Improvement in Obesity-associated Medical Conditions following Vertical Banded Gastroplasty and Gastrointestinal Bypass

Thirty-nine patients undergoing either Silastictrade mark ring vertical banded gastroplasty (SRVG, n = 23) or Roux-en-Y gastrointestinal bypass (RGB, n = 16) over a 1-year period were analyzed retrospectively. Weight loss averaged 40 kg (89 lb). Clinical diabetes mellitus was markedly improved in seven out of nine patients (p = 0.023). Shortness of breath resolved in all 26 patients who had this condition preoperatively (p < 0.001). Orthopedic problems, high blood pressure, and self-assessment of general health and quality of life were also dramatically improved. We conclude that bariatric surgery serves as an effective method to alleviate a multitude of conditions associated with morbid obesity.

Physical and mental development in 4-6-year-old triplets

A total of 21 families with complete sets of triplets, born within 200 km of Stockholm, were invited to participate in a follow-up study with the aim of assessing the physical and mental development of their triplets at 4-6 years of age. Four families declined to participate in the study and thus the study group consisted of 17 sets of triplets who were born at 33-36 gestational weeks from 1986 to 1989. Mean birth weight was 2104g (range 1310-2670g) for the boys and 1882g (range 1290-2590g) for the girls. At birth, none of the 51 triplets showed any malformations. No asphyxia or other major complications were noted to have occurred at delivery. The children were examined in their homes with a neurological examination and the Griffiths mental development scales (GMDS). No major physical disabilities were found. In a group of triplets born small for dates, the total GMDS score and most of the subscale scores were significantly lower than for their siblings. In contrast to what has been found in singletons and twins, the differences in mental development between triplet boys and girls were not significant. On the whole, physical and mental development did not differ from what has been found in twins and singletons of the same age and with the same birth weight.     

Plasma cytokine levels in necrotizing enterocolitis

Plasma concentrations of tumour necrosis factor (TNF) and interleukin-6 (IL-6) were measured by ELISA in samples taken from 24 infants with necrotizing enterocolitis (NEC) between 0 and 306 h from diagnosis. TNF was detected (>10pg/ml) in 71% samples with a mean of 48pg/ml (95% CI 42 to 55 pg/ml) and did not vary with either time from diagnosis or severity of disease. IL-6 was raised during the first 48 h with a significant difference between stage II (mean 127 pg/ml, 95% CI 10 to 329 pg/ml) and stage HI (mean 3127 pg/ml, 95% CI 1809 to 4445 pg/ml, p = 0.001). Postoperative plasma IL-6 concentration fell to similar levels seen in stage II (mean 150 pg/ml, 95% CI 37 to 283 pg/ ml, p = 0.79). We conclude that plasma concentration of IL-6 rather than TNF reflects the clinical severity of necrotizing enterocolitis and that the relative level of these cytokines has important implications for the use of anti-cytokine therapy in NEC.     

Necrotizing enterocolitis—multisystem organ failure of the newborn?

Evidence of failure of organ system other than the gastrointestinal tract was reviewed in a series of 46 infants treated for necrotizing enterocolitis (NEC) at a regional combined medical and surgical neonatal unit. Respiratory failure was identified in 42 infants (91%), renal failure in 39 (85%), cardiovascular failure in 15 (33%) and hepatic failure in 7 (15%). The number of systems involved correlated with both severity of disease and outcome. Onset of failure in the above systems was closely related to the diagnosis of NEC and 29 cases predated the clinical onset. We conclude that NEC is part of a syndrome of multisystem failure and that this has important implications for the treatment of NEC.     

Assessment of subjective sleep disturbance and related factors during female mid-life with the Jenkins Sleep Scale

Objective

To assess sleep disturbance and related factors among mid-aged women.

Methods

This was a cross-sectional study in which 288 women (40–59 years) were requested to complete the Jenkins Sleep Scale (JSS), the 12-item General Health Questionnaire (GHQ-12), the Menopause Rating Scale (MRS) and a general socio-demographic questionnaire containing female and partner data.

Results

Median [interquartile range] age of the whole sample was 47 [8] years. A 62.2% of women were rural residents, 21.2% were postmenopausal, 20.1% were receiving psychotropic drugs, 64.2% had abdominal obesity (waist ≥ 88 cm), and 9.7% reported intimate violence. A 12.8% had an abnormal GHQ-12 score (total score ≥ 3) whereas 14.2% had severe menopause-related symptoms (total MRS score ≥ 17). The prevalence of disturbed sleep (JSS score ≥ 12) was 37.5%. JSS scores displayed significant differences in relation to menopausal status, presence of stress urinary incontinence, use of psychiatric treatment, intimate partner violence, self-perception of healthiness, and partner factors (perception of healthiness, educational level, and regular exercise). Higher JSS scores (disturbed sleep) positively correlated with GHQ-12 and MRS scores, number of co-morbid conditions, body mass index, and female and partner age. Multiple linear regression analysis found that JSS scores correlated positively with somatic MRS scores and with intimate violence, and inversely with partner educational level (r² = 0.375, p < 0.05).

Conclusion

In this mid-aged female sample, disturbed sleep was related to somatic menopause-related symptoms, intimate violence and partner educational level.
