Persistent urinary incontinence and delivery mode history: a six-year longitudinal study

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2006
Christine MacArthur
Objective, To investigate the prevalence of persistent and long term postpartum urinary incontinence and associations with mode of first and subsequent delivery. Design, Longitudinal study. Setting, Maternity units in Aberdeen (Scotland), Birmingham (England) and Dunedin (New Zealand). Population, Women (4214) who returned postal questionnaires three months and six years after the index birth. Methods, Symptom data were obtained from both questionnaires and obstetric data from case-notes for the index birth and the second questionnaire for subsequent births. Logistic regression investigated the independent effects of mode of first delivery and delivery mode history. Main outcome measures, Urinary incontinence,persistent (at three months and six years after index birth) and long term (at six years after index birth). Results, The prevalence of persistent urinary incontinence was 24%. Delivering exclusively by caesarean section was associated with both less persistent (OR = 0.46, 95% CI 0.32,0.68) and long term urinary incontinence (OR = 0.50, 95% CI 0.40,0.63). Caesarean section birth in addition to vaginal delivery, however, was not associated with significantly less persistent incontinence (OR 0.93, 95% CI 0.67,1.29). There were no significant associations between persistent or long term urinary incontinence and forceps or vacuum extraction delivery. Other significantly associated factors were increasing number of births and older maternal age. Conclusions, The risk of persistent and long term urinary incontinence is significantly lower following caesarean section deliveries but not if there is another vaginal birth. Even when delivering exclusively by caesarean section, the prevalence of persistent symptoms (14%) is still high. [source]

Should bulimia nervosa be subtyped by historyof anorexia nervosa?

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue S3 2007
A longitudinal validation
Abstract Objective: To determine whether a past diagnosis of anorexia nervosa (AN) predicts longitudinal course and outcome among women with bulimia nervosa (BN). Method: A subset (n = 176) of participants in the Longitudinal Study of Anorexia and Bulimia Nervosa who met DSM-IV criteria for BN either at study intake (n = 144) or during follow-up (n = 32; 4 had restricting AN at intake, 28 had binge/purge AN at intake) were included in this report. Over a median of 9 years, weekly eating disorder symptom data were collected from participants using the Longitudinal Interview Follow-up Examination, Eating Disorders Version. Results: While there were no between-group differences in likelihood of partial recovery, women with BN who had a history of AN were more likely to have a protracted illness, relapsing into AN during follow-up, compared to those with no AN history who were more likely to move from partial to full recovery. Conclusion: Lifetime AN is an important prognostic indicator among women with BN and these longitudinal data would support the subtyping of BN on the basis of AN history. © 2007 by Wiley Periodicals, Inc.

Fluctuation of gastrointestinal symptoms in the community: a 10-year longitudinal follow-up study

ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2008

Summary Background, There are few studies examining the stability of gastrointestinal symptoms during prolonged periods of follow-up. Aim, To examine this issue in individuals previously recruited into a community screening programme for Helicobacter pylori providing symptom data at study entry. Methods, All traceable participants were sent dyspepsia and IBS questionnaires by post at 10 years. Symptom subgroups were assigned at baseline and 10-year follow-up. Individuals symptomatic at both time points who changed subgroup were compared with those symptomatic and remaining in the same subgroup. Results, Three-thousand eight hundred and nineteen individuals provided data. At baseline, 2417 (63%) were asymptomatic or did not meet diagnostic criteria for a subgroup. Of these, 1648 (68%) remained asymptomatic at 10 years, whilst 769 (32%) reported symptoms. Of the 1402 individuals symptomatic at baseline, 404 (29%) remained in the same subgroup at 10 years, 603 (43%) changed subgroup and symptoms resolved or did not meet criteria for a subgroup in 395 (28%). Symptom stability was more likely in males [odds ratio (OR): 1.50; 99% confidence interval (CI): 0.97,2.31] and older subjects (OR per year: 1.09; 99% CI: 1.01,1.17). Conclusion, Of those subjects symptomatic at baseline, almost three-quarters remained symptomatic at 10 years, but over 40% changed symptom subgroup. [source]

Effect of protective filters on fire fighter respiratory health during simulated bushfire smoke exposure

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 9 2006

Abstract Background Bushfire fighters are potentially subject to risks from bushfire smoke. Although many different protective masks and filters are available, it is not clear which is the most effective from a health and safety perspective. The effect of protective filters on the respiratory health of Western Australian urban career fire fighters under controlled simulated conditions is investigated. Methods Sixty-four healthy Fire and Emergency Services Authority of Western Australia (FESA) urban career fire fighters were subjected to controlled simulated bushfire smoke in an open smoke chamber for 15 min. The fire fighters were allocated one of the three types of protective filters: particulate only (P), particulate/organic vapor (POV), and a particulate/organic vapor/formaldehyde (POVF) filter using a double-blind randomized procedure. Personal air sampling inside the fire fighters' masks, spirometry, oximetry, and self-reported symptom data were collected at baseline and at two time intervals after the smoke exposure. Results A significant decline in oxygen saturation was seen immediately after exposure, however, the decline was small and no significant relationships could be established between this and the type of filter used. A significantly higher number of participants in the P and POV filter groups self-reported an increase in coughing, wheezing, and shortness of breath compared to the POVF group. Air sampling demonstrated a significantly higher level of formaldehyde and acrolein inside the masks fitted with P filters compared to POV and POVF filters. Conclusions Testing the effectiveness of P, POV, and POVF filters under controlled conditions has demonstrated that the POVF filter provides statistically significant better protection for the fire fighters' airways in a simulated bushfire exposure chamber.
