Appetite regulation: from the gut to the hypothalamus

Abstract: these proportions had increased to 26% and 22%, respectively, with 55% of women and 66% of men being overweight (BMI > 25 kg/m 2 ; Health Survey for England, 2001), reflecting a worldwide trend which is most marked in, but not restricted to, the developed world. Most of us in affluent countries live in a privileged land of plenty where high calorie foods are easily available and in which we have a limited need for exercise. The rising prevalence of obesity in children is of particular concern (Chinn & Rona, 2001).

Importance of maternal history of non-insulin dependent diabetic patients.

Abstract: OBJECTIVE--To assess the family history of diabetes in non-insulin dependent diabetes mellitus with particular emphasis on parental phenotype. DESIGN--Family histories were obtained from an existing computerised database and supplemented by postal questionnaires. SETTING--Diabetic service of a provincial teaching hospital. SUBJECTS--A total of 1326 patients with non-insulin dependent diabetes who had been referred to diabetic clinics over the past 10 years and from whom data had been collected for inclusion in the database, of whom 347 had affected first degree relatives. Nineteen non-white patients were excluded because of the differential hereditability of the disease, and 230 (70%) patients with an affected first degree relative responded to the postal questionnaire. RESULTS--Mothers were implicated in significantly more cases than fathers in patients with a single affected parent: 125 mothers and 48 fathers from database; 82 mothers and 34 fathers from postal questionnaire; p less than 0.001 in both cases. CONCLUSIONS--Maternal influences seem to have an important role in the inheritance of non-insulin dependent diabetes.

Interventions for treating chronic pelvic pain in women

Abstract: Background: Chronic pelvic pain is common in women in the reproductive and older age groups and causes disability and distress. Often investigation by laparoscopy reveals no obvious cause for the pain. As the pathophysiology of chronic pelvic pain is not well understood its treatment is often unsatisfactory and limited to symptom relief. Currently the main approaches to treatment include counselling or psychotherapy, attempts to provide reassurance by using laparoscopy to exclude serious pathology, progestogen therapy such as medroxyprogesterone acetate, and surgery to interrupt nerve pathways. Objectives: We aimed to identify and review treatments for chronic pelvic pain in women. The review included studies of patients with a diagnosis of pelvic congestion syndrome or adhesions but excluded those with pain known to be caused by i) endometriosis, ii) primary dysmenorrhoea (period pain), iii) pain due to active chronic pelvic inflammatory disease, or iv) irritable bowel syndrome. Search strategy: We searched the Cochrane Menstrual Disorders and Subfertility Group Specialised Register of trials (searched 20th January 2005), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2005), and reference lists of articles. Selection criteria: Randomised controlled trials (RCTs) with women who had chronic pelvic pain. The review authors were prepared to consider studies of any intervention including lifestyle, physical, medical, surgical and psychological treatments. Outcome measures were pain rating scales, quality of life measures, economic analyses and adverse events. Data collection and analysis: For each included trial, information was collected including the method of randomisation, allocation concealment and blinding. Data were extracted independently by the two review authors using forms designed according to the Cochrane guidelines. Main results: Nineteen studies were identified of which fourteen were of satisfactory methodological quality. Five studies were excluded. Progestogen (medroxyprogesterone acetate) was associated with a reduction of pain during treatment while goserelin gave a longer duration of benefit. Counseling supported by ultrasound scanning was associated with reduced pain and improvement in mood. A multidisciplinary approach was beneficial for some outcome measures. Benefit was not demonstrated for adhesiolysis (apart from where adhesions were severe), uterine nerve ablation, sertraline or photographic reinforcement after laparoscopy. Writing therapy and static magnetic field therapy showed some evidence of short-term benefit. Authors' conclusions: The range of proven effective interventions for chronic pelvic pain remains limited and recommendations are based largely on single studies. Given the prevalence and healthcare costs associated with chronic pelvic pain in women, randomised controlled trials of other medical, surgical and psychological interventions are urgently required. Chronic pelvic pain is common in women in the reproductive and older age groups and it causes disability and distress that result in significant costs to health services. The pathogenesis of chronic pelvic pain is poorly understood. Often investigation by laparoscopy reveals no obvious cause for the pain. There are several possible explanations for chronic pelvic pain including undetected irritable bowel syndrome, and central sensitisation of the nervous system. A vascular hypothesis proposes that pain arises from dilated pelvic veins in which blood flow is markedly reduced. As the pathophysiology of chronic pelvic pain is not well understood, its treatment is often unsatisfactory and limited to symptom relief. Currently the main approaches to treatment include counseling or psychotherapy, attempts to provide reassurance using laparoscopy to exclude serious pathology, progestogen therapy such as with medroxyprogesterone acetate and surgery to interrupt nerve pathways.

Low Serum Mannose-Binding Lectin Level Increases the Risk of Death due to Pneumococcal Infection

Abstract: BACKGROUND Previous studies have shown associations between low mannose-binding lectin (MBL) level or variant MBL2 genotype and sepsis susceptibility. However, MBL deficiency has not been rigorously defined, and associations with sepsis outcomes have not been subjected to multivariable analysis. METHODS We reanalyzed MBL results in a large cohort with use of individual data from 4 studies involving a total of 1642 healthy control subjects and systematically defined a reliable deficiency cutoff. Subsequently, data were reassessed to extend previous MBL and sepsis associations, with adjustment for known outcome predictors. We reanalyzed individual data from 675 patients from 5 adult studies and 1 pediatric study of MBL and severe bacterial infection. RESULTS XA/O and O/O MBL2 genotypes had the lowest median MBL concentrations. Receiver operating characteristic analysis revealed that an MBL cutoff value of 0.5 microg/mL was a reliable predictor of low-producing MBL2 genotypes (sensitivity, 82%; specificity, 82%; negative predictive value, 98%). MBL deficiency was associated with increased likelihood of death among patients with severe bacterial infection (odds ratio, 2.11; 95% confidence interval, 1.30-3.43). In intensive care unit-based studies, there was a trend toward increased risk of death among MBL-deficient patients (odds ratio, 1.58; 95% confidence interval, 0.90-2.77) after adjustment for Acute Physiology and Chronic Health Enquiry II score. The risk of death was increased among MBL-deficient patients with Streptococcus pneumoniae infection (odds ratio, 5.62; 95% confidence interval, 1.27-24.92) after adjustment for bacteremia, comorbidities, and age. CONCLUSIONS We defined a serum level for MBL deficiency that can be used with confidence in future studies of MBL disease associations. The risk of death was increased among MBL-deficient patients with severe pneumococcal infection, highlighting the pathogenic significance of this innate immune defence protein.
