Mark that there's a worrying lack of understanding about the impact of muscle weakness on arthritic joints.Over the last decade there's been a growing interest in the relationship between activity and the risk of developing cancer. Studies have demonstrated that exercise appears to have a protective effect against at least four different cancers (breast cancer, colon cancer, endometrial cancer and some upper gastrointestinal cancers) and that being fit helps recovery from cancer too. Dr Denny Levett, a consultant in peri-operative medicine and critical care at University Hospital, Southampton who has a special interest in the relationship between exercise and health, says the reason for the apparent protective effect of fitness is still being researched but the evidence that the effect exists is now widely accepted. Professor of Clinical Cardiology, Sanjay Sharma from St George's University of London outlines the benefits to our hearts of keeping active and Park Run fan and regular Inside Health contributor, Dr Margaret McCartney, admits how running has become something of an obsession and promises that the evidence shows that when it comes to getting fitter, it's never too late to start.

Prescriptions for nerve drugs pregabalin and gabapentin have risen dramatically in recent years and at the same time, concerns about abuse. Former prisoner and addict "Patrick" tells Dr Mark Porter that "gabbies" or "pregabs" are drugs of choice in jail and Dr Iain Brew, a GP who works in prisons, says misuse is a growing problem and there are examples of doctors being pressurised into prescribing them. Dr Cathy Stannard, consultant in pain medicine at Southmead Hospital in Bristol, chaired an expert group that drew up new prescribing guidelines for pregabalin and gabapentin and she tells Mark that more attention needs to be paid to emerging evidence of misuse. Many women say that if they've had one caesarean section, they feel pressurised to have another one and Sara describes how her medical team planted "a seed of doubt" about the potential risks to her baby which she says for her meant another C-Section was inevitable. But new guidelines from the Royal College of Obstetricians and Gynaecologists spell out that vaginal birth after a previous caesarean is a clinically safe choice, with a 75% success rate, the same as for first-time mothers. Inside Health's Dr Margaret McCartney discusses the history of changing attitudes to natural birth after caesarean and says why the new guidelines should give future mothers the confidence to discuss, well in advance of their birth, the best option for them. How do you fill in health check forms that ask for family history if you don't know who your family was? Inside Health listener Jessica is adopted and her heart health check suggested a very low risk of a stroke or heart attack when she couldn't answer the family history question. Mark and Margaret discuss how common this is, and what difference family knowledge would make to Jessica's risk (not much).Adrenaline auto injectors were first used in the 1960s when they were developed for soldiers to use during nerve gas attacks allowing them to self administer the antidote. But is a device designed to be used by fit, trained soldiers just as suitable for use in children and adults of widely varying size and weight? These concerns were raised by a coroner conducting the inquest into the death of a 19 year old student who died of anaphylactic shock caused by a nut allergy, despite her using her auto injector. The Medicine and Healthcare Products Regulatory Authority and also the European Medicines Agency have been looking into issue and Dr Robert Boyle, allergy specialist at St Mary's Hospital, Paddington and Director of the Paediatric Research Unit at Imperial College, London provided expert advice. He talks to Mark about the limitations of auto injector design and urges everybody who might use the devices to ensure they are confident about exactly how to use them.
